Diagnosis On Stomach Cancer Survival Health And Social Care Essay

Stomach Cancer is one of the 20 most common malignant neoplastic diseases in the UK. Survival from tummy malignant neoplastic disease has been increasing in the past 30 old ages, nevertheless at that place remains to be survival differences between different socio-economic categories. The endurance in more disadvantaged categories has remained lower than endurance from the more flush categories ( this difference is known as the want spread ) and more so important in males. Methods: A complete dataset of 70370 malignant neoplastic disease patients that was formed from the malignant neoplastic disease register dataset and merged with Hospital Episode Statistics ( HES ) dataset. The extra jeopardy patterning attack was used ; utilizing the construct of flexible parametric patterning with restricted three-dimensional splines was used to predict net endurance from tummy malignant neoplastic disease. Consequences: The net endurance was found to differ between different want classs, where cyberspace endurance was lower in the most disadvantaged category and the highest in the most flush category. The net endurance was found to be higher in females than males and was found to be about twice every bit much in patients who had surgery. Decision: It was found that although net endurance about doubled in patients who had surgery, the want spread still remained. However farther analysis which include phase and class of malignant neoplastic disease would assist in placing whether this want spread is in fact important after taking into history such variables.

This growing in cells occurs many old ages before the malignant neoplastic disease can be detected. The cancerous cells lose legion indispensable control systems due to mutant in the cistrons of normal cells. When human cells reproduce, mutant can go on by opportunity, nevertheless a figure of different mutants occur before malignant neoplastic disease cells are formed. There are three cistrons which can do malignant neoplastic disease cells ; transforming genes ( besides known as ‘cancer cistrons ‘ which are unnatural and do the cells to multiply or duplicate ) , tumour suppresser cistrons ( cistrons which stop the cells multiplying nevertheless if damaged halt working hence cells become cancerous ) and DNA fix cistrons ( cistrons which repair other damaged cistrons nevertheless if damaged so mutants can non be repaired and therefore when the cell multiplies and divides it copies the mutants ) . ( 1 ) Stomach malignant neoplastic disease is the malignant neoplastic disease that occurs in the tummy and is besides known as stomachic malignant neoplastic disease. There are a figure of different types of tummy malignant neoplastic diseases. The most common type of tummy malignant neoplastic disease is known as glandular cancer of the tummy which starts in the secretory organ cells of the tummy liner, the secretory organ cells so produce stomach fluids and mucous secretion. Other types of tummy malignant neoplastic disease include ; Squamous cell malignant neoplastic diseases ; formed in the squamous cells ( skin cells that are between the secretory organ cells which form the tummy liner ) ( 2 ) . Lymphoma of the tummy ; really rare and is a different type of malignant neoplastic disease in which white blood cells ( lymph cells ) become cancerous cells and can non assist support the organic structure like normal white blood cells ( 2 ) . Gastrointestinal tummy tumor ( GIST ) ; a rare tumor which grows from the cells of the connective tissue which uphold the variety meats of the digestive ( GI ) piece of land and can be both cancerous and non-cancerous ) ( 2 ) . Neuroendocrine tumor ; are rare tumour which grows in the tissues that produce endocrines in the digestive system and can be cancerous and non-cancerous ( 2 ) . The early symptoms of tummy malignant neoplastic disease are non-specific and include dyspepsia, sourness and belch, experiencing full Oklahoman and hence ensuing in loss of weight, shed blooding in the tummy which can do anemia and hence doing fatigue and paler tegument. Other symptoms include purging, blood coagulums, hurting in the upper venters or hurting under the chest bone and trouble in get downing. Symptoms of the advanced phase of the malignant neoplastic disease, include blood in the stool and development of fluid in the venters ( 3 ) . There are no testing programme for tummy malignant neoplastic disease in the UK, nevertheless tummy malignant neoplastic disease is the most common malignant neoplastic disease in Japan and hence a showing programme is used which involves a Ba repast x-ray followed by endoscopy.1.2 Stomach Cancer Incidence, Survival & A ; MortalityCancer is a cardinal wellness issue in the UK, where a one-fourth of all deceases are due to malignant neoplastic disease and one in three people develop malignant neoplastic disease at any point in their lives. Cancer is more common in older people where more than 75 % of deceases occur in people over 65, nevertheless it can develop at any age. The incidence rate of malignant neoplastic disease has increased by 20 % in males and 40 % in females since the mid-1970 ‘s ( 4 ) . Stomach malignant neoplastic disease was found to be the 9th most common malignant neoplastic disease amongst work forces and the 14th most common amongst adult females in the UK in 2008 ( 5 ) . Around 7610 new instances of tummy malignant neoplastic disease were diagnosed in the UK in 2008, 4923 instances among work forces and 2687 in adult females with an overall incident rate of 8.6 per 100,000 individuals. In Britain the incidence rates for both males and females have more than halved ; from about 30 per 100,000 in 1975-1977 to about 13 per 100,000 in 2006-2008 in males, and from about 14 per 100,000 in 1975-1977 to about 5 per 100,000 in 2006-2008 ( 5 ) . The rate increased quickly for people above 60 old ages to about 140 per 100,000 in work forces and 67 per 100,000 in adult females aged 85 and over in 2008 ( 5 ) . Survival from tummy malignant neoplastic disease progressively progressed in patients diagnosed in 1996-1999 compared to patients diagnosed in 1971-1975, peculiarly due to quicker and earlier sensing and diagnosing, and betterment in intervention ( 6 ) . In England and Wales ; the one twelvemonth endurance more than doubled in patients diagnosed in 1996-1999 compared to 1971-1975. The 5 twelvemonth endurance were about three times higher in patients diagnosed in 1996-1999 compared to patients diagnosed in 1971-1975 ( 6 ) . The mortality rate of tummy malignant neoplastic disease decreased by about 70 % in both males and females over the last 30 old ages in the UK. The tendency of mortality was similar to the tendency of incidence as the mortality rate was found to be higher in males than females across the UK in 2008 ( 7 ) . The different types of intervention for tummy malignant neoplastic disease include surgery, radiation therapy, chemotherapy and biological therapy. Combinations of the interventions are besides normally used such as chemotherapy and surgery in state of affairss where it is non possible to take a localized malignant neoplastic disease wholly as it has spread and hence chemotherapy is used to first shrivel the malignant neoplastic disease plenty to surgically take it ( 8 ) .1.3 Hazard FactorsMore than 70 % of all tummy malignant neoplastic disease instances are diagnosed in developing states ( 9 ) . Older people, males and people belonging to the most disadvantaged socio-economic position have a higher hazard of tummy malignant neoplastic disease ( 10 ) . Other hazard factors include ; smoke, intoxicant, weight, household history, exposure to radiation, business and Helicobacter Pylori ( 10 ) . Helicobacter Pylori is a bacterial infection that has higher prevalence in developing states and in people who have a low socio-economic position. In a survey of instances in 2010, it was found that 32 % of tummy malignant neoplastic disease instances were associated with infection of the bacteria. In other surveies it has besides been found that get rid ofing Helicobacter pylori may help in forestalling tummy malignant neoplastic disease ( 10 ) . There is uncertainness about the association of holding tummy malignant neoplastic disease and an unhealthy diet. A few surveies have found that a higher consumption of fruits and veggies is associated with cut downing the hazard of tummy malignant neoplastic disease, nevertheless other surveies such as the EPIC survey found that a Mediterranean diet reduces the hazard of tummy malignant neoplastic disease. Another survey found that pickled veggies increase the hazard of tummy malignant neoplastic disease in Nipponese and Koreans ( 10 ) . Family history of tummy malignant neoplastic disease increases the hazard of acquiring the disease, nevertheless some of this addition may be environmental, as some surveies showed grounds of increased hazard in partners of patients ( 10 ) . The EPIC survey found that physical activity reduced the hazard of tummy malignant neoplastic disease and have a protective consequence, nevertheless other surveies provide no grounds of such and hence farther research needs to be carried out to supply important grounds ( 10 ) .1.4 Socio-economic InequalityThe endurance between want classs varies well for tummy malignant neoplastic disease ; with flush patients holding higher endurance rates compared to strip patients as shown from a figure of surveies worldwide. Mitry et Al. ( 11 ) analysed tummy malignant neoplastic disease informations from England and Wales malignant neoplastic disease registers and found a statistically important ‘deprivation spread ‘ ( i.e. the difference in endurance between flush and disadvantaged categories of patients ) in survival analysis in work forces diagnosed between1986-1999. Another survey carried out in the Netherlands found that the hazard of deceasing was lower after seting for possib le confounders in flush patients compared to deprived patients ( 12 ) . A survey in Japan besides looked at the association between socio-economic position and tummy malignant neoplastic disease endurance by analyzing the endurance of patients by their business. There was grounds of disparity in endurance by business after seting for possible confounders and this was chiefly due to ulterior diagnosing of tummy malignant neoplastic disease amongst the lower businesss ( 13 ) . The want spread in endurance has widened for male patients diagnosed in the 1996-1999 compared to those diagnosed in 1986-1990. Mitry et Al. ( 11 ) showed that the want spread for both annual endurance and five-year endurance has widened steadily and significantly from 1986 to 1999 for tummy malignant neoplastic disease and that that the want spread in work forces is likely to go on broadening. In England There were grounds of socioeconomic inequality in tummy malignant neoplastic disease incidence, it was reported that incidence remained unchanged in the flush groups, nevertheless incidence decreased by 31 % in deprived work forces and by 47 % in disadvantaged adult females higher in West Midlands, England between 1986-2000 ( 14 ) . Many suggestions were put frontward to explicate the beginning of the want spread in malignant neoplastic disease endurance, and three chief factors were suggested ; phase of diagnosing, biological features of the malignant neoplastic disease, host factors and consequence of intervention, psychosocial factors, and intervention received, medical expertness and malignant neoplastic disease showing ( 15 ) .1.5 Aims & A ; AimsThe net ( comparative ) endurance in a population of malignant neoplastic disease patients is their endurance from the malignant neoplastic disease of involvement in the absence of other causes of decease. The comparing of net endurance in the UK by want class suggests a important broadening want spread in males ( 11 ) . The purpose of this undertaking is to look into whether the widening want spread in work forces was due to work forces in the deprived group non profiting from healing surgery. The phase at diagnosing will besides be studied to look into the possibility of deprived work forces diagnosed at a ulterior phase compared to affluent work forces. Datas from the eight regional malignant neoplastic disease Registries of England over the period 1997-2006 will be examined. This dataset will be linked to the Hospital Episode Statistics from which information on intervention will be derived, to analyze survival tendencies and estimate net endurance of patients with tummy malignant neoplastic disease after seting for sex, age, want spread, intervention and phase of disease at diagnosing. Net endurance will be estimated utilizing an extra jeopardy theoretical account. From the extra jeopardy theoretical account, all cause mortality will be modelled as the amount of the extra ( cancer-related ) mortality jeopardy and the expected ( background ) mortality. Net endurance will hence be calculated as the ratio of the observed ( all cause ) endurance to the expected ( background ) endurance. The background mortality/survival will be defined utilizing life tabular arraies from the general population. The life tabular arraies will be merged utilizing age, sex, twelvemonth of issue, GOR ( Government Office Regions ) and want class to the malignant neoplastic disease dataset. Net endurance by want class will foremost be estimated to find if there is any grounds of socio-economic inequality in malignant neoplastic disease endurance in the analysed period 1997-2006. An analysis will so be carried out, seting for confounders such as age, sex, intervention, and phase of malignant neoplastic disease.2 Materials and methodsThis chapter will supply description of the informations used in the undertaking and the statistical methods applied to predict net endurance from tummy malignant neoplastic disease by want category. The construct of flexible parametric patterning with restricted three-dimensional splines will be used to take into history differences in mortality by age, sex and intervention are discussed in item. All statistical analysis was carried out utilizing STATA 12.1 ( 16 ) .2.1 DatasThe UK is known to hold the most extensive/complete malignant neoplastic disease enrollment systems in the universe ( 17 ) . Presently there are eight malignant neoplastic disease registers in England. The malignant neoplastic disease registers in England collect information on clinical informations such as phase and type of malignant neoplastic disease, decease certifications which are forwarded by the Office of National Statistics ( ONS ) and demographic information such as day of the month of birth, day of the month of diagnosing, sex ( 18 ) . Information such as the malignant neoplastic disease class, phase and intervention are largely uncomplete. furthermore information on infirmary admittances and co-morbidity is frequently unavailable. Further information on malignant neoplastic disease patients can be obtained from the Hospital Episode Statistics ( HES ) . The HES is a database apparatus to include informations and information on all admittances in NHS infirmaries since 1989. Since 2003, the HES database has besides included and stored information on outpatients. The information in the HES are extracted from clinical instance notes. clinical instance notes include more elaborate descriptions of the clinical informations such as class and phase of malignant neoplastic disease at diagnosing, intervention received and co-morbidity. The malignant neoplastic disease register and HES database can be merged ( 19 ) utilizing the patients NHS figure and cardinal information day of the month of birth. Once the malignant neoplastic disease register and the HES database are combined, an independent cheque on the quality of the information is carried out every bit good as betterment in the completeness of the informations aggregation ( 19 ) . The patients acknowledged through decease certifications are followed up by their enrollment officers from their several regional malignant neoplastic disease registers to happen out the topographic point of intervention and therefore the patients ‘ infirmary & A ; instance notes. However this is non equal for some patients as they may non hold been provided any secondary attention ( hospitalization/clinics ) and therefore these patients are referred as decease certification merely ( DCO ) ( 20, 21 ) . Analysiss will be carried out on anon. informations from the eight malignant neoplastic disease registers in England on tummy malignant neoplastic disease diagnosed during 1997-2006. The patients identified suited for the analyses were merged in progress with their several patient records from the HES database from which information on intervention was extracted. Demographic information which included day of the month of birth, sex, Government Office Region ( GOR ) , day of the month of malignant neoplastic disease diagnosing and morphology were given for each patient. Information on the abode ZIP code at diagnosing and critical position ( dead, alive or emigrated ) were found from the Office of National Statistics for each patient. However as there was no information available the socio-economic position of each malignant neoplastic disease patient, utilizing the ZIP code ; the abode at diagnosing of each malignant neoplastic disease patients was identified and hence a want mark based on the abode was allocated to each patient. Five want classs ( from 1 ‘most affluent ‘ to 5 ‘most deprived ‘ ) were classified utilizing the income sphere mark of the 2004 Index of Multiple want ( IMD2004 ) and each patient was hence assigned to their several class based on their want mark. The IMD is based on everyday administrative informations of the 34,378 Lower Super-Output Areas ( LSOAs ) in England. Carstairs index ( 22 ) was the index used antecedently. Comparing the IMD mark to the Carstairs mark, the IMD is based on a smaller geographical country and is non based the nose count informations and therefore can be updated on a regular basis without transporting out a new nose count. The IMD is normally updated every 3-4 old ages.2.2 Statistical Methods2.2.1 Relative Survival and Excess MortalityNet endurance can be used to mensurate malignant neoplastic disease mortality straight. It can besides be used to mensurate extra mortality of malignant neoplastic disease patients compared to the general population. Net endurance can be estimated utilizing cause specific or extra mortality. Net endurance utilizing the cause-specific attack can be used by measuring the cause of each decease, merely the deceases attributed to the malignant neoplastic disease are considered and all other causes of deceases are censored. The major disadvantage is that there is a strong dependance on the quality of decease records. Cause-specific endurance can be used to mensurate malignant neoplastic disease mortality straight and uses inside informations of all deceases, nevertheless the cause of decease in this instance is malignant neoplastic disease and is used in the malignant neoplastic disease mortality. This method requires the cause of decease to be accurate and exactly specified, nevertheless the cause of decease is non given in most instances. Indirect deceases such as deceases due to route accidents or deceases due to side-effects of medications/treatment alongside deceases due to malignant neoplastic disease are hard to sort. Furthermore, different diagnosticians will specify cause of decease otherwise depending on the state of affairs at clip of decease hence cause of decease may non be right defined. There are two methods of appraisal of the cause specific attack are Kaplan-Meier method and the Acturial method. Excess mortality is a method which accounts for malignant neoplastic disease mortality straight and indirectly without necessitating an accurate and precise specification of the cause of decease ( 23 ) . The extra mortality is derived as the difference in the ascertained mortality ( mortality due to all causes ) and expected mortality ( mortality due to non-cancer-related causes ) . Both extra mortality methods estimation malignant neoplastic disease mortality after seting for background mortality from assorted other causes and hence presumptively should give similar values. In world nevertheless this depends on how suitably premises are fulfilled for each several method, chiefly accurately documenting and stipulating the cause of decease for the cause-specific method and the truth of gauging the expected mortality for the extra mortality method ( 23 ) . Excess mortality is classified mathematically utilizing the jeopardy map at clip since diagnosing as. The jeopardy map is equal to the amount of the extra jeopardy due to stomach malignant neoplastic disease diagnosing and the expected jeopardy ( sometimes known as the baseline jeopardy, estimated utilizing external informations from the general population ) where is the covariates vector ( 24 ) . Equation ( 1 ) Net endurance ( Relative endurance ) is the survival corresponding to extra mortality, and is derived as the ratio of the ascertained endurance of the malignant neoplastic disease patients to the expected endurance estimated from the general population utilizing life tabular arraies. Equation ( 1 ) may therefore equivalently be written in footings of net/relative endurance as Equation ( 2 ) where and are the cumulative observed and expected endurance severally. The relation between the jeopardy map and expected jeopardy and cumulative observed and expected endurance severally, is given by and, and the net/relative endurance is so given as. ( 24 ) The jeopardy is assumed to be piecewise changeless over of follow-up clip ( changeless over little clip intervals ) in pattern and hence a short period such as a twelvemonth or less might be used at the start of the followup. If a longer period is used so the changeless jeopardy premise is violated and clip since diagnosing is non automatically adjusted for and is hence the uninterrupted map may be modelled as a measure map. A new covariate vector is derived by adding the covariate vector with the index variables where the index variables are generated for all intervals apart from the mention interval. A multiplicative map of the covariates in the signifier of is assumed to be the extra jeopardy and therefore equation ( 1 ) becomes Equation ( 3 ) or instead Equation ( 4 ) where the parametric quantity estimates when exponentiated can be inferred as extra jeopardy ratios ( EHRs ) . The jeopardies are assumed to be relative implicitly in equation ( 3 ) . By Introducing interaction footings of the follow-up clip and covariates in the theoretical account can be used for patterning non-proportional jeopardies. Excess mortality can be estimated utilizing assorted different methods, Different methods exist for gauging extra mortality, either utilizing a full likeliness attack ( 25 ) , or based on sorted informations incorporating one observation for each life table interval within a generalised additive theoretical account ( 25, 26 ) . Life tabular arraies provide information on endurance and give the chance of decease in the general population stratified by age, calendar twelvemonth, sex, want and authorities office part ( GOR ) . The life tabular arraies in England are based on the nose count informations and are hence updated every 10 old ages to demo alterations in life anticipation. In the analysis carried out for this undertaking the life tabular array used is stratified by sex, age, GOR, twelvemonth of issue, and IMD quintile. The Life tabular arraies from 1981-2010 were used. Life tabular arraies are based on mortality in the general population, which include the mortality due to stomach malignant neoplastic disease, but because decease due to malignant neoplastic disease is little compared to the general population, it does non impact net/relative endurance estimations in pattern Ederee et Al. ( 27 ) . The stpm2 bid in STATA was used to foretell comparative endurance. The timescale and failure were declared utilizing the stset bid, and the clip beginning for the analysis was taken to be the day of the month of diagnosing of each topic. The timescale was calculated in old ages and the extra mortality was modelled as the primary result of involvement as suggested in ( 23 ) .2.2.2 SplinesFrequently complex non-linear effects from uninterrupted variables e.g. age are modelled in arrested development theoretical accounts. There are many improved methods of patterning complex and non-linear effects. Splines is an easy manner of including an explanatory variable in a smooth non-linear manner. Mathematical maps which are sections of multinomials and joined together at points called knots are known as splines. To do the spline smooth, A figure of restraints which include limitations on the mathematical derived functions of the spline map are applied between next multinomial sections so that the curve is smooth at the knot. In general, splines can be generated utilizing multinomials of any grade. However three-dimensional splines are frequently used, in which each section can be written as a three-dimensional multinomial as three-dimensional multinomials normally model most curves right and are computationally easy to obtain. The smoothness status for a three-dimensional spline means that the spline map is uninterrupted i.e. the first and 2nd derived functions are uninterrupted everyplace and there are no leaps or interruptions in the spline. A three-dimensional spline with K knots may be derived mathematically in footings of K+4 parametric quantities in general as ( 28 ) : where the notation classifies the incline map, where if, and if and the knots are at places severally. Cubic splines behave ill at the dress suits when fitted to informations is less and the spline map may be susceptible to extreme value. A subset of three-dimensional splines where the spline map is additive before the first knot and after the last knot are known as restricted splines ( 28 ) . A restricted three-dimensional spline can be specified by K-1 parametric quantities for K figure of knots which is 5 less than a general three-dimensional spline. where the is defined as: With a logarithmically transformed clip variable, restricted splines are normally used to pattern the extra jeopardy. Knots can be anyplace on the log-outcome clip distribution, where the boundary knots at the first and last log-outcome clip.2.2.3 Flexible Parametric Survival ModelsRoyston and Parmar ( 29 ) foremost introduced flexible parametric theoretical accounts in the position of censored endurance informations. This method of patterning informations gave more flexibleness to the form of the jeopardy map in comparing to other parametric theoretical accounts e.g. the Weibull theoretical account for which the signifiers of the jeopardy map are limited. The flexible parametric theoretical accounts do non necessitate numerical incorporation and hence a cardinal advantage of such theoretical accounts is comparatively fast calculations. ( 30 ) The Cox theoretical account is the most common method of covering with censored informations, nevertheless flexible parametric theoretical accounts can cover with non-proportional jeopardies more expeditiously. In flexible parametric endurance theoretical accounts, clip is treated as a uninterrupted variable and hence unlike piecewise approaches the demand of dividing the time-scale is non needed ( 24, 26 ) . The big Numberss of excess parametric quantities which are required to be created so that time-dependent effects are incorporated in the piecewise attack are hence non required in this modeling attack and hence this reduces the computational clip and uses less computing machine memory particularly for big datasets. Alteration of the flexible parametric theoretical accounts have since been done for comparative endurance theoretical accounts ( 30, 31 ) A parametric theoretical account is defined as a theoretical account which can be identified in footings of a fixed set of parametric quantities ( , , †¦ ) . Restricted three-dimensional splines are fitted to the estimations of the log baseline jeopardy in a flexible parametric net/relative endurance theoretical account ( 30 ) . Equation ( 6 ) Transforming to the endurance graduated table Equation ( 7 ) where is the restricted three-dimensional spline map of with knots, and is the cumulative overall jeopardy. The log-likelihood map is obtained utilizing equation ( 6 ) and numerical methods are used to gauge the parametric quantities which give upper limit likeliness utilizing equation. Thus the endurance and hazard maps can be analytically estimated.2.2.4 Evitable DeathsA manner of infering extra hazard ratios is by ciphering evitable deceases ( 32-34 ) . The figure of evitable deceases is the figure of deceases due to stomach malignant neoplastic disease which could be avoided if the net endurance in all socio-economic classs would be the same as that of the most flush class after seting for the different features of each class. The expected figure of deceases due to all causes amongst a specific group of patients utilizing equation ( 2 ) is: where N is the size of the population, is the expected endurance at clip T and is the net endurance of the concerned group at clip T. In the general population, the predicted figure of all-cause deceases in a matched group is:.The premise of net endurance being the same as in a population being compared to is made ( in this instance the least disadvantaged ( flush ) category ) to deduce evitable deceases. The figure of evitable deceases are calculated by deducting the predicted figure of deceases due to all causes given the new comparative endurance from the predicted figure of deceases due to all causes given the original comparative endurance. The figure of â€Å" evitable † deceases represents postponed deceases which will happen subsequently and hence are really variable with the follow-up clip.2.3 Statistical AnalysisTo transport out the statistical analysis, informations were examined to vouch it ‘s dependability. Consistency cheques were besides carried to do certain informations was placed in the needed scopes. Datas from the Hospital Episode Statistics ( HES ) database were merged with the malignant neoplastic disease register informations, and information on intervention was obtained. patients whose records could non be matched to the HES database were excluded. Patients who had losing informations on variables such as GOR or IMD mark ( used to deduce want classs ) , which were used in unifying with the general population life tabular array to gauge the net endurance were besides excluded from the analysis. The patient distributions were examined by the chief explanatory variables on the information. To happen differences in want class, cross-tabulations of other variables ( such as intervention, GOR and malignant neoplastic disease registers etc. ) by want category were carried out. Net endurance by want category was estimated utilizing a flexible parametric theoretical account. This theoretical account did non affect any variables with losing informations and the stpm2 bid in STATA was used to cipher predicted net endurance. Expected chances of decease were estimated by unifying the life tabular arraies stratified by age, sex, want and GOR and twelvemonth of issue, to the malignant neoplastic disease dataset ( formed of HES merged with the malignant neoplastic disease register informations ) . The method of flexible parametric theoretical accounts utilizing restricted three-dimensional splines was used, as this method was computationally less ambitious and less clip consuming and a more accurate method of analysis. Using flexible parametric patterning with splines, interaction footings were fitted in the theoretical account. As extra mortality was predicted to differ non-linearly with age, hence interaction footings for age with splines were besides introduced. To prove the rightness of this method of analysis, both in footings of the procedure of utilizing splines and besides presenting the interaction footings of the theoretical account. Net endurance for up to 10 old ages was estimated and predicted by want category, seting for sex, intervention and age group. A new variable dividing the age with 5 splines was so created and used to do dummy variables for the restricted three-dimensional age splines variables. A restricted three-dimensional spline with 5 knots was used. To let for non-proportionality in the extra jeopardy for both twelvemonth ( twelvemonth of diagnosing ) spline and age spline variables, dummy variables for the interaction between both variables were generated. A figure of flexible parametric theoretical accounts were fitted for males and females individually. The first theoretical account was fitted with want and chief confounders such as the age splines and twelvemonth ( twelvemonth of diagnosing ) splines. A 2nd theoretical account with interactions between age splines and twelvemonth ( twelvemonth of diagnosing ) splines every bit good as utilizing all the variables from the first theoretical account. The 3rd theoretical account was fitted by including intervention ( as the association between intervention and want class was to be examined particularly in patients who had surgery ) in the best adjustment theoretical account out of the first two theoretical accounts. The theoretical accounts were re-fitted with clip changing effects with age merely and so with both age and clip of diagnosing. These theoretical accounts were compared for the best of tantrum utilizing the likeliness ratio trial. To happen out which grades of freedom ( DF ) for the baseline jeopardy produced the better adjustment theoretical account, the best adjustment theoretical account without the clip changing effects was fitted with 1 to 5 DF and so compared utilizing Akaike information standard ( AIC ) and Bayesian information standard ( BIC ) . The best fitting theoretical account with the DF for the baseline jeopardy was chosen to be the 1 with the smallest AIC and BIC. The same method was used to make up one's mind which DF for the varying effects was best used for the best fitting clip changing effects theoretical account. The scrutiny of evitable deceases was carried out to gauge and foretell the figure of evitable deceases at 1 and 5 old ages if endurance was the same in all want classs as the most flush class.3 Consequences3.1 Description of the malignant neoplastic disease register informationsFor the analyses to be carried out, a sum of 70,370 patients who were diagnosed with tummy malignant neoplastic disease during the period of 1997-2006, and were linked to the HES database. From the entire figure of patients, 1729 ( 2.46 % ) patients were registered via their decease certification merely ( DCO ) or had zero endurance ( day of the month of decease was the same as the day of the month of diagnosing ) . Zero endurances were included in the analysis by adding one twenty-four hours to the day of the month of decease, as excepting them would overrate the endurance, nevertheless it is known that DCOs seldom have a confirmed day of the month of diagnosing ( 21 ) . Of the entire figure of tummy malignant neoplastic disease patients, 45,580 ( 64.77 % ) were work forces and 24,790 ( 35.23 % ) of the patients were adult females. Table shows the figure of tummy malignant neoplastic disease instances by GOR. The largest absolute figure of tummy malignant neoplastic disease patients was in the North-West part and the smallest being in the North East part. Table: Proportion of tummy malignant neoplastic disease patients by Government Office Region Government office part Number ( % ) of patients North East ( A ) 5,157 ( 7.33 ) North West ( B ) 11,615 ( 16.51 ) Yorkshire and The Humber ( D ) 8,710 ( 12.38 ) East Midlands ( E ) 6,278 ( 8.92 ) West Midlands ( F ) 8,461 ( 12.02 ) East of England ( G ) 7,027 ( 9.99 ) London ( H ) 7,508 ( 10.67 ) South East ( J ) 8,878 ( 12.62 ) South West ( K ) 6,736 ( 9.57 ) The proportion of males to females and average age of tummy malignant neoplastic disease diagnosing were similar across all want categories, the highest mean age at diagnosing in the in-between want class ( 73.3 old ages ) and the lowest amongst the most disadvantaged group and the flush group ( 72.4 old ages ) , nevertheless this difference in mean age at diagnosing was non that large amongst want categories. The spread for age amongst all want categories was found to be similar due to the lopsidedness and standard divergence. The proportions of topics coming from each GOR by want category differed mostly. Figure: Percentage of patients by want categoryA clear monotonically increasing form was found in the per centum of people by want category, where there was a lower per centum of patients from the flush category and a higher per centum of patients from the disadvantaged category as shown in Figure 1. Figure: Percentage of patients having no intervention A tendency was seen in intervention. Figure 2 shows that the most disadvantaged group were less likely to have any signifier of intervention. The tendency in the per centum of patients having any intervention including surgery was found to back up the consequences from Figure 2, where the per centum of patients from flush to the most disadvantaged were 34.63 % , 34.30 % , 33.74 % , 33.02 % and 32.79 % severally.

The distribution of the proportion of males and females was similar for all want, intervention, GOR and malignant neoplastic disease register classs. The proportion of males was about twice every bit many as females for site C160 and the proportion of females was more compared to males for site C169, nevertheless the proportion of males and females were similar for all other sites. A important factor in finding endurance is intervention, hence a trial was carried out to see if there was any difference between want classs in the proportion having any intervention compared to those non having intervention, and in the proportion having intervention affecting surgery compared to those undergoing no surgical intervention. Two logistic arrested development theoretical accounts were hence carried out, one for the proportion having any intervention and the other for the proportion having surgical intervention by want class, seting for age and twelvemonth of diagnosing, individually for males and females. After seting for confounder, the odds of acquiring any intervention for females in the most disadvantaged class were 0.88 times less than in the flush class ( p-value 0.009 ) . There was no difference in the odds of intervention in males between want classs. After seting for confounders, the odds having surgical intervention in males from the more disadvantaged classs was 1.18 times more than in the flush class ( p-value & lt ; 0.001 ) and no difference in the odds of having surgical intervention in females between want classs. The average age at diagnosing was 72.92 old ages. The mean overall follow-up clip of 1.57 old ages as shown in table 3. The per centum of patients who died by the terminal of the follow-up period was found to be 91.64 % of patients. Table 3 shows the average follow-up clip ( the norm clip until stomach malignant neoplastic disease patients are dead or censored ) and the per centum of those who died stratified by age group, want category and intervention. A really little difference was found in both overall mean follow-up clip and the proportion dead by the terminal of followup between males and females. The average follow-up clip was longer and the proportion of patients deceasing by the terminal of the followup was lower in younger topics. The average follow-up clip was longer and the proportion of patients deceasing was lower in the patients belonging to the most flush class, with both results demoing an diminishing tendency by diminishing want category. The average follow-up clip of patients having surgery, with either or both radiation therapy and chemotherapy, was longer than those patients who did non have surgery and the proportion death by the terminal of followup was smaller. This was chiefly due to the fact that chemotherapy and radiation therapy interventions were carried out on patients at the ulterior phases of the malignant neoplastic disease, whereas surgery was carried out earlier phase, nevertheless this may propose that patients who underwent surgery had a better endurance.

The grades of freedom for the baseline jeopardy were chosen utilizing the AIC and BIC consequences from Table 4. Table 4: Degrees of freedom for Baseline jeopardy and their AIC/BIC Baseline Hazard DF Model DF AIC BIC Male 1 16 92327.50 92467.13 2 17 87329.59 87477.95 3 18 86419.88 86576.97 4 19 86097.21 86263.03 5 20 85890.83 86065.38 Female 1 16 44135.45 44265.34 2 17 41201.07 41339.08 3 18 40783.54 40929.67 4 19 40686.45 40840.69 5 20 40568.31 40730.67 From Table 4, it can clearly be seen that the theoretical accounts fitted with 5 grades of freedom for the baseline jeopardy give the smallest AIC and BIC for both males and females and hence provide a better tantrum for the theoretical account. Although it seems best to utilize 5 DF for the baseline jeopardy, 3 DF will be used as the theoretical accounts with 5 DF are computationally intensive when clip changing effects are included.

Between the five want groups, 1-year predicted net endurance ranged from 0.32 to 0.36 for males and 0.33 to 0.38 for females. The 5-year predicted net endurance ranged from 0.12 to 0.16 for males and 0.15 to 0.19 in females. The 10- twelvemonth predicted net endurance ranged from 0.09 and 0.12 for males and 0.11 to 0.15 for females ( Table 5 ) . In general, the predicted cyberspace endurance scope had a somewhat higher lower limit and upper limit for females than males bespeaking that the predicted cyberspace endurance was overall better/higher in females than males. The estimated difference in endurance was 0.04 in males and 0.05 in females between the most flush and the most disadvantaged groups at one twelvemonth after diagnosing. At five old ages after diagnosing the estimated difference in endurance between the two groups was the same for males but decreased to 0.04 for females. A clear additive tendency was seen between one and five old ages after diagnosing. The tendency between the least disadvantaged and most disadvantaged classs remained up to ten old ages after diagnosing, although at ten old ages the endurance of the two most disadvantaged classs was the same.

Comparing the consequences of males and females, the extra jeopardy ratio ( EHR ) of decease by want class was higher in general for females, although both analyses gave a additive tendency in EHR by want. For both males and females, the EHR of decease by want was statistically important indicating that the EHR differed for each want class compared to the most flush class. Therefore more disadvantaged groups had a higher extra mortality due to malignant neoplastic disease compared to the less disadvantaged groups. Age and twelvemonth of diagnosing were modelled as a non-linear effects, and were important in for the first three age splines for both males and females and were important for twelvemonth spline 1 and 4 in males and twelvemonth splines 1 & A ; 2 in females.

The grades of freedom for the baseline jeopardy were chosen utilizing the AIC and BIC consequences from Table 4. From Table 7, it can clearly be seen that the theoretical account fitted for males with 5 DF for the clip variable consequence gives the smallest AIC and BIC, nevertheless the theoretical account fitted for females with 4 DF has the smallest AIC and BIC. Therefore either 4 DF or 5 DF can be used run the analysis for the clip changing effects and intervention. Further analysis was carried out utilizing 4 DF.

Comparing the consequences from the male analysis with the female, the extra jeopardy ratio ( EHR ) for decease by want was lower in females in general, although both analyses gave a additive tendency in EHR by want. Comparing the EHR for both analyses to consequences from Table 6, it is clear that the EHR is lower when intervention and clip changing effects such as age and twelvemonth of diagnosing are taken into history. There was besides lessening in EHR for any intervention compared to no intervention ; nevertheless there was a big lessening in EHR of surgery compared to no surgery for both males and females. In both analyses, intervention with surgery was associated with increased net endurance compared to non-surgical intervention or no intervention. Age and twelvemonth of diagnosing were modelled as a time-dependent non-linear consequence, and were important for peculiar splines in both theoretical accounts. The additive tendency in want category remained and became more important, since the EHR in want classs for both males and females differed in comparing to the most flush group at the 5 % significance degree, as in the instance of the simpler analyses. Therefore more disadvantaged groups had a higher extra mortality due to malignant neoplastic disease compared to the less disadvantaged groups. The deficiency of an interaction term between want classs and splines in the concluding theoretical account suggests that the difference in comparative endurance between want groups did non alteration over the clip period of the survey.

Before the discovery of Australia, all the world had never seen a black swan before. An impossible accomplishment in someones life before this time was referred to as â€Å" a black swan.† The mere sight of one black swan after the discovery of Australia negated the thousands of years of sightings of white swans and thinking they were the only species of swan. This generalization that was put on the term â€Å"black swan† before the british occupation of Australia is just an example of the illustration of the human mind and how one sighting can alter the mindset of thousands of years of thinking. The author Nassim Taleb has donated his whole life to philosophy, uncertainty, probability and finance. Starting as a chauffeur, Nassim worked his way up to become a businessman trader and later a university professor. By using his theory of Mediocristan and Extremistan, Taleb explains how the impact of the highly improbable affects all of us and personally each person has a handful of â€Å"black swans† which alter our lives for the better , or the worse. Mediocristan are easy to predict events that are easy to mentally compute, while extremistan are events that are unpredictable and affect the world in a major way. The Black Swan by Nassim Taleb is a nonfiction philosophy book that expresses one mans theory on rare human events that happen without warning, yet greatly impact the world as we know it. This book can be seen as a memoir of Taleb’s life and how his research has been his black swan, and has driven him to take risks and go greater distances than he would have without the incentive. The purpose of this book is to inform the reader of the impact of the highly unpredictable. A black swan , in terms of an event has 3 properties, 1. It is hard to predict based on historical information, 2. Low predictability – High consequence , 3. The events are perspectively unpredictable yet retrospectively predictable. The black swan events happen in everyones lives, or at least â€Å"affect† everyone lives. For example one of the most famous black swans in recent history is the invention of the computer and world wide web. Originally seen as a stock bubble by intel, is now a multi trillion dollar industry and a large part of the world are in contact with it. The book embarks on many peoples journeys and encounters with black swans, all encounters were unexpected but altered the peoples lives in a major way. The book takes place in Lebanon but mostly New York, where ironically many of the black swans happen. Having to do with different mathematical formulas, Taleb’s book hits the major focal points of rare events and that everyone encounters them making all people black swans in there own way. This book should be read by anyone interested in philosophy or the stock market. Although people don’t see it this way, but the stock market is directly affected by black swans and such things mentioned in the book as Gaussin’s bell curve or mediocristan and extremistan. These formulas and theory’s affect the market and affect the life of people. This book was very interesting and after reading it, the reader gets a different view on life and how major events in there life time, ex. ( 9/11, invention of the computer†¦) affect there life and impact there day to day progress as a human being.

How did reform movements from 1815 to 1850 change America? Essay

Reform movements from 1815 to 1850 tried to change America. Women’s rights movements, education movements, and thoughts of abolition were main inspirations. Women’s rights movements were becoming more common. More women than ever were coming together to protest. The Seneca Falls Convention was the first organized women’s rights movement. When women went to other conventions they were excluded, this convention was about women and for women. These conventions would eventually persuade congress to pass a law allowing women to vote in the 1900’s. Education movements were also a common thing among minorities. Young Americans in general along with women, African-Americans, and disabled people wanted the educational system improved. A common school movement was started to improve the quality of public schools and help prepare students for success. African Americans wanted schools to allow them in and to supply an education equal to that of young white males. Before the 1820’s women could not obtain a worthwhile education. Catherine Beecher helped the campaign for women’s education. Disabled people were not educated either. Samuel Howe improved the school system by developing methods for teaching the visually impaired. Among other impairments this was the most important to people of this time. After these movements the quality of education was not just a dream. Education changed dramatically during this period, the system went form only white males able to obtain an education to practically any person being able to. Abolition was probably the most important movement of this time. Slavery was becoming a great issue in the government and among commoners. Many of the abolitionists supported the idea of freeing the slaves but not the equality of the African American man. The fight for the outlawing of slavery became so great that the Underground Railroad and other escapes were created. Slavery was eventually outlawed by congress because fights were breaking out. Today most Americans look back and do not understand how this was even an issue. America has become a country against slavery because of the proceedings of this time era’s fight for abolition. These three movements, women’s rights, education, and abolition, were the most important influences on America today. They did not only try to change America but they succeeded. Women have equal rights with men, education is open to any being white, African American, or disabled, and slavery is outlawed.

Change Management in Delta Airlines Research Paper

Change Management in Delta Airlines - Research Paper Example The next portion of the project would be dealing with the diagnosis of the business conditions of Delta Airlines. This part would be discussing the mission and vision statement of the company followed by its objectives and business strategies. The third part of the project would reflect change management within the organization by an implementation of Kotter’s eight-step approach. The Eight Step Model of Kotter is one of the most popular models for scheduling, implementing and finally sustaining a change process. Company Overview As already discussed above, Delta Airlines is a popular American Airline whose headquarter is located in Atlanta, United States (Federal Aviation Administration, 2013). This airline generally operates both international and domestic networks having its service routes in all the continents excepting Antarctica. The company along with its subsidiaries operates more than 5000 flights regularly. The company employs 80000 employees approximately (Delta Air lines, n.d.). The hub is located at Hartsfield Jackson Atlanta International Airport, which is one of the busiest airports in the world, in terms of passenger traffic as well as the total number of takeoffs and landings. It is the sixth oldest international airline because of its foundation date. Moreover, it is one of the oldest airways in United States as well. The company is one among the 4 founding members of Sky Team Airline Alliance, the other 3 being Air France, Aeromexico and Korean Air. The company has been declared as the largest airline in the world in 2011and 2012 in terms of the total fleet size and the scheduled passenger traffic (Rediff, 2013). It has also been rewarded for becoming the second largest airline in respect of the total revenue-passenger kilometers carried in the year 2012. The Delta Connection provides regional service to the company. Diagnosis The foundation of the company is based on the reliable and safe air transportation, providing differentiated cu stomer service to the travelers or passengers. Delta Airlines leads in the airline industry for providing the best airline transportation. The company entered into the industry in the year 2013 by further strengthening its business strategies. It is continuing to improve the performance by executing strategic initiatives. While many of the competitors of the company were focusing on the restructuring efforts or the significant integration, Delta Airline undertook the strategy of advancing its market position across the globe. The innovative business strategies of Delta Airlines (including the re-branding technique) have helped the company in strengthening its position in the world. The acquisition of Northwest Airlines proved to be one of the successful business strategies for the company. This strategy helped the company in reshaping the business goals. In past few years, the company has taken various steps in improving its balance sheet, expanding its operations by getting into gl obal partnership, investment in airlines, such as Virgin Atlantic and finally purchasing oil refinery. It increased its flexibility in these two years in order to reduce its flaws and strengthen the market reputation. However, the launch of the company’s song as a low cost airline followed by its ‘codeshare agreement’ with the Northwest Airlines and the Continental Airlines initiated the declining phase of Delta Airways.  Ã‚  

Proposal Background and Problem Statement Research Paper

Proposal Background and Problem Statement - Research Paper Example The practice is also suspected in the technology industry where manufacturers are suspected of producing all forms of viruses and harmful programs only to produce anti-viruses to be bought and used in treating the problems caused by the viruses. In the pharmaceutical industry, the phenomenon is referred to as disease mongering. This research shall look into various ways through which diseases are intentionally or unintentionally transfer from pharmacists and other health practitioners to patients and later taken advantage of because of the need for patients to seek cure to these diseases. Aims and Objectives This research proposal has an aim of identifying the relationship that exists between the drug manufacturing companies and diseases. To achieve this, the following specific objectives have been set. 1. To find out some of the intentional and unintentional ways through which diseases are manufactured in the laboratory. 2. To establish how disease hyping has been used as a trade st rategy for the sale of medicines. 3. To find the place of federal laws in fighting against any unfair deals associated with disease mongering. 4. To ascertain whether people are being made to invest excessively more on their health than their health risk actually demands. Significance of the Study The completion of this study is of significant important to a multi-dimensional group of persons. In the first place, the pharmaceutical industry shall be made aware of some of their practices that lead to the spread and outbreak of diseases and how these can be contained. Again, the public shall be educated on some of the unacceptable means by which the pharmaceutical industry extorts their monies and thus the need to be highly mindful of their health budgets, especially towards promoted diseases. Finally, this research shall seek to protect human health against some common health sector practices such as the exposure to radiations and administration of certain medicines that go long ways to affect the health of people. Research Questions 1. In what ways does the pharmaceutical industry use corruptible means to extort monies from the public through the manufacture of diseases? 2. Are there laws that check the occurrence of disease mongering in our society? 3. Is there enough education for the public on how to guard themselves against practices of the health sector that promote diseases? 4. In what ways can the public different between a genuine campaign against diseases and one that only seeks to hype diseases for selfish gains? Limitations This research shall face a number of limitations in its conduct. For instance the pharmaceutical industry, which is under scrutiny here, may not be very willing to be co-operative with the researchers in finding facts and data on the problem of disease mongering. This is highly anticipated as the research seeks to expose certain corrupt practices associated with disease mongering. The researchers also face a limitation of carryin g out the most rightly prescribed information to the general public. This point is made against the backdrop that readers may be ill-informed to assume that all forms of medical campaigns against diseases constitute disease mongering and so they must always brush such campaigns aside. If this happens, the aim of the research will be defeated because the research seek

Negative impact of globalization Essay Example | Topics and Well Written Essays - 500 words

Negative impact of globalization - Essay Example The line of living standard between rich and poor is accelerating alarming rates. Organizations like World Bank and IMF, for instance, provide huge loans and funding for projects primarily aimed at obliging the Neoliberal politics of globalization. The formation of an unrestricted international free market has benefited multinational companies and corporations in influencing the political decisions. These corporations are continuously deriving huge benefits at the expense of local enterprises, cultures, and people, mostly in the western world. Privatization of national holdings has led to job insecurity and lower standards of living. Employees are being recruited on contract basis reducing job incentives. A lot of people are even working at less than minimum wages due to far greater job competition that has affected their normal living standard adversely. Additionally, employees are living in a constant fear of losing their jobs to competition. Developed countries worldwide have strong standards for pollution control. Firms take advantage of the countries with poor environmental regulations and are continuously setting up industries degrading the environment for financial gains. The popular fast food chains such as McDonalds and KFC are attracting more people to consume junk food giving rise to various health concerns. Businesses in developed countries are outsourcing jobs to cheaper developing world consequently leaving their own people with less job opportunities. For instance, the cost of manufacturing goods and wages are low in China and India. Many local talents like programmers, writers, scientists, accountants and teachers have lost their jobs as a result of outsourcing to these countries. One of the major adverse effects of globalization is child labor exploitation. Child workers are recruited at comparatively negligible cost and are

Database Systems Concepts Essay Example | Topics and Well Written Essays - 750 words - 2

Database Systems Concepts - Essay Example In addition, RAM is usually much smaller in size, about two to three orders of magnitude being frequent. (A rig that I know of has 8 Gigs of RAM and 2 terabytes of hard drive space, and the owner has room to expand to over 5 terabytes, which is roughly a three order of magnitude difference). Scheduling is almost entirely unnecessary. There is a need to compare the RAM disk and the main memory disk-cache, but this doesn't affect the choice of a scheduling algorithm for the hard drive because they are totally different systems and because scheduling on the RAM disk is only looking for buffer cache misses not main memory requests. Hard-disk scheduling considerations are totally different. Hard disks are much larger and they are not read constantly, and the head positioning must jump in order to handle different reads. The file system does store recently used blocks in a buffer cache in main memory, but this is only a partial time-saving maneuver. Caches have finite sizes and need to be purged constantly; in any respect, no one sticks to only a few things in cache. They are constantly opening up new pages, documents and programs, which requires accessing different parts of the disk. This means that scheduling for hard-disk use is at a premium: Indeed, one of the main slowing forces in Moore's Law exponentiation is the relatively anemic growth of hard-drive scanning speeds versus the memory size of hard drives. Different hard disk scheduling regimes have different benefits. When designing a scheduling algorithm, it is important to bear in mind parameters of functionality. These include power consumption, throughput, response time, flexibility for the end-user, and other factors. Again, the cache can only do so much in mitigating these problems, so the choice of how to approach hard disk scheduling has many inherent tradeoffs. One approach is FCFS, or First Come First Served. In this algorithm, operations are conducted in the order requested. This is very simple and elegant in many ways. However, the problem is that not all functions are made equal: Some functions, like Ctrl-Alt-Delete on a Windows computer or dealing with security threats, need to be scanned first. FCFS therefore doesn't have the costs of reordering the work queue, but it doesn't have the benefits either. FCFS cannot have starvation: Every request is serviced. But the performance is poor: It doesn't distinguish between the importance of needs, nor does it have any smart geography. If a end user wants to run six programs from every different side of the disk, FCFS will go in order, crossing immense redundant space and thus leading to slowdown. SSTF, on the other hand, prioritizes geography of the desk. It goes to the closest location on the disk first, no matter what. Again, this has the problem that there is no discrimination for important tasks. Scan time is reduced, but starvation is possible: The head could stay in one sector of the disk for too long if too many requests co me in. Direction switches also slow things down. SCAN goes from the outside to inside then the inside to outside. This has the advantage of being a uniform pattern and reducing variance, but it does lead to a lot of unnecessary scans (though not more scan time) which can be a power consumption issue. LOOK is a bit smarter: It stops going a direction where no requests exist. C-SCAN and C-LOOK use cylinders instead of a simple directional approach. This has the adv

Learning Journals Essay Example | Topics and Well Written Essays - 750 words

Learning Journals - Essay Example On an organization perspective, a company comprises of critical parts that one would regard as the brain such as upper management and CEO’s (Buono & David 120). Additionally, these individuals are responsible for sending information to all other sections of a company in the same way the brain transmits information. Moreover, this process requires open communication lines to enhance effectiveness since these individuals inform others on the preferred mode of operation to enhance productivity. The brain comprises of two sides namely logical and creative (Buono & David 122). Apparently, organizations comprises of these sides too. They need to be logical to perform daily operations. Moreover, they need creativity to develop novel products or modernize existing commodities. If one views the negative components of an organization using the brain metaphor, an organization tends to lose focus. This mainly occurs to companies that have not established a strategic plan. Furthermore, the se organizations tend to forget their target goals. It is not appropriate to compare an organization with a brain in this case. The main negative comparison is apparent when the brain does not converse with others parts though this may occur in an organization. Employees fail to converse among themselves causing trouble within the organization. A prime advantage of this metaphor is that it recognizes the necessities of learning institutions in a comprehensive manner. Furthermore, it also recognizes how diverse components need to complement each other. A majority of management writers have performed an excellent job in recognizing the requirements of the learning process that are necessary in making learning a reality. Therefore, the strength of this metaphor is evident in its ability to bring such components together and reveal the best approach to progress (Rhodes 1). An organization’s belief and rituals identifies culture. After investigating design Inc culture, one can see how the beliefs of the founder influenced corporate culture. An organization comprises of a culture, set by management to function in a definite method and to a particular motto (Pfister 122). Therefore, Brown developed a culture of perfection in design Inc. The basis of this culture was brown’s philosophy that attainment of work satisfaction is through meeting the perfection standards as opposed to finical reward. Moreover, this standard of perfection and development within the organization allowed Brown to trade this cultural norm to individuals wishing to join the organization. He could not provide luxuries and frills offered by different companies but provided perfection and fulfillment (Pfister 124). Therefore, one can translate that the philosophy in design Inc is the belief in excellence, founded on brown’s motto of ‘Perfection or bust’. In this study, one can see the integral role executed by a leader in a culture. This determines the values that direct an organization. Brown dreamt of establishing an organization that would be different from other companies. He often said that he does not offer jobs to people but instead provides a distinctive learning experience. Morgan suggested another metaphor that views an organization as a political system. It is simple to understand how this metaphor relates to diverse organizations. Managers occasionally indicate that authority is the basis of their association with their

Human Resource Management & Information Management (MBA) pro 4 Essay

Human Resource Management & Information Management (MBA) pro 4 - Essay Example The company has to align its business to n effective IS response giving it significant ground in the market. The IS that Brady Corporation was currently operating on did not support its business model since it made use of antique systems that were unable to communicate. As such, the IS response taken for the greater good of the business was to undertake a complete overhaul of the entire business processes of the company on a global scale, as well as, enabling them digitally. The results were phenomenal, with an annual revenue growth of 15%, a 2% reduction in operating expense, and an increase in internet orders by 50%. The roll out was successful because both the managers and employees had prior knowledge over its importance. Furthermore, the best people got the privilege of spearheading the change process, whereby all the processes mapped with their experts and owners. As such, this spectacular achievement answered the authors question on whether Brady Corporation could redesign its systems for success. The change from old processes to new processes enabled the corporation to revamp its profitability, as well as, re-establish its position in the

International Business - UK and China Essay Example | Topics and Well Written Essays - 1750 words

International Business - UK and China - Essay Example China has a growth rate three times higher than that of Europe, but wage levels there are typically close to a tenth of the UK's. The mere fact that China is such a successful player in the global economy means that small businesses in the UK are affected by the growth of the Chinese market. There are mutual benefits for both UK and Chinese businesses. China has a strong manufacturing base but is in need of technical expertise and innovative technologies that can be provided by Welsh companies. Moreover, there is a strong incentive for Chinese companies to co-operate with Britain as it can be used as a gateway to Europe, and in turn the biggest consumer market in world. Chinese labor costs are very low. There is a fear from some small firms that British manufacturing base could be undermined. Indeed if a large manufacturer relocates to China this has implications for small manufacturers who are first or second-tier suppliers. In terms of labor costs a UK small manufacturer cannot compete and many are suffering as a result. Others indicate, however, that labor is not their highest overhead and when transport costs are included, they believe that they can compete favourably with Chinese products. Moreover, as China's economy develops its workforce, it will grow in wealth and in turn is potentially an extremely large consumer market for goods. Chinese economy presents threats as well as opportunities to British businesses not only as competitor but as the market and supplier. "China and India now encompassed a third of all humanity, and were a potential mass market, supplier and competitor" (Duckers, 2005). Duckers makes a note that British businesses should not think that high value products can be kept while making low value products in China using the cheap labour. In fact, China is turning many times more engineers and technologists than Europe. China is producing half of the world's cameras, refrigerators and TV sets, 30 per cent of air conditioning and washing machines. The growth of Chinese economy has proved to have positive impact on inflation in UK. "According to Monetary Policy Committee member Stephen Nickell, cheap Chinese imports are one of the main reasons why inflation in the UK has remained low in recent years. At the same time, the price of services such as lawyers' fees and haircuts have risen reasonably quickly" (Conway, 2005). In the result of the rapid growth of Chinese economy, more and more British businesses are considering exploring opportunities for trading in China. When getting started the following challenges need to be considered: "Businesses need to ensure they receive a consular briefing before starting business in China and that the Chinese consulate knows in advance of the visit. China is one of the world's most complex markets and companies should send their best people. Employees should be prepared to stay in the region for at least five years to build a successful market. Companies should not start up blind - they need to undertake their own market research in the region before setting up an office or factory. Talking to complementary companies who have already established a successful base about the issues they faced will be hugely beneficial" (Logan, 2005). As Helen Logan continues, the first step is securing a customer base. "Existing, international customers should be targeted first to build the client base,

When I change my major Essay Example | Topics and Well Written Essays - 250 words

When I change my major - Essay Example Since my childhood, I have always dreamt of becoming a successful businessman in my country if not the entire world. I had grown passion for reading business-related articles to expand my knowledge in the filed I considered would significantly shape my future. Consequently, I decided to major in business management during at the beginning of my sophomore year. However, the situation in my country contributed a great deal to the dwindling interest in pursuing business course any further. â€Å"Hey, what do you think about pursuing an engineering course?† It was after this statement from a close family friend, rung a bell in my mind that eventually made me to change my major to engineering.

Global Warming Essay Example for Free

Global Warming Essay Global warming is the increase of Earth’s surface temperature due to the effect of greenhouse gases. The main causes of global warming is the greenhouse effect, fossil fuels in cars, and global emission. Global warming is having an effect on our environment such as rising seas, changes in rainfall patterns, and etc. What we can do to stop this is, lower down emissions, cut greenhouse gases and so on. This paper will focus on what global warming is doing to our environment. The greenhouse effect is one of the things causing global warming. The greenhouse effect is the warming that happens when gases in the earths atmosphere gets trapped with heat. An example of a greenhouse effect is, sunlight passing through transparent windows. The reason it happens is because gases absorb ultra violet heat that is radiated into space. When it is radiated carbon dioxide absorbs this heat and the more carbon dioxide there is in the atmosphere, the air gets warm. If the air gets extremely hot the world will be destroyed because animals and plants will die. Another thing that is causing global warming is fossil fuels in cars. Coals and gas are burned to make electricity, cooking, and warming or cooling our homes. Even though we are using these for our own benefits it is harming our environment and later it will have an effect on us. Fossil fuels are made from remains from other plants, and animals that was buried in the Earth for millions and millions of years. Did you know that a long time ago, that heat and pressure has made these remains into fossil fuels that everyone calls coal and gas? Well today, these fossil fuels are burned so that they can release energy that was stored inside of them. When they are burned the carbon inside of them are released in the air and creates carbon dioxide which is also bad for our environment. Burning petrol’s that are in cars, pollute the air we breathe and is harming both us and the environment but yet we still use it. Global emissions are also one of the things that is causing global warming. Global emission is, worldwide air pollution. Global emissions jumped 3 percent in 2011 which make a huge difference.. There are emissions from factories, greenhouse gases, or global greenhouse emissions. The things that cause global emissions are, carbon dioxide, methane, nitrogen oxides, and hydro fluorocarbons. .This can create smog, and acid rain. Emissions seems to be one of the greatest causes of global warming. This is happening because Earth is surrounded by a layer of gases. Global emissions includes heat creating-gases so when this is released, it rises and becomes trapped by the atmosphere. These trapped gases seem to be responsible for increasing temperatures on Earth. The effect that is having on our environment is rising of seas, changes in rainfall patterns, melting glaciers, spread of disease, warming seas, glaciers shrinking, droughts, and severe rainstorms. Rising sea levels are due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events. The cycle of global warming is changing the climate that all living things have come rely upon. Global warming is making the Earth more humid which causes abnormal temperature and because of it, the weather is changing. The temperature of the Earth has raised 0.4 and 0.8 degrees Celsius in 100 years because of global warming. Glaciers are shrinking because the Earth is warming up. When the seas were warming up, the population of planktons decreased. When the Earth spins, the hat spins with it and the Earth is collecting moisture over the seas. Due to these droughts, farmers are having a difficult time planting, growing, and making a li ving. This paper covered on what global warming is doing to our environment. As it had said in the paper, global warming changed Earths climate, causing the weather to change. The temperature of the Earth has raised 0.4 to 0.8 degrees Celsius in the past 100 years. The things that are often affecting the earth is the effect on greenhouse gases, fossil fuels in cars, and global emissions. Global emissions jumped 3 percent in 2011. Since global warming is harming our environment, we can all work together to find a way to help our environment.

Types Of Trade Unions Commerce Essay

Types Of Trade Unions Commerce Essay A trade union is an organization of employees formed on a continuous basis for the purpose of securing diverse range of benefits. It is a continuous association of wage earners for the purpose of maintaining and improving the conditions of their working lives. Trade union means combination, whether temporary or permanent, formed (i) primarily for the purpose of regulating the relation between (a) workmen and employers, or (b) between workmen and workmen, or (c) between employers and employers, or (ii) for imposing restrictive conditions and the conduct of any trade or business, and includes any federation of two or more trade unions. TYPES OF TRADE UNIONS Since the growth of unions are spontaneous and automatic there is no definite classification that is followed all over the country. However for clear gaps of differentiation the unions have been classified into the following categories. Industrial unions Industrial unionism is a labor union organizing method through which all workers in the same industry are organized into the same union-regardless of skill or trade-thus giving workers in one industry, or in all industries, more leverage in bargaining and in strike situations. For example:- FireBrigadeUnion the National Union of Miners (N.U.M), covering workers at all levels in the hierarchy b) General unions. A General Union is a trade union which represents workers from all industries and companies, rather than just one organization or a particular sector, as in a craft union or industrial union For example:- Indian National Trade Union Congress (INTUC) cleaners, clerical staff, transport workers C) Craft unions. Craft unionism refers to organizing a labor union in a manner that seeks to unify workers in a particular industry along the lines of the particular craft or trade that they work in by class or skill level. It contrasts with industrial unionism, in which all workers in the same industry are organized into the same union, regardless of differences in skill. For example: Musician Unions D) White Collars Union : These are for white-collar (or professional) workers who perform the same or similar tasks in different industries. It represents office workers For example:. National Union of Teachers HISTORY The seeds for the development of trade union in India were sown with the growth of industrialization. As the humanitarian movement came to India in the 19th century, worker groups made several attempts to improve their working conditions. The British introduced this movement in India to divide Indian employers and employees and beat local competition. Attempts were also made to eradicate child labour in India. The British Government was finally compelled to pass a resolution against employing children between the ages of seven to twelve for more than nine hours a day. The trade unionism in India developed quite slowly as compared to the western nations. So far as the question of formation and development of Trade Unions in India is concerned, its necessity was realised from 1875 onwards by philanthropists, social workers like Shri Soirabji Shapaji Bengalle and Shri N.M. Lokhandey. Indian Trade Union movement can be divided into three phases. The First Phase (1850 to1900) During this phase the inception of trade unions took place. During this period, the working and living conditions of the labour were poor and their working hours were long. Capitalists were only interested in their productivity and profitability. In addition, the wages were also low and general economic conditions were poor in industries. Efforts towards organizing the workers were made during the early period of industrial development on humanitarian grounds.In order to regulate the working hours and other service conditions of the Indian textile labourers; the Indian Factories Act was enacted in 1881. As a result, employment of child labour was prohibited. The growth of trade union movement was slow in this phase and later on the Indian Factory Act of 1881 was amended in 1891. Many strikes took place in the two decades following 1880 in all industrial cities. These strikes taught workers to understand the power of united action even though there was no union in real terms. Small associations like Bombay Mill-Hands Association came up by this time. The Second Phase (1900 to 1946) This phase was characterized by the development of organized trade unions and political movements of the working class. A few trade unions like The Printers Union, Calcutta (1905) the Bombay Postal Union (1907) etc were formed. Between 1918 and 1923, many unions came into existence in the country. At Ahmedabad, under the guidance of Mahatma Gandhi, occupational unions like spinners unions and weavers unions were formed. A strike was launched by these unions under the leadership of Mahatma Gandhi who turned it into a satyagrah. These unions federated into industrial union known as Textile Labour Association in 1920. In 1920, the First National Trade union organization (The All India Trade Union Congress (AITUC)) was established. Many of the leaders of this organization were leaders of the national Movement. In 1926, Trade union law came up with the efforts of Mr. N.M Joshi that became operative from 1927. During 1928, All India Trade Union Federation (AITUF) was formed. Besides Gandhi , the Whitly Commission on Labour in India (1929-31) had also pointed out that the Modem industrialism is itself of western importation and the difficulties which it creates for labour in India are similar to the difficulties it has created elsewhere. In these conditions the Commission realised that it is power to combine that labour has the only effective safeguard against exploitation and the only lasting security against inhuman conditions. Moreover the Commission did not find an evidence of any alternative remedy that is likely to prove effective. So it emphasised that the need of organisation among Indian workmen is great and it further recommended that nothing but a strong Trade Union movement will give the Indian working class adequate protection. The Third Phase (After 1947) The third phase began with the emergence of independent India (in 1947). The partition of country affected the trade union movement particularly Bengal and Punjab. The Planning Commission drafted its first five year plan, setting therein necessary targets of production industrial as well as agricultural to be achieved during the next five years. For having industrial advancement, Industrial Policy Resolution in 1948, was also prepared. As the economic progress is bound up with the Industrial peace so for the successful implementation of the plans, particularly in the economy organised for planned production and distribution, the co-operation from Trade Unions was considered absolutely essential at different stages of the execution of the plans. Accordingly, it was realised that the question of maintenance of smooth industrial relations was not a matter between employers and employees alone. But it was a vital concern of the community. Therefore their relationship has to be of a par tnership in this constructive endeavour. This was the reason why it was provided in the first five year plan that the dignity of labour must be recognised so that the workers who on account of hardships of illiteracy and ignorance and lack of opportunities have not been able to play as effective a role in the working of industry as they should, could understand and carry out their responsibility and could take an increasing share in the industry. Accordingly the workers right of association, organisation and collective bargaining was accepted and it was laid down in this plan that they (Trade unions) should be welcomed and helped to function as part and parcel of the industrial system. The necessity of Trade Unions was so much considered that no difference between the workers working in privately owned industries or in publicly owned industries was made. By 1949, four central trade union organizations were functioning in the country The All India Trade Union Congress (AITUC) The Indian National Trade Union Congress (INTUC) The Hindu Mazdoor Sangh (HMS) The United Trade Union Congress (UTUC) The working class movement was also politicized along the lines of political parties. For instance Indian national trade Union Congress (INTUC) is the trade union arm of the Congress Party. The AITUC is the trade union arm of the Communist Party of India. Besides workers, white-collar employees, supervisors and managers are also organized by the trade unions, as for example in the Banking, Insurance and Petroleum industries. OBJECTIVE The objectives of the trade unions generally are: I . They strive for achieving higher wages and better conditions for the members. 2. They not only minimize the helplessness of the individual workers by making them stand collectively and increasing their resistance power through collective bargaining but also protect their member against victimization or injustice of the employers. 3. They provide the worker self confidence and a feeling that they are not simply a log in the machine. 4. They imbibe a spirit of sincerity and discipline in the workers 5. They also take up welfare measures for improving the morale of the workers. 6. They demand an increasing share for workers in the management of industrial enterprises. They help in raising the status of workers as partners of Industry and as citizens of the society. This is another important area, which has a great impact on the industrial relations system. Labour legislation has been instrumental in shaping the course of industrial relations in India. Establishment of social justice has been the principle, which has guided the origin and development of labour legislation in India. The setting up of the International Labour Organization gave an impetus to the consideration of welfare and working conditions of the workers all over the world and also led to the growth of labour laws in all parts of the world, including 1ndia4. Some of the other factors which gave impetus to the development of labour laws in India were the Swaraj Movement of 192 1 -24 and the appointment of the Royal Commission on Labour in 1929. The labour laws regulate not only the conditions of work of industrial establishments, but also industrial relations, payment of wages, registration of trade unions, certification of standing orders etc. In addition, they provide social se curity measures for workers. They desire legal rights and obligations of employees and employers and also provide guidelines for their relationship. In India, all laws emanate from the constitution of India. Under the constitution, Labour is a concurrent subject, i..e., both the central and state governments can enact labour legislation, with the clause that the state legislature cannot enact a law which is repugnant to the central law. A rough estimate places the total number of enactments in India to be around 160. Workers Participation With the outbreak of First World War, countries like England, France, West Germany and USA experienced an industrial unrest largely because labor was regarded as a commodity of commerce which was exploited to its maximum. Because of the unrest they recognized the fact that labor is not a commodity to be sold at a price, but should be treated as human beings having capacity to grow and accept responsibility as citizens. A worker wants to participate in the affairs of the industry and contribute to the effectiveness of the co-operative enterprise to which he belongs. The human relations philosophy popularized by Elton Mayo gave the importance of human factor in the organization. Man is not purely an economic animal but a member of the group sharing its norms and goals. Workers participation aimed at giving the workers a feeling of having a place of their own in the social structure of the country, ultimately providing a social base. The humanitarian approach to labor brought about a new set of values, both for the workers and employers; power has been replaced by persuasion, authoritarianism by democracy and compulsion by co-operation. It is quite logical that people have right to choose their own government, has right to choose the management of the enterprise to which they belong. It rests on fundamental premise that the worker is not a slave who has no rights at all, he is a citizen employed in an industry and has opinions of his own which should be taken into account while formulating the policies and making decisions. The factory is not a mechanical entity which is governed by mechanical principles and economic laws, but a social system which is subject to democratic rights of those who are involved in it. In India, Mahatma Gandhi had already launched the idea of trusteeship after the First World War, and some experiments had followed in the Ahmedabad textile mills. After independence, the Government of India consolidated tripartism and created consultative forums. The various types of involvement with employees varied greatly, though, as several organizations established different practices in India. Information-sharing, suggestion schemes, consultation and, only in a few cases, co-determination or participation in its true sense, exist in many organizations. Issues The issues on which workers or employees are to be consulted have also varied widely. Broadly speaking, the range of issues in any enterprise on which decisions need to be taken from time to time can be classified under five major heads: Safety and Welfare issues; Work-Related issues (production on the shop floor, quality, machine maintenance); Sharing of gains (wages, incentives, allowances); Production-related issues (product-mix, plant production targets, technology) and; Business policy (expansion, contraction, pricing). Workers participation is system of communication and consultation, either formal or informal, by which employees of an organization are kept informed about affairs of the undertaking and through which they express their opinion and contribute to management decisions. It is based on the principles of equity, equality and voluntarism. It gives employees representatives the right to criticize, to offer constructive suggestions, and to become aware of various delicate issues involved in decision-making. The participation enhances employees ability to influence, decision-making at different levels of the organizational hierarchy with assumption of responsibility. Participation Refers to mental emotional involvement of Workers in unions activities it is more behaviorist rather than an attitudinal concept. Indicators of participations 1-participation in unions elections 2-membership enrolment subscription 3-membership on union committees 4-Attending unions meetings 5-Involvement in unions welfare social responsibility functions. Factors influencing WP in Unions 1-The type of leadership is available in unions 2-the history of labour management relations in a plant 3-the age, experience, skills educations, caste, employment of workers. 4- the style of supervision, motivation, morale, wage structure in the industry. 5-Welfare measures fringe benefits available to workers. Advantages of W.P in Unions 1-W.P in unions activities gives solidarity strength to the unions. 2-It helps in developing leadership from the rank ensures a strong bargaining power. 3- it checks the tendency on the part of selected leaders to become all powerful by a vigilant participative membership. 4-It is essential not only from the viewpoint of betterment of unions leaders but for the very success of trade unionism. Employers Associations Effectiveness of any industrial relations system whether based on legislation or voluntary arrangements, depends to a great extent on the attitude that unions and employers organizations adopt towards each other. The intention in covering employers organizations under the Trade unions Act, 1926 was to place both workers and employers organizations on a par in matters of rights and responsibilities. the principal of giving equal representation to capital and labour on all consultative bodies like the Indian Labour Conference, Standing Labour Committee and industrial committees recognizes this basic tenet in the employer- employee relationship. Functions Communication Advisory Functions Educational Efforts Representational Functions Functions of Social Responsibilities TRADE UNION ACT, 1926 The Trade Unions Act was passed in 1926 under the title of the Indian Trade unions Act and was brought into effect from 1st June 1927. The act was amended in 1947, 1960 and 1962. Subsequently, the word Indian was deleted from the amended Act of 1964, which came into force from 1st April 1965. Objectives of Act Terms and conditions required for trade unions to become officially registered. Responsibilities expected from a registered trade union. Rights and liabilities of registered trade unions Applicability of the Act The Act extends to the whole of India. The act was extended to Jammu Kashmir by the Central Labour Laws Act 1970 with effect from 1st September 1971. The Act applies not only to the unions of workers but also to the associations of employers. The Act is a central legislation, but it is administered and enforced mostly by state governments. For the purpose of this act, the Central government handles the cases of only those unions whose activities are not confined to one state. All other unions are the concern of state governments. The registrars of trade unions are appointed both by the central and state governments. They can also appoint additional or Deputy Registrars who may exercise the powers and functions of the Registrars, as they think fit so as to obviate delays in the disposal of applications for the registration of trade unions. Scope (a) Only persons engaged in Trade or Business (which includes an Industry) can form a trade union or become members of the trade union. As such persons employed in Raj Bhawan for domestic and other duties cannot form a trade union. Likewise, the government servants engaged in the task of sovereign and legal functions are not entitled to the registration of a trade union. (b) The Trade Unions Act 1926 applies to the whole of Indian Union. (c) Any person who has attained the age of 15 years may become the member of a registered trade union. Functions of Unions The functions of unions include intramural, extramural and political. Intramural functions are those activities which are at the betterment of needs of workers in relation to their employment such as ensuring adequate wages, securing better conditions of work, rest interval, continuity of employment etc. Extramural activities are those which perform to help the workers in times of need and improve their efficiency. They also include welfare measures and conduct recreational functions for the workers. The history of trade unionism in the country records profound effects of political leaders. The route of action, the concentration of work moves from workers to a more universal area- politics. In India most of the unions are politically affiliated or have strong support of leading political parties of the country. Thus the trade unions use their franchise to capture the government which indirectly results in acquiring stronger hold of power through political influence for their trade union. Penalties A. Failure to submit returns (Section 31): Section 31 of The Trade Union Act, 1926 states about the penalties on failure to submit returns by registered Trade Union.

EXISTING TRADE UNIONS At present there are 10 Central Trade Union Organizations in India: All India Trade Union Congress (AITUC) It was established in 1920 as a result of a resolution passed by the organized workers of Bombay and the delegates which met in a conference on 31 October 1920. It was attended by such first rank political leaders as Motilal Nehru, MA Jinnae, Mrs. Annie Besant and Vallabhai Patel and Col. Wedgewood on behalf of the British Trade Union Congress. The first president was Lala Lajpat Rai. Bharatiya Mazdoor Sangh (BMS) This union has been the outcome of the decision taken by the Jana Sangh in its convention at Bhopal on 23rd July, 1954. Centre of Indian Trade Unions (CITU) This was formed in 1970 when as a result of the rift in the AITUC; some members of the Communist Party seceded. Hind Mazdoor Sabha (HMS) When the Socialists separated from the Congress, those who were dissatisfied with the pro-Communist policies of the INTUC formed a new organization, the Hind Mazdoor panchayat, which was merged with the Indian Federation of Labour in 1948 under the name of the Hind Mazdoor Sabha. It is an organ of the Praja Socialist Party. Indian National Trade Union Congress (INTUC) The INTUC came into existence on 4th May, 1948, as a result of the resolution passed on 17th November 1947, by the United Board of the Hindustan Mazdoor Sevak Sangh, which was a labour organisation working under the direction of National Congress-minded labour leaders on the Gandhian Philosophy of Sarvodaya. Since AITUC was under the stronghold of the Communists, the Congress labour leaders thought of forming a new central trade union organization. To give effect to this idea, a conference was held at New Delhi under the chairman ship of Sardar Vallabhai Patel. It was inaugurated by Shri Acharya J.B. Kripalani (on May 3, 1947) and was attended by eminent nationalist and socialist leaders. National Front of Indian Trade Unions (NFITU) This union was founded in 1967, with the claim that this is the only trade union in India which is not controlled by any of the political parties, employers or government. National Labor Organization (NLO) Trade Unions Co-ordination Centre (TUCC) Trade Union Coordination Committee is a central trade union federation in India. TUCC is politically attached to All India Forward Bloc. According to provisional statistics from the Ministry of Labour, TUCC had a membership of 732760 in 2002. The general secretary is Nripendra Kumar Mahto. United Trade Union Congress (UTUC) Some trade union leaders of the socialist bent met together in December 1948 to form a new central organisation of labour, called Hind Mazdoor Sabha. Some of the leaders did not agree with the principles and objectives of the Sabha and they therefore, again met at Calcutta on December 27, 1948, and decided to call upon a conference of trade union leaders to form a united Trade Union Committee. This Committee called for a meeting of the various leaders at Calcutta on April 30, 1949 and formed a new union under the name of United Trade Union Congress. United Trade Union Congress Lenin Sarani (UTUC LS) It is a Central Trade Union Organisation in India and the labour wing of the Socialist Unity Centre of India (Communist). Presently its activities are spread over 19 states. The organisation claims to have 600 affiliated unions, comprising an individual membership of over two million. It is the 6th largest trade union in India. According to provisional statistics from the Ministry of Labour, UTUC-LS had a membership of 1,368,535 in 2002. AFFILIATED ORGANISATIONS UNDER INTERNATIONAL TRADE UNION CONFEDERATION Hind Mazdoor Sabha (HMS) 5,788,822 Indian National Trade Union Congress (INTUC) 8,200,000 Origin: Came into existence on 4th May 1948,as a result of the resolution passed on 17th November 1947,by the central board of the Hindustan Mazdoor Sevak Sangh. Objectives: It aims at the sarvodaya ideal and stands for gradual transformation of the existing social order. It aims at establishing a socialist state in India. It aims at placing industry under national ownership and control in a suitable form in order to realise the desired order of society. Methods Used: These strike is like a Brahmastra and is not to be resorted to in a light-hearted manner and made cheap and blunt. Political Affiliation: Affiliated with the Indian Natinal Congress (the ruling party). Its relations with the government are based on the mutuality. Self-Employed Womens Association (SEWA) 1,325,752 STRUCTURE The structure of unions refers to the basis on which unions are organised (i.e., whether they are organised on craft or industrial or general union basis) and to the pattern whereby the plant unions are linked to regional level or national level federations or unions. Unions in India are largely organised by industry rather than craft. Although industrial unionism has been the general trend, craft unions have also emerged here and there; primarily, they exist among non-manual workers like administrative staff, professionals, technicians, etc. Ahmedabad Textile Labour Association is the sole example of craft union of manual workers. Another aspect of the structure of unions in India relates to their pattern of relationship between national level, regional level, local level and plant level unions. Let us see how they are related in India. Plant level Unions The first level in the structure from below is the plant level union. This comprises the unions in one organisation or factory. Please note that only seven members are required to form a union. This has lead to multiple unions in one factory Local Level federations. This is the second level in the structure from below. The local trade union federation holds together the plant level unions at the local level in a particular craft and industry. These local level federations might be affiliated to either some regional level or national level federation or these may be independent. Regional level federations These are the organisations of all the constituent unions in a particular state or region. The importance of such federations cannot be exaggerated. In a country like India, conditions vary from region to region. The style of living, languages, customs, traditions, conditions, etc. are different. Therefore, it is better that workers are organised at regional or state level. These regional federations may have members of two kinds: (1) The plant level unions affiliating themselves to these directly and (2) The local federations. In the second case, plant level unions become the members of regional federation indirectly through the local federations. It may be noted that the regional federations may be independent or they may get affiliated to some national federation. National federations. These are national level bodies to which plant level unions, local unions or regional level unions may get affiliated. These are the apex bodies at the top of the structure. They act as coordinating bodies. Th
