Training Functions in India

Saiyadain M S

This is a state-or-art survey of the training functions in India. Data was collected from 49 organizations varying in size, turnover, product, technology, sector and geographic location. Major findings suggest one-third of the organizations have separate training departments manned by professionally trained managers. In two-third of the cases training functions are manned by those who do not have formal qualification for training functions. The training infrastructure is nominal and a very small portion (.017%) of the total budget of human resources is spent on training. Most organizations identify training needs through appraisal reports. More than two-third organizations have formal induction training, organize in-company training programmes and sponsor many more managers than supervisors and workers to external training programmes. Training feedback is taken seriously by most of the organizations.

Transient Analysis of Multiple Unit Reliability Systems

Sharma O P, N. Ravichandran, and Dass J

A general Markovian model representing several multiple unit redundant repairable system is proposed and it's transient behaviour is studied. Specifically, for multiple unit reliability system the reliability and availability functions are derived in an explicit form for the transient case. The stationary availability and mean time to system failure are deduced from the main results as special cases.

Prediction of Job Performance by Indian Managers: Four Tests of the Two-Stage Averaging-Multiplying Model

Singh Ramadhar and Upadhyaya Sushil K

Prediction of job performance from information about motivation and ability of subordinates was studied. Experiment 1 made the first test by manipulating reliability of information with managers (n = 22) and professors (n = 22). At the first stage of integration, subjects averaged motivation and ability information with their corresponding initial opinions. At the second stage, however, they integrated motivation and ability information differently. Managers followed the multiplying rule; professors followed the constant-weight averaging rule. Experiment 2 (n = 22) paired three or one motivation cue with one ability cue. Predictions from information about either motivation or ability were also obtained. The three motivation cues were first averaged and then multiplied by ability as Test 2 predicted. The combined factorial plots of the Motivation x Ability effects from the two-cue and four-cue descriptions also had the linear fan pattern prescribed by Test 3. However, Test 4, which predicted that the initial opinion of the unavailable information would multiply the given information, needed an additional parameter of imputed value for the unavailable information. Theoretical, methodological, and practical implications of the results were discussed.

Dividend Rate and Variation in Share Prices: An Exploration into their Inter-Relationship

Ravindra H. Dholakia and Bhat Ramesh

Return and risk are the two acknowledged characteristics affecting investment decision of investors in securities market. The literature on the relationship between these two characteristics provides ample evidence about the interdependencies between them. The present study takes a view that risk should not be considered a one dimensional variable. An attempt has therefore been made in the present paper to decompose this characteristic into risk in dividend and uncertainty in capital gains. Two alternative explanations for the nature of their interdependencies and provides cross-section-one period analysis of dividend and share price variables. The empirical evidence supports the hypothesized relationships between the two dimensions of risk.

Crew Scheduling in Indian Railways - A Case Study of Vadodara Division Passenger Train Crews

G. Raghuram, V. Venkata Rao, and Saha Jahar

In this paper we discuss the crew scheduling problem in Indian Railways and propose a methodology to minimize crew requirements. In Particular, we deal with the scheduling of passenger train crews in Vadodara Division of Western Railway. In Part-I of the paper, we describe the organization of Indian Railways, highlight the decision making process and give a brief description of the crew categories. We end Part-I by giving the regulations relevant for the scheduling decisions and a formulation of the problem as of determining a 'crew link' that requires minimum number of crews. In Part-III we describe the 'A-D Sequence' methodology and discuss how this is used in evaluating a 'Crew Link' for the drivers of express trains in Vadodara Division. In conclusion, we remark that the methodology is very general and it could be used for scheduling of all category of crews for passenger trains.

Demand Forecasts for Cultural and Industrial Papers in India: Some Policy Implications

Gupta Tirath

Number of integrated pulp and paper mills in India increased from 17 in the early 1950s to 250 in 1985, and the production capacity rose from 137,000 tonnes to 2,350,000 tonnes. The capacity utilization, however, declined continually from 90 per cent during 1951-56 to 58 per cent during 1980-85. This is attributed to a number of factors chief among which are the predominant role of ambitions and presumptions, and lack of distinction between need and demand in the planning process. Besides the official documents, an assessment of the studies to forecast the demand for paper on the basis of i) changes in income, ii) changes in incomes, expenditure on education, index of industrial production, etc., and iii) limited end use surveys; also indicated that there has been one way difference between the demand forecasts and observated consumption levels during 1960-85, and the former were higher than the latter by 7 ato 97 per cent. The variations within the projected demand levels for any year have been even more pronounced. Some of the reasons for these variations have been the differences in i) type of association assumed between explanatory and dependent variables, ii) type of data used in the studies, iii) assumed growth rate for the explanatory variables, iv) the number of explanatory variables included in the models, v) subjective judgements of the analysts and users of the results, etc. The last of these has been facilitated by non-availability of adequate or accurate data, and inadequate modelling work such that the demand forecasts have not been approached in a systems framework. The forecasts have not served as appropriate tools for production planning and policy making this may be achieved if adequate and reliable data on consumer profile are collected and processed to enlighten the analysts on how much of different types of paper and paperboards are consumed by different socio-economic groups for different purposes. This may be the best time to generate the data as the nations need not plan for additional production capacity for at least the next 5 years.

Averaging Model Analyses of Teacher Expectations of Performance from Students Varying in Motivation and Ability

Singh Ramadhar and Shoba Sneh

Although there have been numerous studies of the impact of teacher expectation on student performance, the manner in which expectations are formed has remained unexplored. The present research tested the hypothesis that teachers develop expectation of student performance by averaging information about his or her motivation and ability. In two experiements on prediction of performance in nonacademic contests (n = 60) and academic exams (n = 60), manipulations of number of pieces of similar motivation information, availability of additional pieces of average motivation information, and unavailability of information about either motivation or ability all yielded results as prescribed by the averaging model. Motivation information received not only less importance than ability information but also got discounted when it differed markedly from that of ability information. As this result differs from those previously obtained from students and managers, the second hypotheses of role differences in expectation of performance was also supported. Theoretical, methodological, and applied implications of the results were discussed. Suggestions for future research were also made.

Prediction of Son Performance in Easy through Difficult Exams by Indian Parents

Singh Ramadhar and Mehta Mridula

Prediction of exam performance from information about motivation and ability of students by Indian subjects always supported an adding-type rule. As this rule implies that motivation is equally effective with persons of low through high ability, it may be regarded as reflective of an idealistic philosophy. The present research tested the hypothesis that a multiplying-type rule which implies that motivation is more effective with persons of high than of low ability may be used by Indian subjects if the situation demands realistic estimates. Twenty-four couples expressed expectations from their only-son in easy through difficult exams to school principal confidentially. Predictions by mothers obeyed the multiplying-type rule; those by fathers obeyed the adding-type rule. Exam difficulty changed pattern in father's judgments but not in mother's judgments. However, parents held a similar belief: Effectiveness of motivation increases with sons of high ability but decreases with sons of low ability as difficulty of exam increases. Of the three possible explanations for the effects of exam difficulty, changes in weight of information seemed to be the most parsimonious.
