Growth of Tractors in India: Past and Future

Girja Sharan and Kayastha Sandeep

A casual, discrete, dynamic mathematical model to describe the growth of tractors in India has been proposed. It is able to describe the past pattern of growth quite closely, and yields results that are much better than possible from methods available in literature. Therefore, it has been used to outline scenarios till the year 2000. The model appears promising and needs to be tested further on independent set of data from individual states.

An Explanatory Study of Viewers Perceptions of Television Advertising

Gupta Nirmal

Study of Consumers' attitude towards advertising helps the advertisers in planning their advertising campaigns. By comparative evaluation of advertisements across different elements viz. Creative strategies, appeals and execution styles, the advertisers can select appropriate 'content mix' for their campaigns. The present study attempts to explore the role and effectiveness of different elements of an advertisement (i.e. Creative Strategy, appeal and execution style) on the Viewers' attitude for it. The study was carried out for 24 television advertisements and the overall attitude of 50 viewers was evaluated by using attitude measuring scales. Advertisements were selected after a comprehensive content analysis, of a large number of advertisements which classified them under different elements. The items on the attitude scales were chosen in such a manner so as to tap all three components (viz. Cognitive, affective and conative) of attitude. The study concluded that there was no significant association between the single element of an advertisement and viewers' attitude for it. No association was found even when combinations of two elements at a time were evaluated against viewers' attitude. It appears that viewers do not form attitudes for advertisements on the basis of one or two elements but they perceive it as an integrated whole.

Redefinition of Social and Organisational Roles

Parikh Indira J and Garg Pulin K

This paper explores the institution of marriage and work organization as held by women. Both systems demand responses from women for which they are often not prepared. Their dreams of romanticised marriage and fantasy of togetherness often lead them to dis-illusionment and dis-enchantment. Their career aspirations without the reality appraisal of organisations and their own definition of systems lead them to frustrations. They are pulled and pushed between social and organization role demands, and their own entrenchment in stereotypes of role taking. The conflict between the desired and the aspired daughter-in-law, wife and mother roles on the one hand and desired, aspired professional and career role on the other hand creates conflicts, stress and guilt. Women get caught with the internalization of the normative prescriptive modalities of social and work systems. The role models from family, culture and history are insufficient and inadequate for meaningful responses. This paper explores those areas of role taking by women which can help redefine and redesign new responses in both the systems. It deals with the reinterpretation of existing roles and arriving at an integrated perspective for women which can bring convergence within both the systems of family and work. This paper suggests that women who encounter in themselves the women-person dilemma and take charge of their own destiny in their hands to give it a shape, form and a meaning finally come to make choices for the wellbeing of both themselves and the system. In the absence of such an integration, women when confronted with the turmoil of the two systems either become conformists or rebels or exile themselves and end up making compromises rather than choices.

Industrial Sickness in India: Magnitude and Identification Criteria

Dholakia Bakul H

The main purpose of this paper is to examine the criteria used by official agencies to identify industrial sickness and highlight the limitations of such identification criteria especially in the context of the nature of remedial action that needs to be taken to deal with this problem. Available empirical evidence indicates that, in the case of large industrial units, industrial sickness appears to be more of an industry-specific problem than a general problem as such. Official yardsticks for identifying industrial sickness are based on the criterion cash loss and the criterion of net worth erosion. Such criteria have the undesirable effect of delaying the identification of isck units by at least a couple of years or more. The recent concept of "weak" units is also unlikely to achieve the purpose of detecting industrial sickness at the incipient stage. As a result, a large proportion of the identified sick units is found to be non-viable and, therefore not eligible for any rehabilitation package. Under these circumstances, restructuring the procedures adopted by the financial institutions for identifying industrial sickness and introducing appropriate systems for early detection and prevention of sickness appear to be the main long term remedy for this problem.

A Lot Size Model with Discrete Transportation Costs

Gupta Omprakash K and Rao P Poornachandra

The classical Harris-Wilson inventory model does not explicitly account for the costs incurred in transporting goods from the supplier to the buyer. Either such costs are assumed to be fixed and considered part of the ordering costs or they are assumed to be variable and are included in the item costs. In many situations, however, it is observed that a fixed cost is incurred for a transport mode, (of a given capacity), such as a truck or wagon. The very nature of this type of transport mode requires hiring of an integer number of trucks or wagons. Therefore the transportation cost function becomes a discrete function. In this paper we develop an inventory model with discrete transportation costs, and present an algorithm for the optimal lot size. Finally an example is given to illustrate the methodology.

Development of a Psychometric Measure of Learned Helplessness (LH)

Pestonjee D M and Reddy Prathap

Behavioural sciences have constantly attempted to bring greater rigour in their measurements. Tests and instruments represent one such attempt. The aim of the present research is to evolve and develop a scientific tool for measurement of the 'learned helplessness' (LH) concept. The authors have taken into account such attributions as: internal-external, stable-unstable, and global-specific. With the help of factor-analysis, eight of factors have been extracted and a 24-item scale on LH has been standardised.

Market-Wide Commonalities in Corporate Earnings and Significance Tests of Accounting Beta

Bhat Ramesh

The annual earnings performance of a company reflect numerous events. Some of these events affect almost all the companies in the economy whereas some are specific to the industry in which the company is operating. The objective of the present paper is to discern and quantify the influences arising primarily because of economy-wide factors. They are referred as market-wide commonalities in corporate earnings. This has been done by using the market model framework. The study uses a sample of 182 companies from the population of companies listed on the Bombay Stock Exchange The earnings and book rate of return series of 17 years for each company is used to construct the market index. The accounting earnings beta estimates are obtained for each company by using OLS method. The market model has been tested in its various forms. The model consistent with OLS specification has been considered to be more relevant in interpreting the results. The hypothesis that there is a systematic index does not find empirical support. The explanatory power of the models consistent with OLS assumptions has been found to be very low.
