An EOQ Model Under Price Change Anticipation for A System with Insufficient Storage Capacity

Shah Nitin and Shah Y K

When a price change is announced in an inventory system, a one time decision has to be made to purchase a large quantity Q' before the price change becomes effective, to take advantage of current lower price. In this note, we consider a system having a limited storage capacity W<< Q', so that additional units are required to be stored in rented warehouse. Optimum value of Q' and corresponding gain are determined. The model is illustrated with an example.

MOU: More Memorandum than Understanding

Murthy K R S

The Memorandum of Understanding (MOU) between the Government of India and public enterprises is the latest technique adopted to improve management of these enterprises. Will the MOU's improve the situation? Based on the experience so far, as also international experience with MOUs and management of large diversified corporations, this paper discusses why MOUs may not achieve the results expected and indicates the direction in which solutions should be sought.

Leadership and Human Resource Management Styles of Senior and Top Level Managers

T. V. Rao, Selvan Tamil S, and Kumar G Arun

This paper reports in detail a Leadership Styles Questionnaire (LSQ) developed to measure the Benevolent, Critical and Developmental styles of manages. This questionnaire has two forms; one for self-assessment and the second for assessment by others (subordinates, boss and colleagues). This questionnaire is being used as a training instrument to help managers review and reflect about their own people management and leadership styles and beliefs underlying these. The instrument was used first on 74 senior managers to assess their own styles and the styles of their seniors. Subsequently it was used on 67 senior managers who were also assessed by their subordinates (n = 540). It was also administered on 96 top level managers who were assessed also by their subordinates (n = 871). In all the cases it was used as a training instrument. This paper presents the data available from all these groups and offers suggestions for using LSQ as a development tool in training programmes, counselling, appraisal and OD. The data indicate that the leadership styles of senior executives as well as top level managers is predominantly "Developmental". The data also suggest that Indian managers seem to be sensitive to the perceptions of their subordinates as there was a good degree of congruence between their perceptions and those of their subordinates. In cases where the managers were perceived as "critical" by their subordinates, the managers were found to be less sensitive to such perceptions. These were however, only a few in number. Detailed data are presented in this paper for use by those interested in using the LSQ.

Computer Graphics, Peripheral Vision & Non Euclidian Geometry

Jayanth R. Varma

Computer graphics in Decision Support Systems is often confronted with the task of providing the decision maker with a visual picture of some object which is too large to fit on a computer screen unless the image is scaled down so drastically that much of the detail is lost. The viewer is then asked to work with a partial view of the object, and use a keyboard or a mouse to (a) scroll this image horizontally or vertically, or (b) zoom in or out, or (c) rotate the object. These techniques are strikingly similar to those that the human visual system uses to deal with a similar problem. One crucial difference is that of peripheral vision-the human eye while concentrating on a small part of the field of vision still retains a hazy view of the peripheral region preventing it from losing sight of the total picture. This paper argues that the lack of a similar peripheral vision is perhaps the single gravest deficiency in computer graphics today. It then goes on to develop a mapping technique which simulates this peripheral vision, and thereby makes computer graphics truly powerful and versatile. The paper analyses the distortions induced by such a mapping, and argues at length why these do not pose serious problems. The suggested mapping is closely related to non Euclidian geometry; this ties in with the fact known to psychologists for over fifty years that the perceptual geometry of human visions strongly non Euclidian. Thus, if one were to adapt the Turing test for artificial intelligence to computer vision, then non Euclidian geometry can be expected to play a key role in any attempt to satisfy that the test. Building on these ideas, the paper demonstrates that computer graphics has a great deal to lean from non Euclidian geometry, and that in turn computer graphics can contribute significantly to the intelligent application of non Euclidian geometryies to real life problems. What is needed is the willingness to set aside the shackles and shibboleths of Euclidian geometry.

Threat Bargaining Problems with Incomplete Information and Correlated Beliefs

Lahiri Somdeb

In this paper we provide a general framework for studying threat bargaining games with incomplete information and correlated beliefs. In this framework we obtain a characterization of the Kalai-Smorodinsky solution without any monotonicity assumption. The approach adds a dose of realism to the already existing literature on threat bargaining games.

European Economic Community: Underlying Motives and Their Implications

Gaikwad V R

This is the Introductory chapter to Author's forthcoming book entitle, “ European Economic Community and Non-European Communities”. What is happening in Europe is gigantic with far-reaching implications for Indian and other developing countries. The paper analyses in depth the ideas of Jean Monnet, the Father of European Economic Community, and the basic motives underlying formation of EEC and their implications. Common Market is only a strategy to achieve the primary politico-economic objective namely, a United States of Europe. The process by which Common Market might become a supra-national state is shrewdly set up in such a way that process is gradual and imperceptible. The recent developments in East Europe and Russia are not spontaneous but part of the long-term strategy for uniting Europe and people of “European Origin”, and for “Unity of West”. Europe's march from Nationalism to Supra-nationalism may lead to Euro-racialism, creating a threat of War of Races in near future. India and other developing countries which are mostly non-European countries have to keep in mind these implications of EEC.

Growth of New Stoves - A Model

Girja Sharan

Promotion of new wood stoves has been made into a nation-wide time-bound program. At present, setting of targets in each area proceeds somewhat arbitrarily. Generally, no account is taken of the mechanics of absorption. This paper deals with this problem. A mathematical model of the process is formulated. Under reasonable assumptions, it leads to a linear, time-invariant, discrete system. Possible growth patterns that emerge are illustrated. The model is easily built and easily solved. It can be helpful to those who plan, implement and monitor the program.

Review of Post-Graduate Research in Agriculture (1973-1984): Are We Building Appropriate Skills for Tomorrow

Gupta Ramesh, Simmons George B, and Shah Rekha N

Post Graduate Research (PGR) has been an important source of generating technological breakthrough in social as well as natural sciences. The skills for solving problem of 21st century have to be created now. We have reviewed all the abstracts of PGR reported to Haryana Agricultural University Journal of Abstracts of the period 1973-1984 (n = 1817). Five disciplines viz., Genetics and Plant Breeding (n = 242), Economics, Sociology and Extension (1229), and Agronomy (376) were selected for analyzing these abstracts from the point of view of area, method, purpose, commodity/crop etc. of the study, Despite various limitations of the data, several vital research gaps emerge. We have specifically focussed on the importance attached to the problem of rainfed/dry farming regions. Suggestions have been made for (a) making research on risky problems more attractive for students by modifying degree granting system and providing attractive fellowships, (b) periodically reviewing PGR so that corrective measures can be taken, (c) encourage research on research process itself, and linkage between on-station and on-farm research. Some other problems which need urgent attention are: crop-livestock interactions, institution building for common property resources as well as private resources under watershed development; problems of pastoralists rearing small and large ruminants, effects of stress fodder on post-drought performance of livestock; hand tools, conjunctive use of organic and inorganic fertilizer, breeding for low input environment as well as for grain and fodder quality and quantity; screening under inter or mixed crop environments for crops that are predominantly sown under such conditions; longitudinal research on ecological systems including watershed, household adjustment with risks in different agro-climatic zones etc.
