Regionalizing A National Input-Output Table

Dholakia Bakul H

In the present paper it is argued that the most popular among the non-survey methods the RAS method is not a consistent and efficient method to regionalise the national input-output tables. An alternative non-survey method is, therefore, proposed as a solution to the problem when data on industry/commodity-specific value added as well as final demand are available besides the gross outputs at the regional level.

Learning Relationships Among Classes Specified by Examples

Yegneshwar S

Learning by examples is a commonly used method of knowledge acquisition in expert systems. The learning examples are past cases whose classification is known. When the number of classes is high, learning relationships amongst classes aids in sequential classification and therefore results in better explanations. A methodology to learn relationships amongst a given set of classes aids in sequential classification and therefore results in better explanations. A methodology to learn relationships amongst a given set of classes using a distance measure is described in this paper. This distance which is shown to be a metric is evaluated on the descriptions of the classes. The description of a class is learnt from its examples. The relationship learnt using this distance metric is shown to converge in the limit. The methodology described learns meaningful relationships for two applications commonly used by machine learning research groups.

Estimating Biomass Potential for Biofuel Conversion in India: Some Methodological Issues

Moulik T K and Mehta Swati

As resources diminish and needs increase, it has become important to utilize waste materials as fuel. This paper discusses some methodological issues on the biomass conversion into fuel. Biomass is an organic matter formed by plants, trees, agricultural crops, crop residues, and by-products of forestry and agricultural industries. Utilization of indigenously available biomass resources can reduce the production cost and alleviate the problems of disposal and pollution.

Values in Search of Education

Sheth N R

This paper is based on an amateur research effort to understand how social values are transmitted through non-formal education. The point of departure for the study lies in some currently expressed views on deterioration of values in society with serious implications for human survival and welfare. The nature of values as a part of social reality makes it difficult and hazardous to identify and observe them in an objective study. Values would have to be chosen and examined somewhat arbitrarily. In such an arbitrary framework of values, the author has described the value education component of the activities of three projects in socio-economic development. The description is followed by some tentative thoughts on education in values. At the end, some candid questions are raised on the theme of the paper.

Conserving Diversity of Sustainable Development: The Case of Plants of Insecticidal and Veterinary Medicine Importance

Anil K. Gupta, Patel Kirit, and Patil B L

The debate on north-south relations, sustainable development and maintenance of biodiversity has assumed renewed seriousness in the light of current controversy on intellectual property rights. While the right of the nations have been taken into account, rights of the poor people who have produced or maintained much of the ecological knowledge have not been adequately acknowledge. The paper provides list of several hundred plants which have been used for veterinary medicine or plant protection purposes by the local people in India and elsewhere. Our continuing work on documentation of local technical innovations and ecological knowledge systems indicates considerable potential for building upon peoples' knowledge for developing sustainable technologies. We recognize the need for cataloguing this knowledge more systematically so that inter-disciplinary screening can take place for extending in some cases the frontier of science. Institutional arrangements will need to be made so that the producers and preservers of this knowledge are not denied fair returns from the local resource or a local practice when it is commercialized. We also argue that the descriptors of germplasm used in various gene banks need to be modified to acknowledge and catalogue the cultural and ecological knowledge of the people associated with a given local crop variety or an animal breed. It is also hoped that systematic research on plant-derived pesticides might help in reducing and in due course eliminating the hazardous chemical pesticides. A strong case is made for redefining the framework for conservation of bio-diversity so that stakes and insights of local people become the basic building block of future developmental strategies and interventions.

Sustainability Through Biodiversity: Designing Crucible of Culture, Creativity and Conscience

Anil K. Gupta

There is a widespread concern world over about non-sustainability of present developmental strategies and structures in both developed as well as developing world. Most debates have however, ignored the relationship between the region of high biodiversity and high poverty (see IIM Working Paper NO.938). in this paper we have not only pursued the cultural and institutional roots of this relationship but also identified practical ways in which the people preserving biodiversity can be compensated. Paper makes a strong case for changing the nature of discourse and modifying existing epistemology of environmental debate. In part one, the relationship between diversity and deprivation is analyzed. In part two, the cultural and institutional aspects are studied. In part three, examples form indigenous ecological knowledge system including nature related folk songs generating eco-ethics are reviewed. Cultural diversity and the traditions of indigenous enquiry are pursued in part four. In part five, we discuss the reasons for protests emerging from these regions and the nation state's response. In part six, I discuss the mechanism for compensating farmers for preserving diversity. In part seven, the legal, fiscal and organizational routes for paying compensation are described. Part eight lists the ethical dilemma in conducting discourse on bio-diversity. In last part, areas for follow up action by academics, planners and NGOs are illustrated.

Survey of Strengths and Weaknesses of Senior Executives as Perceived by them and their Juniors

T. V. Rao and Selvan Tamil S

Survey of strengths and weaknesses of senior executives was undertaken in the context of increased use of self-awareness and personal growth programmes in through feedback and counselling. Survey had the objectives of finding out (i) Characteristics or qualities that are perceived by Indian managers as contributing to their effectiveness, (ii) Characteristics or qualities that are perceived as hindering the effectiveness of Indian managers; (iii)Most frequently mentioned strengths of Indian managers as perceived by their subordinates; (iv) Most frequently mentioned weaknesses of Indian managers as perceived by their subordinates and (v) Qualities or characteristics in which there is good degree of agreement in the perceptions of the subordinates. Various characteristics that contribute managerial effectiveness were grouped under six categories: 1. Technical or technological competencies; 2. Managerial and systems competencies; 3. Human relations competencies; 4. Group/team building competencies; 5. Leadership competencies; and 6. Other personal characteristics. It was found that senior executives frequently mentioned managerial and human relations competencies (out of the six said above) as the qualities contributing to managerial effectiveness. Also, of the six categories, personal characteristics and human relations competencies have been identified by the managers as hindrances to effectiveness. Thus we find personal qualities and interpersonal competencies playing a greater role in making a manager to perform effectively. Subordinates have perceived the strengths of their bosses and have stated that their bosses are technically knowledgeable, have planning and decision making skills, delegation ability, communication and motivation skills, leaderships, commitment, hard work and posses other personal characteristics like cool headedness and sincerity. There was agreement in perception relating to strengths like technical knowledge, hardwork, aggressive and cool headedness. In their perception of weaknesses of their bosses, subordinates have identified, poor communication abilities, poor delegation, inability to motivate subordinates and poor planning as some of the weaknesses. There was consistency in the cases of weak in communication, short temperedness and low involvement or aloofness. Subordinates have felt that, improving interpersonal relationship, communication and time management would further enhance the effectiveness of their bosses. Thus, we are able to see a consistency in the case of human relations competency, a competency which both managers as well as subordinates feel is very important for improving managerial effectiveness. As a whole, the study brings out the relevance of personal development and human relations skill to management.

Dispatch Planning of Finished Steel: A Case Study in Modeling and Data Analysis

Kalro A H, G. Raghuram, P. R. Shukla, and Tripathy Arabinda

A steel plant has to dispatch products to forty four stockyards from a range of over hundred stock keeping units. The railways, who transport the steel, would like the steel plant to move the steel in a rake load since it is operationally beneficial. On the other hand, the steel plant prefers to move the steel with a shipment size as small as a wagon load. This paper attempts an analysis for the desirable shipment size between the rake load and the wagon load. This is done by first evaluating the requirements of the average finished goods inventory as a function of the percentage of dispatch by rake load, using a simulation model. A national perspective is then used for this decision since the railways are a crucial national resource. Having concluded that the rake load is the desirable shipment size, a decision support system is developed for the loading and production expected in the short term, take load (shipment size) requirements for various destinations, the rake formation constraints at the loading points etc. the paper also proposes longer term strategies to help increase the rake load dispatches.

Spatial Optimisation of the Fuel Purchase Decision for Road Transport Undertakings

G. Raghuram

Road Transport Undertakings in India have been spending approximately between 15-20% of their total expenses on fuel. Given the fact that they visit different towns and sometimes even different states, the fuel which is available at different prices could be purchased in a way that the fuel cost is optimised. A network model, algorithms and linear programming formulations are presented for this problem in order to decide how much fuel should be purchased at the different towns that a bus visits as part of its vehicle duty schedule. The model presented minimises the fuel costs for a given amount of fuel to be consumed, taking advantage of spatial price differences.
