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.

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.

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.

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.

Development of the Capital Market in India - A Regulatory Perspective

Gupta Ramesh

Capital Markets are an important mobilizer of resources for the corporate sector. Investors' confidence is key to the healthy developments of capital markets, it is necessary that comprehensive and adequate laws exists to regulate security industry to protect investors interests and rights. The laws should also provide for an effective nodal regulatory agency to ensure fair play, discipline and integrity in the investment business. The paper review the current problems in working of the Indian capital markets and implementation of the security regulations. It suggests measures to improve efficiency of the markets, proposes a comprehensive regulatory framework and outlines the nature of implementing authorities. Further, it recommends a nodal regulatory authority independent of government interference which would be responsible for implementing the legislation. This agency would need to develop itself as a viable entity with its own infrastructure, trained manpower and professional work culture. For investors' protection, some additional measures like frequent disclosure of reliable information, creation of Investors Protection Fund, setting up of Investors Protection Advisory Council and promotion of local Investors' Associations are suggested. For quick redressal of grievances, an independent quasi-judiciary machinery is proposed. Since an individual investor is unable to take action because of disproportionate expenses involved in initiating the action, the laws should also provide for public interest litigation by investors association and other agencies on behalf of investors.

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.

Role of Futures Trading in Facilitating Commodity Exports

Naik Gopal and Aneja Ajay

In India, since its beginning in 1921 futures trading has been subjected to frequent intervention by the government in terms of allowing, banning and restricting its operation. As the debate on their utility for the economy as a whole, especially in terms of price stabilization, continues, the government is hesitant to encourage futures trading. The usefulness of futures markets are being reexamined in the light of its positive effects on international trade. Futures market seems to help exporters by way of reducing the risk of dishonor of contracts in the domestic market, reducing transaction cost due to liquidity and standardization, better market information and so on. However, unless the exporters are assured that in the long run they do not incur losses by participating in the futures market, they will not participate in the trading on price stabilization should not be negative. This study examined the issues of exporters' profitability from trading in castor seed futures and price stabilization effect to assess whether futures trading should be encouraged for enhancing exports. The results indicate that the castor oil exporters would not have incurred losses if they had consistently participated in the futures market. In fact they would have benefited by following certain trading strategies. The price stabilization test results also indicated that price stabilization effect is stronger than the destabilization effect. This is more so during high price years. These results indicate that futures trading can be beneficially used for export promotion.
