Path Independence and Choice Acyclicity Property

Lahiri Somdeb

In this paper we study lower and upper approximations of choice functions and propose a necessary and sufficient condition for a choice function to have a path independent lower approximation. In an appendix to this paper we provide a simple proof of Theorem 2.10 in Deb (1983) in the case when the universal set is finite. In a final section of this paper, we characterize all batch choice functions using a choice acyclicity property.

Constraints to Export Growth in the Small Firm Sector

Sebastian Morris

Exports from small firms are analysed and the constraints in expansion and growth of exports from the sector are brought out. A large primary survey of over 1200 firms is used to bring out experiences of small firms. Small firms would have to have a major role in exports from India, because only they have access to the unorganised labour market. Principally, macroeconomic policy especially exchange rate, tariff and credit policies have discriminated against the sector. The adherence to orthodoxy has resulted not only in considerable under-performance of the sector and its exports, but also of the economy as a whole. Relaxation of the institutional and policy constraints in the expansion of manufactured exports should have been the topmost priority, but given the continued reign of orthodoxy this is most unlikely. As such labour absorption by the sector would hardly be able to go much beyond 4% per annum, and the envisaged growth of the economy at rates of 7% or more is hardly likely.

One and Two Facility Network Design Revisited

Sastry Trilochan

The one facility one commodity network design problem OFOC with flow costs considers the problem of sending d units of flow from a source to a destination where capacity is purchased in batches of C units. The two commodity problem TFOC is similar, but capacity can be purchased either in batches of C units or one unit. Flow costs are zero. These problems are known to be NP-hard. We describe an exact O(n33n) algorithm for these problems based on the repeated use of a bipartite matching algorithm. We also present a better lower bound of W(n2k*) for an earlier W(n2k) algorithm described in the literature where k = ëd/Cû and k* = min {k, ë(n-2)/2û }. The matching algorithm is faster than this one for k ³ ë(n-2)/2û. We next consider an extended formulation of the problem, describe an efficient heuristic based on this formulation, and use it to show that for problems with up to five nodes, the formulation guarantees integer optimal solutions. We also give an example of a six node graph for which the extended formulation has a fractional solution. Finally, we provide another reformulation of the problem that is quasi integral, i.e. every edge of the integer polytope is an edge of the polytope associated with the linear programming relaxation of the reformulation. This property could be useful in designing a modified version of the simplex method to solve the problem using a sequence of pivots with integer extreme solutions, referred to as the integral simplex method in the literature.

Identification of Best Practices: A Study of Passenger Car Dealers in India

Sastry Trilochan and Mukherjee Avinandan

Automobile manufacturers and car dealers entering fast growing, emerging markets often face several crucial decisions. A key question in this context is: what are the characteristics of an efficient dealer? In this paper, we identify best practices in dealer management in the Indian automobile industry. The research is based on a survey among dealers and manufacturers in India. We link dealer strategies to dealer performance, using Data Envelopment Analysis as a technique where elements of dealer strategy are treated as inputs, and performance parameters as outputs. Efficient dealers were identified based on this model. Three patterns or configurations of efficient dealers emerged: the laissez faire, where manufacturers leave dealers to function independently with minimum regulation or control, market leaders with high investments in facilities who are associated with high sales, and agile dealers with relatively low sales, low investments and high levels of training. Using regression, we also identified important factors that seem to lead to better performance. These factors were investments in sales and after sales facilities, dealer training, dealer expenditure on advertising and promotions, and dealer participation in decision making. The results also indicate that there is a need to benchmark distribution practices to help dealers improve their performance.

When Literacy Campaigns Gave Birth to a Women Movement: The Case of Jago Bahana in Dumka (Bihar)

Brij Kothari

Total and Post Literacy Campaigns have launched incidental processes of women's empowerment in almost every district that witnessed this uniquely Indian innovation. However, these processes have generally tended to fade with the campaigns' closure. This has prompted suggestions, that, if the incipient women's empowerment processes originating in the literacy campaigns are to become sustainable, they need to be linked to the women's movement(s). The central argument of this article is that while linkages with the women's movement(s) are desirable, they are not a necessary condition for sustainability, as demonstrated by the self-generated, self-sustained, and self-styled women's movement that was born from the literacy campaigns in Dumka, Bihar ((India). Jago Bahana (JB), continues to enhance its presence and power as a women's movement, in Dumka, even after the literacy campaigns that crated it have ended. The case of JB is discussed in depth with a focus on the processes that created it, its internal structure, and the activities that earned it legitimacy at every level of the district. Lessons for sustainable women's empowerment are drawn, relating to the role of a gender-aware district level bureaucracy, the exclusive space cared for women's participation, and the tangible nature of the benefits delivered to women and families.

Indigenous Voice: The Regressive Effects of Western Models on Organization Structure, Management Practices & Relationship Processes in Indian Organizations

Parikh Indira J

The decades of the nineties for the Indian organization have been both dramatic and traumatic. India has borrowed technology, organization structures and management practices from Japan and many countries of the West. The assumptions of how technology and management practices ought to work are anchored in their respective cultures. The operationalization of the technology and organization structures are through human resources of the organization who are anchored in the socio-cultural as well as organizational structures, roles and processes. This paper "Indigenous Voice: The Regressive Effects of Western Models on Organization Structure, Management Practices and Relationship Processes in Indian Organizations" explores the historical antecedents of the growth of Indian organizations, the processes of borrowings and adoptions of and adaptations to technology and organizational models. It also explores their impact on organization structure, management practices and relationships, the present status of Indian organizations, the images of the donors of technology and organization models as held by the manages and other employees and the internal dynamics and the reality of Indian organizations and its people. The paper then identifies some of the functional and healthy processes of Indian organizations which could revitalize and reenergize these organizations.

Same Language Subtitling: Literacy Development in India through Film Songs

Brij Kothari

India's efforts in basic primary and adult education are turning an increasing number of non-literates into semi- and neo-literates. But due to a serious lack of literacy skill practice opportunities, many relapse into illiteracy. Same Language Subtitling refers to the idea of subtitling television and/or film programmes in the "same" language as the audio (e.g., Hindi programmes subtitled in Hindi). This paper proposes the use of SLS in the enormously popular film-song-based programmes on state and private television networks, as a subliminal way to integrate literacy skill practice into people's everyday television viewing. Film songs are the core of Indian popular culture, offering a unique opportunity to strengthen audio-text associations. The main advantages, which do not exist in regular dialogue, is that songs are inherently repetitive and people subconsciously anticipate song phrases. An appropriate format for subtitling song-programmes was arrived at Sample SLSed songs were shown to impromptu audiences in Ahmedabad city slums, at the railway station, and some villages in Gujarat. Overt evidence of reading, such as lip movement, was recorded on video camera. The subtitling format chosen drew few objections,; interference with the visuals, if any, was not problematic. Audience feedback confirmed that SLS invites reading. The technique does not compromise entertainment but enhances it, thus, making it useful for both the literate and the partially literate. Enhanced entertainment results from SLS because it offers viewers an opportunity to sing along and know the song lines. SLS gives definition to poorly audible sound common in group viewing situations and/or a noisy ambience. The deaf and hearing impaired would benefit especially. Considering the social and entertainment gains, SLS is extremely inexpensive and easily implemented on television and films.

Computer Simulation of Hospital Systems

K. V. Ramani

Hospital Management is an area of considerable importance to governments' health authorities and the general population. Governments all over the world are concerned about providing quality health care to their people. The situation has become very critical recently in the light of rapidly increasing costs for medical care and the potentially declining levels of service. Hence there is an urgent need to study hospital management systems in detail in order to suggest cost effective solutions for service quality improvements. In our exploratory research study, we have chosen to focus on the quality of outpatient services at CMC Hospital, Vellore. In this report, we discuss the design and development of a computer simulation model to analyse the existing outpatient system and to evaluate alternatives for CMC Hospital to improve the quality of outpatient services.

A Study on the Personality Profile of Middle Managers: The Indian Experience

Parikh Indira J, Singh Nimrat, and Shah Nayana

In the context of transformations taking place in the environment, organizations are initiating major changes in their structure, design and human processes. These changes generate a great deal of anxiety and apprehension amongst different levels in the cadre. It appears that the middle level managers in the organization are affected the most through these changes. The top levels and the lower most levels are becoming more powerful whereas the middle levels are questioning their space and location in the organization. An action research study was undertaken to get into the universe of this level of managers and get a feel of how they perceive and respond to these changes. This study utilized a projective technique (the Thematic Apperception Test) to unfold the personality traits of these managers which were then linked to their response patterns in social and organizational contexts. An effort was made to move from a micro to a macro level. This work was undertaken in groups of 12-15 middle managers across different organizations. Three day workshops were held to explore and enlarge the concepts of job, task, role, hierarchical relationships, membership in a group and professionalization of systems. These workshops facilitated a look into the self in the context of the external environment. The aim here, was to generate greater ownership and enhance effectiveness among the middle managers. Having explored the universe of the managers through their stories and the group interactions that took place, some specific traits and experiences got revealed. These are grouped into specific themes like (a) individual's definition of self, work and social roles; (b) individual's experience with authority and relationships; (c) individual as a group member; and (d) individual's experience with structure, system and processes. The external and internal influences on a manager's role-taking processes are also discussed in the paper. These findings have relevance for the human resource professional in designing such systems and structures keeping in view the socio-cultural context, the dreams, aspirations and ambitions of this group and the present reality of the organization and the environment.
