Managerial Roles and Interfaces: Some Organizational Issues and Implications through Thematic Apperception Test

Parikh Indira J and Kollan Bharti

Indian organizations are encountering transformations within the organization and in the external-both national and global environment. In this era of rapid transformations Indian managers need assess their role taking and interfaces across the organization. This study is based on 30 workshops arising out of diagnostic studies of the organization and its resultant identification of developmental inputs. The organizations were set on a path of growth and a commitment to professionalize their existing managers so that the organization could become vibrant and dynamic. The present paper emphasis on the content of the stories, situations involving mostly interpersonal relations, Such as father-son or superior and subordinate are examined for the feelings and subsequently, what actors are being triggered off by the interface. The paper also explores the manager's perception of the job, role, task and performance. Based on the content analysis of each story, the paper investigate how the manager take's initiatives to accept the challenges of their jobs and subsequently, adding new dimensions to their role.

An Efficient Algorithm for Frequent Pattern Mining for Real-Time Business Intelligence Analytics in Dense Datasets

Rajanish Dass

Finding frequent patterns from databases has been the most time consuming process in data mining tasks, like association rule mining. Frequent pattern mining in real-time is of increasing thrust in many business applications such as e-commerce, recommender systems, and supply-chain management and group decision support systems, to name a few. A plethora of efficient algorithms have been proposed till date, among which, vertical mining algorithms have been found to be very effective, usually outperforming the horizontal ones. However, with dense datasets, the performances of these algorithms significantly degrade. Moreover, these algorithms are not suited to respond to the real-time need. In this paper, we describe BDFS(b)-diff-sets, an algorithm to perform real-time frequent pattern mining using diff-sets and limited computing resources. Empirical evaluations show that our algorithm can make a fair estimation of the probable frequent patterns and reaches some of the longest frequent patterns much faster than the existing algorithms.

Are You Risk Averse Over Other People's Money?

Chakravarty Sujoy, Harrison Glenn W, Haruvy Ernan E, and Rutstrom Elisabet E

Abstract. Decisions with uncertain outcomes are often made by one party in settingswhere another party bears the consequences. Whenever an agent is delegated tomake decisions that affect others, such as in the typical corporate structure, does theagent make decisions that reflect the risk preferences of the principal? We examinethis question in the simplest possible setting using controlled laboratory experiments.We find a remarkable result: when an individual makes a decision for an anonymousstranger, he tends to exhibit less risk aversion. This reduction is relative to his ownpreferences, and also relative to his belief about the other's preferences. This resulthas significant implications for the design of contracts between principals and agents.

What's Keeping the Apples Away? Addressing the Market Integration Issue

Satish Y. Deodhar

Apples have been grown in India for a century. At present apple production exceeds 1.4 million tonnes a year. Still, there are wide variations in the apple prices across the country. We test the price data for market integration using cointegration and error correction methodology. Delhi, the major wholesale market for apples, does not seem to influence other markets. Mumbai market does influence Bangalore market, although with about a two week lag. Absence of integration can be attributed to traders from southern region bypassing the Delhi wholesale market, cascading effect of trader margins at various distribution points, absence of competition to agricultural produce marketing committee markets, and, inadequacy of road and cool chain infrastructure.

A Process Oriented Approach to Waiting Line Management in a Large Pilgrimage Center in India: A Case Study

N. Ravichandran and Rao Subba I V

This article documents an innovative approach to manage waiting line in the largest pilgrimage center in the world. By a judicious combination of process orientation and advances in Information Technology, the pilgrimage center's management has been able to dramatically change the pilgrims waiting experience. The pilgrimage location under study is Tirumala located in Andhra Pradesh state in India. The number of visitors to this important location has been steadily increasing over time. As of 2005, the location attracted approximately 16 million visitors a year. The primary objective of a pilgrim visiting Tirumala is to have darshan of the principle deity in the temple. The secondary objectives include tonsure (shaving head as a mark of respect), offering donations, prasad collection, local sight seeing and shopping. The immense popularity of the temple and its location poses significant challenges to the management of the system. This temple is a tradition bound Institution. Therefore, some alternatives to resolve pilgrim waiting time are feasible and some are not. There are some hard constraints which may not stand the test of logic. The ability to manage the traffic volume is a function of processing rate (darshan duration) at the temple and darshan time available per day. This case study is an example of improving operational effectiveness by using formal management methods in addressing an important real life problem in an under researched area.

Trade Cost, Trade Policy and Trade Volume: A Study of Indian Apple Market

Satish Y. Deodhar

Trade Cost form a significant part of moving goods from producer to consumer. These cost are particularly high in developing countries. As a representative country, we look at India's apple trade. Although tariff on apple imports is high, local distribution cost are much higher. While Tariff reduction will somewhat benefit the consumer, liberalization that promotes lowering of traders' margins may facilitate high-volume, low-margin trade. Trade cost may come down if uncertainty regarding phytosanitary norms goes down and infrastructure investments in cold chain and retails chains pick up. Ceteris paribus, it is expected that demand for imported apples could reach 70,000 tonnes per year in a decade.

Format Choice of Food and Grocery Retailers

Piyush Kumar Sinha, Mathew Elizabeth, and Kansal Ankur

Format choice is recognized as a cognitive process. Like any other purchasing decision format choice also is an information processing behavior. A store is chosen based on the confidence that the customer has regarding the store; about the nature and quality of product and service he will receive. In Indian scenario formats have been found to be influencing the choice of store as well as orientation of the shoppers (Sinha and Uniyal, 2005). This study seeks to analyze the various factors influencing decision making process of customers in choosing a store format. A full-profile* procedure was used for the Conjoint Analysis in this study. The exploratory study brought out five different formats that existed in the food and grocery sector. With this it also identified combinations of the seven parameters have given rise to some generic retail formats. It also helped identifying the important factor set which affects consumer format choice decisions. The findings also provide details useful for retailers in designing an efficient retail package to offer their customers. * Full-profile conjoint analysis has been a popular approach to measure attribute utilities. In the full-profile conjoint task, different product descriptions (or even different actual products) are developed and presented to the respondent for acceptability or preference evaluations. Each product profile is designed as part of a fractional factorial experimental design that evenly matches the occurrence of each attribute with all other attributes. By controlling the attribute pairings, the researcher can estimate the respondent's utility for each level of each attribute tested.

Health System in India: Opportunities and Challenges for Improvements

K. V. Ramani and Dileep Mavalankar

Health and Socio-economic developments are so closely intertwined that is impossible to achieve one without the other. While the economic development in India has been gaining momentum over the last decade, our health system is at crossroads today. Even though Government initiatives in public health have recorded some noteworthy successes over time, the Indian health system is ranked 118 among 191 WHO member countries on overall health performance. Building Health Systems that are responsive to community needs, particularly for the poor, requires politically difficult and administratively demanding choices. Health is a priority goal in its own right, as well as a central input into economic development and poverty reduction. Health sector is complex with multiple goals, multiple products, and different beneficiaries. India is well placed now to develop a uniquely Indian set of health sector reforms to enable the health system in meeting the increasing expectations of its users and staff. Managerial challenges are many to ensure availability, access, affordability, and equity in delivering health services to meet the community needs efficiently and effectively. In this working paper, we describe the status of our health system, discuss critical areas of management concerns, suggest a few health sector reform measures, and conclude by identifying the roles and responsibilities of various stakeholders for building health systems that are responsive to the community needs, particularly for the poor.

Privacy Violation and Detection Using Pattern Mining Techniques

Bhattacharya Jaijit, Rajanish Dass, Kapoor Vishal, Chakraborti Debamitro, and Gupta S K

Privacy, its violations and techniques to bypass privacy violation have grabbed the centre-stage of both academia and industry in recent months. Corporations worldwide have become conscious of the implications of privacy violation and its impact on them and to other stakeholders. Moreover, nations across the world are coming out with privacy protecting legislations to prevent data privacy violations. Such legislations however expose organizations to the issues of intentional or unintentional violation of privacy data. A violation by either malicious external hackers or by internal employees can expose the organizations to costly litigations. In this paper, we propose PRIVDAM; a data mining based intelligent architecture of a Privacy Violation Detection and Monitoring system whose purpose is to detect possible privacy violations and to prevent them in the future. Experimental evaluations show that our approach is scalable and robust and that it can detect privacy violations or chances of violations quite accurately.
