Novel Features for Review Helpfulness Prediction

Srikumar Krishnamoorthy

Online reviews play a critical role in customers purchase decision making process on the web. The online reviews are often ranked based on user helpfulness votes to minimize the review information overload problem. This paper aims to study the factors that contribute towards helpfulness of online reviews and build a predictive model. It introduces a set of novel features for predicting review helpfulness. The proposed model is validated on two real-life review datasets to demonstrate its utility. A rigorous experimental evaluation also reveals that the proposed linguistic features are good predictors of review helpfulness.

Impact of Store format on Shopping Involvement

Piyush Kumar Sinha and Dwarika Prasad Uniyal

Store formats exist in three forms of convenience, variety and experience. Shopping involvement tends to change across these formats. This current study (a) establishes the role of store formats on shopping involvement, (b) understands the change in the nature of involvement as the shopper moves to an experience store from a variety or a convenience store format, and (c) measures shopping involvement as different from purchase involvement or purchase-decision involvement. A 3 X 3 factorial design was created using the three formats and three levels of extent of information search representing different buying decisions. Participant observations at different formats were carried out, which was followed by in-depth interviews to understand the motivations and gratifications with regard to shopping and store formats. A new scale to measure Shopping Involvement was developed as different from purchase and purchase-decision involvement.

The study found that store formats impacted shopping involvement levels. The convenience format showed a lower level of involvement compared to other formats. However, there was no significant difference between the involvement levels of the variety store format and experience store format. The study showed that the expressive aspect of involvement became more prominent in experience store, while the functional involvement did not increase to the same extent. Shopping involvement in each of these formats also varied with the extent of information search. Retailers would benefit by adopting in-store activities that enhance involvement for the format used. They need to provide the correct type and amount of increase information to the shoppers for better shopping experience and building loyalty.

Measuring and Managing Institutional environment of Institutes of Professional Education

T. V. Rao and Siddhartha Saxena

Questionnaire surveys of perceptions of institutional environment have been found to be a good diagnostic tool to facilitate self-renewal, leading to effective management of institutions of Higher education. Normally, such tools are developed by interviewing multiple stakeholders (faculty, students, staff, etc.). By now, a number of tools have been developed and used. This paper presents four such tools that have been used extensively as diagnostic tools. One of them was developed to predict the adoption of innovations in engineering colleges and polytechnics. The second one was developed as a part of the self-renewal effort of one of the institutes of professional education and used to bring about change. The third one was developed using the Stern's framework based on Henry Murray's need-press model, which attempts to study student preference for activities or student interests (needs) and correlate them with corresponding Institutional environment (press) as perceived by the students. The questionnaires have been found to give more useful data about institutions, in addition to what the theoretical models offer. In using these tools, the authors promote a collaborative approach of Institutions based in the same location or managed by the common stakeholders of these institutions for bench marking, self-renewal and improvements.

Impact of interconnectedness of organizations on agility: A multi-theoretical perspective

Atul Arun Pathak

This paper conceptually explores the impact on the strategic agility of an organization due to it being a part of an inter-connected network of organizations. Organizations need to be strategically agile to respond to the challenges posed by dynamic environments. Existing literature has highlighted that today's organizations are more interconnected with each other than ever before in history. Also researchers are unanimous in their opinion that today's organizations face increased environmental dynamism. However, literature has not explored the relationship between organizational agility and inter-connectedness of organizations in a network. The focus of this paper is to bridge this gap by conceptually exploring whether an organization that becomes part of a network has the freedom and flexibility to evolve its own strategies, have an independent (of the network) understanding of the environmental changes, and even move from one network to another easily and without friction. The paper is based on network theory, resource dependent view and transaction cost theory.

When are Rewards Bad for Creativity? Examining the Role of Leadership and Integrated Extrinsic Motivation

Vishal Gupta

The relationship between common creativity antecedents and creative performance is seldom clarified and the assertion that employee attitudinal and work environment factors spur creative performance has rarely been tested. The present study adopts an individual level of analysis and investigates the association between leader behaviors, employee extrinsic motivation, creative performance behaviors and creative performance in the Indian R&D context. Data were collected using a survey questionnaire from 493 scientists working in 11 government-owned R&D laboratories of India and structural equation modeling was used to test the hypothesized relationships between the study variables. The study found evidence for the mediating role of employee integrated extrinsic motivation for the relationship between leadership and creativity (behaviors as well as performance). Building on the foundations of organismic integration and self-determination theories, the study shows that extrinsic motivation is positively related to creativity when the value of rewards is integrated to one's sense of self. Extrinsic motivation, otherwise, was found not to be related to creativity. Supervisory leadership was shown to be positively related to employee integrated extrinsic motivation. Thus, the study also provides an insight into the underlying process through which leaders can impact employee creativity at workplace. Implications for theory and practice are discussed.

A Method for Retail Product Selection using Data Mining

Srikumar Krishnamoorthy

Product assortment planning is considered as one of the important problems in the retail business. Traditional approaches to product selection in the assortment are largely based on individual product popularity or margins. More recent research works in the literature utilize the cross selling potential of products to improve profitability of the overall assortment. This paper builds on the extant literature and proposes a new product selection method for assortment planning. The proposed method makes use of association rule mining for better assortment planning. Our method is evaluated on a real-life retail dataset and the results are found to be quite promising. A detailed comparative evaluation and sensitivity analysis is also presented to demonstrate the utility of the new method.

Online Retailing Paired with Kirana – A Formidable Combination for emerging Markets

Piyush Kumar Sinha, Srikant Gokhale, and Saurabh Rawal

The World Wide Web was launched in 1991 by Tim Berners Lee and shortly after that, in 1994, Pizza Hut delivered its first pizza after receiving an online order. Electronic commerce is one of the boons of internet and the one that is speculated to alter how businesses will grow in the competitive world. India stands third in the world with over 130 million internet users. This has positively shaped the growth of electronic commerce in the country, from booking tickets to buying clothes to paying bills. Four major factors have advocated the growth and expansion of electronic commerce in India. First and foremost is the rapid penetration of technology, be it the broadband or the smart phones or online banking, has empowered the consumers to access the World Wide Web very easily.
Previous research has also highlighted how this impact of internet penetration is magnified specifically in the emerging economies. Second is the fast adoption of the online medium by every major brand as a part of their sales as well as the marketing strategy. Large retailer have also opened stores in the virtual space. The third factor is the convenience consumers derive through online shopping. More and more members of a typical Indian family are joining the workforce which leaves little time regular shopping errands. Consequently people have shifted to buying items online and this is further facilitated by services like cash-on-delivery, buy-back policies and many more. Finally growing real estate prices and low penetration of large format retailing have been indicating for a need to innovate to increase business.
In the light of the convenience provided by online and the omnipresent Kirana (mom-and-pop equivalent) stores, it is proposed that these two would be the dominant formats of retailing as a mix of brick and click models.

Cost and Benefit of Disinflation Policy in India

Ravindra H. Dholakia

Current monetary policy stance is based on assertions that there is no trade-off between inflation and growth and that disinflation will result in more growth. Present study examines recent empirical evidence on India for the direction of causality for growth and inflation, and short-run costs and long-run benefits likely for the deliberate policy of disinflation. There is no support for the first assertion because the regular trade-off does exist in India imposing substantial short-run costs for deliberate disinflation. There is a stronger evidence for causality from growth to inflation, but the reverse causality cannot be ruled out. Disinflation may result in the gain in long-run growth after 4 to 5 years. Under such conditions, RBI should hold nominal growth of money supply and allow supply side policies by the government to bring down the inflation.

Urban – Rural Income Differential in Major States: Contribution of Structural Factors

Ravindra H. Dholakia, Manish Pandya, and Payal M. Pateriya

In this paper, we have attempted to estimate the urban-rural income differential (URID) for 15 major states based on readily available data on GSDP by sectors, population and employment by sectors and urban-rural residence. There are three components of the URID, viz., worker population ratios (WPR), employment structure and labor productivity by sectors in urban and rural areas. We are unable to estimate the labor productivity differentials at the state level, but the other two factors are considered and the floor estimate for the URID is obtained for the 15 states in the four base years. Moreover, it is also shown with the help of the estimates available at the All India level that out of the three factors, employment structure is the most dominant one to determine URID and that the component of productivity differential is not very high. Assuming the same extent of the component of productivity differential for each state as for the country, estimates of the URID in the major states for the three base years are derived. We have also attempted an estimate of the URID for the country and the states in the likely base year of 2011-12 with corresponding urban and rural per capita incomes.

Multi-Period Facility Location Problem with an Uncertain Number of Servers

Amit Kumar Vatsa

We study the problem of allocating doctors to primary health centers. We model the prob-
lem as a multi-period uncapacitated facility location problem under uncertainty. The problem
is unconventional in that the uncertainty is in the number and period of availability of doctors.
We use a minmax regret approach to solve the problem. We present solution techniques using
local search and tabu search and compare our solutions with optimal solutions obtained using
commercial solvers. We see that one of our tabu search algorithms is faster and yields optimal
solutions in the problems we tested on.
