Understanding the structural characteristics of a firm's whole buyer–supplier network and its impact on international business performance

Amalesh Sharma, V. Kumar, Jun Yan, Sourav Bikash Borah, and Anirban Adhikary

Journal of International Business Studies

Building on the network theory and the concept of organizational ambidexterity, we investigate the impact of structural characteristics of a firm’s whole buyer–supplier network: network density, betweenness centralization, and average clustering coefficient on its international business (IB) performance. We also explore the moderating roles of average path length and PageRank centrality. Using a manually-collected dataset and a robust empirical methodology, we find that, while network density is negatively related, betweenness centralization and average clustering coefficient have an inverted U-shape and a U-shaped relationship with IB performance, respectively. We also find significant moderation effects, and, in the process, we show the economic importance of firms’ whole buyer–supplier network to their IB performance. We contribute to the international business and whole buyer–supplier network literature.

Leveraging service recovery strategies to reduce customer churn in an emerging market

Sourav Bikash Borah, Srinivas Prakhya, and Amalesh Sharma

Journal of the Academy of Marketing Science

Building on the properties of emerging markets, we investigate how a firm should align its service recovery strategies with different types of service failure to reduce customer churn in an emerging market. Using resource exchange theory and a multi-method approach, we show that the conventional wisdom related to service recovery needs to be reevaluated in emerging markets. Our results show that process failures lead to a higher likelihood of customer churn compared to outcome failures in emerging markets. Investigating service recovery mechanisms, we find that compensation is more effective in recovering from process failures than in recovering from outcome failures in emerging markets. Similarly, employee behavior has a stronger impact on mitigating the ill effects of process failures than those of outcome failures. The study contributes to the literature on service recovery and resource exchange theory and provides managerial insights for the effective management of customer churn due to service failures in emerging markets.

The goblet and two faces: Understanding transcendence and paradox from the perspective of Advaita Vedanta

Shiva Kakkar (FPM)

Human Resource Management International Digest

Purpose

Paradox theory looks at ambidexterity as a set of paradoxical yet interrelated demands. A form of response to such paradoxes is transcendence. Currently, there is limited understanding of the concept among researchers. Using concepts from the Indian philosophy of Advaita Vedanta, this paper aims to provide a deeper understanding of transcendence, highlight some of the epistemological challenges it presents and suggest ways in which the concept can be used by practitioners and ambidexterity researchers.

Design/methodology/approach

The paper uses concepts and theories from advaitic episteme to look at concepts of paradox and transcendence. The method of adhyaropa–apavada is introduced as a way to help individuals get a transcendental perspective of paradoxes. The application of the method is demonstrated using secondary data from published research on ambidexterity management.

Findings

It is postulated that transcendence is an “intuitive experience” born out of reflexive thinking. The dialectic of adhyaropa–apavada (affirmation followed by recension) is suggested as a pedagogical tool that can promote reflexive thinking.

Originality/value

The paper significantly adds to the theoretical understanding of paradoxes and transcendence in ambidexterity literature. The paper also makes a strong pedagogical contribution to literature by suggesting the dialectic of adhyaropa–apavada that can be used by managers to promote reflexive thinking among subordinates when faced with paradoxical situations.

An overlapping community detection algorithm based on rough clustering of links

Samrat Gupta and Pradeep Kumar

Data and Knowledge Engineering

The growth of networks is prevalent in almost every field due to the digital transformation of consumers, business and society at large. The unfolding of community structure in such real-world complex networks is crucial since it aids in gaining strategic insights leading to informed decisions. Moreover, the co-occurrence of disjoint, overlapping and nested community patterns in such networks demands methodologically rigorous community detection algorithms so as to foster cumulative tradition in data and knowledge engineering. In this paper, we introduce an algorithm for overlapping community detection based on granular information of links and concepts of rough set theory. First, neighborhood links around each pair of nodes are utilized to form initial link subsets. Subsequently, constrained linkage upper approximation of the link subsets is computed iteratively until convergence. The upper approximation subsets obtained during each iteration are constrained and merged using the notion of mutual link reciprocity. The experimental results on ten real-world networks and comparative evaluation with state-of-the-art community detection algorithms demonstrate the effectiveness of the proposed algorithm.

Understanding parental mediation of violent television commercials

Akshaya Vijayalakshmi, Russell Laczniak, and Deanne Brocato

Journal of Consumer Marketing

Purpose

This study aims to uncover in-depth examples of how emergent media affects parents’ views and socialization efforts. The study examines these views and efforts in the context of violent commercials.

Design/methodology/approach

The authors collected data for this paper using two studies. In Study 1, they collected data from the internet. Comments related to “violent ads” or “violent commercials” were collated and analyzed. For Study 2, they conducted in-depth interviews with mothers on their views on parental mediation and impact of media on their children.

Findings

The internet data helped develop a parental definition of violent ads and identify that parents lie on a continuum regarding their concerns about violent commercials. Further in-depth questioning of parents on the above finding led to the identification of four clusters of parents. “Media managers” attempt to control and restrict their child’s media environment while educating their child about the effects of violent commercials. “Enablers” spend abundant time co-viewing primetime TV while engaging their child in conversations on violence, but not on violent ads. To maintain harmony in the household, “Harmonizers” merely restrict viewing of violent commercials without educating their child about its effects. Finally, “Agent evaluators” are likely to co-view violent commercials, without discussing them with their child.

Research limitations/implications

First, several of the parental segments (media managers, enablers and harmonizers) tend to note some concerns with violence in advertising. Importantly, this concern for violence appears to be limited to gore and use of physical weapon. Second, while parents do not have homogenous views on violent ads, those who are concerned also have differing roots of concern. This influences their mediation efforts. Third, socialization is bi-directional at times.

Practical implications

Many parents do not approve are the use of physical violence, use of weapons and depiction of blood/gore even in ads for movies or videogames. Advertisers might be wise to avoid such content in ads directed to children. Second, if media and marketing managers could plan to sponsor TV shows (vs placing violent ads) that offer ad-free program time, parents might respond positively. Third, as socialization is bi-directional, advertisers could consider using ad scenarios where parents and children engage with the pros and cons of a certain product or content, thus enabling parent-child conversations to make an informed decision.

Social implications

Many parents notice violence in ads; policymakers could consider developing ratings for ads that consider the amount and type of violence while rating an ad. Second, a focus on increasing parental awareness on the harms of constantly exposing children to violent commercials might change the views of some parents who currently believe that a few or no violent commercials are being aired during children’s programs. Finally, parents envisage a greater role for media in their lives, and policymakers will have to suggest ways to effectively integrate media content in one’s lives rather than just suggest bans or restrictions.

Originality/value

The contributions of this paper include viewers’ (vs researchers’) definition of violent commercials, showcasing that parents are likely to manage media using new media options such as Netflix, and some parents are likely to co-create rules with their children.

The geography of medical travel in India: Differences across states, and the urban-rural divide

Sandip Chakrabarti and Aruna Divya T

Applied Geography

There is a large body of literature exploring spatial disparity in access to healthcare services, and the resultant geographic inequality in the demand for medical travel. We are, however, unaware of any such study conducted in India in the past. The transportation implications of inequitable healthcare access, therefore, remains unknown to Indian planners and policymakers. We use a unique dataset, the 2014–15 Domestic Tourism Expenditure survey conducted by the National Sample Survey Office, Ministry of Statistics and Programme Implementation, Government of India, to address this critical gap in the literature. We use trip-making information of 42,547 persons (13,525 urban and 29,022 rural residents) belonging to 28 Indian states in order to analyze the variation in individuals' medical trip destination choice, on average, across states. We analyze overnight trips (i.e., trips involving at least one night stay away from home) made for medical purposes only. Specifically, we isolate and compare the independent influence of state of residence (i.e., the state-effect) on residents' choice of within-district and out-of-state medical care location, after controlling for various personal and household factors that also govern choice. Additionally, we select a sub-sample of individuals who made out-of-state medical trips, and analyze state-level differences in the likelihood of long or >1500 km (vs. short or ≤1500 km) distance medical travel. We analyze urban and rural residents separately, and estimate a pooled model to explore intra-state urban-rural differences in medical trip destination choice. Our analyses reveal significant variation in urban and rural residents' destination choice for medical trips across India's states. We also find within-state urban-rural differences in destination choice to vary significantly across states. Our analysis provides new information on the geography of medical travel in India, underscoring the need for further research on the causes and consequences of the geographic disparity in healthcare access, and targeted action to improve healthcare access equitably across states. We expect our paper to stimulate further research to guide national and state health and transportation policies in India.

Forefather distribution in a variant of Galton-Watson branching process.

Arnab Kumar Laha and Sumit Kumar Yadav

Stochastic Models

In this paper, we consider a variant of a discrete time Galton–Watson Branching Process in which an individual is allowed to survive for more than one (but finite) number of generations and may also give birth to offsprings more than once. We model the process using multitype branching process and derive conditions on the mean matrix that determines the long-run behavior of the process. Next, we analyze the distribution of the number of forefathers in a given generation. Here, number of forefathers of an individual is defined as all the individuals since zeroth generation who have contributed to the birth of the individual under consideration. We derive an exact expression for expected number of individuals in a given generation having a specified number of forefathers. Using this exact expression, we provide a detailed analysis for a simple illustrative case. Some interesting insights and possible applications are also discussed.

Bilevel optimization based on iterative approximation of multiple mappings

Ankur Sinha, Zhichao Lu, Kalyanmoy Deb, and Pekka Malo

Journal of Heuristics

A large number of application problems involve two levels of optimization, where one optimization task is nested inside the other. These problems are known as bilevel optimization problems and have been studied by both classical optimization community and evolutionary optimization community. Most of the solution procedures proposed until now are either computationally very expensive or applicable to only small classes of bilevel optimization problems adhering to mathematically simplifying assumptions. In this paper, we propose an evolutionary optimization method that tries to reduce the computational expense by iteratively approximating two important mappings in bilevel optimization; namely, the lower level rational reaction mapping and the lower level optimal value function mapping. The algorithm has been tested on a large number of test problems and comparisons have been performed with other algorithms. The results show the performance gain to be quite significant. To the best knowledge of the authors, a combined theory-based and population-based solution procedure utilizing mappings has not been suggested yet for bilevel problems.

Supporting and sustaining state-initiated women's empowerment: Learning from a national programme in India

Ankur Sarin and Vijaya Sherry Chand

Journal of International Development

State-led women's empowerment initiatives are usually indifferent to the tensions between the processes of transformation they initiate at the grassroots and the intermediary support structures they create to sustain empowerment. Drawing on the experiences of Mahila Samakhya, a programme initiated by the Indian state in the late 1980s, we argue that the failure of the state to acknowledge the struggles of the intermediary layers to reconcile the social purpose of transformation with the economic logic underpinning organizational survival only leads to reinforcing a new form of ‘neo-liberal compatible’ governance. © 2019 John Wiley & Sons, Ltd.

Downstream electric utility restructuring and upstream generation efficiency: Productivity dynamics of Indian coal and gas-based electricity generators

Anish Sugathan Anish Sugathan, Deepak Malghan, S Chandrashekar, and Deepak K. Sinha

Energy

This paper investigates the producer-level temporal dynamics of total factor productivity and operational performance changes in coal- and gas-based generators during the 2000–20013 period of major structural reforms in the downstream utilities in India. The total factor productivity is estimated using a recently developed improvement in the Stochastic Frontier panel method that controls for time-invariant unobserved heterogeneity, and the productivity change is decomposed into components of changes in technology frontier, efficiency, scale and allocation. A unique dataset of station-level data for coal and gas plants, that represents about two-thirds of all power generation in India during this period, is constructed for the analysis. The study shows that while there is improvement in the coal generator productivity at the mean rate of 0.20% per year that converges towards a point of higher efficiency for most plants, the gas generators show a trend of stagnant efficiency and declining total factor productivity at the mean rate of −0.80% per year. Unbundling and multi-dimensional utility reform indices are significantly associated with improvement in thermal efficiency and capacity utilization for coal generators. In contrast, utility reforms shows no significant positive influence on gas generators, instead a decline in capacity utilization is observed following unbundling.
