Prevention of and interventions in workplace bullying: A global study of human resource professionals' reflections on preferred action

Denise Salin, Renee Cowan, Oluwakemi Adewumi, Eleni Apospori, Jaime Bochantin, and Premilla D'Cruz

The International Journal of Human Resource Management

The aim of this study was to analyze Human Resource Professionals’ reflections on the prevention of and intervention in workplace bullying across different countries. More specifically, the study sought to identify what actions were, in the experience of human resource professionals, best to prevent and intervene in bullying and uncover organizations’ motives for engaging in such work. The study was conducted through semi-structured interviews (n = 214) in 14 different countries/regions, representing all continents and all GLOBE cultural clusters. Qualitative content analysis was performed to analyze the material. The findings indicate that bullying was largely conceptualized as a productivity and cost issue, and that was largely driving efforts to counter bullying. Training and policies were highlighted as preferred means to prevent bullying across countries. In contrast, there were large national differences in terms of preferences for either disciplinary or reconciliatory approaches to intervene in bullying. This study advances our understanding of what human resource professionals consider preferred ways of managing workplace bullying, and adds to our understanding of cross-national differences and similarities in views of this phenomenon. As such, the results are of relevance to both practitioners and scholars.

Robot-storage zone assignment strategies in mobile fulfillment systems

Debjit Roy, Shobhit Nigam, Rene de Koster, I.J.B.F. Adan, and J.A.C. Resing

Transportation Research Part E: Logistics and Transportation Review

The robotic mobile fulfillment system (MFS) is widely used for automating storage pick and pack activities in e-commerce distribution centers. In this system, the items are stored on movable storage shelves, also known as inventory pods, and brought to the order pick stations by robotic drive units. We develop stylized performance evaluation models to analyze both order picking and replenishment processes in a mobile fulfillment system storage zone, based on multi-class closed queueing network models. To analyze robot assignment strategies for multiple storage zones, we develop a two-stage stochastic model. For a single storage zone, we compare dedicated and pooled robot systems for pod retrieval and replenishment. For multiple storage zones, we also analyze the effect of assigning robots to least congested zones on system throughput in comparison to random zone assignment. The models are validated using detailed simulations. For single zones, the expected throughput time for order picking reduces to one-third of its initial value by using pooled robots instead of dedicated robots; however, the expected replenishment time estimate increases up to three times. For multiple zones, we find that robots that are assigned to storage zones with dedicated and shortest queues provide a greater throughput than robots assigned at random to the zones.

Racial/ethnic parity in disciplinary consequences using student threat assessment

Dewey Cornell, Jennifer Maeng, Francis Huang, Kathan Shukla, and Timothy Konold

School Psychology Review

School psychologists are frequently called upon to assess students who have made verbal or behavioral threats of violence against others, a practice commonly known as threat assessment. One critical issue is whether the outcomes of a threat assessment generate the kind of racial disparities widely observed in school disciplinary practices. In 2013, Virginia became the first state to mandate threat assessment teams in all public schools. This study examined the disciplinary consequences for 1,836 students who received a threat assessment in 779 Virginia elementary, middle, and high schools during the 2014–2015 school year. Multilevel logistic regression models found no disparities among Black, Hispanic, and White students in out-of-school suspensions, school transfers, or legal actions. The most consistent predictors of disciplinary consequences were the student's possession of a weapon and the team classification of the threat as serious. We discuss possible explanations for the absence of racial/ethnic disparities in threat assessment outcomes and cautiously suggest that the threat assessment process may reflect a generalizable pathway for achieving parity in school discipline.

Hesitant information sets and application in group decision making

Manish Aggarwal

Applied Soft Computing

The recent information set theory provides a useful mechanism to represent an agent’s perceived information values. However, often a decision-maker (DM) considers multiple evaluations for the same information source value. To this end, we extend the recent information set as hesitant information set (HIS). It gives the multiple perceived information values, corresponding to an information source value. In the context of multi-attribute decision making, HIS represents a set of different possible subjective utilities that an agent may perceive as an evaluation of an alternative-attribute pair. The basic operations, and properties of HIS are investigated. A few information measures based on HIS are presented. Besides many illustrative examples, a real application in group multi attribute decision making problem is included.

Generalized attitudinal Choquet Integral

Manish Aggarwal

International Journal of Intelligent Systems

Attitudinal Choquet integral (ACI) extends Choquet integral (CI) through a consideration of a decision-maker's (DM's) attitudinal character. In this paper, we generalize ACI, and the resulting operator is termed as generalized ACI (GACI). GACI adds to the efficacy of the ACI in the representation of a DM's unique and complex attitudinal character. It also generates a vast range of exponential ACI operators, such as harmonic ACI, ACI, quadratic ACI, to name a few. We further present induced GACI to consider additional information that may be associated with the arguments of aggregation. The special cases of the proposed operators are investigated. The usefulness of the proposed operators in modelling human decision behavior is shown through a case study.

Decision aiding model with entropy-based subjective utility. Information Sciences

Manish Aggarwal

Information Sciences

An entropy-based method is presented to model a decision-maker’s (DM’s) subjective utility for a criterion value. The proposed method considers distribution of all the values that the criterion takes for the given set of alternatives. Based on the utility so modeled, and and the DM’s attitudinal character, a multi criteria decision aiding (MCDA) approach is developed to find the best alternative. The proposed method and the approach are applied in a real car selection case-study.

Constitution, Supreme Court and Regulation of Coal Sector in India

M P Ram Mohan and Shashikant Yadav

NUJS Law Review

The paper maps four decades of coal sector litigation before the Supreme Court of India and draws a narrative on the constitutional contestation and the legal position as it stands today. Coal is one of the most important minerals from an economic perspective, accounting for over sixty percent of India’s energy requirement. The Constitution of India empowers both the Centre and states with legislative powers relating to regulation and control over mines and minerals, including coal. The coal sector has witnessed highly contested and protracted litigation with respect to law-making powers between the Centre and state governments, and this has impacted business and society in many ways. Through a mapping of judicial decisions of Supreme Court, the contested nature of governance of Indian coal sector is detailed in the paper. The Court has consistently maintained a greater responsibility of regulating mines and mineral development on the Union government. However, advocating sustainable use of coal resources, the Court emphasised that the regulatory power vested with Centre and states must have its basis on public interest and coal must be treated as a material resource of the community.

Which interpretational route will the Supreme Court of India follow when faced with the contentious civil liability for Nuclear Damage Act, 2010

M P Ram Mohan

Statute Law Review

The Civil Nuclear Liability for Damages Act of India enacted in 2010 has been a matter of concern to international suppliers and vendors. This is due to the perceived deviation of the law from the principle of legal channelling of liability (to the operator) which is at the heart of international nuclear liability jurisprudence. Specifically, this notion arises from allowing recourse to suppliers under outside of the circumstances mentioned in the Annex of the Convention for Complementary Compensation. Sections 17 and 46 which embody this notion are subject to different interpretations, some of them implying the compliance of the Indian regime with the international nuclear liability regime and many others equally suggest otherwise. In 2015, Government of India through a detailed Frequently Answered Questions clarified the nature and meaning of these sections. However, interestingly, there are two cases pending before Supreme Court of India contesting the constitutionality of the legislation in which these two specific provisions are also disputed. The article attempts to explain and resolve the ambiguity through a study of Supreme Court’s approach to statutory interpretation. I undertake an analysis of the reasoning given under the 2015 FAQ in the light of the disputed Sections 17 and 46 and bring out a probable prediction of Court’s interpretation of the Sections of the Act.

Determinants of conflict in channel relationships: A meta-analytic review

Dheeraj Sharma and Biswajita Parida

Journal of Business and Industrial Marketing

Purpose 

The advent of the internet, digitization and e-commerce has changed the definition of business territory, re-invented direct selling, eradicated middle men and brought the customers and sellers closer. These changes in the business scenario must have had an impact on the intensity and nature of channel conflict which needs to be inspected to structure better channel relationship strategies in the changing context. This paper aims to attempt a systematic investigation into the determinants of channel conflict in today’s context and proposes a composite model by reconciling the research so far in the domain of channel relationships.

Design/methodology/approach

An exhaustive search was carried for extant research finding in the channels resulting in the identification of 284 research papers beyond the meta-analysis by Geyskens et al. (1999). The next step was to manually scan through each of these papers to identify the studies which involved quantitative analysis including measures of association such as correlations related to conflict and the determinants of conflict. This led to the finalization of 36 research papers for the meta-analysis.

Findings 

This study proffers a model that illustrates ranking of major determinants of channel conflict. The results of the study suggest that determinants can be categorized into three major domains: organizational, interpersonal (communication, cooperation, relationship activities and opportunistic behaviour) and environmental factors (environmental volatility, competitive intensity and product or market volatility).

Research limitations/implications 

The analysis is based on static data in the sense that the correlations do not reflect supplier-channel member interactions in specific conflict situations. It may be argued that conflicts ultimately occur among firms/businesses run by individuals and individual traits may also impact the formation and resolution of conflict. Further, the quality of the measures capturing the constructs was not investigated in many studies. Final limitation pertains to the measurement of conflict. Conflict may not have been measured in a uniform manner in each of the studies analysed. As this study has evaluated extant research through a meta-analysis, it was not possible to identify the correlations between the determinant variables and the three factors (or constructs).

Practical implications

This study reconciles different research streams in this domain with the visualization of the composite model. It presents a quantitative analysis of the correlations of the determinants of conflict with channel conflict holistically. It creates a base through the composite model to carry forward the academic discussion in this domain holistically. It aims to be a ready reference for understanding the antecedents of conflict along with their significant correlations to enable prioritization of their channel strategies.

Social implications 

This meta-analysis and the suggested model that may be of use to practitioners in terms of prioritizing their activities to reduce channel conflicts through pre-emption. It is hoped that this study enhances the extant understanding of the determinants of channel conflict considerably based on the presented composite model. The results may assist to resolve channel conflicts, create channel synergies, identify optimal channel mix, reduce channel costs, increase channel efficiency and build partnerships in the changing business scenario.

Originality/value 

A holistic view of the determinants of conflict would be of enormous use to practitioners and academics alike. Hence, a detailed study is required to enlist and categorize the determinants causing conflict in channels so that an attempt can be made to resolve channel conflict for better performance of the firms. This meta-analysis study is an attempt to fill this major gap in research in this domain to quantitatively analyse the major determinants of channel conflict on the basis of analysis of research work over the past 15 years

Conceptualization to amendment: Kakinada as a smart city

Lavanya Chintagunta, Priyanshu Raj, and Sundaravalli Narayanaswami

Journal of Public Affairs

Urbanization is globally rampant; in developing countries such as India, it is driven in a phenomenal pace by an aspiring, young society and ambitious state policies to achieve a competitive space in global economy. “Smart cities” is a new-age term coined specifically to control, monitor, measure, and evaluate our urban growth, in a way to understand how conducive are our cities for running businesses. Global borders are diminishing, and world-wide economies compete on multiple dimensions in a level playing field to participate and prosper in global markets. Cities are centers of economic activities, and the economic growth of a country largely depends on safe and supportive cities. Therefore, the need for smart cities is not difficult to establish. The more difficult questions are, “do we really know what a smart city is?” or “what are the elements that go into making an existing city smart?” Such questions are pertinent and timely. This paper attempts to answer these questions in a descriptive manner based on theoretical and empirical observations. We adopt an integrative approach of design conceptualization, policy building, and framework development, substantiated using an Indian city, namely, Kakinada in Andhra Pradesh State as an illustrative case.
