Project Nirman: The way ahead

Anamika Sinha, Biju Varkkey, and Priyanka Dave

South Asian Journal of Business and Management Cases

Project Nirman by SAATH, a Gujarat-based NGO, aimed at empowering and training migrated workmen as masons, carpenters and electricians as per industry requirements. The project was funded by Bosch India Foundation. Although all aspects of the pilot project were successfully tested for sustainability, continuous funding remained a challenge. The project’s protagonist wanted to upscale operations but was facing a dilemma. While exploring options for sustainability on a continuum of dependency to complete self-sufficiency, the protagonist became increasingly aware of roles and identities of each partner in such alliances.

Some peripheral dilemmas like challenges in identifying a socially relevant project, upscaling the pilot project, identifying team capabilities for growth and need for value integration by different stakeholders for desired growth were noted. This case closes by questioning on how strategic alliances should be made so that the four partners — government, community, Non-government Organization and corporate — learn to coexist with mutual respect.

Energy balance of Indian villages: A case study of seven villages

Amit Garg, Jaypalsinh Chauhan, and Abha Chhabra

Journal of Operation and Strategic Planning

This paper estimates the rural energy balance of 7 Indian villages of different agro-climate zones. This was done through primary survey of households in each village covering energy consumption, production, export, import and stock change across Crop, Livestock, Industry/Trade, Tree outside forest/plantations and Residential Sector. An energy flow model was created to capture all the various energy flows at household levels. Two villages are showing Negative annual energy balance—one is the desert village of Gujarat state and another is a tribal village of Mizoram state. All other villages were found to be energy positive mainly due to high forest density and high crop yields.

Investigating the impact of workforce racial diversity on the organizational corporate social responsibility performance: An institutional logics perspective

Amalesh Sharma, Aditya Christopher Moses, Sourav Bikash Borah, and Anirban Adhikary

Journal of Business Research

Racial diversity is considered an integral part of the business world. The extant literature has focused on the effect of racial diversity on a firm's financial performance and presented mixed findings. Building on the institutional logics lens and using a sample of 204 firms belonging to 9 industries and spread across 21 countries for a period of six years, we explore the impact of workforce racial diversity on the Corporate Social Responsibility Performance (CSRP) of a firm. In addition, we also investigate the contingency effects of a firm's absorptive capacity and slack resources on the proposed relationship. Using a seemingly unrelated regression model and accounting for endogeneity, we find that racial diversity has an inverted U-shaped relationship with a firm's financial and social performance and has a U-shaped relationship with its environmental performance. We also find significant moderating effects. Thus, we contribute to the theory and practice in the field.

Managing children's internet advertising experiences: Parental preferences for regulation

Akshaya Vijayalakshmi Meng‐Hsien (Jenny) Lin and Russell N. Laczniak

Journal of Consumer Affairs

Recent research suggests that children are spending a significant amount of time on the Internet which increases their exposure to subtle, engaging, and interactive ads. As a result, policy makers have developed regulations intended to empower parents to manage their children's exposure to Internet advertising. However, prior research has not examined parental perceptions of these regulations. This article aims to identify (1) parents' regulatory preferences regarding children's exposure to Internet advertising and (2) whether (and how) parents' locus of control (LOC) drives their regulation preferences. Findings reveal that internal-LOC parents prefer parental responsibility while external-LOC parents prefer government regulations, parental responsibility, and involvement of independent organizations and firms. External-LOC parents' preference is mediated by their concerns about Internet advertising and their tendency to have faith in regulation. Policy makers can use the findings to develop guidelines that better assist parents in influencing their children's Internet use.

Theoretical comparisons of estimators of finite population proportion under simple random sampling. Stastistics and Applications

Sumanta Adhya, and Tathagata Banerjee

Statistics and Applications

We consider the classical survey problem of estimation of finite population proportions based on a polychotomous response variable when data on an auxiliary variable is known for all units in the finite population. Under simple random sampling different model and design-based estimators are compared theoretically and it is shown that model-based estimator performs more efficiently under mild conditions.

Does the diversification – Firm performance relationship change over time?

Monika Schommer, Ansgar Richter, and Amit Karna

Journal of Management Studies

We study the relationship between diversification and firm performance in the context of the decline in levels of diversification over time. We argue that the pressure to reduce diversification may have more strongly affected those firms whose diversification strategies were most detrimental to firm performance. We employ meta-analytical regression (MARA) in order to test our hypotheses, using a total of 267 primary studies containing 387 effect sizes based on 150,000 firm-level observations from over 60 years of research on the diversification–firm performance relationship. The findings suggest that levels of unrelated diversification have decreased, whereas levels of related diversification have increased since the mid-1990s, following an initial decrease in the 1970s and 1980s. Furthermore, we find that the relationship between unrelated diversification and firm performance has improved significantly over time, whereas the relationship between related diversification and performance has remained relatively stable.

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.

Mining top-k high utility itemsets with effective threshold raising strategies

Srikumar Krishnamoorthy

Expert Systems With Applications

Top-K High Utility Itemset (HUI) mining problem offers greater flexibility to a decision maker in specifying her/his notion of item utility and the desired number of patterns. It obviates the need for a decision maker to determine an appropriate minimum utility threshold value using a trial-and-error process. The top-k HUI mining problem, however, is more challenging and requires use of effective threshold raising strategies. Several threshold raising strategies have been proposed in the literature to improve the overall efficiency of mining top-k HUIs. This paper advances the state-of-the-art and presents a new Top-K HUI method (THUI). A novel Leaf Itemset Utility (LIU) structure and a threshold raising strategy is proposed to significantly improve the efficiency of mining top-k HUIs. A new utility lower bound estimation method is also introduced to quickly raise the minimum utility threshold value. The proposed THUI method is experimentally evaluated on several benchmark datasets and compared against two state-of-the-art methods. Our experimental results reveal that the proposed THUI method offers one to three orders of magnitude runtime performance improvement over other related methods in the literature, especially on large, dense and long average transaction length datasets. In addition, the memory requirements of the proposed method are found to be lower.

Abuse on online labour markets: targets' coping, power and control

Premilla D’Cruz and Ernesto Noronha

European Journal of Operational Research

Purpose

The purpose of this paper is to report a study of targets’ experiences of cyberbullying on online labour markets (OLMs). In addition to highlighting the link between targets’ coping and power and control, the paper compares conventional and digital workplaces.

Design/methodology/approach

The method of critical hermeneutic phenomenology is used in the inquiry, bringing political and applied dimensions into the study. Targets’ lived experiences, developed as case studies, were explored via conversational interviews. Thematic analysis was undertaken ideographically, followed by ideology-critique at a nomothetic level. Adopting the psychological/behavioural lens of coping theory, ideology-critique identified micro-level schemas and macro-level ideologies that perpetuate target disenfranchisement. Critical hermeneutic phenomenology illuminates the mutuality between individual and social processes, opening new doors to address power inequities through emancipation.

Findings

Hermeneutic phenomenology uncovered the core theme of “pursuing holistic and long-term well-being”, capturing targets’ attempts at working through their experiences of bullying without jeopardising their position on the OLM. Ideology-critique went beyond highlighting problem-focussed and emotion-focussed coping strategies that empowered targets to indicate how participants’ mindsets, anchored in ongoing circumstantial discourses and long-standing social cognitions, inhibited them from questioning the status quo and exploring alternative coping strategies like legislation and collectivisation, thereby curbing their agency. The findings were theorised in terms of power and control vis-à-vis the unique attributes of workplace cyberbullying, comparing and contrasting conventional and virtual workplaces.

Research limitations/implications

The inquiry is limited to the Upwork platform. Including other OLMs will enhance theoretical generalisability.

Practical implications

The study feeds into praxis by alerting digital workers in general and targets in particular about their circumstances, setting the stage for mobilisation.

Originality/value

The study makes several pioneering contributions. First, it reports the first empirical inquiry examining bullying in digital workplaces, importantly, also extending knowledge on cyberbullying across conventional versus digital workplaces. Moreover, OLM research on abuse and harassment has not been undertaken so far. Second, methodologically, the inquiry illustrates the combination of hermeneutic phenomenology with ideology-critique, taking the rare steps of joining ontological perspectives conventionally viewed as divergent and of incorporating a largely neglected micro-level focus into ideology-critique. Third, it furthers theoretical insights into power and control in workplace bullying while drawing links with coping.

Target experiences of workplace bullying on online labour markets: Uncovering the nuances of resilience

Premilla D’Cruz and Ernesto Noronha

Employee Relations

Purpose

The purpose of this paper is to report a study of bullying on online labour markets (OLMs), highlighting how abuse unfolds in digital workplaces and depicting the trajectory of target resilience.

Design/methodology/approach

Adopting van Manen’s hermeneutic phenomenology, targets’ lived experiences of bullying on OLMs was explored. Data gathered from Indian freelancers located on Upwork via conversational telephonic interviews were subjected to sententious and selective thematic analyses.

Findings

The core theme of “pursuing long-term and holistic well-being” showed how targets tapped into yet augmented their resilience while navigating the features of OLMs as they coped with their experiences of bullying. The interface between targets’ internal and external resources, including platform support, vis-à-vis the concreteness and permanence of the site as targets asserted agency, sought control and realized positive outcomes while preserving their reputation, relationality, success and continuity was captured. It may be noted that bullying in digital workplaces is exclusively virtual in form.

Research limitations/implications

Alongside theoretical generalizability, statistical generalizability of the findings should be established.

Practical implications

Recommendations for action for platforms and targets are forwarded. In particular, the critical role of formal workplace support in influencing employee resilience is emphasized.

Originality/value

The paper makes several pioneering contributions. First, it reports the first empirical inquiry examining bullying in digital workplaces. Moreover, OLM research on abuse and harassment has not been undertaken so far. Second, it furthers theorization of resilience, especially with regard to workplace antecedents. Apart from identifying the new organizational antecedent of formal workplace support, it uncovers the complexities of resilience. Third, it extends knowledge on workplace cyberbullying, positive outcomes of workplace bullying and OLMs in India.
