Over-ordering and food waste: The use of food delivery apps during a pandemic

Rajat Sharma, Amandeep Dhir, Shalini Talwar, and Puneet Kaur

International Journal of Hospitality Management

There is a paucity of research on the role of food delivery apps (FDAs) in food waste generation. This gap needs to be addressed since FDAs represent a fast-growing segment of the hospitality sector, which is already considered to be a key food waste generator globally. Even more critically, FDAs have become a prominent source of ordering food during the COVID-19 pandemic. In addition, the growing usage of FDAs warrants an improved understanding of the complexities of consumer behavior toward them, particularly during a health crisis. The present study addresses this need by examining the antecedents of FDA users’ food ordering behavior during the pandemic that can lead to food waste. The study theorizes that hygiene consciousness impacts the enablers and barriers to FDA usage, which, in turn, shape the attitude toward FDAs and the tendency to order more food than required, i.e., shopping routine. The conceptual model, based on behavioral reasoning theory, was tested using data collected from 440 users of FDAs during the pandemic. The results support a positive association of trust and price advantage with attitude, but only of trust with shopping routine. Perceived severity and moral norms did not moderate any associations.

Gravity and depth of social media networks

Pritha Guha, Avijit Bansal, Apratim Guha, and Anindya S. Chakrabarti

Journal of Complex Networks

Structures of social media networks provide a composite view of dyadic connectivity across social actors, which reveals the spread of local and global influences of those actors in the network. Although social media network is a construct inferred from online activities, an underlying feature is that the actors also possess physical locational characteristics. Using a unique dataset from Facebook that provides a snapshot of the complete enumeration of county-to-county connectivity in the USA (in April 2016), we exploit these two dimensions viz. online connectivity and geographic distance between the counties, to establish a mapping between the two. We document two major results. First, social connectivity wanes as physical distance increases between county-pairs, signifying gravity-like behaviour found in economic activities like trade and migration. Two, a geometric projection of the network on a lower-dimensional space allows us to quantify depth of the nodes in the network with a well-defined metric. Clustering of this projected network reveals that the counties belonging to the same cluster tend to exhibit geographic proximity, a finding we quantify with regression-based analysis as well. Thus, our analysis of the social media networks demonstrates a unique relationship between physical spatial clustering and node connectivity-based clustering. Our work provides a novel characterization of geometric distance in the study of social network analysis, linking abstract network topology with its statistical properties.

Nurses' perception about Human Resource Management system and prosocial organisational behaviour: Mediating role of job efficacy

Moothedath Luthufi, Jatin Pandey, Biju Varkkey, and Sasmita Palo

Journal of Nursing Management

Aims

To examine the relationship between nurses' perception about human resource management system and prosocial organisational behaviour through job efficacy.

Background

Literature suggests that non-profit organisations are often confronted with financial constraints on one side and the expectation of delivering high-quality services on the other. Employees voluntarily engaging in service-oriented behaviours help to bridge this gap to some extent, and human resource management system plays a significant role in eliciting the requisite behaviours. In this article, the case of nurses from non-profit hospitals has been undertaken to examine the aspects of human resource management system that needs focus while promoting prosocial organisational behaviours among the nurses for ensuring better service delivery.

Method

Cross-sectional design was employed. Data were collected from 387 nurses working in non-profit hospitals in India through questionnaires and were analysed with the help of structural equation modelling.

Findings

In the absence of sophisticated human resource system in non-profit hospitals, the study found that nurses' perception about human resource management system is positively related to prosocial organisational behaviours, and job efficacy partially mediates the relationship.

Conclusion

Positive perceptions such as involvement with the job and communication as well as supervisors' support are essential human resource practices for fostering self-efficacy and, thus, improving prosocial organisational behaviour of nurses working in non-profit hospitals.

Implication for Nursing Management

Non-profit hospitals should focus on nurses' participation and supervisory support, which would provide a better human touch approach to patient care and also improve service quality. The findings shed light on the nursing management of non-profit hospitals in terms of human resource management that has to be given much attention for institutionalizing prosocial organisational behaviour.

New valid inequalities for the symmetric vehicle routing problem with simultaneous pickup and deliveries

Yogesh Kumar Agarwal and Prahalad Venkateshan

Networks

The symmetric vehicle routing problem with simultaneous pickup and deliveries is considered. The current state-of-the-art method to solve this problem employs the idea of a no-good cut. This article achieves an order of magnitude improvement in the computational time needed to solve difficult problem instances by generalizing the no-good cuts and developing a way to generate improved no-good cuts much earlier in a branch-and-bound tree. Results are reported on benchmark instances in literature and new difficult instances generated by the authors. Some polyhedral results are presented about the strength of the generalized no-good cuts for a special case of the problem.

Entry timing as a mixed gamble in cross-border acquisition waves: A study of family firms

Mohammad Fuad, Vinod Thakur, and Ashutosh Kumar Sinha

Family Business Review

We draw upon the mixed gamble perspective to investigate the entry timing decisions made by family firms in the context of cross-border acquisition (CBA) waves. We argue that family-controlled firms trade-off short-term SEW and financial losses in favor of long-term SEW and financial gains, while moving early in CBA waves. Findings suggest that family-controlled firms have a higher preference for early movement compared with nonfamily-controlled firms. Further, we show that founder’s presence on the board and acquirer’s superior performance amplifies the mixed gamble trade-offs, thereby strengthening the relationship between family control and early movement within CBA waves.
