The effect of parenthood on travel behavior: Evidence from the California Household Travel Survey

Sandip Chakrabarti and Kenneth Joh

Transportation Research Part A: Policy and Practice

Literature suggests that young children have a significant influence on activity patterns and time-use of adult men and women in dual-earner households. The resultant impact on travel behavior, however, remains largely unexplored. In this study, we use the 2012–13 California Household Travel Survey to compare daily (weekday) travel behavior of adult men and women belonging to dual-earner heterosexual couple households without children, with their adult counterparts in dual-earner heterosexual nuclear households with one or more young (aged 15 years or less) children living in urban California. We find that the presence of young children is, on average, associated with relatively higher auto use, and lower levels of physically active travel (i.e., walking and bicycling) and public transit use. Specifically, parents of school-age (6–15 years) children, without other small (5 years or less) children, are found to engage in significantly more auto use than childless couples. The likelihood of engaging in 20 min or more of active travel per day falls as couples transition to parenthood, and drops further as small children turn school-age. The likelihood of making at least one transit trip per day follows a similar pattern. We also find that the negative impact of young children on average, and school-age children in particular, on adults’ active travel is significantly greater for men than women. Additionally, we identify factors that can help reduce gender inequality in auto use and active travel within households with one or more young children. This study enhances our understanding of travel behavior variations across household types in cities, and over the life courses of individuals. Planning and policy implications are discussed.

Gross profit manipulation through classification

Sakina H. Poonawal and Neerav Nagar

Journal of Business Research

The existing research on classification shifting has examined the manipulation of core earnings through shifting of core expenses to special items keeping the GAAP earnings constant. We examine the manipulation of gross profits through shifting of costs of goods sold to operating expenses keeping core earnings constant. We find that managers, on average, misclassify costs of goods sold as operating expenses in order to just meet prior period's gross margin. We also find that managers shift costs of goods sold to both selling, general and administrative expenses and research and development expenses. However, they are more likely to shift costs of goods sold to the latter.

Food waste due to retail power in suppy chains: Evidence from Sweden

Ranjan Ghosh and Mattias Eriksson

Global Food Security

Trading practices such as the take-back agreement (TBA) can become a tool for retailers to exert coercive power over suppliers when market concentration is high. We explore the implications of TBAs for the Swedish bread industry using unique company data from a premium bread supplier and find that powerful buyers over-order and, thereby, waste. This supplier faced 30% returns on total volume produced in the period 2011–2015 and had to bear the entire cost of bread rejections, collection and disposal. It received payment only for bread sold to end-customers, not the quantity supplied. To our knowledge, this is first time there is substantial evidence of the negative consequences such trading practices lead to with respect to waste. The EU has been considering banning the practices of ‘forcing the supplier to pay for wasted product’ and ‘a buyer returning unsold food products to the supplier’. However, such behaviour is very difficult to prove, given that suppliers-buyers are either tied up with bilateral confidential contracts or operate under relational norms. Yet, TBAs are common in certain food supply chains, presenting a global challenge for prevention of food waste and requiring deeper policy engagement.

Exploring linkages between industrial innovation and public policy: Challenges and opportunities

Rakesh Basant

Vikalpa: The Journal for Decision Makers

It is widely understood now that innovation is critical for development and growth of an economy. World over, governments have worked with a variety of policies to encourage innovative activity. Significant research has gone into the analysis of the complex linkages between public policy and innovation. While this research has generated a lot of interesting insights, it has also identified several gaps in our understanding of these linkages. This article is an attempt to pool together some of the ideas that academic research has highlighted on the linkages between innovation and public policy and identify the current challenges as well as opportunities for meaningfully exploring these linkages further. While it draws a lot on existing studies, the article does not provide a comprehensive or rigorous review of the literature on this subject. It is, at best, a tentative attempt to provide a broad perspective on where we stand vis-à-vis our understanding on the relationship between innovation and public policy. And admittedly, it is one of the many perspectives that a researcher can potentially have on this complex relationship.

Telemedicine for low resource settings: Exploring the generative mechanisms

Rajesh Chandwani and Rahul De

Technological Forecasting and Social Change

Information Communication and Technology for Health (ICT4H) initiatives, such as telemedicine, can potentially bridge the gap between the health care services available in rural and urban areas. However most of such initiatives have not been able to sustain or obtain optimal results. Comprehending knowledge about what drives success in telemedicine initiatives would be highly valuable for practitioners, policymakers and academicians. In this study, through a qualitative analysis of doctor-patient interactions over a telemedicine initiative in India, we attempt to identify the mechanisms that can enable successful telemedicine interventions. Based on the perspective of critical realism, we explore the phenomenon through the lens of ‘generative mechanisms’. Specifically, we identify three different mechanisms that underlie successful telemedicine, namely, (1) Mechanism of rich connectivity, which refers to the expanding scope of information flow between the nodes to include multiple aspects- clinical, managerial and technological; and both online and offline communication; (2) Mechanism of tutoring, which involves learning and skill development of the peripheral doctor; and (3) Mechanism of moulding, which concerns the moulding of naïve patients to expert patients, both in technology use and self management of disease. In addition, the paper demonstrates the efficacy of critical realism as a philosophical perspective for providing substantive insights in the field of ICT4H initiatives.

Stitching infrastructures to facilitate telemedicine for low-resource environments

Rajesh Chandwani and Neha Kumar

Proceedings of the CHI Conference on Human Factors in Computing Systems

Telemedicine can potentially transform healthcare delivery in low-resource environments by enabling extension of medical knowledge to remote locations, thus enhancing the efficiency and effectiveness of the larger healthcare infrastructure. However, empirical studies have shown mixed results at best. We present a qualitative investigation of a long-standing telemedicine program operating from Lucknow (Uttar Pradesh, India). Invoking the lenses of human infrastructure and seamful spaces, we highlight the factors that determine the success of this telemedicine program. We identify and describe three important aspects: (1) conceptualizing telemedicine as the connectedness of two nodes rather than doctors and patients alone, (2) identifying the critical 'carrying agent' (local doctors at peripheral nodes) and engaging them in program design and implementation, and (3) ensuring co-creation by engaging patients in the process. Finally, we discuss how our lenses allowed us to recognize the seams made visible through the juxtaposition of the infrastructures at the central and peripheral nodes, and to emphasize the human elements that addressed these seams for ensuring the facilitation of a successful telemedicine program.

Networks of information exchange: Are link formation decisions strategic?

Pritha Dev

Economic Letters

This paper presents an empirical investigation into whether the decision to form a link with a node takes into account how well connected that node is. Given data in the form of a random sample from a network, this paper proposes a novel way to measure the degree of a node to adjust for mismeasurement and also controls for the endogeneity of this variable. It is shown that in fact the probability of forming a link with a node is increasing in the links received by that node but decreasing or unaffected by the links made by that node.

Group identity in a network formation game with cost sharing

Pritha Dev

Journal of Public Economic Theory

This paper introduces the choice of group identity, which is comprised of characteristics and commitments to these characteristics, in a network formation model where links costs are shared. Players want to link to the largest group given that linking costs for players of the same (different) characteristic are decreasing (increasing) in their commitments. The equilibrium concepts used are Nash equilibrium as well as one that looks for stability allowing for bilateral negotiations. Conditions are shown under which the endogenous choice of characteristics and commitments allow for multiple groups with segregated or connected networks. When group identity is partly endogenous, such that characteristics are fixed and players only choose commitment, it is shown that the equilibrium population commitment profile dictates whether the resulting network is segregated or connected. When group identity is fully endogenous, it is shown that multiple groups and segregated networks are possible equilibrium outcomes but such outcomes are not stable unless the group size additionally affects the costs of link formation.

Power, subjectivity and context in workplace bullying, emotional abuse and harassment: insights from postpositivism

Premilla D’Cruz, Ernesto Noronha, and Pamela Lutgen-Sandvik

Qualitative Research in Organizations and Management: An International Journal

Workplace bullying encompasses subtle and/or obvious negative behaviours embodying aggression, hostility, intimidation and harm. Generally characterized by persistence, these unwelcome acts are displayed by an individual and/or group to another individual and/or group at work, privately and/or publicly, in real and/or virtual forms (D’Cruz, 2015). Alternatively known as workplace emotional abuse or workplace harassment (and referred to as such henceforth), workplace bullying falls under the rubric of dysfunctional and counterproductive workplace behaviours (Fox and Spector, 2005) and is captured by metaphors of nightmares, demons, slaves and heart-brokenness (Tracy et al., 2006) which underscore its unbelievable, demoralizing, humiliating and damaging nature (Lutgen-Sandvik, 2005). It is not surprising, then, that workplace bullying is described as unethical behaviour which goes against universal social rules of acceptability (Ramsay et al., 2011).

Employees' Provident Fund Organization: Empowering members by digital transformation

Ravichandran Narasimhan, Joy P. Vazhayil, and Sundaravalli Narayanaswami

Journal of Public Affairs

Employees' Provident Fund Organization (EPFO) was established by the Government of India with the purpose of ensuring financial and social security for industrial workers and their dependents. With more than 150 million accounts of its members, EPFO is the world's largest social security organization. Operational processes of EPFO were riddled with over emphasis on rules and regulations but were weak on transparency, accountability, effectiveness, and efficiency. Consequently, the primary purpose of social security of industrial employees was compromised. Business process reengineering combined with adoption of Information and Communication Technology (ICT) and social media brought a sea change to the functioning of EPFO. This paper documents the transformation of EPFO from a bureaucratic, opaque organization to a customer-centric, stakeholder-friendly, transparent, and accountable organization.
