Medical Education Online

Many U.S. medical schools conduct holistic review of applicants to enhance the socioeconomic and experiential diversity of the physician workforce. The authors examined the role of first-generation college-graduate status on U.S. medical school application, acceptance, and matriculation, hypothesizing that first-generation (vs. continuing-generation) college graduates would be less likely to apply and gain acceptance to medical school.Secondary analysis of de-identified data from a retrospective national-cohort study was conducted for individuals who completed the 2001–2006 Association of American Medical Colleges (AAMC) Pre-Medical College Admission Test Questionnaire (PMQ) and the Medical College Admissions Test (MCAT). AAMC provided medical school application, acceptance, and matriculation data through 06/09/2013. Multivariable logistic regression models identified demographic, academic, and experiential variables independently associated with each outcome and differences between first-generation and continuing-generation students. Of 262,813 PMQ respondents, 211,216 (80.4%) MCAT examinees had complete data for analysis and 24.8% self-identified as first-generation college graduates. Of these, 142,847 (67.6%) applied to U.S. MD-degree-granting medical schools, of whom 86,486 (60.5%) were accepted, including 14,708 (17.0%) first-generation graduates; 84,844 (98.1%) acceptees matriculated. Adjusting for all variables, first-generation (vs. continuing-generation) college graduates were less likely to apply (odds ratio [aOR] 0.84; 95% confidence interval [CI], 0.82–0.86) and be accepted (aOR 0.86; 95% CI, 0.83–0.88) to medical school; accepted first-generation college graduates were as likely as their continuing-generation peers to matriculate. Students with (vs. without) paid work experience outside hospitals/labs/clinics were less likely to apply, be accepted, and matriculate into medical school. Increased efforts to mitigate structural socioeconomic vulnerabilities that may prevent first-generation college students from applying to medical school are needed. Expanded use of holistic review admissions practices may help decision makers value the strengths first-generation college graduates and other underrepresented applicants bring to medical educationand the physician workforce.

Prospect theory preferences and global mutual fund flows

Nilesh Gupta, Anil V. Mishra, and Joshy Jacob

Journal of International Money and Finance

We examine the influence of Cumulative Prospect Theory (CPT) characteristics of fund returns on investment flows with a cross-country data of equity mutual funds. We find that a larger CPT value of the style-adjusted past returns is associated with higher fund flows in the subsequent quarter. The impact is greater for retail-oriented funds, relatively younger funds, and those with higher active share. While funds that score high on the CPT value attract incremental fund flows, they earn a lower alpha than their peers in the following year. The sensitivity of fund flows to the CPT characteristics is higher in countries with greater individualism and short-term orientation. The results are robust to several additional tests and hold across various subsamples of our data. The findings imply that investors have misplaced expectations about the future performance of funds that show higher CPT values and the fund managers cater to these investor preferences.

A bilevel conic optimization model for routing and charging of EV fleets serving long distance delivery networks

Vignesh Subramanian, Felipe Feijoo Sriram Sankaranarayanan, Kevin Melendez, and Tapas K. Das

Energy

Recent unveiling of electric semi-trucks by a number of electric vehicle manufacturers indicates that part of the existing long-distance transportation fleets may soon be electrified. Operators of electric fleets will have to select travel routes considering charging station availability and cost of charging in addition to usual factors such as congestion and travel time. This requires combined modeling of transportation and electric power networks. We present such a model that considers interactions between the two networks to develop optimal routing strategies. The problem is formulated as a multi-objective bilevel conic optimization model. The upper level obtains the routing decision by minimizing a function of charging cost and travel time. The routing decision is used in the lower level that solves the AC optimal power flow model, using second order cone constraints, to determine nodal electricity prices. The model is demonstrated using a numerical problem with 24-Node transport network supported by a modified 5-Bus PJM network. The results show that our model yields optimal routes and charging strategies to meet the objectives of fleet operators. Results also indicate that the optimal routing and charging strategies of the electrified transportation fleet can support power networks to reduce nodal prices via demand response.

Work life balance indicators and Talent Management approach: A qualitative investigation of Indian luxury hotels

Sunil Buddhiraja, Biju Varkkey, and Stephen McKenna

Employee Relations: The International Journal

Purpose – The purpose of the study is twofold: (1) it captures the work–life balance (WLB) experiences of front-office employees to inductively classify a set of WLB indicators for the locally owned Indian luxury hotels and (2) it further examines the existing WLB practices of the select hotels with the lens of talent management (TM) approach of key human resource management (HRM) practices (Thunnissen, 2016). Design/methodology/approach – To explore and classify WLB indicators, an exploratory, qualitative approach is utilized by administering seven focus group discussions involving 70 front-office employees working in Indian luxury hotels. Seven in-depth interviews with HR professionals were triangulated with secondary data to capture and analyse the existing WLB practices of sampled organizations. Findings – Four clusters of WLB indicators that are grounded in the lived experiences of front-office employees are identified and presented. Interview data from human resource representatives unveil that hotels consider existing WLB practices as key HRM practices with an inclusive TM approach. The findings also surface the differences in expectations of front-office employees and WLB practices followed by the hotels. Research limitations/implications – First, the paper addresses the issue of WLB from employees’ perspective which is crucial for designing effective WLB practices. Second, the paper contributes to the existing TM literature from the perspective of WLB practices. Originality/value – The originality of the study is grounded in the employees’ lived experiences to classify the WLB indicators for India and further examine the WLB practices through the lens of the TM approach.

How COVID-19 lockdown has impacted the sanitary pads distribution among adolescent girls and women in India

Karan Babbar, Niharika Rustagi, and Pritha Dev

Journal of Social Issues

This paper empirically explores the impact of COVID-19 pandemic and its accompanying lockdown on adolescent girls’ and women's access to sanitary pads in India. We have used the National Health Mission's Health Management Information System (NHM-HMIS) data for the study, which provides data on pads' distribution on a district level. The empirical strategy used in the study exploits the variation of districts into red, orange, and green zones as announced by the Indian Government. To understand how lockdown severity impacts access to sanitary pads, we used a difference-in-difference (DID) empirical strategy to study sanitary pads' access in red and orange zones compared to green zones. We find clear evidence of the impact of lockdown intensity on the provision of sanitary pads, with districts with the strictest lockdown restrictions suffering the most. Our study highlights how sanitary pads distribution was overlooked during the pandemic, leaving girls and women vulnerable to managing their menstrual needs. Thus, there is a requirement for strong policy to focus on the need to keep sanitary pads as part of the essential goods to ensure the needs of the girls and women are met even in the midst of a pandemic, central to an inclusive response.

Informal land leasing in rural India persists because it is credible

Yugank Goyal, Pranab Ranjan Choudhury, and Ranjan Kumar Ghosh

Land Use Policy

While insecure property rights are considered ‘perverse’ with respect to development, we examine what are the features most amenable for their persistence. Applying a Credibility Thesis framework in the context of rural land tenancy relations in India, that are largely held through private arrangements, we try to understand if there are inherent preferences to the existing informal structure of land leasing. An in-depth primary household survey across four states of India reveals that farmers rely on customary, informal mode of leasing arrangements because of their functionality in terms of no paperwork, easy accessibility, swifter modes of payment and prompt conflict resolution. Informality makes the existing institutional arrangement ‘credible’ in the eyes of both the tenants and owners. This raises the questions of whether policy prescriptions on intricate land related issues should entail appreciation of prevailing informal tenant customs, regulating them, or simply letting them be and realign agrarian support and delivery systems around this embedded informality.

A two-stage integer programming model considering transaction equivalence for privacy preservation

Srikumar Krishnamoorthy

Computers and Operations Research

Preserving privacy is one of the fundamental requirements of firms that share data with their business partners for building advanced data mining models. Firms often aim to protect the disclosure of sensitive knowledge or information discovered during the data mining process. In this study, we investigate the problem of Frequent Itemset Hiding (FIH) which aims to hide sensitive itemset relationships present in a transactional database. We propose a two-stage integer programming model that maximizes the proportion of unaltered transactions in the sanitized database and protects sensitive itemset relationships. The model exploits the concept of transactional equivalence and significantly reduces the size of the FIH problem. In addition, our model enables the identification of solutions with minimal side effects. We conduct an experimental evaluation on both real and synthetic databases to show that our approach is scalable and produces a sanitized database with maximum accuracy. The generated solution is also found to have lower side effects (itemset information loss) compared to other state-of-the-art methods. Our experiments on very large problem instances show problem size reductions of one to three orders of magnitude. The proposed approach is quite attractive and practically useful for solving large-scale FIH problem instances and preserving privacy in increasingly shared and big data-driven organizational environments.

Impostor phenomenon and identity-based microaggression among hispanic/Latinx Individuals in Science, Technology, Engineering, and Mathematics: A Qualitative Exploration

Devasmita Chakraverty

Violence and Gender

Impostor phenomenon is defined as a psychological condition when some successful people do not fully ascribe their success to ability or competence, but attribute it to luck, generosity from others, or misjudgment, thereby experiencing an internal conflict. Microaggression is defined as subtle disparaging behavior that consciously or unconsciously discriminates people based on their background, personal identity, and group membership. Both impostor phenomenon and microaggression are commonly experienced in science, technology, engineering, and mathematics (STEM) fields, especially by women and BIPOC individuals—black, indigenous, or other person of color. Hence, the connection between microaggression and impostor phenomenon among BIPOC individuals needs deeper exploration. This qualitative study examined the research question: How do Hispanic/Latinx PhD students and postdoctorates in STEM describe impostor phenomenon and microaggression based on ethnic identity? U.S.-based participants were recruited using convenience sampling and snowball sampling. Semistructured interviews were conducted with 29 participants who self-reported experiencing impostor phenomenon. Interview transcripts were coded and analyzed inductively using constant comparison to develop themes. Twenty-two of the participants (18 women) experienced microaggression during training based on their Hispanic/Latinx identity. Microaggressive comments were made by faculty members, peers, and others in academia. Microaggression and impostor phenomenon were related through “othering” or feeling like outsiders, creating a sense of (un)belonging in STEM fields.

Disentangling reciprocal relationships between R&D intensity, profitability and capital market performance: A panel VAR analysis

Amit Karna, Christos Mavis, and Ansgar Richter

Long Range Planning

Research and development (R&D) investments are strategic choices that firms make to create and sustain competitive advantage. Extant literature proposes that firms’ R&D investments and their profitability and capital market performance are reciprocally related. However, the direction of these relationships and their temporal nature are unclear. We take a real options perspective to argue that the long-run firm performance effects of R&D investments are better than their short-term ones, and that the initial level of R&D intensity influences the nature of these relationships. We apply panel vector autoregression (P-VAR) to a sample of 6623 U.S. firms over the 1990–2020 period in order to test our hypotheses. Our results indicate that increases in R&D intensity have negative effects on profitability in the short term, yet these effects diminish relatively quickly. The effects of increases in R&D intensity on capital market performance are positive and persist over time. Consistent with our predictions, they are contingent on the initial levels of R&D intensity and performance. The findings are fundamentally in line with the real options perspective employed here, yet they add important nuance to our understanding of when, how, and under which conditions R&D investments and firm performance affect one another.

Big-4 auditors and audit quality: A novel firm life-cycle approach

Sonali Jain and Sobhesh Kumar Agarwalla

Meditari Accountancy Research

Purpose – Firm-specific factors such as size, profitability, growth, risk and complexity, in addition to agency-related issues determine both auditor selection and firm life-cycle stage. This paper aims to examine whether and how the effect of Big-4 auditors (B4As) on client firms’ audit quality varies across firms’ life-cycle stages. Design/methodology/approach – The sample comprises 1,813 firm-year observations in India’s emerging economy from 2011 to 2020. The Modified Jones model and Jones (signed, unsigned) model are used to compute discretionary accruals/audit quality. The authors use Koh et al.’s (2015) methodology to determine the firm life cycle. Findings – The authors’ key findings show that the client firms employing B4As have superior audit quality than those employing non-Big-4 auditors (NB4As). The authors also show that the life-cycle stage significantly impacts the relationship between B4As and a firm’s audit quality. Furthermore, B4A client firms report superior audit quality vis-à-vis NB4A firms only in the birth- and decline-stages. The audit quality of growth- and mature-stage B4A and NB4A client firms is not significantly different. Practical implications – Implications for managers include the decision to hire B4As. Given that B4As earn a significant fee premium, managers leading birth- and decline-stage firms should hire B4As, while managers of growth- and mature-stage firms should not. Originality/value – To the best of the authors’ knowledge, this is the first paper to examine the moderating effect of the firm life-cycle stage on the selection of B4As and their impact on audit quality.
