Understanding temperature related health risk in context of urban land use changes

Vidhee Avashia, Amit Garg, and Hem Dholakia

Landscape and Urban Planning

A city’s climate is affected both by global warming and the local factors such as built form and the landscape. The temperature related impacts of climate change make urban areas more vulnerable particularly due to higher population concentration as well as heat island effect. Cities in India are already experiencing enhanced temperature and precipitation related impacts of climate change and extreme events, e.g., >2 °C warming in some places. This study describes a case of Ahmedabad – a city of around 5 million people (Census, 2011) and currently almost 7.8 million, located in the hot and humid western part of India to understand the current temperature-related mortality impacts and the role of land use. Satellite images (MODIS from NASA), temperature data from India Meteorological Department (IMD) and daily all-cause mortality from Ahmedabad Municipal Corporation between 2001 and 2015 have been used to create a distributed lag non-linear model. Using land surface temperature for mortality risk assessment gives significantly different results as compared to using air temperature for mortality risk assessment. This indicates impacts of localized temperature variations on mortality risks. Thus, the microclimate in a city as represented by land surface temperatures is a better indicator for estimating relative risk of temperature related mortality as compared to air temperature. The study also infers that with increase in built-up spaces by 1% in the land use mix, the relative risk of heat related mortality increases by 0.59 points at 40 °C and by 0.78 points at 45 °C.

Quantifying the local cooling effects of urban green spaces: Evidence from Bengaluru, India

Arpit Shah, Amit Garg, and Vimal Mishra

Landscape and Urban Planning

Rapid unplanned urbanization has led to a deterioration in green cover in Indian cities and an increase in urban temperatures due to the urban heat island (UHI) effect. With India’s urban population set to double from 400 million in 2011 to 800 million by 2050, it becomes critical to understand the role of urban green spaces (UGS) in mitigating the UHI. In this study, we have used high-resolution Landsat and Google Earth data and integrated it with spatial statistical analysis to quantify the cooling effects provided by UGS beyond their boundaries. We analyzed cooling effects at the level of individual UGS for 262 UGS in the megacity of Bengaluru, India. Our results showed that the average UGS provided local cooling effects till points 347 m (95% CI: 318 m to 376 m) beyond its boundary. The average UGS was 2.23 °C (95% CI: 2.13 °C to 2.33 °C) cooler than the point where it ceased to provide cooling effects. Cooling effects reduced with distance from the UGS, and were impacted by the greenness, size, and shape of the UGS. The findings of this study are important in the context of India’s Smart Cities Mission that has been criticized for an inadequate focus on urban greening. Our study addresses a concern that most previous studies have used a small sample of UGS for their analysis. To the best of our knowledge, this is the first study to quantify the role of UGS in localized surface temperature reduction for a large Indian city.

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.

Rational repricing of risk during COVID-19: Evidence from Indian single stock options market

Sobhesh Kumar Agarwalla, Jayanth R. Varma, and Vineet Virmani

Journal of Futures Markets

Could the COVID-19 related market crash and subsequent rebound be explained as a rational response to evolving conditions? Our results using multiple forward-looking measures of uncertainty implied from stock option prices suggest so. First, we find a gradual build-up of volatility during the month preceding the spike at the start of the pandemic. Second, while tail risk declined after government interventions, the level of uncertainty remained elevated for stocks across industries. Third, the dynamics of decline in tail risk in stocks was industry-dependent, suggesting that the market performed a fine-grained analysis of each stock's uncertainty through the pandemic.

Family firms and their participation in cross-border acquisition waves: evidence from India

Mohammad Fuad, Vinod Thakur, and Ashutosh Kumar Sinha

Cross Cultural & Strategic Management

Purpose – From the socioemotional wealth (SEW) perspective, family firms prioritize non-financial goals and show risk averse behaviour towards conducting acquisitions. In this paper, we study family firms' acquisitive behaviour while participating in CBA waves. Scholars have largely treated the cross border acquisition (CBA) wave and non-wave environments as homogeneous. We theorize that these two environments differ in their uncertainty and risk profiles on account of temporal clustering of acquisition deals. Accordingly, based on the SEW perspective, we examine the preference of family firms to participate in CBA waves. Design/methodology/approach – The paper is based on CBAs conducted by Indian family firms between 2000 and 2018. These waves are identified by conducting a simulation based methodology. Findings – Our findings suggest that foreign institutional ownership, firm age and acquisition relatedness moderate the relationship between family control and participation in CBA waves. Originality/value – Our paper contributes towards the acquisitive behavior of family firms and their participation in CBA waves.

Impostor phenomenon among engineering education researchers: An exploratory study.

Devasmita Chakraverty

International Journal of Doctoral Studies

Aim/Purpose

The purpose of this study was to explore reasons that engineering education researchers experience impostor phenomenon.

Background

Experiencing impostor phenomenon includes a psychological discomfort experienced by some high-achieving individuals who, by the very virtue of being successful, mistakenly believe that they are fraudulent and faking their success. Impostor phenomenon has been studied more broadly in science, technology, engineering, and mathematics (STEM), with little research specifically in engineering and computer science and none, to the author’s knowledge, in engineering education research. As an emerging discipline, some of the challenges in engineering education research include its poor connection with engineering teaching and learning, establishing multidisciplinary collaborations, and advancing global capacity. As a result of its poor connection with engineering fields, and being a new discipline, it is possible that engineering education researchers hold an identity that is different from engineering researchers. Some of them could be experiencing their training differently, struggling to find mentors from a similar background, and possibly feeling like impostors.

Methodology

Using purposive sampling and snowball sampling, US-based engineering education researchers participated in a short survey and a semi-structured interview. The survey consisted of demographic questions, items of the Clance Impostor Phenomenon Scale, and an open-ended question about an instance when participants experienced impostor phenomenon. Interviews examined, in detail, reasons for experiencing impostor phenomenon as engineering education researchers. The scale provided a measure of the intensity of impostor phenomenon. Interviews were analyzed inductively through constant comparison using a constructivist approach.

Contribution

Findings indicated various axes of othering (separating those who are perceived as different, non-dominant, or outsiders from the majority or popularly accepted norm) that made it difficult to develop a sense of belonging, especially for women, and contributed to impostor phenomenon. Othering occurred through identity-based experiences (gender-identity, engineer-identity), different methodologies used to conduct research, and different vocabulary used for academic communication.

Findings

The sample comprised of eleven participants (PhD students, postdoctoral scholars, and faculty), all of whom experienced high to intense impostor phenomenon (range: 61-91/100; mean 75.18). Participants were predominantly white women from twenties to forties. Interviews indicated two reasons for experiencing impostor phenomenon: (1) existing in a separate world from engineering (referring to cultural differences between engineering and engineering education including differences in communication styles, methodologies, and identities); and, (2) facing gendered experiences (for women).

Recommendations for Practitioners

It is recommended that practitioners are mindful of the tensions between worldviews, commonly used methodologies, and demographic differences between engineering research and engineering education research that could shape one’s experience in the field and contribute to “othering” during doctoral training and thereafter.

Recommendation for Researchers

Doctoral and post-doctoral training in engineering education research could be more inclusive and open to different research methodologies. Future studies deeply exploring various training challenges experienced by engineering education researchers could illuminate how the field could become more inclusive.

Impact on Society

The current study provides a nuanced understanding of the dichotomy between engineering and engineering education research, including the different styles in academic communication, research methodologies used, and identities. It also provides an understanding of the gendered experiences women have in the field, pointing to an overt or covert lack of recognition. Both these factors could make some feel like outsiders or impostors who question themselves and doubt their competencies and belonging in the field. Attrition from the field could be costly, even to the society, at large, given that the field is relatively new, evolving, and not (yet) as diverse in its worldviews, methodologies, and the demography of those it attracts for doctoral training and beyond. The study provides evidence-based understanding of how training in engineering education researchers could be re-imagined.

Future Research

Future research could examine, in detail, aspects of engineering education research training that may contribute to impostor phenomenon, poor belonging, poor identity, and othering experiences.

Lottery and bubble stocks and the cross-section of option-implied tail risks

Sobhesh Kumar Agarwalla, Sumit Saurav, and Jayanth R. Varma

Journal of Futures Market

The options smile provides forward-looking information about the risk at the center of the distribution (ATM-IV) and at the tails (Skew). We investigate the cross-sectional determinants of the options smile using indices that capture firm fundamental risks, heterogeneity in belief, lottery characteristics, and bubble characteristics. We find that at-the-money (ATM) volatility is explained mainly by historical risks and predicted future risks measured using accounting-based risk measures and firm characteristics. However, the cross-sectional variation in the skew is driven by risk premia and by buying and selling pressure, which is influenced by heterogeneity in belief and the underlying's lottery-like and bubble-like characteristics.

Time discount rate of forest-dependent communities: Evidence from Andhra Pradesh

Sundar Balakrishna and Vineet Virmani

Vikalpa: The Journal for Decision Makers

This study presents evidence on time discount rate of forest-dependent communities (FDCs) in the backdrop of the joint forest management program launched by the Government of India in 1990. The study uses data from two regions of the Indian state of Andhra Pradesh—Rayalaseema (a relatively dry forest region with low income) and the coastal region (relatively fertile forest and with higher income). We also identify socio-economic determinants of their patience levels and factors which distinguish the two regions. To elicit individual discount rates of FDCs members and their determinants, we use the choice task design methodology. Members from both regions were found to be highly impatient using the standard choice task design with the revealed time discount rate averaging 800% per annum. Members of FDCs from Rayalaseema were more impatient than their counterparts from the coastal region, although the statistical evidence is weak. We find no association between the income of members of FDCs and their time discount rate for both regions. Membership to caste categories showed a different response in both the regions, with members from the Scheduled Caste category and Other Backward Classes found to have a lower discount rate than those from the Scheduled Tribes category of Rayalaseema region and vice versa for the coastal region. For the coastal region, those with larger family size and heads of households were found to have a lower discount rate.
