Celebrity endorsements in destination marketing: A three country investigation

Subhadip Roy, Wioleta Dryl, and Luciana de Araujo Gil

Tourism Management

The present study extends research on the role of celebrity endorsements in destination marketing by exploring various facets of the effect of celebrity endorsements in destination marketing on the consumer. More specifically, theories of source credibility, congruence, social identity and consumer cosmopolitanism, are used to build research questions that investigate the relative effectiveness of a celebrity endorsed tourism advertisement vis a vis a generic advertisement and the boundary conditions governing the same such as destination type (local/global), celebrity country of origin and consumer level factors. The research questions are addressed using four experimental studies in sequence. The same four experiments are run in three countries with different socio-cultural backgrounds to enhance generalization, with a combined sample size of 1073 respondents. Major findings suggest that a celebrity endorser is effective for a destination advertisement. Significant cross-country differences were observed in consumer affect depending on the choice of celebrity (local or global) and the destination type (i.e., domestic or international). The effects are also moderated by consumer cosmopolitanism. The study has multiple theoretical and managerial implications.

Farmers’ organizations (FOs), such as associations, cooperatives, self-help and women’s groups, are common in developing countries and provide services that are widely viewed as contributing to income and productivity for small-scale producers. Here, we conducted a scoping review of the literature on FO services and their impacts on small-scale producers in sub-Saharan Africa and India. Most reviewed studies (57%) reported positive FO impacts on farmer income, but much fewer reported positive impacts on crop yield (19%) and production quality (20%). Environmental benefits, such as resilience-building and improved water quality and quantity were documented in 24% of the studies. Our analysis indicates that having access to markets through information, infrastructure, and logistical support at the centre of FO design could help integrate FOs into policy. Natural resource management should also be more widely incorporated in the services provided by FOs to mitigate risks associated with environmental degradation and climate change. Finally, farmers who are already marginalized because of poor education, land access, social status and market accessibility may require additional support systems to improve their capacities, skills and resources before they are able to benefit from FO membership.

The takeoff of open source software: A signaling perspective based on community activities

Pankaj Setia, Barry L. Bayus, and Balaji Rajagopalan

MIS Quarterly

A few open source software (OSS) products exhibit an abrupt and significant increase in downloads. However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship. Posted online August 10, 2020

Unpacking the effects of adverse regulatory events: Evidence from pharmaceutical relabelling

Matthew J. Higgins, Xin Yan, and Chirantan Chatterjee

Research Policy

We provide causal evidence that regulation induced product shocks significantly impact aggregate demand and firm performance in pharmaceutical markets. Event study results suggest an average loss between $569 million and $882 million. Affected products lose, on average, $186 million over their remaining effective patent life. This leaves a loss of between $383 million and $696 million attributable to declines in future innovation. Our findings complement research that shows drugs receiving expedited review are more likely to suffer from regulation induced product shocks. Thus, it appears we may be trading off quicker access to drugs today for less innovation tomorrow. Results remain robust to variation across types of relabeling, market sizes, and levels of competition.

A Note on “The facility location problem with limited distances”

Prahalad Venkateshan

Transportation Science

In this paper, it is shown that the polynomially bounded enumerative procedure to solve the facility location problem with limited distances, originally described by Drezner, Mehrez, and Wesolowsky [Drezner Z, Mehrez A, Wesolowsky GO (1991) The facility location problem with limited distances. Transportation Sci. 25(3):183–187.], and subsequently corrected by Aloise, Hansen, and Liberti [Aloise D, Hansen P, Liberti L (2012) An improved column generation algorithm for minimum sum-of-squares clustering. Math. Programming 131(1–2):195–220.], can still fail to optimally solve the problem. Conditions under which the procedures succeed are identified. A new modified algorithm is presented that solves the facility location problem with limited distances. It is further shown that the proposed correction is complete in that it does not require further corrections.

Different eyes on the same prize: implications of entry timing heterogeneity and incentives for contestant effort in innovation tournament

Swanand J Deodhar

Journal of Business Research

Purpose

This paper examines an apparent contrast in organizing innovation tournaments; seekers offer contestant-agnostic incentives to elicit greater effort from a heterogeneous pool of contestants. Specifically, the study tests whether and how such incentives and the underlying heterogeneity in the contestant pool, assessed in terms of contestants' entry timing, are jointly associated with contestant effort. Thus, the study contributes to the prior literature that has looked at behavioral consequences of entry timing as well as incentives in innovation tournaments.

Design/methodology/approach

For hypothesis testing, the study uses a panel dataset of submission activity of over 60,000 contestants observed in nearly 200 innovation tournaments. The estimation employs multi-way fixed effects, accounting for unobserved heterogeneity across contestants, tournaments and submission week. The findings remain stable across a range of robustness checks.

Findings

The study finds that, on average, late entrant tends to exert less effort than an early entrant (H1). Results further show that the effort gap widens in tournaments that offer higher incentives. In particular, the effort gap between late and early entrants is significantly wider in tournaments that have attracted superior solutions from several contestants (H2), offer gain in status (H3, marginally significant) or offer a higher monetary reward (H4).

Originality/value

The study's findings counter conventional wisdom, which suggests that incentives have a positive effect on contestant behavior, including effort. In contrast, the study indicates that incentives may have divergent implications for contestant behavior, contingent on contestants' entry timing. As the study discusses, these findings have several implications for research and practice of managing innovation tournaments.

It runs in the family: The role of family and extended social networks in developing early science interest

Devasmita Chakraverty, Sarah N Newcomer, Kelly Puzio, and Robert H Tai

Bulletin of Science, Technology & Society

Research shows that early scientific interest is associated with science degree completion and career selection. However, little is known about the conditions that support early scientific interest. Using a “funds of knowledge” theoretical framework, this study examined the role of parents, family, and extended social networks in fostering early interest in science. Using interview narratives from 116 scientists (physicists and chemists) in the United States, we conducted a qualitative thematic content analysis. Findings suggest that children who become scientists in adulthood often received early, informal opportunities to use and manipulate material objects and discover how the world works. Second, families used a wide variety of scientific terms at home and encouraged children to pursue their interests whether in science or other fields. Third, these future scientists were often networked with extended family members or friends to observe and do science when they were quite young. Collectively, these findings highlight the specific ways in which families fostered early scientific interest and aided in supporting a student-directed learning environment.

The Impostor Phenomenon Among Postdoctoral Trainees in STEM: A US-Based Mixed-Methods Study

Devasmita Chakraverty

International Journal of Doctoral Studies

Aim/Purpose

This mixed-methods research study examined impostor phenomenon during postdoctoral training in science, technology, engineering and mathematics (STEM) through the following research question: “What are the manifestations of the impostor phenomenon experienced during postdoctoral training in STEM?”

Background

The impostor phenomenon occurs when competent, high-achieving students and professionals believe that they are fraud and will be exposed eventually. It involves fear of failure, lack of authenticity, feeling fake or fraud-like, denial of one’s competence, and is linked to lower self-esteem, mental health consequences, and lack of belonging.

Methodology

This study was conducted with US-based postdoctoral trainees (or postdocs) using mixed-methods approach. The study examined aspects of impostor phenomenon among 43 postdocs by converging survey data using Clance Impostor Phenomenon Scale (CIPS) and qualitative data from semi-structured interviews from the same participants. Both convenience and snowball sampling were used. Majority of the participants were White, female, and from science disciplines. Interview findings were organized into themes using constant comparative method and analytic induction.

Contribution

Findings pointed to the need for better designing professional development programs for postdocs that would: 1) address fears and insecurities due to impostor-feelings, 2) normalize conversations around perceived failure, judgment, and one’s lack of belonging, and 3) provide support with networking, mentoring, academic communication, and mental health challenges.

Findings

Survey results indicated moderate to intense impostor-feelings; interviews found six triggers of the impostor phenomenon during postdoctoral training: 1. not pursuing new things, 2. not making social connections, 3. impaired academic communication, 4. not applying, 5. procrastination and mental health, and 6. feeling undeserving and unqualified. Current findings were compared with prior findings of impostor-triggers among PhD students who also experienced the first three of these challenges during doctoral training: challenges to applying newly learnt knowledge in other domains, reaching out for help, and developing skills in academic communication verbally and through academic writing.

Recommendations for Practitioners

The office of postdoctoral affairs could design professional development programs and individual development plans for those experiencing the impostor phenomenon, focusing on strengthening skills (e.g., academic writing) in particular. There was an environmental and systemic dimension to the imposter phenomenon, perhaps more prevalent among women in STEM. The academy could devise ways to better support scholars who experience this phenomenon.

Recommendation for Researchers

Research characterizing the qualitative characteristics of the impostor phenomenon across the STEM pipeline (undergrads, PhD students, postdocs, and faculty) would help understand if the reasons and manifestations of this phenomenon vary among differing demographics of students and professionals.

Impact on Society

Organizations could focus on the training, development, mental health, and stressors among postdocs in STEM, particularly by focusing on career transition points (e.g., PhD to postdoc transition, postdoc to faculty transition), especially for those at-risk of experiencing this phenomenon and therefore dropping out.

Future Research

Future research could examine how to manage or overcome the impostor phenomenon for students and professionals, focus on disciplines outside STEM, and investigate how socialization opportunities may be compromised due to this phenomenon. Longitudinal studies might characterize the phenomenon better than those that focused on the impostor phenomenon at a single time-point.

Religious influences in unrestrained consumer behaviour

Jaskaran Singh, Gurbir Singh, Satinder Kumar, and Ajeet N.Mathur

Journal of Retailing and Consumer Services

Religion is known for transforming human behaviour in many ways. This research investigates the influence of religiosity on two unrestrained buying constructs; impulsive and compulsive buying. The focus of this paper is on both intrinsic and extrinsic dimensions of religiosity. The first study provides important insights into the differential impact of these two dimensions of religiosity on unrestrained buying constructs. The second study explores the underlying mechanism of the relationship between extrinsic religiosity and unrestrained buying behaviours. Results show a negative relationship of intrinsic religiosity and a positive relationship of extrinsic relationship with unrestrained buying constructs. We also found that this relationship for extrinsic religiosity is mediated by susceptibility to interpersonal influence and moderated by long-term orientation. This research explains the differential impact of religion on unrestrained buying behaviour.
