The Impact

In this study, we examined the results and interpretations produced from two different IRTree models—one using paths consisting of only dichotomous decisions, and one using paths consisting of both dichotomous and polytomous decisions. We used data from two versions of an impulsivity measure. In the first version, all the response options had labels; in the second version, only the endpoints were labeled. Based on past research, we hypothesized that the endpoints would be selected more frequently in the endpoint-only labeled condition, and the midpoint response option would be selected more frequently in the fully labeled condition. Results from the two models (dichotomous and polytomous) were similar and indicated that our hypotheses were partially supported—specifically, there was no consistent pattern in terms of which condition saw a higher frequency of midpoint response selection. However, our hypotheses regarding extreme responding in the endpoint-only labeling condition were supported.

Abstract Research into the impact of a politician's sociodemographic profile on vote choice in Westminster-style systems has been hindered by the relative sociodemographic homogeneity of party leaders. Past research has focused mainly on the evaluation of local candidates in the American context, but given that elections in plurality systems are far less candidate-oriented , the evaluation of local candidates tells us little about the prevalence of affinity or discrimination in other contexts. This article investigates the effect of political leaders' ethnicity on political behavior by looking at the case of Jagmeet Singh in Canada, the first federal party leader of color in the country's history. While the literature has shown that the gender of leaders in Canada can matter, little is known about the attitudes of Canadians toward party leaders of color specifically. We are interested in the evaluations of Singh and his party, as well as the shifts in voting intentions between elections in 2015 and 2019. We uncover affinity-based behaviors from individuals who identify as Sikh, as well as a negative reception of Singh's candidacy in Quebec.

The Impact

Past research has found that a perceived meaning in life can act as a protective factor against adverse mental health symptomology, while also providing coping resources to buffer against the impact of negative life events. The current research investigated how the impact of self-perceived meaning in life as well as its predictors interact with stressors and worry related to the COVID-19 pandemic. We collected survey based data (n = 260) from Australian participants during the pandemic, measuring their meaning in life, orientation to differing life goals and COVID-19 related stressors via the impact of events scale. We found that meaning in life predicted less stress and worry associated with COVID-19. We also found that intrinsic based aspirations related positively to meaning in life within this context whereas extrinsic based goals related negatively to it, although these aspirations were not significant in reducing the stressors associated with COVID-19. These results reinforce past findings that meaning in life can effectively buffer against the impact of negative life events such as the COVID-19 pandemic. They also suggest that intrinsic based aspirations centred on relationships and self-acceptance may be an important mechanism in how people choose to pursue life meaning during uncertain life events.

Abstract Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of pulmonary hypertension caused by blood clots and scar tissue in the blood vessels of the lungs. Health-related quality of life is often significantly impaired in patients with CTEPH. However, a better understanding of how CTEPH symptoms affect patients’ lives is needed to optimally assess the impact of the disease and treatment. Objectives This qualitative study aimed to better understand the symptoms of CTEPH and how they affect patients’ lives, as well as to determine the appropriateness of the Pulmonary Arterial Hypertension – Symptoms and Impact (PAH-SYMPACT™) questionnaire for use in this patient population. Methods Adults diagnosed with CTEPH, recruited from two clinical sites in the US, participated in one-to-one qualitative telephone interviews. They described their experience of CTEPH symptoms and the impact these symptoms have on their lives. They also provided feedback on the comprehensibility and relevance of the PAH-SYMPACT™‘s instructions, items, and response options. Results Participants (N = 12) had a mean age of 62.5 years. Two thirds were female and most (83%) had undergone pulmonary endarterectomy and/or balloon pulmonary angioplasty. The most frequently endorsed symptoms were shortness of breath (endorsed by all 12 participants), fatigue (11 participants), and lightheadedness (10 participants). All participants identified shortness of breath as an “extremely important” symptom, and seven participants rated fatigue as “extremely important.” The most frequent impacts of CTEPH were on ability to walk quickly (endorsed by all 12 participants), ability to walk up inclines or stairs (11 participants), and ability to carry things (11 participants). The PAH-SYMPACT™ items were relevant to most participants and reflected their experience of CTEPH. All participants indicated that no important CTEPH symptoms were missing from the PAH-SYMPACT™. Overall, the instructions, items, and response options of the PAH-SYMPACT™ were clear and easy to understand. Conclusions The symptoms and impacts experienced by patients with CTEPH align with items included in the PAH-SYMPACT™. The PAH-SYMPACT™ appears to be fit for purpose for assessing disease status in patients with CTEPH.

AbstractUnemployment shocks from the COVID-19 pandemic have reignited concerns over the long-term effects of job loss on population health. Past research has highlighted the corrosive effects of unemployment on health and health behaviors. This study examines whether the effects of job loss on changes in body mass index (BMI) are moderated by genetic predisposition using data from the U.S. Health and Retirement Study (HRS). To improve detection of gene-by-environment (G × E) interplay, we interacted layoffs from business closures—a plausibly exogenous environmental exposure—with whole-genome polygenic scores (PGSs) that capture genetic contributions to both the population mean (mPGS) and variance (vPGS) of BMI. Results show evidence of genetic moderation using a vPGS (as opposed to an mPGS) and indicate genome-wide summary measures of phenotypic plasticity may further our understanding of how environmental stimuli modify the distribution of complex traits in a population.

Operator Workload

The use of alarms has increased in many operational areas because of increased reliance on automation and the duty to warn about system anomalies. Past research has supported the use of verbal alarms for relaying complex information. However, researchers have not considered the impact of vocal alarms on operator trust. In this research, 56 participants reacted to auditory alarms while performing a complex primary task. Half of the participants experienced vocal alarms, and the others experienced nonvocal alarms. Contrary to expectations, we noted that participants reacted to nonverbal alarms more quickly than verbal alarms. Furthermore, participants responded to verbal alarms more often than verbal alarms. We also noted that verbal alarms interfered with the primary task more than nonverbal alarms. We suggest that alarm designers alter verbal alarm onset algorithms during high operator workload.

The Impact

Past research has indicated that Major Depressive Disorder and exposure to violence are risk factors for offending. However, researchers have yet to examine how this disorder may predict recidivism risk among juvenile offenders and how the disorder moderates the effect of exposure to violence. Kaplan-Meier survival analysis was used to determine the impact of Major Depressive Disorder on time to recidivism. Cox proportional hazard modeling was applied to examine Major Depressive Disorder as a moderator of exposure to violence. Results indicated that participants with Major Depressive Disorder demonstrate greater risk for recidivism post-adjudication. The proposed moderation effect was not supported.

Corporate Mobility

Orientation: Corporate mobility remains elusive for female managers.Research purpose: To investigate Batswana female managers’ strategies for entering and succeeding in managerial positions, the challenges they face and the consequences of success.Motivation for the study: There is a lack of research into the way Batswana female managers obtain management positions, as well as their experiences as female managers.Research approach, design and method: An interpretive approach using a case study strategy was employed. Semi-structured interviews were conducted which were shaped by the objectives of the study. A sample of female employees (n = 10), representing different organisations and professions, was obtained from various organisations in Botswana.Main findings: Findings revealed that female managers do experience a number of challenges. Various factors were identified that accounted for their career advancement as well as the consequences of success. The consequences of success were identified as being both positive and negative.Practical/managerial implications: The current study is important as the strategies for success that were identified can be used to assist interested women to obtain management-level positions. Furthermore, the challenges identified may assist both researchers and practitioners to design interventions that help to mitigate the challenges, in turn enabling the inclusion and advancement of women in leadership or managerial positions.Contributions: The current study may contribute new knowledge as past research conducted in Botswana seems to have focused mainly on the impact of regulatory and legislative challenges on women’s advancement. Such a focus ignores the other aspects of female managers’ experiences, which are addressed by the current study.

Victimization is associated with traumatic harm, bringing inherent importance to efforts to understand why victimization occurs. Past research has shown that economic and demographic factors affect the probability that individuals will experience bribery, crime, and discrimination. We build on this foundation by arguing that a fuller account of victimization must include the impact of differences in personality. To test our hypotheses, we utilize survey data from 22 nations in the Americas. Results show that openness and extraversion increase the probability of victimization and agreeableness decreases it.
