The Role of Dopamine Receptor D2 in Bridging the Intention-Behavior Gap in Sport Participation

Previous studies have identified that a behavior can occur through the strongest predictor intention, but there is a gap between intention and behavior. Dopamine receptor D2 (DRD2) is known to account for a variance in sporting behaviors in human and animal subjects. However, the relationship between DRD2 and sport participation has been poorly studied, and the limited available reports are inconsistent. The present study was performed to examine the impact of DRD2 on sport participation among Korean university students based on the integrated behavioral model (IBM). Data were collected from enrolled university students in Seoul (N = 45). Participants answered survey questions first, and then they gave investigators their hair to provide DNA information (i.e., the A1 allele of DRD2). DRD2 had a significant effect on sport participation, but only in male students. Male students who carried the A1 allele of DRD2 significantly participated in 105.10 min more sporting activities than male students who did not. Moreover, the effect of intention on sport participation was significantly decreased when considering DRD2. Despite the small sample size, the results of this study could be a preliminary case for a larger study and indicate the direction of future research. Our results suggest that DRD2 may have played an important role as the “actual skill” shown in the IBM.

Review Session

Introduction: The National Board of Medical Examiners (NBME) subject examinations are used as a standardized metric for performance in required clerkships for third-year medical students. While several medical schools have implemented a review session to help consolidate knowledge acquired during the clerkship, the effects of such an intervention are not yet well-established. An improvement in NBME psychiatry examination scores has previously been reported with a single end-of-clerkship review session, but this was limited by a small sample size and the fact that attendance at the review session was optional, leading to likely selection bias.Methods: A 1.5-hour structured review session was conducted for medical students in the last week of each 4-week psychiatry clerkship between September 2014 and July 2015. Students were required to attend unless excused due to scheduling conflicts. Scores on the NBME psychiatry subject exam were compared with those of students taking the examination in the corresponding time period in each of the previous two academic years.Results: 83 students took the exam during the experimental period, while 176 took the exam during the control period. Statistically significant improvements were found in mean score (p=0.03), mean for the two lowest scores in each group (p<0.0007), and percentage of students scoring 70 or less (p=0.03). Percentage of students achieving the maximum possible score (99) was higher in the experimental group, but did not reach significance (p=0.06).Conclusions: An end-of-clerkship review session led to increased mean scores on the NBME psychiatry subject examination, particularly for students at the lower end of the score range. Future research should investigate the impact of such an intervention in other specialties and other institutions.

The Impact

Clinical experience indicates that excessive sleepiness and hypersomnia may be a common issue for patients with psychosis. Excessive sleepiness is typically ascribed to the sedating effects of antipsychotic medications but there may be other potential contributors such as sleep disorders and depression. Furthermore, the impact of excessive sleepiness itself on patients’ symptoms and general wellbeing is yet to be examined. The current study reports an exploratory cross-sectional between-groups comparison of patients with early psychosis fulfilling criteria assessed in a diagnostic interview for problematic excessive sleepiness (n = 14), compared with those not reporting excessive sleepiness (n = 46). There were no differences between the groups in diagnosis, medication type, or antipsychotic medication dosage. There were no significant group differences in sleep duration. Significantly lower activity levels were found in the excessive sleepiness group. Insomnia and nightmares were common in those reporting excessive sleepiness. No significant differences were found in psychiatric symptoms, although data did indicate more severe cognitive disorganisation and grandiosity, but less severe paranoia and hallucinations, in the excessive sleepiness group. Wide confidence intervals and small sample size mean that care should be taken interpreting these results. Overall, this study indicates that excessive sleepiness may not be solely related to medication but also to low levels of activity and other sleep disorders. This is a novel finding that, if replicated, could indicate routes of intervention for this clinical issue. Future research should aim to disentangle directions of effect amongst sleepiness, mood, activity, and psychotic symptoms and investigate possible interventions for excessive sleepiness in psychosis.

Christian Denomination

Purpose This paper aims to explore the experiences of church ministers who played the role of transitional leaders in congregational situations involving conflict. Design/methodology/approach Grounded theory was chosen as a suitable approach to investigate phenomena that occasionally penetrate religious publications and even less frequently scholarly management journals. Accordingly, in-depth interviews were conducted with six church ministers who had been transitional leaders in one Christian denomination in New Zealand. Findings Participants indicated that the drivers of transitional ministry were conflict, dysfunction and loss of direction; the goals were to heal the damage caused by conflict and restore functionality and well-being; the process, underpinned by a leadership philosophy of affirmation, trust-building, engagement and communication, involved working with church members to instil hope, establish operational structures, identify and resolve dysfunction, envision a future and ultimately recruit a permanent minister. Research limitations/implications The limitations of a small sample size in one Christian denomination could be addressed by using wider samples in other contexts. It is suggested that insights into transitional leadership after conflict will be of interest to researchers as well as practitioners in other religious organizations, the wider non-profit sector and the private sector. Future research into the impact of transitional leadership, against a background of conflict and organizational change, will add to this empirical foundation. Originality/value The model of transitional ministry is a unique contribution to religious literature and practice. It also offers insight into how other types of organization could deal with the exit of its permanent leader, in circumstances of conflict, and manage the transition phase of a temporary replacement, so that the organization returns to a state of well-being with a renewed sense of purpose.

The Impact

Individuals with autism spectrum disorder face significant challenges entering the workforce; yet research in this area is limited and the issues are poorly understood. In this systematic review, empirical peer-reviewed studies on employment programmes, interventions and employment-related outcomes in individuals with autism spectrum disorder over 18 years with and without intellectual disability were identified and evaluated. The review was prefaced by a summary of previous systematic reviews in the area. Web of Science, Medline, PsychINFO, ERIC and Scopus databases were systematically searched through to October 2015. From 32,829 records identified in the initial search, 10 review and 50 empirical articles, comprising N = 58,134 individuals with autism spectrum disorder, were included in the review. Selected articles were organised into the following themes: employment experiences, employment as a primary outcome, development of workplace skills, non-employment-related outcomes, assessment instruments, employer-focused and economic impact. Empirical studies were limited by poor participant characterisation, small sample size and/or a lack of randomisation and use of appropriate controls. Poor conceptualisation and measurement of outcomes significantly limited study quality and interpretation. Future research will require a multidisciplinary and multifaceted approach to explore employment outcomes on the individual, the family system, co-workers and the employer, along with the impact of individual differences on outcome.

Financial literacy is necessary skill for life that could be improved through financial education. To enhance financial education, it is important to examine more deeply how students' financial knowledge and personal background affects their views on personal finance issues and financial decision making. This study analyzing the questionnaire survey results of 522 university students to assess the relationships between the financial literacy and students' financial opinions and choices; and the impact of educational and demographical characteristics to the participants' financial literacy, opinions and choices. Results of regression analyze show that statistically significant impact on the financial literacy have factors as gender, nationality, academic discipline, and financial choices and opinion, as holding a debit card, a bank loan, plan the financial affairs in advance on a daily basis and an interest to get more information about financial services and monetary affairs. Students studying in the science or mathematics oriented subjects have more knowledge in finance, especially male students. These results of study enable to develop financial education and give the direction for future research.

AbstractIntroduction. The COVID-19 is the name of an infectious disease caused by a new strain of coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). It was first diagnosed in December 2019 in patients in Wuhan City, Hubei Province, China. The symptoms are dominated by features of respiratory tract infections, in some patients with a very severe course leading to respiratory failure and, in extreme cases to death. Due to the spread of the infection worldwide, the WHO declared a pandemic in March 2020.Aim. An investigation of the impact of social isolation introduced due to the coronavirus pandemic on selected aspects of life. The researchers focused on observing changes in habits related to physical activity and their connections with people’s subjective well-being and emotional state.Material and methods. The study was carried out within the international project of the group „IRG on COVID and exercise”. The research tool was a standardized questionnaire.Results. Based on the data collected and the analysis of the percentage results, it can be observed that the overwhelming majority of people taking up physical activity reported a better mood during the pandemic. However, statistical tests do not confirm these relationships due to the small sample size.Conclusions. Isolation favours physical activity. Future, in-depth studies, by enlarging the population group, are necessary to confirm the above observations.

AbstractThe aims of this systematic review and meta-analysis were to describe prevalence of cardiovascular disease in gout, compare these results with non-gout controls and consider whether there were differences according to geography. PubMed, Scopus and Web of Science were systematically searched for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded, as were reviews, editorials and comments. Where possible meta-analysis was performed using random-effect models. Twenty-six studies comprising 949,773 gout patients were included in the review. Pooled prevalence estimates were calculated for five cardiovascular diseases: myocardial infarction (2.8%; 95% confidence interval (CI)s 1.6, 5.0), heart failure (8.7%; 95% CI 2.9, 23.8), venous thromboembolism (2.1%; 95% CI 1.2, 3.4), cerebrovascular accident (4.3%; 95% CI 1.8, 9.7) and hypertension (63.9%; 95% CI 24.5, 90.6). Sixteen studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases. There were no identifiable reliable patterns when analysing the results by country. Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. Future research is needed to investigate the link between gout, hyperuricaemia and increased cardiovascular risk and also to establish a more thorough picture of prevalence for less common cardiovascular diseases.

The Impact

Financial well-being describes when people feel able to meet their financial obligations, feel financially secure and are able to make choices that benefit their quality of life. Financial strain occurs when people are unable to pay their bills, feel stressed about money and experience negative impacts on their quality of life and health. In the face of the global economic repercussions of the COVID-19 pandemic, community-led approaches are required to address the setting-specific needs of residents and reduce the adverse impacts of widespread financial strain. To encourage evidence-informed best practices, a provincial health authority and community-engaged research centre collaborated to conduct a rapid review. We augmented the rapid review with an environmental scan and interviews. Our data focused on Western Canada and was collected prior to the pandemic (May–September 2019). We identified eight categories of community-led strategies to promote financial well-being: systems navigation and access; financial literacy and skills; emergency financial assistance; asset building; events and attractions; employment and educational support; transportation; and housing. We noted significant gaps in the evidence, including methodological limitations of the included studies (e.g. generalisability, small sample size), a lack of reporting on the mechanisms leading to the outcomes and evaluation of long-term impacts, sparse practice-based data on evaluation methods and outcomes, and limited intervention details in the published literature. Critically, few of the included interventions specifically targeted financial strain and/or well-being. We discuss the implications of these gaps in addition to possibilities and priorities for future research and practice. We also consider the results in relation to the COVID-19 pandemic and its economic consequences.

Abstract The past decade has been marked by increased awareness concerning employment discrimination against gays and lesbians. Yet, to the author’s knowledge, there has been limited research regarding the response of Canadian labour organizations to the workplace needs of gay and lesbian members. Limitations of these previous studies include small sample size, lack of theoretical framework, and the absence of empirical testing of hypotheses. The present study builds on these works through the use of Craig’s model, the inclusion of multi-disciplinary research, and the empirical testing of data collected from more than 240 Canadian collective agreements. Key findings include that larger, public sector bargaining units with equality clauses in their collective agreements were most likely also to contain clauses that prohibited discrimination based on sexual orientation. The paper concludes with suggestions for future research.
