Scholars frequently address the dyadic relationships between leaders and followers without observing the simultaneity of leadership and followership roles, particularly evident in middle managers. Their implicit and explicit challenges are the foci of this paper.

The purpose of this paper is to investigate the effect of round pits arrangement patterns on tribological properties of journal bearing. In this paper, the tribological behaviors of journal bearing with different arrangement patterns under lubrication condition were studied based on M-2000 friction and wear tester.

The friction and wear of journal bearing contact surface were simulated by ANSYS. The wear mechanism of bearing contact surfaces was investigated by the means of energy dispersive spectrum analysis on the surface morphology and friction and wear status of the journal bearing specimens by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometer (EDS). Besides, the wearing capacity of the textured bearing was predicted by using the GM (1,1) and Grey–Markov model.

As the loads increase, the friction coefficient of journal bearing specimens decrease first and then increase slowly. The higher rotation speed, the lower friction coefficient and the faster temperature build-up. The main friction method of the bearing sample is three-body friction. The existence of texture can effectively reduce friction and wear. In many arrangement patterns, the best is 4# bearing with round pits cross-arrangement pattern. Its texturing diameters are 60 µm and 125 µm, and the spacing and depth are 200 µm and 25 µm, respectively. In addition, the Grey–Markov model prediction result is more accurate and fit the experimental value better.

The friction and wear mechanism is helpful for scientific research and engineers to understand the tribological behaviors and engineering applications of textured bearing. The wear capacity of textured bearing is predicted by using the Grey–Markov model, which provides technical help and theoretical guidance for the service life and reliability of textured bearing.

Involvement of youth in electronic sports is increasing and outdoor sports are decreasing day by day. It not only affects their health but also leads them towards noncommunicable diseases. Risk of noncommunicable diseases is associated with physical inactivity and affects physical and mental health. It results in different personal and social implications. Therefore, the purpose of this paper is to highlight the importance of outdoor sports and risks of electronic sports for health.

The data for study is collected from 450 university students using purposive sampling technique. In order to measure outdoor sports, a four items instrument developed by Simon and Smoll (1974) is used. For electronic sports, instrument is adopted from Lemmens et al. (2009) and for health of youth, instrument by Bailis et al. (2003) is used. After reliability and validity check, structural equation modeling is used to analyze data.

The results reveal that perceived outdoor sports have significant positive impact on health, whereas electronic sports have negative impact on youth health that lead them to certain noncommunicable diseases. There is need to emphasize and encourage youth for outdoor sports and avoid indulging in esports that may lead to addiction.

Electronic games have various risks for the development of syndromes among younger generation. Awareness should be provided that physical activities are essential for healthy life and how risky be the esports for their health. This study may be helpful for government as well to reduce dependency of youth on technological devices and provide necessary recreation facilities to engage in. This research study validates that outdoor sports have significantly positive impact on health of youth and it reduces health related problems and destructive behaviors among youth.

Involvement of youth in electronic sports is increasing and outdoor sports are decreasing day by day. It not only affects their health, but also leads them toward non-communicable diseases. The present study examines the impact of esports and physical sports on youth health.

Healthcare providers are under pressure due to increasing and more complex demands for services. Increased pressure on budgets and human resources adds to an ever-growing problem set. Competent leaders are in demand to ensure effective and well-performing healthcare organisations that deliver balanced results and high-quality services. Researchers have made significant efforts to identify and define determining competencies for healthcare leadership. Broad terms such as competence are, however, inherently at risk of becoming too generic to add analytical value. The purpose of this study is to suggest a holistic framework for understanding healthcare leadership competence, that can be crucial for operationalising important healthcare leadership competencies for researchers, decision-makers as well as practitioners.

In the present study, a critical interpretive synthesis (CIS) was conducted to analyse competency descriptions for healthcare leaders. The descriptions were retrieved from peer reviewed empirical studies published between 2010 and 2022 that aimed to identify healthcare services leadership competencies. Grounded theory was utilised to code the data and inductively develop new categories of healthcare leadership competencies. The categorisation was then analysed to suggest a holistic framework for healthcare leadership competence.

Forty-one papers were included in the review. Coding and analysing the competence descriptions resulted in 12 healthcare leadership competence categories: (1) character, (2) interpersonal relations, (3) leadership, (4) professionalism, (5) soft HRM, (6) management, (7) organisational knowledge, (8) technology, (9) knowledge of the healthcare environment, (10) change and innovation, (11) knowledge transformation and (12) boundary spanning. Based on this result, a holistic framework for understanding and analysing healthcare services leadership competencies was suggested. This framework suggests that the 12 categories of healthcare leadership competencies include a range of knowledge, skills and abilities that can be understood across the dimension personal – and technical, and organisational internal and – external competencies.

This literature review was conducted with the results of searching only two electronic databases. Because of this, there is a chance that there exist empirical studies that could have added to the development of the competence categories or could have contradicted some of the descriptions used in this analysis that were assessed as quite harmonised. A CIS also opens for a broader search, including the grey literature, books, policy documents and so on, but this study was limited to peer-reviewed empirical studies. This limitation could also have affected the result, as complex phenomenon such as competence might have been disclosed in greater details in, for example, books.

The holistic framework for healthcare leadership competences offers a common understanding of a “fuzzy” concept such as competence and can be used to identify specific competency needs in healthcare organisations, to develop strategic competency plans and educational programmes for healthcare leaders.

This study reveals a lack of consensus regarding the use and understanding of the concept of competence, and that key competencies addressed in the included papers are described vastly different in terms of what knowledge, skills and abilities they entail. This challenges the operationalisation of healthcare services leadership competencies. The proposed framework for healthcare services leadership competencies offers a common understanding of work-related competencies and a possibility to analyse key leadership competencies based on a holistic framework.

This conceptual/study protocol paper provides important context around the role of sport in Australia where sport provides aspects of community agency through participation, organisation and volunteerism. It provides a descriptive analysis of how sport assists young people in developing physical and mental ”fitness” through its community orientation. However, it also provides discussion around the potential of a “generation lost” to sport as a consequence of the coronavirus disease 2019 (COVID-19) pandemic. The conceptual nature of this paper means that the data collection underpinning this research has not yet been conducted. However, given that we have applied for human research ethics along with having accrued sporting clubs and organisations eager to be involved in the research, we are planning to roll out this research by mid 2020. The design will be based on mixed methods approach whereby large-scale surveys together with focus groups and interviews will be central to the research data collection process. This research is unique given the nature of the time in which it exists. The last global pandemic was around 100 years ago when sport did not play such a significant role in society. Understanding the implications of the pandemic on young people and to the sporting clubs and organisations will be key in re-establishing sport as a central component of community agency towards the physical and mental health of young people. The urgency of understanding this is key to assisting the loss of potential young people to sport and the benefits that go with it to the individual, the community, and society as a whole.

Building on work that explores the relationship between individual beliefs and ability to recognize discrimination (e.g., Kaiser and Major, 2006), we examine how an adherence to beliefs about gender essentialism, gender egalitarianism, and meritocracy shape one’s interpretation of an illegal act of sexual harassment involving a male supervisor and female subordinate. We also consider whether the role of the gendered culture of engineering (Faulkner, 2009) matters for this relationship. Specifically, we conducted an online survey-experiment asking individuals to report their beliefs about gender and meritocracy and subsequently to evaluate a fictitious but illegal act of sexual harassment in one of two university research settings: an engineering department, a male-dominated setting whose culture is documented as being unwelcoming to women (Hatmaker, 2013; Seron, Silbey, Cech, and Rubineau, 2018), and an ambiguous research setting. We find evidence that the stronger one’s adherence to gender egalitarian beliefs, the greater one’s ability to detect inappropriate behavior and sexual harassment while gender essentialist beliefs play no role in their detection. The stronger one’s adherence to merit beliefs, the less likely they are to view an illegal interaction as either inappropriate or as sexual harassment. We account for respondent knowledge of sexual harassment and their socio-demographic characteristics, finding that the former is more often associated with the detection of inappropriate behavior and sexual harassment at work. We close with a discussion of the transferability of results and policy implications of our findings.

In this paper we examine the validity of the J-curve hypothesis in four Southeast Asian economies (Indonesia, Malaysia, the Philippines and Thailand) over the 1980–2017 period.

We employ the linear autoregressive distributed lags (ARDL) model that captures the dynamic relationships between the variables and additionally use the nonlinear ARDL model that considers the asymmetric effects of the real exchange rate changes.

The estimated models were diagnostically sound, and the variables were found to be cointegrated. However, with the exception of Malaysia, the short- and long-run relationships did not attest to the presence of the J-curve effect. The trade flows were affected asymmetrically in Malaysia and the Philippines, suggesting the appropriateness of nonlinear ARDL in these countries.

The previous research tended to examine the effects of the real exchange rate changes on the agricultural trade balance and specifically the J-curve effect (deterioration of the trade balance followed by its improvement) in the developed economies and rarely in the developing ones. In this paper, we address this omission.

This paper aims to replicate 148 anomalies and to examine whether the performance of the Korean market anomalies is statistically and economically significant. First, the authors observe that only 37.8% anomalies in the universe of the KOSPI and the KOSDAQ and value-weighted portfolios have t-statistics that exceed 1.96. When the authors impose a higher threshold (an absolute value of t-statistics of 2.78), only 27.7% of the 148 anomalies survive. Second, microcaps have large impacts. The results vary significantly depending on whether the sample included stocks in the KOSDAQ and whether value-weighted or equal-weighted portfolios are used. The results suggest that data mining explains large portion of abnormal returns. Any tactical asset allocation strategies based on market anomalies should be applied very cautiously.

We conducted a national study of the Collegiate Leadership Competition (CLC), which since inception in 2015, has included over 75 higher education institutions. The CLC brings students together in collaborative institution-based teams to compete with other teams in competitions to achieve goals and practice effective leadership skills. Our goal was to assess leadership capacity growth over the course of a four-month team practice period through the daylong inter-team competition and evaluate participant leadership assessed several months later. Results suggested students made significant and sustainable gains in leader-self-efficacy and short-term gains in leadership skill and motivation to lead. Our results also indicated the team’s coach played a significant role in student leadership development.

Leadership development programs for students in educational settings are proliferating in number and design. Curricular programs range from academic minors and certificates to doctoral programs in a variety of academic homes (e.g., education, business, healthcare). Co-curricular programs often take the form of drop-in workshops, day-long experiences, alternative spring breaks, service-learning trips, and other programs housed in student affairs and administrative offices (Guthrie & Jenkins, 2018). Moreover, the number of programs has steadily increased over the last 15 years from just under 1,000 in 2006 (Brungardt, et al., 2006) to more than 2,000 (ILA Program Directory, 2021). And while there is some commonality among the approach of these leadership programs in terms of content and delivery (see Harvey & Jenkins, 2014), vast differences exist in the structure and learning goals of student leadership programs compared to other social science disciplines. A potentially fruitful area in which to explore its effectiveness in supporting leadership development is the environment of competitive teams, where individuals work together as a group to compete against other teams. The purpose of our research was to investigate the degree to which such a competitive environment might support or detract from student leadership group, employing a potentially effective example of a formal program that utilizes the innovative approach of team competitions to motivate learning (the CLC).
