The COVID-19 Pandemic and the Environment in the Asia Pacific
Authors: Huang Hao 
Published: May 2021

The COVID-19 pandemic has exposed the consequences of political and ecological choices that have been made and continue to be made in the Asia Pacific. Over recent decades, the region’s rapid urbanization and industrialization have played a significant role in dynamic national economic development, a rapid rise in per capita income and the establishment of some of the world’s fastest-growing cities. Development has, however, come at a heavy price: planetary-health experts believe that a byproduct of human intrusion into remote wilderness areas has been a sharp uptick in environmental degradation and zoonotic diseases such COVID-19. Moreover, people living with poor air quality are more susceptible to this virus, and airborne particulate matter may even help to spread the virus. A study conducted by the Harvard University T.H. Chan School of Public Health has confirmed that there is a statistical correlation between high levels of air pollution and increased Covid-19 mortality rates.

Authors: De Freitas Carla , Calanca Gabriela , Ilias Elias Jirjoss , Bezerra Arthur Sousa 
Published: May 2021

Introduction: COVID-19, caused by the new coronavirus or SARSCoV-2, has a high capacity for dissemination, which brings about an emergency scenario in public health. It manifests itself in a multifaceted manner, with a great variability in the profile of the affected population, which may be associated with biological, social and economic factors.
Objective: To know the epidemiological profile of the population affected by COVID-19, in order to promote better assistance.

Methods: This is a literature review, starting in 2020, using the SciELO, PubMed, Google Scholar, DATASUS databases and the website of the Brazilian Institute of Geography and Statistics (IBGE).

Results: Studies show a higher prevalence of SARS-CoV-2 infection in men, in the age group after the fourth decade of life and among whites.

Discussion: The first studies showed a prevalence of coronavirus infection in males. One of the hypotheses drawn was that men present more cardiopulmonary diseases and smoke more. Another study shows that women's lower susceptibility to infection is due to the X chromosome and sex hormones, which are essential for the innate and adaptive immune response. As for the age group, most studies show a higher prevalence after the fourth decade of life, due to increased expression of angiotensin 2 receptors (ACE2), hormonal changes in aging and associated comorbidities.

Conclusion: Studies show with greater assertiveness a predominance of involvement by COVID-19 in males, individuals from the fourth decade of life and in whites. However, it is important to investigate the epidemiological profile in order to offer better assistance and prevention.

Rota-Baxter operators and Bernoulli polynomials
Authors: Gubarev Vsevolod 
Published: May 2021

Abstract
We develop the connection between Rota-Baxter operators arisen from algebra and mathematical physics and Bernoulli polynomials. We state that a trivial property of Rota-Baxter operators implies the symmetry of the power sum polynomials and Bernoulli polynomials. We show how Rota-Baxter operators equalities rewritten in terms of Bernoulli polynomials generate identities for the latter.
Entropy in Thermodynamics: from Foliation to Categorization
Authors: Kycia Radosław A. 
Published: May 2021

AbstractWe overview the notion of entropy in thermodynamics. We start from the smooth case using differential forms on the manifold, which is the natural language for thermodynamics. Then the axiomatic definition of entropy as ordering on a set that is induced by adiabatic processes will be outlined. Finally, the viewpoint of category theory is provided, which reinterprets the ordering structure as a category of pre-ordered sets.
Circulant matrices with orthogonal rows and off-diagonal entries of absolute value 1
Authors: Contreras Daniel Uzcátegui , Goyeneche Dardo , Turek Ondřej , Václavíková Zuzana 
Published: May 2021

Abstract
It is known that a real symmetric circulant matrix with diagonal entries d ≥ 0, off-diagonal entries ±1 and orthogonal rows exists only of order 2d + 2 (and trivially of order 1) [Turek and Goyeneche 2019]. In this paper we consider a complex Hermitian analogy of those matrices. That is, we study the existence and construction of Hermitian circulant matrices having orthogonal rows, diagonal entries d ≥ 0 and any complex entries of absolute value 1 off the diagonal. As a particular case, we consider matrices whose off-diagonal entries are 4th roots of unity; we prove that the order of any such matrix with d different from an odd integer is n = 2d + 2. We also discuss a similar problem for symmetric circulant matrices defined over finite rings ℤ
m
. As an application of our results, we show a close connection to mutually unbiased bases, an important open problem in quantum information theory.

Authors: Xie Hong-Jie , Cui Fan , Shuang Wei-Bing 
Published: May 2021

Abstract

Objective
To explore the clinical effect of perioperative nursing guided by the concept of enhanced recovery after surgery and summarize them.

Methods
Pubmed, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang Database, and VIP Database were searched to obtain the relevant literature involving enhanced recovery after surgery (ERAS) guidance, obtain the effective clinical data, review the reports in literature, and obtain the effective scheme.

Results
Compared with the traditional nursing program, perioperative nursing principles guided by the concept of ERAS provide more accurate nursing care to patients and reduce the occurrence of intraoperative stress events through comprehensive nursing measures such as preoperative pre-rehabilitation measures, intraoperative body temperature and fluid management, postoperative analgesia, prevention of nausea and vomiting, early mobilization, catheter nursing, and better out-of-hospital follow-up.

Conclusions
Perioperative nursing principles guided by the concept of ERAS can significantly reduce the incidence of perioperative complications, shorten the hospital stay of patients, and promote postoperative rehabilitation of patients. The transformation and implementation of this concept can bring significant benefits to hospitals, medical care, and patients.
Effects of mother–child interaction on school adaptation of children according to maternal depression
Authors: Lee Hanna , Han Jeong-Won 
Published: May 2021

Abstract

Objective
Factors influencing school adaptation of school-aged children include both executive function (EF) and parent–child interaction. This study aims to investigate the developmental trajectory of mother–child interaction longitudinally using latent growth model analysis.

Methods
A longitudinal descriptive survey study was conducted. The participants comprised of 1,614 mothers and school-aged children, who participated in the Panel Study on Korean Children (6th–8th panel surveys). A model was designed and analyzed using latent growth modeling to estimate the pattern of change over time.

Results
In the group where the maternal depression was within the normal range, only the path by which the change rate of mother–child interaction affected school adaptation of children was statistically nonsignificant (t = 1.007, p = 0.314). In the group where maternal depression was mild or higher, only the paths by which the initial value of mother–child interaction affected EF difficulty (t = −2.75, p = 0.032) and EF difficulty affected school adaptation (t = −7.876, p < 0.001) were statistically significant.

Conclusions
This study confirms the research models developed by dividing mother–child interaction into two groups according to depression levels (i.e., normal range and mild or higher-level depression). The findings provide a basis for construction of individualized interventions.

Authors: He Yue-Yue , Yin An-Chun 
Published: May 2021

Abstract

Objective
This study aimed to investigate the status quo of family care degree, stigma and psychosocial adaptation of the patients with Parkinson’s disease (PD), and discuss the effects of family care degree on stigma and psychosocial adaptation among the patients with PD.

Methods
This study was conducted between September 2018 and April 2019 on patients with PD who were admitted to a Tertiary Grade A hospital in Dalian city. A total of 246 PD patients were investigated by convenience sampling method using self-designed general information questionnaire, along with family care index (APGAR), 24-item Stigma Scale for Chronic Illness (SSCI), and Psychosocial Adjustment Scale (PAS) for PD. And patients were divided into two groups according to the level of family care degree and compared with stigma and psychosocial adaptation.

Results
The total score of family care for patients with PD was 6.97 ± 2.46, family function was good in 132 cases (53.7%), moderate barrier in 92 cases (37.4%), and severe barrier in 22 cases (8.9%). The scores of stigma and psychosocial adaptability and their dimensions in the group with high degree family care were higher than the low degree group.

Conclusions
The overall level of family care for PD patients was poor. Improving family care degree can help patients with PD to reduce stigma and improve psychosocial adaptation.
Facilitating the employment of people with mental health difficulties in Ireland
Authors: Tighe Margaret , Murphy Caroline 
Published: May 2021

Abstract
The promotion of practices supporting positive mental health at work is increasingly important on employers’ agendas. However, within the HRM literature there is a relative dearth of research on how employers can facilitate reintegration into the workplace or first-time employment for employees with mental health issues. Publicly funded supports are emerging as a strategy that can provide targeted supports to both workers and employers. This paper aims to investigate the effectiveness of this approach by undertaking triadic research with employers, healthcare professionals, and workers using the service in the Irish context. We make recommendations regarding the enhancement of opportunities currently available to those with a mental health difficulty to return to and remain in employment. The paper contributes to our understanding of the nature of supports required to successfully facilitate employing or re-integrating those with a mental health disability or history of mental health problems into the workplace.
Perceived self-efficacy of students in a business simulation game
Authors: Dumblekar Vinod , Dhar Upinder 
Published: May 2021

Abstract
Self-efficacy is an individual's confidence in the personal ability to complete a task under specified conditions. Game self-efficacy is the belief of game players that they would win in a business simulation game competition. To understand the composites of such belief, an instrument of 30 statements was developed and statistically tested on 227 undergraduate students at the end of a business simulation game competition. The factor analysis produced eight factors of perceived game self-efficacy, namely, innovation, experimentation, conviction, openness, focus, proactivity, conceptualisation and determination. These factors have significant research implications for goal-oriented behaviour, goal setting and performance enhancement at work and in games and competitions, and in developing simulation games.
Multilateral teaching in physical education improves resilience and self-efficacy in adolescents and could help reduce bullying behaviors
Authors: Greco Gianpiero 
Published: May 2021

Abstract
Youth with higher levels of resilience and self-efficacy are less likely to engage in aggressive behaviors or be victims of bullying. Previous anti-bullying approaches have often achieved no reduction in bullying behavior. Thus, the aim of this study was to examine the effect of 12 weeks of extracurricular multilateral teaching on the risk for students (aged 14–16 years) to be involved in bullying. Sixty male students were allocated to an experimental group (n = 30) that performed psychoeducational activities combined with physical exercise training and team games (90 min, 2d · week–1) or a control group (n = 30). Before and after the intervention, we used the Child and Youth Resilience Measure (CYRM-28) to assess individual capacities and resources, relationship with primary caregiver, contextual factors, and total resilience; and the Self-Efficacy Questionnaire for Children (SEQ-C) to measure academic, social, emotional, and total self-efficacy. Four participants from the experimental group withdrew. Significant improvements of crucial relevance were found for the resilience and self-efficacy scales (p < 0.05) in the experimental group. We found that multilateral teaching may improve resilience and self-efficacy in adolescents and make them less likely to engage in aggressive behavior or be bullied. Multilateral teaching should be considered an effective alternative to the anti-bullying approach, highlighting the crucial role of physical education teachers in the promotion of proactive educational strategies to reduce bullying behaviors.
How football fans perceive sports heroes – The case of Israel
Authors: Levental Orr , Nudelman Shira Ben-Amram 
Published: May 2021

Abstract
Background: Hero-making and hero-worship are common in human society. Yet despite the universal appeal of heroes, the features attributed to these figures and the attitudes toward them change depending upon the circumstances. Heroes have been the topic of extensive discussion in the academic literature. Nevertheless, little research attention has been directed at sports heroes. Examining soccer heroes is of special importance, particularly in view of soccer’s popularity across the globe and the celebrity status of top soccer stars.
Purpose: The objective of this paper is to examine and map the defining features of soccer heroes as subjectively perceived by their fans.
Methods: We conducted a qualitative study that entailed semi-structured interviews with 18 young Israeli soccer fans as well as content analysis of fan chants.
Results: The research findings indicate that fans attribute special importance to three main characteristics that are not perceived as dominant among heroes in other contexts: loyalty to team and family, modesty and morality, and the ability to influence their surroundings. Based on the findings, the paper discusses the unique nature of soccer heroes in contrast to other elite players and the role played by these heroes for their fans.
A case study: the AFL as a positive institution
Authors: Densten Iain 
Published: May 2021

Abstract
The Australian Football League (AFL) is a leading professional sports organization within the multi-billion-dollar entertainment industry. This case study uses publicly available information to investigate the AFL in terms of its credentials as a positive institution using the good work model developed by Stansbury and Sonenshein (2012). The AFL has taken advantage of the economic rationalism and developed a corporate structure able to deliver a range of good work activities. For example, developmental programs that help players exceeding high community expectations. This study suggests that the good work model is beneficial for cognitive resources, normal functioning, regulatory focus, and impression formation. The AFL appears to answer Cameron et al. (2004) call to identify and enable flourishing and life-giving aspects of their organisation and, thus, represents a kind of positive institution. Finally, the study recognizes positive institutions as worthwhile but raises concerns about the uniqueness and lack of cultural research.
Individual knowledge of, perceptions about, and barriers to physical literacy (PL) in Malaysia
Authors: Zulkifli Ahmad Fahim , Danis Ajau 
Published: May 2021

Abstract
The purpose of this study was to evaluate individuals’ knowledge of, perceptions about, and barriers to promoting physical literacy (PL) in Malaysia. Random samples of 360 participants of different genders, ages, races, and education levels (aged 15–60 years) residing in Malaysia participated in this study, which was conducted on online platforms between the months of February and May, 2019. The participants’ knowledge was assessed using a modified Physical Literacy Knowledge questionnaire (PLKQ). Open-ended questions were also conducted to assess perceived perceptions and barriers to improving participants’ PL, thus strengthening the validity and reliability of data collection. Quantitative data were analyzed using descriptive statistics (e.g., means, SD) and the Pearson correlation coefficient, while the analysis of qualitative data involved the usage of the Interpretive Phenomenological Approach (IPA). The participants showed greater efficacy about standards in physical education and believed that PL is developed throughout one’s lifetime, with (M = 3.2, SD = 1.02) and (M = 3.78, SD = 1.02), respectively. Additionally, most participants pointed to the necessity of having specific skills and experience to develop PL among young people as the main barrier to improving PL in Malaysia, with (M = 3.25, SD = 1.02). This initial study will provide better direction for future researchers and educators to plan an intervention to increase PL among Malaysians and advocate for physical activity in individuals’ daily lives. Additionally, this study will be useful to inform future educators’ teaching practices, particularly in Malaysian schools.
