This study examined the home advantage effect in decisive National Basketball Association Conference Finals and Finals series playoff games from 1979 to 2019 (the 3-point shot era). We also examined the potential contribution of various offensive- and defensive-based skills and whether these skills mediated the relationship between game status (decisive vs. nondecisive) and outcome (win vs. loss). Overall, we found evidence of a home court advantage with the home team winning 63% of the decisive playoff games and 66% of the nondecisive playoff games. After adjusting for multiple comparisons and regular season win percentage, the home team had significantly more defensive rebounds and steals in Game 5 when trailing 3–1 going into that game. Mediation analyses did not reveal any significant findings when examining the impact of decisive game status on performance through offensive and defensive skills, thus suggesting there are other explanations for the home advantage effect.

Abstract Introduction Home court advantage (HCA) in the National Basketball Association (NBA) is well-documented, yet the co-occurring drivers responsible for this advantage have proven difficult to examine in isolation. The Coronavirus disease (COVID-19) pandemic resulted in the elimination of crowds in ~50% of games during the 2020/2021 NBA season, whereas travel remained unchanged. Using this ‘natural experiment’, we investigated the impact of crowds and travel-related sleep and circadian disruption on NBA HCA. Methods 1080 games from the 2020/2021 NBA regular season were analyzed using mixed models (fixed effects: crowds, travel; random effects: team, opponent). Results In games with crowds, home teams won 58.65% of the time and outrebounded (M=2.28) and outscored (M=2.18) their opponents. In games without crowds, home teams won significantly less (50.60%, p = .01) and were outrebounded (M=-0.41, p < .001) and outscored (M=-0.13, p < .05) by their opponents. Further, the increase in home rebound margin fully mediated the relationship between crowds and home points margin (p < .001). No significant sleep or circadian effects were observed. Discussion Taken together, these results suggest that HCA in the 2020/2021 NBA season was predominately driven by the presence of crowds and their influence on the effort exerted by the home team to rebound the ball. Moreover, we speculate that the strict NBA COVID-19 policies may have mitigated the travel-related sleep and circadian effects on the road team. These findings are of considerable significance to a domain wherein marginal gains can have immense competitive, financial, and even historical consequences.

The Impact

In sports, home advantage describes the benefits that the home team enjoys over the away team. These benefits are manifested due to cognitive effects that the local home crowd may have over the competitors or umpires, advantages of playing in familiar situations resulting in better adaptability, specific rules favouring the home team directly or indirectly, the away teams often suffer from jet lag due to change in time zones or from the tenacity of travel, etc. In this paper, various exploratory data visualization techniques have been utilized to observe the impact of home advantage in professional basketball association league NBA- National Basketball Association. Further the factors attributing to home advantage in sports are analysed. It was observed that when the team had performed well at home games, the results reflected the same for away games; however, home advantage was still distinctively visible.

The interest in sports in the world is increasing in parallel with the developments in communication technology, . As a result of this increase, the number of researches conducted on sports industry and sport management has also showed an increase. The field of sport that attracts the most attention worldwide is football. Data analysis and statistical research are also included in football researches in this field of sports that intertwines with different fields of science such as football management, finance and sports industry. In addition to the econometric measurement methods on the related researches, the variables affecting the results of the competition and the statistical analyzes that determine the impact strength of these variables are more abundant in the literature. As a result of the competitions, the variables affecting the results of a competition attract the attention of football players, technical team, fans, media organizations and sports managers. When it comes to this study,  it was planned to statistically determine the effect of the first goal in the European football leagues on the results of the match. From 5 countries in Europe Spain, France, Germany, England and Italy in particular, data belonging to the matches of the teams in which they were the home team between 2014-2017 seasons was used. A total of 5478 matches were analyzed in which 1140 matches were from Spain,  918 from Germany, 1140 from France, 1140 from England and 1140 from Italy. The relationship between the first goal and the match result was determined by the chi-square independence test. SPSS 24.0 package program was used in the analysis. The first goal independent variable in the study was examined and it was found that there was a relationship between the first goal and the match results (p <0.05). As far as  results of the research data are concerned, it was found that there was a relationship between the first goal scored and the match results  of the 5 major European  football leagues when the teams were the home teams  during the three seasons. Accordingly, the importance of the first goal was demonstrated by this study.

Interest in abusive supervision (Tepper, 2000) has increased due to its serious personal andorganizational costs. As such, there is a need for additional studies that identify the individuals’ factorsthat can minimize the adverse effects of abusive supervision.Specifically, we predict employee self-esteem as a buffer of the relationship between abusivesupervision, organizational trust and in-role behaviors. Additionally, we suggest organizational trustas a possible mechanism linking abusive supervision to in-role behaviors. Our model was exploredamong a sample of 201 supervisor-subordinate dyads from different organizational settings. The resultsof the moderated mediation analysis supported our hypotheses. That is, abusive supervision wassignificantly related to in-role behaviors via organizational trust when employees’ self-esteem waslow, but not when it was high. These findings suggest that self-esteem buffers the impact of abusivesupervision perceptions on organizational trust, with consequences for performance.

This study tries to examine the influence of work-to-family conflict and job satisfaction on the relationship between supervisor support and the psychological wellbeing of 290 administrative workers at the University of Cape Coast, Ghana. The results of the parallel mediation analysis showed that supervisor support had a significant positive impact on employees&rsquo; psychological wellbeing and job satisfaction and also had a significant negative impact on employees&rsquo; work-to-family conflict. Moreover, the study found a direct positive effect of employees&rsquo; job satisfaction on their psychological wellbeing but did not find a direct negative effect of employees&rsquo; work-to-family conflict on their psychological wellbeing. In addition, job satisfaction mediated the association between supervisor support and the psychological wellbeing of employees. The study however found no evidence of the mediating influence of work-to-family conflict on the relationship between supervisor support and employees&rsquo; psychological wellbeing. Both theoretical and practical implications were further discussed.

This article aims to understand the impact of the relationship between operations leader employee orientation (LEO) and leader information orientation (LIO) on leader long-term orientation (LLTO). The relationship is mediated by leader inclusivity orientation (LINCO) and moderated by leader technology orientation (LTO). The data were collected from business leaders who had more than 15 years of experience in the domain of supply chain, operations, and manufacturing. The total number of questionnaires sent to respondents was 620. Authors received 446 filled responses, out of which 360 responses were usable. The response rate was 58 percent. Moderated mediation analysis was performed to analyze the data and to test the proposed hypothesis. The findings revealed that the relationship between LEO LIO has a significant effect on LLTO. The relationship was positively mediated by LINCO. Further, LTO was found to be significantly related to LEO–LINCO–LTO and LIO–LINCO–LTO in a way that the relationship is strong when LTO is high and weak when LTO is low.

Background Among patients with heart failure, women have worse functional status than do men, but little research has focused on determining factors that influence functional status in either sex. Objectives To compare factors that influence functional status in men and women with heart failure and to test whether depressive symptoms mediate the relationship between physical symptoms and functional status. Methods A cross-sectional, descriptive study design was used. A total of 231 patients, 133 men and 98 women, were recruited from an inpatient heart failure clinic in South Korea. Functional status (the Korean Activity Scale/Index), physical symptoms (the Symptom Status Questionnaire), depressive symptoms (the Beck Depression Inventory), and situational factors (living status, socioeconomic status) were measured. Hierarchical multiple regression and mediation analysis were used for data analysis. Results Women (mean score, 24.5; SD, 17.3) had worse functional status than did men (mean score, 31.9; SD, 20.1; P = .004). Dyspnea on exertion (β = −0.16), ankle swelling (β = −0.19), fatigue (β = −0.20), and depressive symptoms (β = −0.19) were independently associated with functional status in women, whereas only dyspnea on exertion (β = −0.30) influenced functional status of men in hierarchical multiple regression analysis. Mediation analysis indicated that depressive symptoms mediated the relationship between physical symptoms and functional status in women with heart failure, but not in men. Conclusions Distinct physical and psychological symptoms influence functional status in women with heart failure. A systematic multidimensional intervention may be required to target depressive symptoms to improve functional status in women with heart failure.

The Relationship

Nontraditional scheduling in the National Football League (NFL) has created variation in the rest/preparation time among opponents. Using data from the 2011 to 2015 NFL seasons, regression analysis examines the impact of differential rest and preparation periods among teams on the probability of the home team winning and on the number of points scored in a particular contest. Results show that the probability of winning a game for the home team and the total number of points scored in a game are impacted by different rest combinations between opponents. These impacts are sensitive to the familiarity among opponents and the travel patterns of the visiting team.

PurposeThe purpose of this paper is to investigate the impact of e-government usage on citizen engagement during the COVID-19 crisis in China, in relation to the mediating role of how citizens perceive the government. A model was also proposed to explain the relationship between e-government usage during the COVID-19 crisis and the mediating role that different perceptions of government play in influencing citizens level of engagement.Design/methodology/approachThe research model was tested empirically through a survey conducted online with 866 research participants, comprising of Chinese citizens from three large cities, which include Hefei, Shanghai and Nanjing.FindingsThe results in structural equation modeling showed that e-government usage has a significant positive influence on citizens' perception about trust in government, government transparency and government reputation but not significant influence on citizens' engagements. However, an indirect relationship was found out in the mediation analysis. There was also a significant relationship between the different perceptions of government. Mediation analysis showed that all the different perceptions of government mediate the relationship between e-government usage and citizens' engagements during the COVID-19 crisis. The single mediation pathways were found to be most effective mediators, identifying citizens' perception about trust in government to be the most effective mediator.Originality/valueThis study filled the gap in literature by examining how e-government usage by Chinese citizens during the COVID-19 crisis helped influence their attitude and behavior. Specifically, this study is one of the first to integrate citizens' usage of e-government and citizens' engagement through the different citizens' perceptions of government such as trust in government, transparency of government and government reputation in a non-liberal country.

ABSTRACTThe impact of inherited genetic variation on gene expression in humans is well-established. The majority of known expression quantitative trait loci (eQTLs) impact expression of local genes (cis-eQTLs). More research is needed to identify effects of genetic variation on distant genes (trans-eQTLs) and understand their biological mechanisms. One common trans-eQTLs mechanism is “mediation” by a local (cis) transcript. Thus, mediation analysis can be applied to genome-wide SNP and expression data in order to identify transcripts that are “cis-mediators” of trans-eQTLs, including those “cis-hubs” involved in regulation of many trans-genes. Identifying such mediators helps us understand regulatory networks and suggests biological mechanisms underlying trans-eQTLs, both of which are relevant for understanding susceptibility to complex diseases. The multi-tissue expression data from the Genotype-Tissue Expression (GTEx) program provides a unique opportunity to study cis-mediation across human tissue types. However, the presence of complex hidden confounding effects in biological systems can make mediation analyses challenging and prone to confounding bias, particularly when conducted among diverse samples. To address this problem, we propose a new method: Genomic Mediation analysis with Adaptive Confounding adjustment (GMAC). It enables the search of a very large pool of variables, and adaptively selects potential confounding variables for each mediation test. Analyses of simulated data and GTEx data demonstrate that the adaptive selection of confounders by GMAC improves the power and precision of mediation analysis. Application of GMAC to GTEx data provides new insights into the observed patterns of cis-hubs and trans-eQTL regulation across tissue types.
