Determinants of Competitive Advantage for Sport Firms: Using Public Big Data in Korea

This study examines the determinants of competitive advantage with respect to economic performance of sport firms. Logit regressions estimated dependent variables of economic performance measures based on sales per capita of firms. Determinants of competitive advantage were estimated by efficiency indicators, organization characteristic indicators, and industry classification indicators. Increase in efficiency was a significant determinant of competitive advantage as well as organizational type, size of human resource, diversification of products, and sales growth rate. Operationalizing competitive advantage as outperforming the market average and better than the top 10%, the logit regression model provides means for sport firms to analyze industry data to evaluate their own performance. In particular, including efficiency estimates showed practical significance for market analysis

Reference Dependent Preference and Fan Responses: A Text Analysis of YouTube Comments on K-League Highlights

PURPOSE This study examined whether K-league fans’ responses to game outcomes align with reference-dependent preference and loss aversion principles. METHODS We collected user comments from the 2023 K-league game highlights videos on YouTube. We identified each user’s supporting team and excluded neutral fans’ comments. Sentiment analysis using KoBERT was applied, and estimated sentiment scores served as dependent variables. We performed panel regression to test whether unexpected wins and losses generate positive and negative comments. RESULTS First, an unexpected win generates more positive comments, and an unexpected loss generates more negative comments; a reference-dependent preference exists. Second, the difference between the coefficient on upset win and the absolute value of the coefficient on upset loss is not statistically different; loss aversion does not exist. CONCLUSIONS The findings derive a deeper understanding of sports viewership and explain the difference between domestic and overseas sports fans. Also, the findings provide insights into the domestic professional sports business

Manager migration, learning-by-hiring, and cultural distance in international soccer

Research Summary: We investigate the international transfer of managerial know-how by analyzing manager migration patterns in the setting of international soccer. We characterize a country's managerial know-how by estimating a stochastic frontier model, which relates the country's soccer performance to socioeconomic and climatic conditions. We find evidence of learning-by-hiring in that hiring a migrant manager hailing from a high know-how country is beneficial to the destination country's performance. Larger cultural distance between the migrant manager and destination country reduces the effectiveness of learning-by-hiring, but this effect is moderated by the migrant manager's prior international experience. The transfer of managerial know-how contributes to the overall convergence of low-performing versus high-performing soccer countries. Managerial Summary: In this study, we ask whether firms in developing countries, which often suffer from having low-quality manage

The effect of physically or non-physically forced sexual assault on trajectories of sport participation from adolescence through young adulthood

Background Sexual assault is one of potential factors that may greatly affect an individuals sport participation. The purpose of this study is to investigate the effect of experiencing physically or non-physically forced sexual activity on trajectories of sport participation from adolescence to young adulthood. Methods This study used the National Longitudinal Study of Adolescent Health (Add Health) data. Group-based trajectory modeling was utilized to examine the effect of experiencing sexual assault on trajectories of sport participation from adolescence to young adulthood. Results A three-group trajectory model (high-stable group, high-decreasing group, and low-stable group) best fit sport participation among male participants and a two-group trajectory model (high-decreasing group and low-stable group) best fit sport participation among female participants. Both physically and non-physically forced sexual activity did not have significant effect on trajectories of sport participation among male participants. On the other hand, non-physically forced sexual assault significantly affected sport participation trajectory among female participants. Conclusions Special care is required in developing sport promotion program for women victims of non-physically forced sexual activity. The results of this study also suggest that group-based trajectory modeling is a useful technique to examine distinct trajectories of sport participation from adolescence through young adulthood

Phenotypic and Genomic Properties of Brachybacterium vulturis sp. nov. and Brachybacterium avium sp. nov.

Two strains, VM2412T and VR2415T, were isolated from the feces of an Andean condor (Vultur gryphus) living in Seoul Grand Park, Gyeonggi-do, South Korea. Cells of both strains were observed to be Gram-stain positive, non-motile, aerobic, catalase positive and oxidase negative. Growth was found to occur at 10-30°C, showing optimum growth at 30°C. The strains could tolerate up to 15% (w/v) NaCl concentration and grow at pH 6-9. The strains shared 99.3% 16S rRNA gene sequence similarity to each other but were identified as two distinct species based on 89.0-89.2% ANIb, 90.3% ANIm, 89.7% OrthoANI and 38.0% dDDH values calculated using whole genome sequences. Among species with validly published names, Brachybacterium ginsengisoli DCY80T shared high 16S rRNA gene sequence similarities with strains VM2412T (98.7%) and VR2415T (98.4%) and close genetic relatedness with strains VM2412T (83.3–83.5% ANIb, 87.0% ANIm, 84.3% OrthoANI and 27.8% dDDH) and VR2415T (82.8–83.2% ANIb, 86.7% ANIm, 83.9% OrthoANI and 27.2% dDDH). The major fatty acid of the two strains was identified as anteiso-C15:0 and the polar lipids consisted of phosphatidylglycerol, diphosphatidylglycerol, presumptively phosphatidylethanolamine and three unidentified glycolipids. Strain VR2415T also produced an unidentified phospholipid. The cell walls of the two strains contained meso-diaminopimelic acid as diagnostic diamino acid and the whole cell sugars were ribose, glucose, and galactose. The strains contained MK-7 as their predominant menaquinone. The genomes of strains VM2412T, VR2415T, and B. ginsengisoli DCY80T were sequenced in this study. The genomic G+C contents of strains VM2412T and VR2415T were determined to be 70.8 and 70.4 mol%, respectively. A genome-based phylogenetic tree constructed using an up-to-date bacterial core gene set (UBCG) showed that the strains formed a clade with members of the genus Brachybacterium, supporting their taxonomic classification into the genus Brachybacterium. Based on phenotypic and genotypic analyses in this study, strains VM2412T and VR2415T are considered to represent two novel species of the genus Brachybacterium and the names Brachybacterium vulturis sp. nov. and Brachybacterium avium sp. nov. are proposed for strains VM2412T (=KCTC 39996T = JCM 32142T) and VR2415T (=KCTC 39997T = JCM 32143T), respectively

Effects of C and N on high-temperature deformation behavior of 15Cr-15Mn-4Ni austenitic stainless steels

The effect of interstitial C and N atoms on high-temperature deformation behavior was investigated in 15Cr & ndash;15Mn & ndash;4Ni austenitic stainless steels containing 0.1 & ndash;0.3 wt% of either C or N. Single-hit compression tests were performed in the deformation temperature range 800 & ndash;1100 degrees C and the strain rate range 0.01 & ndash;1 s- 1. In both C-added (+C) and N-added (+N) steels, the high-temperature strength, i.e. mean flow stress, increased as the concentration of C or N increased. At the same level of C or N concentration, the mean flow stress, activation energy for high-temperature deformation, and degree of lattice expansion were larger in +N-steels than in +Csteels, whereas the dynamically recrystallized grain size and grain growth rate were larger and faster in +C-steels than in +N-steels. The higher strength of +N-steels over +C-steels at a wide range of temperatures was attributed to the stronger solid solution hardening effect of N atoms compared to C atoms. Dynamic recrystallization was relatively retarded in the +N-steels, because N atoms interacted strongly with grain boundaries.11Nsciescopu

Effects of Employees’ Extra-Role Behaviors on Organizational Performance: An Assessment of Minor League Baseball Team Front Offices

Global Alliance of Marketing and Management Associations (GAMMA). The purpose of this study was to examine the effects of employees’ extra-role behaviors on desired organizational outcomes in sport. An assessment of innovative work behaviors and organizational citizenship behaviors of Minor League Baseball team front office employees was conducted as organizations planned for an upcoming season. An empirical model controlling for extraneous factors was developed and tested. Results revealed organizational citizenship behaviors of front office employees positively affected attendance during the season for Triple-A and Double-A level franchises. No significant effects between employees’ organizational citizenship and team attendance was seen in lower level teams. Employees’ innovative work behaviors were not significantly related to team attendance. The current study indicates that these sport organizations may not be benefitting from the behaviors it celebrates in its employees, namely the extra role behaviors. This study has demonstrated that context specific factors can substantially alter expected employee and organizational behaviors
