Background Wrestling is a physically and mentally demanding combat sport that requires discipline, focus, and emotional control. Although its physiological effects are well documented, its psychological benefits in adolescents remain underexplored. This study aimed to examine whether a short-term, non-competitive wrestling program could enhance psychological well-being, reduce sport anxiety, and strengthen resilience in adolescent boys. Methods Thirty sedentary male adolescents (aged 12-15 years) were randomly assigned to a wrestling training group (n = 15) or a control group (n = 15). The intervention consisted of six weeks of supervised wrestling sessions performed three times per week. Psychological well-being (WHO-5), sport anxiety (SAS-2), and resilience (BPRS) were assessed before and after the intervention using the validated Turkish versions of the scales. Two-way repeated-measures ANOVA was used to analyze group & times; time interactions. Results Participants in the wrestling group demonstrated significant improvements in well-being (p < 0.001) and resilience (p < 0.001), alongside marked reductions in total sport anxiety and its subdimensions (p < 0.001), compared with the control group. All effects were large (eta p & sup2; = 0.52-0.94). Conclusion A structured six-week wrestling program produced meaningful psychological benefits in adolescent boys. Regular participation in non-competitive wrestling may serve as an effective approach to promote well-being, emotional stability, and adaptive coping skills during early adolescence, supporting the preventive and developmental role of combat sports in youth mental health.

Karapınar Kocağ, Esra; Li, Yutong; Popescu, Cristina Raluca Gh.
Movements of labor across the world is an ongoing debate in the literature in terms of its drivers and results in sending and receiving areas. Skill composition of immigrant labor has been discussed by several papers, although they generally focused on visa policies or firm level productivity. However, this paper focuses on the relationship between immigrants’ educational attainment and government budgeting on research and development (R&D). Panel data analysis is applied for European countries, along with instrumental variable approach as a robustness check. Findings reveal that higher budget allocation for R&D is associated with higher skill level of immigrants within overall immigrant population. This finding is driven by young immigrants whose ages are between 25 and 34 and female immigrants in these countries, suggesting that this relationship varies among sub-groups of immigrants, which would have significant policy implications. Hence, the novel and original approach of the paper resides in the deciding factors of immigrants’ skill composition.

Popescu, Cristina Raluca Gh.; Karapınar Kocağ, Esra
To begin with, Sustainable Development Goals are of tremendous importance in all areas, being seen as vital aims in all domains, which makes them indispensable when it comes to addressing the particularities of the labour market these days. Subsequently, human resources occupy a distinctive and unique position when referring to the implications derived from targeting Sustainable Development Goals, especially in the context represented by the period specific to the COVID-19 pandemic and the international events that followed immediately after that. This study investigates the work motivation of individuals, and whether they would be willing to work more hours if they are paid. Motivation and attitudes towards working more hours might be affected by several factors, and they are important contributors to business performance. Not only business performance is to be affected, but this is also a part of Sustainable Development Goals where labour market conditions and productivity concerns are addressed, along with several other factors. Using the Quarterly Labour Force Survey from 2017 to 2022 that is conducted by Statistics South Africa, this study attempts to shed light on individual preferences for working more hours in the case of South Africa. Considering the dichotomous dependent variable, a binary response model is utilised to explore the determinants of such behaviour. Findings of the probit model reveal that socio-demographic factors such as gender, marital status, education level, and work experience are important indicators to explain this preference. More precisely, being female increases the likelihood of willingness to work more hours if paid by 1.1 percentage points, and being never married increases that probability by 2.7 percentage points. Within education categories, the highest coefficient in magnitude, having tertiary education decreases the probability of willingness to work more hours by 8.2 percentage points. As an important labour market indicator, one more year to commence working increases the probability of willingness to work more hours by 0.4 percentage points.
