Job demands-resources model and burnout in physical education teaching: A mixed-method sequential explanatory study Kiremitçi, Olcay; Boz, Berkcan; Çakır Yıldız, Lale ACKGROUND: While literature includes a number of studies about burnout in teaching, investigations on teaching fieldspecific perspective remain limited. Research is needed to improve practical implications based on structured theoretical models and methodological basis that focusses on the unique environment of PE teaching field and causal factors behind burnout. OBJECTIVE: The present study aimed to examine burnout among physical education (PE) teachers based on the job demands-resources (J-DR) model. METHODS: A sequential explanatory mixed design was conducted in the study. 173 teachers replied to questionnaires, of which 14 teachers thereafter participated in semi-structured interviews. Demographic information form, Maslach Burnout Inventory, and J-DR scale for PE teachers were used, as well as an interview form. 173 teachers were first asked to report demographic information, and score Maslach Burnout Inventory and J-DR scale. Then a subsample group (n = 14) was identified/sampled for a semi-structured interview. Canonical correlation and constant comparative analysis were used to unpack the data. RESULTS: Teachers' states of burnout varied, and physical, organisational, and socio-cultural resources were closely related with burnout levels. Demands that cause pressure on burnout were determined as paperwork and bureaucracy, student-related factors, and pandemic-related experiences. In addition to supporting the general model, specific J-DR factors for PE teaching were observed that is linked with burnout. CONCLUSION: J-DR factors that might lead to negative conditions in the teaching environment should be considered, and field-specific factors should be focused on through arrangements to increase teaching efficiency and improve the quality of PE teachers' professional life.

Relationships Between Internal Marketing and Job Performance Mediated by Psychological Ownership Among Fitness Centers' Employees: An Empirical Analysis Using PLS-SEM Techniques Yıldız, Kadir; Yıldız, Süleyman Murat; Polat, Ercan This study examined the relationship between internal marketing and job performance as the mediating variable of psychological ownership by focusing on fitness center trainers. The convenience sampling technique was used in the study. Data were collected from fitness centers engaged in business in Turkey. The research group consists of 177 fitness center trainers. The model test with Partial Least Squares (PLS) was used as the analysis technique in the study. The results support the model proposal that fitness center trainers' internal marketing experiences play a role in job performance both directly and indirectly through psychological ownership. Therefore, fitness centers should give importance to internal marketing to improve the experiences of their employees and obtain corporate ownership. This will increase employees' job performance, and, consequently, customer satisfaction will be positively affected.

Acute effect of moderate and high-intensity interval exercises on asprosin and BDNF levels in inactive normal weight and obese individuals Ceylan, Halil İbrahim; Öztürk , Mehmet Ertuğrul; Öztürk, Deniz; Saygın, Özcan This study aimed to examine the acute effects of moderate-intensity aerobic and high-intensity interval exercise protocols on Asprosin and Brain-Derived Neurotrophic Factor (BDNF) levels in inactive normal weight and obese individuals. A total of 20 male individuals aged 18-65 years, ten normal weight (NW) (Body Mass Index (BMI): 18.5-24.99 kg/m2) and 10 obese (Ob) (BMI: 24.99-35.00 kg/m2) participated in this study, voluntarily. Moderate aerobic exercise (AE) (main circuit 30 min, between 40 and 59% of Heart Rate Reserve: HRR) and High-Intensity Interval exercise (HIIE) running protocols (main circuit 20 min, between 75 and 90% of the HRR for 1 min*10 times, and 1-min active rest at 30% of the HRR) was applied to the volunteer participants in the morning hours (08.00-10.00 a.m.), following the night fasting (at least 8-10 h) for at least 3 days between each other. Blood samples were collected from the participants before and immediately after each exercise protocol, and serum asprosin and BDNF hormone levels were determined by Enzyme-Linked Immunosorbent Assay" method. Basal serum asprosin was found to be significantly higher in the Ob group compared to the NW group (p < .001), while the basal serum BDNF hormone was found to be lower (p < 0.05). It was observed that the serum asprosin level of both groups decreased significantly after both AE and HIIE protocols (p < 0.05). In addition, there was a significantly higher decrease in serum asprosin level in the Ob group compared to the NW group after HIIE protocol. For the Ob group, serum BDNF level increased considerably after HIIE protocol compared to AE protocol (p < 0.05). Serum asprosin was found to be higher in the Ob group, while the serum BDNF was found to be lower. In addition, the acute exercises of different intensity significantly affected hormones that regulate appetite metabolism. In particular, it was observed that the HIIE protocol had a greater effect on the regulation of appetite (hunger-satiety) in the Ob group. This result can be taken into account when planning training programs for these individuals.

RELATIONSHIPS BETWEEN WORKPLACE MOBBING BEHAVIORS AND REVENGE THOUGHTS: EMPIRICAL RESULTS FROM HIGHER EDUCATION INSTITUTIONS

RELATIONSHIPS BETWEEN WORKPLACE MOBBING BEHAVIORS AND REVENGE THOUGHTS: EMPIRICAL RESULTS FROM HIGHER EDUCATION INSTITUTIONS Yıldız, Süleyman Murat; Güllü, Sevim Research on the relationship between mobbing in the workplace and thoughts of revenge in the literature is very limited. Therefore, this study aims to examine and better understand the relationships between these two variables. The sample for the study was collected from academics who worked in higher education institutions. Correlations and hierarchical regression analyzes were used to explore relationships between study variables, and the results show statistically significant and positive relationships between mobbing and thoughts of revenge. It is even noteworthy that bullying has a high level of influence on thoughts of revenge. The managerial and research implications and contributions of the study are discussed.
