Today, leaders who contribute positively to businesses, as well as leaders who contribute negatively to businesses are increasing day by day. This study was conducted to investigate the mediating effect of burnout syndrome (BS) on toxic leadership (TL) and job satisfaction (JS) in businesses. The results of the SEM analysis, using a sample of 412 participants working in public hospitals in the Marmara region of Turkey in İstanbul, show that toxic leadership (TL) has negative effects on burnout syndrome (BS) and job satisfaction (JS). Although there are studies investigating the direct effect of toxic leadership on job satisfaction, there are limited data testing the burnout syndrome subcomponents on the effect of toxic leadership on job satisfaction. This research is critical in showing the mediating role of personal achievement burnout (PRS_Scc) dimension in the effect of toxic leadership (TL) on job satisfaction (JS) sub-components.

Bu çalışma, üniversite öğrencilerinin kişilik özelliklerinin ve siber güvenlik algıları üzerindeki etkilerini, çeşitli demografik değişkenlere göre inceleyerek farklılıkları ortaya çıkarmak için yapılmıştır. Araştırmanın evrenini Türkiye’de 2022-2023 yılları arasında Artvin Çoruh Üniversitesi Sağlık Hizmetleri Meslek Yüksek Okulunda eğitim alan öğrenciler oluşturmaktadır. Araştırmaya 387 öğrenci katılmış ve toplanan verile-rin SPSS 25 paket programı ile analiz edilmiştir. Öğrencilerin kişilik alt boyutlarından yumuşak başlılık boyutunun diğer kişilik tiplerine göre daha çok öne çıktığı ve nevro-tiklik boyutunun en düşük ortalamaya sahip olduğu görülmüştür. Siber güvenlik algısı ölçeğinin alt boyutlarından güvenilmeyenden kaçma boyutu en yüksek ortalamaya ve kişisel gizliliği koruma boyutunun en düşük ortalamaya sahip olduğu görülmüştür. Kişiliğin siber güvenlik algısının alt boyutlarından kişisel gizliliği koruma üzerindeki etkinin anlamlı olduğu görülmektedir. Kişilik alt boyutları ile siber güvenlik alt boyut-larından güvenilmeyenden kaçınma, önlem alma, ödeme bilgilerini koruma ve iz bı-rakmama boyutları arasında ilişkilerin anlamlı olmadığı görülmüştür. Kişilik özellikle-rinin ve siber güvenlik algısının alt boyutlarından hiçbiri öğrenim düzeyine göre de-ğişmediği görülmüştür. Öğrencilerin siber güvenlik alt boyutlarına ve kişilik alt boyut-larından dışa dönüklük, deneyime açıklık, nevrotiklik ve yumuşak başlılık düzeyleri-nin sosyal medya kullanım süresine göre değişmediği görülmüştür.

Purpose- Today, sustainability is a very important concept so that future generations can live comfortable life. In this, it is very important to produce products that are compatible with nature, to trust the product or service, and to purchase them. This study was conducted to determine the mediating role of green trust in health education students' green product purchasing preferences. Methodology- The sample of the study consists of 330 students studying in health departments. In the analysis of the data, descriptive, explanatory factor, confirmatory factor, correlation and regression analyzes were performed. Findings- There is a significant relationship between green product preference and all sub-dimensions of green product preference (attitude, environmental concern, environmental knowledge, subjective rules) and green product purchase intention. There is a significant relationship between green product preference and green product trust in all sub-dimensions of green product preference (attitude, environmental concern, environmental knowledge, subjective rules). There is a significant relationship between trust in green products and purchasing green products. In the sub-dimensions of students' green product preferences and green product preferences (attitude, environmental concern, environmental knowledge), the effect on green product purchasing also has a mediating effect on the level of trust in green products. However, subjective rules do not have a mediating effect on green product purchasing, nor does the level of trust in green products. Conclusion- This study aims to increase the awareness of green products and green trust, which is important in sustainability, on purchasing behavior, especially among young people, and to make this a behavior. Thus, a comfortable life can be provided for future generations. Keywords: Sustainability, green product, green trust, purchasing behavior, health students JEL Codes: M30, M31, Q01

Purpose- This study aims to investigate the effect of healthcare workers' emotional commitment on performance through organizational trust. Methodology- To examine the relationship between dependent and independent variables, data were collected through questionnaires with 420 health workers working in various hospitals. The collected data were analyzed with statistical methods used in social sciences. Findings- As a result of data analysis, it has been proven that continuance commitment and normative commitment have a positive effect on organizational trust. While continuance commitment had a positive effect on performance, normative commitment did not have a positive effect on performance. It has been observed that organizational trust has a positive effect on performance. While the partial mediating effect of continuance commitment on performance through an organizational trust has been proven, No positive effect of normative commitment on performance through the organizational trust was observed. Conclusion- This study shows that the emotional commitment of health workers, which is extremely important for health businesses, can increase their performance through organizational trust. This model can be a role model for other healthcare organizations and fills a research gap by providing an experimental study of repeated hospital management.
