  Özbek, Adem

  Every investment decision at the macro or micro scale carries with it the desire to profit. At this point, profit assumes the driving role and continuity of capital. Information assumes a crucial role in the realization of this role. The field of behavioral finance, which opens a different window to the finance literature, argues that investors do not act completely rationally in financial decisions. Behavioral finance argues that there are subconscious factors that affect information. This study aims to detect the factors of behavioral bias factors influencing the investment decisions of individuals trading in Istanbul stock exchange (BIST). The importance of this study stems from the scarcity of local studies focusing on behavioral finance within the scope of stock market investment. Accordingly, it is expected that the study will enrich this awareness in the field. Therefore, the effects of nonrational cognitive elements such as loss aversion, expectation, certainty, herding effect, intuitive factors, and anchoring on individuals' investment decisions were investigated in the study. As a result, the findings obtained from the research provide useful information to investors trading in BIST to adopt scientific foundations within the scope of behavioral finance in stock investments.

  Examining the relationship between self-compassion and mental toughness in athletes

  İpekoğlu, Gökhan; Şenel, Ebru; Karakuş, Kaan

  The aim of this study is to examine the relationship between mental toughness and self-compassion levels in athletes. The study included a total of 315 athletes, 148 women and 167 men, selected using a random sampling method. In the study, the Sport Mental Toughness Questionnaire and Self-Compassion Scale-Athlete Version were used as data collection instruments. As statistical analyses, t-tests were used for pairwise comparisons, one-way analysis of variance (ANOVA) for multiple comparisons, the Tukey test for intergroup pairwise comparisons in the ANOVA test context, and Pearson correlation analysis was used for examination of the relationship between two scale scores. Upon examining the study results, statistically significant differences were found for the total mental toughness scores of participants based on gender, type of sport, level of sport, and years of participation in sports (p<0.05). However, no significant differences were found in mental toughness scores based on age (p>0.05). Additionally, no statistically significant differences were observed in selfcompassion scores based on gender, age, type of sport, level of sport, or years of participation in sports (p>0.05). Finally, a positive and moderate significant relationship was found between the total scores for the Sport Mental Toughness Questionnaire and the Self-Compassion Scale-Athlete Version (p<0.01). Based on these results, it is expected that an increase or decrease in self-compassion levels in athletes will be associated with an increase or KEYWORDS decrease in their mental toughness levels. Consequently, it is recommended that athletes engage in cognitive training in addition to physical training. This is anticipated to enhance both their mental toughness and selfcompassion levels.

  Akyol, Mehmet; Bakkaloğlu, Ayşen

  In this paper, the effects of agricultural value added, urbanisation and energy consumption on environmental quality in MINT (Mexico, Indonesia, Nigeria, Turkey) countries were analysed for the period between 1992-2019. In the first stage of the study the panel analysis was used then the existence of horizontal cross-section dependence between the variables was tested and then the CIPS test, was used to test the stationarity of the series. In the paper where the existence of homogeneity was tested with the Delta test, the long-run relationship between the series was tested with the Pedroni panel cointegration test. Finally, the effects of agricultural value added, urbanisation and energy consumption on the environment were analysed by fully modified least squares estimator (FMOLS) analysis. According to the FMOLS results, the increase in agricultural value added and urbanisation rate has a negative impact on environmental quality, while renewable energy consumption has a positive impact on environmental quality. The results of the study show that more environmentally friendly policies should be developed and implemented in the agricultural production process in the country group in question, renewable energy investments and consumption should be increased, and the urbanisation rate should be taken under control and environmentally friendly new generation city plans should be put into effect urgently.

  Yaşam doyumu ile çalışmaya tutkunluk arasındaki ilişkide psikolojik iyi oluşun aracılık rolü

  Benk, Osman; Kenek, Gökhan; Sımsek, Tugçe

  Bu çalışmanın amacı bireylerin sahip oldukları genel yaşam doyumlarının, psikolojik iyi olma durumlarına ve bir çalışan olarak işlerine olan tutkunluklarına etkisini ortaya koymaktır. Bununla birlikte psikolojik iyi oluşun, yaşam doyumu ile çalışmaya tutkunluk arasında öngörülen aracılık rolünün incelenmesi araştırmanın diğer bir amacıdır. Araştırma, Karadeniz Bölgesi’nde öğrenci barınma hizmetleri kapsamında öğrenci yurtlarında görev yapan çalışanlar örnekleminde 2022 yılı Haziran ile Temmuz ayları arasında gerçekleştirilmiştir. Veri toplamak için yüz yüze anket yönteminin kullanıldığı araştırmada 191 katılımcıdan geri dönüş sağlanmıştır. Elde edilen veriler SPSS26 paket programında korelasyon ve regresyon analizleri ile analiz edilmiştir. Toplanan veriler ve gerçekleştirilen analizler doğrultusunda elde edilen bulgulara göre tüm hipotezler kabul edilmiştir. Hipotezlerin kabulü ile birlikte; bireylerin yaşamlarına ilişkin sahip oldukları tatmin duygusunun onların psikolojik olarak kendilerini iyi hissetmelerinde ve iş hayatlarında da bunu sürdürerek, örgütsel etkinlik ve verimlilik için arzu edilen ve pozitif çalışan davranışlarından biri olarak kabul edilen çalışmaya tutkunluğun gelişmesinde önemli rol oynadığı ifade edilebilir. Sonuçlar yaşam doyumunun artması ile birlikte psikolojik iyi oluş ve çalışmaya tutkunluğun da artış göstereceğine işaret etmektedir. Aynı zamanda psikolojik iyi olma durumunun da çalışmaya tutkunluğun önemli bir belirleyicisi olduğu tespit edilmiştir.
