The effects of Euro/TL volatility on the performance of Turkey - European Union trade: empirical evidence

Bu çalışmada; 1996-2011 döneminde, Euro/TL kurundaki dalgalanmaların Türkiye-AB ticaretini nasıl etkilediği araştırılmıştır. Bu bağlamda, öncelikle Philips-Perron ve KPSS birim kök testleri ve daha sonra da, Zivot-Andrews ve Lee- Strazicich yapısal kırılma testleri gerçekleştirilmiştir. Son olarak ise, değişkenler arasındaki ilişkinin yönünü belirlemek amacıyla Dolado-Lütkepohl Granger nedensellik testi uygulanmış ve Türkiye-AB ticaretinde çift yönlü nedensellik tespit edilmiştir.In this study the effect of Euro/TL exchange rate fluctuations on Turkey-EU trade is analyzed for 1996-2011 period. In this context, the Philips-Perron and KPSS unit root tests are carried out first. In addition, the Zivot-Andrews and Lee-Strazicich structural break tests were also performed. Finally, Dolado-Lutkepohl Granger causality test was applied in order to determine the direction of the relationship between the variables. The tests revealed a bi-directional causality in Turkey-EU trade

Ekonomik büyüme ve borsa getirisi arasındaki ilişki: Türkiye örneği

Financial development is one of the most important determinants of the economic development. Financial developments in Turkey began in the early 1980s and still have continued. During this period, it has survived a severe interaction between financial development and economic growth. In this study, the causality relationship between stock returns and economic growth in Turkey it was analysed over the period 1998Q2-2014Q2. In this context; firstly, Bootstrapped Toda-Yamamoto and Frequency Domain causality tests were applied in order to understand the causality relationship between the two variables. As a result of the Bootstrapped Toda-Yamamoto causality test results, there is no relation of causality between the variables, but according to Frequency Domain causality test stock returns cause the economic growth in short term and economic growth cause stock returns in medium term.Finansal gelişme ekonomik kalkınmanın en önemli belirleyicilerinden birisidir. Türkiye’de finansal gelişme 1980’li yılların başında başlamış ve halen de devam etmektedir. Geçen süre içerisinde finansal gelişme ile ekonomik kalkınma arasında ciddi bir etkileşim yaşanagelmiştir. Bu çalışmada, Türkiye’de 1998Q2-2014Q2 döneminde borsa getirisi ve ekonomik büyüme arasındaki ilişki incelenmiştir. Bu bağlamda, iki değişken arasındaki nedensellik ilişkisini tespit etmek amacıyla Bootstrap tabanlı Toda-Yamamoto ve frekans dağılımı nedensellik testleri uygulanmıştır. Bootstrap tabanlı Toda-Yamamoto nedensellik testi sonuçlarına göre değişkenler arasında nedensellik ilişkisi bulunmamaktadır. Fakat, frekans dağılımı nedensellik testi göstermektedir ki; borsa getirisi kısa dönemde ekonomik büyümenin ve ekonomik büyüme de orta dönemde borsa getirisinin nedenidir

The relationship between attitude toward physical activity and weight gain in children and young adolescence

IntroductionThe purpose of this study was to investigate the association between attitudes toward physical activity and weight gain among children and young adolescents with an additional focus on the impact of gender on these attitudes.MethodsEmploying a descriptive survey method, data were systematically gathered via purposive sampling from 11 specific cities in Türkiye, ensuring representation from all seven regions. A total of 3,138 students, aged between 9 and 14 years, participated in this study, with a distribution of 46% girls and 54% boys. To assess the attitudes of children and young adolescents toward physical activity, the Youth Physical Activity Attitude Scale was utilized. Height and body weight measurements were taken to determine the body mass index of participants. SPSS 26.0 software facilitated the statistical analyses, including Pearson correlation analysis to explore relationships between variables. Multivariate Analysis of Variance was employed to evaluate the impact of age, BMI, and gender on attitudes toward physical activity.ResultsParticipants classified as normal weight exhibited a more positive attitude towards physical activity compared to their obese and overweight counterparts. Moreover, a significant gender difference emerged, with boys demonstrating significantly higher positive attitudes toward physical activity than girls. However, no significant difference was observed in negative attitudes based on gender. The study also revealed that an escalation in negative attitudes towards physical activity correlated with students being categorized as underweight, overweight, or obese, as opposed to having a normal weight status. Additionally, a statistically significant divergence in both positive and negative attitudes towards physical activity was found based on age. Specifically, the results indicated that students aged 9 and 14 exhibited lower levels of positive attitude when contrasted with their counterparts of different age groups. Conversely, in the domain of negative attitudes, students at the age of 9 scored higher than their peers in other age categories.DiscussionAttitudes towards physical activity can serve as a convenient indicator and guide for assessing the effectiveness of various practices or interventions aimed at promoting physical activity, with recognition of the significant gender difference in positive attitudes among children and young adolescents

Postresectional lung injury in thoracic surgery pre and intraoperative risk factors: a retrospective clinical study of a hundred forty-three cases

<p>Abstract</p> <p>Introduction</p> <p>Acute respiratory dysfunction syndrome (ARDS), defined as acute hypoxemia accompanied by radiographic pulmonary infiltrates without a clearly identifiable cause, is a major cause of morbidity and mortality after pulmonary resection. The aim of the study was to determine the pre and intraoperative factors associated with ARDS after pulmonary resection retrospectively.</p> <p>Methods</p> <p>Patients undergoing elective pulmonary resection at Adnan Menderes University Medical Faculty Thoracic Surgery Department from January 2005 to February 2010 were included in this retrospective study. The authors collected data on demographics, relevant co-morbidities, the American Society of Anesthesiologists (ASA) Physical Status classification score, pulmonary function tests, type of operation, duration of surgery and intraoperative fluid administration (fluid therapy and blood products). The primary outcome measure was postoperative ARDS, defined as the need for continuation of mechanical ventilation for greater than 48-hours postoperatively or the need for reinstitution of mechanical ventilation after extubation. Statistical analysis was performed with Fisher exact test for categorical variables and logistic regression analysis for continuous variables.</p> <p>Results</p> <p>Of one hundred forty-three pulmonary resection patients, 11 (7.5%) developed postoperative ARDS. Alcohol abuse (p = 0.01, OR = 39.6), ASA score (p = 0.001, OR: 1257.3), resection type (p = 0.032, OR = 28.6) and fresh frozen plasma (FFP)(p = 0.027, OR = 1.4) were the factors found to be statistically significant.</p> <p>Conclusion</p> <p>In the light of the current study, lung injury after lung resection has a high mortality. Preoperative and postoperative risk factor were significant predictors of postoperative lung injury.</p
