The role conflict of physical education and sport teachers in Turkey: Teaching or coaching? : Türkiye’de beden eğitimi ve spor öğretmeninin rol çatışması: Öğretmenlik mi? Antrenörlük mü?

Physical education (PE) teachers in Turkey fulfill the coaching role within school sports activities in addition to teaching roles. However, coaching and teaching are different professional fields. In this regard, it is estimated that PE teachers experience role conflicts in the current system. The present study aimed to evaluate the role conflict situation from different perspectives in accordance with the opinions of the PE teachers. Six PE teachers, three female and three males, voluntarily participated in the study. In order to examine the role conflict in depth and to explain this situation better, the research was designed as phenomenology in qualitative research method A semi-structured interview form prepared by the researchers was used as a data collection tool. In the analysis of the data obtained, content analysis method was used to make objective and systematic inferences. The study yielded the outcome that especially young PE teachers had a role conflict and that they were negatively affected by this situation. PE teachers with a high level of sportive background stated that they felt closer to the coaching role than the teaching role. Finally, all PE teachers who participated in the study emphasized that coach support was very important in this process. They also reported that they could not spare time for their families and relatives due to high training hours and that they experienced physical and mental fatigue.   Özet Türkiye’de beden eğitimi (BE) öğretmenleri öğretmenlik rollerinin yanında okul sporları faaliyetleri kapsamında antrenörlük rolünü de yerine getirmektedirler. Ancak antrenörlük ve öğretmenlik birbirinden farklı mesleki alanlardır. Bu kapsamda, BE öğretmenlerinin mevcut sistem içerisinde rol çatışması yaşadıkları öngörülmüştür. Bu araştırmada, rol çatışması durumunun Türkiye’deki BE öğretmenlerinin görüşleri doğrultusunda farklı açılardan değerlendirilmesi amaçlanmıştır. Araştırmaya üç kadın, üç erkek olmak üzere toplamda altı BE öğretmeni gönüllü olarak katılmıştır. Araştırma, rol çatışması durumunu derinlemesine incelemek ve bu durumu daha iyi açıklamak amacıyla nitel araştırma yönteminde fenomenoloji deseninde tasarlanmıştır. Veri toplama aracı olarak araştırmacılar tarafından hazırlanmış yarı yapılandırılmış görüşme formu kullanılmıştır. Elde edilen verilerin analizinde, objektif ve sistematik çıkarımlar yapmak amacıyla içerik analizi yöntemi kullanılmıştır. Araştırma sonucunda, özellikle genç BE öğretmenlerinin bu durumdan olumsuz etkilendikleri ve rol çatışması yaşadıkları sonucuna ulaşılmıştır. Üst düzey sportif geçmişe sahip BE öğretmenleri öğretmenlik rolüne kıyasla antrenörlük rolüne kendilerini daha yakın hissettiklerini belirtmişlerdir. Son olarak, araştırmaya katılan tüm BE öğretmenleri yüksek antrenman saatleri sebebiyle aile ve yakınlarına vakit ayıramadıkları, fiziksel ve zihinsel anlamda yorgunluk yaşadıklarını ifade ederek, antrenör desteğinin bu süreçte oldukça önemli olduğunu vurgulamışlardır

The Effect of Foreign Direct And Portfolio Investments on Stock Market Returns in E7 Countries

As a result of financial liberalization boundaries between financial markets have been disappeared and capital movements have accelerated which leads to rise of financial flows from developed to developing countries. Foreign investments can be realized as foreign direct investments indicating the ownership of physical assets in another country or as portfolio investments in assets for the sake of maximum return at minimum risk. The aim of this paper is to investigate the effects of foreign direct and portfolio investments on stock returns in E7 countries (Brazil, China, Indonesia, India, Mexico, Russia, Turkey) for the time period from 2005 to 2016 using panel data analysis. Results indicate a significant and positive relation between foreign portfolio investments and stock market returns whereas a negative relation between foreign direct investment and stock market returns. It is concluded that foreign portfolio investments have very crucial effect in increasing the stock returns in E7 countries

A Deep Learning-Based Hybrid Approach to Detect Fastener Defects in Real-Time

A fastener is an important component used to fix the rail in railways. Defects in this component cause the rail and ballast to remain unstable. If the defective fasteners are not replaced in time, it is inevitable that the train will derail, and serious accidents will occur. Therefore, this component should be inspected periodically. Conventional image processing-based control systems are affected by noise and different lighting conditions in the real environment. In this study, it is aimed to determine the defects of fasteners with a deep learning-based hybrid approach. The YOLOv4-Tiny method is used for fastener detection and localization. This method gives accurate results, especially for the detection of small objects. After the fastener position is determined, a new lightweight convolutional neural network model is used for defect classification. The proposed convolutional neural network for classification has a small network structure because it uses depth-wise and pointwise convolution layers. When the experimental results are compared with other known transfer learning methods, better results were obtained in terms of training/test time and accuracy

Davranışsal finans ve anomaliler: Ocak ayı anomalisinin İmkb 'de test edilmesi

Etkin piyasa hipotezinin teorik ve ampirik olarak sınanması amacıyla hisse senedi getirilerinin dolayısıyla endeks getirilerinin davranışsal özellikleri araştırılmaktadır. Burada endeks getirilerinde belirli dönemlerde ortalamadan sapmalar diğer bir deyişle anomaliler görülebilmektedir. Bu durum etkin piyasa hipotezine aykırı bir durum teşkil etmektedir. Çünkü etkin bir piyasa da, hisse senetleri ile ilgili bütün bilgi ve haberlerin hisse senedi fiyatlarına tam olarak yansıdığı dolayısıyla yatırımcıların normalin üzerinde bir getiri elde etmelerinin söz konusu olmadığı belirtilmektedir. Etkin piyasalarda meydana gelen sapmalar anomali olarak adlandırılmakta ve bu sapmaları, fiyat anomalileri ve çalışma kapsamında dönemsellik arz eden ve zamana dayalı takvimsel anomalilerle açıklamak mümkündür. Ocak ayı anomalisi en sık rastlanılan takvimsel anomalilerden biridir. Ayrıca bu anomali, hisse senetlerinin Ocak aylarında diğer aylara göre sistematik olarak daha yüksek getiri sağlamalarını açıklamaya yarayan bir anomalidir. Çalışmada, 2001-2011 dönemindeki İMKB-30 ve İMKB-50 Endeks getirileri kullanılmıştır. Araştırmada esas alınan dönem itibariyle Ocak ayı anomalisinin var olup olmadığı güç oranı yöntemi kullanılarak ortaya çıkarılmaya çalışılmıştır. Yapılan analiz sonucunda incelenen dönem içerisinde Ocak ayı anomalisine rastlanılmış ve bu anomalinin sebepleri açıklanmaya çalışılmıştırThe behavioral feature of index returns and thus stock returns are investigated in order to theoretically and empirically test the efficient market hypothesis. In this context, average deviations, in other words anomalies can be seen at index returns at certain times. This situation constitutes a situation contrary to the efficient market hypothesis. Because it is stated that all information and news relating to stocks fully reflect to stock prices at an efficient market and it is not possible that investors get a return more than normal. The deviations occurred in efficient markets are called as anomaly, and such deviations can be explained by periodic and time-based calendar anomalies within scope of price anomalies and operation. January anomaly is one of the most common calendar anomalies. In this context, January anomaly is the anomaly used to explain that stocks systematically provide higher returns in January than other months. In this study, ISE-30 and ISE-50 Index returns during the period 2001-2011 have been examined. In this study, it is tried to reveal whether or not January anomaly exists for the time subject to study with use of power ratio method. In the result, January anomaly has been observed within specified time and reason of this anomaly has been tried to explain

A Work Readiness Scale for Allied Health Graduates

Purpose: The transition for allied health graduates from university to the workforce has been perceived to be difficult and overwhelming, leading to early attrition within healthcare professions. Work readiness is a crucial aspect of successful transition to the workforce, however, the elements of work readiness are not clearly defined. The purpose of this project was to refine the measurement of work-readiness in allied health graduates. Method: A 62-item Work Readiness Scale for Allied Health Professionals (WRS-AH), based on a work readiness scale for a generic population of graduates, was validated and refined using an exploratory factor analysis. Results: Participants were 245 Australian allied health professional graduates who completed the WRS-AH. An exploratory factor analysis supported a four-factor solution with domains (interpersonal capabilities, practical wisdom, personal attributes, and organisational acumen) similar to the original WRS. The final WRS-AH32 had 32 items, demonstrated good reliability, and explained 38% of the total variance. Using the WRS-AH32, on average, the Australian allied health graduates reported an overall work readiness score of 80% (SD 8) with scores highest for practical wisdom (Mean 90%, SD 8) and lowest for personal attributes (Mean 65%, SD 14). Conclusions: The WRS-AH32 confirms that work readiness is a multi-dimensional construct, reflecting that work within a dynamic, 21st century healthcare system requires more than just profession specific work competence. The WRS-AH may provide a more targeted approach to interventions to improve work readiness in future allied health professional graduates. Recommendations: The WRS-AH32 is a reliable scale to measure the perceived work readiness of allied health graduates as they transition from university to the workforce however ongoing validation is needed to establish construct validity

An analysis of obese student's attitudes towards physical educationObez öğrencilerin beden eğitimi dersine karşı tutumlarının incelenmesi

In this study, it is aimed to analyze attitudes of obese students in high school towards physical education according to some variables. 74 secondary education student, 45 of them are girls and 29 boys who studied at three different Anatolian High Schools in the city of Niğde in the 2016-2017 academic year, have been participated in this study. As data collection tool, Physical Education attitude scale for secondary education students developed by Güllü and Güçlü (2009) has been used and coefficient of consistence (Cronbach Alpha) is 0,94. SPSS 23.0 packaged software has been used for assesing the result. Kolmogorov – Smirnov Test have been done regarding whether the data showed normal distribution or not and Kurtosis and Skewness values have been studied. Independent Sample T Test has been used to test the mean difference significance belonging to two group independent variables in the study. One Way ANOVA Test has been used to test the mean differences significence when the number of groups is more than two. At the end of the study, all of the attitude scores belonging to variables have been found high and it has been established that obese high school students’ attitudes towards Physical Education show statictically significant difference, according to gender, in favor of boys (p<0,05). Accordingly, it has been determined that students’ cognitive attitudes acording to obesity level for Physical Education show difference in favor of second grade obese students (p<0,05) and no significent difference found in students’ affective and behavioural attitudes (p>0,05). It has been identified that high school students’ attitudes towards Physical Education show no statistically significant difference according to their calass level variable and time variable which they spent with their communication instruments (p>0,05) As a result, when considering obese students’ positive attitudes towards physical education and sports, in view of obtained findings, it is possible to say that physical education and sports may contribute to increase the participation of obese students and thus make them become healthy individuals.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetBu araştırmada, lise düzeyinde öğrenim gören obez öğrencilerin beden eğitimi dersine yönelik tutumlarının bazı değişkenlere göre incelenmesi amaçlanmıştır.

Araştırmanın sonunda, değişkenlere ait tutum puanlarının hepsi yüksek bulunmuş olup, liselerde öğrenim gören obez öğrencilerin beden eğitimi dersine yönelik tutumlarının cinsiyete göre istatistiksel olarak erkekler lehine anlamlı farklılık gösterdiği tespit edilmiştir (p<0.05). Benzer şekilde öğrencilerin beden eğitimi dersine yönelik obezite düzeyine göre bilişsel tutumlarının 2. sınıf obez öğrenciler lehine anlamlı farklılık gösterdiği belirlenmiş olup (p<0.05), duyuşsal ve davranışsal tutumlarında anlamlı farklılık bulunmamıştır (p>0.05). Öğrencilerin beden eğitimi dersine yönelik tutumlarının öğrenim gördükleri sınıf düzeyine  ve iletişim araçları ile geçirdileri süre değişkenine göre istatistiksel olarak anlamlı farklılık göstermediği belirlenmiştir (p>0.05). Sonuç olarak, obez öğrecilerin beden eğitimi ve spor derslerine karşı tutumlarının olumlu olduğu göz önünde bulundurulduğunda elde edilen bulguların beden eğitimi ve spor derslerinin obez öğrencilerin spora katılımının arttırılması ve dolayısıyla onların sağlıklı bireyler olmalarında önemli düzeyde katkısının olabileceğini söylemek mümkündü

The effect of combined hyperbaric oxygen and iloprost treatment on the prevention of spinal cord ischaemia-reperfusion injury: an experimental study

Bozok, Sahin/0000-0002-1256-5055; Durakoglugil, Emre/0000-0001-5268-4262WOS: 000325763500005PubMed: 23946499Hyperbaric oxygen (HBO) has been shown to be effective in preventing neurological injuries in animal models of ischaemia, whereas iloprost (IL) prevents ischaemia-related mitochondrial dysfunction and reduces infarction size after focal cerebral ischaemia in animal models. the aim of the present study was to investigate the effect of combined HBO and IL treatment on spinal cord ischaemia-reperfusion (IR) injury by neurological, histopathological and biochemical methods in an experimental study. Eighty New Zealand white male rabbits were randomly allocated into one of five study groups. the HBO group received a single session of HBO treatment and the IL group received an infusion of 25 ng/kg/min IL; the HBO + IL group received both HBO and IL and the control group received only 0.9% saline; the fifth group was the sham group. Levels of S100 beta protein, neuron-specific enolase (NSE) and nitric oxide (NO) were measured at onset, at the end of ischaemia period and at the 24th and 48th hour of reperfusion. Physical activity was assessed using Tarlov criteria 24, and the spinal cords of the sacrificed rabbits were evaluated histopathologically. Additionally, tissue malondialdehyde (MDA) and antioxidant enzyme activities [total superoxide dismutase (SOD); catalase (CAT) and glutathione peroxidase (GSH-Px) were assessed. Neurological scores in the HBO, IL and HBO + IL groups were statistically significantly better compared with the control group at the 24th (P = 0.001 for all) and 48th hour (P = 0.001 for all). Histopathological scores in the HBO, IL and HBO + IL groups were also significantly better compared with the control group (P = 0.003, 0.001 and 0.001, respectively). Whereas MDA, NSE, S100 beta protein and NO concentrations were significantly lower, CAT and GSH-PX levels were significantly higher in either sham or treatment groups compared with the control group. Since we demonstrated beneficial effects on spinal cord IR injury, we think that both HBO and IL, either alone or in combination, may be reasonable in the treatment of IR injury. Furthermore, there did not appear to be synergistic effects with combined treatment. More research is needed for practical application in humans, following thoracoabdominal aortic surgery
