The development of critical reflection skills: An application of school and teacher themed movies

The present research aims to determine the effect of films including school and teacher whose learning processes are applied with “Critical Reflection Skills (CRS)” on the critical reflection skills of 4th primary education teachers. In accordance with this purpose, the research was carried out with 73 participants who were the 4th grade students in the Primary Education Teacher Training Department of Gazi Faculty of Education in Gazi University in 2012-2013 education year. The qualitative and quantitative research methods were applied together during the process. Data were collected with “The Critical Reflection Self-assessment Scale (CRSS)” - “Critical Team Application Focus Team Interview Form (CTAFTIF)” and “ Meta Team Observation Form”. During the data collection process, the participants watched the school and teacher containing films at first and then, “Critical Reflection Application (CRA)” adapted from “Critical Reflection Strategy with Teams” was applied. Content analysis was adopted in the analysis of the qualitative data gathered during the research process. In the analysis of the quantitative data, t-test and one-way variance analysis were used.  The results of the conducted research demonstrated that teachers started to generate thinking of critical reflection with school and teacher containing films and the CRA process. It was noticed that statistically a significant difference occurred between the control and experimental groups in terms of critical reflection skills

Evaluation of patients with fibrotic interstitial lung disease: Preliminary results from the Turk-UIP study

OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF. MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERSARS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board. RESULTS: A total of 336 patients (253 men, 83 women, age 65.8 +/- 9.0 years) were evaluated. Of the patients with sufficient data for diag-nosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPE None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPE Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively). CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and EANA positivity reduce the likelihood of IPF

The genetic history of the Southern Arc: a bridge between West Asia and Europe

By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe

Sperma Saklanmasında Düşük Yoğunluklu Lipoproteinlerin Rolü

The discovery that egg yolk has a beneficial effect on fertility in semen extenders led to its widespread use in semen extenders. Egg yolk is commonly found in semen extenders to preserve mammalian spermatozoa against cold shock during freeze-thaw process. Protective action of yolk is largely presumed to be due to low density lipoproteins (LDL). In recent years, there have been increasing demands to replace whole yolk in semen extenders because of presence of substances in yolk that inhibit respiration of spermatozoa or diminish their motility. Consequently, it could be of great benefit to remove these detrimental substances in yolk rather than complete egg yolk. Recent studies have confirmed that LDL extracted from egg yolk is successful for cryopreservation of semen from various species. Density gradient ultracentrifugation has been generally used for purification of egg yolk LDL. LDL are composed of 84-89% lipids and 11-17% proteins. Lipids of LDL are composed of approximately 69% triglycerides, 26% phospholipids and 5% cholesterol. Phospholipids play an essential role in the stability of LDL structure because association forces are essentially hydrophobic. LDL presents a density of 0.982 g/ml. They are spherical molecules of 17¬60 nm diameters. The interactions of lipid and protein are disrupted and under freezing, but interactions between proteins are increased and adhere to cell membranes, thus preserving spermatozoa membranes. In conclusion, researches are still carried out needed to evaluate and understand the respective roles of lipids and apoproteins from LDL and to isolate the antagonistic agent contained in egg yolk.Fertilite üzerine olumlu etkisinin keşfinden sonra yumurta sarısı, sperma sulandırıcılarında yaygın olarak kullanılmaktadır. Yumurta sarısının kullanılmasındaki temel amaç; dondurma çözdürme sonrasındaki soğuk şokuna karşı spermatozoanın korunmasıdır. Bu koruyucu etkisini, içerdiği düşük yoğunluklu lipoproteinler (LDL) ile gerçekleştirdiği düşünülmektedir. Son yıllarda yumurta sarısının tamamının kullanılması yerine, spermatozoon motilitesini olumsuz etkileyen içeriğinin uzaklaştırılarak, faydalı kısımlarının sulandırıcıya ilave edilmesi tercih edilmeye başlanmıştır. Çeşitli çalışmalarda yumurta sarısından elde edilen düşük yoğunluklu lipoproteinlerin farklı türlere ait spermaların dondurularak saklanmasında başarıyla kullanıldığı bildirilmektedir. Yumurta sarısından LDL elde etmek için genellikle ultrafaz santrifüj ile yoğunluk farkına göre ayırma yöntemi kullanılır. LDL, %84-89 lipid, %11-17 oranında proteinlerden oluşmaktadır. Lipid içeriğin yaklaşık olarak %69’unu trigliseridler, %26’sını fosfolipidler ve %5’ini de kolesterol oluşturmaktadır. Fosfolipidler özellikle hidrofobik karakterleri ile LDL yapısının korunmasında etkilidirler. LDL 0,982 g/ml yoğunluğa sahip bir moleküldür. 17-60 nm çapında olan ve küresel biçime sahip bu moleküllerin, dondurma sırasında spermatozoon membranına bağlanarak ve seminal plazma proteinleri ile birleşerek koruyucu etkilerini gösterdikleri düşünülmesine rağmen koruma mekanizması henüz tam olarak aydınlatılamamıştır. Çeşitli çalışmalarda bildirildiği üzere; sulandırıcılarda standart olarak kullanılan %20 yumurta sarısı yerine %8 LDL kullanımı, sperma parametrelerine olumlu katkı sağlamakta ve antioksidan enzim aktivitesini önemli ölçüde arttırmaktadır. Buna karşın sulandırıcıda %10’un üzerindeki oranlarda kullanılan LDL ise spermatozoa kalitesini azaltmaktadır. Sonuç olarak hem LDL yapısındaki lipid ve apoproteinlerin etki mekanizmalarının aydınlatılmasına yönelik hem de yumurta sarısındaki zararlı bileşenlerin izole edilmesine yönelik araştırmalar halen devam etmektedir

Turistik destinasyon açısından Konya ilinin marka kişiliği üzerine bir araştırma

Marka kişiliği (brand personality) kişilik özelliklerinin, markalarla özdeşleştirilmesi ile ortaya çıkan bir süreçtir. Tüketicilerin belirli bir markaya bağlılık göstermelerinde marka kişiliği önem taşımaktadır, çünkü marka kişiliği satınalma kararlarını etkilemekte ve rakipler arasından seçim yapmayı sağlamaktadır. Dolayısıyla pazarlamacılar ve işletmeler bu yaklaşımı göz önüne alarak markaları hangi kişilik özelliklerinin tüketiciler gözünde geçerlik kazandığını belirlemekte ve pazarlama iletişiminde bu özellikleri ön plana çıkarmaktadırlar. Destinasyon imajı; genel imaj, destinasyon markası, ve marka kişiliği modelinde incelendiğinde; turist öz-imajı ile ilişkilendirilmiştir. Bu bağlantı kişilerin hayat tarzları ve değerler sistematiğinin bir destinasyonu seçim sürecinde kilit derecede önemli olduğunu göstermektedir. Turistin destinasyon imajı hakkındaki düşüncesi ile kendi öz-kavramı ne kadar çok uyuşursa o destinasyona ziyaretle sonuçlanacak bir davranış eğilimi gözükecektir. Bu çalışma marka ve pazarlama dünyasına tüketici maddelerinden daha çok seyahat destinasyonları açısından bakmaya çalışmıştır. Hem yerli hem de yabancı turistler nezdinde turistik destinasyon olarak Konya ilinin marka kişiliği boyutları Aaker'in (1997) ölçeğinde uygulanmış, farklılaşmaları araştırılmış, destinasyon imajı ile turist öz-imajı ilişkilendirilmiş ve araştırma sonuçlarına dayanılarak ilin destinasyonun pazarlaması hakkında ipuçları elde edilmiştir.Brand personality is a process emerging as a result of identification of personality properties with brands. Brand personality takes importance for consumers to exhibit loyalty towards a certain brand since brand personality affects decisions of purchasing and enable to make a choice between competitors. Therefore, considering this approach, marketers and enterprises determine which personality properties become valid for consumers and bring these properties into the forefront in the communication. Destination image is associated with tourist self-image when examining in the model of general image, destination brand and brand personality. This relationship shows that life styles of individuals and their systematics of values are of vital importance during process of choosing a destination. How much opinion of the tourist regarding destination image is in accord with his/her self concept, tendency of behavior, which shall result in visiting that destination, shall be exhibited. This study addresses brand and marketing world in terms of travelling destinations rather than items of consumers. Dimensions of brand personality of Province of Konya, which is a touristic destination for both domestic and foreign tourists, were executed in accordance with Aaker's (1997) scale, its differentiations are investigated, the destination image is associated with tourist self-image, and based on results of the study, clues about destination marketing of the province are obtained

Determinants of private investments in Turkey: Examining the role of democracy

This study investigates the determinants of private sector investments in Turkey with a focus on democracy. Using the Autoregressive Distributed Lag (ARDL) bounds testing approach and two different democracy indices along with the other determinants of private investment, we estimated a private investment function for the 1975-2014 period. Our main finding is that democracy has a profound positive impact on private investment. Moreover, the results show that: (i) public investment is a substitute to private investment; (ii) macroeconomic instability dissuades private investment; (iii) real interest is a serious impediment to private investment; (iv) financial development and GDP growth rate stimulate private investment
