Scaling of Ideal Teachers Characteristics with Pairwise Comparison Judgments According to Pre-service Teachers Opinions
In this study, scaling the characteristics that should be found in an ideal teacher according to the pre-service teachers by using the pairwise comparison method was aimed. Thirteen characteristics that an ideal teacher should have were given to 211 pre-service teachers in the working group, and these 13 properties were first asked to be considered as a whole, and then each property was asked to be compared to another property, one by one, to prefer one property to another. The research data were obtained from 211 pre-service teachers in fall semester of the 2015-2016 academic year. The data were scaled according to the pairwise comparison method. According to the findings obtained, when the characteristics were aligned from the most important characteristic that an ideal teacher should have according to the pre-service teachers to the most unimportant one, it was determined that; he/she should have an intellectual personality (U10) should have a sense of humor (U7), should be open to being criticized (U2), should be motivating (U1), should have a smiling expression (U5), should have a good usage of diction (U8), should be trustworthy (U3), should be creative (U6), should be a researcher (U9), should use teaching techniques well (U10), should give importance to the students (U4), should have good communication skills (U9), should keep the distance with the students (U12)
Öğretmen adaylarının akademik başarısını etkilediği düşünülen özelliklerin sıralama yargıları yöntemine dayalı ölçeklenmesi
In this study, it is aimed that the features affecting the academic success of teacher candidates who have been attending the Faculty of Education be scaled on the basis of rank-order judgement scaling technique. Separately, considering the genders, the types of education and the class levels of the teacher candidates, the order of importance of the factors affecting the academic success on the basis of rankorder judgements has also been specified. The study group comprised 584 teacher candidates who had been attending Pamukkale University, The Faculty of Education between 2013-2014. The most important feature that seems to have affected the academic success of the teacher candidates is the motivation level. On the other hand, the feature with the level of least significance that seems to have affected their success is the fact that these candidates underestimate the faculty they have been studying at. Whereas the most significant factor in both males and females is the motivation level according to the gender variable, the least significant factor is the underestimation of the faculty by the teacher candidates studying there. When the type of education studied by the teacher candidates are taken into consideration, the most significant feature affecting the academic success, according to the teacher candidates of normal type of education, is the motivation level, whereas the teacher candidates of the secondary type of education seem to consider their academic success to be affected by the feature of employment concern
Investigating the wording effect in scales based on the different dimension reduction techniques
Bu araştırmanın amacı, olumlu ve olumsuz madde sayısının dengeli olmadığı çok boyutlu bir ölçekten elde edilen verinin boyutluluğunun çok boyutlu madde tepki kuramı, DETECT ve faktör analizi yöntemlerine dayalı olarak incelenmesidir. Bu amaçla, araştırma kapsamında velilerin okula yönelik oluşturdukları algılarının ortaya çıkarılması amacıyla geliştirilmiş bir ölçek kullanılmıştır. Çalışma grubunda 1388 veli yer almıştır. Ölçeğin uygulanmasından elde edilen verinin boyutluluğu faktör analizi, çok boyutlu madde tepki kuramı ve DETECT analizine dayalı olarak incelenmiştir. Üç farklı boyutluluk analizine dayalı olarak verinin boyutluluğu incelendiğinde, tüm yöntemlerde ortak biçimde olumsuz maddelerin ayrı bir boyut oluşturduğu görülmüştür. Buna göre, olumsuz maddeler arasındaki ilişkilerin yalnızca ölçekle ölçülen özellikle açıklanamayacağı, olumsuz maddeler arasındaki ilişkiler üzerinde maddelerin ifade ediliş yönünün de etkili olduğu belirtilebilir. Bu araştırmanın bulguları, veri setinde her teknikte ortaya çıkan güçlü bir ifade etkisi olduğunu göstermiştir. Bu bulgulara dayalı olarak, araştırmacı ve uygulayıcılara olumlu ve olumsuz maddelerin birlikte kullanıldığı ölçeklerden elde edilen verinin boyutluluğunun incelenmesine ilişkin önerilerde bulunulmuştur.This study aims to examine the dimensionality of a dataset obtained from the application of a multidimensional scale which is not balanced in terms of the numbers of the positively and negatively worded items based on the item response theory, DETECT, and factor analysis. To this aim, a scale developed to measure parents' perceptions of their children's school was utilized. The study group consisted of 1,388 parents. The dimensionality of the dataset obtained from the scale was examined based on the item response theory, DETECT and factor analyses. The results of the three methods commonly revealed that the negatively worded items formed a separate cluster. Based on this finding, it can be stated that relations among the negatively worded items cannot only be explained by the intended trait with the scale, and the wording of the items also affect the relations among the negatively worded items. No matter what dimension reduction technique was used to analyze the data, the study results evidenced the existence of a strong wording effect in the data set. Based on the study results, some recommendations were given to researchers and practitioners regarding how to examine the dimensionality of a dataset obtained from a scale including both positively and negatively worded items

Thymic stromal lymphopoietin levels are increased in patients with celiac disease
Thymic stromal lymphopoietin (TSLP) is a cytokine produced by epithelial cells in the lungs, skin and intestinal mucosa, and is involved in several physiological and pathological processes. In this study, we evaluated serum TSLP levels in patients with celiac disease (CD). The prospective study was conducted at a gastroenterology outpatient clinic between March 2018 and August 2018. Eighty-nine participants aged between 18 and 75 years were classified into following groups: 22 patients with newly diagnosed CD; 20 patients with CD who were compliant with a gluten-free diet (GFD); 32 patients with CD who were not compliant with a GFD; and 15 healthy controls. Demographic characteristics, disease duration, and selected biochemical and hematologic parameters were recorded and compared between groups. Median serum TSLP levels were 1193.65 pg/mL (range: 480.1–1547.1) in newly diagnosed CD patients, 110.25 pg/mL (range: 60.3–216.7) in CD patients who were compliant with a GFD, 113.1 pg/mL (range: 76.3–303.4) in CD patients who were not compliant with a GFD, and 57 pg/mL (range: 49–67.8) in healthy controls. Overall, there was a significant difference in serum TSLP levels between groups (p = 0.001). Patients with newly diagnosed CD had the highest serum TSLP levels. There was no significant difference in serum TSLP levels between patients with CD who were or were not compliant with a GFD. TSLP appears to be involved in the pathogenesis of CD. Further studies are required to determine if the TSLP signaling pathway can be used in the treatment of CD
Decompressive hemicraniectomy in acute ischemic stroke
INTRODUCTION: Cerebral edema is the leading cause of mortality and morbidity in ischemic stroke patients. Decompressive hemicraniectomy may be beneficial to patients that fail to respond to medical treatment. In this study, clinical features and prognostic factors of patients that underwent decompressive hemicraniectomy due to acute ischemic stroke were evaluated.
METHODS: We examined 21 ischemic stroke patients who underwent decompressive hemicraniectomy. Demographic features and neuroimaging findings were recorded. Functional status of patients were evaluated with modified Rankin Scale. Clinical features and neuroimaging findings of the patients who died were compared with the survivors during hospitalization.
RESULTS: Twenty-one patiens were included in this study. Twelve of the patients were male, 9 were female. The mean age of these patiens was 58.7±8.2 (46 - 78). The main initial NIHSS score was 12.5±4.5. Territory of infarctions were supplied by middle cerebral arter in 17 patients, internal carotis arter in 4 patients. The mean time of decompressive hemicraniectomy was 2.9±2.5 days, hospitalization duration was 42.6±39.2 days. Five (% 23.8) patiens died in-hospital. There were no relation between clinical features, neuroimaging findings and mortality.
DISCUSSION AND CONCLUSION: Decompressive hemicraniectomy is a significant treatment option for ischemic stroke patients who deteriorate despite receiving medical treatment
