On the validity and reliability studies of the scale, a content validity analysis was conducted to determine whether the items to be included in the scale were sufficient in terms of quality and quantity. The exploratory factor analysis used to test the construct validity of the scale reduced the draft scale's 47 items to 35 and resulted in a three-factor structure (Adaptation-Stability-Agility). It was seen that the first factor explained %29,197 of total variance, the second factor explained %21,291 of total variance, the third factor explained %19,288 of total variance and the rate of total variance explanation for this scale was %69,776. The scale's three-factor structure was later validated using confirmatory factor analysis. Cronbach's Alpha value of the confirmatory factor analysis is .974 for the first factor (Adaptation); .906 for the second (Stability); .945 for the third factor (Agility). As a result of the study, it was determined that the Organizational Resilience Scale is a valid and reliable measurement tool for primary and secondary public education schools.

To provide evidence-based data for health providers and promote postpartum screening, this systematic review and meta-analysis was conducted to access the risks of type 2 diabetes mellitus (T2DM) diagnosis after gestational diabetes mellitus (GDM) in different demographic and maternal subgroups. Methods MEDLINE, Embase and Cochrane Library were searched systematically. Unadjusted relative risks (RRs) and 95 per cent confidence intervals (CIs) were calculated and pooled using a random-effects model. Heterogeneity was assessed with Cochrane's Q text and by calculating I2 values. Subgroup analyses were conducted to address the disparities of type 2 diabetes conversion after gestational diabetes in different demographic and maternal subgroups. Results 1809 publications were screened and 39 cohort studies including 2,847,596 women were selected. In these studies, 78,893 women were diagnosed as T2DM at six weeks or later after delivery. The unadjusted RRs of women diagnosed T2DM at six weeks or later after delivery ranged from 1.32 (95% CI, 0.46-3.37) to 47.25 (95% CI, 2.95-758.01) with a pooled unadjusted RR of 8.92 (95% CI, 7.84-10.14). Older women, women with a family history of diabetes, Black and non-Hispanic White women and women living in Europe and South-East Asia had a higher risk of developing T2DM after GDM. Interpretation & conclusions It is suggested that healthcare providers may focus on older women with GDM and women with GDM and a family history of diabetes. Black and non-Hispanic White women with GDM may receive more attention, and healthcare providers, especially those in Europe and South-East Asia, may pay more attention to preventive measures for postpartum T2DM.

Arastirma verileri, bu calisma kapsaminda arastirmacilar tarafindan gelistirilen olcegin, Turkiye’nin kuzey-batisinda yer alan iki farkli devlet universitesinde 1. sinifta ogrenim gormekte olan 630 ogrenciye uygulanmasi ile elde edilmistir. Bu calismada nicel arastirma yontemlerinden betimsel tarama modeli kullanilmistir. Arastirmada kullanilan “Universite Tercihlerini Etkileyen Faktorler Olcegi”ne iliskin yapilan acimlayici faktor analizi sonuclarina gore olcegin alti alt-boyuttan olustugu ve toplam varyansin % 59.58’ini acikladigi belirlenmistir. Arastirma sonucunda, ogrencilerin universite tercihlerini etkileyen en onemli faktorlerin “gelecek kariyer beklentileri” ve “universitelerin egitim kalitesi ve populerligi” oldugu ortaya cikmistir.

It is the duty of teachers to manage these conflicts in a way that ensures the effectiveness of the school. Previous researches mostly focus on the identification of conflict management strategies experienced by elementary school principals. In this study, teachers who are party to the conflict are discussed. Thus, the reasons for conflicts experienced by elementary school teachers are important in that their use of conflict management strategies can be transformed into the 1 Bu çalışma birinci yazarın ikinci yazar danışmanlığında hazırladığı Yüksek Lisans Tezi'nden üretilmiştir. 18-22 Nisan 2018 tarihleri arasında Antalya'da düzenlenen 27.
