Teachers’ affective and physical well-being:emotional intelligence, emotional labour and implications for leadership

PurposeThis study aims to examine the role of teachers’ emotional intelligence (EI) and emotional labour (EL) strategies in their affective and physical well-being.Design/methodology/approachThe quantitative data were collected from 436 primary school teachers. Likert-type scales were used to measure the variables. Confirmatory factor analyses were performed for the construct validity of the scales, and path analysis was used to test the hypothesised model.FindingsThe final structural equation model suggests that teachers' EI levels and display of appropriate EL strategies significantly reduce their stress, anxiety, burnout and psychosomatic complaints (PSCs). The final model shows that the deep acting strategy, which includes more adaptive emotion regulation strategies, improves teachers’ affective and physical well-being, while the surface acting strategy has a detrimental effect on their well-being.Originality/valueTo the best of the authors’ knowledge, this study is the first in the literature to highlight the importance of school teachers’ EI and EL strategies in managing stress, anxiety, burnout (affective well-being),and alleviating PSCs (physical well-being) within a single structural equation model. The findings have implications for educational leaders in fostering teachers’ emotional competencies and resources

Plio-quaternary evolution of the Kucuk Menderes Graben southwestern Anatolia, Turkey

The Kucuk Menderes Graben (KMG) is part of the horst-graben system of southwestern Anatolia (Turkey), bounded by the Bozdag horst in the north and the Aydin horst in the south. The Plio-Quatemary evolution of the KMG has been evaluated using the nature of the Miocene-Quaternary fill sediments and palaeostress analysis of slip data measured in different parts of the graben

Teachers’ Moral Intelligence: A Scale Adaptation into Turkish and Preliminary Evidence

The purpose of this work is to adapt the existing Moral Competency Index (MCI) developed by Lennick and Kiel in a sample of teachers. The validated Turkish version of MCI is based on the item pool of the original MCI with a slight adaptation of the items to fit the context of teacher leadership. The translated form was administered to 773 teachers in Gaziantep city. Exploratory factor analysis, Cronbach’s Alpha and Split-half reliability, and item analysis were performed through SPSS, while the first and second order confirmatory factor analyses were performed through AMOS. Results showed that adapted Turkish form of MCI (Ogretmen Ahlaki Yeterlik Olcegi) is reliable and valid, and the four-dimensional original factorial structure (integrity, responsibility, forgiveness, and compassion) was confirmed and maintained. Finally, multiple regression analyses were performed. Results showed that female teachers have higher levels of moral competencies in the dimensions of integrity and forgiveness. Also, as teachers’ age increases, their general moral competency scores increase in the dimensions of integrity, responsibility, and compassion

Ultrasound imaging of the fetal optic nerve from a different plane

Objective In this study, we aimed to visualize the fetal optic nerve and its sheath in a lateral oblique plane by ultrasound. Methods This cross-sectional prospective study was conducted at 20–22 weeks of gestation on healthy pregnant women who applied to our perinatology clinic for anomaly screening. Optic nerve sheath diameter (ONSD) measurements were taken from the lateral orbital and the retroorbital planes twice by the same sonographer. Ultrasound durations were recorded. Intraobserver variability was calculated for both techniques. The Bland-Altman analysis was performed for the lateral orbital technique. Results A total of 45 pregnant women were evaluated in the study. The intraclass correlation coefficient value of the lateral orbital technique was 0.722 (p<0.001), suggesting that the ONSD was measured similarly by the same observer. The ONSD mean measured by the lateral orbital (LO) technique was higher than the ONSD mean measured by the retroorbital (RO) technique (2.10±0.13 vs 1.21±0.13 mm, p<0.001). The ONSD measurement with the LO technique was determined to be more time-effective than the RO technique (129.6±31.3 vs 228.2±32.7 sec, p<0.001). Conclusion It is demonstrated that by using the lateral orbital technique, the optic nerve and its sheath can be visualized separately without the shadowing artifact of the lens. This technique also takes less time than the RO technique. There is a need for more extensive research on this subject with magnetic resonance imaging (MRI) confirmation

Diagnostic Value of Dynamic Contrast-Enhanced Magnetic Resonance Imaging in the Evaluation of the Biliary Obstruction

Purpose. In this study, our purpose was to investigate the diagnostic efficacy of the dynamic contrast-enhanced magnetic resonance imaging (MRI) method in the patients with bile duct obstruction. Materials and Methods. 108 consecutive patients (53 men, 55 women, mean age; 55.77 ± 14.62, range 18–86 years) were included in this study. All the patients underwent conventional upper abdomen MRI using intravenous contrast material (Gd-DTPA) and MRCP in 1.5 Tesla MRI scanner. MRCP images were evaluated together with the T1 and T2w images, and both biliary ducts and surrounding tissues were examined for possible pathologies that may cause obstruction. Results. MRI/MRCP findings compared with final diagnoses, MRI/MRCP in the demonstration of bile duct obstruction sensitivity 96%, the specificity 100%, and accuracy 96.3%, in the detection of presence and level of obstruction, the sensitivity 96.7%, specificity 100%, and accuracy 97.2%, in the diagnosis of choledocholithiasis, the sensitivity 82.3%, specificity 96%, and accuracy 91.7%, and in the determination of the character of the stenosis, sensitivity 95.6%, specificity 91.3%, and accuracy 94.5% were found. Conclusion. The combination of dynamic contrast-enhanced MRI and MRCP techniques in patients with suspected biliary obstruction gives the detailed information about the presence of obstruction, location, and causes and is a highly specific and sensitive method

An investigation of the effect of placental growth factor on intrapartum fetal compromise prediction in terminduced high risk pregnancies

Objectives: To date, there is no available test to predict the risk of intrapartum fetal compromise (IFC) during labor, either starting spontaneously or induced due to obstetrics indications. The aim of this study was to examine the effectiveness of placental growth factor (PIGF) in identifying cases that develop intrapartum fetal compromise (IFC) in term high-risk pregnancies induced for labor.Material and methods: This prospective cross-sectional study was conducted on 40 IFC+ cases and 40 IFC- cases withhigh-risk term pregnancy and labor induction started in the Health Sciences University Gazi Yaşargil Training and Research Hospital, between January 2018 and April 2018. Comparisons were made between the groups in respect of placental growth factor (PIGF) levels, and obstetric and neonatal outcomes.Results: The PIGF level was found to be statistically significantly lower in the IFC+ cases compared to the IFC- cases. For a PIGF cutoff value of 32 pg/mL for the prediction of IFC+ cases, sensitivity was 74.4%, specificity 73.2%, NPV 75% and PPV 72.5%, with a statistically significant difference determined between the groups. The IFC+ development risk increased 7.91-fold in patients with PIGF ≤ 32 pg/mL.Conclusions: The PIGF levels in cases of IFC+ high risk pregnancies were found to be statistically significantly lower than those of IFC- cases. However, further, large-scale randomized controlled research is necessary to demonstrate this relationship better

The Effects of Different Diet Models on Oocyte Quality, Oocyte Maturation and in Vitro Fertilization Outcomes in Mice

Nutritional quality affects fertility in both men and women. Nutrition should be considered in the prevention and treatment of infertility in men and women. In this study, we evaluated IVF rates, oocyte maturation and oocyte quality in a female animal model feding ketogenic, western and standard type diet. Female BALB / c mice were allocated to three groups: (a) control; (b) Western and (c) Ketogenic. After feeding female mice with these 3 feeding groups for 4 weeks, IVF was administered before sacrification of the mice. The number of collected oocytes and oocyte quality, fertilization rates and embryo quality were evaluated.The number of total oocytes was the highest in the ketogenic diet and the least in the western diet. MII stage oocytes in the ketogenic group were statistically significantly higher than the control group and western groups. Fertilized oocyte count was significantly lower in the western group compared to the other two groups. When the two-cell zygote stage was evaluated, it was found that the results were better in the ketogenic diet group and worse in the western diet group. The worst results in terms of the number of zygotes reaching the blastocyst stage were observed in the western type nutrition group, and the best results were observed in the group on the keteogenic diet. The results of our study show that western nutritional models negatively affect IVF results, while ketogenic diet has a positive effect.

Modeliranje strukturnih jednadžbi na temelju veza između povjerenja nastavnika u menadžment, predanosti menadžmentu, zadovoljstva menadžmentom i namjere napuštanja organizacije

This study aims to determine the relationships among teachers’ trust in the manager, commitment to the manager, satisfaction with the manager and teachers’ intent to leave. The data was collected on the sample of 478 primary school teachers using self-report scales. Two alternative structural models were examined: one proposed that satisfaction with the manager causes commitment, while the other one proposed that commitment causes satisfaction. Both alternative models yielded exactly the same good fit indices. According to the first model, the teachers’ trust in manager predicts their satisfaction with manager and commitment to manager positively, while trust in manager negatively predicts their intent to leave through the mediating effect of satisfaction with manager. According to the second model, teachers’ trust in manager positively predicts their satisfaction with manager and commitment to manager, while trust in manager negatively predicts the teachers’ intent to leave through the mediating effects of commitment to manager and satisfaction with manager.Cilj ovoga istraživanja je odrediti veze između povjerenja zaposlenika u menadžera, predanosti menadžeru, zadovoljstva menadžerom i namjere nastavnika da napuste ustanovu u kojoj rade. Podaci su prikupljeni na uzorku od 478 nastavnika osnovne škole koji su upotrebljavali skale samoprocjene. Ispitana su i dva drugačija strukturna modela: jedan koji tvrdi da zadovoljstvo menadžmentom vodi predanosti i drugi koji tvrdi da predanost menadžmentu vodi zadovoljstvu. Oba modela pokazala su jednako dobre indekse pogodnosti. Prema prvome modelu povjerenje nastavnika u menadžera pozitivno utječe na njihovo zadovoljstvo menadžerom i predanost menadžeru, dok to isto povjerenje u menadžera umanjuje njihovu namjeru da napuste organizaciju, kroz medijacijski učinak zadovoljstva menadžerom. Prema drugome modelu, povjerenje nastavnika u menadžera pozitivno utječe na njihovo zadovoljstvo menadžerom i na predanost menadžeru, dok povjerenje u menadžera umanjuje njihovu namjeru da napuste organizaciju, kroz medijacijski učinak predanosti menadžeru i zadovoljstva menadžerom
