The analysis of the relationship among perceived electronic service quality, total service quality and total satisfaction in Banking sector

In order to competitive and survive, businesses have to understand customers’ wants and desires. Today, banks are the cornerstone of finance sector and electronic banking services are becoming increasingly important in all areas. In accordance with this importance, banks should give much attention to enhance efficiency of these services. Service quality can be measured with the help of the servperf, servqual and e-s-qual scales. The aim of the current study is to investigate the structural relationships among electronic service quality, total service quality and total satisfaction by testing a structural model. The current study utilized a survey design. The data was collected from 223 participants in Turkey using a structured questionnaire which was derived from literature. Since there was no list available, convenient sampling method was used. The data at hand was analysed using the structural equation modelling (SEM), specifically Lisrel version 8.7. When the results are investigated, it can be said that the model is statistically significant. The goodness of fit indices of the revised model indicate adequate fit. All of the hypotheses except H1 and H3 were verified. A high level positive correlation was identified between the perception of total service quality and the perception of total satisfaction. The variables responsiveness, ease of use, product portfolio and security, which are the dimensions of e-service quality, affect total service quality perception and total satisfaction perception in parallel with the literature. Responsiveness and security are the dimensions which have the highest effect on e-service quality perception. Also total service quality perception affects highly total satisfaction perception

Investigation of The Effect of Pre-Service Classroom Teachers’ Critical Thinking Disposition on Their Media Literacy

It is important to develop a critical perspective in terms of interpreting the messages to be given to the individuals through media and questioning the authenticity and content of these messages. It is therefore necessary to train the individuals called media literate who can critically perceive and evaluate the information conveyed through the media to increase the positive effects of the media and to reduce their negative effects as much as possible. The purpose of the current study is to investigate the effect of the pre-service teachers’ critical thinking disposition on their media literacy. The study employed the relational survey model, one of the quantitative research methods. In order to collect data, a personal information form, the Critical Thinking Disposition Scale, and the Media Literacy Level Determination Scale were used as the data collection tools. As a result of the study, the critical thinking disposition of the pre-service teachers was found to be medium and their media literacy was found to be high. The critical thinking disposition was found to be varying significantly depending on their gender and grade level; their media literacy was found to be varying depending on grade level but not on gender. There is a positive but low relationship between critical thinking disposition and media literacy and critical thinking is a significant predictor of media literacy

Predictors of adverse perinatal outcomes in intrahepatic cholestasis of pregnancy

Objectives: Our objective was to evaluate in our clinic the perinatal outcomes of patients diagnosed with ICP based on pre-treatment maternal serum bile acid levels, attempt to identify the risk group and review the literature in light of this information.  Material and methods: In total, 370 patients diagnosed with ICP were included in the study, divided into two groups based on the fasting total serum bile acid level before UDCA (Group 1: 10 ≥ 40 μmol/L, and Group 2: ≥ 40 μmol/L). The groups were examined for clinical characteristics and pregnancy outcomes.  Results: It was found that preterm delivery and neonatal intensive care need increased at a serum bile acid cut-off value of 34 μmol/L. Regardless of serum bile acid, significantly higher rates of meconium-stained amniotic fluid and foetal distress were observed in patients whose diagnoses were made before 34 weeks of gestation.  Conclusions: Foetal complications over 40 μmol/L of serum bile acid were significantly increased. However, slightly lower levels cut-off values (34 μmol/L) were obtained in terms of preterm birth and neonatal intensive care need. The incidence of meconium-stained amniotic fluid and foetal distress was higher in patients whose diagnosis were made before 34 weeks of gestation.
