The relationship between organizational transparency and employee engagement

Bu araştırmanın temel amacı, örgütsel şeffaflığın çalışan tutkunluğuna katkısını incelemektir. Bağımsız değişken olan örgütsel şeffaflık kavramının bağımlı değişken olan çalışan tutkunluğu kavramı üzerinde açıklayıcılığa sahip olduğu öngörülmüştür. Akademik çalışmaların bazılarında, iç iletişim, açık iletişim ve çalışmaya tutkunluk kavramları arasındaki ilişkiler incelenmiştir. Ancak, örgütsel şeffaflık ve Saks (2006) tarafından tanımlanan ve literature kazandırılan çalışan tutkunluğu kavramı arasındaki ilişki Türk kültüründe henüz çalışılmamıştır. Bu noktada, araştırmamız özgün bir nitelik taşımaktadır ve örgütsel davranış yazınına önemli bir katkı sağlayacağı düşünülmektedir. Araştırmamızın örneklem grubunu yenilenebilir enerji, otomotiv, ilaç ve eğitim sektöründen çalışanlar oluşturmaktadır. 197 kişiye uyguladığımız araştırma ölçeklerinin analizleri için istatistik programı kullanılmıştır. Uygulanan regresyon analizi sonucunda, örgütsel şeffaflık kavramının çalışan tutkunluğunun iki alt kavramı olan örgüte ve çalışmaya tutkunluk üzerinde anlamlı bir katkısının olduğu bulunmuştur. -------------------- The main purpose of our study is to investigate the relationship between organizational transparency and employee engagement. We predict that the independent variable “organizational transparency” has a significant contribution on the dependent variable “employee engagement”. In academic literature, a number of researches investigated the relationship between internal communication, open communication and work engagement. However, the relationship between organizational transparency and employee engagement which was defined and developed by Saks (2006) has not been investigated in Turkish culture. At this point, our research has its own originality and will provide a significant contribution to organizational behavior area. The participants in the current study, are employees from renewable energy, automotive, pharmaceuticals and education sectors. Measurements were answered by 197 participants and statistical package program is used to test hypotheses and research questions. According to the results obtained through regression analyses, organizational transparency has a significant contribution on both of employee engagement concepts

Dark fermentative hydrogen production from sucrose and molasses

There are many factors affecting the dark fermentative hydrogen production. The interaction of these factors, that is, their combined effects, should be investigated for better design of the systems with stable and higher hydrogen yields. This study aimed to investigate the combined effects of initial substrate, pH, and biomass (or initial substrate to biomass) values on hydrogen production from sucrose and sugar-beet molasses. Therefore, optimum initial chemical oxygen demand (COD), pH, and volatile suspended solids (VSS) or initial substrate to biomass (VSS) ratio (S/X-o) values leading to the highest dark fermentative hydrogen production were investigated in batch reactors. An experimental design approach (response surface methodology) was used. Results revealed that when sucrose was the substrate, maximum hydrogen production yield (HY) of 2.3 mol H-2/mol sucroseadded was obtained at initial pH of 7 and COD of 10 g/L. Initial S/Xo values studied (4-20 g COD/g VSS) had no effect on HY, while the initial pH was found as the parameter mostly affecting both HY and hydrogen production rate (HPR). When substrate was molasses, initial COD concentration was the only variable affecting HY and HPR. Maximum of both was achieved at 10 g/L initial COD. Initial VSS values studied (2.5-7.5 g/L) had no effect on HPR and HY. This study also indicated that molasses leads to homoacetogenesis for potentially containing intrinsic microorganism and/or natural constituents; thus, sucrose is more advantageous for hydrogen production via fermentation. Homoacetogenesis should be prevented for effective optimization via response surface methodology, if substrate is a natural carbon source potential to have intrinsic microorganisms.

A Preterm Birth Caused By Postoperative Peritonitis and Peritoneal Abscess

Appendicitis is the most common condition leading to an intraabdominal operation for a non obstetric problem in pregnancy and diagnosis of appendicitis is complicated by the physiologic and anatomic changes that occur during pregnancy. Although a surgical procedure carries the risk of fetal loss or preterm delivery, delay in diagnosis also increases the risk of complications in both mother and fetus. The following case illustrates our experience and to analyze clinical characteristic and the pregnancy outcome of appendicitis during the third trimester of pregnancy.

Evaluation of structural valve deterioration and bioprosthetic valve failure utilizing the new European consensus definition in patients undergoing TAVI with first-generation devices: Outcomes beyond 5 years from a single center in Turkey

Objective: The long-term durability of transcatheter aortic bioprosthetic valves continues to be a major concern. Standardized criteria of the structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) have recently been defined. Limited studies have evaluated the longterm durability of transcatheter aortic valve implantation (TAVI) according to these new definitions. We aim to analyze the durability of TAVI beyond 5 years and to report the frequency of SVD and BVF
