An ethical problem in troubled times: Ethical decision making by local managers employing immigrant workforce in Gaziantep, Turkey

This paper aims to understand the ethical decision-making process of local managers of medium-sized companies in Gaziantep, a highly industrialized metropolis in Turkey, near the Syrian border, where there has been an influx of Syrian refugees. Intensive interviews were conducted using a semi-structured questionnaire allowing participants to state their views and tell their stories. The findings revealed that the managers of the companies had difficulty making ethical decisions about how to treat the Syrian immigrants, especially during the initial phase of the crisis, and they took wrong steps when they faced with both economic and social conflicts. Thus, they faced some serious ethical challenges.WOS:00057149930001

Sandviç yapı, Al/SiC fonksiyonel kademelendirilmiş kompozit yüzey plakaları ve Al 3003-H19 alaşımı bal peteğinden oluşmaktadır. Sandviç yapının darbe cevabı, fonksiyonel kademelendirilmiş destek plakalarının farklı malzeme kompozisyonu, vurucu kütlesinin sabit olduğu farklı çarpma enerjileri ve bal peteği çekirdek malzemesinin farklı hücre duvar kalınlıkları için incelenmiştir.Sandwich structures are specific applications of the composite materials whose high performance properties are obtained by different material combinations. They have quite extensive usage areas (aeronautics and aerospace, automotive, defense, etc.) with their several high quality properties compared with the conventional materials. Sandwich structures can be consisted of different facesheets and core materials in order to have required properties for the application areas. The determination of the low-velocity impact response of the sandwich structures has an important role by reason of their working areas with impulsive loadings. The deformations and energy absorption capability of the honeycomb sandwich structures reinforced by the functionally graded plates under low-velocity impact loads were investigated using explicit finite element software, LS-DYNA®. The sandwich structure was consisted of Al/SiC FG facesheets and Al 3003-H19 aluminum honeycomb core. The impact response of the sandwich structure was investigated in terms of different material compositions of the FG plates, impact energies and cell wall thickness of the honeycomb core

Investigation of factors predicting job satisfaction of school counsellors in Turkey

Job satisfaction can be defined as individuals' perceptions of satisfaction towards their profession. This concept is also considered to be important for the school counselling profession because school counsellors’ high level of job satisfaction is assumed to have positive effects not only on them but also on their students and accordingly on the education system. Therefore, it is thought that it is important to examine the factors that predict job satisfaction of school counsellors. For this purpose, this study was conducted on 194 (female=145 and male=49) school counsellors in Turkey. As a result of the research, it was determined that there was a significant positive relationship between school counsellors’ job satisfaction and professional self-esteem. In addition, job satisfaction of school counsellors working in the private sector was found to be higher than those working in the public sector. It was found that job satisfaction of school counsellors did not differ significantly according to gender, age and school level variables

Effects of the phosphodiesterase type-5 inhibitor tadalafil on nociception, morphine analgesia and tolerance in rats

Aim: Tadalafil is a potent, selective and reversible inhibitor of phosphodiesterase type 5 (PDE5) enzyme breakdowning cyclic guanosine monophosphate (cGMP). In this study, we aimed to investigate the effects of tadalafil on nociception, morphine analgesia and tolerance. Methods: In this study, 54 Wistar Albino (230-250 g) male rats were used. First of all, four different doses (2, 4, 8, 16 mg/kg) were used to determine the optimum effective dose of tadalafil on nociception. Optimum activity was found at 8 mg/kg and animals were divided into six groups: Saline (S), 8mg/kg tadalafil, 5mg/kg morphine (M), M+ tadalafil, morphine tolerance (MT) and MT+ tadalafil. Saline was given to the control group, tadalafil intraperitoneally and morphine subcutaneously administered at the indicated doses. To develop tolerance to morphine, 10mg/kg morphine was injected daily in the morning and evening for five days and tolerance was evaluated with single dose of morphine on sixth days. The resulting analgesic effect was measured with hot plate and tail flick analgesia tests and recorded at 30th, 60th, 90th and 120th minutes. Results: Tadalafil showed anti-nociceptive effect when given alone at different doses (p<0.05). However, tadalafil significantly decreased the analgesic effect of morphine (p<0.05). In addition, tadalafil significantly increased the tolerance to morphine (p<0.05). Conclusions: The phosphodiesterase type 5 inhibitor tadalafil have anti-nociceptive properties and it decreases analgesic effect of morphine, in addition improves tolerance development. These effects probably may occur via NO/cGMP pathway. &nbsp

Investigation of Architect and Non-Architect Participants’ Perceptual Evaluations on Different Period Mosque Facades

In architecture, perception based studies about building facades have become more popular. In recent studies, mostly residential buildings and business center type of buildings had been selected as target buildings. The lack of study of the perception of the facades of religious structures has created the basic motivation for this work. In the current study, the facade features of (Seljuk period, Ottoman period and Republic period) some important mosques from different periods were evaluated according to the adjective pairs of complexity, preference and impressiveness variables. Also, whether or not the general views of the mosques represent Islamic religion and their level of arousing curiosity were questioned. For this purpose, in the study, a total of 16 mosques were used. The results obtained from the participants as architect and non-architect are given. It is seen that the participant architects show a statistically more negative approach compared to those who are non-architects in the perceptual evaluations of the facades of the mosques for complexity variable. On the other hand, there was no statistically significant difference between the participants' evaluations of preference and impressiveness variables (at p <0.05 level)
