    (Universitatea Babes-Bolyai, 2016) Emhan A.; Tongur A.; Turkoglu I.
    Social capital and organizational commitment and performance have long been the subjects of many studies as these concepts drive organizational outputs. This study aims to investigate the relationships between these concepts. The study collected data using a questionnaire survey comprising 26 questions conducted with 308 officers working in the tax offices of the provinces of Diyarbakır, Batman and Mardin in Southeastern Turkey. A separate form was used to collect some demographic variables from the respondents. The findings indicate a positive and significant relationship between social capital and performance. This study also confirmed that organizational commitment has a mediating effect between social capital and performance. © 2016, Universitatea Babes-Bolyai. All rights reserved.

    (Taylor and Francis Ltd., 2017) Keser S.; Keser F.; Kaygili O.; Tekin S.; Turkoglu I.; Demir E.; Turkoglu S.
    It is known that Celtis species have been used in healing wound, epilepsy crisis, and stomach pain among the people. The antiradical (DPPH, OH, ABTS) activities, phytochemical compounds (total proanthocyanidin, total flavonoid, total phenolic, flavonoids, phenolic acids, sterols, lipid soluble vitamins, fatty acids), antimicrobial, antiproliferative (MCF-7, HCT-116, A2780, PC-3) activities of water, ethanol, methanol extracts of C. tournefortii fruits were evaluated in this study. All the C. tournefortii fruit water extracts were higher scavenged OH radical than standard antioxidant BHT. It was detected that C. tournefortii includes high amount of ?-tocopherol (2.65 mg/kg), vitamin D (10.05 mg/kg), ergosterol (78.70 mg/kg), stigmasterol (185.90 mg/kg), unsaturated fatty acids (74.47%). C. tournefortii extracts showed antiproliferative activity on MCF-7, HCT-116, A2780, PC-3 cancer cell lines and antimicrobial activity on some microorganisms when compared to standard antibiotics. Also, this study is the first report about phytochemical contents, antiproliferative, antimicrobial, antiradical properties of C. tournefortii fruits. © 2017 Har Krishan Bhalla & Sons.
