Economic liberalization and the antecedents of top management teams: evidence from Turkish 'big' business

There has been an increased interest in the last two decades in top management teams (TMTs) of business firms. Much of the research, however, has been US-based and concerned primarily with TMT effects on organizational outcomes. The present study aims to expand this literature by examining the antecedents of top team composition in the context of macro-level economic change in a late-industrializing country. The post-1980 trade and market reforms in Turkey provided the empirical setting. Drawing upon the literatures on TMT and chief executive characteristics together with punctuated equilibrium models of change and institutional theory, the article develops the argument that which firm-level factors affect which attributes of TMT formations varies across the early and late stages of economic liberalization. Results of the empirical investigation of 71 of the largest industrial firms in Turkey broadly supported the hypotheses derived from this premise. In the early stages of economic liberalization the average age and average organizational tenure of TMTs were related to the export orientation of firms, whereas in later stages, firm performance became a major predictor of these team attributes. Educational background characteristics of teams appeared to be under stronger institutional pressures, altering in different ways in the face of macro-level change

Identification of lactic acid bacteria isolated from Tarhana, a traditional Turkish fermented food

WOS: 000271051600004PubMed ID: 19703719Tarhana is a traditional fermented product produced from a mixture of spontaneously fermented yogurt and wheat flour in Turkey. The aims of the present study were to enumerate and identify for the first time by molecular biology-based methods predominant lactic acid bacteria (LAB) isolated during processing of Tarhana. Samples were collected from eight different regions of Turkey. In order to explore the relationship between raw material and the microbiology of Tarhana, yogurt and wheat flour were also analyzed. A total of 226 Gram-positive and catalase-negative isolates were obtained from MRS, M17 and SBM (Slanetz and Bartley Medium). The isolates were grouped and identified using a combination of pheno- and genotypic methods including rep-PCR fingerprinting [(GTG)(5) primer], multiplex PCR, 16S rRNA gene sequencing and carbohydrate assimilation profiling. Pediococcus acidilactici were found to constitute 27% of the isolates, 19% were identified as Streptococcus thermophilus, 19% as Lactobacillus fermentum, 12% as Enterococcus faecium, 7% as Pediococcus pentosaceus, 5% as Leuconostoc pseudomesenteroides, 4% as Weissella cibaria, 2% as Lactobacillus plantarum, 2% as Lactobacillus delbrueckii spp. bulgaricus, 2% as Leuconostoc citreum, 1% as Lactobacillus paraplantarum and 0.5% as Lactobacillus casei. The different production sites investigated all had individual LAB profiles, but with P. acidilactici and S. thermophilus being isolated from the majority of samples. The main source of A acidilactici and S. thermophilus was found to be the yogurt. (c) 2009 Elsevier B.V.

What is the protective effect of krill oil on rat ovary against ischemia-reperfusion injury?

Ozkan, Zehra Sema/0000-0001-9185-3663; EREL, Ozcan/0000-0002-2996-3236WOS: 000460180500012PubMed: 30484932Aim In this study, we aimed to investigate the protective effect of krill oil (KO) against ischemia-reperfusion (I/R) injury on rat ovary. Methods This study was conducted with 32 Wistar Albino rats. Rats were divided into four groups, with eight rats in each group-as follows: Sham group, I/R group, I/R + low dose KO group (50 mg) and I/R + high dose KO group (500 mg). The histopathological and follicle counts were performed on the right ovary. The total antioxidant status, total oxidant status and oxidative stress index were evaluated on the left ovary. And also serum N-thiol level, serum T-thiol level, serum disulfide (SDS) level, serum disulfide/N-thiol and serum disulfide/T-thiol ratios were evaluated too. Results A statistically significant difference was determined between the I/R group and all the other groups for all parameters. There was significant difference between KO groups and the Sham group for the parameters of serum N-thiol, serum T-thiol, SDS, serum disulfide/N-thiol and serum disulfide/T-thiol. SDS, total oxidant status and oxidative stress index were determined to be the highest in the I/R group and the lowest in the low dose KO group. The total antioxidant status values were found to be the highest in the high dose KO group and the lowest in the I/R group. Follicle counts and histological injury scores showed no significant difference between Sham and KO groups. Conclusion This study demonstrated that KO has beneficial effects on decreasing the injury after I/R on rat ovary.Krkkale University Scientific Research Commission [2018/003]This research was funded by Krkkale University Scientific Research Commission (Project number: 2018/003).
