The effects of tightness-looseness in organizational culture on corporate entrepreneurship and firm performance: A regional study in Turkey

In this study, the tightness-looseness dimension, suggested as a cultural dimension of community was examined at organizational level. Introducing the tightness-looseness dimension to the literature, and identifying the effects of the dimension on corporate entrepreneurship activities and firm performance, which poses great importance for organizations, were the main purposes of the study. In the study, the correlations between dependent and independent variables were examined through the hypotheses suggested, and the consistency level of the model was analyzed through the structural equation modeling. It was concluded from the study that there was a significant positive correlation between the tightness-looseness level and corporate entrepreneurship and firm performance. Coefficients of corporate entrepreneurship, proactivity, innovational orientation, and coefficients of firm performance, and coefficients concerning the profit, growth, and customer satisfaction seem to be statistically significant. Accordingly, the higher (or lower) the level of looseness is, the higher (or lower) the level of corporate entrepreneurship and firm performance will be. The validity of the model on the target sample has been discussed considering the compliance indices of the model proposed in the study on Turkey's leading industrial enterprises. As the results of the analysis of the constructed structural equation model gave the values of good and acceptance level goodness of fit (RMSEA <0.05, GFI and CFI> 0.95 and AGFI> 0.90), the model was found to be acceptable

Assessing Postgraduate Students’ Satisfaction with Quality of Services at a Turkish University Using Alternate Ordered Response Models

The aim of this study is to determine postgraduate students’ general satisfaction with the quality of academic services. For this purpose, a written-questionnaire was conducted to 400 graduate students at Atatürk University, Turkey. The dependent variable of the study was the satisfaction level of graduate students which has a natural order. Hence, four different ordered logit models were performed to determine factors that may influence satisfaction levels of graduate students with the quality of academic services. Along with standard ordered logit model, other alternative ordered response models were also performed including generalized ordered logit model, partial constrained generalized ordered logit model, and heterogeneous choice model. Results reveal that a variety of factors are associated with quality of higher education services including age group, tuition fee, undergraduate education, monthly individual income, monthly household income, type of graduate school, current status of postgraduate education, advisor’s academic degree, and time elapsed for postgraduate education. The outcome of this study may give a valuable information for decision-makers of higher education institutions and may provide a benchmarking option in terms of past, present and future higher education policies

THE EFFECT OF DIODE LASER AS AN ADJUNCT TO PERIODONTAL TREATMENT ON CLINICAL PERIODONTAL PARAMETERS AND HALITOSIS: A RANDOMIZED CONTROLLED CLINICAL TRIAL

Aim: The aim of this study is to examine the clinical efficiency of diode laser periodontal pocket irradiation as an adjunct to conventional scaling and root planning (SRP) on periodontal parameters and halitosis. Material and Methods: In our randomized, controlled clinical trial, 40 patients with untreated chronic periodontitis were randomly separated into two group to receive SRP with laser (laser group n=20) or SRP solely (control group n=20). Plaque index (PI), gingival index (GI), probing pocket depth (PD), clinic attachment loss (CAL), bleeding on probing (BOP) and halitosis were recorded at baseline and 1st ,3rd and6th months after treatment by a periodontist. Results: Both treatment methods showed significant reductions in clinical parameters and halitosis levels compared to baseline. Conclusion: The present study indicates that compared to SRP solely, adjunctive applications of a 940-nm diode laser with SRP showed lower bleeding on probing and halitosis levels

CLINICAL ANALYSIS OF DESQUAMATIVE GINGIVITIS RELATED ORAL MUCOCUTANEOUS DISEASES

Objectives: Several mucocutaneous diseases are responsible for desquamative gingivitis (DG) and diagnostic delays are common in these diseases due to non-specific clinical oral presentations. The present study aimed to analyze the clinical features of DG-related mucocutaneous diseases with oral manifestations and compare the findings with previous reports. Materials and Methods: Thirty newly diagnosed patients with oral mucocutaneous disease in the Dermatology and Venereology Department of Akdeniz University Medical School, between January 2018 and January 2020, and referred to the Periodontology Department for periodontal treatment were evaluated retrospectively. Patients demographic data (age and gender), medical comorbidities, primary lesion site (oral or skin), and clinical features of gingival and oral lesions (location and symptoms) were examined. Results: There were 18 oral lichen planus (OLP), 8 pemphigus vulgaris (PV), and 4 mucous membrane pemphigoid (MMP) patients with oral involvements. The mean age of the patients was 50.03 ± 9.71 years with a female predominance (male to female ratio 1:1.7). All patients suffered from chronic burning sensation and oral pain. DG was detected in all three mucocutaneous diseases but OLP was the main disease associated with DG (60%). However other oral mucosal lesions and extraoral involvements were more frequent in PV patients. Conclusions: According to these results, OLP, MMP, and PV are the mucocutaneous diseases responsible for DG, and OLP is the most common cause of DG. Clinicans should be familiar with the clinical presentations and signs (patient complaints) of DG-related mucocutaneous disease for early diagnosis, proper treatment, and quality of life of the patient

Relationship between Hba1c and blood glucose level in hemodialysis patients with diabetes mellitus

Within in the scope of this study, a researchwas aimed at the relationship between HbA1c markersand blood glucose levels with DM, chronic renal failureand receiving dialysis treatment.Methods: In this study, monthly glucose levels and quarterlyHbA1c markers of 131 patients (53 female, 78 male)receiving dialysis treatment in a private dialysis centerbetween January 1, 2009-July 31, 2010 were evaluatedretrospectively.Results: The average age of 131 cases was 63.3±11.2years (range, 30-91). Gender distribution of the cases: 53female (40.5%), 78 male (59.5%). While the age averageof the females was 62.2±11.2 and the males’ was64.1±11.2. The average glucose level of the females andmales have a correlation to average HbA1c (Female:p<0.001, r=0.761, Males: p<0.001, r=0.743). The averageglucose level of the both case groups have a correlationto average HbA1c (p<0.001, r=0.755). While 32.8%of the examined HbA1c results were observed underthe level 6,5%, and 67.2% of the examined results wereobserved above the level 6.5%. While 18.3% of the preprandialblood glucose levels were obtained under 126mg/dl level, and 81.3% of the results were obtained above126 mg/dl level. It has been observed that the mean bloodglucose level has a correlation to average HbA1c level.Conclusion: The measurement of HbA1c and blood glucose(pre-prandial and postprandial) and the correlationbetween them, by virtue of the fact that, are vitally importantin cardiovascular mortality and morbidity, monitorof DM for the dialysis patients with diabetic nephropathy.Key words: Hemodialysis, diabetes mellitus, HbA1
