Evaluation of the relationship between microalbuminuria and 25-(OH) vitamin D levels in patients with type 2 diabetes mellitus

Background: 25-(OH) vitamin D (VD) deficiency has been described as potential risk factor for the development of diabetes in many epidemiological studies. 25-(OH) VD deficiency and insulin resistance associated with this deficiency are common findings in patients with type 2 diabetes mellitus. The objective of this study is to evaluate the relationship between 25-(OH) VD levels and microalbuminuria.

Methods: The patients with type 2 diabetes mellitus aged between 40 and 65 years, who were admitted to the diabetes outpatient clinics of our hospital, were evaluated in two different groups. The first group consisted of 119 patients with insufficient 25-(OH) VD levels (10–30?ng/mL) and the second group consisted of 121 patients with 25-(OH) VD deficiency (≤10?ng/mL). The relationship between 25-(OH) VD levels and the level of microalbuminuria was evaluated in the two groups.

Results: The mean 25-(OH) VD level was 11.5?ng/mL and the mean HbA1c level was 9.1%. When the patient groups were evaluated according to 25-(OH) VD levels, HbA1c values were significantly higher in patients with a 25-(OH) VD level of 10?ng/mL or lower (p?=?.039). 25-(OH) VD levels were not significantly different between patients with different stages of renal failure (p?=?.119), whereas the level of microalbuminuria was significantly different (p?=?.030).

Conclusions: This study found that the level of microalbuminuria was significantly higher in patients with 25-(OH) vitamin D deficiency compared to patients with 25-(OH) VD insufficiency.

Evaluation of Early Adolescent Subjective Well-Being in Terms of Submissive Behavior and Self-Esteem

This research aimed to investigate the correlation between subjective well-being and submissive behavior and self-esteem in students in the early adolescent period. The research was completed with a relational design. The research group comprised sixth, seventh, and eighth class middle school students in the spring term of the 2015–2016 academic year in Trabzon province. Data collection tools included a Personal Information Form, Submissive Behavior Scale, Two-Dimensional Self-Respect Scale (Self-Liking and Self-Confidence Scale), Satisfaction with Life Scale and Positive and Negative Affect Schedule. The results of the correlation analysis found a significant positive correlation between subjective well-being and self-esteem (r?=?0.54, p?<?0.01; 95% CI [0.44, 0.61], Cohen’s d?=?1.28); however, the correlation between subjective well-being and submissive behavior was not significant (r?=?–0.02, p?>?0.05; 95% CI [–0.11, 0.09], Cohen’s d?=?0.04). There was a significant negative correlation identified between self-esteem and submissive behavior (r?=?–0.10, p < 0.05; 95% CI [–0.20, –0.01], Cohen’s d?=?–0.20). Additionally, according to our findings, self-esteem accounts for 29% of the variation in well-being (F(1, 367)?=?150.79, p?<?0.001). The contribution of self-esteem to the subjective well-being explanatory model was found to be significant (sz?=?0.54, p?<?0.001).     

The Spatial Context of Social Integration

Social integration is the harmonious and coherent processing of the structures of a social system and refers to the degree to which people are integrated to the systems of a social structure. Although social integration issue is often considered on a regional scale and especially in association with the migration literature, it is also associated with urban dynamics. Especially in metropolitan cities, it is a process that shapes the opportunities and resources of urban life, such as socio-cultural life, the built environment and urban services. This paper aims to analyze the spatial differentiation of the interactive dimension of social integration in the case of Istanbul. It describes different forms and levels of social relations of the residents of Istanbul while also depicting the interaction between social integration and location, particularly in terms of residential area characteristics. With this aim, different types of social relations are analyzed using statistical and spatial analysis methods. The results of the study indicate that different social groups which are integrated into the macro structures of the society with different degrees produce different forms of social relations and they also live in residential areas which differ with their environmental quality.     

Examining Mediator Role of the Social Safeness on the Relationship Between Vengeance and Life Satisfaction

The aim of the present study is to examine the mediating role of social safeness on the relationship between vengeance and life satisfaction. Participants were 305 university students who completed a questionnaire package which includes the Vengeance Scale, the Social Safeness and Pleasure Scale, and the Life Satisfaction Scale. According to the results, social safeness and life satisfaction were predicted negatively by vengeance. On the other hand, life satisfaction was predicted positively by social safeness. In addition, social safeness mediated the relationship between vengeance and life satisfaction. Together, the findings illuminate the social processes underlying the association of vengeance with life satisfaction.     

A DESIGNER'S CHOICE BETWEEN SINGLE‐PRIZE AND PARALLEL TOURNAMENTS

In this article, I theoretically and experimentally compare a designer's profits from two tournament designs. The first design is a standard winner‐take‐all tournament with a single prize. The second design features two winner‐take‐all (parallel) tournaments with different prizes where individuals choose which tournament to enter before competing. I develop a simple model that illustrates how the relative performances of these designs change as contestants' abilities differ. The theoretical model shows that the designer's profit is higher (lower) in the parallel tournament when contestants' abilities differ greatly (are similar). I complement these findings with experimental evidence. The experiments show that the parallel tournament is more profitable under high heterogeneity, whereas under low heterogeneity, the designer is better off with the single‐prize tournament. Furthermore, high‐ability agents under‐participate and low‐ability agents over‐participate in the high‐prize tournament relative to the theoretical prediction. (JEL C72, D82, J33, M51, M52)     

Development of Infant Pointing from 10 to 12 months: The Role of Relevant Caregiver Responsiveness

Infants’ pointing frequency is a predictor of their later language abilities. Yet, predictors of pointing frequency in the first year of life are not well understood. Study 1 explored what factors in infants and caregivers at 10 months would predict the pointing frequency of infants at 12 months (N = 35). Infant‐driven predictors were infants’ fine‐motor skills and point‐following abilities. Caregiver‐mediated predictors were caregivers’ pointing frequency and responsiveness toward infants’ pointing. Relevant caregiver responsiveness at 10 months predicted infants’ pointing frequency at 12 months, controlling for the other factors and infants’ prior pointing frequency. Study 2 explored whether child‐level factors influence caregivers’ responsiveness (N = 49). We examined the hand shape of infants’ pointing (whole‐hand versus index‐finger) and the presence of point‐accompanying vocalizations. Infants’ vocalization‐accompanied points were more likely to elicit relevant responses from caregivers, while hand shapes played a less pronounced role. Together, the findings reveal an early emerging mutual relationship between infant pointing and caregiver behavior such that certain characteristics of infant pointing predict caregivers’ responsiveness, and relevant responsiveness toward infants’ pointing predicts the increase in infants’ pointing frequencies.     

Determining Six Sigma success factors in Turkey by using structural equation modeling

Since it includes strong statistical and executive techniques, Six Sigma (SS) succeeded in many countries and different sectors. Especially successful SS applications of many international companies have increased the interest of other companies. As a result of this, the number of implemented SS projects in various countries has increased. Although successful SS projects are often in mind, the number of failed projects because of various reasons is not as low as to be ignored. As well as there are many factors that affect the success level of SS projects, and these factors vary according to countries. In this study, a survey was applied to 117 people who have 1 of SS belts in order to determine success levels of the SS projects in Turkey. By using explanatory factor analysis and structural equation modeling, critical success factors were determined. According to the results, project selection and its scope, quality culture and defining and measuring of metrics were determined as the top factors that are affecting success levels of SS projects applied in Turkey. The results of the study were also compared with the results of similar projects implemented in other countries.

The maximum cardinality cut problem in co-bipartite chain graphs

A co-bipartite chain graph is a co-bipartite graph in which the neighborhoods of the vertices in each clique can be linearly ordered with respect to inclusion. It is known that the maximum cardinality cut problem (\({\textsc {MaxCut}}\)) is \({\textsc {NP}}{\text {-hard}}\) in co-bipartite graphs (Bodlaender and Jansen, Nordic J Comput 7(2000):14–31, 2000). We consider \({\textsc {MaxCut}}\) in co-bipartite chain graphs. We first consider the twin-free case and present an explicit solution. We then show that \({\textsc {MaxCut}}\) is polynomial time solvable in this graph class.
