On Sabır and Agency

This article focuses on the pious practice of sab?r (patience) within the context of the weaving neighborhoods in Konya, Turkey. Through an ethnographic analysis of the everyday politics of the practice of sab?r, which is central to labor relations, this article adds to and complicates feminist analyses of labor politics and the economy by highlighting the interconnected nature of ethical religious practice and labor politics. Additionally, I argue for the need to go beyond the question of whether women have or lack agency as subjects in feminist analyses of labor politics and relationships, and instead point out the need for the empirical examination of specific, contextually-bound practical conditions through and within which women cultivate various forms of ethical action and subjectivities. In pointing out the importance of a project that analyzes operations of power with a keen awareness of context, this essay presents an ethnographically grounded discussion of pious practice within the context of Konya's weaving neighborhoods, underscoring the effects of the coexistence of exploitation and empowerment on the construction of women weavers’ selfhoods.     

Association between sarcopenia and erectile dysfunction in males with type II diabetes mellitus

Background: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED.

Methods: The study included 98 male patients with type II diabetes mellitus (DM) aged 18–80?years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5–10 points indicated severe ED, a score of 11–20 indicated moderate ED, and a score of 21–25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups.

Results: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59?±?11.46?years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p?Conclusions: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance.     

COVARIATE-ADJUSTED REGRESSION FOR LONGITUDINAL DATA INCORPORATING CORRELATION BETWEEN REPEATED MEASUREMENTS

We propose an estimation method that incorporates the correlation/covariance structure between repeated measurements in covariate-adjusted regression models for distorted longitudinal data. In this distorted data setting, neither the longitudinal response nor (possibly time-varying) predictors are directly observable. The unobserved response and predictors are assumed to be distorted/contaminated by unknown functions of a common observable confounder. The proposed estimation methodology adjusts for the distortion effects both in estimation of the covariance structure and in the regression parameters using generalized least squares. The finite-sample performance of the proposed estimators is studied numerically by means of simulations. The consistency and convergence rates of the proposed estimators are also established. The proposed method is illustrated with an application to data from a longitudinal study of cognitive and social development in children.     

Partial covariate adjusted regression

Covariate adjusted regression (CAR) is a recently proposed adjustment method for regression analysis where both the response and predictors are not directly observed [?entürk, D., Müller, H.G., 2005. Covariate adjusted regression. Biometrika 92, 75–89]. The available data have been distorted by unknown functions of an observable confounding covariate. CAR provides consistent estimators for the coefficients of the regression between the variables of interest, adjusted for the confounder. We develop a broader class of partial covariate adjusted regression (PCAR) models to accommodate both distorted and undistorted (adjusted/unadjusted) predictors. The PCAR model allows for unadjusted predictors, such as age, gender and demographic variables, which are common in the analysis of biomedical and epidemiological data. The available estimation and inference procedures for CAR are shown to be invalid for the proposed PCAR model. We propose new estimators and develop new inference tools for the more general PCAR setting. In particular, we establish the asymptotic normality of the proposed estimators and propose consistent estimators of their asymptotic variances. Finite sample properties of the proposed estimators are investigated using simulation studies and the method is also illustrated with a Pima Indians diabetes data set.     

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.     

Infants' identification of gender in biological motion displays

Infants' knowledge of social categories, including gender-typed characteristics, is a vital aspect of social cognitive development. In the current study, we examined 9- to 12-month-old infants' understanding of the categories “male” and “female” by testing for gender matching in voices or faces with biological motion depicted in point light displays (PLDs). Infants did not show voice–PLD gender matching spontaneously (Experiment 1) or after “training” with gender-matching voice–PLD pairs (Experiment 2). In Experiment 3, however, infants were trained with gender-matching face–PLD pairs and we found that patterns of visual attention to top regions of PLD stimuli during training predicted gender matching of female faces and PLDs. Prior to the end of the first postnatal year, therefore, infants may begin to identify gender in human walk motions, and perhaps form social categories from biological motion.     

Race and Redistricting: What the Print Media Conveys to the Public about the Role of Race

In a series of voting rights cases, the U.S. Supreme Court held that race-based redistricting, particularly the intentional formation of majority–minority districts (districts in which voters of color constitute a majority of eligible voters) may be unconstitutional if race was the predominant factor in the formation of the district. The Court stated that "redistricting legislation that is so bizarre on its face that it is unexplainable on grounds other than race" may violate the Constitution because of the messages such districts send to the public ( Shaw v. Reno , 1993 ). Yet neither the Court nor social scientists have examined whether the existence of race-conscious majority–minority districts sends messages to voters and what the nature of these messages may be. This research begins to address this scientific issue. In a quantitative content analysis, we examined messages about racial redistricting conveyed to citizens via the print media. Our sample consisted of 355 newspaper articles about redistricting included in the Lexis–Nexis database between 1990 and 2005. We found that newspaper coverage of racial districting contains messages to citizens about the motives involved in redistricting, the individuals and groups who are responsible for it, and its actual and expected effects. This finding is consistent with the Supreme Court's assumption that districts, particularly bizarrely shaped ones, convey distinct messages to voters. The specific messages communicated varied in important ways across the articles. Newspapers in states subject to Section 5 of the Voting Rights Act because of their history of discrimination against voters of color covered racial redistricting differently than states not subject to Section 5. We discuss the legal and theoretical implications of these findings for understanding the role of race in legislative redistricting efforts.     

Association of vitamin D status and the risk of cardiovascular disease as assessed by various cardiovascular risk scoring systems in patients with type 2 diabetes mellitus

Objective: The aim of the present study was to evaluate the relationship between vitamin D (25[OH]D) status and the risk of cardiovascular disease as assessed by various cardiovascular risk scoring systems such as QRISK2, BNF, ASSING, SCORE, and Framingham in patients with type 2 diabetes mellitus(T2DM).

Methods: The study included 108 patients with vitamin D insufficiency (25[OH]D?≥?10–30?ng/mL) and 100 patients with vitamin D deficiency (25[OH]D?Results: HbA1c levels were significantly higher in patients with vitamin D deficiency. Patients with vitamin D deficiency had significantly higher Framingham risk score (p?p?r?=?0.537) and a weak but statistically significant correlation between 25[OH]D levels and BNF score (r?=?0.295). 25[OH]D levels were significantly higher and HbA1c levels were significantly lower in patients with Framingham cardiovascular risk score ≤10%.

Conclusion: We found a close relationship with Framingham cardiovascular risk score in diabetic patients with very low serum vitamin D levels. Cardiovascular risk as assessed by the Framingham’s scale increases with decreasing 25[OH]D levels. BNF score was negatively correlated with 25[OH]D levels.     

Beliefs about Deliberation: Personal and Normative Dimensions

Democratic deliberative theory has long emphasized the importance of citizen deliberation as a form of political participation and a centrally important component of any vital democracy. Public deliberation and discourse among citizens has been less frequently investigated as a form of political participation than more standard indicators such as voting or volunteering for political organizations. This research examines the extent to which internalized beliefs about deliberation are associated with deliberation outcome measures among a national sample of high school students participating in a year-long deliberation forum, Project 540. Using a multilevel analysis, the research specifically tested the extent to which scales of personal and normative deliberation beliefs, independently and moderated by Project 540 participation, predict key deliberative outcomes (e.g., civic skills, intention to participate in civic affairs). We find that predeliberation endorsement of both personal and normative beliefs predicts increases in certain positive deliberative outcomes, and that these effects are not moderated by participation in Project 540. The implications of these findings for deliberative democracy theory and for developing effective citizen deliberation forums are discussed .     

The relationship between vitamin D level and erectile dysfunction in patients with type 2 diabetes mellitus

Recent studies have suggested that a relationship could exist between 25-hydroxyvitamin D [25(OH)D] deficiency and erectile dysfunction (ED). The present study evaluated the relationship between 25(OH)D levels and ED in male patients with type 2 diabetes mellitus (DM). The study included 98 patients with type 2?DM aged between 18–80 years. The International Index of Erectile Function (IIEF-5) Questionnaire was administered. The patients were divided into three groups according to IIEF-5 scoring: IIEF-5 score between 5–10, severe ED; IIEF-5 score between 11–20, moderate ED; IIEF-5 score between 21–25, no ED. Biochemical parameters, 25(OH)D and hormonal analysis tests were obtained in all patients. All parameters were compared between these three groups. Of 98 patients included in the study, 32 had severe ED, 45 had moderate ED and 21 had no ED. The mean age was 55.12?±?9.39 years and the mean 25(OH)D level was 13.69?±?8.15?ng/ml. When the three groups were compared, 25(OH)D levels were significantly lower in patients with the IIEF-5 score between 5–10 (p?=?0.020). There was a moderate positive relationship between IIEF-5 score and 25(OH)D level (r?=?0.21, p?=?0.038). The patients with severe ED have considerably lower 25(OH)D levels.
