Social Sources of Failure in Education: The Case in East and Southeast Turkey

The efficiency of education in East and Southeast Turkey (E&SE) has long been a subject of debate. Both regions are similar to each other and different from the other regions in terms of economy, culture, ethnic origin, and languages spoken. Sahin (1997) studied the efficiency of education in the E&SE and proposed that illiteracy is significantly the highest in both regions, the female student population is significantly lower, and students are significantly less successful in nationwide general proficiency examinations (OSS and OYS) compared to all the other regions. Social sources of failure were studied in terms of the distinguishing characteristics of both regions, from both practical and theoretical standpoints. The findings indicated inequality of educational opportunity rooted in geographical, economical, social (cultural, linguistic), and political factors.     

Strategic Intersectionality and Political Representation: Female Muslim Councilors in London

This article addresses questions of how race/ethnicity, gender, and religion influence political representation. We use original interview data to test a strategic intersectionality theory developed by Fraga and colleagues (2005) in the case of female Muslim councilors in London, the United Kingdom. The original strategic intersectionality theory proposes that women are more effective advocates for ethnic group interests due to their unique capacity to leverage three primary resources: a substantive policy focus, multiple identity advantage, and gender inclusive advantage. We modify the thesis by analyzing religion as an additional identity marker and further disaggregating the three primary sources of leverage. We use the modified thesis to test whether female Muslim councilors of three London boroughs are more effective advocates for Muslim interests than their non-Muslim colleagues. We find mixed evidence for the presence of the three sources of leverage associated with strategic intersectionality, resulting in a more complex theorizing of this phenomenon than that found in prior research. This study offers a new contribution to the operationalization of intersectionality and the literature on intersectionality and political representation.     

Economic Production Lot Sizing with Periodic Costs and Overtime*

Traditional approaches for modeling economic production lot‐sizing problems assume that a single, fixed equipment setup cost is incurred each time a product is run, regardless of the quantity manufactured. This permits multiple days of production from one production setup. In this paper, we extend the model to consider additional fixed charges, such as cleanup or inspection costs, that are associated with each time period's production. This manufacturing cost structure is common in the food, chemical, and pharmaceutical industries, where process equipment must be sanitized between item changeovers and at the end of each day's production. We propose two mathematical problem formulations and optimization algorithms. The models' unique features include regular time production constraints, a fixed charge for each time period's production, and the availability of overtime production capacity. Experimental results indicate the conditions under which our algorithms' performance is superior to traditional approaches. We also test the procedures on a set of lot‐sizing problems facing a national food processor and document their potential economic benefit.     

Flow Coordination and Information Sharing in Supply Chains: Review,Implications, and Directions for Future Research

Advances in information technology, particularly in the e‐business arena, are enabling firms to rethink their supply chain strategies and explore new avenues for inter‐organizational cooperation. However, an incomplete understanding of the value of information sharing and physical flow coordination hinder these efforts. This research attempts to help fill these gaps by surveying prior research in the area, categorized in terms of information sharing and flow coordination. We conclude by highlighting gaps in the current body of knowledge and identifying promising areas for future research.     

A new generalization of skew-T distribution with volatility models

In this paper, we propose a new generalized alpha-skew-T (GAST) distribution for generalized autoregressive conditional heteroskedasticity (GARCH) models in modelling daily Value-at-Risk (VaR). Some mathematical properties of the proposed distribution are derived including density function, moments and stochastic representation. The maximum likelihood estimation method is discussed to estimate parameters via a simulation study. Then, the real data application on S&P-500 index is performed to investigate the performance of GARCH models specified under GAST innovation distribution with respect to normal, Student's-t and Skew-T models in terms of the VaR accuracy. Backtesting methodology is used to compare the out-of-sample performance of the VaR models. The results show that GARCH models with GAST innovation distribution outperforms among others and generates the most conservative VaR forecasts for all confidence levels and for both long and short positions.     

Assessing a minimum pension guarantee for the voluntary IPS in Turkey

The returns from individual account pension plans are subject to fluctuations in capital markets. This increases income uncertainty for the beneficiary and exposes individuals to the risk of fluctuations in the economy in general and the stock market in particular. A minimum pension guarantee is a way to avoid this pitfall by providing a minimum annuity regardless of the actual investment performance of individual accounts. In this article, we present a cost analysis of a minimum benefit guarantee mechanism for the voluntary Individual Pension System in Turkey. We examine the cost estimates and the probability of providing guaranteed payments under various economic and demographic assumptions.     

Compassion fatigue in marriage and family therapy: implications for therapists and clients

Given that marriage and family therapists are exposed to a wide range of circumstances that leave them uniquely vulnerable to experiencing compassion fatigue, it is important to examine the stresses and hazards they face and what those consequences mean for both themselves and clients. It is essential that they identify how compassion fatigue negatively affects the therapeutic relationship and overall treatment outcome as well as that of the personal life of the family therapist. The marriage and family therapist is responsible and ethically obligated to identify and implement ways in which he or she can prevent and remedy compassion fatigue.     

Conceptualization of power sharing between partners in couple relationships: a scale development study in Turkey

In this study, the Power Sharing in Couple Relationships Scale (PSCRS) was developed to measure the distribution of power as experienced by individuals in heterosexual marriages or cohabiting relationships. Three sets of participants partook in the study: 27 individuals were in the pilot group; 400 individuals (female = 200, male = 200) were in the exploratory factor analysis group and 242 persons (female = 139, male = 103) were in the confirmatory factor analysis group. Factor analyses resulted in a structure consisting of 30 items and five dimensions, namely, friendship, power over, reactivity to relational stress, openness to influence, and making a relational claim. Results showed evidence for satisfactory psychometric properties.     

Association Between Unemployment Duration and Depression in the SouthWest Region of Turkey: A Cross-Sectional Study

ABSTRACT

Unemployment has risen as an effect of globalization in the country of Turkey. To date, no studies have examined the association between the duration of unemployment and perceived mental health. Therefore, the aim of this study is to evaluate the association between the duration of unemployment and the incidenence of depression among citizens in the southwest region of Turkey. A questionnaire was developed and distributed to 908 unemployed individuals. The questionnaire gathered sociodemographic characteristics and employment-related circumstances. To measure mental health, a depression inventory was administered and group-wise t-tests and logistic regressions were conducted. The findings show that long-term unemployed persons had more episodes of depressive moods in the past 12 months when compared with the group of the short-term unemployed. In addition, depression levels were higher among the long-term unemployed compared with the short-term unemployed. It was estimated that the duration of unemployment and the measurement of depression had a positive correlation. Risk factors that increased depression in the short-term unemployed were gender (female), older age, and greater periods of unemployment. However, higher education, income, and having social insurance significantly decreased the risk of developing depression for both the short-term and the long-term unemployed. Future recommendations include supportive counseling to increase motivation levels and developing strategies to handle periods of unemployment.     

A framework for production rescheduling in sociotechnical manufacturing environments

No plan survives contact with reality. Despite the rich research base regarding handling uncertainty in production planning and control systems, there is an intellectual gap between theory and practice with regard to handling unforeseen events generated by internal and external factors, such as unforeseen machine downtimes and changes in demand. Motivated by longitudinal observations in two industrial settings and an analysis of the relevant literature, a framework for rescheduling decision-making in the face of unforeseen production events is proposed. In practical settings, the effectiveness of decisions depends on a set of situational factors. The findings of this research can be utilised further to provide guidelines for developing effective decision support principles and systems, addressing the needs of organisational decision-makers.
