Abstract
Purpose
This study aims to evaluate the obesity and cardiometabolic disease risks of incarcerated men and to determine the related factors.
Design/methodology/approach
This study was cross-sectional and 139 incarcerated men were included. Data were collected using a questionnaire containing the Descriptive Information Form and the Pittsburgh Sleep Quality Index. The incarcerated men’ body mass index (BMI), waist circumference, waist-to-hip ratio and waist-to-height ratio were evaluated. The significance level of statistical tests was accepted as p < 0.05.
Findings
According to BMI, the rates of incarcerated men with overweight were 53.2% and with obesity were 13.7%. Their cardiometabolic disease risk according to waist circumference, waist-to-hip ratio and waist-to-height ratio was 47.5%, 53.2% and 73.4%, respectively. The cardiometabolic disease risk was 2.66 times higher in the married and 3.71 times higher in those with senior high school or lower education according to waist circumference, and 4.16 times higher in those who were in the aged = 40 years according to the waist-to-hip ratio, 3.49 times higher in those who were in the aged = 40 years and 4.26 times higher in those with senior high school or lower education according to the waist-to-height ratio.
Originality/value
To the best of the authors’ knowledge, this study is the first study in which obesity and the risk of cardiometabolic disease in incarcerated men was investigated in Türkiye. In the incarcerated individuals, there was an association between the increased cardiometabolic diseases risk and variables such as older age, being married and having senior high school or lower education.

This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.
Abstract
Purpose
This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.
Design/methodology/approach
This cross-sectional study was conducted with 562 45–64-year-old postmenopausal women who presented to a Family Health Center. To collect the data, the Descriptive Information Form and Food Frequency Questionnaire were used. In the data analysis, numbers, percentages, mean, standard deviation and multiple linear regression analysis were used.
Findings
The multiple linear regression analysis demonstrated that dietary putrescine intake was negatively associated with systolic blood pressure (ß = −0.179, p < 0.001), dietary spermidine intake was positively associated with waist circumference (WC) (ß = 0.142, p = 0.013), systolic blood pressure (ß = 0.188, p = 0.001), diastolic blood pressure (ß = 0.218, p < 0.001), body mass index (BMI) (ß = 0.169, p = 0.003) and waist-to-height ratio (WHtR) (ß = 0.156, p = 0.006), and dietary spermine intake was negatively associated with WC (ß = −0.158, p = 0.003), systolic blood pressure (ß = −0.195, p < 0.001), BMI (ß = −0.107, p = 0.042) and WHtR (ß = −0.138, p = 0.009).
Research limitations/implications
Owing to the study’s cross-sectional nature, the lack of succession in the cause–effect relationship, the use of self-report Food Frequency Questionnaire to determine dietary polyamine intake and the inability to analyze seasonal differences are among the limitations of the study.
Originality/value
In this study, an association was determined between dietary polyamines, metabolic risk parameters and anthropometric measurements. The findings suggest that dietary polyamines in human health should be further investigated owing to the increasing metabolic risk parameters.

Abstract
Purpose
The 12th sustainable development goal, responsible consumption and production, includes increasing awareness of circular economy practices. In this context, the authors base their study on remanufactured electronic products, a circular economy practice. The current research aims to examine the relationships between collectivistic values, reasons for purchasing remanufactured products (RPs) (product knowledge, perceived benefits, perceived awareness), reasons against purchasing RPs (perceived risk), attitude toward RPs and the intention to purchase RPs.
Design/methodology/approach
The authors conducted quantitative research on 259 consumers in an emerging market-Turkey. The authors benefited from structural equation modeling for data analysis.
Findings
This study shows that perceived awareness, attitude and product knowledge affect purchase intention. Perceived benefits, perceived risk, perceived awareness and product knowledge predict attitude. Collectivistic values affect product knowledge. Furthermore, attitude acts as a mediator between reasons and purchase intention in our model.
Originality/value
The escalating problem of electronic waste demands a shift toward sustainable consumer behavior with the help of social marketing. Hence, exploring the acceptance of remanufactured electronic products based on circular economy principles aligns with the goal of reducing waste generation. The remanufacturing literature on consumer behavior, which mainly benefits from the theory of planned behavior, overlooked the reasons for and against behavior. The authors base their study on behavioral reasoning theory, highlighting that reasons for and against behavior are critical in decision-making.

Abstract
Purpose
While the current knowledge in the field of educational leadership and management (EDLM) has been primarily based on research produced in English-speaking Western societies, there have been significant efforts by other societies to contribute to the knowledge production, especially during the past decade. The purpose of this paper is to identify the contribution of Turkey to the international EDLM literature by investigating the topical focus, conceptual frameworks and research designs of papers published by EDLM scholars from Turkey.
Design/methodology/approach
Descriptive content analysis method was employed to examine 315 empirical, review, conceptual and commentary papers published by Turkish scholars in core educational administration and Web of Science journals. The time period of the review left open-ended. However, in practical terms, it begins in the year 1994 when the first article from Turkey was published in any of the selected sources and ends at the end of 2018. Information relevant to the research was extracted from each article and was coded to facilitate quantitative analysis. Using Excel software, descriptive statistics including frequencies and percentages were provided for each research question.
Findings
Results show that Turkish EDLM scholars mostly rely on survey based quantitative research approach, employing advanced statistical techniques in the analysis of the data. However, mixed method and qualitative studies are relatively less common. Organizational behavior, school leadership and emotions stand out as most frequently used topics, while Turkish scholars are not interested in analyzing the educational outcomes such as student achievement and school improvement. Consistent with the findings related to topical foci, a large number of those who were interested in correlational studies examined the relationship between leadership roles and organizational behaviors.
Research limitations/implications
The data set only included journal articles and excluded conference proceedings, books and theses/dissertations. Nevertheless, the authors believe this review adds significantly to previous reviews of local EDLM journals conducted by Turkish scholars. The authors concluded that the Turkish scholars should direct their future research to exploring and better understanding the practices of Turkish principals in schools by: diversifying their research topics; incorporating more qualitative and mixed-method designs; and taking into account specific features of the culture and educational system in Turkey.
Practical implications
Based on the current higher education context, reducing scholars’ teaching load, diversifying research funding opportunities, and modifying access to tenure tracks seem necessary interventions to support EDLM research with strong ties to practice and to the sociocultural context. In addition, policy changes aiming professionalization of administrative positions and establishing some forms of formal training for school principalship are needed. Such changes can help transfer the knowledge produced by the Turkish EDLM researchers to the practice and provide solutions to problems related to school administration.
Originality/value
This paper will add to recent effort to identify how a developing nation outside Western perspective approaches the field, and contributes to the global knowledge base.

Abstract
Purpose
This study sought to provide an understanding of what a culturally contextualized model of instructional leadership looks like in Turkey, and how this differs from models disseminated in the USA.
Design/methodology/approach
This study employed qualitative meta-synthesis to systematically review the full set of 22 qualitative studies of instructional leadership in Turkey. A systematic synthesis strategy was applied to code the findings from each study to develop broad themes that describe key domains of principal instructional leadership practice.
Findings
The results showed that instructional leadership of school principals in Turkey is composed of four main dimensions and ten subdimensions. The main dimensions include: (1) emphasis on national goals and competition, (2) maintaining the learning environment, (3) motivating and enabling teachers, and (4) monitoring program alignment and test results.
Research limitations/implications
While broad dimensions of instructional leadership described in the international literature are relevant in Turkey, some practices used to enact those dimensions appear poorly aligned with the institutional–cultural context of Turkish schools. Thus, findings from this study support the assertion that the specific practices used to measure, assess and practice instructional leadership must be adapted to the context of a specific society.
Originality/value
This paper contributes to international efforts to develop a globally validated knowledge base in educational leadership and management.
