Abstract

This paper briefly describes an approach to determine the optimum magnetic circuit parameters to minimize low speed torque ripple for switched reluctance (SR) motors. For prediction of the torque ripple, normalized data obtained from field solution and a neural network approach is used. Comparison of experimental results with computations illustrates the accuracy of the method. The optimization method is briefly described and some results are presented.

Abstract

Purpose

The objective of this paper is to develop a comprehensive model of supply chain and supply chain decision‐making complexity that provides an understanding of the drivers of supply chain complexity and strategies to manage supply chain and supply chain decision‐making complexity and outcomes.

Design/methodology/approach

Grounded theory methodology is employed to build a theory of supply chain and supply chain decision‐making complexity and develop propositions related to antecedents, moderators, and outcomes of supply chain complexity. In addition, extensive literature review and informal interactions with a number of supply chain professionals have been used to validate the theory.

Findings

In addition to identifying the antecedents of supply chain complexity, the authors explore strategic, human cognitive ability, and tactical moderators for managing supply chain complexity.

Research limitations/implications

The comprehensive framework presented in the paper builds a theory of supply chain and supply chain decision‐making complexity that is grounded in empirical data. The research also incorporates disparate findings, constructs from multi‐disciplinary research on supply chain complexity and provides future research directions.

Practical implications

The research helps practitioners better understand the sources and outcomes of supply chain complexity and how to manage it. Various strategies to moderate the impact of supply chain complexity are presented.

Originality/value

An integrated, comprehensive theory of supply chain complexity is proposed along with definitions of supply chain complexity and supply chain decision‐making complexity. The proposed model is rooted in actual practice and supported by the existing literature.

Abstract

Purpose

The prenatal distress level of the pregnant woman is influenced by many variables. Personality characteristics are one of the most important of these variables. Knowing personality characteristics of pregnant women contributes to the personalization of care. The purpose of this paper is to identify the effect of personality characteristics of pregnant women at risk on the prenatal distress level.

Design/methodology/approach

A total of 438 women who were hospitalized based on a medical diagnosis associated with pregnancy were included in the study. The participants were administered the Personal Information Form, Cervantes Personality Scale and Revised Prenatal Distress Questionnaire. Data were evaluated using the SPSS 22.0 software program.

Findings

Of the pregnant women, 27.4 percent found their ability to cope with stress insufficient, and one-fifth of them found their social support insufficient. The pregnant women at risk with introverted, neurotic and inconsistent personality were found to have high levels of prenatal distress.

Research limitations/implications

This study was conducted on a group of Turkish pregnant women and cannot be generalized to other cultures. The data obtained from the research cannot be used to evaluate the psychological and physical disorders of the pregnant woman.

Practical implications

All health care professionals should evaluate women not only physically but also mentally and emotionally, beginning with the preconceptional period. They should determine the conditions that create distress and identify the personality characteristics that prevent from coping with stress. By using cognitive and behavioral techniques, pregnant women should be trained to gain skills on subjects such as risk perception and stress management, personality characteristics and coping, problem solving, psychological endurance and optimism. Caring initiatives should be personalized in line with personality characteristics of pregnant women. The care offered within this framework will contribute to the strengthening and development of the health of not only the women but also the family and society, and to the reduction of health care costs.

Social implications

Researchers have determined that pregnant women at risk with introverted, neurotic and inconsistent personality characteristics have higher distress levels. They have determined that these pregnant women find their ability to cope with stress more inadequate. It is vital to cope with stress during pregnancy due to its adverse effects on maternal/fetal/neonatal health.

Originality/value

The prenatal distress level of the pregnant woman is influenced by many demographic (age, marital status and socioeconomic level), social (marital dissatisfaction, and lack of social support), personal (self-esteem, neuroticism and negative life experiences) and pregnancy-related (experiencing risky pregnancy, and previous pregnancy experiences) variables. Personality characteristics are one of the most important of these variables. This research is original because there are limited number of studies examining the effect of personality characteristics on prenatal distress level in the literature. And knowing the relationship between personality characteristics and distress by health professionals enables individualization of care. The care offered within this framework will contribute to the strengthening and development of the health of not only the women, but also the family and society, and to the decrease of health care costs.

Abstract

Purpose

Fear of birth may cause perinatal complication, increased risk of intervention and need for analgesia, delayed mother–infant attachment process and deterioration of spouse relationship. The purpose of this study was to determine the affecting factors and childbirth fears of Turkish pregnant women.

Design/methodology/approach

This is a descriptive research type. The sample of this study consisted of 78 pregnant women who met the inclusion criteria and agreed to participate in this study. This study was carried out in a family health center and university hospital in a city in Turkey. Data were collected with Personal Information Form and Wijma Expectancy/Experience Scale-A Version (W-DEQ A).

Findings

The mean scores of pregnant women from W-DEQ A version were 75.60 ± 9.48. In 65.4% of pregnant women, fear of severe birth, 20.5% fear of clinical birth and 14.1% of children had a fear of moderate birth. W-DEQ A version, the third trimester, unplanned pregnancies, lack of knowledge of the level of inadequate birth and more than eight pregnancies in pregnancy, the total score of pregnant women was found to be higher (p < 0.05).

Research limitations/implications

The limitation of this study is its small sample size. Further studies with larger sample sizes are needed.

Practical implications

It was determined that one-fifth of the sample group experienced birth fear at the clinical level and childbirth fear level is associated with unplanned pregnancies, lack of knowledge. In antenatal period, the pregnant woman should be encouraged to express her feelings and thoughts about the labor and give information about the labor.

Social implications

Cognitive and behavioral education programs can be structured to cope with fear of birth for pregnant women at risk.

Originality/value

This research is original. This study presents data on Turkish women. The data can also be used to evaluate intercultural differences.

Abstract

Purpose

This study examines the international literature on sports events published between 1981 and 2024 within the framework of specific parameters.

Design/methodology/approach

The data were analyzed using quantitative and bibliometric analyses. Studies related to sports events were scanned through the Scopus database, and 1,072 studies were evaluated.

Findings

It has been revealed that the highest number of studies related to sports events were published in 2021, with Tichaawa, T.M. being the author with the most publications. Griffith University conducted the most studies on this topic, and the United States had the highest number of publications. Additionally, the findings indicate that the number of studies on sports events is increasing, with more studies being conducted in business and social sciences. Regarding keyword usage frequency, the studies focus on destination image, economic impact, and sustainability. Clustering analysis results show that the studies are divided into four clusters, focusing on sports, tourism, and tourism development.

Research limitations/implications

Due to methodological limitations, the results of bibliometric analysis generally focus on metrics related to articles, sources, and authors. Another limitation is the examination of studies in the context of tourism that are published in the international literature and accessible only through the Scopus database in English. An additional limitation is that the publications analyzed in this study are specifically on sports events. This study aims to fill a gap in the field by examining sports event studies in the international literature, thereby providing researchers with a holistic perspective. It is considered significant as it will offer a different viewpoint on bibliometric studies related to sports events and sports tourism in the international literature, both in terms of the parameters used in the study and the study’s focus.

Originality/value

It is believed to be important because it is the first bibliometric study explicitly conducted on sports events.

Abstract

Purpose

This paper aims to examine the current state of reverse supply chain management (RSCM) initiatives in several Turkish industries.

Design/methodology/approach

This study is based on an exploratory research regarding RSCM activities of Turkish automotive, white goods, electric/electronics, and furniture industries. The sample consists of all the companies included in the Top‐500 Industrial Enterprises List of The Assembly of the Istanbul Chamber of Industry (ISO).

Findings

The research findings show that the RSCM initiatives in the considered industries are still in a very early stage. Companies' involvement in product returns is mostly due to the legislative liabilities, and system inadequacies are emphasized as the most important reason for not being able to implement an efficient RSCM.

Research implications/limitations

This paper investigates the reverse supply chain practices of selected industries in Turkey and aims to enable researchers to use this study as a building block in understanding these practices and related problems. The limitation of this study is to solely include the medium and large‐sized companies in the industries.

Practical implications

Reverse supply chain operations contribute to the economic sustainability by reducing waste and saving energy and material. In this research, an empirical study in the electronics, white goods, automotive and furniture industries is conducted, and potential research opportunities are discussed to streamline reverse supply chain activities in the industries. Hence, this study can be viewed as an attempt to increase the level of awareness on reverse supply chain issues.

Originality/value

No field study has been conducted to analyze reverse supply chain activities of the industries in Turkey. This research is a pioneering study and will provide a benchmark for the various research activities on related topics.

Abstract

Purpose

The purpose of the study is to provide a dataset about geometrical constructions of early Ottoman tombs for conservation studies. Thus, a proposal for the restitution phase of the damaged tombs aims to develop.

Design/methodology/approach

The study is composed of four phases. First, the representative plan and section drawings of early Ottoman Tombs were redrawn; second, a geometrical analysis was made, a proposal table was prepared for the restitution of the damaged tombs; and last, this table was applied to tomb examples and restitution drawings are verified with the original situation of the tombs.

Findings

Early Ottoman tombs may be interpreted through geometric shapes, including the square, circle, triangle, octagon, arsin grid and quadrature systems. The arsin grid system provides information about the position of the domes and the height of the drums and windows. Quadrature establishes the highest point of domes and entrances. The proposal table, developed from the obtained results, facilitated the identification of the original elements, including the dome, drum, window and portal. This information is crucial for conducting further studies on restitution.

Originality/value

The abundance and dispersed nature of tomb structures compared to other architectural designs pose challenges in their scholarly examination. The early Ottoman tombs, which experienced an increase in numbers following the Conquest of Istanbul, serve as the initial expressions and embodiments of novel architectural endeavors. Thus, the determination of design ideas of the early Ottoman tombs sheds light on Ottoman architectural practice, which has remained largely unknown and guided the conservation studies of the tombs that have lost their integrity and originality.
