Abstract
Purpose
This paper aims to present a single-block memory-based FFT processor design with a conflict-free addressing scheme for field-programmable gate arrays FPGAs with dual-port block memories. This study aims for a single-block dual-port memory-based N-point radix-2 FFT design that uses memory locations and spending minimum clock cycle.
Design/methodology/approach
A new memory-based Fast Fourier Transform (FFT) design that uses a dual-port memory block is proposed. Dual-port memory allows the design to perform two memory reads and writes in a single clock cycle. This approach achieves low operational clock and smallest memory simultaneously, excluding some small overhead for exceptional address changes. The methodology is to read from while writing to a memory location, eliminating the need for excess memory and additional clock cycles.
Findings
With the minimum memory size and the simplest architecture, radix-2 FFT and single-memory block are used. The number of clock pulses spent for all FFT operations does not provide much advantage for low-point FFT operations but is important for high-point FFT operations. With the developed algorithm, N memory is used, and the number of clock pulses spent for all FFT stages is (N/2 +1)log2N for all FFT operations.
Originality/value
This is an original paper, which has simultaneously in whole or in part been submitted anywhere else.

This paper aims to examine the relationships between locus of attribution, recovery justice perceptions, recovery satisfaction and repurchase intention after a B2B service failure.
Abstract
Purpose
This paper aims to examine the relationships between locus of attribution, recovery justice perceptions, recovery satisfaction and repurchase intention after a B2B service failure.
Design/methodology/approach
Structural equation modeling was used to analyze 300 customer surveys from hospitality businesses. The connections between the selected variables were explored through path analysis using AMOS 24.
Findings
Based on the results, the more that business customers blame their wholesalers after a service failure, the less they perceive the procedures in the recovery process as fair. Findings also indicate that in the recovery process, interactional connections through fair treatment and inclusion of customer opinions are important to achieve high recovery satisfaction levels. Moreover, if business customers perceive the monetary compensation provided as fair, their recovery satisfaction increases, and recovery satisfaction then helps to retain these business customers after a service failure.
Research limitations/implications
Starting from the locus of blame, this study highlights the after-failure calculation that business customers make in considering their recovery justice perceptions and the resulting satisfaction level.
Practical implications
The findings have relevance for B2B relationships. This study provides practical processes for failure and recovery management in B2B settings, especially for wholesale providers who function as resellers rather than as manufacturers.
Originality/value
The contributions from this study are largely due to examining B2B service failure and recovery as a process that starts at the pre-recovery stage with the locus of attribution followed by recovery justice perceptions. Whereas other studies have focused more on justice perceptions, the authors go back a step in the recovery process to better understand the antecedents of repurchase intention in B2B transactions.

Abstract
Purpose
This paper aims to provide a comprehensive understanding of factors that contribute to refugees’ exclusion from health-care services. More specifically, using institutional theory, this paper identifies regulative pillar-, normative pillar- and cultural/cognitive pillar-related challenges that result in refugees having limited or no access to health-care services.
Design/methodology/approach
The paper draws on both secondary research and empirical insights from two qualitative fieldwork studies totaling 37 semi-structured meso-level interviews, observations and focus groups in three Turkish cities (Izmir, Ankara and Edirne), as well as a total of 42 micro-level, semi-structured interviews with refugees and migrants in one large city (Izmir) in Turkey.
Findings
This study reveals that systematically stratified legal statuses result in different levels of access to public health-care services for migrants, asylum seekers or refugees based on their fragmented protection statuses. The findings suggest access to health-care is differentiated not only between local citizens and refugees but also among the refugees and migrants based on their legal status as shaped by their country of origin.
Originality/value
While the role of macro challenges such as laws and government regulations in shaping policies about refugees have been examined in other fields, the impact of such factors on refugee services and well-being has been largely ignored in service literature in general, as well as transformative service research literature in particular. This study is one of the first attempts by explicitly including macro-level factors to contribute to the discussion on the refugees’ access to public health-care services in a host country by relying on the institutional theory by providing a holistic understanding of cognitive, normative and regulative factors in understanding service exclusion problem.

Abstract
Purpose
The tribological behavior of composites varies on matrices materials, the reinforcement material and the direction of reinforcement materials. The purpose of this study is to examine the effects of fiber orientation on the tribological properties of carbon fiber–reinforced epoxy composite.
Design/methodology/approach
The experiments were carried out with a pin-on-ring tribometer. The tests were executed according to three different parameters: load, sliding velocity and direction of reinforcement. Loads measuring 92 N and 150 N were applied at sliding velocities of 1 and 2 m/s, in parallel, antiparallel and normal directions of fiber reinforcements. The frictional force was read every 500 m of sliding distance. To calculate specific wear rate, the mass of the samples was measured before and after each experiment. Moreover, temperature was measured every 1000 m of sliding distance via three-point infrared thermometer, to examine the effect of temperature variations. The sample surfaces were also examined in optic microscope after the experiments. Higher friction coefficient values were obtained in the normal direction-oriented carbon fiber specimen.
Findings
Comparing the friction coefficient values, antiparallel and parallel direction-oriented carbon fiber specimens gave lower friction coefficient values. The increase of sliding velocity and normal load resulted in the increase of surface temperature and this lead to the increase of friction coefficient.
Originality/value
This study shows the effects of fiber orientation on the tribological behavior of carbon fiber–reinforced epoxy composite. According to fiber orientations, relatively moving counter surfaces of this material shows different tribological behaviors.

Abstract
Purpose
This study aims to examine the dietary compliance of children and adolescents with celiac disease (CD) and their diet quality (DQ) and dietary acid load (DAL) and to determine the relationship of these dietary parameters with health-related quality of life (HRQoL).
Design/methodology/approach
Ninety-one children and adolescents with CD and 144 healthy peers were included in this cross-sectional study. Anthropometric measurements were conducted by researchers. DQ and DAL were calculated from participants’ 24-h dietary recall records. HRQoL was assessed using the Pediatric Quality of Life Inventory, and compliance with a gluten-free diet (GFD) was obtained using the GFD score. Data was collected through a face-to-face questionnaire.
Findings
Of celiac patients, 53.1% were strictly compatible with the GFD, and 35.8% were non-compliant with the diet. The DQ scores of participants with CD were higher than their healthy peers, and the DAL scores were lower (p < 0.01). Finally, no relationship was found between the DQ and DAL with HRQoL scores in celiac patients (p > 0.05). However, better dietary compliance with the GFD was associated with improved HRQoL (p < 0.05).
Practical implications
While DQ and DAL had no association with HRQoL, better dietary compliance improved the HRQoL of celiac patients. This may help develop solutions to the problems experienced by celiac patients, thereby improving the management of CD.
Originality/value
To the best of the authors’ knowledge, this study is the first to investigate the association of DQ and DAL with HRQoL in children with CD.

Abstract
Purpose
This study aims to evaluate level of fear and the tendency toward orthorexia nervosa (ON) during the COVID-19 pandemic in the university students receiving health education.
Design/methodology/approach
A total of 765 students, consisting of 626 females (81.8%) and 139 males (18.2%) were included in the study. The demographic characteristics, anthropometric measurements, Eating Attitude Test-26 (EAT-26), Fear of COVID-19 Scale (FCV-19S) and the tendency toward ON were assessed using an online questionnaire.
Findings
The FCV-19S scores differed according to gender and were higher in the female students (P < 0.001). In students with a high EAT-26 score, the tendency toward ON was higher (P < 0.001). According to estimated regression models, a unit increase of the FCV-19S scores led to a decrease of 0.10 points in the Orthorexia Nervosa Evaluation Scale-11 (ORTO-11) scores. It was determined that students with high FCV-19S scores had a tendency toward ON and increased EAT-26 scores (P < 0.001 and P = 0.004, respectively). There was a weak negative correlation between the FCV-19S score and the ORTO-11 score (P < 0.001) and a weak positive correlation between the FCV-19S score and the EAT-26 score (P = 0.001).
Originality
In this cross-sectional study, it was determined that the fear of COVID-19 was related to an increase in the tendency toward ON and eating attitude in students receiving health education. Because of the fear and ON tendencies of students due to the COVID-19 pandemic, it would be beneficial to provide education on adequate and balanced nutrition during this period.

Abstract
Purpose
This study aims to determine the ranking of the 81 provinces at the NUTS-3 level in Turkey with respect to the personal satisfaction and public services satisfaction by applying Fuzzy Multi-Criteria Decision-Making methods to the Life Satisfaction Survey Results.
Design/methodology/approach
Fuzzy TOPSIS, Fuzzy MULTIMOORA and Fuzzy ARAS are implemented to assess life satisfaction of the individuals who lived in provinces, based on Life Satisfaction Survey 2013 for Turkey’s national comparison. In the solution process, 14 indicators for personal satisfaction and 38 indicators for public services satisfaction were considered.
Findings
The results showed that personal health satisfaction, earnings from work satisfaction and monthly income satisfaction are the most important criteria in terms of personal satisfaction. Also, healthcare services satisfaction, judicial services satisfaction and education services satisfaction have the highest importance in terms of public services satisfaction. The final ranking of the 81 provinces is obtained by considered methods. According to the ranking results, there is no significant difference between the east and the west part of Turkey in terms of personal satisfaction, whereas there is a distinct difference between them in terms of satisfaction with public services.
Originality/value
This study is the first research for evaluating the ranking of the provinces at the NUTS-3 level in Turkey according to the Life Satisfaction Survey 2013 results considering 14 indicators for personal satisfaction and 38 indicators for public services satisfaction by using FMCDM approaches that have not been applied before.

Abstract
Purpose
Three different pedagogical approaches grounded in three different definitional foundations of entrepreneurship have been compared in relation to their effects on students. They are: (1) “Idea and Artefact-Creation Pedagogy” (IACP), grounded in opportunity identification and creation, (2) “Value-Creation Pedagogy” (VaCP), grounded in value creation and (3) “Venture-Creation Pedagogy” (VeCP), grounded in organisation creation.
Design/methodology/approach
Data were collected at 35 different sites where education was deemed to be entrepreneurial and experiential. A quantitative, smartphone app-based data collection method was used alongside a qualitative interview approach. 10,953 short-survey responses were received from 1,048 participants. Responses were used to inform respondent selection and discussion topics, in 291 student and teacher interviews. Comparative analysis was then conducted.
Findings
The three approaches resulted in very different outcomes, both in magnitude and in kind. VaCP had strong effects on entrepreneurial competencies, on student motivation and on knowledge and skills acquisition. VeCP had weaker effects on knowledge and skills acquisition. IACP had weak effects on all outcomes probed for. Differences were attributed to variation in prevalence of certain emotional learning events and to variation in purpose as perceived by students.
Research limitations/implications
VaCP could serve as an escape from the potential dilemma faced by many teachers in entrepreneurial education, of being caught between two limiting courses of action; a marginal VeCP approach and a fuzzy IACP one. This could prompt policymakers to reconsider established policies. However, further research in other contexts is needed, to corroborate the extent of differences between these three approaches.
Originality/value
Most impact studies in experiential entrepreneurial education focus only on organisation-creation-based education. This study contributes by investigating entrepreneurial education that is also grounded in two other definitional foundations. Allowance has been made for novel comparative conclusions.

Abstract
Since 2004, Turkish cinema has been witnessing an emergence of horror genre, now flooded with stories of possession by malevolent jinn, as transgressive, volatile figures of abjection. These female-centred narratives rely both on Islamic cosmology and myths and folktales of pre-Islamic Anatolian oral culture. The chapter will first explore the reasons horror has been neglected in the century-long history of cinema in Turkey and move on to highlight the socio-economic, cultural, and political contexts that were catalysts for the horror genre’s emergence. Then, the chapter will discuss the codes and conventions of the genre and explore the unique place of Alper Mestçi’s 2007 film Haunted (Musallat), among its contemporaries in terms of the ways in which the film challenges these established codes and conventions. In analysing Haunted, the chapter will use the theoretical framework of Barbara Creed, Carol J. Clover and Julia Kristeva to discuss the monstrous-feminine and masculinity as abjection.
