Abstract
Purpose
In performative architectural design, daylighting is a crucial design consideration; however, the evaluation of daylighting in the design process can be challenging. Immersive environments (IEs) can create a dynamic, multi-sensory, first-person view in computer-generated environments, and can improve designers' visual perception and awareness during performative design processes. This research addresses the need for interactive and integrated design tools for IEs toward better-performing architectural solutions in terms of daylighting illumination. In this context, building information modeling and performance simulations are identified as critical technologies to be integrated into performative architectural design.
Design/methodology/approach
This research adopts a design science research (DSR) methodology involving an iterative process of development, validation and improvement of a novel and immersive tool, HoloArch, that supports design development during daylighting-informed design processes. HoloArch was implemented in a game engine during a spiral software development process. HoloArch allows users to interact with, visualize, modify and explore architectural models. The evaluation is performed in two workshops and a user study. A hybrid approach that combines qualitative and quantitative data collection was adopted for evaluation. Qualitative data analyses involve interviews, while quantitative data analyses involve both daylighting simulations and questionnaires (e.g. technology acceptance model (TAM), presence and system usability scale (SUS)).
Findings
According to the questionnaire results, HoloArch had 92/100 for SUS, a mean value of 120.4 for presence questionnaire (PQ) and 9.4/10 for TAM. According to the simulation results, all participants improved the given building's daylighting performance using HoloArch. The interviews also indicated that HoloArch is an effective design tool in terms of augmented perception, continuous design processes, performative daylighting design and model interaction. However, challenges still remain regarding the complete integration of tools and simultaneous simulation visualization. The study concludes that IEs hold promising potentials where performative design actions at conceptual, spatial and architectural domains can take place interactively and simultaneously with immediate feedback.
Originality/value
The research integrates building information modeling (BIM), performative daylighting simulations and IEs in an interactive environment for the identification of potentials and limitations in performative architectural design. Different from existing immersive tools for architecture, HoloArch offers a continuous bidirectional workflow between BIM tools and IEs.

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
The aim of the study is to contribute to the body of knowledge with a different and richer approach, by evaluating the competitiveness of the Cappadocia Region, which has a culture-oriented single or limited product variety, with a comparative and holistic approach from the perspective of visitors and stakeholders.
Design/methodology/approach
This research, designed on the basis of the Cappadocia Region to make original and rich contributions to the literature on destination competitiveness, has the characteristics of a field study based on collecting and analyzing raw data through scales. For this purpose, research was conducted with 401 visitors and 277 tourism stakeholders. Data was analyzed using t-tests to compare two groups and the two-way analysis of variance (ANOVA) to compare more than two groups. Cronbach's alpha analysis, nomological validity and a pilot test were conducted for validity and reliability. In addition, descriptive statistics and normality test were used in addition to the exploratory factor analyses.
Findings
Because of the research, it was seen that the competitiveness perceptions of the participants in the region differed and that the region has many strengths such as natural beauties, accommodation facilities and a positive image. However, it was determined that the competitiveness perceptions of visitors who have more touristic experiences in the region have increased in parallel with their touristic experiences. It was established that the competitiveness perceptions of the stakeholders who have comprehensive knowledge of the managerial problems and the destination competitiveness components of the region are generally lower than the visitors.
Practical implications
This study provides some practical implications for touristic destinations based on the research area. In order for destinations to survive in a fierce competitive environment and strengthen their competitive position, it is very important to analyze and evaluate consumers' needs and requests correctly, reveal existing differences, and use resources effectively. In addition to strengthening the image of the destination and adopting a sustainable and innovative approach, the integrated tour programs that offer touristic activities in nearby cities can be diversified with nature and adventure activities.
Originality/value
It is seen that studies that have been conducted with a comparative and holistic approach with data obtained from both visitors and stakeholders are quite limited. In addition, most of these studies have been conducted on destinations that are widely preferred such as mass tourism but which are less competitive than alternative tourism examples. Therefore, this study has a broad perspective and strong implications for destination competitiveness.

Abstract
Purpose
Today, e-government (electronic government) applications have extended to the frontiers of health-care delivery. E-Nabız contains personal health records of health services received, whether public or private. The use of the application by patients and physicians has provided efficiency and cost advantages. The success of e-Nabız depends on the level of technology acceptance of health-care service providers and recipients. While there is a large research literature on the technology acceptance of service recipients in health-care services, there is a limited number of studies on physicians providing services. This study aims to determine the level of influence of trust and privacy variables in addition to performance expectancy, effort expectancy, social influence and facilitating factors in the unified theory of acceptance and use of technology (UTAUT) model on the intention and behavior of using e-Nabız application.
Design/methodology/approach
The population of the study consisted of general practitioners and specialist physicians actively working in any health facility in Turkey. Data were collected cross-sectionally from 236 physicians on a voluntary basis through a questionnaire. The response rate of data collection was calculated as 47.20%. Data were collected cross-sectionally from 236 physicians through a questionnaire. Descriptive statistics, correlation analysis and structural equation modeling were used to analyze the data.
Findings
The study found that performance expectancy, effort expectancy, trust and perceived privacy had a significant effect on physicians’ behavioral intentions to adopt the e-Nabız system. In addition, facilitating conditions and behavioral intention were determinants of usage behavior (p < 0.05). However, no significant relationship was found between social influence and behavioral intention (p > 0.05).
Originality/value
This study confirms that the UTAUT model provides an appropriate framework for predicting factors influencing physicians’ behaviors and intention to use e-Nabız. In addition, the empirical findings show that trust and perceived privacy, which are additionally considered in the model, are also influential.

Abstract
Purpose
From 1979 to 2023, the takaful structure has been adopted in many jurisdictions, making the documenting of its early days of establishment relatively difficult and somewhat unreliable. This is unlike conventional insurance, where the history and legislation are well documented and archived in various research (Hellwege, 2016; Marano and Siri, 2017). The purpose of this paper is to provide a chronology for the establishment and development of takaful via the takaful establishment in each jurisdiction, documenting its first takaful operator and first takaful regulation.
Design/methodology/approach
This paper has used a qualitative method in the form of reviewing literature and available data such as journals, books and official resources. The data is thoroughly analysed in order to build the chronology for takaful. It adopted an exploratory research design, which is deemed suitable in situations where few works of literature have examined the subject (Neuman, 2014). The paper explores the establishment and non-establishment of takaful in 57 countries. The paper categorises the countries into seven regions starting with the GCC, Levant, Asia, Central Asia, Africa, Europe and Others.
Findings
The takaful chronology presented in this paper shows that takaful operations exist in 47 jurisdictions, starting from Sudan and the UAE in 1979, with the most recent adopters being Morocco and Iran in December 2021. It is found that 22 jurisdictions do not have takaful regulations, and the Takaful Act 1984, issued in Malaysia, is considered the first takaful regulation that sets the basis for other regulations that follow.
Originality/value
The paper contributes to the literature by providing a comprehensive chronology of takaful, especially as the few existing timelines have been found to be incomplete and consist of contradictory information.
