Abstract
Purpose
This study aims to perform the surface treatment of synthetic α-Fe2O3 red iron oxide pigment with hydrolysate 3-aminopropyl silane (A) and colloidal silica (CS) and investigate the effects of surface-treated pigment on the styrene acrylic (SA) emulsion and polyurethane (PU) dispersion.
Design/methodology/approach
For this purpose, firstly red iron oxide particles were modified with A and CS separately in an aqueous medium. After isolation of the modified iron oxide were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS). Moreover, the degree of the dispersion stability of the modified pigment in coatings with SA emulsion and PU dispersion was investigated by using an oscillation rheometer. Loss (G''), storage (G') modulus, loss factor [tan(δ)] and yield stress (τ0) values were determined by performing amplitude and frequency sweep tests.
Findings
The τ0 in SA coatings decreases with the amount of used A and increases with the amount of used CS. The τ0 decreases as the amount of used A and CS in PU coatings increases. The use of CS on red iron oxide pigments causes storage modulus to increase in SA coatings at low angular frequencies, while it causes a decrease in PU coatings.
Originality/value
To the best of the authors’ knowledge, for the first time, the suspended state of the iron oxide hybrid pigment formed with CS in the coating was investigated rheologically in this study.

Abstract
Special interest tourism (SIT) is a specialized type of tourism. People aim to visit destinations with a specific theme through this type of tourism. During SIT consumption, they create or develop peculiar interests and participate individually or in groups. In this respect, SIT is a concept that reflects some trends. These trends developed toward satisfying different interests rather than those developed around mass tourism. In other words, SIT emerges as an alternative movement to mass tourism based on general interests. Soon after mass tourism gained extensive dimension, alternative tourism, ecotourism, and SIT concepts emerged. These concepts altered the style of tourism operations. Diversified tourism operations have transformed conventional tourism into experience-based tourism activities. Presentations of these types of experiences are frequently in the form of special interests. The content of this chapter encompasses the fundamental concepts forming the SIT. An overview of the terminology – such as alternative tourism, sustainable development, and sustainable tourism – is the scope of this chapter. Moreover, criticisms and some trends in SIT are the leading subtopics. Some examples of academic research about SIT in Turkey are listed in the current study. This list was compiled from the information gathered from the Council of Higher Education National Thesis Center Database records.

Abstract
Purpose
This study aims to investigate preschool teachers' perspectives on diversity in the unique educational context of Türkiye, a nation-state often underrepresented in the predominantly Western-centric diversity literature.
Design/methodology/approach
Recognizing teachers as critical content integrators, the study involved semi-structured interviews to explore their views on diversity within early childhood education.
Findings
Analysis of the interviews revealed two key themes: first, the challenge of maintaining nation-state ideology, where teachers balance fostering a national identity with acknowledging diverse cultural backgrounds; and second, a willingness among educators to embrace diversity, highlighting their efforts to create inclusive, multicultural classrooms.
Practical implications
The authors call for developing context-specific teacher education programs addressing diversity in depth, equipping teachers to effectively promote context-specific multicultural education that would be different from Western countries.
Originality/value
To the best of the authors’ knowledge, this study is original in researching preschool teachers’ understandings of multicultural education in a nation-state country.

Abstract
Purpose
Down syndrome is one of the common genetic causes of intellectual disability. Adult with Down syndrome may have many psychiatric comorbidities. Therefore, their mental health status should be considered in legal proceedings such as criminal responsibility and legal capacity where they are involved. This study aims to highlight that individuals with Down syndrome are often referred directly to forensic psychiatry without undergoing an interview, despite the fact that this is a group with varied mental statuses.
Design/methodology/approach
This study analysed the socio-demographic, clinical and forensic characteristics of eight adult individuals with Down syndrome for whom the Council of Forensic Medicine (CFM) requested an opinion on criminal liability and other legal situations between 2018 and 2022. The CFM is an authoritative institution to which cases from all areas of Türkiye are referred.
Findings
The mean age of the individuals with Down syndrome for whom a forensic psychiatric opinion was requested was 24.63 (±7.95) and the mean IQ level was 54.13 (±13.38). All cases were male, 6 / 8 were referred for assessment of criminal responsibility and 4 / 6 of those referred for assessment of criminal responsibility were referred for sexual offences. It was found that 5 / 8 of the cases had moderate intellectual disability and 3 / 8 of the cases had mild intellectual disability.
Research limitations/implications
Regarding the limitations of this study, the first one is the small sample size. Nevertheless, due to the low prevalence of people with Down syndrome in society, it is plausible that their stigmatization may not be reflected in the judicial system, even in cases involving violent behaviour. The second limitation is that the reports lack all psychiatric medical documents, including forensic psychiatric evaluations of individuals with Down syndrome. Additionally, additional diseases were recorded based on familial anamnesis. The third limitation is that this study is the first publication to investigate Down syndrome from a forensic psychiatric perspective. Thus, there is a lack of literature to make direct comparisons and references in the discussion section.
Social implications
This is the first study about forensic psychiatric aspects for people with Down syndrome. The aim of this study was to examine the forensic psychiatric approach in Down syndrome, one of the most common genetic causes of intellectual disability, the situations in which forensic psychiatric assessment is required and the issues that might be considered important in this regard. Although there are various publications in the literature on the psychiatric conditions of individuals with Down syndrome, to our knowledge, this is the first study to evaluate individuals with Down syndrome in terms of forensic psychiatric evaluation. People with Down syndrome are known to have varying degrees of intellectual disability and different types of psychiatric comorbidity.
Originality/value
People with Down syndrome are a heterogeneous group in terms of intellectual disability. The criminal responsibility and legal capacity of individuals may vary according to the legal situation. When requesting forensic psychiatric evaluation of these patients with psychiatric co-morbidity, patients should not be prejudged in terms of their level of mental competence and each case should be assessed individually.

Abstract
Purpose
Considering both the current opportunities of the Internet of things (IoT) and aviation, as well as the potential opportunities they may offer for the future, it is understood that they are among the important issues that need to be examined in the literature. This study aims to provide an idea by conducting bibliometric and visualization analyses of the current trends and development opportunities of IoT and aviation.
Design/methodology/approach
In this study, descriptive and bibliometric analyses within the framework of co-author, co-citation, bibliographic coupling, and keyword co-occurrence analysis were carried out for publications found to be published between 2007 and 2023 in the Web of Science (WoS) database related to IoT and aviation. VOSviewer (ver. 1.6.18) program and the Biblioshiny application were used to create bibliometric networks and provide visualization.
Findings
As a result of some descriptive and visualization analyses, the current trend of publications on IoT and aviation and future publication opportunities has been revealed. It has been understood that the subject of IoT and aviation is one of the subjects whose number of publications has increased in recent years and has not yet fully matured in terms of the number of publications and has the potential to make new publications.
Originality/value
In this study, bibliometric analysis of IoT and aviation, which could not be found examined before in the literature, and the creation of existing bibliometric networks by visualizing were carried out.

Abstract
Purpose
This study examines the determinants of idiosyncratic risk (IR) or unsystematic risk. The study also examines the determinants of IR by dividing the firms into different categories: beta-based firms, liquid and illiquid firms and financially constrained (FC) and unconstrained (FUC) firms.
Design/methodology/approach
The fixed effects static panel data model specifications are formulated based on Hausman (1978) test for BRICS (Brazil, Russia, India, China, and South Africa) member countries over the period 2000–2019. Moreover, the t-test is applied to see whether the returns of different types of portfolios are significantly different.
Findings
The portfolio analysis results show that, on average, high IR firms tend to be small in size, highly leveraged, have low competitiveness, low profitability, less dividend yield and low returns for all the sampled countries. The sample paired t-test also confirms that a significant difference exists between extreme portfolios: small and large size and low IR and high IR portfolios. The panel regression results show that firm size, market power, price-to-earnings ratio, return on equity (ROE) and dividend yield negatively relates to IR. Yet, both leverage and liquidity are positively related to IR. However, the sign of momentum returns is mostly positive for the entire sample. The coefficient values for high-beta, FC and illiquid firms are more significant and large than the firms' counterparts for all BRICS member countries. These results support the hypothesis of an under-diversified portfolio and suggest that the above-mentioned firm-specific variables are the significant determinants of unsystematic risk.
Practical implications
The securities exchange commission, as the supervisor of the public limited companies, needs to increase its role in investor protection related to the uncertainty of investment in the capital market. Accordingly, in making investment decisions in a stock exchange, investors can use the information that captures unsystematic risk for investment decision-making.
Originality/value
This study is the first to explore the determinants of IR in top emerging countries. Second, none of the existing studies has focused on the determinants of the IR based on different categories of firms.

Abstract
Purpose
This study aimed to explore the adaptations and perspectives of hotel managers regarding green and smart hotel technologies within the context of sustainability.
Design/methodology/approach
A comprehensive literature review guided the formulation of this study, followed by face-to-face, semi-structured interviews with hotel managers. A total of 17 prepared questions were finalized after examination by two expert academicians. The responses were analyzed using qualitative research methodology and the results were weighted using the step-wise weight assessment ratio analysis (SWARA) method.
Findings
Interviews with sustainability and operational managers yielded insights into environmentally friendly practices and strategies such as reducing energy and water consumption, waste and chemical reduction, supporting local entrepreneurs and adopting smart technologies. These factors are crucial in eco-friendly hotels. According to the SWARA analysis, 'reducing energy consumption' is the most effective criterion.
Research limitations/implications
This study offers insights into green and smart hotel management by focusing on the perspectives of hotel managers with a small sample. In future studies, research with larger samples on customer perspectives and the effect of hotel selection is recommended.
Practical implications
This study offers insights to hotel managers on energy conservation and customer satisfaction enhancement through green and technological applications. These technological applications can improve hotel service quality and provide personalized experiences, fostering customer loyalty.
Originality/value
This pioneering study focuses on the intersection of green and smart practices in hospitality. By intertwining the often separately discussed concepts of “green” and “smart,” this study presents a novel approach to the sustainability practices in the hospitality industry, holding a key position, especially in Turkey. Implementing these concepts can yield environmental and economic benefits, offering invaluable insights to hotel managers and policymakers into integrating smart technologies with sustainability.

Abstract
Purpose
The objective of this study is to explore Generation Z’s interpretation of educational practices at the secondary education level. By examining the expectations of Generation Z, this study aims to provide insights for teachers and decision-makers to improve educational and instructional practices.
Design/methodology/approach
The specific approach employed in this study is Transcendental Phenomenology (TPh), which focuses on uncovering the perceived experiences, thoughts and evaluations of the Gen Z generation toward formal education. For this study, the maximum variation sampling strategy, which is one of the purposive sampling methods, was utilized. In line with the nature of the design, one-on-one interviews were conducted to collect data. Thematic analysis, a commonly used method for identifying recurring patterns of meaning, was applied to analyze the data. Peer debriefing or analytic triangulation, Data saturation, Triangulation and member checking techniques were operated to support the validity and reliability of the study.
Findings
In the light of the data analysis, four themes emerged: expectations from teachers, curricula, school administration and School Counseling Service (SCS). Gen Z expects from teachers “to be democratic, to adopt novel teaching approaches and technology, to have affective qualities, to be attentive to arts and sports, to conduct qualified assessment.” Gen Z has also expectations regarding the curricula in practice such as “functionality, extracurricular activities, and instructional practices.” The expectations of the students from school administration include “administrative expectations,” “expectations regarding the learning environment” and “social expectations.” The participants had expectations regarding School Counseling Service (SCS) such as “professional guidance,” “academic guidance” and “career guidance.” “Career guidance” includes “introduction of career paths,” “academic guidance” includes “introduction of university programs,” “exam guidance” and “teacher training” and “personal guidance” includes “accessibility,” “equity in guidance services,” “communication” and “functionality.”
Research limitations/implications
The research is limited to the volunteers included in the study. In addition, the study includes only senior high school students, 12th graders, representing Gen Z. In addition, the study includes only Gen Z living in a metropolitan city. The methodological limitation of the study is that only one-to-one interview technique was used for data collection. The main reason behind such a choice is that the most appropriate technique for data collection in the phenomenology method is one-on-one interviews in order to explore individual interpretation.
Practical implications
The research sheds light on many different points in terms of different applications. One of the results obtained in this context is curriculum. Gen Z criticizes the limitation of the program to only in-school learning and states that extracurricular practices should be included. Findings also presents implications regarding learning environments. There is a growing emphasis by Gen Z on the adoption of green, comfortable and interactive learning spaces. The Generation Z population expects teachers to possess digital competence (DC) and utilize it in their teaching practices. This shows that teachers' teaching competencies need to be upskilled.
Social implications
It is crucial for policymakers to support the development of teachers' digital skills and encourage their integration into teaching to enhance instructional productivity, promote innovative learning, increase instructional appeal, foster teamwork, improve communication and facilitate innovative learning. The research reveals that Gen Z is a social phenomenon and needs to be recognized and their learning needs explored. In this context, it is imperative that the preferences and learning needs of Gen Z are considered in the learning environment, content, method-technique and assessment stages, especially in formal education practices.
Originality/value
The current research is important both in terms of filling the research gap in the literature and making inferences about the learning preferences of the GEN Z generation. In addition, it raises awareness in terms of the return on educational investments, providing sustainable motivation for learning and school and increasing the quality of learning outcomes. While the study reveals certain implications, further research is required to investigate the competencies of teachers, the effectiveness of teaching materials, instructional practices and designs and learning environments. Future studies should particularly concentrate on the personal preferences, motivation, engagement and learning preferences of Gen Z at the secondary level. Authorities, including teachers, ought to reassess their perspectives and adapt their practices in order to better meet the needs and expectations of Gen Z.
