The purpose of this study is to enable the planning of construction projects with simultaneous consideration of time, cost and safety risks. It also aims to improve the decision-making process by evaluating the effectiveness of the Rao-2 algorithm in solving multi-objective time-cost-safety risk problems. In the end, this model is designed to support project managers in enhancing management approaches by addressing project challenges and constraints more efficiently.

In this study, the Rao-2 algorithm, along with Grey Wolf Optimization (GWO) and Whale Optimization algorithm (WOA), were improved using the crowding distance-based non-dominated sorting method. Rao-2 was first compared to GWO and WOA. Subsequently, it was compared with well-established algorithms in the literature, including genetic algorithm (GA), particle swarm optimization (PSO) and differential evolution (DE). The C-metric, hypervolume and spread metrics were employed for performance measurement. The performance of the algorithms was evaluated on four case studies consisting of 11, 13, 18 and 25 activities.

The results revealed that Rao-2 performs better than other algorithms as the number of activities increases, when compared using the Hypervolume, Spread and C-metric measures. In terms of performance measures, the GWO algorithm outperformed Rao-2 in some evaluation metrics for the instance involving 11 activities. However, as the number of activities grew, the Rao-2 method consistently generated higher-quality Pareto fronts and outperformed GWO and WOA in all evaluation metrics. The solutions generated by Rao-2 were also superior to those obtained from GA, PSO and DE in all case studies, further demonstrating the capability of our framework to produce a wide range of optimal solutions with high diversity across different case studies.

This research demonstrates that Rao-2 not only improves solution quality when generating Pareto fronts but also achieves better results with fewer function evaluations compared to GA, PSO and DE. The algorithm's efficiency makes it particularly well-suited for optimizing time, cost and safety risks in large-scale construction projects, which in turn positions Rao-2 as a better choice for such projects by producing superior results compared to other algorithms. By providing high-quality solutions with reduced computational demands, Rao-2 offers a faster and more resource-efficient tool for decision-making, contributing to advancements in both the theory and practice of construction project management.

The aim of this study is to analyze the gastronomy festivals in Türkiye within the scope of the United Nations sustainable development goals.

In line with this purpose, a systematic review approach, which is a qualitative research method, was adopted as the method of the study. In the study, the data was collected with document analysis technique by accessing secondary sources. Systematic literature review was used to analyze the data.

When the gastronomy-themed festivals in Türkiye are analyzed, it is seen that 23 of them are in line with at least one of the United Nations sustainable development goals. The number of festivals organized in accordance with more than one of these goals is 18. The number of festivals organized in accordance with at least one goal is 5. The fact that only 23 of the 351 festivals in the research universe are organized in accordance with the United Nations sustainable development goals reveals that festivals are insufficient in terms of sustainability.

This study adopts theoretical approaches such as the experience economy, as it provides unforgettable consumption experiences for both producers and consumers participating in gastronomy festivals, and stakeholder theory, as festivals involve many stakeholders. The study also presents practical approaches, such as supporting local development, which is one of the primary objectives of festivals.

This study has revealed the sustainability status of gastronomy festivals in Türkiye which have been taken into consideration more frequently in recent years. It may also contribute to the literature to examine the organized gastronomy festivals within the scope of the UN sustainable development goals.

This study aims to examine the outcome of an online project to inform preservice English language teachers regarding the United Nations’ Sustainable Development Goals (SDGs).

A qualitative research method was used to understand participants’ overall knowledge. In total, 30 preservice teachers were selected from a larger pool after considering their grade point averages, sex, university affiliations and geographical backgrounds to ensure a balanced distribution and diversity. Qualitative data were collected through written productions, video recordings and a postproject survey.

Findings revealed that preservice teachers deepened their understanding of SDGs and adopted a positive attitude toward SDGs while increasing their pedagogical awareness and knowledge of teaching English in response to SDGs. They also regarded literary texts as a valuable resource for teaching SDGs.

This study contributes to the literature by demonstrating that literary works are valuable for educating preservice teachers on integrating SDGs. A detailed overview of the project and its outcomes can guide practitioners and teacher educators in integrating SDGs into their education programs and English language teaching.

Green destinations are places that are important for the sustainable realization of tourism. In addition to the design of these destinations, the management also emerges as an issue that needs to be emphasized. As a matter of fact, stakeholders and their relations with each other and other issues are an important element in the management of green destinations. In this context, in the study, issues such as management of green destinations, stakeholders, relations between stakeholders, education and green destination management in Türkiye are discussed. Finally, some suggestions have been presented within the framework of the topics discussed.

This chapter aims to highlight practices that ensure a livable climate and support the creation of a greener and more sustainable environment for community-based tourism in the case of Turkey. Green tourism needs to be improved and enhanced integrally from the perspective of tourism stakeholders, including tour operators, travel agencies, hotels, guests, and the host community. Turkey is the first country in the world to apply the green tourism certification system. It is a system very similar to the safe certificate system applied in tourism facilities. In Turkey, 4–5 star hotels are obliged to switch to this system. Community-based tourism is an alternative tourism approach that meets the needs and wishes of the host people, provides a more sustainable economy compared to other economic activities, and does not harm local culture and traditions. Global climate change and tourism are in a relationship with each other, and this relationship is even more evident for nature-based tourism types. Climate, natural environment, and personal security are seen as three main factors in the selection of a tourism center, and it is predicted by the Intergovernmental Panel on Climate Change that global climate change will have significant effects on these factors at the regional level. The United Nations World Tourism Organization accepts that the tourism industry should develop its potential to adapt to global warming, considering that the tourism industry is an economic sector that is open to the direct and indirect effects of climate change and is dependent on climate.

Migration is on the rise due to globalization and human mobility. This has led to increased impacts that have affected many industries, including the construction industry. A large number of migrants are employed in the construction sector, and employers are challenged to make sure all employees are properly integrated to meet the demands needed for construction projects. This article addresses key differences between migrant and native workers to help hiring departments in the construction industry analyse workers' attitudes based on cultural and motivational factors to have the workforce they need to succeed.

The research used both quantitative and qualitative surveys. A two-part questionnaire, designed through a comprehensive literature review, was carried out to identify key differences between native and migrant workers. The data were obtained and then analysed using different statistical approaches, including factor analysis protocol, factor structure model, reliability analysis, relative importance index and nonparametric test analysis. A semi-structured interview was then conducted to discuss all the findings.

The study indicated that migrant workers, compared to natives, tend to give more importance to their working environment, particularly accommodation, work safety and relations with teammates. Also, migrants typically take a socialistic approach instead of an individual approach while at work and reveal an extensive range of behaviours based on a sense of belonging. It might be more important for migrants to have a place in society, to have a settled life and to be integrated into an established order than to improve their rights and benefits. On the other hand, the study argued that native workers tend to prioritize their benefits at work, such as regular payments for overtime and insurance premiums. Their behaviours might carry a more neutral and individual attitude as well as specific cultural traces.

The study is limited to a sample of participants in the Turkish construction sector. Further research based on more cultural models and motivational factors with a larger group of respondents from different countries could offer better results. The results of the study might not apply to a broad context due to many other factors that affect worker behaviours, such as geography, cultural structures and working conditions. Despite these drawbacks, the present paper may help employers and other stakeholders understand the best way to incorporate migrants into the construction industry.

This research is very important for the construction industry in various countries that are currently employing thousands of migrants. Being able to address the key differences between migrants and native workers based on cultural and motivational factors might help with engagement and create a level of harmony in the field for greater productivity.

Despite the quantity of collaborations, the vocational network of the housing production in Ankara during its first five years (1923–1928) remains dispersed. The aim of this study is to identify all the actors of housing production and their collaborations which shaped Ankara's urban development as the new capital city.

The study engages with the literature and archival documents to identify the actors of the housing production, i.e. architects, master-builders, public institutions, private companies, contractors and entrepreneurs, and their resultant vocational network in the housing production in Ankara during 1923–1928.

Due to different agendas, such as speculation, financial interests or patriotism, the construction industry in Ankara had become an arena where many paths intersected, forming an intertwined vocational network. The profession of contractor became popular, and local architects, engineers and even individuals of various other professions began to work as mediators for foreign companies and public institutions, which required support especially in large-scale projects.

The dispersed information revealed that the actors of the housing production remained mostly anonymous, or only the famous architects were commemorated; however, others could be found within the lines of the established literature on Ankara and/or in archival documents. This research not only focuses on “salient” actors but also highlights the “silent” actors of the housing production and prepares charts to clarify the vocational network in Ankara during its first five years to contribute to the future studies on Ankara and its housing.

This study aimed to explore the adaptations and perspectives of hotel managers regarding green and smart hotel technologies within the context of sustainability.

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.

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.

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.

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.

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.

The study was designed to investigate the moderating role of employee motivation as a mediator of psychological ownership in the relationship between nurses’ perception of participatory leadership and their organizational learning behaviors.

The study included 476 nurses working in a training and research hospital in the east of Turkey. This study, prepared in accordance with the Strobe checklist, was designed as a cross-sectional descriptive study. Data were collected using a demographic information form, a participative leadership scale, an organizational learning scale, a psychological ownership scale and a motivation scale. Correlation analyses and mediator model tests were performed to examine the relationship between these variables.

As a result, it was found that nurses’ perceptions of participative leadership positively and significantly affected organizational learning (r = 0.74; p < 0.01), participative leadership positively affected psychological ownership (r = 0.29; p < 0.01) and nurses’ psychological ownership positively and significantly affected organizational learning (r = 0.41; p < 0.01). In addition, it was found that nurses’ psychological ownership had a mediating role in the effect of participatory leadership perceptions on organizational learning (CI [0.030, 0.089]) and nurse motivation had a moderating role between psychological ownership and organizational learning (β = 0.168, 95% CI [0.064, 0.271]).

The study’s findings have practical implications for the Turkish health system and healthcare administrators. Administrators can significantly enhance organizational learning by implementing participative leadership training and fostering a sense of ownership among nurses. Empowering nurses to take charge of their learning and emphasizing the role of motivation can further drive organizational growth.

The purpose of this study is to assess the attitudes of individuals living in Belgium and in Emirdag in regard to patient rights and the effect of cultural differences in developing the attitude. This study measures the attitudes of two groups of people living in different geographies, “individuals living in Emirdag and Individuals emigrated from Emirdag to Belgium,” and yet having the same ethnic origin, common social and cultural capital.

Implementing quantitative research, the data for the current study was obtained from a total of 1,043 participants, who were administered the Likert type “Patient Rights Attitude Scale” along with demographic questionnaire.

The total score mean of the scale is 126.09 ± 15.21 in the Emirdag group, whereas in the Belgian group, it is 129.78 ± 13.356. While the attitude with the highest mean score about patient rights in both groups observed under “the right to seek medical attention” and “the right to consent in medical and drug researches” items and thusthese items are considered as a common denominator, the two groups differed in the scale items that received the lowest average.

It is important to determine the effects of attitudes toward patient rights and cultural differences on the development of attitudes, to determine the problems in the delivery of health services and health service procurement.

The structures that direct the choices and decisions of individuals in critical subjects such as organ transplantation and euthanasia, and thus having different practices in the doctrine, can be affected by individuals and even society’s rules, beliefs and values. It was concluded that immigrant participants’ dominating culture and related beliefs, rules and values play a role in the making of decision and choice.
