    SDG-Oriented Compulsory Courses in Higher Education: An Exploratory Case from Turkey
    (Emerald Group Publishing Ltd, 2026) Gover, Ibrahim Hakan; Ayten, Asim Mustafa
    Purpose This study aims to examine students' perceptions of a set of compulsory Sustainable Development Goal (SDG)-oriented courses implemented across undergraduate programmes at a newly-established Turkish state university. Rather than evaluating individual courses, the study explores how a compulsory, SDG-framed curricular approach is associated with students' reported sustainability awareness, civic orientation and social engagement within a specific institutional context.Design/methodology/approach Data were collected from 325 undergraduate students enrolled in four compulsory SDG-oriented courses during the 2024-2025 academic year using a non-probability convenience sampling approach. A 19-item structured survey was administered to capture students' self-reported awareness and attitudes related to sustainability and social responsibility. Descriptive and inferential analyses (including t-tests and ANOVA after verifying normality assumptions) were conducted using SPSS and R.Findings The findings, derived from a composite impact scale, suggest that participation in SDG-oriented compulsory courses is associated with higher levels of sustainability awareness and positive orientations towards civic responsibility and social engagement. Differences were observed across demographic groups, with female students and those reporting prior familiarity with sustainability concepts indicating stronger perceived impacts. Given the exploratory design and reliance on self-reported data, the results should be interpreted as indicative rather than conclusive.Research limitations/implications The study is limited by its cross-sectional design, convenience sampling and reliance on self-reported perceptual data, which restricts causal interpretation and generalisability. The findings capture the initial, formative stages of learning rather than long-term transformation. As the data were collected from students enrolled in the earlier and intermediate stages of a set of compulsory SDG-based courses, the findings do not capture longer-term educational effects associated with the full curricular sequence. Future research employing longitudinal and comparative designs could provide deeper insight into how SDG-oriented curricular approaches develop over time and across institutional contexts.Practical implications The study provides empirical insight into how compulsory, SDG-oriented courses may contribute to students' sustainability-related awareness and civic orientations within higher education curricula. For curriculum developers and policymakers, the findings highlight both the potential and the limitations of using dedicated courses as one possible approach to embedding education for sustainable development.Social implications By foregrounding students' perspectives, the study contributes to ongoing discussions on the role of higher education in supporting sustainability-oriented values and social responsibility.Originality/value This study contributes exploratory, context-specific evidence on students' perceptions of SDG-oriented compulsory courses in Turkish higher education, offering a cautious empirical basis for further discussion and research on education for sustainable development at the institutional level.

    Effects of Alkanolamines on Calcium Sulfoaluminate Belite Cement Hydration and Fresh Properties
    (Emerald Group Publishing Ltd, 2026) Uzal, Burak; Wilkinson, Angus P.; Qoku, Elsa; Nguyen, Tu-Nam; Kurtis, Kimberly E.
    Calcium sulfoaluminate belite cements have found widespread use in specialised applications but have not been applied broadly due to rapid setting times. Conventional set retarders such as citric and tartaric acids modify hydration kinetics, introducing ancillary effects that alkanolamines may avoid. This study examined the effects of three alkanolamines, triisopropanolamine (), triethanolamine () and diisopropanolamine (), on early hydration at 0.02% dosage; was also tested across a broader dosage range. Reaction kinetics and phase evolution were examined in pastes by calorimetry, thermogravimetric analysis () and in situ quantitative X-ray diffraction () for 72 h of hydration, along with setting time and amplitude-sweep rheometry. Calorimetry showed that and delayed and reduced the main cement hydration peak, while all alkanolamines delayed and enhanced the shoulder and secondary hydration peaks. In situ and suggested that alkanolamines decrease ettringite and alumina gel formation by 24 h and may lead to poorly crystallised ettringite that cannot be quantified by . Alkanolamine-containing samples demonstrated increased storage and loss moduli and extended linear viscoelastic ranges. A consistent grouping of similar behaviour emerged: control/TIPA versus TEA/DIPA, suggesting distinct mechanisms. Finally, among the alkanolamines, was the most effective, increasing the setting time by 18 min.

    An Alternative Spatial Reflex to the Global Nomadic Lifestyle Experience: Escapecore
    (Emerald Group Publishing Ltd, 2026) Cam, Elif; Alkan Bala, Havva
    Purpose - This study aims to analyze global nomadism, transformed by the deepening crises of the Anthropocene, as a contemporary spatial reflex and to propose the conceptual model of Escapecore, which redefines belonging through movement, adaptability and self-centeredness in a context where fixed geographies lose their validity. Design/methodology/approach - The study adopts a qualitative, holistic and visual - analytical approach to interpret spatial crises in the Anthropocene and to formulate Escapecore as an alternative spatial reflex to global nomadic lifestyles. The method involves concept coding, thematic clustering into a layered flow from the Anthropocene to Escapecore, and visual - spatial mapping through diagrams expressing its ontological coordinates. Validity is grounded in the coherence and contextual adaptability of the conceptual network. Findings - Spatial crises in the Anthropocene trigger individual housing reflexes, with Escapecore emerging as an alternative spatial behavior amid the collapse of permanence and the redefinition of belonging. Visual and conceptual analyses show a tendency to construct temporary yet meaningful places across digital and physical realms, indicating that nomadism has evolved into a form of existence based not only on mobility but also on emotional and cognitive flexibility. Originality/value - The article proposes a conceptual model that rethinks individual existence and spatial belonging in the Anthropocene through Escapecore. By linking Anthropocene-driven crises to new practices of movement-based belonging, the study opens a pathway for future design research and spatial prototyping grounded in resilience and multi-scalar adaptability.

    Resilience and Market Diversification in Sustainable Tourism: Evidence from International Arrivals to Türkiye (2012-2025)
    (Emerald Group Publishing Ltd, 2026-02-02) Atay, Mehmet Tarik; Ciuffreda, Raffaela; Coskun, Safa Bozkurt
    PurposeThis study analyzes the possible connections between resilience and market diversification of inbound tourism to T & uuml;rkiye from 2012 to 2025. The aim is to assess the reaction of international arrivals to global fluctuations, such as the COVID-19 pandemic era, and to examine the structural linkage to primary source markets within the concept of sustainable tourism management.Design/methodology/approachThe research uses annual country-specific data related to international arrivals. We used time-series analysis to uncover long-term behaviors and the consequences of crises. The research also used Shannon entropy and the Herfindahl-Hirschman Index to look at market concentration and diversity. A comparative analysis of the primary source countries indicates variations in recovery trajectories and resilience in the concept of sustainable tourism management.FindingsThe results show that T & uuml;rkiye's inbound tourism grew steadily until 2019, decreased severely during the pandemic and then bounced back strongly from 2022 to 2024. Market diversity has improved over time, but dependence on Germany and the Russian Federation tourists' activities is still high. Although the UK was more stable, and regional markets like Bulgaria and Iran were more unstable, their positive effect on achieving the sustainable tourism goal is still weak.Research limitations/implicationsThe study is constrained by the partial coverage of 2025 data and the lack of direct indicators for environmental or social sustainability. Future research may combine these dimensions and their data to construct a more thorough and detailed evaluation for better understanding of the sustainable tourism context.Practical implicationsThe results show that for tourism in T & uuml;rkiye to be sustainable, it needs to have more diverse source markets, be better prepared for global or local crises and have plans for managing capacity, especially tourism management and seasonality. These insights can help government policymakers and local destination management bodies make long-term sustainability stronger.Social implicationsHighly concentrated tourism markets may cause revenue and employment volatility when principal source countries experience a downturn. Advocating for diversity in terms of various source markets for inbound tourism activities enhances tourism-related economic and social resilience and community welfare in terms of stable income flow and fosters inclusive growth throughout the local and national community in accordance with sustainable tourism objectives.Originality/valueThis study directly connects resilience and diversity to the management of sustainable tourism in a new destination. By integrating long-term real case data with related, respected and detailed market structure metrics, it offers novel insights into how destinations might improve their competitiveness, decreased vulnerabilities in crisis time periods and improve the sustainability of the tourism sector.

    Sustainable Conservation Through the Interrelations Between Rural Architecture and Life: The Case of Çomakdağ
    (Emerald Group Publishing Ltd, 2025-06-24) Kurtulus, Vacide Betul; Guchan, Neriman Sahin; Şahin Güçhan, Neriman
    PurposeThe paper aims to propose a new approach to the sustainable conservation of rural heritage with the aim of understanding the relations between built environment and society. In the document "Concerning Rural Landscapes as Heritage" by ICOMOS-IFLA, it is argued that there is an interaction between daily life practices and the physical environment for production and cultural activities (ICOMOS, 2017). The main objective of the study is to underline the importance and necessity for this interaction continue for the sustainable conservation of rural areas.Design/methodology/approachThis paper investigates the relationship between the built environment and daily practices in Turkey's & Ccedil;omakdag Region, known for its significant rural architecture and enduring traditions. Through on-site investigation, the study explores the evolution of these relationships across various scales, including buildings, settlements and the region itself. This multi-scale approach aims to identify remaining cultural values and user needs.FindingsTraditional ways of life have undergone a transformation, impacting the interactions between inhabitants and their natural, agricultural and architectural spaces. The primary drivers of these changes are shifts in income sources, technological advancements and infrastructural developments within the settlements. While maintaining a connection between the built environment and daily life practices remains essential, contemporary living conditions and altered routines present challenges to this continuity.Originality/valueThis study builds on previous research on the & Ccedil;omakdag Region. Batur (2010) explored the region's architectural features, including colors and ornamentation. Kurtulus and G & uuml;& ccedil;han (2020) focused on Kizilaga & ccedil; village, examining typical house characteristics. This research offers a new perspective on rural heritage preservation. It emphasizes the importance of maintaining the interrelationship between daily life and the built environment across various scales for sustainable conservation.

    Surprise Me With Your Ads! The Impacts of Guerrilla Marketing in Social Media on Brand Image
    (Emerald Group Publishing Ltd, 2018-11-08) Gokerik, Mehmet; Gurbuz, Ahmet; Erkan, Ismail; Mogaji, Emmanuel; Sap, Serap
    Purpose - The advent of social media brought a new perspective for guerrilla marketing since it allows ads to reach more people through the internet. The purpose of this paper is to investigate the influence of guerrilla marketing in social media on brand image. Design/methodology/approach - A conceptual model was developed based on the information acceptance model (IACM). The research model was validated through structural equation modelling based on the surveys of 385 university students. Findings - The results support the proposed model and confirm that guerrilla marketing in social media has a positive effect on both functional and symbolic brand image. Research limitations/implications - This study was conducted with university students. This sample was deemed appropriate since the study had to be conducted with people who use social media. However, although the age group of university students constitutes the majority of social media users, they may not fully represent the whole population. Also, this study showed four guerrilla marketing examples to participants before they commenced filling in the questionnaire. Although the authors selected the most generic guerrilla advertisements during the pilot tests and eliminated the ones which were difficult to understand, this can still be considered as limitations of the study. Practical implications - This study has both theoretical and managerial implications. First, most of the guerrilla marketing studies focus on consumers and neglect possible impacts on brands. In order to fulfil this gap in the literature, this study investigates the influence of guerrilla marketing in brand image. Besides, this study contributes to IACM by expanding its scope through testing its determinants on "brand image". It proves that IACM is valid for use in different contexts. On the managerial side, this study provides marketers with a frame of reference to understand the information adoption process of guerrilla marketing on social media. Originality/value - Current studies regarding the influence of guerrilla marketing mostly focus on consumers, where the possible impacts on brands have been relatively neglected. This study attempts to fill this gap by focussing on the brand image.

    Solution of Jamming Transition Problem Using Adomian Decomposition Method
    (Emerald Group Publishing Ltd, 2018-08-08) Senturk, Erman; Coskun, Safa Bozkurt; Atay, Mehmet Tarik
    Purpose The purpose of the study is to obtain an analytical approximate solution for jamming transition problem (JTP) using Adomian decomposition method (ADM). Design/methodology/approach In this study, the jamming transition is presented as a result of spontaneous deviations of headway and velocity that is caused by the acceleration/breaking rate to be higher than the critical value. Dissipative dynamics of traffic flow can be represented within the framework of the Lorenz scheme based on the car-following model in the one-lane highway. Through this paper, an analytical approximation for the solution is calculated via ADM that leads to a solution for headway deviation as a function of time. Findings A highly nonlinear differential equation having no exact solution due to JTP is considered and headway deviation is obtained implementing a number of different initial conditions. The results are discussed and compared with the available data in the literature and numerical solutions obtained from a built-in numerical function of the mathematical software used in the study. The advantage of using ADM for the problem is presented in the study and discussed on the basis of the results produced by the applied method. Originality/value This is the first study to apply ADM to JTP.

    Social Media Utilization of Tourists for Travel-Related Purposes
    (Emerald Group Publishing Ltd, 2015-07-13) Oz, Mustafa
    Purpose - The aim of this study is to determine social media use by consumers for travel-related purposes. Design/methodology/approach - A quantitative study was conducted after reviewing the related literature. The primary data were collected by means of an online questionnaire, and the results were analyzed using a statistical package program. Findings - The respondents use social media intensively both in their daily lives (> 96 per cent) and in travel-related activities (95 per cent). In addition to the detailed analyses of their usage, a model was developed to identify the factors behind social media use for travel-related purposes. Research limitations/implications - As a result of an online questionnaire method, only consumers having an Internet access could respond to the survey. Additionally, the sample was not random, and the respondents were selected only from Turkey. Consequently, the study may suffer from a generalization problem, especially for markets with major different cultural characteristics. Practical implications - The findings of the study may assist academics and practitioners to better understand social media and Web 2.0 technologies and their effects on consumers. Originality/value - One of the dominant trends affecting consumer behavior and tourism marketing in recent years is the use of social media. It is critical to understand such developments and their effects on consumer behavior that may impact on the distribution and accessibility of travel-related information.

    Investor Bias, Risk and Price Volatility
    (Emerald Group Publishing Ltd, 2022-11-29) Polat, Ali Yavuz
    PurposeThis study proposes a framework based on salience theory and shows that focusing on one type of risk (idiosyncratic or systemic) can explain overpricing of securities ex ante, and resales at low prices during crisis periods.Design/methodology/approachThe author consider an overlapping generations (OLG) model where each generation lives for two periods and there is no population growth. Agents (investors) start their lives with an endowment W > 0 and have mean-variance utility. They invest their endowment when young and consume when old. Each period, the young investors optimally choose their portfolio from different risky assets acquired from the old generation, all assumed to be in fixed supply.FindingsThe author show that investor salience bias can explain excess volatility of asset prices and the resulting fire-sales in periods of financial turmoil. A change in salience - from one component (idiosyncratic) to the other (systemic) - will generate excess volatility. Interestingly, higher risk aversion generally exacerbates the excess volatility of prices. Moreover, the model predicts that if a big systemic shock hits the financial system, due to salience bias the price of systemic assets falls sharply. This relates to the observed fire-sales of assets during the global financial crisis.Practical implicationsThe proposed model and results suggest that there may be a scope for intervention in financial markets during turbulences. In terms of ex ante policies the study suggests that investors and regulator should use better risk assessment technologies.Originality/valueThis is the first study constructing a tractable model based on the argument that investor salience may exacerbate the excess volatility of prices during financial downturns. The author relate salience to two types of risk; idiosyncratic and systemic and assume that investors' risk perception is biased towards the type of risk that is currently salient based on prior beliefs or past data. The author show that the diversification fallacy of the precrisis period, where seemingly safe assets were overpriced, can be explained by agents overweighing idiosyncratic risk and ignoring systemic risk.

    Business Model Adaptation as a Strategic Response to Crises: Navigating the COVID-19 Pandemic
    (Emerald Group Publishing Ltd, 2021-10-28) Chanyasak, Teerawut; Koseoglu, Mehmet Ali; King, Brian; Aladag, Omer Faruk
    Purpose This study aims to explore how hotels adapt their business models as a strategic response to crisis situations. It sheds light on the processes and methods of business model adaptation during severe crisis situations, such as the COVID-19 outbreak. Design/methodology/approach A single-case study was conducted. Data were collected from the owner/manager of a boutique hotel chain in Chiang Mai, Thailand through an extensive interviewing process. The authors also examined corporate documents. The authors then re-organized the material as a coherent narrative about how the company navigated the COVID-19 crisis. Findings The findings show that the hotels in the study adapted their business models by cutting costs through stopping non-essential operations, increasing non-room revenues and adding new revenue channels, bringing in cash from advance bookings, securing financial support from creditors, leveraging government support and training staff for the "new normal." Originality/value Few previous studies have focused on business model adaptation during the COVID-19 crisis. The investigation of this largely neglected area provides two main contributions. First, it extends the literature on crisis management in hospitality firms by examining business model adaptation patterns and processes during unprecedented crisis conditions. Second, it provides managerial insights and a business model adjustment framework to help practitioners in urban settings in their efforts toward recovery from the COVID crisis.
