In today’s dynamic and highly uncertain environment, organizations, particularly in the aviation sector, face increasing challenges that demand resilient, flexible, and data-driven change management decisions. Responding to the growing need for structured approaches to managing complex uncertainties—geopolitical tensions, economic volatility, social shifts, rapid technological advancements, environmental pressures and regulatory changes—this research proposes a theoretical change management model for aviation service providers, such as airports. Integrating three analytical approaches, the model offers a robust, multi-method approach for supporting sustainable transformation under uncertainty. Normative analysis using Bayesian decision theory identifies influential external environmental factors, capturing probabilistic relationships, and revealing causal links under uncertainty. Prescriptive planning through scenario theory explores alternative future pathways and helps to identify possible predictions, offer descriptive evaluation employing fuzzy comprehensive evaluation, and assess decision quality under vagueness and complexity. The proposed four-stage model—observation, analysis, evaluation, and response—offers a methodology for continuous external environment monitoring, scenario development, and data-driven, proactive change management decision-making, including the impact assessment of change and development. The proposed model contributes to the theoretical advancement of the change management research area under uncertainty and offers practical guidance for aviation organizations (airports) facing a volatile external environment. This framework strengthens aviation organizations’ ability to anticipate, evaluate, and adapt to multifaceted external changes, supporting operational flexibility and adaptability and contributing to the sustainable development of aviation services. Supporting aviation organizations with tools to proactively manage systemic uncertainty, this research directly supports the integration of sustainability principles, such as resilience and adaptability, for long-term value creation through change management decision-making.

Background/Objectives: Prehabilitation is a multimodal intervention introduced in preparation for various surgical procedures. The most effective treatment for obesity is bariatric surgery. Physiotherapy during prehabilitation for bariatric surgery may be an effective method of functional capacity improvement. We aimed to evaluate the impact of an individual outpatient 12-week, exercise-based physiotherapy program featuring prehabilitation on functional status, exercise tolerance, everyday mobility, and fatigue among patients qualified for bariatric surgery. Methods: The completion of an individual outpatient 12-week, exercise-based physiotherapy program during prehabilitation was an inclusion criterion for the study group. Participants included in the study and control groups were assessed twice, after enrollment into the prehabilitation program (the first assessment) and after prehabilitation but before surgery (the second assessment). Both assessments involved functional tests (a six-minute walking test [6MWT], a timed up and go test [TUG], a chest mobility test, anthropometric measures, a mobility index [Barthel], and a modified Borg scale). The collected anthropometric data and values from the 6MWT were used to create original linear models. This study followed STROBE recommendations. Results: The study group and control group did not differ statistically in terms of their anthropometric data. Statistically significant results were obtained between the first and second assessments in both groups in terms of body weight and waist circumference. However, only the study group showed improved results in the TUG test (p = 0.0001) and distance in the 6MWT (p = 0.0005). The study group presented with the normalization of blood pressure (BP) after exertion in the second assessment (systolic BP p = 0.0204; diastolic BP p = 0.0377), and the 6MWT results were close to the norms. According to the original linear model used to predict performance in the 6MWT, the primary modifiable determinant of exercise tolerance was the participant’s weight, while gender served as a non-modifiable determinant. Conclusions: Exercise-based physiotherapy in prehabilitation was associated with improved functional capacity in patients preparing for bariatric surgery, contributing to the improvement in 6MWT results in relation to the norms as well as exercise tolerance. Body weight may be an independent factor determining distance in the 6MWT for patients undergoing prehabilitation for bariatric surgery. Full article

Social marketing modifies individual behavior to achieve specific outcomes, mitigating environmental pressures. While proven effective in influencing consumer behavior, empirical studies on its impact on the tourism sector remain limited. This study examines how various social marketing channels influence tourists’ consumption decisions and contributes to achieving SDGs 11 and 12 by reviewing the existing methods of disseminating social marketing content. A conceptual model grounded in theory was developed and empirically tested. In particular, it focuses on the establishment of direct and indirect multi-route effects between social marketing and consumer behavior and introduces different influencing factors. Given the scarcity of research on collective culture, quantitative methods were employed, with data collected through questionnaires in mainland China. Results indicate that social marketing media significantly influence tourist behavior, with three mediators—subjective norms, personal values, and communication channels—playing varying roles across media types (events, public relations, and traditional media). Subjective norms, values, and communication channels act as mediators. This study bridges social marketing, tourist behavior, and SDG attainment, offering novel insights and practical implications for tourism practitioners. Full article

This article explores the role of the European Union (EU) as a normative gender actor promoting women’s participation in STEM (Science, Technology, Engineering, and Mathematics) within the Eastern Partnership (EaP) region. In a context marked by global inequality and overlapping international efforts, this paper assesses the extent to which EU-driven Europeanisation influences national gender policies in non-EU states. Using a postfunctionalist lens, this research draws on a qualitative analysis of EU-funded programmes, strategic documents, and a detailed case study encompassing Armenia, Georgia, Moldova, Ukraine, Belarus, and Azerbaijan. This study highlights both the opportunities created by EU initiatives such as Horizon Europe, Erasmus+, and regional programmes like EU4Digital and the challenges presented by political resistance, institutional inertia, and socio-cultural norms. The findings reveal that although EU interventions have fostered significant progress, structural barriers and limited national commitment hinder the long-term sustainability of gender equality in STEM. Moreover, the withdrawal of other global actors increases pressure on the EU to maintain leadership in this area. This paper concludes that without stronger national alignment and global cooperation, EU gender policies risk becoming symbolic rather than transformative. Full article

Tourism development in coastal zones is often guided by marketing strategies focused on promotion, without real integration with the ecological, identity, and planning challenges facing these territories. This disconnection compromises environmental resilience, dilutes local cultural identity, and hinders adaptive governance in contexts of increasing tourism pressure and climate change. In response to this problem, the article presents the concept of Blue Marketing, a place-based, sustainability-oriented approach designed to guide communication, product development, and governance in marine and coastal destinations. Drawing on socio-environmental marketing and inspired by Integrated Coastal Zone Management (ICZM), the study proposes a Blue Marketing Decalogue (BMD), structured into three thematic blocks: (1) Ecosystem-focused sustainability, (2) cultural identity and territorial uniqueness, and (3) strategic planning and adaptive governance. Methodologically, the decalogue is empirically grounded in a territorial diagnosis of the Barbate–Vejer coastal corridor (Cádiz, Spain), developed through Geographic Information Systems (GIS), local planning documents, and field observations. This case study provides a detailed analysis of ecological vulnerabilities, cultural resources, and tourism dynamics, offering strategic insights transferable to other coastal contexts. The BMD incorporates both strategic and normative instruments that support the design of responsible tourism communication strategies, aligned with environmental preservation, community identity, and long-term planning. This contribution enriches current debates on sustainable tourism governance and provides practical tools for coastal destinations aiming to balance competitiveness with ecological responsibility. Ultimately, Blue Marketing is proposed as a vector for transformation, capable of reconnecting tourism promotion with the sustainability challenges and opportunities of coastal regions. Full article

The ‘ring by spring’ (RBS) phenomenon entails pressures for college seniors on Christian campuses to become engaged by the spring semester of their senior year. These marital pressures often run counter to national trends in the USA as the median age at first marriage continues to climb. The social clock theory suggests that society places a normative timetable on major events such as marriage. But the social clock may not happen the same way for all people, and influences on Christian campus may represent deviations from most normative social clocks. This study investigated RBS awareness, experiences, pressures, and perceptions, along with assessing for differences in gender and religiosity across multiple universities, both Christian and not, across two different states. Results show wide awareness and experience with RBS at many universities along with some notable differences by gender and religiosity. Implications are provided for researchers and practitioners based on study findings. Full article

As Artificial Intelligence systems increasingly surpass or replace traditional human roles, institutions founded on beliefs in human cognitive superiority, moral authority, and procedural oversight encounter a more profound challenge than mere disruption: expiration. This paper posits that, instead of being outperformed, many legacy institutions are becoming epistemically misaligned with the realities of AI-driven environments. To clarify this change, the paper presents the Expiration Theory. This conceptual model interprets institutional collapse not as a market failure but as the erosion of fundamental assumptions amid technological shifts. In addition, the paper introduces the AI Pressure Clock, a diagnostic tool that categorizes institutions based on their vulnerability to AI disruption and their capacity to adapt to it. Through an analysis across various sectors, including law, healthcare, education, finance, and the creative industries, the paper illustrates how specific systems are nearing functional obsolescence while others are actively restructuring their foundational norms. As a conceptual study, the paper concludes by highlighting the theoretical, policy, and leadership ramifications, asserting that institutional survival in the age of AI relies not solely on digital capabilities but also on the capacity to redefine the core principles of legitimacy, authority, and decision-making.

Urban transportation systems face increasing pressure to reduce car dependency and greenhouse gas emissions while supporting sustainable growth. This study addresses the lack of integrated modeling approaches that capture both spatial and temporal dynamics in transport planning. It develops a novel framework combining System Dynamics (SD) and Geographic Information Systems (GIS) to assess the sustainability of Transit-Oriented Development (TOD) strategies and parking policies in two brownfield redevelopment sites in Montreal. The framework embeds spatial metrics, such as proximity to transit, parking availability, and active transportation infrastructure into dynamic feedback loops. Using scenario analysis, the study compares a baseline reflecting current norms with an intervention scenario emphasizing higher density near transit, reduced parking ratios, and improved walkability and bike infrastructure. The results suggest that aligning TOD principles with targeted parking limits and investments in active mobility can substantially reduce car ownership and emissions. While primarily conceptual, the model provides a foundation for location-sensitive, feedback-driven planning tools that support sustainable urban mobility. Full article

With the rapid development of urban rail transit, the impact of shield tunneling on existing pipelines is increasing. To protect pipeline safety, this research focuses on the complex pipelines in the Shaluo shield tunneling section, utilizing FLAC3D numerical simulation software to investigate the deformation characteristics of cast iron pipelines during shield construction. Additionally, it quantifies the influence of pipeline materials on deformation and establishes the pipeline safety risk grading system. Safety assessment of pipelines based on the research. The research indicates that (1) The deformation difference between the tops of the pressure and pressureless pipeline is less than 1 mm, suggesting that pipeline deformation is minimally influenced by pressure. The deformation is the largest at the entrance and gradually decreases along the direction of excavation, indicating that the deformation has an obvious hysteresis effect. (2) The threefold variation in maximum deformation among pipelines of different materials during shield tunneling indicates the high sensitivity of pipeline material properties to shield construction processes. (3) By analyzing and discussing the literature and local norms, the deformation value of the pipeline is taken as the evaluation index. And the pipeline assessment system is established. (4) Cast iron pipelines at the start of the shield have the highest safety, and concrete pipelines at the beginning of the shield are the lowest. Full article

This study critically reflects on Myanmar’s readiness and potential to transition from internal combustion engine (ICE) vehicles to electric vehicles (EVs) amidst escalating climate pressures, energy insecurity, and regional technological shifts. It aims to advocate a systemic and inclusive EV strategy rooted in environmental, economic, and governance imperatives. Drawing on an extensive review of scholarly literature, policy documents, and regional best practices, this study synthesizes evidence to frame a normative argument for accelerating the adoption of EVs in Myanmar. It combines the environmental, infrastructural, and political–economic perspectives to support its position. Myanmar’s EV transition is not merely a technological leap, but a structural transformation intertwined with energy equity, public health, and geopolitical positioning. While significant barriers, such as grid unreliability, policy inconsistency, and socioeconomic disparities, persist, coordinated national efforts and regional cooperation can unlock transformative opportunities. Policy clarity, grid modernization, public engagement, and international partnerships are essential enablers. This study offers a timely and region-specific perspective on the EV debate, highlighting Myanmar’s unique vulnerabilities and latent advantages. It presents a value-based call for inclusive, future-oriented policymaking that aligns Myanmar’s mobility system with its sustainability and development goals. Full article

Mediterranean island cities face unique challenges in implementing smart city initiatives due to fragmented governance structures, seasonal economic pressures, and evolving societal expectations. This study investigates how strategic aspirations and public discourse shape the feasibility of smart city policies in insular contexts. Specifically, it combines SOAR (Strengths, Opportunities, Aspirations, Results) analysis with the Overton Window framework to examine both the strategic capacities and normative acceptability of technological interventions. The Overton Window, a model originally developed in political theory, is applied here to evaluate how public and policy acceptance of smart technologies, ranging from digital governance systems to AI-based mobility, varies across different islands. While this study draws on cross-case comparisons of multiple Mediterranean island contexts, the primary data were collected in Athens, Greece, through surveys and focus groups with citizens and stakeholders. The findings reveal disparities in institutional maturity, stakeholder coordination, and levels of citizen support. This study concludes that successful smart city transformation requires both strategic coherence and alignment with evolving public values. It proposes the ‘Ecopolis’ model as a conceptual planning framework that integrates sustainability, citizen participation, and data-driven governance in tourism-dependent island settings.

African cities are experiencing rapid, unregulated growth, characterized by high land pressure and growing demand for housing and urban infrastructure. New arrivals often settle in vulnerable areas (wetlands, hills, flood) where land is cheaper and unregulated by public authorities. This type of settlement is accompanied by numerous land conflicts, exacerbated by the coexistence of formal and customary land tenure systems, which struggle to harmonize. In this context, public land regulation policies often remain centralized and ill-adapted, revealing their limitations in ensuring equitable and sustainable management of urban land. Faced with this gap, our systematic study explores the socio-environmental dynamics of this normative pluralism in land governance within Cameroonian cities. Our findings highlight the tensions and opportunities of this complex coexistence, which vary significantly according to city size (small, medium, and large), the colonial heritage (Francophone and Anglophone), and the dominant legal framework (civil law and common law). The analysis highlights the need to take into account historical, linguistic, and politico-administrative roots, which profoundly influence local forms of the institutionalization of normative pluralism and the associated socio-environmental vulnerabilities. This normative plurality underlines the importance of a hybrid system of land governance capable of integrating local specificities while ensuring land security for all. Future research will include comparisons with other African countries in order to understand transferable mechanisms for better land governance. Full article

A palm oil company based in Bangka is actively expanding its operations in the palm oil processing industry. The company specializes in producing crude palm oil (CPO) and palm kernel, with its production process encompassing five key stages: weighing, sterilization, threshing, pressing, and clarification. Oil loss, especially at the pressing station, is one of the company’s biggest problems. Nuts, fibers, empty bunches, and effluent are some of the sources of oil loss in CPO production. Since extreme losses that exceed set norms can cause serious inefficiencies and financial repercussions, it is imperative that the organization identifies and mitigates the underlying causes of oil loss. One option that the business could use is the fault tree analysis (FTA) method, which offers a methodical way to pinpoint the root causes of production inefficiencies to solve this problem. According to current assessments, empty bunches caused the largest average oil loss over a one-month period, with a loss rate of 0.11%. Oil loss at the pressing station is caused by a number of factors, such as inadequate maintenance practices, non-compliance with established work procedures, suboptimal ripeness levels of harvested palm fruit, and operator neglect in maintaining optimal machine pressure in accordance with company standards. To reduce oil loss in the production process and increase efficiency, these concerns need to be addressed. Full article

Questioning motherhood as a social mandate has been one of the main objectives of feminism. Motherhood has traditionally been linked to the idea of femininity and the reproductive function, which has led to women being thought of as “compulsory mothers”. However, this idea is currently changing, despite the fact that judgment is exercised on non-mothers. This research is part of a cross-sectional descriptive study, whose objective is to analyze the barriers and incentives to childbearing in the female population. A questionnaire was designed and administered to a representative sample of 318 women who were selected for our analysis, with a confidence level of 95% and a margin of error of 5%. Results: Economic motives correlate positively with other variables, as well as work motives, the couple’s decision to not want to have children, and not having a stable partner, which suggests that these women have different motives for choosing not to have children. The main conclusions are that social and family pressures appear to have a limited impact on the decision not to have children, suggesting a change in social norms and expectations about the role of women in society, as women continue to gain autonomy and control over their reproductive decisions.

The cage tilapia farming boom in Kenya’s Lake Victoria region underscores its role in food security and economic growth. Success depends on understanding producer and consumer behaviors within the value chain. Using the Theory of Planned Behavior (TPB), this study examines how attitudes (evaluations of farming/consumption), subjective norms (social pressures), perceived behavioral control (confidence in actions), environmental awareness, and moral obligation shape decisions. A survey of 66 producers and 169 consumers, analyzed via structural equation modeling (SEM), reveals key drivers. Producers are driven by positive attitudes toward profitability, technical feasibility, and sustainability, reinforced by community norms and resource access, promoting sustainable practices. Consumers prioritize health, affordability, and accessibility of cage-farmed tilapia, with environmental and ethical factors less influential. These findings highlight opportunities for targeted interventions to enhance production, boost demand, and ensure sustainable aquaculture. Full article
