Structural Equation Modeling (SEM) is a key framework for analyzing complex economic relationships involving latent variables, mediation effects, and endogeneity, yet the choice between frequentist and Bayesian estimation remains theoretically and practically contested, especially in settings with non-stationary data and small samples. This study provides a formal comparison of the two approaches by formulating SEM as a probabilistic graphical model and deriving the corresponding estimation procedures, identifiability conditions, and uncertainty measures. We examine asymptotic properties of frequentist estimators and posterior consistency in Bayesian SEM, with particular attention to integrated time-series SEM applications such as shadow economy estimation. The analysis shows that while both approaches converge under large-sample conditions, important differences arise in finite samples. Bayesian methods exhibit more stable point estimates through coherent uncertainty quantification, particularly when prior information regularizes an otherwise ill-conditioned likelihood. Under model misspecification, Bayesian posteriors concentrate around the pseudo-true parameter defined by the Kullback-Leibler projection, providing a probabilistic representation of misspecification uncertainty through posterior spread—an advantage over frequentist inference, which typically conditions on the maintained model as exact. These findings carry direct implications for empirical economic modeling under realistic data constraints. In settings where sample sizes are small, identification is weak, and model uncertainty is substantial, conditions that routinely characterize macroeconomic research, the choice of inferential framework is not a matter of philosophical preference but a determinant of whether policy-relevant conclusions can be credibly defended. Bayesian SEM offers a principled and transparent path forward in precisely these conditions. Full article

Workplace harassment of transgender employees remains pervasive and understudied. In this narrative review of 63 studies over the past 25 years, we summarize the literature on transgender workplace harassment. We focus on its prevalence and forms. Individual, organizational and cultural factors contribute to its occurrence; psychological and occupational outcomes; and strategies to reduce or prevent harassment. We find that harassment often extends beyond traditional definitions; includes misgendering, deadnaming, and the questioning or outright denial of one’s gender identity; and is particularly pervasive in masculinity contest cultures. These experiences are associated with both negative well-being of transgender employees and less effectiveness of the organizations that employ them, though more causal evidence is needed. We also highlight critical conceptual and methodological gaps to guide future research. Much of the existing research on LGBTQ+ employees in the workplace has focused primarily on sexual minorities, leaving the unique experiences of gender minorities invisible. Further, an intersectional lens is needed, as harassment experiences of trans women, trans men, and nonbinary people may differ in significant ways. Finally, we identify strategies to improve workplace climate including both top-down formal policy and bottom-up interpersonal behaviors. Full article

This paper examines migration from Africa as a response to shifting identities and the resurgence of nationalism, bringing biblical traditions into dialogue with contemporary realities. In many African contexts, contested identities, ethno-religious nationalism, and exclusionary state policies intensify conditions of displacement alongside poverty, conflict, and terrorism. As a result, migration becomes both a survival strategy and a negotiation of identity in an increasingly fragmented world. Biblical narratives of forced migration provide an interpretive framework for understanding these movements. The Hebrew Bible recounts exilic experiences, such as the Babylonian deportation, that reshaped Israel’s communal memory, identity, and theology. Similarly, the New Testament highlights dispersions caused by persecution, showing how migration functioned as a catalyst for the expansion of faith communities and the reconstruction of belonging. These texts illuminate how forced migration is not only a consequence of crisis but also a transformative process that redefines identity and community. By employing sociological and theological methods, this study demonstrates how African migration in the context of nationalism parallels biblical paradigms of exile and dispersion. It argues that African migrants’ narratives of identity, marked by struggle, hope, and resilience, echo biblical testimonies of displacement and offer theological resources for interpreting migration today. In doing so, this paper contributes to interdisciplinary debates on migration by showing how biblical exilic traditions can inform responses to Africa’s ongoing challenges of nationalism, identity, and forced movement.

The South African Government prioritises Small, Micro-, and Medium Enterprises (SMMEs) as catalysts for employment creation, in alignment with Sustainable Development Goal 8 (SDG 8), Decent Work and Economic Growth, which advocates for sustained, inclusive, and sustainable economic growth. However, the extent to which agro-processing SMMEs translate this policy ambition into measurable socio-economic gains remains contested due to persistent structural, financial, and operational constraints. This study develops a comprehensive, data-driven business support framework tailored to agro-processing SMMEs in the Free State province of South Africa. Employing a mixed-methods approach, survey data from 88 agro-processing SMMEs were analysed across 18 business performance dimensions. Average agreement scores and performance gaps were utilised to diagnose strengths and vulnerabilities within the sector. While overall performance was relatively strong (average agreement score: 86.7%), a critical weakness emerged in operational cost management (76.1%), revealing a 14.2% gap relative to the highest-performing dimension, equipment selection (90.3%). Based on these empirical insights, the study proposes a three-tiered business support architecture: (i) maintaining and leveraging high-performing dimensions (≥85% agreement), (ii) targeted enhancement for moderate-performing areas (80–84.9%), and (iii) crisis intervention for critical weaknesses (<80%). The framework integrates cross-cutting support services, including financing, regulatory guidance, and technology access, delivered through a phased implementation strategy comprising crisis intervention, system establishment, and optimisation and scaling. A multi-channel delivery mechanism, combining a hub-and-spoke model, mobile support units, and a digital platform, ensures provincial accessibility. By translating performance diagnostics into differentiated policy action, the framework promotes efficient resource allocation, supports both high-potential and vulnerable agro-processing SMMEs, and embeds a robust monitoring and evaluation system to track key performance indicators. The study contributes to the SMME development literature by demonstrating how structured, tiered, and context-specific support models can strengthen resilience, competitiveness, and sustainable agro-industrial growth in developing-country settings.

South African universities remain shaped by unresolved colonial inheritances and a deepening neoliberal turn that privileges measurable outputs, competition, and narrow definitions of merit. Within this landscape, Black academics and students often encounter institutional cultures that regulate belonging and constrain transformation. While accounts of the neoliberal university have been richly documented, less attention has been given to mentorship as an everyday institutional practice through which such regimes are reproduced and contested, particularly within professional training contexts. This paper offers a State of the Academy Address through the perspectives of two Black early-career clinical psychologists in academia. Drawing on collaborative autoethnography, a qualitative approach in which researchers use their own lived experiences as data to examine broader cultural patterns, and reflexive thematic analysis (a method of identifying and interpreting patterns of meaning across qualitative data) of structured reflective dialogues, we examine how emerging scholars attempt to re-make academic life through refusal and care. Two themes are presented: promoting mentorship while rejecting gatekeeping, and the tension between knowledge production and scholarly development under metric-driven performativity. The paper appreciates the notions of relationality and relational ethics, which are central to Ubuntu philosophy. Additionally, by centering a Freirean commitment to critical consciousness and empowerment, we argue that mentorship can function as an everyday agency that challenges exclusionary traditions, even as output pressures narrow scholarly formation and deepen the vulnerability of early-career academics. We conclude with implications for policy and practice across departmental, institutional, and sector levels, including the formal recognition of mentorship in workload models, protections for early-career academics against exploitative workload practices, and broader promotion and performance criteria that recognise relational labour, collaborative scholarship, and community-engaged knowledge production.

Cryptocurrencies are widely recognised for catalysing distributed ledger technologies and tokenisation, innovations that are transforming payment systems globally. However, their role as money is often contested and the subject of intense academic and policy debate. Nevertheless, new taxonomies of money allocate a unique place for cryptocurrencies. Described based upon a few high-level features, cryptocurrencies, except for stablecoins, are assumed to be a uniform group that can indeed be studied and categorised as such. Moreover, the logic of their creation is often looked at from a broad decentralisation and disintermediation perspective and remains ambiguous and questionable at best. This paper reports the findings of a clinical investigation into the top 30 cryptocurrencies representing 95.5% of the total crypto market capitalisation. This study is primarily concerned with their logic of creation, and how they compare with that of fiat money and central bank digital currencies. The findings reveal that, unlike fiat money, and CBDCs, crypto mechanics depict a diverse assortment of logics. The evidence suggests that despite widespread technical innovations, the crypto ambition to provide an alternative to centrally controlled debt-based fiat money has managed to add a combination of transaction validation, mathematical guesswork, pseudo-randomness, and size dependent probability as alternative logics of creation and allocation. While centrally managed bank-controlled debt-based fiat money leaves a lot to be desired, protocol-managed, code-controlled, size-dependent probabilistic money does not seem like much of an upgrade. This paper addresses the limits of tokenisation as a transformational tool and argues that cryptocurrencies may have helped trigger improvements in the technology of money, but not in its logic of creation. Indeed, to compete in the emerging monetary landscape it has helped create, i.e., the ubiquitous tokenisation of debt and debt-based fiat money, the crypto revolution will have to extend its value proposition beyond technology and pseudo-randomness.

Spacecraft pursuit–evasion in contested environments is complicated by strategic incompleteness: the evader can switch maneuvering modes and deploy multi-domain countermeasures that degrade the pursuer’s perception, leading to non-stationary information and distributionally ambiguous interference statistics. A dynamic time-window Nash equilibrium framework is developed for linearized Local Vertical Local Horizontal (LVLH) relative motion under interference-induced uncertainty. Perceptual degradation is modeled via an evidence–theoretic belief representation, and the Jensen–Shannon (JS) divergence is introduced to quantify discrepancies between nominal and interference-corrupted beliefs. The divergence metric drives an adaptive time-window partitioning policy and an uncertainty-aware running cost that balances nominal performance objectives with robustness regularization during high-degradation intervals. In each time window, sufficient conditions are provided for the existence of a local Nash equilibrium, and equilibrium strategies are characterized by the Hamilton–Jacobi–Bellman–Isaacs (HJBI) equation. A global consistency result is established: assuming state continuity, additive cost decomposition, and dynamic-programming compatibility at window boundaries, concatenating the window-wise equilibria yields a Nash equilibrium over the entire horizon. Unlike conventional receding-horizon differential games with a fixed replanning grid, the proposed policy partitions the horizon online in response to perceptual-degradation events and stitches adjacent windows through a continuation value. This boundary stitching enables the global consistency guarantee under additive costs and state continuity. To hedge against ambiguity in interference intensity, a variational distributionally robust optimization (DRO) problem with moment-constrained ambiguity sets is formulated, and the dual worst-case distribution is derived. The resulting Karush–Kuhn–Tucker (KKT) system is reformulated as a finite-dimensional variational inequality, for which an accelerated Alternating Direction Method of Multipliers (ADMM) operator-splitting solver is proposed for efficient real-time computation. Numerical simulations validate the framework and demonstrate improved robustness and computational scalability under time-varying interference compared with fixed-window baselines. Full article

Generally portrayed as a neutral framework, the Common European Framework of Reference for Languages (CEFR) is implemented in various contexts through unequal policy transfers that favour Global North perspectives. The CEFR has become a key policy tool for curriculum internationalisation worldwide, particularly in higher education institutions in the Global South that seek international recognition. This qualitative study uses a critical policy transfer and policy enactment approach to examine how lecturer agency influences CEFR-based curriculum internationalisation in Indonesian postgraduate English programs, especially those aiming for the C1/C2 level. Informed by Priestley, Biesta, and Robinson’s ecological model of agency, the analysis reveals that lecturers employ interpretive, adaptive, and transformative agency to counter deficit narratives, integrate global standards with local pedagogical principles, and redefine CEFR C1/C2 as a construct of contextual significance. Rather than implementing the CEFR as a fixed benchmark, lecturers act as epistemic and cultural brokers who reclaim curriculum internationalisation as a locally grounded pedagogical project. The study advances debates on the CEFR, policy transfer, and Global South internationalisation by foregrounding lecturer agency as a critical site where global language policies are negotiated, contested, and reworked.

This study employs cooperative, behavioural, and experimental game theory to examine how forest rights are negotiated among tribal communities, government agencies, and civil society organisations in the western Himalayas. It explores how claims over access, governance, and benefit-sharing regarding forest resources are asserted, contested, and mediated in a complex socio-political environment. This research adopts a mixed-methods approach. Qualitative data from in-depth interviews and focus group discussions. Quantitative data from structured surveys and field-based experiments. The findings underscore the importance of integrating traditional knowledge systems with modern development policies. This study emphasises the need for sustainable and inclusive strategies that protect both the environment and local livelihoods. Full article

The endogenous security paradigm has emerged to address the limitations of traditional cybersecurity, which relies on reactive “patching” and struggles against unknown threats, APTs, and supply chain attacks. Centered on the principle that “structure determines security”, it diverges from detection-based approaches by employing systems theory and cybernetics to architect closed-loop systems with “heterogeneous execution, multimodal adjudication, and dynamic scheduling”. This is realized through intrinsic architectural constructs such as dynamism, heterogeneity, and redundancy. Theoretically, it transforms deterministic component-level attacks into probabilistic system-level events, thereby shifting the security foundation from a “cognitive contest” to an “entropy-driven confrontation”. This paper provides a comprehensive review of this paradigm. We begin by elucidating its philosophical foundations and core axioms, focusing on the Dynamic Heterogeneous Redundancy (DHR) model, which converts attacks on specific vulnerabilities into probabilistic events under the core assumption of independent heterogeneous execution entities. Next, we trace the architectural evolution from early mimic defense prototypes to a universal framework, analyzing key developments including expanded heterogeneity dimensions, intelligence-driven dynamic policies, and enhanced adjudication mechanisms. We then explore essential enabling technologies and their integration with cutting-edge trends such as artificial intelligence, 6G, and cloud-native computing. Through case studies of the 5G core network and intelligent connected vehicles, the engineering feasibility of the endogenous security paradigm has been validated, with quantifiable security gains demonstrated. In a live-network pilot of the endogenous security micro-segmentation system for the 5G core, resource consumption (CPU/memory usage) of network function virtual machines remained below 3% under steady-state service loads. The system concurrently maintained microsecond-level forwarding performance and achieved carrier-grade core service availability of 99.999%. These results demonstrate that the endogenous security mechanism delivers high-level structural security with an acceptable performance cost. The paper also critically summarizes current theoretical, engineering, and ecosystem challenges, while outlining future research directions such as “Endogenous Security as a Service” and convergence with quantum-safe technologies.

This article examines how everyday architecture can advance spatial justice in post-active conflict cities through ethnographic and participatory design. Drawing on a decade of work by the StreetSpace studio in Belfast (2015–2025), the paper explores how architecture students and community participants co-design spatial strategies that enhance mixed-use mid-density living, inclusive mobility, and street-level accessibility. In a context where car dominance, segregation, and privatisation of public space continue to fragment urban life, the everyday street becomes a testbed for envisioning an equitable and community-centred city. The studio’s methodology is grounded in ethnographic engagement, informed by an embedded anthropologist, and includes stakeholder mapping, walking workshops, and collaborative drawing. These practices reveal lived experiences and shape community-driven briefs for housing, schools, public spaces, and multifunctional infrastructure. Anchored in spatial justice discourse and feminist theory (Jane Jacobs, David Harvey, Roberto Rocco, Phil Hubbard, Leslie Kern, and Caroline Criado Perez), the work positions the everyday as a site of architectural agency and proposes a contemporary vernacular that is socially embedded and climate-resilient. This work unfolds through complex and often contested processes that require sustained, iterative engagement with people and places. Meaningful collaboration is neither linear nor inherently caring; it frequently involves conflict, disagreement, and competing priorities that must be navigated over time. Through long-term relationships with government departments, local authorities, and NGOs, StreetSpace demonstrates how architectural pedagogy can nonetheless contribute to policy formation and more inclusive urban redevelopment by engaging in compromise, critical negotiation, and moments of care alongside friction and resistance. Through a series of collaborations and public events the project has contributed to the transformation of Botanic Avenue, informed studies of the East Belfast Greenways through contributions to Groundswell and participated in embedded public processes in collaboration with PPR, culminating in an exhibition at the MAC in Belfast in 2025.

This study examines the social, economic and cultural impacts that Latin American women face due to climate-induced displacement, considering these impacts as arenas of conflict and negotiation. Using an intersectional framework, the study analyses how climate disasters exacerbate structural inequalities rooted in patriarchal systems, thereby constraining women’s adaptive capacity while simultaneously catalysing resistance strategies. Through a comparative analysis of Bangladesh and the Dry Corridor in Central America using a Gender Vulnerability Index (GVI), the study reveals that displaced women navigate contested spaces, disputing access to resources, legal recognition and territorial belonging, while constructing transnational solidarity networks and cooperative economies. The emergence of women climate refugees challenges international legal frameworks, exposing critical gaps in protection regimes. The findings emphasise the need for gender-responsive policies that recognise women as transformative agents who negotiate power asymmetries in contexts of environmental crisis, not merely as vulnerable populations. This research contributes to our understanding of the nexus between climate change, gender and migration by foregrounding the dialectic of domination and agency in Latin American displacement processes.

Organic pig farming in Europe is endorsed as a promising route to more sustainable livestock production, but its ultimate contribution to the United Nations (UN) Sustainable Development Goals (SDGs) is a contested matter. This study takes a critical perspective on the potential of organic pig farming to contribute to SDGs that may include SDG 2 (Zero Hunger), SDG 3 (Good Health and Well-being), SDG 8 (Decent Work and Economic Growth), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), and SDG 15 (Life on Land). Organic farming systems delivered better animal welfare outcomes and positive benefits for biodiversity, soil health, and rural employment. Continued improvements in sourcing feed, greenhouse gas emissions per unit of product, animal health, and market could improve their contributions to agricultural sustainability. This study concludes that organic pig farming does not represent a guarantee of sustainable livestock production, but it could represent credible sources of sustainable livestock innovation if sufficient policy, practice, cost accounting, and sustainable metrics are organized together to support organic systems. Organic pig farming focused on innovation and policy support can make it a role model for the transition of European livestock sector towards the 2030 Agenda. Full article

Digitalization is widely heralded as a catalyst for growth, yet its role in achieving the United Nations’ Sustainable Development Goal 10 (Reduced Inequalities) remains deeply contested. Moving beyond linear assumptions of “digital dividends,” this study adopts a complex socio-technical systems perspective to unravel the configurational pathways linking digitalization to national income inequality. We analyze a high-quality balanced panel of 56 major economies from 2012 to 2022. Employing Panel Fuzzy-Set Qualitative Comparative Analysis (Panel fsQCA) and Necessary Condition Analysis (NCA), this study proposes an evidence-based typology of digitalization-inequality pathways. We reveal that the impact of digital transformation is asymmetric and contingent on geo-economic contexts. NCA identifies Digital Infrastructure, Innovation, and Governance as necessary “bottlenecks” for social equity. Sufficiency analysis uncovers three distinct sustainable development modes: an “Open Innovation Mode” in affluent small economies, driven by global integration and technological frontiers; a “Governance-Regulated Industry Mode” in major economies, where strong state capacity regulates digital industrial scale; and an “Open Niche Mode” for transition economies, leveraging openness to bypass domestic structural deficits. Conversely, we identify a critical “Hollow Governance Trap” in the Global South, where digital governance efforts fail to reduce inequality in the absence of real industrial and infrastructural foundations. These findings challenge one-size-fits-all policies, suggesting that bridging the global digital divide requires context-specific strategies—ranging from synergistic integration to asymmetric breakthroughs—that align digital investments with institutional capacity.

Insufficient investment in wildlife that lacks strong aesthetic or emotional appeal to humans poses a significant obstacle to achieving broader conservation goals. Species that are not considered charismatic are nonetheless vital to ecosystems and deserve attention from conservationists, researchers, and the public. However, effective strategies for bridging the gap between these species and traditionally charismatic ones remain underexplored. Our exploratory study introduced the concept of charisma orientations to examine their influence on pro-bird behaviors, such as following guidelines, reporting disturbances, and participating in community advocacy. We identified six relational and socially negotiated orientations—ecological importance, intrinsic right to exist, protection support, affective meaning, and perceived decline—that together represent key perspectives through which waterbirds are understood. A survey of 615 Texas coastal recreationists revealed that relying solely on positive charisma diminishes the appeal of waterbirds for participants. The species likeability frame was relevant only in the context of reporting disturbances, while a moral policy stance (the belief that waterbirds need protection) was significant in predicting advocacy. Younger males and individuals who felt current regulations were adequate were less likely to engage in waterbird conservation behaviors. Our findings suggest that examining the intersection of contested charismatic species and various charisma orientations can uncover subtle nuances often overlooked due to an overemphasis on positive charisma and emotional resonance, which may only partially apply or not apply at all.
