The rise in social media has blurred work–life boundaries, and concerns have been raised about its impact on employee well-being. This study examines how excessive social media use at work (ESMU) and social media use for work during non-work hours (SMUNW) affect turnover intention. Social media exhaustion is tested as a mediator, and resilience is tested as a moderator. Survey data were collected from 453 civil servants in Shandong Province, China. Hierarchical regression and the PROCESS MARCO were used for analysis. The results indicate that ESMU (β = 0.42, p < 0.001) and SMUNW (β = 0.14, p < 0.01) both significantly increase turnover intention. Social media exhaustion mediates these relationships, while resilience reduces their negative impact. Our findings contribute to technostress research by clarifying how digital demands influence public employees. For managers and organizations, the results highlight the need to set boundaries for work-related social media use; monitor employees’ digital exhaustion; and foster resilience through recruitment, training, and organizational support.

Voids have a crucial effect on the fatigue performance of materials. The general viewpoint is that voids, as possible sources of cracks, are harmful to the fatigue performance of materials. However, this study finds that microvoids enhance the low-cycle fatigue resistance of TiAl alloys, both in single crystal and polycrystal, using molecular dynamics simulations. Due to the difference between the simulation and test, the selected strain value is larger. It is found that during cyclic loading, Shockley partial dislocations preferentially nucleate around the microvoid in the single crystal, with stacking fault tetrahedra forming progressively to obstruct dislocation motion. The polycrystal model exhibits the synergistic effect of the microvoid–grain boundary, and the fatigue resistance is substantially enhanced through the combined mechanisms of Lomer–Cottrell lock formation, twin boundary migration, and phase transformation. In addition, simulation models with microvoids exhibit lower plastic strain energy density and enhance fatigue life compared to microvoid-free counterparts. The present study provides significant insights into designing γ-TiAl alloys through controlled microvoids to optimize fatigue resistance. Future work should include experimental validation to substantiate these computational findings. Full article

Advances in AI and Brain–Computer Interfaces (BCIs) like Neuralink’s invite constructive Christian ethical responses that capitalize on these increasingly powerful technologies. This paper offers such a response. Its thought experiment partly draws on Immanuel Kant’s work Religion Within the Boundaries of Mere Reason in which he argues that the Son of God is the prototype of the perfectly good person and, as such, serves as the ideal model for anyone seeking to lead a moral life. Working within this Kantian framework, the anticipated capabilities of BCIs and AI could assist humans make moral progress and support their efforts to imitate the Son of God. These two technologies, coupled with a computer science approach to AI ethics known as Conditional Preference Networks, or CP-nets, offer a path forward. A case study in which a medical doctor with access to only one donor kidney must choose between two patients illustrates how BCIs and AI can help. Full article

This study attends to employees’ boundary-setting enactments during workplace resocialization following parental leave in the United States. We qualitatively analyzed the work/life boundary-setting enactments of 16 employees who returned to the workplace following parental leave using the dialectical lens of control (organizational assimilation) and resistance (individualization). Findings illustrate how employees managed tensions that generated an overarching work/life paradox during organizational resocialization across identity, time, and topic boundary-setting stressors. Employees’ tensioned enactments illustrated a control/resistance dialectic whereby paradoxical responses (vacillating, integrating, and/or balancing) were used to align with professional norms or privilege a working parent identity. This study contributes to paradox research and the model of organizational socialization to deepen our theoretical understanding of how resocialization is a communication process where managing work/life paradoxical responses to identity, time, and topic stressors can attenuate dialectical organizational tensions. Furthermore, we offer practical recommendations for organizations, supervisors, and individuals to productively understand and approach tensions. Full article

To address the high fossil energy dependency and the low-value utilization of stillage (WDGS) in conventional cassava-based ethanol production—factors that increase greenhouse gas emissions and limit overall sustainability—this study develops an integrated ethanol–biogas–CHP system that valorizes stillage and enhances energy recovery. Three process scenarios were designed and evaluated through life cycle assessment (LCA) and techno-economic analysis: Case-I (WDGS dried and sold as animal feed), Case-II (stillage anaerobically digested for biogas used for heat), and Case-III (biogas further utilized in a combined heat and power system). Process simulation was conducted in Aspen Plus V11, while environmental impacts were quantified with the CML 2001 methodology under a cradle-to-gate boundary across six categories, including global warming potential (GWP) and abiotic depletion potential (ADP). Results show that Case-III achieves the highest environmental and economic performance, with a net GWP of −1515.05 kg CO₂-eq/ton ethanol and the greatest profit of 396.80 USD/ton of ethanol, attributed to internal energy self-sufficiency and surplus electricity generation. Sensitivity analysis further confirms Case-III’s robustness under variations in transportation distance and electricity demand. Overall, valorizing cassava stillage through biogas–CHP integration significantly improves the sustainability of ethanol production, offering a practical pathway toward low-carbon bioenergy with potential for negative emissions. This study fills a gap in previous life cycle research by jointly assessing WDGS utilization pathways with techno-economic evaluation, providing actionable insights for carbon-neutral bioenergy policies in cassava-producing regions. Certain limitations, such as software version and data accessibility, remain to be addressed in future work. Full article

Background: In low-resource health systems, official mHealth platforms often face usability and infrastructure barriers. In India, Community Health Workers (CHWs) and their supervisors have pragmatically turned to WhatsApp as an informal digital infrastructure. While widely adopted, its dual role as both a support system and a source of burden remains underexplored. Aim: To examine the patterns and purposes of WhatsApp use among CHWs and block-level supervisors; to identify perceived benefits, barriers, and risks; and to assess its influence on workflow, power relations, digital equity, and program outcomes in an Indian Aspirational District. Methods: We conducted a qualitative study between June and December 2023 in Muzaffarpur, Bihar, India. Data comprised 32 in-depth interviews and six focus group discussions with CHWs (Anganwadi Workers, ASHAs, ANMs) and block-level public health officers (total participants n = 81). We used reflexive thematic analysis following Braun and Clarke’s approach; reporting adhered to the COREQ guideline. Results: WhatsApp emerged as a de facto digital backbone for real-time communication, peer support, and program supervision, often perceived as more usable than official applications. Its informal adoption also created a triple burden: digital fatigue from information overload and blurred work–life boundaries; duplication of reporting across WhatsApp and official portals; and systemic inequities that disadvantaged older or less digitally literate CHWs, with risks of surveillance creep and data privacy breaches. Conclusion: WhatsApp simultaneously enables coordination and imposes workload and equity costs on India’s frontline workforce. Without formal policy and governance, this user-driven adaptation risks widening digital divides and accelerating burnout. We recommend clear protocols on purpose-limited use, investments in equitable digital capability and devices, and safeguards that protect worker well-being and data privacy. Full article

This study presents a novel and interpretable, deployment-ready framework for predicting cybersecurity incidents through item-level behavioral, cognitive, and dispositional indicators. Based on survey data from 453 professionals across countries and sectors, we developed 72 logistic regression models across twelve self-reported incident outcomes—from account lockouts to full device compromise—within six analytically stratified layers (Education, IT, Hungary, UK, USA, and full sample). Drawing on five theoretically grounded domains—cybersecurity behavior, digital literacy, personality traits, risk rationalization, and work–life boundary blurring—our models preserve the full granularity of individual responses rather than relying on aggregated scores, offering rare transparency and interpretability for real-world applications. This approach reveals how stratified models, despite smaller sample sizes, often outperform general ones by capturing behavioral and contextual specificity. Moderately prevalent outcomes (e.g., suspicious logins, multiple mild incidents) yielded the most robust predictions, while rare-event models, though occasionally high in “Area Under the Receiver Operating Characteristic Curve” (AUC), suffered from overfitting under cross-validation. Beyond model construction, we introduce threshold calibration and fairness-aware integration of demographic variables, enabling ethically grounded deployment in diverse organizational contexts. By unifying theoretical depth, item-level precision, multilayer stratification, and operational guidance, this study establishes a scalable blueprint for human-centric cybersecurity. It bridges the gap between behavioral science and risk analytics, offering the tools and insights needed to detect, predict, and mitigate user-level threats in increasingly blurred digital environments.

At present, the decarbonization of the public transport sector plays a key role in international and regional policies. Among the various energy vectors being considered for future clean bus fleets, green hydrogen and electricity are gaining significant attention thanks to their minimal carbon footprint. However, a comprehensive Life Cycle Assessment (LCA) is essential to compare the most viable solutions for public mobility, accounting for variations in weather conditions, geographic locations, and time horizons. Therefore, the present work compares the life cycle environmental impact of different powertrain configurations for urban buses. In particular, a series hybrid architecture featuring two possible hydrogen-fueled Auxiliary Power Units (APUs) is considered: an H2-Internal Combustion Engine (ICE) and a Fuel Cell (FC). Furthermore, a Battery Electric Vehicle (BEV) is considered for the same application. The global warming potential of these powertrains is assessed in comparison to both conventional and hybrid diesel over a typical urban mission profile and in a wide range of external ambient conditions. Given that cabin and battery conditioning significantly influence energy consumption, their impact varies considerably between powertrain options. A sensitivity analysis of the BEV battery size is conducted, considering the effect of battery preconditioning strategies as well. Furthermore, to evaluate the potential of hydrogen and electricity in achieving cleaner public mobility throughout Europe, this study examines the effect of different grid carbon intensities on overall emissions, based also on a seasonal variability and future projections. Finally, the present study demonstrates the strong dependence of the carbon footprint of various technologies on both current and future scenarios, identifying a range of boundary conditions suitable for each analysed powertrain option.

Life cycle assessment (LCA) is a standardized tool (ISO 14040) used to evaluate the environmental impacts of products and processes across their entire life cycle, from raw material extraction to end-of-life disposal or recycling. It has become particularly important in the context of engineering materials, where sustainability considerations are critical. Despite challenges such as data quality limitations, variations in system boundary definitions, and methodological inconsistencies, LCA remains an essential tool for assessing and improving product sustainability. This work presents a foundational overview of LCA principles and describes a systematic, step-by-step procedure for its effective application. Additionally, this article revisits the fundamental concepts of carbon footprint (CF) analysis as a complementary tool for quantifying greenhouse gas emissions associated with products and activities. CF analysis underscores the necessity of adopting low-carbon materials and manufacturing processes to minimize embodied energy and reduce environmental emissions. Low-carbon materials are characterized by attributes such as being lightweight, recyclable, renewable, bio-based, locally sourced, and safe for public health. Their development balances the reduction of raw material and resource consumption during production, with increasing product performance, recyclability, and service life, reflecting a cradle-to-cradle, circular economy approach. The integration of LCA and CF methodologies provides an integral framework for assessing environmental performance and supports decision-making processes aligned with global sustainability targets.

The rapid advancement in information and communication technologies (ICT) has improved workplace productivity but also introduced new psychosocial stressors. Workplace telepressure, the urge to respond quickly to work-related messages sent via digital communication tools, often erodes employees’ psychological well-being and blurs work–life boundaries. This study, grounded in the Job Demands–Resources (JD-R) model, investigates the influence mechanism between workplace telepressure and job burnout. Using data collected from 323 middle school teachers in China, results revealed that workplace telepressure significantly predicted job burnout. In addition, work-related rumination partially mediated this relationship, indicating a cognitive mechanism linking telepressure and burnout. Furthermore, perceived organizational support moderated the relationship between work-related rumination and job burnout. Specifically, when perceived support was high, the impact of rumination on burnout was weakened. These findings provide theoretical insights and practical implications for fostering healthy work environments and promoting psychological well-being in the digital era. Full article

Work–life balance (WLB) is central to sustainable social and economic development, as reflected in the UN Sustainable Development Goals 3, 5, and 8. The purpose of this article is to identify and examine the key organisational and personal factors influencing the perceived work–life balance of employees in rural areas. The theoretical framework is grounded in three complementary approaches: the job demands–resources (JD-R) model, spillover theory, and boundary theory. Together, they offer a comprehensive perspective on role dynamics in the context of limited resources, technostress, and family-related tensions. The study was conducted on a sample of 700 rural employees in Poland, predominantly women (60.6%), with the majority aged 35–55 years (53.0%). Data were collected via a structured questionnaire and analysed using an exploratory approach based on regression trees (CART), which are effective in identifying latent and multidimensional relationships. The findings highlight the mechanisms underlying WLB disruptions in rural contexts and pinpoint areas for intervention through public and organisational policies aimed at supporting employee well-being. The most influential factors were workplace comfort, work flexibility, time autonomy, and employee age. Notably, younger employees require better working conditions than older ones to achieve similar WLB levels. The CART analysis also indicates that some disadvantages, such as low workplace comfort, can be mitigated by more flexible work schedules. Employers should therefore provide multidimensional support through complementary measures, monitor job demands, and educate employees on the effective use of available resources. Full article

Work–life balance (WLB) in academia remains a challenge as a result of increasing workloads, precarious employment, and expectations of constant availability. The COVID-19 pandemic exposed these structural barriers to work–life balance in academia and also clearly showed the inequities related to hybrid and remote work for women, caregivers, and underrepresented minorities. This paper highlights the key factors that pose challenges to WLB in academia, how these challenges have been worsened by COVID-19, and what we can learn from pandemic times solutions to devise inclusive practices for long-term structural change. The methodology used in this paper is a critical review of 298 published articles. This review is structured as follows: The structural barriers, inequities, and workplace policies that impact academic WLB are first inventoried. Then, the lessons learned from the pandemic are studied by dividing the short-term disruptions from the permanent shifts. Finally, inclusive solutions, focusing on institutional boundary-setting, workload redistribution, hybrid work policies, and mental health support are presented. This paper makes three key contributions: (1) it provides an intersectional understanding of WLB, accounting for gender, caregiving, ethnicity, migration, and social class; (2) it frames COVID-19 as a driver for structural reform, rather than an anomaly; (3) it bridges WLB research and policy design, proposing actionable strategies for universities and policymakers. By placing equity and inclusion at the core of the analysis, this work advocates for systemic solutions that promote a sustainable academic environment aligned with principles of social justice.

The Apple TV+ series Severance (2022–present) offers a dystopian portrayal of workplace life that intensifies real-world dynamics of control, boundary management, and identity regulation. This paper analyzes Severance as a speculative case study in organizational theory, treating the show’s fictional world as a site for conceptual reflection. Drawing on critical management studies and labor process theory, we examine how mechanisms of control, the regulation of work–life boundaries, and the fragmentation of autonomy and subjectivity are depicted in extreme form. We argue that fiction—particularly speculative satire—can serve as a tool of theoretical production, not merely illustration. Rather than restating familiar critiques, Severance allows us to see workplace norms with renewed clarity, surfacing the moral and psychological consequences of surveillance, coercion, and instrumentalized consent. A methodological note outlines our interpretive approach to narrative fiction, and a discussion of implications situates the analysis within broader debates about organizational ethics, resilience, and critique.

This article examines the concept of ming 命 (mandate/command or fate/destiny) in the Analects, Mencius, and Zhuangzi, exploring its relationship to tian 天 (Heaven). Across these works, ming retains an intrinsic connection to tian—an inviolable cosmic force beyond human control. All three texts exhibit profound reverence and submission to tian, acknowledging the boundary between human control and cosmic inevitability, yet, at the same time, advocating active alignment with tian’s ordained patterns. In the Analects, a central tension emerges between tian’s teleological purpose—centered on preserving human culture and ethical cultivation—and the seemingly arbitrary fluctuations of individual fate, particularly regarding lifespan and personal fulfillment. This tension persists in the Mencius, articulated as a conflict between the political disorder of Mencius’ contemporary era and tian’s normative moral order. The Zhuangzi, by contrast, resolves this tension through advocating for withdrawal from the political life, as well as a radical reinterpretation of tian. Stripping tian off the Confucian moral–cultural imperatives, the text deconstructs dichotomies like life and death, championing inner equanimity via flowing with the cosmic transformation.

The COVID-19 pandemic has exposed and intensified structural tensions surrounding work−life balance, precarity, and gender inequalities in academia. This paper examines the spatial, temporal, and emotional disruptions experienced by early-career and precarious researchers in Italy during the first national lockdown (March–April 2020) and their engagement in remote academic work. Adopting an exploratory and qualitative approach, the study draws on ten narrative video interviews and thirty participant-generated images to investigate how structural dimensions—such as gender, class, caregiving responsibilities, and the organizational culture of the neoliberal university—shaped these lived experiences. The findings highlight the implosion of boundaries between paid work, care, family life, and personal space and how this disarticulation exacerbated existing inequalities, particularly for women and caregivers. By interpreting both visual and narrative data through a sociological lens on gender, work, and organizations, the paper contributes to current debates on the transformation of academic labor and the reshaping of temporal work regimes through the everyday use of digital technologies in contemporary neoliberal capitalism. It challenges the individualization of discourses on productivity and flexibility and calls for gender-sensitive, structurally informed policies that support equitable and sustainable transitions in work and family life, in line with European policy frameworks.
