Technostress's impact on well-being and turnover intent: comparing mediation and network analysis
Publication . Pinheirinho Coelho, Pedro; Antunes, João Paulo; Neves de Jesus, Saúl
Purpose – As information technology becomes more ubiquitous in the workplace, it becomes increasingly important to understand how employees’ experiences with these technologies impact their well-being and turnover intention. Technostress, the inability to relate to new technologiesin a positive way, has been studied as a cause of turnover, but these studies tend to ignore the possibility of turnover intention also leading to heightened feelings of technostress. Design/methodology/approach – The present study aimed to assess the relationship between technostress, well-being and turnover intent (TI) among a sample of 428 workers, through both a top-down (mediation) and a bottom-up (network analysis) methodology. Findings –Results coincided with previous models ofturnover, indicating that turnoverintention usually results from reduced workplace well-being, originating from technostress. Yet, network analysis showed that TI had a significant relationship with both technostress and well-being, indicating that a positive feedback loop might be present in this process. The results highlight the importance of constant training in information technology to maintain worker well-being and reduce turnover. Originality/value – This is the first paper to compare mediation with network analysis within TI. Beyond identifying cyclical effects, the paper identifies how different elements of technostress affect TI and the pathways through which this association is established.
Palaeoenvironments, stratigraphy and taphonomy of an Upper Triassic vertebrate-bearing unit, Silves Group, central Algarve, southern Portugal

Triassic to Lower Jurassic deposits known as the Silves Group in the Algarve, southernPortugal, have been studied for over 150 years. However, many of this unit’s sedimento-logical, stratigraphical, and palaeontological aspects remain poorly documented. Here, we present novel observations on sedimentology, stratigraphy, taphonomy, and fauna atthe Rocha da Pena site, located in the central part of the Algarve Basin. The investigatedsequence is established to correspond to the upper part of the Silves Group. The mud-stone, calcrete, and palustrine carbonate facies comprise most of the sequence thicknessand are interpreted as having been deposited within coastal alluvial mudflats to palus-trine settings under semi-arid and seasonal climates. The overlying siltstone and sand-stone facies indicate an environmental shift towards tidally influenced environments,subsequently covered by the latest Triassic to earliest Jurassic volcaniclastics and basalticlava flows. Furthermore, novel faunal elements, including actinopterygian and union-oid bivalves, are described from mudstone layers. New fossiliferous beds are identifiedwithin palustrine facies that yield numerous but poorly preserved materials assigned tocyamodontoid placodonts, hybodont sharks, and actinopterygians. The poor preserva-tion of the remains is attributed to the pedogenetic processes prevalent in the palustrinedepositional setting. A distinct faunal composition between the mudstone and palustrinefacies is observed. It is preliminarily hypothesized to be likely linked with salinity fluctu-ations, but sampling bias cannot currently be excluded. The recovered vertebrate faunaaligns most closely with the Carnian and, to a lesser extent, the Norian fossil record.Nonetheless, the precise age of the fossil-bearing levels remains uncertain and can cur-rently be reliably constrained to the upper Carnian–Rhaetian interval. Consequently,this work provides new insights into the palaeoenvironmental evolution of the westernTethys margin during the Late Triassic and highlights the relevance of the Silves Groupin reconstructing coastal-continental ecosystem dynamics in southwestern Iberia.
Homological lemmas for (Non-abelian) group-like structures by diagram chasing in a self-dual context
Publication . Dayaram, Kishan Kumar; Goswami, Amartya; Janelidze, Zurab; Rodelo, Diana; Linden, Tim Van der
Through abelian categories, homological lemmas for modules admit a self-dual treatment, where half of the proof of a lemma is sufficient to prove the full lemma. In this paper we show how the context of a ‘noetherian form’, recently introduced by the second and third authors, allows a self-dual treatment of these lemmas even in the case of non-abelian categories of group-like structures. This context covers a wide range of examples: module categories, the category of groups, of graded abelian groups, the categories of Lie algebras, of cocommutative Hopf algebras, the category of Heyting semilattices, of loops, the dual of the category of pointed sets, the category of modular/distributive lattices and modular connections, the category of sets and partial bijections, and many others. More generally, it includes all semi-abelian and Grandis exact categories.
Integrating traditional knowledge into tourism climate policy: exploring feasibility and benefits in Iran’s world heritage sites
Publication . Esfehani, Minoo; Ghaderi, Zahed; Bagheri, Fatemeh; Hatamifar, Pezhman
Traditional knowledge, despite its recognized socio-ecological value, is often underestimated or excluded from climate policies, particularly within tourism contexts. Using qualitative research, this study employed purposive sampling to interview 16 participants to explore (a) the feasibility of integrating traditional knowledge into tourism climate policy in World Heritage Sites and (b) the potential benefits of such integration. Findings show that traditional knowledge can strengthen site resilience, support participatory management, and enhance climate capacity in both theory and practice, though several challenges remain. Theoretically, and grounded in environmental sociology, the study advances the current understanding of the sociocultural dimensions of tourism climate governance and advocates for epistemological pluralism and more inclusive policies that incorporate diverse knowledge systems. Practically, the evidence-based findings suggest that tourism policy should prioritize the application of community-rooted knowledge and practices, develop context-sensitive guidelines to integrate multiple knowledge systems into tourism climate actions, and disseminate effective methodologies and practices.
Transforming aquatic food systems through digital traceability: a review of global challenges and opportunities
Publication . Costa, Gisela; Pita, Cristina; Ferreira Alexandre, Teresa Sofia; Roumbedakis, Katina; Pontes, João; Hübel, Michelle; Rangel, Mafalda
Aquatic foods are among the most extensively traded food commodities globally, with increasingly complex supply chains and rising consumer demand for sustainable, ethically sourced, and legally compliant products. In this context traceability systems have emerged as vital tools for enhancing transparency, accountability, and resilience within these supply chains. This study presents a systematic review of the literature to identify key challenges and opportunities associated with the implementation of digital traceability systems in aquatic food supply chains. The review synthesizes evidence on diverse technologies, governance frameworks, and supply chain dynamics. The findings reveal that while technological innovation, such as blockchain and digital traceability platforms, show promising solutions for improving data management and efficiency, and enhance consumer trust, several barriers persist. These include high implementation and maintenance costs, technological barriers (e.g., complexity of data management and usability), stakeholder disinterest, unequal access to digital infrastructure, gaps in international cooperation and regulatory frameworks, and issues of system interoperability. Conversely, traceability presents multiple benefits, including enhanced supply chain efficiency, market access, stronger stakeholder collaboration, and alignment with consumer preferences for sustainable products. It also contributes to combating Illegal, Unreported, and Unregulated (IUU) fishing, enhancing fair labour practices, and promoting compliance with international standards. We conclude that inclusive, context-specific approaches (tailored to the diverse characteristics of fisheries, aquaculture, and small-scale operations) and crosssector collaboration are essential to address the challenges inherent in globalized supply chains and realize the full potential of traceability systems in advancing more sustainable, transparent, and resilient aquatic food systems.
