The decision between voice or exit in service cooperatives.
No full textThis study examines how job satisfaction influences constructive voice, destructive voice, and exit intentions within service cooperatives, drawing on Hirschman’s Exit-Voice-Loyalty (EVL) framework. Using survey data from 222 employees, a path model was employed to test both direct and moderated relationships. Results show that job satisfaction positively predicts constructive voice and negatively predicts destructive voice and exit intentions. Loyalty emerges as a key moderator, strengthening the positive link between satisfaction and constructive voice, while weakening the negative associations with destructive behaviours and exit. These findings underscore the importance of loyalty as a stabilising force that channels dissatisfaction into productive employee behaviours. By addressing both constructive and destructive voices alongside exit, the study provide an application of the EVL theory and enriches understanding of employee responses in cooperative contexts. Practical implications underscore the importance of nurturing loyalty to foster engagement, reduce turnover, and promote the cooperative spirit
Beyond Deterministic Scheduling: Revealing Hidden Critical Paths under Stochastic Time Variability through Monte Carlo Simulation and Hierarchical Clustering
No full textIn many Engineer-to-Order (ETO) companies, each one-of-a-kind product is effectively treated as a separate project, making the critical path a central tool for scheduling tasks and allocating resources. However, relying solely on deterministic durations may fail to capture the variability typical of real-world operations, leading to potentially inaccurate project timelines. Despite this challenge, the literature rarely explores how variable activity durations can lead to different critical paths, with significant implications for both project duration and resource allocation. This study tackles this gap by integrating optimistic and pessimistic duration estimates within a Monte Carlo Simulation (MCS), systematically recording and analyzing all the critical paths actually observed. By quantifying how frequently each activity appears among these paths, a hierarchical clustering method is employed to detect recurring patterns and correlations. From the results, it emerges that the deterministic critical path can diverge from the one that arises under variable conditions, highlighting which tasks require greater attention to prevent delays. Consequently, the proposed framework offers a comprehensive basis for resource allocation in ETO environments, illuminating those activities most susceptible to time deviations. This approach is particularly valuable for project managers and engineers operating under high uncertainty, enabling proactive risk management and reducing potential bottlenecks
NARRAZIONI IDENTITARIE. Teorie e analisi nella letteratura del secondo millennio
No full textQuesto studio propone una lettura comparata di alcune opere selezionate di Rachel Cusk, Eshkol Nevo, Sally Rooney, Olivia Laing, Nina Bouraoui e Ocean Vuong, sei voci narrative contemporanee che, attraverso configurazioni testuali ibride – e, in alcuni casi, autofinzionali –, interrogano i confini tra esperienza vissuta e mediazione discorsiva, tra autenticità e costruzione letteraria.
Integrando le prospettive della narratologia cognitiva, della teoria dell’autofiction, degli studi queer e postcoloniali, le analisi mostrano come il sé narrante emerga da una continua negoziazione tra passato e presente, tra il bisogno di coerenza e la consapevolezza della trasformazione. L’identità, anziché costituire un’origine da svelare, si configura come un atto narrativo in divenire: relazionale, mobile, e profondamente generativo

No full textIntroducing a Digital Twin through Action Research: challenges and lessons learned
No full textThe advent of Industry 4.0 has led to the diffusion of advanced technologies such as the Digital Twin (DT). Adopting a DT may provide organisations with several benefits, including the ability to perform real-time monitoring and offline simulation. However, developing a DT and integrating it with an existing system come with several challenges, and it is not a straightforward process. To this end, scholars have been proposing several approaches and frameworks to facilitate the adoption of DT. Despite these efforts, a literature-practice gap often remains when introducing new technologies in a real industrial context, as seen in other fields. This gap can be due to scholars’ lack of practical experience, leading them to perceive different or less relevant challenges compared to practitioners. Few studies have investigated empirical challenges hindering the adoption of a DT, mainly outside of intralogistics activities. This paper wants to fill this gap by presenting an Action Research (AR) related to the development of a DT for an Automated Storage and Retrieval System (ASRS). The AR proved to be an effective method to introduce a DT in a real industrial context, enabling to transfer the academic knowledge to the organisation and let scholars experience the challenges and issues that must be addressed. The AR revealed that, despite a clearly stated objective, new requirements emerged along the way causing delays. Delays were also caused by lack of information, which the organisation was taken for granted and low compatibility data formats coming from different IT systems. This study and its outcomes can be exploited by scholars and industrial organisations that want to adopt a DT
Airborne microplastics: a Trojan horse for respiratory dysfunction and multiorgan damage
No full textMicroplastics (MPs), a class of pollutants, have emerged as a global challenge impacting both ecosystems and human health. Over recent decades, extensive research has been conducted to assess their presence across aquatic, terrestrial, and atmospheric environments. The pervasive accumulation of MPs, resulting from both excessive plastic consumption and inefficient waste management, has established ingestion (via the food chain) and inhalation (via ambient air) as primary routes of human exposure. While numerous studies have investigated the effects of ingested MPs, research on inhaled particles and their respiratory system impacts remains comparatively limited. Owing to their diminutive size, with MPs ranging from 1 μm to 5 mm and Nanoplastics (NPs) being smaller than 1 μm, they can penetrate bronchioles and pulmonary alveoli, eliciting both localized effects (e.g., inflammatory responses, oxidative stress) and systemic consequences. Notably, studies demonstrate that MPs can traverse the Blood-Brain Barrier (BBB), inducing neurotoxic effects. This review provides an overview of MPs' environmental impact and their documented effects on major human organs and tissues, with a focused analysis on the respiratory system. Specifically, we evaluate epidemiological studies and in vitro experimental models employed to elucidate the mechanisms by which MPs may contribute to chronic respiratory disease pathogenesis
Beyond Performance. A Critical Perspective on Education in a Private College
No full textThe study investigates the importance of balanced training that integrates theory and practice to improve students’ employability, within the geographic context of north-eastern Italy and the specific case of IUSVE, a private Salesian institute. It employs a qualitative methodology (35 in-depth interviews, 4 focus groups) to examine the meanings that students, faculty, and companies attribute to two specific three-year degree programmes aimed at professionalization: Advertising & Marketing and Digital & Graphic Design. The participants reported that a general cultural background built during undergraduate studies is important, but not central. The university cultivates well-rounded individuals by foster-ing critical thinking through the exploration of disciplines beyond immediate vocational applications. Thus, the university’s social value is primarily associated with its ability to provide adequate responses to open, dynamic, and rapidly changing scenarios by educating professionals to play roles that are not merely executive. This implies that, while emphasising employability, the university should not reduce itself to responding exclusively to the needs of the corporate world but should continue to support its broader role in promoting social responsibility and developing students’ critical capabilities
