Prendersi Cura: Re-immaginare Spazi e Relazioni in prospettiva indigena e femminista
No full textPrendersi Cura: Re-immaginare Spazi e Relazioni in prospettiva indigena e femminista è uno studio qualitativo, esplorativo, partecipativo condotto presso L’Università di Victoria (British Columbia, Canada). Parte dall’esplorazione delle dimensioni e delle rappresentazioni sociali sottese all’area del Care (prendersi cura di noi stessi, degli altri, del mondo) indagando il rapporto tra cura e femminile da un lato, e tra cura e giustizia sociale dall’altro. In una fase successiva, la ricerca si è focalizzata sull’esplorazione e la co-costruzione di pratiche di cura relazionale nel contesto universitario, integrando approcci femministi, pratiche artistiche e prospettive indigene, al fine di trasformare gli spazi educativi in luoghi più attenti alla corporeità, al benessere psicofisico e alle relazioni. Lo studio combina ricerca-azione partecipativa e auto etnografia e comprende l’analisi dei prodotti artistici realizzati durante sessioni di workshop condotti con studenti dei corsi di laurea triennale, magistrale, di dottorato e ricercatori/docenti. I partecipanti sono stati invitati ad esprimere le proprie emozioni sia individualmente che in modo collaborativo creando prodotti artistici che riflettono vissuti personali e collettivi sui temi legati alle dimensioni della cura, della salute mentale e della leadership. La content analysis restituisce un’analisi delle categorie di rappresentazione e discriminazione sociale usate dai partecipanti osservando ed esplicitando relazioni fra le rappresentazioni degli “agenti” e le loro pratiche e, allo stesso tempo, le strutture sociali in cui agiscono. L’indagine si è posta l’obiettivo di esplorare e attivare pratiche trasformative in grado di abitare gli spazi dell’apprendimento come luoghi di cura, dove l’immaginazione possa aprire varchi verso futuri educativi altri, prendendo in considerazione la complessità dei setting in tutte le loro dimensioni, visibili e invisibili.Taking Care: Re-imagining Spaces and Relationships from Indigenous and Feminist Perspectives is a qualitative, exploratory, and participatory study conducted at the University of Victoria (British Columbia, Canada). The study begins by examining the dimensions and social representations underlying the field of care, understood as caring for oneself, others, and the world, by investigating, on the one hand, the relationship between care and femininity, and on the other, the relationship between care and social justice. In a subsequent phase, the research focused on the exploration and co-construction of relational and embodied practices of care within the university context, integrating feminist approaches, art-based practices, and Indigenous methodologies grounded in principles of relational accountability and reciprocity. The aim was to transform educational spaces into environments more attentive to embodiment, psychophysical well-being, and relationality. The study combines participatory action research and autoethnography and includes the analysis of artistic artefacts produced during workshop sessions conducted with undergraduate, graduate, and doctoral students, as well as researchers and faculty members. Participants engaged in situated, affective, and collaborative meaning-making processes, expressing emotions both individually and collectively through the creation of artistic works reflecting personal and shared lived experiences related to care, mental health, and leadership. Content analysis provides an examination of the categories of social representation and social discrimination employed by participants, observing and explicating the relationships between the representations of social “agents,” their practices, and the social structures within which they operate. The study aimed to explore and activate transformative practices capable of inhabiting learning spaces as spaces of care, where imagination can open pathways toward alternative educational futures, while accounting for the complexity of educational settings in all their visible and invisible dimensions
A Study on Utilization of Mussel Shells in Cement Mortar: Enhancing Sustainability and Mechanical Properties
No full textThe construction sector faces huge pressure to adopt sustainable practices and reduce its environmental impact. This study explores the innovative use of mussel shells, a by-product of the seafood industry, silica fume and fly ash in cement mortar to enhance both sustainability and mechanical properties. Two important issues are addressed by the integration of these waste elements: efficient waste management and the creation of sustainable building materials. Mussel shells were processed by cleaning, oven dried at 60°C temperature for 24 h and grinded to achieve a suitable particle size for use as a partial replacement by weight of cement. Silica fume and fly ash, known for their pozzolanic properties, were used to partially replace sand. Various mix designs were prepared with different proportions of mussel shells (10%, 20%, 30%), silica fume (5%), and fly ash (5%). Mechanical tests, including compressive strength and flexural strength were conducted to evaluate the performance of the modified mortars after 7, 14 and 28 days. The results demonstrate that the combined use of mussel shells, silica fume, and fly ash significantly enhances the mechanical properties of cement mortar. Notably, the mix with 10% mussel shells, 5% silica fume, and 5% fly ash exhibited a remarkable increase in compressive and flexural strengths, achieving a 20% and 25% improvement, respectively, compared to the other mixes. In conclusion, the synergistic use of mussel shells, silica fume, and fly ash in cement mortar presents a promising approach to achieving sustainability and improved mechanical properties in construction materials. This research opens avenues for further exploration and optimization of alternative materials in the construction industry

On the effect of HVAC recirculation on thermal comfort and indoor air quality in train cabins
No full textMaintaining hygrothermal comfort and Indoor Air Quality (IAQ) in train cabins is crucial for the well-being of passengers and crew, particularly in mitigating the risks associated with airborne transmission. The Heating, Ventilation, and Air Conditioning (HVAC) systems play a critical role in determining airflow patterns, thermal comfort indices, and the distribution of airborne particles. This study investigates the effects of varying return air intake ratios, a practical and non-structural modification, using Computational Fluid Dynamics (CFD). Four HVAC configurations with different return air percentages (0 %, 25 %, 50 %, and 75 %) are assessed in terms of thermal comfort indices and the particles evacuation efficiency generated by a sneeze. The results reveal an optimal trade-off between thermal comfort and particle evacuation efficiency: low return intake (0 %) provides the best thermal comfort conditions; however, the optimal IAQ is achieved with a moderate return intake (50 %), which results in the highest particle evacuation rate (82.34 %) and significantly reduced particle deposition in critical areas, such as the seating zones. In contrast, a high return air intake (75 %) leads to recirculation zones that trap particles and hinder their removal, while a low return air intake increases the risk of particle deposition for passengers. This study underscores the importance of a multi-criteria approach in HVAC design for train cabins, emphasizing that configurations optimized solely for comfort may not ensure protection against airborne pollutants

No full textTowards Resilient Energy Systems: Protecting the Energy Supply Chain Against APTs
No full textThe current Electric Power and Energy Systems sector has been profoundly changed by the introduction of smart grid tech- nologies, which have completely reshaped the security measures for protecting energy infrastructure. While conventional power systems were characterized by centralized generation and uni- directional power flows, the emergence of distributed energy re- sources, renewable energy integration, and prosumer-based archi- tectures has introduced unprecedented complexities in the threat landscape. These evolutionary changes have not only expanded the attack surface of energy systems but have also introduced novel vulnerabilities that stem from the bidirectional nature of modern energy flows, the proliferation of Internet-of-Things de- vices at the grid edge, and the increasing reliance on information and communication technologies for operational control. The traditional security frameworks that were developed for legacy power systems prove inadequate when confronted with the multi- faceted threats inherent in these distributed, interconnected, and digitally-enabled energy ecosystems. Prosumer integration, in particular, has created numerous weak points throughout the in- frastructure, as residential and commercial entities equipped with distributed generation, storage systems, and smart devices be- come integral components of the broader energy network. These edge nodes, often characterized by limited security measures and inconsistent monitoring capabilities, represent critical vulnera- bilities that can be exploited to compromise the stability and integrity of the entire energy system. This research addresses these issues by first revealing a profound lack of governance and defined liability for security incidents originating from prosumer assets. It demonstrates that the cumulative threat from aggre- gated edge devices constitutes an overlooked systemic risk. In response, this thesis presents two key contributions. First, a specialized threat model and a reference APT scenario to guide future research. Second, a novel monitoring framework that use digital twin technology and data sovereignty principles. Results show that this approach effectively detects prosumer-based ma- licious activity, thereby securing the continuity of grid operations without compromising citizen privacy, offering a resilient founda- tion for securing the distributed energy perimeter
The emergence of innovation capabilities supporting technological shifts among SMEs: A mediated moderated model
No full textThe adoption of innovations to support technological transitions is widely recognized as a key strategic lever for
maintaining competitiveness, but while many studies have explored the general determinants of innovation, less
is known about the factors that foster the development of innovation capabilities (ICs)—those competencies that
enable a systematic approach to innovation. This knowledge gap is particularly evident in the context of small
and medium-sized enterprises (SMEs), despite the significant role they play in many national economies, so
understanding how SMEs can systematically pursue innovation is therefore crucial for the competitiveness of
these economies. To address this gap, this study proposes and tests an interpretative model aimed at predicting
the emergence of ICs within SMEs. The model examines how commonly studied determinants of innovation are
moderated by two specific antecedents: organizational tools and procedures. Using partial least squares structural equation modeling (PLS-SEM), the study analyzes a sample of innovation-oriented SMEs, with the results
showing that economic objectives, available resources, networking, and corporate culture influence SMEs’ decisions to invest in organizational tools and procedures that enhance ICs. In fact, organizational tools play a
central mediating role, while excessive procedural formalization may hinder flexibility and limit innovation
outcomes. This research contributes to clarifying the antecedents of ICs and offers theoretical, practical, and
policy insights that are applicable beyond the specific context investigated
