- TRACENET: a VR framework to support online collaborative training activitiesPublication . Rigon, Simone; Perda, Giulio; Farella, Elisa Mariarosaria; Battisti, Roberto; Remondino, Fabio; Reis, Vitor; Marchesi, Silvia; Vaccari, Paolo; Wran-Schumer, DavidThe article introduces the VR framework and the preliminary outcomes of the ongoing European TRACENET project, an interdisciplinary and collaborative initiative to support and enhance Civil Protection training activities through 3D geospatial data and VR solutions. The VR framework is a virtual and collaborative multi-player environment for manifold and diverse hazard simulations which allows remote users to see the outcomes of their intervention decisions. The VR framework is a complementary solution to traditional training activities, enabling cost reduction of full-scale on-site exercises - included in so-called EU MODEX activities. The framework is based on the Unreal rendering engine and is primarily dedicated to situation assessment, intervention planning and decision making.

- Circular economy and sustainability in luxury fashion consumer behavior: a review and research agendaPublication . Gasulla Tortajada, Elena; Moreira, Antonio; Duarte, Paulo; Silva, Susana C.Over the last decade, luxury consumers have become more aware of the adverse environmental impacts associated with their lifestyles and are transitioning toward more responsible consumption patterns. Circular economy and sustainability business strategies have become crucial for this and have attracted the attention of scholars and brands. This paper aims to assess the current state of research concerning the circular economy and sustainability within luxury fashion consumer behavior. It focuses on relevant studies published in leading peer-reviewed English-language journals in business, management, and economics, using keywords such as luxury, consumer, circular economy, and sustainability. This review emphasizes the substantial impact of the 9Rs of the circular economy on luxury fashion consumers while also noticing the lack of consumer-focused research in the areas of the circular economy and sustainability. It presents a critical and thorough assessment, categorization, and analysis of the emerging literature in this field. The authors propose a deeper and more specific research agenda exploring the relationship between the circular economy, sustainability, and luxury fashion. The paper suggests potential directions for future research, emphasizing the need for theoretical, educational, and communication-oriented studies to address the distinctive circular economy and sustainability issues within luxury fashion consumption.
- Innovation capabilities and their dimensions: a systematic literature reviewPublication . Moreira, Antonio; Navaia, Eurico; Ribau, CláudiaInnovation capabilities (ICs) represent a crucial source of competitive advantage for firms. However, the literature on ICs is extensive, leading to a diverse understanding of their nature and measurement. A notable gap exists in delineating the dimensions constituting ICs. This article aims to address this gap by identifying and pinpointing the various dimensions of ICs through a systematic literature review (SLR). The initial step involves identifying the diverse dimensions used in ICs, providing a distinctive insight for assessing their metrics. Notably, this SLR stands out as the only comprehensive analysis of various ICs dimensions, organizing them coherently. Examining 103 articles from the Web of Science and Scopus databases spanning from 2001 to 2022, the results reveal an amalgam of scales and associated approaches for IC measurement. This study contributes to the literature by systematically identifying and analyzing the main dimensions employed by researchers to measure ICs. Additionally, it highlights the foundational theoretical approaches of the identified studies. In practical terms, the study consolidates and presents the identified dimensions and metrics in integrative tables, offering researchers and companies valuable insights into diverse innovation paths that impact performance.

- The interplay of bottle storage and wood ageing technology: volatile and sensory profiles of wine spirits aged with chestnut woodPublication . Anjos, Ofélia; Caldeira, Ilda; Vitória, Cláudia; Alves, Sheila Oliveira; Fernandes, Tiago; Canas, Sara; Catarino, SofiaWine spirits are typically aged in wooden barrels. Recently, alternative ageing technologies, such as those using wood fragments in wine spirits stored in stainless steel tanks, have been investigated. However, a signifcant lack of information regarding the potential evolution of these beverages after bottling still remains. This study assessed the 12-month evolu tion of aroma in bottled wine spirits aged with chestnut wood using diferent technologies, including fragment application with several micro-oxygenation strategies and barrels (traditional). Chemical analysis using GC-FID and GC–MS methods, along with sensory analysis, was conducted on all sampled aged wine spirits. Signifcant changes in volatile compounds were detected over time, including volatile phenols, acids, and esters. Multivariate data analysis distinguished traditional and alternative aged samples, with slight sample discrimination based on bottle storage. Regarding the sensory results, a signifcant efect of the time in bottle in several sensory attributes was found, while the ageing technologies mainly afected the gustatory attributes. The tasters were also asked to rate the overall quality of the samples, which seems to be favoured by the time in the bottle. This initial assessment of the impact of 1 year of glass bottle storage on the volatile and sensory composition of aged wine spirits highlights that this stage must be considered as an additional technological factor in their production process. However, the diferences induced by the wood ageing technologies applied remained evident after 1 year of glass bottle storage.
- A lightweight ontology for enterprise architecture mining of API gateway logsPublication . Pinheiro, Carlos Roberto; Guerreiro, Sérgio Luís P. Duarte; São Mamede, HenriqueEnterprise Architecture (EA) is defined as a set of principles, methods, and models that support the design of organizational structures, expressing the different concerns of a company and its IT landscape, including processes, services, applications, and data. One role of EA management is to automate modeling tasks and maintain up-to-date EA models while reality changes. However, EA modeling still relies primarily on manual methods. Contributing to EA modeling automation, EA Mining is an approach that uses data mining techniques for EA modeling and management. It automatically captures existing information in operational databases to generate architectural models and views. This paper presents an ontology for EA Mining that focuses on generating architectural models from API gateway log files. An ontology defines the concepts and relationships among them to uniquely describe a domain of interest and specify the meaning of the terms. API Gateways are information technology components that serve as a facade between information systems and enterprise business partners. The ontology development methodology followed the SABiO process, whereas the Unified Foundational Ontology provided the foundations of the ontology and OntoUML, the ontology modeling language. An experiment in an e-commerce application scenario was conducted to evaluate the theoretical feasibility and applicability of the ontology. Automatic semantic and syntactic validation tools and semi-structured expert interviews were used to confirm the desired ontology properties. This study aims to contribute to the evolution of the knowledge base of EA Management.
