Abstract
This article proposes an innovative integrated power and hydrogen distribution system (IPHDS) restoration model in response to multiple outages caused by natural disasters. During the restoration, repair crews and mobile battery-carried vehicles are considered to repair faulted lines and support critical power loads. Also, the network reconfiguration is taken into consideration in the restoration model to pick up loads. Besides, to address the different response time of hydrogen and power systems, the aerodynamic law-based dynamic hydrogen flow model is applied in the hydrogen system. The proposed model is presented as a mixed-integer linear program, which is verified on a 33-bus-48-node IPHDS with multiple outages. The present results verify the effectiveness of the proposed method.

Abstract
The concern about sustainability is growing and the Mediterranean diet has been extensively identified as a promising model, with benefits for human and environmental health. This systematic review aims to identify and describe the indicators that have been used to evaluate the sustainability of the Mediterranean diet and the results from their application. A methodology using PRISMA guidelines was followed, and searches were performed in Web of Science, PubMed, Scopus, and GreenFile. A total of 32 studies assessing the sustainability of the Mediterranean diet were identified. Twenty-five of these studies quantified the environmental impact, 7 studies evaluated the nutritional quality, and 12 studies assessed the daily cost of this dietary pattern. A total of 33 distinct indicators were identified, of which 10 were used to assess the environmental dimension (mainly, carbon, water, and ecological footprint), 8 were used to assess the nutritional dimension (mainly Health score and Nutrient Rich Food Index), 1 was used to assess the economic dimension (dietary cost), and 8 used combined indicators. The remaining 6 indicators for the assessment of sociocultural dimension were only identified in 1 study but were not measured. The Mediterranean diet had a lower environmental impact than Western diets and showed a carbon footprint between 0.9 and 6.88 kg CO2/d per capita, a water footprint between 600 and 5280 m(3)/d per capita, and an ecological footprint between 2.8 and 53.42 m(2)/d per capita. With regard to the nutritional dimension, the Mediterranean diet had a high nutritional quality and obtained 122 points on the Health score and ranged between 12.95 and 90.6 points on the Nutrient Rich Food Index. The cost of the Mediterranean diet is similar to other diets and varied between 3.33 and 14.42euro/d per capita. These findings show that no uniformity in assessing the MDiet's sustainability exists. Statement of Significance: Although several articles have presented the Mediterranean diet (MDiet) as a sustainable diet, it is not clear how this sustainability is being assessed by different authors. This systematic literature review aims to fill this gap, by identifying and describing the indicators used to evaluate the sustainability of the MDiet, taking into account the several sustainability dimensions and looking at the results from their application.

Abstract
To identify the most developed terms in the field of Tourism and virtual reality, a quantitative analysis was developed in February 2020. This analysis was focused on seven hundred and eighty-four (784) publications from the Scopus database, published between 1995 and February 2022 and limited to the following areas: Business Management and Accounting, Computer Science, Social Sciences and Engineering. A bibliometric analysis was performed using the VOSviewer software and a technique of matching terms and co-authoring by authors and countries. Were found 5 clusters for the co-occurrence of terms and 7 clusters for the co-authorship of authors and countries.

Abstract
Objective: We aim to answer four questions. First, with the increasing number of publications, is there a concentration in specific subjects, or on the contrary, a dispersion, amplifying the span of themes related to entrepreneurship? Second, is there a hierarchy of subjects, in the sense that some of them constitute the “core” of entrepreneurship? Third, are they connected with other established research areas? Finally, it is possible to identify papers that are influential, acting as hubs in the cluster’s formation? Method: We developed an original version of the computational procedure proposed by Shibata et al (2008), which allows us to understand the diversity of the different sub-areas of the topic investigated, reducing the need for specialist supervision. Originality/Relevance: We developed and applied a method to capture the formation and evolution of research areas in entrepreneurship literature, via direct citation networks, allowing us to understand the iteration between the different research sub-areas. Results: The dispersion is a feature of entrepreneurship as field research, with a hierarchy between research areas, indicating an emergent organization in the expansion processes. We concluded that research on entrepreneurship consists of specialization, that is, by application in niches. © 2022, Associacao Nacional de Estudos em Empreendedorismo e Gestao de Pequenas Empresas - ANEGEPE.

Abstract
Currently, humanity faces major challenges, namely in terms of energy production, consumption and management, in which electrical engineering should play a relevant role in the search for sustainable solutions. This training area is essential for industrial and economic development, and is therefore associated with economic competitiveness. However, demand for electrical engineering programs is decreasing, despite continuing to be a professional area with high employability. In view of this, it is important to try to understand the motivations and expectations that lead students to apply for programs in the field of electrical engineering. Thus, this study aimed to understand and analyse the motivations and expectations that led students from a Portuguese Polytechnic higher education institution to choose the field of electrical engineering. To this end, a questionnaire survey was used to collect the students' perceptions about why they chose this area, their expectations about their future professional activity, as well as about the role they attribute to engineering. The results show that students highly value the fact that it is a broadband area, with high employability and a wide variety of potential professional activities. Regarding the professional activity that students would like to pursue, the results stand out in the areas of renewable energies, the automobile industry, and electrical installations. The students' perception of the engineering's role reflects a generalized view that its objective is to improve the living conditions of humanity. However, some answers indicate a restricted perception of a technical character (it serves to make projects, calculations). The results obtained help to understand the profile and expectations of students who choose the field of electrical engineering, potentially contributing for the higher education institutions: i) to promote actions with the aim of enhancing the attractiveness of this area of knowledge; ii) to adapt their programs to the expectations of students and thus reduce academic dropouts or failure.

Abstract
Tor is the most popular anonymity network in the world. It relies on advanced security and obfuscation techniques to ensure the privacy of its users and free access to the Internet. However, the investigation of traffic correlation attacks against Tor Onion Services (OSes) has been relatively overlooked in the literature. In particular, determining whether it is possible to emulate a global passive adversary capable of deanonymizing the IP addresses of both the Tor OSes and of the clients accessing them has remained, so far, an open question. In this paper, we present ongoing work toward addressing this question and reveal some preliminary results on a scalable traffic correlation attack that can potentially be used to deanonymize Tor OS sessions. Our attack is based on a distributed architecture involving a group of colluding ISPs from across the world. After collecting Tor traffic samples at multiple vantage points, ISPs can run them through a pipeline where several stages of traffic classifiers employ complementary techniques that result in the deanonymization of OS sessions with high confidence (i.e., low false positives). We have responsibly disclosed our early results with the Tor Project team and are currently working not only on improving the effectiveness of our attack but also on developing countermeasures to preserve Tor users' privacy.
