No full textSustainable Tourism in Campania Region: Statistical Analysis and Metrics for the Development of Tourist Destinations
Full text linkThis paper deals with the issue of the sustainable tourism in Campania region and its touristic offer in the four territorial clusters: art cities, marine, thermal and hilly locations. In the paper it is pointed out that the way the regional authorities incentivize or assist touristic firms to diversify into tourism may have implications for sustainability. In this work we measured the potential of tourism by the aggregation of 11 indicators. In this study was estimated by the Global Tourism Index (G) for the region and for the four territorial areas (cluster), obtained from the combination of structural variables (number of accommodation facilities and of beds) and of flows (arrivals and presences) registered in Campania tourism. Finally, some emerging territorial strategies are proposed for the integrated development of a tourist system in the Campania Region. That is, the tourist destinations and the territorial brand. The final aim of this research is to develop and test a new Global Index for evaluating the sustainable development in tourism industry context to address the integration of social, economic, and ecological elements of sustainable development
End-of-life management of oil and gas offshore platforms: challenges and opportunities for sustainable decommissioning
No full textPurpose of the paper: The decommissioning of offshore platforms represents a significant and controversial challenge that has gained attention over the years due to its environmental, social, and economic impact. This work aims to investigate stakeholders’ perceptions regarding the future of offshore platforms and to explore dimensions of sustainability related to decommissioning.
Methodology: An analysis was carried out based on two rounds of empirical inquiry, a range of primary data collected through multiple-choice questionnaires and in-depth interviews.
Findings: The analysis shows that stakeholders perceive reuse as an opportunity to minimise the impacts according to an environmental, economic, and social perspective. While the multipurpose platform represents an opportunity for the future, it also presents challenges.
Research limitations: The study relies only on qualitative analysis techniques and on a limited sample and geographical area.
Practical implications: The analysis offers several insights into the decommissioning scenario according to a sustainable and circularity perspective and contributes to the decommissioning debate by providing information about decommissioning programs, stakeholders’ impacts, and future planning considerations.
Originality of the paper: The study contributes knowledge to the field and useful managerial insights, highlighting stakeholders’ perception in the Italian context and exploring dimensions of sustainability and main SDGs related to the issu
Change My Mind: how Syntax-based Hate Speech Recognizer can Uncover Hidden Motivations based on Different Viewpoints
No full textHate speech recognizers may mislabel sentences by not considering the different opinions that society has on selected topics. In this paper, we show how explainable machine learning models based on syntax can help to understand the motivations that induce a sentence to be offensive to a certain demographic group. To explore this hypothesis, we use several syntax-based neural networks, which are equipped with syntax heat analysis trees used as a post-hoc explanation of the classifications and a dataset annotated by two different groups having dissimilar cultural backgrounds. Using particular contrasting trees, we compared the results and showed the differences. The results show how the keywords that make a sentence offensive depend on the cultural background of the annotators and how this differs in different fields. In addition, the syntactic activations show how even the sub-trees are very relevant in the classification phase
How dramatic events can affect emotionality in social posting: The impact of covid-19 on reddit
Full text linkThe COVID-19 outbreak impacted almost all the aspects of ordinary life. In this context, social networks quickly started playing the role of a sounding board for the content produced by people. Studying how dramatic events affect the way people interact with each other and react to poorly known situations is recognized as a relevant research task. Since automatically identifying country-based COVID-19 social posts on generalized social networks, like Twitter and Facebook, is a difficult task, in this work we concentrate on Reddit megathreads, which provide a unique opportunity to study focused reactions of people by both topic and country. We analyze specific reactions and we compare them with a “normal” period, not affected by the pandemic; in particular, we consider structural variations in social posting behavior, emotional reactions under the Plutchik model of basic emotions, and emotional reactions under unconventional emotions, such as skepticism, particularly relevant in the COVID-19 context
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
