Girls4STEM: Gender Diversity in STEM for a Sustainable Future
2020
Science, Technology, Engineering, and Mathematics (STEM) are key disciplines towards tackling the challenges related to the Sustainable Development Goals. However, evidence shows that women are enrolling in these disciplines in a smaller percentage than men, especially in Engineering related fields. As stated by the United Nations Women section, increasing the number of women studying and working in STEM fields is fundamental towards achieving better solutions to the global challenges, since the potential for innovation is larger. In this paper, we present the Girls4STEM project, which started in 2019 at the Escola Tè
Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists
2018
The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…

2020
This study examines the effect of online social talent on business performance. The paper uses data from a selected sample of 296 companies from the S&
Social Determinants of Success: Social Media, Corporate Governance and Revenue
2019
This study examined how social media (Twitter and LinkedIn) relates to the operating revenue by investigating the effect of the use of social media by the board of directors. To tackle this question, we analyzed the mediating and moderating relationship of social media on the effect of board size in operating revenue (turnover). We studied the implications of the use of social media by the board members by using structural equation modeling (SEM). The data consisted of a random sample of 100 companies listed on the NASDAQ. The study makes two main contributions. First, it shows interesting differences in the use of social media for the operating revenue. Our results suggest that while Twitt…
Audit Institutions in the European Union: Public Service Promotion, Environmental Engagement and COVID Crisis Communication through Social Media
2020
This article analyses Social Media (SM) use as a promotion tool for public institutions in the public audit sector. The authors propose a quantitative model to assess online engagement of 94 European audit institutions (national and regional) with their stakeholders, based on SM and web activity metrics of these institutions, with a focus on pressing matters such as environment, sustainability and the current COVID pandemic. The proposed model may be applied to assess organisations from any public or private sector. The research finds that SM presence helps audit institutions to promote their services more effectively by directing their stakeholders to extensive content on the audit institu…
Disability in Older People and Socio-Economic Deprivation in Italy: Effects on the Care Burden and System Resources
2021
The sustainability of European Long-Term Care systems faces the demographic and socio-economic circumstances, mainly the increasing ageing of the population, with its chronic disease conditions, and the simultaneous economic general crises, exacerbated by the recent COVID-19 pandemic. Beyond the increase in general rate of relative poverty, there is a higher risk of poverty among elderly and families in a high demand of care, especially if situations of Activities Daily Living (ADL) disability are present. Italian welfare, which is based on family care regimes and regional strategies, and is oriented to private or public care, is a relevant case study with which to analyze such a relationsh…
Long-Term Educational Sustainability: Educational Innovation in Social Vulnerability Contexts
2017
This paper investigates the behavior of children from low socioeconomic status families and examines the effects of a socioemotional education program on aggression in children. The results of the program are compared according to the children’s gender and age, the family structure, the parents’ educational attainment, and social status. The results show that applying socioemotional education programs reduces children’s aggression and encourages positive development during adolescence. This positive development fosters open, expressive behavior.
Postępy w fotowoltanice w Polsce i na świecie = Progress in photovoltaics in Poland and the world
2015
W artykule przedstawiono postęp w zakresie uzyskiwanych sprawności przez ogniwa i moduły fotowoltaiczne (PV) wykonane z różnych materiałów i za pomocą różnych technologii. Zawarto w nim szczegółowe zestawienia tabelaryczne sprawności oraz ich parametrów technicznych. Zwrócono uwagę na nowe obiecujące technologie, które jeszcze nie mają rekordowych sprawności, ale z uwagi na proces ich wytwarzania rokują nadzieje na uzyskanie bardzo dużych sprawności albo tanich wielkopowierzchniowych modułów do komercyjnego zastosowania. Ponadto, omówiono ekonomiczne skutki wdrożenia nowo zawartych zapisów w uchwalonej w lutym 2015 r. Ustawie o Odnawialnych Źródłach Energii (OZE) dla rozwoju rozproszonych i…
Re-Inhabiting Inner Areas Triggering New Regeneration Trajectories: The Case Study of Sicani in Sicily
2022
The Italian debate on the so-called ‘inner areas’ has received a much-needed boost, following the COVID-19 pandemic, which has further highlighted the differences between metropolitan and inner areas. While the progressive depopulation of inner areas is a worrying phenomenon, the limits of incessant urbanisation and the concentration of settlement and infrastructure policies in large conurbations have become evident. Departing from the framework of the B4R-Branding4Resilience research project of national interest and, by continuing in the furrow initiated by the SNAI, but also surpassing it, the aim of the University of Palermo’s research is to define the requirement for a…
Preliminary Evaluation of Plasmix Compound from Plastics Packaging Waste for Reuse in Bituminous Pavements
2021
Finding an appropriate technical solution for reusing waste plastics is crucial for creating a circular plastic economy. Although mechanical recycling is the best option for recycling post-consumer plastics, some heterogeneous mixed plastics cannot be recycled to produce secondary material due to their very low properties. In this case, alternative routes should be considered in order to limit their disposal as much as possible. Therefore, in order to solve the environmental problems in the landfills of plastic waste recycling, and to improve the mechanical performance of bitumen for road pavement, the reuse of these post-consumer plastic wastes are preliminarily evaluated for the modificat…
