Anthropometric Linear Measurements of Female Athletes in the Italian National Athletic Teams
Full text linkAnthropometry is essential to understand the predisposition of an athlete to practice a specific sporting activity, to assess their fitness, and in association with functional parameters, to identify any correlations between their anthropometric profile and their sport performance. Here, we present the anthropometric profiles of athletes of the Italian national teams, who represented Italy in the 2019-2020 competitive season in the following sports: artistic (n=4) and rhythmic (n=12) gymnastics; distance swimming (speciality: 100 m freestyle) (n=14); synchronized swimming (n=10); and basketball (n=6). We also consider a group of sedentary women (n=22) for comparisons. The following anthropometric measurements were taken for each woman: stature; anterior trunk height (i.e., suprasternal-symphysion distance); chest circumference passing through the mesosternal point; biacromial diameter (i.e., akromion-akromion distance); wrist circumference; abdominal circumference passing through the omphalion and the lumbale; hip circumference; height of lower limb (i.e., epitrochanter-planta distance). Height was a selective factor in both basketball, which requires tall athletes, and artistic gymnastics, where in contrast, well-muscled athletes of small stature are required. In aquatic sports, the constitutional habitus is characterized by good development of the upper body compared to the lower limbs. The selection of elite athletes takes place primarily through anthropometric analyses, although other functional and psychological factors also influence their sports performance
The (dominance based) rough set approach applied to air pollution in a high risk rate industrial area
No full textThis study presents a Rough Set Analysis (RSA) application, partially based on dominance in relation to air micro-pollution management in an industrial place with a high environmental risk rate, such as the industrial area of Siracusa, located in the South of Italy. This new data analysis instrument has been applied to different decisional problems in various fields with considerable success. Therefore, it is believed that it could also be used for the environmental issue related to multi-attribute sorting, considering both qualitative and quantitative attributes and criteria, such as sulphur oxides (SOx), nitrogen oxides (NOx), Methane (CH4), nonmethane hydrocarbons (NMCH) and some meteorological variables, such as air temperature and the relative humidity index. After outlining some basic concepts of the RSA theory, the most significant results obtained from the RSA specific application are presented and discussed particularly examples of decisional rules, attribute relevance and some other methodological features are offered to improve understanding and advantages of the approach. The decisional rules obtained can also be usefully implemented in order to explain and manage the risk of air pollution
Freight transport in the context of industrial ecology and sustainability: evaluation of uni- and multi-modality scenarios via life cycle assessment
No full textPurpose: This study aims at comparing, from an environmental point of view, four different scenarios of freight transport at the Italian level, on an equal base of route between supplier and customer. The first scenario included freight movements by truck and mainly ship, the second included track and mainly train, the third was the three-modal based scenario, whilst the fourth scenario was the only uni-modal, based only upon truck movement. The study was conducted to find the environmentally sustainable solution, or at least a sustainable trade-off, as well as the most environmentally burdening issues, associated with the geographic dimension of transport in Italy, towards sustainability. Methods: Using uni‐ and multi-modal freight movements by truck, rail and ship, a life cycle assessment (LCA) was developed to estimate the related environmental burdens both at the midpoint and at the endpoint levels from the consumption of primary energy and natural resources along with the emissions of greenhouse gases (GHGs) and of other pollutants. Primary data were compiled as part of the inventory analysis and consisted in the transport flows associated with the system investigated: those were calculated from the distance travelled and the goods load transported. Primary data were then combined with secondary data that were modelled with the transport life cycle modules contained in Ecoinvent: from those modules, the fuel consumption amounts associated transport flows were extrapolated, and used for the assessment. Results: Results showed that the environmental impact of the multi-modal scenarios is lower compared with the uni-modal scenario. The best performing option was found to be the third scenario providing use of all the three freight means, namely ship, train and truck. However, this scenario is not being practiced for several reasons, mainly due to control and monitoring difficulties of each step and higher operational costs. The first and second scenarios showed a quite comparable environmental behaviour and so are to be considered as viable options. Conclusions: Apart from highlighting the most environmentally viable transport options, the study contributed to finding the indicators of environmental impact and damage that best describe the system investigated and are recommended by this author team to be accounted for in future assessments in the transport sector. Finally, although site-specific, the results of this study may be useful to logistics companies, policy and decision makers of other regions and countries towards identifying and promoting environmentally optimal freight transport solutions, contributing to sustainability of the transport sector

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
Corporate eco-efficiency and financial performance
No full textCorporate social responsibility (“CSR” for short) is a form of corporate self-regulation integrated into a business model. CSR policy functions as a mechanism whereby business monitors and ensures its active compliance with the respect of the law, ethical standards, and international norms. The goal of CSR is to embrace responsibility for the company’s actions and encourage a positive impact through its activities on the environment, consumers, employees, communities, stakeholders and all other members of the public sphere. In this paper the environmental aspect of CSR for the highest relevance in corporate governance and policy will be put in focus, and it can be synthesized in the “environmental social governance” concept. Particularly, a very interesting approach, analysed in this work, is concerning the link between CRS in environmental governance and corporate success, which could result in financial returns, in fair stock pricing, in a higher asset value, in efficient portfolio investment, in pricing firm equity, and so on – roughly speaking – in capital investment and in all financial and economic activity of the companies for satisfying shareholders. In order to establish the internal drivers of environmental performance, are usually selected a number of indicators that better reflect the characteristics of the enterprises and their environmental and financial performances, such as profitability, costs, size, energy consumption, efficiency, potential pollution and risk
Why hybrid composite materials? Findings from a systematic literature review of life cycle assessments
No full textThe article explores the relevant environmental issues of hybrid composite materials, that are defined as those systems in which two reinforcing or filling materials are added to a matrix, or a reinforcement or filler is added to a blend of matrices. To that end, a systematic literature review of Life Cycle Assessments (LCAs) in the field was carried out by the authors according to the PRISMA model, given that LCA is internationally recognized to be a scientifically-based valid methodology for assessing and improving sustainability issues of products and services. Web of Science (WoS) and Scopus were used to perform the bibliographical search, those are globally recognized to be the most comprehensive databases of peer-reviewed journals and, so, to store the broadest range of scientific articles. The analysis of literature on the field of the lifecycle assessment (LCA) of hybrid materials have shown that this is a new path still to be explored. While LCA is widely used for the assessment of environmental properties of different materials and applications, to date only few papers apply this methodology to assess the lifecycle of hybrid materials. Results retrieved have been combined to obtain the core works assessed in this review, finding that currently the literature about the application of LCA methodologies for assessing the impacts of hybrid composites is very limited, with not many references found to date, and thus there is huge potential for future growing in this path
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
