Exploring Quality of Life, Body Image and Sexual Satisfaction in Intersex Individuals: A Systematic Review and Meta-Analysis
No full textThis systematic review and meta-analysis aims to evaluate quality of life and body image among adolescents and adults with variations in sexual characteristics (VSC). It will analyse the experiences of intersex people and those with VSC concerning self-perception, psychological well-being, and overall quality of life at different life stages, with a focus on the relationship between body image and quality of life. A systematic search was conducted using the new Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Articles were retrieved from Scopus and Web of Science databases from January 2006 to August 2024. After identifying 1084 scientific articles, 26 studies were included. The data on quality of life indicate a trend similar to that of the general population. However, studies examining body image and sexual satisfaction reveal findings specific to the intersex population. This review shows that the variable of body image has a significant impact on intersex youth and adult individuals and those with VSC. Even though their responses vary, many individuals report dissatisfaction with sex-related body parts.
Understanding the impact that self-representation of one's body image has on sexual relationships and overall quality of life can support the development of new interventions aimed at developing a satisfactory body perception for intersex individuals. These interventions could help individuals experience their bodies more comfortably, thereby enhancing the overall well-being of intersex adolescents and adults and those with VSC
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
Polychlorinated biphenyls and organochlorine pesticides in European eel (Anguilla anguilla) from the Garigliano River (Campania region, Italy)
No full textMeasuring organochlorine compounds in muscle tissue of European eels from the Garigliano River in Campania (Italy), overall PCBs emerged as the most abundant pollutants, followed by DDTs, Dieldrin and HCB. Target PCBs, IUPAC nos. 118, 138, 153 and 180, were the dominant congeners accounting for 64.2% of total PCBs. Among OCPs, p,p'-DDE was detected in all eels, always with higher concentration levels than other OCPs; p,p'-DDT was frequently detected, about 93.3% of the sample. The high and statistically significant correlations between concentration and length as well as weight of eels suggest that the organochlorine compounds concentrations tend to increase with the size and consequently with the age. Concentrations of DDTs and PCBs detected were similar to those reported in studies relative to France, UK and Sweden. As regards toxicological risk for human health, in general OCPs residual levels were below the limits established for fish and aquatic products. Conversely, the concentrations of PCBs exceeded the limit set by the EU for terrestrial foods. Our results imply that OCPs and PCBs are still important persistent chemical contaminants in Campania freshwaters, although their manufacture and use are banned or highly restricted
Red foxes (Vulpes vulpes) bioindicator of lead and copper pollution in Sicily (Italy)
No full textThe aim of this study was to evaluate Pb and Cu accumulation in muscle and skin samples of red fox (Vulpes vulpes) from Sicily, for monitoring of environmental metals pollution. Metals determination, carried out by atomic absorption spectrophotometer (AAS), showed the presence of Pb and Cu in all samples analyzed. Pb concentrations were similar in muscle (0.04±0.009 mg/kg) and skin (0.03±0.004 mg/kg) samples, while Cu levels resulted higher in muscle (1.842±0.178 mg/kg) than in skin (1.22±0.151 mg/kg). In addition, a comparative analysis of Pb and Cu concentrations was carried out among samples from different areas of Sicily and between female and male, young and old, immature and mature foxes. Metals content found in all muscle and skin samples demonstrates that V. vulpes could be a valid ‘‘sentinel’’ species of rural and suburban areas to study the environmental metals pollution and the habitat quality
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
