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
Italian adaptation and psychometric properties of the prejudice against immigrants scale (PAIS): assessment of validity, reliability, and measure invariance
Full text linkThe aim of the current study was to adapt and validate the Prejudice Against Immigrants Scale (PAIS) in the Italian context, based on the Prejudice Against Asylum Seekers Scale by Anderson (2018). The validity, reliability, and measurement invariance across gender, age, and educational levels of the scale were assessed through three sources, which involved 306 Italian individuals (Nmen = 151, 49.3%) between 18 and 60 years old. Both exploratory and confirmatory factor analyses (CFA) confirmed the two-factor solution of the original instrument by excluding two items, which were present in the previous validation study. The first factor is classical prejudice against immigrants, which maps onto theoretical derivations of classical and old-fashioned prejudices, whereas the second factor is conditional prejudice against immigrants, which maps onto theoretical derivations of subtle and modern prejudices. Findings of the multigroup CFAs demonstrated full configural and metric invariance and partial scalar invariance of the scale across gender, age, and educational level. The analyses confirmed that PAIS has high levels of reliability and criterion and construct validity, showing findings that are comparable to those of Anderson (2018). These results suggest that PAIS presents very good psychometric properties and could be considered a valid and reliable instrument to measure prejudice against immigrants, by enabling Italian researchers to detect both covert and more subtle forms of prejudice against immigrants. Limitations and further directions are discussed
Gender Typicality, Social Self-Efficacy, and Adjustment in Italian Sexual Minority Young Adults
No full textThe present study focuses on the relationship between gender typicality, social self-efficacy, and adjustment in a sample of 522 lesbian women, gay men, bisexual, and other non-heterosexual sexual orientation participants. Participants (78.2% women; M-age = 23.8, SD = 3.63) reported their similarity to same- and other-gender peers as a way to assess their gender typicality, social self-efficacy, satisfaction with life, and perceived social safeness. The Path Analysis model showed that - controlling for participants' gender and sexual orientation- higher same- and other-gender typicality was associated with higher perceived social safeness and higher satisfaction with life, both directly and indirectly through social self-efficacy. The present study contributed to the debate on gender studies by testing same and other gender typicality as independent dimensions of gender typicality in sexual minority young adults, focusing on positive adjustment. Furthermore, the results suggested the role of social self-efficacy as a critical mechanism in the association between gender typicality and sexual minority psychosocial adjustment
The impact of road accidents on hospital admissions and the potential of ADAS in containing health expenditure: Evidence from Piedmont data
No full textOn average, more than 3,600 people die every day on world's roads: road accidents result in over 1.3 million deaths and 50 million injuries annually, placing a significant burden on society and generating substantial economic costs for Governments and Regions, which are responsible for healthcare expenditures. This study proposes and applies a novel methodology aimed at quantifying the effects obtainable from the use of the Advanced Driver Assistance Systems (ADAS) on the base of a real case, in economic terms as well. The real case consists on the analysis of a very large dataset regarding public health and hospital admissions, made possible by the exceptional access to the internal database, available for this scope, of the Piedmont Region (IT). Unlike the decades that have passed, it is now conceivable to identify transport related technological solutions that make it possible to prevent, sometimes even avoid, road accidents or at least reduce their severity. These solutions can be identified in ADAS. In a nutshell, their aim is to create a protective layer that mitigates the risk of accidents or reduces their severity. This concept is analogous to the “onion diagram” used in the railway sector, where multiple layers of protection prevent a single failure from leading to an accident. In essence, ADAS aim to introduce the industrial concept of fail-safe into road transport, at least providing it with a pre-alert: safety has been so far delegated only to the driver's alertness, caution and dexterity. Through the selective analysis of the health costs linked to road accidents, it is possible to quantify the elements considered important for the choices of public decision-makers on both subjects of health and sustainable mobility: in the Piedmont region, the average cost of a hospitalization following a road accident in 2013 was significantly higher than a hospitalization due to general trauma and values have remained similar in the following years. In the same period, road accidents accounted for 15% of the total number of injuries due to trauma, which implies this share can be affected by the adoption of ADAS, so as analysed within this paper for the years 2017–2019, i.e. before the COVID-19 pandemic. The weight of road accidents on hospitalisation is quantified: on the base of a huge Italian database, the average costs of hospitalisation due to loss of control is quantified. The role of ADAS (Advanced Driver Assistance Systems) for reducing costs of hospitalisation emerges
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
