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
Beliefs and Perceptions in Attending the Cervical Screening: The COMUNISS Project Experience
No full textBackground: Several studies highlighted that tailored health communication interventions improve cervical screening participation, vaccination coverage, and awareness about self-sampling benefits. The “COMUNISS” project was aimed at increasing awareness about cervical cancer prevention, identifying barriers to screening, and promoting screening uptake in under-screened women. Methods: A dedicated website with a Q&A session regarding HPV-associated diseases has been set up. Participants were invited to complete a questionnaire to gather demographic information, knowledge about HPV and cervical cancer, and attitudes toward screening based on the Health Beliefs Model (HBM). Women can also require a vaginal self-sampling kit at your home to perform the HPV-DNA analysis. Results: The website registered over 1000 users over 6 months, and 256 women completed the survey. Nearly half were under-screened. The HBM revealed a high susceptibility and severity perception of diseases, regardless of screening participation, whereas older women declared a high perception of barriers. One-quarter of the women who had requested the self-collection kit returned it for the HPV-DNA testing. Conclusions: The project found significant gaps in knowledge regarding extra-cervical HPV-related cancers, interpretation of screening results, and effectiveness of self-collection. These findings highlight the need to plan targeted information campaigns to enhance awareness and adherence to screening programs
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
Nursing students' clinical competencies: a survey on clinical education objectives
Full text linkDeveloping clearly defined competencies and identifying strategies for their measurement remain unfortunately a critical aspect of nursing training. In the current international context, which continues to be characterised by deep economic crisis, universities have a fundamental role to play in redefining the educational goals to respond to the expectations of certain geographical areas of interest, as underscored in the Bologna Process (Joint Declaration of the European Ministers of Education Convened in Bologna 19 June 1999)
Cardiorespiratory fitness assessment using the PREFIT test in Italian children: A preliminary dataset
No full textBACKGROUND: The cardiorespiratory fitness (CRF) is one of the most important indicators of the health-related physical fitness components because it reflects the efficiency of the cardiovascular and respiratory systems. To indirectly assess CRF, the original protocol of the 20mSRT was adapted in a new version suitable for children called 20mSRT-PREFIT, providing performances comparable to the standards of the European area. In fact, CRF normative values are missing in the Italian context and therefore they would be meaningful to be assessed. We aimed to determine CRF from 20mSRT-PREFIT in a small sample of Italian pre-school children and to compare the outcomes with the available European references. METHODS: A convenience sample of 5-year-old pre-school children (N.=32, M/F ratio: 19/13) was freely recruited from a kindergarten of the northwest Italy. Children performed the 20mSRT-PREFIT and the number of full shuttles, exhaustion time, and maximum speed were collected to obtain CRF. RESULTS: Predicted VO2max was similar between Italian male and female groups. All other outcomes originating from the 20mSRT-PREFIT were consistent with those included in the available European databases. CONCLUSIONS: According to these preliminary indications, Italian pre-school children may have a CRF level equivalent to that one ascertained in other European countries. Thus, current rakings should be cautiously scrutinized, as they might inappropriately underrate Italian children’s performances
Apical periodontitis in inflammatory bowel disease: a meta-analysis at patient and tooth level
No full textApical periodontitis (AP) is the local inflammation of periapical tissues originating from the dental pulp disease. Cumulative evidence suggests a link between oral and gastro-intestinal systems in both health and disease. In this context, the relationship between AP and inflammatory bowel diseases (IBDs) has not yet been elucidated. The aims of this systematic review and meta-analysis were to describe the prevalence of AP in patients with IBDs and evaluate the potential association between AP and IBDs. Electronic (Embase, PubMed, Scopus, Web of Science) and manual literature searches were conducted from inception to 31 October, 2023 (updated in August, 2024). Strict inclusion criteria were applied to identify observational and experimental clinical studies on AP in IBDs patients. The bias risk was assessed using the Joanna Briggs Institute critical appraisal tools and a biases' report selected from the Oxford Centre for Evidence Based Medicine Catalogue of Bias. A meta-analysis was performed to determine the pooled prevalence and risk of AP at individual and tooth level and the quality of evidence was assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The search strategy identified 82 articles with 5 studies included (657 subjects, 7,142 teeth). The overall proportion of AP was 58% at patient level (95% CI = 37%–78%, I2 = 95.3%) and 7% at tooth level (95% CI = 2%–15%; I2 = 99.2%). AP was prevalent in IBDs subjects than in healthy controls, both at patient and tooth level. The pooled OR was 1.57 (95% CI = 1.04–2.35; P = 0.038; I2 = 20%) at patient level, and 1.91 (95% CI = 1.16–3.15; P = 0.011; I2 = 82%) at tooth level. A potential association between AP and IBDs is plausible, although the quality evidence was low to very low. Longitudinal and experimental studies should be conducted to better understand the relationship between these two conditions and explore any potential causative factors.
