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
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
Development and validation of an instrument to assess propensity to cosmopolitanism in adolescence
Full text linkThe study was designed to provide the initial validation of the instrument “How cosmopolitan do I think I am?" to assess the propensity to cosmopolitanism in adolescents interested in reflecting about their future career choices. Two studies were carried out to test psychometric requisites of the instrument “How cosmopolitan do I think I am?" Specifically, in the first study, after developing items and examining content validity, the factorial structure and the reliability of the scale were tested. The results showed good fit indexes for a factor structure characterized by threecorrelated factors and for a second order-factor structure. This last factor structure model suggests that three hypothesised factors can be considered indicators of a global dimension of cosmopolitanism. In the second study, discriminant validity was evaluated. The results confirmed that the three dimensions of cosmopolitanism are related but distinct from career adaptability (CA) and the tendency to consider systemic challenges to attain sustainable development (TCSC). Overall, the results observed supported the use of the questionnaire in career vocational guidance and counseling activities
Elementary school students’ attitudes towards peers with disabilities: The role of personal and contextual factors
No full textBackground: Attitudes of classmates has been considered as one of the major problems in inclusive education, negatively influencing the participation of students with disability in school contexts. The goal of this study was to examine Italian typically developing children's attitudes towards their peers with disabilities. Method: In a sample of 560 elementary school students aged 6 - 11 years old we tested - through multiple regression analysis - the impact of personal and contextual factors, such as sex and age of participants, type of disability of peers with disabilities, experience with peers with disabilities and, in particular, the type of presentation of students with disabilities on attitudes of elementary school students without disability. Results: Results showed that girls and younger students generally hold more positive attitudes towards peers with disabilities. Less accepting attitudes towards peers with behaviour problems than those with intellectual or sensory disabilities were also found. Experience with peers with disabilities in class was not related to attitudes towards disabilities; instead, providing a positive presentation of peers with disabilities associated with their strengths positively impacted attitudes towards disabilities, regardless of sex and age of participants and type of disability of peers. Conclusions: The results of our study suggested the impact of the type of information provided to students about disabilities on their attitudes. Particular emphasis should be given to the way in which children with disabilities are presented to typically developing classmates, and information provided should stimulate a positive image of peers with disabilities
Italian adolescents’ understandings of globalization
No full textIntroduction: Having a clear understanding of the concept of globalization can be particularly relevant for adolescents to comprehend how the world functions and to reflect on the way their personal and professional identity and career future might be affected by globalization. Thus, this mixed design study aimed at examining Northeastern Italian adolescents’ thinking about globalization and at exploring the potential role of education (the type of school) in conceptualizing globalization. Methods: A total of 163 Italian adolescents (42.3% boys and 57.5% girls) aged 16–19 years, attending a scientific lyceum or a commercial, technological, or professional high school participated in the study. Participants were invited to explain the concept of globalization. Their answers were analyzed using a thematic analysis procedure. Results: & Conclusions:. The analyses revealed adolescents’ limited and inaccurate understandings of globalization, with almost exclusive emphasis on the positive aspects of globalization, and without a critical understanding of its consequences. Moreover, no differences related to their educational experience (the type of school they attended) or socio-economic status emerged when reporting their understanding of globalization. The results suggested the relevance of a training process for the promotion of critical thinking, especially in the field of career guidance
Therapeutic options in lung neuroendocrine tumors: between established concepts and new hopes
No full textTypical (TC) and atypical (AC) carcinoids are low-grade neuroendocrine tumors (NETs) of the lung and, are neglected diseases in respect of both high-grade NETs of the lung (i.e. small-cell lung cancer and large-cell neuroendocrine carcinoma) and gastroenteropancreatic (GEP)-NETs. AC and TC account for 2 and 0.2% of all thoracic malignancies, respectively, and have a 12.9% chance of metastatic spread at diagnosis, reaching up to 20% during disease history. There are very few trials specifically designed for lung NETs, and therapeutic options are mainly derived by studies carried out in patients with GEP-NETs. We report a case of a patient affected by AC progressed to available standard treatments who received off-label treatment with sunitinib, a well-known multitarget tyrosine-kinase inhibitor with marked antiangiogenic activity, used routinely for the treatment of GEP-NETs. During treatment, the patient required the administration of an alternative schedule to improve tolerability, with benefit, and achieved a partial response according to the RECIST criteria, which is unusual in NETs. We critically reviewed available data supporting the use of somatostatin analogs, chemotherapy, and target therapies (everolimus and sunitinib) in advanced lung NETs. In the review, ongoing trials in lung NETs and future developments in this research field are also discussed
