Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Adherence to endocrine therapy in women with breast cancer: development and preliminary validation of the A-BET questionnaire
No full textPurpose. To develop an Italian tool that measures the therapy
adherence of women with breast cancer undergoing treatment with
oral endocrine therapy.
Methods A two-phase study was conducted, which followed the
guidelines of the European Statistical System for the development and
validation of a questionnaire. In the first phase, the questionnaire was
developed; in the second phase, a preliminary validation was carried
out on patients with breast cancer undergoing treatment with oral
hormonal therapies.
Results In its final version, the questionnaire presents 6 main items
which aim to investigate the level of adherence, the degree of awareness
of the nature of the drug taken and the reasons that may influence nonadherence. 82 patients were recruited in the validation study, with an
average age of 56.4 years, while for the re-test 40 were selected with an
average age of 57.3 years. Content validity reported excellent results.
Cronbach's alpha of each item showed a strong degree of correlation.
Conclusions. The creation of a tool for measuring adherence to
endocrine therapy in breast cancer patients can be a valuable support
for healthcare professionals involved in their care. Future studies should
be aimed at using A-BET (Adherence – Breast Endocrine Therapy) on
larger cohorts of patients in order to verify its validity / reliability more
accurately and to be able to generalize the results
Evaluation of the perception of clinical competencies by nursing students in the different clinical settings: An observational study
No full textIntroduction. The university educational sphere has many dilemmas. The question of sufficient knowledge and skills for students to acquire abilities to provide care in different clinical setting is one important dilemma. Aim. To measure the level of competencies by nursing students and its application in different clinical environments. Methods. Nursing students of two Italian universities participated in the research. Data collection took place April to July 2015 using the Nurse Competence Scale. The Strengthening Reporting of Observational Studies in Epidemiology Guidelines was used to describe the study. Pearson's chi-square test, Student's t test, and regression tests were used for statistical analysis. Results. The questionnaire response rate was 87.27% (n = 698). Most of the nursing students assessed their level of competency as 'good' and evaluated themselves as more competent than their actual nursing role. Students also appraised themselves as competent either via their clinical practices accomplished or in the therapeutic interventions. Conclusion. This study shows that the self-evaluation of the competencies acquired by nursing students in clinical settings in Latium and Abruzzo is of a good standard. This study also affirms that NCS is a valuable and reliable tool to measure clinical competencies in different clinical settings
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Role and skills of the oncology nurse. an observational study
No full textThe importance of nursing competence arises from its central role in influencing and determining care outcomes. The employment of adequately educated staff, able to base clinical decisions on the best scientific evidence, is one of the components required for delivering high quality nursing care in the oncological field. The aim of this study is to analyze - through the Nurse Competence Scale - the level of competence of nurses working in oncological settings
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
