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
A chatbot-based coaching intervention for adolescents to promote life skills: pilot study
Full text linkBACKGROUND: Adolescence is a challenging period, where youth face rapid changes as well as increasing socioemotional demands and threats, such as bullying and cyberbullying. Adolescent mental health and well-being can be best supported by providing effective coaching on life skills, such as coping strategies and protective factors. Interventions that take advantage of online coaching by means of chatbots, deployed on Web or mobile technology, may be a novel and more appealing way to support positive mental health for adolescents.OBJECTIVE: In this pilot study, we co-designed and conducted a formative evaluation of an online, life skills coaching, chatbot intervention, inspired by the positive technology approach, to promote mental well-being in adolescence.METHODS: We co-designed the first life skills coaching session of the CRI (for girls) and CRIS (for boys) chatbot with 20 secondary school students in a participatory design workshop. We then conducted a formative evaluation of the entire intervention-eight sessions-with a convenience sample of 21 adolescents of both genders (mean age 14.52 years). Participants engaged with the chatbot sessions over 4 weeks and filled in an anonymous user experience questionnaire at the end of each session; responses were based on a 5-point Likert scale.RESULTS: A majority of the adolescents found the intervention useful (16/21, 76%), easy to use (19/21, 90%), and innovative (17/21, 81%). Most of the participants (15/21, 71%) liked, in particular, the video cartoons provided by the chatbot in the coaching sessions. They also thought that a session should last only 5-10 minutes (14/21, 66%) and said they would recommend the intervention to a friend (20/21, 95%).CONCLUSIONS: We have presented a novel and scalable self-help intervention to deliver life skills coaching to adolescents online that is appealing to this population. This intervention can support the promotion of coping skills and mental well-being among youth
Attività fisica e comportamento sedentario
No full textRegular exercise significantly affects the quality of life, improving both the physical and psychological state of health and reducing the risk of general mortality. Regular exercise produces numerous physiological benefits, with the subsequent reduction in the risk of insurgence of serious pathologies, such as cardiovascular diseases, diabetes, obesity, some types of tumours and osteoarticular diseases. The literature advises children and adolescents to do from 30 to 60 minutes of moderate physical exercise for a few days a week and recommends avoiding long periods of inactivity. Results At the regional level: • the percentages of those who carry out exercise for at least one hour, 5 or more days a week, are similar, being 31% for the stratum of 11-year olds, 33% for that of 13-year olds, and about 27% for the stratum of 15-year olds; • in general, the analysis of data has found that 15-year olds are less active, and gender comparison has shown that the most inactive are girls in all three strata. Nonetheless, among girls, those who report doing physical exercise most regularly are the 13-year-olds (39%); • during school days 12% of 11-year olds, 20.3% of 13-year olds and 19% of 15- year olds watch television for more than 4 hours a day. The numbers increase if weekends are taken into account; in relation to the gender difference, only in the 11-year old stratum does the phenomenon have a strictly male tendency - in the other two strata there are no significantly statistical differences; • the largest percentage of 15-year olds report doing homework during the week (35.4%), followed by 13-year olds (32.5%) and 11-year olds (30.7%); those who spend 3 or more hours doing this type of sedentary activity are notably girls, and the rather large gap between boys and girls tends to increase with age; at weekends, the estimates decrease in all three strata of the sample. Comments Data comparing exercise carried out in the last 7 days and during a normal week show little variation, and this indicates reliable answers to the questionnaires. In relation to sedentary activity in front of the TV, at weekends the rate increases more in the first two strata. Maybe 15-year olds have other things to do such as going to the discoteque on Sunday afternoon, or other forms of enjoyment which do not involve huge amounts of time in front of the TV screen. Girls are more interested in homework than boys, in particular 13-year old and 15-year olds
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
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
