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
Onderwijs en arbeidsmarkt in MKBA's
No full textCPB en PBL werken aan een leidraad voor maatschappelijke kosten-batenanalyse (MKBA) voor alle terreinen van overheidsbeleid. Sinds het jaar 2000 is een groot aantal MKBA’s uitgevoerd van transportbeleid, in het bijzonder infrastructuurprojecten. Op andere gebieden worden meer incidenteel MKBA’s uitgevoerd, waardoor de ervaring met MKBA’s op deze terreinen nog beperkt is. Binnen de wetenschappelijke begeleidingscommissie van de algemene MKBA leidraad zijn vragen gerezen over de toepasbaarheid van de leidraad op het sociale domein, in het bijzonder de terreinen onderwijs en arbeidsmarkt. Deze vragen betreffen onder meer de kwaliteit van effectschattingen die aan MKBA’s ten grondslag liggen en de wijze waarop effectschattingen kunnen worden ‘vertaald’ in kosten en baten. Naar aanleiding van deze vragen benadrukken CPB en PBL het belang van effectschattingen in de leidraad en geven zij een enkel voorbeeld. Dit blijkt echter niet voldoende om de zorgen weg te nemen. Dit was aanleiding voor een nadere verkenning van de toepasbaarheid van MKBA’s op het sociale domein. Deze actie is gericht op MKBA’s van hoge kwaliteit en op draagvlak. De verkenning is uitgevoerd via gesprekken van voorzitter Carl Koopmans met de meest bij deze onderwerpen betrokken leden van de commissie: Pierre Koning (arbeidsmarktdeskundige) en Dinand Webbink (onderwijsexpert). In deze gesprekken is gezamenlijk gezocht naar mogelijkheden om de kwaliteit van toepassing van de leidraad op het sociaal domein te borgen. Op basis van de gesprekken is deze notitie geschreven. De notitie is tot stand gekomen tijdens de laatste fase van het opstellen van de MKBA leidraad. Als volgende stap schrijft de wetenschappelijke begeleidingscommissie een second opinion. Voorzien is dat in een volgend stadium zogenaamde ‘werkwijzers’ worden opgesteld voor respectievelijk arbeidsmarkt en onderwijs waarin de MKBA leidraad verder wordt uitgewerkt op deze terreinen. De auteurs van de leidraad kunnen delen van deze notitie overnemen in de leidraad. Mogelijk zullen onderdelen van deze notitie deel uitmaken van de second opinion. En ten slotte vormt de notitie een voorzet voor de werkwijzers. De notitie gaat afzonderlijk in op belangrijke aspecten. Vervolgens worden aanbevelingen geformuleerd
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
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
The Relationship Between Sport and Social-Emotional Skills
No full textThis study will look at the effect of sport on three categories of tasks that require socialemotional
skills: (1) Achieving goals, (2) Working with others and (3) Manage emotions. The
research question is twofold. First of all, what is the effect of participating in sport on socialemotional
skills? Second, the sports will be divided in team sports and individual sports and the
question will be investigated if participating in a team sport has a larger positive effect on life
skills.
These questions are investigated by using two empirical strategies: an OLS model with
control variables and a fixed effects model. Data of the TRAILS study is used to investigate the
questions. The TRAILS study is a prospective cohort study, started in 2001. Since then a group
of young people from the Northern part of the Netherlands is closely monitored. Every two
years, over 2,500 youngsters are subjected to questionnaires, interviews, and other tests.
Based on the unique TRAILS data I concluded first of all, that participation in sport has a
significant positive effect on the social-emotional skills associated with ‘working with others’.
After making a distinction between individual sports and team sports, the estimates showed that
participating in a team sport has a significant positive effect on the life skills associated with
‘managing emotions’, ‘achieving goals’, and ‘working with others’. The conclusions are checked
by two different kinds of robustness tests. The robustness tests underscore the positive effect of
team sport, however they also indicate that there could exist a reverse causality problem. More
research will be needed to address this problem in order to achieve clearer and more robust conclusions
