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
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
Leverantörsbytens verkliga kostnad: Mer än bara enhetskostnaden
No full textThe purchasing department's impact on the companies and its results has grown as more goods and services are purchased from other companies. One of the department's most important tasks is to keep costs down, and therefore are alternative suppliers constantly sought, often in other countries with lower wages. Previous research in the area focuses on relationships between buyers and sellers, how suppliers should be selected, and what supply chains should look like. The research around the termination of supplier relationships, changes to new suppliers, and the effect it has on the operations is limited and therefore interesting to investigate. It is common for companies to switch suppliers solely with the unit price in focus and that this leads to large effects outside the purchasing department that are difficult to predict and quantify and that in some cases leads to reshoring. The purpose of this study was to investigate and analyze which costs arise when switching suppliers and to show how the information about these can be used to make better purchasing decisions in the future. Three research questions were formulated to achieve the purpose: what costs arise, what impact does a change of supplier lead to and how can the decision be supported when changing supplier. A case study was done at a manufacturing company in northern Sweden. Semi-structured interviews and observations were carried out within relevant departments and the collected empirical evidence was then compared with previous research in the subject. The case study consisted of both qualitative and quantitative research methods and the approach was abductive. The result shows that supplier changes lead to direct costs for the purchasing department in the form of salaries, travel and system training, and indirect costs in the form of material planning, transport, and extra handling. Furthermore, the risks of major impact on the business are demonstrated if the supplier evaluation is done in an inadequate manner and with too much focus on the unit price. The resulting information can be used to make better decisions in the future by improving supplier evaluation methods, ensuring that review is conducted on all supplier changes, and involving more internal and external departments to get a better overall picture before a decision on a supplier change is made. In the study, a model supporting decision on supplier change has also been developed, which leads to both practical and theoretical contributions.Inköpsavdelningens påverkan på företagen och dess resultat har växt i takt med att allt fler varor och tjänster köps in från andra företag. En av avdelningens viktigaste uppgifter är att hålla nere kostnaderna och därför söks ständigt alternativa leverantörer, ofta i andra länder med lägre lönekostnader. Tidigare forskning inom området fokuserar främst på relationer mellan köpare och säljare, hur leverantörer bör väljas och hur försörjningskedjor ska se ut. Forskningen kring upphörandet av leverantörsrelationer, byten till nya leverantörer och vilken effekt det får på verksamheterna är begränsad och därför intressant att undersöka. Det är vanligt att företag byter leverantör enbart med enhetspriset i fokus och att detta leder till stora påföljder utanför inköpsavdelningen som är svåra att förutspå och kvantifiera och som i vissa fall leder till reshoring. Syftet med denna studie var att undersöka och analysera vilka kostnader som uppstår vid byte av leverantör samt att visa hur informationen om dessa kan användas för att ta bättre inköpsbeslut framöver. Tre forskningsfrågor formulerades för att uppnå syftet: vilka kostnader uppstår, vilken påverkan leder ett leverantörsbyte till och hur kan beslutet stödjas vid byte av leverantör. En fallstudie gjordes på ett tillverkande företag i norra Sverige. Semistrukturerade intervjuer och observationer utfördes inom relevanta avdelningar och den insamlade empirin jämfördes sedan med tidigare forskning inom ämnet. Fallstudien bestod av såväl kvalitativa som kvantitativa forskningsmetoder och angreppssättet var abduktivt. Resultatet av studien visar att leverantörsbyten leder till direkta kostnader för inköpsavdelningen i form av löner, resor och utbildning i system och indirekta kostnader i form av materialplanering, transporter och extrahantering. Vidare påvisas riskerna för en stor påverkan på verksamheten om leverantörsutvärderingen görs på ett bristfälligt sätt och med för mycket fokus på enhetspriset. Den framkomna informationen kan användas för att ta bättre beslut i framtiden genom att förbättra metoderna för leverantörsutvärdering, säkerställa att granskning utförs vid alla leverantörsbyten samt genom att involvera fler interna och externa avdelningar för att få en bättre helhetsbild innan ett beslut om leverantörsbyte tas. I studien har även en modell som kan användas som beslutsstöd vid leverantörsbyten tagits fram, vilket lett till såväl praktiska som teoretiska bidrag
