Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
Improved Planning Capability for Increased Delivery Precision and Reduced Capital Tie-Up – A Case Study in the Automotive Industry
Tillverkande företag står idag inför komplexa utmaningar till följd av globalisering, digitalisering och ökade hållbarhetskrav, vilket gör effektiva produktions- och logistikprocesser avgörande. Två centrala prestationsfaktorer är leveransprecision och kapitalbindning. En intern undersökning hos det studerade företaget identifierade betydande förbättringspotential inom produktionsplaneringen. Historiska data visade en försämring av både leveransprecision och kapitalbindning, huvudsakligen till följd av brister i planeringsförmågan. Syftet med denna studie var att stärka Företagets interna planeringsprocess samt att identifiera och hantera externa faktorer som påverkar leveransprecision och kapitalbindning. Studien har genomförts med stöd av Double Diamond-metodiken, vilken omfattar faserna Discover, Define, Develop och Deliver. Metoder som tillämpades inkluderar litteraturstudier, dokumentanalyser, intervjuer och observationer för att kartlägga nuläget. Rotorsaksanalys med hjälp av Ishikawa-diagram användes för att definiera och prioritera identifierade problem. Studien fokuserade särskilt på produktionsflöde X samt kapitalbindningen i lagerförda fordon före produktion, vilket utgjorde 34,1 procent av den totala kapitalbindningen. Centrala problem som identifierades inkluderade planering för 100 procent kapacitet trots lägre faktisk kapacitet, ineffektiv arbetsfördelning på grund av bristfällig informationshantering, produktionsstopp vid personalfrånvaro, inkonsekventa leveranser från Koncernbolaget samt otillförlitliga data från ett besvärligt stämplingssystem. Analysen visade att planeringsprocessens mognadsgrad begränsas av bristen på dokumenterade rutiner och standardiserade arbetssätt, vilket gör den personberoende. Selekterade förbättringsförslag, att planera för 93 procent kapacitet, använda en datadriven produktionsplaneringsmodell, införa en montör utanför kapacitet, genomföra kontinuerlig analys av leveransdata från Koncernbolaget samt kombinera kulturella och tekniska förbättringar av stämplingssystemet, togs fram och dess effekt bedömdes i samverkan med nyckelpersoner inom Företaget. Förbättringsförslagen bedöms kunna öka Företagets leveransprecision med 58 procent och minska kapitalbindningen med 10 procent.Manufacturing companies today face complex challenges driven by globalization, digitalization, and sustainability demands, making efficient production and logistics processes essential for competitiveness. Two key performance factors are delivery precision and capital tie-up. An internal investigation at the case company revealed significant potential for improvement in production planning, with historical data showing a decline in both delivery precision and capital efficiency, largely due to deficiencies in planning capabilities. This thesis aimed to enhance the company's internal planning processes and address external influences affecting delivery precision and capital tie-up. The Double Diamond methodology guided the research through the phases of Discover, Define, Develop, and Deliver. Methods included literature review, document analysis, interviews, and observations to assess the current state. Root cause analysis, via Ishikawa diagram, were used to define and prioritize key issues. The study focused on the production flow X and pre-production inventory, which accounted for 34.1 percent of total capital binding. Key issues identified included planning based on 100 percent theoretical capacity despite lower actual performance, inefficient work distribution due to poor information flow, production disruptions during staff absences, inconsistent supply from an affiliated company, and unreliable data from a problematic time registration system. The planning process was found to lack standardized routines, making it overly dependent on individual experience. Improvement proposals, such as planning based on 93 percent capacity, implementing a data-driven production planning model, assigning an assembler outside of capacity, continuously analyzing the parent company´s delivery performance, and implementing both cultural and technical changes to the time registration system, were collaboratively selected and evaluated. These changes are estimated to improve the company´s delivery precision by 58 percent and reduce capital tie-up by 10 percent
