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

Increasing Socioeconomic Inequalities in Male Cirrhosis of the Liver Mortality: Australia 1981 - 2002
No full textLiver cirrhosis mortality is an indicator of harms associated with high levels of alcohol consumption. There is good evidence that changes in political and economic systems can lead to changing patterns of liver cirrhosis mortality. Socioeconomic inequalities in liver cirrhosis mortality have been periodically reported but there are few studies of changes in socioeconomic inequalities in liver cirrhosis mortality over time. This paper examines changes in socioeconomic inequalities in liver cirrhosis mortality in Australia for the period 1981 - 2002. Age standardised, liver cirrhosis mortality rates were calculated for occupational groupings for Australia 1981 - 2002. Occupations were grouped into non-manual and manual categories, and there was imputation for missing data. Despite decreasing overall liver cirrhosis mortality rates over time, liver cirrhosis mortality continues to account for about 3% of all deaths. Manual workers have consistently experienced liver cirrhosis mortality rates which are twice or more the rate experienced by non-manual workers. These inequalities appear to have increased in recent years and currently appear to be at historic highs (manual workers have mortality rates of about 2.5 times those of non-manual workers). Increasing socioeconomic inequalities in liver cirrhosis mortality in Australia suggest that lower SES groups have, over time, increased their level of harmful alcohol consumption relative to middle and higher SES groups. It is suggested that this might be attributed to a relative improvement in the affordability of alcohol over time. [Najman JM, Williams GM, Room R.

The Development and Validation of the Indigenous Risk Impact Screen (IRIS): a 13-item Screening Instrument for Alcohol and Drug and Mental Health Risk
No full textThe study aimed to assess the psychometric properties of the Indigenous Risk Impact Screen ( IRIS) as a screening instrument for determining ( i) the presence of alcohol and drug and mental health risk in Indigenous adult Australians and ( ii) the cut- off scores that discriminate most effectively between the presence and absence of risk. A cross- sectional survey was used in clinical and nonclinical Indigenous and non-Indigenous services across Queensland Australia. A total of 175 Aboriginal and Torres Strait Islander people from urban, rural, regional and remote locations in Queensland took part in the study. Measures included the Indigenous Risk Impact Screen ( IRIS), the Severity of Dependence Scale (SDS), the Alcohol Use Disorders Identification Test ( AUDIT) and the Leeds Dependence Questionnaire (LDQ). Additional Mental Health measures included the Depression Anxiety and Stress Scale ( DASS- 21) and the Self- Report Questionnaire ( SRQ). Principle axis factoring analysis of the IRIS revealed two factors corresponding with ( i) alcohol and drug and ( ii) mental health. The IRIS alcohol and drug and mental health subscales demonstrated good convergent validity with other well- established screening instruments and both subscales showed high internal consistency. A receiver operating characteristics ( ROC) curve analysis was used to generate cut- offs for the two subscales and t- tests validated the utility of these cut- offs for determining risky levels of drinking. The study validated statistically the utility of the IRIS as a screen for alcohol and drug and mental health risk. The instrument is therefore recommended as a brief screening instrument for Aboriginal and Torres Strait Islander people
