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
Cohort Profile Update: The Young-HUNT Study, Norway
Get PDFThe Young-HUNT Study is the adolescent part of the Trøndelag Health Study (The HUNT Study), a population-based health study inviting all inhabitants, aged 13 years and above, of primarily the northern part of Trøndelag County (former Nord-Trøndelag) in the central part of Norway. The HUNT study has collected data in four subsequent surveys every 11th year over 1984–2017,1 but collections of adolescent data, aged 13–19 years, started for the first time in 1995.
The first three waves of The Young-HUNT Study were described in the original cohort profile.2 The first survey, Young-HUNT1 (YH1), was performed in 1995–97 (n = 8983, response rate 88%) as a part of the HUNT2 Survey. The Young-HUNT2 9YH2) survey was a 4-year follow-up of the youngest Young-HUNT1 participants (13–15 years). The Young-HUNT3 (YH3) survey was performed in 2006–08 as part of the HUNT3 Survey (n = 8200, 78.4%).
The Young-HUNT Study is a school-based survey primarily in the age range 13–19 years, and participant invitations are based on schools’ class lists of all registered school pupils, therefore also including a few 12- and 20-year-olds. As illustrated in Figure 1, The Young-HUNT allows longitudinal follow-up into adulthood, as well as linkage to a wide range of regional and national health registries by means of the unique identification number allocated to all Norwegian residents.1 All current residents ≥13 years of age in former Nord-Trøndelag have been invited to the surveys: HUNT2 (1995–97, 74 208 participants, 78.0%) and HUNT3 (2006–08, 58 999 participants, 70.1%).3publishedVersio
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
Mental health in Norwegian farmers: The HUNT Study
Get PDFAgriculture in industrialized countries has undergone major structural changes in recent decades. Farmers are exposed to a number of work-related stressors, such as high levels of work, unfavourable weather, financial difficulties, agricultural policies, and insecurities related to the future of their farms and of agriculture in general. These stressors may have an impact on the mental health of farmers, but the literature is inconclusive as to whether the mental health of farmers differs from that of people in other occupational groups. The Nord-Trøndelag Health Study (Helseundersøkelsen i Nord-Trøndelag, HUNT) is one of The world’s largest health studies to date. The HUNT Study is a total population-based study conducted in the county of Nord-Trøndelag, Norway, and consists of three cohorts: HUNT1 (1984-1986), HUNT2 (1995-1997), and HUNT3 (2006-2008). In total, more than 125,000 people have participated in the study, many of whom have had repeated measurements. We used data from all the three waves of the HUNT Study to investigate the mental health of Norwegian farmers.
Paper I reports a cross-sectional study of occupationally active HUNT3 participants in the age group 19 – 66 years. We found that the levels of farmers’ anxiety symtoms were similar to those in other occupational groups. Farmers, in particular male farmers, had a higher mean level of symptoms of depression compared with other occupational groups, including other manual occupations with presumed lower socio-economic status. We also found that the difference in the mean level of depression symptoms between farmers and the occupationally active general population increased with increasing age.
Paper II reports a prospective cohort study that included HUNT2 participants who were occupationally active and in the age group 19-62 years at baseline. We linked HUNT data with national registry data on disability and retirement pensions, and estimated the risk of receiving a disability pension for different occupational groups. We found that from a socioeconomic perspective farmers had an intermediate risk of being in receipt of a disability pension. We also investigated the association between symptoms of anxiety or depression in HUNT2 and the risk of receipt of a disability pension in the future. We found that symptoms of anxiety or depression at baseline were associated with a relatively similar absolute risk increase of receiving a disability pension in different occupational groups, with the possible exception of unskilled manual workers, who may have had a somewhat higher risk increase.
For the research reported in Paper III, we used data from all three waves of the HUNT Study, using several different designs. In a prospective cohort study, we found that the farmers had similar odds of having symptoms of psychological distress and anxiety 11 years after the baseline occupational measurement as other manual occupational groups. Farmers had the highest prospective odds of having symptoms of depression, although the differences between farmers and other manual occupations were minor. We also used national registry data to compare the mental health of farmers with that of their siblings working in other occupations.
We found that the farmers had higher odds of having symptoms of depression than their siblings in the periods 1995-1997 and 2006-2008. Regarding symptoms of anxiety, we did not find a difference between farmers and their siblings in the period 1995-1997, but there was a tendency for farmers to have higher odds of symptoms of anxiety than their siblings in the period 2006-2008. Further, we found that farmers appeared to follow the same general trends of symptoms of anxiety and depression as workers in other manual occupations, both over time and throughout their lifespan.
We found that farmers, in particular men, had a high prevalence of symptoms of depression compared with other occupational groups. With the possible exception of the sibling study, there did not appear to be any differences in symptoms of anxiety between farmers and other occupational groups. Farmers appeared to follow the same general trends in mental health as other occupational groups, but the results of the sibling analysis suggested that working in agriculture may have an impact on mental health. Additionally, our results suggest that there is a need for preventive mental health efforts within the agricultural industry and in the health care system, and may be of importance for shaping future agricultural policy
