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
Tendances et déterminants de l’utilisation de l’aide à domicile subventionnée par le gouvernement par les personnes âgées au Canada, 1996-1997 à 2009-2010
Get PDFIl est connu que le vieillissement de la population canadienne va augmenter la demande d’aide à domicile et qu’un soutien insuffisant du secteur public accroît l’implication des réseaux informels et privés. En s’appuyant sur les données de l’Enquête nationale sur la santé de la population (ENSP) et de l’Enquête sur la santé dans les collectivités canadiennes (ESCC), cette recherche analyse les tendances et déterminants de l’utilisation de l’aide à domicile subventionnée par le gouvernement au Canada et en Ontario entre 1996-1997 et 2009-2010.
Il en ressort que la proportion de bénéficiaires âgés de 65 ans et plus est en diminution, passant de 9,9% à 9,2% au Canada (1996-1997 à 2005) et de 10,2% à 8,8% puis 9,6% en Ontario (1996-1997, 2005, 2009-2010). Les compressions sont particulièrement ressenties dans les services de maintien à domicile, dont l’aide pour les travaux ménagers (de 51% à 34% en Ontario). Les personnes âgées, les femmes, les gens vivant seuls ou qui ont besoin d’assistance pour accomplir certaines activités de la vie quotidienne (AVQ) ou activités instrumentales de la vie quotidienne (AIVQ) reçoivent de moins en moins d’aide publique à domicile.
En conclusion, le présent système de santé, qui semble se concentrer sur les soins de santé plutôt que sur les services de maintien, ne répond pas aux besoins des personnes âgées. Par ailleurs, le cas ontarien évoque l’impact que peuvent avoir les décisions politiques sur l’utilisation de l’aide à domicile. Les résultats suggèrent qu’entre 1996-1997 et 2005, ce sont surtout les personnes âgées de 18 à 64 ans et ceux nécessitant des soins qui bénéficièrent des programmes publics. Durant la période suivante (2005 à 2009-2010), il semble y avoir un intérêt plus marqué pour les 65 ans et plus dont la proportion d’utilisateurs s’accroît plus rapidement.It is known that the aging of the Canadian population will increase the demand for home care and that insufficient support from the public sector increases the implication of the informal and private networks. Using cross-sectional data from the National Population Health Survey (NPHS) and the Canadian Community Health Survey (CCHS), this research analyzes the trends and predictors of subsidized home care in Canada and Ontario between 1996/97 and 2009/10.
It shows that the proportion of care receivers aged 65 and older is decreasing, going down from 9.9% to 9.2% in Canada (1996/97 to 2005) and from 10.2% to 8.8% then 9.6% in Ontario (1996/97, 2005, 2009/10). Government cuts are particularly felt in terms of home support services, like support for housework (from 51% to 34% in Ontario). Older persons, women, people living alone or those who need assistance to perform some activities of daily living (ADLs) or instrumental activities of daily living (IADLs) are receiving less and less subsidized home care.
In conclusion, the actual health system, that appear to focus on health care instead of home support services, do not meet the needs of older persons. Furthermore, the Ontario case evokes the effect that policies can have on home care utilization. Results suggest that between 1996/97 and 2005, it is mostly persons aged from 18 to 64 years old or needing health care that benefited from the public program. During the next period (2005 to 2009/10), there seems to be a greater interest for the 65 and older, whose proportion of users increases more rapidly
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
Tendances de l’incapacité chez les aînés vivant dans les ménages privés au Canada, et caractéristiques sociodémographiques associées, 1994-2005
Get PDFLe vieillissement de la population canadienne qui est appréhendé dans les années à venir
entrainera son lot de défis pour l’administration des soins et services de longue durée.
Par contre, une amélioration de l’état de santé fonctionnelle de la population pourrait
atténuer le rythme de croissance du nombre d’aînés en état d’incapacité. Utilisant les
données transversales de l’Enquête nationale sur la santé de la population (ENSP) et de
l’Enquête de santé dans les collectivités canadiennes (ESCC), cette recherche analyse les
tendances dans les niveaux d’incapacité chez les personnes de 65 ans et plus vivant dans
les ménages privés au Canada entre 1994 et 2005, ainsi que les caractéristiques
sociodémographiques associées au risque d’être en incapacité. Les résultats montrent
que la prévalence de l’incapacité est à la baisse durant la période, et que parmi les
personnes en incapacité, la proportion présentant une incapacité légère a diminué. Tout
étant égal par ailleurs, certaines caractéristiques sociodémographiques augmentent le
risque pour une personne âgée d’être en incapacité, notamment l’âge, être une femme, la
faible scolarité, et être veuf, séparé ou divorcé. Cependant, les limites relativement
importantes quant à la qualité des données font en sorte que nous devons interpréter ces
résultats avec prudence.The ongoing aging of the Canadian population that will accentuate in the coming years
will cause a lot of challenges for health care administration and long-term services.
However, improved functional health status of the population could reduce the rate of
growth in the number of disabled elderly. Using cross-sectional data from the National
Population Health Survey (NPHS) and the Health Survey (CCHS), this study analyzes
trends in disability levels among people aged 65 years old and over living in private
households in Canada between 1994 and 2005, and the sociodemographic characteristics
associated with the risk of being disabled. The results show that the prevalence of
disability has been declining during the period, and that among people with disability,
the proportion with mild disabilities has decreased. Other things being equal, several
sociodemographic characteristics increase the risk for an elderly to declare be disabled.
These include age, being a woman, low education, and being widowed, separated or
divorced. However, important limitations on data quality lead us to interpret these
results with caution
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
