Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Health Action Zones: the ‘third way’ of a new area-based policy?
No full textHealth Actions Zones (HAZs) have been identified as initiatives reflecting the "third way" policies espoused by the UK New Labour Government. Like other area-based or zone initiatives, HAZ programmes are designed to tackle inequalities and exclusion in some of the most deprived areas of the UK. This is to be achieved through partnerships between the public, private and voluntary sectors, and most significantly, communities themselves. Health Action Zones embrace communities and attempt to foster involvement in health improvement, often using established community development models. The present paper uses the findings of an ongoing process study into the development of one zone in the north-east of England to consider community involvement in practice. The benefits and challenges of involving communities in the HAZ process are presented, and the relevance of this for future programmes and policy are discussed
From retreat to health centre: legislation, commercial opportunity and the repositioning of a Victorian private psychiatric hospital
No full textThis paper examines the interplay of commercial imperatives and health care legislation in the survival of a privately owned psychiatric hospital in Guelph, Ontario, Canada. Using documentary and archival evidence, we show how the Homewood Retreat (later Sanitarium, and eventually Health Centre) was able to respond to and anticipate legislative developments through the agency of successive medical superintendents and the structural positioning of the institution as an inextricably integrated element in local and provincial mental health provision. Our case study is used to draw out wider lessons concerning agency, legislative context and treatment modality in the determination of organizational histories. We conclude by noting the important role of the private sector in ensuring the continued provision of an asylum form of mental health care
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
Predicting small area health-related behaviour: a comparison of multilevel synthetic estimation and local survey data
No full textA recent paper in Social Science and Medicine (Twigg et al. 50 (2000) 1109) outlined an approach to the estimation of prevalences of small-area health-related behaviour using multilevel models. This paper compares results from the application of the multilevel approach with those derived using the more traditional strategy of the local 'lifestyle' survey. Estimations of smoking prevalence and high alcohol consumption are examined and critical assessments made of both estimation approaches. It is concluded that the alternative method is more suited towards the prediction of smoking rates as opposed to unsafe alcohol consumption
