Satisfaction with the NHS has dropped 12% since 2010 and the government’s rhetoric is largely to blame
No full textMark Hellowell argues that the government’s own rhetoric during late 2010 and 2011 may be responsible, at least partly, for the precipitous decline in satisfaction with the NHS
The move from PFI to PF2 is likely to make it more, rather than less, expensive to deliver new healthcare facilities in the future
No full textWhat impact the introduction of ‘Private Finance 2’ (PF2) have on the cost of projects for the public authorities that use it? Mark Hellowell is the author of a new report which looks into how PF2 will affect the healthcare sector. He writes that, far from avoiding the ‘PFI mess’ ascribed to its predecessors, the government is taking a route that may lead to another
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
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
Private financing for public infrastructure is here to stay despite “PFIs” being consigned to history
No full textGeorge Osborne has recently outlined new thinking on private financing for major public service projects. Widely criticised as saddling public bodies with long-term debts, the Private Finance Initiative funding model has been used extensively since the 1990s. Mark Hellowell examines whether the Chancellor’s speech outlines a strategic shift or is more semantic
Meeting the demand for care will mean ensuring the private sector health market is fit for competition
No full textAs the National Health Service struggles to meet the country’s hospital care needs, the future may lie in the hands of the private sector. However, Mark Hellowell argues that serious market reforms are to be made to guarantee private acute care is fit for the task
