Patients' understandings of heart attack: implications for prevention of recurrence
No full textPatients' willingness to undertake secondary preventive strategies following heart attack are likely to be affected by their understandings of their condition. This qualitative study explored patients' understandings of heart attack in order to contribute to the design of effective secondary prevention services. In-depth interviews were conducted with 25 patients with myocardial infarction (MI). These data indicate that information received from health professionals encourages patients to view heart attack as an acute event rather than a symptom of a chronic condition and that this understanding provides patients with low motivation for long-term lifestyle change. Patients may benefit from understanding a heart attack as an acute symptom of an underlying disease process which long-term medication and behavioural change can help to check. In order to achieve this, health professionals need to examine patients' understandings of their heart attack and recovery and to provide information about lifestyle which engages with these understandings
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
Patients' and practice nurses' perceptions of secondary preventive care for established ischaemic heart disease: a qualitative study
No full textA significant proportion of patients with established ischaemic heart disease remain unrecognized in general practice and those who are receiving treatment are experiencing sub-optimal care.The provision of coronary prevention by practice nurses may be an important strategy to improve the quality of this care, and this is feasible and effective.This study explored what occurred during patients' initial assessment for secondary prevention of ischaemic heart disease with a practice nurse and investigated patients' and practice nurses' views of nurse-led clinics in primary care.Nurses were effective in history taking and offering reassurance and dietary advice, yet were less confident in discussing patients' understandings of heart disease and related medication.Practice nurse-led coronary preventive care is acceptable to both nurses and patients.Further practice nurse education is required in heart disease, cardiac medications and skills necessary for exploring and challenging patients' understandings of these issues
Improving palliative care services : a pragmatic model for evaluating services and assessing unmet need.
No full textEvaluating local palliative care services and identifying gaps in services for patients are crucial to the development of services which enable people to die at home in a well-supported environment. A review of the local strategy for providing respite and support services for palliative care patients and their carers was carried out in one area of south-east England. The review comprised four elements: identification of services available; interviews with provider ‘stakeholders’; interviews with patients and carers; questionnaire survey of general practitioners and district nurses. The findings and outcome are described. It is suggested that this approach could be adopted by health authorities to form one part of a comprehensive system of needs assessment. Alternatively, it could be used by groups of providers to evaluate existing services and to identify potential improvements to services. Advantages and disadvantages of the approach for both commissioners of such reviews and those carrying them out 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
