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
Adding value to outpatient heart failure services and the patient journey through digital transformation of services
Get PDFIntroduction
Heart failure (HF) is a chronic condition affecting over 900,000 people in the UK. The management of patients with HF frequently involves regular face-to-face appointments. Digital transformation of care with telemedicine, remote monitoring and mobile applications (Apps) may help improve patient experience and relieve demand on services. The Covid-19 pandemic resulted in an acceleration in telemedicine.
This thesis evaluates pre-pandemic HF services at the Royal Brompton Hospital (RBH), identifying potential areas for improving patient journeys.
Methods
Retrospective cohort studies including over 200 patients were used to analyse the activities and actions resulting from HF clinic appointments over 3 years.
Time-and-motion studies were conducted for each of the 4 consultant-led HF clinics at RBH, where flow through hospital was analysed for 58 patients.
Eight clinicians and 8 patients who had undergone telemedicine consultations were interviewed about their experiences and perceptions, with narrative data thematically analysed.
Focus groups and existing educational material were used to design an educational App for HF.
Results
Most HF patients under long-term follow-up were followed up twice yearly. At clinic visit, worsening HF symptoms and therapy change by clinicians were uncommon (21% and 36% of appointments respectively).
Patients spent a median of 103 minutes in hospital on the day of an appointment for a median 20-minute consultation. The majority of consultations ran late.
Clinicians and patients found telemedicine consultations generally acceptable, but both groups identified changes in time utilisation, clinical assessment, communication, and technology. Telemedicine appointments were shorter and involved less time waiting and travelling for patients. Patients and clinicians agreed that when patients are “stable”, telemedicine is preferred.
A prototype HF educational “Avatar”-based App was produced.
Conclusion
Digital transformation of outpatient services, including telemedicine can improve patient and clinician experience, efficiency and rationalise limited resources, thus adding value to outpatient HF care.Open Acces
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
Treatment decision-making in heart failure management
Get PDFBackground:
Demands for increased patient and public involvement in healthcare has led to changes in policy on decision-making. The shared decision-making (SDM) model is advocated in current health policy and encourages partnership between patients and professionals. Yet limited evidence exists of its effects on clinical outcomes and cost. As a result, a policy-practice divide has emerged. Heart failure management has adopted a more personalised approach to treatment. Yet knowing the treatment that is likely to have the best therapeutic effect does not mean it is right for that individual patient. Patients’ health decisions are influenced by a variety of factors, including their experience of illness and disease beliefs. Professionals need increased understanding of how patients make decisions to support the integration of SDM in to practice.
Purpose:
This thesis aims to explore different stakeholder perspectives of decision-making in heart failure management and to identify the barriers and facilitators to SDM.
Method:
A mixed-methods study design involving: Pan-London analyses of multidisciplinary team (MDT) meetings; a qualitative interview study analysed by thematic analysis (Glaser and Strauss, 1967); a Delphi consensus survey. Together these data inform key recommendations to improve communication about treatments and the design of future research.
Results:
The structures, functions and processes of MDT meetings varied within and across NHS Trusts. Professionals’ assumptions about patient preferences, information needs and approach to decision-making were key barriers to a SDM approach. There was agreement that patients should be involved in treatment decisions, yet there was limited consensus on the priority areas for improvements to practice.
Conclusion:
Considerable variation exists in the process of treatment decision-making and there is limited concordance between the views of patients, their families and health professionals. Professionals need to tailor their approach to treatment discussions and assess patients health information-sourcing behaviour to better support patient involvement in decision-making.Open Acces
