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
Recognising the influence of inter-professional relations on end of life care transitions: views of bereaved carers and professionals
No full textIntroduction: the end-of-life care needs of older adults with multiple conditions are complex and involve a range of professionals working in different settings. This study focuses on transitions, as vulnerable points in care pathways experienced by a high proportion of the older population at the end of life.Aims and methods: to understand how inter-professional relations influence transitions between settings for older adults at the end of life.Methods: in-depth qualitative interviews with 118 caregivers of decedents aged 66–98?years, who had died with heart failure, chronic obstructive pulmonary disease, stroke, selected cancers; 43 providers and commissioners of services in primary care, hospital, hospice, social care and ambulance services in England.Results: carers regretted that communication and handovers between professionals did not always take place where they felt them to be necessary, and perceived frequent, repeated assessments and interventions to be the consequence. Families felt compelled to take responsibility themselves and fill gaps left by deficiencies in inter-professional communication and working. Professionals described stereotypical divisions between health and social care, with differences in culture, language and approaches to patients or clients. The dominance of the medical model in end of life care was perceived to be unhelpful in creating close working relationships between health and social care. The impact of inter-professional tensions on patients and families went unacknowledged by staff.Conclusions: inter-professional relationships are an important influence on patient and family experiences of end of life care. It may be an overlooked source of inequit
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

No full textA study of socioeconomic disadvantage and end-of-life hospital admissions for older people with heart failure and lung cancer in England
No full textINTRODUCTION: At the end of life, a move into or out of hospital is one of the most disruptive events for older adults and their carers, with consequences for their mental, physical and emotional wellbeing. Evidence from elsewhere suggests that transitions are frequent and make little contribution to patients' wellbeing. Little is known about socioeconomic differences in end of life hospital admissions in England.AIMS AND METHODS: To investigate patterns of end-of-life hospital admissions by socioeconomic disadvantage. Analysis of linked hospital episode statistics and mortality data for England.RESULTS: Between 2001 and 2010, 300,304 people aged over 75 were admitted to hospital in England at least once in their last year of life with a diagnosis of lung cancer or heart failure. Eighty five percent of people admitted with lung cancer and 72% of heart failure cases underwent a transition into hospital in the last 3 months of life. In multivariate analysis, lower socioeconomic status (given by the index of multiple deprivation) being male and younger age were associated with frequent hospital admissions amongst people with heart failure (above the 90th centile). For lung cancer cases, younger age and male sex were associated with numbers of admissions above the 90th centile. People with lung cancer in the most disadvantaged IMD quintile were less likely to be admitted frequently, adjusting for age and sex. Residence in a care home was not associated with frequent admissions to hospital.CONCLUSIONS: Hospital admissions at the end of life are frequent, and vary with social disadvantage. Equitable end-of-life care in the community should be a future priority
