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
Delirium prevention in hospices
Get PDFBackground
Delirium is common and distressing for hospice in-patients, with a prevalence of 58%-88% in the period before death. Systematic reviews have found that interventions targeting delirium’s modifiable risk factors significantly reduce its incidence (by approximately 40%- 50%) in hospitalised patients. Due to differences from other healthcare settings in risk factors and approaches to end- of- life care, interventions are needed which are tailored to the in-patient hospice context.
Aim
To develop evidence to inform the design of a behaviour change intervention for delirium care in hospice in-patient units.
Methods
My research was informed by the Medical Research Council framework for the development of complex interventions and behaviour change theory.
I conducted a systematic review of delirium risk factors. My qualitative synthesis, interviews and focused ethnography explored individual and contextual influences on hospice clinicians’ delirium prevention and management behaviours. Synthesis of these findings supported identification of target behaviours, mechanisms of action and behaviour change techniques for intervention design.
Results
My review of delirium risk factors found a positive association for opioid use with some evidence for dehydration, hypoxaemia, sleep disturbance and infection. However, the certainty of the evidence, from 28 included studies, was graded as low/ very low.
The current practice and research focus was on management, rather than prevention, of delirium. Many preventative behaviours were carried out as part of fundamental care, without the explicit intention of delirium prevention, but these behaviours reduced during illness progression.
My proposed intervention targets specific mechanisms of action (Knowledge, Emotion, Norms) to increase clinicians’ delirium prevention behaviours including routine assessment of risk factors, inclusion of delirium prevention in care decision-making and continuation of preventative behaviours during illness progression.
Conclusions
Evaluation of the feasibility and acceptability of this intervention is needed, before evaluating its effectiveness in reducing delirium, and related distress, for hospice patients
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Identifying barriers and facilitators for health risk behaviours among people with severe mental illness in Bangladesh and Pakistan:a qualitative study
Get PDFPeople with severe mental illness (SMI) are at greater risk of obesity, cardiovascular disease and diabetes than the general population, due to a higher prevalence of health risk behaviours. Research is needed to inform tailored interventions to improve the health behaviours (diet, physical activity and sleep) of people with SMI in South Asia as these behaviours are closely linked to obesity. The study aimed to explore the barriers and facilitators to healthy diet, physical activity and good sleep among individuals with SMI. A qualitative design was employed using photovoice, semi-structured interviews and focus group discussions. Participants included 16 people with SMI, 16 caregivers and 17 health professionals in Bangladesh and Pakistan. Data were analysed thematically, informed by the socio-ecological framework. A complex interplay of individual, familial and societal factors influenced these health behaviours. Individual factors include knowledge, beliefs and mental health limitations. Caregivers play a crucial role in influencing behaviour. At the societal level, gender expectations, financial constraints and religious influences significantly impact these behaviours. The insights from this research can inform tailored interventions for this vulnerable group and highlight the need for integrated services, financial support and improved urban planning
