Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Perspectives on the experience of being physically restrained: an integrative review of the qualitative literature.
Publications providing information on the safe use of physical restraints, guidelines for restraint use, and journal articles on the care of mental health patients are frequently devoid of information regarding patients\u27 perspectives on physical restraint. As physical restraint is a common procedure in many settings, the purpose of this review is to examine and summarize the qualitative literature on patients\u27 perspectives on being physically restrained, from 1966 through to 2009. A formal integrative review of existing qualitative literature on patients\u27 perspectives of physical restraint was conducted. Studies were critiqued, evaluated for their strength, and analysed for key themes and meanings. Twelve studies were ultimately identified and included in the review. Four themes emerged from the review, including negative psychological impact, retraumatization, perceptions of unethical practices, and the broken spirit. While little qualitative research on patients\u27 perceptions of physical restraint exists, findings within the current literature reveal serious implications for patients and nurses alike. Additional research into physical restraint implications for the patient-nurse dyad is needed, and nurses should approach the use of physical restraint with caution and awareness of their potential psychological impact
Variations on the Author
“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
Psychometric testing of the Agitation Severity Scale for acute presentation behavioral management patients in the emergency department.
Agitation is a vexing problem frequently observed in emergency department acute psychiatric patients, yet no instruments to measure agitation in this setting and population were found upon review of the literature. Previously developed agitation rating scales are limited by the length of observation they require, their need for participation by the patient, complexity in scoring, and a lack of validity in this setting and population. The purpose of this study was to psychometrically evaluate and refine an observation-based agitation scale for use with emergency department acute psychiatric patients. Using a methodological design, the 21-item Agitation Severity Scale was utilized to assess 270 adult psychiatric patients in the emergency setting in a prospective, observational fashion. Reliability analysis, item analysis, exploratory factor analysis, and validity assessments were completed. The relationship between Agitation Severity Scale scores and scores on the previously established Overt Agitation Severity Scale was evaluated. The instrument was reduced to 17 items representing four factors (Aggressive Behaviors, Interpersonal Behaviors, Involuntary Motor Behaviors, and Physical Stance) that accounted for nearly 70% of observed variance, Cronbach\u27s α = 0.91. Evidence of internal consistency reliability, equivalence reliability, construct validity, and convergent validity was established. Through this study, the 17-item Agitation Severity Scale demonstrated acceptable levels of reliability and validity when used with acute psychiatric patients in the emergency setting. This instrument holds promise as a method of enhancing clinical communication about agitation, evaluating the efficacy of interventions aimed at decreasing agitation, and as a research tool
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Assessing Diabetes Distress in Emerging Adults With Type 1 Diabetes: Development and Validation of the Problem Areas in Diabetes-Emerging Adult Version
OBJECTIVES: Emerging adults (18 to 30 years of age) with type 1 diabetes experience suboptimal glycemic and psychological outcomes compared with other groups. The emotional burden of the unending self-care needs of diabetes management appears to be related to these poor health outcomes. However, there is no validated measure of this emotional burden in the developmental context of emerging adulthood. The primary aim of this study was to examine the psychometric properties of a new measure of diabetes distress in emerging adults with type 1 diabetes in the United States. METHODS: In this cross-sectional study, emerging adults with type 1 diabetes completed an online survey, including measures of diabetes distress, depressive symptomology and the newly developed measure, the Problem Areas in Diabetes-Emerging Adult version (PAID-EA). Participants also answered demographic and clinical outcomes questions. Internal consistency, reliability, construct validity and the underlying factor structure of the PAID-EA were assessed. RESULTS: Participants (N=287, 78% women) had a median age of 24 years, 43% were full-time students, 78% wore an insulin pump and 90% used a continuous glucose monitor. Mean self-reported glycated hemoglobin was 7.1%±1.2%. The PAID-EA demonstrated good internal consistency and reliability (Cronbach α=0.89), was composed of one component accounting for 29% of the observed variance and demonstrated construct validity as it was significantly correlated with known measures of similar constructs, and with glycated hemoglobin levels (ρ=0.20, p=0.001). CONCLUSIONS: The PAID-EA holds promise as a reliable and valid measure of diabetes distress in emerging adults
Dispelling the Myths Behind First-author Citation Counts
We 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
