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
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
Using cultural-historical activity to study clinical reasoning in context
Get PDFThe aim of this paper is to describe sources of conflict and congruence in critical areas of practice with caregivers of persons with dementia, using cultural-historical activity theory as an analytic framework. Findings are drawn from an ethnographic study that described the context of occupational therapists’ (OTs’) clinical reasoning in a funded, home-based environmental skill-building program designed to help caregivers manage the daily care of a family member with dementia. Data were gathered through observation of intervention sessions, debriefing sessions, semi-structured interviews with therapists, and review of intervention documentation. Primary sources of conflict and congruence within the identified practice context included conflicts between therapists and caregivers concerning which environmental strategies were best for addressing problems in caregiving and expectations regarding OTand caregiver roles. Areas of congruence included the fit between intervention protocols used to guide treatment and the approaches therapists developed to help caregivers modify care receivers’ living environments. The study revealed the complexity of OT practice and demonstrated that practice contexts can be systematically analyzed using cultural-historical activity theory to determine key factors influencing clinical reasoning. The approach also presents an alternative perspective on clinical reasoning that more directly integrates clients/caregivers and therapists as co-constructors of OT intervention
Factors influencing appraisal of upset in black caregivers of persons with Alzheimer disease and related dementias
Get PDFBlack caregivers of persons with Alzheimer disease and related dementias (ADRD) have demonstrated significantly lower levels of stress and burden than white caregivers, as measured by instruments that assess caregiving burden and stressfulness of specific problem behaviors. However, the reasons for reported differences are unclear and cannot be attributed solely to race. This descriptive study used content analysis to compare black caregivers’ descriptions and interpretations of responses to memory and behavioral issues of relatives with ADRD to 11 explanations for lower levels of upset proposed in the caregiving literature. Findings confirmed only two explanations from the literature, social support and religious orientation, as factors that influenced appraisal of upset. Two new themes emerged, categorized as Making Sense and Using Strategies, as explanatory frameworks. Findings extend current knowledge of black caregivers’ emotional responses to caregiving and support the need for future study of the ways in which particular ethnic and racial groups experience caregiving. Understanding the meaning of appraisals may enable service providers and program developers to tailor services and interventions to support the efforts of black and other minority caregivers
Computer-assisted instruction as a learning resource for applied anatomy and kinesiology in the occupational therapy curriculum.
Get PDFOBJECTIVES: The purpose of these studies was to examine the learning outcomes of a computer-assisted instruction (CAI) tutorial in applied anatomy and kinesiology for occupational therapy students and to determine its applicability for use in two university settings.
METHOD: Two separate pilot studies were conducted at two universities. In each study, the learning outcomes of an experimental group of occupational therapy students using a CAI program and a control group using books to study the same material were compared. Learning outcomes were assessed with post-test achievement test scores on an applied anatomy and kinesiology test and responses to an attitude questionnaire with Likert-scale items and open-ended questions.
RESULTS: There was no significant difference in the means on achievement test scores for the experimental and control groups in the first pilot study. In the second study, the CAI group scored significantly higher on the achievement test than the control group. In both pilot studies, subjects displayed significantly more positive attitudes toward the CAI program as a learning tool than they did toward traditional self-study with books.
CONCLUSION: A CAI program in applied anatomy and kinesiology can be an effective supplemental resource for occupational therapy students and can offer a learning experience that students value and perceive as helpful. Establishment of clear learning objectives, use of a theoretical base to design instruction, and development and testing in different educational settings can help improve the quality of CAI programs and ensure their relevance to other curricula
