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
Informed Decision Making for Percutaneous Coronary Intervention for Stable Coronary Disease
No full textIMPORTANCE:
Patients with stable coronary disease undergoing percutaneous coronary intervention (PCI) are frequently misinformed about the benefits of PCI. Little is known about the quality of decision making before angiography and possible PCI. OBJECTIVE:
To assess the quality of informed decision making and its association with patient decisions. DESIGN, SETTING, AND PARTICIPANTS:
We performed a cross-sectional analysis of recorded conversations between August 1, 2008, and August 31, 2012, among adults with known or suspected stable coronary disease at outpatient cardiology practices. MAIN OUTCOMES AND MEASURES:
Presence of 7 elements of informed decision making and the decision to undergo angiography and possible PCI. RESULTS:
Of 59 conversations conducted by 23 cardiologists, 2 (3%) included all 7 elements of informed decision making; 8 (14%) met a more limited definition of procedure, alternatives, and risks. Specific elements significantly associated with not choosing angiography and possible PCI included discussion of uncertainty (odds ratio [OR], 20.5; 95% CI, 2.3-204.9), patient\u27s role (OR, 5.3; 95% CI, 1.3-21.3), exploration of alternatives (OR, 9.5; 95% CI, 2.5-36.5), and exploration of patient preference (OR, 4.8; 95% CI, 1.2-19.4). Neither the presence of angina nor severity of symptoms was associated with choosing angiography and possible PCI. In a multivariable analysis using the total number of elements as a predictor, better informed patients were less likely to choose angiography and possible PCI (OR per additional element, 3.2; 95% CI, 1.4-7.1; P = .005). CONCLUSIONS AND RELEVANCE:
In conversations between cardiologists and patients with stable angina, informed decision making is often incomplete. More complete discussions are associated with patients choosing not to undergo angiography and possible PCI
The Impact of an Institutional Grant Program on the Economic, Social, and Cultural Capital of Women Researchers
No full textIntroduction: Early funding can have significant impact on a researcher\u27s career. However, funding is not equal for men and women. Not only do female researchers apply for fewer grants than men, but they also experience a lower success rate when they do. The Zucker Grant Program (ZGP) was established in 2000 to promote the early success of women researchers. The purpose of this evaluation is to support other institutions hoping to grow the research careers of women scientists. Methods: This program evaluation reviewed the first 16 years of the program\u27s history. Our mixed-methods, outcomes-based evaluation had four phases: (I) interviews with key stakeholders, (II) development and distribution of a survey to ZGP recipients, (III) focus groups and interviews with ZGP recipients, (IV) document analysis from the ZGP Center and the Tufts University School of Medicine (TUSM) Development Office. This article reports on the qualitative data collection and analysis. Results: Between 2000 and 2016, US$377,050 was awarded for 142 recipients. Qualitative data revealed how grant funding was critical to support pilot data in awardees\u27 research to inform extramural grant applications. However, the program evaluation also identified effects on awardees\u27 confidence as researchers and connection to a community. Conclusion: Outcomes are interpreted through the framework of Bourdieu\u27s three forms of capital, including economic, social, and cultural capital. Viewed through this framework, they provide a critical infrastructure to the development and success of early career female investigators. This work offers other institutions a framework to consider when establishing intramural funding and support programs for their early career investigators
How cardiologists present the benefits of percutaneous coronary interventions to patients with stable angina: a qualitative analysis
No full textIMPORTANCE:
Patients with stable coronary artery disease (CAD) attribute greater benefit to percutaneous coronary interventions (PCI) than indicated in clinical trials. Little is known about how cardiologists\u27 presentation of the benefits and risks may influence patients\u27 perceptions. OBJECTIVES:
To broadly describe the content of discussions between patients and cardiologists regarding angiogram and PCI for stable CAD, and to describe elements that may affect patients\u27 understanding. DESIGN, SETTING, AND PARTICIPANTS:
Qualitative content analysis of encounters between cardiologists and patients with stable CAD who participated in the Verilogue Point-of-Practice Database between March 1, 2008, and August 31, 2012. Transcripts in which angiogram and PCI were discussed were retrieved from the database. Patients were aged 44 to 88 years (median, 64 years); 25% were women; 50% reported symptoms of angina; and 6% were taking more than 1 medication to treat angina. MAIN OUTCOMES AND MEASURES:
Results of conventional and directed qualitative content analysis. RESULTS:
Forty encounters were analyzed. Five major categories and subcategories of factors that may affect patients\u27 understanding of benefit were identified: (1) rationale for recommending angiogram and PCI (eg, stress test results, symptoms, and cardiologist\u27s preferences); (2) discussion of benefits (eg, accurate discussion of benefit [5%], explicitly overstated benefit [13%], and implicitly overstated benefit [35%]); (3) discussion of risks (eg, minimization of risk); (4) cardiologist\u27s communication style (eg, humor, teach-back, message framing, and failure to respond to patient questions); and (5) patient and family member contributions to the discussion. CONCLUSIONS AND RELEVANCE:
Few cardiologists discussed the evidence-based benefits of angiogram and PCI for stable CAD, and some implicitly or explicitly overstated the benefits. The etiology of patient misunderstanding is likely multifactorial, but if future quantitative studies support the findings of this hypothesis-generating analysis, modifications to cardiologists\u27 approach to describing the risks and benefits of the procedure may improve patient understanding
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
