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

Collaborative Learning Among Health Care Practices and Systems to Improve Patient-Centered Care
Get PDFDespite a rich literature examining the application of organizational learning to engineering and management contexts, learning in the health care sector has received far less empirical attention. These papers collectively address which organizational factors are precursors to learning within quality improvement collaboratives (QICs) and how participation in QICs impacts patient-centered outcomes. The first paper examines the organizational attributes associated with physician practices’ propensity to participate in QICs. The second paper explores the implementation of a shared decision making intervention within the High Value Healthcare Collaborative (HVHC) and investigates its impact upon hip and knee osteoarthritis patients' treatment preferences and decision certainty. Finally, the third paper interrogates whether surgical utilization varies across patients engaged in shared decision making compared with patients receiving usual care within HVHC

Racism, Illegality, and Population Health: Mechanisms, Interventions, & Community-Engaged Research
No full textThis dissertation examines how immigration status and racial stratification shape social experiences and public policies that impact mental health outcomes. My dissertation spans two areas: (1) clarifying the mental health consequences of social stratification that differentially distribute risks and opportunities based on immigration status and race/ethnicity and (2) adapting, implementing, and evaluating digital health innovations that address mental health disparities among U.S. Latinxs. The first study uses primary data to examine perceptions of legal vulnerability—or the positionality in U.S. society that inflicts physical/emotional distress on immigrants through exclusionary policies/practices—among undocumented men from Mexico and Central America working in the informal labor market. I examine the relationship between legal vulnerability and risk of depression and anxiety symptoms among Latinx day laborers. The second study examines the relationship between race/ethnicity (a proxy for racial stratification), frontline work, and adverse pandemic-related social and economic conditions, which I denote as “pandemic stressors.” I assess whether racial differences in pandemic-related stressors existed among workers and whether engaging in essential frontline work was associated with more pronounced pandemic-related stress for Latinx and Black workers compared to White workers. Given the limited availability of language-concordant and culturally competent mental health care and the inequitable impact of the pandemic on the well-being of U.S. Latinxs, the third study focuses on adapting, implementing, and evaluating a text messaging cognitive behavioral therapy intervention, StayWell at Home (StayWell), to address depressive symptoms during the pandemic

The Adoption and Use of Health Information Technology in Three Settings
Get PDFHealth information technology (IT) has become an increasingly common part of the U.S. healthcare system. This three-paper dissertation examines barriers, facilitators, and correlates of health IT adoption and impacts of health IT use in several important settings. The first paper examines the impact of electronic warnings in diverting non-indicated prescriptions in ambulatory settings. Specifically, we measured the incidence of antibiotic prescriptions for acute bronchitis and upper respiratory infections using a nationally-representative dataset. We found evidence that, overall, electronic warnings reduce the likelihood of antibiotic prescription receipt by about 20%. However, despite the recent increase in use of electronic warnings, antibiotic prescribing is not on the decline, suggesting that electronic warnings alone may not be sufficient to eliminate non-indicated prescriptions.The second paper provides the first cross-year comparison of the use of electronic health records (EHRs) at local public health departments (LHDs) in the U.S. Using 2005 and 2010 data from the National Association of City and County Health Officials, we found that EHR usage has remained relatively steady at local public health departments. There is substantial churn, however, with approximately one-quarter of the sample adopting EHRs and another fifth of the sample discontinuing use of EHRs. Our study suggests that EHRs are not diffusing throughout LHDs as they are in other healthcare settings. Our results highlight departmental characteristics under which EHRs are commonly used and suggest potential places, such as poor or rural areas, where use of EHRs may be lower than expected.The third paper examines participation in health information exchange (HIE) in two settings where HIEs have proven slow to diffuse--smaller-sized physician practices and federally qualified health centers (FQHCs). We conducted key informant interviews with stakeholders at practices and clinics. Our results suggest barriers to HIE adoption that exist at three levels--regional (e.g., existence of other area-level exchanges; number, type, and size of partner organizations), inter-organizational (e.g., strong relationships with exchange partners; achieving a critical mass of users), and intra-organizational (e.g., type of electronic medical record used; integration into organization's workflow). While some of these factors may be modifiable by health care organizations, limited solutions to overcome these barriers currently present a major challenge to the broad and effective use of HIE
