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

Thinking Outside of the Lunchbox: Exploring Competing Narratives in the Corvallis 509J District School Lunch Policies
Get PDFAt its inception in 1946, the United States’ National School Lunch Program (NSLP) was promoted as a success story; a boon for families navigating poverty, a means of buoying food prices by absorbing farm surplus, and a treatment for hunger in some of our country’s most vulnerable populations. Government subsidies were presented as a useful policy prescription, and commodities such as corn, soy, and canned foods were deemed acceptable nutrition for growing bodies.
Sixty years later school food policy narratives have changed. U.S. communities advocate for fresher ingredients and fewer preservatives, along with culturally relevant options, and food education that fits into a healthy and sustainable lifestyle. In the Corvallis, Oregon school district, conversation about school lunch has become contentious leading to lagging participation rates and a budget shortage. In the face of conflicting narratives, local stakeholders have engaged in activism and district administrators have sought community consensus.
Methodologically this paper employs qualitative methods. Leveraging a series of qualitative interviews and a brief survey with elite decision makers and district families, this research evaluates narrative variation among stakeholders and across cultural groups to determine what variation manifests in school lunch policies and what policy implications that variation has. Theoretically this research draws on the Narrative Policy Framework (NPF) and Cultural Theory (CT) to identify the distinct perspectives shaping competing narratives in the district’s school lunch environment. Research findings are explored within the context of local school lunch advocacy efforts and in light of extant NPF literature.

A narrative policy framework analysis of food assistance programs in Oregon
No full textWhile policies like the Supplemental Nutrition Assistance Program (SNAP) and National School Lunch Program (NSLP) are complex, we can leverage policy narratives to order that complexity and help distill meaning. We can also examine food policy narratives to help identify policy solutions for families navigating poverty and subsistence living. This research investigates SNAP and NSLP policy narratives using two theoretical approaches. First, I leverage the Narrative Policy Framework (NPF) which provides the theoretical tools to describe and compare the structure of stakeholder food stories and identify narrative characters, plots, and morals of the story. Secondly, I employ Cultural Theory (CT) to help understand how people systematically make sense of the content of their stories. Together, the NPF and CT allow me to examine how the structure and content of food policy stories vary, and what this variation means to the policy process.
Paper 1 leverages participant observation, qualitative interviews, and survey data to explore Corvallis, Oregon NSLP policy, contrasting local and national policy perspectives to identify distinct food policy narratives among Corvallis, Oregon stakeholders and across cultural groups. This paper’s main findings were a predominantly egalitarian worldview among Corvallis stakeholders whose narratives feature children as victims, with community institutions and advocates in the roles of the heroes and/or villains. Sustainability and the value of market forces were also identified as key themes in local and national school lunch narrative plots and morals.
Paper 2 employs similar methods and analysis tools used for paper 1 but includes an expanded sample frame to include SNAP program beneficiaries and administrators from Lincoln, Benton, and Linn, Oregon counties. Paper 2 is an investigation of policy narratives surrounding the Covid-19 SNAP temporary Emergency Allotments (EAs) policy termination. I define this policy termination as a ‘policy cliff,’ as it is the time at which the economic stimulus abruptly ended. Key findings include stakeholders with a shared egalitarian-leaning worldview and how the expanded investment in food programs during the Covid-19 public health emergency helped reduce food insecurity and aid families navigating poverty. Another key finding was that program beneficiaries and administrators faced the policy cliff together, facing down the incoming crisis with various motivations, perspectives, and tools which impacted policy learning.
Paper 3 builds on the data from papers 1 and 2, using a similar theory and data analysis method. I applied a lens of rural poverty and food insecurity to student families, with the goal of qualifying and quantifying the rural and non-rural narratives observed in my field research and interviews across ODHS District 4. Findings suggest that CT worldviews expressed by both rural and non-rural interviewees are profoundly egalitarian. Thematic variations in the egalitarian narratives emerged using a CT weighted measure and in discussions of geographic proximity to food program access and distance to full-service grocery stores.
Together these papers contribute to the study of food-focused social policy narratives, comparing a sample population of SNAP and NSLP program advocates, beneficiaries, and administrators from across Oregon Department of Human Services (ODHS) District 4, spanning Lincoln, Benton, and Linn counties. My research goals were exploratory and descriptive. Resultant data may be used to inform future ODHS and school district policy processes
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
