Data to accompany evaluation of the first U.S. staple foods ordinance: Impact on nutritional quality of food retailer offerings, customer purchases and home food environments
No full textThe same data are provided in both .sas7bdat and .csv formats.Many lower-income and racially diverse communities in the U.S. have limited access to
healthy foods, with few supermarkets and many small convenience stores, which tend
to stock limited quantities and varieties of healthy foods. To address food access, in
2015 the Minneapolis Staple Foods Ordinance became the first policy requiring food
stores to stock minimum quantities and varieties of 10 categories of healthy
foods/beverages, including fruits, vegetables, whole grains and other staples, through
licensing. This study examined whether: (a) stores complied, (b) overall healthfulness
of store environments improved, (c) healthy customer purchases increased, and (d)
healthfulness of home food environments improved among frequent small store
shoppers. Data for this natural (or quasi) experiment were collected at four times: pre-policy
(2014), implementation only (no enforcement, 2015), enforcement initiation (2016) and
continued monitoring (2017). In-person store assessments were conducted to evaluate
food availability, price, quality, marketing and placement in randomly sampled food
retailers in Minneapolis (n=84) and compared to those in a nearby control city, St. Paul,
Minnesota (n=71). Stores were excluded that were: supermarkets, authorized through
WIC (Special Supplemental Nutrition Program for Women, Infants, and Children), and
specialty stores (e.g., spice shops). Customer intercept interviews were conducted
with 3,039 customers exiting stores. Home visits, including administration of home food
inventories, were conducted with a sub-sample of frequent shoppers (n=88).
Overall, findings indicated significant improvements in healthy food offerings by
retailers over time in both Minneapolis and St. Paul, with no significant differences in
change between the two cities. Compliance was low; in 2017 only 10% of Minneapolis
retailers in the sample were fully compliant, and 51% of participating Minneapolis
retailers met at least 8 of the 10 required standards. Few changes were observed in
the healthfulness of customer purchases or the healthfulness of home food
environments among frequent shoppers, and changes were not different between
cities. This study is the first evaluation of a local staple foods ordinance in the U.S. and reflects
the challenges and time required for implementing such policies.National Institute of Diabetes and Digestive and Kidney Diseases (R01DK104348)Centers for Disease Control and Prevention (U48DP005022)Eunice Kennedy Shriver National Institute of Child Health and Human Development (U54HD070725)National Institutes of Health (5R25CA163184)National Center for Advancing Translational Science (UL1TR000114)Laska, Melissa N; Caspi, Caitlin E; Lenk, Kathleen; Moe, Stacey G; Pelletier, Jennifer E; Harnack, Lisa J; Erickson, Darin J.

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
