Development and Validation of the Vending Evaluation for Nutrient-Density (VEND)ing Audit

Background: This paper describes the development and validation of the Vending Evaluation for Nutrient-Density (VEND)ing audit to comprehensively evaluate vended products based upon healthfulness, price and promotion, and machine accessibility. Methods: A novel vending nutrient-density score was created to determine the healthfulness of vended snack/beverage products. Field tested in United States colleges, VENDing audit (Σnutrient-density + 10 x % healthy products) and Support sub-scores (price + promotion + accessibility) were calculated for snack/beverage machines. Higher scores indicate more healthful vending options and supports for choosing healthfully. Nutrition Environment Measures Survey-Vending (NEMS-V) was used to validate the nutrient-density score for a sub-sample of machines. Sensitivity and specificity were computed by comparing the number of healthy snacks/beverages determined by NEMS-V and the VENDing nutrient-density scores. Results: Researchers conducted the VENDing audit on 228 snack/beverage vending machines at 9 universities within the United States and used both VENDing and NEMS-V on 33 snack and 52 beverage vending machines. Mean VENDing audit scores were 4.5 ± 2.0 (2.6, 3.4) and 2.6 ± 2.0 (0, 12) for snack/beverage machines, respectively. The number of products considered healthy assessed with both the VENDing nutrient-density scores and the NEMS-V were positively correlated for beverages (r = 0.687, p \u3c 0.001) and snacks (r = 0.366, p \u3c 0.05). The sensitivity was excellent for beverages (0.83) and moderate for snacks (0.69); while the specificity was moderate for both beverages (0.66) and snacks (0.50). Conclusions: The VENDing audit uses unique, valid, an

Redesign, Field-Testing, and Validation of the Physical Activity Campus Environmental Supports (PACES) Audit.

This paper describes the redesign, field-testing, and convergent validity of a practical tool-Physical Activity Campus Environmental Supports (PACES) audit. Methods. The audit includes two parts: (1) PACES-Programs, which is comprised of questions regarding populations served, fees, programs (recreation/fitness classes and intramurals), proximity, adequacy of facilities, and marketing, and (2) PACES-Facilities, which is comprised of questions regarding built environment (aesthetics, bike racks, stairs, and universal design), recreation equipment, staff, amenities, and access. Each item criterion is specifically scored using a five-point, semantic-differential scale ranging from limited to extensive environmental support. A few questions utilize select all that apply for a summed score. PACES training, interrater reliability, and data collection are all accessible via an online portal. PACES was tested on 76 college campuses. Convergent validity was examined by comparing the PACES-Programs questions to Healthy Campus Initiatives-Programs questions (HCI-Programs) and comparing the PACES-Facilities questions to questions contained in the Physical Activity Resource Assessment (PARA) Instrument. Statistical analyses included Cronbach\u27s alpha, ANOVA, latent profile analysis, and Spearman correlations. Results.The PACES-Programs audit includes 10 items for a potential total of 73 points (α = 0.72) and PACES-Facilities audit includes 15 items for a potential total of 77 points (α = 0.837). Most (77.8%) of the 153 facilities assessed scored in the most healthful range (20-42), which was mainly due to the extensiveness of the aerobic equipment/amenities and the competence/accessibility of staff. Significant differences in PACES-Total and PACES-Programs scores were associated with campus size and PACES-Facilities across regions. For the paired validation assessments, correlations were significant between PACES-Programs and HCI-Programs ((n=41) r=0.498, p \u3c 0.001) and PACES-Facilities and PARA (n=29) for both features (r=0.417, p=0.024) and amenities (r=0.612, p \u3c 0.001), indicating moderate convergent validity. Conclusion. The PACES audit is a valid, reliable tool for assessing the quality of recreation facilities and programs in a variety of college campus environments

eB4CAST Approach Improves Science Communication With Stakeholders in a College-Based Health Program

Communicating scientific results with community partners is often lacking in intervention programs, thus eB4CAST was developed to facilitate impact sharing. This article investigated using the eB4CAST dissemination tool to communicate impact from a campus-based obesity prevention program. Data from Get Fruved RCT university sites collected at baseline were used to generate eB4CAST reports. Experts (n = 13) and RCT sites (n = 15) were asked to provide feedback on eB4CAST reports based on appeal, understanding, and clarity. On all Likert items, participants rated above 7 on each (out of 10). Positive responses from open-ended questions included eB4CAST reports being clear, visually appealing, and aid in program understanding. Overall, eB4CAST was successful in relaying data and information for the Get Fruved program, thus a means for science communication that could be used in interventions. Utilizing infographics to report data and information is a feasible way to disseminate and communicate in a cost-effective, timely manner

Re-visioning ultrasound through women's accounts of pre-abortion care in England

Feminist scholarship has demonstrated the importance of sustained critical engagement with ultrasound visualizations of pregnant women’s bodies. In response to portrayals of these images as “objective” forms of knowledge about the fetus, it has drawn attention to the social practices through which the meanings of ultrasound are produced. This article makes a novel contribution to this project by addressing an empirical context that has been neglected in the existing feminist literature concerning ultrasound, namely, its use during pregnancies that women decide to terminate. Drawing on semi-structured interviews with women concerning their experiences of abortion in England, I explore how the meanings of having an ultrasound prior to terminating a pregnancy are discursively constructed. I argue that women’s accounts complicate dominant representations of ultrasound and that in so doing, they multiply the subject positions available to pregnant women

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

"We can remember it for you wholesale": Lessons of the broadcast blacklist

14 pagesThe following essay considers the ways in which the broadcast blacklist affected how media studies scholars think about and study the 1950s, as well how we understand the role of gender and family in 1950s popular culture. At the start of the 1950s--at the very moment in which television was emerging, in the words of blacklisted writer Shirley Graham DuBois, as "the newest, the most powerful, the most direct means of communication devised by Man ... .[whose] potentialities for Good or for Evil are boundless"--a massive ideological crackdown occurred in broadcasting (Graham 1964. By focusing on how the blacklist made struggles over gender, race, and class unspeakable in the new medium, this essays seeks to restore the memory of these struggles and their participants to accounts of the 1950s, to underscore the strategic manipulation of culture and memory by conservative forces, and to remind us just how crucial historical research is for media studies

“I Will Own You”: Accountability in Massively Multiplayer Online Games

15 pagesAlthough most massively multiplayer online games (MMOs) remain entrenched in a binary system of gendered avatars, the limited representational framework of avatar creation is only one among many different strategies for what sociologists refer to as “doing gender.” This essay explores how a doing gender approach might be useful for analyzing the interactive dimensions of gender play in the rich communicative environments of MMOs. Specifically, this essay explores how players do (or do not) hold one another accountable to sex category membership through their interactions, in so doing either reproducing or resisting normative forms of gender. A doing gender approach, I argue, holds out the promise of being held accountable to a different set of rules for doing gender—of doing gender differently or, in a more utopian sense, perhaps doing away with it altogether

The Broadcast 41: Women and the Anti- Communist Blacklist

At the dawn of the Cold War era, forty-one women working in American radio and television were placed on a media blacklist and forced from their industry. The ostensible reason: so-called Communist influence. But in truth these women — among them Dorothy Parker, Lena Horne, and Gypsy Rose Lee — were, by nature of their diversity and ambition, a threat to the traditional portrayal of the American family on the airwaves. This book from Goldsmiths Press describes what American radio and television lost when these women were blacklisted, documenting their aspirations and achievements. Through original archival research and access to FBI blacklist documents, The Broadcast 41 details the blacklisted women’s attempts in the 1930s and 1940s to depict America as diverse, complicated, and inclusive. The book tells a story about what happens when non-male, non-white perspectives are excluded from media industries, and it imagines what the new medium of television might have looked like had dissenting viewpoints not been eliminated at such a formative moment. The all-white, male-dominated Leave it to Beaver America about which conservative politicians wax nostalgic existed largely because of the forcible silencing of these forty-one women and others like them. For anyone concerned with the ways in which our cultural narrative is constructed, this book offers an urgent reminder of the myths we perpetuate when a select few dominate the airwaves
