Finding provenance data in social media

Description

A statement appearing in social media provides a very significant challenge for determining the provenance of the statement. Provenance describes the origin, custody, and ownership of something. Most statements appearing in social media are not published with corresponding provenance data. However, the same characteristics that make the social media environment challenging, including the massive amounts of data available, large numbers of users, and a highly dynamic environment, provide unique and untapped opportunities for solving the provenance problem for social media. Current approaches for tracking provenance data do not scale for online social media and consequently there is a gap in provenance methodologies and technologies providing exciting research opportunities. The guiding vision is the use of social media information itself to realize a useful amount of provenance data for information in social media. This departs from traditional approaches for data provenance which rely on a central store of provenance information. The contemporary online social media environment is an enormous and constantly updated "central store" that can be mined for provenance information that is not readily made available to the average social media user. This research introduces an approach and builds a foundation aimed at realizing a provenance data capability for social media users that is not accessible today.

A cross-cultural study of the U.S. and Taiwanese children's visual image reading

Description

This study aimed to understand, compare and describe details about U.S children and Taiwanese children's visual image reading. The researcher interviewed thirty children ages 8 to 10 in the state of Arizona and Taiwan. The researcher employed quantitative and qualitative methods to analyze the data. The analysis using these two methods provided different ways of comprehending the data. The results showed that the two groups of children's image reading did not have statistically significant differences in most categories; but there were demonstrable trends and viewpoints employed when both groups of children explained the details of the images. First, the children expressed what they saw in the images in six ways. The U.S. children were more able to describe contexts with self-experiences/opinions and/or associations than the Taiwanese children. Second, when interpreting the meanings, the Taiwanese children understood the concepts of the images better than the U.S. group. The U.S. children were more critical and expressed self-opinions/associations more. Third, when asked preferences, the U.S. children paid more attention to identify their favorites and express feeling the images brought to them. The Taiwanese children cared more about style and form. Fourth, when judging the images, the U.S. children emphasized the artist's devotion to creating while Taiwanese children considered the form, composition, colors, structure, design, and composition. The results also indicated that the children decided their preferences and their judgments of artworks might be based on multiple viewpoints instead of a single one, especially for the Taiwanese children. Some cultural differences between the two groups of children and their image readings were presented, such as, cultural differences made children have different learned symbolism.

SCAT: Short-form Corner Store Audit Tool

Description

Programs such as the Healthy Corner Store Initiative have been widely adopted in recent years to increase the availability of healthy foods in small retail food stores. Valid and reliable measures are necessary to evaluate the effectiveness of these programs. The validated instruments currently available for assessments require in-person evaluations, with surveys taking up to 30 minutes per store to complete. This instrument was developed by researchers at Arizona State University to simplify the process of evaluating the effectiveness of healthy store interventions, and to enable community partners and practitioners to conduct their own evaluations of food access. The SCAT was validated against an adapted version of the Nutrition Environment Measures Survey for Corner Stores, and tested for feasibility of use over the telephone. The SCAT was found to discriminate between corner stores in the top 20% of healthfulness scores from those in the lower 80% with 89% accuracy.

In 2015 a panel of experts was convened by Healthy Eating Research, a program of the Robert Wood Johnson Foundation, to establish a set of minimum guidelines small retail food stores could reach to be classified as meeting basic or preferred stocking levels. Work is currently in progress to assess how the SCAT scores correlate with basic and preferred levels.
