“Body goals”: Exposure to idealized, popular media images can affect body satisfaction ratings

College students are exposed to media many times throughout their day. Studies have shown that there are many negative correlations between students and their comparison of their bodies to others. In this study, it was tested to see if viewing mass media images for a while can affect the way people rate their body satisfaction and whether or not they would change their body. There were 20 people tested in this study. There were 10 people in the control group, and 10 people in the experimental group. The experimental group was required to watch a slideshow with 4 different pictures of health magazine covers then take a short body satisfaction survey, whereas the control group just completed the survey. It was found that there was no significance between the two groups and their group means were basically the same. Lack of significance could be caused by the small sample size or lack of time spent looking at the media images. This study can be built on in the future to add more people and expand to a more diverse sampling. In general, this study has not compared to other studies on the same topic but the method can be used to form a different study

Global-Scale Patterns of Forest Fragmentation

We report an analysis of forest fragmentation based on 1-km resolution land-cover maps for the globe. Measurements in analysis windows from 81 km 2 (9 x 9 pixels, "small" scale) to 59,049 km 2 (243 x 243 pixels, "large" scale) were used to characterize the fragmentation around each forested pixel. We identified six categories of fragmentation (interior, perforated, edge, transitional, patch, and undetermined) from the amount of forest and its occurrence as adjacent forest pixels. Interior forest exists only at relatively small scales; at larger scales, forests are dominated by edge and patch conditions. At the smallest scale, there were significant differences in fragmentation among continents; within continents, there were significant differences among individual forest types. Tropical rain forest fragmentation was most severe in North America and least severe in Europe-Asia. Forest types with a high percentage of perforated conditions were mainly in North America (five types) and Europe-Asia (four types), in both temperate and subtropical regions. Transitional and patch conditions were most common in 11 forest types, of which only a few would be considered as "naturally patchy" (e.g., dry woodland). The five forest types with the highest percentage of interior conditions were in North America; in decreasing order, they were cool rain forest, coniferous, conifer boreal, cool mixed, and cool broadleaf
