The social value of anonymity on campus: a study of the decline of Yik Yak

ABSTRACT

This paper considers the social value of anonymity in online university student communities, through the presentation of research which tracked the final year of life of the social media application Yik Yak. Yik Yak was an anonymous, geosocial mobile application launched in 2013 which, at its peak in 2014, was used by around two million students in the US and UK. The research we report here is significant as a mixed method study tracing the final year of the life of this app in a large UK university between 2016 and 2017. The paper uses computational and ethnographic methods to understand what might be at stake in the loss of anonymity within university student communities in a datafied society. Countering the most common argument made against online anonymity – its association with hate speech and victimisation – the paper draws on recent conceptual work on the social value of anonymity to argue that anonymity online in this context had significant value for the communities that use it. This study of a now-lost social network constitutes a valuable portrait by which we might better understand our current predicament in relation to anonymity, its perceived value and its growing impossibility.     

Renaissance revelations: hub museums and online documentation

This review reflects on the response made within the English regions to the national strategy adopted for museums development in the Renaissance in the Regions programme. It considers the national data collection expectations and the actuality of the reporting/evaluation of the programme's management in different regions. A survey of the available regional documentation suggests a lack of consistency in available information and approach, and that review of the programme is welcome in order to establish baseline information for performance measurement.     

Intensity of Treadmill Training and its Effect on Body Composition in Rats

Abstract

The purpose of this study was to determine which of three intensities of treadmill training produced changes in body composition in rats as evidenced by body weight, percentage of fat and specific gravity. Subjects were 60 male Wistar rats 25 to 30 days old when obtained. They were randomly assigned to one of five groups: sedentary controls, spontaneously active controls, and three groups of rats forced to exercise on a treadmill at intensities of 75, 125 and 175 fpm. Forced exercise was applied three times a week for 8 weeks, after which measures of body weight, specific gravity, and percentage of body fat were obtained. Results indicated that the sedentary controls had significantly higher mean body weights than did those which exercised. Rats forced to exercise at 75 fpm had significantly lower specific gravity measures than rats trained at 125 fpm. Sedentary controls had lower specific gravity values than did all rats allowed to exercise. Intensity of treadmill training had no effect on percentage of body fat as determined chemically. However, exercise was effective in reduction of body fat.     

Differences in feeding ecology predict differences in performance between golden lion tamarins (Leontopithecus rosalia) and Wied’s marmosets (Callithrix kuhli) on spatial and visual memory tasks

Golden lion tamarins (Leontopithecus rosalia) and Wied’s marmosets (Callithrix kuhli) exhibited adaptive differences in performance on several distinct memory tasks. On both an open-field analogue of a radial arm maze and a spatial delayed matching-to-sample task, the marmosets performed better than the tamarins after short (5-min) retention intervals, but only the tamarins continued to perform above chance after long (24- or 48-h) retention intervals. The marmosets also required less training than the tamarins did to learn a color memory task, but again only the tamarins performed above chance when the retention interval was increased to 24 h. The results of these experiments are consistent with predictions based on knowledge of the feeding ecology of these species in the wild and raise the possibility that they possess different visuospatial memory abilities specialized for tracking the spatial and temporal distribution of their principal foods.
