Human response to vibration in residential environments

This paper presents the main findings of a field survey conducted in the United Kingdom into the human response to vibration in residential environments. The main aim of this study was to derive exposure-response relationships for annoyance due to vibration from environmental sources. The sources of vibration considered in this paper are railway and construction activity. Annoyance data were collected using questionnaires conducted face-to-face with residents in their own homes. Questionnaires were completed with residents exposed to railway induced vibration (N = 931) and vibration from the construction of a light rail system (N = 350). Measurements of vibration were conducted at internal and external positions from which estimates of 24-h vibration exposure were derived for 1073 of the case studies. Sixty different vibration exposure descriptors along with 6 different frequency weightings were assessed as potential predictors of annoyance. Of the exposure descriptors considered, none were found to be a better predictor of annoyance than any other. However, use of relevant frequency weightings was found to improve correlation between vibration exposure and annoyance. A unified exposure-response relationship could not be derived due to differences in response to the two sources so separate relationships are presented for each source.

Charities’ use of Twitter: exploring social support for women living with and beyond breast cancer

ABSTRACT Twitter is one social media platform that enables those experiencing breast cancer to access support from others. This study explores how cancer charities provide support to women living with and beyond breast cancer (LWBBC) through their Twitter feeds. Seven hundred and seventy-two tweets from seven purposively sampled cancer charities were used to explore Twitter posts made relating to social support. Two questions were posed: (1) what type of support is positioned by cancer charities on Twitter for women LWBBC and (2) what themes emerge from tweet content pertaining to support for women LWBBC? Using a peer-reviewed typology of ‘social support’ [Rui, J., Chen, Y., & Damiano, A. (2013). Health organizations providing and seeking social support: A twitter-based content analysis. Cyberpsychology, Behavior, And Social Networking, 16(9), 669–673. doi:10.1089/cyber.2012.0350], a deductive content analysis was utilised to identify informational, instrumental or emotional social support tweets (n = 199). Over half (56%) of tweets offered informational support; 27% provided or sought instrumental support and 18% related to emotional support. Interestingly, 74.3% (n = 573) of tweets were not related to providing or seeking social support. An inductive qualitative thematic analysis of the 199 tweets identified the focus (i.e., themes) of support. Three themes were identified: (1) raising awareness, (2) focusing on the future and (3) sharing stories. Cancer charities predominantly use Twitter to signpost women to informational resources and to seek instrumental support to meet charitable objectives. As the number of women LWBBC continues to increase, this study provides valuable insight into how charities represent themselves on Twitter in relation to the social support needs of women LWBBC.

Personalizing twitter communication: an evaluation of ‘rotation-curation’ for enhancing social media engagement within higher education

ABSTRACT Social media content generated by learning communities within universities is serving both pedagogical and marketing purposes. There is currently a dearth of literature related to social media use at the departmental level within Higher Education Institutions (HEIs). This study explores the multi-voiced interactions of a UK Psychology department’s ‘rotation curation’ approach to using Twitter. An in-depth analysis of a corpus of 4342 tweets by 58 curators (14 staff, 41 students, and 3 guest curators) was carried out using a combination of computer-assisted and manual techniques to generate a quantitative content analysis. The interactions received (e.g. retweets and favorites) and type of content posted (e.g. original tweets, retweets and replies) varied by curator type. Student curators were more likely to gain interactions from other students in comparison to staff. This paper discusses the benefits and potential limitations of a multi-voiced ‘rotation curation’ approach to social media management.
