Abstract

Analysis of overhead imagery using computer vision is a problem that has received considerable attention in academic literature. Most techniques that operate in this space are both highly specialised and require expensive manual annotation of large datasets. These problems are addressed here through the development of a more generic framework, incorporating advances in representation learning which allows for more flexibility in analysing new categories of imagery with limited labeled data. First, a robust representation of an unlabeled aerial imagery dataset was created based on the momentum contrast mechanism. This was subsequently specialised for different tasks by building accurate classifiers with as few as 200 labeled images. The successful low-level detection of urban infrastructure evolution over a 10-year period from 60 million unlabeled images, exemplifies the substantial potential of our approach to advance quantitative urban research., Comment: Submitted to journal 'Sustainable Cities and Society'

9. Participatory Theme Elicitation: Open Card Sorting for User Led Qualitative Data Analysis

Author

Best, Paul, Badham, Jennifer, McConnell, Tracey, and Hunter, Ruth F.

Abstract

Participatory Theme Elicitation (PTE) is a new approach to increasing user-involvement in qualitative data analysis. In this five-step method, participants independently identify themes in the data using open card sorting, and are supported in their development of a set of themes that reflect all participant views. We describe and evaluate PTE with a case study, where nine lay researchers identified five core themes in qualitative data from an online intervention with depressed adults. Total participation time was approximately 6 hours. Evaluation data revealed high levels of satisfaction with the PTE process and the themes generated. The strong commitment to public engagement in social science research and limited guidance on methods for effective participatory analysis of qualitative data highlight the value and growing need for robust standardised approaches such as PTE.

Abstract

Background: Social media public health campaigns have the advantage of tailored messaging at low cost and large reach, but little is known about what would determine their feasibility as tools for inducing attitude and behavior change. Objective: The aim of this study was to test the feasibility of designing, implementing, and evaluating a social media-enabled intervention for skin cancer prevention. Conclusions: Social media-disseminated public health messages reached more than 23% of the Northern Ireland population. A Web-based survey suggested that the campaign might have contributed to improved knowledge and attitudes toward skin cancer among the target population. Findings suggested that shocking and humorous messages generated greatest impressions and engagement, but information-based messages were likely to be shared most. The extent of behavioral change as a result of the campaign remains to be explored, however, the change of attitudes and knowledge is promising. Social media is an inexpensive, effective method for delivering public health messages. However, existing and traditional process evaluation methods may not be suitable for social media., Comment: 17 pages published in Journal of Medical Internet Research - JMIR Public Health Surveillance, March 2017

19. The tales of two cities: use of evidence for introducing 20 miles per hour speed limits in Edinburgh and Belfast (United Kingdom).

Abstract

Background: In 2016, large-scale 20 miles per hour speed limits were introduced in the United Kingdom cities of Edinburgh and Belfast. This paper investigates the role that scientific evidence played in the policy decisions to implement lower speed limits in the two cities. Methods: Using a qualitative case study design, we undertook content analysis of a range of documents to explore and describe the evolution of the two schemes and the ways in which evidence informed decision-making. In total, we identified 16 documents for Edinburgh, published between 2006 and 2016, and 19 documents for Belfast, published between 2002 and 2016. Findings: In both cities, evidence on speed, collisions and casualties was important for initiating discussions on large-scale 20 mph policies. However, the narrative shifted over time to the idea that 20 mph would contribute to a wider range of aspirations, none of which were firmly grounded in evidence, but may have helped to neutralize opposing discourses. Discussion and conclusions: The relationship between evidence and decision-making in Edinburgh and Belfast was neither simple nor linear. Widening of the narrative appears to have helped to frame the idea in such a way that it had broad acceptability, without which there would have been no implementation, and probably a lot more push back from vested interests and communities than there was.

33. Exploring Perceived Support of Postgraduate Medical Science Research Students

Author

McEvoy, Claire T., Hunter, Ruth F., Matchett, Kyle B., Carey, Linda, McKinley, Michelle C., McCloskey, Karen D., and Woodside, Jayne V.

Abstract

There is still much to learn about the support required by postgraduate research students, across academic disciplines, to facilitate successful completion of a research degree. The primary aim of this study was to explore postgraduate medical science research students' perceptions of academic and mentoring support at different stages during their degree programme. A second aim was to explore the feasibility and acceptability of peer mentoring as a strategy to enhance student support in this population. A mixed method study design was used. Students first completed an online questionnaire, which was then supplemented with focus group discussion to explore emergent findings in greater depth. The main results indicated that the nature and quality of academic supervision support have a significant influence on research student training and development. 'Functional' and 'relationship development' concepts of supervisory styles were highlighted as important aspects to perceived support in this research population. The main facilitators to enhance academic support were effective communication, project planning and timely feedback. There was a high degree of acceptability for a peer mentoring programme as a complementary approach to enhance student support. Peer mentoring psychosocial functions such as friendship, counselling and career guidance were considered potentially beneficial to enhancing student support. Students also discussed peer coaching as central to their learning and research skill development. This work is a useful starting point to explore perceptions of research student support in the target population. Further work is required to develop strategies to enhance student support in academic practice.

Abstract

Objective:The school food environment (SFE) is an ideal setting for encouraging healthy dietary behaviour. We aimed to develop an instrument to assess whole-SFE, test the instrument in the school setting and demonstrate its use to make food environment recommendations.Design:SFE literature and UK school food guidance were searched to inform instrument items. The instrument consisted of (i) an observation proforma capturing canteen areas systems, food presentation and monitoring of food intake and (ii) a questionnaire assessing food policies, provision and activities. The instrument was tested in schools and used to develop SFE recommendations. Descriptive analyses enabled narrative discussion.Setting:Primary schools.Participants:An observation was undertaken at schools in urban and rural geographical regions of Northern Ireland of varying socio-economic status (n 18). School senior management completed the questionnaire with input from school caterers (n 16).Results:The instrument captured desired detail and potential instrument modifications were identified. SFE varied. Differences existed between food policies and how policies were implemented and monitored. At many schools, there was scope to enhance physical eating environments (n 12, 67 %) and food presentation (n 15, 83 %); emphasise healthy eating through food activities (n 7, 78 %) and increase parental engagement in school food (n 9, 56 %).Conclusions:The developed instrument can measure whole-SFE in primary schools and also enabled identification of recommendations to enhance SFE. Further assessment and adaptation of the instrument are required to enable future use as a research tool or for self-assessment use by schools.
