Reaching older people with PA delivered in football clubs: the reach, adoption and implementation characteristics of the Extra Time Programme.
Background Older adults (OA) represent a core priority group for physical activity and Public Health policy. As a result, significant interest is placed on how to optimise adherence to interventions promoting these approaches. Extra Time (ET) is an example of a national programme of physical activity interventions delivered in professional football clubs for OA aged 55+ years. This paper aims to examine the outcomes from ET, and unpick the processes by which these outcomes were achieved. Methods This paper represents a secondary analysis of data collected during the evaluation of ET. From the 985 OA reached by ET, n=486 adopted the programme and completed post-intervention surveys (typically 12 weeks). We also draw on interview data with 18 ET participants, and 7 staff who delivered the programme. Data were subject to thematic analysis to generate overarching and sub themes. Results Of the 486 participants, the majority 95%, (n= 462) were White British and 59.7% (n=290) were female. Most adopters (65.4%/n=318) had not participated in previous interventions in the host clubs. Social interaction was the most frequently reported benefit of participation (77.2%, n=375). While the reach of the club badge was important in letting people know about the programme, further work enhanced adoption and satisfaction. These factors included (i) listening to participants, (ii) delivering a flexible age-appropriate programme of diverse physical and social activities, (iii) offering activities which satisfy energy drives and needs for learning and (iv) extensive opportunities for social engagement. Conclusions Findings emerging from this study indicate that physical activity and health interventions delivered through professional football clubs can be effective for engaging OA
An Analysis of Technological Components in Relation to Privacy in a Smart City
A smart city is an interconnection of technological components that store, process, and wirelessly transmit information to enhance the efficiency of applications and the individuals who use those applications. Over the course of the 21st century, it is expected that an overwhelming majority of the world’s population will live in urban areas and that the number of wireless devices will increase. The resulting increase in wireless data transmission means that the privacy of data will be increasingly at risk. This paper uses a holistic problem-solving approach to evaluate the security challenges posed by the technological components that make up a smart city, specifically radio frequency identification, wireless sensor networks, and Bluetooth. The holistic focus in turn permits a set of technical and ethical approaches that can combat malicious attacks and enhance data security across the networks that drive smart cities
Time-critical decentralised situational awareness in emergencies: An adversarial biosecurity scenario
Abstract Crises in a global setting of interdependencies call for time-critical coordinated responses. However, it is often the case that the mechanisms responsible for these actions do not agree across all their hierarchies. This can be roughly attributed to personal estimations of the situation and to social influence. An ensuing lack of consensus against crises can be dire and echo across entire populations. One such instance is the case of biosecurity threats. A particularly interesting class of threats lie within urban environments, which tend to fall within the scope of bad actors. With this work we aim to computationally contribute to the understanding of the dynamics of perceived danger formation among agents responsible for responding to ongoing biological attacks in urban settings. We assume this perception is a function of a personal estimation of local information about the danger and of social influence stemming from the agents in question framed in an agent-based model. The simulations point towards a high dependence of perceived dangers on the personal estimations of the agents. The conditions under which the perceived dangers deviate from the real ones are explored over a range of assumptions on personal measurements and several dispositions towards the influencing environment. The insight provided by these results at the individual and collective level set the tone for further investigation on such behavioural phenomena, providing a flexible computational framework addressing generic threats (true dangers) in a time-critical context
Texas Agricultural Organization Board Members Knowledge of and Information Sources for the 2002 Farm Bill
This study attempted to assess Texas agricultural board members’ knowledge levels of the 2002 Farm Bill and to explore perceived values of information sources used to learn about the farm bill. Selected Texas agricultural organization board members (70) were most knowledgeable about the crop insurance and direct payment programs, findings that parallel previous studies. Respondents were least knowledgeable about the food stamp program. Respondents identified the Cooperative Extension Service and farm publications as the most valuable information sources for learning about the 2002 Farm Bill. No significant relationships existed between respondents’ knowledge of the 2002 Farm Bill and their information sources. If agricultural communicators want to reach agricultural board members, they should communicate farm bill programs and issues using the Cooperative Extension Service, the Internet (agricultural sites), and farm publications
Selected College Students\u27 Knowledge and Perceptions of Biotechnology Issues Reported in the Mass Media
The purpose of this study was to determine college students\u27 awareness of and attitudes toward biotechnology issues reported in the mass media. Future agricultural communicators (N = 330) representing 11 land-grant universities in 10 states recorded their knowledge and perceptions of biotechnology issues as reported in the mass media. Respondents were mostly seniors (46%), female (55%), and considered themselves 8 average students (60%). Students achieved only 30% correct responses (M = 3.05) in a knowledge assessment of biotechnology practices, illustrating a lack of knowledge. However, nearly 84% of the respondents perceived their level of knowledge as average to high (24% perceived they possessed above-average scientific knowledge). Future agricultural communicators were somewhat accepting of biotechnology practices for genetically modified organisms involving plant life (M = 3.28), but viewed these same practices as somewhat unacceptable for use on humans (M = 1.84). Significant, low positive relationships existed between respondents\u27 perceived and assessed levels ofbiotechnology knowledge (r = .17) and between their assessed knowledge and acceptance of biotechnology practices (r = .16). Selected college students in the agricultural sciences have much less knowledge about biotechnology practices than what they believed to possess. Although correctable through increased study of biotechnology, this finding may pose serious problems for students choosing to communicate the science of biotechnology issues in the mass media. Agricultural communications faculty nationwide should analyze their curricula to determine if students are being given the opportunity to study biotechnology issues while learning how to communicate it to a larger audience
Hidden evidence of non-exponential nuclear decay
The framework to describe natural phenomena at their basics being quantum
mechanics, there exist a large number of common global phenomena occurring in
different branches of natural sciences. One such global phenomenon is
spontaneous quantum decay. However, its long time behaviour is experimentally
poorly known. Here we show, that by combining two genuine quantum mechanical
results, it is possible to infer on this large time behaviour, directly from
data. Specifically, we find evidence for non-exponential behaviour of alpha
decay of 8Be at large times from experiments.Comment: 12 pages LaTex, 3 figure
