British surfers and their attitudes and values toward the environment

The purpose of this study was to examine the attitudes of British surfers toward their environment. Eight surfers were interviewed and their views analyzed using an inductive thematic analysis to explore their perceptions of the factors that have influenced their engagement in proenvironmental behaviors. The findings suggest that surfers (in this sample), while motivated to engage in proenvironmental behaviors, are also influenced by a range of factors and appear to be primarily motivated by their identification and a need to maintain their experience of that sport. This reveals an inherent dilemma. Through their sport surfers are able to observe the effects of environmental degradation on the environment (e.g., polluted water), the ecosystem, and on their personal health. However, they are also aware of the trade-offs required in pursuing their sport that may damage the environment (e.g., toxic material involved in sport kit manufacture). When questioned, surfers stated they would be unwilling to give up their sport even at the cost of the environment in which those activities are experienced. This highlights a possibly common problem among environmentally minded outdoor enthusiasts: when do personal benefits outweigh the responsibilities of environmental stewardship? The value of these findings is discussed in relation to the promotion of proenvironmental behaviors and engagement with proenvironmental groups

Electron Acceleration by Multi-Island Coalescence

Energetic electrons of up to tens of MeV are created during explosive phenomena in the solar corona. While many theoretical models consider magnetic reconnection as a possible way of generating energetic electrons, the precise roles of magnetic reconnection during acceleration and heating of electrons still remain unclear. Here we show from 2D particle-in-cell simulations that coalescence of magnetic islands that naturally form as a consequence of tearing mode instability and associated magnetic reconnection leads to efficient energization of electrons. The key process is the secondary magnetic reconnection at the merging points, or the `anti-reconnection', which is, in a sense, driven by the converging outflows from the initial magnetic reconnection regions. By following the trajectories of the most energetic electrons, we found a variety of different acceleration mechanisms but the energization at the anti-reconnection is found to be the most important process. We discuss possible applications to the energetic electrons observed in the solar flares. We anticipate our results to be a starting point for more sophisticated models of particle acceleration during the explosive energy release phenomena.Comment: 14 pages, 12 figures (degraded figure quality), 1 table.

The egalitarian effect of search engines

Search engines have become key media for our scientific, economic, and social activities by enabling people to access information on the Web in spite of its size and complexity. On the down side, search engines bias the traffic of users according to their page-ranking strategies, and some have argued that they create a vicious cycle that amplifies the dominance of established and already popular sites. We show that, contrary to these prior claims and our own intuition, the use of search engines actually has an egalitarian effect. We reconcile theoretical arguments with empirical evidence showing that the combination of retrieval by search engines and search behavior by users mitigates the attraction of popular pages, directing more traffic toward less popular sites, even in comparison to what would be expected from users randomly surfing the Web.Comment: 9 pages, 8 figures, 2 appendices.

Bottom-up radio: creating a new media format using living lab research

This study resulted in the creation of a new media format for urban youth, adopting a living lab-approach, as current studies have shown that this group is currently not reached with the contemporary media offer. Living lab research is a state-of-the art methodology that aims at involving end-users in the innovation process over a longer time span, combining both quantitative and qualitative research techniques and tools. In a first phase, a panel of urban youngsters was created using an intake survey (N=290). These data were analyzed resulting in three distinct types of urban youngsters. In a second phase, a qualitative research trajectory was organized in order to refine the three profiles and get an insight in their media use, digital skills, media preferences and needs with regards to the current media offer. Research methods during this phase included diary studies, participatory observation during workshops and probe research. In a third phase, co-creation sessions were organized with youngsters from the urban panel in order to get feedback on a concept that was iteratively developed during the first two phases of the project. Results show that mobile devices and social media are important for these urban youngsters and that most of these youngsters have quite some creative skills. Radio seems to be a less popular medium, although they spend a significant amount of time listening to music. Further, results show that these youngsters are in need of a platform which stimulates community building and offers a space to express their creativity. A third requirement for the development of a new media format that would meet the needs of these youngers is a format that provides space for local elements and niche markets. This all resulted in the launch of Chase, an urban, crowdsourced radio station

The four powers of design: A value model in design management

This analysis proposes a framework to bridge the gap between the world of designers and the world of managers. Illuminating her thesis with examples from Steelcase, Decathlon, and other companies, Brigitte Borja de Mozota parallels design's ability to differentiate, integrate, transform, and contribute to the enterprise and bottom-line results with a corporate focus on markets, processes, talent, and finances

The dark side of flow:a qualitative study of dependence in big wave surfing

Flow has been described within sport psychology as an optimal state underpinning peak performance. However, the consequences of experiencing flow may not always be beneficial. One negative consequence might be that of contributing to dependence on the activity that interacts with, or is associated with, the flow experience. This study explored the dichotomous consequences of flow, using case studies of big wave Surfers. Fifteen elite surfers completed in-depth, semistructured interviews. It seems clear from the results that the surfers experienced positive consequences of flow. However, they also exhibited symptoms of dependence on surfing. It is suggested that there may be air association between the experience of dimensions of flow and the compulsion to engage in an activity. Some specific recommendations for further research into the relationship between flow and exercise dependence are made
