Mobility as a key modern phenomenon can be seen in multiple ways and this article raises the question of how mobility becomes visible and real through diverse ways of seeing mobility. Mobility's different aspects appear and take place in particular spatial settings under the workings of diverse forms of power, and recognizing this informs us about the making of spatialised mobility. It is shown how mobility intermingles with perceptions, experiences and desires of the modern self. Such workings of power relate, among other things, to framing and imagining, practising and experiencing mobility. Capturing ways of seeing mobility thus widens our language for engaging with questions of mobility and its political and social reality and possible futures.
Many governments attempt to improve cycling safety to reduce the number of bicycle crashes and encourage people to take up cycling. The Netherlands is a world leader in bicycle use and safety. This paper explores how the Netherlands achieved an 80% reduction in the number of cyclists killed (predominantly bicycle-motor vehicle crashes) per billion bicycle kilometres over a thirty year period. Factors found to contribute to this improvement include the establishment of a road hierarchy with large traffic-calmed areas where through traffic is kept out. A heavily used freeway network shifts motor vehicles from where cycling levels are high. This reduces exposure to high-speed motor vehicles. Separated bicycle paths and intersection treatments decrease the likelihood of bicycle-motor vehicle crashes. The high amount of bicycle use increases safety as a higher bicycle modal share corresponds with a lower share of driving and greater awareness of cyclists among drivers. Low cycling speed was also found to contribute to the high level of cycling safety in the Netherlands.
As foreign language education moves toward proficiency‐based teaching and testing, few studies have looked systematically at its effects on student performance, classroom methods and materials, teacher expectations, and program administration, particularly at the secondary level. The study reported here examines the effects of district‐wide ACTFL Oral Proficiency Interview (OPI) testing. Specifically, the study asks, “Do students who perform well on the OPI also perform well on more traditional measures of student success?” and “What other effects, if any, does oral proficiency testing have on a foreign language program?” Multivariate analyses of variance were performed on scores from the OPI and the subscales of the College Board Foreign Language Achievement Test from 492 third, fourth, and fifth year high school foreign language students. Qualitative data include information from interviews, observations, and a questionnaire distributed to administrators, teachers and students. Significant correlations were found between student performance at the higher levels of the OPI and on the achievement tests. Furthermore, the benefits of the oral proficiency testing program extended beyond student performance to the sense of common direction it provided to teachers and programs.
Urbanization is a global trend, and consequently the quality of urban environments is increasingly important for human health and wellbeing. Urban life-style is typically associated with low physical activity and sometimes with high mental stress, both contributing to an increasing burden of diseases. Nature-based solutions that make effective use of ecosystem services, particularly of cultural ecosystem services (CES), can provide vital building blocks to address these challenges. This paper argues that, the salutogenic, i.e. health-promoting effects
Abstract. Residential wood combustion (RWC) is an important contributor to air quality in numerous regions worldwide. This study is the first extensive evaluation of the influence of RWC on ambient air quality in several Nordic cities. We have analysed the emissions and concentrations of PM2.5 in cities within four Nordic countries: in the metropolitan areas of Copenhagen, Oslo, and Helsinki and in the city of Umeå. We have evaluated the emissions for the relevant urban source categories and modelled atmospheric dispersion on regional and urban scales. The emission inventories for RWC were based on local surveys, the amount of wood combusted, combustion technologies and other relevant factors. The accuracy of the predicted concentrations was evaluated based on urban concentration measurements. The predicted annual average concentrations ranged spatially from 4 to 7 µg m−3 (2011), from 6 to 10 µg m−3 (2013), from 4 to more than 13 µg m−3 (2013) and from 9 to more than 13 µg m−3 (2014), in Umeå, Helsinki, Oslo and Copenhagen, respectively. The higher concentrations in Copenhagen were mainly caused by the relatively high regionally and continentally transported background contributions. The annual average fractions of PM2.5 concentrations attributed to RWC within the considered urban regions ranged spatially from 0 % to 15 %, from 0 % to 20 %, from 8 % to 22 % and from 0 % to 60 % in Helsinki, Copenhagen, Umeå and Oslo, respectively. In particular, the contributions of RWC in central Oslo were larger than 40 % as annual averages. In Oslo, wood combustion was used mainly for the heating of larger blocks of flats. In contrast, in Helsinki, RWC was solely used in smaller detached houses. In Copenhagen and Helsinki, the highest fractions occurred outside the city centre in the suburban areas. In Umeå, the highest fractions occurred both in the city centre and its surroundings.
