‘So Long as I Take my Mobile’: Mobile Phones,Urban Life and Geographies of Young People's Safety

Mobile phone ownership has spread rapidly among young people in the UK. This article contributes to an expanding body of literature which is examining the consequences of this phenomenon for urban life. Our focus is the impact of mobile phones on young people's geographies, particularly their own and their parents’ fears about their safety in public spaces. Quantitative and qualitative findings are presented from two research projects in Gateshead, north‐east England on crime victimization and leisure injury risk for young people, in which the role of mobile phones in managing and negotiating safety emerged as significant. The article highlights the different ways in which young people and parents are using mobile phones for this purpose, and asks whether they are best viewed as technologies of surveillance or empowerment. We also raise questions about the efficacy of mobile phones in protecting young people from risk and fear, in particular examining the mobile as a new site of victimization. Throughout, we emphasize the social unevenness of the uses and impacts of new technologies, which is often underplayed in research. We conclude with the suggestion that although they offer some empowerment to young people in their use of public spaces and their negotiation of risk, mobile phones appear to be reshaping rather than reducing moral panics about young people's presence there. Au Royaume‐Uni, le téléphone mobile s’est répandu rapidement parmi les jeunes. Cet article s’ajoute aux documents en nombre croissant qui étudient les conséquences de ce phénomène sur la vie urbaine. Il s’attache à l’impact des mobiles sur la géographie des jeunes, notamment sur leurs craintes personnelles et celles de leurs parents quant à leur sécurité dans les espaces publics. Il présente des résultats quantitatifs et qualitatifs provenant de deux projets de recherches à Gateshead (nord‐est de l’Angleterre) sur le risque pour les jeunes d’être victimes d’un acte criminel et de se blesser durant un loisir, cas où les mobiles semblent jouer un rôle important pour gérer et négocier la sécurité. L’article met en lumière les différents modes d’utilisation des mobiles à cette fin, par les jeunes et les parents, en se demandant si ces téléphones sont d’abord considérés comme des technologies de surveillance ou de responsabilisation. Il interroge également l’efficacité des mobiles pour protéger les jeunes contre risques et craintes, notamment en envisageant ces téléphones comme nouveau terrain de victimisation. Dans son ensemble, ce travail souligne l’irrégularité sociale des usages et impacts des nouvelles technologies, souvent minimisée dans la recherche. La conclusion suggère que, même s’ils offrent une certaine responsabilisation aux jeunes dans leur utilisation des espaces publics et leur négociation du risque, les téléphones mobiles semblent remodeler, non réduire, les paniques morales liées à leur présence dans ces lieux.     

Consumer use patterns for fresh and processed vegetable products

Consumer use patterns for 43 fresh and processed vegetables were studied in an effort to explain recent shifts in vegetable consumption practices. Data on the appropriateness of each of the vegetables for 10 different uses were collected and analysed to determine food and food use patterns. Nine vegetable factors and two use factors were extracted. Results indicate that in the majority of cases respondents perceive different forms of the same vegetable to be inappropriate substitutes for each other. Patterns were found which reflect the changes in usage patterns for certain forms of vegetables that have occurred in recent years.     

Consumer Protection in Postwar Canada: Role and Contributions of the Consumers' Association of Canada to the Public Policy Process

This article traces the contribution of the Consumers' Association of Canada (CAC) to the advancement of Canadian consumer protection legislation in the decades after World War II. The theory of the consumerism life cycle shows that the CAC as the spearhead of grassroots consumer activism in Canada was able to address effectively consumer concerns at both the administrative and policymaking levels of government. Analysis of the rise and fall of consumerism in post–WWII Canada from the perspective of the consumerism life cycle also might well have implications for the further development of that theory.

REGIONAL IMPACTS OF AIR QUALITY REGULATION: APPLYING AN ECONOMIC MODEL

The South Coast Air Quality Management District promulgated an Air Quality Management Plan (AQMP) in 1989 so as to attain federal air quality standards for the South Coast Air Basin by the year 2007. Because the AQMP affects all walks of life, its economic impact has become the focal point of debates. This paper examines not only the traditional approach to evaluating the direct cost of a public policy change on the regulated community, but also a systematic approach to assessing direct and indirect impacts of such policy change. This latter approach will enhance the decisionmaking process by allowing one to compare the impacts of various projects in the same context.     

Beliefs Aggregation and Return Predictability

We study return predictability using a model of speculative trading among competitive traders who agree to disagree about the precision of private information. Although traders apply Bayes' Law consistently, returns are predictable. In addition to trading on long-term fundamental value, traders also trade on perceived short-term opportunities arising from foreseen future disagreement, as in a Keynesian beauty contest. Contradicting conventional wisdom, this short-term speculation dampens price fluctuations and generates time-series momentum. Model calibration shows quantitatively realistic patterns of return dynamics. Consistent with empirical evidence, our model predicts more pronounced momentum for stocks with higher trading volume.
