In this article we argue that the precautionary principle, as applied to the regulation of science and technology, cannot be considered in any general manner inconsistent with the norms and methods of scientific knowledge generation and justification. Moreover, it does not necessarily curtail scientific‐technological innovation. Our argument flows from a differentiated view of what precaution in regulation means. We first characterize several of the most relevant interpretations given to the precautionary principle in academic debate and regulatory practice. We then use examples of actual precaution‐based regulation to show that, even though science can have varying functions in different circumstances and frames, all of those interpretations recur to scientific method and knowledge, and tend to imply innovation in methods, products, and processes. In fact, the interplay of regulation and innovation in precautionary policy, at least in the case of the interpretations of precaution that our analysis takes into account, could be understood as a way of reconciling the two fundamental science and technology policy functions of promotion and control. 相似文献

Spritzer DT Rohde LA Benzano DB Laranjeira RR Pinsky I Zaleski M Caetano R Tavares H 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2011,27(4):649-661
The objectives of the study are: (a) to provide the first prevalence estimates of pathological gambling among Brazilian adolescents
using an age-specific instrument in a nationally representative sample; (b) to investigate the extent to which adolescents
participate in gambling activities in a developing country; and (c) to correlate different levels of gambling behavior with
demographic variables. Multistage cluster sampling selected 3,007 individuals over 14 years of age from Brazilian household
population. A total of 661 participants were between 14 and 17 years old. The Lie/Bet Questionnaire and the DSM-IV-MR-J were
used for assessing problem and pathological gambling. 2.8% scored positive on the screening questionnaire, while 1.6% were
classified as problem and pathological gamblers. Factors associated with problem and pathological gambling were male sex,
not currently studying and considering religion as not important. Less than 4 months elapsed between the age of regular gambling
involvement and the first gambling problem. Prevalence rates were quite similar from recent studies which used nationally
representative samples. The association of problem and pathological gambling with male sex, school drop-out and low religiosity
supports the Problem Behavior Theory. The fast progression to problem gambling adds evidence that adolescents may be more
vulnerable to the effects of gambling. 相似文献

In this paper, we present a model of implementation where infeasible allocations are converted into feasible ones through
a process of renegotiation that is represented by a reversion function. We describe the maximal set of Social Choice Correspondences
that can be implemented in Nash Equilibrium in a class of reversion functions that punish agents for infeasibilities. This
is used to study the implementation of the Walrasian Correspondence and several axiomatic solutions to problems of bargaining
and taxation. 相似文献

Automotive sound systems vary widely in terms of functions and way of use between different brands and models what can bring difficulties and lack of consistency to the user. This study aimed to analyze the usability of car stereo commonly found in the market. Four products were analyzed by task analysis and after use reports and the results indicate serious usability issues with respect to the form of operation, organization, clarity and quality of information, visibility and readability, among others. 相似文献

Factors related to the height of the load and the frequency of handling have become a way to predict the acceptable standard weight lifted for workers whose main task is the manual lifting of materials and measuring the conditions is important to determine a maximum weight lifted. This study was conducted to twenty (20) workers between eighteen (18) and forty (40) years old with a minimum six months experience and belonging to the warehouse and packaging area of a dairy products company. Consideration was given to three different heights such as knuckle, shoulder and total height as well as frequencies of 2, 4 and 6 times per minute. Average values for lifted weight were 17.9306 ± 2.37 kg. The conclusions and recommendations included a review of legislation related to Colombian maximum acceptable weight of lifting due to the current law does not match the acceptable weight handled in this research. 相似文献

This paper studies how consumers' reported practices related to food, energy use in housing, daily mobility, and tourism are combined and structured. Social practice theories are the main theoretical framework of this research. Data are drawn from a sensitisation campaign run by the WWF-Belgium and the methods developed to attempt to translate the theoretical focus to practices. Results show that both the low number of ‘green’ practices reported and the multiplicity of combinations of practices indicate a rather important compartmentalisation of ‘green’ practices and seem to refute the hypothesis of vast domino effects in these four different areas. In addition, a wider openness to information on environmentally friendlier practices is associated with a larger number of such practices, which raises questions about the design of such campaigns. Finally, there is no conventionalised way of linking practices and commitments taken by the respondents to reduce their environmental impact. A few policy recommendations are derived for sensitisation campaigns that often assume domino effects between ‘green’ practices, and for tools dealing with personal carbon awareness. 相似文献

Adolescence for the Puerto Rican girl in the United States constitutes a phase of life in which developmental tasks are strained by the demands of her family and exposure to two cultures. This stress renders her adaptive potentials vulnerable to dysfunction. The authors describe the Puerto Rican family, the girl's socialization, the stress of living in dual cultures, and implications for behavioral problems. These factors are integrated to help the practitioner design culturally sensitive interventions.Carl Bryant is an Adjunct Assistant Professor Hunter College School of Social Work and is also in private practice. 相似文献

Anticipating catastrophes through extreme value modelling 总被引:11,自引:0,他引:11

Summary. When catastrophes strike it is easy to be wise after the event. It is also often argued that such catastrophic events are unforeseeable, or at least so implausible as to be negligible for planning purposes. We consider these issues in the context of daily rainfall measurements recorded in Venezuela. Before 1999 simple extreme value techniques were used to assess likely future levels of extreme rainfall, and these gave no particular cause for concern. In December 1999 a daily precipitation event of more than 410 mm, almost three times the magnitude of the previously recorded maximum, caused devastation and an estimated 30000 deaths. We look carefully at the previous history of the process and offer an extreme value analysis of the data—with some methodological novelty—that suggests that the 1999 event was much more plausible than the previous analyses had claimed. Deriving design parameters from the results of such an analysis may have had some mitigating effects on the consequences of the subsequent disaster. The themes of the new analysis are simple: the full exploitation of available data, proper accounting of uncertainty, careful interpretation of asymptotic limit laws and allowance for non-stationarity. The effect on the Venezuelan data analysis is dramatic. The broader implications are equally dramatic; that a naïve use of extreme value techniques is likely to lead to a false sense of security that might have devastating consequences in practice. 相似文献

A future for the E.U., dominated by an ever-increasing population of retired citizens represents a major challenge to social and health policy in European countries. Under Rowe and Kahn’s (Gerontol 37(4):433–440, 1997) perspective on positive aging, this paper is interested in exploring the role of health on citizens’ active participation after retirement and social engagement to life and quality of life. This paper also aims at finding whether Sen’s (Public health, ethics, and equity. Oxford University Press, Oxford, 2004) capability approach or cumulative disadvantage or advantage theory relative to the access to health also verifies in a context of multi-national developed economies. The first part of this study is therefore concerned with generating a health indicator that enables this, whilst controlling for individual heterogeneity in self-rated health responses from 10,859 retired individuals from the SHARE survey. Socioeconomic determinants of health are found not to be critical in determining health in such a developed context whilst cumulative advantage is found relevant for the positive aging of Europeans. Evidence is found that active engagement in activities and quality of life are most certainly a prerogative for the more educated and the healthier retirees, hinting a strategy for European policymakers: cumulative advantage, leveraged by education and health policy, might just be the long-term strategy for contouring an aging and unproductive European population, transforming what could be a ‘burden’ into an asset. 相似文献
