I analyze optimal auction design in the presence of linear type-dependent negative externalities. I characterize the properties of the optimal mechanism when externalities are “strongly decreasing” and “increasing” in the agent’s valuation and I discuss its implementation with sealed-bid auctions. Interestingly, bidding strategies are not necessarily increasing in valuations, and the optimal mechanism can be implemented by setting a price ceiling instead of a reserve price. 相似文献

In Québec, the 2004 survey Biographies et solidarités familiales (‘biographies and family solidarity in Québec’) was the first quantitative survey to deal with the question of the diverse forms of family solidarity as they have changed over time and in line with modifications in family, work, and public policies. Our purpose here is to present the survey itself along with a certain number of its results. The latter bear, on the one hand, on what we have termed Québec ‘family solidarity spaces’, referring by that to the structural data previous to forms of solidarity as we know them now and, on the other hand, on the changes in the provision of early childhood care over three generations. 相似文献

This article analyses the ways in which community,one of the most important yet ill-defined concepts in SocialSciences, has been appropriated in the discourseof the UK's New Labour government. It argues that the highlystrategic ways in which the term is used leads to associatedmeanings that neglect the intrinsically complex nature of theconcept and risk essentializing group identities, thus adverselyaffecting the most deprived sections of society. 相似文献

This study evaluates attitudes and knowledge of parents regarding gambling behaviors among youths, aged 5 to 17 years. Telephone interviews were conducted among 279 randomly selected parents (32% fathers and 68% mothers) in the Quebec City region. Results indicate that parents overestimate the age of children's first wagers and underestimate the probability that their own child has already gambled. Most parents (86%) believe that the availability of gambling for youths should be reduced and that schools should include prevention programs concerning problem gambling. Results also show that parents fail to associate excessive gambling with poor grades or with alcohol and drug use. Finally, 84% of the parents reported that they would accept buying lottery tickets for their child. These results suggest that prevention programs for excessive gambling among children should include information for parents. 相似文献

In this paper, we analyze an intra-personal game where a decision-maker is summarized by a succession of selves. Selves may
(or may not) have conflicting interests, and earlier selves may have imperfect knowledge of the preferences of future selves.
At date 1, self-1 chooses a menu, at date 2, the preferences of self-2 realize and self-2 chooses an item from the menu. We
show that equilibrium choice is consistent with either a preference for flexibility, a preference for betweenness or a preference
for systematic restriction. Overall, the analysis reconciles the decision–theoretic approach of choice over time with the
game–theoretic multiple-selves approach. 相似文献

School Engagement Trajectories and Their Differential Predictive Relations to Dropout 总被引:4,自引:0,他引:4

Although most theories draw upon the construct of school engagement in their conceptualization of the dropout process, research addressing its hypothesized prospective relation with dropout remains scarce and does not account for the academic and social heterogeneity of students who leave school prematurely. This study explores the reality of different life-course pathways of school engagement and their predictive relations to dropout. Using an accelerated longitudinal design, we used growth mixture modeling to generate seven distinct trajectories of school engagement with 12- to 16-year-old students (N = 13,300). A vast majority of students were classified into three stable trajectories, distinguishing themselves at moderate to very high levels of school engagement. We refer to these as developmentally normative pathways in light of their frequent occurrence and stability. Although regrouping only one-tenth of participants, four other nonnormative (or unexpected pathways) accounted for the vast majority of dropouts. Dropout risk was closely linked with unstable pathways of school engagement. We conclude by debating the delicate investment balance between universal strategies and more selective and differentiated strategies to prevent dropout. We also discuss the need to better understand why, within normative trajectories, some students with high levels of school engagement drop out of school . 相似文献

Hormonal replacement therapy (HRT) helps to prevent osteoporosis. The effect of short-term discontinuation of a long-term HRT on bone mineral density (BMD) in healthy post-menopausal women is unknown. Fifteen women on HRT (HRT users), 17 who never used HRT (non-users) and 8 former HRT users (past-HRT users) were recruited. BMD was measured by DXA. Our results allow to hypothesize that BMD may decline after short-term HRT discontinuation, which would increase the fracture risks. Indeed, our results show that past-HRT users are osteopenic just as non-users. However, these results should be re-examined using a prospective trial and a larger sample size. 相似文献

Le monde étudiant est profondément marqué par la diversité des tra‐jectoires individuelles, qui sont souvent très éloignées d'un déroule‐ment linéaire des études. Les conséquences sur l'âge des étudiants sont majeures, et la condition étudiante ne peut plus être définie comme une expérience strictement juvénile. Or, entre 20 et 30 ans, l'âge engendre des impératifs différentiels sur le plan des conditions et des modes de vie qui ne sont pas toujours compatibles avec la condition étudiante classique. Cette étude des parcours et de la situation financière des étudiants des universités québécoises de langue françhise et anglaise montre comment s'opère la déconnexion entre jeunesse et condition étudiante, et comment cette déconnexion influe sur la différenciation des conditions de vie et de financement des études. Student life is profoundly marked by the diversity of individual trajectories, which are in stark contrast with the linear path traditionally taken by students. The impact on the age of the student population is significant: indeed, student life can no longer be qualified as strictly for the young. Between the ages of 20 and 30 years, different imperatives come into play in terms of living conditions and lifestyle. These imperatives are not always compatible with the conditions of classic student life. This study of the academic paths and the financial situation of Quebec university students shows how the disconnection between student condition and youth occurs and how this disconnection impacts the differentiation of student's living conditions and modes of financing university studies. 相似文献

ABSTRACTIn the past, the behaviours and personalities of mothers have been identified as potential causes of autism. More recently, other etiological hypotheses have been used to explain autism spectrum disorder, suggesting that this specific type of mother-blaming is now uncommon. However, some authors have pointed out that mothers are still being held responsible for their children’s condition and behaviours, as they are now expected to extensively promote their children’s development. The present article explores contemporary forms of mother-blaming experienced by thirteen mothers of children with autism spectrum disorder. The results are discussed in relation to the consequences of mother-blaming, such as social isolation and health related problems. It is hoped that this article will encourage social workers and professionals to understand the mothers’ perspectives and to recognize the importance of supporting them without generating or increasing mother-blaming. 相似文献

We propose a robust rank-based estimation and variable selection in double generalized linear models when the number of parameters diverges with the sample size. The consistency of the variable selection procedure and asymptotic properties of the resulting estimators are established under appropriate selection of tuning parameters. Simulations are performed to assess the finite sample performance of the proposed estimation and variable selection procedure. In the presence of gross outliers, the proposed method is showing that the variable selection method works better. For practical application, a real data application is provided using nutritional epidemiology data, in which we explore the relationship between plasma beta-carotene levels and personal characteristics (e.g. age, gender, fat, etc.) as well as dietary factors (e.g. smoking status, intake of cholesterol, etc.). 相似文献
