Consistent with the view that adolescent relationships are established in the context of important characteristics of their social networks, we examined the effects of adolescents’ experiences of parenting (psychological control and positive monitoring) and of peer aggression and victimization, on their self reports of dating victimization and aggression. We also examined the effects of individual differences in emotional and behavioral problems. We used questionnaire data from a population-based sample of youth 12–18 years old who were in dating relationships (n = 149). Parental monitoring emerged as a protective factor in reducing both dating victimization and relational aggression. Our findings also point to a significant transfer of aggression in peer relationships to relational aggression in dating relationships.

Adolescent bullying is a common problem in schools across America. The consequences of bullying are significant, and can include severe psychological trauma and suicide. A better understanding of the mechanisms that link bullying and suicidal ideation is needed in order to develop effective prevention and intervention initiatives. Meaning in life is a potential mechanism that has not been studied in this context. It was hypothesized that meaning in life could serve as both a mediator and a moderator of the relationship between bullying victimization and suicidal ideation. As a mediator, meaning in life is considered to explain why bullying victimization leads to suicidal ideation. As a moderator, meaning in life is considered to buffer the ill effect of bullying victimization on suicidal ideation. Data collected from an ethnically diverse sample of 2,936 (50 % female), 6th–12th grade students from one urban school district in the Northeastern US were used to examine the hypotheses. The model for girls was consistent with mediation (i.e., meaning in life may explain how victimization leads to suicidal ideation). The model for boys was consistent with moderation (i.e., the ill effect of victimization on suicidal ideation was attenuated as meaning in life increased). Implications for prevention are discussed.  相似文献

This paper provides a selective survey of food regimes and food regime analysis since the seminal article by Harriet Friedmann and Philip McMichael in 1989, and further traced through their subsequent (individual) work. It identifies eight key elements or dimensions of food regime analysis, namely the international state system; international divisions of labour and patterns of trade; the ‘rules’ and discursive (ideological) legitimations of different food regimes; relations between agriculture and industry, including technical and environmental change in farming; dominant forms of capital and their modalities of accumulation; social forces (other than capitals and states); the tensions and contradictions of specific food regimes; and transitions between food regimes. These are used to summarise three food regimes in the history of world capitalism to date: a first regime from 1870 to 1914, a second regime from 1945 to 1973, and a third corporate food regime from the 1980s proposed by McMichael within the period of neoliberal globalisation. Questions of theory, method and evidence are noted in the course of the exposition and pulled together in a final section which criticises the ‘peasant turn’ of the ‘corporate food regime’ and the analytical and empirical weaknesses associated with it.  相似文献

In 2008, the National Aeronautics and Space Administration (NASA) celebrated its fiftieth anniversary, and has been embarked on a mission to put astronauts on the moon, possibly by 2020. Is this goal “back to the future”? Or is it “the way forward” as a prelude to a mission to Mars? An advisory panel to President Obama has recommended alternatives to the moon as routes to Mars. At the time of writing, Obama has yet to decide. Of course, NASA has already arrived on Mars with robots, a tribute to the agency's remarkable technical prowess. However, the ultimate challenge would be to send men and women to Mars. Why? That, of course, is the big question. The answer lies in the human heart rather than in the rational mind. NASA's exploration of this unknown frontier has more in common with the expeditions of Columbus and Magellan than the missions of most other federal agencies. Any list of discretionary expenditures would prioritize space exploration as an extreme example of an unnecessary luxury that can be postponed. So why should NASA continue to explore space? That question takes on an acute meaning during a time of intense domestic economic and foreign policy challenges. But imagine: what would be lost to America if NASA did not exist?  相似文献

Citizens’ expectations about what government is capable of doing and what policies government officials intend to pursue can influence their decisions. After a disaster, for instance, expectations of government’s intent and capacity to assist in the rebuilding process will influence the rebuilding strategies that affected citizens adopt. This article develops a typology that categorizes citizens’ expectations of government response to disaster. We then deploy this typology to identify expectation patterns among residents and other private actors in New Orleans’ Ninth Ward communities who have returned following Katrina and explain how these expectations shape their preferred rebuilding strategy.  相似文献

This article seeks to improve our understanding of policy institutions and cooperation by adapting Long's (1958) analysis of the ecology of games to the context of collaborative land use and transportation planning in California. The traditional institutional rational choice analysis argues that collaborative institutions reduce the transaction costs of cooperation among multiple policy actors. The ecology of games framework extends IRC by emphasizing the consequences of multiple institutions and identifies several reasons why collaborative institutions may actually reduce the amount of cooperation in existing policy venues. Analyses of survey data from policy actors in five California regions demonstrate that higher levels of cooperation in collaborative institutions are associated with lower levels of cooperation in other land‐use and transportation planning institutions.  相似文献

The long‐term budget prospects of the United States are grim. Projected spending greatly exceeds projected revenue over the next few decades. Projected growth of health care spending accounts for more than all of the anticipated gap. Without action to narrow the gap, accumulating deficits will drive up the ratio of debt to GDP. Interest payments will rise correspondingly. At some point, domestic and foreign holders of U.S. debt will come to doubt the capacity of the government to service this debt. At that point, they will demand sharply higher interest rates. The combination of increasing debt and rising interest rates will cause debt service costs to explode. What follows would be some combination of collapsing investment, declining production, debt default, and inflation—in brief, a calamitous mess. That such a mess will occur is certain if budget deficits as large as those currently anticipated are realized. Precisely when is impossible to forecast accurately.  相似文献

Most of the policy discussion on the effects of educational vouchers has been premised on theoretical or ideological positions rather than evidence. This article analyzes a substantial body of recent empirical evidence on achievement differences between public and private schools; on who chooses and its probable impact on educational equity; and on the comparative costs of public and private schools and an overall voucher system. The findings indicate that: (1) results among numerous studies suggest no difference or only a slight advantage for private schools over public schools in student achievement for a given student, but evidence of substantially higher rates of graduation, college attendance, and college graduation for Catholic high school students; (2) evidence is consistent that educational choice leads to greater socioeconomic (SES) and racial segregation of students; and (3) evidence does not support the contention that costs of private schools are considerably lower than those of public schools, but the costs of an overall voucher infrastructure appear to exceed those of the present system.  相似文献
