Being politically interested is one of the most important norms from a democratic perspective, as it is a crucial antecedent for voting, political knowledge, civic and political participation, and attentiveness to political information. However, only limited research has focused on the relationship between media use and political interest, despite the notion that modern politics is mediated politics. Even more important is the fact that the causal relationship between media use and political interest still has not been firmly established. Against this background, the purpose of this study is to investigate the causal relationship between news media use and political interest. The results show that there are indeed causal and reciprocal relationships between political interest and attention to political news, and between political interest and exposure to some, but not all, news media. Overall these results lend stronger support to the perspective of media mobilisation theories than media malaise theories.  相似文献

Oral fluid is becoming increasingly useful for the detection of drugs, since it is a non-invasive specimen to collect and, because collection is directly observed, it is difficult to adulterate. A point-of-collection (POCT) oral fluid drug analysis kit has been developed for use in many drug testing situations. This paper summarizes the results of field evaluations of the ORALscreen System for screening of drugs in oral fluid. The ORALscreen System consists of an oral fluid collection device and a test device containing a lateral flow membrane immunoassay system. Paired samples (oral fluid and urine) were collected from drug users and the results from the ORALscreen POCT system were compared to urine screening results conducted in a licensed laboratory. The results demonstrate that the ORALscreen System has excellent percent agreement with the laboratory-based urine screening test results for the detection of cocaine and opiates through 2.5-3 days following drug use, respectively. Tetrahydrocannabinol (THC) was detected by ORALscreen on the day of use and 1 day after use. Good correlation between urine and oral fluid screening results was observed for the methamphetamine positive samples; however, the number of days following drug use was not determined.  相似文献

This study used hierarchical linear modeling to compare longitudinal patterns of adolescent religious service attendance and club attendance, and to contrast the longitudinal relations between adolescent adjustment and religious service versus club attendance. Participants included 1050 students (47% girls) encompassing a school district in Canada, who completed the survey first in grade nine and again in grades 11 and 12. Results demonstrated that patterns of religious service attendance over time were quite different from other clubs. Religious attendance was uniquely associated with several indicators of positive as well as negative adjustment. Club involvement, conversely, was only associated with positive adjustment––particularly for individuals who reported sustained involvement over time. Findings suggest that religious services may provide some unique experiences––both positive and negative––over and above what may be provided in other clubs, and that sustained, rather than sporadic participation in clubs, may be especially important for adolescent adjustment.

This longitudinal study tested the influence of involvement and selection hypotheses for the association between religious versus non-religious activity involvement and two salient indicators of adolescent psychosocial adjustment (substance use and academic achievement). Participants included 3,993 Canadian adolescents (49.4% girls) who were surveyed each year from grades 9–12. More frequent religious attendance (but not non-religious club involvement) in one grade predicted lower levels of substance use in the next grade. Higher levels of non-religious club involvement (but not religious service attendance) in one grade predicted higher academic achievement in the next grade, and higher academic achievement in one grade predicted more frequent non-religious club involvement in the next grade. The effects were robust, as they were invariant across grade and significant after controlling for individual, peer, and family characteristics. Most importantly, these results suggest that religious activities are not just another club, but, rather, that different developmental assets may be fostered in religious as compared to non-religious activities.  相似文献

Our paper analyzes the merits of four alternatives for providing governmental support to charity—the existing tax write-off, a tax credit, a sliding matching grant, and a percentage contribution bonus. After searching for an appropriate budget mechanism (a five-year fixed-sum authorization and appropriation), we apply a wide-ranging set of criteria—equity, legitimacy, efficiency, reciprocity, controllability, etc.—to each of the four alternatives. In brief, the existing tax write-off is grossly inequitable among donors, poorly controlled by government, and is part of a tax system increasingly viewed as illegitimate by citizens. The advantages of the write-off are that it produces predictable amounts of income at low administrative cost without overtly raising questions of constitutionality. Its disadvantages would be mitigated by a tax credit in proportion to the amounts contributed by taxpayers. But the credit does not reach people who do not file returns and may significantly decrease income to charitable agencies. The sliding matching grant (under which the government pays to charity in proportion as the individual gives of his income) provides a particular form of equity for taxpayers but is deficient in other respects. The contribution bonus—a percentage of each dollar contributed paid to charity by government—is wholly equitable, includes all givers, sustains reciprocity with recipients, is controllable by government, and is legitimate in treating expenditures as expenditures and not as tax dodges. It also raises the possibility of increasing the government's contribution. The defects of the bonus are higher administrative costs and potential doubt about constitutionality. We conclude in favor of a percentage contribution bonus set high enough to provide marginally more income for charity and reduce financial uncertainties during the transition. Appraisal of political feasibility suggests that supporters of charity are likely to be worse off unless they come up with a more defensible approach, such as the contribution bonus. To help resolve doubts, we suggest adding on a small percentage contribution bonus to the present tax write-off for three years so as to test constitutionality and assess more precisely administrative costs. While there is no one proposal that will make everyone better off, the contribution bonus is far superior on most criteria to the alternatives.The paper was written for The Commission on Private Philanthropy and Public Needs. For their criticisms and constructive comments, including those with which we disagreed, we express our appreciation to Professors John McNulty and Lawrence Stone, Law School, and Professors Arnold Meltsner and William Niskanen, Graduate School of Public Policy, all of the University of California (Berkeley).  相似文献

Because states have primary responsibility for the implementation of public health insurance programs, states need timely, good quality data to evaluate programs, monitor trends in the number and characteristics of the uninsured, and better understand the dynamics of health insurance coverage. This article provides a synthesis of the data sources available to states for monitoring rates of health insurance coverage. Information was collected through a comprehensive review of state and national health surveys and in-depth interviews with state analysts in all fifty states. Our findings suggest that national surveys do not meet states' needs for data, and in response, states have initiated their own household surveys. We provide information on thirty-six household surveys that are used to estimate state levels of health insurance coverage. We recommend that national and state efforts be better coordinated to facilitate efficient use of resources to achieve good state-level date.  相似文献
