Citizenship education has evolved substantially in recent decades, with a rapid proliferation of education forms and approaches. The currently available evaluation studies, however, do not allow us to determine what kind of approach can be considered as a best practice for schools and education systems. In this article, we rely on the results of a 5-year panel study to investigate the long-term effects of various forms of citizenship education. Using the Belgian Political Panel Survey (n = 3,025), a three-wave longitudinal panel survey of 16-, 18- and 21-year-old Belgian late adolescents and young adults, we determine which citizenship education effort (i.e., classroom instruction, being a member of a school council, and an open-classroom climate) has a long-term effect on political trust and political interest. The results suggest that classroom instruction, the presence of an open-classroom climate, and being a member of a school board are positively related to political trust. We also find that classroom instruction and being a member of a school board are significantly associated with higher levels of political interest. We close with some observations on what these findings imply for citizenship education policies. 相似文献

Does the uncertainty associated with post-authoritarian transitions cause political and social polarization? Does ubiquitous social media exacerbate these problems and thus make successful democratic transitions less likely? This article examines these questions in the case of Egypt between the 11 February 2011 fall of President Hosni Mubarak and the 3 July 2013 military coup, which overthrew President Mohamed el-Morsi. The analysis is based on a Twitter dataset including 62 million tweets by 7 million unique users. Using a mix of quantitative and qualitative methods, we demonstrate how clusters of users form and evolve over time, the density of interactions between them, and the flow of particular types of information through the clustered network structure. We show that the Egyptian Twitter public developed into increasingly isolated clusters of the like-minded which shared information unevenly. We argue that the growing distance between these clusters encouraged political conflict and facilitated the spread of fear and hatred, which ultimately undermined the democratic transition and won popular support for the military coup. 相似文献

We analyze the welfare gains from the reform of existinggovernment-induced distortions. Our results provide support forpolicies aimed at eliminating monopoly and other types of economicdistortion. Welfare gains over the status quo exist wheneverderegulation occurs. The threat of deregulation can induce amonopoly or cartel to modify its behavior, so a reform policy canprove beneficial even if reform does not actually occur. Optimalpolicy with commitment in fact allows a monopoly to deterderegulation. The possibility of reregulation does not reverse ourresults; the per period welfare gain from reform remainsundiminished. 相似文献

The authors trace the successive transformations of the large London commercial law firm, which entered the 20th century as a small group of partners, typically from one or more family groups, surrounded by a large group of working class clerks who performed much of the ‘professional work’. After mid-century this firm based on kinship and class hierarchy gave way to a larger firm consisting of non-kin partners selected meritocratically presiding over an increasing band of assistant solicitors and trainees recruited on the basis of their educational credentials and taking part in a promotion-to-partnership tournament. In the last decade of the century, the central institutions and understandings of this meritocratic firm gave way to a constellation of larger, less stable, and increasingly supra-national aggregations, in a setting pervaded by a fascination, both instrumental and narcissistic, with rank and image. 相似文献

Reliability and validity are critical standards of scientific inquiry. This analysis directs attention to problems of reliability in data collection and to problems of validity in measuring two key criminal justice variables: the offense and the sentence. The discussion and empirical analysis indicate that reliability of official information sources in criminal justice cannot be assumed. Furthermore, there is evidence to suggest that the criterion of validity is even more elusive. This elusiveness is demonstrated in the operational definition of criminal offense, an important predictor variable, and in attemps to operationally define the criminal sanction, i.e., the disposition of charges against convicted defendants. These considerations suggest that research in the sentencing area may not be directed to the subject at hand and that research results should be interpreted with “scientific” caution. 相似文献

Analytical records concerning 440 living drivers suspected of driving under the influence of drug (DUID) were collected and examined during a 2 years period ranging from 2002 to 2003 in canton de Vaud, Valais, Jura and Fribourg (Switzerland). This study included 400 men (91%) and 40 women (9%). The average age of the drivers was 28+/-10 years (minimum 16 and maximum 81). One or more psychoactive drugs were found in 89% of blood samples. Half of cases (223 of 440, 50.7%) involved consumption of mixtures (from 2 to 6) of psychoactive drugs. The most commonly detected drugs in whole blood were cannabinoids (59%), ethanol (46%), benzodiazepines (13%), cocaine (13%), amphetamines (9%), opiates (9%) and methadone (7%). Among these 440 cases, 11-carboxy-THC (THCCOOH) was found in 59% (median 25 ng/ml (1-215 ng/ml)), Delta(9)-tetrahydrocannabinol (THC) in 53% (median 3 ng/ml (1-35 ng/ml)), ethanol in 46% (median 1.19 g/kg (0.14-2.95 g/kg)), benzoylecgonine in 13% (median 250 ng/ml (29-2430 ng/ml)), free morphine in 7% (median 10 ng/ml (1-111 ng/ml)), methadone in 7% (median 110 ng/ml (27-850 ng/ml)), 3,4-methylenedioxymethamphetamine (MDMA) in 6% (median 218 ng/ml (10-2480 ng/ml)), nordiazepam in 5% (median 305 ng/ml (30-1560 ng/ml)), free codeine in 5% (median 5 ng/ml (1-13 ng/ml)), midazolam in 5% (median 44 ng/ml (20-250 ng/ml)), cocaine in 5% (median 50 ng/ml (15-560 ng/ml)), amphetamine in 4% (median 54 ng/ml (10-183 ng/ml)), diazepam in 2% (median 200 ng/ml (80-630 ng/ml)) and oxazepam in 2% (median 230 ng/ml (165-3830 ng/ml)). Other drugs, such as lorazepam, zolpidem, mirtazapine, methaqualone, were found in less than 1% of the cases. 相似文献

Players are assumed to rank each other as coalition partners. Two processes of coalition formation are defined and illustrated:BU coalitions are stable in the sense that no member would prefer to be in another coalition, whereas FB coalitions, whose members need not rank each other highest, may not be stable. BU coalitions are bimodally distributed in a random society, with peaks around simple majority and unanimity; the distributions of majorities in the US Supreme Court and in the US House of Representatives follow this pattern. The dynamics of real-life coalition-formation processes are illustrated by two Supreme Court cases.

- Fallback (FB): Players seek coalition partners by descending lower and lower in their preference rankings until some majority coalition, all of whose members consider each other mutually acceptable, forms.
- Build-up (BU): Same descent as FB, except only majorities whose members rank each other highest form coalitions.

Conceptual Analysis and Measurement of Adolescent Autonomy 总被引:6,自引:0,他引:6
The aim of the present study was to examine the concept of adolescent autonomy. A conceptual analysis of different theoretical perspectives has resulted in an integrative model of attitudinal, emotional, and functional autonomy. Attitudinal autonomy refers to the cognitive process of choosing and defining a goal. Emotional autonomy refers to the affective process of feeling confident about one's own choices and goals. Functional autonomy refers to the regulatory process of developing a strategy to achieve these goals. The empirical value of this model was tested by developing a questionnaire assessing adolescent autonomy. Subjects were 400 adolescents between 12 and 18 years old. Confirmatory factor analyses (LISREL 8) provided evidence for the 3 hypothesized dimensions. 相似文献
