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

Potency of delta 9-THC and other cannabinoids in cannabis in England in 2005: implications for psychoactivity and pharmacology 总被引:1,自引:0,他引:1
Gas chromatography was used to study the cannabinoid content ("potency") of illicit cannabis seized by police in England in 2004/5. Of the four hundred and fifty two samples, indoor-grown unpollinated female cannabis ("sinsemilla") was the most frequent form, followed by resin (hashish) and imported outdoor-grown herbal cannabis (marijuana). The content of the psychoactive cannabinoid delta 9-tetrahydrocannabinol (THC) varied widely. The median THC content of herbal cannabis and resin was 2.1% and 3.5%, respectively. The median 13.9% THC content of sinsemilla was significantly higher than that recorded in the UK in 1996/8. In sinsemilla and imported herbal cannabis, the content of the antipsychotic cannabinoid cannabidiol (CBD) was extremely low. In resin, however, the average CBD content exceeded that of THC, and the relative proportions of the two cannabinoids varied widely between samples. The increases in average THC content and relative popularity of sinsemilla cannabis, combined with the absence of the anti-psychotic cannabinoid CBD, suggest that the current trends in cannabis use pose an increasing risk to those users susceptible to the harmful psychological effects associated with high doses of THC. 相似文献

ABSTRACTSince 2011, Myanmar has undertaken a series of domestic and foreign policy reforms, including democratisation and peacebuilding, before and after the watershed November 2015 elections in the country. These reform processes have called into question whether China, which has been Myanmar's dominant great power neighbour throughout the previous era of military government in the country formerly known as Burma, would find its strategic position eroding as Myanmar further opens to the international community. However, the concept of China ‘losing’ diplomatic ground to other actors, including the West, in Myanmar implies a zero-sum game that does not adequately address Beijing's still-formidable geostrategic presence vis-à-vis its southern neighbour. China has now started to implement a more multi-faceted, ‘resilience network’-building approach to maintaining its special status in Myanmar's foreign policy, a situation which will persist as Myanmar continues its uncertain path towards further reform. 相似文献

Can Incarcerated Felons Be (Re)integrated into the Political System? Results from a Field Experiment 下载免费PDF全文

How does America's high rate of incarceration shape political participation? Few studies have examined the direct effects of incarceration on patterns of political engagement. Answering this question is particularly relevant for the 93% of formerly incarcerated individuals who are eligible to vote. Drawing on new administrative data from Connecticut, we present evidence from a field experiment showing that a simple informational outreach campaign to released felons can recover a large proportion of the reduction in participation observed following incarceration. The treatment effect estimates imply that efforts to reintegrate released felons into the political process can substantially reduce the participatory consequences of incarceration. 相似文献

How Aspiration to Office Conditions the Impact of Government Participation on Party Platform Change 下载免费PDF全文
Gijs Schumacher Marc van de Wardt Barbara Vis Michael Baggesen Klitgaard 《American journal of political science》2015,59(4):1040-1054
Considerable ambiguity exists regarding the effect of government/opposition status on party platform change. Existing theories predict that (1) it has no effect, (2) opposition parties change more, (3) opposition parties change more after several spells in opposition, and (4) parties’ responses vary because of different goal orientations. We propose that a party's aspiration to office, measured by its historical success or failure in entering office, determines a party's reaction to being in opposition or government. We hypothesize that, because of loss aversion, parties with low office aspiration change more when they are in government than when they are in opposition. Conversely, parties with high office aspiration change more as opposition party than as government party. We find evidence for these hypotheses through a pooled time‐series cross‐sectional analysis of 1,686 platform changes in 21 democracies, using the Comparative Manifesto Data and an innovative measure of party platform change. 相似文献

Konrad N Daigle MS Daniel AE Dear GE Frottier P Hayes LM Kerkhof A Liebling A Sarchiapone M;International Association for Suicide Prevention Task Force on Suicide in Prisons 《危机》2007,28(3):113-121
In 2000 the Department of Mental Health of the World Health Organization (WHO) published a guide named Preventing Suicide. A Resource for Prison Officers as part of the WHO worldwide initiative for the prevention of suicide. In 2007 there are new epidemiological data on prison suicide, a more detailed discussion of risk factors accounting for the generally higher rate of suicide in correctional settings in comparison to the general population, and several strategies for developing screening instruments. As a first step, this paper presents an update of the WHO guide by the Task Force on Suicide in Prisons, created by the International Association for Suicide Prevention. A second paper, by the same Task Force, will present some international comparisons of suicide prevention services in correctional facilities. 相似文献
