This study explores the emergence of a criminal career in adulthood. The main hypothesis tested is that late criminal onset
(at age 21 or later) is influenced by early factors that delay antisocial manifestations. The Cambridge Study in Delinquent
Development (CSDD) was used to examine early determinants of criminal behavior. 400 Inner London males were followed from
ages 8–10 to 48–50, and were classified as follows: 35 late onsetters who were first convicted at age 21 or later, and did
not have high self-reported delinquency at ages 10–14 and 15–18; 129 early onsetters first convicted between ages 10 and 20;
and 236 unconvicted males. Odds ratios and logistic regression analyses revealed that the best predictors of late onset offenders
compared with early onset offenders included nervousness, having few friends at ages 8–10, and not having sexual intercourse
by age 18. The best predictors of late onset offenders compared with nonoffenders included teacher-rated anxiousness at ages
12–14 and high neuroticism at age 16. It is concluded that being nervous and withdrawn protected boys against offending in
adolescence but that these protective effects tended to wear off after age 21. These findings show that adult offending can
be predicted from childhood, and suggest that early intervention might prevent a variety of maladjustment problems and difficulties
in adult life.

Correspondence in value orientation between parents and their offspring may be due to actual transmission processes between
generations, but it may also be due to influences from the general value context in society that are common to parents and
their offspring. This common value context is referred to as Zeitgeist. The present study deals with one family relationship
value (i.e., parents’ and adolescents’ obligations toward the family). Participants were 1,252 immigrant and 726 national
adolescent–parent dyads from 10 Western countries. There were significant relationships between the value placed on family
obligations among parents and offspring, and these were independent of gender. Zeitgeist effects, both intergenerational and
intragenerational, were found. The strength of these Zeitgeist effects depended on the basis for defining Zeitgeist, either
a person’s own ethnic group or the wider community including both nationals and immigrants. For explaining national adolescents’
acceptance of their family obligations, both the ethnic and the national Zeitgeist played a role, whereas in the immigrant
groups only the ethnic Zeitgeist played a significant role. In short, in an immigration context it makes sense to distinguish
the influence of a person’s own ethnic group from the influence of the wider community, including other ethnic groups. Explanations
are suggested and implications are discussed.

从国家法角度看,德意志帝国没有由于德国在第二次世界大战中战败而消亡。作为平等的国际法律主体,联邦德国与民主德国于1973年同时被联合国接纳,获得国际社会的承认。联邦宪法法院认为,在1990年两德统一之前,联邦德国与德意志帝国在国际法上的主体身份是一致的。1990年10月民主德国根据《基本法》第23条加入联邦德国之后,联邦德国成为整个德国在国际社会中的惟一代表。对于德国的法律地位和柏林曾一度拥有的相对特殊的地位,关、英、法、苏四国的行动具有决定性影响。 相似文献

Structured analytic techniques (SATs) are intended to improve intelligence analysis by checking the two canonical sources of error: systematic biases and random noise. Although both goals are achievable, no one knows how close the current generation of SATs comes to achieving either of them. We identify two root problems: (1) SATs treat bipolar biases as unipolar. As a result, we lack metrics for gauging possible over-shooting—and have no way of knowing when SATs that focus on suppressing one bias (e.g., over-confidence) are triggering the opposing bias (e.g., under-confidence); (2) SATs tacitly assume that problem decomposition (e.g., breaking reasoning into rows and columns of matrices corresponding to hypotheses and evidence) is a sound means of reducing noise in assessments. But no one has ever actually tested whether decomposition is adding or subtracting noise from the analytic process—and there are good reasons for suspecting that decomposition will, on balance, degrade the reliability of analytic judgment. The central shortcoming is that SATs have not been subject to sustained scientific of the sort that could reveal when they are helping or harming the cause of delivering accurate assessments of the world to the policy community. 相似文献

So Close,but so Far? The Davies Commission and the Contested Politics of UK Airport Expansion

Aviation expansion and the construction of a third runway at Heathrow airport is firmly back on the political agenda. Yet, the stark fact remains that a growing list of British governments has been unable to engineer a partial or temporary policy settlement in aviation. In exploring the challenges of reaching such a settlement, this article characterises the shifting and contested political and policy contexts of UK aviation. It begins by exploring the ‘wicked issue’ of aviation expansion before foregrounding how the politics of air travel is riven by competing policy frames, fragmented governance and the absence of gatekeepers. It argues that the Davies Commission and its efforts to remove aviation from the domain of partisan politics provided little more than a temporary respite for government. It thus concludes by questioning whether the May government's expansion proposals will succeed this time around, outlining how the contributions in this collection address the themes and issues of this overriding policy puzzle. 相似文献

Since the 1980s the Scottish National Party has presented its political project in progressive terms, but this created a twin dilemma: in order to achieve independence, the SNP needed to win political power, and in order to achieve political power it had to win an election, and orthodoxy dictated that winning elections in Scotland involved a centre‐left platform. But the two have often been in conflict, as is clear as the SNP approaches its tenth anniversary in devolved government and agitates for another referendum. 相似文献
