In the public debate over incarceration policy, there is considerable disagreement about what value of individual offending frequency (λ) is appropriate to use in estimating incapacitative effects. This article provides an approach for estimating the mean values of λ for diverse subsets of the total offender population, with particular emphasis on subsets generated by filtering through various stages of the criminal justice system. Sharp differences in offending frequency are displayed between robbery and burglary inmates, across three states, and particularly between resident inmates and free, active offenders. Free offenders average 1 to 3 robberies and 2 to 4 burglaries per year, while resident inmates have λ values 10 to 50 times higher. Differences result from the underlying levels of criminal activity and the sanction Levels that offenders face. A highly heterogeneous distribution of offending frequency in the total population of offenders combines with relatively Low imprisonment levels to lead to substantial selectivity of high-λ offenders among resident inmates and a correspondingly low mean value of λ among those offenders who remain free. These results have important implications for estimating incapacitative effects of an increase in incarceration, since the additional inmates will be drawn from free offenders whose mean λ is at least an order of magnitude Lower than that of the current inmate population. 相似文献

This study examines changes in the rate of offending in a sample of 8,834 males whose official juvenile law-violating careers included 26,650 offense episodes between ages 8 and 17 The rate of offending of active offenders (i.e., lambda) varied substantially as a function of age, increasing monotonically with age. Lambda, however, was not related to the age at first offense. In fact, the average lambda was amazingly constant at each individual age level regardless of the age at which offending began or desisted. Results are discussed in the light of age-crime curves known from other data sets and from the perspective of developmental changes in the rate of offending as youths grow older. 相似文献

To account for variance in great powers responses to threats and the implications for the peacefulness of the international system since the late nineteenth century, this article elucidates a theory which refines and synthesizes economic liberal perspectives and realist balance of power theory. I argue that different patterns and levels of economic interdependence in the great power system generate societal-based economic constraints on, or incentives for, state leaders of status quo powers hoping to mobilize economic resources and political support to oppose perceived threats. This mobilization process influences strongly the preferences of status quo powers, other states beliefs about those preferences, and the interpretation of signals in balance of power politics. In this way, economic ties influence the strategies great powers pursue. Firm balancing policies conducive to peace in the international system are most likely, I then hypothesize, when there are extensive economic ties among status quo powers and few or no such links between them and perceived threatening powers. When economic interdependence is not significant between status quo powers or if status quo powers have strong economic links with threatening powers, weaker balancing postures and conciliatory policies by status quo powers, and aggression by aspiring revisionist powers, are more likely. I then illustrate how these hypotheses explain the development of the Franco-Russian alliance of the 1890s and its effectiveness as a deterrent of Germany up to 1905, British ambivalence toward Germany from 1906 to the First World War, the weakness of British, French, Soviet, and American behavior toward Germany in the 1930s and World War II, and the American and European responses to the Soviet threat, including the NATO alliance, and the "long peace" of the post-1945 era. 相似文献

The application of Lacanian psychoanalytic semiotics to the intersecting categories of criminal justice and mental health
is relatively novel. In this paper the phenomenon of transcarceration or the repeated channeling of disordered defendants
(subjects) through institutional regimes of discipline and coercion is outlined. Attention is directed at the intra-psychic
and intersubjective mechanisms responsible for the structuring of discourse. Lacan's schematization on the constitution of
master narratives through the Discourse of the Master is also delineated. The author concludes by demonstrating how transcarceration
is fundamentally about language and privileged speech patterns which agents of both systems as well as subjects themselves
perpetuate.
