This article examines the well-documented relationship between early initiation or onset of criminal behavior and a heightened
risk of involvement in offending. Previous research examining this question conducted by Nagin and Farrington (Criminology
30:235–260, 1992a; Criminology 30:501–523, 1992b) used data from the Cambridge Study in Delinquent Development and found that: (1) onset age was correlated with offending
involvement; and (2) the correlation could be explained by stable individual differences in the propensity to offend rather
than a causal effect of early onset age. In this study, similar analytic methods are applied to data from the Second Philadelphia
Birth Cohort. This data set consists of all 13,160 males born in Philadelphia in 1958 who resided in the city continuously
from ages 10 to 18, slightly more than half of whom were non-white. Information from each of the youths was collected from
schools, juvenile justice agencies, other official sources and surveys. In a model that mimics previous analyses, we initially
found that an early age of onset is associated with greater subsequent involvement in delinquent behavior. When unobserved
criminal propensity was controlled, however, we found that a late rather than an early onset of delinquency was related to
future offending. In finding a state dependent effect for age of onset, our findings are contrary to propensity theory in
criminology. In finding that it is late rather early onset which puts youth at risk for future offending, our findings are
contrary to developmental/life course theory. Our results are more compatible with traditional criminological theory that
is friendly to state dependence processes, though they too have not to date articulated why a late onsetting of offending
might be particularly criminogenic.

Growth curve analyses were used to investigate parents’ and peers’ influence on adolescents’ choice to abstain from antisocial
behavior in a community-based sample of 416 early adolescents living in the Southeastern United States. Participants were
primarily European American (91%) and 51% were girls. Both parents and peers were important influences on the choice to abstain
from antisocial behavior. Over the four-year period adolescents relied increasingly on parents as influences and relied less
on peers as influences to deter antisocial behavior. Significant gender differences emerged and suggested that female adolescents
relied more on social influences than did male adolescents but that as time progressed male adolescents increased the rate
at which they relied on peers. Higher family income was associated with choosing peers as a social influence at wave 1, but
no other significant income associations were found. Understanding influences on adolescents’ abstinence choices is important
for preventing antisocial behavior.

Scraping by: Income and Program Participation After the Loss of Extended Unemployment Benefits 下载免费PDF全文
Many Unemployment Insurance (UI) recipients do not find new jobs before exhausting their benefits, even when benefits are extended during recessions. Using Survey of Income and Program Participation (SIPP) panel data covering the 2001 and 2007 to 2009 recessions and their aftermaths, we identify individuals whose jobless spells outlasted their UI benefits (exhaustees) and examine household income, program participation, and health‐related outcomes during the six months following UI exhaustion. For the average exhaustee, the loss of UI benefits is only slightly offset by increased participation in other safety net programs (e.g., food stamps), and family poverty rates rise substantially. Self‐reported disability also rises following UI exhaustion. These patterns do not vary dramatically across household demographic groups, broad income level prior to job loss, or the two business cycles. The results highlight the unique, important role of UI in the U.S. social safety net. 相似文献

This paper analyses ASEAN's prominence in regional order negotiation and management in Southeast Asia and the Asia-pacific through the lens of social role negotiation. It argues that ASEAN has negotiated legitimate social roles as the ‘primary manager’ in Southeast Asia and the ‘regional conductor’ of the Asia-Pacific order. It develops an English School-inspired role negotiation framework and applies it to three periods: 1954–1975 when ASEAN's ‘primary manager’ role emerged from negotiations with the USA; 1978–1991 when ASEAN's role was strengthened through negotiations with China during the Cambodian conflict; and 1991-present when ASEAN created and expanded the ‘regional conductor’ role. Negotiations during the Cold War established a division of labour where great powers provided security public goods but the great power function of diplomatic leadership was transferred to ASEAN. ASEAN's diplomatic leadership in Southeast Asia provided a foundation for creating its ‘regional conductor’ role after the Cold War. ASEAN's ability to sustain its roles depends on maintaining role bargains acceptable to the great powers, an increasingly difficult task due to great power rivalry in the South China Sea. 相似文献

Although there has been considerable enthusiasm for public service motivation (PSM) research in recent years, two of PSM's fundamental assumptions have been relatively untested: its impacts on job choice and on job performance. Using panel data from two different studies, we offer stronger observational tests of these core assumptions. The findings provide mixed evidence. When testing PSM's effect on employment choice, we find that PSM measured during a law student's first year predicts the sector in which they are employed after graduation three years later. In a separate study investigating PSM's effect on job performance, we find that government employee PSM does not predict employee absenteeism or supervisor assessments of their in-role and extra-role performance. Our findings support recent calls for a more nuanced theory and analyses of PSM to help better understand its implications for recruiting, retaining, and motivating the workforce used to provide public goods and services. 相似文献
