Changes in the family structure can be very disruptive to adolescents who live in those families. This article examines the
impact of the number of family transitions on delinquent and drug-using behavior. Specifically, the effect of family transitions
is hypothesized to be mediated by problems within the family, school, and peer settings. A sample of 646 boys (73%) and girls
(27%) taken from a longitudinal panel study of high-risk adolescents are used to examine these hypotheses. For girls, little
support is found for the direct or the indirect effect of family transitions on delinquent behavior or drug use. For boys,
however, both forms of problem behavior are influenced by family transitions directly and indirectly through changes in, and
problems with, peer associations. The findings suggest that during times of family turmoil, the friendship network of adolescent
male children is also disrupted, leading to an increase in associations with delinquent others and, in turn, an increase in
problematic behaviors.

AbstractAgricultural interventions are thought to have the potential to improve nutrition, but little rigorous evidence is available about programmes that link the two. In this article, we study impacts of an integrated agricultural and nutritional biofortification project, the REU in Mozambique. We first provide evidence on dietary impacts of the programme and then examine impacts of the programme by participation intensity. Using OLS and IV techniques, we find that more intense participation in both project components led to larger impacts. The results therefore have important implications for refining the design of future projects attempting to link agricultural and nutrition interventions. 相似文献

Democracy as political doctrine has its fair share of controversies over the adjudication of rights and the prioritization
of the individual over the community. These debates have largely derived from its western genesis. The current stage of global
development has however supplied many non-western perspectives on democracy which suggest that any consensus over an identifiable
body of democratic thought is likely to witness more sub-diversity than ever before. This article argues that contemporary
Asian thinkers on the philosophy of government have a valuable contribution to make to democratic discourse notwithstanding
the clichés of the Asian Values debate of the 1990s. By performing a sampled reading of José Rizal, Sukarno and Lee Kuan Yew
on their diverse interpretations of guided democracy in a nationalistic context, it will be shown that these three modern
Southeast Asian political thinkers would offer some tentative Asian insights on the democracy of dignity and of responsibility.

This article draws on health sector reform in Honduras to examine the mechanisms through which governance reforms shape the behavior of street-level bureaucrats. It combines insights from behavioral public administration with original data from lab-in-the-field workshops conducted with more than 200 bureaucrats to assess the relationship between decentralization and motivation. Findings show strong evidence that motivation, measured as self-sacrifice, is higher among bureaucrats in decentralized municipalities compared with bureaucrats in comparable centrally administered municipalities. Increased motivation is most pronounced in decentralized systems led by nongovernmental organizations compared with those led by municipal governments or associations. Additionally, the evidence suggests that higher motivation is related to changes in the composition of staff rather than socialization or changes among existing staff. Overall, this research helps move beyond indiscriminate calls for decentralization by highlighting the interplay between reform design and bureaucratic behavior, as well as the limitations of governance reforms in motivating more experienced bureaucrats. 相似文献

Since the 1980s identities have re-emerged as a powerful factor shaping support for specific public policies, often doing so at the expense of prioritising the interests of future generations. Outside the United States a major causal factor has been the declining ability of many political parties to mobilise support for themselves and their policies. Consequently, considerations derived from the past can be at the expense of future citizens. This article analyses two major policies separated by a century—Prohibition in the US and Brexit. With both, the enacted policies featured limited previous public discussion about their likely consequences. Moreover, in both cases it was a ‘hard’ version that would be enacted, even though some supporters had favoured more moderate policy options. While not all policies driven by support from particular identities harm future generations, some do. This results from politicians in public utterances previously being insufficiently focussed in detail on the policy’s consequences. 相似文献

The concentrations of zolpidem and zopiclone were determined in peripheral blood samples in two forensic materials collected over a 10-year period (2001-2010). The z-hypnotics were determined in venous blood from living subjects (impaired drivers) and in femoral blood from deceased persons (forensic autopsies), with the latter classified as intoxication or other causes of death. The z-hypnotics were determined in blood by capillary column gas chromatography (GC) with a nitrogen-phosphorous (N-P) detector after solvent extraction with n-butyl acetate. The analytical limit of quantitation (LOQ) was 0.02mg/L for zopiclone and 0.05mg/L for zolpidem and these have remained unchanged throughout the study. When death was attributed to drug intoxication (N=918), the median concentration of zopiclone in blood was 0.20mg/L compared with 0.06mg/L for other causes of death (N=1215) and 0.07mg/L in traffic offenders (N=691) (p<0.001). Likewise, a higher median concentration (0.30mg/L) was found in intoxication deaths involving zolpidem (N=357) compared with 0.13mg/L for other causes of death (N=397) or 0.19mg/L in impaired drivers (N=837) (p<0.001). Median concentration in blood of both z-hypnotics were appreciably higher in intoxication deaths when no other substances were identified; 0 70mg/L (N=12) for zopiclone and 1.35mg/L (N=12) for zolpidem. The median concentrations of z-hypnotics in blood decreased as the number of co-ingested substances increased for intoxication deaths but not other causes of death. The most prevalent co-ingested substances were ethanol in autopsy cases and diazepam in the motorists. This large compilation of forensic cases should prove useful when toxicologists are required to interpret concentrations of z-hypnotics in blood samples in relation to cause of death. 相似文献

The Patient Protection and Affordable Care Act (ACA) requires that adults up to age twenty-six be permitted to enroll as dependents on their parents' health plans. This article examines the experiences of states that enacted dependent expansion laws. Drawing on public information from thirty-one enacting states and case studies of four diverse reform states, it derives lessons that are pertinent to the implementation of this ACA provision. Dependent coverage laws vary across the states, but most impose residency, marital status, and other restrictions. The federal Employee Retirement Income Security Act further limits the reach of state laws. Eligibility for expanded coverage under the ACA is much broader. Rules in some states requiring or allowing separate premiums for adult dependents may also discourage enrollment compared with rules in other states (and the ACA), where these costs must be factored into family premiums. Business opposition in some states led to more restrictive regulations, especially for how premiums are charged, which in turn raised greater implementation challenges. Case study states did not report substantial young adult dependent coverage take-up, but early enrollment experience under ACA appears to be more positive. Long-term questions remain about the implications of this policy for risk pooling and the distribution of premium costs. 相似文献
