This article analyses the transition governments of Benin and Togo and shows how they had a profound impact on post-transition governance, regardless of the success or failure of the transition. It argues that the essential elements of polyarchy – competition and inclusion – were present in the transition government in Benin, and patterns along these two dimensions have been mirrored in post-transition events. In Togo, by contrast, only the principle of competition, not inclusion, was established in the transition period and present-day Togolese politics continues this pattern. This analysis sheds new light on politics in both countries and offers greater scope for understanding post-transition politics by viewing transition outcomes in terms of political development.  相似文献

This article describes key programmatic and evaluation elements that guided the implementation of the San Diego County YMCA Kinship Navigator Program. A 3-year demonstration project funded by the Administration on Children Youth and Families designed to build a regional navigator system in collaboration with the local child welfare agency to support kinship caregivers. Kinship caregivers (relatives and non-relatives) play a significant role in the well-being of the children in their care. The findings suggest that successfully implemented kinship navigator models are a viable preventive intervention for addressing the needs of kinship families.  相似文献

This study identified factors that protected (a) adolescent bullies from becoming antisocial young adults, and (b) adolescent victims of bullying from subsequent depression. Data were drawn from the Australian Temperament Project, a population birth cohort study that has followed participants since 1983. Systematic examination of potential risk modifiers (protective factors) was conducted within a regression framework. Low negative reactivity was found to protect bullies from later antisocial outcomes and higher parental monitoring moderated (ameliorated) the risk relation between bullying and antisocial behavior. High social skills and understanding schoolwork protected victims from later depression, but high attachment to peers intensified the risk relation between victimization and later depression. Preventive interventions targeting interpersonal skills and parent and peer relationships may be effective in reducing adverse outcomes of bullying.  相似文献

Each year, a significant number of adolescents become pregnant in the United States, with more than half of these pregnancies resulting in live births. Adolescent parenting is associated with poor outcomes, including increased risk of child maltreatment. Youth “aging out” of the foster care system may be at greater risk of maltreating their children due to their experiences of child maltreatment, a lack of social support, and little preparation for parenthood. This article examines current programs and policies targeting pregnant and parenting youth aging out and presents a research agenda that focuses on pregnancy prevention and positive parenting.  相似文献

Research on the housing choice voucher program and housing mobility interventions shows that even with assistance, it is difficult for poor minority families to relocate to, and remain in, low‐poverty neighborhoods. Scholars suggest that both structural forces and individual preferences help explain these residential patterns. However, less attention is paid to where preferences come from, and how they respond to policies and social structure to shape residential decisionmaking. In this paper, we use data from fieldwork with 110 participants in the Baltimore Mobility Program (BMP), an assisted mobility voucher program, to demonstrate how residential preferences can shift over time as a function of living in higher opportunity neighborhoods. Since 2003, BMP has helped over 2,000 low‐income African American families move from high‐poverty, highly segregated neighborhoods in Baltimore City to low‐poverty, racially mixed neighborhoods throughout the Baltimore region. Along with intensive counseling and unique program administration, these new neighborhood contexts helped many women to shift what we term residential choice frameworks: the criteria that families use to assess housing and neighborhoods. Parents who participated in the mobility program raised their expectations for what neighborhoods, homes, and schools can provide for their children and themselves. Parents report new preferences for the “quiet” of suburban locations, and strong consideration of school quality and neighborhood diversity when thinking about where to live. Our findings suggest that housing policies should employ counseling to ensure relocation to and sustained residence in low‐poverty communities. Our work also underscores how social structure, experience, and policy opportunities influence preferences, and how these preferences, in turn, affect policy outcomes.  相似文献

For many low‐income Medicare beneficiaries, Medicaid provides important supplemental insurance that covers out‐of‐pocket costs and additional benefits. We examine whether Medicaid participation by low‐income adults age 65 and up increased as a result of Medicaid expansions to working‐age adults under the Affordable Care Act (ACA). Previous literature documents so‐called “welcome mat” effects in other populations but has not explicitly studied older persons dually eligible for Medicare and Medicaid. We extend this literature by estimating models of Medicaid participation among persons age 65 and up using American Community Survey data from 2010 to 2017 and state variation in ACA Medicaid expansions. We find that Medicaid expansions to working‐age adults increased Medicaid participation among low‐income older adults by 1.8 percentage points (4.4 percent). We also find evidence of an “on‐ramp” effect; that is, low‐income Medicare beneficiaries residing in expansion states who were young enough to gain coverage under the 2014 ACA Medicaid expansions before aging into Medicare were 4 percentage points (9.5 percent) more likely to have dual Medicaid coverage relative to similar individuals who either turned 65 before the 2014 expansions or resided in non‐expansion states. This on‐ramp effect is an important mechanism behind welcome mat effects among some older adults.  相似文献

Abstract:  This paper focuses on bra damage, specifically damage observed in hook and eye fasteners that are generally located at the backstraps of bras. We describe bra design including the method by which hook and eye fasteners are generally constructed. We assess bra damage in two situations where the damage observed was unexpected given the case scenarios. These were: (i) the complainant of an alleged rape attributed damage to her bra hooks to force during a struggle and (ii) the complainant had earlier manipulated her bra hooks in an incident not related to her complaint. Steriomicroscopy and reconstruction experimentation were necessarily used to assess the bra damage. A systematic approach to damage analysis was employed by the forensic practitioners to correctly identify damage as being a result of mechanical manipulation and therefore as falsified. This paper suggests that more examples of falsified damage should be documented.  相似文献

We examined whether individuals’ ability to detect deception remained stable over time. In two sessions, held one week apart, university students viewed video clips of individuals and attempted to differentiate between the lie-tellers and truth-tellers. Overall, participants had difficulty detecting all types of deception. When viewing children answering yes–no questions about a transgression (Experiments 1 and 5), participants’ performance was highly reliable. However, rating adults who provided truthful or fabricated accounts did not produce a significant alternate forms correlation (Experiment 2). This lack of reliability was not due to the types of deceivers (i.e., children versus adults) or interviews (i.e., closed-ended questions versus extended accounts) (Experiment 3). Finally, the type of deceptive scenario (naturalistic vs. experimentally-manipulated) could not account for differences in reliability (Experiment 4). Theoretical and legal implications are discussed.  相似文献
