Family courts are seeing an increasing number of separating or divorced families who have a special needs child. These cases present complex challenges for family law professionals charged with crafting parenting plans based on best interests standards. For many of these children, the typical developmentally based custodial arrangements may not be suitable, given the child's specific symptoms and treatment needs. We present a model for understanding how the general and specific needs of these children, as well as the demands on parents, can be assessed and understood in the context of divorce. This includes an analysis of risk and protective factors that inform timeshare and custodial recommendations and determinations. The risk assessment model is then applied to three of the most commonly occurring childhood neurodevelopmental and psychiatric disorders likely to be encountered in family court, namely, attention deficit/hyperactivity disorder, depressive disorders, and autistic spectrum disorders.
    Key Points for the Family Court Community
  • There has been a dramatic rise in the population of children with neurodevelopmental, psychiatric, and medical syndromes whose parents are disputing custody in the family courts.
  • Family law professionals of all disciplines should develop a fundamental knowledge base about the most commonly seen special needs children in family court, such as those with neurodevelopmental conditions like autistic spectrum disorder, attention deficit/hyperactivity disorder, and severe depressive disorders (especially with teenagers), which may involve suicidal or self‐harming behaviors.
  • Commonly recommended parenting plans may be inappropriate for many special needs children, as some function significantly below their chronological age and pose extreme behavioral challenges.
  • A systematic analysis of risk and protective factors should inform timeshare arrangements and determinations with this varied population, including the safety of the child and severity of the disorder, parental commitment and availability to pursue medical, educational, and therapeutic services, the parental attunement and insightful about the problem, and the differential parenting skills of each parent.

This article examines the recoupling mechanism of campaign‐style enforcement and its effects on environmental regulatory compliance. Drawing on the policy implementation literature and institutional theory, the authors develop a conceptual model of campaign‐style enforcement in which both resource mobilization and power redistribution are theorized to address decoupling problems in regulatory compliance. The two‐pathway recoupling mechanism is evidenced by an empirical investigation of the implementation of China's energy conservation and emission reduction policy as part of that country's 11th Five‐Year Plan. Findings suggest that campaign‐style enforcement can effectively improve regulatory compliance when it addresses the efficiency/legitimacy conflict by providing policy incentives and reorganizing a clear hierarchy of political authority. The article concludes with a discussion of the strengths and limitations of campaign‐style enforcement.  相似文献

From the point of view of modes of governance and constellations of interdependence, EU research policy offers ideal conditions for the flexible inclusion of non‐member states: it is based on transgovernmental coordination through policy networks rather than supranational legislation, it follows scientific rather than political imperatives, and cooperation is in the interest of both the EU and of Switzerland. This article analyses the degree to which these factors have allowed for Switzerland's inclusion into the regulatory and organisational aspects of EU research policy, and highlights the limits of such flexible sectoral integration.  相似文献

The role of media in promoting political accountability and citizen participation is a central issue in governance debates. Drawing on research into the interactions between radio station owners, journalists, audiences and public authorities during Somali radio call-in programmes we argue that these programmes do not simply offer a new platform for citizens to challenge those who are governing but that they are also spaces where existing power structures reproduce themselves in new forms. We identify the ways the programmes are structured and the different motivations the audience has for participation. Three types of programmes are identified and their relationships with patronage, politics, and performance are examined. Rather than focusing on normative assumptions about the media as a tool of accountability, the article emphasises the importance of understanding radio programmes in their social and political environment, including the overlapping relationships between on-air and off-air networks.  相似文献

Substance use often begins earlier among American Indians compared to the rest of the United States, a troubling reality that puts Native youth at risk for escalating and problematic use. We need to understand more fully patterns of emergent substance use among young American Indian adolescents, risk factors associated with escalating use trajectories, and protective factors that can be parlayed into robust prevention strategies. We used growth mixture modeling with longitudinal data from middle-school students on a Northern Plains reservation (Wave 1 N = 381, M age at baseline = 12.77, 45.6 % female) to identify subgroups exhibiting different trajectories of cigarette, alcohol, and marijuana use. We explored how both risk (e.g., exposure to stressful events, deviant peers) and protective (e.g., positive parent–child relationships, cultural identity) factors were related to these trajectories. For all substances, most youth showed trajectories characterized by low rates of substance use (nonuser classes), but many also showed patterns characterized by high and/or escalating use. Across substances, exposure to stress, early puberty, and deviant peer relationships were associated with the more problematic patterns, while strong relationships with parents and prosocial peers were associated with nonuser classes. Our measures of emergent cultural identity were generally unrelated to substance use trajectory classes among these young adolescents. The findings point to the importance of early substance use prevention programs for American Indian youth that attenuate the impact of exposure to stressful events, redirect peer relationships, and foster positive parent influences. They also point to the need to explore more fully how cultural influences can be captured.  相似文献

Prior research suggests that youths’ engagement in out-of-school time programs may be a crucial factor linking program participation to positive outcomes during adolescence. Guided by the theoretical concept of flow and by stage-environment fit theory, the present study explored correlates of engagement in youth programs. Engagement was conceptualized as the extent to which youth found the program activities enjoyable, interesting, and challenging. The current study examined how program content, monetary incentives, and youth demographic characteristics were linked to youth engagement among a sample of primarily low-income middle and high school youth attending 30 out-of-school programs (n = 435, 51 % female). Results from multilevel models suggested that program content and staff quality were strongly associated with youth engagement. Youth who reported learning new skills, learning about college, and learning about jobs through activities in the program were more engaged, as were youth who found the staff caring and competent. Results demonstrated that the link between learning content for the future and engagement was stronger for older youth than younger youth. In addition, there was a trend suggesting that providing a monetary incentive was associated negatively with youth engagement. Taken as a whole, these findings have important implications for researchers, practitioners, and policymakers interested in understanding the characteristics of out-of-school time programs that engage older youth.  相似文献

Abstract

A discrete choice experiment was conducted to discover the relative importance of five characteristics of developing countries considered by people when choosing countries to donate money to. The experiment was administered via an online survey involving almost 700 university student participants (potential donors). The most important recipient country characteristic for participants on average is hunger and malnutrition, followed by child mortality, quality of infrastructure, income per capita, and, least importantly, ties to the donor’s home country. A cluster analysis of participants’ individual ‘part worth utilities’ representing the relative importance of the country characteristics reveals they are not strongly correlated with participants’ demographic characteristics.  相似文献

The perpetration of bullying is a significant issue among researchers, policymakers, and the general public. Although researchers have examined the link between bullying and subsequent antisocial behavior, data and methodological limitations have hampered firm conclusions. This study uses longitudinal data from 411 males in the Cambridge Study in Delinquent Development from ages 8 to 56 in order to examine the relationship between adolescent bullying and distinct late middle adulthood trajectories of offending, in which different groups of males follow different offending pathways. Results show that self-reported bullying predicts only certain adult offending trajectories but that the effect becomes insignificant once controls are introduced for childhood risk factors, although this may be due to the small number of the most chronic offenders. Study implications and directions for future research are noted.  相似文献

The article evaluates the concept of ‘developmental’ policies, comparing post-communist Russia and Sub-Saharan African (SSA) states. Asian ‘developmental state’ policies have been identified as developmental because of successful industrial policies and leaders’ ability to implement them. The comparison shows that while these features have been absent in SSA, notably due to the trapping effects of commodity dependence, Russia exhibits an original dualistic model where the negative impact of commodity dependence (such as the creation of rents) is compatible with developmental industrial policies. The evidence presented demonstrates the importance of constraints that stem from both economic and political structures, in turn explaining variations in developmental policy effectiveness.  相似文献
