Understanding local variability in context and mobilising local participation to define development agendas are widely accepted development strategies. There remain, however, significant challenges to the systematic and effective inclusion of local communities and households. Projeto MAPLAN, a pilot project in Ceará, Brazil, is a joint effort of the public sector and civil society designed to create a process of participatory development planning which integrates local-level contextual variations. In this effort, the use of a Participatory Geographic Information System (PGIS) stimulates the participation of community members in analysing their needs, goals, and priorities. The visualisation of these factors through easily understood maps facilitates communication and contributes to a democratic and transparent planning process, thus permitting the articulation of local priorities with the state-level planning apparatus. MAPLAN represents part of a shifting paradigm for rural development planning in the state and provides the tools for the effective inclusion of citizen voice in development policy.  相似文献

Children experiencing parental incarceration face numerous additional disadvantages, but researchers have often relied on these other co‐occurring factors primarily as controls. In this article, we focus on the intimate links between crime and incarceration, as well as on the broader family context within which parental incarceration often unfolds. Thus, parents’ drug use and criminal behavior that precedes and may follow incarceration periods may be ongoing stressors that directly affect child well‐being. We also use our analyses to foreground mechanisms associated with social learning theories, including observations and communications that increase the child's risk for criminal involvement and other problem outcomes. These related family experiences often channel the child's own developing network ties (peers, romantic partners) that then serve as proximal influences. We explore these processes by drawing on qualitative and quantitative data from a study of the lives of a sample of respondents followed from adolescence to young adulthood, as well as on records searches of parents’ incarceration histories. Through our analyses, we find evidence that 1) some effects attributed to parental incarceration likely connect to unmeasured features of the broader family context, and b) together parental incarceration and the broader climate often constitute a tightly coupled package of family‐related risks linked to intergenerational continuities in criminal behavior and other forms of social disadvantage.  相似文献

Transposition of the great vessels (TGV) is a common congenital heart defect that is difficult to diagnose before birth. Antenatal diagnosis is associated with increased survival. Unusual features such as anomalous pulmonary artery origin may delay cyanosis, decreasing clinical suspicion. A three‐week old female infant who had never been cyanotic presented for forensic autopsy due to onset of unresponsiveness at home. History included risk factors for TGV and signs of heart enlargement that were not recognized during life. Cardiac pathology consultation identified D‐type TGV with additional rare anomalies. TGV may present as sudden unexplained infant death (SUID) for forensic autopsy if variant features prevent development of cyanosis. Cardiac pathology consultation is helpful in clarifying these features.  相似文献

The Public Perceptions of Child Welfare Scale measures how the social environment influences child welfare workers, including their job satisfaction and intent to leave. Psychometric studies have validated the scale for private child welfare workers, but there are no validation studies with public agency staff. This study fills that gap, showing stigma and respect are important constructs that also predict worker intent to leave. This research found an additional construct, blame, which was not present in private worker validation studies. The scale provides an important tool for the field as we continue to build evidence for effective recruitment and retention.  相似文献

The changing nature of the transition to adulthood in western societies, such as the United States, may be extending the length of time parents are engaged in “parenting” activities. However, little is known about different approaches parents take in their interactions with their emerging-adult children. Hence, this study attempted to identify different clusters of parents based on the extent to which they exhibited both extremes of control (psychological control, punishment, verbal hostility, indulgence) and responsiveness (knowledge, warmth, induction, autonomy granting), and to examine how combinations of parenting were related to emerging adult children’s relational and individual outcomes (e.g. parent–child relationship quality, drinking, self-worth, depression). The data were collected from 403 emerging adults (M age = 19.89, SD = 1.78, range = 18–26, 62% female) and at least one of their parents (287 fathers and 317 mothers). Eighty-four percent of participants reported being European American, 6% Asian American, 4% African American, 3% Latino, and 4% reported being of other ethnicities. Data were analyzed using hierarchical cluster analysis, separately for mothers and fathers, and identified three similar clusters of parents which we labeled as uninvolved (low on all aspects of parenting), controlling-indulgent (high on both extremes of control and low on all aspects of responsiveness), and authoritative (high on responsiveness and low on control). A fourth cluster was identified for both mothers and fathers and was labeled as inconsistent for mothers (mothers were above the mean on both extremes of control and on responsiveness) and average for fathers (fathers were at the mean on all eight aspects of parenting). The discussion focuses on how each of these clusters effectively distinguished between child outcomes.  相似文献

It is conventional to speak of voting as “habitual.” But what does this mean? In psychology, habits are cognitive associations between repeated responses and stable features of the performance context. Thus, “turnout habit” is best measured by an index of repeated behavior and a consistent performance setting. Once habit associations form, the response can be cued even in the absence of supporting beliefs and motivations. Therefore, variables that form part of the standard cognitive-based accounts of turnout should be more weakly related to turnout among those with a strong habit. We draw evidence from a large array of ANES surveys to test these hypotheses and find strong support.  相似文献

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities.  相似文献

Research on homicides followed by suicides has relied heavily on small samples and relatively short time spans of data. This study helps to fill this gap by examining 26 years of homicide–suicide data from Cuyahoga County, Ohio, between 1991 and 2016. The main data source for the study is medical examiner files. Analyses of the data indicate the rate of homicide–suicide in Cuyahoga County is consistent with other studies but fluctuates considerably across years studied. The majority of victims are female while perpetrators are overwhelmingly male. Black people are overrepresented as victims and offenders. Use of drugs and/or alcohol leading up to the incident is common among perpetrators. Both the homicides and suicides were overwhelming committed with firearms. When comparing our results to the typology of murder–suicides developed by Marzuk, Tardiff, and Hirsch (JAMA 1992;267:3179), we find amorous jealousy is a significant motivating factor in a many cases, including those involving nonintimate partners. Our findings underscore the importance of widespread use of lethality assessment instruments.  相似文献
