This paper argues for the importance of adopting a population‐level approach to promote more effective parenting and to reduce the risk of child maltreatment. Family‐based interventions based on social learning principles have been shown to make a useful contribution in the treatment of child maltreatment. However, typically such programmes have been used to treat parents who have already become involved in the child protection system. We argue that the creation of community‐wide support structures to support positive parenting is needed to reduce the prevalence of child maltreatment. Such an approach requires several criteria to be met. These include having knowledge about the prevalence rates for the targeted child outcomes sought, knowledge about the prevalence of various parenting and family risk factors, evidence that changing family risk factors reduces the prevalence of targeted problems, having culturally appropriate, cost‐effective, evidence‐based interventions available and making these widely accessible.

Inequality and happiness: Insights from Latin America   总被引:1,自引:0,他引:1  
Inequality is a contentious topic in economics, and its effect on individual welfare remains an open question. We address this question from the perspective of a novel approach in economics – the study of happiness. In this discussion, we draw from our research on the topic, which is based on new empirical evidence from Latin America. We find several differences from studies conducted in the United States and Europe, especially regarding the role of perceptions of mobility and status. We find that inequality has negative effects on happiness in Latin America, where it seems to be a signal of persistent unfairness. Our research also examines the effects of several variables, including wealth, status, and reference group size, on the link between inequality and happiness, with the presumption that these variables can help us identify the channels through which inequality operates as a signaling mechanism. This article is based on a longer research paper [14], which is under review for publication.  相似文献

The impact of premature birth on associative learning was evaluated using simple delay eyeblink conditioning in which a tone conditional stimulus was paired with an air puff unconditional stimulus. Fourteen preterm (28–31 weeks gestation) and 11 full‐term infants completed at least 3 conditioning sessions, 1 week apart, at 5 months of age (corrected age). Preterm and full‐term groups demonstrated associative learning, as confirmed by comparison with an unpaired control group. Preterm infants, however, exhibited more variability in their learning rates. The majority of full‐term infants and half the preterm infants exhibited rapid acquisition and gradual extinction of conditional responding. A greater proportion of preterm than full‐term infants failed to acquire conditional responding within 2 training sessions. Differences in associative learning rates were not the result of differences in arousal or attentional processes. Diversity in acquisition rates exposed an increased risk for disrupted infant learning due to premature birth.  相似文献

This study aims to identify and describe processes of change enabling achievement of stable housing among homeless individuals. Twelve previously homeless individuals who had maintained stable housing for a period of at least 24 consecutive months provided information through semi-structured interviews on the following topics: (1) the personal experience of homelessness, (2) the process of becoming housed, and (3) the role of significant life relationships. Only the second and third topic areas were included in this discussion. Eight categories were developed and analyzed from the qualitative interviews, including: work/employment difficulties, substance use and/or mental illness, cyclical nature of homelessness, personal motivation, housing-related issues, lessons learned, relationships with family/friends and relationships with service providers. The participants highlighted relationships with family, friends and service providers as central in the processes of achieving stable housing.  相似文献

Urbanization impacts on the structure and function of forested wetlands   总被引:3,自引:0,他引:3  
The exponential increase in population has fueled a significant demographic shift: 60% of the Earth's population will live in urban areas by 2030. While this population growth is significant in its magnitude, the ecological footprint of natural resource consumption and use required to sustain urban populations is even greater. The land use and cover changes accompanying urbanization (increasing human habitation coupled with resource consumption and extensive landscape modification) impacts natural ecosystems at multiple spatial scales. Because they generally occupy lower landscape positions and are linked to other ecosystems through hydrologic connections, the cascading effects of habitat alteration on watershed hydrology and nutrient cycling are particularly detrimental to wetland ecosystems. I reviewed literature relevant to these effects of urbanization on the structure and function of forested wetlands. Hydrologic changes caused by habitat fragmentation generally reduce species richness and abundance of plants, macroinvertebrates, amphibians, and birds with greater numbers of invasives and exotics. Reduction in soil saturation and lowered water tables result in greater nitrogen mineralization and nitrification in urban wetlands with higher probability of NO 3 export from the watershed. Depressional forested wetlands in urban areas can function as important sinks for sediments, nutrients, and metals. As urban ecosystems become the predominant human condition, there is a critical need for data specific to urban forested wetlands in order to better understand the role of these ecosystems on the landscape.  相似文献

The Triple P‐Positive Parenting Programme is described as an example of an evidence‐based universal parenting initiative that provides a tiered continuum of interventions of increasing strength but narrowing reach in an effort to make parenting programmes more accessible to parents. Interventions within the system range from the use of the media and brief messages to intensive family interventions for parents where parenting problems are complicated by multiple additional sources of family adversity. Several issues concerning the role of training and organizational factors that influence the successful uptake and implementation of the programme are discussed.

This article explores the implications of a contemporary relational perspective on the use of self in social work practice. The author is responding to an article by Andrea Reupert, who interviewed social workers and reported they tended to see their concept of self as individualistic, autonomous, and only partially defined by others, even though social work practice focuses on person-in-environment. In this article, the author expands the concept of self and argues that a contemporary view of the therapist’s self is one that is dialogic, contextualized, decentered, and multiple. Additionally, the author suggests that this relational perspective has implications for teaching and supervision. Several clinical vignettes are provided to illustrate the concepts under discussion.  相似文献
