This paper considers the existence and use of disaster risk management laws across the Commonwealth. It commences by considering approaches to risk management and disaster response. It reviews international and regional disaster law, policy and tools. The paper examines national disaster risk management laws through the lens of a typology of laws, based on the complexity and scope of the disaster risk reduction and response system. It makes recommendations for Commonwealth countries relating to review of disaster laws, implementation of international frameworks, and the inclusion of disaster risk reduction, recovery, climate change, quality standards and the prevention of sexual and gender-based violence in disaster laws.  相似文献

Interviews were conducted with parents of 136 female and 45 male adolescents categorized into risk groups for the later development of an eating disorder. The family and school concomitants of risk status in females were demonstrated to be different from that in males. Risk group female adolescents rated family cohesion, parent-adolescent communication processes, and overall family satisfaction more negatively than the comparison group. Mothers of moderate risk group females reported lower family cohesion than the comparison group; there were no group differences for adolescent females in fathers' ratings of family measures. However, no group differences were found on any of the family measures between male risk and comparison males. For both females and males, there were no significant group differences in family history of eating and mood disorders, or alcohol dependence. Teacher ratings indicated relatively greater internalizing tendencies in the high-risk female group.This investigation was supported by NICHD Grant Number 1R01-HD24700 awarded to Gloria R.

Bacterial species with high DNA sequence similarity to pathogens could affect the specificity of assays designed to detect biological threat agents in environmental samples. The natural presence of four pathogenic bacteria, Bacillus anthracis, Clostridium perfringens, Francisella tularensis, and Yersinia pestis and their closely related species, was determined for a large collection of soil and aerosol samples. Polymerase chain reaction (PCR) and gene sequencing were used using group-specific 16S rRNA primers to identify pathogens and related species, and pathogen-specific virulence genes. Close relatives of B. anthracis (B. cereus group species) were detected in 37% of the soils and 25% of the aerosol samples. The B. anthracis protective antigen (pag) gene or a close homolog was detected in 16 of these samples. For the other three pathogen groups, the frequency of detection was much lower, and none of the samples were positive with both the phylogenetic and virulence gene primer sets.  相似文献

This study examined quality and afterschool program designs with a focus on conditions of persistent low quality. Using an action science case study method, data from a quality-improvement project were examined to explore circumstances and reasons for low quality. Four identified program designs varied by emphasis on academics, school alignment, physical space, resources, and grouping strategies, as well as by the operationalization of youth choice. These program design features were found to be dynamically interrelated and key elements of structural quality yet were not found to be targets of state, funder, or agency quality improvement interventions guided by the current broad theory of change for quality initiatives. Structural quality, conceptualized as dynamic and interdependent, may be a prerequisite condition for self-directed quality improvement or a focus of targeted quality interventions.  相似文献

This experiment drew upon theoretical perspectives on group and system justification to examine whether exposure to media coverage arguing that racism was responsible for the ineffective Hurricane Katrina disaster response affected White and Black Americans’ intergroup attitudes. Consistent with a system justification perspective, Whites exposed to video clips arguing that the hurricane Katrina disaster response was due to racism displayed greater racial ingroup attachment and ingroup love compared to Whites exposed to videos conveying that the government’s incompetence was to blame for the disaster response. In contrast, Blacks displayed strong levels of ingroup attachment and ingroup love across both video conditions. This research highlights how insights from social psychology are valuable in understanding psychological responses to social justice-related events, such as the tragic response to hurricane Katrina.

Abstract

We argue that the proximate reason the United States overuses prisons is that for local prosecutors and judges, sending offenders to prison is “free”; the state pays. By completely subsidizing prison use, states incentivize local overuse of prisons. State prisons in the United States are common pool resources, so options to managing common pool resources used in fisheries and environmental protection may have applications to corrections. We propose, for this purpose, seven options: six involve pricing systems and each having several variants. Each approach, in its own way, puts a price on justice. We also outline other changes in correctional and sentencing practices policy makers need to make to implement these approaches. We anticipate potential consequences, good and bad, of incentivizing justice. Finally, we fully expect our proposals to incur the ire of some political idealists on the right and the left. Nevertheless, for policy makers who are concerned about practical solutions to the grave injustices and high costs of mass incarcerations, our portfolio of options should be useful.  相似文献

The impact of a court service that is set up to enforce access orders is measured from the perspective of 70 children whose parents were program participants in the service. Children's perception of conflict diminished significantly over the 6-month period of service involvement. Children improved in their overall and school adjustment when visits with their noncustodial parents were more frequent. They were less depressed when they had quality relationships with both their mother and father. Children perceived more conflict as visits increased, but the negative impact was minimal.  相似文献
