The current study examined the impact of the Gulf Oil Spill and Hurricane Katrina, environmental attitudes, and environmental action among residents of the Mississippi Gulf Coast. The authors sought to determine if disaster impact, worry about the environment, or connection to nature was associated with environmental action following the oil spill and in general. We hypothesized that disaster impact and environmental attitudes would be significantly associated with environmental action. Surveys were administered to 1,108 individuals receiving mental health services in connection with the Gulf Oil Spill. Results indicated that disaster impact was correlated with environmental worry, connection to nature, and action. Additionally, environmental worry and connection to nature were significantly associated with action, as were the effects of Hurricane Katrina to a lesser degree. This study supplements the existing literature by examining environmental attitudes, disaster impact, and their association with environmental action following two disasters.  相似文献

The Precautionary Principle has provided the foundations for building a new risk regulatory pattern under scientific uncertainty. This paper investigates how classical economic theory may, or may not, justify the Precautionary Principle. It examines the link between irreversibility, the prospect of increasing information over time and risk management. In doing so, it brings closer the notion of option value to that of precaution. Using a general modelling framework, it identifies the conditions so that the Precautionary Principle is an efficient economic guideline. It also explains why precautionary policies are not likely to emerge in a competitive economy or in the presence of a global pollution problem.  相似文献

This article deals with the problem of breakdown in different types of out‐of‐home care (foster care/residential care) for Swedish teenagers. How often are such placements prematurely terminated against the wishes and intentions of child welfare authorities? Which factors appear to increase or decrease the risk of placement breakdown? The sample consists of a national cohort of 776 youths who started 922 placements during 1991. Every placement was followed in municipal case files for a maximum period of five years. Between 30 and 37% of all placements were prematurely terminated, the exact figure depending on whether a narrow or wide definition of breakdown was applied. The lowest rates of breakdown were found in kinship care and secure units, the highest in non‐kinship foster homes. Teenagers who display antisocial behaviour and/or have mental health problems constitute a high‐risk category for most types of out‐of‐home care, but especially in non‐kinship foster homes. Risk factors in relation to breakdown were analysed in the four main forms of Swedish out‐of‐home care separately (foster homes, privately/publicly run residential care and secure units). The analysis pointed out that risk factors are not the same in all types of care, but antisocial behaviour at time of placement increased the risk in most forms of care. Prior research indicates that placement breakdown is a major problem of child welfare in other countries, and this study found that Sweden is no exception.  相似文献

Programmes providing services to children and families often face the challenge of assessing not only the child referred, but also the child’s family system and its individual members. Recognizing that household/family members can cause, contribute to or affect a child’s problems requires that human service agencies utilize assessment tools capable of assessing family members across the lifespan. The literature references many assessment tools used by clinical programmes in mental‐health settings that are not well suited to use in social service agencies with multidisciplinary staff at different skill levels. As a response to this dilemma, the authors have developed the Collaborative Assessment of Life Functioning (CALF), a user‐friendly tool that assesses various areas of life functioning. Based on Maslow’s motivation theory, person‐in‐environment and systems theories, the CALF can be used with various client systems. This paper describes the development of the tool, its purpose and use, the importance of assessment tools in the helping process and considerations for agencies wishing to use an assessment tool like the CALF. The authors also discuss the applicability of the CALF in human services and social service agency settings and with diverse client populations.  相似文献

The maximum likelihood and maximum partial likelihood approaches to the proportional hazards model are unified. The purpose is to give a general approach to the analysis of the proportional hazards model, whether the baseline distribution is absolutely continuous, discrete, or a mixture. The advantage is that heavily tied data will be analyzed with a discrete time model, while data with no ties is analyzed with ordinary Cox regression. Data sets in between are treated by a compromise between the discrete time model and Efron's approach to tied data in survival analysis, and the transitions between modes are automatic. A simulation study is conducted comparing the proposed approach to standard methods of handling ties. A recent suggestion, that revives Breslow's approach to tied data, is finally discussed.  相似文献

This research explores the perceptions of 60 parents whose children, aged from three to nine, had been involved in bullying, as defined under the Safe Schools Act and the Code of Conduct. Some of these children had been suspended from school, while others were potential candidates for suspension. These parents were recruited from Ottawa's two French-language school boards to participate in qualitative interviews between June 2000 and June 2002. The aim of this research was to cast new light on the perceptions of parents and schools with regard to their relationships, and on the role of school social workers in maintaining and enhancing collaborative partnerships.

The desire of some parents to be involved in the decisions concerning remedial action taken to address their child's aggressive behaviour touched a raw nerve in some schools. Nonetheless, when schools and parents ultimately recognize the daily challenges that both parties face, and a shared plan of action develops therein, the path to effective collaboration becomes clear. Early intervention on the part of school social workers gives them an edge in their efforts as mediators. They seize every opportunity to initiate different collaborative approaches between schools and parents, so that the issue of bullying can be handled in a more respectful way for everyone.  相似文献

A widely shared intuition holds that individual control over money matters for the decision process within the household and the subsequent distribution of resources and welfare. As a consequence, there are good reasons to depart from the unitary model of the household and to explore the possibilities offered by models of the family accounting for several decision makers in the household and for the potential impact of tax reforms on the balance of power. This paper summarizes both the methodological and empirical findings presented in the next three papers of this special issue of the Review of the Economics of the Household. This series of contributions primarily entails a concrete comparison of the policy implications of the choice between the unitary and a particular multi-person representation: the collective representation. On the one hand, it suggests a methodology to implement the collective model of labor supply in a realistic context where participation is modeled together with working hours, and where the full tax-benefit system is accounted for. On the other hand, the empirical part relies on comprehensive simulations of tax reforms in Belgium, France, Germany, Italy, Spain, and the United Kingdom, and allows to quantify the distortions that may affect policy recommendations based on the unitary model.

We use a French firm‐level data set containing 13,000 firms over the period 1994–2004 to analyze the relationship between credit constraints and firms’ R&D behavior over the business cycle. Our main results can be summarized as follows: (i) R&D investment is countercyclical without credit constraints, but it becomes procyclical as firms face tighter credit constraints; (ii) this result is only observed for firms in sectors that depend more heavily upon external finance, or that are characterized by a low degree of asset tangibility; (iii) in more credit‐constrained firms, R&D investment plummets during recessions but does not increase proportionally during upturns.  相似文献
