Responses to prenatal opioid and alcohol abuse: A review of US and Australian mandatory reporting laws

Prenatal substance use, specifically opioid and excessive alcohol use, can cause significant adverse effects for the unborn foetus in both the short-and long-term. Responses by state social systems occur on a spectrum of prevention and early intervention to support mothers. Some but not all states include reporting duties, so that professionals made aware of the situation may alert agencies that can intervene to provide appropriate support. This article will review legal duties to report maternal substance use during pregnancy in the US and Australia. We identify variations in these laws regarding who is required to report, what circumstances must be reported and what indicates child abuse or neglect. Inconsistencies in laws raise questions about the nature of different approaches, and how reforms might be made to improve provision of support. Informed by the medical literature, the contemporary context and federal policy in the US, we make recommendations for reform, and for the appropriate response to such reports.

ESTIMATORS BASED ON KENDALL'S TAU IN MULTIVARIATE COPULA MODELS

The estimation of a real‐valued dependence parameter in a multivariate copula model is considered. Rank‐based procedures are often used in this context to guard against possible misspecification of the marginal distributions. A standard approach consists of maximizing the pseudo‐likelihood. Here, we investigate alternative estimators based on the inversion of two multivariate extensions of Kendall's tau developed by Kendall and Babington Smith, and by Joe. The former, which amounts to the average value of tau over all pairs of variables, is often referred to as the coefficient of agreement. Existing results concerning the finite‐ and large‐sample properties of this coefficient are summarized, and new, parallel findings are provided for the multivariate version of tau due to Joe, along with illustrations. The performance of the estimators resulting from the inversion of these two versions of Kendall's tau is compared in the context of copula models through simulations.     

Psychometric properties of the Spanish version of the Environmental Action Scale (EAS) / Propiedades psicométricas de la versión española de la Escala de Acción Colectiva Ambiental (EACA)

The Environmental Action Scale (EAS) analyses engagement in civic actions which seek to have an environmental impact. The EAS has shown adequate psychometric properties when used with English-speaking samples, but there are no studies assessing how it works in other linguistic and cultural groups. The aim of the study is to present the Spanish version of the EAS along with evidence that supports the utility of the scale to be used in the Spanish population. The Spanish version obtained after the adaptation process was first administered to 277 participants. The results pointed to items that did not function adequately, so a revised version was created and administered to 286 participants. Validity evidence based on internal structure showed that the EAS consistently evaluates two dimensions of the construct: Participation Activities and Leadership Activities. Evidence based on relationships with other variables indicated that the construct is also related to other variables, such as environmental identity and moral convictions.     

Examining the influence of organizational characteristics on nonprofit commercialization

A growing body of literature discusses the (dis)advantages of nonprofit organizations becoming commercial by engaging in the sale of organizational services and products. However, when explaining this phenomenon, scholars tend to focus on resource uncertainty, thereby disregarding the organizational ability to commercialize. Complementing resource dependency theory with insights from contingency theory, this study presents arguments drawn from a comparative case study of six sociocultural nonprofits in Belgium. We find that, when resource uncertainty is similar, organizational differences in terms of commercial income can be explained by differences in (a) organizational origins, (b) professional capacity, and (c) types of tasks. We conclude that organizational characteristics can either enable or disable the ability of nonprofits to commercialize and consequently their ability to self‐sustain in an increasing challenging resource environment.

Working with Signs of Safety: Parents' perception of change

Signs of Safety (SoS) is an approach used to work with families involved with children's services that was developed in Australia during the 1990s. Despite the fact that it has been adopted by countries across the globe, the evidence for its effectiveness in relation to improved outcomes for children has not been established. This study attempted to take an initial step in measuring the impact of SoS on families. In the course of evaluating SoS in 10 areas across England, the authors collected data from social workers using the approach and from families with whom they were working who also gave permission for their case records to be examined. Where social workers were more confident about using SoS and had consistently applied its elements, more families reported improvements in their lives. Families with social workers who had higher confidence in using SoS were also more likely to say that they had achieved more than expected against their earlier stated goals and were more likely to report positively against self‐defined goals.

历史意识·本土意识·问题意识——2009年度文艺学研究热点扫描

2009年度能够被称为热点的文艺学研究问题大体仍然是新世纪以来重大问题论争的延续,但是历史意识、本土意识以及问题意识的增强却是文艺学研究进一步走向深化的表征.2009年,正是新中国成立六十周年,"前后三十年"使文艺学六十年的反思与回顾充满了复杂而纠葛的难题;在文艺学的本质论与建构之争中,争论双方虽在"本质有无"上有分歧,但均自觉放弃"本质主义思维"应该是难得的收获;围绕实践美学的逻辑起点和以"实践存在论"为代表的理论发展之争仍很激烈,甚至带上了个人意气;文化研究在淡化了与文学研究的边界之争之后,其自身的学科之惑和机制之难则成为近年来学者关注的重心.
