In the debate over “maternal indifference” and, more generally, over the ways in which children were viewed and treated in the European past, the care of abandoned children has attracted a good deal of attention. Huge numbers of newborns were consigned to foundling homes in past centuries, and attempts to keep the children alive depended heavily on placing them with rural wetnurses and foster families. In general, scholars have portrayed these foster families as having little concern for the welfare of their charges. One consequence of this view is the presumed instability of foster home arrangements for foundlings. Using archival sources, this article investigates the relationships between foster families and foundlings by examining the lives of babies abandoned at the foundling home in Bologna, Italy over the course of the nineteenth century. The study provides grounds for questioning the received wisdom on the subject of foundling care in nineteenth-century Italy and beyond.  相似文献

Very little is known about how relationships between people with disabilities and their paid support workers are positioned in policy. With the policy shift toward choice of provider, individualised approaches, person centredness and self‐directed funding, the nature of their relationship assumes a more prominent role in the quality of support practice. The policy analysis in this article explores the extent to which current disability policy acknowledges, promotes, or diminishes the relationships between people with disabilities and workers, in their organisational context. It uses Honneth's conditions for recognition—love (cared for), rights (respected) and solidarity or social esteem (valued)—to understand how policy positions mutuality in the relationship. The policy review applied a three‐stage process: categorisation of policies, textual analysis and content analysis to policy documents at four levels—international, Australian federal, state and organisational in two case studies. The analysis revealed that while a rights framework is explicit in most policies, the emphases on the conditions for recognition within a relationship between people with disabilities and workers are compromised in instructional policies that attempt to manage the tension between choice and risk, particularly at the organisational level.  相似文献

Doping control laboratories accredited by the World Anti-Doping Agency (WADA) require criteria that allow endogenous steroids to be distinguished from their synthetic analogues in urine. Methodology based on "looking outside the metabolic box" was used in this study to identify diagnostic urinary markers of 4-androstenediol (4-ADIOL) administration. Androst-2,4-diene-17-one and androst-3,5-diene-17-one are proposed to be formed in urine from acid-catalyzed hydrolysis of 4-ADIOL sulfoconjugate, a major phase II metabolic product of 4-ADIOL. The presence of these markers in the routine gas chromatography-mass spectrometry (GC-MS) steroid screen was suitable to identify samples requiring confirmation by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) - to measure the carbon isotope ratio (δ(13)C) of the androstdiene markers and confirm their likely synthetic origin based on depleted (13)C content.  相似文献

So ubiquitous is reference to collaboration in policy documents that it is in danger of being ignored altogether by service deliverers who are not clear about its rationale, how it is built, or its real value. This is evident in the child and family services context where for example the National Framework for Protecting Australia's Children calls for collaboration and a ‘shared responsibility’ across the state, Commonwealth and the non‐government sectors to keep children safe and well. This article describes a project undertaken to analyse and ultimately increase levels of collaboration between state and Commonwealth government family service providers. The research reinforced an important message that levels of collaboration should align with the vulnerability of children and their families: the greater the level of risks to children, the greater the level of collaboration needed within and between systems to keep children safe.  相似文献

This is the second article in a series of three that examines the legal role of medical professionals in decisions to withhold or withdraw life-sustaining treatment from adults who lack capacity. This article considers the position in Queensland, including the parens patriae jurisdiction of the Supreme Court. A review of the law in this State reveals that medical professionals play significant legal roles in these decisions. However, the law is problematic in a number of respects and this is likely to impede medical professionals' legal knowledge in this area. The article examines the level of training medical professionals receive on issues such as advance health directives and substitute decision-making, and the available empirical evidence as to the state of medical professionals' knowledge of the law at the end of life. It concludes that there are gaps in legal knowledge and that law reform is needed in Queensland.  相似文献

Experiments have become an increasingly common tool for political science researchers over the last decade, particularly laboratory experiments performed on small convenience samples. We argue that the standard normal theory statistical paradigm used in political science fails to meet the needs of these experimenters and outline an alternative approach to statistical inference based on randomization of the treatment. The randomization inference approach not only provides direct estimation of the experimenter’s quantity of interest—the certainty of the causal inference about the observed units—but also helps to deal with other challenges of small samples. We offer an introduction to the logic of randomization inference, a brief overview of its technical details, and guidance for political science experimenters about making analytic choices within the randomization inference framework. Finally, we reanalyze data from two political science experiments using randomization tests to illustrate the inferential differences that choosing a randomization inference approach can make.  相似文献

Purpose. The ideologically based view of intimate partner violence has traditionally influenced policy and practice in modern western nations and dominated cross‐national research and practice. This review considers the validity of the position statement of a British organization responsible for accrediting many male perpetrator programmes in the statutory, voluntary, and private sector as an example of this ideological influence. Method. The position statement, informed by the patriarchal view of partner violence, is evaluated using empirical evidence from various branches of the social sciences, including psychology, that have not been guided by the patriarchal view. Results. Overwhelming empirical evidence is presented, which refutes ideologically driven assumptions that have been put forward to guide current practice and evaluation of it. Conclusions. This review highlights the need to investigate intimate partner violence from a scientific and gender‐inclusive perspective. The implications for psychological practice are discussed.  相似文献
