生物学理论作为科学哲学研究中的一个另类一直受到关注。它与传统科学模式间的差异是造成这种现象的原因之一。解读这种差异的根源,需要对生物学的理论基础以及理论结构给予充分的关注。生物学特有理论结构所表现出的多元语境与语义结构的复杂性,决定了对生物学理论基础的研究应当重视语义分析的方法,尤其是对理论本身进行语义分解并研究其中的语义关联问题,从而解读生物学模式作为一种不同于理化科学的特殊科学解释观的合理性。 相似文献

We examined how satisfied Finnish adoptive parents were with statutory pre-adoption counselling in inter-country adoptions. The data were collected through the Finnish Adoption Study using a retrospective survey measuring satisfaction with received pre-adoption counselling. All adoptive parents with a child under the age of 18, adopted from abroad between the years 1990 and 2007, were included. The sample of the study comprised parents of 1451 children and a total response rate of 55.7% was achieved. The data consisted of self-scored reports of satisfaction as well as open answer questions. Parent satisfaction and associated variables were analysed using chi-square and multiple logistic regression. Of the respondents, 81.7% reported satisfaction with the pre-adoption counselling they had received. The level of satisfaction was stable over time and did not differ according to service provider, whereas family type and sending country were associated with satisfaction. However the explanations for satisfaction were different for those services provided in units specialized in adoption and for those provided by municipal child protection services. The components found to explain satisfaction and dissatisfaction were experience, adoption knowledge, and attitude of the social worker, service accessibility and availability issues, as well as the content of the pre-adoption counselling offered. 相似文献

Family supporting foster care (FSFC) is a directly accessible, short-term and preventive form of foster care for children under the age of 12. Caregivers in this type of foster care need comprehensive support to deal with their complex tasks. In this contribution, the support needs arising from the behaviour of the foster child as well as concerning dealing with the biological parents of 85 Flemish FSFC-parents are examined, as these are areas FSFC-parents specifically ask support for. These support needs are evaluated for possible links with child and foster parent characteristics. More experienced foster parents and foster parents with a foster child showing more externalising problem behaviour ask for more support in managing the child's behaviour. 相似文献

Workfare is, at least in part, a policy response to changing labour markets and the expansion taking place in jobs that are low‐paid, irregular and insecure. For lone mothers, increasingly the focus of workfare policies, precarious employment creates special challenges. However, the nature of the jobs that are available to women on social assistance has received relatively little attention in the workfare literature, which focuses more on individual characteristics, supports to employment, and programme impacts. Drawing upon both primary and secondary sources and using Ontario, the province with the most developed workfare programme in Canada, this article examines the ways in which policies support and enforce precarious employment. The article also considers the implications of precarious employment for UK policy, which has not (yet) adopted workfare for lone mothers, although incremental steps in that direction are taking place as employment is increasingly viewed as the appropriate objective of income support programmes for lone mothers. 相似文献

This article shows how time works against parents with learningdifficulties in the child protection system and Children Actproceedings. The prevailing wisdom, embedded in policy and theliterature, is that delay in care cases is bad for the childand may jeopardize his or her future. This paper shows how thepressure to avoid delay might itself be harming some families,especially parents with learning difficulties. Drawing on interviewswith social work practitioners undertaken as part of a largerstudy, the authors describe the various forms of temporal discriminationthat impact on this group of disabled parents. They concludethat procedural time limits make it harder for parents withlearning difficulties to meet the standards and expectationsenforced by Childrens Services and the courts. 相似文献

In this article, we review what has been learned to date from the first 5 years of the Fragile Families and Child Wellbeing study about child support, fatherhood, and marriage. The article first describes the parents' circumstances at the time of the child's birth, then examines the trajectories of parents' relationships (with each other and others), fathers' financial contributions and other indicators of fathers' involvement with their children 5 years later; and finally reviews what has been learned about the effect of child support enforcement on these three aspects of families' lives. We find that most unmarried parents are either cohabiting or romantically involved at the time of the child's birth, but are a distinctly disadvantaged group as compared with married parents. Five years later, most of these parents are no longer romantically involved, however, most of the fathers are still seeing their children on a regular basis, and about half are contributing either formally or informally to their support. Strong child support enforcement appears to increase formal and decrease informal support from fathers, reduce marriage among parents, and have a weak positive effect on father involvement. More research is necessary to understand whether these findings are robust over time and across samples of unmarried parents. 相似文献

While the US Supreme Court was considering two related cases involving the constitutionality of same-sex marriage, one major question informing that decision was whether scientific research had achieved consensus regarding how children of same-sex couples fare. Determining the extent of consensus has become a key aspect of how social science evidence and testimony is accepted by the courts. Here, we show how a method of analyzing temporal patterns in citation networks can be used to assess the state of social scientific literature as a means to inform just such a question. Patterns of clustering within these citation networks reveal whether and when consensus arises within a scientific field. We find that the literature on outcomes for children of same-sex parents is marked by scientific consensus that they experience “no differences” compared to children from other parental configurations. 相似文献
