This is a narrative review of the latest peer-reviewed social work literature on the child protection work with parents. Aiming to identify knowledge gaps, the study researches the mental health aspects of the implicit or explicit theoretical perspectives underpinning the assessment and intervention with parents. An electronic database search extracted 38 peer-reviewed journal articles. It was found that the theoretical perspectives the publications adopted were the managerial, the critical, the humanistic, the psychodynamic and the behavioural. The study identified mental health knowledge gaps in the assessment and intervention work with parents across all theoretical perspectives and stressed the need for process and effectiveness studies on the work with parents, under explicit theoretical perspectives. The study finally highlights the need for the social work profession to increase its mental health literacy through mental health education for students and practitioners alike. 相似文献

The prevalence of chronic conditions among children has been rising in the past four decades. Despite the policy relevance and plausible mechanisms through which child disability and severe early life health conditions can impact subsequent maternal reproductive behavior, there has been limited investigation of this question particularly in the US. Child disability or severe early life health problems such as very preterm birth (VPTB) and very low birth weight (VLBW) can constrain household resources to have another child but may also increase parental demand for healthy children and modify allocation of resources between children. Empirical assessment of this question is complicated by unobservables such as maternal health and preferences. We examine whether giving birth to a child with disabilities or severe adverse birth outcomes including VPTB and VLBW impacts subsequent maternal fertility. We employ a mother fixed-effect duration model for maternal fertility over time as a function of the proportion of previously born children with disabilities/health conditions in order to account for time-invariant unobservables, using merged data from the 1993 National Health Interview Survey and 1995 National Survey of Family Growth. We find no evidence that having disabled children reduces subsequent live births when using the mother fixed-effect model, in contrast to the classical model using within and between mother variation which suggests a fertility decline. Similarly, we find no evidence that having VPTB or VLBW children reduces fertility. Overall, our findings indicate no impact of child disability or health conditions on subsequent maternal fertility. Additional analyses excluding women who may qualify for AFDC show overall a similar pattern of results, suggesting that the findings may be generalizable post the AFDC. Time-varying unobservables may still be at work, but they likely result in an opposite (negative) bias toward reduction in fertility. 相似文献

We study a general class of piecewise Cox models. We discuss the computation of the semi-parametric maximum likelihood estimates (SMLE) of the parameters, with right-censored data, and a simplified algorithm for the maximum partial likelihood estimates (MPLE). Our simulation study suggests that the relative efficiency of the PMLE of the parameter to the SMLE ranges from 96% to 99.9%, but the relative efficiency of the existing estimators of the baseline survival function to the SMLE ranges from 3% to 24%. Thus, the SMLE is much better than the existing estimators. 相似文献

Forecasters typically select a statistical forecasting model from among a set of alternative models. Subsequently, forecasts are generated with the chosen model and reported to management (forecast consumers) as if specification uncertainty did not exist (i.e., as if the chosen model were the “true” model of the forecast variable). In this note, a well-known Bayesian model-comparison procedure is used to illustrate some of the ambiguities and distortions of forecasts that do not reflect specification uncertainty. It is shown that a single selected forecasting model (however chosen) will generally misstate measures of forecast risk and lead to point and interval forecasts that are misplaced from a decision-theoretic point of view. 相似文献

This paper presents a new linear model methodology for clustering judges with homogeneous decision policies and differentiating dimensions which distinguish judgment policies. This linear policy capturing model based on canonical correlation analysis is compared to the standard model based on regression analysis and hierarchical agglomerative clustering. Potential advantages of the new methodology include simultaneous instead of sequential consideration of information in the dependent and independent variable sets, decreased interpretational difficulty in the presence of multicollinearity and/or suppressor/moderator variables, and a more clearly defined solution structure allowing assessment of a judge's relationship to all of the derived, ideal policy types. An application to capturing policies of information systems recruiters responsible for hiring entry-level personnel is used to compare and contrast the two techniques. 相似文献

This paper explores how incorporating localized historical acts of racial injustice into Sociology courses can have a variety of pedagogical and social impacts. The use of one such event, the 1918 lynching of 13 people in South Georgia, led to the formation of the Mary Turner Project (MTP). We document the organization’s work as well as its impact on students and the region, as seen through the lens of public sociology. The MTP installed an official road marker to memorialize the lynching, intervened in a campus controversy involving the Confederate flag, hosted numerous commemoration events, and did classroom-based research and hosted community discussions on lynching and slavery in the local area. Drawing from organizational documents, the paper explores how ‘digging up the past’ and the experience of the MTP may serve as a model for critical sociologists who teach courses on social inequalities and want to make those courses more applicable to people’s every day lived experience. 相似文献

Chronic noncommunicable diseases (NCDs) in low‐ and middle‐income countries have recently provoked a surge of public interest. This article examines the policy literature—notably the archives and publications of the World Health Organization (WHO), which has dominated this field—to analyze the emergence and consolidation of this new agenda. Starting with programs to control cardiovascular disease in the 1970s, experts from Eastern and Western Europe had by the late 1980s consolidated a program for the prevention of NCD risk factors at the WHO. NCDs remained a relatively minor concern until the collaboration of World Bank health economists with WHO epidemiologists led to the Global Burden of Disease study that provided an “evidentiary breakthrough” for NCD activism by quantifying the extent of the problem. Soon after, WHO itself, facing severe criticism, underwent major reform. NCD advocacy contributed to revitalizing WHO's normative and coordinative functions. By leading a growing advocacy coalition, within which The Lancet played a key role, WHO established itself as a leading institution in this domain. However, ever‐widening concern with NCDs has not yet led to major reallocation of funding in favor of NCD programs in the developing world. 相似文献

While much attention has been devoted to measuring levels of social mobility over time, less attention has been given to the possibility of changing pathways to social mobility. This paper examines pathways from social origins to socio-economic destinations in midlife for two British cohorts, born in 1958 and 1970 respectively, using Structural Equation Modelling (SEM). We address the roles of cognitive attainment, private schooling and educational attainment in mediating the link between social origins and destinations. Have these mechanisms become more or less important over time, in a context of structural change in the state schooling system and educational expansion? We find that private schools displayed greater academic selectivity and an increased link to high levels of educational attainment for the younger cohort. Essentially, private schools adapted to changing circumstances, becoming more academically selective and less socially selective, and more focused on educational credentials. Childhood social origins were less strongly linked to childhood cognitive scores in the younger cohort, but cognitive scores were also more weakly linked to educational attainment for this cohort. We also find a decreased association between social origins and educational attainment for the younger cohort. While the finding that educational inequalities weakened over this time period is positive, the lack of a corresponding reduction in the overall link between social origins and destinations suggests that reducing educational inequalities was not sufficient to increase social mobility when accompanied by countervailing changes in the role of private schools. 相似文献
