UK government policy encourages mothers of young children in low-income families to enter or return to work, via tax credit subsidies and support for childcare. Maternal employment is seen a central plank in the campaign against child poverty, both because it raises income immediately and because working now is seen as paving the way to better employment prospects in the future. But there is little evidence about medium- and long-term outcomes for mothers entering low-skilled employment. We know little about how likely such women are to remain in work, let alone how likely they are to progress to higher-skilled and better-paid jobs. This article uses the British Lone Parent Cohort, a data set which tracked lone mothers from 1991 to 2001, to examine employment trajectories for up to 560 mothers with a youngest child under five at the start of the period. It creates a typology of trajectories over the decade, identifying the share of women broadly stable in work, those remaining at home and those following unstable pathways between the two. It goes on to explore the factors associated with different pathways, asking whether individual and household characteristics, job characteristics, or changes in circumstances such as new health problems are most important. Finally, the article examines differences in wage progression across groups of women following different pathways, and similarly tries to identify the main factors associated with faster progress.  相似文献

In this paper, we extend the standard data envelopment analysis (DEA) model to include longer term top management goals. This extension is in recognition of the fact that benchmarking for decision making units (DMUs) is more than a purely monitoring process, and includes a component of future planning. The new model uses a goal programming structure to find points on the efficient frontier which are realistically achievable by DMUs, but at the same time achieving a closer approach to long term organizational goals (as distinct from the local performance of individual DMUs). Consideration is given to the possibility of adjusting constraints on the DMU by investment in extended inputs or new technologies, in which case minimization of associated investment costs becomes an additional management objective.  相似文献

The Prodigy Cultural Arts program provides art classes embedded with three types of self-regulation skills (problem solving, social skills, and anger management) in an after school community setting to at-risk youths. Empirical evidence supports the effectiveness of self-regulation skills programs and the arts in programs for at-risk youths, yet the impact of the environment on the youth participants is often ignored. This study examines neighborhood structural characteristics along with previously identified individual, mental health variables in school outcomes for adolescents attending the Prodigy Program. Findings suggest that neighborhood structural characteristics have some influence in program outcomes. Limitations of the study and future research are discussed.  相似文献

Repeated categorical outcomes frequently occur in clinical trials. Muenz and Rubinstein (1985) presented Markov chain models to analyze binary repeated data in a breast cancer study. We extend their method to the setting when more than one repeated outcome variable is of interest. In a randomized clinical trial of breast cancer, we investigate the dependency of toxicities on predictor variables and the relationship among multiple toxic effects.  相似文献

In preposterior analysis, Bayesians use an Expected-Net-Gain chart to identify the optimal sample size. This kind of chart, it turns out, is also an excellent educational vehicle for illustrating many of the reasons given for preferring sampling from a population over taking a census, preferring one type of sampling over another (e.g., stratified sampling rather than simple random sampling), or allocating part of a fixed budget to reduce systematic error rather than using it all to reduce sampling errors. The use of such a chart in a basic statistics course is described.  相似文献

A multidimensional block design (MBD) is an experimental design with d > 1 blocking criteria geometrically represented as a d-dimensional lattice with treatment varieties assigned to some or all nodes of the lattice. Intrablock analysis of variance tables for some special classes of two- and three-dimensional block designs with some empty nodes are given. Design plans and efficiencies for 31 two-dimensional designs, each universally optimal in defined classes of designs, and 7 three-dimensional designs, each nearly optimal in defined classes of designs, are listed in the appendices. A need for such designs is apparent when the blocking criteria are implemented successively and empty nodes do not represent wasted experimental units.  相似文献

Long-term stewardship is usually represented as a stable structural condition and portrayed as a source of competitive advantage to firms (including family businesses) that use it as a mode of governance. Less is known about how organizations engage with stewardship as a process. We embrace a process approach to report a case study about the unfolding of stewardship in a multi-business family group. We conclude that stewardship is a process marked by critical tensions and paradoxes; by exploring the nature of these we uncover further dimensions and responses to the paradoxes of stewardship.  相似文献

A brief review is made of the literature surrounding the use of contracts in social work and their adaptation into social work education in the form of Working Agreements. The operation of Working Agreements in fieldwork placements is then considered in some depth, based upon features which include differential participation, reciprocal accountability and explicitness. A variety of positive and negative aspects are identified and some limitations in the application of Working Agreements are suggested.  相似文献

The focus of this article is upon the way in which practice teachers and students considered individual and institutional racism and anti-racism in a sample of 40 placement reports. First of all we will examine the background to the development of CCETSW policies and requirements for social work courses and the way in which they consider racism and anti-racism. Then we will consider the limitations and aims of our research. We will present a brief summary of our findings which contrasts the content of the placement reports from two cohorts of students in 1995 and 1997, whose reports were prepared using two different placement report frameworks: one framework developed from CCETSW's 1989 guidelines, the other framework from the revised guidelines dating from 1995. We go on to consider in some depth the overall comments of practice teachers and students in the placement reports about work with black clients/users, the use of 'what if' scenarios and case studies. We continue by examining the way in which students considered the numbers of black people in the local population, and the use made by black people of the placement agencies. Also examination is made of multiple oppression, any challenges to racism made by students, differences in terminology used to consider issues associated with 'race' and the attention given to racism and anti-racism as future learning needs. Finally, we consider implications for future research and a summary of the findings.  相似文献
