University–agency partnerships funded by Title IV-E encourage students to enter the child welfare field by providing student stipends, thus supporting child welfare agency workforce development. This article examines the literature and historical roots of Title IV-E and other partnerships, identifies common structures and outcomes, and discusses the extent to which a structured development and change process supports the California partnership’s core mission to integrate the education and practice communities in child welfare. The partnership is teleological in nature, using a social exchange approach to advance mutuality and a full spectrum of benefits for universities and agencies. Models and best practice elements are presented as examples of how university–agency partnerships may enhance child welfare service delivery. 相似文献

Although championed by the Marquis the Condorcet and many others, majority rule has often been rejected as indeterminate,
incoherent, or implausible. Majority rule's arch competitor is the Borda count, proposed by the Count de Borda, and there
has long been a dispute between the two approaches. In several publications, Donald Saari has recently presented what is arguably
the most vigorous and systematic defense of Borda ever developed, a project Saari has supplemented with equally vigorous objections
to majority rule. In this article I argue that both Saari's objections to majority rule and his positive case for the Borda
count fail. I hold the view that defenders of Condorcet cannot muster arguments to convince supporters of Borda, and vice
versa, but here I am only concerned to show that the Count de Borda cannot beat the Marquis de Condorcet. Saari's approach
displays what I take to be widespread fallacies in reasoning about social choice worthy of closer analysis. This debate bears
on important questions in the philosophy of social choice theory. 相似文献

This study determined the shape of trajectories from ages 13 to 19 of 4 types of dating abuse perpetration and examined whether the demographic characteristics of sex, minority status, socioeconomic status, and family structure systematically explained variation in the trajectories. The data are from 5 waves of data collected from 973 adolescents participating in the control group of a randomized trial. The mean trajectory for psychological dating abuse was positive linear, but the mean trajectories were curvilinear for moderate physical, severe physical, and sexual dating abuse. At all ages, boys reported more severe physical and sexual dating abuse than girls, minorities reported more moderate and severe physical dating abuse than Whites, adolescents in single‐parent households reported more psychological and severe physical dating abuse than those in 2‐parent‐households, and parental education was negatively associated with psychological and moderate physical dating abuse perpetration. The findings have implications for future research and for practice. 相似文献

The tail Yt = Xt – u of a random sequence {Xt ∈ , t ∈ } with identically distributed Xt is approximated by the generalized Pareto distribution according to the extreme value theory, wherein Yt occurs in clusters because of the dependence in the random sequence. Nevertheless, the parameters of the generalized Pareto distribution are estimated by the same methods as in the case of independent and identically distributed Yt, provided that there is independence between the clusters of Yt. The estimation variances and confidence intervals can be estimated by the jackknife method. The approaches are theoretically discussed and verified by extensive numerical researches. 相似文献
