The significance of uprightness: parents’ reflections on children’s responses to a hands-free walker for children

The benefits and drawbacks of facilitating independent walking in children with physical mobility impairments, such as cerebral palsy, remain to be determined. This knowledge gap creates decision dilemmas about which mobility practices parents and children should adopt and rehabilitation professionals should foster. These dilemmas are reflected in continuing debates about allocation of time, effort and resources to optimize walking versus encouraging use of manual or powered wheelchairs. Recent studies have reported only modest measurable walking progress for severely disabled children using hands-free walkers. Despite these seemingly disappointing results, parents remained highly motivated to encourage their children to use these walking devices and appraised them very positively. In the present paper, we suggest that parents’ symbolic value of their children assuming upright comportment may explain why they perceive hands-free walkers positively and why they are so motivated to devote much time and effort to improving independent, walking-based mobility of their children.     

Understanding congressional foreign policy innovators: Mapping entrepreneurs and their strategies

Since World War II, a small group of assertive MCs have chosen to lead on foreign policy issues about which they care, without waiting on the administration to take action. Significant foreign policy innovation has been the result. From the coldest days of the Cold War to the changed circumstances after 9/11, important congressional initiatives attributable to a few key individuals can be found. Drawing on an original quantitative dataset of post-World War II congressional foreign policy activity, interviews with members and their staffs, and primary and secondary research, this paper: (a) discusses the characteristics and impact of these policymakers; (b) develops categories of entrepreneurs, drawn from issues to which entrepreneurs have devoted their attention; and (c) derives strategies of entrepreneurship drawn from the activities and avenues utilized by the entrepreneurs.     

Estimation of the linear-plateau segmented regression model in the presence of measurement error

It is well known that when the true values of the independent variable are unobservable due to measurement error, the least squares estimator for a regression model is biased and inconsistent. When repeated observations on each x_i are taken, consistent estimators for the linear-plateau model can be formed. The repeated observations are required to classify each observation to the appropriate line segment. Two cases of repeated observations are treated in detail. First, when a single value of y_i is observed with the repeated observations of x_i the least squares estimator using the mean of the repeated x_i observations is consistent and asymptotically normal. Second, when repeated observations on the pair (x_i, y_i ) are taken the least squares estimator is inconsistent, but two consistent estimators are proposed: one that consistently estimates the bias of the least squares estimator and adjusts accordingly; the second is the least squares estimator using the mean of the repeated observations on each pair.     

Evaluation of the What's Real: Myths & Facts about Marriage Curriculum: Differential Impacts of Gender*

ABSTRACT

What’s Real is a high school marriage education curriculum designed to teach students how to develop healthy relationships and marriages. This study evaluated the effectiveness of this curriculum with 206 high school students who were in either the What’s Real group or a control group. Findings suggest that the curriculum increases knowledge of healthy relationship concepts, positively impacts attitudes related to students’ willingness to be involved in pre- and postmarital counseling, and increases students’ attitudes toward cohabitation avoidance. Implications for further development of the curriculum and other implications for practitioners and policymakers are discussed.     

In quest of the banks set in spatial voting games

The Banks set (1(4):295–306, 1985) is one of the more important concepts in voting theory since it tells us about the sophisticated outcomes of standard amendment voting procedures commonly in use throughout the English speaking world (and elsewhere as well). While the properties of the Banks set for finite voting games have been extensively studied, little is known about how to find members of this set for majority rule spatial voting games involving possibly infinite agendas. We look at this question for two-dimensional games where voters have Euclidean preferences, and offer a variety of new results that delimit areas of the space that can be shown to lie within the Banks set, such as the Schattschneider set, the tri-median set, and the Banks line set—geometric constructs which we show to be nested within one another.     

Actuarial risk assessment in child protective services: Construction methodology and performance criteria

Purpose

To prevent the recurrence of child maltreatment, actuarial risk assessment can help child protective services (CPS) workers make more accurate and consistent decisions. However, there are few published articles describing construction methodologies and performance criteria to evaluate how well actuarial risk assessments perform in CPS. This article describes methodology to construct and revise an actuarial risk assessment, reviews criteria to evaluate the performance of actuarial tools, and applies a methodology and performance criteria in one state.

Methods

The sample included 6832 families who were followed for two years to determine whether they were re-reported and re-substantiated for maltreatment.

Results

Both the adopted and the revised tools had adequate separation and good predictive accuracy for all families and for the state's three largest ethnic/racial groups (White, Latino, and African American). The adopted tool classified relatively few families in the low-risk category; the revised tool distributed families across risk categories.

Conclusions

The revised tool classified more families as low-risk, allowing CPS to allocate more resources to higher-risk families, but at the cost of more false negatives.     

Practice standards in Australia: implications for social work education

In 2003, the Australian Association of Social Work launched Practice Standards that define minimal expectations for all social workers. The Practice Standards are outcome focused and specify what social workers are expected to achieve in the areas of Direct Practice, Service Management, Organizational Development and System Change, Policy, Research, and Education and Professional Development. This paper outlines the rationale for developing the Practice Standards, the process undertaken and the need for social work educators to build a curriculum that prepares students to be competent and effective in a complex working environment.     

A THEORETICAL INVESTIGATION OF PUBLIC ATTITUDES TOWARD SEX EDUCATION

Rates of teen pregnancy in the United States are significantly higher than those in most other industrialized nations. This is troubling in light of the consequences to teen mothers, their children, and society. Some suggest that teen pregnancies can be decreased by providing sex education in the public school system, while others believe that sex education is inappropriate for public school. Little research exists, however, on predictors of attitudes toward sex education, and most existing research is dated and lacks a theoretical framework. Guided by the seminal work of Ira L. Reiss, we examine the impact of labor shortages, religiosity, militarism, gender egalitarianism, regulation of sexuality, and a naturalistic view of sexuality on attitudes toward sex education. Results suggest that Hispanics, those with high levels of religiosity, and those who supported regulation of sexuality were significantly less likely to support sex education in public schools. Implications of the findings and directions for future research are discussed.
