ECONOMIC ROULETTE

Complementing previous literature on welfare reform and the character of jobs in the low-wage labour market, we illustrate the lack of regularity and security that mark the jobs held by many low-income mothers. To do so, we present a typology of mothers’ work patterns and illustrate their experiences through case examples. Our qualitative analysis of longitudinal pathways-to-work in three cities involved an examination of the experiences of 99 diverse, low-income working mothers with a young child. The work patterns that emerged from this analysis include: continuous duration of a single job; multiple job spells; underemployment; and churning in and out of employment. Findings indicate that a complicated ‘coming together’ of well-paying stable jobs, consistent aid from public systems and stable family networks are necessary for mothers to take even the first steps into stable employment.     

Optimal adaptive sequential designs for crossover bioequivalence studies

In prior works, this group demonstrated the feasibility of valid adaptive sequential designs for crossover bioequivalence studies. In this paper, we extend the prior work to optimize adaptive sequential designs over a range of geometric mean test/reference ratios (GMRs) of 70–143% within each of two ranges of intra‐subject coefficient of variation (10–30% and 30–55%). These designs also introduce a futility decision for stopping the study after the first stage if there is sufficiently low likelihood of meeting bioequivalence criteria if the second stage were completed, as well as an upper limit on total study size. The optimized designs exhibited substantially improved performance characteristics over our previous adaptive sequential designs. Even though the optimized designs avoided undue inflation of type I error and maintained power at 80%, their average sample sizes were similar to or less than those of conventional single stage designs.

The Therapeutic Action of Play in the Psychodynamic Treatment of Children: A Critical Analysis

This paper critically appraises the therapeutic action of play in psychodynamic child therapy and identifies obstacles to utilizing play therapeutically with children. An examination of the functions of action and verbal means of communication as well as their roles in shaping therapeutic relationships in treating children is provided in light of recent theoretical advances. The significance of engaging children directly through play and for redressing the balance between action and verbalization in child therapy is discussed.

Rates of missing responses in personal digital assistant (PDA) versus paper assessments

This article describes rates of missing item responses in personal digital assistant (PDA) assessments as compared to paper assessments. Data come from the evaluation of a classroom-based leisure, life skills, and sexuality education program delivered to high school students in Cape Town, South Africa. Analyses show that the paper assessments had much higher rates of missing-ness than PDA assessments. This association is moderated by item order. Certain analyses also suggest that paper assessments have higher rates of missingness for items pertaining to participants' sexual behavior. Implications of these results for evaluation research will be discussed.     

Understanding intimate partner violence against women in the rural South

Most U.S. intimate partner violence (IPV) research to date has been limited to women residing in urban areas, with the small body of research focusing on rural populations being primarily qualitative. In this case-control study of Southern rural women, while many factors are consistent with those found in urban settings, unlike findings elsewhere, IPV risk appears to increase with age, and race showed no increased risk. Furthermore, in rural areas where guns are more acceptable than in other parts of the United States, partners of IPV victims are considerably more likely to carry weapons than partners of nonabused women. Given the geographic limitations to police and medical response to severe IPV in a rural setting, an improved understanding of IPV risk among this population can aid health care providers in ascertaining risk before it escalates further.     

香港对新移民的管理和安置

与复杂的跨国网络与跨界互动相比,公民身份却划分了清晰的边界.香港回归中国主权后,对其公民身份的类别划分带来了极大的挑战.依照香港基本法中对居留权的定义,很大一部分--近一百六十七万人--可以享有这个权利,反映出香港与内地的跨界社会关系有着复杂历史.尽管香港与内地的社会和经济高度统一,但其边界仍然严格限制了人口从内地向香港流动.这种既统一又分离的状况导致了一种复杂的对立,部分地反映在关于居留权的争论.即使那些已经成功移民香港的内地居民也面临着各种挑战,其中最严峻的是怎样在香港这样一个住房价格最高的城市中获得可以负担的住所.因为新移民无法申请公营房屋,但这些房屋却占香港房屋总数的一半.而其私人住房的价格又是世界上最贵的.     

Do fertility transitions influence infant mortality declines? Evidence from early modern Germany

The timing and sequencing of fertility transitions and early-life mortality declines in historical Western societies indicate that reductions in sibship (number of siblings) may have contributed to improvements in infant health. Surprisingly, however, this demographic relationship has received little attention in empirical research. We outline the difficulties associated with establishing the effect of sibship on infant mortality and discuss the inherent bias associated with conventional empirical approaches. We offer a solution that permits an empirical test of this relationship while accounting for reverse causality and potential omitted variable bias. Our approach is illustrated by evaluating the causal impact of family size on infant mortality using genealogical data from 13 German parishes spanning the sixteenth, seventeenth, eighteenth, and nineteenth centuries. Overall, our findings do not support the hypothesis that declining fertility led to increased infant survival probabilities in historical populations.
