International income poverty measurement: which way now?

We critically review conceptual and empirical issues surrounding the derivation of the international poverty line, expressed in PPP-adjusted dollars and linked to various rounds of the International Comparison Program (ICP). We find that there are some limitations in the current estimation of these lines, but show that statistically superior methods lead to lines that are relatively robust and confirm the $1.25 using 2005 PPPs and suggest $1.67–1.71 using 2011 PPPs (or close to the $1.90 proposed by the World Bank if we follow the World Bank’s approach of adjusting inflation rates in some countries); they also roughly confirm the current shape of the proposed ‘weakly relative’ poverty line. Using the new absolute line based on 2011 PPPs would lead to substantially lower poverty in our estimation. The extent of the decline depends on whether and how one treats China, India, and Indonesia differently from other countries in the 2005 and 2011 PPPs. More seriously, we note that the dependence on successive ICP rounds creates conceptual and empirical problems that have become worse over time so that we suggest that it would be best to consider alternatives to the current reliance on ICP rounds and the resulting PPPs. As a short-term solution we propose to fix the international poverty line in national currencies using either the 2005 or 2011 level; in the medium term, we argue for global poverty measurement based on internationally coordinated national poverty measurement.     

Learning to be seen: the depiction of encounters between Israeli and newcomer children in children’s literature

Books written for and about children may serve to convey central cultural tenets to new members of society. This paper looks at the depiction of encounters between newcomer and locally born children in contemporary Hebrew literature aimed at teenage readers and presents the major resources and practices by means of which the newcomer protagonists are portrayed as coming to find their place in the new society. The paper suggests that, rather than introducing Israeli‐born readers to newcomer cultures, as might be expected in the current ideological climate of cultural pluralism, these books serve as a means of conveying to children and young people socially sanctioned modes of coming to belong to Israeli society.     

Some asymptotic results on generalized penalized spline smoothing

Summary.  The paper discusses asymptotic properties of penalized spline smoothing if the spline basis increases with the sample size. The proof is provided in a generalized smoothing model allowing for non-normal responses. The results are extended in two ways. First, assuming the spline coefficients to be a priori normally distributed links the smoothing framework to generalized linear mixed models. We consider the asymptotic rates such that the Laplace approximation is justified and the resulting fits in the mixed model correspond to penalized spline estimates. Secondly, we make use of a fully Bayesian viewpoint by imposing an a priori distribution on all parameters and coefficients. We argue that with the postulated rates at which the spline basis dimension increases with the sample size the posterior distribution of the spline coefficients is approximately normal. The validity of this result is investigated in finite samples by comparing Markov chain Monte Carlo results with their asymptotic approximation in a simulation study.     

Welfare State Transformation, Childcare, and Women's Work in Russia

The paper analyzes the transformation of the Russian welfarestate during the transition period, through the prism of formalcare provision in three distinct categories: childcare services,maternity/parental leave provisions, and in-home caregivingand other family allowances— in both Soviet and post-Sovietperiods. It shows that, since the 1990s, Russia has undergonesignificant structural reforms of its social, political, andeconomic systems, including childcare. Such reforms were notlimited to changes in the welfare state, but also included deepideological changes. These changes involved a transformationin the Russian welfare regime, leading towards a neofamilialistmodel of care. The paper illustrates the implications of thenew childcare policy mix on the position of women in the labormarket, utilizing the Russian Longitudinal Monitoring Surveydata.     

Treatments of non-metric variables in partial least squares and principal component analysis

This paper reviews various treatments of non-metric variables in partial least squares (PLS) and principal component analysis (PCA) algorithms. The performance of different treatments is compared in an extensive simulation study under several typical data generating processes and associated recommendations are made. Moreover, we find that PLS-based methods are to prefer in practice, since, independent of the data generating process, PLS performs either as good as PCA or significantly outperforms it. As an application of PLS and PCA algorithms with non-metric variables we consider construction of a wealth index to predict household expenditures. Consistent with our simulation study, we find that a PLS-based wealth index with dummy coding outperforms PCA-based ones.     

Still stressful after all these years: a review of lesbians' and bisexual women's minority stress

This article reviews the conceptualization of, and empirical literature on, lesbians' and bisexual women's sexual minority stress. In much of the early research, the experiences of sexual minority women and men were considered together (or women's experiences were inferred from men's), obscuring important differences. There is empirical and theoretical justification to consider the experiences of women and men separately and to develop and evaluate comprehensive models of sexual minority stress for women. Existing conceptualizations of sexual minority stress that include assessment of discrimination, victimization, harassment, concealment, internalized homonegativity may be applied, and perhaps adapted, to facilitate understanding of the unique stressors associated with women's sexual minority status. Future research must include mediators of the relationship between stressors and outcomes such as individual (e.g., coping and resilience) and group (e.g., social support, identification with a sexual minority community) resources. It is also essential to understand what factors may buffer the deleterious effects of these stressors.     

Pathways to early coital debut for adolescent girls: a recursive partitioning analysis

This study examined pathways to early coital debut among early to middle adolescent girls in the United States. In a two-year longitudinal study of 104 adolescent girls, recursive partitioning (RP) analyses were conducted to examine the specific factors that were related to engaging in first intercourse by the 10th grade among adolescent girls who had not yet engaged in sexual intercourse by the 8th grade. RP analyses identified subsamples of girls who had low, medium, and high likelihoods of engaging in early coital debut based on six variables (i.e., school aspirations, early physical intimacy experiences, depression, body objectification, body image, and relationship inauthenticity). For example, girls in the lowest likelihood group (3% had engaged in sex by the 10th grade) reported no prior experiences with being touched under their clothes, low body objectification, high aspirations to complete graduate education, and low depressive symptoms; girls in the highest likelihood group (75% had engaged in sex by the 10th grade) also reported no prior experiences with being touched under their clothes, but had high levels of body objectification. The implications of these analyses for the development of female adolescent sexuality, as well as for advances in quantitative methods, are discussed.     

DOES BEAUTY MATTER IN UNDERGRADUATE EDUCATION?

Physically attractive individuals achieve greater success in terms of earnings and status than those who are less attractive. However, whether this “beauty premium” arises primarily because of differences in ability or confidence, bias, or sorting remains unknown. We use a rich dataset from a women's college to evaluate each of these three mechanisms at the college level. We find that students judged to be more attractive perform significantly worse on standardized tests but, conditional on test scores, are not evaluated more favorably at the point of admission, suggesting that more attractive people do not possess greater abilities at the beginning of college. Controlling for test scores, more attractive students receive only marginally better grades in some specifications, and the magnitudes of the differences are very small. Finally, there is substantial beauty‐based sorting into areas of study and occupations. (JEL J16, I21, I23)     

To Help or Not to Help? Factors that Determined Helping Responses to Katrina Victims

Major research findings regarding individual helping behavior are reviewed and analyzed in light of the events during and after Hurricane Katrina. Implications from traditional and contemporary theories of psychology are examined. The discussion addresses both intrapersonal and contextual (psychosocial and situational) factors related to individual helping behavior in the context of real world events around the hurricane. In addition, the article contains implications for public policy and suggestions for policy makers.
