A nonparametric procedure for the analysis of balanced crossover designs

The authors propose nonparametric tests for the hypothesis of no direct treatment effects, as well as for the hypothesis of no carryover effects, for balanced crossover designs in which the number of treatments equals the number of periods p, where p ≥ 3. They suppose that the design consists of n replications of balanced crossover designs, each formed by m Latin squares of order p. Their tests are permutation tests which are based on the n vectors of least squares estimators of the parameters of interest obtained from the n replications of the experiment. They obtain both the exact and limiting distribution of the test statistics, and they show that the tests have, asymptotically, the same power as the F‐ratio test.     

Social Class and Adolescents' Beliefs about Justice in Different Social Orders

We report on the justice beliefs of 4508 adolescents from 4 security societies in transition to market economies (i.e., Bulgaria, the Czech Republic, Hungary, and Russia) and from 2 opportunity societies (Australia and the United States). Using a multivariate analysis of variance (MANOVA), justice beliefs were examined as a function of type of society, social class, and gender. In the security societies, working-class teens wanted the state and schools to provide a safety net, while middle-class teens preferred that schools promote student autonomy and competition but also reported the most negative school climates of any group. In the opportunity societies, working-class youth believed success was based on individual merit, while middle class youth expressed more doubt about this connection .     

Thirty‐Year Trends in U.S. Adolescents' Civic Engagement: A Story of Changing Participation and Educational Differences

Using annual cross‐sectional data from Monitoring the Future, the present study examined trends in high school seniors' current and anticipated civic participation and beliefs over a 30‐year period. We examined overall trends and patterns based on youths' post‐high school educational plans. Findings point to declines in recent cohorts' involvement in conventional and alternative forms of engagement but greater involvement in community service. Regardless of period, the majority of youth said they intended to vote when eligible, but few expressed trust in the government or elected officials. All civic indicators showed significant differences based on youths' college aspirations: Youth who planned to graduate from a 4‐year college were more civically inclined than their peers with 2‐year or no college plans.     

The senses at the National Gallery: art as sensory recreation and regulation in Victorian England

ABSTRACT

In 1850, the keeper of the National Gallery in London described the museum as being frequented by “school boys eating bread and cheese” and country folk who “drew their chairs round and sat down, and seemed to make themselves very comfortable”. As for the pictures on the walls, these were smeared with the fingerprints of inquiring gallery-goers. The tension between the National Gallery as an unfussy place of recreation, in which visitors could enjoy themselves at their ease, and as a prim site of regulation, in which visitors must learn to exercise tight control over their behavior, played itself out in elite nineteenth-century debates over the role of the Gallery as a public space. This article examines nineteenth-century representations of the ideal sensory role of the National Gallery and its problematic actual sensory life. This leads into a discussion of the ways in which the National Gallery and other public art institutions were imagined to function as the soft fingertips of the long arm of the law, transforming social disorder into social order and destructive sensuality into compliant sensitivity.     

The future of sex mortality differentials in industrialized countries: A structural hypothesis

This paper advances the hypothesis that the future of sex mortality differentials in industrialized countries may depend on the future mortality rates of blue collar men. Data are presented to support the argument that mortality rates from ischemic heart disease for this population subgroup play a significant role in current differentials and, furthermore, that sexsocial class-mortality differentials correspond to social structural differences in protection against and/or exposure to health risks. Research and policy implications of this argument are addressed briefly.The views expressed in this paper are those of the authors and do not necessarily reflect the policy or views of the World Health Organization.     

On tests for normality of experimental error in ridge regression

Considered are tests for normality of the errors in ridge regression. If an intercept is included in the model, it is shown that test statistics based on the empirical distribution function of the ridge residuals have the same limiting distribution as in the one-sample test for normality with estimated mean and variance. The result holds with weak assumptions on the behavior of the independent variables; asymptotic normality of the ridge estimator is not required.     

World War II and Its Effect on the Sex Differential in Arrests: An Empirical Test of the Sex-Role Equality and Crime Proposition*

A common explanation for the decrease in the sex differential in arrests during World War II attributes it to a change in female sex-role behavior. Because of the wartime equalization of sex roles, particularly of expanding occupational roles of women, female arrest rates began to approach male rates. Two alternative explanations appear equally plausible: (1) changes in the sex-age structure of the population at risk and (2) changes in official reactions to female "sex offenders" over the prewar to wartime period, as reflected in the differentiation in types of crimes for which males and females were arrested during World War II. The analysis examines these two alternative explanations, and finds that: (a) by simply correcting for the sex-age structure of the population, the narrowing of the sex differential is reduced considerably; and (b) by taking into account type of crime, and specifically by omitting offense categories that reflect the paternalism and double standard of sexual morality in society, the narrowing of the sex differential disappears. Finally, the predicted special effects of World War II on female arrests for property crimes did not materialize.     

Powers and Limits of Transnational Corporations: The Case of ADM

Abstract This analysis employs the case of lysine price fixing involving the food‐processing transnational corporation (TNC) Archer Daniels Midland (ADM) and Asian‐based firms. In an “economy and society” conceptual framework grounded in the sociology of agriculture and food, we investigate the powers and limits of TNCs in the global era. We argue that TNCs maintain significant powers which allow them to avoid the laws and regulations of nation‐states. ADM was able to organize an illegal global cartel to control the world production and price of the feed supplement lysine. In addition, TNCs' actions in the global arena are limited by their inability to trust business partners and to organize and maintain systems of social control; these roles historically have been played by the nation‐state. We conclude that despite their significant powers, TNCs' contradictory position in the global arena provides opportunities that can be used to democratize society.     

Impact of a Group Prenatal Program for Pregnant Adolescents on Perceived Partner Support

This quasi-experimental study compared family formation and perceived partner support among pregnant adolescents in a prenatal care program. Participants were assigned to either an intervention group utilizing centering pregnancy (CP) prenatal care and case management, or to a comparison group receiving case management only. Partners were invited to participate in CP group sessions. This study included 173 predominantly minority pregnant adolescents ages 15–18 years who were enrolled in a prenatal program and followed one month postpartum. Family formation included living and relationship arrangements. Perceived partner support included six domains of perceived social provisions. Data were collected through participants’ self-reports using computer-assisted self-interviews. Changes in family formation and perceptions of partner support from baseline to postpartum did not differ between intervention and comparison groups. Male partners who attended at least one CP session were perceived as more supportive at both the beginning and end of the program than partners who did not attend any sessions. After combining groups, pregnant adolescents reported a significant shift in family formation and increased monetary support from partners from baseline to postpartum. Partner support is important for ensuring positive pregnancy outcomes. Additional strategies are needed to engage young fathers who do not readily provide support during pregnancy.
