Impact of Gender and the Stereotyped Nature of Illustrations on Choice of Color: Replica of the Study by Karniol (2011) in a Spanish Sample

Early acquisition of stereotypes that associate “blue” with boys and “pink” with girls can influence their preferences for these colors and also their choices in clothing, toys or objects in relation to gender stereotypes. In a Spanish sample (5–10-year olds, n = 614), this study reproduces the previous research conducted by Karniol (Sex Roles 65(1/2):119–132, 2011) for the purpose of analyzing whether gender-linked color preferences rule the choice of coloring booklets and if children’s choices of color are affected by their own gender. The results show that although boys used fewer female-stereotyped colors than girls, both genders colored in each figure with the stereotyped colors associated with them. This result indicates that boys and girls share similar gender stereotypes and use colors that agree with these stereotypes.     

On the Properties of the SAVE Directions

In quadratic discriminant analysis, the use of SAVE (Cook and Weisberg, 1991 Cook, R.D., Weisberg, S. (1991). Discussion of Li (1991). J. Amer. Statist. Assoc. 86:328–32.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]; Pardoe et al., 2007 Pardoe, I., Yin, X., Cook, R. (2007). Graphical tools for quadratic discriminant analysis. Technometrics 49:172–183.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) is often recommended for dimension-reduction purposes. However, the associated directions tend to over-emphasize the differences of the groups in dispersion, ignoring at the same time those in location. This behavior makes often the plots of the corresponding canonical coordinates difficult to interpret. In this article, the properties of SAVE are investigated and related to those of the SIR and SIRII components. Applications with real data are presented. Comparisons with previous work in this area are also discussed.     

Changes in Economic Hardship and Intimate Partner Violence: A Family Stress Framework

While recent studies underscore how financial stress and lack of tangible assets significantly increase the odds of intimate partner violence (IPV) among couples, little is known about these effects over time. Theoretically informed by family stress theory, this study examines the influence of changing subjective reports of economic hardship over time on the risk for IPV. Specifically, we test two hypotheses: (1) change in economic hardship significantly predicts IPV; and, specifically, (2) increased economic hardship or unstable economic conditions increases the risk of IPV. Using longitudinal data from the Fragile Families and Child Well-being Study, we assess the incidence of IPV for 941 women in committed relationships. Results from our logistic regression analyses suggest that after controlling for numerous demographic factors, women who never experienced economic hardship had lower odds of experiencing IPV than those who did. Further, women who experienced high levels of economic hardship over time had the highest odds of experiencing IPV. However, the effects of changing economic hardship on IPV were attenuated once maternal depression and parenting stress were controlled. Results are discussed in terms of practice and policy implications.     

Mental Health Among Mexican-Origin Immigrant Families: The Roles of Cumulative Sociodemographic Risk and Immigrant-Related Stress

The current study examined the unique effects of cumulative sociodemographic risk and immigrant-related stress on mental health symptoms among Mexican-origin immigrant parents and their school-age children. Further, this study tested whether the effects of cumulative sociodemographic risk and immigrant-related stress on child mental health were mediated by parent mental health. Participants included 104 Mexican-origin immigrant families. Families in the study had a child between the ages of 6 and 10 (M_age = 8.39; 61% female). Data were collected across three time points spaced 6 months apart. Immigrant-related stress was found to predict parent mental health, which in turn predicted child mental health. Cumulative sociodemographic risk did not predict parent or child mental health. Mental health symptoms generally decreased over time, but for children, change in mental health symptoms depended on parent mental health symptoms. Given the high levels of mental health symptoms among Mexican-origin parents and children, reducing a context of stress and promoting mental health interventions for Mexican-origin immigrants is critical.     

Audience Response Systems: Using “Clickers” to Enhance BSW Education

Among new technologies for enhancing classroom-based education are audience response systems (ARS), also known as “clickers.” These handheld devices record student responses to instructor questions and send them electronically to a receiver that tallies the responses. Summary results are then projected, usually as a graph. Instructors piloted the use of clickers in undergraduate social work research and practice courses. Instructor and student experiences with the clickers were examined by type of course, frequency of use, ease of use, perceived impact on learning, and use by students with disabilities. Instructors and students in both types of courses found the clickers beneficial. Minor differences by type of course were found. Some students with disabilities noted problems using the clickers. More use of clickers and research on their use in social work education is recommended along with continued attention to universal design in course preparation.     

Combinatorial Voting

We study elections that simultaneously decide multiple issues, where voters have independent private values over bundles of issues. The innovation is in considering nonseparable preferences, where issues may be complements or substitutes. Voters face a political exposure problem: the optimal vote for a particular issue will depend on the resolution of the other issues. Moreover, the probabilities that the other issues will pass should be conditioned on being pivotal. We prove that equilibrium exists when distributions over values have full support or when issues are complements. We then study large elections with two issues. There exists a nonempty open set of distributions where the probability of either issue passing fails to converge to either 1 or 0 for all limit equilibria. Thus, the outcomes of large elections are not generically predictable with independent private values, despite the fact that there is no aggregate uncertainty regarding fundamentals. While the Condorcet winner is not necessarily the outcome of a multi‐issue election, we provide sufficient conditions that guarantee the implementation of the Condorcet winner.

Intergenerational and program-induced effects of welfare dependency: Evidence from the national longitudinal survey of youth

This study uses data from the National Longitudinal Survey of Youth to examine intergenerational and program-induced effects of welfare dependency. Three research questions are asked: (a) How do parental Aid to Families with Dependent Children (AFDC) receipt and other family background characteristics affect subsequent dependency on AFDC? (b) How do attitudes about welfare and state AFDC benefit levels affect AFDC dependency? and (c) How do the patterns and factors associated with AFDC dependency vary across racial and ethnic lines? The results suggest that women who grew up in households that received welfare during the woman's adolescence are approximately twice as likely to be dependent on AFDC in young adulthood as women whose families did not received welfare. Further, state AFDC benefit levels are associated with higher risks of AFDC dependency, but the association is significant only for Anglo women. These analyses provide little support for the hypothesis that attitudes toward welfare and low-wage work increase the likelihood of welfare dependency.     

Supply Chains and Global Health: An Imperative for Bringing Operations Management Scholarship into Action

Many people in developing countries do not have access to effective vaccines, medicines, and other life‐saving health technologies. Shortage of health care workers, severe financial constraints, and lack of awareness are some of the major obstacles that prevent higher access. However, ineffective and poorly designed supply chains for purchasing and distributing the medicines, vaccines, and health technologies are one of the most important barriers to increasing access. We argue that the ineffectiveness of the global health supply chain can be attributed largely to: coordination problems across multiple stakeholders with widely divergent objectives, lack of careful supply chain design, and use of myopic operational objectives and metrics. The operations management research community can contribute to improving this by applying existing knowledge to the field of global health delivery and by researching new frameworks of analysis which would then become the cornerstones for policy advice to those who design, operate, or finance these supply chains.
