Discrimination and Ethnic-Racial Socialization Among Youth Adopted From South Korea Into White American Families

The current study examined how discrimination relates to adjustment outcomes in a sample of internationally, transracially adopted Korean Americans from the Minnesota Sibling Interaction and Behavior Study (N = 456 adoptees; M_age at T1 = 14.9, M_age at T2 = 18.3, M_age at T3 = 22.3). The moderating roles of ethnic socialization and preparation for bias by parents (i.e., ethnic-racial socialization) were also examined. Results indicated that discrimination predicted higher levels of depressive and externalizing symptoms in youth who reported less preparation for bias. In those experiencing more preparation for bias, associations were not significantly different from zero. Ethnic socialization did not moderate these associations. Such findings provide important information for adoptive parents regarding how to prepare their children to cope with discrimination.     

The war of the words: The rhetoric of ‘Operation Iraqi Freedom’ (an informal survey)

The political, military and media rhetoric of the March–April 2003 invasion of Iraq is interpreted as a phenomenon of power in relation to an understanding of culture as a site of denegation. Patterns of tautology, euphemism and equivocation are identified and their rhetorical appeal analysed in terms of the denegational structure of each of these figures. The essay is thus governed by an understanding of figuration as instrumental, not ornamental; it shows how rhetoric can be studied as a cultural phenomenon and argues by example that a pragmatics of troping is crucial to such a study.

Darwin’s Difficulties and Students’ Struggles with Trait Loss: Cognitive-Historical Parallelisms in Evolutionary Explanation

Although historical changes in scientific ideas sometimes display striking similarities with students’ conceptual progressions, some scholars have cautioned that such similarities lack meaningful commonalities. In the history of evolution, while Darwin and his contemporaries often used natural selection to explain evolutionary trait gain or increase, they struggled to use it to convincingly account for cases of trait loss or decrease. This study examines Darwin’s evolutionary writings about trait gain and loss in the Origin of Species (On the origin of species by means of natural selection, or the preservation of favoured races in the struggle for life. D. Appleton, New York, 1859) and compares them to written evolutionary explanations for trait gain and loss in a large (n > 500), cross-cultural and cross-sectional sample (novices and experts from the USA and Korea). Findings indicate that significantly more students and experts applied natural selection to cases of trait gain, but like Darwin and his contemporaries, they more often applied ‘use and disuse’ and ‘inheritance of acquired characteristics’ to episodes of trait loss. Although the parallelism between Darwin’s difficulties and students’ struggles with trait loss are striking, significant differences also characterize explanatory model structure. Overall, however, students and scientists struggles to explain trait loss—which is a very common phenomenon in the history of life—appear to transcend time, place, and level of biological expertise. The significance of these findings for evolution education are discussed; in particular, the situated nature of biological reasoning, and the important role that the history of science can play in understanding cognitive constraints on science learning.     

Racial/ethnic differences in Medicaid expenditures on psychotropic medications among maltreated children

This study quantifies racial/ethnic differences in Medicaid expenditures on psychotropic drugs among a national sample of children with suspected maltreatment. We linked 4,445 child participants in the National Survey of Child and Adolescent Well-Being (NSCAW) – consisting of children investigated for suspected abuse and neglect – to their Medicaid claims obtained from 36 states. We used propensity score matching to construct a comparison group of children without known child welfare involvement, and estimated two-part generalized linear models to examine differences in annual psychotropic drug expenditures per child between children of different races/ethnicities. When compared to a matched sample of children, African American and Latino children incur $292 and $144 less expenditures on psychotropic drugs, respectively, than white children. Among NSCAW children alone, African American children display $614 less spending on psychotropic drugs when compared to white children. Racial/ethnic differences in expenditures on psychotropic drugs occur among all children on Medicaid, but the differences are especially pronounced among African American children in contact with the child welfare system. These findings demonstrate that policymakers will need to pay special attention to the needs of children of color as Medicaid expansions proceed nationwide.
