Transnational Crimes Against Culture: Looting at Archaeological Sites and the “Grey” Market in Antiquities

Abstract: Diversified transnational criminal activities coupled with broader geographic capabilities have turned the black and white line between the licit “upperworld” and the illicit underworld a murky sha...

Antidepressants augment natural killer cell activity: in vivo and in vitro.

Abstract: Depressed mood has been associated with reduced natural killer cell activity (NKCA). Further, amelioration of depressive symptoms by pharmacotherapy has resulted in augmented NKCA. Serotonin, an indoleamine implicated in the pathophysiology of affective disorders, enhances NKCA in vitro and lymphocytes possess serotonin transporters and receptors. The present study evaluated NKCA in depressed outpatients before and during treatment with the selective serotonin reuptake inhibitor (SSRI) fluoxetine (Prozac®). Further, the SSRIs, fluoxetine and paroxetine (Paxil®), were also incubated in vitro with lymphoid cells to evaluate possible direct effects of SSRIs on NKCA. Depressed outpatients were administered fluoxetine (20 mg/day) for 4 weeks. NKCA and severity of depression were evaluated at weeks 0, 1, 2, and 4. Serum concentrations of fluoxetine and norfluoxetine were obtained as well. Mononuclear cells obtained from nonpatient volunteers were incubated with pharmacologic concentrations of fluoxetine or paroxetine and NKCA measured with a standard chromium release assay. Fluoxetine treatment resulted in decreased symptoms of depression and increased serum concentrations of fluoxetine and norfluoxetine. Further, fluoxetine treatment was associated with augmented NKCA in a subgroup of depressed outpatients exhibiting low NKCA at baseline. Fluoxetine had no effect on NKCA in depressed individuals exhibiting high NKCA at baseline. Incubation of mononuclear cells with fluoxetine and paroxetine augmented NKCA in vitro. The enhancing effects of antidepressants on NKCA in vivo and in vitro indicate a possible direct drug interaction with lymphoid cells during pharmacotherapy, suggesting that pharmacologic treatment of depression may result in enhanced immune competence as indexed by enhanced NKCA and that NKCA could be pharmacologically augmented with antidepressants in individuals with compromised immune function.

Teaching with Technology: May You Live in Interesting Times

Abstract: During the past 10 years, teaching with computer technology, such as e-mail and the Web, has become customary throughout undergraduate economic education. The authors review the literature on the implications for student learning, present specific educational activities that use a number of different computer technologies, and discuss growing problems, such as "cyber-plagiarism," along with suggesting potential solutions. The future of using technology for teaching economics will be the continuation of recent trends: increased portability in the access to instruction and increased opportunities for interaction, including students' interaction with the material and with the instructor and other students.

Imageability and age of acquisition effects in disyllabic word recognition

Abstract: Imageability and age of acquisition (AoA) effects, as well as key interactions between these variables and frequency and consistency, were examined via multiple regression analyses for 1,936 disyllabic words, using reaction time and accuracy measures from the English Lexicon Project Both imageability and AoA accounted for unique variance in lexical decision and naming reaction time performance In addition, across both tasks, AoA and imageability effects were larger for low-frequency words than high-frequency words, and imageability effects were larger for later acquired than earlier acquired words In reading aloud, consistency effects in reaction time were larger for later acquired words than earlier acquired words, but consistency did not interact with imageability in the reaction time analysis These results provide further evidence that multisyllabic word recognition is similar to monosyllabic word recognition and indicate that AoA and imageability are valid predictors of word recognition performance In addition, the results indicate that meaning exerts a larger influence in the reading aloud of multisyllabic words than monosyllabic words Finally, parallel-distributed-processing approaches provide a useful theoretical framework to explain the main effects and interactions

Interethnic Ideology, Intergroup Perceptions, and Cultural Orientation

Abstract: We examined endorsement of multicultural, assimilation, and colorblind ideologies, including their relations to stereotyping and in-group bias, among community samples of Latinos and non-Latino Whites. Participants also completed measures of their orientations to Latino and non-Latino White cultures. Analyses indicated that participants endorsed multiculturalism more strongly than colorblindness and colorblindness more strongly than assimilation. Although Latinos endorsed multiculturalism more strongly than did Whites, ratings of colorblindness and assimilation did not differ. Both groups exhibited in-group bias and out-group homogeneity. However, multiculturalism was associated with lower in-group bias. Further, Latinos who more strongly endorsed multiculturalism perceived less within group variability (i.e., had stronger stereotypes), whereas the reverse was true for Whites. Finally, analyses of cultural orientation measures indicated that ethnicity is not synonymous with cultural orientation; Latinos were equally oriented to Latino and White cultures, overall, and Latino and White American orientations were unrelated.
