Racial Group Membership and Multicultural Training: Examining the Experiences of Counseling and Counseling Psychology Students

This study documents various process elements of multicultural training from the perspective of counseling and counseling psychology students within the United States (US). Using a mixed-methods approach, findings indicate that racial group membership is an important variable that differentially impacts White students and students of Color while undertaking a multicultural counseling course. Results of a principal components analysis revealed four components associated with racial group membership, including negative racial experiences and salience of racial diversity. Findings from a grounded theory analysis identified five overarching themes including intense emotional experiences, representing one’s racial group, and issues of safety impacting course experience. Implications for training and future research are offered.     

Empowering infants through responsive and intentional play activities

This qualitative case study explored how an infant teacher provided meaningful learning experiences for infants through play and the teacher’s educational rationale behind these experiences. Findings were based on multiple sources of data, including classroom observations (natural observation and videotaped observation) for approximately 12 weeks and a teacher interview. The findings confirmed that infant play is critical for infant learning and development and portrayed the process through which the infant teacher created play spaces for infants and supported infants’ play through both pre-planned, teacher-directed, intentional activities, and child-initiated, emerging play activities. Our study highlighted that the designing of infant play and the learning process needs to be flexible and based on careful observation and reflection in order to meet the rapidly changing needs and interests of a group of infants as well as individual infants.     

Success at Scale: Outcomes of Community-Based Neurodevelopment Intervention (CASITA) for Children Ages 6–20 months With Risk of Delay in Lima,Peru

This study is a randomized controlled trial of a 12-week community-based group parenting intervention (“CASITA”) in Lima, Peru. CASITA improved neurodevelopment in a pilot study of 60 Peruvian children and subsequently scaled to 3,000 households throughout the district. The objective of this study was to assess intervention effectiveness when implemented at scale. A total of 347 children ages 6–20 months (52.7% male, 100% identified as “mestizo”) at risk for developmental difficulties were randomized to immediate or delayed CASITA. At 3 months after enrollment, the immediate arm showed significantly higher overall development, based on the Extended Ages and Stages Questionnaire and Home Observation for Measurement of the Environment scores (Cohen’s ds = .36 and .31, respectively). Programs demonstrably effective at scale could help address children’s development risks worldwide.     

Growth of Social Competence During the Preschool Years: A 3‐Year Longitudinal Study

This study examined the stability and growth over a 3‐year period of individual differences in preschool children's social competence, which was assessed in three domains: social engagement/motivation, profiles of behavior and personality attributes characteristic of socially competent young children, and peer acceptance. A total of 255 children (126 girls and 129 boys) participated in this study. Growth curve analyses demonstrated both stability and change with regard to social competence over early childhood. Social competence measures and latent variables were invariant over this time period, individual differences in social competence were largely stable from year to year, and significant increases over time were observed for the domain most closely reflective of specific personal attributes skills.     

Migration distance-based platelet function analysis in a microfluidic system

Aggregation and adhesion of platelets to the vascular wall are shear-dependent processes that play critical roles in hemostasis and thrombosis at vascular injury sites. In this study, we designed a simple and rapid assay of platelet aggregation and adhesion in a microfluidic system. A shearing mechanism using a rotating stirrer provided adjustable shear rate and shearing time and induced platelet activation. When sheared blood was driven through the microchannel under vacuum pressure, shear-activated platelets adhered to a collagen-coated surface, causing blood flow to significantly slow and eventually stop. To measure platelet adhesion and aggregation, the migration distance (MD) of blood through the microchannel was monitored. As the microstirrer speed increased, MD initially decreased exponentially but then increased beyond a critical rpm. For platelet-excluded blood samples, there were no changes in MD with increasing stirrer speed. These findings imply that the stirrer provided sufficiently high shear to activate platelets and that blood MD is a potentially valuable index for measuring the shear-dependence of platelet activation. Our microfluidic system is quick and simple, while providing a precise assay to measure the effects of shear on platelet aggregation and adhesion.     

Translation of ‘America’ during the early Cold War period: a comparative study on the history of popular music in South Korea and Taiwan

Abstract

The evaluation of the cold war influences played by the US on the rest of the world should not only be accounted economically and politically, but also culturally. In this paper we see the US influences on South Korea and Taiwan from the value‐laden concept of Americanization and through which we examine comparatively specific practices of domestic popular music development in these two countries. Setting this paper as a historical comparative study, we see the working of Americanization in relation to popular music as a value regime in which American is constructed as an ideal model imaginatively and discursively, which was made possible by economic, social and cultural forces in South Korea and Taiwan. Focusing on the Cold War period, circa 1950s to 1960s, levels and aspects of Americanization were therefore ways of translation, to use Said’s concept of traveling theory analogically; Anglo‐American music genres traveled to these countries to be incorporated contextually as new or trendy conventions of music‐making, which in turn helped form local music genres. The socio‐historical contexts of South Korea and Taiwan, with respect to the presence of American army forces, and similar postwar anti‐communist political forces, in nation‐building (north–south Korea, red China–free China antagonism respectively) are central to our understanding of the visibility of Americanization in different music cultures in these two countries. This paper will go into each country’s historical trajectory of music practices that took Japanese colonial influences up to the postwar time and then blending with Anglo‐American genres in indigenizing that eventually marked their different paths, as we comparatively reveal their institutional, political and national cultural conditions, which were necessary in shaping each country’s music‐making conventions, entertainment business, and consumption cultures of popular music – and that might implicitly inform tentatively the present rivalry between ‘offensive’ Korean Wave and ‘defensive’ Taiwanese ‘rockers’ in the globalization era.     

Reading-growth estimates for elementary-school students using curriculum-based measurement

In this study, we examine grade-level growth rates for general education students and students with learning disabilities in grades two to six. In conducting the study, we demonstrate how schools, districts, and state educational agencies can use a combination of Curriculum-Based Measurement and Hierarchical Linear Modeling (HLM) methods to develop growth-rate norms in reading. The participants were made up of 273 general education students and 430 students with learning disabilities. The growth rates for these two groups of students in each grade were estimated using HLM. Within each grade, separate growth rates for subgroups of general education students (i.e., high, average, and low achievers) were estimated. The uses of estimated growth rates for setting year-end goals, monitoring student progress, and evaluating the effectiveness of instructional programs are also discussed.
