Electric charge-mediated coalescence of water droplets for biochemical microreactors

This work proposes the use of charged droplets driven by the Coulombic force as solution-phase reaction chambers for biological microreactions. A droplet can be charged near an electrode under dc voltage by direct contact to the electrode. This process is called electrical charging of droplet (ECOD). This charged droplet can then be transported rapidly between electrodes following the arc of an electric field line by exploiting electrostatic force. As on-demand electrocoalescence, both alkalization of phenolphthalein and bioluminescence reaction of luciferase in the presence of adenosine triphosphate are studied to test the feasibility of the biochemical microreactors using ECOD. Two oppositely charged droplets are merged to have a color change immediately after microchemical reaction. The applicability of an ECOD-driven droplet to measurement of glucose concentration is also tested. The glucose concentration is measured using a colorimetric enzyme-kinetic method based on Trinder’s reaction [J. Clin. Pathol. 22, 158 (1969)]. The color change in the merged droplet is detected with an absorbance measurement system consisting of a photodiode and a light emitting diode.     

Hierarchical Models of Social Competence in Preschool Children: A Multisite,Multinational Study

The generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5‐group, multinational sample (N = 1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first‐order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within‐sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children.     

Engaging young children in collective curriculum design

In this study we investigate how 5-year-old children in Brazil and their teachers collectively design science curriculum. More specifically, we develop an agency|structure dialectic as a framework to describe this collective praxis in which science curriculum may emerge as the result of children–teacher transactions rather than as a result of being predetermined and controlled by the latter. We draw on a cultural-historical approach and on the theory of structure and agency to analyze the events showing the complexity of the activity inside a classroom of very young children by science education standards. Data were collected in the context of a science unit in an early-childhood education program in Belo Horizonte. Our study suggests that (a) throughout the movement of agency|passivity || schema|resources one can observe participative thinking, a form of collective consciousness that arises in and from lived experience; (b) learning is a process in which a group is invested in searching for solutions while they create schemas and rearrange resources to evolve a new structure; and (c) the emergent curriculum is a powerful form of praxis that develops children’s participation from early childhood on.     

Paulo Freire,Critical Literacy,and Indigenous Resistance

Using several case studies drawn from Freire’s cultural context and contemporary Canadian Indigenous resistance movements, this article questions whether a Freirean approach to critical literacy can work with Indigenous literacy needs without reproducing colonial power structures. It also seeks to examine current scholarship in the literacy education of Maritime Aboriginal people in Canada and to illustrate the need for critical pedagogies honoring multiple cultural literacies and ways of knowing among Indigenous youth.     

Negotiating Cross-cultural Misunderstandings in Collaborative Therapeutic Conversations

In this article we discuss how clients who have immigrated to Canada and Canadian counsellors negotiate cross-cultural misunderstandings as opportunities to transcend reified assumptions about cultures. Cultural differences as well as discrepancies in translation need to be worked out for counsellors and clients to arrive at shared understandings useful for clients. Arriving at shared understandings requires conversational partners to recognize and overcome how cultural differences may influence personal interpretation of each other’s actions. Misunderstandings, in this sense, highlight affiliative or disaffiliative choices to speakers. We suggest that counsellors can benefit from inviting clients’ initiatives and preferences to inform how relationships develop.     

Assessment of the quality and generalizability of the revised UCLA loneliness scale in Chinese and Korean community-dwelling elderly populations using item response theory (IRT)-Rasch modeling and hybrid IRT-logistic regression

ABSTRACT

Objectives: This study aims to test the dimensionality, reliability, and item quality of the revised UCLA loneliness scale as well as to investigate the differential item functioning (DIF) of the three dimensions of the revised UCLA loneliness scale in community-dwelling Chinese and Korean elderly individuals.

Method: Data from 493 elderly individuals (287 Chinese and 206 Korean) were used to examine the revised UCLA loneliness scale. The Research model based on item response theory (IRT) was used to test dimensionality, reliability, and item fit. The hybrid ordinal logistic regression-IRT test was used to evaluate DIF.

Results: Item separation reliability, person reliability, and Cronbach’s alpha met the benchmarks. The quality of the items in the three-dimension model met the benchmark. Eight items were detected as significant DIF items (at α < .01). The loneliness level of Chinese elderly individuals was significantly higher than that of Koreans in Dimensions 1 and 2, while Korean elderly participants showed significantly higher loneliness levels than Chinese participants in Dimension 3. Several collected demographic characteristics and loneliness levels were more highly correlated in Korean elderly individuals than in Chinese elderly individuals.

Conclusion: Analysis using the three dimensions is reasonable for the revised UCLA loneliness scale. Good item quality and the items of this measure suggest that the revised UCLA loneliness can be used to assess the preferred latent traits. Finally, the differences between the levels of loneliness in Chinese and Korean elderly individuals are associated with the factors of loneliness.
