Developmental Precursors of Relational Aggression From Late Childhood Through Adolescence     

Alazne Aizpitarte  Olivia E. Atherton  Lucy R. Zheng  Itziar Alonso-Arbiol  Richard W. Robins 《Child development》2019,90(1):117-126

Relational aggression—a psychological form of aggression—has numerous negative consequences for physical and emotional health. However, little is known about the risk factors that lead youth to engage in relational aggression. Using multimethod data from a longitudinal research of 674 Mexican-origin youth, this study examined the influence of parents, siblings, and peers on the development of relational aggression. Increases in relational aggression from age 10 to 16 were associated with: (a) low levels of parental monitoring and (b) increased association with deviant peers and siblings. These results held across gender and nativity status. The findings suggest that multiple socialization agents contribute to the development of relational aggression. We discuss the practical implications for reducing relational aggression during adolescence.  相似文献

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow     

Jeonghun Nam  Justin Kok Soon Tan  Bee Luan Khoo  Bumseok Namgung  Hwa Liang Leo  Chwee Teck Lim  Sangho Kim 《Biomicrofluidics》2015,9(6)

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.  相似文献   

Voice over distance: a case of podcasting for learning in online teacher education     

Dianne Forbes  Elaine Khoo 《Distance Education》2015,36(3):335-350

This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal.  相似文献   

Assessing and developing critical-thinking skills in higher education     

Dirk Van Damme  Doris Zahner  Olivia Cortellini  Teresa Dawber  Kelly Rotholz 《European Journal of Education》2023,58(3):369-386

Generic skills such as critical thinking, problem solving, and communication are essential for students' success in higher education and their careers. This article presents findings from an international study of students' (n ≈ 120,000) generic skills from six countries using a performance-based assessment. Results indicate that higher education students, on average, gain generic skills between entry and exit. However, learning gain is less marked than could be expected and varies significantly among country samples. Various background variables such as gender, ethnicity, parental level of education, and primary language are also explored. The authors conclude that it is feasible to reliably and validly measure generic skills in a cross-cultural context and that assessment of these skills is an essential component of best practices in higher education.  相似文献   

Age Differences in Choice Deferrals as Functions of Interattribute Conflict and Decision Domain     

Olivia L. Pethtel 《Educational gerontology》2013,39(10):772-782

The primary purpose of the present study was to examine age differences in choice deferral when young and older adults make high vs. low conflict decisions in two domains (i.e., health and commodity). Sixty young and 60 older adults were presented with four different decision scenarios in which they could either choose an option or use choice deferral (i.e., not choose any of the options for the time being). The high conflict decisions had negative interattribute correlations, while the low conflict decisions had positive interattribute correlations. Older adults were more likely than young adults to choose the deferral option across domains. Participants were more likely to choose the deferral option when making high conflict decisions than when making low conflict decisions. For older adults, an increase in postdecision positive affect was greater for those who deferred choice than for those who did not defer choice in the commodity domain. Implications were discussed in terms of real-life decision making of older adults.  相似文献   

The Relationship Between Psychopathology and Shame in Secondary School Students     

Rebecca P. Ang  Angeline Khoo 《Pastoral Care in Education》2004,22(1):25-33

This study investigated the relationship between psychopathology and shame. Three hundred and thirty-one Secondary 2 students from Singapore participated in the study. All students completed a self-report questionnaire consisting of the Anxiety and Depression scales of the Behavior Assessment System for Children (BASC), the short version of the Aggression Questionnaire (AQ), and the Internalized Shame Scale (ISS). As predicted, students in the comorbid group at-risk for anxiety, depression and aggression, had significantly higher shame scores compared with at-risk students in all the other three single-disordered groups (anxiety-only, depression-only, or aggression-only) as well as students in the control group. Also, as expected, the control group scored significantly lower compared to all other single-disorder groups and the comorbid group. Implications of these findings with regard to comorbidity of psychopathology and its relationship to shame, classroom interventions, as well as implications pertaining to teachers' and counsellors' work with at-risk students will be discussed.  相似文献   

The Smithsonian Folklife Festival and Cultural Heritage Policy in Colombia: A Case Study     

Olivia Cadaval  Cristina Diaz‐Carrera 《Curator: The Museum Journal》2014,57(4):423-436

As Colombia began to develop its Intangible Cultural Heritage (ICH) policy, it signed an agreement with the Smithsonian Center for Folklife and Cultural Heritage to collaborate on a Smithsonian Folklife Festival of Colombia's national living traditions, to be shown on the National Mall in 2011. This essay addresses the role of the Smithsonian Folklife Center in advocating for a cultural heritage policy grounded in cultural democracy and intercultural dialogue, as well as its collaboration with UNESCO in crafting the 2003 convention for the protection of intangible cultural heritage. We focus on the Center's signature collaborative program, the Smithsonian Folklife Festival, and on our experience with the 2011 Festival program, Colombia: The Nature of Culture. We examine the relationship between the Festival and Colombia's intangible cultural heritage communities, policies, and practices, through intercultural dialogues that contribute to shaping Intangible Cultural Heritage policy from the bottom up.  相似文献   

Diaspora as method: Inter-Asia Cultural Studies and the Asian Australian Studies Research Network     

Olivia Khoo 《Inter-Asia Cultural Studies》2019,20(2):290-301

ABSTRACT

What is the place of the diasporas within the Inter-Asia Cultural Studies movement, and how can Asian diasporas in the West contribute to Inter-Asia's intellectual project of “problematising Asia”? Developing a notion of diaspora as method, this essay highlights the complementary relationship between the Asian Australian Studies Research Network and the Inter-Asia Cultural Studies network. It argues that the Inter-Asia network has much to gain from embracing the Asian Australian diaspora as an interlocutor with shared priorities and concerns, and that Asian Australian studies can also productively learn from Inter-Asia's alternative model of institutionalisation, thereby expanding its theoretical and methodological frames of reference.  相似文献
