A prerequisite to anti-racist socialization in families is acknowledging ethnic-racial (power) differences, also known as color-consciousness. In a sample of 138 White Dutch families from the urban Western region of the Netherlands with children aged 6–10 years (53% girls), observations and questionnaires on maternal color-consciousness and measures of children's attitudes toward Black and Middle-Eastern ethnic-racial outgroups were collected in 2018–2019. Variable-centered analyses showed that maternal color-conscious socialization practices were related to less negative child outgroup attitudes only. Person-centered analysis revealed a cluster of families with higher maternal color-consciousness and less prejudiced child attitudes, and a cluster with the opposite pattern. The mixed results emphasize the importance of multiple methods and approaches in advancing scholarship on anti-racism in the family context.  相似文献

Digital body preservation: Technique and applications     

Vicky Vandenbossche  Joris Van de Velde  Stind Avet  Wouter Willaert  Stian Soltvedt  Noeska Smit  Emmanuel Audenaert 《Anatomical sciences education》2022,15(4):731-744

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.  相似文献   

Teachers of learners with ASD in mainstream schools and classrooms in Spain: attitudes towards inclusive education     

Yolanda Muñoz Martínez  Cecilia Simón Rueda  Mª José de Dios Pérez 《British Journal of Special Education》2023,50(1):104-126

This study analyses the attitudes of teachers in Spain towards the inclusion of learners with autism spectrum disorder in mainstream education settings and their relationship with the perceived benefits of inclusion. The ex post facto prospective design included 180 teachers from 14 schools. Data were collected using a questionnaire on teachers' attitudes towards inclusive education and a second questionnaire on the benefits of inclusion developed for the specific purposes of this study. The results show teachers' positive attitudes towards inclusion as well as the benefits perceived. This study demonstrates the fundamental role of teachers' previous experience. Implications for inclusive cultures and practices in schools are discussed.  相似文献   

Instructional practices in secondary science: How teachers achieve local and standards-based success     

Beth A. Covitt  Elizabeth Xeng de los Santos  Qinyun Lin  Christie Morrison Thomas  Charles W. Anderson 《科学教学研究杂志》2024,61(1):170-202

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献   

Multinational subsidiary knowledge protection—Do mandates and clusters matter?     

Wolfgang Sofka  Edlira Shehu  Pedro de Faria 《Research Policy》2014

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of academic and management debate. However, most studies treat MNC subsidiaries as relatively passive actors. We challenge this assumption by investigating the drivers of knowledge protection intensity of MNC subsidiaries. We argue that knowledge protection intensity is determined by MNC subsidiary mandates and by opportunities and risks originating from the host region. We hypothesize that not just competence-creating but also competence-exploiting mandates increase knowledge protection intensity. In addition, technological cluster regions in the host country can be expected to provide opportunities for knowledge sourcing and MNC subsidiaries may be willing to protect knowledge less intensively to participate in cluster networks. We test our hypotheses using a dataset of 694 observations of 631 MNC subsidiaries in Germany and develop recommendations for research, managers and policy makers.  相似文献   

Freelancers and the absorption of external knowledge: practical implications and theoretical contributions     

Arjan?KozicaEmail author  Ulrike?Bonss  Stephan?Kaiser 《知识管理研究与实践》2014,12(4):421-431

The term absorptive capacity (AC) describes the process of utilising external knowledge. Although firms are becoming increasingly reliant on highly skilled freelancers as a source of external knowledge, the literature on AC has not incorporated this collaboration for freelancers. In this paper, we address this research deficit in two ways: First, we argue that the ability to collaborate effectively and efficiently with freelancers plays a crucial role in the process of absorbing external knowledge. Second, we argue that the example of freelancers challenges researchers to rethink the conceptualisation of organisational boundaries within the concept of AC. Our paper is based upon previous theoretical insights and exploratory empirical data from a research project on German IT freelancers. For the practice of knowledge management, our paper elaborates upon how organisations can enhance their AC by investing in practices and routines that contribute to successful collaboration with freelancers.  相似文献   

Brazilian soccer: symbolic dimensions of its practice     

Luiz Henrique de Toledo 《Soccer & Society》2014,15(1):48-64

This essay explores the symbolic dimensions of soccer in Brazilian society from the perspective of sports anthropology. It discusses how the founding of the game was handled, in terms of stylization and standardization of rules. This, as the essay argues, would effect amplified representations in emotional regimes and adhesion to the game, thus making it a singular sports modality for understanding societies such as Brazil.  相似文献   

Growth influences biomechanical profile of talented swimmers during the summer break     

Marc F. Moreira  Jorge E. Morais  Daniel A. Marinho  António J. Silva  Tiago M. Barbosa 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(1):62-74

This study aimed to analyse the effect of growth during a summer break on biomechanical profile of talented swimmers. Twenty-five young swimmers (12 boys and 13 girls) undertook several anthropometric and biomechanical tests at the end of the 2011–2012 season (pre-test) and 10 weeks later at the beginning of the 2012–2013 season (post-test). Height, arm span, hand surface area, and foot surface area were collected as anthropometric parameters, while stroke frequency, stroke length, stroke index, propelling efficiency, active drag, and active drag coefficient were considered as biomechanical variables. The mean swimming velocity during an all-out 25 m front crawl effort was used as the performance outcome. After the 10-week break, the swimmers were taller with an increased arm span, hand, and foot areas. Increases in stroke length, stroke index, propelling efficiency, and performance were also observed. Conversely, the stroke frequency, active drag, and drag coefficient remained unchanged. When controlling the effect of growth, no significant variation was determined on the biomechanical variables. The performance presented high associations with biomechanical and anthropometric parameters at pre-test and post-test, respectively. The results show that young talented swimmers still present biomechanical improvements after a 10-week break, which are mainly explained by their normal growth.  相似文献
