The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models. 相似文献

Abstract The purpose of this article is to highlight key findings from a study of 24 early childhood preservice teachers as they moved away from a reliance on traditional interpretations of child‐centered curricula toward one of collaborative inquiry. Participants enrolled in a 15 week undergraduate teaching methods course were assigned to teaching teams to implement collaborative projects with the same group of 3–5‐year‐old children. The study utilized both quantitative and qualitative measures to assess conceptual level, changes in reflectivity, and inquiry‐oriented teaching. Results suggest that the emergence of collaborative inquiry among preservice teachers is a dynamic and diverse process not readily assessed by static measures or discreet skills. Collaborative projects did provide a context for creating communities of learners within which time, space and opportunity to practice, reflect and use language and other tools contributed to young teachers’ development of inquiry. 相似文献

ABSTRACT Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r2 = 0.31), object control (r2 = 0.19), and total motor score (r2 = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood. 相似文献

A survey conducted at three Florida library systems examines caregivers' perceptions of emergent literacy programming and how these perceptions compare with the National Research Council's features for quality programs for children. The survey results reveal that caregivers' perceptions of emergent literacy programming align with the National Research Council's features. The data demonstrates that caregivers' perceptions are very positive toward emergent literacy programming in terms of learning and the environment. Caregivers' perceptions of the environment answers were mostly strongly agree. These results were more positive than their perceptions of learning, although they strongly agree that these programs prepare children for school, reading, and social interaction. The survey results will inform public libraries as to how to design, market, and deliver emergent literacy programming to caregivers with very young children. 相似文献

Changes in the world of work as well as demographic shifts toward a more diverse college population and workforce require changes in the way career counseling is provided on college campuses. The authors propose using a narrative group counseling approach to serve college and university students from various cultural backgrounds. Through this approach, students develop their own career/life stories, incorporating their cultural values, family and community considerations, and life roles. 相似文献

“Countability not answerability?” Accountability in Hong Kong and Singapore universities 总被引:1,自引:1,他引:0
Singapore and Hong Kong are vying to be the principal educational hub for the Asia-Pacific region and have begun to compete with Australia, Britain, Canada and the USA in providing cross-border education. Although these four Anglo-American countries still dominate cross-border education, Singapore and Hong Kong hope to make inroads into this export market and compete on the global stage. To create “world-class” universities, Singapore and Hong Kong have introduced quality assurance mechanisms, diversified funding sources, and restructured their university governance systems. This article compares the accountability measures introduced into Hong Kong and Singapore universities, and the responses of academics and administrators to these measures. The results indicate that both countries introduced greater autonomy as they augmented accountability for their universities, and the term “decentralised centralism” describes the kind of government control exerted in these Asian universities in the twenty-first century. 相似文献
