Given the relationships of item response theory (IRT) models to confirmatory factor analysis (CFA) models, IRT model misspecifications might be detectable through model fit indexes commonly used in categorical CFA. The purpose of this study is to investigate the sensitivity of weighted least squares with adjusted means and variance (WLSMV)-based root mean square error of approximation, comparative fit index, and Tucker–Lewis Index model fit indexes to IRT models that are misspecified due to local dependence (LD). It was found that WLSMV-based fit indexes have some functional relationships to parameter estimate bias in 2-parameter logistic models caused by violations of LD. Continued exploration into these functional relationships and development of LD-detection methods based on such relationships could hold much promise for providing IRT practitioners with global information on violations of local independence.  相似文献

The decade of the 1970s heralded a major research effort into mariculture of economically important red and brown seaweeds. Limited and declining natural populations, lack of synthetic substitutes for the phycocolloids, and their upwardly spiralling costs have emphasized the need for more research in this area. Algal mariculture is now technically and scientifically feasible, but the economic realities are still undetermined. This article examines what is known about seaweed mariculture and discusses where future research efforts must go.  相似文献

Findings are presented from a qualitative longitudinal collective case study of 29 teachers newly appointed to rural or remote schools in Western Australia. All participants experienced stress and articulated coping strategies in response: direct-action, palliative and avoidant strategies. Where protective structures and processes existed in environments, teachers employed direct-action problem-solving strategies. Avoidant strategies were more common in young and mature-aged novices, rather than experienced teachers.Three critical times were identified to support adaptation: first weeks of appointment for information, first semester for assistance, support, feedback for development of competence and three months before the year-end for stability and certainty.  相似文献

The aim of the study is to compare gender patterns of student attitudes toward school, teachers and peers in grade 6 over time. In 1967–68 and in 2003, 1500 pupils responded to the same 40‐item questionnaire. A confirmatory factor analysis was applied. In the gender comparison the within‐class level was used. The more traditional school factors, Interest in School, View of Teacher, and Work Atmosphere, showed no differences between the two time periods. The factor Interest in School showed that girls were more positive than boys. In contrast to this, changes with more positive attitudes had occurred especially in boys’ peer relational factors. In Relations with Classmates and in View of Fuss, the scores were now equal between the two genders, but in View of Peers, and Lack of Anxiety the boys’ attitudinal scores were significantly higher than those of the girls.  相似文献

This article employs a transnational feminist lens to examine the experiences of racialised immigrant girls who provide care for their younger siblings. The article draws on findings from a participatory action research study in Victoria, British Columbia, Canada to examine the role that immigrant girls’ caregiving practices play in transnational families’ social, economic, and cultural survival. It argues that greater attention should be given to the diverse and complex contexts, consequences, costs, and contributions of immigrant girls’ caregiving labour.  相似文献

A perturbation paradigm was employed to assess 3- and 6-month-old infants' and their mothers' sensitivity to a 3-s temporal delay implemented in an ongoing televised interaction. At both ages, the temporal delay affected infant but not maternal behavior and only when implementing the temporal delay in maternal (Experiment 1, N=64) but not infant (Experiment 2, N=60) behavior. In addition, the experimental manipulation influenced promptness of maternal smiling responses reliably more than promptness of infant smiling responses. The findings suggest that the timing of maternal behavior plays an important role in infants' perception of maternal responsiveness, whereas mothers seem to monitor general aspects of infant behavior such as overall level of engagement.  相似文献

There is widespread consensus in the research and policy‐related literature over the last decade that young people who have been permanently excluded from school are at a far greater risk of a variety of negative outcomes than young people who have not had this experience. These negative outcomes include prolonged periods out of education and/or employment; poor mental and physical health; involvement in crime; and homelessness. This article presents evidence from a small‐scale qualitative study of destinations and outcomes post‐exclusion for a group of young people considered to be at particular risk of such negative outcomes: namely, those who have been permanently excluded from special schools or Pupil Referral Units (now known as short‐stay schools). The specific focus of this paper is on the 24 young people's educational trajectories pre‐ and post‐exclusion; the reasons for their exclusion from school; and on what forms of alternative provision were available to them after their permanent exclusion.  相似文献

An Australian study of generic competencies required by engineers   总被引:1,自引:1,他引:0  
Engineering curricula have expanded in recent decades. In addition to science and technical engineering, they now include several non-technical competencies. This is a trend reinforced by programme accreditation. The authors take the viewpoint that it is important to ensure that graduates have the competencies they will require for their work. The following question is addressed: What are the generic competencies that engineers graduating in Australia require for their work as engineers?

Competencies were identified from a broad range of literature and then rated by 300 established engineers for importance to their jobs. The results indicated that non-technical, attitudinal and technical competencies were perceived to be important. Eleven competency factors were revealed empirically. Profiles of these competency factors among graduates would assist evaluation and improvement of engineering programmes. This is the first quantitative study conducted in Australia that encompassed all engineering disciplines and focused on established engineers rather than recent graduates.  相似文献

This paper explores the development of children’s centres in England between 2004 and 2008, focusing on the newly created centres that have been located on primary and nursery school sites. Using both an analysis of policy documents and interview data from three urban local authorities, we examine the use of premises and the differing priorities of centre staff and school heads, particularly in relation to the balance of services between early years education, childcare and family support. We also explore governance issues, focusing especially on patterns of accountability. In so doing, we also examine the tensions that exist between children’s centres located on primary and on nursery school sites and the schools themselves.  相似文献
