The aim of this case study was to determine whether a sailor's deliberate choice of a conservative strategy to manage sleep deprivation would allow him to cross the Pacific Ocean and to minimize his state of anxiety and perceived fatigue. The participant, who had more than 10 years' sailing experience in severe conditions, was tested on a small catamaran without any living quarters during a solo Pacific Ocean crossing. Estimations of sleep hours, state anxiety, and perceived fatigue were self-reported by the sailor on a daily basis using a specific questionnaire. The most important finding is that the sailor's deliberate sleep strategy, 5.4 h sleep per day (24% less than on-shore), was enough to keep his anxiety and perceived fatigue within acceptable limits and enabled him to achieve his goal, which was the first crossing of the Pacific Ocean on a catamaran of less than 6 m. In conclusion, our results suggest that the sailor observed in the present case study was able to minimize anxiety and perceived fatigue with adequate sleep to optimize his performance, security, and to achieve his goal. 相似文献

Students with autism spectrum disorders (ASDs) are increasingly being educated within mainstream schools. While there is often an assumption that students with ASD who are academically capable will succeed in an inclusive educational placement, previous research has indicated that this is not always the case. Indeed, it seems that students with ASDs are often not equipped to cope with the social and communication demands of a mainstream classroom. Autism Spectrum Australia's (Aspect) satellite class programme aims to address this gap by blending specialised intervention with strategies to prepare students and receiving schools for transition to more inclusive educational placements. A long-term follow-up study comprising a parent survey of satellite class graduates and four detailed case studies was undertaken to determine whether these classes led to successful placement of students with ASD in more inclusive educational settings. Results indicated that a majority of graduates remained placed in more inclusive educational settings. Overall, parents were satisfied with the programme. Attendance at a satellite class was just one of a number of factors associated with positive outcomes in late adolescence. These findings are discussed in terms of their implications for teachers and school staff planning for and supporting students with ASDs in their transition to inclusive educational settings. 相似文献

Abstract Over the last two decades, there has been a significant change in the financing of higher education in the United States. A decrease in student and institutional support in real terms, tuition increases at all types of institutions, along with the view that students are the primary beneficiaries of higher education has resulted in policies that reduce the proportion of higher education costs borne by the federal and state governments. This paper will describe this financing shift in the United States, and analyse its impact on college participation with a particular focus on equity and opportunity. It will also provide an analysis of some questions that European countries should address as they implement their own policies that shift the burden of paying for college from the government to individuals, and as they consider various forms of financial assistance to help students pay for college. 相似文献

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

This paper is a critical review of some recent literature around the ‘literacies of the digital’ in schools and higher education. It discusses the question: ‘what does the conjoining of the terms “digital” and “literacy” add to our understanding of teaching and learning in higher education’? It explores the continuing role of critical literacy in relation to the idea that digital literacies are transformative for pedagogy in this sector. 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
