1.Introduction
The reproduction systems of 3D images without using eyeglasses and other special accessories has always attracted attention and aroused great interest of developers and consumers of such equipment because of totally accurate image and method of its presentation.Such systems can be used and are already partially used in advertising,television,different devices (i.e.smartphones,tablet computers),at the exhibitions,etc.,as well as in various technical applications,training systems,simulators,etc. 相似文献

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h?1 wearing a backpack of either 0 (LC0), 10 (LC10), 15 (LC15) or 20?kg (LC20). Inspiratory (PImax) and expiratory (PEmax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean PImax and PEmax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?.05) with changes not different between trials (p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters. 相似文献

Tarrant County College’s Achieving the Dream transformation has not only changed the college but all who engaged in the initiative. In four years, through ATD TCC became a college with one purpose, one goal, and one focus—student success through data informed decision making. From TCC Chancellor Dr. Erma Johnson Hadley to campus administrators, faculty, and staff, the college embraced the call for systemic change and fully engaged in the step by step process. Personnel throughout the college reported widespread satisfaction with senior leadership and viewed collaborations with colleagues across the district as beneficial and personally rewarding. Tireless endeavors to wholly engage stakeholders, build a culture of evidence, and employ effective student success interventions through ATD not only transformed TCC but ushered the college onto the national stage with Leader College recognition. The college’s next steps include keeping that momentum going and building on what it has accomplished. 相似文献

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage. 相似文献

Superhero play is a specialised form of fantasy play with considerable appeal to young children. During superhero play, children have opportunities to pretend and often to play different types of roles within a safe and caring environment. When guided appropriately in an early childhood classroom, superhero play gives young children opportunities to gain a sense of mastery and empowerment as well as developmentally appropriate benefits by improving language skills, problem-solving and cooperation with peers. By recognising and modelling the characteristics of resiliency and promoting kindness with peers during superhero play, teachers can encourage children to be kind and resilient heroes to classroom friends. As today’s classrooms increasingly include diverse members, it is important for young children to understand and appreciate the peers they play and learn with at school. The result may be a richer learning experience and may break down barriers that can produce unfairness, bullying and aggressive behaviours. This article explores the essence of superhero fantasy play along with its benefits for young children. In addition, the article examines the challenge of superhero play in classrooms for early childhood educators by exploring teachers’ roles in play. A new pedagogy for supporting superhero play is introduced, addressing spiritual and educational concerns by suggesting ways in which teachers can increase resiliency, encourage new friendships and build classroom community among peers during play and classroom activities. 相似文献

To adequately monitor progress in writing, a test must show stability and demonstrate a performance profile over time that parallels those of accepted criterion measures. This study investigated the technical adequacy of seven objective indexes of writing quality in monitoring the progress of 36 middle school (Grades 6-8) students with mild disabilities over a 6-month period. The stability of each index was assessed. Holistic ratings of the same writing samples and the Test of Written Language served as validation criteria. Three indexes were moderately correlated with holistic ratings, but were not sufficiently stable over time. Direct, objective writing assessment must be used with caution for progress monitoring, given our present lack of precision in measuring the complex task of writing. 相似文献

Extracting policy-relevant information from large national surveys of educational achievement is ordinarily a nontrivial task. It is made more treacherous when the data are expressed on scales that are not uniquely determined. The paper begins with a critical analysis of a recent attempt to interpret the findings on reading achievement obtained by the National Assessment of Educational Progress (NAEP). It then describes a new approach to the quantification and interpretation of change and demonstrates its appropriateness for repeated cross-sectional designs such as NAEP. Limitations imposed by the survey design and the nature of the measurements are highlighted 相似文献
