The mid 1990s was a period when the development of the household market for new information and communication technologies (ICTs) was of paramount importance for producers and suppliers. The Household Information Systems project was devised to investigate whether or not discourses of convergence accompanying the development of new ICT services and products had any resonance in the lives of "ordinary" consumers. This article presents an overview of the research and a more general series of observations about research into the domestic consumption of new media technology. The article advocates an approach to studying new media technology that analyzes the "full life cycle" of technology. In practice, this means utilizing theories from a range of disciplines focusing on a number of different points in the "cultural circuit" within which all technology is located. 相似文献

The aim of this study was to determine the prevalence of sleep disorders in an elite rugby union team using in-laboratory polysomnography (PSG) and sleep questionnaires. Twenty-five elite rugby union players underwent a night of PSG during the “off-season” of the Super Rugby competition to assess their sleep. Of interest were measurements that detected the presence of obstructive sleep apnea (OSA; apnea-hypopnea index ≥5 events/hr) and the presence of moderate-severe periodic leg movements during sleep (PLMs; ≥15 events/hr). Players completed sleep-related questionnaires to assess daytime sleepiness, perception of insomnia, risk of OSA, and the presence of restless legs syndrome (RLS) and underwent basic anthropometric assessments including body mass index and neck circumference. OSA was present in 24% (n=6) of players and PLMs ≥15 events/hr in 12% (n=3). Questionnaire responses showed that all players had insomnia defined subthreshold insomnia and excessive daytime sleepiness, two players were identified as being at risk for OSA and none were classified as having RLS. In conclusion, sleep disorders and excessive sleepiness are common in elite rugby union players. A process to identify and manage sleep disorders should be considered by teams to optimise their physical recovery, athletic performance and to safeguard their health. 相似文献

The way we define learning and what we believe about the way learning occurs has important implications for situations in which we want to facilitate changes in what people know and/ or do. Learning theories provide instructional designers with verified instructional strategies and techniques for facilitating learning as well as a foundation for intelligent strategy selection. Yet many designers are operating under the constraints of a limited theoretical background. This paper is an attempt to familiarize designers with three relevant positions on learning (behavioral, cognitive, and constructivist) which provide structured foundations for planning and conducting instructional design activities. Each learning perspective is discussed in terms of its specific interpretation of the learning process and the resulting implications for instructional designers and educational practitioners. The information presented here provides the reader with a comparison of these three different viewpoints and illustrates how these differences might be translated into practical applications in instructional situations. 相似文献

Extending Pryzwansky's (1977) work on the Developmental Test of Visual Motor Integration (VMI), this paper investigated scoring agreement among three levels of increasingly better trained VMI diagnosticians. Correlational data demonstrated high interexaminer reliabilities (.92, .93, and .98) between groups of Consumers (Special Education undergraduates), Experts (doctoral Psychology students), and Consensus-Judges (experienced school psychologists) in their scoring of 39 subject protocols. However, gross errors in precision were discovered after the raw scores had been converted into the VMI age equivalent scores: fully 56% of the assigned age equivalent scores resulted in discrepancies of at least one year of age. These findings indicate that, despite high interexaminer reliabilities, great caution must be exercised when children are evaluated or placed by virtue of their age equivalent scores. 相似文献

A mixed-method approach was used to explore parent and child perspectives on death in Mexico. Parents’ and children’s death-related experiences and understanding of death were examined. While all children in this sample displayed a biological understanding of death, older children were less likely to endorse that all living things die. Children also displayed coexistence of beliefs related to death that can be attributed to both their biological and spiritual understanding of death. We also found that older children were more likely to report that a child should feel sad following the death of a loved one. These findings highlight how cultural practices shape the development of cognitive and affective processes related to death. 相似文献

The internal consistency reliability of the Boehm Test of Basic Concepts (BTBC) was examined for 40 Hispanic and 40 non Hispanic kindergarten pupils in the Southwest. Subscale and total scale reliabilities appeared to be comparable. This evidence supported the reliability of the BTBC for Hispanic and non Hispanic kindergarten pupils. 相似文献

By use of the multiple Laplace transform a partial differential equation and its associated boundary conditions characterizing a boundary value problem in n independent real variables can be transferred directly into an algebraic equation in n independent complex variables. This algebraic equation can be solved for the multiple transform of the solution of the boundary value problem. Multiple inversion of this transform then gives the desired solution. The general theory underlying such solution of boundary value problems in two and three independent variables is advanced in detail. Use of this theory is illustrated by solution of two specific problems. 相似文献

Being entered for exams and reaching key educational thresholds, for example 5 A* to C grades (including English and Mathematics) at GCSE, are important markers of participation and success in secondary education. However, little is known about the prevalence and make-up of children in care reaching these thresholds. Using secondary data analysis, we compared the proportions of children in care, children ‘in need’ and children in the general population who achieved four key thresholds, including exam entry and 5 A* to C grades, including English and Mathematics. We then focused on children in care and examined factors that predicted exam entry and achieving 5 A* to C grades, including English and Mathematics. Children receiving social care interventions were less likely than children in the general population to be entered for exams or to reach important educational thresholds. For children in care, several socio-demographic, care and educational factors predicted their likelihood of success. No children with an autistic spectrum disorder or who had ever been permanently excluded were recorded to have achieved 5 A* to C grades, including English and Mathematics. Children with poor attainment at Key Stage 2 were also at significant risk of not achieving this threshold. Practitioners and policymakers should consider the modifiable risk factors for poor educational performance and be aware of groups of children in care who are at significant risk of not achieving a minimum standard which could open doors for their future. 相似文献

Standardized, large-scale assessment of educational outcomes has become a global phenomenon over the past three decades (Smith, 2016 ). A key challenge facing assessment designers is that standard formats may be inaccessible or may create barriers to student performance. Schwanke, Smith, and Edyburn's ( 2001 ) A3 model describes how advocates have reacted to structural barriers by providing accommodations and, ultimately, accessibility. This paper synthesizes and evaluates three studies that attempted to improve accessibility in assessments for students who struggle with print reading through audio presentation of assessment items. Cross-study implications for policy and practice are considered. 相似文献
