在技术全会上,IAB（互联网体系结构委员会）讲述了他们在IP模型演进方面的工作。在他们的工作中,IP模型指由IP层向上层协议和应用程序暴露的服务模型（图1）。也就是说,IP模型可以看成一套被更上层依赖的行为,或者一套上层对IP的期望。从这种意义上说,它就像一个发展了很长时间的松散的约定。 相似文献

Emotional congruence with children is a psychological construct theoretically involved in the etiology and maintenance of sexual offending against children. Research conducted to date has not examined the relationship between emotional congruence with children and other psychological meaningful risk factors for sexual offending against children. The current study derived potential correlates of emotional congruence with children from the published literature and proposed three models of emotional congruence with children that contain relatively unique sets of correlates: the blockage, sexual deviance, and psychological immaturity models. Using Area under the Curve analysis, we assessed the relationship between emotional congruence with children and offense characteristics, victim demographics, and psychologically meaningful risk factors in a sample of incarcerated sexual offenders against children (n = 221). The sexual deviance model received the most support: emotional congruence with children was significantly associated with deviant sexual interests, sexual self-regulation problems, and cognition that condones and supports child molestation. The blockage model received partial support, and the immaturity model received the least support. Based on the results, we propose a set of further predictions regarding the relationships between emotional congruence with children and other psychologically meaningful risk factors to be examined in future research. 相似文献

This study focuses on learning in three different hypermedia environments that either support autonomous learning, learner-controlled learning or system-controlled learning and explores the mediating role of academic self-regulation style (ASRS; i.e. a macro level of motivation) on learning. This research was performed to gain more insight in the conditions under which learning in hypermedia environments is effective. Sixty-nine grade five students from a primary school answered short essay questions using video material from a hypermedia environment. The effects on task motivation and test performance were measured. It was found that learners in the autonomy supported hypermedia environment reported lower levels of controlled task motivation, compared to the learners in the system-controlled and learner-controlled hypermedia environments. But there were no effects of hypermedia environment on autonomous task motivation or the reported need fulfilment for autonomy. Furthermore, learners in the learner-controlled hypermedia environment scored lower on a delayed, In-Depth Knowledge Test compared to learners in the other two environments. Moreover, learners in the autonomy supported hypermedia environment watched more (unique) videos compared to learners in the system-controlled and the learner-controlled hypermedia environments. As for the role of learners' ASRS, we found no interaction with the type of hypermedia environment on task motivation or performance. Learners' ASRS did, however, affect the learners' motivation for the task. And, when presented with advice (as in the autonomy supported hypermedia environment) learners with an autonomous self-regulation style followed more advice, compared to learners with a more controlled self-regulation style. 相似文献

Near-infrared spectroscopy is currently used to assess changes in the oxygen saturation of the muscle during exercise. The primary purpose of this study was to assess the reliability of near-infrared spectroscopy in determining muscle oxygen saturation (StO2) in the vastus lateralis during cycling and the gastrocnemius during running for exercise intensities at lactate threshold and maximal effort. Test-retest reliability was determined from an intraclass correlation coefficient obtained from a one-way analysis of variance. Reliability of muscle StO2 for the gastrocnemius at lactate threshold was R = .87, and R = .88 at maximal effort. Reliability of muscle StO2 for the vastus lateralis at lactate threshold was R = .94 and R = .99 at maximal effort. 相似文献

ABSTRACTWhile some Canadian universities have a long history in the provision of data services, that was not the norm in Canada, especially in small universities and colleges. To maximize the use of data by students and researchers in academia, it was evident that increased education, resources, and tools were required to support those delivering data services on their campuses. To this end, the Data Liberation Initiative (DLI) Survival Guide was designed as a comprehensive reference tool, which complements an established regional training curriculum, whereby enabling librarians to effectively fulfill their role as a DLI Contact in their academic institutions. This case study will examine the history, current state, and recommended future direction of the Survival Guide. This article will also examine the challenges in understanding the drivers shaping academic service delivery and the ways in which the guide has evolved to remain current to the needs of the Canadian data community. 相似文献

In order to become expert readers of an alphabetical language like French, students must develop and adequately use phonological knowledge. Considering that the phonological knowledge used in reading largely comes from knowledge of the oral language, what happens when the oral language is not accessible, as is the case for many deaf children? In this study, graphophonemic and syllabic processes in pseudoword reading were assessed with a similarity judgment task. Gestual deaf subjects aged 10–18 years old (N = 24) were compared to 24 age-matched hearing subjects. The results show that deaf readers are less sensitive to the graphemic and the syllabic structures of pseudo-words than hearing readers. In deaf subjects, the results are different than chance-level in the 13–15 and the 16–18-year-old groups. These results indicate that gestual deaf readers can develop phonological knowledge even in settings where sign language is promoted. 相似文献

ABSTRACTThe last twenty years have seen an increased emphasis around the world on the quality and quantity of research in response to national research assessments, international league tables, and changes in government funding. The prevailing attitude in higher education embeds research as the ‘gold standard’ in the context of academic activity. However, a key feature of this trend is significant gender differences in research activity. We argue that research productivity is related to identification as a researcher, and that identifying as ‘research-active’ or not would appear to depend upon how an individual academic subjectively defines ‘research’. This article brings together two hitherto separate bodies of work (1) the impact of gender on academic research careers, and (2) academic conceptions of research. Through a combination of interviews, focus groups and questionnaires, we investigate the extent to which interpretations of ‘research’ and ‘research activity’ differ by gender within an institution in the UK and the potential impact of these interpretations. Although the research found that there are many similarities in the interpretations of ‘research activity’ between genders, we found one important difference between male and female participants’ conceptions of research and its relationship to teaching. Significantly, our findings suggest that there is a need to expand our existing conceptualisations of ‘research’ to include ‘research as scholarship’ in order to address the obstacles that current understandings of ‘research’ have placed on some academics. Self-definition as a researcher underlies research activity. A narrow conception of ‘research’ may prevent individuals from identifying as ‘research-active’ and therefore engaging with research. 相似文献

This study examines the development and implementation of a survey-based instrument assessing the effectiveness of a course redesign initiative focused on student centeredness at a large midwestern university in the United States. Given the scope of the reform initiative under investigation in this study, researchers developed an instrument called the Classroom Experience Questionnaire (CEQ), which was administered to students enrolled in redesigned courses. Early findings demonstrate strong construct validity and internal reliability of the CEQ instrument as well as concurrent validity between the CEQ and observation data gathered in concert with self-report data. The authors conclude that in the absence of trained classroom observers, the developed student self-report protocol can serve as a useful tool for measuring the constructivist orientation of pedagogy and student-centered nature of the learning environment in a higher education setting. 相似文献

Music, visual arts and design instruction has hardly been studied by the educational research community in Switzerland. Beyond a narrow group of specialists, there is little aware-ness of the basic pedagogical premises, subject matter expertise and the theoretical underpinnings of music visual art and design education although these areas of instruction are firmly anchored in the education goals for compulsory public schooling that have been outlined at national level in Switzerland and a generous amount of instructional time appears to be allocated to these subject areas in comparison with curriculum guidelines in other countries. This paper presents the findings of a trend analysis focused on music, visual arts and design instruction in Switzerland. It shows the importance accorded to aesthetic subjects within the scope of compulsory public education, explores differences in the amount of time resources allocated to these subject areas and describes the subject-specific and cross-functional goals and objectives. Teacher education programs are also examined as their current content and structure raise concerns about inadequate teacher qualifications that contradict the ambitious curricular goals. A review of previous research efforts, most of which have explored the transfer effects of creative, artistic subject areas, follows and desiderata with respect to the future development of research activities are presented. 相似文献
