Fred outdoors: An initial report into the experiences of outdoor activities for an adult who is congenitally deafblind

Abstract

Outdoor Education has long been used with groups that could be described as having “special needs”. Research in this particular area has in the past concentrated on adaptations to equipment and activities, allowing access for people with physical disabilities, and expanding the learning and development opportunities available to those with learning difficulties. This article documents the initial observations made of the experiences of a man, who is congenitally deafblind, when given the opportunity to experience outdoor activities. The article highlights a number of areas, which appear particularly relevant to this specific target group, and may be worthy of further investigation. The use of video technology is also demonstrated to be a valuable research tool when working with people who have multisensory impairments.     

同步录音录像制度的功能、问题与期待

同步录音录像具有规范侦查取证、保障公民权利、证明取证合法以及增强办案能力的制度功能,但新刑事诉讼法中有关同步录音录像的规定比较笼统,实践中选择性录音录像成最大难题。现阶段有必要鼓励对所有刑事案件进行录音录像、对“全程录制”进行严格界定与执行,同时规范同步录音录像的相关操作程序,并在实践中探索同步录音录像实施的制度性保障。     

Reconsidering the use of video clubs for student-teachers' learning during field placement: Lessons drawn from a longitudinal multiple case study

Although video clubs have been used to support (student) teachers' learning through reflection upon practice, less attention has been paid to their potential use for supporting changes in participants' practice over a period of time. Prior work has also largely treated (student) teachers as an undifferentiated whole that benefits in similar ways from video clubs. In this study, we problematize this assumption by drawing on three cases of student teachers to exemplify three different learning paths while participating in a video club during field placement. Reflecting on these findings, we discuss implications for differentiating the video-club approach to address different student teachers.

Triggering effects of mobile video marketing in nature tourism: Media richness perspective

The aim of this study was to investigate videos as potential triggers of behavior. Therefore, we applied the theories of triggers and media richness to learn about the triggering efficiency of mobile marketing videos on participants’ behavioral intentions. The experiment involved three distinct test groups, each comprising 41 student participants. From the perspective of media richness theory, we observed that the different kinds of videos had quite similar effects in terms of triggering behavioral changes. However, the mechanisms explaining why triggers were present differed for each video. Further, the results reveal that the consumer's position in the information search process was the most significant reason for the triggering of any kind of effect. In addition, the instructionally designed videos were able to exert an affective triggering effect: the more participants liked the video, the more it affected their participation intention and recall scores. This study extends the media richness research by demonstrating that the effects of media richness can vary within technically similar videos, as they form different logical connections among non-verbal visual cues related to a video's storyline.     

Affordances of using Multiple Videoed Events to construct a rich understanding of adult–child book readings

This paper explores the affordances of using video-based research to capture a multiplicity of events, along with multimodal representations when producing data related to adult–child book readings. In doing this we answer two questions: (1) why more than one event is needed when seeking a comprehensive collection of information for the purpose of analysis; and (2) why one mode of data production alone (e.g. audio recordings or note taking) is insufficient to record practice or interviews when richness is of priority. This research used three videoed events to produce data. These included videoing: (1) caregiver–child interactions during four shared book reading sessions, (2) interviews with caregivers immediately following each of the reading sessions and (3) video-stimulated discussions with caregivers within two months of the final shared book reading. In this paper, I contribute to discussions that highlight the affordances of using video-based research as a means of capturing the multimodal elements of an experience, which can contribute to the analysis and interpretation of data. I expand on this, however, to suggest that when coupled with a multiplicity of events, video-based research can be a means of pursuing richness via a method that has been criticized for its narrow subjectivity.     

Using video to promote early childhood teachers' thinking and reflection

This article examines findings from a qualitative study employing group stimulated-recall interviews using video-recordings of early childhood teachers to elicit their thinking and reflections about their teaching interactions. It focuses on the value of video to enable teachers to reflect on their practices and the extent to which collectively viewing recorded episodes allows negotiated understandings of their own and other teachers' practices. Whilst these findings suggest that video and collective dialogue are useful professional learning tools for teachers to examine and improve their teaching, structural and relational challenges exist that may impact on how effectively such tools are used.

A parallel memory architecture for video coding

To efficiently exploit the performance of single instruction multiple data （SIMD） architectures for video coding, a parallel memory architecture with power-of-two memory modules is proposed. It employs two novel skewing schemes to provide conflict-free access to adjacent elements （8-bit and 16-bit data types） or with power-of-two intervals in both horizontal and vertical directions, which were not possible in previous parallel memory architectures. Area consumptions and delay estimations are given respectively with 4, 8 and 16 memory modules. Under a 0.18-pm CMOS technology, the synthesis results show that the proposed system can achieve 230 MHz clock frequency with 16 memory modules at the cost of 19k gates when read and write latencies are 3 and 2 clock cycles, respectively. We implement the proposed parallel memory architecture on a video signal processor （VSP）. The results show that VSP enhanced with the proposed architecture achieves 1.28× speedups for H.264 real-time decoding.
