Adaptive progressive download based on the MPEG-4 file format

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the "moov" box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Re1-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved.

1919-1922年土耳其人民的民族解放斗争

土耳其是在伟大的十月社会主义革命的影响之下,首先掀起民族解放运动的国家之一.十月革命中诞生的苏维埃国家,引起了土耳其人民群众的深刻同情.苏联政府放弃了对土耳其领土的一切侵害,放弃了沙皇政府在不平等条约(特权条约制度)的基础上所获得的损害土耳其人民利益的经济和法律的权益.苏联政府公布了沙皇俄国同英、法、意关于瓜分土耳其的密约,揭穿了协约国的侵略计划.     

开明教育

强制性教育在大自然这一方面是没有疑问的,大自然很早以前就为我们制定了这一法规。然而,像所有强制性法规一样,自然的法规既无情又带有盲目性。无知和明知故犯会得到同样坏的下场,无能和犯罪也会遭到同样的惩罚。大自然甚至不需先斩后奏,而是斩而不奏,你只能自己去琢磨为什么被打了耳光。我们通常所说的教育(即有人类参与的教育,因此我叫它人工教育),目的就是弥补大自然教育的不足,就是让孩子在接受大自然教育之前做必要的准备,消除他的无能与无知,教他不去明知故犯,让他学会识别大自然喜怒哀乐的前兆,避免被打耳光。简言之,一切人为的教育…     

Inclusive instruction and learning for deaf students in postsecondary education

This article explores how students who are deaf and their instructors experience mainstream college classes. Both quantitative and qualitative procedures were used to examine student access to information and their sense of belonging and engagement in learning. Instructors were asked to discuss their approach to teaching and any instructional modifications made to address the needs of deaf learners. Results indicate that deaf students viewed classroom communication and engagement in a similar manner as their hearing peers. Deaf students were more concerned about the pace of instruction and did not feel as much a part of the 'university family' as did their hearing peers. Faculty generally indicated that they made few if any modifications for deaf students and saw support service faculty as responsible for the success or failure of these students. We discuss results of these and additional findings with regard to barriers to equal access and strategies for overcoming these barriers.

On the importance of motivation in Munchausen by Proxy: the case of Kathy Bush

The recent trial and conviction of Kathy Bush for abusing her daughter is used to illustrate (1) the nature of the motivation, in at least some cases of MBP, and (2) the importance of distinguishing the motivation found in MBP from that found in other forms of child abuse and other conditions involving factitious illness production.
