P2P技术在校园网络的应用研究     

马立军  覃纪武 《文教资料》2006,(10):162-163

Peer-to-Peer(P2P)网络被喻为第三代网络,采用的是点对点分散式网络架,它不需要服务器的中转,使用户与用户之间的连接更加方便、快捷,更大范围地实现资源共享。本文首先分析了目前校园网络的体系结构的存在的资源共享瓶颈,通过P2P技术与传统的校园网络构架的对比,在分析P2P技术的关键技术与优势的基础上提出在校园网络引入P2P技术的重要性与可行性。  相似文献

语言测试理论与大学英语测试     

张迎春  王小潞 《湖州师范学院学报》2007,29(4):95-98

依据Bachman和Palmer的语言测试原则,对浙江大学英语专业学生和非英语专业学生同时进行两份试卷测试。测试结果表明:CET和TEM无论对英语专业学生和非英语专业学生而言都具有区分度;非英语专业的学生并不绝对地比英语专业学生英语能力差。这两套试卷测试相关度很高,表明用统一的考试机制更能客观地反映各类学生的英语实际水平。  相似文献

Orienting Schools Toward Equity: Subgroup Accountability Pressure and School-Level Responses     

Rachel Garver 《The Educational forum》2017,81(2):160-174

Abstract

This article examines school-level responses to subgroup accountability pressure through an ethnographic case study of a school cited for failing to make adequate yearly progress for student subgroups. Concerns about the calculations and measures used to derive the citation and reservations about acting on accountability data delegitimized the citation and rendered the identified subgroups irrelevant to daily practice. Under district guidance, compliance with subgroup accountability was independent of the school's internal efforts to promote equity.  相似文献

Matters of Form: Questions of Race,Identity, Design,and the U.S. Census     

Deborah Balzhiser  Charise Pimentel  Amanda Scott 《Technical Communication Quarterly》2019,28(1):3-20

This case examines how functionalist approaches manifest culturally based on users’ contexts. The authors conduct a critical visual semiotic analysis of the race and Hispanic origin questions on the 2010 U.S. Census form, demonstrating how incongruities in design potentially harm people. This demonstrates a need for adding critical analyses to design and research and it refocuses the Society for Technical Communication’s value of promoting the public good on to design and documentation in order to fight injustice.  相似文献   

Political and educational springboard or straitjacket? Theorising post/human subjects in an age of vulnerability     

Kathryn Ecclestone  Daniel Goodley 《Discourse: Studies in the Cultural Politics of Education》2016,37(2):175-188

Contemporary discourses of social justice in education, disability, mental health, social policy and feminist studies are refracted increasingly through concerns about psychological and structural vulnerabilities created by the crises of late capitalism. Focusing on developments in British social policy generally and educational research specifically, this paper uses the authors' contrasting perspectives on two discernible discourses of vulnerability emerging in these contexts. One elevates the recognition of collective vulnerability as a springboard for new conceptualisations of resistance that disrupt materialist narratives of the human subject as a coherent, unified and rational agent of history. A second discourse offers a materialist understanding that locates vulnerability as both driver and product of a ‘therapeutic culture’, arguing that a psycho-emotional focus for vulnerability offers a diminished and ineffective subjectivity that belies rhetorics of resistance. These contrasting perspectives generate and emerge simultaneously from new understandings of the human subject. The paper evaluates the implications of using vulnerability to frame expectations of human subjects for everyday educational practices and relationships. It concludes by suggesting empirical questions that need exploring.  相似文献
