论文化强国视角下的图书馆文化使命

文化是指人类在社会历史发展过程中所创造的物质财富和精神财富的总和,是一个民族的血脉和灵魂,是国家发展、民族振兴的重要支撑.图书馆本质即是一种文化的存在,又是一种社会文化机构.通过从文化视角探析图书馆文化的内涵,阐述图书馆在文化强国视角下,承担的文化使命及提高为文化强国建设服务的着力点.     

论人的历史性存在方式——基于《1857-1858年经济学手稿》物化社会关系的一种理解

在前资本主义社会,人与共同体的关系表现为一种自然的依赖性。随着这种依赖性关系的解体,人的存在方式呈现为二重性。这种二重性构成资本主义物化社会关系的主要特征。物化的社会关系是资本主义社会存在、运行和发展的基础。由于资本本性的驱动和历史使命的内在要求,人类社会最终会扬弃物化的社会关系,克服直接的"自然必然性"的束缚,实现人的全面自由个性。     

弘扬和培养大学生的民族精神

民族精神是一个民族赖以生存和发展的精神支柱。当代大学生必须弘扬“民魂”精神 ,增强民族凝聚意识、民族使命感、责任感 ,“励精图治”勇于创新 ,才能以高昂的士气、饱满的政治热情 ,投身于伟大的社会主义建设事业之中 ,才能不断地推动我们中华民族走向现代化 ,才能让中国永远自立于世界民族之林 ,为人类的进步不断做出新的贡献。     

论大学在建设社会主义核心价值体系中的使命

社会主义核心价值体系为统一广大人民群众的价值观提供了强大的理论和实践支撑，在建设社会主义核心价值体系中，大学要担负起传播、践行、创新和发展社会主义核心价值体系的历史使命。     

有感于哈佛第28任校长就任

哈佛大学第28任校长朱尔·福斯特于2007年2月11日上任了.她是哈佛历史上第一任女性校长,然而,这不是重要的.她已时年59岁;她是一位历史学家;她任职前只是哈佛之下最小的一个学院的院长;她是经由选举产生的;她的前27任校长的平均任期近14年;……这些倒是可以引起我们思考的.     

差信道环境下简单有效的图像传输方法

The constrained Viterbi algorithm (C-VA) makes use of some prior reliable information to reduce complexity andimprove performance of Viterbi algorithm (VA). However it can only be used in the concatenate code scheme because thedetection result of cyclic redundancy check code (CRC) is exploited to provide reliable information. In this paper, a differentway is proposed to provide reliable information for C-VA, which is possible to be used in simple codec. Known bits were addedto the set partitioning in hierarchical trees (SPIHT) coded image sequence periodically and directly. They were thought to bereliable information for C-VA in the decoder. Experimental results show that the proposed scheme can obtain much bettererror resilient ability compared with conventional VA under the extremely inferior channel condition if the best desired qualityof reconstructed images can be sacrificed.     

Software vulnerability due to practical drift

The proliferation of information and communication technologies (ICTs) into all aspects of life poses unique ethical challenges as our modern societies become increasingly dependent on the flawless operation of these technologies. As we increasingly entrust our privacy, our well-being and our lives to an ever greater number of computers we need to look more closely at the risks and ethical implications of these developments. By emphasising the vulnerability of software and the practice of professional software developers, we want to make clear the ethical aspects of producing potentially flawed software. This paper outlines some of the vulnerabilities associated with software systems and identifies a number of social and organisational factors affecting software developers and contributing to these vulnerabilities. Scott A. Snook’s theory of practical drift is used as the basis for our analysis. We show that this theory, originally developed to explain the failure of a military organisation, can be used to understand how professional software developers “drift away” from procedures and processes designed to ensure quality and prevent software vulnerability. Based on interviews with software developers in two Norwegian companies we identify two areas where social factors compel software developers to drift away from a global set of rules constituting software development processes and methods. Issues of pleasure and control and difference in mental models contribute to an uncoupling from established practices designed to guarantee the reliability of software and thus diminish its vulnerability.     

高压静电除尘实验研究

研究了静电电压对除尘效率的影响，实验证明，在其他条件不变的情况下，除尘效率与电压呈正相关（R2=0．9753），随着电压的增加，有效驱进速度也增加，说明可以通过控制电压来控制除尘效率，达到最优化的工况条件，最大除尘效率η为99．4％。     

浅析殖民主义的双重使命

马克思认为殖民主义具有双重使命 :一个是破坏性使命 ;一个是建设性使命。马克思的殖民主义双重使命说是我们分析评价殖民主义的理论基础 ,起着指导我们全面、辩证地认识殖民主义客观历史的作用。
