企业安全文化认同机理及其影响因素

为明晰企业安全文化认同机理,进而提升企业安全文化建设效率与质量,分析企业主流安全文化的形成过程,并构建企业安全文化认同机理模型。在此基础上,分别从个体认同、群体认同与组织认同3个层面,阐释企业安全文化认同机理,提取对企业安全文化认同有显著影响的12个关键因素,并指出促进企业安全文化认同应从这些关键影响因素着手。结果表明,企业主流安全文化是员工认同企业安全文化的基础,企业安全文化认同是企业主流安全文化向企业强势安全文化过渡的关键环节。

Subspace design of low-rank estimators for higher-order statistics

Higher-order statistics (HOS) are well known for their robustness to additive Gaussian noise and ability to preserve phase. HOS estimates, on the other hand, have been criticized for high complexity and the need for long data in order to maintain small variance. Since rank reduction offers a general principle for reduction of estimator variance and complexity, we consider the problem of designing low-rank estimators for HOS. We propose three methods for choosing the transformation matrix that reduces the mean-square error (MSE) associated with the low-rank HOS estimates. We also demonstrate the advantages of using low-rank third-order moment estimates for blind system estimation. Results indicate that the full rank MSE corresponding to some data length N can be attained by a low-rank estimator corresponding to a length significantly smaller than N.     

Chips,tags and scanners: Ethical challenges for radio frequency identification

Radio Frequency Identification (RFID) systems identify and track objects, animals and, in principle, people. The ability to gather information obtained by tracking consumer goods, government documents, monetary transactions and human beings raises a number of interesting and important privacy issues. Moreover, RFID systems pose an ensemble of other ethical challenges related to appropriate uses and users of such systems. This paper reviews a number of RFID applications with the intention of identifying the technology’s benefits and possible misuses. We offer an overview and discussion of the most important ethical issues concerning RFID, and describes and examine some methods of protecting privacy. Norman G. Einspruch serves as a consultant to several high-technology companies, one of which is in the RFID components and systems business.     

价值认同与大学生核心价值体系教育

社会主义核心价值体系是社会主义意识形态的本质体现。高等学校肩负着培养社会主义合格建设者和可靠接班人的重任,更迫切需要坚持用社会主义核心价值体系武装大学生,努力使他们成为社会主义核心价值体系的深入学习者、坚定信仰者、积极传播者和模范践行者。完成好这一历史性任务的关键环节就是要在把握大学生对社会主义核心价值体系认同特点的基础上,从认知认同、情感认同和行为认同三个方面来实现大学生对社会主义核心价值体系的认同,构建起大学生社会主义核心价值体系价值认同教育体系。     

Profiling teachers’ sense of professional identity

This study shows that professional identity should not be viewed as a composed variable with a uniform structure. Based on the literature and previous research, we view teachers’ job satisfaction, self‐efficacy, occupational commitment and change in the level of motivation as indicators of teachers’ professional identity. Using two‐step cluster analysis, three distinct professional identity profiles have empirically been identified, based on data of 1214 teachers working in secondary education in the Netherlands. These profiles differed significantly regarding the indicators of teachers’ professional identity. Teachers belonging to the found profiles did not significantly differ in their amount of experience.     

定向运动员反应认知方式特征的研究

通过对57名中国定向运动员（男30名,女27名）反应认知方式的测试与分析,发现定向运动员的反应认知方式主要为慢而准确型、快而不准确型和快而准确型,以慢而准确型为主。优秀与一般定向运动员反应认知方式特征的差异主要体现在准确性上,优秀运动员的准确性明显高于一般运动员。优秀定向运动员的反应认知方式主要为慢而准确型和快而准确型。定向运动可能具有要求运动员反应认知方式以准确为主要目标的特征。反应认知方式测试与评价可用于定向运动员的选材、个性化教学与训练。     

基于摄动法的裂纹梁振动模态研究

为评估裂纹损伤发生的位置及损伤程度,基于改进的裂纹损伤模型,应用摄动法研究裂纹梁的振动模态变化特性.建立由一阶和二阶摄动量表示的EulerBernoulli裂纹梁振动特征方程,推导出裂纹梁振动特征值和模态振型的一阶和二阶摄动解析表达式,并通过与损伤悬臂梁实验结果对比,验证该方法的可靠性.     

民国期刊的版本识别及其客观著录

民国期刊的版本信息在著录时作为次要款目容易被忽略或遗漏,影响了读者对文献的考证和研究。民国期刊版本信息具有客观著录的必要性,编目人员可根据民国期刊的外部特征、内部的文字记录和标记、民国期刊的权威工具书和研究资料来识别一些常见的版本,并利用现有的编目规则对民国期刊版本信息进行客观著录。     

基于规则的网络文本资源标题快速自动识别方法

选取网络文本资源的标题识别作为切入点,除考虑多数研究关注的文本的格式信息(如字体)、位置信息等特征外,加入对标题与网页正文内容的相关度的考虑,利用科技监测项目采集到的大量历史数据作为统计分析的基础,从候选标题的可能来源和特征方面,构建基于规则的网络文本资源标题快速识别方法,并给出该方法的时间效率和识别准确率测评结果。
