信息迷雾:国家战略竞争中不可忽视的重要对象

[目的/意义]在大国竞争日渐激烈的非常时期信息迷雾日益凸显,明晰和破除信息迷雾、防止战略误判是一项紧迫而严峻的情报工作。[方法/过程]文章通过阐述信息迷雾的由来,明确信息迷雾是国家战略竞争中不可忽视的重要对象,以美国对华及其他国家所实施信息迷雾和成本欺诈的案例,进一步分析其制造信息迷雾的意图及能够得逞的原因。[结果/结论]分析发现,受施国对施加国所形成的路径依赖、规则依赖和对抗依赖是信息迷雾始作俑者达成目的的重要原因。如要防范和破除信息迷雾造成的消极影响,就必须立足国家利益、树立底线思维、掌控真实情况,要以事物对象的自身规律为参照,增加成本视角的思考,审慎看待西方的话语和术语概念,对信息迷雾的发起方进行全面细致的情报工作,正确进行战略判断。

How accurate are gender detection tools in predicting the gender for Chinese names? A study with 20,000 given names in Pinyin format

Objective:We recently showed that the gender detection tools NamSor, Gender API, and Wiki-Gendersort accurately predicted the gender of individuals with Western given names. Here, we aimed to evaluate the performance of these tools with Chinese given names in Pinyin format.Methods:We constructed two datasets for the purpose of the study. File #1 was created by randomly drawing 20,000 names from a gender-labeled database of 52,414 Chinese given names in Pinyin format. File #2, which contained 9,077 names, was created by removing from File #1 all unisex names that we were able to identify (i.e., those that were listed in the database as both male and female names). We recorded for both files the number of correct classifications (correct gender assigned to a name), misclassifications (wrong gender assigned to a name), and nonclassifications (no gender assigned). We then calculated the proportion of misclassifications and nonclassifications (errorCoded).Results:For File #1, errorCoded was 53% for NamSor, 65% for Gender API, and 90% for Wiki-Gendersort. For File #2, errorCoded was 43% for NamSor, 66% for Gender API, and 94% for Wiki-Gendersort.Conclusion:We found that all three gender detection tools inaccurately predicted the gender of individuals with Chinese given names in Pinyin format and therefore should not be used in this population.     

Historicising teachers’ learning: a case study of productive professional practice

This paper reveals the significant historical traces which informed the learning practices of teachers at one particular school site in a rural and regional educational district in Australia. Drawing upon recent theorising into professional practice, the paper argues that teacher learning practices are intrinsically ‘ecologically’ related to teachers’ practices at specific sites. However, extending beyond this theorising, the research also reveals how teacher learning – in the case presented, in relation to classroom dialogue – is also significantly influenced by earlier learning experiences of the teachers involved. In this way, teachers’ practices are revealed as not only influenced by present-day, site-specific, whole-school teacher learning, but also by particular events encountered by teachers at an earlier phase of their careers. The research argues for a conception of teachers’ learning which is not only site-informed and ecologically arranged, but also deeply temporally embedded.

基于磁钉技术的集装箱码头AGV 定位精度分析

为解决自动导引车（Automated Guided Vehicle, AGV）的定位精度问题,以国内某在建的自动化集装箱码头为工程背景,研究与基于磁钉技术的AGV定位误差相关的因素.通过给出AGV惯性导航系统的运动方程和误差方程,按照工程实况,在忽略陀螺仪影响的基础上,得到AGV惯性导航系统位置误差的理论计算式.依此指出,基于磁钉技术的AGV组合导航系统定位精度与加速度计精度、AGV 运行方向的余弦、磁钉数据更新时间的平方成正比例关系.最后,对某工程算例进行数值仿真,验证了理论分析的正确性.该方法对磁钉排布、惯性导航系统传感器选型等有参考意义.

足坛"黑哨"刑法定性探析

归纳我国刑法学界对足坛"黑哨"刑法定性的3种代表性意见,即无罪论;公司、企业人员受贿罪说;受贿罪说。对"黑哨"进行刑法分析,认为:基于中国足协的特殊地位,由其指派的裁判员属于国家工作人员,从"黑哨"的行为特征看,完全符合受贿罪的构成要件,应当由司法机关介入对其犯罪行为进行刑法规制,充分发挥刑法的惩治、威慑作用,以便有效地治理"黑哨"现象。     

跳远运动员助跑速度感知能力训练对踏板准确性影响的实验研究

通过问卷调查和实验法对跳远运动员助跑踏板准确性和影响跳远运动员助跑速度感知能力的主要因素进行理论与逻辑分析,根据跳远专项特点优选出9种训练方法,实验组采用优选训练手段,对照组采用常用普通训练手段。在严格控制训练过程及训练条件下,进行为期16周的速度感知能力的训练,保证两组只在训练内容方面不同外,其余方面保持一致。实验后对实验组和对照组再次进行踏板准确性和跳远成绩的测定,结果表明:实验后实验组与对照组的跳远成绩与踏板准确性具有明显的差异性。
