浅析英语冗余现象的修辞学和语用学依据

冗余信息是言语交际过程中信息差的表现之一，它同语言的经济原则相对立，又会反作用于正常的信息传输，简短，精练，准确等修辞学原则和语用学会话合作原则中的若干准则，都是针对冗余提出的。但是从语义内容与语言形式的矛盾和语言规律来看，不应该片面地排除英语中的冗余现象，而是要深入地研究和充分地利用冗余规律，具体而言，就是依据修辞学分析语言性语境的冗余现象，依据语用学分析非语言性语境的冗余现象。     

Learning About Posterior Probability: Do Diagrams and Elaborative Interrogation Help?

To learn from a text, students must make meaningful connections among related ideas in that text. This study examined the effectiveness of two methods of improving connections—elaborative interrogation and diagrams—in written lessons about posterior probability. Undergraduate students (N = 198) read a lesson in one of three questioning conditions (read twice, embedded questioning, and elaborative interrogation) and one of three diagram conditions (text only, diagram without redundant text, and diagram with redundant text). Elaborative interrogation negatively affected learning from the lesson, relative to reading the lesson twice. One possible explanation for this finding is that the quality of answers to the elaborative interrogations was poor. When the lesson was read twice, diagrams helped learning from the lesson relative to text only. Implications of these findings for instruction in probabilistic reasoning are discussed.     

基于Cortex-A8的以太网通信冗余设计

基于网络通信的冗余需求,提出一种三网口以太网通信设计方案。方案采用Cortex-A8内核的AM3352芯片,利用芯片两个以太网控制器及GPMC扩展DM9000A实现3个以太网通信功能端口,为提升GPMC的总线优势,设计一种掉电存储解决方案。软件部分对冗余机制网络通信状态提出两种监控模式,使冗余通信状态得到及时反馈。实验证明,该设计可满足以太网冗余功能的需求。     

Parents’ attitudes towards students with a background of migration—Does the background of migration matter?

As linguistic heterogeneity in classrooms is rising constantly, it was shown that attitudes play a role in the inclusion of students with migrant backgrounds. This paper focuses on attitudes of parents towards students with a migrant background and how variables such as parents’ level of education, cultural differences, and their own background of migration shape their attitudes. To this end, data from 876 parents (486 mothers and 390 fathers) was assessed, and it was found out that parents with a migrant background displayed more positive attitudes towards the inclusion of students with a background of migration in contrast to parents without a migrant background. Moreover, fathers displayed more positive attitudes towards students with lower cultural differences compared to students with higher cultural differences. Furthermore, mothers with a higher level of education had more positive attitudes towards students with a migrant background compared to mothers with a lower level of education.

Workforce diversity in Kenyan public universities: an analysis of workforce representativeness and heterogeneity by employee gender and ethnic group

Workforce diversity is considered an indicator of successful diversity and equal employment opportunity initiatives. In Kenya, it is a legal requirement for all public establishments to seek to represent the diversity of the population in employment of staff. This study analyses ethnic and gender representativeness and heterogeneity of the workforce in public universities. The results show over-representation of certain ethnic groups and non-compliance with diversity requirements in most universities. Variations between universities with regard to workforce heterogeneity are not statistically significant. However, the link between workforce heterogeneity and degree of urbanisation of university location is statistically significant. The conclusion is that compliance with legal requirements does not necessarily translate into representativeness and heterogeneity of the workforce. A shift from legal compliance to planned increase in numbers of under-represented gender and ethnic groups through diversity initiatives that identify and address barriers to equal employment and discriminatory employment practices is recommended.

高管团队异质性、管理自主权与企业创新绩效--基于沪深A股上市公司的实证研究

既有研究虽然关注了高管团队异质性对企业创新绩效的影响,但却忽视了管理自主权对两者关系的调节效应。基于高层梯队理论,运用2014—2019年沪深A股537家上市公司的数据,实证研究了高管团队异质性对企业创新绩效的影响,并检验了管理自主权的调节效应。研究结果表明:高管团队年龄异质性对企业创新绩效存在显著负效应,而高管团队任期和职业经历异质性却能显著改善企业创新绩效。同时,管理自主权对高管团队异质性与企业创新绩效的关系具有部分调节效应。具体而言,企业所有制性质负向调节了高管团队职业经历异质性与企业创新绩效的关系,而两职兼任正向调节了高管团队职业经历异质性与企业创新绩效的关系。
