Say-on-pay judgements: the two-strikes rule and the pay-performance link

We undertake an experiment to explore shareholder voting behaviour when the pay-performance link is weak or strong; and when there has (has not) been a first strike in the preceding year. We find shareholders are more supportive of a remuneration package evidencing a strong pay-performance link than a weak link. Further, shareholders are less supportive of a remuneration package when there has been a first strike in the preceding year than when there has not been a first strike. Importantly, we find that a first strike reduces the effect of the pay-performance link on voting intentions.     

基于相关峰数量统计的诱骗信号快速识别

针对采用直接序列扩频（DSSS）体制的无人机卫星测控前向链路，提出了一种基于相关峰数量统计的诱骗信号识别方法。该方法将同模式的诱骗信号等效为多径信号，利用匹配滤波器对接收信号进行处理，通过迭代算法调整相关峰判决门限，并统计一段时间内的相关峰数量来识别诱骗信号。在扩频码周期为128，正交相移键控(QPSK)调制，1/2码率的信道编码，Es/N0为3 dB，1 024个码周期的统计周期，诱骗信号和合法信号延时大于1个码片长度的情况下，该方法可快速有效地识别诱骗信号。     

Estimating Precision and Recall for Deterministic and Probabilistic Record Linkage

Linking administrative, survey and census files to enhance dimensions such as time and breadth or depth of detail is now common. Because a unique person identifier is often not available, records belonging to two different units (e.g. people) may be incorrectly linked. Estimating the proportion of links that are correct, called Precision, is difficult because, even after clerical review, there will remain uncertainty about whether a link is in fact correct or incorrect. Measures of Precision are useful when deciding whether or not it is worthwhile linking two files, when comparing alternative linking strategies and as a quality measure for estimates based on the linked file. This paper proposes an estimator of Precision for a linked file that has been created by either deterministic (or rules‐based) or probabilistic (where evidence for a link being a match is weighted against the evidence that it is not a match) linkage, both of which are widely used in practice. This paper shows that the proposed estimators perform well.

论思想政治理论课教学语言设计的基本环节与着力点

思想政治理论课教学语言设计是沟通“教材语言”与“教学语言”的桥梁，是增强教学实效的重要前提。做好思想政治理论课教学语言设计，必须从课程教学要求出发，把握课堂导入语言设计、叙述语言设计、情境语言设计、启发语言设计、幽默语言设计、结课语言设计六大基本环节。同时，还要抓实抓好吃透教材、了解学生、优化案例、积累语料四个着力点。     

Challenges and prospects of HRM in developing countries: testing the HRM–performance link in the Eritrean civil service

In this article, the authors examine how, when and to what extent HR practices affect performance at the employee level. As performance is a multi-faceted and complicated concept, HRM outcomes were used as mediating factors between HR practices and employee performance. The data were collected among civil servants in Eritrea, Africa's youngest and poorest country. Although the results generally are in line with previous studies using Western data, their implications in this particular country may be different. Therefore, the challenges and prospects of HR practices in Eritrean civil service organizations are critically analysed and discussed. In the authors' opinion, that the Eritrean economic and political environment within which HR practices operate has not been conducive in maximizing the impact of HR practices on performance. These findings highlight the situation of most developing countries.
