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.

Relating ultrasonic vocalizations from a pair of rats to individual behavior: A composite link model approach

Ultrasonic vocalizations (USVs) are crucial in the social behavior of rats. We aim to relate USV rates of pairs of rats to individual activity in an automated home cage (PhenoTyper®) where USVs are recorded per pair and not per individual. We propose a composite link model approach to parametrize a mechanistic “sum‐of‐rates” model in which the pair's USV rate is the sum of the USV rates of individuals depending on their own behavior. In generalized linear models (GLMs), the individual's USV rates are multiplied. We verified through simulation that composite link model gave lower Poisson deviance than GLM. We analyzed the data from an experiment in which half of the cages did allow the pairs to interact (Pair Housing) and the other half did not (Individual Housing). The “sum‐of‐rates” model fits best for Individual Housing and GLM for Pair Housing. An additional simulation study strongly suggests that interaction between rats changes the underlying mechanism for vocalization behavior.     

基于骨干度与网络编码的链路预测模型研究

为了研究网络表示学习在社交网络中链路预测方面的应用,提出了一种基于骨干度与网络编码的链路预测模型(BDLINE)。在网络表示学习算法LINE的基础上融入骨干度算法,通过给一阶相似度和二阶相似度中增添骨干权重,将网络编码到多维向量空间中,调试到最优参数。实验采用2个真实数据的数据集,分别在不同的算法模型上进行多次实验。实验结果表明:在链路预测方面,BDLINE均比其他网络表示学习算法的性能有所提升,AUC评测值更高,预测效果表现得更好。因此,所提出的方法可以方便地提取网络特征信息,更好地处理社交网络在链路预测中的随机性,对社交网络中预测网络节点的关联性和有效性具有一定的参考。

Quality Measurement in Professional Services Firms

The purpose of this paper is to examine the nature of the association between service quality as perceived by consumers and its determinants. In particular, the SERVQUAL instrument is discussed and then it is demonstrated how it can be adapted 1.0 fit the needs of small professional services firms using a CPA firm as an example. The entire analysis can be performed with a spreadsheet package and the results are easy to interpret. The results are presented and the managerial implications are discussed.
