Impact of an Overt Response System on Staff Performance and Maintenance of Computer-Based Instruction

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted.     

An EWMA chart for monitoring process mean

In the statistical process control literature, there exists several improved quality control charts based on cost-effective sampling schemes, including the ranked set sampling (RSS) and median RSS (MRSS). A generalized cost-effective RSS scheme has been recently introduced for efficiently estimating the population mean, namely varied L RSS (VLRSS). In this article, we propose a new exponentially weighted moving average (EWMA) control chart for monitoring the process mean using VLRSS, named the EWMA-VLRSS chart, under both perfect and imperfect rankings. The EWMA-VLRSS chart encompasses the existing EWMA charts based on RSS and MRSS (named the EWMA-RSS and EWMA-MRSS charts). We use extensive Monte Carlo simulations to compute the run length characteristics of the EWMA-VLRSS chart. The proposed chart is then compared with the existing EWMA charts. It is found that, with either perfect or imperfect rankings, the EWMA-VLRSS chart is more sensitive than the EWMA-RSS and EWMA-MRSS charts in detecting small to large shifts in the process mean. A real dataset is also used to explain the working of the EWMA-VLRSS chart.     

基于语言磨蚀理论视角下的维吾尔族大学生英语教学

20世纪80年代在语言磨蚀领域已有相关理论形成,基于此领域中的回归假说、语言干扰、关键阈值、语言提取失败和语言的动态系统理论,依据维吾尔族大学生特殊的英语学习现状,据此得出母语为维吾尔语非英语专业的民考汉大学生的英语教学的一些启示,也为他们的英语保持给予一些探索性思考。     

南海地缘形势与中国政府对南海权益的维护——以20世纪六七十年代南海争端为考察中心

20世纪六七十年代,美、前苏联出于争夺世界霸权的需要,对南海争端采取了不同的政策,南海地区＂边缘地带＂特性进一步凸显。在此背景下,菲律宾、越南和马来西亚等国强占南海岛礁、瓜分海域、掠夺资源。在维权斗争中,中国政府不断地进行南海诸岛主权宣示,抗议周边国家对中国海洋国土主权的践踏,收复被占西沙岛礁,并采取切实措施加强海疆国防建设。     

“烘云托月”与“说不可说”冯友兰新理学“负方法”的关学阐释

在冯友兰新理学关于方法论的论述中，其用“负方法”对形而上学的“讲述”对美学有着深刻的启示意义，甚至可以说它本身就涵蕴着丰富的关学意味。道家的方法、禅宗的方法和诗的言说，是“负方法”的三种典型言说方式，这三种言说形式具有美学阐释的可能性，表现在直觉性、神秘性、超越性和浑整性4个方面。     

Emergency Law in China: Its Formation,Present State and Future

中国非常法律的形成, 是为了应对紧急事件。这类法律由法律法规、应急预案和 军事法规等组成, 规定了战争状态、紧急状态和应急状态三种非常状态, 致力于建构 专业化大分工基础上的综合统一体制。在实践中, 应急预案取代了法律法规, 成为紧 急事件治理的基本规范依据; 政府和武装力量处于主导地位。中国非常法律基于必要 而形成, 其适用具有临时性, 主要内容具有授权性和预防性。非常法律未来发展的主 要目标是: 与中国特色社会主义法律体系衔接, 制定紧急状态下的基本法, 完善非常 法律的各项具体机制。

关键词: 非常状态 综合治理 执行主导 预防性法律

China’s emergency laws have emerged as a result of dealing with crises. They comprise laws and regulations, emergency plans, and military regulations, and define three exceptional or emergency states: war, emergency and emergency response, with the aim of constructing a comprehensive integrated system based on the specialized division of labor. In practice, however, emergency plans take the place of laws and regulations and provide the fundamental normative basis for tackling emergencies, with government and the military playing the dominant role. Developing out of necessity and possessing temporary applicability, China’s emergency laws are characterized by authorization and prevention. Integrating emergency law with the socialist legal system with Chinese characteristics, formulating basic law for emergency situations and improving the specific mechanisms of emergency law should be regarded as major steps in its future development.

侵犯著作权行为的刑事法分析

侵犯著作权的行为在我国近年有愈演愈烈的趋势,并且产生了一些新的侵权行为。相形之下,现行刑法中的相关规定在打击侵犯著作权行为的实践中渐显滞后。综观我国侵犯著作权立法的历史沿革和现行刑法中有关侵犯著作权罪的犯罪构成,结合司法实践,要从扩展刑法对著作权的保护范围,取消犯罪主观案件中的非法营利目的,侧重于对被害人的实质补偿,修改罚金刑、增强其可操作性,确立对侵犯著作权犯罪以自诉为主、公诉为辅的犯罪追诉模式和充分保护著作权人的权益以及社会公共利益等方面,进一步完善我国侵犯著作权罪的相关规定。     

Optimal scheduling replacement policies for a system with multiple random works

From the economical viewpoint in reliability theory, this paper addresses a scheduling replacement problem for a single operating system which works at random times for multiple jobs. The system is subject to stochastic failure which results the imperfect maintenance activity based on some random failure mechanism: minimal repair due to type-I (repairable) failure, or corrective replacement due to type-II (non-repairable) failure. Three scheduling models for the system with multiple jobs are considered: a single work, N tandem works, and N parallel works. To control the deterioration process, the preventive replacement is planned to undergo at a scheduling time T or the job's completion time of for each model. The objective is to determine the optimal scheduling parameters (T^* or N^*) that minimizes the mean cost rate function in a finite time horizon for each model. A numerical example is provided to illustrate the proposed analytical model. Because the framework and analysis are general, the proposed models extend several existing results.     

What influences the size of child maintenance payments? A register‐based study of maintenance payments in Finland

The aim of this study was to explore how particular economic and demographic factors contribute to the level of the child maintenance payment (CMP) paid by the non‐resident parent. For this study, we used 5‐year longitudinal panel data from years 2009 to 2013 consisting of over 80,000 non‐resident parents from the Finnish Tax Administration and The Finnish Population Register Centre. Results from regression models indicate that the single biggest factor affecting the size of CMPs is the number of dependent children. We found that the non‐resident parent's higher income is associated with higher CMPs and that non‐resident fathers pay on average larger CMPs than non‐resident mothers, even after accounting for differences in income. Unexpectedly, we found that the age of the dependent child did not predict changes in CMPs. This suggests that once formal CMP‐contracts are determined between the parents, they are seldom changed. Our results suggest that some degree of mandatory periodic review for maintenance contracts is worth considering.
