基于CNP和MAS的航空兵编队协同任务分配

任务分配方法是任务控制过程的重要组成部分,是编队协同作战指挥策略的关键。以合同网协议(CNP)和多智能体系统(MAS)理论为基础,建立了编队MAS结构和基于投标过程的任务分配模型,将任务优先权引入任务分配模型中,可以实现预先任务分配和执行过程中动态任务分配,保证动态环境下编队整体分配效能较优。针对作战想定进行了仿真计算,结果表明,基于CNP和MAS理论的编队协同任务分配具有良好的预先任务分配和实时任务分配效果,能够满足编队作战任务的需要。     

A Librarian's Suggestions on Taking Notes

Abstract

A key factor in ensuring students' academic success is to make certain that they do not feel lost or intimidated when undertaking library research assignments. Classroom faculty and librarians working in collaboration can help ease students' research anxiety by providing them with some simple pre-research tools. Included in this article are “Library Tips for Students,” and for faculty “Guidelines for Designing and Implementing Effective Library Research Assignments,” “Characteristics of Effective Assignments,” and “Pitfalls to Avoid” when designing these assignments. Students, classroom faculty, and librarians benefit when students receive a solid foundation for their research undertakings.     

Discrepancies between school grades and test scores at individual and school level: effects of gender and family background

The purpose of the study was to use multivariate multilevel techniques to investigate whether it was possible to separate different dimensions in grades that relate to subject-matter achievement and to other factors. Data were derived from The Gothenburg Educational Longitudinal Database (GOLD), and the subjects were 99,070 ninth-grade students born in 1987. The analyses were based on subject grades and scores on national tests in Swedish, English, and mathematics. The results showed that, at both individual and school levels, the greatest part of the variance in grades was due to achievement in the different subject areas. At both levels, it was possible to identify a dimension that cut across the grades in all 3 subjects, which suggests that grading is influenced by factors other than achievement. One of the most interesting results concerns the relation between parental education and the common grade dimension at the school level.     

ADDRESSING THE EFFECTS OF ASSIGNMENT STRESS INJURY

The purpose of this article is to present the results of a qualitative study on assignment stress injury within journalism. Thirty-one Canadian journalists and photojournalists participated in the research study. The focus of this article is on recommendations offered by our participants to address the effects of traumatic stress within their profession.     

The Functioning of Single-Case Randomization Tests With and Without Random Assignment

The authors used Monte Carlo methods to examine the Type I error rates for randomization tests applied to single-case data arising from ABAB designs involving random, systematic, or response-guided assignment of interventions. Six randomization tests were examined (permuting blocks of 1, 2, 3, or 5 observations, and randomly selecting intervention triplets so that each phase has at least 3 or 5 observations). When the design included randomization, the Type I error rate was controlled. When the design was systematic or guided by the absolute value of the slope, the tests permuting blocks tended to be liberal with positive autocorrelation, whereas those based on the random selection of intervention triplets tended to be conservative across levels of autocorrelation.     

普通高校分配制度存在的问题及完善建议

我国普通高校现有的分配制度中存在诸如岗位职责不明确、注重身份管理、考核体系不健全、因津贴差距过大而影响激励效果等问题,针对分配制度中存在的这些问题及其影响因素进行了分析,在此基础上就如何完善分配制度提出了一些改进建议。     

劳动争议案件举证责任分配新论

在劳动争议案件中,举证责任的分配意义重大,关系到劳动者权益的维护和劳动法立法目的实现,<劳动争议调解仲裁法>首次以立法的形式对劳动争议案件举证责任的分配作出了较完备的规定,以此为据,劳动争议案件举证责任的分配应以形式分配标准和实质分配标准来进行合理的设计,以体现劳动争议案件的特点,以期实现实质公平.     

区间数指派问题的指派法探研

文中探讨了目标函数的系数为区间数的指派问题的解法．给出了区间数方程解的定义,基于此定义与传统指派问题的匈牙利法原理对区间数指派问题进行求解．然后给出了一算例说明该方法的有效性．     

基于大作业的实践性项目运作模式——经管类专业理论课程实践模式探索

培养学生的实践能力是高等院校的基本培养目标,而如何在不增加实验室、校外实习基地以及保证实践环节不脱离理论教学的前提下,在经管类课程中开展实践教学是众多高校所面临的共同难题。作为教学核心环节之一的课堂教学同样肩负着实践的职责。鉴于此,我们探索出一种在课堂教学中实现实践的新模式,建立了一整套配套保障机制,并进一步阐述了该模式的特点和应用效果,本模式对培养锻炼学生的实践能力具有一定的应用价值。
