单用、叠用、连用——代词“如何”的语法、语义分析

“如何”在现代汉语中的使用率稍低一些。不过,它功能较多,能构成各种不同结构的句式。如“如何＋VP/AP”、“NP＋如何”、“无论/不管＋如何”、“V得＋如何”、“如何如何＋AP/VP”、“NP＋如何如何”、“VP＋如何如何”、“如何如何＋NP”等。论文从单用、叠用、连用角度归纳了“如何”的主要用法,并具体解释了它在不同语境下的具体意义。     

强化学习型匝道控制模型的研究

高速公路上的交通堵塞造成了道路利用效率低下，并伴随着能源消耗和环境污染问题，因此各种各样的高速公路控制方法应用于缓解交通堵塞。本文提出强化学习型匝道控制模型，该模型以交通流模拟为预测工具，以人工智能的强化学习为最优化选择模型，并具有一定的自主性、有记忆功能和性能反馈功能，且是一种动态的过程。应用JAVA针对不同的交通状态进行模拟再现，模拟结果表明匝道控制模型对于减少交通堵塞具有显著的效果。     

Economics of Disaster Risk,Social Vulnerability,and Mental Health Resilience

We investigate the relationship between exposure to Hurricanes Katrina and/or Rita and mental health resilience by vulnerability status, with particular focus on the mental health outcomes of single mothers versus the general public. We advance a measurable notion of mental health resilience to disaster events. We also calculate the economic costs of poor mental health days added by natural disaster exposure. Negative binomial analyses show that hurricane exposure increases the expected count of poor mental health days for all persons by 18.7% (95% confidence interval [CI], 7.44–31.14%), and by 71.88% (95% CI, 39.48–211.82%) for single females with children. Monthly time‐series show that single mothers have lower event resilience, experiencing higher added mental stress. Results also show that the count of poor mental health days is sensitive to hurricane intensity, increasing by a factor of 1.06 (95% CI, 1.02–1.10) for every billion (U.S.$) dollars of damage added for all exposed persons, and by a factor of 1.08 (95% CI, 1.03–1.14) for single mothers. We estimate that single mothers, as a group, suffered over $130 million in productivity loss from added postdisaster stress and disability. Results illustrate the measurability of mental health resilience as a two‐dimensional concept of resistance capacity and recovery time. Overall, we show that natural disasters regressively tax disadvantaged population strata.     

互动在认知建构中的定位

认知在互动过程中不断趋同,又不断分化与超越。互动使各种不同表征的认知系统相互作用,联结建构成具有差异的统一体。在互动过程中,互动个体的认知状态经历了＂初始建构者＂＂孤独建构者＂和＂社会建构者＂三个不同阶段。互动建构的知识并非都是真理。互动所形成的稳定语境,即具有排他性,也具有保护性。权力强加于社会,迫使个体参与权力规训的社会互动,使社会语境发生了根本性的改变,但有时权力无法抗拒原有社会语境从而默认原有社会语境的存在。

Adaptive agent-based manufacturing control and its application to flow shop routing control

The manufacturing industry is currently facing unprecedented challenges from changes and disturbances. The sources of these changes and disturbances are of different scope and magnitude. They can be of a commercial nature, or linked to fast product development and design, or purely operational (e.g. rush order, machine breakdown, material shortage etc.). In order to meet these requirements it is increasingly important that a production operation be flexible and is able to adapt to new and more suitable ways of operating. This paper focuses on a new strategy for enabling manufacturing control systems to adapt to changing conditions both in terms of product variation and production system upgrades. The approach proposed is based on two key concepts: (1) An autonomous and distributed approach to manufacturing control based on multi-agent methods in which so called operational agents represent the key physical and logical elements in the production environment to be controlled – for example, products and machines and the control strategies that drive them and (2) An adaptation mechanism based around the evolutionary concept of replicator dynamics which updates the behaviour of newly formed operational agents based on historical performance records in order to be better suited to the production environment. An application of this approach for route selection of similar products in manufacturing flow shops is developed and is illustrated in this paper using an example based on the control of an automobile paint shop.     

对《劳动合同法》立法宗旨的认识

《劳动合同法》从立法之初,其立法宗旨就引发了社会各界的激烈争论,主要集中在立法根据以及＂单保护＂还是＂双保护＂等问题上。应从倾斜保护的角度认识《劳动合同法》的立法宗旨,即《劳动合同法》既不是＂单保护＂,也不是＂双保护＂,而是在保护劳动者权益的同时,兼顾保护了用人单位的利益。     

计算气井储量新方法

提出了采用弹性二相法结合物质平衡方程作为计算全井储量的新方法。弹性二相法主要用于气藏开发进入拟稳态以后，要求压力和产量的测量精确，气藏的工作制度对弹性二相法储量也有很大影响，其计算可靠程度已被矿场实际证实；物质平衡方程在开发初期计算精度不高。将弹性二相法与物质平衡法结合建立多目标优化函数，该方法既能很好地应用弹性二相法，又能体现物质平衡，使得该方法适用范围更广，计算结果更可靠，对致密气藏具有更好的推广应用价值。通过实例气井动态储量进行的验证对比表明，该方法在理论上是合理的，实际验证是可行的。
