School-Based Child-Centered Play Therapy with Hispanic Children: Outcomes and Cultural Consideration.

Hispanic children are the fastest growing segment of the population. Numerous factors place them at-risk for school success. This study examined the effects of Child-Centered Play Therapy (CCPT) compared to a curriculum-based small group intervention with 29 Hispanic children referred for school counseling due to behavior problems. Children were assigned to treatment groups by random drawing within grade levels. Treatment was provided by Hispanic bilingual counselors. Statistical analysis revealed that, according to parent report, children receiving CCPT showed statistically significant decreases in externalizing behavior problems, compared to the curriculum-based treatment group. Effect size calculations revealed that CCPT demonstrated a large treatment effect on externalizing behavior problems and a moderate treatment effect on internalizing behavior problems. Cultural considerations and recommendations for practice and future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

利用地震分形属性钻前预测安全钻井液密度范围

为了对钻井过程中的井壁失稳问题进行有效控制,根据地震和测井信息的分形性质以及它们之间的密切联系,提出了综合利用地震记录的分形属性预测测井曲线并进而在钻前预测安全钻井液密度范围的模型。首先从井旁地震记录中提取出能全面反映地震非线性特征的分形属性,运用能充分利用样本信息的CUSI神经网络,建立已钻井段地震分形属性与测井数据之间的非线性映射模型,通过该模型预测未钻地层的声波和密度测井曲线。在此基础上运用井壁稳定分析模型,计算地层的孔隙压力、坍塌压力和破裂压力,从而在钻前预测安全钻井液密度范围。该方法在西部某油田的应用表明,用地震记录的分形属性钻前预测安全钻井液密度范围的方法具有良好的预测效果。该方法预测精度较高,操作简单易行。     

宽带激光熔覆WCP/Ni基合金梯度复合涂层组织与摩擦磨损特性

研究了铸造WC_P/Ni基合金梯度复合涂层组织与摩擦磨损特性。结果表明,梯度复合涂层与基材实现了良好的冶金结合,涂层内有γ-Ni枝晶组织,γ-Ni＋M₂₃C 6共晶组织以及凝固结晶析出的M₆C、M₂₃C₆、M₇C₃等块状或条状组织;随着铸造WC_P体积分数的增加,复合涂层摩擦系数减小,耐磨性增加。19-4试样的耐磨性最高值为4.61,是基材的3倍以上。梯度涂层的磨损机理为磨粒磨损与粘着磨损的复合作用。

Law,liability and expert systems

This paper examines some of the possible legal implications of the production, marketing and use of expert systems. The relevance of a legally useful definition of expert systems, comprising systems designed for use both by laymen and professionals, is related to the distinctions inherent in the legal doctrine underlying provision of goods and provision of services. The liability of the sellers and users of, and contributors to, expert systems are examined in terms of professional malpractice as well as product liability. A recurring theme indicates that legislators may be inclined to restrict possibilities of liability suits in order to avoid disincentives to the creation of expert systems.     

Research and Design of Network Management Construction Based on Mobile AGENT

The technical characters of mobile agent （MA） originated in the distributional artificial intelligence domain is introduced. A network management construction based on agent （NMCA） is then proposed. The NMCA structure features are elaborated in detail. A prototype design of NMCA is given by using the jKQML programming. The establishment of NMCA platform will be helpful to reduce the correspondence load of network management and improves the efficiency and the expansion ability of network management systems.     

Switching between tasks of unequal familiarity: The role of stimulus-attribute and response-set selection.

It has been reported that it is harder to switch to a strong, well-practiced task from a weaker, less-practiced task than vice versa. Three experiments replicated this surprising asymmetry and investigated how it is affected by a reduction in interference between tasks. Experiment 1 progressively delayed the onset of the stimulus attribute associated with the stronger task. Experiments 2 and 3 separated the response sets of the tasks. Both manipulations reduced, without eliminating, interference of the stronger with the weaker task but reversed the asymmetry of switch costs, resulting in a larger cost of switching to the weaker task. The results are interpreted in terms of a model of the interactions between control input, task strength, and task priming. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
