V＋Rv带宾语的语义框架

以往关于动结式带宾语的研究往往只注意了能否带宾语及其制约因素,但对所带宾语的种类却极少涉及,而这一问题的解决对机器翻译,尤其是同声传译将起到重要的作用。文章认为每个词在其所处的语言系统中占有特定位置,与系统中的某些词具有优先的或固定的组合搭配关系,即每个词都有其默认状态。以当代认知语言学的理论为指导,文章对V Rv能带什么的宾语,它的识别、提取和匹配及推导进行了讨论,得出结论:V对所带宾语提供可能性,面Rv作出限制和选择,也就是说V Rv能带什么样的宾语是有理可据的,其识别和推导是可能的。     

建设工程管理决策中的系统分析方法

管理决策的科学性取决于管理方法、手段和技术的有效性。基于决策问题的系统分析方法是实施科学决策的基础,决策问题的提出是系统科学发展的动因。建设工程管理决策树立系统观点、应用系统方法进行量化和优化是提高其决策质量的有效方法。从系统分析与决策、建设工程管理决策的系统观以及建设选址问题中系统分析方法的应用三个方面理论与实际相结合,阐明了系统量化与优化对于建设工程管理决策的辅助支持作用,以期增强建设工程管理决策活动应用系统方法的自觉性,提高管理决策的质量和能力,促进建筑业的健康良性发展。     

Threshold decisions: how social workers prioritize referrals of child concern

This paper examines local authority social workers' decision‐making when considering referrals of children, where the concerns are on the margin of child protection procedures. In doing so, it describes the findings of a qualitative research study undertaken in the policy context of attempts to ‘refocus’ social work practice in the late 1990s and early twenty‐first century. Data collection involved interviews with social workers and parents in 23 cases. Conclusions are that referrals were evaluated on the basis of five key factors, specificity, severity, risk, parental accountability and corroboration, the use of which determined whether an initial assessment or an investigation of alleged abuse took place. The analysis builds on previous work in the child protection field, but demonstrates how the application of these factors differs between cases of child concern and cases of child protection. Policy implications concern the complexity of decision‐making in the uncertain context of limited referral information and it is proposed that the simplistic notion of a continuum of abuse is now outdated.

一种基于神经网络和决策树的信用评估新方法

分析了数据挖掘在国内外金融领域的应用及研究现状,提出了一种基于神经网络和决策树相结合的信用评估新方法。该方法通过RBF神经网络,进行条件属性裁减,并利用决策树抽取出评估规则。此方法利用神经网络的“黑箱”工作特性,选择重要条件属性,并利用决策树自动生成评估规则,大大提高了信用评估的效率和客观性。

本族语、目标语和中介语三语相交的二语习得理论模型

依据格语法中的格框架理论分析了英国国家语料库(BNC)中动词adapt, cost和survive的语言使用情况并作了较精细的统计,同时依据格框架理论分析了中国英语学习者语料库(CLEC)中同这三个动词相关的误用、滥用和少用现象,并进行了较精细的统计. 在此分析和统计的基础上,对Harmerly等人的中介语理论模型提出了质疑,进而提出了一个本族语、目标语和中介语三语相交的第二语言习得模型.     

Optimal sampling for repeated binary measurements

The authors consider the optimal design of sampling schedules for binary sequence data. They propose an approach which allows a variety of goals to be reflected in the utility function by including deterministic sampling cost, a term related to prediction, and if relevant, a term related to learning about a treatment effect To this end, they use a nonparametric probability model relying on a minimal number of assumptions. They show how their assumption of partial exchangeability for the binary sequence of data allows the sampling distribution to be written as a mixture of homogeneous Markov chains of order k. The implementation follows the approach of Quintana & Müller (2004), which uses a Dirichlet process prior for the mixture.     

卧式椭圆轨迹振动筛的自定中心问题研究

当振动筛筛箱各点作长轴平行于筛面的椭圆轨迹运动时,这种振动筛的胶带轮不可能只作定轴转动(即自定中心)。如果恰当地选择胶带轮几何中心的偏心值,胶带轮的摆动幅度将减小,因此,胶带的工作情况仍将得到改善。     

Couple Attitudes and Agreement Regarding Pregnancy Wantedness in the Philippines

We compare husbands' and wives' views of the wantedness of their most recent pregnancy in the Philippines, a country where relatively high levels of unintended fertility persist. This research is an extension of earlier work that looked separately at individual men's and women's responses. We analyze survey data for 369 couples and find that those most at risk of experiencing a pregnancy that neither spouse wanted tended to be higher parity couples, those who were more fatalistic, those who were practicing Catholics who attended religious services frequently, and those among whom the husband was the sole breadwinner. Higher parity women and older women were also more apt to experience a pregnancy that was wanted by only 1 spouse. Women who had difficulty discussing sexual matters with their husbands were more likely than other women to have a pregnancy that their husbands wanted but they did not.
