简论英语习语结构的稳定性

习语对外语学习者来说是重要的环节,也是学习难点之一。本文将英语习语分为可以分析解释的修辞性习语和很难或不必分析解释的非修辞性习语两大类,并主要从探讨习语的活用及如何从语法结构的调整两个方面加以例证,从而说明英语习语的结构是否可以灵活变动。     

英语习语的形音义修辞特色

英语习语是英语词汇的重要组成部分,是各种修辞手段的集中表现,本文从句式、语音、语义等方面,探讨英语习语在形、音、义上的修辞特色,以便更好的理解和应用英语习语,促进英语学习。     

作为公共产品的城市管理--以无锡市为个案

城市管理是城市政府的主要职能,是城市政府为城市社会提供的最主要的公共产品之一。传统理念和体制下,城市管理公共产品供给模式效率十分低下,已不能适应城市发展的形势。在现代公共管理及公共产品供给理论框架内考察城市管理,不失为一种新的视角,是探索城市政府职能转变、城市管理体制创新的有效途径,有利于改善城市政府治理能力,整体推进城市社会的全面进步。     

‘What Was I Thinking?!’ Rhetorical Questions as a Technique to Identify and Explore Impasses in Therapy

Rhetorical questions emerging spontaneously in consultations can be used as a tool for developing self‐reflexivity and exploring the therapeutic alliance in the process of therapy with couples and families. This paper presents a technique based on the enunciation of rhetorical questions, which can point to an impasse in the process of therapy and contain a key to its resolution. The technique focuses on the distinctive feature of rhetorical questions as convening a paradoxical injunction: a question not intended as a question, while uttered as such. The technique in four steps is illustrated by examples from therapy, supervision, consultation, and self‐supervision. Its focus is the interlink between the therapeutic relationship and the process of therapy and it is informed by a second‐order cybernetics approach, dialogical practice, and the systemic literature on emotion. The technique can help develop curiosity in working with families, lead to unforeseen developments, and touch on prejudices not made explicit in previous therapeutic encounters. Whether we are acting as supervisors, therapists, or clients, the creation of a ‘secure enough’ context for rhetorical questions becomes critical to allow freeform exploration.     

Automating argument construction

Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real- world contexts. The result of this work is a body of techniques for automated reasoning from evidence that we call evidential reasoning. The techniques are based upon the mathematics of belief functions developed by Dempster and Shafer and have been successfully applied to a variety of problems including computer vision, multisensor integration, and intelligence analysis.

We have developed both a formal basis and a framework for implementating automated reasoning systems based upon these techniques. Both the formal and practical approach can be divided into four parts: (1) specifying a set of distinct propositional spaces, (2) specifying the interrelationships among these spaces, (3) representing bodies of evidence as belief distributions, and (4) establishing paths of the bodies for evidence to move through these spaces by means of evidential operations, eventually converging on spaces where the target questions can be answered. These steps specify a means for arguing from multiple bodies of evidence toward a particular (probabilistic) conclusion. Argument construction is the process by which such evidential analyses are constructed and is the analogue of constructing proof trees in a logical context.

This technology features the ability to reason from uncertain, incomplete, and occasionally inaccurate information based upon seven evidential operations: fusion, discounting, translation, projection, summarization, interpretation, and gisting. These operation are theoretically sound but have intuitive appeal as well.

In implementing this formal approach, we have found that evidential arguments can be represented as graphs. To support the construction, modification, and interrogation of evidential arguments, we have developed Gister. Gister provides an interactive, menu-driven, graphical interface that allows these graphical structures to be easily manipulated.

Our goal is to provide effective automated aids to domain experts for argument construction. Gister represents our first attempt at such an aid.

A Bayesian sequential design with binary outcome

Several researchers have proposed solutions to control type I error rate in sequential designs. The use of Bayesian sequential design becomes more common; however, these designs are subject to inflation of the type I error rate. We propose a Bayesian sequential design for binary outcome using an alpha‐spending function to control the overall type I error rate. Algorithms are presented for calculating critical values and power for the proposed designs. We also propose a new stopping rule for futility. Sensitivity analysis is implemented for assessing the effects of varying the parameters of the prior distribution and maximum total sample size on critical values. Alpha‐spending functions are compared using power and actual sample size through simulations. Further simulations show that, when total sample size is fixed, the proposed design has greater power than the traditional Bayesian sequential design, which sets equal stopping bounds at all interim analyses. We also find that the proposed design with the new stopping for futility rule results in greater power and can stop earlier with a smaller actual sample size, compared with the traditional stopping rule for futility when all other conditions are held constant. Finally, we apply the proposed method to a real data set and compare the results with traditional designs.

我国新型农民合作社的形态、功能及其发展

按照性质不同,我国的农民合作社可划分为新型农民合作社和传统农民合作社两大类型.新型农民合作社的基本功能是农户间的团结协作和互利互惠,它有利于促进农业产业化经营;抵御农业经营风险;实现农民共同富裕;推进农村民主政治建设.从我国的情况看,在发达国家农业产业化经营的三种模式--综合型模式、合同型模式和合作社型模式中,合作社型模式更适合我国的农业产业化经营.由于当前在发展新型农民合作社中存在的,诸如合作的认识不够明确、合作的环境不够优良、合作的机制不够完善的问题,这需要通过教育普及国际公认的合作经济理论和实务知识;尽快出台<农村资金合作社法>,明确各类农民合作社的主管部门;建立、健全合作社"三会"制度及议事规则.
