相互作用玻色子模型的连续变量表示

本文应用生成坐标方法(GCM)给出了相互作用玻色子模型(IBM)的连续变量表示,统一地处理了球形核和形变核的情形,并对轴对称形变核作出其连续变量表示的数值计算,其结果与IBM代数解(PHINT程序)是一致的.     

学科教学知识新突破:教学策略“U-S”双向共创机理

教学策略由学科知识、教学知识、学生心理引导和教学监控等条件性知识以及教师教学经验、反思、行为习惯等组成,具有理论与实践一体化特征。其中知识部分属于学科教学知识(PCK)范畴,具有情境性和多种知识融合的特征。学科教学知识的“特殊整合”,不仅需要相应的学科知识和教学知识,还需要情境性教学经验。然而,中小学教师有经验缺理论、高校教师有理论没经验的问题普遍存在,形成教学策略与教学行为之间双向转化的瓶颈。为此,大学和中小学教师需要以外部利益驱动构建协同共创平台,在相同教学旨趣吸引下组成优势互补的研发团队,形成突破教学策略转化瓶颈的分层赋能与共创机制。“大学―中小学”(“U-S”)协同共创,应注重从教学策略理论知识传授到教师教学行为转变、从学习名师经验及其教学策略创新到新教学策略文本形成的转化与共创过程,形成特色鲜明的学科教学策略知识,将其以陈述性、程序性、策略性知识形式融入师范生实训教学,进而实现对现有学科教学知识的新突破。只有构建“U-S”共同体,协同实现教学策略的“理—实”双向共创,才能赋予教学策略以“内容、形式和旨趣”三个维度的理论和实践生命力,才能发挥双方优势,形成规模更大的教学策略创新平台。     

鲁迅立人思想的一个侧面──再论《补天》

本文从鲁迅的＂立人＂思想这一角度,阐述《补天》（《不周山》）的思想内蕴,指出《补天》张扬＂新的生命＂意识、弘扬人道主义精神的主题是鲁迅＂立人＂思想的一个侧面,与《狂人日记》、《阿Ｑ正传》等作品形成了思想上、艺术上的互补。因此,《补天》是鲁迅早期的主要作品之一。     

Estimation for Continuous Branching Processes

The maximum-likelihood estimator for the curved exponential family given by continuous branching processes with immigration is investigated. These processes originated from population biology but also model the dynamics of interest rates and development of the state of technology in economics. It is proved that in contrast to branching processes with discrete space and/or time the MLE gives a unified approach to the inference. In order to include singular subdomains of the parameter space we modify the MLE slightly. Consistency and asymptotic normality for the MLE are considered. Concerning the asymptotic theory of the experiments, all three properties LAQ, LAN, and LAMN occur for different submodels     

Bequests as a heir "disciple device."

This paper develops a model ofinter vivos gifts and bequests in a setting of moral hazard and adverse selection. Altruistic parents do not perfectly know how much effort their children make to earn their living, nor do they know their true level of ability.Inter vivos gifts take place prior to the realization of the children's earnings whereas at the moment of bequests, parents do observe them. We show that an optimal transfer policy generally uses a mix ofinter vivos gifts — deemed as more efficient — and bequests — deemed as more redistributive.We are thankful to Allessandro Cigno, Jacques Cremer, Claude d Aspremont and anonymous referees for their comments.Responsible editor: Alessandro Cigno     

体词谓语句的生成条件

体词谓语句是以体词作谓语,能够自由生存的句子,它是现代汉语中一种独立的句型而非动词句的省略。体词具备陈述功能,是其作谓语的语法条件,体谓句的陈述关系,主要是由两个单独体词间的并列、偏正关系,因修饰语的参与转化而来的。从语义角度说,体谓句中主谓两部分的逻辑关系、语义制约,以类的形式出现,是句子赖以存在的基础。     

Network analysis in evaluation: some words of caution

Network analysis, a methodology derived from general systems' theory, can be utilized as a community mental health administrative-evaluation procedure. Evaluation parameters derived from analysis of patient data as they “flow” through a network of agency services, provide measures of systemic functioning. These parameters include “longest paths” and various ratio relationships as evaluation measures of service delivery. The limitations of network analysis are examined by means of conceptual analyses, and phenomena that emerged from research experience. The necessity for both quantitative and qualitative data to ensure a meaningful evaluation of mental health services is explained. Conclusions about the value of the network analysis approach are considered.     

Involving constituents in agency priority setting: a case study

Many government agencies have "constituents" who believe the agencies should hear and consider their needs and desires in establishing program priorities. This article describes how one involves interested constituents (consumers, industry, medical professionals, and state organizations) in the agency's annual priority-setting process. This participation has produced a number of beneficial results-some expected and some unexpected.

基于模糊规划的QFD 系统参数确定方法

针对QFD 系统的内在模糊性,运用带有对称三角形模糊系数的模糊规划理论,提出了一 种确定QFD 系统参数的方法. 并通过工程特性目标值的规范化,定义产品开发总成本函数、工 程特性改进成本函数及改进成本系数等概念,建立了一个QFD 规划模型. 仿真结果表明,该模 型能够帮助开发人员在不确定的、模糊条件下有效确定关联函数及自相关函数,优化顾客需求 的满意水平,确定工程特性目标值,使新开发/ 改进的产品顾客满意度赶上或超过目标市场上 的竞争企业,并满足开发预算约束.
