频率不受运放参数影响的文氏桥振荡器

本文介绍一组（12个）新的正弦振荡器，这组振荡器使用两个运算放大器，其振荡频率不受单极点有源元件增益带宽之积的影响。这种特性是由本文所介绍的电路结构取得的，即不需要调节。     

The Lowry Model Revisited: Incorporating a Multizonal Input-Output Model into an Urban Land Use Allocation Model

This paper formulates a new generation of Lowry-style models that combine a multizonal input-output model and an urban land use allocation model. Three different types of models are proposed: 1) an unconstrained model, 2) a primal of a linear programming approach that includes land supply constraints, and 3) a modified dual of the linear programming approach that allocates land based on additional conditions of economic efficiency. The modified dual formulation improves upon the limitations of Lowry models and their derivatives. First, the proposed model has sound theoretical underpinnings that incorporate the production theory of input-output models and the behavioral theory of optimization models. Second, the proposed model allocates land on the basis of economic efficiency by imposing a procedure that equalizes shadow prices. And third, the proposed model is an optimization model that fully accounts for the spatial and sectoral relationships of multiplier effects determining land use demand.     

"无过错责任"不是"猛虎下山"——对《最高人民法院关于审理触电人身损害赔偿案件若干问题的解释》的理解

“无过错责任”又称“无过失责任”、“客观责任”、“危险责任”、“严格责任”或“特殊侵权民事责任”，是指没有过错造成他人损害的，依法应当由与造成损害原因有关的人承担民事责任的确认责任准则。执行这一原则，主要不是根据责任人的过错，而是基于损害的客观存在，根据行为人的活动及所管理的人或物的危险性质与所造成损害后果的因果关系，它是一种不完全具备一般侵权民事责任的成立要件，也不一定直接由实施违法行为人承担主要责任的法律责任承担方式。

Glamour and Value Strategies on the Tokyo Stock Exchange

This paper evaluates the performance of glamour and value strategies and tests the extrapolation model for the Japanese equity market. In general, value stocks outperform glamour stocks by between 6 and 12 percent per annum for the five years after portfolio formation. Evidence from past, future and expected growth provides strong support for the story developed in Lakonishok, Shleifer and Vishny (1994). It is difficult to attribute the value premia to the difference, if any, in risk factors. In addition, the book-to-market premium is much closer to an arbitrage opportunity than the size premium.     

构建社会主义和谐社会与公共关系

构建社会主义和谐社会,是我国全面建设小康社会、开创中国特色社会主义事业新局面的一项重大任务,适应了我国改革发展进入关键时期的客观要求,体现了广大人民群众的根本利益和共同愿望。公共关系作为组织内求团结、外求合作的传播沟通艺术,正是一种追求组织与组织,组织与社会和谐共存、和谐交往、和谐发展的社会活动。文章就公共关系的历史、本质、职能等方面谈公共关系在构建和谐社会中的作用。     

人力资源外包:提升中小企业集聚效应的新途径

一、人力资源外包服务的发展 外包是在20世纪90年代西方企业实施“回归主业，强化核心业务”的大背景下风行起来的一种企业新战略手段。其核心思想是企业在内部资源有限的情况下，为取得更大的竞争优势，仅保留其最具竞争优势的业务，而将其他业务委托给比自己更具成本优势和专有知识的企业。     

CRIME AND POVERTY: A SEARCH‐THEORETIC APPROACH*

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search‐equilibrium model, in which agents choose between formal employment and pursuing crime‐related activities (theft). Prior to their “occupational choices,” agents undertake costly schooling, raising their productivity. Crime acts, in essence, as a tax on human capital by affecting the probability that a worker's earnings (possessions) are subsequently appropriated. There are multiple equilibria. High crime, low levels of educational attainment, long spells of unemployment, and poverty are correlated across them.     

东部沿海八省市利用外资比较分析

随着引进外资量的不断增加，资金短缺局面的改善，我国应转变利用外资战略，更为重视利用外资的质量和绩效。经济发达的东部沿海地区利用了我国绝大部分的外资。本文以我国东部沿海地区三大经济区域（环渤海经济区、长江三角洲、珠江三角洲）的八个省市作为样本，对其利用外资的规模、业绩、质量、效益及潜力进行比较，客观地评价和审视其对外资的使用。     

读奈保尔:从《米格尔街》开始

《米格尔街》是奈保尔早期的一部试笔之作,虽语言和技法都稍显稚嫩,但仍称得上一部不错的短篇小说集。其简洁明快的语言中充满着机智和幽默,人物形象的刻画虽然稍显夸张,但依然可以传达出特立尼达殖民地下层百姓生活的悲欢。文章主要分析了其中一些人物的形象和这些形象产生的原因。
