论素质教育与教师素质

实施素质教育是我国教育改革的“重点工程”，而素质教育的实施须依赖于广大教师，依赖于广大教师提高自身的思想政治。教育理论、科学文化、教学业务、创造力等方面的素质。广大教师只有努力提高自身素质，才能担负起实施素质教育的重任。     

建设新农村,抑或是推进城市化？

一、“三农”问题是制约中国经济长期发展的主要因素 在我国经济总量迅速增长的今天．由双顺差所导致的外部失衡问题已经成为制约中国经济进一步健康发展的主要矛盾。而导致当前中国经济内外失衡的根源．则是内需问题。很多学者把我国消费不足的主要原因归结为收入增长滞后于经济增长．即劳动和资本的收入份额不等或者消费预期不足等问题。     

上古神话的小说思维

上古神话具备了小说艺术最基本的思维特征,主要表现为以叙事为主的"象""事"融合思维、侧 重于工具理性的"情理"融合思维、最大限度地受制于认知性思维的创造性思维等三个特征。     

绕成绞状纤维的一种微波测湿方法

本文对绕成绞状纤维的微波测湿提出了一种归一化测量——单位线密度衰减,这样,对一定物质而言,在一定温度下,只需一条校准曲线,就可用于不同微波衰减、不同湿量、不同周长的绞状纤维的微波测湿。我们对生丝进行了试验,结果良好。     

Was there compression of disability for older Americans from 1992 to 2003?

Medical advances and the growth of the elderly population have focused interest on trends in the health of the elderly. Three theories have been advanced to describe these trends: compression of morbidity, expansion of morbidity, and dynamic equilibrium. We applied multistate life table methods to the Medicare Current Beneficiary Survey to estimate active and disabled life expectancy from 1992 to 2003, defining disability as having difficulty with instrumental activities of daily living or activities of daily living. We found increases in active life expectancy past age 65 and decreases in life expectancy with severe disability. These trends are consistent with elements of both the theory of compression of morbidity and the theory of dynamic equilibrium.     

Procurement with Reverse Auction and Flexible Noncompetitive Contracts

This article investigates a hybrid procurement mechanism that combines a reverse auction with flexible noncompetitive contracts. A buyer adopts such mechanism to procure multiple units of a product from a group of potential suppliers. Specifically, the buyer first offers contracts to some suppliers who, if accepting the contract, do not participate in the auction while committing to selling a unit to the buyer at the price of the subsequent auction. For the suppliers rejecting the offers, they can join the subsequent auction with the other suppliers to compete on the remaining units. When the buyer offers only one flexible noncompetitive contract, we find that the selected supplier may accept the offer regardless of whether he knows his exact cost information. Meanwhile, the buyer can benefit from offering such a contract, as opposed to solely conducting a regular reverse auction or offering a noncompetitive contract that does not allow suppliers declining offers to join the subsequent auction. Moreover, we find that the suppliers' information about their own costs has a significant impact on the buyer's decision. When the buyer makes multiple offers, we analyze the resulting game behavior of the selected suppliers and demonstrate that the buyer can benefit more than just offering one such contract. Therefore, the hybrid procurement mechanism can be mutually beneficial for both the buyer and the selected suppliers.     

再论我国大学英语教学发展方向：通用英语和学术英语

即将公布的《大学英语教学指南》把学术英语纳入大学英语教学内容中,而《上海市大学英语教学参考框架（试行）》更是提出学术英语核心课程的定位,要求在新生中普遍开展学习。这个新的定位在外语界引起很大的争议,争议很大程度上是对学术英语的误解造成的。学术英语和通用英语的区别不是难度而是目的：前者是基于专业需求驱动的,后者是基于语言学习驱动的。面对经济全球化和高等教育国际化,高校只有走国际化道路,才能培养在专业/行业领域内具有学术竞争力的国际化人才。因此,为了满足学科专业的国际化建设需求,大学英语必须调整定位,教学目的不应再是单纯学习语言或提高人文素质,而必须转向为专业服务,培养学生用英语从事专业学习和研究的学术能力。学术英语培养的不仅是学术英语技能,更重要的是以批判性思维能力为核心的学术素养,这是通识教育在语言教学中的使命。因此,不管学生专业课的教学语言是英语还是汉语,不管学生是研究型大学还是高职高专的,不管其毕业后是从事学术研究还是企业工作,学术英语应是每个大学生的必修课程。     

综合性大学与医学类院校学生无偿献血的动因比较研究

以南京某综合性大学和某医学院校为例,比较两类学校学生在无偿献血认知、献血参与态度及献血动机方面的差异。通过文献研究、专家咨询及焦点小组评分编制调查问卷。认知差异比较采用卡方检验,态度和动机差异采用t检验。综合性大学学生对无偿献血的认知水平较低。医学类院校学生在献血参与态度方面的得分较高,二者在献血感受上无差异。献血动机方面,医学类院校学生献血的利他性得分较高,在两校暂未献血人群中,医学类院校学生自我效能型和献血奖励型动机得分更高。需加强对综合性大学学生献血知识的普及,根据态度及动机差异采取有针对性的献血宣传及招募。     

哲学的伦理化与现代性的重塑

当代哲学发展的一个重要趋向是哲学的伦理化,即哲学经过古代的宗教化和近代的科学化之后而进入道德和伦理之域。哲学发展的这一重要趋向给当代哲学提出的首要和根本任务是"合理的现代性"的塑造和构建,特别是重建价值观和整个价值体系,为人自身的需要和欲望立法,从而有效解决科学性与价值性这一现代性的根本矛盾和悖论。这对于当代中国哲学自身的发展以及对于"中国现代性"的塑造和中国现代化的实现都具有至关重要的意义。     

复杂岩性地区岩性识别与储层预测

中国陆相地层岩性成分较为复杂,岩性波阻抗值常呈多极分布。水动能强度的急剧变化、高频率的水进水退等沉积背景造成了薄互层广泛发育的特点。储层间干涉现象普遍存在,直接影响到地震岩性解释的精度。针对复杂岩性地区岩性–波阻抗关系复杂的特点,系统分析了造成传统地震储层预测方法解释误差的原因。根据复杂岩性的地球物理响应特点,选取对区分复杂岩性敏感的测井参数。同时,将90° 相位化地震数据作为测井参数反演的相对波阻抗约束数据体。研究结果表明,该方法对复杂岩性进行了有效的区分,达到了精细描述复杂岩性地区储层空间发育及平面展布特点的目的。
