基于局域网的无数据库教学视频节目点播系统

在视频点播系统的构建中,人们往往注重于系统功能的全面性,而忽视了系统的易维护性和简单实用性。利用ASP脚本对象FileSystemObject的文件管理功能,构建了一个不需要数据库管理的教学视频点播系统,提供了构建简单实用的教学视频节目点播系统的另一种思路。     

农村信息服务现状和农民知识获取能力的分析研究

论文采用抽样调查的方式,对河北省402个村的农村图书资料室的建设现状、图书资料的主要来源、管理员的学历和专业知识结构、资料室的开放时间以及被调查农民的信息需求类别、需求程度、信息获取方式、信息获取愿望进行调查分析,旨在为建立适合农村现状的信息服务模式奠定基础。     

基于农民信息需求的图书馆信息服务研究

在新农村建设过程中,缩小城乡之间的信息鸿沟是一项艰巨的任务。农民的信息需求呈现就近性、多样性和实用性等主要特征,信息需求受多种因素制约。本文在分析农民信息需求表现特征和现实特征的基础上,论述了图书馆对农民实行信息服务应该采取切实可行的策略。

基于UML用例图的网上花店系统需求分析

UML是用于描述、可视化和构架软件系统以及商业建模的标准语言,它的应用是以系统的开发流程为背景的。不同的组织、不同的应用领域需要不同的开发过程,软件系统的开发流程中,需求分析是其中决定性的一步。本文的主旨就在于探讨如何将UML应用于软件的需求分析阶段,并以"网上花店系统"为例进行了UML建模。     

湘西地区农村妇女对全民健身的认同及需求的研究

文章采用文献资料法、实地访谈法、问卷调查法、数理统计法等研究方法,围绕认知、态度和参与及需求方面对湘西地区农村妇女体育进行调查研究.研究结果表明:该地区农村妇女对全民健身计划关注程度低,健身态度积极性不强;认知水平尚处于浅层次上,不能很好的区分体育与劳动,对健身项目的认同表现不同,但该群体对体育在生活中作用的重要性认知较强,体育功能认知呈现多元化;参与情况:妇女参与率低,选择健身项目内容单一,活动时间不具有连续性.开展最普遍的是民族传统体育活动的组织形式以松散、小型的群众自发组织为主;妇女对体育的需求度并不太高,但对体育内容的需求多元化,并针对欠发达地区农村提出如何发展妇女体育的一些建议.     

Is identification with school the key component in the ‘Black Box’ of education outcomes? Evidence from a randomized experiment

In this paper, we follow up the important class size reduction randomized experiment in Tennessee in the mid 1980s (Project STAR) to attempt to further understand the long-lasting influences of early education interventions. While STAR led to large test score benefits during the intervention, these benefits quickly faded at its conclusion. However, research has recently shown that the STAR experiment led to long term benefits, including increases in college entrance exams participation (ACT/SAT), especially for minority students. We collect new follow up data on high school participation in extracurricular activities to examine whether (1) STAR increased participation in high school activities and (2) whether this increase in participation in high school is the explanation behind the long term benefits of the intervention. We find suggestive evidence that STAR did indeed increase some aspects of high school participation, including scholastic honors and participation in sports, especially for minority students. In contrast, we find little evidence that this increase in participation is the mechanism that has conferred higher rates of college-going to the STAR students.     

Full-income and price elasticities of demand for German public theatre

This article provides estimates of price and income elasticities of demand for German public theatre, using a large and reliable data set for 178 theatres over 40 years (1965–2004). It is posited that the consumption of the performing arts is a time-intensive activity for which both a theatre ticket and leisure time are necessary. Thus, the impacts of ‘full-income’ (‘leisure time income’ added to disposable income) and the price of leisure time on theatre attendance are examined. The findings indicate that the demand for the performing arts is own-price inelastic. The disposable income elasticity is significant, positive and equals approximately one. In contrast, the full-income elasticity is well above one and greater than usual income elasticity indicating that the performing arts are a luxury good when leisure time income is included in the consumer’s budget. The positive full-income effect is, however, offset by the negative price of leisure effect indicating that leisure time is a complement for the performing arts. Additionally, three objective quality characteristics of theatrical productions which can positively influence theatre demand are examined.

基于弹性理论——论体育服务产品的供求变化

本文首先对体育服务产品进行界定,然后系统地阐述了在体育服务产品供求变化的过程中,必须借用弹性理论。具体包括需求的价值弹性、交叉弹性和收入弹性,从产品价值、相关产品价格和消费者收入这三个主要要素入手,分析各种要素对产品需求量的影响。     

黄河流域农业需水价格弹性研究

以经济学理论为基础，从研究农业需水价格弹性入手，分析水价对农业需水量的影响，确定二者之间的定量关系。该文应用计量经济学的方法，通过对黄河流域不同灌区建立农业用水需求函数，得出水的需求价格弹性，并进一步研究得出了农业需水价格弹性函数。研究表明水价与需水量和需求价格弹性之间都有明显的相关关系。将以上研究成果在黄河流域农业需水分析中进行了定量的应用研究，结果显示水价调整对该流域的农业需水有明显的抑制作用。
