绿色中药产业初见成效 发展任重道远——对汉中市部分中药产业重点发展县的调查

近年来,汉中市实施＂发展绿色产业,建设绿色汉中＂的战略,中药产业逐渐成为汉中经济发展新的增长极。为了解汉中中药产业的发展情况以及银行业机构金融服务支持情况,笔者先后深入勉县、留坝、佛坪等中药材生产形成一定规模的县域,采取与当地政府部门、银行业机构座谈,深入农户中药材种植基地和实地察看加工企业等方式进行了专题调研,分析了其中问题并提出相关建议。     

The Impact of a Third-Party Assurance Seal in Customer Purchasing Intention

ABSTRACT

Although e-commerce is evolving at an incredible speed, asymmetric information and opportunism have increased online purchasing risks and market inefficiencies. The lack of face-to-face contact and the inability of the customer to touch and feel tangible products necessitate that online business must provide customers with reliable information and convince customers of their trustworthiness. While the research on Third-Party Assurance Seals (TPAS) is not new, the effectiveness of TPAS has not been persuasively addressed by empirical studies. Our study is different from previous efforts in that it is comprehensive because it combines consumer trust, perceived risk, and influences of TPAS in the B2C e-commerce context. The results of the study show that (1) the effects of TPAS on perceived risk are channeled through perceived trustworthiness, thus demonstrating the mediating role of perceived trustworthiness in B2C e-commerce, (2) perceived risk, perceived usefulness of website, and subjective norm appear to be significant predictors of intention to purchase from the website, (3) a third-party assurance seal strongly affects online shoppers' perceived trustworthiness toward online retailers, while the seal appears to have little effect on perceived risk directly; perceived risk is strongly associated with intention to purchase from the website.     

Entrepreneurs in the making: Six decisions for fostering entrepreneurship through maker spaces

Maker spaces—shared production facilities offering access to basic and advanced manufacturing technologies—have quickly become the latest must-have for universities, large corporations, and communities looking to foster entrepreneurship and innovation. While the entrepreneurial and educational prospects of maker spaces are certainly intriguing, questions remain concerning their design and effectiveness. Drawing primarily on case evidence and conversations with five maker spaces located across the U.S., we identify and present six key decisions for maker space leaders looking to foster entrepreneurship in their organizations. We conclude with a decision framework for maker space leaders and a series of questions for entrepreneurs as both groups work to pursue entrepreneurship through and in maker spaces.     

Consumption of Movie Experience: Cognitive and Affective Approaches

This study examines the structural relationships among film quality, value, and satisfaction on the perspective of moviegoers. The experience economy concept is employed as the theoretical framework, where moviegoers’ cognitive and affective evaluations are projected in fulfilling their perceived value. Moviegoers’ perceived movie attributes and experiences are assessed to evaluate the moviegoers’ satisfactions through functional and emotional values. In particular, this article investigates how four dimensions of experience mediate the effect of movie attributes on perceived value and satisfaction. A total of 565 samples were analyzed with structural equation modeling to investigate the relationship of ‘quality—value—satisfaction.’ The findings show that two movie attributes (core and peripheral) affect three dimensions of experience (entertainment, educational, and escapist), which in turn influence functional and emotional values, and moviegoers’ satisfaction. The results also confirm that emotional value is a more powerful predictor of moviegoers’ satisfaction than functional value.     

我国城市居民最低生活保障标准的影响因素与效应研究

近年来,我国各地城市居民最低生活保障标准不断提升.本文利用我国36个城市1998-2005年的面板数据,分析影响城市居民最低生活保障标准动态变迁的经济、政治和社会因素及其影响效应,结果显示:城市居民最低生活保障制度是最低生活保障而非基本生活保障;"低保"标准并未有效地缩小贫富差距;"低保"标准对贫困者就业意愿具有较弱的负效应.针对上述问题,笔者提出建议:对应经济社会的发展动态提高标准、施行分层梯度式"低保"标准以及建立互动支持系统,促进"低保"受益者就业.     

农村教育发展的财政保障

长期以来农村教育的特征,说明教育经费短缺一直是农村教育发展的突出矛盾。要对农村教育实施财政保障,须以整顿农村教师队伍为前提,在教育观念、国民经济结构、教育结构、政府预算结构及财政体制等五个方面作战略性调整,同时制止对学生的乱收费。     

消费者创新性与互联网购物

首先,研究引入了部分人口特征和心理特征变量对互联网创新消费者进行了初步的界定;其次研究了消费者创新性对消费者的网购行为的影响。实证结果发现性别、成长环境和收入等人口特征是区别互联网创新消费者的显著变量;另外,研究结果还表明个体功能风险和时尚意识对消费者创新性分别有负面和正面的影响;最后,研究发现消费者创新性对网购行为具有显著的正影响。     

论我国农村经济发展的金融支持

农村资本积累缓慢,存在着严重的供给不足,农村积累资金的一部分又通过其他途径流向城市,更加重了乡村资本的稀缺,阻碍了农村经济的发展.加快农村经济发展的根本途径,是向农村提供金融支持,政府应通过加大对农村公共品和农业基础设施的投入,改善农村投资环境,改革和完善农村金融体系,改革现有的农地制度,为农民、农村提供融资工具,以获取发展的资本来推动农村地区的经济发展.     

基于支持向量回归的现代气象雷达寿命预测

为了准确地预测气象雷达使用寿命, 提高气象雷达运行可靠性、安全性和可维护性,提出了一种新的基于多元回归的气象雷达使用寿命预测框架。在该框架内,采用了支持向量回归(SVR)方法来求解气象雷达使用寿命的多元回归问题;提出了基于SVR的气象雷达特征参数选择FSSSVR（Feature Subset Selection SVR）算法去掉冗余和无效的特征参数。实验结果表明,基于SVR方法的预测算法能够准确地预测气象雷达的使用寿命,能够为雷达全寿命周期管理提供参考依据。     

支持向量机在航材供应模型中的研究

针对部队航材供应量预测过程中,样本采集数目较少的实际情况,采用了一种新的预测方法—支持向量机。该方法基于统计学习理论的原理,较好地解决了小样本的学习问题。并以某部队2000～2007年某项航材供应量为学习样本,建立了该项航材的供应量预测模型。计算结果表明,这种方法比传统的方法具有更少的误差和更好的预测精度。
