居民满意度是衡量迁村并居项目是否成功的重要指标。本文运用实地调查与座谈、二元Logistic回归分析等手段与方法,深入分析了山东省齐河县南北社区居民对迁村并居的满意度及其主要影响因素。研究表明,新社区建设显著提高了农村基础设施和公共服务设施完善程度,改善了居民的生活居住环境。居民的总体满意度水平较高,平均分值达到了8.03;但社区规划功能不足、置换补偿标准不合理等降低了居民的满意程度。受访者文化程度、家庭长期从事非农工作人数、原有房屋价值、家庭农用地面积、合并后家庭生活成本变化、装修及家具购置支出、购买房屋支出、生活居住倾向等因素对居民满意度呈显著影响;总体来看,经济因素仍是影响居民满意度的重要因素。建议政府今后实施类似项目时,应从政策宣传、居民参与、规划设计、补偿方案、迁后发展等方面入手统筹规划,提升居民的参与度及满意度,规避项目实施风险。 相似文献

自然保护区的建设在一定程度上加剧了发展需求与生态保护需求之间的冲突。本文基于自然保护区周边社区农户视角,对自然保护区利弊的农户认知及其影响因素进行了分析。从保护区周边社区农户的角度来看,目前在自然保护区建设中,野生动物致害较为严重,但生态旅游增加了农户收入。此外,农户比较认同自然保护区的生态防护、保护物种资源和生态旅游的功能,但是认为自然保护区政策中补偿金额较小。自然保护区补偿低、林地限制利用和林地面积小构成了社区居民参与保护区内林业经营的主要障碍。通过因子分析和多项Logistic回归分析,结果显示保护区对粮食种植、林业经营、劳动力转移、生态旅游收入、野生动物致害的影响,保护区的物种资源保护、生态旅游、生态防护等功能的实现,保护区政策实施中补偿金额小、补偿金发放不及时等问题,林农参与保护区森林经营中存在的补偿标准低缺乏动力、林地限制利用收益受损、面积太小收益低等障碍,以及性别和人均收入等,均对农户的自然保护区的综合影响认知具有显著性影响。 相似文献

草原生态保护补助奖励政策对牧户非农就业生计的影响 总被引：1，自引：0，他引：1
草原生态保护补助奖励政策是中国保障生态安全和牧民生计的重大举措,但现有研究主要关注其对恢复草地生态的影响,对牧户的适应策略和生计影响的研究较少。本文以内蒙古的呼伦贝尔市、锡林郭勒盟、乌兰察布市和包头市为例,探讨草原生态保护补助奖励政策对牧户非农就业的影响。基于2008—2015年的牧户调研数据和计量经济模型的实证分析,得出如下主要结论：① 虽然补奖政策对多数牧户的非农就业和收入起促进的作用,但没有显著改变牧户以畜牧生产为主的生计方式;② 补奖政策与牧户非农就业和收入呈现倒U型的关系,补贴达到一定程度后会产生收入增长而导致休闲需求增长的效应。这些发现不但揭示了草原生态保护补奖政策对牧民生计的影响,而且具有重要的政策含义。 相似文献

征地补偿农户满意度影响因素及提升路径——以武汉市江夏区为例 总被引：1，自引：0，他引：1
完善土地征收补偿制度,对保障城镇建设用地需求和提高农户生活质量具有重要的意义。本文从顾客满意度理论视角,以武汉市江夏区为例,采用主成分分析法和结构方程模型研究征地补偿满意度影响因素及其之间的关系以及提升征地补偿满意度的路径。研究结果显示:(1)征地补偿满意度的影响因素有补偿程序、补偿标准、补偿方式、补偿分配,且这四大因素之间相互影响,其中补偿程序对补偿标准、补偿方式、补偿分配产生正向影响,补偿标准正向影响补偿分配。(2)加强土地征收补偿宣传工作,可降低失地农户的征地补偿期望值,并且适当提高征地补偿标准,可以最大程度地提升失地农户征地补偿满意度和最大化政府利益,从而实现农户和政府的"双赢"。 相似文献

近年来国家在牧区教育、医疗卫生、社会保障等社会事业方面投入较多,但对草原生态保护和牧业生产的投入力度不足,惠牧的生产性补贴政策明显少于惠农的政策。建立草原生态保护补助奖励机制,根本目的是保护草原生态环境,转变畜牧业发展方式,促进牧民增收,不会对畜产品供应产生影响。 相似文献

鄱阳湖区农户生态补偿意愿影响因素实证研究 总被引：13，自引：5，他引：8
本文运用问卷调查方法和统计学的Multinomial Logistic方法,研究生态补偿机制中微观经济主体-农户的行为与选择的问题,确定农户是否具有生态补偿意愿,及影响农户生态补偿意愿的主要因素。结果表明:有近51.5%的受访农户接受生态补偿政策,23.7%的农户不愿意实施生态补偿政策,还有16.3%的农户不知道该如何选择。选择维持原样的农户占8.51%。根据分析结果,进一步揭示出收入水平的差异在很大程度上影响着当地农户的生态补偿意愿;就业和收入来源的多元化在一定程度上成为激励农户的生态补偿意愿的重要因素;农业比较收益低下是造成家庭人口数量多的农户生态补偿意愿高的根本动因;农业经营者老龄化现象是导致生态补偿意愿下降的重要原因;而农业生产流动资本投入的增多将弱化了农户的生态补偿意愿。由此得出,生态补偿的实施还有待于进一步改进和完善,维持农民基本的生存和发展权利,通过技术培训提高劳动力的就业能力,调整当地产业结构,扶持农业优势(支持)产业形成,提高农业经营者的收益是生态补偿成功实施的重要保证。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
