订单农业核心价值与创新动能的双重检视

订单农业作为小农户与现代农业有效衔接的重要经营模式,对其核心价值与创新动能进行深入探析意义重大。通过静态混合博弈均衡及多案例比较分析方法,凝练出三个重要结论:(1)订单农业依然具有旺盛的生命力,订单农业的创新首先表现在缔约双方是农业龙头企业与规模化的农民合作社／家庭农场,小农户则通过与合作社、家庭农场实现融合发展来参与订单生产;(2)订单农业的创新还表现在将简单的商品交易契约内化为生产流程中系统的生产阶段性服务契约,订单提供者以社会化服务供应为代价,促使订单承接方让渡／共享生产的管理权限;(3)提供农业生产全流程社会化服务有助于订单履约环境的优化。最后提出针对性政策建议来保障订单农业的稳健发展。     

Retirement patterns in Hong Kong: a censored regression analysis

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model is used to infer the retirement age from people‘s current retirement status and their current age. This model is equivalent to a restricted probit model, and the interpretation of parameters is straightforward. The results clearly show a negative income effect on the retirement decision. The retirement age seems to be positively related to lifetime earnings but negatively related to the rate of decline of earnings with age.

Modeling household fertility decisions with generalized Poisson regression

This paper models household fertility decisions by using a generalized Poisson regression model. Since the fertility data used in the paper exhibit under-dispersion, the generalized Poisson regression model has statistical advantages over both standard Poisson and negative binomial regression models, and is suitable for analysis of count data that exhibit either over-dispersion or under-dispersion. The model is estimated by the method of maximum likelihood. Approximate tests for the dispersion and goodness-of-fit measures for comparing alternative models are discussed. Based on observations from the Panel Study of Income Dynamics of 1989 interviewing year, the empirical results support the fertility hypothesis of Becker and Lewis (1973).

Behavioral evaluation of a state program of deinstitutionalization of the developmentally disabled

The purpose of this study was to evaluate one phase of a statewide program of deinstitutionalizing developmentally disabled individuals. Forty adults who had spent a minimum of six months in community placements were evaluated with respect to changes in behavior associated with movement out of state institutions and into community settings such as group homes and day activity centers. Pre- and post-deinstitutionalization measures were taken with the Behavior Development Survey. Post-deinstitutionalization measures on Cataldo and Risley's Resident Activity Manifest were compared to the same measures obtained on 159 developmentally disabled individuals scheduled for deinstitutionalization. A consistent pattern of positive changes on both instruments favored deinstitutionalization, but changes could not be unequivocally attributed to movement out of the institutions per se.     

汉译佛教词语的确立

由汉字与中国化佛教两要素涵化而成的“汉译佛教词语”,久为东亚各国所通用。在中国和日本,汉译佛教词语构成宗教、伦理、哲学等领域的中坚概念。汉译佛教词语藏于汉译佛典之中,其形成期相当于佛典汉译期,主要在魏晋南北朝、隋唐。汉译佛教词语在中日两国间的互动,则一直延续到近现代。     

An ISO 9001:2000-based framework for realizing quality in small businesses

The purpose of ISO 9001:2000 Quality Management System (QMS) is to provide businesses with a model to grow systematically while assuring the quality of their products. The validity of ISO 9001:2000 QMS stems, largely, from the fact that the best minds worldwide have contributed to its development and maintenance, and the fact that many companies have reported real business gains because of its implementation. Unfortunately, many small businesses fail to survive due to the absence or lack of adequate system for managing quality. An obvious recommendation would be to implement ISO 9001:2000 QMS. Nevertheless, small businesses often cite lack of resources and time as the main reasons for not implementing ISO 9001:2000 QMS.     

我国绿色基础设施的经济价值预算与分析

绿色基础设施是自然的生态基础设施和半自然的市政绿色空间的结合,它遵循自然发展的规律,在改善生态环境和保护生物多样性的同时,也蕴藏着新的经济增长点.本研究尝试构建绿色基础设施经济价值评价指标,测算全国各省的绿色基础设施经济价值(2004-2015),探究其区域分布状况,并进一步运用灰色模型预测2016年、2020年和2025年我国绿色基础设施的经济价值,以期提升人们对绿色基础设施的认识,为在城市规划中建设和完善绿色基础设施提供参考,促进生态环境与经济的良性循环,推动城市可持续发展.     

基于核心素养视域下的学前教育本科专业实训室建设探析

核心素养是世界各国面对21世纪信息时代对公民生活世界和个人自我实现的挑战而要求人才具备的品格和关键能力。学前教育专业是一门实践性强、综合素养要求高的专业,学生只有通过实践、在实践中才能实现全面发展。培养学生的核心素养,实训室的文化建设是基础,它对学生核心素养的培养起着潜移默化的作用;实训室的物质建设是关键,基础实训室、专业实训室有利于牢固学生的文化基础,培养学生的创新和反思批判的科学精神;设计类实训室有利于学生养成自学、乐学、好学的学习品质,提高学生的动手实践能力;综合类实训室可以提高学生的社会参与能力和沟通协作能力,具有服务社会的责任担当;实训室的双师型教师队伍是根本,是学生核心素养能否形成的先决条件。     

基于《巴塞尔Ⅲ最终方案》的弹性杠杆率监管研究

弹性资本充足率监管加刚性杠杆率监管存在机理性缺陷。弹性资本充足率监管会影响刚性杠杆率监管的效果,刚性杠杆率监管也不能体现杠杆累积在时间维度和空间维度风险的变化。若引入弹性杠杆率缓冲,刚性杠杆率监管加弹性资本充足率监管的机理性缺陷就可以避免。因此,有必要实施弹性杠杆率监管,杠杆率的弹性化程度与银行的系统重要性程度相对应。     

农户兼业、生产性服务与水稻种植面积决策——基于11省1646户农户的实证研究

本文基于全国11省1646户农户调研数据,构建实证模型分析了农户兼业、生产性服务与水稻种植面积之间的关系。结果表明,在兼业农户比重和平均兼业水平都很高的背景下,兼业导致的“劳动力流失效应”在纯农户和兼业农户的种植面积决策中均有所体现,并且在一兼农户中表现最为显著,而“投资效应”仅体现在纯农户的种植面积决策上。接受生产性服务有助于提高各类农户的种植面积,能够缓解种稻劳动力流失对种植面积造成的负面影响,同时能够缓解一兼农户农业收入比重下降对种植面积造成的负面影响。由此,加强粮食产业生产性服务体系建设、加大纯农户粮食生产补贴力度等是稳定我国水稻生产的重要举措。
