网络环境下高校图书馆读者工作的转变与发展策略

论述了网络环境下高校图书馆读者工作在服务方式、读者教育、服务对象、资源提供、与读者的关系以及馆员的知识结构等方面所发生的变化,指出高校图书馆应该通过建好图书馆网站,丰富数字资源,提高读者网络检索技能,优化馆员的知识结构,进而深化读者工作。     

图式理论与口语产出

图式认知理论认为,人们在理解、吸收输入信息时需要对新输入信息进行解码和编码,编码必须与大脑中的图式网相匹配才能完成信息处理。认识到这一点对提高口语产出能力的培养是十分重要的。在大学外语口语产出训练中,应重视信息输入。朗读和背诵是强化信息输入的一种有效方式。     

农户对农村公共服务的需求意愿分析 ———基于一项全国范围农户调查的实证研究

文章基于一项关于农户对农村公共服务需求意愿的全国范围的调查数据，分析了农户对农村义务教育、农村医疗卫生、农村社会保障、农村文化事业、农村劳动力技能培训这5种农村公共服务的整体需求意愿及不同特征农户需求意愿的差别、农户对5种农村公共服务各个方面要素的需求意愿以及农户对5种农村公共服务需求的优先序。研究结果表明农户对5种农村公共服务的整体需求意愿并不相同，对农村劳动力技能培训的需求最强烈，不同特征的农户的需求意愿也不相同。另外与其他农村公共产品相比，农户对文章所研究的5种农村公共服务的需求意愿比较强烈。     

教育服务产出核算分析

Ecocultural Attributes: Evaluating Ecological Degradation in Terms of Ecological Goods and Services Versus Subsistence and Tribal Values

It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long‐term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical ecosystem degradation; an Indian sacred ground is tarnished if the surrounding natural environment is degraded; a traditional homeland is less valued if the land itself is contaminated. Our argument is that intact natural resources are essential elements of many cultural resources, and this aspect requires and demands adequate consideration (and may therefore require compensation).     

环境分权、地方政府竞争对绿色技术创新影响的“本地—邻地”效应

随着绿色发展成为五大发展理念之一,各地政府推进绿色技术创新成为降低环境污染和提高增长质量的主要途径。为了考察地方政府环境分权和竞争对绿色技术创新影响的“本地—邻地”效应,本文利用非期望产出EBM模型测度绿色技术创新程度,并将绿色技术创新指数引入动态空间杜宾模型。最后,结合2003-2017年中国省级面板数据进行实证分析。研究发现：(1)绿色技术创新具有显著的路径依赖、空间集聚以及邻近地区的策略竞争效应;(2)环境分权对本地和邻地绿色技术创新的影响呈“U型”变动特征,且现阶段并未跨越分权驱动创新的临界点;(3)环境分权与地方政府竞争的交互效应整体为负,环境行政分权、环境监察分权和环境监测分权等不同类型环境分权采取的策略并不相同;(4)区域环境分权产生的绿色技术创新激励效应存在异质性,中西部地区环境分权对绿色技术创新的激励效果更强。     

CEO差序来源对民营上市公司创新产出的影响

基于差序格局理论,将CEO来源按关系亲疏分为本人、亲人、熟人和外人CEO,以2007—2019年民营上市公司为样本,实证研究了CEO差序来源对企业创新产出的直接作用、中介作用和调节作用。结果表明：CEO差序来源对民营上市公司创新产出的影响显著为负,即CEO差序来源越疏远,民营上市公司创新产出越少;创新投入在CEO差序来源对企业创新产出的影响中起到了中介作用;企业的盈利能力和现金持有水平调节了CEO差序来源对企业创新产出的影响。据此,建议民营上市公司在聘请CEO时,优先选择亲人CEO和熟人CEO,在亲人CEO资源缺乏的情况下,可聘用熟人CEO,这样,更能提升企业的创新产出;同时,企业应提高自身盈利能力和现金持有水平,为企业创新活动奠定基础。     

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.     

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。     

Staff rostering in call centers providing employee transportation

We address the staff rostering problem in call centers with the goal of balancing operational cost, agent satisfaction and customer service objectives. In metropolitan cities such as Istanbul and Mumbai, call centers provide the transportation of their staff so that shuttle costs constitute a significant part of the operational costs. We develop a mixed integer programming model that incorporates the shuttle requirements at the beginning and end of the shifts into the agent-shift assignment decisions, while considering the skill sets of the agents, and other constraints due to workforce regulations and agent preferences. We analyze model solutions for a banking call center under various management priorities to understand the interactions among the conflicting objectives. We show that considering transportation costs as well as agent preferences in agent-shift assignments provides significant benefits in terms of both cost savings and employee satisfaction.
