港口陆路集疏运系统的演化机理——基于基础设施投资政策     

刘沛  穆东 《软科学》2016,(6):119-123

基于复杂系统演化理论,分析港口陆路集疏运系统在基础设施投资政策下的演化机理和政策效果。将基础设施投资政策视为系统的他组织作用,建立系统的演化模型,通过分析系统在政策他组织作用下能否演化至有序状态来判断政策的有效性。以曹妃甸港集疏运系统为例,结果表明:投资公路基础设施不能促使系统向有序状态演化;应首先投资铁路基础设施,以提高铁路运输的竞争力、构建铁路运输与公路运输间合理的竞合关系,有助于促使系统向有序状态演化;码头泊位设施的投资也应在铁路基础设施投资的基础上实施。  相似文献   

我国养老保险制度演变与政府责任   总被引：11，自引：1，他引：11  

杨方方 《中国软科学》2005,(2):17-23

养老保险制度自从建立以来,就在不断地经历调整和演变。从整体上来看,中国养老保险制度正在从传统的单位保险向现代的社会保险演变,目标是建立科学合理的责任共担机制。在这一变迁过程中,政府责任则在从"无所不包"向"有所为、有所不为"迈进。但通过对转型以来政府责任的实证分析发现,不论是政府的规范和设计责任、财政责任,还是监管责任和实施责任履行得都很不充分,有待完善。  相似文献   

1997-2013年中国省域创新差异演化及影响因素分析——基于空间杜宾模型的实证研究     

曾浩 《科技管理研究》2016,(2):14-20

以中国31个省域单元为研究区域,采用空间面板数据,运用探索性空间数据分析和空间计量经济学方法对省域创新差异演化及影响因素进行分析。结果表明：在研究时段1997—2013年间,我国省域创新的空间集聚程度在不断增加,空间邻近效应在不断增强,总体空间差异呈现出扩大趋势;区域创新的核心地区较为稳定在长三角和珠三角地区,核心区域在东部沿海有所收缩的同时在中西部地区有扩张趋势。通过构建空间计量经济学模型,对省域单元创新产出的影响因素进行了实证研究,得出 R＆D 人员全时当量、R＆D 经费支出、高技术产品进出口总额对创新提高的正向效应显著;而相邻空间单元的 GDP 对该省域单元创新产出具有显著的正向效应;技术市场成交额对本省域的创新具有正向效应,但溢出效应不显著。最后提出我国东中西部地区差异性创新提升的对策建议。  相似文献   

How an Evolution View of Workplace Mentoring Relationships Helps Avoid Negative Experiences: The Developmental Relationship Mentoring Model in Action     

Rhianon Washington 《Mentoring & Tutoring: Partnership in Learning》2016,24(4):318-340

In this paper, we explore how the use of a specific mentoring model focusing on the evolution of the relationship between mentor and mentee, may influence the incidence of failure. In our research we employed a case study methodology to examine a regional public service mentoring scheme in the UK where a developmental relationship mentoring model had been developed and used to guide practice. Findings indicated toxicity and negative outcomes may be positively influenced by mentor motivation and emotional intelligence, and can be avoided when there is awareness of how relationships develop and evolve. For example, the use of contracting in the early stages can limit the mismatched expectations that provoke disappointment, but equally mentor actions at other stages play key roles in reducing potential failure. Our study has implications for the enhancement of mentor training and scheme coordination as well as contributing to the understanding of negative mentoring relationships.  相似文献   

Exploring the factors related to acceptance of evolutionary theory among Turkish preservice biology teachers: Toward a more informative conceptual ecology for biological evolution   总被引：1，自引：1，他引：0  

Hasan Deniz  Lisa A. Donnelly  Irfan Yilmaz 《科学教学研究杂志》2008,45(4):420-443

In this study, using multiple regression analysis, we aimed to explore the factors related to acceptance of evolutionary theory among preservice Turkish biology teachers using conceptual ecology for biological evolution as a theoretical lens. We aimed to determine the extent to which we can account for the variance in acceptance of evolutionary theory by using understanding of evolutionary theory, epistemological beliefs, thinking dispositions, and parents' educational level as independent variables. Preservice biology teachers' thinking dispositions, their understanding of evolutionary theory, and their parents' educational level are positively correlated with acceptance of evolutionary theory. We did not find any significant positive correlation between epistemological beliefs and acceptance of evolution because of low reliability coefficients of subscales of the epistemological beliefs instrument. Together they explained 10.5% of the variance. These results suggest that studying the relationship between acceptance of evolutionary theory and other related factors in a multivariate context is more informative than examining the relationship between acceptance of evolutionary theory and other factors in isolation. Our findings indicate that studying a controversial issue such as acceptance of evolutionary theory in a multivariate fashion, using conceptual ecology as a theoretical lens to interpret the findings, is informative. Our results suggest the inclusion of thinking dispositions in conceptual ecology for biological evolution. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 420–443, 2008  相似文献   

我国中小学数学课程中“问题提出”的演变——基于课程标准(教学大纲)的分析     

陈婷  谢升梅  蔡金法 《课程.教材.教法》2021,41(5):82-89

中小学数学课程标准(教学大纲)中对“问题提出”的相关要求影响教科书的编写、教师的教和学生的学。采用内容分析法,对10份涉及“问题提出”的中小学数学课程标准(教学大纲)进行编码,通过定量、定性统计分析发现,中小学数学课程文件中对“问题提出”重视程度逐渐提高,建构起了从宏观到微观的“问题提出”体系;内容表述由单一逐步转向综合;目标要求由模糊笼统趋向于明确具体。未来还需要提高数学课程标准中“问题提出”的实践性;增强课程标准和教科书中“问题提出”的一致性;促进教师成为好的“问题提出”者。  相似文献   

我国基础教育质量监测与评价体系的演进与未来走向     

陈慧娟  辛涛 《华东师范大学学报(教育科学版)》2021,(4):42-52

改革开放以来,我国基础教育质量监测与评价体系经历了以督导评估为依托的萌芽期(1978—2001)、开展教育质量监测的探索和试点期(2002—2014)和监测与评价体系的建设和完善期(2015至今)三个阶段。尽管在价值定位、监测内容、组织实施、结果应用、运行体系等方面取得了一些基本经验,但同时在监测与评价体系建设中也存在一些问题和挑战。基于对历史演进、基本经验和现存问题的分析,基础教育质量监测与评价体系的未来走向需要全面体现和贯彻党的教育方针、宏观调控教育督导定位以发挥监测职能、从监测机构设立走向各级监测体系的内涵建设,并推动信息技术与监测评价的深度融合。  相似文献

五四时期知识分子对社会习俗演进的影响     

邱美珠 《三明学院学报》2003,20(4):21-25

五四时期是中国历史上激烈变革的时代,自西学东渐之时也伴随着西俗东渐的过程。由于中国旧的传统礼俗与现代生活方式格格不入,一批先进的知识分子继承并发展了自鸦片战争以来特别是辛亥革命后中国社会传统习俗演进的丰硕成果,使得我国社会习俗的西化过程基本上沿着文明、进步的正确方向迈进。  相似文献
