资源型城市经济增长:基于生态约束的分析     

李惠娟  龙如银  兰新萍 《软科学》2012,26(6):53-59

提出了新型的产业组织模式——生态产业组织模式,但新的产业组织模式是否能够实现经济增长需要进一步加以证明。为此,把生态约束引入经济系统,构建包含生产部门和R&D部门两部门的生态约束下的经济增长模型,运用最优控制方法研究稳态时经济最优增长路径问题。研究发现,生态约束下资源型城市经济系统的最优增长路径是存在的,在不同的发展阶段,资源型城市生态系统的相关变量变化不同。在资源型城市的繁荣期将其转向生态产业组织模式,可以协调经济增长与生态环境,促进城市的可持续发展。  相似文献   

公民有序参与地方立法的制约因素及解决     

陈俊 《淮南师范学院学报》2013,(6):64-67

公民有序参与地方立法既是我国民主政治建设中的一项重要内容,也是我国地方民主政治发展所面临的重大课题.我国公民有序参与地方立法受到观念因素、体制因素及部门利益因素的制约.为推进公民有序参与地方立法建设进程,必须培植公民现代民主法治观念,加强地方立法机关内设专门机构建设,完善公民有序参与地方立法的程序机制,加快公民网络有序参与地方立法的制度建设.  相似文献

上海市公共体育设施建设效应评价研究          下载免费PDF全文

李陈 《体育科研》2019,(2):21-32

上海市公共体育设施建设的主要矛盾是市民日益增长的多元化体育需求和公共体育设施建设不平衡、不充分发展之间的矛盾。作为迈向卓越的全球城市，上海正为向市民提供多元化需求的公共体育设施而努力。本文根据“30分钟体育生活圈”的要求，对上海市公共体育设施建设效应进行研判，得出：（1）上海市公共体育设施布局呈现等级性，空间上呈现“中心-外围”特征，形成了“市-区-街道”三级空间尺度的公共体育设施空间布局。（2）上海市公共体育设施空间布局与人口密度分布呈正相关关系。健身点密度、市民球场、市民健身房、市民健身步道与人口密度分布呈现较强的正相关关系；农民健身工程与人口密度分布呈现较强的负相关关系。（3）上海市公共体育设施密度区域差异显著。公共体育设施建设正处于数量增加向质量提升的过渡阶段，正建设与卓越的全球城市和社会主义国际化大都市相匹配的公共体育设施与配套服务。（4）上海市公共体育设施建设总体评价较好，但存在难以满足多元化需求等问题。调查显示，居民对上海市公共体育设施建设的总体评价较好，满意度评价较高，但未满足个性化、多元化需求，在软件环境建设上仍有很大提升空间。  相似文献   

Suboptimal reliable guaranteed cost control for continuous-time systems with multi-criterion constraints     

Deng-feng Zhang  Hong-ye Su  Jian Chu  Zhi-quan Wang 《浙江大学学报(A卷英文版)》2008,9(8):1024-1033

The suboptimal reliable guaranteed cost control （RGCC） with multi-criterion constraints is investigated for a class of uncertain continuous-time systems with sensor faults. A fauk model in sensors, which considers outage or partial degradation of sensors, is adopted. The influence of the disturbance on the quadratic stability of the closed-loop systems is analyzed. The reliable state-feedback controller is developed by a linear matrix inequalities （LMIs） approach, to minimize the upper bound of a quadratic cost fimction under the conditions that all the closed-loop poles be placed in a specified disk, and that the prescribed level of H∞ disturbance attenuation and the upper bound constraints of control inputs＇ magnitudes be guaranteed. Thus, with the above muki-criterion constraints, the resulting closed-loop system can provide satisfactory stability, transient property, a disturbance rejection level and minimized quadratic cost performance despite possible sensor faults.  相似文献   

New academics,new higher education contexts: a critical perspective on professional development     

Kasturi Behari-Leak 《Teaching in Higher Education》2017,22(5):485-500

New academics entering higher education are especially vulnerable if teaching in a post-colonial classroom is not foregrounded as an explicit part of their professional induction. Drawing on a study of a professional development programme for induction to teaching, this paper explicates how six new academics confront specific challenges of exclusion, marginalisation, and alienation at institutional, faculty, departmental and classroom levels. Framed by critical and social realist theory, the study uses photo voice methodology to elicit new academics' critical insights in the ‘learning to teach’ frame. The paper asserts new academics must engage in ways that make explicit the racial, gendered and class-based constraints experienced in various university spaces. While the relevance and legitimacy of current professional development programmes depends on their ability to be responsive and socially just, the study also questions whether programmes alone can challenge deep systemic constraints that are reproduced through current university structures and culture.  相似文献   

Allocating Sample Sizes to Reduce Budget for Fixed-Effect 2×2 Heterogeneous Analysis of Variance     

Wei-Ming Luh  Jiin-Huarng Guo 《Journal of Experimental Education》2016,84(1):197-211

This article discusses the sample size requirements for the interaction, row, and column effects, respectively, by forming a linear contrast for a 2×2 factorial design for fixed-effects heterogeneous analysis of variance. The proposed method uses the Welch t test and its corresponding degrees of freedom to calculate the final sample size in a 2-step procedure. The simulation results show that the proposed sample size allocation ratio can minimize the sampling cost, while at the same time the designated power is achieved. The article concludes with a discussion to reiterate the importance of sample size planning, especially for testing the iteration effect.  相似文献   

城市社区养老模式初探——基于结构功能主义视野下的分析     

李晨漪 《陕西教育学院学报》2008,24(4):35-39

我国人口结构转向老龄化,同时社会转型带来了家庭养老功能不断弱化,老年人的养老成为一个显著的社会问题。本文试图从结构分化、功能替代和结构性制约这一结构功能主义的视角来探讨当前我国城市社区养老发展的必然性并探寻这一新型养老模式的发展思路。  相似文献
