在世界人口城市化的过程中,人们已越来越清楚地认识到大城市规模过份膨胀所带来的危害。由于人口和工业的过份集中,不可避免地导致交通拥挤,能源紧张,污染严重,就业困难,住房和用地不足等一系列社会问题的出现。因此,如何有计划地控制大城市的规模,使城市人口与城市各项事业协调发展,已成为人口城市化过程中迫切需要解决的问题。在谈到控制大城市人口规模时,人们谈论得比较多的是如何控制外地人口的机械迁入和建立卫星城以疏导市区人口,这当然是非常重要的两个方面。但小集镇在促使人口  相似文献

大城市开发区流动人口居住特征研究--以上海浦东新区为例   总被引:14,自引:0,他引:14  
主要采用第五次人口普查数据,对上海开发区--浦东新区流动人口的居住状况进行分析和研究.研究表明流动人口在大城市具有明显的非居民化的居住特征,表现在居住场所集中于城市边缘,居住地更换频繁,居住质量差和居民身份认同感缺乏.为了保障流动人口在大城市的居住健康和大城市整体的健康发展,促进流动人口在城市的居住和谐,有必要采取措施,推进区域产业结构升级,调控城市人口规模,制定流动人口的居住标准,提升住房质量;增进流动人口的居民身份认同,;逐步取消户籍制度,增进本地人口与外来人口的居住融合.  相似文献

一我国目前有城市360个,其中100万人口以上的特大城市22个,城市人口17547万,如果到2000年城市人口发展到4亿,仅接近目前世界平均的40%城市化水平。为了控制大城市的规模,新增加的2亿多城市人口必将大部分流向中小城市。而小城市因其生产力发展水平和城市基础设施等原因,接收有限,势必促使中等城市发展。中等城市和条件较好的中等城市的发展,即可缓解大城市的压力,又可弥补小城市的不足,起着承上启下的作用,并在实践中易于实现。这首先是因为,中等城市分布面广,多数是随着经济发展而形成和发展起来的。通过三十多年的建设,有相当的规模和设施,利于大城市在产业结构调整中进行工业、技术、智力转移和人员流  相似文献

我国自五十年代以来,为了控制大城市的规模,相继在大城市周围建设了若干卫星城镇,来疏散大城市的工业及人口,以解决居住拥挤、交通堵塞、环境污染等一系列矛盾。但大部分未能达到预期的效果。这到底是什么原因,应该怎么办?本文试图从上海一个新兴的卫星城镇——金山卫这个侧面出发,来进行较为深入的探讨。一、概况及其作用金山卫卫星城是本世纪七十年代随着上海石油化工总厂的建设而迅速发展起来的新兴工业城镇,位于上海市西南郊的金山县内,南濒杭州湾,北靠沪杭公路,西与浙江省平湖县接界。整个地区面积9.7平方公里,距市  相似文献

便宜、快速、方便的大城市公共交通系统与长时间、长距离通勤、上下班高峰期"交通拥堵"并存是目前中国大城市发展中面临的主要城市问题。居住与就业的空间失配(职住失衡)被认为是导致以上问题的重要原因之一。以就业可达性方法来测度城市居民的居住与就业(职住)空间关系,并以广州为例,揭示公共交通系统网络下,中低收入人群职住空间关系的特征和差异,以为城市公共住房、公共交通、产业等规划和政策的制定提供有益参考。基于广州案例有两个发现:第一,低可达性人数多于高可达性人数。其中,低可达性"蓝领"较"粉领"多,且其主要居住在非中心城区;而居住在中心城区的高可达性"粉领"人数较"蓝领"多。第二,与国外大城市相似,居住在中心城区能给广州中低收入人群带来一定的就业可达性优势。不同点在于,居住在广州非中心城区的高可达性"蓝领"人数多于居住在中心城区的高可达性"蓝领"。  相似文献

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.  相似文献

En este estudio se analiza el incumplimiento del salario mínimo durante el periodo 2003–2012 en diez países de Europa central y oriental con salario mínimo obligatorio nacional. A partir de los datos de EU‐SILC y la metodología propuesta por Bhorat, Kanbur y Mayet (2013), se cuantifica la incidencia y magnitud del incumplimiento. Se realizan análisis de regresión sobre determinantes individuales, laborales y macroeconómicos. Aunque la incidencia permanece relativamente baja, los trabajadores a los que se dirigen las políticas de salario mínimo parecen los más expuestos a su incumplimiento. Con el tiempo, una mayor incidencia se asocia a una razón más alta entre salario mínimo y salario medio.  相似文献

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.  相似文献

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.  相似文献

While a growing body of research analyses the functional mechanisms of the cultural or creative economy, there has been little attention devoted to understanding how local governments translate this work into policy. Moreover, research in this vein focuses predominately on Richard Florida's creative class thesis rather than considering the wider body of work that may influence policy. This article seeks to develop a deeper understanding of how municipalities conceptualize and plan for the cultural economy through the lens of two cities held up as model ‘creative cities’ — Austin, Texas and Toronto, Ontario. The work pays particular attention to how the cities adopt and adapt leading theories, strategies and discourses of the cultural economy. While policy documents indicate that the cities embrace the creative city model, in practice agencies tend to adapt conventional economic development strategies for cultural economy activity and appropriate the language of the creative city for multiple purposes.  相似文献

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.  相似文献

Despite the establishment of high-tech multinational enterprises (MNEs) in Ireland since the late 1950s, the country did not succeed in closing the technological gap with most of its EU counterparts. The weak National System of Innovation (NSI), and in particular low business and government R&D levels, combined with a lack of research and technology linkages between MNEs and indigenous firms, explain these poor results. However, the Shannon region in the West of the country presents some specific institutional characteristics that could theoretically make the region a strong technological enclave. The various actors in the region - i.e. the administrative, financial, political and research institutions, as well as the business organizations - have indeed infused a new type of economic development. After a brief review of the available concepts and models articulated around these actors and their interrelationships, the paper analyses whether the Shannon region, taken as an illustrative example, mirrors a specific economic and technological localized setting. The study is based on a survey of indigenous and foreign firms.  相似文献

This article reviews discrimination and diversity research published in Human Resource Management (HRM) over the past 60 years. While discrimination and diversity are very different constructs, it is often informative to study them together, because when people recognize each other's diversity, this can result in bias, stereotyping, and discrimination. We conducted bibliographic searches for terms related to discrimination and diversity as well as a manual search through every title and abstract published in HRM over the last 60 years to assess article relevance. The search resulted in 135 research articles with 136 unique studies (i.e., samples) which are reviewed in this article. Sex and race are the demographics that have been examined the most in HRM, while religion has been examined the least. Moreover, the number of studies examining lesbian, gay, bisexual, transgender, and queer (LGBTQ) employees in the workplace in HRM has grown quickly within the past 10 years, culminating in a recent meta‐analysis. Our review looks at some of the earliest research published, the most recent research published, and the overall trends we identified in the research over the years for both discrimination and diversity articles. We then make future research suggestions and recommendations to advance the study of discrimination and diversity in the coming years.  相似文献

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.  相似文献

The Early History of the Cumulants and the Gram-Charlier Series   总被引:2,自引:0,他引:2  
The early history of the Gram-Charlier series is discussed from three points of view: (1) a generalization of Laplace's central limit theorem, (2) a least squares approximation to a continuous function by means of Chebyshev-Hermite polynomials, (3) a generalization of Gauss's normal distribution to a system of skew distributions. Thiele defined the cumulants in terms of the moments, first by a recursion formula and later by an expansion of the logarithm of the moment generating function. He devised a differential operator which adjusts any cumulant to a desired value. His little known 1899 paper in Danish on the properties of the cumulants is translated into English in the Appendix.  相似文献
