Whilst Geographical Information Systems (GIS) are now used more commonly in transport research and modelling, GIS techniques were used in this study to select similar sample areas (in terms of geography and census attributes) for data collection. For this purpose, a GIS mapping system for Tyne and Wear, UK, was built. The system included topographic maps of the area, boundary maps of Lower Super Output Areas (LSOA), and aggregated census statistics datasets for LSOAs. Criteria relating to census attributes and the nature of transport were employed to identify ‘hotspots’ by GIS enquiry to provide suitably matching areas, which then formed the basis of the sampling frame.The research project was concerned with commuters’ travel choices and so the study needed to identify commuters. In this case-study context, it is not possible to select fully homogeneous areas, so the GIS ‘hotspots’ approach allowed the identification of areas where there were a high concentration of commuters with multiple alternatives for travel to work. A pilot study showed that the GIS origin-based approach was good in collecting a balanced sample, as compared to an employment-based destination survey. This paper explores the benefits and costs of these origin- and destination-based approaches. In the origin-based home sample, households with paper-based surveys were targeted after identification by GIS. This origin approach requires more data preparation compared to the alternative of an employer-based, destination-based sample that could use online survey methodologies.The paper concludes by identifying GIS as an important tool in selecting a sample area for data collection using multiple criteria, but argues that plans for data collection need to be flexibly constructed to overcome unexpected challenges. Although this paper focuses on a transport research case study, the methodology presented can be applied to survey design and selection of sample areas in other disciplines.  相似文献

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.  相似文献

研究目标:用完整遗漏估计量替代目前使用的未匹配遗漏估计量、逆记录检查遗漏估计量和平衡推算遗漏估计量。研究方法:采取文献解读、成果借鉴和移植及实地调查相结合的方法,研究完整遗漏估计量及其方差估计。研究发现:人口普查遗漏估计不只是要提供遗漏估计值,还要揭示遗漏的原因及其遗漏者的特征;构造普查遗漏估计量,既要包括登记在事后计数调查人口名单而未登记在普查名单的单重遗漏人口,还要包括同时遗漏于这两项调查名单的双重遗漏人口。研究创新:提出完整遗漏估计量。研究价值:完整遗漏估计量有望应用于中国2030年普查遗漏估计,开创世界人口普查遗漏估计应用完整遗漏估计量的先河。  相似文献

中国私营企业的生产率表现和投资效率   总被引:9,自引:0,他引:9  
本文利用第一次全国经济普查数据系统地研究中国私营企业的生产率表现和投资效率问题。样本分析表明,东部地区材料和机械设备制造业的私营企业在劳动生产率和资本生产率上都明显领先于其他地区,然而这种优势主要集中表现在规模较大的企业上。生产函数的估计结果显示各地区大部分行业的资本弹性稳定地处于0.2—0.3之间。对生产率方差的分解表明,地区和行业内部近90%的生产率差异来自TFP的差异,劳均资本的差异只占贡献来源的13%左右。虽然行业间生产率差异的主要来源还是TFP,但地区间的生产率差异则主要来源于劳均资本的差异。资本边际产出在地区间和行业间的不均衡分布意味着部门间存在资本配置的非效率。我们通过模拟实验发现,省际间资本重置给私营制造业带来的潜在产出增长效果比行业间的资本重置更加明显,这意味着私营制造业资本的地区间流动障碍比行业间障碍更为严重。  相似文献

International migration has reached unprecedented scale, diversity and political, economic, social and demographic significance in Asia over the last decade. Despite this data collection of migrant stocks and flows remains very limited in most Asian countries. Accordingly, policy making on migration in the region lacks an evidence base and is influenced by interest groups, anecdotal evidence and prejudice. This paper argues that the heightened security consciousness since 911 together with the development of efficient computer based collection and analysis of migration data systems has created a propitious environment for bringing about a parametric improvement in data collection on international migration in Asia. A number of suggestions are made in this regard, especially the inclusion of relevant international migration questions in the 2010 round of population censuses.  相似文献

采用人口分布的不平衡指数、集中指数、再分布指数、人口分布重心和空间自相关分析方法,基于第二-六次人口普查数据,研究了20世纪60年代以来的山东省人口分布演化的特征和规律.研究结果表明,山东省人口分布总体上呈现西高东低、南高北低的格局,人口密度密集的区域在空间上表现为“X”型;人口再分布先后经历了先弱后强的趋势,1990年后人口分布活跃性增加;人口分布重心在东北-西南方向往返移动;人口分布总体上表现为空间自相关,空间自相关性在降低.  相似文献

A national census provides important information on a country's population that is used in government planning and to underpin the national statistical system. Therefore, the quality of such information is paramount but is not as simple as the crude accuracy of population totals. Furthermore, changes in the pace and nature of modern life, such as the growing geographical mobility of the population, increasingly pose challenges to census practice and data quality. More recently, even the need for a census has been questioned on grounds of financial austerity and widespread availability of alternative population information sources. This article reviews how the modern census originated and how it evolved to confront these challenges, driven by indicators of quality and needs of users, and provides reflections on the future of the census within the national statistical infrastructure. To illustrate our discussions, we use case studies from a diverse range of national contexts. We demonstrate the implications that a country's needs, circumstances and experiences have on the census approach and practice while identifying the fundamental demographic assumptions.  相似文献

The purpose and methodology of the Norwegian census has changed considerably during the last 35 years. While the census was previously the main source of socio-demographic information, it is to day just one of several sources. After an identification number for each individual was introduced and used in various administrative registers, the dominating role of the census has changed dramatically. For some years it has been the policy of Statistics Norway to collaborate with various governmental agencies in order to use administrative registers in statistics production. This policy has been supported politically, and a new Statistics Act has been useful in these efforts. The purpose of this paper is to present the strategy and methodology used to produce statistics in general, census statistics in particular, when based on a combined use of administrative registers and directly collected data. Experiences from Norwegian censuses since 1960 will be presented.  相似文献

Abstract

Around the world “public relations” is confused with “propaganda.” Although “propaganda” has negative connotations today, the authors examine the history of propaganda studies, which is tied to the government-sponsored study of communication. Then they offer a recent example of how the U.S. government used children as messengers of propaganda. By abandoning our prejudices against propaganda, the authors argue we can reconnect public relations with a tradition of scholarship on communication audiences, public communication campaigns, and government propaganda efforts.  相似文献
