Modelling daily multivariate pollutant data at multiple sites   总被引:7,自引:1,他引:6  
Summary. This paper considers the spatiotemporal modelling of four pollutants measured daily at eight monitoring sites in London over a 4-year period. Such multiple-pollutant data sets measured over time at multiple sites within a region of interest are typical. Here, the modelling was carried out to provide the exposure for a study investigating the health effects of air pollution. Alternative objectives include the design problem of the positioning of a new monitoring site, or for regulatory purposes to determine whether environmental standards are being met. In general, analyses are hampered by missing data due, for example, to a particular pollutant not being measured at a site, a monitor being inactive by design (e.g. a 6-day monitoring schedule) or because of an unreliable or faulty monitor. Data of this type are modelled here within a dynamic linear modelling framework, in which the dependences across time, space and pollutants are exploited. Throughout the approach is Bayesian, with implementation via Markov chain Monte Carlo sampling.  相似文献

见义不为现象的法律救治   总被引:1,自引:0,他引:1  
见义勇为立法的重要内容之一,就是规定社会和国家对见义勇为者权益的救济和保护负有不可推卸的义务。作者认为对见义勇为者的权益实行法律保护是救治当前道德冷漠现象的一剂良方,是与现实需要紧密结合的法律规范。它的制定与实施又进一步充实了法律的正义精神,是法律价值的全面体现。但在现阶段我国还不具备相应的历史与现实条件用法律强制的手段推行见义勇为的道德行为。  相似文献

对美国著名汉学家史华兹的代表作<寻求富强:严复与西方>进行文本解读发现:该著所反映出的严复能力观对当代公共管理的创新发展具有重要的启示意义.严复认为中西方的关键性差别在于能力,而隐含其中的是以能力为导向的主体意识和公共意识方面的差距."-3代公共管理的创新发展有必要吸收严复能力观中的思想精髓,以国家能力建构为着力点,以公民启蒙为社会基石,以突显公正为其内在灵魂.对正处于社会转型期的国家而言,努力实现国家能力与公民自由问的平衡是达致善治的关键.  相似文献

荣辱观教育的实现方法   总被引:1,自引:0,他引:1  
进行荣辱观教育是社会主义道德建设的重要任务。荣辱观教育需要坚持正确的荣辱衡量标准,明确义利的辩证统一关系;坚持道德价值的一元与多元的有机结合;坚持原则性与灵活性的结合,使荣辱观教育既具有内在的逻辑性和层次性,又具有现实针对性和可操作性。  相似文献

Low dose risk estimation via simultaneous statistical inferences   总被引:2,自引:0,他引:2  
Summary.  The paper develops and studies simultaneous confidence bounds that are useful for making low dose inferences in quantitative risk analysis. Application is intended for risk assessment studies where human, animal or ecological data are used to set safe low dose levels of a toxic agent, but where study information is limited to high dose levels of the agent. Methods are derived for estimating simultaneous, one-sided, upper confidence limits on risk for end points measured on a continuous scale. From the simultaneous confidence bounds, lower confidence limits on the dose that is associated with a particular risk (often referred to as a bench-mark dose ) are calculated. An important feature of the simultaneous construction is that any inferences that are based on inverting the simultaneous confidence bounds apply automatically to inverse bounds on the bench-mark dose.  相似文献

This article critiques the modernist logical‐positivist ideology that has underscored social work, and interrogates the promise of the development of global standards to re‐inscribe social work into civil society at the global level. The potential pitfalls and dangers of such an initiative are also examined. The development of global standards was born out of an assumption that there is a common core to social work on a global level and on an essential affirmation of humanity and human dignity of all peoples across the world. Global standards might be construed to constitute a hegemonic Western discourse and a denial of context‐specific realities. However, a judicious, sensitive, post‐modernist and critical approach may enhance sensitivity towards difference and a greater appreciation of locally specific realities, within the global sphere.  相似文献

The development of a Municipal Information System, or currently better known as a local spatial data infrastructure, is considered complex due to the required inter-institutional relationships. In many developing countries Geographical Information Systems (GISs) are introduced but the benefits are modest as no changes take place in technical and organisational structure of organisations. Digital databases and computer-aided design (CAD) maps are mushrooming in great variety within different private and public institutions, municipal organisations and even within single departments and with structures similar to the paper period and thus operating on a stand-alone basis.Many national mapping agencies are not able to provide large-scale digital urban base maps, while the absence or low quality of cadastres makes those basic core data sets unavailable or inaccessible. The result is that duplication and incompatible data are frequently observed and also donor-driven stand-alone projects have a limited impact through the lack of institutional embedding and are not able to mature from the project to the institutional level. However, a positive sign is that there is an increasing awareness among data producers and consumers that investments in the development of digital data sets should be combined to reduce costs and increase benefits from especially GIS, and information and communication technology (ICT) in general.Within Trujillo a long-term vision was developed to make full use of ICT and GIS to modernise all operations of the Municipality to increase the efficiency and effectiveness of its tasks. However, large investments are not feasible due to the very limited municipal budgets. To guarantee the support of the municipal council, short-term results are required. This paper describes three ‘products’ as part of the vision to develop through a step-by-step approach a local spatial data infrastructure for Trujillo.The three, rather different, products are:
1. fiscal cadastre, to increase municipal revenues through property taxation;
2. an ‘environmental atlas’ based on a compatible spatial and attribute data sets from a variety of organisations; and
3. a municipal website with interactive GIS and meta data information.
The paper concludes with some comments on the institutional and political requirements for the successful development of a local spatial data infrastructure and stresses that such an infrastructure is not a product but an incremental development process that will progress only in case such a process is simple, cost effective, user-friendly, and flexible with clear products.Political interest and institutional stability and genuine interest for inter-institutional cooperation will add much to the success of this process.  相似文献
