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.

A controlled clinical trial was conducted to investigate the efficacy effect of a chemical compound in the treatment of Premenstrual Dysphoric Disorder (PMDD). The data from the trial showed a non-monotone pattern of missing data and an ante-dependence covariance structure. A new analytical method for imputing the missing data with the ante-dependence covariance is proposed. The PMDD data are analysed by the non-imputation method and two imputation methods: the proposed method and the MCMC method. 相似文献

乐教是理解儒家精神不可忽视的重要方面。乐教扎根于“亲亲”之情,具体体现为与“忧患意识”有别,而与“安”“乐”相协调一致的“怛”和“哀”“悲”之情。此情实质上是超越的天道内化为人的心性而落实下来的生命意义与价值得以呈现的方式。儒者虽深知人生之哀、悲,但以乐入手,解悟和转化现实的人生与宇宙,是一大特色。如此,宗教情怀转化为现实的人生关怀,成为特有的礼乐文明的核心内涵。 相似文献

Abstract: This article explores the relationship between social stratification and the division of household labor by examining how the contribution to housework by husbands in dual-earner families varies across the Japanese social stratification structure. First, I review previous studies concerning the determinants of husbands' participation in housework and construct four hypotheses regarding the relative resources explanation, the time constraints explanation, the ideology/sex role explanation, and the alternative manpower explanation. Second, I examine the empirical support for these hypotheses in dual-earner couples and the effect of social stratification on husband's participation in housework, which has not been studied thus far. Third, I investigate the effect of social stratification in more detail. According to the results of TOBIT regressions and other supplementary analyses, the principal findings are as follows:
- 1)
the relative resources explanation is not supported;

Summary. In longitudinal studies, missingness of data is often an unavoidable problem. Estimators from the linear mixed effects model assume that missing data are missing at random. However, estimators are biased when this assumption is not met. In the paper, theoretical results for the asymptotic bias are established under non-ignorable drop-out, drop-in and other missing data patterns. The asymptotic bias is large when the drop-out subjects have only one or no observation, especially for slope-related parameters of the linear mixed effects model. In the drop-in case, intercept-related parameter estimators show substantial asymptotic bias when subjects enter late in the study. Eight other missing data patterns are considered and these produce asymptotic biases of a variety of magnitudes. 相似文献

Summary. Semiparametric mixed models are useful in biometric and econometric applications, especially for longitudinal data. Maximum penalized likelihood estimators (MPLEs) have been shown to work well by Zhang and co-workers for both linear coefficients and nonparametric functions. This paper considers the role of influence diagnostics in the MPLE by extending the case deletion and subject deletion analysis of linear models to accommodate the inclusion of a nonparametric component. We focus on influence measures for the fixed effects and provide formulae that are analogous to those for simpler models and readily computable with the MPLE algorithm. We also establish an equivalence between the case or subject deletion model and a mean shift outlier model from which we derive tests for outliers. The influence diagnostics proposed are illustrated through a longitudinal hormone study on progesterone and a simulated example. 相似文献

Notwithstanding the rise of evidence-based practice, other tendencieswithin social work scholarship are also discernible. One ofthese is the study of the everyday, routine accomplishment ofpractice, drawing on microsociological methods and techniques.In this article, I apply techniques drawn from narrative anddiscourse analysis to the study of reflective practice accounts,which hold an important place in social work education. In particular,it is relevant to examine the form that reflective accountstake and the rhetorical and narrative devices deployed withinthem to accomplish a competent professional identity. My argumentis not that such accounts of practice are untruthful, ratherI propose that we would do well to move beyond taking texts(and talk) for granted and treating language as merely the mediumfor expressing inner thoughts and feelings. Social work shouldtake seriously the need to explore its modes of representationand to cultivate a more self-conscious approach to the way professionaland client identities are produced in practice. 相似文献
