20世纪人类社会在经济、社会、文化等各个方面都取得了巨大的进步 ,但是经济的发展却给资源、环境造成了严重的破坏。中国必须走可持续发展的道路。传统的国家技术指导思想导致了有增长无发展的现象十分普遍 ,它单纯的追求经济效益的提高而忽略了社会效益。经济的发展以资源、环境的破坏为代价。实施可持续发展战略 ,使传统的技术指导思想发生了重大改变 ,科技发展在一定程度上可以解决我们面临的资源和环境问题 ,促进经济、生态和社会实现可持续发展。 相似文献

Recent studies have proposed alternative birth outcome measures as means of assessing infant mortality risk; nevertheless,
there hasn’t yet been an integrated analysis of these approaches. We review 14 strategies, including various combinations
of birth weight, gestational age, fetal growth rate, and Apgar scores—as predictors of early neonatal, late neonatal, and
postneonatal mortality, and infant mortality. Using the NCHS linked birth/infant death file for 2001, we construct multivariate
logit models and assess the associations between each of the 14 key birth outcome measures and four mortality outcomes. We
find that all evaluated birth outcome measures are strong predictors, but Apgar scores are the strongest among all models
for all outcomes, independent of birth weight and gestational age. Apgar scores’ predictive power is stronger for Mexican-,
white-, and female-infants than for black- and male-infants. Second, all birth outcome measures remain significantly associated
with mortality, but their predictive power reduces drastically over time. These findings suggest a rule of thumb for predicting
infant mortality odds: when available, Apgar scores should always be included along with birth weight (or LBW status) and
gestational age. Additionally, these findings argue for the continued study of low birthweight, gestational age, and Apgar
scores as independently salient health outcomes. 相似文献

Based on ethnographic fieldwork that took place in 2014 in two Irish primary Muslim schools in the Republic of Ireland, this article draws from both observations of Arabic classes from fourth and fifth classes as well as semi-structured interviews with teachers and parents. The research findings explore the content of and approaches towards the teaching of Arabic and the views held by participants towards the learning of Arabic as part of Islamic religious education. The study reveals the diversity of views that exist and questions the importance of learning Arabic, as part of formal religious education for young Muslims living in non-Muslim pluralist societies. The author concludes with some implications from the study and offers some direction for Muslim schools as it relates to teaching Arabic and, more broadly, to Islamic religious education of young Muslims in Western contexts. 相似文献

一、统计整体功能在实践中不断发展在认识上逐步深化1989年8月,国务院批准的国家统计局《关于加强统计工作,充分发挥统计监督作用的报告》(以下简称国办39号文件)明确指出,要“深化统计体制改革,切实加强对统计工作的集中统一领导,进一步把统计部门建设成为社会经济信息的主体部门和国民经济核算的中心,成为国家重要的咨询和监督机构。”这是在总结和概括我国四十年特别是近十年来统计实践经验,并借鉴国际先进经验的基础上提出的。它既简洁明了地规定了统计部门的基本职能,明确了我国统计改革和统计现代化建设的方向,又比较充分地体现了统计工作在现代国家管理系统中的重要地位和作用。 相似文献

The autoregressive conditional intensity model proposed by Russell (1998) is a promising option for fitting multivariate high frequency irregularly spaced data. The authors acknowledge the validity of this model by showing the independence of its generalized residuals, a crucial assumption of the model formulation not readily recognized by researchers. The authors derive the large‐sample distribution of the autocorrelations of the generalized residual series and use it to construct a goodness‐of‐fit test for the model. Empirical results compare the performance of their test with other off‐the‐shelf tests such as the Ljung–Box test. They illustrate the use of their test with transaction records of the HSBC stock. 相似文献

Correlation clustering problem is a clustering problem which has many applications such as protein interaction networks, cross-lingual link detection, communication networks, and social computing. In this paper, we introduce two variants of correlation clustering problem: correlation clustering problem on uncertain graphs and correlation clustering problem with non-uniform hard constrained cluster sizes. Both problems overcome part of the limitations of the existing variants of correlation clustering problem and have practical applications in the real world. We provide a constant approximation algorithm and two approximation algorithms for the former and the latter problem, respectively.

在慈善活动中,政府的定位应当是慈善事业的适度推动者和慈善活动的有效监督者。从慈善事业的适度推动者出发,我国现行慈善捐赠体制应建立突发公共事件慈善调控平台,弱化政府募捐主体资格,完善政府购买慈善服务制度。从慈善活动的有效监督者出发,政府应联合多部门进行全方位监督,与社会第三方监督机构合作,建立慈善公益诉讼制度。 相似文献
