文化产业可持续发展指标体系的探讨

文化产业的可持续发展有"发展度"、"协调度"、"持续度"三个"基本维度"。据此,可以设计这三个"基本维度"作为一级评价指标或子系统,各一级评价指标的下层可再设立若干个二级评价指标。文化产业可持续发展指标体系的建立,可为政府把握文化产业发展现状,对文化产业发展进行及时的分析和监测,制定符合市场规律和文化发展规律的政策措施,引导文化产业的可持续发展,具有重要的参考作用和实用价值。     

民族互嵌式社区治理共同体的系统审视与建构路径——以云南省洱源县郑家庄为考察中心

社会治理共同体视域下推进我国民族互嵌式社区治理共同体建设,既是促进各民族相互嵌入的基本着力点,也是落实民族工作“重在基层”的重要体现。本文通过对郑家庄典型社区进行调查研究,将民族互嵌式社区的系统建构与社会治理共同体建设相结合、相融通,见微知著,研究和探讨多民族社区治理的普遍规律,在共同体叙事中探寻我国民族互嵌式社区治理共同体建构的内在机理与框架体系。郑家庄通过系统推进“居住互嵌、组织互嵌、经济互嵌、文化互嵌与心理互嵌”,探索建构民族互嵌式社区生活共同体、组织共同体、经济共同体、文化共同体与情感共同体,为多民族社区实现“建设人人有责、人人尽责、人人享有的社会治理共同体”目标提供了实践样本。     

网絡协議TCP/IP

网络协议TCP/IP,分别相当于ISO/OSI参考模式中的第四层和第三层,源于美国国防部ARPANET的协议标准.目前,在高档微机工程工作站中得到广泛的应用,并成为工业界的一个“公认”标准. 本文介绍TCP/IP协议,并结合对B-NET(运行于16位微机DUAL系统83和UNIX系统V)中的TCP/IP的提取和分析,着重说明它们的接口及其执行过程机理.

Bayesian model comparison for compartmental models with applications in positron emission tomography

We develop strategies for Bayesian modelling as well as model comparison, averaging and selection for compartmental models with particular emphasis on those that occur in the analysis of positron emission tomography (PET) data. Both modelling and computational issues are considered. Biophysically inspired informative priors are developed for the problem at hand, and by comparison with default vague priors it is shown that the proposed modelling is not overly sensitive to prior specification. It is also shown that an additive normal error structure does not describe measured PET data well, despite being very widely used, and that within a simple Bayesian framework simultaneous parameter estimation and model comparison can be performed with a more general noise model. The proposed approach is compared with standard techniques using both simulated and real data. In addition to good, robust estimation performance, the proposed technique provides, automatically, a characterisation of the uncertainty in the resulting estimates which can be considerable in applications such as PET.     

Confidence intervals for the difference in paired Youden indices

Comparison of accuracy between two diagnostic tests can be implemented by investigating the difference in paired Youden indices. However, few literature articles have discussed the inferences for the difference in paired Youden indices. In this paper, we propose an exact confidence interval for the difference in paired Youden indices based on the generalized pivotal quantities. For comparison, the maximum likelihood estimate‐based interval and a bootstrap‐based interval are also included in the study for the difference in paired Youden indices. Abundant simulation studies are conducted to compare the relative performance of these intervals by evaluating the coverage probability and average interval length. Our simulation results demonstrate that the exact confidence interval outperforms the other two intervals even with small sample size when the underlying distributions are normal. A real application is also used to illustrate the proposed intervals. Copyright © 2012 John Wiley & Sons, Ltd.
