宗教信仰与族群边界--以保安族为例

“回回”原为一个以宗教来认同的族群集体。建国以后 ,国家承认了“回回”的民族身份 ,定名为回族 ,并依据斯大林民族定义进一步将原一律包含进“回回人”中的别具自身文化特点的一些群体识别为单独的少数民族 ,如保安族、东乡族和撒拉族。这样 ,在甘青宁地区穆斯林社会中又出现了一道新的社会边界———民族。那么 ,在当代社会生活中 ,在这个由宗教提供最主要的社会互动关联体系的社会中 ,人们如何区分群体 ?怎样确定群体之间的互动规则 ?基于宗教信仰差异的社会边界和国家认定的民族边界分别发挥着什么样的作用 ?社会生活中真实的族群边界是什么 ?本文试图以保安族为例回答上述问题。

The Effects of Multitasking on Operations Scheduling

This study considers a typical scheduling environment that is influenced by the behavioral phenomenon of multitasking. Under multitasking, the processing of a selected job suffers from interruption by other jobs that are available but unfinished. This situation arises in a wide variety of applications; for example, administration, manufacturing, and process and project management. Several classical solution methods for scheduling problems no longer apply in the presence of multitasking. The solvability of any scheduling problem under multitasking is no easier than that of the corresponding classical problem. We develop optimal algorithms for some fundamental and practical single machine scheduling problems with multitasking. For other problems, we show that they are computationally intractable, even though in some cases the corresponding problem in classical scheduling is efficiently solvable. We also study the cost increase and value gained due to multitasking. This analysis informs companies about how much it would be worthwhile to invest in measures to reduce or encourage multitasking.     

Implementing Monte Carlo tests with p-value buckets

Software packages usually report the results of statistical tests using p-values. Users often interpret these values by comparing them with standard thresholds, for example, 0.1, 1, and 5%, which is sometimes reinforced by a star rating (***, **, and *, respectively). We consider an arbitrary statistical test whose p-value p is not available explicitly, but can be approximated by Monte Carlo samples, for example, by bootstrap or permutation tests. The standard implementation of such tests usually draws a fixed number of samples to approximate p. However, the probability that the exact and the approximated p-value lie on different sides of a threshold (the resampling risk) can be high, particularly for p-values close to a threshold. We present a method to overcome this. We consider a finite set of user-specified intervals that cover [0, 1] and that can be overlapping. We call these p-value buckets. We present algorithms that, with arbitrarily high probability, return a p-value bucket containing p. We prove that for both a bounded resampling risk and a finite runtime, overlapping buckets need to be employed, and that our methods both bound the resampling risk and guarantee a finite runtime for such overlapping buckets. To interpret decisions with overlapping buckets, we propose an extension of the star rating system. We demonstrate that our methods are suitable for use in standard software, including for low p-value thresholds occurring in multiple testing settings, and that they can be computationally more efficient than standard implementations.     

Penalized proportion estimation for non parametric mixture of regressions

Abstract

In this article, we propose a penalized local log-likelihood method to locally select the number of components in non parametric finite mixture of regression models via proportion shrinkage method. Mean functions and variance functions are estimated simultaneously. We show that the number of components can be estimated consistently, and further establish asymptotic normality of functional estimates. We use a modified EM algorithm to estimate the unknown functions. Simulations are conducted to demonstrate the performance of the proposed method. We illustrate our method via an empirical analysis of the housing price index data of United States.     

交互认识论：群众路线的新思路

群众路线的认识论是交互认识论,强调了“干-群”双主体之间的对等性、互动性和主体性原则,因而彰显了群众的主体性地位,摒弃了主客体对立的认识论思路,是历史唯物主义在认识论与本体论、辩证法上相一致的表达。通过交互认识,领导与群众形成共同知识与共同信念,在一个不断信息更新、信念修正、信息域和知识域增大的动态过程中,实现领导与群众的利益与责任的一致、手段与目标的一致。     

微技术传播对青年人信仰的影响研究

以微博和微信为代表的微技术深刻影响着青年人的思维方式、行为方式、价值方式。同时,微技术在传播信仰过程中改变了传统的信仰格局,打破了政治输入和输出的传统信仰架构。青年不但成为了微技术信仰语言的创造者,也有着强烈的信仰平等诉求。在微技术时代,实现信仰治理的优化刻不容缓。

信念愿望意图逻辑探析

在理性主体寻求达成其目的的过程中,信念、愿望和意图起着重要的作用。由 Rao 和Georgeff 提出的信念愿望意图逻辑是建立在分支时间可能世界模型的基础之上的。说明了该逻辑框架对意图的重要成分（比如：信念、愿望、意图和承诺）是如何进行形式化的。另外,不同类型的理性主体可以通过添加特定的条件来进行建模。     

一种应用于药品泡罩包装检测的改进分水岭算法研究

针对分水岭算法存在的过分割问题以及泡罩包装药品图像的特点,提出一种改进的分水岭分割算法对泡罩包装的药品进行分割。该方法将形态学重建运算与使用控制标记符的方法相结合,首先对原图像进行开闭重建,根据邻域像素连通性提取重建后图像的局部极大值作为标记,从而抑制其他的局部极小值,然后依据标记对原始的梯度图像进行修正,最后对修改后的梯度图像进行分水岭分割。试验表明,该方法在缺陷药品检测中,可以有效的抑制传统分水岭的过分割,分割效果良好。
