行政诉讼履行法定职责实体判决论——以“尹荷玲案”为核心

“司法审查有限原则”是行政诉讼法的基本原则,这导致了“履行法定职责实体判决”存在争议。“尹荷玲案”不但证成了履行法定职责实体判决存在的正当性,而且明确了该判决适用的“双阶要件”,即“理由具备、事实清楚、法律规定明确”的一般要件,与“法效果唯一性”的特别要件。其中“法效果唯一性”分为两种情况:一是羁束行政行为,二是行政裁量收缩为零,这恰与《行政诉讼法》修改后“给付判决”与“履行判决”的规定相契合。纵观司法实践,重做判决、履行判决、给付判决形成了“程序性判决—提示性判决—履行法定职责实体判决”3种判决方式,体现了三者功能的相似性。作为实质化解争议的履行法定职责实体判决,也彰显了司法推动制度发展的功能。     

Socio‐economic stratification of English in globalized landscapes: A market‐oriented perspective

Globalization has dramatically altered the urban societies of Amsterdam and Brussels over recent decades, with intensified socio‐economic inequality, unprecedented levels of multilingualism and the increasing importance of English. In this paper, I examine the use of English in the linguistic landscape of socio‐economically stratified commercial shopping streets in these two second‐tier global cities. I adopt a market‐oriented, contextualized approach to quantitative and qualitative variability in how English emerges in these particular commercial ‘linguistic markets’. McDonaldization in midscale shopping streets occurs alongside downscale and upscale uses of English which are more susceptible to local commercial dynamics, in particular in Brussels. As such, global English in these single city contexts emerges as a heterogeneous and scaled phenomenon shaped by specific local commercial and linguistic market conditions.     

论行政诉讼非法证据类型

非法证据排除规则最早在美国确立并得到发展,形成一套比较完整的体系。我国对非法证据排除规则的探讨很长时期仅停留在理论阶段,2012年《刑事诉讼法》修改中采纳并确立这一证据规则,使其从理论探讨变为实践,也为行政诉讼非法证据排除规则的探讨提供了很好的借鉴。目前,行政诉讼法正处于修改时期,以现有的法律规范为基础探讨行政诉讼非法证据的类型及其判断标准显得尤为必要。     

Independent attributes control chart for Markov-dependent processes

Statistical process monitoring (SPM) is a very efficient tool to maintain and to improve the quality of a product. In many industrial processes, end product has two or more attribute-type quality characteristics. Some of them are independent, but the observations are Markovian dependent. It is essential to develop a control chart for such situations. In this article, we develop an Independent Attributes Control Chart for Markov Dependent Processes based on error probabilities criterion under the assumption of one-step Markov dependency. Implementation of the chart is similar to that of Shewhart-type chart. Performance of the chart has been studied using probability of detecting shift criterion. A procedure to identify the attribute(s) responsible for out-of-control status of the process is given.     

Confidence interval estimation and hypothesis testing for a common correlation coefficient

Several procedures have been proposed for testing the hypothesis that all off-diagonal elements of the correlation matrix of a multivariate normal distribution are equal. If the hypothesis of equal correlation can be accepted, it is then of interest to estimate and perhaps test hypotheses for the common correlation. In this paper, two versions of five different test statistics are compared via simulation in terms of adequacy of the normal approximation, coverage probabilities of confidence intervals, control of Type I error, and power. The results indicate that two test statistics based on the average of the Fisher z-transforms of the sample correlations should be used in most cases. A statistic based on the sample eigenvalues also gives reasonable results for confidence intervals and lower-tailed tests.     

问题类型划分方法视野下的犯罪概念研究

在问题类型划分方法的视野下,犯罪概念问题应该属于纯粹刑法学问题中的解释选择问题,但刑法学界以往有关犯罪概念的讨论却大多将其作为刑法问题中的价值判断问题。由于未能妥当确定犯罪概念的问题类型,从而使学界有关犯罪概念的讨论未能达成最低限度的学术共识。作为纯粹刑法学问题中的解释选择问题,形式与实质相结合的混合犯罪概念不存在被替代的必要性,而犯罪概念也不应被规定在刑法典中。     

Generalized information matrix tests for copulas

We propose a family of goodness-of-fit tests for copulas. The tests use generalizations of the information matrix (IM) equality of White and so relate to the copula test proposed by Huang and Prokhorov. The idea is that eigenspectrum-based statements of the IM equality reduce the degrees of freedom of the test’s asymptotic distribution and lead to better size-power properties, even in high dimensions. The gains are especially pronounced for vine copulas, where additional benefits come from simplifications of score functions and the Hessian. We derive the asymptotic distribution of the generalized tests, accounting for the nonparametric estimation of the marginals and apply a parametric bootstrap procedure, valid when asymptotic critical values are inaccurate. In Monte Carlo simulations, we study the behavior of the new tests, compare them with several Cramer–von Mises type tests and confirm the desired properties of the new tests in high dimensions.     

An algorithmic approach to construct D-optimal saturated designs for logistic model

In this paper, locally D-optimal saturated designs for a logistic model with one and two continuous input variables have been constructed by modifying the famous Fedorov exchange algorithm. A saturated design not only ensures the minimum number of runs in the design but also simplifies the row exchange computation. The basic idea is to exchange a design point with a point from the design space. The algorithm performs the best row exchange between design points and points form a candidate set representing the design space. Naturally, the resultant designs depend on the candidate set. For gain in precision, intuitively a candidate set with a larger number of points and the low discrepancy is desirable, but it increases the computational cost. Apart from the modification in row exchange computation, we propose implementing the algorithm in two stages. Initially, construct a design with a candidate set of affordable size and then later generate a new candidate set around the points of design searched in the former stage. In order to validate the optimality of constructed designs, we have used the general equivalence theorem. Algorithms for the construction of optimal designs have been implemented by developing suitable codes in R.
