Assessing the Gender Invariance of the Modern Homonegativity Scale

The measurement invariance of the Modern Homonegativity Scale (MHS) was examined among heterosexual female (n = 449) and male (n = 329) university students who were predominantly Mexican American. The MHS demonstrated full invariance of factor loadings and partial invariance of latent intercepts. At the latent mean level, heterosexual men compared to heterosexual women held more negative attitudes toward both gay men and lesbian women. There were no latent mean differences in attitudes toward gay men and lesbian women when rated by either heterosexual men or heterosexual women. The MHS can be used by heterosexual men and heterosexual women to assess their homonegativity.     

莱布尼茨与马克思的中国观之比较

在贸易和资本全球化的世界历史进程中，相隔一个半世纪的莱布尼茨与马克思都热切地关注过中国，由于中国和欧洲的地位发生了根本性转变，致使他们对中国的认识和评价有巨大差别：身处启蒙早期的莱布尼茨几乎把中国当成审美对象，拥有积极和肯定的中国观，指认文化中国的存在及其在哲学与政治、道德实践上可学习和效法的成就；时逢两次鸦片战争的马克思，在总体性思维下看到的则是封闭保守、积贫积弱、生产方式落后并被殖民者蹂躏的天朝帝国———既是道义上值得同情的对象，按照历史逻辑又是必然被瓦解并借助革命运动终将迎来曙光的国度，因而他克服了启蒙后期否定的中国观而走向辩证的中国观。然而，二者对中国的观照又有一致性：都超越狭隘民族主义，秉持人类主义的普遍立场，把中国看成世界的一部分，力图使中国世界化，构建各自进步主义的发展模式；都各为所用地把希望目光投向中国，探寻摆脱生存危机的文明之路，以期开显或拯救现代性。     

Self as enterprise: digital disability practices of entrepreneurship and employment in the wave of ‘Internet + disability’ in China

ABSTRACT

Situated in China’s neoliberal context and its rapid development of information communication technologies (ICTs), this study aimed to examine how disabled people in China transformed themselves into new self-enterprising subjects in the wave of ‘Internet?+?Disability.’ In order to answer this question, this study tried to develop an analytical framework to illustrate the disability practices that situated in the ICTs and neoliberal context, underpinned by the discourse of ‘self as enterprise,’ and demonstrated by the practices of entrepreneurship and employment. Based on the research design of case studies and methods that included ethnographic participant observation and in-depth interviews, this study explained how a disabled entrepreneur, Mr. Yuan, took advantage of the wave of ‘Internet?+?Disability’ to realize his dream of entrepreneurship and face the uncertainties of a precarious entrepreneurship. It also explained how Mr. Yuan’s employees achieved their dreams of employment but suffered the precariousness of enterprising subjects.     

中国共产党百年文艺工作的发展历程、基本经验及当代启示

百年来，在马克思主义理论指导下，党的文艺工作始终坚守“以人民为中心”的初心，致力于民族解放与国家发展大局。从艰辛成长到曲折探索，到蓬勃发展，再到丰富创新，党的文艺工作有辉煌成就，也经历过坎坷曲折，它为百年中国革命、建设与改革事业提供了精神动力，注入了思想活力。党的百年文艺工作坚持以马克思主义文艺观为指导，坚定党在文艺工作中的领导地位，维护人民在文艺工作中的主体地位，并始终把握“弘扬主旋律”的文艺工作主题。昨日之史，今日之鉴。百年历程启示我们，在今后的文艺工作中，要坚持政治性与艺术性的统一、建设性与批判性的统一、娱乐性与教育性的统一，要善于定目标、举旗帜、聚能量，不断展现新时代文艺发展的新风貌。     

Statistical testing strategies for assessing treatment efficacy and marker accuracy in phase III trials

When a candidate predictive marker is available, but evidence on its predictive ability is not sufficiently reliable, all‐comers trials with marker stratification are frequently conducted. We propose a framework for planning and evaluating prospective testing strategies in confirmatory, phase III marker‐stratified clinical trials based on a natural assumption on heterogeneity of treatment effects across marker‐defined subpopulations, where weak rather than strong control is permitted for multiple population tests. For phase III marker‐stratified trials, it is expected that treatment efficacy is established in a particular patient population, possibly in a marker‐defined subpopulation, and that the marker accuracy is assessed when the marker is used to restrict the indication or labelling of the treatment to a marker‐based subpopulation, ie, assessment of the clinical validity of the marker. In this paper, we develop statistical testing strategies based on criteria that are explicitly designated to the marker assessment, including those examining treatment effects in marker‐negative patients. As existing and developed statistical testing strategies can assert treatment efficacy for either the overall patient population or the marker‐positive subpopulation, we also develop criteria for evaluating the operating characteristics of the statistical testing strategies based on the probabilities of asserting treatment efficacy across marker subpopulations. Numerical evaluations to compare the statistical testing strategies based on the developed criteria are provided.     

要素匹配与中国投资效率空间差异性——基于双层嵌套型函数的分解研究

本文基于四要素双层嵌套的生产函数，利用1990-2016年全国层面及省际层面数据测算投资效率，并分析其空间结构特征及演变轨迹，检验投资效率匹配效应影响因素。研究发现：①1990-2016年我国整体投资效率呈下降趋势，资本-技能劳动匹配效应与整体投资效率走势趋同，快速累积的资本存量和不断升级的资本质量与短缺的技能劳动之间矛盾突出。②东中西部地区投资效率增长非一致性明显。东部地区资本相对投资效率明显高于中西部，但下降幅度大于中西部，中西部与东部地区之间差距缩小，其中匹配效应是区域间投资效率非平衡的主要成因。③若产业结构升级的技能劳动需求不能满足，将引发要素错配，不利于有效投资。房价与工资提升分别通过影响技能劳动供给和需求抑制要素匹配效率；教育和公路设施会对地区要素匹配产生积极影响，改善地区间投资效率非均衡性；地区投资效率存在显著正向空间相关性，毗邻地区的要素流动和经济发展相近地区的技术溢出均对投资效率产生积极的影响。     

中国传统行政的善治理想及其现代影响——以黄宗羲为例

中国传统行政理论在长期发展中积累了丰富的内容,形成了完整的理论形态,并在明清之际达到了它近乎顶峰的极限状态,黄宗羲的善治理论就是它在这个阶段的重要代表。黄宗羲视域中的善治在内容及方式上,都延续了儒家传统主流观点。它在内容上首先要求圣王,即唯有圣王才能以“不忍人之心”行“不忍人之政”,所谓善治实际上就是“不忍人之政”;其次它还将善治的具体内容确定为养民与教民,“养民”就是使民足以事父母及畜妻子,养生送死无憾,“教民”就是用圣王学说教育民众,使民衣食住行都合乎礼;再次它还主张治理目的是使民皆“至于至善”和“止于至善”。中国传统行政理论的善治理想在现实中还有强劲的生命力,它既表现为行政的强烈伦理导向,又表现为一种主动作为的积极政府观,还表现为一种彻底的以人为本的人文主义。     

Availability analysis for general repairable systems with repair time threshold

Availability analysis is an important issue in many practical fields. This paper investigates the availability for general repairable systems with repair time threshold. Based on practical applications, a repair time threshold is introduced. If the period of a repair is less than a predefined time threshold, then the system may be considered as working during this period, i.e., the effect of the repair could be neglected. Otherwise, if the period of a repair is longer than the given threshold, then the system is considered as working from the beginning of the system failure until the repair time exceeding the threshold, i.e., the time point of the system down could be delayed. We consider both constant and random repair time threshold. This paper valuates the user-perceived availability, when the user does not experience any service interruption because the duration of repair is too short. The results can be applied in reliability engineering, queueing theory and many other fields. A numerical example for ventilator system is presented to demonstrate the application of the developed approach.     

Explicit analytical solutions for ARL of CUSUM chart for a long-memory SARFIMA model

This paper aims to derive explicit analytical solutions for Average Run Length (ARL) of CUSUM chart for the SARFIMA(P,D,Q)_S process with exponential white noise. Measurement of performance was done with the ARL in terms of percentage error and CPU time. The results obtained from the explicit formulas were compared focusing on the performance using the numerical integral equation (NIE) method. Both methods had similarly excellent agreement with the percentage error at less than 0.25%. Meanwhile, the explicit formulas consumed less CPU time than the NIE method. It is clear that the explicit formulas are a good alternative in real applications.
