元大都戏剧艺人略论

元大都辉煌的戏剧文化是杂剧家和戏剧艺人共同创造的。大都的戏剧艺人的演艺水平很高,一大批演员都具有角色行当上的专长。在大都梨园中不乏夫妻或父母子女同为艺人的,由此形成了一些艺人之家或艺人世家,元代戏剧艺人演艺水平之高,与此种现象有内在联系。此外,大都一些戏剧艺人在文学创作上也有令人瞩目的成绩。     

Toward an integrated Bayesian network approach to measurement error detection and correction

In this article, the quality of data produced by national statistical institutes and by governmental institutions is considered. In particular, the problem of measurement error is analyzed and an integrated Bayesian network decision support system based on non-parametric Bayesian networks is proposed for its detection and correction. Non-parametric Bayesian networks are graphical models expressing dependence structure via bivariate copulas associated to the edges of the graph. The network structure and the misreport probability are estimated using a validation sample. The Bayesian network model is proposed to decide: (i) which records have to be corrected; (ii) the kind and amount of correction to be adopted. The proposed correction procedure is applied to the Banca d’Italia Survey on Household Income and Wealth and, specifically, the bond amounts are analyzed. Finally, the sensitivity of the conditional distribution of the true value random variable given the observed one to different evidence configurations is studied.     

Reasons That Could Lead People to Divorce in an Evolutionary Perspective: Evidence from Cyprus

In the current research, we aimed to identify the reasons that could drive people to get a divorce. In Study 1, we employed qualitative research methods, and we identified 62 reasons that could potentially drive people to get a divorce. Using quantitative research methods, in Study 2 we classified these reasons into 7 broader factors. We found that being a harmful spouse was the most important factor for divorce, followed by incompatibility and in-law problems. We also found significant sex differences in several factors such as women indicating a higher willingness than men to divorce a harmful spouse. In addition, participants with children were less willing to divorce a harmful spouse than those who had no children. Finally, using second-order principal components analysis, we classified the 7 factors into 2 broader domains of reasons for getting a divorce.     

地区收入、食品价格与恩格尔系数

本文以2016年我国31个省级地区截面数据为样本,构建扩展模型考察恩格尔系数与收入、食品价格之间的关系。研究发现,恩格尔系数与地区收入存在显著的负相关性,纳入食品价格后收入对恩格尔系数的影响变得更为显著,二者关系满足恩格尔定律。恩格尔系数和以地区食品价格平价代表的食品价格之间显著正相关,若再考虑其他因素,则食品价格对恩格尔系数的影响会稍有减弱。进一步将食品区分为生活必需型食品与非生活必需型食品,测算得到的基本恩格尔系数、高阶恩格尔系数与收入之间仍呈负相关关系,但与基本恩格尔系数相比,高阶恩格尔系数与收入之间的负相关性更弱。恩格尔系数受生活必需型食品价格的影响强于非生活必需型食品价格的影响,基本恩格尔系数主要受生活必需型食品价格的影响,而高阶恩格尔系数同时受到两类食品价格的影响。     

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。     

Reconsidering the philanthropic foundation minimum payout policy under a “new normal”

With the increasing salience of foundations in many policy fields, and recent changes in market conditions, policies towards foundations designed decades ago seem outdated. In this article we suggest reassessing foundation payout minimums. To examine the impact of payout rates on grantmaking foundations lifespan and performance under “new normal” economics, we simulate multiple foundations lifecycles using Monte Carlo methods in diverse capital market conditions, with varied investment and payout strategies.We find that while under past market regime perpetuity seems to be a given, under more probable future scenarios, foundations might face increasingly early mortality and endowment depletion, limiting their potential impact. Furthermore, lower payout rates allow for higher lifetime grantmaking, higher mean annual grantmaking, and lower giving volatility. Accordingly, we suggest a tiered payout policy, in line with foundations’ missions and proper financial planning.     

Defending White Scientific Masculinity

While many feminist and postcolonial scholars have analyzed the post-9/11 politic in the United States, few have focused on the anthrax “attacks” that followed the 11 September 2001 World Trade Center disaster. The FBI search for the perpetrator of the 2001 anthrax mailings was an important node in US national security discourse making – it culminated in the fingering of a white male government biodefense scientist and cast doubt on the role of scientific expertise in provisioning national security. This article argues that while “white scientific masculinity” was put into question, it was simultaneously shored up as a nationalist symbol of protection against bioterrorism. This article traces shifts across the three FBI-led profiles of the anthrax perpetrator, along with concomitant news media coverage: the white male “loner” nonscientist, the white male “loner” amateur scientist and finally the white male biodefense scientist. Using a cultural studies approach, this article details how at each successive investigatory stage profilers mobilized hegemonic discourses to re-instantiate the authoritative status of white scientific masculinity in US national security. This analysis offers an important dimension to feminist and postcolonial critiques of the symbolic and institutional investment in white masculinity during the War on Terror.     

思想政治教育有效性的科学内涵及评价依据

对思想政治教育有效性科学内涵和评价标准的正确把握是思想政治教育有效性实现的重要前提。思想政治教育有效性是思想政治教育效果、效益和效率的有机统一。依据思想政治教育效果、效益、效率这三个纬度去把握思想政治教育有效性评价标准。其中从效率的角度来论证思想政治教育有效性的评价标准是本文的独特之处。     

立陶宛《能源法》及其对我国能源立法的启示

我国在能源法治建设方面相对滞后,在《能源法》起草过程中广泛借鉴和合理移植国外先进和有益的立法经验已经成为共识。虽然立陶宛在能源和能源资源状况以及能源产业和能源消费结构方面与我国差异明显,但2002年立陶宛《能源法》在处理能源领域基本法与特别法关系以及若干具体制度方面仍然对我国《能源法》的起草具有一定的借鉴意义。
