石景山制铁所相关数据考

本文通过考证,修正日本侵略者统治石景山制铁所时的三项重要数据。这些数据曾长期被广泛使用,具体为1944年3月发生31812起事故,是由于读错了文献,将当月所有员工的事假统计当作事故来理解;日本统治下的石景山制铁所占石景山地区的土地面积应该是1676228平方米(1.676228平方公里),为有关出版物所述的35000亩(23.331平方公里)的7.18%;石景山制铁所员工最多时是1944年10月,为2.4万人,不是有关出版物所述的5.9万人。     

Bayesian inference for stable Lévy–driven stochastic differential equations with high‐frequency data

In this paper, we consider parametric Bayesian inference for stochastic differential equations driven by a pure‐jump stable Lévy process, which is observed at high frequency. In most cases of practical interest, the likelihood function is not available; hence, we use a quasi‐likelihood and place an associated prior on the unknown parameters. It is shown under regularity conditions that there is a Bernstein–von Mises theorem associated to the posterior. We then develop a Markov chain Monte Carlo algorithm for Bayesian inference, and assisted with theoretical results, we show how to scale Metropolis–Hastings proposals when the frequency of the data grows, in order to prevent the acceptance ratio from going to zero in the large data limit. Our algorithm is presented on numerical examples that help verify our theoretical findings.     

The Complexity of Families Involved in High-Conflict Disputes: A Postseparation Ecological Transactional Framework

The use of the term ‘high conflict’ to describe a wide range of family dynamics after separation and divorce has increased significantly over the years. At the moment, no consensus on the definition of high conflict exists. Lack of definitional clarity hinders the ability for legal and mental health professionals to assess, identify, and effectively intervene with this population. Based on a rapid evidence assessment of 65 empirically based social science studies relevant to high conflict, this article positions high-conflict separation and divorce using an ecological transactional model to better understand risk factors and indicators associated with these families. Authors propose a more comprehensive definition that captures the complexity and interactions of various risk factors and indicators on multiple levels. Positioning high-conflict families using an ecological model identifies several points of intervention professionals can use and the fundamental need for collaboration among stakeholders for effective intervention.     

基于Hawkes因子模型的股价共同跳跃研究

本文首先比较了三种目前主流的共跳检验方法：基于LM检验的共跳检验、BLT共跳检验和FHLL共跳检验,结果表明,三种方法在识别共跳数量上差距明显,但三者结果的重合部分基本属于市场暴涨暴跌行情,说明共跳识别对市场剧烈波动的聚集性较为敏感。基于跳跃、共跳存在的聚集性问题,本文将Hawkes过程引入跳跃和共跳的研究,构建了基于Hawkes过程的因子模型,结果显示,基于Hawkes因子模型的MJ统计量、CJ统计量和实证数据的拟合程度较好,表明因子模型能够更好地描述跳跃和共跳的聚集性。     

基于协调发展度的重大工程团队免疫系统健康评价研究

为评价重大工程团队免疫系统的健康和协调发展状况,本文提出了一种基于协调发展度的评价模型。首先通过文献查询和深度访谈,构建能够体现重大工程团队免疫系统特征的健康评价指标体系;其次利用改进的DEMATEL确定指标权重,然后采用多层次模糊综合评价将相关指标定量化,最终得出重大工程团队免疫系统的健康指数和协调发展度;再次确立重大工程团队免疫系统健康等级和协调发展度划分标准,同时提出免疫系统健康的跟踪评价策略;最后,利用本文模型对某跨国输气管道工程团队的免疫系统进行实证研究。结果表明,协调发展度模型既能反映重大工程团队免疫系统的整体健康程度,又能衡量固有性免疫和适应性免疫的协调发展状况,同时对免疫系统健康的跟踪评价也取得了良好效果。     

网络侵权投诉的平台审核及边界

现行法律规定网络平台侵权投诉（即通知）的形式审查,在机制目的设置上,旨在降低平台实质审查带来的高成本。然而,过于简单的形式审查要件之规定对平台的稳定性与人力审核成本反而提出了更高的要求。为维护平台信息数据的稳定性,平台难免会选择实质审查来减少形式审查所产生的信息波动。这又与网络平台侵权投诉形式审查的宗旨相悖。平台针对不同的权利类型的投诉进行审核,其中最为核心的就是对“构成侵权的初步证明材料”的把握。这个过程是个主观大于客观的自我内心确信。在以高度盖然性为标准的大前提下,网络平台要做的是权利归属的恰当性判断。     

以职业性为导向的全日制专业学位研究生培养模式研究

全日制专业学位研究生培养是对学术学位研究生培养的一种互补,更是职业性导向的强烈需求。当前,师资队伍、课程体系、培养目标、教学方法、教学内容等方面存在突出问题,阻碍了专业学位教育的健康发展。全日制专业学位研究生的培养,要以职业性为导向,明确专业学位教育定位,打造高质量的师资、创新教学内容与教学手段,构建模块化教学体系,并进行职业资格认证,以此保障专业学位研究生的质量与良性发展。     

从跨文化交际语境看日本人的交际模式

从跨文化交际语境出发,根据语境文化对交际模式的影响,探讨日本高语境文化形成的原因,分析在高语境文化影响下日本人以和为贵、集团主义意识强、以心传心的体察式的交际模式,对于提高人文素养,减少跨文化交际中的误解,促进交流都将有着重要的意义。     

Is High Sexual Desire a Risk for Women’s Relationship and Sexual Well-Being?

Historically, women’s sexual desire has been deemed socially problematic. The growing popularity of the concept of hypersexuality—which lists high sexual desire among its core components—poses a risk of re-pathologizing female sexual desire. Data from a 2014 online survey of 2,599 Croatian women aged 18–60 years was used to examine whether high sexual desire is detrimental to women’s relationship and sexual well-being. Based on the highest scores on an indicator of sexual desire, 178 women were classified in the high sexual desire (HSD) group; women who scored higher than one standard deviation above the Hypersexual Disorder Screening Inventory mean were categorized in the hypersexuality (HYP) group (n = 239). Fifty-seven women met the classification criteria for both groups (HYP&HSD). Compared to other groups, the HSD was the most sexually active group. Compared to controls, the HYP and HYP&HSD groups—but not the HSD group—reported significantly more negative consequences associated with their sexuality. Compared to the HYP group, women with HSD reported better sexual function, higher sexual satisfaction, and lower odds of negative behavioral consequences. The findings suggest that, at least among women, hypersexuality should not be conflated with high sexual desire and frequent sexual activity.     

Differential predictors of academic achievement: individual and familial factor interactions with community poverty

We present an analysis of the contexts within which adolescents graduate from high school and enroll in college. Data from the National Longitudinal Study of Adolescent Health show that adolescents’ school engagement, maternal academic monitoring, and community poverty significantly interact to explain differences in high school graduation and college enrollment rates (n?=?7100). To examine this association, we performed weighted logistic regression analyses, controlling for gender, race, block level unemployment, and block level median income. Findings suggest that protective factors can help youth overcome the challenges associated with community poverty and achieve academically in low and medium levels of poverty, but that youth in high-poverty contexts may need more resources to reach higher levels of academic attainment.
