严复的海军理论素养与实践能力

严复1871年以优异成绩毕业于船政学堂,随后一直在练船实习服役,成为一名优秀管驾官;1877年留学英国皇家海军学院,专业成绩优异,并业余研究西方社会科学;1878年因专业成绩优异而非体质不适合上舰而被确定为教习人选。严复归国后长期担任天津水师学堂"总教习",用英语教授与航海有关的数学、天文、地理等课程,而非单纯教授"洋文",更非因专业知识不足而只能教"洋文"。     

董必武法制思想探析

强调法制是董必武思想理论体系的一个重要组成部分 ,即 :突出以人民代表大会制度为核心的民主建政思想 ;明确政法工作应促进经济建设的法制服务思想 ;强调有法可依、有法必依的依法治国思想。这些观点至今对我们进一步加强民主法制建设具有启迪作用和现实意义。     

Non-parametric quantile estimate for length-biased and right-censored data with competing risks

In this article, we propose a non-parametric quantile inference procedure for cause-specific failure probabilities to estimate the lifetime distribution of length-biased and right-censored data with competing risks. We also derive the asymptotic properties of the proposed estimators of the quantile function. Furthermore, the results are used to construct confidence intervals and bands for the quantile function. Simulation studies are conducted to illustrate the method and theory, and an application to an unemployment data is presented.     

变压器经济运行的研究

随着电力工业的迅速发展,变压器经济运行越来越引起人们的关注。变压器经济运行与众多因素有关,本文仅从设计、制造、运行等方面探讨变压器的经济运行。首先讨论变压器损耗特性的非线性对变压器经济运行的影响,变压器技术特性与经济运行之间的关联。同时对变压器容量、变压器并联台数的选择,变压器更新时机及方式的选择等技术经济问题展开讨论。     

Parent Conflict as a Mediator Between Marianismo Beliefs and Depressive Symptoms for Mexican American College Women

Abstract

Objective: The purpose of this study is to examine how marianismo is related to the depressive symptoms of Mexican American women with family conflict as a mediator. Participants: During January of 2010, 170 Mexican American women college students in a southern, Hispanic-serving institution were sampled. Methods: A mediation analysis was conducted to determine if parent conflict mediates the relationship between marianismo values and depressive symptoms. Results: Results from Barron and Kenny's¹ mediation analysis method, in conjunction with a Sobel² test indicated that parent conflict significantly mediated the relation between marianismo and depressive symptoms. Conclusion: Findings and implications of the mediation will be discussed for the mental health and treatment of Mexican American women college students.     

中西医学话语与近代商业——以《申报》上的“痧药水”为例

痧药在晚清大量出现,随着药水的剂型出现,其被运用的范围也愈来愈广。痧药水不但是中西医皆爱用的商品,且常常成为慈善家施药和展开卫生运动时的赠品,它可以治疗霍乱、中暑或以上吐下泻为主要疾病的肠胃炎。在社会广泛运用和中西医不断解释、报纸广告的介绍下,它还变成了近代最有名的治疫、防疫药品,而且有许多例子是病人自己诊断、自己用药,缺乏专业医者的诊断,此模式成为近代防疫史中一段非常有趣的故事。中西医者也针对痧药水的疗效和成分进行各种解读和论述,上层医者与下层民众对药品与疾病认识上的异同,近代媒体推进药品社会化的深度,说明近代中西医药品的宣传、销售以及对疾病的解释等使得"痧药水"在社会中渐渐被塑造成能广泛治疗、防范各种"时疫"的药品。     

民国学人的学术史研究

民国时期,我国学术史研究的范式和领域较之清代大有扩展,既出现了梁启超、钱穆等学术史家,也涌现出了一大批优秀成果.民国时期是我国学术史研究的承前启后、贯通中西的重要阶段.但由于时代的局限,学术史研究也受到了一定的制约.总结民国时期学术史研究的得失,将有助于我们更好地弘扬学术史研究的优良传统和促进新时代学术的发展.     

重申儒家“使民”思想──关于“民可使由之”章的最新解释

近年来,有些学者利用考古发现的郭店楚墓竹简中的儒家文献,对《论语》中的“民可使由之,不可使知之”一章做了新的探讨,提出了新的解释。这些解释可以分别称为“强制说”、“身教说”与“反智说”。他们对于探讨孔子这一条语录的确切含义做出了各自的努力。但是这些解释都存在着不同的问题。将郭店楚墓竹简《尊德义》等儒家文献的内容,同孔子的思想进行比较,完全可以进一步证实本文作者于１９９４年提出的“使民说”的解释的正确性。     

食品安全报道的传媒责任——“老酸奶”事件中的媒体呈现及其反思

由名人微博爆料引发的“老酸奶”事件,由于涉及整个社会极为关注的食品安全话题,经过作为新媒体典型代表的微博的广泛传播和传统媒体的推波助澜,一时间引发公众广泛议论,几近酿成公共危机事件.然而,由于始终未得到证实或证伪,成为一起少见的有始无终的传播事件.媒体应该反思在这起事件中的呈现,提升食品安全报道的“净化力”,强化食品安全报道能力,实现食品安全报道的日常化,以提升公众对于突发食品安全事件的风险感知与辨别能力.     

Classification Algorithm for Skin Color (CASCo): A new tool to measure skin color in social science research

Objective

A growing body of literature reveals that skin color has significant effects on people's income, health, education, and employment. However, the ways in which skin color has been measured in empirical research have been criticized for being inaccurate, if not subjective and biased.

Objective

Introduce an objective, automatic, accessible and customizable Classification Algorithm for Skin Color (CASCo).

Methods

We review the methods traditionally used to measure skin color (verbal scales, visual aids or color palettes, photo elicitation, spectrometers and image-based algorithms), noting their shortcomings. We highlight the need for a different tool to measure skin color

Results

We present CASCo, a (social researcher-friendly) Python library that uses face detection, skin segmentation and k-means clustering algorithms to determine the skin tone category of portraits.

Conclusion

After assessing the merits and shortcomings of all the methods available, we argue CASCo is well equipped to overcome most challenges and objections posed against its alternatives. While acknowledging its limitations, we contend that CASCo should complement researchers. toolkit in this area.
