梁启超群治文学观初探

梁启超是中国近代文化转型过程中最具代表性的人物。20世纪初期,梁启超引进西方文化观念,首倡近代多种文体的革新,提出了著名的"群治社会构想",反映在文学思想上主要包括四个方面,即聚合现代民族精神,展示历史进化趋势,"言文一致"语体风格和构建市民文化空间。梁启超"群治"文学观的提出及其有益实践对启蒙国人思想、推进中国文学发展和社会进步,都具有重要意义。     

亚洲服务业:发展与创新——“第四届现代服务业发展论坛”综述

国际金融危机爆发以来,亚洲各国一直面临着较为严峻的外部环境,而健康发展的服务业是亚洲经济特别是亚洲发展中国家经济保持增长的关键所在。在此背景下,由浙江树人大学、浙江省现代服务业研究中心共同主办的"第四届现代服务业发展论坛",于2014年11月7日在浙江树人大学隆重举行。会议围绕"亚洲服务业:发展与创新"主题,在亚洲区域服务经济发展战略、亚洲区域经济合作视域下我国服务业开放问题、亚洲各地服务业行业创新发展等方面展开了多角度、多层面、系统深刻的讨论和交流,提出了许多创新的观点,为亚洲服务业持续健康发展提供了很多理论上、实证上与政策上的支撑。     

社会价值视角下的音乐教育改革

音乐伴随社会发展不断变化,成为社会文化构成的重要元素。目前我国音乐教育的现状令人堪忧:轻视对学生进行音乐教育,学生的音乐素质普遍不高,音乐教育资源分布很不均衡,音乐师资水平低,音乐教学设施落后。教育主管部门应积极倡导先进音乐文化的传播,发挥音乐的社会价值和精神引导作用。要创造良好的音乐教育环境,完善音乐教育的必要设施。

Testing homogeneity in semiparametric mixture case–control models

Parametric and semiparametric mixture models have been widely used in applications from many areas, and it is often of interest to test the homogeneity in these models. However, hypothesis testing is non standard due to the fact that several regularity conditions do not hold under the null hypothesis. We consider a semiparametric mixture case–control model, in the sense that the density ratio of two distributions is assumed to be of an exponential form, while the baseline density is unspecified. This model was first considered by Qin and Liang (2011 Qin, J., Liang, K.Y. (2011). Hypothesis testing in a mixture case–control model. Biometrics 67(1):182–198.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], biometrics), and they proposed a modified score statistic for testing homogeneity. In this article, we consider alternative testing procedures based on supremum statistics, which could improve power against certain types of alternatives. We demonstrate the connection and comparison among the proposed and existing approaches. In addition, we provide a unified theoretical justification of the supremum test and other existing test statistics from an empirical likelihood perspective. The finite-sample performance of the supremum test statistics was evaluated in simulation studies.     

异质性产品质量与出口加成率

相对于已有研究分析生产率、目的市场选择和市场竞争等因素对出口加成率影响的视角,本文采用2000-2007年企业层面数据测算了28个细分制造业出口产品质量指数及按照会计方法处理的出口加成率,对中国制造业行业产品质量与出口价格加成率的关系进行实证分析.研究结果表明:出口加成率总体并没有随产品质量而提升,但影响因产品质量的异质性而存在差异,劳动密集型制造业出口产品质量显著提高了加成率,而技术和资本密集型产业仍处于阶段性“加成率陷阱”.     

中国—东盟自贸区“升级版”背景下中泰水果贸易发展的优化建议

基于中泰两国地缘差异性及资源禀赋互补优势,双边水果贸易合作发展取得了令人瞩目的成效,贸易总量持续增长,贸易地位日益凸显,成为两国经贸合作的重要内容.中泰水果贸易合作中仍存在着:水果种类单一、深精加工有限、附加值较低、互补优势尚未充分挖掘、贸易便利化水平不高、国际与地区竞争激烈等突出问题.在打造中国—东盟自贸区“升级版”新形势下,中泰两国应充分立足互补性优势,构建水果商品贸易信息合作平台,增强宣传与培育特色品牌,完善运输渠道与减低物流费用,挖掘国内潜在市场,促进双边水果贸易合作取得更大的成效.     

The impact of age,BMI and sex hormone on aging males’ symptoms and the international index of erectile function scores

Objective: To analyze the impact of age, BMI and sex hormone on aging males’ symptoms (AMS) and the 5-item version of the international index of erectile function (IIEF-5) scores in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County. A total of 969 men, aged between 40 and 80 years old, were admitted. Physical examination and the sex hormones were measured, and AMS and IIEF-5 scores were assessed.

Results: The oneway ANOVA analysis indicated older age groups had higher AMS total-scores, somatic and sexual sub-scores, and lower IIEF5 scores (all p?r_pairwise) analyses showed the significant associations between AMS and age or sex hormone (cFT, Bio-T, SHBG, and LH) levels, and similar for IIEF5. However, when age was adjusted, the correlation coefficients (r_partial) weakened, and correlation significance disappeared, except LH (for AMS: r_partial?=?0.096, p?=?.009; for IIEF-5: r_partial?= ?0.140, p?=?.001). Multiple linear regressions confirmed the influence of increased age and LH on the AMS and IIEF5 scores.

Conclusion: CFT, Bio-T and SHBG failed to yield any additional predicting information when age was adjusted. To improve the male reproductive health, future research should pay more attention on aging-related comorbidities and how to improve general wellness.     

基于多源遥感的城市生态用地识别及生态风险评价

随着城市化进程的不断推进、建设用地不断扩张,城市生态空间正处于剧烈变化中。大量具有生态价值和服务功能的土地不断被侵占,以满足暂时的城市建设需求。但从长远来看,这些生态用地的"消失",将不可避免的影响区域生态平衡,给区域经济的健康发展埋下隐患。广州作为华南的中心城市,改革开放以来,大量外来人口涌入,土地利用变化频繁,生态环境的保护面临着巨大压力。因此,本文基于多源遥感数据,利用监督分类法与综合指数法相综合的复合提取方案对2016年广州生态用地进行空间识别,掌握广州市生态用地存量现状。同时,借助生态风险小区和生态风险等景观指数对广州进行了生态风险评估,结果显示,广州市生态风险呈现明显的多核圈层结构,由多核心的中心向外部逐渐降低。     

Stereotype and National Attachment in Hong Kong Chinese Context: A Moderated Mediation Model of Perceived Inter-group Relationship and Age

The present study investigated the relationship between Hong Kong people’s stereotype toward Mainland people and their own national attachment (i.e., national identity, constructive patriotism, and uncritical patriotism). The role of inter-group relationship as mediator and age as moderator of that relationship were also tested. A total of 1753 local Hong Kong people aged 17–80 (mean age = 20.35 years, SD = 5.02) completed anonymous questionnaires regarding their stereotypes toward Mainland people, inter-group relationship with Mainland people, and national attachment. As expected, stereotypes toward Mainland people, inter-group relationship and national attachment showed significant positive associations with each other. More interestingly, it was found that the inter-group relationship mediated the relationship between stereotypes toward Mainland people and three domains of national attachment, with this indirect link being weaker for younger Hong Kong adults than for older Hong Kong adults. Implications of the present findings for future research are discussed, as well as potential interventions for increasing subjective national attachment to China, especially in young Hong Kong people.
