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。     

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”.     

国内外广告产业统计范围的比较

广告产业统计为广告产业发展的基础性研究课题,同时是政府进行广告产业的财政统计的依据与标准以及实现国际相同产业发展对照的基本标准.我国现行的广告产业统计标准多年来未经调整修正,不能真实反映产业发展实际.文章通过综述国内外相关学术研究,并结合我国现行的《广告业统计报表制度(2012)》、《国民经济行业分类(GB/T4754-2011)》、联合国颁布的《所有经济活动之国际标准行业分类(修订4版)》与《北美产业分类体系(2012)》当中广告产业的统计分类与统计范围,总结我国现行的广告产业统计分类标准存在的主要问题,即产业界定、定位与广告产业现实发展偏离;产业分类方式滞后;产业统计范围狭窄且有重合之处.     

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.     

Who is Jobless? A Comparison of Joblessness in Rural and Urban Areas in China

Since market‐oriented economic reform was launched in China in the 1980s, unemployment has been recognized by the government. This paper focuses on the differences in joblessness in rural and urban areas between rural migrant workers, peasants, and urban citizens. The results indicate that people in rural areas frequently lose their jobs, which differs from the traditional perception. There is a significantly lower jobless rate in urban areas. In contrast to the results of previous studies, the employment situation of rural migrant workers is closer to urban citizens rather than peasants. Logistic regression results show that the elderly, women, and less educated citizens have a higher likelihood of joblessness, both in urban and rural areas. Minorities have a lower likelihood of joblessness in rural areas and a higher likelihood in urban areas. Chinese Communist Party members and people without dependent children have a lower likelihood of joblessness in urban areas.     

Who needs Cantonese,who speaks? Whispers across mountains,delta, and waterfronts

This essay digs into the ‘dirtiness’ of cultural studies to prioritize praxis, or as the way my mountain folks collect summer lotus: putting our feet in the muddy water, and finding ways to get the stems underneath the smooth leaves. Using Cantoneseness as a case to locate such ‘dirtiness’, I draw on personal/familial histories as well as research projects to tell how conjunctures of Cantoneseness are politically and unevenly lived. This complex journey travels roughly from my childhood in the Yuebei mountains of northern Guangdong through my teenage and early adult years in the Pearl River Delta (PRD) to my current location as a temporary resident in the East Pacific port of Vancouver. I selectively emphasize and speak on three different locations: first, the rural inland Cantonese location of Yuebei mountains – the borderland and hinterland experiences of my family and myself living what the mountains would offer and how these have changed; second, the industrial superior Cantonese location of PRD in Shenzhen and Guangzhou – my personal experiences and identities as a migrant youth, combined with a case study including interviews with migrant peasant-workers and their children; and third, the western transnational Cantonese location of East Pacific waterfronts in Vancouver and Richmond – my personal engagement with social activism as an ethnicized, international student, combined with a narrative study including interviews with social activists with different Cantoneseness and migration routes. While this mix of whispers speaks in its own way towards using cultural studies with more seriously (global) space-sensitive and (social justice) praxis-sensitive approaches, the primary focus is more modestly on my autobiographical accounts and research efforts as a specific case: to show some strategic locations of ‘Cantonescape’ on the one hand, and to invite wider conversations around cultural-spatial politics on the other.     

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.
