劳动力市场的城乡分割意味着经济效率的损失,一直来备受关注。本文构建了一个劳动力市场城乡分割指数,基于中国城镇住户调查浙江省的数据,测量了城镇劳动力市场城乡分割的程度。结果显示:在工资回报层面,相对高端领域的分割程度弱于相对低端领域,但在就业机会层面,相对高端领域的分割程度强于相对低端领域。为此我们建议:劳动力市场管理上重点关注低端劳动力市场中城乡劳动者的同工同酬问题,公共政策设计上重点关注高端劳动力市场中城乡劳动力的平等就业机会问题。 相似文献

In many diagnostic studies, multiple diagnostic tests are performed on each subject or multiple disease markers are available. Commonly, the information should be combined to improve the diagnostic accuracy. We consider the problem of comparing the discriminatory abilities between two groups of biomarkers. Specifically, this article focuses on confidence interval estimation of the difference between paired AUCs based on optimally combined markers under the assumption of multivariate normality. Simulation studies demonstrate that the proposed generalized variable approach provides confidence intervals with satisfying coverage probabilities at finite sample sizes. The proposed method can also easily provide P-values for hypothesis testing. Application to analysis of a subset of data from a study on coronary heart disease illustrates the utility of the method in practice. 相似文献

汉语写作如何造就了少数民族的优秀作品——以鄂温克族作家乌热尔图的作品为例 总被引:3,自引:0,他引:3
论文以鄂温克族作家乌热尔图的作品为例,揭示汉语写作怎样成就了少数民族优秀文学作品三个方面的独特价值.1.融文人创作和民间故事、传说蕴涵丰富的神话母题素及民歌为一体,为文学史家和民间文学研究提供了一种特殊的叙事性文本形态.2.汉语平台上民族文学中所描写的神话及民间传说、习俗地理特征等地方性知识得到了文学性表现,形成了各民族神话的比较机制及诗性智慧的再发现和启示.3.汉语写作的民族文学作品具有特殊的文化认同意义,民族文化身份认同表现为双重性和动态性.他留给我们的思考在于:在汉语写作平台上,民族作家如何才能在坚守民族身份特征的基础上,坚守作家的艺术生命? 相似文献

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. 相似文献

AbstractAs a worldwide cultural phenomenon, contemporary art in China has not only been used as a diplomatic language but also a reflection of contemporary Chinese culture. Contemporary Chinese art, as an emerging field to display China’s global role, provides an important perspective to study China’s self-position in global relations, China’s diplomacy in exercising its soft power, contemporary Chinese culture, and the reinvention of China’s cultural/national identity in post-Mao China. Using the 2000 Shanghai Biennale and the Chinese pavilion at the 54th Venice Biennale as case studies, this article investigates how the fluid construct of Chineseness is successfully promoted and demonstrated through the government’s support of contemporary Chinese art. 相似文献

Unified Inference for Sparse and Dense Longitudinal Data in Time‐varying Coefficient Models

Time‐varying coefficient models are widely used in longitudinal data analysis. These models allow the effects of predictors on response to vary over time. In this article, we consider a mixed‐effects time‐varying coefficient model to account for the within subject correlation for longitudinal data. We show that when kernel smoothing is used to estimate the smooth functions in time‐varying coefficient models for sparse or dense longitudinal data, the asymptotic results of these two situations are essentially different. Therefore, a subjective choice between the sparse and dense cases might lead to erroneous conclusions for statistical inference. In order to solve this problem, we establish a unified self‐normalized central limit theorem, based on which a unified inference is proposed without deciding whether the data are sparse or dense. The effectiveness of the proposed unified inference is demonstrated through a simulation study and an analysis of Baltimore MACS data. 相似文献

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. 相似文献
