In this article we consider the Double Eleven shopping festival as a major discursive site where the hegemony of what we call patriarchal capitalism with Chinese characteristics is articulated. The state, the market, the corporations and the media, both mainstream and social media, all played an important role in building up a national spending spree that is deeply embedded in the current class and gender structure of China. The phenomenon of Double Eleven emerged at a time when state capitalism has been overwriting socialist institutions, while patriarchal ideology being further intensified through consumerism. As a consequence, the intersectionality of class and gender becomes increasingly manifest in the Chinese society. We start with a brief overview of the trajectory of gender politics in China since 1949, with specific focus on how the socialist project of seeking gender equality was gradually replaced by the quest for ‘womanhood’ and ‘femininity’. We then discuss, using both secondary sources and our own analysis of news coverage of Double Eleven, why maintaining a high level of consumer demand is of crucial importance for the Chinese state and what the state’s role has been in configuring the hegemonic gender order. A brief section on ideology and discourse lays out the conceptual framework of our analysis. It is at the intersection of a dissipating socialist ethos, emerging economic stagnation and ascending consumerism that the sexist discourse in relation to Double Eleven proliferates, and this is the analytical focus of our empirical section. We elaborate on the theoretical implications of the empirical analysis before concluding. 相似文献

Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along urban gradients in these regions. Bird communities across a gradient of nine sites in Uganda, from the city centre of Kampala to outlying rural locations, were studied over a six year period. These sites were ordered along an urbanization gradient using Principle Components Analysis based on habitat variables estimated at each site. Bird species richness showed a decrease from rural to urban sites, a trend especially evident in forest birds. There was no clear pattern in total abundance, total biomass or biomass per individual along the gradient. However, this latter result was heavily influenced by a colony of Marabou Storks at one site. When this species was omitted, there was evidence of a positive trend with urbanization, showing that as species richness decreased, the bird community was increasingly dominated by larger species with increasing urbanization, which were mainly scavengers able to exploit human refuse. These results provide further support for the negative impacts of urbanization on species richness, but also demonstrate trends in abundance and biomass are variable across different regions. In particular, the increasing dominance of larger species in urban areas may be relevant to certain geographic and/or socioeconomic contexts. 相似文献

This paper addresses the collinearity problems in semi-parametric linear models. Under the difference-based settings, we introduce a new diagnostic, the difference-based variance inflation factor (DVIF), for detecting the presence of multicollinearity in semi-parametric models. The DVIF is then used to device a difference-based matrix perturbation method for solving the problem. The electricities distribution data set is analyzed, and numerical evidences validate the effectiveness of the proposed method. 相似文献

We examine inferences about old-age mortality that arise when researchers use survey data matched to death records. We show that even small rates of failure to match respondents can lead to substantial bias in the measurement of mortality rates at older ages. This type of measurement error is consequential for three strands in the demographic literature: (1) the deceleration in mortality rates at old ages; (2) the black-white mortality crossover; and (3) the relatively low rate of old-age mortality among Hispanics, often called the “Hispanic paradox.” Using the National Longitudinal Survey of Older Men matched to death records in both the U.S. Vital Statistics system and the Social Security Death Index, we demonstrate that even small rates of missing mortality matching plausibly lead to an appearance of mortality deceleration when none exists and can generate a spurious black-white mortality crossover. We confirm these findings using data from the National Health Interview Survey matched to the U.S. Vital Statistics system, a data set known as the “gold standard” (Cowper et al. 2002) for estimating age-specific mortality. Moreover, with these data, we show that the Hispanic paradox is also plausibly explained by a similar undercount. 相似文献

Problem
Rates of medical interventions in childbirth have greatly increased in the Western world.Background
Women’s attitudes affect their birth choices.Aim
To assess women’s attitudes towards the medicalization of childbirth and their associations with women’s background as well as their fear of birth and planned and unplanned modes of birth.Methods
This longitudinal observational study included 836 parous woman recruited at women’s health centres and natural birth communities in Israel. All women filled in questionnaires about attitudes towards the medicalization of childbirth, fear of birth, and planned birth choices. Women at <28 weeks gestation when filling in the questionnaire were asked to fill in a second one at ~34 weeks. Phone follow-up was conducted ~6 weeks postpartum to assess actual mode of birth.Findings
Attitudes towards medicalization were more positive among younger and less educated women, those who emigrated from the former Soviet Union, and those with a more complicated obstetric background. Baseline attitudes did not differ by parity yet became less positive throughout pregnancy only for primiparae. More positive attitudes were related to greater fear of birth. The attitudes were significantly associated with planned birth choices and predicted emergency caesareans and instrumental births.Discussion
Women form attitudes towards the medicalization of childbirth which may still be open to change during the first pregnancy. More favourable attitudes are related to more medical modes of birth, planned and unplanned.Conclusion
Understanding women’s views of childbirth medicalization may be key to understanding their choices and how they affect labour and birth. 相似文献106.

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?0.01). After adjusting for age and testosterone level, abnormal blood pressure (BP) was the most significantly independent component of MtS for kidney stone among the MtS components (p?0.01, OR?=?2.81, 95% CI: 1.46–5.39).Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone. 相似文献

This paper examines contemporary developments among Taiwan’s indigenous Austronesian peoples. We have reviewed major policy changes mainly since the 1980s and their impacts on later developments – both the positive improvements in general well-being and the persistence of ingrained problems among them. Major findings indicate two growing trends among Taiwanese Austronesians. One is the rise of interest in their cultures and efforts to preserve and restore selected indigenous customs and practices. The other trend is a continuous outflow of the indigenes from traditional tribal communities to urban centers for better employment, education, or health care. Their increasing urbanization also contributes to more inter-ethnic marriages and the loss of indigenous languages and practices. The case of Taiwanese Austronesians illustrates the impacts historical and politico-economic processes are having on indigenous peoples. 相似文献
