Citizenship awarding is politicised. Conceiving female marriage migration as a national threat, Taiwan's citizenship legislation is consciously designed and purposefully utilised to achieve exclusion and assimilation. Driven by a nationalistic impetus, it shows how Taiwan imagines itself as a modern, prosperous and homogenous nation and projects upon the immigrant outsiders as a threat to its self-identity. Examined through immigrant women's lived experiences, this citizenship legislation is biased by gender, class and ethnicity. The implementation of the legislation is not only an example of symbolic politics but also banal nationalism realised at grassroots level in the private domain. Immigrant women's lived experiences show that exclusion and assimilation stemmed from banal nationalism is not just an operation of symbolic politics but is also enmeshed with their everyday life.  相似文献

Sustainability standards are flooding global agricultural markets. Standards, however, are not new. This article analyses, from a historical perspective, the implications of the transition from traditional to sustainability standards in the commoditisation/de‐commoditisation process. It shows how early standards contributed to the construction of the category of primary commodities and how, after a short attempt at de‐commoditisation (with the early fair‐trade and organic standards), sustainability standards are tending towards re‐commoditisation.  相似文献

Endogenous entry in auctions with negative externalities   总被引:1,自引:1,他引:0  
In this paper, we study the auction to allocate an indivisible good when each potential buyer has a private and independent valuation for the item and suffers a negative externality if a competitor acquires it. In that case, the outside option of each buyer is mechanism-dependent, which implies that participation is endogenous. As several works in the literature have shown, the optimal auction entails strong threats to induce full entry and maximal expected revenue. This results from the full commitment assumption, which ensures that threats are credible. We show that absent credible threats, the entry process does not lead to full participation: the equilibrium entails screening of agents in the entry stage and a trade-off between reserve prices and entry fees. Besides, we discuss the conditions under which the impossibility to use threats does not prevent the seller from ensuring a minimal screening and reaching a high expected revenue.  相似文献

The ability of the randomized response technique to obtain sensitiveinformation on surveys was compared to two other methods involvingself-administered questionnaires. Using a national probabilitysample, and extending upon a number of developmental changeswhich have evolved over the years, the randomized response techniqueproved to be decidedly superior to the other methods.  相似文献

This paper outlines some of the main findings from an exploratory study of a sample of 257 adolescents living in children's homes, foster homes and residential special schools ‘for pupils with emotional and behavioural difficulties’ (‘EBD’). It focuses on the characteristics of service users, particularly contrasting the looked after and EBD groups. Though there are some similarities, there are also important differences between the populations in terms of age, gender, ethnicity, reasons for separation, legal status, family background and education. An attempt was made systematically to compare groups by creating a subsample of ‘difficult’ adolescents, based on involvement in anti‐social behaviour. Unexpectedly, this revealed that half of the teenagers were not ‘difficult’. Factors associated with being identified as ‘difficult’ were explored.  相似文献

It is unclear whether long-term aerobic (AT) or resistance (RT) training can improve insulin sensitivity (IS) beyond the residual effect of the last training bout in older women (54-78 years). Therefore, a group of nonobese, healthy older women underwent 6 months of AT (n = 8) or RT (n = 10), and the authors measured IS 4 days after the last training bouts using the hyperinsulinemic-euglycemic clamp technique. Women trained 3 days/week. AT consisted of 25- to 60-min sessions of walking/jogging at 60-95% of maximal heart rate. RT consisted of three sets of nine exercises repeated 10 times at 80% of 1 repetition maximum. AT decreased fat mass, whereas both AT and RT increased fat-free mass. Neither training program, however, improved absolute or relative rates of glucose disposal. The authors therefore concluded that nonobese, healthy older women should perform AT or RT on a daily basis in order to improve IS and maintain the improvement.  相似文献

Low back pain is a costly and incapacitating musculoskeletal disorder. Prospective studies documenting the capacity of work-related factors to predict chronicity are few in number, the methodology used is very diversified, and the results obtained diverge. The aim of the present study is to investigate the capacity of work-related objective (non-psychosocial) and psychosocial factors to predict chronic disability related to low back pain. A longitudinal prospective study with two measurement times was carried out. The sample (N = 258) consisted of workers with subacute low back pain who were on sick leave and receiving compensation from the CSST (Quebec Workers' Compensation Board). Of all the work-related variables measured, perceived stress and fears and beliefs about work were associated with return to work status at the six-month follow-up. The results obtained show the importance of considering fears and beliefs about work when identifying people in the subacute phase of low back pain who are at risk of developing chronic disability.  相似文献

Facial expressions of fear and disgust have repeatedly been found to be less well recognized than those of other basic emotions by children. We undertook two studies in which we investigated the recognition and visual discrimination of these expressions in school-age children. In Study 1, children (5, 6, 9, and 10 years of age) were shown pairs of facial expressions, and asked to tell which one depicted a target emotion. The results indicated that accuracy in 9- and 10-year-olds was higher than in 5- and 6-year-olds for three contrasts: disgust–anger, fear–surprise, and fear–sadness. Younger children had more difficulty recognizing disgust when it was presented along with anger, and in recognizing fear when it was presented along with surprise. In Study 2, children (5, 6, 9, and 10 years of age) were shown a target expression along with two other expressions, and were asked to point to the expression that was the most similar to the target. Contrary to our expectations, even 5- and 6-year-olds were very accurate in discriminating fear and disgust from the other emotions, suggesting that visual perception was not the main limiting factor for the recognition of these emotions in school-age children.  相似文献

This paper studies the nonparametric identification of the first‐price auction model with risk averse bidders within the private value paradigm. First, we show that the benchmark model is nonindentified from observed bids. We also derive the restrictions imposed by the model on observables and show that these restrictions are weak. Second, we establish the nonparametric identification of the bidders' utility function under exclusion restrictions. Our primary exclusion restriction takes the form of an exogenous bidders' participation, leading to a latent distribution of private values that is independent of the number of bidders. The key idea is to exploit the property that the bid distribution varies with the number of bidders while the private value distribution does not. We then extend these results to endogenous bidders' participation when the exclusion restriction takes the form of instruments that do not affect the bidders' private value distribution. Though derived for a benchmark model, our results extend to more general cases such as a binding reserve price, affiliated private values, and asymmetric bidders. Last, possible estimation methods are proposed.  相似文献

以西安市28岁以上的大龄未婚男性流动人口为研究对象,进行了性行为相关内容的电子问卷调查,并收集农村大龄未婚男性进入城市后可能产生的风险性行为信息;通过分析明确了大龄未婚男性流动人口的风险性行为概况和人群特征,用逻辑斯蒂(Logistic)回归模型探析了其行为现状与影响因素。研究发现,大龄未婚男性流动人口在多个性伴侣与商业性行为表现出明显倾向;大龄未婚男性流动人口的经济条件年龄以及受教育程度对其风险性行为产生了影响;周围人群的风险性行为参与对大龄未婚男性流动人口的风险性行为参与产生带动作用;此外,无保护性行为在这一人群中的比例已经显著降低。  相似文献
