我国丝绸出口贸易的 "显示"比较优势指数呈逐年下降的趋势,但其数值一直保持在17以上,说明我国的丝绸出口与其他出口商品相比仍具有很大的竞争优势;我国丝绸出口的相对价格弹性系数为-0.3825,属于低弹性的商品.降低丝绸出口价格,不但无益于丝绸出口量的增加,反而会引起出口创汇额的明显下降,引起丝绸"出口贫困"现象的产生.稳定我国丝绸出口价格,是我国蚕丝业和丝绸贸易稳定发展的正确选择. 相似文献

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition
of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness. 相似文献

The residential and social segregation of whites from blacks creates a socialization process we refer to as “white habitus.” This white habitus limits whites' chances for developing meaningful relationships with blacks and other minorities spatially and psychologically. Using data from the 1997 Survey of College Students' Social Attitudes and the 1998 Detroit Area Study, we show that the spatial segregation experienced by whites from blacks fosters segregated lifestyles and leads them to develop positive views about themselves and negative views about blacks. First, we document the high levels of whites' residential and social segregation. Next, we examine how whites interpret their own self‐segregation. Finally, we examine how whites' segregation shapes their racial expressions, attitudes, cognitions, and even their sense of aesthetics as illustrated by their views on the subject of interracial marriage. 相似文献

In this paper we introduce a new three-parameter exponential-type distribution. The new distribution is quite flexible and can be used effectively in modeling survival data and reliability problems. It can have constant, decreasing, increasing, upside-down bathtub and bathtub-shaped hazard rate functions. It also generalizes some well-known distributions. We discuss maximum likelihood estimation of the model parameters for complete sample and for censored sample. Additionally, we formulate a new cure rate survival model by assuming that the number of competing causes of the event of interest has the Poisson distribution and the time to this event follows the proposed distribution. Maximum likelihood estimation of the model parameters of the new cure rate survival model is discussed for complete sample and censored sample. Two applications to real data are provided to illustrate the flexibility of the new model in practice. 相似文献

In the past decade, growing public concern about novel technologies with uncertain potential long‐term impacts on the environment and human health has moved risk policies toward a more precautionary approach. Focusing on mobile telephony, the effects of precautionary information on risk perception were analyzed. A pooled multinational experimental study based on a 5 × 2 × 2 factorial design was conducted in nine countries. The first factor refers to whether or not information on different types of precautionary measures was present, the second factor to the framing of the precautionary information, and the third factor to the order in which cell phones and base stations were rated by the study participants. The data analysis on the country level indicates different effects. The main hypothesis that informing about precautionary measures results in increased risk perceptions found only partial support in the data. The effects are weaker, both in terms of the effect size and the frequency of significant effects, across the various precautionary information formats used in the experiment. Nevertheless, our findings do not support the assumption that informing people about implemented precautionary measures will decrease public concerns. 相似文献

通过对近年来我国出现的通货紧缩现象的分析 ,可以看到中央银行所采取的稳健的货币政策的内容及其执行状况。经济的不景气不是由于货币供应量不足而是在于货币政策的传导机制的不畅。我们应找出传导机制不畅的原因 ,并提出相应的对策 相似文献

The ongoing debate over the flaws in the nation's welfare system centers primarily on two highly charged social ills: teen-age pregnancy and long-term dependence on public assistance. For the poorest and fastest growing segment of the welfare population—homeless mothers—these problems are both severe and inextricably linked. At an alarmingly young age, these women are becoming trapped in a chaotic cycle that offers little structure and few alternatives. 相似文献

Gender, home and family in cultural capital theory 总被引:1,自引:0,他引:1
Silva EB 《The British journal of sociology》2005,56(1):83-103
The paper argues that Bourdieu's stress on early familiarization for the highest value of cultural capital is closely linked to his idea, strongly emphasized in Distinction, about the role of family and domestic life for individual development and social positions. The role of women, as mothers and homemakers, is crucial in this process. Yet, Bourdieu defines social origin as deriving from the father. The centrality to Bourdieu's thinking of a resilient traditional pattern of masculine domination and feminine submission constitutive of the Western gender habitus explains both his stress on ‘normalcy’ for the production of legitimate dispositions, and his resistance to incorporating into his thinking the implications of recent transformations in home family living, which have destabilized the gender order. It is thus important to consider contemporary feminist analyses of the family and home life and their significance for a renewed theory of cultural capital. The paper considers two sets of literature. Firstly, it addresses the manners in which home and family are conceptualized in Bourdieu's key texts where these issues were prominent in the development of his thinking on cultural capital. The second set of literature includes texts by feminist academics in the fields of family, gender and the body, which analyse the destabilizing of the gender order and everyday family living in contemporary society. Two questions are addressed on the basis of these reflections: (1) Is cultural capital an individual or a household resource? (2) How does cultural capital relate to personal interdependencies at the level of family and households? 相似文献
