在各种主客观因素的作用下,人民币汇率制度改革应运而生,这一汇率变化必将对中国的社会和经济带来巨大的影响。近年来,我国的船舶出口业发展喜人,在国际市场上拥有很强的竞争力,并有着继续壮大的趋势,但随着人民币升值的影响以及船舶出口业的特点,决定了船舶出口业必定要受到较大的冲击和影响。所以在整个贸易大环境下,船舶出口业只有清楚地认识到人民币升值带来的影响,才能正确把握船舶出口的前进方向,运用有效的措施来巩固并促进船舶出口业的发展。 相似文献

本文分析了中国近 5年来外贸出口增长速度及外贸出口效益的变化趋势 ,并用“增长型衰退”对其加以表述 ;一个国家的外贸出口难于做到线型增长 ,但中国的外贸出口增长速度下滑 ,却跟外贸出口的外延增长方式以及出口商品结构变化缓慢有关。通过创新以提升出口商品结构 ,是我国外贸出口走可持续发展的必由之路 相似文献

In this paper we investigate the asymptotic critical value behaviour of certain multiple decision procedures as e.g. simultaneous confidence intervals and simultaneous as well as stepwise multiple test procedures. Supposing that n hypotheses or parameters of interest are under consideration we investigate the critical value behaviour when n increases. More specifically, we answer e.g. the question by which amount the lengths of confidence intervals increase when an additional parameter is added to the statistical analysis. Furthermore, critical values of different multiple decision procedures as for instance step-down and step-up procedures will be compared. Some general theoretic results are derived and applied for various distributions. 相似文献

Regarding the devastating aftermath of divorce among Iranian divorced women, which is mainly affected by sociocultural factors, this qualitative study was conducted to explore their applied strategies in reorganizing their lives. Data collection started through deep unstructured interviews followed by semistructured interviews with 18 divorced women who were chosen by purposive sampling from mental health clinics, social work centers, or available cases. Gathered data were analyzed using the qualitative content analysis method. Two main themes—behaviors of self-preservation and abstinence and struggling for balance—emerged. Subcategories were concealing the divorce, feminine self-restriction, avoidance behaviors, replacement of losses, seeking support, role development, handling the tensions, and defending oneself against the divorce failure. This study provides comprehensive knowledge of how Iranian divorced women reregulate their lives and also highlights their unique and culture-based coping strategies. Therefore, it provides specialists with a context-specific foundation for mental health care and enables them to intervene more effectively. 相似文献

The Rowlands Parental Alienation Scale (RPAS) was administered to 592 parents along with measures of convergent and discriminant validity. The scale was designed to capture the eight domains of parental alienating behavior posited in the literature. Factor analysis extracted only six factors, one of which was not included in the original eight: (a) campaign of denigration towards the alienated parent, (b) the independent thinker phenomenon, (c) reflexive support, (d) presence of borrowed scenarios, (e) spread of animosity to extended family, and (f) lack of positive affect towards the alienated parent. Parents who reported either that a court evaluation or court findings had confirmed the presence of parental alienation scored significantly higher on all six RPAS factors as well as on the overall RPAS score. 相似文献

In the current research, we aimed to identify the reasons that could drive people to get a divorce. In Study 1, we employed qualitative research methods, and we identified 62 reasons that could potentially drive people to get a divorce. Using quantitative research methods, in Study 2 we classified these reasons into 7 broader factors. We found that being a harmful spouse was the most important factor for divorce, followed by incompatibility and in-law problems. We also found significant sex differences in several factors such as women indicating a higher willingness than men to divorce a harmful spouse. In addition, participants with children were less willing to divorce a harmful spouse than those who had no children. Finally, using second-order principal components analysis, we classified the 7 factors into 2 broader domains of reasons for getting a divorce. 相似文献

A smoothed bootstrap method is presented for the purpose of bandwidth selection in nonparametric hazard rate estimation for iid data. In this context, two new bootstrap bandwidth selectors are established based on the exact expression of the bootstrap version of the mean integrated squared error of some approximations of the kernel hazard rate estimator. This is very useful since Monte Carlo approximation is no longer needed for the implementation of the two bootstrap selectors. A simulation study is carried out in order to show the empirical performance of the new bootstrap bandwidths and to compare them with other existing selectors. The methods are illustrated by applying them to a diabetes data set. 相似文献

This paper presents a simple and robust method for obtaining a comprehensive understanding of the joint period and radius distribution in Kepler exoplanets. The proposed method is based on particle swarm optimization and bivariate Normal Inverse Gaussian distribution. Furthermore, in the construction of the probability density function, this study selects planet-host stars with the GK-type. The injecting approach is also employed to solve the survey completeness of sample. The resulting occurrence rate of Earth analogs is 0.025 with a 95% bootstrap confidence interval between 0.023 and 0.032. 相似文献
