谭恩美的小说《女儿愿》叙述了来自中美不同文化背景的姐妹三人回中国桂林探亲的短暂旅行。运用正 统读法,能了解故事梗概,同时也能认识姐妹间的冲突和矛盾。运用解构式阅读,则瓦解了原来的姐妹“二元对立”的 关系。这说明不同的阅读方法会产生不同的文本意义。  相似文献

We estimate the influence of trade preferences granted by Argentina on the origin of its imports. We try to identify if changes in Argentina's trade policy toward a set of countries had a differential effect, depending on whether goods were already traded, or on the contrary, if tariff changes affected mostly imports of new goods. We distinguish between the effects of changing tariffs and changing trade preferences. The econometric evidence shows that the effect of changes in tariff preferences on the probability of Argentina importing from other Asociación Latinoamericana de Integración (ALADI) members has been rather small, with most of the effect being explained by changes in tariff rates levied on imports from these countries. This result is stronger in the case of imports from Brazil.  相似文献

中国的三元社会结构与城乡一体化发展   总被引:11,自引:0,他引:11  
城乡二元结构同时并存是发展中国家工业化过程中的必然现象,但随着经济的发展,二元结构之间的差距会缩小,并且逐步向着一体化的一元结构转型。然而,改革开放以来,我国的二元结构不但没有弱化,反而有强化的趋势,而且产生了以城市农民工为第三元的三元社会结构,从而对我国经济社会的稳定和健康发展带来不利影响。因此,现在是到了统筹城乡发展、促进结构转型和城乡协调一体化的时候了。而要实现结构的转型,最有现实可能,也是最关键的就是要通过实现国民待遇、降低城市化门槛等途径。首先解决第三元的结构转型问题。  相似文献

企业价值是企业在市场中交易定价的基础,企业在其发展过程中会面临很多投资机会或选择,这些投资机会或选择权是有价值的,然而传统企业价值评估方法仅考虑企业资产现值和未来收益现值,而忽视未来投资时机的最优选择问题。实物期权恰恰是对传统评估方法有益的补充,本文通过对典型实务期权计算模型的应用分析,说明如何利用实物期权模型进行企业价值评估,为企业提供一种新的思路和方法。  相似文献

The purpose of this paper was to test the effect of organizational innovation on product and process innovation (while controlling for endogeneity). Our hypothesis was that organizational innovation should have a significant and positive impact on technical (product or process) innovation. We control for endogeneity by using a Poisson estimator that accommodates a binary endogenous regressor. We test 10 potential instruments using a battery of test criteria and settle on five. All results are presented using the five instruments to avoid expectation bias. In general we find that organizational innovation does impact technical innovation positively. With the 2009 data we find that the mean of the average treatment effect for product innovation is roughly 1.7 times that of process innovation. For the 2009–2012 data we find that the impact on product innovation is roughly 1.5 times that of process innovation. For the 2012 data, we had anomalous results for process innovation, such that organizational innovation reduced the number of process innovations by 2.3 per year. In terms of Canadian government policy, the results lend support to the view that technical innovation is not the only innovation that matters. The right policy mix may encourage firms to experiment with and adopt more organizational innovations to enhance technical innovation.  相似文献

Objective: To compare treatment patterns and economic outcomes of dasatinib and nilotinib as 1st-line therapies for chronic myeloid leukemia (CML).

Methods: Adult CML patients initiated on first-line dasatinib or nilotinib in 2010–2014 were identified from two large US administrative claims databases. Treatment patterns, tyrosine kinase inhibitor (TKI) adherence and healthcare resource utilization (HRU) and costs were measured from the 1st-line TKI initiation (index date) to the end of follow-up.

Results: A total of 604 and 418 patients were included in the dasatinib and nilotinib cohorts (mean ages = 50.9 and 52.5 years, 46.4% and 45.7% female), respectively. Among the dasatinib patients, 91% started with 100?mg/day, 3% with <100?mg/day, and 6% with >100?mg/day. Among the nilotinib patients, 76% started with 600?mg/day, 16% with >600?mg/day, and 8% <600?mg/day. The dasatinib cohort had a higher hazard of dose decrease (hazard ratio [HR]?=?1.66; p?=?.002) and of switching to another TKI (HR =1.62; p?=?.019) compared to the nilotinib cohort. The hazard of dose increase (HR =0.76; p?=?.423) and treatment discontinuation (HR =1.10; p?=?.372) were not significantly different between cohorts. There was also no significant difference in TKI adherence levels (mean proportion of days covered [PDC] difference over first 6 months = ?0.0003, p?=?.981; mean PDC difference over first 12 months = ?0.0022, p?=?.880) and HRU (inpatient day incidence rate ratio [IRR]?=?1.03, p?=?.930; emergency room IRR =1.26, p?=?.197; and days with outpatient services IRR = 1.01, p?=?.842). The dasatinib cohort incurred higher healthcare costs by $749 per patient per month (p?=?.044) compared to the nilotinib cohort.

Limitation: Information on CML phase and Sokal score was not available.

Conclusions: Dasatinib was associated with an increased hazard of dose decrease and switching to another TKI and higher healthcare costs, vs nilotinib.  相似文献

The aim of this article is to analyze the responsibilities of Spanish households, as final consumers, for the generation of domestic greenhouse gases emissions (GHG), by region of residence, distinguishing between NUTS 1 and NUTS 2 (autonomous regions). The motivation is the process of convergence experimented by Spanish regions based on the strong economic growth experienced by the country until 2008, which could results in different emissions responsibilities because of different lifestyles and production structures. We examine in depth the relationships between a representative household in each region and its patterns of consumption. Although we do find a relationship between per capita income and regional responsibility for pollution generation, it is based on a demand scale effect, which overlaps the effects of the regional consumption patterns. Thus, in the richest regions (Madrid, Northeast, East), despite their having a less polluting pattern than other regions, the level of per capita embodied emissions is higher, due to their higher level of consumption. This scale effect, and the linkages between regional responsibilities for emissions and household consumption patterns are analyzed using linear models based on Social Accounting Matrices. The basis of the estimations is the regional emission intensity (average emission per euro spent by each type of regional home).  相似文献
