有效市场假说作为金融经济学的理论基石,无疑是我们研究国际金融市场的重要方法和依据。许多其他得到广泛 应用的金融投资理论皆以此为基础。历经30年的发展,有效市场理论在不断得到支持的同时,也面临了许多新的市场理论的挑 战。混沌理论和分形市场理论,特别是对于市场异象做出新解释的行为金融学,都从不同角度对传统有效市场理论进行了突破。这 不仅为研究国际金融市场提供了新的思路和方法,也对金融市场的决策者和生产者有着巨大的现实意义。  相似文献

Carto-philatelic imagery illustrates that the “mental map” of China underlying territorial policies of the People's Republic of China is constructed, contingent, and impermanent. Although it has claimed Taiwan by asserting primordial sovereignty, declaring the island to have been part of China “since ancient times,” the ruling Chinese Communist Party (CCP) has not always viewed the island as part of China. Although it recognized the independence of Mongolia in 1950, before it came to power as the government of the state the CCP envisioned Mongolia as part of China. Postage stamps issued in territories governed by the CCP before 1949 juxtaposed to stamps issued by the Republic of China government affirm what documents suggest: that China's boundaries have not been immutable and have been highly contested by Chinese political elite. This should prompt readers to view with skepticism categorical claims about China's sovereignty and “territorial integrity.”  相似文献

This study examined the relationship between limited English proficiency status, and internalizing and externalizing behaviors among a sample of Latino/a children (N = 2,840) from the US Department of Education’s Early Childhood Longitudinal Study, Kindergarten (ECLS-K) data set. Results of cross sectional regression and hierarchical linear modeling (HLM) analyses suggest that there is a positive relationship between limited English proficiency and externalizing symptoms, particularly by third grade. Additionally, sex and place of birth also helped to explain externalizing behaviors at various time points in the models. Place of birth and family poverty were significantly associated with internalizing symptoms. Implications for future research and interventions related to internalizing and externalizing behavior among the Latino/a school aged population are discussed.

古代中国与朝鲜的“气”哲学传统比较   总被引:1,自引:0,他引:1  
在中国,元气自然论在王充以后,受魏晋玄学思辩哲学的压抑一度发展低迷,到北宋张载时走向高峰而发展为元气本体论,后又受程朱"理"论的排挤,一度衰微。300年后,王廷相、王夫之的气论又形成发展高潮。在朝鲜,确立气一元论哲学的徐敬德之后,气哲学传统就表现为主理主气之争、唯理唯气之争,最终由崔汉绮总集成。中国的气论主要作为宇宙本根论,道器、形而上、形而下等范畴始终成为诠释的中心。朝鲜的气论则更多地是对心、性、情等伦理本体的探讨,故主要围绕理气、心性、善恶等概念进行了研究。  相似文献

The experience of Soviet involvement in Afghanistan (1979–1989) is considered through the prism of institutional transfers. Afghanistan has a long history of attempts to implement Muslim, Soviet and Anglo-Saxon institutional designs. Most of them have failed. This failure can be attributed to the lack of ‘elective affinity’ between traditional and new institutions imported from more developed countries. It is argued that a careful examination of the degree of elective affinity must precede any attempt of institutional transfers. An analysis of Ph.D. dissertations defended by Afghan students at Soviet and Russian universities complements logical arguments and references to historical facts.

香港民事侵权分为侵犯和非故意干扰两类,对民事侵权的救济可以是法外的,也可以是经过法庭裁定的。在民事侵权诉讼中的被告,可以提出免责理由为其辩护以达到免除责任的目的。可以对香港地区民事侵权的含义、种类、救济手段以及答辩等法律规定予以借鉴。  相似文献

在美国的外交决策中,利益集团有着不可忽视的影响力.冷战后,利益集团更是公开走到了前台,通过游说等手段间接地影响着美国对外政策的制定.为此,中国在处理中美关系时,必须把美国各利益集团因素考虑进去,大力开展第二渠道外交.  相似文献

Non‐state market regulation has become a central focus and continues to receive scholarly attention. The present paper provides an assessment of the conditions under which multinational firms join a multi‐stakeholder certification initiative. The cases of the Fair labor Association and 17 international sport footwear companies have been selected for this purpose. A Qualitative Comparative Analysis of the 17 cases is performed. The paper argues that the combination of sustained NGO pressure and public ownership of a firm is a necessary precondition for firms joining a multi‐stakeholder certification initiative. The theoretical and policy implications of this result are discussed.  相似文献

Violence against the neck can result in a range of macromorphological and micromorphological findings. However, the forensic relevance of the carotid sinus in cases of violence against the neck remains controversial. In this follow-up study of 22 cases of suicidal and accidental strangulations, carotid bifurcations were examined histologically for morphological changes implying direct trauma, including haemorrhage and immunohistochemical expression of heat-shock proteins 27, 60, and 70 and aquaporin-3. These cases were compared with a control group (82 cases) without neck compression or head trauma and with variable causes of death. No relevant histopathological findings implying direct trauma of the carotid bifurcation were found. No cases showed positive aquaporin-3 staining and only five cases showed positive heat-shock protein-27 staining, all of which were hangings. Without massive trauma of the carotid bifurcation, histological alterations cannot be expected. Without signs of rapid death, findings of acute circulatory failure, macromorphological and micromorphological findings of neck compression, and reliable markers indicating relevant impact on the carotid bifurcation the diagnosis of a lethal reflex cannot be verified.

Key points

  • Among 22 cases of strangulation causing death, there were 16 cases of hanging and 6 cases of ligature strangulation
  • Few cases showed small haemorrhages located predominantly in the surrounding fat and connective tissues; however, the haemorrhages did not have any effects on the tissues
  • Neck compression had minimal effects on heat shock protein 27 expression in carotid artery tissue
  • Aquaporin-3 staining suggested it is not a useful marker for relevant neck pressure, or that there had not been any relevant neck impact
  • Our findings suggested no direct evidence for reflex cardiac death resulting from a brief force against the neck
