In 1219 an encounter took place between a Christian from Italy, Francis of Assisi, and the Muslim Sultan of Egypt, al-Malik al-Kāmil. This meeting took place at Damietta in northern Egypt during the progress of the Fifth Crusade. Over a period of perhaps three weeks, religious dialogue took place between Francis and al-Kāmil, after which time the Sultan had Francis escorted safely back to the Christian camp. It is possible to discern from the writings of Francis after his return from Egypt that the meeting had had a deep religious impact upon him, realised in the latter years of his life. It can be said that both Francis and al-Kāmil experienced through their encounter what the Christian theologian Bernard Lonergan has spoken of as a conversion into a new horizon. The historical encounter between Francis and the Sultan witnesses to the fact that through religious conversion, it is possible for members of different religious faiths to arrive at a common vision of universal peace and reconciliation. 相似文献

为研究同时进行爆发力训练与有氧耐力训练所产生的效果,本研究以14名耐力运动员为实验组(E)、14名耐力运动员为控制组(C)进12周的训练,实验组除15%爆发力训练代替传统耐力训练外,其余训练内容相同。结果发现:5 km跑成绩与RE在实验组明显提高(P<0.05),控制组无差异;5 J在实验组有非常显著性提高(P<0.01),控制组下降显著(P<0.05);VO2max在控制组显著性提高(P<0.01),对实验组变化不明显。混合控制组与实验组数据发现:5km跑时间与RE存在中度负相关(r=-0.54)。结论:同时进行爆发力与耐力训练在不改变VO2max的情况下可以提高5 km跑的成绩。 相似文献

This paper addresses the role that scientific status plays in initial public offerings of technology focused firms. The paper builds on the literature of the sociology of science as well as the work of Spence (1974) and Podolny (1993) and argues that the presence of a Nobel laureate affiliated with a firm making an IPO provides a signal of firm quality to potential investors. Moreover, and building on the work of Podolny and Scott Morton (1999) and Stuart et al. (1999) we hypothesize that the importance of status diminishes as other measures of firm quality become available. We test our hypothesis for two periods of initial public offerings in biotechnology. We document that there is a clear difference in “maturity” of the firms across the two windows on a number of metrics. Consistent with our hypothesis that Nobel laureates play an important role as a non-financial signal of firm quality, we find that first-window firms with a Nobel laureate affiliate realize greater IPO proceeds in the amount of $24 million. In the second window the amount of money raised is not significantly different between Nobel and non-Nobel firms. This finding is consistent with the signaling literature that argues that the importance of a signal is inversely related to the availability of cogent information on firm quality. Consistent with this view, we also find a change between the two windows in the importance of other non-financial metrics used to convey value. Our research is one of the first to examine the dynamic nature of signals. Because we are unable to distinguish the extent to which the reduction in uncertainty at the firm level is correlated with the reduction of uncertainty at the industry level, the question remains as to the extent to which the diminished importance of signals in our second period is due to a change in market uncertainty versus a change in firm uncertainty. 相似文献

基于技术采用生命周期研究中的技术“峡谷”概念及特征,以及“峡谷”跨越的相关理论,对通过官方统计及问卷调查获取的数据进行分析,论证我国3G技术在目前的市场应用过程中正面临着“峡谷”跨越问题,并通过对3G技术潜在使用者的心理特征的分析,说明他们与“峡谷”对岸的消费者——实用主义者相一致,跨越3G技术“峡谷”的关键是找准实用主义者心理特征的影响因素并制定相应策略,在此基础上为电信企业提出了对策建议,以期为3G技术的市场发展提供参考借鉴。 相似文献

H指数和G指数在专利权人评价中的实证研究——以电通信中“数字信息的传输”技术为例 总被引:1,自引:0,他引:1
专利,作为集技术情报、经济情报、商业情报等于一体的知识载体,在分析高技术企业的技术水平方面有重要的作用。在前人将H指数应用于专利权人分析的基础上,进一步将G指数移植到专利权人的评价中,并对源于德温特专利数据库的2001-2010年的电通信技术中的数字信息的传输中的相关专利权人,进行了比较。通过专利量、H指数和G指数的分析,本文发现日、韩和我国的部分企业在专利量方面有优异的表现,然而在H指数和G指数所显示的技术实力方面,却远不如美国、欧洲的高科技企业。 相似文献

Methionine synthase reductase (MTRR) is an important enzyme of the folate/homocysteine pathway. It is responsible for regulation of methionine enzyme by reductive methylation. A common variant A66G is reported in the FMN-binding domain of the MTRR gene, which leads to substitution of isoleucine by methionine (I22M) in MTRR enzyme with reduced activity. Reduced catalytic activity of enzyme leads to high homocysteine concentration in blood and increases risk for numerous diseases. The frequency of A66G polymorphism varies in different ethnic groups. The present study has been designed to evaluate the frequency of MTRR A66G gene polymorphism in the Eastern UP population by PCR–RFLP method. Along with this we also performed a meta-analysis to evaluate the global prevalence of this polymorphism. Databases were screened to identified the eligible studies. The prevalence of the G allele and GG genotype was determined by the use of prevalence proportion with 95% CI. Open meta-analyst software was used for the meta-analysis. Total 1000 blood samples were analyzed, the frequencies of A and G alleles were 0.35 and 0.65 respectively. Meta-analysis results revealed that the prevalence of G allele and GG genotype were 49.4% (95% CI 40.6–58.1, p ≤ 0.001) and 24.3% (95% CI 17.8–30.9, p ≤ 0.001) respectively. In sub-group meta-analysis, the lowest frequency of G allele was found in South America (32.7%; 95% CI 14.1–51.3, p ≤ 0.001), and highest in Asia (56.4%; 95% CI 39.5–73.3, p ≤ 0.001). The results of the meta-analysis showed that the Asian population has the highest frequency of G allele and highest frequency of the GG genotype was found in the European population. 相似文献
