The contribution of genetics to milk composition: evidence from Spain

This article focuses on the role that genetic progress may play in improving milk quality. Despite important genetic advances in dairy production, the absence of genetic records in farm management databases has precluded empirical production models from explicitly accounting for differences in genetics across herds. The influence of genetics on milk composition is analyzed by splitting milk production into protein, fat, and other components. The article explores some modeling issues associated with the specification of the effect of genetics in this multi‐output technology framework. In particular, genetic indexes are considered as allocable inputs and the remaining inputs as nonallocable. Our results show that genetics have a significant impact on milk composition. In particular, we find that farmers’ income increases by 6.6% when genetic indexes are augmented by one sample standard deviation.     

Factors influencing repeat visits to a destination: The influence of group composition

This paper is an analysis of the likelihood for repeat visits to a sun and sand destination by tourists. For this purpose, an empirical study was conducted using tourists who had visited the destination. The analysis took into account the travelling group composition. The results showed that, for the total tourist sample, overall satisfaction had the biggest influence on the decision of whether to revisit a destination, while the least important influence was the tourist's perceived image. These influences varied, however, when different travelling group compositions were considered. The results are of vital importance in tourism management policies, because they can contribute to the better design and development of tourism promotion strategies.     

Charisma and Compassion – Cheng Yen and the Buddhist Tzu Chi Movement by Huang,C. J.

The authors investigate the relationship between board ethnic diversity, ethnicity and market, and book measures of firm financial performance using Malaysian data. This represents a departure from prior studies that focused on White countries whose people remain culturally indistinct. Ethnic diversity is measured by the Herfindahl-Hirschman Index; ethnicity is the largest representation of a single race. Controlling for firm- and board-specific attributes, the authors find a significant positive relationship between ethnic diversity and firm financial performance and that financial performance of companies differ between ethnicities. The results suggest that despite modernization and homogenization, corporate Malaysia is still divided along racial lines.

社会保障基金投资的外部规定及投资组合

本文研究了各国社会保障基金投资的外部规定和投资组合,并总结出我国可以借鉴的经验;接着本文对我国的相关情况进行分析,结合国外经验,指出我国社会保障基金投资组合的缺陷,提出改进建议。     

我国地区全要素生产率与人力资本构成

考虑到人力资本组成部分的异质性,本文研究了全要素生产率(TFP)与人力资本构成的关系,并运用Dynamic Panel Data一阶差分GMM估计方法对1982—2004年我国28个省区市的面板数据进行了实证检验。实证结果表明,只有接受过高等教育的人力资本部分对TFP才有显著的促进作用。把人力资本分解为不同的组成部分有助于深化我们对TFP和人力资本的理解,还可以使我们对现有文献中人力资本与产出的一些争议提供解释。     

如何提高社会主义意识形态的认同力

中国的社会主义道路在走过六十年历程后,我们的社会主义意识形态面临着信息化、全球化和市场化带来的挑战。对此我们的社会主义意识形态要以实践性为理念,提高人民群众的认同力。首先要实事求是,关注国情;其次要以人为本,团结人民,凝聚力量;最后在舆论宣传方面要疏导互动,形成稳定的社会心理认同。

贸易自由化对环境污染影响的实证分析

采用Panel-data模型方法,研究贸易自由化对环境污染的影响。通过建立联系贸易与环境污染的一般均衡模型,将贸易的环境效应分解为规模效应、结构效应、技术效应,并用我国各省的二氧化硫数据进行检验。结果显示,规模效应加剧我国环境的恶化,而结构效应和技术效应改善我国的污染水平。结论是贸易自由化有利于我国环境保护。     

金沙古史探微

在成都摸底河两岸发现的金沙遗址是历史上开明王朝生活于此的文化遗存。开明族富于治水经验，他们进入成都平原后很快就取代了出自西山的古蜀族．建立了金沙古城．因此这里并无望帝于丛帝禅让的情况。而古蜀族地位逐渐下降．其沦为二等公民殆无疑义。金沙古城与十二桥遗址相近．应是同时代的双子城。金沙时代气候温暖潮湿。其自然环境与三星堆时代迥然不同。距今约2300年前，金沙古城毁于洪水，不久强秦入侵．开明族统治结束．亦即古蜀最后覆亡。
