微生物蛋白硫酸水解提取复合氨基酸的研究

研究了微生物蛋白硫酸水解提取复合氨基酸的工艺条件，采用单因素及正交实验方法，以氨基酸产生量为主要指标，考察水解温度、水解时间、液固比、硫酸浓度等因素对水解氨基酸产生量的影响。实验结果表明，微生物蛋白硫酸水解的最佳条件为：水解温度130℃，水解时间1h，液固比6：1，硫酸溶液浓度50％。在此条件下，氨基酸产生量达到57．191mg／g干菌体。本实验为废水处理过程中产生的微生物蛋白资源化利用提供了理论和实验依据。     

关于"东莞现象"的思考与启示

金融界把东莞在经济金融逆境下获得经济高速增长、金融运行稳定的经济状况称之为“东莞现象”。“东莞现象”的深层原因在于东莞外向型的经济结构和发展模式奠定的基础，也由于东莞金融机构稳健经营的指导思想。“东莞现象”对防范和化解金融风险，维护金融安全提供有益的启示。     

International R&D project evaluation by multinational corporations in the electronics and IT industry of Singapore

This paper explores a number of variables associated with the evaluation of international R&D projects by multinational corporations (MNCs) in the electronics and IT industry of Singapore. Empirical analysis of the data collected from R&D managerial executives suggests a series of considerations in relation to their R&D investments. It is desirable if R&D can create a potential impact on the growth of their regional and international businesses. In considering the risks associated with an R&D project, a balance approach would be appropriate when demanding a return on investment. In particular, the consistence with customer demands, the achievement of time‐based competitiveness, the training of R&D manpower and the development of conducive innovation environments are fundamental to the success of international R&D projects.     

Potentializability and consistency for multi-choice solutions

The paper introduces and discusses several characterizations of the multi-choice Shapley value (introduced by Nouweland et al. in ZOR-Math Methods Oper Res 41:289–311, 1995), on the domain of multi-choice games. These characterizations generalize the potential approach and results of Calvo and Santos (Math Soc Sci 34:175–190, 1997) into this domain, and the relations are treated with the axiomatic approach in Calvo and Santos (Math Soc Sci 40:341–354, 2000). Also, based on the axioms of two-person standardness and consistency, we offer an axiomatization of the multi-choice Shapley value. The authors are grateful to Professor Sjaak Hurkens and the anonymous referees for very helpful suggestions and comments.

如何调动采掘区队积极性 加强高产高效矿井建设

当前．加强高产高效矿井建设是各煤炭企业的必修课。笔者认为．煤炭企业应以创建高产高效采掘区队为突破口，提高创建“双高”矿井建设的水平。重点要从以下几个方面入手：     

对一份价格听证代表名单的分析

价格听证可以使与民生有重大关系的产品和服务的价格更符合社会公众的利益要求,更有利于社会的稳定发展。但就一份武汉市物价局主持的轨道交通票价听证会代表名单进行分析后看,至少在听证代表的构成方面就缺乏足够的公正性和透明度,缺乏对消费者利益的有效保护,消费者在价格博弈中常常处于不利的环境。所以,有关国家机构应该建立一个能较充分反映各方利益的公正的代表机制,适当让处于弱势地位的消费者代表有更充分的发言权和影响力,让供需双方在相对均衡的条件下找到双方利益的契合点,真正实现“公平、公开、公正”原则。

R&D subsidy,intellectual property rights protection,and North–South trade: How good is the TRIPS agreement?

This paper investigates the competition in technology and production between a firm in the North (developed country) and a firm in the South (developing country), and how such competition may be affected by the North’s subsidy on technology improvement and the South’s intellectual property rights (IPR) protection level. It is argued that allowing the North to choose the policy first could bring Pareto improvement. This paper also shows that requiring only the South to tighten its IPR protection (as required by the TRIPS agreement) without putting similar pressure on the North to provide more R&D hurts the South. A more rewarding outcome exists if both the IPR protection level and the technology subsidy rate are chosen optimally. We point out that maximizing world welfare does not consequently hurt the South, or require a tightening of IPR protection in the South.
