论个人资信评估体系的构建主体

结合其他国家建立信用体系的经验及我国进行信征集试点城市的现状来分析以政府牵头为主，金融机构先行为主及第三方自发为主的三个构建主体方案的利弊，最终得出一个适合中国国情的、合理的、高效的个人资信体系构建主体。     

反商业贿赂与政府采购机制的完善

政府采购已成为财政支出的重要组成部分.巨大的利润空间给政府采购带来了商业贿赂的风险.运用成本-收益理论、政府规制俘获理论和公平理论,分析其产生的根源及可能带来的后果,可采取相应措施消除政府采购中商业贿赂因子的现实途径.     

个人教育投资的均衡分析

人力资本投资的关键形式是教育投资。文章认为,个人教育投资的均衡条件是边际成本等于边际收益。因为个人教育投资的边际成本递增,边际收益递减,所以必须采取多种措施刺激个人教育投资的积极性,才能促进我国教育事业的大发展。     

对发展我国汽车金融公司的思考

随着我国加入WTO以后对汽车金融服务业的进一步开放,国外汽车金融公司纷纷进驻这个极具潜力的庞大市场.2003年底我国先后颁布了<汽车金融公司管理办法>和<汽车金融公司管理细则>,至2005年1月,通用、大众、丰田汽车金融(中国)公司相继开业.本文在介绍成熟汽车金融公司特点的基础上,针对我国汽车金融公司的具体情况,提出一些对策与建议,希望能够对我国的汽车金融公司的发展有所裨益.

解读新一轮改革的逻辑

"十八大"以后,中国进入新一轮改革时期。新一轮改革是一场问题导向式改革,新时期所出现的诸如经济增长乏力、效率低下、市场秩序混乱等新问题是新一轮改革的逻辑起点,放、激、管三管齐下是解决新问题的主要方式。新一轮改革的目标是处理好政府与市场的关系,而理顺政府与市场关系的关键在于充分发挥市场在资源配置中的决定性作用,通过市场发力形成中国经济增长的内生力,探索出一条具有中国特色的市场经济道路,这条道路就是中国模式。     

Multi-product capacitated facility location problem with general production and building costs

This research introduces the multi-product capacitated facility location problem with general production and building costs (MP-CFLPGC). The MP-CFLPGC extends previous problems found in the literature by including multiple products and general production and building cost functions that allow the modeling of different behaviors like economies of scale and congestion. The MP-CFLPGC is formulated as a mixed integer linear program (MILP). To evaluate the performance of the proposed formulation we analyze the results of a commercial optimizer on a set of 288 randomly generated test instances that resemble the Colombian cement industry supply chain. After one hour the optimizer achieved an optimality gap of 1.0 % or less in 55 % out of the 288 test instances. On average the optimality gap was 3.57 %. Additionally, we propose a randomized mathematical-programming-based heuristic for the test instances where the MILP formulation presents significantly high optimality gaps.     

Inflation targeting credibility and sovereign risk: evidence from Colombia

This article relates to the literature on sovereign risk in developing countries. In particular, we present empirical evidence to address the effect of inflation targeting credibility on sovereign risk based on the Colombian experience. The findings denote that credibility is an important improvement in the institutional framework to reduce the sovereign risk premium.     

The relationship between high performance work systems and employee proactive behaviour: role breadth self‐efficacy and flexible role orientation as mediating mechanisms

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.     

粮食中镉含量测定方法初探:以石墨炉原子吸收分光光度计法为例

笔者长期从事粮食中镉污染检验工作,大量实践经验表明,虽然原子吸收仪的品牌、型号各不相同,但应用原理、结构大致相同。本文以石墨炉原子吸收分光光度计法对粮食中镉的含量的检测为例进行说明,发现试样前处理、试剂空白、使用试剂、回收实验及在操作过程中的对仪器的处理等对检测结果均会产生直接影响。为确保检测结果准确性,本文对检测过程中影响检测结果的各注意事项进行了分析总结,希望能对从事镉污染检测工作的人员提供理论指导和借鉴。
