S355J2板带表裂的分析与改善

通过对缺陷钢卷理化检验结果的分析以及生产对比试验,指出连铸坯的角部横向裂纹是板带发生表裂的直接原因。并由此分析了板坯角部横向裂纹产生的主要原因。根据实际工艺条件,采取针对性的改善措施后,板卷表裂缺陷得以有效控制。     

增发资格、产权性质与财务特征

以1998—2007年符合增发条件的A股上市公司为研究对象进行实证分析,研究发现公司资产规模越大,资产负债率越低,净资产收益率越大,增发中请越容易获得证监会的批准,而产权性质与上市公司增发申请能否被证监会批准并无显著关系。

浅谈多经企业的发展

伴随着改革开放的春风,各行各业纷纷建立起自己的多经企业,发电企业也不例外。当前随着国家"上大压小"、"节能减排"政策的大力实施,各地纷纷关停中小型火电厂,使得原本依靠主业为主要经济来源的辅业陷入困境,公司管理者虽竭力采用扩大外部市场份额、争取更多发电量、外派、内退等分流手段解决了部分富余人员带来的压力,但是依然会有部分人员会被安排到辅业公司,从而加重辅业负担,使其经营雪上加霜。

Logistics Performance,Customer Satisfaction,and Share of Business: A Comparison of Primary and Secondary Suppliers

The linkage between logistics performance and overall firm performance has received attention in the literature for more than 30 years. However, researchers have not investigated if differences in performance between primary and secondary suppliers affect customer satisfaction and the percentage of business allocated to suppliers. In this research, primary suppliers received more than four times as much business as the secondary suppliers. We investigated the impact of the Marketing Mix on customer satisfaction and share of business for primary suppliers and secondary suppliers, and identified differences between the two groups, using multigroup structural equation modeling. The results indicate that perceived performance on logistics attributes significantly affects customer satisfaction and the percentage of business that is allocated to primary and secondary suppliers, which is key information for developing competitive strategies. Our research findings challenge the practice of providing service levels to customers based on current revenue or profitability which does little to convince customers, who are using a company as secondary source, to make it the primary supplier.     

Transparent Practices: Primary and Secondary Data in Business Ethics Dissertations

We explore the availability and use of data (primary and secondary) in the field of business ethics research. Specifically, we examine an international sample of doctoral dissertations since 1998, categorizing research topics, data collection, and availability of data. Findings suggest that use of only primary data pervades the discipline, despite strong methodological reasons to augment business ethics research with secondary data.     

信用评级机构行为与次贷危机

信用评价机构的正常作用是给次级贷款抵押证券合理的信用评级,从而有利于市场的稳定与发展.由于机制设计的不完善,信用评价机构为了追求自身的物质利益,采用了宽松的评级方式,使信用等级较差的金融衍生产品充斥金融市场,从而引发金融风暴.
