Information systems and technology sourcing strategies of e-Retailers for value chain enablement

In the e-Retail industry, a well-designed IT infrastructure is essential in creating a tightly integrated value chain and delivering high quality service. With intense competition for market share and profits, information systems and technology (IST) sourcing decisions are becoming increasingly important to e-Retail firms to support continued growth and market responsiveness. Drawing on the contingency theory, we examine organizational and environmental factors that influence an e-Retailer's IST sourcing strategy of make versus buy in enabling its value chain activities, and we also look at firm-level performance impacts of IST sourcing decisions that involve bundling across value chain activities. We test the proposed model and hypotheses using a panel data set of 307 firms over the period of 2006–2010. The results show that firms that make transformative IT investments tend to source a smaller portion of IST for their e-Retail value chain activities than firms that pursue automate or informate as their strategic role for IT investment. Capabilities are positively associated with IST sourcing. Firms experienced in e-Retail are more likely to build rather than buy their IST. In addition, we find mimicking behavior for IST sourcing among firms in the same merchandizer category. We find that IT strategic role is strongly associated with growth metric, whereas sourcing decisions predominantly impact operational performance measures. There is partial evidence that alignment between IT strategic role and IST sourcing decisions results in better performance effects. Moreover, complementary IST sourcing of synergistic marketing and sales activities positively impacts Web sales and conversion rate, but the sourcing combination of logistics, operations, and sales activities is associated with lower Web sales and conversion rate.     

The role of interpersonal affect in performance appraisal: evidence from two samples – the US and India

The interpersonal affect, a li ke–dislike relationship between a supervisor and his/her subordinate, has traditionally been conceptualized as a source of bias in performance appraisals. However, some researchers have argued that the interpersonal affect may not be a bias, especially where it develops as a result of past performance. In this field study, using data from 190 supervisors in the US, and 113 supervisors in India, we delineate the relationship between interpersonal affect and performance ratings. In both samples, interpersonal affect and performance level were found to have significant effects on performance ratings. Results from the US sample indicated that raters are able to separate their liking for a subordinate from actual performance when a ssigning performance ratings, suggesting that the interpersonal affect does not operate as a bias in the appraisal process. Results from the Indian sample, however, suggest that supervisors inflate ratings of low performers, suggesting that local cultural norms may be operating as a moderator.     

如何运用现代非线性数学方法研究公共交通车辆调度决策系统

时代在进步,经济在腾飞,交通作为经济的命脉,无可质疑的也产生了翻天覆地的变化与发展,但是就目前来看,我国的交通系统由于人口的基数和居民的私家车的增多,交通的压力日趋增大,如何改善这种状况,是本文旨在研究跟探讨的关键所在,本文主要介绍了非线性代数的数学方式来分析和调度交通的车辆,并由此提出了一套利用智能化指导居民出行的优化方案,从而缓解交通压力,提高决策能力,另外,还介绍了一种运用于调度车辆的遗传算法,便于决策者进行参考和配置。     

浅谈提升档案保护工作的策略与措施

档案是历史的真实记录,档案既具有历史性,又具有真实性,它的历史性和真实性是在人们实践活动中自然形成的,同时也是人们实践活动的凭证。档案的历史性和档案的真实性,都是通过一定的物质材料体现出来的,如果这些物质材料老化了,那么档案的历史性和真实性以及它的凭证作用也就不存在了。因此,必须要对档案特别是那些珍贵的和已经有褪化迹象的档案进行安全保护。

沿海 "阴影"城市成因及应对方略——以日照市为例

首先对同一禀赋的50多个沿海城市进行了研究,发现其经济差距非常大;部分沿海城市虽然具有良好的港口、交通、环境等优势条件,但其发展却远不如相邻的周边内陆城市,出现了典型的"阴影"现象.其次,以日照市为例,在挖掘其优势条件与滞后效应矛盾的基础上,深入剖析了制约其发展的各种内外部因素.最后,根据这些制约因素提出了相应的发展策略,以期促使日照市尽快摆脱"阴影"现象.
