A proposed model of online consumer behavior: Assessing the role of gender

This research examined the influence of Internet experience and web atmospherics on consumer online behavior. It developed a model of web navigation behavior where these antecedent variables drove website exploratory behavior and website involvement, which in turn, drove site attitudes and pre-purchase evaluations. These relationships were tested and confirmed in the context of a pharmaceutical website. Further, men and women differed in web navigation behavior, with men engaging in less exploratory behavior and developing less website involvement than women. However, across the two sexes, entertainment, challenge, and effectiveness of information content were the key drivers of website attitudes. The findings provide several guidelines for online communication strategy.

超市常见含糖食品中糖含量分析

目的:分析超市含糖饮料的含糖量及种类情况。方法:在人流量大的综合超市,按照随机原则,购买74种含糖饮料,并采用离子交换色谱-脉冲安培积分方法检测各类糖分的含量。结果:各类饮料在葡萄糖、乳糖、果糖、麦芽糖、蔗糖以及总含糖量方面比较均具有统计学差异(P<0.05),总糖含量最高的为咖啡,其次为奶茶,总糖含量最少的为茶饮料。结论:各类含糖饮料在含糖种类和含量方面有所不同,咖啡与奶茶的总含糖量较高。     

米粉滚筒干燥工艺的优化

在单因素试验的基础上,确定以滚筒蒸汽压力、滚筒转速和料膜厚度为3个主要因素,以成膜率、色泽和水分含量为响应值,采用响应面法设计优化滚筒干燥工艺参数。结果表明:米粉滚筒干燥工艺最优参数为:滚筒蒸汽压力0.45 MPa、滚筒转速3.5 r·min-1、料膜厚度0.2 mm。验证结果与理论值接近,说明所得工艺参数准确可靠,可用于实际生产操作。

Internationalization of Chinese and Korean firms

This article compares and contrasts the growth of Chinese and Korean multinational enterprises (MNEs). The article identifies the similarities and differences between Chinese and Korean MNEs in terms of motivations for internationalization, expansion strategies, and paths. The goal of this article is to contribute to the literature by shifting focus on host‐country conditions to home‐country conditions in explaining the drivers for firms' internationalization. We conclude that firms are motivated to expand abroad when faced with domestic competitive disadvantages resulting from absence or deficiency of one or more of Porter's Diamond attributes in their domestic market. Implications for further studies are also explored. © 2009 Wiley Periodicals, Inc.     

Fruits Proves Confidence
