Groups Formation and Operations in the Web 2.0 Environment and Social Networks

The Internet and the Web are evolving to a platform for collaboration, sharing, innovation and user-created content—the so-called Web 2.0 environment. This environment includes social and business networks, and it is influencing what people do on the Web and intranets, individually and in groups. This paper describes the Web 2.0 environment, its tools, applications, characteristics. It also describes various types of online groups, especially social networks, and how they operate in the Web 2.0 environment. Of special interest is the way organization members communicate and collaborate mainly via wikis and blogs. In addition, the paper includes a proposed triad relational model (Technology–People–Community) of social/work life on the Internet. Particularly, social/work groups are becoming sustainable because of the incentives for participants to connect and network with other users. A discussion of group dynamics that is based on the human needs for trust, support, and sharing, regardless if the setting is a physical or virtual one, follows. Finally, future research directions are outlined.

The effects of rational and habitual factors on mode choice behaviors in a motorcycle-dependent region: Evidence from Taiwan

This paper aims to explore the effects of rational and habitual factors on mode choice behaviors in a motorcycle-dependent region. Both a discrete choice model and theory of planned behavior (TPB) are employed to examine mode choice behaviors. A sample was obtained from two major cities in Taiwan to examine the contextual effect of public transport development. The empirical results reveal that psychological (rational and habitual) factors have stronger influences on mode choice behaviors than socio-economic factors, and furthermore that habitual factors explain traveler mode choice behaviors better than rational ones. The contextual effect with regard to public transport development is found to be significant for motorcyclists' mode choice behaviors. The practical implications of the results of this study are discussed.     

口服液中粗多糖提取方法的改进

为了考察改进苯酚-硫酸法测定保健品口服液中粗多糖提取方法的可行性,以某保健品口服液为样品,对采用苯酚-硫酸法测定粗多糖含量时的多糖的不同提取条件与测定进行一个较为详细、系统的研究。结果表明:样品经改进提取条件后测定,试验结果表明有良好的线性关系,精密度RSD值为0.69%,稳定性良好,平均加标回收率为101.0%。该方法改进后提高了该实验的精密度和准确度,重现性高,并使结果更加可靠和稳定。     

Location,Marketing, and the Financial Flexibility of Nonprofit Performing Arts Organizations in Second Tier Cities

This article examines the effect of location relative to other marketing factors on the financial flexibility of nonprofit performing arts organizations (PAOs). While product development and promotional and pricing strategies are important marketing factors, locational advantages have become an important strategic asset for the arts industry. Yet very little research has been done on the locational dimensions of this industry. Based on a survey of PAOs in six second tier U.S. statistical metropolitan areas (SMAs), that is, Buffalo, Pittsburgh, Cleveland, Columbus, Cincinnati, and Milwaukee, this article investigates the extent to which location and other marketing mix factors influence the financial flexibility, and thereby success of PAOs. All six SMAs have a population range of 1 million to 2.5 million. The statistical analysis suggests that location and product selection are particularly significant marketing mix factors that contribute positively to financial flexibility, and therefore organizational success of the PAOs in the cities.
