The advent of Web2.0 has believed to be the solution against many barriers in information sharing, especially wiki. Information sharing and collaboration are realized voluntarily and unselfishly with wiki. The purpose of this paper is to analyze the benefits and challenges of using wiki as a project management method in an IT/IS project. Wiki-based project management could provide project managers and members with expert knowledge collaboration for better project results. In the research model, we used TMS(Transactive Memory System) theory to define the relation of collaboration and performance of project members. Based on a survey among project members, the interactions between wiki characteristics and performance are examined in an IS project environment. Using Smart PLS 2.0, the data was analyzed to define the interactions by the structural equation modeling. From the empirical data, the mediated effect of expert knowledge collaboration is supported. We also derive the implications of wiki-based method. It is expected to bring new possibilities of Project management performance.

This article reports that a testee's content schemata have detrimental effects on the validity of standardized reading comprehension tests. in case that the reading passages constitute his prior background knowledge framed by regular academic pursuits focused on a major field of study. The empirical research findings on such a reliability issue have shown that the Korean subjects' familiarity with the content domain of the reading materials may substantially enhance their test performance, operated as unfair advantages over the other participants at the same level of English proficiency who do not possess technical knowledge closely related to the contents of the test passages. Based on these results, it may be argued that the reading text should be composed of maximally neutral contents to every testee to avoid the possible overlapping between a test-taker's content schemata and the content domain of the materials. Therefore, this article claims that the tenets of schema theory with its long-standing foundation on culturally predetermined content and formal schemata need to be expanded to cover professional knowledge structures, like those acquired by higher education, as the hard-wired framework of an individual's original culture-specific background knowledge.

The social capital of an organization is recognized as the origin of the knowledge capital creation, and it becomes the mechanisms which explain the interaction of members or which accelerate the behavior of the members to attain the goal of an organization (Park, 2001; Jang et al., 2011). Lots of researches show that this causal relationship empirically exists. Social capital and knowledge capital of an organization are one of the most important competitive advantages that a company needs. They are also the main dynamic drivers of the innovation activity. This study analyzes the relationship and examines the impact and role of an organization's social capital on intellectual capital and innovation activities in an organization. In other words, the main purpose of this study is to analyze the impact of social capital on the intellectual capital and innovation activities of, in particular, China local companies. This study empirically analyzed the survey data collected from the employees of the companies located in China. Our empirical results of this study showed that social capital has significantly causal effects on intellectual capital partially and also showed the intellectual capital has significantly positive effects on the innovation activities partially.

Recently, with the increasing popularity of smartphones, mobile applications have been being used in various sectors. In these environments, some mobile applications are being made for special purposes. The mobile campus application is one exemplary type of such special-purpose mobile applications, which have unique characteristics that allow only designated users, belonging to a specific group, to access and use relevant knowledge. The aim of this study is to identify and investigate critical success factors of mobile campus applications based on the DeLone & McLean's information systems (IS) success model and to find unique characteristics of mobile campus applications, compared to general-purpose mobile applications. In order to empirically test our research model, 199 samples were collected from students who actually had experience of using the mobile campus application of A university at least once. The findings of the structural equation modeling using SmartPLS 2.0 confirmed the DeLone & McLean's IS success model, with the exception for relationships between service quality and user satisfaction/intention to use. Moreover, the moderating role of sense of belonging to school on the relationships between quality-related factors (i.e., information, system, and service qualities) and success-related factors (i.e., user satisfaction and intention to use) was examined.

From old times, companies have created profits by developing business models utilizing their friendship with customers, so the relationships can be connected to the activity giving a gift. This activity of giving a gift is developed as the service of giving gifts via social network services (SNS) as the use of SNS and smart phones is recently increased in relation to that, this study set the online friendship desire and the SNS gift convenience as the intrinsic motive and the extrinsic motive of the SNS gift behavior, respectively. This study identified how the interactivity's sub factors influenced on the online friendship desire/SNS gift convenience by reorganizing the interactivity's sub factors in the mobile context. As the results of this study, it was found that the connectedness, the synchronicity and playfulness positively influenced on the online friendship desire for the SNS gift convenience, the only connectedness positively influenced on it. And it was identified that the SNS gift convenience and the online friendship desire positively influenced on the SNS gift intention. This study is academically meaningful in that it conducted an empirical research by focusing on the friendship desire in relation to the SNS gift. Besides, through the results of this study, the online friendship desire and the SNS gift convenience will have to be considered as providing any SNS gift service, and that is expected to create knowledge for SNS business model to companies.

As the digital retail environement becomes prevalent, consumers are given greater opportunities to make purchases across physical and digital boundaries. Prior research emphasizes that the attractiveness of the digital or online channel is relatively determined by spatial specifics of physical locations. The overall market trend combined with prior research suggests that understanding spatial specifics becomes a key to managing both offline and online sales performance together. In this study, we focus on geographic variation in sales performance through offline and online channels and aim to investigate the channel-level sales difference between central and subsidiary areas. To this end, we obtain sales data of skincare and makeup products from a leading cosmetic company. Next, we examine spatial autocorrelations in data and then employ the spatial error models to study the effects of spatial specifics. The empirical findings are as follows. First, there are significant differences in category-specific and channel-level sales between central and subsidiary areas. Second, Moran's I statistics demonstrate the spatial autocorrelations of each variable. Third, spatial error models outperform simple regression models with lower AIC values. Finally, spatial specifics play a greater role in understanding online sales in subsidiary areas whereas they exert greater influence on offline sales in central areas. We believe our study advances the related theory and knowledge of multi-channel retailing and also contributes practically to location-dependent multi-channel strategies and sales data analytics.
