This study examines the causal relationship between popularity information and purchasing behavior in an online store. In a randomized field experiment we exogenously manipulated the visibility of user-generated content similar to Google’s +1s or Facebook’s Likes. Displaying the number of people who “Like” a product caused a +12.97% sales increase (13,883.74 EUR in the treatment group; 12,289.4...

Object-oriented case representations require approaches for similarity assessment that allow to compare two differently structured objects, in particular, objects belonging to different object classes. Currently, such similarity measures are developed more or less in an ad-hoc fashion. It is mostly unclear, how the structure of an object-oriented case model, e.g., the class hierarchy, influence...

The advancement of digital technologies is driving traditional product oriented businesses to move from selling product to selling solutions. In order to exploit business potentials from technology, it is necessary to understand the technological capacity and how it influences the value creation in the environment where it is deployed. I study remote diagnostics as an example of digital technol...

The information systems literatur calls for two major shifts in IS management: from DP leadership to line management leadership and from a task-oriented approach to a processoriented approach. Despite the widespread interest in these matters, few empirical studies have dealt with these issues. This paper reports on two exploratory studies which set out to examine use and management of IS in sel...

Russia's economic transition in the past decade from a centrally-planned to a market-oriented economy has occurred within a dramatically changing political, social, and cultural context. The biggest shift occurred in late 1991, when more than seven decades of communist rule came to a swift end, the former U.S.S.R. was dissolved, and Russia started on a new course toward a more democratic politi...

The reasons that people play on-line games is an important area of research. This study views on-line games as entertainment technology. However, while most past studies have focused on task-oriented technology, pr...

Cognitive linguists contend that learners’ awareness of motivations is the key in not only second language acquisition but also figurative language learning. Two cognitive-oriented methods are proposed to raise L2 learners’ awareness on metaphoric/metonymic expressions and to enhance retention: instruction involving conceptual metaphors (CM) and instruction involving metaphoric mappings (MM). T...

In this chapter, we discuss how culture influences computer mediated communication (CMC). We use an Input-Process-Output (I-P-O) model as a theoretical framework to analyze relationships between culture and CMC. We describe three dimensions of cultural variability—individualism/collectivism, low vs. high context of communication, and taskvs. relationship-orientation—and describe how these dimen...

Using a sample of Korean American elders, this study examined internal mechanisms by which the level of acculturation influences mental health outcomes. We hypothesized that the impact of five domains of acculturation on mental distress (depressive symptoms and anxiety) would be mediated by individuals' subjectively appraised acculturative stress. The latter was indexed by measures of task-orie...
