This study was aimed at examining the diffusion of diagnostic lung cancer tests in Germany. It was motivated by the high potential of detecting and targeting oncogenic drivers. Recognizing that the diffusion of diagnostic tests is a conditio sine qua non for the success of personalized lung cancer therapies, this study analyzed the diffusion of epidermal growth factor receptor (EGFR) and anapla...

In this paper we describe how a statistical test on a hypothesis regarding collaborative math problem solving using online chats showed an unexpected result, whose understanding required the use of qualitative methods. The phenomenon behind the result is identified using Conversation Analysis. This paper demonstrates the importance of using qualitative methods to describe the perspective of par...

This work studies online scheduling algorithms for buffer management, develops new algorithms, and analyzes their performances. Packets arrive at a release time r, with a non-negative weight w and an integer deadline d. At each time step, at most one packet is scheduled. The modified greedy (MG) algorithm is 1.618-competitive for the objective of maximizing the sum of weights of packets sent, a...

Introduction: The medical literature has identified a variety of health risks associated with travel. Risks depend on the susceptibility of the traveler, the specifics of the destination, the mode of transport, and on chance events. Ill-prepared travelers who underestimate travel risks may encounter a variety of health problems. In order to eventually increase the capability of...

Through reviewing and comparing the current virtual shopping malls web sites integrated VR into E-commerce, this paper analyzed both the advantages and disadvantages of two kinds of methods for product presentation: 2D image based and 3D model based presentation method. Using the virtual shopping mall (EasyMall) as a showcase, we presented the architecture of the system and the development tech...

In table 2 we present standard errors for our main estimates. For estimates that come from MRI, the GSS or the CNES, we compute standard errors through a nonparametric bootstrap over samples of respondents. For estimates that come from comScore aggregate data, that is not an option. Instead we perform a parametric bootstrap in which we model the share conservative of each website as an independ...

This paper deals with the phenomenon of online self-disclosure. Two qualitative data analyses of YouTube videos were conducted. The studies revealed emerging forms of self-disclosure online, which are not necessarily bound to conditions of visual anonymity. This finding puts previous research results into question, which stress the strong correlation between self-disclosure and visual anonymity...

This paper presents findings from a study examining the diffusion and adoption of online retailing in Saudi Arabia. Although the country has the largest and fastest growing Information and Communication Technologies (ICT) sector in the Arab region, growth in e-commerce activities has not progressed at a commensurate rate. In general, Saudi retailers have not kept pace with the global growth of ...
