Joking, storytelling, artsharing, expressing affection: a field trial of how children and their social network communicate with digital images in leisure time

Abstract: Increasing use of mobile phones in leisure and communication with digital images are important and current issues in the field of telecommunications. However, little is known about how images would be used in leisure related communication. According to our experience field trials are the best way of studying it. In this paper, we describe a field-trial case study of leisure related communication with digital images. Moreover, we discuss the advantages of conducting field trials as part of product concept design process.

Sequence dependence of DNA translocation through a nanopore

Abstract: We investigate the dynamics of DNA translocation through a nanopore using 2D Langevin dynamics simulations, focusing on the dependence of the translocation dynamics on the details of DNA sequences. The DNA molecules studied in this work are built from two types of bases A and C, which has been shown previously to have different interactions with the pore. We study DNA with repeating blocks AnCn for various values of n, and find that the translocation time depends strongly on the block length 2n as well as on the orientation of which base entering the pore first. Thus, we demonstrate that the measurement of translocation dynamics of DNA through nanopore can yield detailed information about its structure. We have also found that the periodicity of the block sequences are contained in the periodicity of the residence time of the individual nucleotides inside the pore.

Competitive dynamics, strategic consistency, and organizational survival

Abstract: This study investigates strategic consistency in competitive behavior. We construct a logically consistent evolutionary model, providing a causal argument to link a level of strategic consistency to long-term organizational survival. According to our results, strategic consistency seems to be related to both organizational survival and the most efficient change over time concerning the key elements of a firm's strategy. One of the benefits of the model is that some of the components and processes may be manipulated through experimental or simulation interventions. This means that the model can be formally tested in future studies and managers can use it to fine-tune patterns of competitive behavior. Copyright © 2008 John Wiley & Sons, Ltd.
