This work presents a new application of a mathematical theory of psychological behavior from Usher and McClelland and the random utility model from McFadden, to the web user behavior. The model describes the stochastic behavior of a general kind of web users, consisting of the probability of following a hyperlink for a specific length of time. The simulation experiment together with the artific...

Understanding and forecasting the health of an online community is of great value to its owners and managers who have vested interests in its longevity and success. Nevertheless, the association between community evolution and the behavioural patterns and trends of its members is not clearly understood, which hinders our ability of making accurate predictions of whether a community is flourishi...

The abundance of short-range radios, such as Bluetooth, in the current office and urban environments opens up new possibilities for data modeling and analysis. Although individual devices are constantly moving and active only sporadically, various environments have specific statistical characteristics. Mobile handsets are often personal in nature, so the statistics reflect also behavioral patte...

What are the cognitive processes in play when someone uses a visualization tool to interactively explore a new dataset? Here, we focus on one particular type of visualization—the scatter plot—which, despite (or perhaps because of) its simplicity, is still one of the most frequently used plot types in many dataintensive disciplines. We conducted a pilot study to investigate how expert astronomer...

A better understanding of the human user’s expectations and sensitivities to the real-time behavior generated by virtual agents can provide insightful empirical data and infer useful principles to guide the design of intelligent virtual agents. In light of this, we propose and implement a research framework to systematically study and evaluate different important aspects of multimodal real-time...

Part of the motivation behind the evolution of learning environments is the idea of providing students with individualized instructional strategies that allow them to learn as much as possible. It has been suggested that the goals an individual holds create a framework or orientation from which they react and respond to events. There is a large evidence-based literature which supports the notio...

The dimensions of telecare services are analyzed and contrasted to theories of behavioural intentions. Factors influencing the adoption of innovations are derived from target group specific factors and telecare features. We present results from an empirical study which interlinks users’ characteristics, technology and the intention to adopt technology based services. We examine customers above ...

The mating call of Isoperla bipartita is described. The male call is composed of 3–10 groups, each of 1–4 rubs. The times between rubs average 89.52msec (between first and second), 43.52msec (between second and third) and 35.28 msec (between third and fourth). The time between two groups averages 180.75 msec and varies from 142 to 290msec. The female answer is composed of a beat and rub repeate...

We study the situation of a decision-maker who aims to encourage the players of an evolutionary game theoretic system to follow certain desired behaviours. To do so, she can interfere in the system to reward her preferred behavioural patterns. However, this action requires certain cost (e.g., resource consumption). Given this, her main goal is to maintain an efficient trade-off between achievin...

Decision making (DM) is a knowledge intensive process that demands good management of knowledge to generate a desired process outcome. The KM behavioral patterns that transpire while managing knowledge during DM affect the process outcomes. Therefore, in order to understand KM behaviors to generate a desired process outcome, it is crucial to systematically study the nature of KM behaviors that ...
