With the prevalent use of smartphones and the emergence of the fourth generation of mobile telecommunications technology (4G), an increasing number of employees use their smartphones with cellular data for non-work related purposes during working hours. Compared to traditional cyberloafing, smartphone with cellular data provides a more convenient and private access to the Internet without any r...

Statistical mechanics is an asymptotic theory valid in the limit of an infinite number of degrees of freedom. The study of small-dimensional chaos, starting from the papers by Lorenz [1]and Henon and Heiles [2], raises the question: What is essential for the laws of statistical mechanics to be true —a large number of degrees of freedom or chaos? For ergodic Hamiltonian systems the answer was gi...

Introduction Geriatric patients and their relative fragility with respect to younger patients represent a surgical dilemma for the general surgeon. This has led surgeons to adopt "tailored" techniques and strategies to treat them. The rapid increase of this aged population has given the clinician the chance to push forward the knowledge on this subset of patients and challenge previous concepts...

The growing popularity of open systems in organizational computing has made it important to understand the key determinants of open-systems adoption. Existing innovation diffusion theories, however, have been criticized for their inability to provide an adequate explanation for diffusion of complex organizational technology. This study used the `technology-push' (TP) and `need-pull' (NP) concep...

We present a novel visual attention tracking technique based on Shared Attention modeling. Our proposed method models the viewer as a participant in the activity occurring in the scene. We go beyond image salience and instead of only computing the power of an image region to pull attention to it, we also consider the strength with which other regions of the image push attention to the region in...

By considering the master equation of asymmetric exclusion process on a one-dimensional lattice, we obtain the most general boundary condition of the multi-species exclusion processes in which the number of particles is constant in time. This boundary condition introduces the various interactions to the particles, including ones which have been studied yet and the new ones. In these new models,...

This article analyses the push and pull factors that bring visitors to the Iranian national parks. The study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. Survey conducted in Boujagh National Park, an area of 3177 hectares located in the north of the Iran, produced 400 questionnaires. The factor analysis identified four push ...
