POLITICS AND MEDIA RICHNESS IN WORLD WIDE WEB REPRESENTATIONS OF THE FORMER YUGOSLAVIA

ABSTRACT. Media-richness theory is applied to World Wide Web sites to demonstrate how Web-page designers are using hypertext markup language to shape conceptions of place and to provide competing visions of the events that have transpired in the former Yugoslavia. We argue that Web sites vary in their interactivity, strategically, to reduce equivocality surrounding conceptions of space and territory. Media-richness theory as applied here allows the development of a heuristic to understand how Web pages communicate information about geographical entities and help to shape perceptions of place.

X2检验假设分布有效性的岩体工程应用

在工程地质问题中许多现象是不确定、且具有随机分布的特性，而这种随机分布特性往往可以采用某种形式的密度函数来描述。采用Ｘ２检验假设分布有效性是一个重要的方法，采用该法可以获得观测数据最佳拟合的概率模型，通过自编程序可以同时检验多种概率密度函数并选取最佳模型。本文将介绍这一方法，并通过一个实例加以说明。

Transport in a 2-D saturated porous medium: A new method for particle tracking

A new method for solving the transport equation based on the management of a large numbe of particles in a discretized 2-D domain is presented. The method uses numerical variables to represent the number of particles in a given mesh and is more complex than the 1-D problem. The first part of the paper focuses on the specific management of particles in a 2-D problem. The method also would be valid for three dimensions as long as the medium can be modeled similar to a layered system. As the particles are no longer tracked individually, the algorithm is fast and does not depend on the number of particles present. The numerical tests show that the method is nearly numerical dispersion free and permits accurate calculations even for simulations of low-concentration transport. Because each mesh is considered as a closed system between two successive time steps, it is easy to add adsorption phenomenon without any problem of numerical stability. The model is tested under conditions that are extremely demanding for its operating mode and gives a good fit to analytical solutions. The conditions in which it can be used to best advantage are discussed.
