Water vendors, selling water door-to-door from donkey carts, are an important source of domestic supply in low-income urban areas in Sudan, as in other developing countries. A study of the demand for this service showed that it was of negligible elasticity, with no evidence of direct control of the price by a monopoly or cartel. It follows that the price of water paid by the poor could be great...

This paper presents findings of a global exploratory study on the landscape public access venues in 25 countries around the world. The goal of the project was to better understand the users of public access venues and their needs, this being one of several pape...

This work is part of a research project whose main objective is to understand the impact that the use of Information and Communication Technology (ICT) has on the teaching and learning process on the subject of Physics. We will show that, with the use of a storm simulator, physics students improve their learning process on one hand they understand storm phenomenon, and on the other hand they as...

The problem is not with the information itself, but rather with its volume and the unwieldy ways currently provided for interacting with digital content. My research focus is to create interactive informa...

The areal extent and spatial distribution of evergreen forests in the tropical zones are important for the study of climate, carbon cycle and biodiversity. However, frequent cloud cover in the tropical regions makes mapping evergreen forests a challenging task. In this study we developed a simple and novel mapping algorithm that is based on the temporal profile analysis of Land Surface Water In...

Purpose – To provide a social-theoretic framework which explains how e-commerce affects social conditions, such as availability of information and equality of access to information, influences actors’ behavior, shapes e-commerce business models, and in turn impacts industry structure. Design/methodology/approach – Empirical investigation based on one-hour interviews with owners/managers of nine...

As well as conveying a message in words and sounds, the speech signal carries information about the speaker's own anatomy, physiology, linguistic experience and mental state. These speaker characteristics are found in speech at all levels of description: from the spectral information in the sounds to the choice of words and utterances themselves. This chapter presents an introduction to speech ...

Equitable access to information is one of the most vital principles in the emerging global information economy, and there is perhaps no region of the world that epitomizes the conflict between the information haves and have-nots than Sub-Saharan Africa (SSA). In addition to the more traditional forms of poverty, a new concept, binformation poverty,Q has emerged that better explains the true nat...

It is a well-known fact that despite the rapid growth of technology over the past years, not all people have equal access to information and knowledge. Senior citizens are one major example of people being excluded from the abundance of services that technology has to offer nowadays, which results in feelings of inactiveness, loneliness and isolation. This paper presents a European Project in t...
