No full textHelping organizations to marshal, analyze, discuss, and act on all of the available information about a situation playing out over space and time is a critical problem. GeoWorlds (http://www.isi.edu/geoworlds) is a component-based information management system that addresses this issue. It brings together information analysis, retrieval and collaboration tools and integrates digital library, geographic information systems (GIS), and remote sensor data management technologies. It provides three key services: 1) rapidly assembling a custom repository of geographic information about a region, 2) bi-directionally linking it to collections of document-based information from the World-Wide Web, and 3) monitoring real-time sensor data for information that might change conclusions or decisions formed on the basis of this rich information set. GeoWorlds framework enables synchronous and asynchronous collaboration over finding, filtering, organizing and visualizing the needed information
GeoWorlds: A Geographically Based Information System for Situation Understanding and Management
No full textDivision of labour and sharing of knowledge for synchronous collaborative information retrieval
No full textSynchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques
Economic development and the price level in Egypt, 1950-1962
No full textThis thesis on growth and the price level in Egypt,
is a case study of a country which is planning to enter
the take-off period at a time when a social and political
revolution is taking place. The period of study (1950-62)
covers a critical stage in the history of Egypt, since
it may be considered the transitional period in which the
country had to complete the structural changes necessary
for a dynamic economy. While in the earlier part of the
period of study, the economy was mainly based on the
principles of a free enterprise system, socialism emerged
in the later years, with the economy being subjected to
an overall plan. Thus, this study examines the functioning
of the various economic variables and their relationships
during such a stage of development and in view of such
social and political changes.
Growth and the price level have been examined from
both demand and supply viewpoints. In chapter III, a picture
of the working of the external forces is given while
chapter V is devoted to explaining the evolution of the,
public sector which has undergone many changes in conformity
with the changes in the overall political and economic
objectives of the country. Sectoral growth is examined in
Chapter IV while Chapter Vi is concerned with the system
of price controls. Finally, Chapter VII summarises the
main conclusions reached as regards development and changes
in the price level in Egypt during the period 1950-62.
An important contribution of this research is that
it collates and presents in a useful form a considerable
amount of statistical data on the Egyptian economy which
previously had not been easily available

Collaborative information space analysis tools
No full textThe DASHER Project at USC/ISI has focused upon helping organizations with rapid-response mission requirements. Such organizations need to be able to quickly stand up tiger teams backed by the information, materiel, and support services they need to do their job. To do so, they need to find and assess sources of those services who are potential participants in the tiger team. To support this very initial phase of team development, the project has developed information analysis tools that help make sense of sets of data sources in an intranet or internet: characterizing them, partitioning them, sorting and filtering them. These tools focus on three key issues in forming a collaborative team: helping individuals responsible for forming the team to understand what is available, helping them structure and categorize on the information available to them in a manner specifically suited to the task at hand, and helping them understand the mappings between their organization of the information and those used by others who might participate. DASHER’s Information Space Analysis Tools are unique in combining multiple methods to assist in this task. This makes the suite particularly well-suited to integrating additional technologies in order to create specialized systems
