    This thesis examines the extent to which third world organisations have participated in the shaping, control and benefits of development theory and practice. It concludes that development theory has been a creation of the first world acting upon the third world which is often perceived as powerless to help itself. Modernisation theory, development theory, alternative theories and neo-liberalism are all theories that developed out of the first world experience of development. Development theory has not been shaped by the third world rather it has been manipulated and controlled from within the first world. The very poor of the poorest countries have not benefited from development theory. Participation, also perceived as empowerment, has been lauded by development practitioners as the new panacea for development ills. Even though such participation is not so evident in reality, third world organisations are becoming more participatory, especially where first world organisations have changed their role from funder and provider to solidarity partners and advocators (within their own country). This thesis examined the potential of the Internet to increase the participation of third world organisations in voicing their justice and development issues to the first world. The Internet is only a participatory tool when used in a participatory environment. Its use will not necessarily ensure greater participation, of the third world, in development issues. As yet the Internet's potential is largely unrealised. This thesis conducted descriptive research into the extent that third world organisations use the Internet to further their justice and development objectives. The research found that third world use of the Internet was low compared to first world use of the Internet. This thesis recommends that the use of email subscription lists and World Wide Web sites by grassroots organisations from within third world countries is a unique opportunity to promote the third world perception of development issues to the first world

    Evaluation of an Internet Document Delivery Service

    An Internet-based Document Delivery Service (DDS) has been developed within the framework of the CNR ( the Italian Research National Council) Project BiblioMIME, in order to take advantage of new Internet technologies and promote cooperation among CNR and Italian university libraries. Adopting such technologies changes the traditional organisation of DDS and may drastically reduce costs and delivery times. An information system managing DDS requests and monitoring the temporal evolution of the service has been implemented, running on the local-area network of a test-site library. It aims to track number and types of documents requested and received, user distribution, delivery times and types (surface mail, fax, Internet), to automate repetitive manual procedures and to deal with the various accounting methods used by other libraries. Transmission of documents is carried out by means of an e-mail/Web gateway system supporting document exchange via Internet, which assists receiving libraries in retrieving requested documents. This paper describes the architecture and main design features of the e-mail/Web gateway server (the BiblioMime server). This approach permits librarians to continue using e-mail service to send large documents, while resolving problems that users may encounter when downloading large size files with e-mail agents. The library operator sends the document as an attachment to the destination address; on fly the e-mail server extracts and saves the attachments in a web-server disk file and substitutes them with a new message part that includes an URL pointing to the saved document. The receiver can download these large objects by means of a user-friendly browser. We further discuss the data gathered during the triennium 1998-2000; this consists of about 5,000 DDS transactions per annum with 300 other Italian scientific and bio-medical libraries and commercial document suppliers. Use of the instruments described above allowed us to evaluate the performance of service “before” and “after” the use of Internet Document Delivery and to extract some critical data regarding DDS. Those include: a) libraries with which we have greater numbers of exchanges and their turnaround times; b) extraordinary reduction in costs and delivery times; c) the most frequently requested serial titles (allowing cost-effective decisions on new subscriptions); d) impact on DDS of library participation in consortia which allow user access to greater numbers of online serials

    STAMP: SMTP server topological analysis by message headers parsing

    Get PDF
    This paper presents STAMP: a tool to analyse SMTP servers overlay topology. STAMP builds a weighted and oriented graph from an email database, an email log or just a simple email header allowing a post-analysis of the SMTP overlay structure and the identification of the paths used by an email. The objective of this tool is twofold. STAMP allows to automatically perform an analysis of the SMTP topology for debugging (e.g, message delay, emails loop, ...) and for metrology purposes. While several traceroute-like measurements projects try to map the Internet, to the best of our knowledge, no tool allows to drive an analysis of the SMTP overlay network. Thus, the goal of the resulting graph is to develop methods (from graph theory, statistical analysis, ...) to identify relaying problems. We aim to explore the impact of IP network problems over emails delivery (and respectively: emails’ traffic over IP networks) in conjunction with IP measurements driven synchronously. In the present paper, we introduce the design and the measurement methodology of the STAMP software and as second contribution, bring out to the networking community the tool and some measurements databases

    S-100 Overlays: A Brave New World?

    Get PDF
    Marine Information Overlay (MIO) is a generic term used to describe chart and navigation related information that supplement the content that is already contained in an ENC. This includes both static and dynamic information such as tide/water level, current flow, meteorological, oceanographic, and environmental protection. With the advent of S-100 and S-101, there is increased interest in providing a wide variety of ‘new’ overlay information. This paper provides a brief history of S-57 MIOs. Examples of navigational and non-navigation MIOs are given in terms of how currently used, by who, and for what purpose. Recommendations are provided for making a transition from S-57 MIOs to S-100 overlays that can be used with the ‘Next Generation’ ENC. More specifically, what has been proposed, how should they work, who will provide, and some future challenges/opportunities related to implementation

    Tato prĂĄce se zabĂœvĂĄ analĂœzou současnĂœch open source ƙeĆĄenĂ­ pro zabezpečenĂ­ DNS zĂłn pomocĂ­ technologie DNSSEC.

CĂ­lem knihovny je zachovat vĂœhody stĂĄvajĂ­cĂ­ch ƙeĆĄenĂ­ a vyƙeĆĄit jejich nedostatky. SoučástĂ­ nĂĄvrhu je i sada nĂĄstrojĆŻ pro sprĂĄvu politiky a klíčƯ. Funkčnost vytvoƙenĂ© knihovny je ukĂĄzĂĄna na jejĂ­m pouĆŸitĂ­ v serveru Knot DNS.This thesis deals with currently available open-source solutions for securing DNS zones using the DNSSEC mechanism. Based on the findings, a new DNSSEC library for an authoritative name server is designed and implemented. The aim of the library is to keep the benefits of existing solutions and to eliminate their drawbacks. Also a set of utilities to manage keys and signing policy is proposed. The functionality of the library is demonstrated by it's use in the Knot DNS server.
