We consider the problem of reliable epidemic dissemination of a rumor in a fully connected network of n processes using push and pull operations. We revisit the random phone call model and show that it is possible to disseminate a rumor to all processes with high probability using Θ(lnn) rounds of communication and only n+o(n)messages of size b, all of which are asymptotically optimal and achie...

This paper presents a distributed algorithm to disseminate events in a publish/subscribe system, where processes publish events of certain topics, organized in a hierarchy, and expect events of topics they subscribed to. Every topic defines a dynamic notion of “community”, gathering the processes which publish on that topic or subscribe to it. Our algorithm is completely decentralized (no broke...

BACKGROUND Evidence-based clinical practice guidelines (CPGs) are statements that provide recommendations to optimize patient care for a specific clinical problem or question. Merely reading a guideline rarely leads to implementation of recommendations. The American Academy of Neurology (AAN) has a formal process of guideline development and dissemination. The last few years have seen a burgeon...

In the SEMPROM project “Products Keep a Diary” smart labels give products a memory and support intelligent logistics. Within the ICT 2020 research program of the German Federal Ministry of Education and Research the Innovation Alliance “Digital Product Memory” (IA DPM) is developing key technologies for the Internet of Things in the cooperative project SEMPROM. Through the use of integrated sen...

This paper reports on a Delphi study undertaken by a health librarian and two midwifery professionals, to determine the research priorities of midwives working in NHS Highland. Six important topics were identified: workforce issues, second stage of labour, obesity in pregnancy, women’s expectations of pregnancy and of childbirth, place of birth, and breastfeeding. Related evidence was examined ...

We present low-overhead protocols for disseminating streaming data in an interimistic environment in which the availability of computers, networks, and other resources is very unpredictable. An important example of such an environment is the state of computing and communication resources immediately following a natural disaster or a similar disruptive event. A key characteristic of such environ...

The paper argues that competitive intelligence is a vital function and attempts to study how it is distributed, especially by technologies, within organizations. Related topics, the sources of competitive intelligence, and who distributes and receives competitive intelligence, are also addressed. A literature-based study is extended by a quantitative survey of members of the Society of Competit...

Knowledge and understanding of the law by the citizens of a state is crucial for the legitimacy of governance. There are many examples of legal knowledge deficits, e.g., the lack of legal knowledge of the European Union in its citizens. In order to provide them with understandable and reliable information about the legal framework underlying the European Union, it is necessary to determine how ...

This paper describes Transparent Replication through Invalidation and Prefetching (TRIP), a self tuning data replication middleware system that enables transparent replication of large-scale information dissemination services. The TRIP middleware is a key building block for constructing information dissemination services, a class of services where updates occur at an origin server and reads occ...
