To help users cope with information overload, Selective Dissemination of Information (SDI) will increasingly become an important tool in wide area information systems. In an SDI service, users post their long term queries, called pro les, at some SDI servers and continuously receive new, ltered documents. To scale up with the volume of information and the size of user population, we need a dist...

I examine key SDI concepts: ‘information’, ‘decision processes’, ‘people’, ‘management systems’, ‘social structure’ and ‘information technology’. I attempt to make explicit commonly held assumptions about the nature of these concepts, the ways they contribute to a ‘construction’ view of SDI implementation and their apparent disconnectedness with the realities in the developing world. I suggest ...

Background. The utility of serologic testing to evaluate vaccine efficacy of seasonal inactivated influenza vaccine (IIV) is controversial. We aimed to evaluate the efficacy of IIV against serologically diagnosed influenza infection (SDI) and reverse-transcription polymerase chain reaction-confirmed influenza illness (PCR-CI) in women vaccinated during pregnancy. Methods. We undertook a post ...

Intrinsic signal optical imaging (ISOI) can be used to map cortical function and organization. Because its detected signal lasts 10+s consisting of three phases, trials are typically collected using a long (tens of seconds) stimulus delivery interval (SDI) at the expense of efficiency, even when interested in mapping only the first signal phase (e.g., ISOI initial dip). It is unclear how the ac...

Substance-dependence is highly associated with executive cognitive function (ECF) impairments. However, considering that it is difficult to assess ECF clinically, the aim of the present study was to examine the feasibility of a brief neuropsychological tool (the Frontal Assessment Battery - FAB) to detect specific ECF impairments in a sample of substance-dependent individuals (SDI). Sixty-two s...

Information and communication technology (ICT), information infrastructure (II), geographic information system (GIS), and spatial data infrastructure (SDI) have interdependences. However, there has not been systematic exploration of their dependences, and therefore the nature of their relationships is not precisely known. Here, we use the “Bermuda” metaphor to initiate the discussion on which o...

This supplemental material gives the extended definitions of the tuple operations, lists the definition of some transformation operators, details the examples about DEVIATION, SEQBIN, and LONGESTPLATEAU, and describes the experimental protocol for the experiments. 1 Extended Definitions of Tuple Operations The projection 〈vi1 , . . . , vik〉 of a tuple 〈v1, . . . , vn〉 onto a subset of its compo...

Local government has been recognised as an early leader in the development, deployment and innovation in spatial information systems. The introduction of corporate wide spatial data portals within local government was as significant as the release of Google Earth to the wider public. Although these information systems continue to expand and mature, the potential for these local spatial data inf...

In this study, we proposed a stochastic deletion-insertion (SDI) algorithm for constructing large-scale linkage maps. This SDI algorithm was compared with three published approximation approaches, the seriation (SER), neighbor mapping (NM), and unidirectional growth (UG) approaches, on the basis of simulated F(2) data with different population sizes, missing genotype rates, and numbers of marke...
