Some substance dependent individuals (SDI) suffer from a decision-making impairment akin to that seen in neurological patients with lesions of the ventromedial (VM) prefrontal cortex. The somatic-marker hypothesis posits that decision-making is a process that depends on emotion and that deficits in emotional signaling will lead to poor decision-making. In this study, we tested the hypothesis th...

The aim of this study was to determine the degree of Anguillicoloides crassus infection in European eel inhabiting Polish waters based on selected parasitic descriptors and on anatomical pathology of the swimbladder using macroscopic methods. In all, 154 European eel specimens were sampled from eleven sites in Poland and A. crassus was present in the swimbladder of 114 fish. The intensity of A....

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...
