OBJECTIVES To systematically review the choice of comparator strategies in cost-effectiveness analyses (CEAs) of human papillomavirus testing in cervical screening. METHODS The PubMed, Web of Knowledge, and Scopus databases were searched to identify eligible model-based CEAs of cervical screening programs using human papillomavirus testing. The eligible CEAs were reviewed to investigate what ...

In this paper the architecture and implementation of Cooperative Information Agents (CIA) is described. Taking a language-action perspective to the design of CIAs allows for the specification of obligations and authorizations, and results in the separation of tasks (things the agentmust do) and contracts (mutually agreed commitments to the course of communication). The architecture describes th...

Good communication is the basis for effective cooperation. An area where cooperation is essential is multidisciplinary healthcare. In this paper we will present a research project that aims at promoting effective multidisciplinary communication in a healthcare environment. We will answer the question of whether empirical modelling of the communication and cooperation patterns can be done based ...

These two aspects combined (the content and the stance) represent a perspective.

Reinforcement omission has been used as a procedure for the evaluation of attentional and motivational processes. Studies show that the activation of some amygdala nuclei may be involved in the modulation of these processes. This study examined the reinforcement omission effects on behavioral repertoire of rats with lesions in the central nucleus and basolateral complex of the amygdala, using c...

This would make beomission expected in all child languages. What would this hypothesis lead us to expect about the infinitive form of be? In terms of semantic vacuity, non...
