In this paper we deene a sound and (theoretically) complete top-down derivation procedure for a well-founded semantics of logic programs extended with explicit negation (WFSX). By its nature, it is amenable to a simple interpreter implementation in Prolog, and readily allows pre-processing into Prolog, showing promise as an eecient basis for further development. The derivation method is directl...

Sexual selection theory affords a rationale for predicting that men, especially young men, may be more willing than women to risk harms and to discount the future in the pursuit of short-term gains. These propositions apply to many domains of risky behavior, and it is likely that they apply to decisions involving potential harms to the environment and health hazards as well. Two preliminary stu...

We propose a new realization of goal-directed query evaluation of (non-oundering) normal logic programs for the well-founded semantics. To this end we introduce a new magic templates transformation and give a new xed point characterization of the well-founded semantics, lifting an existing deenition from the ground to the non-ground case. The new xed point characterization enables us to show a ...

Rationale: Risk-standardized mortality rates (RSMRs) can provide important information about quality of care that is currently unavailable to hospitals. Variation in mortality, after adjusting for case-mix, may reflect differences in hospitals' general environments (such as coordination of care, patient safety policies, and staffing) or variation in care processes. Outcome measures can focus at...

This chapter suggests possibility-driven design as an alternative to the common problem-driven approach. A first part explores the concept of "possibilities" and how it relates to happiness and well-being. We further develop the notion of designing for the pleasurable life and the good life through a number of exemplary design cases. Each takes a possibility-driven approach, thereby highlightin...

The aim of this paper is to provide a survey on the recent development in level set methods in inverse problems and optimal design. We give introductions on the general features of such problems involving geometries and on the general framework of the level set method. In subsequent parts we discuss shape sensitivity analysis and its relation to level set methods, various approaches on construc...

This qualitative study aims to understand the factors motivating Korean migrants’ participation in weekly Charismatic Prayer Meetings in a Catholic Church. As music plays a crucial role in these meetings, the paper explores whether active engagement with music motivated the long-term commitment of participants to the meetings. The research is based on a thematic analysis of a focus group compri...

Personal Social Health and Economic (PSHE) education is a non-statutory school subject designed to facilitate the delivery of a number of key competencies relevant to health, safety and wellbeing. As well as contributing to learning objectives in regards to these topics PSHE education has been ascribed with weighty expectations for outcomes well beyond the classroom relating to physical, mental...
