Postulational approaches attempt to understand the dynamics of belief revision by appealing to no more than the set of beliefs held by an agent and the logical relations between them. It is argued there that such an approach cannot work. A proper account of belief revision must also appeal to the arguments supporting beliefs, and recognize that those arguments can be defeasible. If we begin wit...

This theoretical article discusses the emerging concept of awareness of age-related change (AARC). We propose that a focus on AARC extends the research traditions on subjective age experiences and age identity and that examination of this concept can serve a stimulating role in social gerontology. After defining and contrasting AARC against similar concepts, several reasons for the relevance of...

interpretation: computing on properties readInt(x) if x>0 : x:= pred(x) x:= succ(x) writeInt(x) Q: Is output pos? A: abstractly interpret domain Int by Sign = {neg , zero, pos , any }: readSign(x) if isPos(x): x:= pred(x) x:= succ(x) writeSign(x) where succ(pos) = pos succ(zero) = pos succ(neg) = any succ(any) = any and pred(neg) = neg pred(zero) = neg pred(pos) = any pred(any) = any Calculate ...

The discovery or disclosure of an extramarital affair can have a devastating impact on partners, both individually and on the relationships. Research suggests that affairs occur relatively frequently in relationships and are a common presenting problem in couple therapy. However, despite their prevalence, there is little empirical treatment research in this area, and most therapists describe th...

Federalism is a political mechanism for promoting unityin-diversity in a heterogeneous society. The federal system through the IGR uses the IGM mechanism to provide understanding, cordiality balance and collaboration between and among units of government, and between government and the citizenry. In Nigeria’s federal relation, the IGR seems not to have facilitated the right harmonious interacti...

background and purpose: sleep disorders are a common problem in patients undergoing hemodialysis. poor sleep quality is considered as a potential predictor for mortality and reduced quality of life in these patients. this study aimed to evaluate subjective sleep quality in hemodialysis patients and its association with hemodialysis timing. methods: this descriptive-correlational study was condu...

How can flexible phasing be generated by a central pattern generator (CPG)? To address this question, we have extended an existing model of the leech heartbeat CPG's timing network to construct a model of the CPG core and explore how appropriate phasing is set up by parameter variation. Within the CPG, the phasing among premotor interneurons switches regularly between two well defined states - ...

Abstract Timing verification of multi-core systems is complicated by contention for shared hardware resources between co-running tasks on different cores. This paper introduces the Multi-core Resource Stress and Sensitivity (MRSS) task model that characterizes how much stress each places it sensitive to such resource stress. facilitates a separation concerns, thus retaining advantages tradition...

We investigated the nuclear higher order compartmentalization of chromatin according to its replication timing (Ferreira et al., 1997) and the relations of this compartmentalization to chromosome structure and the spatial organization of transcription. Our aim was to provide a comprehensive and integrated view on the relations between chromosome structure and functional nuclear architecture. Us...

It has been shown that articulator movements during speech are adjusted along a number of spatiotemporal dimensions. For example, variations in the extent of lip, jaw, or tongue motion are associated with proportional changes in the respective articulators' peak velocity. Modifications in the timing of lip and jaw actions are apparently constrained, exhibiting relative timing covariation. Sylla...
