in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

Narrativists about well-being claim that our lives go better for us if they make good stories—if exhibit cohesion, thematic consistency, and narrative arc. Yet narrativism leads to mistaken assessments of well-being: prioritizing makes it harder balance change pursuits, pushes toward one-dimensionality, can’t sense the diversity lives. Some ways softening key narrativist claims mean view tell v...

In this paper we report on a series of experiments designed to investigate the combination of term and document weighting functions in Information Retrieval. We describe a series of weighting functions, each of which is based on how information is used within documents and collections, and use these weighting functions in two types of experiments: one based on combination of evidence for ad-hoc...
