The interaction of small molecules with non-covalent assemblies is of wide interest. The use of a magnetically active reporter nucleus allows information to be obtained in the presence of spectral overlap or in cases of high dynamic range. In this paper, we explore the interaction of a larger probe molecule, 6-fluoro-2-naphthoic acid with assemblies of sunset yellow using (19)F chemical shifts ...

Harris argues that if QALYs are used only 50% of the population will be eligible for survival, whereas if random methods of allocation are used 100% will be eligible. We argue that this involves an equivocation in the use of "eligible", and provides no support for the random method. There is no advantage in having a 100% chance of being "eligible" for survival behind a veil of ignorance if you ...

Software visualisation seeks to aid comprehension of software; however, there is still little progress in the evaluation of such visualisations. This paper reports on the current practice of evaluation in software visualisation. Four evaluation strategies are identified and discussed in order to identify strengths and weaknesses when applied to software visualisation. Areas for improvement are ...

This paper addresses the question whether a morphological boundary affects the position of a syllable boundary in young children's intuitive syllabifications of words. Bisyllabic words where a single intervocalic consonant is at the same time the final phoneme of the word stem are the ideal domain for studying the interaction of phonological and morphological knowledge. We presented the same se...

A B S T R AC T This study examined the moderating influence of two top management team (TMT) characteristics, namely managers possessing an MBA education or prior military experience, on the relationships between firm size and corporate criminal activity, and firm strategy and corporate criminal activity. The study utilized data from 184 Fortune 500 companies. The results suggest that both grad...

ELEPHANT CONTRACEPTION IS INCREASINGLY being identified as a solution to the problem of growing elephant numbers in conservation areas. As a result, it is now being incorporated into elephant management and policy in South Africa. We point out that elephant contraception may have numerous physical, social and ecological side-effects. These side-effects should be identified in advance and their ...

The ob gene was cloned in 1994 using the methodology of positional cloning. Leptin, the protein encoded by the ob gene, was identified in 1995 and shown to be a hormonal signal that regulates energy balance.14 Since its discovery 15 years ago, 30,943 articles on leptin have been written (S Korres, personal communication, 2009), providing an opportunity to assess, with some hindsight, the impact...

In the go/no-go lexical decision task (LDT), participants are instructed to respond as quickly as they can when a word is presented and not to respond if a nonword is presented. By minimizing part of the response selection process in the experimental task, the impact of response decision time on the obtained lexical decision time is probably reduced relative to the standard yes/no LDT (Gordon, ...

The article explores aspects of the role of prosody as a contextualization cue in aphasic conversation through auditory and acoustic analysis of an aphasic speaker's use of pitch variation in responses to closed yes/no-requests. The results reveal two prosodic realizations of 'yes' and 'no' contextualizing different kinds of responses: a flat realization with no prolongation and minimal pauses,...

Schott et al. (2007) have shown that the “tragedy of the commons” can be overcome when individuals share their output equally in groups of optimal size and there is no communication. The assignment to groups as either strangers or partners does not significantly affect this outcome. In this paper we investigate whether communication changes these results. Communication reduces shirking, increas...
