IntroductionBrain tumours frequently cause language impairments and are also likely to co-occur with localised abnormal slow-wave brain activity. However, it is unclear whether this applies specifically to low-grade brain tumours. We investigate slow-wave activity in resting-state electroencephalography in low-grade glioma and meningioma patients, and its relation to pre- and postoperative language functioning.MethodPatients with a glioma infiltrating the language-dominant hemisphere and patients with a meningioma with mass effect on this hemisphere underwent extensive language testing before and 1 year after surgery. EEG (...) was registered preoperatively, postoperatively, and once in healthy individuals. Slow-wave activity in delta- and theta- frequency bands was evaluated visually and quantitatively by spectral power at three levels over the scalp: the whole brain, the affected hemisphere, and the affected region.ResultsGlioma patients had increased delta activity and increased theta activity before and after surgery. In these patients, increased preoperative theta activity was related to the presence of language impairment, especially to poor word retrieval and grammatical performance. Preoperative slow-wave activity was also related to postoperative language outcomes. Meningioma patients showed no significant increase in EEG slow-wave activity compared to healthy individuals, but they presented with word retrieval, grammatical, and writing problems preoperatively, as well as with writing impairments postoperatively.DiscussionAlthough the brain-tumour pathology in low-grade gliomas and meningiomas has a different effect on resting-state brain activity, patients with low-grade gliomas and meningiomas both suffer from language impairments. Increased theta activity in glioma patients can be considered as a language-impairment marker, with prognostic value for language outcome after surgery. (shrink)

_Reasonable Risk_ examines the concept of risk as it applies to everyday life in general and to alcohol consumption specifically. The book addresses how we assess risks, and the strategies we use to manage them. It examines the elements that shape our perceptions of risk-cultural influences, social factors, and how we are presented with information about risk. The final chapter of the book focuses on the role of risk in policy formulation, examining in particular how alcohol policies are developed within (...) the context of individual and societal responsibility.

Plagiarism is increasingly evident in business and academia. Though links between demographic, personality, and situational factors have been found, previous research has not used actual plagiarism behavior as a criterion variable. Previous research on academic dishonesty has consistently used self-report measures to establish prevalence of dishonest behavior. In this study we use actual plagiarism behavior to establish its prevalence, as well as relationships between integrity-related personal selection and workplace deviance measures. This research covers new ground in two respects: (a) That (...) the academic dishonesty literature is subject to revision using criterion variables to avoid self bias and social desirability issues and (b) we establish the relationship between actual academic dishonesty and potential workplace deviance/white-collar crime.

In his recent work, ‘Sport, Aesthetic Experience, and Art as the Ideal Embodied Metaphor’, Tim L. Elcombe explores links between sport and art from a pragmatically informed conception of aesthetic experience. However, Elcombe's work does not highlight the role of the imagination in the interpretation of the aesthetic something Michael Polanyi claims to be the ‘cornerstone of aesthetic theory’. With the backdrop of an increased interest in the aesthetics, phenomenology, and epistemology of sport, this discussion essay seeks to defend the (...) usefulness and value of definitional demarcation debates between sport and art, to use Polanyi’s distinctions among technical, scientific and artistic problems to support the claim that sport is not art, and to offer an account of how sport contributes in its own way to human flourishing and why it is no less valuable experientially than art.
