A validation of a new measure of activity in psychosis
No full textDespite demonstrated relationships between activity and clinical change, we lack effective measures of time use in psychosis. Existing time budget measures of activity are demanding to complete, and thus unsuited to routine clinical use as measures of change. Less burdensome 'check-box' measures are prone to bias and omission in the activities selected. We recently devised a simplified time budget measure of activity in psychosis which was piloted on a small sample [Jolly, S., Garely, P., Dunn, G., White, J., Aitken, M., Challocombe, F., Griggs, M., Wallace, M., Craig, T. 2005. A pilot validation study of a new measure of activity in psychosis. Soc. Psychiatry Psychiatr. Epidemiol. 40, 905-911]. This study is a larger scale validation. 276 participants with a recent relapse of non-affective psychosis completed the new time budget, together with an established measure of global social functioning, measures of positive and negative psychotic symptoms, positive symptom distress and affect. The time budget measure showed a correlation of 0.5 with both the SOFAS and the SANS avolition/apathy subscale. Activity levels were related to psychotic symptomatology, both positive and negative. Positive symptom distress was more strongly associated with activity levels than symptom severity and affective disturbance. We conclude that the time budget measure can be used as an indicator of social functioning, with potential as a measure of therapeutic change. We are currently investigating its sensitivity in this context. (c) 2006 Elsevier B.V. All rights reserved
Revealing the nanogeometry of WS2 nanoflowersby polarization-resolved Raman spectroscopy
No full textRecent studies of transition metal dichalcogenides (TMDs) have revealed exciting optical properties, such as stable excitons and chiral light–matter interactions. Chemical vapor deposition techniques provide a platform for the fabrication of nanostructures with diverse geometries, ranging from horizontal flakes to flower-like structures. Raman spectroscopy is commonly used to characterize TMDs and their properties. Here, we use polarization-resolved Raman spectroscopy to probe the nanogeometry and orientation of WS 2 nanoflower petals.Exciting the nanoflowers with linearly polarized light, we observe an enhanced Raman response from flower petals oriented along the excitation polarization direction. Furthermore, the helicity-resolved Raman response of vertically oriented wall-like flower petals exhibits clear differences with horizontally oriented flakes. Although the photoluminescence from the nanoflowers is strongly reduced, the Raman response upon excitation in resonance with the WS 2 excitonic transition does reveal the presence of the exciton, which results in a distinct temperature dependence of the Raman response.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.QN/Kuipers LabQN/Conesa-Boj LabQN/Quantum Nanoscienc
Emotion and psychosis: Links between depression, self-esteem, negative schematic beliefs and delusions and hallucinations
No full textBackground: The role of emotion in psychosis is being increasingly recognised. Cognitive conceptualisations of psychosis (e.g. [Garety, P.A., Kuipers, E.K., Fowler, D., Freeman, D., Bebbington, P.E., 2001. A cognitive model of the positive symptoms of psychosis. Psychological Medicine, 31, 189-195]) emphasise a central, normal, direct and non-defensive role for negative emotion in the development and maintenance of psychosis. This study tests specific predictions made by Garety et al. [Garety, P.A., Kuipers, E.K., Fowler, D., Freeman, D., Bebbington, P.E., 2001. A cognitive model of the positive symptoms of psychosis. Psychological Medicine, 31, 189-195] about the role of emotion and negative evaluative beliefs in psychosis.Methods: 100 participants who had suffered a recent relapse in psychosis were recruited at baseline for the Prevention of Relapse in Psychosis (PRP) trial. In a cross-sectional analysis, we examined the role of depression, self-esteem and negative evaluative beliefs in relation to specific positive symptoms (persecutory delusions, auditory hallucinations and grandiose delusions) and symptom dimensions (e.g. distress, negative content, pre-occupation and conviction).Results: Analysis indicated that individuals with more depression and lower self-esteem had auditory hallucinations of greater severity and more intensely negative content, and were more distressed by them. In addition, individuals with more depression, lower self-esteem and more negative evaluations about themselves and others had persecutory delusions of greater severity and were more pre-occupied and distressed by them. The severity of grandiose delusions was related inversely to depression scores and negative evaluations about self, and directly to higher self-esteem.Conclusions: This study provides evidence for the role of emotion in schizophrenia spectrum-disorders. Mood, self-esteem and negative evaluative beliefs should be considered when conceptualising psychosis and designing interventions. (c) 2006 Elsevier B.V. All rights reserved

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
