Mothers of invention: an afterword

This paper offers a personal perspective on exchanges at the 2014 NIME panel entitled Gender, Education, Creativity in Digital Music and Sound Art, and also draws on discussion at the 2013 Oxford MusDig Gender Roundtable. Neither anachronistic institutional positions in a fast evolving cultural environment, nor opportunistic promotion of market-driven education programmes doomed to swift obsolescence, is likely to foster the diversity needed to sustain new creative energies in digital music and sound art. Class and race barriers are often indissociable from those that characterise gender discrimination, but this is not just a question of intersectionality. It also concerns thinking specifically about the gendered constructions of the objects and concepts we employ, and about the objectification of gender itself. This overview of a decidedly heterogeneous array of projects and initiatives endeavours to reflect our panel's emphasis on the imperative to uphold diversity and otherness

Temperature dependent characterization of optical fibres for distributed temperature sensing in hot geothermal wells

This study was performed in order to select a proper fibre for the application of a distributed temperature sensing system within a hot geothermal well in Iceland. Commercially available high temperature graded index fibres have been tested under in-situ temperature conditions. Experiments have been performed with four different polyimide coated fibres, a fibre with an aluminum coating and a fibre with a gold coating. To select a fibre, the relationship between attenuation, temperature, and time has been analyzed together with SEM micrographs. On the basis of these experiments, polyimide fibres have been chosen for utilisation. Further tests in ambient and inert atmosphere have been conducted with two polyimide coated fibres to set an operating temperature limit for these fibres. SEM micrographs, together with coating colour changes have been used to characterize the high temperature performance of the fibres. A novel cable design has been developed, a deployment strategy has been worked out and a suitable well for deployment has been selected.Comment: PACS: 42.81.Pa, 93.85.Fg, 47.80.Fg, 91.35.Dc, 07.20.Dt, 07.60.V

Illness representations, psychological distress and non-cardiac chest pain in patients attending an emergency department

Objective: Many patients who attend an emergency department (ED) with chest pain receive a diagnosis of non-cardiac chest pain (NCCP), and often suffer poor psychological outcomes and continued pain. This study assessed the role of illness representations in explaining psychological distress and continued chest pain in patients attending an ED. Methods: ED NCCP patients (N = 138) completed measures assessing illness representations, anxiety, depression and quality of life (QoL) at baseline, and chest pain at one month. Results: Illness representations explained significant amounts of the variance in anxiety (Adj. R² = .38), depression (Adj. R² = .18) and mental QoL (Adj. R² = .36). A belief in psychological causes had the strongest associations with outcomes. At one month, 28.7% of participants reported experiencing frequent pain, 13.2% infrequent pain and 58.1% no pain. Anxiety, depression and poor QoL, but not illness representations, were associated with continued chest pain. Conclusions: The findings suggest that (i) continued chest pain is related to psychological distress and poor QoL, (ii) interventions should be aimed at reducing psychological distress and improving QoL and (iii) given the associations between perceived psychological causes and psychological distress/QoL, NCCP patients in the ED might benefit from psychological therapies to manage their chest pain

The challenge of the middle mediastinal parathyroid

In most cases of persistent or recurrent hyperparathyroidism (HPT), the pathological parathyroid (PT) will be in the neck or accessible through the cervical approach, and in only a small percentage will median sternotomy be required. We present 3 cases of persistent HPT where the PT tissue was in the middle mediastinum. We acknowledge that this is a rare occurrence and that it cannot be explained adequately by standard embryological teaching. In cases requiring formal mediastinal exploration, the mediastinal exploration is not complete unless the middle mediastinum is carefully explored to exclude ectopic PT tissue . Dans la plupart des cas d'hyperparathyroïdie (HPT) persistante ou récidivante, la glande parathyroïdienne (PT) pathologique responsable se trouve souvent dans le cou ou est au moins accessible par une incision cervicale. Il est rare qu'une sternotomie médiane soit nécessaire. Nous présentons 3 cas d'HPT persistante dans lesquels la glande PT restante se trouvait dans le médiastin moyen. Nous reconnaissons qu'il s'agit d'une éventualité rare qui ne peut être expliquée par l'embryologie classique. Dans les cas où une exploration médiastinale réglée est nécessaire, il faut, pour être complet, ne pas oublier d'explorer le médiastin moyen pour exclure toute possibilité d'existence de tissu PT ectopique. En la mayoría de los casos de hiperparatiroidismo persistente o recurrente la glándula patológica se encuentra en el cuello o es accessible por un abordaje cervical, y sólo en un mínimo porcentaje se hace necesario realizar esternotomía. Presentamos 3 casos de hiperpartiroidismo persistente en los cuales el tejido paratiroideo anormal fue hallado en el mediastino medio, posterior al arco aórtico pero anterior a la carina y a los bronquios principales. Reconocemos que este es un hallazgo raro y que no puede ser adecuadamente explicado a la luz de los conocimientos embriológicos ordinarios. En casos que requieran exploracíon mediastinal formal, la exploración no puede ser considerada como completa a menos que el mediastino medio sea cuidadosamente inspeccionado a fín de excluir la presencia de tejido paratiroideo ectópico.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41284/1/268_2005_Article_BF01655485.pd
