AIDS-related mycoses: the way forward.

The contribution of fungal infections to the morbidity and mortality of HIV-infected individuals is largely unrecognized. A recent meeting highlighted several priorities that need to be urgently addressed, including improved epidemiological surveillance, increased availability of existing diagnostics and drugs, more training in the field of medical mycology, and better funding for research and provision of treatment, particularly in developing countries

Intercultural consolidation: exploring the experiences of internationally qualified social workers and the English post-qualifying framework

The increasing movement of social workers from one country to another, especially with the expansion of the European Union, appears likely to pose a number of challenges to host countries in terms of receiving, supporting and developing social workers who trained in other countries. This paper explores the provision of a post-qualifying ‘consolidation’ module to a group of 15 internationally qualified social workers and evaluates both the student experience and the cultural challenges faced by individual social workers who came to practise in England after qualifying in their home countries. These social workers undertook the module at the University of Greenwich in London, England, and were selected for this as a part of a project with two London boroughs. Factors which have an important influence on successful ‘settlement’ into a new role and culture are discussed and analysed. It is argued that the provision of post-qualifying training can be a key part of the acculturation process but timing and other factors need to be considered. The paper explores what was learned from the project and its evaluation about the experiences and support needs of internationally qualified social workers. The project took place in 2007-2008 and was evaluated

Parameter Baserad Prediktionsmodell för Upplevd Talkvalité i Säker VoIP trafik

More and more sensitive information is communicated digitally and with thatcomes the demand for security and privacy on the services being used. An accurateQoS metric for these services are of interest both for the customer and theservice provider. This thesis has investigated the impact of different parameterson the perceived voice quality for encrypted VoIP using a PESQ score as referencevalue. Based on this investigation a parametric prediction model has been developedwhich outputs a R-value, comparable to that of the widely used E-modelfrom ITU. This thesis can further be seen as a template for how to construct modelsof other equipments or codecs than those evaluated here since they effect theresult but are hard to parametrise. The results of the investigation are consistent with previous studies regarding theimpact of packet loss, the impact of jitter is shown to be significant over 40 ms.The results from three different packetizers are presented which illustrates theneed to take such aspects into consideration when constructing a model to predictvoice quality. The model derived from the investigation performs well withno mean error and a standard deviation of the error of a mere 1:45 R-value unitswhen validated in conditions to be expected in GSM networks. When validatedagainst an emulated 3G network the standard deviation is even lower.
