Have music lost its rhythm? : A study about different factors impact on musical education

Syftet med undersökningen är att utifrån ett ramfaktorperspektiv undersöka vilka faktorer som musiklärare i år 7–9 upplever påverkar deras undervisning. De frågeställningar som studien utgår ifrån är: • Vilka faktorer upplever musiklärare påverkar musikundervisningen? • Hur upplever lärare att dessa faktorer påverkar deras möjligheter att genomföra sin undervisning? Studien bygger på intervjuer med sju lärare som undervisar i ämnet musik. I resultatet syns musiklärarnas upplevelser kring olika faktorer som påverkar musikundervisningen där gruppstorlek, budget och lokalmöjligheter är viktiga faktorer. Musiklärarna lyfter även problematiken kring bristen på kompetensutveckling samt hur lärarkompetens kan vara en betydande ramfaktor för att hjälpa eleverna i deras inlärning och utveckling i ämnet. I studien benämns även förväntningarna ifrån ledning, kollegor och elever som en faktor då kravet på en musiklärares kompetens samt ansvar upplevs stort. Detta anser musiklärarna sätter press på hur elevernas kunskaper i musik ska vara och att man som ensam musiklärare på en skola ska axla många roller

Diabetic retinopathy as a predictor for peripheral compression neuropathies, a registry-based study

Diabetes is characterized by hyperglycaemia and entails many complications, including retinopathy and entrapment neuropathies, such as ulnar nerve entrapment (UNE) and carpal tunnel syndrome (CTS). Hyperglycaemia damages the nerves of the retina, as well as peripheral nerves. There is a correlation between entrapment neuropathies and retinopathy in patients with diabetes, but whether patients with diabetic retinopathy are more prone to develop CTS and UNE is uncertain. Hence, the aim was to investigate if retinopathy can be used as a factor predicting the development of CTS and UNE. Data from 95,437 individuals from the National Diabetes Registry were merged with data from the Skåne Healthcare Registry. The population was analysed regarding prevalence of CTS or UNE and retinopathy status. Population characteristics were analysed using the Chi2-test, Student’s Independent T-test, and the Mann-Whitney U-test. Two logistic regression models were used to analyse the odds ratio (OR) for development of CTS and UNE depending on retinopathy status, adjusted for possible confounders. Both CTS and UNE were more frequent among those with retinopathy, compared to those without (CTS: 697/10,678 (6.5%) vs. 2756/83,151 (3.3%; p<0.001), (UNE: 131/10,678 (1.2%) vs. 579/83,151 (0.7%; p<0.001)). The OR for developing CTS for individuals with type 1 diabetes and retinopathy was 2.40 (95% CI 2.06–2.81; p<0.001) and of developing UNE was 1.53 (0.96–2.43; p = 0.08). The OR for developing CTS for individuals with type 2 diabetes and retinopathy was 0.93 (0.81–1.08; p = 0.34) and for UNE 1.02 (0.74–1.40; p = 0.90). Diabetic retinopathy is associated with a higher risk of developing CTS and UNE, but the association seems to be mediated by the duration of the diabetes. Higher HbA1c levels, longer diabetes duration and higher BMI are significant risk factors for developing CTS and UNE in type 1 and type 2 diabetes

Surgically Treated Carpal Tunnel Syndrome and Ulnar Nerve Entrapment at the Elbow in Different Occupations and their Effect on Surgical Outcome

OBJECTIVE: We investigated whether certain occupations were over-represented among surgically treated carpal tunnel syndrome and ulnar entrapment at the elbow, and if manual occupation affected surgical outcome.METHODS: We included 9030 patients operated for CTS and 1269 for UNE registered in the Swedish National Quality Register for Hand Surgery (HAKIR) 2010-2016. Occupational data was retrieved from Statistics Sweden. Outcome was assessed using the QuickDASH questionnaire.RESULTS: In patients operated for CTS, there were more assistant nurses, attendants/care providers/personal assistants, nannies/student assistants, carpenters/bricklayers/construction workers, cleaners, nurses, and vehicle mechanics than in the general population. In the UNE population, assistant nurses and attendants/care providers/personal assistants were over-represented. Manual workers with CTS scored the preoperative QuickDASH higher than non-manual workers.CONCLUSIONS: Manual workers are overrepresented among surgically treated CTS and UNE. Manual workers with CTS have more symptoms preoperatively than non-manual workers

Effects of Nonlinear Transmit Amplifiers in Smart Antennas for Wireless Systems

The use of array antennas in mobile telecommunication systems has proven to increase the spectral efficiency of the system. However, the use of an N element array antenna at the basestation site implies that the amount of radio hardware must be increased N -fold. This will make basestations larger, more expensive and more power consuming. Much effort must be put into combine functionality as amplification, using a multicarrier amplifier (MCPA), capable to amplify a number of signals with different carrier frequencies in a single device. In this study we investigate by measurements and simulations the effects of a nonlinear MCPA in the downlink for a cellular system. The nonlinearity will introduce intermodulation distortion and also decrease the null-depth of the beamformer. This will have an impact on the carrier-to-interference ratio of the mobiles in the system. The simulations gives the CDF of the received carrier-to-interference ratio of the mobiles, which can be used in link bud..

Analysis of Quantisation Effects in Adaptive Array Antennas

Adaptive antennas are used to increase the spectral efficiency in mobile telecommunication systems. The precision required in the beamforming and in the calibration process is evaluated by simulations and verified by measurements on an adaptive antenna testbed. As a performance measure, the carrier to interference ratio (CIR) on adaptive antenna output is used. A theoretical expression for the output CIR is derived and compared with simulations and measurements. The testbed is designed for the DCS-1800 system and operates in the uplink only. It uses the hybrid-digital-analog beamformer, where the weights are computed in a DSP, but the beamforming is performed on RF or IF frequency using analog phase-shifters and attenuators. We show how the simulation tool can be used to make the design balanced and thus avoiding over- or under-dimensioning of hardware parameters such as weight accuracy and calibration accuracy. This is important for the system-designer, and can be used to find perfor..
