    I denna uppsats jÀmförs i ett posthumanistiskt perspektiv tvÄ svenska romaner som diskuterar medvetandets natur och grÀnserna för det mÀnskliga. I En levande sjÀl frÄn 1980 av Per Christian (PC) Jersild (f. 1935) konfronteras vi med djur som utsÀtts för plÄgsamma djurförsök och med uppfödandet och programmerandet av aborterade mÀnskliga fosterhjÀrnor som skall utnyttjas som biodatorer i intelligenta maskiner. I SÄngen ur det kinesiska rummet frÄn 2014 av Sam Ghazi (f. 1967) stÄr i stÀllet möjligheten till en rent artificiell intelligens i fokus. De tvÄ böckernas frÄgestÀllningar kring vad som hÀnder i en framtid nÀr robotar blir alltmer mÀnniskolika och mÀnniskor alltmer robotlika Àr idag högaktuella. Inte minst gÀller det frÄgan om grÀnserna för det mÀnskliga och behovet av en etik som inkluderar andra vÀsen med ett medvetande. Sammanfattningsvis visar analysen i uppsatsen att en posthumanistisk lÀsning möjliggör nya och givande tolkningsmöjligheter av bÀgge verken trots att endast SÄngen ur det kinesiska rummet beskriver sin posthumana verklighet i ett posthumanistiskt perspektiv medan En levande sjÀl i huvudsak har en mÀnsklig utgÄngspunkt för sin gestaltning av Ypsilon. I ett posthumanistiskt perspektiv framtrÀder ocksÄ romanernas karaktÀr av moraliska tankeexperiment tydligt

    The UK Biobank offers cross-sectional epidemiological data collected on > 500 000 individuals in the UK between 40 and 70 years of age. Using the UK Biobank data, the aim of this study was to investigate the effects of functional hearing loss and hearing aid usage on visuospatial memory function. This selection of variables resulted in a sub-sample of 138 098 participants after discarding extreme values. A digit triplets functional hearing test was used to divide the participants into three groups: poor, insufficient and normal hearers. We found negative relationships between functional hearing loss and both visuospatial working memory (i.e., a card pair matching task) and visuospatial, episodic long-term memory (i.e., a prospective memory task), with the strongest association for episodic long-term memory. The use of hearing aids showed a small positive effect for working memory performance for the poor hearers, but did not have any influence on episodic long-term memory. Age also showed strong main effects for both memory tasks and interacted with gender and education for the long-term memory task. Broader theoretical implications based on a memory systems approach will be discussed and compared to theoretical alternatives

    High Temperature Superconducting (HTS, e.g. YBCO) microwave devices based on bulk or thin film ferroelectrics (e.g. Strontium Titanate-STO) are studied theoretically and experimentally. YBCO/STO/YBCO parallel-plate resonators and based on bulk single crystal STO are for electrically tunable high power filters, phase shifters and other devices in the frequency band 0.5-2.0 GHz of advanced microwave communication systems. Thin film YBCO/STO Inter-digital Capacitors (IDC), Coplanar Waveguides (CPW) phase shifters/delay lines are also designed and studied experimentally for low microwave power applications. Modelling problems of these devices and microwave losses in ferroelectrics are also discusse

    The Effect of functional hearing and hearing aid usage on verbal reasoning in a large community-dwelling population

    Objectives: Verbal reasoning performance is an indicator of the ability to think constructively in everyday life and relies on both crystallized and fluid intelligence. This study aimed to determine the effect of functional hearing on verbal reasoning when controlling for age, gender, and education. In addition, the study investigated whether hearing aid usage mitigated the effect and examined different routes from hearing to verbal reasoning. Design: Cross-sectional data on 40- to 70-year-old community-dwelling participants from the UK Biobank resource were accessed. Data consisted of behavioral and subjective measures of functional hearing, assessments of numerical and linguistic verbal reasoning, measures of executive function, and demographic and lifestyle information. Data on 119,093 participants who had completed hearing and verbal reasoning tests were submitted to multiple regression analyses, and data on 61,688 of these participants, who had completed additional cognitive tests and provided relevant lifestyle information, were submitted to structural equation modeling. Results: Poorer performance on the behavioral measure of functional hearing was significantly associated with poorer verbal reasoning in both the numerical and linguistic domains (p < 0.001). There was no association between the subjective measure of functional hearing and verbal reasoning. Functional hearing significantly interacted with education (p < 0.002), showing a trend for functional hearing to have a greater impact on verbal reasoning among those with a higher level of formal education. Among those with poor hearing, hearing aid usage had a significant positive, but not necessarily causal, effect on both numerical and linguistic verbal reasoning (p < 0.005). The estimated effect of hearing aid usage was less than the effect of poor functional hearing. Structural equation modeling analyses confirmed that controlling for education reduced the effect of functional hearing on verbal reasoning and showed that controlling for executive function eliminated the effect. However, when computer usage was controlled for, the eliminating effect of executive function was weakened. Conclusions: Poor functional hearing was associated with poor verbal reasoning in a 40- to 70-year-old community-dwelling population after controlling for age, gender, and education. The effect of functional hearing on verbal reasoning was significantly reduced among hearing aid users and completely overcome by good executive function skills, which may be enhanced by playing computer games.11 page(s

    The possibilities and the limitations of tunable narrow band recursive active MMIC filters with respect to future adaptive on-chip radar receiv- ers are investigated. We compare the measured and he simulated results of two recursive active MMIC ilters with the corresponding theoretical results obtained using our analytical filter models. A good agreement between these results is generally found. Using our analytical filter models we also estimate the noise and intermodulation properties of the low noise amplifier used in the filters that are necessary in order to achieve a filter performance adequate for future adaptive on-chip radar receivers
