Popular Abstract in Swedish Karaktäristiskt för människors påståenden om tidigare händelser och mer stabila fakta i deras omvärld är att de är förknippade med en viss grad av subjektiv säkerhet eller konfidens med avseende på om påståendena överensstämmer med vad som var eller är fallet. Ett exempel är ögonvittnens konfidens i påståenden om att ha pekat ut rätt gärningsman. Den grad av konfidens eTheoretical accounts and models of calibration typically explain the degree of realism (validity) in confidence and frequency judgments in terms of different cognitive and methodological factors. The present thesis demonstrates that also social factors are of importance for the degree of realism in these types of metacognitive judgments. The results of Study I showed improved realism in pairs’ con

A wavelet generator producing 100 ps short pulses at 60 GHz is presented. The wavelet generator consists of a gated tunnel diode (GTD) integrated in parallel with an inductor. This forms a negative differential conductance (NDC) oscillator with the ability to switch the NDC property on and off, which makes it possible to generate short pulses. In the experiments described, the wavelet generator dr

Political participation research has consistently shown that age and education among other factors, to a large extent determine who the activists are. The rise of social media services such as Facebook has however prompted hopes that new and more flexible forms of participation might lead to reduced inequality in political participation. This paper uses unique data on the political uses of social

This paper examines references of visual product identity in product design. The perception of identity is the result of a composite experience of the presentational and representational dimensions of the product. As consumers to a large degree create their value perceptions of products and brands based on the design of the product, it is important for companies to understand how perceptions of id

The reassignment technique is used to increase the localization for signals that have closely located time-frequency components. For Gaussian components the reassignment based on an optimal (matched) window spectrogram will result in a single point where all mass is located. For non-optimal windows, the reassignment procedure can be optimally rescaled to fulfill the single point mass location. Non

The proper handling of alarms is crucial to automated process control. In practice, many alarms are only distractive and do not represent a fault situation. Here, a toolbox is proposed that aims to reduce the occurrence of the so called nuisance alarms. It is a general computerized tool that takes advantage of the control system's built-in functions, and is a first step to an enhanced overall alar

This licentiate thesis consists of two separate studies on educational attainment and returns to education. The first paper, “Ethnic Segregation and Educational Attainment in Sweden”, studies whether youths brought up in ethnically segregated neighbourhoods differ in educational attainment from youths brought up in more affluent neighbourhoods, after controlling for family characteristics. The eth

Sediment pigments as an indicator of water column and benthic processes have become widely used during the last decades. However, the effect of different storage and handling conditions on the accuracy of sediment pigment analyses has not been adequately evaluated. This can potentially make comparisons between studies difficult and, at worst, call into question the validity of some studies. Even t

This paper presents a study of prosodic phras-ing in a non-tonal dialect of Kammu, a Mon-Khmer language spoken in Northern Laos. Prosodic phrasing is seen as correlated with syntactic and informational structures, and the description is made referring to these two lev-els. The material investigated comprises sen-tences of different lengths and syntactic struc-tures, uttered by seven male speakers.
