This article is a case study of the contacts between the music sector in Sweden and the GDR in the 1970s, 1980s and 1990s. The case is the activities of the East-German musicologist and music administrator Gerd Schönfelder (1936–2000) in Sweden at that time, and the debate that arose in the early 1990s when he was accused of having worked for the East German security service, Stasi. The purpose is

In this article I explore the different and changing meanings of the concept “privat” in records from the Swedish Riksdag (state assembly) from the sixteenth to the beginning of the eighteenth century. I analyze how the concept was used in different contexts, such as questions concerning e.g. private and public religious practices, relations between individuals and communities, and relations betweIn this article I explore the different and changing meanings of the concept “privat” in records from the Swedish Riksdag (state assembly) from the sixteenth to the beginning of the eighteenth century.

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of

We report post-compression of 1.2 ps pulses into the few-cycle regime via multi-pass spectral broadening. We achieve compression factors of 40 in single and 93 in a dual stage scheme using a compact setup.

We present an experimental method capable of characterizing spatio-temporal dynamics of a femtosecond filament v ia F ourier t ransform i nterferometry, p roviding a three-dimensional reconstruction of the driving pulse, while scanning along the entire length of the filament.

We demonstrate a novel timing tool for Free-Electron Lasers to determine the delay between an attosecond pulse train and infrared pulse with sub-optical-cycle resolu-. tion.

K2-19 hosts a planetary system composed of two outer planets, b and c, with size of 7.0 ± 0.2 R⊕ and 4.1 ± 0.2 R⊕, and an inner planet, d, with a radius of 1.11 ± 0.05 R® A recent analysis of Transit-Timing Variations (TTVs) suggested b and c are close to but not in 3:2 mean motion resonance (MMR) because the classical resonant angles circulate. Such an architecture challenges our understanding of

Solceller är en eftertraktad teknik för att mildra de globala klimatförändringarna. Samtidigt finns det en växande oro att denna teknik är både skadlig för miljön och orättvist fördelad i världsekonomin. Forskare och miljöaktivister är oeniga i frågan om en global maktrelation är ofrånkomligt kopplad till solcellsteknik. Denna avhandling undersöker i vilken utsträckning de globala sociala och mateSolar photovoltaic (PV) technology is one of the most favored means of mitigating climate change. At the same time, there is a growing concern over how this technology is both environmentally harmful and unevenly distributed in the world economy. Researchers and environmentalists differ on whether a global relation of power is inherent in solar technology. This thesis investigates to what extent t

Testing of autonomous systems is extremely important as many of them are both safety-critical and security-critical. The architecture and mechanism of such systems are fundamentally different from traditional control software, which appears to operate in more structured environments and are explicitly instructed according to the system design and implementation. To gain a better understanding of a

This study aims at exploring multimodal discursive images of academic teachers from 1950 and 1980 in Sweden. Using a discourse-historical approach, linguistic and visual data were analysed in a govern- ment report and three media sources related to a single Swedish university. Findings reveal how four dominant ideologies of academic teaching contributed to constructing eight discursive images of t

We give an expression for the Garsia entropy of Bernoulli convolutions in terms of products of matrices. This gives an explicit rate of convergence of the Garsia entropy and shows that one can calculate the Hausdorff dimension of the Bernoulli convolution νβ to arbitrary given accuracy whenever β is algebraic. In particular, if the Garsia entropy H(β) is not equal to log(β) then we have a finite t
