In classical eyeblink conditioning a subject learns to blink to a previously neutral stimulus. This conditional response is timed to occur just before an air puff to the eye. The learning is known to depend on the cerebellar cortex where Purkinje cells respond with adaptively timed pauses in their spontaneous firing. The pauses in the inhibitory Purkinje cells cause disinhibition of the cerebellar
The complexity status of the minimum r-star cover problem for orthogonal polygons had been open for many years, until 2004 when Ch. Worman and J. M. Keil proved it to be polynomially tractable (Polygon decomposition and the orthogonal art gallery problem, IJCGA 17(2) (2007), 105-138). However, since their algorithm has (O) over tilde (n(17))-time complexity, where (O) over tilde (.) hides a polylo
In the search for the fully aligned 27(-) state in Nd-140 predicted by cranked Nilsson-Strutinsky calculations, new close-to-spherical high-spin states have been discovered. Both the close-to-spherical and the triaxial calculated states are in good agreement with the experimental results, supporting the existence of shape coexistence up to very high spins. Shell-model calculations using a newly de
This thesis deals with driving forces for CSR reporting in China. More and more international companies have published their CSR reports under the concern of sustainable development. Chinese companies are facing the environmental and social challenges in China today. CSR reporting has been taken as a sustainable development strategy by the Chinese Central Government and the pioneering Chinese comp
VIX, published by the Chicago Board Options Exchange, is a well known implied volatility estimator. In this paper we assess its capability to be used as a sentiment indicator, and to give signals for a short term investment strategy. It will be proved and discussed how VIX-based strategies – also known as “Contrarian” strategies – can be effective as they lead to higher returns than the market. We
In 1996, Robert A. Haugen and Nardin L. Baker published a study where they had made a multi-factor model based on micro-variables on the American stock market between 1979 and 1993. In testing the model on the examined period they made an average annual return of 30,9 percent. They also tested the model on several other markets around the world with similar results. This study is a somewhat simple
The precise valuation and correct assessment of the value of imported goods should be preceded by determining the value of imported goods for Customs purposes. The provisions regulating the Customs valuation are overlapped and complicated; the reason which prompted the Author, through this paper, to eliminate this overlaps and simplify the complexity, using a new approach represented by reclassify
This thesis discusses whether Corporate Social Responsibility (CSR) can affect a company’s, and consequently a portfolio’s, stock market performance. The study presupposes the regular assumptions drawn from CAPM. By creating three different portfolios, consisting of companies with similar financial characteristics, but with different levels of CSR-involvement, we investigate how the CSR-factor may
The debate on Nordic defense cooperation has surged in the recent year as a result from a perceived shift in the security environment. The study focuses on the five Nordic states; all of them committed to different security communities and yet engaged in cooperative measures with each other. With the question of exploring the prerequisites for a possible deepening of the Nordic defense cooperatio

When experience is insufficient or not present at all, making decisions becomes difficult. Capability assessments are tools to inform decisions in all situations regarding risk management, but the use of them in Sweden is discussed. With experiments made in the microworld MikroRisk, conclusions can be made about the investment patterns induced by a capability assessment under the conditions of bot
Society faces multiple and interconnected crises that require transformation. Education has long been theorized as key to transformation, yet an important driver of transformation, imagination, is marginalised within pedagogical approaches to sustainability. This thesis examines Beyond the Fossil Era (BFE), a pedagogy that invites learners to become co-creators of a speculative museum looking back
The violation of baryon number, B, is a vital component of a process promoting the excess of matter over antimatter, as it is necessary to explain the baryon imbalance observed in the universe. Since experimental evidence for such an occurrence has yet to be discovered, the HIBEAM-NNBAR experiment, at the European Spallation Source facility, is a proposed two-stage program aimed at expanding the c
The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. The first provides an alternative algorithm for the evaluation of diagrams, where helicity amplitudes are obtained by combining
The EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron
The growing importance of organisations becoming more sustainable has reached a crucial point. To aid the journey of becoming more sustainable information systems and specifically business intelligence is an appropriate solution to help manage and measure sustainable development. However previous research suggests the use of business intelligence in the context of sustainability is not as prevalen
