Skydd för berättigade förväntningar i svensk förvaltningsrätt? - Negativ rättskraft, EU-rätt och styrning av förvaltningen

En grundläggande fråga i den allmänna förvaltningsrätten är var gränserna ska gå för möjligheten att ändra meddelade beslut. I svensk förvaltningsrätt har denna fråga traditionellt besvarats med hjälp av principer om (förvaltningsrättslig) negativ rättskraft. I EU-rätten har det däremot under inflytande av andra medlemsstaters rättstraditioner utvecklats en unionsrättslig princip om skydd för berä

Search for pair production of vector-like top quarks in events with one lepton, jets, and missing transverse momentum in √s=13 TeV pp collisions with the ATLAS detector

The results of a search for vector-like top quarks using events with exactly one lepton, at least four jets, and large missing transverse momentum are reported. The search is optimised for pair production of vector-like top quarks in the Z() t + X decay channel. LHC pp collision data at a centre-of-mass energy of s=13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to a

Climate warming and land-use changes drive broad-scale floristic changes in Southern Sweden

Land-use changes, pollution and climate warming during the 20th century havecaused changes in biodiversity across the world. However, in many cases, the environmental drivers are poorly understood. To identify and rank the drivers currentlycausing broad-scale floristic changes in N Europe, we analysed data from two vascularplant surveys of 200 randomly selected 2.5 9 2.5 km grid-squares in Scania,

Visual adaptations for mate detection in the male carpenter bee Xylocopa tenuiscapa

Sexual dimorphism in eye structure is attributed to sexual selection in animals that employ vision for locating mates. In many male insects, large eyes and eye regions of higher acuity are believed to facilitate the location of females. Here, we compare various features of male and female eyes in three sympatric carpenter bee species, which include two diurnal species (Xylocopa tenuiscapa and X. l

Computational models for spatiotemporal filtering strategies in insect motion vision at low light levels

We explore a promising new approach to understanding the neural filter mechanisms intermediate in motion processing at low luminance. We carefully account for the known filter properties of early stages of visual processing in a nocturnal moth, and then measured spatiotemporal tuning of higher order neurons. We then use a computational model to identify likely strategies used to reject noisy signa

Biofuels from agricultural biomass – Land use change in Swedish perspective

The Swedish parliament has decided that by 2045, Sweden will not be a net emitter of greenhouse gases. There is also a goal to have a fossil fuel free transport sector by 2030. However, the transport sector is still dominated by fossil fuels and many efforts are needed to lower emissions. Sweden has a relatively high share of biofuels, around 20% of the energy use in domestictransportation. Howeve

Likelihood-free stochastic approximation EM for inference in complex models

A maximum likelihood methodology for the parameters of models with an intractable likelihood is introduced. We produce a likelihood-free version of the stochastic approximation expectation-maximization (SAEM) algorithm to maximize the likelihood function of model parameters. While SAEM is best suited for models having a tractable "complete likelihood" function, its application to moderately comple

Control of Voltage and Damping in Bulk Power Systems

Modern power system is a complex dynamical system and one of the largest man-made systems. With recent driving forces like environmental concerns over air emissions, the modern power system is evolving towards an even more complex system. So it is necessary to handle the current challenges in power systems with simple approaches and avoid adding further complexity as much as possible. Also the imp

Attention and Learning through the Eyes of the Emotional Brain

The present thesis consists of four articles that address cognitive-emotional interactions as measured through eye movements and pupil dilation.Social facilitation-inhibition is an effect that describes changes in performance (enhancement or impairment) when individuals complete tasks in social presence compared to when they perform the same tasks in solitary conditions. Along this line, Paper I a

Hunter-gatherer olfaction is special

People struggle to name odors [1–4]. This has been attributed to a diminution of olfaction in trade-off to vision [5–10]. This presumption has been challenged recently by data from the hunter-gatherer Jahai who, unlike English speakers, find odors as easy to name as colors [4]. Is the superior olfactory performance among the Jahai because of their ecology (tropical rainforest), their language fami

A new challenge for objective uncertainties and the propensity theorist

The paper is concerned with the existence of objective uncertainties. What would it take for objective uncertainties to exist, and what would be the consequences for our understanding of the world we live in? We approach these questions by considering two common theories on how we are to understand the being of propensities and how it pertains to possible outcomes that remain unmanifested.

Juridification and Standardisation: Two Legal Dimensions Influencing Contemporary Child Protection

The aim of this article is to analyse juridification and standardisation as two legal dimensions influencing contemporary child-protection work, and to discuss its implications for practice. We provide a framework for how the concepts of juridification and standardisation might be understood and analytically differentiated, drawing on theoretical discussions within both socio-legal and social work

Disentangling population strategies of two cladocerans adapted to different ultraviolet regimes

Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress at h
