The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal acti
Most stars form in a clustered environment. Both single and binary stars will sometimes encounter planetary systems in such crowded environments. Encounter rates for binaries may be larger than for single stars, even for binary fractions as low as 10-20 per cent. In this work, we investigate scatterings between a Sun-Jupiter pair and both binary and single stars as in young clusters.We first perfo
Context. The detection of a super-Earth and three mini-Neptunes transiting the bright (V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and ground-based light curves. Aims. We perform a first characterisation of the HD 108236 planetary system through high-precision CHEOPS photometry and improve the transit ephemerides and system parameters. Methods. W
The thesis is a collection of four papers on Greek street art (specifically situated in the city of Athens) with a focus on metaphors and narratives. The overall aim guiding this thesis is to explore how street art in times of crisis can represent sociopolitical issues and in what ways these messages can be conveyed. By using the perspective of cognitive semiotics to address this, a parallel aim i
The nexus between the environment, natural resources and (armed) violence has been researched since the end of the nineties, however major theoretical and empirical gaps still exists in research on the precise role of nature or the natural environment during post-conflict and/or peacebuilding, particularly in relation to those countries that have undergone internal armed conflict.This paper presen
The concept of individual choice is a fundamental aspect when explaining and anticipating behavioural interactions with, and responses to, static and dynamic travel conditions in public transport (PT) systems. However, the empirical rounding of existing models used for forecasting travel demand, which itself is a result of a multitude of individual choices, is often insufficient in terms of detai
e concept of ecosystem services was originally developed to illustrate the benefits that natural ecosystems generate for society and to raise awareness for biodiversity and ecosystem conservation. In this article we identify major challenges and opportunities for ecologists involved in empirical or modeling ecosystem service research. The first challenge arises from the fact that the ecosystem ser
Formulating and implementing a new strategy may be a challenging task, especially if it alters the way in which a company has operated and positioned itself before. This may be particularly true for companies within the forest industry, like manufacturers of paper packaging products, pursuing differentiated customer value and innovative solutions where, traditionally, success has been measured in
This dissertation reports on a study of reform processes in public organisations. It describes how two municipalities planned and attempted the introduction of the purchaser-supplier model. This type of reform reflects one important contemporary idea - that of the market as an all-encompassing institution. The study focuses on the very process of reforming, with the aim of providing an alternative
Weathering of soil minerals is important for the recovery from acidification and for the sustainability of forestry. However, there is still substantial uncertainty about its absolute rate. This study presents a harmonized comparison of field weathering rates estimated with the mechanistic model PROFILE and the depletion method for 16 intensively sampled soil profiles across Sweden representing di
Flow injection analysis provides a convenient platform for the use of biosensors in the monitoring of bio-processes. A major requirement in bioprocess monitoring is real time information about various process parameters like concentration of products and substrates, flow rates, and injection volumes. Depending on the application, the monitoring requirements vary and this results in a need for diff
Background: The objective was to understand patients' views of treatment after acute anterior cruciate ligament (ACL) injury, and their reasons for deciding to request surgery despite consenting to participate in a randomised controlled trial (to 'cross-over'). Methods: Thirty-four in-depth qualitative interviews were conducted with young (aged 18-35), physically active individuals with ACL ruptur
The article explores the relation between i) the attitudes of students towards digital pedagogical characters and ii) their learning style as separate versus connected thinkers, a learning style dimension which regards individual's approach towards the social dimensions of knowledge. Ninety 12-15 year old students participated in the study in which they were presented with a scenario-based multime
Second-order scalar-relativistic Douglas-Kroll-Hess density functional calculations of the electric field gradient, including an analytic correction of the picture change error, were performed for 34 tin compounds of which molecular structures and Sn-119 Mossbauer spectroscopy parameters are experimentally known. The components of the diagonalized electric field gradient tensor, V-xx,V-yy, V-zz, w
Resistivity in horizontal boreholes can give useful detailed information about the geological conditions for construction in rock, i.e. in front of a tunnel bore machine. This paper is an attempt to identify a suitable methodology for an effective measuring routine for this type of geophysical measurements under actual construction site conditions. Prior to any measurements numerical modelling was
Popular Abstract in Swedish Conodonter är en numera utdöd grupp havslevande djur vars systematiska ställning länge varit föremål för debatt. De var i det längsta kända enbart genom sina millimeterstora, kalciumfosfatiska element, vilka vi idag vet satt i djurens munhåla. Sådana conodontelement beskrevs för första gången 1856 av Christian Heinrich Pander, men det skulle dröja närmare 130 år innan dThis thesis deals with conodont biostratigraphy and palaeoecology in the Darriwilian (Middle Ordovician) of Baltoscandia, with focus on limestone strata showing traces of the ~ 470 Ma L-chondrite parent body break-up. The evidence for this cosmic event includes abundant centimeter to decimeter-sized fossil meteorites and elevated levels of sediment-dispersed extraterrestrial L-type chromite found
The ADVEX project involved conducting extensive advection measurements at three sites, each with a different topography. One goal of the project was to measure the [CO2] balance under night-time conditions, in an attempt to improve NEE estimates. Four towers were arranged in a square around a main tower, with the sides of the square about 100 m long. Equipped with 16 sonic anemometers and [CO2] sa
We are currently witnessing an age of migration and globalisation. The growing hybridisation of societies creates continuous discussion and debate concerning who belongs and who does not. The media are traditionally seen to play an important role in this dispute through representational and discursive practices that contribute to our ideas about ‘us’ and ‘them’, simultaneously affecting the constr
Människohandel för sexuella ändamål är ett växande globalt problem. I samband med pandemin har den svenska gränspolisen rapporterat in misstankar om ökad människohandel till Sverige från länder med en mer omfattande nedstängning. Offren för denna typ av exploatering är i regel unga kvinnor som är på flykt från utsatta situationer i sina hemländer. I Sverige möter de en efterfrågan på billiga sexuHuman trafficking for the purpose of sexual exploitation is a growing global issue. In connection with the pandemic, the Swedish Border Police have reported suspicions of increased human trafficking to Sweden from countries with a more extensive lock-down. The victims of this type of exploitation are usually young women fleeing vulnerable situations in their home countries. In Sweden, they meet a
The aim of the study was to analyze if parents were aware of the white norm in Swedish society and if it affected them in any way. Through semi structured interviews at a children's center in the south of Scania, we ascertained the parents' perception of the white norm through the experiences that they shared. We also interviewed a preschool pedagogical teacher to gain their perspective of
