Birds have evolved a mobile lifestyle in which vision is of major importance when controlling movements, avoiding predators, finding food and selecting mates. Birds have extraordinary colour vision and have been suggested to perceive the linear polarisation of light. Behavioural experiments support this idea, but still the exact physiological mechanism involved is not known. The twilight period, w
Absolute environmental sustainability assessments quantify the environmental impacts of human activities in relation to ecological carrying capacities. Such assessments necessitate the application of sharing principles to allocate shares of carrying capacity to actors and activities at different scales, including products, companies, sectors, and countries. This can help decision-makers set target
With simultaneous policy and scholarly attention to the pollution crisis and the climate crisis, there is growing recognition that the two are intimately interconnected through the demand for oil, gas, and coal generated by synthetic materials. Drawing on theoretical resources from international political economy and beyond, we show how petrochemicals sit at the intersection of a number of the pri
Vårdvalet blev obligatorisk inom den svenska primärvården år 2010, vilket utökade patienternas valmöjligheter och gjorde det möjligt för privata vårdgivare att etablera sig med offentlig finansiering. Även om vårdvalsreformens påverkan på primärvårdens utformning är allmänt erkänd, är resultaten gällande dess effekter på jämlikhet i vårdutnyttjande delvis motsägelsefulla.Det överordnade syftet med
Phosphorus (P) is a critical macronutrient for plant growth, often limiting plant production in areas where plant demand is higher than soil supply. In contrast to nitrogen (N), P cannot be sourced from the atmosphere; therefore, where it is rare, it becomes a strong constraint on primary production. Due to this, most dynamic global vegetation models (DGVMs) are incorporating a prognostic P cycle
This thesis consists of three self-contained papers that use methods in applied microeconometrics to study questions involving gender, housing, and peers.In the first paper, we examine whether gender gaps in labor market outcomes are driven by differences in productivity. Using the as-if random allocation of job seekers to caseworkers at the Swedish Employment Agency, we are able to calculate prod
The aim of this chapter is to contribute to the knowledge on the organization of work in the textile supply chain on the eve of industrialization. To do this we make a case-study of Herman Krutmeijers Hosiery and textile factory which was active in Malmö between 1768 and 1784. We are especially interested in the role of the spinners and try to answer three specific questions: what did the organiza
Power Factor Correction (PFC) converters are essential in designing any charging architecture, regardless of the battery's capacity and the application. Nevertheless, power converters, having continuous output current features, are widely used for battery charging applications. In contrast, converters with continuous input current characteristics exhibit better PFC performance. The Cuk converter c
What are the heaviest elements that can exist in Nature or be created on Earth? Does an ‘Island of Stability’ exist beyond uranium? Questions like these are often asked in connection with Long Range Plans of nuclear physics communities or large-scale accelerator facilities. Information on the chemical and physical properties of superheavy elements (Z>103) or nuclei is notoriously difficult to coll
The mechanisms of glass transitions and the behavior of small solute molecules in a glassy matrix are some of the most important topics of modern thermodynamics. Water plays an important role in the physical and chemical stability of lyophilized biologics formulations, in which glassy carbohydrates act as cryoprotectants and stabilizers. In this study, sorption calorimetry was used for simultaneou
