We built machine learning and image analysis tools in order to forecast winter wheat yield based on a rich multi dimensional tensor of agricultural information spanning different scales. This information consists of satellite multi-band images, local soil samples obtained from national databases, local weather as well as field data from 23 farms cultivating winter wheat in southern Sweden. This is

Climate change, biodiversity loss and chemical pollution are planetary-scale emergencies requiring urgent mitigation actions. As these "triple crises" are deeply interlinked, they need to be tackled in an integrative manner. However, while climate change and biodiversity are often studied together, chemical pollution as a global change factor contributing to worldwide biodiversity loss has receive

Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been eva

It is rare to encounter a scientific fact that stirs widespread debate and distrust quite like the matter of climate change.Despite consensus among climate specialists about a theory that is supported by a mountain of facts from the physical, natural, and cultural sciences, the debate continues to be perpetrated by politicians, industrialists, academics, and armchair scientists.When governments re

In this chapter, the author deals with how moral attributes are assigned to particular diasporas or parts of a diaspora, developing his argument both conceptually and with respect to the Rwandan government's construction of diaspora. The Rwandan government does what it can to attract investments and encourage return migration of those abroad who are believed to be supportive of the regime (its 'po

This thesis comprises of four self-contained papers that use both experimental and applied micro-econometric methods to explore different aspects of gender, health, the decisions we make, and the actions we take. In the first paper we investigate changes in psychiatric diagnoses and their income-related inequalities over time in Sweden and attempt to disentangle the development by decomposing chan

Remediation of soil contaminated with cadmium (Cd) and lead (Pb) is critical for tobacco production. Silicon (Si) fertilizer can relieve heavy metal stress and promote plant growth, however, it remains unknown whether fertilization with Si can mitigate the effects of Cd and Pb on tobacco growth and alter microbial community composition in polluted soils. Here we assessed the effect of two organic

This paper proposes a ‘tool for thinking with’: that we can describe the interaction between people and computers, and especially people and developer tools, as a form of conversation. We outline this perspective, construct a work in progress analytical frame, and use it to talk about a couple of different examples and draw implications for future work.

Climate change is an important driver of range shifts and community composition changes. Still, little is known about how the responses are influenced by the combination of land use, species interactions and species traits. We integrate climate and distributional data for 131 butterfly species in Sweden and Finland and show that cumulative species richness has increased with increasing temperature

The EU has a normative character in its foreign policy. While dealing with its relationship with the neighbours, the EU pays attention to exporting its norms. The enlargement policy is evidence of the EU’s normative power. However, from ENP to EaP, the EU seems not so effective in promoting normative changes in the target states. The existing researches lack a deep and comprehensive analysis of th

The properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. Using the fitting code STARFIT, we perform an analysis of 65 bulge metal-poor stars obtained by the EMBLA survey to estimate the IMF (initial mass function) of the very first stars that defined our ga

The purpose of this study is to explore the relationship between organizations, BI Consultancy, value co-creation. The study will examine how the managers use the advice they get from the BI consultants and the information they obtain from the customers to make products and services that are of value to the customers. To achieve this, the study will present an understanding of BI consultancy and v

The European credit default swap (CDS) market has experienced noticeable changes and remarkably developed over the last decades. Today, the relation between the CDS and corporate bond market is a prominent topic in the financial literature. According to the arbitrage argument, the CDS spread equals the corresponding credit spread of a corporate bond. However, substantial deviations between the mar

In recent times there has been a general trend of shifting party competition, with new issues being brought to the foreground. Sweden has undergone multiple changes, both societal and political, paving the way for the issue of law and order to emerge. This thesis examines how the said issue has helped the right-wing populist party, the Sweden Democrats, reinforce their position in the general elec
