Decision trees constructed by ID3-like algorithms suffer from an inability of detecting instances of categories not present in the set of training examples, i.e., they are discriminative representations. Instead, such instances are assigned to one of the classes actually present in the training set, resulting in undesired misclassifications. Two methods of reducing this problem by learning charact
Understanding variation in survival and reproduction is key for conservation and management of bird populations. By compiling and analysing data on hatching success (i.e. proportion of nests with at least one hatched egg) from Common Eider Somateria m. mollissima, Velvet Scoter Melanitta fusca and Red-breasted Merganser Mergus serrator, all breeding on a single island in the Baltic Sea, we demonst
SWENOTECA has since 1998 offered patients with clinical stage I (CS I) nonseminoma, adjuvant chemotherapy with one course of bleomycin, etoposide and cisplatin (BEP). The aim has been to reduce the risk of relapse, sparing patients the need of toxic salvage treatment. Initial results on 312 patients treated with one course of adjuvant BEP, with a median follow-up of 4.5 years, have been previously
We aimed to validate a widely used US prediction model for vaginal birth after cesarean (Grobman et al. [8]) and modify it to suit Swedish conditions.
As the new generation of Information Technology is progressing at a rapid pace, with big data establishing a trend in organisations, integration between systems becomes substantial. In this chapter, we particularly look at information security as a system that has become an essential part of Business Intelligence (BI). BI systems represent one type of decision support system (DSS) with a focus on
Existing knowledge suggests that people's willingness to pay (WTP) for climate change mitigation depends not only on personal characteristics but also on the payment vehicle (PV) that is used to elicit WTP. The aim of this research is to investigate policy-relevant differences in WTP between different PVs to support the design of carbon pri
This thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles. The thesis divides the performance characteristics into three subcategories: The electromagnetic properties, the loss profile and the thermal behaviour of the machines. One separate characterisation met
Context. The first release of astrometric data from Gala will contain the mean stellar positions and magnitudes from the first year of observations, and proper motions from the combination of Gala data with HIPPARCOS prior information (HTPM). Aims. We study the potential of using the positions from the Tycho-2 Catalogue as additional information for a joint solution with early Gala data. We call t
Purpose – The rate of turnover of hospital managers has been high in Sweden. Hospitals are regarded to be difficult to manage, which is connected with different discourses and action logics such as politics, medicine, care and management creating complex conditions for hospital management. The purpose of this paper is to analyse hospital managers' management conditions in conjunction with hospital
An increased regional trade in Africa is often defined as a key tool for a continued development of the continent, but although a numerous of policies aiming at increasing the trade have been adopted, the intra-regional trade remains stubbornly low. Why is that so? In this thesis some of the factors that potentially are affecting the trade are studied in a qualitative design. By conducting case st
This thesis aims to analyze the methods of existing studies on the relationship be- tween energy intensity and economic variables. I study panel data from 42 countries to examine the cointegration between energy intensity and GDP, capital stock, pop- ulation, and CO2 emissions as well as estimate their relationship with a pooled common correlated effects (CCEP) estimator. Then I investigate the he

Thesis Purpose: This study aims to shed light on how the integration of GenAI in political branding shifts voters' trust and perception of political persuasion attempts. Theoretical Perspective: The theoretical lenses of the Persuasion Knowledge Model and the Source Credibility Theory are used to explore how voters perceive and react to political entities using GenAI in their branding strategi
Adopting a postcolonial theoretical framework, drawing specifically on the concepts of imagined geographies and subaltern nationalism, this thesis explores the motivations behind pro-Palestinian activism among the post-accord generation in Northern Ireland since the escalation of the Israeli-Palestinian conflict beginning on October 7, 2023. Based on in-depth interviews, field observations and onl
On the Caribbean island of Hispaniola, two countries share the same environmental and climatic pre-conditions, but show monumental differences in current forest-cover. While tropical forests are covering almost half of the Dominican Republic, Haiti is down to just a few percent. In this thesis, political ecology and earlier research is combined to formulate four hypotheses: colonial history, human
