The ESA space astrometry mission Gala, due for launch in early 2012, will in addition to its huge output of fundamental astrometric and astrophysical data also provide stringent tests of general relativity. In this paper we present an updated analysis of Gaia's capacity to measure the PPN parameter gamma as part of its core astrometric solution. The analysis is based on small-scale astrometric sol
Difficulties in attracting student teachers have resulted in research focusing on student teachers' motives for studying to join the profession. Because previous findings are mixed, the first aim of this study was to explore motives for students to become teachers. A second aim was to explore the relationship between teachers' motives and their academic engagement and dropout rates at the end of t
A key challenge in developing sustainable cities is establishing circular infrastructure systems. Decentralised urban water management solutions (DUWMS) are a case in point: Innovative DUWMS that allow recycling the water, heat, energy, or nutrients contained in wastewater locally are currently emerging in cities around the world. These systems could significantly enhance cities’ water resilience
This study attempts to examine the existence and development of price differences in the car sector in Europe. The time period is between 1995, the year of the Swedish entrance in the European Union, and 2003. The study is based on data supplied by the European commission, on a bi-annual basis. Both price differences in general in the EU, and price differences between Sweden and other countries in
The past ten years have seen the steady escalation of attempts tosecuritise the EU which, for good or for bad, are now beginning tosucceed. Across Europe the EU is fast becoming a convincing reason forgroups to mobilise in protest and action - from Copenhagen to Nice toGothenburg the EU has become a synonym for ‘threat’. As this paper willexplore, the securitisation of the EU is occurring as it be
Acta Radiologica celebrates its 100th anniversary in 2021. In this article, the foundation of the journal and its editors are described. During 100 years, the manuscript structure changed from single-author verbose monographs to multi-author collaborations on statistically analyzed research subjects. The authorship changed from purely Nordic authors to a truly international cadre of authors, and t
• Climate finance coordination challenges reflect political differences, including divergent interests among ministries involved in the governance of multilateral climate funds.• Differences in the histories and governance of the Climate Investment Funds (CIF) and Green Climate Fund (GCF) – two key multilateral climate funds – shape debate on their respective advantages and future roles.• The mult
An important challenge in the design and implementation of self-optimizing systems is that of finding a model that maps changes in a tunable parameter (or “knob”) into an effect on the performance, power, or energy, of the overall system. This paper describes ARPE (Analyzing the Relationship between Parameters and Effectors), an open source tool to analyze the effect of parameter changes on the be
In this study artificial neural networks (ANNs) are utilized for time series forecasting. Analyzed time series includes two Google AdWords metrics and revenue for an e-commerce. Classes of ANNs included in the analysis are feedforward multilayer perceptron’s and two types of recurrent neural networks (RNNs), specifically Jordan- and Elman neural networks. Since ANNs lack econometric interpretation
With the rise of Internet of Things (IoT) accessories such as network attached cameras, light bulbs and thermostats are all constantly connected to the Internet and security concerns must be taken seriously. If a bug exists in an application it could be hacked by a malicious adversary that then could harm the underlying system, leak information or attack other devices or networks. Applications sho
This essay connects to an ongoing discussion and debate on the usefulness and accuracy of the theories and the conceptual apparatus developed by the French theorist Henri Lefebvre. From an analytical reading of Lefebvre’s book The Urban Revolution, I make an original interpretation of Lefebvre’s arguments by tracing them back to Hegel’s syllogism and Marx’s two departments of social reproduction.
The purpose of this study is to investigate if there is a difference in the short-term announcement effects of equity private placements depending on the relationship of the investor with the issuing firms in terms of information asymmetry and agency conflicts. An event study is conducted to study if there are abnormal returns. The abnormal returns will be used as the dependent variable in a reg
In this thesis three different methodologies to convert Point-in-Time (PIT) probability of default (PD) to Through-the-Cycle (TTC) PD are applied on a sample of large Danish firms for the period 2005-2014. These kind of methodologies are important for preventing pro-cyclicality in the capital requirement, i.e. how much capital banks need to hold in order to cope with unexpected losses. The methods
