In this article we propose a modification of the recently introduced divergence information criterion (DIC, Mattheou et al., 2009) for the determination of the order of an autoregressive process and show that it is an asymptotically unbiased estimator of the expected overall discrepancy, a nonnegative quantity that measures the distance between the true unknown model and a fitted approximating mod
A search for a fermiophobic Higgs boson using diphoton events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV is performed using data corresponding to an integrated luminosity of 4.9 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. A specific benchmark model is considered where all the fermion couplings to the Higgs boson are set to zero and
This review summarises the evidence for the treatment of displaced fractures of the femoral neck in elderly patients. Results from randomised clinical trials and national register studies are presented when available. The advantages of arthroplasty compared with internal fixation are supported by several studies. A number of studies contribute to the discussions of total hip arthroplasty (THA) ver
A new Reference Material (RM) for radionuclides in mussel (Mytilus galloprovincialis) from the Mediterranean Sea (IAEA-437) is described and the results of the certification process are presented. Four radionuclides (K-40, U-234, U-238, and Pu239+240) have been certified, and information values on massic activities with 95% confidence intervals are given for nine radionuclides (Cs-137, Pb-210(Po-2
The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following exte
The effects of climate change are getting evermore severe, especially on the African continent. Actions towards the UN Agenda 2030 for sustainable development are becoming crucial, and one part of this is the energy transition. Africa has some of the world’s best conditions for solar PV and hence it is a viable option for electricity production in Kenya. The aim of this thesis is to understand th
Research question: "How do young women construct and perform aspirational identities through the Clean Girl aesthetic on digital platforms?" Purpose: The purpose of this study is to expand the understanding of how trendy aesthetics on digital platforms like TikTok shape users’ identity construction and self-performance. Theoretical perspective: Two main theoretical fields, aspirational
Germanys transition to high shares of variable renewable energy (VRE) is increasingly ex-posing flaws in the country’s current electricity market design, particularly in its contin-ued use of nationally uniform wholesale pricing. This thesis investigates whether nodal pricing, where electricity prices vary locationally to reflect physical system conditions, can improve market efficiency and suppor
This thesis performs a critical evaluation of the original Cost-Benefit Analysis (CBA) of the Lund tramway project, focusing on its adherence to the then-current Swedish national appraisal guidelines (ASEK 5) and the accuracy of its demand forecasts. An updated demand forecast and monetary valuation of time savings are constructed and compared to the original CBA projections by using empirical pas
Universities are widely understood to be sites of free expression, knowledge-seeking institutions that serve the public good while encouraging personal development of individuals. They typically uphold and communicate institutional integrity and ethics, seeking to encourage open communication, equip students with critical thinking, and foster civil participation. For the Social Sciences, questions

PurposeTo develop an application for the Pentacam HR for the purpose of optimising the accuracy of the diagnosis of progressive keratoconus.MethodsMeasurements were performed on one randomised eye in twenty-five subjects with keratoconus Stage 1-2 according to the Amsler-Krumeich classification on two occasions, three days apart. Four replicate measurements were made by a single examiner on each o
The game plan firms must navigate in the quest of competitive advantage which is changing quickly. More and more firms acknowledge that future prosperity depends on achieving the joint goals of economic, environmental and social sustainability. This understanding has resulted in both firms and actors on the financial markets enhancing their focus on environmental, social and governance dimensions
Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology concepts challenging to teach, and also challenging
In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u
Although the UN concluded, already in 1997, that water would be the most contentious issue of the 21st century, water governance is still confused, nearly everywhere. Even the severe impacts of escalating water bankruptcy and global warming have so far failed to incur a marked improvement in governance systems. The global community has adopted sustainable development as a common vision and guide f
The meshless radial point interpolation method (RPIM) in frequency domain for electromagnetic scattering problems is presented. This method promises high accuracy in a simple collocation approach using radial basis functions. The treatment of high-order non-reflecting boundary conditions for open waveguides is discussed and implemented up to fourth-order. RPIM allows the direct calculation of high
Objective Although important treatment decisions are made in the Emergency Department (ED), conversations about patients’ goals and values and priorities often do not occur. There is a critical need to improve the frequency of these conversations, so that ED providers can align treatment plans with these goals, values, and priorities. The Serious Illness Conversation Guide has been used in other c
The polar region is experiencing one of the most rapid environmental changes driven by atmospheric warming, and feedbacks within the cryosphere. Under such a setting, it is crucial to understand the biogeochemical cycling of the nutrient silicon (Si) in the high latitudes, which is regulating the nutrient supply to polar ecosystems, and is linked to the global carbon cycle via diatom production. H
