Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation may be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice tasks that vary the bias induced by random choices, we are able to generate both negative and positive c
BACKGROUND Despite a long interest in the historical fertility transition, there is still a lack of knowledge about disaggregated patterns that could help us understand the mechanisms behind the transition. In previous research the widely held view is that there was a change in the association between social status and fertility in conjunction with the fertility transition, implying that fertility
In this paper the PreAmplifier ShAper (PASA) for the Time Projection Chamber (TPC) of the ALICE experiment at LHC is presented. The ALICE TPC PASA is an ASIC that integrates 16 identical channels, each consisting of Charge Sensitive Amplifiers (CSA) followed by a Pole-Zero network, self-adaptive bias network, two second-order bridged-T filters, two non-inverting level shifters and a start-up circu
This paper focuses on the nexus between nascent entrepreneurship (NE) and inventive activity. It questions how NE affects inventive activity (including innovation and patenting) while analyzing the views and predictions that have used patenting as an indicator of entrepreneurial behavior. Using data on German researchers and controlling for their personal, professional and institutional attributes
In this article I address the significance of semiotic processes supporting early social interaction, communication and learning in the evolution of the modern human niche of infancy and childhood, known to be extended even in comparison with closely related hominin species. Human infancy and childhood is a biocultural niche, embedded within and causally contributing to the expansion and elaborati
The Nordic countries have a quite different urban structure and social systems than the USA. Denmark, Finland, Norway and Sweden may then constitute a critical test of the empirical reach of Richard Florida's much cited creative class thesis beyond its empirical basis in the USA. This paper employs comparative statistics to examine the importance of the quality of place in attracting members of th
Purpose: It is not yet possible to estimate the number of cases required for a beginner to become expert in laparoscopic radical prostatectomy. We estimated the learning curve of laparoscopic radical prostatectomy for positive surgical margins compared to a published learning curve for open radical prostatectomy. Materials and Methods: We reviewed records from 8,544 consecutive patients with prost
Popular Abstract in Swedish Diabetes är en folksjukdom som kännetecknas av förhöjt blodsocker. Sjukdomens förekomst ökar dramatiskt över hela världen och beskrivs ofta som en pandemi. I huvudsak finns det två olika former av diabetes, typ 1 och typ 2. Typ 1 drabbar oftast barn och ungdomar – de insulinproducerande β-cellerna förstörs av kroppens egna immunförsvar. Vid typ 2 diabetes ser sjukdomsbiDefective insulin secretion and insulin resistance are the two hallmarks of Type 2 Diabetes (T2D). The pathophysiology of the disease is not fully understood but genetic susceptibility for the disease is a new major player in the understanding of the underlying mechanisms. T2D research has in recent years invested tremendous efforts in identifying new risk variants for the disease. It has proven t
Conclusion: Alpha B-crystallin was found to be an independent prognostic marker for poor prognosis in oral cavity tumours. For oropharyngeal cancer, alpha B-crystallin had no prognostic value. Objective: The aim of this study was to see if earlier findings of alpha B-crystallin as an independent prognostic marker, and SPARC/osteonectin, PAI-1 and uPA as a prognostic combination for poor outcome in
Software failures in medical devices can lead to catastrophic situations. Therefore, it is crucial to handle software-related risks when developing medical devices, and there is a need for further analysis of how this type of risk management should be conducted. The objective of this paper is to collect and summarise experiences from conducting risk management with an organisation developing medic
Background: Osteoporosis is increasingly recognised as one of the major public health problems throughout the world and has massive socioeconomic implications. It has previously been shown that patients with severe haemophilia and not receiving any prophylactic treatment render a high risk of reduced bone density. Aims: To evaluate Bone Mineral Density (BMD) in patients with haemophilia of differ
Type 2 diabetes mellitus (T2DM) results from interaction between genetic and environmental factors. The worldwide prevalence of T2DM is increasing rapidly due to reduction in physical activity, increase in dietary intake, and the aging of the population. This thesis has focused on dissecting the genetic contribution in T2DM using largescale genomic approaches with a particular emphasis on analysis
A common approach to distributed control design is to impose sparsity constraints on the controller structure. Such constraints, however, may greatly complicate the control design procedure. This paper puts forward an alternative structure, which is not sparse yet might nevertheless be well suited for distributed control purposes. The structure appears as the optimal solution to a class of coordin
Factor I (FI) is a serine protease that inhibits the complement system by cleaving activated C3 and C4 complement proteins, in the presence of cofactors. Mutations in the gene coding for FI have been identified in complete FI deficient- and atypical hemolytic uremic syndrome (aHUS) patients. The mutations were introduced in recombinantly expressed proteins, purified and analyzed in functional ass
The national system of innovation approach has attracted both academics and policy makers. There has been different emphasis laid by those who both originated the concept and developed it further for policy learning applications. From the firm level to the global innovation networks, the varieties and differences in system of innovation functions, activities and factors continue to attract debate
Using first-principles methods, we study theoretically the properties of an individual {Fe-4} single-molecule magnet (SMM) attached to metallic leads in a single-electron transistor geometry. We show that the conductive leads do not affect the spin ordering and magnetic anisotropy of the neutral SMM. On the other hand, the leads have a strong effect on the anisotropy of the charged states of the m
A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb(-1) of root s = 7 TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam l
The diurnal and seasonal occurrence of flight foraging for midges (Chironomidae) by Black-headed Gulls Chroicocephalus ridibundus was studied at a shallow semi-eutrophic lake in South Sweden and their capture rates were recorded. The gulls captured 0.28 chiromids s(-1) (1,012 h(-1)). With a dry mass of 2.08 mg ind(-1) and an energy content of 22.7 kJ g(-1), they achieved an energy intake of c.47 k
We investigate electron transport in disordered Hubbard chains contacted to macroscopic leads, via the nonequilibrium Green's function technique. We observe a crossover of currents and conductances at finite bias which depends on the relative strength of disorder and interactions. We provide a proof that the coherent potential approximation, a widely used method for treating disorder averages, ful
