The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages, using data on Swedish manufacturing firms from 1997 to 2007. First, we investigate the productivity ordering with respect to three international linkages; importing, exporting and investing abroad. Second, we explore whether differences in the productivity ordering ac
We report a combination of physical property and neutron scattering measurements for polycrystalline samples of the one-dimensional spin-chain compound CoV2O6. Heat capacity measurements show that an effective S = 1/2 state is found at low temperatures and that magnetic fluctuations persist up to similar to 6T(N). Above T-N = 6.3 K, measurements of the magnetic susceptibility as a function of T an
Background: Due to its high polymorphism and importance for disease resistance, the major histocompatibility complex (MHC) has been an important focus of many vertebrate genome projects. Avian MHC organization is of particular interest because the chicken Gallus gallus, the avian species with the best characterized MHC, possesses a highly streamlined minimal essential MHC, which is linked to resis
A comparison between the ordinary least-squares estimator and the weighted least-squares estimator when the data set arises from the standard extreme value distribution is provided. Probability plot of the extreme value distribution is applied. A goodness-of-fit test of the standard extreme value distribution is introduced. The percentage points of the test statistic are investigated. The results
Vertebral compression fractures (VCFs) are the most prevalent fractures in osteoporotic patients. The classical conservative management of these fractures is through rest, pain medication, bracing and muscle relaxants. The aim of this paper is to review prospective controlled studies comparing the efficacy and safety of minimally invasive techniques for vertebral augmentation, vertebroplasty (VP)
The study investigates teratogenic risks with ondansetron (Zofran(®)). Data from the Swedish Medical Birth Register combined with the Swedish Register of Prescribed Drugs were used to identify 1349 infants born of women who had taken ondansetron in early pregnancy, 1998-2012. Presence of congenital malformations in the offspring was identified with three national health registers. In a Mantel-Haen
Once prostate cancer becomes castration resistant, cancer cells may rapidly gain the ability to invade and to metastasize to lymph nodes and distant organs. The progression through hormone-dependent to hormone-independent/castration-resistant and metastatic PCa is poorly understood. In this review paper, we provide an overview on the cellular and molecular mechanisms underlying the process of tumo
This paper deals with geographical and organizational patterns of knowledge flows in the media industry of southern Sweden, an industry that is characterized by a strong ?symbolic? knowledge base. The aim is to address the question of the local versus the non-local as the prime arena for knowledge exchange, and to examine the organizational patterns of knowledge sourcing with specific attention pa
This article provides an overview of the management of a displaced hip in children with cerebral palsy and considers surveillance programmes, principles of surgical reconstruction and options for the salvage of an unreconstructable hip in these children.
This article aims to analyse how innovative, individual actions influence the evolution of local industries according to three stages. When discussing the evolution of industries or economies, the concept of path dependency is often a central element. Its vague nature makes it however difficult to be used as an interpretative lens when studying the evolution of local industries. In order to limit
Low hemoglobin concentration is associated with increased mortality, but there is disagreement with regard to the clinical definition of anemia. We aimed to evaluate the prevalence, clinical correlates and association with total and cause-specific long-term mortality across the hemoglobin distribution and for previously proposed definitions of anemia. Blood hemoglobin concentration and mean corpus
Animals relying on a celestial compass for spatial orientation may use the position of the sun, the chromatic or intensity gradient of the sky, the polarization pattern of the sky, or a combination of these cues as compass signals. Behavioral experiments in bees and ants, indeed, showed that direct sunlight and sky polarization play a role in sky compass orientation, but the relative importance of
This paper demonstrates how occurrence, transport and fate of pharmaceuticals at trace levels can be assessed when modelling wastewater treatment systems using two case studies. Firstly, two approaches based on: 1) phenomenology; and, 2) Markov Chains, are developed to describe the dynamics of pharmaceuticals with or without clear administration patterns. Additional simulations also show that sewe
Except for the scattered cephalopod conchs that have given the rock type its name, mollusk fossils are relatively rare in the Middle Ordovician 'orthoceratite limestone' of Sweden. However, an interval in the Darnwilian stands out as being unusually rich in various types of mollusks. Throughout southern Sweden, gastropods became relatively abundant close to the Volkhov-Kunda Baltoscandian Stage bo
Many bacterial pathogens interfere with the contact system (kallikrein kinin system) in human plasma. Activation of this system has two consequences: cleavage of high-molecular-mass kininogen (HK) resulting in release of the potent proinflammatory peptide bradykinin, and initiation of the intrinsic pathway of coagulation. In this study, two species of the Gram-negative anaerobic commensal organism
In many cities of the world, bicycle infrastructure projects are implemented to foster more sustainable transportation systems. However, such projects have often raised questions regarding their public funding, as they entail considerable costs. This paper reviews cost–benefit analysis (CBA) frameworks as these are presently used to assess bicycle infrastructure projects. Specific focus is on the
Dementia has been associated with an increased risk of fractures. These associations may be explained by an impaired cognitive function, as well as comorbid illness and toxic reaction from drugs. To investigate whether cognitive function in young, healthy individuals already affects the risk of fractures, overall cognitive function scores were calculated from four cognitive tests accomplished duri
