Firm performance in the periphery: on the relation between firm-internal knowledge and local knowledge-spillovers

Firm performance in the periphery: on the relation between firm-internal knowledge and local knowledge spillovers. Regional Studies. One of the most established arguments in regional studies is that knowledge dynamics shape thegeography of economic activities and, more specifically, that knowledge-intensive activities benefit from collocation due to knowledge spillovers, local buzz and access to l

Adrenomedullin and endothelin-1 are associated with myocardial injury and death in septic shock patients

AbstractBackgroundAdrenomedullin and endothelin-1 are hormones with opposing effects on the cardiovascular system. Adrenomedullin acts as a vasodilator and seems to be important for the initiation and continuation of the hyperdynamic circulatory response in sepsis. Endothelin-1 is a vasoconstrictor and has been linked to decreased cardiac performance. Few studies have studied the relationship betw

Molecular mechanisms of brain ischemia and its protection

Ischemia is defined as a reduction in blood flow to a level that is sufficient to alter normal cellular function. Brain tissue is highly sensitive to ischemia, such that even brief ischemic periods in neurons can initiate a complex sequence of events that may ultimately culminate in cell death. Stroke and cardiac arrest induce the cessation of cerebral blood flow, which can result in brain damage.

Customer-based brand equity and human resource management image : Do retail customers really care about HRM and the employer brand?

Purpose: The purpose of this study is to investigate the relationship between an organization’s human resource management (HRM) image and its customer-based brand equity. Research into HRM in relation to branding has mostly dealt with how to attract and maintain employees through employer branding. The present study attempts to link HRM directly to marketing and branding aimed at customers as an a

How to assess transport in animals?

The general principles for assessing solute and fluid transport across the peritoneum in animal models are not different from those in human studies. Animal models allow for extensive standardization of experimental conditions and also for sampling of peritoneal tissues for analysis. The present review will focus on (1) the scaling issue between various species, (2) how to measure intraperitoneal

Association between shift work history and performance on the trail making test in middle-aged and elderly humans : The EpiHealth study

Shift work has been proposed to promote cognitive disturbances in humans; however, conflicting evidence is also present. By using data from 7143 middle-aged and elderly humans (45-75 years) who participated in the Swedish EpiHealth cohort study, the present analysis sought to investigate whether self-reported shift work history would be associated with performance on the trail making test (TMT). T

Computing the structural influence matrix for biological systems

We consider the problem of identifying structural influences of external inputs on steady-state outputs in a biological network model. We speak of a structural influence if, upon a perturbation due to a constant input, the ensuing variation of the steady-state output value has the same sign as the input (positive influence), the opposite sign (negative influence), or is zero (perfect adaptation),

Set invariance for delay difference equations

This paper deals with set invariance for time delay systems. The first goal of the paper is to review the known necessary or sufficient conditions for the existence of invariant sets with respect to dynamical systems described by discrete-time delay difference equations (dDDEs). Secondly, we address the construction of invariant sets in the original state space (also called D-invariant sets) by ex

On the LPV control design and its applications to some classes of dynamical systems

In this chapter, a control design approach based on linear parametervarying (LPV) systems, which can be exploited to solve several problems typically encountered in control engineering, is presented. By means of recent techniques based on Youla–Kucera parametrization, it is shown how it is possible not only to design and optimize stabilizing controllers, but also to exploit the structure of the Yo

Piecewise-linear Lyapunov functions for structural stability of biochemical networks

We consider the problem of assessing structural stability of biochemical reaction networks with monotone reaction rates, namely of establishing if all the networks with a certain structure are stable regardless of specific parameter values. We investigate stability by absorbing the network equations in a linear differential inclusion and seeking for a polyhedral Lyapunov function proper to the con

Female nutritional state affects the rate of male incubation feeding in the pied flycatcher Ficedula hypoleuca

Male pied flycatches Ficedula hypoleuca regularly feed their mates during incubation. By experimentally supplying some females with extra food we studied how the female's nutritional state affected her incubation schedule and the rate at which her mate fed her. Females that received extra food spent more time on the nest and shorter periods away from it, compared with control females. This suggest

Twelve months of electronic monitoring (MEMS®) in the Swedish COAST-study : a comparison of methods for the measurement of adherence in schizophrenia

The primary aim was to compare objective and subjective measures of adherence in a naturalistic cohort of schizophrenia outpatients over 12 months between October 2008 and June 2011. Antipsychotic medication adherence was monitored in 117 outpatients diagnosed with schizophrenia or schizophrenia-like psychosis according to DSM-IV criteria in a naturalistic prospective study. Adherence was determin

Identification of QTL on chromosome 18 associated with non-coagulating milk in Swedish Red cows

Non-coagulating (NC) milk, defined as milk not coagulating within 40 min after rennet-addition, can have a negative influence on cheese production. Its prevalence is estimated at 18% in the Swedish Red (SR) cow population. Our study aimed at identifying genomic regions and causal variants associated with NC milk in SR cows, by doing a GWAS using 777k SNP genotypes and using imputed sequences to fi

Taxation of Partnership - Economic national reports for the Nordic Tax Research Council's annual meeting, 2015 in Aarhus

This joint report includes economic national reports on the taxation of partnership in the Nordic countries, except Denmark. The general contents of these reports are summarized and thoroughly analyzed in Anna Holst Birket-Smith’s General report, published in this issue of the NTaxJ. For additional information, details on legislative measures etc. we find it important, however, to also publish the

Abolished angiogenicity and tumorigenicity of Burkitt lymphoma by interleukin-10

Because of its immunosuppressive properties, interleukin-10 (IL-10) is thought to play an important role in a number of human disease states, including inflammation, autoimmunity, and transplant rejection. In this study, we demonstrate that introduction of human or viral IL-10 genes into Burkitt's lymphoma cells markedly reduced their ability to grow as subcutaneous (sc) tumors in SCID mice. In vi

Association of erythroid transcription factors : complexes involving the LIM protein RBTN2 and the zinc-finger protein GATA1

The RBTN2 LIM-domain protein, originally identified as an oncogenic protein in human T-cell leukemia, is essential for erythropoiesis. A possible role for RBTN2 in transcription during erythropoiesis has been investigated. Direct interaction of the RBTN2 protein was observed in vivo and in vitro with the GATA1 or -2 zinc-finger transcription factors, as well as with the basic helix-loop-helix prot

Functional diversity of LIM proteins : amino-terminal activation domains in the oncogenic proteins RBTN1 and RBTN2

The RBTN1 and RBTN2 genes are activated by distinct translocations involving chromosome 11 in some T cell acute leukaemias. The RBTN proteins belong to the LIM family which comprises proteins with one, two or three cysteine-rich LIM domains, sometimes together with homeodomains or protein kinase domains. The RBTN1 and RBTN2 proteins comprise only tandem LIM domains. We report that RBTN1 and RBTN2

Signal-to-noise criterion for free-propagation imaging techniques at free-electron lasers and synchrotrons

We propose a signal-to-noise criterion which predicts whether a feature of a given size and scattering strength, placed inside a larger object, can be retrieved with two common X-ray imaging techniques: coherent diffraction imaging and projection microscopy. This criterion, based on how efficiently these techniques detect the scattered photons and validated through simulations, shows in general th
