The growth effects of institutional instability
We study the effects of institutional instability on growth. Using principal components analysis, we construct measures of institutional quality and instability from the political risk index of the International Country Risk Guide. A panel-data analysis of 132 countries during 1984–2004 reveals that institutional quality, especially with regard to the legal system and the protection of property ri
Joking aside: Theorizing laughter in organizations
Humour is becoming an increasingly prevalent topic in organization studies. On the one hand, humour is said to enable workers to undermine management control; on the other hand, humour is said to provide managers with a resource for ensuring compliance with corporate objectives. This paper seeks to challenge the duality found in the literature between rebellious and disciplinary forms of humour by
Number of Nexin Links Detectable at Standard Electron Microscopy of Normal Human Nasal Cilia and at Nexin Link Deficiency.
Abstract Background: Eleven years ago we had described three patients with missing nexin links as a possible cause of primary ciliary dyskinesia (PCD). The assumption was substantiated last year by finding a mutation in these patients. Materials and Methods: We counted the nexin links, inner (IDA) and outer (ODA) dynein arms and microtubuli in each of, if possible, 50 cilia in 41 patients with nor
Noninvasive estimation of organization in atrial fibrillation as a predictor of sinus rhythm maintenance.
Previous studies indicate that the predictive value of atrial fibrillatory rate in patients undergoing cardioversion of atrial fibrillation (AF) of long duration is limited. The present study investigates signal entropy in this setting. Standard 12-lead electrocardiograms (ECGs) were recorded from 66 consecutive patients with AF undergoing cardioversion and sample entropy estimated. Patients were
T wave alternans in experimental myocardial infarction: Time course and predictive value for the assessment of myocardial damage.
BACKGROUND: T-wave alternans (TWA) is associated with prognosis after myocardial infarction (MI), however its link to the extent of ischemic injury has not been clarified. We analyzed the course of TWA and its relation to myocardial damage in experimental myocardial infarction. METHODS: In 21 pigs, infarction was induced by 40-minute long balloon inflation in LAD under continuous 12-lead ECG monit
RNA sequencing: current and prospective uses in metabolic research.
Previous global RNA analysis was restricted to known transcripts in species with a defined transcriptome. Next generation sequencing has transformed transcriptomics by making it possible to analyse expressed genes with an exon level resolution from any tissue in any species without any a priori knowledge of which genes that are being expressed, splice patterns or their nucleotide sequence. In addi
Improved microbial electrocatalysis with osmium polymer modified electrodes.
Using the well-known exoelectrogen Shewanella oneidensis MR-1, an osmium redox polymer modified anode exhibited ca. 4-fold increase in current generation. Additionally, a significant decrease in the start-up time for electrocatalysis was observed. The findings suggest that the inherent extracellular electron transfer capabilities of electrogens coupled with such polymers could enhance electrocatal
Architecture of the Yeast Mitochondrial Iron-Sulfur Cluster Assembly Machinery: The Sub-Complex Formed by the Iron Donor, Yfh1, and the Scaffold, Isu1.
The biosynthesis of Fe-S clusters is a vital process involving the delivery of elemental iron and sulfur to scaffold proteins via molecular interactions that are still poorly defined. We reconstituted a stable, functional complex consisting of the iron donor, Yfh1, and the Fe-S cluster scaffold, Isu1, with 1:1 stoichiometry, [Yfh1]24 ·: [Isu1]24. Using negative staining transmission EM and single
Less pronounced response to exercise in healthy relatives to type 2 diabetics compared to controls.
Healthy first-degree relatives with heredity of type 2 diabetes (FH+) are known to have metabolic inflexibility when compared to subjects without heredity for diabetes (FH-). In this study, we aimed to test the hypothesis that FH+ individuals have an impaired response to exercise compared to FH-. 16 FH+ and 19 FH- insulin sensitive men similar in age, VO2peak and BMI completed an exercise interven
Vision and the light environment.
Almost all animals, no matter how humble, possess eyes. Only those that live in total darkness, such as in a pitch-dark cave, may lack eyes entirely. Even at tremendous depths in the ocean - where the only lights that are ever seen are rare and fitful sparks of bioluminescence - most animals have eyes, and often surprisingly well-developed eyes. And despite their diversity (there are currently ten
Thioredoxin targets of the plant chloroplast lumen and their implications for plastid function
The light-dependent regulation of stromal enzymes by thioredoxin (Trx)-catalysed disulphide/dithiol exchange is known as a classical mechanism for control of chloroplast metabolism. Recent proteome studies show that Trx targets are present not only in the stroma but in all chloroplast compartments, from the envelope to the thylakoid lumen. Trx-mediated redox control appears to be a common feature
Skin pentosidine and telomere length do not covary with age in a long-lived seabird
The questions about why and how senescence occurs in the wild are among the most pertinent ones in evolutionary ecology. Telomere length is a commonly used marker for aging, while other biomarkers of aging have received considerably less attention. Here we studied how another potent indicator of aging-skin pentosidine concentration-relates to age and blood telomere length in a long-lived seabird w
Characterization of nitrotyrosine as a biomarker for arthritis and joint injury
Objectives: To characterize the utility of nitrotyrosine (NT) as a biomarker for arthritis and joint injury. Design: Synovial fluid, plasma, and urine from patients diagnosed with osteoarthritis (OA), rheumatoid arthritis (RA), anterior cruciate ligament (ACL) injury, meniscus injury and pseudogout, and knee-healthy volunteers were analyzed for concentrations of NT, nitrate and nitrite (NOx), matr
How swift are swifts Apus apus?
Swifts Apus apus are renowned for their fast flight manner which has fascinated people in all times. However, previous studies of swifts in flight during migration and roosting flights have shown that the birds operate over a narrow range of flight speeds compared with most other birds studied. In this study we have focused on the special flight behavior often called 'screaming parties'. During th

Content Analysis of Four Fear of Falling Rating Scales by Linking to the International Classification of Functioning, Disability and Health.
OBJECTIVE: To gain a deeper understanding of the content of 4 fear of falling (FOF) rating scales by linking them to the International Classification of Functioning, Disability and Health (ICF). DESIGN: Linking study according to the ICF linking rules. SETTING: Not applicable. PATIENTS: Not applicable. METHODS: The rating scales were the Falls Efficacy Scale-International (FES-I), the Swedish vers
Characterization and validation of the frequency-modulated continuous-wave technique for assessment of photon migration in solid scattering media
The frequency-modulated continuous-wave (FMCW) technique, based on the beat signal of a Mach– Zehnder interferometer employing a frequency-ramped light source, is studied for solid scattering media applications. The method is used to evaluate the mean time-of-flight (MTOF) of light traveling in scattering media, specifically polystyrene foams. We assume that each the time-of-flight (TOF) time corr
Stakeholder dynamics in the EU forest energy sector: key issues to manage and ways forward
EU forest biomass demand is increasing rapidly under policy stimuli, as biofuels are important for EU utilities to reach EU 2020 renewables goal. The import of large amounts will be required, but stakeholders have sustainability concerns. Utilities are adopting self-regulatory certification schemes to reduce stakeholder pressures but the interplay between these efforts, stakeholder and policy dyna
Paleomagnetism and U-Pb age of the 2.4 Ga Erayinia mafic dykes in the south-western Yilgarn, Western Australia: Paleogeographic and geodynamic implications
We present results from a paleomagnetic study of the previously undated Erayinia dykes intruding the south-western Yilgarn Craton. The U-Pb TIMs baddeleyite age of these dykes is now 2401 +/- 1 Ma, which is about 10 m.y. younger than the 2418-2410 Ma Widgiemooltha dyke swarm. The paleomagnetic study isolated a stable primary remanence with steep downward direction, and the paleomagnetic pole (22.7
