    Notes: This paper is intended to highlight the role of cost increases in the inflation process. In the course of the analysis a distinction is made between three different types of cost inflation: (i) exogenous cost impulses; (ii) competing income claims, both by way of bargaining in markets and by competition in the political arena; and (iii) attempts to preserve the purchasing power of income. Each category is discussed in some detail. The paper also discusses alternative methods of fighting cost inflation, including some issues pertaining to cost-accommodating demand management and incomes policy.

    Large recurrent microdeletions associated with schizophrenia (2008)

    Publication Date: 2008-08-01
    Description: Reduced fecundity, associated with severe mental disorders, places negative selection pressure on risk alleles and may explain, in part, why common variants have not been found that confer risk of disorders such as autism, schizophrenia and mental retardation. Thus, rare variants may account for a larger fraction of the overall genetic risk than previously assumed. In contrast to rare single nucleotide mutations, rare copy number variations (CNVs) can be detected using genome-wide single nucleotide polymorphism arrays. This has led to the identification of CNVs associated with mental retardation and autism. In a genome-wide search for CNVs associating with schizophrenia, we used a population-based sample to identify de novo CNVs by analysing 9,878 transmissions from parents to offspring. The 66 de novo CNVs identified were tested for association in a sample of 1,433 schizophrenia cases and 33,250 controls. Three deletions at 1q21.1, 15q11.2 and 15q13.3 showing nominal association with schizophrenia in the first sample (phase I) were followed up in a second sample of 3,285 cases and 7,951 controls (phase II). All three deletions significantly associate with schizophrenia and related psychoses in the combined sample. The identification of these rare, recurrent risk variants, having occurred independently in multiple founders and being subject to negative selection, is important in itself. CNV analysis may also point the way to the identification of additional and more prevalent risk variants in genes and pathways involved in schizophrenia.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2687075/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2687075/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stefansson, Hreinn -- Rujescu, Dan -- Cichon, Sven -- Pietilainen, Olli P H -- Ingason, Andres -- Steinberg, Stacy -- Fossdal, Ragnheidur -- Sigurdsson, Engilbert -- Sigmundsson, Thordur -- Buizer-Voskamp, Jacobine E -- Hansen, Thomas -- Jakobsen, Klaus D -- Muglia, Pierandrea -- Francks, Clyde -- Matthews, Paul M -- Gylfason, Arnaldur -- Halldorsson, Bjarni V -- Gudbjartsson, Daniel -- Thorgeirsson, Thorgeir E -- Sigurdsson, Asgeir -- Jonasdottir, Adalbjorg -- Jonasdottir, Aslaug -- Bjornsson, Asgeir -- Mattiasdottir, Sigurborg -- Blondal, Thorarinn -- Haraldsson, Magnus -- Magnusdottir, Brynja B -- Giegling, Ina -- Moller, Hans-Jurgen -- Hartmann, Annette -- Shianna, Kevin V -- Ge, Dongliang -- Need, Anna C -- Crombie, Caroline -- Fraser, Gillian -- Walker, Nicholas -- Lonnqvist, Jouko -- Suvisaari, Jaana -- Tuulio-Henriksson, Annamarie -- Paunio, Tiina -- Toulopoulou, Timi -- Bramon, Elvira -- Di Forti, Marta -- Murray, Robin -- Ruggeri, Mirella -- Vassos, Evangelos -- Tosato, Sarah -- Walshe, Muriel -- Li, Tao -- Vasilescu, Catalina -- Muhleisen, Thomas W -- Wang, August G -- Ullum, Henrik -- Djurovic, Srdjan -- Melle, Ingrid -- Olesen, Jes -- Kiemeney, Lambertus A -- Franke, Barbara -- GROUP -- Sabatti, Chiara -- Freimer, Nelson B -- Gulcher, Jeffrey R -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Andreassen, Ole A -- Ophoff, Roel A -- Georgi, Alexander -- Rietschel, Marcella -- Werge, Thomas -- Petursson, Hannes -- Goldstein, David B -- Nothen, Markus M -- Peltonen, Leena -- Collier, David A -- St Clair, David -- Stefansson, Kari -- 089061/Wellcome Trust/United Kingdom -- G0901310/Medical Research Council/United Kingdom -- PDA/02/06/016/Department of Health/United Kingdom -- R01 MH078075/MH/NIMH NIH HHS/ -- R01MH71425-01A1/MH/NIMH NIH HHS/ -- England -- Nature. 2008 Sep 11;455(7210):232-6. doi: 10.1038/nature07229.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNS Division, deCODE genetics, Sturlugata 8, IS-101 Reykjavik, Iceland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18668039" target="_blank"〉PubMed〈/a〉

    Parental origin of sequence variants associated with complex diseases (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-18
    Description: Effects of susceptibility variants may depend on from which parent they are inherited. Although many associations between sequence variants and human traits have been discovered through genome-wide associations, the impact of parental origin has largely been ignored. Here we show that for 38,167 Icelanders genotyped using single nucleotide polymorphism (SNP) chips, the parental origin of most alleles can be determined. For this we used a combination of genealogy and long-range phasing. We then focused on SNPs that associate with diseases and are within 500 kilobases of known imprinted genes. Seven independent SNP associations were examined. Five-one with breast cancer, one with basal-cell carcinoma and three with type 2 diabetes-have parental-origin-specific associations. These variants are located in two genomic regions, 11p15 and 7q32, each harbouring a cluster of imprinted genes. Furthermore, we observed a novel association between the SNP rs2334499 at 11p15 and type 2 diabetes. Here the allele that confers risk when paternally inherited is protective when maternally transmitted. We identified a differentially methylated CTCF-binding site at 11p15 and demonstrated correlation of rs2334499 with decreased methylation of that site.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3746295/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3746295/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kong, Augustine -- Steinthorsdottir, Valgerdur -- Masson, Gisli -- Thorleifsson, Gudmar -- Sulem, Patrick -- Besenbacher, Soren -- Jonasdottir, Aslaug -- Sigurdsson, Asgeir -- Kristinsson, Kari Th -- Jonasdottir, Adalbjorg -- Frigge, Michael L -- Gylfason, Arnaldur -- Olason, Pall I -- Gudjonsson, Sigurjon A -- Sverrisson, Sverrir -- Stacey, Simon N -- Sigurgeirsson, Bardur -- Benediktsdottir, Kristrun R -- Sigurdsson, Helgi -- Jonsson, Thorvaldur -- Benediktsson, Rafn -- Olafsson, Jon H -- Johannsson, Oskar Th -- Hreidarsson, Astradur B -- Sigurdsson, Gunnar -- DIAGRAM Consortium -- Ferguson-Smith, Anne C -- Gudbjartsson, Daniel F -- Thorsteinsdottir, Unnur -- Stefansson, Kari -- 077016/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- G9723500/Medical Research Council/United Kingdom -- K08 AR055688/AR/NIAMS NIH HHS/ -- MC_U106179471/Medical Research Council/United Kingdom -- MC_U106179474/Medical Research Council/United Kingdom -- MC_U127592696/Medical Research Council/United Kingdom -- R01 DK029867/DK/NIDDK NIH HHS/ -- England -- Nature. 2009 Dec 17;462(7275):868-74. doi: 10.1038/nature08625.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉deCODE genetics, Sturlugata 8, 101 Reykjavik, Iceland. kong@decode.is〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20016592" target="_blank"〉PubMed〈/a〉

    Fine-scale recombination rate differences between sexes, populations and individuals (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-29
    Description: Meiotic recombinations contribute to genetic diversity by yielding new combinations of alleles. Recently, high-resolution recombination maps were inferred from high-density single-nucleotide polymorphism (SNP) data using linkage disequilibrium (LD) patterns that capture historical recombination events. The use of these maps has been demonstrated by the identification of recombination hotspots and associated motifs, and the discovery that the PRDM9 gene affects the proportion of recombinations occurring at hotspots. However, these maps provide no information about individual or sex differences. Moreover, locus-specific demographic factors like natural selection can bias LD-based estimates of recombination rate. Existing genetic maps based on family data avoid these shortcomings, but their resolution is limited by relatively few meioses and a low density of markers. Here we used genome-wide SNP data from 15,257 parent-offspring pairs to construct the first recombination maps based on directly observed recombinations with a resolution that is effective down to 10 kilobases (kb). Comparing male and female maps reveals that about 15% of hotspots in one sex are specific to that sex. Although male recombinations result in more shuffling of exons within genes, female recombinations generate more new combinations of nearby genes. We discover novel associations between recombination characteristics of individuals and variants in the PRDM9 gene and we identify new recombination hotspots. Comparisons of our maps with two LD-based maps inferred from data of HapMap populations of Utah residents with ancestry from northern and western Europe (CEU) and Yoruba in Ibadan, Nigeria (YRI) reveal population differences previously masked by noise and map differences at regions previously described as targets of natural selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kong, Augustine -- Thorleifsson, Gudmar -- Gudbjartsson, Daniel F -- Masson, Gisli -- Sigurdsson, Asgeir -- Jonasdottir, Aslaug -- Walters, G Bragi -- Jonasdottir, Adalbjorg -- Gylfason, Arnaldur -- Kristinsson, Kari Th -- Gudjonsson, Sigurjon A -- Frigge, Michael L -- Helgason, Agnar -- Thorsteinsdottir, Unnur -- Stefansson, Kari -- England -- Nature. 2010 Oct 28;467(7319):1099-103. doi: 10.1038/nature09525.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉deCODE genetics, Sturlugata 8, 101 Reykjavik, Iceland. kong@decode.is〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20981099" target="_blank"〉PubMed〈/a〉

    Effects of axisymmetric strain on a passive scalar field: modelling and experiment (2009)
    Cambridge University Press
    Details
    Publication Date: 2009-06-01
    Description: Homogeneous, approximately isotropic turbulence at two Taylor-scale Reynolds numbers, Rλ = 50, 190, with a mean transverse temperature gradient is passed through an axisymmetric contraction. The effects of the straining on the velocity field, and on the passive scalar field, are investigated within the contraction as are the effects of releasing the strain in the post-contraction region. Components of the fluctuating velocity and scalar gradient covariance are measured in order to understand their relation to the large-scale anisotropy of the flow. The scale-dependent spectral evolution of the scalar is also determined. A tensor model is constructed to predict the evolution of the fluctuating scalar gradient covariance. The model constants are determined in the post-contraction relaxation region, where the flow geometry does not vary. The model is shown to perform well throughout the flow, even in the contraction in which the geometry varies. Rapid distortion theory is applied to the scalar field in the contraction, and its solutions are compared to the experimental results. © 2009 Cambridge University Press.

    Intermittency, pressure and acceleration statistics from hot-wire measurements in wind-tunnel turbulence (2004)
    Cambridge University Press
    Details
    Publication Date: 2004-02-25
    Description: From hot-wire anemometer measurements in active-grid wind-tunnel turbulence we have determined the Reynolds number dependence of the velocity derivative moments, the mean-squared pressure gradient, X, and the normalized acceleration variance, a0, over the Reynolds number range 100 ≤ Ri ≤ 900. The values of X and a0 were obtained from the fourth-order velocity structure functions. The derivative moments show power-law dependence on Reynolds number and the exponent is the same with or without shear. In particular, we find the derivative kurtosis, K∂u/∂ ∼ R〈sub/〉0.39 and there is no evidence of the transition that has been observed in this quantity in some recent work. We find that at high Reynolds numbers, χ and a0 tend to values similar to those obtained by direct particle tracking measurements and by direct numerical simulation. However, at lower Reynolds number our estimates of χ and a0 appear to be affected by the evaluation technique which imposes strict requirements on local homogeneity and isotropy. © 2004 Cambridge University Press.

    Inertial particle acceleration in strained turbulence (2015)
    Cambridge University Press
    Details
    Publication Date: 2015-11-12
    Description: The dynamics of inertial particles in turbulence is modelled and investigated by means of direct numerical simulation of an axisymmetrically expanding homogeneous turbulent strained flow. This flow can mimic the dynamics of particles close to stagnation points. The influence of mean straining flow is explored by varying the dimensionless strain rate parameter $Sk_{0}/{itepsilon}_{0}$ from 0.2 to 20, where $S$ is the mean strain rate, $k_{0}$ and ${itepsilon}_{0}$ are the turbulent kinetic energy and energy dissipation rate at the onset of straining. We report results relative to the acceleration variances and probability density functions for both passive and inertial particles. A high mean strain is found to have a significant effect on the acceleration variance both directly by an increase in the frequency of the turbulence and indirectly through the coupling of the fluctuating velocity and the mean flow field. The influence of the strain on the normalized particle acceleration probability distribution functions is more subtle. For the case of a passive particle we can approximate the acceleration variance with the aid of rapid-distortion theory and obtain good agreement with simulation data. For the case of inertial particles we can write a formal expression for the accelerations. The magnitude changes in the inertial particle acceleration variance and the effect on the probability density function are then discussed in a wider context for comparable flows, where the effects of the mean flow geometry and of the anisotropy at small scales are present.

    Law of the wall in an unstably stratified turbulent channel flow (2015)
    Cambridge University Press
    Details
    Publication Date: 2015-09-17
    Description: We perform direct numerical simulations of an unstably stratified turbulent channel flow to address the effects of buoyancy on the boundary layer dynamics and mean field quantities. We systematically span a range of parameters in the space of friction Reynolds number (Reτ)and Rayleigh number (Ra). Our focus is on deviations from the logarithmic law of the wall due to buoyant motion. The effects of convection in the relevant ranges are discussed, providing measurements of mean profiles of velocity, temperature and Reynolds stresses as well as of the friction coefficient. A phenomenological model is proposed and shown to capture the observed deviations of the velocity profile in the log-law region from the non-convective case. © 2015 Cambridge University Press.
