    National technology policies and international friction: Theory, evidence, and policy options

    Get PDF
    Economic theory and empirical evidence suggest that governments might usefully intervene in high-technology competition in two ways: First, they could act as a neutral agent that creates the necessary credibility, commitment and mutual trust among private companies so as to facilitate cooperation in high-risk, high-volume R&D. Second, if — in view of the externalities involved — an element of subsidization is to be added, this could be done in a nondiscriminatory fashion. A favourable tax treatment of R&D expenditures may be the most appropriate tool to achieve this task. In practice, governments do engage in targeted industrial and technology policies, whether justified on economic grounds or not. As a consequence, the string of trade conflicts in hightech industries that began in the 1980s is unlikely to end in the near future, unless substantial reforms are undertaken in some crucial areas of the international trade order. Above all, appropriate reform steps should be made with a view to the regulations on (i) subsidies, (ii) structural impediments, and (iii) dumping and anti-dumping. To mitigate the frictions that arise from a subsidization of domestic firms, a new set of rules should be established. The rules should provide that all plans to grant or to alter existing subsidies are to be notified to and approved by the WTO. Moreover, all subsidies should be ranked according to their potential distortional effects on competition and trade. For each category, quantitative limits that constrain the provision of subsidies to a certain fraction of the subsidy base should be set. To facilitate further liberalization steps, a country should be allowed to exceed these limits, if a national subsidy program offers an open access to firms located in third markets. Besides restrictive business practices of private firms, government regulations and technical standards are the most important structural impediments to trade. Existing GATT Articles already offer a multilateral route to conflict resolution in cases of structural impediments. However, this route has not been used by complainants up to now. The so-called "non-violation" clause of Article 23 GATT provides access to a multilateral dispute settlement even if the defending country has not explicitly violated GATT rules. This route should be tested and, if necessary, improved. To reduce the potential for a protectionist abuse of existing anti-dumping regulations, explicit reference to the state of competition in the relevant exporting and importing country markets should be made in anti-dumping investigations. To meet specific anti-trust concerns in hightech competition — notably with respect to network externalities, systems leverage, standardization, and innovation cartels — one might consider adopting the Draft International Antitrust Code (DIAC) that has recently been proposed by an international group of legal experts. --

    Calibration of PMP Condensation Particle Number Counters - Effect of Material on Linearity and Counting Efficiency

    Get PDF
    Recently the particle number method was proposed to the light duty regulation, so the proper calibration of Particle Number Counters (PNCs) will be very important. Calibration includes the linearity measurement and the counting efficiency measurement. Labs will have to demonstrate compliance of their PNCs with a traceable standard within a 12 month period prior to the emissions test. Compliance can be demonstrated by: -Primary method: By comparison of the response of the PNC under calibration with that of a calibrated aerosol electrometer when simultaneously sampling electrostatically classified calibration particles, or -Secondary method: By comparison of the response of the PNC under calibration with that of a second PNC which has been directly calibrated by the above method. Compliance testing includes linearity and detection efficiency with particles of 23 nm electrical mobility diameter. A check of the counting efficiency with 41 nm particles is not required. A workshop was organised to investigate the effect of the material on the calibration procedures and the uncertainties of the suggested procedure. GRIMM and TSI provided PNCs and AEA, MATTER, GRIMM, TSI provided five particle generators. The experiments were conducted in the European¿s Commissions laboratories (JRC). Heavy duty diesel engine (w/o aftertreatment) particles were also produced (measurements downstream a thermodenuder) at idle and a medium load mode. The measured data were evaluated by JRC. The results showed that there was an effect of the material used and suggestions were given. In addition the uncertainties of the procedure were quantified. Theoretical calculations showed the corrections that should be applied.JRC.H.4-Transport and air qualit

    An Analysis of Two Genome-wide Association Meta-analyses Identifies a New Locus for Broad Depression Phenotype

    AbstractBackgroundThe genetics of depression has been explored in genome-wide association studies that focused on either major depressive disorder or depressive symptoms with mostly negative findings. A broad depression phenotype including both phenotypes has not been tested previously using a genome-wide association approach. We aimed to identify genetic polymorphisms significantly associated with a broad phenotype from depressive symptoms to major depressive disorder.MethodsWe analyzed two prior studies of 70,017 participants of European ancestry from general and clinical populations in the discovery stage. We performed a replication meta-analysis of 28,328 participants. Single nucleotide polymorphism (SNP)-based heritability and genetic correlations were calculated using linkage disequilibrium score regression. Discovery and replication analyses were performed using a p-value-based meta-analysis. Lifetime major depressive disorder and depressive symptom scores were used as the outcome measures.ResultsThe SNP-based heritability of major depressive disorder was 0.21 (SE = 0.02), the SNP-based heritability of depressive symptoms was 0.04 (SE = 0.01), and their genetic correlation was 1.001 (SE = 0.2). We found one genome-wide significant locus related to the broad depression phenotype (rs9825823, chromosome 3: 61,082,153, p = 8.2 × 10–9) located in an intron of the FHIT gene. We replicated this SNP in independent samples (p = .02) and the overall meta-analysis of the discovery and replication cohorts (1.0 × 10–9).ConclusionsThis large study identified a new locus for depression. Our results support a continuum between depressive symptoms and major depressive disorder. A phenotypically more inclusive approach may help to achieve the large sample sizes needed to detect susceptibility loci for depression

    Genome-wide interaction study of a proxy for stress-sensitivity and its prediction of major depressive disorder

    Individual response to stress is correlated with neuroticism and is an important predictor of both neuroticism and the onset of major depressive disorder (MDD). Identification of the genetics underpinning individual differences in response to negative events (stress-sensitivity) may improve our understanding of the molecular pathways involved, and its association with stress-related illnesses. We sought to generate a proxy for stress-sensitivity through modelling the interaction between SNP allele and MDD status on neuroticism score in order to identify genetic variants that contribute to the higher neuroticism seen in individuals with a lifetime diagnosis of depression compared to unaffected individuals. Meta-analysis of genome-wide interaction studies (GWIS) in UK Biobank (N = 23,092) and Generation Scotland: Scottish Family Health Study (N = 7,155) identified no genome-wide significance SNP interactions. However, gene-based tests identified a genome-wide significant gene, ZNF366, a negative regulator of glucocorticoid receptor function implicated in alcohol dependence (p = 1.48x10-7; Bonferroni-corrected significance threshold p < 2.79x10-6). Using summary statistics from the stress-sensitivity term of the GWIS, SNP heritability for stress-sensitivity was estimated at 5.0%. In models fitting polygenic risk scores of both MDD and neuroticism derived from independent GWAS, we show that polygenic risk scores derived from the UK Biobank stress-sensitivity GWIS significantly improved the prediction of MDD in Generation Scotland. This study may improve interpretation of larger genome-wide association studies of MDD and other stress-related illnesses, and the understanding of the etiological mechanisms underpinning stress-sensitivity

    Hair Cortisol in Twins : Heritability and Genetic Overlap with Psychological Variables and Stress-System Genes

    A. Palotie on työryhmän jäsen.Hair cortisol concentration (HCC) is a promising measure of long-term hypothalamus-pituitary-adrenal (HPA) axis activity. Previous research has suggested an association between HCC and psychological variables, and initial studies of inter-individual variance in HCC have implicated genetic factors. However, whether HCC and psychological variables share genetic risk factors remains unclear. The aims of the present twin study were to: (i) assess the heritability of HCC; (ii) estimate the phenotypic and genetic correlation between HPA axis activity and the psychological variables perceived stress, depressive symptoms, and neuroticism; using formal genetic twin models and molecular genetic methods, i.e. polygenic risk scores (PRS). HCC was measured in 671 adolescents and young adults. These included 115 monozygotic and 183 dizygotic twin-pairs. For 432 subjects PRS scores for plasma cortisol, major depression, and neuroticism were calculated using data from large genome wide association studies. The twin model revealed a heritability for HCC of 72%. No significant phenotypic or genetic correlation was found between HCC and the three psychological variables of interest. PRS did not explain variance in HCC. The present data suggest that HCC is highly heritable. However, the data do not support a strong biological link between HCC and any of the investigated psychological variables.Peer reviewe

    Identification of common genetic risk variants for autism spectrum disorder

    Autism spectrum disorder (ASD) is a highly heritable and heterogeneous group of neurodevelopmental phenotypes diagnosed in more than 1% of children. Common genetic variants contribute substantially to ASD susceptibility, but to date no individual variants have been robustly associated with ASD. With a marked sample-size increase from a unique Danish population resource, we report a genome-wide association meta-analysis of 18,381 individuals with ASD and 27,969 controls that identified five genome-wide-significant loci. Leveraging GWAS results from three phenotypes with significantly overlapping genetic architectures (schizophrenia, major depression, and educational attainment), we identified seven additional loci shared with other traits at equally strict significance levels. Dissecting the polygenic architecture, we found both quantitative and qualitative polygenic heterogeneity across ASD subtypes. These results highlight biological insights, particularly relating to neuronal function and corticogenesis, and establish that GWAS performed at scale will be much more productive in the near term in ASD
