A geometrical framework for f –statistics
2020
AbstractA detailed derivation of the f–statistics formalism is made from a geometrical framework. It is shown that the f–statistics appear when a genetic distance matrix is constrained to describe a four population phylogenetic tree. The choice of genetic metric is crucial and plays an outstanding role as regards the tree–like–ness criterion. The case of lack of treeness is interpreted in the formalism as presence of population admixture. In this respect, four formulas are given to estimate the admixture proportions. One of them is the so–called f4–ratio estimate and we show that a second one is related to a known result developed in terms of the fixation index FST. An illustrative numerica…
Drivers of Competitiveness in European High-Tech Industries
2019
Our paper builds on the importance of high-tech manufacturing and knowledge-intensive services as significant competitiveness and economic growth drivers in the European Union and offers a fresh approach of the study on the competitiveness of secondary and tertiary high-tech industries across EU member states. Our analysis covers the 2008–2015 period and includes twelve old and new EU members. We opt for a balanced panel data approach in OLS and ARIMA frameworks to investigate the competitiveness of high-technology industries in the EU with the aim of uncovering the nature of the main explanatory factors behind their performance. Our results show that the number of persons employed and the …
Drivers of CO2 emissions in the former Soviet Union: A country level IPAT analysis from 1990 to 2010
2013
There are a small number of countries that have managed to decrease emissions over the last two decades e most of them emerged from the FSU (former Soviet Union ). CO2 emissions for these countries combined have decreased by 35% between 1990 and 2010, while global emissions increased by 44%. Most studies investigate the FSU as a single block ignoring the significant and persistent diversity among countries in the region. This study is the first providing detailed country by country analyses determining factors for changes in post-Soviet republics by applying a disaggregated version of the commonly used (IPAT) index decomposition analysis including energy intensity, affluence industrializati…
Decomposition analysis of bioresources: Implementing a competitive and sustainable bioeconomy strategy in the Baltic Sea Region
2021
Bioeconomy development has become one of the new trends in policy design and research. This study looks at biotic resource extraction in the Baltic Sea region countries providing detailed country by country analyses of factors affecting changes in resource extraction. The study is based on the index decomposition analysis including factors related to bioeconomy strategies such as the population, share of people employed in bioeconomy, labour intensity, biotic resource extraction productivity, share of bioeconomy, export intensity, and share of bioresource export. The main factors increasing biotic resource extraction were the growth in labour material intensity, biotic extraction productivi…
<title>Refractive properties of separate erythrocytes of Chernobyl clean-up workers at different pH</title>
2000
This study is focused on the modifications in erythrocytes of Chernobyl nuclear power plant accident clean-up workers as a late health effect of short-term impact of high level radioactive contamination. As a result, a new method based on erythrocyte (RBC) refractive index properties at different pH has been elaborated. According to the light dispersion theory for fluids refractive index is associated with molecules mass m. This feature is widely used for estimation of cell dry mass. But there is another refractive index dependency from molecules charge q regardless of its sing. This feature is not being used for cell quantitative and qualitative characterization. In this study, RBC were in…
2020
The objective of this study was to analyze the associations of various individual- and environmental-related factors with subgroups of daily, frequent, moderate and low moderate-to-vigorous physical activity (MVPA) among children and adolescents. Data were obtained from the Finnish School-age Physical Activity (FSPA) study 2016 from 4677 national representative 11-, 13-, and 15-year-old children and adolescents. MVPA and individual- and environmental-related factors were assessed by a questionnaire and analyzed by two-level logistic regression. Seventeen of the twenty-one variables were statistically significantly associated with MVPA. However, only three variables were statistically signif…
Genetic risk profiles for a childhood with severely overweight
2013
Summary What is already known about this subject Genome-wide association studies have identified susceptibility loci, conferring only small effects to obesity. We selected 12 from the most accepted susceptibility genes to overweight, which have been corroborated in different populations and series of thousands of adult individuals. Single-nucleotide polymorphisms variants can have a cumulative effect on common forms of obesity, to create a genetic risk score. What this study adds We concentrated on 109 single-nucleotide polymorphisms (SNPs) located in 12 loci previously reported in association to body mass index at genome-wide significant level, for individuals of European ancestry. To iden…
Assessing the Beneficial Effects of Economic Growth: The Harmonic Growth Index
2011
In this paper we introduce the multidimensional notion of harmonic growth as a situation of diffused well-being associated to an increase of per capita GDP. We say that a country experienced a harmonic growth if during the observed period all the key indicators, proxies of the endogenous and exogenous forces driving population well-being, show a significantly common pattern with the income dynamics. The notion is operationalized via an index of time series harmony which follows the functional data analysis approach. This Harmonic Growth Index (HGI) is based on comparisons between the coefficients from cubic B-splines interpolation. Such indices are then synthesized in order to provide the g…
Epidemiology of Mantle Cell Lymphoma: A Population-Based Study in France
2011
Abstract Abstract 5222 Introduction: Mantle cell lymphoma (MCL) is an aggressive and rare B-cell lymphoma entity representing around 5–8% of non-Hodgkin's lymphomas in adults. To our knowledge no data is available on the epidemiology of MCL in France. We aimed to describe incidence, survival and main clinical characteristics of MCL in a French population. Methods: Patients diagnosed with MCL were identified in three administrative areas covered by an haematological malignancies registry: the Côte d'Or (from 1988 to 2008), the Basse-Normandie (from 1997 to 2006) and the Gironde (from 2002 to 2006). Main clinical features and management characteristics were collected. World age-standardised …
