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…
Measuring the potential for growth in populations investing in diapause
2014
AbstractThe intrinsic rate of population increase (r) is a common performance measure in many ecological and evolutionary studies. However, in life cycles with diapause investment resources are split into a short-term (current population growth) and a long-term (population survival through periods of unsuitable habitat conditions) component, which complicates the use of r as a single performance measure. Here we propose a new measure that integrates both performance components into a single parameter, the potential intrinsic growth rate, rpot. This is the rate of increase that a population/genotype would have if no investment in diapausing stages would occur. We show that rpot can be comput…
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…
A Cross-sectional Growth Study of Forearm Length and Tibial Length in an Indigenous Andean Population of 6 to 19 Years of Age.
1997
Patterns of growth in forearm length and tibial length were studied in 149 school-children of Aymara ancestry (73 boys and 76 girls), aged 6 to 19 years. The investigation was based on a cross-sectional survey performed in 1987 in the rural community of Putre (3, 530 m), northern Chile. The results show that there is little sexual dimorphism over the age period of 6 to 13 years, while sex differences are more pronounced between the ages of 14 and 17 years, both for forearm length and tibial length, with boys having higher means. Correspondingly, the maximum values achieved for both measurements are greater in boys than in girls. The growth spurt begins about two years earlier in girls than …

Summary Background Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development. To date, internationally available estimates of population and fertility, although useful, have not been produced with transparent and replicable methods and do not use standardised estimates of mortality. We present single-calendar year and single-year of age estimates of fertility and population by sex with standardised and replicable methods. Methods We estimated population in 195 locations by single year of age and single calendar year from 1950 to 2017 with standardised and replicable methods. We based t…
Infanticide and Population Growth in the Bank Vole (Myodes glareolus): The Effect of Male Turnover and Density
2011
One major intrinsic factor affecting recruitment of young into a population is infanticide, the killing of conspecific young by adult males. It occurs in most mammal species, like our study species the bank vole (Myodes glareolus), and is widely accepted as an adaptive behavior, which may increase male fitness via nutritional gain, decreased competition, or an increased access to mates. A turnover of males in a population increases the risk of infanticide owing to a disruption of social structures. In a controlled field study, we tested the effects of total male turnover and density on juvenile recruitment and female space use in experimental bank vole populations. Juvenile recruitment decl…
How to address the mental health of migrant and refugee population in Europe? An integrated shift in health and social care services - MigHealthCare …
2020
Introduction Health and social care services across Europe are facing diverse challenges meeting the specific needs of migrants and refugees [1]. In this regard, vulnerable migrants fall outside mental healthcare services [2]. Based on this, Mig-Healthcare project, funded by the European Commission, explores the health needs of the migrant population in an effort to strengthen EU community-based services. Methods A total of 20 focus groups and 19 individual interviews were conducted between November 2017 and April 2018 with different stakeholders involved in the provision of health and social care to the migrant population in the 10 countries (Greece, France, Malta, Germany, Austria, Italy,…
Reliable computation and local mesh adaptivity in limit analysis
2019
The contribution is devoted to computations of the limit load for a perfectly plastic model with the von Mises yield criterion. The limit factor of a prescribed load is defined by a specific variational problem, the so-called limit analysis problem. This problem is solved in terms of deformation fields by a penalization, the finite element and the semismooth Newton methods. From the numerical solution, we derive a guaranteed upper bound of the limit factor. To achieve more accurate results, a local mesh adaptivity is used. peerReviewed
Education for optimized Life Cycle Management : The Project e-CIRP and its insights into embedding circular economy aspects to product design via tea…
2022
Publisher Copyright: © The Authors, published by EDP Sciences. The integration of circular economy-based life cycle management (LCM) into product design and optimisation is essential for the transformation towards a circular economy (CE). However, companies often lack the expertise to adapt life-cycle design (LCD) thinking in their business operations and are in need of respective capacity building. To close this apparent gap is the aim of the project e-CirP (Embedding Circular Economy into Product Design and Optimization) where LUT University, Fraunhofer, Technical University of Denmark, University of Padova, Delft University of Technology, University of Helsinki and Metso Outotec have wor…
