1990
The aim of the present article is to provide a statistical assessmentof the amount of public money developing countries will nedd to spend in order to meet the estimated demand for primary education in the year 2000 and to evaluate the cost of providing universal primary education by that date.

Earnings management to exceed thresholds in continental and Anglo-Saxon accounting models: The British and French cases
2017
International audience; The purpose of this paper is to compare the extent to which French and British firms manage their earnings in order to avoid losses, decreases in earnings and earnings below the forecasts of analysts. Further, this study aims to investigate the factors that potentially influence earnings management to exceed thresholds with reference to the Anglo-Saxon and continental accounting models. Britain and France, correspondingly, belong to those different socio-economic environments. Based on a panel data of 1771 French and 2057 British firm-year observations during the period 2002–2012, we show that all firms considered manage earnings to beat zero and last year’s earnings…
Hunger and sustainability
2019
This paper examines the problem of world hunger and discusses potential solutions to it. It reflects on the debate about whether transgenic foods should be used, which is more of a social controversy than a scientific one. Sustainability is considered a key driver for innovation that can be used as a basis for assessing the problem of hunger in the world, and the question is inseparable from its ethical aspects. Given that economic growth does not directly equate to human development, this paper states that it is necessary to address the problem of poverty and hunger from the capacity development framework according to human rights. Poverty causes disability by limiting human development; i…
Development of accelerometer-based light to vigorous physical activity in fitness profiles of school-aged children.
2021
This study examined the developmental trajectories of light (LPA) and moderate-to-vigorous physical activity (MVPA) in fitness profiles derived from motor competence, perceived motor competence, health-related fitness, and MVPA behaviour. Locomotor, stability, and object-control skills, muscular and cardiovascular fitness, and physical activity were assessed in 510 (girls 285, boys 225) Finnish school-aged children (Mage = 11.26 ± .33 years) over three years. Physical activity was measured using hip-mounted accelerometers. Fitness profiles were identified using latent profile analysis and the development of physical activity levels across four assessments was analysed with latent growth cur…
The Low Dimensionality of Development
2020
AbstractThe World Bank routinely publishes over 1500 “World Development Indicators” to track the socioeconomic development at the country level. A range of indices has been proposed to interpret this information. For instance, the “Human Development Index” was designed to specifically capture development in terms of life expectancy, education, and standard of living. However, the general question which independent dimensions are essential to capture all aspects of development still remains open. Using a nonlinear dimensionality reduction approach we aim to extract the core dimensions of development in a highly efficient way. We find that more than 90% of variance in the WDIs can be represen…
Effects of air pollution on dementia over Europe for present and future climate change scenarios.
2020
The scientific literature is scarce when referring to the influence of atmospheric pollutants on neurodegenerative diseases for present and future climate change scenarios. In this sense, this contribution evaluates the incidence of dementia (Alzheimer's disease, AD, and dementia from unspecified cause, DU) occurring in Europe associated with the exposure to air pollution (essentially NO2 and PM2.5) for the present climatic period (1991-2010) and for a future climate change scenario (RCP8.5, 2031-2050). The GEMM methodology has been applied to air pollution simulations using the chemistry/climate regional model WRF-Chem. Present population data were obtained from NASA's Center for Socioecon…
Environmental noise and population dynamics of the ciliated protozoa Tetrahymena thermophila in aquatic microcosms
2003
Population theory predicts that the reddened environmental noise, especially in combination with high population growth rate, reddens population dynamics, increases population variability and strengthens environment–population correlation. We tested these predictions with axenic populations of ciliated protozoa Tetrahymena thermophila. Populations with low and high growth rate were cultured in a stable environment, and in environments with sublethal temperature fluctuations that had blue, white and red spectra (i.e. negatively autocorrelated, uncorrelated, or positively autocorrelated, respectively). Population size and biomass of individuals were determined at 3-h intervals for 18 days. Dy…
Delayed mixis in rotifers: an adaptive response to the effects of density-dependent sex on population growth
2004
In most cyclically parthenogenetic life cycles, sex is needed to produce resting stages. In several species of cyclically parthenogenetic rotifers, some generations of clones are not responsive to a density-dependent signal that triggers sexual female production. These unresponsive rotifers hatch from resting eggs and typically pass 8–12 generations of female parthenogenesis before becoming receptive to the mixis signal. We addressed the selection for mixis delay using a simulation model. A delay of sexual reproduction could increase population growth through parthenogenesis and thus the number of resting eggs ultimately produced. In a monomorphic population without mixis delay, we determin…
Migration Flows in Finland: Regional Differences in Migration Determinants and Migrant Types
2003
The present study analyzes interregional migration flows in Finland during 1985-96 using a large sample from the longitudinal census data file. The regional concentration of population has sped up in recent years, and most migrants now head to five urban growth centers. The empirical analysis reveals that it is particularly the human capital component (young, educated individuals) that moves to, and stays in, the growth centers. They are attracted by the higher expected wages and employment chances. Conversely, some individuals, mainly older and less educated ones, move back to their original home regions. This countermovement reduces the speed of population concentration. Declining region…
