Determinants of Nonprofit Sector Density: A Stakeholder Approach Vrije Universiteit Brussel
Why do nonprofit organizations exist? From an economic perspective, a number of major theories have been proposed to explain their existence. However, when exploring determinants of nonprofit sector density, one needs to take into account that demand and supply factors operate simultaneously and that it is difficult to separate them. By using a stakeholder approach, we develop a more integrative framework for understanding variations in ...

Study of ergodic divertor edge density regimes on the tokamaks Tore Supra and TEXTOR, and sensitivity of tunnel probe electron temperature measurements to a suprathermal electron component Universiteit Gent
Controlled thermonuclear fusion offers one possible option to meet our future energy needs in a sustainable way. Magnetic confinement in a so-called 'tokamak'-machine is a possible approach towards the achievement of a burning plasma. An important issue in this tokamak research is the transition of the plasma edge to the inner wall. A first topic that is addressed in this thesis, is the ergodic divertor (ED) configuration. An ED achieves the ...
Named Entity Recognition in Biomedical Literature: A Comparison of Support Vector Machines and Conditional Random Fields Vrije Universiteit Brussel
In this paper, we propose two named entity recognition systems for biomedical literature, System1 using support vector machines and System2 using conditional random fields. Through employing several sets of experiments, we make a comprehensive comparison between these two systems. The final results reflect that System2 can achieve higher accuracy than System1, because System2 can catch more essential properties by handling the richer set of ...
Malaria transmission and vector behaviour in a forested malaria focus in central Vietnam and the implications for vector control Instituut voor Tropische Geneeskunde
BACKGROUND: In Vietnam, malaria is becoming progressively restricted to specific foci where human and vector characteristics alter the known malaria epidemiology, urging for alternative or adapted control strategies. Long-lasting insecticidal hammocks (LLIH) were designed and introduced in Ninh Thuan province, south-central Vietnam, to control malaria in the specific context of forest malaria. An entomological study in this specific forested ...
High serum FSH is not a risk factor for low bone mineral density in infertile men KU Leuven
BACKGROUND: Male infertility is associated with a higher long-term morbidity and mortality risk. However, it is not clear which diseases are contributing to this risk. Osteoporosis is a possible factor, as it is a frequent disease and sex steroids regulate both fertility and bone health. Furthermore, there are data indicating that high FSH levels in women are related to low bone mineral density (BMD), independent of estradiol levels. As ...
Momentum distrubution, x-ray scattering factor, and off-diagonal alectron density generated by a bare Coulomb potential in the nonrelativistic limit of a large number of closed shells Vrije Universiteit Brussel
In earlier work, one of us displayed an exact Thomas-Fermi (TF) method for kinetic energy and other averages of the Compton profile for atomic closed shells in a bare Coulomb field. Here, we are also interested in the semiclassical TF-like method but now in relation to the momentum density itself in the limit of a large number of closed shells. Exact off-diagonal density matrices are also given explicitly, for both configuration and momentum ...
