Direct and indirect effects of screening for chlamydia trachomatis on the prevention of pelvic inflammatory disease University of Antwerp
Background: Pelvic inflammatory disease (PID) results from the ascending spread of microorganisms, including Chlamydia trachomatis, to the upper genital tract. Screening could improve outcomes by identifying and treating chlamydial infections before they progress to PID (direct effect) or by reducing chlamydia transmission (indirect effect). Methods: We developed a compartmental model that represents a hypothetical heterosexual population and ...
Direct and indirect effects of metal stress on physiology and life history variation in field populations of a lycosid spider Ghent University University of Antwerp
Larger direct than indirect effects of multiple environmental changes on leaf nitrogen of forest herbs Ghent University
Aims: Disentangling direct and indirect effects of global change drivers on plant nitrogen (N) uptake in leaves is important for understanding species and community responses in a changing world. Methods: We created understorey herb communities on forest soils with and without recent agricultural history. We traced pulse additions of (NH4NO3)-N-15-N-15 within these mesocosms while applying two-level factorial treatments of N enrichment, warming ...
Direct and understorey-mediated indirect effects of human-induced environmental changes on litter decomposition in temperate forest Ghent University
Human-induced environmental changes in temperature, light availability due to forest canopy management, nitrogen deposition, and land-use legacies can alter ecosystem processes such as litter decomposition. These influences can be both direct and indirect via altering the performance of understorey vegetation. To identify the direct and indirect effects of environmental changes on litter decomposition, we performed an experiment with ...
The indirect effects of foreign direct investment on trade: A network perspective KU Leuven
The relationship between international trade and foreign direct investment (FDI) is one of the main features of globalisation. In this paper, we investigate the effects of FDI on trade from a network perspective, since FDI takes not only direct but also indirect channels from origin to destination countries because of firms’ incentive to reduce tax burden, to minimise coordination costs and to break barriers to market entry. We use a unique data ...
Field-scale assessment of direct and indirect effects of soil texture on organic matter mineralization during a dry summer Ghent University
Soil texture plays a crucial role in organic matter (OM) mineralization through both direct interactions with minerals and indirect effects on soil moisture. Separating these effects could enhance the modelling of soil organic carbon (SOC) dynamics under climate change scenarios. However, the attempts have been limited smallscale experiments. Here, we studied the effects of soil texture on added OM mineralization in loamy sand, loam and silt ...
Survival in the understorey: Testing direct and indirect effects of microclimatological changes on Ixodes ricinus Hasselt University University of Antwerp Institute of Tropical Medicine
The distribution of ticks in the Ixodes ricinus species complex is partly driven by climate, with temperature and relative humidity affecting survival. These variables are driven by macroclimate, but vary locally due to microclimate buffering. This buffering has been suggested to be one of the driving forces behind variation in tick survival and density in time and space. In order to understand the role of the herb layer with respect to this ...
Development of the growth mindset scale : evidence of structural validity, measurement model, direct and indirect effects in Chinese samples Ghent University
To improve the efficiency of learning and promote achievements, the current paper explores the correlation of the growth mindset to students and teachers. This study aims to develop the growth mindset scale with the evidence of structural validity, measurement of direct and indirect effects in Chinese samples. To achieve the research objective, this study investigates 654 participants, including 321 students at different learning stages and 266 ...
