Análisis del proceso de implementación de la política pública de juventud desde el enfoque top-down en el municipio de El Carmen de Viboral (2015-2019)
(Universidad EAFITMaestría en Gobierno y Políticas PúblicasEscuela de HumanidadesMedellín, 2021)
This research seeks to analyze the Public Policy for Youth implementation at El Carmen de Viboral (2015-2019) under a top-down design approach. To this effect, the main antecedents of the mentioned instrument are presented; ...
Physical stress modifies top-down and bottom-up forcing on plant growth and reproduction in a coastal ecosystem
(Ecological Society of America, 2015-08)
Bottom-up and top-down effects act together to exert strong control over plant growth and reproduction, but how physical stress modifies those interactive forces remains unclear. Even though empirical evidence is scarce, ...
Is top-down control by predators driving insect abundance and herbivory rates in fragmented forests?
(2012)
The effects of forest fragmentation on ecological interactions and particularly on food webs have scarcely been analysed. There is usually less herbivory in forest fragments than in continuous forests. Here we hypothesize ...
The semantic congruency effect into bistable visual perception: a study based on tones of voice as top-down modulating stimuli
Background: Bistable images (or ambiguous images) have the chance to be interpreted in two
different ways. Owing to its physical features, this type of images offers two independentvisual
perceptswhich are associated ...
Top-down and bottom-up regulation of planktonic communities in a warm temperate wetland
(Oxford University Press, 2010-02)
This field experimental study simultaneously analysed the effects of predation (top-down) and nutrients (bottom-up) on planktonic communities (phytoplankton, zooplankton, heterotrophic nanoflagellates and ciliates) in a ...
Knowledge inflows effects on middle managers' ambidexterity and performance
(Emerald Group, 2015)
Purpose - The purpose of this paper is to report on lab experiments conducted to determine what impact managerial top-down knowledge transfer has on a middle manager's individual ambidexterity and decision performance. ...
Bottom-up and top-down effects of browning and warming on shallow lake food webs
(Wiley Blackwell Publishing, Inc, 2019-03)
Productivity and trophic structure of aquatic ecosystems result from a complex interplay of19 bottom-up and top-down forces that operate across benthic and pelagic food web compartments.20 Projected global changes urge the ...
Cascading top-down effects on estuarine intertidal meiofaunal and algal assemblages
(Elsevier Science, 2013-06)
Interactions between organisms are important determinants of species distributions and abundances. Due to the high complexity of interactions between species in natural systems, the outcome of a given interaction can affect ...
Mammal defaunation as surrogate of trophic cascades in a biodiversity hotspot
(2013-07-01)
Preserving large tracts of natural habitats is essential to maintain biodiversity. Nevertheless, even large areas may still suffer from less visible impacts such as loss of ecological processes. Because mapping ecological ...
