Information flow top-down and bottom-up in leadership. In the fields of management and organization, the terms "top-down" and "bottom-up" are used to describe how decisions are made and/or how change is implemented. [17] A "top-down" approach is where an executive decision maker or other top person makes the decisions of how something should be ...
Bottom-up versus top-down [ edit ] The bottom-up name comes from the concept of a parse tree , in which the most detailed parts are at the bottom of the upside-down tree, and larger structures composed from them are in successively higher layers, until at the top or "root" of the tree a single unit describes the entire input stream.
Top-down and bottom-up design of information ordering; Top-down parsing, a parsing strategy beginning at the highest level of the parse tree Top-down parsing language, an analytic formal grammar to study top-down parsers; Top-down perspective, a camera angle in computer and video games; Top-down shooter, a subgenre of video games
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
Top-down vs bottom-up proteomics. Top-down proteomics is a method of protein identification that either uses an ion trapping mass spectrometer to store an isolated protein ion for mass measurement and tandem mass spectrometry (MS/MS) analysis [1] [2] or other protein purification methods such as two-dimensional gel electrophoresis in conjunction with MS/MS. [3] Top-down proteomics is capable ...
"They use a tumbling action, causing clothes to move in an up-and-down circular motion," says Galinsky. "This tumbling effect creates less stress on clothing and reduces friction between items."
Top-down processing is typically designed by outsiders who can only perceive a community's need and so community needs are often only marginally addressed or not addressed at all. By contrast, bottom-up processing is defined as "observing or monitoring efforts defined and undertaken at the local scale and brought forward to higher-level bodies ...
When the top looks dry but the soil below is moist—hold back on watering. Some plants, like hibiscus, need frequent watering, while others, like salvia, are fine with less frequent watering.
