Indicator (genus)
''Indicator'' is a genus of near passerine birds in the honeyguide family. The name refers to the behaviour of some species, notably the greater honeyguide, which guide humans to bee colonies so that they can share in the spoils of wax and insects when the nest is broken into. ''Indicator'' honeyguides are brood parasites which lay eggs in a nest of another species, in a series of about five during five to seven days. Most favour hole-nesting species, often the related barbets and woodpecker Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks, and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. ...s. Nestlings have been known to physically eject their host's chicks from the nest, and they have hooks on their beaks with which they puncture the hosts' eggs or kill the nestlings, by repeated lacerations if not a fatal stab.

Environmental Indicator
Environmental indicators are simple measures that tell us what is happening in the environment. Since the environment is very complex, indicators provide a more practical and economical way to track the state of the environment than if we attempted to record every possible variable in the environment. For example, concentrations of ozone depleting substances (ODS) in the atmosphere, tracked over time, is a good indicator with respect to the environmental issue of stratospheric ozone depletion. Environmental indicators have been defined in different ways but common themes exist. “An environmental indicator is a numerical value that helps provide insight into the state of the environment or human health. Indicators are developed based on quantitative measurements or statistics of environmental condition that are tracked over time. Environmental indicators can be developed and used at a wide variety of geographic scales, from local to regional to national levels.” “A parameter ...

Economic Indicator
An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries: for example, the unemployment rate, quits rate (quit rate in American English), housing starts, consumer price index (a measure for inflation), Inverted yield curve, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet penetration, retail sales, price index, and money supply changes. The leading business cycle dating committee in the United States of America is the private National Bureau of Economic Research. The Bureau of Labor Statistics is the principal fact-finding agency for the U.S. government in the field of labor economics and statistics. Other producers of economic indicators includes the United Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeyguide
Honeyguides (family Indicatoridae) are near passerine birds in the order Piciformes. They are also known as indicator birds, or honey birds, although the latter term is also used more narrowly to refer to species of the genus '' Prodotiscus''. They have an Old World tropical distribution, with the greatest number of species in Africa and two in Asia. These birds are best known for their interaction with humans. Honeyguides are noted and named for one or two species that will deliberately lead humans (but, contrary to popular claims, not honey badgers) directly to bee colonies, so that they can feast on the grubs and beeswax that are left behind. Description Most honeyguides are dull-colored, though some have bright yellow coloring in the plumage. All have light outer tail feathers, which are white in all the African species. The smallest species by body mass appears to be the green-backed honeyguide, at an average of , and by length appears to be the Cassin's honeyguide, at ...

Health Indicator
Health indicators are quantifiable characteristics of a population which researchers use as supporting evidence for describing the health of a population. Typically, researchers will use a survey methodology to gather information about a population sample, use statistics in an attempt to generalize the information collected to the entire population, and then use the statistical analysis to make a statement about the health of the population. Health indicators are often used by governments to guide health care policy or to make goals for improving population health. Characteristics A health indicator which will be used internationally to describe global health should have the following characteristics: #It should be defined in such a way that it can be measured uniformly internationally. #It must have statistical validity. #The indicator must be data which can feasibly be collected in a reasonable amount of time. #The analysis of the data must result in a recommendation on which p ...

Indicator (Onward To Olympas Album)
''Indicator'' is the third and final studio album from Onward to Olympas. Facedown Records released the album on October 9, 2012. Onward to Olympas worked with Taylor Larson, in the production of this album. Critical reception Awarding the album two stars from ''Alternative Press'', Dan Slessor states, "''Indicator'' is a record for the already converted, and there’s nothing wrong with that, per se." Ian Webber, rating the album a seven out of ten for Cross Rhythms, writes, "With this release OTO have produced a competent third recording. It may well be lost amongst more established acts but will certainly be appreciated by their fans." Giving the album four stars at Jesus Freak Hideout, Scott Fryberger says, "Onward To Olympas have another solid hardcore album in ''Indicator''." Jonathan Anderson, awarding the album two and a half stars by The New Review, describes, "''Indicator'' simply has not reached the bar set by its predecessors."

Indicator Organism
Indicator organisms are used as a proxy to monitor conditions in a particular environment, ecosystem, area, habitat, or consumer product. Certain bacteria, fungi and helminth eggs are being used for various purposes. Types Indicator bacteria Certain bacteria can be used as indicator organisms in particular situations, such as when present in bodies of water. Indicator bacteria themselves may not be pathogenic but their presence in waste may indicate the presence of other pathogens. Similar to how there are various types of indicator organisms, there are also various types of indicator bacteria. The most common indicators are total coliforms, fecal coliforms, E. coli, and enterococci. The presence of bacteria commonly found in human feces, termed coliform bacteria (e.g. '' E. coli''), in surface water is a common indicator of faecal contamination. The means by which pathogens found in fecal matter can enter recreational bodies of water include, but are not limited to, sewage, s ...

Performance Indicator
A performance indicator or key performance indicator (KPI) is a type of performance measurement. KPIs evaluate the success of an organization or of a particular activity (such as projects, programs, products and other initiatives) in which it engages. KPIs provide a focus for strategic and operational improvement, create an analytical basis for decision making and help focus attention on what matters most. Often success is simply the repeated, periodic achievement of some levels of operational goal (e.g. zero defects, 10/10 customer satisfaction), and sometimes success is defined in terms of making progress toward strategic goals. Accordingly, choosing the right KPIs relies upon a good understanding of what is important to the organization. What is deemed important often depends on the department measuring the performance – e.g. the KPIs useful to finance will differ from the KPIs assigned to sales. Since there is a need to understand well what is important, various techniques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...

Ecological Indicator
Ecological indicators are used to communicate information about ecosystems and the impact human activity has on ecosystems to groups such as the public or government policy makers. Ecosystems are complex and ecological indicators can help describe them in simpler terms that can be understood and used by non-scientists to make management decisions. For example, the number of different beetle taxa found in a field can be used as an indicator of biodiversity. Many different types of indicators have been developed. They can be used to reflect a variety of aspects of ecosystems, including biological, chemical and physical. Due to this variety, the development and selection of ecological indicators is a complex process. Using ecological indicators is a pragmatic approach since direct documentation of changes in ecosystems as related to management measures, is cost and time intensive. For example, it would be expensive and time-consuming to count every bird, plant and animal in a newly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redox Indicator
A redox indicator (also called an oxidation-reduction indicator) is an indicator which undergoes a definite color change at a specific electrode potential. The requirement for fast and reversible color change means that the oxidation-reduction equilibrium for an indicator redox system needs to be established very quickly. Therefore, only a few classes of organic redox systems can be used for indicator purposes. There are two common classes of redox indicators: * metal complexes of phenanthroline and bipyridine. In these systems, the metal changes oxidation state. * organic redox systems such as methylene blue. In these systems, a proton participant in the redox reaction. Therefore, sometimes redox indicators are also divided into two general groups: independent or dependent on pH. The most common redox indicator are organic compounds. Redox Indicator example: The molecule 2,2'- Bipyridine is a redox Indicator. In solution, it changes from light blue to red at an electrode po ...
