Accident models
Many models to characterize and analyze accidents have been proposed, which can be classified by type. No single model is the sole correct approach. Notable types and models include:
Sequential models
Domino Theory
Loss Causation Model
Complex linear models
Energy Damage Model
Time sequence models
Generalized Time Sequence Model
Accident Evolution and Barrier Function
Epidemiological models
Gordon 1949
Onward Mappings Model based on Resident Pathogens Metaphor
Process model
Benner 1975
Systemic models
Rasmussen
Reason Model of System Safety (embedding the Swiss cheese model)
Healthcare error proliferation model
Human reliability
Woods, 1994
Non-linear models
System accident
Systems-Theoretic Accident Model and Process (STAMP)
Functional Resonance Analysis Method (FRAM)
Assertions that all existing models are insufficientIshikawa diagrams are sometimes used to illustrate root-cause analysis and five whys discussions. See also

Having an income below the poverty line, which is defined as an income needed to purchase basic needs, is also referred to as primary proverty. The "dollar a day" poverty line was first introduced in 1990 as a measure to meet such standards of living. For nations that do not use the US dollar as currency, "dollar a day" does not translate to living a day on the equivalent amount of local currency as determined by the exchange rate. Rather, it is determined by the purchasing power parity rate, which would look at how much local currency is needed to buy the same things that a dollar could buy in the United States. Usually, this would translate to having less local currency than if the exchange rate was used as the United States is a relatively more expensive country.From 1993 through 2005, the World Bank defined absolute poverty as $1.08 a day on such a purchasing power parity basis, after adjusting for inflation to the 1993 US dollar and in 2008, it was updated as $1.25 a day (equivalent to $1.00 a day in 1996 US prices) and in 2015, it was updated as living on less than US$1.90 per day, and moderate poverty as less than $2 or $5 a day. Similarly, ultra-poverty is defined by a 2007 report issued by International Food Policy Research Institute as living on less than 54 cents per day. The poverty line threshold of $1.90 per day, as set by the World Bank, is controversial.
