Fish Mortality
Fish mortality is a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death. The mortality can be divided into two types: * Natural mortality: the removal of fish from the stock due to causes not associated with fishing. Such causes can include disease, competition, cannibalism, old age, predation, pollution or any other natural factor that causes the death of fish. In fisheries models natural mortality is denoted by (M).Sparre, P.; Ursin E.and Venema S. C. (1989). Introduction to tropical fish stock assessment. Part 1- Manual. FAO Fisheries Technical Paper No. 3061. Rome, FAO. p. 337. * Fishing mortality: the removal of fish from the stock due to fishing activities using any fishing gear. It is denoted by (F) in fisheries models. (M) and (F) are additive instantaneous rates that sum up to (Z), the instantaneous total mortality coefficient; that is, Z=M+F.Gulland, J.A. (1969).

Mortality (book)
''Mortality'' is a 2012, posthumously published book by Anglo-American writer Christopher Hitchens. It comprises seven essays which first appeared in '' Vanity Fair'' concerning his struggle with esophageal cancer, with which he was diagnosed during his 2010 book tour and which killed him in December 2011. An eighth chapter consisting of unfinished "fragmentary jottings", a foreword by Graydon Carter (Hitchens' '' Vanity Fair'' editor) and an afterword by Carol Blue (Hitchens' widow), are also included in the publication. Description Hitchens held the post of contributing editor at '' Vanity Fair'' from November 1992 until his death. In this capacity he contributed about 10 essays per year on subjects as diverse as politics and the limits of self-improvement, writing about "anything except sports". Therefore, he felt obliged when he was asked to write about his illness for the magazine, and managed to dispatch seven essays from "Tumourville" before he was overcome by his illn ...

Mortality (computability Theory)
In computability theory, the mortality problem is a decision problem related to the halting problem. For Turing machines, the halting problem can be stated as follows: ''Given a Turing machine A Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is capable of implementing any computer algori ..., and an input, decide whether the machine halts when run on the given input.'' In contrast, the mortality problem for Turing machines asks whether ''all'' executions of the machine, starting from ''any configuration'', halt. In the statement above, a ''configuration'' specifies both the machine's state (not necessarily its initial state), its tape position and the contents of the tape. While we usually assume that in the starting configuration all but finitely many cells on the tape are blanks, in the mortality problem the tape can have arb ...

Mortality Rate
Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular Statistical population, population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or Incidence (epidemiology), incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. , for instance, the Central Intelligence Agency, CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population p ...

Internal Validity
Internal validity is the extent to which a piece of evidence supports a claim about cause and effect, within the context of a particular study. It is one of the most important properties of scientific studies and is an important concept in reasoning about evidence more generally. Internal validity is determined by how well a study can rule out alternative explanations for its findings (usually, sources of systematic error or 'bias'). It contrasts with external validity, the extent to which results can justify conclusions about other contexts (that is, the extent to which results can be generalized). Both internal and external validity can be described using qualitative or quantitative forms of causal notation. Details Inferences are said to possess internal validity if a causal relationship between two variables is properly demonstrated.Shadish, W., Cook, T., and Campbell, D. (2002).

Case Fatality Rate
In epidemiology, case fatality rate (CFR) – or sometimes more accurately case-fatality risk – is the proportion of people who have been diagnosed with a certain disease and end up dying of it. Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death. A CFR is generally expressed as a percentage. It is a measure of disease lethality, and thus may change with different treatments. CFRs are most often used for with discrete, limited-time courses, such as acute infections. Terminology The ''mortality rate'' – often confused with the CFR – is a measure of the relative number of deaths (either in general, or due to a specific cause) within the entire population per unit of time. A CFR, in contrast, is the number of deaths among the number of diagnosed cases only, regardless of time or total population. From a mathematical point of view, by taking values between 0 and 1 or 0% and 100%, CFRs are actually a measure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cause Of Death
In law, medicine, and statistics, cause of death is an official determination of the conditions resulting in a human's death, which may be recorded on a death certificate. A cause of death is determined by a medical examiner. In rare cases, an autopsy needs to be performed by a pathologist. The cause of death is a specific disease or injury, in contrast to the manner of death, which is a small number of categories like "natural", "accident", "suicide", and "homicide", each with different legal implications. International Classification of Disease (ICD) codes can be used to record manner and cause of death in a systematic way that makes it easy to compile statistics and more feasible to compare events across jurisdictions.National Center for Health Statistics �Classification of Death and Injury Resulting from Terrorism – How are external cause of injury codes assigned?

Fulminant
Fulminant () is a medical descriptor for any event or process that occurs suddenly and escalates quickly, and is intense and severe to the point of lethality, i.e., it has an explosive character. The word comes from Latin ''fulmināre'', to strike with lightning. There are several diseases described by this adjective: * Fulminant liver failure * Fulminant (Marburg variant) multiple sclerosis * Fulminant colitis * Fulminant pre-eclampsia * Fulminant meningitis * Purpura fulminans * Fulminant hepatic venous thrombosis ( Budd-Chiari syndrome) * Fulminant jejunoileitis * Fulminant myocarditis Beyond these particular uses, the term is used more generally as a descriptor for sudden-onset medical conditions that are immediately threatening to life or limb. Some viral hemorrhagic fevers, such as Ebola, Lassa fever, and Lábrea fever, may kill in as little as two to five days. Diseases that cause rapidly developing lung edema, such as some kinds of pneumonia, may kill in a few h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortality Displacement
In epidemiology, the excess deaths or excess mortality is a measure of the increase in the number of deaths during a time period and/or in a certain group, as compared to the expected value or statistical trend during a reference period (typically of five years) or in a reference population. It may typically be measured in percentage points, or in number of deaths per time unit. A short period of excess mortality that is followed by a compensating period of mortality deficit (i.e., fewer deaths than expected, because those people have died at a younger age) is quite common, and is also known as "harvesting". Mortality deficit in a particular time period can be caused by deaths displaced to an earlier time (due to harvesting by an event in the past) or deaths displaced to a future time (due to lives being saved, also called "avoided mortality"). Mortality displacement is the occurrence of deaths at an earlier time than they would have otherwise occurred, meaning the deaths are '' ...

Mortality Salience
Mortality salience is the awareness that one's death is inevitable and that all attempts to defer it indefinitely are ultimately futile. The term derives from terror management theory, which proposes the so-called mortality salience hypothesis: mortality salience causes existential anxiety that may be buffered by one's cultural worldview and/or a sense of self-esteem. Terror management theory Mortality salience engages the conflict humans have to face both their instinct to avoid death completely, and their intellectual knowledge that avoiding death is ultimately futile. According to terror management theory, when human beings begin to contemplate their mortality and their vulnerability to death, feelings of terror emerge because of the simple fact that humans want to avoid their inevitable death. Mortality salience comes into effect because humans contribute all of their actions to either avoiding death or distracting themselves from contemplating it. Thus, terror management ...
