Reversal (law)
In law, an appeal is the process in which Legal case, cases are reviewed by a higher authority, where parties request a formal change to an official decision. Appeals function both as a process for error correction as well as a process of clarifying and interpreting law. Although appellate courts have existed for thousands of years, common law countries did not incorporate an affirmative right to appeal into their jurisprudence until the 19th century. Terminology American English and British English have diverged significantly on the topic of appellate terminology. American cases go up "on appeal" and one "appeals from" (Intransitive verb, intransitive) or "appeals" (Transitive verb, transitive) an order, award, judgment, or conviction, while decisions of British courts are said to be "under appeal" and one "appeals against" a judgment. An American court disposes of an appeal with words like "judgment affirmed" (the appeal is without merit) or "judgment reversed" (the app ...

Reversal Test
The reversal test is a heuristic designed to spot and eliminate status quo bias, an emotional bias irrationally favouring the current state of affairs. The test is applicable to the evaluation of any decision involving a potential deviation from the status quo along some continuous dimension. The reversal test was introduced in the context of the bioethics of human enhancement by Nick Bostrom and Toby Ord. Concept Bostrom and Ord introduced the reversal test to provide an answer to the question of how one can, given that humans might suffer from irrational status quo bias, distinguish between valid criticisms of a proposed increase in some human trait and criticisms merely motivated by resistance to change. The reversal test attempts to do this by asking whether it would be a good thing if the trait was ''decreased'': An example given is that if someone objects that an increase in intelligence would be a bad thing due to more dangerous weapons being made etc., the objector to that ...

Reversal (options)
Options arbitrage is a trading strategy using arbitrage in the options market to earn small profits with very little or zero risk. Traders perform conversions when options are relatively overpriced by purchasing stock and selling the equivalent options position. When the options are relatively underpriced, traders will do reverse conversions or reversals. In practice, actionable option arbitrage opportunities have decreased with the advent of automated trading strategies. Conversion A ''conversion'' position is: * short a call, * long a put, and * long the underlying The call and put have the same strike value and expiration date. The resulting portfolio is delta neutral. One reason a trader may take this position would be to extend the holding period of the underlying position for capital gains tax purposes, while locking in the current price. Reversal A ''reversal'' (or reverse conversion) position is: * long a call, * short a put, and * short the underlying. Th ...

Formal Language
In logic, mathematics, computer science, and linguistics, a formal language is a set of strings whose symbols are taken from a set called "alphabet". The alphabet of a formal language consists of symbols that concatenate into strings (also called "words"). Words that belong to a particular formal language are sometimes called ''well-formed words''. A formal language is often defined by means of a formal grammar such as a regular grammar or context-free grammar. In computer science, formal languages are used, among others, as the basis for defining the grammar of programming languages and formalized versions of subsets of natural languages, in which the words of the language represent concepts that are associated with meanings or semantics. In computational complexity theory, decision problems are typically defined as formal languages, and complexity classes are defined as the sets of the formal languages that can be parsed by machines with limited computational power.

Peripeteia
Peripeteia (, peripety, alternative Latin form: Peripetīa, ultimately from ) is a reversal of circumstances, or turning point, within a work of literature. Aristotle's view Aristotle, in his '' Poetics'', defines peripeteia as "a change by which the action veers round to its opposite, subject always to our rule of probability or necessity." According to Aristotle, peripeteia, along with discovery, is the most effective when it comes to drama, particularly in a tragedy. He wrote that "The finest form of Discovery is one attended by Peripeteia, like that which goes with the Discovery in Oedipus...". Aristotle says that peripeteia is the most powerful part of a plot in a tragedy along with discovery ( anagnorisis). A peripety is the change of the kind described from one state of things within the play to its opposite, and that too in the way we are saying, in the probable or necessary sequence of events. There is often no element like Peripeteia; it can bring forth or result in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Reversal
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones. Reverse thrust is also available on many Propeller (aircraft), propeller-driven aircraft through reversing the Variable-pitch propeller (aeronautics), controllable-pitch propellers to a negative angle. The equivalent concept for a ship is called astern propulsion. Principle and uses A landing roll consists of touchdown, bringing the aircraft to taxi speed, and eventually to a complete stop. However, most commercial jet engines continue to prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Reversal
"In Soviet Russia", also called the Russian reversal, is a joke template taking the general form "In America you do ''X'' to/with ''Y''; in Soviet Russia ''Y'' does ''X'' to/with you". Typically the American clause describes a harmless ordinary activity and the inverted Soviet form something menacing or dysfunctional, satirizing life under communist rule, or in the "old country". Sometimes the first clause is omitted, and sometimes either clause or both are deliberately rendered with English grammatical errors stereotypical of Russians. Although the exact origin of the joke form is uncertain, an early example is from the 1938 Cole Porter musical '' Leave It to Me!'' ("In Soviet Russia, messenger tips you."). Bob Hope used the form at the 1958 Academy Awards. In the 1968–1973 television show ''Laugh-In'', a recurring character, "Piotr Rosmenko the Eastern European Man" (played by Arte Johnson), delivered short jokes such as "Here in America, is very good, everyone watch televi ...

Role Reversal
Role reversal is a psychotherapeutic technique in psychodrama that demonstrates a protagonist's intrapersonal conflicts deeply and explicitly on the stage. This technique is perhaps the single most important and effective technique in psychodrama.Greenberg, Ira A. (1974) Psychodrama: theory and Therapy, New York: Behavioral Publications. In the form of psychodrama, the protagonist is invited to move out of their own position or role into the significant other's position and enact that role.Moreno, J.L. (1952) Psychodramatic Production Techniques. Group Psychotherapy, Psychodrama & Sociometry. (4):273-303. Therefore, the auxiliary ego can observe and learn how to play the role. For example, in a parent-child's session, a protagonist who is the child reverses role with one of their parents. This technique not only helps the protagonist get more insight of a specific role but also helps the director, the auxiliary egos, and the audience learn more about that specific role.

Risk Reversal
In finance, risk reversal (also known as a ''conversion'' when an investment strategy) can refer to a measure of the volatility skew or to a trading strategy. Risk reversal investment strategy A risk-reversal is an option position that consists of selling (that is, being short) an out of the money put and buying (i.e. being long) an out of the money call, both options expiring on the same expiration date. In this strategy, the investor will first form their market view on a stock or an index; if that view is bullish they will want to go long. However, instead of going long on the stock, they will buy an out of the money call option, and simultaneously sell an out of the money put option, using the money from the sale of the put option to purchase the call option. Then as the stock goes up in price, the call option will be worth more, and the put option will be worth less.http://www.quantprinciple.com/invest/index.php/docs/quant_strategies/riskreversal/ Theory of Risk Revers ...

Reversal Theory
Reversal theory is a structural, phenomenological theory of personality, motivation, and emotion in the field of psychology. It focuses on the dynamic qualities of normal human experience to describe how a person regularly reverses between psychological states, reflecting their motivational style, the meaning they attach to a situation at a given time, and the emotions they experience. Introduction Unlike many theories related to personality, reversal theory does not consist of static traits (trait theory), but rather a set of dynamic motivational states. As people cycle through states, they will see different things as important, experience different emotions, react differently, and look for quite different rewards. Motivation drives orientation, styles, perspective, and desires. The theory emphasizes the changeability of human nature. Hundreds of empirical papers have been published testing, or using, one or another idea from the theory. It has also generated over twenty books, ...

Reversal Film
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German, Romanian or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astr ...

This style of wrestling is also practiced at the Secondary school, high school, middle school, and Elementary schools in the United States, elementary levels with Scholastic wrestling, some modifications. The rules and style of collegiate/folkstyle wrestling differ from the Olympic wrestling, Olympic styles of Freestyle wrestling, freestyle and Greco-Roman wrestling. There are collegiate wrestling programs in almost all U.S. states, and one Simon Fraser Red Leafs#Wrestling, university in Canada. Women's wrestling at the U.S. college level uses two different rulesets.
