Attrition Warfare
Attrition warfare is a military strategy consisting of belligerent attempts to win a war by wearing down the enemy to the point of collapse through continuous losses in personnel and materiel. The word ''attrition'' comes from the Latin root , meaning "to rub against", similar to the "grinding down" of the opponent's forces in attrition warfare. Strategic considerations Attrition warfare represents an attempt to grind down an opponent's ability to make war by destroying their military resources by any means including guerrilla warfare, people's war, scorched earth and all kind of battles apart from a decisive battle. Attrition warfare does not include all kinds of Blitzkrieg or using concentration of force and a decisive battle to win. The side that reinforces their army at a higher speed will normally win the war. Clausewitz called it the exhaustion of the adversary. A side that perceives itself to be at a marked disadvantage may deliberately seek out attrition warfare to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Of Attrition
The War of Attrition ( ar, حرب الاستنزاف, Ḥarb al-Istinzāf; he, מלחמת ההתשה, Milhemet haHatashah) involved fighting between Israel and Egypt, Jordan, the Palestine Liberation Organisation (PLO) and their allies from 1967 to 1970. Following the 1967 Six-Day War, no serious diplomatic efforts tried to resolve the issues at the heart of the Arab–Israeli conflict. The 1967 Arab League summit formulated in September the " three no's" policy: barring peace, recognition or negotiations with Israel. The Egyptian President Gamal Abdel Nasser believed that only military initiative would compel Israel or the international community to facilitate a full Israeli withdrawal from Sinai, and hostilities soon resumed along the Suez Canal. These initially took the form of limited artillery duels and small-scale incursions into Sinai, but by 1969, the Egyptian Army judged itself prepared for larger-scale operations. On March 8, 1969, Nasser proclaimed the offi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Of Attrition (game)
In game theory, the ''war of attrition'' is a dynamic timing game in which players choose a time to stop, and fundamentally trade off the strategic gains from outlasting other players and the real costs expended with the passage of time. Its precise opposite is the ''pre-emption game'', in which players elect a time to stop, and fundamentally trade off the strategic costs from outlasting other players and the real gains occasioned by the passage of time. The model was originally formulated by John Maynard Smith; a mixed evolutionarily stable strategy (ESS) was determined by Bishop & Cannings. An example is a second price ''all-pay'' auction, in which the prize goes to the player with the highest bid and each player pays the loser's low bid (making it an all-pay sealed-bid second-price auction). Examining the game To see how a war of attrition works, consider the all pay auction: Assume that each player makes a bid on an item, and the one who bids the highest wins a resource of ...

Withdrawal (military)
A tactical withdrawal or retreating defensive action is a type of military operation, generally meaning that retreating forces draw back while maintaining contact with the enemy. A withdrawal may be undertaken as part of a general retreat, to consolidate forces, to occupy ground that is more easily defended, force the enemy to overextend to secure a decisive victory, or to lead the enemy into an ambush. It is considered a relatively risky operation, requiring discipline to keep from turning into a disorganized rout or at the very least doing severe damage to the military's morale. Tactical withdrawal A withdrawal may be anticipated, as when a defending force is outmatched or on disadvantageous ground, but must cause as much damage to an enemy as possible. In such a case, the retreating force may employ a number of tactics and strategies to further impede the enemy's progress. This could include setting mines or booby traps during or before withdrawal, leading the enemy int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attrition (research)
In science, attrition are ratios regarding the loss of participants during an experiment. Attrition rates are values that indicate the participant drop out. Higher attrition rates are found in longitudinal studies.

Attrition (dental)
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging. Advanced and excessive wear and tooth surface loss can be defined as pathological in nature, requiring intervention by a dental practitioner. The pathological wear of the tooth surface can be caused by bruxism, which is clenching and grinding of the teeth. If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an early stage to prevent unnecessary loss of tooth structure as enamel does not regenerate. Signs and symptoms Attrition occurs as a result of opposing tooth surfaces contacting. The contact can affect cuspal, incisal and proximal surface areas. Indicati ...

Attrition (erosion)
Attrition is the process of erosion that occurs during rock collision and transportation. The transportation of sediment chips and smooths the surfaces of bedrock; this can be through water or wind. Rocks undergoing attrition erosion are often found on or near the bed of a stream. Attrition is also partially responsible for turning boulders into smaller rocks and eventually to sand. Attrition erosion allows past and present geologic changes to be understood as well as paleogeomorphic environments to be interpreted. Researchers use particle shapes (a result of attrition) to study erosion and environmental changes. Mechanism The amount of attrition is dependent on a number of factors: particle properties such as size, shape, surface, porosity, hardness, and cracks, as well as environmental properties such as time, velocity, pressure, shear, and temperature. Generally, particles are more affected by attrition farther downstream, as the rivers' velocity tends to be higher, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attrition (film)
''Attrition'', also known as ''Final Mission'', is a 2018 American Wing Chun film directed by Mathieu Weschler and produced by Saradan Media based on a screenplay by Steven Seagal.

Imperfect Contrition
In Christianity, contrition or contriteness (, i.e. crushed by guilt) is repentance for sins one has committed. The remorseful person is said to be ''contrite''. A central concept in much of Christianity, contrition is regarded as the first step, through Christ, towards reconciliation with God. It consists of repentance for all one's sins, a desire for God over sin, and faith in Christ's redemption on the cross and its sufficiency for salvation (see regeneration and '' ordo salutis''). It is widely referred to throughout the Bible, e.g. Ezekiel 33:11, Psalms 6:7ff, Psalm 51:1–12, Luke 13:5, Luke 18:9–13, and the well-known parable of the prodigal son (Luke 15:11–32). In the Catholic Church Nature The Council of Trent defined contrition as "sorrow of soul, and a hatred of sin committed, with a firm purpose of not sinning in the future". It is also known as ''animi cruciatus'' (affliction of spirit) and ''compunctio cordis'' (repentance of heart). The word "contriti ...

Customer Attrition
Customer attrition, also known as customer churn, customer turnover, or customer defection, is the loss of clients or customers. Banks, telephone service companies, Internet service providers, pay TV companies, insurance firms, and alarm monitoring services, often use customer attrition analysis and customer attrition rates as one of their key business metrics (along with cash flow, EBITDA, etc.) because the cost of retaining an existing customer is far less than acquiring a new one. Companies from these sectors often have customer service branches which attempt to win back defecting clients, because recovered long-term customers can be worth much more to a company than newly recruited clients. Companies usually make a distinction between voluntary churn and involuntary churn. Voluntary churn occurs due to a decision by the customer to switch to another company or service provider, involuntary churn occurs due to circumstances such as a customer's relocation to a long-term ca ...

Language Attrition
Language attrition is the process of losing a native or first language. This process is generally caused by both isolation from speakers of the first language ("L1") and the acquisition and use of a second language ("L2"), which interferes with the correct production and comprehension of the first. Such interference from a second language is probably experienced to some extent by all bilinguals, but is most evident among speakers for whom a language other than their first has started to play an important, if not dominant, role in everyday life; these speakers are more likely to experience language attrition. It is common among immigrants that travel to countries where languages foreign to them are used. There are several factors which affect the process. Frequent exposure and use of a particular language is often assumed adequate to maintain the native language system intact. However, research has often failed to confirm this prediction. A positive attitude towards the potentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Language Attrition
Second-language attrition is the decline of second-language skills, which occurs whenever the learner uses the second language to an insufficient degree ( de Bot & Weltens 1991:43) or due to environmental changes the language use is limited and another language is becoming the dominant one (Olshtain 1989: 151). Definition A German researcher, Schöpper-Grabe, once expressed that, "Almost everybody who has learned a foreign language shares the experience of forgetting the acquired language skills once the period of formal instruction is over" (Schöpper-Grabe 1998: 231). This relates to how second-language attrition can be defined as the "non-pathological decrease in a language that had formerly been acquired by an individual" (Köpke & Schmid 2004: 5) and described as the " loss of skills in the individual over time" (de Bot & Weltens, 1995). Beginning in the 1970s until today, a new and especially young field in the area of second-language acquisition was developed. It is co ...
