Displacement (geometry)
In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. A displacement may be identified with the translation that maps the initial position to the final position. Displacement is the shift in location when an object in motion changes from one position to another. For motion over a given interval of time, the displacement divided by the length of the time interval defines the average velocity (a vector), whose magnitude is the average speed (a scalar quantity). Formulation A displacement may be formulated as a '' relative position'' (resulting from the motion), that is, as the final position of a point relative to its initial position . The corresponding displacement vector can be defined as the diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Displacement Reaction
A salt metathesis reaction (also called a double displacement reaction, double replacement reaction, or double decomposition) is a type of chemical reaction in which two ionic compounds in aqueous solution exchange their component ions to form two new compounds. Often, one of these new compounds is a precipitate, gas, or weak electrolyte, driving the reaction forward. :AB + CD -> AD + CB \mathitA_\mathitD_\mathit + \mathitC_\mathitB_\mathit --> In older literature, the term double decomposition is common. The term double decomposition is more specifically used when at least one of the substances does not dissolve in the solvent, as the ligand or ion exchange takes place in the solid state of the reactant. For example: :AX(aq) + BY(s) → AY(aq) + BX(s). Types of reactions Counterion exchange Salt metathesis is a common technique for exchanging counterions. The choice of reactants is guided by a solubility chart or lattice energy. HSAB theory can also be used to predict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Child Displacement
Child displacement is the complete removal or separation of children from their parents and immediate family or settings in which they have initially been reared. Displaced children includes varying categories of children who experience separation from their families and social settings due to several varied reasons. These populations include children separated from their parents, refugees,Alfredson, Lisa, (2002) 'Child Soldiers, Displacement and Human Security', 4 Disarmament Forum pp. l 7-27 children sent to boarding schools,CWAB - Session 6.2 - Reasons for displacement European Union – Canada project Child welfare across borders (2003) internally displaced persons or IDPs, ...

Layoff
A layoff or downsizing is the temporary suspension or permanent termination of employment of an employee or, more commonly, a group of employees (collective layoff) for business reasons, such as personnel management or downsizing an organization. Originally, ''layoff'' referred exclusively to a temporary interruption in work, or employment but this has evolved to a permanent elimination of a position in both British and US English, requiring the addition of "temporary" to specify the original meaning of the word. A layoff is not to be confused with Wrongful dismissal, wrongful termination. ''Laid off workers'' or ''displaced workers'' are workers who have lost or left their jobs because their employer has closed or moved, there was insufficient work for them to do, or their position or Shift work, shift was abolished (Borbely, 2011). Downsizing in a company is defined to involve the reduction of employees in a workforce. Downsizing in companies became a popular practice in the 1 ...

Displacement (fencing)
In fencing Fencing is a combat sport that features sword fighting. It consists of three primary disciplines: Foil (fencing), foil, épée, and Sabre (fencing), sabre (also spelled ''saber''), each with its own blade and set of rules. Most competitive fe ..., displacement is a movement that avoids or dodges an attack. Fencers commonly use displacement when attacking while not having priority. Attacking into the opponent's right-of-way is known as a ''counter-attack''. If both fencers land, the fencer with priority, the attacker, is awarded the touch; therefore, the goal of the displacement is to hit the opponent while avoiding being hit in return. Displacement can take the form of retreating, advancing past the enemy's blade, utilising a flèche, ducking, or even stepping off the piste. References Fencing {{Fencing-stub ...

Gentrification
Gentrification is the process whereby the character of a neighborhood changes through the influx of more Wealth, affluent residents (the "gentry") and investment. There is no agreed-upon definition of gentrification. In public discourse, it has been used to describe a wide array of phenomena, sometimes in a pejorative connotation. Gentrification is a common and controversial topic in urban politics and urban planning, planning. Gentrification often increases the Value (economics), economic value of a neighborhood, but can be controversial due to changing Demography, demographic composition and potential displacement of incumbent residents. Gentrification is more likely when there is an undersupply of housing and rising home values in a metropolitan area. The gentrification process is typically the result of increasing attraction to an area by people with higher incomes spilling over from neighboring cities, towns, or neighborhoods. Further steps are increased Socially responsib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Development-induced Displacement
Development-induced displacement and resettlement (DIDR) occurs when people are forced to leave their homes in a development-driven form of forced migration. Historically, it has been associated with the construction of dams for hydroelectric power and irrigation, but it can also result from various development projects such as mining, agriculture, the creation of military installations, airports, industrial plants, weapon testing grounds, railways, road developments, urbanization, conservation projects, and forestry. Development-induced displacement is a social problem affecting multiple levels of human organization, from tribal and village communities to well-developed urban areas. Development is widely viewed as an inevitable step towards modernization and economic growth in developing countries; however, for those who are displaced, the result is most often loss of livelihood and impoverishment. Classification of development-induced displaced persons (DIDPs), refugees and inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (parapsychology)
Parapsychology is the study of alleged psychic phenomena (extrasensory perception, telepathy, teleportation, precognition, clairvoyance, psychokinesis (also called telekinesis), and psychometry) and other paranormal claims, for example, those related to near-death experiences, synchronicity, apparitional experiences, etc. Criticized as being a pseudoscience, the majority of mainstream scientists reject it. Parapsychology has been criticised for continuing investigation despite being unable to provide reproducible evidence for the existence of any psychic phenomena after more than a century of research. Parapsychology research rarely appears in mainstream scientific journals; a few niche journals publish most papers about parapsychology. Terminology The term ''parapsychology'' was coined in 1889 by philosopher Max Dessoir as the German . It was adopted by J. B. Rhine in the 1930s as a replacement for the term ''psychical research'' to indicate a significant shift toward exper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (psychology)
In psychology, displacement () is an Unconscious mind, unconscious defence mechanism whereby the mind substitutes either a new aim or a new Object relations theory, object for things felt in their original form to be dangerous or unacceptable. Example: If your boss criticizes you at work, you might feel angry but can't express it directly to your boss. Instead, when you get home, you take out your frustration by yelling at a family member or slamming a door. Here, the family member or the door is a safer target for your anger than your boss. Freud The concept of displacement originated with Sigmund Freud. Initially he saw it as a means of dream-distortion, involving a shift of emphasis from important to unimportant elements, or the replacement of something by a mere illusion. Freud called this “displacement of accent.” Displacement of object: Feelings that are connected with one person are displaced onto another person. A man who has had a bad day at the office, comes home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forced Displacement
Forced displacement (also forced migration or forced relocation) is an involuntary or coerced movement of a person or people away from their home or home region. The UNHCR defines 'forced displacement' as follows: displaced "as a result of persecution, conflict, generalized violence or human rights violations". A forcibly displaced person may also be referred to as a "forced migrant", a "displaced person" (DP), or, if displaced within the home country, an " internally displaced person" (IDP). While some displaced persons may be considered refugees, the latter term specifically refers to such displaced persons who are receiving legally-defined protection and are recognized as such by their country of residence and/or international organizations. Forced displacement has gained attention in international discussions and policy making since the European migrant crisis. This has since resulted in a greater consideration of the impacts of forced migration on affected regions outsid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (linguistics)
In linguistics, displacement is the capability of language to communicate about things that are not immediately present (spatially or temporally); i.e., things that are either not here or are not here now. In 1960, Charles F. Hockett proposed displacement as one of 13 design features of language that distinguish human language from animal communication systems (ACSs): In animal communication systems Honeybees use the waggle dance to communicate the location of a patch of flowers suitable for foraging. The degree of displacement in this example remains limited when compared to human language. A bee can only communicate the location of the most recent food source it has visited. It cannot communicate an idea about a food source at a specific point in the past, nor can it speculate about food sources in the future. In addition, displacement in the waggle dance is restricted by the language's lack of creativity and productivity. The bees can express direction and distance, but it ...
