Fidelity
Fidelity is the quality of faithfulness or loyalty. Its original meaning regarded duty in a broader sense than the related concept of ''fealty''. Both derive from the Latin word ''fidēlis'', meaning "faithful or loyal". In the City of London financial markets it has traditionally been used in the sense encompassed in the motto "My word is my bond". Audio and electronics In audio, "fidelity" denotes how accurately a copy reproduces its source. In the 1950s, the terms " high fidelity" or "hi-fi" were popularized for equipment and recordings which exhibited more accurate sound reproduction. For example, a worn gramophone record will have a lower fidelity than one in good condition, and a recording made by a low budget record company in the early 20th century is likely to have significantly less audio fidelity than a good modern recording. Similarly in electronics, fidelity refers to the correspondence of the output signal to the input signal, rather than sound quality, as i ...

Wi-Fi
Wi-Fi () is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide visitors with Internet access for their mobile devices. ''Wi-Fi'' is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term ''Wi-Fi Certified'' to products that successfully complete interoperability certification testing. the Wi-Fi Alliance consisted of more than 800 companies from around the world. over 3 ...

Translation
Translation is the communication of the Meaning (linguistic), meaning of a #Source and target languages, source-language text by means of an Dynamic and formal equivalence, equivalent #Source and target languages, target-language text. The English language draws a terminology, terminological distinction (which does not exist in every language) between ''translating'' (a written text) and ''Language interpretation, interpreting'' (oral or Sign language, signed communication between users of different languages); under this distinction, translation can begin only after the appearance of writing within a language community. A translator always risks inadvertently introducing source-language words, grammar, or syntax into the target-language rendering. On the other hand, such "spill-overs" have sometimes imported useful source-language calques and loanwords that have enriched target languages. Translators, including early translators of sacred texts, have helped shape the very l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records con ...

Erik Erikson
Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a German-American developmental psychologist and psychoanalyst known for his theory on psychological development of human beings. He coined the phrase identity crisis. Despite lacking a university degree, Erikson served as a professor at prominent institutions, including Harvard, University of California, Berkeley, and Yale. A '' Review of General Psychology'' survey, published in 2002, ranked Erikson as the 12th most eminent psychologist of the 20th century. Early life Erikson's mother, Karla Abrahamsen, came from a prominent Jewish family in Copenhagen, Denmark. She was married to Jewish stockbroker Valdemar Isidor Salomonsen, but had been estranged from him for several months at the time Erik was conceived. Little is known about Erik's biological father except that he was a non-Jewish Dane. On discovering her pregnancy, Karla fled to Frankfurt am Main in Germany where Erik was born on 15 J ...

Infidelity
Infidelity (synonyms include cheating, straying, adultery, being unfaithful, two-timing, or having an affair) is a violation of a couple's emotional and/or sexual exclusivity that commonly results in feelings of anger, sexual jealousy, and rivalry. What constitutes infidelity depends on expectations within the relationship. In marital relationships, exclusivity is commonly assumed. Infidelity can cause psychological damage, including feelings of rage and betrayal, low sexual and personal confidence, and even post-traumatic stress disorder. People of all genders can experience social consequences if their act of infidelity becomes public, but the form and extent of these consequences can depend on the gender of the unfaithful person. Incidence After the Kinsey Reports came out in the early 1950s, findings suggested that historically and cross-culturally, extramarital sex has been a matter of regulation more than sex before marriage. The Kinsey Reports found that around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulation
A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply ...

Loyalty
Loyalty, in general use, is a devotion and faithfulness to a nation, cause, philosophy, country, group, or person. Philosophers disagree on what can be an object of loyalty, as some argue that loyalty is strictly interpersonal and only another human being can be the object of loyalty. The definition of loyalty in law and political science is the fidelity of an individual to a nation, either one's nation of birth, or one's declared home nation by oath (naturalization). Historical concepts Western world Classical tragedy is often based on a conflict arising from dual loyalty. ''Euthyphro'', one of Plato's early dialogues, is based on the ethical dilemma arising from Euthyphro intending to lay manslaughter charges against his own father, who had caused the death of a slave through negligence. In the Gospel of Matthew 6:24, Jesus states, "No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. Y ...

Wadham College
Wadham College () is one of the constituent colleges of the University of Oxford in the United Kingdom. It is located in the centre of Oxford, at the intersection of Broad Street and Parks Road. Wadham College was founded in 1610 by Dorothy Wadham, according to the will of her late husband Nicholas Wadham, a member of an ancient Devon and Somerset family.

Rankism
Rankism is "abusive, discriminatory, and/or exploitative behavior towards people because of their rank in a particular hierarchy". Rank-based abuse underlies many other phenomena such as bullying, racism, hazing, ageism, sexism, ableism, mentalism, anti-semitism, homophobia and transphobia. The term "rankism" was popularized by physicist, educator, and citizen diplomat Robert W. Fuller. Characteristics Rankism can take many forms, including * exploiting one's position within a hierarchy to secure unwarranted advantages and benefits (e.g. massive corporate bonuses); * abusing a position of power (e.g., abusive parent or priest, corrupt CEO, bully boss, prisoner abuse); * using rank as a shield to get away with insulting or humiliating others with impunity; * using rank to maintain a position of power long after it can be justified; * exporting the rank achieved in one sphere of activity to claim superior value as a person; * exploiting rank that is illegitimately ...

Monasticism
Monasticism (from Ancient Greek , , from , , 'alone'), also referred to as monachism, or monkhood, is a religious way of life in which one renounces worldly pursuits to devote oneself fully to spiritual work. Monastic life plays an important role in many Christian churches, especially in the Catholic and Orthodox traditions as well as in other faiths such as Buddhism, Hinduism and Jainism. In other religions monasticism is criticized and not practiced, as in Islam and Zoroastrianism, or plays a marginal role, as in modern Judaism. Many monastics live in abbeys, convents, monasteries or priories to separate themselves from the secular world, unless they are in mendicant or missionary orders. Buddhism The Sangha or community of ordained Buddhist bhikkhus ("beggar" or "one who lives by alms".) and original bhikkhunis (nuns) was founded by Gautama Buddha during his lifetime over 2500 years ago. This communal monastic lifestyle grew out of the lifestyle of earlier sects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knighthood
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the Christian denomination, church or the country, especially in a military capacity. Knighthood finds origins in the Ancient Greece, Greek ''hippeis'' and ''hoplite'' (ἱππεῖς) and Ancient Rome, Roman ''Equites, eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon Equestrianism, mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect Court (royal), courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in Horses in warfare, battle on horseback. Knighthood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classism
Class discrimination, also known as classism, is prejudice or discrimination on the basis of social class. It includes individual attitudes, behaviors, systems of policies and practices that are set up to benefit the upper class at the expense of the lower class. Social class refers to the grouping of individuals in a hierarchy based on wealth, income, education, occupation, and social network. History Class structures existed in a simplified form in pre-agricultural societies, but it has evolved into a more complex and established structure following the establishment of permanent agriculture-based civilizations with a food surplus. Classism started to be practiced around the 18th century. Segregation into classes was accomplished through observable traits (such as race or profession) that were accorded varying status and privileges. Feudal classification systems might include merchant, serf, peasant, warrior, priestly, and noble classes. Rankings were far from invariant w ...
