Fidelity Management
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 in the ...

4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically 3, three. The sum of the first four prime numbers 2, two + 3, three + 5, five + 7, seven is the only sum of four consecutive prime numbers that yields an Parity (mathematics), odd prime number, 17 (number), seventeen, which is the fourth super-prime.

Rock Music
Rock music is a broad genre of popular music that originated as " rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles in the mid-1960s and later, particularly in the United States and United Kingdom.W. E. Studwell and D. F. Lonergan, ''The Classic Rock and Roll Reader: Rock Music from its Beginnings to the mid-1970s'' (Abingdon: Routledge, 1999), p.xi It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical, and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a time signature using a verse–chorus form, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 acquired or ...

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 of wander ... [...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 church or the country, especially in a military capacity. Knighthood finds origins in the Greek ''hippeis'' and '' hoplite'' (ἱππεῖς) and Roman '' eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon 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 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 battle on horseback. Knighthood in the Middle Ages was closely linked with horsemanship (and especially the joust) from its origins in th ...

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 June 19 ...

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 wit ...

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] |
Program Evaluation
Program evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency. In both the public and private sectors, stakeholders often want to know whether the programs they are funding, implementing, voting for, receiving or objecting to are producing the intended effect. While ''program evaluation'' first focuses around this definition, important considerations often include how much the program costs per participant, how the program could be improved, whether the program is worthwhile, whether there are better alternatives, if there are ''unintended'' outcomes, and whether the program goals are appropriate and useful. Evaluators help to answer these questions, but the best way to answer the questions is for the evaluation to be a joint project between evaluators and stakeholders. The process of evaluation is considered to be a relatively recent pheno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Overlap
In chemical bonds, an orbital overlap is the concentration of orbitals on adjacent atoms in the same regions of space. Orbital overlap can lead to bond formation. Linus Pauling explained the importance of orbital overlap in the molecular bond angles observed through experimentation; it is the basis for orbital hybridization. As ''s'' orbitals are spherical (and have no directionality) and ''p'' orbitals are oriented 90° to each other, a theory was needed to explain why molecules such as methane (CH4) had observed bond angles of 109.5°. Pauling proposed that s and p orbitals on the carbon atom can combine to form hybrids (sp3 in the case of methane) which are directed toward the hydrogen atoms. The carbon hybrid orbitals have greater overlap with the hydrogen orbitals, and can therefore form stronger C–H bonds.Pauling, Linus. (1960). ''The Nature Of The Chemical Bond''. Cornell University Press. A quantitative measure of the overlap of two atomic orbitals ΨA and ΨB o ... [...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 Conceptual model, 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 computer simulation, 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 bu ...

Scientific Modelling
Scientific modelling is a scientific activity, the aim of which is to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate by referencing it to existing and usually commonly accepted knowledge. It requires selecting and identifying relevant aspects of a situation in the real world and then developing a model to replicate a system with those features. Different types of models may be used for different purposes, such as conceptual models to better understand, operational models to operationalize, mathematical models to quantify, computational models to simulate, and graphical models to visualize the subject. Modelling is an essential and inseparable part of many scientific disciplines, each of which has its own ideas about specific types of modelling. The following was said by John von Neumann. There is also an increasing attention to scientific modelling in fields such as science education, philosophy of science, ...
