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 , 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". In moral philosophy In moral philosophy, fidelity refers to a person who keeps agreements. Strong fidelity refers to a person who keeps agreements even if not mutually beneficial to the other person. 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 ...

4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga Empire, Shunga would add a horizontal line on top of the digit, and the Northern Satraps, Kshatrapa and Pallava dynasty, Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, endi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hi-fi
High fidelity (hi-fi or, rarely, HiFi) is the high-quality reproduction of sound. It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range. High fidelity contrasts with the lower-quality " lo-fi" sound produced by inexpensive audio equipment, AM radio, or the inferior quality of sound reproduction that can be heard in recordings made until the late 1940s. History Bell Laboratories began experimenting with various recording techniques in the early 1930s. Performances by Leopold Stokowski and the Philadelphia Orchestra were recorded in 1931 and 1932 using telephone lines between the Academy of Music in Philadelphia and the Bell labs in New Jersey. Some multitrack recordings were made on optical sound film, which led to new advances used primarily by MGM (as early as 1937) and Twentieth Century Fox Film Corporation (as ...

Monasticism
Monasticism (; ), also called monachism or monkhood, is a religion, religious way of life in which one renounces world (theology), worldly pursuits to devote oneself fully to spiritual activities. Monastic life plays an important role in many Christianity, Christian churches, especially in the Catholicism, Catholic, Eastern Orthodox Church, Orthodox and Anglican traditions as well as in other faiths such as Buddhist monasticism, Buddhism, Hinduism, and Jain monasticism, Jainism. In other religions, monasticism is generally criticized and not practiced, as in Islam and Zoroastrianism, or plays a marginal role, as in modern Nazirite, Judaism. Many monastics live in abbeys, convents, monastery, 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 (Pali ''bhikkhu'', like Sanskrit ''bhikṣu'', means 'mendicant; one who lives by dāna, alms'), and orig ...

Knighthood
A knight is a person granted an honorary title of a 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. The concept of a knighthood may have been inspired by the ancient Greek ''hippeis'' (ἱππεῖς) and Roman ''equites''. In the Early Middle Ages in Western Christian Europe, knighthoods were conferred upon mounted warriors. During the High Middle Ages, a knighthood was considered a class of petty 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. In the Middle Ages, a knighthood was closely linked with horsemanship (and especially the joust) from its origins ...

Infidelity
Infidelity (synonyms include non-consensual non-monogamy, cheating, straying, adultery, being unfaithful, two-timing, or having an affair) is a violation of a couple's emotional 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, depression, low sexual and personal confidence, and even post-traumatic stress disorder. People of both sexes 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.

Erik Erikson
Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a German-American child psychoanalyst and visual artist known for his theory on psychosocial 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 1902 an ... [...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. Studies show an intersection between class discrimination and racism and sexism. Legislation shows efforts to reduce such intersections and classism at an individual level. 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. Segregation into classes was accomplished through observable traits (such as race or profession) that were accorded varying statuses and privileges. Feudal classification syste ...

Translation
Translation is the communication of the semantics, 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 terminological distinction (which does not exist in every language) between ''translating'' (a written text) and ''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 languages into which they have translated. Becau ...

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 the public, private, and voluntary sector, stakeholders might be required to assess—under law or charter—or want to know whether the programs they are funding, implementing, voting for, receiving or opposing are producing the promised effect. To some degree, program evaluation falls under traditional cost–benefit analysis, concerning fair returns on the outlay of economic and other assets; however, social outcomes can be more complex to assess than market outcomes, and a different skillset is required. Considerations include how much the program costs per participant, program impact, how the program could be improved, whether there are better alternatives, if there are unforeseen consequences, and whether the program goals are appropriate and useful.

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. The general principle for orbital overlap is that, the greater the overlap between orbitals, the greater the bond strength. 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 ...

Simulation
A simulation is an imitative representation of a process or system that could exist in the real world. In this broad sense, simulation can often be used interchangeably with model. Sometimes a clear distinction between the two terms is made, in which 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. Another way to distinguish between the terms is to define simulation as experimentation with the help of a model. This definition includes time-independent simulations. Often, computer simulation, 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 functio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Modelling
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate. 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, systems theor ...
