Haptic communication

These touches communicate a double message since they always involve a play signal, either verbal or nonverbal, which indicates the behavior is not to be taken seriously. These touches can be further classified as affectionate and aggressive. Playful affection: Serve to lighten interaction. The seriousness of the positive message is diminished by the play signal. These touches indicate teasing and are usually mutual. Playful aggression: Like playful affection these touches are used to serve to lighten interaction, however, the play signal indicates aggression. These touches are initiated, rather than mutual.

Full stop

Researchers from Binghamton University performed a small study, published in 2016, on young adults and found that text messages that included sentences ended with full stops—as opposed to those with no terminal punctuation—were perceived as insincere, though they stipulated that their results apply only to this particular medium of communication: "Our sense was, is that because [text messages] were informal and had a chatty kind of feeling to them, that a period may have seemed stuffy, too formal, in that context," said head researcher Cecelia Klin. The study did not find handwritten notes to be affected.

The current series of Canadian banknotes has a tactile feature consisting of raised dots that indicate the denomination, allowing bills to be easily identified by blind or low vision people. It does not use standard braille; rather, the feature uses a system developed in consultation with blind and low vision Canadians after research indicated that braille was not sufficiently robust and that not all potential users read braille. Mexican bank notes, Australian bank notes, Indian rupee notes, Israeli new shekel notes and Russian ruble notes also have special raised symbols to make them identifiable by persons who are blind or low vision.


olfactorysmellsense of smell
The proportion of olfactory epithelium compared to respiratory epithelium (not innervated, or supplied with nerves) gives an indication of the animal's olfactory sensitivity. Humans have about 10 cm2 of olfactory epithelium, whereas some dogs have 170 cm2. A dog's olfactory epithelium is also considerably more densely innervated, with a hundred times more receptors per square centimeter. Molecules of odorants passing through the superior nasal concha of the nasal passages dissolve in the mucus that lines the superior portion of the cavity and are detected by olfactory receptors on the dendrites of the olfactory sensory neurons.

Bell Labs

Bell LaboratoriesBell Telephone LaboratoriesAT&T Bell Laboratories
In 1948, "A Mathematical Theory of Communication", one of the founding works in information theory, was published by Claude Shannon in the Bell System Technical Journal. It built in part on earlier work in the field by Bell researchers Harry Nyquist and Ralph Hartley, but it greatly extended these. Bell Labs also introduced a series of increasingly complex calculators through the decade. Shannon was also the founder of modern cryptography with his 1949 paper Communication Theory of Secrecy Systems. In 1952, William Gardner Pfann revealed the method of zone melting which enabled semiconductor purification and level doping.

An account of the discovery was published in 1802 in an Italian newspaper, but it was largely overlooked by the contemporary scientific community, because Romagnosi seemingly did not belong to this community. An earlier (1735), and often neglected, connection between electricity and magnetism was reported by a Dr. Cookson. The account stated: A tradesman at Wakefield in Yorkshire, having put up a great number of knives and forks in a large box ... and having placed the box in the corner of a large room, there happened a sudden storm of thunder, lightning, &c. ...


photographerphotographicstill photography
A large variety of photographic techniques and media are used in the process of capturing images for photography. These include the camera; stereoscopy; dualphotography; full-spectrum, ultraviolet and infrared media; light field photography; and other imaging techniques. The camera is the image-forming device, and a photographic plate, photographic film or a silicon electronic image sensor is the capture medium. The respective recording medium can be the plate or film itself, or a digital magnetic or electronic memory.


biochemistbiochemicalbiological chemistry
There are more carbohydrates on Earth than any other known type of biomolecule; they are used to store energy and genetic information, as well as play important roles in cell to cell interactions and communications. The simplest type of carbohydrate is a monosaccharide, which among other properties contains carbon, hydrogen, and oxygen, mostly in a ratio of 1:2:1 (generalized formula C n H 2n O n, where n is at least 3). Glucose (C 6 H 12 O 6 ) is one of the most important carbohydrates; others include fructose (C 6 H 12 O 6 ), the sugar commonly associated with the sweet taste of fruits, and deoxyribose (C 5 H 10 O 4 ), a component of DNA.

Communication theory

communicationcommunications theorycommunication theorist
"Communication is a process of expression, interaction, and influence, in which the behavior of humans or other complex organisms expresses psychological mechanisms, states, and traits and, through interaction with the similar expressions of other individuals, produces a range of cognitive, emotional, and behavioral effects.” (Craig, 1999, p. 143) The most commonly described Models of Communication: The Linear Model of communication works in one direction only, a sender encodes some message and sends it through a channel for a receiver to decode. In comparison, the Interactional Model of communication works bidirectional.

Movie theater

A Pew Media survey from 2006 found that the relationship between movies watched at home versus at the movie theater was in a five to one ratio and 75% of respondents said their preferred way of watching a movie was at home, versus 21% who said they preferred to go to a theater. In 2014, it was reported that the practice of releasing a film in theaters and via on-demand steaming on the same day (for selected films) and the rise in popularity of the Netflix streaming service has led to concerns in the movie theater industry.

Meaning (linguistics)

meaninglinguistic meaningmeanings
Saussure instead defers meaning to the sign itself: meaning is ultimately the same thing as the sign, and meaning means that relationship is between signified and signifier. All meaning is both within us and communal, thus cultural. Signs "mean" by reference to our internal lexicon and grammar, and despite there being a matter of convention, so the communal part, signs also, because of the individual's uniqueness, can mean something only to the individual (what red means to one person may not be what red means to another, either in absolute value, or by including what's suggested by the context).

This climate change shifted the cost-benefit ratio of endemic violence between communities, which saw the abandonment of unwalled village communities and the appearance of walled cities, associated with the first civilizations. This "urban revolution" marked the beginning of the accumulation of transferrable surpluses, which helped economies and cities develop. It was associated with the state monopoly of violence, the appearance of a soldier class and endemic warfare, the rapid development of hierarchies, and the appearance of human sacrifice.

intrinsic motivationmotivationalmotives
In some indigenous cultures, collaboration between children and adults in community and household tasks is seen as very important A child from an indigenous community may spend a great deal of their time alongside family and community members doing different tasks and chores that benefit the community. After having seen the benefits of collaboration and work, and also having the opportunity to be included, the child will be intrinsically motivated to participate in similar tasks. In this example, because the adults in the community do not impose the tasks upon the children, the children therefore feel self-motivated and a desire to participate and learn through the task.


reasoningratiocinationhuman reason
More generally, reason in the strict sense requires the ability to create and manipulate a system of symbols, as well as indices and icons, according to Charles Sanders Peirce, the symbols having only a nominal, though habitual, connection to either smoke or fire. One example of such a system of artificial symbols and signs is language. The connection of reason to symbolic thinking has been expressed in different ways by philosophers. Thomas Hobbes described the creation of "Markes, or Notes of remembrance" (Leviathan Ch. 4) as speech. He used the word speech as an English version of the Greek word logos so that speech did not need to be communicated.

The role of the system as an intelligence gathering apparatus is well documented, and the service was (later) called angariae, a term that in time came to indicate a tax system. The Old Testament (Esther, VIII) makes mention of this system: Ahasuerus, king of Medes, used couriers for communicating his decisions. The Persian system worked using stations (called Chapar-Khaneh), whence the message carrier (called Chapar) would ride to the next post, whereupon he would swap his horse with a fresh one for maximum performance and delivery speed.

Achaemenid Empire

AchaemenidPersianPersian Empire
Even though the Achaemenids had extensive contacts with the Greeks and vice versa, and had conquered many of the Greek-speaking areas both in Europe and Asia Minor during different periods of the empire, the native Old Iranian sources provide no indication of Greek linguistic evidence. However, there is plenty of evidence (in addition to the accounts of Herodotus) that Greeks, apart from being deployed and employed in the core regions of the empire, also evidently lived and worked in the heartland of the Achaemenid Empire, namely Iran.

Shannon–Weaver model

Shannon-Weaver modelShannon and Weaver's model
The Shannon–Weaver model of communication has been called the "mother of all models." Social Scientists use the term to refer to an integrated model of the concepts of information source, message, transmitter, signal, channel, noise, receiver, information destination, probability of error, encoding, decoding, information rate, channel capacity, etc. However, some consider the name to be misleading, asserting that the most significant ideas were developed by Shannon alone. In 1948 Claude Elwood Shannon published A Mathematical Theory of Communication article in two parts in the July and October numbers of the Bell System Technical Journal.

Chapar Khaneh

postal systemChapar-KhanehChapar
The system was created by Cyrus the Great, the founder of the Persian Empire, and later developed by Darius the Great, as the royal method of communication throughout the empire. Each "Chapar Khaneh" was a station mainly located along the Royal Road, a 2500 km ancient highway, which stretched from Sardis to Susa, connecting most of the major cities of the empire. Herodotus' description of the "Royal Road" and the various "Chapar Khanehs" along it is as follows: In Armenia the resting-places are 15 in number, and the distance is 56½ parasangs. There is one place where a guard is posted. Four large streams intersect this district, all of which have to be crossed by means of boats.

Digital data

digitaldigital informationdigitally
Machine communications typically use special synchronization sequences. Language: All digital communications require a formal language, which in this context consists of all the information that the sender and receiver of the digital communication must both possess, in advance, in order for the communication to be successful. Languages are generally arbitrary and specify the meaning to be assigned to particular symbol sequences, the allowed range of values, methods to be used for synchronization, etc. Errors: Disturbances (noise) in analog communications invariably introduce some, generally small deviation or error between the intended and actual communication.


A secondary meaning within the UK broadcast engineering community is as a synonym for broadcast transmitter. Communication source. Director telephone system. Panel switch. Register signaling.


way stations
The Angarium (Latin; from Greek Ἀγγαρήιον angareion) was the institution of the royal mounted couriers in ancient Persia. The messengers, called angaros, alternated in stations that had a day's ride distance along the Royal Road. The riders were exclusively in the service of the Great King and the network allowed for messages to be transported from Susa to Sardis (2699 km) in nine days; the journey took ninety days on foot.


philosophicalphilosopherhistory of philosophy
The philosophy of film analyzes films and filmmakers for their philosophical content and explores film (images, cinema, etc.) as a medium for philosophical reflection and expression. Political philosophy is the study of government and the relationship of individuals (or families and clans) to communities including the state. It includes questions about justice, law, property and the rights and obligations of the citizen. Politics and ethics are traditionally linked subjects, as both discuss the question of how people should live together. Other branches of value theory: Many academic disciplines generated philosophical inquiry.

Spoken word

spoken-wordspoken word artistspoken word poetry
Drumming for accompaniment is not to be confused with performances of the "talking drum", which is a literature of its own, since it is a distinct method of communication that depends on conveying meaning through non-musical grammatical, tonal and rhythmic rules imitating speech. Although, they could be included in performances of the griots. In ancient Greece, the spoken word was the most trusted repository for the best of their thought, and inducements would be offered to men (such as the rhapsodes) who set themselves the task of developing minds capable of retaining and voices capable of communicating the treasures of their culture.

Roman Empire

Claudius tried to limit the use of Greek, and on occasion revoked the citizenship of those who lacked Latin, but even in the Senate he drew on his own bilingualism in communicating with Greek-speaking ambassadors. Suetonius quotes him as referring to "our two languages". In the Eastern empire, laws and official documents were regularly translated into Greek from Latin. The everyday interpenetration of the two languages is indicated by bilingual inscriptions, which sometimes even switch back and forth between Greek and Latin.
