A taboo is an implicit prohibition on something (usually against an utterance or behavior) based on a cultural sense that it is excessively repulsive or, perhaps, too sacred for ordinary people. Such prohibitions are present in virtually all societies. On a comparative basis, taboos, for example related to food items, seem to make no sense at all, as what may be declared unfit for one group by custom or religion may be perfectly acceptable to another.
Taboos are often meant to protect the human individual, but there are numerous other reasons for their existence. An ecological or medical background is apparent in many, including some that are seen as religious or spiritual in origin. Taboos can help use a resource more efficiently, but when applied to only a subsection of the community they can also serve to suppress said subsection of the community. A taboo acknowledged by a particular group or tribe as part of their ways aids in the cohesion of the group, helps that particular group to stand out and maintain its identity in the face of others and therefore creates a feeling of “belonging”.
A talent community is a mechanism that employers use to keep active pipelines of talent for future recruitment. Talent pipelines consist of potential employees who are interested in working at a given employer, but are not ready to apply. This group is engaged with on a frequent basis so that when the potential employees are ready to seek a new job, they have a relationship with the company.
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). Taste is the perception produced or stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with olfaction and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food and other substances. Humans have taste receptors on taste buds and other areas including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste.
In sociology, taste is an individual’s personal, cultural and aesthetic patterns of choice and preference. Taste is drawing distinctions between things such as styles, manners, consumer goods, and works of art and relating to these. Social inquiry of taste is about the human ability to judge what is beautiful, good, and proper.
Social and cultural phenomena concerning taste are closely associated to social relations and dynamics between people. The concept of social taste is therefore rarely separated from its accompanying sociological concepts. An understanding of taste as something that is expressed in actions between people helps to perceive many social phenomena that would otherwise be inconceivable.
Aesthetic preferences and attendance to various cultural events are associated with education and social origin. Different socioeconomic groups are likely to have different tastes. Social class is one of the prominent factors structuring taste.
A taxicab, also known as a taxi or a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from public transport where the pick-up and drop-off locations are decided by the service provider, not by the customers, although demand responsive transport and share taxis provide a hybrid bus/taxi mode.
A teacher (also called a schoolteacher or formally, an educator) is a person who helps students to acquire knowledge, competence or virtue.
Informally the role of teacher may be taken on by anyone (e.g. when showing a colleague how to perform a specific task). In some countries, teaching young people of school age may be carried out in an informal setting, such as within the family (homeschooling), rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching (e.g. youth worker, pastor).
In most countries, formal teaching of students is usually carried out by paid professional teachers. This article focuses on those who are employed, as their main role, to teach others in a formal education context, such as at a school or other place of initial formal education or training.
A team is a [group (disambiguation)|group]] of individuals (human or non-human) working together to achieve their goal.
As defined by Professor Leigh Thompson of the Kellogg School of Management, “[a] team is a group of people who are interdependent with respect to information, resources, knowledge and skills and who seek to combine their efforts to achieve a common goal”.
A group does not necessarily constitute a team. Teams normally have members with complementary skills and generate synergy through a coordinated effort which allows each member to maximize their strengths and minimize their weaknesses. Naresh Jain (2009) claims:
Team members need to learn how to help one another, help other team members realize their true potential, and create an environment that allows everyone to go beyond their limitations.
A team sport includes any sport where individuals are organized into opposing teams which compete to win. Team members act together towards a shared objective. This can be done in a number of ways such as outscoring the opposing team. Team members set goals, make decisions, communicate, manage conflict, and solve problems in a supportive, trusting atmosphere in order to accomplish their objectives. Examples are basketball, volleyball, rugby, water polo, handball, lacrosse, cricket, baseball, and the various forms of association football and hockey.
A technician is a worker in a field of technology who is proficient in the relevant skill and technique, with a relatively practical understanding of the theoretical principles.
The term technician covers many different specialisations. These include:
School laboratory technician
In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes. Some researchers point to association of temperament with formal dynamical features of behavior, such as energetic aspects, plasticity, sensitivity to specific reinforcers and emotionality. Temperament traits (such as Neuroticism, Sociability, Impulsivity, etc.) remain its distinct patterns in behavior throughout adulthood but they are most noticeable and most studied in children. Babies are typically described by temperament, but longitudinal research in the 1920s began to establish temperament as something which is stable across the lifespan.
Theatre or theater is a collaborative form of performing art that uses live performers, typically actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word “theatre” as derived from the Ancient Greek θέατρον (théatron, “a place for viewing”), itself from θεάομαι (theáomai, “to see”, “to watch”, “to observe”).
Theory of multiple intelligences
The theory of multiple intelligences proposes the differentiation of human intelligence into specific “modalities of intelligence”, rather than defining intelligence as a single, general ability. The theory has been criticized by mainstream psychology for its lack of empirical evidence, and its dependence on subjective judgement.
Thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux. The details of how temperature receptors work are still being investigated. Ciliopathy is associated with decreased ability to sense heat, thus cilia may aid in the process. Transient receptor potential channels (TRP channels) are believed to play a role in many species in sensation of hot, cold, and pain. Vertebrates have at least two types of sensor: those that detect heat and those that detect cold.
A particularly specialized form of thermoception is used by Crotalinae (pit viper) and Boidae (boa) snakes, which can effectively see the infrared radiation emitted by hot objects. The snakes’ face has a pair of holes, or pits, lined with temperature sensors. The sensors indirectly detect infrared radiation by its heating effect on the skin inside the pit. They can work out which part of the pit is hottest, and therefore the direction of the heat source, which could be a warm-blooded prey animal. By combining information from both pits, the snake can also estimate the distance of the object.
Thought encompasses an “aim-oriented flow of ideas and associations that can lead to a reality-oriented conclusion”. Although thinking is an activity of an existential value for humans, there is still no consensus as to how it is adequately defined or understood.
Tickling is the act of touching a part of a body in a way that causes involuntary twitching movements or laughter. The word About this sound”tickle” (help·info) evolved from the Middle English tikelen, perhaps frequentative of ticken, to touch lightly.
In 1897, psychologists G. Stanley Hall and Arthur Allin described a “tickle” as two different types of phenomena. One type is caused by very light movement across the skin. This type of tickle, called a knismesis, generally does not produce laughter and is sometimes accompanied by an itching sensation.
Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future. Time is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions.
The study of time perception is a field within psychology, cognitive linguistics and neuroscience that refers to the subjective experience, or sense, of time, which is measured by someone’s own perception of the duration of the indefinite and unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Though directly experiencing or understanding another person’s perception of time is not possible, such a perception can be objectively studied and inferred through a number of scientific experiments. Some temporal illusions help to expose the underlying neural mechanisms of time perception.
Pioneering work, emphasizing species-specific differences, was conducted by Karl Ernst von Baer.
Timeline of historic inventions
The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and their inventors, where known.
Note: Dates for inventions are often controversial. Sometimes inventions are invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.
A proportion of all discoveries within the United States made during the 20th (after 1943) and 21st centuries were made within skunk work enterprises.
Timeline of scientific discoveries
The timeline below shows the date of publication of possible major scientific breakthroughs, theories and discoveries, along with the discoverer. For the purposes of this article, we do not regard mere speculation as discovery, although imperfect reasoned arguments, arguments based on elegance/simplicity, and numerically/experimentally verified conjectures qualify (as otherwise no scientific discovery before the late 19th century would count). We begin our timeline at the Bronze Age, as it is difficult to estimate the timeline before this point, such as of the discovery of counting, natural numbers and arithmetic.
A tool is an object that can extend an individual’s ability to modify features of the surrounding environment. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. The set of tools required to perform different tasks that are part of the same activity is called gear or equipment.
While one may apply the term tool loosely to many things that are means to an end (e.g., a fork), strictly speaking an object is a tool only if, besides being constructed to be held, it is also made of a material that allows its user to apply to it various degrees of force. If repeated use wears part of the tool down (like a knife blade), it may be possible to restore it; if it wears the tool out or breaks it, the tool must be replaced. Thus tool falls under the taxonomic category implement, and is on the same taxonomic rank as instrument, utensil, device, or ware.
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go “beyond the common perception of tourism as being limited to holiday activity only”, as people “traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes”.
A tourist attraction is a place of interest where tourists visit, typically for its inherent or an exhibited natural or cultural value, historical significance, natural or built beauty, offering leisure and amusement.
Places of natural beauty such as beaches, tropical island resorts, national parks, mountains, deserts and forests, are examples of traditional tourist attractions which people may visit. Cultural tourist attractions can include historical places, monuments, ancient temples, zoos, aquaria, museums and art galleries, botanical gardens, buildings and structures (such as forts, castles, libraries, former prisons, skyscrapers, bridges), theme parks and carnivals, living history museums, public art (sculptures, statues, murals), ethnic enclave communities, historic trains and cultural events. Factory tours, industrial heritage, creative art and crafts workshops are the object of cultural niches like industrial tourism and creative tourism. Many tourist attractions are also landmarks. But sports events such as a soccer game, Formula 1 race or sailing regatta can also attract tourists.
Tourists’ expectations when visiting a particular place are related to several features of the chosen destination: culture, architecture, gastronomy, infrastructure, landscape, events, shopping, etc. These features attract people to the destination and contribute to the overall experience of the trip. The ultimate primary purpose of attractions is to attract the customer’s attention so that they can come to a specific location and explore the various attractions on vacation. In the travel and tourism industry, attractions therefore play a particularly important role as this attracts tourists from all over the world.
Trade involves the transfer of goods or services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market.
A tradition is a belief or behavior (folk custom) passed down within a group or society with symbolic meaning or special significance with origins in the past. A component of folklore, common examples include holidays or impractical but socially meaningful clothes (like lawyers’ wigs or military officers’ spurs), but the idea has also been applied to social norms such as greetings. Traditions can persist and evolve for thousands of years—the word tradition itself derives from the Latin tradere literally meaning to transmit, to hand over, to give for safekeeping. While it is commonly assumed that traditions have an ancient history, many traditions have been invented on purpose, whether that be political or cultural, over short periods of time. Various academic disciplines also use the word in a variety of ways.
A train driver, engine driver or locomotive driver, commonly known as an engineer in the United States and Canada, and also as a locomotive handler, locomotive operator, train operator, or motorman, is a person who drives a train. The driver is in charge of, and responsible for operating the engine, as well as the mechanical operation of the train, train speed, and all train handling. In American English, a hostler moves engines around train yards, but does not take them out on the normal tracks; the British English equivalent is a shunter.
Translation is the communication of the meaning of a source-language text by means of an equivalent 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 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.
Because of the laboriousness of the translation process, since the 1940s efforts have been made, with varying degrees of success, to automate translation or to mechanically aid the human translator. More recently, the rise of the Internet has fostered a world-wide market for translation services and has facilitated “language localisation”.
Transport (commonly used in the U.K.), or transportation (used in the U.S.), is the movement of humans, animals and goods from one location to another. In other words, the action of transport is defined as a particular movement of an organism or thing from a point A (a place in space) to a point B. Modes of transport include air, land (rail and road), water, cable, pipeline and space. The field can be divided into infrastructure, vehicles and operations. Transport enables trade between people, which is essential for the development of civilizations.
Transport infrastructure consists of the fixed installations, including roads, railways, airways, waterways, canals and pipelines and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance.
Vehicles traveling on these networks may include automobiles, bicycles, buses, trains, trucks, helicopters, watercraft, spacecraft and aircraft.
Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, ship or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements, as in the case of tourism.
A triathlon is an endurance multisport race consisting of swimming, cycling, and running over various distances. Triathletes compete for fastest overall completion time, racing each segment sequentially with the time transitioning between the disciplines included. The word is of Greek origin, from τρεῖς or treis (three) and ἆθλος or athlos (competition).
A truck driver (commonly referred to as a trucker, teamster or driver in the United States and Canada; a truckie in Australia and New Zealand; a lorry driver, or driver in Ireland, the United Kingdom, India, Nepal and Pakistan) is a person who earns a living as the driver of a truck (usually a semi truck, box truck or dump truck).
Trust (social science)
Trust exists in interpersonal relationships. Humans have a natural disposition to trust and to judge trustworthiness. This can be traced to the neurobiological structure and activity of a human brain. Some studies indicate that trust can be altered e.g. by the application of oxytocin.
In a social context, trust has several connotations. Definitions of trust typically refer to situations characterized by the following aspects: one party (trustor) is willing to rely on the actions of another party (trustee), and the situation is typically directed to the future. In addition, the trustor (voluntarily or forcedly) abandons control over the actions performed by the trustee. As a consequence, the trustor is uncertain about the outcome of the other’s actions; the trustor can only develop and evaluate expectations. Such expectations are formed with a view to the motivations of the trustee, dependent on their characteristics, the situation, and their interaction. The uncertainty stems from the risk of failure or harm to the trustor if the trustee does not behave as desired.
When it comes to the relationship between people and technology, the attribution of trust is a matter of dispute. The intentional stance demonstrates that trust can be validly attributed to human relationships with complex technologies. One of the key current challenges in the social sciences is to rethink how the rapid progress of technology has impacted constructs such as trust. This is especially true for information technology that dramatically alters causation in social systems.
