Bachelor’s degree

A bachelor’s degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to seven years (depending on institution and academic discipline). The two most common bachelor’s degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, some bachelor’s degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor’s degree is a prerequisite for further courses such as a master’s or a doctorate.

In countries with qualifications frameworks, bachelor’s degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor’s degrees are considered separately), although some qualifications titled bachelor’s degrees may be at other levels (e.g., MBBS) and some qualifications with non-bachelor’s titles may be classified as bachelor’s degrees (e.g. the Scottish MA and Canadian MD).



A bank is a financial institution that accepts deposits from the public and creates a demand deposit while simultaneously making loans. Lending activities can be directly performed by the bank or indirectly through capital markets.

Because banks play an important role in financial stability and the economy of a country, most jurisdictions exercise a high degree of regulation over banks. Most countries have institutionalized a system known as fractional reserve banking, under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, the Basel Accords.

Banking in its modern sense evolved in the fourteenth century in the prosperous cities of Renaissance Italy but in many ways functioned as a continuation of ideas and concepts of credit and lending that had their roots in the ancient world. In the history of banking, a number of banking dynasties — notably, the Medicis, the Fuggers, the Welsers, the Berenbergs, and the Rothschilds — have played a central role over many centuries. The oldest existing retail bank is Banca Monte dei Paschi di Siena (founded in 1472), while the oldest existing merchant bank is Berenberg Bank (founded in 1590).



A bar is a long raised narrow table or bench designed for dispensing beer or other alcoholic drinks. They were originally chest high, and a bar, often brass, ran the length of the table, just above floor height, for customers to rest a foot on, which gave the table its name. Over many years, heights of bars were lowered, and high stools added, and the brass bar remains today. The name bar became identified with the business, (also known as a saloon or a tavern or sometimes as a pub or club, referring to the actual establishment, as in pub bar or club bar etc.) is a retail business establishment that serves alcoholic beverages, such as beer, wine, liquor, cocktails, and other beverages such as mineral water and soft drinks. Bars often also sell snack foods such as crisps (also referred to as potato chips) or peanuts, for consumption on their premises. Some types of bars, such as pubs, may also serve food from a restaurant menu. The term “bar” also refers to the countertop and area where drinks are served. The term “bar” derives from the metal or wooden bar (barrier) that is often located along the length of the “bar”.



Beauty is the ascription of a property or characteristic to an animal, idea, object, person or place that provides a perceptual experience of pleasure or satisfaction. Beauty is studied as part of aesthetics, culture, social psychology, philosophy and sociology. An “ideal beauty” is an entity which is admired, or possesses features widely attributed to beauty in a particular culture, for perfection. Ugliness is the opposite of beauty.



Behavior (American English) or behaviour (British English; see spelling differences) is the actions and mannerisms made by individuals, organisms, systems or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.

Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector.

Behavioural genetics

Behavioural genetics, also referred to as behaviour genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behaviour. While the name “behavioural genetics” connotes a focus on genetic influences, the field broadly investigates genetic and environmental influences, using research designs that allow removal of the confounding of genes and environment. Behavioural genetics was founded as a scientific discipline by Francis Galton in the late 19th century, only to be discredited through association with eugenics movements before and during World War II. In the latter half of the 20th century, the field saw renewed prominence with research on inheritance of behaviour and mental illness in humans (typically using twin and family studies), as well as research on genetically informative model organisms through selective breeding and crosses. In the late 20th and early 21st centuries, technological advances in molecular genetics made it possible to measure and modify the genome directly. This led to major advances in model organism research (e.g., knockout mice) and in human studies (e.g., genome-wide association studies), leading to new scientific discoveries.


Behavioral script

In the behaviorism approach to psychology, behavioral scripts are a sequence of expected behaviors for a given situation. Scripts include default standards for the actors, props, setting, and sequence of events that are expected to occur in a particular situation. The classic script example involves an individual dining at a restaurant. This script has several components: props including tables, menus, food, and money, as well as roles including customers, servers, chefs, and a cashier. The sequence of expected events for this script begins with a hungry customer entering the restaurant, ordering, eating, paying and then ends with the customer exiting. People continually follow scripts which are acquired through habit, practice and simple routine. Following a script can be useful because it could help to save the time and mental effort of deciding on appropriate behavior each time a situation is encountered.

Behaviorism is a systematic approach to understanding the behavior of humans and other animals. It assumes that behavior is either a reflex evoked by the pairing of certain antecedent stimuli in the environment, or a consequence of that individual’s history, including especially reinforcement and punishment contingencies, together with the individual’s current motivational state and controlling stimuli. Although behaviorists generally accept the important role of heredity in determining behavior, they focus primarily on environmental events.

It combines elements of philosophy, methodology, and theory. Behaviorism emerged in the early 1900s as a reaction to depth psychology and other traditional forms of psychology, which often had difficulty making predictions that could be tested experimentally, but derived from earlier research in the late nineteenth century, such as when Edward Thorndike pioneered the law of effect, a procedure that involved the use of consequences to strengthen or weaken behavior.

A belief is an attitude that something is the case, or that some proposition about the world is true. In epistemology, philosophers use the term “belief” to refer to attitudes about the world which can be either true or false. To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition “snow is white”. However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking “snow is white”), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert “snow is white”).



Biochemistry or biological chemistry, is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells, in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function. Biochemistry is closely related to molecular biology which is the study of the molecular mechanisms of biological phenomena.

Much of biochemistry deals with the structures, functions, and interactions of biological macromolecules, such as proteins, nucleic acids, carbohydrates, and lipids. They provide the structure of cells and perform many of the functions associated with life. The chemistry of the cell also depends upon the reactions of small molecules and ions. These can be inorganic (for example, water and metal ions) or organic (for example, the amino acids, which are used to synthesize proteins). The mechanisms used by cells to harness energy from their environment via chemical reactions are known as metabolism. The findings of biochemistry are applied primarily in medicine, nutrition and agriculture. In medicine, biochemists investigate the causes and cures of diseases. Nutrition studies how to maintain health and wellness and also the effects of nutritional deficiencies. In agriculture, biochemists investigate soil and fertilizers. Improving crop cultivation, crop storage, and pest control are also goals.


Biological determinism

Biological determinism, also known as genetic determinism, is the belief that human behaviour is directly controlled by an individual’s genes or some component of their physiology, generally at the expense of the role of the environment, whether in embryonic development or in learning. Genetic reductionism is a similar concept, but it is distinct from genetic determinism in that the former refers to the level of understanding, while the latter refers to the supposedly causal role of genes. Biological determinism has been associated with movements in science and society including eugenics, scientific racism, and the debates around the heritability of IQ, the basis of sexual orientation, and sociobiology.



Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis.


Black propaganda

Black propaganda is a form of propaganda intended to create the impression that it was created by those it is supposed to discredit. Black propaganda contrasts with grey propaganda, which does not identify its source, and white propaganda, which does not disguise its origins at all. It is typically used to vilify or embarrass the enemy through misrepresentation.


Body art

Body art is art made on, with, or consisting of, the human body. The most common forms of body art are tattoos and body piercings. Other types include scarification, branding, subdermal implants, scalpelling, shaping (for example tight-lacing of corsets), full body tattoo and body painting.

Body art is also a sub-category of performance art, in which artists use or abuse their own body to make their particular statements. More extreme body art can involve mutilation or pushing the body to its physical limits.

In more recent times, the body has become a subject of much broader discussion and treatment than can be reduced to body art in its common understanding. Important strategies that question the human body are: implants, body in symbiosis with the new technologies, virtual bodies, among others.


Body language

Body language is a type of nonverbal communication in which physical behaviors, as opposed to words, are used to express or convey the information. Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space. Body language exists in both animals and humans, but this article focuses on interpretations of human body language. It is also known as kinesics.

Although body language is an important part of communication, most of it happens without conscious awareness.

Body “language” must not be confused with sign language, as sign languages are languages and have their own complex grammar systems, as well as being able to exhibit the fundamental properties that exist in all languages. Body language, on the other hand, does not have a grammar system and must be interpreted broadly, instead of having an absolute meaning corresponding with a certain movement, so it is not a language, and is simply termed as a “language” due to popular culture.



book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is codex (in the plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its immediate predecessor, the scroll. A single sheet in a codex is a leaf, and each side of a leaf is a page.



brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate’s body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.


Brain Gym International

Brain Gym is a proprietary brain training and body movement programme. It is widely considered to be pseudoscience.

“Brain Gym International” is the trade name of the Educational Kinesiology Foundation, a California nonprofit corporation that was incorporated in 1987 and that received its IRS ruling as a nonprofit in 1992. “Brain Gym” is a registered trademark owned by the company.



Business is the activity of making one’s living or making money by producing or buying and selling products (such as goods and services). Simply put, it is “any activity or enterprise entered into for profit.”

Having a business name does not separate the business entity from the owner, which means that the owner of the business is responsible and liable for debts incurred by the business. If the business acquires debts, the creditors can go after the owner’s personal possessions. A business structure does not allow for corporate tax rates. The proprietor is personally taxed on all income from the business.

The term is also often used colloquially (but not by lawyers or by public officials) to refer to a company. A company, on the other hand, is a separate legal entity and provides for limited liability, as well as corporate tax rates. A company structure is more complicated and expensive to set up, but offers more protection and benefits for the owner.
