Sympathy

Sympathy (from the Greek words syn "together" and pathos "feeling" which means "fellow-feeling") is the perception, understanding, and reaction to the distress or need of another human being. This empathic concern is driven by a switch in viewpoint, from a personal perspective to the perspective of another group or individual who is in need. Empathy and sympathy are often used interchangeably. Sympathy is a feeling, but the two terms have distinct origins and meanings. Merriam Webster defines empathy as "the feeling that you understand and share another person's experiences and emotions : the ability to share someone else's feelings." Their definition of sympathy is "the feeling that you care about and are sorry about someone else's trouble, grief, misfortune, etc. : a feeling of support for something : a state in which different people share the same interests, opinions, goals, etc." See professor Paul Bloom on empathy.

Causes

In order to get an experience of sympathy there are specific conditions that need to occur. These include: attention to a subject, believing that a person/group is in a state of need, and the specific characteristics of a given situation. An individual must first give his or her attention to a person/group. Distractions severely limit the ability to produce strong affective responses. Without distractions, people are able to attend to and respond to a variety of emotional subjects and experiences. Attention facilitates the experience of sympathy, and without giving undivided attention to many situations sympathy cannot be experienced.

Support and resistance

In technical analysis, support and resistance is a concept that the movement of the price of a security will tend to stop and reverse at certain predetermined price levels. These levels are denoted by multiple touches of price without a breakthrough of the level.

Support versus resistance

A support level is a level where the price tends to find support as it falls. This means the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue falling until meeting another support level.

A resistance level is the opposite of a support level. It is where the price tends to find resistance as it rises. This means the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue rising until meeting another resistance level.

Structure (mathematical logic)

In universal algebra and in model theory, a structure consists of a set along with a collection of finitary operations, and relations that are defined on it.

Universal algebra studies structures that generalize the algebraic structures such as groups, rings, fields and vector spaces. The term universal algebra is used for structures with no relation symbols.

Model theory has a different scope that encompasses more arbitrary theories, including foundational structures such as models of set theory. From the model-theoretic point of view, structures are the objects used to define the semantics of first-order logic. For a given theory in model theory, a structure is called a model, if it satisfies the defining axioms of that theory, although it is sometimes disambiguated as a semantic model when one discusses the notion in the more general setting of mathematical models. Logicians sometimes refer to structures as interpretations.

In database theory, structures with no functions are studied as models for relational databases, in the form of relational models.

Structure (category theory)

In mathematics, progress often consists of recognising the same structure in different contexts - so that one method exploiting it has multiple applications. In fact this is a normal way of proceeding; in the absence of recognisable structure (which might be hidden) problems tend to fall into the combinatorics classification of matters requiring special arguments.

In category theory structure is discussed implicitly - as opposed to the explicit discussion typical with the many algebraic structures. Starting with a given class of algebraic structure, such as groups, one can build the category in which the objects are groups and the morphisms are group homomorphisms: that is, of structures on one type, and mappings respecting that structure. Starting with a category C given abstractly, the challenge is to infer what structure it is on the objects that the morphisms 'preserve'.

The term structure was much used in connection with the Bourbaki group's approach. There is even a definition. Structure must definitely include topological space as well as the standard abstract algebra notions. Structure in this sense is probably commensurate with the idea of concrete category that can be presented in a definite way - the topological case means that infinitary operations will be needed. Presentation of a category (analogously to presentation of a group) can in fact be approached in a number of ways, the category structure not being (quite) an algebraic structure in its own right.

Structure (disambiguation)

The structure of a thing is how the parts of it relate to each other, how it is "assembled".
