Political representation

POLITICAL ACTORS MAKING CITIZENS "PRESENT" IN PUBLIC POLICY MAKING PROCESSES

Descriptive representation; Substantive representation; One state, one vote; Representation by population; Substantive Representation; Rep by pop; Rep-by-pop; Models of representation; Representation by area; Politico model of representation; Representation (politics)

Political representation is the activity of making citizens "present" in public policy making processes when political actors act in the best interest of citizens. This definition of political representation is consistent with a wide variety of views on what representing implies and what the duties of representatives are.

Mental representation

HYPOTHETICAL INTERNAL COGNITIVE SYMBOL THAT REPRESENTS EXTERNAL REALITY

Representation (psychology); Representational theory of mind; Having an idea; Conceive an idea; Conceiving an idea; Good idea; Representation level; Level of representation; Directedness; Presentation (philosophy); Idea in anthropology

A mental representation (or cognitive representation), in philosophy of mind, cognitive psychology, neuroscience, and cognitive science, is a hypothetical internal cognitive symbol that represents external reality, or else a mental process that makes use of such a symbol: "a formal system for making explicit certain entities or types of information, together with a specification of how the system does this".

Numeral system

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.

The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number eleven in the decimal numeral system (today, the most common system globally), the number three in the binary numeral system (used in modern computers), and the number two in the unary numeral system (used in tallying scores).

The number the numeral represents is called its value. Not all number systems can represent the same set of numbers; for example, Roman numerals cannot represent the number zero.

Ideally, a numeral system will:

Represent a useful set of numbers (e.g. all integers, or rational numbers)
Give every number represented a unique representation (or at least a standard representation)
Reflect the algebraic and arithmetic structure of the numbers.

For example, the usual decimal representation gives every nonzero natural number a unique representation as a finite sequence of digits, beginning with a non-zero digit.

Numeral systems are sometimes called number systems, but that name is ambiguous, as it could refer to different systems of numbers, such as the system of real numbers, the system of complex numbers, the system of p-adic numbers, etc. Such systems are, however, not the topic of this article.
