International Relations
International relations (IR), sometimes referred to as international studies and international affairs, is the scientific study of interactions between sovereign states. In a broader sense, it concerns all activities between states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organisations (IGOs), international nongovernmental organisations (INGOs), international legal bodies, and multinational corporations (MNCs). There are several schools of thought within IR, of which the most prominent are realism, liberalism, and constructivism. International relations is widely classified as a major subdiscipline of political science, along with comparative politics and political theory. However, it often draws heavily from other fields, including anthropology, economics, geography, law, philosophy, sociology, and history. While international politics has been analyzed since antiquit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relational Model
The relational model (RM) is an approach to managing data using a Structure (mathematical logic), structure and language consistent with first-order logic, first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, where all data is represented in terms of tuples, grouped into relation (database), relations. A database organized in terms of the relational model is a relational database. The purpose of the relational model is to provide a Declarative programming, declarative method for specifying data and queries: users directly state what information the database contains and what information they want from it, and let the database management system software take care of describing data structures for storing the data and retrieval procedures for answering queries. Most relational databases use the SQL data definition and query language; these systems implement what can be regarded as an engineering approximation to the relational model. A ''t ...

Coefficient Of Relationship
The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy. A coefficient of inbreeding can be calculated for an individual, and is typically one-half the coefficient of relationship between the parents. In general, the higher the level of inbreeding the closer the coefficient of relationship between the parents approaches a value of 1, expressed as a percentage, and approaches a value of 0 for individuals with arbitrarily remote common ancestors. Coefficient of relationship The coefficient of relationship ( r ) between two individuals B and C is obtained by a summation of coefficients calculated for every line by which they are connected to their identical ancestors point, common ancestors.

Kinship
In anthropology, kinship is the web of social relationships that form an important part of the lives of all humans in all societies, although its exact meanings even within this discipline are often debated. Anthropologist Robin Fox says that the study of kinship is the study of what humans do with these basic facts of lifemating, gestation, parenthood, socialization, siblingship etc. Human society is unique, he argues, in that we are "working with the same raw material as exists in the animal world, but ecan conceptualize and categorize it to serve social ends." These social ends include the socialization of children and the formation of basic economic, political and religious groups. Kinship can refer both to the patterns of social relationships themselves, or it can refer to the study of the patterns of social relationships in one or more human cultures (i.e. kinship studies). Over its history, anthropology has developed a number of related concepts and terms in the study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Relation Aller Fürnemmen Und Gedenckwürdigen Historien
Johann Carolus (26 March 1575 − 15 August 1634) was a German publisher of the first newspaper, called ''Relation aller Fürnemmen und gedenckwürdigen Historien'' (Account of all distinguished and commemorable stories). The ''Relation'' is recognised by the World Association of Newspapers, as well as many authors, as the world's first newspaper. Carolus published the German-language newspaper in Strasbourg, which had the status of a free imperial city in the Holy Roman Empire of the German Nation. Life Johann Carolus was born in 1575 in Muhlbach-sur-Munster in the Holy Roman Empire of the German Nation. He was the son of a priest and his wife. He made an apprenticeship as a bookbinder and later worked as a bookseller, a scribe for a newspaper and as a printshop owner. Because of these professions, especially his job as scribe, he held good relationships to postmen and traders, what helped him later to create the ''Relation aller Fürnemmen und gedenckwürdigen Historien'' ...

Ontology Components
Contemporary ontologies share many structural similarities, regardless of the ontology language in which they are expressed. Most ontologies describe individuals (instances), classes (concepts), attributes, and relations. Overview Common components of ontologies include: ;Individuals: instances or objects (the basic or "ground level" objects). ;Classes: sets, collections, concepts, types of objects, or kinds of things. ;Attributes: aspects, properties, features, characteristics, or parameters that objects (and classes) can have. ; Relations: ways in which classes and individuals can be related to one another. ;Function terms: complex structures formed from certain relations that can be used in place of an individual term in a statement. ;Restrictions: formally stated descriptions of what must be true in order for some assertion to be accepted as input. ;Rules: statements in the form of an if-then (antecedent-consequent) sentence that describe the logical inferences that can be ...

Relational Database
A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using the SQL (Structured Query Language) for querying and maintaining the database. History The term "relational database" was first defined by E. F. Codd at IBM in 1970. Codd introduced the term in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by "relational". One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a minimum: # Present the data to the user as relati ...
