Nuveen North Carolina Dividend Advantage Municipal Fund 2
Nuveen is an American asset manager and wholly owned subsidiary of financial planning firm TIAA, itself known for its legacy focus on managing money for not-for-profit institutions such as universities and their employees. As a consequence of integration efforts over the last several years, Nuveen (or branded sub-affiliates) now manage the entirety of TIAA's own capital as well as all capital sourced from third parties. It is one of a limited number of non-sovereign money managers globally that have exceeded one trillion dollars in assets under management in recent years, and one of only a few that are not part of a larger organization offering retail or institutional banking at scale. Nuveen was founded in Chicago, Illinois in 1898 and originally focused solely on municipal bond underwriting and investments. While its investments today span nearly all major areas of capital markets, it is known for its size and influence in domestic fixed income generally, tax advantaged municipa ...

Natural Number Object
In category theory, a natural numbers object (NNO) is an object endowed with a recursive structure similar to natural numbers. More precisely, in a category E with a terminal object 1, an NNO ''N'' is given by: # a global element ''z'' : 1 → ''N'', and # an arrow ''s'' : ''N'' → ''N'', such that for any object ''A'' of E, global element ''q'' : 1 → ''A'', and arrow ''f'' : ''A'' → ''A'', there exists a unique arrow ''u'' : ''N'' → ''A'' such that: # ''u'' ∘ ''z'' = ''q'', and # ''u'' ∘ ''s'' = ''f'' ∘ ''u''. In other words, the triangle and square in the following diagram commute. The pair (''q'', ''f'') is sometimes called the ''recursion data'' for ''u'', given in the form of a recursive definition: # ⊢ ''u'' (''z'') = ''q'' # ''y'' ∈E ''N'' ⊢ ''u'' (''s'' ''y'') = ''f'' (''u'' (''y'')) The above definition is the universal property of NNOs, meaning they are defined up to canonical isomorphism. If the arrow ''u'' as defined above merely has to exist, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Category Theory
Category theory is a general theory of mathematical structures and their relations that was introduced by Samuel Eilenberg and Saunders Mac Lane in the middle of the 20th century in their foundational work on algebraic topology. Nowadays, category theory is used in almost all areas of mathematics, and in some areas of computer science. In particular, many constructions of new mathematical objects from previous ones, that appear similarly in several contexts are conveniently expressed and unified in terms of categories. Examples include quotient spaces, direct products, completion, and duality. A category is formed by two sorts of objects: the objects of the category, and the morphisms, which relate two objects called the ''source'' and the ''target'' of the morphism. One often says that a morphism is an ''arrow'' that ''maps'' its source to its target. Morphisms can be ''composed'' if the target of the first morphism equals the source of the second one, and morphism compos ...

National Night Out
National Night Out is a community-police awareness-raising event in the United States, held the first Tuesday of August (Texas celebrates on the first Tuesday in October). History The event has been held annually since 1984, and is sponsored by the National Association of Town Watch in the United States.Block, Deborah (August 3, 2016).. ''VOA News''. National Night Out began simply with neighbors turning on their porch lights and sitting in front of their homes. The first National Night Out involved 2.5 million residents across 400 communities in 23 states; National Night Out 2016 involved 38 million residents in 16,000 communities across the United States. Activities The event is meant to increase awareness about police programs in communities, such as drug prevention, town watch, neighborhood watch, and other anti-crime efforts. The events are typically organized by block watches, nonprofit organizations, companies, and police departments. These events can be as simple as back ...

Nynorsk
Nynorsk () () is one of the two written standards of the Norwegian language, the other being Bokmål. From 12 May 1885, it became the state-sanctioned version of Ivar Aasen's standard Norwegian language ( no, Landsmål) parallel to the Dano-Norwegian written language (''Riksmål''). Nynorsk became the name in 1929, and it is after a series of reforms still a variation which is closer to , whereas Bokmål is closer to ''Riksmål'' and Danish. Between 10 and 15 percent of Norwegians (Primarily in the west around the city of Bergen,) have Nynorsk as their official language form, estimated by the number of students attending ''videregående skole'' (secondary education). Nynorsk is also taught as a mandatory subject in both high school and elementary school for all Norwegians who do not have it as their own language form. History Danish was the written language of Norway until 1814, and Danish with Norwegian intonation and pronunciation was on occasion spoken in the cities (see Da ...
