Context paragraphs:
Twinking: Twinking is a type of behavior in role-playing video games.  A player who engages in such behavior is known as a twink.  The precise definition of twinking varies depending on the variety of role-playing game.  In "pen and paper" role-playing games, a twink is often synonymous with a munchkin.  In MUDs, a twink is a player who is variously anything from a munchkin to a newbie to a griefer.  In MMORPGs, twinking refers to a character gaining equipment with the assistance of a higher level character, particularly by giving said low level character higher level equipment that is otherwise unattainable, or the process of keeping a video game character at a low level while using in-game currency, earned by a high level character, to provide it with superior equipment.

Northbound interface: In computer networking and computer architecture, a northbound interface of a component is an interface that conceptualizes the lower level details (e.g., data or functions) used by, or in, the component.  A northbound interface is used to interface with higher level layers using the southbound interface of the higher level component(s).  In architectural overviews, the northbound interface is normally drawn at the top of the component it is defined in, hence the name northbound interface.

Taiwanese nationalism: Taiwanese nationalism () is a nationalist political movement to unite residents of Taiwan as a nation and eliminate the current political and social division of Taiwan's people on the issues of national identity, the "Chinese reunification" vs. "independence" debate, and resolving the political status of Taiwan and its political dispute with China.  It is closely linked to Taiwan independence but distinguished from it in that the independence movement seeks to eventually establish an independent "Republic of Taiwan" in place of or out of the Republic of China and obtain United Nations and international recognition as a sovereign state (country), while the nationalism movement seeks only to establish or reinforce an independent Taiwanese identity that distinguishes Taiwan's people apart from Chinese nationalism, without necessarily advocating changing the official name of the Republic of China to "Republic of Taiwan".

Language education in Singapore: Singapore embraces an English-based bilingual education system.  Students are taught subject-matter curriculum with English as the medium of instruction, while the official mother tongue of each student - Mandarin Chinese for Chinese, Malay for Malays and Tamil for ethnically Tamil Indians – is taught as a second language.  Additionally, Higher Mother Tongue (HMT) is offered as an additional and optional examinable subject to those with the interest and ability to handle the higher standards demanded by HMT.  The content taught to students in HMT is of a higher level of difficulty and is more in-depth so as to help students achieve a higher proficiency in their respective mother tongues.  The choice to take up HMT is offered to students in the Primary and Secondary level.  Thereafter, in junior colleges, students who took HMT at the secondary level have the choice to opt out of mother tongue classes entirely.  Campaigns by the government to encourage the use of official languages instead of home languages (e.g. other Chinese varieties) have been largely successful, although English seems to be becoming the dominant language in most homes.  To date, many campaigns and programmes have been launched to promote the learning and use of mother tongue languages in Singapore.

Sinn Féin (slogan): Sinn Féin ("ourselves" or "we ourselves") and Sinn Féin Amháin ("ourselves only / ourselves alone / solely us") are Irish-language phrases used as a political slogan by Irish nationalists in the late nineteenth and early twentieth century.  While advocating Irish national self-reliance, its precise political meaning was undefined, variously interpreted as the aim of a separate Irish republic or (as advocated by Arthur Griffith) that of a dual monarchy.  Its earliest use was to describe individual political radicals unconnected with any party and espousing a more "advanced nationalism" than the Irish Home Rule movement.  In the 1890s "Sinn Féin, Sinn Féin amháin" was the slogan of the Gaelic League, which advocated the revival of the Irish language.

Political movement: In the social sciences, a political movement is a social group that operates together to obtain a political goal, on a local, regional, national, or international scope.  Political movements develop, coordinate, promulgate, revise, amend, interpret, and produce materials that are intended to address the goals of the base of the movement.  A social movement in the area of politics can be organized around a single issue or set of issues, or around a set of shared concerns of a social group.  In a political party, a political organization seeks to influence, or control, government policy, usually by nominating their candidates and seating candidates in political and government offices.  Additionally, parties participate in electoral campaigns and educational outreach or protest actions aiming to convince citizens or governments to take action on the issues and concerns which are the focus of the movement.  Parties often espouse an ideology, expressed in a party program, bolstered by a written platform with specific goals, forming a coalition among disparate interests.

National Institute for Higher Education: A National Institute for Higher Education (NIHE) (Irish: "Foras Náisiúnta um Ard-Oideachas" ) was a category of higher education institution established in Ireland to provide higher level technical education above the standard of the then established Regional Technical College system but at university level.  Higher level technical education in Ireland was seen to be an area that was poorly served until the advent of these institutions.

Irish Home Rule movement: The Irish Home Rule movement was a movement that agitated for self-government for Ireland within the United Kingdom of Great Britain and Ireland.  It was the dominant political movement of Irish nationalism from 1870 to the end of World War I.

Cache inclusion policy: Multi-level caches can be designed in various ways depending on whether the content of one cache is present in other level of caches.  If all blocks in the higher level cache are also present in the lower level cache, then the lower level cache is said to be inclusive of the higher level cache.  If the lower level cache contains blocks that are not present in the higher level cache, then the lower level cache is said to be exclusive of the higher level cache.  If the contents of the lower level cache are neither strictly inclusive nor exclusive of the higher level cache, then it is called non-inclusive non-exclusive (NINE) cache.

Greek nationalism: Greek nationalism (or Hellenic nationalism) refers to the nationalism of Greeks and Greek culture.  As an ideology, Greek nationalism originated and evolved in pre-modern times.  It became a major political movement beginning in the 18th century, which culminated in the Greek War of Independence (1821–1829) against the Ottoman Empire.  It became a potent movement in Greece shortly prior to, and during World War I under the leadership of nationalist figure Eleftherios Venizelos who pursued the Megali Idea and managed to liberate Greece in the Balkan Wars and after World War I, briefly annexed the region of İzmir before it was retaken by Turkey.  Today Greek nationalism remains important in the Greco-Turkish dispute over Cyprus.
