Context paragraphs:
Victor Nendaka Bika: Victor Nendaka Bika (7 August 1923 – 22 August 2002) was a Congolese politician from the Democratic Republic of Congo (previously known as Zaire).  Nicknamed "Oufkir" reminding Mohamed Oufkir, the right-hand man of King Hassan II in the 1960s and early 1970s, Victor Nendaka was the first Director of "Sûreté Nationale du Congo" (Congo's Security Services) after independence in June 1960.  Nendaka once belonged to the Congolese National Movement (MNC) of Patrice Lumumba.  For personal reasons, Victor quit the MNC and created MNC-Nendaka in March 1960.  In his capacity as Head of Security Services, Nendaka is believed to have played a paramount role in the arrest, torture and transfer of Patrice Lumumba to Lubumbashi (then Elisabethville) where the first Congolese Prime Minister Patrice Lumumba was brutally executed; allegations that Victor Nendaka vehemently denied on several occasions, one of which being at the hearings of the Lumumba's commission at the initiative of the Belgian Chamber of Representatives.  Victor Nendaka died on Thursday, 22 August 2002, at age 79, while in exile in Brussels, after Mobutu's regime was overthrown by the Alliance of Democratic Forces for the Liberation of Congo (AFDL or ADFLC) led by rebel leader Laurent-Désiré Kabila and backed by President Paul Kagame's Rwanda in 1997.

Juan Perón: Juan Domingo Perón (] ; 8 October 1895 – 1 July 1974) was an Argentine lieutenant general and politician.  After serving in several government positions, including Minister of Labour and Vice President, he was thrice elected President of Argentina, serving from June 1946 to September 1955, when he was overthrown in a "coup d'état", and then from October 1973 until his death in July 1974.

Cicaré CK.1: The Cicaré CK.1 (originally, the CH.III Colibrí) was a light helicopter developed in Argentina in the 1970s.  It was a small, single-rotor aircraft of pod-and-boom configuration with a fully enclosed bubble canopy that could seat three people side-by-side.  Cicaré's previous helicopter designs had attracted the attention of the Argentine Air Force, which in 1974 contracted him to develop a light helicopter for training and also marketed for agricultural use.  A prototype, registered "LV-X62" flew in September 1976, and the Air Force placed an order for five pre-production machines.  However, development was terminated at this point.

Empowering Effective Teachers: Empowering Effective Teachers is an initiative started by the School District of Hillsborough County, Florida, in hopes of promoting improvements in education by increasing effective teaching through new evaluations or teacher assessments and salary scales as well as new teacher training programs and recruitment.  This initiative developed through a partnership and grant with the Bill and Melinda Gates Foundation.  The early phases of this new initiative rolled out in 2010 when teachers observation evaluation form was radically redeveloped into a complex rubric with four overall areas of focus—Planning and Preparation, Classroom Environment, Instruction, and Professional Responsibilities—each with multiple, specific sub points.  Each point has four possible categories—Requires Action, Progressing, Accomplished, and Exemplary—in which the teacher can fall.

Ignalina Nuclear Power Plant: The Ignalina Nuclear Power Plant (Lithuanian: "Ignalinos Atominė Elektrinė, IAE" , Russian: Игналинская атомная электростанция, "Ignalinskaya atomnaya elektrostantsiya" ) is a closed two-unit RBMK-1500 nuclear power station in Visaginas municipality, Lithuania.  It was named after the nearby city of Ignalina.  Due to the plant's similarities to the failed Chernobyl Nuclear Power Plant in both reactor design and lack of a robust containment building, Lithuania agreed to close the plant as part of its accession agreement to the European Union.  Unit 1 was closed in December 2004.  The remaining Unit 2 which counted for 25% of Lithuania's electricity generating capacity and supplied about 70% of Lithuania's electrical demand, was closed on December 31, 2009.  Proposals have been made to construct a new nuclear power plant at the same site.

I.Ae. 31 Colibrí: The IAe.31 "Colibrí" ("Hummingbird") was a civil trainer aircraft developed in Argentina in the 1940s.  It was designed by Émile Dewoitine and developed by the Instituto Aerotécnico for manufacture by the company H. Goberna factories in Córdoba Province as an initiative under President Juan Perón's first five year plan.

Focke-Wulf Ta 183: The Focke-Wulf Ta 183 "Huckebein" was a design for a jet-powered fighter aircraft intended as the successor to the Messerschmitt Me 262 and other day fighters in Luftwaffe service during World War II.  It was developed only to the extent of wind tunnel models when the war ended, but the basic design was further developed postwar in Argentina as the FMA IAe 33 Pulqui II.  The name "Huckebein" is a reference to a trouble-making raven ("Hans Huckebein der Unglücksrabe") from an illustrated story in 1867 by Wilhelm Busch.

Mehmed IV: Mehmed IV (Ottoman Turkish: محمد رابع "Meḥmed-i rābiʿ"; Modern Turkish: "IV.  Mehmet"; also known as "Avcı Mehmed", Mehmed the Hunter; 2 January 1642 – 6 January 1693) was the Sultan of the Ottoman Empire from 1648 to 1687.  He came to the throne at the age of six after his father was overthrown in a coup.  Mehmed went on to become the second longest reigning sultan in Ottoman history.  While the first and last years of his reign were characterized by military defeat and political instability, during his middle years he oversaw the revival of the empire's fortunes associated with the Köprülü era.  Mehmed IV was known by contemporaries as a particularly pious ruler, and was referred to as gazi, or "holy warrior" for his role in the many conquests carried out during his long reign.  Under his reign the empire reached the height of its territorial expansion in Europe.  From a young age he developed a keen interest in hunting, for which he is known as "avcı" (translated as "the Hunter").  In 1687 Mehmed was overthrown by soldiers disenchanted by the course of the ongoing War of the Holy League.  He subsequently retired to Edirne, where he resided until his natural death in 1693.

BRAIN Initiative: The White House BRAIN Initiative (Brain Research through Advancing Innovative Neurotechnologies), is a collaborative, public-private research initiative announced by the Obama administration on April 2, 2013, with the goal of supporting the development and application of innovative technologies that can create a dynamic understanding of brain function.  This activity is a Grand Challenge focused on revolutionizing our understanding of the human brain, and was developed by the White House Office of Science and Technology Policy (OSTP) as part of a broader White House Neuroscience Initiative.  Inspired by the Human Genome Project, BRAIN aims to help researchers uncover the mysteries of brain disorders, such as Alzheimer's and Parkinson's diseases, depression, and traumatic brain injury (TBI).

Music Encoding Initiative: The Music Encoding Initiative (MEI) is an open-source effort to create a system for representation musical documents in a machine-readable structure.  MEI closely mirrors work done by text scholars in the Text Encoding Initiative (TEI) and while the two encoding initiatives are not formally related, they share many common characteristics and development practices.  The term "MEI", like "TEI", describes the governing organization and the markup language.  The MEI community solicits input and development directions from specialists in various music research communities, including technologists, librarians, historians, and theorists in a common effort to discuss and define best practices for representing a broad range of musical documents and structures.  The results of these discussions are then formalized into the MEI schema, a core set of rules for recording physical and intellectual characteristics of music notation documents.  This schema is expressed in an XML Schema Language, with RelaxNG being the preferred format.  The MEI schema is developed using the One-Document-Does-it-all (ODD) format, a literate programming XML format developed by the Text Encoding Initiative.
