Spaced Retrieval
Spaced retrieval, also known as expanded retrieval, is a learning technique, which requires users to rehearse information to be learned at different and increasing spaced intervals of time. In testing this type of learning, people are instructed to rehearse a given set of information at a certain time, and each new rehearsal is expected to have a longer period of time between itself and the previous rehearsal or an equal amount of time between rehearsals. At the end of every trial period there is a test phase. Landauer and Bjork first studied this technique of learning in 1978. The study required participants to learn names from flash cards. Prior to learning participants were placed into five different rehearsal types: uniform short, uniform moderate, uniform long, expanding, and contracting. These all indicate the amount and spacing of trials between each test. Uniform trials involve a number of trials between each test stage, but the trial numbers are fixed (e.g. 2-test-2-test-2-test). Contracting rehearsals involve larger intervals of time between the first few trials and the test phase, but eventually the trials decrease in number. Expanding involves starting with trials and tests close together, and as they progress the person would have more time between each trial and test (e.g. 1-test-2-test-3-test). The effectiveness of the rehearsal types was measured by seeing how accurately participants responded during a test phase. Expanding was proven to be the most important because it produced the highest amount of recall during the test period. The data behind this initial research indicated that an increasing space between rehearsals (expanding) would yield a greater percentage of accuracy at test points. Spaced retrieval with expanding intervals is believed to be so effective because with each expanded interval of retrieval it becomes more difficult to retrieve the information because of the time elapsed between test periods; this creates a deeper level of processing of the learned info in long term memory at each point. Another reason that the expanding retrieval model is believed to work so effectively is because the first test happens early on in the rehearsal process. The purpose of this is to increase retrieval success. By having a first test that followed initial learning with a successful retrieval, people are more likely to remember this successful retrieval on following tests. Although expanding retrieval is commonly associated with spaced retrieval, a uniform retrieval schedule is also a form of spaced retrieval procedure. Spaced retrieval is typically studied through the use of memorizing facts. Traditionally speaking, it has not been applied to fields that required some manipulation or thought beyond simple factual/semantic information. A more recent study has shown that spaced retrieval can benefit tasks such as solving math problems. In a study conducted by Pashler, Rohrer, Cepeda, and Carpenter, participants had to learn a simple math principle in either a spaced or massed retrieval schedule. The participants given the spaced retrieval learning tasks showed higher scores on a final test distributed after their final practice session. This is unique in the sense that it shows spaced retrieval can be used to not only remember simple facts or contextual data, but it can also be used in fields, such as math, where manipulation and the use of particular principles or formulas (e.g. y = mx + b) is necessary. These researchers also found that it is beneficial for feedback to be applied when administering the tests. When a participant gave a wrong response, they were likely to get it correct on following tests if the researcher gave them the correct answer after a delayed period. Spaced retrieval is a useful tool for learning that is relevant to many domains such as fact learning or mathematics, and many different tasks (expanding or uniform retrieval). Many studies over the years have contributed to the use and implementation of spaced retrieval, and it still remains a subject of interest for many researchers.

Khitan Scripts
The Khitan scripts were the writing systems for the now-extinct Para-Mongolic Khitan language used in the 10th-12th century by the Khitan people who had established the Liao dynasty in Northeast China. There were two scripts, the large script (Chinese: 契丹大字; pinyin: qìdān dàzì) and the small script (Chinese: 契丹小字; pinyin: qìdān xiǎozì). These were functionally independent and appear to have been used simultaneously. The Khitan scripts continued to be in use to some extent by the Jurchen people for several decades after the fall of the Liao dynasty until the Jurchens fully switched to a script of their own. Examples of the scripts appeared most often on epitaphs and monuments, although other fragments sometimes surface. Many scholars recognize that the Khitan scripts have not been fully deciphered and that more research and discoveries would be necessary for a proficient understanding of them. The Khitan scripts are part of the Chinese family of scripts. Knowledge of the Khitan language, which was written by the Khitan script, is quite limited as well. Although there are several clues to its origins, which might point in different directions, the Khitan language shares an ancestor with the Mongolian languages but is not one.

Veritatis Splendor
Encyclical Veritatis splendor (Latin: The Splendor of the Truth) is an encyclical by Pope John Paul II. It expresses the position of the Catholic Church regarding fundamentals of the Church's role in moral teaching. The encyclical is one of the most comprehensive and philosophical teachings of moral theology in the Catholic tradition. It was promulgated on 6 August 1993. Cardinal Georges Cottier, Theologian emeritus of the Pontifical Household and Cardinal-Deacon of Santi Domenico e Sisto the University Church of the Pontifical University of Saint Thomas Aquinas was influential in drafting the encyclical, as was Servais-Théodore Pinckaers, a professor of moral theology at the University of Fribourg, while others stress its lasting validity and importance.

Teacher Professional Development in STEM Education
The implementation of an integrated approach of STEM (Science, Technology, Engineering and Mathematics) education with real-life scenarios is crucial to motivate students to learn and to better prepare them for real-world problems, which is a big challenge for teachers. By an integrated approach of STEM education in class, it is considered tasks that preferably include content related to all four of the STEM subjects included in the acronym. In addition, at the elementary level (e.g., primary school), it is recommended that tasks are introduced to students guided by the teacher in order to be adequate to their age. In this regard, teachers need to create a guided discovery environment to promote students’ learning in STEM subjects. Therefore, teachers need to participate in effective in-service professional development programmes to gain knowledge and skills to be able to develop this approach.

Students' Union
A students' union, student government, free student union, student senate, students' association, guild of students, or government of student body is a student organization present in many colleges, universities, and high schools. In higher education, the students' union is often accorded its own building on the campus, dedicated to social, organizational activities, representation, and academic support of the membership. In the United States, student union often only refers to a physical building owned by the university with the purpose of providing services for students without a governing body. This building is also referred to as a student activity center, although the Association of College Unions International (largely US-based) has hundreds of campus organizational members. Outside the US, student union and students' union refer to a representative body, as distinct from a student activity centre.

Postal Censorship
Postal censorship is the inspection or examination of mail, most often by governments. It can include opening, reading and total or selective obliteration of letters and their contents, as well as covers, postcards, parcels and other postal packets. Postal censorship takes place primarily but not exclusively during wartime (even though the nation concerned may not be at war, e.g. Ireland during 1939–1945) and periods of unrest, and occasionally at other times, such as periods of civil disorder or of a state of emergency. Both covert and overt postal censorship have occurred. Historically, postal censorship is an ancient practice; it is usually linked to espionage and intelligence gathering. Both civilian mail and military mail may be subject to censorship, and often different organisations perform censorship of these types of mail. In 20th-century wars the objectives of postal censorship encompassed economic warfare, security and intelligence. The study of postal censorship is a philatelic topic of postal history.

Values in Action Inventory of Strengths
The VIA Inventory of Strengths (VIA-IS), formerly known as the "Values in Action Inventory," is a proprietary psychological assessment measure designed to identify an individual's profile of character strengths. It was created by Christopher Peterson and Martin Seligman, well-known researchers in the field of positive psychology, in order to operationalize their Character Strengths and Virtues Handbook (CSV). The CSV is the positive psychology counterpart to the Diagnostic and Statistical Manual of Mental Disorders (DSM) used in traditional psychology. Unlike the DSM, which scientifically categorizes human deficits and disorders, the CSV classifies positive human strengths. Moreover, the CSV is centered on helping people recognize and build upon their strengths. This aligned with the overall goal of the positive psychology movement, which aims to make people's lives more fulfilling, rather than simply treating mental illness. Notably, the VIA-IS is the tool by which people can identify their own positive strengths and learn how to capitalize on them.

Hungarian Irredentism
Hungarian irredentism or Greater Hungary are irredentist and revisionist political ideas concerning redemption of territories of the historical Kingdom of Hungary. The idea is associated with Hungarian revisionism, targeting at least to regain control over Hungarian-populated areas in Hungary's neighbouring countries. Hungarian historians did not use the term Greater Hungary, because the "Historic Hungary" is the established term for the Kingdom of Hungary before 1920. The Treaty of Trianon defined the borders of the new independent Hungary and, compared against the claims of the pre-war Kingdom, new Hungary had approximately 72% less land stake and about two-thirds fewer inhabitants, almost 5 million of these being of Hungarian ethnicity. However, only 54% of the inhabitants of the pre-war Kingdom of Hungary were Hungarians before World War I. Following the treaty's instatement, Hungarian leaders became inclined towards revoking some of its terms. This political aim gained greater attention and was a serious national concern up through the second World War. Irredentism in the 1930s led Hungary to form an alliance with Hitler's Germany. Eva S. Balogh states: "Hungary's participation in World War II resulted from a desire to revise the Treaty of Trianon so as to recover territories lost after World War I. This revisionism was the basis for Hungary's interwar foreign policy." Hungary, supported by the Axis Powers, was successful temporarily in gaining some regions of the former Kingdom by the First Vienna Award in 1938 (southern Czechoslovakia with mainly Hungarians) and the Second Vienna Award in 1940 (Northern Transylvania with a significant Romanian population as well), and through military campaign gained regions of Carpathian Ruthenia in 1939 and (ethnically mixed) Bačka, Baranja, Međimurje, and Prekmurje in 1941 (Hungarian occupation of Yugoslav territories). Following the close of World War II, the borders of Hungary as defined by the Treaty of Trianon were restored, except for three Hungarian villages that were transferred to Czechoslovakia. These villages are today administratively a part of Bratislava.

Jackson Family
The Jackson family is an important and influential American family of singers that has garnered prominence in the music industry, originated from Gary, Indiana. Performing as members of The Jackson 5 and as solo artists, the children of Joseph Walter and Katherine Esther Jackson were very successful in the field of popular music from the late 1960s onwards. As a group, the eldest sons Jackie, Tito, Jermaine, Marlon, Michael, and later with the inclusion of Randy. The members who managed to be solo icons in music are Michael Jackson and Janet Jackson. The Jackson 5 became known as the "First Family of Soul" (a title first held by the Five Stairsteps). The continued success of Michael and Janet's careers as solo artists led the Jacksons to become known as the "Royal Family of Pop". All nine of the Jackson siblings have gold records to their credits with La Toya holding the distinction of being the first Jackson sister to attain one (awarded by France's SNEP for "Reggae Night", a song she co-wrote for Jimmy Cliff), and now to Janet Jackson for being the first black woman to receive the Billboard Icon Award. The Jackson family has been the subject of controversy linked to the Jordan Chandler Case. But the most controversial facts of Jackson's private life are accusations made by his sons against family patriarch Joseph Jackson claiming that he was harassed by his father as a child. Despite these circumstances and other problems, the Jacksons continued to be one of the most influential families in the United States and in recent years some family members have been honored for their work; in 1997 The Jackson 5 was inducted to the Rock and Roll Hall of Fame. Michael would follow the group to the hall in 2001. The Jacksons, Michael and Janet all received stars on the Hollywood Walk of Fame in 1980, 1984 and 1990 respectively. Joseph was recognized as "the best musical businessman of all time" by the city of Cleveland in 2002. In 2009 a new series from A&E entitled The Jacksons: A Family Dynasty premiered documenting the Jackson brothers dealing with the sudden loss of Michael and preparing for a Jackson 5 Reunion tour. The most popular member of the Jackson family was Michael Jackson, known as the King of Pop and died in June 2009, due to a cardiac arrest.
