Envy-free Item Allocation
Envy-free (EF) item allocation is a fair item allocation problem, in which the fairness criterion is envy-freeness - each agent should receive a bundle that they believe to be at least as good as the bundle of any other agent.:296–297 Since the items are indivisible, an EF assignment may not exist. The simplest case is when there is a single item and at least two agents: if the item is assigned to one agent, the other will envy. Therefore, the division procedures provide various kinds of relaxations.

Gladstonian Liberalism
Gladstonian liberalism is a political doctrine named after the United Kingdom Victorian Prime Minister and leader of the Liberal Party, William Ewart Gladstone. Gladstonian liberalism consisted of limited government expenditure and low taxation whilst making sure government had balanced budgets and the classical liberal stress on self-help and freedom of choice. Gladstonian liberalism also emphasised free trade, little government intervention in the economy and equality of opportunity through institutional reform. It is referred to as laissez-faire or classical liberalism in the United Kingdom and is often compared to Thatcherism. Gladstonian financial rectitude had a partial lasting impact on British politics and the historian John Vincent contends that under Lord Salisbury's premiership he "left Britain's low tax, low cost, low growth economy, with its Gladstonian finance and its free trade dogmas, and no conscript army, exactly as he had found it...Salisbury reigned, but Gladstone ruled". However, in the early 20th-century the Liberal Party began to move away from Gladstonian liberalism and instead developed new policies based on social liberalism (or what Gladstone called "constructionism"). The Liberal government of 1906–1914 is noted for its social reforms and these included old age pensions and National Insurance. Taxation and public expenditure was also increased and New Liberal ideas led to David Lloyd George's People's Budget of 1909–1910. The first Labour Chancellor of the Exchequer, Philip Snowden, had Gladstonian economic views. This was demonstrated in his first Budget in 1924 as government expenditure was curtailed, taxes were lowered and duties on tea, coffee, cocoa and sugar were reduced. Historian A. J. P. Taylor remarked that this budget "would have delighted the heart of Gladstone". Ernest Bevin remarked on becoming Minister of Labour in 1940: "They say that Gladstone was at the Treasury from 1860 to 1930".

Bonded Warehouse
A bonded warehouse, or bond, is a building or other secured area in which dutiable goods may be stored, manipulated, or undergo manufacturing operations without payment of duty. It may be managed by the state or by private enterprise. In the latter case a customs bond must be posted with the government. This system exists in all developed countries of the world. Upon entry of goods into the warehouse, the importer and warehouse proprietor incur liability under a bond. This liability is generally cancelled when the goods are: While the goods are in the bonded warehouse, they may, under supervision by the customs authority, be manipulated by cleaning, sorting, repacking, or otherwise changing their condition by processes that do not amount to manufacturing. After manipulation, and within the warehousing period, the goods may be exported without the payment of duty, or they may be withdrawn for consumption upon payment of duty at the rate applicable to the goods in their manipulated condition at the time of withdrawal. In the United States, goods may remain in the bonded warehouse up to five years from the date of importation. Bonded warehouses provide specialized storage services such as deep freeze or bulk liquid storage, commodity processing, and coordination with transportation, and are an integral part of the global supply chain.

Horizon (IT System)
Horizon is a computer system used by part of the United Kingdom's postal service, Post Office Ltd. In 2013 the system was being used by at least 11,500 branches, and was processing some six million transactions every day. Horizon was introduced in 1999, and from then onwards unexplained discrepancies and losses began to be reported by sub-postmasters. The Post Office maintained that Horizon was "robust" and that none of the shortfalls or discrepancies in sub-postmasters' branch accounts were due to problems caused by Horizon. Sub-postmasters unwilling or unable to make good the shortfalls were sometimes prosecuted (by the Post Office's in-house prosecution team) for theft, false accounting and/or fraud. This was done on IT evidence alone, without proof of criminal intent. Despite this, some sub-postmasters were successfully persuaded by their own solicitors to plead guilty to false accounting, on being told the Post Office would drop theft charges. Once the Post Office had a criminal conviction, it would attempt to secure a Proceeds of Crime Act Order against convicted sub-postmasters, allowing it to seize their assets and bankrupt them. According to press reports, these actions by the Post Office caused the loss of dozens of jobs, bankruptcy, divorce, unwarranted prison sentences and one documented suicide. In 2019 the Horizon Issues trial judgment in the Bates & Ors v Post Office Ltd group litigation at the High Court found that bugs, errors and defects did exist and that it was possible for these to cause apparent discrepancies or shortfalls in branch accounts or transactions, and to undermine the reliability of Horizon accurately to process and to record transactions. Mr Justice Fraser found that this had happened on numerous occasions. In September 2020, the Post Office declared it would not oppose 44 postmasters' appeals against conviction. In December 2020 six convictions were quashed, and in April 2021 the Court of Appeal quashed a further 39 people's convictions. The BBC called the convictions "the UK's most widespread miscarriage of justice". In April 2021 Post Office Chief Executive Nick Read announced that the Horizon system would be replaced with a new cloud-based IT system.

Mnemonic
A mnemonic (/nəˈmɒnɪk/) device, or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory for better understanding. Mnemonics make use of elaborative encoding, retrieval cues, and imagery as specific tools to encode information in a way that allows for efficient storage and retrieval. Mnemonics aid original information in becoming associated with something more accessible or meaningful—which, in turn, provides better retention of the information. Commonly encountered mnemonics are often used for lists and in auditory form, such as short poems, acronyms, initialisms, or memorable phrases, but mnemonics can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous, or otherwise "relatable" information, rather than more abstract or impersonal forms of information. The word "mnemonic" is derived from the Ancient Greek word μνημονικός (mnēmonikos), meaning 'of memory' or 'relating to memory' and is related to Mnemosyne ("remembrance"), the name of the goddess of memory in Greek mythology. Both of these words are derived from μνήμη (mnēmē), 'remembrance, memory'. Mnemonics in antiquity were most often considered in the context of what is today known as the art of memory. Ancient Greeks and Romans distinguished between two types of memory: the "natural" memory and the "artificial" memory. The former is inborn, and is the one that everyone uses instinctively. The latter in contrast has to be trained and developed through the learning and practice of a variety of mnemonic techniques. Mnemonic systems are techniques or strategies consciously used to improve memory. They help use information already stored in long-term memory to make memorization an easier task.

Virtual Reality and Metacognition for Learning Disabilities
Learning disabilities are defined as a set of neurodevelopmental disorders of biological basis that induce cognitive abnormalities as well as symptoms related to emotional and behavioral disorders. Metacognition is defined by Drigas and Mitsea as the “set of regulatory meta-abilities and meta-skills that are consciously applied aiming at the smooth operation of the cognitive & psychophysiological mechanism as a means of achieving functional capability, self-efficacy, independent living & life satisfaction. Virtual reality (VR) is commonly regarded as a technology that induces virtual immersion in a digital world via the use of a computerized graphic simulation that allows users to immerse themselves in an interactive three-dimensional world brimming with various sensory and emotional experiences.

Maquis Du Vercors
The Maquis du Vercors was a rural group of the French Forces of the Interior (FFI) (maquis) that resisted the 1940–1944 German occupation of France in World War II. The Maquis du Vercors used the prominent scenic plateau known as the Massif du Vercors (Vercors Plateau) as a refuge. Initially the maquis carried out only sabotage and partisan operations against the Germans, but after the Normandy Invasion on 6 June 1944, the leadership of an army of about 4,000 maquis declared the "Free Republic of Vercors," raised the French flag, and attempted to create a conventional army to oppose the German occupation. The allies supported the maquis with parachute drops of weapons and by supplying teams of advisors and trainers, but the uprising was premature. In July 1944 as many as 10,000 German soldiers invaded the massif and killed more than 600 of the maquis, known as maquisards, and 200 civilians. It was German's largest anti-partisan operation in Western Europe during World War II. In August 1944, shortly after the battle for the Vercors, the area was liberated from German control by the American army allied with the FFI.

Six-factor Model of Psychological Well-being
The Six-factor Model of Psychological Well-being is a theory developed by Carol Ryff which determines six factors which contribute to an individual's psychological well-being, contentment, and happiness. Psychological well-being consists of positive relationships with others, personal mastery, autonomy, a feeling of purpose and meaning in life, and personal growth and development. Psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events.

Testing Effect
The testing effect is the finding that long-term memory is often increased when some of the learning period is devoted to retrieving the to-be-remembered information. The effect is also sometimes referred to as retrieval practice, practice testing, or test-enhanced learning. Retrieval practice may be the best way to refer to the testing effect because the benefits of retrieval-related testing are not limited to tests. It can be more broad, including tools like flash cards and quizzes. The testing effect on memory should be distinguished from more general practice effects, defined in the APA Dictionary of Psychology (2007) as "any change or improvement that results from practice or repetition of task items or activities." The term testing effect is also sometimes used in a more general sense; The Oxford Dictionary of Psychology (2003) defines a testing effect as "any effect of taking tests on the respondents, a typical example being test sophistication." Whereas psychologists who develop tests for personality and intelligence want to avoid practice effects, cognitive psychologists working with educators have begun to understand how to take advantage of tests—not as an assessment tool, but as a teaching/learning tool. It is useful for people to test their knowledge of the to-be-remembered material during the learning process, instead of only reading or otherwise passively studying the material. For example, a student can use flashcards to self-test and receive feedback as they study. The testing effect provides a larger benefit to long-term memory when the tested material is difficult enough to require effort, the rate of retrieval success is high, and feedback with correct answers is given after testing. The testing effect is activated by active recall.
