Soundscape archaeology
Through an approach that aims to recognise and investigate the religious and public spaces of the past as “embodied spaces” and “sensory artefacts”, we can raise hypotheses on the sound experience in the ancient world and on the complex relationship between spaces and social interactions, making use of the potential provided by the application of 3D technology to virtual acoustics.

South Korea's Green New Deal
Originally proposed as a post-COVID-19 stimulus plan, the Green New Deal is a sustainability-centered strategy for building a low-carbon and climate-neutral economy. The Green New Deal sets out eight targets to be accomplished under three strategic areas: green urban development, low-carbon decentralized energy, and innovative green industry. The Deal also takes measures to protect the people and sectors at a higher risk of being left behind in the process of the economic transition. It is an upgraded version of the “Green Growth” national policy, with more emphasis on sustainability in addition to the growth aspect.

Sovereign Citizen Movement
The sovereign citizen movement is a loose grouping of primarily American litigants, commentators, tax protesters, and financial-scheme promoters, who claim to be answerable only to their particular interpretations of the common law and to not be subject to any government statutes or proceedings. In the United States, they do not recognize U.S. currency and maintain that they are "free of any legal constraints". They especially reject most forms of taxation as illegitimate. Participants in the movement argue this concept in opposition to the idea of "federal citizens", who, they say, have unknowingly forfeited their rights by accepting some aspect of federal law. The doctrines of the movement resemble those of the freemen on the land movement more commonly found in the British Commonwealth, such as Australia and Canada. Many members of the sovereign citizen movement claim that the United States government is illegitimate. The sovereign citizen movement has been described as consisting of individuals who assert that the county sheriff is the most powerful law-enforcement officer in the country, with authority superior to that of any federal agent, elected official, or local law-enforcement official. The movement can be traced back to white-extremist groups like Posse Comitatus and the constitutional militia movement. It also includes members of certain self-declared "Moorish" sects. While the movement was originally associated with White supremacism, it now includes varying racial ideologies as well as a variety of people, most commonly white and African American. The Federal Bureau of Investigation (FBI) classifies some sovereign citizens ("sovereign citizen extremists") as domestic terrorists. In 2010, the Southern Poverty Law Center (SPLC) estimated that approximately 100,000 Americans were "hard-core sovereign believers", with another 200,000 "just starting out by testing sovereign techniques for resisting everything from speeding tickets to drug charges". In surveys conducted in 2014 and 2015, representatives of U.S. law enforcement ranked the risk of terrorism from the sovereign citizen movement higher than the risk from any other group, including Islamic extremists, militias, racists, and neo-Nazis. The New South Wales Police Force in Australia has also identified sovereign citizens as a potential terrorist threat.

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.

Spanish Baccalaureate
The Spanish Baccalaureate (Spanish: Bachillerato) is the post-16 stage of education in Spain, comparable to the A Levels/Higher (Scottish) in the UK, the French Baccalaureate in France or the International Baccalaureate. It follows the ESO (compulsory stage of secondary education). After taking the Bachillerato, a student may enter vocational training (Higher-level Training Cycles, Ciclos Formativos de Grado Superior) or take the "Selectividad" tests for admission to university. There are two parts, a core curriculum with the compulsory subjects and a specialist part with a number of pre-selected branches to choose from.

Spatial Attention Focus, Awareness in Emotion Processing
Emotional faces constitute important social information in the daily life. Expressions like fear can act as cues for potential threats in the environment and are therefore thought to be prioritised for attention. The relationship between attention and emotion processing have focused essentially on consciously-viewed, supraliminal stimuli, while the attention-emotion interplay remains unexplored in situations where visual awareness is restricted.

Spatial Distribution Suitability of Ethnic Minority Villages
Ethnic minority villages are important resources for the economy and social development of ethnic minority areas because they preserve ethnic minorities’ culture. With the rapid development of industrialization and urbanization in China, the factors affecting the development of villages have changed. With the help and guidance of the government, the gap between villages has increased. According to the development conditions of ethnic minority villages, the suitability of their spatial distribution has been studied, the existing problems in the current development have been explored, and the development laws and future development trends have been found.

Spatial Pattern of Cross-Border Area in China
With globalization and informatization, cross-border areas have become increasingly critical interactive spaces, experiencing rapid development and extensive changes in residents’ cross-border travel, constantly changing the spatial patterns of neighboring cities. Taking the Guangzhou-Foshan metropolitan area as a case, the research explored that a large number of cross-city trips for leisure and entertainment purposes emerged, and the one-way unbalanced flow, “Foshan to Guangzhou”, changed to two-way circulation. The spatial pattern of the Guangzhou-Foshan region from 1985 to 2020 to be on of spreading expansion, with Liwan District as the central core, connecting to several sub-centers. The cross-border area in the Guangzhou-Foshan region represented a compact, extremely integrated degree and a well-matched functional space.

Special Prosecutor
In the United States, a special counsel (formerly called special prosecutor or independent counsel) is a lawyer appointed to investigate, and potentially prosecute, a particular case of suspected wrongdoing for which a conflict of interest exists for the usual prosecuting authority. Other jurisdictions have similar systems. For example, the investigation of an allegation against a sitting president or attorney general might be handled by a special prosecutor rather than by an ordinary prosecutor who would otherwise be in the position of investigating their own superior. Investigations into other persons connected to the government but not in a position of direct authority over the prosecutor, such as cabinet secretaries or election campaigns, have also been handled by special prosecutors. While the most prominent special prosecutors have been those appointed since the 1870s to investigate presidents and those connected to them, the term can also be used to refer to any prosecutor appointed to avoid a conflict of interest or appearance thereof. The concept originates in state law: "state courts have traditionally appointed special prosecutors when the regular government attorney was disqualified from a case, whether for incapacitation or interest." Because district attorneys' offices work closely with police, some activists argue that cases of police misconduct at the state and local level should be handled by special prosecutors.
