Middle classThe middle class refers to a class of people in the middle of a social hierarchy, often defined by occupation, income, education, or social status. The term has historically been associated with modernity, capitalism and political debate. Common definitions for the middle class range from the middle fifth of individuals on a nation's income ladder, to everyone but the poorest and wealthiest 20%. Theories like "Paradox of Interest" use decile groups and wealth distribution data to determine the size and wealth share of the middle class.
Soviet UnionThe Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR.
Professional–managerial classThe term professional–managerial class (PMC) refers to a social class within capitalism that, by controlling production processes through occupying a superior management position, is neither proletarian nor bourgeoisie. Conceived as "The New Class" by social scientists and critics such as Daniel Patrick Moynihan in the 1970s, this group of middle class professionals is distinguished from other social classes by their training and education, typically business qualifications and university degrees, with occupations thought to offer influence on society that would otherwise be available only to capital owners.
Recall (memory)Recall in memory refers to the mental process of retrieval of information from the past. Along with encoding and storage, it is one of the three core processes of memory. There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humans and animals. Two main theories of the process of recall are the two-stage theory and the theory of encoding specificity.
Hard problem of consciousnessThe hard problem of consciousness is a philosophical problem concerning why and how humans and other organisms have qualia, phenomenal consciousness, or subjective experiences. This is in contrast to the "easy problems" of explaining the physical systems that give humans and other animals the ability to discriminate, integrate information, perform behavioural functions, or provide behavioural reports, and so forth.
SelfIn philosophy, the self is the relationship of an individual’s own being, knowledge and values. Self relates the experiences of one's inner and outer living in presence. The first-person perspective distinguishes selfhood from personal identity. Whereas "identity" is (literally) sameness and may involve categorization and labeling, selfhood implies a first-person perspective and suggests potential uniqueness. Conversely, "person" is used as a third-person reference.
PriceA price is the (usually not negative) quantity of payment or compensation expected, required, or given by one party to another in return for goods or services. In some situations, the price of production has a different name. If the product is a "good" in the commercial exchange, the payment for this product will likely be called its "price". However, if the product is "service", there will be other possible names for this product's name.
Russian invasion of UkraineOn 24 February 2022, in an escalation of the Russo-Ukrainian War which began in 2014. The invasion has killed tens of thousands on both sides. Russian forces have been responsible for mass civilian casualties and for torturing captured Ukrainian soldiers. By June 2022, about 8 million Ukrainians had been internally displaced. More than 8.2 million had fled the country by May 2023, becoming Europe's largest refugee crisis since World War II. Extensive environmental damage, widely described as ecocide, contributed to food crises worldwide.

Republics of the Soviet UnionThe Republics of the Union of Soviet Socialist Republics or the Union Republics (Сою́зные Респу́блики) were national-based administrative units of the Union of Soviet Socialist Republics (USSR). The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russian Federation, Transcaucasian Federation, and Ukraine, by which they became its constituent republics of the Union of Soviet Socialist Republics (Soviet Union).
