Praxiology
In philosophy, praxeology or praxiology (; ) is the theory of human action, based on the notion that humans engage in purposeful behavior, contrary to reflexive behavior and other unintentional behavior. French social philosopher Alfred Espinas gave the term its modern meaning, and praxeology was developed independently by two principal groups: the Austrian school, led by Ludwig von Mises, and the Polish school, led by Tadeusz Kotarbiński. Origin and etymology Coinage of the word ''praxeology'' ('' praxéologie'') is often credited to Louis Bourdeau, the French author of a classification of the sciences, which he published in his ''Théorie des sciences: Plan de Science intégrale'' in 1882: However, the term was used at least once previously (with a slight spelling difference), in 1608, by Clemens Timpler in his ''Philosophiae practicae systema methodicum'': It was later mentioned by Robert Flint in 1904 in a review of Bourdeau's ''Théorie des sciences''.

1968 Polish Political Crisis
The Polish 1968 political crisis, also known in Poland as March 1968, Students' March, or March events ( pl, Marzec 1968; studencki Marzec; wydarzenia marcowe), was a series of major student, intellectual and other protests against the ruling Polish United Workers' Party of the Polish People's Republic.

It was also accompanied by mass emigration following an antisemitic (branded " anti-Zionist") campaign waged by the minister of internal affairs, General Mieczysław Moczar, with the approval of First Secretary Władysław Gomułka of the Polish United Workers' Party (PZPR). The protests overlapped with the events of the Prague Spring in neighboring Czechoslovakia – raising new hopes of democratic reforms among the intelligentsia.

Punched Card
A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record equipment, unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. The IBM 12-row/80-column punched card format came to dominate the industry. Many early digital computers used punched cards as the primary medium for input of both computer programs and Data (computing), data. While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still used punched cards to record votes. They also had a significant cultural impact.

Operations Research
Operations research ( en-GB, operational research) (U.S. Air Force Specialty Code: Operations Analysis), often shortened to the initialism OR, is a discipline that deals with the development and application of analytical methods to improve decision-making. It is considered to be a subfield of mathematical sciences. The term management science is occasionally used as a synonym. Employing techniques from other mathematical sciences, such as modeling, statistics, and optimization, operations research arrives at optimal or near-optimal solutions to decision-making problems. Because of its emphasis on practical applications, operations research has overlap with many other disciplines, notably industrial engineering. Operations research is often concerned with determining the extreme values of some real-world objective: the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost). Originating in military efforts before World War II, its techniques have grown to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polish United Workers' Party
The Polish United Workers' Party ( pl, Polska Zjednoczona Partia Robotnicza; ), commonly abbreviated to PZPR, was the communist party which ruled the Polish People's Republic as a one-party state from 1948 to 1989. The PZPR had led two other legally permitted subordinate minor parties together as the Front of National Unity and later Patriotic Movement for National Rebirth. Ideologically, it was based on the theories of Marxism-Leninism, with a strong emphasis on left-wing nationalism. The Polish United Workers' Party had total control over public institutions in the country as well as the Polish People's Army, the UB-SB security agencies, the Citizens' Militia (MO) police force and the media. The falsified 1947 Polish legislative election granted the far-left complete political authority in post-war Poland. The PZPR was founded forthwith in December 1948 through the unification of two previous political entities, the Polish Workers' Party (PPR) and the Polish Socialist Party ( ...
