Question: Diplomacy and Upwords, are which specific type of entertainment?
Context: Diplomacy is a strategic board game created by Allan B. Calhamer in 1954 and released commercially in 1959.  Its main distinctions from most board wargames are its negotiation phases (players spend much of their time forming and betraying alliances with other players and forming beneficial strategies) and the absence of dice and other game elements that produce random effects.  Set in Europe before the beginning of World War I, "Diplomacy" is played by two to seven players, each controlling the armed forces of a major European power (or, with fewer players, multiple powers).  Each player aims to move his or her few starting units and defeat those of others to win possession of a majority of strategic cities and provinces marked as "supply centers" on the map; these supply centers allow players who control them to produce more units. In programming languages, ad hoc polymorphism is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, because a polymorphic function can denote a number of distinct and potentially heterogeneous implementations depending on the type of argument(s) to which it is applied.  It is also known as function overloading or operator overloading.  The term ad hoc in this context is not intended to be pejorative; it refers simply to the fact that this type of polymorphism is not a fundamental feature of the type system.  This is in contrast to parametric polymorphism, in which polymorphic functions are written without mention of any specific type, and can thus apply a single abstract implementation to any number of types in a transparent way.  This classification was introduced by Christopher Strachey in 1967. Anti-MAG Peripheral Neuropathy is a specific type of peripheral neuropathy in which the person’s own immune system attacks cells that are specific in maintaining a healthy nervous system.  As these cells are destroyed by antibodies, the nerve cells in the surrounding region begin to lose function and create many problems in both sensory and motor function.  Specifically, antibodies against myelin-associated glycoprotein (MAG) damage Schwann cells.  While the disorder occurs in only 10% of those afflicted with peripheral neuropathy, people afflicted have symptoms such as muscle weakness, sensory problems, and other motor deficits usually starting in the form of a tremor of the hands or trouble walking.  There are, however, multiple treatments that range from simple exercises in order to build strength to targeted drug treatments that have been shown to improve function in people with this type of peripheral neuropathy. In solid-state physics, heavy fermion materials are a specific type of intermetallic compound, containing elements with 4f or 5f electrons in unfilled electron bands.  Electrons are one type of fermion, and when they are found in such materials, they are sometimes referred to as heavy electrons.  Heavy fermion materials have a low-temperature specific heat whose linear term is up to 1000 times larger than the value expected from the free-electron theory.  The properties of the heavy fermion compounds often derive from the partly filled f-orbitals of rare-earth or actinide ions, which behave like localized magnetic moments.  The name "heavy fermion" comes from the fact that the fermion behaves as if it has an effective mass greater than its rest mass.  In the case of electrons, below a characteristic temperature (typically 10 K), the conduction electrons in these metallic compounds behave as if they had an effective mass up to 1000 times the free-electron mass.  This large effective mass is also reflected in a large contribution to the resistivity from electron-electron scattering via the Kadowaki Woods ratio.  Heavy fermion behavior has been found in a broad variety of states including metallic, superconducting, insulating and magnetic states.  Characteristic examples are CeCu, CeAl, CeCuSi, YbAl, UBe and UPt. Cultural diplomacy a type of public diplomacy and soft power that includes the "exchange of ideas, information, art and other aspects of culture among nations and their peoples in order to foster mutual understanding".  The purpose of cultural diplomacy is for the people of a foreign nation to develop an understanding of the nation's ideals and institutions in an effort to build broad support for economic and political goals.  In essence "cultural diplomacy reveals the soul of a nation", which in turn creates influence.  Though often overlooked, cultural diplomacy can and does play an important role in achieving national security efforts. Upwords (also branded as Scrabble Upwords in the United States and Canada, and Topwords Crucimaster, Betutorony, Palabras Arriba, Stapelwoord in other countries) is a board game invented by Elliot Rudell and originally published by the Milton Bradley Company, now a division of Hasbro.  The game remains under license to Hasbro by Rudell Design, LLC.  Upwords is similar to "Scrabble", or "Words With Friends", in that players build words using letter tiles on a gridded gameboard.  The point of difference is that in Upwords letters can be stacked on top of other letters already on the gameboard to create new words.  The higher the stack of letters, the more points are scored.  This typically makes words built in later turns of the game more valuable than earlier words, increasing play intensity and adding a level of strategy unique to Upwords.  The memorization of two-letter words is considered a useful skill in this game. Neutrophil swarming is a specific type of neutrophil migration behaviour characterised by a high coordination between neutrophils, clustering of neutrophils to the inflammation site and signalling to other neutrophils further away.  This specific type of migration rely on the production and secretion of LTB4 and on the use of integrins for neutrophil to stop at the cluster site. Uterine cancer or womb cancer is any type of cancer that emerges from the tissue of the uterus.  It can refer to several types of cancer, with cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries.  Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from developed countries.  Risk factors depend on specific type, but obesity, older age, and human papillomavirus infection add the greatest risk of developing uterine cancer.  Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop.  If caught early, most types of uterine cancer can be cured using surgical or medical methods.  When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of chemotherapy, radiation therapy, or surgery may be required. A star war was a decisive conflict between rival polities of the Maya civilization during the first millennium AD.  The term comes from a specific type of glyph used in the Maya script, which depicts a star showering the earth with liquid droplets, or a star over a shell.  It represents a verb but its phonemic value and specific meaning have not yet been deciphered.  The name "star war" was coined by the epigrapher Linda Schele to refer to the glyph, and by extension to the type of conflict that it indicates. Type I hypersensitivity (or immediate hypersensitivity) is an allergic reaction provoked by reexposure to a specific type of antigen referred to as an allergen.  Type I is not to be confused with type II, type III, or type IV hypersensitivities, nor is it to be confused with Type I Diabetes or Type I of any other disease or reaction.
