source: Animality studies
text: Animality studies Animality studies is an emerging interdisciplinary academic field focused on the cultural study of animals and animality. It can be distinguished from animal studies and critical animal studies by its resistance to animal rights or animal welfare as an explicit justification for work in this field. According to Michael Lundblad, "If animal studies can be seen as work that explores representations of animality and related discourses with an emphasis on advocacy for nonhuman animals, animality studies becomes work that emphasizes the history of animality in relation to human cultural studies, without an explicit call for nonhuman advocacy."

source: Hahn series
text: Hahn series In mathematics, Hahn series (sometimes also known as Hahn–Mal'cev–Neumann series) are a type of formal infinite series. They are a generalization of Puiseux series (themselves a generalization of formal power series) and were first introduced by Hans Hahn in 1907 (and then further generalized by Anatoly Maltsev and Bernhard Neumann to a non-commutative setting). They allow for arbitrary exponents of the indeterminate so long as the set supporting them forms a well-ordered subset of the value group (typically formula_1 or formula_2). Hahn series were first introduced, as groups, in the course of the proof of the Hahn embedding theorem and then studied by him as fields in his approach to Hilbert's seventeenth problem.

source: Girl studies
text: Girl studies Girl studies, also known as girlhood studies, is an interdisciplinary academic field of study that is focused on girlhood and girls' culture that combines advocacy and the direct perspectives and thoughts of girls themselves. The field officially emerged in the 1990s after decades of falling under the broader field of women’s studies. Scholars within girl studies examine social and cultural elements of girlhood and move away from an adult-centered focus. Those working in the field of girl studies have studied it primarily in relation to other fields that include sociology, psychology, education, history, literary studies, media studies, and communication studies. Girl studies seeks to work directly with girls themselves in order to analyze their lives and understand the large societal forces at play within them. Scholars in girl studies also explore the connection the field has to women's studies, boyhood studies, and masculinity studies.

text: Madonna Studies Madonna Studies is a term which has been used to refer to a development of a field in several studios since late 1980s. One writer described the "institutionalization of a major subdivision of American media studies into Madonna studies". The field related to the study of and interpretation of the work of American pop musician Madonna using an interdisciplinary approach incorporating cultural studies and media studies. A notable compendium of essays titled "The Madonna Connection" was published in 1992. Controversy over this field of study stemmed from discussions over the intellectual worth of pursuing academic inquiry into a pop musician, with some arguing the field was nothing more than pop cultural commentary.
