What is the theory?2 answersTheory is the formation of testable hypotheses and the basis for empirical work in science. It is not simply abstract or mathematical, but rather the process of generating hypotheses and testing them. The false dichotomy between theory and empirical work is highlighted, as models, mathematics, and methods provide the link between the two. Multiple hypotheses and auxiliary assumptions may be intertwined, making it difficult to determine which one is falsified by data. However, hypothesis formation and testing remain essential in science. The structure of theoretical papers and proposals can be understood within a tripartite parsing of science, consisting of theory, empirical work, and math/models/methods. Theory is central to organizational scholarship and is evaluated for research quality and contribution. Conceptual work, rather than empirical work, is the focus in this context. In communication studies, theory is approached from different perspectives, including theory as puzzle-solving or map-reading, and theory as puzzle-making or map-making. These perspectives reflect the subject-object schism and the creation of objects by subjects. Empirical theory refers to a set of empirical laws that govern specific phenomena, such as Mendelian Genetics and Newtonian Particle Mechanics. The idea that bilingualism has cognitive advantages beyond linguistic systems has gained interest, and research has scrutinized this concept. A critique of relevant research has raised important concerns.

What are the theoretical constructions of the Real Wai Fong Chua?
5 answers
The theoretical constructions of the Real by Wai Fong Chua involve a reconstruction of theorizing as a lived, social process, emphasizing that theory is grounded in assumptions about the Real, is both constructed by and constructs the Real, and that theory choice is inherent in the research process. Additionally, the interaction between classical and intuitionistic features in linear logic is described through category theory, where Girard's trips induce intuitionistic translations from a free *-autonomous category to a category with products. Furthermore, the Chu construction simplifies in a module category within a trivial Chu category, particularly in non-symmetric biclosed monoidal categories, and coalgebras have cofree objects for certain functors in accessible original categories.
What is the definition of the fat join the setting of category theory?
5 answers
In the realm of category theory, the concept of a fat join is introduced as a categorification of the classical join of two projective varieties, aligning with homological projective duality principles. This notion extends to the development of a theory of join and slices for strict $\infty$-categories, where a third category, termed the join, is associated with any pair of strict $\infty$-categories, respecting connected inductive limits and defining monoidal category structures. Furthermore, in the context of inverse categories modeling reversible functional programming, assuming countable joins leads to desirable properties for reversible recursion and algebraic $\omega$-compactness, offering insights into reversible recursion and addressing challenges in formulating recursive data types at the inverse category level.
