Category theory : definitions and examples

Category theory was invented as an abstract language for describing certain structures and constructions which repeatedly occur in many branches of mathematics, such as topology, algebra, and logic. In recent years, it has found several applications in computer science, e.g., algebraic specification, type theory, and programming language semantics. In this paper, we collect definitions and examples of the basic concepts in category theory: categories, functors, natural transformations, universal properties, limits, and adjoints

Embracing Globalization: A Study of Factors Shaping Consumer Acceptance of Imported Products

Free trade as embraced by globalization is altering the world\u27s economies at an unprecedented pace. Yet, this inertia may be stymied by consumers who feel threatened by the changes in their domestic economies and by imported products.

The findings reveal that only consumer ethnocentrism has a strong association with opposition to imports. The other factors show some impact but in a more muted sense. Implications are presented
