differential association

- In criminology, Differential Association is a theory developed by Edwin Sutherland proposing that through interaction with others, individuals learn the values, attitudes, techniques, and motives for criminal behavior.

- Edwin Sutherland's term to indicate that associating with some groups results in learning an "excess of definitions" of social deviance, and, by extension, in a greater likelihood that one will become socially deviant (pg.343)

- A general theory of criminal behavior developed by E.H Sutherland. It attempts to explain the crime in terms of cultural transmission; crime is learned within primary groups whose members are criminally inclined.

definition

- A statement of the exact meaning of a word, esp. in a dictionary

- clarity of outline; "exercise had given his muscles superior definition"

- (define) specify: determine the essential quality of

- The action or process of defining something

- a concise explanation of the meaning of a word or phrase or symbol

- An exact statement or description of the nature, scope, or meaning of something

theory

- A set of principles on which the practice of an activity is based

- hypothesis: a tentative insight into the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena; "a scientific hypothesis that survives experimental testing becomes a scientific theory"; "he proposed a fresh theory of alkalis that later was

- a belief that can guide behavior; "the architect has a theory that more is less"; "they killed him on the theory that dead men tell no tales"

- An idea used to account for a situation or justify a course of action

- a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses"; "true in fact and theory"

- A supposition or a system of ideas intended to explain something, esp. one based on general principles independent of the thing to be explained

Ordinary Differential Equations: A Brief Eclectic Tour (Classroom Resource Materials)

For the instructor or student confronting an introductory course in ordinary differential equations there is a need for a brief guide to the key concepts in the subject. Important topics like stability, resonance, existence of periodic solutions, and the essential role of continuation of solutions are often engulfed in a sea of exercises in integration, linear algebra theory, computer programming and an overdose of series expansions. This book is intended as that guide. It is more conceptual than definitive and more light-hearted than pedagogic. It covers key topics and theoretical underpinnings that are necessary for the study of rich topics like nonlinear equations or stability theory. The author has included a great many illuminating examples and discussions that uncover the conceptual heart of the matter.

differential association theory definition

Differential geometry has a long, wonderful history. It has found relevance in areas ranging from machinery design to the classification of four-manifolds to the creation of theories of nature's fundamental forces to the study of DNA. This book studies the differential geometry of surfaces with the goal of helping students make the transition from the compartmentalized courses in a standard university curriculum to a type of mathematics that is a unified whole. It mixes together geometry, calculus, linear algebra, differential equations, complex variables, the calculus of variations, and notions from the sciences. Differential geometry is not just for mathematics majors. It is also for students in engineering and the sciences. The mix of ideas offer students the opportunity to visualize concepts through the use of computer algebra systems such as Maple. The book emphasizes that this visualization goes hand-in-hand with the understanding of the mathematics behind the computer construction. Students will not only see geodesics on surfaces, but they will also observe the effect that an abstract result such as the Clairaut relation can have on geodesics. Furthermore, the book shows how the equations of motion of particles constrained to surfaces are actually types of geodesics. The book is rich in results and exercises that form a continuous spectrum, from those that depend on calculation to proofs that are quite abstract.
