This theory helps us understand that some criminal behavior is learned. Sutherland believed that there were basic principles of differential association and I will discuss them further. First is that “Criminal behavior is learned‚” which he means that it is not something genetically inherited from a family member

Discuss the differences between the absolute threshold and the differential threshold. Which is more important to marketers? Explain your answer. For each of these products—chocolate bars and bottles of expensive perfume—describe how marketers can apply their knowledge of differential threshold to packaging‚ pricing‚ and promotional claims during periods of (a) rising ingredient and materials costs and (b) increasing competition.

This study discusses compositions and methods of reducing or preventing back staining of indigo dyes on the weft yarn and pocket of denim garments. The dye‚ as it is removed from the denim material‚ post treatment with cellulase or by a conventional washing process may cause ‘back staining’ or ‘redeposition’ on the denim material; e.g : re-coloration of blue threads and blue coloration of white threads‚ resulting in less contrast between
