Labeling and differential association: Towards a general social learning theory of crime and deviance

This study contends that components from two theories-labeling and differential association-should be incorporated into a general social learning perspective of crime and deviance. Data from waves one, two, and three of the National Youth Survey (n=1725) are used to test the proposed model. Results indicate that labeling effects are mediated by associations with delinquent peers when looking at a 24-item delinquency index. Theoretical implications and directions for future research are discussed.     

Inactivation of human immunodeficiency virus (HIV) by ionizing radiation in body fluids and serological evidence

A method to use ionizing radiation to inactivate HIV (Human Immunodeficiency Virus) in human body fluids was studied in an effort to reduce the risk of accidental infection to forensic science laboratory workers. Experiments conducted indicate that an X-ray absorbed dose of 25 krad was required to completely inactivate HIV. This does not alter forensically important constituents such as enzymes and proteins in body fluids. This method of inactivation of HIV cannot be used on body fluids which will be subjected to deoxyribonucleic acid (DNA) typing.     

Deoxyribonucleic acid (DNA) analysis by restriction fragment length polymorphisms of blood and other body fluid stains subjected to contamination and environmental insults.

Deoxyribonucleic acid (DNA) restriction fragment length polymorphism (RFLP) profile results were obtained from bloodstains and other body fluid stains subjected to mixture with other body fluids, environmental insults (sunlight and temperature), different substrates (cotton, nylon, blue denim, glass, aluminum, and wood), and contaminants (gasoline, bleach, sodium hydroxide, soil, motor oil, detergent, phosphate salt, glacial acetic acid, and microorganisms). Of the samples that produced profile results, all had profiles that were consistent with those of untreated control samples.
