In Situ Identification of Semen Stains on Common Substrates via Raman Spectroscopy,,

The spectroscopic identification of body fluids in situ is a major objective in forensic science. This approach offers the confirmatory, nondestructive, rapid, and on‐scene identification of various body fluids. Although Raman spectroscopy has shown tremendous promise toward this goal in prior proof‐of‐concept experiments, a significant challenge which still remains is substrate interference. Here, an approach for detecting semen stains in situ on various substrates using Raman spectroscopy is explored. Simulated semen evidence was prepared on skin, glass, and various fabrics. Raman data were accumulated from stains without any pretreatment using a common confocal mapping spectrometer using 785 nm laser excitation. The results demonstrate that the spectroscopic interferences encountered by substrates can be reduced and eliminated using a combination of existing subtraction techniques and chemometric models. Heterogeneous substrates proved most challenging, however, automatic subtraction treatment, and location of fluid hotspots was able to elucidate a clear spectroscopic signature of semen in every instance.     

Prevalence and distribution of premarital aggression among couples applying for a marriage license

This study used a modified version of the Conflict Tactics Scale to examine the prevalence of premarital aggression in a community sample of husbands and wives. The sample consisted of 625 couples participating in a longitudinal study of marital functioning and alcohol use. Consistent with past studies, the overall prevalence rate of husband-to-wife premarital aggression was 35%. Sociodemographic variables were associated with premarital aggression, with differences emerging primarily with regard to moderate aggression rather than mild aggression. Further, factors such as race, education, social class, cohabitation, and presence of children were independently associated with premarital aggression. This study is one of the first to examine premarital aggression in a large, heterogeneous sample of young husbands and wives at the same stage of relationship development. Future analyses will examine the prevalence, frequency, and continuity of husband and wife aggression over the first year of marriage.
