The mystique of first intercourse among college youth: The role of partners,contraceptive practices,and psychological reactions

The purpose of this study was to examine first sexual intercourse as it relates to gender differences regarding involvement in various sexual behaviors, the role of the partner, contraceptive practices, sexual guilt, and sexual satisfaction. An anonymous 155-item questionnaire was distributed to 304 never-married female and male undergraduate students at a Midwestern state university. Of these respondents, only those with sexual intercourse experience were included in this study. The overall mean age at first sexual intercourse was 17.7 years for females and 17.8 years for males. Although both males and females experienced first intercourse with older partners, females were more likely to be in committed relationships. First intercourse was characterized by a lack of contraceptive use, primarily due to lack of planning. Compared to males, females were less physiologically and psychologically satisfied with their first sexual intercourse experience.Support for data collection and coding was from the College of Arts and Sciences, University of Wisconsin—Eau Claire and for data analyses from Academic Computing Services, University of Wisconsin—Eau Claire. In addition, tables were produced by the Media Development Center with support from the School of Graduate Studies and Office of University Research, University of Wisconsin-Eau Claire.Received Ph.D. in human ecology from Michigan State University.

High-performance liquid chromatography-ultraviolet-visible spectroscopy-electrospray ionization mass spectrometry method for acrylic and polyester forensic fiber dye analysis

A critical point of comparison between a fiber collected from a crime scene and a fiber from a known source is the color. Fiber dye analysis using thin-layer chromatography or ultraviolet (UV)-visible (Vis) microspectrophotometry provides useful, although limited, data for comparison. High-performance liquid chromatography-electrospray ionization mass spectrometry (LC/MS) overcomes these limitations by integrating chromatography, ultraviolet-visible spectroscopy, and mass spectrometry into a single instrument. In order to evaluate the applicability of the LC/MS to forensic fiber dye analysis, a multi-stage chromatographic method using acidified water and acidified acetonitrile was developed that separated and identified a mixture of 15 basic and 13 disperse dye standards. The LC/MS also detected and analyzed dyes extracted from individual 0.5 cm acrylic and polyester fibers, demonstrating its applicability to this type of analysis. With regard to the analysis of disperse dyes in polyester fibers, the replacement of pyridine with acetonitrile in the extraction system allowed direct injection of the extracts into the LC/MS. The advantage of the LC/MS over other instrumental methods of textile dye analysis is demonstrated by the analysis and differentiation of three black acrylic fibers: two fibers had similar UV-Vis spectra but were differentiated with chromatography and two had similar UV-Vis spectra and chromatograms but were differentiated using the mass spectrometer.     

Psychiatric evaluations of sexual offenders

Ninety-five defendants charged with sexual offenses were evaluated in a forensic psychiatry clinic. Their psychiatric diagnoses, as well as social, demographic, and criminal characteristics, were studied. Almost half were found to have personality disorders, while one-fifth were given a diagnosis of schizophrenia, affective disorder, or an atypical psychosis. Surprisingly few were diagnosed as having a paraphilia.     

Cognitive-affective predictors of women's readiness to end domestic violence relationships

A model of women's readiness to terminate an abusive relationship was examined, using cognitive and emotional factors to predict readiness to change as conceptualized in the transtheoretical model. Factors previously identified in the domestic violence literature were selected to represent cognitive predictors (attribution and attachment style) and affective predictors (depression, hopelessness, anxiety, and anger) of readiness to end a domestic violence relationship. Responses by 85 female victims of intimate partner violence indicated that their overall readiness to terminate a relationship was predicted by a preoccupied attachment style and high emotional arousal. However, women's low level of anger predicted their precontemplation of change, the earliest stage of readiness, whereas internalizing emotional difficulties and preoccupation with their batterer predicted maintenance, the final stage of readiness to persist in their decision to leave their abuser. Implications of these findings for working with women considering leaving their partner are discussed.     

Estimating eyeball protrusion from body height, interpupillary distance, and inter-orbital distance in adults

Eyeball protrusion is one characteristic that must be assessed/predicted in craniofacial identification methods of skull-face superimposition and facial approximation. Previously it has been suggested that average exophthalmometry values, as measured on living individuals, should be used. However, it is unknown if proptosis prediction can be improved beyond the accuracy obtained when using mean values. Some authors have suggested that relationships between exophthalmos, height, interpupillary distance, and interorbital distance exist and it has been reported that these latter variables can be used to estimate eyeball projection. However, crucial tests are yet to be conducted. This study measures these variables and tests the accuracy of exophthalmometry means, a previously proposed prediction equation, and newly derived regression equations to determine which methods provide the best results. Data indicate that variation in exophthalmos is fairly small and as such prediction from other variables, like body height, are weak; thus, exophthalmometry means currently offer the best practical method of prediction. It should be noted that up to 2 mm error from either side of the mean is expected for 68% of cases.     

Placing the Crime Decline in Context: A Comment on Baumer and Wolff

This paper provides comments on the article by Baumer and Wolff. The key goal of these remarks is to stimulate thinking about the broader context of crime declines.
