Date rapists: Differential sexual socialization and relative deprivation

Deviant sexual behavior has often been portrayed as the consequence of the frustration of legitimate sexual outlets. This study of date rapists reveals that these men, as a result of a hypersexual socialization process, are sexually very active, successful, and aspiring. These exaggerated aspiration levels are seen as responsible for instituting a high degree of sexual frustration. This acute relative deprivation, it is hypothesized, is a significant process responsible for precipitating these rape episodes.     

Effects of cyproterone acetate on sexual arousal patterns of pedophiles

The antiandrogen treatment of sexual offenders has been shown to reduce the recidivism rate. The mechanism of action has been assumed to be through asexualization with its secondary effects on sexual behavior. This study shows that the mechanism may be more complex and may involve a differential effect on sexual arousal patterns. Treatment responses may differ in high and low plasma testosterone groups.     

Experience with pornography: Rapists,pedophiles, homosexuals,transsexuals, and controls

An interview designed to assess a respondent's experience with erotic material in photographs, films, and books, during adolescence and adulthood, was administered to convicted male rapists, pedophiles, homosexuals, transsexuals, heavy pornography users, and two nondeviant contrast groups. One nondeviant group was composed of whites matched for the sex offender group; the other was composed of ghetto and middle-class blacks. Adolescent exposure to erotica was significantly less for all deviant and offender groups compared to the nondeviants. During adulthood, the sex offenders and transsexuals continued to report less exposure to erotic stimuli than controls. The homosexuals and users, however, both report greater exposure during adulthood. As adolescents, the control group, rapists, and heavy users were excited to masturbate by the erotic materials more than the other groups. As adults, the controls and rapists showed a sharp decrease in being excited to masturbate to erotica while the users' rate remained high and the homosexuals' rate rose. Less than a quarter of the respondents in any group imitated sexual behavior seen in the erotic material immediately or shortly after its viewing. The hypothesis that extent of exposure during adolescence to erotica is positively associated with the later emergence of sexual pathology is not borne out by this study. The nondeviant, non-sex-offender groups sampled had had significantly greater exposure to erotic materials during adolescence than the deviants, convicted sex offenders, or heavy adult users of pornography.This study was carried out for the Commission on Obscenity and Pornography.Mr. Kant is also an attorney.     

Age differential mortality in Spain, 1900-1991

STUDY OBJECTIVE: To analyse the interindividual inequalities in mortality in Spain through the 20th century using the Gini coefficient, widely used as an income concentration index. DESIGN: Age mortality data were obtained from official publications of vital statistics and age and sex compositions were obtained from population census. The Gini coefficient was estimated. It can take values between 0 and 1. Zero represents the situation in which all subjects die at the same age, whereas when all but one subject dies at 25 the index reaches a figure of 1. MAIN RESULTS: In both men and women there was a trend to decrease age differential mortality (from 0.26 to 0.16 for men and from 0.26 to 0.12 for women). Nevertheless, transitory increases were produced in 1918 (influenza epidemic), and in the period of the Civil War of Spain, showing a more important increase in the mortality of young people than that of the elderly. A new increase was observed through the second half of eighties; it resulted from an AIDS epidemic and motor vehicle injuries. CONCLUSION: Inequalities in mortality in Spain have decreased through the 20th century.

 

     

Age of sexual debut among US adolescents

Background

This study examined gender and racial/ethnic differences in sexual debut.

Study Design

We analyzed 1999-2007 data from the Youth Risk Behavior Surveillance System (YRBSS), a cross-sectional, nationally representative survey of students in Grades 9-12 established by the Centers for Disease Control and Prevention. The Kaplan-Meier method was used to compute the probability of survival (not having become sexually active) at each year (age 12 through 17), and separate estimates were produced for each level of gender and racial/ethnic group.

Results

African-American males experienced sexual debut earlier than all other groups (all tests of significance at p<.001) and Asian males and females experienced sexual debut later than all groups (all tests of significance at p<.001). By their 17th birthday, the probability for sexual debut was less than 35% for Asians (females 28%, males 33%) and less than 60% for Caucasians (58% females, 53% males) and Hispanic females (59%). The probability for sexual debut by their 17th birthday was greatest for African Americans (74% females, 82% males) and Hispanic males (69%).

Conclusions

These results demonstrate a need for sexual education programs and policy to be sensitive to the roles of race and ethnicity in sexual debut.     

Aggression,impulsivity, plasma sex hormones,and biogenic amine turnover in a forensic population of rapists

The aim of the present study was to assess androgen plasma levels and biogenic amine metabolites in a sex-offender group as well as to investigate the relationship between the biological findings and the impulsive, aggressive, and suicidal profile of the offenders. Fifty-seven males convicted for rape and 25 normal males comprised the study sample. We found that although both testosterone levels and aggression-impulsivity scores were higher in the group of rapists, testosterone levels were not associated with the aggression and impulsivity scores. Nevertheless, aggression-impulsivity scores were clearly associated with luteinizing hormone levels. This association may indicate a hyperactive hypothalamic-pituitary-gonadal axis, possibly the result of a reduced serotonergic activity.     

Age and sexual culture among homosexually oriented males

It is here argued that the thesis has been overgeneralized that the culture of homosexually oriented males is heavily youth oriented. It is suggested that any youth orientedness is due to their largely single marital status rather than to sexual orientation. Utilizing data from 243 males from the Detroit area, several qualifications to the thesis of youth orientedness are indicated. It was found that a majority of males aged 18–24 prefer a male partner who is older, a majority of those aged 25–34 years prefer a same-age person, and 50% of those over 35 prefer a younger partner. These relationships were found to be especially strong among those segments of the sample who attend gay bars infrequently or who are of lower occupational levels. Also, higher occupational status was found to be associated with preference for the younger, independent of age. It is suggested that, because of the heterogeneity of the male homosexual community, the degree of emphasis of youth will be found to vary with social setting.This is a revision of a paper presented at the meetings of the Society for the Study of Social Problems, New York, New York, 1976.     

Age and disability: Explaining the wage differential

This paper estimates the level of explained and unexplained factors that contribute to the wage gap between workers with and without disabilities, providing benchmark estimates for Ireland. It separates out the confounding impact of productivity differences between disabled and non-disabled, by comparing wage differentials across three groups, disabled with limitations, disabled without limitations and non-disabled. Furthermore, data are analysed for the years 1995–2001 and two sub-samples pre and post 1998 allow us to decompose wage differentials before and after the Employment Equality Act 1998. Results are comparable to those of the UK and the unexplained component (upper bound of discrimination) is lower once we control for productivity differences. The lower bound level depends on the contribution of unobserved effects and the validity of the selection component in the decomposition model.     

Genital self-image as a component of sexual health: relationship between genital self-image,female sexual function,and quality of life measures

Thirty-one patients completed a Genital Self-Image Scale along with the Female Sexual Function Index (FSFI; Rosen et al., 2000), Sexual Distress Scale (Derogatis et al., 2001), Perceived Stress Scale (Cohen et al., 1983), Golombok Rust Inventory of Marital State (Rust et al., 1986) Questionnaire, and Beck's Depression Inventory (Beck et al., 1988). A positive genital self-image correlated negatively with amount of sexual distress and depression but not with marital state, perceived stress, or overall sexual function. A positive genital self-image was associated with higher desire but not with arousal, lubrication, orgasm, satisfaction, or absence of pain on the FSFI. Although not correlated directly with sexual function, genital self-image appears to be associated with parameters of the overall sexual experience.     

Age and sexual behavior of Japanese macaques (Macaca Fuscata)

The sexual behavior of the Arashiyama West troop, a natural semi-free-ranging troop of Japanese macaques, was studied during the 1973–1974 and 1974–1975 breeding seasons. The troop was transported intact from Japan to its current location in South Texas. There they have been free to move about in a 42.2-hectare electric fence enclosure. This report describes the relationships among age, aging, and sexual behavior. Males beginning at the age of 2.5 years were observed to series-mount estrous females in the double foot clasp mount position. Mounting in series in the double foot position is the normal pattern for Japanese macaque males. The ejaculation of semen with concomitant body movements indicative of orgasm begins at age 4.5 years at the earliest and continues until death. Males 4.5 and 5.5 years of age, sexually mature in the physiological sense, were not consistently sexually mature in the behavioral sense. The oldest male displayed traits that appear analogous to traits observed in aging human males. Females begin to experience estrus at 3.5 years of age. However, like pubescent males, pubescent females display behavioral patterns of sexual immaturity. The oldest female of the troop has remained sexually active. The attainment of sexual maturity by adulthood can be viewed as a learned process leading to efficiency and prowess, followed in old age by sexual involution.This study was partially supported by a University of Oregon Department of Anthropology PHS Biomedical Science Grant No. 50-262-1112.     

Early sexual experience as a factor in prostitution

Using the literature of the early sexual histories of normal women and two recent studies on the sexual histories of prostitutes, this article examines the pattern of early sexual experience among prostitutes and how it differs from that common to nonprostitute women. Some significant differences found between the samples of prostitutes and the samples of normal women were that the prostitute samples, on the whole, learned less about sex from parents and more from personal experiences, as children experienced more sexual advances by elders, were more victimized by incest, generally initiated sexual activity at a younger age, more often had no further relationship with their first coital partner, and experienced a higher incidence of rape. The analysis of these data on early sexual history concentrates on abusive sexual experiences such as incest and rape. The authors believe that an abusive sexual self-identity relates to the development of an adult female pattern of occupational deviance such as prostitution.Research funded through the Department of Health, Education, and Welfare, Public Health Service, Division of Research, National Institute on Drug Abuse, Grant No. 1 R01 DA 00918.     

Child sexual abuse as a risk factor for sexual risk behaviours among socially disadvantaged adolescents in Ibadan,Nigeria

This study documents the prevalence and association between child sexual abuse (CSA) and risky sexual behaviours among in-school adolescents in Ibadan, Nigeria. A cross-sectional study with 1,079 boys and 1,211 girls was conducted in 22 socially disadvantaged public secondary schools in a suburb of Ibadan, Nigeria. A 70-item sexual risk behaviour questionnaire was used to collect information on lifetime and current sexual experiences. Fifty-five per cent of students reported to have ever experienced at least one form of CSA. Thirty-six per cent reported a history of intra-family CSA, whereas 46% had experienced inter-family CSA. Five hundred and sixty-four (24.6%) of these adolescents were sexually active at the time of the study. There was a strong relationship between having ever experienced CSA and sexual risk behaviours: adolescent boys and girls with CSA were three-fold as likely not to use condom at last vaginal intercourse; thrice as likely to engage in casual sex with a partner known for a day; twice as likely to drink alcohol heavily before sex; thrice for tobacco smoking and three- fold for STD. Logistic regression shows that the relationship between CSA and non-use of condom at last vaginal intercourse remained after controlling for age, family type, parents staying together and hawking after school. We found that experiences of CSA may precipitate risky sexual behaviours in this population. A structural and educational approach towards educating both adolescents and parents of the possible effect of CSA to sexual risk behaviours is presented in this article.     

Age of sexual initiation and HIV-related behaviours: application of survival analysis

Previous studies have consistently suggested positive associations between early sexual initiation and subsequent risky sexual behaviours, HIV/STD infection, adolescent pregnancy and substance use. In the present study, survival curves for rural-to-urban migrants in China with and without HIV-related behaviours were analysed to determine (1) the risk of initiating sex at each ageand (2) the association between sexual initiation and HIV-related behaviours.     

Sister-sister incest as a manifestation of multigenerational sexual abuse

Incestuous child sexual abuse has received increasing attention recently, but relatively little attention has focused on the multigenerational dimensions of this problem. The case presented places incest into a multigenerational context and demonstrates how quickly family relationships may become eroticized in an uncommon form: between sisters.
