    Lifetime histories of sexual and physical abuse have been associated with increased HIV-risk sexual behavior, and some studies have identified other variables associated with these relationships. However, there is a dearth of literature that has critically examined abuse histories and HIV-risk sexual behavior in relation to these other variables. Predictors of HIV-risk sexual behavior were analyzed among a sample of ex-offenders who were completing inpatient substance dependence treatment to identify factors related to increases in HIV-risk sexual behavior beyond that of abuse histories. Hierarchical linear regression was conducted to examine sociodemographic characteristics, recent substance use, and current psychiatric problem severity in addition to lifetime histories of sexual/physical abuse in a cross-sectional design. Gender, substance use, and psychiatric problem severity predicted increases in HIV-risk sexual behavior beyond what was predicted by abuse histories. Proportionately more women than men reported abuse histories. In addition, significantly more unprotected sexual than safer sexual practices were observed, but differences in these practices based on lifetime abuse histories and gender were not significant. Findings suggest recent substance use and current psychiatric problem severity are greater risk factors for HIV-risk sexual behavior than lifetime abuse histories among persons who have substance use disorders.

    This study draws on a life course perspective to evaluate in a sample of sexual minority women: (1) the relationship between age at reaching sexual identity milestones and risk of suicidal ideation, (2) developmental stages or stages of sexual identity development that represent greatest risk and (3) the relationship between age of reaching milestones and parental support. Research shows higher rates of suicidal ideation among sexual minority women than heterosexual women. Evidence suggests this is partly accounted for by risk factors including sexual identity development and parental support. However, it remains unclear whether there are stages of particularly high risk. This is a cross-sectional study. Data come from a prospective study of sexual minority women that used convenience and respondent-driven sampling methods. Using logistic regression, we examined associations among age at sexual identity developmental milestones, parental support and suicidal ideation in a large (N = 820), ethnically diverse sample of sexual minority women. Compared with women who first wondered about their sexual identity in adulthood, those who first wondered in early, middle or late adolescence had greater odds of lifetime suicidal ideation. Younger age at subsequent milestones (first decided or first disclosed) was not associated with heightened risk of suicidal ideation. Parental support was independently associated with suicidal ideation. Findings suggest that where one is in the process of identifying as a sexual minority may be more important than age in understanding risk of suicidal ideation in this population. As individuals come to accept and integrate their sexual minority identity risks associated with younger age diminish. Nurses and other healthcare providers who work with youth should routinely ask about sexual orientation and suicidal ideation and be aware that youth in the earliest stages of coming out as sexual minority may be at particularly high risk of

    The purpose of this study was to investigate the lifetime prevalence and characteristics of self-reported child sexual victimization and associations between sexual victimization and sociodemographic characteristics and victimological profiles in community adolescents in Spain. The Juvenile Victimization Questionnaire (Finkelhor, Hamby, Ormrod, & Turner, 2005) was applied to a sample of 1,105 community adolescents (M = 14.52 years, SD = 1.76). Experience of sexual victimization (with or without physical contact) was reported by 8.8% of the sample, at a mean age of 13 years old. Sexual victimization was more prevalent in girls (14.2%) and in older adolescents (10.6%). Offenders were mainly male (87.6%) and were mostly friends, neighbors, or schoolmates (52.6%). No injuries resulted from victimization (4.3%), although the percentage of penetration or attempted penetration was very high (30.6%). Only 9.3% of victims reported the incident to the police or the justice system. In regard to victimological profiles, sexual victims also experienced other forms of victimization (M = 7.16; SD = 3.39): boys reported more conventional crimes, peer and sibling victimization, and witnessing community violence than other victims, whereas sexually victimized girls reported more caregiver victimization and property crimes. Sexually victimized youth present a distinctive sociodemographic and victimological profile. Professionals need to be aware of these characteristics in order to conduct adequate prevention programs. We also need to assess a wide range of victimization experiences when treating sexual abuse victims in order to make adolescents less vulnerable to violence.

    Age at sexual debut and age gap between partners at debut are modifiable characteristics that may be related to risky sexual behaviors. Understanding any such relationships is a necessary first step toward strengthening risk interventions. Age at sexual debut and partner age gap were examined for 3,154 female and 2,713 male respondents to the 2011-2013 National Survey of Family Growth who first had intercourse before age 18. Multivariable logistic regression was used to assess associations between these measures and teenage parenthood and reporting a high lifetime number of partners (i.e., a number above the sample median). Females' odds of teenage parenthood were elevated if sexual debut occurred at ages 15-17 and involved a partner age gap of 3-4 years (odds ratio, 1.8) or more (2.0); they were reduced if debut occurred before age 15 and the gap was 3-4 years (0.8). Females' likelihood of reporting a high lifetime number of partners was negatively associated with age gap (0.4-0.7, depending on age at debut and length of age gap). Males' likelihood of reporting a large number of partners was positively associated with age gap if sexual debut was before age 15 and the gap was five or more years (1.7) or if debut was at ages 15-17 and involved a 3-4-year gap (2.0). Identifying the mechanisms underlying these associations could inform program design and implementation. Copyright © 2017 by the Guttmacher Institute.

    Stigma, discrimination and violence contribute to health disparities among sexual minorities. Lesbian, bisexual and queer (LBQ) women experience sexual violence at similar or higher rates than heterosexual women. Most research with LBQ women, however, has focused on measuring prevalence of sexual violence rather than its association with health outcomes, individual, social and structural factors. We conducted a cross-sectional online survey with LBQ women in Toronto, Canada. Multivariate logistic regression analyses were conducted to assess correlates of lifetime sexual assault (LSA). Almost half (42%) of participants (n = 415) reported experiences of LSA. Participants identifying as queer were more likely to have experienced LSA than those identifying as lesbian. When controlling for socio-demographic characteristics, experiencing LSA was associated with higher rates of depression, sexually transmitted infections (STIs), receiving an STI test, belief that healthcare providers were not comfortable with their LBQ sexual orientation, and sexual stigma (overall, perceived and enacted). A history of sexual violence was associated with lower: self-rated health, overall social support, family social support and self-esteem. This research highlights the salience of a social ecological framework to inform interventions for health promotion among LBQ women and to challenge sexual stigma and sexual violence.

    Although there is preliminary evidence that violence against women and children may be particularly prevalent in some Native American communities, associations between abuse and substance abuse, mental health problems, and suicide attempts have rarely been studied in this population. This study examined lifetime and current physical and sexual abuse among 30 Native American women. Nearly half had experienced physical and/or sexual abuse as children, over half were sexually abused at some time in their lives, and over three-fourths were abused by a partner. All but four women (87%) had experience physical or sexual abuse in their lifetime. Significant relationships were found among childhood abuse, substance abuse, and adult revictimization, and among cumulative lifetime abuse events, substance abuse, and depression. Further research is needed to examine abuse and relationships between abuse and health sequelae in Native American populations. An accelerated public health and community response is needed to address abuse issues in this community.

  13. The intersexual genetic correlation for lifetime fitness in the wild and its implications for sexual selection.

    Directory of Open Access Journals (Sweden)

    Jon E Brommer

    Full Text Available BACKGROUND: The genetic benefits of mate choice are limited by the degree to which male and female fitness are genetically correlated. If the intersexual correlation for fitness is small or negative, choosing a highly fit mate does not necessarily result in high fitness offspring. METHODOLOGY/PRINCIPAL FINDING: Using an animal-model approach on data from a pedigreed population of over 7,000 collared flycatchers (Ficedula albicollis, we estimate the intersexual genetic correlation in Lifetime Reproductive Success (LRS in a natural population to be negative in sign (-0.85+/-0.6. Simulations show this estimate to be robust in sign to the effects of extra-pair parentage. The genetic benefits in this population are further limited by a low level of genetic variation for fitness in males. CONCLUSIONS/SIGNIFICANCE: The potential for indirect sexual selection is nullified by sexual antagonistic fitness effects in this natural population. Our findings and the scarce evidence from other studies suggest that the intersexual genetic correlation for lifetime fitness may be very low in nature. We argue that this form of conflict can, in general, both constrain and maintain sexual selection, depending on the sex-specific additive genetic variances in lifetime fitness.

    To examine the relationship between cumulative exposure to various types of interpersonal violence throughout the life span and self-reported history of Chlamydia trachomatis (CT) diagnosis in a population-based sample of California women. This was a cross-sectional analysis of a population-based survey of California women aged 18-44 years (n = 3521). Participants reported their experience of multiple types of interpersonal violence: physical or sexual abuse in childhood or adulthood and intimate partner violence (IPV) in the past 12 months. Current posttraumatic stress disorder (PTSD) and depressive symptoms were also reported. Separate logistic regression models assessed the association between experiencing each type of interpersonal violence, as well as women's cumulative exposure to violence, and past CT diagnosis, adjusting for age, race/ethnicity, and poverty, as well as mental health problems. Six percent of women reported a past diagnosis of CT, and 40.8% reported experiencing at least one type of interpersonal violence in their lifetime. All types of violence were significantly associated with higher odds of having a past CT diagnosis even after controlling for sociodemographics. Women who reported experiencing four or more types of violence experiences had over five times the odds of reporting a lifetime CT diagnosis compared with women who never experienced interpersonal violence (adjusted odds ratio = 5.71, 95% CI 3.27-9.58). Current PTSD and depressive symptoms did not significantly affect the relationship between a woman's cumulative experience of violence and her risk of past CT diagnosis. There is a robust association between experiencing multiple forms of violence and having been diagnosed with CT. Women who seek treatment for sexually transmitted diseases (STDs), such as CT, should be assessed for their lifetime history of violence, especially violence in their current intimate relationships. Sexual risk reduction counseling may also be important

    Being non-heterosexual, particularly bisexual, is associated with high rates of engagement in NSSI amongst young adults. The goal of the present study was to determine if parenting practices, specifically parental monitoring, and sexual orientation moderate engagement with NSSI. Undergraduates (N = 1,353) completed a survey on sexual orientation, non-suicidal self-injury (NSSI) acts, and multiple aspects of perceived parental monitoring during high school. Moderation analyses revealed that most facets of parental monitoring were similarly negatively correlated with NSSI for both individuals whose sexual orientation where nearly, or entirely, gay and heterosexual youth. Youth who were neither exclusively heterosexual nor exclusively gay (mixed sexual orientation) reported the most NSSI acts, and no facet of parental monitoring predicted reduced NSSI acts for this group. While previous literature shows that many aspects of parental monitoring may be protective against engagement in health risk behaviors, the present study adds to these findings that similar aspects are negatively associated with self-injurious behavior for some, but not all, individuals. More research is needed to better understand the causes of increased NSSI for individuals with a mixed sexual orientation.

  17. Lifetime mating opportunities and male mating behaviour in sexually cannibalistic praying mantids.

    I examined the number of lifetime mating opportunities and mating behaviour of males in two sexually cannibalistic species, the Mediterranean, Iris oratoria, and bordered, Stagmomantis limbata, praying mantids (Mantodea: Mantidae). Two approaches estimated the number of lifetime mating opportunities: direct observations of intersexual encounters in the field, and an encounter model. I collected behavioural observations, together with ecological data for use in the model, over three field seasons. The ecological data included an assessment of the feeding condition of S. limbata females in nature; the females fed at a level comparable to females maintained on an abundant diet in the laboratory. As for the number of mating opportunities, individual males of both species encountered two or more females, as predicted by the model. I observed no male, however, in more than one copulation. This result could reflect individual variation in the times and places of sexual activity or an actual low number of mating opportunities in the field. Furthermore, a higher percentage of I. oratoria males encountered two or more females than S. limbata males, as the model indicates. Fewer mating opportunities could lead to greater selection upon S. limbata males to ensure paternity at each mating, which can explain the longer copulation times observed for S. limbata males. I considered two hypotheses about male behaviour in light of the number of lifetime encounters with females: male suicide and male reduction of the risk of cannibalism. Behavioural observations do not strongly support male suicide in either species. Certain male behaviours, such as the nature of copulatory position and, in captivity, mounting females from the rear, are consistent with the idea that males behave so as to reduce the probability that they are cannibalized during intersexual encounters. Moreover, male I. oratoria preferentially mount well-fed, fecund females in captivity. Taken together, these results

    This study examined the sexual behaviour and self-reported incidence of STDs of White and Chinese American young people in a nationally representative US sample. 10,419 White and 340 self-identified Chinese American young people in grade 7 through 12 were selected from the National Longitudinal Study of Adolescent Health. Prevalence of sex initiation, ever having casual sex partners, number of lifetime sex partners, age of first sexual intercourse, and history of self-reported STD diagnoses were compared between these two groups. Chinese American young people reported significantly lower rates of sexual intercourse than Whites. Among sexually active young people, Chinese Americans were also less likely to report non-regular sexual partners and to report having a lower number of such sexual partners in the past year. There was no difference in self-reported STDs between the two groups. Ever having been romantically involved, older age, not living in a two-parent household, having more relaxed attitudes about sex, and reported substance use were associated with a higher likelihood of sexual intercourse in both groups. Being native-born was not associated with patterns of sexual behaviour among Chinese Americans.

    The 3-year accelerated aging study of the SAVY-4000 O-ring shows very little evidence of significant degradation to samples subjected to aggressive elevated temperature and radiation conditions. Whole container thermal aging studies followed by helium leakage testing and compression set measurements were used to establish an estimate for a failure criterion for O-ring compression set of ≥65 %. The whole container aging studies further show that the air flow and efficiency functions of the filter do not degrade significantly after thermal aging. However, the degradation of the water resistant function leads to water penetration failure after four months at 210°C, but does not cause failure after 10 months at 120°C (130°C is the maximum operating temperature for the PTFE membrane). The thermal aging data for O-ring compression set do not meet the assumptions of standard time-temperature superposition analysis for accelerated aging studies. Instead, the data suggest that multiple degradation mechanisms are operative, with a reversible mechanism operative at low aging temperatures and an irreversible mechanism dominating at high aging temperatures. To distinguish between these mechanisms, we have measured compression set after allowing the sample to physically relax, thereby minimizing the effect of the reversible mechanism. The resulting data were analyzed using two distinct mathematical methods to obtain a lifetime estimate based on chemical degradation alone. Both methods support a lifetime estimate of greater than 150 years at 80°C. Although the role of the reversible mechanism is not fully understood, it is clear that the contribution to the total compression set is small in comparison to that due to the chemical degradation mechanism. To better understand the chemical degradation mechanism, thermally aged O-ring samples have been characterized by Fourier Transform Infrared (FTIR), Electron Paramagnetic Resonance (EPR), Gel Permeation Chromatography (GPC

    Sexual aggression as committed by women has been the target of little empirical research and is still regarded as a myth by many people. The aim of this study was to evaluate the psychosexual profile of young and educated women reporting sexual aggression against men. This is a cross-sectional study; a total of 260 female college students answered to an online survey. Among them, 93 (35.8%) reported having committed some form of sexual aggression against men: 46.2% of sexually aggressive women fell into the category of sexual coercion, 34.1% fell into the category of sexual abuse, and 19.8% reported having used physical force. Findings revealed that sexually aggressive women reported significantly higher levels of sociosexuality, sexual fantasies of dominance and submission, sexual compulsivity, sexual excitation, and sexual inhibition due to the threat of sexual performance failure. Data are expected to affect prevention strategies for a relevant yet understudied social concern.

    Prevalence of sexual victimization among lesbian, gay, bisexual, transgender, and queer (LGBTQ) persons is frequently found to be higher than the prevalence reported by their heterosexual peers. Transgender individuals are often included solely as part of larger LGBTQ research samples, potentially obfuscating differences between sexual orientation and gender identity. In this study, the authors examined sexual assault/rape in a large convenience sample of LGBTQ adults (N = 1,124) by respondents' gender identity (cisgender, transgender) to determine whether differences exist in lifetime prevalence of sexual assault/rape and subsequent police reporting. Findings indicate transgender individuals report having experienced sexual assault/rape more than twice as frequently as cisgender LGBQ individuals. Authors found no statistically significant difference in reporting sexual violence to police. Implications for research and practice are discussed.

    The decay of the free neutron into a proton, electron and antineutrino is the prototype of the semi-leptonic weak decay and plays a key role in particle physics and astrophysics. Nowadays, the accuracy achieved is limited by systematic errors, mainly caused by anomalous losses during storage of neutrons (ultracold neutrons) in material vessels. The magnetic storage of neutrons aims to avoid these systematic limitations and is expected to reach an accuracy of 0.1-0.3 s in the lifetime of the neutron. In this talk, the magnetic spectrometer tau-SPECT is presented, which uses a combination of magnetic multipole fields for radial storage and the field configuration of the superconducting aSPECT magnet for longitudinal storage of ultracold neutrons. This storage experiment benefits greatly from the new ultracold neutron source at the pulsable TRIGA reactor Mainz. The talk gives an overview of the experimental status: Proton detection system and adiabatic fast passages device.

    Although the Internet has become a forum for making sexual contacts, and has been associated with increased sexually transmitted infection (STI) transmission, we have little information of history of STIs in Internet-based samples. The Internet behaviours that are associated with STI acquisition are poorly understood. We analysed STI histories reported by 904 Swedish men and 931 Swedish women who responded to an Internet-based survey on sexual behaviour in 2002: 16.6% of men and 22.5% of women reported a lifetime history of STIs, with Chlamydia being the most common for both genders. 3% of men and 5% of women who reported an STI, indicated that they had had more than one. Sources of the STI, where known, were Internet-acquired partners in only 3% of cases. There were no differences between men and women with or without an STI history regarding the kind of online sexual activities they engaged in, how they found sexual material online, and the reasons they engage in sexual activities. These rates are similar to those reported in a national random study of sexuality in Sweden. Contrary to prior research, these results suggest no relationship between STI and specific Internet characteristics usage patterns. These data suggest that the Internet is not yet a major source of STIs in Swedish men and women. Given these STI histories, the Internet may be a useful medium to include in STI prevention efforts.

    National, epidemiological data that provide lifetime rates of psychological, physical, and sexual adolescent data abuse (ADA) perpetration and victimization within the same sample of youth are lacking. To address this gap, data from 1058 randomly selected U.S. youth, 14-21 years old, surveyed online in 2011 and/or 2012, were weighted to be nationally representative and analyzed. In addition to reporting prevalence rates, we also examined the overlap of the six types of ADA queried. Results suggested that ADA was commonly reported by both male and female youth. Half (51 %) of female youth and 43 % of male youth reported victimization of at least one of the three types of ADA. Half (50 %) of female youth and 35 % of male youth reported at least one type of ADA perpetration. More male youth reported sexual ADA perpetration than female youth. More female youth reported perpetration of psychological and physical ADA and more reported psychological victimization than male youth. Rates were similar across race and ethnicity, but increased with age. This increase may have been because older youth spent longer time in relationships than younger youth, or perhaps because older youth were developmentally more likely than younger youth to be in abusive relationships. Many youth reported being both perpetrators and victims and/or involved in multiple forms of ADA across their dating history. Together, these findings suggested that interventions should acknowledge that youth may play multiple roles in abusive dyads. Understanding the overlap among ADA within the same as well as across multiple relationships will be invaluable to future interventions aiming to disrupt and prevent ADA.

    Phenotypic differences among individuals are often linked to differential survival and mating success. Quantifying the relative influence of genetic and environmental variation on phenotype allows evolutionary biologists to make predictions about the potential for a given trait to respond to selection and various aspects of environmental variation. In particular, the environment individuals experience during early development can have lasting effects on phenotype later in life. Here, we used a natural full-sib/half-sib design as well as within-individual longitudinal analyses to examine genetic and various environmental influences on plumage color. We find that variation in melanin-based plumage color – a trait known to influence mating success in adult North American barn swallows (Hirundo rustica erythrogaster) – is influenced by both genetics and aspects of the developmental environment, including variation due to the maternal phenotype and the nest environment. Within individuals, nestling color is predictive of adult color. Accordingly, these early environmental influences are relevant to the sexually selected plumage color variation in adults. Early environmental conditions appear to have important lifelong implications for individual reproductive performance through sexual signal development in barn swallows. Our results indicate that feather color variation conveys information about developmental conditions and maternal care alleles to potential mates in North American barn swallows. Melanin-based colors are used for sexual signaling in many organisms, and our study suggests that these signals may be more sensitive to environmental variation than previously thought.

    2016-09-01

    Systematic research on sexual development in adolescents with autism spectrum disorder (ASD) remains scant, notwithstanding the often-suggested relation between ASD, atypical, and even sexually offensive behaviours. This study compared follow-up data related to lifetime sexual experience (LTSE) in a homogeneous group of adolescent boys with ASD (n = 30), aged 16-20, with a matched group of boys in the general population (n = 60). Most boys in the ASD and control groups reported masturbation and having experienced an orgasm. The proportion of boys with ASD that had no partnered sexual experience was larger than in the control group. This difference was mostly explained by significantly fewer boys with ASD, compared with controls, who reported experience with kissing and petting; no significant differences emerged relating to more intimate partnered sexual experiences. The results suggest the existence of a subgroup of boys who have not (yet) entered the arena of partnered sexual experiences-a finding in line with research in adult samples. There were no differences relating to sexual abuse or coercion. Exploration of the partnered experiences revealed a variety of types of partners, mostly of comparable age. Several boys with ASD had not anticipated their sexual debut. Although they felt ready for it, some boys reported regret afterward. The hypothesised sexual developmental trajectories are subject to further research, but the sexual experience in this sample and the assumed developmental differences indicate the need for early, attuned, and comprehensive sexuality-related education and communication.

    There has been relatively little research on the degree to which measures of lifetime history of substance abuse add to the prediction of risk based on actuarial measures alone among sexual offenders. This issue is of relevance in that a history of substance abuse is related to relapse to substance using behavior. Furthermore, substance use has…

    The impact of sexual fantasies in future risk and treatment response among sexual offenders has long been known. However, as we develop objective self-report measures of sexual fantasies, response bias is becoming an increasing concern. In examining a sample of institutionalized sex offenders, the present study suggests that offenders' responses on these measures are prone to response bias, the bias does not negate their associations with other self-report measures of sexual deviance, and relationship of their sexual fantasies does not appear to relate to actual behavioral indications. Clinical and research implications for these findings are discussed.

    Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM") patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. In total, 32.9% (n = 23) MtF reported a change in sexual orientation in contrast to 22.2% (n = 10) FtM transsexual persons (p = 0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p = 0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05). In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

    Assessing sexual risk is critical for human immunodeficiency virus (HIV) and sexually transmitted infection (STI) prevention with adolescents. This article compares sexual risk reports from two self-administered instruments, a standard survey and a sexual health history calendar (SHHC), among racially diverse youth (n = 232) ages 14 to 21 seeking services at a public health clinic. Agreement between methods was assessed using Lin's concordance correlation coefficients (CCC) and Bland-Altman plots. Lin's CCC showed poor to moderate agreement between instruments on reports of sexual partners in the past 3 (0.47), 6 (0.55), and 12 (0.49) months. While individual sexual partner questions were refused a total of 179 times on the survey, youth reported having sexual partners during the same time period on the SHHC in most (77.1%) of these instances. Poor agreement was also found for condom use frequency (CCC = 0.17), with youth's frequency of condom use on the SHHC differing from that reported on the survey for more than half (55.6%) of the months they were sexually active. While lack of objective sexual behavior measures limits conclusions about the accuracy of reports, the ways in which youth's responses varied across instruments may offer insight into the complexity of adolescent sexual risk taking as well as have important implications for development of HIV/STI preventive interventions.

    This study examined correlates of the discordance between sexual behavior self-reports and Incident Sexually Transmitted Infections. African American adolescent females (N = 964) from four U.S. cities were recruited for an HIV/STI prevention trial. Self-reported sexual behaviors, demographics, and hypothesized psychosocial antecedents of sexual risk behavior were collected at baseline, 6-, 12-, and 18-month follow-up assessments. Urine specimens were collected and tested for three prevalent STIs (chlamydia, gonorrhea, trichomonas) at each assessment. Seventeen percent of participants with a laboratory-confirmed STI reported either lifetime abstinence or recent abstinence from vaginal sex (discordant self-report). Lower STI knowledge, belief that fewer peers were engaging in sex, and belief that more peers will wait until marriage to have sex were associated with discordant reports. Discordance between self-reported abstinence and incident STIs was marked among African American female adolescents. Lack of STI knowledge and sexual behavior peer norms may result in underreporting of sexual behaviors.

    2013-01-01

    This article reports parental experiences of legally reporting child sexual abuse in Tanzania. Based on in-depth interviews, four types of sexual abuse incidents are portrayed. Each evokes different reactions from parents and the community. An incident characterized as the innocent child was associated with a determination to seek justice. The forced-sex youth elicited feelings of parental betrayal of their child. The consenting curious youth resulted in uncertainty of how to proceed, while the transactional-sex youth evoked a sense of parental powerlessness to control the child because of low economic status. Differentiating between types of sexual abuse incidents may increase awareness of the complexities of child sexual abuse reporting. Education on laws regulating sexual offenses and a functional national child protection system are needed to address child sexual abuse complexities and safeguard the rights of children in Tanzania.

    Female-to-male trans masculine adults who have sex with cisgender (non-transgender) males (TMSM) represent an understudied population in relation to HIV/sexually transmitted infection (STI) risk. This study examined the role of syndemic conditions and social gender affirmation processes (living full-time in one's identified gender) in potentiating sexual risk among TMSM adults in Massachusetts, US. Cross-sectional data were restricted to TMSM who reported lifetime sexual behaviour with a cisgender male (n = 173; mean age = 29.4, SD = 9.6; 18.5% people of colour; 93.1% non-heterosexual identity; 56.1% hormones/surgery). Sexual risk outcomes were: lifetime STI diagnoses, three or more sexual partners in the previous six months, and condomless anal/vaginal sex at last encounter with a cisgender male. Age- and survey mode-adjusted logistic regression models regressed sexual risk outcomes on the main effect of syndemics (six indicators summed: binge drinking, substance use, depression, anxiety, childhood abuse, intimate partner violence), followed by the interaction of syndemics and social gender affirmation. Syndemics were associated with increased odds of all sexual risk indicators (adjusted odds ratios [aORs] = 1.32-1.55; p Social gender affirmation moderated the association between syndemics and condomless anal/vaginal sex at last encounter with a cisgender male (p socially affirmed their gender (aOR = 1.79; 95% CI = 1.42-2.25; p socially gender affirmed as for cisgender MSM.

    There were three specific objectives of this research. First, a short time acceptance test for EF fittings that is fundamentally related to the long time field performance was to be developed that would permit the use of existing lifetime forecasting procedures to quantify joint lifetimes. The second objective was to determine the effects of the various design and installation variables such as power input, heating time, cool-down time, initial pipe-coupler clearance and ambient temperature on the service performance. The third objective was to investigate and quantify the effects of surface preparation and cleanliness on joint integrity. Four final reports have been published to cover the diversified technology developed in this research.

  13. The role of ethnicity, sexual attitudes, and sexual behavior in sexual revictimization during the transition to emerging adulthood.

    2014-01-01

    An experience of child sexual abuse (CSA) substantially increases women's risk of adult sexual assault (ASA), but the mechanisms underlying this relationship are unclear. Previous research often has not examined the full range of ASA experiences or included the influence of ethnicity, sexual behavior, and sexual attitudes on CSA and severity of ASA. The current study utilized path analysis to explore the relationships among ethnicity, sexual attitudes, number of lifetime sexual partners, CSA, and severity of ASA in emerging adult women. Results indicated a significant relationship between CSA and more severe ASA that was partially explained by having more lifetime sexual partners. Additionally, European American women, relative to Hispanic women, reported more severe victimization, which was fully explained by more positive attitudes toward casual sex and having more lifetime sexual partners. These results have implications in the design and implementation of universal and selective prevention programs aimed at reducing ASA and revictimization among emerging adult women. © The Author(s) 2014.

  14. Self-reported sexual desire in homosexual men and women predicts preferences for sexually dimorphic facial cues.

    Welling, Lisa L M; Singh, Kevin; Puts, David A; Jones, Benedict C; Burriss, Robert P

    2013-07-01

    Recent studies investigating the relationship between self-reported sexual desire and attraction to same- and opposite-sex individuals have found that homosexual men's sexual desire is positively correlated with their self-reported attraction to own-sex individuals only, while homosexual women's sexual desire is positively correlated with their self-reported attraction to both men and women. These data have been interpreted as evidence that sexual desire strengthens men's pre-existing (i.e., dominant) sexual behaviors and strengthens women's sexual behaviors in general. Here we show that homosexual men's (n = 106) scores on the Sexual Desire Inventory-2 (SDI-2) were positively correlated with their preferences for exaggerated sex-typical shape cues in own-sex, but not opposite-sex, faces. Contrary to the hypothesis that sexual desire strengthens women's preferences for sexual dimorphism generally, homosexual women's (n = 83) SDI-2 scores were positively correlated with their preferences for exaggerated sex-typical shape cues in opposite-sex faces only. Together with previous research in heterosexual subjects, our findings support the proposal that sexual desire increases the incidence of existing sexual behaviors in homosexual and heterosexual men, and increases the incidence of sexual responses more generally in heterosexual women, although not necessarily in homosexual women.

  15. The association of sexual interest and sexual behaviors among adolescent women: A daily diary perspective

    Theoretical and empirical linkages of adult women’s sexual interest and sexual behaviors are relatively well-established, but few data address similar issues in adolescent women. This paper reviews data from published reports of associations of adolescent women’s sexual interest and various sexual behaviors. All of the papers reported data collected from a single longitudinal cohort of young women. The primary source of data collection was daily diaries, allowing close temporal pairing of sexual interest with sexual behaviors. Young women’s sexual interest on a given day was consistently and independently associated with sexual activity on that day, whether the behavior was first lifetime coitus, coitus, fellatio, cunnilingus, anal intercourse, or coitus during menses. We also found no evidence of influence of hormonal contraceptives on young women’s sexual interest. Taken together, these data demonstrate the relevance of sexual interest as a key factor in young women’s sexuality and sexual behavior. PMID:21397605

    Sexual coercion may affect the sexual experiences of sexual minority women differently. Women (n=445) aged 18 to 71 years (Mean=30.38) answered an online survey on sexual orientation, lifetime coercion, and sexual history. Sexual minority women (45.8%, n=204) were more likely to report having been coerced into unwanted sexual behavior (56.5%) than heterosexual women (44.8 %; p=0.010). Coerced sexual minority women reported earlier ages of initiation into performing oral sex (p=0.016), penile-vaginal (p=0.024), and penile-anal (p=0.027) intercourse. In multiple logistic regression models, currently being in a partnered relationship was the sole factor related to lifetime engagement in penile-vaginal intercourse and receiving oral sex from partners. Having at least a graduate degree was the only characteristic related to engagement in lifetime penile-anal intercourse. Sexual coercion was not related to any lifetime sexual behavior outcomes. The nature of sexual initiation and coercion should be explored further among sexual minority women, with the goal of incorporating their experiences into prevention and treatment initiatives.

    Consistent evidence exists for sexual interest in children in nonclinical/nonforensic male populations. However, prevalences for community men's self-reported sexual interest in children have been based on indiscriminate definitions including postpubescent individuals, age-restricted samples, and/or small convenience samples. The present research assessed men's self-reported sexual interest in children (including child prostitution and child sex tourism) on the community level and examined the link between strictly defined sexual fantasies and behaviors involving prepubescent children. In an online survey of 8,718 German men, 4.1% reported sexual fantasies involving prepubescent children, 3.2% reported sexual offending against prepubescent children, and 0.1% reported a pedophilic sexual preference. Sexual fantasies involving prepubescent children were positively related to sexual offending against prepubescent children. Sexual interest in children was associated with subjectively perceived need for therapeutic help. In contrast to findings from forensic samples, men who reported child pornography use exclusively were identified as a subgroup differing from contact sexual offenders against prepubescent children and men who reported both child pornography use and contact sexual offenses against prepubescent children. The empirical link between child-related sexual fantasies and sexual victimization of prepubescent children and high levels of subjective distress from this inclination underscore the importance of evidence-based child sexual abuse prevention approaches in the community. Findings are discussed in terms of their relation to pedophilic disorder.

    Conclusions: Screening using an empirically validated self‐report instrument indicates that there is a high prevalence of reported sexual dysfunction among recently deployed veterans. Analyses indicated that there are specific characteristics associated with both overall self‐reported sexual dysfunction and specific subtypes of sexual dysfunction. Active assessment of specific aspects of sexual dysfunction concerns may allow providers to identify and implement more precise sexual functioning interventions.

    We present a detailed report of the method, setup, analysis and results of a precision measurement of the positive muon lifetime. The experiment was conducted at the Paul Scherrer Institute using a time-structured, nearly 100%-polarized, surface muon beam and a segmented, fast-timing, plastic scintillator array. The measurement employed two target arrangements; a magnetized ferromagnetic target with a ~4 kG internal magnetic field and a crystal quartz target in a 130 G external magnetic field. Approximately 1.6 x 10^{12} positrons were accumulated and together the data yield a muon lifetime of tau_{mu}(MuLan) = 2196980.3(2.2) ps (1.0 ppm), thirty times more precise than previous generations of lifetime experiments. The lifetime measurement yields the most accurate value of the Fermi constant G_F (MuLan) = 1.1663787(6) x 10^{-5} GeV^{-2} (0.5 ppm). It also enables new precision studies of weak interactions via lifetime measurements of muonic atoms.

    2010-01-01

    Full Text Available The objective of this report is to describe an urban county hospital human immunodeficiency virus (HIV infection prevention protocol offering prophylactic combination antiretroviral medications to female victims of sexual assault. A retrospective chart review was conducted from June, 2007 through June, 2008 of 151 women who were prescribed antiretroviral prophylaxis by protocol. All women receiving HIV prophylaxis initially screened HIV seronegative. Of the 58 women who reported taking any HIV prophylaxis, 36 (62% were HIV screened at 12 and/or 24 weeks and none had HIV seroconverted. Although the initiation of an HIV post exposure prophylaxis protocol for sexual assault in a county hospital population is feasible, patient follow-up for counseling and HIV serostatus evaluation is an identified barrier

  8. Gender differences in the risk of HIV infection among persons reporting abstinence, monogamy, and multiple sexual partners in northern Tanzania.

    Directory of Open Access Journals (Sweden)

    Keren Z Landman

    Full Text Available BACKGROUND: Monogamy, together with abstinence, partner reduction, and condom use, is widely advocated as a key behavioral strategy to prevent HIV infection in sub-Saharan Africa. We examined the association between the number of sexual partners and the risk of HIV seropositivity among men and women presenting for HIV voluntary counseling and testing (VCT in northern Tanzania. METHODOLOGY/ PRINCIPAL FINDINGS: Clients presenting for HIV VCT at a community-based AIDS service organization in Moshi, Tanzania were surveyed between November 2003 and December 2007. Data on sociodemographic characteristics, reasons for testing, sexual behaviors, and symptoms were collected. Men and women were categorized by number of lifetime sexual partners, and rates of seropositivity were reported by category. Factors associated with HIV seropositivity among monogamous males and females were identified by a multivariate logistic regression model. Of 6,549 clients, 3,607 (55% were female, and the median age was 30 years (IQR 24-40. 939 (25% females and 293 (10% males (p<0.0001 were HIV seropositive. Among 1,244 (34% monogamous females and 423 (14% monogamous males, the risk of HIV infection was 19% and 4%, respectively (p<0.0001. The risk increased monotonically with additional partners up to 45% (p<0.001 and 15% (p<0.001 for women and men, respectively with 5 or more partners. In multivariate analysis, HIV seropositivity among monogamous women was most strongly associated with age (p<0.0001, lower education (p<0.004, and reporting a partner with other partners (p = 0.015. Only age was a significant risk factor for monogamous men (p = 0.0004. INTERPRETATION: Among women presenting for VCT, the number of partners is strongly associated with rates of seropositivity; however, even women reporting lifetime monogamy have a high risk for HIV infection. Partner reduction should be coupled with efforts to place tools in the hands of sexually active women to reduce their risk

  9. Police Officer Schema of Sexual Assault Reports: Real Rape, Ambiguous Cases, and False Reports.

    2016-03-01

    While extensive research has studied sexual assault reporting behaviors and described negative experiences with the criminal justice system among victim-survivors, fewer studies have explored police officer attitudes, knowledge, and thought processes that may affect victims' perceptions of negative interactions and unsatisfactory outcomes within reported sexual assault cases. This study explores police officer understanding of the definition of sexual assault and characteristics that influence their perceptions and response. Ten police officers were interviewed within one police department in a midsized city in the Great Lakes region. The study uses a modified grounded theory approach. Findings suggest that officers employ distinct schema of reported sexual assaults. Case characteristics, perceived credibility of the victim, and types of evidence formed categorizations of false reports, ambiguous cases, and legitimate sexual assaults. Police officers describe the ways in which perceptions of the case may or may not influence the response and point to areas for improvement within police procedure. The study findings provide insight into recommendations for improved police interviewing and response to reported sexual assaults.

    This study characterized sexual orientation identities and sexual fluidity in attractions in a community-based sample of self-identified transgender and gender-nonconforming adults in Massachusetts. Participants were recruited in 2013 using bimodel methods (online and in person) to complete a one-time, Web-based quantitative survey that included questions about sexual orientation identity and sexual fluidity. Multivariable logistic regression models estimated adjusted risk ratios (aRRs) and 95% confidence intervals (95% CIs) to examine the correlates of self-reported changes in attractions ever in lifetime among the whole sample (n = 452) and after transition among those who reported social gender transition (n = 205). The sample endorsed diverse sexual orientation identities: 42.7% queer, 19.0% other nonbinary, 15.7% bisexual, 12.2% straight, and 10.4% gay/lesbian. Overall, 58.2% reported having experienced changes in sexual attractions in their lifetime. In adjusted models, trans masculine individuals were more likely than trans feminine individuals to report sexual fluidity in their lifetime (aRR = 1.69; 95% CI = 1.34, 2.12). Among those who transitioned, 64.6% reported a change in attractions posttransition, and trans masculine individuals were less likely than trans feminine individuals to report sexual fluidity (aRR = 0.44; 95% CI = 0.28, 0.69). Heterogeneity of sexual orientation identities and sexual fluidity in attractions are the norm rather than the exception among gender minority people.

    Full Text Available Sexual deviance in human refers to abnormal sexual expression. Though it is very difficult to exactly say what is normal or abnormal in sexual relationships, some sexual behaviors are clearly documented as abnormal in our society. Paraphilias or perversions are sexual stimuli or acts that are deviations from normal sexual behaviors, but are necessary for some individual’s to experience arousal and orgasm. Here we discuss abnormal sexual deviations in a young married male who presented with just feelings of guilt and without any psychosocial dysfunctions because of his uncommon sexual perversions.

    Non-nuclear organics, while not yet regarded to be at risk, figure in a large percentage of Significant Findings Investigations. Further, early application of advanced lifetime, compatibility, and base-lining assessments for LEP replacement materials and emerging materials for the Reliable Replacement Warhead (RRW) provides data for rational material choices. This task is currently assessing the chemical and mechanical characteristics of a variety of weapon organics prioritized by the risk-consequence of material aging. The majority of effort to date has been dedicated to silicone elastomer components known to lose their load resistance with age, with additional effort dedicated to urethane adhesives. This fiscal year, we have focused on initial aging studies of UNI620-3, a candidate replacement material for DC745U, and Adiprene (LW520). Aging studies of S5455, originally scheduled for testing in FY05, were postponed until FY07. We have initiated aging studies on these materials by employing accelerated aging tests with exposure to Co-60 {gamma}-radiation and elevated temperatures and studying their mechanical properties using a variety of analytical tools including nuclear magnetic resonance (NMR), dynamic mechanical analysis (DMA), and differential scanning calorimetry (DSC). Additionally, we have investigated aging signatures present in parts returned from surveillance as well as initiated long and short term stress relaxation studies for a thorough understanding of compression set occurring in silicone elastomers components. Additional investigations of aging processes in fluoropolymer binders and the combined effects of radiation and tensile set on silicone pads were performed. Finally, we have used temperature programmed desorption (TPD) studies to significantly improve the accuracy of our H{sub 2}O outgassing model in comparison with last year through the use of the isoconversion technique as well as to measure the equilibrium vapor pressure of hydrogenated

    AIM: To obtain current data about child sexual abuse in Denmark and to assess abused children's own perception of early sexual experiences, which are unlawful according to the Danish Penal Code. METHODS: Multimedia computer-based self-administered questionnaires (CASI) were completed by a national...... representative sample of 15-16-y-olds. Child sexual abuse was defined according to the penal code and measured by questions defining specific sexual activities, the relationship between the older person and the child, and the youth's own perception of the incident. RESULTS: Among 5829 respondents, 11% reported...... unlawful sexual experiences, 7% of boys and 16% of girls. Only 1% of boys and 4% of girls felt that they "definitely" or "maybe" had been sexually abused. CONCLUSION: A relatively high percentage of Danish adolescents have early, unlawful sexual experiences. However, young people's own perception of sexual...

    2014-07-01

    The aim of the present study was to investigate the prevalence of not reporting sexual attraction in the past year and its associations with factors related to partner relations as well as sexuality-related characteristics in a population-based sample of Finnish twins. The present study was based on a total of 3,540 participants (1,304 men and 2,236 women) aged 33-43 years. A total of 19 men and 73 women reported complete absence of sexual interest in women or men during the past year. Older age was associated with absence of sexual interest in the past year in women, but not men. Individuals who reported absence of sexual interest in the past year were more likely than individuals who reported sexual interest to be single, but those who were in a relationship did not express more dissatisfaction with their relationships. Individuals who reported absence of sexual interest in the past year had had fewer sexual partners and reported less experience of sexual behavior in childhood. Women who reported no sexual interest in the past year, but who were nevertheless sexually active, reported higher frequencies of sexual dysfunctions than matched controls. No significant differences regarding the tendency to fake orgasm were found between the sexually active individuals who reported absence of sexual interest in the past year and the group of matched controls. The present study suggests that absence of sexual interest may be a lifelong phenomenon which does not necessarily affect relationship satisfaction, but is associated with variation in sexual behaviors.

  17. Police interviews of sexual assault reporters: do attitudes matter?

    Science.gov (United States)

    Rich, Karen; Seffrin, Patrick

    2012-01-01

    Sexual assault is underreported in the United States. Survivors are often reluctant to make police reports for various reasons; one is fear of revictimization by criminal justice professionals. Conversely, police officers often lack skills for interviewing crime victims. Posttraumatic stress reactions among victims can exacerbate the problem. Although some victims prefer female interviewers, it is not known whether they are more skilled. A sample of 429 police officers completed a written survey testing their rape myth acceptance and knowledge of how to interview rape reporters. A significant relationship between rape myth acceptance and interviewing skill was discovered. Although officer gender was related to interviewing skill, the effect was mediated by rape myth acceptance. Specific officer behaviors related to high rape myth acceptance were identified. Implications for selection of police to conduct victim interviews were discussed.

    2016-07-10

    Although the physical and psychological consequences of sexual violence can be severe, many victims do not report the violence to the police force. The current study examined the characteristics and the post-decisional attitude of the non-reporting sexual violence victims. In total, 287 victims of sexual violence completed an anonymous online questionnaire that assessed characteristics of the violence, whether or not the crime was reported, reasons for not reporting, and aspects that would have convinced non-reporters to report in retrospect. Eighty percent of the victims did not report the most recent sexual violence incident to the police (n = 229). Nevertheless, 65% of the non-reporting victims (n = 148) in retrospect would have reported to the police ("potential reporters"). Specific reasons for non-reporting and incident characteristics appear to relate to the post-decision attitude of non-reporting victims of sexual violence. "Lack of evidence" and "feelings of shame, guilt, and other emotions" appear to be more frequently mentioned by potential reporters as reasons for their decision to not report as compared with the definitive non-reporters. Likewise, being raped or sexually assaulted is predictive of potential reporting. Our findings are useful for policy makers to develop strategies to increase reporting rates of sexual violence victims.

  1. Validity of Self-reported Sexual Behavior Among Adolescents: Where Do We Go from Here?

    Science.gov (United States)

    DiClemente, Ralph J

    2016-01-01

    Adolescents have high rates of sexually transmitted infections (STIs). Adolescents consuming alcohol and using drugs have markedly greater HIV/STI risk and are a priority population for intervention. Accurate measurement of sexual risk behavior is critical for understanding individual's risk for HIV/STI, transmission dynamics of HIV/STI, and evaluating the efficacy of interventions designed reduce HIV/STI risk. However, significant challenges to accurately measuring adolescents' self-reported sexual behavior are well-documented. Recent advances in microbiology, such as the use of less invasive specimen collection for DNA assays, can assist researchers in more accurately measuring adolescents' sexual risk behavior. However, the majority of studies of adolescents' sexual risk rely solely on self-reported behavior; therefore, methods to improve the validity of adolescents' self-reported sexual behavior are needed. In addition, integrating biologic measures to complement self-reported measures are recommended, when appropriate and feasible.

    Mollborn, Stefanie; Everett, Bethany

    2010-07-01

    Using the National Longitudinal Study of Adolescent Health, factors associated with incongruence between parents' and adolescents' reports of teens' sexual experience were investigated, and the consequences of inaccurate parental knowledge for adolescents' subsequent sexual behaviors were explored. Most parents of virgins accurately reported teens' lack of experience, but most parents of teens who had had sex provided inaccurate reports. Binary logistic regression analyses showed that many adolescent-, parent-, and family-level factors predicted the accuracy of parents' reports. Parents' accurate knowledge of their teens' sexual experience was not found to be consistently beneficial for teens' subsequent sexual outcomes. Rather, parents' expectations about teens' sexual experience created a self-fulfilling prophecy, with teens' subsequent sexual outcomes conforming to parents' expectations. These findings suggest that research on parent-teen communication about sex needs to consider the expectations being expressed, as well as the information being exchanged.

  5. Clinical report--the evaluation of sexual behaviors in children.

    Science.gov (United States)

    Kellogg, Nancy D

    2009-09-01

    Most children will engage in sexual behaviors at some time during childhood. These behaviors may be normal but can be confusing and concerning to parents or disruptive or intrusive to others. Knowledge of age-appropriate sexual behaviors that vary with situational and environmental factors can assist the clinician in differentiating normal sexual behaviors from sexual behavior problems. Most situations that involve sexual behaviors in young children do not require child protective services intervention; for behaviors that are age-appropriate and transient, the pediatrician may provide guidance in supervision and monitoring of the behavior. If the behavior is intrusive, hurtful, and/or age-inappropriate, a more comprehensive assessment is warranted. Some children with sexual behavior problems may reside or have resided in homes characterized by inconsistent parenting, violence, abuse, or neglect and may require more immediate intervention and referrals.

    2008-01-01

    Sex and drinking go hand-in-hand in Western societies. Men also tend to report more sexual disinhibition under the influence of alcohol and drugs than women. At a vacation resort,we conducted a survey of young men and women regarding self-reported alcohol-related sexual disinhibition (ARSD), and we...... administered the Drinking-Induced Disinhibition Scale (DIDS). We made several comparisons of behavioral patterns using the ARSD scale of the DIDS for each gender: kissing or having sex vs. no sexual contact, or having sex versus kissing or no contact. In general, men reported more ARSD than women. Men who...... reported either kissing or having sex the night before reported significantly more ARSD than men not reporting either kissing or having sex. Women who had had sex the night before reported more ARSD than women who had either kissed or not reported any sexual contact on the night before, but women who had...

  12. The Influence of Trauma History and Relationship Power on Latinas' Sexual Risk for HIV/STIs.

    Science.gov (United States)

    Randolph, Mary E; Gamble, Heather L; Buscemi, Joanna

    2011-01-01

    A community sample of Latinas completed surveys that included measures of sexual abuse and intimate partner violence history, relationship power, negotiating power regarding condom use, perceived HIV/STI risk of sexual partner, and sexual behavior. Over half of the women reported a history of intimate partner violence in the past year and/or sexual abuse in their lifetime. Intimate partner violence was correlated with lower overall sexual relationship power scores, while sexual abuse was correlated with lower condom use negotiating power. More extensive intimate partner violence had the strongest association with higher HIV/STI risk, controlling for relationship status, sexual abuse, and relationship power.

  13. Disparities in Social Health by Sexual Orientation and the Etiologic Role of Self-Reported Discrimination.

    Science.gov (United States)

    Doyle, David Matthew; Molix, Lisa

    2016-08-01

    Some past work indicates that sexual minorities may experience impairments in social health, or the perceived and actual availability and quality of one's social relationships, relative to heterosexuals; however, research has been limited in many ways. Furthermore, it is important to investigate etiological factors that may be associated with these disparities, such as self-reported discrimination. The current work tested whether sexual minority adults in the United States reported less positive social health (i.e., loneliness, friendship strain, familial strain, and social capital) relative to heterosexuals and whether self-reported discrimination accounted for these disparities. Participants for the current study (N = 579) were recruited via Amazon's Mechanical Turk, including 365 self-identified heterosexuals (105 women) and 214 sexual minorities (103 women). Consistent with hypotheses, sexual minorities reported impaired social health relative to heterosexuals, with divergent patterns emerging by sexual orientation subgroup (which were generally consistent across sexes). Additionally, self-reported discrimination accounted for disparities across three of four indicators of social health. These findings suggest that sexual minorities may face obstacles related to prejudice and discrimination that impair the functioning of their relationships and overall social health. Moreover, because social health is closely related to psychological and physical health, remediating disparities in social relationships may be necessary to address other health disparities based upon sexual orientation. Expanding upon these results, implications for efforts to build resilience among sexual minorities are discussed.

    2015-01-01

    To determine the extent of sexual victimization in four groups of Spanish adolescents based on their own reports. An observational, cross-sectional, multicenter study was conducted. Sexual victimization was assessed by seven questions included in the Juvenile Victimization Questionnaire. The samples were composed of 1,105 adolescents (mean age [M]=14.52, standard deviation [SD]=1.76) from seven secondary schools; 149 adolescents (M=14.28; SD=1.45) from 14 child and adolescent mental health centers; 129 adolescents (M=14.59, SD=1.62) institutionalized in 18 long-term (78.3%) and short-term (21.7%) residential centers belonging to the child protection system; and 101 adolescents (M=16.08, SD=0.99) recruited from three detention centers (77.2%) and five open regime teams or follow-up services for court orders for minors not requiring loss of freedom (22.8%). The extent of lifetime sexual victimization ranged from 14.7% of the adolescents in the community sample to 23.5% of youths attended in mental health services, 35.6% of youths involved in the juvenile justice system, and 36.4% of children protected by the child welfare system. Most of the victims were female, the only exception being the group of male victims from the juvenile justice system. Sexual victimization of children is widespread in Spain and its distribution differs depending on the group of children under study. Copyright © 2015 SESPAS. Published by Elsevier Espana.

    Blanchard-Dallaire, Claudia; Hébert, Martine

    2014-01-01

    This study aimed to explore the social relationships of child victims of sexual abuse using both self-reports and teachers' ratings. Participants were 93 child victims of sexual abuse and a comparison group of 75 nonvictims. Teachers' assessments revealed that sexually abused children displayed greater social skill problems compared to same-age, nonabused peers and were more likely to display social difficulties nearing clinical levels. Analyses indicated that sexually abused children presented lower levels of interpersonal trust in people surrounding them yet a marginally higher level of trust in peers compared to nonabused children. Sense of loneliness and feeling different from peers did not differ between groups.

    2014-12-01

    Sexual violence is prevalent nationally and contributes to psychopathology in the general population. Despite elevated traumatic event exposure among economically disadvantaged urban-dwelling African-Americans, there is insufficient information on lifetime sexual violence exposure and associated psychopathology in this population. In 2008-2009, 1,306 African-Americans from a Detroit household probability sample reported on lifetime rape and sexual assault and past-month and lifetime posttraumatic stress disorder (PTSD). Lifetime sexual violence prevalence was 26.3 % for women and 5.1 % for men. Relative to non-victims, sexual violence victims: reported more other traumatic events; had 4 times greater unadjusted odds of past-month and lifetime PTSD; had 1.6 times greater adjusted odds of lifetime PTSD only after controlling for other traumatic events. Sexual violence was associated with increased risk for lifetime PTSD and exposure to other traumas. Findings highlight a need to screen for sexual violence and PTSD among urban African-Americans.

    2017-08-01

    A traditionally marginalized subset of couples engage in consensual nonmonogamy (CNM: open marriage, polyamory, swinging, etc.) or alternative sexualities, such as kink or bondage/discipline, dominance/submission, and sadism/masochism. Nonmonogamous and sexually diverse individuals often experience discrimination or stigma in various domains of professional services, including mental healthcare. These cases require knowledge, skills, and awareness to provide culturally sensitive care, which is often called "kink aware therapy" or "poly-friendly therapy" within alternative sexuality communities. This article explores one application of a kink-focused and CNM-focused therapeutic framework for working with a couple who is exploring nontraditional sexualities. This case incorporates evidence-based clinical practice and identifies the limitations and significant gaps in the empirical research literature. © 2017 Wiley Periodicals, Inc.

    2016-02-01

    Full Text Available Introduction: Under current HIV transmission mechanisms operating in Vietnam, women are seen as victims of their male partners. Having multiple sexual partners is one of the well-known risk factors for HIV infection. However, little is known about women's risky sexual behaviour and their vulnerability to HIV in Vietnam. This study aims to explore association between early sexual initiation and the number of lifetime sexual partners in Vietnamese women. Although the Vietnamese culture is socially conservative in this area, identifying women's risky sexual behaviour is important for the protection of women at risk of HIV and other sexually transmitted diseases. Design: A total of 8,791 women, who reported having had sexual intercourse, were included in this analysis of data from the 2011 Multiple Indicator Cluster Survey in Vietnam. Data were collected using two-stage strata sampling, first at the national level and second across six geographical regions (n=8,791. Multivariable logistic regressions describe association between early initiation of a sexual activity and lifetime multiple sexual partners. Results: Early sexual intercourse was significantly associated with having lifetime multiple sexual partners. Women who were aged 19 or younger at first sexual intercourse were over five times more likely to have multiple sexual partners, compared with women whose first sexual intercourse was after marriage; aged 10–14 years (OR=5.9; 95% CI=1.9–18.8 at first intercourse; and aged 15–19 years (OR=5.4; 95% CI=4.0–7.2 at first intercourse. There was significant association with having multiple sexual partners for women of lower household wealth and urban residence, but the association with educational attainment was not strong. Conclusions: The study results call for health and education policies to encourage the postponement of early sexual activity in young Vietnamese women as protection against risky sexual behaviour later in life.

  9. QSO Lifetimes

    Martini, P

    2003-01-01

    The QSO lifetime t_Q is one of the most fundamental quantities for understanding black hole and QSO evolution, yet it remains uncertain by several orders of magnitude. If t_Q is long, then only a small fraction of galaxies went through a luminous QSO phase. In contrast, a short lifetime would require most galaxies today to have undergone a QSO phase in their youth. The current best estimates or constraints on t_Q from black hole demographics and the radiative properties of QSOs vary from at least 10^6 to 10^8 years. This broad range still allows both possibilities: that QSOs were either a rare or a common stage of galaxy evolution. These constraints also do not rule out the possibility that QSO activity is episodic, with individual active periods much shorter than the total active lifetime. In the next few years a variety of additional observational constraints on the lifetimes of QSOs will become available, including clustering measurements and the proximity effect. These new constraints can potentially dete...

    We report a fluorescence lifetime imaging technique that uses the time integrated response to a periodic optical excitation, eliminating the need for time resolution in detection. A Dirac pulse train of variable period is used to probe the frequency response of the total fluorescence per pulse leading to a frequency roll-off that is dependent on the relaxation rate of the fluorophores. The technique is validated by demonstrating wide-field, realtime, lifetime imaging of the endocytosis of inorganic quantum dots by a cancer cell line. Surface charging of the dots in the intra-cellular environment produces a switch in the fluorescence lifetime from approximately 40 ns to technique offers lifetime based imaging at video rates with standard CCD cameras and has application in probing millisecond cell dynamics and in high throughput imaging assays.

    2012-11-01

    Full Text Available Introduction: Obsessive-compulsive disorder (OCD, even if the patient’s obsession content is not related to sexuality, may be a problem in the sexual lives of individuals. In this article, sexual function in obsessive compulsive disorder patients is discussed based on an OCD case. Case: Male 36 years old and female 32 years old couple. Man had complaints of lack of control of ejaculation and woman had complaints of lack of orgasm. Man was diagnosed with premature ejaculation and woman was diagnosed with aversion and anorgasmia according to DSM-IV (Diagnostic and Statistical Manual Of Mental Disorders criteria. During therapy, the female patient was diagnosed with OCD as well. Loss of control was not acceptable to the patient. Thus she was avoiding from exhilarating stimuli. After cognitive restructuring of her evaluations about control, sex therapy was continued. At the end of the therapy the avoidance of the patient disappeared and anorgasmia was treated and ejeculation time of the male patient was 15 minutes. Conclusion: Sexual dysfunction is a common problem in patients with OCD. Patient may have avoidance that may adversely affect her sexuality. If a patient has avoidance about sexuality, the reason of this avoidance may or may not be the usual and expected thought content like avoidance of contamination. The evaluations of OCD patients about control may also adversely affect their sexuallity. The thought leading to avoidance behavior, may vary from patient to patient. However, to identify these thoughts with cognitive interventions and work with them will improve.the patient.

    2008-01-01

    Sexual medicine healthcare professionals, who do not normally examine men and women with psychiatric disorders, need to be aware that those with psychiatric disorders can and do present with sexual medicine problems. In particular, psychiatric individuals may present with a variety of delusions including those that have sexual content or sexual implications. The rare disorder of reverse delusional misidentification syndrome may be encountered in schizophrenic patients and may be best managed by the combined team effort of a sexual medicine specialist and psychiatrist. To report a case study that reiterates the assessment and sexual medicine management of a female with sexual dysfunction who believed she was transforming into a male. Case report of a woman who attended an outpatient clinic in an academic medical center. A 60-year-old woman with a history of paranoid schizophrenia presented to a gynecologist for ovarian cancer screening. Evaluation revealed complaints that the patient's ovaries were testes that produced sperm and her clitoris was a penis capable of erection and ejaculation. Gynecological examination revealed only atrophic vaginitis. The patient was treated with local minimally absorbed vaginal estrogens and referred for psychological assessment and counseling. Psychotropic medication compliance was encouraged, weekly psychotherapy was continued, and delusional symptoms were minimized. Sexual medicine healthcare providers should be prepared to manage sex health concerns of men and women with psychiatric disorders, including delusional misidentification syndrome, in conjunction with a psychiatrist.

    To compare changes in self-reported sexual orientation of women living in states with any recognition of same-sex relationships (e.g., hospital visitation, domestic partnerships) with those of women living in states without such recognition. We calculated the likelihood of women in the Nurses' Health Study II (n = 69 790) changing their reported sexual orientation between 1995 and 2009. We used data from the Nurses' Health Study II and found that living in a state with same-sex relationship recognition was associated with changing one's reported sexual orientation, particularly from heterosexual to sexual minority. Individuals who reported being heterosexual in 1995 were 30% more likely to report a minority orientation (i.e., bisexual or lesbian) in 2009 (risk ratio = 1.30; 95% confidence interval = 1.05, 1.61) if they lived in a state with any recognition of same-sex relationships compared with those who lived in a state without such recognition. Policies recognizing same-sex relationships may encourage women to report a sexual minority orientation. Future research is needed to clarify how other social and legal policies may affect sexual orientation self-reports.

    2003-01-01

    Urethral masturbation and sexual disinhibition as manifestations of behavioral and psychological symptoms of dementia (BPSD) are described in a 90-year-old patient who repeatedly self-inserted foreign bodies into his urethra. A diagnosis was made of late onset sexual disinhibition and hypersexuality in a patient with Dementia of the Alzheimer Type. Significant reduction of his sexual behavior was achieved with low doses of haloperidol. Similar symptoms are noted in Pick's disease, other fronto-temporal lesions, mania and following a seizure or treatment of Parkinson's disease, and have been described as Kluver-Busy-type. Clinicians should consider this diagnosis when investigating dysuria, cystitis, haematuria and urinary tract infections even in the very old.

    2017-02-01

    Guided by theoretical (Brooks-Gunn & Paikoff, 1997) and empirical work (Horne & Zimmer-Gembeck, 2005), this cross-sectional study examined whether sexual well-being (sexual self-acceptance, importance of mutual consent, importance of safe sex) was associated with life satisfaction among Mexican adolescents, and whether these associations were moderated by gender, age, and familism. Mexican adolescents (54% girls, 72% middle schoolers, 30% sexually active) completed surveys. Findings indicated that a greater belief in the importance of safe sex was associated with higher levels of life satisfaction. Greater sexual self-acceptance was associated with life satisfaction, and familism moderated this association. This association was stronger among adolescents who reported low familism. This study contributes to the understanding of sexual adolescent well-being and psychological adjustment in Mexico, an understudied cultural context.

    This study characterized sexual orientation identities and sexual fluidity in attractions in a community-based sample of self-identified transgender and gender nonconforming adults in Massachusetts. Participants were recruited in 2013 using bi-model methods (online and in-person) to complete a one-time web-based quantitative survey that included questions about sexual orientation identity and sexual fluidity. Multivariable logistic regression models estimated Adjusted Risk Ratios (aRR) and 95% Confidence Intervals (95% CI) to examine the correlates of self-reported changes in attractions ever in lifetime among the whole sample (n=452) and after transition among those who reported social gender transition (n=205). The sample endorsed diverse sexual orientation identities: 42.7% queer, 19.0% other non-binary, 15.7% bisexual, 12.2% straight, 10.4% gay/lesbian. Overall, 58.2% reported having experienced changes in sexual attractions in their lifetime. In adjusted models, trans masculine individuals were more likely than trans feminine individuals to report sexual fluidity in their lifetime (aRR=1.69; 95% CI=1.34, 2.12). Among those who transitioned, 64.6% reported a change in attractions post-transition and trans masculine individuals were less likely than trans feminine individuals to report sexual fluidity (aRR=0.44; 95% CI=0.28, 0.69). Heterogeneity of sexual orientation identities and sexual fluidity in attractions are the norm rather than the exception among gender minority people. PMID:26156113

    Questionnaire development, validation and completion. Develop comprehensive survey of sexuality issues including validated self-report versions of the International Spinal Cord Injury male sexual function and female sexual and reproductive function basic data sets (SR-iSCI-sexual function). People with spinal cord damage (SCD) living in the community, Australia from August 2013 to June 2014. An iterative process involving rehabilitation medicine clinicians, a nurse specialising in sexuality issues in SCD and people with SCD who developed a comprehensive survey that included the SR-iSCI-sexual function. Participants recruitment through spinal rehabilitation review clinic and community organisations that support people with SCD. Surveys completed by 154 people. Most were male (n=101, 65.6%). Respondents' median age was 50 years (interquartile range (IQR) 38-58), and they were a median of 10 years (IQR 4-20) after the onset of SCD. Sexual problems unrelated to SCD were reported by 12 (8%) respondents, and 114 (n=75.5%) reported sexual problems because of SCD. Orgasms were much less likely (χ(2)=13.1, P=0.006) to be normal in males (n=5, 5%) compared with females (n=11, 22%). Males had significantly worse (χ(2)=26.0, P=0.001) psychogenic genital functioning (normal n=9, 9%) than females (normal n=13, 26%) and worse (χ(2)=10.8, P=0.013) reflex genital functioning. Normal ejaculation was reported in only three (3%) men. Most (n=26, 52%) women reported reduced or absent menstruation pattern since SCD. The SR-iSCI-sexual function provides a useful tool for researchers and clinicians to collect information regarding patient-reported sexual functioning after SCD and to facilitate comparative studies.

    Most studies on parent-adolescent sexual health communication come from developed countries and are based on either parents' or children's reports. In developing countries, there is little evidence about the agreement among reports of all parties involved in parent-adolescent sexual health communication. The objective of this study is to explore the congruence (agreement) between adolescents and their parents about how frequently they discuss on selected sexual health topics. A total of 1606 parent-adolescent dyads of adolescents attending the first year in public high schools and their parents, in Morelos, Mexico were sampled in this study. The participants completed a self-administered questionnaire that included the frequency of parent-adolescent communication about eight sexual health topics. An ordinal logistic threshold model was used to estimate intra-class correlation coefficients within parent-adolescent dyads (as a measure of congruence) and to test if thresholds were equal between parents and adolescents. Congruence in reported frequency of parent-adolescent sexual health communication ranged from 0.205 (menstruation) to 0.307 (condoms) for mother-adolescent dyads, and from 0.103 (ejaculation) to 0.380 (condoms) for father-adolescent dyads. The thresholds (i.e., the cutoff points that define the categories in the observed ordinal variable) differed between parents and adolescents for each of the sexual health topics explored (p<0.05 for father-adolescent dyads and p<0.001 for mother-adolescent dyads). Our findings suggest a low congruence between parents' and adolescents' reports on parent-adolescent sexual health communication. This might be due to interpretation of frequency and intensity of sexual health communication which differs between parents and adolescents.

    Full Text Available Abstract Background There is continuing concern about high pregnancy rates and increasing numbers of sexually transmitted infections being detected in Scottish adolescents. Consistent evidence about factors associated with risky sexual behaviours, including early first sexual intercourse, may help to identify adolescents at risk and help improve interventions. This study aimed to provide detailed analysis of the evidence of the associations between individual factors and early sexual intercourse using cross-sectional questionnaire data from 4,379 Scottish adolescents who participated in a sexual health intervention evaluation. Findings Multivariate secondary analysis showed that aspects of family and school life such as decreasing parental monitoring (OR 1.45, 95% CI 1.24–1.70 and decreasing enjoyment of school (OR 2.55, 95% CI 2.15–3.03 were associated with reporting previous sexual intercourse. Furthermore, females were more likely to report previous sexual intercourse than males (OR 1.48, 95% CI 1.14–1.91. Several factors commonly used to inform sexual health intervention design, such as socioeconomic status, self-esteem and religion, were not independently associated. Conclusion These results contribute to the evidence base for the association of several factors with early initiation of sexual activity. The findings suggest that interventions aiming to delay first intercourse may need to consider targeting aspects of individuals' connection to their school and family. Furthermore, the results do not support the need to consider socio-economic background, religion or self-esteem of the individuals in intervention design.

  10. On the Relationship Between Automatic Attitudes and Self-Reported Sexual Assault in Men

    2013-01-01

    Research and theory suggest rape supportive attitudes are important predictors of sexual assault; yet, to date, rape supportive attitudes have been assessed exclusively through self-report measures that are methodologically and theoretically limited. To address these limitations, the objectives of the current project were to: (1) develop a novel implicit rape attitude assessment that captures automatic attitudes about rape and does not rely on self-reports, and (2) examine the association between automatic rape attitudes and sexual assault perpetration. We predicted that automatic rape attitudes would be a significant unique predictor of sexual assault even when self-reported rape attitudes (i.e., rape myth acceptance and hostility toward women) were controlled. We tested the generalizability of this prediction in two independent samples: a sample of undergraduate college men (n = 75, M age = 19.3 years) and a sample of men from the community (n = 50, M age = 35.9 years). We found the novel implicit rape attitude assessment was significantly associated with the frequency of sexual assault perpetration in both samples and contributed unique variance in explaining sexual assault beyond rape myth acceptance and hostility toward women. We discuss the ways in which future research on automatic rape attitudes may significantly advance measurement and theory aimed at understanding and preventing sexual assault. PMID:22618119

    Sexual and reproductive health (SRH) is protected by the public authorities to ensure that people enjoy a free, satisfying, and safe sexual life. Despite the approval of the National Sexual and Reproductive Health Strategy in 2011, the progress achieved may be jeopardized by recent proposals for legislative changes affecting this area (abortion Law and 16/2012 Law) and by the impact of the current economic crisis. This article aims to describe the current situation of sexual and reproductive health in the Spanish population and to identify the potential impact of the economic crisis. To this end, we used the following information sources: the National Sexual Health Survey, the DAPHNE surveys, births and fetal deaths statistics from the Spanish National Institute of Statistics, the Registry of Voluntary Pregnancy Interruptions, reports from the National Epidemiology Center, and the National AIDS Registry. Sexual health and the availability of information are rated as good by the Spanish population. Among young people, schools and health services have become less important as information sources and the internet has become more important. Since the beginning of the crisis, contraceptive use and fertility have declined and maternity has been delayed. The economic crisis seems to have affected some indicators of sexual and reproductive health. However, the potential effects on other indicators should continue to be monitored because insufficient time may have passed for accurate determination of the full effect of the crisis.

    Childhood cancer survivors (CCS) are at an increased risk of developing metabolic syndrome (MetSyn), which may be reduced with lifestyle modifications. The purpose of this investigation was to characterize lifestyle habits and associations with MetSyn among CCS. CCS who were ≥ 10 years from diagnosis, aged > 18 years, and participating in the St. Jude Lifetime Cohort Study completed medical and laboratory tests and a food frequency questionnaire. The Third Report of the National Cholesterol Education Program Adult Treatment Panel criteria were used to classify participants with MetSyn. Anthropometric, food frequency questionnaire, and self-reported physical activity data were used to characterize lifestyle habits according to World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations. Those who met ≥ 4 of 7 recommendations were classified as having followed guidelines. Sex-stratified log-binomial regression models were used to evaluate associations between dietary/lifestyle habits and MetSyn, adjusted for age, age at cancer diagnosis, receipt of cranial radiotherapy, education, and household income. Among 1598 CCS (49.2% of whom were male, with a median age of 32.7 years [range, 18.9 years-60.0 years]), 31.8% met criteria for MetSyn and 27.0% followed WCRF/AICR guidelines. Females who did not follow WCRF/AICR guidelines were 2.4 times (95% confidence interval, 1.7-3.3) and males were 2.2 times (95% confidence interval, 1.6-3.0) more likely to have MetSyn than those who followed WCRF/AICR guidelines. Adherence to a heart-healthy lifestyle is associated with a lower risk of MetSyn among CCS. There is a need to determine whether lifestyle interventions prevent or remediate MetSyn in CCS. © 2014 American Cancer Society.

    Full Text Available Aim of the study. The present work aimed to assess the association between cognitive functions, the lifetime occurrence of psychotic symptoms, and reported adverse effects of antipsychotic treatments inpatients with bipolar disorders.Methods. In the present work, 44 bipolar disorder inpatients hospitalized in the Affective Disorders Unit of the Institute of Psychiatry and Neurology in Warsaw, were investigated. All of them met the criteria of remission and were prepared for release from the hospital unit. Twenty-two patients were hospitalized in the manic stage of the illness, and 22 were in the depressive stage of illness. Both groups were assessed using adequate psychiatric rating scales (HDRS or YMRS and CAMRS and neuropsychological tests (WCST, TMT, Stroop Test and Verbal Fluency Test.Results. Patients who had a prior history of psychotic symptoms had poorer verbal functioning in comparison to subjects without such a history. However, individuals hospitalized in the manic state of disease, and who reported more adverse events after antipsychotic medication during the whole course of illness, had worse results in some parameters of executive function measurements in the WCST test, namely occurring in a greater percentage of nonperseverative errors and a lower number of completed categories.Discussion. Generally the results confirm findings according to which, patients with the history of psychosis performe worse on neurocognitive tasks. However, the nature of dysfunctions found, generates questions about its relations with the experience of psychosis and antipsychotic treatment. Conclusion: Different aspects of cognitive dysfunctions may be related to the experience of psychosis and antipsychotic treatment in patients with bipolar disorders.

    The association between perceived workplace psychological stress, over the entire work career, and cancer among men has never been assessed. This was explored in the context of a population-based case-control study conducted in Montreal, Canada. 3103 incident cancer cases (11 types) diagnosed in 1979-1985 and 512 population controls were interviewed. Subjects described in detail each job held during their lifetime, including the occurrence of stress, and its reason. Logistic regression estimated odds ratios (OR) and 95% confidence intervals (CI) for the association between perceived workplace stress and its duration, and each cancer site, adjusting for lifestyle and occupational factors. Employment in at least one stressful job was associated with increased odds of cancers of the lung (OR=1.33, 95% CI: 1.01-1.75), colon (OR=1.51, 95% CI: 1.15-1.98), bladder (OR=1.37, 95% CI: 1.03-1.81), rectal (OR=1.52, 95% CI: 1.10-2.10), and stomach (OR=1.53, 95% CI: 1.08-2.15). A duration-response trend was found for cancers of the lung, colon, rectum, stomach, and for NHL. Subjects reported changes in stress level over their career. Perceived stress was ascribed to several sources, including high demand and time pressure, financial issues, job insecurity, and hazardous conditions. Prolonged exposure to perceived stress at work was associated with greater odds of cancer at 5 out of 11 sites. While over reporting of stress by cases cannot be fully ruled out, these associations, if substantiated, would bear important public health significance. Prospective studies building on detailed stress assessment protocols considering all sources and changes over the career are necessary. Copyright © 2016 Elsevier Inc. All rights reserved.

    Sexually transmitted diseases are still highly prevalent worldwide and represent an important public health problem. Psychiatric patients are at increased risk of sexually transmitted diseases but there are scarce published studies with representative data of this population. We sought to estimate the prevalence and correlates of self-reported sexually transmitted diseases among patients with mental illnesses under care in a national representative sample in Brazil (n=2145). More than one quarter of the sample (25.8%) reported a lifetime history of sexually transmitted disease. Multivariate analyses showed that patients with a lifetime sexually transmitted disease history were older, had history of homelessness, used more alcohol and illicit drugs, suffered violence, perceived themselves to be at greater risk for HIV and had high risk sexual behavioral: practised unprotected sex, started sexual life earlier, had more than ten sexual partners, exchanged money and/or drugs for sex and had a partner that refused to use condom. Our findings indicate a high prevalence of self-reported sexually transmitted diseases among psychiatric patients in Brazil, and emphasize the need for implementing sexually transmitted diseases prevention programs in psychiatric settings, including screening, treatment, and behavioral modification interventions.

    Background Lesbian, gay, bisexual, and transgender individuals are at higher risk for substance use and substance use disorders than heterosexual individuals and are more likely to seek substance use treatment, yet sexual orientation and gender identity are frequently not reported in the research literature. The purpose of this study was to identify if sexual orientation and gender identity are being reported in the recent substance use literature, and if this has changed over time. Method The PsycINFO and PubMed databases were searched for articles released in 2007 and 2012 using the term “substance abuse” and 200 articles were randomly selected from each time period and database. Articles were coded for the presence or absence of sexual orientation and gender identity information. Results Participants’ sexual orientation was reported in 3.0% and 4.9% of the 2007 and 2.3% and 6.5% of the 2012 sample, in PsycINFO and PubMed sample articles, respectively, while non-binary gender identity was reported in 0% and 1.0% of the 2007 sample and 2.3% and 1.9% of the 2012 PsycINFO and PubMed sample articles. There were no differences in rates of reporting over time. Conclusions Sexual orientation and gender identity are rarely reported in the substance abuse literature, and there has not been a change in reporting practices between 2007 and 2012. Recommendations for future investigators in reporting sexual orientation and gender identity are included. PMID:25496705

    2015-03-01

    Differences in sexual functioning of adolescents with and without autism spectrum disorder (ASD) are understudied. In the current study, self-reported sexual behaviours, interests and attitudes of 50 adolescent boys, aged 15-18, with at least average intelligence and diagnosed with ASD, were compared with a matched general population control group of 90 boys. Results demonstrated substantial similarity between the groups in terms of sexual behaviours. The only significant difference was that boys with ASD reacted more tolerant towards homosexuality compared to the control group. Results reveal that sexuality is a normative part of adolescent development in high-functioning boys with ASD. Hence, attention should be given to this topic in education and mental health care.

    Traditional factors that once explained men’s sexual difficulties appear insufficient to account for the sharp rise in erectile dysfunction, delayed ejaculation, decreased sexual satisfaction, and diminished libido during partnered sex in men under 40. This review (1) considers data from multiple domains, e.g., clinical, biological (addiction/urology), psychological (sexual conditioning), sociological; and (2) presents a series of clinical reports, all with the aim of proposing a possible direction for future research of this phenomenon. Alterations to the brain's motivational system are explored as a possible etiology underlying pornography-related sexual dysfunctions. This review also considers evidence that Internet pornography’s unique properties (limitless novelty, potential for easy escalation to more extreme material, video format, etc.) may be potent enough to condition sexual arousal to aspects of Internet pornography use that do not readily transition to real-life partners, such that sex with desired partners may not register as meeting expectations and arousal declines. Clinical reports suggest that terminating Internet pornography use is sometimes sufficient to reverse negative effects, underscoring the need for extensive investigation using methodologies that have subjects remove the variable of Internet pornography use. In the interim, a simple diagnostic protocol for assessing patients with porn-induced sexual dysfunction is put forth. PMID:27527226

    Accurate data on young people's sexual behaviour and sexual health practice is essential to inform effective interventions and policy. However, little empirical evidence exists to support methodological design decisions in projects assessing young people's sexual health, especially in African contexts. This short report uses original empirical data collected in Ghana in 2012 to assess the effects of data collection mode and interviewer gender on young people's reporting of sexual health and access to supportive sexual health resources. The findings indicate that the effect of data collection mode may vary by gender, and there is no indication of an interviewer gender effect for males in this study. Preliminary results suggest that building strong rapport with research participants in this context may lead to reduced sexual health data quality. These findings merit further investigation and have direct implications for the design of projects measuring sexual health and related variables in Ghana.

    2015-01-01

    Teachers in many countries are mandated by law, professional codes, or education authorities to report child abuse and neglect, including child sexual abuse. However, teachers may not receive adequate preparation for such sensitive interventions, as preservice teacher education degrees provide very few or no compulsory courses on child protection and crucially related, lifelong health and well-being issues. So, where do preservice teachers source their information regarding the mandatory reporting of such abuse? This research examines preservice teachers' professional university education for their sources of information about mandatory reporting and child sexual abuse. A sample cohort of 56 final 4th-year university bachelor of education (primary school) student teachers in Australia identified the sources they used regarding 10 important aspects of child protection. The results suggest that most did not learn about mandatory reporting or child sexual abuse, and others cited sparse and sporadic public media as their primary information source. These findings, building on previous evidence about inadequate or nonexistent preservice mandatory intervention courses in primary teacher education, may guide the design of appropriate training responses enhancing educational professionals' knowledge, competencies, skills, and efficacies as mandatory reporters of child sexual abuse.

    Women represent almost half of the people living with HIV worldwide. Although social discrimination has been recognized as a major obstacle to HIV prevention, few empirical studies have examined the effects of sexism on women's HIV sexual risk behaviors. We analyzed data collected from an ethnically diverse sample of 754 women attending family planning clinics in the San Francisco Bay Area. A majority of respondents reported lifetime experiences of sexism (e.g., 94% reported sexual harassment). Structural equation modeling results demonstrated that experiences of sexism and reports of recent unprotected sex with a primary or a secondary sexual partner were linked through psychological distress and difficult sexual situations. Our results suggest the need to develop HIV prevention strategies for women that address two mechanisms-psychological distress and difficult sexual situations-that link social discrimination to women's sexual risk for HIV.

  7. Child sexual abuse and mandatory reporting intervention preservice content preferred by student teachers.

    Goldman, Juliette D G; Grimbeek, Peter

    2014-01-01

    The importance of preservice university teacher training about child sexual abuse and its mandatory reporting intervention is addressed in educational literature, although very little is known about student teachers' learning interests and preferences in this area. In this article, student teachers refer to students in university who are training to become teachers whose training includes teaching experiences in schools. This study examines the content about child sexual abuse and its intervention that student teachers believe they should learn. Results based on quantitative analyses show the relative importance of gender in determining responses to questions about university training and, to a lesser extent, the importance of a previous acquaintance with victims of sexual abuse, previous employment, and the length of the university course. Results based on qualitative data show that content knowledge preferred by elementary/primary and secondary school student teachers includes the teacher's role in mandatory reporting of child sexual abuse and signs, experiences, and responses to student disclosure. Student teachers prefer content examples of school professionals' responses and procedures after disclosure and prefer direct learning content from intervening school professionals. These outcomes could usefully guide teachers and educators who design intervention curricula on child sexual abuse for preservice teachers.

    Sexual minority (lesbian, gay, bisexual) populations have a higher prevalence of mental health and substance use disorders compared to their heterosexual counterparts. Such disparities have been attributed, in part, to minority stressors, including distal stressors such as discrimination. However, few studies have examined associations between discrimination, mental health, and substance use disorders by gender among sexual minority populations. We analyzed data from 577 adult men and women who self-identified as lesbian, gay, or bisexual and participated in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Six questions assessed discrimination due to sexual orientation. Weighted multivariable logistic regression examined associations between experiences of sexual orientation discrimination and both mental health and substance use disorders. Analyses were conducted separately for sexual minority men and women, adjusting for sociodemographic covariates. Sexual minority men who ever experienced discrimination (57.4%) reported higher odds of any lifetime drug use disorder and cannabis use disorder compared to sexual minority men who never experienced discrimination. Sexual minority women who ever experienced discrimination (42.9%) reported higher odds of any lifetime mood disorder and any lifetime anxiety disorder compared to sexual minority women who never experienced discrimination. The findings suggest that discrimination is differentially associated with internalizing (mental health) and externalizing (substance use) disorders for sexual minority men and women. These findings indicate a need to consider how homophobia and heteronormative discrimination may contribute to distinct health outcomes for lesbian and bisexual women compared with gay and bisexual men.

    In this study, we used data from Add Health Waves II and III to compare men who had been incarcerated to those who had not, and examined whether incarceration was associated with increased numbers of sexual partners and increased odds of concurrent partnerships. We used multivariate regression and propensity-score matching to compare sexual behavior of Wave III male respondents who had been incarcerated with those who had not, and compared sexual behavior at Wave II to identify differences in sexual behavior prior to incarceration. Incarceration was associated with an increased rate of lifetime sexual partnership, but this was attenuated by substance use. Criminal justice involvement was associated with increased odds of having partners who report concurrent partnerships, but no further increase was seen with incarceration. There were no significant sexual behavior differences prior to incarceration. These results suggest that the criminal justice system and substance use may interact to shape sexual behavior.

    China has a large migrant population, including many young unmarried women. Little is known about their sexual behavior, contraceptive use, and risk of unintended pregnancy. 475 unmarried female migrants aged 15-24, working in 1 of 6 factories in 2 districts of Changzhou city, completed an anonymous self-administered questionnaire in May 2012 on demographic characteristics, work and living situation, and health. We examined demographic and migration experience predictors of sexual and contraceptive behavior using bivariate and multivariate regressions. 30.1% of the respondents were sexually experienced, with the average age at first sex of 19 years (standard deviation=3). 37.8% reported using contraception at first sex, 58.0% reported using consistent contraception during the past year, and 28.0% reported having at least 1 unintended pregnancy with all unintended pregnancies resulting in abortion. Those who had had at least 1 abortion reported having on average 1.6 abortions [SD=1] in total. Migrating with a boyfriend and changing jobs fewer times were associated with being sexually experienced. Younger age, less education, and changing jobs more times were associated with inconsistent contraceptive use. These findings demonstrate there is an unmet need for reproductive health education and services where these women work as well as in their hometown communities. This education must begin early to reach young women before they migrate. © Zong et al.

    Seven cases of sexual behavior during sleep (SBS) have been recently reported. The subjects had histories of behavioral parasomnias as well as positive family histories of parasomnia. A 27 year-old man with a history of sexual behavior during sleep was reported. His sleep history disclosed sleepwalking (SW) since 9 years of age. He also developed episodes of highly disruptive and violent nocturnal behavior with dream enactment at age 20 years, which often resulted in physical injuries either to himself or his wife and infant. His wife also reported episodes of amnestic sexual behavior that began 4 years before referral. During the episodes, the patient typically procured his wife, achieving complete sexual intercourse with total amnesia. Physical and neurological diagnostic workups were unremarkable. Family history disclosed sleepwalking in his brother. He was put on 2mg/day of bedtime clonazepam with a remarkable clinical improvement. This case involves either the combination of violent and non-violent sleepwalking with SBS, or the superimposition of presumed REM sleep behavior disorder (RBD) on top of preexisting SW in a man who also developed SBS in adulthood. Thus, this is a case report of probable parasomnia overlap syndrome.

    The study had two aims: (1) To investigate whether mothers with a history of contact child sexual abuse were anxious about the intimate aspects of parenting compared with a clinical comparison group. (2) To determine if there was any relationship between the mother's anxieties and the kind of parenting they recalled receiving themselves. Two groups of mothers in mental health out-patient care were interviewed; 34 women with a history of contact child sexual abuse and 29 women with no history of sexual abuse. They completed the Intimate Aspects of Parenting Questionnaire, The Parenting Stress Index (Short form) The Parental Bonding Instrument and The General Health Questionnaire-28. The index group also completed a sexual abuse history questionnaire. Mothers with a history of child sexual abuse were significantly more anxious about intimate aspects of parenting than the comparison group. They also reported significantly more overall stress as parents. The index group recalled that their own parents were significantly less caring and that their fathers more controlling than the comparison group. A low score on Father Care was significantly associated with concerns about intimate parenting, but not with total parenting stress. By contrast, a low score on Mother Care was significantly associated with higher stress experienced as a parent, but not as strongly with anxieties about intimate parenting. Mothers with a history of contact child sexual abuse who attend mental health services are often worried that their normal parenting behaviors may be inappropriate or seen as such by other people. These anxieties seem associated with their history of childhood sexual abuse.

    Gay and bisexual men (GBM) continue to have a disproportionately higher HIV incidence than any other group in Canada and the United States. This study examined how multiple co-occurring psychosocial problems, also known as a syndemic, contribute to high-risk sexual behavior among GBM. It also examined the impact of early life adversity on high-risk sexual behavior as mediated by syndemic severity. A sample of 239 GBM completed self-report questionnaires at baseline and 6-month follow-up. Syndemic variables included depression, polysubstance use, and intimate partner violence. Early life adversity variables measured retrospectively included physical and verbal bullying by peers and physical and sexual abuse by adults. A Cochran-Armitage trend test revealed a proportionate increase between number of syndemic problems and engagement in high-risk sex (p indirect effects of two types of early life adversity on high-risk sex via syndemic severity: verbal bullying by peers and physical abuse by adults. There was also an overall effect of physical bullying by peers on high-risk sexual behavior, but no specific direct or indirect effects were observed. Consistent with syndemic theory, results provide evidence that certain types of early life adversity impact high-risk sex later in life via syndemic problems. Behavioral interventions to reduce sexual risk among GBM should address anti-gay discrimination experienced before adulthood as well as adult psychological problems.

    To identify correlates of risky sexual behavior among adolescents surviving childhood cancer. The Child Health and Illness Profile-Adolescent Edition (CHIP-AE) was completed by 307 survivors of childhood cancer aged 15-20 years (M age at diagnosis 1.53 years; range 0-3.76). Univariate analyses were performed using χ² and Fisher's Exact tests, and multivariable logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for risky sexual behaviors. Diagnosis of central nervous system cancer (OR = .13, 95% CI: .02-.96, p sexual intercourse. Good psychological health (scores ≥-1.5 SD on the CHIP-AE Emotional Discomfort scale) associated with decreased risk of early intercourse (OR = .19, CI: .05-.77, p = .02), whereas high parental education (≥ college degree) associated with decreased risk of multiple lifetime sexual partners (OR = .25, CI: .09-.72, p = .01). Increased time from diagnosis (OR = .27, CI: .10-.78, p = .02) and psychological health (OR = .09, CI: .02-.36, p sexual behavior in adolescents surviving childhood cancer is associated with cancer type, time since diagnosis, psychological health, alcohol use, and peer influences. Consideration of these factors may provide direction for future interventions designed to reduce adolescent sexual risk-taking.

    Both emotions and cognitions seem to play a role in determining sexual arousal. However, no studies to date have tested the effects of self-reported thoughts on subjective sexual arousal and genital response using psychophysiological methods. The aim of the present study was to evaluate the role of self-reported thoughts and affect during exposure to erotic material in predicting subjective and genital responses in sexually healthy men. Twenty-seven men were presented with two explicit films, and genital responses, subjective sexual arousal, self-reported thoughts, and positive and negative affect were assessed. Men's genital responses, subjective sexual arousal, affective responses, and self-reported thoughts during exposure to sexual stimulus were measured. Regression analyses revealed that genital responses were predicted by self-reported thoughts (explaining 20% of the variance) but not by affect during exposure to erotic films. On the other hand, subjective sexual arousal was significantly predicted by both positive and negative affect (explaining 18% of the variance) and self-reported thoughts (explaining 37% of the variance). Follow-up analyses using the single predictors showed that "sexual arousal thoughts" were the only significant predictor of subjective response (β = 0.64; P < 0.01) and that "distracting/disengaging thoughts" were the best predictor of genital response (β = -0.51; P < 0.05). The findings of this study suggest that both affect and sexual arousal thoughts play an important role in men's subjective sexual response, whereas genital response seems to be better predicted by distracting thoughts. © 2014 International Society for Sexual Medicine.

    In forensic research, there is a controversial discussion concerning the changeability or stability of pedophilia. Seto (2012) conceptualized pedophilia as a sexual age orientation characterized by an early onset, correlations with sexual and romantic behavior, and stability over time. However, empirical data are sparse and are mostly based on samples of detected offenders. The present study examined self-reported arousal to sexual fantasies involving children in a clinical sample of pedo-/hebephiles. In Study 1, retrospective self-reports on the age of onset and duration of sexual interest in minors were examined. In Study 2, the stability and variability of self-reported arousal to sexual fantasies involving children were evaluated prospectively. Non-prosecuted self-identifying pedo-/hebephilic men seeking professional help were recruited within the Berlin Prevention Project Dunkelfeld. Between 2005 and 2013, 494 participants completed the intake assessment. Self-reported data were collected via questionnaire focusing on sexual arousal to fantasies during masturbation involving prepubescent and/or early pubescent minors. Subsequent assessments of sexual arousal were obtained for 121 of the participants. The average time between the first and last assessment was approximately 29 months. Spearman's correlation coefficients examined the between-group rank-order and Wilcoxon signed-rank tests examined the within-individual mean-level stability. The majority of subjects reported an early onset of their pedo-/hebephilic sexual arousal. The rank-order stability was medium to high. Over the investigated period, the majority of subjects showed no or only minimal decrease or increase of self-reported sexual arousal. These results suggested that sexual arousal to fantasies involving prepubescent and/or early pubescent children is stable. Furthermore, the results support the conceptualization of pedo-/hebephilia as a sexual age orientation in men.

    Described case report speaks in favour of the relation between childhood sexual abuse with the development of conversion disorder. Following Salmonella poisoning, adolescent, at the age of 16, develops series of severe somatic symptoms. Results of diagnostic procedures excluded organic foundation of the symptoms; diagnosis of conversion disorder is established. Soon, patient's problems stop abruptly and spontaneously, and the aetiology of the mental disorder remains unexplained. Six years later, adolescent reveals for the first time data about the childhood sexual abuse during the forensic evaluation (within the court process related to the request for compensation for the complications which occurred following the Salmonella infection). During the forensic evaluation, we had insight into the previous medical history, while an interview, psychological and psychiatric exploration was conducted with the examinee. Data about the sexual abuse retrospectively explain the dynamics of the development of conversion disorder. The described case indicates that sexual abuse of children and adolescents frequently remains unrecognized, which has sequels for treatment and prevention of subsequent consequences for mental health. It is important to emphasize the significance of examining history of abuse during the diagnostic of certain mental disorders. Forensic implications of the case have not been discussed in details for the needs of this report.

    The present study aims at describing the psychological complaints reported, as a part of the criminal investigation process, by the victims of sexual abuse as a part of the criminal investigation process, without attempting at reaching a medical diagnosis; and it discusses the relation of these reports with variables such as victim's gender, age and relation to the offender, type and duration of abuse, and parental marital status of the victim. Data is obtained from the statements of childhood sexual abuse (CSA) victims under the age of 15, as taken by Istanbul Juvenile Justice Department between the years 2009 and 2012. The sample consists of 175 cases with a total of 202 victim statements. Through the use of content analysis, the main and sub-categories of themes of the statements were determined. By means of the evaluation of the psychological condition of victims, we evaluated them in two categories: psychological complaints including self-harm and risk taking behaviors and psychological complaints with no self-harm and risk taking behaviors. The statistical analyses yield significant relations between the psychological complaints and children's parental marital status. Analysis of initial statements of sexual abuse victims is important as it may greatly contribute to professionals diagnosing and treating psychological complaints of these victims. It is essential that victims of sexual abuse should receive immediate psychological support starting with the criminal investigation process.

    Objective To examine dating violence perpetration and victimization (physical, psychological, and sexual) and lifetime substance use (alcohol, marijuana, and hard drugs) as longitudinal predictors of adolescents’ risky sexual behavior across one year, and to determine whether predictors varied across adolescents’ gender and ethnicity. Methods A sample of Caucasian, African American, and Hispanic male and female adolescents from 7 public high schools in Texas (N = 882) participated. Adolescents completed self-report measures of dating violence, lifetime substance use, and risky sexual behavior at baseline and, 1-year later, completed a second assessment of their risky sexual behavior. Results Path analysis demonstrated that greater physical dating violence victimization, lifetime alcohol use, lifetime marijuana use, and age (being older) were all significant predictors of risky sexual behavior at the 1-year follow-up. These results did not vary across gender or the three ethnic groups (Caucasian, African American, and Hispanic). Conclusions Overall, substance use was a longitudinal predictor of risky sexual behavior across the three ethnic groups, with physical dating violence victimization being the only type of dating violence longitudinally predicting risky sexual behavior. Prevention efforts should consider the roles of physical dating violence and substance use in preventing risky sexual behavior. PMID:25797949

    Motivations for and against sex are salient predictors of engaging in or abstaining from sex in cross-sectional studies. Participants (N = 637, 41.4% male) provided data on their motivations for and against sex and lifetime sexual behavior prior to entering college and six months into the first year in college. Longitudinal data were used to examine differences on motivations for and against sex reported the summer before college entrance for students who continued to abstain (Nevers, 44.7%), transitioned to sexual behavior in the following months (Transitioners, 11.0%), and who were previously sexually active (Actives, 44.3%). Multivariate analysis of variance analyses indicated that Transitioners evidenced mean-level differences in motivations surrounding sex (greater intimacy and enhancement motives for sex, lower values motives against sex) prior to their behavioral initiation compared to Nevers. In addition, Transitioners reported greater changes in motivations from pre-college to the six-month follow-up, including increased enhancement motivations for sex and decreased values and not ready motivations against sex. Men reported more important motivations for sex and less important motivations against sex than women, with an interaction showing that sexually experienced women reported more important intimacy motivations and sexually inexperienced men reported more important coping motivations for sex. Identifying salient motivations associated with imminent changes in sexual behavior may support the development of sexual health promotion programs that seek to reach sexually inexperienced individuals at important times of transition.

    Full Text Available Background: In patients with co-morbid obsessive–compulsive disorder (OCD and posttraumatic stress disorder (PTSD, repetitive behavior patterns, rituals, and compulsions may ward off anxiety and often function as a coping strategy to control reminders of traumatic events. Therefore, addressing the traumatic event may be crucial for successful treatment of these symptoms. Objective: In this case report, we describe a patient with comorbid OCD and PTSD who underwent pharmacotherapy and psychotherapy. Methods: Case Report. A 49-year-old Dutch man was treated for severe PTSD and moderately severe OCD resulting from anal rape in his youth by an unknown adult man. Results: The patient was treated with paroxetine (60 mg, followed by nine psychotherapy sessions in which eye movement desensitization and reprocessing (EMDR and exposure and response prevention (ERP techniques were applied. During psychotherapy, remission of the PTSD symptoms preceded remission of the OCD symptoms. Conclusions: This study supports the idea of a functional connection between PTSD and OCD. Successfully processing the trauma results in diminished anxiety associated with trauma reminders and subsequently decreases the need for obsessive–compulsive symptoms.

    Although "friends with benefits" relationships (FWBRs) are common and have been the subject of significant media and research attention, relatively little is known about them, especially in terms of how they differ from other types of relationships. The present research sought to compare the sexual outcomes of FWBRs to those of traditional romantic relationships via an online survey. Results revealed that FWBR partners were less likely to be sexually exclusive, had a lower frequency of sexual interaction, were less sexually satisfied, and generally communicated less about sex than romantic partners did. However, compared to romantic partners, FWBR partners devoted relatively more of the time spent together to sexual activity, practiced safe sex more frequently, communicated more often about extradyadic sexual experiences, and reported a greater number of lifetime casual sex partners. These findings indicate that the sexual outcomes of FWBRs and romantic relationships are quite distinct and provide evidence of the potential public health implications associated with both casual and committed sexual relationships.

    This study investigated stability and change in self-reported sexual orientation identity over time in youth. We describe gender- and age-related changes in sexual orientation identity from early adolescence through emerging adulthood in 13,840 youth ages 12-25 employing mobility measure M, a measure we modified from its original application for econometrics. Using prospective data from a large, ongoing cohort of U.S. adolescents, we examined mobility in sexual orientation identity in youth with up to four waves of data. Ten percent of males and 20% of females at some point described themselves as a sexual minority, while 2% of both males and females reported ever being "unsure" of their orientation. Two novel findings emerged regarding gender and mobility: (1) Although mobility scores were quite low for the full cohort, females reported significantly higher mobility than did males. (2) As expected, for sexual minorities, mobility scores were appreciably higher than for the full cohort; however, the gender difference appeared to be eliminated, indicating that changing reported sexual orientation identity throughout adolescence occurred at a similar rate in female and male sexual minorities. In addition, we found that, of those who described themselves as "unsure" of their orientation identity at any point, 66% identified as completely heterosexual at other reports and never went on to describe themselves as a sexual minority. Age was positively associated with endorsing a sexual-minority orientation identity. We discuss substantive and methodological implications of our findings for understanding development of sexual orientation identity in young people.

    INTRODUCTION: From the clinical forensic examination reports made at the Department of Forensic Medicine, the University of Copenhagen, in 2007 concerning rape, attempted rape and sexual assault (RAS), information about the assault, including both violence and the perpetrator's line of sexual...... action was extracted, analysed and compared to the observed lesions (LE). MATERIAL AND METHODS: A total of 184 girls and women were included in this retrospective study. RESULTS: 75.5% of the victims were under 30 years of age. Observed LE: 79% had observed LE. 41% had body LE only, 19% genito-anal LE...... only, and 40% had both body and genito-anal LE. Half of the victims, who reported no exposure to violence, had body LE. Five victims also had LE of a self-inflicted character. Genito-anal LE: 47% had genito-anal LE, 64% of whom had one or two, commonest a tear. Body LE: 64% had body LE. 57% was caused...

    The following is a population-based survey of the Central African Republic (CAR) female refugee population displaced to rural Djohong District of Eastern Cameroon and associated female Cameroonian host population to characterise the prevalence and circumstances of sexual violence. A population-based, multistage, random cluster survey of 600 female heads of household was conducted during March 2010. Women heads of household were asked about demographics, household economy and assets, level of education and sexual violence experienced by the respondent only. The respondents were asked to describe the circumstances of their recent assault. The lifetime prevalence of sexual violence among Djohong district female heads of household is 35.2% (95% CI 28.7-42.2). Among heads of household who reported a lifetime incident of sexual violence, 64.0% (95% CI 54.3-72.5) suffered sexual violence perpetrated by their husband or partner. Among the host population, 3.9% (95% CI 1.4-10.5) reported sexual violence by armed groups compared to 39.0% (95% CI 25.6-54.2) of female refugee heads of household. Women who knew how to add and subtract were less likely to report sexual violence during their lifetime (OR 0.16, 95% CI 0.08-0.34). Sexual violence is common among refugees and host population in Eastern Cameroon. Most often, perpetrators are partners/husbands or armed groups.

    An unrestricted sociosexual orientation (the endorsement of casual sex) has been found to correlate with undesirable behaviors and personality characteristics more so in men than in women. Using a community sample of men and women, we investigated the correlations between sociosexuality and behaviors, motives, attitudes, and fantasies related to sexual aggression. Participants (n = 168; ages 21-45) completed self-report measures of sociosexual orientation, sexual conservatism, rape myth acceptance, adversarial sexual beliefs, attitudes toward women, sexual behaviors, and perpetration of sexual aggression. Participants also wrote five brief stories that were scored for power and affiliation-intimacy motives and two sexual fantasies that were coded for the theme of dominance. For both men and women, an unrestricted sociosexual orientation was correlated with behavioral items indicating earlier life experiences with sex, a greater number of lifetime sex partners, and more frequent sexual activity. For men, an unrestricted sociosexual orientation was linked with higher levels of rape myth acceptance and adversarial sexual beliefs; more conservative attitudes toward women; higher levels of power motivation and lower levels of affiliation-intimacy motivation; and past use of sexual aggression. For women, an unrestricted sociosexual orientation was associated with sexual fantasies of dominance and lower levels of sexual conservatism.

    According to the World Health Organization, child abuse and neglect is "every kind of physical, sexual, emotional abuse, neglect or negligent treatment, commercial or other exploitation resulting in actual or potential harm to the child's health, survival, development or dignity in the context of a relationship of responsibility, trust or power". The aim of the present report is to inform about the most relevant aspects of child abuse and the characteristics of injuries to the head, neck, and orofacial regions, in addition to the suggested role of, and management by, the dentist for the evaluation of this condition, and also for reporting a case of a physically and sexually abused girl aged 5 years 8 months. Throughout the appointments, some type of abuse in this patient was suspected by the treating dentists at the clinic, mainly due to the initial behavior exhibited by the patient in the dental chair. Based on the clinical diagnostic an intensive preventive plan and restorative treatment was realized. The timely detection of the signs and symptoms of sexual abuse, often present in the orofacial region, place the pediatric dentist in a strategic situation, with the capacity to recognize, register, and later report those cases considered as suspect, including the dental treatment delivered and the intensive behavioral-psychological management, in order to achieve acceptation by the otherwise very anxious patient of the indicated restorative and preventive dental procedures. Key words:Child abuse, dentistry, behavior management.

    2016-10-03

    Online forms of sexual harassment and abuse as experienced by adults represent an emerging yet under-researched set of behaviors, such that very few studies have sought to estimate the extent of the problem. This article presents the results of an online survey of 2,956 Australian adult (aged 18 to 54 years) experiences of technology-facilitated sexual violence (TFSV) victimization. The prevalence of TFSV was analyzed in relation to a 21-item scale developed in accordance with prior conceptual research identifying multiple dimensions of TFSV including digital sexual harassment, image-based sexual abuse, sexual aggression and/or coercion, and, gender and/or sexuality-based harassment (including virtual sexual violence). Results revealed significant differences in lifetime TFSV victimization for younger (18-24) and non-heterosexual identifying adults. Lifetime TFSV victimization for men and women was not significantly different, though women were more likely to report sexual harassment victimization and men were more likely to report victimization through the distribution of non-consensual images, as well as gender and/or sexuality-based harassment. The authors conclude that although women and men report experiencing similar overall prevalence of TFSV victimization, the nature and impacts of those experiences differ in particular gendered ways that reflect broader patterns in both gender relations and "offline" sexual harassment.

  1. Making sense of children's sexual behavior in child care: An analysis of adult responses in special investigation reports.

    2014-10-01

    This paper investigates how adults respond to sexual behavior among children in child care. Culturally, childhood sexuality is variously understood as natural curiosity, a sign of sexual abuse, or a symptom of a sex-offender in the making. Given these competing cultural meanings, how are sexual-like behaviors by children managed by the adults who care for them? An analysis of qualitative data from Special Investigation Reports by childcare licensing consultants in the state of Michigan is used to examine how parents, child care providers, and child care licensing consultants manage and respond to sexual behavior between children in the context of child care. How sexual behavior is responded to depends primarily on who is doing the responding - parent, childcare provider, or state licensing consultant - rather than what type of behavior is being responded to. Parents respond to a wide range of behaviors between children as if they are incidents of sexual abuse. Childcare providers respond to many of those same incidents as misbehavior. Licensing consultants understand these incidents as violation of rules of supervision, but they were also the only group to ever ask if children's sexual behavior was potentially a sign of a child having been sexually abused in another setting. Providers and parents need more education about what kinds of sexual behavior to be concerned about and what kind to understand as common. More education that sexuality that is "rare" and persistent could be a sign of sexual abuse is needed by all parties. Copyright © 2014 Elsevier Ltd. All rights reserved.

  2. Overweight, obesity and female sexuality in perimenopause: a preliminary report

    Full Text Available Introduction: The research was conducted among patients of the Department of Perinatology and Gynaecology of the Poznań University of Medical Sciences. Its aim was to investigate the influence of overweight and obesity on female sexuality during the perimenopausal period. Preliminary results of the research are presented in the thesis, which was as a matter of fact intended as a preliminary report. The examination of sexual functions of the patients was performed with the use of the Female Sexual Function Index (FSFI form. Material and methods: Sixty-one women during the perimenopausal period filled out the survey, with the average age of these women being 51 years. Forty-two of the examined women had an appropriate body mass index (BMI, i.e. between 18.5 and 25, while for 19 of the women, the BMI was above normal. For statistical analysis and in order to assess the differences between the two above-mentioned groups of patients, the nonparametric Mann-Whitney test was applied. A statistically significant value was assumed at p < 0.05. The results of the conducted research indicated no such difference between the women with differing BMI for the specific domains of the FSFI test. Results: The results obtained show that research in the area needs to be continued. Conclusions: All the hitherto existing scientific studies also seem to indicate that the influence of overweight and obesity on female sexuality during the perimenopause has not yet been unambiguously proven. Beyond any doubt, however, sexual disorders appear in women at this time of life and the factors which determine them can vary greatly. Given the character of the situation, women ought to be supported both by a team of specialists representing different branches of medicine as well as by their relatives. The whole situation also calls for more research of the important subject matter.

  3. Sexual Regret

    Full Text Available The current study sought to answer three key questions about explaining the emotion of regret in the domain of casual sex: Are sex differences in sexual regret robust or attenuated in a highly egalitarian culture? What proximate psychological variables might explain sex differences in sexual regret? And what accounts for within-sex variation in experiences of sexual regret about casual sex. We conducted a study of 263 Norwegian students (ages 19–37 who reported how much they regretted having either engaged in, or passed up, their most recent casual sexual experience. Sex differences in sexual regret are not attenuated in this sexually egalitarian culture. The study revealed sex differences in worries about pregnancy, STIs, and reputation; however, these predictors did not succeed in accounting for the sex differences in regret engaging in casual sex. Sexual gratification and socio-sexual orientation both predicted the sex differences in casual sex regret. In contrast, only socio-sexual orientation attenuated the sex difference in regret passing up casual sex. Predictors of within-sex variation in casual sexual regret included worry about sexual reputation, experienced gratification during the encounter, and socio-sexual orientation. Discussion focuses on implications for the psychological design features of this relatively neglected emotion.

    Given the importance of reporting to sexual harassment prevention and intervention efforts, it is not surprising that an extensive scientific literature has developed on predictors of victims' decisions about making a formal report to authorities about their experiences. In contrast, little empirical work has focused on how reporting affects victims, particularly their psychosocial well-being. This study used a national sample of 1,562 former military Reservists who had experienced sexual harassment during their service to examine the relationship between reporting; experiences reporting; and psychosocial well-being, as indicated by post-harassment functioning, worst symptoms of posttraumatic stress disorder (PTSD) following the harassment, and current symptoms of depression. Making a formal report was not associated with well-being, but among those who did report, perceiving that the report had resulted in the harassment being addressed by authorities was associated with better post-harassment functioning and fewer symptoms of PTSD. Satisfaction with the reporting process showed the strongest association with well-being, demonstrating small but meaningful associations with depression and medium-to-large and medium associations with post-harassment functioning and PTSD, respectively. Although findings did not vary by gender, predictors accounted for more variance in well-being for men than women. In the whole sample, satisfaction with the reporting process mediated the relationship between victims' perceptions of system responsiveness to the report and post-harassment functioning and PTSD. Findings suggest that a victim's perceptions of and satisfaction with the reporting process may impact well-being more strongly than whether the victim made a report to authorities. Men may be even more strongly impacted by their experiences with the reporting process than women.

    The scope of this article is to outline the scenario of domestic, sexual and other forms of violence against children (0-9 years old) in Brazil for the year 2010. It is based on data from reports of domestic, sexual and other forms of violence registered with SINAN - Information System for Notifiable Diseases (Continuous VIVA). Absolute and relative numbers are presented, derived from reported violence, discriminating between children under 1 year of age and those between 1-9 years old, due to the specificities that exist in these age groups. Throughout the country, the number of reports among those under 10 years of age is low (17.1%). Differences were found for the distribution of reports in the different Brazilian States. Few municipalities and few services reported violence to SINAN-Net in 2010 in the country. Some differences were found between children under 1 year of age and those between 1 and 9 years of age, as for instance the relationship between the profile of the violence, the victim and the perpetrator, and the handling of the case. The quality of the reported information is discussed showing the high level of unreported data in some spaces of the reporting form. Lack of information may prejudice comprehension of the phenomenon, interfering with the planning, organization and operation actions of the health services in the country.

    This study aims to explore the association between early sex initiation and subsequent unsafe sexual behaviors and risks among Chinese female undergraduates. Of 4769 participants, 863 (18.1%) reported ever having sexual intercourse. The mean age of sexual debut was 19.3 (±1.7) years. Females initiating sex earlier were more likely to have first sex with men who were not their "boyfriends" and less likely to take contraception, to use a condom at first encounter, to use contraception consistently in past year, and/or to use condom consistently during the course of a sexual intercourse. They were more likely to have multiple lifetime and concurrent sexual partners, to report pregnancy, and be diagnosed with sexually transmitted diseases. Comprehensive early sex education should be advocated for young people, not only teaching knowledge of physical health but also providing practical skills training for making them consciously delay start of sexual activity or protecting themselves during sexual intercourse.

    Absorption is the origin of luminescence. But it must be noticed that the lifetime of luminescence might reversely influence the rate of absorption. In this paper, it is reported that the luminescence intensity of copper and manganese changes with the driving frequency at constant voltage. The variation of luminescent intensity depends only on the lifetime of luminescence but not on the type of quenching or other factors. Generally the rate of absorption is dominantly determined by the material property and the lifetime of luminescence centres, the absorption of shorter lifetime centre will be larger than that of the longer lifetime centre at the same excited condition.

    The authors present their 14-year experience about Information/education on sexually transmitted diseases/Aids and human sexuality. They describe the actions implemented, emphasizing the positive and negative points. Concerning the positive results they mention the divulgation of information about preventive measures against HIV infection/Aids, Sexually Transmitted Diseases and human sexuality to several people from scientific and non scientific community. Another positive point is the transmission of knowledge gotten in such experiences at undergraduation and graduation teaching, as well as the development of research. Concerning the negative aspects, the difficult to evaluate the information actions, specially lectures was perceived, mainly because it is a communication tool basically unilateral. The authors mention some facts that historically influenced the implementation of the official actions.

    Sexual problems are common during pregnancy, but the proportion of pregnant women who experience sexual distress is unknown. In non-pregnant samples, sexual distress is associated with lower sexual and relationship satisfaction. To identify the proportion of women experiencing sexual distress during pregnancy and to compare the sexual and relationship satisfaction of women who report sexual distress during pregnancy with that of women without distress. Two-hundred sixty-one pregnant women completed a cross-sectional online survey. Women completed validated measurements of sexual functioning (Female Sexual Function Index; score relationship satisfaction (Couples Satisfaction Index). Overall, 42% of women met the clinical cutoff for sexual distress. Of sexually active women (n = 230), 26% reported concurrent sexual problems and distress and 14% reported sexual distress in the absence of sexual problems. Sexual distress and/or problems in sexual functioning were linked to lower sexual and relationship satisfaction compared with pregnant women with lower sexual distress and fewer sexual problems. Sexual distress is common during pregnancy and associated with lower sexual and relationship satisfaction. Health care providers should ask pregnant women about feelings of sexual distress. Identifying pregnant women who experience sexual distress and referring them to appropriate resources could help minimize sexual and relationship problems during pregnancy. Vannier SA, Rosen NO.

    Sleep paralysis (SP) occurs when rapid eye movement (REM) activity and concomitant paralysis of the skeletal muscles persist as an individual awakens and becomes conscious of his/her surroundings. SP is often accompanied by frightening hallucinations that some researchers suggest may be confounded with memories of childhood sexual abuse (CSA; [McNally, R. J., & Clancy, S. A. (2005). Sleep paralysis in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse. Journal of Anxiety Disorders, 19, 595-602]). The purpose of this study was to evaluate relationships between CSA and SP. Based on self-report, participants (n=263) were categorized into three CSA groups: confirmed, unconfirmed, or no history of CSA. Relative to participants reporting no CSA history, those reporting CSA reported more frequent and more distressing episodes of SP. Post hoc analyses revealed that participants with clinically significant post-traumatic symptoms (irrespective of CSA history) also reported more frequent and more distressing episodes of SP. Significant correlations were found among SP indices and measures of post-traumatic symptoms, depression, dissociation, and absorption. Implications and future research directions are discussed.

    We examined change over time in the reported prevalence of men having sex with men and women having sex with women and acceptance of those behaviors in the nationally representative General Social Survey of U.S. adults (n's = 28,161-33,728, ages 18-96 years), 1972-2014. The number of U.S. adults who had at least one same-sex partner since age 18 doubled between the early 1990s and early 2010s (from 3.6 to 8.7 % for women and from 4.5 to 8.2 % for men). Bisexual behavior (having sex with both male and female partners) increased from 3.1 to 7.7 %, accounting for much of the rise, with little consistent change in those having sex exclusively with same-sex partners. The increase in same-sex partners was larger for women than for men, consistent with erotic plasticity theory. Attitudes toward same-sex sexual behavior also became substantially more accepting, d = .75, between the early 1970s and early 2010s. By 2014, 49 % of American adults believed that same-sex sexual activity was "not wrong at all," up from 11 % in 1973 and 13 % in 1990. Controlling for acceptance reduced, but did not eliminate, the increase in same-sex behavior over time. Mixed effects (hierarchical linear modeling) analyses separating age, time period, and cohort showed that the trends were primarily due to time period. Increases in same-sex sexual behavior were largest in the South and Midwest and among Whites, were mostly absent among Blacks, and were smaller among the religious. Overall, same-sex sexual behavior has become both more common (or at least more commonly reported) and more accepted.

    This paper reports on the first nationally representative study on the prevalence of emotional, physical, and sexual victimization of children by school staff in Israel. The study identifies groups of children that are at higher risk for such maltreatment. We examine the differences in staff-induced victimization by the children's gender, age group (junior high vs. high school), cultural groups (Jewish non-religious, Jewish-religious and Arab schools) and by socioeconomic status of the children's families. The study is based on a nationally representative sample of 10,410 Israeli students in Grades 7-11 in 161 schools across Israel. Students completed questionnaires during class. In addition, we obtained data on the socioeconomic status of the families of the students in each school. Overall, children reported high rates of victimization by staff members. Almost a quarter of all children participating in this study reported being emotionally maltreated by a staff member, almost a fifth (18.7%) reported being a victim of at least one type of physical forms of maltreatment, and 8.2% reported on at least one sexually inappropriate behavior by a staff member. The most vulnerable groups for all types of maltreatment were males, children in junior high schools, children in Arab schools, and children in schools with a high concentration of students coming from low-income and low-education families. The overall prevalence rates of staff maltreatment should be considered high and unacceptable. Although rates of physical and sexual maltreatment were lower than emotional maltreatment, they were still high and are worthy of greater attention. Both cultural beliefs and low family socioeconomic status increase vulnerability to staff maltreatment. We suggest conducting an educational campaign to reduce rates of staff maltreatment. We also recommend allocating more resources to support staff in low SES neighborhoods, to alleviate their stress and to provide them with the support

    Full Text Available Abstract Background Despite the signing of international peace agreements, a deadly war continues in the Democratic Republic of Congo (DRC and sexual violence is a prominent modus operandi of many military groups operating in the region. Methods Retrospective cohort study of women who presented to Panzi Hospital in 2006 requesting post-sexual violence care. Data was extracted and analyzed to describe the patterns of sexual violence. Results A total of 1,021 medical records were reviewed. A majority of attacks occurred in individual homes (56.5%, with the fields (18.4% and the forest (14.3% also being frequent locations of attack. In total, 58.9% of all attacks occurred at night. Of the four primary types of sexual violence, gang rape predominated (59.3% and rape Not Otherwise Specified (NOS was also common (21.5%. Sexual slavery was described by 4.9% of the survivors and a combination of gang rape and sexual slavery was described by 11.7%. The mean number of assailants per attack was 2.5 with a range of one to > 15. There were several demographic predictors for sexual slavery. Controlling for age, education level and occupation, a marital status of "single" increased the risk of sexual slavery (OR = 2.97, 95% CI = 1.12-7.85. Similarly, after controlling for other variables, age was a significant predictor of sexual slavery with older women being at a slightly reduced risk (OR = 0.96, 95% CI = 0.92-0.99. Women who experienced sexual slavery were 37 times more likely to have a resultant pregnancy in comparison to those who reported other types of sexual violence (OR = 37.50, 95% CI = 14.57-99.33. Conclusions Among sexual violence survivors presenting to Panzi Hospital in 2006, the majority of attacks occurred in women's own homes, often at night. This represents a pattern of violence that differs from other conflict settings and has important implications regarding protection strategies. Sexual violence in South Kivu was also marked with a

    To inform intervention approaches, the current study examined prevalence and comorbidity of recent use and history of abuse of alcohol, marijuana, and other illicit drugs as well as history of substance treatment among a sample of female victims of sexual assault seeking post-assault medical care. Demographic variables and prior history of assault were also examined to further identify factors relevant to treatment or prevention approaches. Participants were 255 women and adolescent girls seeking post sexual assault medical services who completed an initial follow-up assessment on average within 3 months post-assault. The majority (72.9%) reported recent substance use prior to assault, approximately 40% reported prior substance abuse history, and 12.2% reported prior substance treatment history. Prior history of assault was associated with recent drug use and history of drug abuse as well as substance treatment. Among those with prior histories of substance abuse and assault, assault preceded substance abuse onset in the majority of cases. Almost all those with prior treatment history reported recent drug or alcohol use. A portion of sexual assault survivors seen for acute medical services may benefit from facilitated referral for substance abuse treatment in addition to counseling at the time of screening. Assessment and intervention approaches should target alcohol, marijuana, and other illicit drug use and abuse. Substance use and associated impairment may serve as a rape tactic by perpetrators of assault. Substance use at the time of assault does not imply blame on the part of assault victims. Previous findings indicate that rape poses high risk of PTSD particularly among women with prior history of assault. Screening and intervention related to substance abuse should be done with recognition of the increased vulnerability it may pose with regard to assault and the high risk of PTSD within this population.

    2017-09-01

    We surveyed evaluators who conduct sexually violent predator evaluations ( N = 95) regarding the frequency with which they use the Psychopathy Checklist-Revised (PCL-R), their rationale for use, and scoring practices. Findings suggest that evaluators use the PCL-R in sexually violent predator cases because of its perceived versatility, providing information about both mental disorder and risk. Several findings suggested gaps between research and routine practice. For example, relatively few evaluators reported providing the factor and facet scores that may be the strongest predictors of future offending, and many assessed the combination of PCL-R scores and sexual deviance using deviance measures (e.g., paraphilia diagnoses) that have not been examined in available studies. There was evidence of adversarial allegiance in PCL-R score interpretation, as well as a "bias blind spot" in PCL-R and other risk measure (Static-99R) scoring; evaluators tended to acknowledge the possibility of bias in other evaluators but not in themselves. Findings suggest the need for evaluators to carefully consider the extent to which their practices are consistent with emerging research and to be attuned to the possibility that working in adversarial settings may influence their scoring and interpretation practices.

    Full Text Available In 2006 we conducted a cross-sectional study involving hospital clinical centres in five Italian cities to compare the sexual behaviour of HIV-positive MSM (men who have sex with men before and after the diagnosis of HIV infection. Each centre was asked to enrol 30 HIV-positive persons aged > 18 years. The questionnaire was administered to 143 MSM on average 9 years after HIV diagnosis. After diagnosis there was a decrease in the number of sexual partners: the percentage of persons who reported having had more than 2 partners decreased from 95.8% before diagnosis to 76.2% after diagnosis. After diagnosis, there was a significant decrease in the percentage of persons who had never (or not always used a condom with their stable partner for anal sex from 69.2% before diagnosis to 26.6% after diagnosis and for oral-genital sex from 74.8% before diagnosis to 51.7% after diagnosis. Though at-risk behaviour seems to decrease after diagnosis, seropositive MSM continue to engage in at-risk practices: one fourth of them did not use a condom during sexually transmitted infections (STI episodes, 12.5% of the participants had had sex for money, and 8.4% had paid for sex. The study shows that our sample of Italian HIV-positive MSM, though aware of being infected, engage in sexual behaviours that could sustain transmission of HIV and other STIs. The results could constitute the first step in implementing national prevention programs for persons living with HIV.

  19. Sleep paralysis in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse.

    2005-01-01

    Sleep paralysis typically occurs as individuals awaken from rapid eye movement sleep before motor paralysis wanes. Many episodes are accompanied by tactile and visual hallucinations, often of threatening intruders in the bedroom. Pendergrast [Victims of Memory: Incest Accusations and Shattered Lives, HarperCollins, London, 1996] proposed that individuals who report repressed or recovered memories of childhood sexual abuse (CSA) may misinterpret episodes of sleep paralysis as reemerging fragments of dissociated ("repressed") memories of CSA. To investigate this issue, we administered a sleep paralysis questionnaire to people reporting either repressed (n = 18), recovered (n = 14), or continuous (n = 36) memories of CSA, or to a control group reporting no history of CSA (n = 16). The prevalence of sleep paralysis was: repressed memory group (44%), recovered memory group (43%), continuous memory group (47%), and control group (13%). Among the six individuals in the recovered memory group who had experienced sleep paralysis, one interpreted it as related to sexual abuse (i.e., a rate of 17%). All other participants who had reported sleep paralysis embraced other interpretations (e.g., saw a ghost). Dissociation and depressive symptoms were more common among those who had experienced sleep paralysis than among those who denied having experienced it.

    Lesbian, gay, and bisexual youth (LGBY) report higher rates of mental health concerns compared to heterosexual youth due to minority stressors. This study examined the interpersonal and intrapersonal variables that predict psychological distress and self-reported suicide attempts in a sample of 61 LGBY in the Mid-South, which is a highly overlooked regional area for LGBY research. Youth who lost friends when coming out were 29 times more likely to report suicide attempts, and those who experienced psychological maltreatment from caregivers were 9.5 times more likely to report a suicide attempt. Internalized heterosexism, feelings of guilt or shame, and psychological maltreatment from caregivers were significant predictors of depression and anxiety symptoms. This study highlights the importance of creating affirming spaces for LGBY, particularly in areas of the country that experience greater political oppression of sexual minorities, such as the Mid-South.

    2005-02-01

    People who report either repressed or recovered memories of childhood sexual abuse (CSA) may have deficits in reality monitoring--the process whereby one discriminates memories of percepts from memories of images. Using signal detection methods, the authors found that adults reporting either repressed or recovered memories of CSA were less able to discriminate between words they had seen from words they had imagined seeing than were adults reporting either never having forgotten their CSA or adults reporting no history of CSA. Relative deficits in the ability to discriminate percepts from images (i.e., low d') were apparent on only some tests. The groups did not differ in their criterion--response bias--for affirming having seen versus imagined stimuli. Copyright (c) 2005 APA, all rights reserved.

  3. An Online Assessment of Personality, Psychological, and Sexuality Trait Variables Associated with Self-Reported Hypersexual Behavior.

    Science.gov (United States)

    Walton, Michael T; Cantor, James M; Lykins, Amy D

    2017-04-01

    "Hypersexual" behavior represents a perceived inability to control one's sexual behavior. To investigate hypersexual behavior, an international sample of 510 self-identified heterosexual, bisexual, and homosexual men and women completed an anonymous online self-report questionnaire battery. In addition to age and sex (male), hypersexual behavior was related to higher scores on measures of sexual excitation, sexual inhibition due to the threat of performance failure, trait impulsivity, and both depressed mood and anxiety. In contrast, hypersexual behavior was related to lower scores on sexual inhibition due to the threat of performance consequences. Higher neuroticism and extraversion, as well as lower agreeableness and conscientiousness, also predicted hypersexual behavior. Interestingly, interactions among the variables assessed did not significantly predict hypersexual behavior, suggesting the possible existence of multiple and predominantly independent taxa for various persons reporting hypersexual behavior. Core personality features may also be present in persons with hypersexual behavior. Clinical implications and future research directions are discussed.

  4. Help, I Am Losing Control! Examining the Reporting of Sexual Harassment by Adolescents to Social Networking Sites.

    2016-01-01

    Sexual harassment is often encountered by adolescents on social networking sites (SNS). One option to cope with a situation of harassment on SNS is to alarm the provider by reporting the transgressive content. It is yet unclear what the determinants of reporting a sexual harassment situation on SNS are, as well as the subsequent actions to these reports from the part of the SNS provider. In this article, we seek to address these gaps, and in particular examine whether control-by-the-self over the situation and negative emotions play a role in the reporting of sexual harassment on SNS. Findings indicate that a low situational control-by-the-self, indirectly (namely through a higher experience of negative emotions such as anger and shame) increases the reporting of sexual harassment by the victim. Public visibility of the incident and the impossibility to remove the content reduce the situational control-by-the-self. Results further suggest that SNS providers often ignore reported situations of sexual harassment. The study concludes with suggestions for responses to reported harassment on SNS, which should be directed toward increasing behavioral control and thereby alleviating negative emotions.

    Full Text Available Abstract: The lack of official data on rape has been a challenge for researchers in Brazil. Two recently published studies were based on law enforcement and medical records. Although these studies represent important progress in research on rape in the country, they have several limitations. In order to obtain more realistic rates, the current article reviews Brazilian studies on self-reported sexual aggression and victimization in individuals over 14 years of age. Forty-one studies were identified through electronic searches and reference verification. From 1% to 40% of women and 1% to 35% of men reported some form of victimization in the previous year. The male perpetration incidence ranged from 2% to 44%. Despite the wide variability, these rates were much higher than those provided by official data. The results suggest that sexual orientation is associated with vulnerability. Mixed findings were found concerning race. Most studies were based on convenience samples and focused on female victimization. Male victimization has received increasing attention, but studies on self-reported perpetration are still limited.

    2015-01-01

    Full Text Available Introduction: Our goal was to explore whether emergency department (ED patients would disclose their sexual orientation in a research evaluation and to examine demographic and clinical characteristics of patients by self-identified sexual orientation. Methods: Participants (n=177 presented for psychiatric treatment at three urban EDs in New York City, Rochester, NY, and Philadelphia, PA. Participants were interviewed in the context of a larger study of a standardized suicide risk assessment. We assessed participants’ willingness to answer questions regarding sexual orientation along three dimensions: a self-description of sexual orientation, a self-description of sexual attraction, and the gender of any prior sexual partners. Results: No participants (0/177 refused to respond to the categorical question about sexual orientation, 168/177 (94.9% agreed to provide information about prior sexual partners, and 100/109 (91.7% provided information about current sexual attraction toward either gender. Of all 177 participants, 154 (87.0% self-identified as heterosexual, 11 (6.2% as bisexual, 10 (5.6% as gay or lesbian, and 2 (1.1% indicated they were not sure. As compared with heterosexual patients, lesbian, gay and bisexual (LGB patients were significantly younger and more likely to be non-white, but did not differ significantly in terms of education, income, employment, or religious affiliation or participation. Further, LGB participants did not differ from self-identified heterosexual participants for lifetime suicide attempt rate or lifetime history of any mood, substance-related, psychotic spectrum, or other Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV Axis I disorder. Of self-identified heterosexual participants 5.6% (5/89 reported sexual attraction as other than ‘only opposite sex,’ and 10.3% (15/142 of sexually active ‘heterosexual’ participants reported previous same-gender sexual partners.

    Little is known about the association between self-reported academic performance and risky sexual behaviors and if this differs by gender, among university students. Academic performance can create psychological pressure in young students. Poor academic performance might thus potentially contribute to risky sexual behavior among university students. The aim of this study was to investigate the association between self-reported academic performance and risky sexual behaviors, and whether gender affects this relationship among Ugandan university students. In 2010, 1,954 students participated in a cross-sectional survey, conducted at Mbarara University of Science and Technology in southwestern Uganda (72% response rate). Multivariate logistic regression analysis was used for the analysis. 1,179 (60.3%) students in our study sample reported having debuted sexually. Of these 440 (42.2%) used condoms inconsistently with new sexual partners, and 344 (33.6%) had had multiple sexual partners. We found a statistically significant association between poor academic performance and inconsistent condom use with a new sex partner and this association remained significant even after adjusting for all the potential confounders. There was no such association detected regarding multiple sexual partners. We also found that gender modified the effect of poor academic performance on inconsistent condom use. Females, who were poor academic performers, were found to be at a higher risk of inconsistent condom use than their male counterparts. Interventions should be designed to provide extra support to poor academic performers, which may improve their performance and self-esteem, which in turn might reduce their risky sexual behaviors.

    This study assessed Kinsey self-ratings and lifetime sexual experiences of 17-year-olds whose lesbian mothers enrolled before these offspring were born in the longest-running, prospective study of same-sex parented families, with a 93% retention rate to date. Data for the current report were gathered through online questionnaires completed by 78 adolescent offspring (39 girls and 39 boys). The adolescents were asked if they had ever been abused and, if so, to specify by whom and the type of abuse (verbal, emotional, physical, or sexual). They were also asked to specify their sexual identity on the Kinsey scale, between exclusively heterosexual and exclusively homosexual. Lifetime sexual behavior was assessed through questions about heterosexual and same-sex contact, age of first sexual experience, contraception use, and pregnancy. The results revealed that there were no reports of physical or sexual victimization by a parent or other caregiver. Regarding sexual orientation, 18.9% of the adolescent girls and 2.7% of the adolescent boys self-rated in the bisexual spectrum, and 0% of girls and 5.4% of boys self-rated as predominantly-to-exclusively homosexual. When compared with age- and gender-matched adolescents of the National Survey of Family Growth, the study offspring were significantly older at the time of their first heterosexual contact, and the daughters of lesbian mothers were significantly more likely to have had same-sex contact. These findings suggest that adolescents reared in lesbian families are less likely than their peers to be victimized by a parent or other caregiver, and that daughters of lesbian mothers are more likely to engage in same-sex behavior and to identify as bisexual.

    Drug and alcohol use have been associated with increased risk for sexual violence, but there is little research on sexual violence within the context of drug use among young adult opioid users. The current mixed-methods study explores young adult opioid users' sexual experiences in the context of their drug use. Forty-six New York City young adults (ages 18-32) who reported lifetime nonmedical use of prescription opioids (POs) completed in-depth, semistructured interviews, and 164 (ages 18-29) who reported heroin and/or nonmedical PO use in the past 30 days completed structured assessments that inquired about their drug use and sexual behavior and included questions specific to sexual violence. Participants reported frequent incidents of sexual violence experienced both personally and by their opioid using peers. Participants described sexual violence, including sexual assault, as occurring within a context characterized by victimization of users who were unconscious as a result of substance use, implicit and explicit exchanges of sex for drugs and/or money that increased risk for sexual violence, negative sexual perceptions ascribed to drug users, and participants' own internalized stigma. Recommendations to reduce sexual violence among young adult opioid users include education for users and service providers on the risk of involvement in sexual violence within drug using contexts and efforts to challenge perceptions of acceptability regarding sexual violence.

    Research on sexual violence victims and perpetrators indicates that victims in general are found to report higher levels of psychopathological symptoms, especially internalizing behavior, whereas perpetrators often show externalizing behavior. Little is known, however, about the psychopathology of perpetrators of sexual violence who have also experienced sexual victimization (victim-perpetrators). Thus, the aim of the current study was to examine this group within a sample of adolescents living in residential care or federal boarding schools. Participants reported their lifetime experience with sexual violence (both as victim and perpetrator) and completed the Youth Self Report. Results indicate that all three groups of adolescents with sexual violence experience report higher total problem scores than adolescents without this experience. Victim-perpetrators show results more similar to those of perpetrators only than those of victims only. The discussion deals with the implications of our findings for the treatment of victims of sexual violence.

    According to betrayal trauma theory, adult survivors of childhood sexual abuse (CSA) who were molested by their caretakers (e.g., a father) are especially likely to dissociate ("repress") their memories of abuse. Testing college students, some reporting CSA, DePrince and Freyd (2004) found that those scoring high on a dissociation questionnaire exhibited memory deficits for trauma words when they viewed these words under divided-attention conditions. Replicating DePrince and Freyd's procedure, we tested for memory deficits for trauma words relative to neutral words in adults reporting either continuous or recovered memories of CSA versus adults denying a history of CSA. A memory deficit for trauma words under divided attention was expected in the recovered-memory group. Results were inconsistent with this prediction, as all three groups exhibited better recall of trauma words than neutral words, irrespective of encoding conditions.

    Emens, Elizabeth F

    2014-02-01

    Asexuality is an emerging identity category that challenges the common assumption that everyone is defined by some type of sexual attraction. Asexuals--those who report feeling no sexual attraction to others--constitute one percent of the population, according to one prominent study. In recent years, some individuals have begun to identify as asexual and to connect around their experiences interacting with a sexual society. Asexuality has also become a protected classification under the antidiscrimination law of one state and several localities, but legal scholarship has thus far neglected the subject. This Article introduces asexuality to the legal literature as a category of analysis, an object of empirical study, and a phenomenon of medical science. It then offers a close examination of the growing community of self-identified asexuals. Asexual identity has revealing intersections with the more familiar categories of gender, sexual orientation, and disability, and inspires new models for understanding sexuality. Thinking about asexuality also sheds light on our legal system. Ours is arguably a sexual law, predicated on the assumption that sex is important. This Article uses asexuality to develop a framework for identifying the ways that law privileges sexuality. Across various fields, these interactions include legal requirements of sexual activity, special carve-outs to shield sexuality from law, legal protections from others' sexuality, and legal protections for sexual identity. Applying this framework, the Article traces several ways that our sexual law burdens, and occasionally benefits, asexuals. This Article concludes by closely examining asexuality's prospects for broader inclusion into federal, state, and local antidiscrimination laws.

  4. Sexual narcissism and the perpetration of sexual aggression.

    Widman, Laura; McNulty, James K

    2010-08-01

    Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales-Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

    S V Subramanian

    Full Text Available BACKGROUND: Recent studies have emphasized the role of psychosocial stressors as a determinant of asthma, and neighborhoods can be a potential source of such stressors. We investigated the association between parental perception of neighborhood safety and reported lifetime asthma among children. METHODOLOGY/PRINCIPAL FINDINGS: Data for the study came from the 2003-04 National Survey of Children Health (NSCH; a nationally representative cross-sectional sample of children aged 0-17 years. Demographic, socioeconomic and behavioral covariates were included in the study. Models were estimated after taking account of weighting and complex survey design. Parental report of whether the child has ever been diagnosed with asthma by a physician was used to define the outcome. Parental report of perception of neighborhood safety was the main exposure. In unadjusted models, the odds ratio (OR for reporting asthma associated with living in neighborhoods that were perceived to be sometimes or never safe was 1.36 (95% confidence intervals [CI] 1.21, 1.53 compared to living in neighborhoods that were perceived to be always safe. Adjusting for covariates including exposure to second hand tobacco smoke, mother's self-rated health, child's physical activity and television viewing attenuated this association (OR 1.25, 95% CI 1.08, 1.43. In adjusted models, the increased odds ratio for reporting asthma was also higher among those who perceived neighborhoods as being usually safe (OR 1.15 95% CI 1.06, 1.26, as compared to always safe, suggestive of a dose-response relationship, with the differentials for usually safe and never safe being statistically significant (p = 0.009. CONCLUSION: Psychosocial stressors may be important risk factors that may impact the pathogenesis of asthma and/or contribute to asthma morbidity by triggering exacerbations through neuroimmunologic mechanisms, as well as social mechanisms.

    In previous studies, number of sexual partners and sexual assertiveness were examined as independent risk factors for sexual victimization among college women. Using a sample of 335 college women, this study examined the interaction of number of sexual partners and sexual assertiveness on verbal sexual coercion and rape. Approximately 32% of the sample reported unwanted sexual intercourse, 6.9% (n = 23) experienced verbal sexual coercion, 17.9% (n = 60) experienced rape, and 7.2% (n = 24) experienced both. As number of sexual partners increased, instances of verbal sexual coercion increased for women low in relational sexual assertiveness but not for women high in relational sexual assertiveness. A similar relationship was not found for rape. Among women who experienced both verbal sexual coercion and rape, increases in number of partners in the context of low refusal and relational assertiveness were associated with increases in verbal sexual coercion and rape. Findings suggest sexual assertiveness is related to fewer experiences of sexual coercion.

    Purpose To determine rates, patterns, and predictors of neurocognitive impairment in adults decades after treatment for childhood acute lymphoblastic leukemia (ALL). Patients and Methods Survivors of childhood ALL treated at St Jude Children's Research Hospital who were still alive at 10 or more years after diagnosis and were age ≥ 18 years were recruited for neurocognitive testing. In all, 1,014 survivors were eligible, 738 (72.8%) agreed to participate, and 567 (76.8%) of these were evaluated. Mean age was 33 years; mean time since diagnosis was 26 years. Medical record abstraction was performed for data on doses of cranial radiation therapy (CRT) and cumulative chemotherapy. Multivariable modeling was conducted and glmulti package was used to select the best model with minimum Akaike information criterion. Results Impairment rates across neurocognitive domains ranged from 28.6% to 58.9%, and those treated with chemotherapy only demonstrated increased impairment in all domains (all P values < .006). In survivors who received no CRT, dexamethasone was associated with impaired attention (relative risk [RR], 2.12; 95% CI, 1.11 to 4.03) and executive function (RR, 2.42; 95% CI, 1.20 to 4.91). The impact of CRT was dependent on young age at diagnosis for intelligence, academic, and memory functions. Risk for executive function problems increased with survival time in a CRT dose-dependent fashion. In all survivors, self-reported behavior problems increased by 5% (RR, 1.05; 95% CI, 1.01 to 1.09) with each year from diagnosis. Impairment was associated with reduced educational attainment and unemployment. Conclusion This study demonstrates persistent and significant neurocognitive impairment in adult survivors of childhood ALL and warrants ongoing monitoring of brain health to facilitate successful adult development and to detect early onset of decline as survivors mature.

    2013-01-01

    An investigation of narratives from the National Crime Victimization Survey (NCVS) finds that one in three teenagers--12-18 years old--who experience an unwanted sexual incident perpetrated by another teen trivialize their incidents as minor, unimportant, or normal kid stuff. This study contextualizes these responses within a framework of ambivalence that highlights separately teens' ambiguity of definitions, or uncertainty that incidents perpetrated by other teens (especially dating partners and schoolmates) are "real" crimes or offenses worth reporting, and adaptive indifference, a more tactical response to conflicting norms and allegiances that discourage teens from reporting their peers' sexual misconduct to authorities. The context and consequences of teens' ambivalence are discussed.

    Full Text Available Abstract Background The purpose of this study was to investigate the lifetime prevalence of teenage pregnancy in the histories of detained adolescent females and to examine the relationship between teenage pregnancy on the one hand and mental health and sexuality related characteristics on the other. Methods Of 256 admitted detained adolescent females aged 12–18 years, a representative sample (N = 212, 83% was examined in the first month of detention. Instruments included a semi-structured interview, standardized questionnaires and file information on pregnancy, sexuality related characteristics (sexual risk behavior, multiple sex partners, sexual trauma, lack of assertiveness in sexual issues and early maturity and mental health characteristics (conduct disorder, alcohol and drug use disorder and suicidality. Results Approximately 20% of the participants reported having been pregnant (before detention, although none had actually given birth. Sexuality related characteristics were more prevalent in the pregnancy group, while this was not so for the mental health characteristics. Age at assessment, early maturity, sexual risk behavior, and suicidality turned out to be the best predictors for pregnancy. Conclusion The lifetime prevalence of pregnancy in detained adolescent females is high and is associated with both sexuality related risk factors and mental health related risk factors. Therefore, prevention and intervention programs targeting sexual risk behavior and mental health are warranted during detention.

    South African women have disproportionately high rates of both sexual trauma and HIV. To understand how sexual trauma impacts HIV care engagement, we conducted in-depth qualitative interviews with 15 HIV-infected women with sexual trauma histories, recruited from a public clinic in Cape Town. Interviews explored trauma narratives, coping behaviors and care engagement, and transcripts were analyzed using a constant comparison method. Participants reported multiple and complex traumas across their lifetimes. Sexual trauma hindered HIV care engagement, especially immediately following HIV diagnosis, and there were indications that sexual trauma may interfere with future care engagement, via traumatic stress symptoms including avoidance. Disclosure of sexual trauma was limited; no women had disclosed to an HIV provider. Routine screening for sexual trauma in HIV care settings may help to identify individuals at risk of poor care engagement. Efficacious treatments are needed to address the psychological and behavioral sequelae of trauma.

    The aim of the current study is to gain a better insight into the relationship between sexually aggressive behaviour and psychopathy in youths; juveniles who sexually offended (JSOs) were compared with generally offending youths and a general population group. Seventy-one JSOs, 416 detained general offenders, and 331 males from the general population were assessed by means of the Youth Psychopathic traits Inventory (YPI), a self-report instrument. Sexually and generally offending juveniles had significantly lower levels of self-reported psychopathic traits than youths from the general population. Juvenile sexual offenders and generally offending juveniles did not differ in self-reported psychopathic traits. Furthermore, no differences in self-reported psychopathic traits were found between subgroups of JSOs (i.e., child molesters, solo offenders, and group offenders). The finding that self-reported psychopathic traits are less prevalent in offending juveniles than in general population youths raises questions about the usefulness of the YPI when comparing psychopathic traits between clinical samples and general-population samples.

    Abstract Purpose: Sexual minority (lesbian, gay, bisexual) populations have a higher prevalence of mental health and substance use disorders compared to their heterosexual counterparts. Such disparities have been attributed, in part, to minority stressors, including distal stressors such as discrimination. However, few studies have examined associations between discrimination, mental health, and substance use disorders by gender among sexual minority populations. Methods: We analyzed data from 577 adult men and women who self-identified as lesbian, gay, or bisexual and participated in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Six questions assessed discrimination due to sexual orientation. Weighted multivariable logistic regression examined associations between experiences of sexual orientation discrimination and both mental health and substance use disorders. Analyses were conducted separately for sexual minority men and women, adjusting for sociodemographic covariates. Results: Sexual minority men who ever experienced discrimination (57.4%) reported higher odds of any lifetime drug use disorder and cannabis use disorder compared to sexual minority men who never experienced discrimination. Sexual minority women who ever experienced discrimination (42.9%) reported higher odds of any lifetime mood disorder and any lifetime anxiety disorder compared to sexual minority women who never experienced discrimination. Conclusion: The findings suggest that discrimination is differentially associated with internalizing (mental health) and externalizing (substance use) disorders for sexual minority men and women. These findings indicate a need to consider how homophobia and heteronormative discrimination may contribute to distinct health outcomes for lesbian and bisexual women compared with gay and bisexual men.

    Full Text Available Sexual violence is not only a violation of human rights, but also a public health problem, with intimate partner violence and sexual violence among the most pervasive forms of violence against women. Worldwide, one in three women experience either physical or sexual partner violence or non-partner sexual violence. The lifetime prevalence of sexual partner violence reported by women, in age group of 15 to 49 years, in the WHO multi-country study ranged from 6% in Japan to 59% in Ethiopia, with rates in the majority of settings falling between 10% and 50%. The observed inter community; country and regional variation in the prevalence of violence imply that sexual violence within marriage can be addressed and preventable. The existing prevention programmes need to be tested and scaled up. The majority of women tend to avoid reporting these experiences due to associated shame, reprisal or gender inequity. Current review is an attempt to address the sexual violence among married women in a silent suffering. Various internets based popular search engines were used to explore data from literature, which includes PubMed, PubMed Central, Google Scholar and Medknow. Search was done using the key-word combinations and lsquo;sexual violence within marriage' and and lsquo;intimate partner violence'. A total of 51 publications were evaluated for this article.

    Current knowledge about risk factors for child sexual abuse and child pornography offenses is based on samples of convicted offenders, i.e., detected offenders. Only few studies focus on offenders not detected by the criminal justice system. In this study, a sample of 345 self-referred pedophiles and hebephiles was recruited from the community. All participants met DSM-IV-TR criteria for pedophilia or hebephilia (paraphilia not otherwise specified), were assured of confidentiality, and self-reported lifetime sexual offending against prepubescent and/or pubescent children. Two sets of group comparisons were conducted on self-report data of risk factors for sexual reoffending. Measures of risk factors address the following dimensions identified in samples of convicted offenders: sexual preferences (i.e. co-occurring paraphilias), sexual self-regulation problems, offense-supportive cognitions, diverse socio-affective deficits, and indicators of social functioning (e.g., education, employment). Men who admitted current or previous investigation or conviction by legal authorities (detected offenders) were compared with those who denied any detection for their sexual offenses against children (undetected offenders). Group comparisons (detected vs. undetected) were further conducted for each offense type separately (child pornography only offenders, child sexual abuse only offenders, mixed offenders). Although there were more similarities between undetected and detected offenders, selected measures of sexual-self regulation problems, socio-affective deficits, and social functioning data demonstrated group differences.

  18. Self-reported history of childhood smoking is associated with an increased risk for peripheral arterial disease independent of lifetime smoking burden.

    Full Text Available Atherosclerotic disorders are well known to be associated with obesity, lipid profile, smoking, hypertension and other medical comorbidities, and large cohort studies have explored the childhood correlates to these adult risk factors. However, there has been little investigation into the childhood risk factors for peripheral arterial disease (PAD. We endeavored to better understand the role of smoking in childhood in the risk for PAD in a well described cohort of 1,537 adults at high risk for cardiovascular disease. In a multivariate regression model, we observed an increased risk of PAD among those who reported a history of smoking during childhood (OR = 2.86; 95% CI, 1.99-4.11; P<0.001, which remained statistically significant after controlling for lifetime smoking burden (OR = 1.55; 95% CI, 1.00-2.41; P = 0.049. Our novel observation of disproportionate risk of PAD conferred by a history of childhood smoking may reflect an unrecognized biological mechanism such as a unique susceptibility to vascular injury or an unaccounted for covariate such as secondhand smoke exposure in childhood. This observation suggests further investigation is required into the pathophysiology of smoking in the developing vasculature and the need for detailed clinical data about patterns of childhood smoking and smoke exposure.

    2016-06-01

    Child sexual abuse is widespread and difficult to detect. To enhance case identification, many societies have enacted mandatory reporting laws requiring designated professionals, most often police, teachers, doctors and nurses, to report suspected cases to government child welfare agencies. Little research has explored the effects of introducing a reporting law on the number of reports made, and the outcomes of those reports. This study explored the impact of a new legislative mandatory reporting duty for child sexual abuse in the State of Western Australia over seven years. We analyzed data about numbers and outcomes of reports by mandated reporters, for periods before the law (2006-2008) and after the law (2009-2012). Results indicate that the number of reports by mandated reporters of suspected child sexual abuse increased by a factor of 3.7, from an annual mean of 662 in the three year pre-law period to 2448 in the four year post-law period. The increase in the first two post-law years was contextually and statistically significant. Report numbers stabilized in 2010-2012, at one report per 210 children. The number of investigated reports increased threefold, from an annual mean of 451 in the pre-law period to 1363 in the post-law period. Significant decline in the proportion of mandated reports that were investigated in the first two post-law years suggested the new level of reporting and investigative need exceeded what was anticipated. However, a subsequent significant increase restored the pre-law proportion, suggesting systemic adaptive capacity. The number of substantiated investigations doubled, from an annual mean of 160 in the pre-law period to 327 in the post-law period, indicating twice as many sexually abused children were being identified.

    Full Text Available Introduction In contrast to animal species in which linear relationships exist between hormonal status and sexual behaviour sexuality in human population is not determined so simply by the level of sexual steroids. The article analyses female sexuality in the light of hormonal status. Administration of sexual steroids during pregnancy and sexual differentiation High doses of gestagens, especially those with high androgen activity, widely used against miscarriages may lead to tomboys, but without differences in sexual orientation. However, it has been observed that the frequency of bisexual and lesbian women is higher in women with congenital adrenogenital syndrome. Hormones sexual desire and sexuality during menstrual cycle It has been established that sexual desire, autoeroticism and sexual fantasies in women depend on androgen levels. There are a lot of reports claiming that sexual desire varies during the menstrual cycle. Hormonal contraception and sexuality Most patients using birth control pills present with decreased libido. But, there are reports that progestagens with antiandrogenic effect in contraceptive pills do not affect sexual desire. Hormonal changes in peri- and postmenopausal period and sexuality Decreased levels of estrogen and testosterone in older women are associated with decreased libido, sensitivity and erotic stimuli. Sexuality and hormone replacement therapy Hormonal therapy with estrogen is efficient in reference to genital atrophy, but not to sexual desire. Really increased libido is achieved using androgens. Also, therapy with dehydroepiandrosterone (DHEA and tibolone have positive effects on female libido. Conclusion Effect of sexual steroids on sexual sphere of women is very complex. The association between hormones and sexuality is multidimensional, as several hormones are important in regulation of sexual behaviour. Still, it should be pointed out that sexuality is in the domain of hormonal, emotional

    2016-01-01

    This is the first study to report the prevalence of sexual violence perpetrated by a sport coach within a representative sample of the general population of adolescents aged between 14 and 17 years (N = 6 450). The questionnaire administered in high schools includes self-reported measures on a variety of dimensions relevant to the study of victimization, including sexual abuse, sexual contacts perceived as consensual, sexual harassment and involvement in an organized sport context. Descriptive and chi-square analyses were performed. The results show that 0.5% of adolescents experienced sexual abuse involving a coach. When considering all adolescents who experienced sexual abuse in their lifetime (10.2%), it appears that 5.3% of them were victims of sexual abuse by a coach. Participants also reported experiencing sexual harassment from a coach (0.4%) and consensual sexual contacts (1.2%) with a coach in the 12 months preceeding the study. Questions are raised on the overrepresentation of boys in situations of sexual victimization experiences in an organized sport context. PMID:25873593

    Although a large body of previous research has examined sexual behavior and its relation to risk in men of diverse sexual identities, most studies have relied on convenience sampling. As such, the vast majority of research on the sexual behaviors of gay and bisexual men, in particular, might not be generalizable to the general population of these men in the United States. This is of particular concern because many studies are based on samples of men recruited from relatively "high-risk" venues and environments. To provide nationally representative baseline rates for sexual behavior in heterosexual, gay, and bisexual men in the United States and compare findings on sexual behaviors, relationships, and other variables across subgroups. Data were obtained from the 2012 National Survey of Sexual Health and Behavior, which involved the administration of an online questionnaire to a nationally representative probability sample of women and men at least 18 years old in the United States, with oversampling of self-identified gay and bisexual men and women. Results from the male participants are included in this article. Measurements include demographic characteristics, particularly sexual identity, and their relations to diverse sexual behaviors, including masturbation, mutual masturbation, oral sex, vaginal sex, and anal sex. Behaviors with male and female partners were examined. Men of all self-identified sexual identities reported engaging in a range of sexual behaviors (solo and partnered). As in previous studies, sexual identity was not always congruent for gender of lifetime and recent sexual partners. Patterns of sexual behaviors and relationships vary among heterosexual, gay, and bisexual men. Several demographic characteristics, including age, were related to men's sexual behaviors. The results from this probability study highlight the diversity in men's sexual behaviors across sexual identities, and these data allow generalizability to the broader population of

Reporting guidelines, checklists and tools, irrespective of study design, applicable for reporting on programmes targeting SRH outcomes, were included. Two independent reviewers screened the title and abstract of all records. Full texts were assessed in duplicate, followed by data extraction on the focus, content area, year of publication, validation and description of reporting items. Data was synthesized using an iterative thematic approach, where items related to programme preparation, implementation and evaluation in each tool were extracted and aggregated into a consolidated list.Out of the 3,656 records screened for title and abstracts, full texts were retrieved for 182 articles, out of which 108 were excluded. Seventy-four full text articles corresponding to 45 reporting tools were retained for synthesis. The majority of tools were developed for reporting on intervention research (n = 15, randomized controlled trials (n = 8 and systematic reviews (n = 7.

    Aim The involvement of various penile structures in radiotherapy (RT)-induced sexual dysfunction among prostate cancer survivors remains unclear and domains beyond erectile dysfunction such as orgasm, and pain have typically not been considered. The purpose of this study was to investigate sexual dysfunction post-RT for localized prostate cancer and to examine whether radiation dose to different penile structures can explain these symptoms. Methods We investigated sexual dysfunction in two treated prostate cancer cohorts and in one non-pelvic-irradiated cohort, 328 sexually active men part of an unselected, population-based study conducted in 2008. The treated subjects were prescribed primary/salvage external-beam RT to 70 Gy@2.0 Gy/fraction. Absorbed RT doses (Dmean and Dmax) of the corpora cavernosa (CC), the penile bulb (PB), and the total penile structure (CC + PB) were related to 13 patient-reported symptoms on sexual dysfunction by means of factor analysis (FA) and logistic regression. Results Three distinct symptom domains were identified across all cohorts: “erectile dysfunction” (ED, two to five symptoms), “orgasmic dysfunction” (OD, two to four symptoms), and “pain” (two to three symptoms). The strongest predictor for ED symptoms was CC + PB Dmax (P = 0.001–0.03), CC and PB Dmean predicted OD symptoms equally well (P = 0.03 and 0.02–0.05, respectively), and the strongest predictor for pain symptoms was CC + PB Dmean (P = 0.02–0.03). Conclusion Sexual dysfunction following RT was separated into three main domains with symptoms related to erectile dysfunction, orgasmic dysfunction, and pain. Chances for intact sexual functionality may be increased if dose to the total penile structure can be restricted for these domains in the planning of RT. PMID:26564611

    Childhood sexual abuse (CSA) is associated with mood and cognitive deficits in children and young adults. Evidence suggests that the effects of early-life adversity persist throughout adulthood; however, the impact of CSA on cognition in older adults is largely unknown. This study investigated cognitive function in older adults with a reported history of CSA. Data are from a population-based study (The Irish Longitudinal Study on Ageing) of 6,912 adults aged 50 years and older. Participants answered questions about CSA as part of a stressful life events questionnaire. Global cognition, executive function, memory (both objective and self-rated), attention, and processing speed were measured via a comprehensive battery of tests. Anxiety and depression, other childhood adversity, health behaviours, chronic disease, and medication use were also assessed. Of the total sample, 6.5% reported CSA. These individuals were more likely to have experienced other forms of childhood adversity and to exhibit poor mental health compared to those who reported no history of CSA. Multivariate regression analyses revealed, however, that CSA was associated with better global cognition, memory, executive function, and processing speed, despite poorer psychological health in this group. Future studies should aim to investigate possible reasons for this finding.

    This paper presents an axiomatic framework for measuring life time poverty over multiple periods. For an individual, we argue that lifetime poverty is influenced by both the snapshot poverty of each period and the poverty level of the "permanent" lifetime consumption; it is also influenced by how poverty spells are distributed over the life time. Two obvious candidates for aggregation are to aggregate over time and then across individuals, or vice versa. For a society, we consider a path-inde...

    Sexuality research focuses almost exclusively on individuals rather than couples, though ongoing relationships are very important for most people and cultures. The present study was the first to examine sexual and relationship parameters of middle-aged and older couples in committed relationships of 1-51 years duration. Survey research was conducted in Brazil, Germany, Japan, Spain, and the U.S. targeting 200 men aged 40-70 and their female partners in each country, with 1,009 couples in the final sample. Key demographic, health, physical intimacy, sexual behavior, sexual function, and sexual history variables were used to model relationship happiness and sexual satisfaction. The median ages were 55 for men and 52 for women; median relationship duration was 25 years. Relationship satisfaction in men depended on health, physical intimacy, and sexual functioning, while in women only sexual functioning predicted relationship satisfaction. Models predicting sexual satisfaction included significant physical intimacy and sexual functioning for both genders and, for men, more frequent recent sexual activity and fewer lifetime partners. Longer relationship duration predicted greater relationship happiness and sexual satisfaction for men. However, women in relationships of 20 to 40 years were significantly less likely than men to report relationship happiness. Compared to men, women showed lower sexual satisfaction early in the relationship and greater sexual satisfaction later. Within the long-term committed relationship context, there were significant gender differences in correlates of sexual and relationship satisfaction, with sexual functioning a common predictor of both types of satisfaction and physical intimacy a more consistent and salient predictor for men.

    Mean excited-state lifetime is one of the fundamental fluorescence characteristics and enters as an important parameter into numerous calculations characterizing molecular interactions, such as e.g. FRET or fluorescence quenching. Our experiments demonstrated that the intensity-weighted mean fluorescence lifetime is very robust characteristic, in contrast to the amplitude-weighted one, which value is dependent on the data quality and particularly on the used fitting model. For the first time, we also report the procedure for the error estimation for both the intensity- and amplitude-weighted mean fluorescence lifetimes. Furthermore, we present a method for estimation of the mean fluorescence lifetime directly from the fluorescence-decay curve recorded by TCSPC (Time-Correlated Single-Photon Counting) method. For its simplicity and low computational demands, it could be a useful tool in the high-throughput applications, such as FACS, FLIM-FRET or HPLC detectors. - Highlights: Black-Right-Pointing-Pointer Intensity-weighted mean fluorescence lifetime is very robust characteristic.

    Full Text Available Adolescent sexual risk behavior can lead to serious health consequences, yet few investigations have addressed its neurodevelopmental mechanisms. Social neurocircuitry is postulated to underlie the development of risky sexual behavior, and response to social reward may be especially relevant. Typically developing adolescents (N = 47; 18M, 29F; 16.3 ± 1.4 years; 42.5% sexual intercourse experience completed a social reward fMRI task and reported their sexual risk behaviors (e.g., lifetime sexual partners on the Youth Risk Behavior Survey (YRBS. Neural response and functional connectivity to social reward were compared for adolescents with higher- and lower-risk sexual behavior. Adolescents with higher-risk sexual behaviors demonstrated increased activation in the right precuneus and the right temporoparietal junction during receipt of social reward. Adolescents with higher-risk sexual behaviors also demonstrated greater functional connectivity between the precuneus and the temporoparietal junction bilaterally, dorsal medial prefrontal cortex, and left anterior insula/ventrolateral prefrontal cortex. The greater activation and functional connectivity in self-referential, social reward, and affective processing regions among higher sexual risk adolescents underscores the importance of social influence underlying sexual risk behaviors. Furthermore, results suggest an orientation towards and sensitivity to social rewards among youth engaging in higher-risk sexual behavior, perhaps as a consequence of or vulnerability to such behavior.

    Despite the paramount importance of patient-reported outcomes, little is known about the evolution of patient-reported urinary and sexual function over time. To evaluate differences in pretreatment urinary and sexual function in two population-based cohorts of men with prostate cancer enrolled nearly 20 yr apart. Patients were enrolled in the Prostate Cancer Outcomes Study (PCOS) or the Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) study, two population-based cohorts that enrolled patients with incident prostate cancer from 1994 to 1995 and from 2011 to 2012, respectively. Participants completed surveys at baseline and various time points thereafter. We performed multivariable logistic and linear regression analysis to investigate differences in pretreatment function between studies. The study comprised 5469 men of whom 2334 (43%) were enrolled in PCOS and 3135 (57%) were enrolled in CEASAR. Self-reported urinary incontinence was higher in CEASAR compared with PCOS (7.7% vs 4.7%; adjusted odds ratio [OR]: 1.83; 95% confidence interval [CI], 1.39-2.43). Similarly, self-reported erectile dysfunction was more common among CEASAR participants (44.7% vs 24.0%) with an adjusted OR of 3.12 (95% CI, 2.68-3.64). Multivariable linear regression models revealed less favorable self-reported baseline function among CEASAR participants in the urinary incontinence and sexual function domains. The study is limited by its observational design and possibility of unmeasured confounding. Reporting of pretreatment urinary incontinence and erectile dysfunction has increased over the past two decades. These findings may reflect sociological changes including heightened media attention and direct-to-consumer marketing, among other potential explanations. Patient reporting of urinary and sexual function has evolved and is likely contingent on continually changing societal norms. Recognizing the evolving nature of patient reporting is essential in efforts to conduct

    To examine the prevalence of anabolic steroid misuse among US adolescent boys as a function of sexual orientation and race/ethnicity. We analyzed boys from the 2015 Youth Risk Behavior Survey (n = 6248; mean age = 16), a representative sample of US high school students. Lifetime prevalence of anabolic steroid misuse was dichotomized as never versus 1 or more times. Sexual minority boys reported elevated misuse compared with heterosexual boys, within each level of race/ethnicity. Black, Hispanic, and White sexual minority boys reported misuse at approximately 25%, 20%, and 9%, respectively. Sexual orientation health disparities in anabolic steroid misuse disproportionally affect Black and Hispanic sexual minority adolescent boys, but more research is needed to understand the mechanisms driving these disparities.

  1. VALIDITY AND CREDIBILITY OF A CHILD’S TESTIMONY OF SEXUAL ABUSE: A CASE REPORT

    Directory of Open Access Journals (Sweden)

    Antonina Argo

    2012-03-01

    Full Text Available The allegation by a child victim of sexual abuse is, in many cases, the most important evidence of wrongdoing, especially in absence of medical or physical evidence or confessions of guilt. The Rorschach inkblot test is a projective personality assessment technique used to evaluate child witnesses. We report a case of three girls allegedly abused by the father, in which the psychometric evaluation with the Rorschach test did not give credibility to the testimony of the children. When interrogating a minor, it is very difficult to distinguish between a true and a lie. Indeed, many different elements can affect the dialogue, such as the child’s age, the events being discussed, interrogation environment, factors linked to the interviewer, etc. Therefore, it is possible errors of evaluation, misunderstandings or confusion happen frequently. The aim of this case report is to highlight that employment of methodologies and criteria recognised by the scientific community could simplify the acquisition and assessment of information from a minor.

    Although street youth are at increased risk of lifetime pregnancy involvement (LPI), or ever becoming or getting someone pregnant, no reports to date describe the epidemiology of LPI among systematically sampled street youth from multiple cities outside of North America. The purpose of our assessment was to describe the prevalence of and risk factors associated with LPI among street youth from three Ukrainian cities. We used modified time-location sampling to conduct a cross-sectional assessment in Odesa, Kyiv, and Donetsk that included citywide mapping of 91 public venue locations frequented by street youth, random selection of 74 sites, and interviewing all eligible and consenting street youth aged 15-24 years found at sampled sites (n = 929). Characteristics of youth and prevalence of LPI overall and by demographic, social, sexual, and substance use risk factors, were estimated separately for males and females. Adjusted odds ratios (AORs) were calculated with multivariable logistic regression and effect modification by gender was examined. Most (96.6%) eligible youth consented to participate. LPI was reported for 41.7% of females (93/223) and 23.5% of males (166/706). For females, LPI was significantly elevated and highest (>70%) among those initiating sexual activity at ≤12 years and for those reporting lifetime anal sex and exchanging sex for goods. For males, LPI was significantly elevated and highest (>40%) among those who reported lifetime anal sex and history of a sexually transmitted infection. Overall, risk factors associated with LPI were similar for females and males. Among the total sample (females and males combined), significant independent risk factors with AORs ≥2.5 included female gender, being aged 20-24 years, having five to six total adverse childhood experiences, initiating sex at age ≤12 or 13-14 years, lifetime anal sex, most recent sex act unprotected, and lifetime exchange of sex for goods. Among street youth with LPI (n = 259), the

    Several recent reports have linked the use of dopamine agonists (DAs) to a variety of compulsive behaviors in patients with Parkinson's disease (PD). These inappropriate behaviors may include pathological gambling, compulsive shopping, and hypersexuality. To report the case of a patient with increased range of sexual behavior after use of pramipexole, a DA. A 67-year-old man with a 7-year diagnosis of PD treated with levodopa and pramipexole presented with a dramatic change in sexual behavior after an increase in DA dose. The patient, who historically was a very shy and conservative person, started to present increased frequency of sexual intercourse with his wife, during which he began speaking obscenities with an extreme preference for anal intercourse, preferences never requested before. After pramipexole was withdrawn, complete remission was observed with return to his usual sexual behavior. Hypersexuality and paraphilias are complications not uncommonly found in patients with PD under dopaminergic treatment. Further studies are needed for the understanding of this complex complication, and particularly the most prevalent relationship between pathological hypersexuality and use of DAs.

    Information about design, implementation, monitoring and evaluation is central to understand the impact of programmes within the field of sexual, reproductive, maternal, newborn, child and adolescent health (SRMNCAH). Existing reporting guidelines do not orient on reporting of contextual and implementation issues in sufficient detail. We therefore developed Programme Reporting Standards (PRS) to be used by SRMNCAH programme implementers and researchers. Building on the first step of the PRS development (a systematic review to identify reporting items), we conducted a three-round online Delphi consensus survey with experts. Consensus was defined a-priori as 80% agreement of items as essential. This was followed by a technical consultation with a group of experts to refine the items, definitions and their structuring. The revised PRS was piloted to assess its relevance to current SRMNCAH programme reports and identify key issues regarding the use of the PRS. Of the 81 participants invited to the Delphi survey, 20 responded to all three rounds. In the final round, 27 items received consensus as essential; three items were ranked as "borderline" essential; 20 items as supplementary. The items were subsequently revised, followed by a technical consultation with 29 experts to further review and refine the PRS. The feedback resulted in substantial changes to the structure and content of the PRS into 24 items across five domains: Programme overview; Programme components and implementation; Monitoring of Implementation; Evaluation and Results; and Synthesis. This version was used in a piloting exercise, where questions regarding how much information to report and how to comment on the quality of the information reported were addressed. All items were kept in the PRS following the pilot although minor changes were made to the flow and description of items. The PRS 1.0 is the result of a structured, collaborative process, including methods to incorporate input from SRMNCAH

    This study examined substance abuse treatment utilization across three dimensions of sexual orientation (identity, attraction, and behavior) in a large national sample of adults in the United States. Prevalence estimates were based on data collected from the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions. The sample consisted of 34,653 adults 20 years and older, and represented a population that was 52% women, 71% White, 12% Hispanic, 11% African American, 4% Asian, and 2% other race/ethnicities. An estimated 2% of the target population self-identified as lesbian, gay or bisexual; 4% reported same-sex sexual behavior, and 6% reported same-sex sexual attraction. Sexual minorities, especially women, had a greater likelihood of lifetime substance use disorders and earlier age of drinking onset. The majority of respondents with substance use disorders were untreated and lifetime substance abuse treatment utilization differed based on sexual orientation. Sexual minorities were found to have more extensive family histories of substance abuse problems. The findings indicate the underutilization of substance abuse treatment among all adults, and highlight some important factors to consider when working with sexual minorities.

    Clinicians have long associated depression with alterations in sexual function, predominantly loss of sexual interest. In a longitudinal study measuring self-report, behavioral, and nocturnal penile tumescence variables before and after treatment with cognitive behavior therapy in an unmedicated sample of 40 outpatient depressed men, we found, contrary to expectation, that sexual activity per se was not reduced during the depressed state. Rather, loss of sexual interest appeared to be related to the cognitive set of depression, ie, loss of sexual satisfaction that then improved with remission from depression. Depressed men were heterogeneous, however, with respect to sexual behavior, eg, an anxious and more chronically depressed subgroup of men who did not have remissions with cognitive behavior therapy reported increased sexual interest and sexual activity. Also, contrary to expectation, nocturnal penile tumescence abnormalities in depressed men did not reverse when measured in early remission, nor did nocturnal penile tumescence measures correlate significantly with behavioral measures of sexual function. Nocturnal penile tumescence alterations in depression may thus be similar to other persistent electroencephalographic sleep abnormalities seen in depressed patients in remission, in being more trait-like than statelike.

    The determinants of self-esteem have been little studied in non-clinic samples. It has been suggested recently that child sexual abuse (CSA) may be a major determinant of low self-esteem in adulthood. The psychosocial circumstances associated with low self-esteem in two random samples of women, one reporting CSA, the other not, were compared, with particular emphasis on characteristics of family of origin. A two-phase (postal-then-interview) random community study assessed self-esteem and related variables. Psychosocial variables predicting low self-esteem were the same in the two groups. They included being a follower or a loner, having an overcontrolling mother, being poorly qualified, giving a history of depressive disorder and displaying current psychiatric disorder. In addition, the subject's CSA status led to low self-esteem but only when it was of the most intrusive type. The CSA women had substantially lower mean total self-esteem score. However, not all aspects of self-esteem were diminished equally; 12/30 items differed between the two groups, and two of the five generated self-esteem factors, which we named Pessimism and Fatalism, which differed between the control group and the whole CSA group. There were no differences for Likeability and Determination. Predictors of low self-esteem for women include childhood temperament, a poor relationship with the mother, low qualification attainment, psychiatric morbidity, both previous and current, and, only when it is the most intrusive, CSA.

  16. Exploring the role of child sexual abuse and posttraumatic stress disorder symptoms in gay and bisexual men reporting compulsive sexual behavior.

    Compulsive sexual behavior (CSB) is an impairing yet understudied clinical phenomenon. The experience of child sexual abuse (CSA) has been implicated as an etiological factor in the development of some cases of CSB (Kuzma & Black, 2008); however, research regarding the role of CSA and related psychopathology in CSB symptomatology has been limited in the literature. The present study aimed to examine the uniqueness of the association of CSA with CSB as compared to other experiences of child maltreatment; the role of posttraumatic stress disorder (PTSD) symptomatology in CSB symptoms for individuals reporting CSA; and clinical differences between individuals with and without histories of CSA. Hypotheses were tested using data from a sample of 182 gay and bisexual men reporting CSB symptoms. CSA prevalence was high in the tested sample (39%). CSA severity was a unique predictor of CSB symptoms, above child physical and emotional abuse, and poly-victimization status was not significantly related to CSB symptoms. Contrary to hypotheses, PTSD symptoms did not significantly mediate the role of CSA severity, although PTSD symptoms explained additional variance in CSB symptoms, with the final model accounting for over a quarter of the variance in CSB symptoms (27%). Finally, men with a history of CSA reported more CSB, depressive, and anxious symptoms than those without a history of CSA. Findings from the present study support the hypothesis that CSA may be uniquely related to CSB symptoms, above other forms of child maltreatment, and indicate that men with a CSA history are likely to present more severe clinical comorbidities. Clinical implications and future research directions are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Background Women who have been in prison carry a greater lifetime risk of HIV for reasons that are not well understood. This effect is amplified in the Southeastern United States, where HIV incidence and prevalence is especially high among African American (AA) women. The role of consensual sexual partnerships in the context of HIV risk, especially same-sex partnerships, merits further exploration. Methods We conducted digitally recorded qualitative interviews with 29 AA women (15 HIV-positive, 14 HIV-negative) within three months after entry into the state prison system. We explored potential pre-incarceration HIV risk factors, including personal sexual practices. Two researchers thematically coded interview transcripts and a consensus committee reviewed coding. Results Women reported complex sexual risk profiles during the six months prior to incarceration, including sex with women as well as prior sexual partnerships with both men and women. Condom use with primary male partners was low and a history of transactional sex work was prevalent. These behaviors were linked to substance use, particularly among HIV-positive women. Conclusions Although women may not formally identify as bisexual or lesbian, sex with women was an important component of this cohort’s sexuality. Addressing condom use, heterogeneity of sexual practices, and partner concurrency among at-risk women should be considered for reducing HIV acquisition and preventing forward transmission in women with a history of incarceration.

    A review of the latest results on charm lifetimes and D-mixing is presented. The e+e- collider experiments are now able to measure charm lifetimes quite precisely, however comparisons with the latest results from fixed-target experiments show that possible systematic effects could be evident. The new D-mixing results from the B-factories have changed the picture that is emerging. Although the new world averaged value of y_CP is now consistent with zero, there is still a very interesting and favoured scenario if the strong phase difference between the Doubly-Cabibbo-suppressed and the Cabibbo-flavoured D0 -> Kpi decay is large.

    A cross-sectional survey of 298 pregnant women from Cape Town, South Africa was conducted to examine socio-demographic, reproductive health, mental health, and relationship correlates of lifetime trauma exposure and whether these correlates vary as a function of age. Overall, 19.8% of participants reported trauma exposure. We found similarities and differences in correlates of trauma exposure among women in emerging adulthood and older women. Prior termination of pregnancy was associated with trauma exposure in both age groups. Difficulties in resolving arguments, lifetime substance use, and a prior sexually transmitted infection were associated with trauma exposure among women in emerging adulthood. In contrast, depression and awareness of substance abuse treatment programmes were associated with trauma exposure among older women. These findings highlight the need for interventions that prevent and treat trauma exposure among vulnerable women. Such interventions should be tailored to address the correlates of trauma exposure in each age group.

    We sought to provide data-based estimates of sexual violence in the Democratic Republic of Congo (DRC) and describe risk factors for such violence. We used nationally representative household survey data from 3436 women selected to answer the domestic violence module who took part in the 2007 DRC Demographic and Health Survey along with population estimates to estimate levels of sexual violence. We used multivariate logistic regression to analyze correlates of sexual violence. Approximately 1.69 to 1.80 million women reported having been raped in their lifetime (with 407 397-433 785 women reporting having been raped in the preceding 12 months), and approximately 3.07 to 3.37 million women reported experiencing intimate partner sexual violence. Reports of sexual violence were largely independent of individual-level background factors. However, compared with women in Kinshasa, women in Nord-Kivu were significantly more likely to report all types of sexual violence. Not only is sexual violence more generalized than previously thought, but our findings suggest that future policies and programs should focus on abuse within families and eliminate the acceptance of and impunity surrounding sexual violence nationwide while also maintaining and enhancing efforts to stop militias from perpetrating rape.

  3. A review of sex differences in sexual jealousy, including self-report data, psychophysiological responses, interpersonal violence, and morbid jealousy.

    Science.gov (United States)

    2003-01-01

    The specific innate modular theory of jealousy hypothesizes that natural selection shaped sexual jealousy as a mechanism to prevent cuckoldry, and emotional jealousy as a mechanism to prevent resource loss. Therefore, men should be primarily jealous over a mate's sexual infidelity and women over a mate's emotional infidelity. Five lines of evidence have been offered as support: self-report responses, psychophysiological data, domestic violence (including spousal abuse and homicide), and morbid jealousy cases. This article reviews each line of evidence and finds only one hypothetical measure consistent with the hypothesis. This, however, is contradicted by a variety of other measures (including reported reactions to real infidelity). A meta-analysis of jealousy-inspired homicides, taking into account base rates for murder, found no evidence that jealousy disproportionately motivates men to kill. The findings are discussed from a social-cognitive theoretical perspective.

    Full Text Available Background: Sexual assault poses a serious health problem to both the survivor and the health system. Experiencing sexual assault requires women to seek medical and psychological assistance as part of their journey towards recovery. This study examined the experiences of women who received post-sexual assault services from a specialised care centre within a provincial hospital.Methods: A qualitative, exploratory and contextual design was used to explore and describe experiences of women. Data were obtained through individual in-depth interviews from a total of 18 women aged between 18 and 55 years. Interviews were supplemented by the researcher’s field notes and audiotape recordings.Results: Findings yielded two main themes: Women expressed their lived experiences of sexual assault characterised by different forms of trauma. The second theme was an expression of a need for safety and support.Conclusion: Women who experience sexual assault are left with devastating effects such as physical and psychological harm and social victimisation. There is also a need for safety and support towards the recovery of these women. This study recommends that professional practitioners involved in the management of sexual assault be sensitised regarding the ordeal experienced by women and stop perceiving survivors as crime scene ‘clients’ from whom only medico-legal evidence has to be collected. Professional practitioners and family members must be supportive, non-judgemental and considerate of the dignity of survivors. The establishment of sexual assault response teams (SART is also recommended. There should also be inter-professional education for better coordination of services rendered to sexually assaulted women.

    All available studies addressing the clinical and legal aspects of child pornography have systematically concerned male abusers. The social lens through which women are viewed tends to play down their responsibility in the sexual abuse of children. Unlike men, women rarely abuse children outside the close or family circle. Furthermore, they have frequently been abused themselves in their childhood. To our knowledge, no cases of women charged with sex-related offences, including child pornography, have been described in the literature. The psychopathological characteristics of female sexual abusers and of the two women in our cases tend to suggest that the deliberate downloading of child pornography images by women is unusual, as their deviant behaviour is not related to paedophile sexual arousal It is hypothesized that the act enables women perpetrators to satisfy the sexual urges of their spouse. Sexual abuse by women exists, but the nature of the abuse appears to be specific to the gender of the perpetrator. We present two cases of women charged with sexual offences concerning minors, including the production of child pornography material.

    Study Objective To determine associations between religiosity and female adolescents' sexual and contraceptive behaviors. Design We conducted a secondary analysis on data from a randomized controlled trial comparing interventions designed to prevent pregnancy and STDs. Multivariable modeling assessed the association between a religiosity index consisting of items related to religious behaviors and impact of religious beliefs on decisions and sexual outcomes. Participants 572 female adolescents aged 13 to 21, recruited via a hospital-based adolescent clinic and community-wide advertisements. Main Outcome Measures Sexual experience, pregnancy, STDs, number of lifetime partners, frequency of sexual activity, previous contraceptive use, and planned contraceptive use. Results Mean participant age was 17.4±2.2 years and 68% had been sexually active. Most (74.1%) had a religious affiliation and over half (52.8%) reported that their religious beliefs impact their decision to have sex at least “somewhat.” Multivariate analyses showed that, compared with those with low religiosity, those with high religiosity were less likely to have had sexual intercourse (OR=0.23, 95% CI=0.14, 0.39). Among sexually active participants, those with high religiosity were less likely to have been pregnant (OR=0.46, 95% CI=0.22, 0.97), to have had an STD (OR=0.42, 95% CI=0.22, 0.81), or to have had multiple (≥4) lifetime partners (OR=0.38, 95% CI=0.21, 0.68) compared to those with low religiosity. Levels of religiosity were not significantly associated with frequency of intercourse, contraception use at last intercourse, or planned contraceptive use. Conclusion In this cohort, religiosity appeared to be a protective factor rather than a risk factor with regard to sexual behavior and was not associated with contraception use. PMID:20493738

    The objectives of the study were to assess the prevalence of child sexual abuse (CSA) in a nation-wide representative sample of 14-17 year old Israeli adolescents, and to examine the associations between CSA, socio-demographic correlates and various measures of physical and mental health. The study population consisted of 906 mother-adolescent dyads, belonging to a community based, representative sample of Israeli 14-17 year olds, interviewed in 2004-5. Response rate was 68%. Subjects provided demographic data, and information about CSA, physical symptoms, body image, well-being and use of mental health services. DAWBA was used to obtain information regarding mental disorders and suicidality. SDQ was used to obtain data on bullying. Statistical analyses were conducted using an SPSS-17 complex sample analysis module and multivariate analyses were conducted to assess the associations between CSA and risk factors and social and health related correlates. Findings show that CSA was reported by 3.3% of adolescents. Higher risk of exposure to CSA was found among girls, among adolescents living in a one-parent household and among adolescents with a chronic disability. In multivariate models adjusting for gender, learning disabilities and depression, CSA was associated with suicidal attempts, stomach ache, dizziness, sleep problems, well being at home and bullying behaviors. No association was found with suicidal ideation or other physical symptoms. Our findings confirm that the associations between CSA and different outcomes vary depending on the socio-psychological context, and underline the importance of addressing the complexity of variables associated with CSA.

    Issue addressed: Unwanted sexual attention and unhealthy intimate relationships have the potential to have serious negative health consequences. To date, there has been scant focus on these issues among university students in Australia. The aim of the current study was to describe the extent of unwanted sexual attention and unhealthy intimate relationships experienced in their lifetime by female university students aged 18-25 years.Methods: A cross-sectional study was undertaken involving 465 female students aged 18-25 years. Students were recruited through one faculty within a Victorian university and invited to complete an anonymous online questionnaire.Results: Sixty-seven per cent (n = 312) of female students reported experiencing unwanted sexual attention in their lifetime. The most common form of unwanted sexual attention was kissing or touching over clothes (98%; n = 306). Over 43% (n = 124) of the female students reported that the experience of unwanted sexual experience occurred after their protests were ignored. Thirty per cent (n = 135) of the female students reported experiencing at least one element of an unhealthy intimate relationship.Conclusions: The high rates of unwanted sexual attention and unhealthy intimate relationships among female university students is of concern given the negative impact such events can have on individual's physical, emotional and social well being.So what?: Public health and health promotion action is required to prevent female students from experiencing unwanted sexual attention and unhealthy intimate relationships, and to address the negative health and well being consequences.

  12. History of child sexual abuse and adult sexual fantasies.

    Gold, S R

    1991-01-01

    The study investigated the hypothesis that women with a history of childhood sexual abuse would report different sexual fantasies from women with no childhood sexual abuse. Women with a history of abuse had more force in their fantasies, had more sexually explicit fantasies, began having sexual fantasies at a younger age, and had more fantasies with the theme of being under someone's control. Women with a history of childhood physical abuse did not have a similar pattern. It was suggested that the sexual fantasies may reflect the sexualizing effect of childhood sexual experiences and that fantasies of the abusive experience may become intrusive.

The period between ages 12–18 years is adolescence, during which crime rates are relatively high. The incidence of sexual behavior of adolescents on social media, which may be considered a crime, has increased in recent years due to technological improvements and increase in the use of social media. Also, the crime rates involving adolescents have increased due to environmental influences, familial factors, and mental disorders. Mental disorders such as conduct disorder, attention deficit hyperactivity disorder, and mood disorders have been found to be associated with sexual abuse in young persons in previous literature. In this study, we present the case of a boy who sexually abused his younger brother at the age of 14 years 2 months and broadcast this abuse on “Periscope”. In this case study, we aimed to discuss the relationships between sexual abuse, social media, and psychiatric disorders. Keywords: social media, child, sexual abuse

    A model describing the relationship between the ortho--positronium lifetime and the volume of a void, located in a synthetic zeolite, is analyzed. Our idea, which allows us to take into account the effects of temperature, comprises the introduction of a non--hermitian term in the Hamiltonian, which accounts for the annihilation of the ortho--positronium. The predictions of the present model are also confronted against an already known experimental result.

    Full Text Available Background. Sexual abuse may be associated with poorer weight loss outcomes following bariatric treatment. Identifying predictors of abuse would enable focused screening and may increase weight management success. Methods. We analyzed data from 500 consecutively recruited obese subjects from a population-based, regional bariatric program. The prevalence of self-reported sexual abuse was ascertained using a single interview question. Health status was measured using a visual analogue scale (VAS. Multivariable logistic regression was performed to identify sexual abuse predictors. Results. The mean age was 43.7 y (SD 9.6, 441 (88.2% were females, 458 (91.8% were white, and the mean body mass index (BMI was 47.9 kg/m2 (SD 8.1.

    2012-06-01

    Herein, we describe a case who presented with abnormal sexual behaviour during sleep. Video-electroencephalography monitoring during sleep revealed an abnormality suggesting an epileptic basis. The patient was successfully treated with carbamazepin. The psychiatric symptoms that were thought to be related to abnormal sexual behaviours were controlled with antipsychotic treatment. Our findings strongly emphasize the fact that efforts should be spent to increase awareness of seizure activity at night, which can be misinterpreted as benign parasomnias. Such a misinterpretation may have serious consequences, such as insufficient seizure control, progressive personality changes, and cognitive impairment.

    This report provides national estimates of sexual behavior, sexual attraction, and sexual orientation among women and men aged 18-44 in the United States, based on the 2011-2013 National Survey of Family Growth (NSFG). Data for the 2011-2013 NSFG were collected through in-person interviews with 10,416 women and men aged 15-44 in the household population in the United States. In this report, data are shown only for 9,175 adults aged 18-44. The data presented in this report were primarily collected using audio computer-assisted self-interviewing, in which the respondent enters his or her answers into the computer without telling them to an interviewer. The overall response rate for the 2011-2013 NSFG was 72.8%. Regarding opposite-sex sexual behavior, 94.2% of women and 92.0% of men aged 18-44 had ever had vaginal intercourse; 86.2% of women and 87.4% of men had ever had oral sex; and 35.9% of women and 42.3% of men had ever had anal sex. Almost three times as many women (17.4%) reported any same-sex contact in their lifetime compared with men (6.2%) aged 18-44. Feelings of attraction "only to the opposite sex" were more common for men (92.1%) compared with women (81.0%) aged 18-44. Among those aged 18-44, 92.3% of women and 95.1% of men said they were "heterosexual or straight"; 1.3% of women and 1.9% of men said they were "homosexual, gay, or lesbian"; 5.5% of women and 2.0% of men said they were bisexual; and 0.9% of women and 1.0% of men said "don't know" or "refused" (i.e., "did not report") on sexual orientation. Sexual attraction and sexual orientation correlate closely but not completely with reports of sexual behavior. Sexual behavior, sexual attraction, and sexual orientation vary by age, marital or cohabiting status, education, and race and Hispanic origin.

    The purpose of this study was to compare male and female college students in four countries (Canada, Germany, Sweden, and the U.S.) on their lifetime experiences (prevalence) and frequency of recent experiences with six types of online sexual activities (OSA): sexual information, sexual entertainment, sexual contacts, sexual minority communities, sexual products, and sex work. Participants (N = 2690; M age, 24.65 years; 53.4 % women, 46.6 % men) were recruited from a university in each of the countries to complete an online survey that included background and demographic questions, and questions about OSA. Most participants reported experience with accessing sexual information (89.8 %) and sexual entertainment (76.5 %) online. Almost half (48.5 %) reported browsing for sexual products, and a substantial minority reported having engaged in cybersex (30.8 %). Very few participants (1.1 %) paid for online sexual services or received payment (0.5 %). In general, participants showed relatively infrequent experience with all types of OSA within the last 3 months. Men showed both higher prevalence and frequency of use of sexually stimulating material online than did women. However, this gender gap was smaller than in previous studies. Country and gender by country effects were (with one exception) either very small or non-existent, suggesting that, overall, students in the four countries were similar in their OSA experiences. Results are discussed in light of an emerging global net generation and globalized sexual culture.

    Full Text Available Johan Vansintejan, Joris Janssen, Erwin Van De Vijver, Jan Vandevoorde, Dirk Devroey Department of Family Medicine, Vrije Universiteit Brussel (VUB, Brussels, Belgium Abstract: The aim of this Internet-based survey was to investigate the prevalence and associated predictors of sexual dysfunctions in Belgian self-reported HIV-positive men who have sex with other men. Of the 72 participants, 56% had a mild-to-severe erectile dysfunction, and 15% reported a hypoactive sexual desire disorder. The prevalence of premature ejaculation and anodyspareunia was 18% for both. Independent predictors for erectile dysfunction were frequency of masturbation, frequency of sex with partner, use of erectile enhancement drugs, having a passive sex role, and not having a steady relationship. Independent predictors for hypoactive sexual desire disorder were frequency of masturbation and having a lower lifetime number of sexual partners. Independent predictors for premature ejaculation were not having a steady relationship, having a lower lifetime number of sexual partners, and a lower level of education. The only independent predictor for anodyspareunia was having an active sex role. Keywords: homosexuality/male, sexual dysfunction, HIV, epidemiology

    Full Text Available Abstract Background Factors determining human sexual behaviour are not completely understood, but are important in the context of sexually transmitted disease epidemiology and prevention. Being obese is commonly associated with a reduced physical attractiveness but the associations between body mass index, sexual behaviour and the risk of acquiring sexually transmitted infections has never been studied. Methods The National Health and Nutrition Examination Survey (NHANES files of 1999–2000 were used. Linear regression was used to relate the reported number of sex partners in the last year and lifetime to Body Mass Index (BMI. Logistic regression was used to relate Herpes Simplex Virus type II (HSV-2 antibodies to BMI and other variables. Results Data on 979 men and 1250 women were available for analysis. Obese (mean number of partners for men:1.12, women: 0.93 and overweight (mean for men: 1.38, women: 1.03 individuals reported fewer partners than individuals of normal BMI (mean for men:2.00, women: 1.15 in the last year (p Conclusion Obese and overweight individuals, especially men, self report fewer sex partners than individuals of normal weight, but surprisingly this is not reflected in their risk of HSV-2 infection. HSV-2 antibodies provide information not contained in self-reported number of partners and may better estimate sexual risk than self-reported behaviour.

    Growing evidence documents elevated behavioral risk among sexual-minorities, including gay, lesbian, and bisexual individuals; however, tests of biological or psychological indicators of stress as explanations for these disparities have not been conducted. Data were from the 2005-2010 National Health and Nutrition Examination Survey, and included 9662 participants; 9254 heterosexuals, 153 gays/lesbians and 255 bisexuals. Associations between sexual orientation and tobacco, alcohol, substance, and marijuana use, and body mass index, were tested using the chi-square test. Stress, operationalized as depressive symptoms and elevated C-reactive protein, was tested as mediating the association between sexual orientation and behavioral health risks. Multiple logistic regression was used to test for mediation effects, and the Sobel test was used to evaluate the statistical significance of the meditating effect. Gays/lesbians and bisexuals were more likely to report current smoking (p sexual orientation and current smoking (aOR 2.04, 95% CI 1.59, 2.63), lifetime history of substance use (aOR 3.30 95% CI 2.20, 4.96), and lifetime history of marijuana use (aOR 2.90, 95% CI 2.02, 4.16), among bisexuals only. C-reactive protein did not mediate the sexual orientation/behavior relationship. Higher prevalence of current smoking and lifetime history of substance use was observed among sexual minorities compared to heterosexuals. Among bisexuals, depressive symptoms accounted for only 0.9-3% of the reduction in the association between sexual orientation and marijuana use and tobacco use, respectively. More comprehensive assessments of stress are needed to inform explanations of the disparities in behavioral risk observed among sexual minorities.

  4. Sexual Harassment Reported Among a Sample of Undergraduate Women in Physics

    The field of physics lags behind most other scientific fields in gender parity of students earning bachelor's degrees. The transition from enrollment in high school physics to graduating with physics degree represents the biggest decrease in the proportion of female students for any step in physics educational attainment. Sexual harassment contributes to an unwelcome climate. It is unknown how prevalent sexual harassment is in the field of physics and whether it's a contributing factor to the field's inability to recruit and retain female students. Our goal was to measure a quantitative baseline for sexual harassment--associated with physics--observed and experienced by a sample of female undergraduate students. As part of a larger conference evaluation survey, we conducted an internet-based survey (n = 632) of attendees of the APS Conference for Undergraduate Women in Physics to measure the extent to which they personally experienced or observed sexual harassment in a context associated with physics. We will present results from this survey. Opinions, findings, or conclusions expressed in this work do not necessarily reflect the views of the NSF, DOE, or APS.

    2010-01-01

    Full Text Available This paper results from an investigation on the discourse of female sexuality carried by women's magazines in the years 2005 and 2006. 'Claudia' and 'Mulher dia-a-dia' were the documents analyzed through a qualitative investigative approach. The data construction was undertaken through critical discourse analysis, and female sexuality was approached from a constructivist perspective. The main results showed that the discursive conventions present in the reports gave shape to dual positions on contemporary Western sexual dynamics, such as: adoption of symmetrical sexual practices versus continuation of asymmetrical sexual practices; female sexual autonomy versus female sexual dependency; activeness versus passiveness; female pleasure versus male pleasure. Thus, we argue that sexuality remains doubly informed by hegemonic standards in force within society.

    The absence of the father in the resident home is an increasing trend in the United States, and the belief that the absence of fathers is lined with a variety of social pathologies is gaining national momentum. This study explored the relationship of father absence on self-esteem and self-reported sexual activity among rural southern adolescents. A sample of 1,409 adolescents (558 males and 851 females) aged 11 to 18 years was surveyed, and the Miller Self-Esteem Questionnaire (MSQ) was used to measure self-esteem. Analysis revealed that increased sexual activity occurred by adolescents in homes where no father present in the residence. Although a statistical significance was noted in the relationship between father absence and lower self-esteem, the magnitude of the difference was not large. Further, no relationship between self-esteem and sexual activity was noted. Seemingly, the absence of the father has a potentially detrimental effect on adolescents' lifestyle choices. Consideration of the notion that the phenomena of fathering rather than the mere presence of a father may contribute to differences in adolescent's lifestyle choices should be studied.

    Full Text Available Abstract Background The incidence and prevalence of sexually transmitted infection (STI in China has been on the rise in the past decade. Delineation of epidemiologic pattern is often hampered by its uneven distribution. Spatial distribution is often a neglected aspect of STI research, the description of which may enhance epidemiologic surveillance and inform service development. Methods Over a one month-period, all first time attendees of 6 public STI clinics in Hong Kong were interviewed before clinical consultation using a standard questionnaire to assess their demographic, clinical and behavioural characteristics. A GIS (geographic information system-based approach was adopted with mapping performed. The cases attending the clinics in different locations were profiled. A comparison was made between neighbourhood cases (patients living near a clinic and distant cases (those farther off, by calculating the odds ratio for demographic, behavioural and geographic characteristics. Results Of the 1142 STI patients evaluated, the residence locations of 1029 (90.1% could be geocoded, of which 95.6% were ethnic Chinese and 63.4% male. Geographically only about a quarter lived in the same district as the clinic. STI patients aged 55 or above were more likely to be living in the vicinity of the clinic, located in the same or adjacent tertiary planning unit (a small geographic unit below district level. A majority of patients came from locations a few kilometers from the clinic, the distance of which varies between clinics. Overall, more syphilis cases were reported in patients residing in the same or adjacent tertiary planning unit, while distant cases tended to give a higher risk of inconsistent condom use. There were otherwise no significant clinical and epidemiologic differences between neighbourhood and distant STI cases. Conclusions There was no specific relationship between STI and the residence location of patients as regards their clinical and

    Sexual activity online may result in positive experiences for young people, or lead them to engage in risky behaviours possibly resulting in sexual assault or abuse. The aim of our study was to investigate associations between online sexual behaviours among Swedish youth and background factors as well as aspects of well-being. The behaviours investigated were: having sex online with a contact met online, having sex with an online contact offline, posting sexual pictures online, and selling sex online. We used data from a representative sample of 3,432 Swedish youth who were asked about their lifetime experiences as well as their experiences within the previous year. We hypothesized that more advanced online sexual behaviours were associated with more problematic background factors, worse psychosocial well-being and riskier behaviours in general. Bivariate relationships were evaluated followed by a multiple logistic regression model. Our data suggested that most Swedish youth do not perform any of the assessed online sexual behaviours. Young people who reported online sexual behaviour showed a more problematic background, rated their health as poorer, had a more sexualized life and had experienced more sexual or physical abuse. Professionals who work with young people need to help them better evaluate potential risks online and offer support when needed. Youths who sell sex online are especially at risk and need extra attention, as they might be in greater need of protection and therapeutic support.

    The purpose of this study was to examine the use of the internet to meet sexual partners among transgender individuals and examine correlates of this use, including sexual risk behavior, discrimination experiences, and mental health. A sample of 166 transgender adults (112 male-to-female transgender women and 54 female-to-male transgender men) were recruited in community venues and anonymously completed measures assessing these variables. Most participants (64.5 %) were HIV-negative, 25.2 % were HIV-positive, and 10.3 % did not know their HIV status. Overall, 33.7 % of participants reported having met a sexual partner over the internet, which did not differ significantly between transgender women and men. Among these individuals, transgender women reported significantly more lifetime internet sexual partners (median = 3) than transgender men (median = 1). Use of the internet to meet sexual partners was associated with lower self-esteem but not with depression, anxiety, somatic distress or discrimination experiences. Among transgender women, use of the internet to meet sexual partners was associated with each of the 11 sexual risk behaviors examined, including having multiple partners, sex under the influence of drugs, number of unprotected anal or vaginal sex acts, and history of commercial sex work. The use of the internet to meet partners was not associated with sexual risk behavior among transgender men (0/11 variables assessed). Although the internet is a common mode of meeting sexual partners among some transgender adults, it may also be a potential venue for prevention interventions targeting transgender individuals at particularly high risk for HIV acquisition.

    We investigated the implicit psychological and behavioral consequences of sexual abuse in an adolescent girl who suffered child sexual abuse at preschool age in this case report. We report the manifestations of this abuse on her personality and psychological functioning using a structured clinical interview and a comprehensive psychological battery including the Beck Anxiety Inventory, the Beck Depression Inventory, the Standard Progressive Matrices, Rorschach Ink Blots, and the Schema Mode Inventory. These investigations were useful in formulating both a diagnosis and a management plan. The girl fulfilled diagnostic criteria for a major depressive episode and borderline personality disorder. This combination of psychological testing may be useful in establishing an accurate multiaxial diagnosis and for understanding the behavioral and psychological sequelae of child sexual abuse in similar cases. The study further suggests that schema-focused therapy is a useful therapeutic tool for individuals who have suffered child sexual abuse at an early age and who have borderline personality disorder.

    More lesbian, gay, and bisexual (LGB) youths than heterosexuals report substance use. We examined a theoretical model to understand these disparities in lifetime and past-year substance use by means of stress and attachment paradigms, using the longitudinal Growing Up Today Study (GUTS) and Nurses' Health Study II (NHSII). GUTS participants are the children of participants in NHSII; thus, child and maternal data are available. In addition, GUTS contains siblings, allowing for comparisons of LGB and heterosexual siblings. Of 5,647 GUTS youths (M = 20.6 years old in 2005), 1.6% were lesbian/gay (LG), 1.6% bisexual (BI), 9.9% mostly heterosexual (MH), and 86.9% completely heterosexual (CH). After adjusting for sibling clustering in GUTS and covariates, significantly more sexual minorities (LGs, BIs, and MHs) than CHs reported lifetime and past-year smoking, nonmarijuana illicit drug use, and prescription drug misuse. More sexual minorities also reported marijuana use in the past year. The relations between sexual orientation and substance use were moderated by the stress markers: As mother's discomfort with homosexuality increased, more BIs and MHs than CHs used substances. As childhood gender nonconforming behaviors increased, more LGs than CHs used substances. The relations between sexual orientation and substance use were mediated by attachment and maternal affection (percent of effect mediated ranged from 5.6% to 16.8%% for lifetime substance use and 4.9% to 24.5% for past-year use). In addition, sibling comparisons found that sexual minorities reported more substance use, more childhood gender nonconforming behaviors, and less secure attachment than CH siblings; mothers reported less affection for their sexual minority than CH offspring. The findings indicate the importance of stress and attachment paradigms for understanding sexual-orientation disparities in substance use.

    HIV infection and psychiatric disorders have a complex relationship. HIV infection could lead to psychiatric disorders, and psychiatric patients are more vulnerable to HIV infection. HIV is not only an illness which is associated with stigmatization and discrimination, but also has several risks attached including physical and sexual abuse. There is a scarcity of literature on HIV, mental illness and sexual assault although they are a common trio. The author describes an HIV-positive woman with a psychiatric disorder. She suffered from AIDS and periodic psychotic epidsodes. On a day when she had such an episode she became a rape victim. The history, and physical and genital examination has been described. The need for further research in the area of HIV/AIDS and mental health has been discussed. Preventive strategies have been recommended for HIV-infected individuals in poor health resource settings.

    Kolya Uraltsev was one of the inventors of the Heavy Quark Expansion (HQE), that describes inclusive weak decays of hadrons containing heavy quarks and in particular lifetimes. Besides giving a pedagogic introduction to the subject, we review the development and the current status of the HQE, which just recently passed several non-trivial experimental tests with an unprecedented precision. In view of many new experimental results for lifetimes of heavy hadrons, we also update several theory predictions: $\\tau (B^+) / \\tau (B_d) = 1.04^{+0.05}_{-0.01} \\pm 0.02 \\pm 0.01$, $\\tau (B_s) / \\tau (B_d) = 1.001 \\pm 0.002$, $\\tau (\\Lambda_b)/ \\tau (B_d) = 0.935 \\pm 0.054$ and $\\bar {\\tau} (\\Xi_b^0) / \\bar{\\tau} (\\Xi_b^+) = 0.95 \\pm 0.06$. The theoretical precision is currently strongly limited by the unknown size of the non-perturbative matrix elements of four-quark operators, which could be determined with lattice simulations.

    This analysis assessed patterns of sexual experience, the order in which behaviors were initiated, and associated factors, among Latino and African American ninth grade students (average age 15.2) who self-administered audio-computer-assisted surveys on netbooks in classes at 10 Los Angeles-area public high schools. Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to report all three sexual behaviors versus vaginal only (odds ratios [ORs] 2.0, 1.5, 3.0; p = .02, .06, < .01, respectively). Although vaginal intercourse dominated their early sexual behavior, one-fifth of sexually experienced students reported anal intercourse, highlighting the need for specific prevention messages surrounding this higher-risk behavior.

    There are limited studies on the prevalence and correlates of sexual risk behavior among adolescents in Pacific Island countries. In order to inform public sexual and reproductive health interventions, the aim of this study was to assess the prevalence and correlates of various sexual risk behaviors among in-school adolescents in 4 Pacific Island countries using data from the Global School-Based Health Survey. In a cross-sectional study, 6792 school-going adolescents (49.7% boys and 50.3% girls; 13-16 years old) from Fiji, Kiribati, Samoa, and Vanuatu were surveyed with a self-administered questionnaire. Overall, 18.9% of students reported to ever had sex (ranging from 12.9% in Vanuatu to 57.5% in Samoa), and of those sexually active, 38.0% had an early sexual debut (<14 years), 38.1% had 2 or more sexual partners during their lifetime, 39.5% had not used a condom at last sex, 50.9% had not used birth control at last sex, and 77.8% engaged in sexually risky behavior using a composite measure. Multivariate logistic regression found that male sex, older age, tobacco use, alcohol use, mental distress, having no close friends, and truancy were associated with several of 5 or all 5 sexual risk behaviors. Sexual and reproductive health promotion programs are indicated to address the high risk of sexually transmitted infection, HIV, and pregnancy in this adolescent population.

    To examine the effect of patient defined non-regular sexual relationships and other risk behaviours on the incidence of sexually transmitted infections in heterosexual men and the role of condom use in the prevention of their spread. A prospective cross sectional study of sexual behaviour reported by a standardised self administered questionnaire in new patients who presented for screening and diagnosis. A genitourinary medicine clinic in west London. 957 consecutive newly attending heterosexual men who completed a sexual behaviour questionnaire in 1993/94. Variables relating to sociodemographic status, sexual behaviour, condom use, sexually transmitted infections and testing for HIV infection, stratified by the reporting of non-regular partners. We found that the 65% of men who reported non-regular sexual partners were more likely to be white collar class (d = 7.5%, 95% CI = 1.3, 13.7) and to have had sexual intercourse with non-United Kingdom born women (d = 7.8%, 95% CI = 3.5, 12.2). They also reported coitarche before 16 years of age (d = 13.4%, 95% CI = 8.0, 18.8) and many more sexual partners both in the last year (d = 13.1%, 95% CI = 10.2, 16.0) and in their lifetime (d = 27.9%, 95% CI = 21.6, 34.2). They were significantly more likely to practise anal intercourse (d = 8.7%, 95% CI = 3.3, 14.1), to smoke (d = 16.3%, 95% CI = 9.8, 22.6), to drink alcohol (d = 4.9%, 95% CI = 1.2, 8.6), and to have chlamydial infection (d = 5.7%, 95% CI = 2.2, 9.2), of which 30% was subclinical. Increasing condom use with regular partners correlated with decreasing incidence of urethral infection (gonorrhoeal and/or chlamydial infection) (p transmission of urethral gonorrhoea and chlamydial infection among men who reported always using condoms. HIV infection was found in only two men (0.2%), both of whom reported intercourse with non-United Kingdom born women. Heterosexual men who reported non-regular sexual relationships compensated for their increased risk lifestyle by using

    This study examines the implications of a history of personal violence on health and health behaviors. A secondary analysis of cross-sectional data involving adults (n = 214) from a semirural area in southern Louisiana between October 2008 and December 2010 was conducted to ascertain the association between a personal history of violence victimization and indicators of sexual health behaviors and outcomes: communication with sexual partners about HIV status, consistent condom use, and sexually transmitted infection (STI). While violence victimization is widely accepted as a risk factor for high-risk sex behavior, the mechanisms underlying violence victimization's influence on sexual health outcomes remain unclear. Bivariate analyses demonstrated a significant positive association between experience of physical abuse and lifetime history of STI. Surprisingly, respondents reporting lifetime physical violence were more than two times more likely to ask sexual partners about HIV status [odds ratio (OR) for physical attack = 2.23, 95% confidence intervals (CI) = 1.00-4.97; OR for physical injury = 4.60, 95% CI = 1.79-11.85]. Consistent condom use was not significantly associated with violence exposure in adjusted models. There was no evidence that communication with sexual partners mediated the relationship between experiences of violence and condom use. The link between personal history of violence and condom use may be mediated through alternative pathways beyond communication.

    This article explored the magnitude and nature of within marriage sexual violence against women and factors associated with physically forced sex by husbands in urban and rural Bangladesh using population-based survey data from 2001 (n = 2,702). Results showed high prevalence of lifetime sexual violence: 37 % in urban and 50 % in rural areas. An overwhelming majority of the women reported being sexually abused by husbands more than once. Logistic regression analyses revealed that six out of ten independent variables included in the models were significant. The factors positively associated with physically forced sex by husbands during the last 12 months were: history of physical abuse of husband's mother by his father; level of controlling behavior by husband; and forced or coerced first sex. Women's age (20-24 compared to 15-19) and dowry demand at marriage increased the likelihood of this violence in the rural area. Urban women in the second and third income quartiles were more likely to be exposed to this violence compared to women in the first quartile. Results highlight the need for prevention programs targeting men, which would help at the same time to break the cycle of intergenerational exposure and thereby transmission of violence. Notions of gender equality; women's sexual rights; and women's right to consent and choice need to be widely promoted particularly among men.

    This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders' paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims-suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample--sexual sadism and autoerotic asphyxiation--is explored from a historical and clinical perspective. Multiple commonalities shared between these five offenders and serial sexual murderers in general are addressed. A primary limitation of this study is its small sample size and empirical basis; the results may not be generalizable beyond the sample. The findings from this study support the supposition that crime scene behaviors often reflect paraphilic disturbances in those who commit serial sexual homicides.

    Background Sexually transmitted infections (STIs) are common among adolescents, and multiple STIs over one’s lifetime can increase health risks. Few studies have assessed lifetime STI prevalence. This study evaluates minority, underserved adolescents’ self-reported lifetime STI history and objective STI rates. Methods Lifetime STI rates of female patients at an urban adolescent health center were obtained from self-administered questionnaires. Additionally, STI test results were retrieved from electronic medical records. Results Patients reported a high lifetime prevalence of STIs. By comparing self-report and objective data, underreporting was identified for chlamydia, gonorrhea, and herpes. Conclusions STI rates in at-risk adolescent females are higher than in the general population and remain elevated over time. Lifetime STI reports could expand our understanding of sexual health and should be further studied. Underreporting, which may increase health risks and hinder health care delivery, requires further investigation. Improvements in STI screening and prevention targeting at-risk populations are warranted. PMID:24807980

    The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

    In preparation for the proposed conversion of the National Institute of Standards and Technology (NIST) research reactor (NBSR) from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel, certain point kinetics parameters must be calculated. We report here values of the prompt neutron lifetime that have been calculated using three independent methods. All three sets of calculations demonstrate that the prompt neutron lifetime is shorter for the LEU fuel when compared to the HEU fuel and longer for the equilibrium end-of-cycle (EOC) condition when compared to the equilibrium startup (SU) condition for both the HEU and LEU fuels.

  14. Sexual orientation disparities in sexually transmitted infections: examining the intersection between sexual identity and sexual behavior.

    The terms MSM (men who have sex with men) and WSW (women who have sex with women) have been used with increasing frequency in the public health literature to examine sexual orientation disparities in sexual health. These categories, however, do not allow researchers to examine potential differences in sexually transmitted infection (STI) risk by sexual orientation identity. Using data from the National Longitudinal Survey of Adolescent Health, this study investigated the relationship between self-reported STIs and both sexual orientation identity and sexual behaviors. Additionally, this study examined the mediating role of victimization and STI risk behaviors on the relationship between sexual orientation and self-reported STIs. STI risk was found to be elevated among heterosexual-WSW and bisexual women, whether they reported same-sex partners or not, whereas gay-identified WSW were less likely to report an STI compared to heterosexual women with opposite sex relationships only. Among males, heterosexual-identified MSM did not have a greater likelihood of reporting an STI diagnosis; rather, STI risk was concentrated among gay and bisexual identified men who reported both male and female sexual partners. STI risk behaviors mediated the STI disparities among both males and females, and victimization partially mediated STI disparities among female participants. These results suggest that relying solely on behavior-based categories, such as MSM and WSW, may mischaracterize STI disparities by sexual orientation.

    Adolescent sexual minority males (ASMM) comprise a high-risk group that may benefit from expanded human immunodeficiency virus (HIV) and sexually transmitted disease (STD) prevention services. The purpose of this study was to estimate the prevalence of HIV and STD testing among ASMM from pooled high school Youth Risk Behavior Surveys (YRBSs). Data came from 26 YRBSs from 2005 to 2013, which included questions on sexual identity and/or sex of sexual contacts and questions on ever being tested for HIV and/or STDs. Multivariable logistic regression was used to identify factors independently associated with lifetime HIV testing among sexually experienced ASMM. Overall, 3027 of 43,037 (6.3%, 95% confidence interval [CI]: 5.8%-6.8%) males were categorized as ASMM. Among 1229 sexually experienced ASMM, 413 (26.6%, 95% CI: 21.8%-31.4%) reported ever being tested for HIV, and among 571 ASMM who reported not using a condom during last intercourse, 192 (29.4%, 95% CI: 21.3%-37.6%) reported testing. A longer duration since first intercourse (≥3 vs. ≤1 year: adjusted prevalence ratio [aPR]: 1.6, 95% CI: 1.0-2.6) and recent intercourse (within the past 3 months vs. earlier: aPR: 2.2, 95% CI: 1.4-3.4) was associated with a higher adjusted prevalence of HIV testing. Sixty-four of 252 (30.2%, 95% CI: 20.0%-40.4%) sexually experienced ASMM reported ever being tested for STDs. Low levels of testing among sexually experienced ASMM, particularly those who reported sex without a condom at last intercourse, highlight the exigency of improving age-appropriate HIV and STD prevention services. Educating healthcare providers to better assess adolescent sexual histories is essential to increasing testing.

    Various forms of sexual violence including: Coerced marriage or wife inheritance, female genital mutilation, forced exposure to pornography, rape by intimate partner or strangers, unwanted sexual advances, and sexual abuse occurs, especially in vulnerable groups. However, most of these cases are not reported. The aim was to review reported cases in the facility, determine the prevalence and pattern of presentation. This was a prospective longitudinal study undertaken at the Gynecological Emergency Unit of a Tertiary Health Facility in a rural setting Northwest Nigeria. A study of survivors of alleged sexual violence who presented to the hospital from the September 1, 2011 to August 31, 2013. During the study period, there were 24 cases of sexual violence (22 were alleged rape and 2 were others) of 973 gynecological consultations at the emergency unit, giving a prevalence of 3% (24/973) for sexual violence and 2.3% (22/973) for alleged rape. Majority 91.7% (22/24) of the cases were children violence in this facility was low with the majority of the survivors being children and nonstranger assailants', mostly neighbors.

The authors sampled pregnant women (N = 215) from outpatients registered at the antepartum clinic of a medical center in northern Taiwan. The authors gathered data on recent sexual satisfaction, general sexual satisfaction, and sexual position using a self-report, structured questionnaire. The results showed that coital frequency decreased from the first to third trimester (p sexual position for pregnant women (67.6%) was man on top, face-to-face. Sexual position did not change significantly by trimester. More women with more sexual satisfaction than women with poor sexual satisfaction tended to adopt the woman-on-top, face-to-face, and abdominal-supportive sexual positions.

    The purpose of this clinical report is to provide pediatricians updated research on evidence-based sexual and reproductive health education conducted since the original clinical report on the subject was published by the American Academy of Pediatrics in 2001. Sexuality education is defined as teaching about human sexuality, including intimate relationships, human sexual anatomy, sexual reproduction, sexually transmitted infections, sexual activity, sexual orientation, gender identity, abstinence, contraception, and reproductive rights and responsibilities. Developmentally appropriate and evidence-based education about human sexuality and sexual reproduction over time provided by pediatricians, schools, other professionals, and parents is important to help children and adolescents make informed, positive, and safe choices about healthy relationships, responsible sexual activity, and their reproductive health. Sexuality education has been shown to help to prevent and reduce the risks of adolescent pregnancy, HIV, and sexually transmitted infections for children and adolescents with and without chronic health conditions and disabilities in the United States.

    This is Phase II of a three-phase study for the development of high performance refractory fibers with enhanced insulating properties and longer service lifetimes, for use in the aluminum, glass, cement, and iron and steel industries. Fiberization of 24 out of 25 compositions in the Al{sub 2}O{sub 3}-Si0{sub 2}-Zr0{sub 2} system were achieved. These 24 and three existing fiber compositions were evaluated: The shrinkage and the crystalline and vitreous phases were determined vs heat treatment time and temperature. Four theoretical models were developed: Shrinkage, devitrification kinetics, density change, and fiberization. Although some of the fibers formed during Phase II had properties as good as the reference ASZ fiber, no fiber had a significantly improved performance. This work, although not entirely successful, did produce significant benefits to refractory insulating fiber manufacturers and users: Mechanisms of both linear and thickness shrinkage for vitreous refractory fibers were determined, devitrification kinetics were quantified and used in models to predict shrinkage during service, and the mechanism of fiber formation in the melt spinning process was studied.

    2016-12-01

    Photoacoustic (PA) imaging has been utilized to quantify the lifetime profile of exogenous agents using a series of pump-probe pulses with a varying time delay; however, current techniques typically lead to long acquisition times which are sensitive to motion and cause absorption or photobleaching. We introduce a technique called lifetime-weighted imaging, which uses only three laser pulses to preferentially weight signals from chromophores with long lifetimes (including exogenous contrast agents with triplet excited states such as methylene blue and porphyrins) while nulling chromophores with short picosecond- to nanosecond-scale lifetimes (including hemoglobin). This technique detects the PA signal from a probe pulse either with or without a pump pulse. By subtracting the probe-only signal from the pump-present probe signal, we effectively eliminate signals from chromophores with short lifetimes while preserving PA signals from chromophores with long-lifetimes. We demonstrate the oxygen-dependent lifetime of both methylene blue and porphyrin-lipids and demonstrate both ground-state recovery and excited-state lifetime-weighted imaging. Lifetime-weighted PA imaging may have applications in many molecular imaging application including: photodynamic therapy dosimetry guidance and oxygen sensing.

    This technical brief explains the concepts of energy savings lifetimes and savings persistence and discusses how program administrators use these factors to calculate savings for efficiency measures, programs and portfolios. Savings lifetime is the length of time that one or more energy efficiency measures or activities save energy, and savings persistence is the change in savings throughout the functional life of a given efficiency measure or activity. Savings lifetimes are essential for assessing the lifecycle benefits and cost effectiveness of efficiency activities and for forecasting loads in resource planning. The brief also provides estimates of savings lifetimes derived from a national collection of costs and savings for electric efficiency programs and portfolios.

    The life insurance industry is very interested in how a person's lifetime is related to his wealth with financial advisors interested in how even a person's portfolio choice affects his lifetime. This paper presents a statistical analysis combined with intuitive relationships between lifetime and wealth. Key properties of this relationship are given and then various copulas are analyzed to see whether they have these properties. Other advantages and disadvantages of these copulas for describing the dependence are stated. The results show that some copulas are not appropriate for relating lifetime and wealth, including the Gaussian family.

    The number of categorical sexually transmitted disease (STD) clinics is declining in the United States. Federally qualified health centers (FQHCs) have the potential to supplement the needed sexually transmitted infection (STI) services. In this study, we describe the spatial distribution of FQHC sites and determine if reported county-level nonviral STI morbidity were associated with having FQHC(s) using spatial regression techniques. We extracted map data from the Health Resources and Services Administration data warehouse on FQHCs (ie, geocoded health care service delivery [HCSD] sites) and extracted county-level data on the reported rates of chlamydia, gonorrhea and, primary and secondary (P&S) syphilis (2008-2012) from surveillance data. A 3-equation seemingly unrelated regression estimation procedure (with a spatial regression specification that controlled for county-level multiyear (2008-2012) demographic and socioeconomic factors) was used to determine the association between reported county-level STI morbidity and HCSD sites. Counties with HCSD sites had higher STI, poverty, unemployment, and violent crime rates than counties with no HCSD sites (P < 0.05). The number of HCSD sites was associated (P < 0.01) with increases in the temporally smoothed rates of chlamydia, gonorrhea, and P&S syphilis, but there was no significant association between the number of HCSD per 100,000 population and reported STI rates. There is a positive association between STI morbidity and the number of HCSD sites; however, this association does not exist when adjusting by population size. Further work may determine the extent to which HCSD sites can meet unmet needs for safety net STI services.

    Although understanding chlamydia incidence assists prevention and control, analyses based on diagnosed infections may distort the findings. Therefore, we determined incidence and examined risks in a birth cohort based on self-reports and serology. Self-reported chlamydia and behavior data were collected from a cohort born in New Zealand in 1972/3 on several occasions to age 38 years. Sera drawn at ages 26, 32, and 38 years were tested for antibodies to Chlamydia trachomatis Pgp3 antigen using a recently developed assay, more sensitive in women (82.9%) than men (54.4%). Chlamydia incidence by age period (first coitus to age 26, 26-32, and 32-38 years) was calculated combining self-reports and serostatus and risk factors investigated by Poisson regression. By age 38 years, 32.7% of women and 20.9% of men had seroconverted or self-reported a diagnosis. The highest incidence rate was to age 26, 32.7 and 18.4 years per 1000 person-years for women and men, respectively. Incidence rates increased substantially with increasing number of sexual partners. After adjusting age period incidence rates for partner numbers, a relationship with age was not detected until 32 to 38 years, and then only for women. Chlamydia was common in this cohort by age 38, despite the moderate incidence rates by age period. The strongest risk factor for incident infection was the number of sexual partners. Age, up to 32 years, was not an independent factor after accounting for partner numbers, and then only for women. Behavior is more important than age when considering prevention strategies.

    Full Text Available Little information exists on U.S. physicians who have been disciplined with licensure or restriction-of-clinical-privileges actions or have had malpractice payments because of sexual misconduct. Our objectives were to: (1 determine the number of these physicians and compare their age groups' distribution with that of the general U.S. physician population; (2 compare the type of disciplinary actions taken against these physicians with actions taken against physicians disciplined for other offenses; (3 compare the characteristics and type of injury among victims of these physicians with those of victims in reports for physicians with other offenses in malpractice-payment reports; and (4 determine the percentages of physicians with clinical-privileges or malpractice-payment reports due to sexual misconduct who were not disciplined by medical boards.We conducted a cross-sectional analysis of physician reports submitted to the National Practitioner Data Bank (NPDB from January 1, 2003, through September 30, 2013. A total of 1039 physicians had ≥ 1 sexual-misconduct-related reports. The majority (75.6% had only licensure reports, and 90.1% were 40 or older. For victims in malpractice-payment reports, 87.4% were female, and "emotional injury only" was the predominant type of injury. We found a higher percentage of serious licensure actions and clinical-privileges revocations in sexual-misconduct-related reports than in reports for other offenses (89.0% vs 68.1%, P = < .001, and 29.3% vs 18.8%, P = .002, respectively. Seventy percent of the physicians with a clinical-privileges or malpractice-payment report due to sexual misconduct were not disciplined by medical boards for this problem.A small number of physicians were reported to the NPDB because of sexual misconduct. It is concerning that a majority of the physicians with a clinical-privileges action or malpractice-payment report due to sexual misconduct were not disciplined by medical boards for

    The gas plant at Kaarstoe was built as part of the Statpipe gas transport system and went on stream in 1985. In 1993 another line was routed from the Sleipner field to carry condensate, and the plant was extended accordingly. Today heavy additional supply- and export lines are under construction, and the plant is extended more than ever. The main role of the factory is to separate the raw gas into commercial products and to pump or ship it to the markets. The site covers a large number of well-known mechanical equipment. This presentation deals with piping, mechanical and structural disciplines. The lifetime of mechanical equipment is often difficult to predict as it depends on many factors, and the subject is complex. Mechanical equipment has been kept in-house, which provides detailed knowledge of the stages from a new to a 14 years old plant. The production regularity has always been very high, as required. The standard of the equipment is well kept, support systems are efficient, and human improvisation is extremely valuable.

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

    Health care providers must recognize the specific challenges and rewards of providing services for adolescents. Quality care begins with the establishment of trust, respect, and confidentiality between the health care provider and the adolescent. Data suggest that the normal age for beginning puberty is decreasing, which has important clinical, educational, and social implications. The health care provider should be aware of the broad range of potential sexual behaviors involving adolescents, as well as the teen's acceptance of such behaviors, often dictated by age, gender, culture, and education. When providing gynecologic care to adolescent girls, the physician should not only provide contraception and screen for sexually transmitted diseases but should contribute to the development of the patient's sexual health. Especially when providing care for the younger teen, the health care provider must focus on involving a member of the family or another significant adult to provide needed support and guidance. Anticipatory guidance for parents should focus on assessing their parenting styles and promoting supervision. Although parents should strive to maintain open communication with their adolescents, they may not accurately estimate the sexual activity of and the sexual risk for their teenage children. Parents need to be encouraged to consider the implications of their own sexual behaviors. The provider should attempt to foster a comfortable environment in which youth may seek help and support for appropriate medical care while reserving the right to disclose their sexual identity when ready. Health care professionals cannot exclude heterosexual behavior on the basis that a young woman self-identifies as homosexual. Her reported sexual behaviors may not indicate her sexual orientation. Self-definition of sexual orientation is a dynamic process including factors such as fantasies, desires, and behaviors. Self-definition of sexual identity is affected by individual

    This study examined the motivations for entering the field and sexual attitudes, experiences, and behavior of an international group of sexuality professionals. Participants were 252 individuals attending the XVII World Congress of Sexology who completed a questionnaire in English, Spanish or French. Most participants' reported professional rather than personal motivations for entering the field in addition to interest. On average, participants reported little sexual communication with their parents as children. About one-third had experienced unwanted sexual activity as a child. Participants were mostly accepting of a range of sexual activities, although they were less accepting of some behaviors than of others. Twelve of the participants who had engaged in sexual activity with a casual or anonymous partner in the previous 2 years had not used a condom consistently. Participants reported high sexual satisfaction and good sexual communication with their partner. Nevertheless, 45% of the women and 35% of the men reported regularly experiencing one or more sexual problems. Few participants reported that their profession affected their sexual functioning negatively; in contrast most reported that it had positive effects on their sexual functioning. These results suggest that there are few differences between sexuality professionals and the general public.

    This study examined the prevalence and correlates associated with lifetime and recent violence among a sample of harder-to-reach human immunodeficiency virus (HIV)-positive women living in British Columbia (BC), Canada. Interviewer-led surveys with 1000 participants gathered quantitative data on social, economic, and structural characteristics such as housing status, relationship status, family structure, history of drug use, and sexual behavior. Logistic regression analysis modeled associations between independent variables and experiences of violence at baseline. Cox regression analyses with time-dependent covariates determined correlates of lifetime and recent violence among HIV-positive women. Of the 249 women in the study, an overwhelming proportion of women (81%) reported experiences of violence in their lifetime. Among those, 22% reported recent experiences of violence, and 56% of the women reported more than five violent episodes in their lifetime. Lifetime violence was independently associated with HIV-related stigma (adjusted odds ratio [AOR] = 2.18, 95% confidence interval [CI] = 1.14-5.70), previous tobacco use (AOR = 2.79, 95% CI = 1.10-7.07), ever having a drinking problem (AOR = 2.82, 95% CI = 1.28-6.23), and ever having received care for a mental health condition (AOR = 2.42, 95% CI = 1.06-5.52). Recent violence was associated with the current illicit drug use (AOR = 2.60, 95% CI = 1.14-5.90), and currently residing in unstable housing (AOR = 2.75, 95% CI = 1.31-5.78). This study underscores the need to consider potential experiences of historical and current violence as part of comprehensive care for women living with HIV.

  3. The role of fantasy in a serial sexual offender: a brief review of the literature and a case report.

    2011-01-01

    Extensive research has attempted to elucidate the role of fantasy in sexual offending. In this paper, the authors summarize the main results of the literature, especially the contents, themes, dynamics, etiopathogenesis, and potential functions of fantasy in sexual offending. Further, the authors analyze the case of a serial sexual offender who assaulted 39 women. The forensic-psychiatric assessment revealed that his fantasies of forced sex, sexual coercion, and dominance, which were linked to narcissistic personality organization and functioning, were the primary drive mechanism in his crimes, because he imagined himself in the role of the aggressor, identified with the power associated with the role of perpetrator, and was sexually aroused by such images of omnipotent control of the victim. In conclusions, the authors suggest that fantasies of sexual aggression, coercion, and dominance of women may stimulate grandiosity and omnipotence and, in a minority of cases, may lead to sexual offending.

  4. Force in women's sexual fantasies.

    1998-08-01

    Attitudinal and experiential correlates of sexual fantasies involving force or coercion against the fantasizer were studied in 137 college women. Results revealed that (i) virtually every woman reported engaging in sexual fantasy on a regular basis, (ii) more than half the subjects reported having engaged in a force fantasy, (iii) those reporting force fantasies scored as less sexually guilty and more erotophilic than those not reporting such fantasies. Those reporting force fantasies also had more sexual experience and engaged in more fantasizing of the nonforce type than the other subjects. A history of exposure to sexual force or coercion was unrelated to the report of force fantasies. Taken together, these findings are offered in support of the hypothesis that the occurrence of force fantasies, rather than resulting from an attempt to deal with sexual guilt, represents one of a number of ways in which some women demonstrate a relatively open, unrestricted, and varied approach to their sexuality.

    Violence is what the victims experience as violence. Only they are able to measure what oppression, injury, pain or sexual violence can cause. Violence starts where human beings are constrained, humiliated, abjected and injured in their self-determination by other human beings. The experienced violence causes a trauma in most cases and in many cases also a PTSD. As a lot of epidemiological studies have affirmed, the highest lifetime-prevalence of PTSD appears after one respectively after a repeated act of sexual violence.It is important to define the circumstances of the action, by defining three fields of violence: domestic sexual violence, sexual violence in civil everyday life respectively violence, that occurs not inside families and sexual violence in wartime.Victims of all fields of violence can be found in Western Europe, the last mentioned form of violence predominant among refugees, but also among survivors of the last world war.

    Despite research documenting disparities in risk for alcohol-related problems among sexual minority women, few studies explore potential protective factors within this population. This study examines how religiosity may function as a protective or risk factor for alcohol-problems or other substance use among sexual minorities compared to heterosexuals. Data from 11,169 women who responded to sexual identity and sexual behavior questions from three population-based National Alcohol Survey waves (2000, 2005, 2010) were utilized for analyses of religiosity in relation to lifetime drinking, past year hazardous drinking, and past year drug use. Religiosity was significantly greater among exclusively heterosexual women compared to all sexual minority groups (lesbian, bisexual and heterosexual women who report same sex partners). Lesbians reported the lowest rates of affiliation with religions/denominations discouraging alcohol use. Past year hazardous drinking and use of any illicit drugs were significantly lower among exclusively heterosexual women compared to all sexual minority groups. High religiosity was associated with lifetime alcohol abstention and was found to be protective against hazardous drinking and drug use among both sexual minority and heterosexual women. Reporting religious norms unfavorable to drinking was protective against hazardous drinking among exclusively heterosexual women but not sexual minority women. Findings reveal the importance of considering sexual minority status in evaluation of religion or spirituality as protective among women. Future studies should explore religiosity in the context of other individual and environmental factors, such as positive identity development and community-level acceptance, which may be salient to resiliency among sexual minorities.

    There is growing interest in understanding human papillomavirus (HPV) infection and related disease among men. To date there have been numerous studies reporting HPV DNA prevalence among men from several different countries, however, few have incorporated multivariable analyses to determine factors independently associated with male HPV detection. The purpose of this study was to assess the factors independently associated with HPV detection in men ages 18-70 years residing in Brazil (n = 343), Mexico (n = 312), and the United States (US) (n = 333). In samples combined from the coronal sulcus, glans penis, shaft, and scrotum, we evaluated factors associated with any, oncogenic, and nononcogenic HPV infections. In multivariable analyses, detection of any HPV infection was significantly associated with reported race of Asian/Pacific Islander, lifetime and recent number of sexual partners, and having sex in the past 3 months. Oncogenic HPV detection was independently associated with lifetime and recent number of sexual partners, and having sex in the past 3 months. NonOncogenic HPV infection was independently associated with lifetime number of sexual partners. Circumcision, assessed by clinical examination, was associated with reduced risk of HPV detection across all categories of HPV evaluated. HPV detection in men in the current study was strongly related to sexual behavior and circumcision status. Interventions such as circumcision may provide a low-cost method to reduce HPV infection.

    2016-01-01

    Background Experience of domestic violence has negative mental health consequences for women. The association of cumulative and specific forms of domestic violence, particularly emotional violence and controlling behavior, with common mental disorders and stress has rarely been studied in pregnant women. The aim of this study is to evaluate associations of specific and multiple forms of lifetime domestic violence and controlling behavior with distress and cortisol level during pregnancy in rural Bangladeshi women. Methods and findings In this observational sub-study of larger MINIMat trial, 3504 pregnant women were interviewed using a shortened Conflict Tactic Scale about their lifetime experience of domestic violence including physical, sexual, emotional domestic violence and controlling behavior. Women’s levels of emotional distress were assessed using the self-reported questionnaire (SRQ-20) developed by WHO, and levels of morning salivary cortisol were measured in a subsample (n = 1300) of women during week 28–32 of pregnancy. Regression analyses were used to estimate the associations of lifetime physical, sexual, emotional domestic violence and controlling behavior with levels of distress and cortisol during pregnancy. The prevalence of lifetime domestic violence was 57% and emotional distress was 35% in these pregnant women. All forms of domestic violence were associated with higher levels of emotional distress. Women who experienced either emotional violence or controlling behavior had the highest levels of emotional distress. There was a dose-response relationship between cumulative number of the different forms of domestic violence and women’s levels of emotional distress. There was no association between women’s experience of domestic violence and level of morning salivary cortisol. Conclusion Including emotional violence and controlling behavior as major types of violence in future research and health interventions is warranted. Furthermore, the

    Recent research has documented large and robust sex differences in the category specificity of self-reported sexual attraction and viewing times to men and women, with men showing more polarized responses to the two sexes than women. However, this research has been limited by the use of small and restricted samples. To address this, the current study assessed a representative sample of more than 2800 U.S. adults on demographic and attitudinal variables and on two measures of category specificity: one based on self-reported sexual attraction and the other based on viewing times to male and female swimsuit models. Key findings were replicated. On average, men were considerably more category specific in self-reported sexual attraction and viewing times than women, and this was true for both heterosexual and homosexual participants. Self-identified bisexual and asexual participants tended to be lower on category specificity than other groups. Although demographic and attitudinal factors such as age, ethnicity, state and region of residence, social class, political liberalism-conservatism, and religiousness were sometimes weakly related to category specificity, sex differences in category specificity remained robust despite demographic and attitudinal variation.

    A sexual self-schema is a cognitive generalization about sexual aspects of the self. In the current study, we examined how an individual's sexual self-schema influenced the processing of self and partner related sexual information. Specifically, we investigated how sexual self-schemas related to own and partner sexual satisfaction and how they influenced perceptions of partner sexual satisfaction. Participants were 117 heterosexual couples in committed, long-term relationships. Both partners completed measures assessing their sexual self-schemas, their own sexual satisfaction, and perceptions of partner sexual satisfaction. Consistent with our predictions, own sexual schema was associated with own sexual satisfaction. For men, more positive sexual self-schemas were associated with greater sexual satisfaction, and for women, more negative sexual self-schemas were associated with lower sexual satisfaction. For both men and women, there was no significant association between own sexual self-schema and partner sexual satisfaction. Sexual self-schemas directly and indirectly influenced an individual's perception of the partner's sexual satisfaction, such that men and women with more positive sexual self-schemas rated their partners as more sexually satisfied, after controlling for the partner's self-reported level of sexual satisfaction. Our findings demonstrated that sexual self-schemas are relevant to own sexual satisfaction as well as the processing of interpersonally relevant sexual information, specifically one's perceptions of partner sexual satisfaction.

    Since 2004, there has been increased effort to reduce military sexual trauma (MST) in the U.S. military. Although MST covers a range of inappropriate behaviors, the majority of research, treatment, and outreach are focused on sexual assault and the experiences of individuals serving in Afghanistan and Iraq. During a study on veterans' involvement in a national peace organization, participants were asked about their military experiences. Veterans served from World War II to current conflicts in Iraq and Afghanistan. Emerging out of the responses were descriptions of women's experiences with MST, barriers to reporting incidents of sexual misconduct and sexual assault, and the challenges they faced when seeking care. Data were gathered using anonymous questionnaires and semi-structured interviews. Out of 52 female veterans, the majority (90%) was subjected to at least one form of MST, and 15% (8) attempted to report the incident(s). Over half of the assailants were of a higher rank than the survivors. The majority of veterans remained silent due to lack of options to report, the status of perpetrators, and fear of retaliation. These data provide a glimpse into the challenges many women veterans faced when seeking assistance reporting incidents or obtaining health care for their MST.

    Full Text Available In sub-Saharan Africa the population prevalence of men who have sex with men (MSM is unknown, as is the population prevalence of male-on-male sexual violence, and whether male-on-male sexual violence may relate to HIV risk. This paper describes lifetime prevalence of consensual male-male sexual behavior and male-on-male sexual violence (victimization and perpetration in two South African provinces, socio-demographic factors associated with these experiences, and associations with HIV serostatus.In a cross-sectional study conducted in 2008, men aged 18-49 y from randomly selected households in the Eastern Cape and KwaZulu-Natal provinces provided anonymous survey data and dried blood spots for HIV serostatus assessment. Interviews were completed in 1,737 of 2,298 (75.6% of enumerated and eligible households. From these households, 1,705 men (97.1% provided data on lifetime history of same-sex experiences, and 1,220 (70.2% also provided dried blood spots for HIV testing. 5.4% (n = 92 of participants reported a lifetime history of any consensual sexual activity with another man; 9.6% (n = 164 reported any sexual victimization by a man, and 3.0% (n = 51 reported perpetrating sexual violence against another man. 85.0% (n = 79 of men with a history of consensual sex with men reported having a current female partner, and 27.7% (n = 26 reported having a current male partner. Of the latter, 80.6% (n = 21/26 also reported having a female partner. Men reporting a history of consensual male-male sexual behavior are more likely to have been a victim of male-on-male sexual violence (adjusted odds ratio [aOR] = 7.24; 95% CI 4.26-12.3, and to have perpetrated sexual violence against another man (aOR = 3.10; 95% CI 1.22-7.90.

    2015-01-01

    Homeless youth commonly report engaging in sexual risk behaviors. These vulnerable young people also frequently report being sexually victimized. This systematic review collates, summarizes, and appraises published studies of youth investigating relationships between homelessness, perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior. A systematic search of seventeen psychology, health, and social science electronic databases was conducted. Search terms included "homeless*," "youth," "offend*," "victimization," "crime," "rape," "victim*," and "sex crimes." Thirty-eight studies were identified that met the inclusion criteria. Findings showed homeless youth commonly report being raped and sexually assaulted, fear being sexually victimized, and engage in street prostitution and survival sex. Rates of victimization and sexual risk behavior were generally higher for females. Given the paucity of longitudinal studies and limitations of current studies, it is unclear whether homelessness is prospectively associated with sexual victimization or engagement in sexual risk behavior, and whether such associations vary cross nationally and as a function of time and place. Future prospective research examining the influence of the situational context of homelessness is necessary to develop a better understanding of how homelessness influences the perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior among homeless youth.

    The recent observation of {sup 44}Ti radioactivity in the supernova remnant Cassiopeia A with the Compton Gamma Ray Observatory allows the determination of the absolute amount of {sup 44}Ti. This provides a test for current supernova models. The main uncertainty is the lifetime of {sup 44}Ti. We report a new measurement of the lifetime of {sup 44}Ti applying a novel technique. A mixed radioactive beam containing {sup 44}Ti as well as {sup 22}Na was implanted and the resulting {gamma}-activity was measured. This allowed the determination of the lifetime of {sup 44}Ti relative to the lifetime of {sup 22}Na, {tau} = (87.0 {+-} 1.9) y. With this lifetime, the {sup 44}Ti abundance agrees with theoretical predictions within the remaining observational uncertainties. (orig.)

    Lifetime contaminant and hormonal profiles have been reconstructed for an individual male blue whale (Balaenoptera musculus, Linnaeus 1758) using the earplug as a natural aging matrix that is also capable of archiving and preserving lipophilic compounds. These unprecedented lifetime profiles (i.e., birth to death) were reconstructed with a 6-mo resolution for a wide range of analytes including cortisol (stress hormone), testosterone (developmental hormone), organic contaminants (e.g., pesticides and flame retardants), and mercury. Cortisol lifetime profiles revealed a doubling of cortisol levels over baseline. Testosterone profiles suggest this male blue whale reached sexual maturity at approximately 10 y of age, which corresponds well with and improves on previous estimates. Early periods of the reconstructed contaminant profiles for pesticides (such as dichlorodiphenyltrichloroethanes and chlordanes), polychlorinated biphenyls, and polybrominated diphenyl ethers demonstrate significant maternal transfer occurred at 0-12 mo. The total lifetime organic contaminant burden measured between the earplug (sum of contaminants in laminae layers) and blubber samples from the same organism were similar. Total mercury profiles revealed reduced maternal transfer and two distinct pulse events compared with organic contaminants. The use of a whale earplug to reconstruct lifetime chemical profiles will allow for a more comprehensive examination of stress, development, and contaminant exposure, as well as improve the assessment of contaminant use/emission, environmental noise, ship traffic, and climate change on these important marine sentinels.

    The interest in fluorescence lifetime imaging microscopy (FLIM) is increasing, as commercial FLIM modules become available for confocal and multi-photon microscopy. In biological FLIM applications, low fluorescence signals from samples can be a challenge, and this causes poor precision in lifetime. In this study, for the first time, we applied wavelet-based denoising methods in time-domain FLIM, and compared them with our previously developed total variation (TV) denoising methods. They were first tested using artificial FLIM images. We then applied them to lowlight live-cell images. The results demonstrated that our TV methods could improve lifetime precision multi-fold in FLIM images and preserve the overall lifetime and pre-exponential term values when improving local lifetime fitting, while wavelet-based methods were faster. The results here can enhance the precision of FLIM, especially for low-light and / or fast video-rate imaging, to improve current and rapidly emerging new applications of FLIM such as live-cell, in vivo whole-animal, or endoscopic imaging.

    2014-10-01

    In Ethiopia, young people with disabilities (YPWD) are often marginalized and not recognized as being sexual, and only little is known about their sexual reproductive health (SRH) status. We therefore aimed to assess the SRH status and associated factors among 426 YPWD in Addis Ababa, Ethiopia. A cross-sectional survey was conducted in 2012. Data were collected by trained interviewers using a structured questionnaire. Fifty-two percent of YPWD ever had sexual intercourse. Seventy-five percent started sex between 15 and 19 years. Only 35% had used contraceptive during their first sexual encounter. Fifty-nine percent of the sexually experienced YPWD had multiple lifetime sexual partners; 19%, a casual sexual partner; and 21%, a commercial sexual partner. Only 48% consistently used condoms with their casual or commercial sexual partners. Twenty-four percent of the sexually experienced YPWD had a history of sexually transmitted infections. Our findings indicate that YPWD in Ethiopia are sexually active, but also highly involved in risky sexual practices. There is a need for in-depth research to better understand the determinants of risky sexual behavior and to propose preventive approaches.

  12. Dysregulated sexuality and high sexual desire: distinct constructs?

    Winters, Jason; Christoff, Kalina; Gorzalka, Boris B

    2010-10-01

    The literature on dysregulated sexuality, whether theoretical, clinical or empirical, has failed to differentiate the construct from high sexual desire. In this study, we tested three hypotheses which addressed this issue. A sample of 6458 men and 7938 women, some of whom had sought treatment for sexual compulsivity, addiction or impulsivity, completed an online survey comprised of various sexuality measures. Men and women who reported having sought treatment scored significantly higher on measures of dysregulated sexuality and sexual desire. For men, women, and those who had sought treatment, dysregulated sexuality was associated with increased sexual desire. Confirmatory factor analysis supported a one-factor model, indicating that, in both male and female participants, dysregulated sexuality and sexual desire variables loaded onto a single underlying factor. The results of this study suggest that dysregulated sexuality, as currently conceptualized, labelled, and measured, may simply be a marker of high sexual desire and the distress associated with managing a high degree of sexual thoughts, feelings, and needs.

    Frailty, a phenotype reported among 9.9% of individuals 65 years old and older (9.6% of women; 5.2% of men), has not been assessed among adult childhood cancer survivors (CCS). We estimated the prevalence of frailty and examined associations with morbidity and mortality. Participants included 1,922 CCS at least 10 years from original cancer diagnosis (men, 50.3%; mean age, 33.6 ± 8.1 years) and a comparison population of 341 participants without cancer histories. Prefrailty and frailty were defined as two and ≥ three of the following conditions: low muscle mass, self-reported exhaustion, low energy expenditure, slow walking speed, and weakness. Morbidity was defined as grade 3 to 4 chronic conditions (Common Terminology Criteria for Adverse Events version 4.0). Fisher's exact tests were used to compare, by frailty status, percentages of those with morbidity. In a subset of 162 CCS who returned for a second visit, Poisson regression was used to evaluate associations between frailty and new onset morbidity. Cox proportional hazards regression was used to evaluate associations between frailty and death. The prevalence of prefrailty and frailty were 31.5% and 13.1% among women and 12.9% and 2.7% among men, respectively, with prevalence increasing with age. Frail CCS were more likely than nonfrail survivors to have a chronic condition (82.1% v 73.8%). In models adjusted for existing chronic conditions, baseline frailty was associated with risk of death (hazard ratio, 2.6; 95% CI, 1.2 to 6.2) and chronic condition onset (relative risk, 2.2; 95% CI, 1.2 to 4.2). The prevalence of frailty among young adult CCS is similar to that among adults 65 years old and older, suggesting accelerated aging.

    Full Text Available Abstract Background Sexual activities are increasingly changing from the cultural point of view what they used to be. Knowledge of these practices among adolescents may be a basis to create awareness among adolescents on practices that involve risks. This study aims to assess sexual practices among unmarried adolescents in Tanzania. Methods A cross-sectional survey was conducted among in-school and out-of-school but unmarried adolescents aged 10 to 19 in five locations in Tanzania. A questionnaire was used to collect information and to characterize sexual practices among these adolescents. Results About 32% of adolescents reported being sexually active; a higher proportion being males than females. The only inquired and reported sexual practices include vaginal sex, masturbation, oral and anal sex. About 15% of sexually active adolescents reported having multiple sexual partners. Significantly more males reported having multiple partners than females. Nearly 42% of sexually active adolescents reported having used a condom during most recent sexual act. Females reported older partners at first sexual act. Conclusion Adolescents experience several sexual practices that include penetrative and non-penetrative. More males reported being sexually active than females. Despite adolescents reporting having multiple sexual partners, reported condom use during the most recent sexual act was low. We advocate for a more enhanced approach of reproductive health education that includes safer sex to adolescents without forgetting those in-schools.

    Full Text Available O objetivo deste artigo é discutir o processo de revelação e notificação de situações de abuso sexual envolvendo crianças e adolescentes, a partir da análise de publicações relacionadas a essa temática. Os estudos indicam que a revelação e a notificação do abuso sexual são momentos difíceis para a vítima e para seus familiares porque geralmente envolvem alguém próximo à criança e apresentam reflexos no sistema familiar, como rompimento de vínculo, culpabilização e perda de suporte financeiro. Vários fatores que podem facilitar ou inibir a revelação e notificação do abuso são discutidos, como, por exemplo, a reação materna. Destaca-se a importância de um trabalho integrado no atendimento às vítimas, no encaminhamento das questões judiciais e no fortalecimento da rede de apoio às famílias.The aim of this article is to discuss the process of disclosure and reporting of cases of sexual abuse involving children and adolescents, based on the analysis of publications related to that topic. Studies suggest that the disclosure and reporting of sexual abuse is a difficult moment for the victims and their families because it usually involves someone close to the child. It provokes changes in the family system, such as disruption of ties, guilt and loss in financial support. Several factors that may facilitate or inhibit the disclosure and reporting of sexual abuse are discussed such as the mother's reaction. It is highlighted the importance of an integrated work in the service that deals with these situations, involving the victims care, in the forwarding of the processes and in the strengthening of the supporting network for families.

    We report on single Barium ions confined in a near-infrared optical dipole trap for up to three seconds in absence of any radio-frequency fields. Additionally, the lifetime in a visible optical dipole trap is increased by two orders of magnitude as compared to the state-of-the-art using an efficient repumping method. We characterize the state-dependent potentials and measure an upper bound for the heating rate in the near-infrared trap. These findings are beneficial for entering the regime of ultracold interaction in atom-ion ensembles exploiting bichromatic optical dipole traps. Long lifetimes and low scattering rates are essential to reach long coherence times for quantum simulations in optical lattices employing many ions, or ions and atoms.

    Highlighting the relationship between sexual disorders and crime, reviewing and summarizing the articles published throughout 2011 which add to the current knowledge on this subject. Studies on specific populations confirm the association between sexual disorders and crime, particularly between paraphilias and sexual crimes regarding male offenders. Female offenders are less likely to be diagnosed with a sexual disorder. Some case reports focus on unusual paraphilias and lead us to question the vast possibilities of paraphilic contents and sexual arousal patterns. The variations of paraphilic-associated sexual arousal patterns, unconventional sex behaviors or paraphilic disorders are constantly changing. In this sense, the American Psychiatric Association's DSM-5 current proposals for a sexual dysfunction diagnostic category are under intense discussion because of their important clinical and forensic consequences. Sexual violence is a theme not well understood yet. Because of its nature, researching it can raise many ethical problems. There is no possibility of clinical trials and of case-control studies. Even cohort studies may be problematic in themselves. So, most of the research involves biased samples or case reports, or is merely theoretical. Further research is needed to improve our understanding of the subject, so that preventive and rehabilitative measures can be taken.

  20. Modeling of US Human Papillomavirus (HPV) Seroprevalence by Age and Sexual Behavior Indicates an Increasing Trend of HPV Infection Following the Sexual Revolution.

    2017-09-01

    The United States has experienced an increase in the incidence of human papillomavirus (HPV)-related cancers that are not screen-detectable. It has been hypothesized, but not directly demonstrated, that this is due to increasing HPV prevalence in the unvaccinated population. Female self-reported numbers of lifetime sex partners and HPV serology from the National Health and Nutrition Examination Survey (NHANES) were used to develop mathematical models of sexual partner acquisition and antibody dynamics. Modeled trends in sexual behaviors were compared to incidence data for cervical adenocarcinoma, oropharyngeal cancer, and anal cancer. The age-specific HPV seroprevalence data were best explained by a partner acquisition model that explicitly accounted for cohort-dependent changes in sexual behavior. Estimates of the mean time to loss of natural antibodies varied by model, ranging from 49 to 145 years. Inferred trends in sexual behavior over the past decades paralleled the increasing incidence of HPV-related cancers in the United States. The findings suggest that lower HPV seroprevalence in older US women primarily reflects cohort-specific differences in sexual behaviors, and is only marginally attributable to immune waning with age. Our results emphasize the importance of continuing surveillance of sexual behaviors, alongside vaccine status, to predict future disease burden.

    Sexual violence, stalking, and intimate partner violence are public health problems known to have a negative impact on millions of persons in the United States each year, not only by way of immediate harm but also through negative long-term health impacts. Before implementation of the National Intimate Partner and Sexual Violence Survey (NISVS) in 2010, the most recent detailed national data on the public health burden from these forms of violence were obtained from the National Violence against Women Survey conducted during 1995-1996. This report examines sexual violence, stalking, and intimate partner violence victimization using data from 2011. The report describes the overall prevalence of sexual violence, stalking, and intimate partner violence victimization; racial/ethnic variation in prevalence; how types of perpetrators vary by violence type; and the age at which victimization typically begins. For intimate partner violence, the report also examines a range of negative impacts experienced as a result of victimization, including the need for services. January-December, 2011. NISVS is a national random-digit-dial telephone survey of the noninstitutionalized English- and Spanish-speaking U.S. population aged ≥18 years. NISVS gathers data on experiences of sexual violence, stalking, and intimate partner violence among adult women and men in the United States by using a dual-frame sampling strategy that includes both landline and cellular telephones. The survey was conducted in 50 states and the District of Columbia; in 2011, the second year of NISVS data collection, 12,727 interviews were completed, and 1,428 interviews were partially completed. In the United States, an estimated 19.3% of women and 1.7% of men have been raped during their lifetimes; an estimated 1.6% of women reported that they were raped in the 12 months preceding the survey. The case count for men reporting rape in the preceding 12 months was too small to produce a statistically reliable

    When first presented, Freud´s theory of infantile sexuality was a scandal. Not only was the claim that the small child sucking at the mother´s breast experiences a kind of pleasure that Freud without hesitation named sexual, the theory also turned the common understanding of human sexuality up...... vision of the sexual. Following a historic outline, we examine the theories that inspired by Laplanche, once more discuss infantile sexuality, and argue that infantile sexuality is clarified by combining the concept of the drive with what in effect is an inter-subjective point of view....

    Local molecular and physiological processes can be imaged in vivo through perturbations in the fluorescence lifetime (FLT) of optical imaging agents. In addition to providing functional information, FLT methods can quantify specific molecular events and multiplex diagnostic and prognostic information. We have developed a fluorescence lifetime diffuse optical tomography (DOT) system for in vivo preclinical imaging. Data is captured using a time-resolved intensified charge coupled device (ICCD) system to measure fluorescence excitation and emission in the time domain. Data is then converted to the frequency domain, and we simultaneously reconstruct images of yield and lifetime using an extension to the normalized Born approach. By using differential phase measurements, we demonstrate DOT imaging of short lifetimes (from 350 ps) with high precision (+/-5 ps). Furthermore, this system retains the efficiency, speed, and flexibility of transmission geometry DOT. We demonstrate feasibility of FLT-DOT through a progressive series of experiments. Lifetime range and repeatability are first measured in phantoms. Imaging of subcutaneous implants then verifies the FLT-DOT approach in vivo in the presence of inhomogeneous optical properties. Use in a common research scenario is ultimately demonstrated by imaging accumulation of a targeted near-infrared (NIR) fluorescent-labeled peptide probe (cypate-RGD) in a mouse with a subcutaneous tumor.

    We present experimental atomic lifetimes for 12 levels in Sb I, out of which seven are reported for the first time. The levels belong to the 5p$^2$($^3$P)6s $^{2}$P, $^{4}$P and 5p$^2$($^3$P)5d $^{4}$P, $^{4}$F and $^{2}$F terms. The lifetimes were measured using time-resolved laser-induced fluorescence. In addition, we report new calculations of transition probabilities in Sb I using a Multiconfigurational Dirac-Hartree-Fock method. The physical model being tested through comparisons between theoretical and experimental lifetimes for 5d and 6s levels. The lifetimes of the 5d $^4$F$_{3/2, 5/2, 7/2}$ levels (19.5, 7.8 and 54 ns, respectively) depend strongly on the $J$-value. This is explained by different degrees of level mixing for the different levels in the $^4$F term.

    The purpose of the present study was to examine the relationship between college women's sexual victimization experiences, health risk behaviors, and sexual functioning. A sample of 309 college women at a mid-sized Midwestern university completed measures assessing sexual victimization, sexual risk taking, substance use behaviors, sexual desire, sexual functioning, prior sexual experiences, and social desirability. Severity of sexual victimization was measured using a multi-item, behaviorally specific, gender-neutral measure, which was divided into four categories based on severity (none, sexual contact, sexual coercion, rape). Within the sample, 72.8% (n = 225) of women reported at least one experience of sexual victimization since age 16. Results from MANCOVAs and a multinomial logistic regression, controlling for social desirability and prior sexual experience, revealed that sexual victimization among female students was related to increased drug use, problematic drinking behaviors, sexual risk taking, sexual dysfunction, and dyadic sexual desire. In addition, findings indicated that women exposed to more severe forms of sexual victimization (i.e., rape) were most likely to report these risk-taking behaviors and sexual functioning issues. Implications for sexual assault risk reduction programming and treatment are discussed.

    There have not been any population-based surveys in Germany to date on the frequency of various types of sexual behavior. The topic is of interdisciplinary interest, particularly with respect to the prevention and treatment of sexually transmitted infections. Within the context of a survey that dealt with multiple topics, information was obtained from 2524 persons about their sexual orientation, sexual practices, sexual contacts outside relationships, and contraception. Most of the participating women (82%) and men (86%) described themselves as heterosexual. Most respondents (88%) said they had engaged in vaginal intercourse at least once, and approximately half said they had engaged in oral intercourse at least once (either actively or passively). 4% of the men and 17% of the women said they had been the receptive partner in anal intercourse at least once. 5% of the respondents said they had had unprotected sexual intercourse outside their primary partnership on a single occasion, and 8% said they had done so more than once; only 2% of these persons said they always used a condom during sexual intercourse with their primary partner. Among persons reporting unprotected intercourse outside their primary partnership, 25% said they had undergone a medical examination afterward because of concern about a possible sexually transmitted infection. Among some groups of persons, routine sexual-medicine examinations may help contain the spread of sexually transmitted infections. One component of such examinations should be sensitive questioning about the types of sexual behavior that are associated with a high risk of infection. Information should be provided about the potential modes of transmission, including unprotected vaginal, oral, and anal intercourse outside the primary partnership.

Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic fre...

    Latent profile analysis (LPA) was used to classify 394 adolescents undergoing substance use treatment, based on past year psychiatric symptoms. Relations between profile membership and (a) self-reported childhood maltreatment experiences and (b) current sexual risk behavior were examined. LPA generated three psychiatric symptom profiles: Low-, High- Alcohol-, and High- Internalizing Symptoms profiles. Analyses identified significant associations between profile membership and childhood sexual abuse and emotional neglect ratings, as well as co-occurring sex with substance use and unprotected intercourse. Profiles with elevated psychiatric symptom scores (e.g., internalizing problems, alcohol abuse and dependence symptoms) and more severe maltreatment histories reported higher scores for behavioral risk factors for HIV/STI exposure. Heterogeneity in psychiatric symptom patterns among youth receiving substance use treatment services, and prior histories of childhood maltreatment, have significant implications for the design and delivery of HIV/STI prevention programs to this population.

    Affinity is a computerized assessment tool that combines viewing time and self-report measures of sexual interest. The present study was designed to assess the diagnostic properties of Affinity with respect to sexual interest in prepubescent children. Reliability of both self-report and viewing time components was estimated to be high. The group profile of a sample of pedophilic adult male child molesters (n = 42, all of whom admitted their offenses) differed from the group profiles of male community controls (n = 95) and male nonsexual offenders (n = 27), respectively. More specifically, both ratings and viewing times for images showing small children or prejuvenile children were significantly higher within the child molester sample than in either of the other two groups, attesting to the validity of the measures. Overall classification accuracy, however, was mediocre: A multivariate classification routine yielded 50% sensitivity for child molester status at the cost of 13% false positives. The implications for forensic use of Affinity are discussed.

    Women suffering from eating disorders, present considerable retardation and difficulties in their psychosexual development during adolescence. This leads to primary or secondary insufficiencies in their adult sexual life. The cause of these difficulties seems to be a series of biological, family and psychosocial factors. The majority of the research findings indicate that eating disorders have a negative impact on the patient's sexual function. The factors related to eating disorders symptomatology that influence sexuality are various and differ among each eating disorder diagnostic categories. Considering anorexia nervosa, it has been reported that women have negative attitudes to sexual issues and their body. Their sexual motivation increases when they engage in psychotherapy and their body weight is gradually restored. Starvation and its consequences on the human physiology and especially on the brain function seem to be the main factor that leads to reduced sexual desire and scarce sexual activity. Moreover, personality traits that are common in patients suffering from anorexia nervosa such as compulsivity and rigidity are also related with difficulties initiating and retaining romantic and sexual relationships. Usually patients suffering from anorexia nervosa report impaired sexual behavior and lack of interest to engage in a sexual relationship. Considering Bulimia Nervosa, impulsivity and difficulties in emotion regulation that are common features of the individuals that suffer from bulimia nervosa are also related to impulsive and sometimes self-harming sexual behaviors. Moreover women sufferers often report repulsion, anger and shame towards their body and weight, mainly due to the distorted perception that they are fat and ugly. It is interesting that a number of research findings indicate that although patients suffering from bulimia nervosa are more sexually active and have more sexual experiences than patients suffering from anorexia nervosa, both

    Epidemiologic data on sexual behavior in psoriasis patients are lacking. We aim to examine and compare the sexual behaviors between men with and without psoriasis in the United States. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2006 and 2009 to 2010. Responses from male participants to the dermatology and sexual behavior questionnaires of the NHANES were collated and analyzed. Outcome measures included sexual orientation, age of first sexual encounter, number of oral and non-oral sexual partners, and frequency of unprotected sex. Among 6,444 U.S. men that responded to the psoriasis question, 170 (2.6%) reported a physician-given diagnosis of psoriasis. Heterosexual men accounted for 95.5% and nonheterosexual men 4.5% of the overall study population. On multivariate analysis, psoriasis was not associated with differences in sexual orientation (odds ratio 1.78, 95% confidence interval [CI] 0.75-4.15). Heterosexual men with psoriasis experienced first sexual encounter at an earlier age than those without psoriasis (weighted difference -0.9 years, P = 0.002). Heterosexual men with psoriasis had significantly fewer female oral sexual partners compared with heterosexual men without psoriasis on multivariate analysis (lifetime partner number: rate ratio [RR] 0.65, 95% CI 0.45-0.95; past-year partner number: RR 0.64, 95% CI 0.42-0.97). No significant differences existed between heterosexual men with and without psoriasis regarding frequency of unprotected sex (RR 0.96, 95% CI 0.85-1.09). Among nonheterosexual men with and without psoriasis, no significant differences existed in age first had sex, number of sexual partners, or frequency of unprotected sex. Heterosexual men with psoriasis have significantly fewer lifetime female oral sexual partners compared with those without psoriasis. Dermatologists and other healthcare providers need to examine the genital region routinely and initiate appropriate therapy to improve

    The study of sexual satisfaction in Spain is scarce and has proceeded atheoretically. This study aimed at examining sexual satisfaction in 197 Spanish heterosexual couples based on the Interpersonal Exchange Model of Sexual Satisfaction. Men and women reported equal satisfaction. Men's sexual satisfaction was predicted by their own relationship satisfaction, balance of sexual rewards and costs, and comparison level of sexual rewards and costs. Women's sexual satisfaction was predicted by their own relationship satisfaction, balance of sexual rewards and costs, comparison level of sexual rewards and costs, equality of sexual costs, and their partner's balance of sexual rewards and costs. These results provide with a better understanding of the mechanisms that explain sexual satisfaction in Spanish couples. Implications for research and therapy are discussed.

    In a case-control study of hormonal contraceptives and invasive cervical cancer, an unexpected finding was a substantial decline in the prevalence of high-risk human papillomavirus (HPV) infection according to the lifetime number of Pap smears received. Here we assess the risk of 3 sexually transmitted viral infections -- herpes simplex virus 2 (HSV2), HPV, and human immunodeficiency virus (HIV) 1 and 2 -- in relation to the lifetime receipt of Pap smears. Stored sera taken from 1540 controls were tested for HSV2 and HIV; cervical scrapings were tested for HPV. Confounder-adjusted odds ratios for the lifetime receipt of Pap smears were estimated, relative to never having had a Papanicolau test. For ever-receipt of a Papanicolau test, the odds ratios for HSV2 and HPV were 0.7 (95% confidence interval = 0.5-0.9) and 0.5 (0.3-0.7), respectively, and there were dose-response trends according to the lifetime number of Pap smears received (test for trend P = 0.02 and 0.04, respectively). For HSV2 the odds ratios according to last receipt declined from 0.8 for 10 or more years previously to 0.4 for <1 year previously (trend P = 0.002). For HPV the ORs were 0.4 (0.3-0.7) for last receipt 5-9 years previously and 0.5 (0.4-0.8) for less than 5 years previously; for HIV the odds ratio for last receipt less than 5 years previously was 0.4 (0.3-0.9). For HSV2 and HIV the crude odds ratio estimates were systematically lower than the adjusted estimates, and residual confounding cannot be ruled out. In particular, the true number of sexual partners may have been under-reported, and there was no information on the sexual activity of the male partners, or on other health behaviors of the women or their partners. We hypothesize that Pap smears may provoke a short-term immune response against sexually transmitted viral infections.

  6. Social networking smartphone applications and sexual health outcomes among men who have sex with men.

    Full Text Available Several smartphone applications (apps designed to help men who have sex with men (MSM find casual sexual partners have appeared on the market recently. Apps of this nature have the potential to impact sexual health and behavior by providing constant access to a large supply of available partners. In this study, the sexual health history, behavior, and personality of MSM who use these apps was compared to MSM who meet partners in other ways. A sample of 110 adult MSM was recruited online to complete a cross-sectional survey. All participants were either single or involved in a non-exclusive romantic relationship. There were no statistically significant differences between app users and non-users in frequency of insertive or receptive anal sex without a condom. However, app users reported significantly more sexual partners and had a higher prevalence of ever being diagnosed with an STI than did non-users. App users did not differ from non-users on any demographic or personality variables (including erotophilia, sensation seeking, and self-control; however, when adjusting lifetime total sex partners for those met specifically through apps, app users still had significantly more partners. This pattern of results suggests that app users may be more sexually active in general. More work is needed to fully understand the association between this emerging technology and potential sexual health risks.

  7. Prevalence of Pelvic Inflammatory Disease in Sexually Experienced Women of Reproductive Age - United States, 2013-2014.

    Pelvic inflammatory disease (PID) is a clinical syndrome of the female reproductive tract characterized by inflammation of the endometrium, fallopian tubes, or peritoneum (1). PID occurs when microorganisms ascend from the vagina or cervix to the fallopian tubes and other upper genital tract structures (1). PID can result from untreated bacterial infections, including chlamydia and gonorrhea, and can lead to infertility, ectopic pregnancy, and chronic pelvic pain (1). Because there is no single diagnostic test for PID, clinicians rely on nonspecific signs and symptoms for diagnosis. The purpose of these analyses was to assess the burden of self-reported PID in a nationally representative sample using data from the National Health and Nutrition Examination Survey (NHANES) 2013-2014 cycle. Starting in 2013, NHANES female participants aged 18-44 years were asked about a lifetime history of PID diagnosis. Based on these data, the estimated prevalence of self-reported lifetime PID was 4.4% in sexually experienced women of reproductive age (18-44 years). The prevalence of self-reported lifetime PID was highest in women at increased risk, such as women reporting a previous sexually transmitted infection (STI) diagnosis. Stratified by race/ethnicity and having a previous STI diagnosis, non-Hispanic black (black) and non-Hispanic white (white) women reporting a previous STI diagnosis had nearly equal self-reported lifetime PID prevalence (10.0% versus 10.3%). However, the lifetime prevalence of PID among black women was 2.2 times that among white women if no previous STI was diagnosed (6.0% versus 2.7%). These findings suggest that PID is prevalent and associated with previous STI diagnoses; therefore, it is important for clinicians to screen female patients for chlamydia and gonorrhea to reduce the incidence of PID.

    Full Text Available Abstract Background The 2004 Demographic and Health Survey (DHS in Cameroon revealed a higher prevalence of HIV in richest and most educated people than their poorest and least educated compatriots. It is not certain whether the higher prevalence results partly or wholly from wealthier people adopting more unsafe sexual behaviours, surviving longer due to greater access to treatment and care, or being exposed to unsafe injections or other HIV risk factors. As unsafe sex is currently believed to be the main driver of the HIV epidemic in sub-Saharan Africa, we designed this study to examine the association between wealth and sexual behaviour in Cameroon. Methods We analysed data from 4409 sexually active men aged 15–59 years who participated in the Cameroon DHS using logistic regression models, and have reported odds ratios (OR with confidence intervals (CI. Results When we controlled for the potential confounding effects of marital status, place of residence, religion and age, men in the richest third of the population were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.43, 95% CI 0.32–0.56 and more likely to have had at least two concurrent sex partners in the last 12 months (OR 1.38, 95% CI 1.12–1.19 and more than five lifetime sex partners (OR 1.97, 95% CI 1.60–2.43. However, there was no difference between the richest and poorest men in the purchase of sexual services. Regarding education, men with secondary or higher education were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.24, 95% CI 0.16–0.38 and more likely to have started sexual activity at age 17 years or less (OR 2.73, 95% CI 2.10–3.56 and had more than five lifetime sexual partners (OR 2.59, 95% CI 2.02–3.31. There was no significant association between education and multiple concurrent sexual partnerships in the last 12 months or purchase of sexual services

    A multidimensional measure assessing distinct motivations for and against sex was shown to be reliable, valid, and configurally invariant among incoming first-year college students. Three Motivations Against Sex Questionnaire subscales were developed to measure motivations against sexual behavior (Values, Health, Not Ready) to complement and extend a set of Sexual Motivations Scale-Revised subscales assessing motivations for sexual behavior (Intimacy, Enhancement, Coping). Participants were surveyed the summer prior to college (N = 1,653; 58.4% female). Exploratory factor analysis on a random one quarter of respondents supported the hypothesized factors. Multigroup confirmatory factor analysis demonstrated good overall fit to the data and configural invariance across gender and ethnicity and across lifetime sexual experience. Motivations were associated with lifetime oral and penetrative sexual behaviors. This combined measure may be used for identifying motivations, predicting behaviors, and tailoring motivational interventions for sexual health among adolescents and young adults.

    2014-01-01

    The goal of this study was to characterize the sexuality of sexual-minority (i.e., lesbian, bisexual, queer, unlabeled, questioning) women. Participants were 586 women (87% White) in a same-sex relationship of 1 to 36 years in duration. They completed measures assessing their sexual behavior (frequency of nongenital and genital sexual activities), motivation (sexual desire), and cognitive-affective responses (sexual satisfaction, sexual esteem, sexual anxiety, negative automatic thoughts). On average, the women reported experiencing their sexuality positively across all domains. Regardless of relationship duration, most of the women reported engaging in both genital and nongenital sexual behaviors with their partner once a week or more; few reported that they had not engaged in sexual activity in the previous month. A multiple regression analysis indicated that frequency of genital sexual activity, sexual desire, sexual anxiety, and automatic thoughts contributed uniquely to the prediction of sexual satisfaction over and above the other sexuality variables. The findings are discussed in terms of the idea that lesbians have sex less frequently than other couple types and that sexual frequency declines rapidly in lesbian relationships (i.e., "lesbian bed death") and descriptions of sexual-minority women's sexuality that suggest that genital sexual activity is not important to sexual satisfaction.

    This study examined the relationships between childhood attachment and coercive sexual behavior. One hundred sixty-two male undergraduate students completed self-report measures of childhood maternal attachment, childhood paternal attachment, adult attachment, antisociality, aggression, and coercive sexual behavior. As predicted, insecure childhood attachment, especially insecure paternal attachment, was associated with antisociality, aggression, and coercive sexual behavior. Moreover, childhood attachment independently predicted coercive sexual behavior after antisociality and aggression were statistically controlled. The hypothesis that paternal avoidant attachment would predict coercive sexual behavior independently of its relationship with aggression and antisociality was also supported. Posthoc analysis indicated that maternal anxious attachment was associated with antisociality and that paternal avoidant attachment was associated with both antisociality and coercive sexual behavior. These results are consistent with criminological and psychological research linking adverse early family experiences with offending and lend support to an attachment-theoretical framework for understanding offending behavior in general and sexual offending behavior in particular.

    Estimating the size of key risk groups susceptible to HIV/sexually transmitted diseases (STI) is necessary for establishment of interventions and budget allocation. This study aimed to identify various dimensions of sexual orientation and practices in Israel, and correlate the findings with sexual risk behavior (SRB). It used a random representative sample of the Jewish population aged 18-44 years who completed online questionnaires regarding their self-identified sexual orientation, attraction and practices, and SRB. Concordant heterosexuals were those who self-reported heterosexual identity, were attracted and had sex only with the opposite gender. National estimates regarding prevalence of gay, lesbian, and bisexual men and women were based on the civil census. The sample included 997 men and 1005 women, of whom 11.3 and 15.2 % were attracted to the same-gender, 10.2 and 8.7 % reported lifetime same-gender encounters, while 8.2 and 4.8 % self-identified as gay or bisexual men and lesbian or bisexual women, respectively. The estimated population of self-identified Jewish gay or bisexual men and lesbian or bisexual women aged 18-44 in Israel was 94,176, and 57,671, respectively. SRB was more common among self-identified gays or bisexual men and among discordant heterosexual men and women. Those who reported same-gender sexual practices reported greater SRB than those who only had opposite-gender encounters. Interestingly, SRB among discordant heterosexuals was associated with same-sex behavior rather than attraction. Health practitioners should increase their awareness of sexual diversity among their clientele, and should recognize that risk for HIV/STI may exist among self-identified heterosexuals, who may not disclose their actual sexual attraction or practices.

    The case of a 30 year-old Thai female found dead on the floor at the base of a small monument on Rajadumnern Road, Bangkok, Thailand with blood stains around the body and a naked bottom. The scene investigation and autopsy findings suggested a sexual assault and multiple sharp force injuries. The approach to the postmortem examination using different laboratory tests is reviewed. The specificity and sensitivity of prostate specific antigen (PSA) in specimens from rape victims is better than acid phosphatase test. The ELISA test for PSA was tested to confirm the PSA test kit. The present report suggests the PSA test kit in addition to conventional sperm smear and acid phosphatase test for sexual assault investigation in Thailand.

    People begin to become aware of their sexual drive and erotic feelings as young adolescents. Such activity often has been overlooked in Taiwan, a traditional society, because sexuality is viewed as a private issue. The purpose of this study was to explore the sexual self-concept and intended sexual behavior of young adolescent girls in Taiwan. Participants included 372 girls, 12 to 14 years old, from junior high schools in Taiwan who completed two questionnaires on sexual experience and sexually related items: the Sexual Self-Concept Inventory, the Parental Approval of Sexual Behavior Scale, and the Friends' Approval of Sexual Behavior Scale, which were combined into one scale, with separate scores. Girls' self-reports showed low (negative) sexual self-concept, high perceived parental disapproval, and somewhat high perceived friends' disapproval of sexual activities. Sexual self-concept is associated with perceived parental and peer approval of sexual activities, and it is associated with sexual experience and intended sexual activities as well. A young adolescent girl who has a high score on the perceived sexual arousability factor of the Sexual Self-Concept Inventory is more likely to report the strongest intention toward sexual behavior. Sexual self-concept may play a key role in girls' intended sexual activities, including engaging in low-level sexual activities (e.g., kissing and breast fondling) that occur before intercourse, even when associated with intercourse intention. The research suggests that addressing sexual self-concept needs to be a priority to prevent young girls from engaging in sexual intercourse.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    If new TeV scale particles are discovered, it will be important to determine their width. There is, however, a problematic region, where the width is too small to be determined directly, and too large to generate a secondary vertex. For a collection of colored, spin polarized particles, hadronization depolarizes the particles prior to their decay. The amount of depolarization can be used to probe the lifetime in the problematic region. In this paper we apply this method to a realistic scenario of a top-like particle that can be produced at the LHC. We study how depolarization affects the angular distributions of the decay products and derive an equation for the distributions that is sensitive to the lifetime.

We study how depolarization affects the angular distributions of the decay products and derive an equation for the distributions that is sensitive to the lifetime.

  20. Collecting Sexual Orientation and Gender Identity Data in Suicide and Other Violent Deaths: A Step Towards Identifying and Addressing LGBT Mortality Disparities

    OpenAIRE

    2015-01-01

    Sexual orientation and gender identity (SO/GI) are not systematically recorded at time of death, limiting identification of mortality disparities in lesbian, gay, bisexual, and transgender (LGBT) people. LGBT populations are thought to have elevated risk of suicide based on high rates of reported lifetime suicide attempts. Lack of data on suicide deaths, however, hinders understanding of the prevalence and patterns of suicide among LGBT populations and development of targeted interventions an...

    The hadron identification in the PANDA experiment at FAIR will be done with DIRC detectors. Because of design and space reasons the sensors of the DIRCs have to be placed inside the strong magnetic field of the solenoid. As the favored photon sensors microchannel-plate photomultipliers (MCP-PMTs) were identified. However, these devices showed serious aging problems until very recently, which manifest themselves by a fast degrading quantum efficiency (QE) of the photo cathode (PC). This is mainly due to feedback ions from the residual gas. In this paper we discuss the recently accomplished huge improvements in the lifetime of MCP-PMTs. With innovative countermeasures applied to the MCP-PMTs in the attempt to reduce the aging effects the manufacturers were able to increase the lifetime of MCP-PMT prototypes by almost two orders of magnitude compared to the former commercially available devices. Our group has studied the aging of MCP-PMTs for more than four years by simultaneously illuminating different types of lifetime-enhanced MCP-PMTs at the same photon rate. Gain, dark count rate, and QE as a function of the wavelength and the PC surface were measured in regular time intervals and studied in dependence of the integrated anode charge. We observe that MCP-PMTs treated with an atomic layer deposition (ALD) technique are by far the best devices available now. A lifetime of up to 10 C/cm2 integrated anode charge was reached with these sensors. This is sufficient for both PANDA DIRCs.

    Full Text Available INTRODUCTION: Sexual transmission of human herpesvirus 8 (HHV8 has been implicated among homosexual men, but the evidence for sexual transmission among heterosexual individuals is controversial. We investigated the role of sexual transmission of HHV8 in a nationally representative sample in Uganda, where HHV8 infection is endemic and transmitted mostly during childhood. MATERIALS AND METHODS: The study population was a subset of participants (n = 2681 from a population-based HIV/AIDS serobehavioral survey of adults aged 15-59 years conducted in 2004/2005. High risk for sexual transmission was assessed by questionnaire and serological testing for HIV and herpes simplex virus 2. Anti-HHV8 antibodies were measured using two enzyme immunoassays targeting synthetic peptides from the K8.1 and orf65 viral genes. The current study was restricted to 2288 sexually active adults. ORs and 95% CIs for HHV8 seropositivity were estimated by fitting logistic regression models with a random intercept using MPLUS and SAS software. RESULTS: The weighted prevalence of HHV8 seropositivity was 56.2%, based on 1302 seropositive individuals, and it increased significantly with age (P(trend<0.0001. In analyses adjusting for age, sex, geography, education, and HIV status, HHV8 seropositivity was positively associated with reporting two versus one marital union (OR:1.52, 95% CI: 1.17-1.97 and each unit increase in the number of children born (OR: 1.04, 95% CI: 1.00-1.08, and was inversely associated with ever having used a condom (OR: 0.64, 95% CI: 0.45-0.89. HHV8 seropositivity was not associated with HIV (P = 0.660 or with herpes simplex virus 2 (P = 0.732 seropositivity. Other sexual variables, including lifetime number of sexual partners or having had at least one sexually transmitted disease, and socioeconomic variables were unrelated to HHV8 seropositivity. CONCLUSION: Our findings are compatible with the conclusion that sexual transmission of HHV8 in

  4. Lifetime Resolved Fluorescence Fluctuation Spectroscopy

    Fluorescence correlation spectroscopy (FCS) has been widely used investigate molecular dynamics and interactions in biological systems. FCS typically resolves the component species of a sample either through differences in diffusion coefficient or molecular brightness. Diffusion based assays currently have a major limitation which requires that the diffusion coefficients of component species in a sample must be substantially different in order to be resolved. This criterion is not met in many important cases, such as when molecules of similar molecular weight bind to each other. This limitation can be overcome, and resolution of FCS measurements enhanced, by combining FCS measurements with measurements of fluorescence lifetimes. By using of global analysis on simultaneously acquired FCS and lifetime data we show that we can dramatically enhance resolution in FCS measurements, and accurately resolve the concentration and diffusion coefficients of multiple sample components even when their diffusion coefficients are identical provided there is a difference in the lifetime of the component species. We show examples of this technique using both simulations and experiments. It is expected that this method will be of significance for binding assays studying molecular interactions.

    Full Text Available Introduction. There is an ample evidence of the impact of severe traumatic events, such as sexual abuse in childhood, on the formation of disorders - especially the non-psychotic ones: sexual, neurotic and personality. So far, an increase of the risk with the accumulation of traumatic factors has been indicated, but less attention has been paid to adverse events such as lack of sexual education, negative attitudes of the caregivers towards sexuality, etc. Aim. Assessment of the risk of such adverse events in childhood and adolescence, concerning the symptoms from the area of sexuality as well as other neurotic disorders areas.Method. The coexistence of the earlier life circumstances and currently present symptoms was examined on the basis of KO„0” Symptom Checklist and Life Inventory, completed prior to treatment in a day hospital for neurotic disordersResults. In the group of 2582 females and 1347 males, there was a significant prevalence of symptoms related to sexuality, as well as of other neurotic symptoms. Patients reported traumatic events of varying frequency (from a relatively rare incest, to much more frequent sense of lack of sex education. Regression analyses showed a significant relationship between the analyzed events and symptoms, for instance, lack of sexual satisfaction in adulthood co-occurred in women with punishing for childhood sexual plays or masturbation. The other analyzed symptoms – ‘non-sexual’, such as panic attacks, were not so clearly related to the burdensome circumstances.Conclusions. The presence of adverse life events concerning sexuality, not necessarily the most serious ones e.g. abuses, but such as inadequate sex education, child punishing for masturbation or sexual plays, unwanted sexual initiation, are associated with a higher occurrence of most of the analyzed symptoms in the sphere of sexuality. Weaker connection for other than sexual neurotic symptoms suggests that the impact of childhood sexual

    Child sexual abuse has the potential to cause distress for the victim across the lifespan. Romantic relationships may be particularly difficult for victims of child sexual abuse. This retrospective study examined differences in adult romantic attachment, sexually compulsive behaviors, and emotion regulation by history of child sexual abuse in a large, nonclinical sample. Those with a history of child sexual abuse reported more attachment anxiety in romantic relationships and engaged in more sexually compulsive behaviors. Overall, males displayed more sexually compulsive behaviors than females regardless of history of sexual abuse. Males with a history of sexual abuse displayed the greatest number of sexually compulsive behaviors. Surprisingly, no differences were observed in emotion regulation or attachment avoidant behaviors by history of child sexual abuse. Future research should seek to replicate current findings and examine emotion regulation difficulties experienced as a result of trauma.

    The prevalence of childhood sexual and physical abuse among persons with severe mental illness (SMI) is disproportionately high. Adults with SMI also engage in high rates of HIV risk behaviors. This study examined the association between childhood abuse and adult victimization, substance abuse, and lifetime HIV sexual risk in a sample of 152 adults with SMI receiving community mental health services. Structured interviews assessed psychiatric, psychosocial, and behavioral risk factors. Seventy percent reported childhood physical and/or sexual abuse, and 32% reported both types of abuse. Participants with childhood abuse were more likely to report adult victimization and greater HIV risk. A structural equation model found that childhood abuse was directly and indirectly associated with HIV risk through drug abuse and adult vicitimization. Integrated treatment approaches that address interpersonal violence and substance abuse may be necessary for HIV risk reduction in this population.

    2011-08-01

    Conventional fluorescence lifetime imaging requires complicated algorithms to extract lifetimes of fluorophores and acquisition of multiple data points at progressively longer delay times to characterize tissues. To address diminishing signal-to-noise ratios at these progressively longer time delays, we report a time-resolved fluorescence imaging method, normalized fluorescence yield imaging that does not require the extraction of lifetimes. The concept is to extract the ``contrast'' instead of the lifetime value of the fluorophores by using simple mathematical algorithms. This process converts differences in decay times directly to different intensities. The technique was verified experimentally using a gated iCCD camera and an ultraviolet light-emitting diode light source. It was shown that this method can distinguish between chemical dyes (Fluorescein and Rhodamine-B) and biomedical samples, such as powders of elastin and collagen. Good contrast was obtained between fluorophores that varied by less than 6% in lifetime. Additionally, it was shown that long gate times up to 16 ns achieve good contrast depending upon the samples to be studied. These results support the feasibility of time-resolved fluorescence imaging without lifetime extraction, which has a potential clinical role in noninvasive real-time imaging.

    Full Text Available In this article, a fluorescence lifetime imaging system for small animals is presented. Data were collected by scanning a region of interest with a measurement head, a linear fiber array with fixed separations between a single source fiber and several detection fibers. The goal was to localize tumors and monitor their progression using specific fluorescent markers. We chose a near-infrared contrast agent, Alexa Fluor 750 (Invitrogen Corp., Carlsbad, CA. Preliminary results show that the fluorescence lifetime for this dye was sensitive to the immediate environment of the fluorophore (in particular, pH, making it a promising candidate for reporting physiologic changes around a fluorophore. To quantify the intrinsic lifetime of deeply embedded fluorophores, we performed phantom experiments to investigate the contribution of photon migration effects on observed lifetime by calculating the fluorescence intensity decay time. A previously proposed theoretical model of migration, based on random walk theory, is also substantiated by new experimental data. The developed experimental system has been used for in vivo mouse imaging with Alexa Fluor 750 contrast agent conjugated to tumor-specific antibodies (trastuzumab [Herceptin]. Three-dimensional mapping of the fluorescence lifetime indicates lower lifetime values in superficial breast cancer tumors in mice.

    This review summarizes the recent progress in the stability and lifetime of organic photovoltaics (OPVs). In particular, recently proposed solutions to failure mechanisms in different layers of the device stack are discussed comprising both structural and chemical modifications. Upscaling is additionally discussed from the perspective of stability presenting the challenges associated with device packaging and edge protection. An important part of device stability studies is the characterization, and this review provides a short overview of the most advanced techniques for stability characterization reported recently. Lifetime testing and determination is another challenge in the field of organic solar cells and the final sections of this review discuss the testing protocols as well as the generic marker for device lifetime and the methodology for comparing all the lifetime landmarks in one common diagram. These tools were used to determine the baselines for OPV lifetime tested under different ageing conditions. Finally, the current status of lifetime for organic solar cells is presented and predictions are made for progress in the near future.

    The longitudinal risk for human immunodeficiency virus (HIV) infection following adolescent substance treatment is not known. Therefore, it is not known if adolescent substance treatment should include HIV prevention interventions. To address this important research gap, this study evaluates the longitudinal prevalence and predictors of injection drug use (IDU) and sex risk behaviors among adolescents in substance treatment. Participants were 260 adolescents (13-18 years) in substance treatment and 201 community control adolescents (11-19 years). Participants were assessed at baseline and follow-up (mean time between assessments = 6.9 years for the clinical sample and 5.6 years for the community control sample). Outcomes included self-report lifetime history of IDU, number of lifetime sex partners and frequency of unprotected sexual intercourse. At baseline, 7.5% of the clinical sample, compared to 1.0% of the community control sample had a lifetime history of IDU (χ12=10.53, p = .001). At follow-up, 17.4% of the clinical sample compared to 0% of the community control sample had a lifetime history of IDU (χ12=26.61, p = .0005). The number of baseline substance use disorders and onset age of marijuana use significantly predicted the presence of lifetime IDU at follow-up, after adjusting for baseline age, race, and sex. The clinical sample reported more lifetime sex partners and more frequent unprotected sex than the community control sample at baseline and follow-up. Many adolescents in substance treatment develop IDU and report persistent risky sex. Effective risk reduction interventions for adolescents in substance treatment are needed that address both IDU and risky sex. Copyright © American Academy of Addiction Psychiatry.

    Depression is a global concern and it is well known that certain segments of the population are at greater risk. Sexual minorities are recognized as being more likely to suffer from depression due to social stigma and prejudice. The aim of this study was to describe the relationship between sexual orientation and depression in the Canadian population. The study used the 2012 Canadian Community Health Survey - Mental Health data. The sample comprised 24,788 Canadians living in the ten provinces. Logistic regression analyses were used to examine the relationship of depression and sexual orientation. After adjusting for known risk factors for depression, there was no difference in prevalence of past 12-month or lifetime major depressive episode between sexual minorities and heterosexuals. Bisexuals did have a near significant trend towards higher prevalence of both past 12-month and lifetime depression as a combined group, but there were not clear differences when stratified by sex. This study supports important emerging trends in the relationship between sexual orientation and depression. Research on the mental health of sexual minority people must take into account differences between sexual minority groups and avoid aggregating mental health disorders into broad categories. These findings have implications for public health planning and clinical recommendations.

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    The potential adverse consequences, personal distress, shame and guilt presented by patients who suffer from sexual addiction require a more in-depth understanding of the phenomenology and psychobiology of this disorder. A bibliographic review was conducted using MEDLINE and EBSCO databases with the following keywords: "sexual addiction," "hypersexuality," "compulsive sexual behavior," "behavioural addiction," "treatment," and "addiction." Several conceptualizations of excessive nonparaphilic sexual disorder have been proposed based on the models of, respectively, obsessive compulsive disorder, impulse control disorder, out of control excessive sexual disorder, and addictive disorder. Despite the lack of robust scientific data, a number of clinical elements, such as the frequent preoccupation with this type of behavior, the time spent in sexual activities, the continuation of this behavior despite its negative consequences, the repeated and unsuccessful efforts made to reduce the behavior, are in favor of an addictive disorder. In addition there is a high comorbidity between excessive sexual behavior and other addictive behaviors. The phenomenology of excessive nonparaphilic sexual disorder favors its conceptualization as an addictive behavior, rather than an obsessive-compulsive, or an impulse control disorder. Moreover, the criteria that are quite close to those of addictive disorders were recently proposed for the future DSM-V in order to improve the characterization of this condition. Finally, controlled studies are warranted in order to establish clear guidelines for treatment of sexual addiction.

    Examining a victim of sexual assault is a medico-legal emergency. It has to be performed within 72 h, in appropriate conditions. A recent laceration of the hymen does not necessarily indicate a rape, and conversely absence of trauma to a rape victim does not negate the validity of her claim to rape. A normal clinical examination does not exclude the possibility of a sexual abuse. Unlawful sexual intercourse is defined by a sexual penetration without valid consent. Specimen collection, to be considered as an evidence, must be sealed. Toxicological samples have to be performed to search a rape under influence.

  20. Internet Sexualities

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    This study tested a moderation model in which the association between child sexual abuse severity and negative sexual outcomes (i.e., sexual avoidance and compulsivity) differed as a function of relationships status (i.e., single, cohabiting, and married individuals). A sample of 1,033 adults completed self-report questionnaires online, and 21.5% reported childhood sexual abuse. Path analyses indicated that child sexual abuse severity was associated with higher sexual compulsivity in single individuals, both higher sexual avoidance and compulsivity in cohabiting individuals, and higher sexual avoidance in married individuals. The moderation model was invariant across men and women. These results suggest that the time course of negative sexual outcomes associated with child sexual abuse may follow distinct patterns of expression according to relationship status. © 2016 American Association for Marriage and Family Therapy.

    Full Text Available Background: The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. Objective: This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner’s sexual techniques. Design: In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18–54 years in 1971 (N=2,152, 18–74 years in 1992 (N=2,250, 18–81 years in 1999 (N=1,496, 18–74 years in 2007 (N=2,590, and 18–79 years in 2015 (N=2,150. Another dataset of 2,049 women in the age group of 18–70 years was collected in 2015 via a national Internet panel. Results: Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner’s orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner’s good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms. Conclusion: The findings indicate that women differ greatly from one another in terms of their tendency and capacity to experience orgasms. The

The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner's sexual techniques. In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18-54 years in 1971 (N=2,152), 18-74 years in 1992 (N=2,250), 18-81 years in 1999 (N=1,496), 18-74 years in 2007 (N=2,590), and 18-79 years in 2015 (N=2,150). Another dataset of 2,049 women in the age group of 18-70 years was collected in 2015 via a national Internet panel. Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner's orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner's good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms. The findings indicate that women differ greatly from one another in terms of their tendency and capacity to experience orgasms. The improvements in gender equality and sexual education since the 1970s have not helped women

    Ultra-violet (UV) fluorescence lifetime modification by aluminum (Al) and magnesium (Mg) nanoapertures are reported in this manuscript. Nanoapertures with diameter ranging from 30nm to 90nm are fabricated using focused ion beam (FIB). Largest lifetime reduction are observed for apertures with smallest diameters and undercuts into glass substrate. For Al nanoapertures, largest lifetime reduction is 5.30×, larger than perviously reported 3.50×.1 For Mg nanoapertures, largest lifetime reduction is 6.90×, which is the largest lifetime reduction of UV fluorescence dye reported so far in literature. The dependence of count rate per molecule (CRM) on aperture size and undercut is also investigated, revealing that CRM increases with increasing undercut, however, the CRM is small (less than 2) for the entire range of aperture size and undercut we investigated. FDTD simulation were conducted and in order to favorably compare experimental results with simulated results, it is critical to take into account the exact shape and material properties of the nano aperture. Simulation results revealed the fundamental difference between Al and Mg nano aperture under 266nm illumination-Mg nano aperture presents a waveguide mode in which the maximum field enhancement and Purcell factor is within the nano aperture instead of on the surface which is the case for Al nano aperture.

    Transient photoluminescence is used to measure the minority carrier lifetime on n-type and p-type InP wafers. The measurements show that unprocessed InP wafers have very high minority carrier lifetimes. Lifetimes of 200 ns and 700 ns were observed for lightly-doped p- and n-type material respectively. Lifetimes over 5 ns were found in heavily doped n-type material.

  7. Sexual and natural selection both influence male genital evolution.

    Directory of Open Access Journals (Sweden)

    Clarissa M House

    Full Text Available Rapid and divergent evolution of male genital morphology is a conspicuous and general pattern across internally fertilizing animals. Rapid genital evolution is thought to be the result of sexual selection, and the role of natural selection in genital evolution remains controversial. However, natural and sexual selection are believed to act antagonistically on male genital form. We conducted an experimental evolution study to investigate the combined effects of natural and sexual selection on the genital-arch lobes of male Drosophila simulans. Replicate populations were forced to evolve under lifetime monogamy (relaxed sexual selection or lifetime polyandry (elevated sexual selection and two temperature regimes, 25°C (relaxed natural selection or 27°C (elevated natural selection in a fully factorial design. We found that natural and sexual selection plus their interaction caused genital evolution. Natural selection caused some aspects of genital form to evolve away from their sexually selected shape, whereas natural and sexual selection operated in the same direction for other shape components. Additionally, sexual and natural selection tended to favour larger genitals. Thus we find that the underlying selection driving genital evolution is complex, does not only involve sexual selection, and that natural selection and sexual selection do not always act antagonistically.

    To describe suicide risk in youth seen at a Juvenile Assessment Center (JAC), we examined relationships among self-reported lifetime attempts and demographic, justice, and psychiatric data via logistic regression. Similar to other settings, youth reporting lifetime attempts were more likely to be older, female, not living with both parents and currently arrested for a violent or felony crime. Mood, substance use, and behavior disorder each increased prediction substantially. Anxiety Disorder was associated with elevated attempt rates for boys only. JACs need to develop protocols for identifying suicide risk; further, since suicide history predicts future attempts, Anxiety Disordered boys may be at particular risk.

    Radiative lifetimes are reported for 37 odd-parity energy levels of neutral niobium (Nb I), out of which 33 have been measured for the first time. The levels belong to electronic configurations 4d35s5p and 4d45p between 18,790 and 35,730 cm-1. The time-resolved laser-induced fluorescence spectroscopy technique was employed. The Nb atoms were generated in a free-jet by laser vaporization of niobium metal. Lifetime values reported in this work fall in the range 12-340 ns and are accurate to ±10%.

  10. Modernization, sexual risk-taking, and gynecological morbidity among Bolivian Forager-horticulturalists.

    Full Text Available Sexual risk-taking and reproductive morbidity are common among rapidly modernizing populations with little material wealth, limited schooling, minimal access to modern contraception and healthcare, and gendered inequalities in resource access that limit female autonomy in cohabiting relationships. Few studies have examined how modernization influences sexual risk-taking and reproductive health early in demographic transition. Tsimane are a natural fertility population of Bolivian forager-farmers; they are not urbanized, reside in small-scale villages, and lack public health infrastructure. We test whether modernization is associated with greater sexual risk-taking, report prevalence of gynecological morbidity (GM, and test whether modernization, sexual risk-taking and parity are associated with greater risk of GM. Data were collected from 2002-2010 using interviews, clinical exams, and laboratory analysis of cervical cells. We find opposing effects of modernization on both sexual risk-taking and risk of GM. Residential proximity to town and Spanish fluency are associated with greater likelihood of men's infidelity, and with number of lifetime sexual partners for men and women. However, for women, literacy is associated with delayed sexual debut after controlling for town proximity. Fifty-five percent of women present at least one clinical indicator of GM (n = 377; 48% present inflammation of cervical cells, and in 11% the inflammation results from sexually transmitted infection (trichomoniasis. Despite having easier access to modern healthcare, women residing near town experience greater likelihood of cervical inflammation and trichomoniasis relative to women in remote villages; women who are fluent in Spanish are also more likely to present trichomoniasis relative to women with moderate or no fluency. However, literate women experience lower likelihood of trichomoniasis. Parity has no effect on risk of GM. Our results suggest a net increase

    A simple 1 period lifetime model is specified in which schooling is part of the lifetime period. This implies that an adding-up constraint is imposed on the uses of time in the lifetime including schooling, which may induce a negative correlation between years of schooling and years in the market, while producing a positive correlation between years of schooling and the fraction of the postschool lifetime spent in the market. The model is used to interpret empirical analyses based on alternative measures of lifetime labor supply and on alternative specifications of which variables may be treated as exogenous. In the empirical analysis the retrospective and longitudinal aspects of the newly available National Longitudinal Survey of Women is used to construct a measure of the fraction of the lifetime supplied to the market and measures of the lifetime wage rates of both the husband and the wife. The empirical results take the lifetime model of labor supply seriously in that the empirical measures of labor supply and wage rates bear a much closer resemblance to the theoretical concepts than measures typically employed in the literature. The estimates indicate that the "plausible assumptions" required for the true coefficient on fertility in a labor supply equation to be zero are fulfilled. These estimates are compared with those obtained using current measures as proxies for lifetime variables. Based on these estimates, an explanation is offered for the apparent contradiction between the findings of studies using a simultaneous equations approach that report no effect of fertility on female labor supply and the strong depressing effect of children on (current) labor supply obtained from research that treats children as exogenous. Current female hours appear more responsive to husbands' current earnings and female education than is the case with the lifetime variables. There are marked differences in the effects of race. The lifetime hours of white women are only some

    The use of social networking applications (apps) on smartphones has the potential to impact sexual health and behaviour. This was the first systematic review to critically appraise and summarize the existing literature on the use of social networking apps on smartphones and their associated sexual health and sexual behaviour effects in lesbian, gay, bisexual and transgender populations. A systematic search was conducted in five databases (CINAHL Plus, PsycINFO, PubMed, SCOPUS and Sociological Abstracts), using controlled terms and keywords. Thirteen articles from 11 studies were included in this review. Studied outcomes included rates of unprotected sexual intercourse, the number of sexual partners, drug/alcohol use prior to/during sexual intercourse, sexually transmitted infections (STIs) testing and the prevalence of STIs. Among app users, the prevalence of unprotected sex ranged from 17.0% to 66.7%. The mean number of sexual partners ranged from 1.4 to 2.9 (last 1-month period), and from 46.2 to 79.6 (lifetime). Two studies found that the prevalence of HIV infection was 1.9% and 11.4%, respectively. The self-reported prevalence of prior diagnosis of STIs other than HIV ranged from 9.1% to 51.0%. It should be noted that the heterogeneity of the study design and outcome measures across different studies hindered the comparison of findings across different studies. Furthermore, the findings in some studies are not reliable due to methodological problems. Our results highlight the need for more research with rigorous methodology to understand the negative impacts of using these apps on sexual health and sexual behaviour. For future studies, the operational definition of outcomes, including social networking app use and unprotected anal intercourse (UAI), should be clearly outlined. The use of validated tools to measure sexual behaviour and biological measures of HIV and other STDs is preferable so that outcomes can be standardized to facilitate comparisons between

    The most precise determination of the neutron lifetime using the beam method was completed in 2005 and reported a result of tau_n = (886.3 +/- 1.2 [stat] +/- 3.2 [sys]) s. The dominant uncertainties were attributed to the absolute determination of the fluence of the neutron beam (2.7 s). The fluence was measured with a neutron monitor that counted the neutron-induced charged particles from absorption in a thin, well-characterized 6Li deposit. The detection efficiency of the monitor was calculated from the areal density of the deposit, the detector solid angle, and the ENDF/B-VI 6Li(n,t)4He thermal neutron cross section. In the current work, we have measured the detection efficiency of the same monitor used in the neutron lifetime measurement with a second, totally-absorbing neutron detector. This direct approach does not rely on the 6Li(n,t)4He cross section or any other nuclear data. The detection efficiency is consistent with the value used in 2005 but was measured with a precision of 0.057 %, which represe...

    ANSYS/CARES/PDS is a software system that combines the ANSYS Probabilistic Design System (PDS) software with a modified version of the Ceramics Analysis and Reliability Evaluation of Structures Life (CARES/Life) Version 6.0 software. [A prior version of CARES/Life was reported in Program for Evaluation of Reliability of Ceramic Parts (LEW-16018), NASA Tech Briefs, Vol. 20, No. 3 (March 1996), page 28.] CARES/Life models effects of stochastic strength, slow crack growth, and stress distribution on the overall reliability of a ceramic component. The essence of the enhancement in CARES/Life 6.0 is the capability to predict the probability of failure using results from transient finite-element analysis. ANSYS PDS models the effects of uncertainty in material properties, dimensions, and loading on the stress distribution and deformation. ANSYS/CARES/PDS accounts for the effects of probabilistic strength, probabilistic loads, probabilistic material properties, and probabilistic tolerances on the lifetime and reliability of the component. Even failure probability becomes a stochastic quantity that can be tracked as a response variable. ANSYS/CARES/PDS enables tracking of all stochastic quantities in the design space, thereby enabling more precise probabilistic prediction of lifetimes of ceramic components.

    Despite shifts toward greater acceptance in U.S. public opinion and policy, lesbian, gay, and bisexual people remain widely stigmatized. This article reviews empirical research on sexual prejudice, that is, heterosexuals' internalization of cultural stigma, manifested in the form of negative attitudes toward sexual minorities and same-sex desires and behaviors. After briefly reviewing measurement issues, we discuss linkages between sexual prejudice and religion, gender, sexuality, and related variables, and consider how the cultural institutions encompassing these domains create a social context within which individual expressions of prejudice can meet important psychological needs. These include needs for securing social acceptance, affirming values that are central to one's self-concept, and avoiding anxiety and other negative emotions associated with threats to self-esteem. We conclude by discussing factors that may motivate heterosexuals to reduce their own sexual prejudice, including intergroup contact, as well as avenues for future empirical inquiry.

    New radiative lifetimes are reported for 168 levels of V I ranging in energy from 18086 cm{sup –1} to 47702 cm{sup –1}, and for 31 levels of V II ranging in energy from 34593 cm{sup –1} to 47420 cm{sup –1}. These lifetimes are measured using time-resolved laser-induced fluorescence on a slow atomic/ionic beam as part of an ongoing study of the radiative properties of the iron group elements. All but two of the V II lifetimes have been measured before using modern laser-based methods, but a large fraction of the V I lifetimes are reported here for the first time. Comparison to earlier measurements is discussed. These new lifetimes are, for the most part, accurate to ±5%. They will be combined with branching fraction measurements to produce a large set of transition probabilities for V I and V II which are needed by the astrophysics community for stellar abundance determinations.

    The carrier lifetimes in thin-film solar cells are reviewed and discussed. Shockley-Read-Hall recombination is dominant at low carrier density, Auger recombination is dominant under a high injection condition and high carrier density, and surface recombination is dominant under any conditions. Because the surface photovoltage technique is insensitive to the surface condition, it is useful for bulk lifetime measurements. The photoconductance decay technique measures the effective recombination lifetime. The time-resolved photoluminescence technique is very useful for measuring thin-film semiconductor or solar-cell materials lifetime, because the sample is thin, other techniques are not suitable for measuring the lifetime. Many papers have provided time-resolved photoluminescence (TRPL) lifetimes for copper-indium-gallium-selenide (CIGS) and CdTe thin-film solar cell. The TRPL lifetime strongly depends on open-circuit voltage and conversion efficiency; however, the TRPL life time is insensitive to the short-circuit current.

    2017-01-01

    An interesting property of some neutron-unbound systems is true two-neutron emission where the neutrons are emitted simultaneously as opposed to a sequential decay through an intermediate state. Since neutrons are only affected by the angular momentum barrier, the timescale for this process is much shorter than for two proton emission which is dominated by the Coulomb barrier. One such case is 26O where a very low decay energy was measured and the two valence neutrons are expected to occupy d-wave orbitals. Also, the ground state of 25O is located 700 keV higher. In a first experiment, the MoNA collaboration extracted a lifetime of 4 .5-1 . 5 + 1 . 1 (stat) +/- 3(syst) ps with a confidence level of 82%. Recently, an experiment dedicated to measuring the 26O lifetime in order to improve the confidence level of the measurement was performed at NSCL. The experiment utilized a newly developed segmented target which increased the statistics without degrading the resolution. Preliminary results will be presented.

    2007-01-01

    Lifetime Testing of Corrosion Preventive Compounds (CPCs) was performed to quantify performance in the various environments to which the Space Shuttle Orbiter is exposed during a flight cycle. Three CPCs are approved for use on the Orbiter: RD Calcium Grease, Dinitrol AV-30, and Braycote 601 EF. These CPCs have been rigorously tested to prove that they mitigate corrosion in typical environments, but little information is available on how they perform in the unique combination of the coastal environment at the launch pad, the vacuum of low-earth orbit, and the extreme heat of reentry. Currently, there is no lifetime or reapplication schedule established for these compounds that is based on this combination of environmental conditions. Aluminum 2024 coupons were coated with the three CPCs and exposed to conditions that simulate the environments to which the Orbiter is exposed. Uncoated Aluminum 2024 coupons were exposed to the environmental conditions as a control. Visual inspection and Electro- Impedance Spectroscopy (EIS) were performed on the samples in order to determine the effectiveness of the CPCs. The samples were processed through five mission life cycles or until the visual inspection revealed the initiation of corrosion and EIS indicated severe degradation of the coating.

    Full Text Available For the measurement of the minority carrier bulk-lifetime the characterization method MW-PCD is used, where the result of measurement is the effective carrier lifetime, which is very dependent on the surface recombination velocity and therefore on the quality of a silicon surface passivation. This work deals with an examination of a different solution types for the chemical passivation of a silicon surface. Various solutions are tested on silicon wafers for their consequent comparison. The main purpose is to find optimal solution, which suits the requirements of a time stability and start-up velocity of passivation, reproducibility of the measurements and a possibility of a perfect cleaning of a passivating solution remains from a silicon surface, so that the parameters of a measured silicon wafer will not worsen and there will not be any contamination of the other wafers series in the production after a repetitive return of the measured wafer into the production process. The cleaning process itself is also a subject of a development.

    Full Text Available Abstract Background Japanese men who have sex with men (MSM, especially those living in large metropolitan areas such as Tokyo and Osaka, are facing a growing HIV/AIDS epidemic. Although the Internet is used as a new venue for meeting sex partners, it can also serve as a useful research tool for investigating the risk behaviours of Japanese MSM. This Internet survey explored the extent of substance use and its association with sexual risk behaviours among Japanese MSM. Methods Between 28 February 2003 and 16 May 2003 MSM were recruited through 57 Japanese gay-oriented Web sites, gay magazines, and Internet mailing lists. Participants completed a structured questionnaire anonymously through the Internet. Results In total, 2,062 Japanese MSM completed the questionnaire. The average age of participants was 29.0 years and 70.5% identified as gay, 20.8% as bisexual, and 8.7% as other. Overall, 34.5% reported never using a substance, 45% reported ever using one type of substance (lifetime reported single substance users, and 19.6% had used more than 1 type of substance (lifetime reported multiple substance users in their lifetimes. The substances most commonly used were amyl nitrite (63.2%, 5-methoxy-N, N-diisopropyltryptamine (5MEO-DIPT (9.3%, and marijuana (5.7%. In the multivariate analysis, unprotected anal intercourse, having had 6 or more sexual partners, visiting a sex club/gay venue in the previous 6 months, a lower education level, and being 30 to 39 years of age were associated with both lifetime single and lifetime multiple substance use. Lifetime reported multiple substance use was also correlated with having a casual sex partner, having symptoms of depression, being diagnosed as HIV-positive, and greater HIV/AIDS-related knowledge. Conclusion This is the first Internet-based research focused on the sexual and substance use behaviours of MSM in Asia. Our findings suggest a compelling need for prevention interventions to reduce HIV risk

    Male sexual dysfunction is a prevalent and distressing condition, which may be exacerbated by the sufferer's perceptions of masculinity and normative sexual behavior. This study sought to investigate the effect of social context on males' beliefs regarding sexual behavior. The research examined the effect of male role modeling and masculine cues on males' dysfunctional sexual beliefs, sexual attitudes, and self-perceptions of sexual functioning. A sample of 140 male participants, with a mean age of 29 years, was exposed to pictorial and verbal cues that presented different versions of male behavior across three conditions. Results indicated that males exposed to models and cues of traditional masculinity showed significantly increased levels of dysfunctional sexual beliefs and traditional sexual attitudes relative to males exposed to models of modern masculinity. Results also indicated that males exposed to traditional masculine stimuli reported lower levels of sexual inhibition due to fear of performance failure than males exposed to models of modern masculinity. The potential role of social context is discussed in the development and maintenance of male sexual dysfunction and its implications for treatment.

    Emerging research suggests sexual media affects sexual behavior, but most studies are based on regional samples and few include measures of newer mediums. Furthermore, little is known about how sexual media relates to sexual violence victimization. Data are from 1058 youth 14 to 21 years of age in the national, online Growing up with Media study. Forty-seven percent reported that many or almost all/all of at least one type of media they consumed depicted sexual situations. Exposure to sexual media in television and movies, and music was greater than online and in games. All other things equal, more frequent exposure to sexual media was related to ever having had sex, coercive sex victimization, and attempted/completed rape but not risky sexual behavior. Longer standing mediums such as television and movies appear to be associated with greater amounts of sexual media consumption than newer ones, such as the Internet. A nuanced view of how sexual media content may and may not be affecting today's youth is needed. © The Author(s) 2014.

    Full Text Available The aim of this study was to examine characterisctics of precoital sexual behaviors and types of sexual contact in adolescent. A representative sample of 4,456 Spanish high school students participated. These participants were selected by means of a stratified random sampling procedure. They completed a questionnaire about their sexual behaviour. It is a cross-sectional survey study. Differences according to age and gender in characteristics of sexualbehaviour before the onset of sexual intercourse were found. Comparedto females, males started non penetrative sexual experiences earlier, had a higher number of sexual partners and a higher percentage of males reported having had casual sexual partner. This study not only adds to knowledge about sexual behaviour before the initiation of sexual intercourse among adolescents, it also highlights the importance of developing sexual prevention strategies for young adolescents.

    Despite the World Health Organization's definition of sexual health as a state of well-being, virtually no public health research has examined sexual well-being outcomes, including sexual satisfaction. Emerging evidence suggests that sexual well-being indicators are associated with more classic measures of healthy sexual behaviors. We surveyed 2168 university students in the United States and asked them to rate their physiological and psychological satisfaction with their current sexual lives. Many respondents reported that they were either satisfied (approximately half) or very satisfied (approximately one third). In multivariate analyses, significant (P self-comfort, self-esteem (especially among men), relationship status, and sexual frequency. To enhance sexual well-being, public health practitioners should work to improve sexual self-comfort, alleviate sexual guilt, and promote longer term relationships.

  14. A novel measurement of $B^0_s$ and $D^-_s$ lifetimes using semileptonic decays at LHCb arXiv

    I report new, world-leading LHCb results on heavy meson lifetimes. We use a novel approach that suppresses the shortcomings typically associated with reconstruction of semileptonic decays, allowing for precise measurements of lifetimes and other properties in collider experiments. We achieve a 15% and a $2\\times$ improvement over current best determinations of the flavor-specific $B^0_s$ lifetime and $D^-_s$ lifetime, respectively.

  15. Sexuality and its object in Freud's 1905 edition of Three Essays on the Theory of Sexuality.

    Freud's Three Essays on the Theory of Sexuality is one of the grounding texts of 20th century European thinking. In it Freud develops a highly original theory of sexuality for which hysteria (and pathology in general) serves a model to understand human existence. Freud published this text five times during his lifetime. This article wants to reconstruct the first edition with regard to the status and nature of (infantile) sexuality in relation to its object. It investigates how and why this relation changes in the different versions of the text. The reconstruction of the first edition is a crucial, but often forgotten task to understand the genesis of Freudian thinking.

    College women frequently report having experienced sexual victimization (SV) in their lifetime, including child sexual abuse and adolescent/adult sexual assault. Although the harmful mental health sequelae of SV have been extensively studied, recent research suggests that SV is also a risk factor for poorer college academic performance. The current studies examined whether exposure to SV uniquely predicted poorer college academic performance, even beyond contributions from three well-established predictors of academic performance: high school rank, composite standardized test scores (i.e., American College Testing [ACT]), and conscientiousness. Study 1 analyzed longitudinal data from a sample of female college students (N = 192) who were assessed at the beginning and end of one semester. SV predicted poorer cumulative end-of-semester grade point average (GPA) while controlling for well-established predictors of academic performance. Study 2 replicated these findings in a second longitudinal study of female college students (N = 390) and extended the analyses to include follow-up data on the freshmen and sophomore students (n = 206) 4 years later. SV predicted students' GPA in their final term at the university above the contributions of well-established academic predictors, and it was the only factor related to leaving college. These findings highlight the importance of expanding the scope of outcomes of SV to include academic performance, and they underscore the need to assess SV and other adverse experiences on college campuses to target students who may be at risk of poor performance or leaving college.

  17. Sexual Victimization, Alcohol Intoxication, Sexual-Emotional Responding, and Sexual Risk in Heavy Episodic Drinking Women

    This study used an experimental paradigm to investigate the roles of sexual victimization history and alcohol intoxication in young women’s sexual-emotional responding and sexual risk taking. A nonclinical community sample of 436 young women, with both an instance of heavy episodic drinking and some HIV/STI risk exposure in the past year, completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. A majority of them reported CSA and/or ASA, including rape and attempted rape. After random assignment to a high alcohol dose (.10%) or control condition, participants read and projected themselves into an eroticized scenario of a sexual encounter involving a new partner. As the story protagonist, each participant rated her positive mood and her sexual arousal, sensation, and desire, and then indicated her likelihood of engaging in unprotected sex. Structural equation modeling analyses revealed that ASA and alcohol were directly associated with heightened risk taking, and alcohol’s effects were partially mediated by positive mood and sexual desire. ASA was associated with attenuated sexual-emotional responding and resulted in diminished risk taking via this suppression. These are the first findings indicating that, compared to non-victimized counterparts, sexually victimized women respond differently in alcohol-involved sexual encounters in terms of sexual-emotional responding and risk-taking intentions. Implications include assessing victimization history and drinking among women seeking treatment for either concern, particularly women at risk for HIV, and alerting them to ways their histories and behavior may combine to exacerbate their sexual risks.

    This paper emphasizes four topics that represent some of the year's highlights in heavy quark physics. First of all, a review is given of charm lifetime measurements and how they lead to better understanding of the mechanisms of charm decay. Secondly, the CLEO collaboration's new search for charm mixing is reported, which significantly extends the search for new physics in that sector. Thirdly, important updates in Bs mixing are summarized, which result in a new limit on the mass difference, and which further constrain the unitarity triangle. Finally, the first efforts to measure CP violation in the B system are discussed. Results are shown for the CDF and ALEPH measurements of sin(2beta), as well as the CLEO branching fraction measurements of B-->Kpi,pipi, which have implications for future measurements of alpha.

    The calibration standards used in the Atmospheric Lifetime Experiment (ALE) for CFCl3, CF2Cl2, CH3CCl3, and CCl4 are described. This includes the preparation of the primary standards by static dilution and their propagation and stability for the period 1977-1982. Two independent assessments of the absolute concentrations of the primary standards used to initiate the ALE measurements in 1977-1978 are reported. For consistency in the ALE program the values assigned to the primary standards and subsequent working standards used in the field were not altered during the experiment when results of better estimates of the original concentration values were obtained. Rather, the appropriate factors by which the ALE mixing ratios for a given species should be multiplied to obtain the best estimate of the current concentration of a given species, are provided.
