    This study examined the independent and interactive effects of sexual explicitness and degrading themes toward women on mens' attitudes following exposure to video presentations of male-female interactions. Subjects were 83 male college students who viewed video vignettes under one of four stimulus conditions: (a) sexually explicit/degrading, (b) sexually explicit/nondegrading, (c) nonexplicit/degrading, and (d) nonexplicit/nondegrading. Results revealed that men exposed to degrading material, regardless of explicitness, were significantly more likely to express attitudes supportive of rape, while explicitness had no significant main or interactive effect on these attitudes. Further, the interaction of explicitness with degradation was found to impact scores on a measure of sexual callousness. Theoretical and clinical implications of these findings are discussed.

    Sexually explicit material (SEM) (including Internet, video, and print) may play a key role in the lives of Black same-sex sexually active youth by providing the only information to learn about sexual development. There is limited school- and/or family-based sex education to serve as models for sexual behaviors for Black youth. We describe the role SEM plays in the sexual development of a sample of Black same-sex attracted (SSA) young adolescent males ages 15-19. Adolescents recruited from clinics, social networking sites, and through snowball sampling were invited to participate in a 90-min, semi-structured qualitative interview. Most participants described using SEM prior to their first same-sex sexual experience. Participants described using SEM primarily for sexual development, including learning about sexual organs and function, the mechanics of same-gender sex, and to negotiate one's sexual identity. Secondary functions were to determine readiness for sex; to learn about sexual performance, including understanding sexual roles and responsibilities (e.g., "top" or "bottom"); to introduce sexual performance scripts; and to develop models for how sex should feel (e.g., pleasure and pain). Youth also described engaging in sexual behaviors (including condom non-use and/or swallowing ejaculate) that were modeled on SEM. Comprehensive sexuality education programs should be designed to address the unmet needs of young, Black SSA men, with explicit focus on sexual roles and behaviors that may be inaccurately portrayed and/or involve sexual risk-taking (such as unprotected anal intercourse and swallowing ejaculate) in SEM. This work also calls for development of Internet-based HIV/STI prevention strategies targeting young Black SSA men who may be accessing SEM. PMID:25677334

  10. Methodological issues in defining aggression for content analyses of sexually explicit material.

    PubMed

    McKee, Alan

    2015-01-01

    There exists an important tradition of content analyses of aggression in sexually explicit material. The majority of these analyses use a definition of aggression that excludes consent. This article identifies three problems with this approach. First, it does not distinguish between aggression and some positive acts. Second, it excludes a key element of healthy sexuality. Third, it can lead to heteronormative definitions of healthy sexuality. It would be better to use a definition of aggression such as Baron and Richardson's (1994) in our content analyses, that includes a consideration of consent. A number of difficulties have been identified with attending to consent but this article offers solutions to each of these. PMID:24609608

    This study had three goals: first, to investigate whether sexually explicit Internet material (SEIM) affects sexual risk behavior; second, to study whether these effects differ between adolescents and adults; and third, to analyze, separately for adolescents and adults, whether gender and age moderate an influence of SEIM on sexual risk behavior. The authors conducted a 2-wave panel survey among nationally representative random samples of 1,445 Dutch adolescents and 833 Dutch adults. SEIM use increased sexual risk behavior among adults, but not among adolescents. More specifically, moderator analyses showed that SEIM use increased sexual risk behavior only among male adults, but not among female adults. In the adolescent sample, no moderating gender effect occurred. Neither among adolescents nor among adults did age moderate the effects. Our study shows that SEIM may influence outcomes related to people's sexual health. It also suggests that male adults may present a potential risk group for adverse effects of SEIM. PMID:21476164

    Although research has repeatedly demonstrated that adolescents' use of sexually explicit Internet material (SEIM) is related to their endorsement of permissive sexual attitudes and their experience with sexual behavior, it is not clear how linkages between these constructs unfold over time. This study combined 2 types of longitudinal modeling, mean-level development and cross-lagged panel modeling, to examine (a) developmental patterns in adolescents' SEIM use, permissive sexual attitudes, and experience with sexual behavior, as well as whether these developments are related; and (b) longitudinal directionality of associations between SEIM use on the 1 hand and permissive sexual attitudes and sexual behavior on the other hand. We used 4-wave longitudinal data from 1,132 7th through 10th grade Dutch adolescents (M(age) T1 = 13.95; 52.7% boys) and estimated multigroup models to test for moderation by gender. Mean-level developmental trajectories showed that boys occasionally and increasingly used SEIM over the 18-month study period, which co-occurred with increases in their permissive attitudes and their experience with sexual behavior. Cross-lagged panel models revealed unidirectional effects from boys' SEIM use on their subsequent endorsement of permissive attitudes, but no consistent directional effects between their SEIM use and sexual behavior. Girls showed a similar pattern of increases in experience with sexual behavior, but their SEIM use was consistently low and their endorsement of permissive sexual attitudes decreased over the 18-month study period. In contrast to boys, girls' SEIM use was not longitudinally related to their sexual attitudes and behavior. Theoretical and practical implications of these gender-specific findings are discussed.

    2010-01-01

    This study investigated associations between viewing sexually-explicit material (SEM) and relationship functioning in a random sample of 1291 unmarried individuals in romantic relationships. More men (76.8%) than women (31.6%) reported that they viewed SEM on their own, but nearly half of both men and women reported sometimes viewing SEM with their partner (44.8%). Measures of communication, relationship adjustment, commitment, sexual satisfaction, and infidelity were examined. Individuals who never viewed SEM reported higher relationship quality on all indices than those who viewed SEM alone. Those who viewed SEM only with their partners reported more dedication and higher sexual satisfaction than those who viewed SEM alone. The only difference between those who never viewed SEM and those who viewed it only with their partners was that those who never viewed it had lower rates of infidelity. Implications for future research in this area as well as for sex therapy and couple therapy are discussed. PMID:20039112

    Although a growing body of literature addresses the effects of young people's use of sexually explicit Internet material, research on the compulsive use of this type of online content among adolescents and its associated factors is largely lacking. This study investigated whether factors from three distinct psychosocial domains (i.e., psychological well-being, sexual interests/behaviors, and impulsive-psychopathic personality) predicted symptoms of compulsive use of sexually explicit Internet material among adolescent boys. Links between psychosocial factors and boys' compulsive use symptoms were analyzed both cross-sectionally and longitudinally with compulsive use symptoms measured 6 months later (T2). Data were used from 331 Dutch boys (M age = 15.16 years, range 11-17) who indicated that they used sexually explicit Internet material. The results from negative binomial regression analyses indicated that lower levels of global self-esteem and higher levels of excessive sexual interest concurrently predicted boys' symptoms of compulsive use of sexually explicit Internet material. Longitudinally, higher levels of depressive feelings and, again, excessive sexual interest predicted relative increases in compulsive use symptoms 6 months later. Impulsive and psychopathic personality traits were not uniquely related to boys' symptoms of compulsive use of sexually explicit Internet material. Our findings, while preliminary, suggest that both psychological well-being factors and sexual interests/behaviors are involved in the development of compulsive use of sexually explicit Internet material among adolescent boys. Such knowledge is important for prevention and intervention efforts that target the needs of specific problematic users of sexually explicit Internet material. PMID:26208829

    Previous research on women's responses to male-targeted sexually explicit material (SEM) suggests that women may be critical toward such content. However, women's critical responses to SEM have not been explained empirically. The present study had two goals: (1) to investigate whether women's critical responses to male-targeted SEM depend on individual differences in gender role orientation (i.e., hyperfemininity) and (2) to explain the effect of hyperfemininity on critical responses to SEM by looking at the way sexual material is processed. In an online experiment among women aged 18 to 30 (N = 195), both the type of SEM (a male- versus female-targeted erotic story) and processing style (stimulus- versus response-focused) were manipulated. In addition, participants were divided into three groups based on low, moderate, or high hyperfemininity. When using stimulus-focused processing (i.e., attending to the characters and situational context of the story), women were more critical toward male-targeted SEM (relative to female-targeted material), but only when they had low and moderate degrees of hyperfemininity.

  17. The influence of sexually explicit Internet material and peers on stereotypical beliefs about women's sexual roles: similarities and differences between adolescents and adults.

    2011-09-01

    Previous research on the influence of sexually explicit Internet material (SEIM) on adolescents' stereotypical beliefs about women's sexual roles has three shortcomings. First, the role of peers has been neglected; second, stereotypical beliefs have rarely been studied as causing the use of SEIM and the selection of specific peers; and third, it is unclear whether adolescents are more vulnerable to the effects of SEIM than adults. We used data from two nationally representative two-wave panel surveys among 1,445 Dutch adolescents and 833 Dutch adults, focusing on the stereotypical belief that women engage in token resistance to sex (i.e., the notion that women say "no" when they actually intend to have sex). Structural equation modeling showed that peers who supported traditional gender roles elicited, both among adolescents and adults, stronger beliefs that women use token resistance to sex. Further, the belief that women engage in token resistance predicted adolescents' and adults' selection of gender-role traditional peers, but it did not predict adolescents' and adults' use of SEIM. Finally, adults, but not adolescents, were susceptible to the impact of SEIM on beliefs that women engage in token resistance to sex. PMID:21332367

    2016-02-01

    This article examines individual variability in sexual desire and sexual satisfaction by exploring the relation between these sexual aspects and sexual attitudes (implicit and explicit) and by taking gender into account, as this has been shown to be an influential factor. A total of 28 men and 33 women living in heterosexual relationships completed questionnaires assessing sexual desire (dyadic, solitary), sexual satisfaction, and explicit sexual attitudes. An adapted version of the Affect Misattribution Procedure was used to assess implicit sexual attitudes. Results showed higher levels of dyadic and solitary sexual desire in men than in women. No gender differences were found regarding sexual satisfaction or sexual attitudes. High dyadic sexual desire was associated with positive implicit and explicit sexual attitudes, regardless of gender. However, solitary sexual desire was significantly higher in men than women and was associated, in women only, with positive implicit sexual attitudes, suggesting that solitary sexual desire may fulfill different functions in men and women. Finally, sexual satisfaction depended on the combination of explicit and implicit sexual attitudes in both men and women. This study highlights the importance of considering both implicit and explicit sexual attitudes to better understand the mechanisms underlying individual variability in sexual desire and satisfaction.

    1978-09-01

    This study focused on the specific effects of explicit and nonexplicit sexual stimuli on anxious, coitally inexperienced women. Using Bandura's social learning theory as the thoretical framework, the consequences of modeling behavior on an individual's response patterns were examined. Responses indicating sexual anxiety level, preferred sexual behavior, and manifest anxiety level were recorded. Forty-five women were selected based on their scores on the Short Manifest Anxiety Scale. The subjects were then randomly placed into three treatment groups: explicit, nonexplicit, and control. Analysis of the data revealed significant differences among the women in each of the three groups regarding sexual behavior. Sexual anxiety levels also differed between women in the explicit and control groups. Pre- and posttest manifest anxiety scores also showed a significant difference in the explicit-group women. It has been shown that anxious, coitally inexperienced women who are exposed to sexually explicit stimuli in a controlled situation will have lower sexual anxiety levels, have lowered manifest anxiety levels, and be more willing to participate in a greater variety of sexual behaviors under appropriate circumstances. The results of this study may aid those in the helping professions gain a better understanding of the effects sexual stimuli have on certain individuals. PMID:568923

    A material model logic structure has been developed which is useful for most explicit finite-difference and explicit finite-element Lagrange computer codes. This structure has been implemented and tested in the STEALTH codes to provide an example for researchers who wish to implement it in generically similar codes. In parallel with these models, material parameter libraries have been created for the implemented models for materials which are often needed in DoD applications.

    Research into why people choose not to use condoms despite a growing AIDS epidemic has tapped the attitude that the use of condoms somehow interferes with the progression of the sexual act or lessens sexual pleasure. The current study investigated the effects on male sexual arousal of condom use described in sexually explicit audiotaped narratives. The sexual arousal of 14 male university students was measured physiologically by penile plethysmography and by self-report using a within-subjects design. Subjects listened to 10 audiotaped scripts, half of which included the use of a condom and half of which did not. No significant differences in either physiological or subjective arousal data were found between conditions. PMID:8743622

    Compulsive sexual behaviour (CSB) is relatively common and has been associated with significant distress and psychosocial impairments. CSB has been conceptualized as either an impulse control disorder or a non-substance ‘behavioural’ addiction. Substance use disorders are commonly associated with attentional biases to drug cues which are believed to reflect processes of incentive salience. Here we assess male CSB subjects compared to age-matched male healthy controls using a dot probe task to assess attentional bias to sexually explicit cues. We show that compared to healthy volunteers, CSB subjects have enhanced attentional bias to explicit cues but not neutral cues particularly for early stimuli latency. Our findings suggest enhanced attentional bias to explicit cues possibly related to an early orienting attentional response. This finding dovetails with our recent observation that sexually explicit videos were associated with greater activity in a neural network similar to that observed in drug-cue-reactivity studies. Greater desire or wanting rather than liking was further associated with activity in this neural network. These studies together provide support for an incentive motivation theory of addiction underlying the aberrant response towards sexual cues in CSB. PMID:25153083

    OBJECTIVES: Sexting (sending/receiving sexually explicit texts and images via cell phone) may be associated with sexual health consequences among adolescents. However, to date, no published data from a probability-based sample has examined associations between sexting and sexual activity. METHODS: A probability sample of 1839 students was collected alongside the 2011 Youth Risk Behavior Survey in Los Angeles high schools. Logistic regressions were used to assess the correlates of sexting behavior and associations between sexting and sexual risk-taking. RESULTS: Fifteen percent of adolescents with cell phone access reported sexting, and 54% reported knowing someone who had sent a sext. Adolescents whose peers sexted were more likely to sext themselves (odds ratio [OR] = 16.87, 95% confidence interval [CI]: 9.62–29.59). Adolescents who themselves sexted were more likely to report being sexually active (OR = 7.17, 95% CI: 5.01–10.25). Nonheterosexual students were more likely to report sexting (OR = 2.74, 95% CI: 1.86–4.04), sexual activity (OR = 1.52, 95% CI: 1.07–2.15), and unprotected sex at last sexual encounter (OR = 1.84, 95% CI: 1.17–2.89). CONCLUSIONS: Sexting, rather than functioning as an alternative to “real world” sexual risk behavior, appears to be part of a cluster of risky sexual behaviors among adolescents. We recommend that clinicians discuss sexting as an adolescent-friendly way of engaging patients in conversations about sexual activity, prevention of sexually transmitted infections, and unwanted pregnancy. We further recommend that discussion about sexting and its associated risk behavior be included in school-based sexual health curricula. PMID:22987882

    The Internet offers an invaluable opportunity to re-imagine ideas, constructs and disciplines to create innovative sexual health promotion interventions. To gain insight into what young adults (aged 19-28) may be seeking in online sexual resources and approaches, this study explored how young people perceived their sexual health to be influenced by their consumption of the highly utilised sexual medium of Sexually Explicit Internet Movies [SEIM]. Employing an exploratory, qualitative methodology, data were collected through semi-structured interviews with 12 urban, heterosexual young adults, who self-identified as having consumed SEIM for a period of at least one year. All interviews were audiotaped with permission, transcribed verbatim and the data were analysed to identify emergent thematic concepts. Participants described utilising SEIM as an all-inclusive sexual forum to learn more about the positive aspects of sexual health, in a context that they viewed as being devoid of alternatives. Young adults' perceptions of the utility of SEIM suggest that it would be beneficial to create novel, sex-positive online sexual health interventions. Further exploration is clearly warranted on how Internet resources that are related to sexual health, such as SEIM, can be utilised to facilitate innovative approaches to online sexual health promotion.

    Sexually explicit media (SEM) have been used in HIV-prevention advertisements to engage men who have sex with men (MSM) and to communicate content. These advertisements exist within larger discourses, including a dominant heteronormative culture and a growing homonormative culture. Cognizant of these hegemonic cultures, this analysis examined the acceptable level of sexual explicitness in prevention advertisements. Seventy-nine MSM participated in 13 online focus groups, which were part of a larger study of SEM. Three macro themes-audience, location, and community representation-emerged from the analysis, as did the influence of homonormativity on the acceptability of SEM in HIV-prevention messages.

    The present study examines the short-term cognitive effects of playing a sexually explicit video game with female "objectification" content on male players. Seventy-four male students from a university in California, U.S. participated in a laboratory experiment. They were randomly assigned to play either a sexually-explicit game or one of two control games. Participants' cognitive accessibility to sexual and sexually objectifying thoughts was measured in a lexical decision task. A likelihood-to-sexually-harass scale was also administered. Results show that playing a video game with the theme of female "objectification" may prime thoughts related to sex, encourage men to view women as sex objects, and lead to self-reported tendencies to behave inappropriately towards women in social situations.

    2012-01-01

    Introduction Researchers have proposed that consumption of Sexually Explicit Media (SEM) may not only adversely influence sexual attitudes and behaviors of Men Who Have Sex with Men (MSM) but (also) play a positive role in the development and sexual education of MSM, be a major source of sexual information for MSM, and provide validation, understanding, and confirmation of MSM’s sexual orientation. However, such claims are in urgent need of empirical validation as is the development of psychometrically sound and easily implemented instruments able to reliably assist such validations. Aim To investigate how MSM who consume SEM self-perceive the impact of SEM on their STI-related sexual risk behaviors (i.e. anal intercourse), sexual knowledge, enjoyment of sex, interest in sex, attitudes toward sex, and understanding of their sexual orientation. Further, to provide a thorough psychometric validation of a reduced and reworked version of the Pornography Consumption Effect Scale. Main Outcomes Measures A revised version of the Pornography Consumption Effect Scale (PCES) by Hald and Malamuth (2008). Results This study found that 97% of MSM reported positive effects of SEM consumption on their sexual knowledge, enjoyment of and interest in sex, attitudes toward sex, and understanding of their sexual orientation. Only 3 % reported any negative effects of their SEM consumption. SEM consumption was found to significantly increase consumers’ interest in having protected anal intercourse while not significantly influencing their interests in having unprotected anal intercourse. The revised version of the PCES showed excellent psychometric performance. Conclusion The study found that MSM generally report positive effects of their consumption of sexually explicit materials in areas related to their sexual knowledge, attitudes, behaviors, and orientation. This finding could have important implications for the sexual health and well-being of MSM by suggesting that SEM-based education and intervention might hold considerable overall health potential for MSM.

    The viewing of sexually explicit media (SEM) is widespread, especially among men, and research linking SEM viewing and sexual behavior has shown a variety of results, some positive (e.g., sexuality education) and some negative (e.g., poorer body image). These results might be due to limitations in measuring SEM consumption, particularly around typology. The goal of the current study was to examine potential patterns of SEM viewing activities. Using data from an online survey of men who have sex with men (MSM), we conducted latent class analyses of 15 SEM activities. Results suggested a three-class solution. The most prevalent class included over 60% of men and was characterized by viewing primarily safer-sex or conventional behaviors. The second class included 32% of men and had a similar albeit amplified pattern of viewing. The final class included just 7% of men and was marked by high levels of viewing of all activities, including fetish and kink. Compared to the conventional or safer-sex class, the other classes had lower internalized homonegativity, lower condom use self-efficacy, and higher SEM consumption or dose. Implications for HIV prevention, sexuality research and the SEM industry are discussed. PMID:25642301

    An explicit material model that uses predicted pressure in the pores of a carbon-cloth phenolic (CCP) composite has been developed. This model is intended to be used within a finite-element model to predict phenomena specific to CCP components of solid-fuel-rocket nozzles subjected to high operating temperatures and to mechanical stresses that can be great enough to cause structural failures. Phenomena that can be predicted with the help of this model include failures of specimens in restrained-thermal-growth (RTG) tests, pocketing erosion, and ply lifting

    This study aimed to describe sexually explicit online media (SEOM) consumption among men who have sex with men (MSM) in the United States and examine associations between exposure to unprotected anal intercourse (UAI) in SEOM and engagement in both UAI and serodiscordant UAI. MSM in the U.S. who accessed a men-seeking-men website in the past year (N = 1,170) were recruited online for a cross-sectional, Internet-based survey of sexual risk and SEOM consumption. In the three months prior to interview, more than half (57%) of the men reported viewing SEOM one or more times per day and almost half (45%) reported that at least half of the SEOM they viewed portrayed UA. Compared to participants who reported that 0–24% of the SEOM they viewed showed UAI, participants who reported that 25–49%, 50–74%, or 75–100% of the SEOM they viewed portrayed UAI had progressively increasing odds of engaging in UAI and serodiscordant UAI in the past three months. As SEOM has become more ubiquitous and accessible, research should examine causal relations between SEOM consumption and sexual risk-taking among MSM as well as ways to use SEOM for HIV prevention.

    Over the past two decades, men who have sex with men (MSM) have engaged in increasing consumption of MSM-specific sexually explicit online media (i.e., online pornography). Furthermore, the amount of MSM-specific sexually explicit online media portraying unprotected anal intercourse (UAI) has increased, raising concerns about HIV transmission among the actors and the encouragement of risky sex among consumers. The influence of sexually explicit online media on sexual risk-taking, at present largely understudied, could lead to new avenues for innovative HIV prevention strategies targeting at-risk MSM. In this preliminary assessment, in-depth qualitative interviews were conducted with sixteen MSM in the Seattle area to elucidate MSM’s perceptions about the influence of sexually explicit online media on their own and other MSM’s sexual behaviors. Participants reported that sexually explicit online media: 1) plays an educational role; 2) increases comfort with sexuality; and 3) sets expectations about sexual behaviors. While participants overwhelmingly reported not feeling personally influenced by viewing UAI in sexually explicit online media, they believed viewing UAI increased sexual risk-taking among other MSM. Specifically, participants reported that the high prevalence of UAI in sexually explicit online media sends the message, at least to other MSM, that: 1) engaging in UAI is common; 2) UAI is acceptable and “ok” to engage in; and 3) future partners will desire or expect UAI. Overall, this preliminary assessment indicates that sexually explicit online media exposure may have both positive (e.g., helping MSM become more comfortable with their sexuality) and negative (e.g., normalizing UAI) impacts on the sexual health of MSM and may be useful in the development of novel HIV-prevention interventions.

    Recent research suggests that viewing sexually explicit media (SEM), i.e., adult videos, may influence sexual risk taking among men who have sex with men (MSM). Despite this evidence, very little is known about the content of gay male SEM on the Internet, including the prevalence of sexual risk behaviors and their relation to video- and performer-characteristics, viewing frequency, and favorability. The current study content analyzed 302 sexually explicit videos featuring male same-sex performers that were posted to five highly trafficked adult-oriented websites. Findings revealed that gay male SEM on the Internet features a variety of conventional and nonconventional sexual behaviors. There was a substantial prevalence of unprotected anal intercourse (UAI) (34%) and was virtually the same as the prevalence of anal sex with a condom (36%). The presence of UAI was not associated with video length, amateur production, number of video views, favorability, or website source. However, the presence of other potentially high-risk behaviors (e.g., ejaculation in the mouth, and ejaculation on/in/rubbed into the anus) was associated with longer videos, more views, and group sex videos (three or more performers). The findings of high levels of sexual risk behavior and the fact that there was virtually no difference in the prevalence of anal sex with and without a condom in gay male SEM have important implications for HIV prevention efforts, future research on the role of SEM on sexual risk taking, and public health policy.

    Despite evidence that viewing sexually explicit media (SEM) may contribute to greater numbers of sexual partners, sexual risk taking, greater interest in group sex, and lower self-esteem among men who have sex with men (MSM), research has not addressed compulsive use of Internet-based SEM due to the lack of a validated measure for this population. This report investigates the psychometric properties of the 14-item Compulsive Internet Use Scale (CIUS; Meerkerk, van den Eijnden, Vermulst, & Garretsen, 2009) adapted to assess the severity of compulsive Internet SEM use. A total of 265 Internet SEM-viewing MSM participated in an online survey about their SEM preferences, viewing habits, and recent sexual behaviors. A principal components analysis revealed a single-component, 13-item scale to adequately assess the cognitive, emotional, and behavioral aspects of this phenomenon, with a high internal consistency (α=.92). Greater compulsive use of Internet SEM was positively correlated with several relevant variables including boredom, sexual frustration, time spent viewing Internet SEM, and number of recent male sexual partners. The results offer preliminary evidence for the reliability and validity of using an adapted version of the CIUS to understand compulsive Internet SEM use, and allow for more research into the potential negative consequences of compulsive SEM use.

    This study tests the following three hypotheses: 1) there is a direct association between consumption of sexually explicit media (SEM) depicting non-condom use and STI-related sexual risk behavior among men who have sex with men (MSM), 2) The association between SEM consumption and STI-related sexual risk behavior is mediated by men’s sexual self-esteem, and 3) the relationship between SEM consumption and sexual risk behavior is mediated by condom use self-efficacy. A cross-sectional, Internet-based survey on exposure to SEM and sexual behavior of 1,391 MSM in the USA was conducted in 2011. The results confirmed hypothesis 1 and 3 while hypothesis 2 was rejected. Accordingly, a significant association between the use of SEM picturing condom use and STI related sexual risk behavior among MSM was found. Likewise, we found that the association between the use of SEM and sexual risk behavior was mediated by condom use self-efficacy in an indirect path. However, SEM did not influence sexual risk behavior via sexual self-esteem. To promote STI prevention, the actors in SEM may be used as role models in managing condom use in sexual contexts.

    Sexually explicit media may perpetuate racial and sexual norms among men who have sex with men. While men may be exposed to sexually explicit media in the online settings where they seek sex with other men, no studies to our knowledge have explored the relationship between the racial and sexual content of advertisements appearing in these spaces. In 2011, 217 sexually explicit advertisements on a male sex-seeking website were coded for themes, actor characteristics, and sexual acts depicted using a detailed codebook. Multivariable logistic regression models examined the association between skin colour, theme, sexual acts, and condomless sex acts. Nearly half (45%) featured a ‘thug’ theme (style emphasising Black masculinity/hip-hop culture), 21% featured a college theme, and 44% featured condomless sex. Ads featuring only Black men, ads featuring Black men with men of other skin tones, and ads depicting a thug theme were positively associated with depictions of condomless sex. Online sexually explicit ads featuring Black themes and actors more frequently depicted risky sex than ads with White men alone. Future research should examine whether risky depictions of Black men in online ads influence the sexual norms and cognitions of Black men who have sex with men and their partners. PMID:25891135

    The perceptual bias for sexual material has been explored mainly in normal men, and to date little attention has been paid to sexually aggressive men. The current study compared performance of sexually aggressive and nonaggressive men on experimental tasks involving sexual stimuli. Participants viewed the visual images (neutral or sexual), and, depending on the cue they were presented, they either responded to shape and color questions or just skipped to the next trial. In contrast with noncoercive men, men who admitted sexually coercive behavior showed increased response latencies only in the condition in which they were required to withdraw their attention from sexual stimuli to perform the cognitive task. Correlations with attentional performance suggested that sexually coercive men high on impulsivity and aggressiveness might experience cognitive interference when processing sexual material. These results are interpreted using disinhibition and response modulation models. PMID:21421803

    When individuals grow up with autonomy-thwarting parents, they may be prevented from exploring internally endorsed values and identities and as a result shut out aspects of the self perceived to be unacceptable. Given the stigmatization of homosexuality, individuals perceiving low autonomy support from parents may be especially motivated to conceal same-sex sexual attraction, leading to defensive processes such as reaction formation. Four studies tested a model wherein perceived parental autonomy support is associated with lower discrepancies between self-reported sexual orientation and implicit sexual orientation (assessed with a reaction time task). These indices interacted to predict anti-gay responding indicative of reaction formation. Studies 2-4 showed that an implicit/explicit discrepancy was particularly pronounced in participants who experienced their fathers as both low in autonomy support and homophobic, though results were inconsistent for mothers. Findings of Study 3 suggested contingent self-esteem as a link between parenting styles and discrepancies in sexual orientation measures. PMID:22288529

    Young people in secondary schools who are prone to engage in risky sexual behaviors spend considerable time watching Television (TV) which often presents sex scenes. The influence of exposure to sex scenes on TV (SSTV) has been little researched in Nigeria. This study was therefore designed to determine the perceived influence of exposure to SSTV on the sexual behavior of secondary school students in Ibadan North Local Government Area. A total of 489 randomly selected students were surveyed. Mean age of respondents was 14.1 ± 1.9 years and 53.8% were females. About 91% had ever been exposed to sex scenes. The type of TV program from which most respondents reported exposure to sexual scenes was movies (86.9%). Majority reported exposure to all forms of SSTV from secondary storage devices. Students whose TV watching behavior was not monitored had heavier exposures to SSTV compared with those who were. About 56.3% of females and 26.5% of males affirmed that watching SSTV had affected their sexual behavior. Predictor of sex-related activities was exposure to heavy sex scenes. Peer education and school-based programs should include topics to teach young people on how to evaluate presentations of TV programs. PMID:26099156

    The present study examined how well implicit measures were able to predict sexual orientation. Most previous research in the sexual orientation domain has been dependent upon self-report, which requires explicit, conscious awareness of sexual orientation and/or erotic preferences. On the other hand, implicit measurements are thought to be able to reflect immediate automatic reactions that may not be available to introspection. A total of 50 heterosexual and 25 homosexual men completed two implicit measures: the Implicit Association Task (IAT) and the Priming Task (PT). Sexual orientation was determined by self-report. In the PT, participants classified words as either sexually attractive or unattractive. Each word was preceded by a "prime" that was a picture of either a male or a female. The IAT consisted of classifying these same words as sexually attractive or unattractive, and classifying the pictures as either male or female. Both the IAT and the PT had very good ability to predict sexual orientation with Area Under the Curves (AUC) of 0.97 and 0.86, respectively. Unlike many other reports of implicit measures of behavior, the IAT and the PT correlated strongly with each other, and also with the explicit measurements of sexual orientation. It was concluded that these implicit measures can provide a valuable tool for research into sexual orientation and erotic preference that can complement existing measures, such as self-report questionnaires and physiological changes in sexual arousal in response to erotic stimuli.

    Although the phenomenon of hypersexuality has been described in the literature, and scales of compulsive sexual behavior have been published, the existing measures do not assess compulsive sexually explicit media (SEM) consumption. This study tested the psychometric properties of a new scale, the Compulsive Pornography Consumption (CPC). Exploratory and confirmatory factor analyses results showed good psychometric performance of a five item two factor preoccupation-compulsivity solution. As hypothesized, the scale correlates positively with compulsive sexual behavior, internalized homonegativity, and negatively with sexual self-esteem. The scale will enable researchers to investigate the etiologic factors of compulsive SEM use, and enable clinicians to assess problematic consumption. PMID:25838755

    This study sought to study consumption patterns of gay-oriented sexually explicit media (SEM) by men who have sex with men (MSM); and to investigate a hypothesized relationship between gay SEM consumption and HIV risk behavior. Participants were 1391 MSM living in the US, recruited online to complete a SEM consumption and sexual risk survey. Almost all (98.5%) reported some gay SEM exposure over the last 90 days. While 41% reported a preference to watch actors perform anal sex without condoms (termed “bareback SEM”), 17% preferred to actors perform anal sex with condoms (termed “safer sex SEM”) and 42% reported no preference. Overall SEM consumption was not associated with HIV risk; however participants who watched more bareback SEM reported significantly greater odds of engaging in risk behavior. The results suggest that a preference for bareback SEM is associated with engaging in risk behavior. More research to understand how MSM develop and maintain preferences in viewing SEM, and to identify new ways to use SEM in HIV prevention, is recommended. PMID:23564010

    HIV prevention strategies among couples include condom use, mutual monogamy, and HIV testing. Research suggests that condom use is more likely with new or casual partners, and tends to decline as relationships become steady over time. Little is known, however, about explicit mutual monogamy agreements and HIV testing within heterosexual couples. This study used data from 434 young heterosexual couples at increased risk of HIV and sexually transmitted infections (STIs) to assess (a) couple concordance on perceptions of a monogamy agreement, sustained monogamy, and HIV testing; and (b) the associations of relationship and demographic factors with monogamy agreement, sustained monogamy, and HIV testing. Results indicated only slight to fair agreement within couples on measures of monogamy agreement and sustained monogamy. Overall, 227 couples (52%) concurred that they had an explicit agreement to be monogamous; of those, 162 (71%) had sustained the agreement. Couples with greater health protective communication and commitment were more likely to have a monogamy agreement. Couples of Latino and Hispanic ethnicity and those with children were less likely to have a monogamy agreement. Only commitment was related to sustained monogamy. Having children, greater health protective communication, and perceived vulnerability to HIV and STIs were associated with HIV testing within the couple. PMID:21191869

    To inform HIV/STI prevention messaging, we used cross-sectional data from 1,231 MSM to examine the acceptability of strategies for delivering prevention messages in sexually explicit media (SEM). The majority of participants (83%) found it acceptable to include prevention messages in SEM. A latent profile analysis identified three classifications of men with similar views on the acceptability of strategies. Compared to men endorsing some strategies (54%), men endorsing all strategies (29%) were younger (PORadj=0.56 [0.39, 0.79]) and preferred viewing SEM in which the actors used condoms for anal sex (PORadj=1.53 [1.05, 2.23]). Men endorsing no strategies (17%) were of similar age to men endorsing some, but were more likely to prefer viewing SEM in which the actors did not use condoms (PORadj=2.44 [1.43, 4.16]) and to report engaging in insertive unprotected anal sex within the last 3 months (PORadj=2.03 [1.11, 3.70]). Opportunities exist to use SEM for HIV/STI prevention. PMID:23837809

    To assess problematic sexually explicit media (SEM) consumption, and to identify clinically meaningful cut-off points, we examined clinical correlates using the new Compulsive Pornography Consumption (CPC) scale among 1165 participating MSM. Building on scale practices in measuring compulsive sexual behavior, two cut-off points were identified. While most (76-80%) MSM do not report compulsive symptoms, about 16-20% report levels of problematic SEM consumption, including 7% with extreme scores consistent with DSM criteria for compulsive disorders. Demographic, sexual, and HIV risk differences were identified between the three groups. Researchers and clinicians are encouraged to consider using the CPC scale for comprehensive assessment of compulsive sexual behavior. PMID:26167109

    As part of an ongoing research project we examined information-processing biases in forensic and nonforensic participants (n = 10 sex offenders, n = 10 violent offenders, n = 10 nonviolent offenders, and n = 13 undergraduates). A computerised version of the Stroop task demonstrated that offenders convicted of both sexual and violent offences were significantly slower than undergraduates to color-name words relating to sexual offending (with sex offenders demonstrating the greatest interference bias). Furthermore, processing bias was also evident for aggression words in violent offenders and violent sexual offenders but not in non-violent sexual offenders. Specifically, paedophiles convicted of indecent assault presented different response profiles compared to heterosexual rapists. These findings suggest that tests that assess information processing bias for salient material may also prove useful as an assessment tool within forensic populations. PMID:15208900

  4. Explicit jump immersed interface method for virtual material design of the effective elastic moduli of composite materials

    2006-12-01

    Virtual material design is the microscopic variation of materials in the computer, followed by the numerical evaluation of the effect of this variation on the material?s macroscopic properties. The goal of this procedure is an in some sense improved material. Here, we give examples regarding the dependence of the effective elastic moduli of a composite material on the geometry of the shape of an inclusion. A new approach on how to solve such interface problems avoids mesh generation and gives second order accurate results even in the vicinity of the interface. The Explicit Jump Immersed Interface Method is a finite difference method for elliptic partial differential equations that works on an equidistant Cartesian grid in spite of non-grid aligned discontinuities in equation parameters and solution. Near discontinuities, the standard finite difference approximations are modified by adding correction terms that involve jumps in the function and its derivatives. This work derives the correction terms for two dimensional linear elasticity with piecewise constant coefficients, i.e. for composite materials. It demonstrates numerically convergence and approximation properties of the method.

    The objective of this study was to identify the knowledge about sexuality (including STD/HIV/AIDS), the sexual practices more frequents and sexuality education sources in a group of students with visual impairments. A self administered questionnaire was utilized in 50 students with visual impairment. Descriptive statistics were utilized. Seventy six percent (76.0%) of the participants presented a high knowledge about sexuality and 22.0% presented moderated knowledge. The no penetrative sexual practice more frequent was corporal caress (82.0%) and the penetrative was penis-vagina (74.0%). The source of sexuality education most common was the conferences (83.9%). Although, in general, the knowledge about sexuality was high, there are "gaps" in them. There is the need to develop educational materials adapted to the needs of the studied population.

    Although compulsive sexual behaviour (CSB) has been conceptualized as a "behavioural" addiction and common or overlapping neural circuits may govern the processing of natural and drug rewards, little is known regarding the responses to sexually explicit materials in individuals with and without CSB. Here, the processing of cues of varying sexual content was assessed in individuals with and without CSB, focusing on neural regions identified in prior studies of drug-cue reactivity. 19 CSB subjects and 19 healthy volunteers were assessed using functional MRI comparing sexually explicit videos with non-sexual exciting videos. Ratings of sexual desire and liking were obtained. Relative to healthy volunteers, CSB subjects had greater desire but similar liking scores in response to the sexually explicit videos. Exposure to sexually explicit cues in CSB compared to non-CSB subjects was associated with activation of the dorsal anterior cingulate, ventral striatum and amygdala. Functional connectivity of the dorsal anterior cingulate-ventral striatum-amygdala network was associated with subjective sexual desire (but not liking) to a greater degree in CSB relative to non-CSB subjects. The dissociation between desire or wanting and liking is consistent with theories of incentive motivation underlying CSB as in drug addictions. Neural differences in the processing of sexual-cue reactivity were identified in CSB subjects in regions previously implicated in drug-cue reactivity studies. The greater engagement of corticostriatal limbic circuitry in CSB following exposure to sexual cues suggests neural mechanisms underlying CSB and potential biological targets for interventions.

    Use of sexual material online (USMO) by young people has been connected with at-risk sexual behavior for HIV/AIDS. Media Richness and Social Cognitive theories propose that rich media offer more information with interactive and audible visual content, which could have a significant impact on people’s thinking and behavior. The objective was to determine whether USMO presented by rich media has an influence on at-risk sexual behavior for HIV/AIDS. Two hundred young people participated in the study, and it was found that USMO from rich media is connected to at risk sexual behavior for HIV/AIDS (p<.01). Young people who use rich media for masturbation (F[2,189]=10.169, p<.001), arousal (F[2,189]=4.686, p<.05), stimulation (F[2,189]=8.382, p<.001), and seeking adventures (F[2,189]=6.406, p<.01) were more likely to show at risk sexual behavior for HIV/AIDS. The study also found that young people may experience pleasure from USMO in rich media and feel motivated to model what they observe. PMID:24199040

    2012-01-01

    Sexual violence against women is a major concern to researchers and policy makers, as well as to the general public. This study uses a sample of more than 2,000 college students to investigate the extent to which exposure to harsh parenting practices and sexually explicit materials contributes to perpetration and victimization. Findings indicate that frequent corporal punishment in the family of origin combined with consumption of pornographic materials increased the probability that males reported engaging in coercive sexual practices. For females, both frequent corporal punishment and exposure to paternal hostility combined with consumption of pornographic materials were associated with higher levels of reported sexual victimization. These results provide increased understanding of the impact of pornography use among a nonclinical sample, as well as the consequences of experiencing harsh corporal punishment in one's family of origin, on the sexual victimization of females.

    2015-04-01

    We trace the history of the phallometric test--which measures erections of men exposed to visual erotic stimuli to characterize sexualities--in order to account for its functioning as a 'truthing technology'. On the basis of a content analysis of 410 key scientific journal article abstracts, we argue that since its invention in Czechoslovakia in the 1950s, phallometry has been employed within three distinct assemblages: as a test of predominance of sexual desire, as a test for therapeutic efficacy, and as a threshold test of sexual risk. Drawing on works of theorists of materialization and proponents of script theory, we argue that within each assemblage phallometric testing materializes male desire and renders it measurable via a 'technosexual script'. We consider the performative effects of phallometry in establishing scientific conceptions of normal and abnormal sexualities. At the same time, through attention to debates among practitioners and broader controversies surrounding the employment of phallometry, we examine the limits of researchers' abilities to establish the broader credibility of the test and capture the phenomenon of sexual desire. This analysis contributes to the study of truthing technologies (or 'truth machines') as a class, while also helping to build bridges between science and technology studies and sexuality studies.

    The objective of the present study was to search for the methods for the enhancement of the effectiveness of forensic medical examination of material evidence during the investigations into the crimes against sexual immunity and personal sexual freedom. The work included the analysis of the relevant expert conclusions and copies of the decisions approving the performance of the forensic medical expertises. The study was carried out with the use of the following methods: the extraction of necessary data from the primary materials, their systematization and treatment by the methods of descriptive and analytical statistics. The study has demonstrated significant differences in the frequency of discovery of biological evidence of sexual offence depending on the character of the objects available for the examination and the time of their obtaining; these parameters were shown to depend on a variety of factors. It is concluded that the multidisciplinary approach to the selection and examination of material evidence for the purpose of the investigation into the cases of sexual offence makes it possible to considerably enhance the effectiveness of forensic medical expertises for the search of biological evidence of sexual crimes and thereby to improve the quality of this work.

    2010-02-01

    In spite of a growing presence of pornography in contemporary life, little is known about its potential effects on young people's sexual socialization and sexual satisfaction. In this article, we present a theoretical model of the effects of sexually explicit materials (SEM) mediated by sexual scripting and moderated by the type of SEM used. An on-line survey dataset that included 650 young Croatian men aged 18-25 years was used to explore empirically the model. Descriptive findings pointed to significant differences between mainstream and paraphilic SEM users in frequency of SEM use at the age of 14, current SEM use, frequency of masturbation, sexual boredom, acceptance of sex myths, and sexual compulsiveness. In testing the model, a novel instrument was used, the Sexual Scripts Overlap Scale, designed to measure the influence of SEM on sexual socialization. Structural equation analyses suggested that negative effects of early exposure to SEM on young men's sexual satisfaction, albeit small, could be stronger than positive effects. Both positive and negative effects-the latter being expressed through suppression of intimacy-were observed only among users of paraphilic SEM. No effect of early exposure to SEM was found among the mainstream SEM users. To counterbalance moral panic but also glamorization of pornography, sex education programs should incorporate contents that would increase media literacy and assist young people in critical interpretation of pornographic imagery.

  5. Challenging Pentecostal moralism: erotic geographies, religion and sexual practices among township youth in Cape Town.

    2011-06-01

    Research on constructions of sexuality in Pentecostalism often struggles with the fact that the research setting is defined ex ante in terms of church communities, which imposes upon ethnographic accounts the same limitations Pentecostal morality imposes upon church members' discourse. Taking young Pentecostals operating in a space that is not explicitly religious as the methodological entrance to the field, this paper explores negotiations over sexuality, intimate relationships and love among Xhosa-speaking township youth. It introduces the notion of erotic geographies to consider how possible influences of religious discourses on sexuality are refracted by alternative cultural orientations and material contexts. Findings suggest that premarital abstinence appears as a highly exceptional ideal for youth. Even among Pentecostal youth, notions of sexuality are largely severed from religiosity and faithfulness and romanticism are dominant ideals. Future research on Pentecostalism and sexuality should be less religious-centric and rooted more firmly in ethnographies of youth sexual cultures. PMID:21462006

    Somnambulism or sleepwalking is a viable defence on the basis of automatism. The behaviours that occur during sleepwalking can be highly complex and include sexual behaviour of all types. Somnambulistic sexual behaviour (also called sexsomnia, sleep sex) is considered a variant of sleepwalking disorder as the overwhelming majority of people with Sexsomnia have a history of parasomnia and a family history of sleepwalking. Sexual behaviour during a sleep automatism can vary from explicit sexual vocalisations, to violent masturbation, to complex sexual acts including anal, oral and vaginal penetration. A recent case in England is reported where the defendant was acquitted on 3 charges of rape on the basis of automatism due to somnambulistic sexual behaviour. PMID:16564199

    2016-01-01

    The Internet provides a large source of novel and rewarding stimuli, particularly with respect to sexually explicit materials. Novelty-seeking and cue-conditioning are fundamental processes underlying preference and approach behaviors implicated in disorders of addiction. Here we examine these processes in individuals with compulsive sexual behaviors (CSB), hypothesizing a greater preference for sexual novelty and stimuli conditioned to sexual rewards relative to healthy volunteers. Twenty-two CSB males and forty age-matched male volunteers were tested in two separate behavioral tasks focusing on preferences for novelty and conditioned stimuli. Twenty subjects from each group were also assessed in a third conditioning and extinction task using functional magnetic resonance imaging. CSB was associated with enhanced novelty preference for sexual, as compared to control images, and a generalized preference for cues conditioned to sexual and monetary versus neutral outcomes compared to healthy volunteers. CSB individuals also had greater dorsal cingulate habituation to repeated sexual versus monetary images with the degree of habituation correlating with enhanced preference for sexual novelty. Approach behaviors to sexually conditioned cues dissociable from novelty preference were associated with an early attentional bias to sexual images. This study shows that CSB individuals have a dysfunctional enhanced preference for sexual novelty possibly mediated by greater cingulate habituation along with a generalized enhancement of conditioning to rewards. We further emphasize a dissociable role for cue-conditioning and novelty preference on the early attentional bias for sexual cues. These findings have wider relevance as the Internet provides a broad range of novel and potentially rewarding stimuli. PMID:26606725

    The Internet provides a large source of novel and rewarding stimuli, particularly with respect to sexually explicit materials. Novelty-seeking and cue-conditioning are fundamental processes underlying preference and approach behaviors implicated in disorders of addiction. Here we examine these processes in individuals with compulsive sexual behaviors (CSB), hypothesizing a greater preference for sexual novelty and stimuli conditioned to sexual rewards relative to healthy volunteers. Twenty-two CSB males and forty age-matched male volunteers were tested in two separate behavioral tasks focusing on preferences for novelty and conditioned stimuli. Twenty subjects from each group were also assessed in a third conditioning and extinction task using functional magnetic resonance imaging. CSB was associated with enhanced novelty preference for sexual, as compared to control images, and a generalized preference for cues conditioned to sexual and monetary versus neutral outcomes compared to healthy volunteers. CSB individuals also had greater dorsal cingulate habituation to repeated sexual versus monetary images with the degree of habituation correlating with enhanced preference for sexual novelty. Approach behaviors to sexually conditioned cues dissociable from novelty preference were associated with an early attentional bias to sexual images. This study shows that CSB individuals have a dysfunctional enhanced preference for sexual novelty possibly mediated by greater cingulate habituation along with a generalized enhancement of conditioning to rewards. We further emphasize a dissociable role for cue-conditioning and novelty preference on the early attentional bias for sexual cues. These findings have wider relevance as the Internet provides a broad range of novel and potentially rewarding stimuli. PMID:26606725

    Metals can in theory be infinitely recycled in a closed-loop without any degradation in quality. In reality, however, open-loop recycling is more typical for metal scrap recovered from end-of-life (EoL) products because mixing of different metal species results in scrap quality that no longer matches the originals. Further losses occur when meeting the quality requirement of the target product requires dilution of the secondary material by adding high purity materials. Standard LCA usually does not address these losses. This paper presents a novel approach to quantifying quality- and dilution losses, by means of hybrid input-output analysis. We focus on the losses associated with the recycling of ferrous materials from end-of-life vehicle (ELV) due to the mixing of copper, a typical contaminant in steel recycling. Given the quality of scrap in terms of copper density, the model determines the ratio by which scrap needs to be diluted in an electric arc furnace (EAF), and the amount of demand for EAF steel including those quantities needed for dilution. Application to a high-resolution Japanese IO table supplemented with data on ferrous materials including different grades of scrap indicates that a nationwide avoidance of these losses could result in a significant reduction of CO(2) emissions.

    A team consisting of Arizona State University, Honeywell Engines, Systems & Services, the National Aeronautics and Space Administration Glenn Research Center, and SRI International collaborated to develop computational models and verification testing for designing and evaluating turbine engine fan blade fabric containment structures. This research was conducted under the Federal Aviation Administration Airworthiness Assurance Center of Excellence and was sponsored by the Aircraft Catastrophic Failure Prevention Program. The research was directed toward improving the modeling of a turbine engine fabric containment structure for an engine blade-out containment demonstration test required for certification of aircraft engines. The research conducted in Phase II began a new level of capability to design and develop fan blade containment systems for turbine engines. Significant progress was made in three areas: (1) further development of the ballistic fabric model to increase confidence and robustness in the material models for the Kevlar(TradeName) and Zylon(TradeName) material models developed in Phase I, (2) the capability was improved for finite element modeling of multiple layers of fabric using multiple layers of shell elements, and (3) large-scale simulations were performed. This report concentrates on the material model development and simulations of the impact tests.

  15. The Explicit Method

    NASA Astrophysics Data System (ADS)

    Britz, Dieter

    The simplest method of simulating for pdes, and in particular for odes, is the Euler method, in the present context usually called the [explicit method], or EX hereafter. It has many drawbacks (to be outlined) but it does have the advantage of simplicity of programming and if you are willing to let your computer do the hard work, it can yield adequate results in many cases. There are recent examples of the use of the method even for rather complex systems [324, 349] and a textbook on cyclic voltammetry [274] advocates the method (and provides a program in Pascal). One might thus choose the method as such, or choose to use it as a learning tool. The present author prefers the latter. Having learned how to use EX and aware of its drawbacks, one might be ready to learn something more advanced.

    We report our observation that radiation from a system of accelerating charges is possible only when there is explicit breaking of symmetry in the electric field in space within the spatial configuration of the radiating system. Under symmetry breaking, current within an enclosed area around the radiating structure is not conserved at a certain instant of time resulting in radiation in free space. Electromagnetic radiation from dielectric and piezoelectric material based resonators are discussed in this context. Finally, it is argued that symmetry of a resonator of any form can be explicitly broken to create a radiating antenna.

    Time integration methods can be separated into two groups: explicit and implicit. Methods which do not involve the solution of any algebraic equations are called explicit, while those that require the solution of equations are called implicit. The relative advantages and disadvantages of explicit and implicit methods are summarized. The major trend in the past decade of research was to use hybrization methods to take advantage of the complementary nature of the positive attributes of explicit and implicit integration. These trends are briefly discussed.

    Research on the role of sex-related Internet use in adolescents' sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents' lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents' experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (M(age) T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents' perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents' level of experience with sexual behavior at the end of the study. Boys' SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents' sexual health. PMID:26086606

    Existing studies of the sexual content of television programming and advertising and the effects of this content on adolescent viewers are reviewed. Content studies show that the frequency of sexual references have increased in the past decade and are increasingly explicit. Studies of the effects of this content, while scarce, suggest that adolescents who rely heavily on television for information about sexuality will have high standards of female beauty and will believe that premarital and extramarital intercourse with multiple partners is acceptable. They are unlikely to learn about the need for contraceptives as a form of protection against pregnancy or disease. Suggestions for future research and trends in television programming policies are explored. PMID:2307597

    1990-05-01

    To replicate and explore the associations of drawing genitalia on a human figure, child-rearing practices, and a history of alleged sexual abuse, we designed a cross-sectional study of 109 alleged child sexual abuse victims, ages 3 through 8 years, and a group of 109 comparison children matched for age, sex, race, and socioeconomic status but with no history of abuse. A standardized format was used to collect drawings, administer the Peabody Picture Vocabulary Test, and gather background data on medical, developmental, and child-rearing issues. Seven alleged sexual abuse victims and one comparison child spontaneously drew genitalia (p = 0.02, one-tailed Fisher Exact Test, estimated relative risk 7.96). No differences in drawing maturity (Draw-A-Man score) were identified, although Peabody Picture Vocabulary Test scores were higher in comparison children (82.1 vs. 91.0, p less than 0.01). Neither drawing genitalia nor history of alleged sexual abuse were significantly associated with histories of medical problems, enuresis, encopresis, urinary tract infection, or child-rearing practices related to sleeping, nudity, bathing, sexual abuse education, or exposure to sexually explicit materials. The similar patterns of child-rearing practices in both samples should make professionals cautious in attributing allegations of abuse to specific child-rearing practices. This study confirms our previous report that the presence of genitalia spontaneously drawn on a child's drawing of a human figure is associated with alleged sexual abuse. PMID:2329432

    Introduction The influence of media portrayals of sexual attitudes and normative expectations of young people at a critical developmental stage is of public health concern. Objectives To examine the role of mass media and Internet utilization in shaping the sexual health attitudes and behaviors of young undergraduates in Osogbo metropolis, Osun State, Nigeria. Materials and methods In a descriptive cross-sectional study, 400 undergraduates were selected using a multistage random sampling technique. Four hundred and fifty pretested, semistructured questionnaires were distributed; of these, 400 were returned properly filled. Data were analyzed using SPSS statistical software version 16. Results Mean age of respondents ± standard deviation was 23.6±2.99 years. Most were aware of the various forms of mass media (>95%). Most (64.0%) respondents spent 1–5 hours watching television, daily, and most used the Internet often. About 38.3% and 24.2% of respondents used the Internet and radio/television, respectively, as sources of information on sexual issues. Most respondents used the Internet for school assignments (83.0%, n=332), electronic mail (89.0%, n=356), and for accessing sexually explicit materials (74.5%, n=298). Most of the respondents (73.5%) opined that the Internet has a bad influence on youths’ sexual behavior, although accessing the Internet for sexual material or movies was acceptable to 25.3% of them. Of the 226 respondents who had ever had sex, 226 (100%), 37 (16.4%), 31 (13.7%), and 10 (4.4%) practiced coitus, oral sex, masturbation, and anal sex, respectively; 122 (54.0%) always used condoms, whereas 90 (40.0%) never used condoms during sexual activity; 33 (14.6%) had had sex with commercial sex workers. Further analysis showed that those who were yet to marry (single) were less likely to be sexually experienced than those who were married (adjusted odds ratio [AOR] =0.075, 95% confidence interval [CI] =0.008–0.679), and those who said accessing the Internet for sexual material is not acceptable to them were also less likely to be sexually experienced than those to whom it was acceptable (AOR =0.043, 95% CI =0.016–0.122). Predictors of having multiple sexual partners include the sex of the respondent and the frequency of Internet use, with females (AOR =0.308, 95% CI =0.113–0.843) and those who rarely use the Internet less likely to have multiple sexual partners. Conclusion We conclude that uncontrolled exposure to mass media and Internet could negatively influence the sexual patterns and behavior of youths. PMID:24729737

It is much easier to retrieve remote, explicit memories, such as events (eg, a party where balloons popped) or playing with objects, than to recall the process of sexual development with no distinct markers in the individual's history. Because these distinct experiences predated identified sexuality, became a focus of attention for the individual, and then were incorporated into the individual's sexual interests and masturbatory fantasies, it was possible to accurately track the patterns of sexual arousal. We were also able to clearly identify how these men attempted to blend their deviant interests into sexual relationships with partners and the consequences of their efforts. If we are to understand how sexual interests develop, a number of obstacles need to be overcome. Sexual interest has to be openly discussed. Parents need to appreciate how the early sexual interests of their children can go awry, contaminate their adult relationships, and lead to problematic lives. Researchers need a means of understanding how to communicate with children about their earliest interests, sexual interests, and sexual behaviors in a nonjudgmental manner. Until then, tracking unusual interests that lead to erotic interests is the first step in the overall process of understanding how sexual interest develops and is assimilated, either successfully or unsuccessfully, into an individual's adult sexual life.

    The Willmore surfaces provide local extrema to the so-called Willmore functional, which assigns to each surface its total squared mean curvature. There is a special class of axially symmetric Willmore surfaces whose profile curves satisfy a relatively simpler system of ordinary differential equations. The aim of this work is to give explicit parametrizations of the Willmore surfaces belonging to the foregoing family in terms of the Jacobian elliptic functions and elliptic integrals.

    To aid risk assessment, management, and treatment planning it is essential to assess child sexual abusers' deviant sexual interests (DSI) and preferences (DSP) for sex with children. However, measurement of DSI/DSP is fraught with psychometric problems. In consequence, research interest has shifted to latency-based indirect measures as a measurement approach to complement self-report and physiological assessment. Utilizing the Explicit and Implicit Sexual Interest Profile (EISIP)-a multimethod approach consisting of self-report, viewing time, and Implicit Association Test (IAT) DSI/DSP measures-we replicated phallometric DSI/DSP differences between child sexual abuser subgroups in a sample of intrafamilial, extrafamilial, and child pornography offenders. DSI/DSP was associated with recidivism risk, offense-behavioral measures of pedophilic interest, and sexual fantasizing. It also negatively correlated with antisociality. Distinguishing between child sexual abuser subtypes and being related to recidivism risk, the EISIP is a useful tool for sexual offender assessments. PMID:23524323

    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

    The following explicit model, valid for high aperture refraction with homogenous and isotropic materials, encompasses all explicit solutions of the first-order nonlinear differential equation representing the perfect image-forming process of any axial object point into its axial image point. Solutions include well-known cases, such as flats, spheres, prolate ellipsoids, prolate hyperboloids, and other sections of nondegenerate Cartesian ovals of revolution, now classified according to the recurrent explicit solution introduced herein. We also present some series expansions, given in cylindrical coordinates z(r), for more efficient computation. Explicit solutions allow accurate and expedite thickness calculation as compared to the regular series, parametric, or implicit solutions commonly used. The results of this study are useful in the design of centered optical systems that are perfectly aligned. PMID:24323263

    2014-04-01

    The author reconsiders Freud's "The Sexual Aberrations," the first of his Three Essays on the Theory of Sexuality (1905), in light of contemporary psychoanalytic theory. Are the concepts of sexual aberration and norm still viable? The author argues that they are necessary but insufficient elements in current theory. He then presents a competing model in which sexuality can be reduced to a more elemental level of disturbance and wish, where it is an expression of a nonsexual wish--for example, to possess or control the object to eliminate separateness. The author presents clinical material to demonstrate this alternative model. PMID:24777366

    Emens, Elizabeth F

    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. PMID:24654293

  2. Adolescent sexuality.

    The consequences of adolescent sexual behavior are an enormous burden both for the adolescent and society. The problem is not that teens are sexually active but rather that they have little preparation and guidance in developing responsible sexual behavior. Developmentally, adolescents reach physical maturity before they are cognitively able to appreciate the consequences of their behavior. A teenager's primary source of information regarding sexuality is his or her peer group, all of whom are experiencing and reinforcing the same behaviors. The family, the major socializer of other behaviors, is not as powerful a force in shaping responsible sexual behavior because of parental discomfort with sex education and sexual discussions. This is the result of a social milieu in which sex is frequently portrayed but rarely linked with responsible behavior or accurate, nonjudgmental information. The pediatric practitioner is in an ideal position to intervene in these dynamics. In the office, the practitioner can provide accurate sexual information to both parents and adolescents, support parental-child communication on sexual issues, and provide appropriate services or referral. In the community, the practitioner can advocate for school-based sex education as well as act as an information resource. Finally, the practitioner can advocate for the health care needs for adolescents on a national level, supporting legislation that provides adolescents with information and access to services necessary to make responsible sexual decisions.

  3. Internet Sexualities

    NASA Astrophysics Data System (ADS)

    Döring, Nicola

    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.”

    The present study evaluated and compared the effects of experimentally adopted sexual schemas on vaginal response, subjective sexual arousal, and affect in 17 women with Female Sexual Arousal Disorder (FSAD) and 17 sexually healthy women. Positive and negative cognitive schemas were presented to participants before viewing sexually explicit video segments. They were asked to temporarily adopt both schemas, and vaginal response, subjective sexual arousal, and affect were measured in each schema condition. Participants in both groups had significantly greater vaginal response and reported more subjective sexual arousal in the positive schema condition than in the negative schema condition. Sexually healthy women demonstrated significantly higher subjective sexual arousal than women with FSAD, but there were no significant group differences in vaginal response. Moreover, participants in both groups reported higher levels of Positive Affect and Vigor in the positive schema condition than in the negative schema condition but higher levels of Negative Affect, Tension-Anxiety, and Anger-Hostility in the negative schema condition than in the positive schema condition. These findings demonstrate the impact of cognitions on sexual arousal, which has important implications for addressing cognitions in the treatment of FSAD. Moreover, these findings have implications for the conceptualization of FSAD, which may be best characterized as a complex, heterogeneous cluster of symptoms. PMID:18256919

    Sexual arousal has emerged as an important contextual feature in sexual encounters that can impact safer-sex decision-making. We conducted two experiments that investigated the effects of sexual arousal among male and female participants. Experiment 1 (N = 144) examined the impact of sexual around on sexual health decision-making. Sexually explicit and neutral video clips as well as hypothetical romantic scenarios were used to evaluate the effects of sexual arousal on sexual risk-taking intentions. Men and women who reported higher levels of sexual arousal also displayed greater intentions to participate in risky sexual behavior (e.g., unprotected sex with a new sex partner). Experiment 2 (N = 122) examined the impact of sexual arousal on general risk-taking, using the same videos clips as in Experiment 1 and a modified version of a computerized Blackjack card game. Participants were offered a chance to make either a risky play or a safe play during ambiguous conditions. Increased sexual arousal in Experiment 2 was associated with impulsivity and a greater willingness to make risky plays in the Blackjack game. These findings suggest that, in situations where there are strong sexually visceral cues, both men and women experiencing strong sexual arousal may have lower inhibitions and may experience impaired decision-making. This phenomenon may have an impact during sexual encounters and may contribute to a failure to use appropriate prophylactic protection. PMID:26310879

    2008-06-01

    In contemporary Vietnam, young, unmarried, educated women are struggling to negotiate the contradictory expectations of femininity. Qualitative research conducted in Hanoi with 13 unmarried, educated women, aged from 25 to 34 years, explored women's sexual agency in a context of changing discourses on sexuality and gender roles. Interviews were conducted several times with each woman to enable in-depth understanding of sexual experiences and meanings. Either implicitly or explicitly, women in the research were found to resist the power of public discourses on femininity and sexuality. Notions of femininity can be interpreted as a temporary means for women to gain control over sexual relationships. It is crucial to acknowledge the sexual agency of unmarried, educated women and its diverse forms in order to understand complex sexual behaviours and to promote their sexual rights and health.

  20. Sexuality education in Russia: defining pleasure and danger for a fledgling democratic society.

    PubMed

    Rivkin-Fish, M

    1999-09-01

    Public health indicators have plummeted throughout Russia since the collapse of the Soviet Union, with exponential increases in sexually transmitted diseases reported among this society's young adults. Newly developing sexuality education programs provide insights into the ways local health providers interpret such public health challenges and conceptualize the educational needs of Russian youth. Moreover, these initiatives reveal the impact of both Soviet-era discourses and more recent, international anti-abortion activism on contemporary thinking about sexual health matters. This article explores the implicit and sometimes explicit ways that sex education lectures are being driven by debates over the significance of the Soviet past and anxieties over the perceived chaos of current transformations. Drawing on material from lectures, fieldwork, and interviews with sex educators, I argue that sexuality education efforts reveal a persistent ambivalence between the hope to promote individual autonomy from state interests and the presumed need to control sexual expression and reproductive practices within an emerging moral economy of post-Soviet Russia.

    1997-04-01

    This study examines the potential harm of sexually explicit and/or violent films to women viewers. More specifically, it investigates the idea that the visual media contribute to a cultural climate that is supportive of attitudes facilitating violence against women, diminish concern for female victims (desensitization), and have a negative impact on women's views of themselves. In this study, women viewed 1 film per day for 4 consecutive days from one of these 3 categories: 1) sexually explicit but nonviolent; 2) sexually explicit, sexually violent; and 3) mildly sexually explicit, graphically violent. They then served as jurors in a simulated rape trial. The study found that exposure to both types of violent stimuli produced desensitization and ratings of the stimuli as less degrading to women. Moreover, women exposed to the mildly sexually explicit, graphically violent images were less sensitive toward the victim in the rape trial compared with the other film viewers. However, no differences were found between the film groups and the no-exposure control group with regard to women¿s self-perception. PMID:12294812

    Three studies offer novel evidence addressing the consequences of explicit–implicit sexual orientation (SO) ambivalence. In Study 1, self-identified straight females completed explicit and implicit measures of SO. The results revealed that participants with greater SO ambivalence took longer responding to explicit questions about their sexual preferences, an effect moderated by the direction of ambivalence. Study 2 replicated this effect using a different paradigm. Study 3 included self-identified straight and gay female and male participants; participants completed explicit and implicit measures of SO, plus measures of self-esteem and affect regarding their SO. Among straight participants, the response time results replicated the findings of Studies 1 and 2. Among gay participants, trends suggested that SO ambivalence influenced time spent deliberating on explicit questions relevant to sexuality, but in a different way. Furthermore, the amount and direction of SO ambivalence was related to self-esteem. PMID:24972940

    PubMed

    Thomas, Lindsey A; Gorzalka, Boris B

    2012-08-01

    Fifty-nine heterosexual university males were assessed for Sexual Coercion Proclivity (SCP) and randomly assigned to one of three conditions: Insult/nonsexually coercive fantasy material; no insult/sexually coercive fantasy material; or, insult/sexually coercive fantasy material. Although not differing in terms of anger or anxiety, the high SCP became more frustrated than the low group, particularly when exposed to both insult and sexually coercive (SC) fantasy material. Changes in negative affect predicted anticipated likelihood of engaging in SC among the low SCP group and anticipated enjoyment of SC in the high SCP group. Acculturation accounted for differences observed between Caucasian and Chinese men. PMID:22892359

  14. Opioid mediation of learned sexual behavior

    PubMed Central

    Holloway, Kevin S.

    2012-01-01

    Identifying the role of opioids in the mediation of learned sexual behaviors has been complicated by the use of differing methodologies in the investigations. In this review addressing multiple species, techniques, and pharmaceutical manipulations, several features of opioid mediation become apparent. Opioids are differentially involved in conditioned and unconditioned sexual behaviors. The timing of the delivery of a sexual reinforcer during conditioning trials, especially those using male subjects, acutely influences the role that opioids have in learning. Opioids may be particularly important in the maintenance of conditioned sexual behaviors during periods of non-reinforcement. This appears to be true both for probe trials and procedures designed explicitly to extinguish a sexual conditioned response. These features of opioid mediation of learning do not appear to be restricted to sexual conditioning paradigms. This suggests that, as for other aspects of sexual learning that despite distinctive features conform to underlying behavioral principles, the mediation of conditioned sexual behavior by opioids relies on processes common across reinforcement systems.

That fusion can be observed in private circumstances as well as in society at large. Children and young people as well as women and men can fall victim to that phenomenon. Eventually, due to gender stereotyping, the awareness of the victimization of the male gender is somewhat weak. In the social-political discourse the male is seen as dominant and powerful and the female gender as the weak one. Sexual violence and/or domination therefore is interpreted as mirroring the genderized balance of power in society. Otherwise the phenomenon is very complex and cannot be explained by simplistic or one-dimensional interpretations. In respect of definitions it is necessary to separate "sexual violence", as an aspect of sexual behavior, and "sexualized power". The latter means the use of sexuality for the display of power and violence. That kind of fusion is visible in all kinds of interactions--on the private level as well as in the sense of "structural power" (like in war, torture, etc.). To theory and practice of psychiatry and psychotherapy the situation brings a whole series of objectives. On the one hand these disciplines have the task to study the phenomenon in different contexts and to contribute to the understanding of the psychic and psychosocial processes which lead to the fusion of the drives. On the other hand it is their obligation to treat the victims of sexual trauma. In recent times much insight has been gained in that context. Nevertheless there has to be much future work done, to understand the phenomenon more deeply and to develop adapted and efficient concepts for prevention and treatment. PMID:16392425

    2001-01-01

    Early sexual intercourse among American adolescents represents a major public health problem. Although early sexual activity may be caused by a variety of factors, the media are believed to play a significant role. In film, television, and music, sexual messages are becoming more explicit in dialogue, lyrics, and behavior. In addition, these messages contain unrealistic, inaccurate, and misleading information that young people accept as fact. Teens rank the media second only to school sex education programs as a leading source of information about sex. Recommendations are presented to help pediatricians address the effects of the media on sexual attitudes, beliefs, and behaviors of their patients. PMID:11134460

    Sexual information seeking is an important element within human information behavior. Seeking sexually related information on the Internet takes many forms and channels, including chat rooms discussions, accessing Websites or searching Web search engines for sexual materials. The study of sexual Web queries provides insight into sexually-related information-seeking behavior, of value to Web users and providers alike. We qualitatively analyzed queries from logs of 1,025,910 Alta Vista and AlltheWeb.com Web user queries from 2001. We compared the differences in sexually-related Web searching between Alta Vista and AlltheWeb.com users. Differences were found in session duration, query outcomes, and search term choices. Implications of the findings for sexual information seeking are discussed. PMID:15006171

    2010-01-01

    The present study was conducted in an attempt to examine potential differences between men and women in memory for sexually relevant information. A total of 77 undergraduate students (31 men, 46 women) read a sexual story and completed memory tasks in response to the story. Based on previous research, we hypothesized that differences would exist between men and women for different types of sexual information and we hoped to understand whether specific variables (sexual experiences, sexual functioning, and reactions to the sexual story) could explain such differences. Men were more likely to remember erotic or explicit details of the story, whereas women were more likely to remember love and emotional bonding details of the story. Additionally, women were more likely to recall information referencing the characters in the story. Results from regression analyses indicated that sexual desire and satisfaction were related to differences in recall and recognition of the love and emotional bonding aspects of the story, and that frequency of sexual intercourse was related to differences in the recall of erotic or explicit details of the story. The significant results obtained in this study correspond to previously established sex differences in memory for sexual information. PMID:17186127

    2015-01-01

    Public reactions to internet child offending remain ambivalent in that, while there is vocal condemnation of contact child sex offending, there is less indignation about internet child abuse. This is potentially due to a lack of recognition of this type of offence as sexual offending per se. This ambiguity is reflected by internet sex offenders themselves in their verbalizations of their offending. This article presents a qualitative analysis of the accounts offered by seven individuals convicted of internet-based sexual offences involving the downloading and viewing of images of children. In particular, this article presents an analysis of the explanations of offenders for the commencement of internet activity and the progression to more illicit online materials. The data were collected through semi-structured interviews and analyzed using discursive methods, paying close attention to language use and function. The analysis documented the practices that internet child abusers employed in order to manage their identities, distance themselves from the label of sex offender, and/or reduce their personal agency and accountability. Implications of this analysis are discussed with reference to the current minimization of the downloading of sexually explicit images of children as a sexual crime per se by the public and offenders alike and the risk assessment and treatment of individuals convicted of these offences.

  5. Sexual selection: Another Darwinian process.

    Why was sexual selection so important to Darwin? And why was it de-emphasized by almost all of Darwin's followers until the second half of the 20th century? These two questions shed light on the complexity of the scientific tradition named "Darwinism". Darwin's interest in sexual selection was almost as old as his discovery of the principle of natural selection. From the beginning, sexual selection was just another "natural means of selection", although different from standard "natural selection" in its mechanism. But it took Darwin 30 years to fully develop his theory, from the early notebooks to the 1871 book The Descent of Man, and Selection in Relation to Sex. Although there is a remarkable continuity in his basic ideas about sexual selection, he emphasized increasingly the idea that sexual selection could oppose the action of natural selection and be non adaptive. In time, he also gave more weight to mate choice (especially female choice), giving explicit arguments in favor of psychological notions such as "choice" and "aesthetic sense". But he also argued that there was no strict demarcation line between natural and sexual selection, a major difficulty of the theory from the beginning. Female choice was the main reason why Alfred Russel Wallace, the co-discoverer of the principle of natural selection, engaged in a major controversy with Darwin about sexual selection. Wallace was suspicious about sexual selection in general, trying to minimize it by all sorts of arguments. And he denied entirely the existence of female choice, because he thought that it was both unnecessary and an anthropomorphic notion. This had something to do with his spiritualist convictions, but also with his conception of natural selection as a sufficient principle for the evolutionary explanation of all biological phenomena (except for the origin of mind). This is why Wallace proposed to redefine Darwinism in a way that excluded Darwin's principle of sexual selection. The main result of the Darwin-Wallace controversy was that most Darwinian biologists avoided the subject of sexual selection until at least the 1950s, Ronald Fisher being a major exception. This controversy still deserves attention from modern evolutionary biologists, because the modern approach inherits from both Darwin and Wallace. The modern approach tends to present sexual selection as a special aspect of the theory of natural selection, although it also recognizes the big difficulties resulting from the inevitable interaction between these two natural processes of selection. And contra Wallace, it considers mate choice as a major process that deserves a proper evolutionary treatment. The paper's conclusion explains why sexual selection can be taken as a test case for a proper assessment of "Darwinism" as a scientific tradition. Darwin's and Wallace's attitudes towards sexual selection reveal two different interpretations of the principle of natural selection: Wallace's had an environmentalist conception of natural selection, whereas Darwin was primarily sensitive to the element of competition involved in the intimate mechanism of any natural process of selection. Sexual selection, which can lack adaptive significance, reveals this exemplarily. PMID:20338530

  6. Does Sexual Satisfaction Change With Relationship Duration?

    2016-01-01

    Despite a large body of empirical literature on sexual satisfaction, its development over the course of a relationship is still unclear. Only a small number of studies, most of which have relied on cross-sectional data of convenience samples, have explicitly focused on relationship duration, and empirical evidence is mixed. We analyzed how sexual satisfaction changes over the course of a relationship using three waves of the German Family Panel study (pairfam). We concentrated our analyses on young and middle-aged heterosexual individuals in committed relationships (N = 2,814) and applied fixed effects regression models, which have the advantage of estimations based on changes within individuals over time. We found a positive development of sexual satisfaction in the first year of a relationship, followed by a steady decline. This pattern persisted even when controlling for the frequency of intercourse, although the effects were, in part, mediated by intercourse frequency. We explained the non-linear effect of relationship duration on sexual satisfaction with an initial learning effect regarding partner-specific sexual skills, which is then outweighed by a decline in passion at later stages of a relationship. Moreover, we found significant effects for the control variables of health status, intimacy in couple communication, and conflict style, as expected. In contrast to past research, however, cohabitation and marriage were not found to play a role for sexual satisfaction in our data. Further research is required to deepen the understanding of the reasons why sexual satisfaction changes with relationship duration. PMID:26246315

    1989-01-01

    An explicit-explicit subcycling procedure for the finite element analysis of structural dynamics is developed. This procedure has relaxed the usual constraint of requiring integer time step ratios for adjacent nodal groups. This allows for greater advantage to be taken of local stability criteria, and thus improves the efficiency of the explicit time integrator. Example problems are included to demonstrate the accuracy and stability of the method.

  11. Explicit versus spontaneous diffeomorphism breaking in gravity

    NASA Astrophysics Data System (ADS)

    Bluhm, Robert

    2015-03-01

    Gravitational theories with fixed background fields break local Lorentz and diffeomorphism invariance either explicitly or spontaneously. In the case of explicit breaking it is known that conflicts can arise between the dynamics and geometrical constraints, while spontaneous breaking evades this problem. It is for this reason that in the gravity sector of the Standard-Model extension (SME) it is assumed that the background fields (SME coefficients) originate from spontaneous symmetry breaking. However, in other examples, such as Chern-Simons gravity and massive gravity, diffeomorphism invariance is explicitly broken by the background fields, and the potential conflicts between the dynamics and geometry can be avoided in most cases. An analysis of how this occurs is given, and the conditions that are placed on the metric tensor and gravitational structure as a result of the presence of an explicit-breaking background are described. The gravity sector of the SME is then considered for the case of explicit breaking. However, it is found that a useful post-Newtonian limit is only obtained when the symmetry breaking is spontaneous.

  12. Accelerating an iterative process by explicit annihilation

    A slowly convergent stationary iterative process can be accelerated by explicitly annihilating (i.e., eliminating) the dominant eigenvector component of the error. The dominant eigenvalue or complex pair of eigenvalues can be estimated from the solution during the iteration. The corresponding eigenvector or complex pair of eigenvectors can then be annihilated by applying an explicit Richardson process over the basic iterative method. This can be done entirely in real arithmetic by analytically combining the complex conjugate annihilation steps. The technique is applied to an implicit algorithm for the calculation of two dimensional steady transonic flow over a circular cylinder using the equations of compressible inviscid gas dynamics. This demonstrates the use of explicit annihilation on a nonlinear problem.

  13. Sexual picture processing interferes with decision-making under ambiguity.

    2014-04-01

    Many people watch sexually arousing material on the Internet in order to receive sexual arousal and gratification. When browsing for sexual stimuli, individuals have to make several decisions, all possibly leading to positive or negative consequences. Decision-making research has shown that decisions under ambiguity are influenced by consequences received following earlier decisions. Sexual arousal might interfere with the decision-making process and should therefore lead to disadvantageous decision-making in the long run. In the current study, 82 heterosexual, male participants watched sexual pictures, rated them with respect to sexual arousal, and were asked to indicate their current level of sexual arousal before and following the sexual picture presentation. Afterwards, subjects performed one of two modified versions of the Iowa Gambling Task in which sexual pictures were displayed on the advantageous and neutral pictures on the disadvantageous card decks or vice versa (n = 41/n = 41). Results demonstrated an increase of sexual arousal following the sexual picture presentation. Decision-making performance was worse when sexual pictures were associated with disadvantageous card decks compared to performance when the sexual pictures were linked to the advantageous decks. Subjective sexual arousal moderated the relationship between task condition and decision-making performance. This study emphasized that sexual arousal interfered with decision-making, which may explain why some individuals experience negative consequences in the context of cybersex use. PMID:23733155

  14. Does Explicit Expectation Really Affect Preparation?

    PubMed Central

    Umbach, Valentin J.; Schwager, Sabine; Frensch, Peter A.; Gaschler, Robert

    2012-01-01

    Expectation enables preparation for an upcoming event and supports performance if the anticipated situation occurs, as manifested in behavioral effects (e.g., decreased RT). However, demonstrating coincidence between expectation and preparation is not sufficient for attributing a causal role to the former. The content of explicit expectation may simply reflect the present preparation state. We targeted this issue by experimentally teasing apart demands for preparation and explicit expectations. Expectations often originate from our experience: we expect that events occurring with a high frequency in the past are more likely to occur again. In addition to expectation, other task demands can feed into action preparation. In four experiments, frequency-based expectation was pitted against a selective response deadline. In a three-choice reaction time task, participants responded to stimuli that appeared with varying frequency (60, 30, 10%). Trial-by-trial stimulus expectations were either captured via verbal predictions or induced by visual cues. Predictions as well as response times quickly conformed to the variation in stimulus frequency. After two (of five) experimental blocks we forced participants by selective time pressure to respond faster to a less frequent stimulus. Therefore, participants had to prepare for one stimulus (medium frequency) while often explicitly expecting a different one (high frequency). Response times for the less frequent stimulus decreased immediately, while explicit expectations continued to indicate the (unchanged) presentation frequencies. Explicit expectations were thus not just reflecting preparation. In fact, participants responded faster when the stimulus matched the trial-wise expectations, even when task demands discouraged their use. In conclusion, we argue that explicit expectation feeds into preparatory processes instead of being a mere by-product. PMID:23248606

    Context: Adolescence is a very exciting phase of life fraught with many challenges like sexuality. Understanding them is important in helping the adolescents grow up healthily. Aims: To ascertain the attitudes and knowledge about sexuality among school-going adolescents. Settings and Design: Students in two urban schools of an Indian city from class IX to XII were administered a self-reporting questionnaire on matters related to sexuality. Materials and Methods: Requisite ethical clearances were taken as also the consent of the parents and students before administration of the questionnaire. The authors clarified doubts to adolescents. Statistical analysis: Statistical package for social sciences. Results: The incidence of having sexual contact was 30.08% for boys and 17.18% for girls. 6.31% boys and 1.31% girls reported having had experienced sexual intercourse. Friends constituted the main sexual partners for both boys and girls. Sexual abuse had been reported by both girls and boys. These and other findings are discussed in the article. Conclusions: Adolescent school students are involved in sexual activity, but lack adequate knowledge in this regard. Students, teachers, and parents need to understand various aspects of sexuality to be able to help adolescents’ healthy sexual development. PMID:22969181

    2008-04-01

    Limited empirical information exists on whether or not marriage and family therapists are having sexuality-related discussions with their clients. When helping professionals ignore client sexuality, the potential for unintended negative outcomes increases. The researchers surveyed 175 clinical members of the American Association for Marriage and Family Therapy to assess how their clinical training and education, their perceived sexual knowledge, and their comfort with sexual material influenced their willingness to engage in sexuality-related discussions with their clients. The results indicate that sexuality education and supervision experiences are the cornerstone for a therapist's base level of comfort. It is through sexuality education and supervision that sex knowledge is acquired and comfort levels are increased. Once comfort with sexual discussions increases, then therapists are more likely to engage in sexuality discussions with their clients. PMID:18412829

    2013-08-01

    The present study examined men and women's sexual and affective responses to erotic film clips that were combined with different fantasy instructions. Men (n = 29) and women (n = 28) were presented with two types of erotic films (explicit vs. romantic) and two fantasy instructions (fantasizing about one's real-life partner vs. fantasizing about someone else). Genital response, subjective sexual arousal, and affective responses were assessed. Sexually explicit stimuli resulted in larger genital responses; women reported higher subjective sexual arousal than men; and fantasizing about one's partner resulted, overall, in higher subjective sexual arousal and higher levels of positive affect. Moreover, in women, the instruction to fantasize about one's partner resulted in stronger subjective sexual arousal to the explicit film than the instruction to fantasize about someone else. Results suggested that physiological, subjective, and affective responses to erotic film stimuli are impacted not only by stimulus characteristics but also by the viewer's interpretation of the depicted relationship.

    Sexuality is an important component in the lives of menopausal women. Despite the importance of sexual function in menopausal women, sexual dysfunction increases with age. Age-related decline in sexual function may significantly reduce quality of life, making recognition of sexual dysfunction by physicians important for getting menopausal women effective care. Sexual dysfunction can result from multiple etiologies including psychosocial factors, medication side effects, vulvovaginal atrophy, chronic illness, or hypoactive sexual desire disorder. Discovering the etiology and identifying modifiable factors of the sexual function will help define appropriate treatment. PMID:26316248

  15. Implicit versus explicit local contextual processing.

    PubMed

    Fogelson, Noa; Fernandez-Del-Olmo, Miguel

    2013-01-01

    We investigated the effects of implicit local contextual processing using behavioral and electrophysiological measures. EEG recording blocks consisted of targets preceded by either randomized sequences of standards or by sequences including a predictive sequence signaling the occurrence of a target event. Subjects performed two sessions: in the first the regularity of the predictive sequence was implicit, while in the second this regularity was made explicit. Subjects pressed a button in response to targets. Both the implicit and explicit sessions showed shorter reaction times and peak P3b latencies for predicted versus random targets, although to a greater extent in the explicit session. In both sessions the middle and last most-informative stimuli of the three-standard predictive sequence induced a significant larger P3b compared with randomized standards. The findings show that local contextual information is processed implicitly, but that this modulation was significantly greater when subjects were explicitly instructed to attend to target-predictive contextual information. The findings suggest that top-down attentional networks have a role in modulating the extent to which contextual information is utilized. PMID:23785458

  17. Sexual function, sexual abuse and sexually transmitted diseases in adolescence.

    PubMed

    Conard, Lee Ann E; Blythe, Margaret J

    2003-02-01

    As adolescents progress through puberty, many biological changes occur and, for young women, this includes the onset of menses and the capability for reproduction. During this time, sexual identity is developed and expressions of sexuality become more frequent. Adolescent women engage in a variety of sexual behaviours, both non-coital and coital. As teens begin dating relationships, they are at risk for dating violence and sexual abuse. Some may even be raped after sedation with a 'date rape' drug. As adolescents attempt to develop intimate sexual relationships, they may be at high risk for health consequences associated with sexual activity, such as pregnancy and sexually transmitted diseases (STDs). Providers, such as physicians, nurse practitioners, physician assistants and nurses, must know current STD diagnosis and treatment recommendations to decrease morbidity caused by these infections. By knowing how to interview, understanding legal issues and anticipating concerns pertinent to teens, providers have the opportunity to decrease barriers to health care for adolescents.

A questionnaire of this nature could be useful for both clinicians and researchers, because it considers the contextual nature of sexual desire and it draws attention to individual differences in factors that can contribute to sexual desire. Aim The aim of the present study was to create a multidimensional assessment tool of cues for sexual desire in women that is validated in women with and without hypoactive sexual desire disorder (HSDD). Methods Factor analyses conducted on both an initial sample (N = 874) and a community sample (N = 138) resulted in the Cues for Sexual Desire Scale (CSDS) which included four factors: (i) Emotional Bonding Cues; (ii) Erotic/ Explicit Cues; (iii) Visual/Proximity Cues; and (iv) Implicit/Romantic Cues. Main Outcome Measures Scale construction of cues associated with sexual desire and differences between women with and without sexual dysfunction. Results The CSDS demonstrated good reliability and validity and was able to detect significant differences between women with and without HSDD. Results from regression analyses indicated that both marital status and level of sexual functioning predicted scores on the CSDS. The CSDS provided predictive validity for the Female Sexual Function Index desire and arousal domain scores, and increased cues were related to a higher reported frequency of sexual activity in women. Conclusions The findings from the present study provide valuable information regarding both internal and external triggers that can result in sexual desire for women. We believe that the CSDS could be beneficial in therapeutic settings to help identify cues that do and do not facilitate sexual desire in women with clinically diagnosed desire difficulties.

    Though the literature on the diagnosis and treatment of survivors of childhood sexual abuse has burgeoned in the last 20 years, relatively little guidance is available in the popular or professional literature to assist clients or therapists about issues of disclosure of this abuse to family members. When authors explicitly focus on disclosure, the timing of such disclosure is usually framed within a psychological and/or interpersonal perspective. In this article, we suggest that attention to characteristics of the sexual abuse narrative itself offers an important additional resource to guide decision making with respect to disclosure. We also describe ways that a narrative approach to disclosure can produce empowering conversational practices. A detailed case example provides the clinical material to illustrate this narrative approach to disclosure. PMID:8582474

    OBJECTIVES: This study aimed to examine the prevalence of sexting behaviors (sexually explicit messages and/or pictures) among an at-risk sample of early adolescents as well as the associations between sexting behaviors and sexual behaviors, risk-related cognitions, and emotional regulation skills. It also aimed to determine whether differences in risk were associated with text-based versus photo-based sexts. METHODS: Seventh-grade adolescents participating in a sexual risk prevention trial for at-risk early adolescents completed a computer-based survey at baseline regarding sexting behavior (having sent sexually explicit messages and/or pictures), sexual activities, intentions to have sex, perceived approval of sexual activity, and emotional regulation skills. RESULTS: Twenty-two percent of the sample reported having sexted in the past 6 months; sexual messages were endorsed by 17% (n = 71), sexual messages and photos by 5% (n = 21). Pictures were endorsed significantly more often by females (?2[2] = 7.33, P = .03) and Latinos (?2[2] = 7.27, P = .03). Sexting of any kind was associated with higher rates of engaging in a variety of sexual behaviors, and sending photos was associated with higher rates of sexual activity than sending text messages only. This was true for a range of behaviors from touching genitals over clothes (odds ratio [OR] = 1.98, P = .03) to oral sex (OR = 2.66, P < .01) to vaginal sex (OR = 2.23, P < .01). CONCLUSIONS: Sexting behavior (both photo and text messages) was not uncommon among middle school youth and co-occurred with sexual behavior. These data suggest that phone behaviors, even flirtatious messages, may be an indicator of risk. Clinicians, parents, and health programs should discuss sexting with early adolescents. PMID:24394678

    2013-11-01

    Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects.

    2002-01-01

    The present research examined how implicit racial associations and explicit racial attitudes of Whites relate to behaviors and impressions in interracial interactions. Specifically, the authors examined how response latency and self-report measures predicted bias and perceptions of bias in verbal and nonverbal behavior exhibited by Whites while they interacted with a Black partner. As predicted, Whites' self-reported racial attitudes significantly predicted bias in their verbal behavior to Black relative to White confederates. Furthermore, these explicit attitudes predicted how much friendlier Whites felt that they behaved toward White than Black partners. In contrast, the response latency measure significantly predicted Whites' nonverbal friendliness and the extent to which the confederates and observers perceived bias in the participants' friendliness.

    1997-12-01

    In this paper the development of a master-slave robotics system is presented. This development is part of a research project devoted to the intelligent automation of in-service inspection of welded seams in nuclear plants using non- destructive ultrasonic based techniques. The main feature of the system is a shared explicit control scheme of the contact force during the interaction of the end-effector with the remote environment. This unilateral master-slave operational scheme does not suffer from the drawbacks of the bilateral force reflection based implementation. Moreover it avoids the operator from damaging the remote manipulator during wrong maneuvers due to imperfect video feedback. The paper describes the control structure applied (belonging to the class of explicit force control) and the hardware-software architecture of the system. Experimental results are given on the Ansaldo Olasand manipulator.

  15. Adolescent sexual orientation.

    PubMed

    Spigarelli, Michael G

    2007-12-01

    Sexual orientation has been defined as the patterns of sexual thoughts, fantasies, and attractions that an individual has toward other persons of the same or opposite gender. Throughout childhood and approaching adolescence, children try to understand their own sexuality and sexual orientation in the context of the society in which they live. Typically, this attempt to understand first occurs in thoughts of a sexual nature and later through actions, usually before sexual orientation is clearly defined. How these experiences are handled, by the individual and close friends and relatives, helps to define how an individual views and accepts their sexual orientation ultimately as an adult.

    2014-01-01

    New digital technologies are highly responsive to many of the developmental needs of adolescents, including their need for intimate connection and social identity. This chapter explores adolescents' use of web-based sexual information, texting and "sexting," online dating sites, role-playing games, and sexually explicit media, and presents new data comparing the interpersonal and intrapersonal health outcomes among youth who engage in online sexual activities to those who do not. Despite the media-stoked concerns surrounding adolescents' participation in online sexual activities, the ubiquity of online activities and close overlap between online and offline activities indicate that this type of behavior should not be pathologized or used as a metric of problem behavior. The chapter concludes with implications for parents, educators, researchers, counselors, and health care providers, a call to challenge our deep discomfort around adolescent sexuality and to harness these technologies in ways that help promote growth and positive development.

  17. Sexual arousal, is it for mammals only?

    PubMed Central

    Ball, Gregory F.; Balthazart, Jacques

    2012-01-01

    Sexual arousal has many dimensions and has consequently been defined in various ways. In humans sexual arousal can be assessed based in part on verbal communication. In male non-human mammalian species it has been argued that arousal can only be definitively inferred if the subject exhibits a penile erection in a sexual context. In non-mammalian species that lack an intromittent organ, as is the case for most avian species, the question of how to assess sexual arousal has not been thoroughly addressed. Based on studies performed in male Japanese quail, we argue that several behavioral or physiological characteristics provide suitable measures of sexual arousal in birds and probably also in other tetrapods. These indices include the performance of appetitive sexual behavior in anticipation of copulation (although anticipation and arousal are not the synonyms), the activation of specific brain areas as identified by the detection of the expression of immediate early genes (fos, egr-1) or by 2-deoxygucose quantitative autoradiography, and above all the release of dopamine in the medial preoptic areas as measured by in vivo dialysis. Based on these criteria, it is possible to assess in birds sexual arousal in its broadest sense but meeting the more restrictive definition of arousal proposed for mammals (erection in an explicit sexual context) is and will probably remain impossible in birds until refinement of in vivo imaging techniques such fMRI allow us to match in different species, with and without an intromittent organ, the brain areas that are activated in the presence of specific stimuli.

  18. Implicit and Explicit Spacecraft Gyro Calibration

    NASA Technical Reports Server (NTRS)

    Bar-Itzhack, Itzhack Y.; Harman, Richard R.

    2004-01-01

    This paper presents a comparison between two approaches to sensor calibration. According to one approach, called explicit, an estimator compares the sensor readings to reference readings, and uses the difference between the two to estimate the calibration parameters. According to the other approach, called implicit, the sensor error is integrated to form a different entity, which is then compared with a reference quantity of this entity, and the calibration parameters are inferred from the difference. In particular this paper presents the comparison between these approaches when applied to in-flight spacecraft gyro calibration. Reference spacecraft rate is needed for gyro calibration when using the explicit approach; however, such reference rates are not readily available for in-flight calibration. Therefore the calibration parameter-estimator is expanded to include the estimation of that reference rate, which is based on attitude measurements in the form of attitude-quaternion. A comparison between the two approaches is made using simulated data. It is concluded that the performances of the two approaches are basically comparable. Sensitivity tests indicate that the explicit filter results are essentially insensitive to variations in given spacecraft dynamics model parameters.

  19. Age effects on explicit and implicit memory

    PubMed Central

    Ward, Emma V.; Berry, Christopher J.; Shanks, David R.

    2013-01-01

    It is well-documented that explicit memory (e.g., recognition) declines with age. In contrast, many argue that implicit memory (e.g., priming) is preserved in healthy aging. For example, priming on tasks such as perceptual identification is often not statistically different in groups of young and older adults. Such observations are commonly taken as evidence for distinct explicit and implicit learning/memory systems. In this article we discuss several lines of evidence that challenge this view. We describe how patterns of differential age-related decline may arise from differences in the ways in which the two forms of memory are commonly measured, and review recent research suggesting that under improved measurement methods, implicit memory is not age-invariant. Formal computational models are of considerable utility in revealing the nature of underlying systems. We report the results of applying single and multiple-systems models to data on age effects in implicit and explicit memory. Model comparison clearly favors the single-system view. Implications for the memory systems debate are discussed. PMID:24065942

  20. Getting the 'blues': the existence, diffusion and influence of pornography on young peoples' sexual health in Sierra Leone.

    Day, Andrea

    2014-01-01

    While substantial research has examined the effects of pornography on young people in developed societies, existing studies fall short in addressing how sexually-explicit material affects young people in developing countries. The importance of such knowledge increases as the globalising effects of technology expand young peoples' access and exposure to pornography. During the summer of 2012, a study was undertaken in Sierra Leone examining factors affecting young peoples' sexual and reproductive health. The research assessed the influence of HIV knowledge, communication about sex, civil war and contraception myths on sexual behaviours, while remaining open to unanticipated factors. During data collection, respondents identified pornography, also called blues, as an influential factor, detailing its newfound accessibility driven by improved access to information and communication technologies in the country. Respondents also addressed several presumed ways in which pornography impacts young peoples' decisions about sexual health. The following study examines perceived effects of young peoples' exposure to pornography based on existing literature. It then outlines the findings of research conducted in Sierra Leone, drawing on primary data from the respondents and relevant published literature and concludes with proposals for addressing its negative effects.

  1. Sexuality and Islam.

    PubMed

    Dialmy, Abdessamad

    2010-06-01

    This paper deals with three major questions: (1) What are the sexual norms defined by the sacred texts (Koran and Sunna)? (2) What are the sexual practices currently observed among Moslems? (3) To which extent are current sexual practices of Moslems dissociated from Islamic sexual norms? Sexual standards in Islam are paradoxical: on the one hand, they allow and actually are an enticement to the exercise of sexuality but, on the other hand, they discriminate between male and female sexuality, between marital and pre- or extramarital sexuality, and between heterosexuality and homosexuality. Men are given more rights with regard to the expression of their sexuality; women are forbidden to have extramarital sex (with their slaves) and both genders to have homosexual relationships. The combination of these paradoxical standards with modernisation leads to the current back and forth swing of sexual practices between repression and openness. Partial modernisation leads to greater sexual tolerance. But restrictive sexual standards have gathered strength and have become idealised as a result of the current radicalisation of Islam. This swing of the pendulum between repression and openness is illustrated by phenomena such as public harassment, premarital sexuality, female pleasure, prostitution, and homosexuality. Currently, Islam is not any more the only reference which provides guidance concerning sexual practices but secularisation of sexual laws is still politically unthinkable today. So the only solution is to achieve reform in the name of Islam, through the reinterpretation of repressive holy texts. PMID:20441406

    2007-10-01

    Explicit elasticity-conductivity connections for anisotropic heterogeneous materials were recently derived and verified experimentally by the present authors. The constituents were assumed isotropic, so that the overall anisotropy was due solely due to nonrandom orientations of inhomogeneities. Motivated by the materials science applications that deal with strongly anisotropic inclusions, we derive alternative elasticity-conductivity connections that cover these cases. They hold for a broad class of orientation distributions—up to three families of parallel inhomogeneities forming arbitrary angles with each other, with moderate orientation scatter allowed in each of the families. In the case of the isotropic inhomogeneities, this form has substantially better accuracy than the approximate connections derived earlier. The results are compared with experimental data on fiber-reinforced plastics. The agreement is quite good for the entire set of the effective anisotropic constants, and it is achieved without any fitting parameters.

  6. Labor experiences of childhood sexual abuse survivors.

    Rhodes, N; Hutchinson, S

    1994-12-01

    This field study used the ethnographic method to describe and analyze the labor experiences of childhood sexual abuse survivors. The sample included seven sexual abuse survivors, five nurse-midwives, and three labor and delivery nurses. Data collection included in-depth interviews, participant observation in labor and delivery over a period of six years, and anecdotal material from the literature. Analysis followed Spradley's Developmental Research Sequence and included domain, taxonomic, componential and theme analysis. Women reported both forgetting and remembering abusive incidents, and described labor sensations reminiscent of sexual abuse. A heuristic for appraising labor styles suggestive of past sexual abuse includes fighting, taking control, surrendering, and retreating. These styles are considered extremes of women's reactions to labor and are directly linked to posttraumatic stress disorder. This study demonstrated that it is important for perinatal caregivers to understand the link between childhood sexual abuse and childbirth so that they can assist women to have a positive birth experience.

    2015-12-01

    The goal of this study was to investigate whether exposure to sexual reality television content and Internet pornography (IP) is related to sexual self-presentation on social media. Based on a two-wave panel survey among 1,765 adolescents aged 13-17 years, we found that watching sexual reality television content stimulated adolescents to produce and distribute sexual images of themselves on social media. In turn, sexual self-presentation on social media led adolescents to watch sexual reality television content more frequently. These relationships were similar among boys and girls. No reciprocal relationship between exposure to IP and boys' and girls' sexual self-presentation on social media was found. The results suggest that sexual content in mainstream mass media may predict adolescents' sexually oriented behavior on social media and vice versa. Moreover, adolescents seem to differentiate between types of sexual content (i.e., mainstream versus more explicit sexual content) when incorporating sexual media content in their sexual behavior online.

    Background Consensus techniques have been used previously to create explicit criteria to prioritize cataract extraction; however, the appropriateness of the intervention was not included explicitly in previous studies. We developed a prioritization tool for cataract extraction according to the RAND method. Methods Criteria were developed using a modified Delphi panel judgment process. A panel of 11 ophthalmologists was assembled. Ratings were analyzed regarding the level of agreement among panelists. We studied the effect of all variables on the final panel score using general linear and logistic regression models. Priority scoring systems were developed by means of optimal scaling and general linear models. The explicit criteria developed were summarized by means of regression tree analysis. Results Eight variables were considered to create the indications. Of the 310 indications that the panel evaluated, 22.6% were considered high priority, 52.3% intermediate priority, and 25.2% low priority. Agreement was reached for 31.9% of the indications and disagreement for 0.3%. Logistic regression and general linear models showed that the preoperative visual acuity of the cataractous eye, visual function, and anticipated visual acuity postoperatively were the most influential variables. Alternative and simple scoring systems were obtained by optimal scaling and general linear models where the previous variables were also the most important. The decision tree also shows the importance of the previous variables and the appropriateness of the intervention. Conclusion Our results showed acceptable validity as an evaluation and management tool for prioritizing cataract extraction. It also provides easy algorithms for use in clinical practice.

    India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality. PMID:23858263

    2000-01-01

    Although many parents realize the importance of educating their children about sexuality, many of them find themselves unable to address the subject comfortably. In addition to their own discomfort, parents are concerned about how their children would feel about discussing sex with them. Parents who are unwilling or unable to discuss this important and sensitive part of life with their children present sexuality in a negative way and as a taboo rather than a natural part of being human. The author states that ¿no sexuality education is sexuality education,¿ and the message received from this lack of education may be a negative one. As a consequence, children who receive a negative message of sexuality from their parents are unlikely to turn to their parents to discuss sexual matters as they get older. On the other hand, positive communication about sexual information with children leads to ongoing discussions as they mature. Establishing an environment conducive to open and comfortable communication is therefore highly critical. The following are some tips for parents when educating their children about sexuality: 1) be approachable, 2) be accepting, 3) discuss issues and answer questions simply, and 4) discuss issues and answer questions honestly. Programs sponsored by local schools, civic organizations or religious groups can help narrow the gap that exists between parents and their children concerning human sexuality. PMID:11030266

    2011-11-01

    Computing hardware is trending towards distributed, massively parallel architectures in order to achieve high computational throughput. For example, Intrepid at Argonne uses 163,840 cores, and next generation machines, such as Sequoia at Lawrence Livermore, will use over one million cores. Harnessing the increasingly parallel nature of computational resources will require algorithms that scale efficiently on these architectures. The advent of GPU-based computation will serve to accelerate this behavior, as a single GPU contains hundreds of processor ``cores.'' Explicit algorithms avoid the communication associated with a linear solve, thus parallel scalability of these algorithms is typically high. This work will explore the efficiency and accuracy of three explicit solution methodologies for the Navier-Stokes equations: traditional artificial compressibility schemes, the lattice-Boltzmann method, and the recently proposed kinetically reduced local Navier-Stokes equations [Borok, Ansumali, and Karlin (2007)].

  13. Explicit Green functions for hierarchical lattices

    NASA Astrophysics Data System (ADS)

    Schwalm, W. A.; Reese, C. C.; Wagner, C. J.; Schwalm, M. K.

    1994-06-01

    Explicit formulas for one-electron propagators x and y between same and distal corner sites are given for several families of hierarchical lattices. These give x and y as a function of lattice size for a set of energies dense in the Cantor portion of the spectrum of the large-lattice limit. With linear chains as quantum lead wires, the Kubo-Greenwood conductance is expressed succinctly in terms of x and y. Lattice families treated are (1) the Sierpi?ski simplex family scrS of Dhar in Euclidean dimension k, (2) the scrR family introduced previously, also k dimensions, (3) a star-delta dual to the scrR family, (4) a two-parameter family of k dimensional, q sheeted lattices related to those of de Menezes and de Magãlhaes, (5) a dual to the two-parameter family, and (6) the first several members of a family related to the lattices of Hilfer and Blumen. The exact results derive from a formalism for solving the dynamics of the renormalization map explicitly. Special properties that make the renormalization maps solvable are enumerated, and the general solution procedure is reviewed. Power-law scaling of conductance with lattice size is found at special energies for each lattice. In several cases there are uncountably many energies at which conductance becomes independent of lattice size.

    Epidemiological models can provide crucial understanding about the dynamics of infectious diseases. Possible applications range from real-time forecasting and allocation of health care resources to testing alternative intervention mechanisms such as vaccines, antibiotics or the improvement of sanitary conditions. We apply a spatially explicit model to the cholera epidemic that struck Haiti in October 2010 and is still ongoing. The dynamics of susceptibles as well as symptomatic and asymptomatic infectives are modelled at the scale of local human communities. Dissemination of Vibrio cholerae through hydrological transport and human mobility along the road network is explicitly taken into account, as well as the effect of rainfall as a driver of increasing disease incidence. The model is calibrated using a dataset of reported cholera cases. We further model the long term impact of several types of interventions on the disease dynamics by varying parameters appropriately. Key epidemiological mechanisms and parameters which affect the efficiency of treatments such as antibiotics are identified. Our results lead to conclusions about the influence of different intervention strategies on the overall epidemiological dynamics.

  15. American Academy of Pediatrics. Policy statement--sexuality, contraception, and the media.

    PubMed

    2010-09-01

    From a health viewpoint, early sexual activity among US adolescents is a potential problem because of the risk of pregnancy and sexually transmitted infections. New evidence points to the media adolescents use frequently (television, music, movies, magazines, and the Internet) as important factors in the initiation of sexual intercourse. There is a major disconnect between what mainstream media portray-casual sex and sexuality with no consequences-and what children and teenagers need-straightforward information about human sexuality and the need for contraception when having sex. Television, film, music, and the Internet are all becoming increasingly sexually explicit, yet information on abstinence, sexual responsibility, and birth control remains rare. It is unwise to promote "abstinence-only" sex education when it has been shown to be ineffective and when the media have become such an important source of information about "nonabstinence." Recommendations are presented to help pediatricians address this important issue. PMID:20805150

  16. Ethical issues in therapy: therapist self-disclosure of sexual feelings.

    PubMed

    Fisher, Craig D

    2004-01-01

    Although therapist sexual attraction to clients is common, and therapist self-disclosure is an often-used intervention, therapist self-disclosure of sexual feelings to clients is an understudied phenomenon. In this article, I critically review the small base of literature on therapist self-disclosure of sexual feelings, including information on prevalence rates, empirical research, and case studies. By incorporating these findings with information from relevant sections of the American Psychological Association (2002) Ethics Code, my intent is to evaluate different aspects of therapist self-disclosure of sexual feelings and arrive at conclusions regarding therapists' use of these disclosures. It appears that direct, explicit disclosure of sexual feelings can run the risk of harming clients and may therefore be unethical. Therefore, the use of this technique is discouraged. I discuss the issue of using less explicit interventions. PMID:15835034

    This study presents an accurate and robust boundary model, the explicitly represented polygon (ERP) wall boundary model, to treat arbitrarily shaped wall boundaries in the explicit moving particle simulation (E-MPS) method, which is a mesh-free particle method for strong form partial differential equations. The ERP model expresses wall boundaries as polygons, which are explicitly represented without using the distance function. These are derived so that for viscous fluids, and with less computational cost, they satisfy the Neumann boundary condition for the pressure and the slip/no-slip condition on the wall surface. The proposed model is verified and validated by comparing computed results with the theoretical solution, results obtained by other models, and experimental results. Two simulations with complex boundary movements are conducted to demonstrate the applicability of the E-MPS method to the ERP model.

    This study examined sexual risk behaviors and sexual refusal assertiveness in relationship to child sexual abuse, emotion dysregulation, and adult sexual revictimization. Path analyses of 1,094 survivors who had sex in the past year were done to examine sexual risk behavior and sexual refusal assertiveness mediational pathways by which child sexual abuse severity and emotion dysregulation may affect revictimization over one year in adult female sexual assault survivors. Exchanging sex for money and sexual refusal assertiveness were significantly associated with emotion dysregulation, whereas exchanging sex for money, and not sexual refusal assertiveness, was only significantly related to child sexual abuse severity. Both exchanging sex for money and sex refusal assertiveness mediated the relationship between emotion dysregulation and adult sexual revictimization. Exchanging sex for money mediated the child sexual abuse severity-revictimization relationship. These findings demonstrate the importance of considering both risky and protective sexual behaviors in research and prevention programming that address sexual revictimization in women. PMID:25942287

    Background: Sexual activity is an important part of the human being's life but this instinct could be influenced by some factors such as diseases, drug using, aging, and menopause. But information about that is limited. Aim: The aim of this study is to determine the status of sexual activity among married menopausal women in Amol, Iran. Materials and Methods: This descriptive analytical study was conducted to describe the sexual activity and sexual dysfunction of women after menopause. Data were collected from health centers in Amol from 280 married women using a questionnaire (self-completed or by interview). Finding: Mean age of subjects were 55.9 ± 6.02 years. 23.4% of subjects reported that their sexual intercourse had been low. 70% of subjects reported a decrease in their sexual activities after menopause. Sexual dysfunctions includes sexual desire disorder 80% arousal dysfunction 80%, orgasmic dysfunction 25%, dyspareunia 55.6%, and lack of sexual satisfaction 43.2%. Conclusion: Findings revealed high percentage of sexual desire disorder and sexual arousal disorder in menopausal women. Therefore, we should have emphasis on counseling and education about sexual activities during the menopause period. PMID:22408336

    2014-01-01

    Previous functional magnetic resonance imaging and event-related brain potential studies revealed that performing a cognitive task may suppress the preferential processing of emotional stimuli. However, these studies utilized simple and artificial tasks (i.e. letter, shape or orientation discrimination tasks), unfamiliar to the participants. The present event-related potential study examined the emotion–attention interaction in the context of a comparably more natural scene categorization task. Deciding whether a natural scene contains an animal or not is a familiar and meaningful task to the participants and presumed to require little attentional resources. The task images were presented centrally and were overlaid upon emotional or neutral background pictures. Thus, implicit emotion and explicit semantic categorization may compete for processing resources in neural regions implicated in object recognition. Additionally, participants passively viewed the same stimulus materials without the demand to categorize task images. Significant interactions between task condition and emotional picture valence were observed for the occipital negativity and late positive potential. In the passive viewing condition, emotional background images elicited an increased occipital negativity followed by an increased late positive potential. In contrast, during the animal-/non-animal-categorization task, emotional modulation effects were replaced by strong target categorization effects. These results suggest that explicit semantic categorization interferes with implicit emotion processing when both processes compete for shared resources. PMID:24194577

    Asexual worms of an exclusively fissiparous strain (the OH strain) of the planarian Dugesia ryukyuensis keep developing hermaphroditic reproductive organs and eventually undergo sexual reproduction instead of asexual reproduction, namely fission, if they are fed with sexually mature worms of an exclusively oviparous planarian, Bdellocephala brunnea, suggesting that the sexually mature worms has a sexualizing substance(s). The fully sexualized worms no longer need the feeding on sexual worms to maintain the sexuality. Here, we demonstrate that the sexualized worms produce enough of their own sexualizing substance similar to that contained in B. brunnea. In case of surgical ablation of the sexualized worms, the fragments with sexual organs regenerate to become sexual, while those without sexual organs, namely head fragments, regenerate to return to the asexual state. The asexual regenerants from the sexualized worms are also fully sexualized by being fed with B. brunnea. Additionally, it was reported that head region in sexually mature worms lacks the putative sexualizing substance necessary for complete sexualization (Sakurai, 1981). These results suggest that the fragments without sexual organ lack enough of an amount of the putative sexualizing substance and the sexuality is maintained by the sexualizing substance contained in the sexualized worms.

    The purpose of this study was to determine whether religiosity, spirituality, and sexual attitudes accounted for differences in sexual behaviors among college students. The sample included 960 college students enrolled at four northeastern colleges. Results indicated differences in sexual attitudes, religiosity, and spirituality by gender. Moreover, sexual attitudes, religiosity, and spirituality were associated with sexual behaviors among college students. Sexual behaviors among males were influenced by their sexual attitudes, religiosity, and spirituality, while for females, their sexual behaviors were mostly influenced by their sexual attitudes. College health professionals can use these findings when discussing sexual practices with students. PMID:21822743

    Improving the transparency and quality of reporting in biomedical research is considered ethically important; yet, this is often based on practical reasons such as the facilitation of peer review. Surprisingly, there has been little explicit discussion regarding the ethical obligations that underpin reporting guidelines. In this commentary, we suggest a number of ethical drivers for the improved reporting of research. These ethical drivers relate to researcher integrity as well as to the benefits derived from improved reporting such as the fair use of resources, minimizing risk of harms, and maximizing benefits. Despite their undoubted benefit to reporting completeness, questions remain regarding the extent to which reporting guidelines can influence processes beyond publication, including researcher integrity or the uptake of scientific research findings into policy or practice. Thus, we consider investigation on the effects of reporting guidelines an important step in providing evidence of their benefits. PMID:26979591

    The paper presents a closed loop guidance law for the exoatmospheric trajectory of a launch vehicle. This algorithm has been especially developed for manned mission. The main objectives of this investigation were optimization, accuracy and reliability. Another great issue was to reduce the mission analysis. The explicit guidance generates onboard the optimal path to the desired orbit while optimizing fuel consumption, and respecting some constraints. The computation of the steering law is based on an analytical integration of the trajectory which is divided in a little number of segments. Intermediate constraints such as thermal flux, stage footprint, radar visibility, are applied at the end of the segments. At the final point five orbital parameters are targetted. The steering law parameters are updated at each guidance cycle to cancel predicted constraint errors, using a linear differential correction method. Simulations tested this algorithm with respect to accuracy, optimization, reconfiguration capability. Results are very good compared with off-line optimization.

  11. Materialism.

    2012-05-01

    Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person's mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization and supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, and emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

  18. Comparative Efficiency of Implicit, Explicit and Implicit-Explicit Strong Stability Preserving Methods

    2012-11-01

    Several unsteady problems in transport phenomena require highly accurate solutions. Attempts to increase accuracy order of most numerical schemes, however, often weaken their linear and/or nonlinear stability. On the other hand, Strong Stability Preserving (SSP) methods are able to increase their accuracy order in time while still maintaining the overall stability properties of the original forward Euler method from which they were generated. This is achieved by, among other things, restricting the maximum allowed time step of these schemes. Hence, most recent studies have focused on developing optimal SSP schemes, i.e., minimally restrictive. Under this context, a significant variety of explicit and implicit formulations for multi-step and multi-stage marching schemes of different accuracy orders has been created. Despite their popularity, some open issues still remain. Linear stability of implicit schemes usually allows very large time steps, making them cost effective for many applications when compared to their explicit counterparts. Hence, the SSP time step restriction might render these schemes comparatively inefficient. The present study evaluates different explicit, implicit and implicit-explicit SSP time integration schemes for a series of test cases in an attempt to distinguish the most efficient scheme according to an error / computer time analysis. All three schemes employed a second order TVD flux limiter discretization for the spatial derivatives.

    The study of sexually antagonistic (SA) traits remains largely limited to dioecious (separate sex), mobile animals. However, the occurrence of sexual conflict is restricted neither by breeding system (the mode of sexual reproduction, e.g. dioecy or hermaphroditism) nor by sessility. Here, we synthesize how variation in breeding system can affect the evolution and expression of intra- and inter-locus sexual conflicts in plants and animals. We predict that, in hermaphrodites, SA traits will (i) display lower levels of polymorphism; (ii) respond more quickly to selection; and (iii) involve unique forms of interlocus conflict over sex allocation, mating roles and selfing rates. Explicit modelling and empirical tests in a broader range of breeding systems are necessary to obtain a general understanding of the evolution of SA traits. PMID:19553248

  2. Explicit 3D continuum fracture modeling with smooth particle hydrodynamics

    NASA Technical Reports Server (NTRS)

    Benz, W.; Asphaug, E.

    1993-01-01

    Impact phenomena shaped our solar system. As usual for most solar system processes, the scales are far different than we can address directly in the laboratory. Impact velocities are often much higher than we can achieve, sizes are often vastly larger, and most impacts take place in an environment where the only gravitational force is the mutual pull of the impactors. The Smooth Particle Hydrodynamics (SPH) technique has been applied in the past to the simulations of giant impacts. In these simulations, the colliding objects were so massive (at least a sizeable fraction of the Earth's mass) that material strength was negligible compared to gravity. This assumption can no longer be made when the bodies are much smaller. To this end, we have developed a 3D SPH code that includes a strength model to which we have added a von Mises yielding relation for stresses beyond the Hugoniot Elastic Limit. At the lower stresses associated with brittle failure, we use a rate-dependent strength based on the nucleation of incipient flaws whose number density is given by a Weibull distribution. Following Grady and Kipp and Melosh et al., we introduce a state variable D ('damage'), 0 less than D less than 1, which expresses the local reduction in strength due to crack growth under tensile loading. Unfortunately for the hydrodynamics, Grady and Kipp's model predicts which fragments are the most probable ones and not the ones that are really formed. This means, for example, that if a given laboratory experiment is modeled, the fragment distribution obtained from the Grady-Kipp theory would be equivalent to a ensemble average over many realizations of the experiment. On the other hand, the hydrodynamics itself is explicit and evolves not an ensemble average but very specific fragments. Hence, there is a clear incompatibility with the deterministic nature of the hydrodynamics equations and the statistical approach of the Grady-Kipp dynamical fracture model. We remedy these shortcomings by making the incipient flaw distribution explicit, i.e., particles carry activation strains which are distributed at random with a probability of occurrence given by the Weibull distribution. If the local principal axis strain exceeds this limit, damage starts to grow. By growing explicit cracks together with statistical cracks (damage) at the sub-particle scale, we ensure that material strength and fragmentation is independent of model resolution. We tested our scheme by simulating laboratory impact experiments on basalt spheres.

    Women experience multiple changes in social and reproductive statuses across the life span which can affect sexual functioning. Various phases of the sexual response cycle may be impacted and can lead to sexual dysfunction. Screening for sexual problems and consideration of contributing factors such as neurobiology, reproductive life events, medical problems, medication use, and depression can help guide appropriate treatment and thereby improve the sexual functioning and quality of life of affected women. Treatment options include psychotropic medications, hormone therapy, and psychotherapy. PMID:26830886

    A closed case-file review of 211 sexual homicides identified 16 cases of necrophilia. The results of this unique descriptive study of necrophilia associated with sexual homicide provide information on crime-scene locations, methods of killing, body disposition, premortem sexual assault, specifics of the necrophilic acts, methods of victim abduction, and motivational dynamics. The findings suggest that the most common explanation for necrophilia-the offender's desire to have an unresisting partner-may not always be applicable in cases where this rare paraphilia is connected to sexual murder. The possibility of using crime-scene behaviors in these cases to investigate serial sexual murders is offered. PMID:20102474

    The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment. PMID:26003236

    This study investigated the association between drugs and sexual behavior in a sample of polydrug substance abusers recruited from several Italian therapeutic communities; participants were 90 polydrug substance abusers (opiates, cocaine, amphetamine, inhalants, marijuana/sedatives or hallucinogens abusers) who were compared with 90 nonsubstance-abusing individuals. Sexual behavior was measured by the Italian version of the Sex and the Average Woman (or Man; SAWM), a questionnaire that assesses different kind of sexual attitudes. Results showed that drug-abusing individuals are particularly inclined to search for sexual intercourse and are open to different kinds of sexual experiences; however, they have difficulties in establishing committed and deep relationships with their partners, showing signs of inhibition, affective detachment or anger. Their sexual lives are also surrounded by negative emotions, disturbing thoughts and maladjusted behaviors. The importance of integrating sexual problems into therapeutic strategies is discussed.

    Recent discussions highlighted adolescents' sexual behaviour, but published studies concentrate on specific problems or subgroups of patients without addressing factors related to sexuality. To obtain a broad picture we studied two groups of adolescents attending genito-urinary medicine/sexually transmitted disease (STD) clinics in contrasting areas of Britain, inner London and Swansea. These were evaluated for referral pattern, sexual partner, contraception, obstetric history, sexually transmitted disease, and cervical cytology findings. Over half the adolescents referred themselves but few doctors other than general practitioners referred patients. Sexual partners were regarded by males as casual but by females as regular. Only 66% (81) of females practised contraception. Adolescents had more STD's than the total clinic population except for genital herpes simplex infection, and a high prevalence of genital warts in females has important future implications. The main conclusions were that there is a need for sexually related education targetted at adolescents and their health care providers, especially doctors. PMID:2614765

    Computational simulations are invaluable in elucidating the dynamics of biological macromolecules. Unfortunately, reactions present a fundamental challenge. Calculations based on quantum mechanics can predict bond formation and rupture; however they suffer from severe length- and time-limitations. At the other extreme, classical approaches provide orders of magnitude faster simulations; however they regard chemical bonds as immutable entities. A few exceptions exist, but these are not always trivial to adopt for routine use. We bridge this gap by providing a novel, pseudo-classical approach, based on explicit valency. We unpack molecules into valence electron pairs and atomic cores. Particles bear ionic charges and interact via pairwise-only potentials. The potentials are informed of quantum effects in the short-range and obey dissociation limits in the long-range. They are trained against a small set of isolated species, including geometries and thermodynamics of small hydrides and of dimers formed by them. The resulting force field captures the essentials of reactivity, polarizability and flexibility in a simple, seamless setting. We call this model LEWIS, after the chemical theory that inspired the use of valence pairs. Following the introduction in Chapter 1, we initially focus on the properties of water. Chapter 2 considers gas phase clusters. To transition to the liquid phase, Chapter 3 describes a novel pairwise long-range compensation that performs comparably to infinite lattice summations. The approach is suited to ionic solutions in general. In Chapters 4 and 5, LEWIS is shown to correctly predict the dipolar and quadrupolar response in bulk liquid, and can accommodate proton transfers in both acid and base. Efficiency permits the study of proton defects at dilutions not accessible to experiment or quantum mechanics. Chapter 6 discusses explicit valency approaches in other hydrides, forming the basis of a reactive organic force field. Examples of simple proton transfer and more complex reactions are discussed. Chapter 7 provides a framework for variable electron spread. This addition resolves some of the inherent limitations of the former model which implicitly assumed that electron spread was not affected by the environment. A brief summary is provided in Chapter 8.

    Waterborne pathogens cause many possibly lethal human diseases. We derive the condition for pathogen invasion and subsequent disease outbreak in a territory with specific, space-inhomogeneous characteristics (hydrological, ecological, demographic, and epidemiological). The criterion relies on a spatially explicit model accounting for the density of susceptible and infected individuals and the pathogen concentration in a network of communities linked by human mobility and the water system. Pathogen invasion requires that a dimensionless parameter, the dominant eigenvalue of a generalized reproductive matrix J0, be larger than unity. Conditions for invasion are studied while crucial parameters (population density distribution, contact and water contamination rates, pathogen growth rates) and the characteristics of the networks (connectivity, directional transport, water retention times, mobility patterns) are varied. We analyze both simple, prototypical test cases and realistic landscapes, in which optimal channel networks mimic the water systems and gravitational models describe human mobility. Also, we show that the dominant eigenvector of J0 effectively portrays the geography of epidemic outbreaks, that is, the areas of the studied territory that will be initially affected by an epidemic. This is important for planning an efficient spatial allocation of interventions (e.g., improving sanitation and providing emergency aid and medicines). PMID:23933724

  11. Photon dose calculation incorporating explicit electron transport.

    1995-07-01

    Significant advances have been made in recent years to improve photon dose calculation. However, accurate prediction of dose perturbation effects near the interfaces of different media, where charged particle equilibrium is not established, remain unsolved. Furthermore, changes in atomic number, which affect the multiple Coulomb scattering of the secondary electrons, are not accounted for by current photon dose calculation algorithms. As local interface effects are mainly due to the perturbation of secondary electrons, a photon-electron cascade model is proposed which incorporates explicit electron transport in the calculation of the primary photon dose component in heterogeneous media. The primary photon beam is treated as the source of many electron pencil beams. The latter are transported using the Fermi-Eyges theory. The scattered photon dose contribution is calculated with the dose spread array [T.R. Mackie, J.W. Scrimger, and J.J. Battista, Med. Phys. 12, 188-196 (1985)] approach. Comparisons of the calculation with Monte Carlo simulation and TLD measurements show good agreement for positions near the polystyrene-aluminum interfaces. PMID:7565390

  16. Youth Who Sexual Offended

    2015-01-01

    There has been an increased focus on understanding youth sexual offending in recent years, but there has been limited empirical research on the causes, pathways, and treatment of youth who have sexually offended—especially within a non-Western context. The Good Lives and Self-Regulation Models have often been used to understand and rehabilitate adult sexual offenders, but (unfortunately) there is scant research on youth who sexually offended using these models. The present study aims to describe the different primary goods that are associated with youth sexual offending behaviors in an Asian context. In addition, the study sought to explore whether the age of victim (child vs. nonchild) and nature of sexual offense (penetrative vs. nonpenetrative) influenced the youth’s engagement in offense pathways. The results suggest that pleasure, relatedness, and inner peace were the primary human goods that were most sought after by a sample of 168 youth who sexually offended in Singapore. In addition, offender classification (in relation to the age of victim and nature of sexual offense) influenced the pathways to sexual offending. Therefore, these findings have important clinical implications for assessment, management, and intervention planning for youth who sexually offended. PMID:24048701

  17. Safer sexual decision making in adolescent women: perspectives from the conflict theory of decision-making.

    Adolescent women are at risk for unintended pregnancies and sexually transmitted diseases, including human immune deficiency virus (HIV)/acquired immunodeficiency deficiency syndrome (AIDS), if they do not engage in safer sexual practices. Adolescent women are biologically, behaviorally, and socially more at risk for sexually transmitted diseases (STDs) and HIV than adolescent men. Although abstinence is the safest sexual health practice for adolescent women, once sexual activity begins, safer sexual practices involve condom and contraceptive use, and communicating with sexual partners to negotiate condom use. A number of implicit and explicit decisions are involved in these activities. A number of researchers have examined safer sexual decisions of adolescent women, some of whom have used theory models such as the Transtheoretical Model of Change. Although these findings have contributed to the knowledge base about safer sexual decision making, many questions remain unanswered about how adolescent women make safer sexual decisions. The Conflict Model of Decision Making is presented and discussed as a framework for enhanced understanding of safer sexual decision making by adolescent women. PMID:12936697

    2014-10-01

    Previous studies have found that males are more upset over sexual infidelity than females whereas females are more upset over emotional infidelity than males. We hypothesized that such sex differences are explained by explicit sexual imagery by males. The hypothesis was tested in a laboratory using vivid infidelity scenarios and photographs to induce detailed and sexually oriented imagery of a partner's infidelity. In the main experiment, participants included 64 males and 64 females who were currently in committed relationships. The results showed that participants became more upset when they imagined sexual infidelity vividly and realistically than when they did not and there were no significant sex differences in jealousy found when sexual infidelity was imagined in this matter. Overall, our findings suggested that the sex differences in jealousy resulted from males' tendency to imagine sexual infidelity more vividly than females. PMID:24647817

    Using the Integrated Model of Behavioral Prediction, this study examines the effects of exposure to sexual content on television by genre, specifically looking at comedy, drama, cartoon, and reality programs, on adolescents’ sex-related cognitions and behaviors. Additionally, we compared the amount and explicitness of sexual content as well as the frequency of risk and responsibility messages in these four genres. Findings show that overall exposure to sexual content on television was not related to teens’ engagement in sexual intercourse the following year. When examined by genre, exposure to sexual content in comedies was positively associated while exposure to sexual content in dramas was negatively associated with attitudes regarding sex, perceived normative pressure, intentions, and engaging in sex one year later. Implications of adolescent exposure to various types of content and for using genre categories to examine exposure and effects are discussed. PMID:24187395

  1. Detecting sexual conflict and sexually antagonistic coevolution

    PubMed Central

    Rowe, Locke; Day, Troy

    2006-01-01

    We begin by providing an operational definition of sexual conflict that applies to both inter- and intralocus conflict. Using this definition, we examine a series of simple coevolutionary models to elucidate fruitful approaches for detecting interlocus sexual conflict and resultant sexually antagonistic coevolution. We then use published empirical examples to illustrate the utility of these approaches. Three relevant attributes emerge. First, the dynamics of sexually antagonistic coevolution may obscure the conflict itself. Second, competing models of inter-sexual coevolution may yield similar population patterns near equilibria. Third, a variety of evolutionary forces underlying competing models may be acting simultaneously near equilibria. One main conclusion is that studies of emergent patterns in extant populations (e.g. studies of population and/or female fitness) are unlikely to allow us to distinguish among competing coevolutionary models. Instead, we need more research aimed at identifying the forces of selection acting on shared traits and sexually antagonistic traits. More specifically, we need a greater number of functional studies of female traits as well as studies of the consequences of both male and female traits for female fitness. A mix of selection and manipulative studies on these is likely the most promising route. PMID:16612887

    Spatially explicit greenhouse gas inventories are gaining in importance as a tool for policy makers to plan and control mitigation measures, and are a required input for atmospheric models used to relate atmospheric concentration measurements with upstream sources. In order to represent the high spatial heterogeneity in Switzerland, we compiled the national methane inventory into a 500 m x 500 m cadaster. In addition to the anthropogenic emissions reported to the United Nation Framework Convention on Climate Change (UNFCCC), we also included natural and semi-natural methane fluxes, i.e., emissions from lakes and reservoirs, wetlands, wild animals as well as forest uptake. Methane emissions were disaggregated according to geostatistical information about source location and extent. In Switzerland, highest methane emissions originate from the agricultural sector (152 Gg CH4 yr-1), followed by emissions from waste management (16 Gg CH4 yr-1) with highest contributions from landfills, and the energy sector (13 Gg CH4 yr-1) with highest contributions from the distribution of natural gas. Natural and semi-natural emissions only add a small amount (< 5%) to the total Swiss emissions. For validation, the bottom-up inventory was evaluated against methane concentrations measured from a small research aircraft (METAIR-DIMO) above the Swiss Plateau on 18 different days from May 2009 to August 2010 over. Source sensitivities of the air measured were determined by backward runs of the Lagrangian particle dispersion model FLEXPART-COSMO. Source sensitivities were multiplied with the methane inventory to derive simulated methane concentration time series. While the pattern of the variations can be reproduced well for some flight days (correlation coefficient up to 0.75), the amplitude of the variations for the simulated time series is underestimated by at least 20% suggesting an underestimation of CH4 emissions by the inventory, which is also concluded from inverse estimation using a Bayesian approach.

    2013-08-01

    We report a case study of a semantic dementia patient, whose episodic memory consolidation was tested over a 2-month period. The results reveal that despite early retention of information, the patient lost all explicit information of the newly learnt material after 2 weeks. By contrast, he retained implicit word information even after a 4-week delay. These findings highlight the critical time window of 2-4 weeks in which newly learnt information should be re-encoded in rehabilitations studies. The results also indicate that learnt information can be still accessed with implicit retrieval strategies when explicit retrieval fails. PMID:22788676

    In the conventional optics, the pseudo-Brewster angle (PBA) mainly depends on the permittivity of the optical materials. However, the recent development of metamaterials in the optical wavelength has put magnetic permeability on equal footing. Thus, the conventional PBA needs to be revisited to include the permeability for metamaterial applications in the optical region. By taking into account the loss and anisotropy of the metamaterials, we present the explicit expression of PBA in terms of complex permittivity and permeability through rigorous analysis. Based on the explicit expression, some interesting features and potential applications of the PBA are discussed.

    2015-01-01

    This study examined sexual risk behaviors and sexual refusal assertiveness in relationship to child sexual abuse (CSA), emotion dysregulation, and adult sexual revictimization. Path analyses of 1,094 survivors who had sex in the past year were done to examine sexual risk behavior, and sexual refusal assertiveness mediational pathways by which CSA severity and emotion dysregulation may affect revictimization over one year in adult female sexual assault survivors. Exchanging sex for money and sexual refusal assertiveness were significantly associated with emotion dysregulation, whereas exchanging sex for money, and not sexual refusal assertiveness, was only significantly related to CSA severity. Both exchanging sex for money and sex refusal assertiveness mediated the relationship between emotion dysregulation and adult sexual revictimization. Exchanging sex for money mediated the CSA severity-revictimization relationship. These findings demonstrate the importance of considering both risky and protective sexual behaviors in research and prevention programming that address sexual revictimization in women. PMID:25942287

    Ten percent of 362 headache sufferers reported sexual arousal during migraine attack. Clinical investigations on sexuality in 16 headache sufferers, according to some studies showing correlations between idiopathic headache and sexual behavior, were performed. Patients responding by questionnaire listed each sexual experience, headache attack, and number of sleeping hours every day for 1 month. In both men and women, the number of coiti, erotic dreams, and sleeping hours were similar in headache sufferers and controls, while the frequency of masturbation was significantly reduced in the former. Sexual excitement and fantasies appeared more often in female headache sufferers than in controls, while the opposite occurred in the male group. Among the clinical analogies between the crises of migraine and morphine abstinence, sexual arousal may be included. PMID:7054999

    Twenty-six, eugonadal men between the ages of 18 and 27 participated in this investigation of the relationship between sexual arousal, testosterone (T) levels, and the processing of sexual information. At each of the two test sessions, subjects gave a blood sample, listened to an erotic or neutral priming audiotape, and completed a dichotic listening task designed to assess selective attention for sexual stimuli. Subjective levels of sexual arousal to the audiotape and sexual attitudes and sexual experience were assessed by self-report measures. Contrary to our hypothesis, there was no relationship between levels of free T and the strength of the selective attention bias for sexual stimuli. However, men who were more distracted by the sexual material in the task reported higher levels of sexual arousal to erotic imagery than men who were less distracted by the sexual material in the task (P less than 0.01). Moreover, men who were more sexually aroused by the erotic audiotape made significantly less shadowing errors in the erotic prime condition then they did during the neutral prime condition (P less than 0.05). There was a negative association between T and shadowing errors in the erotic prime condition (P less than 0.05). These results suggest that lower thresholds for sexual arousal are associated with a greater bias to attend to sexual information and that T may have effects on cognitive-motivational aspects of sexual behavior by enhancing attention to relevant stimuli.

  8. Sexual morality of Christianity.

    PubMed

    Runkel, G

    1998-01-01

    After discussing the origin of religion, functions of religion, and the construction of meaning by religion, the author focuses on the connection between religion and anxiety. The permanent anxiety in religion is determined by guilt feelings that arise for example from the violation of norms in the area of sexuality. In a religion at enmity with sexuality, such as Christianity, the satisfaction of sexual desires is considered bad and sinful; the permanent production of anxiety and a guilty conscience are the result of it. Christian sexual suppression leads to the propagation of asceticism as the taming of corrupt sensuality that only religious virtuosi can maintain. One result of asceticism is celibacy, although passages from the Bible demand monogamy for bishops without prohibiting celibacy. In Catholicism, celibacy institutionalizes the enmity with sexuality and causes a permanent depreciation of real sexuality in favor of one projected onto the mother church and the Virgin Mary. A further consequence of asceticism is the reduction of sexuality to reproduction. In the section about the factual consequences of Christian sexual morality, the author connects sexual instinctual gratification with religious affiliation on the basis of an analysis of the sexual behavior of Germans. The weekly frequency rate of sexual intercourse amounts to 3.1 with male and female nondenominationals, 2.6 with Protestants, and 2.3 with Catholics; 39% of nondenominational men, 20% of Protestant men, and 12% of Catholic men in Germany use condoms. The connection of religion and aggression is empirically significant as well. The religiously most active men feel more inclined to use aggression to reach sexual goals than religiously indifferent ones. PMID:9611690

    Sexual health encompasses 'sexual development and reproductive health, as well as the ability to develop and maintain meaningful interpersonal relationships; appreciate one's own body; interact with both genders in respectful and appropriate ways; express affection, love and intimacy in ways consistent with one's own values'. The 2008 WHO Consensus Statement additionally noted that 'responsible adolescent intimate relationships' should be 'consensual, non-exploitative, honest, pleasurable and protected against unintended pregnancy and STDs if any type of intercourse occurs'. Young people (YP) must, therefore, be able to access sexual health information and services that meet their needs. For most YP, interest in sexual activity begins with puberty, and this is associated with increasingly sexualised behaviour, including exploration of themselves and others. Most YP find this a confusing time, and so it is important that health professionals are able to offer advice regarding the wide range of sexual health issues, including sexuality, choice of partner, contraception, risk and management of sexually transmitted infections (STI) in a confident and approachable manner. YP have never had so much choice or information available to them, and this can be confusing for them. There is good evidence that YP who get information from their parents are likely to initiate sexual activity later than their peers who access information from their friends. However, there is also evidence that some YP would prefer to get sexual health information from health professionals. It is therefore imperative that all health professionals who see YP have an awareness of sexual health issues, and know where to signpost YP should they need more specialist sexual health advice and/or treatment. Where appropriate, one-to-one sexual health advice should be provided to YP on how to prevent and get tested for STIs, and how to prevent unwanted pregnancies. Advice should also be given on all methods of reversible contraception, including long-acting reversible contraception, emergency contraception and other reproductive issues. PMID:22983512

The material models implemented are: elastic, orthotropic elastic, kinematic/isotropic plasticity, thermoelastoplastic, soil and crushable foam, linear viscoelastic, Blatz-Ko rubber, high explosive burn, hydrodynamic without deviatoric stresses, elastoplastic hydrodynamic, temperature-dependent elastoplastic, isotropic elastoplastic, isotropic elastoplastic with failure, soil and crushable foam with failure, Johnson/Cook plasticity model, pseudo TENSOR geological model, elastoplastic with fracture, power law isotropic plasticity, strain rate dependent plasticity, rigid, thermal orthotropic, composite damage model, thermal orthotropic with 12 curves, piecewise linear isotropic plasticity, inviscid two invariant geologic cap, orthotropic crushable model, Moonsy-Rivlin rubber, resultant plasticity, closed form update shell plasticity, and Frazer-Nash rubber model. The hydrodynamic material models determine only the deviatoric stresses. Pressure is determined by one of 10 equations of state including linear polynomial, JWL high explosive, Sack `Tuesday` high explosive, Gruneisen, ratio of polynomials, linear polynomial with energy deposition, ignition and growth of reaction in HE, tabulated compaction, tabulated, and TENSOR pore collapse. DYNA3D generates three binary output databases. One contains information for complete states at infrequent intervals; 50 to 100 states is typical. The second contains information for a subset of nodes and elements at frequent intervals; 1,000 to 10,000 states is typical. The last contains interface data for contact surfaces.

    1992-01-01

    A unified finite element algorithm is developed which is applicable to a wide range of problems of fluid mechanics without recourse to artificial, empirically determined factors. In its explicit form, the algorithm is similar to the Taylor-Galerkin scheme and is easily adopted to standard codes. The scheme proposed here possesses sufficient natural balancing diffusion and thus reduces and sometimes eliminates the need for special 'shock capturing' diffusion. The efficiency of the algorithm is demonstrated using several examples ranging from incompressible through transonic regions to supersonic flows.

    Background Adolescence is a period when the individual is vulnerable and exposure to sexually implicit/explicit programs on television and internet can influence their sexual behaviour and make them more permissive towards premarital sex, which is known to influence their academic performance. This can be modified by parental discussion on these matters with their children. There have been only few studies from India that have explored such issues therefore this study aimed to explore the impact of television, internet and parental discussion on sexual activity and academic performance. Methods This study was conducted in two co-education schools using a self reporting questionnaire administered to students of class IX–XII. This study evaluated the relation of academic performance, exposure to media such as television & internet to sexual activity & academic performance of the students and the role of parental discussion on these. Results The study sample size was 586. There is no significant association between the number of hours of watching television per day and academic performance as measured by marks in examinations. Significant positive association was found among boys between sexual contact and average score in academics & unsupervised use of internet. In both genders a significant positive association was found between those watching English serials, movies and increased chances of indulging in sexual activity while a negative relation with those watching Cartoons. There is no significant difference in occurrence of sexual contact in those who discussed sexual matters with parents and those who did not. Conclusion This being first of it's kind of study from India and a cross sectional study, further prospective and detailed studies are warranted to delineate the interaction of media, parental discussion, academic performance and sexual activity.

    "Risky sexual behavior" accounts for the majority of new HIV infections regardless of gender, age, geographic location, or ethnicity. The phrase, however, refers to a relatively nebulous concept that hampers development of effective sexual health communication strategies. The purpose of this paper was to propose development of a shared conceptual understanding of "risky sexual behavior." We reviewed multidisciplinary HIV/AIDS literature to identify definitions of risky sexual behavior. Both the linguistic components and the social mechanisms that contribute to the concept of risky sexual behaviors were noted. Risky sexual behavior was often defined in a subjective manner in the literature, even in the scientific research. We urge a paradigm shift to focus on explicit behaviors and the social context of those behaviors in determining HIV risk. We also propose a new definition that reduces individual biases and promotes a broader discussion of the degree of sexual risk across a diversity of behavioral contexts. Sexual health professionals can strengthen practice and research initiatives by operating from a concise working definition of risky sexual behavior that is broadly transferable and expands beyond a traditional focus on identity-based groups.

  9. Functional differences between statistical learning with and without explicit training.

    Humans are capable of rapidly extracting regularities from environmental input, a process known as statistical learning. This type of learning typically occurs automatically, through passive exposure to environmental input. The presumed function of statistical learning is to optimize processing, allowing the brain to more accurately predict and prepare for incoming input. In this study, we ask whether the function of statistical learning may be enhanced through supplementary explicit training, in which underlying regularities are explicitly taught rather than simply abstracted through exposure. Learners were randomly assigned either to an explicit group or an implicit group. All learners were exposed to a continuous stream of repeating nonsense words. Prior to this implicit training, learners in the explicit group received supplementary explicit training on the nonsense words. Statistical learning was assessed through a speeded reaction-time (RT) task, which measured the extent to which learners used acquired statistical knowledge to optimize online processing. Both RTs and brain potentials revealed significant differences in online processing as a function of training condition. RTs showed a crossover interaction; responses in the explicit group were faster to predictable targets and marginally slower to less predictable targets relative to responses in the implicit group. P300 potentials to predictable targets were larger in the explicit group than in the implicit group, suggesting greater recruitment of controlled, effortful processes. Taken together, these results suggest that information abstracted through passive exposure during statistical learning may be processed more automatically and with less effort than information that is acquired explicitly.

    Sustaining and strengthening the ability of the elderly to continue their sexual needs can be realized as part of improving their quality of life, health and well-being. There is no age at which ends the expression of sexuality and intimacy. Through education, quality of life and advances in medicine, the average life expectancy is still increasing. Sexual activity of older people society usually describe using pejorative terms as an inappropriate, bizarre or obscene, but these labels are different than reality. Hormonal changes and other physiological changes associated with aging affect sexual interest. Erectile dysfunction is a problem in men increasing with age. There is no evidence that premature ejaculation is more common in older age. Cross-sectional studies showed no difference in sexual dysfunction between older and younger women. Age is not a barrier to sexually transmitted diseases. The most common pathogenetic factors for male erectile dysfunction are vascular diseases. In women, the most important symptoms of sexual dysfunction are lack of emotional wellbeing and a sense of intimacy during sexual intercourse. PMID:25815611

    2010-08-01

    The main aim of this study was to examine whether an assessment of implicit bullying attitudes could add to the prediction of bullying behavior after controlling for explicit bullying attitudes. Primary school children (112 boys and 125 girls, M age = 11 years, 5 months) completed two newly developed measures of implicit bullying attitudes (a general Implicit Association Test on bullying and a movie-primed specific IAT on bullying), an explicit bullying attitude measure, and self reported, peer reported, and teacher rated bullying behavior. While explicit bullying attitudes predicted bullying behavior, implicit attitudes did not. However, a significant interaction between implicit and explicit bullying attitudes indicated that in children with relatively positive explicit attitudes, implicit bullying attitudes were important predictors of bullying behavior. Theoretical and practical implications are discussed. PMID:20352324

    Background: One of negative and influential factor to chronic diseases is creation of sexual problems in the couple's sexual relationship. Sexual health is one of the most important factor in Sexual and marital satisfaction. Objective: This study aims to compare the relationship between couple burnout, sexual assertiveness, and sexual dysfunctional beliefs in women with diabetic and non-diabetic husbands. Materials and Methods: This cross sectional descriptive study was a causal comparative one. The research plan was derived from the master’s dissertation for family counseling in Shahid Beheshti University which was done during 2011-2012 in Tehran, Iran. Totally 200 participants were included in this study; 100 participants were women with diabetic husbands and the others were women with non-diabetic husbands. These participants were selected by purposeful sampling method. Data were collected using personality traits and demographic characteristics’ questionnaire, couple burnout Measure, Hulbert index of sexual assertiveness and sexual dysfunctional beliefs Questionnaire. Results: Results of the multi-variable analysis of variance indicated that there was a significant difference between couple burnout, sexual assertiveness, and sexual dysfunctional beliefs in women with diabetic and non-diabetic husbands. Women with non-diabetic husbands had a higher mean score in sexual assertiveness factor compared to women with diabetic husbands, whereas in couple burnout and sexual dysfunctional beliefs factors, women with diabetic husbands had a higher mean score. Conclusion: It seems that one of the most important factors which influences and increases couple burnout, increases wrong sexual beliefs regarding sexual function, and decreases sexual assertiveness in women is their husbands’ sexual dysfunction. In fact, women whose husbands suffer from chronic diseases such as diabetes (which results in sexual dysfunction) have lower sexual assertiveness and higher couple burnout and sexual dysfunctional beliefs compared with other women.

    Sexuality is an essential aspect of quality of life. Nevertheless, sexual intercourse is physically challenging and leads to distinct changes in blood pressure, heart, and respiratory rate that may lead to vital complications. We present a case report of a 22-year-old female suffering from subarachnoid hemorrhage after sexual intercourse. The patient was immediately transported to hospital by emergency medical services and, after diagnosis, transferred to a tertiary hospital with neurosurgical expertise but died within 24 hours. After postcoital headaches, subarachnoid hemorrhage is the second most common cause of neurological complications of sexual intercourse and therefore patients admitted to an emergency department with headache after sexual intercourse should always be carefully evaluated by cerebral imaging.

    NASA Langley Research Center has successfully developed an electron beam freeform fabrication (EBF3) process, a rapid metal deposition process that works efficiently with a variety of weldable alloys. The EBF3 process can be used to build a complex, unitized part in a layer-additive fashion, although the more immediate payoff is for use as a manufacturing process for adding details to components fabricated from simplified castings and forgings or plate products. The EBF3 process produces structural metallic parts with strengths comparable to that of wrought product forms and has been demonstrated on aluminum, titanium, and nickel-based alloys to date. The EBF3 process introduces metal wire feedstock into a molten pool that is created and sustained using a focused electron beam in a vacuum environment. Operation in a vacuum ensures a clean process environment and eliminates the need for a consumable shield gas. Advanced metal manufacturing methods such as EBF3 are being explored for fabrication and repair of aerospace structures, offering potential for improvements in cost, weight, and performance to enhance mission success for aircraft, launch vehicles, and spacecraft. Near-term applications of the EBF3 process are most likely to be implemented for cost reduction and lead time reduction through addition of details onto simplified preforms (casting or forging). This is particularly attractive for components with protruding details that would require a significantly large volume of material to be machined away from an oversized forging, offering significant reductions to the buy-to-fly ratio. Future far-term applications promise improved structural efficiency through reduced weight and improved performance by exploiting the layer-additive nature of the EBF3 process to fabricate tailored unitized structures with functionally graded microstructures and compositions.

    The current study examined sexual victimization and two barriers to young women's sexual assertiveness: fear of sexual powerlessness and cognitive emotion dysregulation. College women (N = 499) responded to surveys and indicated that fear of sexual powerlessness and, to a lesser extent, cognitive emotion dysregulation were barriers to sexual assertiveness. Compared with nonvictims, sexually victimized women had greater problems with sexual assertiveness, fear of sexual powerlessness, and cognitive emotion dysregulation. Among victims, fear of sexual powerlessness and emotion dysregulation interacted to impede sexual assertiveness. Findings support targeting identified barriers in interventions to improve sexual assertiveness and reduce risk for unwanted sexual experiences and sexual victimization. PMID:24379216

    Most time-domain, wave problems in geophysics are intractable by classical analysis methods, due principally to non-separability and to a lesser extent material nonlinearity. Therefore, discrete numerical solutions are often necessary for the simulation of realistic models. Applications in 2-D and 3-D geophysical modeling are the subject of this paper, particularly as solved on a CRAY-2 supercomputer. Implementation and performance differences between earlier CRAYs and the CRAY-2 are described, including the discrepancy between scalar fetch and vector processing speeds. Explicit finite element solvers are applied to applications involving 2-D simulation of a seismic refraction experiment across the state of Maine, 3-D simulation of near-source scattering experiments, and both linear and nonlinear axisymmetric source simulation. Results show that the CRAY-2 allows cost-effective 2-D simulations of truly large-scale models, but only begins to be effective in 3-D for models of interest in geophysics. The large memory (256 megawords) is adequate but a speed increase of at least an order of magnitude is necessary for cost-effective 3-D. True multiprocessor capability (rather than 'multi-computer') provides an alternative to raw speed but involves another set of difficulties.

    The understanding of phase behavior of copolymer brushes is of fundamental importance for the design of smart materials. In this paper, we have performed classical density functional theory calculations to study diblock copolymer brushes (A-B) in an explicit solvent which prefers the A block to B block. With increasing B-block length (NB), we find a structural transition of the copolymer brush from mixed to collapsed, partial-exposed, and exposed structure, which is qualitatively consistent with experiments. The phase transitions are attributed to the interplay between entropic cost of folding copolymer brushes and enthalpic effect of contact between unlike components. In addition, we examine the effect of different parameters, such as grafting density (?g), the bottom block length (NA), and the chain length of solvent (NS) on the solvent response of copolymer brushes. The transition chain length (NB) increases with decreasing ?g and NA, and a smaller solvent molecule makes the collapsed structure less stable due to its lower penetration cost. Our results provide the insight to phase behavior of copolymer brushes in selective solvents from a molecular view.

    Research has shown that gay male couples’ sexual agreements may affect their risk for HIV. Few U.S. studies have collected dyadic data nationally from gay male couples to assess what sexual behaviors they allow to occur by agreement type and the sequence of when certain behaviors occur within their relationships. In our cross-sectional study, dyadic data from a convenience sample of 361 male couples were collected electronically throughout the U.S. by using paid Facebook ads. Findings from our study revealed that couples discussed their HIV status before having UAI, but established their agreement some time after having UAI. About half of the couples (N = 207) concurred about having an agreement. Among these couples, 58% concurred about explicitly discussing their agreement, 84% concurred about having the same type of agreement, and 54% had both men adhering to it. A variety of sexual behaviors were endorsed and varied by agreement type. Concordance about aspects of couples’ agreements varied, suggesting the need to engage couples to be more explicit and detailed when establishing and communicating about their agreements. The allowed behaviors and primary reasons for establishing and breaking sexual agreements further highlight the need to bolster HIV prevention for gay male couples. PMID:23514544

    2009-02-01

    Sexuality is innate within all women to a greater or lesser extent, and is affected by a number of extrinsic factors that occur in the menopausal transition. Assessing hormone status is difficult as evidence exists that sex hormones may differ between ethnic groups, and that bio-assays may be insensitive at lower testosterone levels. Data are available on the prevalence of female sexual dysfunction, but results from cross-sectional studies differ from those of longitudinal studies. The original traditional models of human sexual response have been challenged, and new models have been defined which show more complex interaction between intrinsic and extrinsic factors. Definitions of sexual dysfunction have been redefined. There are a limited number of randomized, placebo-controlled trials of drugs to improve sexual function. These include sildenafil citrate, tibolone and hormone replacement therapy. Randomized controlled trials on testosterone replacement in naturally and/or surgically menopausal patients with female sexual dysfunction have been criticized for a high placebo response rate and short duration. This chapter seeks to put sexuality into perspective and to define both function and dysfunction. PMID:19058763

    Sexting, or the exchange of sexually explicit material via Internet social-networking site or mobile phone, is an increasingly prevalent behavior. The study sought to (1) identify expectancies regarding sexting behaviors, (2) examine how demographics (i.e., gender, sexual identity, relationship status) might be differentially related to sexting expectancies and behaviors, and (3) examine whether these concurrent relationships are consistent with a theoretical causal model in which sexting expectancies influence sexting behaviors. The sample consisted of 278 undergraduate students (mean age=21.0 years, SD=4.56; 53.8% female; 76.3% caucasian). Factor analyses supported the validity and reliability of the Sextpectancies Measure (α=0.85-0.93 across subscales) and indicated two expectancy domains each for both sending and receiving sexts: positive expectancies (sexual-related and affect-related) and negative expectancies. Males reported stronger positive expectancies (F=4.64, p=0.03) while females reported stronger negative expectancies (F=6.11, p=0.01) about receiving sexts. There were also differences across relationship status regarding negative expectancies (F=2.25, p=0.05 for sending; F=4.24, p=0.002 for receiving). There were also significant effects of positive (F=45.98, p<0.001 for sending, F=22.42, p<0.001 for receiving) and negative expectancies (F=36.65, p=0.02 sending, F=14.41, p<0.001 receiving) on sexting behaviors (η(2) from 0.04-0.13). College students reported both positive and negative sextpectancies, although sextpectancies and sexting varied significantly across gender, race, sexual identity, and relationship status. Concurrent relationships were consistent with the causal model of sextpectancies influencing sexting behaviors, and this study serves as the first test of this model, which could inform future prevention strategies to mitigate sexting risks.

    Background: Infertility is a serious problem in a couple's life that affects their marriage relationships. So, dissatisfaction with sexual function resulting from interpersonal problems is common among these couples. This qualitative study aimed to explore the experiences of infertile women in their sexual life. Materials and Methods: This is a qualitative study with a phenomenological approach. The participants were 20 infertile women referring to the health care centers and infertility clinics of Isfahan and were selected through purposive sampling. Data were collected by tape recording of deep interviews and analyzed by Colaizzi's method. Results: Analysis of the participants’ experiences led to five main concepts: “Disturbed in femininity-body image,” “discouragement of sexual relations,” “sacrifice of sexual pleasure for the sake of getting pregnant,” “confusion in sexual relation during infertility treatment,” and “striving to protect their marriage.” Conclusions: Findings revealed that infertility affects women's different aspects of sexual life, especially disturbance in femininity-body image and sexual reluctance. With regard to women's willingness to protect their matrimonial life and prevent sexual trauma as a destroying factor for their family's mental health, it seems sexual counseling is necessary for infertile couples.

    The construction of the explicit algebraic-polynomial expressions for the nonmultiplicity-free orthonormal Clebsch-Gordan (Wigner) coefficients of SU(3)?U(2) is completed in the case of the paracanonical coupling scheme related with the explicit minimal biorthogonal systems by means of the Hecht or Gram-Schmidt process. The direct and inverse orthogonalization coefficients (the first of them being equivalent to the boundary orthonormal isofactors) are expressed, up to explicitly given multiplicative factors, in terms of the numerator and denominator polynomials related with the auxiliary A? function of Louck, Biedenharn, and Lohe that appears as a fragment of the denominator G-functions of canonical SU(3) tensor operators.

  16. Sexual selection and diversification: reexamining the correlation between dichromatism and speciation rate in birds.

    2014-11-01

    Theory predicts that sexual selection can serve as an important driver of speciation, but phylogenetic comparative analyses have failed to demonstrate a consistent effect of sexual selection on species richness at macroevolutionary scales. Sexual dichromatism in birds is an example of a phenotypic trait that is hypothesized to reflect the intensity of sexual selection, yet previous studies have reached ambiguous conclusions regarding its role in promoting species diversification. Here, we revisit this problem by pairing published spectrophotometer estimates of plumage dichromatism in the bird-visible range with a newly developed method for modeling speciation rates on phylogenetic trees that explicitly accounts for diversification rate variation through time and among clades. We find little evidence linking dichromatism to speciation across birds, using several measures of dichromatism and macroevolutionary diversification. These results suggest that sexual dichromatism plays a limited role in determining speciation rates at macroevolutionary scales in birds. PMID:25325752

    The sexual behaviours placing an individual at risk for HIV infection are those also placing him/her at risk for gonorrhoea, syphilis, hepatitis B, chlamydia and unplanned pregnancy. This article proposes that approaches to HIV prevention must be included within a broad context of human sexuality. To address disease prevention in the absence of including people's relationships, social, behavioural and emotional needs is futile. Compartmentalization, denial of risk by various populations, and societal barriers are all factors to be overcome in the fight against HIV transmission. Specific strategies involved in a comprehensive approach are outlined under the categories of predisposing, enabling and reinforcing factors contributing to healthy sexual behaviour. PMID:8481861

    A viscoplastic constitutive model was formulated to model the high strain-rate expansion of thin cylindrical shells subjected to internal explosive detonations. This model provides insight into the development of plastic instabilities, which occur on the surface of the shells prior to failure. The effects of shock heating and damage in the form of microvoid nucleation, growth, and coalescence were incorporated using the Johnson-Cook strength model with the Mie-Grueneisen equation of state and a modified Gurson yield surface. This model was implemented into ABAQUS/Explicit as a user material subroutine. A cylindrical copper shell was modeled using both axisymmetric and plane strain elements. The high explosive material inside of the cylinder was simulated using the high explosive burn model in ABAQUS/Explicit. Two experiments were conducted involving explosive-filled, copper cylinders and good agreement was obtained between the numerical results and experimental data.

    Polysomnographic recordings were obtained in 10 subjects (5 men and 5 women) for three conditions: following masturbation with orgasm, following masturbation without orgasm, and after reading neutral material. The analysis of several sleep parameters did not reveal any effect of masturbation on sleep. These results suggest that physiological changes that occur during masturbation, with or without orgasm, have no major effect on sleep organization. Other factors associated with sexual activity and potentially responsible for sleepiness after orgasm are discussed, and further strategies to study the interrelationship of sexual activity and sleep are proposed.

    2014-01-01

    The gender-based response to HIV in sub-Saharan Africa has tended to reinforce normative stereotypes of women as subordinated, passive and powerless victims, in particular in sexual relations. However, based on qualitative data from Rwanda, this paper argues that such conceptualisations fail to recognise that while women do comply with prevalent social norms, they also challenge these norms and sex becomes a domain in which they can exert power. Female sexuality and sexual gratification - acknowledged and valued by women as well as men - play a pivotal role in the Rwandese mode of sexual intercourse. This provides women a central position in sexual relations, which affords them sexual power. Recognising their sexuality as a resource and drawing upon this 'sexual capital', women are active social agents who have the capacity to manipulate and challenge male dominance in a deliberate strategy both to practice safer sex and to access decision-making power and material resources. This suggests that inherent in sexual relations is a potential for the empowerment of women and the transformation of gender relations. PMID:23895629

    Sexual scripts are widely shared gender and culture-specific guides for sexual behavior with important implications for HIV prevention. Although several qualitative studies document how sexual scripts may influence sexual risk behaviors, quantitative investigations of sexual scripts in the context of sexual risk are rare. This mixed methods study involved the qualitative development and quantitative testing of the Sexual Scripts Scale (SSS). Study 1 included qualitative semi-structured interviews with 30 Black heterosexual men about sexual experiences with main and casual sex partners to develop the SSS. Study 2 included a quantitative test of the SSS with 526 predominantly low-income Black heterosexual men. A factor analysis of the SSS resulted in a 34-item, seven-factor solution that explained 68% of the variance. The subscales and coefficient alphas were: Romantic Intimacy Scripts (α = .86), Condom Scripts (α = .82), Alcohol Scripts (α = .83), Sexual Initiation Scripts (α = .79), Media Sexual Socialization Scripts (α = .84), Marijuana Scripts (α = .85), and Sexual Experimentation Scripts (α = .84). Among men who reported a main partner (n = 401), higher Alcohol Scripts, Media Sexual Socialization Scripts, and Marijuana Scripts scores, and lower Condom Scripts scores were related to more sexual risk behavior. Among men who reported at least one casual partner (n = 238), higher Romantic Intimacy Scripts, Sexual Initiation Scripts, and Media Sexual Socialization Scripts, and lower Condom Scripts scores were related to higher sexual risk. The SSS may have considerable utility for future research on Black heterosexual men's HIV risk. PMID:24311105

    An a posteriori error estimator is developed for the eigenvalue analysis of three-dimensional heterogeneous elastic structures. It constitutes an extension of a well-known explicit estimator to heterogeneous structures. We prove that our estimates are independent of the variations in material properties and independent of the polynomial degree of finite elements. Finally, we study numerically the effectivity of this estimator on several model problems.

  4. Beyond sex allocation: the role of mating systems in sexual selection in parasitoid wasps

    2015-01-01

    Despite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked. For instance, parasitoid mating systems have typically been studied in terms of how mating structure affects sex allocation. In the past decade, however, some studies have sought to address sexual selection in the parasitoid wasps more explicitly and found that, despite the lack of obvious secondary sexual traits, sexual selection has the potential to shape a range of aspects of parasitoid reproductive behaviour and ecology. Moreover, various characteristics fundamental to the parasitoid way of life may provide innovative new ways to investigate different processes of sexual selection. The overall aim of this review therefore is to re-examine parasitoid biology with sexual selection in mind, for both parasitoid biologists and also researchers interested in sexual selection and the evolution of mating systems more generally. We will consider aspects of particular relevance that have already been well studied including local mating structure, sex allocation and sperm depletion. We go on to review what we already know about sexual selection in the parasitoid wasps and highlight areas which may prove fruitful for further investigation. In particular, sperm depletion and the costs of inbreeding under chromosomal sex determination provide novel opportunities for testing the role of direct and indirect benefits for the evolution of mate choice.

  5. Moderators of the Relationship between Implicit and Explicit Evaluation

    PubMed Central

    2005-01-01

    Automatic and controlled modes of evaluation sometimes provide conflicting reports of the quality of social objects. This paper presents evidence for four moderators of the relationship between automatic (implicit) and controlled (explicit) evaluations. Implicit and explicit preferences were measured for a variety of object pairs using a large sample. The average correlation was r = .36, and 52 of the 57 object pairs showed a significant positive correlation. Results of multilevel modeling analyses suggested that: (a) implicit and explicit preferences are related, (b) the relationship varies as a function of the objects assessed, and (c) at least four variables moderate the relationship – self-presentation, evaluative strength, dimensionality, and distinctiveness. The variables moderated implicit-explicit correspondence across individuals and accounted for much of the observed variation across content domains. The resulting model of the relationship between automatic and controlled evaluative processes is grounded in personal experience with the targets of evaluation. PMID:16316292

    The study aimed to identify implicit and explicit processes involved in reporting the sexual attractiveness of photographs of the same pubescent girls labeled as either under or within the age of sexual consent in the UK, women, and men. In two studies, 53 and 70 heterosexual men (M age 25.2 and 31.0 years) rated the sexual attractiveness of photographs in each category presented via computer [seeing target photographs of girls labeled as either under- (14-15 years) or within the age of consent (16-17 years)], using a 7-point response box. Ratings in Study 1 were in response to a question asking participants to rate how sexually attractive the person in each photograph was. In Study 2, participants rated how sexually attractive they personally found the target. Response times were also recorded. Several findings were replicated in both studies (although the strength of findings differed). Mean ratings of the sexual attractiveness of the underage girls were lower than those of overage girls and women. In addition, correlations revealed significantly longer responding times when "underage" girls (and men) were rated as more highly sexually attractive. No such relationship emerged with the same girls labeled within the age of consent or women. Overall, these data suggest that men find pubescent girls identified as being under the age of consent sexually attractive, but inhibit their willingness to report this; the greater the attraction, the greater the inhibition.

    It is intented to show two apparently antithetic poles: Sexuality and Death, in fact interpenetrate themselves, disguising the fear of death, or the desire to die, Eros' world. Different expressions of culture are analyzed, especially the one known as The Profane Time, the time for work, which is characterized by the submission to interdicts (prohibitions) and, on the other hand, the Time for Joy or The Sacred Time, characterized by the transgression of such prohibitions. Its relationship with the interdicts'violations in the sexual as well as in the death arena is analyzed in order to connect the human being's fear in the presence of the unrestraint, the overflow and the abandonment of the time established for work that would imply free sexuality. The latter is connected with some conclusions that could be considered useful in the field of Sexual Therapies, with a certain critical look at the mechanist settlement applied to those treatments.

  3. Elderly Sexual Offenders.

    2016-04-01

    With the ever-aging population, the number of elderly sexual offenders are also on the rise. The courts and correctional system are increasingly faced with older individuals who have offended sexually. Previously, these older offenders were thought to be similar to younger sexual offenders. However, closer analysis suggests that many of these individuals pose a much lower risk to recidivate than the risk to recidivate of their younger counterparts. Still, an individualized approach to manage the risk of older offenders is required, as some may have particular risk factors relevant for their treatment and future stability, such as dementia or other mental health issues. Further, this population often has particular physical health issues and requires special consideration when being placed in the community. Assessment, treatment, and risk management in this special population of sexual offenders are discussed. PMID:26893232

  5. Prevalence of Sexual Dysfunctions

    2008-01-01

    Ten years of research that has provided data regarding the prevalence of sexual dysfunctions is reviewed. A thorough review of the literature identified 52 studies that have been published in the 10 years since an earlier review by Spector and Carey (1990). Community samples indicate a current prevalence of 0 - 3% for male orgasmic disorder, 0 - 5% for erectile disorder, and 0 - 3% for male hypoactive sexual desire disorder. Pooling current and 1-year figures provides community prevalence estimates of 7 - 10% for female orgasmic disorder and 4 - 5% for premature ejaculation. Stable community estimates of the current prevalence for the other sexual dysfunctions remain unavailable. Prevalence estimates obtained from primary care and sexuality clinic samples are characteristically higher. Although a relatively large number of studies have been conducted since Spector and Carey’s (1990) review, the lack of methodological rigor of many studies limits the confidence that can be placed in these findings.

  7. Detective magazines: pornography for the sexual sadist?

    Dietz, P E; Harry, B; Hazelwood, R R

    1986-01-01

    The origins of detective magazines can be traced to 17th and 18th century crime pamphlets and to 19th century periodicals that Lombroso called "really criminal newspapers." Content analysis of current detective magazines shows that their covers juxtapose erotic images with images of violence, bondage, and domination; that their articles provide lurid descriptions of murder, rape, and torture; and that they publish advertisements for weapons, burglary and car theft tools, false identification, and sexual aids. Six case histories of sexual sadists illustrate the use of these magazines as a source of fantasy material. We postulate that detective magazines may contribute to the development of sexual sadism, facilitate sadistic fantasies, and serve as training manuals and equipment catalogs for criminals. We recommend that detective magazines be considered during policy debates about media violence and pornography. PMID:3511174

    Young adults have high rates of sexually transmitted infections (STIs). Sexual minority youths’ risk for STIs, including HIV, is as high as or higher than sexual majority peers’. Sexual safety, while often treated as a single behavior such as condom use, can be best conceptualized as the result of multiple factors. We used latent class analysis to identify profiles based on ever-used sexual safety strategies and lifetime number of partners among 425 self-identified LGBTQ youth aged 14-19. Data collection took place anonymously online. We identified four specific subgroup profiles for males and three for females, with each subgroup representing a different level and type of sexual safety. Profiles differed from each other in terms of age and outness for males, and in outness, personal homonegativity, and amount of education received about sexual/romantic relationships for females. Youths’ sexual safety profiles have practice implications for sexuality educators, health care professionals, and parents. PMID:24011111

  9. Women's interest in visual sexual stimuli varies with menstrual cycle phase at first exposure and predicts later interest.

    2010-02-01

    This study investigated whether women's interest in visual sexual stimuli varied with their hormonal state. Viewing times of 30 women, 15 normal cycling (NC) and 15 oral contracepting (OC), to sexually explicit photos were measured at three different times. NC women were tested during their menstrual, periovulatory, and luteal phases, and OC women were tested at equivalent temporal intervals. Subjects viewed stimuli as long as desired, thus viewing time measured subject interest. Subjective ratings of stimulus sexual attractiveness were obtained on each test. There was no overall relationship between menstrual cycle phase and viewing time. However the participant's menstrual cycle phase during first exposure to sexual stimuli predicted subsequent interest in sexual stimuli during the next two tests. NC women who first viewed stimuli during their periovulatory phase looked longer at the sexual stimuli across all sessions than did women first tested in their luteal phase. OC women first exposed to the sexual stimuli during menstruation looked longer at the stimuli across all sessions than did OC women first exposed at other test phases. Neither current test phase nor initial cycle phase influenced subjective ratings. Women had increased interest in sexual stimuli across all sessions if first exposed to sexual stimuli when endogenous estrogens were most likely highest. These data suggest that women's interest in visual sexual stimuli is modulated by hormones such that the hormonal condition at first exposure possibly determines the stimuli's emotional valence, markedly affecting subsequent interest in sexual stimuli.

    Despite data indicating that child maltreatment (CM) in various forms is associated with adult sexual victimization among community women, few studies have explicitly explored how types of CM might relate to prison sexual victimization. Because little is known about how CM might give rise to prison sexual victimization, the present study also examined emotion dysregulation emanating from early abuse experiences as a potential mediator in the link between early CM and inmate-on-inmate prison sexual victimization. Approximately 168 incarcerated women completed self-report inventories assessing various types of childhood maltreatment, emotion dysregulation, and coerced or forced sexual experiences in prison. Nearly 77% of the sample endorsed experiencing at least one form of CM, with 64% of inmates reporting that they experienced two or more forms of CM. Approximately 9% of inmates reported sexual coercion and 22% reported a forced sexual experience in prison. Each form of CM was associated with prison sexual coercion; however, fewer associations emerged between CM and forced prison sexual experiences. Emotion dysregulation was found to mediate links between CM, particularly co-occurring CM, and sexual coercion in prison, but it was unrelated to forced prison sexual experiences. Implications are discussed. PMID:21987505

  12. The implications of sexual narcissism for sexual and marital satisfaction.

    2013-08-01

    There is theoretical reason to believe narcissism is associated with a number of sexual behaviors and outcomes that affect both sexual and relationship satisfaction. Nevertheless, research on the association between personality and behavior demonstrates that personality traits, such as narcissism, only predict behavior in domains that activate the components of the personality system. Given that global assessments of narcissism do not capture the extent to which the components of narcissism are activated in the sexual domain, we examined the extent to which the facets of a domain-specific measure of sexual narcissism accounted for the trajectories of own and partner sexual and marital satisfaction over the first five years of 120 new marriages. Three of the four facets of sexual narcissism (sexual exploitation, sexual entitlement, and low sexual empathy) were negatively associated with both trajectories. The fourth facet (sexual skill) was positively associated with both trajectories. Notably, sexual satisfaction mediated the effect of every facet of sexual narcissism on marital satisfaction. A global assessment of narcissism was not associated with either trajectory of satisfaction. These findings highlight (1) the importance of narcissistic tendencies for sexual processes, (2) the benefits of using domain-specific measures of personality in research on sexual behavior, and (3) the importance of examining the implications of the specific facets of personality constructs.

    Cervical infections with Neisseria gonorrhoeae, Chlamydia trachomatis, and Herpes simplex virus are some of the most common sexually transmitted infections. They are often asymptomatic, and therefore the patient is at risk of developing complications, such as pelvic inflammatory disease. It is important to recognize cervicitis, investigate it appropriately, and provide early treatment. Sexual partners must also be located and offered therapy to prevent re-infection in the index patient. PMID:21248969

    Spatially explicit population models are becoming increasingly useful tools for population ecologists, conservation biologists, and land managers. Models are spatially explicit when they combine a population simulator with a landscaped map that describes the spatial distribution of landscape features. With this map, the locations of habitat patches, individuals, and other items of interest are explicitly incorporated into the model, and the effect of changing landscape features on population dynamics can be studied. In this paper we describe the structure of some spatially explicit models under development and provide examples of current and future research using these models. Spatially explicit models are important tools for investigating scale-related questions in population ecology, especially the response of organisms to habitat change occurring at a variety of spatial and temporal scales. Simulation models that incorporate real-world landscapes, as portrayed by landscape maps created with geographic information systems, are also proving to be crucial in the development of management strategies in response to regional land-use and other global change processes. Spatially explicit population models will increase our ability to accurately model complex landscapes, and therefore should improve both basic ecological knowledge of landscape phenomena and applications of landscape ecology to conservation and management. 58 refs., 1 fig.

  15. Implicit and explicit memory in survivors of chronic interpersonal violence.

    2015-01-01

    We investigated the relationship of implicit and explicit memory to a range of symptoms in a sample of 27 women with exposure to chronic interpersonal violence (IPV). Participants viewed the first 3 letters ("stems") of trauma-related, general threat, and neutral words; valenced words were matched with neutral words with the same stem. Free recall and a word-stem completion task were used to test explicit and implicit memory, respectively. Participants exhibited increased implicit memory for trauma-related words as compared with both general threat words and neutral "match" words. They also showed increased explicit memory for both general threat and trauma-related words. Finally, although neither implicit nor explicit memory was correlated with PTSD symptoms, implicit memory for trauma-related words was significantly correlated with symptoms associated with ongoing IPV. Interpersonal sensitivity, hostility, and alexithymia were significantly correlated with implicit, but not explicit, memory for trauma words. Somatization, dissociation, and alexithymia were negatively correlated with explicit, but not implicit, memory for general-threat words. These findings suggest that memory processes in survivors of IPV are closely related to the symptom profile associated with complex trauma. Exploring memory processes in survivors of IPV may lend unique insight into the development and maintenance of the symptom profile associated with IPV. PMID:25793595

    Female sexual dysfunction is a common problem with detrimental effects on woman's quality of life. It also has an economical and societal impact. It is defined as disorders of sexual desire, arousal, orgasm, and sexual pain, which lead to personal distress. The etiology of sexual dysfunction is frequently multifactorial as it relates to general physical and mental well-being, quality of relationship, past sexual functioning, social class, education, employment, life stressors, personality factors, the presence of a sexual partner, and partner's age and health. It is very important to adopt the most efficient approach to gather information, and this may be achieved via standardized questionnaires or open-ended questions. Therapy should be tailored according to the patient's needs and may involve a multidisciplinary team approach including psychosexual counselor/sexologist/therapist and the physician. There is still more work needed to optimize the care of women with this problem. Priority should be given to international standardization and training of health care professionals. PMID:17973068

  17. Androgens and sexuality.

    PubMed

    Hutchinson, K A

    1995-01-16

    A review of the literature reveals that the endocrine determinants of female sexuality are complex and difficult to characterize. In adolescent males, free testosterone directly affects sexual motivation, with social factors exerting little or no effect. In adolescent girls, by contrast, societal and peer pressure play a pivotal role in the appearance of certain sexual behaviors. Throughout a woman's life, hormonal and psychosocial factors are critical influences. It is possible that cyclic patterns of testosterone are less important for female sexual behavior than the "tonic" effect of overall testosterone levels. Although the estrogen dependence of the vaginal epithelium--important for postmenopausal women--has been clearly established, the role of other hormonal factors and treatments, particularly those involving androgens, in human female sexual behavior remains enigmatic. The search for an understanding of these relationships is not merely an interesting academic exercise but is necessary to determine what role, if any, androgens may play in the treatment of sexual dysfunction during the female reproductive years.

    1991-10-01

    A 50 question survey was administered to 362 junior high school students in order to determine the level of sexual education. The objectives were to determine the themes of most interest to the students, to establish the precise participation of the school in sexual education, to define quality in teachers and to find possible differences in knowledge and attitudes according to school grade and sex. As expected, age but not sex, differed according to grades. Parents participated in the sexual education in their children in 50% of the sample; the high level of education of the majority of this group of parents will permit the development of additional programs for their participation in school related programs for sexual education. Sexual attitudes among students did not differ according to school grade. The percentage of responses about sexuality and reproduction that corresponded to materials in the curriculum was low; eighth grade students showed superior knowledge about theory, ninth grade students were superior in knowledge of more practical aspects. The principal sources of sexual education in this group were parents and teachers, 81% of the students reported having received some sexual education in the school, 51.4% as part of natural sciences course material and 12% as part of the eight grade course in social and human relations. We suggest a strategy of presenting progressively more complex materials of sexual education by grade in order to influence not only sexual attitudes but preventive sexual practices as well.

    Objective: To establish norms for sexual functioning questionnaire (SFQ) in Indian population. Materials and Methods: 100 male subjects, diagnosed with depressive disorder and currently in a state of clinical remission for a period of at least 4 weeks were evaluated on SFQ and Arizona Sexual Experience Questionnaire (ASEX). Result: By using receiver operating characteristics (ROC) curves a score of 14 was considered to be a cutoff for sexual dysfunction as per SFQ. This cutoff yielded a sensitivity of 91.7% and specificity of 86.4% for the detection of sexual dysfunction. The PPV of the instrument at this cutoff was 87%. Conclusion: A cutoff of 14 should be used to define sexual dysfunction as per SFQ. PMID:25336774

    Although experimental studies support that men generally respond more to visual sexual stimuli than do women, there is substantial variability in this effect. One potential source of variability is the type of stimuli used that may not be of equal interest to both men and women whose preferences may be dependent upon the activities and situations depicted. The current study investigated whether men and women had preferences for certain types of stimuli. We measured the subjective evaluations and viewing times of 15 men and 30 women (15 using hormonal contraception) to sexually explicit photos. Heterosexual participants viewed 216 pictures that were controlled for the sexual activity depicted, gaze of the female actor, and the proportion of the image that the genital region occupied. Men and women did not differ in their overall interest in the stimuli, indicated by equal subjective ratings and viewing times, although there were preferences for specific types of pictures. Pictures of the opposite sex receiving oral sex were rated as least sexually attractive by all participants and they looked longer at pictures showing the female actor's body. Women rated pictures in which the female actor was looking indirectly at the camera as more attractive, while men did not discriminate by female gaze. Participants did not look as long at close-ups of genitals, and men and women on oral contraceptives rated genital images as less sexually attractive. Together, these data demonstrate sex-specific preferences for specific types of stimuli even when, across stimuli, overall interest was comparable. PMID:18719987

    The mainstream mass media (television, magazines, movies, music, and the Internet) provide increasingly frequent portrayals of sexuality. We still know relatively little about how this content is used and how it affects sexual beliefs and behaviors. The few available studies suggest that the media do have an impact because the media keep sexual behavior on public and personal agendas, media portrayals reinforce a relatively consistent set of sexual and relationship norms, and the media rarely depict sexually responsible models. More longitudinal research, especially with early adolescents is needed to learn more about how media content is attended to, interpreted, and incorporated into developing sexual lives.

    In this article, I address the question of whether pedophilia in men can be construed as a male sexual orientation, and the implications for thinking of it in this way for scientific research, clinical practice, and public policy. I begin by defining pedophilia and sexual orientation, and then compare pedophilia (as a potential sexual orientation with regard to age) to sexual orientations with regard to gender (heterosexuality, bisexuality, and homosexuality), on the bases of age of onset, correlations with sexual and romantic behavior, and stability over time. I conclude with comments about the potential social and legal implications of conceptualizing pedophilia as a type of sexual orientation in males. PMID:22218786

    2007-01-01

    Internet pornography has been regarded as either stimulating sexual aggression and abuse or as serving as a safety valve. This controversy is an important issue in health, media and legal politics. According to empirical studies on pornography in general, soft-core pornography and nonviolent pornography can be regarded as harmless, whereas non-violent hard-core pornography and violent pornography may increase aggression. Individuals with a high risk for sexual aggression show more interest in violent pornography and are stimulated more strongly through such material. Two case histories illustrate the characteristics of internet pornography and "cybersex": easy access, anonymity, affordability, wide range and deviation of the material, unlimited market, blurring the borders between consumer and producer, interactive communication, space for experimenting between fantasy and in real-life behavior, virtual identities, easy contact between offender and victim or among offenders, and low risk of apprehension. The phenomenon of "sexual addiction" (or paraphilia- related disorder) is particularly relevant for the problematic use of internet pornography. Preventive measures to protect possible victims are presented as well as treatment strategies for offenders. Beside limiting access to the internet, these include therapy of comorbid psychiatric disorders and psychological problems (social isolation, bereavement, stress- and anger-management, guilt and shame, childhood traumata, cognitive distortion, victim empathy), psychopharmacotherapy and the enhancement of a more integrative and relationship-oriented sexuality.

    Aims and Background: Teeth form an excellent material for anthropological, genetic, odontologic and forensic investigations. The aim of this study was to establish the genetic control of sexual dimorphism in tooth size amongst siblings of Goan children in age range of 14-22 years. Materials and Methods: Twenty-two sibling pairs were selected (22 males and 22 females) to assess genetic control of sexual dimorphism in tooth size. Alginate impressions were obtained for maxillary and mandibular arches and study models were prepared. Measurements were done using Zoom Digimatic Vernier Calipers with a resolution of 0.01 mm. Statistical Analysis: Correlation between mesiodistal and buccolingual tooth sizes amongst siblings was calculated using Pearson’s correlation coefficient. Results: A statistically significant association was found between Mesiodistal Widths of Permanent Maxillary Right and Left Second Molars and between Maxillary Right and Left First Premolars amongst sibling pairs. A statistically significant association was also found between Buccolingual Widths of Mandibular Right and Left First Premolars amongst sibling pairs. This statistically significant correlation found amongst siblings establishes a genetic control over sexual dimorphism in these teeth. Conclusion: The genetic basis of sexual dimorphism in human dentition was ascertained as a significant correlation was found between mesio-distal and bucco-lingual widths of premolars between sibling pairs.

    The field of sexual trauma is one of the most controversial and value-laden in mental health. The three factors which most affect adult sexual desire and function are the type of sexual trauma, how the sexual incidents were dealt with at the time and, most important, whether the person views her/himself as a survivor or victim. The assessment and treatment program described focuses on couple sex therapy with a special focus on processing the sexual trauma, honoring the person's veto and being 'partners in healing'. The core therapeutic theme is valuing intimate, erotic sexuality, which reinforces being a proud survivor rather than a shameful, anxious or angry victim. It is crucial to create a relapse prevention program to ensure that the person with the sexual trauma history continues to experience the positive roles of adult couple sexuality. PMID:22005207

    Introduction There has been limited investigation of the sexuality and sexual dysfunction in non-heterosexual subjects by the sexual medicine community. Additional research in these populations is needed. Aims To investigate and compare sexuality and sexual function in students of varying sexual orientations. Methods An internet-based survey on sexuality was administered to medical students in North American between the months of February and July of 2008. Main Outcome Measures All subjects provided information on their ethnodemographic characteristics, sexual orientation, and sexual history. Subjects also completed a series of widely-utilized instruments for the assessment of human sexuality (International Index of Erectile Function [IIEF], Female Sexual Function Index [FSFI], Premature Ejaculation Diagnostic Tool [PEDT], Index of Sex Life [ISL]). Results There were 2,276 completed responses to the question on sexual orientation. 13.2% of male respondents and 4.7% of female respondents reported a homosexual orientation; 2.5% of male and 5.7% of female respondents reported a bisexual orientation. Many heterosexual males and females reported same-sex sexual experiences (4% and 10%, respectively). Opposite-sex experiences were very common in the male and female homosexual population (37% and 44%, respectively). The prevalence of premature ejaculation (PEDT > 8) was similar among heterosexual and homosexual men (16% and 17%, P = 0.7, respectively). Erectile dysfunction (IIEF-EF < 26) was more common in homosexual men relative to heterosexual men (24% vs. 12%, P = 0.02). High risk for female sexual dysfunction (FSFI < 26.55) was more common in heterosexual and bisexual women compared with lesbians (51%, 45%, and 29%, respectively, P = 0.005). Conclusion In this survey of highly educated young professionals, numerous similarities and some important differences in sexuality and sexual function were noted based on sexual orientation. It is unclear whether the dissimilarities represent differing relative prevalence of sexual problems or discrepancies in patterns of sex behavior and interpretation of the survey questions.

    2015-01-01

    Sexual problems are highly prevalent among patients with psychiatric disorders. They may be caused by the psychopathology of the psychiatric disorder but also by its pharmacotherapy. Both positive symptoms (e.g., psychosis, hallucinations) as well as negative symptoms (e.g., anhedonia) of schizophrenia may negatively interfere with interpersonal and sexual relationships. Atypical antipsychotics have fewer sexual side-effects than the classic antipsychotics. Mood disorders may affect libido, sexual arousal, orgasm, and erectile function. With the exception of bupropion, agomelatine, mirtazapine, vortioxetine, amineptine, and moclobemide, all antidepressants cause sexual side-effects. Selective serotonin reuptake inhibitors (SSRIs) may particularly delay ejaculation and female orgasm, but also can cause decreased libido and erectile difficulties. SSRI-induced sexual side-effects are dose-dependent and reversible. Very rarely, their sexual side-effects persist after SSRI discontinuation. This is often preceded by genital anesthesia. Some personality characteristics are a risk factor for sexual dysfunction. Also patients with eating disorders may suffer from sexual difficulties. So far, research into psychotropic-induced sexual side-effects suffers from substantial methodologic limitations. Patients tend not to talk with their clinician about their sexual life. Psychiatrists and other doctors need to take the initiative to talk about the patient's sexual life in order to become informed about potential medication-induced sexual difficulties. PMID:26003261

  10. Influence of unrestrained access to erotica on adolescents' and young adults' dispositions toward sexuality.

    2000-08-01

    Because consensually accepted programs of sexual education are lacking, erotica have come to serve as the primary agent of sexual socialization. The new media technology gives prepubertal children and postpubertal adolescents ready access to erotica in all their manifestations. However, next to nothing is known about the consequences of the steadily increasing amount of such exposure. A brief overview of what is known and what remains unknown about the effects of pornography on young adults is presented. Thereafter, the focus is on the development of sexual callousness across the pubertal threshold, and on how this callousness might be influenced by extensive exposure to erotica. The erotica under consideration are not so much those explicitly depicting coital behaviors as those that are less explicit and present a fuller social context of sexual engagements. A program of research is outlined that would help provide an understanding of erotica's effects on adolescents' sexual callousness, an understanding that is sorely needed for the construction of effective educational efforts aiming at the removal of callousness and coercion from sexual relations.

    The purpose of this study is to examine the role of gender, religiosity, sexual activity, and sexual knowledge in predicting attitudes toward controversial aspects of sexuality among Turkish university students. Participants were 162 female and 135 male undergraduate students who were recruited on a volunteer basis from an urban state university in Turkey. The SKAT-A Attitude Scale along with background information form, sexual activities inventory, and sexual knowledge scale were administered to the participants. Simultaneous multiple regression analyses revealed that religiosity, particularly attendance to religious services was the most significant predictor in explaining university students' attitudes toward masturbation, abortion, homosexuality, pornography, and sexual coercion.

    Background and aims Sexual addiction, also known as hypersexual disorder, is associated with serious psychosocial problems for many people. Methods This study used questionnaires to investigate the effects of gender, sexual orientation and attachment (avoidance and anxiety) on sexual compulsion among 100 heterosexual and homosexual men and women. Results A positive correlation was found between anxious attachment and sexual compulsivity (r = 0.46; p < 0.01) and a positive correlation between avoidant attachment and sexual compulsivity (r = 0.39; p ≤ 0.01) in all participants. Secondly, an analysis of covariance showed a gender by sexual orientation interaction effect [F(1, 103) = 6.39, p < 0.01] but no attachment effect on sexual compulsivity. A follow-up comparison showed that lesbian women had higher rates of sexual compulsivity than heterosexual women [t (2, 50) = 5.08, p < 0.001] whereas there was non-significant difference in sexual compulsivity between homosexual and heterosexual men [t (2, 50) = 1.30, p = N.S.]. Discussion The results provide preliminary evidence for an association between attachment and sexual compulsivity and the effects of gender and sexual orientation on sexual compulsivity.

    Most research on sexual content in the media has focused on visual images such as those in TV, film, advertisements, and magazines. However, researchers have largely overlooked sexual content in novels. The popularity of novels and the potential for such literature to educate teens on sexual behaviors merits a closer examination into the sexual messages contained in popular adolescent literature. This study content analyzes the top 40 novels targeting adolescents. Results show that adolescent novels are replete with sex-related information, especially in novels targeted to girls. These sexual behaviors range from passionate kissing and romantic ideation to sexual intercourse. Over one third of the instances focus on references to sex, suggestive innuendos, or sexual descriptions; and an additional one third of sexual behavior involved sexual affection in the form of passionate kissing, intimate touching, and playful sexual behavior. Across the 40 books, there were 56 instances of sexual intercourse, most of which involved unmarried couples (94%); and many were in non-committal relationships. Moreover, sexual material rarely dealt with issues of abstinence, safe sex practices, and the health risks associated with sex. PMID:21660836

    Exponentially fitted Runge-Kutta-Nystrom (EFRKN) methods for the numerical integration of second-order IVPs with oscillatory solutions are derived. These methods integrate exactly differential systems whose solutions can be expressed as linear combinations of the set of functions {exp(?t),exp(-?t)}, , or equivalently {sin(?t),cos(?t)} when ?=i?, . Explicit EFRKN methods with two and three stages and algebraic orders 3 and 4 are constructed. In addition, a 4(3) embedded pair of explicit EFRKN methods based on the FSAL technique is obtained, which permits to introduce an error and step length control with a small cost added. Some numerical experiments show the efficiency of our explicit EFRKN methods when they are compared with other exponential fitting type codes proposed in the scientific literature.

    Contemporary theory in cognitive neuroscience distinguishes, among the processes and utilities that serve categorization, explicit and implicit systems of category learning that learn, respectively, category rules by active hypothesis testing or adaptive behaviors by association and reinforcement. Little is known about the time course of categorization within these systems. Accordingly, the present experiments contrasted tasks that fostered explicit categorization (because they had a one-dimensional, rule-based solution) or implicit categorization (because they had a two-dimensional, information-integration solution). In Experiment 1, participants learned categories under unspeeded or speeded conditions. In Experiment 2, they applied previously trained category knowledge under unspeeded or speeded conditions. Speeded conditions selectively impaired implicit category learning and implicit mature categorization. These results illuminate the processing dynamics of explicit/implicit categorization.

    The governing equations for large-eddy simulation are derived from the application of a low-pass filter to the Navier-Stokes equations. It is often assumed that discrete operations performed on a particular grid act as an implicit filter, causing results to be sensitive to the mesh resolution. Alternatively, explicit filtering separates the filtering operation, and hence the resolved turbulence, from the underlying mesh distribution alleviating some of the grid sensitivities. We investigate the use of explicit filtering in large-eddy simulation in order to obtain numerical solutions that are grid independent. The convergence of simulations using a fixed filter width with varying mesh resolutions to a true large-eddy simulation solution is analyzed for a turbulent channel flow at Re?=180, 395, and 640. By using explicit filtering, turbulent statistics and energy spectra are shown to be independent of the mesh resolution used.

  1. Comparing European and U.S. approaches to adolescent sexual health.

    1998-12-01

    European countries have significantly lower incidences of teen pregnancy, births, abortions, and sexually transmitted infections (STIs). To determine why some countries have so much better success helping adolescents develop into sexually healthy adults, Advocates for Youth and the University of North Carolina developed a European study tour on adolescent sexual behavior and responsibility during summer 1998. The specific goal was to explore which factors contribute to better sexual health among adolescents in the Netherlands, Germany, and France. The differences between countries are exemplified in the recent age-specific birth data; for every 1000 girls aged 15-19 years, the birth rate is 64 in the US, 13 in Germany, 9 in France, and 7 in the Netherlands. Evidence was found during the trip that the promotion of sexual health and responsible choices can be as effective in the US as it is in Europe. Promoting contraceptives and making them available to teens are the norm in the countries studied, and such ready availability of contraceptives and explicit sexual education has not increased teens' levels of sexual activity. In fact, the median age at first intercourse is 16.4 years in the US, 17 in Germany, 17.4 in France, and 17.8 in the Netherlands. Politics have unfortunately polarized and frustrated sexuality education in the US. PMID:12322060

    This study examined the interactive effects of injunctive norm exposure and hostile and benevolent sexist attitudes on men's sexually aggressive responses during a behavioral analogue paradigm in which they interacted online with a bogus female partner. Heterosexual adult men (n = 201), recruited from an online sample, read fictional information regarding other men's approval of misogynistic, paternalistic, or egalitarian treatment of women, or non-gender-relevant control information. Through a media preference survey, men then learned that their female partner disliked sexual content in films, after which they had an opportunity to send her up to 120 sec' worth of either a sexually explicit or nonsexual film clip. Validating the online sexual aggression paradigm, men with a 1-year history of sexual assault exhibited more sexually aggressive responding during the film selection paradigm. Moreover, exposure to injunctive norm information produced a boomerang effect, such that men high in hostile sexist attitudes showed an increase in sexual aggression when confronted with paternalism and gender equality norms. Conversely, exposure to paternalism and gender equality norms suppressed the otherwise protective function of high benevolent sexism in reducing men's sexually aggressive tendencies. The implications of these results for social norms interventions are discussed. PMID:26174353

  3. A genuinely developmental theory of sexual enjoyment and its implications for psychoanalytic technique.

    PubMed

    Fonagy, Peter

    2008-03-01

    A small computer-assisted word frequency analysis, indicating the extent of explicit concern with sexuality in the psychoanalytic literature, has revealed an apparent decline of psychoanalytic interest in psychosexuality. The apparent decline may be related to the limitations of drive theory and object relations approaches in offering persuasive and comprehensive accounts of the psychosexual. A new model of human sexual experience is proposed, rooted in an integration of French psychoanalytic ideas with recent developmental observational research, that once again places sexuality at the center of psychoanalytic clinical inquiry. Because emotion regulation arises out of the mirroring of affect by a primary caregiver and sexual feelings are unique in that they are systematically ignored and left unmirrored by caregivers, sexual feelings remain fundamentally dysregulated in all of us. Adult sexual experience serves as a way of coming to organize the psychosexual. The model accounts for some aspects of the phenomenology of sexual arousal and suggests ways of understanding pathological distortions of sexual behavior. The nature of the psychosexual is explored in the analytic treatment of an adolescent boy. PMID:18430700

    INTRODUCTION.: Medical education in sexual health in the United States and Canada is lacking. Medical students and practicing physicians report being underprepared to adequately address their patients' sexual health needs. Recent studies have shown little instruction on sexual health in medical schools and little consensus around the type of material medical students should learn. To address and manage sexual health issues, medical students need improved education and training. AIM.: This meeting report aims to present findings from a summit on the current state of medical school education in sexual health and provides recommended strategies to better train physicians to address sexual health. METHODS.: To catalyze improvements in sexual health education in medical schools, the summit brought together key U.S. and Canadian medical school educators, sexual health educators, and other experts. Attendees reviewed and discussed relevant data and potential recommendations in plenary sessions and then developed key recommendations in smaller breakout groups. RESULTS.: Findings presented at the summit demonstrate that the United States and Canada have high rates of poor sexual health outcomes and that sexual health education in medical schools is variable and in some settings diminished. To address these issues, government, professional, and student organizations are working on efforts to promote sexual health. Several universities already have sexual health curricula in place. Evaluation mechanisms will be essential for developing and refining sexual health education. CONCLUSIONS.: To be effective, sexual health curricula need to be integrated longitudinally throughout medical training. Identifying faculty champions and supporting student efforts are strategies to increase sexual health education. Sexual health requires a multidisciplinary approach, and cross-sector interaction between various public and private entities can help facilitate change. Areas important to address include: core content and placement in the curriculum; interprofessional education and training for integrated care; evaluation mechanisms; faculty development and cooperative strategies. Initial recommendations were drafted for each. PMID:23551542

    Background: Sexuality is an important aspect of the personality of an individual and influences psychological, physical and social well-being of both men and women. It is a paradox, that in the country where ‘kamasutra’ (by Vatsyayana) took birth, there is a lack of research publications and sexuality related literature; hence the current study was conducted, to estimate the prevalence and association of sexual disorders with various socio-demographic variables, in the selected rural population. Materials and Methods: Subjects who were sexually active and fulfilled the study criteria were administered Arizona Sexual Experience Scale as screening tool for the presence of sexual problems. Those who were found to be having sexual problems were interviewed further using appropriate questionnaires. Results: 21.15% of the male subjects were diagnosed to have one (or more) sexual disorder. Prevalence of erectile dysfunction was found to be 15.77%, male hypoactive sexual desire disorder (HSDD) 2.56%; premature ejaculation was found to be prevalent in 8.76% of the male subjects. Around 14% of the female subjects were diagnosed to have female sexual disorders. Prevalence of female arousal dysfunction was found to be 6.65%, female HSDD 8.87%, female anorgasmia 5.67%, female dyspareunia 2.34% and female sexual aversion disorder was found to be prevalent in 0.37% of the female subjects. Conclusion: This study concluded that one in five males and one in seven females were suffering from one (or more) sexual disorder. Improving the training of undergraduate medical and nursing students in sexuality related issues, increasing trained individuals in sexual medicine by starting new courses, providing sex education to the general population using media and merging sexual health care with primary care, are likely to play a significant role in addressing the increasing sexual health morbidity.

    Heteronormative assumptions can negatively influence the lives of young gay and bisexual men, and recent sociological analyses have identified the negative impacts of heteronormativity on heterosexual men (e.g. 'fag discourse' targeted at heterosexual adolescents). However, insights into how heteronormative discourses may be (re)produced in clinical settings and how they contribute to health outcomes for gay, bisexual and heterosexual men are poorly understood. This analysis draws on in-depth interviews with 45 men (15-25 years old) and 25 clinicians in British Columbia, Canada, to examine how heteronormative discourses affect sexually transmitted infection testing. The sexually transmitted infection/HIV testing experience emerged as a unique situation, whereby men's (hetero)sexuality was explicitly 'interrogated'. Risk assessments discursively linked sexual identity to risk in ways that reinforced gay men as the risky 'other' and heterosexual men as the (hetero)normal and, therefore, relatively low-risk patient. This, in turn, alleviated concern for sexually transmitted infection/HIV exposure in heterosexual men by virtue of their sexual identity (rather than their sexual practices), which muted discussions around their sexual health. The clinicians also positioned sexual identities and practices as important 'clues' for determining their patients' social contexts and supports while concurrently informing particular tailored clinical communication strategies. These findings highlight how men's experiences with sexually transmitted infection/HIV testing can (re)produce heteronormative assumptions and expectations or create opportunities for more equitable gendered relations and discourses.

    Increasing emphasis is being placed on the identification and management of sexual abuse in children. Family physicians have a role to play in identifying and treating these children. Some common myths about sexual abuse are that assaults are made mostly by strangers, that sexual abuse is rare, and that there's nothing wrong with sex between adults and children. Indicators in the child may be physical or behavioral. In the family, indicators include fathers with low self-esteem, poor relationships with wives, tendency to be domineering and restrictive, and mothers who are passive. Immediate and longterm intervention includes legal, protective and treatment components. The essential factors in successful intervention are belief in the child's disclosure; communication of that belief to the child; and immediate protection of the child and siblings. PMID:21286177

    From the child conception to the early years of life, couples generally present less sexual activity. Parenthood constraints are a burden for the couple's relationships. Generally, persistent sexual difficulties six months after delivery, despite those generated by depression or altered health raise the question of an alteration in the quality of the couple's relationships and lack of satisfaction of the mother with her partner's involvement in family life. Numerous parameters can be implied, especially with persistent trouble of desire, such as fatigue, body image problems and libido lessening of the partner due to modifications of his status. Women who presented sexual difficulties before pregnancy remain the same. In all cases, appropriate information can avoid the intimacy's difficulties and contribute to maintain pleasure and intimacy even when vaginal penetration remains difficult. PMID:25262091

    Background/Significance High rates of HIV infection and other sexually transmitted infections (STIs) related to high risk sexual behaviors are a public health problem in the U.S. Hispanics have the second highest rates of HIV infection among racial/ethnic minorities. Previous research with Hispanic men has identified a number of factors that influence sexual risk and render Hispanic men at risk for HIV/STIs. These factors vary by sexual orientation. Despite these differences in sexual risk by sexual orientation, no study to date has compared the sexual behaviors of Hispanic men by sexual orientation. Objective The purpose of this study was to compare the sexual behaviors of a sample of Hispanic men by sexual orientation. Method A descriptive, cross-sectional design was used to collect data from 163 Hispanic men in South Florida, 80 heterosexual and 83 MSM. Participants completed measures of sexual health, sexual behaviors, and demographics. Results No statistically significant differences were found between the two groups of men in terms of age of sexual debut, number of sexual partners during the previous 3 months, condom usage during the previous 3 months, HIV testing history, and substance use during sex. Statistically significant differences were found between the two groups of men in terms of certain STIs. Implications Hispanic men as a population may engage in high risk sexual behaviors that place them at risk for HIV/STIs. More research is needed to develop both culturally tailored and sexual orientation appropriate interventions to assist Hispanic men reduce high risk sexual behaviors. PMID:25663832

  15. Beyond Sexual Orientation: Integrating Gender/Sex and Diverse Sexualities via Sexual Configurations Theory.

    2015-07-01

    Sexual orientation typically describes people's sexual attractions or desires based on their sex relative to that of a target. Despite its utility, it has been critiqued in part because it fails to account for non-biological gender-related factors, partnered sexualities unrelated to gender or sex, or potential divergences between love and lust. In this article, I propose Sexual Configurations Theory (SCT) as a testable, empirically grounded framework for understanding diverse partnered sexualities, separate from solitary sexualities. I focus on and provide models of two parameters of partnered sexuality--gender/sex and partner number. SCT also delineates individual gender/sex. I discuss a sexual diversity lens as a way to study the particularities and generalities of diverse sexualities without privileging either. I also discuss how sexual identities, orientations, and statuses that are typically seen as misaligned or aligned are more meaningfully conceptualized as branched or co-incident. I map out some existing identities using SCT and detail its applied implications for health and counseling work. I highlight its importance for sexuality in terms of measurement and social neuroendocrinology, and the ways it may be useful for self-knowledge and feminist and queer empowerment and alliance building. I also make a case that SCT changes existing understandings and conceptualizations of sexuality in constructive and generative ways informed by both biology and culture, and that it is a potential starting point for sexual diversity studies and research.

    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.

    An explicitly correlated version of the distinguishable-cluster approximation is presented and extensively benchmarked. It is shown that the usual F12-type explicitly correlated approaches are applicable to distinguishable-cluster theory with single and double excitations, and the results show a significant improvement compared to coupled-cluster theory with singles and doubles for closed and open-shell systems. The resulting method can be applied in a black-box manner to systems with single- and multireference character. Most noticeably, optimized geometries are of coupled-cluster singles and doubles with perturbative triples quality or even better. PMID:25681891

    The goal of this paper is to give an explicit construction of the Fock spaces of the parafermion and the paraboson algebra, for an infinite set of generators. This is equivalent to constructing certain unitary irreducible lowest weight representations of the (infinite rank) Lie algebra so({infinity}) and of the Lie superalgebra osp(1 vertical bar {infinity}). A complete solution to the problem is presented, in which the Fock spaces have basis vectors labeled by certain infinite but stable Gelfand-Zetlin patterns, and the transformation of the basis is given explicitly. Alternatively, the basis vectors can be expressed as semi-standard Young tableaux.

    A convective event over the Gulf of Mexico is used to address the question of how well nonhydrostratic convectively explicit models initialized by imposing a 'bubble', typically a temperature perturbation, on a horizontally homogeneous stratification background field, respond to usually subtle variations on meso-beta scale thermodynamic structure. Whether a meso-beta scale convective precipitation pattern can be produced numerically by performing a group of convectively explicit simulations is studied. Storm-scale low-level forcing is found to be important for producing desired convective precipitation patterns. The additional numerical approaches that must be incorporated to understand and forecast meso-beta scale weather events are considered.

    Code loops are certain Moufang loop extensions of doubly even binary codes which are useful in finite group theory (e.g. Conway's construction of the Monster). We give several methods for explicitly constructing code loops as centrally twisted products. More specifically, after establishing some preliminary examples, we show how to use decompositions of codes to build code loops out of more familiar pieces, such as abelian groups, extraspecial groups, or the octonion loop. In particular, we use Turyn's construction of the Golay code to give a simple explicit construction of the Parker loop, one which may have applications to the study of the Monster.

    2002-09-01

    The effect of including an explicit delay time (due to driver reaction) on the optimal velocity model is studied. For a platoon of vehicles to avoid collisions, many-vehicle simulations demonstrate that delay times must be well below the critical delay time determined by a linear analysis for the response of a single vehicle. Safe platoons require rather small delay times, substantially smaller than typical reaction times of drivers. The present results do not support the conclusion of Bando et al. [M. Bando, K. Hasebe, K. Nakanishi, and A. Nakayama, Phys. Rev. E 58, 5429 (1998)] that explicit delay plays no essential role. PMID:12366309

    This study examined the intergenerational transmission of implicit and explicit attitudes toward smoking, as well as the role of these attitudes in adolescents’ smoking initiation. There was evidence of intergenerational transmission of implicit attitudes. Mothers who had more positive implicit attitudes had children with more positive implicit attitudes. In turn, these positive implicit attitudes of adolescents predicted their smoking initiation 18-months later. Moreover, these effects were obtained above and beyond the effects of explicit attitudes. These findings provide the first evidence that the intergenerational transmission of implicit cognition may play a role in the intergenerational transmission of an addictive behavior. PMID:20126293

    2010-09-01

    Phase-coherent communications typically requires a reliable phase-tracking algorithm. An initial phase estimate with training symbols allows a receiver to compensate for a motion-induced Doppler shift. Following the training period, however, explicit phase tracking can be avoided in time reversal communications that has been implemented on a block-by-block basis to accommodate time-varying channels. This is accomplished by a smaller block size and adaptive channel estimation using previously detected symbols on a symbol-by-symbol basis. The proposed time reversal approach without explicit phase tracking is demonstrated using experimental data (12-20 kHz) in shallow water. PMID:20815434

  4. Sexual selection in fungi.

    Nieuwenhuis, B P S; Aanen, D K

    2012-12-01

    The significance of sexual selection, the component of natural selection associated with variation in mating success, is well established for the evolution of animals and plants, but not for the evolution of fungi. Even though fungi do not have separate sexes, most filamentous fungi mate in a hermaphroditic fashion, with distinct sex roles, that is, investment in large gametes (female role) and fertilization by other small gametes (male role). Fungi compete to fertilize, analogous to 'male-male' competition, whereas they can be selective when being fertilized, analogous to female choice. Mating types, which determine genetic compatibility among fungal gametes, are important for sexual selection in two respects. First, genes at the mating-type loci regulate different aspects of mating and thus can be subject to sexual selection. Second, for sexual selection, not only the two sexes (or sex roles) but also the mating types can form the classes, the members of which compete for access to members of the other class. This is significant if mating-type gene products are costly, thus signalling genetic quality according to Zahavi's handicap principle. We propose that sexual selection explains various fungal characteristics such as the observed high redundancy of pheromones at the B mating-type locus of Agaricomycotina, the occurrence of multiple types of spores in Ascomycotina or the strong pheromone signalling in yeasts. Furthermore, we argue that fungi are good model systems to experimentally study fundamental aspects of sexual selection, due to their fast generation times and high diversity of life cycles and mating systems.

    Disorders of sexual development (DSDs) are a group of disorders in which there is discordance between anatomic or hormonal sex and sex chromosome complement. These disorders present with ambiguity in the newborn period and require prompt evaluation to determine the underlying cause for treatment and appropriate sex assignment of the infant. Neonatologists should confer with a multidisciplinary team for the diagnostic evaluation and management of patients with DSDs. This article provides a review of normal sexual development, algorithms used for evaluating infants with ambiguous genitalia, and conditions that can present with ambiguous genitalia in the newborn period.

    The objective causes of sexual impotency include chronic prostatitis arising from bacterial infection (1/3 of patients have sexual disturbances), congestive prostatitis (owing to sexual hyperstimulation treated with temporary blockage of testosterone), and hemorrhoids. Diabetes, advances tuberculosis, neurological and psychological diseases also negatively impact sexual potency as does alcoholism. The increase of dopamine and the decrease of serotonin stimulate, while the reverse of these reduce sexual activity. Endocrine medicines, drugs that affect the central nervous system, antihypertension drugs, anticoagulants, vincristine, cimetidine, and clofibrate generally lower the libido. Methods to be avoided because of a negative effect on sexual life include coitus interruptus. The intolerance of sensitivity to the sperm of the partner also complicates the sexual life of a couple. Sexual disorders without apparent cause include the lack of harmony, attention, and education about sexual matters. Other disorders can be caused by rape (only 25% of rapists are caught and punished), as 50% of female victims have psychological sequelae with a sexual tone; venereophobia; repulsive cutaneous symptoms; emotional taste; fear of inability to complete the sexual act; timidity or excessive shyness with anxiety about intimacy; and lack of emotional attraction to the partner. Eventually, the lack of a satisfactory sexual life has an effect on the integrity of conjugal life, as it is frequently the cause of divorce. PMID:1823415

    In this article, the authors consider how trans men's decisions about physical body modifications impact their sense of themselves as gendered and sexual actors. Based on interviews with 74 trans men, the authors explore how their embodiment, gender identity, erotic ideation, lifetime of sexual practices, and domain of potential partners-what the authors term "sexual habitus"-can be affirmed, transformed, or challenged as their embodiment changes. These changes underscore the dynamic relationship between gender and sexuality and illustrate how bodies matter in sexual trajectories across the life course. PMID:24392744

    2009-06-01

    This study aimed to investigate how people manage their sexuality when practicing naturism in the United Kingdom (UK). Thirty-nine self-identified naturists from across the UK were interviewed. Sexuality, when practicing naturism, was found often to be suppressed through the use of rules, geographical isolation and thoughts and behaviour. Some participants found ways of exploring and enjoying their sexuality by keeping feelings hidden and/or seeking out more sympathetic naturist environments. Naturist environments may offer a unique space in which to explore aspects of our sexuality that are currently pathologised, criminalised or commercialised. This has important implications for sexual health policy and promotion. PMID:18926761

  20. An explicit finite element formulation for dynamic strain localization and damage evolution in metals

    SciTech Connect

    Mourad, Hashem M; Bronkhorst, Curt A; Addessio, Francis L

    2010-12-16

    An explicit finite element formulation, used to study the behavior and failure mechanisms of metallic materials under high strain rate loading, is presented. The formulation is based on the assumed-strain approach of Fish and Belytschko [1988], which allows localization bands to be embedded within an element, thereby alleviating mesh sensitivity and reducing the required computational effort. The behavior of the material outside localization bands (and of the virgin material prior to the onset of strain localization) is represented using a Gurson-type coupled plasticity-damage model based on the work of Johnson and Addessio [1988]. Assuming adiabatic conditions, the response of the localization band material is represented by a set of constitutive equations for large elasticviscoplastic deformations in metals at high strain rates and high homologous temperatures (see Brown et al. [1989]). Computational results are compared to experimental data for different metallic alloys to illustrate the advantages of the proposed modeling strategy.

  1. Implementation of the nonlocal microplane concrete model within an explicit dynamic finite element program

    SciTech Connect

    Cofer, W.F.

    1992-03-01

    The microplane concrete material model is based upon assumptions regarding the behavior of the material components. At any point, the response to the strain tensor on arbitrarily oriented surfaces is considered. Simple, softening stress-strain relationships are assumed in directions perpendicular and parallel to the surfaces. The macroscopic material behavior is then composed of the sum of the effects. The implementation of this model into the explicit, nonlinear, dynamic finite element program, DYNA3D, is described. To avoid the spurious mesh sensitivity that accompanies material failure, a weighted integral strain averaging approach is used to ensure that softening is nonlocal. This method is shown to be effective for limiting the failure zone in a concrete rod subjected to an impulse loading. 36 refs., 7 figs.

    In sexual population, recombination reshuffles genetic variation and produces novel combinations of existing alleles, while selection amplifies the fittest genotypes in the population. If recombination is more rapid than selection, populations consist of a diverse mixture of many genotypes, as is observed in many populations. In the opposite regime, which is realized for example in the facultatively sexual populations that outcross in only a fraction of reproductive cycles, selection can amplify individual genotypes into large clones. Such clones emerge when the fitness advantage of some of the genotypes is large enough that they grow to a significant fraction of the population despite being broken down by recombination. The occurrence of this ‘clonal condensation’ depends, in addition to the outcrossing rate, on the heritability of fitness. Clonal condensation leads to a strong genetic heterogeneity of the population which is not adequately described by traditional population genetics measures, such as linkage disequilibrium. Here we point out the similarity between clonal condensation and the freezing transition in the random energy model of spin glasses. Guided by this analogy we explicitly calculate the probability, Y, that two individuals are genetically identical as a function of the key parameters of the model. While Y is the analog of the spin-glass order parameter, it is also closely related to rate of coalescence in population genetics: two individuals that are part of the same clone have a recent common ancestor.

    Abstract Background: Lichen sclerosus (LS) is a chronic inflammatory condition that is known to arise on the vulva. Many women with LS report vulvar pain, often affecting a patient's quality of life. In this study, the sexual function of LS patients, with and without pain, was compared to control populations. Materials and Methods: A case-control study to examine the relationship between LS and sexual dysfunction was conducted. A total of 335 women presenting to the gynecology clinic were included in the study: 197 women with biopsy confirmed LS were compared to two control groups (95 asymptomatic women were “healthy” controls and 43 women had vulvovaginal candidiasis) on self-reported current health complaints, medical and surgical history and current symptoms such as pain and itching, type and frequency of sexual activity, and satisfaction with sexual activity. Results: Women with LS reported less frequent sexual activity than healthy controls (p=0.007) and Candida controls (p=0.04). Currently sexually active women with LS were significantly less likely to report vaginal intercourse (71.6%) than healthy controls (89.0%, p=0.003) or Candida controls (100%, p=0.0003), even though similar proportions of all three groups reported that vaginal intercourse was important. Satisfaction towards the quality of current sexual activity was significantly lower among women with LS compared with both the healthy and Candida control groups. 23.7% of women with LS reported that sexual activity was rarely or never satisfactory as compared with 0% of healthy controls (p<0.0001) and 6.5% of Candida controls (p=0.03). Conclusion: Women with LS have less frequent sexual activity and less satisfying sexual activity when compared with controls. PMID:25162790

    Background: Infertility makes an essential challenge to the sexual life of couples, especially infertile women. When pregnancy does not happen, infertile women think that sexual intercourse is not fruitful and sexual desire became reduce gradually. Infertile women progressively forget that their sexual relationship is also a response to their natural need. Objective: This qualitative study was conducted to explore the infertility consequences in the sexual behavior of infertile women. Materials and Methods: This was a qualitative content analysis study; and it was part of a widespread study, used a sequential mixed-method and conducted from August 2014 until February 2015. A purposeful sampling was used to recruit infertile women who had referred to Yazd Research and Clinical Center for Infertility. Data gathering techniques employed in this research included in-depth semi structured open face-to-face interviews and field notes. Credibility, transferability, confirm ability, and dependability were assessed for the rigor of the data collection. Results: Totally, 15 infertile women and 8 key informants were interviewed. Data analysis showed four themes about impact of infertility on female sexual behavior: 1/ Impact of infertility drugs on couple sexual behavior, 2/ Impact of assisted reproductive technologies on female sexual behavior, 3/ Timed intercourse during infertility and 4/ The psychological impact of infertility on sexual behavior. Conclusion: Some of Iranian infertile women could cope with their problems, but some of them were very affected by infertility drugs and assisted reproductive technologies procedures. Psychosexual counseling before medical treatment could help them to have a better sexual life. PMID:26644793

  5. Sexuality, rights and personhood: tensions in a transnational world

    PubMed Central

    2011-01-01

    Background This article discusses what happens when normative ‘global’ discourses of rights and individuated sexual identity confront the messiness of ‘local’ realities. It considers the tensions that emerge when the relationship between sexual and social identities is not obvious and the implications of such tensions for public health and sexual rights activism. These questions are addressed through debates over the naming of male-to-male sexualities and desires in the context of globalization and the growth of a large NGO (non-governmental organization) sector in urban Bangladesh. Methods The material in the paper draws on a research project undertaken in 2008-9 in Dhaka, Bangladesh. A fundamental objective was to produce a contextualized understanding of sexuality in Dhaka city. Methods used included structured interviews, focus group discussions and informal conversations with a range of participants (students, factory workers, public health professionals and sexual minorities). The aim was to generate a conceptual and analytical framework around sexuality and rights rather than to undertake an empirical survey of any one population. Results As descriptors, globalized identity categories such as Men who have Sex with Men (MSM), used by public health providers, the state and donors; and gay/lesbian, invoked by human rights activists and transnational NGOs, are too narrow to capture the fluid and highly context-specific ways in which gender and sexually nonconforming persons understand themselves in Bangladesh. Further, class position mediates to a significant degree the reception, appropriation or rejection of transnational categories such as MSM and Lesbian, Gay, Bisexual, Transgender (LGBT). The tension is reflected in the sometimes fraught relations between service providers to MSM, the people they serve and an emerging group who identify as LGBT. Conclusion A simple politics of recognition will be inadequate to the task of promoting health and human rights for all; such a strategy would effectively exclude individuals who do not necessarily connect their sexual practices with a specific sexual or social identity.

    Little research has been conducted to examine the influence of exposure to televised sexual content on adolescent sexuality or how parental intervention may reduce negative effects of viewing such content. This study uses self-report data from 1,012 adolescents to investigate the relations among exposure to sexually suggestive programming, parental mediation strategies, and three types of adolescent sexuality outcomes: participation in oral sex and sexual intercourse, future intentions to engage in these behaviors, and sex expectancies. As predicted, exposure to sexual content was associated with an increased likelihood of engaging in sexual behaviors, increased intentions to do so in the future, and more positive sex expectancies. Often, parental mediation strategies were a significant factor in moderating these potential media influences. PMID:21546986

  7. The relationship between sexual selection and sexual conflict.

    PubMed

    Kokko, Hanna; Jennions, Michael D

    2014-09-01

    Evolutionary conflicts of interest arise whenever genetically different individuals interact and their routes to fitness maximization differ. Sexual selection favors traits that increase an individual's competitiveness to acquire mates and fertilizations. Sexual conflict occurs if an individual of sex A's relative fitness would increase if it had a "tool" that could alter what an individual of sex B does (including the parental genes transferred), at a cost to B's fitness. This definition clarifies several issues: Conflict is very common and, although it extends outside traits under sexual selection, sexual selection is a ready source of sexual conflict. Sexual conflict and sexual selection should not be presented as alternative explanations for trait evolution. Conflict is closely linked to the concept of a lag load, which is context-dependent and sex-specific. This makes it possible to ask if one sex can "win." We expect higher population fitness if females win. PMID:25038050

    We examined verbal sexual health communication, pleasure discussions, and physical sexual communication in relation to condom use by young adult, heterosexual Latinos (ages 18-30 years). Participants (N = 220, 51% female) were recruited in a Midwestern state. Verbal sexual health communication was positively associated with consistent condom use among men (odds ratio [OR] = 2.66, p < .05) and women (OR = 3.12, p < .05). For men, pleasure discussions were negatively associated with consistent condom use (OR = 0.21, p < .05). For women, verbal sexual health communication was positively associated with condom use at last sex (OR = 2.75, p < .05), whereas physical sexual communication was negatively associated with condom use at last sex (OR = .29, p < .05). Various aspects of sexual communication may be important in HIV-prevention programs with young Latinos. Physical sexual communication and pleasure discussions, in particular, warrant further exploration given negative relationships with condom use. PMID:25305027
