    2018-05-01

    Single-sex schooling has been controversial for decades. The current study investigated the differences in friendships, dating, and past, present, and ideal sexual orientation, between 207 college students who attended single-sex secondary schools and 249 college students who attended coeducational secondary schools in Hong Kong, controlling for personal characteristics such as socioeconomic status. We found that, compared to graduates of coeducational schools, graduates of single-sex schools reported a different gender composition in intimate friendships favoring the same sex, less romantic involvement with other-sex close friends, older age at first date, fewer boyfriends or girlfriends, and more past same-sex sexuality. In contrast, we found no significant differences in the interactions with same-sex versus other-sex friends, most aspects of past or present dating engagement, or self-reported present or ideal sexual orientation. These findings give insight into the interpersonal outcomes of single-sex schooling and fill a gap in previous research which has focused on academic achievement and gender role stereotypes.

  7. Single-sex middle school science classrooms: Separate and equal?

    Science.gov (United States)

    Glasser, Howard M.

    The U.S. Department of Education's amended regulations to Title IX have attempted to expand the circumstances in which single-sex classes are permissible in public schools. This ethnographic study uses grounded theory to investigate aspects of one single-sex offering at a public, coeducational middle school. Applying elements of postmodern, queer, and sociocultural lenses, it examines the perspectives for this offering, shedding insight into the cultures of two single-sex classrooms and what it meant to be a boy or girl in this setting. Additionally, it focuses attention on the all-boy and all-girl science classes that were taught by the same teacher and examines what it meant to learn science as boys and girls in this program. Although participants supplied financial, socio-emotional, and academic reasons for these classes, the initial motivation for these classes stemmed from the teachers' desire to curb the amount of sex talk and related behaviors that were exhibited in their classrooms. Through these conversations and classroom events, the girls were constructed as idealized students, academically and behaviorally, who needed to be protected from boys' behaviors---both boys' dominating classroom behaviors and aggressive (hetero)sexual behaviors. Conversely, boys were constructed as needing help both academically and behaviorally, but in the specific discipline of science boys were identified as the sex that was more interested in the content and gained greater exposure to skills that could assist them in future science courses and careers. Overall, boys and girls, and the culture of their two classrooms, were regularly defined relative to each other and efforts were made to maintain these constructed differences. As a result, the classes and students were hierarchically ranked in ways that often pitted one sex of students, or the entire class, as better or worse than the other. The theory emerging from this study is that single-sex policies arise and survive

  8. Causal effects of single-sex schools on college entrance exams and college attendance: random assignment in Seoul high schools.

    Park, Hyunjoon; Behrman, Jere R; Choi, Jaesung

    2013-04-01

    Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul-the random assignment of students into single-sex versus coeducational high schools-to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. The three-level hierarchical model shows that attending all-boys schools or all-girls schools, rather than coeducational schools, is significantly associated with higher average scores on Korean and English test scores. Applying the school district fixed-effects models, we find that single-sex schools produce a higher percentage of graduates who attended four-year colleges and a lower percentage of graduates who attended two-year junior colleges than do coeducational schools. The positive effects of single-sex schools remain substantial, even after we take into account various school-level variables, such as teacher quality, the student-teacher ratio, the proportion of students receiving lunch support, and whether the schools are public or private.

    Gee, Kevin A; Cho, Rosa Minhyo

    2014-12-01

    Bullying is a growing public health concern for South Korean adolescents. In our quantitative investigation, we analyze the frequency with which Korean adolescents in single-sex versus coeducational schools are targets of or engage in three peer aggressive behaviors (verbal, relational (social exclusion), and physical (including theft)). We use two nationally representative datasets, the 2011 Trends in International Mathematics and Science Study (TIMSS) and the 2005 Korea Education Longitudinal Study (KELS), and rely on propensity score matching (PSM). For adolescent girls, we find that being in all-girls schools mitigates both their exposure to and engagement in peer victimization. For adolescent boys, we find that boys in all-boys schools have significantly higher odds of experiencing more frequent verbal and physical attacks versus their counterparts in coeducational schools. Our findings strongly suggest that interventions to mitigate peer victimization and aggression in Korea should consider the gendered schooling contexts in which they are implemented.

    Prendergast, Mark; O'Donoghue, John

    2014-11-01

    This research investigates the influence that gender, single-sex and co-educational schooling can have on students' mathematics education in second-level Irish classrooms. Although gender differences in mathematics education have been the subject of research for many years, recent results from PISA (Programme for International Student Assessment) show that there are still marked differences between the achievement and attitude of male and female students in Irish mathematics classrooms. This paper examines the influence of gender in more detail and also investigates the impact of single-sex or co-educational schooling. This is a follow on study which further analyses data collected by the authors when they designed a pedagogical framework and used this to develop, implement and evaluate a teaching intervention in four second-level Irish schools. The aim of this pedagogical framework was to promote student interest in the topic of algebra through effective teaching of the domain. This paper further analyses the quantitative data collected and investigates whether there were differences in students' enjoyment and achievement scores based on their gender and whether they attended single-sex or co-educational schools.

    2000-11-01

    There is proof that the educational system has conveyed unrealistic role expectations and has neglected to address the changing needs of girls. Children form attitudes about themselves and others based on the communications they get over time from parents, other adults, peers, and a variety of societal influences, including school. This study focused on two groups of tenth-grade high school, female, biology students in the Archdiocese of Philadelphia. The purpose was to compare attitude in science and academic achievement of females in a single-sex vs. a coeducational school. Data collection included three attitudinal surveys: Women in Science, Science Attitude Scale, and Perceptions of Science and Scientists, also the National Association of Biology Teachers/National Science Teachers High School Biology Examination Version B. administered as a pretest and posttest to measure academic achievement. These instruments were used to determine if the differences between attitudes and perceptions toward science and achievement in science were alike for females in a single-sex school and a coeducational school. The study also tested to see if females in a single-sex school would attain greater academic achievement in biology than girls in a coeducational school. The Chi-square statistic was used to analyze data in the three attitudinal surveys. The NABT/NSTA High School Biology Examination determined the students' initial and final competency levels in general biology. The mean science achievement of each of the two groups was tested for statistical significance using the t-test. In the two schools the t-test statistic showed significant difference between the pretest and a slight statistical difference on the posttest; the preferred analysis was an ANCOVA used to compare the posttest scores using the pretest as a covariate. The data implies that attitudes and perceptions are basically the same in both environments with minor differences. Results of these analyses suggest

  1. The effects of single-sex compared with coeducational schooling on students' performance and attitudes: a meta-analysis.

    Science.gov (United States)

    Pahlke, Erin; Hyde, Janet Shibley; Allison, Carlie M

    2014-07-01

    Proponents of single-sex (SS) education believe that separating boys and girls, by classrooms or schools, increases students' achievement and academic interest. In this article, we use meta-analysis to analyze studies that have tested the effects on students of SS compared with coeducational (CE) schooling. We meta-analyzed data from 184 studies, representing the testing of 1.6 million students in Grades K-12 from 21 nations, for multiple outcomes (e.g., mathematics performance, mathematics attitudes, science performance, educational aspirations, self-concept, gender stereotyping). To address concerns about the quality of research designs, we categorized studies as uncontrolled (no controls for selection effects, no random assignment) or controlled (random assignment or controls for selection effects). Based on mixed-effects analyses, uncontrolled studies showed some modest advantages for single-sex schooling, for both girls and boys, for outcomes such as mathematics performance but not for science performance. Controlled studies, however, showed only trivial differences between students in SS versus CE, for mathematics performance (g = 0.10 for girls, 0.06 for boys) and science performance (g = 0.06 for girls, 0.04 for boys), and in some cases showed small differences favoring CE schooling (e.g., for girls' educational aspirations, g = -0.26). Separate analyses of U.S. studies yielded similar findings (e.g., for mathematics performance g = 0.14 for girls and 0.14 for boys). Results from the highest quality studies, then, do not support the view that SS schooling provides benefits compared with CE schooling. Claims that SS schooling is particularly effective for U.S. ethnic minority boys could not be tested due to the lack of controlled studies on this question.

  8. The Single Sex Debate for Girls in Science: a Comparison Between Two Informal Science Programs on Middle School Students' STEM Identity Formation

    Science.gov (United States)

    Hughes, Roxanne M.; Nzekwe, Brandon; Molyneaux, Kristen J.

    2013-01-01

    Currently, there are policy debates regarding the efficacy and legality of single sex formal and informal education programs. This issue is particularly poignant in science education due to the historical marginalization of women in these fields. This marginalization has resulted in women being positioned as a stigmatized group within many science, technology, engineering, and mathematics (STEM) related fields. Research points to adolescence as the age where this sense of marginalization begins to develop. As a result, policy responses have utilized various frameworks such as: increased access for women, changing pedagogy to address women's learning styles, changing the language and culture of science to prevent marginalization of stigmatized groups, and finally exploring the role that individual identity plays in the marginalization of women. This study adds to the policy debate as it applies to single sex education by comparing middle school participants' STEM identity formation during two informal science learning environments (an all girls' STEM camp and a co-educational STEM camp). Additionally, this study focuses on the influence of camp activities within two informal science education programs: particularly the provision of role models and authentic STEM research activities, as means to improve STEM identity and make these fields relevant to the lives of middle school students. The results indicate that both camps improved girls' STEM identities. These findings suggest that the single sex environment is not as important to STEM identity as the pedagogy used within the program.

    2014-03-01

    This study examined the longitudinal effects of participation in an all-girls STEM summer camp on young women's interest in STEM fields and motivation to pursue these fields. The SciGirls camp has been in existence since 2006, with its goal of providing a safe space for young women to explore STEM careers and strengthen their interest in these careers. Over 166 middle school age girls have participated in the program since it began in 2006. Of those participants, 60 responded to at least one of the follow up surveys that are sent every three years - 2009 and 2012. The surveys attempt to determine participants' level of interest in STEM. The survey was qualitative in nature and asked open ended questions. Results indicated that the camp had a positive effect on participants' perceptions of scientists and their work. This study adds to the literature that looks at the longitudinal impacts of informal STEM educational programs that expose young women to female scientist role models and mentors. This study supports the research that claims that exposing young women at an early age to science role models can positively alter their perception of science careers which can eventually increase the number of women who pursue these careers. This increase is important at a time when men still outnumber women in many science and engineering fields. This study was funded in part by the National Science Foundation Division of Materials Research through DMR 0654118.

  19. Teachers' implementation of gender-inclusive instructional strategies in single-sex and mixed-sex science classrooms

    Science.gov (United States)

    Parker, Lesley H.; Rennie, Léonie J.

    2002-09-01

    Debate continues over the benefits, or otherwise, of single-sex classes in science and mathematics, particularly for the performance of girls. Previous research and analyses of the circumstances surrounding the implementation of single-sex classes warn that the success of the strategy requires due consideration of the nature of the instructional environment for both boys and girls, together with appropriate support for the teachers involved. This article reports the circumstances under which teachers were able to implement gender-inclusive strategies in single-sex science classes in coeducational high schools and documents some of the difficulties faced. The study was part of the Single-Sex Education Pilot Project (SSEPP) in ten high schools in rural and urban Western Australia. Qualitative and quantitative data were gathered during the project from teachers, students and classroom observations. Overall, it was apparent that single-sex grouping created environments in which teachers could implement gender-inclusive science instructional strategies more readily and effectively than in mixed-sex settings. Teachers were able to address some of the apparent shortcomings of the students' previous education (specifically, the poor written and oral communication of boys and the limited experience of girls with 'hands-on' activities and open-ended problem solving). Further, in same-sex classrooms, sexual harassment which inhibited girls' learning was eliminated. The extent to which teachers were successful in implementing gender-inclusive instructional strategies, however, depended upon their prior commitment to the SSEPP as a whole, and upon the support or obstacles encountered from a variety of sources, including parents, the community, students, and non-SSEPP teachers.

Development of novel sperm sexing technologies, or evaluation of the quality of existing methods, often requires a single-sperm, sex-typing method that is reliable and easy to perform. In the present study, we report the development, validation, and application of a simple, reliable, and cost-effective method for single-sperm sex typing using nested polymerase chain reaction (PCR), based on the amelogenin gene. Several hundred single sperm were isolated using a simple manual technique, or a high-speed flow-sorter, and were successfully sex-typed using the amelogenin nested PCR. Based on the pooled results of individual sperm, there was no significant difference in the semen sex ratio of unsorted (44.6% X-sperm and 55.4% Y-sperm) or X/Y-sorted semen (91.4% X-sperm and 94.0% Y-sperm), as compared to the expected ratio in unsorted semen or the post-sorting reanalysis data, respectively. The amelogenin single-sperm sexing method was an adaptable, accurate, and reliable tool for single-sperm sex typing.

    The process of starting a new program in computer science and engineering, heavily based on applied mathematics and only open to women, is described in this paper. The program was introduced into an educational system without any tradition in single-sex education. Important observations made during the process included the considerable interest in mathematics and curiosity about computer science found among female students at the secondary school level, and the acceptance of the single-sex program by the staff, administration, and management of the university as well as among male and female students. The process described highlights the importance of preparing the environment for a totally new type of educational program.

    Sex education is described as education about human sexual anatomy, sexual reproduction, sexual intercourse, reproductive health, emotional relations, reproductive rights and responsibilities, abstinence, contraception, family planning, body image, sexual orientation, sexual pleasure, values, decision making, communication, dating, relationships, sexually transmitted infections (STIs) and how to avoid them, and birth control methods. This study was conducted to explore perception of parents about school sex education and assess the attitude of teachers and students towards school sex education. A cross-sectional quantitative and qualitative study was conducted on randomly selected 386 students, total census of 94 teachers and 10 parents in Merawi Town from March 13-27, 2011. Data were collected using self-administered structured questionnaire and in-depth interview guideline. Multiple linear regression analysis was performed using total score to determine the effect of the independent variables on the outcome variable and thematic analysis was used to analyze the qualitative data. All study participants have favourable attitude towards the importance of school sex education. They also agreed that the content of school sex education should include abstinence-only and abstinence-plus based on mental maturity of the students. That means at early age (Primary school) the content of school sex education should be abstinence-only and at later age (secondary school) the content of school sex education should be added abstinence-plus. The students and the teachers said that the minimum and maximum introduction time for school sex education is 5 year and 25 year with mean of 10.97(SD±4.3) and 12.36(SD±3.7) respectively. Teacher teaching experiences and field of studies have supportive idea about the starting of school sex education. Watching romantic movies, reading romantic materials and listening romantic radio programs appear to have a contribution on the predictor of

  5. ``Sex Hormones'' in Secondary School Biology Textbooks

    Nehm, Ross H.; Young, Rebecca

    2008-11-01

    This study explores the extent to which the term “sex hormone” is used in science textbooks, and whether the use of the term “sex hormone” is associated with pre-empirical concepts of sex dualism, in particular the misconceptions that these so-called “sex hormones” are sex specific and restricted to sex-related physiological functioning. We found that: (1) all the texts employed the term “sex hormone”; (2) in all texts estrogen is characterized as restricted to females and testosterone is characterized as restricted to males; and (3) in all texts testosterone and estrogen are discussed as exclusively involved in sex-related physiological roles. We conclude that (1) contemporary science textbooks preserve sex-dualistic models of steroid hormones (one sex, one “sex hormone”) that were rejected by medical science in the early 20th century and (2) use of the term “sex hormone” is associated with misconceptions regarding the presence and functions of steroid hormones in male and female bodies.

    To assess the knowledge and attitude to sex education among secondary school teachers in Enugu. A cross sectional study of 300 teachers drawn from nine randomly selected secondary schools in Enugu metropolis was carried out. Pre-tested self administered structured questionnaire was used as instrument for data collection. Three hundred teachers, 215 females and 85 males were interviewed. The mean age of the teachers was 38.1+/-7.5 years. Sixty-nine (23.0%) had adequate knowledge of sex education and 282 (94.0%) approved the inclusion of sex education into the school curriculum. The commonest reason for disapproval of sex education was fear that it would lead to promiscuity amongst the students. Educational status and marital status of the teachers were significant determinants of positive attitude to sex education psex education according to the teachers is 11-15 years. Two hundred and thirty eight (79.3%) respondents were of the opinion that teachers needed to be trained to provide sex education to students and 244 (81.3%) admitted that sex education was not in the school curriculum. Secondary school teachers are in support of provision of sex education to students. However they need training and skills on how to present sex information in a positive manner to achieve the desired goal. There is need to include sex education in the school curriculum.

    To assess sixth graders' knowledge and curiosity about sex-related topics that can guide the development of sexual health education and healthcare delivery. Sixth graders (n = 795) in eight ethnically diverse schools participating in an evaluation of a sex education curriculum submitted 859 anonymous questions that were content analyzed. The χ(2) analysis examined whether the themes varied by coed/single-sex environments or by school-level sexual risk. Sexual activity, female anatomy, reproduction, and puberty were the most frequently mentioned topics, whereas, questions on STIs, sexual violence, and drug/alcohol use were fewer. Questions that avoided sexual topics came from lower sexual-risk schools; students at higher-risk schools asked about sexual initiation, contraception, vaginal and anal sex, general health, and pain during sex. Single-sex classrooms elicited more direct and explicit questions about sex. The results are relevant to educators and healthcare providers who ask and answer questions from early adolescents regarding sexual health.

    To investigate sex education in Swedish schools regarding content, satisfaction, and suggested improvements, as described by teenagers and young adults. Waiting-room survey conducted among 225 female patients (aged 13-25) at youth and student health clinics in one large-, and one medium-sized Swedish city. Most participants (97%, n = 218) had received sex education in school, of varying content and quality. Sixty percent thought basic body development was sufficiently covered. Insufficiently covered topics included sexual assault (96%), sexual harassment (94%), pornography (90%), abortion (81%), emergency contraception (80%), fertility (80%), and pregnancy (59%). Thirty percent received no information about chlamydia, and almost half reported that condyloma and human papillomavirus had not been addressed. The youngest respondents (13-19 years) were significantly more likely to have been told about emergency contraception, homosexuality, bisexuality, and transsexuality. Nearly half (46%) considered 'acceptable' the knowledge gained from sex education provided at school whereas more than a third considered it 'poor' or 'very poor'. Suggested improvements included more information, more discussion, greater emphasis on sexual diversity, and more knowledgeable teachers. Content and quality of sex education varied greatly. Most respondents thought many topics were insufficiently covered, sex education should be more extensive, and teachers better educated.

    This study explored the sexual subjectivities of older Australian women. In this article we present findings from 15 qualitative interviews with Australian women aged 55-81 who were single at the time of interview. The majority of these women were single following divorce or separation, with a smaller number of women who were widowed or never in a long-term relationship. We found that these women's sexual desire and sexual activity were fluid and diverse across their life course. Although some participants desired a romantic or sexual relationship, they were also protective of their independence and reluctant to re-enter into a relationship in later life. Our findings indicate that these women's sexual subjectivities were shaped by dominant norms of ageing, sex, and gender. At the same time, older women are challenging and resisting these norms, and beginning to renegotiate sexuality in later life. Copyright © 2015 Elsevier Inc. All rights reserved.

    2005-12-01

    The development of single-sex medium secure units for women has been driven by concern about the vulnerability of women to sexual abuse and exploitation in mixed-sex secure settings. Less is known about how women patients and staff perceive gender segregation and their experiences in single-sex units. To examine the impact of gender segregation on the safety of women patients detained in medium secure psychiatric facilities. A qualitative study was conducted involving individual interviews with 58 male and female staff and 31 women patients in single-sex and mixed-sex medium secure units throughout England and Wales. Women patients in both types of units reported high levels of actual and threatened physical and sexual violence. Women in single-sex units reported intimidation, threats and abuse by other women patients, although they were less vulnerable to sexual abuse and exploitation and serious physical assault. Further development of single-sex secure units for women may not be justified on the grounds of safety issues alone. Risk assessment of forensic psychiatric patients must include a full assessment of their safety within the psychiatric setting.

    1985-12-01

    The sexist division of labour, particularly in the occupational sector, which is believed to be more eminent in developing countries than in the developed ones, is reinforced by school textbooks. This state of affairs is hampering sex-role equality on the way to emancipation. Various Syrian school textbooks have been scrutinized and proved to be malebiased in content and language. Despite quantitative growth of education, the emancipatory quality of the school textbooks leaves much to be desired. The government has had the chance since 1963 to produce textbooks conductive to its promise of sex-role equality in education. The textbooks portray males for a bustling world of decision making, while conditioning the females to seek fulfilment in the background where servitude and support are the only requirement. Females are derogated and victimized. These contents, which are internalized at school and reproduced in society, certainly do not serve development. The exclusion of one-half of the population from contributing to the tasks of development is a waste of human talent which no society can afford. Furthermore, the sexist portrayal of females in Syrian textbooks is a pale reflection of Arab women in Arab history and literature.

    We report on a longitudinal study designed to assess possible sex differences in math achievement, math ability, and math-related tasks during the primary school age years. Participants included over 200 children from one public school district. Annual assessments included measures of math ability, math calculation achievement scores, rapid naming and decoding tasks, visual perception tests, visual motor tasks, and reading skills. During select years of the study we also administered tests of counting and math facts skills. We examined whether girls or boys were overrepresented among the bottom or top performers on any of these tasks, relative to their peers, and whether growth rates or predictors of math-related skills differed for boys and girls. Our findings support the notion that sex differences in math are minimal or nonexistent on standardized psychometric tests routinely given in assessments of primary school age children. There was no persistent finding suggesting a male or female advantage in math performance overall, during any single year of the study, or in any one area of math or spatial skills. Growth rates for all skills, and early correlates of later math performance, were comparable for boys and girls. The findings fail to support either persistent or emerging sex differences on non-specialized math ability measures during the primary school age years. PMID:20463851

    Sport specialization and movement asymmetry have been separately discussed as potential risk factors for lower extremity injury. Early specialization may lead to the development of movement asymmetries that can predispose an athlete to injury, but this has not been thoroughly examined. Athletes rated as specialized would exhibit greater between-limb anterior reach asymmetry and decreased anterior reach distance on the Y-balance test (YBT) as compared with nonspecialized high school athletes, and these differences would not be dependent on sex. Cross-sectional study. Level 3. Two hundred ninety-five athletes (117 male, 178 female; mean age, 15.6 ± 1.2 years) from 2 local high schools participating in basketball, soccer, volleyball, and tennis responded to a questionnaire regarding sport specialization status and performed trials of the YBT during preseason testing. Specialization was categorized according to 3 previously utilized specialization classification methods (single/multisport, 3-point scale, and 6-point scale), and interactions between specialization and sex with Y-balance performance were calculated using 2-way analyses of variance. Single-sport male athletes displayed greater anterior reach asymmetry than other interaction groups. A consistent main effect was observed for sex, with men displaying greater anterior asymmetry and decreased anterior reach distance than women. However, the interaction effects of specialization and sex on anterior Y-balance performance varied based on the classification method used. Single-sport male athletes displayed greater anterior reach asymmetry on the YBT than multisport and female athletes. Specialization classification method is important because the 6- and 3-point scales may not accurately identify balance abnormalities. Male athletes performed worse than female athletes on both of the Y-balance tasks. Clinicians should be aware that single-sport male athletes may display deficits in dynamic balance, potentially

    Limited evidence exists on salary differences between male and female academic physicians, largely owing to difficulty obtaining data on salary and factors influencing salary. Existing studies have been limited by reliance on survey-based approaches to measuring sex differences in earnings, lack of contemporary data, small sample sizes, or limited geographic representation. To analyze sex differences in earnings among US academic physicians. Freedom of Information laws mandate release of salary information of public university employees in several states. In 12 states with salary information published online, salary data were extracted on 10 241 academic physicians at 24 public medical schools. These data were linked to a unique physician database with detailed information on sex, age, years of experience, faculty rank, specialty, scientific authorship, National Institutes of Health funding, clinical trial participation, and Medicare reimbursements (proxy for clinical revenue). Sex differences in salary were estimated after adjusting for these factors. Physician sex. Annual salary. Among 10 241 physicians, female physicians (n = 3549) had lower mean (SD) unadjusted salaries than male physicians ($206 641 [$88 238] vs $257 957 [$137 202]; absolute difference, $51 315 [95% CI, $46 330-$56 301]). Sex differences persisted after multivariable adjustment ($227 783 [95% CI, $224 117-$231 448] vs $247 661 [95% CI, $245 065-$250 258] with an absolute difference of $19 878 [95% CI, $15 261-$24 495]). Sex differences in salary varied across specialties, institutions, and faculty ranks. For example, adjusted salaries of female full professors ($250 971 [95% CI, $242 307-$259 635]) were comparable to those of male associate professors ($247 212 [95% CI, $241 850-$252 575]). Among specialties, adjusted salaries were highest in orthopedic surgery ($358 093 [95% CI, $344 354-$371 831]), surgical subspecialties ($318 760 [95

    2010-01-01

    This study seeks to explore what young women want from their school-based sex education. Qualitative methods were used to explore the perspectives of two groups of young women from Uganda and Scotland. Of particular importance to all the young women were: a diverse sex education curriculum appropriate to the ages of the students, being taught by an outside female facilitator, single-sex classes and access to a female teacher. Furthermore, they proposed that discussion between small groups of friends is very useful. The Scottish group said that having a young teacher, teaching about emotions and relationships and being guided through their own decision making is also important. The Ugandan group emphasized the importance of being taught by female family members and having written materials provided on sex education. The study showed that young women from different backgrounds have strong opinions about sex education, and are an important resource for policy makers.

    We examine the effect of single-sex classes on the pass rates, grades, and course choices of students in a coeducational university. We randomly assign students to all-female, all-male, and coed classes and, therefore, get around the selection issues present in other studies on single-sex education. We find that one hour a week of single-sex education benefits females: females are 7.5% more likely to pass their first year courses and score 10% higher in their required second year classes than...

    Ovotesticular disorder of sex development (OT DSD) is a rare disorder of sex development characterized by the presence in the same individual of both histologically proven testis and ovary. There are scant data from the Indian subcontinent regarding this disorder. The aim of this study was to describe the clinical, biochemical, imaging, cytogenetic, surgical, and histopathologic findings and outcomes of patients with OT DSD from Western India. The records of patients referred to our center for disorders of sex development between 2005 and 2013 were reviewed, and 7 patients were found to have histologically proven OT DSD. The median age at presentation was 8 years (range, 2 months to 25 years). Clinical presentation varied from genital ambiguity and inguinal swelling at birth to gynecomastia and cyclical hematuria after puberty. Karyotype was 46, XX in 6 patients and 46, XY in 1 patient. All patients underwent pelvic ultrasonography, laparoscopy, and surgery for removal of gonads not congruous with the chosen sex of rearing. Gender assignment for all the patients was done by the parents at birth, which was mainly influenced by the external genitalia and sociocultural influences, with 5 out of the 7 patients being reared as males. There was no evidence of gonadal tumors in our study. OT DSD should be considered as one of the differential diagnoses in cases of ambiguous genitalia with nonpalpable or asymmetrical gonads, pubertal gynecomastia, and cyclical hematuria, irrespective of the karyotype or internal genitalia.

    Full Text Available A large portion of the population consists of adolescents aged by 12 to 19 years. During this period of human life occur several behavioral factors involving sexuality that intrigues many researchers, teachers and parents and according to the Parâmetros Curriculares Nacionais (PCNs, sex education must be taught in schools as a crosscutting theme. The aim of this study was to investigate perceptions and attitudes towards sexual education among elementary school Indigenous teachers in a rural school in Dourados-MS. Data collection was conducted through a questionnaire completed by individual teachers. The results show that teachers consider important to work with sex education in elementary schools involving different areas of knowledge and with the help of health professionals. Most teachers work or have worked this theme in his classes, and consider the students receptive and interested, however, some teachers have difficulty in approaching the subject. One of the difficulties encountered are related to the low acceptance of their parents, highlighting the need for guidance on the same theme. The Parâmetros Curriculares Nacionais ensures that the sex education should begin in early school years.

  1. The Concept of a Single-sex Optional Discussion Session in Introductory Astronomy at a Publicly Funded University

    Science.gov (United States)

    Shawl, S.

    1996-12-01

    The concept of single-sex education for science and mathematics has recently received renewed discussion in both the popular and professional literature. So important is the topic within higher education that the Duke Journal of Gender Law and Policy sponsored a symposium called "Gender & The Higher Education Classroom: Maximizing the Learning Environment" in February 1996 (http://www.duke.edu/ jrd4/djgcnf96.htm). The concept is especially controversial in publicly supported educational institutions. The idea of offering an optional discussion session limited to a single sex in a university-level introductory astronomy course at a State-supported school was considered through discussions with a number of faculty and administrators, and through a questionnaire aimed at determining student attitudes toward the concept. The results of the student questionnaire will be presented. (While the questionnaire results will be seen to be in favor of such an optional discussion session, such sessions have not been offered.)

The teachers answered a semi-structured questionnaire that aimed at verifying the pedagogical practice in sex education, difficulties related to the theme, and the need for training. Most teachers were male (69% and aged between 25 and 35 years (74%. Half held a graduate degree (54% in human sciences (49%. Nearly all teachers find difficulties in working the topic (89% and need training (93%. Contents on sexuality were not addressed in the Political Pedagogical Projects (76% and the biology program aimed at teaching the theme (55%, a reality that disagrees with the National Curricular Standards, which is based on transversality. Partnerships between health and education must be established, particularly between the Family Health Strategy the higher education institutions, providing public school teachers with the necessary didactic-pedagogical support to address sexuality in the classroom.

    2008-06-01

    Establishing or preserving single-sex schooling has been widely discussed as a way of bringing more girls into the natural sciences. We test the assumption that the beneficial effects of single-sex education on girls' self-concept of ability in masculine subjects such as physics are due to the lower accessibility of gender-related self-knowledge in single-sex classes. N=401 eighth-graders (mean age 14.0 years) from coeducational comprehensive schools. Random assignment of students to single-sex vs. coeducational physics classes throughout the eighth grade. At the end of the year, students' physics-related self-concept of ability was measured using a questionnaire. In a subsample of N=134 students, the accessibility of gender-related self-knowledge during physics classes was assessed by measuring latencies and endorsement of sex-typed trait adjectives. Girls from single-sex physics classes reported a better physics-related self-concept of ability than girls from coeducational classes, while boys' self-concept of ability did not vary according to class composition. For both boys and girls, gender-related self-knowledge was less accessible in single-sex classes than in mixed-sex classes. To the extent that girls' feminine self-knowledge was relatively less accessible than their masculine self-knowledge, their physics-related self-concept of ability improved at the end of the school year. By revealing the importance of the differential accessibility of gender-related self-knowledge in single- and mixed-sex settings, our study clarifies why single-sex schooling helps adolescents to gain a better self-concept of ability in school subjects that are considered inappropriate for their own sex.

  4. Correlation of Sex Education and the Racial Composition of a School District

    Schaa, Kelly

    The purpose of the project was to determine whether there was a correlation between the racial makeup of a school district and the decision to provide sex education in its schools. Interviews were conducted with six different school districts across Santa Clara County, California. After the interviews, it was determined that the racial diversity did not play a role in deciding if sex education would be taught. This researcher did learn that a lack of educational funding had an effect on the school districts and their decisions. Due to this lack of funding for schools, educational programs, such as sex education, were not being provided to the students.

  11. Single Locus Maintains Large Variation of Sex Reversal in Half-Smooth Tongue Sole (Cynoglossus semilaevis).

    Sex determination is a fundamental biological process for individual sex development and population sex ratios. However, for some species, the primary sex might be altered during development, and individuals can develop into the opposite sex. Sex reversal may happen in insects, reptiles, amphibians, and fishes. In half-smooth tongue sole ( Cynoglossus semilaevis ), some genetically female fish irreversibly reverse to pseudomales, resulting in higher costs in aquaculture owing to a lower growth rate of male fish during a 2-yr growth period. Here, we identified a locus with large controlling effect on sex reversal in the half-smooth tongue sole through genome-wide association study with high-density single nucleotide polymorphisms (SNPs). This SNP is located at the third intron of the F-box and leucine rich repeat protein 17 ( FBXL17 ) gene on the Z chromosome, and it has two alleles, A and T. Genetic females with Z A W genotypes will never reverse into phenotypic males, but those with Z T W genotypes can sometimes undergo sex reversal. This SNP explains 82.7% of the genetic variation, or 58.4% of the phenotypic variation. Based on our results, a reproductive management program could be developed to improve the phenotypic female ratio in aquaculture, and elucidate the mechanism of sex reversal in half-smooth tongue sole. We expect that these findings will have a substantial impact on the population management in many harvested species where sex reversal occurs. Copyright © 2017 Jiang and Li.

    2010-01-01

    This study assesses how variations in heteronormative culture in high schools affect the well-being of same-sex-attracted youth. The authors focus on the stigmatization of same-sex attraction (rather than identity or behavior) to better understand how heteronormativity may marginalize a wide range of youth. Specifically, the authors use data from the National Longitudinal Study of Adolescent Health to examine how variation across schools in football participation, religious attendance, and urban locale affects same-sex-attracted adolescents' depressive symptoms, self-esteem, fighting, and academic failure. The results suggest that though same-sex-attracted youth are at greater risk for decreased well-being, these youth are at higher risk in nonurban schools and in schools where football and religion have a larger presence. Results vary for boys and girls: The urban locale of a school has a larger impact for boys, while school religiosity has a greater impact for girls. PMID:27917022

    Reproductive capability is now established at earlier age. But the subject of adolescent sexuality is taboo in most societies. There is widespread ignorance about risks of unprotected sex, problems among adolescents. Unfortunately need of sex education is not perceived and fulfilled in India especially in rural areas. The present study was conducted to assess the need and demonstrate the impact of sex education among adolescent school children. The impact of sex education workshop was tested by analysing pre- and postintervention questionnaire. The felt need of sex education increased considerably and the knowledge regarding contraceptives increased from manifolds after the intervention. There was significant increase in knowledge about menstrual hygiene, sexually transmitted diseases, etc, after sex education workshop. This study concludes that there is intense need of sex education and it has significant impact on knowledge of adolescent school children.

    Eighteen adolescents were videotaped during same-sex and opposite-sex interactions in the eleventh and twelfth grades. In both grades, females felt more comfortable during same-sex interactions than during opposite-sex interactions, and they rated their same-sex partners more positively than did males. Females in both grades and males in eleventh grade showed more peer intimacy than did males in twelfth grade. Eleventh-grade females showed the most playful behaviors (the most engaged state). More synchrony (matching of behavior) was found for the animated state in the twelfth grade as compared with the eleventh grade.

    Other-sex friendship (girls with boy friends, boys with girl friends) has been associated with substance use, but how the gender composition of schools influences substance use has not been known. We analyzed the influence of other-sex friendship on substance use and took into account the proportion of each gender group at the schools, and hypothesized that other-sex friendship is associated with higher levels of substance use and that schools with a majority of males have higher levels of use than female-majority schools. In 2013, a social network survey was carried out in six European cities. In each city, schools were selected and 11,015 adolescents (aged 14-16) were recruited (participation rate = 79.4%). We collected data on smoking, binge drinking, cannabis use, and peer group composition. Other-sex friendship was associated with smoking, binge drinking, and cannabis use for girls and with smoking for boys. Substance use was more frequent in schools with a majority of males. Conclusions/Importance: Adolescent girls are best protected from substance use if they are in gender-balanced schools, but in same-sex friendship. This offers new perspectives on gender mixing at school. In schools with a majority of boys, more attention should be paid to girls, and gender-specific health promotion programs should be implemented. This European study is the first to take into account both individual (other-sex friendship) and contextual (gender composition of schools) gender interactions. It confirms previous studies on other-sex friendship, while shedding light on the influence of gender-normative contexts on substance use.

    Many school-based abstinence-only sex education curricula state that sexual activity outside of marriage is likely to have harmful psychological effects. Recent advances in neuroscience have expanded our understanding of the neural underpinnings of romantic love, marriage, sexual desire, and sexual behavior and improved our understanding of adolescent brain development. In this article, we review recent advances in neuroscience and clarify what is known about the link between neural development and adolescent romantic and sexual behavior and what opportunities exist for future research. Whereas the evidence from neuroscience does not yet allow for clear conclusions about the cost or benefits of early romantic relationships and sexual behavior, it does indicate that providing developmentally appropriate education contributes to lifelong sexual health. Developing policies and practices for school-based sex education that reflect current research will best support the sexual and reproductive health of adolescents throughout their lives. © 2015, American School Health Association.

    To date, there is limited published data on same-sex male couples and single men using assisted reproduction treatment to build their families. The objective of this retrospective study was to better understand treatment considerations and outcomes for this population when using assisted reproduction treatment. A total of 37 same-sex male couples and eight single men (seven homosexual and one heterosexual) who attended the CReATe Fertility Centre for assisted reproduction services were studied. There was a 21-fold increase in the number of same-sex male couples and single men undergoing assisted reproduction treatment since 2003. The mean age was 46years (24-58). Twenty-eight couples (76%) chose to use spermatozoa from both partners to fertilize their donated oocytes. Most men (32 same-sex male couples and seven single men; 87%) obtained oocytes from an anonymous donor, whereas five couples and one single man (13%) had a known donor. Anonymous donors who were open to be contacted by the child after the age of 18 were selected by 67% of patients. Of all 25 deliveries, eight (32%) were sets of twins. All of the twins were half genetic siblings. Copyright © 2013 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    2014-10-01

    Little research has explored parental engagement in schools in the context of adoptive parent families or same-sex parent families. The current cross-sectional study explored predictors of parents' self-reported school involvement, relationships with teachers, and school satisfaction, in a sample of 103 female same-sex, male same-sex, and heterosexual adoptive parent couples (196 parents) of kindergarten-age children. Parents who reported more contact by teachers about positive or neutral topics (e.g., their child's good grades) reported more involvement and greater satisfaction with schools, regardless of family type. Parents who reported more contact by teachers about negative topics (e.g., their child's behavior problems) reported better relationships with teachers but lower school satisfaction, regardless of family type. Regarding the broader school context, across all family types, parents who felt more accepted by other parents reported more involvement and better parent-teacher relationships; socializing with other parents was related to greater involvement. Regarding the adoption-specific variables, parents who perceived their children's schools as more culturally sensitive were more involved and satisfied with the school, regardless of family type. Perceived cultural sensitivity mattered more for heterosexual adoptive parents' relationships with their teachers than it did for same-sex adoptive parents. Finally, heterosexual adoptive parents who perceived high levels of adoption stigma in their children's schools were less involved than those who perceived low levels of stigma, whereas same-sex adoptive parents who perceived high levels of stigma were more involved than those who perceived low levels of stigma. Our findings have implications for school professionals, such as school psychologists, who work with diverse families. Copyright © 2014 Society for the Study of School Psychology.

  10. Parents' views on sex education in schools: How much do Democrats and Republicans agree?

    Directory of Open Access Journals (Sweden)

    Leslie Kantor

    Full Text Available More than 93 percent of parents place high importance on sex education in both middle and high school. Sex education in middle and high school is widely supported by parents regardless of their political affiliation. Using data from a large diverse sample of 1,633 parents of children aged 9 to 21 years, we examined whether views on sex education differed by parents' political affiliation. More than 89 percent of parents that identified as Republicans or Democrats support including a wide range of topics in sex education including puberty, healthy relationships, abstinence, sexually transmitted diseases (STDs and birth control in high school. In middle school, 78 percent or more of both parents that identified as Republicans and Democrats support the inclusion of those topics. Controlling for key demographic factors, parents that identified as Democrats are more likely than those that identified as Republicans to support the inclusion of the topics of healthy relationships, birth control, STDs, and sexual orientation in both middle and high school. However, a strong majority of Republican parents want all these topics included in sex education. Sex education which includes a broad set of topics represents an area of strong agreement between parents of both political parties.

    Conclusion: Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls.

  1. A Test in the High School Context of Berdahl's Status Theory of Sex-Based Harassment.

    Science.gov (United States)

    Shute, Rosalyn H

    2017-10-01

    This study, carried out in the high school context, is the first direct test of Berdahl's status theory of sex-based harassment. The theory covers not just male harassment of females, but female harassment of males and same-sex harassment. Participants were 771 males and 679 females, from Years 8 to 10, in five co-educational lower socioeconomic status (SES) Australian city schools, participating in a wider study of peer victimization. They indicated on a 5-point scale (from never to almost every day) how frequently they had experienced each of six sex-based harassment behaviors over the previous year, from same-sex and from opposite-sex peers, and responded to a question about sense of safety at school. Nonparametric analyses supported five of seven hypotheses derived from the theory: boys harassed others most often, girls were harassed most often, boy-to-girl harassment was the most frequent, girls harassed girls more than they did boys, and girl-to-boy harassment was the least frequent. However, contrary to the theory, boys' same-sex harassment was no more frequent than that between girls, and girl-to-girl harassment was just as threatening to victims' sense of safety as boy-to-boy harassment. The study largely supports Berdahl's theory. The unexpected results can be understood in terms of the intimate nature of adolescent girls' groups in high schools and their centrality for identity formation. In this context, girls are highly motivated to defend their status in terms of stereotypically feminine standards regarding appearance, sexual activity, and access to high-status boys. The theory implies that structural changes to reduce the salience of sex differences and sex stereotyping will be crucial to efforts to address sex-based harassment.

    Early sexual activity can undermine adolescents' future school success and health outcomes. The purpose of this study was to assess the role of a family homework component of a comprehensive sex education intervention in delaying sexual initiation for early adolescents and to explore what social and contextual factors prevent adolescents from completing these family homework activities. This mixed methods study included 6th- and 7th-grade survey responses from 706 students at 11 middle school schools receiving a sex education intervention, as well as interviews from a subset of 33, 7th-grade students from the larger sample. Adolescents who completed more family homework assignments were less likely to have vaginal intercourse in 7th grade than those who completed fewer assignments, after controlling for self-reports of having had vaginal intercourse in 6th grade and demographic variables. Participants' explanations for not completing assignments included personal, curriculum, and family-based reasons. Family homework activities designed to increase family communication about sexual issues can delay sex among early adolescents and contribute to school-based sex education programs. Successful sex education programs must identify and address barriers to family homework completion. © 2013, American School Health Association.

    Full Text Available This is the micro research which studied the connection between gender and violence between older primary school students with the goal of discovering exposure of gender members to violence in school context and the ways of reaction to the violence. The researchers from different scientific disciplines have been permanently involved in studying the problem of violence for more than a decade with the goal to lessen the high percentage of violence in schools. In this sense, this research, with its range and character, represents the contribution in discovering characteristics of violence in schools in one specific local area, which could fill in the wholeness of this phenomenon. The research involved students of the final grade of primary school on the territory of the municipality of Svilajnac (which is in central part of Serbia and it was performed in December 2015. 236 students were surveyed. The survey consisted of the following questions a which questioned the social matrix of families in which the students live b which questioned presence and frequency of different types of violence between students in primary schools c which questioned the attitudes of students of both genders about the violence, exposure to violence in school and the ways of reacting to violence. In the frame of quantitative analysis of the data the following was applied: percentual research of frequencies and Pierson's hi-square test (x2 for testing of hyphothesis about the significance of differences. The main results of the research showed: a There is no statistically significant difference in exposure to violence in school between male and female students of primary school age; both genders are exposed to verbal and physical violence and male students (45.7% are more exposed to physical, and female students (38.3% are more exposed to verbal violence. bThere is no statistically significant difference in the readiness of students considering their gender to help another

    2007-11-01

    Schools create environments in which some sexual feelings, behaviors, and relationships are stigmatized, and this may have negative consequences for adolescents with nonheterosexual romantic attractions. This stigma can lead them to withdraw and disengage from school at a critical time of preparation for adulthood, which can compromise opportunities for future success. Previous research has demonstrated that sexual minority youth report greater levels of school-related problems, including a weaker sense of attachment to school and more trouble with teachers and peers. This lack of social integration is likely to affect their educational success. Data from the National Longitudinal Study of Adolescent Health and the newly collected Adolescent Health and Academic Achievement study provide the first opportunity to fully explore whether and to what extent same-sex attracted youth enter adulthood with an educational disadvantage. In this study, we examine (1) whether same-sex attracted adolescents have lower levels of academic success, (2) if their lower academic success is explained by a lack of social integration at school, and (3) whether these relationships differ for boys and girls. Results suggest that same-sex attracted students, particularly boys, do suffer academically, and that this is in part a result of school-related problems and risk factors such as emotional distress and substance use; however, a great deal of the disadvantage fails to be explained by these factors. Additionally, while same-sex attracted boys show poorer academic performance, same-sex attracted girls do not, suggesting that gender may shape how sexual minority youth experience and respond to marginalizing school environments.

    The authors used state-of-the-art concept mapping approaches to examine structural institutional effects of church and secular high schools on the types of sexual and HIV-prevention education messages transmitted to learners in Zimbabwe. Participants were school teachers (n = 26), school counselors (n = 28), and pastors involved in student pastoral care (n = 14; males = 27, females = 41). They reported on messages perceived to influence sexual decisions of learners in their school setting. The self-report data were clustered into message types using concept mapping and contrasted for consistency of content and structure both between and within type of school. The authors also engaged in curriculum document study with member checks in the participant schools to determine convergence of the evidence on school-type effects of the messages transmitted to students. Church schools prioritized faith-informed sexual and HIV-prevention messages, whereas both types of schools prioritized Life skills education and a future focus. Secular schools prioritized sex and HIV messages in the context of community norms. Facts about HIV and AIDS were relatively underemphasized by church schools. The implicit knowledge values that differentiate types of schools influence learner access to information important for their sexual decisions.

  4. Both COMT Val158Met single nucleotide polymorphism and sex-dependent differences influence response inhibition

    Directory of Open Access Journals (Sweden)

    Valentina eMione

    2015-05-01

    Full Text Available Reactive and proactive control of actions are cognitive abilities that allow to deal with a continuously changing environment by adjusting already programmed actions. They also set forthcoming acts by evaluating the outcome of the previous ones. Earlier studies highlighted sex related differences in the strategies and in the pattern of brain activation during cognitive tasks involving reactive and proactive control. To further identify sex-dependent characteristics in the cognitive control of actions, in this study we have assessed whether/how differences in reactive and proactive control were modulated by the COMT Val158Met single nucleotide polymorphism, a genetic factor known to influence the functionality of the dopaminergic system, in particular at the level of prefrontal cortex. Two groups of male and female participants were further sorted according to their genotype (Val/Met, Val/Val and Met/Met and tested in a stop signal task, a consolidated tool to measure reactive and proactive control in experimental and clinical settings. In each group of participants we estimated both a measure of the capacity to react to unexpected events and the ability of monitoring their performance. The between groups comparison of these measures indicated a poorer ability of male individuals carrying the Val/Val genotype in error-monitoring, suggesting that differences between sexes could be influenced by the efficiency of COMT and that other sex-specific factors have to be considered. The comprehension of inter-groups behavioral and physiological correlates of cognitive control will provide more accurate diagnostic tools for predicting the incidence and the development of pathologies like ADHD or deviant behaviors as drug or alcohol abuse.

  5. California parents' preferences and beliefs regarding school-based sex education policy.

    Constantine, Norman A; Jerman, Petra; Huang, Alice X

    2007-09-01

    Policy debates over the merits of abstinence-only versus comprehensive approaches to sex education are ongoing, despite well-documented public support for comprehensive sex education. Although parents are key stakeholders in the outcomes of these debates, their views have been less thoroughly considered. A random digit dial survey of 1,284 California parents was conducted in 2006. Parents were asked about their sex education policy preferences, the importance of teaching selected topics at different grade levels and reasons for their preferences. Cross-tabulations and odds ratios were used to assess regional and other subgroup differences. Overall, 89% of parents reported a preference for comprehensive sex education, and 11% for abstinence-only education. Support for comprehensive sex education was high in all regions (87-93%) and across all subgroup characteristics: race or ethnicity (79-92%), age (86-94%), education (84-93%), household income (87-92%), religious affiliation (86-91%), religious service attendance (69-96%) and ideological leaning (71-96%). Four types of reasons for preferences emerged: those focused on the consequences of actions, on the importance of providing complete information, on the inevitability of adolescents' engaging in sex and on religious or purity-based morality concerns. While 64% of abstinence-only supporters cited the last type (absolutist reasons), 94% of comprehensive sex education supporters cited one of the first three (pragmatic reasons). The high levels of support for comprehensive sex education across California's diverse regions and demographic subgroups suggest that such support may be generalizable to communities and school districts both in California and around the country. Furthermore, ideological differences might be less important to the sex education debates than the distinction between pragmatic and absolutist perspectives.

    Increasing antisocial and violent behaviors in adolescents and young adults present serious challenges for public health. Children with persistent high levels of aggressiveness are often associated with developing conduct disorders later in life. Early detection of highly aggressive children and sociodemographic risk-modifying factors are important for developing effective preventive strategies. The present study was undertaken to assess levels of aggressiveness for detecting highly aggressive children in sample populations of primary school children in an urban setting and determine significant biosociocultural risk-modifying factors in this scenario. The study was conducted during August-September, 2015 in 5 primary schools of South Delhi Municipal Corporation. Sociodemographic data on 2080 students were collected. Overall aggressiveness scores (OA-Scores) were estimated using a self-report questionnaire in Hindi. Categorizing students according to their OA-Scores, the data revealed that highly aggressive children constituted 4.3% of the study population. Analysis showed significant influence of (a) gender: boys displayed higher levels of aggressiveness compared to girls; (b) dietary pattern: omnivores showed higher aggressiveness than vegetarians; and (c) school environment: boys in mixed-sex (coeducational) schools displayed lower aggressiveness than from single-sex schools. Statistically significant influences of religion (Hindu/Muslim) and family type (joint/nuclear) on aggressiveness profiles were not noticeable. Vegetarian diets and mixed-sex education act as protective factors in the development of aggressiveness in children, especially among boys. Extending investigations to populations differing in geography and cultural backgrounds are warranted to verify present results.

    The aim of this study was to compare the effect of presorting centrifugation (cushioned [CC] or single-layer colloid [SLC]), with simple dilution (SD), on the quality of sex-sorted stallion semen before and after sorting and after freezing and thawing. Four ejaculates from each of two fertile stallions were collected 1 week apart and evaluated for percent total sperm motility (TM), percent viable acrosome-intact sperm (VAI), and DNA quality (percentage of DNA fragmentation index). Freezing caused, independently from CC and SLC treatments, a significant decrease of TM (P < 0.05) and VAI (P < 0.05) in both unsorted and sorted semen. On the other hand, sorting did not impair TM and VAI and, interestingly, improved DNA quality in all treatments only before freezing (28 vs 13, 28 vs 10, 22 vs 7 in SD, CC, and SLC for unsorted vs sorted groups, respectively; P < 0.05); this positive effect was lost in the same samples after freezing and thawing, suggesting that the freezing process reduces the DNA quality of sex-sorted sperm. Our results suggest that CC and SLC are not able to select those spermatozoa that possess a better ability to withstand sperm processing associated with sperm sorting and freezing.

    Hunt, Gary L.

    The purpose of this study was to investigate the relationships between the gender composition of a laboratory group and student behaviors, self-efficacy, and quiz performance, within the college physics laboratory. A student population was chosen and subdivided into two groups, which were assigned either same-sex or coed laboratory teams while executing identical laboratory activities and instruction. Assessments were carried out prior to instruction, during the course, and at the end of one semester worth of instruction and laboratory activities. Students were assessed in three areas: behaviors exhibited during laboratory activities, self-efficacy, and scores on laboratory quizzes. Analyses considered the differences in outcomes after a single semester of physics laboratories that differed only in team gender organization. The results indicated that there were no statistically significant differences in behavior variable, self-efficacy or laboratory quiz scores between same sex teams and coed teams. There were also no statistically significant differences between genders, and no interaction effect present. In a post-hoc analysis of the individual behaviors data, it was noted that there is present a practical difference in the individual behaviors exhibited by males and females. This difference implies a difference in how males and females successfully engage in the laboratory activities.

    The literature has documented theoretical/conceptual models delineating the facilitating role of peer relationships in academic and non-academic outcomes. However, the mechanisms through which peer relationships link to those outcomes is an area requiring further research. The study examined the role of adolescents' perceptions of their relationships with same-sex and opposite-sex peers in predicting their academic performance and general self-esteem and the potentially mediating role of school engagement in linking these perceived peer relationships with academic and non-academic outcomes. The sample comprised 1,436 high-school students (670 boys, 756 girls; 711 early adolescents, 723 later adolescents). Self-report measures and objective achievement tests were used. Structural equation modelling (SEM) was performed to test the hypothesized model and its invariance across gender and age groups. Perceived same-sex peer relationships yielded positive direct and indirect links with academic performance and general self-esteem. Perceived opposite-sex peer relationships yielded positive direct and indirect links with general self-esteem and an indirect positive link with academic performance, but mediation via school engagement was not as strong as that of perceived same-sex peer relationships. These findings generalized across gender and age groups. Adolescents' same-sex and opposite-sex peer relationships seem to positively impact their academic performance and general self-esteem in distinct ways. It appears that school engagement plays an important role in mediating these peer relationship effects, particularly those of same-sex peer relationships, on academic and non-academic functioning. Implications for psycho-educational theory, measurement, and practice are discussed. ©2011 The British Psychological Society.

    Adolescence is a critical phase of development and experimentation with delinquent behaviors. There is a growing body of literature exploring individual and structural impacts of discrimination on health outcomes and delinquent behaviors. However, there is limited research assessing how school diversity and discrimination impact students' delinquent behaviors. In response, the purpose of this study was to assess if individual- and school-level indicators of discrimination and diversity were associated with student delinquent behaviors among African American and White students. We analyzed Wave I (1994-1995) data from the National Longitudinal Study of Adolescent Health. Our analysis was limited to 8947 African American and White students (73% White, 48% male, and 88% parent ≥ high school education). We used multilevel zero-inflated negative binomial regression to test the association of individual- and school characteristics and discrimination with the number of self-reported delinquent behaviors. Race, sex, perceived peer inclusion, and teacher discrimination were predictors of students' delinquent behaviors. The average school perceived peer inclusion and percentage of African Americans in teaching roles were associated with delinquent behaviors. Findings from this study highlight the potential for intervention at the interpersonal and school levels to reduce delinquency among African American and White students. © 2018, American School Health Association.

  13. A single sex pheromone receptor determines chemical response specificity of sexual behavior in the silkmoth Bombyx mori.

    Full Text Available In insects and other animals, intraspecific communication between individuals of the opposite sex is mediated in part by chemical signals called sex pheromones. In most moth species, male moths rely heavily on species-specific sex pheromones emitted by female moths to identify and orient towards an appropriate mating partner among a large number of sympatric insect species. The silkmoth, Bombyx mori, utilizes the simplest possible pheromone system, in which a single pheromone component, (E, Z-10,12-hexadecadienol (bombykol, is sufficient to elicit full sexual behavior. We have previously shown that the sex pheromone receptor BmOR1 mediates specific detection of bombykol in the antennae of male silkmoths. However, it is unclear whether the sex pheromone receptor is the minimally sufficient determination factor that triggers initiation of orientation behavior towards a potential mate. Using transgenic silkmoths expressing the sex pheromone receptor PxOR1 of the diamondback moth Plutella xylostella in BmOR1-expressing neurons, we show that the selectivity of the sex pheromone receptor determines the chemical response specificity of sexual behavior in the silkmoth. Bombykol receptor neurons expressing PxOR1 responded to its specific ligand, (Z-11-hexadecenal (Z11-16:Ald, in a dose-dependent manner. Male moths expressing PxOR1 exhibited typical pheromone orientation behavior and copulation attempts in response to Z11-16:Ald and to females of P. xylostella. Transformation of the bombykol receptor neurons had no effect on their projections in the antennal lobe. These results indicate that activation of bombykol receptor neurons alone is sufficient to trigger full sexual behavior. Thus, a single gene defines behavioral selectivity in sex pheromone communication in the silkmoth. Our findings show that a single molecular determinant can not only function as a modulator of behavior but also as an all-or-nothing initiator of a complex species

    To review the impact of sex education and HIV education interventions in schools in developing countries on both risk behaviours for HIV and the psychosocial factors that affect them. We conducted a systematic review. Searches identified studies in developing countries that evaluated interventions using either experimental or strong quasi-experimental designs and measured the impact of the intervention on sexual risk behaviours. Each study was summarized and coded, and the results were tabulated by type of intervention. Twenty-two intervention evaluations met the inclusion criteria: 17 were based on a curriculum and 5 were not, and 19 were implemented primarily by adults and 3 by peers. These 22 interventions significantly improved 21 out of 55 sexual behaviours measured. Only one of the interventions (a non-curriculum-based peer-led intervention) increased any measure of reported sexual intercourse; 7 interventions delayed the reported onset of sex; 3 reduced the reported number of sexual partners; and 1 reduced the reported frequency of sexual activity. Furthermore, 16 of the 22 interventions significantly delayed sex, reduced the frequency of sex, decreased the number of sexual partners, increased the use of condoms or contraceptives or reduced the incidence of unprotected sex. Of the 17 curriculum-based interventions, 13 had most of the characteristics believed to be important according to research in developed and developing countries and were taught by adults. Of these 13 studies, 11 significantly improved one or more reported sexual behaviours, and the remaining 2 showed non-significant improvements in reported sexual behaviour. Among these 13 studies, interventions led by both teachers and other adults had strong evidence of positive impact on reported behaviour. Of the 5 non-curriculum-based interventions, 2 of 4 adult-led and the 1 peer-led intervention improved one or more sexual behaviours. A large majority of school-based sex education and HIV

    Apolipoprotein E4 (apoE4) and female sex are risk factors for developing Alzheimer's disease. It is unclear whether apoE4 contributes to behavioral function at younger ages. Standard neuropsychological assessments [intelligence quotient (IQ), attention, and executive function] and a test developed in this laboratory (Memory Island test of spatial learning and memory) were used to determine whether E4 and sex affect neuropsychological performance in healthy primary school children (age 7-10). A medical history was also obtained from the mother to determine whether negative birth outcomes were associated with apoE4. Mothers of apoE4+ children were more likely to report that their newborn was placed in an intensive care unit. A sex difference in birth weight was noted among apoE4- (males > females), but not apoE4+, offspring. Conversely, among apoE4+, but not apoE4- children, there was a sex difference in the Wechsler Abbreviated Scale of Intelligence (WASI) vocabulary score favoring boys. ApoE4- girls had better visual recall than apoE4+ girls or apoE4- boys on the Family Pictures test. Finally, apoE4+, unlike apoE4-, children did not show spatial memory retention during the Memory Island probe trial. Thus, apoE4 may affect neurobehavioral performance, particularly spatial memory, and antenatal health decades before any clinical expression of neurodegenerative processes.

    The objective of this study was to explore whether the time at which sex education was provided had any impact on reported cases of unintended pregnancies. A cross-sectional survey of secondary school students and their teachers was conducted using self-administered questionnaires. The participants were 1,234 students aged 14-17 years and 46 teachers in 5 secondary schools in South Eastern Nigeria. The outcome measures were reported pregnancies within the last 3 years by type of school and class level; class level at the time of receiving sex education at school; and age at the time of receiving sex education at home. In all schools, sex education was provided at all the junior and senior secondary school levels (JSS and SSS, respectively). Overall, reported cases of unintended pregnancies were highest among the junior students. In the private schools, four in ten teachers reported pregnancies among JSS 3 students. Almost four in ten teachers in public schools reported pregnancies among JSS 2 students. Of all the students, about three in ten reported pregnancies among JSS 2 and 3 students respectively. At home, sex education was provided at the mean age of 16 years (SD ± 2.2). All participants cited financial need and marital promise as major predisposing factors. About four in ten students did not use contraceptives during their first sexual experience. This study highlights the need to introduce sex education much earlier, possibly before the JSS levels. At home, sex education may have greater impact if provided before the age of 14 years. Efforts should be made to address the factors predisposing to teenage pregnancy.

    Full Text Available This study explores Grade 4 school children’s experiences of cross-sex relationships in a co- educational farm school in uMgungundlovu district in South Africa. The aim is to understand if and how constructions of gender bear on young children’s social relations at the school. Informed by children’s geographies and new sociology of childhood studies, this study uses data from semi-structured interviews and photo-voice imagery based on a qualitative narrative study of three girls and three boys aged between 9 and 12 years. The study found that children’s experiences of cross-sex relationships were deeply entrenched in traditional discourses of masculinities and femininities. These rigidly constructed discourses of gender were found to constrain possibilities and fluidities with which children navigated places and spaces of cross- sex relationships in the school. The hegemonic regulatory power of gender norms was a yardstick, informing children’s organisation and performances of cross-sex relationships even if some children had developed creative ways of subverting dominant gender norms in how they navigated in cross-sex relationships. The study argues for the liberalisation of gender norms, in order to allow children to freely – without being constrained by their genitalia – take subject positions of gender in cross-sex relationships. This would promote sustainable equitable gender relations, as children learn how to engage in cross-sex relationships, beyond the constraining prescripts of dominant masculinities and femininities.

    De Avila, Elizabeth

    Issues of sexual assault have become pervasive across all social strata in American society. Citizens need to start having conversations regarding these issues. To combat the issue of sexual assault, children need to be educated regarding the multifaceted aspects of sex through sex education in order to understand consent and resources they have available to them. Utilizing grounded theory methodology, this thesis analyzes sex education literature provided to Palm Beach County Middle School students. Using Burke's theory of terministic screens and Foucauldian theories of power and control; an understanding of the ideological underpinnings of this literature and discourse were acquired. After analysis, suggestions for disclosure and sex education programs are provided.

    Full Text Available Abstract Background Gender disparities in China are concentrated in poor rural areas and among poor households. The difference in intelligence between boys and girls is less clear in rural China. The purpose of this paper was to assess sex differences in the intellectual function of early school-aged children in rural China. Methods One thousand seven hundred forty four early school-aged offspring of women who had participated in a prenatal supplementation trial with different combinations of micronutrients and continued to reside in two rural counties in China were followed. We measured their Full-Scale IQ (FSIQ, Verbal Comprehension Index (VCI, Working Memory Index (WMI, Perceptual Reasoning Index (PRI and Processing Speed Index (PSI using the Wechsler Intelligence Scale for Children (WISC-IV. Multilevel analyses were used to assess sex differences in intellectual functioning in 7-10-year-old children in rural China. Results Boys’ adjusted mean FSIQ score was 0.97 points higher (95 % CI: -2.22 − 0.28 than that of girls. Girls obtained higher mean WMI and PSI scores, with 1.32 points (95 % CI: 0.14 − 2.51 and 3.10 points (95 % CI: 1.82–4.38 higher adjusted means, respectively. Boys’ adjusted mean VCI and PRI scores were significantly higher than those of girls, and the mean differences were 2.44 points (95 % CI: 0.95 − 3.94 and 3.68 points (95 % CI: 2.36 − 5.01, respectively. Conclusions There is no evidence to suggest sex differences in the general intelligence of early school-aged children in rural China. However, a difference in general intelligence between 10-year-old boys and girls was evident. Girls and boys in rural China tended to show different specific cognitive abilities.

  5. Sex education in schools in Denmark. Does Foreningen for Familieplanlaegning (the Danish PPA) have a role to play?

    1991-05-01

    The Danish Foreningen for Familieplanlaegning (FF), planned parenthood, has a role to play as a watchdog for human sexuality education in schools and teacher training and development of educational material. Sex education has been in the school system since the 1900's, but in 1970 it was made compulsory. Sex education must be integrated in all subjects, and teacher or student may introduce a sex topic/question at any time. Minimum requirements are information on contraceptives and STD's. In 1970, the Curriculum Committee provided Guidelines for Sex Education in Public Schools which stated the following limitations for teachers: no vulgar terminology, no pupil counseling, no information on sexual intercourse techniques, and no erotic photographic material. In 1986, the Committee on Health and Sex Education was formed to work out subject and guide materials; these curriculum guidelines will be available in August 1991. FF was invited only to address the committee, at which time it was advised that teachers not lump health and sex together, and that specific issues such as sex anatomy, contraception, STD's, AIDs, and abortion be addressed as well as the rights of saying no, first sexual experiences, emotions and feelings, and being in love. After some insistence and negotiation, the final draft included more on sex education. The FF Education Committee plans to hold a 3-day training course for teachers at teacher training colleges in the Fall, 1991. One of the first tasks of the Sex Education Committee was to form a workshop with representatives from 10 schools. Their conclusions were that 1) the class teacher be responsible for sex education, 2) cross professional collaboration needs to be implemented with, for example, guest speakers who are homosexuals, prostitutes, AID's related persons. 3) Parents must be given information and sought out for advice. 4) The limitations in the 1970 Guidelines need to be cancelled. 5) Teacher training must be expanded and improved.

    Abstract Background The aim of this study was to analyze the association between overweight prevalence and socioeconomic status (SES) measured by complex SES index and single SES factors in Polish adolescents in respect to age and sex. Methods This cross-sectional study was conducted in 2010-2011. A total of 1,176 adolescents aged 13.0-18.9 years were included. The respondents were students of junior-high and high schools from northern, eastern and central Poland. Quota sampling by sex and age was used. The SES was determined by: place of residence, self-declared economic situation, and parental education level. Respondents with low, average or high SES index (SESI) were identified. The level of overweight was assessed using Polish and international standards. Results The odds ratio (OR) for overweight prevalence in the oldest girls (aged 17.0-18.9 years) with high SESI was 0.34 (95%CI:0.13-0.92; P socioeconomic status and prevalence of overweight was related to sex and age. The high socioeconomic status strongly lowered the risk of overweight prevalence in the oldest girls, but not in boys, irrespective of age. Maternal education level lowered risk of overweight prevalence in girls. PMID:25909059

    Greater 'empowerment' of women in India, measured by their education and autonomy, is associated with a reduction in the extent to which their sons' educational attainment exceeds that of their daughters. Improving both father's and mother's education increases the educational attainment of daughters more than that of sons, but raising mother's education is associated with a significantly greater reduction of the difference in attainment between sons and daughters. In families in which the mother has completed primary education, the average difference between boys and girls in years spent in school is almost a third of a year lower than it is where the mother has less education. A one-standard-deviation increase in mother's autonomy is associated with an increase in daughter's schooling of more than half a month but has no correlation with son's education. The findings highlight the importance of women's empowerment for the intergenerational transfer of equality in educational attainment of the sexes.

    The purpose of this study was to evaluate salary differences between male and female academic radiologists at U.S. medical schools. Laws in several U.S. states mandate public release of government records, including salary information of state employees. From online salary data published by 12 states, we extracted the salaries of all academic radiologists at 24 public medical schools during 2011-2013 (n = 573 radiologists). In this institutional review board-approved cross-sectional study, we linked these data to a physician database with information on physician sex, age, faculty rank, years since residency, clinical trial involvement, National Institutes of Health (NIH) funding, scientific publications, and clinical volume measured by 2013 Medicare payments. Sex difference in salary, the primary outcome, was estimated using a multilevel logistic regression adjusting for these factors. Among 573 academic radiologists, 171 (29.8%) were women. Female radiologists were younger (48.5 vs 51.6 years, p = 0.001) and more likely to be assistant professors (50.9% [87/171] vs 40.8% [164/402], p = 0.026). Salaries between men and women were similar in unadjusted analyses ($290,660 vs $289,797; absolute difference, $863; 95% CI, -$18,363 to $20,090), and remained so after adjusting for age, faculty rank, years since residency, clinical trial involvement, publications, total Medicare payments, NIH funding, and graduation from a highly ranked medical school. Among academic radiologists employed at 24 U.S. public medical schools, male and female radiologists had similar annual salaries both before and after adjusting for several variables known to influence salary among academic physicians.

    2008-06-01

    Adolescents display sexual behaviours and developmental characteristics that place them at risk for Sexually Transmitted Diseases (STDs). Because young people experiment sexually and because of the consequences of indiscriminate sexual activities on the youth, there is the need to mount sex education programmes that are geared towards enlightenment and appropriate education about sex and sexuality. To determine whether Sex Education Intervention Programme would reduce at-risk sexual behaviours of school-going adolescents. Pre-test, post-test control group quasi-experimental design. A randomly selected co-educational school in Ilorin Metropolis, Nigeria. 24 school-going adolescents aged 13-19 years. Sex Education Programme (treatment group) versus Control programme (placebo). Self-reported exposure to sexually transmitted diseases, multiple sex partners, anal sex, oral sex, non use of condom. When the treatment (intervention) group was compared with the control group in an intention to treat analysis, there were significant differences in at-risk sexual behaviours of the two groups. Those in the intervention group reported less at-risk sexual behaviours than their counterparts in the control group. The treatment group evaluated the intervention programme positively and their knowledge of sexual health improved. Lack of behavioural effect on the control group could be linked to differential quality of delivery of intervention. Compared with the control group, this specially designed intervention sex education programme reduced at-risk sexual behaviour in adolescents. Based on this finding, it was recommended that sex education be introduced into the curriculum of secondary school education in Nigeria.

    This paper describes an evaluation of possible changes in sexual behavior in adolescents who participated in a school-based sex education program in selected public schools in four municipalities in the state of Minas Gerais, Brazil. The program is inserted within the context of reproductive rights, deals with risks involved in unsafe sexual practices and focuses on the positive aspects of sexuality. A quasi-experimental design with pre and post-tests and a non-equivalent control group was used to evaluate the intervention. A total of 4,795 questionnaires were included in this analysis. The program succeeded in more than doubling consistent condom use with casual partners and in increasing the use of modern contraceptives during last intercourse by 68%. The intervention had no effect on age at first intercourse or on adolescents' engagement in sexual activities. The sex education program was effective in generating positive changes in the sexual behavior of adolescents, while not stimulating participation in sexual activities.

    We aimed to provide process and effectiveness evaluations of a sex education intervention realized with interactive techniques in high schools of Pavia (Italy). Six public high schools, divided into 'treated' and 'control' units, voluntarily joined this mixed-methods study. Only second-year classes were enrolled: treated adolescents followed a sex education course, performed by trained 'near-peer educators' (undergraduate medical students) with interactive techniques. All adolescents compiled an anonymous effectiveness evaluation questionnaire at baseline (pre-test) and 3 months later (post-test). Sexual knowledge and reported behavioural changes were compared between the two groups through linear mixed-effects models. The process was assessed through a satisfaction questionnaire for treated students, monitoring cards for working group members and cards/diaries for educators. The final sample consisted of 547 treated and 355 control adolescents (mean age = 15.28 ± 0.61 years). Highly significant changes (p knowledge items. No significant changes for behavioural items were reported. Process evaluation showed positive results in adolescents' satisfaction, highlighting the need for more youth gathering places. Working group members and educators generally provided positive evaluations, although difficult communication was perceived. The intervention was effective in improving adolescents' sexual knowledge. The present work highlighted that in Italy sex education in adolescence is still neglected: this could encourage misinformation and health-risk behaviour. Young people perceive the need for a serious health-promoting action in which they could play an active role, spreading educational messages with organized interactive methods. © The Author(s) 2015.

    In this study, we investigated if a single-item indicator measured the degree to which people were open about their same-sex attraction ("out") as accurately as a multi-item scale. For the multi-item scale, we used the Outness Inventory, which includes three subscales: family, world, and religion. We examined correlations between the single- and multi-item measures; between the single-item indicator and the subscales of the multi-item scale; and between the measures and internalized homonegativity, social attitudes towards homosexuality, and depressive symptoms. In addition, we calculated Tjur's R (2) as a measure of predictive power of the single-item indicator, multi-item scale, and subscales of the multi-item scale in predicting two health-related outcomes: depressive symptoms and condomless anal sex with multiple partners. There was a strong correlation between the single- and multi-item measures (r = 0.73). Furthermore, there were strong correlations between the single-item indicator and each subscale of the multi-item scale: family (r = 0.70), world (r = 0.77), and religion (r = 0.50). In addition, the correlations between the single-item indicator and internalized homonegativity (r = -0.63), social attitudes towards homosexuality (r = -0.38), and depression (r = -0.14) were higher than those between the multi-item scale and internalized homonegativity (r = -0.55), social attitudes towards homosexuality (r = -0.21), and depression (r = -0.13). Contrary to the premise that multi-item measures are superior to single-item measures, our collective findings indicate that the single-item indicator of outness performs better than the multi-item scale of outness.

    Body dissatisfaction is now recognized as having considerable negative impact on social, psychological, and physical health, particularly in adolescent girls. Consequently, we have developed a six-session co-educational body image intervention (Happy Being Me Co-educational) designed to reduce body dissatisfaction and its risk factors in Grade 7 girls. In addition to evaluating the program's efficacy, we aimed to identify whether girls would benefit equally when it was delivered as a universal intervention to a whole class including both boys and girls (co-educational delivery), or delivered as a selective intervention to girls only (single-sex delivery). Participants were 200 Grade 7 girls from five schools in Melbourne, Australia. Schools were randomly allocated to receive the intervention in single-sex classes (n=74), co-educational classes (n=73), or participate as a no-intervention control (n=53). Girls completed self-report assessments of body dissatisfaction, psychological (internalization of the thin ideal, appearance comparison, and self-esteem) and peer environment (weight-related teasing and appearance conversations) risk factors for body dissatisfaction, and dietary restraint, at baseline, post-intervention, and at 6-month follow-up. Significant improvements in body dissatisfaction and psychological risk factors were observed in the intervention group at post-intervention and these were maintained at follow-up for psychological risk factors. Importantly, no significant differences between universal and selective delivery were observed, suggesting that the intervention is appropriate for dissemination in both modes.

    Sex differences in relational and overt aggression among 3rd (n=176), 4th (n=179), and 5th graders (n=145) from three public schools (n=500; 278 girls) were examined. Nominations of relational aggression increased over time among 4th and 5th grade girls, but not among boys or 3rd grade girls. Among 3rd graders, boys received more nominations for relational aggression than girls. By the end of the 5th grade, girls received more relational aggression nominations than boys. There was also a significant rise in nominations of overt aggression among 5th grade girls, but not among 5th grade boys or younger boys and girls. As expected, boys were more likely than girls to be nominated for overt aggression at all grade levels. The findings are helpful for explaining inconsistencies of earlier research pertaining to sex differences in relational aggression and for advancing our understanding of the causes of aggression.

    In the early 1960's liberal and socialist groups laid claim to an unbiased sexual education in the public school system. Conservative groups responded with demands for a more rigid sexual education, of which a memorial signed by a number of Swedish physicians, 140 läkares hemställan till Konungen om atgärder för förstärkt karaktärsfostran m.m (140 physicians' petition to His Majesty the King for actions for a reinforced education of character, etc) drew most public attention. Against the background of an increased number of persons infected with venereal diseases, and of the many unmarried young mothers, the physicians meant that school education should make clear that sex was a part of marriage and that abstinence was the only acceptable prophylactic. Furthermore, they maintained that Christian faith should be emphasised as a rule of conduct and that the Swedish parliament should act in order to strengthen censorship regarding sex in the medias. After being published, the memorial was severely criticised mainly by the larger national newspapers. However, provincial newspapers, as well as the Christian and conservative press, defended the memorial, and eventually, the debate came to circle around the dominant position of radical press regarding moral issues. The petition came to have some importance for the founding of the political party Kristen demokratisk samling ("Christian democrats' movement"). However, partly due to the etition, a governmental inquiry into the matter of sexual education was enacted, resulting in the shaping of an education quite the opposite of what the physicians had demanded.

    The purpose of this study was to investigate the effects of a sexuality education coaching program given to elementary school students in terms of sex-related knowledge and attitude. The participants were elementary school students in S city (Experimental group=21, Control group=23). Data were collected and the program was conducted from Feb. 15 to Apr. 15, 2013. The experimental group of 21 elementary school students in the fifth and sixth grades who received the sexuality education coaching program, 10 sessions in the three weeks. The control group of 23 elementary school students in the fifth and sixth grades from another school received, 2 sessions in the three weeks on sexuality education including physiology and sexual abuse prevention. Data were analyzed using χ²-test, independent t-test, repeated measures ANOVA, and utilized the SPSS program. The experimental group showed significantly better sex-related knowledge and sex-related attitudes than the control group. Therefore, individualized approach with emphasis on the differences of their level of understanding and strengths should be considered in providing sexuality education coaching programs for elementary school students.

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people.

    In France, the National Education system has attributed an important health and sex education role to its teachers, based on a global and positive vision of sexuality Parents, teachers, public services and specialized resources each have a role to play in sex education for children and adolescents so that each young person can receive an education allowing him or her to enjoy a healthy sexuality. This study investigated the individual representations of sexuality, declared practices and knowledge of junior high schoolchildren and Section d'Enseignement G6n6ral et Professionnel Adapt6 (SEGPA) students, a structure for children with serious learning difficulties. The study methodology was based on administration of questionnaires (n = 524) to the two cohorts concerned. The secondary objective was to compare these two populations and identify the specificities of SEGPA pupils. The conclusions of this study should allow adults in charge of sex education in junior high schools and SEGPA to adapt sex education tools.

    2017-01-01

    Research on adolescent best friendships typically focuses on school-based friendships, ignoring important differences between classroom-based and out-of-school friendships. With data from 156 ninth-grade students, many of whom named more than 1 best friend across the 14-day period, the authors examined associations between the daily school context of one's best friendship and adjustment. Benefits of in-grade best friendships were found in academic engagement when a composite was assessed across the 2-week period. Daily findings were more complex and were different between weekends and school days. Out-of-grade best friends were named more frequently on weekends, and on weekend days in which they named an out-of-school best friend participants spent more time with that friend but felt like less of a good student. Implications for our understanding of friendship context and for the measurement of friendship itself are discussed.

    Some studies have demonstrated that the Cattell-Horn-Carroll (CHC) cognitive abilities influence writing; however, little research has investigated whether CHC cognitive abilities influence writing the same way for males and females across grades. We used multiple group structural equation models to investigate whether CHC cognitive ability influences on written expression differed between grades or sex using the Kaufman Assessment Battery for Children, Second Edition and the Kaufman Tests of Educational Achievement, Second Edition co-normed standardization sample data (N=2117). After testing for consistent measurement of cognitive abilities across grades and sex, we tested whether the cognitive ability influences on written expression were moderated by grade level or sex. An important developmental shift was observed equally across sex groups: Learning Efficiency (Gl) influences decreased whereas Crystallized Ability (Gc) influences increased after fourth grade. Further, Short-Term Memory (Gsm) and Retrieval Fluency (Gr) influences on written expression depended on sex at grades 1-4, with larger Gr influences for females and larger Gsm influences for males. We internally replicated our main findings using two different cognitive explanatory models, adding further support for the developmental and sex-based differential cognitive ability influences on writing. Explanatory cognitive models of writing need to incorporate development, and possibly, sex to provide an expanded understanding of writing development and guard against potential generalizability issues characteristic of special population (i.e., male-female) studies.

  11. Voices of successful science teachers in an urban diverse single gender girls' school

    Science.gov (United States)

    Malhan, Jyoti

    This research study was conducted as a qualitative case study of four successful science teachers of female students in a diverse, title 1, urban, public girls' school. The study was designed to hear the 'muted' voices of successful science teachers concerning their beliefs and practices when they effectively provide learning opportunities for female students of color in their classrooms. Ethic of Care, equity pedagogy and culturally responsive pedagogy, created the theoretical framework for interpretation of the powerful narratives and storytelling that influenced this group of successful teachers. Data were collected by conducting in-depth, semi-structured interviews. Constant comparative method and narrative analysis were used to code and categorize the data. Analysis was conducted after each interview to discover emergent themes. Teachers conducted member checks throughout the process. The findings from the study yielded the following: (1) teachers had a passion for science and incorporated ongoing scientific developments and real-life examples and applications in their teaching, (2) teachers adopted a caring, concerned, and student-centered approach to teaching, (3) teachers acknowledged certain benefits to a single-sex girls education which included fewer distractions, increased confidence and comfort level of students, (5) teachers built relationships with students that encouraged students to engage with rigorous course content and meet higher expectations for performance. Themes that emerged included: care, culturally responsive pedagogy and culturally relevant curriculum.

    Shamai, S; Coambs, R B

    1992-01-01

    This paper evaluates intervention programs in schools using the theoretical framework of the critical sociology of education, and most specifically, the extent to which schools are autonomous from the larger society. Three different types of intervention programs are reviewed: drug abuse prevention, sex education, and programs to change gender stereotypes, all of which were found to have limited effectiveness. Schools appear unable to change behaviors which are prevalent in a culture because they themselves are strongly influenced by that culture, and because adolescents are influenced by forces outside school. To be effective, such interventions would seem to require governmental agencies, community groups, and the media to work with the schools in order to influence the culture and thus produce behavioral changes in individuals.

  14. Sex and the Island”: Lives of Single Women in Prince Edward Island

    Directory of Open Access Journals (Sweden)

    Kristie Collins

    2011-05-01

    Full Text Available This article considers the significance attributed to Prince Edward Island in managing a marginalized single female identity, as presented by accounts of thirty never-married and previously-married Island women, aged twenty-seven through sixty-five. As popular media and social narratives overwhelmingly position contemporary single women against an urban backdrop, the question arises as to whether unmarried Island women feel “marooned” in ways their urban counterparts may not. In accordance with feminist aims to produce research for, rather than about, women’s lives, the paper focuses on two themes from fieldwork interviews that were of particular interest to participants. The first theme relates to negotiating female singleness within the Island’s family-centered culture, and the second theme presents participants’ talk around advantages and disadvantages of living in Prince Edward Island, Canada, as single women. The paper concludes with a summary of other findings from the study and suggestions for future research on female singleness and island locales.

  15. Who Has the Advantage? Race and Sex Differences in Returns to Social Capital at Home and at School*

    A growing body of literature suggests that social capital is a valuable resource for children and youth, and that returns to that capital can increase academic success. However, relatively little is known about whether youth from different backgrounds build social capital in the same way and whether they receive the same returns to that capital. We examine the creation of and returns to social capital in family and school settings on academic achievement, measured as standardized test scores, for white boys, black boys, white girls, and black girls who were seniors in high school in the United States. Our findings suggest that while youth in different groups build social capital in largely the same way, differences exist by race and sex as to how family social capital affects academic achievement. Girls obtain greater returns to family social capital than do boys, but no group receives significant returns to school social capital after controlling for individual- and school-level characteristics.

    2015-01-01

    This paper reports on fieldwork carried out in 2011 with the aim of investigating the attitudes and reported behaviour of Congolese high school students concerning sexual relationships. A total of 56 boys and girls aged 16-20 from two urban and two rural high schools in South Kivu Province took part in focus groups, and 40 of these were subsequently interviewed individually. The majority of boys felt that they were entitled to sex from their girlfriends and that if persuasion was unsuccessful, the use of force was legitimate; this, in their minds, did not constitute rape. Girls, on the other hand, were clear that such forced sex was rape. However it may be understood, rape was perceived as having increased in recent years and was explained by weak legal systems, pornography and provocative dressing by girls. Boys were angry at the competition from older, often married, men who were able to provide monetary and other incentives to the girls.

    A better understanding is needed of the variables that may influence the risk of experiencing coerced sex among adolescent females in Sub-Saharan Africa. Data were collected from 700 female respondents who were interviewed in 2010 and 2012 waves of a longitudinal study of behavioral risk for HIV infection among youth aged 13-14 or 18-19 and living in two towns in southeastern Ghana. A series of logistic regression models examined the influences of household composition and wealth, four family process variables (behavioral control, relationship quality, financial support, conflict), school enrollment and relationship experience on females' risk of experiencing coerced sex. Eighteen percent of respondents reported having experienced coerced sex prior to Wave 1, and 13% experienced it between Waves 1 and 2. In both cross-sectional and prospective models, the variable with the strongest association with having experienced coerced sex was having ever had a boyfriend (fully adjusted odds ratios, 4.5 and 2.6, respectively). In cross-sectional analyses, parental behavioral control was negatively associated with risk for coerced sex, while parental conflict was positively associated; these associations were not significant in the prospective analyses. Having a boyfriend appears to be the primary predictor of coerced sex among young females, beyond any influence of family, school or other household variables. More research is needed to understand the context of females' relationships with boyfriends in an effort to reduce the risk of sexual coercion and to promote the prevention of sexual violence perpetrated by males within these relationships.

    Song, Michael M; Jones, Betsy G; Casanova, Robert A

    2016-01-01

    Sex- and gender-based medicine (SGBM) aims to (1) delineate and investigate sex- and gender-based differences in health, disease, and response to treatment and (2) apply that knowledge to clinical care to improve the health of both women and men. However, the integration of SGBM into medical school curricula is often haphazard and poorly defined; schools often do not know the current status of SGBM content in their curricula, even if they are committed to addressing gaps and improving SGBM delivery. Therefore, complete auditing and accounting of SGBM content in the existing medical school curriculum is necessary to determine the baseline status and prepare for successful integration of SGBM content into that curriculum. A review of course syllabi and lecture objectives as well as a targeted data analysis of the Curriculum Management and Information Tool (CurrMIT) were completed prior to a real-time curriculum audit. Subsequently, six "student scholars," three first-year and three second-year medical students, were recruited and trained to audit the first 2 years of the medical school curriculum for SGBM content, thus completing an audit for both of the pre-clinical years simultaneously. A qualitative analysis and a post-audit comparative analysis were completed to assess the level of SGBM instruction at our institution. The review of syllabi and the CurrMIT data analysis did not generate a meaningful catalogue of SGBM content in the curriculum; most of the content identified specifically targeted women's or men's health topics and not sex- or gender-based differences. The real-time student audit of the existing curriculum at Texas Tech revealed that most of the SGBM material was focused on the physiological/anatomical sex differences or gender differences in disease prevalence, with minimal coverage of sex- or gender-based differences in diagnosis, prognosis, treatment, and outcomes. The real-time student scholar audit was effective in identifying SGBM content in

    2004-06-01

    This study assessed attitudes of high school students toward physical education with regard to sex and sport participation. A total of 440 sport participants (175 girls and 265 boys) and of 427 nonsport participants (227 girls and 200 boys), all of whom were 15 yr. old, voluntarily participated. The Attitudes Toward Physical Education Scale was administered to assess participants' attitudes toward physical education. The results of 2 x 2 (Sex x Sports Participation) analysis of variance indicated a significant difference in attitudes toward physical education between sport participants and nonsport participants, with the former scoring higher, and a difference between boys and girls, with boys scoring higher. However, there was no significant interaction between sex and sports participation on attitudes toward physical education. In general, sport participants had more favorable Attitudes Toward Physical Education scores than nonsport participants, and high school boys scored significantly higher than girls. There was a significant difference in Attitudes Toward Physical Education scores between female and male high school students, with boys having more favorable attitude scores.

    We follow the reductio ad absurdum reasoning described in the book "Sneaking a Look at God's Cards" by Giancarlo Ghirardi to demonstrate the wave-particle duality of light in a Mach-Zehnder interferometric setup analog to the conventional Young double-slit experiment. We aim at showing the double nature of light by measuring the existence of interference fringes down to the single-photon level. The setup includes a strongly attenuated laser, polarizing beam splitters, half-waveplates, polarizers and single-photon detectors.

    Health is vital to a child's learning in school and success in life. Therefore, early physical examination, and follow-up if necessary, would bring parents' attention to their child's health and would likely improve outcomes. The purposes of this study are twofold: to assess the health status of first-graders and to examine the health status differences between sexes, levels of residence urbanization, and quantity of available medical resources. This is a comparative descriptive study. Data from the 2002 Student Entry Physical Examination (SEPE) and Student Medical History Inventory (SMHI) were obtained from 203 public and private elementary schools in northern Taiwan where a population of 53,053 students was included. Frequencies, independent sample t test, one-way ANOVA along with Scheff's post hoc test, and Pearson's correlation were conducted using SPSS. This study showed that 13.7% of students had at least one diagnosed disease from the SMHI reported by parents. Moreover, the SEPE indicated that 79.5% students had at least one health concern. Dental caries, myopia, and obesity were the most prevalent health problems among the first-graders (69.6%, 27.1%, and 9.5%, respectively). Research results show that there were significant differences in the prevalence of dental caries, myopia, and obesity between different sexes and among levels of urbanization. However, the quantity of available medical resources made no significant difference. Elementary school entry physical examination is an important way to detect students' health problems. It is suggested that school health interventions consider students' health profiles along with their sex and level of urbanization in planning. More research is needed to find the risk factors of the health problems. Additionally, the creation of a school health committee is suggested to implement and evaluate the entry health examination program.

    The relationships of students' preadmission academic variables, sex, undergraduate major, and undergraduate institution to academic performance in medical school have not been thoroughly examined. To determine the ability of students' preadmission academic variables to predict osteopathic medical school performance and whether students' sex, undergraduate major, or undergraduate institution influence osteopathic medical school performance. The study followed students who graduated from New York College of Osteopathic Medicine of New York Institute of Technology in Old Westbury between 2003 and 2006. Student preadmission data were Medical College Admission Test (MCAT) scores, undergraduate grade point averages (GPAs), sex, undergraduate major, and undergraduate institutional selectivity. Medical school performance variables were GPAs, clinical performance (ie, clinical subject examinations and clerkship evaluations), and scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Clinical Evaluation (CE). Data were analyzed with Pearson product moment correlation coefficients and multivariate linear regression analyses. Differences between student groups were compared with the independent-samples, 2-tailed t test. A total of 737 students were included. All preadmission academic variables, except nonscience undergraduate GPA, were statistically significant predictors of performance on COMLEX-USA Level 1, and all preadmission academic variables were statistically significant predictors of performance on COMLEX-USA Level 2-CE. The MCAT score for biological sciences had the highest correlation among all variables with COMLEX-USA Level 1 performance (Pearson r=0.304; Posteopathic medical school performance, including GPAs, clinical performance, and COMLEX-USA Level 1 and Level 2-CE results. Clinical performance was predictive of COMLEX-USA Level 2-CE performance.

  6. Temperature-dependent sex determination in fish revisited: prevalence, a single sex ratio response pattern, and possible effects of climate change.

    Directory of Open Access Journals (Sweden)

    Natalia Ospina-Alvarez

    Full Text Available BACKGROUND: In gonochoristic vertebrates, sex determination mechanisms can be classified as genotypic (GSD or temperature-dependent (TSD. Some cases of TSD in fish have been questioned, but the prevalent view is that TSD is very common in this group of animals, with three different response patterns to temperature. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed field and laboratory data for the 59 fish species where TSD has been explicitly or implicitly claimed so far. For each species, we compiled data on the presence or absence of sex chromosomes and determined if the sex ratio response was obtained within temperatures that the species experiences in the wild. If so, we studied whether this response was statistically significant. We found evidence that many cases of observed sex ratio shifts in response to temperature reveal thermal alterations of an otherwise predominately GSD mechanism rather than the presence of TSD. We also show that in those fish species that actually have TSD, sex ratio response to increasing temperatures invariably results in highly male-biased sex ratios, and that even small changes of just 1-2 degrees C can significantly alter the sex ratio from 1:1 (males:females up to 3:1 in both freshwater and marine species. CONCLUSIONS/SIGNIFICANCE: We demonstrate that TSD in fish is far less widespread than currently believed, suggesting that TSD is clearly the exception in fish sex determination. Further, species with TSD exhibit only one general sex ratio response pattern to temperature. However, the viability of some fish populations with TSD can be compromised through alterations in their sex ratios as a response to temperature fluctuations of the magnitude predicted by climate change.

    Sex education is provided routinely to school-aged children in many countries without enough evidence that it will benefit them when they become adults. The purpose of this study was to examine the long-term influence of the sex education that was provided during the school-aged years on the attitudes, behaviors, and sexual health among male and female college students in Korea. For this descriptive, comparative study, the data were obtained from 3609 male and 2180 female college students by using the proportional quota sampling method. Overall, the female students had more opportunities for sex education. Receiving this education during the school-aged years lowered the sexual double standard score but was not related to sexual activity among the male and female students. Receiving sex education at different time points during the school-aged years had differential influences on the sexual attitudes and indicators of sexual health between the male and the female students. The results of this study suggest extending the role of school nurses to include redesigning the content of sex education programs, based on the sex and age of the students, and using midwives to provide sex education in community settings. © 2011 Blackwell Publishing Asia Pty Ltd.

    High school athletes are increasingly encouraged to participate in 1 sport year-round to increase their sport skills. However, no study has examined the association of competition volume, club sport participation, and sport specialization with sex and lower extremity injury (LEI) in a large sample of high school athletes. Increased competition volume, participating on a club team outside of school sports, and high levels of specialization will all be associated with a history of LEI. Girls will be more likely to engage in higher competition volume, participate on a club team, and be classified as highly specialized. Cross-sectional study. Level 3. High school athletes completed a questionnaire prior to the start of their competitive season regarding their sport participation and previous injury history. Multivariable logistic regression analyses were used to investigate associations of competition volume, club sport participation, and sport specialization with history of LEI, adjusting for sex. A cohort of 1544 high school athletes (780 girls; grades 9-12) from 29 high schools completed the questionnaire. Girls were more likely to participate at high competition volume (23.2% vs 11.0%, χ 2 = 84.7, P sport, or who were highly specialized had greater odds of reporting a previous LEI than those with low competition volume (odds ratio [OR], 2.08; 95% CI, 1.55-2.80; P sport participation (OR, 1.50; 95% CI, 1.20-1.88; P sport volume, on a club team, or being highly specialized was associated with history of LEI. Girls were more likely to participate at high volumes, be active on club teams, or be highly specialized, potentially placing them at increased risk of injury. Youth athletes, parents, and clinicians should be aware of the potential risks of intense, year-round participation in organized sports.

    Metoidioplasty represents one of the variants of phalloplasty in female transsexuals. Its main characteristic is that it is a one-stage procedure. It involves lengthening and straightening of hypertrophied clitoris to create a neophallus, urethral lengthening to enable voiding while standing, and scrotal reconstruction with insertion of testicle prostheses. Our aim is to describe our technique and highlight its advantages. Between September 2002 and April 2007, 82 female transsexuals, aged 18-54 years (mean age 31) underwent one-stage metoidioplasty. Clitoris is lengthened and straightened by division of clitoral ligaments and short urethral plate. Urethroplasty is done with combined buccal mucosa graft and genital skin flaps. Scrotum is created from labia majora in which two testicle prostheses are inserted. Simultaneously, female genitalia are removed. Patients' personal satisfaction about sensitivity and length of neophallus, possibility to void in standing position, real length of reconstructed urethra as well as complication rate comparing to other published data. The median follow-up was 32 months (range 14-69). The mean neophallic length was 5.7 cm (range 4-10). Voiding in standing position was reported in all patients, while dribbling and spraying were noticed in 23 cases and solved spontaneously. There were two urethral strictures and seven fistulas that required secondary minor revision. All patients reported preserved sensation and normal postoperative erection. Testicle prostheses rejection was not observed in any of the patients. Metoidioplasty is a single-stage and time-saving procedure. It could be an alternative to total phalloplasty in female transsexuals who do not wish to have sexual intercourse. Also, it represents a first step in cases where additional augmentation phalloplasty is required.

  13. THE IMPACT OF SEX EDUCATION ON TEENAGE PREGNANCY IN BASIC SCHOOLS OF BAWKU MUNICIPAL DISTRICT IN GHANA

    2017-11-01

    Full Text Available The incidence of teenage pregnancy has been on the rise in Ghana, especially in the Bawku-East Municipality. In Ghana adults rarely discussed sexual matters with the youth. Thus, the youth have little or no information about the biological changes that take place in their bodies during the transitional period from youth to adulthood. This has resulted in unplanned pregnancies for the vast majority of teenagers, which have serious developmental and socioeconomic implications. The study was to explore how sex education could mitigate teenage pregnancy in the Bawku-East Municipality. A total sample size of one hundred and twenty-five (125 respondents was used for the study. Questionnaires, in-depth interviews, focus group discussions and observation were used to collect data for the study. The study revealed that poor parenting, poverty and peer influence were the major causes of teenage pregnancy in the study area. In addition, concealing sex education and sex-knowledge from the youth made them more curious and vulnerable. There is the need for parents and schools to empower the youth through sex education to equip them with knowledge in order to overcome the potentially corrupt information through the social media and friends. The study will be useful to students, parents, teachers and vulnerable group (girl-child advocates in communities.

    In tephritids, the sex-determination pathway follows the sex-specific splicing of transformer (tra) mRNA, and the cooperation of tra and transformer-2 (tra-2) to effect the sex-specific splicing of doublesex (dsx), the genetic double-switch responsible for male or female somatic development. The Dominant Male Determiner (M) is the primary signal that controls this pathway. M, as yet uncharacterized, is Y-chromosome linked, expressed in the zygote and directly or indirectly diminishes active TRA protein in male embryos. Here we first demonstrated the high conservation of tra, tra-2 and dsx in two Australian tephritids, Bactrocera tryoni and Bactrocera jarvisi. We then used quantitative reverse transcription PCR on single, sexed embryos to examine expression of the key sex-determination genes during early embryogenesis. Individual embryos were sexed using molecular markers located on the B. jarvisi Y-chromosome that was also introgressed into a B. tryoni line. In B. jarvisi, sex-specific expression of tra transcripts occurred between 3 to 6 h after egg laying, and the dsx isoform was established by 7 h. These milestones were delayed in B. tryoni lines. The results provide a time frame for transcriptomic analyses to identify M and its direct targets, plus information on genes that may be targeted for the development of male-only lines for pest management. © 2014 The Royal Entomological Society.

    Do individual differences in the brain mechanisms for arithmetic underlie variability in high school mathematical competence? Using functional magnetic resonance imaging, we correlated brain responses to single digit calculation with standard scores on the Preliminary Scholastic Aptitude Test (PSAT) math subtest in high school seniors. PSAT math scores, while controlling for PSAT Critical Reading scores, correlated positively with calculation activation in the left supramarginal gyrus and bilateral anterior cingulate cortex, brain regions known to be engaged during arithmetic fact retrieval. At the same time, greater activation in the right intraparietal sulcus during calculation, a region established to be involved in numerical quantity processing, was related to lower PSAT math scores. These data reveal that the relative engagement of brain mechanisms associated with procedural versus memory-based calculation of single-digit arithmetic problems is related to high school level mathematical competence, highlighting the fundamental role that mental arithmetic fluency plays in the acquisition of higher-level mathematical competence.

    Adolescence is a highly dynamic period characterised by rapid growth and development. Adolescents have limited knowledge about sexual and reproduction health, and know little about the natural processes of puberty, sexual health, pregnancy or reproduction. Sex education should be an integral part of the learning process beginning in childhood and continuing into adult life, because it is lifelong process. This study was carried out to identify the knowledge and attitude of imparting sex education in school going adolescents in rural and urban area of Ambala district. A cross sectional study design was used to study the knowledge of reproductive and sexual health among school going children. A total of 743 adolescents from age group of 13-19 year were studied, using self designed semi-structured questionnaire to assess the knowledge regarding reproductive and sexual health among adolescents. The mean age of study subjects was 15.958±1.61 years, majority of adolescents i.e., 93.5% favour sex education. An 86.3% said sex education can prevent the occurrence of AIDS and 91.5% of adolescents prefer doctors should give them sex education followed by 83.0% school/teacher and least preference was parents 37.3%. There were substantial lacunae in the knowledge about reproductive and sexual health. Students felt that sex education is necessary and should be introduced in the school curriculum.

    Black and Latino young men who have sex with men (YMSM) are at disproportionate risk for sexually transmitted diseases (STDs), including HIV. This study informs school-centered strategies for connecting YMSM to health services by describing their willingness, perceived safety, and experiences in talking to school staff about sexual health. Cross-sectional data were collected from Black and Latino YMSM aged 13-19 through web-based questionnaires (N = 415) and interviews (N = 32). School nurses were the staff members youth most often reported willingness to talk to about HIV testing (37.8%), STD testing (37.1%), or condoms (37.3%), but least often reported as safe to talk to about attraction to other guys (11.4%). Interviews revealed youth reluctance to talk with school staff including nurses when uncertain of staff members' perceptions of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) people or perceiving staff to lack knowledge of LGBTQ issues, communities, or resources. Nurses may need additional training to effectively reach Black and Latino YMSM. © The Author(s) 2014.

    2013-04-01

    Full Text Available OBJECTIVE: Alcohol and other drug use appears to reduce decision-making ability and increase the risk of unsafe sex, leading to possible unplanned pregnancies, sexually transmitted diseases/human immunodeficiency virus/HIV transmission, and multiple sexual partners. This study aimed to test the hypothesis that risky sexual behaviors among adolescents are associated with legal and illegal drug use. METHODS: A national cross-sectional survey of 17,371 high-school students was conducted in 2010. Students were selected from 789 public and private schools in each of the 27 Brazilian state capitals by a multistage probabilistic sampling method and answered a self-report questionnaire. Weighted data were analyzed through basic contingency tables and logistic regressions testing for differences in condom use among adolescents who were sexually active during the past month. RESULTS: Approximately one third of the high school students had engaged in sexual intercourse in the month prior to the survey, and nearly half of these respondents had not used a condom. While overall sexual intercourse was more prevalent among boys, unsafe sexual intercourse was more prevalent among girls. Furthermore, a lower socioeconomic status was directly associated with non-condom use, while binge drinking and illegal drug use were independently associated with unsafe sexual intercourse. CONCLUSION: Adolescent alcohol and drug use were associated with unsafe sexual practices. School prevention programs must include drug use and sexuality topics simultaneously because both risk-taking behaviors occur simultaneously.

    School-based deworming is widely implemented in various countries to reduce the burden of soil-transmitted helminths (STHs), however, the frequency of drug administration varies in different settings. In this study, we compared the impact of a single annual treatment and 4-monthly treatment over a follow-up among Kenyan school children, and investigated the factors associated with residual infection. We performed a secondary analysis of data from a randomized trial investigating whether deworming for STHs alters risk of acquiring malaria. Children received either a single treatment or 4-monthly albendazole treatments were followed longitudinally from February 2014 to October 2014. The relative impact of treatment and factors associated with residual infections were investigated using mixed-effects regression models. Predisposition to infection was assessed based on Spearman's rank and Kendall's Tau correlation coefficients. In the 4-monthly treatment group, the proportion of children infected with hookworm decreased from 59.9 to 5.7%, while Ascaris lumbricoides infections dropped from 55.7 to 6.2%. In the single treatment group, hookworm infections decreased over the same time period from 58.7 to 18.3% (12.6% absolute difference in reduction, 95% CI: 8.9-16.3%), and A. lumbricoides from 56.7 to 23.3% (17.1% absolute difference in reduction, 95% CI: 13.1-21.1%). There was strong evidence for predisposition to both STH types. Residual hookworm infection among children on 4-monthly treatment were associated with male sex and baseline nutritional status, whereas A. lumbricoides infection was associated with individual and school-level infection at baseline, latrine cleanliness at schools. This study found that 4-monthly treatment w more effective than single annual treatment. Repeated treatments led to dramatic reductions in the intensities of STHs, but did not completely clear infections among school children in Kenya, a presumed reflection of reinfection in a setting

    Full Text Available The aim of the paper is a comparison of psychological readiness of the child to go to school in nuclear and single parent families. To obtain the objectives of the paper the following methods were used: 1 methods “Two schools” by L.A Venger to identify the level of formation of internal position of the student; 2 the method “Motivational research studies in older preschoolers” by M.R. Ginsburg; 3 method “Pattern” by L.I. Tsehanskaya to determine the degree of development of skills training activities; 4 method “Graphic dictation” by D. El’konin to study the ability to follow adult instructions. The investigated group consisted of 40 students from first grade secondary school - 20 students from nuclear families (12 girls and 8 boys and 20 students from single parent families (9 girls and 11 boys. As a result of qualitative, comparative and correlation analysis it was shown that readiness of children to go to school susbstantially depends on completness of their families. The children from families have a higher level of skill training and internal position than children from single parent families. This occurs because both parents pay more attention to the children in the forming of a willingness to learn in school. The studies have shown that in the group of children from nuclear families dominate the highest level of development of skills training activities, increased formation of internal positions and childrens social motivation. These indicators are the hallmarks of readiness to learn at school. Also, some recommendations to teachers are provided as for increase of motivation to learn in children from single parent families.

    Full Text Available The perception of the value of themselves as individuals is a very important outcome in childhood. The aim of this paper is to study the influence of specific domain self-perception on the self-esteem of school age children from Buenos Aires City/AR (CABA. The Self-Perception Profile for Children was administered to 219 children of both genders (mean age = 10.34; SD = 1.77 from a private school from CABA. Multiple lineal regression analysis were performed. School grade and sex differences were taken into account. The main predictor of self-esteem for the boys is the self-perception of physical appearance and for the girls the self-perception of social acceptance. Considering grade differences, the main predictor of self-esteem for children from third to fifth grade is the self-perception of physical appearance and for sixth and seventh graders the self-perception of social acceptance and behavior.

    Full Text Available Background: Aggression affects academic learning and emotional development, can damage school climate and if not controlled early and may precipitate extreme violence in the future. Objective s : (1 To determine the magnitude and types of aggressive behavior in school children. (2 To identify the influence of age and sex on aggressive behavior. Materials and Methods: A cross-sectional study was conducted in Anandanagar High School, Singur village, West Bengal. Participants were 161 boys and 177 girls of classes VII to IX. The students were asked to complete a self-administered questionnaire indicating the types of aggressive behavior by them in the previous month and to assess themselves with reference to statements indicating verbal/physical aggression. Results: Overall, 66.5% of the children were physically aggressive in the previous month: Boys 75.8%, girls 58.2% ( P = 0.001; 56.8% were verbally aggressive: Boys 55.2%, girls 61% ( P = 0.97. Verbal indirect passive aggression was more common among girls (55.3% than among boys (22.3% ( P = 0.000 [1.17E-09 ]. Boys were more liable to physical aggression, viz. 60.2% of the boys would hit on provocation compared with only 9% of the girls ( P = 0.000 [6.6E -23 ]. Regarding attributes indicating verbal aggression, girls were more argumentative (63.8% than boys (55.2% ( P = 0.134 and disagreeing (41.8% compared with boys (33.5% ( P = 0.145. With increasing age/class, physical direct active aggression decreased while physical indirect passive and verbal indirect passive aggression increased. No classes had been taken on anger control/management by school the authorities. Conclusions: Aggressive behavior was common both among boys and girls. Life skills education/counseling/classroom management strategies are recommended.

    To examine sex differences in psychosocial impairment associated with eating disorder features (EDF) in adolescents. Questionnaires that assessed EDF (extreme dietary restriction, objective binge eating, subjective binge eating, purging, excessive exercise, and weight/shape overvaluation) and psychosocial impairment (general psychological distress and quality of life) were completed by a school-based sample of adolescent males (n = 531) and females (n = 1135) in the Australian Capital Territory region of Australia. Each of the EDF assessed was associated with significant impairment in both male and female participants and this was the case for measures of both general psychological distress and quality of life, the only exception being that subjective binge eating was associated with elevated levels of distress in girls but not boys. The occurrence of subjective binge eating was associated with greater impairment in quality of life in girls than in boys. Otherwise, the effects of EDF on psychosocial functioning did not differ by sex. The prevalence of most EDF was higher in girls than in boys, although EDF were not uncommon in boys. There appear to be few differences between male and female adolescents in terms of psychosocial impairment associated with EDF. The findings support the need for preventive interventions that seek to reduce the adverse impact of EDF in both boys and girls. The logistic and policy challenges inherent in such efforts warrant greater consideration. Further research is needed to elucidate the help-seeking behavior of young men with EDF who experience psychosocial impairment. © 2015 Wiley Periodicals, Inc.

    There are different structures of male and female brain as it caused the difference of spatial and mathematical ability. This study examined whether there was different geometry strategic competence between sexes. There were 60 students given scholastic task of geometry strategic competence. The score obtained was analyzed by using independent t-test to compare the mean value of score between two groups. To determine the natural differences in strategy use between sexes, the score obtained was classified into high, medium, and low level. Semi-structured interview was conducted to six students (3 girls and 3 boys) who represented each level as subjects. By quantitative analyzing, obtained that there was no different in geometry strategic competence between girl and boy. Further, by qualitative analyzing known that girl students had more positive attitude than boys toward mathematics problem in the low score level and had the same strategic competence with boys in the medium scorelevel. Then, in the high scorelevel, boy students were tend to use insight strategies to solve problems whereas girls likely to use algorithm strategies.

    Brooks, Tanisha

    Many girls continue to achieve below their male counterparts and portray negative attitudes towards science classes. Some school districts are using single-gender education as a way to shrink the gender gap in school achievement and science related attitude. The purpose of this study was to compare achievement and science-related attitudes of 7th grade girls in single-gender education to 7th grade girls in mixed-gender education. The theoretical base for this study included knowledge from brain-based learning and assimilation, accommodation and age factors of Piaget's theory of cognitive development. The 12-week study included 48 7th grade girls, 21 in the single-gender classroom and 14 in each mixed-gender classroom. This quantitative randomized posttest only control group design utilized the TerraNova Science Assessment and the Test of Science Related Attitudes. Analysis of Variance (ANOVA) was used to determine if significant differences existed in the achievement and attitudes of girls in single and mixed-gender science classes. ANOVA analyses revealed that the girls in the single-gender classroom showed a significantly higher achievement level when compared to girls in the mixed-gender classrooms. Results showed no significant difference in attitude between the two groups. The results of this study contribute to social change by raising awareness about gender issues in science achievement and attitude, addressing a deficiency in the single-gender science education literature, and assisting educational systems in decision making to address achievement gaps while moving toward adequate yearly progress and meeting the requirements of the No Child Left Behind Act of 2001.

    Full Text Available School-based sex education is a cornerstone of HIV prevention for adolescents who continue to bear a disproportionally high HIV burden globally. We systematically reviewed and meta-analyzed the existing evidence for school-based sex education interventions in low- and middle-income countries to determine the efficacy of these interventions in changing HIV-related knowledge and risk behaviors.We searched five electronic databases, PubMed, Embase, PsycInfo, CINAHL, and Sociological Abstracts, for eligible articles. We also conducted hand-searching of key journals and secondary reference searching of included articles to identify potential studies. Intervention effects were synthesized through random effects meta-analysis for five outcomes: HIV knowledge, self-efficacy, sexual debut, condom use, and number of sexual partners.Of 6191 unique citations initially identified, 64 studies in 63 articles were included in the review. Nine interventions either focused exclusively on abstinence (abstinence-only or emphasized abstinence (abstinence-plus, whereas the remaining 55 interventions provided comprehensive sex education. Thirty-three studies were able to be meta-analyzed across five HIV-related outcomes. Results from meta-analysis demonstrate that school-based sex education is an effective strategy for reducing HIV-related risk. Students who received school-based sex education interventions had significantly greater HIV knowledge (Hedges g = 0.63, 95% Confidence Interval (CI: 0.49-0.78, p<0.001, self-efficacy related to refusing sex or condom use (Hedges g = 0.25, 95% CI: 0.14-0.36, p<0.001, condom use (OR = 1.34, 95% CI: 1.18-1.52, p<0.001, fewer sexual partners (OR = 0.75, 95% CI:0.67-0.84, p<0.001 and less initiation of first sex during follow-up (OR = 0.66, 95% CI: 0.54-0.83, p<0.001.The paucity of abstinence-only or abstinence-plus interventions identified during the review made comparisons between the predominant

    Approximately 300,000 U.S. adolescents sustain concussions annually while participating in organized athletics. This study aimed to track sex and sport-specific trends among high school sports-related concussions over time, to identify whether a particular sport predisposes athletes to a higher risk, and to assess whether traumatic brain injury law enactments have been successful in improving recognition. Injury data for academic years 2005 to 2014 were collected from annual reports generated by High School RIO (Reporting Information Online). The relative proportions of total estimated concussions to total estimated injuries were compared using an injury proportion ratio. The concussion rate was defined as the number of concussions per 10,000 athlete exposures (1 athlete participating in 1 practice or competition), with rates compared using a rate ratio. To evaluate the impact of legislation on sports-related concussions in this population, trends in concussion rates and proportions were analyzed before enactment (academic years 2005-2009) and after enactment (academic years 2010-2014). Between 2005-2006 and 2014-2015, a significant increase (p adolescent athletes can have devastating consequences, and we now know that female athletes, especially girls' soccer players, may be at an even greater risk for sustaining this injury than all other athletes. Knowledge of the trends identified by this study may help lead to policy and prevention measures that can accommodate each sport effectively and potentially halt these trends.

  14. A Single Transcriptome of a Green Toad (Bufo viridis Yields Candidate Genes for Sex Determination and -Differentiation and Non-Anonymous Population Genetic Markers.

    Directory of Open Access Journals (Sweden)

    Jörn F Gerchen

    Full Text Available Large genome size, including immense repetitive and non-coding fractions, still present challenges for capacity, bioinformatics and thus affordability of whole genome sequencing in most amphibians. Here, we test the performance of a single transcriptome to understand whether it can provide a cost-efficient resource for species with large unknown genomes. Using RNA from six different tissues from a single Palearctic green toad (Bufo viridis specimen and Hiseq2000, we obtained 22,5 Mio reads and publish >100,000 unigene sequences. To evaluate efficacy and quality, we first use this data to identify green toad specific candidate genes, known from other vertebrates for their role in sex determination and differentiation. Of a list of 37 genes, the transcriptome yielded 32 (87%, many of which providing the first such data for this non-model anuran species. However, for many of these genes, only fragments could be retrieved. In order to allow also applications to population genetics, we further used the transcriptome for the targeted development of 21 non-anonymous microsatellites and tested them in genetic families and backcrosses. Eleven markers were specifically developed to be located on the B. viridis sex chromosomes; for eight markers we can indeed demonstrate sex-specific transmission in genetic families. Depending on phylogenetic distance, several markers, which are sex-linked in green toads, show high cross-amplification success across the anuran phylogeny, involving nine systematic anuran families. Our data support the view that single transcriptome sequencing (based on multiple tissues provides a reliable genomic resource and cost-efficient method for non-model amphibian species with large genome size and, despite limitations, should be considered as long as genome sequencing remains unaffordable for most species.

    1994-04-01

    To determine whether children requiring special education represent a high-risk group for identifying Tourette's syndrome (TS), we performed direct examinations for the presence of tics in 35 special education and 35 regular classroom students from a single school district. Of the special education students, nine (26%) had definite or probable tics as compared with only two (6%) of the regular classroom students. About one-third of the students with tics currently meet diagnostic criteria for TS and probably more will do so in the future. About one-half of the subjects with tics have evidence of obsessive-compulsive behavior (OCB) or an attention-deficit hyperactivity disorder (ADHD). For three randomly selected students with definite tics, direct examinations of first-degree relatives revealed the presence of tics in all families. Subjects to the limitations of this pilot study, we conclude that TS and related tic disorders are commonly associated with the need for special education in this single school district. TS might also be an important contributor to school problems in the childhood population at large and may be a highly prevalent condition. In addition, we conclude that childhood tics are associated with OCB and ADHD, are genetically determined, and are part of the TS clinical spectrum.

    School-based sex education is a cornerstone of HIV prevention for adolescents who continue to bear a disproportionally high HIV burden globally. We systematically reviewed and meta-analyzed the existing evidence for school-based sex education interventions in low- and middle-income countries to determine the efficacy of these interventions in changing HIV-related knowledge and risk behaviors. We searched five electronic databases, PubMed, Embase, PsycInfo, CINAHL, and Sociological Abstracts, for eligible articles. We also conducted hand-searching of key journals and secondary reference searching of included articles to identify potential studies. Intervention effects were synthesized through random effects meta-analysis for five outcomes: HIV knowledge, self-efficacy, sexual debut, condom use, and number of sexual partners. Of 6191 unique citations initially identified, 64 studies in 63 articles were included in the review. Nine interventions either focused exclusively on abstinence (abstinence-only) or emphasized abstinence (abstinence-plus), whereas the remaining 55 interventions provided comprehensive sex education. Thirty-three studies were able to be meta-analyzed across five HIV-related outcomes. Results from meta-analysis demonstrate that school-based sex education is an effective strategy for reducing HIV-related risk. Students who received school-based sex education interventions had significantly greater HIV knowledge (Hedges g = 0.63, 95% Confidence Interval (CI): 0.49-0.78, psex or condom use (Hedges g = 0.25, 95% CI: 0.14-0.36, psex during follow-up (OR = 0.66, 95% CI: 0.54-0.83, psex education interventions adapted from effective programs and those involving a range of school-based and community-based components had the largest impact on changing HIV-related behaviors.

    Full Text Available The aim of this research is to determine whether there is any statistically signifi cant diff erence in motor abilities of boys and girls of younger school age. The sample includes 76 examinees with 37 males and 39 females. All are 5th and 6 th graders of primary school. The evaluation of motor abilitied is based on 5 tests. Multivariant analysis of variance is applied for determination of diff erences within the whole system of motor tests, whereas univariant analysis of variance is used for determining diff erences in each motor test. According to the fi ndings, statistically signifi cant diff erences in motor abilities between boys and girls at the studied age can be noticed in the test 20 m running from fl ying start, which is in favour of boys and in the test sit and reach, in favour of girls, while the diff erences in other tests are not statistically signifi cant. Considering the evaluation of motor abilities, boys have statistically much better results in the speed of alternative movements and explosive strenth, whereas girls have achieved much better results in the test for fl exibility. It has also been concluded that 5th and 6th graders have statistically better results in the space of coordination and explosive strenght, whereas girls are much better in the fi eld of fl exibility and suppleness.

    This study examined trends and patterns in public school teacher convictions in order to create a descriptive profile of teachers who have offended against their students. To accomplish this goal, the authors reviewed public records for demographic information as well as the history and frequency of teacher arrests and convictions in the southeastern United States from 2007 to 2011 and created an offender profile. Subsequent analyses were conducted to assess whether gender differences among sexual misconduct offenders existed in terms of the age of their alleged victim, the grade level in which they were employed at the time of arrest or indictment, and the manner by which their alleged crimes were revealed and charges were brought against them.

    Prevalence of adolescent sexual activity is on the increase globally, resulting in increased risk of adverse reproductive health outcomes among them. Sources of sex information are key factors that influence female adolescents' sexual decision-making. Consequently, this study is aimed at identifying adolescents' sources of sexuality information, and its likely effect on their sexual practices among in-school female adolescents in Osisioma LGA, in southeastern Nigeria. A total of 304 girls selected by multi-stage sampling technique were studied. Responses were elicited from them using pretested, semi-structured, self administered questionnaire. Data were analyzed using MS Excel and Epi-6. Primary and subsequent sources of sexuality information were mainly the media and peers. Families and schools mostly were not involved in provision of early sex education. Media and peer influence were predominantly negative. Female adolescents' knowledge of issues of sex was low. Premarital sex, early sexual initiation, and unprotected sex was common among them. Consequently, adverse implication of negative sexual behavior, such as unplanned pregnancies and induced abortion, was prevalent. The study highlights the need for increased roles of parents and teachers in early sexuality education of adolescent girls. This can be done by increasing capacity of parents to discuss sexuality issues with their children. Copyright © 2011 North American Society for Pediatric and Adolescent Gynecology.

    To assess acceptability of parents/guardians of adolescents towards the introduction of sex and reproductive health education in the community and schools. A multi-stage random sampling technique was used to get 150 participants for this study. A structured questionnaire was used to interview the sampled participants and was supplemented with guided focus group discussion in Kinondoni Municipality of Dar es Salaam, Tanzania. The analysis of the findings shows that there is a mixed feeling on the introduction of sex and reproductive health education in schools. Participants strongly supported that they should talk with their adolescents about sexuality and reproductive health (88.6%) but their culture prohibits them from doing so (76.7%). Also supported that condoms could protect against HIV/AIDS and sexually transmitted infections (82%), but strongly opposed the use of condoms to their adolescents because it would encourage promiscuity (78%). When the data were analysed by faith of the religions of the participants, 64% were in favour of introducing sex education and reproductive health, but were opposed to use of condoms to their adolescents. All participants were against vijiweni, which were recreation centres for the youths because they taught bad manners to their adolescents. The preferred source of information about sex education and reproductive health should be from the parents/guardians (86%), religious leaders (70%), media (62%), health workers (61%) and school teachers (59%). All in all the will of introduction of sex education and reproductive health in the community is there but the approach need to be worked out carefully by taking into account of the cultural and religious factors. Parents/guardians, religious leaders and traditional charismatic leaders should take part in designing the programme and even being involved in teaching it. The other option is to lump together sex education and reproductive health education in science especially in biology

  4. The impact of single-gender classrooms on science achievement of middle school gifted girls

    Ulkins, David S.

    Studies indicate a gap in science achievement and positive attitudes towards science between gifted male and female students with females performing less than the males. This study investigated the impact of a single-gender classroom environment as opposed to a mixed-gender classroom, on motivation, locus of control, self-concept, and science achievement of middle school gifted girls. The Motivated Strategies for Learning Questionnaire (MSLQ), Review of Personal Effectiveness with Locus of Control (ROPELOC), Test of Science Related Attitudes (TOSRA), and Stanford Achievement Test 10th Edition, were used to measure the dependent variables respectively. The independent-measure t test was used to compare the differences between girls in a single-gender classroom with the ones in a mixed-gender classroom. A significant difference in the external locus of control resulted for girls in the single gender classroom. However, there were no significant differences found in science achievement, motivation, and the attitudes toward science between the two groups. The implication is that a single-gender learning environment and the use of differentiated teaching strategies can help lessen the negative effects of societal stereotypes in today's classrooms. These, along with being cognizant of the differences in learning styles of girls and their male counterparts, will result in a greater level of success for gifted females in the area of science education.

    Full Text Available Peer-led sex education is widely believed to be an effective approach to reducing unsafe sex among young people, but reliable evidence from long-term studies is lacking. To assess the effectiveness of one form of school-based peer-led sex education in reducing unintended teenage pregnancy, we did a cluster (school randomised trial with 7 y of follow-up.Twenty-seven representative schools in England, with over 9,000 pupils aged 13-14 y at baseline, took part in the trial. Schools were randomised to either peer-led sex education (intervention or to continue their usual teacher-led sex education (control. Peer educators, aged 16-17 y, were trained to deliver three 1-h classroom sessions of sex education to 13- to 14-y-old pupils from the same schools. The sessions used participatory learning methods designed to improve the younger pupils' skills in sexual communication and condom use and their knowledge about pregnancy, sexually transmitted infections (STIs, contraception, and local sexual health services. Main outcome measures were abortion and live births by age 20 y, determined by anonymised linkage of girls to routine (statutory data. Assessment of these outcomes was blind to sex education allocation. The proportion of girls who had one or more abortions before age 20 y was the same in each arm (intervention, 5.0% [95% confidence interval (CI 4.0%-6.3%]; control, 5.0% [95% CI 4.0%-6.4%]. The odds ratio (OR adjusted for randomisation strata was 1.07 (95% CI 0.80-1.42, p = 0.64, intervention versus control.

    This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

    Previous neuroimaging studies in adults have revealed that first and second languages (L1/L2) share similar neural substrates, and that proficiency is a major determinant of the neural organization of L2 in the lexical-semantic and syntactic domains. However, little is known about neural substrates of children in the phonological domain, or about sex differences. Here, we conducted a large-scale study (n = 484) of school-aged children using functional near-infrared spectroscopy and a word repetition task, which requires a great extent of phonological processing. We investigated cortical activation during word processing, emphasizing sex differences, to clarify similarities and differences between L1 and L2, and proficiency-related differences during early L2 learning. L1 and L2 shared similar neural substrates with decreased activation in L2 compared to L1 in the posterior superior/middle temporal and angular/supramarginal gyri for both sexes. Significant sex differences were found in cortical activation within language areas during high-frequency word but not during low-frequency word processing. During high-frequency word processing, widely distributed areas including the angular/supramarginal gyri were activated in boys, while more restricted areas, excluding the angular/supramarginal gyri were activated in girls. Significant sex differences were also found in L2 proficiency-related activation: activation significantly increased with proficiency in boys, whereas no proficiency-related differences were found in girls. Importantly, cortical sex differences emerged with proficiency. Based on previous research, the present results indicate that sex differences are acquired or enlarged during language development through different cognitive strategies between sexes, possibly reflecting their different memory functions. © 2015 Wiley Periodicals, Inc.

    Social protection can reduce HIV-risk behavior in general adolescent populations, but evidence among HIV-positive adolescents is limited. This study quantitatively tests whether social protection is associated with reduced unprotected sex among 1060 ART-eligible adolescents from 53 government facilities in South Africa. Potential social protection included nine 'cash/cash-in-kind' and 'care' provisions. Analyses tested interactive/additive effects using logistic regressions and marginal effects models, controlling for covariates. 18 % of all HIV-positive adolescents and 28 % of girls reported unprotected sex. Lower rates of unprotected sex were associated with access to school (OR 0.52 95 % CI 0.33-0.82 p = 0.005), parental supervision (OR 0.54 95 % CI 0.33-0.90 p = 0.019), and adolescent-sensitive clinic care (OR 0.43 95 % CI 0.25-0.73 p = 0.002). Gender moderated the effect of adolescent-sensitive clinic care. Combination social protection had additive effects amongst girls: without any provisions 49 % reported unprotected sex; with 1-2 provisions 13-38 %; and with all provisions 9 %. Combination social protection has the potential to promote safer sex among HIV-positive adolescents, particularly girls.

    Background: Youth participation in organized sports in the United States is rising, with many athletes focusing on a single sport at an increasingly younger age. Purpose: To retrospectively compare single-sport specialization in current high school (HS), collegiate, and professional athletes with regard to the rate and age of specialization, the number of months per year of single-sport training, and the athlete’s perception of injury related to specialization. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A survey was distributed to HS, collegiate, and professional athletes prior to their yearly preparticipation physical examination. Athletes were asked whether they had chosen to specialize in only 1 sport, and data were then collected pertaining to this decision. Results: A total of 3090 athletes completed the survey (503 HS, 856 collegiate, and 1731 professional athletes). A significantly greater percentage of current collegiate athletes specialized to play a single sport during their childhood/adolescence (45.2% of HS athletes, 67.7% of collegiate athletes, and 46.0% of professional athletes; P < .001). The age of single-sport specialization differed between groups and occurred at a mean age of 12.7 ± 2.4 (HS), 14.8 ± 2.5 (collegiate), and 14.1 ± 2.8 years (professional) (P < .001). Current HS (39.9%) and collegiate athletes (42.1%) recalled a statistically greater incidence of sport-related injury than current professional athletes (25.4%) (P < .001). The majority (61.7%) of professional athletes indicated that they believed specialization helps the athlete play at a higher level, compared with 79.7% of HS and 80.6% of collegiate athletes (P < .001). Notably, only 22.3% of professional athletes said they would want their own child to specialize to play only 1 sport during childhood/adolescence. Conclusion: This study provides a foundation for understanding current trends in single-sport specialization in all athletic levels. Current

    Docosahexaenoic acid (DHA), supplied by the diet or endogenous biosynthesis from α-linolenic acid, accretes during the perinatal brain growth spurt. Results regarding a potential programming effect on cognitive function and behavior in humans are inconclusive. Here we aimed to investigate whether behavioral outcomes in childhood were associated with FADS tag-single-nucleotide polymorphisms (SNPs) previously found to have opposing effects on infant erythrocyte DHA. At 36 mo, we assessed psychomotor development with the third edition of the Ages & Stages Questionnaire (n = 256) and physical activity by accelerometry (n = 231) in children from the SKOT [Småbørns Kost Og Trivsel (Diet and Thriving in Young Children)] cohort. Blood samples were taken to determine erythrocyte DHA (n = 200), FADS tag-SNPs (n = 255), and PPARG-Pro12Ala (n = 255). All outcomes were analyzed in models, including all 3 SNPs, SNP-sex interactions, erythrocyte DHA at 36 mo, and covariates. As previously shown, the minor allele carriers of the FADS SNP rs1535 had increased erythrocyte DHA at 9 mo, whereas DHA decreased in minor allele carriers of rs174448 and rs174575 (effect size around 0.5 percentage points per allele). No overall effects were observed for any of the FADS SNPs on the outcomes reported here, but FADS SNP-sex interactions were found for a number of DHA-increasing FADS alleles on both communication and problem solving (P = 0.005 and 0.013). DHA-increasing FADS alleles resulted in reduced scores in girls and improved abilities in boys, with an effect size of ∼1 score-point/allele. No associations were found between current erythrocyte DHA and any of the behavioral outcomes. The P value for the triple interaction between DHA-increasing FADS alleles, PPARG, and sex for communication was 0.051, and subsequent analyses showed the FADS-sex interaction only in PPARG minor allele carriers (n = 70). Furthermore, FADS-PPARG interactions were seen for problem solving in boys and for

    Positive adolescent sexual health is supported by effective school-based sex education. Methods to promote positive sexual health need to reflect determinants of contraception intention, which must include understanding gender and age (year group) differences. To date, there has been limited theory-based exploration of these determinants in school age participants, placing limitations on sexual health educators to tailor learning most effectively. Cross-sectional survey data were collected from UK school pupils (n=1378) aged 12-16 years. Measures included theory of planned behaviour, prototype willingness, anticipated regret and knowledge items. Linear regression determined significant predictors of intention to use condoms, the oral contraceptive pill and emergency contraception (EC). The significance of differences by gender and school year was evaluated using t-tests and analysis of variance (ANOVA). Three distinct predictive models emerged for condom, pill and EC use, predicting 36%, 18% and 23% of variance respectively. Attitude, gender and anticipated regret for unprotected sex significantly predicted intention for all types of contraception (Psex education.

    Perdana University Graduate School of Medicine (PUGSOM), the first graduate-entry medical school in Malaysia, was established in 2011 in collaboration with Johns Hopkins University School of Medicine (JHUSOM), an American medical school. This study compared learning environments (LE) at these two schools, which shared the same overarching curriculum, along with a comparator Malaysian medical school, Cyberjaya University College of Medical Sciences (CUCMS). As a secondary aim, we compared 2 LE assessment tools - the widely-used Dundee Ready Educational Environment Measure (DREEM) and the newer Johns Hopkins Learning Environment Scale (JHLES). Students responded anonymously at the end of their first year of medical school to surveys which included DREEM, JHLES, single-item global LE assessment variables, and demographics questions. Respondents included 24/24 (100 %) students at PUGSOM, 100/120 (83 %) at JHUSOM, and 79/83 (95 %) at CUCMS. PUGSOM had the highest overall LE ratings (p safety" domains. JHLES detected significant differences across schools in 5/7 domains and had stronger correlations than DREEM to each global LE assessment variable. The inaugural class of medical students at PUGSOM rated their LE exceptionally highly, providing evidence that transporting a medical school curriculum may be successful. The JHLES showed promise as a LE assessment tool for use in international settings.

    Acute sleep deprivation can lead to judgement errors and thereby increases the risk of accidents, possibly due to an impaired working memory. However, whether the adverse effects of acute sleep loss on working memory are modulated by auditory distraction in women and men are not known. Additionally, it is unknown whether sleep loss alters the way in which men and women perceive their working memory performance. Thus, 24 young adults (12 women using oral contraceptives at the time of investigation) participated in two experimental conditions: nocturnal sleep (scheduled between 22:30 and 06:30 hours) versus one night of total sleep loss. Participants were administered a digital working memory test in which eight-digit sequences were learned and retrieved in the morning after each condition. Learning of digital sequences was accompanied by either silence or auditory distraction (equal distribution among trials). After sequence retrieval, each trial ended with a question regarding how certain participants were of the correctness of their response, as a self-estimate of working memory performance. We found that sleep loss impaired objective but not self-estimated working memory performance in women. In contrast, both measures remained unaffected by sleep loss in men. Auditory distraction impaired working memory performance, without modulation by sleep loss or sex. Being unaware of cognitive limitations when sleep-deprived, as seen in our study, could lead to undesirable consequences in, for example, an occupational context. Our findings suggest that sleep-deprived young women are at particular risk for overestimating their working memory performance. © 2018 The Authors.

    Increasing levels of polybrominated diphenyl ethers (PBDEs) in environmental and human samples has resulted in intensive discussion regarding possible hazard identification and risk assessment in the last years. In rodents, exposure to PBDE mixtures or single congeners has resulted in a mixed induction of CYP450- dependent enzymes, showing increased activity of hepatic EROD and PROD. In addition, genotoxicity has been observed in recombination assays, and neurotoxicity has been reported in mice exposed during development. Acute and sub-chronic exposures of mice and rats to a PBDE mixture (DE-71) cause dose-dependent reductions in serum concentrations of thyroxin (T4), and stressinduced elevations in plasma corticosterone. Further, some hydroxylated metabolites of PBDE congeners exhibit a higher potency in vivo than T4 in competitive binding to human transthyretin (TTR), the transport protein mediating transfer of thyroid hormones across the placenta and into the brain. The available information in the literature clearly indicates that PBDEs are potent neurotoxicants, causing effects at doses lower than that able to disrupt thyroid hormone profiles and change CYP 450 activities. Neurobehavior effects, which includes defects in learning and memory, and changes in nicotinic receptors were found at doses starting at 0.45 ppm in mouse (9). The congeners, PBDE 47 and PBDE 99, have also been shown to cause permanent aberrations in spontaneous behavior in mice which was more pronounced with increasing age. PBDE 47 is the most predominant congener found in environmental and human samples, including human breast milk. Its presence in breast milk highlights the importance of evaluating possible effects following early developmental exposure and because this period represents a critical time which an organism is extremely susceptible to minor changes in hormonal milieu. Variances in terms of time point and concentration of exposure to steroids can lead to an organizational

    Understanding the developmental pathways and sex differences in cigarette smoking behaviors in adolescents has the potential to positively impact substance abuse prevention and to reduce smoking-related health problems. Using data from the Unplugged school-based prevention trial, we investigated different patterns of smoking behavior development among secondary school students in the Czech Republic. Growth mixture modeling was used to examine different trajectories in cigarette smoking behaviors among male and female students (N=1874 6th graders; 50.4% male, mean age 11.8 years at baseline) participating in the Unplugged school-based randomized control trial for substance use prevention. A two-class model characterized cigarette use as a function of sex and Unplugged intervention status. More rapid cigarette use increases were observed in females (OR=1.17, p=0.01 in both rapid/moderate and slow smoking escalator classes) as compared to males. Further, in both classes, more rapid increases in smoking were observed for the control group as compared to the intervention group (OR=1.22, pprevention strategies aimed at adolescent females and early treatment programs for adolescent smokers to prevent increasing cigarette use with age.

    Past research has demonstrated consistent sex differences with men typically outperforming women on tests of spatial ability. However, less is known about intra-sex effects. In the present study, two groups of female students (physical education and non-physical education secondary students) and two corresponding groups of male students explored a large-scale virtual shopping centre. In a battery of tasks, spatial knowledge of the shopping centre as well as mental rotation ability were tested. Additional variables considered were circulating testosterone levels, the ratio of 2D:4D digit length, and computer experience. The results revealed both sex and intra-sex differences in spatial ability. Variables related to virtual navigation and computer ability and experience were found to be the most powerful predictors of group membership. Our results suggest that in female and male secondary students, participation in physical education and spatial skill are related.

    The Czechoslovak FPA (SPRVR) established in 1979 as a separate agency intends to maintain contact with the Ministry of Education in order to strengthen the position of parenthood education and influence the preparation of guidelines. The compulsory school system includes 6 to 15 year olds. After 1948, the head of the school determined the role of sex education and had the option of inviting a guest lecturer. In 1956, the Ministry of Education ruled that 1 sex education lecture was required for 14 year olds. In 1972, Government decision N137 required family life education at all school levels: pre-school stage, basic grades, secondary and higher education, and universities in preparation for harmonious, stable family life, parentship, and parenthood. In 1987, the new Minister of Education changed the prior policy of a separate secondary school subject to integration in other subjects. Due to this policy, there is great variation among schools, regions and teachers. Some emphasize the negative consequences of sex; personal experience and shame are also involved. Textbooks and materials are not uniform, and SPRVR is attempting to develop the resources to prepare sex materials and train unknowledgeable teachers. The Institute of Sexology since 1921 with its small staff has prepared texts and lecture notes and has a teaching staff but cannot meet the needs of the entire school population. New trends in sex education has emphasized the positive side of sex, behavior, and health, but have been met with parent and teacher apprehension and disagreement because of the mortality or the promotion of sex and a liberal attitude toward abortion. SPRVR holds scientific meetings on parenthood education with an interdisciplinary approach. There has been little consensus or uniformity of action, and inadequate sexual knowledge of teachers attitudes. The parenthood program also faces the influence of the Catholic Church which would like to abolish sex education.

    To use progress testing, a large bank of questions is required, particularly when planning to deliver tests over a long period of time. The questions need not only to be of good quality but also balanced in subject coverage across the curriculum to allow appropriate sampling. Hence as well as creating its own questions, an institution could share questions. Both methods allow ownership and structuring of the test appropriate to the educational requirements of the institution. Peninsula Medical School (PMS) has developed a mechanism to validate questions written in house. That mechanism can be adapted to utilise questions from an International question bank International Digital Electronic Access Library (IDEAL) and another UK-based question bank Universities Medical Assessment Partnership (UMAP). These questions have been used in our progress tests and analysed for relative performance. Data are presented to show that questions from differing sources can have comparable performance in a progress testing format. There are difficulties in transferring questions from one institution to another. These include problems of curricula and cultural differences. Whilst many of these difficulties exist, our experience suggests that it only requires a relatively small amount of work to adapt questions from external question banks for effective use. The longitudinal aspect of progress testing (albeit summatively) may allow more flexibility in question usage than single high stakes exams.

    Single-ventricle congenital heart disease (SVCHD) requires multiple palliative surgical procedures that leave visible surgical scars and physical deficits, which can alter body-image and self-esteem. This study aimed to compare sex and age differences in body-image, self-esteem, and body mass index (BMI) in adolescents and adults with SVCHD after surgical palliation with those of a healthy control group. Using a comparative, cross-sectional design, 54 adolescent and adult (26 male and 28 female) patients, age 15–50 years, with SVCHD were compared with 66 age-matched healthy controls. Body-image and self-esteem were measured using the Multidimensional Body-Self Relations Questionnaire–Appearance Scale and Rosenberg Self-Esteem Scale. Height and weight were collected from retrospective chart review, and BMI was calculated. Female adolescents and adult patients with SVCHD reported lower body image compared with males patients with SVCHD and healthy controls (p = 0.003). Specific areas of concern were face (p = 0.002), upper torso or chest (p = 0.002), and muscle tone (p = 0.001). Patients with SVCHD who were \\21 years of age had lower body image compared with healthy controls (p = 0.006). Self-esteem was comparable for both patients with SVCHD and healthy peers. There were no sex differences in BMI; BMI was higher in subjects[21 years of age (p = 0.01). Despite the similarities observed in self-esteem between the two groups, female patients with SVCHD\\21 years of age reported lower perceived body-image. Our findings support the need to recognize poor psychological adjustment related to low self-esteem in patients with SVCHD; female patients warrant increased scrutiny. Strategies to help patients with SVCHD cope with nonmodifiable aspects of body-image during the difficult adolescent–to–young adult years may potentially enhance self-esteem and decrease psychological distress.

    Physical activity in children is associated with better physical and mental health but many children do not meet physical activity guidelines. Friendship groups are potentially an important influence on children's physical activity and sedentary time. This paper examines the association between children of physical activity and sedentary time in school-based same-sex friendship networks, for both moderate-to-vigorous intensity physical activity (MVPA) and sedentary time. Moreover, considering the methodological challenges of conducting and interpreting these analyses, we provide examples of how to analyse these data and interpret results to encourage further work in the area. Accelerometer data for 1223 children, aged 8-9 years, were collected in 2015-2016 and analysed in 2017. Mean accelerometer minutes of MVPA and sedentary time were calculated. Children named up to four school friends and same-sex school-based friendship networks were constructed. Network models, which include correlation between friends, were fitted by sex. Both MVPA and sedentary time were found to be associated via the friendship networks, for both boys and girls. The network autocorrelation was 0.21 (95% CI: 0.15 to 0.26) for boys' MVPA, and 0.14 (95% CI: 0.07 to 0.21) for sedentary time. Network autocorrelation between girls was weaker, with 0.13 (95% CI: 0.06 to 0.19) for MVPA and 0.11 (95% CI: 0.05 to 0.17) for sedentary time. Physical activity and sedentary time of boys and girls are associated with the physical activity and sedentary time respectively of others within same-sex friendship networks, and these associations are comparable to other known factors. In this study, the correlation between friends was stronger for boys than girls, and stronger for MVPA than for sedentary time. These findings suggest that friendship networks play a part in understanding children's physical activity and sedentary time and could play a valuable role in developing effective interventions.

    An explanatory model for children's development of disruptive behavior across the transition from preschool to school was tested. It was hypothesized that child effortful control would mediate the effects of parenting on children's externalizing behavior and that child sex would moderate these relations. Participants were 241 children (123 boys) and their parents and teachers. Three dimensions of parenting, warm responsiveness, induction, and corporal punishment, were assessed via maternal report when children were 3 years old. Child effortful control at age 3 was measured using laboratory tasks and a mother-report questionnaire. Mothers and teachers contributed ratings of child externalizing behavior at age 6. Results showed that the hypothesized model fit the data well and that the pattern of associations between constructs differed for boys and girls. For boys, parental warm responsiveness and corporal punishment had significant indirect effects on children's externalizing behavior three years later, mediated by child effortful control. Such relations were not observed for girls. These findings support a sex-differentiated pathway to externalizing behavior across the transition from preschool to school.

    Full Text Available Purpose: In outbreaks of infectious disease, medical students are easily overlooked in the management of healthcare personnel protection although they serve in clinical clerkships in hospitals. In the early summer of 2015, Middle East respiratory syndrome (MERS struck South Korea, and students of Sungkyunkwan University School of Medicine (SKKUSOM were at risk of contracting the disease. The purpose of this report is to share SKKUSOM’s experience against the MERS outbreak and provide suggestions for medical schools to consider in the face of similar challenges. Methods: Through a process of reflection-on-action, we examined SKKUSOM’s efforts to avoid student infection during the MERS outbreak and derived a few practical guidelines that medical schools can adopt to ensure student safety in outbreaks of infectious disease. Results: The school leadership conducted ongoing risk assessment and developed contingency plans to balance student safety and continuity in medical education. They rearranged the clerkships to another hospital and offered distant lectures and tutorials. Five suggestions are extracted for medical schools to consider in infection outbreaks: instant cessation of clinical clerkships; rational decision making on a school closure; use of information technology; constant communication with hospitals; and open communication with faculty, staff, and students. Conclusion: Medical schools need to take the initiative and actively seek countermeasures against student infection. It is essential that medical schools keep constant communication with their index hospitals and the involved personnel. In order to assure student learning, medical schools may consider offering distant education with online technology.

    Full Text Available Oral health promotion through schools is recommended by the World Health Organization (WHO for improving knowledge, attitude, and behavior related to oral health and for prevention and control of dental diseases among school children. In low resource settings, it is important to develop evidence for health education methods in oral health behavioral practices. The objectives of this study were to assess both the baseline awareness and practices regarding oral hygiene and the impact of a single education session on the change in oral health behavior. A school based, cross-sectional study on 112 primary school children was conducted after obtaining the consent of the school authorities and parents. A pretested, structured proforma was used for baseline awareness and behavior regarding oral health. A 30 min educational session was imparted and after 1 month, and the oral health practices were reassessed to find out the impact of the education session. Baseline survey revealed the following findings. Self-reported dental problems were found in 48.22% of the children in the last 6 months. When asked about the risk factors for dental problems, 28.57% mentioned eating sweets followed by improper brushing, whereas 40.17% were not aware about any risk factor for dental problems. It was found that 28.57% of the children did not brush their teeth regularly, whereas 35.71% used a tooth-brush for brushing their teeth. After the intervention, it was observed that there was a significant improvement in the proportion of children using a toothbrush for cleaning their teeth and of those who rinsed their mouth after meals. In conclusion, even a single education session was found to be effective in bringing about a change in the oral health behavior of primary school children.

    Experimental and epidemiologic investigations suggest that certain pesticides may alter sex steroid hormone synthesis, metabolism or regulation, and the risk of hormone-related cancers. Here, we evaluated whether single-nucleotide polymorphisms (SNPs) involved in hormone homeostasis alter the effect of pesticide exposure on prostate cancer risk. We evaluated pesticide–SNP interactions between 39 pesticides and SNPs with respect to prostate cancer among 776 cases and 1,444 controls nested in the Agricultural Health Study cohort. In these interactions, we included candidate SNPs involved in hormone synthesis, metabolism or regulation (N = 1,100), as well as SNPs associated with circulating sex steroid concentrations, as identified by genome-wide association studies (N = 17). Unconditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Multiplicative SNP–pesticide interactions were calculated using a likelihood ratio test. We translated p-values for interaction into q-values, which reflected the false discovery rate, to account for multiple comparisons. We observed a significant interaction, which was robust to multiple comparison testing, between the herbicide dicamba and rs8192166 in the testosterone metabolizing gene SRD5A1 (p-interaction = 4.0 × 10−5; q-value = 0.03), such that men with two copies of the wild-type genotype CC had a reduced risk of prostate cancer associated with low use of dicamba (OR = 0.62 95% CI: 0.41, 0.93) and high use of dicamba (OR = 0.44, 95% CI: 0.29, 0.68), compared to those who reported no use of dicamba; in contrast, there was no significant association between dicamba and prostate cancer among those carrying one or two copies of the variant T allele at rs8192166. In addition, interactions between two organophosphate insecticides and SNPs related to estradiol metabolism were observed to result in an increased risk of prostate cancer. While replication is

The study included 13,368 babies by 13,165 women who had a single embryo transfer (SET) between 2002 and 2006. Logistic regression was used to model the effect on the sex ratio at birth of ART characteristics [in vitro fertilisation (IVF) or intracytoplasmic sperm insemination (ICSI) SET, cleavage-stage or blastocyst SET, and fresh or thawed SET] and biological characteristics (woman's and partner's age and cause of infertility). Proportion of male births. The crude sex ratio at birth was 51.3%. Individual ART procedures had a significant effect on the sex ratio at birth. More males were born following IVF SET (53.0%) than ICSI SET (50.0%), and following blastocyst SET (54.1%) than cleavage-stage SET (49.9%). For a specific ART regimen, IVF blastocyst SET produced more males (56.1%) and ICSI cleavage-stage SET produced fewer males (48.7%). The change in the sex ratio at birth of SET babies is associated with the ART regimen. The mechanism of these effects remains unclear. Fertility clinics and patients should be aware of the bias in the sex ratio at birth when using ART procedures. © 2010 The Authors Journal compilation © RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.

    To investigate the knowledge and sources of knowledge among Saudi female adolescent students, attending public and private schools in the city of Riyadh with regard to sexuality and reproductive health. This cross sectional survey was conducted from January to April 2009. Female adolescents between 11 and 21 years of age were invited to participate in the survey. Five classes of intermediate and secondary levels were randomly selected from 2 schools in Riyadh city. A total of 417 female students were included into the sample. Students were asked to answer a self-administrated questionnaire. Forty-two percent of the participants reported that they discussed sexual matters with their friends. Only 15.8% discussed these matters with their parents (mothers). Interestingly, 17.3% discussed sexual matters with the domestic helper. Most (61%) reported that their teachers had negative attitudes toward questions related to sexual issues. Only 33.3%, 37.9% and 14.5% knew that syphilis, gonorrhea, and hepatitis B, are sexually transmitted diseases. No significant differences were found between students in private schools and public schools. Formal sexual education should be introduced in the curriculum of the schools within the context of our religion and culture. Parents and teachers should be more open to discuss sexual issues with their children and students.

    Extracurricular involvement creates an outlet for adolescents to gain skills and resources that assist them in overcoming certain risks. Resiliency theory is applied to study the promotive effects of extracurricular activity involvement as this may help Polish youth overcome risks for alcohol use. Our data include 2903, 13 and 14 year old Polish adolescents. We use regression analysis to test the main and interaction effects of extracurricular involvement after adjusting for demographics and social influences. Sex differences are examined within the resilience framework. We found protective effects of extracurricular involvement for males, but only a compensatory effect for females. Implications for future research and intervention are discussed. Copyright © 2014 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

Based on these findings, we hypothesized that sex would similarly be associated with residual variation in human urine solutes. Sex-related effects on residuals might affect the establishment of physiological baselines and error in medical assays.We tested the effects of sex on residual variation in urine chemistry by estimating coefficients of variation (CV for urinary solutes in paired sequential 24-h urines (≤72 hour interval in 6,758 females and 9,024 males aged 16-80 submitted to a clinical laboratory.Females had higher CVs than males for urinary phosphorus overall at the False Discovery Rate (P0.3. Males had higher CVs for citrate (P<0.01 from ages 16-45 and females higher CVs for citrate (P<0.01 from ages 56-80, suggesting effects of an extant oestral cycle on residual variance.Our findings indicate the effects of sex on residual variance of the excretion of urinary solutes including phosphorus and citrate; differences in CV by sex might reflect dietary lability, differences in the fidelity of reporting or genetic differentiation in renal solute consistency. Such an effect could complicate medical analysis by the addition of random error to phenotypic assays. Renal analysis might require explicit incorporation of heterogeneity among factorial effects, and for sex in particular.

  15. Sex tourism in Thailand.

    Many foreigners visit Thailand in search of sex. While long-distance tourism was long enjoyed by members of more privileged social classes, even the lower economical classes of Japan, Malaysia, Europe, America, and Australia can now afford to travel over long distances. This relatively new breed of tourist is more likely to be of lower socioeconomic and educational status and less likely to use condoms when having sex. An estimated 30,000 sex workers are active in Bangkok, of whom 7000/10,000 are females who work specifically in the tourism sector. 1/2-1/3 of the 600 commercial sex establishments in the city are visited by foreigners. Phuket, Pattaya, Koh Samui, and Chiangmai are also well-frequented by sex tourists. Overall, a large, diverse, inexpensive, and accessible commercial sex market exists in Thailand. One may meet sex workers quasi-ubiquitously and be assured to find someone capable of meeting one's sexual needs. With these attributes, Thailand strongly attracts tourists in search of sex. A certain degree of recklessness also prevails among those on vacation. Away from the peers and social mores of their native lands, tourists may engage in sexually activities without criticism. Likewise, Thai sex workers who cater to foreigners, especially females, enjoy more freedom and control in sexual relations than their peers who work among nationals. Neither single nor married women in Thailand are allowed much sexual freedom and are traditionally expected to be obliging docile, and submissive. The greater than normal personal latitude enjoyed by both sex worker and foreigner lead to more negotiation on condom use and overall lower use. As such, Thailand's commercial sex market with foreigners' involvement therein threatens to spread HIV to many other countries throughout the world.

    This exploratory study examined the experiences of black and Latino teen young men who have sex with men (YMSM) and their preferences for communication with school staff about matters related to sexual orientation. Participants for this study were recruited in three urban centers in the United States and by multiple community-based organizations serving black and Latino YMSM. Eligible youth were male, black and Latino, ages 13–19, enrolled in 90 days of school in the previous 18 months, and reported attraction to or sexual behavior with other males, or identified as gay or bisexual. Participants completed web-based questionnaires (n=415) and/or in-depth interviews (n=32). Questionnaire participants reported willingness to talk to at least one school staff member about: safety, dating and relationships, and feeling attracted to other guys (63.4%, 58.4%, and 55.9%, respectively). About one-third of the sample reported they would not talk with any school staff about these topics. Exploratory analyses revealed youth who experienced feeling unsafe at school and who had higher levels of trust in the information provided by school staff were more likely to be willing to talk with school staff about safety issues, dating, or same sex attraction (adjusted odds ratio [AOR]=2.80 and AOR=4.85, respectively). Interview participants reported being most willing to talk to staff who were able and willing to help them, who would keep discussions confidential, and who expressed genuine care. Preferences for confiding in school staff perceived to be lesbian, gay, bisexual, and transgender (LGBT) and having similar racial/ethnic background were also noted. Findings suggest school staff can serve as points of contact for reaching YMSM and professional development and interventions can be tailored to reach YMSM and connect them to services they need. Additional research is needed to understand how to increase YMSM comfort talking with school staff about sexual health or sexual

    Elam, Jeanette H.

    The purpose of this study was to compare the academic performance of students enrolled in coeducational instruction and single-gender instruction. Within this framework, the researcher examined class type, gender, and racial/ethnicity using the sixth grade CRCT scores of selected students in the areas of mathematics and science. The fifth-grade mathematics and science scores for the same population were used to control for prior knowledge. This study examined the academic achievement of students based on class type, gender, and racial/ethnicity in relation to academic achievement. The study included the CRCT scores for mathematics and science of 6th-grade students at the middle school level who were tested during the 2007--2008 school year. Many studies conducted in the past have stressed females performed better in mathematics and science, while others have stated males performed better in the same areas. Yet, other studies have found conflicting results. A large Australian study (1996), compared the academic performance of students at single-gender and coeducational schools. The conclusion of this study indicated that both males and females who were educated in single-gender classrooms scored significantly higher than did males and females in coeducational classes. A study conducted by Graham Able (2003) documented superior academic performance of students in single-gender schools, after controlling for socioeconomic class and other variables. Able's most significant finding was that the advantage of single-gender schooling was greater for males in terms of academic results than for females. This directly contradicted the educational myth that males performed better in classrooms if females were present. The sample in this study consisted of CRCT scores for 304 sixth-grade students from four different middle schools. Due to the racial composition of the sample, the study only focused on black and white students. School 1 and School 2 involved single

    Full Text Available This study explores the experiences of urban African American males at a first year single-gender charter school in the Southern region of the United States. The present case study was based on interviews and focus groups with parents, teachers, students, and the school administrator, and a participant observation of Excel Academy [pseudonym]. The findings of this study suggest that there were four critical instructional complexities that emerged: expectations dissonance, disguised engagement, differential engagement, and expectations overload. Remarkably, these issues were being addressed by a school value created by students and institutionalized by teachers--To Never Quit. Recommendations to address each instructional complexity are explored.

    1998-01-01

    Preventing HIV infection and other sexually transmitted diseases (STDs), as well as sexual and physical violence, are major occupational health and safety concerns for prostitutes. Considerable evidence shows that anti-prostitution laws facilitate violence and abuse against prostitutes and may increase their risk of contracting HIV/STDs. For example, police often take advantage of existing laws against prostitution to demand money or sex. In general, the strict enforcement of anti-prostitution laws marginalizes prostitutes from services which could help them avoid abuse and promotes an environment in which prostitutes must take risks to avoid detection and arrest. One strategy to improve prostitutes' lives would therefore be to remove laws which prevent them from working safely and from travelling abroad to work legally. Projects in which prostitutes are actively involved have helped break down stereotypes against prostitutes, while police-sex worker liaison projects in Scotland and Australia have led to higher levels of reporting of crimes against prostitutes. The Network of Sex Work Projects (NSWP), an organization which links sex worker health programs around the world, has found that the incidence of HIV/STDs among prostitutes is lowest when they have control over their work conditions; access to condoms, lubricants, and other safe sex materials; and respect of their basic human and legal rights. People need to understand that consensual involvement in sex work is different from forced sex trafficking.

    Low caste adolescent girls living in rural northern Karnataka are at increased risk of school drop-out, child marriage, and entry into sex-work, which enhances their vulnerability to HIV, early pregnancy and adverse maternal and child health outcomes. This protocol describes the evaluation of Samata, a comprehensive, multi-level intervention designed to address these structural drivers of HIV risk and vulnerability. The Samata study is a cluster randomised controlled trial that will be conducted in eighty village clusters (40 intervention; 40 control) in Bijapur and Bagalkot districts in northern Karnataka. The intervention seeks to reach low caste girls and their families; adolescent boys; village communities; high school teachers and school governing committees; and local government officials. All low caste (scheduled caste/tribe) adolescent girls attending 7th standard (final year of primary school) will be recruited into the study in two consecutive waves, one year apart. Girls (n = 2100), their families (n = 2100) and school teachers (n = 650) will be interviewed at baseline and at endline. The study is designed to assess the impact of the intervention on four primary outcomes: the proportion of low caste girls who (i) enter into secondary school; (ii) complete secondary school; (iii) marry before age 15; and (iv) engage in sex before age 15. Observers assessing the outcomes will be blinded to group assignment. The primary outcome will be an adjusted, cluster-level intention to treat analysis, comparing outcomes in intervention and control villages at follow-up. We will also conduct survival analyses for the following secondary outcomes: marriage, sexual debut, pregnancy and entry into sex work. Complementary monitoring and evaluation, qualitative and economic research will be used to explore and describe intervention implementation, the pathways through which change occurs, and the cost-effectiveness of the intervention. This is an innovative

    To study the incidence of mandibular third molar impaction in relation to type and side of impaction, age and sex of patients and indications for its surgical removal through data collected from a single institute over a period of 3 and half years. The records of 1198 patients who underwent the surgical removal of impacted mandibular third molars were reviewed retrospectively. Records were divided into groups according to sex, age, type and side of impaction. Radiographs were studied to determine angular position of impacted mandible third molar. We found that there was a high incidence of mesioangular lower third molar impaction (33.97 %), highest number of patients were found in 15-30 years of age group (48.33 %), a left side (56.93 %) was more commonly involved, female predominance (63.44 %) was observed and recurrent pericoronitis (33.81 %) was the most common indication. Awareness of the indications for surgical removal of impacted mandibular third molar to the patients will help to avoid future risk of complications and morbidity associated with the same. This will not only help in saving time and money but also prevents the psychological trauma associated with delayed treatment. Removal of only symptomatic IMTM seems to be the logical choice in view of financial constraint in developing countries like India but at the same time early removal offers freedom from future complications in selected cases. So surgeons should apply a meticulous approach in selecting the patients for SRIMTM.

    Medical teaching aims to develop attitudes and behaviors underlying professional competence of future physicians. We investigated whether a mandatory course on scientific methodology in the second study year could affect students' attitudes toward science in medicine. In a longitudinal study, students (n = 241) enrolling in 2001-2002 academic year at a single medical school were followed up until graduation in 2006-2007. Each year, they filled out a Likert-type questionnaire of 18 statements evaluating attitude toward science. Direct influence of the course on students' attitudes was tested in a nonrandomized controlled trial with the 2006-2007 second year student cohort. Positive students' attitudes toward science increased during study years (mean [SD] score of the maximum score of 90): from 57.6 (6.0) in the first to 69.8 (10.4) in the sixth year. There was a significant trend of increase in attitudes with the years of study (cubic trend by polynomial contrasts analysis, P = 0.011). Attendance of a course on research methodology significantly increased positive attitudes (score, 67.0 [7.0] before and 70.8 [7.5] after course, P = 0.032 vs control group), regardless of grade point average. The intervention had an effect even when the influence of the initial attitude was accounted for (F1,140 = 9.25, P = 0.003; analysis of covariance). The attitude changes after the course was greatest in students with low initial attitude scores (Spearman rinitial score, score difference, -0.44). Medical students have positive attitudes toward science and scientific method in medicine. Attendance of a course on research methodology had positive short-term effect on students' attitudes toward science. This positive effect should be maintained by vertical integration of the course in the medical curriculum.

    2015-06-01

    The purpose of this review was to critically examine and summarize the impact of school-based interventions designed to facilitate the peer-related social competence of children with autism spectrum disorder (ASD). Reviewed studies employed a single-case experimental design, targeted peer-related social competence, included children 3-12 years old with an ASD, and took place in school settings. Articles were analyzed descriptively and using the evaluative method to determine study quality. Additionally, effect size estimates were calculated using nonoverlap of all pairs method and Tau-U. A total of 37 studies including 105 children were reviewed. Overall, ES estimates ranged from weak to strong, but on average, the reviewed interventions produced a moderate to strong effect, and quality ratings were generally in the acceptable to high range. Findings suggest that children with ASD can benefit from social skill interventions implemented with peers in school settings.

    People engaging in transactional sex are considered a key population for HIV prevention. Prior quantitative surveys demonstrated that behaviorally bisexual men in Vientiane, Laos commonly transact sex. In 2013, we conducted a qualitative study to explore behaviorally bisexual men's experience, motivations, and perceptions related to transactional sex in Vientiane. Behaviorally bisexual men were recruited from bars, nightclubs, and dormitories for five focus group discussions (FGDs) and 11 in-depth interviews (n = 31). Additionally, young women were recruited from a university, garment factory, and nightclub for four FGDs (n = 22). Transcripts were translated and thematically coded. Bisexual male participants most commonly described being paid for sex by male-to-female transgender people and buying sex from women. Both male and female participants reported that older, single women pay younger men for sex. Negotiation and direction of sexual transactions are influenced by age, attraction, and wealth. Common motivations for selling sex included the need for money to support family or fund school fees, material gain, or physical pleasure. Transactional sex was often opportunistic. Some behaviorally bisexual men reported selling sex in order to pay another more desirable sex partner or to buy gifts for their regular sex partner. Participants perceived high risk associated with intercourse with female sex workers but not with other transactional sex partners. Health interventions are needed to improve knowledge, risk perception, and health behaviors, but must recognize the diversity of transactional sex in Vientiane. Both physical and virtual settings may be appropriate for reaching behaviorally bisexual men and their partners.

    2012-01-01

    Results from a 2012 article showed a positive relationship between children’s body mass index (BMI) and energy intake at school-provided meals. To help explain that positive relationship, secondary analyses investigated 1) whether the relationship differed by sex and race, and 2) the relationship between BMI and six aspects of school-provided meals—amounts eaten of standardized portions, energy content given in trades, energy intake received in trades, energy intake from flavored milk, energy intake from a la carte ice cream, and breakfast type. Data were from four studies conducted one per school year (1999–2000 to 2002–2003). Fourth-grade children (n=328; 50% female; 54% Black) from 13 schools total were observed eating school-provided breakfast and lunch on one to three days per child for 1,178 total meals (50% breakfast). Children were weighed and measured. Marginal regression models were fit using BMI as the dependent variable. For Purpose One, independent variables were energy intake at school-provided meals, sex, race, age, and study; additional models included interaction terms involving energy intake and sex/race. For Purpose Two, independent variables were the six aspects of school-provided meals, sex, race, age, and study. The relationship between BMI and energy intake at school-provided meals differed by sex (p<0.0001; stronger for females) and race (p=0.0063; stronger for Black children). BMI was positively related to amounts eaten of standardized portions (p<0.0001) and negatively related to energy content given in trades (p=0.0052). Explaining the positive relationship between BMI and energy intake at school-provided meals may contribute to school-based obesity prevention efforts. PMID:23084638

    Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students' prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11-12 year-old students' standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students' prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students' grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement.

    To assess perceptions and attitudes regarding sex education among middle and high school teachers in Portugal. A study comprising 371 middle and high school teachers, both female and male, was conducted in Portugal in February and March 2006. Data was collected through snowball technique. The questionnaire was made up of two parts: the first collected data on demographics, career, religious background and training and experience in sex education; the second part presented three measures related to sex education, one assessed attitudes, another importance given to sex education, and the third the grade at which respondents believed sex education topics should be taught. The analysis of differences between gender, trained and untrained teachers in sex education, and experienced and non-experienced teachers in teaching sex education was carried out using ANOVA. Overall, teachers showed a fairly straightforward attitude towards sex education and assessed it as moderately/highly important. Body image was found to be the only topic that should be introduced in the 5th and 6th grades. Female teachers [F(1;366)=7.772;p=.006], trained teachers [F(1;351)=8.030; p=.005] and experienced teachers in teaching sex education [F(1;356)=30.836;p=.000] showed a more positive attitude towards sex education (M=39.5; 40.4; 41.3; respectively). Only trained teachers assessed its teaching as highly important [F(1;351)=5.436;p=.020]; and female teachers believed it should be introduced earlier [F(1;370)=5.412;p=0.021]. In general, teachers favor sex education in school. The fact that most topics of sex education are only taught in the 5th-6th or 7th-9th grades may have serious consequences since sex education has to be introduced before students engage in sexual behaviors.

    Pathogenic intestinal protozoa infections are common in school-aged children in the developing world and they are frequently associated with malabsorption syndromes and gastrointestinal morbidity. Since diagnosis of these parasites is difficult, prevalence data on intestinal protozoa is scarce. We collected two stool samples from school-aged children on Pemba Island, Tanzania, as part of a randomized controlled trial before and 3 weeks after treatment with (i) single-dose albendazole (400 mg); (ii) single-dose nitazoxanide (1,000 mg); (iii) nitazoxanide-albendazole combination (1,000 mg-400 mg), with each drug given separately on two consecutive days; and (iv) placebo. Formalin-fixed stool samples were examined for the presence of intestinal protozoa using an ether-concentration method to determine the prevalence and estimate cure rates (CRs). Almost half (48.7%) of the children were diagnosed with at least one of the (potentially) pathogenic protozoa Giardia intestinalis, Entamoeba histolytica/E. dispar and Blastocystis hominis. Observed CRs were high for all treatment arms, including placebo. Nitazoxanide showed a significant effect compared to placebo against the non-pathogenic protozoon Entamoeba coli. Intestinal protozoa infections might be of substantial health relevance even in settings where they are not considered as a health problem. Examination of a single stool sample with the ether-concentration method lacks sensitivity for the diagnosis of intestinal protozoa, and hence, care is indicated when interpreting prevalence estimates and treatment effects.

    Full Text Available Abstract This study explores underlying latent construct/s of gambling behaviour, and identifies indicators of “unhealthy gambling”. Data were collected from Youth’07 a nationally representative sample of New Zealand secondary school students (N = 9107. Exploratory factor analyses, item-response theory analyses, multiple indicators-multiple causes, and differential item functioning analyses were used to assess dimensionality of gambling behaviour, underlying factors, and indicators of unhealthy gambling. A single underlying continuum of gambling behaviour was identified. Gambling frequency and ‘gambling because I can’t stop’ were most strongly associated with unhealthy gambling. Gambling to ‘feel better about myself’ and to ‘forget about things’ provided the most precise discriminants of unhealthy gambling. Multivariable analyses found that school connectedness was associated with lower levels of unhealthy gambling.

    2016-12-01

    The aim of the study is to discuss and problematise notions of femininity and masculinity constructed in teaching situations among 16-year-old upper-secondary students studying science. The empirical examples originate from a teaching session with the theme of `sex and relationships'. The analysis is focused on metaphors inherent in a lesson that has its origins in the animal world. The findings show that the lesson `sex in the animal world' is full of anthropomorphism, metaphors that humanise animal behaviour. Teachers and students compare the animals' sexual behaviour with human behaviour, with the result that the animal world can be perceived as representative of natural sexual behaviour. The survey illustrates problems with how the examples are permeated by cultural values in the presentation of the animal world and how these examples form constructions of femininity and masculinity in the classroom.

    Full Text Available Sex, though not everything in life, is a profoundly important aspect of human existence. It has evolved to serve more than reproductive functions; relational and recreational functions having taken precedence over procrea­tional. Sex has come to play a much wider socio-psychological function.Human sexuality is complex and multidimensional. It is subject to influence by multitude of factors often grouped as biological (e.g. genes, hormones, psychological (e.g. fear, anxiety, mood and socio-cultural (e.g. sex roles, values- religious/moral/ethical, customs. It is the interaction and interrelationship of these factors from the time of conception, through intrauterine life, infancy, childhood and adolescence, till adulthood (even later in life that determine the sexual development expressed as sexual attitudes and behaviour of the people. Learning, both social and cognitive, plays a significantly important role in such development.Sexual dysfunctions in men and women, result from factors often categorised as physical or organic and psychological; more often a combination may be involved. Experience has shown that in majority of men and women in India having sexual problems, ignorance misconceptions and prevailing myths are invariably responsible in the causation of Ihese problems. Sexual problems in individual man (e.g. erectile failure and woman (e.g. vaginismus cause anxiety, feelings of frustration, lowered self esteem and symptoms of depression. The condition may also affect the spouse; he/she, as a reaction to the problem in the partner, may develop sexual and psychosocial problems including distressed marital relationship. This may also have influence on general couple relationship, effecting adversely the quality of family life.Modern therapeutic endevours have made it possible now to offer effective therapy to most people who seek help for their sexual problems, thus preventing the consequences on couple relationship. However, there is also

    We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities.

    The Colombian Ministry of Education has included in its secondary school programs 2 courses of sex education. The first course explores such subjects as prenatal and natal period, lactation, preschool children, behavior inside the family and in school. The 2nd. course is specifically directed to adolescents, investigating physical and emotional changes, eroticism, social pressure, and human relations. Moreover Colombia has had since 1955 special courses of 4-11 hours in sex education directed to young people engaged to be married, courses which have become obligatory in 1965 for those who desire a Catholic wedding. This article presents the findings and impressions of a sex education teacher who gave courses to adolescents of both sexes in a junior high school, and also premarital courses for a period of over 8 years. The author stresses the importance of such courses from an educational and a psychological point of view.

  2. The sex and sex determination in Pyropia haitanensis (Bangiales, Rhodophyta).

    Pyropia haitanensis has a biphasic life cycle with macroscopic gametophytic blade (n) and microscopic filamentous conchocelis (2n) phase. Its gametophytic blades have long been believed to be mainly dioecious. However, when crossing the red mutant (R, ♀) with the wild type (W, ♂), the parental colors were segregated in F1 blades, of which 96.1% were linearly sectored with 2-4 color sectors. When color sectors were excised from the color-sectored blades and cultured singly, 99.7% of the color sectors appeared to be unisexual with an equal sex ratio. Although the sex of color sector did not genetically link with its color, the boundaries of both sex and color sectors coincided precisely. About 87.9% of the examined color-sectored blades were monoecious and the percentage increased with the number of color sectors of a blade. The gametophytic blades from each conchocelis strain produced by parthenogenesis of the excised color sectors were unisexual and unicolor, showing the same sex and color as their original sectors. These results indicate that most of the sexually reproduced Py. haitanensis blades are monoecious, and their sex is controlled by segregation of a pair of alleles during meiosis of conchospore, forming a sex-sectored tetrad. During the subsequent development of blades, one or two lower cell(s) of the tetrad contribute mainly to rhizoid formation, and rarely show their sexual phenotype, leading to reduced frequency of full sex phenotype of the meiotic blades. Moreover, the aberrant segregations of sex genes or color genes in a few of F1 blades were probably due to gene conversions, but there was no sex transfer in Py. haitanensis.

  12. [In Nigeria: sexual permissiveness and sex education].

    Science.gov (United States)

    Demehin, A O

    1983-07-01

    Considering the population explosion in Nigeria which is due both to medical advances and traditional beliefs in large families as well as the recent trend of sexual permissiveness which involves the teenagers population, the author of the article considers that sex education is imperative in Nigeria. However, he sees many obstacles standing in the way of general acceptance of sex education. The husband-wife relationship does not encourage free communication on the subject and colonization has removed the traditional forms of sex education through initiation rites and pre-marital counseling by the elders so that young people nowadays rely mostly on peer information or erotic movies and publications. It seems to the author that the only avenue left open is to teach sex education through the school systems. A systematic review of the provisions for sex education in primary and secondary schools as well as teacher's training colleges bring the author to the conclusion that although the sex education curriculum seems comprehensive on paper, they are mere copies of similar American or Canadian programmes with very little attempt at indigenizing them. Furthermore, the syllabus seem to be concentrated on one year instead of being spread out over the school career. The author expresses his conviction that the topic could easily be made acceptable with the right approach and he advocates grounding sex education teaching in the traditional roots of the students.

During these clinical rotations, students are expected to acquire and master the basic procedural skills. However, students’ learning process should be evaluated for quality improvement. Objectives: This study was conducted to identify the basic medical procedural skills that third-year medical students should acquire and master and determine the level of students’ exposure on these procedures at the end of junior rotation in internal medicine. Identification of the gap between clinicians’ opinions, skills practiced by students, and third-year students’ curriculum in the medical department at CUHAS was also done. Methods: The descriptive cross-sectional study was used to collect data through a self-administered, structured questionnaire from clinicians in medicine. A review of logbooks was considered to determine level of students’ exposure, and a document analysis was done using existing medical curriculum. Results: The response of 71% (n=22 was obtained. Clinicians agreed on basic procedures that students should perform independently (ie, Foley catheter insertion, venipuncture, and intravenous drip insertion. Clinicians thought

  15. Sex education vital for Chinese adolescents.

    Zhang, Z

    1997-02-01

    This article summarizes findings from a survey conducted among adolescents in Beijing and Tianjin, China. Findings indicate that 89.3% of sex offenders were adolescents. Many high school students were engaged in premarital sexual relations, but lacked knowledge about sex and contraception. Premarital sex and sexually transmitted diseases are considered a social evil. The central government has direct jurisdiction in Tianjin and its population of 9 million. By 1989 there were 540,000, or 12% of total population, aged 12-16 years. A survey of 3231 junior middle school students aged 11-14 years revealed that 35% of girls did not know why menstruation occurred at a certain age. About 55% of boys did not know about erections. 35% considered an erect penis a part of normal physical development, but over 50% were confused. 30-50% of students who had reached menarche and sexual maturity found it difficult to find knowledgeable people. 50% received information from the mass media. 44% of girls learned from their mothers. 25% of boys and girls aged 11-12 years already had girlfriends and boyfriends. About 30% desired friends of the opposite sex and desired intimacy, love, and dependability among friends. It is argued that the backward notions of sex originated in a once feudal society that considered sex a taboo. Parents, teachers, and school authorities are resistant to introducing sex education; teachers are embarrassed by the subject matter. In Beijing about 4000 students aged 11-14 years were interviewed. These students had limited information on sex-related issues and misconceptions. Attitudes must be changed and teachers must be trained before adolescent health and sex education can be introduced into schools. The government can play a role in promoting programs for adolescents and coordinating the efforts of nongovernmental groups.

The AVF and DF structured test scores increased linearly as a function of age, whilst the relation between age and the DF unstructured test score was curvilinear (i.e., the improvement in test scores was much more pronounced for younger children than for older children). A higher mean level of parental education was associated with significantly higher AVF and DF structured test scores. Sex was not associated with any of the outcomes. Demographically corrected norms for the AVF and DF tests were established, and an automatic scoring program was provided.

    We recently described the effect of a single-dose antihelminthic treatment on vaccine immunogenicity to a seasonal influenza vaccine. Here we report the effect of antihelminthics on the immunogenicity of a meningococcal vaccine and a cholera vaccine in primary school children living in Lambaréné, Gabon. Since infection with helminths remains a major public health problem and the influence on cognitive and physical development as well as the immunomodulatory effects are well established, we investigated if a single-dose antihelminthic treatment prior to immunization positively influences antibody titers and vaccine-specific memory B-cells. In this placebo-controlled, double-blind trial the effect of a single-dose antihelminthic treatment prior to immunization with a meningococcal as well as with a cholera vaccine was investigated. Anti-meningococcal antibodies were assessed by serum bactericidal assay, cholera vaccine-specific antibody titers by Enzyme-linked Immunosorbent Assay (ELISA) at baseline (Day 0; vaccination), four weeks (Day 28) and 12weeks (Day 84) following vaccination. Meningococcal and cholera vaccine-specific memory B-cells were measured at Day 0 and 84 by vaccine-specific Enzyme-linked Immunospot (ELISpot) assay. The helminth burden of the participants was assessed four weeks before vaccination (Day -28) and at Day 84 by the Merthiolate-Iodine-Formaldehyde technique. Out of 280 screened school children, 96 received a meningococcal vaccine and 89 a cholera vaccine following allocation to either the single-dose antihelminthic treatment group or the placebo group. Bactericidal antibody titers increased following immunization with the meningococcal vaccine at Day 28 and Day 84 in 68 participants for serogroup A, and in 80 participants for serogroup C. The cholera vaccine titers increased in all participants with a peak at Day 28. The number of memory B-cells increased following vaccination compared to baseline. There was no statistically significant

    Full Text Available Video modeling is one of the recognized methods used in the training and teaching of children with Autism Spectrum Disorders (ASD. The model’s theoretical base stems from Albert Bandura's (1977; 1986 social learning theory in which he asserts that children can learn many skills and behaviors observationally through modeling. One can assume that by observing others, a child with ASD can construct an idea of how new behaviors are performed, and on later occasions this mentally and visually constructed information will serve as a guide for his/her way of behaving. There are two types of methods for model learning: 1 In Vivo Modeling and 2 Video Modeling. These can be used a to teach children with ASD skills that are not yet in their behavioral repertoire and / or b to improve the children's emerging behaviors or skills. In the case of linguistic minority children at any stage of their bilingual development, it has been presumed that some of their behaviors that can be interpreted as attitude or culture-related actions. This approach, however, can sometimes delay referral, diagnosis, and intervention. In our project, we used Video Modeling and positive targeted results with regard to teaching social communication skills and target behavior to an eleven year-old bilingual boy with ASD. Our study also reveals that through Video Modeling, children with ASD can learn desirable behavioral skills as by-products. Video Modeling can also contribute positively to the social inclusion of bilingual children with ASD in school settings. In other words, bilingual children with ASD can transfer the social communication skills and targeted behaviors they learn through second-language at school to a first-language milieu.

    Full program implementation is crucial for effectiveness but is often overlooked or insufficiently considered during development of behavioral change interventions. For school-based health promotion programs, teachers are key players in program implementation, but teacher support in this phase is mostly limited to technical support and information. To ensure optimal implementation of the Dutch school-based sexual health program Long Live Love, a Web-based coaching website was developed to support teachers in completeness and fidelity of program implementation. The aim of this paper is to provide insight into the process of systematic development of a Web-based coaching intervention to support teachers in their implementation of a school-based sexual health program. The intervention mapping (IM) protocol was applied for the development of a theory- and evidence-based intervention. The IM process begins with (1) a needs assessment, followed by (2) the formulation of change objectives, (3) the selection of theory-based intervention methods and practical applications that take the parameters for effectiveness into consideration, (4) integration of practical applications into an organized program, (5) planning for adoption, implementation, and sustainability of the program, and finally, (6) generating an evaluation plan to measure program effectiveness. Teacher's implementation behavior was characterized by inconsistently selecting parts of the program and not delivering (all) lessons as intended by program developers. Teachers, however, did not perceive this behavior as problematic, revealing the discrepancy between teacher's actual and perceived need for support in delivering Long Live Love lessons with completeness and fidelity. Teachers did, however, acknowledge different difficulties they encountered which could potentially negatively influence the quality of implementation. With the IM protocol, this Web-based coaching intervention was developed based on a concept

    To compare initial and recurrent concussions regarding average number of days between concussions, acute concussion symptoms and symptom resolution time, and return to play time. High school athletes sustaining multiple concussions linked within sport seasons drawn from a large sports injury surveillance study. Retrospective analysis of longitudinal surveillance data. Number of days between concussions, number of symptoms endorsed, specific symptoms endorsed, symptom resolution time, return to play time. Median time between initial and recurrent concussions was 21 days (interquartile range = 10-43 days). Loss of consciousness, the only significant symptom difference, occurred more frequently in recurrent (6.8%) than initial (1.7%) concussions (P = .04). No significant difference was found in the number of symptoms (P = .84) or symptom resolution time (P = .74). Recurrent concussions kept athletes from play longer than initial concussions (P concussions were season ending. We found that athletes' initial and recurrent concussions had similar symptom presentations and resolution time. Despite these similarities, athletes were restricted from returning to play for longer periods following a recurrent concussion, indicating clinicians are managing recurrent concussions more conservatively. It is probable that concussion recognition and management are superior now compared with when previous studies were published, possibly improving recurrent concussion outcomes.

  7. Sex-chromosome anaphase movements in crane-fly spermatocytes are coordinated: ultraviolet microbeam irradiation of one kinetochore of one sex chromosome blocks the movements of both sex chromosomes

    Swedak, J.A.M.; Forer, A.

    1987-01-01

    Sex chromosomes in crane-fly spermatocytes move polewards at anaphase after the autosomes have reached the poles. We irradiated one kinetochore of one sex chromosome using an ultraviolet microbeam. When both sex chromosomes were normally oriented, irradiation of a single kinetochore permanently blocked movement of both sex chromosomes. Irradiation of non-kinetochore chromosomal regions or of spindle fibres did not block movement, or blocked movement only temporarily. We argue that ultraviolet irradiation of one kinetochore blocks movement of both sex chromosomes because of effects on a 'signal' system. Irradiation of one kinetochore of a maloriented sex chromosome did not block motion of either sex chromosome. However, irradiation of one kinetochore of a normally oriented sex chromosome permanently blocked motion of both that sex chromosome and the maloriented sex chromosome. Thus for the signal system to allow the sex chromosomes to move to the pole each sex chromosome must have one spindle fibre to each pole. (author)

    Sex determination can be robustly genetic, strongly environmental, or genetic subject to environmental perturbation. The genetic basis of sex determination is unknown for zebrafish (Danio rerio), a model for development and human health. We used RAD-tag population genomics to identify sex-linked polymorphisms. After verifying this “RAD-sex” method on medaka (Oryzias latipes), we studied two domesticated zebrafish strains (AB and TU), two natural laboratory strains (WIK and EKW), and two recent isolates from nature (NA and CB). All four natural strains had a single sex-linked region at the right tip of chromosome 4, enabling sex genotyping by PCR. Genotypes for the single nucleotide polymorphism (SNP) with the strongest statistical association to sex suggested that wild zebrafish have WZ/ZZ sex chromosomes. In natural strains, “male genotypes” became males and some “female genotypes” also became males, suggesting that the environment or genetic background can cause female-to-male sex reversal. Surprisingly, TU and AB lacked detectable sex-linked loci. Phylogenomics rooted on D. nigrofasciatus verified that all strains are monophyletic. Because AB and TU branched as a monophyletic clade, we could not rule out shared loss of the wild sex locus in a common ancestor despite their independent domestication. Mitochondrial DNA sequences showed that investigated strains represent only one of the three identified zebrafish haplogroups. Results suggest that zebrafish in nature possess a WZ/ZZ sex-determination mechanism with a major determinant lying near the right telomere of chromosome 4 that was modified during domestication. Strains providing the zebrafish reference genome lack key components of the natural sex-determination system but may have evolved variant sex-determining mechanisms during two decades in laboratory culture.

  9. Chromosome chains and platypus sex: kinky connections.

    Science.gov (United States)

    Ashley, Terry

    2005-07-01

    Mammal sex determination depends on an XY chromosome system, a gene for testis development and a means of activating the X chromosome. The duckbill platypus challenges these dogmas.(1,2) Gutzner et al.(1) find no recognizable SRY sequence and question whether the mammalian X was even the original sex chromosome in the platypus. Instead they suggest that the original platypus sex chromosomes were derived from the ZW chromosome system of birds and reptiles. Unraveling the puzzles of sex determination and dosage compensation in the platypus has been complicated by the fact that it has a surplus of sex chromosomes. Rather than a single X and Y chromosome, the male platypus has five Xs and five Ys. Copyright (c) 2005 Wiley Periodicals, Inc.

    This study evaluated a 90-min single session school-based body image intervention (Dove Confident Me: Single Session), and investigated if delivery could be task-shifted to teachers. British adolescents (N = 1707; 11-13 years; 50.83% girls) participated in a cluster randomised controlled trial [lessons as usual control; intervention teacher-led (TL); intervention researcher-led (RL)]. Body image, risk factors, and psychosocial and disordered eating outcomes were assessed 1-week pre-intervention, immediate post-intervention, and 4-9.5 weeks follow-up. Multilevel mixed-models showed post-intervention improvements for intervention students relative to control in body esteem (TL; girls only), negative affect (TL), dietary restraint (TL; girls only), eating disorder symptoms (TL), and life engagement (TL; RL). Awareness of sociocultural pressures increased at post-intervention (TL). Effects were small-medium in size (ds 0.19-0.76) and were not maintained at follow-up. There were no significant differences between conditions at post or follow-up on body satisfaction, appearance comparisons, teasing, appearance conversations and self-esteem. The intervention had short-term benefits for girls' body image and dietary restraint, and for eating disorder symptoms and some psychosocial outcomes among girls and boys. A multi-session version of the intervention is likely to be necessary for sustained improvements. Teachers can deliver this intervention effectively with minimal training, indicating broader scale dissemination is feasible. ISRCTN16782819. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    Sex chromosome drivers are selfish elements that subvert Mendel's first law of segregation and therefore are overrepresented among the products of meiosis. The sex-biased progeny produced then fuels an extended genetic conflict between the driver and the rest of the genome. Many examples of sex chromosome drive are known, but the occurrence of this phenomenon is probably largely underestimated because of the difficulty to detect it. Remarkably, nearly all sex chromosome drivers are found in t...

  11. Sex Reversal in Birds.

    Science.gov (United States)

    Major, Andrew T; Smith, Craig A

    2016-01-01

    Sexual differentiation in birds is controlled genetically as in mammals, although the sex chromosomes are different. Males have a ZZ sex chromosome constitution, while females are ZW. Gene(s) on the sex chromosomes must initiate gonadal sex differentiation during embryonic life, inducing paired testes in ZZ individuals and unilateral ovaries in ZW individuals. The traditional view of avian sexual differentiation aligns with that expounded for other vertebrates; upon sexual differentiation, the gonads secrete sex steroid hormones that masculinise or feminise the rest of the body. However, recent studies on naturally occurring or experimentally induced avian sex reversal suggest a significant role for direct genetic factors, in addition to sex hormones, in regulating sexual differentiation of the soma in birds. This review will provide an overview of sex determination in birds and both naturally and experimentally induced sex reversal, with emphasis on the key role of oestrogen. We then consider how recent studies on sex reversal and gynandromorphic birds (half male:half female) are shaping our understanding of sexual differentiation in avians and in vertebrates more broadly. Current evidence shows that sexual differentiation in birds is a mix of direct genetic and hormonal mechanisms. Perturbation of either of these components may lead to sex reversal. © 2016 S.

    Sex is a mysterious phenomenon, which has puzzled even great sages. Human beings have researched and mastered the biology of sex. But that is not all. Sex needs to be understood from the spiritual perspective too. The vision of Osho is an enlightening experience in this regard. Out of the thousands of lectures, five lectures on sex made Osho most notorious. Born into a Jain family of Madhya Pradesh, Rajneesh, who later wanted himself to be called Osho, is a great master. He has spoken volumes on a wide range of topics ranging from sex to super-consciousness. His contributions in the area of sex are based on the principles of "Tantra" which has its origin from Buddhism. This article focuses on his life and insights on sex, which if understood properly, can be a stepping stone for enlightenment.

    Ileena Mitra

    2016-11-01

    Full Text Available Sexual dimorphism in common disease is pervasive, including a dramatic male preponderance in autism spectrum disorders (ASDs. Potential genetic explanations include a liability threshold model requiring increased polymorphism risk in females, sex-limited X-chromosome contribution, gene-environment interaction driven by differences in hormonal milieu, risk influenced by genes sex-differentially expressed in early brain development, or contribution from general mechanisms of sexual dimorphism shared with secondary sex characteristics. Utilizing a large single nucleotide polymorphism (SNP dataset, we identify distinct sex-specific genome-wide significant loci. We investigate genetic hypotheses and find no evidence for increased genetic risk load in females, but evidence for sex heterogeneity on the X chromosome, and contribution of sex-heterogeneous SNPs for anthropometric traits to ASD risk. Thus, our results support pleiotropy between secondary sex characteristic determination and ASDs, providing a biological basis for sex differences in ASDs and implicating non brain-limited mechanisms.

    2016-01-01

    As society continues to advocate an unrealistically thin body shape, awareness and internalization of appearance and its consequent impact upon self-esteem has become increasingly of concern, particularly in adolescent girls. School gender environment may influence these factors, but remains largely unexplored. This study aimed to assess differences between two different school environments in appearance attitudes, social influences and associations with self-esteem. Two hundred and twelve girls (M = 13.8 years) attending either a single-sex or co-educational school completed measures on socio-cultural attitudes towards appearance, social support and self-esteem. Though marginal differences between school environments were found, significantly higher internalization was reported among girls at the co-educational school. School environment moderated relations between internalization and self-esteem such that girls in co-educational environments had poorer self-esteem stemming from greater internalization. Thus, in a single-sex school environment, protective factors may attenuate negative associations between socio-cultural attitudes towards appearance and self-esteem in adolescent girls.

Design: This was a retrospective analysis of a large repository of anonymous test results and pretest risk factors for OSA. Setting and patients: A total of 272,705 patients were referred for home sleep apnea testing from a variety of clinical practices for suspected sleep disordered breathing across North America from 2009 to 2013. Interventions: Not applicable. Measurements and results: Predictors of OSA (apnea hypopnea index4%≥5 were evaluated by multiple logistic regression; sex differences were evaluated by interaction effects. Middle age was the single most robust predictor of OSA for both sexes and was particularly foretelling for females (P<0.001 even after controlling for measures of adiposity and medical conditions. Females over the age of 45 years were much more likely to have OSA compared to their younger counterparts (78.7% vs 42.5%, respectively; odds ratio: 5.0 versus males (88.1% vs 68.8%, respectively; odds ratio: 3.4. Snoring, although more frequently reported by males, was similarly predictive of OSA for both sexes. Witnessed apneas and measures of adiposity were better predictors of OSA for males than females. Insomnia, depression, and use of sleep medication, although more commonly reported in females, did not predict OSA. Hypertension, although equally reported by both sexes, performed better as a predictor in females (P<0.001, even after controlling for age, measures of adiposity, and other medical conditions. Diabetes, heart disease, stroke, and sleepiness did not contribute unique variance in OSA in adjusted models. Conclusion: This study

    Full Text Available Historically, academic literature on sex work has documented the changing debates, policies, and cultural discourse surrounding the sex industry, and their impact on the rights of sex workers worldwide. As sex work scholars look to the future of sex workers’ rights, however, we are also in a critical moment of self-reflection on how sex work scholarship engages with sex worker communities, produces knowledge surrounding sex work, and represents the lived experiences of sex workers’ rights, organizing, and activism. In this short Communication, proceedings from a recent sex work research symposium entitled, Sexual Economies, Politics, and Positionality in Sex Work Research are presented. Held at the Centre for Refugee Studies at York University, this symposium is a response to the need for sex work researchers, sex workers, and sex worker-led organizations to come together and critically examine the future of research on sex work and the politics of documenting sex workers’ rights.

    Objectives Sex and relationship education (SRE) is regarded as vital to improving young people’s sexual health, but a third of schools in England lacks good SRE and government guidance is outdated. We aimed to identify what makes SRE programmes effective, acceptable, sustainable and capable of faithful implementation. Design This is a synthesis of findings from five research packages that we conducted (practitioner interviews, case study investigation, National Survey of Sexual Attitudes and Lifestyles, review of reviews and qualitative synthesis). We also gained feedback on our research from stakeholder consultations. Settings Primary research and stakeholder consultations were conducted in the UK. Secondary research draws on studies worldwide. Results Our findings indicate that school-based SRE and school-linked sexual health services can be effective at improving sexual health. We found professional consensus that good programmes start in primary school. Professionals and young people agreed that good programmes are age-appropriate, interactive and take place in a safe environment. Some young women reported preferring single-sex classes, but young men appeared to want mixed classes. Young people and professionals agreed that SRE should take a ‘life skills’ approach and not focus on abstinence. Young people advocated a ‘sex-positive’ approach but reported this was lacking. Young people and professionals agreed that SRE should discuss risks, but young people indicated that approaches to risk need revising. Professionals felt teachers should be involved in SRE delivery, but many young people reported disliking having their teachers deliver SRE and we found that key messages could become lost when interpreted by teachers. The divergence between young people and professionals was echoed by stakeholders. We developed criteria for best practice based on the evidence. Conclusions We identified key features of effective and acceptable SRE. Our best practice

    This study aimed to identify the views of young people, parents and teachers concerning sex education in Lesotho. It was conducted at a time when the national government was considering the introduction of Population and Family Life Education, which includes sex education, into the national school curriculum. Forty-six focus group discussions were held with young people (10), parents (30) and teachers (6) to identify current sources of sex education and views of the proposed introduction of school-based sex education in Lesotho. Findings show the limited and problematic sources of sex education for adolescents in Lesotho. They also highlight broad support for the introduction of sex education in the national school curriculum among young people, parents and teachers. Of key importance for the development of a sex education curriculum is the balance between providing young people with information and developing their skills in sexual empowerment and negotiating sexual pressure. The use of pupil-centred interactive pedagogies was seen as essential. Teachers, however, highlighted the need for training in the delivery of sex education, which includes instruction on course materials, teaching methodologies and developing sensitivity to teaching sexual issues to young people.

    Sex differences in the prevalence of affective disorders might be attributable to different sex hormone milieu. The effects of short-term sex hormone deficiency on behavior, especially on anxiety have been studied in numerous animal experiments, mainly on young adult rats and mice. However, sex differences in aged animals and the effects of long-term hypogonadism are understudied. The aim of our study was to analyze sex differences in anxiety-like behavior in aged rats and to prove whether they can be attributed to endogenous sex hormone production in males. A battery of tests was performed to assess anxiety-like behavior in aged female, male and gonadectomized male rats castrated before puberty. In addition, the aged gonadectomized male rats were treated with a single injection of estradiol or testosterone or supplemented with estradiol for two-weeks. Female rats displayed a less anxious behavior than male rats in most of the conducted behavioral tests except the light-dark box. Long-term androgen deficiency decreased the sex difference in anxiety either partially (open field, PhenoTyper cage) or completely (elevated plus maze). Neither single injection of sex hormones, nor two-week supplementation of estradiol in gonadectomized aged male rats significantly affected their anxiety-like behavior in the elevated plus maze. In conclusion, our results confirm sex differences in anxiety in aged rats likely mediated by endogenous testosterone production in males. Whether long-term supplementation with exogenous sex hormones could affect anxiety-like behavior in elderly individuals remains to be elucidated. Copyright © 2017 Elsevier Inc. All rights reserved.

    Johnson, Sonya L.

    The purpose of this study was to determine how and to what extent single gender science classes affect motivation to learn scientific concepts, interest in science, and college major intent among high school and middle school girls. This study was designed to determine whether students' motivation to learn science changes when they are placed in a single gender science class. The study also measured whether the students' level of interest in science and desire to major in science changes based on their enrollment in a single gender class. Finally, the study investigated the career and college major intentions of the sample population used in the study. Girls in single gender groupings engage in more academic risk taking and participate more than girls in coeducational classes. This benefit alone responds to reform efforts and supports the abolition of gender-based obstacles. Single gender grouping could help encourage more girls to take interest in majoring in science, a field that is considered to be masculine. By increasing students' interest in science while enrolled in single gender classes, students may become more motivated to learn science. This study was conducted using seven, eighth, ninth and tenth grade girls from single sex and coeducational science classes. The students participated in 2 surveys, the Science Motivational Survey and the Test of Science Related Attitudes, at the beginning of the semester and at the end of the semester. In respect to girls in high school single gender science classes, results were contrary to recent studies that state that girls who received science education in a single gender setting have an increase in motivation and attitude towards science. The results did show that middle school girls in single gender science classes did show an increase in motivation.

  14. Sexting by High School Students.

    2017-08-01

    In the last 8 years, several studies have documented that many adolescents acknowledge having exchanged sexually explicit cell phone pictures of themselves, a behavior termed sexting. Differences across studies in how sexting was defined, recruitment strategies, and cohort have resulted in sometimes significant differences in as basic a metric as what percentage of adolescents have sent, received, or forwarded such sexts. The psychosocial and even legal risks associated with sexting by minors are significantly serious that accurate estimates of its prevalence, including over time, are important to ascertain. In the present study, students (N = 656) from a single private high school were surveyed regarding their participation in sexting. Students at this same school were similarly surveyed four years earlier. In this second survey, reported rates of sending (males 15.8%; females 13.6%) and receiving (males 40.5%; females 30.6%) sexually explicit cell phone pictures (revealing genitals or buttocks of either sex or female breasts) were generally similar to those reported at the same school 4 years earlier. Rates of forwarding sexts (males 12.2%; females 7.6%) were much lower than those previously acknowledged at this school. Correlates of sexting in this study were similar to those reported previously. Overall, our findings suggest that sexting by adolescents (with the exception of forwarding) remains a fairly common behavior, despite its risks.

    Human sexuality is a complex part of life and is considered a multidimensional phenomenon. Therefore there is an increased need for adequate and comprehensive sex education, especially for teenagers and young adults. The main aim of the study was to evaluate the level of students' sexual knowledge, as well as to identify their sources of information regarding sexual life and reproduction. A cross-sectional study using a designed self-report questionnaire was performed. The study population consisted of 936 students who were attending 10 high schools and four medical schools in Attica. Data were collected after obtaining permission from the Pedagogic Institute of the Greek Ministry of Education. The main sources of students' sexual information about reproduction were friends (29.1%) and parents (24.0%), whereas school was reported by 14.3% of them. The preferred sources of information, according to students' perceptions, were sex education specialists (65.6%), followed by school (39.1%), parents (32.2%) and friends (27.7%). The importance of school, peer and parent support upon adolescents' sexual life was revealed by the results of the study. Students' knowledge level on sex topics is not satisfactory and therefore there is a need for sex education specialists and special courses regarding sex education in Greek schools.

    To evaluate foreign language acquisition at school in cochlear implant patients. Cohort study. CI center. Forty three cochlear implants (CI) patients (10-18 yr) were evaluated. CI nonusers and patients with CI-explantation, incomplete datasets, mental retardation, or concomitant medical disorders were excluded. Additional data (type of schooling, foreign language learning, and bilingualism) were obtained with questionnaires. German-speaking children with foreign tuition language (English and/or French) at school were enrolled for further testing. General patient data, auditory data, and foreign language data from both questionnaires and tests were collected and analyzed. Thirty seven out of 43 questionnaires (86%) were completed. Sixteen (43%) were in mainstream education. Twenty-seven CI users (73%) have foreign language learning at school. Fifteen of these were in mainstream education (55%), others in special schooling. From 10 CI users without foreign language learning, one CI user was in mainstream education (10%) and nine patients (90%) were in special schooling. Eleven German-speaking CI users were further tested in English and six additionally in French. For reading skills, the school objectives for English were reached in 7 of 11 pupils (64%) and for French in 3 of 6 pupils (50%). For listening skills, 3 of 11 pupils (27%) reached the school norm in English and none in French. Almost 75% of our CI users learn foreign language(s) at school. A small majority of the tested CI users reached the current school norm for in English and French in reading skills, whereas for hearing skills most of them were not able to reach the norm.

    The objective of this study was to assess the factors associated with methamphetamine (MA) use, syphilis, and unprotected sex among female sex workers from different type of venues in Qingdao City, Shandong Province of China. Three consecutive cross-sectional surveys provided information on demographics, sexual and drug use behaviors, and HIV-related services. Of 1187 participants, 3.0% were infected with syphilis; 30.2% ever used MA; 58.3% ever had unprotected commercial sex in the past month. The prevalence rates of syphilis and MA use were 2.5% and 33.0% for participants recruited from saunas, night clubs, bars or hotels; 2.7% and 28.3% for hair/beauty salon-based participants; and 4.5% and 15.8% for street-based participants. Street-based MA users were more likely to be single, non-Shandong residents, have first lifetime sex act at younger age, and recruited in 2008 (vs. 2006). Saunas, night clubs, bars, or hotels-based MA users were more likely to be younger, sex debut at younger age, have longer duration of sex work, have unprotected commercial sex, and be syphilis-infected. Hair/beauty salon-based MA users were more likely to be non-Shandong residents, younger, and to have unprotected commercial sex. Syphilis among the sauna-, night club-, bar-, or hotel-based participants was associated with MA use and ever receipt of HIV testing. Syphilis among the hair/beauty salon-based participants was associated with longer duration of sex work. MA users who frequent commercial sex venues are engaging in high-risk behaviors and are at risk for syphilis/other sexually transmitted diseases. Better-targeted intervention efforts to curtail the epidemics of MA use and HIV/syphilis should therefore take cognizance of the role of commercial sex venues as focal points of MA use and syphilis/sexually transmitted disease transmission.

    Steroid sex hormones and SHBG may modify metabolism and diabetes risk, with implications for sex-specific diabetes risk and effects of prevention interventions. This study aimed to evaluate the relationships of steroid sex hormones, SHBG and SHBG single-nucleotide polymorphisms (SNPs) with diabetes risk factors and with progression to diabetes in the Diabetes Prevention Program (DPP). This was a secondary analysis of a multicenter randomized clinical trial involving 27 U.S. academic institutions. The study included 2898 DPP participants: 969 men, 948 premenopausal women not taking exogenous sex hormones, 550 postmenopausal women not taking exogenous sex hormones, and 431 postmenopausal women taking exogenous sex hormones. Participants were randomized to receive intensive lifestyle intervention, metformin, or placebo. Associations of steroid sex hormones, SHBG, and SHBG SNPs with glycemia and diabetes risk factors, and with incident diabetes over median 3.0 years (maximum, 5.0 y). T and DHT were inversely associated with fasting glucose in men, and estrone sulfate was directly associated with 2-hour post-challenge glucose in men and premenopausal women. SHBG was associated with fasting glucose in premenopausal women not taking exogenous sex hormones, and in postmenopausal women taking exogenous sex hormones, but not in the other groups. Diabetes incidence was directly associated with estrone and estradiol and inversely with T in men; the association with T was lost after adjustment for waist circumference. Sex steroids were not associated with diabetes outcomes in women. SHBG and SHBG SNPs did not predict incident diabetes in the DPP population. Estrogens and T predicted diabetes risk in men but not in women. SHBG and its polymorphisms did not predict risk in men or women. Diabetes risk is more potently determined by obesity and glycemia than by sex hormones.

    Children and adolescents with disabilities (CAD) frequently engage in inappropriate sexual behaviors. In Indonesia, the need for sex education for CAD remains unclear. This study investigated teacher attitudes toward providing sex education in special schools to clarify the gender differences among teachers providing sex education. Questionnaires were sent to 180 teachers. The response rate was 72.2%. Eighty-three percent of responders were Muslim. Our findings revealed that teachers in special schools considered sex education to be important. However, the number of sex education contents was limited, and female teachers were more positive about teaching sex education than male teachers. Equally, female teachers taught a greater number of sex education contents than did male teachers. These findings were consistent with reports from developed countries although cultural and religious background differed from those of Indonesia. Sex education for CAD was accepted by teachers in Indonesia; however, materials and tools for education should be developed further.

    Full Text Available Abstract Background Although men who have sex with men (MSM are disproportionately affected by HIV/AIDS in Mexico, data on current risk behaviors in this population are lacking. This study investigated the prevalence and correlates of unprotected anal intercourse (UAI in a sample of 260 MSM in Tijuana, Mexico. Methods In June 2010, men attending a gay pride celebration were invited to complete a sexual risk survey. Men who reported UAI with a male partner in the past year were compared with men who reported only protected anal sex during the same period. Results Mean age of participants was 29.7; 54% had a high school diploma or less; and 43% were unemployed. In the past year, 55% had been tested for HIV, 21% reported using illicit drugs before or during sex, and 94% had sex only with men. Overall, 50% reported having UAI with another male in the past year. Factors independently associated with UAI in the past year were unemployment (AOR = 1.87, attending adult movie theaters (AOR = 2.21, using illicit drugs before or during sex (AOR = 2.43, and not having a recent HIV test (AOR = 1.85. Conclusions Interventions to promote HIV testing and condom use among men who have sex with men may want to consider venue-specific approaches, as well as focus on drug-use issues in the context of unsafe sex.

  6. Multiple sex-associated regions and a putative sex chromosome in zebrafish revealed by RAD mapping and population genomics.

    Jennifer L Anderson

    Full Text Available Within vertebrates, major sex determining genes can differ among taxa and even within species. In zebrafish (Danio rerio, neither heteromorphic sex chromosomes nor single sex determination genes of large effect, like Sry in mammals, have yet been identified. Furthermore, environmental factors can influence zebrafish sex determination. Although progress has been made in understanding zebrafish gonad differentiation (e.g. the influence of germ cells on gonad fate, the primary genetic basis of zebrafish sex determination remains poorly understood. To identify genetic loci associated with sex, we analyzed F(2 offspring of reciprocal crosses between Oregon *AB and Nadia (NA wild-type zebrafish stocks. Genome-wide linkage analysis, using more than 5,000 sequence-based polymorphic restriction site associated (RAD-tag markers and population genomic analysis of more than 30,000 single nucleotide polymorphisms in our *ABxNA crosses revealed a sex-associated locus on the end of the long arm of chr-4 for both cross families, and an additional locus in the middle of chr-3 in one cross family. Additional sequencing showed that two SNPs in dmrt1 previously suggested to be functional candidates for sex determination in a cross of ABxIndia wild-type zebrafish, are not associated with sex in our AB fish. Our data show that sex determination in zebrafish is polygenic and that different genes may influence sex determination in different strains or that different genes become more important under different environmental conditions. The association of the end of chr-4 with sex is remarkable because, unique in the karyotype, this chromosome arm shares features with known sex chromosomes: it is highly heterochromatic, repetitive, late replicating, and has reduced recombination. Our results reveal that chr-4 has functional and structural properties expected of a sex chromosome.

    The concentration of yolk steroids was suggested to influence offspring gender in oviparous animals subject to both temperature-dependent sex determination (TSD) and genotypic sex determination (GSD). However, the proposed mechanisms of steroid effects are thought to differ between TSD and GSD: a direct effect of oestrogens on gonad feminisation in TSD species vs a differential induction of male-producing or female-producing gametes in GSD species. Geckos offer an ideal opportunity for testing these suggested mechanisms. Closely related gecko species differ in their modes of sex determination. They lay clutches of two synchronously formed eggs; both eggs share equal steroid levels. If identical hormonal composition and environment during vitellogenesis, gravidity and incubation determine the sex of the progeny, siblings should share the same gender in both TSD and GSD geckos. We found strong support for this prediction in a TSD gecko species. Among clutches that were incubated at the temperature that produced both sexes, there were no clutches with siblings of the opposite sex. On the other hand, about half of the clutches yielded siblings of the opposite sex in four GSD species. These results suggest that sex-determining systems constrain the ability of the female to produce single-sex siblings and, hence, it seems that the GSD mechanism constrains the opportunities for sex ratio manipulation in geckos via yolk steroid manipulation.

    Children are more sensitive to pollutants than adults and yet they spend large amounts of time in school environments where they are exposed to unknown levels of indoor pollutants. This study investigated the concentrations of the most abundant volatile organic compounds (VOCs) in eight naturally ventilated school buildings in Italy. The schools were chosen to include areas with different urbanization and traffic density characteristics in order to gather a more diverse picture of exposure risks in the different areas of the city. VOCs were sampled for one week in the presence/absence of pupils using diffusive samplers suitable for thermal desorption inside three classrooms at each school. The samples were then analyzed with thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). In addition, outdoor measurements were carried out in the yard at each school. VOC identification and quantification, and indoor/outdoor concentration plots were used to identify pollutant sources. While some classrooms were found to have very low VOC levels, others had a significant indoor contribution or a prevalent outdoor contribution. High concentrations of terpenes were found in all monitored classrooms: a-pinene and limonene were in the range of 6.55-34.18 µg/m3 and 11.11-25.42 µg/m3 respectively. Outdoor concentrations were lower than indoors for each monitored school. Indicators based on health risk assessment for chronic health effects associated with VOCs (either carcinogenic or non-carcinogenic) were proposed to rank sites according to their hazard level.

    How do teenagers located in the KwaZulu-Natal province of South Africa, the epicentre of the HIV pandemic, give meaning to sexuality? This paper examines teenage black Africans investments in sex and sexuality and the gendered dynamics through which sexuality is articulated. Whilst unequal gender relations of power continue to feature prominently within relationship dynamics fuelling the gendering of HIV, attention to the micro-processes through which relationships are forged remain significant in illustrating the complex connections between love, sex and gender. Drawing on empirical findings with teenagers between the ages of 16 and 17 years old, the paper shows how relationships are conceptualised based on discourses of love. Love is inextricably bound up with sex and when teenagers talk about love and sex they also talk about condom use, multiple sexual partners and gender inequalities. What teenagers were interested in for their sexual relationships was not raised in sex education programmes at school. Implications for addressing teenage constructions of sexuality are discussed in the conclusion.

    Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

    To investigate age and sex differences in factors associated with the onset of cannabis use among adolescents. A representative sample of schoolchildren from secondary schools in Barcelona (n=1056) was selected and followed-up from the first to the fourth year of secondary education (7-10th grades). The participants completed a self-administered lifestyle questionnaire each year. Multilevel logistic regression models were used for each year and sex to analyse predictors of cannabis use; the second level was adjusted by school. Onset of cannabis use during follow-up was associated with a prior history of tobacco smoking [odds ratio (OR)=7.7 in boys; OR=3.8 in girls], alcohol consumption (OR=6.4 in boys; OR=3.2 in girls), antisocial behavior (OR=2.8 in boys; OR=2.2 in girls), intention to use drugs (OR=3.5 in boys; OR=4.2 in girls), drug use among friends (OR=2.5 in boys; OR=3.7 in girls) and spending leisure time in bars or discos (OR=2.1 in boys; OR=3.8 in girls). Moreover, among girls, attending state schools (OR=2.9), low academic performance (OR=5.7) and living in a single-parent family (OR=2.0) also independently predicted cannabis use. This study reveals a wide array of predictive factors in cannabis use onset that largely differed by age and sex. The results support the role of tobacco and alcohol, as well as the influence of drug use among friends, and the importance of leisure time patterns as facilitators of cannabis use.

    Tourists traveling internationally lower their inhibitions and take greater risks than they would typically in their home cultures. Loneliness, boredom, and a sense of freedom contribute to this behavioral change. Some tourists travel internationally in search of sexual gratification. This motivation may be actively conscious or subconscious to the traveler. Billed as romantic with great natural beauty, Thailand, the Philippines, Brazil, the Dominican Republic, and Kenya are popular destinations of tourists seeking sex. The Netherlands and countries in eastern Europe are also popular. With most initial cases of HIV infection in Europe having histories of international travel, mass tourism is a major factor in the international transmission of AIDS. While abroad, tourists have sex with casual partners, sex workers, and/or other tourists. Far from all tourists, however, carry and consistently use condoms with these partners. One study found female and non white travelers to be less likely than Whites and males to carry condoms. The risk of HIV infection increases in circumstances where condoms are not readily available in the host country and/or are of poor quality. Regarding actual condom use, a study found only 34% of sex tourists from Switzerland to consistently use condoms while abroad. 28% of men in an STD clinic in Melbourne, Australia, reported consistent condom use in sexual relations while traveling in Asia; STDs were identified in 73% of men examined. The few studies of tourists suggest that a significant proportion engage in risky behavior while traveling. HIV prevalence is rapidly increasing in countries known as destinations for sex tourism. High infection rates are especially evident among teenage sex workers in Thailand. Simply documenting the prevalence of risky behavior among sex tourists will not suffice. More research is needed on travelers and AIDS with particular attention upon the motivating factors supporting persistent high-risk behavior.

      The fourth edition of the Preparticipation Physical Evaluation recommends functional testing for the musculoskeletal portion of the examination; however, normative data across sex and grade level are limited. Establishing normative data can provide clinicians reference points with which to compare their patients, potentially aiding in the development of future injury-risk assessments and injury-mitigation programs.   To establish normative functional performance and limb-symmetry data for high school-aged male and female athletes in the United States.   Cross-sectional study.   Athletic training facilities and gymnasiums across the United States.   A total of 3951 male and female athletes who participated on high school-sponsored basketball, football, lacrosse, or soccer teams enrolled in this nationwide study.   Functional performance testing consisted of 3 evaluations. Ankle-joint range of motion, balance, and lower extremity muscular power and landing control were assessed via the weight-bearing ankle-dorsiflexion-lunge, single-legged anterior-reach, and anterior single-legged hop-for-distance (SLHOP) tests, respectively. We used 2-way analyses of variance and χ 2 analyses to examine the effects of sex and grade level on ankle-dorsiflexion-lunge, single-legged anterior-reach, and SLHOP test performance and symmetry.   The SLHOP performance differed between sexes (males = 187.8% ± 33.1% of limb length, females = 157.5% ± 27.8% of limb length; t = 30.3, P performance. We observed differences for SLHOP and ankle-dorsiflexion-lunge performance among grade levels, but these differences were not clinically meaningful.   We demonstrated differences in normative data for lower extremity functional performance during preparticipation physical evaluations across sex and grade levels. The results of this study will allow clinicians to compare sex- and grade-specific functional performances and implement approaches for preventing musculoskeletal

  2. The behavioural consequences of sex reversal in dragons

    2016-01-01

    Sex differences in morphology, physiology, and behaviour are caused by sex-linked genes, as well as by circulating sex-steroid levels. Thus, a shift from genotypic to environmental sex determination may create an organism that exhibits a mixture of male-like and female-like traits. We studied a lizard species (Central Bearded Dragon, Pogona vitticeps), in which the high-temperature incubation of eggs transforms genetically male individuals into functional females. Although they are reproductively female, sex-reversed dragons (individuals with ZZ genotype reversed to female phenotype) resemble genetic males rather than females in morphology (relative tail length), general behaviour (boldness and activity level), and thermoregulatory tactics. Indeed, sex-reversed ‘females’ are more male-like in some behavioural traits than are genetic males. This novel phenotype may impose strong selection on the frequency of sex reversal within natural populations, facilitating rapid shifts in sex-determining systems. A single period of high incubation temperatures (generating thermally induced sex reversal) can produce functionally female individuals with male-like (or novel) traits that enhance individual fitness, allowing the new temperature-dependent sex-determining system to rapidly replace the previous genetically based one.

    The teleost fish, medaka (Oryzias latipes), has an XX/XY sex-determining mechanism. A Y-linked DM domain gene, DMY, has been isolated by positional cloning as the sex-determining gene in this species. Previously, we conducted a field survey of genotypic sex and found that approximately 1% of wild medaka are sex-reversed (XX males and XY females). Here, we performed genetic analyses of nine spontaneous XX sex-reversed males to elucidate its genetic basis. In all cases, the F(1) progeny were all females, whereas XX males reappeared in the backcross (BC) progeny, suggesting that XX sex reversal is a recessive trait. Although the incidences of sex reversal in the BC progeny were mostly low, 40% were males derived from one XX male. We performed linkage analysis using 55 BC males and located a single major factor, sda-1 (sex-determining autosomal factor-1), controlling sex reversal in an autosomal linkage group. Thus, genes involved in the sex-determining pathway can be isolated from spontaneous mutants in wild populations.

    While there is agreement that sex differences in height are small up to the onset of the pubertal spurt in girls, there has been some debate about the question of which, and to what extent, various growth phases contribute to the average adult sex difference of about 13 cm. There has been no consistent agreement between authors as to what extent this difference is due to the late onset of the pubertal spurt (PS) for boys and to what extent it is due to their more intense PS. In this paper, we investigate this question for the variables height, sitting and leg height, arm length, bihumeral and biiliac width. Biiliac width is a special case since both sexes have roughly the same adult size, but girls still have a shorter growing period. The gains for boys, when compared to girls, show a very different pattern across variables: for the legs, the additional growth due to the later spurt is responsible for most of the adult sex difference (64%). On the other hand, for bihumeral width and sitting height, the more intense PS contributes almost 50% to the adult sex difference. An analysis across variables indicates that increments from 1.5 to 6 years largely compensate for deviations in infant morphology from adult morphology.

    To investigate awareness and knowledge of human papillomavirus (HPV) infection among high school students and to provide a basis for health education on HPV infection for high school students in China. A questionnaire on HPV awareness and knowledge was administered to 900 high school students in Xiangtan City of Hunan Province in China by layer cluster sampling. A total of 848 anonymous valid questionnaires were received from volunteers who completed the questionnaire correctly. Only 10.1% had heard of HPV, and of those only 18.6% knew that HPV could lead to cervical cancer. Single factor analysis indicated that home address, age, grade, academic achievement, sex history, gender, father's education level and mother's education level were impact factors for HPV knowledge of high school students. Multiple regression analysis showed 4 independent risk factors associated with HPV knowledge: academic achievement, sex history, gender, and mother's education level. The limited knowledge came primarily from television and radio broadcasts (59.3%), the Internet (57.0%), parents (25.6%), medical workers (20.9%), and teachers (18.6%). High school students lack HPV knowledge, which is affected by multiple factors. Targeted health education of all sorts must be provided. Both schools and families are responsible for reinforcing HPV education provided to high school students.

    The risk of overuse and traumatic tendon and ligament injuries differ between women and men. Part of this gender difference in injury risk is probably explained by sex hormonal differences which are specifically distinct during the sexual maturation in the teenage years and during young adulthood....... The effects of the separate sex hormones are not fully elucidated. However, in women, the presence of estrogen in contrast to very low estrogen levels may be beneficial during regular loading of the tissue or during recovering after an injury, as estrogen can enhance tendon collagen synthesis rate.

Domestic minor sex trafficking is a subset of commercial sexual exploitation of children, defined as engagement of minors (sexual acts for items of value (eg, food, shelter, drugs, money) involving children victimized within US borders. These involved youth are at risk for serious immediate and long-term physical and mental health consequences. Continued efforts are needed to improve preventive efforts, identification, screening, appropriate interventions, and subsequent resource provision for victimized and high-risk youth.

    2013-01-01

    Casual sex is often associated with the young adult stage in the life course. Most recent research on the prevalence, motives, and consequences of heterosexual casual sex has relied on samples of college students, yet students are only a small and advantaged subset of the young adult population. The current study drew on the Toledo Adolescent Relationships Study, which was collected in 2006–2007 and included young adults (ages 18–24 years) whose trajectories reflected a wider spectrum of educational experiences (N = 1,023). We moved beyond prior work by examining both frequency and type of heterosexual casual sex: lifetime vaginal, lifetime oral, and recent vaginal sex. We found that young adults enrolled or who graduated from 4-year educational institutions reported fewer casual sex partners on all three measures compared to participants with-out a high school degree and those with some college experience. Sexual attitudes were key factors mediating the association between educational status and casual sex behavior. These results indicate that programs aimed at encouraging healthy sexual behavior should target individuals who are at risk of not graduating high school because they are at greatest risk of frequent casual sex partners.

    To examine whether acculturation is associated with parent-adolescent communication about sex in Filipino-American families. Filipino-Americans, the United States' second-largest Asian and Pacific Islander (API) group, have more adolescent pregnancy and HIV infection than other APIs. High-quality parent-adolescent communication about sex has been associated with healthy sexual development, and acculturation has been associated with various increased health risks. Whether acculturation affects parent-adolescent communication is unknown. We surveyed 120 pairs of Filipino-American parents and adolescents at a single large high school. We asked adolescents about their frequency of parent-adolescent communication about sex and measured adolescent acculturation in two ways: disagreement with traditional Asian values and preferential use of English. In bivariate and multivariate regressions, we examined whether adolescent acculturation was associated with adolescent reports of parent-adolescent communication. Few adolescents (22%) reported regularly discussing sex with parents. Although most adolescents (72%) agreed with traditional Asian values, most (63%) preferred using English. In bivariate regressions, less parent-adolescent communication about sex was associated with less adolescent agreement with traditional Asian values (p = .002) and more adolescent English use (p = .009). In multivariate regressions, these associations were largely explained by adolescent perceptions of parent knowledge about their whereabouts and activities. Acculturation may influence Filipino-American parent-adolescent communication about sex and, consequently, Filipino-American adolescent sexual health. Health care and public health providers may need to tailor adolescent sexual health programs based on acculturation or other immigration-related factors.

    Becker, Jill B

    2016-12-01

    Women exhibit more rapid escalation from casual drug taking to addiction, exhibit a greater withdrawal response with abstinence, and tend to exhibit greater vulnerability than men in terms of treatment outcome. In rodents, short-term estradiol intake in female rats enhances acquisition and escalation of drug taking, motivation for drugs of abuse, and relapse-like behaviors. There is also a sex difference in the dopamine response in the nucleus accumbens. Ovariectomized female rats exhibit a smaller initial dopamine increase after cocaine treatment than castrated males. Estradiol treatment of ovariectomized female rats enhances stimulated dopamine release in the dorsolateral striatum, but not in the nucleus accumbens, resulting in a sex difference in the balance between these two dopaminergic projections. In the situation where drug-taking behavior becomes habitual, dopamine release has been reported to be enhanced in the dorsolateral striatum and attenuated in the nucleus accumbens. The sex difference in the balance between these neural systems is proposed to underlie sex differences in addiction.

    Social and economic factors determine the extent of the sex industry in societies. Despite AIDS, the sex industry will continue to thrive. Accordingly, health promotion strategies aimed at sex workers and their clients should not stem from the belief that the industry should cease to exist. This paper offers advice in developing and implementing programs to promote safer sex among sex workers. The social context is 1 element to consider in planning successful campaigns. Interventions must be combined with well-planned prevention campaigns aimed at entire populations. The opinions and participation of those involved in the industry should also be sought, while worker discussion and action upon other community issues should not be discouraged. Care should be given to target the numerous and diverse sex worker audiences in addition to other persons related to and involved in the industry. Programs should address the main obstacles to practicing safer sex, and attention should be given to ensure the provision of an adequate and regular supply of cheap or free condoms through varied distribution channels. In the area of service provision, sex workers need easy access to social support and health care services from which they are often excluded. Activities conducted around the world include the marketing of safer sex, distributing printed information on HIV and AIDS to clients, training sex workers to pass designated constructive ideas to others involved in the sex industry, referring sex workers to sex businesses supportive of safer sex practices, and developing street theater and cabaret shows in bars.

    Full Text Available Guessing and item omission may be regarded as risk-taking or risk-avoidance strategies – sex specific adaptations to testing situations. In this article, these phenomena were analysed by (a percentage of omissions by sex, (b negative binomial regression to asses sex differences in the number of omissions, (c c-DIF analysis using IRT-LR test and (d linear regression using item attributes, to assess whether the c-parameter is sex differentiated by the percentage of omits (controlling item difficulty. The data set analysed were from the 2012–2014 Polish lower-secondary schools final exams, comprising tests in maths, language, science and humanities. Contrary to the vast body of literature, boys omitted items slightly more frequently than girls. Possible explanations of this finding – specific to the Polish examination system – were provided. The hypothesis of a higher c-parameter for boys did not find strong support from this study. It was shown that the c-parameter should not only be interpreted as resulting from item non-omission. This supports the modern concept of the c-parameter as a consequence not only of random guessing, but also problem solving, creative guessing or cheating.

  1. Origin of Sex Revisited

    Why did sex ever arise in the first place? Why it does not disappear in view of the greater efficiency of asexuals? These are clearly two different questions, and we suggest here that the solution for the origin of sex does not necessarily come from theoretical considerations based on currently existing genetic systems. Thus, while we agree with a number of authors in that the emergence of sex (understood as the exchange of genetic material between genomes) is deeply rooted in the origin of life and happened during the very early stages in the transition from individual genes (`replicators') to bacteria-like cells (`reproducers'), we challenge the idea that recombinational repair was the major selective force for the emergence of sex. Taking the stochastic corrector model as a starting point, we provide arguments that question the putative costs of redundancy in primitive protocells. In addition, if genes that cause intragenomic conflict (i.e., parasites) are taken into account, it is certainly wrong to suggest that cellular fusion would be beneficial at the population level (although this strong claim needs some qualifications). However, when a continuous input of deleterious mutations that impair the fitness of the protocell as a whole is considered in the model (in the realistic range in which stable mutant distributions of quasi-species within compartments are established), there are circumstances when sex could be beneficial as a side effect of the dynamic equilibrium between cellular fusion-mutation-selection. The scenario we have explored numerically is fully consistent with the idea that the universal ancestor was not a discrete entity but an ensemble of proto-organisms that exchanged much genetic information.

    We studied the sex determination in Diachasmimorpha longicaudata, a parasitoid braconid wasp widely used as biological control agent of fruit pest tephritid flies. We tested the complementary sex determination hypothesis (CSD) known in at least 60 species of Hymenoptera. According to CSD, male or female development depends on the allelic composition of one sex locus (single-locus CSD) or multiple sex loci (multiple-locus CSD). Hemizygote individuals are normal haploid males, and heterozygotes for at least one sex locus are normal diploid females, but homozygotes for all the sex loci are diploid males. In order to force the occurrence of diploid males in D. longicaudata, we established highly inbred lines and examined their offspring using chromosome counting, flow cytometry, and sex ratio analysis. We found that when mother-son crosses were studied, this wasp produced about 20% of diploid males out of the total male progeny. Our results suggest that this parasitoid may represent the second genus with multiple-locus CSD in Hymenoptera. Knowledge about the sex determination system in D. longicaudata is relevant for the improvement of mass rearing protocols of this species. This information also provides the necessary background for further investigations on the underlying molecular mechanisms of sex determination in this species, and a better insight into the evolution of this pathway in Hymenoptera in particular and insects in general.

    Engaging in trading sex is associated with many co-occurring problems, including elevated risk for sexually transmitted infections. Various dimensions of social support from parents, schools, and mentors may be protective against sex trading and may ameliorate the impact of risk factors. This study analyzes data from respondents to Waves I and III of the National Longitudinal Study of Adolescent Health (Add Health) who had not participated in sex trading for money or drugs in Wave I so that risk and protective factors for first initiations of selling or buying sex could be examined longitudinally. About 2% of the study sample began selling sex and about 2% began buying sex between Wave I and Wave III. The respondent's sex, race/ethnicity, history of sexual abuse, shoplifting, marijuana use, and experiences of homelessness or running away were significant predictors of trading sex (p feeling part of school was associated with lower buying of sex even after controlling for demographics and risk factors (p buying sex. Promoting school connectedness may advance public health goals.

    Full Text Available We assessed the proportion of and socio-ecological factors associated with ever having had sex with female sex workers (FSWs among heterosexual adolescents. We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs.This is a cross-sectional study (response rate: 73% of 300 heterosexually active male adolescents of 16 to 19 years attending a national STI clinic in Singapore between 2009 and 2014. We assessed the ecological factors (individual, parental, peer, school and medial influences and sexual risk behaviors using a self-reported questionnaire. Poisson regression was used to obtain the adjusted prevalence ratios (aPR and confidence intervals (CI.The proportion of heterosexual male adolescents who had ever had sex with FSWs was 39%. Multivariate analysis showed that significant factors associated with ever having had sex with FSWs were sex initiation before 16 years old (aPR 1.79 CI: 1.30-2.46, never had a sexually active girlfriend (aPR 1.75 CI 1.28-2.38, reported lower self-esteem score (aPR 0.96 CI: 0.93-0.98, higher rebelliousness score (aPR 1.03 CI: 1.00-1.07 and more frequent viewing of pornography (aPR 1.47 CI: 1.04-2.09. Lifetime inconsistent condom use with FSWs was 30%.A significant proportion of heterosexual male adolescents attending the public STI clinic had ever had sex with FSWs. A targeted intervention that addresses different levels of influence to this behavior is needed. This is even more so because a considerable proportion of adolescents reported inconsistent condom use with FSWs, who may serve as a bridge of STI transmission to the community. National surveys on adolescent health should include the assessment of frequency of commercial sex visits and condom use with FSWs for long-term monitoring and surveillance.

    Full Text Available Background: Rubella vaccination is not yet included in National Immunization Schedule in India. Serosurvey is frequently used to assess epidemiologic pattern of Rubella in a community. Serosurveys in different parts of India have found that 6-47% of women are susceptible for Rubella infection. The present serosurveillance was conducted in Jammu, India, in two public schools. Objective: To determine serological status of Rubella antibodies of school girls and assessment of immunogenicity and reactogenicity of Rubella immunization in seronegative girls. Materials and Methods: The current study was conducted to determine Rubella serostatus in peripubertal schoolgirls aged 11-18 years and also to assess immunogenicity and safety of Rubella vaccine (R-Vac of Serum Institute of India Ltd., Pune, in seronegative girls. For screening, pre-vaccination serum Rubella IgG antibodies were determined and to assess immunogenicity of the vaccine, post-vaccination IgG antibodies were compared with pre-vaccination levels. Safety assessment was done for a period of 8 weeks, post-vaccination. Results: A total of 90 (32.7% seronegative girls were vaccinated. All girls (100% became seropositive, post-vaccination. Clinically relevant and statistically significant increase in anti-Rubella IgG titres was observed. The adverse events were mild and self-limiting. Conclusions: R-Vac vaccine used in the study demonstrated an excellent safety and immunogenicity profile.

    Full Text Available Determination of sex from skeletal remains is performed using a number of methods developed by biological anthropology. They must be evaluated for consistency and for their performance in a forensic setting. Twenty skeletons of varied provenance had their sex determined by 15 existing methods of forensic anthropology (7 metric and 8 morphological. The methods were evaluated for their consistency in determination of sex. No single individual was identified as belonging to one sex exclusively. Ambiguous results were obtained by metric methods for fourteen individuals (70% and by morphological methods for only five individuals (25% (Chi-squared = 4.3, df = 1, P<0.05. Methods which use the size of bones as an indicator of sex perform poorly on skeletal remains of individuals of unknown provenance. Methods which combine morphologic and metric techniques, that is, geometric morphometric analysis, may result in greater levels of consistency.
