A comparison of self-reported puberty using the pubertal development scale and the sexual maturation scale in a school-based epidemiologic survey

Purpose: To examine concordance between two self-reported measures of puberty: Sexual Maturatiom Scale (SMS) and Pubertal Developl1!ent Scale (PDS) and their acceptability to adolescents. Methods: Participants of a school-based study in grades 5, 7 and 9 were classified into one of 5 pubertal stages using each method. Results: 2864 students (age 9-16 years) participated. Agreement was moderate for males (K 0.42, 95% CI 0.39,0.45) and females (K 0.57, 95% CI 0.53, 0.61). Concordance within one stage was excellent (females 97%, males 89%), with discrepancies due to females being classified one stage later on the PDS (26%) and males one stage earlier (32%). There were more missing data for the SMS (13%) than the PDS (4%).

Sexual sites, seminal attitudes : sexualities, masculinities, and culture in South Asia

This book situates current research into the sexual cultures of South Asia within a cross-cultural perspective. The book argues that in societies undergoing rapid social and cultural change, the construction of sexuality and the discourses that gather around it have a fundamental connection with an entire range of processes - social, cultural, economic, political and global - with which people must engage. The contributors have studied sexuality as a site around which social and cultural ideas may be expressed.

Psychological and interpersonal dimensions of sexual function and dysfunction.

To highlight the salient psychological and interpersonal issues contributing to sexual health and dysfunction; to offer a four-tiered paradigm for understanding the evolution and maintenance of sexual symptoms; and to offer recommendations for clinical management and research.

A case study of child sexual abuse within a Church community

A case study is presented of child sexual assault within a church community. How does a church community deal with the accusation of an adolescent female that-as a 13-year old-she was sexually victimised and assaulted by her then 18-year old boyfriend, five years her senior? Practical and pastoral issues, as well as ethical and legal concerns are addressed. Consideration is also given to the theological context of the church environments in which the situations arise. The implications for victims, perpetrators, leaders, and the church community of our actions-and failure to take appropriate action-are described, along with recommendations for prevention, and best practice in dealing with the sexual abuse of minors within church communities.

Sexual segregation in western grey kangaroos: testing alternative evolutionary hypotheses

In sexually dimorphic ungulates, sexual segregation is hypothesized to have evolved because of sex-specific differences in body size and/or reproductive strategies. We tested these alternative hypotheses in kangaroos, which are ecological analogues of ungulates. Kangaroos exhibit a wide range of body sizes, particularly among mature males, and so the effects of body size and sex can be distinguished. We tested predictions derived from these hypotheses by comparing the distribution of three sex–sex size classes of western grey kangaroos Macropus fuliginosus, in different habitats, and the composition of groups of kangaroos, across seasons. In accordance with the predation risk-reproductive strategy hypothesis, during the non-breeding season, females, which were more susceptible to predation than larger males, and were accompanied by vulnerable young-at-foot, were over-represented in secure habitats. Large males, which were essentially immune to predation, occurred more often than expected in nutrient-rich habitat, and small males, which faced competing demands of predator avoidance and feeding, were intermediate between females and large males in their distribution across habitats. During the breeding season, females continued to be over-represented in secure habitats when their newly emerged pouch young were most vulnerable to predation. All males occupied these same habitats to maximize their chances of securing mates. Consistent with the social hypotheses, groups composed of individuals of the same sex, irrespective of body size, were over-represented in the population during the non-breeding season, while during the breeding season all males sought females so that mixed-sex groups predominated. These results indicate that body size and reproductive strategies are both important, yet independent, factors influencing segregation in western grey kangaroos.
