Investigative Interviewing of Aboriginal children in cases of suspected sexual abuse

This study examined the investigative interviewing of Australian Aboriginal children in cases of alleged sexual abuse, with a focus on three commonly included components of interview protocols: ground rules, practice narrative, and substantive phase. Analysis of 70 field transcripts revealed that the overall delivery and practice of ground rules at the beginning of the interview was positively associated with the spontaneous usage of rules in children's narratives of abuse. When specifically examining the "don't know" rule, however, only practice had an effect of children's usage of the rule (as opposed to simple delivery or no delivery at all). Children spoke more words overall, and interviewers used more open-ended prompts during the substantive phase when the interviews contained a practice narrative. Children most often disclosed sexual abuse in response to an open-ended prompt; however, they produced the most words in response to suggestive prompts. This article concludes with a discussion of the effectiveness of ground rules, practice narratives, and questioning with Aboriginal children.

Poorer subjective sleep quality is related to higher fantasy-induced sexual arousal in women of reproductive age

Lack of sleep enhances erections and lubrication the next day. This raises the possibility that poorer subjective sleep quality is related to sexual arousal. To test this hypothesis, sexual arousal was elicited in 70 Portuguese women of reproductive age by means of fantasy. The level of salivary testosterone before and shortly after fantasy was determined by luminescence immunoassays. Participants completed the Pittsburgh Sleep Quality Index (PSQI), reported their sexual arousal before and during fantasy, and how anxious they were after the fantasy. The hypothesis was confirmed. Anxiety did not explain the association, but testosterone response (poststimulus minus baseline) had a slight explanatory effect.

Sexual selection predicts brain structure in dragon lizards

Phenotypic traits such as ornaments and armaments are generally shaped by sexual selection, which often favours larger and more elaborate males compared to females. But can sexual selection also influence the brain? Previous studies in vertebrates report contradictory results with no consistent pattern between variation in brain structure and the strength of sexual selection. We hypothesize that sexual selection will act in a consistent way on two vertebrate brain regions that directly regulate sexual behaviour: the medial preoptic nucleus (MPON) and the ventromedial hypothalamic nucleus (VMN). The MPON regulates male reproductive behaviour whereas the VMN regulates female reproductive behaviour and is also involved in male aggression. To test our hypothesis, we used high-resolution magnetic resonance imaging combined with traditional histology of brains in 14 dragon lizard species of the genus Ctenophorus that vary in the strength of precopulatory sexual selection. Males belonging to species that experience greater sexual selection had a larger MPON and a smaller VMN. Conversely, females did not show any patterns of variation in these brain regions. As the volumes of both these regions also correlated with brain volume (BV) in our models, we tested whether they show the same pattern of evolution in response to changes in BV and found that the do. Therefore, we show that the primary brain nuclei underlying reproductive behaviour in vertebrates can evolve in a mosaic fashion, differently between males and females, likely in response to sexual selection, and that these same regions are simultaneously evolving in concert in relation to overall brain size.

Asociación de las violencias física, sexual y comunitaria con el embarazo en adolescentes: análisis multinivel

Objetivos Determinar si existe asociación entre la exposición a violencia, experimentada a nivel individual o municipal, y el embarazo adolescente en mujeres Colombianas entre 13 y 19 años de edad que contestaron la Encuesta de Demografía y Salud en el año 2010. Métodos Estudio de corte transversal, nacional y multinivel. Se tomaron datos de dos niveles jerárquicos: Nivel- 1: Datos individuales de una muestra representativa de 13.313 mujeres entre 13 y 19 años de edad provenientes de La Encuesta Nacional de Demografía y Salud del año 2010 y Nivel- 2: Datos municipales de 258 municipios provenientes de las estadísticas vitales del DANE. Resultados La prevalencia del embarazo adolescente fue del 16.8% IC 95% [16.2-17.4]. El análisis mostró que la asociación entre embarazo adolescente y violencia tanto individual, representada como violencia sexual [OR= 6.99 IC99% 4.80-10.10] y violencia física [OR= 1.74 IC99% 1.47-2.05] así como la violencia municipal medida con tasas de homicidios altas [OR= 1.99 IC99% 1.29-3.07] y muy altas [OR= 2.10 IC99% 1.21-3.61] se mantuvo estadísticamente significativa después de ajustar por las variables: Edad [OR= 1.81 IC99% 1.71-1.91], ocupación [OR= 1.62 IC99% 1.37-1.93], educación primaria o sin educación [OR= 2.20 IC99% 1.47-3.30], educación secundaria [OR= 1.70 IC99% 1.24-2.32], asistir al colegio [OR= 0.18 IC99% 0.15-0.21], conocimiento en la fisiología reproductiva [OR= 1.28 IC99% 1.06-1.54], el índice de riqueza Q1, Q2, Q3 [OR= 2.18 IC99% 1.42-3.34], [OR= 2.00 IC99% 1.39-2.28], [OR= 1.82 IC99% 1.92-2.25] y alto porcentaje de Necesidades básicas insatisfechas a nivel municipal [OR= 2.34 IC99% 1.55-3.52]. Conclusiones Este estudio mostró una relación significativamente estadística entre la violencia sexual y física con el inicio de relaciones sexuales y embarazo adolescente después de controlar por factores sociodemográficos y conocimientos en reproducción sexual en mujeres colombianas de 13 a 19 años en el año 2010. Esta asociación debe continuar siendo estudiada para lograr optimizar las estrategias de prevención y disminuir la tasa actual de embarazos adolescentes en el país y sus consecuencias.

El abuso sexual a niñas, niños y adolescentes: un secreto familiar, un problema familiar, un problema social

This investigation has the purpose of identifying how to prevent through educational processes, and then eradicate, the sexual abuse against children and adolescents in rural communities from Salvador, Guatemala, Honduras and Nicaragua. The premise is that sexual abuse cannot be approached in an isolated way; it requires integral and committed actions of the institutions in charge of children and adolescents’ integral protection and development. This implies considering: the legal framework, the response offered by government and private organizations towards the prevention and attention of rights as well as their actions to penalize and restore the violated rights; the role of families as main responsible of the well being of their children and the role of children and adolescents.

BACKLASH Y ABUSO SEXUAL INFANTIL: LA EMERGENCIA DE NUEVAS AMENAZAS A LA PROTECCIÓN DE LOS DERECHOS HUMANOS DE LAS PERSONAS MENORES DE EDAD

ResumenEl presente artículo se propone como una disertación en torno al fenómeno del abuso sexual infantily el Backlash, comprendiendo a este último como un contra-movimiento social que buscalegitimar diversas manifestaciones de violencia en contra de las mujeres y las personas menoresde edad. En aras de alcanzar dicho propósito, el artículo parte de la conceptualización del términoabuso sexual infantil, resaltando sus principales características y consecuencias, continúa con unadiscusión conceptual en torno al Backlash y sus principales derivaciones y concluye con una reflexiónrespecto a la relación entre este y el abuso sexual infantil. Producto del recorrido emprendido seafirma que, si bien el Backlash nace como una respuesta contraria y contestataria al éxito obtenidopor el movimiento de mujeres, ha evolucionado e incursionado en otras áreas temáticas, como lo esel abuso sexual infantil, cuya comprensión y atención se ha visto influenciada por teorías “pseudocientíficas” como el síndrome de alienación parental y el síndrome de falsas memorias, desde lascuales se desacredita la revelación de las víctimas. En tanto el uso de teorías compatibles con elBacklash en procesos de custodia y juicios por denuncias de abuso sexual se encuentra en aumentovertiginoso, se concluye que el movimiento de derechos humanos debe fortalecer una respuestaconjunta y sólida frente a esta reacción extrema.AbstractThe present article is a dissertation proposal regarding the child sexual abuse phenomenon and the Backlash, being the last a social countermovement which pretends to legitimize various manifestations of violence towards women and underage people. The article starts from the conceptualization of the term child sexual abuse, highlighting its key characteristics and consequences, moving on to a conceptual discussion concerning Backlash and its main derivations, and ending in a reflection about its relationship with child sexual abuse. From the research undertaken it is stated that, while Backlash started out as a counter response to the success achieved by the women movement, it has evolved and moved into other thematic areas, such as child sexual abuse, which understanding and focus have been influenced by pseudoscientific theories like the parental alienation syndrome and the false memory syndrome, from which the victims’ declarations are discredited. While the use of Backlash compatible theories in custody processes and sexual abuse accusation trials shows an accelerated increase, it is concluded that the human rights movement needs to build up a solid and joint answer against this extreme response.Keywords:Backlash, child sexual abuse, parental alienation syndrome, false memories syndrome.
