Child sexual abuse: Raising awareness and empathy is essential to promote new public health responses

Child sexual abuse is a major global public health concern, affecting one in eight children and causing massive costs including depression, unwanted pregnancy and HIV. The gravity of this global issue is reflected by the United Nations’ new effort to respond to sexual abuse in the 2015 Sustainable Development Goals. The fundamental policy aims are to improve prevention, identification and optimal responses to sexual abuse. However, as shown in our literature review, policymakers face difficult challenges because child sexual abuse is hidden, psychologically complex, and socially sensitive. This article contributes significant new ideas for international progress. Insights about required strategies are informed by an innovative multidisciplinary analysis of research from public health, medicine, social science, psychology, and neurology. Using an ecological model comprising individual, institutional and societal dimensions, we propose that two preconditions for progress are the enhancement of awareness of child sexual abuse, and of empathic responses towards its victims.

Child sexual abuse and access to justice for civil claims: Time to reform the Limitation of Actions Act 1974 (Qld)

In 2015, Victoria passed laws removing the time limit in which a survivor of child sexual abuse can commence a civil claim for personal injury. The law applies also to physical abuse, and to psychological injury arising from those forms of abuse. In 2016, New South Wales made almost identical legal reforms. These reforms were partly motivated by the recommendations of inquiries into institutional child abuse. Of particular relevance is that the Australian Royal Commission Into Institutional Responses to Child Sexual Abuse recommended in 2015 that all States and Territories remove their time limits for civil claims. This presentation explores the problems with standard time limits when applied to child sexual abuse cases (whether occurring within or beyond institutions), the scientific, ethical and legal justifications for lifting the time limits, and solutions for future law reform.

Dung as a potential medium for inter-sexual chemical signaling in Asian elephants (Elephas maximus)

Chemical signaling is a prominent mode of male-female communication among elephants, especially during their sexually active periods. Studies on the Asian elephant in zoos have shown the significance of a urinary pheromone (Z7-12:Ac) in conveying the reproductive status of a female toward the opposite sex. We investigated the additional possibility of an inter-sexual chemical signal being conveyed through dung. Sixteen semi-captive adult male elephants were presented with dung samples of three female elephants in different reproductive phases. Each male was tested in 3 separate trials, within an interval of 1-3 days. The trials followed a double-blind pattern as the male and female elephants used in the trials were strangers, and the observer was not aware of the reproductive status of females during the period of bioassays. Males responded preferentially (P < 0.005), in terms of higher frequency of sniff, check and place behavior toward the dung of females close to pre-ovulatory period (follicular-phase) as compared to those in post-ovulatory period (luteal-phase). The response toward the follicular phase samples declined over repeated trials though was still significantly higher than the corresponding response toward the non-ovulatory phase in each of the trials performed. This is the first study to show that male Asian elephants were able to distinguish the reproductive phase of the female by possibly detecting a pre-ovulatory pheromone released in dung.

Evaluación de semilla sexual hibrida de papa (Solanum tuberosum L.) provenientes del Centro Internacional de la Papa e India en la zona de Miraflor, Esteli

Con el objetivo de seleccionar progenies promisorias de semilla sexual de papa, procedentes del CIP (11) y Programa de la India (3) se estableció este ensayo el 21 de septiembre de 1994, utilizando un diseño de Bloques Completos al Azar (BCA) con cuatro repeticiones, en la estación experimental del Instituto Nicaragüense de Tecnología Agropecuaria (INTA-RB-3), ubicada a 1 350 msnm, humedad relativa del 91 por ciento, temperatura promedio mínima 15 °C/máx 26 °C, cuyos suelos son de textura franca bien drenada, medianamente profundo a profundo, con una precipitación durante el ensayo de 622 mm. Los resultados obtenidos muestran que todas las progenies híbridas enviadas por el CIP mostraron buena velocidad de emergencia en especial SERRANA x LT-7, con respecto a los lubridos de la India. En general el porcentaje de sobrevivencia fue mayor del 80 por ciento para la mayoría de las progenies el cual es un índice aceptable, a excepción de 104.12 LB x TS-4.En la altura final de la planta no hubieron diferencias significativas entre híbridos, solo fueron superiores a KATADIN x TS-10. En cuanto al rendimiento, la progenie HPS­ II/67 mostró ser superior a las demás con 6.2 kg/m2. El número total de tubérculos por metro cuadrado {740) y tubérculos por planta (7) fue superior en la progenie TS-6 x TPS-67. Las progenies de ambos programas mostraron rendimientos por metro cuadrado de más del 50 por ciento con tubérculos mayores de 5 gramos. No se presentó incidencia de virus para ambas progenies, las tres progenies provenientes del Programa de la India presentaron mayor resistencia a tizón tardío (Phytophthora infestans, Mont. D.bary).

Evaluacion de diferentes niveles de fertilizantes NPK en la produccion de minituberculos de papa (Solanum tuberosum L.) en semillero para la producción comercial, proveniente de semilla sexual, variedad ATZIMBA

La papa es una fuente de alimentación importante a nivel mundial, en Nicaragua los altos costos de importación de semilla de buena calidad, tiene como efecto, la dificultad de los productores de aumentar áreas de siembra y el bajo consumo con respecto a otros países por el costo de este producto. La falta de un programa nacional de producción de semilla contribuye al problema, ya que muchos productores no tienen acceso a semilla, pero al introducir la semilla botánica de papa para producción de minituberculos, hace que el productor demande nuevos conocimientos, por tanto hay que desarrollarlos, uno de estos conocimientos es la dosis de fertilización adecuada en semillero de papa para la producción de minituberculos. Existen estudios en otros países como Perú, pero no son adaptables a nuestras condiciones, por tal motivo se estableció un ensayo en el Mojón, Jinotega, el cual comprendió de septiembre a diciembre del 2002, el diseño utilizado fue el de Bloques Completos al Azar (BCA), donde se evaluaron cinco dosis de fertilizantes. El área experimental fue de 105 m2, la comparación de medias se realizo por Duncan al 0.05 de probabilidad. Los objetivos del ensayo fueron: objetivo general: Evaluar el efecto de distintos niveles de fertilización sobre la producción de mini tubérculos de papa (Solanum tuberosum L.) en semillero, proveniente de semilla sexual o semilla verdadera. Objetivos específicos: Estudiar el efecto de diferentes dosis de fertilizantes en almacigo para la producción de minituberculos de papa, determinar la dosis con las que se obtienen los mejores rendimientos en la producción de minituberculos de papa, y realizar un análisis Beneficio–Costo de los resultados obtenidos para determinar cual es el tratamiento que económica y productivamente es el más rentable. Los parámetros evaluados fueron: altura de plantas, plantas cosechadas, cuatro categorías de peso de tubérculos y número de tubérculos totales por hectárea, además el rendimiento de minitubérculos de papa. No se encontró evidencia estadísticas que alguna dosis aumente el numero de tubérculos por hectárea, pero, se demostró que la aplicación de 300 a 450 kilogramos de urea, 270 a 420 kilogramos del fertilizante 18-46-00 y 80 a 130 kilogramos de sulfato de amonio aumenta el rendimiento en peso de minitubérculos, y la ganancia de los productores aumenta de 133 000 a 139 300 córdobas por hectárea. Aplicaciones mayores de fertilizantes causan perdidas hasta en 41 600 córdobas por hectárea con respecto a la aplicación de los productores.

Studies of the age, growth, sexual maturity and spawning of populations of anchoveta (Cetengraulis mysticetus) of the coast of the Eastern Tropical Pacific Ocean

ENGLISH: Three hundred and twenty-six collections of anchoveta (Cetengraulis mysticetus), an important tuna bait species, taken between April 1951 and April 1960 from seven major baiting areas in the Eastern Tropical Pacific Ocean (Almejas Bay, Guaymas, Ahome Point, Banderas Bay, Gulf of Fonseca, coast of Colombia and Ecuador-Peru) are the basis of this study of age, growth, sexual maturity and spawning. The study of the temporal progression of modal size groups from plots of monthly length-frequency distributions provided estimates of age and rate of growth. The study of sexual maturity and time of spawning was based on gross examination of ovaries, and application of the gonad index. SPANISH: Trescientas veintiseis recolecciones de anchovetas (Cetengraulis mysticetus), una importante especie de carnada para la pesca del atún, cogidas entre abril de 1951 y abril de 1960 en siete de las mayores áreas de pesca de peces de carnada en el Océano Pacífico Oriental Tropical (Bahía de Almejas, Guaymas, Punta Ahome, Bahía Banderas, Golfo de Fonseca, y las costas de Colombia y de Ecuador- Perú), sirven de base a este estudio de la edad, crecimiento, madurez sexual y desove de dicha especie. El estudio de la progresión temporal de los grupos de tamaños modales según los gráficos de las distribuciones de la frecuencia de las longitudes proporcionó estimaciones de la edad y de la tasa de crecimiento. La investigación de la madurez sexual y la época de desove se basó en el examen macroscópico de los ovarios y en la aplicación del índice de gónadas.

Sexual Reproduction and Early Development in the Estuarine Sea Anemone, Nematostella vectensis Stephenson, 1935

This dissertation: 1) determines the factor(s) responsible for spawning induction in NematosteJla vectensis; 2) isolates, describes, and documents the source of jelly from egg masses of N. vectensis; and 3) describes N. vectensis' early development. Namatostella vectensis were maintained on a 7-day mussel feeding/water change regime over 159 days. Within 36 hours of mussel feeding/water change. 69.1% of females and 78.5% of males spawned reliably. Through manipulation of feeding, water change, oxygen and nitrogenous waste concentrations, spawning induction was found to be triggered by the oxygen concentration associated with water change, and not by feeding. Ammonia, anemones' major waste product, inhibited this induction in a concentration-dependent manner. Female N. vectensis release eggs in a persistent jellied egg mass which is unique among the Actiniaria. The major component of this egg mass jelly was a positive periodic acid-Schiffs staining, 39.5-40.5 kD glycoprotein. Antibodies developed in rabbits against this glycoprotein bound to jelly of intact egg masses and to granules (~ 2.8 IJm in diameter) present in female anemone mesenteries and their associated filaments. Antibodies did not label male tissues. Nematostella vecfensis embryos underwent first karyokinesis -60 minutes following the addition of sperm to eggs. Second nuclear division took place, followed by first cleavage, 90-120 minutes later. Each of the 4 blastomeres that resulted from first cleavage contained a single nucleus. Arrangement of these blastomeres ranged from radial to pseudospiral. Embryonic development was both asynchronous and holoblastic. Following formation of the 4-cell stage, 71% of embryos proceeded to cleave again to form an 8-cell stage. In each of the remaining 29% of embryos, a fusion of from 2-4 blastomeres resulted in 4 possible patterns which had no affect on either cleavage interval timing or subsequent development. The fusion event was not due to ooplasmic segregation. Blastomeres isolated from 4-celled embryos were regulative and developed into normal planula larvae and juvenile anemones that were 1/4 the size of those that developed from intact 4-celled embryos. Embryos exhibiting the fusion phenomenon were examined at the fine structural level. The fusion phenomenon resulted in formation of a secondary syncytium and was not a mere compaction of blastomeres.

Size composition, growth and sexual maturity of bigeye tuna, Thunnus obesus (Lowe), from the Japanese long-line fishery in the Eastern Pacific Ocean

Size composition data of bigeye tuna taken from the eastern tropical Pacific Ocean by Japanese Prefectural experimental training vessels from 1958 to 1964 are examined. A gradient of increasing fish size from east to west is noted. Males increase in ratio over females for the entire range of lengths examined, and beyond 170 cm comprise more than 75 per cent of the total. The first semester of the year is important as a bigeye spawning season. A general relationship between sexual maturity and thermal structure of the water is discussed. At the end of their 12th quarter of life bigeye are about 114 cm long, by the 16th quarter, 137 cm and at the end of 20 quarters, about 153 cm. The long-line fishery in the eastern Pacific has had a marked effect on the size composition of the stocks of bigeye, but whether the fishing has driven the stocks below a point which could afford a maximum sustainable yield could not be determined.

Studies of the sexual development and spawning of yellowfin tuna, Neothunnus macropterus, and skipjack, Katsuwonus pelamis, in three areas of the Eastern Pacific Ocean, by examination of gonads.

ENGLISH: Knowledge of the size and age at maturity, spawning seasons, and spawning areas of the tropical tunas supporting the fishery in the Eastern Pacific is an important part of the basic information required for understanding their life history, population structure, and fishery dynamics. Until a few years ago nothing was known of these matters. In 1947 the senior author and one of his colleagues (Schaefer and Marr 1948, Schaefer 1948) were able to demonstrate that both yellowfin tuna and skipjack spawn offshore from Central America at least during the late winter and spring months. During January to April many yellowfin tuna over about 70 cm. total length in commercial catches from that region were found to have gonads in advanced stages of maturity, and specimens caught during late June were found to be spent. Maturing skipjack were collected in late February, and spawned-out fish were observed in late March. Numerous very young juveniles of the yellowfin, down to 10 mm. in length, and two very young juvenile skipjack, were captured in this area between January and May. SPANISH: El conocimiento del tamaño y la edad que corresponden a la primera madurez sexual, así como de las estaciones y áreas de desove de los atunes tropicales que mantienen las pesquerías del Pacífico Oriental, constituyen parte importante de la información que es menester para comprender la historia natural, la estructura de la población y la dinámica de la pesquería. Hasta hace pocos años nada se sabía sobre el particular. En 1947 el autor principal y uno de sus colegas (Schaefer y Marr, 1948; Schaefer, 1948) pudieron demostrar que tanto el atún aleta amarilla como el barrilete desovan en el mar abierto, frente a América Central, por lo menos durante la última parte del invierno y en la primavera. De enero a abril encontraron que muchos de los atunes aleta amarilla de más de 70 cm. de longitud total, procedentes de las pescas comerciales de dicha región; tenían gónadas en avanzados estados de madurez, mientras que ejemplares pescados hacia fines de junio ya habían desovado. Se recolectaron barriletes en vías de maduración a fines de febrero, al paso que en los últimos días de marzo se encontraron especímenes que ya habían desovado. Numerosos ejemplares muy juveniles del atún aleta amarilla, tan pequeños como 10 mm., y dos barriletes también muy juveniles, fueron pescados en esta región entre enero y mayo.

A study of the age, growth, sexual maturity, and spawning of the anchoveta, Cetengraulis mysticetus, in the Gulf of Panama

ENGLISH: Crew members of tuna clippers and Commission personnel are collecting specimens of anchovetas (Cetengraulis mysticetus) for studies of the biology of this important tuna-bait species. More than 27,000 fish from 231 collections captured in the Gulf of Panama between June 1951 and January 1956 are the basis of this study of the age, growth, sexual maturity, and spawning season of this species in that area. Estimates of age and rate of growth were made by studying the temporal progression of modal size groups from monthly length frequency distributions. Sexual development and time of spawning were determined from gross examination of ovaries and measurements of ovarian eggs. SPANISH: Con el fin de estudiar la biología de la anchoveta (Cetengraulis mysticetus) los tripulantes de los barcos atuneros y el personal de la Comisión están recolectando especimenes de esta importante especie de carnada para capturar el atún. Mas de 27,000 ejemplares de las 231 colecciones hechas en el Golfo de Panamá entre junio de 1951 y enero de 1956, sirven de material al presente estudio sobre la edad, el crecimiento, la madurez sexual y las épocas de desove de esta especie en el área indicada. Las estimaciones de la edad y de la proporción del crecimiento fueron hechas a base del estudio de la progresión temporal de los grupos modales de tamaño en las distribuciones mensuales de frecuencias de longitud. El desarrollo sexual y el periodo de desove fueron determinados mediante el examen microscópico de los ovarios y las mediciones de los huevos ováricos. (PDF contains 79 pages.)

Sexual maturity, fecundity and egg size of wild and cultured samples of Bagrus bayad macropterus

Twenty four matured samples of Bagrus bayad macropterus from the wild (Shiroro Lake, Nigeria) and under captivity, size ranging from 412.69-3300.00 g total body weight, were analysed for sexual maturity,fecundity and egg size. The average fecundity obtained were 53352.59 and 21028.32 eggs for the wild and cultured fish respectively.Positive relationship was observed between fecundity, body size and gonad weight. Fecundity increased as body size increased. A more positive and linear relationship was observed between fecundity and gonad weight than fecundity and total body weight. Egg diameter,length and weight were determined from the egg samples. The mean size range of eggs for cultured fish was 0.74-1.05 mm of diameter; 1.01-1.20 mm of length and 0.25-0.40 mg of weight. Wild samples had mean size range of 0.68-l.09 mm of diameter, 0.85-1.38 mm of length and egg mean weight range was 0.15- 0.40 mg. Sexual maturity is dependent on size (1 kg and above). The egg diameter, egg length and weight bear no relationship with each other. Gonad development study indicated that gonad development was faster under captivity than in wild

Prevalência de HPV em adolescentes virgens e com atividade sexual

O Papilomavírus humano (HPV) é um vírus DNA bastante prevalente em estimativas mundiais, sendo a DST isolada mais frequente no mundo. Existem poucos dados sobre prevalência em adolescentes sem vida sexual ativa, havendo ainda muitos tabus nesta faixa etária. O presente estudo tem por objetivo identificar a prevalência de Papilomavírus humano através de biologia molecular em pacientes sem coitarca, comparando com um grupo de pacientes da mesma faixa etária com atividade sexual. Foram avaliadas 100 adolescentes com idade variando de 11 a 20 anos, com pelo menos dois anos pós-menarca, atendidas no período de janeiro de 2007 a janeiro de 2009 no ambulatório de ginecologia infantopuberal do Hospital Universitário Pedro Ernesto. Das 100 adolescentes, 50 apresentavam hímen íntegro e 50 relatavam atividade sexual regular. Para as pacientes sem coitarca (grupo 1) foi realizada uma coleta apenas de vestíbulo e para as pacientes com atividade sexual (grupo 2) foi realizada coleta de vagina e endocérvice. A pesquisa de DNA-HPV foi realizada por captura híbrida de 2 geração. Os resultados foram descritos em unidade relativa de luz. Para os dados categóricos foram aplicados os testes exato de Fisher. A positividade geral de DNA de HPV de alto e de baixo risco foi de 72%. No grupo 1 houve positividade do teste em 3 casos (6%). Já no grupo 2, 33 casos (66%) foram positivos para pelo menos um sítio. Material de vagina foi positivo em 30 casos (60%) e de colo em 27 casos (54%). Pode-se concluir que a positividade nas meninas com vida sexual ativa é alta. A infecção pelo HPV, ainda que pouco frequente, pode estar presente em meninas sem coitarca.
