Abstract: With increased globalization, Latin America is experiencing transitions from traditional lifestyle and dietary practices to those found in higher income countries. Healthy diets, physical activity and optimal body fat can prevent approximately 15% of cancers in low-income and 20% in high-income countries. We discuss links between diet, obesity, physical activity and cancer, emphasizing strategies targeting children to decrease risk of obesity, control obesity-related risk factors, and reduce sedentary lifestyles, as this will have high impact on adult cancer risk. We focus on individual behaviors, economic, cultural and societal changes that may guide future interventions in the Americas.

Resumen: América Latina está experimentando transiciones desde estilos de vida tradicional y prácticas dietéticas a las de países de ingresos altos. Las dietas saludables, la actividad física y la grasa corporal óptima pueden prevenir aproximadamente el 15% de cánceres en países de bajos ingresos y 20% en países de ingresos altos. Discutimos los vínculos entre la dieta, obesidad, actividad física y cáncer; haciendo hincapié en estrategias dirigidas a niños, para disminuir el riesgo de obesidad y reducir la vida sedentaria. Nos enfocamos en comportamientos individuales, cambios económicos, culturales y sociales que pueden guiar futuras intervenciones en las Américas.

Abstract The appropriate choice of tree species and planting arrangement for use in agroforestry systems is very important in order to maximize productivity and sustainability. The aim of this study was to evaluate the growth of five tree species and its effect on sugarcane yields in different planting arrays in agroforestry systems. The study was conducted from 2007 to 2011 in the city of Frederico Westphalen, RS, Brazil. The five studied tree species were: guapuruvu (Schizolobium parahybae), bracatinga (Mimosa scabrella), canafístula (Peltophorum dubium), angico-vermelho (Parapiptadenia rigida) and eucalypt (Eucalyptus urophylla S.T. Blake x Eucalyptus grandis Hill ex Maiden). Root collar diameter, diameter at breast height, plant height and mean diameter of crown were evaluated for four years with an interval of 90 days between assessments. Yield data for sugarcane were collected in June 2009, 2010, and 2011. Eucalypt presented the greatest root collar diameter values, diameter at breast height, crown development, and plant height. Angico-vermelho, canafístula and eucalypt presented a higher growth in the strip system, while guapuruvu presented the greater growth in the line system. Bracatinga was not influenced by an arrangement in the agroforestry systems. Sugarcane presented greater production in the understory of angico and bracatinga.

Abstract This article analyses John Hillcoat's 2005 film The Proposition in relation to a spate of Australian films about violence and the (post)colonial encounter released in the early twenty-first century. Extending on Felicity Collins and Therese Davis argument that these films can be read in terms of the ways they capture or refract aspects of contemporary race relations in Australia in a post-Mabo, this article analyses how The Proposition reconstructs the trauma of the Australian frontier; how from the perspective of the twenty-first century it worries over the meaning of violence on the Australian frontier. It also explores what has become speakable (and remains unspeakable) in the public sphere about the history of the frontier encounter, especially in terms of family and race. The article argues that The Proposition and other early twenty-first century race relations films can be understood as post-reconciliation films, emerging in a period when Indigenous and non-Indigenous Australians were rethinking ideas of belonging through a prism of post-enmity and forgiveness. Drawing on the theme of violence and intimate relations in the film, this article argues that the challenges to the everyday formulation of Australian history proffered in The Proposition reveal painful and powerful differences amongst Australian citizens' understanding of who belongs and how they came to belong to the nation. I suggest that by focusing on violence in terms of intimacy, relationships, family and kin, it is possible to see this film presented an opportunity to begin to refigure ideas of belonging.

O estudo teve como objetivo avaliar a viabilidade de Heterorhabditisamazonensis isolado RSC-5 após exposição a diferentes carrapaticidas utilizados no controle de Rhipicephalusmicroplus. Foram constituídos seis tratamentos, cada um composto por um produto, sendo cada grupo com 75.000 nematoides (NEPs) em suspensão de 20 mL de solução de diferentes carrapaticidas, em concentração comercial. O controle foi formado por 75.000 NEPs e 20 mL de água destilada, e todos os grupos foram mantidos em câmara climatizada a 25°C. A avaliação do percentual de sobrevivência e infectividade em lagartas Galleria mellonella foi realizada 24 e 72 horas após o início do experimento. A mortalidade de lagartas no teste de infectividade foi analisada após 72 e 120 horas. Com 24 horas de exposição, o percentual de sobrevivência de H. amazonensis RSC-5 não foi significativamente reduzido (p > 0,05) somente na exposição ao princípio ativo deltametrina. O mesmo foi observado no período de 72 horas em relação à associação clorpirifós + cipermetrina + butóxido de piperonila + citronelal. Não foi constatada sobrevivência de nenhum juvenil infectivo nos grupos expostos à associação clorfenvinfós + diclorvós. A exposição ao clorfenvinfós resultou em percentual de sobrevivência inferior a 50% após 72 horas. O potencial de infectar lagartas de G. mellonella foi reduzido apenas no grupo tratado com o princípio ativo clorfenvinfós. Dessa forma, é possível concluir que o princípio ativo clorfenvinfós e a associação clorfenvinfós + diclorvós não foram compatíveis com H. AmazonensesRSC-5, causando redução no percentual de sobrevivência e infectividade dos juvenis desse nematoide. Os outros produtos foram compatíveis, não causando redução na infectividade do isolado testado.

The aim of this study was to assess the viability of Heterorhabditisamazonensis strain RSC-5 after exposure to different acaricides used for Rhipicephalusmicropluscontrol. Six treatment groups were formed, one for each product. Each group was composed of 75,000 nematodes in a 20 mL solution of different acaricides, at commercial concentration. The control group was formed by the same number of nematodes in 20 mL of distilled water. All the groups were kept in a climate-controlled chamber at 25°C. The percentage of survival and infectivity in Galleria mellonella caterpillars were determined 24 and 72 hours after the beginning of the experiment. The mortality of the caterpillars in the infectivity test was assessed 72 and 120 hours. After 24 hours of exposure, only the active ingredient deltamethrin did not significantly reduce the survival percentage of H. amazonensis RSC-5 (p > 0.05). The same was observed after 72 hours of exposure to the combination of chlorpyriphos + cypermethrin + piperonyl butoxide + citronellal. There was no survival of infective juveniles in the groups exposed to the combination of chlorphenvinphos + dichlorvos. The exposure to chlorphenvinphos for 72 hours resulted in 50% of mortality. The potential to infect G. mellonella caterpillars was only reduced in the group treated with the active ingredient chlorphenvinphos. Chlorphenvinphos and the combination of chlorphenvinphos + dichlorvos were not compatible with H. amazonensisRSC-5, causing a reduction in the survival and infectivity of juveniles of this nematode, while the other products were compatible, causing no reduction in the infectivity of this isolate.

Objective. Consumption of water may help promote health and prevent obesity in children by decreasing consumption of sugar-sweetened beverages. This study used evidence-based strategies to increase water consumption in Mexican-American and Mexican children. Materials and methods. In 2012, two schools in San Diego, USA and two other in Tlaltizapan, Mexico were recruited to Agua para Niños (Water for Kids), a program designed to promote water consumption among elementary grade students. Guided by operant psychology, the intervention focused on school and classroom activities to encourage water consumption. One control and one intervention school in each country were included. Results. Agua para Niños resulted in increases in observed water consumption and bottle possession among US and Mexican students. Teacher receptivity to the program was very positive in both countries. Conclusions. Agua para Niños yielded sufficiently positive behavioral changes to be used in a future fully randomized design, and to contribute to school nutrition policy changes.

Objetivo. Explorar cómo el consumo de agua proporciona salud y previene la obesidad en los niños al disminuir el consumo de bebidas endulzadas con azúcar, a partir del empleo de estrategias basadas en la evidencia para aumentar el consumo de agua en niños mexicanos y mexicano-estadounidenses. Material y métodos. En 2012, se eligieron dos escuelas en San Diego, EU y otras dos en Tlaltizapán, Morelos, México para implementar el programa Agua para Niños (Water for Kids), diseñado para promover el consumo de agua en los niños de nivel primaria. Bajo el enfoque de la psicología operante, la intervención se centró en las actividades escolares en general y dentro del aula para fomentar el consumo de agua. Resultados. Agua para Niños logró un aumento en el consumo de agua y la utilización personal de una botella con este líquido entre los estudiantes mexicano-estadounidenses y mexicanos. La receptividad del programa por parte de los maestros fue bastante positiva en ambos países. Conclusiones. Agua para Niños produjo cambios conductuales suficientemente positivos, lo que la hace una estrategia que puede utilizarse en futuros estudios aleatorizados que contribuyan a lograr cambios en las políticas escolares de nutrición.

Objective. The objective of this systematic literature review was to identify evidence-based strategies associated with effective healthcare interventions for prevention or treatment of childhood obesity in Latin America. Materials and methods. A systematic review of peer-reviewed, obesity-related interventions implemented in the healthcare setting was conducted. Inclusion criteria included: implementation in Latin America, aimed at overweight or obese children and evaluation of at least one obesity-related outcome (e.g., body mass index (BMI), z-score, weight, and waist circumference, and body fat). Results. Five interventions in the healthcare setting targeting obese children in Latin America were identified. All five studies showed significant changes in BMI, and the majority produced sufficient to large effect sizes through emphasizing physical activity and health eating. Conclusion. Despite the limited number of intervention studies that treat obesity in the healthcare setting, there is evidence that interventions in this setting can be effective in creating positive anthropometric changes in overweight and obese children.

Objetivo. El objetivo de esta revisión sistemática de la literatura fue identificar estrategias basadas en evidencia asociadas con intervenciones en salud efectivas para la prevención y el tratamiento de la obesidad infantil en Latinoamérica. Material y métodos. Se realizó una revisión sistemática por pares de intervenciones relacionadas con la obesidad, que fueron llevadas a cabo en clínicas de atención para la salud. Criterios de inclusión: implementadas en Latinoamérica, dirigidas a niños con obesidad y sobrepeso y evaluación de por lo menos un resultado relacionado con obesidad (ej. índice de masa corporal (IMC), puntaje Z, peso, circunferencia de cintura o grasa corporal). Resultados. Se identificaron cinco intervenciones dirigidas a niños obesos en clínicas de salud en Latinoamérica. Todas las intervenciones mostraron cambios significativos en IMC y la mayoría obtuvo un tamaño del efecto grande a través de la promoción de actividad física y alimentación saludable. Conclusión. A pesar del número limitado de estudios de intervención para tratar la obesidad en clínicas de salud, existe evidencia que las intervenciones en estos lugares pueden ser efectivas en alcanzar cambios antropométricos positivos en los niños con obesidad y sobrepeso.

Os carrapatos são susceptíveis à infecção por nematoides entomopatogênicos. Essa susceptibilidade diverge quanto às espécies de carrapato estudadas, à fase evolutiva, às espécies e estirpes dos nematoides e ao tempo ao qual os carrapatos ficam expostos a estes. O presente trabalho teve como objetivo avaliar os tempos de infecção in vitro de fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus pelo nematoide entomopatogênico Steinernema glaseri estirpe CCA, pela análise dos parâmetros biológicos do carrapato. Os resultados obtidos demonstraram que um período de duas horas de exposição foi suficiente para que fêmeas ingurgitadas de R. microplus fossem infectadas por S. glaseri CCA e que um período de exposição mínimo de 24h foi necessário para que houvesse infecção de fêmeas ingurgitadas de R. microplus por S. glaseri estirpe CCA, capaz de gerar, in vitro, eficácia no tratamento superior a 90%.

Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes species and strains and the time the ticks are exposed to them. Usually this period ranges from 24 to 72 hours. The aim of this study was to evaluate the infection times in vitro of engorged Rhipicephalus (Boophilus) microplus females by the entomopathogenic nematodes Steinernema glaseri CCA strain, by analysis of the ticks' biological parameters. The results show that a 2-hour exposure time was sufficient for the engorged R. microplus females to be infected by S. glaseri CCA, but that a minimum exposure time of 24 hours was necessary to generate treatment efficacy above 90%.

The majority of tobacco advertisement in Spain is directed at youth. This advertisement, carried out on several fronts, is particularly effective with young people. In the present work we analyze different advertising efforts involved in the ad campaign carried out by Fortuna-brand (a product of the company Tabacalera S.A., and sector leader of sales in Spain) in 1999 and 2000. In terms of their marketing strategy, we can conclude that Fortuna's principal commercial objective is presenting tobacco as intrinsically associated with being young. Both the indirect promotion of its products through activities and its commercials, are aimed towards developing the image that tobacco symbolizes the series of core values more appreciated by youth. Relevant legislation will have to be adapted to this reality in order to control specifically the manner in which publicity such as that promoted by Fortuna is directed to the population.

La mayor parte de la publicidad que sobre tabaco se emite actualmente en España va dirigida a la población joven. Esta publicidad resulta particularmente atractiva para este colectivo, al que se trata de llegar desde frentes muy diversos. En el presente trabajo se analizan las distintas actividades incluidas en la campaña publicitaria realizada por Fortuna (perteneciente a Tabacalera, SA y líder de ventas del sector en España) durante los años 1999 y 2000. El análisis de dicha publicidad permite concluir que la estrategia de Fortuna es presentar el tabaco como intrínsecamente unido con una serie de valores positivos atractivos a la juventud. Tanto la promoción indirecta de los productos de Fortuna como los anuncios de la marca intentan crear la imagen de que el tabaco simboliza los valores más apreciados por los jóvenes. La legislación al respecto debería adaptarse a esta realidad, a fin de controlar de manera más precisa los mensajes publicitarios que, como los de Fortuna, se dirigen a la población.
