Abstract: one of the most severe diseases in common bean (phaseolus vulgaris l.) is golden mosaic caused by bean golden mosaic virus (bgmv, genus begomovirus, family geminiviridae). this study aimed to evaluate the influence of different irrigation systems on the incidence and losses caused by bgmv in common bean. the experiment consisted of the evaluation of three irrigation systems (drip, sprinkler and micro sprinkler), installed as 225m2 strips in the experimental area of the federal university of alagoas, rio largo, al. each strip contained 12 plots of 1m2 each, with 20 plants per plot. the experiment was conducted over two seasons: october 2006 to january 2007 and october 2007 to january 2008. the incidence of golden mosaic was evaluated by visual inspection of symptomatic plants, and the asymptomatic plants were tested for the presence of begomoviruses by pcr. for yield evaluations, the weight of mature grains from all plants was quantified, and the average weight per plant in each plot was calculated. the results indicate that drip and sprinkler irrigation resulted in the highest (62.31%) and lowest (16.74%) incidence, respectively, of golden mosaic. there was no correlation between the incidence of golden mosaic and yield. however, healthy plants yielded three times more grain than diseased plants.

Abstract: the production of faba bean (phaseolus lunatus) is limited due to the occurrence of rhizoctonia canker, caused by the fungus rhizoctonia solani. in order to select materials with potential for use in faba beans breeding programs and/or disease integrated management, 72 genotypes were evaluated and also stability of the disease resistance in relation to different pathogen isolates, inoculum densities and soil type. the seeds were sown in soil infested with the pathogen by the addition of colonized substrate (rice grains). the evaluation of genotypes was done after 15 days, using a note scale to discriminate the genotypes into five reaction classes. none of the 72 genotypes showed immunity to r. solani and only four genotypes (f-42, f-49, f-53 and f-58) behaved as highly resistant. the reactions presented by these genotypes varied according to the r. solani isolate, inoculum density and soil used. the genotype f-58 showed more stable resistance to pathogen isolates and inoculum densities. the genotype f-53 showed resistance stability in soils collected in different locations, remaining highly resistant in all situations. the genotype f-58 did not show high resistance to only one tested soil. therefore, the genotypes f-58 and f-53 are promising sources of resistance to r. solani and should be indicated in areas infested by the pathogen.
Reproductive performance of the mite Brevipalpus phoenicis (Geijskes, 1939) on citrus and coffee, using life table parameters

Abstract: the flat-mite brevipalpus phoenicis (geijskes, 1939) (acari: tenuipalpidae) is considered important in citrus (citrus spp.) and coffee plants (coffea spp.) in brazil, and is known as the leprosis and coffee ring spot mite, as being a vector of the citrus leprosis rhabdovirus - citlv and coffee ring spot virus - corsv. the objective of this work is to find out about the reproductive success of b. phoenicis on citric fruits and coffee leaves by fertility life table parameters and its biology. the experiments were carried out in laboratory conditions at 25 ± 2 °c, 70 ± 10% of relative humidity and 14 h of photophase. the lengths of embryonic and post-embryonic periods were different due to the host where the mite was reared. b. phoenicis showed better development and higher survival and fecundity in citric fruits than coffee leaves. the intrinsic rate of the population increase (rm) was 0.128 and 0.090 - females/female/day on citric fruits and coffee leaves, respectively. the citric fruits were more appropriate for the development of b. phoenicis than coffee leaves.
Five Independents Variables Affecting Bullying: Neighborhood, Family, School, Gender-Age and Mass Media  [PDF]

Sociology Mind (SM) , 2013, DOI: 10.4236/sm.2013.34041

It is probably true to say that bullying is the psychosocial phenomenon which has attracted the most attention in academic circles over the last ten years. It affects approximately three to five percent of adolescents from twelve to eighteen years of age worldwide to a serious degree and up to twenty percent of this population to a lesser degree. The long and short term effects of bullying are considered to be extremely damaging. The importance of this phenomenon is that it may give rise to low self-esteem, anomie, depression, isolation, psychosomatic symptoms, failure at school and in extreme cases, it may result in suicide and future incidences of bullying in the workplace and within the home. As the number and the seriousness of incidents increases, many parents worry that the problem is spiralling out of control. In recent years, there has been a proliferation of publications on bullying, with an emphasis on how, when and where it occurs, but not on the factors which cause it. This meta-analysis studies the influence of five social environmental variables: neighborhood, family, school, gender-age and the mass media, considered on both an individual and interactional level, as their effects are often augmented when two or more variables are examined together. The concept “bullying” encompasses both individual and collective aggression and individual and collective victimization.

Ethnicity, Labor and Indigenous Populations in the Ecuadorian Amazon, 1822-2010  [PDF]
Robert Wasserstrom, Teodoro Bustamante
Advances in Anthropology (AA) , 2015, DOI: 10.4236/aa.2015.51001
Abstract: According to most recent research, Indians in Ecuador’s Amazonian region (the Oriente) lived outside of modern markets and political systems until around 40 years ago. But this view obscures the essential role of indigenous labor in earlier cycles of extractivism and exploitation. Beginning in the 18th century, lowland Quichua and other ethnic groups were defined as much by their place within long-distance economic networks as they were by their languages or cultures. Using newly discovered historical records and other sources, we can now reconstruct the ebb and flow of commodity booms in Amazonian Ecuador and their impact on indigenous populations.

Abstract: Objetivos. Desarrollar, aplicar y evaluar un modelo educativo de prevención primaria de enfermedades de transmisión sexual (ETS) y síndrome de inmunodeficiencia adquirida (sida) basado en los conocimientos, actitudes y prácticas (CAP) sexuales de los adolescentes y en sus percepciones y conductas al respecto, con el objetivo final de contribuir al desarrollo de herramientas educativas de prevención de las ETS y de la infección por virus de la inmunodeficiencia humana (VIH). Métodos. Se aplicó un modelo de prevención primaria de ETS y VIH/sida a escolares adolescentes (12 a 15 a os) de Santo Domingo de los Colorados, Ecuador. Se formaron dos grupos con características similares: el grupo de intervención (grupo I, n = 358) y el grupo de control (grupo C, n = 288). Las escuelas se seleccionaron por criterios de inclusión, y los adolescentes de cada escuela, al azar. Se aplicó una guía de discusión a 16 grupos focales; con esta información se elaboró una encuesta sobre conocimientos, actitudes y prácticas (CAP) que, después de su validación, fue aplicada a ambos grupos. En el grupo I se implementó un programa educativo de prevención dirigido a estudiantes y docentes. Ocho meses más tarde se aplicó una segunda encuesta CAP a los dos grupos. Las diferencias en los CAP antes y después de la intervención fueron evaluadas utilizando la prueba de la ji2. Resultados. No existieron diferencias significativas entre los dos grupos antes de la intervención, pero después de ella las diferencias fueron estadísticamente significativas (P = 0,012); se verificó un aumento de conocimientos sobre sexualidad y ETS/sida en el grupo I, aunque todavía no se ha evaluado la modificación de conductas a largo plazo. Conclusiones. Este estudio permitió validar un modelo multifactorial de prevención de ETS/sida adecuado a la realidad de los adolescentes, y sugiere la posibilidad de extrapolar la experiencia a escalas mayores en contextos similares a los de la población investigada.
