The potential for large-scale use of a sensitive real time reverse transcription polymerase chain reaction (RT-PCR) assay was evaluated for the detection of Tomato spotted wilt virus (TSWV) in single and bulked leaf samples by comparing its sensitivity with that of DAS-ELISA. Using total RNA extracted with RNeasy (R) or leaf soak methods, real time RT-PCR detected TSWV in all infected samples collected from 16 horticultural crop species (including flowers, herbs and vegetables), two arable crop species, and four weed species by both assays. In samples in which DAS-ELISA had previously detected TSWV, real time RT-PCR was effective at detecting it in leaf tissues of all 22 plant species tested at a wide range of concentrations. Bulk samples required more robust and extensive extraction methods with real time RT-PCR, but it generally detected one infected sample in 1000 uninfected ones. By contrast, ELISA was less sensitive when used to test bulked samples, once detecting up to I infected in 800 samples with pepper but never detecting more than I infected in 200 samples in tomato and lettuce. It was also less reliable than real time RT-PCR when used to test samples from parts of the leaf where the virus concentration was low. The genetic variability among Australian isolates of TSWV was small. Direct sequencing of a 587 bp region of the nucleoprotein gene (S RNA) of 29 isolates from diverse crops and geographical locations yielded a maximum of only 4.3% nucleotide sequence difference. Phylogenetic analysis revealed no obvious groupings of isolates according to geographic origin or host species. TSWV isolates, that break TSWV resistance genes in tomato or pepper did not differ significantly in the N gene region studied, indicating that a different region of the virus genome is responsible for this trait.

The effect of interspecific heterosis in crosses between Medicago sativa subsp. sativa and M. sativa subsp. falcata was assessed. Three sativa and 3 falcata plants were crossed in a diallel design. Progeny dry matter yield and natural plant height were assessed in a replicated field experiment at Gatton, Queensland. Yield data were analysed using the method of residual maximum likelihood (REML) and Griffing's model 1. There were significant differences between the reciprocal, general combining ability (GCA), and specific combining ability (SCA) effects. As expected, S-1 populations were lower yielding than their respective intraspecific cross and falcata x falcata crosses were significantly lower yielding than sativa x sativa crosses. Some of the interspecific crosses indicated substantial SCA effects, yielding at least as well as the best sativa x sativa crosses. We have demonstrated the potential usefulness of unselected M. sativa subsp. falcata as a heterotic group in the improvement of yield in northern Australian adapted lucerne material, and discuss how it could be incorporated into future breeding to overcome the yield stagnation currently being experienced in Australian programs.

Esta investigação empírica discute e analisa o trabalho docente do profissional do Ensino Médio, sua formação e desestruturação na sociedade contemporânea, procurando relacioná-la à própria crise da formação cultural em vigor. O objetivo principal é analisar as formas de adaptação e de resistência do professor perante as grandes mudanças e novas exigências para o educador do novo século iniciado no ano de 2000, com a chegada do novo milênio. A partir desse objetivo analisado, foi estudado como o professor compreende sua formação e carreira, focalizando as ações instauradas atualmente pela Secretaria do Estado da Educação de São Paulo, no período de 2000 a 2014, nas escolas de Ensino Médio do município de Barueri, confrontando com as regras propostas pela última LDB (Lei de Diretrizes e Bases) e legislação correlata também em âmbito estadual. A hipótese que rege esta investigação é a de que há inconsistências e incoerências na normatização na esfera executiva do sistema estadual de ensino. As Escolas Estaduais de Ensino Médio do município de Barueri (SP) serão o campo empírico desta pesquisa que se realizará em 2013 e 2014. A partir de informações obtidas por meio de análise documental e de respostas fornecidas por professores com questionários padronizados, objetivando caracterizar o perfil profissional do professor, confronta-lo com as exigências do sistema, identificar ações que regulam a sua seleção e explicitar sua manifestação sobre o impacto da má qualidade de sua formação no exercício da docência, fator que favorece o agravamento de forças conservadoras, cristalizadas em forma de práticas voltadas para a resolução de problemas do cotidiano escolar do Ensino Médio. Os estudos sobre cultura escolar, história da educação será apoiado Florestan Fernandes (1966), Otaíza de Oliveira Romanelli (1990), Helena Souza Patto (1999), Raquel Volpato Serbino (1998), Edgar Morin (2006), Guiomar Namo de Mello (2004), Dermeval Saviani (2003), Antônio Nóvoa (1995), José Mário P.

Brazilian pepper (Schinus terebinthifolius) is an exotic shrub or small tree that has become well established as an invasive and highly competitive species through much of southern Florida. Love vine (Cassytha filiformis), a native parasitic plant, was noted parasitizing Brazilian pepper, apparently affecting its health. The objective of this study was to investigate the nature of this parasitic interaction in southern Florida. Brazilian pepper populations were studied to determine whether parasitism by love vine may affect growth and reproduction. Anatomical studies of love vine parasitizing Brazilian pepper determined physical aspects of the parasitic interaction at the cell and tissue level. Physiological aspects of this interaction were investigated to help describe love vine resource acquisition as a parasite on host Brazilian pepper plants, and as an autotrophic plant. An investigation of ecological aspects of this parasitic interaction was done to determine whether physical or biological aspects of habitats may contribute to love vine parasitism on Brazilian pepper. These studies indicated that: (1) parasitism by love vine significantly decreased growth and reproduction of Brazilian pepper plants; (2) anatomical and physiological investigations indicated that love vine was primarily a xylem parasite on Brazilian pepper, but that some assimilated carbon nutrients may also be acquired from the host; (3) love vine is autotrophic (i.e., hemiparasitic), but is totally dependent on its host for necessary resources; (4) the occurrence of love vine parasitism on Brazilian pepper is mediated by physical characters of the biological community. ^

The climate of a school can be defined as the set of internal characteristics that distinguishes one school from another and influences the behavior of its members (Hoy & Hannum, 1997). Schools with a positive climate have been shown to positively impact students (Hoy, 1972). A principal’s leadership style influences the climate that, in turn, impacts student performance. ^ In this work, the researcher investigated Miami-Dade County Public Schools in order to determine if there was a relationship between instructional staff members’ perceptions of their school’s principals, a derivative of the district’s school climate studies, and their schools’ grades. ^ Eight School Climate Survey items were inter-correlated. The smallest intercorrelation was .83, which is still a large intercorrelation, and the largest intercorrelation was .96. Pearson’s correlation analysis (Healey, 2004) was run to determine the relationship between schools’ earned points and averaged survey responses. Survey items 8, 9, 12 and 13 had weak (less than .30) positive correlations to schools’ earned points. Survey items 7, 10, 11 and 14 had moderate (above .30) positive correlations to schools’ earned points. ^ The researcher created a composite variable (Pallant, 2007) from all the School Climate Survey responses. This composite variable, titled Principal Leadership Score, allowed the researcher to determine that approximately 9% of the variance in the points earned by schools in 2009 can be accounted for by how teachers in this study perceived the leadership of their principals. ^ This study’s findings of a moderate positive correlation between teachers’ perceptions of principal leadership and school performance supports earlier research linking school climate and school performance. Due to the fact that the leadership of the principal affects, either positively or negatively, the learning and working environment of students and teachers, it is recommended that principals use the eight School Climate Survey items examined within this study as guides (Pepper & Thomas, 2002). Through focusing on these survey items, principals may be propelled to self-identify their leadership strengths as well as leadership weaknesses.^

Schinus terebinthifolius Raddi (Schinus) is one of the most widely found woody exotic species in South Florida. This exotic is distributed across environments with different hydrologic regimes, from upland pine forests to the edges of sawgrass marshes and into saline mangrove forests. To determine if this invasive exotic had different physiological attributes compared to native species in a coastal habitat, we measured predawn xylem water potentials (Ψ), oxygen stable isotope signatures (δ18O), and sodium (Na+) and potassium (K+) contents of sap water from plants within: (1) a transition zone (between a mangrove forest and upland pineland) and (2) an upland pineland in Southwest Florida. Under dynamic salinity and hydrologic conditions, Ψ of Schinus appeared less subject to fluctuations caused by seasonality when compared with native species. Although stem water δ18O values could not be used to distinguish the depth of Schinus and native species' water uptake in the transition zone, Ψ and sap Na+/K+ patterns showed that Schinus was less of a salt excluder relative to the native upland species during the dry season. This exotic also exhibited Na+/K+ ratios similar to the mangrove species, indicating some salinity tolerance. In the upland pineland, Schinus water uptake patterns were not significantly different from those of native species. Differences between Schinus and native upland species, however, may provide this exotic an advantage over native species within mangrove transition zones.

Invasive plant species are major threats to the biodiversity and ecosystem stability. The purpose of this study is to understand the impacts of invasive plants on soil nutrient cycling and ecological functions. Soil samples were collected from rhizosphere and non-rhizosphere of both native and exotic plants from three genera, Lantana, Ficus and Schinus, at Tree Tops Park in South Florida, USA. Experimental results showed that the cultivable bacterial population in the soil under Brazilian pepper (invasive Schinus) was approximately ten times greater than all other plants. Also, Brazilian pepper lived under conditions of significantly lower available phosphorus but higher phosphatase activities than other sampled sites. Moreover, the respiration rates and soil macronutrients in rhizosphere soils of exotic plants were significantly higher than those of the natives (Phosphorus, p=0.034; Total Nitrogen, p=0.0067; Total Carbon, p=0.0243). Overall, the soil biogeochemical status under invasive plants was different from those of the natives.
