The role and impact of female extension officers on the participation of women in export crop production in Papua New Guinea

The study investigated the roles and impact of female extension officers on the participation of smallholder women farmers in the production of Papua New Guinea’s major export commodity crops of cocoa, coffee and oil palm. The study found that female extension officers in the different commodity crops experienced different forms of gender bias, but when such biases were addressed women farmers were empowered to participate more fully in agricultural development

Early 2016/17 vaccine effectiveness estimates against influenza A(H3N2): I-MOVE multicentre case control studies at primary care and hospital levels in Europe

We measured early 2016/17 season influenza vaccine effectiveness (IVE) against influenza A(H3N2) in Europe using multicentre case control studies at primary care and hospital levels. IVE at primary care level was 44.1%, 46.9% and 23.4% among 0–14, 15–64 and ≥ 65 year-olds, and 25.7% in the influenza vaccination target group. At hospital level, IVE was 2.5%, 7.9% and 2.4% among ≥ 65, 65–79 and ≥ 80 year-olds. As in previous seasons, we observed suboptimal IVE against influenza A(H3N2)

The Effectiveness of a Program for Students with Severe EBD in Restrictive Classroom Settings

The education of students struggling with emotional and behavioral disorders (EBD) continues to be a serious and challenging problem facing educators and school systems in the 21st century. Legislation has been established by the Individuals Disabilities Act (IDEA) to include the provision of a free and appropriate public education (FAPE) to students identified as emotionally disturbed. However, many schools do not have adequate supports to meet the unique needs of children and adolescents with EBD. Scholars and practitioners have responded with efforts resulting in a collection of intervention strategies found to be helpful for supporting students suffering from emotional and behavioral challenges. However, much remains to be known regarding optimal programming for students with EBD in schools. The present study is a preliminary evaluation of the effectiveness of the Tiers of Intensive Educationally Responsive Services (TIERS) program. TIERS is a treatment package consisting of a combination of evidence-based practices designed to improve the academic, social-emotional, and behavioral outcomes of students with EBD. The purpose of this study was to 1) examine the effectiveness of the TIERS service delivery model for increasing positive classroom behaviors (PCBs) of students with severe EBD, and 2) to identify the degree to which implementation fidelity and grade level moderates the effectiveness of TIERS to affect their PCB. Results suggest that 1) students with severe EBD enrolled in a TIERS program show an increase in PCBs after a period of four months, 2) mean PCB scores are higher for programs implementing TIERS with higher fidelity when compared to programs implementing TIERS with partial fidelity but not programs implementing TIERS with little to no fidelity, and 3) there is no significant three-way interaction between fidelity of implementation of TIERS, grade level (elementary and middle school compared to high school), and time on PCB. Limitations of the study and implications for future research in the area of programming for students with EBD in restrictive school settings are discussed

Détection des potentiels d'action par la fluorescence calcique chez le poisson zèbre

L'utilisation de fluorofores sensibles au calcium permet de mesurer de manière non invasive l'activité des neurones. En effet, les potentiels d'actions font augmenter la concentration de calcium à l'intérieur d'une cellule, ce qui à son tour fait augmenter la fluorescence. Un dé important est de retrouver la séquence de potentiels d'actions à partir d'une mesure de fluorescence. Dans ce mémoire, nous verrons comment utiliser la fluorescence calcique pour déterminer une séquence de potentiels d'actions. Nous appliquons un algorithme basé sur l'algorithme de Viterbi et les chaînes de Markov à états cachés, développés par Deneux et al. À l'aide de cet algorithme, nous estimons les trains de potentiels d'actions ayant lieu dans un ensemble de neurones de poisson zèbres in vivo

Implementación del sistema de sostenimiento con cable bolting, en las labores de extracción en el nivel 1910–tajo 771, unidad minera Cerro Lindo – Ica, 2021

El presente estudio se desarrollará el ciclo de extracción de manera continua de los tajos, tomando en cuenta que a medida que se desarrolla la explotación se evidenciarán aberturas, estas aberturas son los tajos vacíos que han sido explotados, lo que conlleva a grandes desafíos en el sostenimiento del Cx 771. Para dicha implementación se tomó en cuenta la instalación del cable bolting mecanizadamente con el jumbo cableador cabolt, cuyo equipo realizara el ciclo completo: perforación, cableado e inyectado. El propósito de esta tesis es abordar la seguridad y fortificación de las ventanas de extracción y las intersecciones cercanas en el tajo 771 mediante el uso de cable bolting. El tipo de investigación será aplicativa descriptiva, porque se confrontará la teoría con la realidad, también porque se buscará una solución a un problema existente en la mina. La población tomada para la investigación es la Minera Cerro Lindo y la muestra estará constituida por el crucero Cx 771 que se ubica en el nivel 1910, y para su determinación se tomaron mediciones en 9 estaciones geomecánicas ubicadas en la zona 1 y zona 2 en el nivel 1910. Los resultados de esta investigación están relacionados con el diseño, densidad de números de cables a instalar en las ventanas de extracción, intersecciones y también obtener un análisis de estabilidad del tajo 771 Finalmente se propondrán unas recomendaciones para potenciar la instalación del cable bolting en el CX 771 y asimismo tomarlo como modelo para otros tajos en la mina Cerro lindo

Phylogenetic Signal, Root Morphology, Mycorrhizal Type, and Macroinvertebrate Exclusion: Exploring Wood Decomposition in Soils Conditioned by 13 Temperate Tree Species

Woodlands are pivotal to carbon stocks, but the process of cycling C is slow and may be most effective in the biodiverse root zone. How the root zone impacts plants has been widely examined over the past few decades, but the role of the root zone in decomposition is understudied. Here, we examined how mycorrhizal association and macroinvertebrate activity influences wood decomposition across diverse tree species. Within the root zone of six predominantly arbuscular mycorrhizal (AM) (Acer negundo, Acer saccharum, Prunus serotina, Juglans nigra, Sassafras albidum, and Liriodendron tulipfera) and seven predominantly ectomycorrhizal (EM) tree species (Carya glabra, Quercus alba, Quercus rubra, Betula alleghaniensis, Picea rubens, Pinus virginiana, and Pinus strobus), woody litter was buried for 13 months. Macroinvertebrate access to woody substrate was either prevented or not using 0.22 mm mesh in a common garden site in central Pennsylvania. Decomposition was assessed as proportionate mass loss, as explained by root diameter, phylogenetic signal, mycorrhizal type, canopy tree trait, or macroinvertebrate exclusion. Macroinvertebrate exclusion significantly increased wood decomposition by 5.9%, while mycorrhizal type did not affect wood decomposition, nor did canopy traits (i.e., broad leaves versus pine needles). Interestingly, there was a phylogenetic signal for wood decomposition. Local indicators for phylogenetic associations (LIPA) determined high values of sensitivity value in Pinus and Picea genera, while Carya, Juglans, Betula, and Prunus yielded low values of sensitivity. Phylogenetic signals went undetected for tree root morphology. Despite this, roots greater than 0.35 mm significantly increased woody litter decomposition by 8%. In conclusion, the findings of this study suggest trees with larger root diameters can accelerate C cycling, as can trees associated with certain phylogenetic clades. In addition, root zone macroinvertebrates can potentially limit woody C cycling, while mycorrhizal type does not play a significant role

Case registry systems for pandemic influenza A(H1N1)pdm09 in Europe: are there lessons for the future?

Countries across Europe developed a range of database systems to register pandemic influenza A(H1N1)pdm09 cases. Anecdotal reports indicate that some systems were not as useful as expected. This was a cross-sectional, semi-structured survey of health professionals who collected and reported pandemic influenza A(H1N1)pdm09 cases in 23 countries within the 27 European Union (EU) Member States plus Norway. We describe here the experiences of using pandemic case register systems developed before and during the pandemic, whether the systems were used as intended and, what problems, if any, were encountered. We conducted the survey to identify improvements that could be made to future pandemic case registers at national and EU level. Despite many inter-country differences, 17 respondents felt that a standardised case register template incorporating a limited number of simple standard variables specified in advance and agreed between the World Health Organization and the European Centre for Disease Prevention and Control could be useful. Intra- and inter-country working groups could facilitate information exchange, clearer system objectives and improved interoperability between systems
