What the eyes can’t see: the future according to Monteiro Lobato

Over the last years, Monteiro Lobato has been rightfully accused by Brazilian and Latin American scholars of expressing racist and eugenic ideas in his body of work. In this article, we take a step further and add to this traditional portrait of his literary production an analysis of the impact of a new set of technological media during the first decades of the twentieth century on his writings. We discuss how these two main issues – i.e., technology and race – played out in Lobato’s historical representation of Brazil’s past and future and the influence that the United States could play in it. We show how a revisionary and racist version of the United States’ history and the ideal of an American technological prosperity in the 1920s inspired one of Lobato’s most contentious novels, the technological dystopia O Presidente Negro, ou O Choque das Raças, published in 1926.   &nbsp

AspectGrid: Aspect-Oriented Fault-Tolerance in Grid Platforms

Migrating traditional scientific applications to computational Grids requires programming tools that can help programmers update application behaviour to this kind of platforms. Computational Grids are particularly suited for long running scientific applications, but they are also more prone to faults than desktop machines. The AspectGrid framework aims to develop methodologies and tools that can help Grid-enable scientific applications, particularly focusing on techniques based on aspect-oriented programming. In this paper we present the aspect-oriented approach taken in the AspectGrid framework to address faults in computational Grids. In the proposed approach, scientific applications are enhanced with fault-tolerance capability by plugging additional modules. The proposed technique is portable across operating systems and minimises the changes required to base applications

Results Tres temas generales reflejan las representaciones de los participantes sobre los problemas mentales en el futuro - enfermedades mentales a edades avanzadas, polarización de la atención, y desafíos de la atención. La atención primaria en salud aparece como una estrategia importante para hacer frente a los obstáculos a la atención de la salud mental en la comunidad. No obstante, representacionces descalificadoras, estigmas y la organización de servicios constitutyen los retos principales al cuidado de la salud mental en la madurez. Conclusion Este artículo destaca la necesidad de hacer frente a los obstáculos culturales y organizativos para promover la calidad en la atención.Objective This study aims to explore medical students’ social representations of mental ill health in older adults. Method It comprises an exploratory and qualitative investigation based on the theory of social representations. Two focus groups with pre-clinical medics (group 1, N=4; group 2, N=4) and 10 individual interviews with clinical medical students were conducted. Thematic analysis at a latent level explored meanings and differences between groups. Results Three overarching themes reflect participants’ representations of mental health problems in later life – mental ill health in old age, polarisation of care, and challenges to care. Primary health care appears as an important strategy to overcome barriers to mental health care in the community. Nevertheless, disqualifying representations, stigma and organization of services constitute the main challenges to quality mental health care in later life. Conclusion This paper highlights the need to address cultural and organizational barriers to promote quality care

Checkpoint and run-time adaptation with pluggable parallelisation

Enabling applications for computational Grids requires new approaches to develop applications that can effectively cope with resource volatility. Applications must be resilient to resource faults, adapting the behaviour to available resources. This paper describes an approach to application-level adaptation that efficiently supports application-level checkpointing. The key of this work is the concept of pluggable parallelisation, which localises parallelisation issues into multiple modules that can be (un)plugged to match resource availability. This paper shows how pluggable parallelisation can be extended to effectively support checkpointing and run-time adaptation. We present the developed pluggable mechanism that helps the programmer to include checkpointing in the base (sequential). Based on these mechanisms and on previous work on pluggable parallelisation, our approach is able to automatically add support for checkpointing in parallel execution environments. Moreover, applications can adapt from a sequential execution to a multi-cluster configuration. Adaptation can be performed by checkpointing the application and restarting on a different mode or can be performed during run-time. Pluggable parallelisation intrinsically promotes the separation of software functionality from fault-tolerance and adaptation issues facilitating their analysis and evolution. The work presented in this paper reinforces this idea by showing the feasibility of the approach and performance benefits that can be achieved.(undefined

The rare richardsitas betsch (collembola, symphypleona, sminthuridae) : a new species from Australia with comments on the genus and on the sminthurinae

Richardsitas Betsch is a small genus of Sminthurinae with only two species described so far, both from Madagascar. It resembles other Sminthurinae with long antennae, especially Temeritas Richards. Here we provide the first record of Richardsitas from Australia, Richardsitas subferoleum sp. nov., which is similar to R. najtae Betsch and R. griveaudi Betsch in males’ large abdomen chaetotaxy and presence of tenent-hairs on tibiotarsi II–III, but lacks mucronal chaeta and has 28 segments on the fourth antennal segment plus a unique pair of sensilla on the second. We also provide an updated genus diagnosis to Richardsitas, a key to its species, a discussion of the affinities of Temeritas and Richardsitas to other Sminthurinae, and an updated key to this subfamily. © 2020 by the authors.

Optimizing survival outcomes with post-remission therapy in acute myeloid leukemia.

Optimization of post-remission therapies to maintain complete remission and prevent relapse is a major challenge in treating patients with acute myeloid leukemia (AML). Monitoring patients for measurable residual disease (MRD) is helpful to identify those at risk for relapse. Hypomethylating agents are being investigated as post-remission therapy. Identification of recurrent genetic alterations that drive disease progression has enabled the design of new, personalized approaches to therapy for patients with AML. Emerging data suggest that targeted post-remission therapy, alone or in combination with chemotherapy, may improve outcomes. Results of ongoing clinical trials will further define potential clinical benefits

AOmpLib: an aspect library for large-scale multi-core parallel programming

This paper introduces an aspect-oriented library aimed to support efficient execution of Java applications on multi-core systems. The library is coded in AspectJ and provides a set of parallel programming abstractions that mimics the OpenMP standard. The library supports the migration of sequential Java codes to multi-core machines with minor changes to the base code, intrinsically supports the sequential semantics of OpenMP and provides improved integration with object-oriented mechanisms. The aspect- oriented nature of library enables the encapsulation of parallelism-related code into well-defined modules. The approach makes the parallelisation and the maintenance of large-scale Java applications more manageable. Furthermore, the library can be used with plain Java annotations and can be easily extended with application- specific mechanisms in order to tune application performance. The library has a competitive performance, in comparison with traditional parallel programming in Java, and enhances programmability, since it allows an independent development of parallelism-related code.This work is funded by ERDF - European Regional Development Fund through the COMPETE Programme (operational programme for competitiveness) and by National Funds through the FCT - Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within projects FCOMP-01-0124-FEDER- 011413 and FCOMP-01-0124-FEDER-010152

Implementing an openMP-like standard with AspectJ

This paper presents an aspect-oriented library, coded in AspectJ, that aims to mimic the OpenMP standard for multicore program- ming in Java. Building the library on top of AspectJ intrinsically supports the sequential semantics of OpenMP. The library enables the use of parallelism related constructors in object-oriented sys- tems due to better compatibility with inheritance, making it more suitable to introduce parallelism into object-oriented frameworks. However, it requires more program refactoring than OpenMP di- rectives.This work is funded by ERDF - European Regional Development Fund through the COMPETE Programme (operational programme for competitiveness) and by National Funds through the FCT Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project FCOMP-01-0124FEDER-010152 and FCOMP-01-0124-FEDER-011413
