Component-aware Orchestration of Cloud-based Enterprise Applications, from TOSCA to Docker and Kubernetes

Enterprise IT is currently facing the challenge of coordinating the management of complex, multi-component applications across heterogeneous cloud platforms. Containers and container orchestrators provide a valuable solution to deploy multi-component applications over cloud platforms, by coupling the lifecycle of each application component to that of its hosting container. We hereby propose a solution for going beyond such a coupling, based on the OASIS standard TOSCA and on Docker. We indeed propose a novel approach for deploying multi-component applications on top of existing container orchestrators, which allows to manage each component independently from the container used to run it. We also present prototype tools implementing our approach, and we show how we effectively exploited them to carry out a concrete case study

Developing effective practice learning for tomorrow's social workers

This paper considers some of the changes in social work education in the UK, particularly focusing on practice learning in England. The changes and developments are briefly identified and examined in the context of what we know about practice learning. The paper presents some findings from a small scale qualitative study of key stakeholders involved in practice learning and education in social work and their perceptions of these anticipated changes, which are revisited at implementation. The implications for practice learning are discussed

ITS-rDNA phylogeny of Colletotrichum spp. causal agent of apple glomerella leaf spot.

Several diseases have affected apple production, among them there is Glomerella leaf spot (GLS) caused by Colletotrichum spp. The first report of this disease in apple was in plants nearby citrus orchards in São Paulo State, Brazil. The origin of this disease is still not clear, and studies based on the molecular phylogeny could relate the organisms evolutionarily and characterize possible mechanisms of divergent evolution. The amplification of 5.8S-ITS (Internal Transcribed Spacer) of rDNA of 51 pathogenic Colletotrichum spp. isolates from apples, pineapple guava and citrus produced one fragment of approximately 600 bases pairs (bp) for all the isolates analyzed. The amplified fragments were cleaved with restriction enzymes, and fragments from 90 to 500bp were obtained. The sequencing of this region allowed the generation of a phylogenetic tree, regardless of their hosts, and 5 isolated groups were obtained. From the "in silico" comparison, it was possible to verify a variation from 93 to 100% of similarity between the sequences studied and the Genbank data base. The causal agent of GLS is nearly related (clustered) to isolates of pineapple guava and to the citrus isolates used as control

Learning 3D Human Pose from Structure and Motion

3D human pose estimation from a single image is a challenging problem, especially for in-the-wild settings due to the lack of 3D annotated data. We propose two anatomically inspired loss functions and use them with a weakly-supervised learning framework to jointly learn from large-scale in-the-wild 2D and indoor/synthetic 3D data. We also present a simple temporal network that exploits temporal and structural cues present in predicted pose sequences to temporally harmonize the pose estimations. We carefully analyze the proposed contributions through loss surface visualizations and sensitivity analysis to facilitate deeper understanding of their working mechanism. Our complete pipeline improves the state-of-the-art by 11.8% and 12% on Human3.6M and MPI-INF-3DHP, respectively, and runs at 30 FPS on a commodity graphics card.Comment: ECCV 2018.

Simulating supervision: how do managers respond to a crisis?

Supervision is fundamental to child and family social work practice, in England as elsewhere, yet there is little research regarding what managers and social workers do when they meet to discuss the families they are working with. Recent years have seen a growing interest in the use of simulated clients and Objective Structured Clinical Exams to help develop and evaluate the abilities of social workers and students. This paper describes a study of 30 simulated supervision sessions between English social work managers and an actor playing the role of a student social worker in need of support. The simulation concerns a referral regarding an incident of domestic abuse. During the simulations, managers typically asked closed questions to obtain more information before providing solutions for the supervisee in the form of advice and direction. There was little evidence of emotional support for the social worker, nor empathy with the family. Managers typically acted as expert problem-solvers. The implications of this are discussed in relation to current theoretical models of supervision for child and family social work and in relation to how Children’s Services responds to domestic abuse

NASA: Neural Articulated Shape Approximation

Efficient representation of articulated objects such as human bodies is an important problem in computer vision and graphics. To efficiently simulate deformation, existing approaches represent 3D objects using polygonal meshes and deform them using skinning techniques. This paper introduces neural articulated shape approximation (NASA), an alternative framework that enables efficient representation of articulated deformable objects using neural indicator functions that are conditioned on pose. Occupancy testing using NASA is straightforward, circumventing the complexity of meshes and the issue of water-tightness. We demonstrate the effectiveness of NASA for 3D tracking applications, and discuss other potential extensions.Comment: ECCV 202

Characterization of \u3ci\u3eNeofabraea actinidiae\u3c/i\u3e and \u3ci\u3eN. brasiliensis\u3c/i\u3e as causal agents of apple bull’s-eye rot in southern Brazil

The causal agents of apple bull’s-eye rot in southern Brazil have recently been described as Neofabraea actinidiae and N. brasiliensis. Isolates of both species were evaluated for response of mycelial growth index (MGI) to different temperatures, enzyme production, mycelial growth inhibition and effective concentrations (EC50 and EC100) of the fungicides triflumizole, pyrimethanil and thiophanate methyl, as well as aggressiveness on fruits of ‘Fuji’ hybrid and ‘Pink Lady’. There was significantly lower mycelium growth in N. brasiliensis compared with N. actinidiae at all temperatures tested. Neither species grew at 3 and 32°C. There were minor differences in production of enzymes in the two species, with all N. brasiliensis isolates showing no production of pectolyase at pH 7. The lowest EC50 and EC100 values were observed with thiophanate methyl. In general, ‘Fuji’ fruits were more susceptible to Neofabraea infection and had larger lesions, while N. brasiliensis isolates showed greater aggressiveness on ‘Fuji’ hybrid and ‘Pink lady’ fruits compared with N. actinidiae. Dans le sud du Brésil, les agents causaux du chancre gloésporien de la pomme ont récemment été décrits comme étant Neofabraea actinidiae et N. brasiliensis. Des isolats des deux espèces ont été évalués en fonction de la réaction de l’indice de croissance mycélienne à différentes températures, de la production enzymatique, de l’inhibition de la croissance mycélienne et des concentrations efficaces (CE50 et CE100) des fongicides triflumizole, pyriméthanil et triophanate méthyle, ainsi qu’en fonction de leur agressivité à l’égard de la pomme hybride Fuji et de la Pink Lady. La croissance mycélienne chez N. brasiliensis était considérablement plus faible que chez N. actinidiae, et ce, à toutes les températures testées. Aucune espèce ne s’est développée à 3 ou à 32°C. Chez les deux espèces, il y a eu de petites différences quant à la production enzymatique, tous les isolats de N. brasiliensis n’affichant aucune production de pectolyase à pH 7. Les plus faibles valeurs de CE50 et de CE100 observées ont été celles du triophanate méthyle. Dans l’ensemble, les Fuji étaient plus sujettes à l’infection causée par Neofabraea et affichaient des lésions plus étendues, tandis que les isolats de N. brasiliensis étaient plus agressifs à l’égard de l’hybride Fuji et de la Pink Lady que ceux de N. actinidiae
