Abstract

Retrospective assessment of individual exposure in occupational settings is often based on the association of individual work histories with quantitative and semi-quantitative exposure information. In the absence of exposure information, researchers have commonly used proxy variables, but with strong assumptions and some limitations. In the present work, we estimate the time-varying exposure-risk function associated with the outcomes of interest, taking into account functional regression models and individual work periods. The work was motivated by the analysis of a cohort of dock workers occupationally exposed to asbestos in Italy. We evaluated the potential of our proposal through a series of simulations. We then compared our approach with traditional methods that use exposure proxy variables. [ABSTRACT FROM AUTHOR]

Abstract

The evolution of interconnected systems and the evolving demands in service requirements have led to data centers integrating multiple heterogeneous technologies that must coexist. Consequently, the resource management and the security of the infrastructure are becoming more complex than in traditional scenarios. In this context, technologies such as Software-Defined Networking (SDN) or Network Function Virtualization (NFV) are being embraced as mechanisms that facilitate communication management. The integration of both technologies into a single framework, termed Software-Defined NFV (SDNFV) introduces a multitude of tools for managing the security of the data center's resources. This work delineates the primary characteristics of the evolution of these communication networks and their application to information security and communications within a data center. It presents an illustrative use case demonstrating the application of these next-generation technologies to detect and mitigate a security issue through virtualized network functions deployed in containers.

Abstract

In view of AI model production and training, the traditional script based physical server or cluster mode has problems such as training inference separated, insufficient resource utilization, difficult migration of computing environment, and lengthy training process. This paper proposed a platform architecture for deep learning model training, the architecture divided into four layers: data platform layer, computing platform layer, training suite layer, and management platform layer. Firstly, it proposed an integrated framework masks differences in network structures and optimized the graphs. Secondly, it researched an adaptive resource matching mechanism based on GPU state reduced communication costs. At the same time, it improved re- source utilization by providing a heuristic algorithm based label matching scheduling algorithm. Moreover, the establishment of tenant management and disaster recovery mechanisms ensured the safety and reliability of the system platform. Finally, it established the validation of the usability, safety, reliability, and scalability through the simulation platform. Through the construction of deep learning platform, it will accelerate the implementation of AI production and promote the prosperity and development of AI technology and ecology.

Abstract

Objectives Scotland has an established Trusted Research Environment (TREs) through the Scottish Safe Haven Network. These Safe Havens traditionally service structured datasets, however, researchers increasingly require access to large multi-modal linked datasets that include medical imaging. We therefore introduced an equivalent to access anonymised NHS images and reports. Approach A pan-Scotland collaboration of 15 partners from industry, NHS, and academia, collaborated to design and deploy a Safe Haven equivalent for SMEs and researchers interested in accessing anonymised NHS imaging and reports to allow them to develop, test, and validate AI algorithms for greater patient benefit. Two Safe Haven sites, worked with a leading medical software research and development team, to deliver a secure analytical platform for the research and development of AI for medical applications. Results The Safe Haven Artificial Platform (SHAIP) is designed to support development of sophisticated AI components and has been used by several SME’s to undertake exemplar projects in stroke, breast screening, and x-ray interpretation for limb fracture and chest. These researchers were supported by the Safe Haven’s governance processes. SHAIP became the first research environment to be directly linked to the Scottish National PACS archive. Access was provided to project specific deidentified images using ‘Hidden in plain sight’; a privacy and data-structure preserving technique. The researchers were able to upload virtual-machines, or ‘dockers’, to bring their toolsets to their research workspaces. An annotation capability was provided to support ground-truth development for machine learning. Conclusion The project has shown we can pull large scale medical images and reports into a TRE in such a way NHS Boards are reassured by our methods, creating a safe analytical platform for AI development that will benefit patient care by providing faster, cheaper and more accurate solutions.

13. No dockers, no empire. The labour question at Dakar during World War I.

Author

Castillo Hidalgo, Daniel

Abstract

The Great War had a major impact on port activity at Dakar in Senegal. It increased bunkering and pushed up demand for daily labourers to provide an adequate service to the allied navies. This article analyses the changes in labour organization in the port during World War I. Based on archival sources held in the National Archives of Senegal, this study explores the ways in which the colonial administration tried to manage labour shortages on the docks. This research provides evidence of the institutional shifts in the colonial regime, where coercion strategies evolved into compensatory incentives to attract African workers. The vital military and economic roles played by Dakar as the gateway to French West Africa also explains the importance of institutional shift during the construction of colonial economic and political hegemony.

Abstract

The present work examines the case of a country, Chile, which often considered as a "laboratory of neo-liberalism". It centers round a recent experiment in union revitalisation, namely the creation and development of the "Chilean Harbours Union". I seek to trace the slow incubation of an exceptional trade union experiment in Chilean harbours. The ambition of this work is to bring to light the establishment and deployment, as well as the strengths and weaknesses, of a major trade union, that of the dockers, constrained by the authoritarian legal framework of an "advanced" neo-liberal context in which very precarious working conditions prevail. Beyond the Chilean case, the essay partakes of a wider debate on the origins of workers' resistance in countries of the global South, while also proposing a reflection on the dynamics of union regeneration and politicisation of work and workers.

Abstract

Online video broadcasting platforms are distributed, complex, cloud oriented, scalable, micro-service-based systems that are intended to provide over-the-top and live content to audience in scattered geographic locations. Due to the nature of cloud VM hosting costs, the subscribers are usually served under limited resources in order to minimize delivery budget. However, operations including transcoding require high-computational capacity and any disturbance in supplying requested demand might result in quality of experience (QoE) deterioration. For any online delivery deployment, understanding user's QoE plays a crucial role for rebalancing cloud resources. In this paper, a methodology for estimating QoE is provided for a scalable cloud-based online video platform. The model will provide an adeptness guideline regarding limited cloud resources and relate computational capacity, memory, transcoding and throughput capability, and finally latency competence of the cloud service to QoE. Scalability and efficiency of the system are optimized through reckoning sufficient number of VMs and containers to satisfy the user requests even on peak demand durations with minimum number of VMs. Both horizontal and vertical scaling strategies (including VM migration) are modeled to cover up availability and reliability of intermediate and edge content delivery network cache nodes.

Abstract

Scientific reproducibility is essential for the advancement of science. It allows the results of previous studies to be reproduced, validates their conclusions and develops new contributions based on previous research. Nowadays, more and more authors consider that the ultimate product of academic research is the scientific manuscript, together with all the necessary elements (i.e., code and data) so that others can reproduce the results. However, there are numerous difficulties for some studies to be reproduced easily (i.e., biased results, the pressure to publish, and proprietary data). In this context, we explain our experience in an attempt to improve the reproducibility of a GIScience project. According to our project needs, we evaluated a list of practices, standards and tools that may facilitate open and reproducible research in the geospatial domain, contextualising them on Peng’s reproducibility spectrum. Among these resources, we focused on containerisation technologies and performed a shallow review to reflect on the level of adoption of these technologies in combination with OSGeo software. Finally, containerisation technologies proved to enhance the reproducibility and we used UML diagrams to describe representative work-flows deployed in our GIScience project.

Abstract

The objective of this project is to study the open source tools that an operations team, following a SecDevOps methodology, should implement in its development infrastructure, to increase security. The project is based on a simple application that did not follow best security practices, and to which an infrastructure has been built around it, to solve this situation. The idea arises from the concern that, in a context of global digitalization, where in many cases, security mechanisms have not been applied in the best possible way, certain technologies and best practices must be applied to increase the level of security in the applications. The work is based on a microservices architecture, using containers to implement the applications, obtaining efficient, secure and scalable systems. In addition, a single sign on (SSO) authentication system has been added through OpenID Connect, a container monitoring system, a log centralization system, code scanners and container scanners, among others. The project allows to see the change that the application has undergone during the course of this process and concludes with an assessment of the operation of each of the tools used., El objetivo de este proyecto es estudiar las herramientas open source que un equipo de operaciones, siguiendo una metodología SecDevOps, debería implementar en su infraestructura de desarrollo, para incrementar la seguridad.

Abstract

Container shipping has constituted a revolution in trade on a planetary scale. Ports have had to change their infrastructures in order to incorporate the requisite technology, which has modified the historical trade networks around the World. The port of Las Palmas (Canary Islands) adapted its infrastructures and its institutional environment in order to develop the container activity that was added to its historical functions as scale port. The main aim of this paper is to explore the changes in port labour organization through the progressive implementation of container activities in Las Palmas. Port activity indicators, regulation, port infrastructures and labour relationships will be analysed with a view to presenting an overall perspective of the changes that have taken place in dock labour since the 1960s.

Abstract

This study examines the prominent 2013 Yantian dock strike in China and analyses the main factors contributing to the dockers’ successful campaign. It finds that the dockers’ capacity to take strike action mainly derives from their bargaining power, including structural power such as workplace bargaining power and logistical power, and their institutional power such as workers’ sense of moral power. More importantly, the event shows that the extent of dockworkers’ resistance, workplace union reform, and employers’ response were shaped by the globalisation of production in China’s seaport industry and the transformation of political economy in East Asia.

Abstract

As the 20th anniversary of the 1995–1998 Liverpool Dockers’ Strike approaches, this case of industrial action should not be dismissed as a reminder of yet another nail in the coffin of organised labour. Rather, this event needs to be viewed more optimistically in hindsight as a symbol that working-class consciousness and systems of solidarity had not vanished entirely from Britain after the crushing collapse of domestic manufacturing and the fall of the miners in 1985. Indeed, the Liverpool dockers invented a fresh campaign of industrial action at this time, led more from the ‘bottom-up’ than most other labour protests in the past. Fuelled by a cognisant awareness of both community and workplace experience within the context of popular historical memory, this industrial action played significant roles in reconfiguring and adapting solidarity in this new era of rentier, global capitalism. It is appropriate we recall working-class militancy in a city whose own historical narrative is often described as ‘exceptional’ when one reflects upon Liverpool’s long entrenched culture of opposition.

Abstract

[ES] En los últimos años, el campo de la inteligencia artificial ha sufrido una tremenda explosión debido principalmente a dos grandes factores. En primer lugar, el proceso de digitalización llevado a cabo durante las últimas décadas ha posibilitado obtener grandes cantidades de datos (ya sea dato estructurado, señal, imagen, vídeo, etc.) dando pie al desarrollo de algoritmos de machine learning que permiten generar modelos de conocimiento a partir del dato. Para que estas ingentes cantidades de datos puedan ser analizadas en busca de patrones característicos que definan cierta tarea, se precisa de un potente hardware que permita entrenar redes neuronales profundas. En este sentido, el segundo factor que ha posibilitado la explosión de la IA ha sido el gran crecimiento en el campo de la aceleración computacional por hardware gráfico mediante GPUs. En el contexto detallado anteriormente, el grupo de investigación CVBLab de la Universitat Politècnica de València dispone de una infraestructura propia de inteligencia artificial. El actor principal de esta infraestructura de inteligencia artificial es el sistema NVIDIA DGX A100. Dicha máquina está compuesta por 8x NVIDIA A100 Tensor Core GPUs ofreciendo 5 petaFLOPS de potencia de cálculo y 320GB de memoria RAM. Adicionalmente, CVBLab dispone de cuatro equipos Intel i7 @4.20GHz con 32GB de RAM y (2x) tarjetas gráficas NVIDIA Titan XP y dos equipos Intel i7 @4.20GHz con 32GB de RAM y (2x) tarjetas gráficas NVIDIA Titan V en cada máquina. El presente TFG tiene como objetivo la implementación de protocolos para la administración inteligente de recursos en un clúster GPU de altas prestaciones mediante la librería de gestión de colas de tarea SLURM y el uso de Dockers. Adicionalmente, el alumno se adentrará en el campo de la inteligencia artificial, generando tareas básicas con las que poder evaluar el correcto funcionamiento del protocolo implementado.

Abstract

In light of a series of innovative and spectacular transnational and domestic campaigns by port workers in advanced capitalist countries in the 1990s, this paper argues against a variant of the ‘race to the bottom’ thesis that holds little hope for worker resistance under conditions of assumed state weakening and capital globalisation or for the development of transnational strategies. Using a process tracing technique across horizontal (transnational) and vertical (domestic) axes of contention, and focussing specifically on the process of coalition building, evidence from the Liverpool and Australian campaigns by dockers under threat indicates the salience of both arenas of contention, but with greater importance to outcome resting on domestic level coalitional capacity.

Abstract

Les mémoires de Charles Marck témoignent, avec une belle fraîcheur, d’une existence ouvrière et de pratiques militantes aux grandes heures du syndicalisme révolutionnaire. À la rareté de tels récits s’ajoute la singularité d’un itinéraire qui mena l’auteur des quais du Havre au sommet de la CGT., Charles Marck's memoirs bear witness, with great freshness, to a working-class existence and militant practices in the heyday of revolutionary unionism. In addition to the rarity of such accounts, there is the singularity of an itinerary that led the author from the quays of Le Havre to the top of the CGT.

Abstract

The article presents a case study on the construction of memories in oral history and how the positions of the various actors in the narrative process have affected the historical construction of the drunken docker. It is argued that the representation of port workers in a society is dominated by its association with excessive alcohol consumption. It is emphasized that oral history is at the same level as other sources.

Abstract

Cette recherche s’intéresse à un pays souvent considéré comme « laboratoire du néolibéralisme », le Chili. Il est centré sur une expérience récente de revitalisation syndicale : la création et le développement de « l’Union portuaire du Chili ». Notre investigation décrit la lente incubation d’une expérience syndicale exceptionnelle dans les ports chiliens : il s’agit de présenter la constitution, le déploiement, la force, les faiblesses et les limites d’un pouvoir syndical stratégique, celui des dockers. Un processus qui s’insère dans un contexte néolibéral « avancé » et qui est marqué par un cadre légal autoritaire et la grande précarité des conditions de travail des salariés mobilisés. Au-delà du cas chilien, cet opus participe d’une discussion plus générale sur les ressorts des (in)soumissions ouvrières dans les pays du Sud, tout en proposant une réflexion sur les dynamiques de revitalisation syndicale et de politisation au/du travail. The present work examines the case of a country, Chile, which often considered as a "laboratory of neo-liberalism". It centers round a recent experiment in union revitalisation, namely the creation and development of the "Chilean Harbours Union". I seek to trace the slow incubation of an exceptional trade union experiment in Chilean harbours. The ambition of this work is to bring to light the establishment and deployment, as well as the strengths and weaknesses, of a major trade union, that of the dockers, constrained by the authoritarian legal framework of an "advanced" neo-liberal context in which very precarious working conditions prevail. Beyond the Chilean case, the essay partakes of a wider debate on the origins of workers' resistance in countries of the global South, while also proposing a reflection on the dynamics of union regeneration and politicisation of work and workers. Esta investigación se centra en un país considerado, a menudo, como un "laboratorio del neoliberalismo"; Chile. Se interesa en una experiencia reciente de revitalización sindical: la creación y desarrollo de la "Unión Portuaria de Chile". Nuestra investigación describe la lenta incubación de una experiencia sindical excepcional en los puertos chilenos: se trata de presentar la constitución, el despliegue, la fuerza, debilidades y límites de un poder sindical estratégico, el de los estibadores. Este proceso se inscribe en un contexto neoliberal "avanzado" marcado por un marco jurídico autoritario y por la gran precariedad de las condiciones de trabajo de los asalariados movilizados. Más allá del caso chileno, este opus forma parte de una discusión más general sobre los resortes de las (in)sumisiones obreras en los países del Sur, al mismo tiempo que propone una reflexión sobre las dinámicas de revitalización sindical y de politización en y del trabajo.

Abstract

Scientific reproducibility is essential for the advancement of science. It allows the results of previous studies to be reproduced, validates their conclusions and develops new contributions based on previous research. Nowadays, more and more authors consider that the ultimate product of academic research is the scientific manuscript, together with all the necessary elements (i.e., code and data) so that others can reproduce the results. However, there are numerous difficulties for some studies to be reproduced easily (i.e., biased results, the pressure to publish, and proprietary data). In this context, we explain our experience in an attempt to improve the reproducibility of a GIScience project. According to our project needs, we evaluated a list of practices, standards and tools that may facilitate open and reproducible research in the geospatial domain, contextualising them on Peng’s reproducibility spectrum. Among these resources, we focused on containerisation technologies and performed a shallow review to reflect on the level of adoption of these technologies in combination with OSGeo software. Finally, containerisation technologies proved to enhance the reproducibility and we used UML diagrams to describe representative work-flows deployed in our GIScience project.

42. Intersecting arcs of mobilisation: The transnational trajectories of Egyptian dockers’ unions.

Author

Anderson, Jeremy

Subjects
*MASS mobilization, *EGYPTIANS, *LABOR movement
Abstract

This commentary explores the development of Egypt’s dockers’ unions since February 2011 in terms of two interlinked trajectories. On the one hand, the Egyptian revolution has provided the primary impetus for dockers’ industrial activism, as, like many other workers throughout Egypt, they have taken advantage of the political space suddenly opened up. However, although the Egyptian revolution may seem the most obvious driving force behind the growth of unions on the country’s docks, these advances also conform to a regional pattern. Since 2007 a campaign by the International Transport Workers’ Federation (ITF) has seen new unions formed and collective bargaining rights won in many ports across the region, including in Bahrain, Jordan and Morocco. It is argued that the technical and industrial resources made available through the ITF’s activities and networks have, therefore, played an important role. The uncertain political environment in Egypt, however, threatens to stunt both the growth of independent unions, and curtail the support they receive from the international labour movement.

Abstract

Online video broadcasting platforms are distributed, complex, cloud oriented, scalable, micro-service-based systems that are intended to provide over-the-top and live content to audience in scattered geographic locations. Due to the nature of cloud VM hosting costs, the subscribers are usually served under limited resources in order to minimize delivery budget. However, operations including transcoding require high-computational capacity and any disturbance in supplying requested demand might result in quality of experience (QoE) deterioration. For any online delivery deployment, understanding user’s QoE plays a crucial role for rebalancing cloud resources. In this paper, a methodology for estimating QoE is provided for a scalable cloud-based online video platform. The model will provide an adeptness guideline regarding limited cloud resources and relate computational capacity, memory, transcoding and throughput capability, and finally latency competence of the cloud service to QoE. Scalability and efficiency of the system are optimized through reckoning sufficient number of VMs and containers to satisfy the user requests even on peak demand durations with minimum number of VMs. Both horizontal and vertical scaling strategies (including VM migration) are modeled to cover up availability and reliability of intermediate and edge content delivery network cache nodes.

Abstract

Objectives. Diesel exhaust particles (DEPs) containing polycyclic aromatic hydrocarbons stimulate the formation of IgE in humans following single and acute exposure. The aim of the present study was to ascertain whether long-standing occupational exposure to DEPs carries a risk of enhanced serum IgE, and of rhinitis or asthma. Methods. In this cross-sectional study, findings in 76 dockers were compared with those in 63 reference subjects. Among the dockers, drivers and laborers were exposed to diesel emission from forklifts or trucks in the ship-holds, where benzopyrene levels averaged 4.9 ng/m3. Serum IgE levels were measured by the UNICAP method. Atopy, an evident source of high IgE levels, was assessed by the Phadiatop test. The subjects' clinical and occupational histories were collected. Interval variables were analyzed with Student's t- and Levene's F-tests. The odds ratio (OR) with the 95% confidence interval (CI) was obtained by the exact method at univariate and multivariate (logistic regression) analysis. Results. In view of the large difference in serum IgE (P=0.00001) and the prevalence of respiratory diseases (P=0.009) between atopic and non-atopic subjects, we analyzed their data separately. For non-atopic subjects, the risk of presenting high IgE was significantly higher (OR=11.4; CI=1.44–526; P=0.013) and the risk of respiratory disease was significantly lower (OR=0.09; CI=0.00–0.73; P=0.016) in drivers and laborers as a whole than in the reference subjects. None of the ORs was significant among atopic individuals. Conclusions. In non-atopic dockers, long-standing exposure to DEPs at concentrations similar to those in heavily polluted cities increased serum IgE levels but not the incidence of rhinitis or asthma.

Abstract

While many studies have been focusing on reducing the time to manipulate Virtual Machine/Container images in order to optimize provisioning operations in a Cloud infrastructure, only a few studies have considered the time required to boot these systems. Some previous researches showed that the whole boot process can last from a few seconds to few minutes depending on co-located workloads and the number of concurrent deployed machines. In this paper, we discuss a large experimental campaign that allows us to understand in more details the boot duration of both virtualization techniques under various storage devices and resources contentions. Particularly, we analyzed thoroughly the boot time of VMs, Dockers on top of bare-metal servers, and Dockers inside VMs, which is a current trend of public Cloud Computing such as Amazon Web Services or Google Cloud. We developed a methodology that enables us to perform fully-automatized and reproducible experimental campaigns on a scientific testbed. Thanks to this methodology, we conducted more than 14.400 experiments on Grid’5000 testbed for a bit more than 500 hours.

Abstract

While many studies have been focusing on reducing the time to manipulate Virtual Machine/Container images in order to optimize provisioning operations in a Cloud infrastructure, only a few studies have considered the time required to boot these systems. Some previous researches showed that the whole boot process can last from a few seconds to few minutes depending on co-located workloads and the number of concurrent deployed machines. In this paper, we discuss a large experimental campaign that allows us to understand in more details the boot duration of both virtualization techniques under various storage devices and resources contentions. Particularly, we analyzed thoroughly the boot time of VMs, Dockers on top of bare-metal servers, and Dockers inside VMs, which is a current trend of public Cloud Computing such as Amazon Web Services or Google Cloud. We developed a methodology that enables us to perform fully-automatized and reproducible experimental campaigns on a scientific testbed. Thanks to this methodology, we conducted more than 14.400 experiments on Grid’5000 testbed for a bit more than 500 hours. The results we collected provide an important information related to the boot time behavior of these two virtualization technologies. Although containers boot much faster than VMs, both containers and VMs boot time are impacted by the co-workloads on the same compute node.; Si de nombreuses études se sont concentrées sur la réduction du temps nécessaire pour manipuler les images de machines virtuelles/conteneurs afin d’optimiser les opérations de provisionnement dans une infrastructure Cloud, seules quelques études ont examiné le temps requis pour le démarage de ces systèmes.
