Prevalence of burnout in a sample of Brazilian teachers

2011

Background and Objectives: Burnout is a psychological response to chronic work-related stress of an interpersonal and emotional nature. Brazilian law have already contemplated burnout syndrome as a mental and behavioural disorder related to work. The aim of this study was to identify the prevalence of burnout in a sample of Brazilian teachers. Methods: The sample was composed of 714 teachers from 8 schools in Porto Alegre and its metropolitan area (Brazil). The levels of burnout were evaluated by the Spanish Burnout Inventory, educational version (SBI-Ed). In addition, Psychosomatic disorders were estimated by the UNIPSICO subscale. Results: The percentage of participants who indicated high…

Using Cloud Computing to Implement a Security Overlay Network

2012

This article proposes and analyzes a general cloud-based security overlay network that can be used as a transparent overlay network to provide services such as intrusion detection systems, antivirus and antispam software, and distributed denial-of-service prevention. The authors analyze each of these in-cloud security services in terms of resiliency, effectiveness, performance, flexibility, control, and cost.

FederatedCloudSim

2014

Recent developments show that the standardization of cloud service descriptions and exchange leads the way for the rise of cloud federations. In these federations CSPs (cloud service providers) can use resources of other CSPs in the case of a lack of local resources or they can add remote services to their catalogue. Cloud federations again demand for cloud brokers which offer the resources and services of different CSPs transparently to the users. Research of cloud federations in the real world is very complex and expensive as distributed hard- and software scenarios are needed. Therefore we present FederatedCloudSim, a very flexible cloud simulation framework that can be used to simulate …

Self-establishing a Service Level Agreement within Autonomic Cloud Networking Environment

2014

International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). Several research works have been proposed for the SLA establishing in cloud computing, but not in cloud networking. In this paper, we propose an architecture for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and a …

Autonomic Brokerage Service for an End-to-End Cloud Networking Service Level Agreement

2014

8 pages; International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) assurance and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and multiple Cloud Service Providers (CSPs) in a cloud networking environment using brokerage service. We focus on Qo…

Adding semantics to cloud computing to enhance service discovery and access

2012

Cloud computing is a technological paradigm that permits to offer computing services over the Internet. This new service model is closely related to previous, well-known distributed computing initiatives such as Web services and grid computing. In the current socio-economic climate, the affordability of cloud computing has gained it popularity among today's innovations. Under these circumstances, more and more cloud services become available. Consequently, it is becoming more and more difficult for service consumers to find and access those cloud services that fulfill their requirements. In this work, a cloud computing ontology is proposed that facilitates a semantic identification, discove…

La co-creación de valor en hoteles desde la lógica dominante del servicio: Una aplicación a clientes con discapacidad

2015

Con esta tesis doctoral se ha desarrollado la aplicación de un marco teórico de co creación de valor entre los clientes con discapacidad y el personal de los establecimientos hoteleros desde la lógica dominante del servicio (LDS), el enfoque de marketing cuyo desarrollo conceptual se inició en 2004 (Vargo & Lusch, 2004) y, en la actualidad, se constata su creciente interés en la investigación de marketing (Bettencourt, Lusch & Vargo, 2014; Chandler & Lusch, 2015). A partir de los estudios e investigaciones sobre la LDS (,Vargo & Lusch, 2004,2008;Hunt, 2004; Lusch et al, 2007; Payne et al 2008; Grönroos, 2008,Ballantyne &Varey, 2008; García et al, 2010; Shaw et al 2011; Park & Vargo 2012,Fit…

Crowdboard: An Augmented Whiteboard to Support Large-Scale Co-Design

2013

Co-design efforts attempt to account for many diverse viewpoints. However, design teams lack support for meaningful real-time interaction with a large community of potential stakeholders. We present Crowdboard, a novel whiteboard system that enables many potential stakeholders to provide real-time input during early-stage design activities, such as concept mapping. Local design teams develop ideas on a standard whiteboard, which is augmented with annotations and comments from online participants. The system makes it possible for design teams to solicit real-time opinions and ideas from a community of people intrinsically motivated to shape the product/service.

CALYPSO: a new HF RADAR network to monitor sea surface currents in the Malta-Sicily channel (Mediterranean sea)

2016

Located in one of the main shipping lanes in the Mediterranean Sea, and in a strategic region for oil extraction platforms, the Malta-Sicily channel is exposed to significant oil spill risks. Shipping and extraction activities constitute a major threat for marine areas of relevant ecological value in the area, and impacts of oil spills on the local ecosystems and the economic activities, including tourism and fisheries, can be dramatic. Damages would be even more devastating for the Maltese archipelago, where marine resources represent important economic assets. Additionally, North Africa coastal areas are also under threat, due to their proximity to the Malta-Sicily Channel. Prevention and…
