AIMS Little has been reported on self-harm among the UK Armed Forces, partly due to the difficulties in recording self-harm, within an often-difficult-to-reach population. This study assesses the lifetime prevalence of attempted suicide and self-harm within currently serving and ex-service personnel of the UK Armed Forces. METHODS Telephone interviews were conducted with 821 personnel who had...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

This paper describes an approach to designing self-healing component for robust, concurrent and distributed software architecture. A self-healing component is able to detect object anomalies inside of the component, reconfigure inter-component and intra-components before and after repairing the sick object, repair it, and then test the healed object. For this, each self-healing component is str...

Wireless Sensor Networks (WSNs) can provide three types of basic services: sensing, processing and disseminating. A shortcoming of any of these services can disturb the network goals. However, failures are not exceptions in WSNs, since problems as energy exhaustion, communication range loss or physical damages are usual incidents. Considering the need of managing WSNs in an efficient manner, im...

it is dawn clear that empowered employees in public sector perform a critical role in their organizational service quality. by the same token, currently competitive advantages stem from employees’ high self-confidence and their commitment toward the goals rather than application of high technologies. this study summarizes twenty influencing factors on employees empowerment including information...

With the growing demand on Web Services, self-adaptation in the highly-dynamic environment is becoming a key capability of service-based systems. As a solution for Web services to provide added value and high QoS, combining self-* and policies allows reducing management complexity and effectively drives adaptation. Also, providers must participate in the self-adaptation process as they are awar...

Service Oriented Architecture (SOA) provides a new way of application development by using existing services. The required services are collected and loosely composed to meet the user’s specification, where the architecture of SOA is dynamic that is, it can change dynamically at run time to meet the new requirements. This paper proposes an architecture which has the capability to analyze the de...

In order to facilitate continuous and quick adaptation to the change of environment and use requirement, this paper presents a self-evolution method for the remote sensing information service chain to keep effective and robust of service chain with lesser modification, and to maximize all users’ utilization under concurrent user requirements. According to the driver forces of service chain chan...
