Selected AbstractsFormal support of stroke survivors and their informal carers in the community: a cohort studyHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 6 2008Chantal Simon PhD MSc MRCGP Abstract This cohort study, aims to explore formal care provision to stroke survivors and their informal carers in the community in the UK. An initial cohort of 105 cohabitant carers of first-time stroke patients was recruited while the stroke patient was in hospital. Structured face-to-face interviews were carried out with carers prior to discharge of the stroke patient home, at 6 weeks after discharge, and 15 months after stroke. Questionnaires included measures of psychological health (CIS-R), physical health (self-rated health), social well-being (relationship quality and Sarason's social support questionnaire), handicap of the stroke survivor (Oxford Handicap Scale) and formal community support (amount of formal support and carer satisfaction). Multiple services were involved with most survivor,carer pairs (mean 5.4; range 2,9; SD = 1.7), and 74% of carers were satisfied with formal support provided. Number of services decreased with time (5.5 versus 4.1, t = 4.201, d.f. = 52, P < 0.001, 95% confidence interval: 0.71,2.01) but not time allocated. Using stepwise linear regression, service provision early after discharge was predicted by: level of handicap, recruitment centre, carer self-rated health, number of informal supporters and other care commitments. Satisfaction was predicted by quality of informal support and activity restriction. Fifteen months after stroke, predictors of formal care were: level of handicap, quality of informal support and previous caring experience. Predictors of satisfaction were: quality of the relationship between the stroke survivor and carer, age and mood. Quality of services was good, but carers lacked information, had insufficient help and were not consulted enough. Carer distress is common, yet not currently a factor influencing support provision. Formal care provided adapts with time reflecting the importance of quality of support from friends and family rather than quantity of informal supporters. These factors should be taken into consideration when planning and providing formal support for stroke survivors and their carers. [source] A comparison of using Taverna and BPEL in building scientific workflows: the case of caGridCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 9 2010Wei Tan Abstract When the emergence of ,service-oriented science,' the need arises to orchestrate multiple services to facilitate scientific investigation,that is, to create ,science workflows.' We present here our findings in providing a workflow solution for the caGrid service-based grid infrastructure. We choose BPEL and Taverna as candidates, and compare their usability in the lifecycle of a scientific workflow, including workflow composition, execution, and result analysis. Our experience shows that BPEL as an imperative language offers a comprehensive set of modeling primitives for workflows of all flavors; whereas Taverna offers a dataflow model and a more compact set of primitives that facilitates dataflow modeling and pipelined execution. We hope that this comparison study not only helps researchers to select a language or tool that meets their specific needs, but also offers some insight into how a workflow language and tool can fulfill the requirement of the scientific community.

[source] SERVING FATHERS WHO LEAVE PRISONFAMILY COURT REVIEW, Issue 3 2003Jessica Pearson This article describes characteristics, service experiences, and outcomes for 350 ex-offenders with minor-aged children who were served at the John Inman Work and Family Center (WFC), a multiservice program offering assistance with employment, child support, and family reconnection. Following their visit to the WFC, fathers had higher rates of employment and child support payment. They also returned to prison at lower rates than the general offender population. Although the findings suggest that parents who leave prison benefit from a collaborative facility that offers multiple services, more rigorous research over longer periods of time is needed to reliably assess the effectiveness of reentry programs. [source] Ontological modelling of e-services to ensure appropriate mobile transactionsINTELLIGENT SYSTEMS IN ACCOUNTING, FINANCE & MANAGEMENT, Issue 3 2002Vagan TerziyanArticle first published online: 21 MAR 200 The main goal of this paper is to provide simple ontological support to mobile electronic commerce. The description of an ontology-driven Transaction Monitor (TM) for mobile business applications is considered. The approach is based on the assumption that the transaction management tool can be implemented in a mobile terminal, allowing integration of different distributed external e-services. We use the ontology-based framework for transaction management so that the TM will be able to manage transaction across multiple e-services and we consider management of distributed location-based services as an example of such ontology-based TM implementation. The core of the approach is very simple service ontologies. Ontologies should be ,placed' both in mobile terminals and in e-services. They define common multiple clients,multiple services standards and vocabularies for the use of the names, types, schemas, default values for parameters, atomic service actions with appropriate structure of action's input and output. In our implementation ontologies help to the TM to deal with multiple services during transactions and to simplify the appropriate user interface. Copyright © 2003 John Wiley & Sons, Ltd. [source] Service based CAC with QoS guarantee in mobile wireless cellular networksINTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 9 2005Robert G. Fry Abstract The increasing variety and complexity of traffic in today's mobile wireless networks means that there are more restrictions placed on a network in order to guarantee the individual requirements of the different traffic types and users. Call admission control (CAC) plays a vital role in achieving this. In this paper, we propose a CAC scheme for multiple service systems where the predicted call usage of each service is used to make the admission decision. Our scheme enables real-time traffic to be transmitted using shared bandwidth without quality of service (QoS) requirements being exceeded. This ensures that the utilization of the available wireless bandwidth is maximized. Information about the channel usage of each service is used to estimate the capacity of the cell in terms of the number of users that can achieve a certain bit error rate (BER). Priorities assigned to each service are used to allocate the network capacity. An expression for the handoff dropping probability is derived, and the maximum acceptance rate for each service that results in the estimated dropping probability not exceeding its QoS requirements is calculated. Each call is then accepted with equal probability throughout the duration of a control period. Achieved QoS during the previous control period is used to update the new call acceptance rates thus ensuring the dropping probability remains below the specified threshold. Simulations conducted in a wideband CDMA environment with conversational, streaming, interactive and background sources show that the proposed CAC can successfully meet the hard restraint on the dropping probability and guarantee the required BER for multiple services.

[source] Ontology-based speech act identification in a bilingual dialog system using partial pattern treesJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 5 2008Jui-Feng Yeh This article presents a bilingual ontology-based dialog system with multiple services. An ontology-alignment algorithm is proposed to integrate ontologies of different languages for cross-language applications. A domain-specific ontology is further extracted from the bilingual ontology using an island-driven algorithm and a domain corpus. This study extracts the semantic words/concepts using latent semantic analysis (LSA). Based on the extracted semantic words and the domain ontology, a partial pattern tree is constructed to model the speech act of a spoken utterance. The partial pattern tree is used to deal with the ill-formed sentence problem in a spoken-dialog system. Concept expansion based on domain ontology is also adopted to improve system performance. For performance evaluation, a medical dialog system with multiple services, including registration information, clinic information, and FAQ information, is implemented. Four performance measures were used separately for evaluation. The speech act identification rate was 86.2%. A task success rate of 77% was obtained. The contextual appropriateness of the system response was 78.5%. Finally, the rate for correct FAQ retrieval was 82%, an improvement of 15% over the keyword-based vector-space model. The results show the proposed ontology-based speech-act identification is effective for dialog management. [source] A bicriterion approach for routing problems in multimedia networksNETWORKS: AN INTERNATIONAL JOURNAL, Issue 4 2003João C. N. Clímaco Abstract Routing problems in communication networks supporting multiple services, namely, multimedia applications, involve the selection of paths satisfying multiple constraints (of a technical nature) and seeking simultaneously to "optimize" the associated metrics. Although traditional models in this area are single-objective, in many situations, it is important to consider different, eventually conflicting, objectives. In this paper, we consider a bicriterion model dedicated to calculating nondominated paths for specific traffic flows (associated with video services) in multiservice high-speed networks. The mathematical formulation of the problem and the bicriterion algorithmic approach developed for its resolution are presented together with computational tests regarding an application to video-traffic routing in a high-speed network. The algorithmic approach is an adaptation of recent work by Ernesto Martins and his collaborators, namely, the MPS algorithm. © 2003 Wiley Periodicals, Inc. [source] | ||||||||||
