Cultural Responses To Pain In Uk Children Of Primary School Age: A Mixed-Methods Study., Pary M. Azize, Ruth Endacott, Allegra Cattani, Ann Humphreys Jan 2014

Cultural Responses To Pain In Uk Children Of Primary School Age: A Mixed-Methods Study., Pary M. Azize, Ruth Endacott, Allegra Cattani, Ann Humphreys

Pain-measurement tools are often criticized for not addressing the influence of culture and ethnicity on pain. This study examined how children who speak English as a primary or additional language discuss pain. Two methods were used in six focus group interviews with 34 children aged 4-7 years: (i) use of drawings from the Pediatric Pain Inventory to capture the language used by children to describe pain; and (ii) observation of the children's placing of pain drawings on red/amber/green paper to denote perceived severity of pain. The findings demonstrated that children with English as an additional language used less elaborate language …

ABSTRACTBackgroundCare of patients at the end‐of‐life (EOL) may be influenced by the experiences, attitudes and beliefs of nurses involved in their direct care.AimTo investigate South African critical care nurses' experiences and perceptions of EOL care.DesignCross‐sectional survey.MethodsSouth African critical care nurses completed a modified version of the ‘VENICE’ survey tool. Data were collected concerning: attitudes towards EOL care; involvement in EOL decision‐making; and beliefs about EOL practices.ResultsOf 149 surveys distributed, 100 were returned (response rate 67%). Seventy‐six percent stated that they had had direct involvement in EOL care of patients, but a minority (29%) had participated in EOL decision‐making processes. Whilst …

Genome indexing is the basis for many bioinformatics applications. Read mapping (sequence alignment) is one such application where the goal is to align millions of short reads against reference genome. Several tools are available for read mapping which rely on different indexing techniques to expedite the alignment process. However, many of these contemporary alignment programs are sequential, memory intensive and cannot be easily scaled for larger genomes. Suffix tree is one of the most widely used data structures for indexing strings (genomes). Building a scalable suffix-tree based tool is particularly challenging due to the difficulties involved in parallel construction of …


Impact Of Loss Synchronization On Reliable High Speed Networks: A Model Based Simulation, Suman Kumar, Lin Xue, Seung Jong Park Jan 2014

Impact Of Loss Synchronization On Reliable High Speed Networks: A Model Based Simulation, Suman Kumar, Lin Xue, Seung Jong Park

Computer Science Faculty Research & Creative Works

Contemporary nature of network evolution demands for simulation models which are flexible, scalable, and easily implementable. In this paper, we propose a fluid-based model for performance analysis of reliable high-speed networks. In particular, this paper aims to study the dynamic relationship between congestion control algorithms and queue management schemes, in order to develop a better understanding of the causal linkages between the two. We propose a loss synchronization module which is user configurable. We validate our model through simulations under controlled settings. Also, we present a performance analysis to provide insights into two important issues concerning 10 Gbps high speed …


Sensor Authentication In Collaborating Sensor Networks, Jake Bielefeldt, Sriram Chellappan Jan 2014

Sensor Authentication In Collaborating Sensor Networks, Jake Bielefeldt, Sriram Chellappan

Computer Science Faculty Research & Creative Works

In this paper, we address a new security problem in the realm of collaborating sensor networks. By collaborating sensor networks, we refer to the networks of sensor networks collaborating on a mission, with each sensor network is independently owned and operated by separate entities. Such networks are practical where a number of independent entities can deploy their own sensor networks in multi-national, commercial, and environmental scenarios, and some of these networks will integrate complementary functionalities for a mission. In the scenario, we address an authentication problem wherein the goal is for the Operator Oi of Sensor Network Si to correctly …


Secure K-Nearest Neighbor Query Over Encrypted Data In Outsourced Environments, Yousef Elmehdwi, Bharath K. Samanthula, Wei Jiang Jan 2014

Secure K-Nearest Neighbor Query Over Encrypted Data In Outsourced Environments, Yousef Elmehdwi, Bharath K. Samanthula, Wei Jiang

Computer Science Faculty Research & Creative Works

For the past decade, query processing on relational data has been studied extensively, and many theoretical and practical solutions to query processing have been proposed under various scenarios. With the recent popularity of cloud computing, users now have the opportunity to outsource their data as well as the data management tasks to the cloud. However, due to the rise of various privacy issues, sensitive data (e.g., medical records) need to be encrypted before outsourcing to the cloud. In addition, query processing tasks should be handled by the cloud; otherwise, there would be no point to outsource the data at the …

Many large programs operate on collection types. Extensive libraries are available in many programming languages, such as the C++ Standard Template Library, which make programming with collections convenient. Extending programming languages to provide collection queries as first-class constructs in the language would not only allow programmers to write queries explicitly in their programs but it would also allow compilers to leverage the wealth of experience available from the database domain to optimize such queries. This paper describes an approach to reduce the run time of programs involving explicit collection queries by performing run time query optimization that is effective for …


Qos Aware Geographic Opportunistic Routing In Wireless Sensor Networks, Long Cheng, Jianwei Niu, Jiannong Cao, Sajal K. Das, Yu Gu Jan 2014

Qos Aware Geographic Opportunistic Routing In Wireless Sensor Networks, Long Cheng, Jianwei Niu, Jiannong Cao, Sajal K. Das, Yu Gu

QoS routing is an important research issue in wireless sensor networks (WSNs), especially for mission-critical monitoring and surveillance systems which requires timely and reliable data delivery. Existing work exploits multipath routing to guarantee both reliability and delay QoS constraints in WSNs. However, the multipath routing approach suffers from a significant energy cost. In this work, we exploit the geographic opportunistic routing (GOR) for QoS provisioning with both end-to-end reliability and delay constraints in WSNs. Existing GOR protocols are not efficient for QoS provisioning in WSNs, in terms of the energy efficiency and computation delay at each hop. To improve the …
