     A CONSOLIDATED LEARNING ANALYSIS OF A STUDENT NURSE’S CLINICAL EXPERIENCE WITH A HIGH SCHOOL STUDENT WHO IS DEAF By: Sally Chung , Student Nurse, 4th year [email protected]  and Tracey Clancy, RN, MN, Nursing Practice Instructor [email protected], University of Calgary, Faculty of Nursing, Calgary, Alberta T2N 1N4 , Canada ABSTRACTBackground: This paper was developed during the first author’s Nursing 285 theory course. It is a foundational course with the intent of helping novice nursing students begin to develop an understanding of nursing as a profession and as a discipline.Aim: The purpose of this consolidation of learning assignment offered students an opportunity to reflect upon and articulate salient aspects from their experiential learning and to further explore their growing understanding through bridging theory to practice and expressing how this transformational learning informs who they are becoming as a registered nurse. The experience described in this reflective paper occurred during my first community health placement in the fall of 2011. Placed at a high school setting in Western Canada, I worked with a group of students with cognitive disabilities, some of whom were deaf as well. As defined by the Canadian Association for the Deaf (CAD, 2014), a person is recognized as medically/audiologically deaf when that person has “little to no functional hearing and depends upon visual rather than auditory communication.”Action Plan: When working with a particular student at this high school—we will refer to her as Lisa (pseudonym)—I found that Lisa had been born deaf.  Knowing that her strengths lay in sign language, I sought the help of her teacher and sign language aides (websites with translators and a sign language book) to better facilitate my teachings and improve our rapport.Discussion: The themes discussed in this paper are: critical thinking, self-regulation, adapting to changes when in practice, and the complexity of the nursing role.Conclusion: The complexity of the nursing role is a primary theme learned as a result of this experience in that nurses may oftentimes find themselves facing sudden or unexpected client status changes. The nurse needs to adapt to care for that client safely and effectively, thinking critically of priorities and what resources are available at the nurse’s disposal.Keywords: Reflective Learning for Nursing Students; Nursing Care; Persons who are dea

    Privacy-Preserving Outsourcing of Large-Scale Nonlinear Programming to the Cloud

    The increasing massive data generated by various sources has given birth to big data analytics. Solving large-scale nonlinear programming problems (NLPs) is one important big data analytics task that has applications in many domains such as transport and logistics. However, NLPs are usually too computationally expensive for resource-constrained users. Fortunately, cloud computing provides an alternative and economical service for resource-constrained users to outsource their computation tasks to the cloud. However, one major concern with outsourcing NLPs is the leakage of user's private information contained in NLP formulations and results. Although much work has been done on privacy-preserving outsourcing of computation tasks, little attention has been paid to NLPs. In this paper, we for the first time investigate secure outsourcing of general large-scale NLPs with nonlinear constraints. A secure and efficient transformation scheme at the user side is proposed to protect user's private information; at the cloud side, generalized reduced gradient method is applied to effectively solve the transformed large-scale NLPs. The proposed protocol is implemented on a cloud computing testbed. Experimental evaluations demonstrate that significant time can be saved for users and the proposed mechanism has the potential for practical use.Comment: Ang Li and Wei Du equally contributed to this work.

    Objectives To report the prevalence of Health Related Quality of Life (HRQOL) in foreign-born Asian Americans (AA) and to compare this with the general AA from 2010 BRFSS data. To examine the influential factors associated with HRQOL-4 including English proficiency, perceived racial discrimination, smoking, alcohol use, and sociodemographics. Background Quality of life (QOL) represents individuals’ subjective perception of multidimensional aspects of life including physical, psychological, social and spiritual aspects. HRQOL represents the physical and mental health domain of QOL. Centers for Disease Control and Prevention (CDC) has been measuring HRQOL to capture people’s overall perceptions about their health; HRQOL has become an important component of health surveillance (U.S. DHHS, 2000). While acculturation and racial discrimination have been negatively associated to the number of chronic health conditions and well-being of AA, their influence on HRQOL has not been studied. Public surveillance study has typically considered Asian Americans as a single group and little is known about how HRQOL and health-related risk factors vary among foreign-born Asian Americans including Chinese-, Korean-, and Vietnamese- Americans.

    Computational modelling of emboli travel trajectories in cerebral arteries: Influence of microembolic particle size and density

    Get PDF
    This article has been made available through the Brunel Open Access Publishing Fund.Ischaemic stroke is responsible for up to 80 % of stroke cases. Prevention of the reoccurrence of ischaemic attack or stroke for patients who survived the first symptoms is the major treatment target. Accurate diagnosis of the emboli source for a specific infarction lesion is very important for a better treatment for the patient. However, due to the complex blood flow patterns in the cerebral arterial network, little is known so far of the embolic particle flow trajectory and its behaviour in such a complex flow field. The present study aims to study the trajectories of embolic particles released from carotid arteries and basilar artery in a cerebral arterial network and the influence of particle size, mass and release location to the particle distributions, by computational modelling. The cerebral arterial network model, which includes major arteries in the circle of Willis and several generations of branches from them, was generated from MRI images. Particles with diameters of 200, 500 and 800 μ m and densities of 800, 1,030 and 1,300 kg/m 3 were released in the vessel's central and near-wall regions. A fully coupled scheme of particle and blood flow in a computational fluid dynamics software ANASYS CFX 13 was used in the simulations. The results show that heavy particles (density large than blood or a diameter larger than 500 μ m) normally have small travel speeds in arteries; larger or lighter embolic particles are more likely to travel to large branches in cerebral arteries. In certain cases, all large particles go to the middle cerebral arteries; large particles with higher travel speeds in large arteries are likely to travel at more complex and tortuous trajectories; emboli raised from the basilar artery will only exit the model from branches of basilar artery and posterior cerebral arteries. A modified Circle of Willis configuration can have significant influence on particle distributions. The local branch patterns of internal carotid artery to middle cerebral artery and anterior communicating artery can have large impact on such distributions. © 2014 The Author(s)

    CP violation Beyond the MSSM: Baryogenesis and Electric Dipole Moments

    Full text link
    We study electroweak baryogenesis and electric dipole moments in the presence of the two leading-order, non-renormalizable operators in the Higgs sector of the MSSM. Significant qualitative and quantitative differences from MSSM baryogenesis arise due to the presence of new CP-violating phases and to the relaxation of constraints on the supersymmetric spectrum (in particular, both stops can be light). We find: (1) spontaneous baryogenesis, driven by a change in the phase of the Higgs vevs across the bubble wall, becomes possible; (2) the top and stop CP-violating sources can become effective; (3) baryogenesis is viable in larger parts of parameter space, alleviating the well-known fine-tuning associated with MSSM baryogenesis. Nevertheless, electric dipole moments should be measured if experimental sensitivities are improved by about one order of magnitude.Comment: 33 pages, 6 figure

    Requirements modelling and formal analysis using graph operations

    The increasing complexity of enterprise systems requires a more advanced analysis of the representation of services expected than is currently possible. Consequently, the specification stage, which could be facilitated by formal verification, becomes very important to the system life-cycle. This paper presents a formal modelling approach, which may be used in order to better represent the reality of the system and to verify the awaited or existing system’s properties, taking into account the environmental characteristics. For that, we firstly propose a formalization process based upon properties specification, and secondly we use Conceptual Graphs operations to develop reasoning mechanisms of verifying requirements statements. The graphic visualization of these reasoning enables us to correctly capture the system specifications by making it easier to determine if desired properties hold. It is applied to the field of Enterprise modelling

    A Geometric Approach to CP Violation: Applications to the MCPMFV SUSY Model

    Get PDF
    We analyze the constraints imposed by experimental upper limits on electric dipole moments (EDMs) within the Maximally CP- and Minimally Flavour-Violating (MCPMFV) version of the MSSM. Since the MCPMFV scenario has 6 non-standard CP-violating phases, in addition to the CP-odd QCD vacuum phase \theta_QCD, cancellations may occur among the CP-violating contributions to the three measured EDMs, those of the Thallium, neutron and Mercury, leaving open the possibility of relatively large values of the other CP-violating observables. We develop a novel geometric method that uses the small-phase approximation as a starting point, takes the existing EDM constraints into account, and enables us to find maximal values of other CP-violating observables, such as the EDMs of the Deuteron and muon, the CP-violating asymmetry in b --> s \gamma decay, and the B_s mixing phase. We apply this geometric method to provide upper limits on these observables within specific benchmark supersymmetric scenarios, including extensions that allow for a non-zero \theta_QCD.Comment: 34 pages, 16 eps figures, to appear in JHE
