    Medication errors can result from administration inaccuracies at any point of care and are a major cause for concern. To develop a successful Medication Reconciliation (MR) tool, we believe it necessary to build a Work Domain Ontology (WDO) for the MR process. A WDO defines the explicit, abstract, implementation-independent description of the task by separating the task from work context, application technology, and cognitive architecture. We developed a prototype based upon the WDO and designed to adhere to standard principles of interface design. The prototype was compared to Legacy Health System's and Pre-Admission Medication List Builder MR tools via a Keystroke-Level Model analysis for three MR tasks. The analysis found the prototype requires the fewest mental operations, completes tasks in the fewest steps, and completes tasks in the least amount of time. Accordingly, we believe that developing a MR tool, based upon the WDO and user interface guidelines, improves user efficiency and reduces cognitive load.

    The LANL DC load flow model of the VEPCO transmission network shows 210 more substations than the AC load flow model produced by MZA utility Consultants. MZA was requested to determine the source of the difference. The AC load flow model used for this study utilizes 2 standard network algorithms (Decoupled or Newton). The solution time of each is affected by the number of substations. The more substations included, the longer the model will take to solve. In addition, the ability of the algorithms to converge to a solution is affected by line loadings and characteristics. Convergence is inhibited by numerous lightly loaded and electrically short lines. The MZA model reduces the total substations to 343 by creating equivalent loads and generation. Most of the omitted substations are lightly loaded and rated at 115 kV. The MZA model includes 16 substations not included in the LANL model. These represent new generation including Non-Utility Generator (NUG) sites, additional substations and an intertie (Wake, to CP and L). This report also contains data from the Italian State AC power flow model and the Duke Power Company AC flow model.

    The inflationary cosmology paradigm is very successful in explaining the CMB anisotropy to the percent level. Besides the dependence on the inflationary model, the power spectra, spectral tilt and non-Gaussianity of the CMB temperature fluctuations also depend on the initial state of inflation. Here, we examine to what extent these observables are affected by our ignorance in the initial condition for inflationary perturbations, due to unknown new physics at a high scale M. For initial states that satisfy constraints from backreaction, we find that the amplitude of the power spectra could still be significantly altered, while the modification in bispectrum remains small. For such initial states, M has an upper bound of a few tens of H, with H being the Hubble parameter during inflation. We show that for M ∼ 20H, such initial states always (substantially) suppress the tensor to scalar ratio. In particular we show that such a choice of initial conditions can satisfactorily reconcile the simple ½m 2 φ 2 chaotic model with the Planck data [1-3

    Full Text Available Traditional quantum-inspired genetic algorithm (QGA has drawbacks such as premature convergence, heavy computational cost, complicated coding and decoding process etc. In this paper, a novel real-coded quantum-inspired genetic algorithm is proposed based on interval division thinking. Detailed comparisons with some similar approaches for some standard benchmark functions test validity of the proposed algorithm. Besides, the proposed algorithm is used in two typical nonlinear data reconciliation problems (distilling process and extraction process and simulation results show its efficiency in nonlinear data reconciliation problems.

    Highlights: → We present a Model Selection, Robust Data Reconciliation and Outlier Detection method. → The novel method directly minimizes the Robust Akaike Information Criteria. → We use Hampel's redescending estimator and a slight modified objective function. → We obtain a good performance using the Particle Swarm Optimization Algorithm. → Simulations are made including a simplified Thermal Reactor Power calculation. - Abstract: Data Reconciliation (DR) and Gross Errors Detection (GED) are techniques of increasing interest in Nuclear Power Plants and used in order to keep Mass and Energy balance into account. These Techniques have been extensively studied in Chemical and Petrochemical Industry due to its benefits, which include closing the mass and energy balance and the yield of promising financial results. Many techniques were developed to solve Data Reconciliation and Outlier Detection, some of them use, for example, Quadratic Programming, Lagrange Multipliers, Mixed-Integer NonLinear Programming and others use Evolutionary Algorithms like Genetic Algorithms (GA) and Particle Swarm Optimization (PSO). Nowadays, Robust Statistics is also increasing in interest and it is being used in order to surpass some methods limitation, e.g., assuming that the errors are Normally Distributed, which does not always reflects real problems situation. In this paper we present a novel method to perform simultaneously: (a) the tuning of the Hampel's Three Part Redescending Estimator (HTPRE) constants; (b) the Robust Data Reconciliation and (c) the Gross Error Detection. The automatic tuning procedure is based on the minimization of the Robust Akaike Criteria and the Particle Swarm Algorithm is used as a global optimization method. Simulations were made considering a nonlinear process commonly used as a benchmark by several authors and also in calculating the Thermal Reactor Power based on a simplified example. The results show the potential use of the technique even in

    Preventable medication errors impact substantially on the Australian healthcare system. Where 'poor communication of medical information at transition points is responsible for as many as 50% of all medication errors', a leading contributor for this type of medication error is lack of consumer knowledge about medicines information. This study was aimed at designing and testing the effectiveness of a consumer-healthcare professional partnership model towards effective medication reconciliation. This model aims to empower consumers about their medicines information, so that they would contribute more effectively to medication reconciliation and thereby minimise medication errors occurring at transition points. Components of this model were informed by qualitative data gleaned from patient opinion surveys, focus group sessions involving nurses, doctors and pharmacists working at the hospital and results of a literature search of medication safety tools. Programme development was informed by health improvement approaches centred on a Plan-Do-Study-Act cycle. Evaluation for effectiveness was conducted within a framework of a controlled before and after study. revealed that there was a 1.4-fold increase in the reporting rate of pharmacists intervention. The study could not demonstrate that the designed intervention was effective in minimising near-misses. However, there is statistically insignificant reduction in errors for patients that were correctly exposed to the intervention. Anecdotal evidence suggests there is utility for a patient population keen to claim greater ownership of their medicines information. Further, we advocate that patient education about medicines and the establishment of a consumer-healthcare professional model occur prior to ward admission.

    Schweitzer, Eugene J

    2012-01-01

    Cloud computing refers to subscription-based, fee-for-service utilization of computer hardware and software over the Internet. The model is gaining acceptance for business information technology (IT) applications because it allows capacity and functionality to increase on the fly without major investment in infrastructure, personnel or licensing fees. Large IT investments can be converted to a series of smaller operating expenses. Cloud architectures could potentially be superior to traditional electronic health record (EHR) designs in terms of economy, efficiency and utility. A central issue for EHR developers in the US is that these systems are constrained by federal regulatory legislation and oversight. These laws focus on security and privacy, which are well-recognized challenges for cloud computing systems in general. EHRs built with the cloud computing model can achieve acceptable privacy and security through business associate contracts with cloud providers that specify compliance requirements, performance metrics and liability sharing.

    Full Text Available The paper present the results of the survey that was designed to examine attitudes towards reconciliation, traumatic experience, as well as some basic values, attitudes and stereotypes in two cities of the former Yugoslavia where the nationalities that were in conflict live together. The survey was conducted on 400 subjects in Vukovar (inhabited by Serbs and Croats and 400 subjects in Prijedor (Serbs and Bosniaks. The results show that the level of traumatic experience, as a single variable, has no correlation with the readiness for reconciliation. On the other hand, in General Linear Model, best predictors of the readiness for reconciliation were attitudes and values represented by the factors “Non-Ethnocentric” and Non-Nationalistic/ Xenophobic”. Also, having friends among the “opposing” nationality and having positive experiences with the members of opposing national groups is highly related to a readiness for reconciliation. Finally, a belief in war crime trials, combined with a readiness to admit the war crimes among its own nationality, was a significant predictor of readiness for reconciliation.

  19. Trophic modelling of the Peruvian upwelling ecosystem: Towards reconciliation of multiple datasets

    Science.gov (United States)

    Guénette, Sylvie; Christensen, Villy; Pauly, Daniel

    2008-10-01

    In the 1980s, personnel from the Instituto del Mar del Peru collaborated with foreign experts to reconstruct time series of (1) catch and biomass of the Peruvian anchovy Engraulis ringens back to 1953, along with parallel time series of (2) abundance of anchovy predators and competitors, and (3) abiotic parameters indicative of the dynamics of the Peruvian upwelling system. This contribution documents an attempt to build an ecosystem model of the Peruvian upwelling ecosystem and recreate the observed biomass trends through the period 1953-1984, using the Ecopath with Ecosim (EwE) software. The time series of biomass, particularly of Peruvian anchovy and its various predators, are not reproduced by the EwE model based solely on the original parameters. Instead, to model the anchovy abundance fluctuations caused by El Niño and other oceanographic events, it is necessary to include mechanisms that were not part of the original description of the ecosystem, which focused on mass-balance. For example, a switch between large and small phytoplankton appears to be required to induce the observed abundance shifts between sardine and anchovy. Similarly, a ‘mitigating’ relationship must be assumed between bonito ( Sarda chilensis) and seabirds for the 1965 collapse of seabirds to be reproduced by the model. Mechanisms of this sort, here proposed in a very tentative fashion, will have to be firmly established and quantified before a model can successfully explain both the older data series (1953-1984) as done here, and eventually the new series on the Peruvian upwelling system that became available only recently. With a total of now over 50 years of data, this would represent one of the best documented marine ecosystems in the world, matching its status as one of the most productive.

  20. Pore Formation During Solidification of Aluminum: Reconciliation of Experimental Observations, Modeling Assumptions, and Classical Nucleation Theory

    Yousefian, Pedram; Tiryakioğlu, Murat

    2018-02-01

    An in-depth discussion of pore formation is presented in this paper by first reinterpreting in situ observations reported in the literature as well as assumptions commonly made to model pore formation in aluminum castings. The physics of pore formation is reviewed through theoretical fracture pressure calculations based on classical nucleation theory for homogeneous and heterogeneous nucleation, with and without dissolved gas, i.e., hydrogen. Based on the fracture pressure for aluminum, critical pore size and the corresponding probability of vacancies clustering to form that size have been calculated using thermodynamic data reported in the literature. Calculations show that it is impossible for a pore to nucleate either homogeneously or heterogeneously in aluminum, even with dissolved hydrogen. The formation of pores in aluminum castings can only be explained by inflation of entrained surface oxide films (bifilms) under reduced pressure and/or with dissolved gas, which involves only growth, avoiding any nucleation problem. This mechanism is consistent with the reinterpretations of in situ observations as well as the assumptions made in the literature to model pore formation.

    Full Text Available Gaps in information about patient medication adherence may contribute to preventable adverse drug events and patient harm. Hence, health-quality advocacy groups, including the Joint Commission, have called for the implementation of standardized processes to collect and compare patient medication lists. This manuscript describes the implementation of a self-service patient kiosk intended to check in patients for a clinic appointment and collect a medication adherence history, which is then available through the electronic health record. We used business process engineering and simulation modeling to analyze existing workflow, evaluate technology impact on clinic throughput, and predict future infrastructure needs. Our empiric data indicated that a multi-function healthcare kiosk offers a feasible platform to collect medical history data. Furthermore, our simulation model showed a non-linear association between patient arrival rate, kiosk number, and estimated patient wait times. This study provides important data to help administrators and healthcare executives predict infrastructure needs when considering the use of self-service kiosks.

  2. Technology Reconciliation in the Remote Sensing ERA of United States Civilian Weather Forecasting: 1957 -1987.

    Courain, Margaret Eileen

    This dissertation seeks to advance an understanding of the management of a major technological change in meteorology. The study examines the connection between changes in production and real-time use of data products derived from remote -sensing data collection and the evolution of U.S. civilian weather forecasting 1957-1987. The role of data collection in weather forecasting throughout history is examined, giving most attention to the 1957-1987 period. Critical to the real-time use of remote-sensing data was technology reconciliation. As defined by the author, it is the function or process by which data products and information derived from a new technology are made consistent or congruent with the existing data representations of a science in order to be used effectively. No model had been developed for a technology reconciliation process, or definition of the major role technology reconciliators played in the 30-year evolution of the science of weather forecasting. In order to assess the new remote-sensing data resource and its use in U.S. civilian weather forecasting, a Data Accountability and Review Technique (DART) was developed by the author in 1989. This technique was used to identify 16 of the technology reconciliators who developed and reconciled 25 new remote-sensing data products with the weather charts, maps and computer models of the National Weather Service. In five separate program teams, they were responsible for 15 improvements in the products--forecasts--and 18 improvement in the process of weather forecasting. A model of the technology reconciliation is proposed which can be applied to understanding the contemporary history of other sciences. The model, as well as the methods developed by the author to recognize the process of technology reconciliation has a much more general applicability beyond the sciences. Any field implementing new technology that promises to improve its whole way of working will be faced with the task of technology

    The procedure known as data reconciliation is based on measurement adjustments so that the resulting values fit within the conservation laws and the restrictions imposed by the process. The classical general data reconciliation problem deals with a weighted least-squares minimization of the measurement adjustments subject to the model constraints. The reconciliation technique allows that two or more experimental redundant measurements can be reconciled to a single value, a better representation of the quantity to be analyzed, minimizing the measurement uncertainty. A critical step in this process is the acquisition and storage of long-term data. There are commercial applications available to solve this problem, although in many cases they don't apply to the plants particularities and, in cases they do, the presented solution is usually more complex and expensive. The purpose of this work was to develop a custom tool for volume data reconciliation on oil products storage and transportation plants using the process data stored on a PIMS server. The platform chosen for this development was an Excel environment. The main novelty presented in this tool is the intrinsic simplicity gained by using an Excel environment, due to its wide range usage facilitating the customization for different plants without extra costs for the company.

    Full Text Available In South Africa scholars in the broad field of practical theology are currently faced with a daunting challenge: to rethink the reconciling role of the institutional church in the light of continued challenges facing reconciliation within post-apartheid and post-Truth and Reconciliation Commission (TRC South Africa. This contribution investigates whether the transdisciplinary, region-centred scientific research approach with a focus on the Hölderlin perspective on reconciliation could assist scholars in practical theology to address reconciliation in a post-apartheid and post-TRC society. The article proposes a contextual and constructive approach to reconciliation in order to assist South African scholars in the field of practical theology and the institutional church to address the challenges of reconciliation in a post-apartheid and post-TRC society. The contribution confirms that this approach does indeed assist the field of practical theology to contribute to reconciliation without the risk of speaking a language that nobody beyond theology can understand.

Even in such a short workshop, it seemed that it was possible to share difficult areas of the past, and move on to looking at hopes for the future. The use of art materials seemed to facilitate the expression of aspects difficult to put into words. There seems to be potential for extending this method. Yet it is not without its dangers, if used with a vulnerable group of people, or in an insecure situation, or in an insensitive way. It could open doors which are difficult to shut again. The ability of art to bring up memories and emotions is both its strength and its risk.

    Using the medicines reconciliation tool which involves preparing an updated list of patient's medications at each transition of care can significantly enhance patient safety. The pharmacist has been leading this process in western healthcare systems. Little is known about pharmacists' role in medicines reconciliation in Middle Eastern Countries. To explore the implementation of medicines reconciliation in Kuwait hospitals, pharmacists' role in this process and perceptions of the challenges in implementing it in practice. This was an exploratory descriptive study of medicines reconciliation practices at eleven secondary/tertiary hospitals in Kuwait. A mixed-methods research design was used whereby 110 hospital pharmacists participated in 11 focus groups and 88 of them completed self-administered surveys. Participants reported that medicines reconciliation is poorly applied in hospitals and that they had limited role in the process. The current medicines reconciliation policy does not assign any responsibilities for pharmacists in this process. The most significant barriers to applying medicines reconciliation by pharmacists were inadequate staff numbers, lack of time, difficult access to patient information, lack of policy to support pharmacist role and patients' poor knowledge about their medications. Hospital pharmacists in Kuwait advocate implementing medicines reconciliation but report significant strategic/operational barriers to its application. Efforts are needed in policy reform and team training to enable pharmacists provide effective patient care services including medicines reconciliation. Copyright © 2018 Elsevier B.V.

    Full Text Available This article represents a trilogy of tribute to and by Jürgen Moltmann on 05 and 06 April 2017 during the centenary celebrations of the Faculty of Theology at the University of Pretoria and the conferment of an honorary doctorate to Moltmann. The first tribute to Prof. Moltmann is an address from the General Secretary, World Council of Churches, Geneva, Switzerland, Rev. Dr Olav Fykse Tveit. In this he honours Professor Moltmann’s prophetic reflection on how theology can bring the living God we all believe in to the world today, so that human beings and the entire creation can experience the fullness of life that God promised to us all. The second tribute is authored by Klaus Nürnberger, in which he reflects on Moltmann’s legacy for South Africans. The second part is Prof. Moltmann’s acceptance speech at the graduation ceremony on 06 April when he addressed the new graduandi and their families and friends at the Rembrandt Hall, University of Pretoria. He inspires the newly graduandi by saying: ‘In the end – there is a beginning. Young men and women, let your hope arise. We have so much of sick and dying hope around us. There is resignation. There is the arrogance of the powerful, and there is the apathy of powerless. Drop arrogance and learn to listen to others. Get out of apathy and lift up your head and raise your voices. Break out of indifference and get involved. Life is so beautiful’. The last section echoes Moltmann’s lifelong emphasis on the living power of hope and focuses on the power of forgiveness to mend broken relationships. This is not an easy task, and where it is up to humanity, utterly impossible to cross the divides the human condition can create. Moltmann focuses on how the reconciliation of Christ with humanity creates bridges for humanity to reconcile with one another. Reconciliation restores relationships and opens a ‘gateway’ to the future. In this way, Moltmann highlighted the theme of the centenary

    .7% were rated as potentially harmful. A multivariate logistic regression model showed that patients aged ≥65 years, polypharmacy, and prescriptions for hypoglycemic drugs and warfarin were more likely associated with reconciliation errors. Conclusion: There is a high failure rate in medication reconciliation process in patients admitted to the medical and surgical department. The reconciliation process proves to be a useful tool since nearly half of avoided reconciliation errors were unintentional and had the potential for harm. This strategy, based on our results and the difficulty of applying the process to all patients should be directed primarily to the patients at increased risk of error.

    The concept of predictive microbiology has developed rapidly through the initial phases of experimental design and model development and the subsequent phase of model validation. A fully validated model represents a general rule which may be brought to bear on particular cases. For some microorganism/food combinations, sufficient confidence now exists to indicate substantial benefits to the food industry from use of predictive models. Several types of devices are available to monitor and record environmental conditions (particularly temperature). These "environmental histories" can be interpreted, using predictive models, in terms of microbial proliferation. The current challenge is to provide systems for the collection and interpretation of environmental information which combine ease of use, reliability, and security, providing the industrial user with the ability to make informed and precise decisions regarding the quality and safety of foods. Many specific applications for predictive modeling can be developed from a basis of understanding the inherent qualities of a fully validated model. These include increased precision and confidence in predictions based on accumulation of quantitative data, objective and rapid assessment of the effect of environmental conditions on microbial proliferation, and flexibility in monitoring the relative contribution of component parts of processing, distribution, and storage systems for assurance of shelf life and safety.

  12. Report of the 2013 AMCP Partnership Forum on electronic solutions to medication reconciliation and improving transitions of care.

    Science.gov (United States)

    2014-09-01

    The Affordable Care Act (ACA) is driving the evolution of reimbursement from a fee-for-service model to an outcomes-based system. Accountable care organizations (ACOs) are 1 component of this evolution, and 1 of their charges is to reduce hospital readmission rates for key diagnoses such as congestive heart failure (CHF) and other cardiovascular comorbidities. Lack of patient follow-up and adherence are 2 major causes of readmission. Providing strong medication management is 1 of the common factors in successful readmission programs. We discuss here how electronic solutions might strengthen these medication management programs. To explore the key issues and strategies that affect the use of electronic medication reconciliation processes and to identify the role the Academy of Managed Care Pharmacy (AMCP) can play in spearheading the adoption of electronic solutions. This was a descriptive analysis of the medication reconciliation process and the factors that promote or limit the application of electronic solutions to medication reconciliation and transitions of care processes. AMCP convened a panel of managed care, hospital, community, ACO, and medication therapy management pharmacists; technology vendors; and other health care stakeholders with an expertise or interest in transitions of care. In the last few years, there has been considerable uptake of electronic solutions to the admission medication reconciliation process, largely due to increasing penetration of vendors using sophisticated medication history tools. The current electronic solutions to the admission medication reconciliation record are remarkably similar in content. Some pilots for electronic solutions to discharge medication reconciliation are emerging. The focus group recommended specific programs AMCP can pursue to increase the adoption of electronic solutions for medication reconciliation. One important aspect to address is developing a business case that documents the return on investment

    Medication reconciliation is a major component of safe patient care. One of the main problems in the implementation of a medication reconciliation process is the lack of human resources. With limited resources, it is better to target medication reconciliation resources to patients who will derive the most benefit from it. The primary objective of this study was to determine the frequency and types of medication reconciliation errors identified by pharmacists performing medication reconciliation at admission. Each medication error was rated for its potential to cause patient harm during hospitalization. A secondary objective was to determine risk factors associated with medication reconciliation errors. This was a prospective, single-center pilot study conducted in the internal medicine and surgical wards of a tertiary care teaching hospital in the Eastern province of Saudi Arabia. A clinical pharmacist took the best possible medication history of patients admitted to medical and surgical services and compared with the medication orders at hospital admission; any identified discrepancies were noted and analyzed for reconciliation errors. Multivariate logistic regression was performed to determine the risk factors related to reconciliation errors. A total of 328 patients (138 in surgical and 198 in medical) were included in the study. For the 1419 medications recorded, 1091 discrepancies were discovered out of which 491 (41.6%) were reconciliation errors. The errors affected 177 patients (54%). The incidence of reconciliation errors in the medical patient group was 25.1% and 32.0% in the surgical group (perror was the omission (43.5% and 51.2%). Lipid-lowering (12.4%) and antihypertensive agents were most commonly involved. If undetected, 43.6% of order errors were rated as potentially requiring increased monitoring or intervention to preclude harm; 17.7% were rated as potentially harmful. A multivariate logistic regression model showed that patients aged ≥65 years

  16. Schedule reconciliation tests for management prudency determination

    International Nuclear Information System (INIS)

    Howell, G.E.

    1986-01-01

    The prudency audit of a nuclear project involves engineering, construction, financial, and management dimensions. The audit must retrospectively evaluate the decisions and actions of management decision makers and then equitably allocate the cost impacts of those decisions and actions in a comprehensive and objective manner. In most situations, determination of the impact of schedule delays is a paramount issue. Manzi and Associates uses an approach to schedule reconciliation that focuses on the site-specific, as-built condition. The as-built schedule model is analyzed by a backward pass, or but-for methodology which focuses on the causes and impacts of identified delays. The objective is to demonstrate that but-for the identified delay, the project could have been built in the as-planned time frame. The but-for methodology has been used in many contract dispute cases and is currently being applied to schedule reconciliation on several nuclear plants. The potential for applying this methodology to both new construction and retrofit projects is great

    2015-11-01

    Full Text Available Armed violence and genocide are among the on-going problems that are still facing contemporary Africa and the world. In the aftermath of the outrages, devastation and appalling carnage of the Second World War, member states of the United Nations (UN undertook radical steps, inter alia, "to save succeeding generations from the scourge of war and to reaffirm faith in fundamental human rights". Subsequently, the International Bill of Human Rights was proclaimed in order to lay down international human rights norms and standards of conduct and to prevent the recurrence of mass killings. Although Burundi is a State Party to the UN and African Union and is a signatory to a number of international and regional human rights treaties, the post-colonial history of Burundi is an epic tale of indescribable human suffering and misery as a result of systematic mass killings. At least every family or household in Burundi has been negatively affected by the mass killings of the 1960s, 1972, 1988 and 1990s, which have created a significant number of refugees and internally displaced persons (IDPs.This article traces the root causes of Burundi's systemic armed violence and argues that despite several UN Security Council Resolutions and peace agreements aimed at national reconciliation and reconstruction, mass killings and other heinous crimes remain unaddressed. The article recommends that a comprehensive transitional justice model is required in post-conflict Burundi in order to bring about national reconciliation, healing and reconstruction.

  18. Exact Algorithms for Duplication-Transfer-Loss Reconciliation with Non-Binary Gene Trees.

    Science.gov (United States)

    Kordi, Misagh; Bansal, Mukul S

    2017-06-01

    Duplication-Transfer-Loss (DTL) reconciliation is a powerful method for studying gene family evolution in the presence of horizontal gene transfer. DTL reconciliation seeks to reconcile gene trees with species trees by postulating speciation, duplication, transfer, and loss events. Efficient algorithms exist for finding optimal DTL reconciliations when the gene tree is binary. In practice, however, gene trees are often non-binary due to uncertainty in the gene tree topologies, and DTL reconciliation with non-binary gene trees is known to be NP-hard. In this paper, we present the first exact algorithms for DTL reconciliation with non-binary gene trees. Specifically, we (i) show that the DTL reconciliation problem for non-binary gene trees is fixed-parameter tractable in the maximum degree of the gene tree, (ii) present an exponential-time, but in-practice efficient, algorithm to track and enumerate all optimal binary resolutions of a non-binary input gene tree, and (iii) apply our algorithms to a large empirical data set of over 4700 gene trees from 100 species to study the impact of gene tree uncertainty on DTL-reconciliation and to demonstrate the applicability and utility of our algorithms. The new techniques and algorithms introduced in this paper will help biologists avoid incorrect evolutionary inferences caused by gene tree uncertainty.

  19. Macro-Integration for Solving Large Data Reconciliation Problems

    2014-04-01

    Full Text Available Macro-integration technique is a well established method forreconciliation of large, high-dimensional tables, especially applied to macroeconomic data at national statistical oces (NSO. This technique is mainly used when data obtained from dierent sources should be reconciled on a macro level. New areas of applications for this technique arise as new data sources become available to NSO's. Often these new data sources cannot be combined on a micro level, while macro integration could provide a solution for such problems. Yet, more research should be carried out to investigate if in such situations macro integration could indeed be applied. In this paper we propose two applications of macro-integration techniques in other domains than the traditional macro-economic applications. In particular: reconciliation of tables of a virtual census and reconciliation of monthly series of short term statistics gures with the quarterly gures of structural business statistics.

  2. Multi-Purpose Optimization for Reconciliation Ecology on an Engineered Floodplain: Yolo Bypass, California

    2016-03-01

    Full Text Available doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art5Floodplains in California and elsewhere are productive natural habitats with high levels of biodiversity, yet today they are often permanently disconnected from rivers by urban or agricultural development and flood management structures. This disconnection poses a threat to many native fish, bird and other species that evolved to take advantage of seasonal floodplain inundation. The traditional restoration approach to this problem is to recreate historical floodplain by restoring natural hydrologic and successional processes. However levees, dams, and development have made this largely impossible in much of the developed world. Reconciliation ecology recognizes this limitation, and encourages instead the re-engineering of human dominated landscapes to allow for coexistence of native species and human uses. Flood control bypasses are particularly promising places to reconcile historical fish and bird uses of floodplain habitats with human uses. However, the reconciliation approach requires nuanced management of a complex system. Using the Yolo Basin flood bypass in California’s Central Valley as an example, this study develops formal multi-objective optimization to help planners identify management options that best improve habitat quality for fish and birds with minimal costs to farmers or wetland managers. Models like the one developed here can integrate large amounts of data and knowledge, and offer an explicit accounting of relationships and trade-offs between different objectives. This is especially useful in reconciliation planning, where many uses and variables interact on a landscape, and deliberate re-engineering requires consideration of many decisions simultaneously. Initial results suggest that modest land-use changes and inundation management strategies can significantly improve seasonal bird and fish habitat quality at little cost to farmers or other human land uses. The model

  3. Reconciliation of global temperatures

    Science.gov (United States)

    Benestad, R. E.

    2012-03-01

    In recent years there has been a public debate about whether the rate of global warming has waned, prompting the paper 'Is the climate warming or cooling?' in Geophysical Research Letters by Easterling and Wehner (2009). This question has also attracted attention in wider scientific circles, and in a recent paper in Science, Solomon et al (2010) suggested that a decrease in stratospheric water vapour concentrations has slowed the global surface temperature rate between 2000 and 2009. Yet another study by Kaufmann et al (2011) argued that the 'hiatus' in the global warming coincided with near constant combined anthropogenic and natural forcings. The reason: a declining solar insolation, a shift to La Niña conditions and a rapid growth in short-lived sulfur emissions have masked the effect from rising greenhouse gas concentrations (GHGs). So, what is new? In the paper 'Global temperature evolution 1979-2010', Foster and Rahmstorf (2011) re-examine the situation. Whereas Kaufmann's group only examined the global temperature record from the Hadley Centre and Climate Research Unit (HadCRUT3; Brohan et al 2006) in the United Kingdom, Foster and Rahmstorf present an analysis of the range of available historical temperature records, both from surface thermometers and satellite-based remote sensing. There is one caveat associated with the analysis that Kaufmann's group carried out, which is that the HadCRUT3 record does not fully capture recent enhanced warming over the Arctic, thereby underestimating the evolution of the true global mean compared with other sources. Other analyses, such as the one from NASA/GISS (GISSTEMP; Hansen et al 2010) and those based on atmospheric models (e.g. Kalnay et al 1996), cover the Arctic region better by interpolating the values surrounding the data void or taking physics into account. These, and independent indices such as sea-ice extent (Kinnard et al 2011), ice melting over Greenland (Mernild et al 2009) and permafrost thawing

  4. Data Reconciliation and Gross Error Detection: A Filtered Measurement Test

    International Nuclear Information System (INIS)

    Himour, Y.

    2008-01-01

    Measured process data commonly contain inaccuracies because the measurements are obtained using imperfect instruments. As well as random errors one can expect systematic bias caused by miscalibrated instruments or outliers caused by process peaks such as sudden power fluctuations. Data reconciliation is the adjustment of a set of process data based on a model of the process so that the derived estimates conform to natural laws. In this paper, we will explore a predictor-corrector filter based on data reconciliation, and then a modified version of the measurement test is combined with the studied filter to detect probable outliers that can affect process measurements. The strategy presented is tested using dynamic simulation of an inverted pendulum

    2014-06-15

    Phylogenetic tree reconciliation is a widely used method for reconstructing the evolutionary histories of gene families and species, hosts and parasites and other dependent pairs of entities. Reconciliation is typically performed using maximum parsimony, in which each evolutionary event type is assigned a cost and the objective is to find a reconciliation of minimum total cost. It is generally understood that reconciliations are sensitive to event costs, but little is understood about the relationship between event costs and solutions. Moreover, choosing appropriate event costs is a notoriously difficult problem. We address this problem by giving an efficient algorithm for computing Pareto-optimal sets of reconciliations, thus providing the first systematic method for understanding the relationship between event costs and reconciliations. This, in turn, results in new techniques for computing event support values and, for cophylogenetic analyses, performing robust statistical tests. We provide new software tools and demonstrate their use on a number of datasets from evolutionary genomic and cophylogenetic studies.

    In Nuclear power plants, Data Reconciliation (DR) and Gross Errors Detection (GED) are techniques of increasing interest and are primarily used to keep mass and energy balance into account, which brings outcomes as a direct and indirect financial benefits. Data reconciliation is formulated by a constrained minimization problem, where the constraints correspond to energy and mass balance model. Statistical methods are used combined with the minimization of quadratic error form. Solving nonlinear optimization problem using conventional methods can be troublesome, because a multimodal function with differentiated solutions introduces some difficulties to search an optimal solution. Many techniques were developed to solve Data Reconciliation and Outlier Detection, some of them use, for example, Quadratic Programming, Lagrange Multipliers, Mixed-Integer Non Linear Programming and others use evolutionary algorithms like Genetic Algorithms (GA) and recently the use of the Particle Swarm Optimization (PSO) showed to be a potential tool as a global optimization algorithm when applied to data reconciliation. Robust Statistics is also increasing in interest and it is being used when measured data are contaminated by random errors and one can not assume the error is normally distributed, situation which reflects real problems situation. The aim of this work is to present a brief comparison between the classical data reconciliation technique and the robust data reconciliation and gross error detection with swarm intelligence procedure in calculating the thermal reactor power for a simplified heat circuit diagram of a steam turbine plant using real data obtained from Angra 2 Nuclear power plant. The main objective is to test the potential of the robust DR and GED method in a integrated framework using swarm intelligence and the three part redescending estimator of Hampel when applied to a real process condition. The results evaluate the potential use of the robust technique in

    Full Text Available Preventable adverse drug events occur frequently at transitions in care and are a problem for many patients following hospital discharge. Many of these problems can be attributed to poor medication reconciliation. The purpose of this study was to assess the impact that direct pharmacist involvement in the discharge medication reconciliation process had on medication discrepancies, patient outcomes, and satisfaction. A cohort study of 70 patients was designed to assess the impact of pharmacist facilitated discharge medication reconciliation at a 204-bed community hospital in Battle Creek, Michigan, USA. Discharge summaries were analyzed to compare patients who received standard discharge without pharmacist involvement to those having pharmacist involvement. The total number of discrepancies in the group without pharmacist involvement was significantly higher than that of the pharmacist facilitated group.

    Full Text Available Work-family reconciliation plays a crucial role in the well-being of employees, having impacts at the individual, social and organizational level. Studies concluded that poor work-life balance as one of the ten predictors of psychosocial risks at work. A family-friendly culture relates to how an organization values and allows the articulation of the various spheres of its workers’ life. We intended to determine the effect of different variables like the existence of services, the organizational culture and the managers and colleagues support, on the stress experienced. A sample of 156 employees, from five organizations in the same region of Portugal, responded to a survey contributing to the empirical results of the study. We have conducted a structural equation model to test whether the factor solution of the perception of the reconciliation capability - STRESS model demonstrated a goodness of fit to the population studied. We’ve concluded that more important than the existence of reconciliation services, the perception of a supportive organizational culture, namely by colleagues and supervisors has great influence in reconciliation capability and by that way on work stress feelings. This might explain why workers do not use all the spectrum of resources provided by organizations and states to work-life reconciliation.

  13. Genome-scale metabolic model of the fission yeast Schizosaccharomyces pombe and the reconciliation of in silico/in vivo mutant growth

    Science.gov (United States)

    2012-01-01

    Background Over the last decade, the genome-scale metabolic models have been playing increasingly important roles in elucidating metabolic characteristics of biological systems for a wide range of applications including, but not limited to, system-wide identification of drug targets and production of high value biochemical compounds. However, these genome-scale metabolic models must be able to first predict known in vivo phenotypes before it is applied towards these applications with high confidence. One benchmark for measuring the in silico capability in predicting in vivo phenotypes is the use of single-gene mutant libraries to measure the accuracy of knockout simulations in predicting mutant growth phenotypes. Results Here we employed a systematic and iterative process, designated as Reconciling In silico/in vivo mutaNt Growth (RING), to settle discrepancies between in silico prediction and in vivo observations to a newly reconstructed genome-scale metabolic model of the fission yeast, Schizosaccharomyces pombe, SpoMBEL1693. The predictive capabilities of the genome-scale metabolic model in predicting single-gene mutant growth phenotypes were measured against the single-gene mutant library of S. pombe. The use of RING resulted in improving the overall predictive capability of SpoMBEL1693 by 21.5%, from 61.2% to 82.7% (92.5% of the negative predictions matched the observed growth phenotype and 79.7% the positive predictions matched the observed growth phenotype). Conclusion This study presents validation and refinement of a newly reconstructed metabolic model of the yeast S. pombe, through improving the metabolic model’s predictive capabilities by reconciling the in silico predicted growth phenotypes of single-gene knockout mutants, with experimental in vivo growth data.

  17. Reconciliation of genome-scale metabolic reconstructions for comparative systems analysis.

    2011-03-01

    Full Text Available In the past decade, over 50 genome-scale metabolic reconstructions have been built for a variety of single- and multi- cellular organisms. These reconstructions have enabled a host of computational methods to be leveraged for systems-analysis of metabolism, leading to greater understanding of observed phenotypes. These methods have been sparsely applied to comparisons between multiple organisms, however, due mainly to the existence of differences between reconstructions that are inherited from the respective reconstruction processes of the organisms to be compared. To circumvent this obstacle, we developed a novel process, termed metabolic network reconciliation, whereby non-biological differences are removed from genome-scale reconstructions while keeping the reconstructions as true as possible to the underlying biological data on which they are based. This process was applied to two organisms of great importance to disease and biotechnological applications, Pseudomonas aeruginosa and Pseudomonas putida, respectively. The result is a pair of revised genome-scale reconstructions for these organisms that can be analyzed at a systems level with confidence that differences are indicative of true biological differences (to the degree that is currently known, rather than artifacts of the reconstruction process. The reconstructions were re-validated with various experimental data after reconciliation. With the reconciled and validated reconstructions, we performed a genome-wide comparison of metabolic flexibility between P. aeruginosa and P. putida that generated significant new insight into the underlying biology of these important organisms.

  1. Reconciliation of Gene and Species Trees

    Directory of Open Access Journals (Sweden)

    L. Y. Rusin

    2014-01-01

    Full Text Available The first part of the paper briefly overviews the problem of gene and species trees reconciliation with the focus on defining and algorithmic construction of the evolutionary scenario. Basic ideas are discussed for the aspects of mapping definitions, costs of the mapping and evolutionary scenario, imposing time scales on a scenario, incorporating horizontal gene transfers, binarization and reconciliation of polytomous trees, and construction of species trees and scenarios. The review does not intend to cover the vast diversity of literature published on these subjects. Instead, the authors strived to overview the problem of the evolutionary scenario as a central concept in many areas of evolutionary research. The second part provides detailed mathematical proofs for the solutions of two problems: (i inferring a gene evolution along a species tree accounting for various types of evolutionary events and (ii trees reconciliation into a single species tree when only gene duplications and losses are allowed. All proposed algorithms have a cubic time complexity and are mathematically proved to find exact solutions. Solving algorithms for problem (ii can be naturally extended to incorporate horizontal transfers, other evolutionary events, and time scales on the species tree.

  2. Toward a Sociology of the Reconciliation of Conflicting Desires.

    Science.gov (United States)

    O'Donnell, Susan; Perley, David

    2016-11-01

    Desire-based research provides people and communities the opportunity to share their dreams and hopes for a better future. However, conflicting desires are difficult to reconcile. We suggest that sociological research to understand conflicting desires is required to support reconciliation work by Indigenous and non-Indigenous people in Canada. Our contribution begins by identifying much of current and past sociological research about Indigenous people and communities as damaged-centered, that is, identifying problems and obstacles in the hope that the knowledge will lead to change. This model of social change is flawed. We believe that most Canadians desire justice for Indigenous peoples while at the same time desiring land and access to resources, desires that deny that justice. How we as a society reconcile these desires will determine the extent to which true justice for Indigenous peoples will be achieved. We propose a sociology of the reconciliation of conflicting desires and suggest some practical ways that this type of research could move forward. © 2016 Canadian Sociological Association/La Société canadienne de sociologie.

    To discuss the relationships between ontologies, terminologies and language in the context of Natural Language Processing (NLP) applications in order to show the negative consequences of confusing them. The viewpoints of the terminologist and (computational) linguist are developed separately, and then compared, leading to the presentation of reconciliation among these points of view, with consideration of the role of the ontologist. In order to encourage appropriate usage of terminologies, guidelines are presented advocating the simultaneous publication of pragmatic vocabularies supported by terminological material based on adequate ontological analysis. Ontologies, terminologies and natural languages each have their own purpose. Ontologies support machine understanding, natural languages support human communication, and terminologies should form the bridge between them. Therefore, future terminology standards should be based on sound ontology and do justice to the diversities in natural languages. Moreover, they should support local vocabularies, in order to be easily adaptable to local needs and practices.

    2004-01-01

    Although reconciliation in bonobos (Pan paniscus) has previously been described, it has not been analyzed heretofore by the postconflict (PC) match-control (MC) method. Furthermore, although reconciliation has been investigated before in this species, consolation has not. In this study we analyzed agonistic and affiliative contacts in all sex-class combinations to clarify and reevaluate the occurrence of reconciliation in bonobos via the PC-MC method. We also investigated the occurrence of consolation by analyzing the victims' triadic contact tendency (TCT), the influence of the sex of victims, and the relative occurrence of consolation and reconciliation. We collected 167 pairs of PC-MC observations in a captive group of bonobos (in Apeldoorn, The Netherlands). The conciliatory tendency (CCT) we obtained was tendentially lower than the mean value previously found for Yerkes captive chimpanzees. Close relationships, which were present in all female-female (FF) and some male-female (MF) dyads, positively affected reconciliation rates. When only adult PC-MC pairs (157) were considered, the mean TCTs and CCTs did not differ significantly. When we focused on types of PC affiliative contact, in the case of consolation we found a striking preference for sociosexual patterns. As to the relative occurrence of consolation and reconciliation, the highest level of the former was found in the absence of the latter. When reconciliation took place, consolation generally preceded it, suggesting that consolation may be a substitutive behavior. Our findings suggest that even if reconciliation remains the best option, consolation may be an alternative substitute for reconciliation that is used to buffer the tension originating from an unresolved conflict. Reconciliation and consolation are complex phenomena that are probably related to the life history of a group. Given that few studies have been conducted on this subject, we can not at this time make any generalizations regarding

  12. Reconciliation of equipment flexibility effects on piping system dynamic response

    Geraets, L.H.

    1987-01-01

    Piping systems are connected to equipment; if the equipment cannot be considered as ''rigid'' relative to excitation frequencies, nozzle response spectra techniques, or equipment modeling techniques are used. If the equipment is considered rigid, a fixed anchor is assumed. However, occasionally after (seismic) dynamic analysis has been completed, tests or detailed equipment dynamic analyses demonstrate that the assumption of ''infinite stiff'' is questionable. This paper reviews several classes of equipment (pumps, vessels, reservoirs, heat exchangers), and the associated (piping stresses, support loads, equipment nozzle allowables). Significant divergences between design and ''as built'' results are shown (for heat exchangers in particular). The paper discusses the reconciliation process performed for a belgian PWR plant through the use of less conservative seismic damping data (Code Case N-411)

    2003-04-01

    The management of complex waste flow systems requires a systematic approach for the handling of data, for obtaining a consistent picture of the system under consideration, and for simulating various policy scenarios and evaluating material control strategies. In this paper the implementation of a useful methodology is presented, which has been developed in previous works and is further enhanced for modelling, identifying, analysing and simulating material flow systems for which at most one measurement per flow is available for a single balancing period. The methodology enables the analyst to cope with missing data and uncertainty in the measurements. A data reconciliation procedure is used to minimise the uncertainty concerning flows by exploiting the redundancies created by restricting the available data to fulfil the available structural information. Statistical tests are introduced to enable the user to check the compatibility of the data with the a priori information. The origins analysis and destination analysis tools allow for a deeper insight into the system structure. Policy scenarios can be treated using the simulation tools. The waste flow system of the city of Vienna has been chosen to demonstrate step-by-step the procedure for building a reliable model and the effective application of the above mentioned methods and tools. Current and future research focuses on models balancing different interrelated quantities simultaneously and on incorporating stock accumulation and depletion behaviour.

    Accurate medication reconciliation at the time of hospital admission is vital to preventing adverse drug events. Compliance with medication reconciliation in our pediatric intensive care unit was low initially with overall medication reconciliation at 70%. Due to the high front line provider turnover in our unit, we focused on technological reminders for completion and used unique and innovative ways to motivate our supervising staff. Our goal was to reach >95% completion within 24 hours for medication reconciliation for all patients admitted to the pediatric intensive care unit. Pre-pilot discussions focused on examples of errors of medication reconciliation within our own institution resulting in patient harm via traditional power point presentation. The initial pilot phase instituted a job aid on how to add the medication reconciliation completion reminder column. Email updates on completion status began one week after initiation. During the implementation and spread phase, fun interactive videos were used to acknowledge roll out to the full unit. Compliance was monitored and humorous biweekly video updates emphasizing accountability were introduced. In the sustain phase, monthly video updates served as education and a reminder for provider staff. The use of a medication reconciliation completion column and reminder emails resulted in goal completion (>95%) by three weeks post intervention for the pilot unit. Overall medication reconciliation completion also reached goal of >95% completion within the entire unit after three weeks of implementation and spread. Compliance fell below goal so video updates were modified utilizing humor and emphasizing accountability. This resulted in sustained compliance now more than forty weeks post implementation. Unit compliance currently remains >95% completion within 24 hours now more than forty weeks post intervention. The use of the medication reconciliation reminder column resulted in improvement in compliance; however

We collected the results of the implementation of a TRP from September to December 2012. A pharmacist attended daily to emergency department meeting and reviewed medical history to select those patients with high risk of reconciliation error (RE according TRP. Afterwards, home medication history was elaborated with emergency department and primary care records and interview with the patient or caregiver. Therapeutic reconciliation took place with the emergency physician, considering RE any discrepancies not justified by the doctor. The potential severity of RE was assessed by emergency physicians outside the study using NCCMERP’S categorization Results: The pharmacist collected an avarage of 1,3±2,2 home medication more than the emergency physician finding 564 discrepancies with the emergency record in 95,8% of the patients. 167 were RE affecting 69 patients (71,9%. Most of the errors were due to omissions of the drugs. Acceptance by emergency physicians of the reconciliation interventions was 73,9%. 58% of the RE were considered clinically relevants. Other interventions were also performed with an acceptance of 97%. Greater compliance with risk criteria, polypharmacy and pluripathology were associated with present RE and prescription of high-risk medications with the need for intervention Conclusions: The application of TRP avoided any error in most of the patients. TRP should extend to all patients at risk who admitted by the ED.

  17. Data reconciliation and optimal operation of a Catalytic naphtha reformer

    2008-10-01

    Full Text Available The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are classified as redundant or non redundant and the model variables are classified as observable, barely observable or unobservable. The computed uncertainty of the measured and unmeasured variables shows that even if a variable is observable it may have a very large uncertainty and may thereby be practically unobservable. The process condition at 21 data points, sampled from two years of operation, was reconciled and used to optimize the process operation. There are large seasonal variations in the reformer product price and two operational cases are studied. In case 1, the product price is high and throughput is maximized with respect to process and product quality constraints. In case 2, the product price is low and the throughput is minimized with respect to a low constraint on the hydrogen production. Based on the characteristics of the optimal operation, a "self optimizing" control structure is suggested for each of the two operational cases.

    2010-01-01

    Full Text Available This paper explores transitional justice as a way to bring an end to violence and consolidate peace. It approaches transitional justice as an expression of the 'never again' consensus to prevent or prosecute crimes against humanity. It explores transitional justice as an expression of globalizing law and the implications this has for the recovery of the 'rule of law' and 'political legitimacy' in the post conflict State. It takes Robert Meister (2002's formulation of the politics of victimhood, revenge and resentment in the relationship between the beneficiaries and the victims of injustice, as remaining at the centre of transitional justice politics in trying to decide on the balance between reconciliation and justice projects. It explores how human rights discourse has been used to de-politicise the 'victim' by adopting an individually embodied concept of violence as opposed to a structural one. It argues that transitional justice as an expression of globalizing law has been primarily directed at maintaining peace to achieve closure on past 'evil' but that the beneficiary-victim issue has re-emerged in the social justice movements and renewed desire for prosecutions.

  20. Developments in Australia : native title and reconciliation

    Energy Technology Data Exchange (ETDEWEB)

    Chaney, F. [National Native Title Tribunal, Perth, WA (Australia)

    2004-07-01

    Until 1992, there was no recognition in the Australian legal system of property or other laws recognizing Indigenous rights concerning European colonial settlement and beyond. Native title was first recognized in 1992. This paper presented an outline of the history leading up to the creation of the National Native Title Tribunal in Perth, Australia, an organization whose aims are to create recognition of native title in Australia. The objects of the Native Title Act of 1993 were discussed, as well as attempts to reconcile indigenous and non-indigenous interests. Particular attention was drawn to the mining industry, as a practical example of the paradigm change in relation to indigenous rights, with an outline of the mining industry's values underlying principles concerning indigenous relations. It was concluded that while there are stringent limits on what is available through the native title process, mediation procedures mean that opportunities for agreement exist. Although reconciliation is in its infancy in Australia, there is a growing acceptance that Aboriginal rights must be considered. The agreement making which is encouraged by the native title process is an acknowledgment of a new relationship in which indigenous people are stakeholders. 72 refs., 5 figs.

  1. Accepting the truth: A step toward reconciliation

    Ilić Zoran

    2002-01-01

    Full Text Available The truth is not only about accepting the facts. The truth includes emotional components - longing for acknowledgment of mistakes and validation of painful losses and experiences. While one side in the conflict considers itself as the only victim and experiences determination and acknowledgment of the truth as a possibility for healing its own trauma through satisfaction of justice and compensation, the other side is not accepting the truth. For this other side, confrontation with the facts is a painful trauma, which endangers individual moral norms, threatens the national identity and requires, on individual level, plugging in the defense mechanism, in order to prevent penetration of painful emotions into the consciousness. Primitive psychological mechanisms of defense, focused around splitting (projection, denial, are the main obstacles in accepting the truth both on individual and group level. There is also another extreme form of reaction manifested through "hypertrophy" of the truth and one-sided self-accusation. In this paper the author presents psychological explanation of the process of accepting the truth as the prerequisite for reconciliation and transformation of the conflict.

    Medication history errors are common at admission, but can be mitigated through the implementation of medication reconciliation (MR). We designed multi-media software to assist clinicians with collection of an admission history. This manuscript describes a naturalistic usability study conducted on the hospital wards. Our goals were to 1) estimate the impact of our workflow upon departmental productivity and 2) determine the ability of our software to detect discrepancies. We furnished clinical pharmacists with our application on a tablet PC and asked them to collect a bedside history. We used 1) time-motion analysis to estimate cycle-time and 2) chart reviews to estimate error detection rates. Our intervention detected an average of 7.7 discrepancies per admission (11.7 per pharmacy-shift). A panel rated 67% of these discrepancies as 'high' or 'very high' risk. The cycle-time per admission was slightly longer than usual care processes (20.5 min vs. 17.9 min), but included a bedside interview. In general, pharmacists agreed that the technology improved the completeness and accuracy of a medication history. However, workflow leveling strategies are important to implementing a durable process. In conclusion, a pharmacist-mediated, patient-centered technology holds promise for improving the quality of MR and overall clinical performance.

    Full Text Available Objective: To analyze the outcomes of a medication reconciliation process at admission in the hospital setting. To assess the role of the Pharmacist in detecting reconciliation errors and preventing any adverse events entailed. Method: A retrospective study was conducted to analyze the medication reconciliation activity during the previous six months. The study included those patients for whom an apparently not justified discrepancy was detected at admission, after comparing the hospital medication prescribed with the home treatment stated in their clinical hospital records. Those patients for whom the physician ordered the introduction of home medication without any specification were also considered. In order to conduct the reconciliation process, the Pharmacist prepared the best pharmacotherapeutical history possible, reviewing all available information about the medication the patient could be taking before admission, and completing the process with a clinical interview. The discrepancies requiring clarification were reported to the physician. It was considered that the reconciliation proposal had been accepted if the relevant modification was made in the next visit of the physician, or within 24-48 hours maximum; this case was then labeled as a reconciliation error. For the descriptive analysis, the Statistics® SPSS program, version 17.0, was used. Outcomes: 494 medications were reconciled in 220 patients, with a mean of 2.25 medications per patient. More than half of patients (59.5% had some discrepancy that required clarification; the most frequent was the omission of a medication that the patient was taking before admission (86.2%, followed by an unjustified modification in dosing or way of administration (5.9%. In total, 312 discrepancies required clarification; out of these, 93 (29.8% were accepted and considered as reconciliation errors, 126 (40% were not accepted, and in 93 cases (29,8% acceptance was not relevant due to a change in

    South Sudan is embroiled in a conflict that erupted in December 2013. This study examines what people in South Sudan think is necessary to achieve reconciliation and how trauma exposure and PTSD are associated with those beliefs. 1525 participants (51.0% female) were selected using random and purposive sampling in six states and Abyei. Participants reported on traumatic events, PTSD symptoms, and attitudes towards reconciliation mechanisms. Results indicated that 40.7% met symptom criteria for probable PTSD. Most participants thought reconciliation was not possible without prosecuting perpetrators or compensating victims and did not support amnesty. Participants with probable PTSD were more likely to endorse confessions (OR 2.42 [1.75, 3.35]), apologies (OR 2.04 [1.46, 2.83]), and amnesty (OR 1.58 [1.21, 2.08]), and to report that compensation (OR 2.32 [1.80, 3.00]) and prosecution (OR 1.47 [1.15, 1.89]) were not necessary for reconciliation. The more traumatic events people experienced, the more they endorsed criminal punishment for perpetrators (OR 1.07 [1.04, 1.10]) and the less they endorsed confessions (OR 0.97 [0.95, 0.99]). People with PTSD may prioritize ending violence via opportunities for reconciliation, while those with more trauma exposure may support more punitive mechanisms. Policy makers should take mental health treatment and trauma into account when designing conflict mitigation, peace building, and justice mechanisms.

  7. Medication reconciliation as a strategy for preventing medication errors

    Directory of Open Access Journals (Sweden)

    Luana de Rezende Spalla

    Full Text Available ABSTRACT One of the current barriers proposed to avoid possible medication errors, and consequently harm to patients, is the medication reconciliation, a process in which drugs used by patients prior to hospitalization can be compared with those prescribed in the hospital. This study describes the results of a pharmacist based reconciliation conducted during six months in clinical units of a university hospital. Fourteen patients (23.33% had some kind of problem related to medicine. The majority (80% of medication errors were due to medication omission. Pharmaceutical interventions acceptance level was 90%. The results suggest that pharmacists based reconciliation can have a relevant role in preventing medication errors and adverse events. Moreover, the detailed interview, conducted by the pharmacist, is able to rescue important information regarding the use of drugs, allowing to avoid medications errors and patient injury.

    2014-12-01

    Full Text Available A questionnaire survey (N = 247 investigated the influence of identification with the Rwandan nation on reconciliation sentiments between members of the survivor and of the non-victim groups of the 1994 genocide in Rwanda. Results showed that, whereas the two groups did not differ in their level of identification with the nation, members of the non-victim group were more willing to reconcile than members of the survivor group. Perceived intergroup similarity mediated the effect of national identification on reconciliation sentiment for both groups, but this effect was stronger among non-victims. Finally, self-esteem during commemorations also mediated this effect, but only among non-victims. We discuss the importance of people’s motivation to reconcile with out-group members in post-genocidal contexts in light of the common in-group identity model (Gaertner & Dovidio, 2000 as well as the needs-based model of intergroup reconciliation (Nadler & Schnabel, 2008.

    Many countries require hospitals to implement medication reconciliation for accreditation, but the process is resource-intensive, thus adherence is poor. We report on the impact of prepopulating and aligning community and hospital drug lists with data from population-based and hospital-based drug information systems to reduce workload and enhance adoption and use of an e-medication reconciliation application, RightRx. The prototype e-medical reconciliation web-based software was developed for a cluster-randomized trial at the McGill University Health Centre. User-centered design and agile development processes were used to develop features intended to enhance adoption, safety, and efficiency. RightRx was implemented in medical and surgical wards, with support and training provided by unit champions and field staff. The time spent per professional using RightRx was measured, as well as the medication reconciliation completion rates in the intervention and control units during the first 20 months of the trial. Users identified required modifications to the application, including the need for dose-based prescribing, the role of the discharge physician in prescribing community-based medication, and access to the rationale for medication decisions made during hospitalization. In the intervention units, both physicians and pharmacists were involved in discharge reconciliation, for 96.1% and 71.9% of patients, respectively. Medication reconciliation was completed for 80.7% (surgery) to 96.0% (medicine) of patients in the intervention units, and 0.7% (surgery) to 82.7% of patients in the control units. The odds of completing medication reconciliation were 9 times greater in the intervention compared to control units (odds ratio: 9.0, 95% confidence interval, 7.4-10.9, P < .0001) after adjusting for differences in patient characteristics. High rates of medication reconciliation completion were achieved with automated prepopulation and alignment of community and hospital

When Ohrid Framework Agreement (OFA was signed, the international community greeted the achievements of the international community as it was signed under specific circumstances. Since it stopped the conflict, it had achieved its goal. Legally, the country became a multiethnic one with a power-sharing government. Yet, the political and intellectual elite, which slightly differ from each other, did not invest intellectual and political capital when searching for a specific Macedonian (inter national identity, which goes beyond the limitations of the ethnic definitions and mythology around them. Instead, the national discourse is emphasized. Using the terms such as multiculturalism, multhiethnicity and polylingualisam creates additional confusion. When media and politicians use these phrases and incorporate their own political discourses, the damage is done. Critical thinking is not on the agenda in the educational process and the young people are expected to listen rather than think. There is a need for a structural communication among the citizens, a social link but also a philosophical and maybe an ideological communication, so as to fill in the gaps and avoid further divisions. The only way to accomplish that is to have an open and inclusive society. In order to achieve this, the culture of dialog should be nurtured. It is not enough for Macedonians and Albanians to know each other’s folklore and cultural history. Coexistence requires knowing the modern reality. Structured communication is a key. Absence of public discourse has a positive effect on the society’s wellbeing. A debate is not a threat to the process of creating politics. Instead, it legalizes the decision-making process. The intellectual elite should take the lead, show its grandiosity, and view Macedonia as a whole in a joint narrative, which considers all the specifics of the different cultures

Gaining a better understanding of the process of reconciling medicines. Mapping the driving and restraining forces of introducing medication reconciliation. A search of the literature was conducted. 19 databases were searched using 7 different search engines. The relevance of the papers was rated by two independent experts. Data were extracted based on a previously compiled extraction tool. 230 articles were evaluated. Limits and driving forces of implementing medication reconciliation were set out. Often mentioned implementation obstacles were: communication issues, disengagement of the leaders, unpredictable resources and competence problems. Recommendations mainly consisted of process redesign techniques, presentation of cost-effectiveness data and arranging special training for staff. For improvement of medication safety in Hungarian hospitals implementing medication reconciliation should be considered. The conclusion of ongoing on-site trials as well as limits and success factors identified in this paper should taken into account.

  14. Medication Reconciliation Limitations: Observation of the Medication Reconciliation Process in the Emergency Department by Two Immersion Pharmacy Students

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Multiple medical records may exist for a particular individual based on the various health services he or she receives. Maintaining updated, accurate records remains the responsibility of both practitioners and patients. Medication reconciliation, defined as the process to accurately depict the patient’s current orders and medications, 2 seeks to avoid errors in duplicity, interactions and dosing errors. Medication histories at Moses Cone Hospital are currently recorded by pharmacy technicians who follow specific standards, for instance they cannot remove “house meds”, which are prescribed medications with an active prescription attached. Technicians instead mark these medications for removal, leaving reconciliation to the physician. The physicians in the emergency department are not required to complete a full reconciliation for patient's profiles as this is a task left for the admitting physician. This leads to the question whether the reconciliation process in the emergency department (ED needs to be re-evaluated. Patients’ “After Visit Summary” reports were used to analyze patient profiles in determining medication reconciliation statuses (whether fully reconciled, partially reconciled, or unreconciled. 280 patients’ profiles were used. 243 records (86.79% were found unreconciled, 18 (6.43% were partially reconciled, and 19 (6.79% were fully reconciled.

  15. Does electronic medication reconciliation at hospital discharge decrease prescription medication errors?

    Science.gov (United States)

    Allison, Geneve M; Weigel, Bernard; Holcroft, Christina

    2015-01-01

    Medication errors are an important patient safety issue. Electronic medication reconciliation is a system designed to correct medication discrepancies at transitions in healthcare. The purpose of this paper is to measure types and prevalence of intravenous antibiotic errors at hospital discharge before and after the addition of an electronic discharge medication reconciliation tool (EDMRT). A retrospective study was conducted at a tertiary hospital where house officers order discharge medications. In total, 100 pre-EDMRT and 100 post-EDMRT subjects were randomly recruited from the study center's clinical Outpatient Parenteral Antimicrobial Therapy (OPAT) program. Using infectious disease consultant recommendations as gold standard, each antibiotic listed in these consultant notes was compared to the hospital discharge orders to ascertain the primary outcome: presence of an intravenous antibiotic error in the discharge orders. The primary covariate of interest was pre- vs post-EDMRT group. After generating the crude prevalence of antibiotic errors, logistic regression accounted for potential confounding: discharge day (weekend vs weekday), average years of practice by prescribing physician, inpatient service (medicine vs surgery) and number of discharge mediations per patient. Prevalence of medication errors decreased from 30 percent (30/100) among pre-EDMRT subjects to 15 percent (15/100) errors among post-EDMRT subjects. Dosage errors were the most common type of medication error. The adjusted odds ratio of discharge with intravenous antibiotic error in the post-EDMRT era was 0.39 (0.18, 0.87) compared to the pre-EDMRT era. In the adjusted model, the total number of discharge medications was associated with increased OR of discharge error. To the authors' knowledge, no other study has examined the impact of reconciliation on types and prevalence of medication errors at hospital discharge.

    Recent years have witnessed an explosion of extensive geolocated datasets related to human movement, enabling scientists to quantitatively study individual and collective mobility patterns, and to generate models that can capture and reproduce the spatiotemporal structures and regularities in human trajectories. The study of human mobility is especially important for applications such as estimating migratory flows, traffic forecasting, urban planning, and epidemic modeling. In this survey, we review the approaches developed to reproduce various mobility patterns, with the main focus on recent developments. This review can be used both as an introduction to the fundamental modeling principles of human mobility, and as a collection of technical methods applicable to specific mobility-related problems. The review organizes the subject by differentiating between individual and population mobility and also between short-range and long-range mobility. Throughout the text the description of the theory is intertwined with real-world applications.

  19. The potential of multicultural congregations in supporting social reconciliation

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Race, ethnicity and national identity are important discussions that are unfinished ecclesial business for churches in South Africa. Churches remain mono-cultural to a large extent; a significant challenge is the fact that churches still largely reflect the social divisions of a society. Although not common in South Africa, there are, at the same time, congregations that are successful at reaching across racial and cultural divides to attract new members and build social capital. This article discusses the reconciliation potential of multicultural churches in that they are able to accommodate multiple racial groups, in a society where religious life remains overwhelmingly segregated. Racial integration is a sensitive issue that has divisive potential and churches and religions in general tend to avoid the issue. Religious communities played a critical role in the transition to democracy; what is needed now is for churches to deepen this reconciliation potential.

    This article analyses the Juba peace negotiations on accountability and reconciliation. It advances a new interpretation of the Agreement on Accountability and Reconciliation, focusing on five justice features: National proceedings, restorative accountability, alternative sentencing, individual...... responsibility and forward-looking victimhood. The article argues that the nature of the agreed justice policy derives from negotiators and mediators’ pursuit of international legitimation by the ICC and its compliance constituency. This argument has implications for our understanding of the role of the ICC...... in internationally judicialised peace processes: The need for peace agreement legitimation combined with the legitimacy requirements in such peace processes structurally constitutes the ICC as metaphorically present in the negotiation room and thus akin to a third-party actor....

  1. A Quantitative Evaluation of Medication Histories and Reconciliation by Discipline

    2014-01-01

    Abstract Background/Objective: Medication reconciliation at transitions of care decreases medication errors, hospitalizations, and adverse drug events. We compared inpatient medication histories and reconciliation across disciplines and evaluated the nature of discrepancies. Methods: We conducted a prospective cohort study of patients admitted from the emergency department at our 760-bed hospital. Eligible patients had their medication histories conducted and reconciled in order by the admitting nurse (RN), certified pharmacy technician (CPhT), and pharmacist (RPh). Discharge medication reconciliation was not altered. Admission and discharge discrepancies were categorized by discipline, error type, and drug class and were assigned a criticality index score. A discrepancy rating system systematically measured discrepancies. Results: Of 175 consented patients, 153 were evaluated. Total admission and discharge discrepancies were 1,461 and 369, respectively. The average number of medications per participant at admission was 8.59 (1,314) with 9.41 (1,374) at discharge. Most discrepancies were committed by RNs: 53.2% (777) at admission and 56.1% (207) at discharge. The majority were omitted or incorrect. RNs had significantly higher admission discrepancy rates per medication (0.59) compared with CPhTs (0.36) and RPhs (0.16) (P < .001). RPhs corrected significantly more discrepancies per participant than RNs (6.39 vs 0.48; P < .001); average criticality index reduction was 79.0%. Estimated prevented adverse drug events (pADEs) cost savings were $589,744. Conclusions: RPhs committed the fewest discrepancies compared with RNs and CPhTs, resulting in more accurate medication histories and reconciliation. RPh involvement also prevented the greatest number of medication errors, contributing to considerable pADE-related cost savings. PMID:25477614

    Drug related problems (DRP) can lead to severe consequences in kidney recipients. The aim of the study was to assess the impact of the clinical pharmacist interventions on the incidence of DRP. The number of DRP were evaluated according to 3periods: Without intervention, with medication reconciliation at admission, and with medication reconciliation at admission associated with an interview with the clinical pharmacist at discharge. Patients concerned were mainly men, 55years old (median age), stage3 of CKD, transplanted for less than 3months or more than 1year, with cardiovascular risk factors and receiving an average of 9drugs/day. Among the DRP, 20% were avoidable and severe in most cases. In period1, 27.7% patients had at least 1DRP, in period2, 21.3% patients had at least 1DRP, and in period3, 17.4% of patients had at least 1DRP (P=0.03). One hundred and ten patients had medication reconciliation at admission with a mean of 0.6unintentional discrepancies per patient (omission in 81% of cases). The main drugs involved concerned the digestive-metabolic (24.5%), cardiovascular (23%), and nervous (23%) system. Sixty-eight interviews at discharge were realized and revealed self-medication habits. Our study shows that medication reconciliation at admission associated with an interview with the clinical pharmacist at discharge can help to reduce DRP in kidney recipients. Further studies are needed to confirm our results. Copyright © 2017 Société francophone de néphrologie, dialyse et transplantation. Published by Elsevier Masson SAS. All rights reserved.

    The authors examine the conflicted relationship between Orthodox Judaism and psychoanalysis. Orthodox Jewish thinkers about psychology have responded to psychoanalysis as incompatible with the practice of Orthodox Judaism. On the other hand, those psychoanalytic writers who have examined the beliefs and practices of Orthodox Jews have tended to treat these issues in a reductionistic fashion. However, the authors find possibilities for reconciliation and dialogue in the work of Aaron Rabinowitz and Moshe Halevi Spero.

  5. Evaluation of robust functions for data reconciliation in thermal systems

    Directory of Open Access Journals (Sweden)

    Regina Luana Santos de França

    2016-04-01

    Full Text Available Process variables regularly control and evaluate industrial processes. Information with gross errors may in some cases not be attenuated by function reconciliation and change the calculation of process balance, leading optimization results towards non-feasible regions or to optimal sites. A promising alternative for reconciling functions is the use of robust functions. Current paper considers the above scenario and evaluates the fitness of some robust functions in solving in steady state chemical processes data reconciliation problems represented by linear and nonlinear systems in the presence of gross errors. Traditional Cauchy, Fair, Contaminated Normal and Logistic robust functions are used in the reconciliation problem where their estimates are compared to those obtained with the use of the latest features, such as New Target and Alarm. Rates for gross errors in tests were limited between 4 and 10σ of the measured current and elaborated a region of outliers. Results showed that New Target and Alarm functions are different from the others as the magnitude of the gross error increases, tending towards true rates specified by set point.

  6. An African Perspective on Peace Education: Ubuntu Lessons in Reconciliation

    Science.gov (United States)

    Murithi, Tim

    2009-05-01

    This essay examines the value of educating for peace. It does this through a consideration of the African cultural world-view known as ubuntu, which highlights the essential unity of humanity and emphasises the importance of constantly referring to the principles of empathy, sharing and cooperation in efforts to resolve our common problems. The essay is not based on field research, but rather on a discussion of the issues pertaining to ubuntu and peace education. The discussion focuses on how Desmond Tutu utilised the principles of ubuntu during his leadership of the South African Truth and Reconciliation Commission. It also outlines the five stages of the peacemaking process found among ubuntu societies: acknowledging guilt; showing remorse and repenting; asking for and giving forgiveness; and paying compensation or reparations as a prelude to reconciliation. Potential lessons for educating for peace and reconciliation are highlighted based on the premise that the ubuntu approach to human relationship-building can offer an example to the world.

    International Nuclear Information System (INIS)

    Quang, A. Tran; Chares, R.

    2012-01-01

    With the long term operation of nuclear power plants, decisions to replace or repair should be optimized from an economical, human resource and safety point of view. In that frame, the operation requires a continuous inspection and testing of systems in order to detect degradations and failures at an early stage. Nevertheless, in spite of the fact that such assiduous vigilance ensures safety, it is not optimized in terms of man power and maintenance costs. Preventive strategies show the same types of drawbacks. On top of that, these maintenance procedures rely on process measurements which accuracy, availability and reliability cannot always be ensured. The present paper introduces a new approach to the maintenance management of ageing installations and suggests a method that overcomes the actual drawbacks. The Reconciliation and Validation of data (DVR) is an advanced and innovative technology that relies on process data statistics, thermodynamic and on-site process knowledge. Benefits of real-time applications are also presented. (author)

    Full Text Available Objective: The objective of this study is to conduct a review of pertinent literature, assess pharmacy involvement in medication reconciliation, and offer insight into best practices for hospitals to implement and enhance their medication reconciliation programs. Method: Pharmacists in hospitals nationwide were asked to complete an anonymous survey via the American College of Clinical Pharmacy online database. The multiple choice survey analyzed the roles that healthcare professionals play in medication reconciliation programs at hospitals. Results: Of the survey responses received, 32/91 (35% came from pharmacists at hospitals with a pharmacy-led medication reconciliation program. Of these pharmacy-led programs, 17/32 (53% have a dedicated pharmacist or pharmacy staff to perform medication reconciliation. Conclusion: A comprehensive review of literature suggests that pharmacy involvement has the potential to reduce medication reconciliation errors and may improve patient satisfaction. Focused, full-time medication reconciliation pharmacists can help hospitals save time and money, improve outcomes, and meet higher standards issued by the Joint Commission. Data obtained in this study show the extent to which pharmacists contribute to achieving these goals in healthcare systems nationwide. This baseline study provides a strong case for hospitals to implement a pharmacy-led medication reconciliation program.

    Movement into or out of hospital is a vulnerable period for medication safety. Reconciling the medication a patient is using before admission with the medication prescribed on discharge, and documenting any changes (medication reconciliation) is recommended to improve safety. The aims of the study were to investigate the factors contributing to medication reconciliation on discharge, and identify the prevalence of non-reconciliation.

    Medication reconciliation is a basic principle of good medicines management. With the establishment of the National Acute Medicines Programme in Ireland, medication reconciliation has been mandated for all patients at all transitions of care. The clinical pharmacist is widely credited as the healthcare professional that plays the most critical role in the provision of medication reconciliation services.

    It is important to recognize the distinction between risk assessment and its components which include risk analysis, perspectives study, and decision analysis. Divergence of opinion within the scientific community as well as the public at large is a characteristic of issues related to nuclear power. The divergent opinions can largely be characterized as either optimistic or pessimistic in nature. Reconciliation of divergent viewpoints presents some difficult challenges. It is doubtful that issues which have an emotional or philosophical basis can be resolved through technical efforts. Public education on the technical issues might prove helpful

    2012-03-01

    Full Text Available In the 4ᵗʰcentury, when a time of freedom of Christian religion came, liturgical rites began to develop rapidly and this also applied to the liturgy of penance. At the time for heavy publicly known sins one needed to do public penance. On Ash Wednesday, one would be admitted within the group of penitents, and then on Maundy Thursday reconciliation took place. The first rites of such a celebration, comprised in Sacramentarium gelasianum from the 7ᵗʰ century, in later periods would become even more elaborate in the medieval pontificals. The Roman pontifical of 1596 took over the rites from the Pontifical of Durandus. The liturgy of public penitents lasted in certain places up to the 18ᵗʰ century. It was solemnly performed and presided over by a bishop, in the presence of the clergy, liturgical service and the faithful. In the rite published after the Second Vatican Council there is no mention of either public penitents or of the accompanying reconciliation rites.

  7. A comparative evaluation of genome assembly reconciliation tools.

    Alhakami, Hind; Mirebrahim, Hamid; Lonardi, Stefano

    2017-05-18

    The majority of eukaryotic genomes are unfinished due to the algorithmic challenges of assembling them. A variety of assembly and scaffolding tools are available, but it is not always obvious which tool or parameters to use for a specific genome size and complexity. It is, therefore, common practice to produce multiple assemblies using different assemblers and parameters, then select the best one for public release. A more compelling approach would allow one to merge multiple assemblies with the intent of producing a higher quality consensus assembly, which is the objective of assembly reconciliation. Several assembly reconciliation tools have been proposed in the literature, but their strengths and weaknesses have never been compared on a common dataset. We fill this need with this work, in which we report on an extensive comparative evaluation of several tools. Specifically, we evaluate contiguity, correctness, coverage, and the duplication ratio of the merged assembly compared to the individual assemblies provided as input. None of the tools we tested consistently improved the quality of the input GAGE and synthetic assemblies. Our experiments show an increase in contiguity in the consensus assembly when the original assemblies already have high quality. In terms of correctness, the quality of the results depends on the specific tool, as well as on the quality and the ranking of the input assemblies. In general, the number of misassemblies ranges from being comparable to the best of the input assembly to being comparable to the worst of the input assembly.

  8. Population and development: controversy and reconciliation.

    Kelley, A C

    1985-01-01

    This paper evaluates the 2 most important antinatalist arguments the have dominated the population debate over the last 25 years, drawing heavily on 3 1984 studies -- land and resource scarcity and saving and investment. The extent to which these arguments have successfully included the indirect effects of population growth on an economy in order to determine the net impact of population is assessed an emerging revisionist interpretation of the role of population in development is discussed. It is believed that on scientific grounds, and focusing primarily on economic impact, neither the arguments nor the various models used to support the antinatalist position sufficiently support the strength of the general conclusion that population growth exerts a strong adverse impact on the economy. Population growth reveals sooner the symptoms of underlying problems, but many of the solutions are to be found in areas other than altering the rate of population growth. Population growth is viewed less as a cause of development problems and more as an agent that pushes more fundamental problems to the forefront. Empirical evidence concerning nonrenewable resource constraints is not sufficient to make any strong conclusion about the impact of rapid population growth. With regard to food, the problem is more one of unrealized potential for increasing agricultural output and of the distribution of income than of diminishing returns to land. The results of economic research have failed to provide substantial and convincing empirical evidence to support the strong antinatalist concern about the adverse effect rapid population growth has on savings and investment. Authors of recent literature reviews deemphasized this impact. A revisionist interpretation deemphasizes some of the traditional" hypothesized direct influence of population and assigns population the role of an accomplice in contrast to the leading role of villain in the development story. To this list is added the

    Full Text Available Truth commissions and trials have been applauded as the way to move on from a violent past. Yet, some post-conflict societies managed to move toward reconciliation without the presence, or the effective presence of such formal institutions. This article discusses a number of lessons learned from Maluku, where reconciliation took the interdependence path. Taking on an interpretive, emic approach, it elaborates on the sites and mechanisms of interpendence. It argues that interdependence can be as viable as truth and justice procedures in bringing about reconciliation.

    Full Text Available Testifying to the gap in fundamental research on positive intergroup outcomes, we investigated reconciliation attitudes in a non-violent intergroup context (i.e., the linguistic conflict in Belgium. By incorporating both important predictors of negative outgroup attitudes (i.e., individual differences in rigid cognitive styles and authoritarian ideologies, and important predictors of reconciliation (i.e., intergroup emotions, we aimed to contribute to a more comprehensive theoretical framework for the analysis of intergroup relations. We recruited one Flemish ('N' = 310 and one Walloon ('N' = 365 undergraduate students sample to test the proposed model. Structural equation analyses with maximum likelihood estimation were conducted using the Lavaan package. In both samples, similar patterns were found. More in particular, the need for cognitive closure appeared to be the basic predictor of right-wing attitudes (i.e., right-wing authoritarianism and social dominance orientation and essentialist thinking, which were then associated with less outgroup empathy and trust, and more outgroup anger. Furthermore, outgroup trust and empathy were positively related to reconciliation. Interestingly, some differences between the Flemish and Walloon sample were found, such as the direct effects of need for closure and social dominance orientation in the first sample, and the non-significant effects of essentialism in the latter sample. Considering the ongoing public and political debate about the linguistic conflict in Belgium, these findings shed a new light on how individual differences relate to specific outgroup emotions, and how these are associated with important intergroup outcomes in the face of intergroup conflict.

The cities’ demographic picture has been changed, as well as the ethnic and social structure. That is why we have been conducting our activities in the community reconciliation process in rural and urban areas, applying different methods of work. Our activities were aimed at all national and social groups. Our association’s target group is women. With our activities, we are trying to raise public awareness about the women’s issues and to find solutions to those problems. We have worked on key problems that arose as a consequence of war experiences, which were brought forward by the women. We are trying to achieve an insight into the problems that are common to the women from different social and ethnic groups and, by attempting to solve them; we work on conflict resolution and transformation.

    2012-09-01

    Whether employed and nonemployed mothers of children with intellectual disability (ID) have different experiences with reconciliation between care and work has rarely been explored. A survey was conducted in a county in Taiwan and 487 mothers aged younger than 65 and having a child with ID were interviewed face to face at their homes to explore whether there are different factors related to the reconciliation between care and work among employed and nonemployed mothers. Except for the common ground of mothers' health and care demands, logistic regression revealed work flexibility and care support were important for employed mothers. In contrast, the success of reconciliation for nonemployed mothers was determined by their individual characteristics (i.e., age, marital status, family income). Reconciliation policies for mothers with different employment statuses need to use different strategies.

    Cultivating a spirituality of reconciliation would mean making reconciliation a lifestyle, rather than a series of strategies, pro- grammes or initiatives, yet remaining concrete, practical, mea- surable and accountable.   The church’s mission is primarily to proclaim the good news of God’s Kingdom that is already here, but not yet fully here and therefore still to come. This proclamation is the message of reconciliation between God, others and the self, and anticipates the unity of all creation in Jesus Christ.   The resources given to the church to fulfil this apostolic ministry include prophecy, evangelism, pastoral care and teaching, as well as its liturgical and sacramental life, its ministry of pre- sence, its people and its commitment to social justice.

    Medication discrepancies occur in 70% of hospital patients, especially during discharge. In community settings, bag medication reconciliation events have demonstrated effectiveness in evaluating current medication use and identifying medication discrepancies. A bag medication reconciliation process was implemented in the hospital setting to decrease medication discrepancies by encouraging evaluation of medication adherence, side effects, and monitoring at posthospitalization follow-up. After implementation, a 7% decrease in reportable errors was noted.

      This article, while not uncritical of the Commission, is generally positive about its contribution both in attempting to deal with the past, and in building a democratic, human rights and restorative justice culture based on the rule of law. It examines the definitions of reconciliation that emerged during the Commission in the light of a Christian definition where reconciliation is seen to be between God, others and self, and involves integration with the human community. This integration involves taking responsibility for the past, confession and repentance, forgiving and being forgiven, making restitution where possible, ongoing transformation in the present and hope for the future.

    Stagnation in hospitals' adoption of data integration functionalities coupled with reduction in the number of operational health information exchanges could become a significant impediment to hospitals' adoption of 3 critical capabilities: electronic health information exchange, interoperability, and medication reconciliation, in which electronic systems are used to assist with resolving medication discrepancies and improving patient safety. Against this backdrop, we assessed the relationships between the 3 capabilities.We conducted an observational study applying partial least squares-structural equation modeling technique to 27 variables obtained from the 2013 American Hospital Association annual survey Information Technology (IT) supplement, which describes health IT capabilities.We included 1330 hospitals. In confirmatory factor analysis, out of the 27 variables, 15 achieved loading values greater than 0.548 at P building blocks of the 3 capabilities. Subsequent path analysis showed a significant, positive, and cyclic relationship between the capabilities, in that decreases in the hospitals' adoption of one would lead to decreases in the adoption of the others.These results show that capability for high quality medication reconciliation may be impeded by lagging adoption of interoperability and health information exchange capabilities. Policies focused on improving one or more of these capabilities may have ancillary benefits.

    Component degradation modeling being developed to understand the aging process can have many applications with potential advantages. Previous work has focused on developing the basic concepts and mathematical development of a simple degradation model. Using this simple model, times of degradations and failures occurrences were analyzed for standby components to detect indications of aging and to infer the effectiveness of maintenance in preventing age-related degradations from transforming to failures. Degradation modeling approaches can have broader applications in aging studies and in this paper, we discuss some of the extensions and applications of degradation modeling. The application and extension of degradation modeling approaches, presented in this paper, cover two aspects: (1) application to a continuously operating component, and (2) extension of the approach to analyze degradation-failure rate relationship. The application of the modeling approach to a continuously operating component (namely, air compressors) shows the usefulness of this approach in studying aging effects and the role of maintenance in this type component. In this case, aging effects in air compressors are demonstrated by the increase in both the degradation and failure rate and the faster increase in the failure rate compared to the degradation rate shows the ineffectiveness of the existing maintenance practices. Degradation-failure rate relationship was analyzed using data from residual heat removal system pumps. A simple linear model with a time-lag between these two parameters was studied. The application in this case showed a time-lag of 2 years for degradations to affect failure occurrences. 2 refs

    Sheikh Khalifa Medical City (SKMC) in Abu Dhabi is the main tertiary care referral hospital in the United Arab Emirates (UAE) with 560 bed capacity that is fully occupied most of the time. SKMC senior management has made a commitment to make quality and patient safety a top priority. Our governing body Abu Dhabi Health Services Company has identified medication reconciliation as a critical patient safety measure and key performance indicator (KPI). The medication reconciliation electronic form a computerized decision support tool was introduced to improve medication reconciliation compliance on transition of care at admission, transfer and discharge of patients both in the inpatient and outpatient settings. In order to improve medication reconciliation compliance a multidisciplinary task force team was formed and led this quality improvement project. The purpose of this publication is to indicate the quality improvement interventions implemented to enhance compliance with admission medication reconciliation and the outcomes of those interventions. We chose to conduct the pilot study in general medicine as it is the busiest department in the hospital, with an average of 390 patients admitted per month during the study period. The study period was from April 2014 till October 2015 and a total of 8576 patients were evaluated. The lessons learned were disseminated throughout the hospital. Our aim was to improve admission medication reconciliation compliance using the electronic form in order to ensure patient safety and reduce preventable harm in terms of medication errors. Admission medication reconciliation compliance improved in general medicine from 40% to above 85%, and this improvement was sustained for the last four months of the study period. PMID:27822371

    Directory of Open Access Journals (Sweden)

    Jörg Benndorf

    2015-08-01

    Full Text Available This contribution presents an innovative and integrated framework for real-time-process reconciliation and optimization (RTRO in large continuous open pit coal mines. RTRO-Coal is currently developed, validated, tested and implemented as part of a multi-national multi-partner European Union funded R&D project. The key concept is to promote a shift in paradigm from intermittent discontinuous to a continuous process monitoring and quality management system in large scale coal mining operations. The framework is based on a real-time feedback control loop linking online data acquired during extraction rapidly with a sequentially up-datable resource model. The up-to-date model is integrated with a real-time optimization of short-term sequencing and production control decisions. Improved decisions are expected to lead to increased resource-and process efficiency and support a sustainable extraction of natural resources. This contribution introduces to the framework, discusses main building blocks and illustrates the value added by the means of selected examples.

  18. Slovenian Anti-Semitism, Buried Alive in the Ideology of Slovenian National Reconciliation

    Directory of Open Access Journals (Sweden)

    Irena Šumi

    2015-06-01

    Full Text Available Following 1991, the ideology of national reconciliation as formulated by philosopher Spomenka Hribar during the 1980s became part and parcel of the Slovenian postsocialism transition. The interpretation of the confessional clash on the occupied Slovenian soil during WWII that the ideology adopts had, and still has, numerous legal, political, cultural and social consequences. In accord with the historical essence of the Slovenian biopolitics that insists on pseudo-biological understandings of social continuities, the reconciliation ideology affirms a specific type of historic revisionism whose central point is a total silence on pre-war confessional and ideological antiSemitism on the part of the then-Slovenian Catholic Church and its close ally, the Slovenian People’s Party. The ideology of reconciliation likewise totally suppresses the wartime persecution of Slovenian Jews in the hands of collaborationist authorities, as well as post-war programmatic anti-Semitism of the revolutionary authorities. With this complete omission, the reconciliation idea not only entirely missed its declared goal, to “accept our history,” but decontextualised the history itself, and with it, distorted it. Although the idea of reconciliation in this ideational framework is a glaring political failure, it has, paradoxically, sucessfully established itself as the diacritic between the closely complementary transition political left and right even as both are, since 1991, entirely devoted to neoliberal ideologies and politics.

  19. Dialogical inquiry as an instrument of the reconciliation of conflict in the hands of Christian leaders

    C.J. Hugo

    2010-07-01

    Full Text Available The apartheid system caused deep rifts in South African society, and even following the dawn of democracy, society in South Africa continues to struggle with violence and conflict, ethnic differences, mass action and poverty. Christian leaders have an important part to play in conflict resolution. Conflict management in organisations incorporates negotiation as a means of conflict resolution. A number of approaches to conflict resolution contribute to this approach; these include forcing, avoiding, accommodating, compromising and collaborating. Christian leaders, however, favour reconciliation as a means of resolving conflict. A Christian approach to conflict resolution needs to take cognisance of the existential aspect of conflict. Examples of such approaches are those of Dreyer, who speaks of reconciliation as a dilemma for forgiveness, and Kistner, who explores the way in which the use of narratives rather than reallife stories in the Truth and Reconciliation Commission reduced the severity of trauma. The social construction of trauma in “Mamelodi” by Brigid Hess, which presents a shift from forgiveness to a journey taken along with the perpetrators, and the belief of Desmond Tutu in the healing brought about by the ubuntu philosophy, are evaluated here as being detrimental to reconciliation. Based on the examples cited, an approach to conflict resolution entailing a clear integration of the biblical approach to reconciliation and dialogical inquiry (DI is proposed as an appropriate intervention approach for Christian leaders. The present contribution is offered from within the discipline of Practical Theology, with a focus on Pastoral Counseling.

    2005-01-01

    Aeroassist is a broad category of advanced transportation technology encompassing aerocapture, aerobraking, aeroentry, precision landing, hazard detection and avoidance, and aerogravity assist. The eight destinations in the Solar System with sufficient atmosphere to enable aeroassist technology are Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Saturn's moon Titan. Engineering-level atmospheric models for five of these targets - Earth, Mars, Titan, Neptune, and Venus - have been developed at NASA's Marshall Space Flight Center. These models are useful as tools in mission planning and systems analysis studies associated with aeroassist applications. The series of models is collectively named the Global Reference Atmospheric Model or GRAM series. An important capability of all the models in the GRAM series is their ability to simulate quasi-random perturbations for Monte Carlo analysis in developing guidance, navigation and control algorithms, for aerothermal design, and for other applications sensitive to atmospheric variability. Recent example applications are discussed.

    A wide range of mathematical techniques have been applied to artificial intelligence problems and some techniques have proved more suitable than others for certain types of problem. We formally define a mathematical model which incorporates some of these successful techniques and we discuss its intrinsic properties. Universal applicability of the model is demonstrated through specific applications to problems drawn from rule-based systems, digital hardware design and constraint satisfaction networks. We also give indications of potential applications to other artificial intelligence problems, including knowledge engineering.

    2012-08-01

    Full Text Available The Truth and Reconciliation Commission (TRC of Canada was established to uncover and acknowledge the injustices that took place in Indian residential schools and, in doing so, to pave the way to reconciliation. However, the TRC does not define reconciliation or how we would know it when (and if we get there, thus stirring a debate about what it could mean. This article examines two theories that may potentially be relevant to the TRC’s work: Charles Taylor’s theory of recognition and Nancy Fraser’s tripartite theory of justice. The goal is to discover what each theory contributes to our understanding of the harms that Indigenous peoples suffered in residential schools, as well as in the broader colonial project, and how to address these harms appropriately.

  10. Role of Social Knowledge Networking technology in facilitating meaningful use of Electronic Health Record medication reconciliation.

    Rangachari, Pavani

    2016-06-01

    Despite the federal policy impetus towards EHR Medication Reconciliation, hospital adherence has lagged for one chief reason; low physician engagement, which in turn emanates from lack of consensus in regard to which physician is responsible for managing a patient's medication list, and the importance of medication reconciliation as a tool for improving patient safety and quality of care. The Technology-in-Practice (TIP) framework stresses the role of human action in enacting structures of technology use or "technologies-in-practice." Applying the TIP framework to the EHR Medication Reconciliation context, helps frame the problem as one of low physician engagement in performing EHR Medication Reconciliation, translating to limited-use-EHR-in-practice. Concurrently, the problem suggests a hierarchical network structure, reflecting limited communication among hospital administrators and clinical providers on the importance of EHR Medication Reconciliation in improving patient safety. Integrating the TIP literature with the more recent knowledge-in-Practice (KIP) literature suggests that EHR-in-practice could be transformed from "limited use" to "meaningful use" through the use of Social Knowledge Networking (SKN) Technology to create new social network structures, and enable engagement, learning, and practice change. Correspondingly, the objectives of this paper are to: 1) Conduct a narrative review of the literature on "technology use," to understand how technologies-in-practice may be transformed from limited use to meaningful use; 2) Conduct a narrative review of the literature on "organizational change implementation," to understand how changes in technology use could be successfully implemented and sustained in a healthcare organizational context; and 3) Apply lessons learned from the narrative literature reviews to identify strategies for the meaningful use and successful implementation of EHR Medication Reconciliation technology.

    Many applications have irregular behavior --- non-uniform input data, input-dependent solvers, irregular memory accesses, unbiased branches --- that cannot be captured using today's automated performance modeling techniques. We describe new hierarchical critical path analyses for the \\Palm model generation tool. To create a model's structure, we capture tasks along representative MPI critical paths. We create a histogram of critical tasks with parameterized task arguments and instance counts. To model each task, we identify hot instruction-level sub-paths and model each sub-path based on data flow, instruction scheduling, and data locality. We describe application models that generate accurate predictions for strong scaling when varying CPU speed, cache speed, memory speed, and architecture. We present results for the Sweep3D neutron transport benchmark; Page Rank on multiple graphs; Support Vector Machine with pruning; and PFLOTRAN's reactive flow/transport solver with domain-induced load imbalance.

    2006-01-01

    A classical queueing model consists of three parts - arrival process, service process, and queue discipline. However, a vacation queueing model has an additional part - the vacation process which is governed by a vacation policy - that can be characterized by three aspects: 1) vacation start-up rule; 2) vacation termination rule, and 3) vacation duration distribution. Hence, vacation queueing models are an extension of classical queueing theory. Vacation Queueing Models: Theory and Applications discusses systematically and in detail the many variations of vacation policy. By allowing servers to take vacations makes the queueing models more realistic and flexible in studying real-world waiting line systems. Integrated in the book's discussion are a variety of typical vacation model applications that include call centers with multi-task employees, customized manufacturing, telecommunication networks, maintenance activities, etc. Finally, contents are presented in a "theorem and proof" format and it is invaluabl...

  13. Polymer networks: Modeling and applications

    Masoud, Hassan

    Polymer networks are an important class of materials that are ubiquitously found in natural, biological, and man-made systems. The complex mesoscale structure of these soft materials has made it difficult for researchers to fully explore their properties. In this dissertation, we introduce a coarse-grained computational model for permanently cross-linked polymer networks than can properly capture common properties of these materials. We use this model to study several practical problems involving dry and solvated networks. Specifically, we analyze the permeability and diffusivity of polymer networks under mechanical deformations, we examine the release of encapsulated solutes from microgel capsules during volume transitions, and we explore the complex tribological behavior of elastomers. Our simulations reveal that the network transport properties are defined by the network porosity and by the degree of network anisotropy due to mechanical deformations. In particular, the permeability of mechanically deformed networks can be predicted based on the alignment of network filaments that is characterized by a second order orientation tensor. Moreover, our numerical calculations demonstrate that responsive microcapsules can be effectively utilized for steady and pulsatile release of encapsulated solutes. We show that swollen gel capsules allow steady, diffusive release of nanoparticles and polymer chains, whereas gel deswelling causes burst-like discharge of solutes driven by an outward flow of the solvent initially enclosed within a shrinking capsule. We further demonstrate that this hydrodynamic release can be regulated by introducing rigid microscopic rods in the capsule interior. We also probe the effects of velocity, temperature, and normal load on the sliding of elastomers on smooth and corrugated substrates. Our friction simulations predict a bell-shaped curve for the dependence of the friction coefficient on the sliding velocity. Our simulations also illustrate

  14. A fast method for calculating reliable event supports in tree reconciliations via Pareto optimality.

    Given a gene and a species tree, reconciliation methods attempt to retrieve the macro-evolutionary events that best explain the discrepancies between the two tree topologies. The DTL parsimonious approach searches for a most parsimonious reconciliation between a gene tree and a (dated) species tree, considering four possible macro-evolutionary events (speciation, duplication, transfer, and loss) with specific costs. Unfortunately, many events are erroneously predicted due to errors in the input trees, inappropriate input cost values or because of the existence of several equally parsimonious scenarios. It is thus crucial to provide a measure of the reliability for predicted events. It has been recently proposed that the reliability of an event can be estimated via its frequency in the set of most parsimonious reconciliations obtained using a variety of reasonable input cost vectors. To compute such a support, a straightforward but time-consuming approach is to generate the costs slightly departing from the original ones, independently compute the set of all most parsimonious reconciliations for each vector, and combine these sets a posteriori. Another proposed approach uses Pareto-optimality to partition cost values into regions which induce reconciliations with the same number of DTL events. The support of an event is then defined as its frequency in the set of regions. However, often, the number of regions is not large enough to provide reliable supports. We present here a method to compute efficiently event supports via a polynomial-sized graph, which can represent all reconciliations for several different costs. Moreover, two methods are proposed to take into account alternative input costs: either explicitly providing an input cost range or allowing a tolerance for the over cost of a reconciliation. Our methods are faster than the region based method, substantially faster than the sampling-costs approach, and have a higher event-prediction accuracy on

    Full Text Available Application layer firewalls protect the trusted area network against information security risks. However, firewall performance may affect user experience. Therefore, performance analysis plays a significant role in the evaluation of application layer firewalls. This paper presents an analytic model of the application layer firewall, based on a system analysis to evaluate the capability of the firewall. In order to enable users to improve the performance of the application layer firewall with limited resources, resource allocation was evaluated to obtain the optimal resource allocation scheme in terms of throughput, delay, and packet loss rate. The proposed model employs the Erlangian queuing model to analyze the performance parameters of the system with regard to the three layers (network, transport, and application layers. Then, the analysis results of all the layers are combined to obtain the overall system performance indicators. A discrete event simulation method was used to evaluate the proposed model. Finally, limited service desk resources were allocated to obtain the values of the performance indicators under different resource allocation scenarios in order to determine the optimal allocation scheme. Under limited resource allocation, this scheme enables users to maximize the performance of the application layer firewall.

    It can often be questioned how well you can rely on process measurements, as most processes in bio-fuelled power plants are changing conditions continuously, and then also the measured values will follow the process. Heat exchangers are fouled; sensors are drifting; the fuel quality is varying without your knowledge e.g. with respect to moisture and ash content etc. The goal with this project is to improve the quality assurance with respect to sensors as well as the process performance as such. This is done by using the physical knowledge we have on the process and which is transferred into a simulation model. This is used to correlate different sensor measurements to each other. This is called data-reconciliation and has earlier been tested (Varmeforsk 2003) for steady state conditions by using material balances. In this project we want to take the methodology a bit further by considering process dynamics as well and by following the deviation between model predictions for different sensors to the actual measurements. By doing this, faults can be detected earlier than otherwise and more information can be acquired from the process. Information achieved by the proposed method can primarily be utilized by process operators and process engineers at power plants and in e.g. pulp and paper industry. Minute sampled data from the process have been used from the process data base during a two week period. During this period the process has been operated relatively stable during some periods and with a significant change in the conditions during a 12 hour period when the capacity was reduced to approximately 60% of the normal maximum capacity. First a Modellica model was built and verified towards process data. In parallel a more advanced simulation model made in APROS with an interface made by Process Vision has been used. The deviation between the measured and simulated variables has been calculated for a number of variables. We can see a significant deviation between

    Bailey, Larissa; MacKenzie, Darry I.; Nichols, James D.

    2013-01-01

    Summary: The past decade has seen an explosion in the development and application of models aimed at estimating species occurrence and occupancy dynamics while accounting for possible non-detection or species misidentification. We discuss some recent occupancy estimation methods and the biological systems that motivated their development. Collectively, these models offer tremendous flexibility, but simultaneously place added demands on the investigator. Unlike many mark–recapture scenarios, investigators utilizing occupancy models have the ability, and responsibility, to define their sample units (i.e. sites), replicate sampling occasions, time period over which species occurrence is assumed to be static and even the criteria that constitute ‘detection’ of a target species. Subsequent biological inference and interpretation of model parameters depend on these definitions and the ability to meet model assumptions. We demonstrate the relevance of these definitions by highlighting applications from a single biological system (an amphibian–pathogen system) and discuss situations where the use of occupancy models has been criticized. Finally, we use these applications to suggest future research and model development.

    To identify the incidence of federally imposed penalties for violations of the Consolidated Omnibus Reconciliation Act (COBRA). Under the Freedom of Information Act, we retrieved a copy of any document related to fines imposed on, settlements made by, or litigation against physicians or hospitals as a result of COBRA violations from the Office of the Inspector General. Under a separate inquiry, also under the Freedom of Information Act, we requested and received from the central office of the Health Care Financing Administration the National Composite Log showing the status of all complaint investigations pursuant to COBRA since the inception of the law. One thousand seven hundred fifty-seven complaint investigations were authorized. Of the 1,729 investigations completed, 412 (24%) were found to be out of compliance with federal regulations. Of these, 27 cases resulted in fines imposed on hospitals. These fines ranged from $1,500 to $150,000 with a mean of $33,917, a median of $25,000, and standard deviation of $35,899. The six fines that were imposed against physicians ranged in value from $2,500 to $20,000 with a mean of $8,500, a median of $7,500, and an SD of $8,612. Seven hospitals but no physicians were terminated from the Medicare program for COBRA violations. The incidence of federally imposed penalties for COBRA violations is low given the multitude of patient transfers that have occurred since the enactment of COBRA. The growing concern regarding this issue may be related to current litigation efforts to broaden the scope and applications of these laws.

    Over the past decade, the US Department of Energy (DOE) and other agencies have faced increasing scrutiny for a wide range of environmental issues related to past and current practices. A number of large-scale applications have been undertaken that required analysis of large numbers of potential environmental issues over a wide range of environmental conditions and contaminants. Several of these applications, referred to here as large-scale applications, have addressed long-term public health risks using a holistic approach for assessing impacts from potential waterborne and airborne transport pathways. Multimedia models such as the Multimedia Environmental Pollutant Assessment System (MEPAS) were designed for use in such applications. MEPAS integrates radioactive and hazardous contaminants impact computations for major exposure routes via air, surface water, ground water, and overland flow transport. A number of large-scale applications of MEPAS have been conducted to assess various endpoints for environmental and human health impacts. These applications are described in terms of lessons learned in the development of an effective approach for large-scale applications

    Over the last 30 years statistical algorithms have been developed to analyse datasets that have a hierarchical/multilevel structure. Particularly within developmental and educational psychology these techniques have become common where the sample has an obvious hierarchical structure, like pupils nested within a classroom. We describe two areas beyond the basic applications of multilevel modelling that are important to psychology: modelling the covariance structure in longitudinal designs and using generalized linear multilevel modelling as an alternative to methods from signal detection theory (SDT). Detailed code for all analyses is described using packages for the freeware R.

    This book presents in-depth surveys and systematic discussions on models, algorithms and applications for link mining. Link mining is an important field of data mining. Traditional data mining focuses on 'flat' data in which each data object is represented as a fixed-length attribute vector. However, many real-world data sets are much richer in structure, involving objects of multiple types that are related to each other. Hence, recently link mining has become an emerging field of data mining, which has a high impact in various important applications such as text mining, social network analysi

  3. Application of Improved Radiation Modeling to General Circulation Models

    2011-04-07

    This research has accomplished its primary objectives of developing accurate and efficient radiation codes, validating them with measurements and higher resolution models, and providing these advancements to the global modeling community to enhance the treatment of cloud and radiative processes in weather and climate prediction models. A critical component of this research has been the development of the longwave and shortwave broadband radiative transfer code for general circulation model (GCM) applications, RRTMG, which is based on the single-column reference code, RRTM, also developed at AER. RRTMG is a rigorously tested radiation model that retains a considerable level of accuracy relative to higher resolution models and measurements despite the performance enhancements that have made it possible to apply this radiation code successfully to global dynamical models. This model includes the radiative effects of all significant atmospheric gases, and it treats the absorption and scattering from liquid and ice clouds and aerosols. RRTMG also includes a statistical technique for representing small-scale cloud variability, such as cloud fraction and the vertical overlap of clouds, which has been shown to improve cloud radiative forcing in global models. This development approach has provided a direct link from observations to the enhanced radiative transfer provided by RRTMG for application to GCMs. Recent comparison of existing climate model radiation codes with high resolution models has documented the improved radiative forcing capability provided by RRTMG, especially at the surface, relative to other GCM radiation models. Due to its high accuracy, its connection to observations, and its computational efficiency, RRTMG has been implemented operationally in many national and international dynamical models to provide validated radiative transfer for improving weather forecasts and enhancing the prediction of global climate change.

    2013-01-01

    Stochastic biomathematical models are becoming increasingly important as new light is shed on the role of noise in living systems. In certain biological systems, stochastic effects may even enhance a signal, thus providing a biological motivation for the noise observed in living systems. Recent advances in stochastic analysis and increasing computing power facilitate the analysis of more biophysically realistic models, and this book provides researchers in computational neuroscience and stochastic systems with an overview of recent developments. Key concepts are developed in chapters written by experts in their respective fields. Topics include: one-dimensional homogeneous diffusions and their boundary behavior, large deviation theory and its application in stochastic neurobiological models, a review of mathematical methods for stochastic neuronal integrate-and-fire models, stochastic partial differential equation models in neurobiology, and stochastic modeling of spreading cortical depression.

    1994-11-01

    During the period beginning November 1991 and ending September 1992, a series of tests were conducted at Foster Wheeler Development Corporation in a fluidized-bed coal carbonizer to determine its performance characteristics. The carbonizer was operated for 533 hours in a jetting fluidized-bed configuration during which 36 set points (steady-state periods) were achieved. Extensive data were collected on the feed and product stream compositions, heating values, temperatures, and flow rates. With these data, elemental and energy balances were computed to evaluate and confirm accuracy of the data. The carbonizer data were not as self-consistent as could be desired (balance closure imperfection). A software package developed by Science Ventures, Inc., of California, called BALAID, was used to reconcile the carbonizer data; the details of the reconciliation have been given in Volume 1 of this report. The reconciled data for the carbonizer were rigorously analyzed, correlations were developed, and the model was updated accordingly. The model was then used in simulating each of the 36 steady-state periods achieved in the pilot plant. The details are given in this Volume one. This Volume 2 provides details of the carbonizer data reconciliation.

  9. Using Reinterview and Reconciliation Methods to Design and Evaluate Survey Questions

    2008-06-01

    Full Text Available Conducting reinterviews is an effective method to estimate and reduce response errors in interview surveys. As part of the School Health Policies and Programs Study 2000 (SHPPS, RTI used reinterview methods to assist in designing and evaluating survey questions. Reinterviews were conducted in the field test with selected respondents to identify discrepancies between the original interviews and reinterviews. Reconciliation interviews were then conducted to determine the reasons for the discrepancies in terms of comprehension, recall, encoding, response options, or other problems. In this paper, we describe the design of the reinterview and reconciliation study and discuss the implications of using these methods for questionnaire design and evaluation, specifically in comparison to cognitive interviewing.

    Full Text Available Gender Mainstreaming (GM was introduced by the European Union (EU in 1997, as a strategy to achieve gender equality in all policy areas. Yet, European countries greatly diverge in their progress of implementation. We investigate the role GM played in Romanian and German policies aimed at achieving work-family reconciliation, using concepts from feminist policy analysis. Our analysis shows that pre-existing policies and discourse, the economic situation, as well as the relationship with the EU have shaped and impeded the implementation process of GM in both countries. While Germany slowly moves towards more egalitarian policies, GM as label and strategy did not succeed. In Romania, GM has only impacted work and family reconciliation indirectly through EU legislation.

    1986-01-01

    The subject of modelling and application of stochastic processes is too vast to be exhausted in a single volume. In this book, attention is focused on a small subset of this vast subject. The primary emphasis is on realization and approximation of stochastic systems. Recently there has been considerable interest in the stochastic realization problem, and hence, an attempt has been made here to collect in one place some of the more recent approaches and algorithms for solving the stochastic realiza­ tion problem. Various different approaches for realizing linear minimum-phase systems, linear nonminimum-phase systems, and bilinear systems are presented. These approaches range from time-domain methods to spectral-domain methods. An overview of the chapter contents briefly describes these approaches. Also, in most of these chapters special attention is given to the problem of developing numerically ef­ ficient algorithms for obtaining reduced-order (approximate) stochastic realizations. On the application side,...

  13. Application of Chaos Theory to Psychological Models

    Science.gov (United States)

    Blackerby, Rae Fortunato

    This dissertation shows that an alternative theoretical approach from physics--chaos theory--offers a viable basis for improved understanding of human beings and their behavior. Chaos theory provides achievable frameworks for potential identification, assessment, and adjustment of human behavior patterns. Most current psychological models fail to address the metaphysical conditions inherent in the human system, thus bringing deep errors to psychological practice and empirical research. Freudian, Jungian and behavioristic perspectives are inadequate psychological models because they assume, either implicitly or explicitly, that the human psychological system is a closed, linear system. On the other hand, Adlerian models that require open systems are likely to be empirically tenable. Logically, models will hold only if the model's assumptions hold. The innovative application of chaotic dynamics to psychological behavior is a promising theoretical development because the application asserts that human systems are open, nonlinear and self-organizing. Chaotic dynamics use nonlinear mathematical relationships among factors that influence human systems. This dissertation explores these mathematical relationships in the context of a sample model of moral behavior using simulated data. Mathematical equations with nonlinear feedback loops describe chaotic systems. Feedback loops govern the equations' value in subsequent calculation iterations. For example, changes in moral behavior are affected by an individual's own self-centeredness, family and community influences, and previous moral behavior choices that feed back to influence future choices. When applying these factors to the chaos equations, the model behaves like other chaotic systems. For example, changes in moral behavior fluctuate in regular patterns, as determined by the values of the individual, family and community factors. In some cases, these fluctuations converge to one value; in other cases, they diverge in

  14. Genetic demographic networks: Mathematical model and applications.

    Kimmel, Marek; Wojdyła, Tomasz

    2016-10-01

    Recent improvement in the quality of genetic data obtained from extinct human populations and their ancestors encourages searching for answers to basic questions regarding human population history. The most common and successful are model-based approaches, in which genetic data are compared to the data obtained from the assumed demography model. Using such approach, it is possible to either validate or adjust assumed demography. Model fit to data can be obtained based on reverse-time coalescent simulations or forward-time simulations. In this paper we introduce a computational method based on mathematical equation that allows obtaining joint distributions of pairs of individuals under a specified demography model, each of them characterized by a genetic variant at a chosen locus. The two individuals are randomly sampled from either the same or two different populations. The model assumes three types of demographic events (split, merge and migration). Populations evolve according to the time-continuous Moran model with drift and Markov-process mutation. This latter process is described by the Lyapunov-type equation introduced by O'Brien and generalized in our previous works. Application of this equation constitutes an original contribution. In the result section of the paper we present sample applications of our model to both simulated and literature-based demographies. Among other we include a study of the Slavs-Balts-Finns genetic relationship, in which we model split and migrations between the Balts and Slavs. We also include another example that involves the migration rates between farmers and hunters-gatherers, based on modern and ancient DNA samples. This latter process was previously studied using coalescent simulations. Our results are in general agreement with the previous method, which provides validation of our approach. Although our model is not an alternative to simulation methods in the practical sense, it provides an algorithm to compute pairwise

  15. Effect of therapeutic interchange on medication reconciliation during hospitalization and upon discharge in a geriatric population.

    Full Text Available Therapeutic interchange of a same class medication for an outpatient medication is a widespread practice during hospitalization in response to limited hospital formularies. However, therapeutic interchange may increase risk of medication errors. The objective was to characterize the prevalence and safety of therapeutic interchange.Secondary analysis of a transitions of care study. We included patients over age 64 admitted to a tertiary care hospital between 2009-2010 with heart failure, pneumonia, or acute coronary syndrome who were taking a medication in any of six commonly-interchanged classes on admission: proton pump inhibitors (PPIs, histamine H2-receptor antagonists (H2 blockers, hydroxymethylglutaryl CoA reductase inhibitors (statins, angiotensin-converting enzyme (ACE inhibitors, angiotensin receptor blockers (ARBs, and inhaled corticosteroids (ICS. There was limited electronic medication reconciliation support available. Main measures were presence and accuracy of therapeutic interchange during hospitalization, and rate of medication reconciliation errors on discharge. We examined charts of 303 patients taking 555 medications at time of admission in the six medication classes of interest. A total of 244 (44.0% of medications were therapeutically interchanged to an approved formulary drug at admission, affecting 64% of the study patients. Among the therapeutically interchanged drugs, we identified 78 (32.0% suspected medication conversion errors. The discharge medication reconciliation error rate was 11.5% among the 244 therapeutically interchanged medications, compared with 4.2% among the 311 unchanged medications (relative risk [RR] 2.75, 95% confidence interval [CI] 1.45-5.19.Therapeutic interchange was prevalent among hospitalized patients in this study and elevates the risk for potential medication errors during and after hospitalization.

    Arteries are under significant mechanical loads from blood pressure, flow, tissue tethering, and body movement. It is critical that arteries remain patent and stable under these loads. This review summarizes the common forms of buckling that occur in blood vessels including cross-sectional collapse, longitudinal twist buckling, and bent buckling. The phenomena, model analyses, experimental measurements, effects on blood flow, and clinical relevance are discussed. It is concluded that mechanical buckling is an important issue for vasculature, in addition to wall stiffness and strength, and requires further studies to address the challenges. Studies of vessel buckling not only enrich vascular biomechanics but also have important clinical applications. PMID:23192265

    2014-05-15

    A quality-improvement program at University of New Mexico Hospital (UNMH) encompassing admission, discharge, and postdischarge medication reconciliation activities is described, with a report on initial assessments of the program's impact on rates of medication-related problems (MRPs). Pharmacists conducted a five-month evaluation of the UNMH Care Transitions Service (CTS), which serves inpatients admitted to the hospital's family medicine service, providing medication reconciliation and targeted MRP interventions. Selected patients who received CTS services from November 2012 through March 2013 (n = 191) were included in the analysis. The study endpoints were the rates and types of MRPs identified, the most commonly implicated medication classes, and predictors of MRPs. Postdischarge MRP rates during a two-month trial of CTS services at a UNMH outpatient clinic were also evaluated. During the five-month evaluation of inpatient CTS services, a total of 1140 MRPs were identified (an average of 6 per patient), about 70% of which were resolved independently of provider review using pharmacy-driven protocols. During the two-month pilot test of CTS outpatient services (n = 16), a total of 28 MRPs were identified; in over 80% of cases, there was a decline in the number of MRPs from the admission to the postdischarge medication reconciliation. MRPs were identified through the continuum of care. The majority of MRPs identified in both the inpatient and outpatient settings involved patient variables and patient nonadherence. Seventy percent of inpatient MRPs were resolved independently by the CTS team under pharmacy-driven protocols.

    To explore inpatient reconciliation of dietary supplement (DS) use and determine characteristics associated with DS documentation. We analyzed DS use among 558 inpatients recruited from the Re-Engineered Discharge clinical trial to identify: (1) if patients self-reported DS and (2) if DS use was documented at admission. We examined socio-demographics for association with documentation using chi squares and t-tests. Logistic regression was performed to assess adjusted associations with DS documentation. Sixty percent reported DS use (n=333). Among users, 36% had admission DS documentation, 20% were asked about use at admission, 18% reported disclosing use to a provider, and 48% reported they would continue to use DS. Overall, 6% of participants were asked, disclosed, and had documentation of DS. Logistic regression revealed increased age associated with lower odds of DS documentation. Identifying as Hispanic or African American reduces DS documentation odds compared to those identifying as white. There is lack of consistent DS medical reconciliation in the inpatient setting. While more than half of patients used DS prior to hospitalization, most were not asked about use on admission. This study adds to literature on medical reconciliation which requires that providers inquire and document patient DS use. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available In 2008, the Truth and Reconciliation Commission of Canada (TRC was initiated to address the historical and contemporary injustices and impacts of Indian Residential Schools. Of the many goals of the TRC, I focus on reconciliation and how the TRC aims to promote this through public education and engagement. To explore this, I consider two questions:1 who does the TRC include in the process of reconciliation? And 2 how might I, as someone who is not Indigenous (specifically, as someone who is “white”, be engaged by the TRC?Ethical queries arise which speak to broader concerns about the TRC’s capability to fulfill its public education goals. I raise several concerns about whether the TRC’s plan to convoke the col- lective will result in over-simplifying the process by relying on blunt, poorly defined identity cate- gories that erase the heterogeneity of those residing in Canada, as well as the complexity of the conflict among us. I attempt to situate myself in-between proclamations of “success” or “failure” of the TRC, to better understand what can be learned from contested truths and experiences of uncertainty.

    Full Text Available Ignacio Ellacuría, a Jesuit philosopher and theologian, arrived at El Salvador, CentralAmerica, in 1967, during a period of enormous political and social turmoil that extended through the70’s and 80’s. Ellacuría, who acted as president of UCA from 1979 until his assassination in 1989, decided to orient the University’s and his own intellectual pursuit towards obtaining a deeper understanding of the about mentioned historical process. This article analyzes his contributions regarding the possibility of undertaking a peace process and a negotiation amidst an armed conflict. Ellacuría’s contributions, beyond the political analysis they entail, constitute a magnificent corpus of political philosophy regarding the issue of reconciliation. We analyze his discourse through seven key concepts with which the process that leads from «structural violence» to «true peace» is dynamically developed, i.e.: conflict, violence, cause, dialogue, pacification, peace and reconciliation.

  7. A conceptual holding model for veterinary applications

    2014-05-01

    Full Text Available Spatial references are required when geographical information systems (GIS are used for the collection, storage and management of data. In the veterinary domain, the spatial component of a holding (of animals is usually defined by coordinates, and no other relevant information needs to be interpreted or used for manipulation of the data in the GIS environment provided. Users trying to integrate or reuse spatial data organised in such a way, frequently face the problem of data incompatibility and inconsistency. The root of the problem lies in differences with respect to syntax as well as variations in the semantic, spatial and temporal representations of the geographic features. To overcome these problems and to facilitate the inter-operability of different GIS, spatial data must be defined according to a “schema” that includes the definition, acquisition, analysis, access, presentation and transfer of such data between different users and systems. We propose an application “schema” of holdings for GIS applications in the veterinary domain according to the European directive framework (directive 2007/2/EC - INSPIRE. The conceptual model put forward has been developed at two specific levels to produce the essential and the abstract model, respectively. The former establishes the conceptual linkage of the system design to the real world, while the latter describes how the system or software works. The result is an application “schema” that formalises and unifies the information-theoretic foundations of how to spatially represent a holding in order to ensure straightforward information-sharing within the veterinary community.

    Medication errors are one of the leading causes of patient harms. Medication reconciliation is a fundamental process that to be effective, it should be embraced during each single care transition. Our objectives were to investigate current medication reconciliation practices in the 2 Fondazione Toscana Gabriele Monasterio hospitals and comprehensively assess the quality of medication reconciliation practices between inpatient and outpatient care by analyzing the medication patterns 6 months before admission, during hospitalization, and 9 months after discharge for a selected group of patients with cardiovascular diseases. A retrospective observational study was conducted in the Cardiothoracic Department of the Fondazione Toscana Gabriele Monasterio hospitals. Medication history was reviewed for all the patients admitted from and discharged to the community, from January to March 2013. Patients were excluded if they had less than 4 drugs or less than 2 drugs for cardiovascular system in their prescription list at admission or if they died during follow-up. We selected 714 patients, and we obtained the clinical charts and all drug prescriptions collected during patients' hospitalization by the electronic clinical recording system. We also analyzed the list of prescriptions of this sample of patients, from 6 months before admission to 9 months after discharge, extracted from the regional prescription registry. In the resulting sample, prescriptions were analyzed to assess unintentional discrepancies. The study included 298 patients (mean age, 71.2 years), according to the inclusion and exclusion criteria. Among 14,573 prescriptions analyzed, we found 4363 discrepancies (14.6 discrepancies per patient). Among these discrepancies, 1310 were classified as unintentional (4.4 discrepancies per patient). Among unintentional discrepancies, only 63 (4.8%) took place during hospitalization. Although at the hospital-home interface, 33.1% of unintentional discrepancies were

    AIMS: Movement into or out of hospital is a vulnerable period for medication safety. Reconciling the medication a patient is using before admission with the medication prescribed on discharge, and documenting any changes (medication reconciliation) is recommended to improve safety. The aims of the study were to investigate the factors contributing to medication reconciliation on discharge, and identify the prevalence of non-reconciliation. METHODS: The study was a cross-sectional, observational survey using consecutive discharges from purposively selected services in two acute public hospitals in Ireland. Medication reconciliation, potential for harm and unplanned re-admission were investigated. RESULTS: Medication non-reconciliation was identified in 50% of 1245 inpatient episodes, involving 16% of 9569 medications. The majority of non-reconciled episodes had potential to result in moderate (63%) or severe (2%) harm. Handwritten rather than computerized discharges (adjusted odds ratio (adjusted OR) 1.60, 95% CI 1.11, 2.99), increasing number of medications (adjusted OR 1.26, 95% CI 1.21, 1.31) or chronic illness (adjusted OR 2.08, 95% CI 1.33, 3.24) were associated with non-reconciliation. Omission of endocrine, central nervous system and nutrition and blood drugs was more likely on discharge, whilst omission on admission and throughout inpatient care, without documentation, was more likely for obstetric, gynaecology and urinary tract (OGU) or respiratory drugs. Documentation in the discharge communication that medication was intentionally stopped during inpatient care was less likely for cardiovascular, musculoskeletal and OGU drugs. Errors involving the dose were most likely for respiratory drugs. CONCLUSIONS: The findings inform strategies to facilitate medication reconciliation on discharge from acute hospital care.

    Full Text Available Recent researches have shown that, everywhere in various sciences the systems are following stacked-based stored change behavior when subjected to events or varying environments “on and above” their normal situations. This paper presents a generalized data stack programming (GDSP model which is developed to describe the system changes under varying environment. These changes which are captured with different ways such as sensor reading are stored in matrices. Extraction algorithm and identification technique are proposed to extract the different layers between images and identify the stack class the object follows; respectively. The general multi-stacking network is presented including the interaction between various stack-based layering of some applications. The experiments prove that the concept of stack matrix gives average accuracy of 99.45%.

    2013-12-01

    Python is a general-purpose, high-level programming language whose design philosophy emphasizes code readability. Add-on packages supporting fast array computation (numpy), plotting (matplotlib), scientific /mathematical Functions (scipy), have resulted in a powerful ecosystem for scientists interested in exploratory data analysis, high-performance computing and data visualization. Three examples are provided to demonstrate the applicability of the Python environment in hydrogeological applications. Python programs were used to model an aquifer test and estimate aquifer parameters at a Superfund site. The aquifer test conducted at a Groundwater Circulation Well was modeled with the Python/FORTRAN-based TTIM Analytic Element Code. The aquifer parameters were estimated with PEST such that a good match was produced between the simulated and observed drawdowns. Python scripts were written to interface with PEST and visualize the results. A convolution-based approach was used to estimate source concentration histories based on observed concentrations at receptor locations. Unit Response Functions (URFs) that relate the receptor concentrations to a unit release at the source were derived with the ATRANS code. The impact of any releases at the source could then be estimated by convolving the source release history with the URFs. Python scripts were written to compute and visualize receptor concentrations for user-specified source histories. The framework provided a simple and elegant way to test various hypotheses about the site. A Python/FORTRAN-based program TYPECURVEGRID-Py was developed to compute and visualize groundwater elevations and drawdown through time in response to a regional uniform hydraulic gradient and the influence of pumping wells using either the Theis solution for a fully-confined aquifer or the Hantush-Jacob solution for a leaky confined aquifer. The program supports an arbitrary number of wells that can operate according to arbitrary schedules. The

    Cruickshank, David Raymond

    1998-12-01

    The adaptive filtering algorithm known as Genetic Model Compensation (GMC) was originally presented in the author's Master's Thesis. The current work extends this earlier work. GMC uses a genetic algorithm to optimize filter process noise parameters in parallel with the estimation of the state and based only on the observational information available to the filter. The original stochastic state model underlying GMC was inherited from the antecedent, non-adaptive Dynamic Model Compensation (DMC) algorithm. The current work develops the stochastic state model from a linear system viewpoint, avoiding the simplifications and approximations of the earlier development, and establishes Riemann sums as unbiased estimators of the stochastic integrals which describe the evolution of the random state components. These are significant developments which provide GMC with a solid theoretical foundation. Orbit determination is the area of application in this work, and two types of problems are studied: real-time autonomous filtering using absolute GPS measurements and precise post-processed filtering using differential GPS measurements. The first type is studied in a satellite navigation simulation in which pseudorange and pseudorange rate measurements are processed by an Extended Kalman Filter which incorporates both DMC and GMC. Both estimators are initialized by a geometric point solution algorithm. Using measurements corrupted by simulated Selective Availability errors, GMC reduces mean RSS position error by 6.4 percent, reduces mean clock bias error by 46 percent, and displays a marked improvement in covariance consistency relative to DMC. To study the second type of problem, GMC is integrated with NASA Jet Propulsion Laboratory's Gipsy/Oasis-II (GOA-II) precision orbit determination program creating an adaptive version of GOA-II's Reduced Dynamic Tracking (RDT) process noise formulation. When run as a sequential estimator with GPS measurements from the TOPEX satellite and

    The Big Bend Regional Aerosol and Visibility Observational (BRAVO) study was an intensive monitoring study from July through October 1999 followed by extensive assessments to determine the causes and sources of haze in Big Bend National Park, located in Southwestern Texas. Particulate sulfate compounds are the largest contributor of haze at Big Bend, and chemical transport models (CTMs) and receptor models were used to apportion the sulfate concentrations at Big Bend to North American source regions and the Carbón power plants, located 225 km southeast of Big Bend in Mexico. Initial source attribution methods had contributions that varied by a factor of > or =2. The evaluation and comparison of methods identified opposing biases between the CTMs and receptor models, indicating that the ensemble of results bounds the true source attribution results. The reconciliation of these differences led to the development of a hybrid receptor model merging the CTM results and air quality data, which allowed a nearly daily source apportionment of the sulfate at Big Bend during the BRAVO study. The best estimates from the reconciliation process resulted in sulfur dioxide (SO2) emissions from U.S. and Mexican sources contributing approximately 55% and 38%, respectively, of sulfate at Big Bend. The distribution among U.S. source regions was Texas, 16%; the Eastern United States, 30%; and the Western United States, 9%. The Carbón facilities contributed 19%, making them the largest single contributing facility. Sources in Mexico contributed to the sulfate at Big Bend on most days, whereas contributions from Texas and Eastern U.S. sources were episodic, with their largest contributions during Big Bend sulfate episodes. On the 20% of the days with the highest sulfate concentrations, U.S. and Mexican sources contributed approximately 71% and 26% of the sulfate, respectively. However, on the 20% of days with the lowest sulfate concentrations, Mexico contributed 48% compared with 40

    Full Text Available The TRC re-enactment consultation18 afforded the opportunity to reflect on the leadership of religious leaders during the apartheid era, and in the years that followed. This chapter is particularly interested in the prophetic leadership provided by religious leaders during apartheid, and 20 years following the transition by engaging with some normative thoughts on prophetic dialogue. The findings on the leadership provided during the post-TRC are reflected upon in terms of reconciliation through the hermeneutical lens of the Belgian scholar Valarie Rosoux. Hereby, this chapter seeked to contribute to reconciliation and national unity in the current South African context with some strategic conclusions to ensure that the process of reconciliation becomes a priority for all faith communities across the nation.

    2017-05-01

    Full Text Available This article contributes to the assessment of the management of migrants at the end of the 16th century as part of the challenge, by both central and municipal authorities, for ending the civil war in the Spanish Low Countries. In particular, it questions to what extent experiences of exiles, returnees and migrants presented a challenge for families, economic regulation and public order in the French-speaking reconciled provinces (Hainaut, Artois and the Walloon Flanders, in the new framework of the pacification and religious normalization. It focuses on how did the towns, when confronted with various forms of mobility, attempt to apply the practice of reconciliation. On the one hand, the general policy of reconciliation tried to build a post bellum society under the Roman Catholic faith and the King’s sovereignty, not only by excluding those who refused to recant in order to conform to the rules of the pacification, but also by forgiving and reincorporating the migrants who crossed confessional boundaries. Then, it considers how, at their level, the municipal authorities had to take various patterns of migration into account, in particular those that connected most of the towns of the Union of Arras to the Protestant Refuge in England and the Dutch Republic, reducing the importance of the migrants’ religious status in their selection criteria. Finally, theses practices opened a space for discussion and a shy civic toleration between the Catholic aldermen, the ex-Calvinists who had chosen official reconciliation, and the textile workers migrants while still being accommodated and welcomed into the exile Protestant Churches, relegating the debate about personal confessional practices and religion from public space to the family sphere.

    Background Medication reconciliation has been mandated by the Irish government at transfer of care. Research is needed to determine the contribution of clinical pharmacists to the process. Objective To describe the contribution of emergency department based clinical pharmacists to admission medication reconciliation in Ireland. Main Outcome Measure Frequency of clinical pharmacist\\'s activities. Setting Two public university teaching hospitals. Methodology Adults admitted via the accident and emergency department, from a non-acute setting, reporting the use of at least three regular prescription medications, were eligible for inclusion. Medication reconciliation was provided by clinical pharmacists to randomly-selected patients within 24-hours of admission. This process includes collecting a gold-standard pre-admission medication list, checking this against the admission prescription and communicating any changes. A discrepancy was defined as any difference between the gold-standard pre-admission medication list and the admission prescription. Discrepancies were communicated to the clinician in the patient\\'s healthcare record. Potentially harmful discrepancies were also communicated verbally. Pharmacist activities and unintentional discrepancies, both resolved and unresolved at 48-hours were measured. Unresolved discrepancies were confirmed verbally by the team as intentional or unintentional. A reliable and validated tool was used to assess clinical significance by medical consultants, clinical pharmacists, community pharmacists and general practitioners. Results In total, 134 patients, involving 1,556 medications, were included in the survey. Over 97 % of patients (involving 59 % of medications) experienced a medication change on admission. Over 90 % of patients (involving 29 % of medications) warranted clinical pharmacy input to determine whether such changes were intentional or unintentional. There were 447 interventions by the clinical pharmacist regarding

    2017-10-01

    Despite the investment in exploring patient-centred alternatives to medical malpractice in New Zealand (NZ), the UK and the USA, patients' experiences with these processes are not well understood. We sought to explore factors that facilitate and impede reconciliation following patient safety incidents and identify recommendations for strengthening institution-led alternatives to malpractice litigation. We conducted semistructured interviews with 62 patients injured by healthcare in NZ, administrators of 12 public hospitals, 5 lawyers specialising in Accident Compensation Corporation (ACC) claims and 3 ACC staff. NZ was chosen as the research site because it has replaced medical malpractice litigation with a no-fault scheme. Thematic analysis was used to identify key themes from interview transcripts. Interview responses converged on five elements of the reconciliation process that were important: (1) ask, rather than assume, what patients and families need from the process and recognise that, for many patients, being heard is important and should occur early in the reconciliation process; (2) support timely, sincere, culturally appropriate and meaningful apologies, avoiding forced or tokenistic quasi-apologies; (3) choose words that promote reconciliation; (4) include the people who patients want involved in the reconciliation discussion, including practitioners involved in the harm event; and (5) engage the support of lawyers and patient relations staff as appropriate. Policymakers and healthcare institutions are keenly interested in non-litigation approaches to resolving malpractice incidents. Interviewing participants involved in patient safety incident reconciliation processes suggests that healthcare institutions should not view apology as a substitute for other remedial actions; use flexible guidelines that distil best-practice principles, ensuring that steps are not missed, while not prescribing a 'one size fits all' communication approach.

    New ESA missions dedicated to the observation of the Earth from space, like the gravity-gradiometry mission GOCE and the radar altimetry mission CRYOSAT 2, foster research, among other subjects, also on inverse gravimetric problems and on the description of the nature and the geographical location of gravimetric signals. In this framework the GEMMA project (GOCE Exploitation for Moho Modeling and Applications), funded by the European Space Agency and Politecnico di Milano, aims at estimating the boundary between Earth's crust and mantle (the so called Mohorovičić discontinuity or Moho) from GOCE data in key regions of the world. In the project a solution based on a simple two layer model in spherical approximation is proposed. This inversion problem based on the linearization of the Newton's gravitational law around an approximate mean Moho surface will be solved by exploiting Wiener-Kolmogorov theory in the frequency domain where the depth of the Moho discontinuity will be treated as a random signal with a zero mean and its own covariance function. The algorithm can be applied in a numerically efficient way by using the Fast Fourier Transform. As for the gravity observations, we will consider grids of the anomalous gravitational potential and its second radial derivative at satellite altitude. In particular this will require first of all to elaborate GOCE data to obtain a local grid of the gravitational potential field and its second radial derivative and after that to separate the gravimetric signal due to the considered discontinuity from the gravitational effects of other geological structures present into the observations. The first problem can be solved by applying the so called space- wise approach to GOCE observations, while the second one can be achieved by considering a priori models and geophysical information by means of an appropriate Bayesan technique. Moreover other data such as ground gravity anomalies or seismic profiles can be combined, in an

    It has proven to be a challenge for health care organizations to achieve the Triple Aim. In the business literature, business model frameworks have been used to understand how organizations are aligned to achieve their goals. We conducted a systematic literature review with an explanatory synthesis approach to understand how business model frameworks have been applied in health care. We found a large increase in applications of business model frameworks during the last decade. E-health was the most common context of application. We identified six applications of business model frameworks: business model description, financial assessment, classification based on pre-defined typologies, business model analysis, development, and evaluation. Our synthesis suggests that the choice of business model framework and constituent elements should be informed by the intent and context of application. We see a need for harmonization in the choice of elements in order to increase generalizability, simplify application, and help organizations realize the Triple Aim.

  8. Peace-building and reconciliation dividends of integrated health services delivery in post-conflict Burundi: qualitative assessments of providers and community members.

    Christensen, Cathryn; Edward, Anbrasi

    2015-01-01

    While demonstrating causality remains challenging, several 'health-peace' mechanisms have been proposed to describe how health systems contribute to peace-building and stability in post-conflict settings. A qualitative study was undertaken in southern Burundi to identify drivers of social tension and reconciliation in the catchment area of Village Health Works, a health services organisation. Key informant interviews and focus group discussions were conducted in early 2014 with a total of one hundred and twenty community members and staff representing a range of conflict and recovery experience. Themes emerging from these interviews indicated mechanisms at the individual, household, community, and regional levels through which health provision mitigates tensions and promotes social cohesion. This peace dividend was amplified by the clinic's integrated model, which facilitates further community interaction through economic, agricultural and education programmes. Land pressure and the marginalisation of repatriated refugees were cited as drivers of local tension.

    2012-01-01

    In conventional causality testing based on asymptotic distribution theory, there is a high risk of wrongly rejecting the true null of no causality especially when the sample size is as small as typically seen in the literature. In this study, we offer a formal diagnosis of the existing contradictory results on the causal relationship between energy consumption and real GDP. We also employ a time series oriented advanced data generation process to perform simulation based inference for the People's Republic of China. Our study covers the 1971–2007 period and considers five different aggregated and disaggregated energy consumption measures as well as three different lag orders in both a bivariate as well as a multivariate frameworks. Our maximum entropy bootstrap based analysis, which avoids pretest biases and is also robust to Type I errors, supports the neutrality hypothesis in 53 out of the total of 60 model estimations. The strong results show that coarse aggregate data has a limited potential to observe the complex causal linkages between energy consumption and economic growth. Future policy oriented research on this nexus requires more focused analyses based on sectoral and provincial data. - Highlights: ► Some of the contradictory findings on the energy–growth nexus are due to asymptotic testing under small samples. ► The bootstrap method can provide huge improvements upon the approximations of asymptotic theory. ► 53 out of a total of 60 models that we consider consistently support the neutrality hypothesis for China. ► Future policy oriented research on this nexus should aim toward detailed analyses using sectoral and provincial data.

  11. Toward a theory of self-reconciliation following mistakes in nursing practice.

    2007-01-01

    To explore nurses' responses to making mistakes in hospital-based practice in the US. A grounded theory approach was used to explore the process that occurs after nurses perceive that they have made mistakes in practice. Theoretical sampling was used and data were collected until saturation occurred. Ten participants, who were registered nurses, described 17 personal mistakes. The mistakes they described occurred in hospitals. All participants were practicing nursing either in hospitals or in other work settings. A process of "Self-Reconciliation After Making Mistakes in Hospital Practice" was identified, with four distinct categories: reality hitting, weighing in, acting, and reconciling. The core category was reconciliation of the self, personally and professionally. This research was a first step toward the development of a theory of mistake making in nursing practice. This response to making mistakes is consistent with previous research and is related to cognitive dissonance theory. The responses to mistakes varied from less healthy responses of blaming and silence to healthier responses that included disclosure, apologizing, and making amends. Further research to develop the theory and to determine helpful interventions is suggested.

  12. Building a peaceful society: origins, prevention, and reconciliation after genocide and other group violence.

    Staub, Ervin

    2013-10-01

    The 20th century was a century of genocide and other great violence between groups within societies. Already at the beginning of the 21st century, there have been mass killings, civil wars, violent conflict, and terrorism. This article summarizes influences that tend to lead to intense group violence. It then considers prevention, stressing early prevention--and reconciliation as an aspect of prevention--and focusing on central principles and practices. The principles include developing positive orientations to previously devalued groups; healing from past victimization and promoting altruism born of suffering; moderating respect for authority; creating constructive ideologies; promoting understanding of the origins of violence, its impact, and avenues to prevention; promoting truth, justice, and a shared history; and raising inclusively caring, morally courageous children. Practices related to all of these are also discussed. The article stresses the role of progressive change, that is, of psychological, behavioral, and social evolution, in both extreme violence and positive relations between groups; the role of passive bystanders in the unfolding of violence; and the role of active bystandership in the prevention of violence, in the promotion of reconciliation, and in the development of harmonious societies. It emphasizes psychological processes but notes the importance of creating societal institutions. The author cites findings from both laboratory research and case studies, reviews interventions and their evaluation in Rwanda, and points to the need for further research.

    Full Text Available In 2006, the Government of Canada announced the approval of a final Residential Schools Settlement Agreement with the collaboration of the four churches responsible (United, Anglican, Presbyterian, Catholic, the federal government and residential school survivors. Schedule "N" of the Agreement lists the mandate of the TRC; therein, the TRC states one of its goals as: (d to promote awareness and public education of Canadians about the system and its impacts. Can education - as the TRC hopes to engender - truly be transformative, renewing relationships and promoting healing in the process of forging these new relationships? The literature reviewed and the conferences attended highlighted that generating empathy maybe a necessary ingredient for the instigation of social change, but is insufficient. Transformation through education, or reconciliation through truth-telling, testimonial reading and responsible listening would mean claiming a genuine, supportive responsibility for the colonial past. Educational policy and media initiatives are fundamental to creating awareness, developing public interest and support of the TRC's recommendations. However, authors also stress the importance of critical pedagogy in the whole process of truth andreconciliation, and that real reconciliation would require confronting the racism that initiated these institutions and allowed for a decontextualization of their impacts.

  14. Reconciliation and Revenge in Post-Apartheid South Africa. Rethinking Legal Pluralism and Human Rights.

    Human rights are a central element in the new governmental project in the new South Africa, and this article traces some of the specific forms of connection and disconnection between notions of justice found in townships of the Vaal and rights discourses as articulated by the Truth and Reconciliation Commission. The introduction of human rights in post-apartheid South Africa has had varied social effects. Religious values and human rights discourse have converged on the notion of reconciliation on the basis of shared value orientations and institutional structures. There are clear divergences, however, between human rights ideas and the notions of justice expressed in local lekgotla, or township courts, which emphasize punishment and retribution. The article concludes that the plurality of legal orders in South Africa results not from systemic relations between law and society but from multiple forms of social action seeking to alter the direction of social change in the area of justice within the context of the nation-building project of the post-apartheid state.

    Lagarde, J; Sarazin, M

    2017-10-01

    Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation. Among psychiatric symptoms reported in this disease, psychotic symptoms (hallucinations, delusions, especially of persecution), which have long been underestimated in bvFTD and are not part of the current diagnostic criteria, are present in about 20% of cases and may be inaugural. They are particularly common in the genetic forms related to a mutation in the C9orf72 gene (up to 50%), and to a lesser extent in the GRN gene (up to 25%). C9orf72 gene mutation is often associated with a family history of dementia or motor neuron disease but also of psychiatric disorders. It has also been described in sporadic presentation forms. Sometimes, the moderate degree of brain atrophy on MRI described in patients carrying this mutation may complicate the differential diagnosis with late-onset psychiatric diseases. In the present article, we underline the importance of considering that psychiatric - especially psychotic - symptoms are not rare in bvFTD, which should lead to a revision of the diagnostic criteria of this disease by taking greater account of this fact. We also propose a diagnostic chart, based on concerted evaluation by neurologists and psychiatrists for cases of atypical psychiatric symptoms (late-onset or pharmacoresistant troubles) leading to consider the possibility of a neurological disorder, in order to shed a new light on these difficult clinical situations. In the field of research, bvFTD may constitute a model to explore the neural basis of certain

  19. Surface Flux Modeling for Air Quality Applications

    Directory of Open Access Journals (Sweden)

    Limei Ran

    2011-08-01

    Full Text Available For many gasses and aerosols, dry deposition is an important sink of atmospheric mass. Dry deposition fluxes are also important sources of pollutants to terrestrial and aquatic ecosystems. The surface fluxes of some gases, such as ammonia, mercury, and certain volatile organic compounds, can be upward into the air as well as downward to the surface and therefore should be modeled as bi-directional fluxes. Model parameterizations of dry deposition in air quality models have been represented by simple electrical resistance analogs for almost 30 years. Uncertainties in surface flux modeling in global to mesoscale models are being slowly reduced as more field measurements provide constraints on parameterizations. However, at the same time, more chemical species are being added to surface flux models as air quality models are expanded to include more complex chemistry and are being applied to a wider array of environmental issues. Since surface flux measurements of many of these chemicals are still lacking, resistances are usually parameterized using simple scaling by water or lipid solubility and reactivity. Advances in recent years have included bi-directional flux algorithms that require a shift from pre-computation of deposition velocities to fully integrated surface flux calculations within air quality models. Improved modeling of the stomatal component of chemical surface fluxes has resulted from improved evapotranspiration modeling in land surface models and closer integration between meteorology and air quality models. Satellite-derived land use characterization and vegetation products and indices are improving model representation of spatial and temporal variations in surface flux processes. This review describes the current state of chemical dry deposition modeling, recent progress in bi-directional flux modeling, synergistic model development research with field measurements, and coupling with meteorological land surface models.

  20. On the significance of saying “sorry” – politics of memory and Aboriginal Reconciliation in Australia

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available 2007 marked the 40th anniversary of the 1967 Referendum. Back on May 27th 1967, more than 90% of Australian eligible voters said “yes’ to two changes of the Australian Constitution considered discriminatory to Aboriginal people. This event is often considered as the first stage of Reconciliation in Australia. 2007 also marked the 10th Anniversary of the release of the Bringing Them Home Report that highlighted the forced removal of Aboriginal children from their family as part of an assimilation policy. From 1997, the issue of an apology became a sine qua non condition to Reconciliation. It was an important element of the recommendations the Council for Aboriginal Reconciliation submitted to Parliament in 2000. But, Liberal Prime Minister John Howard, in office for more than ten years, refused to say the word “sorry” on the basis that Australians of today are not responsible for the actions of the past and that guilt is not hereditary. His focus was on what is called “practical reconciliation”. Some changes are now on the way as Labor leader, Kevin Rudd, who defeated him at the last federal election in November 24th 2007, has promised to make a formal apology to the stolen generation. Why is it important to say “sorry”? At a time of dramatic developments in Indigenous Affairs, this paper deals with the significance of an apology for Reconciliation in Australia.

    Full Text Available Objectives: To evaluate the impact of a pharmacy-technician centered medication reconciliation (PTMR program by identifying and quantifying medication discrepancies and outcomes of pharmacist medication reconciliation recommendations. Methods: A retrospective chart review was performed on two-hundred patients admitted to the internal medicine teaching services at Cooper University Hospital in Camden, NJ. Patients were selected using a stratified systematic sample approach and were included if they received a pharmacy technician medication history and a pharmacist medication reconciliation at any point during their hospital admission. Pharmacist identified medication discrepancies were analyzed using descriptive statistics, bivariate analyses. Potential risk factors were identified using multivariate analyses, such as logistic regression and CART. The priority level of significance was set at 0.05. Results: Three-hundred and sixty-five medication discrepancies were identified out of the 200 included patients. The four most common discrepancies were omission (64.7%, non-formulary omission (16.2%, dose discrepancy (10.1%, and frequency discrepancy (4.1%. Twenty-two percent of pharmacist recommendations were implemented by the prescriber within 72 hours. Conclusion: A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

  9. An Observational Study to Evaluate the Usability and Intent to Adopt an Artificial Intelligence–Powered Medication Reconciliation Tool

    Science.gov (United States)

    Yuan, Michael Juntao; Poonawala, Robina

    2016-01-01

    Background Medication reconciliation (the process of creating an accurate list of all medications a patient is taking) is a widely practiced procedure to reduce medication errors. It is mandated by the Joint Commission and reimbursed by Medicare. Yet, in practice, medication reconciliation is often not effective owing to knowledge gaps in the team. A promising approach to improve medication reconciliation is to incorporate artificial intelligence (AI) decision support tools into the process to engage patients and bridge the knowledge gap. Objective The aim of this study was to improve the accuracy and efficiency of medication reconciliation by engaging the patient, the nurse, and the physician as a team via an iPad tool. With assistance from the AI agent, the patient will review his or her own medication list from the electronic medical record (EMR) and annotate changes, before reviewing together with the physician and making decisions on the shared iPad screen. Methods In this study, we developed iPad-based software tools, with AI decision support, to engage patients to “self-service” medication reconciliation and then share the annotated reconciled list with the physician. To evaluate the software tool’s user interface and workflow, a small number of patients (10) in a primary care clinic were recruited, and they were observed through the whole process during a pilot study. The patients are surveyed for the tool’s usability afterward. Results All patients were able to complete the medication reconciliation process correctly. Every patient found at least one error or other issues with their EMR medication lists. All of them reported that the tool was easy to use, and 8 of 10 patients reported that they will use the tool in the future. However, few patients interacted with the learning modules in the tool. The physician and nurses reported the tool to be easy-to-use, easy to integrate into existing workflow, and potentially time-saving. Conclusions We have

    1993-01-01

    The application of an autoregressive (AR) model to estimating noise measurements has achieved many successes in reactor noise analysis in the last ten years. The physical processes that take place in the nuclear reactor, however, are described by an autoregressive moving average (ARMA) model rather than by an AR model. Consequently more correct results could be obtained by applying the ARMA model instead of the AR model to reactor noise analysis. In this paper the system of the generalised Yule-Walker equations is derived from the equation of an ARMA model, then a method for its solution is given. Numerical results show the applications of the method proposed. (author)

    2010-10-01

    In December 2007, the National Institute for Health and Clinical Excellence and the National Patient Safety Agency in the UK (NICE-NPSA) published guidance that recommends all adults admitted to hospital receive medication reconciliation, usually by pharmacy staff. A costing and report tool was provided indicating a resource requirement of 12.9 million pounds for England per year. Pediatric patients are excluded from this guidance. To determine the clinical significance of medication reconciliation in children on admission to hospital. A prospective observational study included pediatric patients admitted to a neurosurgical ward at Birmingham Children's Hospital, Birmingham, England, between September 2006 and March 2007. Medication reconciliation was conducted by a pharmacist after the admission of each of 100 consecutive eligible patients aged 4 months to 16 years. The clinical significance of prescribing disparities between pre-admission medications and initial admission medication orders was determined by an expert multidisciplinary panel and quantified using an analog scale. The main outcome measure was the clinical significance of unintentional variations between hospital admission medication orders and physician-prescribed pre-admission medication for repeat (continuing) medications. Initial admission medication orders for children differed from prescribed pre-admission medication in 39% of cases. Half of all resulting prescribing variations in this setting had the potential to cause moderate or severe discomfort or clinical deterioration. These results mirror findings for adults. The introduction of medication reconciliation in children on admission to hospital has the potential to reduce discomfort or clinical deterioration by reducing unintentional changes to repeat prescribed medication. Consequently, there is no justification for the omission of children from the NICE-NPSA guidance concerning medication reconciliation in hospitals, and costing tools

    An analytical model is presented that is able to describe the performance of OCT systems in both the single and multiple scattering regimes simultaneously. This model inherently includes the shower curtain effect, well-known for light propagation through the atmosphere. This effect has been omitted...... in previous theoretical models of OCT systems. It is demonstrated that the shower curtain effect is of utmost importance in the theoretical description of an OCT system. The analytical model, together with proper noise analysis of the OCT system, enables calculation of the SNR, where the optical properties...... geometry, i.e., reflection geometry, is developed. As in the new OCT model, multiple scattered photons has been taken into account together with multiple scattering effects. As an important result, a novel method of creating images based on measurements of the momentum width of the Wigner phase...

    2014-01-01

    Much work on fuzzy control, covering research, development and applications, has been developed in Europe since the 90's. Nevertheless, the existing books in the field are compilations of articles without interconnection or logical structure or they express the personal point of view of the author. This book compiles the developments of researchers with demonstrated experience in the field of fuzzy control following a logic structure and a unified the style. The first chapters of the book are dedicated to the introduction of the main fuzzy logic techniques, where the following chapters focus on concrete applications. This book is supported by the EUSFLAT and CEA-IFAC societies, which include a large number of researchers in the field of fuzzy logic and control. The central topic of the book, Fuzzy Control, is one of the main research and development lines covered by these associations.

  7. The Germans revisiting Gakovo: Encounters, cooperation and reconciliation of the former and present local populations

    2015-01-01

    Full Text Available This paper presents a case study about a reunion of the evicted members of the German national minority in Vojvodina, who after almost five decades came to visit their homeland, and the local population in Gakovo. The case study attests about lengthy and very complicated process in resolving post-conflict situations. The process’ launch is dependent on the willingness of the individuals involved to face not only one’s own pain caused by the enemy, but also on ability to comprehend, during an encounter with “the dark side of one’s past”, sufferings and humiliation experienced by the adversary. Awareness and acceptance of one’s own responsibility in the conflict are a prerequisite for forgiveness and reconciliation of the opposing parties. The outcome of this process is uncertain to the very end and conditioned upon the entire network of interlocking political, economic and cultural factors.

  8. Relies of reconciliation: the Confederate Museum and Civil War memory in the New South.

    Science.gov (United States)

    Hillyer, Reiko

    2011-11-01

    This article examines the Confederate Memorial Literary Society (CMLS), an organization of elite white women in Richmond, Virginia who founded the Confederate Museum in the 1890s. Faced with the plunder of Civil War relics and cultural homogenization on northern terms, the CMLS founded the Confederate Museum to document and defend the Confederate cause and to uphold the antebellum mores that the New South's business ethos threatened to erode. In the end, however, the museum's version of the Lost Cause served the New South. By focusing on military sacrifice, the Confederate Museum aided the process of sectional reconciliation. By depicting slavery as benevolent, the museum's exhibits reinforced the notion that Jim Crow was a just and effective means of managing postwar southern society. Lastly, by glorifying the common soldier and portraying the South as "solid," the museum promoted obedience to the mandates of industrial capitalism. Thus, the Confederate Museum both critiqued and eased the economic transformations of the New South.

    Full Text Available This article is dedicated to recounting the main initiative of Nelson Mandela’s government to manage the social resentment inherited from the segregationist regime. I conducted interviews with South African intellectuals committed to the theme of transitional justice and with key personalities who played a critical role in this process. The Truth and Reconciliation Commission is presented as the primary institutional mechanism envisioned for the delicate exercise of redefining social relations inherited from the apartheid regime in South Africa. Its founders declared grandiose political intentions to the detriment of localized more palpable objectives. Thus, there was a marked disparity between the ambitious mandate and the political discourse about the commission, and its actual achievements.

    2017-12-01

    Full Text Available This article draws on a well-known narration of the Gugulethu Seven incident from the Truth and Reconciliation Commission (TRC proceedings with specific reference to testimonies of the mothers of the Gugulethu Seven. The article focuses on Mrs Konile’s testimony as a case study: Testimony of a black woman whose son was murdered by the apartheid government’s security forces. During the TRC hearings, Mrs Konile ‘failed’ to effectively narrate her story, which resulted in her testimony being dismissed as being incoherent. This article examines the underlying attributes of Mrs Konile’s testimony and revisits why she was considered ‘incapable’ of articulating her experience in a convincing manner. The analysis aims to acknowledge, identify and give insights about this woman’s testimony from an African women theologian viewpoint (specifically with references to the Isixhosa religious cultural background.

  11. Informal and formal reconciliation strategies of older peoples’ working carers: the European carers@work project

    Directory of Open Access Journals (Sweden)

    Andreas Hoff

    2014-07-01

    Full Text Available Faced with a historically unprecedented process of demographic ageing, many European societies implemented pension reforms in recent years to extend working lives. Although aimed at rebalancing public pension systems, this approach has the unintended side effect that it also extends the number of years in which working carers have to juggle the conflicting demands of employment and caregiving. This not only impinges on working carers’ well-being and ability to continue providing care but also affects European enterprises’ capacity to generate growth which increasingly relies on ageing workforces. The focus of this paper will thus be a cross-national comparison of individual reconciliation strategies and workplace-related company policies aimed at enabling working carers to reconcile both conflicting roles in four different European welfare states: Germany, Italy, Poland, and the United Kingdom.

  1. A broadcast-based key agreement scheme using set reconciliation for wireless body area networks.

    Science.gov (United States)

    Ali, Aftab; Khan, Farrukh Aslam

    2014-05-01

    Information and communication technologies have thrived over the last few years. Healthcare systems have also benefited from this progression. A wireless body area network (WBAN) consists of small, low-power sensors used to monitor human physiological values remotely, which enables physicians to remotely monitor the health of patients. Communication security in WBANs is essential because it involves human physiological data. Key agreement and authentication are the primary issues in the security of WBANs. To agree upon a common key, the nodes exchange information with each other using wireless communication. This information exchange process must be secure enough or the information exchange should be minimized to a certain level so that if information leak occurs, it does not affect the overall system. Most of the existing solutions for this problem exchange too much information for the sake of key agreement; getting this information is sufficient for an attacker to reproduce the key. Set reconciliation is a technique used to reconcile two similar sets held by two different hosts with minimal communication complexity. This paper presents a broadcast-based key agreement scheme using set reconciliation for secure communication in WBANs. The proposed scheme allows the neighboring nodes to agree upon a common key with the personal server (PS), generated from the electrocardiogram (EKG) feature set of the host body. Minimal information is exchanged in a broadcast manner, and even if every node is missing a different subset, by reconciling these feature sets, the whole network will still agree upon a single common key. Because of the limited information exchange, if an attacker gets the information in any way, he/she will not be able to reproduce the key. The proposed scheme mitigates replay, selective forwarding, and denial of service attacks using a challenge-response authentication mechanism. The simulation results show that the proposed scheme has a great deal of

    Full Text Available In the modern legal system of the Republic of Kazakhstan development of the mechanism for reconciliation was worked out. The President of the Republic of Kazakhstan has repeatedly pointed out the need to implement progressive world experience of extrajudicial reconciliation. This is the idea of various forms of mediation introduction in the settlement of disputes enshrined in the Concept of Legal Policy of the Republic of Kazakhstan for the period from 2010 to 2020. At the same time there is the Law "On Mediation" of the year 2011 in the Republic of Kazakhstan, which has to create legal basis for the broad and civilized use of this procedure and to reduce the increasing burden on the courts. The analysis showed that the adoption of the Law "On Mediation" has not led to a decrease load on the courts; mediation is not widespread among the population and underdeveloped. It was also noted in the article, that in 2013, for example, the courts completed only 3% of civil cases by settlement. Authors conclude that for the serious crimes, firstly committed and not connected with the death or grievous bodily harm could be settled not only between minors, but also among other socially vulnerable people - pregnant women, mothers with dependent minor children, senior citizens. Authors note that the range of methods of conciliation is large enough. It develops, including all new mechanisms into the category of the means by which it is possible to resolve any conflict without recourse to the state Justice. Consequently, the expansion of pre-trial settlement of disputes, the introduction of a simplified form of consideration of claims would contribute to the further development of fast and affordable justice.

  3. A Component-based Programming Model for Composite, Distributed Applications

    Science.gov (United States)

    Eidson, Thomas M.; Bushnell, Dennis M. (Technical Monitor)

    2001-01-01

    The nature of scientific programming is evolving to larger, composite applications that are composed of smaller element applications. These composite applications are more frequently being targeted for distributed, heterogeneous networks of computers. They are most likely programmed by a group of developers. Software component technology and computational frameworks are being proposed and developed to meet the programming requirements of these new applications. Historically, programming systems have had a hard time being accepted by the scientific programming community. In this paper, a programming model is outlined that attempts to organize the software component concepts and fundamental programming entities into programming abstractions that will be better understood by the application developers. The programming model is designed to support computational frameworks that manage many of the tedious programming details, but also that allow sufficient programmer control to design an accurate, high-performance application.

    In the last few years, a number of NLP researchers have developed and participated in the task of Recognizing Textual Entailment (RTE). This task encapsulates Natural Language Understanding capabilities within a very simple interface: recognizing when the meaning of a text snippet is contained in the meaning of a second piece of text. This simple abstraction of an exceedingly complex problem has broad appeal partly because it can be conceived also as a component in other NLP applications, from Machine Translation to Semantic Search to Information Extraction.

  7. Model evaluation methodology applicable to environmental assessment models

    International Nuclear Information System (INIS)

    Shaeffer, D.L.

    1979-08-01

    A model evaluation methodology is presented to provide a systematic framework within which the adequacy of environmental assessment models might be examined. The necessity for such a tool is motivated by the widespread use of models for predicting the environmental consequences of various human activities and by the reliance on these model predictions for deciding whether a particular activity requires the deployment of costly control measures. Consequently, the uncertainty associated with prediction must be established for the use of such models. The methodology presented here consists of six major tasks: model examination, algorithm examination, data evaluation, sensitivity analyses, validation studies, and code comparison. This methodology is presented in the form of a flowchart to show the logical interrelatedness of the various tasks. Emphasis has been placed on identifying those parameters which are most important in determining the predictive outputs of a model. Importance has been attached to the process of collecting quality data. A method has been developed for analyzing multiplicative chain models when the input parameters are statistically independent and lognormally distributed. Latin hypercube sampling has been offered as a promising candidate for doing sensitivity analyses. Several different ways of viewing the validity of a model have been presented. Criteria are presented for selecting models for environmental assessment purposes

    Bonaccorso, Timary Annie

    2011-01-01

    This study models mantle convection on Venus using the 'cubed sphere' code OEDIPUS, which models one-sixth of the planet in spherical geometry. We are attempting to balance internal heating, bottom mantle viscosity, and temperature difference across Venus' mantle, in order to create a realistic model that matches with current planetary observations. We also have begun to run both lower and upper mantle simulations to determine whether layered (as opposed to whole-mantle) convection might produce more efficient heat transfer, as well as to model coronae formation in the upper mantle. Upper mantle simulations are completed using OEDIPUS' Cartesian counterpart, JOCASTA. This summer's central question has been how to define a mantle plume. Traditionally, we have defined a hot plume the region with temperature at or above 40% of the difference between the maximum and horizontally averaged temperature, and a cold plume as the region with 40% of the difference between the minimum and average temperature. For less viscous cases (1020 Pa?s), the plumes generated by that definition lacked vigor, displaying buoyancies 1/100th of those found in previous, higher viscosity simulations (1021 Pa?s). As the mantle plumes with large buoyancy flux are most likely to produce topographic uplift and volcanism, the low viscosity cases' plumes may not produce observable deformation. In an effort to eliminate the smallest plumes, we experimented with different lower bound parameters and temperature percentages.

    Adverse drug events are responsible for up to 7% of all admissions to acute care hospitals. At least 58% of these are preventable, resulting from incomplete drug information, prescribing or dispensing errors, and overuse or underuse of medications. Effective implementation of medication reconciliation is considered essential to reduce preventable adverse drug events occurring at transitions between community and hospital care. An electronically enabled discharge reconciliation process represents an innovative approach to this problem. Participants will be recruited in Quebec and are eligible for inclusion if they are using prescription medication at admission, covered by the Quebec drug insurance plan, admitted from the community, 18 years or older, admitted to a general or intensive care medical or surgical unit, and discharged alive. A sample size of 3,714 will be required to detect a 5% reduction in adverse drug events. The intervention will comprise electronic retrieval of the community drug list, combined with an electronic discharge reconciliation module and an electronic discharge communication module. The primary outcomes will be adverse drug events occurring 30 days post-discharge, identified by a combination of patient self-report and chart abstraction. All emergency room visits and hospital readmission during this period will be measured as secondary outcomes. A cluster randomization approach will be used to allocate 16 medical and 10 surgical units to electronic discharge reconciliation and communication versus usual care. An intention-to-treat approach will be used to analyse data. Logistic regression will be undertaken within a generalized estimating equation framework to account for clustering within units. The goal of this prospective trial is to determine if electronically enabled discharge reconciliation will reduce the risk of adverse drug events, emergency room visits and readmissions 30 days post-discharge compared with usual care. We expect

    A prognostic model is being used to provide regional forecasts for a variety of applications at the Savannah River Site (SRS). Emergency response dispersion models available at SRS use the space and time-dependent meteorological data provided by this model to supplement local and regional observations. Output from the model is also used locally to aid in forecasting at SRS, and regionally in providing forecasts of the potential time and location of hurricane landfall within the southeast United States

    A theoretical model simulating the simultaneous heat and mass transfer which takes place during the desublimation of a gas to a solid is presented. Desublimer column loading profiles to experimentally verify the model were obtained using a gamma scintillation technique. The data indicate that, if the physical parameters of the desublimed frost material are known, the model can accurately predict the desublimation phenomenon. The usefulness of the model in different engineering applications is also addressed

    Gross, Thilo

    2009-01-01

    With adaptive, complex networks, the evolution of the network topology and the dynamical processes on the network are equally important and often fundamentally entangled. Recent research has shown that such networks can exhibit a plethora of new phenomena which are ultimately required to describe many real-world networks. Some of those phenomena include robust self-organization towards dynamical criticality, formation of complex global topologies based on simple, local rules, and the spontaneous division of "labor" in which an initially homogenous population of network nodes self-organizes into functionally distinct classes. These are just a few. This book is a state-of-the-art survey of those unique networks. In it, leading researchers set out to define the future scope and direction of some of the most advanced developments in the vast field of complex network science and its applications.

    1997-09-01

    The application of analytical light scattering techniques for virtual prototyping the optical performance of paint coatings provides an effective tool for optimizing paint design for specific optical requirements. This paper describes the phenomenological basis for the scattering coatings computer aided design (ScatCad) code. The ScatCad code predicts the bidirectional reflectance distribution function (BRDF) and the hemispherical directional reflectance (HDR) of pigmented paint coatings for the purpose of coating design optimization. The code uses techniques for computing the pigment single scattering phase function, multiple scattering radiative transfer, and rough surface scattering to calculate the BRDF and HDR based on the fundamental optical properties of the pigment(s) and binder, pigment number density and size distribution, and surface roughness of the binder-interface and substrate. This is a significant enhancement to the two- flux, Kubelka-Munk analysis that has traditionally been used in the coatings industry. Example calculations and comparison with measurements are also presented.

    Computer tomography (CT) is today a very important non-invasive imaging tool for medical diagnostics. Despite the non-negligible radiation doses of patients and medical personal certain diagnostic questions can only be answered using CT methods. Recent developments adding a second radiation source and a second detector (dual-source CT) allow the imaging the heart beat due to an improved acquisition time. Operation of the X-ray tubes with different voltages (dual-energy) and appropriate data processing methods allow extended information on the tissue composition, pathological structures and improved visualization of lesions. The contribution covers the basic physical background of this technology and is focused on applications, as for instance CT-guided angiography.

    Gianotti, Patricia

    2010-03-01

    This article offers a perspective and a summary of Jack Danielian's (2010) Horneyan training model, highlighting the benefits of a meta-psychological approach for analysts in training and seasoned practitioners alike. To help illustrate the complexity of Karen Horney's views of character structure and character pathology, this article presents a model that reflects the dynamic tensions at play within individuals with narcissistic issues. It suggests that therapeutic listening can be tracked and that thematic material unfolds in a somewhat predictable, sequential, yet altogether systemic manner. Listening is not just art or intuition, nor is it merely interpretation of content based on a theoretical framework. It represents a way of holding the dialectic tension between conscious and unconscious, syntonic and dystonic. If we can better track these dynamic tensions, we can better anticipate and hopefully avoid clinical ruptures through the acting out of negative transference.

  12. Fuzzy Stochastic Optimization Theory, Models and Applications

    CERN Document Server

    Wang, Shuming

    2012-01-01

    Covering in detail both theoretical and practical perspectives, this book is a self-contained and systematic depiction of current fuzzy stochastic optimization that deploys the fuzzy random variable as a core mathematical tool to model the integrated fuzzy random uncertainty. It proceeds in an orderly fashion from the requisite theoretical aspects of the fuzzy random variable to fuzzy stochastic optimization models and their real-life case studies.   The volume reflects the fact that randomness and fuzziness (or vagueness) are two major sources of uncertainty in the real world, with significant implications in a number of settings. In industrial engineering, management and economics, the chances are high that decision makers will be confronted with information that is simultaneously probabilistically uncertain and fuzzily imprecise, and optimization in the form of a decision must be made in an environment that is doubly uncertain, characterized by a co-occurrence of randomness and fuzziness. This book begins...

  13. Atmospheric dispersion models for environmental pollution applications

    International Nuclear Information System (INIS)

    Gifford, F.A.

    1976-01-01

    Pollutants are introduced into the air by many of man's activities. The potentially harmful effects these can cause are, broadly speaking, of two kinds: long-term, possibly large-scale and wide-spread chronic effects, including long-term effects on the earth's climate; and acute, short-term effects such as those associated with urban air pollution. This section is concerned with mathematical cloud or plume models describing the role of the atmosphere, primarily in relation to the second of these, the acute effects of air pollution, i.e., those arising from comparatively high concentration levels. The need for such air pollution modeling studies has increased spectacularly as a result of the National Environmental Policy Act of 1968 and, especially, two key court decisions; the Calvert Cliffs decision, and the Sierra Club ruling on environmental non-degradation

    Klein-Hessling, W.; Roewekamp, M.; Allelein, H.J.

    2001-01-01

    For the assessment of the efficiency of severe accident management measures the simulation of severe accident development, progression and potential consequences in containments of nuclear power plants is required under conditions as realistic as possible. Therefore, the containment code item (COCOSYS) has been developed by GRS. The main objective is to provide a code system on the basis of mechanistic models for the comprehensive simulation of all relevant processes and plant states during severe accidents in the containment of light water reactors also covering the design basis accidents. In this context the simulation of oil and cable fires is of high priority. These processes strongly depend on the thermal hydraulic boundary conditions. An input-definition of the pyrolysis rate by the user is not consistent with the philosophy of COCOSYS. Therefore, a first attempt has been made for the code internal simulation of the pyrolysis rate and the following combustion process for oil and cable fires. The oil fire model used has been tested against the HDR E41.7 experiment. Because the cable fire model is still under development, a so-called 'simplified cable burning' model has been implemented in COCOSYS and tested against the HDR E42 cable fire experiments. Furthermore, in the frame of the bilateral (between German and Ukrainian government) project INT9131 in the field of fire safety at nuclear power plants (NPP), an exemplary fire hazard analysis (FHA) has been carried out for the cable spreading rooms below the unit control room of a VVER-1000/W-320 type reference plant.

    1998-01-01

    In order to make on-line risk monitoring application of Probabilistic Risk Assessment more complete and realistic, a special attention need to be dedicated to initiating events modeling. Two different issues are of special importance: one is how to model initiating events frequency according to current plant configuration (equipment alignment and out of service status) and operating condition (weather and various activities), and the second is how to preserve dependencies between initiating events model and rest of PRA model. First, the paper will discuss how initiating events can be treated in on-line risk monitoring application. Second, practical example of initiating events modeling in EPRI's Equipment Out of Service on-line monitoring tool will be presented. Gains from application and possible improvements will be discussed in conclusion. (author)

    Full Text Available Classification model of support vector machine (SVM overcomes the problem of a big number of samples. But the kernel parameter and the punishment factor have great influence on the quality of SVM model. Particle swarm optimization (PSO is an evolutionary search algorithm based on the swarm intelligence, which is suitable for parameter optimization. Accordingly, a nonlinear inertia convergence classification model (NICCM is proposed after the nonlinear inertia convergence (NICPSO is developed in this paper. The velocity of NICPSO is firstly defined as the weighted velocity of the inertia PSO, and the inertia factor is selected to be a nonlinear function. NICPSO is used to optimize the kernel parameter and a punishment factor of SVM. Then, NICCM classifier is trained by using the optical punishment factor and the optical kernel parameter that comes from the optimal particle. Finally, NICCM is applied to the classification of the normal state and fault states of online power cable. It is experimentally proved that the iteration number for the proposed NICPSO to reach the optimal position decreases from 15 to 5 compared with PSO; the training duration is decreased by 0.0052 s and the recognition precision is increased by 4.12% compared with SVM.

  1. Modeling protein structures: construction and their applications.

    Science.gov (United States)

    Ring, C S; Cohen, F E

    1993-06-01

    Although no general solution to the protein folding problem exists, the three-dimensional structures of proteins are being successfully predicted when experimentally derived constraints are used in conjunction with heuristic methods. In the case of interleukin-4, mutagenesis data and CD spectroscopy were instrumental in the accurate assignment of secondary structure. In addition, the tertiary structure was highly constrained by six cysteines separated by many residues that formed three disulfide bridges. Although the correct structure was a member of a short list of plausible structures, the "best" structure was the topological enantiomer of the experimentally determined conformation. For many proteases, other experimentally derived structures can be used as templates to identify the secondary structure elements. In a procedure called modeling by homology, the structure of a known protein is used as a scaffold to predict the structure of another related protein. This method has been used to model a serine and a cysteine protease that are important in the schistosome and malarial life cycles, respectively. The model structures were then used to identify putative small molecule enzyme inhibitors computationally. Experiments confirm that some of these nonpeptidic compounds are active at concentrations of less than 10 microM.

    2012-04-01

    Telepathology, the distant service component of digital pathology, is a growth industry. The word "telepathology" was introduced into the English Language in 1986. Initially, two different, competing imaging modalities were used for telepathology. These were dynamic (real time) robotic telepathology and static image (store-and-forward) telepathology. In 1989, a hybrid dynamic robotic/static image telepathology system was developed in Norway. This hybrid imaging system bundled these two primary pathology imaging modalities into a single multi-modality pathology imaging system. Similar hybrid systems were subsequently developed and marketed in other countries as well. It is noteworthy that hybrid dynamic robotic/static image telepathology systems provided the infrastructure for the first truly sustainable telepathology services. Since then, impressive progress has been made in developing another telepathology technology, so-called "virtual microscopy" telepathology (also called "whole slide image" telepathology or "WSI" telepathology). Over the past decade, WSI has appeared to be emerging as the preferred digital telepathology digital imaging modality. However, recently, there has been a re-emergence of interest in dynamic-robotic telepathology driven, in part, by concerns over the lack of a means for up-and-down focusing (i.e., Z-axis focusing) using early WSI processors. In 2010, the initial two U.S. patents for robotic telepathology (issued in 1993 and 1994) expired enabling many digital pathology equipment companies to incorporate dynamic-robotic telepathology modules into their WSI products for the first time. The dynamic-robotic telepathology module provided a solution to the up-and-down focusing issue. WSI and dynamic robotic telepathology are now, rapidly, being bundled into a new class of telepathology/digital pathology imaging system, the "WSI-enhanced dynamic robotic telepathology system". To date, six major WSI processor equipment companies have embraced the approach and developed WSI-enhanced dynamic-robotic digital telepathology systems, marketed under a variety of labels. Successful commercialization of such systems could help overcome the current resistance of some pathologists to incorporate digital pathology, and telepathology, into their routine and esoteric laboratory services. Also, WSI-enhanced dynamic robotic telepathology could be useful for providing general pathology and subspecialty pathology services to many of the world's underserved populations in the decades ahead. This could become an important enabler for the delivery of patient-centered healthcare in the future. © 2012 The Authors APMIS © 2012 APMIS.

  3. Applications of GARCH models to energy commodities

    Science.gov (United States)

    Humphreys, H. Brett

    This thesis uses GARCH methods to examine different aspects of the energy markets. The first part of the thesis examines seasonality in the variance. This study modifies the standard univariate GARCH models to test for seasonal components in both the constant and the persistence in natural gas, heating oil and soybeans. These commodities exhibit seasonal price movements and, therefore, may exhibit seasonal variances. In addition, the heating oil model is tested for a structural change in variance during the Gulf War. The results indicate the presence of an annual seasonal component in the persistence for all commodities. Out-of-sample volatility forecasting for natural gas outperforms standard forecasts. The second part of this thesis uses a multivariate GARCH model to examine volatility spillovers within the crude oil forward curve and between the London and New York crude oil futures markets. Using these results the effect of spillovers on dynamic hedging is examined. In addition, this research examines cointegration within the oil markets using investable returns rather than fixed prices. The results indicate the presence of strong volatility spillovers between both markets, weak spillovers from the front of the forward curve to the rest of the curve, and cointegration between the long term oil price on the two markets. The spillover dynamic hedge models lead to a marginal benefit in terms of variance reduction, but a substantial decrease in the variability of the dynamic hedge; thereby decreasing the transactions costs associated with the hedge. The final portion of the thesis uses portfolio theory to demonstrate how the energy mix consumed in the United States could be chosen given a national goal to reduce the risks to the domestic macroeconomy of unanticipated energy price shocks. An efficient portfolio frontier of U.S. energy consumption is constructed using a covariance matrix estimated with GARCH models. The results indicate that while the electric

Using the model, we analyze the synergistic effect of the functional requirements (data collection from the human body and transferring it to the top level and non-functional requirements (trade-offs between energy-security-environmental factors, treated as Quality-of-Service (QoS. We use feature models to represent the requirements at the earliest stage for the analysis and describe a model-driven methodology to design the possible BAN applications. Firstly, we specify the requirements as the problem domain (PD variability model for the BAN applications. Next, we introduce the generative technology (meta-programming as the solution domain (SD and the mapping procedure to map the PD feature-based variability model onto the SD feature model. Finally, we create an executable meta-specification that represents the BAN functionality to describe the variability of the problem domain though transformations. The meta-specification (along with the meta-language processor is a software generator for multiple BAN-oriented applications. We validate the methodology with experiments and a case study to generate a family of programs for the BAN sensor controllers. This enables to obtain the adequate measure of QoS efficiently through the interactive adjustment of the meta-parameter values and re-generation process for the concrete BAN application.

    Watershed models can be used to simulate natural and human-altered processes including the flow of water and associated transport of sediment, chemicals, nutrients, and microbial organisms within a watershed. Simulation of these processes is useful for addressing a wide range of water-resource challenges, such as quantifying changes in water availability over time, understanding the effects of development and land-use changes on water resources, quantifying changes in constituent loads and yields over time, and quantifying aquifer recharge temporally and spatially throughout a watershed.

    Watershed water environment pollution model is the important tool for studying watershed environmental problems. Through the quantitative description of the complicated pollution processes of whole watershed system and its parts, the model can identify the main sources and migration pathways of pollutants, estimate the pollutant loadings, and evaluate their impacts on water environment, providing a basis for watershed planning and management. This paper reviewed the watershed water environment models widely applied at home and abroad, with the focuses on the models of pollutants loading (GWLF and PLOAD), water quality of received water bodies (QUAL2E and WASP), and the watershed models integrated pollutant loadings and water quality (HSPF, SWAT, AGNPS, AnnAGNPS, and SWMM), and introduced the structures, principles, and main characteristics as well as the limitations in practical applications of these models. The other models of water quality (CE-QUAL-W2, EFDC, and AQUATOX) and watershed models (GLEAMS and MIKE SHE) were also briefly introduced. Through the case analysis on the applications of single model and integrated models, the development trend and application prospect of the watershed water environment pollution models were discussed.

    Neuhauser, K.S.; Kanipe, R.L.; Weiner, R.F.

    1998-01-01

    A number of environmental impact analyzes with the RADTRAN computer code have shown that dose to persons at stops is one of the largest components of incident-free dose during overland carriage of spent fuel and other radioactive materials. The input data used in these analyses were taken from a 1983 study that reports actual observations of spent fuel shipments by truck. Early RADTRAN stop models, however, were insufficiently flexible to take advantage of the detailed information in the study. A more recent study of gasoline service stations that specialize in servicing large trucks, which are the most likely stop locations for shipments of Type B packages in the United States, has provided additional, detailed data on refueling/meal stops. The RADTRAN 5 computer code for transportation risk analysis allows exposures at stops to be more fully modelled than have previous releases of the code and is able to take advantage of detailed data. It is the intent of this paper first to compare results from RADTRAN 4 and RADTRAN 5 for the old, low-resolution form of input data, and then to demonstrate what effect the new data and input format have on stop-dose estimates for an individual stop and for a hypothetical shipment route. Finally, these estimated public doses will be contrasted with doses calculated for a special population group-inspectors. (authors)

    A number of environmental impact analyses with the RADTRAN computer code have shown that dose to persons at stops is one of the largest components of incident-free dose during overland carriage of spent fuel and other radioactive materials (e.g., USDOE, 1994). The input data used in these analyses were taken from a 1983 study that reports actual observations of spent fuel shipments by truck. Early RADTRAN stop models, however, were insufficiently flexible to take advantage of the detailed information in the study. A more recent study of gasoline service stations that specialize in servicing large trucks, which are the most likely stop locations for shipments of Type B packages in the United States, has provided additional, detailed data on refueling/meal stops.

    Full Text Available This experiment was conducted to determine the equations relating the Hue digital values of the fruits surface of the oil palm with maturity stage of the fruit in plantation. The FFB images were zoomed and captured using Nikon digital camera, and the calculation of Hue was determined using the highest frequency of the value for R, G, and B color components from histogram analysis software. New procedure in monitoring the image pixel value for oil palm fruit color surface in real-time growth maturity was developed. The estimation of day harvesting prediction was calculated based on developed model of relationships for Hue values with mesocarp oil content. The simulation model is regressed and predicts the day of harvesting or a number of days before harvest of FFB. The result from experimenting on mesocarp oil content can be used for real-time oil content determination of MPOB color meter. The graph to determine the day of harvesting the FFB was presented in this research. The oil was found to start developing in mesocarp fruit at 65 days before fruit at ripe maturity stage of 75% oil to dry mesocarp.

    This report describes specific GDSA activities in fiscal year 2015 (FY2015) toward the development of the enhanced disposal system modeling and analysis capability for geologic disposal of nuclear waste. The GDSA framework employs the PFLOTRAN thermal-hydrologic-chemical multi-physics code (Hammond et al., 2011) and the Dakota uncertainty sampling and propagation code (Adams et al., 2013). Each code is designed for massively-parallel processing in a high-performance computing (HPC) environment. Multi-physics representations in PFLOTRAN are used to simulate various coupled processes including heat flow, fluid flow, waste dissolution, radionuclide release, radionuclide decay and ingrowth, precipitation and dissolution of secondary phases, and radionuclide transport through the engineered barriers and natural geologic barriers to a well location in an overlying or underlying aquifer. Dakota is used to generate sets of representative realizations and to analyze parameter sensitivity.

    This work consist of the implementation and evaluation of elastic alignment algorithms of biomedical images, which were taken at thorax level and simulated with the 4D NCAT digital phantom. Radial Basis Functions spatial transformations (RBF), a kind of spline, which allows carrying out not only global rigid deformations but also local elastic ones were applied, using a point-matching method. The applied functions were: Thin Plate Spline (TPS), Multiquadric (MQ) Gaussian and B-Spline, which were evaluated and compared by means of calculating the Target Registration Error and similarity measures between the registered images (the squared sum of intensity differences (SSD) and correlation coefficient (CC)). In order to value the user incurred error in the point-matching and segmentation tasks, two algorithms were also designed that calculate the Fiduciary Localization Error. TPS and MQ were demonstrated to have better performance than the others. It was proved RBF represent an adequate model for approximating the thorax deformable behaviour. Validation algorithms showed the user error was not significant

    The design of integrated controls for a complex system like a wind turbine relies on a system model in an explicit format, e.g., state-space format. Current wind turbine codes focus on turbine simulation and not on system characterization, which is desired for controls design as well as applications like operating turbine model analysis, optimal design, and aeroelastic stability analysis. This paper reviews structural modeling that comprises three major steps: formation of component equations, assembly into system equations, and linearization

    Full Text Available The Solomon Islands Truth and Reconciliation Commission (TRC was the first TRC in the Pacific Islands. Its goals and activities – truth-seeking, reconciliation and the production of a report with a narrative of the conflict that focused on human rights violations – reflect the normative values of global transitional justice discourses. In this paper I draw on interviews with former staff of the TRC and my own experiences of working for the TRC to explore the implications of importing international transitional justice mechanisms into the local Solomon Islands context, and to draw attention to the cultural limitations of truth-telling. I argue that in order for peacebuilding tools to be effective in Solomon Islands, a strong commitment to, and understanding of, local context is required; transitional justice mechanisms must resonate with local understandings and practices of conflict resolution and peacemaking. The TRC has the potential to play a positive role in building peace in Solomon Islands if it is viewed as a component of an ongoing process.Truth and memory alone will not bring about justice, reconciliation or peace; the memories and truths that are collected and produced by the TRC ought to be used for future action, addressing ongoing injustices and grievances.

  6. Restoring relationship between former genocide perpetrators and survivors of genocide against Tutsi in Rwanda through reconciliation villages

    Mafeza, F.

    2013-06-01

    Full Text Available Throughout the 20th century, genocide has claimed many lives across the world. In Rwanda, the Genocide against the Tutsi was perpetrated with unprecedented violence and took the lives of more than one million. In the aftermath of the genocide, the interpersonal relationships between genocide survivors and former genocide perpetrators as well as their respective family members was undermined. Through Prison Fellowship Rwanda, former genocide perpetrators and survivors of genocide were brought together in reconciliation villages as a way of restoring their relationships. Drawing on interviews and focus group discussion with members of five reconciliation villages, this study uses a qualitative approach to examine how these villages contribute to the restoration of relationship between conflicting parties in the aftermath of the genocide against the Tutsi in Rwanda. The findings indicate that living together in reconciliation village combined with economic joint activities provided a favorable space in which negative-dehumanizing attitudes were overcome, while positive-re-humanizing attitudes were fostered. Additionally, the village offered members an opportunity for communication, reduced prejudice and fear among them, and generated trust in the community.

    2014-01-01

    Describe the types of medication discrepancies that persist despite pharmacist-led medication reconciliation using the primary care electronic medical record (EMR). Observational case series study of established patients from an urban, indigent care clinic. Medication reconciliation was conducted immediately prior to the physician visit at baseline and return visit. Main outcome measures included: frequency, types, and reasons for discrepancies, patient knowledge, and adherence. There was a 14.5% reduction in the number of patients with a discrepancy and the frequency of discrepancies was reduced by 7.3%. The rate of medication discrepancies in the chart was reduced by 31.3%. The most common type of discrepancy that persisted at follow up were medications listed on the chart that the patient stopped taking. Discrepancies were more likely to persist in Caucasian subjects when compared to African Americans. While pharmacist led medication reconciliation appears effective at reducing the likelihood of a medication discrepancy in the EMR, challenges persist in maintaining this accuracy specifically as it relates to patient driven changes to the medication regimen.

    Adverse drug events (ADEs) are a major cause of morbidity and mortality, with more than 50% of ADEs being preventable. Adverse Drug Reactions (ADRs) are typically the result of an incomplete medication history, prescribing or dispensing error, as well as over- or under-use of prescribed pharmacotherapy. Medication reconciliation is the process of creating the most accurate list of medications a patient is taking and subsequently comparing the list against the different transitions of care. It is used to reduce medication discrepancies, and thereby ultimately decreasing ADEs. However, little is known about medicine reconciliation activities among public hospitals in South Africa. Prospective quantitative, descriptive design among Internal and Surgical wards in a leading public hospital in South Africa. 145 study participants were enrolled. Over 1300 (1329) medicines were reviewed of which there was a significant difference (p = 0.006) when comparing the medications that the patient was taking before or during hospitalisation. A total of 552 (41.53%) interventions were undertaken and the majority of patients had at least 3.96 medication discrepancies. The most common intervention upon admission was transcribing the home medication onto the hospital prescription (65.2%) followed by medication duplication (13.44%). During patient's hospital stay, interventions included patient counselling (32.5%) and stopping the previous treatment (37.5%). To ensure continuity of patient care, medication reconciliation should be implemented throughout patients' hospital stay. This involves all key professionals in hospitals.

  9. Organizational Initiatives for Promoting Employee Work-Life Reconciliation Over the Life Course. A Systematic Review of Intervention Studies

    2016-10-01

    Full Text Available This review aimed to explore the initiatives, interventions, and experiments implemented by employing organizations and designed to support the work-life reconciliation at workplaces, and the effects of these actions on employees’ well-being at work. A systematic literature review was conducted on the basis of a search in PsycInfo, ERIC, and the ISI Web of Science database of Social Sciences between January 2000 and May 2015. Those studies were included in which either organizational or individual-level initiatives, interventions, or experiments were implemented by employers at workplaces in order to promote the work-life reconciliation of their employees. Work-life reconciliation was considered to encompass all life domains and all career stages from early to the end of working career. The content analysis of 11 studies showed that effective employer actions focused on working time, care arrangements, and training for supervisors and employees. Flexibility, in terms of both working time and other arrangements provided for employees, and support from supervisors decreased work-family conflict, improved physical health and job satisfaction, and also reduced the number of absence days and turnover intentions. Overall, very few intervention studies exist investigating the effects of employer-induced work-life initiatives. One should particularly note the conditions under which interventions are most successful, since many contextual and individual-level factors influence the effects of organizational initiatives on employee and organizational outcomes.

    2015-05-01

    In 2012, the New Zealand Government announced a proposal to introduce predictive risk models (PRMs) to help professionals identify and assess children at risk of abuse or neglect as part of a preventive early intervention strategy, subject to further feasibility study and trialing. The purpose of this study is to examine technical feasibility and predictive validity of the proposal, focusing on a PRM that would draw on population-wide linked administrative data to identify newborn children who are at high priority for intensive preventive services. Data analysis was conducted in 2013 based on data collected in 2000-2012. A PRM was developed using data for children born in 2010 and externally validated for children born in 2007, examining outcomes to age 5 years. Performance of the PRM in predicting administratively recorded substantiations of maltreatment was good compared to the performance of other tools reviewed in the literature, both overall, and for indigenous Māori children. Some, but not all, of the children who go on to have recorded substantiations of maltreatment could be identified early using PRMs. PRMs should be considered as a potential complement to, rather than a replacement for, professional judgment. Trials are needed to establish whether risks can be mitigated and PRMs can make a positive contribution to frontline practice, engagement in preventive services, and outcomes for children. Deciding whether to proceed to trial requires balancing a range of considerations, including ethical and privacy risks and the risk of compounding surveillance bias. Crown Copyright © 2015.

    2016-01-01

    Sequential sampling models assume that people make speeded decisions by gradually accumulating noisy information until a threshold of evidence is reached. In cognitive science, one such model--the diffusion decision model--is now regularly used to decompose task performance into underlying processes such as the quality of information processing, response caution, and a priori bias. In the cognitive neurosciences, the diffusion decision model has recently been adopted as a quantitative tool to study the neural basis of decision making under time pressure. We present a selective overview of several recent applications and extensions of the diffusion decision model in the cognitive neurosciences.

    Full Text Available For Enterprise Resource Planning (ERP systems such as SAP R/3 or IBM SanFrancisco, the tailoring of reference models for customizing the ERP systems to specific organizational contexts is an established approach. In this paper, we present a methodology that uses such reference models as a starting point for a top-down integration of enterprise applications. The re-engineered models of legacy systems are individually linked via cross-mapping specifications to the forward-engineered reference model's specification. The actual linking of reference and legacy models is done with a methodology for connecting (new business objects with (old legacy systems.

  14. An investigation of modelling and design for software service applications.

    Anjum, Maria; Budgen, David

    2017-01-01

    Software services offer the opportunity to use a component-based approach for the design of applications. However, this needs a deeper understanding of how to develop service-based applications in a systematic manner, and of the set of properties that need to be included in the 'design model'. We have used a realistic application to explore systematically how service-based designs can be created and described. We first identified the key properties of an SOA (service oriented architecture) and then undertook a single-case case study to explore its use in the development of a design for a large-scale application in energy engineering, modelling this with existing notations wherever possible. We evaluated the resulting design model using two walkthroughs with both domain and application experts. We were able to successfully develop a design model around the ten properties identified, and to describe it by adapting existing design notations. A component-based approach to designing such systems does appear to be feasible. However, it needs the assistance of a more integrated set of notations for describing the resulting design model.

  15. Reconciling uncertainties in integrated science and policy models: Applications to global climate change

    Energy Technology Data Exchange (ETDEWEB)

    Kandlikar, Milind [Carnegie Mellon Univ., Pittsburgh, PA (United States)

    1994-12-01

    In this thesis tools of data reconciliation are used to integrate available information into scientific and policy models of greenhouse gases. The role of uncertainties in scientific and policy models of global climate change is examined, and implications for global change policy are drawn. Methane is the second most important greenhouse gas. Global sources and sinks of methane have significant uncertainties. A chance constrained methodology was developed and used to perform inversions on the global methane cycle. Budgets of methane that are consistent with source fluxes, isotopic and ice core measurements were determined. While it is not possible to come up with a single budget for CH{sub 4}, performing the calculation with a number of sets of assumed priors suggests a convergence in the allowed range for sources. In some cases -- wetlands (70-130 Tg/yr), rice paddies (60-125 Tg/yr) a significant reduction in the uncertainty of the source estimate is achieved. Our results compare favorably with the most recent measurements of flux estimates. For comparison, a similar analysis using bayes monte carlo simulation was performed. The question of the missing sink for carbon remains unresolved. Two analyses that attempt to quantify the missing sink were performed. First, a steady state analysis of the carbon cycle was used to determine the pre-industrial inter-hemispheric carbon concentration gradient. Second, a full blown dynamic inversion of the carbon cycle was performed. An advection diffusion ocean model with surface chemistry, coupled to box models of the atmosphere and the biosphere was inverted to fit available measurements of {sup 12}C and {sup 14}C carbon isotopes using Differential-Algebraic Optimization. The model effectively suggests that the {open_quotes}missing{close_quotes} sink for carbon is hiding in the biosphere. Scenario dependent trace gas indices were calculated for CH{sub 4}, N{sub 2}O, HCFC-22.

  16. Numerical simulation of the optimal two-mode attacks for two-way continuous-variable quantum cryptography in reverse reconciliation

    International Nuclear Information System (INIS)

    Zhang, Yichen; Zhao, Yijia; Yu, Song; Li, Zhengyu; Guo, Hong

    2017-01-01

    We analyze the security of the two-way continuous-variable quantum key distribution protocol in reverse reconciliation against general two-mode attacks, which represent all accessible attacks at fixed channel parameters. Rather than against one specific attack model, the expression of secret key rates of the two-way protocol are derived against all accessible attack models. It is found that there is an optimal two-mode attack to minimize the performance of the protocol in terms of both secret key rates and maximal transmission distances. We identify the optimal two-mode attack, give the specific attack model of the optimal two-mode attack and show the performance of the two-way protocol against the optimal two-mode attack. Even under the optimal two-mode attack, the performances of two-way protocol are still better than the corresponding one-way protocol, which shows the advantage of making double use of the quantum channel and the potential of long-distance secure communication using a two-way protocol.

    Critical care delivery is a complex, expensive, error prone, medical specialty and remains the focal point of major improvement efforts in healthcare delivery. Various modeling and simulation techniques offer unique opportunities to better understand the interactions between clinical physiology and care delivery. The novel insights gained from the systems perspective can then be used to develop and test new treatment strategies and make critical care delivery more efficient and effective. However, modeling and simulation applications in critical care remain underutilized. This article provides an overview of major computer-based simulation techniques as applied to critical care medicine. We provide three application examples of different simulation techniques, including a) pathophysiological model of acute lung injury, b) process modeling of critical care delivery, and c) an agent-based model to study interaction between pathophysiology and healthcare delivery. Finally, we identify certain challenges to, and opportunities for, future research in the area.

    Theodorou, Doros; Stefaneas, Petros; Kauffman, Louis

    2017-01-01

    This interdisciplinary book covers a wide range of subjects, from pure mathematics (knots, braids, homotopy theory, number theory) to more applied mathematics (cryptography, algebraic specification of algorithms, dynamical systems) and concrete applications (modeling of polymers and ionic liquids, video, music and medical imaging). The main mathematical focus throughout the book is on algebraic modeling with particular emphasis on braid groups. The research methods include algebraic modeling using topological structures, such as knots, 3-manifolds, classical homotopy groups, and braid groups. The applications address the simulation of polymer chains and ionic liquids, as well as the modeling of natural phenomena via topological surgery. The treatment of computational structures, including finite fields and cryptography, focuses on the development of novel techniques. These techniques can be applied to the design of algebraic specifications for systems modeling and verification. This book is the outcome of a w...

  1. Atmospheric disturbance modelling requirements for flying qualities applications

    Moorhouse, D. J.

    1978-01-01

    Flying qualities are defined as those airplane characteristics which govern the ease or precision with which the pilot can accomplish the mission. Some atmospheric disturbance modelling requirements for aircraft flying qualities applications are reviewed. It is concluded that some simplifications are justified in identifying the primary influence on aircraft response and pilot control. It is recommended that a universal environmental model be developed, which could form the reference for different applications. This model should include the latest information on winds, turbulence, gusts, visibility, icing and precipitation. A chosen model would be kept by a national agency and updated regularly by feedback from users. A user manual is believed to be an essential part of such a model.

  2. Reviewing model application to support animal health decision making.

    Singer, Alexander; Salman, Mo; Thulke, Hans-Hermann

    2011-04-01

    Animal health is of societal importance as it affects human welfare, and anthropogenic interests shape decision making to assure animal health. Scientific advice to support decision making is manifold. Modelling, as one piece of the scientific toolbox, is appreciated for its ability to describe and structure data, to give insight in complex processes and to predict future outcome. In this paper we study the application of scientific modelling to support practical animal health decisions. We reviewed the 35 animal health related scientific opinions adopted by the Animal Health and Animal Welfare Panel of the European Food Safety Authority (EFSA). Thirteen of these documents were based on the application of models. The review took two viewpoints, the decision maker's need and the modeller's approach. In the reviewed material three types of modelling questions were addressed by four specific model types. The correspondence between tasks and models underpinned the importance of the modelling question in triggering the modelling approach. End point quantifications were the dominating request from decision makers, implying that prediction of risk is a major need. However, due to knowledge gaps corresponding modelling studies often shed away from providing exact numbers. Instead, comparative scenario analyses were performed, furthering the understanding of the decision problem and effects of alternative management options. In conclusion, the most adequate scientific support for decision making - including available modelling capacity - might be expected if the required advice is clearly stated.

  3. Hydraulic modeling development and application in water resources engineering

    Science.gov (United States)

    Simoes, Francisco J.; Yang, Chih Ted; Wang, Lawrence K.

    2015-01-01

    The use of modeling has become widespread in water resources engineering and science to study rivers, lakes, estuaries, and coastal regions. For example, computer models are commonly used to forecast anthropogenic effects on the environment, and to help provide advanced mitigation measures against catastrophic events such as natural and dam-break floods. Linking hydraulic models to vegetation and habitat models has expanded their use in multidisciplinary applications to the riparian corridor. Implementation of these models in software packages on personal desktop computers has made them accessible to the general engineering community, and their use has been popularized by the need of minimal training due to intuitive graphical user interface front ends. Models are, however, complex and nontrivial, to the extent that even common terminology is sometimes ambiguous and often applied incorrectly. In fact, many efforts are currently under way in order to standardize terminology and offer guidelines for good practice, but none has yet reached unanimous acceptance. This chapter provides a view of the elements involved in modeling surface flows for the application in environmental water resources engineering. It presents the concepts and steps necessary for rational model development and use by starting with the exploration of the ideas involved in defining a model. Tangible form of those ideas is provided by the development of a mathematical and corresponding numerical hydraulic model, which is given with a substantial amount of detail. The issues of model deployment in a practical and productive work environment are also addressed. The chapter ends by presenting a few model applications highlighting the need for good quality control in model validation.

    Full Text Available A complex autoregressive model was established based on the mathematic derivation of the least squares for the complex number domain which is referred to as the complex least squares. The model is different from the conventional way that the real number and the imaginary number are separately calculated. An application of this new model shows a better forecast than forecasts from other conventional statistical models, in predicting monthly temperature anomalies in July at 160 meteorological stations in mainland China. The conventional statistical models include an autoregressive model, where the real number and the imaginary number are separately disposed, an autoregressive model in the real number domain, and a persistence-forecast model.

    Whenever a technical task is to be solved with the help of a database application and uncertainties regarding the structure, scope or level of detail of the data model exist (either currently or in the future) the use of a generic database application can reduce considerably the cost of implementation and maintenance. Simultaneously the approach described in this contribution permits the operation with different views on the data and even finding and defining new views which had not been considered before. The prerequisite for this is that the preliminary information (structure as well as data) stored into the generic application matches the intended use. In this case, parts of the generic model developed with the generic approach can be reused and according efforts for a major rebuild can be saved. This significantly reduces the development time. At the same time flexibility is achieved concerning the environmental data model, which is not given in the context of conventional developments. (orig.)

    One of the challenges for characterizing and modeling realistic multimedia applications is the lack of access to source codes. On-chip performance counters effectively resolve this problem by monitoring run-time behaviors at the instruction-level. This paper presents a novel technique of characterizing and modeling workloads at the instruction level for realistic multimedia applications using hardware performance counters. A variety of instruction counts are collected from some multimedia applications, such as RealPlayer, GSM Vocoder, MPEG encoder/decoder, and speech synthesizer. These instruction counts can be used to form a set of abstract characteristic parameters directly related to a processor`s architectural features. Based on microprocessor architectural constraints and these calculated abstract parameters, the architectural performance bottleneck for a specific application can be estimated. Meanwhile, the bottleneck estimation can provide suggestions about viable architectural/functional improvement for certain workloads. The biggest advantage of this new characterization technique is a better understanding of processor utilization efficiency and architectural bottleneck for each application. This technique also provides predictive insight of future architectural enhancements and their affect on current codes. In this paper the authors also attempt to model architectural effect on processor utilization without memory influence. They derive formulas for calculating CPI{sub 0}, CPI without memory effect, and they quantify utilization of architectural parameters. These equations are architecturally diagnostic and predictive in nature. Results provide promise in code characterization, and empirical/analytical modeling.

  10. Animal models of enterovirus 71 infection: applications and limitations

    Science.gov (United States)

    2014-01-01

    Human enterovirus 71 (EV71) has emerged as a neuroinvasive virus that is responsible for several outbreaks in the Asia-Pacific region over the past 15 years. Appropriate animal models are needed to understand EV71 neuropathogenesis better and to facilitate the development of effective vaccines and drugs. Non-human primate models have been used to characterize and evaluate the neurovirulence of EV71 after the early outbreaks in late 1990s. However, these models were not suitable for assessing the neurovirulence level of the virus and were associated with ethical and economic difficulties in terms of broad application. Several strategies have been applied to develop mouse models of EV71 infection, including strategies that employ virus adaption and immunodeficient hosts. Although these mouse models do not closely mimic human disease, they have been applied to determine the pathogenesis of and treatment and prevention of the disease. EV71 receptor-transgenic mouse models have recently been developed and have significantly advanced our understanding of the biological features of the virus and the host-parasite interactions. Overall, each of these models has advantages and disadvantages, and these models are differentially suited for studies of EV71 pathogenesis and/or the pre-clinical testing of antiviral drugs and vaccines. In this paper, we review the characteristics, applications and limitation of these EV71 animal models, including non-human primate and mouse models. PMID:24742252

    2013-10-01

    Full Text Available A hybrid energy system (HES is a trending power supply solution for autonomous devices. With the help of an accurate system model, the HES development will be efficient and oriented. In spite of various precise unit models, a HES system is hardly developed. This paper proposes a system modelling approach, which applies the power flux conservation as the governing equation and adapts and modifies unit models of solar cells, piezoelectric generators, a Li-ion battery and a super-capacitor. A generalized power harvest, storage and management strategy is also suggested to adapt to various application scenarios.

    Realising the theoretical electrical characteristics of components through modelling can be carried out using computer-aided design (CAD) simulation tools. If the simulation model provides the expected characteristics, the fabrication process of Monolithic Microwave Integrated Circuit (MMIC) can be performed for experimental verification purposes. Therefore improvements can be suggested before mass fabrication takes place. This research concentrates on development of MMIC technology by providing accurate predictions of the characteristics of MMIC components using an improved Electromagnetic (EM) modelling technique. The knowledge acquired from the modelling and characterisation process in this work can be adopted by circuit designers for various high frequency applications.

  13. Discerning a theological agenda for spatial justice in South Africa: An imperative for sustained reconciliation

    Directory of Open Access Journals (Sweden)

    Stephan de Beer

    2016-11-01

    Full Text Available A spatial turn has occurred in various disciplines over the past decades. This article holds that it has not occurred in a similar decisive manner in theological discourse and not in South Africa in particular. After considering the necessity of a spatial turn and spatial consciousness, the article examines the concept of spatial justice against the backdrop of how injustice was and is spatially expressed in South African cities. Considering the way in which South African cities have evolved since the Native Land Act of 1913 – the segregated and apartheid city and the (postapartheid city – the article then argues that deep and sustained reconciliation will be impossible should current spatial patterns of segregation, exclusion and injustice continue. It advocates theological and ecclesial participation in a national agenda for spatial transformation, to be fleshed out in relation to four interconnected challenges: land, landlessness, housing and home; the ‘creative destruction’ of neighbourhoods, gentrification and the displacement of the poor; participation in city-making (from below and transformative spatial interventions; and close collaboration with social movements working for spatial justice. It concludes by asserting that such a trans- and/or postdisciplinary agenda for spatial justice would participate with the Spirit to mend the oikos of God.

    2016-01-01

    Medicines reconciliation (MR) is an essential process for patient safety, promoting safer use of medicines with effective communication at the interface, particularly when patients are admitted and discharged from hospital. Much of the work on MR has been focussed in secondary care, however, the principles are equally important in primary care. The aim of the work was to test the Scottish Patient Safety in Primary Care (SPSP-PC) MR care bundle and consider scale up and spread across all NHS Greater Glasgow and Clyde (NHS GGC) GP practices. Care bundles are a quality improvement tool which can drive improvement by standardising processes to deliver optimum care. Pilot work and testing began with 5 GP practices in 2011 and was spread to over 200 practices by 2015/16. A care bundle compliance process measure was measured monthly, with practices sampling 10 patients per month. Practices could view their run charts in real time and identify which measures resulted in "non-compliance" and PDSA cycles were promoted to test and implement improvements. Data was collated at NHS GGC level with an aim of 95% compliance with the care bundle by March 2016. MR care bundle compliance started at 40% (5 practices reporting) in 2011 with final data in March 2016 demonstrating 92% compliance (192 practices reporting). A sustained "reliability" of 92-93% across >200 practices has been observed since January 2015. In conclusion, the bundle was implemented by 97% of NHS GGC GP practices and resulted in process improvements.

    2017-08-01

    Full Text Available Genome-wide global detection of genes involved in horizontal gene transfer (HGT remains an active area of research in medical microbiology and evolutionary genomics. Utilizing the explicit evolutionary method of comparing topologies of a total of 154,805 orthologous gene trees against corresponding 16S rRNA “reference” trees, we previously detected a total of 660,894 candidate HGT events in 2,472 completely-sequenced prokaryotic genomes. Here, we report an HGT-index for each individual gene-reference tree pair reconciliation, representing the total number of detected HGT events on the gene tree divided by the total number of genomes (taxa member of that tree. HGT-index is thus a simple measure indicating the sensitivity of prokaryotic genes to participate (or not participate in HGT. Our preliminary list provides HGT-indices for a total of 69,365 genes (detected in >10 and <50% available prokaryotic genomes that are involved in a wide range of biological processes such as metabolism, information, and bacterial response to environment. Identification of horizontally-derived genes is important to combat antibiotic resistance and is a step forward toward reconstructions of improved phylogenies describing the history of life. Our effort is thus expected to benefit ongoing research in the fields of clinical microbiology and evolutionary biology.

  16. Reconciliation Modes. Two Remakes of 60s Films in Contemporary Argentine Cinema

    Directory of Open Access Journals (Sweden)

    Jorge SALA

    2017-06-01

    Full Text Available The article analyzes two contemporary movie remakes of the 60s cinemas in Argentina: Aniceto (Leonardo Favio, 2008 and La patota (Santiago Mitre, 2015. The objective is to explore the transformations and continuities between the source texts and the later subsidiary texts. It tries to recognize the immanent issues, the procedural and pragmatic aspects involved in these rewriting operations. The central hypothesis to be demonstrated proposes that both films generate, through different paths, a reconciliation with the past constructing a perspective through the present. In Aniceto, the conciliation gesture occurs in the form of a synthesis of the two tendencies that characterized Favio’s cinema: a first one associated with the aesthetics of modernity versus the second one, in which the approach to the popular universe and other practices belonging to the mass culture predominates. For its part, the work of Santiago Mitre assembles a film of an Argentinean classic movie maker (Daniel Tinayre under the light of the current cinema. Besides, La patota ties the characteristics of a great commercial production with the structure and aesthetic of the «anomalous cinema».

  17. 'The body remembers': narrating embodied reconciliations of eating disorder and recovery.

    After severe illness, there are stories: narrative strands to suture discontinuities of identities, practices, and lives. But within these narratives of illness and recovery, the body's discontinuities stand apart, striking in the materiality of change, in the tangible multiplicity of bodies - healthy, ill, recovering, recovered - that a person can call one's own. Based on longitudinal research interviews with Israeli women who identified as recovered from long-term eating disorders (fieldwork conducted in 2005-2006 and in 2011), this paper explores how these bodily discontinuities are expressed, drawing particular attention to the narrative role of embodied memory in linking past and present-tense bodies and selves. Embodied memory, as narrated by the participants, is deeply, sometimes surprisingly, embedded in lived experience, imbuing recovered bodies with moments of sensory continuity, the past coming into presence through forms of sensation and perception learned at the height of disorder. Examining narrative moments of sensory remembrance, this paper analyses how participants narrate embodied memory as a mode of reflection, self-protection, and dynamic integration, wherein the experience of disorder informs practices of recovery, and the body becomes a site for the reconciliation of past and present.

    Few studies have explored the impact of using different methods for obtaining accurate medication histories on medication safety. This study was conducted to compare the accuracy and clinical impact of pharmacist medication histories obtained by electronic medical record review (EMRR) alone with those obtained by direct interviews combined with EMRR. This 18-week prospective study included patients who were admitted to the Inpatient Medicine Service at the study institution and who had a pharmacist-conducted medication reconciliation EMRR within 48 hours of hospital admission. A chart review was performed to collect data to determine whether differences existed in the number of discrepancies, recommendations, and medication errors between the EMRR alone group compared to the EMRR combined with the patient interview group. Five hundred thirteen discrepancies were identified with the EMRR group compared to 986 from the combined EMRR and patient interview group (P < .001). Significantly more recommendations were made in the combination interview group compared to the EMRR alone group (260 vs 97; P < .001). Fewer medication errors were identified for the EMRR alone group compared to the combination interview group (55 vs 134; P < .001). The most common errors were omitted medications followed by extra dose/failure to discontinue therapy and wrong dose/frequency errors. Pharmacist-conducted admission medication interviews combined with EMRR can potentially identify harmful medication discrepancies and prevent medication errors.

  19. Homosexual Behavior in Female Mountain Gorillas: Reflection of Dominance, Affiliation, Reconciliation or Arousal?

    Directory of Open Access Journals (Sweden)

    Cyril C Grueter

    Full Text Available Humans are unique among primates for not only engaging in same-sex sexual acts, but also forming homosexual pair bonds. To shed light on the evolutionary origins of homosexuality, data on the occurrence and contexts of same-sex behavior from nonhuman primates may be of particular significance. Homosexual behavior involving females is poorly researched in most primate taxa, exceptions being Japanese macaques, rhesus macaques, Hanuman langurs and bonobos. We present data on homosexual behavior in female mountain gorillas in the Virunga Volcanoes (Rwanda and test four functional hypotheses, namely reconciliation, affiliation, dominance expression and sexual arousal. Homosexual interactions between females involved both ventro-dorsal and ventro-ventral copulations accompanied by vocalizations and courtship displays. The only sociosexual hypothesis that received partial empirical support is the social status hypothesis, i.e., that mounting reaffirms the dominance hierarchy. There is also some limited evidence that same-sex behavior reflects an overall state of arousal or is triggered via a 'pornographic' effect. An adaptive function of female homosexual behavior is not readily apparent, and we tentatively conclude (until a more rigorous test becomes available that it may simply be related to sexual gratification or that it is an evolutionary by-product of an adaptation.

  20. Buried transuranic wastes at ORNL: Review of past estimates and reconciliation with current data

    1997-09-01

    Inventories of buried (generally meaning disposed of) transuranic (TRU) wastes at Oak Ridge National Laboratory (ORNL) have been estimated for site remediation and waste management planning over a period of about two decades. Estimates were required because of inadequate waste characterization and incomplete disposal records. For a variety of reasons, including changing definitions of TRU wastes, differing objectives for the estimates, and poor historical data, the published results have sometimes been in conflict. The purpose of this review was (1) to attempt to explain both the rationale for and differences among the various estimates, and (2) to update the estimates based on more recent information obtained from waste characterization and from evaluations of ORNL waste data bases and historical records. The latter included information obtained from an expert panel's review and reconciliation of inconsistencies in data identified during preparation of the ORNL input for the third revision of the Baseline Inventory Report for the Waste Isolation Pilot Plant. The results summarize current understanding of the relationship between past estimates of buried TRU wastes and provide the most up-to-date information on recorded burials thereafter. The limitations of available information on the latter and thus the need for improved waste characterization are highlighted

  3. Distributionally Robust Return-Risk Optimization Models and Their Applications

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Based on the risk control of conditional value-at-risk, distributionally robust return-risk optimization models with box constraints of random vector are proposed. They describe uncertainty in both the distribution form and moments (mean and covariance matrix of random vector. It is difficult to solve them directly. Using the conic duality theory and the minimax theorem, the models are reformulated as semidefinite programming problems, which can be solved by interior point algorithms in polynomial time. An important theoretical basis is therefore provided for applications of the models. Moreover, an application of the models to a practical example of portfolio selection is considered, and the example is evaluated using a historical data set of four stocks. Numerical results show that proposed methods are robust and the investment strategy is safe.

  4. Application of a procedure oriented crew model to modelling nuclear plant operation

    International Nuclear Information System (INIS)

    Baron, S.

    1986-01-01

    PROCRU (PROCEDURE-ORIENTED CREW MODEL) is a model developed to analyze flight crew procedures in a commercial ILS approach-to-landing. The model builds on earlier, validated control-theoretic models for human estimation and control behavior, but incorporates features appropriate to analyzing supervisory control in multi-task environments. In this paper, the basic ideas underlying the PROCRU model, and the generalization of these ideas to provide a supervisory control model of wider applicability are discussed. The potential application of this supervisory control model to nuclear power plant operations is considered. The range of problems that can be addressed, the kinds of data that will be needed and the nature of the results that might be expected from such an application are indicated

    The value of systems science modelling methods in the health sector is increasingly being recognised. Of particular promise is the potential of these methods to improve operational aspects of healthcare capacity and delivery, analyse policy options for health system reform and guide investments to address complex public health problems. Because it lends itself to a participatory approach, system dynamics modelling has been a particularly appealing method that aims to align stakeholder understanding of the underlying causes of a problem and achieve consensus for action. The aim of this review is to determine the effectiveness of system dynamics modelling for health policy, and explore the range and nature of its application. A systematic search was conducted to identify articles published up to April 2015 from the PubMed, Web of Knowledge, Embase, ScienceDirect and Google Scholar databases. The grey literature was also searched. Papers eligible for inclusion were those that described applications of system dynamics modelling to support health policy at any level of government. Six papers were identified, comprising eight case studies of the application of system dynamics modelling to support health policy. No analytic studies were found that examined the effectiveness of this type of modelling. Only three examples engaged multidisciplinary stakeholders in collective model building. Stakeholder participation in model building reportedly facilitated development of a common 'mental map' of the health problem, resulting in consensus about optimal policy strategy and garnering support for collaborative action. The paucity of relevant papers indicates that, although the volume of descriptive literature advocating the value of system dynamics modelling is considerable, its practical application to inform health policy making is yet to be routinely applied and rigorously evaluated. Advances in software are allowing the participatory model building approach to be extended to

    2014-01-01

    Streams and rivers host a significant portion of Earth's biodiversity and provide important ecosystem services for human populations. Accurate information regarding the status and trends of stream resources is vital for their effective conservation and management. Most statistical techniques applied to data measured on stream networks were developed for terrestrial applications and are not optimized for streams. A new class of spatial statistical model, based on valid covariance structures for stream networks, can be used with many common types of stream data (e.g., water quality attributes, habitat conditions, biological surveys) through application of appropriate distributions (e.g., Gaussian, binomial, Poisson). The spatial statistical network models account for spatial autocorrelation (i.e., nonindependence) among measurements, which allows their application to databases with clustered measurement locations. Large amounts of stream data exist in many areas where spatial statistical analyses could be used to develop novel insights, improve predictions at unsampled sites, and aid in the design of efficient monitoring strategies at relatively low cost. We review the topic of spatial autocorrelation and its effects on statistical inference, demonstrate the use of spatial statistics with stream datasets relevant to common research and management questions, and discuss additional applications and development potential for spatial statistics on stream networks. Free software for implementing the spatial statistical network models has been developed that enables custom applications with many stream databases.

  7. Nonlinear Mathematical Modeling in Pneumatic Servo Position Applications

    Antonio Carlos Valdiero

    2011-01-01

    Full Text Available This paper addresses a new methodology for servo pneumatic actuators mathematical modeling and selection from the dynamic behavior study in engineering applications. The pneumatic actuator is very common in industrial application because it has the following advantages: its maintenance is easy and simple, with relatively low cost, self-cooling properties, good power density (power/dimension rate, fast acting with high accelerations, and installation flexibility. The proposed fifth-order nonlinear mathematical model represents the main characteristics of this nonlinear dynamic system, as servo valve dead zone, air flow-pressure relationship through valve orifice, air compressibility, and friction effects between contact surfaces in actuator seals. Simulation results show the dynamic performance for different pneumatic cylinders in order to see which features contribute to a better behavior of the system. The knowledge of this behavior allows an appropriate choice of pneumatic actuator, mainly contributing to the success of their precise control in several applications.

  7. A framework for development and application of hydrological models

    Directory of Open Access Journals (Sweden)

    T. Wagener

    2001-01-01

    Full Text Available Many existing hydrological modelling procedures do not make best use of available information, resulting in non-minimal uncertainties in model structure and parameters, and a lack of detailed information regarding model behaviour. A framework is required that balances the level of model complexity supported by the available data with the level of performance suitable for the desired application. Tools are needed that make optimal use of the information available in the data to identify model structure and parameters, and that allow a detailed analysis of model behaviour. This should result in appropriate levels of model complexity as a function of available data, hydrological system characteristics and modelling purpose. This paper introduces an analytical framework to achieve this, and tools to use within it, based on a multi-objective approach to model calibration and analysis. The utility of the framework is demonstrated with an example from the field of rainfall-runoff modelling. Keywords: hydrological modelling, multi-objective calibration, model complexity, parameter identifiability

    Champendal, Alexandre; Kanevski, Mikhail; Huguenot, Pierre-Emmanuel

    2014-05-01

    The problem of air pollution modelling in urban zones is of great importance both from scientific and applied points of view. At present there are several fundamental approaches either based on science-based modelling (air pollution dispersion) or on the application of space-time geostatistical methods (e.g. family of kriging models or conditional stochastic simulations). Recently, there were important developments in so-called Land Use Regression (LUR) models. These models take into account geospatial information (e.g. traffic network, sources of pollution, average traffic, population census, land use, etc.) at different scales, for example, using buffering operations. Usually the dimension of the input space (number of independent variables) is within the range of (10-100). It was shown that LUR models have some potential to model complex and highly variable patterns of air pollution in urban zones. Most of LUR models currently used are linear models. In the present research the nonlinear LUR models are developed and applied for Geneva city. Mainly two nonlinear data-driven models were elaborated: multilayer perceptron and random forest. An important part of the research deals also with a comprehensive exploratory data analysis using statistical, geostatistical and time series tools. Unsupervised self-organizing maps were applied to better understand space-time patterns of the pollution. The real data case study deals with spatial-temporal air pollution data of Geneva (2002-2011). Nitrogen dioxide (NO2) has caught our attention. It has effects on human health and on plants; NO2 contributes to the phenomenon of acid rain. The negative effects of nitrogen dioxides on plants are the reduction of the growth, production and pesticide resistance. And finally, the effects on materials: nitrogen dioxide increases the corrosion. The data used for this study consist of a set of 106 NO2 passive sensors. 80 were used to build the models and the remaining 36 have constituted

    This paper describes a modeling approach to analyze light water reactor component degradation and failure data to understand the aging process of components. As used here, degradation modeling is the analysis of information on component degradation in order to develop models of the process and its implications. This particular modeling focuses on the analysis of the times of component degradations, to model how the rate of degradation changes with the age of the component. The methodology presented also discusses the effectiveness of maintenance as applicable to aging evaluations. The specific applications which are performed show quantitative models of component degradation rates and component failure rates from plant-specific data. The statistical techniques which are developed and applied allow aging trends to be effectively identified in the degradation data, and in the failure data. Initial estimates of the effectiveness of maintenance in limiting degradations from becoming failures also are developed. These results are important first steps in degradation modeling, and show that degradation can be modeled to identify aging trends

    2014-12-01

    Full Text Available The paper presents functional modelling and its application for diagnosis in nuclear power plants. Functional modelling is defined and its relevance for coping with the complexity of diagnosis in large scale systems like nuclear plants is explained. The diagnosis task is analyzed and it is demonstrated that the levels of abstraction in models for diagnosis must reflect plant knowledge about goals and functions which is represented in functional modelling. Multilevel flow modelling (MFM, which is a method for functional modelling, is introduced briefly and illustrated with a cooling system example. The use of MFM for reasoning about causes and consequences is explained in detail and demonstrated using the reasoning tool, the MFMSuite. MFM applications in nuclear power systems are described by two examples: a PWR; and an FBR reactor. The PWR example show how MFM can be used to model and reason about operating modes. The FBR example illustrates how the modelling development effort can be managed by proper strategies including decomposition and reuse.

  18. Statistical modelling for recurrent events: an application to sports injuries.

    Science.gov (United States)

    Ullah, Shahid; Gabbett, Tim J; Finch, Caroline F

    2014-09-01

    Injuries are often recurrent, with subsequent injuries influenced by previous occurrences and hence correlation between events needs to be taken into account when analysing such data. This paper compares five different survival models (Cox proportional hazards (CoxPH) model and the following generalisations to recurrent event data: Andersen-Gill (A-G), frailty, Wei-Lin-Weissfeld total time (WLW-TT) marginal, Prentice-Williams-Peterson gap time (PWP-GT) conditional models) for the analysis of recurrent injury data. Empirical evaluation and comparison of different models were performed using model selection criteria and goodness-of-fit statistics. Simulation studies assessed the size and power of each model fit. The modelling approach is demonstrated through direct application to Australian National Rugby League recurrent injury data collected over the 2008 playing season. Of the 35 players analysed, 14 (40%) players had more than 1 injury and 47 contact injuries were sustained over 29 matches. The CoxPH model provided the poorest fit to the recurrent sports injury data. The fit was improved with the A-G and frailty models, compared to WLW-TT and PWP-GT models. Despite little difference in model fit between the A-G and frailty models, in the interest of fewer statistical assumptions it is recommended that, where relevant, future studies involving modelling of recurrent sports injury data use the frailty model in preference to the CoxPH model or its other generalisations. The paper provides a rationale for future statistical modelling approaches for recurrent sports injury. Published by the BMJ Publishing Group Limited.

  1. Semantic Information Modeling for Emerging Applications in Smart Grid

    Energy Technology Data Exchange (ETDEWEB)

    Zhou, Qunzhi; Natarajan, Sreedhar; Simmhan, Yogesh; Prasanna, Viktor

    2012-04-16

    Smart Grid modernizes power grid by integrating digital and information technologies. Millions of smart meters, intelligent appliances and communication infrastructures are under deployment allowing advanced IT applications to be developed to secure and manage power grid operations. Demand response (DR) is one such emerging application to optimize electricity demand by curtailing/shifting power load when peak load occurs. Existing DR approaches are mostly based on static plans such as pricing policies and load shedding schedules. However, improvements to power management applications rely on data emanating from existing and new information sources with the growth of Smart Grid information space. In particular, dynamic DR algorithms depend on information from smart meters that report interval-based power consumption measurement, HVAC systems that monitor buildings heat and humidity, and even weather forecast services. In order for emerging Smart Grid applications to take advantage of the diverse data influx, extensible information integration is required. In this paper, we develop an integrated Smart Grid information model using Semantic Web techniques and present case studies of using semantic information for dynamic DR. We show the semantic model facilitates information integration and knowledge representation for developing the next generation Smart Grid applications.

  2. Challenges of Microgrids in Remote Communities: A STEEP Model Application

    Directory of Open Access Journals (Sweden)

    Daniel Akinyele

    2018-02-01

    Full Text Available There is a growing interest in the application of microgrids around the world because of their potential for achieving a flexible, reliable, efficient and smart electrical grid system and supplying energy to off-grid communities, including their economic benefits. Several research studies have examined the application issues of microgrids. However, a lack of in-depth considerations for the enabling planning conditions has been identified as a major reason why microgrids fail in several off-grid communities. This development requires research efforts that consider better strategies and framework for sustainable microgrids in remote communities. This paper first presents a comprehensive review of microgrid technologies and their applications. It then proposes the STEEP model to examine critically the failure factors based on the social, technical, economic, environmental and policy (STEEP perspectives. The model details the key dimensions and actions necessary for addressing the challenge of microgrid failure in remote communities. The study uses remote communities within Nigeria, West Africa, as case studies and demonstrates the need for the STEEP approach for better understanding of microgrid planning and development. Better insights into microgrid systems are expected to address the drawbacks and improve the situation that can lead to widespread and sustainable applications in off-grid communities around the world in the future. The paper introduces the sustainable planning framework (SPF based on the STEEP model, which can form a general basis for planning microgrids in any remote location.

    2013-03-01

    In this paper, we present a model for application distribution and related security attacks in dense vehicular ad hoc networks (VANET) and sparse VANET which forms a delay tolerant network (DTN). We study the vulnerabilities of VANET to evaluate the attack scenarios and introduce a new attacker`s model as an extension to the work done in [6]. Then a VANET model has been proposed that supports the application distribution through proxy app stores on top of mobile platforms installed in vehicles. The steps of application distribution have been studied in detail. We have identified key attacks (e.g. malware, spamming and phishing, software attack and threat to location privacy) for dense VANET and two attack scenarios for sparse VANET. It has been shown that attacks can be launched by distributing malicious applications and injecting malicious codes to On Board Unit (OBU) by exploiting OBU software security holes. Consequences of such security attacks have been described. Finally, countermeasures including the concepts of sandbox have also been presented in depth.

    2016-01-01

    Given the persistent recurrence of armed conflict, influential actors owe it to the affected communities to take action. The legitimacy of health professionals to mitigate the effects of conflict relates to their ability to save lives and address the physical and mental consequences of armed conflict during which thousands of lives may be lost. Medical professionals have unique and potentially far-reaching skills. These become crucial during wartime and disasters in terms of providing medical services and humanitarian aid. However, they are insufficiently used in one area: involvement in politics as a tool to foster peace. Despite this, Sudanese individuals from medical backgrounds have participated actively in conflict resolution and peace-building processes. In fact, their political actions throughout the last six decades have aimed to prevent conflict at four different levels, which are described by Yusuf et al. in their article on the political involvement of health professionals in prevention. Their stand against President Nimeiri's Sharia laws was primordial prevention of religious conflict at the national level. Their leading role in the second Sudanese Intifada uprising was a key factor in saving the country from civil war, and another example of primary prevention. Sudanese physicians were also involved in secondary prevention by being influentially involved in almost all national peace agreements. Avoiding disputes at the tertiary level represents the weakest link in their repeated efforts. This paper outlines the different roles Sudanese medical personnel have taken in peacemaking. It also critically evaluates them in order to consider new methods of political involvement that suit future challenges.

    Online computer models of first order beam optics have been developed for the commissioning, control and operation of the entire SLC including Damping Rings, Linac, Positron Return Line and Collider Arcs. A generalized online environment utilizing these models provides the capability for interactive selection of a desire optics configuration and for the study of its properties. Automated procedures have been developed which calculate and load beamline component set-points and which can scale magnet strengths to achieve desired beam properties for any Linac energy profile. Graphic displays facilitate comparison of design, desired and actual optical characteristics of the beamlines. Measured beam properties, such as beam emittance and dispersion, can be incorporated interactively into the models and used for beam matching and optimization of injection and extraction efficiencies and beam transmissions. The online optics modeling facility also serves as the foundation for many model-driven applications such as autosteering, calculation of beam launch parameters, emittance measurement and dispersion correction

    Full Text Available Forest ecosystem dynamics are driven by a complex array of simultaneous cause-and-effect relationships. Understanding this complex web requires specialized analytical techniques such as Structural Equation Modeling (SEM. The SEM framework and implementation steps are outlined in this study, and we then demonstrate the technique by application to overstory-understory relationships in mature Douglas-fir forests in the northwestern USA. A SEM model was formulated with (1 a path model representing the effects of successively higher layers of vegetation on late-seral herbs through processes such as light attenuation and (2 a measurement model accounting for measurement errors. The fitted SEM model suggested a direct negative effect of light attenuation on late-seral herbs cover but a direct positive effect of northern aspect. Moreover, many processes have indirect effects mediated through midstory vegetation. SEM is recommended as a forest management tool for designing silvicultural treatments and systems for attaining complex arrays of management objectives.

  11. Modelling of transport processes in porous media for energy applications

    Energy Technology Data Exchange (ETDEWEB)

    Kangas, M.

    1996-12-31

    Flows in porous media are encountered in many branches of technology. In these phenomena, a fluid of some sort is flowing through porous matrix of a solid medium. Examples of the fluid are water, air, gas and oil. The solid matrix can be soil, fissured rock, ceramics, filter paper, etc. The flow is in many cases accompanied by transfer of heat or solute within the fluid or between the fluid and the surrounding solid matrix. Chemical reactions or microbiological processes may also be taking place in the system. In this thesis, a 3-dimensional computer simulation model THETA for the coupled transport of fluid, heat, and solute in porous media has been developed and applied to various problems in the field of energy research. Although also applicable to porous medium applications in general, the version of the model described and used in this work is intended for studying the transport processes in aquifers, which are geological formations containing groundwater. The model highlights include versatile input and output routines, as well as modularity which, for example, enables an easy adaptation of the model for use as a subroutine in large energy system simulations. Special attention in the model development has been attached to high flow conditions, which may be present in Nordic esker aquifers located close to the ground surface. The simulation model has been written with FORTRAN 77 programming language, enabling a seamless operation both in PC and main frame environments. For PC simulation, a special graphic user interface has been developed. The model has been used with success in a wide variety of applications, ranging from basic thermal analyses to thermal energy storage system evaluations and nuclear waste disposal simulations. The studies have shown that thermal energy storage is feasible also in Nordic high flow aquifers, although at the cost of lower recovery temperature level, usually necessitating the use of heat pumps. In the nuclear waste studies, it

The model provides a unified multiresolution representation of the spectral and temporal features of sound likely critical in the perception of timbre. Several types of complex stimuli are used to demonstrate the spectrotemporal information preserved by the model. Shown by these examples, this two stage model reflects the apparent progressive loss of temporal dynamics along the auditory pathway from the rapid phase-locking (several kHz in auditory nerve), to moderate rates of synchrony (several hundred Hz in midbrain), to much lower rates of modulations in the cortex (around 30 Hz). To complete this model, several projection-based reconstruction algorithms are implemented to resynthesize the sound from the representations with reduced dynamics. One particular application of this model is to assess speech intelligibility. The spectro-temporal Modulation Transfer Functions (MTF) of this model is investigated and shown to be consistent with the salient trends in the human MTFs (derived from human detection thresholds) which exhibit a lowpass function with respect to both spectral and temporal dimensions, with 50% bandwidths of about 16 Hz and 2 cycles/octave. Therefore, the model is used to demonstrate the potential relevance of these MTFs to the assessment of speech intelligibility in noise and reverberant conditions. Another useful feature is the phase singularity emerged in the scale space generated by this multiscale auditory model. The singularity is shown to have certain robust properties and carry the crucial information about the spectral profile. Such claim is justified by perceptually tolerable resynthesized sounds from the nonconvex singularity set. In addition, the singularity set is demonstrated to encode the pitch and formants at different scales. These properties make the singularity set very suitable for traditional

  13. Overview on available animal models for application in leukemia research

    The term ''leukemia'' encompasses a group of diseases with a variable clinical and pathological presentation. Its cellular origin, its biology and the underlying molecular genetic alterations determine the very variable and individual disease phenotype. The focus of this review is to discuss the most important guidelines to be taken into account when we aim at developing an ''ideal'' animal model to study leukemia. The animal model should mimic all the clinical, histological and molecular genetic characteristics of the human phenotype and should be applicable as a clinically predictive model. It should achieve all the requirements to be used as a standardized model adaptive to basic research as well as to pharmaceutical practice. Furthermore it should fulfill all the criteria to investigate environmental risk factors, the role of genomic mutations and be applicable for therapeutic testing. These constraints limit the usefulness of some existing animal models, which are however very valuable for basic research. Hence in this review we will primarily focus on genetically engineered mouse models (GEMMs) to study the most frequent types of childhood leukemia. GEMMs are robust models with relatively low site specific variability and which can, with the help of the latest gene modulating tools be adapted to individual clinical and research questions. Moreover they offer the possibility to restrict oncogene expression to a defined target population and regulate its expression level as well as its timely activity. Until recently it was only possible in individual cases to develop a murin model, which fulfills the above mentioned requirements. Hence the development of new regulatory elements to control targeted oncogene expression should be priority. Tightly controlled and cell specific oncogene expression can then be combined with a knock-in approach and will depict a robust murine model, which enables almost physiologic oncogene

    In this paper, we describe a combination of algorithms for high-fidelity geometric modeling and mesh generation. Although our methods and implementations are application-neutral, our primary target application is multiscale biomedical models that range in scales across the molecular, cellular, and organ levels. Our software toolchain implementing these algorithms is general in the sense that it can take as input a molecule in PDB/PQR forms, a 3D scalar volume, or a user-defined triangular surface mesh that may have very low quality. The main goal of our work presented is to generate high quality and smooth surface triangulations from the aforementioned inputs, and to reduce the mesh sizes by mesh coarsening. Tetrahedral meshes are also generated for finite element analysis in biomedical applications. Experiments on a number of bio-structures are demonstrated, showing that our approach possesses several desirable properties: feature-preservation, local adaptivity, high quality, and smoothness (for surface meshes). Finally, the availability of this software toolchain will give researchers in computational biomedicine and other modeling areas access to higher-fidelity geometric models.

  15. Risk Measurement and Risk Modelling Using Applications of Vine Copulas

    2017-09-01

    Full Text Available This paper features an application of Regular Vine copulas which are a novel and recently developed statistical and mathematical tool which can be applied in the assessment of composite financial risk. Copula-based dependence modelling is a popular tool in financial applications, but is usually applied to pairs of securities. By contrast, Vine copulas provide greater flexibility and permit the modelling of complex dependency patterns using the rich variety of bivariate copulas which may be arranged and analysed in a tree structure to explore multiple dependencies. The paper features the use of Regular Vine copulas in an analysis of the co-dependencies of 10 major European Stock Markets, as represented by individual market indices and the composite STOXX 50 index. The sample runs from 2005 to the end of 2013 to permit an exploration of how correlations change indifferent economic circumstances using three different sample periods: pre-GFC (January 2005–July 2007, GFC (July 2007– September 2009, and post-GFC periods (September 2009–December 2013. The empirical results suggest that the dependencies change in a complex manner, and are subject to change in different economic circumstances. One of the attractions of this approach to risk modelling is the flexibility in the choice of distributions used to model co-dependencies. The practical application of Regular Vine metrics is demonstrated via an example of the calculation of the VaR of a portfolio made up of the indices.

    Full Text Available The post-Mabo era was to be the age of reconciliation and the end of unjust dispossession of indigenous peoples’ lands. However, as the more recent cases in native title show this vision did not become the reality. In this paper, I will examine Mabo in its historical context. In particular I will examine the claim that Mabo was a product of the “new history” movement in Australia. This movement developed in response to the silence that had shrouded the history of colonial relations between indigenous and non-indigenous peoples for most of the 19th and 20th centuries. Through the writing of these histories, new historians have raised awareness of the history of colonization in Australia and the impact it has had on indigenous peoples in particular. In the paper I will outline the ways in which Mabo is a product of this history. However, if Mabo did not bring to an end to the injustice and inequality facing indigenous peoples in the context of land law in Australia, it is because of the traces of another history informing that decision and the events that followed it. In this paper I will refer to this history as the “old history” of Australia. In this history indigenous peoples are placed in a paradoxical position: they are inferior, but still seen as threat to the colonial enterprise. The paper will explore how this “history” is repeated in Mabo and continues to inform the High Court’s approach to native title law.

  17. A pharmacy-based medication reconciliation and review program in hemodialysis patients: a prospective study

    2016-09-01

    Full Text Available Background: Hemodialysis (HD patients are on multiple medications, see many prescribers and have many hospitalizations which put them at risk for medication record discrepancies and medication related problems (MRP. Being able to effectively identify and reconcile these medication issues is crucial in reducing hospitalizations, morbidities, and mortalities. The care of the hemodialysis patients can be enhanced by incorporating a pharmacist into the interprofessional team. There is little data in the literature on medication record discrepancies and MRP’s in dialysis patients. Objective: The objectives of this research were to determine the types of medication discrepancies and MRPs in dialysis patients and if recommendations for changes based on these findings were accepted by providers. Methods: Patients were asked to bring medications to the dialysis unit for review. Discrepancy and MRP recommendations were communicated to the unit staff via written progress notes. A follow-up was performed an average of 33 days later to determine if the recommendations were accepted. Results: Overall, in 93 unique patients, 376 discrepancies (3.1 per patient and 64 MRPs (0.5 per patient were identified. The most common type of discrepancy and MRP was drug omission and indication without drug, respectively. Of the total 440 interventions, 77% were ultimately accepted. Discrepancies were more likely to be accepted as compared to MRPs (85% vs. 27%, respectively. Conclusion: Medication record discrepancies and MRPs are common in dialysis patients. Recommendations related to discrepancies were more likely to be accepted by the providers as compared to MRPs. Medication records became inaccurate within 12 months. A pharmacy-based medication reconciliation and review program may have an important impact on the care of hemodialysis patients.

  18. Medical identity theft: prevention and reconciliation initiatives at Massachusetts General Hospital.

    Medical identity theft refers to the misuse of another individual's identifying medical information to receive medical care. Beyond the financial burden on patients, hospitals, health insurance companies, and government insurance programs, undetected cases pose major patient safety challenges. Inaccuracies in the medical record may persist even after the theft has been identified because of restrictions imposed by patient privacy laws. Massachusetts General Hospital (MGH; Boston) has conducted initiatives to prevent medical identity theft and to better identify and respond to cases when they occur. Since 2007, MGH has used a notification tree to standardize reporting of red flag incidents (warning signs of identity theft, such as suspicious personal identifiers or account activity). A Data Integrity Dashboard allows for tracking and reviewing of all potential incidents of medical identity theft to detect trends and targets for mitigation. An identity-checking policy, VERI-(Verify Everyone's Identity) Safe Patient Care, requires photo identification at every visit and follow-up if it is not provided. Data from MGH suggest that an estimated 120 duplicate medical records are created each month, 25 patient encounters are likely tied to identity theft or fraud each quarter, and 14 patients are treated under the wrong medical record number each year. As of December 2013, 80%-85% of patients were showing photo identification at appointments. Although an organization's policy changes and educational campaigns can improve detection and reconciliation of medical identity theft cases, national policies should be implemented to streamline the process of correcting errors in medical records, reduce the financial disincentive for hospitals to detect and report cases, and create a single point of entry to reduce the burden on individuals and providers to reconcile cases.

    Medication reconciliation (MedRec) has been a mandated or recommended activity in Canada, the USA and the UK for nearly 10 years. Accreditation bodies in North America will soon require MedRec for every admission, transfer and discharge of every patient. Studies of MedRec have revealed unintentional discrepancies in prescriptions but no clear evidence that clinically important outcomes are improved, leading to widely variable practices. Our objective was to apply process mapping methodology to MedRec to clarify current processes and resource usage, identify potential efficiencies and gaps in care, and make recommendations for improvement in the light of current literature evidence of effectiveness. Process engineers observed and recorded all MedRec activities at 3 academic teaching hospitals, from initial emergency department triage to patient discharge, for general internal medicine patients. Process maps were validated with frontline staff, then with the study team, managers and patient safety leads to summarise current problems and discuss solutions. Across all of the 3 hospitals, 5 general problem themes were identified: lack of use of all available medication sources, duplication of effort creating inefficiency, lack of timeliness of completion of the Best Possible Medication History, lack of standardisation of the MedRec process, and suboptimal communication of MedRec issues between physicians, pharmacists and nurses. MedRec as practised in this environment requires improvements in quality, timeliness, consistency and dissemination. Further research exploring efficient use of resources, in terms of personnel and costs, is required. Published by the BMJ Publishing Group Limited.

  20. Conflict and governability in Northern Uganda: Possibilities and limits of mato oput reconciliation rituals

    Directory of Open Access Journals (Sweden)

    José Carlos Rodríguez Soto

    2009-10-01

    Full Text Available The war that broke out in Northern Uganda in 1986 – one of the most forgotten wars of our times – was the result of a long North-South conflict in the country, and has caused the displacement of 2 million people, the deaths of some 100,000 citizens and the kidnapping of 40,000 children by the Lord’s Resistance Army (LRA guerrilla. Repeated attempts by civil society (particularly by religious and traditional leaders to stop the conflict through negotiation has ended, time after time, in failures that have led to new waves of violence, most of them directed against the civil population. In this context, the traditional culture of the Acholi people has played a paramount role, and has backed several reconciliation initiatives. The most successful one was the amnesty law which, since 2002, has succeeded in reincorporating more than 12,000 people from the LRA. However, the use of traditional peace processes, particularly the mato oput, clashes with a reality that is unduly complicated by the thousands of murders that have been committed, sometimes by minors who have been forced to kill. The intervention of the International Criminal Court in The Hague since 2004 has not produced a very favourable response among the Acholi society, which views this court more as an obstacle than as a means to help bring this tragedy to an end. The dilemmas created by conflicts of interest between peace and justice, and the attempts to strengthen the role of traditional leaders to reincorporate combatants returning from war into society are just some of the underlying issues in this conflict which has, furthermore, an international dimension, as it has now affected four African countries.

    Transition of patients care between settings presents an increased opportunity for errors and preventable morbidity. A number of studies outlined that pharmacy-led medicine reconciliation (MR) might facilitate safer information transfer and medication use. MR practice is not well standardized and often delivered in combination with other health care activities. The question regarding the effects and costs of pharmacy-led MR and the optimum MR practice is warranted of value. To review the evidence for the effects and costs/cost-effectiveness of complete pharmacy-led MR in hospital settings. A systematic review searching the following database was conducted up to the 13th December 2015; EMBASE & MEDLINE Ovid, CINAHL and the Cochrane library. Studies evaluating pharmacy-led MR performed fully from admission till discharges were included. Studies evaluated non-pharmacy-led MR at only one end of patient care or transfer was not included. Articles were screened and extracted independently by two investigators. Studies were divided into those in which: MR was the primary element of the intervention and labeled as "primarily MR" studies, or MR combined with non-MR care activities and labeled as "supplemented MR" studies. Quality assessment of studies was performed by independent reviewers using a pre-defined and validated tool. The literature search identified 4065 citations, of which 13 implemented complete MR. The lack of evidence precluded addressing the effects and costs of MR. The composite of optimum MR practice is not widely standardized and requires discussion among health professions and key organizations. Research focused on evaluating cost-effectiveness of pharmacy-led MR is lacking. Copyright © 2016 Elsevier Inc. All rights reserved.

    - Ndali - Che Kamati

    2014-12-01

    Full Text Available The concept of national reconciliation became policy strategies in political discourse in Zimbabwe and Namibia after independence and South Africa after democratisation. The objective was to avoid the civil war experienced in neighbouring Angola and Mozambique after independence. Current argument however is that reconciliation mainly harmonising relations between blacks and whites and between the new government and capital is not sufficient. It is argued that reconciliation should fundamentally extent to the formerly deprived black majority the right of access to natural resource and addresses their economic well being. Political processes and developments in these three countries also reveal that settlement compromises made at independence and new democratic dispensation predicated on liberal constitutions followed by neo-liberal economic policies are sources of enormous governance challenges facing the leadership of these countries today.

  5. A review of toxicity models for realistic atmospheric applications

    2014-02-01

    There are many applications that need to study human health effects caused by exposure to toxic chemicals. Risk analysis for industrial sites, study of population health impacts of atmospheric pollutants, and operations research for assessing the potential impacts of chemical releases in military contexts are some examples. Because of safety risks and the high cost of field trials involving hazardous chemical releases, computer simulations are widely used for such studies. Modelling of atmospheric transport and dispersion of chemicals released into the atmosphere to determine the toxic chemical concentrations to which individuals will be exposed is one main component of these simulations, and there are well established atmospheric dispersion models for this purpose. Estimating the human health effects caused by the exposure to these predicted toxic chemical concentrations is the other main component. A number of different toxicity models for assessing the health effects of toxic chemical exposure are found in the literature. Because these different models have been developed based on different assumptions about the plume characteristics, chemical properties, and physiological response, there is a need to review and compare these models to understand their applicability. This paper reviews several toxicity models described in the literature. The paper also presents results of applying different toxicity models to simulated concentration time series data. These results show that the use of ensemble mean concentrations, which are what atmospheric dispersion models typically provide, to estimate human health effects of exposure to hazardous chemical releases may underestimate their impact when toxic exponent, n, of the chemical is greater than one; the opposite phenomenon appears to hold when n biological recovery processes may predict greater toxicity than the explicitly parameterised models. Despite the wide variety of models of varying degrees of complexity that is

    We address the nonparametric model validation problem for hidden Markov models with partially observable variables and hidden states. We achieve this goal by constructing a nonparametric simultaneous confidence envelope for transition density function of the observable variables and checking whether the parametric density estimate is contained within such an envelope. Our specification test procedure is motivated by a functional connection between the transition density of the observable variables and the Markov transition kernel of the hidden states. Our approach is applicable for continuous time diffusion models, stochastic volatility models, nonlinear time series models, and models with market microstructure noise.

    Prevention of consuming contaminated food with toxic microorganisms causing infections and consideration of food protection and new microbial inactivation methods are obligatory situations. Food microbiology is mainly related with unwanted microorganisms spoiling foods during processing and transporting stages and causing diseases. Determination of pathogen microorganisms is important for human health to define and prevent dangers and elongate shelf life. Inactivation of pathogen microorganisms can provide food security and reduce nutrient losses. Microbial inactivation which is using methods of food protection such as food safety and fresh. With this aim, various methods are used such as classical thermal processes (pasteurisation, sterilisation), pressured electrical field (PEF), ionised radiation, high pressure, ultrasonic waves and plasma sterilisation. Microbial inactivation modelling is a secure and effective method in food production. A new microbiological application can give useful results for risk assessment in food, inactivation of microorganisms and improvement of shelf life. Application and control methods should be developed and supported by scientific research and industrial applications

    2017-12-01

    In an effort to study the environmental (emissions, soil quality) and production (yield) impacts of biochar application at regional scales we coupled the APSIM-Biochar model with the pSIMS parallel platform. So far the majority of biochar research has been concentrated on lab to field studies to advance scientific knowledge. Regional scale assessments are highly needed to assist decision making. The overall objective of this simulation study was to identify areas in the USA that have the most gain environmentally from biochar's application, as well as areas which our model predicts a notable yield increase due to the addition of biochar. We present the modifications in both APSIM biochar and pSIMS components that were necessary to facilitate these large scale model runs across several regions in the United States at a resolution of 5 arcminutes. This study uses the AgMERRA global climate data set (1980-2010) and the Global Soil Dataset for Earth Systems modeling as a basis for creating its simulations, as well as local management operations for maize and soybean cropping systems and different biochar application rates. The regional scale simulation analysis is in progress. Preliminary results showed that the model predicts that high quality soils (particularly those common to Iowa cropping systems) do not receive much, if any, production benefit from biochar. However, soils with low soil organic matter ( 0.5%) do get a noteworthy yield increase of around 5-10% in the best cases. We also found N2O emissions to be spatial and temporal specific; increase in some areas and decrease in some other areas due to biochar application. In contrast, we found increases in soil organic carbon and plant available water in all soils (top 30 cm) due to biochar application. The magnitude of these increases (% change from the control) were larger in soil with low organic matter (below 1.5%) and smaller in soils with high organic matter (above 3%) and also dependent on biochar

    2017-05-01

    Little is known about the teaching and learning implications of instructional storytelling (IST) in nursing education or its potential connection to nursing theory. The literature establishes storytelling as a powerful teaching-learning method in the educational, business, humanities, and health sectors, but little exploration exists that is specific to nursing. An example of a story demonstrating application of the domains of Tanner's clinical judgment model links storytelling with learning outcomes appropriate for the novice nursing student. Application of Tanner's clinical judgment model offers consistency of learning experience while preserving the creativity inherent in IST. Further research into student learning outcomes achievement using IST is warranted as a step toward establishing best practices with IST in nursing education. [J Nurs Educ. 2017;56(5):305-308.].

    Although art therapists have discussed the importance of taking a positive stance in terms of ethical decision making (Hinz, 2011), an ethical decision-making model applicable for the field of art therapy has yet to emerge. As the field of art therapy continues to grow, an accessible, theoretically grounded, and logical decision-making model is…

    This book provides a modern introductory tutorial on specialized methodological and applied aspects of spatial and temporal modeling. The areas covered involve a range of topics which reflect the diversity of this domain of research across a number of quantitative disciplines. For instance, the first chapter deals with non-parametric Bayesian inference via a recently developed framework known as kernel mean embedding which has had a significant influence in machine learning disciplines. The second chapter takes up non-parametric statistical methods for spatial field reconstruction and exceedance probability estimation based on Gaussian process-based models in the context of wireless sensor network data. The third chapter presents signal-processing methods applied to acoustic mood analysis based on music signal analysis. The fourth chapter covers models that are applicable to time series modeling in the domain of speech and language processing. This includes aspects of factor analysis, independent component an...

    The IT industry tries to employ a number of models to identify the defects in the construction of software projects. In this paper, we present COQUALMO and its limitations and aim to increase the quality without increasing the cost and time. The computation time, cost, and effort to predict the residual defects are very high; this was overcome by developing an appropriate new quality model named the software testing defect corrective model (STDCM). The STDCM was used to estimate the number of remaining residual defects in the software product; a few assumptions and the detailed steps of the STDCM are highlighted. The application of the STDCM is explored in software projects. The implementation of the model is validated using statistical inference, which shows there is a significant improvement in the quality of the software projects.
