    Yang, Lili; Wang, Yiming; Dong, Qiaoxue

    Quantification of tomato's fruit-sets depends on the level of competition for assimilate in different environment, and this paper presented some results of fruit yield and quality (fruit size) in response to environment (mainly respect to and planting-density and light). Some experiments had been carried out to find the relationship between growth rules of tomato and plant densities A structural-functional model GREENLAB has been developed to simulate it. The results show that increasing plant density results in an increment of biomass production on a ground area but in a reduction of single plant fresh weight. To find rules between organ sink and source relationship, calibrations Environmental conditions were introduced into the model checking the influence on Q/D over plant growth period and fruit set ratio. It is found that changing the Q/D ratio in some critical periods can be used to optimize fruit set and yield of greenhouse tomato.

    • Background and Aims There are three reasons for the increasing demand for crop models that build the plant on the basis of architectural principles and organogenetic processes: (1) realistic concepts for developing new crops need to be guided by such models; (2) there is an increasing interest in crop phenotypic plasticity, based on variable architecture and morphology; and (3) engineering of mechanized cropping systems requires information on crop architecture. The functional–structural model GREENLAB was recently presented that simulates resource-dependent plasticity of plant architecture. This study introduces a new methodology for crop parameter optimization against measured data called multi-fitting, validates the calibrated model for maize with independent field data, and describes a technique for 3D visualization of outputs. • Methods Maize was grown near Beijing during the 2000, 2001 and 2003 (two sowing dates) summer seasons in a block design with four to five replications. Detailed morphological and topological observations were made on the plant architecture throughout the development of the four crops. Data obtained in 2000 was used to establish target files for parameter optimization using the generalized least square method, and parameter accuracy was evaluated by coefficient of variance. In situ plant digitization was used to establish 3D symbol files for organs that were then used to translate model outputs directly into 3D representations for each time step of model execution. •Key Results and Conclusions Multi-fitting against several target files obtained at different growth stages gave better parameter accuracy than single fitting at maturity only, and permitted extracting generic organ expansion kinetics from the static observations. The 2000 model gave excellent predictions of plant architecture and vegetative growth for the other three seasons having different temperature regimes, but predictions of inter-seasonal variability of

    Background and Aims Plant population density (PPD) influences plant growth greatly. Functional–structural plant models such as GREENLAB can be used to simulate plant development and growth and PPD effects on plant functioning and architectural behaviour can be investigated. This study aims to evaluate the ability of GREENLAB to predict maize growth and development at different PPDs. Methods Two field experiments were conducted on irrigated fields in the North China Plain with a block design of four replications. Each experiment included three PPDs: 2·8, 5·6 and 11·1 plants m−2. Detailed observations were made on the dimensions and fresh biomass of above-ground plant organs for each phytomer throughout the seasons. Growth stage-specific target files (a description of plant organ weight and dimension according to plant topological structure) were established from the measured data required for GREENLAB parameterization. Parameter optimization was conducted using a generalized least square method for the entire growth cycles for all PPDs and years. Data from in situ plant digitization were used to establish geometrical symbol files for organs that were then applied to translate model output directly into 3-D representation for each time step of the model execution. Key Results The analysis indicated that the parameter values of organ sink variation function, and the values of most of the relative sink strength parameters varied little among years and PPDs, but the biomass production parameter, computed plant projection surface and internode relative sink strength varied with PPD. Simulations of maize plant growth based on the fitted parameters were reasonably good as indicated by the linearity and slopes similar to unity for the comparison of simulated and observed values. Based on the parameter values fitted from different PPDs, shoot (including vegetative and reproductive parts of the plant) and cob fresh biomass for other PPDs were simulated. Three

    Background and Aims The dynamical system of plant growth GREENLAB was originally developed for individual plants, without explicitly taking into account interplant competition for light. Inspired by the competition models developed in the context of forest science for mono-specific stands, we propose to adapt the method of crown projection onto the x–y plane to GREENLAB, in order to study the effects of density on resource acquisition and on architectural development. Methods The empirical production equation of GREENLAB is extrapolated to stands by computing the exposed photosynthetic foliage area of each plant. The computation is based on the combination of Poisson models of leaf distribution for all the neighbouring plants whose crown projection surfaces overlap. To study the effects of density on architectural development, we link the proposed competition model to the model of interaction between functional growth and structural development introduced by Mathieu (2006, PhD Thesis, Ecole Centrale de Paris, France). Key Results and Conclusions The model is applied to mono-specific field crops and forest stands. For high-density crops at full cover, the model is shown to be equivalent to the classical equation of field crop production ( Howell and Musick, 1985, in Les besoins en eau des cultures; Paris: INRA Editions). However, our method is more accurate at the early stages of growth (before cover) or in the case of intermediate densities. It may potentially account for local effects, such as uneven spacing, variation in the time of plant emergence or variation in seed biomass. The application of the model to trees illustrates the expression of plant plasticity in response to competition for light. Density strongly impacts on tree architectural development through interactions with the source–sink balances during growth. The effects of density on tree height and radial growth that are commonly observed in real stands appear as emerging properties of the model

    There is a large gap between the production and demand for energy from alternative fuel and alternative renewable energy sources. The sustainability of humanity, as we know it, directly depends on the ability to secure affordable fuel, food, and freshwater. NASA Glenn Research Center (Glenn) has initiated a laboratory pilot study on using biofuels as viable alternative fuel resources for the field of aviation, as well as utilizing wind and solar technology as alternative renewable energy resources. The GreenLab Research Facility focuses on optimizing biomass feedstock using algae and halophytes as the next generation of renewable aviation fuels. The unique approach in this facility helps achieve optimal biomass feedstock through climatic adaptation of balanced ecosystems that do not use freshwater, compete with food crops, or use arable land. In addition, the GreenLab Research Facility is powered, in part, by alternative and renewable energy sources, reducing the major environmental impact of present electricity sources. The ultimate goal is to have a 100 percent clean energy laboratory that, when combined with biomass feedstock research, has the framework in place for a self-sustainable renewable energy ecosystem that can be duplicated anywhere in the world and can potentially be used to mitigate the shortage of food, fuel, and water. This paper describes the GreenLab Research Facility at Glenn and its power and energy sources, and provides recommendations for worldwide expansion and adoption of the facility s concept.

    Intermittency in urban water supply affects hundreds of millions of people in cities around the world, impacting water quality and infrastructure. Building on previous work to dynamically model the transient flows in water distribution networks undergoing frequent filling and emptying, we now consider the hydraulic implications of uncertain input data. Water distribution networks undergoing intermittent supply are often poorly mapped, and household metering frequently ranges from patchy to nonexistent. In the face of uncertain pipe material, pipe slope, network connectivity, and outflow, we investigate how uncertainty affects dynamical modeling results. We furthermore identify which parameters exert the greatest influence on uncertainty, helping to prioritize data collection.

    Structural vector autoregressive models (VARs) hold great potential for psychological science, particularly for time series data analysis. They capture the magnitude, direction of influence, and temporal (lagged and contemporaneous) nature of relations among variables. Unified structural equation modeling (uSEM) is an optimal structural VAR instantiation, according to large-scale simulation studies, and it is implemented within an SEM framework. However, little is known about the uniqueness of uSEM results. Thus, the goal of this study was to investigate whether multiple solutions result from uSEM analysis and, if so, to demonstrate ways to select an optimal solution. This was accomplished with two simulated data sets, an empirical data set concerning children's dyadic play, and modifications to the group iterative multiple model estimation (GIMME) program, which implements uSEMs with group- and individual-level relations in a data-driven manner. Results revealed multiple solutions when there were large contemporaneous relations among variables. Results also verified several ways to select the correct solution when the complete solution set was generated, such as the use of cross-validation, maximum standardized residuals, and information criteria. This work has immediate and direct implications for the analysis of time series data and for the inferences drawn from those data concerning human behavior. PMID:27093380

    2012-01-01

    Species distribution models (SDMs) are widespread in ecology and conservation biology, but their accuracy can be lowered by non-environmental (noisy) absences that are common in species occurrence data. Here we propose an iterative ensemble modelling (IEM) method to deal with noisy absences and hence improve the predictive reliability of ensemble modelling of species distributions. In the IEM approach, outputs of a classical ensemble model (EM) were used to update the raw occurrence data. The revised data was then used as input for a new EM run. This process was iterated until the predictions stabilized. The outputs of the iterative method were compared to those of the classical EM using virtual species. The IEM process tended to converge rapidly. It increased the consensus between predictions provided by the different methods as well as between those provided by different learning data sets. Comparing IEM and EM showed that for high levels of non-environmental absences, iterations significantly increased prediction reliability measured by the Kappa and TSS indices, as well as the percentage of well-predicted sites. Compared to EM, IEM also reduced biases in estimates of species prevalence. Compared to the classical EM method, IEM improves the reliability of species predictions. It particularly deals with noisy absences that are replaced in the data matrices by simulated presences during the iterative modelling process. IEM thus constitutes a promising way to increase the accuracy of EM predictions of difficult-to-detect species, as well as of species that are not in equilibrium with their environment.

    Our ageing medical workforce poses many challenges, not the least of which is acknowledging the contributions of ageing practitioners who continue to practise safely and competently while ensuring that those who are incompetent by virtue of impairment are identified, assessed and either rehabilitated or encouraged to retire. Hitherto, there has been little attempt to review approaches to impairment on a national basis in Australia, let alone with a focus on older doctors. Information regarding pathways for dealing with impairment was obtained from the websites and confirmed by representatives of regulatory bodies of every state or territory in Australia. Using a prevention model we outline the current Australian regulatory processes, address some of the barriers and suggest some solutions to dealing with the older impaired doctor. Much of the focus in dealing with the older impaired doctor is tertiary prevention based, that is, reducing the negative influence of established impairment. There is some uniformity in the way that Australian regulatory bodies deal with impairment that espouses the dual goals of protecting the public and rehabilitating the doctor. The approach is typically individualized and multi-levelled, beginning with assessment followed by rehabilitation where appropriate. A range of secondary and primary prevention measures is proposed for dealing with the problem of the older impaired doctor. These include educating the medical community, encouraging early notification and facilitating career planning and timely retirement of older doctors. This will have benefits both in protecting the public as well as preventing an undignified and humiliating end to often-unblemished careers in medicine. PMID:18028084

    While fuzzy specialists commonly use homogeneous experts' knowledge to construct fuzzy models, it is much more difficult to deal with knowledge elicited from a heterogeneous group of experts. This issue is exemplified in the area of sustainable rangeland management (SRM). One way to deal with the diversity of opinions is to develop a fuzzy system for all experts and to combine all these, the so-called primary systems, into one multi-fuzzy model. To derive each of the primary fuzzy systems, several semi-structured interviews were held in three different areas of the Fars province in Southwest Iran using the knowledge of a group of administrative experts. To obtain the final output of the multi-fuzzy model, we applied different 'voting' methods. The first method simply uses the arithmetic average of the primary outputs as the final output of the multi-fuzzy model. This final output represents an estimation of the right rate of stocking (RRS). We also propose other (un)supervised voting methods. Most importantly, by harmonising the primary outputs such that outliers get less emphasis, we introduce an unsupervised voting method for calculating a weighted estimate of the RRS. This harmonising method is expected to provide a new useful tool for policymakers dealing with heterogenity in experts' opinions: it is especially useful where limited field data are available and one is forced to rely on experts' knowledge only. By constructing the three fuzzy models based on the elicitation of heterogeneous experts' knowledge, our study shows the multidimensional vaguenesses that exist in SRM. Finally, by comparing the final RRS with its common values, this study strongly points to the existence of overgrazing in pastures in the three regions of the Fars province in Southwest Iran.

  14. A Leasing Model to Deal with Partial Failures in Mobile Ad Hoc Networks

    In mobile ad hoc networks (MANETs) many partial failures are the result of temporary network partitions due to the intermittent connectivity of mobile devices. Some of these failures will be permanent and require application-level failure handling. However, it is impossible to distinguish a permanent from a transient failure. Leasing provides a solution to this problem based on the temporal restriction of resources. But to date no leasing model has been designed specifically for MANETs. In this paper, we identify three characteristics required for a leasing model to be usable in a MANET, discuss the issues with existing leasing models and then propose the leased object references model, which integrates leasing with remote object references. In addition, we describe an implementation of the model in the programming language AmbientTalk. Leased object references provide an extensible framework that allows programmers to express their own leasing patterns and enables both lease holders (clients) and lease grantors (services) to deal with permanent failures.

    Landscape genetics lacks explicit methods for dealing with the uncertainty in landscape resistance estimation, which is particularly problematic when sample sizes of individuals are small. Unless uncertainty can be quantified, valuable but small data sets may be rendered unusable for conservation purposes. We offer a method to quantify uncertainty in landscape resistance estimates using multimodel inference as an improvement over single model-based inference. We illustrate the approach empirically using co-occurring, woodland-preferring Australian marsupials within a common study area: two arboreal gliders (Petaurus breviceps, and Petaurus norfolcensis) and one ground-dwelling antechinus (Antechinus flavipes). First, we use maximum-likelihood and a bootstrap procedure to identify the best-supported isolation-by-resistance model out of 56 models defined by linear and non-linear resistance functions. We then quantify uncertainty in resistance estimates by examining parameter selection probabilities from the bootstrapped data. The selection probabilities provide estimates of uncertainty in the parameters that drive the relationships between landscape features and resistance. We then validate our method for quantifying uncertainty using simulated genetic and landscape data showing that for most parameter combinations it provides sensible estimates of uncertainty. We conclude that small data sets can be informative in landscape genetic analyses provided uncertainty can be explicitly quantified. Being explicit about uncertainty in landscape genetic models will make results more interpretable and useful for conservation decision-making, where dealing with uncertainty is critical.

    The label switching problem occurs as a result of the nonidentifiability of posterior distribution over various permutations of component labels when using Bayesian approach to estimate parameters in mixture models. In the cases where the number of components is fixed and known, we propose a relabelling algorithm, an allocation variable-based (denoted by AVP) probabilistic relabelling approach, to deal with label switching problem. We establish a model for the posterior distribution of allocation variables with label switching phenomenon. The AVP algorithm stochastically relabel the posterior samples according to the posterior probabilities of the established model. Some existing deterministic and other probabilistic algorithms are compared with AVP algorithm in simulation studies, and the success of the proposed approach is demonstrated in simulation studies and a real dataset.

    People suffering from mental illness are increasingly referred to the domestic violence court. Yet the typical diversion programs available, including batterer's intervention programs, are inappropriate for those with serious mental illness. As a result, the Miami-Dade Domestic Violence Court has developed a new approach for dealing with this population that applies mental health court techniques in domestic violence court. This article will describe and discuss this pioneering model. It also will situate this model within the context of other problem-solving courts and discuss how the court uses principles and approaches of therapeutic jurisprudence. The paper presents some preliminary data that describe the social and legal characteristics of 20 defendants in the Domestic Violence Mental Health Court followed over a two year period between 2005 and 2007.

    Due to the rise of criminal, civil and administrative judicial situations involving people lacking valid identity documents, age estimation of living persons has become an important operational procedure for numerous forensic and medicolegal services worldwide. The chronological age of a given person is generally estimated from the observed degree of maturity of some selected physical attributes by means of statistical methods. However, their application in the forensic framework suffers from some conceptual and practical drawbacks, as recently claimed in the specialised literature. The aim of this paper is therefore to offer an alternative solution for overcoming these limits, by reiterating the utility of a probabilistic Bayesian approach for age estimation. This approach allows one to deal in a transparent way with the uncertainty surrounding the age estimation process and to produce all the relevant information in the form of posterior probability distribution about the chronological age of the person under investigation. Furthermore, this probability distribution can also be used for evaluating in a coherent way the possibility that the examined individual is younger or older than a given legal age threshold having a particular legal interest. The main novelty introduced by this work is the development of a probabilistic graphical model, i.e. a Bayesian network, for dealing with the problem at hand. The use of this kind of probabilistic tool can significantly facilitate the application of the proposed methodology: examples are presented based on data related to the ossification status of the medial clavicular epiphysis. The reliability and the advantages of this probabilistic tool are presented and discussed. PMID:25794687

    Ecosystem models have been developed for assessment and management in a wide variety of environments. As model complexity increases, it becomes more difficult to trace how imperfect knowledge of internal model parameters, data inputs, or relationships among parameters might impact model results, affecting predictions and subsequent management decisions. Sensitivity analysis is an essential component of model evaluation, particularly when models are used to make management decisions. Results should be expressed as probabilities and should realistically account for uncertainty. When models are particularly complex, this can be difficult to do and to present in ways that do not obfuscate essential results. We conducted a sensitivity analysis of the Ecosystem Diagnosis and Treatment (EDT) model, which predicts salmon productivity and capacity as a function of ecosystem conditions. We used a novel "structured sensitivity analysis" approach that is particularly useful for very complex models or those with an abundance of interconnected parameters. We identified small, medium, and large plausible ranges for both input data and model parameters. Using a Monte Carlo approach, we explored the variation in output, prediction intervals, and sensitivity indices, given these plausible input distributions. The analyses indicated that, as a consequence of internal parameter uncertainty, EDT productivity and capacity predictions lack the precision needed for many management applications. However, EDT prioritization of reaches for preservation or restoration was more robust to given input uncertainties, indicating that EDT may be more useful as a relative measure of fish performance than as an absolute measure. Like all large models, if EDT output is to be used as input to other models or management tools it is important to explicitly incorporate the uncertainty and sensitivity analyses into such secondary analyses. Sensitivity analyses should become standard operating procedure for

    Earth System Models of Intermediate Complexity (EMICs) are popular tools for palaeo climate simulations. Recent studies applied these models in comparison to terrestrial proxy records and aimed to reconstruct changes in seasonal climate forced by altered ocean circulation patterns. To strengthen this powerful methodology, we argue that the magnitude of the simulated atmospheric changes should be considered in relation to the internal variability of both the climate system and the intermediate complexity model. To attribute a shift in modelled climate to reality, this ‘signal' should be detectable above the ‘noise' related to the internal variability of the climate system and the internal variability of the model. Both noise and climate signals vary over the globe and change with the seasons. We therefore argue that spatial explicit fields of noise should be considered in relation to the strengths of the simulated signals at a seasonal timescale. We approximated total noise on terrestrial temperature and precipitation from a 29 member simulation with the EMIC PUMA-2 and global temperature and precipitation datasets. To illustrate this approach, we calculate Signal-to-Noise-Ratios (SNRs) in terrestrial temperature and precipitation on simulations of an El Niño warm event, a phase change in Atlantic Meridional Oscillation (AMO) and a Heinrich cooling event. The results of the El Niño and AMO simulations indicate that the chance to accurately detect a climate signal increases with increasing SNRs. Considering the regions and seasons with highest SNRs, the simulated El Niño anomalies show good agreement with observations (r² = 0.8 and 0.6 for temperature and precipitation at SNRs > 4). The AMO signals rarely surpass the noise levels and remain mostly undetected. The simulation of a Heinrich event predicts highest SNRs for temperature (up to 10) over Arabia and Russia during Boreal winter and spring. Highest SNRs for precipitation (up to 12) are predicted over

    Although uncertainty about structures of environmental models (conceptual uncertainty) has been recognised often to be the main source of uncertainty in model predictions, it is rarely considered in environmental modelling. Rather, formal uncertainty analyses have traditionally focused on model parameters and input data as the principal source of uncertainty in model predictions. The traditional approach to model uncertainty analysis that considers only a single conceptual model, fails to adequately sample the relevant space of plausible models. As such, it is prone to modelling bias and underestimation of model uncertainty. In this paper we review a range of strategies for assessing structural uncertainties. The existing strategies fall into two categories depending on whether field data are available for the variable of interest. Most research attention has until now been devoted to situations, where model structure uncertainties can be assessed directly on the basis of field data. This corresponds to a situation of `interpolation'. However, in many cases environmental models are used for `extrapolation' beyond the situation and the field data available for calibration. A framework is presented for assessing the predictive uncertainties of environmental models used for extrapolation. The key elements are the use of alternative conceptual models and assessment of their pedigree and the adequacy of the samples of conceptual models to represent the space of plausible models by expert elicitation.

    To better manage living marine resources (LMRs), it has become clear that ecosystem-based fisheries management (EBFM) is a desired approach. To do EBFM, one of the key tools will be to use ecosystem models. To fully use ecosystem models and have their outputs adopted, there is an increasingly recognized need to address uncertainty associated with such modeling activities. Here we characterize uncertainty as applied to ecosystem models into six major factors, including: natural variability; observation error; inadequate communication among scientists, decision-makers and stakeholders; the structural complexity of the model(s) used; outcome uncertainty; and unclear management objectives. We then describe best practices to address each of these uncertainties as they particularly apply to ecosystem models being used in a LMR management context. We also present case studies to highlight examples of how these best practices have been implemented. Although we acknowledge that this work was compiled by ecosystem modelers in an LMR management context primarily for other ecosystem modelers, the principles and practices described herein are also germane for managers, stakeholders and other natural resource management communities.

    In structural engineering, model updating is often used for non-destructive damage assessment: by calibrating stiffness parameters of finite element models based on experimentally obtained (modal) data, structural damage can be identified, quantified and located. However, the model updating problem is an inverse problem prone to ill-posedness and ill-conditioning. This means the problem is extremely sensitive to small errors, which may potentially detract from the method's robustness and reliability. As many errors or uncertainties are present in model updating, both regarding the measurements as well as the employed numerical model, it is important to take these uncertainties suitably into account. This paper aims to provide an overview of the available approaches to this end, where two methods are treated in detail: a non-probabilistic fuzzy approach and a probabilistic Bayesian approach. These methods are both elaborated for the specific case of vibration-based finite element model updating for damage assessment purposes.

    High resolution rainfall fields contain numerous zeros (i.e pixels or time steps with no rain) which are either real or spurious that is to say associated with the limit of detection of the rainfall measurement device. The Universal multifractal (UM) framework, which is commonly used to analyse and simulate geophysical fields exhibiting extreme variability over wide range of scales with the help of reduced number of parameters, does not enable to properly represent theses zeros. It has been shown that not taking them into account can worsen the quality of the scaling and lead to severe bias in the estimates of UM parameters. In the literature, there are mainly two models suggested for representing the zeros of the rainfall. First the so-called beta-model option, which basically consists in multiplying a multifractal field by an independent binary support (the portion of the field where there actually is some rain) generated with the help of a beta-model (i.e. a cascade model leading to a set exhibiting a pre-defined fractal dimension). Second the threshold option where the field is simply truncated at the maximum resolution. There are serious limitations with both options. For example the independence assumption in the beta-model option is not realistic and in the threshold option there is no "real" (i.e. associated with physical processes) zeros or small values. In this paper we propose a new toy model which basically consists in merging both models. It is a UM discrete cascade process, where at each step if the simulated intensity is below a given level (defined in a scale invariant manner), it only has a predetermined probability to survive and is otherwise set to zero. It would represent a physical limit to rainfall processes. A threshold can then be implemented at the maximum resolution to model the limit of detection of the rainfall measurement device. With the help of theoretical considerations and numerical simulations, we show that this simple toy model

  9. Modeling the spatial variability of dispersivity to deal with anomalous mass transport in the subsurface

    The limitations of the classical Advection-Dispersion Equation (ADE) approach to model mass transport remain a subject of research. The term anomalous transport is usually applied when the ADE fails to reproduce real field or lab experiments tracer tests data. Some authors address this limitation using high-resolution heterogeneous hydraulic conductivity (K) fields. Besides, the non-Fickian behavior of transport is another issue addressed. However, the effects of the spatial variability of dispersivity, and the influence of the model support scale on this property, have been rarely studied. The lack of experimental knowledge on the dispersivity behavior leads to model this basic parameter as an averaged calibrated parameter highly dependent on the model discretization size. In order to study the local behavior of the dispersivity a porous medium tank was designed and built at the Technical University of Valencia (Spain). This paper presents new results and conclusions obtained from the experiments conducted in this lab prototype. The steady flow through the porous medium tank lab is quasi-2D, and the K field imitates the patterns of spatial variability found in a real and highly heterogeneous formation (MADE2 site). The tracer tests are run using a conservative dye tracer and the tank is monitored by a grid of pressure transducers and taking digital images that are processed to map the evolution of solute concentrations in the tank. The set of exhaustive head and concentration data is used to compute detail local information of the effective dispersivity field at different time steps, and at different support scales. The analysis of results shows that the dispersivity field displays patterns of spatial variability related with the physical nature of the local material and also with the local evolution of concentrations at every grid block. We have found that the anomalous transport behavior observed in the lab tank can be accurately modeled using the classical ADE

  10. How can we deal with ANN in flood forecasting? As a simulation model or updating kernel!

    NASA Astrophysics Data System (ADS)

    Hassan Saddagh, Mohammad; Javad Abedini, Mohammad

    2010-05-01

    Flood forecasting and early warning, as a non-structural measure for flood control, is often considered to be the most effective and suitable alternative to mitigate the damage and human loss caused by flood. Forecast results which are output of hydrologic, hydraulic and/or black box models should secure accuracy of flood values and timing, especially for long lead time. The application of the artificial neural network (ANN) in flood forecasting has received extensive attentions in recent years due to its capability to capture the dynamics inherent in complex processes including flood. However, results obtained from executing plain ANN as simulation model demonstrate dramatic reduction in performance indices as lead time increases. This paper is intended to monitor the performance indices as it relates to flood forecasting and early warning using two different methodologies. While the first method employs a multilayer neural network trained using back-propagation scheme to forecast output hydrograph of a hypothetical river for various forecast lead time up to 6.0 hr, the second method uses 1D hydrodynamic MIKE11 model as forecasting model and multilayer neural network as updating kernel to monitor and assess the performance indices compared to ANN alone in light of increase in lead time. Results presented in both graphical and tabular format indicate superiority of MIKE11 coupled with ANN as updating kernel compared to ANN as simulation model alone. While plain ANN produces more accurate results for short lead time, the errors increase expeditiously for longer lead time. The second methodology provides more accurate and reliable results for longer forecast lead time.

  11. Dealing with unquantifiable uncertainties in landslide modelling for urban risk reduction in developing countries

    2016-04-01

    Landslides have many negative economic and societal impacts, including the potential for significant loss of life and damage to infrastructure. Slope stability assessment can be used to guide decisions about the management of landslide risk, but its usefulness can be challenged by high levels of uncertainty in predicting landslide occurrence. Prediction uncertainty may be associated with the choice of model that is used to assess slope stability, the quality of the available input data, or a lack of knowledge of how future climatic and socio-economic changes may affect future landslide risk. While some of these uncertainties can be characterised by relatively well-defined probability distributions, for other uncertainties, such as those linked to climate change, no probability distribution is available to characterise them. This latter type of uncertainty, often referred to as deep uncertainty, means that robust policies need to be developed that are expected to perform acceptably well over a wide range of future conditions. In our study the impact of deep uncertainty on slope stability predictions is assessed in a quantitative and structured manner using Global Sensitivity Analysis (GSA) and the Combined Hydrology and Stability Model (CHASM). In particular, we use several GSA methods including the Method of Morris, Regional Sensitivity Analysis and Classification and Regression Trees (CART), as well as advanced visualization tools, to assess the combination of conditions that may lead to slope failure. Our example application is a slope in the Caribbean, an area that is naturally susceptible to landslides due to a combination of high rainfall rates during the hurricane season, steep slopes, and highly weathered residual soils. Rapid unplanned urbanisation and changing climate may further exacerbate landslide risk in the future. Our example shows how we can gain useful information in the presence of deep uncertainty by combining physically based models with GSA in

  12. A new method for dealing with measurement error in explanatory variables of regression models.

    2004-03-01

    We introduce a new method, moment reconstruction, of correcting for measurement error in covariates in regression models. The central idea is similar to regression calibration in that the values of the covariates that are measured with error are replaced by "adjusted" values. In regression calibration the adjusted value is the expectation of the true value conditional on the measured value. In moment reconstruction the adjusted value is the variance-preserving empirical Bayes estimate of the true value conditional on the outcome variable. The adjusted values thereby have the same first two moments and the same covariance with the outcome variable as the unobserved "true" covariate values. We show that moment reconstruction is equivalent to regression calibration in the case of linear regression, but leads to different results for logistic regression. For case-control studies with logistic regression and covariates that are normally distributed within cases and controls, we show that the resulting estimates of the regression coefficients are consistent. In simulations we demonstrate that for logistic regression, moment reconstruction carries less bias than regression calibration, and for case-control studies is superior in mean-square error to the standard regression calibration approach. Finally, we give an example of the use of moment reconstruction in linear discriminant analysis and a nonstandard problem where we wish to adjust a classification tree for measurement error in the explanatory variables.

    The authors were involved in the use of some Mathematical Decision Models, MDM, to improve knowledge and planning about some large natural or administrative areas for which natural soils, climate, and agro and forest uses where main factors, but human resources and results were important, natural hazards being relevant. In one line they have contributed about qualification of lands of the Community of Madrid, CM, administrative area in centre of Spain containing at North a band of mountains, in centre part of Iberian plateau and river terraces, and also Madrid metropolis, from an official study of UPM for CM qualifying lands using a FAO model from requiring minimums of a whole set of Soil Science criteria. The authors set first from these criteria a complementary additive qualification, and tried later an intermediate qualification from both using fuzzy logic. The authors were also involved, together with colleagues from Argentina et al. that are in relation with local planners, for the consideration of regions and of election of management entities for them. At these general levels they have adopted multi-criteria MDM, used a weighted PROMETHEE, and also an ELECTRE-I with the same elicited weights for the criteria and data, and at side AHP using Expert Choice from parallel comparisons among similar criteria structured in two levels. The alternatives depend on the case study, and these areas with monsoon climates have natural hazards that are decisive for their election and qualification with an initial matrix used for ELECTRE and PROMETHEE. For the natural area of Arroyos Menores at South of Rio Cuarto town, with at North the subarea of La Colacha, the loess lands are rich but suffer now from water erosions forming regressive ditches that are spoiling them, and use of soils alternatives must consider Soil Conservation and Hydraulic Management actions.

    2004-09-01

    The headlines are filled with the sorry tales of companies like Vivendi and AOL Time Warner that tried to use mergers and acquisitions to grow big fast or transform fundamentally weak business models. But, drawing on extensive data and experience, the authors conclude that major deals make sense in only two circumstances: when they reinforce a company's existing basis of competition or when they help a company make the shift, as the industry's competitive base changes. In most stable industries, the authors contend, only one basis--superior cost position, brand power, consumer loyalty, real-asset advantage, or government protection--leads to industry leadership, and companies should do only those deals that bolster a strategy to capitalize on that competitive base. That's what Kellogg did when it acquired Keebler. Rather than bow to price pressures from lesser players, Kellogg sought to strengthen its existing basis of competition--its brand--through Keebler's innovative distribution system. A company coping with a changing industry should embark on a series of acquisitions (most likely coupled with divestitures) aimed at moving the firm to the new competitive basis. That's what Comcast did when changes in government regulations fundamentally altered the broadcast industry. In such cases, speed is essential, the investments required are huge, and half-measures can be worse than nothing at all. Still, the research shows, successful acquirers are not those that try to swallow a single, large, supposedly transformative deal but those that go to the M&A table often and take small bites. Deals can fuel growth--as long as they're anchored in the fundamental way money is made in your industry. Fail to understand that and no amount of integration planning will keep you and your shareholders from bearing the high cost of your mistakes. PMID:15449861

    of the hydrogen-like ions, however, the underlying 'mathematics' is not always that easy to deal with. Apart from the well-known level structure of these ions as obtained from either the Schrödinger or Dirac equation, namely, a great deal of other properties are often needed. These properties are related to the interaction of bound electron(s) with external particles and fields and, hence, require to evaluate transition amplitudes, including wavefunctions and (transition) operators of quite different complexity. Although various special functions, such as the Laguerre polynomials, spherical harmonics, Whittaker functions, or the hypergeometric functions of various kinds can be used in most cases in order to express these amplitudes in a concise form, their derivation is time consuming and prone for making errors. In addition to their complexity, moreover, there exist a large number of mathematical relations among these functions which are difficult to remember in detail and which have often hampered quantitative studies in the past. Method of solution: A set of MAPLE procedures is developed which provides both the nonrelativistic and relativistic (analytical) solutions of the 'hydrogen atom model' and which facilitates the symbolic evaluation of various transition amplitudes. Restrictions onto the complexity of the problem: Over the past decades, a large number of representations have been worked out for the hydrogenic wave and Green's functions, using different variables and coordinates [2]. From these, the position-space representation in spherical coordinates is certainly of most practical interest and has been used as the basis of the present implementation. No attempt has been made by us so far to provide the wave and Green's functions also in momentum space, for which the relativistic momentum functions would have to be constructed numerically. Although the DIRAC program supports both symbolic and numerical computations, the latter one are based on MAPLE

  19. Creating a Mathematical Model for Solving Chatter and Dealing the Problems Concerning the Maximum Allowable Size of a Machining Chip

    NASA Astrophysics Data System (ADS)

    Ondrášek, J.

    The paper deals with the issues of self-excited vibration. Such vibration occurs in those systems in which an internal source continuously exists from which the system draws power to maintain or even increase the amplitude of vibration when this take-off is controlled by the oscillating motion of the system itself. Thus, this energy source considerably influences the dynamic and stability features of the system. An example of such a system is a machine tool during machining as well when a part of the energy of the cutting process in chip machining can be changed into energy that will be vibrating the machine as a whole. The vibrations are then shown with a strong machined surface waviness and are usually accompanied by noise. In general, it can be determined the range of cutting conditions in which, when applying them, no chatter will occur, i.e. the cutting process is stable. One of the ways of such a determining is a stability lobe diagram e.g. which expresses the dependence of chip thickness on the speed of a workpiece. The subject of this paper is a possible procedure and approach when creating stability lobe diagrams.

    Ideology and attitudes of Latino church leaders in the United States toward HIV/AIDS are explored. A qualitative approach utilized with emergent categories including: a desire within the Latino church for greater acceptance of HIV/AIDS sufferers, the supposed contaminating influence of HIV/AIDS individuals over other church members, and the feelings of helplessness many church members experience in relation to the HIV/AIDS crisis. Understanding ideological resistance that prevents engagement is here identified and a strategy of empowerment of church leaders is recommended to overcome it including: adopting a strengths-oriented service model that focuses on resources religious denominations already have, as opposed to a financially driven, medically oriented service model that highlights what churches often do not have; church leaders educating health care agencies on how to use religious beliefs to motivate church members to work on behalf of HIV/AIDS patients; the power of doctrinal ideology in affecting church and civil society's response to HIV/AIDS.

    Pursuing a merger or acquisition is inherently difficult. Things get even harder when executives are blind to their own faulty assumptions, say Lovallo--a professor at the University of Western Australia Business School and a senior adviser to McKinsey--and three of his McKinsey colleagues. The authors identify biases that can surface at each step of the M&A process and provide practical tips for rising above them--an approach they call targeted debiasing. During the preliminary due-diligence stage, biases abound. To overcome the confirmation bias, aggressively seek evidence that challenges your initial hypothesis about a deal. The best medicine for overconfidence in identifying revenue and cost synergies is to learn from precedents at your firm and others. Avoiding underestimation of cultural differences between your company and the target requires understanding the differences in the ways people interact at each organization. Misjudging the time and resources you need is at the core of the planning fallacy, which you can elude by formally identifying best practices and continually revisiting them. Finally, dilute conflict of interest by soliciting dispassionate external expertise. The bidding phase is vulnerable to the winner's curse, a phenomenon common in auctions. To avoid paying too much for a target, actively generate alternatives to the deal under consideration and develop a set of bidding cutoff rules. After offering an initial bid, deal makers are susceptible to anchoring, whereby they remain attached to their original price estimate, and to the sunk cost fallacy that they've invested too much to stop now. The secret to overcoming both: Use your newly available access to the target's books to better assess the investment case--and change your tune accordingly. PMID:18283919

    It is useful for authors to learn to deal with returned manuscripts with a rejection decision or a request for revision. Common reasons for rejection include contents outside the scope of the journal or inappropriate for the journal, incomplete submission, poor methodology, faulty experimental design, major flaws in the interpretation of results, extremely poor writing, and duplicated or plagiarised work. Authors should use the editor's and reviewers' comments to improve their manuscripts and resubmit elsewhere. Common reasons for revision requests include minor faults in the methodology, minor inaccuracies in data, inconsistencies among different sections of the manuscript, faulty deductions, data that do not support the conclusions, excessive data or text, poor or excessive illustrations, and poor but salvageable writing. A request for revision should be viewed positively, as it means that there is a possibility that the manuscript may still be potentially publishable, provided that all the editor's and reviewers' comments are addressed.

  10. Quantitative Genetics and Functional–Structural Plant Growth Models: Simulation of Quantitative Trait Loci Detection for Model Parameters and Application to Potential Yield Optimization

    Letort, Véronique; Mahe, Paul; Cournède, Paul-Henry; de Reffye, Philippe; Courtois, Brigitte

    2008-01-01

    Background and Aims Prediction of phenotypic traits from new genotypes under untested environmental conditions is crucial to build simulations of breeding strategies to improve target traits. Although the plant response to environmental stresses is characterized by both architectural and functional plasticity, recent attempts to integrate biological knowledge into genetics models have mainly concerned specific physiological processes or crop models without architecture, and thus may prove limited when studying genotype × environment interactions. Consequently, this paper presents a simulation study introducing genetics into a functional–structural growth model, which gives access to more fundamental traits for quantitative trait loci (QTL) detection and thus to promising tools for yield optimization. Methods The GREENLAB model was selected as a reasonable choice to link growth model parameters to QTL. Virtual genes and virtual chromosomes were defined to build a simple genetic model that drove the settings of the species-specific parameters of the model. The QTL Cartographer software was used to study QTL detection of simulated plant traits. A genetic algorithm was implemented to define the ideotype for yield maximization based on the model parameters and the associated allelic combination. Key Results and Conclusions By keeping the environmental factors constant and using a virtual population with a large number of individuals generated by a Mendelian genetic model, results for an ideal case could be simulated. Virtual QTL detection was compared in the case of phenotypic traits – such as cob weight – and when traits were model parameters, and was found to be more accurate in the latter case. The practical interest of this approach is illustrated by calculating the parameters (and the corresponding genotype) associated with yield optimization of a GREENLAB maize model. The paper discusses the potentials of GREENLAB to represent environment × genotype

    2005-03-01

    Heterogeneity can be dealt with by defining homogeneous equivalent properties, known as averaging, or by trying to describe the spatial variability of the rock properties from geologic observations and local measurements. The techniques available for these descriptions are mostly continuous Geostatistical models, or discontinuous facies models such as the Boolean, Indicator or Gaussian-Threshold models and the Markov chain model. These facies models are better suited to treating issues of rock strata connectivity, e.g. buried high permeability channels or low permeability barriers, which greatly affect flow and, above all, transport in aquifers. Genetic models provide new ways to incorporate more geology into the facies description, an approach that has been well developed in the oil industry, but not enough in hydrogeology. The conclusion is that future work should be focused on improving the facies models, comparing them, and designing new in situ testing procedures (including geophysics) that would help identify the facies geometry and properties. A world-wide catalog of aquifer facies geometry and properties, which could combine site genesis and description with methods used to assess the system, would be of great value for practical applications.

  18. PEG tubes: dealing with complications.

    PubMed

    Malhi, Hardip; Thompson, Rosie

    A percutaneous endoscopic gastronomy tube can be used to deliver nutrition, hydration and medicines directly into the patient's stomach. Patients will require a tube if they are unable to swallow safely, putting them at risk of aspiration of food, drink and medicines into their lungs. It is vital that nurses are aware of the complications that may arise when caring for a patient with a PEG tube. It is equally important that nurses know how to deal with these complications or from where tc seek advice. This article provides a quick troubleshooting guide to help nurses deal with complications that can arise with PEG feeding. PMID:26016095

  2. Dealing with uncertainties - communication between disciplines

    Overbeek, Bernadet; Bessembinder, Janette

    2013-04-01

    Climate adaptation research inevitably involves uncertainty issues - whether people are building a model, using climate scenarios, or evaluating policy processes. However, do they know which uncertainties are relevant in their field of work? And which uncertainties exist in the data from other disciplines that they use (e.g. climate data, land use, hydrological data) and how they propagate? From experiences in Dutch research programmes on climate change in the Netherlands we know that disciplines often deal differently with uncertainties. This complicates communication between disciplines and also with the various users of data and information on climate change and its impacts. In October 2012 an autumn school was organized within the Knowledge for Climate Research Programme in the Netherlands with as central theme dealing with and communicating about uncertainties, in climate- and socio-economic scenarios, in impact models and in the decision making process. The lectures and discussions contributed to the development of a common frame of reference (CFR) for dealing with uncertainties. The common frame contains the following: 1. Common definitions (typology of uncertainties, robustness); 2. Common understanding (why do we consider it important to take uncertainties into account) and aspects on which we disagree (how far should scientists go in communication?); 3. Documents that are considered important by all participants; 4. Do's and don'ts in dealing with uncertainties and communicating about uncertainties (e.g. know your audience, check how your figures are interpreted); 5. Recommendations for further actions (e.g. need for a platform to exchange experiences). The CFR is meant to help researchers in climate adaptation to work together and communicate together on climate change (better interaction between disciplines). It is also meant to help researchers to explain to others (e.g. decision makers) why and when researchers agree and when and why they disagree

  3. Insights from socio-hydrology modelling on dealing with flood risk - Roles of collective memory, risk-taking attitude and trust

    The risk coping culture of a community plays a major role in the development of urban floodplains. In this paper we analyse, in a conceptual way, the interplay of community risk coping culture, flooding damage and economic growth. We particularly focus on three aspects: (i) collective memory, i.e., the capacity of the community to keep risk awareness high; (ii) risk-taking attitude, i.e., the amount of risk the community is collectively willing to be exposed to; and (iii) trust of the community in risk reduction measures. To this end, we use a dynamic model that represents the feedback between the hydrological and social system components. Model results indicate that, on the one hand, by under perceiving the risk of flooding (because of short collective memory and too much trust in flood protection structures) in combination with a high risk-taking attitude, community development is severely limited because of high damages caused by flooding. On the other hand, overestimation of risk (long memory and lack of trust in flood protection structures) leads to lost economic opportunities and recession. There are many scenarios of favourable development resulting from a trade-off between collective memory and trust in risk reduction measures combined with a low to moderate risk-taking attitude. Interestingly, the model gives rise to situations in which the development of the community in the floodplain is path dependent, i.e., the history of flooding may lead to community growth or recession.

    The risk coping culture of a community plays a major role in decision making in urban flood plains. While flood awareness is not necessarily linked to being prepared to face flooding at an individual level, the connection at the community level seems to be stronger through creating policy and initiating protection works. In this work we analyse, in a conceptual way, the interplay of community risk coping culture, flooding damage and economic growth. We particularly focus on three aspects: (i) collective memory, i.e., the capacity of the community to keep the awareness of flooding high; (ii) risk-taking attitude, i.e., the amount of risk a community is collectively willing to expose themselves to; and (iii) trust of people in risk protection measures. We use a dynamic model that represents the feedbacks between the hydrological and social system components. The model results indicate that, on one hand, by under perceiving the risk of flooding (because of short collective memory and too much trust in flood protection structures) in combination with a high risk-attitude, community survival is severely limited because of destruction caused by flooding. On the other hand, high perceived risk (long memory and lack of trust in flood protection structures) relative to the actual risk leads to lost economic opportunities and recession. There are many optimal scenarios for survival and economic growth, but greater certainty of survival plus economic growth can be achieved by ensuring community has accurate risk perception (memory neither too long nor too short and trust in flood protection neither too great nor too low) combined with a low to moderate risk-taking attitude. Interestingly, the model gives rise to situations in which the development of the community in the floodplain is path dependent, i.e., the history of flooding may lead to its growth or recession.

    Cost-effectiveness analyses (CEAs) of behavioral interventions typically use physical outcome criteria. However, any progress in cognitive antecedents of behavior change may be seen as a beneficial outcome of an intervention. The aim of this study is to explore the feasibility and validity of incorporating cognitive parameters of behavior change in CEAs. The CEA from a randomized controlled trial on smoking cessation was reanalyzed. First, relevant cognitive antecedents of behavior change in this dataset were identified. Then, transition probabilities between combined states of smoking and cognitions at 6 weeks and corresponding 6 months smoking status were obtained from the dataset. These rates were extrapolated to the period from 6 to 12 months in a decision analytic model. Simulated results were compared with the 12 months' observed cost-effectiveness results. Self-efficacy was the strongest time-varying predictor of smoking cessation. Twelve months' observed CEA results for the multiple tailoring intervention versus usual care showed € 3188 had to be paid for each additional quitter versus € 10,600 in the simulated model. The simulated CEA showed largely similar but somewhat more conservative results. Using self-efficacy to enhance the estimation of the true behavioral outcome seems a feasible and valid way to estimate future cost-effectiveness. PMID:25448460

  6. The new deal at the top.

    Doz, Yves L; Kosonen, Mikko

    2007-06-01

    What makes a company strategically agile--able to alter its strategies and business models rapidly in response to major changes in its market space, and to do so repeatedly without major trauma? Three years of in-depth case research on a dozen large companies worldwide showed the authors that one key factor is a new leadership model at the top. Senior executives at agile companies assume collective rather than individual responsibility for results. They build interdependencies among units and divisions, motivating themselves to engage with one another, and carefully manage their dealings to promote collaboration that is frequent, intense, informal, open, and focused on shared issues and the long term. Challenges to conventional thinking are encouraged. This is the new deal, and it's not easy to strike, because it requires executives to act in ways that are far from comfortable. After all, the corporate ladder at most firms favors independent types with a deep need for power and autonomy. At executive meetings, disagreement is suppressed or expressed passive-aggressively, eroding any real sense of belonging to a team. Switching to the new deal almost always requires a huge shift in the company's culture, values, and norms of interaction. The authors describe three approaches to making the shift: Executives can be given formal responsibility not for a business unit but for different stages in the company's value chain. This worked well for SAP, which has a relatively focused business portfolio. When a company's portfolio is less uniform, like Nokia's, business and functional units can be organized to crisscross on a matrix. And when a company is widely diverse, like easyGroup, it can emphasize the learning opportunities that units with common business models may share. PMID:17580652

    Recent changes in policies by insurance companies with respect to mandating home sleep apnea testing rather than in-laboratory studies have a large impact on the financial viability of clinical sleep centers. Coping with this disruptive change requires forward planning. First, it is important to be well positioned with respect to facilities so that these can be quickly downsized to control costs. There is also a need to develop, in advance, an accredited home sleep study program so that centers can respond to the rapidly changing environment. Following the change there is a need to control costs by rapidly downsizing the technology workforce. Technologists can be retrained for other essential roles. Centralizing the precertification process with knowledgeable, well-trained staff and a robust auditing process is an essential component. The approach taken at the University of Pennsylvania to this change is described as is how one can ensure continued financial viability of a comprehensive sleep center program in a major academic medical center.

  10. Dealing with the Biological Challenge

    NASA Astrophysics Data System (ADS)

    Schultz, Emeric

    1996-05-01

    The bio-technological revolution presents a real challenge to the chemical education community. This challenge is two-fold: 1) the necessity of teaching students the underlying chemical principles and other skills necessary for sucess in the expanding biotechnological workplace and 2) ensuring and enhancing respect from the biological community for the first two years of the chemistry curriculum. In the opinion of the author, we are not doing a particularly good job of meeting this challenge, although progress is being made. As the "doing" of chemistry becomes easier for biologists, there is the real danger that the knowledge of a significant portion of the underlying chemistry will increasingly be viewed as less valuable, and perhaps even superfluous. The three "Trojan Horses" are: synthetic, analytical, and "process" kits; instrumentation coupled with computer "interpretation"; and molecular modeling. The author believes that in order to address the biological challenge head on, we should give serious consideration to the following: 1) reversing the "learning arrow"; 2) embedding molecular and other modeling; 3) incorporating instrumental analysis and chemistry-by-kit. Reversing the learning arrow approaches the chemistry curriculum by starting with large biomolecules first and working toward smaller fundamental units. The author believes that this approach and a more proactive stance on establishing what is in the domain of chemistry is the means by which the biological challenge, spawned by the bio-technological revolution, can most forcefully be addressed.

  11. A Logical Framework to Deal with Variability

    NASA Astrophysics Data System (ADS)

    Asirelli, Patrizia; Ter Beek, Maurice H.; Fantechi, Alessandro; Gnesi, Stefania

    We present a logical framework that is able to deal with variability in product family descriptions. The temporal logic MHML is based on the classical Hennessy-Milner logic with Until and we interpret it over Modal Transition Systems (MTSs). MTSs extend the classical notion of Labelled Transition Systems by distinguishing possible (may) and required (must) transitions: these two types of transitions are useful to describe variability in behavioural descriptions of product families. This leads to a novel deontic interpretation of the classical modal and temporal operators, which allows the expression of both constraints over the products of a family and constraints over their behaviour in a single logical framework. Finally, we sketch model-checking algorithms to verify MHML formulae as well as a way to derive correct products from a product family description.

    The small fraction of asteroids with Earth-crossing or Earth-approaching orbits is of special interest to us because many will eventually impact our planet. The time-averaged impact flux as a function of projectile energy can be derived from lunar-cratering statistics, although we have little information on the possible variability of this flux over time. Alternatively, we can use current observations of near-Earth asteroids (NEAs) to derive the size distribution and flux of impactors. The effects of impacts of various energies can be modeled, using data from historic impacts (such as the K/T impactor 65 m.y. ago) and the observed 1994 bombardment of Jupiter by fragments of Comet Shoemaker-Levy 9. Such models confirm that the terrestrial biosphere is highly vulnerable to severe perturbation from impacts, so that even such a small event as the K/T impact (by a projectile 10-15 km in diameter) can lead to a mass extinction. Combining the impact flux with estimates of environmental and ecological effects reveals that the greatest contemporary hazard is associated with impactors near 1,000,000 MT energy. The current impact hazard is significant relative to other natural hazards, and arguments can be developed to illuminate a variety of public-policy issues. These include the relative risk of different impact scenarios and the associated costs and probabilities of success of countermeasures. It is generally agreed that the first step is to survey and catalog the larger NEAs. To that end, we review the status of the Spaceguard Survey, which has already discovered more than half of the NEAs larger than 1-km diameter, out of a total population estimated to be between 1000 and 1200. We compare the efficiency of survey approaches and consider the challenges of international coordination and the problems and opportunities associated with communicating the results with the press and the public. It is also important to reflect on how the impact hazard might be dealt with by

    Conoco (Houston), the oil and gas subsidiary of DuPont, has backed out of a deal to develop offshore oil fields for Iran as a result of a week of intense pressure from the Clinton Administration. Under the agreement, Conoco Iran, a Netherlands-based affiliate, would have developed two oil fields in the Persian Gulf. The deal, valued at $1 billion, would have been the first between Iran and a U.S. company since Washington severed relations with Teheran in 1980. Conoco says it operated within the law and with the knowledge of the U.S. government in the three years the deal was being negotiated. President Clinton announced an executive order barring such deals last Tuesday, after Conoco executives informed the Administration that the deal would be abandoned if an order was issued.

    Romero, Vicente Jose

    2011-11-01

    This report explores some important considerations in devising a practical and consistent framework and methodology for utilizing experiments and experimental data to support modeling and prediction. A pragmatic and versatile 'Real Space' approach is outlined for confronting experimental and modeling bias and uncertainty to mitigate risk in modeling and prediction. The elements of experiment design and data analysis, data conditioning, model conditioning, model validation, hierarchical modeling, and extrapolative prediction under uncertainty are examined. An appreciation can be gained for the constraints and difficulties at play in devising a viable end-to-end methodology. Rationale is given for the various choices underlying the Real Space end-to-end approach. The approach adopts and refines some elements and constructs from the literature and adds pivotal new elements and constructs. Crucially, the approach reflects a pragmatism and versatility derived from working many industrial-scale problems involving complex physics and constitutive models, steady-state and time-varying nonlinear behavior and boundary conditions, and various types of uncertainty in experiments and models. The framework benefits from a broad exposure to integrated experimental and modeling activities in the areas of heat transfer, solid and structural mechanics, irradiated electronics, and combustion in fluids and solids.

  4. When to walk away from a deal.

    Cullinan, Geoffrey; Le Roux, Jean-Marc; Weddigen, Rolf-Magnus

    2004-04-01

    Deal making is glamorous; due diligence is not. That simple statement goes a long way toward explaining why so many companies have made so many acquisitions that have produced so little value. The momentum of a transaction is hard to resist once senior management has the target in its sights. Companies contract "deal fever," and due diligence all too often becomes an exercise in verifying the target's financial statements rather than conducting a fair analysis of the deal's strategic logic and the acquirer's ability to realize value from it. Seldom does the process lead managers to kill potential acquisitions, even when the deals are deeply flawed. In a recent Bain & Company survey of 250 international executives with M&A responsibilities, only 30% of them were satisfied with the rigor of their due diligence. And fully a third admitted they hadn't walked away from deals they had nagging doubts about. In this article, the authors, all Bain consultants, emphasize the importance of comprehensive due diligence practices and suggest ways companies can improve their capabilities in this area. They provide rich real-world examples of companies that have had varying levels of success with their due diligence processes, including Safeway, Odeon, American Sea-foods, and Kellogg's. Effective due diligence requires answering four basic questions: What are we really buying? What is the target's stand-alone value? Where are the synergies--and the skeletons? And what's our walk-away price? Each of these questions will prompt an even deeper level of querying that puts the broader, strategic rationale for acquisitions under a microscope. Successful acquirers pay close heed to the results of such in-depth investigations and analyses--to the extent that they are prepared to walk away from a deal, even in the very late stages of negotiations.

    NASA Technical Reports Server (NTRS)

    Armellin, Roberto; Di Lizia, Pierluigi; Zanetti, Renato

    2015-01-01

    A method to deal with uncertainties in initial orbit determination (IOD) is presented. This is based on the use of Taylor differential algebra (DA) to nonlinearly map the observation uncertainties from the observation space to the state space. When a minimum set of observations is available DA is used to expand the solution of the IOD problem in Taylor series with respect to measurement errors. When more observations are available high order inversion tools are exploited to obtain full state pseudo-observations at a common epoch. The mean and covariance of these pseudo-observations are nonlinearly computed by evaluating the expectation of high order Taylor polynomials. Finally, a linear scheme is employed to update the current knowledge of the orbit. Angles-only observations are considered and simplified Keplerian dynamics adopted to ease the explanation. Three test cases of orbit determination of artificial satellites in different orbital regimes are presented to discuss the feature and performances of the proposed methodology.

    PubMed

    Gravenhorst, J Bennebroek; Engberts, D P

    2002-11-01

    During the last century the patient-doctor relationship has changed considerably. This change becomes particularly visible when the relationship between the two parties is disturbed. this is usually caused by patient dissatisfaction with the doctor or other workers in the medical profession. Handling dissatisfaction should be part of a doctor's professional skills. The most important advice in dealing with dissatisfaction is to react fast. A doctor should have the good sense to raise the issue for discussion as soon as he/she senses signs of dissatisfaction. If this is not possible and the issue results in a written complaint, the plaintiff can lodge a complaint within the framework of a special law. The complaint is then handled by a complaints committee. Over the past years, mediation has been used increasingly. This procedure has a low threshold, works fast and often results in reconciliation of both parties. If the intervention of a complaints committee is not desired and mediation is not realistic or rejected, the case sometimes progresses to the disciplinary board or civil judge. This often leads to protracted procedures and is stressful to both parties. It is important to prevent these kinds of procedures as much as possible by reacting swiftly and appropriately to signs of dissatisfaction. PMID:12448961

  15. Dealing with future risks in the Netherlands.

    2013-09-01

    The national security strategy is the Dutch government's instrument for multihazard risk management and is intended to contribute to the prevention of societal disruption as a consequence of a (future) disaster or crisis in the Netherlands. It considers the likelihood that a certain incident will occur, the impact if it should occur, and what can be done to prevent the occurrence and/or reduce the impact. In other words, "which threats is the Netherlands faced with, how serious are they, and what can be done to mitigate the consequences?" By annually assessing the likelihood and impact of different scenarios, the government is able to continually improve its overview of risks and to determine priorities regarding the allocation of resources for the prevention of, preparation for, and response to threats. At the start of the annual cycle of the implementation of the national security strategy, possible scenarios are identified. These scenarios are then drawn up and assessed by the Network of Analysts for National Security, resulting in the national risk assessment (NRA). On the basis of this risk assessment, a capabilities analysis is performed. This capabilities analysis assesses whether the country (government, private sector, and civilians) has sufficient capabilities (people, material, knowledge, skills, and procedures) at its disposal to adequately deal with the threat, and it considers which capabilities should be strengthened or developed. Finally, a report is prepared for the council of ministers. On the basis of this report, the cabinet decides which capabilities will be strengthened. PMID:23971823

  16. Deal or No Deal: using games to improve student learning, retention and decision-making

    Student understanding and retention can be enhanced and improved by providing alternative learning activities and environments. Education theory recognizes the value of incorporating alternative activities (games, exercises and simulations) to stimulate student interest in the educational environment, enhance transfer of knowledge and improve learned retention with meaningful repetition. In this case study, we investigate using an online version of the television game show, 'Deal or No Deal', to enhance student understanding and retention by playing the game to learn expected value in an introductory statistics course, and to foster development of critical thinking skills necessary to succeed in the modern business environment. Enhancing the thinking process of problem solving using repetitive games should also improve a student's ability to follow non-mathematical problem-solving processes, which should improve the overall ability to process information and make logical decisions. Learning and retention are measured to evaluate the success of the students' performance.

  18. A backtracking algorithm that deals with particle filter degeneracy

    NASA Astrophysics Data System (ADS)

    Baarsma, Rein; Schmitz, Oliver; Karssenberg, Derek

    2016-04-01

    Particle filters are an excellent way to deal with stochastic models incorporating Bayesian data assimilation. While they are computationally demanding, the particle filter has no problem with nonlinearity and it accepts non-Gaussian observational data. In the geoscientific field it is this computational demand that creates a problem, since dynamic grid-based models are often already quite computationally demanding. As such it is of the utmost importance to keep the amount of samples in the filter as small as possible. Small sample populations often lead to filter degeneracy however, especially in models with high stochastic forcing. Filter degeneracy renders the sample population useless, as the population is no longer statistically informative. We have created an algorithm in an existing data assimilation framework that reacts to and deals with filter degeneracy based on Spiller et al. [2008]. During the Bayesian updating step of the standard particle filter, the algorithm tests the sample population for filter degeneracy. If filter degeneracy has occurred, the algorithm resets to the last time the filter did work correctly and recalculates the failed timespan of the filter with an increased sample population. The sample population is then reduced to its original size and the particle filter continues as normal. This algorithm was created in the PCRaster Python framework, an open source tool that enables spatio-temporal forward modelling in Python [Karssenberg et al., 2010] . The framework already contains several data assimilation algorithms, including a standard particle filter and a Kalman filter. The backtracking particle filter algorithm has been added to the framework, which will make it easy to implement in other research. The performance of the backtracking particle filter is tested against a standard particle filter using two models. The first is a simple nonlinear point model, and the second is a more complex geophysical model. The main testing

  19. Dealing with the Asteroid Impact Hazard

    NASA Technical Reports Server (NTRS)

    Morrison, David

    2001-01-01

    The small fraction of the asteroids with Earth-crossing or Earth-approaching orbits is of special interest to us because many will eventually impact our planet. The time-averaged impact flux as a function of projectile energy can be derived from lunar cratering statistics, although we have little information on the possible variability of this flux over time. The effects of impacts of various energies can be modeled, using data from historic impacts (such as the KT impactor 65 million years ago), nuclear explosive testing, and the observed 1994 bombardment of Jupiter by fragments of comet Shoemaker-Levy 9. It is of particular interest to find from such models that the terrestrial environment is highly vulnerable to perturbation from impacts, so that even such a small event as the KT impact (by a projectile roughly 15 km in diameter) can lead to a mass extinction. Combining the impact flux with estimates of environmental and ecological effects reveals that the greatest contemporary hazard is associated with impactors near one million megatons energy. The current impact hazard is significant relative to other natural hazards, and arguments can be developed to illuminate a variety of public policy issues. These include the relative risk of different impact scenarios and the associated costs and probability of success of countermeasures. It is generally agreed that the first step is to survey and catalogue the thousand-or-so Near Earth Asteroids (NEAs), and we review the status of the Spaceguard NEA Survey. We compare the efficiency of various ground and space-based approaches and consider the challenges of international coordination and the problems and opportunities associated with communicating the results with the press and the public. It is also important to reflect on how the impact hazard might be dealt with by both national governments and international decision-making bodies, and to anticipate ways of mitigating the danger if a NEA were located on an apparent

  20. Dealing with teen-age pregnancy.

    PubMed

    Dempsey, P L

    1991-01-01

    The author finds that teenage pregnancy is more complicated than access to contraception or abortion. At risk teenagers are not identifiable, only at risk factors such as isolation, lack of perception of future opportunities, lack of self esteem, lack of self worth, poor performance in school, poor role models or lack of role models at home or in the community. There is indictment of parents who are just as much in need. The focus on teen pregnancy as one dimensional belies the reality that health, family, work, social and cultural experience affect people's decisions and sexual behavior. The recommendation is for a holistic approach, regardless of race, ethnicity, or socioeconomic background. Adolescents need education and jobs as well as preventive health, body image, and nutrition in conjunction with contraceptives. Where success is defined by motherhood or fatherhood, birth control pills sit in drawers at home. Teenagers need to be convinced that there is some benefit in being connected to mainstream society. Support services need to help teenagers answer the question of what's in it for me? Why? Teenagers need assistance in attaining educational success, job success, the ability to handle anger, and leadership opportunities. A holistic approach is not only realistic but also is the most practical with the longest term benefit. With resources for teen pregnancy superseded by the problems of AIDs and crack gangs, there is a constantly changing political agenda for resource allocation. In fact, teenage pregnancy is reflective of social ills in an urban society simultaneous with drug abuse, school dropouts, juvenile crime and gang activity. The common denominator is that teens all need good educational opportunities, good health, and good housing. Parent involvement is needed, and it is presumptuous to believe that a couple of hours of contact a week can change lives. Parents need respect and understanding for their important role; they need information and a role

  1. Dealing with uncertainty in water scarcity footprints

    Scherer, Laura; Pfister, Stephan

    2016-05-01

    Water scarcity adversely affects ecosystems, human well-being and the economy. It can be described by water scarcity indices (WSIs) which we calculated globally for the decades 1981–1990 and 2001–2010. Based on a model ensemble, we calculated the WSI for both decades including uncertainties. While there is a slight tendency of increased water scarcity in 2001–2010, the likelihood of the increase is rather low (53%). Climate change played only a minor role, but increased water consumption is more decisive. In the last decade, a large share of the global population already lived under highly water scarce conditions with a global average monthly WSI of 0.51 (on a scale from 0 to 1). Considering that globally there are enough water resources to satisfy all our needs, this highlights the need for regional optimization of water consumption. In addition, crop choices within a food group can help reduce humanity’s water scarcity footprint without reducing its nutritional value.

    1993-10-01

    The effect of crack dealing on emotionally disturbed adolescents in two African-American inner-city communities is examined and illustrated by case examples. Crack dealing was most often found to have dynamics and consequences separate from those of crack use. These include post-traumatic stress disorder and other significant emotional disturbances arising from the violence associated with crack dealing, and the shaping of adolescent identity by the associated culture of violence and guns. Implications for school drug abuse education are explored. PMID:8267095

  5. Strategies for dealing with fraud in clinical trials.

    PubMed

    Herson, Jay

    2016-02-01

    Research misconduct and fraud in clinical research is an increasing problem facing the scientific community. This problem is expected to increase due to discoveries in central statistical monitoring and with the increase in first-time clinical trial investigators in the increasingly global reach of oncology clinical trials. This paper explores the most common forms of fraud in clinical trials in order to develop offensive and defensive strategies to deal with fraud. The offensive strategies are used when fraud is detected during a trial and the defensive strategies are those design strategies that seek to minimize or eliminate the effect of fraud. This leads to a proposed fraud recovery plan (FRP) that would be specified before the start of a clinical trial and would indicate actions to be taken upon detecting fraud of different types. Statistical/regulatory issues related to fraud include: dropping all patients from a site that committed fraud, or just the fraudulent data (perhaps replacing the latter through imputation); the role of intent-to-treat analysis; effect on a planned interim analysis; effect on stratified analyses and model adjustment when fraud is detected in covariates; effect on trial-wide randomization, etc. The details of a typical defensive strategy are also presented. It is concluded that it is best to follow a defensive strategy and to have an FRP in place to follow if fraud is detected during the trial. PMID:26194810

  10. Dealing with typical values via Atanassov's intuitionistic fuzzy sets

    NASA Astrophysics Data System (ADS)

    Szmidt, Eulalia; Kacprzyk, Janusz

    2010-07-01

    This paper is an improved and extended version of our previous work2 on typicality in terms of Atanassov's intuitionistic fuzzy sets (to be called A-IFSs, for short)3. We follow the line of reasoning known from psychological and cognitive sciences, in particular from linguistic experiments, and verify how those results work in the case of classification - a typical problem in computer science, decision sciences, etc. Our considerations concentrate on a typical example discussed in cognitive sciences - we investigate to which extent a linguistic representation in a psychological space (we start from nominal data - names are assigned to objects as labels) succeeds in predicting categories via A-IFSs. First, we consider a model of categories with a geometrical centroid model in which the similarity is defined in terms of a distance to centroids. Next, we verify if the extreme ideals, which are important in cognitive processes when categories are learnt in the presence of the alternative (contrast) category, give comparative results. Finally, we discuss if the 'reachable extreme ideals' and 'dominating frequency centres' give comparative results. We show that A-IFSs make it possible to reflect a positive and negative information via the concept of membership and non-membership. Although the paper presents ongoing research, the results obtained are promising and point out the usefulness and strength of A-IFSs as a tool to account for more aspects of vague data and information. Based on 'On Some Typical Values for A-IFS', by E. Szmidt and J. Kacprzyk which appeared in the Proceedings of the 4th International IEEE Conference on Intelligent Systems IS'08, pp. 13-2-13-7. There is currently a discussion on the appropriateness of the name IFS introduced by Dubois et al. (2005), and also Atanassov's (2005) response. This is, however, beyond the scope of this paper which will not be dealing with this issue.

  11. REDD+ emissions estimation and reporting: dealing with uncertainty

    NASA Astrophysics Data System (ADS)

    Pelletier, Johanne; Martin, Davy; Potvin, Catherine

    2013-09-01

    The United Nations Framework Convention on Climate Change (UNFCCC) defined the technical and financial modalities of policy approaches and incentives to reduce emissions from deforestation and forest degradation in developing countries (REDD+). Substantial technical challenges hinder precise and accurate estimation of forest-related emissions and removals, as well as the setting and assessment of reference levels. These challenges could limit country participation in REDD+, especially if REDD+ emission reductions were to meet quality standards required to serve as compliance grade offsets for developed countries’ emissions. Using Panama as a case study, we tested the matrix approach proposed by Bucki et al (2012 Environ. Res. Lett. 7 024005) to perform sensitivity and uncertainty analysis distinguishing between ‘modelling sources’ of uncertainty, which refers to model-specific parameters and assumptions, and ‘recurring sources’ of uncertainty, which refers to random and systematic errors in emission factors and activity data. The sensitivity analysis estimated differences in the resulting fluxes ranging from 4.2% to 262.2% of the reference emission level. The classification of fallows and the carbon stock increment or carbon accumulation of intact forest lands were the two key parameters showing the largest sensitivity. The highest error propagated using Monte Carlo simulations was caused by modelling sources of uncertainty, which calls for special attention to ensure consistency in REDD+ reporting which is essential for securing environmental integrity. Due to the role of these modelling sources of uncertainty, the adoption of strict rules for estimation and reporting would favour comparability of emission reductions between countries. We believe that a reduction of the bias in emission factors will arise, among other things, from a globally concerted effort to improve allometric equations for tropical forests.

    2012-12-01

    The methods of lean manufacturing primarily designed for businesses dealing with serial production, are also used in other types of production. However the concept of lean production was not designed for these types of businesses, they are utilized only partially. Paper focuses on applying methods of lean concept in companies which are dealing with mass production and their options of exchange for other methods in the event of disagreement. Basis of the article is a list of lean methods with its description and its utilization in practice. The questionnaire was utilized to identify information from the practice. Based on this survey were identified the critical methods that are no longer appropriate for companies dealing with mass production. However, there are alternative methods of describing the problem. It is possible to say that companies are trying to get closer to their goal by modification of the basic concepts. And the concept of Lean Enterprise serves as a standard.

  13. Deal or no deal: can incentives encourage widespread adoption of intelligent speed adaptation devices?

    PubMed

    Chorlton, Kathryn; Hess, Stephane; Jamson, Samantha; Wardman, Mark

    2012-09-01

    Given the burden of injury, economic, environmental and social consequences associated with speeding, reducing road traffic speed remains a major priority. Intelligent speed adaptation (ISA) is a promising but controversial new in-vehicle system that provides drivers with support on the speed-control task. In order to model potential system uptake, this paper explores drivers' preferences for two different types of ISA given a number of alternative fiscal incentives and non-fiscal measures, using a stated preference approach. As would be expected with such a contentious issue, the analysis revealed the presence of significant variations in sensitivities and preferences in the sample. While a non-negligible part of the sample population has such strong opposition to ISA that no reasonable discounts or incentives would lead to them buying or accepting such a system, there is also a large part of the population that, if given the right incentives, would be willing or even keen to equip their vehicle with an ISA device.

    PubMed Central

    Mathieu, Amélie; Cournède, Paul-Henry; Barthélémy, Daniel; de Reffye, Philippe

    2008-01-01

    Background and Aims To model plasticity of plants in their environment, a new version of the functional–structural model GREENLAB has been developed with full interactions between architecture and functioning. Emergent properties of this model were revealed by simulations, in particular the automatic generation of rhythms in plant development. Such behaviour can be observed in natural phenomena such as the appearance of fruit (cucumber or capsicum plants, for example) or branch formation in trees. Methods In the model, a single variable, the source–sink ratio controls different events in plant architecture. In particular, the number of fruits and branch formation are determined as increasing functions of this ratio. For some sets of well-chosen parameters of the model, the dynamical evolution of the ratio during plant growth generates rhythms. Key Results and Conclusions Cyclic patterns in branch formation or fruit appearance emerge without being forced by the model. The model is based on the theory of discrete dynamical systems. The mathematical formalism helps us to explain rhythm generation and to control the behaviour of the system. Rhythms can appear during both the exponential and stabilized phases of growth, but the causes are different as shown by an analytical study of the system. Simulated plant behaviours are very close to those observed on real plants. With a small number of parameters, the model gives very interesting results from a qualitative point of view. It will soon be subjected to experimental data to estimate the model parameters. PMID:17715304

    Following the global raise in demand for food and biofuel production, transnational companies are acquiring large scale agricultural land in developing countries such as Ethiopia. Considering land as one of the factors to be outsourced for development, the government of Ethiopia is supplying millions of hectares of land to transnational companies in the form of longterm lease. Many of the companies which engage in large scale land acquisition are of Indian, Chinese, Ethiopian diaspora, German, Malaysian, Italian, British, Dutch, Turkish, and Saudi-Arabian origin. The boom in the acquisition of farm land in the country has sparked an all-rounded debate among civil society groups, international institutions, nongovernmental organizations and independent development experts. The common reflections concerning the land deals in Ethiopia and elsewhere contain much rhetoric and hype which lack analysis of the real situation "on the ground" giving different connotations such as 'land grabbing', 'agricultural outsourcing', 'neo-colonialism', 'agrarian colonialism', and 'land underdevelopment'. However, deforestation, soil degradation, marginalization of local indigenous communities, and minimally unfair gains from investment by the host country are among the real points of concern arising out of the long term land lease contracts. Scientific evidence is lacking concerning the pragmatic impacts of large scale agricultural land acquisitions by transnational companies upon the natural environment (forest and land), local peoples' livelihood, and the contacting parties (the host country and the companies). The major objective of this study is to investigate the impacts in the context of Ethiopia, orienting to reinvent win-win land use models which constitute sustainable land use, local peoples' livelihood and the company-host country interests. To achieve this overall objective, the study employs a number of methods and methodologies constituting both qualitative and

    Integrity has been an important matter of concern for the scientific community as it affects the basis of its activities. Most countries having a significant scientific activity have dealt with this problem by different means, including drafting specific legal or soft law regulations and the appointment of stable or ad hoc committees that take care of these questions. This has also been the case in Spain. After the period of transition between dictatorship to a democratic regime, and, particularly, after the entrance in the European Union, scientific activity has increased in the country. As it could be expected, problems of misconduct have appeared and different institutions have been dealing with these matters. One of the best examples is that of Consejo Superior de Investigaciones Cientificas (CSIC), the largest institution devoted to scientific research belonging to the Spanish Government. The experience of the CSIC’s Ethics Committee in dealing with conflicts related to scientific practices is discussed here. PMID:24121929

  4. Deal making 2.0: a guide to complex negotiations.

    PubMed

    Lax, David A; Sebenius, James K

    2012-11-01

    Most big deals--megamergers, major sales, infrastructure projects--are built on a series of smaller ones. Each component deal presents a tactical challenge, but sequencing the parts in a way that achieves the target outcome is a strategic challenge that can unfold over months or years. This process, which the authors call a negotiation campaign, must generally be conducted on several fronts, each involving multiple parties. A multifront campaign can be much more effective than direct negotiation. After failed talks between Longshoremen and the Pacific Maritime Association--a group of shippers and port operators--the PMA's president turned away from the bargaining table and embarked on a campaign to align member-firms, the business community, the U.S. government, and the public around his target outcome: the deployment of new information technologies to help unclog busy ports. The result was an agreement that was ultimately mutually beneficial. Designing and executing a negotiation campaign involves identifying the relevant parties, grouping them into fronts according to shared interests, determining whether to combine fronts (if, for instance, doing so would unite your allies), and deciding which fronts to approach early on and which to engage only after you've made progress elsewhere. The deal between the PMA and the Longshoremen involved high stakes, but many small-scale deals--such as gaining approval for a new product--also play out on multiple fronts. Going straight to a key decision maker often makes sense, but in many cases a multifront campaign is the only way. PMID:23156000

    2009-09-01

    The industrial adoption of concepts such as open innovation brings new legitimacy to activities technology-transfer professionals have conducted for over 20 years. This movement highlights the need for an increased understanding of the valuation of intellectual property (IP) and technology-transfer deals. Valuation, though a centerpiece of corporate finance, is more challenging when applied to the inherent uncertainty surrounding innovation. Technology-transfer professionals are often overwhelmed by the complexity and data requirements of valuation techniques and skeptical of their applicability to and utility for technology transfer. The market longs for an approach which bridges the gap between valuation fundamentals and technology-transfer realities. This paper presents the foundations of a simple, flexible, precise/accurate, and useful framework for considering the valuation of technology-transfer deals. The approach is predicated on a 12-factor model—a 3×4 value matrix predicated on categories of economic, societal, and strategic value. Each of these three categories consists of three core subcategories followed by a fourth "other" category to facilitate inevitable special considerations. This 12-factor value matrix provides a framework for harvesting data during deals and for the application of best-of-breed valuation techniques which can be employed on a per-factor basis. Future work will include framework implementation within a database platform.

    2013-09-01

    The more death is studied, the more it remains a mystery. Dealing with death is no easy matter and for that reason it is so frightening. All the fears of human beings are fundamentally related to the fear of death. This is because it is a mystery about which we know little or nothing, although it is natural to die. In view of this, religions give this topic a primary focus. Therefore, in this article an attempt is made to deal with the taboo surrounding death and reflect on issues associated with it. These themes are present in people's lives, especially when they have the experience of losing someone in their family or circle of friends. Among these subjects, the aspects of the Anointing of the Sick, the Funeral Mass, the Seventh Day Mass and the tradition of praying for the dead are all touched upon. These are all themes that help to deal with the taboo of death or losing a loved one. PMID:23989577

    The assessment of greenhouse gases emitted to and removed from the atmosphere is high on the international political and scientific agendas. Growing international concern and cooperation regarding the climate change problem have increased the need for policy-oriented solutions to the issue of uncertainty in, and related to, inventories of greenhouse gas (GHG) emissions. The approaches to addressing uncertainty discussed in this Special Issue reflect attempts to improve national inventories, not only for their own sake but also from a wider, systems analytical perspective-a perspective that seeks to strengthen the usefulness of national inventories under a compliance and/or global monitoring and reporting framework. These approaches demonstrate the benefits of including inventory uncertainty in policy analyses. The authors of the contributed papers show that considering uncertainty helps avoid situations that can, for example, create a false sense of certainty or lead to invalid views of subsystems. This may eventually prevent related errors from showing up in analyses. However, considering uncertainty does not come for free. Proper treatment of uncertainty is costly and demanding because it forces us to make the step from 'simple to complex' and only then to discuss potential simplifications. Finally, comprehensive treatment of uncertainty does not offer policymakers quick and easy solutions. The authors of the papers in this Special Issue do, however, agree that uncertainty analysis must be a key component of national GHG inventory analysis. Uncertainty analysis helps to provide a greater understanding and better science helps us to reduce and deal with uncertainty. By recognizing the importance of identifying and quantifying uncertainties, great strides can be made in ongoing discussions regarding GHG inventories and accounting for climate change. The 17 papers in this Special Issue deal with many aspects of analyzing and dealing with uncertainty in emissions

    1997-09-01

    Most utility industry engineers are experiencing significant job security anxiety brought on by unprecedented industry changes such as impending industry re-regulation, diminished domestic new generation projects, utility restructuring, and re-engineering. Observations of leading utilities, A/Es, and major manufacturers show that many challenging opportunities for engineers are emerging from these changes but these jobs often require early planning and investments in broadened skills, improved business perspective and competitive flexibility to capture and maintain them. There is a growing corporate expectation that engineers can become comfortable with competition, business accountabilities, frequent job change, offshore assignments, and lifelong learning. This article is written to help utility industry engineers, their managers and executives better understand these changes and to hopefully create a broader acceptance of a New Deal. This New Deal focuses on visioning industry change impacts on future job content, co-planning and co-investments in skill and business perspective broadening, early identification and winning of challenging opportunities and, most importantly, strong personal commitments to staying on top of the new utility game which is competition, competition, and competition.

  12. Energy Security: From Deal Killers to Game Changers

    Five energy security ``deal killers" are identified: 1) Global warming and CO2 emissions from fossil fuel combustion; 2) Intermittent energy sources (wind, solar) and the presence and stability of the grid; 3) Penetration of plant defenses to produce transportation fuels from biomass; 4) Mimicking nature: artificial photosynthesis for solar energy to fuels; and 5) Spent fuel from nuclear power reactors. Transformational basic research is required to successfully change the ground rules, to transform these ``deal killers" into ``game changers." T hey are: 1) Offsetting carbon capture and storage costs through enhanced oil recovery and methane generation from high temperature geothermal saline aquifers; 2) Electrical energy storage, through batteries and super-capacitors; 3) Genetic modification of plant cell walls, and catalytic methods for transforming plant sugars into fuels; 4) Separation of solar-induced electrons from holes, and catalysis to produce fuels; and 5) Closing the nuclear fuel cycle. Basic research can revolutionize our approach to carbon-free energy by enhancing nature to achieve energy security.

    2009-01-01

    Background Publication databases in biomedicine (e.g., PubMed, MEDLINE) are growing rapidly in size every year, as are public databases of experimental biological data and annotations derived from the data. Publications often contain evidence that confirm or disprove annotations, such as putative protein functions, however, it is increasingly difficult for biologists to identify and process published evidence due to the volume of papers and the lack of a systematic approach to associate published evidence with experimental data and annotations. Natural Language Processing (NLP) tools can help address the growing divide by providing automatic high-throughput detection of simple terms in publication text. However, NLP tools are not mature enough to identify complex terms, relationships, or events. Results In this paper we present and extend BioDEAL, a community evidence annotation system that introduces a feedback loop into the database-publication cycle to allow scientists to connect data-driven biological concepts to publications. Conclusion BioDEAL may change the way biologists relate published evidence with experimental data. Instead of biologists or research groups searching and managing evidence independently, the community can collectively build and share this knowledge. PMID:19891799

    2009-01-01

    Background and Aims The strong influence of environment and functioning on plant organogenesis has been well documented by botanists but is poorly reproduced in most functional–structural models. In this context, a model of interactions is proposed between plant organogenesis and plant functional mechanisms. Methods The GreenLab model derived from AMAP models was used. Organogenetic rules give the plant architecture, which defines an interconnected network of organs. The plant is considered as a collection of interacting ‘sinks’ that compete for the allocation of photosynthates coming from ‘sources’. A single variable characteristic of the balance between sources and sinks during plant growth controls different events in plant development, such as the number of branches or the fruit load. Key Results Variations in the environmental parameters related to light and density induce changes in plant morphogenesis. Architecture appears as the dynamic result of this balance, and plant plasticity expresses itself very simply at different levels: appearance of branches and reiteration, number of organs, fructification and adaptation of ecophysiological characteristics. Conclusions The modelling framework serves as a tool for theoretical botany to explore the emergence of specific morphological and architectural patterns and can help to understand plant phenotypic plasticity and its strategy in response to environmental changes.

    Neural systems have to function efficiently in the presence of noise, which occurs at all levels of neural information processing. We use a computational model of the insect olfactory system in order to investigate how this system can deal with external and internal noise. We compare our results with previous models of the mammalian olfactory system. We address questions, such as, how can the system suppress noise, or maybe even make use of it? Could noise-induced oscillations and stochastic resonance also exist in the insect olfactory system? Our simulation results indicate a positive role for noise also in the insect olfactory system, but many questions are still open.

    1998-10-01

    Demands by Patients or their Families for treatment thought to be inappropriate by health care providers constitute an important set of moral problems in clinical practice. A variety of approaches to such cases have been described in the literature, including medical futility, standard of care and negotiation. Medical futility fails because it confounds morally distinct cases: demand for an ineffective treatment and demand for an effective treatment that supports a controversial end (e.g., permanent unconsciousness). Medical futility is not necessary in the first case and is harmful in the second. Ineffective treatment falls outside the standard of care, and thus health care workers have no obligation to provide it. Demands for treatment that supports controversial ends are difficult cases best addressed through open communication, negotiation and the use of conflict-resolution techniques. Institutions should ensure that fair and unambiguous procedures for dealing with such cases are laid out in policy statements. PMID:9805031

    2016-08-01

    A method to deal with uncertainties in initial orbit determination (IOD) is presented. This is based on the use of Taylor differential algebra (DA) to nonlinearly map uncertainties from the observation space to the state space. When a minimum set of observations is available, DA is used to expand the solution of the IOD problem in Taylor series with respect to measurement errors. When more observations are available, high order inversion tools are exploited to obtain full state pseudo-observations at a common epoch. The mean and covariance of these pseudo-observations are nonlinearly computed by evaluating the expectation of high order Taylor polynomials. Finally, a linear scheme is employed to update the current knowledge of the orbit. Angles-only observations are considered and simplified Keplerian dynamics adopted to ease the explanation. Three test cases of orbit determination of artificial satellites in different orbital regimes are presented to discuss the feature and performances of the proposed methodology.

    The influence of energy-saving measures on indoor radon concentration has been studied on the basis of a family house made of clinker concrete wall panels containing from 1000 up to 4000 Bq kg(-1) of 226Ra. Thermal retrofitting based on installing external thermal insulation composite system on the building envelope and replacing existing windows by new ones decreased the annual energy need for heating 2.8 times, but also reduced the ventilation rate to values<0.1 h(-1). As a consequence, the 1-y average indoor radon concentration values increased 3.4 times from 337 to 1117 Bq m(-3). The additional risk of lung cancer in the thermally retrofitted house increased to a value that is 125 % higher than before conversion. Methods for dealing with this enhanced risk by increasing the ventilation rate are discussed. Recovery of investments and the energy consequences of increased ventilation are studied in a long-term perspective. PMID:24729563

    This study tests the hypothesis of vulnerability in health and social care professionals dealing with difficult adolescents. This vulnerability appears to be underpinned by an occupational identity crisis that seems to diminish the ability of these professionals to recognize the suffering of these adolescents. A questionnaire was developed and then distributed during a network day bringing together members of various institutions and bodies working with difficult adolescents. Ninety-three professionals responded. Occupational identity weaknesses were identified: inadequate basic training, experiences of solitude, feelings of powerlessness and exposure, inadequate personal and institutional resources. Actors involved express their need for inter-institutional and inter-sectoral network but find it uneasy to implement. Some changes can be recommended to reduce this occupational identity crisis: increased efforts towards continuing training, development of possibilities of reflection within institutions, and more structured partnerships and actions.

    School nurses have an important role in helping students to deal with bullying. However, most of the previously undertaken studies do not have nurses as the subjects, considering their experiences around this theme. This study used a qualitative approach through in-depth interviews with 12 school nurses (SNs). The thematic analysis was employed and supported by NVivo 10 software. Five main themes arose from the analysis: (1) understanding about bullying, (2) how they identified bullying, (3) strategies, (4) support at the workplace, and (5) SNs' role. SNs have a reasonable knowledge about this issue and are capable of helping students through dialogue. However, there is a need to be trained and have more time to be able to give proper help to the students, also using other different strategies. SNs must work more actively on this issue with schools and be supported in terms of staff numbers. PMID:26502929

    Background A growing body of research indicates that physicians suffer high levels of stress, depression and burnout. Related literature has found that physician stress can negatively impact patient care. This study builds upon previous research that found some dying patients experienced ‘iatrogenic suffering’ caused by the way physicians communicated with them regarding terminal diagnoses and palliative treatment. The goal of this research was to explore physicians’ experiences of dealing with patient death in order to understand how such experiences affect them and their communication with patients. Methods This study used qualitative methods to conduct and analyse 10 individual, semistructured interviews with senior physicians from several specialty areas at a large, tertiary care hospital. The resulting themes were validated using member checks and expert review. Results This article presents five essential themes that provide a concise description of the lived experience of patient death for these physicians. Interpretation: These themes indicate that physicians can experience very strong and lasting emotional reactions to some patient deaths, and also that patient death can elicit intense experiences related to professional responsibility and competence. A key finding is the description of a complex process of managing the balance between personal and professional reactions in the face of patient death. The implication is that difficulties negotiating this balance may lead to unintended lapses in compassion and suboptimal outcomes in patient care. PMID:24644159

  6. How to deal with negative surface heat capacities

    NASA Astrophysics Data System (ADS)

    Schneider, W.

    2015-03-01

    Negative surface heat capacities are observed for many liquids, at least in certain temperature regimes. Since thermodynamic stability of a system requires positive heat capacities, it is usually argued that the surface must not be considered as an autonomous system. This, however, is not possible when the energy balance of the surface plays the role of a boundary condition for the field equations, e.g. the heat diffusion equation. A heat pulse supplied to the surface of a liquid and the stretching of a liquid film provide two examples to demonstrate that negative surface heat capacities may lead to unbounded and unconfined growth of the temperature disturbances in the liquid. To deal with the instabilities associated with negative surface heat capacities it is proposed to introduce a surface layer of small, but finite, thickness that is defined solely in terms of macroscopic thermodynamic quantities. By considering the energy balance of the surface layer, which is an open system, it is shown that the isobaric heat capacity of the liquid contained in the surface layer is to be added to the (possibly negative) surface heat capacity to obtain a positive total heat capacity of the surface layer.

    This presentation discusses the experiences of the NASA Dryden Flight Research Center's (DFRC) Western Aeronautical Test Range (WATR) in dealing with the problems encountered while performing post flight data processing using the WATR's data collection/processing system on Chapter 10 files from different Chapter 10 recorders. The transition to Chapter 10 recorders has brought Vvith it an assortment of issues that must be addressed: the ambiguities of language in the Chapter 10 standard, the unrealistic near-term expectations of the Chapter 10 standard, the incompatibility of data products generated from Chapter 10 recorders, and the unavailability of mature Chapter 10 applications. Some of these issues properly belong to the users of Chapter 10 recorders, some to the manufacturers, and some to the flight test community at large. The goal of this presentation is to share the WATR's lesson learned in processing data products from various Chapter 10 recorder vendors. The WATR could benefit greatly in the open forum Vvith lessons learned discussions with other members of the flight test community.

    Dynamical systems often contain oscillatory forces or depend on periodic potentials. Time or space periodicity is reflected in the properties of these systems through a dependence on the parameters of their periodic terms. In this paper we provide a general theoretical framework for dealing with these kinds of systems, regardless of whether they are classical or quantum, stochastic or deterministic, dissipative or nondissipative, linear or nonlinear, etc. In particular, we are able to show that simple symmetry considerations determine, to a large extent, how their properties depend functionally on some of the parameters of the periodic terms. For the sake of illustration, we apply this formalism to find the functional dependence of the expectation value of the momentum of a Bose-Einstein condensate, described by the Gross-Pitaewskii equation, when it is exposed to a sawtooth potential whose amplitude is periodically modulated in time. We show that, by using this formalism, a small set of measurements is enough to obtain the functional form for a wide range of parameters. This can be very helpful when characterizing experimentally the response of systems for which performing measurements is costly or difficult. PMID:25768567

  9. Specialist nurse training programme: dealing with asking for organ donation.

    The issue of cadaveric organ transplantation is by its very nature emotional as it is associated with the very traumatic time of a loved one's death. Making a request for organs needs to be handled very sensitively by health professionals when discussing the issue with a family. Those nurses working in critical care areas are most likely to confront this issue and need to be equipped for dealing with ensuing events. The major challenge for the nurse is to address the concerns with brain death and organ donation in an environment of grief and sadness. Asking for organ consent is the most important element of all and needs to be done in the most sensitive manner, providing appropriate support to the donor family. To facilitate this process specialist training programmes in the nursing curriculum are imperative. Education programmes should incorporate presentations, role play situations and discussions based upon past experiences of organ requests. This would hopefully result in increased rates of donor consent and thereby a reduction in transplant waiting lists. PMID:9725739

  10. Dealing with hidden issues: trafficked women in Nepal.

    This article discusses approaches to dealing with prostitution in Nepal and exportation of women prostitutes to Asia and the Middle East. It is estimated that over 200,000 Nepalese women are in Indian brothels, and tens of thousands are exported each year to other countries and forced either into prostitution or other oppressive conditions. In Nepal, women prostitutes are rejected as wives or daughters, regardless of the reasons involved. Women Acting Together for Change (WATCH) organized a national public hearing in June 1995 on these issues. During the hearing, 11 women and one man shared their views about being forced into prostitution, the ineffectiveness of the law, and social rejection. Participants at this forum questioned the legal practice of human rights and decided that law was a hindrance. Government representatives on the "listening bench" responded defensively and argued that prostitutes were unwilling to use the law, but agreed that the government should punish traffickers and commit politically to ending the trafficking in women. Roundtable discussions among concerned people after a day of hearings decided to initiate a nationwide coalition against the trafficking in women. The alliance would consist of 17 people and include nongovernmental representatives, lawyers, women who testified, representatives of the National Planning Council, and representatives from women's groups. The sex trade is viewed as a part of the national economy and a very profitable enterprise. Extreme poverty and few employment options are strong incentives for the continuation of prostitution. Patriarchal norms reinforce the view of women as born for the sexual pleasure of men. Nepal's national economy and policies have contributed to family poverty and to migration to other countries where women are exploited. The forum revealed schisms in the government commitment to Article 20 of the constitution. PMID:12291818

    This manuscript deals with the identification of protein residues in amphorae, including particularly identification of protein species. The work described was performed on fishes, the anchovy (Engraulis encrasicolus) and bonito (Sarda sarda) species frequently found in the Mediterranean area. Based on proteomic techniques, the analytical strategy was adapted to analysis of protein residues from tiny ceramic fragments. The major difficulty was to extract proteins and limit their hydrolysis during the sample preparation; consequently, multiple soft extraction techniques were evaluated. The most valuable results were obtained using a solution containing high amounts of denaturing agents, urea and thiourea, reducing agent, dithiothreitol, and detergent, 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate. The analysis using nano liquid chromatography-nano electrospray ionization double quadrupole time-of-flight mass spectrometry resulted in the identification of up to 200 proteins for the anchovy and bonito species, among which 73 peptides were found to be fish-specific. Because bonito and anchovy species are not documented and fully sequenced in genomic databases, the preliminary protein identification was realized via sequence homology to other fish sequenced species. Amino acid substitutions of peptides were assigned on the basis of the interpretation of tandem mass spectrometry spectra using de novo sequencing; these peptides, not reported up to now in databases, constitute species-specific markers. The method developed was finally applied to an archaeological sample replica impregnated with a mixture of fish tissue from both species; this experiment successfully led to the identification of 17 fish proteins, including 33 fish-specific peptides. This work shows that the analytical method developed has great potential for the identification of protein species in complex archaeological samples. PMID:20890751

    The recognition of victims of violence and their treatment in medical facilities is a subject which has been covered for several years in a number of ways. In medicine and in other disciplines, the focus of research, publication, and practical work has been on the quality of care provided. Guidelines for the treatment of victims of violence have been developed and needs have been assessed. These examples show there is an abundance of knowledge on the subject. Nevertheless, the transfer of this knowledge into the everyday practice of medicine at hospitals and doctors' offices is clearly still not functioning in an optimal way and faces a wide range of hurdles and stumbling blocks. Based on the experience gained in a pilot project involving the medical intervention in doctors' offices against violence perpetuated against women (Project MIGG, funded by the German Federal Ministry of Family, Senior Citizens, Women and Youth (BMFSFJ)), approaches for the optimal treatment of victims of violence in outpatient medical facilities are presented. The key steps to achieving the goal of optimal treatment are: (i) the entire practice team commits to establishing a victim-centered approach to care and (ii) the necessary processes and structures are implemented (i.e., adequate documentation in patient records, patient information is made available in the doctor's office, information on post-treatment services and sources of support in the region are provided, contact is maintained with such institutions, and programs of further education are offered). This paper provides a catalogue of keywords with an overview illustrating how to optimize practice management to deal with cases of domestic violence. In addition, various areas of work are described, such the special requirements involving the collection of evidence. PMID:26519330

    We investigate the effects of double-dealing behavior on cooperation in evolutionary games. Each individual in a population has two attributes: character and action. One's action may be consistent with one's character or not. We provide analytical results by a mean-field description of evolutionary prisoner's dilemma games (PDGs). Moreover, we give numerical results on different networks, ranging from square lattices to scale-free networks (SFNs). Two important conclusions have been drawn from the results on SFNs. Firstly, if only non-influential individuals (those with low degrees) have chances of becoming double-dealers, cooperation is certain to deteriorate. Secondly, when influential individuals (those with high degrees) adopt double-dealing behavior moderately, cooperation would be enhanced, which is in opposition to the traditional belief. These results help us to understand better the social phenomenon of the existence of double-dealers. In addition to the PDG, other types of games including the snowdrift game, the stag-hunt game and the harmony game have also been studied on our model. The results for these three games are also presented, which are consistent with the results for the PDG qualitatively. Furthermore, we consider our model under the co-evolution framework, in which the probability of an individual changing into a double-dealer and the individual strategy both could evolve during the evolutionary process.

  15. GNSS Reference Station Provider - How to deal with ITRF updates ?

    2015-04-01

    In 2015 a new ITRS Realization (most likely ITRF2013) will be issued. Regular ITRF updates are required for instance to integrate recently established reference stations to the ITRF and to improve site velocity estimates of already long time existing stations. Discussions how to optimally account for sudden coordinate shifts (e.g. caused by earthquakes) or periodical site motions (e.g. due to ground water flow, …) are always ongoing. Regional GNSS reference services usually tie their reference site coordinates to an almost recent ITRF at a fixed epoch or to a continental frame aligned to a tectonic plate (in Europe ETRFxx (ETRS89)). Therefore, the coordinates established in difference mode by users of such a service refer to this providers frame. In general a new ITRF update does not require any urgent action by the reference station provider as users are mostly interested in stable global coordinates and fixed relations to the national datum. On the other hand, currently upcoming un-differenced GNSS precise positioning techniques allow for dm or even sub-dm accuracy in post-processing, via RT-correction streams or via SIS. These coordinates are referred to the frame of the precise orbit and satellite information, which is the most current ITRF at the epoch of date. Therefore PPP coordinates established in 2014 differ for example from ETRF-coordinates by about 60cm or by at least 30cm from ITRF coordinates which refer to epoch 2000,0. This poster presentation aims to discuss how a GNSS reference station provider has to deal with an ITRF update in order to ensure on the one hand consistency of the user coordinates established in difference or PPP mode and to allow the user to obtain coordinates in the desired reference frame (most recent ITRF, ETRF, national datum). The required suite of actions includes changes of the reference site coordinates, the provision of transformation tools for post-processing users and the delivery of Real-Time RTCM corrections streams

  16. Challenges dealing with depleted uranium in Germany - Reuse or disposal

    2007-07-01

    During enrichment large amounts of depleted Uranium are produced. In Germany every year 2.800 tons of depleted uranium are generated. In Germany depleted uranium is not classified as radioactive waste but a resource for further enrichment. Therefore since 1996 depleted Uranium is sent to ROSATOM in Russia. However it still has to be dealt with the second generation of depleted Uranium. To evaluate the alternative actions in case a solution has to be found in Germany, several studies have been initiated by the Federal Ministry of the Environment. The work that has been carried out evaluated various possibilities to deal with depleted uranium. The international studies on this field and the situation in Germany have been analyzed. In case no further enrichment is planned the depleted uranium has to be stored. In the enrichment process UF{sub 6} is generated. It is an international consensus that for storage it should be converted to U{sub 3}O{sub 8}. The necessary technique is well established. If the depleted Uranium would have to be characterized as radioactive waste, a final disposal would become necessary. For the planned Konrad repository - a repository for non heat generating radioactive waste - the amount of Uranium is limited by the licensing authority. The existing license would not allow the final disposal of large amounts of depleted Uranium in the Konrad repository. The potential effect on the safety case has not been roughly analyzed. As a result it may be necessary to think about alternatives. Several possibilities for the use of depleted uranium in the industry have been identified. Studies indicate that the properties of Uranium would make it useful in some industrial fields. Nevertheless many practical and legal questions are open. One further option may be the use as shielding e.g. in casks for transport or disposal. Possible techniques for using depleted Uranium as shielding are the use of the metallic Uranium as well as the inclusion in concrete

    The main purpose of this study is to evaluate marginal abatement cost of the main agricultural pollutants. In this sense, we construct three indices including Net Global Warming Potential (NGWP) and Nitrogen Surplus (NS), simulated by a biogeochemistry model, and also an Environmental Impact Quotient (EQI) for paddy fields. Then, using a Data Envelopment Analysis (DEA) model, we evaluate environmental inefficiencies and shadow values of these indices. The results show that there is still room for improvement at no extra cost just through a better input management. Besides, enormous potential for pollution reduction in the region is feasible. Moreover, in paddy cultivation, marginal abatement cost of pesticides and herbicides are much bigger than nitrogen surplus and greenhouse gasses. In addition, in the status quo, the mitigation costs are irrelevant to production decisions. Finally, to deal with the private pollution costs, market-based instruments are proved to be better than command-and-control regulation. PMID:26998602

  1. Dealing with uncertainty in the chemical environment in bentonite backfill

    Analytical and conceptual deficiencies in understanding compositional variability in the smectite clays are expected to generate uncertainty in models used to simulate the chemical environment in bentonite backfill. Equilibrium models accounting for nonstoichiometry in smectite can nevertheless bound ranges in aqueous solution compositions that are an explicit function of the uncertainty in smectite compositions. In one approach, we quantify uncertainty in terms of ranges in concentrations of octahedral and tetrahedral Al, and exchange-site cations and vacancies. Heterogeneous mass transfer in bentonite-water systems is modeled using conventional mass-action relations and standard Gibbs energies for stoichiometric minerals, and the site-occupancy constraints combined with site-mixing relations for smectite. The resultant bounding conditions in groundwater compositions may be large or small depending on which aqueous species are of interest in a given situation, but they are valid irrespective of whether equilibrium in smectite-water reaction is attained or is inhibited by slow intracrystalline reaction rates.

    The intensive human use of high mountains intersects more and more with the hazard zones of such environments. Because of the complexity of such processes and impacts, dealing with such risks requires a broad education in many sub-domains of the earth sciences and the socio-economic field. Inter- and trans-disciplinary training and education of professionals is therefore essential. Thus the goal of the Swiss Virtual Campus project "Dealing with Natural Hazards" is to provide such a course program covering the basics of dealing with natural hazards, including technical, environmental and social aspects. In the field of natural hazards and risk management, education at the Swiss universities is mostly structured in narrow sectors. Using the advantages of the internet, the Virtual Campus provides teachers and students an interdisciplinary discussion platform on the integral approach and the handling with natural hazards. The course content is organised in 5 modules: 1 basic knowledge and tools, 2 hydrological / meteorological hazards, 3 geological hazards, 4 vulnerability of property and of socio-economic systems and 5 integral natural risk management. To ensure a national and international access the courses are designed in English and published on the internet. Within the scope of this project we are developing lessons in the subject area of natural hazards related to glaciers and permafrost. These are ice avalanches, glacier floods, glacier length variations and permafrost. The content is divided into chapters, which are consistent over the entire module: (1) processes: characterisation of the different processes, (2) triggering: initiating events, (3) data acquisition, mapping and monitoring: appropriate methods, (4) estimation models: application of the adequate model, (5) combinations and interactions: interrelation and impacts of different hazards, (6) long-term effects: global change effects, (7) integral hazard recognition and assessment: integral proceedings

    Nix was first described in the heart as the protein product of a differentially expressed mRNA detected by hybridiztion to a partial cDNA sequence tag on an RNA expression array. Over the subsequent 8 years Nix has become the prototypical transcriptionally-regulated cardiac myocyte “suicide” gene and has been used as a model to interrogate mechanisms of programmed cardiomyocyte death in hypertrophy and heart failure. Nix stimulates conventional apoptosis mediated via the intrinsic mitochondrial pathway, but emerging evidence indicates that Nix also controls programmed necrosis dependent upon sarcoplasmic reticular-mitochondrial tethering, calcium cross-talk, and the mitochondrial permeability transition. Recent studies have also described Nix labeling of senescent cardiomyocyte mitochondria for autophagic elimination, elucidated a physiological mitochondrial quality control Nix function; so-called “mitochondrial pruning.

    2011-01-01

    Introduction Drug dealing among drug users has been associated with elevated risk-taking and negative health outcomes. However, little is known about the cessation of drug dealing among this population. Methods We assessed time to cessation of drug dealing using Cox regression. We also used generalized estimation equation (GEE) analysis and chi-square analysis to examine factors associated with willingness to cease drug dealing. Results In total, 868 participants reported drug dealing between November 2005 and March 2009. Among 381 participants dealing drugs at baseline, 194 (51%) ceased dealing. Incidence of dealing cessation was positively associated with spending less than $50 per day on drugs (Adjusted Hazard Ratio [AHR] = 1.88, 95% Confidence Interval [CI]: 1.14 - 3.10) and negatively associated with buying drugs from the same source (AHR = 0.60, 95% CI: 0.37 - 0.98). In a GEE analysis, willingness to cease dealing was positively associated with older age (Adjusted Odds Ratio [AOR] = 1.02, 95% CI: 1.01 - 1.03), crack use (AOR = 2.00, 95% CI: 1.44 - 2.79), public injecting (AOR = 1.95, 95% CI: 1.55 - 2.43), and reporting that police presence affects drug purchases (AOR = 1.53, 95% CI: 1.22 - 1.91), and negatively associated with crystal methamphetamine injection (AOR = 0.62, 95% CI: 0.47 - 0.83). Discussion Intensity of drug use and acquisition method were predictive of dealing cessation. Willingness to cease dealing was associated with a range of risky drug-related activities. Interventions to reduce drug dealing should be conceived in tandem with addiction treatment strategies. PMID:21664770

    Background and Aims AmapSim is a tool that implements a structural plant growth model based on a botanical theory and simulates plant morphogenesis to produce accurate, complex and detailed plant architectures. This software is the result of more than a decade of research and development devoted to plant architecture. New advances in the software development have yielded plug-in external functions that open up the simulator to functional processes. Methods The simulation of plant topology is based on the growth of a set of virtual buds whose activity is modelled using stochastic processes. The geometry of the resulting axes is modelled by simple descriptive functions. The potential growth of each bud is represented by means of a numerical value called physiological age, which controls the value for each parameter in the model. The set of possible values for physiological ages is called the reference axis. In order to mimic morphological and architectural metamorphosis, the value allocated for the physiological age of buds evolves along this reference axis according to an oriented finite state automaton whose occupation and transition law follows a semi-Markovian function. Key Results Simulations were performed on tomato plants to demostrate how the AmapSim simulator can interface external modules, e.g. a GREENLAB growth model and a radiosity model. Conclusions The algorithmic ability provided by AmapSim, e.g. the reference axis, enables unified control to be exercised over plant development parameter values, depending on the biological process target: how to affect the local pertinent process, i.e. the pertinent parameter(s), while keeping the rest unchanged. This opening up to external functions also offers a broadened field of applications and thus allows feedback between plant growth and the physical environment. PMID:17766310

    Mongolian Scots pine (Pinus sylvestris var. mongolica) is one of the principal tree species in the network of Three-North Shelterbelt for windbreak and sand stabilisation in China. The functions of shelterbelts are highly correlated with the architecture and eco-physiological processes of individual tree. Thus, model-assisted analysis of canopy architecture and function dynamic in Mongolian Scots pine is of value for better understanding its role and behaviour within shelterbelt ecosystems in these arid and semiarid regions. We present here a single-tree functional and structural model, derived from the GreenLab model, which is adapted for young Mongolian Scots pines by incorporation of plant biomass production, allocation, allometric rules and soil water dynamics. The model is calibrated and validated based on experimental measurements taken on Mongolian Scots pines in 2007 and 2006 under local meteorological conditions. Measurements include plant biomass, topology and geometry, as well as soil attributes and standard meteorological data. After calibration, the model allows reconstruction of three-dimensional (3D) canopy architecture and biomass dynamics for trees from one- to six-year-old at the same site using meteorological data for the six years from 2001 to 2006. Sensitivity analysis indicates that rainfall variation has more influence on biomass increment than on architecture, and the internode and needle compartments and the aboveground biomass respond linearly to increases in precipitation. Sensitivity analysis also shows that the balance between internode and needle growth varies only slightly within the range of precipitations considered here. The model is expected to be used to investigate the growth of Mongolian Scots pines in other regions with different soils and climates. PMID:22927982

  9. How to deal with climate change uncertainty in the planning of engineering systems

    NASA Astrophysics Data System (ADS)

    Spackova, Olga; Dittes, Beatrice; Straub, Daniel

    2016-04-01

    The effect of extreme events such as floods on the infrastructure and built environment is associated with significant uncertainties: These include the uncertain effect of climate change, uncertainty on extreme event frequency estimation due to limited historic data and imperfect models, and, not least, uncertainty on future socio-economic developments, which determine the damage potential. One option for dealing with these uncertainties is the use of adaptable (flexible) infrastructure that can easily be adjusted in the future without excessive costs. The challenge is in quantifying the value of adaptability and in finding the optimal sequence of decision. Is it worth to build a (potentially more expensive) adaptable system that can be adjusted in the future depending on the future conditions? Or is it more cost-effective to make a conservative design without counting with the possible future changes to the system? What is the optimal timing of the decision to build/adjust the system? We develop a quantitative decision-support framework for evaluation of alternative infrastructure designs under uncertainties, which: • probabilistically models the uncertain future (trough a Bayesian approach) • includes the adaptability of the systems (the costs of future changes) • takes into account the fact that future decisions will be made under uncertainty as well (using pre-posterior decision analysis) • allows to identify the optimal capacity and optimal timing to build/adjust the infrastructure. Application of the decision framework will be demonstrated on an example of flood mitigation planning in Bavaria.

  11. Multiple Imputation by Fully Conditional Specification for Dealing with Missing Data in a Large Epidemiologic Study

    PubMed Central

    Liu, Yang; De, Anindya

    2016-01-01

    Missing data commonly occur in large epidemiologic studies. Ignoring incompleteness or handling the data inappropriately may bias study results, reduce power and efficiency, and alter important risk/benefit relationships. Standard ways of dealing with missing values, such as complete case analysis (CCA), are generally inappropriate due to the loss of precision and risk of bias. Multiple imputation by fully conditional specification (FCS MI) is a powerful and statistically valid method for creating imputations in large data sets which include both categorical and continuous variables. It specifies the multivariate imputation model on a variable-by-variable basis and offers a principled yet flexible method of addressing missing data, which is particularly useful for large data sets with complex data structures. However, FCS MI is still rarely used in epidemiology, and few practical resources exist to guide researchers in the implementation of this technique. We demonstrate the application of FCS MI in support of a large epidemiologic study evaluating national blood utilization patterns in a sub-Saharan African country. A number of practical tips and guidelines for implementing FCS MI based on this experience are described.

  12. Fossils out of sequence: Computer simulations and strategies for dealing with stratigraphic disorder

    SciTech Connect

    Cutler, A.H.; Flessa, K.W. )

    1990-06-01

    Microstratigraphic resolution is limited by vertical mixing and reworking of fossils. Stratigraphic disorder is the degree to which fossils within a stratigraphic sequence are not in proper chronological order. Stratigraphic disorder arises through in situ vertical mixing of fossils and reworking of older fossils into younger deposits. The authors simulated the effects of mixing and reworking by simple computer models, and measured stratigraphic disorder using rank correlation between age and stratigraphic position (Spearman and Kendall coefficients). Mixing was simulated by randomly transposing pairs of adjacent fossils in a sequence. Reworking was simulated by randomly inserting older fossils into a younger sequence. Mixing is an inefficient means of producing disorder; after 500 mixing steps stratigraphic order is still significant at the 99% to 95% level, depending on the coefficient used. Reworking disorders sequences very efficiently: significant order begins to be lost when reworked shells make up 35% of the sequence. Thus a sequence can be dominated by undisturbed, autochthonous shells and still be disordered. The effects of mixing-produced disorder can be minimized by increasing sample size at each horizon. Increased spacing between samples is of limited utility in dealing with disordered sequences: while widely separated samples are more likely to be stratigraphically ordered, the smaller number of samples makes the detection of trends problematic.

  13. Assessing methods for dealing with treatment switching in randomised controlled trials: a simulation study

    PubMed Central

    2011-01-01

    Background We investigate methods used to analyse the results of clinical trials with survival outcomes in which some patients switch from their allocated treatment to another trial treatment. These included simple methods which are commonly used in medical literature and may be subject to selection bias if patients switching are not typical of the population as a whole. Methods which attempt to adjust the estimated treatment effect, either through adjustment to the hazard ratio or via accelerated failure time models, were also considered. A simulation study was conducted to assess the performance of each method in a number of different scenarios. Results 16 different scenarios were identified which differed by the proportion of patients switching, underlying prognosis of switchers and the size of true treatment effect. 1000 datasets were simulated for each of these and all methods applied. Selection bias was observed in simple methods when the difference in survival between switchers and non-switchers were large. A number of methods, particularly the AFT method of Branson and Whitehead were found to give less biased estimates of the true treatment effect in these situations. Conclusions Simple methods are often not appropriate to deal with treatment switching. Alternative approaches such as the Branson & Whitehead method to adjust for switching should be considered.

    Twenty-three Taiwanese infants with unilateral cleft lip and palate (UCLP) were CT-scanned before lip repair at the age of 3 months, and again after lip repair at the age of 12 months. In order to evaluate the surgical result, detailed point correspondence between pre- and post-surgical images was needed. We have previously demonstrated that non-rigid registration using B-splines is able to provide automated determination of point correspondences in populations of infants without cleft lip. However, this type of registration fails when applied to the task of determining the complex deformation from before to after lip closure in infants with UCLP. The purpose of the present work was to show that use of prior information about typical deformations due to lip closure, through the construction of a knowledge-based atlas of deformations, could overcome the problem. Initially, mean volumes (atlases) for the pre- and post-surgical populations, respectively, were automatically constructed by non-rigid registration. An expert placed corresponding landmarks in the cleft area in the two atlases; this provided prior information used to build a knowledge-based deformation atlas. We model the change from pre- to post-surgery using thin-plate spline warping. The registration results are convincing and represent a first move towards an automatic registration method for dealing with difficult deformations due to this type of surgery.

    The boiler industry has asked the US Department of Commerce to protect it from what it claims may be secret illegal financing deals by foreign suppliers. Complaints by the American Boiler Manufacturers Association (ABMA) cite two cases involving French and Swedish suppliers and warn of South American deals under consideration.

Those purchasing the impartial boilers deny that anything improper or illegal was done. (DCK)

  1. Dealing with the safety paradox of delta-branches closure; a geomorphology study

    NASA Astrophysics Data System (ADS)

    Sloff, C.; Tromp, R.; Sieben, A.

    2013-12-01

    Closing off estuaries by dams is a conventional solution to reduce flood risks and salt intrusion in river deltas. However, if not all branches are closed, residual tidal currents develop or increase in connecting channels between the closed and open branches. These channels start to erode, causing bank instability and possible failure of levees. Hence, paradoxically, the intended increase in safety by this closure creates a new threat with increased flood risks. We illustrate this for existing channel erosion and dike stability problems in the Dutch Rhine River delta in the Netherlands, as well as for proposed future closure works in the Mekong River in Vietnam. Crucial for assessing and dealing with the erosion problems, is a proper prediction of flow conditions and of bed erodibility. The channels incise ancient deltaic deposits, consisting of diverse sections and layers of sand, clay and peat with diverse states of compaction. In the presented studies we show how we applied Delft3D to model the full delta, with all relevant dynamics and complex interactions between tidal flow and river discharges. For the Dutch situation, we simulated the long-term fate of the eroding interconnecting channels, applying a detailed description of subsurface heterogeneous erodibility (space and depth varying). Since these rivers are incising slowly in clay and peat beds covering highly-erodible sand layers, alternate sections occur of undersupplied ';fixed' beds, and of very deep scour holes. For the Vietnam case, we show how the location of a barrier and operation of gates, can be used to control both the salinity intrusion and channel erosion for the Mekong delta. Although the morphology studies for the Dutch delta with high-density data availability obviously justify a detailed Delft3D approach, it is shown that even in the Mekong delta with poor data quality, a coarse-grid large-scale Delft3D model can provide the answers necessary for planning the closure works and potential

  2. Developing a national system for dealing with adverse events following immunization.

    2000-01-01

    Although vaccines are among the safest of pharmaceuticals, the occasional severe adverse event or cluster of adverse events associated with their use may rapidly become a serious threat to public health. It is essential that national monitoring and reporting systems for vaccine safety are efficient and adequately coordinated with those that conventionally deal with non-vaccine pharmaceuticals. Equally important is the need for an enlightened and informed national system to be in place to deal with public concerns and rapid evaluation of the risk to public safety when adverse events occur. Described in this article is the outcome of efforts by the WHO Global Training Network to describe a simple national system for dealing with vaccine safety and with emergencies as they arise. The goals of a training programme designed to help develop such a system are also outlined. PMID:10743281

    The article discusses the development of the Index for Dealing with Family Violence to assess municipal strategies related to this violation of children's and adolescents' rights. Development of the index involved a preliminary analysis of indicators from previous studies and a technical expert group. Four indicators were selected: the existence of a municipal plan for dealing with violence against children and adolescents; the existence of an inter-sector flow for treating and following up on children and adolescents in situations of family violence; number of guardianship councils in relation to the municipality's population; and the existence of standardized instruments in municipal school, social work, and health systems for reporting situations of violence against children and adolescents. The databank from a previous study was used in an exercise to apply the indicator in four Brazilian state capitals. The indicator can serve as a tool for monitoring and mobilizing efforts to implement measures for dealing with family violence. PMID:26375649

    2016-01-01

    Given that chemotherapy treatments are done mostly in an outpatient setting, patients with cancer must deal with treatment-related symptoms mainly at home. Evidence suggests that they often feel left alone or unprepared to do so. This qualitative study explores how patients deal with chemotherapy-related symptoms in their home, which factors and ideas influence their self-management and what role professional caregivers play. One-off, semi-structured interviews were held with 28 adult patients with cancer being treated with chemotherapy. Using a Grounded Theory approach, we cyclically collected and analysed data to come to a thorough understanding of the major conceptual themes and their interconnections. Dealing with chemotherapy-related symptoms involves a process of experiencing and learning how side effects unfold over time and how to deal with them. Patients express very personal symptom experiences and symptom-management styles, which are shaped by personal factors (e.g. coping with cancer and cancer treatment, perceived level of control) and environmental factors (e.g. professionals' attitude, information resources). Improving symptom self-management support requires active exploration of the personal symptom experience and symptom-management style. Professional care should be tailored to the patient's perspective and should address personal and environmental determinants of their behaviour. PMID:25752741

  6. Employee-oriented leadership and quality of working life: mediating roles of idiosyncratic deals.

    2011-02-01

    Leader consideration has long been suggested to be conducive to quality of working life experienced by employees. The present study links this classic leadership dimension with more recent research on idiosyncratic deals, referring to personalized conditions workers negotiate in their employment relationships. A two-wave survey study (N = 159/142) among German hospital physicians suggests that authorizing idiosyncratic deals is a manifestation of employee-oriented leader behavior. Consideration had consistent positive effects on idiosyncratic deals regarding both professional development and working time flexibility. These two types had differential effects on two indicators of the quality of working life. Development related positively to work engagement, flexibility related negatively to work-family conflict. Cross-lagged correlations supported the proposed direction of influence between consideration and idiosyncratic deals in a subsample of repeating responders (n=91). The relation between development and engagement appeared to be reciprocal. Longitudinal results for the association between flexibility and work-family conflict were inconclusive. PMID:21526592

  5. Teens’ Self-Efficacy to Deal with Dating Violence as Victim, Perpetrator or Bystander

    PubMed Central

    Van Camp, Tinneke; Hébert, Martine; Guidi, Elisa; Lavoie, Francine; Blais, Martin

    2015-01-01

    Multiple studies have demonstrated that adolescent dating violence is highly prevalent and associated with internalizing and externalizing problems. A number of prevention initiatives are being implemented in North-American high schools. Such initiatives do not only aim to raise awareness among potential victims and offenders but also among peer bystanders. Since teenagers mainly reach out to their peers when experiencing adversity, it is important to address adolescents’ efficiency to deal with witnessing dating violence or with friends disclosing dating abuse, in addition to increasing ability to deal with experienced dating violence victimization or perpetration. The aim of this study is to explore adolescents’ self-efficacy to deal with dating violence victimization and perpetration in their relationships and those of their peers. A paper-and-pencil questionnaire was completed by 259 14–18 years olds in Quebec, Canada. The data allows building insight into adolescents’ confidence to reach out for help or to help others in a situation of dating violence victimization and perpetration. We also considered the impact of gender and dating victimization history. Results suggest that dating violence prevention can build on teens’ self-efficacy to deal with dating violence and offer them tools to do so efficiently. PMID:26807554

    2011-01-15

    The aim was to investigate if engineered endophytes that are capable of degrading organic contaminants, and deal with or ideally improve uptake and translocation of toxic metals, can improve phytoremediation of mixed organic-metal pollution. As a model system, yellow lupine was inoculated with the endophyte Burkholderia cepacia VM1468 possessing (a) the pTOM-Bu61 plasmid, coding for constitutive toluene/TCE degradation, and (b) the chromosomally inserted ncc-nre Ni resistance/sequestration system. As controls, plants were inoculated with B. vietnamiensis BU61 (pTOM-Bu61) and B. cepacia BU72 (containing the ncc-nre Ni resistance/sequestration system). Plants were exposed to mixes of toluene and Ni. Only inoculation with B. cepacia VM1468 resulted in decreased Ni and toluene phytotoxicity, as measured by a protective effect on plant growth and decreased activities of enzymes involved in antioxidative defence (catalase, guaiacol peroxidase, superoxide dismutase) in the roots. Besides, plants inoculated with B. cepacia VM1468 and B. vietnamiensis BU61 released less toluene through the leaves than non-inoculated plants and those inoculated with B. cepacia BU72. Ni-uptake in roots was slightly increased for B. cepacia BU72 inoculated plants. These results indicate that engineered endophytes have the potential to assist their host plant to deal with co-contamination of toxic metals and organic contaminants during phytoremediation.

    Unsworth, Kerrie L.; Russell, Sally V.; Davis, Matthew C.

    2016-01-01

    In this paper, we argue that individuals – as members of society – play an important role in the expectations of whether or not companies are responsible for addressing environmental issues, and whether or not governments should regulate them. From this perspective of corporate social responsibility as a social contract we report the results of a survey of 1066 individuals. The aim of the survey was to assess participants’ belief in anthropogenic climate change, free-market ideology, and beliefs around who is responsible for dealing with climate change. Results showed that both climate change views and free market ideology have a strong effect on beliefs that companies are responsible for dealing with climate change and on support for regulatory policy to that end. Furthermore, we found that free market ideology is a barrier in the support of corporate regulatory policy. The implications of these findings for research, policy, and practice are discussed.

Case Presentation This cross-sectional study was carried in 2011 and all of the hospitals which were located in the northern areas of Iran were investigated through the census method. The data collection instruments were self-administered Managers’ Awareness Questionnaire (40 items) and a 141-item checklist. The mean percentage score of hospitals in management of the unanticipated disasters program in the hospital was good. The mean score of managers’ awareness of the hospital status was moderate. With the increase in managers’ awareness, the preparedness of the hospitals significantly increased (r = 0.73, P < 0.001). Conclusions The findings showed the moderate preparedness of the hospitals in the Northern provinces to deal with disasters. PMID:24349752

    Lönngren, Johanna; Svanström, Magdalena; Ingerman, Åke; Holmberg, John

    2016-05-01

    The concept of perspectives is important in discussions about the multidimensionality of sustainability problems and the need to consider many different aspects when dealing with them. This paper aims to facilitate discussions among both educators and researchers about didactical approaches to developing students' abilities to deal with the multidimensionality of sustainability challenges through the use of multiple perspectives. For this purpose, a theoretical framework was developed that describes perspectives in terms of a set of general characteristics, as well as a number of ways in which students can develop and reflect on perspectives. Development of the framework was supported by a qualitative content analysis of transcripts from interviews with undergraduate engineering students in Sweden.

  2. Use of sensors to deal with uncertainty in realistic robotic environments

    NASA Astrophysics Data System (ADS)

    Cervera, Enrique; del Pobil, Angel P.; Marta, Edward; Serna, Miguel A.

    1995-04-01

    This work is an application of Kohonen's self-organizing feature maps, to deal with uncertainty in realistic robotic environments. The neural network is fed with the signals of a force sensor attached to the wrist of the robot arm. The learning process consists of two phases: a training phase and a labeling phase. After training, the clusters of the map are associated to contact states. There are potential uncertainties in the positions of the elements, which cause error situations, like incorrect grasping of a piece or bad insertions. The error situations can be associated with clusters in the network. As a result of the application of this learning scheme, we can state that Kohonen's self-organizing feature maps are well suited for dealing with uncertainty in realistic robotic environments, particularly robot pick-and-place operations. They are easy to apply and powerful, and are a step towards the solution of more complex intelligent tasks.

    The present paper discusses children who have been the victims of sexual abuse in their own family. It focuses on the special role of pediatricians and medical staff in identifying such children and providing them with initial assistance by reporting the situation to the authorities. The first part of the paper surveys the short- and long-term effects of childhood sexual abuse, including the physical and emotional impact of sexual exploitation and severe neglect. This section discusses the symptoms shown by abused children, and how they express and deal with their trauma. It is extremely important for pediatricians to be sensitive to the possibility of patients being abused at home, as this is an area still largely regarded as a societal taboo. Also included in this section a discussion of the effects that are manifested when the victim has grown to adulthood, such as personality disorders. The second part of the paper deals with how pediatricians must act when they encounter such a situation in which they suspect sexual abuse in the family. They should strive to identify the problem and bring it to the attention of the authorities. Discovery of the problem is the most vital part of the path to the victim's recovery. The paper also discusses the aspect of treatment, advising doctors who encounter this problem on ways of dealing with it. PMID:22389771

    Objectives: To estimate the prevalence of emergency cases reporting to Primary Health Care centers (PHC), Jeddah, Saudi Arabia and to explore the barriers facing PHC physicians when dealing with such emergency cases. Methods: A cross-sectional analytic study, where all physicians working in the PHC of the Ministry of Health (MOH) in Jeddah; were invited to participate (n=247). The study period was from July 2013 till December 2013. Data were collected through two sources. 1- A self-administered questionnaire used to determine the physicians’ perceived competence when dealing with emergency cases. 2- A structured observation sheet used to evaluate availability of equipment, drugs, ambulances and other supporting facilities required to deal with emergency cases. Results: The response rate was 83.4%. The physicians’ age ranged between 25 and 60 years with a mean ±SD of 34.4±7.5 years. Majority of them (83.5%) did not attend ATLS courses at all whereas 60.7% never attended ACLS courses. The majority (97.1%) had however attended BLS courses. Physicians in the age group 36-45 years, non-Saudi, those who had SBFM, those who reported experience in working in emergency departments and physicians who reported more working years in PHCCs (>5 years) had a significant higher score of perceived level of competence in performing emergency skill scale than others (P<0.05). The prevalence of emergency cases attending PHC in Jeddah (2013) was 5.2%. Conclusion: Emergency services at PHC in Jeddah are functioning reasonably well, but require fine tuning of services and an upgrade in their quality. PMID:27045411

  10. The role of domain expertise and judgment in dealing with unexpected events

    NASA Astrophysics Data System (ADS)

    Kochan, Janeen Adrion

    Unexpected events, particularly those creating surprise, interrupt ongoing mental and behavioral processes, creating an increased potential for unwanted outcomes to the situation. Human reactions to unexpected events vary. One can hypothesize a number of reasons for this variation, including level of domain expertise, previous experience with similar events, emotional connotation, and the contextual surround of the event. Whereas interrupting ongoing activities and focusing attention temporarily on a surprising event may be a useful evolutionary response to a threatening situation, the same process may be maladaptive in today's highly dynamic world. The purpose of this study was to investigate how different aspects of expertise affected one's ability to detect and react to an unexpected event. It was hypothesized that there were two general types of expertise, domain expertise and judgment (Hammond, 2000), which influenced one's performance on dealing with an unexpected event. The goal of the research was to parse out the relative contribution of domain expertise, so the role of judgment could be revealed. The research questions for this study were: (a) Can we identify specific knowledges and skills which enhance one's ability to deal with unexpected events? (b) Are these skills "automatically" included in domain expertise? (c) How does domain expertise improve or deter one's reaction and response to unexpected events? (d) What role does judgment play in responding to surprise? The general hypothesis was that good judgment would influence the process of surprise at different stages and in different ways than would domain expertise. The conclusions from this research indicated that good judgment had a significant positive effect in helping pilots deal with unexpected events. This was most pronounced when domain expertise was low.

    In September 1991 the Health Care Financing Administration touched off a two-month scramble by issuing regulations sharply curtailing states' use of voluntary donations and provider taxes to raise money for Medicaid. Days and nights of intrigue and dealmaking followed. Finally, on the day before Thanksgiving, Congress, the Administration, and the nation's governors agreed to a deal that may resolve the matter. During the course of those talks, all sides honed their negotiating skills and, in the process, uncovered basic flaws in the U.S. health care system. PMID:10118223

    Objectives to determine how Family Health Strategy professionals recognize and deal with domestic violence in pregnant women. Method qualitative study based on the Theory of Praxis Intervention in Collective Health Nursing (TIPESC). Fourteen professionals at a Basic Health Unit in the east side of Sao Paulo/Brazil were interviewed. Empirical data were categorized and discussed in thematic groups. For data analysis was used the technique of Discourse Analysis. Results we identified low number of reported cases of domestic violence; lack of education and training of health care professionals; failure in the identification and intervention process due to bias on their personal problems, moral attitudes and prejudice against these women. In addition, the study showed that their labor process was based entirely on the biological aspects of the women and to overcome this, they need of proper rapport between health care professionals and pregnant women to deal with of domestic violence. Conclusion professionals should develop skills to intervene in violence against pregnant women and also modify labor processes considering women in their totality and part of society. PMID:25029056

  13. Recommendations for dealing with asphaltene or wax problems in offshore production facilities

    Many production facilities around the world suffer from either asphaltene or wax deposition. Asphaltene and wax problems are seriously threatening the economic production from many offshore reservoirs due to the high cost of remedial measures. Offshore production facilities are especially susceptible to asphaltene or wax deposition for a number of reasons. One indispensable requirement for dealing with these problems, that offshore production facilities usually lack, is extra storage capacity for temporarily storing asphaltene or wax cuttings and washings away from inflicted equipment. The cuttings and washings, even if temporary storage were available, need to be dealt with nearly on a daily basis. Providing equipment to process the slop offshore is expensive and messy (environmentally). Hence, the cuttings and washings, in many cases, must be carried away to onshore slop processing facilities. The above discussion assumes, of course, that the operator has already found the best technology (e.g., tools, chemicals, etc.) for removing the deposits from the offshore equipment, which in itself is another challenge that precedes the disposal problem. All of the above considerations underscore the fact that the best way of dealing with the asphaltene and wax problems is to prevent them, where possible. This paper presents ideas and methodologies on how to predict, diagnose, prevent, or mitigate problems caused by organic deposition in offshore production facilities. In one facility where these ideas were put to use, despite the debilitating magnitude of the asphaltene problems encountered, the field has been successfully produced for over 14 years with minimum environmental impact.

  14. The strategies used to deal with emotion work in student paramedic practice.

    Preregistration paramedic science students are quickly introduced to the reality of emergency paramedic practice (British Paramedic Association (BPA) 2008) and are expected to manage both their own emotions and those of potentially distressed patients and relatives. Despite the evident importance of emotion work, there is a lack of research evidence on this phenomenon and none at all from the student perspective. A qualitative study, using semi-structured interviews was undertaken with 8 s year paramedic science students to explore their perceptions and experiences of emotion work and the strategies used to deal with it. Thematic content analysis produced four themes, 'getting on with the job', 'struggling with emotion', 'talking it through' and humour. This paper focuses on the strategies used to help deal with the emotional demands of practice. Participants emphasised the importance of talking it through and 'off loading' with friends, colleagues, partners and their clinical mentor. Going through the job with their mentor centred on the technical aspects of care and helped to reassure students that they had done their best. Humour was another useful strategy which also helped students to 'off load' and move on after difficult experiences. These findings highlight the importance of talking about experiences within available support systems and the role of the clinical mentor in facilitating debriefing and reflection. It is crucial that paramedic students are also made aware of the support services available to them to ensure their emotional needs are met. PMID:23083896

    Abstract Background Natural disasters result in numerous economic, social, psychological and cultural consequences. Of them, psychological consequences of disasters will affect the lives of people long after the critical conditions finish. Thus, concerning the importance of psychological support in disasters, this study has identified problems and weaknesses in dealing with the psychological effects of the disasters occurred in Iran. Methods This qualitative study was carried out using semi-structured in-depth interviews and focus groups. Sample volume consisted of 26 experts in the field of disaster management. Content analysis was used to analyze data. Results Nine major problems were identified as weaknesses in handling the psychological effects of the disaster. These weaknesses include: rescuers’ unfamiliarity with the basic principles of psychosocial support, shortage of relevant experts and inadequate training, paying no attention to the needs of specific groups, weaknesses in organizational communications, discontinuation of psychological support after disaster, unfamiliarity with native language and culture of the disaster area, little attention paid by media to psychological principles in broadcasting news, people’s long-term dependence on governmental aid. Conclusions Disaster management has various aspects; in Iran, less attention has been paid to psychological support in disasters. Increasing education at all levels, establishing responsible structures and programming seem necessary in dealing with the psychological effects of disasters. PMID:25927043

    Dealing with the behavioral and psychological symptoms of dementia (BPSD) is often complex. Given the controversy with regard to antipsychotics for behavioral problems in people with dementia, there has been a renewed emphasis on nonpharmacological interventions, with progress in the design of the relevant studies. Potential nonpharmacological interventions for BPSD are: cognitive training/stimulation, rehabilitative care, activities of daily living, music therapy, massage/touch, physical activity, education/training of professionals, and education and psychosocial support of informal caregivers. Use of antipsychotics in the management of BPSD is controversial due to limited efficacy and the risk of serious adverse effects, but credible alternatives remain scarce. The problem of chronic use of antipsychotics in nursing homes should be tackled. Discontinuation of antipsychotic medication in older individuals with BPSD appears to be feasible. Discontinuation efforts are needed to differentiate between patients for whom antipsychotics have no added value and patients for whom the benefits outweigh the risks. PMID:26170729

    Verbal aggression has been defined as communication with an intention to harm an individual through words, tone or manner, regardless of whether harm occurs. It includes verbal threat to harm, ridicule, openly hostile remarks, unjust persistent criticism, shouting or yelling insults, as well as more covert actions such as spreading hurtful rumours (Cox, 1987; Farrell et al, 2006). Receiving verbal aggression from a patient has been closely associated with psychological distress which may negatively affect work performance. A verbal aggression work book was developed to help nursing staff to deal with verbal aggression from patients in clinical practice. This was piloted over a six-week period with 18 nurses working on one acute psychiatric inpatient ward. Findings revealed that the intervention had some promising effects. However, much more attention needs to be paid to changing attitudes towards verbal aggression. PMID:20505614

    When reading medical literature as a clinician, many different measures of association are presented. To judge whether results of studies can be applied to clinical practice, it is essential to understand and to be able to interpret the measure of association reported in the article. In this paper, we will present how to deal with the most commonly used measures of association including the risk and rate difference, number needed to treat, risk and rate ratio, hazard ratio and odds ratio. By means of examples, we will discuss the different measures of association for the three main study designs used in clinical research: randomized controlled trial, observational cohort study and case-control study.

    The article covers scientific hygienic positions in forming and solving the acute scientific and technical problem of dealing with waste. The given problem is topical due to growing amount and diversity of waste and relatively small knowledge of ecological, medical and biological aspects of the problem. The paper covers the entire "life cycle" of waste, chiefly industrial and communal, as the most diverse and potentially dangerous to the environment. Special attention is paid to neutralization and recycling of waste for its application as secondary material in various branches of national economy. Having critically analized the results of complex studies, the authors conclude the article with outlining the prospective tasks of research for scientific and practical institutions of sanitary surveillance of Russian Federation Ministry of Health.

    Ethical problems in healthcare in Lithuania are identified, existing mechanisms that deal with them are analysed and policy implications are discussed. At least three groups of ethical problems exist in the Lithuanian healthcare system: problems in the healthcare reform process, in interprofessional interaction and in doctor–patient relationships. During the past 15 years, several diverse legal, political and administrative mechanisms have been implemented in Lithuania to tackle these problems. Despite major achievements, numerous problems persist, implying that the focus should be shifted to different mechanisms and interventions. It is necessary to broaden the conceptual understanding of ethics in healthcare and focus on management ethics to tackle ethical problems in Lithuania or in other countries in transition.

    Mitigation measures for tackling the consequences of a changing climate will involve efforts of various types including the conservation of affected ecosystems. For this, communities throughout the world will be called on to change habits of land and water use. Many of these changes will emerge from the multilevel governance tools now commonly used for environmental protection. In this article, some tenets of a social psychology of legal innovation are proposed for approaching the psycho-social processes involved in how individuals, groups and communities respond to multilevel governance. Next, how this approach can improve our understanding of community-based conservation driven by legal innovation is highlighted. For this, the macro and micro level processes involved in the implementation of the European Natura 2000 Network of Protected Sites are examined. Finally, some insights gained from this example of multilevel governance through legal innovation will be enumerated as a contribution for future policy making aimed at dealing with climate change consequences.

    In July 2006 a war between Lebanon and Israel resulted in severe environmental damage in Lebanon from Israeli bombing raids. An attack on the Lebanese Jiyyeh Power Plant released 15,000 tons of heavy fuel oil into the Mediterranean Sea. Remarkably, a clean-up operation was effected despite a continued state of war and lack of capacity in the Lebanese government. Civil society environmentalists played a key role in dealing with the pollution and complying with pollution-control legislation. In this study we use Q-methodology to analyse discourses on the effectiveness of pollution legislation during times of conflict using the Jiyyeh oil spill as an example. We interviewed 35 people from eight different stakeholder groups involved in environmental issues. Five distinct discourses were generated covering compensation schemes, need for new legislation, role of stakeholders during wartime and strengthening government ministries. PMID:20018427

    Health sector workers respond to inadequate salaries and working conditions by developing various individual "coping strategies"--some, but not all, of which are of a predatory nature. The paper reviews what is known about these practices and their potential consequences (competition for time, brain drain and conflicts of interest). By and large, governments have rarely been proactive in dealing with such problems, mainly because of their reluctance to address the issue openly. The effectiveness of many of these piecemeal reactions, particularly attempts to prohibit personnel from developing individual coping strategies, has been disappointing. The paper argues that a more proactive approach is required. Governments will need to recognize the dimension of the phenomenon and systematically assess the consequences of policy initiatives on the situation and behaviour of the individuals that make up their workforce.

    Background Illicit drug markets are a key component of the risk environment surrounding injection drug use. However, relatively few studies have explored how injection drug users’ (IDUs) involvement in drug dealing shapes their experiences of drug market-related harm. This exploratory qualitative study aims to understand IDUs’ dealing activities and roles, as well as the perceived benefits and risks related to participation in illicit drug markets, including experiences of drug market violence. Methods Ten IDUs with extensive involvement in drug dealing activities were recruited from the Vancouver Injection Drug User Study (VIDUS) and participated in semi-structured qualitative interviews, which elicited discussion of experiences dealing drugs, perceived benefits and hazards related to dealing, and understandings of drug market violence. Results Participant's involvement in drug market activities included corporate sales, freelance or independent sales, and opportunistic sales termed “middling” as well as drug market-related hustles entailing selling bogus drugs and robbing dealers. Participants primarily dealt drugs to support their own illicit drug use, and we found that arrest and criminal justice involvement, hazards stemming from drug debts, and drug market-related violence were key risks related to dealing activities. Conclusion The challenges of managing personal consumption while selling drugs exacerbates the hazards associated with drug dealing. Efforts to address drug dealing among IDUs should consider both drug dependency and the material conditions that propel drug users towards dealing activities. Interventions should explore the potential of combining enhanced drug treatment programs with low threshold employment and alternative income generation opportunities. PMID:23664788

    1998-06-01

    During the 1930s the United States Government poured significant funds into malaria control, via a variety of New Deal agencies. These projects were largely confined to drainage of mosquito-producing wetlands. Malaria had diminished significantly by the early 1940s, and this paper queries whether that reduction was due to the control projects of the thirties, and, if so, whether such projects should be a model for the current developing world, where malaria is a growing problem today. Malaria statistics from the 1930s and 1940s are unreliable, making this assessment, from the outset, complex. Further, the so-called "malaria projects" from the 1930s were, in fact, poorly planned "make-work" enterprises promoted by the Works Projects Administration and its ilk for the creation of unskilled, ditch-digging jobs. The drainage work lacked the oversight of competent engineers (many of them proving, in fact, that water wont's run uphill), and little of the work had permanent impact as the ditches were not maintained. Further, the work was not necessarily concentrated in malarious areas, since the unemployed's distribution did not overlap that of greatest mosquito density. Of the conflicting goals--unemployment relief and malaria control--the former consistently dominated the latter. The results were predictable. The author suggests that the depopulation of the rural south in the late 1930s had more of an impact (albeit indirect and unintended) on the malaria rates than did the large sums spent allegedly for the purpose of malaria control.

    2002-05-01

    The treatment of uncertainties associated with modeling has recently attracted significant attention. The methodology and guidance for parameter uncertainty is fairly well developed, and quantitative tools such as Monte-Carlo modeling are often recommended to reduce or more carefully assess the impact of parameter uncertainty on modeled results. However, the issue of model uncertainty is still rarely addressed during the practical application of risk assessment. The use of several alternative models to derive a range of modeled risks is one of a few available techniques. However, the issue of what we call "modeler uncertainty," originating from the assessors' subjective interpretation of the problem at hand, is often overlooked. Work presented here discusses several case studies in which the relative influence of model and "modeler" on the predictions of several multimedia models was quantified. The study employed results from the Fruit and Forest Working Groups, which were created under the International Atomic Energy Agency (IAEA) BIOMASS program. These working groups conducted the model-model and model-data intercomparisons reviewed in this study under several scenarios developed by the IAEA, in which fifteen models were evaluated. The majority of these models were developed by government agencies for regulatory assessment of radionuclide concentrations in terrestrial and agricultural ecosystems, but their modeling approaches were quite different, with the degree of treatment of temporal processes being one of the major factors varying across the models. Scenarios were developed for several contamination sources, including both acute and chronic atmospheric deposition of radionuclides, and the disposal of radioactive waste in trenches. The calculation endpoints were time series of radionuclide concentrations in soil and biota. The greatest uncertainty was found to result from "modeler uncertainty." In scenarios whose details were unfamiliar to modelers, the

    Background Diagnostic reasoning in primary care setting where presented problems and patients are mostly unselected appears as a complex process. The aim was to develop a questionnaire to describe how general practitioners (GPs) deal with uncertainty to gain more insight into the decisional process. The association of personality traits with medical decision making was investigated additionally. Methods Raw items were identified by literature research and focus group. Items were improved by interviewing ten GPs with thinking-aloud-method. A personal case vignette related to a complex and uncertainty situation was introduced. The final questionnaire was administered to 228 GPs in Germany. Factorial validity was calculated with explorative and confirmatory factor analysis. The results of the Communicating and Dealing with Uncertainty (CoDU) – questionnaire were compared with the scales of the ‘Physician Reaction to Uncertainty’ (PRU) questionnaire and with the personality traits which were determined with the Big Five Inventory (BFI-K). Results The items could be assigned to four scales with varying internal consistency, namely ‘communicating uncertainty’ (Cronbach alpha 0.79), ‘diagnostic action’ (0.60), ‘intuition’ (0.39) and ‘extended social anamnesis’ (0.69). Neuroticism was positively associated with all PRU scales ‘anxiety due to uncertainty’ (Pearson correlation 0.487), ‘concerns about bad outcomes’ (0.488), ‘reluctance to disclose uncertainty to patients’ (0.287), ‘reluctance to disclose mistakes to physicians’ (0.212) and negatively associated with the CoDU scale ‘communicating uncertainty’ (−0.242) (p<0.01 for all). ‘Extraversion’ (0.146; p<0.05), ‘agreeableness’ (0.145, p<0.05), ‘conscientiousness’ (0.168, p<0.05) and ‘openness to experience’ (0.186, p<0.01) were significantly positively associated with ‘communicating uncertainty’. ‘Extraversion’ (0.162), ‘consciousness’ (0.158) and

    1993-10-01

    If TSDFs are the most controversial elements of hazardous waste regulation, then dealing with a host community is the most delicate issue in facility siting. In the last 20 years, public perception of hazardous waste treatment facilities, especially incinerators, has turned from naivete about waste management technologies to a general distrust of incinerator operators and government regulators. The political and emotional clout wielded by citizens and environmental activists can derail any incinerator developer's plans, even when industry and regulators support the project. Public resistance results from anxiety about the environment, low confidence in science and government, and a feeling of powerlessness over local events. Both RCRA and Superfund initially contained provisions for public comment but provided few statutory toeholds for citizens to obtain legal redress of grievances in court. Congress strengthened public participation opportunities when RCRA and Superfund were reauthorized in the 1980s. Since then, the public has become major player in the waste treatment business. Citizens group, often in combination with environmental organizations have waged aggressive public relations campaigns and used legal actions to defeat incinerator-siting proposals.

    Modern research projects on national, European and international level are challenged by an increasing requirement of inter and trans-disciplinarily, societal relevance and educational outreach as well as market oriented applications. In particular, to be successful in European research in the frame of HORIZON 2020, the EU Framework Programme for Research and Innovation, it is crucial that relatively large international research consortia involve academic and non-academic partners, NGOs, private and non-private institutions as well as industrial companies. For the management and organisation of such consortia coordinators have to deal with significant differences between multi-national and multi-sectorial administrations and research environments, in order to secure a successful implementation of the project. This often costs research and non-academic partners tremendous efforts, not to say excessive demands. Based on the experiences made in the frame of an Innovative Training Network (ITN) project within the HORIZON 2020 Marie Skłodowska-Curie Actions, this presentation identifies organisational pitfalls and major challenges of the project management for European funded research involving multi-national academic and non-academic research partners. Possible strategies are discussed to circumvent and avoid conflicts already at the beginning of the project.

    ABSTRACT Proper kinetochore recruitment and regulation of dynein and the Mad1–Mad2 complex requires the Rod–Zw10–Zwilch (RZZ) complex. Here, we describe rodZ3, a maternal-effect Drosophila mutation changing a single residue in the Rough Deal (Rod) subunit of RZZ. Although the RZZ complex containing this altered subunit (denoted RZ3ZZ) is present in early syncytial stage embryos laid by homozygous rodZ3 mothers, it is not recruited to kinetochores. Consequently, the embryos have no spindle assembly checkpoint (SAC), and syncytial mitoses are profoundly perturbed. The polar body (residual meiotic products) cannot remain in its SAC-dependent metaphase-like state, and decondenses into chromatin. In neuroblasts of homozygous rodZ3 larvae, RZ3ZZ recruitment is only partially reduced, the SAC is functional and mitosis is relatively normal. RZ3ZZ nevertheless behaves abnormally: it does not further accumulate on kinetochores when microtubules are depolymerized; it reduces the rate of Mad1 recruitment; and it dominantly interferes with the dynein-mediated streaming of RZZ from attached kinetochores. These results suggest that the mutated residue of rodZ3 is required for normal RZZ kinetochore recruitment and function and, moreover, that the RZZ recruitment pathway might differ in syncytial stage embryos and post-embryonic somatic cells.

    Introduction: Bioterrorism is a worldwide problem and has been the focus of attention during recent decades. There is no precise information on the knowledge, attitude, and preparedness of Iranian Red Crescent volunteers in dealing with bioterrorism. Therefore, the present study aimed to evaluate the above-mentioned parameters in Mahabad Red Crescent Society volunteers. Methods: In this prospective cross-sectional study, the knowledge of 120 volunteers was evaluated and rated as poor, moderate, and good. In addition, attitude of the volunteers and preparedness of Mahabad Red Crescent Society was rated as inappropriate and appropriate using a questionnaire. Results: The mean age of volunteers was 32.0 ± 8.2 years (62.5% male). 2 (1.7%) volunteers had good knowledge while 94 (78.3%) had no knowledge regarding bioterrorist attack management. Only 1 (0.8%) volunteer had appropriate attitude and 6 (5.0%) stated their preparedness for being sent out to the crisis zone. 116 volunteers (96.7%) indicated that Mahabad Red Crescent Society has an inappropriate level of preparedness to encounter bioterrorist attacks. Conclusion: The findings of the present study showed poor knowledge and inappropriate attitude of Mahabad Red Crescent Society volunteers in encountering probable bioterrorist attacks. Furthermore, the Red Crescent Society of this town had an inappropriate level of preparedness in the field of bioterrorism from the viewpoint of the studied volunteers. PMID:26862544

    This paper analyzes the inherent contradictions that exist in most of the conventional approaches dealing with airplane hijacking, and presents a completely different approach, employing innovative technological and operational solution. The suggested techno-operational concept is derived from the Systematic Inventive Thinking (SIT) methodology which enforces the problem solver to search for a solution under a few constraining rules -- causing the solution (if found) to be very cost effective. The basic problem that arises from most existing conventional concepts is their very poor cost effectiveness. Passengers, airport operators and aviation companies are all forced to invest on a continual basis, huge amounts of resources and time in order to prevent a hijacking event. The "Auto Immune" concept, discussed here, is based upon enlisting the passengers (in a case of "Hijacking Event" only) to foil the event successfully by releasing, in real-time, a very effective "One-time Non-Lethal Apparatus" (ONLA). This new paradigm changes dramatically the balance of power in favor of the "good guys", and the few hijackers will be neutralized at low risk to the passengers and the aircraft. The detailed technological and operational concept is described, including: operation modes of ONLA, location, release method, safety issues, psychological and legal issues, etc.

  15. Personal Prayer in Patients Dealing with Chronic Illness: A Review of the Research Literature

    PubMed Central

    Jors, Karin; Baumann, Klaus

    2015-01-01

    Background. Prayer is commonly used among patients for health purposes. Therefore, this review focused on three main questions: (1) why do people turn to prayer in times of illness?, (2) what are the main topics of their prayers?, and (3) how do they pray? Method. We undertook a systematic review of the literature by searching the databases PubMed, Medline, and PsycINFO. The following inclusion criteria were used: (1) participants in the study were patients dealing with an illness, (2) the study examined the use of private rather than intercessory prayer, and (3) the content and purpose of prayer rather than its effects were investigated. Results. 16 articles were included in the final review. Participants suffered from a variety of chronic diseases, mostly cancer. Five main categories for the reasons and topics of prayer were found: (1) disease-centered prayer, (2) assurance-centered prayer, (3) God-centered prayer, (4) others-centered prayer, and (5) lamentations. Among these, disease-centered prayer was most common. Conclusions. Although most patients with chronic diseases do pray for relief from their physical and mental suffering, the intention of their prayers is not only for healing. Rather, prayer can be a resource that allows patients to positively transform the experience of their illness. PMID:25815041

  16. Forrester Blanchard Washington and his advocacy for African Americans in the new deal.

    PubMed

    Barrow, Frederica H

    2007-07-01

    Forrester Blanchard Washington (1887-1963) was an African American social work pioneer recruited to the first New Deal administration of Franklin Delano Roosevelt as director of Negro Work in the Federal Emergency Relief Administration. This role gave Washington a platform from which to object strenuously to the development of social policies that were predisposing African Americans to chronic dependence on welfare programs instead of creating equal opportunities for employment. Washington's policy analysis and recommendations represent social work's advocacy for equal employment opportunity long before the related civil rights legislation in the 1960s. An analysis is offered to explain Washington's decision to abort his federal career when the political agenda of the Roosevelt administration began to conflict with his values and professional goals. His actions are exemplary of resignation in protest--an aspect of advocacy more often discussed than used. This article is based on Washington's writings and materials found in the National Archives and Records Administration at College Park, Maryland. PMID:17850028

  17. Alternative approaches to dealing with respondent uncertainty in contingent valuation: a comparative analysis.

    Several strategies have been proposed to deal with response uncertainty in contingent valuation. One approach, often applied to address issues of hypothetical bias, recodes and/or reweights responses according to stated levels of certainty but so far few analyses compare alternative recoding and reweighting strategies. We explore the choice among alternative strategies that exploit a numerical certainty scale obtained from a follow-up to the payment question in a valuation survey about a whale conservation program. Two novel variations of previously followed approaches perform best on our dataset in terms of the efficiency of estimates. The first one uses an exponential transformation of the numerical certainty scale as a weight in the willingness to pay regression. The other one is based on constructing a continuous willingness to pay variable with the highly certain "yes" and "no" original responses to the payment question as extreme values and with mid-point values that correspond to the original "don't know" responses. We find, though, that the effect of using different treatment strategies on mean willingness to pay is rarely statistically significant and we fail to detect a consistent effect on the efficiency of the estimation regardless of the strategy applied.

    We report the case of a Palestinian American psychologist trained to work with psychologically traumatized patients, who consulted with one World Health Organization mental health practitioner assisting the people of Gaza during the Israeli invasion of December 2008. We describe the unresolved tension experienced by the consulting provider, between feelings of helplessness and horror associated with the attack and the drive to assist a client, in this case a colleague, a drive that characterizes the helping professions generally, and discuss ways to improve healthcare providers' abilities to deal with trauma work. Our goal is to call attention to one overlooked health effect of the continuing military occupation of the Palestinian territories (oPT), that is, its impact on healthcare providers, by giving voice to these providers, and to elaborate on the limitations of existing categories and theoretical frameworks to conceptualize and address trauma work in the oPT and similar settings. This article is part of a broader project examining the implications of the ongoing military occupation of the Palestinian territories for health inequalities, health services, and public health infrastructure.

    Violence is increasing worldwide mainly among the most socially vulnerable groups such as women, elderly people, children and adolescents. In addition to the justice sector, many other areas and workers are involved and they are becoming even more important for addressing violence. One such area is the health sector. This article aims to identify the creative potential of videos that aim to tackle issues involving domestic violence against children which are categorized based on generation (age) and gender. A search was conducted between 2013 and 2014 on official sites and video channels of institutions that deal with child-related topics. We used the webQDA software to conduct our analysis and for reference purposes we used "Generation" and "Gender" as categories. We collected 40 video campaigns, of which ten were analyzed qualitatively. Upon analyzing complete scenes and parts of scenes we were able to see both inter/intra -generational and inter/intra-gender violence and its consequences for children. The videos allowed for critical reflections to be made on the educational processes and training used to combat violence against children in the context of "Generations" and "Genders". PMID:27557008

    Sooner or later, the Astronomy 101 or astrobiology instructor encounters a student who disbelieves, or is at least skeptical of, factual information presented about the age of the Earth, the age of the universe, astrobiology, or biological evolution. Understanding the evidence and current state of our scientific knowledge about these subjects is important for the Astro 101 instructor faced with individual skeptical students. This understanding is also vitally important for those Astro 101 students who are future teachers and have preconceptions that could have a major impact on the thinking of large numbers of future students. This article contains a summary of different types of pseudoscientific beliefs that students have and suggests ways to approach these subjects so that skeptical learners are more likely to consider the facts presented in the astronomy class. Also included are some useful approaches for dealing with the more recent creationist ideas and tactics, such as "irreducible complexity" and "intelligent design"--especially now that President George W. Bush has expressed support for intelligent design. An appendix catalogs the different forms of creationism and lists some typical questions that their proponents might ask in class, along with suggested answers.

    Since the order in the diatomic potential (or vibrational energy) expansion may be different from state to state, the algebraic method (AM) proposed by Sun et al. (J Mol Spectrosc 2002; 215: 93-105) is modified to adapt to the individual nature of different energy expansions by changing an original fixed order to a flexible one. The modified AM with a flexible order can be used to deal with the possible “butterfly effect” that may happen in spectroscopic computations, and it is applied to study the full vibrational spectra {Eυ} and the dissociation energies De for L7i2-2Σg+, K2-3Πg, Cs2-3∑g+, KLi-X∑, and RbCs-XΣ electronic states. The results not only reproduce the known experimental vibrational energies, but also correctly predict the dissociation energies and all unknown energies that have not been obtained for these electronic states using the original AM. These facts demonstrate that the modified AM are good for many more diatomic systems by using the proper order of each corresponding diatomic state.

    The medical practice of declawing has received much political debate over the past few years. Yet, empirical and theoretical research on how this practice is maintained and the ethical positions of those who actually participate in this work is lacking. Drawing from 9 months of ethnographic fieldwork in a feline-specific veterinary hospital and open-ended interviews with veterinarians and staff, this study examines veterinary staff members' attitudes toward, and strategies for, dealing with the medical practice of declawing. Specifically, findings show that a number of staff felt uncomfortable with their participation in onychectomy (declawing) and relied heavily on organizational support structures to cope both with these feelings and the moral ambiguity about the practice. Relying on these structures, the veterinarians and their staff are able simultaneously to define felines as subjects worthy of respect for their quality of life, protect their own self-identity as people who work toward the best interest of animals, and paradoxically support action toward felines that they find morally objectionable.

    Background: The management of large animals during disasters and emergencies creates difficult operational environments for responders. The aims of this study were to identify the exact challenges faced by Australian emergency response personnel in their interactions with large animals and their owners, and to determine the readiness for large animal rescue (LAR) in Australia. Methods: A survey tool collected the views and experiences of a broad cross section of emergency services personnel operating across Australia and across all hazards. Data were collected from 156 responders including Australian emergency services personnel, emergency managers such as federal agricultural departments, and local government. Results: Overall, many of the respondents had serious concerns, and felt that there were significant issues in relation to LAR in Australia. These included the coordination of emergency care for animals, physical management of large animals, inter-agency coordination, and dealing with animal owners. Very few respondents had received any formal training in LAR, with an overwhelming majority indicating they would attend formal training if it were made available. Discussion: Results help to guide the development of evidence-informed support tools to assist operational response and community engagement, and the production of professional development resources.

    2015-01-01

    This review presents an overview of the successes and challenges currently faced in alpha radionuclide therapy. Alpha particles have an advantage in killing tumour cells as compared to beta or gamma radiation due to their short penetration depth and high linear energy transfer (LET). Touching briefly on the clinical successes of radionuclides emitting only one alpha particle, the main focus of this article lies on those alpha-emitting radionuclides with multiple alpha-emitting daughters in their decay chain. While having the advantage of longer half-lives, the recoiled daughters of radionuclides like 224Ra (radium), 223Ra, and 225Ac (actinium) can do significant damage to healthy tissue when not retained at the tumour site. Three different approaches to deal with this problem are discussed: encapsulation in a nano-carrier, fast uptake of the alpha emitting radionuclides in tumour cells, and local administration. Each approach has been shown to have its advantages and disadvantages, but when larger activities need to be used clinically, nano-carriers appear to be the most promising solution for reducing toxic effects, provided there is no accumulation in healthy tissue.

    Uncertainty is an increasingly important concern when trying to manage complex systems of interrelated natural resources. Scientific knowledge or necessary information may be lacking or incomplete. Additionally, the multiple and interdependent users of those resources may diverge in defining what really is at stake. When they frame issues in very different ways, ambiguity results, i.e., the existence of two or more equally plausible interpretation possibilities. Environmental management in these conditions implies a shift in attention from solving clearly delineated problems to continuous negotiating and tuning between different actors and expertise domains. This requires dealing with the frame differences in a reciprocal way by mutually acknowledging frames and connecting them. Some or all parties will have to revise, enlarge or reframe the way they relate to the issues and to each other, in order to support mutual understanding and common action. The contribution of experts does not consist then in providing total predictability nor in predefining issues and solutions, but in supporting a joint learning and negotiation process among different actors and in feeding this process with relevant information. Behavioural simulations may play an important function to stimulate multi-actor learning and negotiation processes. PMID:16304943

    Host use by herbivores is largely determined by host properties such as nutrient content and chemical defence against foragers. The impacts of these attributes on a herbivore may largely depend on its life cycle stage. Lichen species are known to differ in nutritional quality and level of chemical defence and, consequently, vary as fodder for herbivores. The aim of this study was to explore the impact of several lichen species and the presence of their secondary metabolites on their use as hosts by a specialist lichen-feeder, Cleorodes lichenaria. This study also addressed, for the first time, how a specialist lichen-feeder deals with different lichen secondary metabolites. In the beginning of their development, larvae grew better on Xanthoria parietina than on the other host lichens, whereas older larvae grew best on Ramalina fraxinea. Lichen secondary chemicals in R. fraxinea and Parmelia sulcata hindered larval growth in the beginning but after 75 days lichen secondary chemicals had no impact on the mass of larvae. Physodic acids in Hypogymnia physodes were lethal to larvae. In general, larvae metabolized 70-95% of ingested lichen secondary chemicals and the rest of these were excreted in frass. Lichen secondary metabolites in P. sulcata restrict and in H. physodes prevent their use as a host for C. lichenaria larvae. Our main finding, the ability of larvae to metabolize several lichen secondary metabolites, indicates digestive adaptation to these chemicals. No signs of sequestration of these chemicals were found.

    The Institut Municipal d'Assistència Sanitària (IMAS) is a health care organization in Barcelona, comprising two general hospitals, a psychiatric hospital, a surgical clinic, a geriatric center, some primary care clinics, and a research institute. Since 1984, IMAS has been engaged in creating a multicenter integrated hospital information system (IMASIS). Currently, IMASIS offers the possibility to manage administrative data, laboratory results, pathology and cytology reports, radiology reports, and pharmacy inpatient orders; it also shares this information on-line among IMAS centers. IMASIS users may also work with a word processor, a spreadsheet, a database, or a statistical package and have access to MEDLINE. A second phase of IMASIS development began in December 1993 focused on clinical information management. The goal was to move towards an integrated multimedia medical record [1]. As a first step, the implementation experiences of the most advanced hospital information systems around the world were studied. Some of these experiences detected behavioral, cultural, and organizational factors [2] as the main sources of delay, or even failure, in HIS projects. A preliminary analysis to define such factors, assess their potential impact, and introduce adequate measures to deal with them seemed unavoidable before structuring of the project. In our approach to physician attitudes analysis, two survey techniques were applied. First, every hospital service head was contacted to schedule an interview, with either a service representative or a group of staff physicians and residents. The aim was to provide detailed information about project objectives and collect personal opinions, problems encountered in the current HIS, and specific needs of every medical and surgical specialty (including imaging needs). Every service head was asked to distribute a questionnaire among all clinicians, which assessed frequency of use of IMASIS current applications, user's satisfaction

    2014-09-01

    This paper presents a water resources management strategy developed by the Brazilian National Water Agency (ANA) to cope with the conflicts between water users in the Verde Grande River basin, located at the southern border of the Brazilian semi-arid region. The basin is dominated by water-demanding fruit irrigation agriculture, which has grown significantly and without adequate water use control, over the last 30 years. The current water demand for irrigation exceeds water availability (understood as a 95 % percentile of the flow duration curve) in a ratio of three to one, meaning that downstream water users are experiencing more frequent water shortages than upstream ones. The management strategy implemented in 2008 has the objective of equalizing risk for all water users and consists of a set of rules designed to restrict water withdrawals according to current river water level (indicative of water availability) and water demand. Under that rule, larger farmers have proportionally larger reductions in water use, preserving small subsistence irrigators. Moreover, dry season streamflow is forecasted at strategic points by the end of every rainy season, providing evaluation of shortage risk. Thus, water users are informed about the forecasts and corresponding restrictions well in advance, allowing for anticipated planning of irrigated areas and practices. In order to enforce restriction rules, water meters were installed in all larger water users and inefficient farmers were obligated to improve their irrigation systems' performance. Finally, increases in irrigated area are only allowed in the case of annual crops and during months of higher water availability (November to June). The strategy differs from convectional approached based only on water use priority and has been successful in dealing with natural variability of water availability, allowing more water to be used in wet years and managing risk in an isonomic manner during dry years.

  11. Inappropriate publication of trial results and potential for allegations of illegal share dealing.

    1993-04-24

    There is increasing evidence of fraud in clinical research, and one aspect concerns trading in pharmaceutical company shares by people who may have confidential information about the results of clinical trials. Plainly this has implications for honest investigators, who may find themselves exposed to such allegations. In this paper Dr D S Freestone and Mr H Mitchell, QC, identify three interlinked issues which they think underlie the potential for these allegations. They are pressure for premature or inappropriate communication of research results; trading in pharmaceutical company shares by academic clinical investigators; and the possibility that clinical investigators might succumb to temptation. Dr Freestone and Mr Mitchell suggest that whenever possible results of clinical studies should be published in appropriate medical journals without prior public disclosure. This conflicts with Stock Exchange rules, which require that price sensitive information should be published at the earliest opportunity and preclude priority of publication in medical journals. Freestone and Mitchell believe that rarely rapid public disclosure is acceptable if it is to protect patients' interests but that it must not prejudice publication in the medical or scientific press. When rapid public disclosure is needed, they say, every attempt should be made to inform prescribers before patients. Dr Freestone and Mr Mitchell warn that academic clinical investigators who have access to unpublished price sensitive information about pharmaceutical companies whose shares they trade in will almost certainly be in breach of the Company Securities (Insider Dealing) Act 1985. Furthermore, disclosing such information to third parties, they say, exposes those people also to potential criminal liability. Freestone and Mitchell advise that when potential for allegations of conflict of interest exists clinical investigators should consider declaring their position to ethics committees and any

    The date of March 31, 2015, following the Law 81/2014, has marked a historical transition with the final closure of the six forensic psychiatric hospitals in Italy. This law identifies a new pathway of care that involves small-scale high therapeutic profile facilities (Residenze per la Esecuzione della Misura di Sicurezza, REMS) instead of the old forensic psychiatric hospitals. The Law promotes a new recovery-oriented rehabilitation approach for the persons with mental disorders who committed a criminal offence, but lack criminal responsibility and deemed as socially dangerous. After a brief description of what happens abroad, this article highlights the positive aspects of the law that, as a whole, has to be considered innovative and unavoidable. The main debated problems are also reviewed, including the lack of changes to the Criminal Code; the improper equation between insanity and mental illness and social dangerousness; the evaluation of "socially dangerousness", based solely on "subjective qualities" of the person, assessed out of his/her context, without paying attention to family and social conditions suitable for discharge; the expensive implementation of the REMS, mainly based on security policies and less on care and rehabilitation, the delay in their construction, and the search for residential alternatives structures; the uncertain boundaries of professional responsibility. Finally, several actions are suggested that can support the implementation of the law: information programs addressed to the general population; training activities for mental health professionals; systematic monitoring and evaluation of the outcomes of the care provided to the forensic psychiatric population; implementation of Agreement Protocols and a better cooperation with the judiciary. Scientific societies dealing with psychosocial rehabilitation need to be involved in such issues relating to the identification of the best care and rehabilitation pathways, which should be

    2010-03-01

    High-throughput biotechnologies, such as gene expression microarrays or mass-spectrometry-based proteomic assays, suffer from frequent missing values due to various experimental reasons. Since the missing data points can hinder downstream analyses, there exists a wide variety of ways in which to deal with missing values in large-scale data sets. Nowadays, it has become routine to estimate (or impute) the missing values prior to the actual data analysis. After nearly a decade since the publication of the first missing value imputation methods for gene expression microarray data, new imputation approaches are still being developed at an increasing rate. However, what is lagging behind is a systematic and objective evaluation of the strengths and weaknesses of the different approaches when faced with different types of data sets and experimental questions. In this review, the present strategies for missing value imputation and the measures for evaluating their performance are described. The imputation methods are first reviewed in the context of gene expression microarray data, since most of the methods have been developed for estimating gene expression levels; then, we turn to other large-scale data sets that also suffer from the problems posed by missing values, together with pointers to possible imputation approaches in these settings. Along with a description of the basic principles behind the different imputation approaches, the review tries to provide practical guidance for the users of high-throughput technologies on how to choose the imputation tool for their data and questions, and some additional research directions for the developers of imputation methodologies.

    2016-05-01

    This paper is of methodological nature, and deals with the foundations of Risk Assessment. Several international guidelines have recently recommended to select appropriate/relevant Hazard Scenarios in order to tame the consequences of (extreme) natural phenomena. In particular, the scenarios should be multivariate, i.e., they should take into account the fact that several variables, generally not independent, may be of interest. In this work, it is shown how a Hazard Scenario can be identified in terms of (i) a specific geometry and (ii) a suitable probability level. Several scenarios, as well as a Structural approach, are presented, and due comparisons are carried out. In addition, it is shown how the Hazard Scenario approach illustrated here is well suited to cope with the notion of Failure Probability, a tool traditionally used for design and risk assessment in engineering practice. All the results outlined throughout the work are based on the Copula Theory, which turns out to be a fundamental theoretical apparatus for doing multivariate risk assessment: formulas for the calculation of the probability of Hazard Scenarios in the general multidimensional case (d≥2) are derived, and worthy analytical relationships among the probabilities of occurrence of Hazard Scenarios are presented. In addition, the Extreme Value and Archimedean special cases are dealt with, relationships between dependence ordering and scenario levels are studied, and a counter-example concerning Tail Dependence is shown. Suitable indications for the practical application of the techniques outlined in the work are given, and two case studies illustrate the procedures discussed in the paper.

    Films that feature characters with cancer have become a familiar sight for movie-goers. 148 movies treating tumors were selected, produced all over the world since the Thirties, in which cancer had "prompt", "relevant", or "plot" character. In order to clearly understand each film's peculiar message about cancer, we recollected data such as genealogy, year and country of production, main characters' age and gender, and kind of tumor. Movies deal with cancer through very relevant questions, as well as themes and contexts that have great influence on oncologist's mind and consciousness. Specially in recent years, films have tackled some of the most important issues around cancer, such as his epidemiology and environmental causes; the economic implications of therapies; the management of symptoms and side effects; the psychological dynamics; the care toward the ending of life. The most frequent treatment mentioned in the movies was chemotherapy followed by antalgic therapy. Very often the ill person on the screen doesn't get over the disease and his death is somehow useful to the plot's outcome. This pattern is so strongly standardized that it persists in spite of real progress of treatments. Movies use disease, and other tragedies, as a dramatic device, and since drama is what we expect of the medium, should we be concerned that there is a gap between fiction and reality? Movies represent an essential step of educational process, but their potential has been fully exploited only in recent times. By watching movies on cancer, oncologists could become more conscious of problems they are already facing in the therapeutic setting: cancer and sexuality, the relationship between the ill person and the medical staff, side effects of therapies. Some films simply make us reflect upon the meaning of life and death. This is useful for the sharing of cancer care, from personal or familiar problems to issues of collective relevance.

    The Government of Canada nuclear legacy liabilities have resulted from 60 years of nuclear research and development (R and D) carried out on behalf of Canada by the National Research Council (1944 to 1952) and Atomic Energy of Canada Limited (AECL, 1952 to present). These liabilities are largely located at AECL research sites, and consist of shutdown research buildings (including several prototype and research reactors), a wide variety of buried and stored wastes, and contaminated lands. The shutdown buildings and contaminated lands need to be safely decommissioned to meet federal regulatory requirements, and long-term solutions need to be developed and implemented for management of the wastes. More than half of the liabilities are the result of Cold War activities during the 1940's, 50's and early 60's. The remaining liabilities stem from R and D for medical isotopes and nuclear reactor technology, as well as national science programs. About 70 percent of the liabilities are located at AECL's Chalk River Laboratories (CRL) in Ontario, and a further 20 percent are located at AECL's shutdown Whiteshell Laboratories in Manitoba. The remaining 10 percent relate largely to three shutdown prototype reactors in Ontario and Quebec, which were key to the developmental stage of Canada's CANDU reactor technology. The inventory of legacy waste includes spent fuel, high-level, intermediate-level and low-level solid and liquid radioactive waste, and wastes (largely contaminated soils) from site clean-up work across Canada. Most of the wastes are in raw, unconditioned form, and limited characterization information is available for the wastes generated in past decades. In many cases unique and potentially costly solutions will be required to recover, handle and process the wastes. In conclusion: the Government of Canada has initiated a program to deal with nuclear legacy liabilities dating back to the Cold War and the birth of nuclear technologies and medicine in Canada.

  1. Transparency--"Deal or no deal"?

    PubMed

    Lutz, Sandy

    2007-01-01

    In the United States, transparency is becoming an ideal worthy of Mom and apple pie, like quality in healthcare. Physicians, payers, hospitals, business associations, and organizations representing patients have all chimed in expressing support. At the local, state, and national levels a variety of transparency initiatives are under way. How will transparency affect the healthcare industry? Transparency could profoundly change today's balance of power, for it is about information, and information is power. As employers push more cost sharing to workers, hospitals and health systems will have to construct a pricing structure that is meaningful to consumers. What are providers to do? To be successful with this new demand, providers should make sure they are making quality information as well as pricing information available to consumers. They will have to know the market, know what their own prices mean, consider the customer, and reengineer business processes around the patient rather than around the billing side of business.

  2. Dealing with varying detection probability, unequal sample sizes and clumped distributions in count data.

    Temporal variation in the detectability of a species can bias estimates of relative abundance if not handled correctly. For example, when effort varies in space and/or time it becomes necessary to take variation in detectability into account when data are analyzed. We demonstrate the importance of incorporating seasonality into the analysis of data with unequal sample sizes due to lost traps at a particular density of a species. A case study of count data was simulated using a spring-active carabid beetle. Traps were 'lost' randomly during high beetle activity in high abundance sites and during low beetle activity in low abundance sites. Five different models were fitted to datasets with different levels of loss. If sample sizes were unequal and a seasonality variable was not included in models that assumed the number of individuals was log-normally distributed, the models severely under- or overestimated the true effect size. Results did not improve when seasonality and number of trapping days were included in these models as offset terms, but only performed well when the response variable was specified as following a negative binomial distribution. Finally, if seasonal variation of a species is unknown, which is often the case, seasonality can be added as a free factor, resulting in well-performing negative binomial models. Based on these results we recommend (a) add sampling effort (number of trapping days in our example) to the models as an offset term, (b) if precise information is available on seasonal variation in detectability of a study object, add seasonality to the models as an offset term; (c) if information on seasonal variation in detectability is inadequate, add seasonality as a free factor; and (d) specify the response variable of count data as following a negative binomial or over-dispersed Poisson distribution.

  10. The crossing statistic: dealing with unknown errors in the dispersion of Type Ia supernovae

    SciTech Connect

    Shafieloo, Arman; Clifton, Timothy; Ferreira, Pedro E-mail: tclifton@astro.ox.ac.uk

    2011-08-01

    We propose a new statistic that has been designed to be used in situations where the intrinsic dispersion of a data set is not well known: The Crossing Statistic. This statistic is in general less sensitive than χ{sup 2} to the intrinsic dispersion of the data, and hence allows us to make progress in distinguishing between different models using goodness of fit to the data even when the errors involved are poorly understood. The proposed statistic makes use of the shape and trends of a model's predictions in a quantifiable manner. It is applicable to a variety of circumstances, although we consider it to be especially well suited to the task of distinguishing between different cosmological models using type Ia supernovae. We show that this statistic can easily distinguish between different models in cases where the χ{sup 2} statistic fails. We also show that the last mode of the Crossing Statistic is identical to χ{sup 2}, so that it can be considered as a generalization of χ{sup 2}.

  12. The method of belief scales as a means for dealing with uncertainty in tough regulatory decisions.

    SciTech Connect

    Pilch, Martin M.

    2005-10-01

    Modeling and simulation is playing an increasing role in supporting tough regulatory decisions, which are typically characterized by variabilities and uncertainties in the scenarios, input conditions, failure criteria, model parameters, and even model form. Variability exists when there is a statistically significant database that is fully relevant to the application. Uncertainty, on the other hand, is characterized by some degree of ignorance. A simple algebraic problem was used to illustrate how various risk methodologies address variability and uncertainty in a regulatory context. These traditional risk methodologies include probabilistic methods (including frequensic and Bayesian perspectives) and second-order methods where variabilities and uncertainties are treated separately. Representing uncertainties with (subjective) probability distributions and using probabilistic methods to propagate subjective distributions can lead to results that are not logically consistent with available knowledge and that may not be conservative. The Method of Belief Scales (MBS) is developed as a means to logically aggregate uncertain input information and to propagate that information through the model to a set of results that are scrutable, easily interpretable by the nonexpert, and logically consistent with the available input information. The MBS, particularly in conjunction with sensitivity analyses, has the potential to be more computationally efficient than other risk methodologies. The regulatory language must be tailored to the specific risk methodology if ambiguity and conflict are to be avoided.

  14. Tailoring point counts for inference about avian density: dealing with nondetection and availability

    USGS Publications Warehouse

    Johnson, Fred A.; Dorazio, Robert M.; Castellón, Traci D.; Martin, Julien; Garcia, Jay O.; Nichols, James D.

    2014-01-01

    Point counts are commonly used for bird surveys, but interpretation is ambiguous unless there is an accounting for the imperfect detection of individuals. We show how repeated point counts, supplemented by observation distances, can account for two aspects of the counting process: (1) detection of birds conditional on being available for observation and (2) the availability of birds for detection given presence. We propose a hierarchical model that permits the radius in which birds are available for detection to vary with forest stand age (or other relevant habitat features), so that the number of birds available at each location is described by a Poisson-gamma mixture. Conditional on availability, the number of birds detected at each location is modeled by a beta-binomial distribution. We fit this model to repeated point count data of Florida scrub-jays and found evidence that the area in which birds were available for detection decreased with increasing stand age. Estimated density was 0.083 (95%CI: 0.060–0.113) scrub-jays/ha. Point counts of birds have a number of appealing features. Based on our findings, however, an accounting for both components of the counting process may be necessary to ensure that abundance estimates are comparable across time and space. Our approach could easily be adapted to other species and habitats.

    2011-01-01

    Background and aims Many indeterminate plants can have wide fluctuations in the pattern of fruit-set and harvest. Fruit-set in these types of plants depends largely on the balance between source (assimilate supply) and sink strength (assimilate demand) within the plant. This study aims to evaluate the ability of functional–structural plant models to simulate different fruit-set patterns among Capsicum cultivars through source–sink relationships. Methods A greenhouse experiment of six Capsicum cultivars characterized with different fruit weight and fruit-set was conducted. Fruit-set patterns and potential fruit sink strength were determined through measurement. Source and sink strength of other organs were determined via the GREENLAB model, with a description of plant organ weight and dimensions according to plant topological structure established from the measured data as inputs. Parameter optimization was determined using a generalized least squares method for the entire growth cycle. Key Results and Conclusions Fruit sink strength differed among cultivars. Vegetative sink strength was generally lower for large-fruited cultivars than for small-fruited ones. The larger the size of the fruit, the larger variation there was in fruit-set and fruit yield. Large-fruited cultivars need a higher source–sink ratio for fruit-set, which means higher demand for assimilates. Temporal heterogeneity of fruit-set affected both number and yield of fruit. The simulation study showed that reducing heterogeneity of fruit-set was obtained by different approaches: for example, increasing source strength; decreasing vegetative sink strength, source–sink ratio for fruit-set and flower appearance rate; and harvesting individual fruits earlier before full ripeness. Simulation results showed that, when we increased source strength or decreased vegetative sink strength, fruit-set and fruit weight increased. However, no significant differences were found between large-fruited and

    Sea level rise (SLR) projections along the coast of Florida present an enormous challenge for management and conservation over the long term. Decision makers need to recognize and adopt strategies to adapt to the potentially detrimental effects of SLR. Structured decision making (SDM) provides a rigorous framework for the management of natural resources. The aim of SDM is to identify decisions that are optimal with respect to management objectives and knowledge of the system. Most applications of SDM have assumed that the managed systems are governed by stationary processes. However, in the context of SLR it may be necessary to acknowledge that the processes underlying managed systems may be non-stationary, such that systems will be continuously changing. Therefore, SLR brings some unique considerations to the application of decision theory for natural resource management. In particular, SLR is expected to affect each of the components of SDM. For instance, management objectives may have to be reconsidered more frequently than under more stable conditions. The set of potential actions may also have to be adapted over time as conditions change. Models have to account for the non-stationarity of the modeled system processes. Each of the important sources of uncertainty in decision processes is expected to be exacerbated by SLR. We illustrate our ideas about adaptation of natural resource management to SLR by modeling a non-stationary system using a numerical example. We provide additional examples of an SDM approach for managing species that may be affected by SLR, with a focus on the endangered Florida manatee. ?? 2011 U.S. Government.

  18. Space Station: Delays in dealing with space debris may reduce safety and increase costs

    NASA Astrophysics Data System (ADS)

    1992-06-01

    The majority of NASA's current designs for protecting the space station and crew from debris are outdated and its overall debris protection strategy is insufficient. NASA's contractors have designed the station using a 1984 model of the space environment that is obsolete, significantly underestimating the increasing amount of debris that the station will encounter during its 30-year lifetime. In February 1992, NASA directed its space centers to incorporate an updated 1991 model into their designs. However, the agency has not yet made critical decisions on how to implement this change. Preliminary evaluations show that incorporating the 1991 model using currently established safety criteria could entail a major redesign of some components, with significant cost impact and schedule delays. NASA's overall protection strategy for space debris is insufficient. While NASA has concentrated its protection on shielding the space station from small debris and plans to augment this initial shielding in orbit, it has not yet developed designs or studied the cost and operational impact of augmenting its protection with additional shielding. Further, current designs do not provide the capability of warning or protecting the crew from imminent collision with mid-size debris. Finally, although some capabilities exist for maneuvering the station away from large debris, the agency lacks collision-avoidance plans and debris-tracking equipment. In developing a comprehensive strategy to protect the station from the more severe debris environment, NASA cannot avoid some difficult decisions. These decisions involve tradeoffs between how much the agency is willing to pay to protect the station, the schedule delays it may incur, and the risk to station safety it is willing to accept. It is important that these decisions be made before NASA completes its critical design reviews in early 1993. At that time key designs will be made final and manufacturing will begin.

    This paper addresses the problem of how to value health care programmes with different ratios of costs to effects, specifically when taking into account that these costs and effects are uncertain. First, the traditional framework of maximising health effects with a given health care budget is extended to a flexible budget using a value function over money and health effects. Second, uncertainty surrounding costs and effects is included in the model using expected utility. Other approaches to uncertainty that do not specify a utility function are discussed and it is argued that these also include implicit notions about risk attitude. PMID:15678518

  20. Environmental dilemma game to establish a sustainable society dealing with an emergent value system

    2005-01-01

    To induce whether we can obtain a sustainable society by shifting our paradigm from the materialistic to the eco-conscientious, we established a multi-agent simulation model. The model primarily featured a dilemma structure encouraged by a conflict between each agent's private desire to earn more and the need for environmental conservation. Another important feature is that the model has two evolutionary layers. The subordinate layer is a learning system comprised of a finite state machine (FSM) and a genetic algorithm (GA) primarily, which is carried with each individual agent to determine his/her next behavior and how much he/she must earn to maximize an individual fitness function. The supra layer is the so-called value system, the gene pool of which is shared within the society. The value system stipulates an agent's fitness function, which in turn affects the agent's behavior. The value system of each agent was set up to be entirely ego-oriented at the beginning of the simulation episode. A numerical experiment based on the model reveals a scene in which, under a certain condition related to assumptions of the value system, a group of agents undergoes a paradigm shift from the ego-oriented materialism to the eco-conscious sustainable society. The key condition is a latent existence of several values that ultimately lead to sustainability, even though they do not work at all at the beginning of the episode. In terms of the evolutionary game theory, this implies that changing game structure on the way of a simulation episode by transforming the fitness function seems to be much powerful measures for the emergent collective cooperation among the agents than ordinal options to support cooperation. In addition, we made a detailed analysis on how assumed agents have obtained a sustainable value system. Each agent has an individual decision-making process based on the input with a learning mechanism. We focus here on two types of learning system, the finite state

  1. Comparison of Statistical Approaches for Dealing With Immortal Time Bias in Drug Effectiveness Studies.

    In time-to-event analyses of observational studies of drug effectiveness, incorrect handling of the period between cohort entry and first treatment exposure during follow-up may result in immortal time bias. This bias can be eliminated by acknowledging a change in treatment exposure status with time-dependent analyses, such as fitting a time-dependent Cox model. The prescription time-distribution matching (PTDM) method has been proposed as a simpler approach for controlling immortal time bias. Using simulation studies and theoretical quantification of bias, we compared the performance of the PTDM approach with that of the time-dependent Cox model in the presence of immortal time. Both assessments revealed that the PTDM approach did not adequately address immortal time bias. Based on our simulation results, another recently proposed observational data analysis technique, the sequential Cox approach, was found to be more useful than the PTDM approach (Cox: bias = -0.002, mean squared error = 0.025; PTDM: bias = -1.411, mean squared error = 2.011). We applied these approaches to investigate the association of β-interferon treatment with delaying disability progression in a multiple sclerosis cohort in British Columbia, Canada (Long-Term Benefits and Adverse Effects of Beta-Interferon for Multiple Sclerosis (BeAMS) Study, 1995-2008).

    Clinical studies include occurrences of rare variables, like genotypes, which due to their frequency and strength render their effects difficult to estimate from a dataset. Variables that influence the estimated value of a model-based parameter are termed covariates. It is often difficult to determine if such an effect is significant, since type I error can be inflated when the covariate is rare. Their presence may have either an insubstantial effect on the parameters of interest, hence are ignorable, or conversely they may be influential and therefore non-ignorable. In the case that these covariate effects cannot be estimated due to power and are non-ignorable, then these are considered nuisance, in that they have to be considered but due to type 1 error are of limited interest. This study assesses methods of handling nuisance covariate effects. The specific objectives include (1) calibrating the frequency of a covariate that is associated with type 1 error inflation, (2) calibrating its strength that renders it non-ignorable and (3) evaluating methods for handling these non-ignorable covariates in a nonlinear mixed effects model setting. Type 1 error was determined for the Wald test. Methods considered for handling the nuisance covariate effects were case deletion, Box-Cox transformation and inclusion of a specific fixed effects parameter. Non-ignorable nuisance covariates were found to be effectively handled through addition of a fixed effect parameter. PMID:26112250

    This study aimed to identify initiatives for training staff in the municipal healthcare system in Fortaleza, Ceará State, Brazil, to deal with cases of sexual abuse of children and adolescents. The reference for this exploratory study was the training program provided by the municipal government in 2010-2012 for administrators and health professionals in the public healthcare system in Fortaleza. At the time, the issue of sexual abuse was low in the system's training programs, despite recognition of its importance. Federal and State programs have provided input for such training programs in the various municipal health departments. The main strategy was to invest in training for health workers in primary care. Social workers were found to have insufficient training, aggravated by temporary work contracts and high staff turnover. The study suggests the need for training to deal with violence, particularly sexual abuse. PMID:25760175

The main objective here is to discuss problems of framing an intuitively appealing and computationally efficient knowledge base that can adequately represent the indeterminate legal concept of the well-being of the child in the context of continental legal culture and of Polish law in particular. In addition to commonsense reasoning, interpretation of such a concept demands both legal expertise and significant professional knowledge from other domains. PMID:26495435

    Occupancy surveys should be designed to minimise false absences. This is commonly achieved by increasing replication or increasing the efficiency of surveys. In the case of destructive sampling designs, in which searches of individual microhabitats represent the repeat surveys, minimising false absences leads to an inherent trade-off. Surveyors can sample more low quality microhabitats, bearing the resultant financial costs and producing wider-spread impacts, or they can target high quality microhabitats were the focal species is more likely to be found and risk more severe impacts on local habitat quality. We show how this trade-off can be solved with a decision-theoretic approach, using the Millewa Skink Hemiergis millewae from southern Australia as a case study. Hemiergis millewae is an endangered reptile that is best detected using destructive sampling of grass hummocks. Within sites that were known to be occupied by H. millewae, logistic regression modelling revealed that lizards were more frequently detected in large hummocks. If this model is an accurate representation of the detection process, searching large hummocks is more efficient and requires less replication, but this strategy also entails destruction of the best microhabitats for the species. We developed an optimisation tool to calculate the minimum combination of the number and size of hummocks to search to achieve a given cumulative probability of detecting the species at a site, incorporating weights to reflect the sensitivity of the results to a surveyor's priorities. The optimisation showed that placing high weight on minimising volume necessitates impractical replication, whereas placing high weight on minimising replication requires searching very large hummocks which are less common and may be vital for H. millewae. While destructive sampling methods are sometimes necessary, surveyors must be conscious of the ecological impacts of these methods. This study provides a simple tool for

  8. Is it the real deal? Perception of virtual characters versus humans: an affective cognitive neuroscience perspective

    2015-01-01

    Recent developments in neuroimaging research support the increased use of naturalistic stimulus material such as film, avatars, or androids. These stimuli allow for a better understanding of how the brain processes information in complex situations while maintaining experimental control. While avatars and androids are well suited to study human cognition, they should not be equated to human stimuli. For example, the uncanny valley hypothesis theorizes that artificial agents with high human-likeness may evoke feelings of eeriness in the human observer. Here we review if, when, and how the perception of human-like avatars and androids differs from the perception of humans and consider how this influences their utilization as stimulus material in social and affective neuroimaging studies. First, we discuss how the appearance of virtual characters affects perception. When stimuli are morphed across categories from non-human to human, the most ambiguous stimuli, rather than the most human-like stimuli, show prolonged classification times and increased eeriness. Human-like to human stimuli show a positive linear relationship with familiarity. Secondly, we show that expressions of emotions in human-like avatars can be perceived similarly to human emotions, with corresponding behavioral, physiological and neuronal activations, with exception of physical dissimilarities. Subsequently, we consider if and when one perceives differences in action representation by artificial agents versus humans. Motor resonance and predictive coding models may account for empirical findings, such as an interference effect on action for observed human-like, natural moving characters. However, the expansion of these models to explain more complex behavior, such as empathy, still needs to be investigated in more detail. Finally, we broaden our outlook to social interaction, where virtual reality stimuli can be utilized to imitate complex social situations. PMID:26029133

    The goal of this proposal is to bring the theoretical interpretation of Young Stellar Object jets and their environments to a new level of realism. We propose to build on the results of a successful Cycle 16 observing proposal that has obtained 3rd epoch images of HH jets. We will use Adaptive Mesh Refinement MHD simulations {developed by our team} to carry forward a detailed program of modeling and interpretation of the time-dependent behavior revealed in the new, extended multi-epoch data set. Only with the third epoch observations can we explore forces: i.e. accelerations, decelerations and structural changes to develop an accurate understanding of physical processes occurring in hypersonic, magnetized jet flows. Our studies will allow us to characterize the jets and, therefore, make the crucial link with jet central engines. We note an innovative feature of our project is its link with laboratory astrophysical experiments of jets. Our analysis of the observations will be used to determine future laboratory experiments which will explore A?clumpyA? jet propagation issues.

    The reformulation of existing boundaries between primary and secondary care, in order to shift selected services traditionally provided by Emergency Departments (EDs) to community-based alternatives, has determined a variety of organisational solutions. One innovative change has been the introduction of fast-track systems for minor injuries or illnesses, whereby community care providers are involved in order to divert patients away from EDs. These facilities offer an open-access service for patients not requiring hospital treatments, and may be staffed by nurses and/or primary care general practitioners operating within, or alongside, the ED. To date little research has been undertaken on such experiences. To fill this gap, we analyse a Walk-in Centre (WiC) in the Italian city of Parma, consisting of a minor injury unit located alongside the teaching hospital's ED. We examine the link between the utilisation rates of the WiC and primary care characteristics, focusing on the main organisational features of the practices and estimating panel count data models for 2007-2010. Our main findings indicate that the extension of practice opening hours significantly lowers the number of attendances, after controlling for General Practitioner's and practice's characteristics.

    Bandiera, Lucia; Furini, Simone; Giordano, Emanuele

    2016-01-01

    The stochasticity due to the infrequent collisions among low copy-number molecules within the crowded cellular compartment is a feature of living systems. Single cell variability in gene expression within an isogenic population (i.e., biological noise) is usually described as the sum of two independent components: intrinsic and extrinsic stochasticity. Intrinsic stochasticity arises from the random occurrence of events inherent to the gene expression process (e.g., the burst-like synthesis of mRNA and protein molecules). Extrinsic fluctuations reflect the state of the biological system and its interaction with the intra and extracellular environments (e.g., concentration of available polymerases, ribosomes, metabolites, and micro-environmental conditions). A better understanding of cellular noise would help synthetic biologists design gene circuits with well-defined functional properties. In silico modeling has already revealed several aspects of the network topology’s impact on noise properties; this information could drive the selection of biological parts and the design of reliably engineered pathways. Importantly, while optimizing artificial gene circuitry for industrial applications, synthetic biology could also elucidate the natural mechanisms underlying natural phenotypic variability. In this review, we briefly summarize the functional roles of noise in unicellular organisms and address their relevance to synthetic network design. We will also consider how noise might influence the selection of network topologies supporting reliable functions, and how the variability of cellular events might be exploited when designing innovative biotechnology applications.

    Persons affected by leprosy or by disabilities face forms of stigma that have an impact on their lives. This study seeks to establish whether their experiences of stigma are similar, with a view to enabling the two groups of people to learn from each other. Accounts of experiences of the impact of stigma were obtained using in-depth interviews and focus group discussion with people affected by leprosy and by disabilities not related to leprosy. The analysis shows that there are a lot of similarities in impact of stigma in terms of emotions, thoughts, behaviour, and relationships between the two groups. The main difference is that those affected by leprosy tended to frame their situation in medical terms, while those living with disabilities described their situation from a more social perspective. In conclusion, the similarities offer opportunities for interventions and the positive attitudes and behaviours can be modelled in the sense that both groups can learn and benefit. Research that tackles different aspects of stigmatization faced by both groups could lead to inclusive initiatives that help individuals to come to terms with the stigma and to advocate against exclusion and discrimination.

    Periods of soil water deficit often occur within a plant's life cycle, even in temperate deciduous and rain forests (Wilson et al. 2001, Grace 1999). Various experiments have shown that roots are able to sense the distribution of water in the soil, and produce signals that trigger changes in leaf expansion rate and stomatal conductance (Blackman and Davies 1985, Gollan et al. 1986, Gowing et al. 1990 Davies and Zhang 1991, Mansfield and De Silva 1994, Sadras and Milroy 1996). Partitioning of water and air in the soil, solute distribution in soil water, water flow through the soil, and water availability for plants can be determined according to the distribution of the soil water potential (e.g. Schröder et al. 2013, Kool et al. 2014). Understanding plant water uptake under dry conditions has been compromised by hydrological instrumentation with low accuracy in dry soils due to signal attenuation, or a compromised measurement range (Whalley et al. 2013). Development of polymer tensiometers makes it possible to study the soil water potential over a range meaningful for studying plant responses to water stress (Bakker et al. 2007, Van der Ploeg et al. 2008, 2010). Polymer tensiometer data obtained from a lysimeter experiment (Van der Ploeg et al. 2008) were used to analyse day-night fluctuations of soil moisture in the vicinity of maize roots. To do so, three polymer tensiometers placed in the middle of the lysimeter from a control, dry and very dry treatment (one lysimeter per treatment) were used to calculate water content changes over 12 hours. These 12 hours corresponded with the operation of the growing light. Soil water potential measurements in the hour before the growing light was turned on or off were averaged. The averaged value was used as input for the van Genuchten (1980) model. Parameters for the model were obtained from laboratory determination of water retention, with a separate model parameterization for each lysimeter setup. Results show daily

    2014-01-01

    Most wearable activity recognition systems assume a predefined sensor deployment that remains unchanged during runtime. However, this assumption does not reflect real-life conditions. During the normal use of such systems, users may place the sensors in a position different from the predefined sensor placement. Also, sensors may move from their original location to a different one, due to a loose attachment. Activity recognition systems trained on activity patterns characteristic of a given sensor deployment may likely fail due to sensor displacements. In this work, we innovatively explore the effects of sensor displacement induced by both the intentional misplacement of sensors and self-placement by the user. The effects of sensor displacement are analyzed for standard activity recognition techniques, as well as for an alternate robust sensor fusion method proposed in a previous work. While classical recognition models show little tolerance to sensor displacement, the proposed method is proven to have notable capabilities to assimilate the changes introduced in the sensor position due to self-placement and provides considerable improvements for large misplacements.

    1998-07-01

    Academic medicine faces unprecedented challenges, especially the impact of the changing and more business-oriented health care system on medical education. There is an inherent clash of values between business and medicine: among key business values are profit and competition, while among the traditional values of the medical profession are service, advocacy, and altruism. Business interests have already gained a central place in medicine, so the challenge has become how to utilize the positive elements of the entrepreneurial spirit to enhance professional values and advance academic medicine's central enterprise. The author maintains that to achieve that synthesis, the leaders of academic medicine must continue to engage in a dialogue with the broader academic community, the government, the public, and the health care industry. The dialogue must emphasize (1) managing change rather than resisting it (such as focusing on the positive aspects of change, keeping sight of the fundamental professional values of medicine and medical education, and maintaining cool, rational judgment in the face of challenges); (2) making academic medicine's case with many constituencies, such as the health care industry, government, and the public; and (3) fostering professionalism by increasing medical schools' emphasis on this task, by ensuring that schools keep an appropriate balance between the science and the art of medicine, and by having faculty model appropriate professional values for their students. The author concludes that while change inevitably brings challenge and a sense of loss, it also brings the opportunity to help reshape medical education to meet the needs of society. PMID:9679463

  1. Dealing with death: first encounters for first-year nursing students.

    Terry, Louise M; Carroll, Jo

    End-of-life care, particularly for older people, is often sub-optimal in England, and the Government has introduced several initiatives to improve this care. The authors believe the twin frameworks of emotional labour and ethics of non-abandonment underpin the provision of high-quality care. This article discusses a research project that investigated first-year nursing students' encounters with patient deaths. The research found that, to the student, every death in clinical practice is a learning experience and potentially a source of emotional distress; some students reported experiencing flashbacks afterwards and were developing avoidance behaviours. Students sometimes felt unsupported by mentors and also felt that sometimes dying patients and families were inadequately cared for. The theme of abandonment was evident in the students' stories. The authors conclude that there is still room for improvement in end-of-life care. Good role modelling and pastoral care by mentors is vital to student development. Link lecturers and mentors need to be alert to student distress. PMID:18825851

Activity recognition systems trained on activity patterns characteristic of a given sensor deployment may likely fail due to sensor displacements. In this work, we innovatively explore the effects of sensor displacement induced by both the intentional misplacement of sensors and self-placement by the user. The effects of sensor displacement are analyzed for standard activity recognition techniques, as well as for an alternate robust sensor fusion method proposed in a previous work. While classical recognition models show little tolerance to sensor displacement, the proposed method is proven to have notable capabilities to assimilate the changes introduced in the sensor position due to self-placement and provides considerable improvements for large misplacements.

    The exponential increase of knowledge in the life sciences field, more specifically in health sciences, in the past few years has brought additional levels of complexity when deciding and implementing strategies in the health care system. A predominantly paternalistic way to decide about available options to maintain or improve individual or collective health has been moving to a shared-decision model considering the empowered patient. In spite of the reduction of uncertainty when making health and health care decisions due to the advancement in scientific methods, and, in spite of the asymmetry of information, knowledge and power to make decisions, we are progressively recognizing the importance of individuals, the target of the intervention, to express their preferences and to take an active role in the decision making process. Health care stakeholders, recognizing the scarcity of resources available and the fortunate ever increasing amount of applicable knowledge and its corresponding interventions to improve the population quantity and quality of life, should stimulate society to address and discuss health care issues that will guide critical choices and define health care priorities based mostly on judgment and the best evidence available.

    Functional near-infrared spectroscopy (fNIRS) may be suited for functional monitoring during swallowing as it is comparatively immune to body movement. However, still fNIRS measurement on swallowing poses a technical problem that it may often involve motion artifacts. Although there is no single way to solve this problem, technical insights have been available form related studies in the past. Here we introduce two examples for analyzing data rich in motion artifacts putting emphasis on temporal structures of the data. The first is about fNIRS assessment of language function during overt naming tasks. Since data were temporally continuous, we adopted a general linear model with regression to a canonical hemodynamic response function to extract cortical activations related to overt naming tasks. The second example is about fNIRS assessment on go/no-go task performance with or without methylphenidate administration in Attention Deficit Hyperactivity Disorder (ADHD) children. Since data were disrupted by unexpected motion artifacts, we simplified temporal data structures by averaging to extract only robust signals. Thus, we indicated that the optimum analytical strategy varies depending on the temporal structures of the data. PMID:23196558

  6. Dealing with completeness, structural hierarchy, and seismic coupling issues: three major challenges for #Fault2SHA

    The vast majority of active faulting studies are performed at the scale of individual, presumably seismogenic faults or fault strands. Most SHA approaches and models, however, require homogeneus information on potential earthquake sources over the entire tectonic domain encompassing the site(s) of interest. Although it is out of question that accurate SHA must rely on robust investigations of individual potential earthquake sources, it is only by gathering this information in regionally extensive databases that one can address some of the most outstanding issues in the use of #Fault2SHA. We will briefly recall three issues that are particularly relevant in the investigation of seismogenic faulting in southern Europe. A fundamental challenge is the completeness of the geologic record of active faulting. In most tectonic environments many potential seismogenic faults are blind or hidden, or deform the lower crust without leaving a discernible signal at the surface, or occur offshore, or slip so slowly that nontectonic erosional-depositional processes easily outpace their surface effects. Investigating only well-expressed faults is scientifically rewarding but also potentially misleading as it draws attention on the least insidious faults, leading to a potential underestimation of the regional earthquake potential. A further issue concerns the hierarchy of fault systems. Most active faults do not comprise seismogenic sources per se but are part of larger systems, and slip only in conjunction with the master fault of each system. In the most insidious cases, only secondary faults are expressed at the surface while the master fault lies hidden beneath them. This may result in an overestimation of the true number of seismogenic sources that occur in each region and in a biased identification of the characteristics of the main player in each system. Recent investigations of geologic and geodetic vs earthquake release budgets have shown that the "seismic coupling", which

    2016-01-01

    Background: Pediatric dental fear, if left unchecked, can persist for a lifetime and adversely impact the physical and psychological health of a patient. In this study, a feasible nonmedical method for relieving pediatric dental fear was investigated. Methods: A randomized, single-blind, controlled trial model was applied. The juvenile patients experiencing dental fear, whose parents or guardian had signed an informed consent form, were randomly divided into two groups. Group A (n = 50) was the control group, while Group B (n = 50) was the reward group. Participants in Group A accepted routine treatment. Participants in Group B were told that they would obtain a gift as a reward for their good behavior if they were compliant during their dental treatments. The Chinese version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) was used to evaluate the level of dental fear of each patient both before and after each treatment. A contrast analysis and a correlation analysis of the results were used to assess the efficacy of the reward mechanism. Results: All participants in Group B, were obedient during the dental treatment, and they also successfully chose the present they wanted at the end of their dental treatment. Children at different ages showed different reward preferences. Significant difference in the fear scores of the participants in Group B before the treatment and after receiving the reward was found (independent samples t-test, t = 14.72, P < 0.001). In Group A, 86% children's fear score did not undergo a noticeable change. Conclusions: A reward system is proved feasible to relieve pediatric dental fear, and the form of reward should meet the demand of patients. PMID:27503018

  8. Dealing with the clandestine nature of wildlife-trade market surveys.

    PubMed

    Barber-Meyer, Shannon M

    2010-08-01

    Illegal international trade in wildlife (excluding fisheries and timber) has been valued at more than US$20 billion. A more precise figure has not been determined in part because of the clandestine nature of the trade, and for this same reason even regional and local levels of wildlife trade are difficult to assess. The application of recent developments in wildlife field-survey methods (e.g., occupancy) now allows for a more-accurate estimation of wildlife trade occurrence, including its hidden components at a variety of scales (e.g., regional, local) and periods (e.g., single season, 1 year, multiple years). Occupancy models have been applied in wildlife field studies to address the problem of false absences when conducting presence-absence surveys. Occupancy surveys differ from traditional presence-absence surveys because they incorporate repeat surveys, allowing for the likelihood of detecting a species (the probability of detection) to be estimated explicitly (in contrast to traditional surveys that often incorrectly treat this probability as close to one to allow for estimation of presence). Occupancy methods can be applied to a variety of wildlife-trade surveys, including, for example, single-species availability, links between two illegally traded species (i.e., co-occurrence), and disease occurrence in live trade. In addition, free user-friendly software (i.e., PRESENCE) allows even nonstatisticians to adequately address this issue. I simulated a hypothetical wildlife-trade market survey that resulted in an apparent 20% decline in naïve occupancy (proportion of surveyed towns engaged in the trade) over 2 years, but when I accounted for change in probability of detection over the years the difference in occupancy was not statistically significant. As more sophisticated methods, such as occupancy, are applied to wildlife-trade market surveys, results will be more robust and defensible and therefore, theoretically, more powerful when presented to

    1989-01-01

    Political persecution, state terrorism, torture, political assassinations, kidnapping and forced exile have become common occurrences in many parts of the world. Several researchers have tried to determine the impact of these situations on the mental health of those affected. At the same time, different types of aid programmes have been developed to prevent and treat the effects of violence on mental health. In this article we present clinical materials collected for 10 years by the Latin American Collective of Psychosocial Work [Colectivo Latinamericano de Trabajo Psicosocial (Colat)], a medical-psychosocial assistance programme for political refugees. The programme was under the academic supervision of the Catholic Universities of Leuven (KUL, ULC), Belgium. The concept of identity is the central theme of a model which tries to understand and explain the suffering of exiles. We try to identify and expose the mechanisms of political violence that have traumatized an individual's self-esteem and disordered his familial and social bonds. In the second part of this article, the central ideas which support the medical-psychosocial practice of the programme are presented. This programme seeks to heal the damage caused by repression and exile through the active participation of those affected. Only in a context of communal action is it possible to develop a therapy to promote an individual recovery. It is in this sense that the strategic goal of the programme is to permit elaboration of the suffering at an individual, familial and group level, and to facilitate group dynamics which can trigger the potential of the exiles to transform the conditions of violence that originated and maintain their pain.

    2006-01-01

    As an integrated observing strategy, the concept of sensorweb for Earth observations is appealing in many aspects. For instance, by increasing the spatial and temporal coverage of observations from space and other vantage points, one can eventually aid in increasing the accuracy of the atmospheric models which are precursor to hurricane track prediction, volcanic eruption forecast, and trajectory path of transcontinental transport of dust, harmful nuclear and chemical plumes. In reality, there is little analysis available in terms of benefits, costs and optimized set of sensors needed to make these necessary observations. This is a complex problem that must be carefully studied and balanced over many boundaries such as science, defense, early warning, security, and surveillance. Simplistically, the sensorweb concept from the technological point of view alone has a great appeal in the defense, early warning and security applications. In fact, it can be relatively less expensive in per unit cost as opposed to building and deploying it for the scientific use. However, overall observing approach should not be singled out and aligned somewhat orthogonally to serve a particular need. On the other hand, the sensorweb should be designed and deployed to serve multiple subject areas and customers simultaneously; and can behave as directed measuring systems for both science and operational entities. Sensorweb can be designed to act as expert systems, and/or also provide a dedicated integrated surveillance network. Today, there is no system in the world that is fully integrated in terms of reporting timely multiple hazards warnings, computing the loss of life and property damage estimates, and is also designed to cater to everyone s needs. It is not an easier problem to undertake and more so is not practically solvable. At this time due to some recent events in the world, the scientific community, social scientists, and operational agencies are more cognizant and getting

    The upper Klamath Basin has been the center of conflict over competing water uses and values in recent years, exacerbated by drought conditions. Currently, water needs for irrigation, fish, and riparian environments are being addressed and plans for sharing limited water resources are being negotiated. In a number of major river basins in the western US, extended records of streamflow from tree rings have been found useful for planning by placing recent droughts in a long term context and characterizing the long-term hydrologic variability over past centuries. The focus of this research is the first reconstruction of the upper Klamath River and its potential use for management. One challenge in the reconstruction of Klamath River streamflow is the availability of high quality streamflow data for reconstruction model calibration. In the Klamath basin, a long history of diversions for irrigation along with complex wetland hydrology has made the accurate estimation of natural flows difficult. A number of sources of hydrology are available, but all show differences in magnitudes of high and low flows. While the uncertainties in the calibration streamflow data can be described and quantified, they cannot be overcome, and thus impart uncertainty to the resulting reconstruction. Thus, it is important to develop analysis strategies that highlight the most certain aspects of the reconstruction. In the case of the Klamath River records, the most robust information concerns the sequences of flow, and duration and frequency of wet and dry intervals. In the reconstruction, which extends from 1493-2010, analyses of frequency and distribution of extreme low flow years, runs of consecutive years of low flows, and the probability of transitions between wet and dry years all document long-term natural hydrologic variability, over which the impacts of climate change will be imposed. While not a perfect record of past flow, the Klamath reconstruction provides information that can be

Direct access to BRCA mutation tests, considered a model for high-risk actionable genetic tests of proven clinical utility, provided clear benefits to participants. The unexpected information demonstrated a cascade effect as relatives of newly identified carriers also sought testing and more mutation carriers were identified. Given the absence of evidence for serious emotional distress or inappropriate actions in this subset of mutation-positive customers who agreed to be interviewed for this study, broader screening of Ashkenazi Jewish women for these three BRCA mutations should be considered.

    Although rates of methamphetamine use continue to increase throughout the United States, little is known about the individuals who sell methamphetamine at the street level. This exploratory study examined the prevalence and correlates of drug-dealing behavior in a sample of 404 heterosexually-identified methamphetamine users who were participants in a sexual risk reduction intervention in San Diego, CA. Twenty-nine percent of participants (N = 116) reported “dealing” methamphetamine in the past two months. In a multivariate logistic regression, methamphetamine dealing was associated with being male (OR = 1.99; 95% CI 1.16 – 3.39), younger age (OR = 1.87 per year; 95% CI 1.10 – 3.17), more frequent use of methamphetamine (OR = 2.69; 95% CI 1.59 – 4.57), injecting methamphetamine (OR = 3.10; 95% CI 1.79 – 5.37), and higher hostility scores (OR = 1.07 per unit increase; 95% CI 1.01 – 1.13). These characteristics, particularly intensity of drug use and hostility, may be associated with greater resistance to drug treatment and lower success in treatment programs. PMID:21999496

    The aim of the study was twofold. The first aim was to develop on-line video clip material that showed examples of nurses dealing with potentially difficult and delicate patient groups. The second aim was to evaluate the effectiveness of video clip materials for enhancing nursing student's self-efficacy to effectively communicate with the type of patients described above. The production of contextually relevant video clip material involved the identification of relevant material based on real experiences, writing appropriate scripts, recruiting actors, recording the performances and producing them in a form that could be accessed on-line. Self-report questionnaires were used to assess the effectiveness of video clip material. Level 1 (n = 145) nursing students completed a self-efficacy measure that assessed confidence to deal with situations such as breaking news of death, working with children, people with disability and aggressive behaviour at the start and the end of the module. Results indicated that student's self-efficacy increased noticeably over the course of the module. Differences between increases in self-efficacy attributed to watching videos or attending lectures were marginal. Findings suggest that using video clips that show students effectively coping with adverse situations provide an effective teaching approach for enhancing self-efficacy. Future research is needed to test the extent to which self-efficacy measures relate with nursing performance. PMID:16300862

    On the 4th of July 1997, I lay on a blanket with my family at a fireworks display near our home in Los Angeles, California. The pyrotechnics, they tell me, were dazzling. I wouldn't know. My attention was fixed on a tiny orange dot in the sky - Mars. A month earlier, NASA had released an Announcement of Opportunity for a supplementary payload on the Mars Surveyor Lander mission scheduled for launch in 2001. The Human Exploration and Development of Space (HEDS) organization had been authorized to make the most preliminary of investigations into the feasibility of sending humans to Mars. Among the requested investigations was an opportunity to study the dust and soil of the Red Planet, emphasizing possible hazards to human explorers. I spent that summer of '97 working on a proposal for the project I would eventually lead, the Mars Environmental Compatibility Assessment (MECA). MECA was selected in February of '98. We promised to deliver four new instruments by April 2000 with a modest budget of $5M. This is a story about some of the people who created MECA.

    The repeated losses experienced by a clinical oncologist may constitute a significant source of personal stress. Studies documenting high stress levels on oncology services and the prevalence among physicians of alcoholism, cirrhosis, suicide, and marital discord lend urgency to the need to examine etiologic factors, clinical manifestations, and strategies for the management of job-related stress. Significant etiologic factors include death as an existential fact emphasizing our finite nature, the cumulative grief associated with repeated unresolved losses, the pressure of a health care system fueled by the medical information explosion, the inability to achieve the idealistic goals embraced by holistic medical care, stresses inherent in working as a "team," and an undermined context of meaning as an outcome of treatment failures. Clinical manifestations of stress are reviewed as an aid to early diagnosis. Strategies useful in the prevention and management of stress include the encouragement of increased awareness of stress in self and colleagues, the clarification of appropriate goals and priorities, encouragement of appropriate limit setting, the mobilization of collaborative input, the clarification of team roles and organizational patterns, the establishment of team support meetings and favorable working conditions, exercise, and the clarification and working through of previously unresolved personal psychodynamic issues.

    Teaching English to Engineering or Business students has always been a challenge. One of the major reasons which makes this task particularly challenging is the fact that, being graduates of various high schools, they join the university having very different levels of English. Some may have started English in kindergarten, while others only in high school. Some speak it fluently; others may barely be able to introduce themselves despite having studied it for a similar number of years as the former. This paper takes a look at the major challenges teachers of English in university are faced with when teaching multilevel classes, and attempts to offer some suggestions as to how to deal with this situation while at the same time keeping the quality of the teaching-learning process.

    Based on research on stereotype threat and multiple identities, this work explores the beneficial effects of activating a positive social identity when a negative identity is salient on women's performance in sports. Further, in line with research on the effects of anxiety in sports, we investigate whether the activation of a positive social identity buffers performance from cognitive anxiety associated with a negative stereotype. Two experiments tested these predictions in field settings. Experiment 1 (N = 83) shows that the simultaneous activation of a positive (i.e., member of a soccer team) and a negative social identity (i.e., woman) led to better performance than the activation of only a negative social identity for female soccer players. Experiment 2 (N = 46) demonstrates that identity condition moderated the effect of cognitive anxiety on performance for female basketball players. Results are discussed concerning multiple identities' potential for dealing with stressful situations. PMID:26442769

    Most advanced immersive devices provide collaborative environment within several users have their distinct head-tracked stereoscopic point of view. Combining with common used interactive features such as voice and gesture recognition, 3D mouse, haptic feedback, and spatialized audio rendering, these environments should faithfully reproduce a real context. However, even if many studies have been carried out on multimodal systems, we are far to definitively solve the issue of multimodal fusion, which consists in merging multimodal events coming from users and devices, into interpretable commands performed by the application. Multimodality and collaboration was often studied separately, despite of the fact that these two aspects share interesting similarities. We discuss how we address this problem, thought the design and implementation of a supervisor that is able to deal with both multimodal fusion and collaborative aspects. The aim of this supervisor is to ensure the merge of user's input from virtual reality devices in order to control immersive multi-user applications. We deal with this problem according to a practical point of view, because the main requirements of this supervisor was defined according to a industrial task proposed by our automotive partner, that as to be performed with multimodal and collaborative interactions in a co-located multi-user environment. In this task, two co-located workers of a virtual assembly chain has to cooperate to insert a seat into the bodywork of a car, using haptic devices to feel collision and to manipulate objects, combining speech recognition and two hands gesture recognition as multimodal instructions. Besides the architectural aspect of this supervisor, we described how we ensure the modularity of our solution that could apply on different virtual reality platforms, interactive contexts and virtual contents. A virtual context observer included in this supervisor in was especially designed to be independent to the

    Dealing with socio-scientific issues in science classes enables students to participate productively in controversial discussions concerning ethical topics, such as sustainable development. In this respect, well-structured decision-making processes are essential for elaborate reasoning. To foster decision-making competence, a computer-based programme was developed that trains secondary school students (grades 11-13) in decision-making strategies. The main research question is: does training students to use these strategies foster decision-making competence? In addition, the influence of meta-decision aids was examined. Students conducted a task analysis to select an appropriate strategy prior to the decision-making process. Hence, the second research question is: does combining decision-making training with a task analysis enhance decision-making competence at a higher rate? To answer these questions, 386 students were tested in a pre-post-follow-up control-group design that included two training groups (decision-making strategies/decision-making strategies combined with a task analysis) and a control group (decision-making with additional ecological information instead of strategic training). An open-ended questionnaire was used to assess decision-making competence in situations related to sustainable development. The decision-making training led to a significant improvement in the post-test and the follow-up, which was administered three months after the training. Long-term effects on the quality of the students' decisions were evident for both training groups. Gains in competence when reflecting upon the decision-making processes of others were found, to a lesser extent, in the training group that received the additional meta-decision training. In conclusion, training in decision-making strategies is a promising approach to deal with socio-scientific issues related to sustainable development.

    Models going beyond the rigid-rotor and the harmonic oscillator levels are mandatory for providing accurate theoretical predictions for several spectroscopic properties. Different strategies have been devised for this purpose. Among them, the treatment by perturbation theory of the molecular Hamiltonian after its expansion in power series of products of vibrational and rotational operators, also referred to as vibrational perturbation theory (VPT), is particularly appealing for its computational efficiency to treat medium-to-large systems. Moreover, generalized (GVPT) strategies combining the use of perturbative and variational formalisms can be adopted to further improve the accuracy of the results, with the first approach used for weakly coupled terms, and the second one to handle tightly coupled ones. In this context, the GVPT formulation for asymmetric, symmetric, and linear tops is revisited and fully generalized to both minima and first-order saddle points of the molecular potential energy surface. The computational strategies and approximations that can be adopted in dealing with GVPT computations are pointed out, with a particular attention devoted to the treatment of symmetry and degeneracies. A number of tests and applications are discussed, to show the possibilities of the developments, as regards both the variety of treatable systems and eligible methods. © 2015 Wiley Periodicals, Inc.

    Mass spectrometry, and especially electrospray ionization, is now an efficient tool to study noncovalent interactions between proteins and inhibitors. It is used here to study the interaction of some weak inhibitors with the NCoA-1/STAT6 protein with K(D) values in the microM range. High signal intensities corresponding to some nonspecific electrostatic interactions between NCoA-1 and the oppositely charged inhibitors were observed by nanoelectrospray mass spectrometry, due to the use of high ligand concentrations. Diverse strategies have already been developed to deal with nonspecific interactions, such as controlled dissociation in the gas phase, mathematical modeling, or the use of a reference protein to monitor the appearance of nonspecific complexes. We demonstrate here that this last methodology, validated only in the case of neutral sugar-protein interactions, i.e., where dipole-dipole interactions are crucial, is not relevant in the case of strong electrostatic interactions. Thus, we developed a novel strategy based on half-maximal inhibitory concentration (IC(50)) measurements in a competitive assay with readout by nanoelectrospray mass spectrometry. IC(50) values determined by MS were finally converted into dissociation constants that showed very good agreement with values determined in the liquid phase using a fluorescence polarization assay.

    Recording Cultural Heritage objects using terrestrial laserscanning becomes more and more popular over the last years. Since terrestrial Laserscanning System (TLS) Manufacturers have strongly increased the amount and speed of data captured with a single scan at each system upgrade and cutting down system costs the use of TLS Systems for recording cultural heritage is an option for recording worth to think about beside traditional methods like Photogrammetric. TLS Systems can be a great tool for capturing complex cultural heritage object within a short amount of time beside the traditional methods but can be a nightmare to handle for further process if not used right while capturing. Furthermore TLS Systems still have to be recognized as survey equipment, even though some of the manufactures promote them as everyday tool. They have to be used in an intelligent way having in mind the clients and the individual cultural objects needs. Thus the efficient way to use TLS Systems for data recording becomes a relevant topic to deal with the huge Amount of data the Systems collect while recording. Already small projects can turn into huge Pointcloud Datasets that End user, like Architects or Archaeologist neither can't deal with as their technical equipment doesn't fit the requirements of the Dataset nor do they have the software tools to use the Data as the current software tools still are high prized. Even the necessary interpretation of the Dataset can be a tough task if the people who have to work on with the Pointcloud aren't educated right in order to understand TLS and the results it creates. The use of TLS Systems has to have in mind the project requirements of the individual Heritage Object, like the required accuracy, standards for Levels of Details (e.g. "Empfehlungen für die Baudokumentation, Günther Eckstein, Germany"), the required kind of Deliverables (Visualization, 2D Drawings, True Deformation Drawings, 3D Models, BIM or 4D - Animations) as well as the

    The study was a randomized controlled trial evaluating the efficacy of a brief and preventatively-focused parenting discussion group for dealing with disobedient behavior in preschool-aged children. Eighty-five parents with children aged between 3 and 5 years who were concerned about the noncompliant behavior of their child were recruited from Auckland, New Zealand and Brisbane, Australia. Compared to the waitlist control group (n = 40), parents in the intervention group (n = 45) reported greater improvements in disruptive child behavior, ineffective parenting practices and parenting confidence, as well as clinically significant improvements in child behavior and parenting. All of these effects were maintained at 6-month follow up. No group differences were found for parental wellbeing, inter-parental conflict and general relationship quality, although intervention parents reported improvements in parental wellbeing and inter-parental conflict at 6-month follow-up. The findings are discussed in terms of the implications for making brief and effective parenting support available to parents. PMID:25863790

    This study aimed to analyze the influence of victim-related and observer-related factors in victim blaming of battered women. Two hundred and forty six college students participated. They were asked to read a scenario describing a hypothetical case of physical violence perpetrated by a man against his partner. Depending on the experimental condition, the victim was described either as a feminist and/or as exhibiting difficulties in her relationship with others or not. A hierarchical regression analysis was performed with victim blaming as dependent variable. Participants' hostile sexism positively predicted victim blaming when the victim was described as a feminist and as a "difficult to deal with" woman (p < .001). In addition, men, but not women, high in hostile sexist attitudes placed more blame on the victim when she was presented as a feminist woman (p < .001). These results underscore the importance of victim-related and observer-related factors, and of their interaction, in blaming the victim of gender-based violence. PMID:25011491

    2016-04-01

    Based on theory regarding the dynamics of organizational double binds, hypotheses were developed about interactive effects of role conflict, role ambiguity, and coping on psychological exhaustion. Hypotheses were tested in a sample of 948 civil servants employed by a government administration in Germany. The sample included 250 (26.4%) women (M age = 43.6 year, SD = 8.3) and average organizational tenure was 17.1 year (SD = 10.0). Moderated multiple regression supported the two hypothesized three-way interactions. Under conditions of high role conflict and high role ambiguity, exhaustion was lower in workers reporting high control coping than in workers reporting low control coping. Under conditions of high role conflict and high role ambiguity, worker exhaustion was more pronounced when support coping was high than when it was low. Problem-focused control coping seems crucial to maintain mental health in dealing with contradictory and unclear work role expectations. Emotion-focused support coping appears symptomatic of prolonged involvement in psychologically dysfunctional work situations that cannot otherwise be addressed. Implications are discussed in the context of growing awareness of the contradictory demands organizations impose on employees. PMID:27154375

    Two main strategies allow plants to deal with submergence: (i) escape from below water by means of shoot elongation, or (ii) remaining quiescent under the water until water subsides and then resume growth. We investigated these strategies in seedlings of Lotus japonicus, L. corniculatus and L. tenuis subjected to control and submergence for 12 days, with a subsequent 30-day recovery period. All three species survived submergence but used different strategies. Submerged seedlings of L. japonicus exhibited an escape strategy (emerging from water) as a result of preferential carbon allocation towards shoot mass and lengthening, in detriment to root growth. In contrast, seedlings of L. corniculatus and L. tenuis became quiescent, with no biomass accumulation, no new unfolding of leaves and no shoot elongation. Upon de-submergence, seedlings of L. japonicus had the lowest recovery growth (a biomass and shoot height 58% and 40% less than controls, respectively), L. corniculatus was intermediate and L. tenuis showed the greatest recovery growth. Previously submerged seedlings of L. tenuis did not differ from their controls, either in final shoot biomass or shoot height. Thus, for the studied species, quiescence appears to be an adequate strategy for tolerance of short-term (i.e., 12 days) complete submergence, being consistent with field observations of L. tenuis colonisation of flood-prone environments.

    The extent to which various interventions to deal with the young driver crash problem have worked are discussed, and promising interventions that should be tried are identified. Traditional forms of driver licensing and driver education have not worked. Graduated licensing reduces the problem and existing laws need to be strengthened. Programs involving parents and police have shown some potential to increase compliance with graduated licensing restrictions. Insurer discount programs also have potential. In other public health areas, comprehensive programs have worked better than those based on single components. There are continuing efforts to develop new driver education and training programs and methods of delivery that can combine with graduated licensing and contribute to reductions in the young driver problem. The most promising intervention strategy is likely to be a coordinated community based program in states with strong graduated licensing laws as a foundation, involving modern education and training techniques, insurance discount programs, and well publicized enforcement and education programs featuring parents and police in combination, with as much input and participation as possible from the target group of young drivers.

    The attention of scientists in the field of environmental radioactivity is drawn to statistical methods recommended by Dennis Helsel for dealing with datasets including measurements that fall below the detection limits, as often encountered in environmental monitoring programmes. The methods are described by Helsel in his book entitled "Nondetects and Data Analysis: Statistics for Censored Environmental Data" (John Wiley and Sons, New York, 2005, 250p). These methods are applied to a data subset (using data from France) of the Radioactive Substance Committee (OSPAR commission for the protection of the marine environment of the North-East Atlantic), corresponding to time-series measurements of Cs-137 concentration in seaweed in the vicinity of the Areva NC reprocessing plant at La Hague, which is used as an illustrative example. Despite the presence of 163 non-detect values out of 514 measurements, it is possible to estimate descriptive parameters and perform statistical tests to compare concentration levels between two periods of time. Finally, evidence is obtained for an overall decreasing trend with time. The benefits of these statistical methods for data analysis are discussed. PMID:19781826

    2011-06-01

    How we frame our thoughts about chronic opioid therapy greatly influences our ability to practice patient-centered care. Even providers who strive to be nonjudgmental may approach clinical decision-making about opioids by considering if the pain is real or they can trust the patient. Not only does this framework potentially lead to poor or unshared decision-making, it likely adds to provider and patient discomfort by placing the provider in the position of a police officer or a judge. Similarly, providers often find themselves making deals with patients using a positional bargaining approach. Even if a compromise is reached, this framework can potentially inadvertently weaken the therapeutic relationship by encouraging the idea that the patient and provider have opposing goals. Reframing the issue can allow the provider to be in a more therapeutic role. As recommended in the American Pain Society/American Academy of Pain Medicine guidelines, providers should decide whether the benefits of opioid therapy are likely to outweigh the harms for a specific patient (or sometimes, for society) at a specific time. This article discusses how providers can use a benefit-to-harm framework to make and communicate decisions about the initiation, continuation, and discontinuation of opioids for managing chronic nonmalignant pain. Such an approach focuses decisions and discussions on judging the treatment, not the patient. It allows the provider and the patient to ally together and make shared decisions regarding a common goal. Moving to a risk-benefit framework may allow providers to provide more patient-centered care, while also increasing provider and patient comfort with adequately monitoring for harm. PMID:21539703

    To assess the level of awareness about the different provisions of the persons with Disability Act (1995) among the health care professionals, 201 health care professionals dealing with the disabled persons from different parts of India were interviewed using structured interview checklist. The data were analysed through statistical package of social sciences software. Chi-square test were applied on the variables and the Pvalues were ascertained. The results show that 48.3% knew about administration hierarchy, 53.7% of respondents were aware of the free education available for the disabled, 68.5% were aware of the employment scheme, 62.7% about poverty alleviation schemes, 59.2% know about the traveling benefits, 56.2% of professionals were aware of the benefits for people with low vision. Only 29.9% of respondents knew about provisions to overcome architectural barriers. 43.8% of them knew about the least disability percentage whereas only 28.4% were aware of research and manpower schemes. Regarding affirmative action, 32.17% told correctly and 52.7% of the professionals responded correctly with respectto non- discrimination schemes. The level of awareness among the professionals working in rural regions is lower with regard to administration hierarchy and poverty alleviation schemes. Informations regarding disabled friendly environments and research and manpower development were found to be low among respondents of all professions which need to be effectively intervened. Gender did not show any influence with respect to the components of the act. The study showed that there is an ample need for educational interventions among the health care professionals in all socio-demography. Inclusion of PWD Act in the curriculum of medical schools as a topic in conferences and workshops for health care professionals are suggested. PMID:20329362

    2006-05-01

    This article presents an overview of the SecurePhone project, with an account of the first results obtained. SecurePhone's primary aim is to realise a mobile phone prototype - the 'SecurePhone' - in which biometrical authentication enables users to deal secure, dependable transactions over a mobile network. The SecurePhone is based on a commercial PDA-phone, supplemented with specific software modules and a customised SIM card. It integrates in a single environment a number of advanced features: access to cryptographic keys through strong multimodal biometric authentication; appending and verification of digital signatures; real-time exchange and interactive modification of (esigned) documents and voice recordings. SecurePhone's 'biometric recogniser' is based on original research. A fused combination of three different biometric methods - speaker, face and handwritten signature verification - is exploited, with no need for dedicated hardware components. The adoption of non-intrusive, psychologically neutral biometric techniques is expected to mitigate rejection problems that often inhibit the social use of biometrics, and speed up the spread of e-signature technology. Successful biometric authentication grants access to SecurePhone's built-in esignature services through a user-friendly interface. Special emphasis is accorded to the definition of a trustworthy security chain model covering all aspects of system operation. The SecurePhone is expected to boost m-commerce and open new scenarios for m-business and m-work, by changing the way people interact and by improving trust and confidence in information technologies, often considered intimidating and difficult to use. Exploitation plans will also explore other application domains (physical and logical access control, securised mobile communications).

    The majority of studies on idiosyncratic employment arrangements ("i-deals") are based on social exchange theory. The authors suggest that self-enhancement theory, in addition to social exchange, can be used to explain the effects of i-deals. Using a multisource sample including 230 employees and 102 supervisors from 2 Chinese companies, the authors adopt a 3-wave lagged design to examine the mediating roles of social exchange and self-enhancement and the moderating role of individualism in the relationships between i-deals and employee outcomes, as indicated by proactive behaviors and affective commitment. The results of bootstrapping analyses confirm the mediating effects of social exchange and self-enhancement. In addition, employees with high levels of individualism are more receptive to self-enhancement effects; in contrast, employees with low levels of individualism are more receptive to social exchange effects.

    A gas-exchange structure interacts with the environment and is constantly challenged by contaminants that may elicit defense responses, thus compromising its primary function. It is also exposed to high concentrations of O(2) that can generate reactive oxygen species (ROS). Revisiting the lung of mammals, an integrative picture emerges, indicating that this bronchi-alveolar structure deals with inflammation in a special way, which minimizes compromising the gas-exchange role. Depending on the challenge, pro-inflammatory or antiinflammatory responses are elicited by conserved molecules, such as surfactant proteins A and D. An even broader picture points to the participation of airway sensors, responsive to inflammatory mediators, in a loop linking the immunological and nervous systems and expanding the role played by respiratory organs in functions other than gas-exchange. A byproduct of exposure to high concentration of O(2) is the formation of superoxide ( ), hydrogen peroxide (H(2)O(2)), hydroxyl radical (HO(•)), and other ROS, which are known to be toxic to different types of cells, including the lung epithelium. A balance between antioxidants and oxidants exists; in pulmonary epithelial cells high intracellular and extracellular levels of antioxidants are found. Antioxidant adaptations related to plant and animal life-styles involve a broad range of overlapping strategies based on well-conserved molecules. Glutathione (GSH) is an abundant and ubiquitous thiol-tripeptide antioxidant, also present in lungs, whose role in providing information on the intracellular redox state of animals and plants is well established. In these organisms, GSH influences gene expression associated with stress, maximizing defense responses. Several enzymatic antioxidants, such as glutathione peroxidase (GPx), glutathione reductase, glutathione S-transferase, and glucose 6-phosphate dehydrogenase participate in the redox system; in animals that are stress-tolerant GPx is a key

  10. Show what you know and deal with stress yourself: a qualitative interview study of medical interns’ perceptions of stress and gender

    2014-01-01

    Background Medical students report high stress levels and in particular, the clinical phase is a demanding one. The field of medicine is still described as having a patriarchal culture which favors aspects like a physicians’ perceived certainty and rationalism. Also, the Effort-Recovery Model explains stress as coming from a discrepancy between job demands, job control, and perceived work potential. Gendered differences in stress are reported, but not much is known about medical interns’ perceptions of how gender plays in relation to stress. The aim of this study is to explore how medical interns experience and cope with stress, as well as how they reflect on the gendered aspects of stress. Methods In order to do this, we have performed a qualitative study. In 2010–2011, semi-structured qualitative interviews were conducted with seventeen medical interns across all three years of the Masters programme (6 male, 11 female) at a Dutch medical school. The interview guide is based on gender theory, the Effort-Recovery Model, and empirical literature. Transcribed interviews have been analyzed thematically. Results First, stress mainly evolves from having to prove one’s self and show off competencies and motivation (“Show What You Know…”). Second, interns seek own solutions for handling stress because it is not open for discussion (… “And Deal With Stress Yourself”). Patient encounters are a source of pride and satisfaction rather than a source of stress. But interns report having to present themselves as ‘professional and self-confident’, remaining silent about experiencing stress. Female students are perceived to have more stress and to study harder in order to live up to expectations. Conclusions The implicit message interns hear is to remain silent about insecurities and stress, and, in particular, female students might face disadvantages. Students who feel less able to manifest the ‘masculine protest’ may benefit from a culture that

    Incomplete data are generally a challenge to the analysis of most large studies. The current gold standard to account for missing data is multiple imputation, and more specifically multiple imputation with chained equations (MICE). Numerous studies have been conducted to illustrate the performance of MICE for missing covariate data. The results show that the method works well in various situations. However, less is known about its performance in more complex models, specifically when the outcome is multivariate as in longitudinal studies. In current practice, the multivariate nature of the longitudinal outcome is often neglected in the imputation procedure, or only the baseline outcome is used to impute missing covariates. In this work, we evaluate the performance of MICE using different strategies to include a longitudinal outcome into the imputation models and compare it with a fully Bayesian approach that jointly imputes missing values and estimates the parameters of the longitudinal model. Results from simulation and a real data example show that MICE requires the analyst to correctly specify which components of the longitudinal process need to be included in the imputation models in order to obtain unbiased results. The full Bayesian approach, on the other hand, does not require the analyst to explicitly specify how the longitudinal outcome enters the imputation models. It performed well under different scenarios. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27042954

    At the international level climate services are recognized as innovative tools aimed at providing and distributing climate data and information according to the needs of end-users. Furthermore, needs-based climate services are extremely effective to manage climate risks and take advantage of the opportunities associated with climate change impacts. To date, climate services are mainly related to climate models that supply climate data (e.g. temperature, precipitations) at different spatial and time scales. However, there is a significant gap of tools aimed at providing information about risks and impacts induced by climate change and allowing non-expert stakeholders to use both climate-model and climate-impact data. DESYCO is a GIS-Decision Support System aimed at the integrated assessment of multiple climate change impacts on vulnerable coastal systems (e.g. beaches, river deltas, estuaries and lagoons, wetlands, agricultural and urban areas). It is an open source software that manages different input data (e.g. raster or shapefiles) coming from climate models (e.g. global and regional climate projections) and high resolution impact models (e.g. hydrodynamic, hydrological and biogeochemical simulations) in order to provide hazard, exposure, susceptibility, risk and damage maps for the identification and prioritization of hot-spot areas and to provide a basis for the definition of coastal adaptation and management strategies. Within the CLIM-RUN project (FP7) DESYCO is proposed as an helpful tool to bridge the gap between climate data and stakeholder needs and will be applied to the coastal area of the North Adriatic Sea (Italy) in order to provide climate services for local authorities involved in coastal zone management. Accordingly, a first workshop was held in Venice (Italy) with coastal authorities, climate experts and climate change risk experts, in order to start an iterative exchange of information about the knowledge related to climate change, climate

    Hand in hand with the increasing availability of high resolution digital elevation models (DEMs), an efficient computation of land-surface parameters (LSPs) for large-scale digital elevation models becomes more and more important, in particular for web-based applications. Parallel processing using multi-threads on multi-core processors is a standard approach to decrease computing time for the calculation of local LSPs based on moving window operations (e.g. slope, curvature). LSPs which require non-localities for their calculation (e.g. hydrological connectivities of grid cells) make parallelization quite challenging due to data dependencies. On the example of the calculation of the LSP "flow accumulation", we test the two parallelization strategies "spatial decomposition" and "two phase approach" for their suitability to manage non-localities. Three datasets of digital elevation models with high spatial resolutions are used in our evaluation. These models are representative types of landscape of Central Europe with highly diverse geomorphic characteristics: a high mountains area, a low mountain range, and a floodplain area in the lowlands. Both parallelization strategies are evaluated with regard to their usability on these diversely structured areas. Besides the correctness analysis of calculated relief parameters (i.e. catchment areas), priority is given to the analysis of speed-ups achieved through the deployed strategies. As presumed, local surface parameters allow an almost ideal speed-up. The situation is different for the calculation of non-local parameters which requires specific strategies depending on the type of landscape. Nevertheless, still a significant decrease of computation time has been achieved. While the speed-ups of the computation of the high mountain dataset are higher by running the "spatial decomposition approach" (3.2 by using four processors and 4.2 by using eight processors), the speed-ups of the "two phase approach" have proved to be

  9. A coupled stochastic inverse-management framework for dealing with nonpoint agriculture pollution under groundwater parameter uncertainty

    Llopis-Albert, Carlos; Palacios-Marqués, Daniel; Merigó, José M.

    2014-04-01

    In this paper a methodology for the stochastic management of groundwater quality problems is presented, which can be used to provide agricultural advisory services. A stochastic algorithm to solve the coupled flow and mass transport inverse problem is combined with a stochastic management approach to develop methods for integrating uncertainty; thus obtaining more reliable policies on groundwater nitrate pollution control from agriculture. The stochastic inverse model allows identifying non-Gaussian parameters and reducing uncertainty in heterogeneous aquifers by constraining stochastic simulations to data. The management model determines the spatial and temporal distribution of fertilizer application rates that maximizes net benefits in agriculture constrained by quality requirements in groundwater at various control sites. The quality constraints can be taken, for instance, by those given by water laws such as the EU Water Framework Directive (WFD). Furthermore, the methodology allows providing the trade-off between higher economic returns and reliability in meeting the environmental standards. Therefore, this new technology can help stakeholders in the decision-making process under an uncertainty environment. The methodology has been successfully applied to a 2D synthetic aquifer, where an uncertainty assessment has been carried out by means of Monte Carlo simulation techniques.

    The Barcelonnette area, part of the Ubaye-Valley in the South French Alps, is highly exposed to natural hazard (mudslides, debris flows, torrential floods, river floods, avalanches and rockfalls); La Valette, Poche, Super-Sauze, Faucon are examples of well-known risk settings studied by scientists for several decades. In the framework of the Mountain Risks network, young researchers are working on different steps and aspects of the protection of the communities. It requires the collaboration of experts from different disciplines assembling the "living with risk" chain that has to cover the identification of the hazard, the risk assessment, risk management and the socio-economic and political decision-making. On the example of the Barcelonnette region, this work demonstrates such a multi-disciplinary cooperation within the Mountain Risks project. Starting with a multi-hazard analysis on a medium-scale level (1:10.000-1:50.000) for an overview over the hotspots in the basin a link is established to the local level analyses going into more detail. To forecast potential landslides in black marls and to assess the risk it is important to know the mechanisms leading to failure and the mechanisms determining subsequent movement. With respect to the Super-Sauze and La Valette mudslides detailed monitoring of hydrological features (i.e. high resolution temperature observations, large and medium scale infiltration experiments), displacement monitoring for short and long term kinematics analysis (i.e. image correlation technique applied on terrestrial oblique optical image, aerial and terrestrial laser scanning survey, differential global positioning system), small-scale testing in the laboratory (i.e. standard geotechnical, flume and centrifuge tests) and numerical modelling are performed to understand the mechanisms that might trigger and control the landslide. Integration and interpretation of these multi-source data allow to constrain conceptual models which are essential

    Direct data of the Tiberias Basin (TB) deep-seated stratigraphy is limited. Therefore, imaging of suspected underlying salt deposits and their structure is carried out based on salt tectonics theory and shallow seismic data interpretation. It is supported by the geochemistry of surrounding springs and numerical modeling of fluid transport processes within the basin. The Tiberias Basin (TB) is a narrow pull-apart basin located along the Dead Sea Transform. It encompasses Lake Tiberias, which is the largest fresh water lake in the Levant. Saline onshore and offshore springs and seepages are known to contribute considerable amount of salt to the lake endangering its water quality. Since the early 1980's, deep-seated salt deposits are known to exist in the Tiberias basin subsurface as a result of one deep exploration borehole. Interpretation of onshore seismic data at the southern part of the basin reveals its structure and distribution. However, offshore seismic interpretation is debatable and leads to uncertainty regarding the structure and distribution of salt deposits under the lake. The results of the current study suggest that a salt diapir rises under the lake, piercing through the basin-fill adjacent to the western boundary fault of the basin. Chemical analyses show that some springs at the western shore of the Lake contain indications of dissolved halite. In addition, numerical modeling of brine flow suggests that shallow salt domes can allow brine plumes to reach the surface and discharge along the western coast. These results allow imaging and support the hypothesis regarding the occurrences of shallow salt structures in the vicinity of the lake and contribute valuable information for sustainable management of its water.

    Ground penetrating radars (GPR's) have been often applied to underground object imaging. However, conventional radar systems do not work sufficiently to detect anti-personnel plastic landmines. We propose a novel radar imaging system, which processes adaptively interferometric front-end data obtained at multiple-frequency points. The system deals with interferometric images using complex-valued self-organizing map (C-SOM). We demonstrate a successful visualization of a plastic mine buried near the ground surface.

    2015-09-01

    Solution (31)P NMR analysis following extraction with a mixture of sodium hydroxide and ethylenediaminetetraacetic acid is the most widely used method for detailed characterization of soil organic P. However, quantitative analysis of the (31)P NMR spectra is complicated by severe spectral overlap in the monoester region. Various deconvolution procedures have been developed for the task, yet none of these are widely accepted or implemented. In this mini-review, we first describe and compare these varying approaches. We then review approaches to similar issues of spectral overlap in biomedical science applications including NMR-based metabolic profiling and analyzing (31)P magnetic resonance spectra of ex vivo and in vivo intact tissues. The greater maturity and resourcing of this biomedical research means that a wider variety of approaches has been developed. Of particular relevance are approaches to dealing with overlap of broad and sharp signals. Although the existence of this problem is still debated in the context of soil analyses, not only is it well-recognized in biomedical applications, but multiple approaches have been developed to deal with it, including T2 editing and time-domain fitting. Perhaps the most transferable concept is the incorporation of 'prior knowledge' in the fitting of spectra. This is well established in biomedical applications but barely touched in soil analyses. We argue that shortcuts to dealing with overlap in the monoester region (31)P NMR soil spectra are likely to be found in the biomedical literature, although some degree of adaptation will be necessary.

  14. Computational algorithms dealing with the classical and statistical mechanics of celestial scale polymers in space elevator technology

    NASA Astrophysics Data System (ADS)

    Knudsen, Steven; Golubovic, Leonardo

    Prospects to build Space Elevator (SE) systems have become realistic with ultra-strong materials such as carbon nano-tubes and diamond nano-threads. At cosmic length-scales, space elevators can be modeled as polymer like floppy strings of tethered mass beads. A new venue in SE science has emerged with the introduction of the Rotating Space Elevator (RSE) concept supported by novel algorithms discussed in this presentation. An RSE is a loopy string reaching into outer space. Unlike the classical geostationary SE concepts of Tsiolkovsky, Artsutanov, and Pearson, our RSE exhibits an internal rotation. Thanks to this, objects sliding along the RSE loop spontaneously oscillate between two turning points, one of which is close to the Earth whereas the other one is in outer space. The RSE concept thus solves a major problem in SE technology which is how to supply energy to the climbers moving along space elevator strings. The investigation of the classical and statistical mechanics of a floppy string interacting with objects sliding along it required development of subtle computational algorithms described in this presentation

    Adaptation planning assessments often rely on single methods for climate projection downscaling and hydrologic analysis, do not reveal uncertainties from associated method choices, and thus likely produce overly confident decision-support information. Recent work by the authors has highlighted this issue by identifying strengths and weaknesses of widely applied methods for downscaling climate projections and assessing hydrologic impacts. This work has shown that many of the methodological choices made can alter the magnitude, and even the sign of the climate change signal. Such results motivate consideration of both sources of method uncertainty within an impacts assessment. Consequently, the authors have pursued development of improved downscaling techniques spanning a range of method classes (quasi-dynamical and circulation-based statistical methods) and developed approaches to better account for hydrologic analysis uncertainty (multi-model; regional parameter estimation under forcing uncertainty). This presentation summarizes progress in the development of these methods, as well as implications of pursuing these developments. First, having access to these methods creates an opportunity to better reveal impacts uncertainty through multi-method ensembles, expanding on present-practice ensembles which are often based only on emissions scenarios and GCM choices. Second, such expansion of uncertainty treatment combined with an ever-expanding wealth of global climate projection information creates a challenge of how to use such a large ensemble for local adaptation planning. To address this challenge, the authors are evaluating methods for ensemble selection (considering the principles of fidelity, diversity and sensitivity) that is compatible with present-practice approaches for abstracting change scenarios from any "ensemble of opportunity". Early examples from this development will also be presented.

    Implantable polymers, as used for biomedical applications, inherently have to be sterile. Nonetheless, most implants, particularly those comprised of biomaterials developed in recent years for tissue engineering, are heat sensitive. Therefore, use of hazardous (radio)chemicals--due to lack of alternative methods--is still state of the art for sterilization processes. The drawbacks of these techniques, both drastic and well known, lead to the demand for an alternative sterilization method, which is equally obvious and urgent. High-pressure fluid treatment is a low-temperature technique that is already in use for pasteurization of liquid food products. This paper explores inactivation of vegetative microorganisms, spores, and endotoxins adherent to solid surfaces using compressed CO(2). Pressures ranging from 50 to 100 bar and temperatures from 25 °C to 50 °C were explored to investigate liquid, gaseous or supercritical state. Analysis of variance (ANOVA) and statistical modeling were used to identify the optimum parameter settings for inactivation of pathogenic bacteria and fungi (Candida albicans, Staphylococcus aureus). The addition of small amounts of ozone ensures inactivation of persistent spores (Bacillus stearothermophilus, B. subtilis) up to 10(6) cfu/ml, while endotoxins remain in practically unchanged concentration on the polymer surface. We then discuss environmental issues of the process and inactivation mechanisms. The replacement of conventional chemicals with nonpersistent ones resolves organizational and safety-related issues and protects natural resources as well as handling staff. The pressurized-fluid-based method exhibits mild treatment parameters, thus protecting sensitive textures. Finally, an outlook on possible applications of this innovative technique is presented.

    Fluorescence Correlation Spectroscopy (FCS) may be used to assay the binding of drug-like ligands to signaling proteins and other bio-particles. For High Throughput Screening (HTS), a competitive format is typically used in which binding of an unlabeled compound results in displacement of a fluorescently labeled ligand. Unweighted curve-fitting of the normalized autocorrelation function (ACF) to a two-diffusion-component model can resolve the fractions of free and bound ligand if the diffusion rates differ sufficiently and if the experimentally estimated ACF has adequate precision. However, for HTS (and also for intracellular FCS studies) it is desirable to minimize the experimental data collection time. In this case, the precision of the ACF is limited and it becomes important to account for the statistical features of the ACF estimate when designing an assay. The errors at different points in the estimated ACF are correlated and hence least-squares fitting methods are not strictly statistically rigorous. We compare different methods for estimating and curve-fitting the ACF from the raw data of short duration FCS measurements. The methods are applied to data from experiments to assay binding of Alexa-488-labeled Bak peptide with Bcl-xL, which is an intracellular protein that acts to protect against programmed cell death. We present results from a detailed Monte Carlo simulation of the experiment, which is useful for validating short-duration assay capabilities. We also discuss the measurement of changes in steady state fluorescence anisotropy due to restricted rotational diffusion upon binding, which provides a complementary assay method.

    Background Persistent presentation of medically unexplained symptoms (MUS) is troublesome for general practitioners (GPs) and causes pressure on the doctor-patient relationship. As a consequence, GPs face the problem of establishing an ongoing, preferably effective relationship with these patients. This study aims at exploring GPs' perceptions about explaining MUS to patients and about how relationships with these patients evolve over time in daily practice. Methods A qualitative approach, interviewing a purposive sample of twenty-two Dutch GPs within five focus groups. Data were analyzed according to the principles of constant comparative analysis. Results GPs recognise the importance of an adequate explanation of the diagnosis of MUS but often feel incapable of being able to explain it clearly to their patients. GPs therefore indicate that they try to reassure patients in non-specific ways, for example by telling patients that there is no disease, by using metaphors and by normalizing the symptoms. When patients keep returning with MUS, GPs report the importance of maintaining the doctor-patient relationship. GPs describe three different models to do this; mutual alliance characterized by ritual care (e.g. regular physical examination, regular doctor visits) with approval of the patient and the doctor, ambivalent alliance characterized by ritual care without approval of the doctor and non-alliance characterized by cutting off all reasons for encounter in which symptoms are not of somatic origin. Conclusion GPs feel difficulties in explaining the symptoms. GPs report that, when patients keep presenting with MUS, they focus on maintaining the doctor-patient relationship by using ritual care. In this care they meticulously balance between maintaining a good doctor-patient relationship and the prevention of unintended consequences of unnecessary interventions. PMID:19775481

    Slurry flows occur in many circumstances, including chemical manufacturing processes, pipeline transfer of coal, sand, and minerals; mud flows; and disposal of dredged materials. In this section we discuss slurry flow applications related to radioactive waste management. The Hanford tank waste solids and interstitial liquids will be mixed to form a slurry so it can be pumped out for retrieval and treatment. The waste is very complex chemically and physically. The ARIEL code is used to model the chemical interactions and fluid dynamics of the waste.
