    plan). Key parameters to be automatically determined are event origin time (within 0.1 sec), location (within 1 km) and size (within 0.3 magnitude units) without any human intervention. The key parameter ground truth information from explosions greater than magnitude 2.5 will be transmitted to a recording and transmitting site. Because we have identified a limited bandwidth, inexpensive two-way satellite communication (ORBCOMM), we have devised the concept of an accompanying Ground-Truth Processing Center that would enable calibration and ground-truth accuracy to improve over the duration of a deployment.

    The Savannah River Technology Center (SRTC) selected 13 sites across the continental US and one site in the western Pacific to serve as the primary or core site for collection of ground truth data for validation of MTI science algorithms. Imagery and ground truth data from several of these sites are presented in this paper. These sites are the Comanche Peak, Pilgrim and Turkey Point power plants, Ivanpah playas, Crater Lake, Stennis Space Center and the Tropical Western Pacific ARM site on the island of Nauru. Ground truth data includes water temperatures (bulk and skin), radiometric data, meteorological data and plant operating data. The organizations that manage these sites assist SRTC with its ground truth data collections and also give the MTI project a variety of ground truth measurements that they make for their own purposes. Collectively, the ground truth data from the 14 core sites constitute a comprehensive database for science algorithm validation

    Ground-truth measurements of precipitation and related weather events are an essential component of any satellite system designed for monitoring rainfall from space. Such measurements are required for testing, evaluation, and operations; they provide detailed information on the actual weather events, which can then be compared with satellite observations intended to provide both quantitative and qualitative information about them. Also, very comprehensive ground-truth observations should lead to a better understanding of precipitation fields and their relationships to satellite data. This process serves two very important functions: (a) aiding in the development and interpretation of schemes of analyzing satellite data, and (b) providing a continuing method for verifying satellite measurements.

    In this paper, we investigate human visual perception and establish a body of ground truth data elicited from human visual studies. We aim to build on the formative work of Ren, Eakins and Briggs who produced an initial ground truth database. Human subjects were asked to draw and rank their perceptions of the parts of a series of figurative images. These rankings were then used to score the perceptions, identify the preferred human breakdowns and thus allow us to induce perceptual rules for h...

  7. Fast and Accurate Ground Truth Generation for Skew-Tolerance Evaluation of Page Segmentation Algorithms

    2006-01-01

    Full Text Available Many image segmentation algorithms are known, but often there is an inherent obstacle in the unbiased evaluation of segmentation quality: the absence or lack of a common objective representation for segmentation results. Such a representation, known as the ground truth, is a description of what one should obtain as the result of ideal segmentation, independently of the segmentation algorithm used. The creation of ground truth is a laborious process and therefore any degree of automation is always welcome. Document image analysis is one of the areas where ground truths are employed. In this paper, we describe an automated tool called GROTTO intended to generate ground truths for skewed document images, which can be used for the performance evaluation of page segmentation algorithms. Some of these algorithms are claimed to be insensitive to skew (tilt of text lines. However, this fact is usually supported only by a visual comparison of what one obtains and what one should obtain since ground truths are mostly available for upright images, that is, those without skew. As a result, the evaluation is both subjective; that is, prone to errors, and tedious. Our tool allows users to quickly and easily produce many sufficiently accurate ground truths that can be employed in practice and therefore it facilitates automatic performance evaluation. The main idea is to utilize the ground truths available for upright images and the concept of the representative square [9] in order to produce the ground truths for skewed images. The usefulness of our tool is demonstrated through a number of experiments with real-document images of complex layout.

  8. ON CONSTRUCTION OF A RELIABLE GROUND TRUTH FOR EVALUATION OF VISUAL SLAM ALGORITHMS

    2016-11-01

    Full Text Available In this work we are concerning the problem of localization accuracy evaluation of visual-based Simultaneous Localization and Mapping (SLAM techniques. Quantitative evaluation of the SLAM algorithm performance is usually done using the established metrics of Relative pose error and Absolute trajectory error which require a precise and reliable ground truth. Such a ground truth is usually hard to obtain, while it requires an expensive external localization system. In this work we are proposing to use the SLAM algorithm itself to construct a reliable ground-truth by offline frame-by-frame processing. The generated ground-truth is suitable for evaluation of different SLAM systems, as well as for tuning the parametrization of the on-line SLAM. The presented practical experimental results indicate the feasibility of the proposed approach.

  10. AMS Ground Truth Measurements: Calibration and Test Lines

    2013-01-01

    Airborne gamma spectrometry is one of the primary techniques used to define the extent of ground contamination after a radiological incident. Its usefulness was demonstrated extensively during the response to the Fukushima nuclear power plant (NPP) accident in March-May 2011. To map ground contamination a set of scintillation detectors is mounted on an airborne platform (airplane or helicopter) and flown over contaminated areas. The acquisition system collects spectral information together with the aircraft position and altitude every second. To provide useful information to decision makers, the count rate data expressed in counts per second (cps) needs to be converted to the terrestrial component of the exposure rate 1 m above ground, or surface activity of isotopes of concern. This is done using conversion coefficients derived from calibration flights. During a large scale radiological event, multiple flights may be necessary and may require use of assets from different agencies. However, as the production of a single, consistent map product depicting the ground contamination is the primary goal, it is critical to establish very early into the event a common calibration line. Such a line should be flown periodically in order to normalize data collected from different aerial acquisition systems and potentially flown at different flight altitudes and speeds. In order to verify and validate individual aerial systems, the calibration line needs to be characterized in terms of ground truth measurements. This is especially important if the contamination is due to short-lived radionuclides. The process of establishing such a line, as well as necessary ground truth measurements, is described in this document.

  13. Modified ground-truthing: an accurate and cost-effective food environment validation method for town and rural areas.

    Caspi, Caitlin Eicher; Friebur, Robin

    2016-03-17

    A major concern in food environment research is the lack of accuracy in commercial business listings of food stores, which are convenient and commonly used. Accuracy concerns may be particularly pronounced in rural areas. Ground-truthing or on-site verification has been deemed the necessary standard to validate business listings, but researchers perceive this process to be costly and time-consuming. This study calculated the accuracy and cost of ground-truthing three town/rural areas in Minnesota, USA (an area of 564 miles, or 908 km), and simulated a modified validation process to increase efficiency without comprising accuracy. For traditional ground-truthing, all streets in the study area were driven, while the route and geographic coordinates of food stores were recorded. The process required 1510 miles (2430 km) of driving and 114 staff hours. The ground-truthed list of stores was compared with commercial business listings, which had an average positive predictive value (PPV) of 0.57 and sensitivity of 0.62 across the three sites. Using observations from the field, a modified process was proposed in which only the streets located within central commercial clusters (the 1/8 mile or 200 m buffer around any cluster of 2 stores) would be validated. Modified ground-truthing would have yielded an estimated PPV of 1.00 and sensitivity of 0.95, and would have resulted in a reduction in approximately 88 % of the mileage costs. We conclude that ground-truthing is necessary in town/rural settings. The modified ground-truthing process, with excellent accuracy at a fraction of the costs, suggests a new standard and warrants further evaluation.

  14. Satellite markers: a simple method for ground truth car pose on stereo video

    2018-04-01

    Artificial prediction of future location of other cars in the context of advanced safety systems is a must. The remote estimation of car pose and particularly its heading angle is key to predict its future location. Stereo vision systems allow to get the 3D information of a scene. Ground truth in this specific context is associated with referential information about the depth, shape and orientation of the objects present in the traffic scene. Creating 3D ground truth is a measurement and data fusion task associated with the combination of different kinds of sensors. The novelty of this paper is the method to generate ground truth car pose only from video data. When the method is applied to stereo video, it also provides the extrinsic camera parameters for each camera at frame level which are key to quantify the performance of a stereo vision system when it is moving because the system is subjected to undesired vibrations and/or leaning. We developed a video post-processing technique which employs a common camera calibration tool for the 3D ground truth generation. In our case study, we focus in accurate car heading angle estimation of a moving car under realistic imagery. As outcomes, our satellite marker method provides accurate car pose at frame level, and the instantaneous spatial orientation for each camera at frame level.

    Sandia National Laboratories (SNL), Los Alamos National Laboratory (LANL), and the Savannah River Technology Center (SRTC) have developed a diverse group of algorithms for processing and analyzing the data that will be collected by the Multispectral Thermal Imager (MTI) after launch late in 1999. Each of these algorithms must be verified by comparison to independent surface and atmospheric measurements. SRTC has selected 13 sites in the continental U.S. for ground truth data collections. These sites include a high altitude cold water target (Crater Lake), cooling lakes and towers in the warm, humid southeastern US, Department of Energy (DOE) climate research sites, the NASA Stennis satellite Validation and Verification (V and V) target array, waste sites at the Savannah River Site, mining sites in the Four Corners area and dry lake beds in the southwestern US. SRTC has established mutually beneficial relationships with the organizations that manage these sites to make use of their operating and research data and to install additional instrumentation needed for MTI algorithm V and V.

    Studies of time-continuous human behavioral phenomena often rely on ratings from multiple annotators. Since the ground truth of the target construct is often latent, the standard practice is to use ad-hoc metrics (such as averaging annotator ratings). Despite being easy to compute, such metrics may not provide accurate representations of the underlying construct. In this paper, we present a novel method for modeling multiple time series annotations over a continuous variable that computes the ground truth by modeling annotator specific distortions. We condition the ground truth on a set of features extracted from the data and further assume that the annotators provide their ratings as modification of the ground truth, with each annotator having specific distortion tendencies. We train the model using an Expectation-Maximization based algorithm and evaluate it on a study involving natural interaction between a child and a psychologist, to predict confidence ratings of the children's smiles. We compare and analyze the model against two baselines where: (i) the ground truth in considered to be framewise mean of ratings from various annotators and, (ii) each annotator is assumed to bear a distinct time delay in annotation and their annotations are aligned before computing the framewise mean.

    Observation of sea ice thickness is one of key issues to understand regional effect of global warming. One of approaches to monitor sea ice in large area is microwave remote sensing data analysis. However, ground truth must be necessary to discuss the effectivity of this kind of approach. The conventional method to acquire ground truth of ice thickness is drilling ice layer and directly measuring the thickness by a ruler. However, this method is destructive, time-consuming and limited spatial resolution. Although there are several methods to acquire ice thickness in non-destructive way, ground penetrating radar (GPR) can be effective solution because it can discriminate snow-ice and ice-sea water interface. In this paper, we carried out GPR measurement in Lake Saroma for relatively large area (200 m by 300 m, approximately) aiming to obtain grand truth for remote sensing data. GPR survey was conducted at 5 locations in the area. The direct measurement was also conducted simultaneously in order to calibrate GPR data for thickness estimation and to validate the result. Although GPR Bscan image obtained from 600MHz contains the reflection which may come from a structure under snow, the origin of the reflection is not obvious. Therefore, further analysis and interpretation of the GPR image, such as numerical simulation, additional signal processing and use of 200 MHz antenna, are required to move on thickness estimation.

    2015-01-01

    Purpose: To develop a technique that assesses the accuracy of the breathing phase-specific volume image generation process by patient-specific breathing motion model using the original free-breathing computed tomographic (CT) scans as ground truths. Methods: Sixteen lung cancer patients underwent a previously published protocol in which 25 free-breathing fast helical CT scans were acquired with a simultaneous breathing surrogate. A patient-specific motion model was constructed based on the tissue displacements determined by a state-of-the-art deformable image registration. The first image was arbitrarily selected as the reference image. The motion model was used, along with the free-breathing phase information of the original 25 image datasets, to generate a set of deformation vector fields that mapped the reference image to the 24 nonreference images. The high-pitch helically acquired original scans served as ground truths because they captured the instantaneous tissue positions during free breathing. Image similarity between the simulated and the original scans was assessed using deformable registration that evaluated the pointwise discordance throughout the lungs. Results: Qualitative comparisons using image overlays showed excellent agreement between the simulated images and the original images. Even large 2-cm diaphragm displacements were very well modeled, as was sliding motion across the lung–chest wall boundary. The mean error across the patient cohort was 1.15 ± 0.37 mm, and the mean 95th percentile error was 2.47 ± 0.78 mm. Conclusion: The proposed ground truth–based technique provided voxel-by-voxel accuracy analysis that could identify organ-specific or tumor-specific motion modeling errors for treatment planning. Despite a large variety of breathing patterns and lung deformations during the free-breathing scanning session, the 5-dimensionl CT technique was able to accurately reproduce the original helical CT scans, suggesting its

    2006-10-01

    An important task in robot vision is that of determining the position, orientation and trajectory of a moving camera relative to an observed object or scene. Many such visual tracking algorithms have been proposed in the computer vision, artificial intelligence and robotics literature over the past 30 years. However, it is seldom possible to explicitly measure the accuracy of these algorithms, since the ground-truth camera positions and orientations at each frame in a video sequence are not available for comparison with the outputs of the proposed vision systems. A method is presented for generating real visual test data with complete underlying ground truth. The method enables the production of long video sequences, filmed along complicated six-degree-of-freedom trajectories, featuring a variety of objects and scenes, for which complete ground-truth data are known including the camera position and orientation at every image frame, intrinsic camera calibration data, a lens distortion model and models of the viewed objects. This work encounters a fundamental measurement problem—how to evaluate the accuracy of measured ground truth data, which is itself intended for validation of other estimated data. Several approaches for reasoning about these accuracies are described.

    During the Space Shuttle Endeavour mission in October 1994, a remote-sensing campaign was carried out with the objectives of both radiometric and polarimetric calibration and ground truth data acquisition of bare soils. This paper presents the results obtained in the experiment. Polarimetric cross-talk and channel imbalance values, as well as radiometric calibration parameters, have been found to be within the science requirements for SAR images. Regarding ground truth measurements, a wide spread in the height rms values and correlation lengths has been observed, which was motivated a critical revisiting of surface parameters descriptors

    Kratz, Baerbel; Ens, Svitlana; Mueller, Jan; Buzug, Thorsten M.

    2011-01-01

    Purpose: In computed tomography (CT), metal objects in the region of interest introduce data inconsistencies during acquisition. Reconstructing these data results in an image with star shaped artifacts induced by the metal inconsistencies. To enhance image quality, the influence of the metal objects can be reduced by different metal artifact reduction (MAR) strategies. For an adequate evaluation of new MAR approaches a ground truth reference data set is needed. In technical evaluations, where phantoms can be measured with and without metal inserts, ground truth data can easily be obtained by a second reference data acquisition. Obviously, this is not possible for clinical data. Here, an alternative evaluation method is presented without the need of an additionally acquired reference data set. Methods: The proposed metric is based on an inherent ground truth for metal artifacts as well as MAR methods comparison, where no reference information in terms of a second acquisition is needed. The method is based on the forward projection of a reconstructed image, which is compared to the actually measured projection data. Results: The new evaluation technique is performed on phantom and on clinical CT data with and without MAR. The metric results are then compared with methods using a reference data set as well as an expert-based classification. It is shown that the new approach is an adequate quantification technique for artifact strength in reconstructed metal or MAR CT images. Conclusions: The presented method works solely on the original projection data itself, which yields some advantages compared to distance measures in image domain using two data sets. Beside this, no parameters have to be manually chosen. The new metric is a useful evaluation alternative when no reference data are available.

    Extracting key frames (KF) from video is of great interest in many applications, such as video summary, video organization, video compression, and prints from video. KF extraction is not a new problem. However, current literature has been focused mainly on sports or news video. In the consumer video space, the biggest challenges for key frame selection from consumer videos are the unconstrained content and lack of any preimposed structure. In this study, we conduct ground truth collection of key frames from video clips taken by digital cameras (as opposed to camcorders) using both first- and third-party judges. The goals of this study are: (1) to create a reference database of video clips reasonably representative of the consumer video space; (2) to identify associated key frames by which automated algorithms can be compared and judged for effectiveness; and (3) to uncover the criteria used by both first- and thirdparty human judges so these criteria can influence algorithm design. The findings from these ground truths will be discussed.

    One of the core values in terminal care the respect of patient 'autonomy'. This essay begins with a discussion of medical ethics principles and the Natural Death Act in Taiwan and then summarizes two medical ethical dilemmas, truth telling and advance care planning (ACP), faced in the development of hospice and palliative care in Taiwan. The terminal truth telling process incorporates the four basic principles of Assessment and preparation, Communication with family, Truth-telling process, and Support and follow up (the so-called "ACTs"). Many experts suggest practicing ACP by abiding by the following five steps: (1) presenting and illustrating topics; (2) facilitating a structured discussion; (3) completing documents with advanced directives (ADs); (4) reviewing and updating ADs; and (5) applying ADs in clinical circumstances. Finally, the myths and challenges in truth telling and ADs include the influence of healthcare system procedures and priorities, inadequate communication skills, and the psychological barriers of medical staffs. Good communication skills are critical to truth telling and ACP. Significant discussion about ACP should help engender mutual trust between patients and the medical staffs who take the time to establish such relationships. Promoting patient autonomy by providing the opportunity of a good death is an important goal of truth telling and ACP in which patients have opportunities to choose their terminal treatment.

    The throughput of electrophysiological recording is growing rapidly, allowing thousands of simultaneous channels, and there is a growing variety of spike sorting algorithms designed to extract neural firing events from such data. This creates an urgent need for standardized, automatic evaluation of the quality of neural units output by such algorithms. We introduce a suite of validation metrics that assess the credibility of a given automatic spike sorting algorithm applied to a given dataset. By rerunning the spike sorter two or more times, the metrics measure stability under various perturbations consistent with variations in the data itself, making no assumptions about the internal workings of the algorithm, and minimal assumptions about the noise. We illustrate the new metrics on standard sorting algorithms applied to both in vivo and ex vivo recordings, including a time series with overlapping spikes. We compare the metrics to existing quality measures, and to ground-truth accuracy in simulated time series. We provide a software implementation. Metrics have until now relied on ground-truth, simulated data, internal algorithm variables (e.g. cluster separation), or refractory violations. By contrast, by standardizing the interface, our metrics assess the reliability of any automatic algorithm without reference to internal variables (e.g. feature space) or physiological criteria. Stability is a prerequisite for reproducibility of results. Such metrics could reduce the significant human labor currently spent on validation, and should form an essential part of large-scale automated spike sorting and systematic benchmarking of algorithms.

    Purpose: Voxel based morphometry (VBM) is increasingly being used to detect diffusion tensor (DT) image abnormalities in patients for different pathologies. An important requisite for these VBM studies is the use of a high-dimensional, non-rigid coregistration technique, which is able to align both the spatial and the orientational information. Recent studies furthermore indicate that high-dimensional DT information should be included during coregistration for an optimal alignment. In this context, a population based DTI atlas is created that preserves the orientational DT information robustly and contains a minimal bias towards any specific individual data set. Methods: A ground truth evaluation method is developed using a single subject DT image that is deformed with 20 deformation fields. Thereafter, an atlas is constructed based on these 20 resulting images. Thereby, the non-rigid coregistration algorithm is based on a viscous fluid model and on mutual information. The fractional anisotropy (FA) maps as well as the DT elements are used as DT image information during the coregistration algorithm, in order to minimize the orientational alignment inaccuracies. Results: The population based DT atlas is compared with the ground truth image using accuracy and precision measures of spatial and orientational dependent metrics. Results indicate that the population based atlas preserves the orientational information in a robust way. Conclusion: A subject independent population based DT atlas is constructed and evaluated with a ground truth method. This atlas contains all available orientational information and can be used in future VBM studies as a reference system.

    Field Ground Truthing Data Collector is one of the four key components of the NASA funded ICCaRS project, being developed in Southeast Michigan. The ICCaRS ground truthing toolkit entertains comprehensive functions: 1) Field functions, including determining locations through GPS, gathering and geo-referencing visual data, laying out ground control points for AEROKAT flights, measuring the flight distance and height, and entering observations of land cover (and use) and health conditions of ecosystems and environments in the vicinity of the flight field; 2) Server synchronization functions, such as, downloading study-area maps, aerial photos and satellite images, uploading and synchronizing field-collected data with the distributed databases, calling the geospatial web services on the server side to conduct spatial querying, image analysis and processing, and receiving the processed results in field for near-real-time validation; and 3) Social network communication functions for direct technical assistance and pedagogical support, e.g., having video-conference calls in field with the supporting educators, scientists, and technologists, participating in Webinars, or engaging discussions with other-learning portals. This customized software package is being built on Apple iPhone/iPad and Google Maps/Earth. The technical infrastructures, data models, coupling methods between distributed geospatial data processing and field data collector tools, remote communication interfaces, coding schema, and functional flow charts will be illustrated and explained at the presentation.

    Full Text Available Multitemporal imagery is by and large geometrically and radiometrically accurate, but the residual noise arising from removal clouds and other atmospheric and electronic effects can produce outliers that must be mitigated to properly exploit the remote sensing information. In this study, we show how ground-truth data from rain gauge stations can improve the quality of satellite imagery. To this end, a simulation study is conducted wherein different sizes of outlier outbreaks are spread and randomly introduced in the normalized difference vegetation index (NDVI and the day and night land surface temperature (LST of composite images from Navarre (Spain between 2011 and 2015. To remove outliers, a new method called thin-plate splines with covariates (TpsWc is proposed. This method consists of smoothing the median anomalies with a thin-plate spline model, whereby transformed ground-truth data are the external covariates of the model. The performance of the proposed method is measured with the square root of the mean square error (RMSE, calculated as the root of the pixel-by-pixel mean square differences between the original data and the predicted data with the TpsWc model and with a state-space model with and without covariates. The study shows that the use of ground-truth data reduces the RMSE in both the TpsWc model and the state-space model used for comparison purposes. The new method successfully removes the abnormal data while preserving the phenology of the raw data. The RMSE reduction percentage varies according to the derived variables (NDVI or LST, but reductions of up to 20% are achieved with the new proposal.

  13. Skepticism, truth as coherence, and constructivist epistemology: grounds for resolving the discord between science and religion?

    2010-03-01

    Science and religion exhibit multiple relationships as ways of knowing. These connections have been characterized as cousinly, mutually respectful, non-overlapping, competitive, proximate-ultimate, dominant-subordinate, and opposing-conflicting. Some of these ties create stress, and tension between science and religion represents a significant chapter in humans' cultural heritage before and since the Enlightenment. Truth, knowledge, and their relation are central to science and religion as ways of knowing, as social institutions, and to their interaction. In religion, truth is revealed through God's word. In science, truth is sought after via empirical methods. Discord can be viewed as a competition for social legitimization between two social institutions whose goals are explaining the world and how it works. Under this view, the root of the discord is truth as correspondence. In this concept of truth, knowledge corresponds to the facts of reality, and conflict is inevitable for many because humans want to ask which one—science or religion—gets the facts correct. But, the root paradox, also known as the problem of the criterion, suggests that seeking to know nature as it is represents a fruitless endeavor. The discord can be set on new ground and resolved by taking a moderately skeptical line of thought, one which employs truth as coherence and a moderate form of constructivist epistemology. Quantum mechanics and evolution as scientific theories and scientific research on human consciousness and vision provide support for this line of argument. Within a constructivist perspective, scientists would relinquish only the pursuit of knowing reality as it is. Scientists would retain everything else. Believers who hold that religion explains reality would come to understand that God never revealed His truth of nature; rather, He revealed His truth in how we are to conduct our lives.

    Upcoming multiyear satellite lidar aerosol observations need strong support by a worldwide ground-truth lidar network. In this context the question arises as to whether the ground stations can deliver the same results as obtained from space when the Klett formalism is applied to elastic backscatter lidar data for the same aerosol case. This question is investigated based on simulations of observed cases of simple and complex aerosol layering. The results show that the differences between spaceborne and ground-based observations can be as large as20% for the backscatter and extinction coefficients and the optimum estimates of the column lidar ratios. In cases with complex aerosol layering, the application of the two-layer approach can lead to similar results (space, ground) and accurate products provided that horizontally homogeneous aerosol conditions are given

    Quantitative assessments on the performance of automated cloud analysis algorithms require the creation of highly accurate, manual cloud, no cloud (CNC) images from multispectral meteorological satellite data. In general, the methodology to create ground truth analyses for the evaluation of cloud detection algorithms is relatively straightforward. However, when focus shifts toward quantifying the performance of automated cloud classification algorithms, the task of creating ground truth images becomes much more complicated since these CNC analyses must differentiate between water and ice cloud tops while ensuring that inaccuracies in automated cloud detection are not propagated into the results of the cloud classification algorithm. The process of creating these ground truth CNC analyses may become particularly difficult when little or no spectral signature is evident between a cloud and its background, as appears to be the case when thin cirrus is present over snow-covered surfaces. In this paper, procedures are described that enhance the researcher's ability to manually interpret and differentiate between thin cirrus clouds and snow-covered surfaces in daytime AVHRR imagery. The methodology uses data in up to six AVHRR spectral bands, including an additional band derived from the daytime 3.7 micron channel, which has proven invaluable for the manual discrimination between thin cirrus clouds and snow. It is concluded that while the 1.6 micron channel remains essential to differentiate between thin ice clouds and snow. However, this capability that may be lost if the 3.7 micron data switches to a nighttime-only transmission with the launch of future NOAA satellites.

    The number of subjects needed to establish the normative limits for visual field (VF) testing is not known. Using bootstrap resampling, we determined whether the ground truth mean, distribution limits, and standard deviation (SD) could be approximated using different set size ( x ) levels, in order to provide guidance for the number of healthy subjects required to obtain robust VF normative data. We analyzed the 500 Humphrey Field Analyzer (HFA) SITA-Standard results of 116 healthy subjects and 100 HFA full threshold results of 100 psychophysically experienced healthy subjects. These VFs were resampled (bootstrapped) to determine mean sensitivity, distribution limits (5th and 95th percentiles), and SD for different ' x ' and numbers of resamples. We also used the VF results of 122 glaucoma patients to determine the performance of ground truth and bootstrapped results in identifying and quantifying VF defects. An x of 150 (for SITA-Standard) and 60 (for full threshold) produced bootstrapped descriptive statistics that were no longer different to the original distribution limits and SD. Removing outliers produced similar results. Differences between original and bootstrapped limits in detecting glaucomatous defects were minimized at x = 250. Ground truth statistics of VF sensitivities could be approximated using set sizes that are significantly smaller than the original cohort. Outlier removal facilitates the use of Gaussian statistics and does not significantly affect the distribution limits. We provide guidance for choosing the cohort size for different levels of error when performing normative comparisons with glaucoma patients.

    Community structure is of paramount importance for the understanding of complex networks. Consequently, there is a tremendous effort in order to develop efficient community detection algorithms. Unfortunately, the issue of a fair assessment of these algorithms is a thriving open question. If the ground-truth community structure is available, various clustering-based metrics are used in order to compare it versus the one discovered by these algorithms. However, these metrics defined at the node level are fairly insensitive to the variation of the overall community structure. To overcome these limitations, we propose to exploit the topological features of the 'community graphs' (where the nodes are the communities and the links represent their interactions) in order to evaluate the algorithms. To illustrate our methodology, we conduct a comprehensive analysis of overlapping community detection algorithms using a set of real-world networks with known a priori community structure. Results provide a better perception of their relative performance as compared to classical metrics. Moreover, they show that more emphasis should be put on the topology of the community structure. We also investigate the relationship between the topological properties of the community structure and the alternative evaluation measures (quality metrics and clustering metrics). It appears clearly that they present different views of the community structure and that they must be combined in order to evaluate the effectiveness of community detection algorithms.

    Peer prediction mechanisms allow the truthful elicitation of private signals (e.g., experiences, or opinions) in regard to a true world state when this ground truth is unobservable. The original peer prediction method is incentive compatible for any number of agents n >= 2, but relies on a common prior, shared by all agents and the mechanism. The Bayesian Truth Serum (BTS) relaxes this assumption. While BTS still assumes that agents share a common prior, this prior need not be known to the me...

    Full Text Available The founder of modern logic and grandfather of analytic philosophy was 70 years old when he published his paper 'Der Gedanke' (The Thought in 1918. This essay contains some of Gottlob Frege's deepest and most provocative reflections on the concept of truth, and it will play a prominent role in my lectures. The plan for my lectures is as follows. What is it that is (primarily true or false? 'Thoughts', is Frege's answer. In §1, I shall explain and defend this answer. In §2, I shall briefly consider his enthymematic argument for the conclusion that the word 'true' resists any attempt at defining it. In §3, I shall discuss his thesis that the thought that things are thus and so is identical with the thought that it is true that things are thus and so. The reasons we are offered for this thesis will be found wanting. In §4, I shall comment extensively on Frege's claim that, in a non-formal language like the one I am currently trying to speak, we can say whatever we want to say without ever using the word 'true' or any of its synonyms. I will reject the propositional-redundancy claim, endorse the assertive-redundancy claim and deny the connection Frege ascribes to them. In his classic 1892 paper 'Über Sinn und Bedeutung' (On Sense and Signification Frege argues that truth-values are objects. In §5, I shall scrutinize his argument. In §6, I will show that in Frege's ideography (Begriffsschrift truth, far from being redundant, is omnipresent. The final §7 is again on truth-bearers, this time as a topic in the theory of intentionality and in metaphysics. In the course of discussing Frege's views on the objecthood, the objectivity of thoughts and the timelessness of truth(s, I will plead for a somewhat mitigated Platonism.

  4. Assessment of infrasound signals recorded on seismic stations and infrasound arrays in the western United States using ground truth sources

    2018-06-01

    Ground truth sources in Utah during 2003-2013 are used to assess the contribution of temporal atmospheric conditions to infrasound detection and the predictive capabilities of atmospheric models. Ground truth sources consist of 28 long duration static rocket motor burn tests and 28 impulsive rocket body demolitions. Automated infrasound detections from a hybrid of regional seismometers and infrasound arrays use a combination of short-term time average/long-term time average ratios and spectral analyses. These detections are grouped into station triads using a Delaunay triangulation network and then associated to estimate phase velocity and azimuth to filter signals associated with a particular source location. The resulting range and azimuth distribution from sources to detecting stations varies seasonally and is consistent with predictions based on seasonal atmospheric models. Impulsive signals from rocket body detonations are observed at greater distances (>700 km) than the extended duration signals generated by the rocket burn test (up to 600 km). Infrasound energy attenuation associated with the two source types is quantified as a function of range and azimuth from infrasound amplitude measurements. Ray-tracing results using Ground-to-Space atmospheric specifications are compared to these observations and illustrate the degree to which the time variations in characteristics of the observations can be predicted over a multiple year time period.

    2011-05-01

    Light detection and ranging (LIDAR) systems have demonstrated some capability to meet the needs of a fastresponse standoff biological detection method for simulants in open air conditions. These systems are designed to exploit various cloud signatures, such as differential elastic backscatter, fluorescence, and depolarization in order to detect biological warfare agents (BWAs). However, because the release of BWAs in open air is forbidden, methods must be developed to predict candidate system performance against real agents. In support of such efforts, the Johns Hopkins University Applied Physics Lab (JHU/APL) has developed a modeling approach to predict the optical properties of agent materials from relatively simple, Biosafety Level 3-compatible bench top measurements. JHU/APL has fielded new ground truth instruments (in addition to standard particle sizers, such as the Aerodynamic particle sizer (APS) or GRIMM aerosol monitor (GRIMM)) to more thoroughly characterize the simulant aerosols released in recent field tests at Dugway Proving Ground (DPG). These instruments include the Scanning Mobility Particle Sizer (SMPS), the Ultraviolet Aerodynamic Particle Sizer (UVAPS), and the Aspect Aerosol Size and Shape Analyser (Aspect). The SMPS was employed as a means of measuring smallparticle concentrations for more accurate Mie scattering simulations; the UVAPS, which measures size-resolved fluorescence intensity, was employed as a path toward fluorescence cross section modeling; and the Aspect, which measures particle shape, was employed as a path towards depolarization modeling.

  6. Evaluation of event-based algorithms for optical flow with ground-truth from inertial measurement sensor

    2016-04-01

    Full Text Available In this study we compare nine optical flow algorithms that locally measure the flow normal to edges according to accuracy and computation cost. In contrast to conventional, frame-based motion flow algorithms, our open-source implementations compute optical flow based on address-events from a neuromorphic Dynamic Vision Sensor (DVS. For this benchmarking we created a dataset of two synthesized and three real samples recorded from a 240x180 pixel Dynamic and Active-pixel Vision Sensor (DAVIS. This dataset contains events from the DVS as well as conventional frames to support testing state-of-the-art frame-based methods. We introduce a new source for the ground truth: In the special case that the perceived motion stems solely from a rotation of the vision sensor around its three camera axes, the true optical flow can be estimated using gyro data from the inertial measurement unit integrated with the DAVIS camera. This provides a ground-truth to which we can compare algorithms that measure optical flow by means of motion cues. An analysis of error sources led to the use of a refractory period, more accurate numerical derivatives and a Savitzky-Golay filter to achieve significant improvements in accuracy. Our pure Java implementations of two recently published algorithms reduce computational cost by up to 29% compared to the original implementations. Two of the algorithms introduced in this paper further speed up processing by a factor of 10 compared with the original implementations, at equal or better accuracy. On a desktop PC, they run in real-time on dense natural input recorded by a DAVIS camera.

    While long-term objectives of monitoring and verification regimes include remote characterization and discrimination of surficial geologic and topographic features at sites of interest, ground truth data is required to advance development of remote sensing techniques. Increasingly, it is desirable for these ground-based or ground-proximal characterization methodologies to be as nimble, efficient, non-invasive, and non-destructive as their higher-altitude airborne counterparts while ideally providing superior resolution. For this study, the area of interest is an alluvial site at the Nevada National Security Site intended for use in the Source Physics Experiment's (Snelson et al., 2013) second phase. Ground-truth surface topographic characterization was performed using a DJI Inspire 1 unmanned aerial system (UAS), at very low altitude (clouds. Within the area of interest, careful installation of surveyed ground control fiducial markers supplied necessary targets for field collection, and information for model georectification. The resulting model includes a Digital Elevation Model derived from 2D imagery. It is anticipated that this flexible and versatile characterization process will provide point cloud data resolution equivalent to a purely ground-based LiDAR scanning deployment (e.g., 1-2cm horizontal and vertical resolution; e.g., Sussman et al., 2012; Schultz-Fellenz et al., 2013). In addition to drastically increasing time efficiency in the field, the UAS method also allows for more complete coverage of the study area when compared to ground-based LiDAR. Comparison and integration of these data with conventionally-acquired airborne LiDAR data from a higher-altitude (~ 450m) platform will aid significantly in the refinement of technologies and detection capabilities of remote optical systems to identify and detect surface geologic and topographic signatures of interest. This work includes a preliminary comparison of surface signatures detected from varying

    Developing nutrition-focused environmental interventions for youth requires accurate assessment of where they purchase food. We have developed an innovative, technology-based method to improve the accuracy of food source recall among children using a tablet PC and ground-truthing methodologies. As part of the B'more Healthy Communties for Kids study, we mapped and digitally photographed every food source within a half-mile radius of 14 Baltimore City recreation centers. This food source database was then used with children from the surrounding neighborhoods to search for and identify the food sources they frequent. This novel integration of traditional data collection and technology enables researchers to gather highly accurate information on food source usage among children in Baltimore City. Funding is provided by the NICHD U-54 Grant #1U54HD070725-02.

    1974-01-01

    The author has identified the following significant results. A new device, called a Spectral Attenuation Board, has been designed and tested, which enables ERTS-1 sea truth collection teams to monitor the attenuation depths of three colors continuously, as the board is being towed behind a boat. The device consists of a 1.2 x 1.2 meter flat board held below the surface of the water at a fixed angle to the surface of the water. A camera mounted above the water takes photographs of the board. The resulting film image is analyzed by a micro-densitometer trace along the descending portion of the board. This yields information on the rate of attenuation of light penetrating the water column and the Secchi depth. Red and green stripes were painted on the white board to approximate band 4 and band 5 of the ERTS MSS so that information on the rate of light absorption by the water column of light in these regions of the visible spectrum could be concurrently measured. It was found that information from a red, green, and white stripe may serve to fingerprint the composition of the water mass. A number of these devices, when automated, could also be distributed over a large region to provide a cheap method of obtaining valuable satellite ground truth data at present time intervals.

  11. Hanford site ground water protection management plan

    International Nuclear Information System (INIS)

    1994-10-01

    Ground water protection at the Hanford Site consists of preventative and remedial measures that are implemented in compliance with a variety of environmental regulations at local, state, and federal levels. These measures seek to ensure that the resource can sustain a broad range of beneficial uses. To effectively coordinate and ensure compliance with applicable regulations, the U.S. Department of Energy has issued DOE Order 5400.1 (DOE 1988a). This order requires all U.S. Department of Energy facilities to prepare separate ground water protection program descriptions and plans. This document describes the Ground Water Protection Management Plan (GPMP) for the Hanford Site located in the state of Washington. DOE Order 5400.1 specifies that the GPMP covers the following general topical areas: (1) documentation of the ground water regime; (2) design and implementation of a ground water monitoring program to support resource management and comply with applicable laws and regulations; (3) a management program for ground water protection and remediation; (4) a summary and identification of areas that may be contaminated with hazardous waste; (5) strategies for controlling hazardous waste sources; (6) a remedial action program; and (7) decontamination, decommissioning, and related remedial action requirements. Many of the above elements are currently covered by existing programs at the Hanford Site; thus, one of the primary purposes of this document is to provide a framework for coordination of existing ground water protection activities. The GPMP provides the ground water protection policy and strategies for ground water protection/management at the Hanford Site, as well as an implementation plan to improve coordination of site ground water activities

    2002-01-01

    Surface water temperatures calculated from Multispectral Thermal Imager (MTI) brightness temperatures and the robust retrieval algorithm, developed by the Los Alamos National Laboratory (LANL), are compared with ground truth measurements at the Squaw Creek reservoir at the Comanche Peak Steam Electric Station near Granbury Texas. Temperatures calculated for thirty-four images covering the period May 2000 to March 2002 are compared with water temperatures measured at 10 instrumented buoy locations supplied by the Savannah River Technology Center. The data set was used to examine the effect of image quality on temperature retrieval as well as to document any bias between the sensor chip arrays (SCA's). A portion of the data set was used to evaluate the influence of proximity to shoreline on the water temperature retrievals. This study found errors in daytime water temperature retrievals of 1.8 C for SCA 2 and 4.0 C for SCA 1. The errors in nighttime water temperature retrievals were 3.8 C for SCA 1. Water temperature retrievals for nighttime appear to be related to image quality with the largest positive bias for the highest quality images and the largest negative bias for the lowest quality images. The daytime data show no apparent relationship between water temperature retrieval error and image quality. The average temperature retrieval error near open water buoys was less than corresponding values for the near-shore buoys. After subtraction of the estimated error in the ground truth data, the water temperature retrieval error was 1.2 C for the open-water buoys compared to 1.8 C for the near-shore buoys. The open-water error is comparable to that found at Nauru

    The Pacific Northwest Laboratory performs ground-water sampling activities at the US Department of Energy's (DOE's) Hanford Site in support of DOE's environmental surveillance responsibilities. The purpose of this document is to translate DOE's General Environmental Protection Program (DOE Order 5400.1) into a comprehensive ground-water sample collection and analysis plan for the Hanford Site. This sample collection and analysis plan sets forth the environmental surveillance objectives applicable to ground water, identifies the strategy for selecting sample collection locations, and lists the analyses to be performed to meet those objectives

  14. Behavioral pragmatism: No place for reality and truth

    Science.gov (United States)

    Barnes-Holmes, Dermot

    2000-01-01

    The current article begins by reviewing L. J. Hayes's claim that pragmatism relies on a correspondence-based truth criterion. To evaluate her claim, the concept of the observation sentence, proposed by the pragmatist philosopher W. V. Quine, is examined. The observation sentence appears to remove the issue of correspondence from Quine's pragmatist philosophy. Nevertheless, the issue of correspondence reemerges, as the problem of homology, when Quine appeals to agreement between or among observation sentences as the basis for truth. Quine also argues, however, that the problem of homology (i.e., correspondence) should be ignored on pragmatic grounds. Because the problem is simply ignored, but not resolved, there appears to be some substance to Hayes's claim that pragmatism relies ultimately on correspondence as a truth criterion. Behavioral pragmatism is then introduced to circumvent both Hayes's claim and Quine's implicit appeal to correspondence. Behavioral pragmatism avoids correspondence by appealing to the personal goals (i.e., the behavior) of the scientist or philosopher as the basis for establishing truth. One consequence of this approach, however, is that science and philosophy are robbed of any final or absolute objectives and thus may not be a satisfactory solution to philosophers. On balance, behavioral pragmatism avoids any appeal to correspondence-based truth, and thus it cannot be criticized for generating the same philosophical problems that have come to be associated with this truth criterion.

  15. Unveiling the truth: warnings reduce the repetition-based truth effect.

    Typically, people are more likely to consider a previously seen or heard statement as true compared to a novel statement. This repetition-based "truth effect" is thought to rely on fluency-truth attributions as the underlying cognitive mechanism. In two experiments, we tested the nature of the fluency-attribution mechanism by means of warning instructions, which informed participants about the truth effect and asked them to prevent it. In Experiment 1, we instructed warned participants to consider whether a statement had already been presented in the experiment to avoid the truth effect. However, warnings did not significantly reduce the truth effect. In Experiment 2, we introduced control questions and reminders to ensure that participants understood the warning instruction. This time, warning reduced, but did not eliminate the truth effect. Assuming that the truth effect relies on fluency-truth attributions, this finding suggests that warned participants could control their attributions but did not disregard fluency altogether when making truth judgments. Further, we found no evidence that participants overdiscount the influence of fluency on their truth judgments.

    Parks, Connie L; Monson, Keith L

    2018-05-01

    This study employed an automated facial recognition system as a means of objectively evaluating biometric correspondence between a ReFace facial approximation and the computed tomography (CT) derived ground truth skin surface of the same individual. High rates of biometric correspondence were observed, irrespective of rank class (R k ) or demographic cohort examined. Overall, 48% of the test subjects' ReFace approximation probes (n=96) were matched to his or her corresponding ground truth skin surface image at R 1 , a rank indicating a high degree of biometric correspondence and a potential positive identification. Identification rates improved with each successively broader rank class (R 10 =85%, R 25 =96%, and R 50 =99%), with 100% identification by R 57 . A sharp increase (39% mean increase) in identification rates was observed between R 1 and R 10 across most rank classes and demographic cohorts. In contrast, significantly lower (p0.05) performance differences were observed across demographic cohorts or CT scan protocols. Performance measures observed in this research suggest that ReFace approximations are biometrically similar to the actual faces of the approximated individuals and, therefore, may have potential operational utility in contexts in which computerized approximations are utilized as probes in automated facial recognition systems.

  2. Evaluation of digital image correlation techniques using realistic ground truth speckle images

    International Nuclear Information System (INIS)

    Cofaru, C; Philips, W; Van Paepegem, W

    2010-01-01

    Digital image correlation (DIC) has been acknowledged and widely used in recent years in the field of experimental mechanics as a contactless method for determining full field displacements and strains. Even though several sub-pixel motion estimation algorithms have been proposed in the literature, little is known about their accuracy and limitations in reproducing complex underlying motion fields occurring in real mechanical tests. This paper presents a new method for evaluating sub-pixel motion estimation algorithms using ground truth speckle images that are realistically warped using artificial motion fields that were obtained following two distinct approaches: in the first, the horizontal and vertical displacement fields are created according to theoretical formulas for the given type of experiment while the second approach constructs the displacements through radial basis function interpolation starting from real DIC results. The method is applied in the evaluation of five DIC algorithms with results indicating that the gradient-based DIC methods generally have a quality advantage when using small sized blocks and are a better choice for calculating very small displacements and strains. The Newton–Raphson is the overall best performing method with a notable quality advantage when large block sizes are employed and in experiments where large strain fields are of interest

    Full Text Available Brunei Bay, which receives freshwater discharge from four major rivers, namely Limbang, Sundar, Weston and Menumbok, hosts a luxuriant mangrove cover in East Malaysia. However, this relatively undisturbed mangrove forest has been less scientifically explored, especially in terms of vegetation structure, ecosystem services and functioning, and land-use/cover changes. In the present study, mangrove areal extent together with species composition and distribution at the four notified estuaries was evaluated through remote sensing (Advanced Land Observation Satellite—ALOS and ground-truth (Point-Centred Quarter Method—PCQM observations.

The medium resolution ALOS data were efficient for mapping dominant mangrove species such as Nypa fruticans, Rhizophora apiculata, Sonneratia caseolaris, S. alba and Xylocarpus granatum in the vicinity (accuracy: 80%. The PCQM estimates found a higher basal area at Limbang and Menumbok—suggestive of more mature vegetation, compared to Sundar and Weston. Mangrove stand structural complexity (derived from the complexity index was also high in the order of Limbang > Menumbok > Sundar > Weston and supporting the perspective of less/undisturbed vegetation at two former locations.

The results from this study would be able to serve as strong baseline data for future mangrove investigations at Brunei Bay, including for monitoring and management purposes locally at present.

    We seek to combine high-resolution remotely sensed data with models and ground truth measurements, in the context of a Geographical Information System, integrated with specialized image processing software. We will use this integrated system to analyze the data from two Case Studies, one at a bore Al forest site, the other a tropical forest site. We will assess the information content of the different components of the data, determine the optimum data combinations to study biogeophysical changes in the forest, assess the best way to visualize the results, and validate the models for the forest response to different radar wavelengths/polarizations. During the 1990's, unprecedented amounts of high-resolution images from space of the Earth's surface will become available to the applications scientist from the LANDSAT/TM series, European and Japanese ERS-1 satellites, RADARSAT and SIR-C missions. When the Earth Observation Systems (EOS) program is operational, the amount of data available for a particular site can only increase. The interdisciplinary scientist, seeking to use data from various sensors to study his site of interest, may be faced with massive difficulties in manipulating such large data sets, assessing their information content, determining the optimum combinations of data to study a particular parameter, visualizing his results and validating his model of the surface. The techniques to deal with these problems are also needed to support the analysis of data from NASA's current program of Multi-sensor Airborne Campaigns, which will also generate large volumes of data. In the Case Studies outlined in this proposal, we will have somewhat unique data sets. For the Bonanza Creek Experimental Forest (Case I) calibrated DC-8 SAR data and extensive ground truth measurement are already at our disposal. The data set shows documented evidence to temporal change. The Belize Forest Experiment (Case II) will produce calibrated DC-8 SAR and AVIRIS data, together with

    2000-11-16

    This plan has been prepared in response to direction from the U.S. Department of Energy. The purpose of the plan is to define approaches that will be implemented to ensure protection of the public and the environment when active Low-Level Burial Grounds (LLBGs) at the Hanford Site are closed. Performance assessments for active burial grounds in the 200 East and West 200 Areas provide current estimates of potential environmental contamination and doses to the ''maximum exposed individual'' from burial ground operation and closure and compare dose estimates to performance objective dose limits for the facilities. This is an Operational Closure Plan. The intent of the guidance in DOE Order 435.1 is that this plan will be a living document, like the facility performance assessments, and will be revised periodically through the operational life of the LLBGs to reflect updated information on waste inventory. management practices, facility transition planning, schedule dates, assessments of post-closure performance, and environmental consequences. Out year dates identified in this plan are tentative. A Final Closure Plan will be prepared in the future when the timing and extent of closure-related activities for LLBGs can be established with greater certainty. After current operations at the LLBGs are concluded, this plan proposes transitioning of these facilities to the Environmental Restoration Program. This action will enable the Environmental Restoration Program to design and implement consistent and coordinated final remedial actions for active and inactive LLBGs. Active and inactive burial grounds in the 200 West and 200 East Areas are commingled. This plan describes approaches that will be implemented during Interim Closure, Final Closure, and Institutional Control Periods to prepare LLBGs for surface barriers, and the construction of barriers, as well as the scope of inspection, monitoring and maintenance practices that will be performed during

    The Southwest U.S. Seismo-Acoustic Network (SUSSAN) is a collaborative project designed to produce infrasound event detection bulletins for the infrasound community for research purposes. We are aggregating a large, unique, near real-time data set with available ground truth information from seismo-acoustic arrays across New Mexico, Utah, Nevada, California, Texas and Hawaii. The data are processed in near real-time (~ every 20 minutes) with detections being made on individual arrays and locations determined for networks of arrays. The detection and location data are then combined with any available ground truth information and compiled into a bulletin that will be released to the general public directly and eventually through the IRIS infrasound event bulletin. We use the open source Earthworm seismic data aggregation software to acquire waveform data either directly from the station operator or via the Incorporated Research Institutions for Seismology Data Management Center (IRIS DMC), if available. The data are processed using InfraMonitor, a powerful infrasound event detection and localization software program developed by Stephen Arrowsmith at Los Alamos National Laboratory (LANL). Our goal with this program is to provide the infrasound community with an event database that can be used collaboratively to study various natural and man-made sources. We encourage participation in this program directly or by making infrasound array data available through the IRIS DMC or other means. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

  9. Enhanced Site Characterization of the 618-4 Burial Ground

    Energy Technology Data Exchange (ETDEWEB)

    Murray, Christopher J.; Last, George V.; Chien, Yi-Ju

    2001-09-25

    This report describes the results obtained from deployment of the Enhanced Site Characterization System (ESCS) at the Hanford Site's 618-4 Burial Ground. The objective of this deployment was to use advanced geostatistical methods to integrate and interpret geophysical and ground truth data, to map the physical types of waste materials present in unexcavated portions of the burial ground. One issue of particularly interest was the number of drums (containing depleted uranium metal shavings or uranium-oxide powder) remaining in the burial ground and still requiring removal.Fuzzy adaptive resonance theory (ART), a neural network classification method, was used to cluster the study area into 3 classes based on their geophysical signatures. Multivariate statistical analyses and discriminant function analysis (DFA) indicated that the drum area as well as a second area (the SW anomaly) had similar geophysical signatures that were different from the rest of the burial ground. Further analysis of the drum area suggested that as many as 770 drums to 850 drums may remain in that area. Similarities between the geophysical signatures of the drum area and the SW anomaly suggested that excavation of the SW anomaly area also proceed with caution.Deployment of the ESCS technology was successful in integrating multiple geophysical variables and grouping these observations into clusters that are relevant for planning further excavation of the buried ground. However, the success of the technology could not be fully evaluated because reliable ground truth data were not available to enable calibration of the different geophysical signatures against actual waste types.

    2013-01-01

    A Web application facilitates collaborative development of the ground operations planning document. This will reduce costs and development time for new programs by incorporating the data governance, access control, and revision tracking of the ground operations planning data. Ground Operations Planning requires the creation and maintenance of detailed timelines and documentation. The GOPDb Web application was created using state-of-the-art Web 2.0 technologies, and was deployed as SaaS (Software as a Service), with an emphasis on data governance and security needs. Application access is managed using two-factor authentication, with data write permissions tied to user roles and responsibilities. Multiple instances of the application can be deployed on a Web server to meet the robust needs for multiple, future programs with minimal additional cost. This innovation features high availability and scalability, with no additional software that needs to be bought or installed. For data governance and security (data quality, management, business process management, and risk management for data handling), the software uses NAMS. No local copy/cloning of data is permitted. Data change log/tracking is addressed, as well as collaboration, work flow, and process standardization. The software provides on-line documentation and detailed Web-based help. There are multiple ways that this software can be deployed on a Web server to meet ground operations planning needs for future programs. The software could be used to support commercial crew ground operations planning, as well as commercial payload/satellite ground operations planning. The application source code and database schema are owned by NASA.

    1977-01-01

    A land use map of a five county area in North Alabama was generated from LANDSAT data using a supervised classification algorithm. There was good overall agreement between the land use designated and known conditions, but there were also obvious discrepancies. In ground checking the map, two types of errors were encountered - shift and misclassification - and a method was developed to eliminate or greatly reduce the errors. Randomly selected study areas containing 2,525 pixels were analyzed. Overall, 76.3 percent of the pixels were correctly classified. A contingency coefficient of correlation was calculated to be 0.7 which is significant at the alpha = 0.01 level. The land use maps generated by computers from LANDSAT data are useful for overall land use by regional agencies. However, care must be used when making detailed analysis of small areas. The procedure used for conducting the ground truth study together with data from representative study areas is presented.

    The paper reviews NASA planning in the fields of ground, launch and flight operations and experiment integration to effectively operate Spacelab. Payload mission planning is discussed taking consideration of orbital analysis and the mission of a multiuser payload which may be either single or multidiscipline. Payload analytical integration - as active process of analyses to ensure that the experiment payload is compatible to the mission objectives and profile ground and flight operations and that the resource demands upon Spacelab can be satisfied - is considered. Software integration is touched upon and the major integration levels in ground operational processing of Spacelab and its experimental payloads are examined. Flight operations, encompassing the operation of the Space Transportation System and the payload, are discussed as are the initial Spacelab missions. Charts and diagrams are presented illustrating the various planning areas.

    This plan presents background information and a working guide to assist Mine Operations and Engineering in developing strategies for addressing ground control issues at the Waste Isolation Pilot Plant (WIPP). With the anticipated receipt of waste in late 1997, this document provides additional detail to Panel 1 activities and options. The plan also serves as a foundation document for development and revision of the annual long-term ground control plan. Section 2.0 documents the current status of all underground excavations with respect to location, geology, geometry, age, ground support, operational use, projected life, and physical conditions. Section 3.0 presents the methods used to evaluate ground conditions, including visual observations of the roof, ribs, and floor, inspection of observation holes, and review of instrumentation data. Section 4.0 lists several ground support options and specific applications of each. Section 5.0 discusses remedial ground control measures that have been implemented to date. Section 6.0 presents projections and recommendations for ground control actions based on the information in Sections 2.0 through 5.0 of this plan and on a rating of the critical nature of each specific area. Section 7.0 presents a summary statement, and Section 8.0 includes references. Appendix A provides an overview and critique of ground control systems that have been, or may be, used at the site. Because of the dynamic nature of the underground openings and associated geotechnical activities, this plan will be revised as additional data are incorporated

    Full Text Available What does it mean to assert that Wikipedia has a relation to truth? That there is, despite regular claims to the contrary, an entire apparatus of truth in Wikipedia? In this article, I show that Wikipedia has in fact two distinct relations to truth: one which is well known and forms the basis of existing popular and scholarly commentaries, and another which refers to equally well-known aspects of Wikipedia, but has not been understood in terms of truth. I demonstrate Wikipedia's dual relation to truth through a close analysis of the Neutral Point of View core content policy (and one of the project's 'Five Pillars'. I conclude by indicating what is at stake in the assertion that Wikipedia has a regime of truth and what bearing this has on existing commentaries.

  16. Ground-Truthing of Airborne LiDAR Using RTK-GPS Surveyed Data in Coastal Louisiana's Wetlands

    Science.gov (United States)

    2017-12-01

    Airborne LiDAR (Light Detection and Ranging) data are used by engineers and scientists to create bare earth digital elevation models (DEM), which are essential to modeling complex coastal, ecological, and hydrological systems. However, acquiring accurate bare earth elevations in coastal wetlands is difficult due to the density of marsh grasses that prevent the sensors reflection off the true ground surface. Previous work by Medeiros et al. [2015] developed a technique to assess LiDAR error and adjust elevations according to marsh vegetation density and index. The aim of this study is the collection of ground truth points and the investigation on the range of potential errors found in existing LiDAR datasets within coastal Louisiana's wetlands. Survey grids were mapped out in an area dominated by Spartina alterniflora and a survey-grade Trimble Real Time Kinematic (RTK) GPS device was employed to measure bare earth ground elevations in the marsh system adjacent to Terrebonne Bay, LA. Elevations were obtained for 20 meter-spaced surveyed grid points and were used to generate a DEM. The comparison between LiDAR derived and surveyed data DEMs yield an average difference of 23 cm with a maximum difference of 68 cm. Considering the local tidal range of 45 cm, these differences can introduce substantial error when the DEM is used for ecological modeling [Alizad et al., 2016]. Results from this study will be further analyzed and implemented in order to adjust LiDAR-derived DEMs closer to their true elevation across Louisiana's coastal wetlands. ReferencesAlizad, K., S. C.

  19. Towards ground-truthing of spaceborne estimates of above-ground biomass and leaf area index in tropical rain forests

    The canopy height of forests is a key variable which can be obtained using air- or spaceborne remote sensing techniques such as radar interferometry or lidar. If new allometric relationships between canopy height and the biomass stored in the vegetation can be established this would offer the possibility for a global monitoring of the above-ground carbon content on land. In the absence of adequate field data we use simulation results of a tropical rain forest growth model to propose what degree of information might be generated from canopy height and thus to enable ground-truthing of potential future satellite observations. We here analyse the correlation between canopy height in a tropical rain forest with other structural characteristics, such as above-ground biomass (AGB) (and thus carbon content of vegetation) and leaf area index (LAI). The process-based forest growth model FORMIND2.0 was applied to simulate (a) undisturbed forest growth and (b) a wide range of possible disturbance regimes typically for local tree logging conditions for a tropical rain forest site on Borneo (Sabah, Malaysia) in South-East Asia. It is found that for undisturbed forest and a variety of disturbed forests situations AGB can be expressed as a power-law function of canopy height h (AGB=a·hb) with an r2~60% for a spatial resolution of 20 m×20 m (0.04 ha, also called plot size). The regression is becoming significant better for the hectare wide analysis of the disturbed forest sites (r2=91%). There seems to exist no functional dependency between LAI and canopy height, but there is also a linear correlation (r2~60%) between AGB and the area fraction in which the canopy is highly disturbed. A reasonable agreement of our results with observations is obtained from a comparison of the simulations with permanent sampling plot data from the same region and with the large-scale forest inventory in Lambir. We conclude that the spaceborne remote sensing techniques have the potential to

After clarifying how this concept is used in classical logic, through the notions of truth-table, truth-function and bivaluation, we examine some generalizations of it in non-classical logics: many-valued matrix semantics with three and four values, non-truth-functional bivalent semantics, Kripke possible world semantics.

  1. Maneuver Planning for Conjunction Risk Mitigation with Ground-track Control Requirements

    2008-01-01

    The planning of conjunction Risk Mitigation Maneuvers (RMM) in the presence of ground-track control requirements is analyzed. Past RMM planning efforts on the Aqua, Aura, and Terra spacecraft have demonstrated that only small maneuvers are available when ground-track control requirements are maintained. Assuming small maneuvers, analytical expressions for the effect of a given maneuver on conjunction geometry are derived. The analytical expressions are used to generate a large trade space for initial RMM design. This trade space represents a significant improvement in initial maneuver planning over existing methods that employ high fidelity maneuver models and propagation.

  2. Truth Obviousness in Ancient Greek Philosophy

    Directory of Open Access Journals (Sweden)

    Halyna I. Budz

    2013-01-01

    Full Text Available The article examines the features of the axiomatic approach to the truth understanding in ancient Greek philosophy. Truth in the works by ancient philosophers has axiomatic essence, basing on divine origin of truth. As the truth has a divine origin, it is in reality. The reality, created by Gods is the solemn reality. Therefore, understanding of reality by man is the display of divine reality, which is true and clever. In of the context of ancient Greek philosophy, to know truth is to know something, existing in reality, in other words, something, truly existing, eternal reality. Consequently, to know truth is it to know the substantial reality base. That’s why the justification of the reality origin is the axiomatic doctrine of truth at the same time, because only fundamental principle “truly” exists and is the truth itself. The idea of fundamental principle in ancient Greek philosophy is the axiom, universal principle, which is the base of reality as a substance from ontological perspective and is realized as the truth from gnosiological perspective. Fundamental principle, as Greeks understand it, coincides with the truth, in other words, reality and thinking are identical. The idea of reality source is the universal criterion of world perception at the same time, in other words, it is the truth, which is perceived axiomatically.

    The purpose of this study was the generation of ground truth files (GTFs) of the breast ducts from 3D images of the Invenia™ Automated Breast Ultrasound System (ABUS) system (GE Healthcare, Little Chalfont, UK) and the application of these GTFs for the optimization of the imaging protocol and the evaluation of a computer aided detection (CADe) algorithm developed for automated duct detection. Six lactating, nursing volunteers were scanned with the ABUS before and right after breastfeeding their infants. An expert in breast ultrasound generated rough outlines of the milk-filled ducts in the transaxial slices of all image volumes and the final GTFs were created by using thresholding and smoothing tools in ImageJ. In addition, a CADe algorithm automatically segmented duct like areas and its results were compared to the expert’s GTFs by estimating true positive fraction (TPF) or % overlap. The CADe output differed significantly from the expert’s but both detected a smaller than expected volume of the ducts due to insufficient contrast (ducts were partially filled with milk), discontinuities, and artifacts. GTFs were used to modify the imaging protocol and improve the CADe method. In conclusion, electronic GTFs provide a valuable tool in the optimization of a tomographic imaging system, the imaging protocol, and the CADe algorithms. Their generation, however, is an extremely time consuming, strenuous process, particularly for multi-slice examinations, and alternatives based on phantoms or simulations are highly desirable.

  7. An existential theory of truth

    1993-01-01

    Full Text Available This article is an attempt to present a simplified account of the theory of truth expressed in the writings of certain existentialist writers - namely, Kierkegaard, Heidegger, Jaspers, and Marcel. It is designed to serve as a supplement to conventional textbook treatments of the nature of truth, which typically ignore the contributions that existentialists have made to the topic. An existential theory of truth stresses the epistemological (not ontological indeterminateness of meaning and truth, apart from one’s personal participation in determining them. Contrary to superficial interpretations, this theory does not do away either with a transcendent reality or with objectivity. What is rejected is anything that would circumvent the necessary task of participating, oneself, in the epistemological determination of truth.

    Electric utilities collect large volumes of data at every level of their business, including SCADA, Smart Metering and Smart Grid initiatives, LIDAR and other 3D imagery surveys. Different types of database systems are used to store the information, rendering data flow within the utility business process extremely complicated. The industry trend has been to endure redundancy of data input and maintenance of multiple copies of the same data across different solution data sets. Efforts have been made to improve the situation with point to point interfaces, but with the tools and solutions available today, a single point of truth can be achieved. Consolidated and validated data can be published into a data warehouse at the right point in the process, making the information available to all other enterprise systems and solutions. This paper explained how the single point of truth spatial data warehouse and process automation services can be configured to streamline the flow of data within the utility business process using the initiate-plan-execute-close (IPEC) utility workflow model. The paper first discussed geospatial challenges faced by utilities and then presented the approach and technology aspects. It was concluded that adoption of systems and solutions that can function with and be controlled by the IPEC workflow can provide significant improvement for utility operations, particularly if those systems are coupled with the spatial data warehouse that reflects a single point of truth. 6 refs., 3 figs.

  10. THEOLOGICAL AND PHILOSOPHICAL THEORIES OF TRUTH

    Directory of Open Access Journals (Sweden)

    Hans-Peter Grosshans

    2012-02-01

    Full Text Available Examining some theological and philosophical theories of truth, the author concentrates his attention on the experience of giving concrete reality to the Christian discourse about truth and at the same time contrasting this search with the attempts of philosophy to define truth. He draws the reader’s attention to the understanding of truth in language and communication. In his article he discusses the essential theories of truth which are characteristic of western philosophy: classical, correspondent, coherent, pragmatic, communicative and ontic. The author notes the specific traits of a theological understanding of truth and contends that it is based on an ontologically higher level than that of the classic definition of truth viewed simply in relation to reality and the understanding. The knowledge of God given to the Christian faith by the activity of the triune God, is in itself perfect and therefore in no need of further development. It is on this basis that theology develops its knowledge of faith, sweeping aside everything which is not in accord with this fundamental affirmation of faith or with the witness of revealed truth

  12. An Empirical Study of Atmospheric Correction Procedures for Regional Infrasound Amplitudes with Ground Truth.

    Howard, J. E.

    2014-12-01

    This study focusses on improving methods of accounting for atmospheric effects on infrasound amplitudes observed on arrays at regional distances in the southwestern United States. Recordings at ranges of 150 to nearly 300 km from a repeating ground truth source of small HE explosions are used. The explosions range in actual weight from approximately 2000-4000 lbs. and are detonated year-round which provides signals for a wide range of atmospheric conditions. Three methods of correcting the observed amplitudes for atmospheric effects are investigated with the data set. The first corrects amplitudes for upper stratospheric wind as developed by Mutschlecner and Whitaker (1999) and uses the average wind speed between 45-55 km altitudes in the direction of propagation to derive an empirical correction formula. This approach was developed using large chemical and nuclear explosions and is tested with the smaller explosions for which shorter wavelengths cause the energy to be scattered by the smaller scale structure of the atmosphere. The second approach isa semi-empirical method using ray tracing to determine wind speed at ray turning heights where the wind estimates replace the wind values in the existing formula. Finally, parabolic equation (PE) modeling is used to predict the amplitudes at the arrays at 1 Hz. The PE amplitudes are compared to the observed amplitudes with a narrow band filter centered at 1 Hz. An analysis is performed of the conditions under which the empirical and semi-empirical methods fail and full wave methods must be used.

    The NASA Orion Ground Processing Team was originally formed by the Kennedy Space Center (KSC) Constellation (Cx) Project Office's Orion Division to define, refine and mature pre-launch and post-landing ground operations for the Orion human spacecraft. The multidisciplined KSC Orion team consisted of KSC civil servant, SAIC, Productivity Apex, Inc. and Boeing-CAPPS engineers, project managers and safety engineers, as well as engineers from Constellation's Orion Project and Lockheed Martin Orion Prime contractor. The team evaluated the Orion design configurations as the spacecraft concept matured between Systems Design Review (SDR), Systems Requirement Review (SRR) and Preliminary Design Review (PDR). The team functionally decomposed prelaunch and post-landing steps at three levels' of detail, or tiers, beginning with functional flow block diagrams (FFBDs). The third tier FFBDs were used to build logic networks and nominal timelines. Orion ground support equipment (GSE) was identified and mapped to each step. This information was subsequently used in developing lower level operations steps in a Ground Operations Planning Document PDR product. Subject matter experts for each spacecraft and GSE subsystem were used to define 5th - 95th percentile processing times for each FFBD step, using the Delphi Method. Discrete event simulations used this information and the logic network to provide processing timeline confidence intervals for launch rate assessments. The team also used the capabilities of the KSC Visualization Lab, the FFBDs and knowledge of the spacecraft, GSE and facilities to build visualizations of Orion pre-launch and postlanding processing at KSC. Visualizations were a powerful tool for communicating planned operations within the KSC community (i.e., Ground Systems design team), and externally to the Orion Project, Lockheed Martin spacecraft designers and other Constellation Program stakeholders during the SRR to PDR timeframe.

  16. The vital role of transcendental truth in science.

    Charlton, Bruce G

    2009-04-01

    I have come to believe that science depends for its long-term success on an explicit and pervasive pursuit of the ideal of transcendental truth. 'Transcendental' implies that a value is ideal and ultimate - it is aimed-at but can only imperfectly be known, achieved or measured. So, transcendental truth is located outside of science; beyond scientific methods, processes and peer consensus. Although the ultimate scientific authority of a transcendental value of truth was a view held almost universally by the greatest scientists throughout recorded history, modern science has all-but banished references to truth from professional scientific discourse - these being regarded as wishful, mystical and embarrassing at best, and hypocritical or manipulative at worst. With truth excluded, the highest remaining evaluation mechanism is 'professional consensus' or peer review - beyond which there is no higher court of appeal. Yet in Human accomplishment, Murray argues that cultures which foster great achievement need transcendental values (truth, beauty and virtue) to be a live presence in the culture; such that great artists and thinkers compete to come closer to the ideal. So a scientific system including truth as a live presence apparently performs better than a system which excludes truth. Transcendental truth therefore seems to be real in the pragmatic sense that it makes a difference. To restore the primacy of truth to science a necessary step would be to ensure that only truth-seekers were recruited to the key scientific positions, and to exclude from leadership those who are untruthful or exhibit insufficient devotion to the pursuit of truth. In sum, to remain anchored in its proper role, science should through 'truth talk' frequently be referencing normal professional practice to transcendental truth values. Ultimately, science should be conducted at every level, from top to bottom, on the basis of what Bronowski termed the 'habit of truth'. Such a situation currently

    The American Legacy Foundation developed the truth campaign, an aspirational antismoking brand for adolescents. This study tested whether a multidimensional scale, brand equity in truth, mediates the relationship between campaign exposure and youth smoking. We collected brand equity responses from 2,306 youth on a nationally representative telephone survey. Factor analysis indicates that the scale has excellent psychometric properties and effectively measures brand equity. We developed a structural equation model to test the mediation hypothesis. Results show that brand equity mediates the relationship between truth and smoking. Analyses of potential cofounders show this relationship is robust. Behavioral branding (brands about a behavior or a lifestyle) is an important public health strategy.

    Over the past few years several automatic and semi-automatic PET segmentation methods for target volume definition in radiotherapy have been proposed. The objective of this study is to compare different methods in terms of dosimetry. For such a comparison, a gold standard is needed. For this purpose, realistic GATE-simulated PET images were used. Three lung cases and three H and N cases were designed with various shapes, contrasts and heterogeneities. Four different segmentation approaches were compared: fixed and adaptive thresholds, a fuzzy C-mean and the fuzzy locally adaptive Bayesian method. For each of these target volumes, an IMRT treatment plan was defined. The different algorithms and resulting plans were compared in terms of segmentation errors and ground-truth volume coverage using different metrics (V 95 , D 95 , homogeneity index and conformity index). The major differences between the threshold-based methods and automatic methods occurred in the most heterogeneous cases. Within the two groups, the major differences occurred for low contrast cases. For homogeneous cases, equivalent ground-truth volume coverage was observed for all methods but for more heterogeneous cases, significantly lower coverage was observed for threshold-based methods. Our study demonstrates that significant dosimetry errors can be avoided by using more advanced image-segmentation methods. (paper)

    Owing to ICT-enabled citizen observatories, citizens can take on new roles in environmental monitoring, decision making and co-operative planning, and environmental stewardship. And yet implementing advanced citizen observatories for data collection, knowledge exchange and interactions to support policy objectives is neither always easy nor successful, given the required commitment, trust, and data reliability concerns. Many efforts are facing problems with the uptake and sustained engagement by citizens, limited scalability, unclear long-term sustainability and limited actual impact on governance processes. Similarly, to sustain the engagement of decision makers in citizen observatories, mechanisms are required from the start of the initiative in order to have them invest in and, hence, commit to and own the entire process. In order to implement sustainable citizen observatories, these social dimensions therefore need to be soundly managed. We provide empirical evidence of how the social dimensions of citizen observatories are being addressed in the Ground Truth 2.0 project, drawing on a range of relevant social science approaches. This project combines the social dimensions of citizen observatories with enabling technologies - via a socio-technical approach - so that their customisation and deployment is tailored to the envisaged societal and economic impacts of the observatories. The projects consists of the demonstration and validation of six scaled up citizen observatories in real operational conditions both in the EU and in Africa, with a specific focus on flora and fauna as well as water availability and water quality for land and natural resources management. The demonstration cases (4 EU and 2 African) cover the full 'spectrum' of citizen-sensed data usage and citizen engagement, and therefore allow testing and validation of the socio-technical concept for citizen observatories under a range of conditions.

    Deceptive practice has been shown to be endemic in long-term care settings. However, little is known about the use of deception in dementia care within general hospitals and staff attitudes towards this practice. This study aimed to develop understanding of the experiences of general hospital staff and explore their decision-making processes when choosing whether to tell the truth or deceive a patient with dementia. This qualitative study drew upon a constructivist grounded theory approach to analyse data gathered from semi-structured interviews with a range of hospital staff. A model, grounded in participant experiences, was developed to describe their decision-making processes. Participants identified particular triggers that set in motion the need for a response. Various mediating factors influenced how staff chose to respond to these triggers. Overall, hospital staff were reluctant to either tell the truth or to lie to patients. Instead, 'distracting' or 'passing the buck' to another member of staff were preferred strategies. The issue of how truth and deception are defined was identified. The study adds to the growing research regarding the use of lies in dementia care by considering the decision-making processes for staff in general hospitals. Various factors influence how staff choose to respond to patients with dementia and whether deception is used. Similarities and differences with long-term dementia care settings are discussed. Clinical and research implications include: opening up the topic for further debate, implementing staff training about communication and evaluating the impact of these processes.

  7. Japanese attitudes towards truth disclosure in cancer.

    Science.gov (United States)

    Tanida, N

    1994-03-01

    Despite the increasing concerns of truth disclosure, most cancer patients are not told the truth about their disease in Japan. The author has tried to provide some insight into this issue by evaluating results from questionnaires given to hospital patients, clients in a mass cancer survey, and doctors of a college hospital. Results showed that 72% of patients and 83% of clients wanted to be told the truth, but only 33% and 34% of them thought that the truth should be told to cancer patients. These attitudes of patients and clients regarding truth disclosure were more positive than those of the general public and health care workers in previous studies. At present, 13% of doctors inform cancer patients of their disease. These trends indicate that the Japanese attitude toward avoiding truth disclosure stems primarily from paternalism but is also influenced by social characteristics including insufficient understanding of this issue. Open discussion involving all factions of society is necessary to attain a better understanding of this issue and to promote eventual truth disclosure.

    We present the nitrogen isotope ratios (δ15N) of planktonic foraminifera, a type of calcifying zooplankton, collected from surface ocean net tows, moored sediment traps and core-top sediments at the Bermuda Atlantic Time-series Study site in the Sargasso Sea between 2009 and 2013. Consistent with previous measurements from low-latitude core-top sediments, the annually averaged δ15N of organic matter bound within the shells of euphotic zone-dwelling foraminifera approximates that of thermocline nitrate, the dominant source of new nitrogen to Sargasso Sea surface waters. Based on net tow collections in the upper 200 m of the water column, we observe no systematic difference between the biomass δ15N and shell-bound δ15N of a given foraminifera species. For multiple species, the δ15N of net tow-collected upper ocean shells is lower than shells from sediment traps (by 0.5-2.1‰) and lower than shells from seafloor sediments (by 0.5-1.4‰). We are currently investigating whether these differences reflect actual processes affecting shell-bound δ15N or instead relate to the different time periods over which the three sample types integrate. The foraminiferal biomass δ15N time-series from the surface Sargasso Sea exhibits significant seasonal variations, with the lowest values in fall and the highest values in spring. The roles of hydrography, biogeochemistry, and ecosystem dynamics in driving these seasonal variations will be discussed. These data from the modern subtropical ocean form part of a greater effort to ground-truth the use of foram-bound δ15N to reconstruct past nutrient conditions, not only as a recorder of the isotopic composition of nitrogen supply in oligotrophic environments but also as a recorder of the degree of nitrate consumption in high-latitude regions such as the Southern Ocean.

    International Nuclear Information System (INIS)

    Chamness, M.A.; Luttrell, S.P.; Dudziak, S.

    1989-03-01

    This report outlines a ground-water monitoring plan for the 2101-M pond, located in the southwestern part of the 200-East Area on the Hanford Site in south-central Washington State. It has been determined that hazardous materials may have been discharged to the pond. Installation of an interim-status ground-water monitoring system is required under the Resource Conservation and Recovery Act to determine if hazardous chemicals are moving out of the pond. This plan describes the location of new wells for the monitoring system, how the wells are to be completed, the data to be collected, and how those data can be used to determine the source and extent of any ground-water contamination from the 2101-M pond. Four new wells are planned, one upgradient and three downgradient. 35 refs., 12 figs., 9 tabs

    Full Text Available The subject of our study was the concept of "truth" in Bulgakov's novel Master and Margarita. S. Stepanov gave the defi nition of a concept. The concept is like a clot of culture in human consciousness; that is the manner, in which culture becomes a part of the mental world of a man. And, on the other hand, the concept is a way for a man as an ordinary, normal person, not a "creator of cultural values" to be included in the culture, and in some cases, to affects it. In the analysis of the concept of "truth" we start from its cultural-and-etymological understanding of the word "truth". The aim of the study was to conduct a comparative analysis of the three editions of the novel and to fi nd out what semantic meanings Bulgakov deals with in a particular case and how it aff ects the transformation of the idea of the novel from edition to edition.Three editions of the novel were the material for the research: the first is "Engineer Hoof " (1930–1932, the second is Grand Chancellor (1932–1934 and the fi nal version of "The Master and Margarita." In these three editions Yeshua involves everyone who he is talking to in the dialogue. In the editions Engineer Hoof and Grand Chancellor M. A. Bulgakov uses the concept of "truth" in scientific- philosophical and sacred meanings (plans. In the final text Yeshua appears as a philosopher who is in search of the truth.

    A ground system is described which is compatible with the operational requirements of the space telescope. The goal of the ground system is to minimize the cost of post launch operations without seriously compromising the quality and total throughput of space telescope science, or jeopardizing the safety of the space telescope in orbit. The resulting system is able to accomplish this goal through optimum use of existing and planned resources and institutional facilities. Cost is also reduced and efficiency in operation increased by drawing on existing experience in interfacing guest astronomers with spacecraft as well as mission control experience obtained in the operation of present astronomical spacecraft.

  17. Learning from nuclear waste repository design: the ground-control plan

    International Nuclear Information System (INIS)

    1988-01-01

    At present, under a U.S. Department of Energy program, three repositories for commercial spent fuel-in salt, tuff and basalt-are in the phase of site characterization and conceptual design, and one pilot project for defense waste in salt is under development. Because of strict quality assurance requirements throughout design and construction, and the need to predict and ascertain in advance the satisfactory performance of the underground openings, underground openings in the unusual circumstances of the repository environment have been analysed. This will lead to an improved understanding of rock behavior and improved methods of underground analysis and design. A formalized ground control plan was developed, the principles of which may be applied to other types of projects. This paper summarizes the status of underground design and construction for nuclear waste repositories and presents some details of the ground control plan and its individual elements. (author)

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available For societies suffering in the wake of a repressive regime, truth commissions may be a necessary compromise regarding the form of transitional justice pursued, but they can still play a far-reaching role in the democratization of civil-military relations. Because the perpetrators of past abuses are likely to continue to wield some level of power at the time of transition, prosecution of these members may be politically infeasible. Lacking the mandate to prosecute guilty parties or implement recommendations, truth commissions can still lay the foundation for a new era of civil-military relations. By distinguishing contemporary institutions from their past acts, revealing the patterns that allowed abuses to be carried out , and helping garner the political will for reforms, truth commissions can provide the impetus for the security sector reforms necessary to ensure a democratic future.

  19. A Bayesian truth serum for subjective data.

    2004-10-15

    Subjective judgments, an essential information source for science and policy, are problematic because there are no public criteria for assessing judgmental truthfulness. I present a scoring method for eliciting truthful subjective data in situations where objective truth is unknowable. The method assigns high scores not to the most common answers but to the answers that are more common than collectively predicted, with predictions drawn from the same population. This simple adjustment in the scoring criterion removes all bias in favor of consensus: Truthful answers maximize expected score even for respondents who believe that their answer represents a minority view.

    The usual way of interpreting Goedel's (1931) incompleteness result is as showing that there is a gap between truth and provability, i.e. that we can never prove everything that is true. Moreover, this result is supposed to show that there are unprovable truths which we can know to be true. This, so the story goes, shows that we are more than machines that are restricted to acting as proof systems. Hence our minds are 'not mechanical'

    This report describes two complementary approaches to the problem of space mission planning and scheduling. The first is an Expert System or Knowledge-Based System for automatically resolving most of the activity conflicts in a candidate plan. The second is an Interactive Graphics Decision Aid to assist the operator in manually resolving the residual conflicts which are beyond the scope of the Expert System. The two system designs are consistent with future ground control station activity requirements, support activity timing constraints, resource limits and activity priority guidelines.

  2. The Effect of Telling Lies on Belief in the Truth

    Directory of Open Access Journals (Sweden)

    Danielle Polage

    2017-11-01

    Full Text Available The current study looks at the effect of telling lies, in contrast to simply planning lies, on participants’ belief in the truth. Participants planned and told a lie, planned to tell a lie but didn’t tell it, told an unplanned lie, or neither planned nor told a lie (control about events that did not actually happen to them. Participants attempted to convince researchers that all of the stories told were true. Results show that telling a lie plays a more important role in inflating belief scores than simply preparing the script of a lie. Cognitive dissonance may lead to motivated forgetting of information that does not align with the lie. This research suggests that telling lies may lead to confusion as to the veracity of the lie leading to inflated belief scores.

    Highlights: • New recommendations for NPP planning were addressed taking into account collapse-induced ground vibration. • Critical factors influencing the collapse-induced ground vibration were investigated. • Comprehensive approach was presented to describe the initiation and propagation of collapse-induced disaster. - Abstract: Ground vibration induced by collapse of large-scale cooling towers can detrimentally influence the safe operation of adjacent nuclear-related facilities. To prevent and mitigate these hazards, new planning methods for nuclear power plants (NPPs) were studied considering the influence of these hazards. First, a “cooling tower-soil” model was developed, verified, and used as a numerical means to investigate ground vibration. Afterwards, five critical factors influencing collapse-induced ground vibration were analyzed in-depth. These influencing factors included the height and weight of the towers, accidental loads, soil properties, overlying soil, and isolation trench. Finally, recommendations relating to the control and mitigation of collapse-induced ground vibration in NPP planning were proposed, which addressed five issues, i.e., appropriate spacing between a cooling tower and the nuclear island, control of collapse modes, sitting of a cooling tower and the nuclear island, application of vibration reduction techniques, and the influence of tower collapse on surroundings.

  6. [Medicine and truth: between science and narrative].

    Science.gov (United States)

    Materia, Enrico; Baglio, Giovanni

    2009-01-01

    To which idea of truth may medicine refer? Evidence-based medicine (EBM) is rooted in the scientific truth. To explain the meaning and to trace the evolution of scientific truth, this article outlines the history of the Scientific Revolution and of the parable of Modernity, up to the arrival of pragmatism and hermeneutics. Here, the concept of truth becomes somehow discomfiting and the momentum leans towards the integration of different points of view. The fuzzy set theory for the definition of disease, as well as the shift from disease to syndrome (which has operational relevance for geriatrics), seems to refer to a more complex perspective on knowledge, albeit one that is less defined as compared to the nosology in use. Supporters of narrative medicine seek the truth in the interpretation of the patients' stories, and take advantage of the medical humanities to find the truth in words, feelings and contact with the patients. Hence, it is possible to mention the parresia, which is the frank communication espoused by stoicism and epicureanism, a technical and ethical quality which allows one to care in the proper way, a true discourse for one's own moral stance. Meanwhile, EBM and narrative medicine are converging towards a point at which medicine is considered a practical knowledge. It is the perspective of complexity that as a zeitgeist explains these multiple instances and proposes multiplicity and uncertainty as key referents for the truth and the practice of medicine.

    1988-09-01

    This document contains ground-water monitoring plans for process-water disposal trenches located on the Hanford Site. These trenches, designated the 300 Area Process Trenches, have been used since 1973 for disposal of water that contains small quantities of both chemicals and radionuclides. The ground-water monitoring plans contained herein represent revision and expansion of an effort initiated in June 1985. At that time, a facility-specific monitoring program was implemented at the 300 Area Process Trenches as part of a regulatory compliance effort for hazardous chemicals being conducted on the Hanford Site. This monitoring program was based on the ground-water monitoring requirements for interim-status facilities, which are those facilities that do not yet have final permits, but are authorized to continue interim operations while engaged in the permitting process. The applicable monitoring requirements are described in the Resource Conservation and Recovery Act (RCRA), 40 CFR 265.90 of the federal regulations, and in WAC 173-303-400 of Washington State's regulations (Washington State Department of Ecology 1986). The program implemented for the process trenches was designed to be an alternate program, which is required instead of the standard detection program when a facility is known or suspected to have contaminated the ground water in the uppermost aquifer. The plans for the program, contained in a document prepared by the US Department of Energy (USDOE) in 1985, called for monthly sampling of 14 of the 37 existing monitoring wells at the 300 Area plus the installation and sampling of 2 new wells. 27 refs., 25 figs., 15 tabs.

    This essay takes up a series of questions about the connection between 'symmetry' in Science and Technology Studies (STS) and 'post-truth' in contemporary politics. A recent editorial in this journal by Sergio Sismondo argues that current discussions of 'post-truth' have little to do with conceptions of 'symmetry' or with concerns about 'epistemic democracy' in STS, while others, such as Steve Fuller and Harry Collins, insist that there are such connections. The present essay discusses a series of questions about the meaning of 'post-truth' and 'symmetry', and the connections of those concepts to each other and to 'epistemic democracy'. The essay ends with a series of other questions about STS and contemporary politics, and an invitation to further discussions.

    At the Kennedy Space Center (KSC) in Florida, processing facilities are being built and activated to support the processing, checkout, and launch of Space Station elements. The generic capability of these facilities will be utilized to support resupply missions for payloads, life support services, and propellants for the 30-year life of the program. Special Ground Support Equipment (GSE) is being designed for Space Station hardware special handling requirements, and a Test, Checkout, and Monitoring System (TCMS) is under development to verify that the flight elements are ready for launch. The facilities and equipment used at KSC, along with the testing required to accomplish the mission, are described in detail to provide an understanding of the complexity of operations at the launch site. Assessments of hardware processing flows through KSC are being conducted to minimize the processing flow times for each hardware element. Baseline operations plans and the changes made to improve operations and reduce costs are described, recognizing that efficient ground operations are a major key to success of the Space Station.

  10. Truth, not truce: "common ground" on abortion, a movement within both movements.

    Science.gov (United States)

    Kelly, J R

    1995-01-01

    This sociological study examines the "common ground" movement that arose among abortion activists in the US during the 1980s. The first application of the term "common ground" to joint efforts by abortion activists on both sides of the issue is traced, and its meaning to early organizers is described. Discussion continues on the complicated and elusive efforts on the part of grassroots organizations and conflict resolution groups to practice the common ground approach to abortion. The five characteristics of the seminal common ground group in St. Louis were that it resulted from a combined pro-life and pro-choice initiative, it involved activists who publicly distinguished common ground from moral compromise or political accommodation, the activists remained loyal to their abortion activities, the activists agreed to cooperate in efforts aimed at reducing the pressures on women to abort, and common ground involved identifying the overlaps in emerging social thinking. The conceptual difficulties involved with use of the term are included in the reasons given for its virtual disappearance from abortion reporting in the press, which was busy relaying incidents of violence at abortion clinics. The election of President Clinton also stole the momentum from the common ground movement. While the future of movements based on the concept of "common ground" as envisioned by the St. Louis group remains precarious, depending for success as it does on actually changing society, this use of the term bears witness that conflicting loyalties do not preclude the promotion of common good. This meaning of the term is worth pursuing in cultural controversies such as that posed by abortion.

This facility has been used since 1973 for storage of mixed wastes, which contain both chemicals and radionuclides. The ground-water monitoring plans presented here represent revision and expansion of an effort in June 1985. At that time, a facility-specific monitoring program was implemented at the 183-H Basins as part of the regulatory compliance effort being conducted on the Hanford Site. This monitoring program was based on the ground-water monitoring requirements for interimstatus facilities, which are those facilities that do not yet have final permits, but are authorized to continue interim operations while engaged in the permitting process. The program initially implemented for the 183-H Basins was designed to be an alternate program, which is required instead of the standard detection program when a facility is known or suspected to have contaminated the ground water in the uppermost aquifer. This effort, named the RCRA Compliance Ground-Water Monitoring Project for the 183-H Basins, was implemented. A supporting project involving ground-water flow modeling for the area surrounding the 183-H Basins was also initiated during 1985. Those efforts and the results obtained are described in subsequent chapters of this document. 26 refs., 55 figs., 14 tabs

    2008-05-15

    This article discussed the use of kite aerial photography (KAP) in oil and gas exploration activities. KAP exhibits a minimal environmental footprint while providing high resolution airborne data of the Earth's surface in infrared and a variety of other media. The cost-effective technology is being employed by Alberta's oil and gas operators as well as by the environmental consulting sector. The kites fly at lower elevations than other remote sensing tools, and yield better spatial resolution on the ground. KAP can map the Earth's surface at a scale of investigation on the order of 5 to 10 centimetres. The images are placed into a geo-referenced mosaic along with poorer resolution remote sensing tools. A KAP kit can be assembled for under $1000. By using infrared KAP images, operators are able to determine the health of muskeg and swamp areas and measure the rate of photosynthesis of plants. KAP is also used to evaluate troublesome wellsite by reclamation groups. The next generation of sensors will include radio-controlled drones and miniature aircraft. 6 figs.

In a religious context ‘truth’ is like a mantra, a certain imperative to believe in sacred things. The concept of truth and falseness arises, when we as humans compare reality, as we experience it through our senses, with the representation we have in our memory, a comparison of new information with stored information. If we look for the truth, we have to search in the human mind. There we will also find religion.

    1989-03-01

    This document outlines a ground-water monitoring plan for the 216-B-63 trench located in the northeast corner of the 200-East Area on the Hanford Site in southeastern Washington State. It has been determined that hazardous materials (corrosives) were disposed of to the trench during past operations. Installation of an interim-status ground-water monitoring system is required to determine whether hazardous chemicals are leaching to the ground water from beneath the trench. This document summarizes the existing data that are available from near the 216-B-63 trench and presents a plan to determine the extent of ground-water contamination, if any, derived from the trench. The plan calls for the installation of four new monitoring wells located near the west end of the trench. These wells will be used to monitor ground-water levels and water quality immediately adjacent to the trench. Two existing RCRA monitoring wells, which are located near the trench and hydraulically upgradient of it, will be used as background wells. 46 refs., 15 figs., 12 tabs

The main objective is to estimate maximum and minimum Ta (Ta-max and Ta-min using both TERRA and AQUA MODIS LST products (daytime and nighttime and auxiliary data, solving the discontinuity problem of ground measurements. There exist no studies about Vietnam that have integrated both TERRA and AQUA LST of daytime and nighttime for Ta estimation (using four MODIS LST datasets. In addition, to find out which variables are the most effective to describe the differences between LST and Ta, we have tested several popular methods, such as: the Pearson correlation coefficient, stepwise, Bayesian information criterion (BIC, adjusted R-squared and the principal component analysis (PCA of 14 variables (including: LST products (four variables, NDVI, elevation, latitude, longitude, day length in hours, Julian day and four variables of the view zenith angle, and then, we applied nine models for Ta-max estimation and nine models for Ta-min estimation. The results showed that the differences between MODIS LST and ground truth temperature derived from 15 climate stations are time and regional topography dependent. The best results for Ta-max and Ta-min estimation were achieved when we combined both LST daytime and nighttime of TERRA and AQUA and data from the topography analysis.

    1990-01-01

    Receiver operator characteristic (ROC) analysis, the preferred method of evaluating diagnostic imaging tests, requires an independent assessment of the true state of disease, which can be difficult to obtain and is often of questionable accuracy. A new method of analysis is described which does not require independent truth data and which can be used when several accurate tests are being compared. This method uses correlative information to estimate the underlying model of multivariate normal distributions of disease-positive and disease-negative patients. The method is shown to give results equivalent to conventional ROC analysis in a comparison of computed tomography, radionuclide scintigraphy, and magnetic resonance imaging for liver metastasis. When independent truth is available, the method can be extended to incorporate truth data or to evaluate the consistency of the truth data with the imaging data

  5. Park Planning for Ageing Adults Using Grounded Theory Methodology

    2004-06-01

    Full Text Available The importance of understanding park planning issues and implementing planning strategies for ageing adults was the driving force for this study. Literature reviews have identified a variety of scholarly work from fields such as gerontology, psychology, sociology and economics, all of which provide valuable information regarding the special needs of ageing adults. Very few researchers, however, have investigated the leisure behaviours of older adults in outdoor recreation (Croskeys, Tinsley and Tinsley, 2002 and the use of grounded theory methodology has essentially been unexplored in this area. Ageing adults are projected to live more than 20 percent of their life in retirement (MRP, 1998, cited in Croskeys, Tinsley and Tinsley, 2002, allowing for an increased amount of discretionary time. This offers opportunities for ageing adults to participate in outdoor recreational activities and will undoubtedly increase their leisure time. However, with limited research in recreational needs and inclusion for older adults, it is difficult for park planners and administrators to meet the growing needs of this population. Therefore, this research is necessary in order to determine whether ageing adults are being accounted for in park and outdoor recreational planning. The objective of this study was to use grounded theory research methodology to identify and examine ageing adult needs in relation to outdoor leisure activities in a regional park setting. Ten Midwestern regional park visitors (aged 65-75 years old and four park employees were interviewed. Our research attempts to fill in the gaps between the perceptions of ageing park users and those of park planners, using a methodology that relies primarily on direct contact with park visitors.

    The paper describes an LST ground system which is compatible with the operational requirements of the LST. The goal of the approach is to minimize the cost of post launch operations without seriously compromising the quality and total throughput of LST science. Attention is given to cost constraints and guidelines, the telemetry operations processing systems (TELOPS), the image processing facility, ground system planning and data flow, and scientific interfaces.

  7. HOW TRUTHFUL ARE WATER ACCOUNTING DATA?

    Full Text Available Water accounting is an important tool for water managers. Many studies use official water accounting data or similar data for their assessment. In particular, large-scale studies or water footprint studies have limited opportunities for “in-situ” data collection. In many cases, the processors of studies do not know the origin of the data and their limitations. Water accounting data are very often used for decision-making process, water resource management, and planning in the water sector. This article tries to answer the question “How truthful are water accounting data?” For this task water accounting in the agriculture sector in the Czech Republic was selected. The data on water withdrawals for the agriculture purposes was analysed and compared with water needs estimation based on additional data on agricultural production.

  9. La verità scientifica - Scientific truth

    Directory of Open Access Journals (Sweden)

    Marco Mazzeo

    2012-10-01

    Full Text Available A scientific theory is not a speculation. On the contrary it is based on facts and observations. Nevertheless the facts and the observations are unable to show us the truth about the world. Indeed to understand the facts or even to discover them through experiments we need a starting theory about the world. Therefore the world is not only discovered by us, but we can say that it is created by our brain. Facts are the constraints for the possible theories and theories are creations of our minds to understand the facts. There are no facts without a theory in mind, and there are no scientific theories about the world without facts. It is obvious therefore that science cannot give any absolute truth but “only” temporary truths which will change with new discoveries and theories. The scientific truth is therefore unstable: after few decades the concepts become unable to explain the news discoveries and become old, but the new concepts will include the old ones. This is called science progress. In this work we analyze all these points discussing the historical creation of the gravitational theory from Aristotle to Newton.

    Masuda, Naoki; Redner, S.

    2011-02-01

    We study an extension of the voter model in which each agent is endowed with an innate preference for one of two states that we term as 'truth' or 'falsehood'. Due to interactions with neighbors, an agent that innately prefers truth can be persuaded to adopt a false opinion (and thus be discordant with its innate preference) or the agent can possess an internally concordant 'true' opinion. Parallel states exist for agents that inherently prefer falsehood. We determine the conditions under which a population of such agents can ultimately reach a consensus for the truth, reach a consensus for falsehood, or reach an impasse where an agent tends to adopt the opinion that is in internal concordance with its innate preference with the outcome that consensus is never achieved.

    The attitudes of scientists towards the philosophy of science is mixed and includes considerable indifference and some hostility. This may be due in part to unrealistic expectation and to misunderstanding. Philosophy is unlikely directly to improve scientific practices, but scientists may find the attempt to explain how science works and what it achieves of considerable interest nevertheless. The present state of the philosophy of science is illustrated by recent work on the 'truth hypothesis', according to which, science is generating increasingly accurate representations of a mind-independent and largely unobservable world. According to Karl Popper, although truth is the aim of science, it is impossible to justify the truth hypothesis. According to Thomas Kuhn, the truth hypothesis is false, because scientists can only describe a world that is partially constituted by their own theories and hence not mind-independent. The failure of past scientific theories has been used to argue against the truth hypothesis; the success of the best current theories has been used to argue for it. Neither argument is sound.

  13. On authenticity: the question of truth in construction and autobiography.

    Science.gov (United States)

    Collins, Sara

    2011-12-01

    Freud was occupied with the question of truth and its verification throughout his work. He looked to archaeology for an evidence model to support his ideas on reconstruction. He also referred to literature regarding truth in reconstruction, where he saw shifts between historical fact and invention, and detected such swings in his own case histories. In his late work Freud pondered over the impossibility of truth in reconstruction by juxtaposing truth with 'probability'. Developments on the role of fantasy and myth in reconstruction and contemporary debates over objectivity have increasingly highlighted the question of 'truth' in psychoanalysis. I will argue that 'authenticity' is a helpful concept in furthering the discussion over truth in reconstruction. Authenticity denotes that which is genuine, trustworthy and emotionally accurate in a reconstruction, as observed within the immediacy of the analyst/patient interaction. As authenticity signifies genuineness in a contemporary context its origins are verifiable through the analyst's own observations of the analytic process itself. Therefore, authenticity is about the likelihood and approximation of historical truth rather than its certainty. In that respect it links with Freud's musings over 'probability'. Developments on writing 'truths' in autobiography mirror those in reconstruction, and lend corroborative support from another source. Copyright © 2011 Institute of Psychoanalysis.

  14. An inconvenient truth

    2007-01-01

    Our climate crisis may at times appear to be happening slowly, but in fact it is happening very quickly-and has become a true planetary emergency. The Chinese expression for crisis consists of two characters. The first is a symbol for danger; the second is a symbol for opportunity. In order to face down the danger that is stalking us and move through it, we first have to recognize that we are facing a crisis. So why is it that our leaders seem not to hear such clarion warnings? Are they resisting the truth because they know that the moment they acknowledge it, they will face a moral imperative to act? Is it simply more convenient to ignore the warnings? Perhaps, but inconvenient truths do not go away just because they are not seen. Indeed, when they are responded to, their significance does not diminish; it grows. (author)

  16. Generation of Ground Truth Datasets for the Analysis of 3d Point Clouds in Urban Scenes Acquired via Different Sensors

    Science.gov (United States)

    Xu, Y.; Sun, Z.; Boerner, R.; Koch, T.; Hoegner, L.; Stilla, U.

    2018-04-01

    In this work, we report a novel way of generating ground truth dataset for analyzing point cloud from different sensors and the validation of algorithms. Instead of directly labeling large amount of 3D points requiring time consuming manual work, a multi-resolution 3D voxel grid for the testing site is generated. Then, with the help of a set of basic labeled points from the reference dataset, we can generate a 3D labeled space of the entire testing site with different resolutions. Specifically, an octree-based voxel structure is applied to voxelize the annotated reference point cloud, by which all the points are organized by 3D grids of multi-resolutions. When automatically annotating the new testing point clouds, a voting based approach is adopted to the labeled points within multiple resolution voxels, in order to assign a semantic label to the 3D space represented by the voxel. Lastly, robust line- and plane-based fast registration methods are developed for aligning point clouds obtained via various sensors. Benefiting from the labeled 3D spatial information, we can easily create new annotated 3D point clouds of different sensors of the same scene directly by considering the corresponding labels of 3D space the points located, which would be convenient for the validation and evaluation of algorithms related to point cloud interpretation and semantic segmentation.

    .7%. Temperature and relative humidity sensors were placed in the playa at 5, 20, and 30 cm below the surface. Since the relative humidity neared 100% (down to 20 cm below the surface), high enough to support microbial life, the observed absence of methane production in the playa itself is likely due to the low POC content, compared to other methane-producing environments. The spatial distribution of methane in combination with the spectral reflectance at the RRV dry lakebed makes it a good Mars analog. The ground truthing and satellite calibration work accomplished at RRV is a good exercise in preparation to identifying the origins of methane observed in the atmosphere of Mars during the upcoming 2012 Mars Science Laboratory and 2016 ExoMars Trace Gas Orbiter missions.

  1. On a Philosophical Motivation for Mutilating Truth Tables

    Directory of Open Access Journals (Sweden)

    Marcos Silva

    2016-06-01

    Full Text Available One of the reasons colours, or better the conceptual organisation of the colour system, could be relevant to the philosophy of logic is that they necessitate some mutilation of truth tables by restricting truth functionality. This paper argues that the so-called ‘Colour Exclusion Problem’, the first great challenge for Wittgenstein’s Tractatus, is a legitimate philosophical motivation for a systematic mutilation of truth tables. It shows how one can express, through these mutilations, some intensional logical relations usually expressed by the Aristotelian Square of Oppositions, as contrariety and subcontrariety.

  2. CRITERIA OF TRUTHFULNESS AND THE SCIENTIFIC QUALITY IN POST-MODERN KNOWLEDGE

    Directory of Open Access Journals (Sweden)

    Olga Mukha

    2012-02-01

    Full Text Available This article examines the criteria of truth in post-modern philosophy, taking into account the ways it is defined in both the classical and non-classical traditions. Specific to post-modern philosophy is the absence of a universal language of narration and the traditional methods in which knowledge is recognized as legitimate. Basing himself on these concepts, the author examines the problem of the ideal of scientific quality and the transformations this idea has undergone in contemporary philosophy. Truth is understood basically through two means which govern our relation to truth: the will to truth and the concern for truth. These also appear as defining factors of truth in various types of post-modern philosophy: social-operative, social-political, and aesthetic

  3. Truth and opinion in climate change discourse: the Gore-Hansen disagreement.

    Russill, Chris

    2011-11-01

    In this paper, I discuss the "inconvenient truth" strategy of Al Gore. I argue that Gore's notion of truth upholds a conception of science and policy that narrows our understanding of climate change discourse. In one notable exchange, Gore and NASA scientist, James Hansen, disagreed about whether scientific statements based on Hansen's computer simulations were truth or opinion. This exchange is featured in An Inconvenient Truth, yet the disagreement is edited from the film and presented simply as an instance of Hansen speaking "inconvenient truth". In this article, I compare the filmic representation of Hansen's testimony with the congressional record. I place their exchange in a broader historical perspective on climate change disputation in order to discuss the implications of Gore's perspective on truth.

  4. DID RAMSEY EVER ENDORSE A REDUNDANCY THEORY OF TRUTH?

    Directory of Open Access Journals (Sweden)

    María J. Frápolli

    2013-11-01

    Full Text Available This paper deals with Ramsey´s theory of truth and its aim is twofold: on the one hand, it will explain what position about truth Ramsey actually defended, and, on the other hand, we will pursue Ramsey’s insight in the XXth century. When the name of Frank Ramsey is mentioned, one of the things that comes to mind is the theory of truth as redundancy. In the following pages we will argue that Ramsey never supported such a theory, but rather an analysis of truth noticeably similar to the prosentential account. In fact, the very word “pro-sentence” appears for the first time in the XXth Century in Ramsey´s unfinished work “The nature of truth”, written around 1929. Besides, we will show that the prosentential account of truth is a neglected trend throughout the history of analytic philosophy, even though relevant analytic philosophers, such as Prior, Strawson, Williams, Grover and Brandom, have endorsed it.

    2011-04-01

    Full Text Available This article proposes a theoretically approach over the relations that journalism establishes with the concept of truth. The notion of truth in Foucault leads the debate. This reflection centers on how journalism builds discursive strategies that produces effects of truth on itsreports. The journalist discourse presents itselfas truthful, although its constructive discourse of the world is a result of rules, practices and values. The debate of “truth” allows us to comprehend the complexity and particularities of journalism as a discursive practice that has reflection in the social knowledge of reality.

  7. Realism without truth: a review of Giere's science without laws and scientific perspectivism.

    Science.gov (United States)

    Hackenberg, Timothy D

    2009-05-01

    An increasingly popular view among philosophers of science is that of science as action-as the collective activity of scientists working in socially-coordinated communities. Scientists are seen not as dispassionate pursuers of Truth, but as active participants in a social enterprise, and science is viewed on a continuum with other human activities. When taken to an extreme, the science-as-social-process view can be taken to imply that science is no different from any other human activity, and therefore can make no privileged claims about its knowledge of the world. Such extreme views are normally contrasted with equally extreme views of classical science, as uncovering Universal Truth. In Science Without Laws and Scientific Perspectivism, Giere outlines an approach to understanding science that finds a middle ground between these extremes. He acknowledges that science occurs in a social and historical context, and that scientific models are constructions designed and created to serve human ends. At the same time, however, scientific models correspond to parts of the world in ways that can legitimately be termed objective. Giere's position, perspectival realism, shares important common ground with Skinner's writings on science, some of which are explored in this review. Perhaps most fundamentally, Giere shares with Skinner the view that science itself is amenable to scientific inquiry: scientific principles can and should be brought to bear on the process of science. The two approaches offer different but complementary perspectives on the nature of science, both of which are needed in a comprehensive understanding of science.

Since biblical truth was given to us “for the sake of our salvation,” and not in order to teach us natural science or history for their own sake, Sacred Scripture cannot be fairly judged to be in error when it sometimes presents historical or scientific truth in a less complete, less detailed, more popular, or more imprecise (i.e. merely approximate fashion than would be acceptable in modern texts dedicated formally to those disciplines.

  11. The Metaphysical Assumptions of the Conception of Truth in Martin Smiglecki’s Logic

    Directory of Open Access Journals (Sweden)

    Tomasz Pawlikowski

    2015-06-01

    Full Text Available The central element of the concept of truth in Smiglecki’s Logica (1618 is his approach to formulating definitions. Where the establishing of the truth is concerned, he always points to compliance at the level of the community (conformitas in respect of whether the intellectual recognition of a thing or things is in accordance with its intellectual equivalent, or the principles behind the latter, where these are understood as designating the corresponding idea inherent in the intellect of God. This is a form of the classical definition of truth --- similar to that used by St. Thomas Aquinas --- with a wide scope of applicability: to the field of existence (transcendental truth, to cognition and language (logical truth, and even to moral beliefs (moral rightness. Smiglecki distinguishes three types of truth: truth assigned to being, truth assigned to cognition, and truth assigned to moral convictions. Of these, the first is identified with transcendental truth, while the second is attributed not only to propositions and sentences, but also to concepts. The truth of concepts results from compliance with things by way of representation, while the truth of propositions and sentences issues from a compliance with things involving the implementation of some form of expression or other. Logical truth pertains to propositions rather than concepts. The kind of moral truth he writes about is what we would now be more likely to call “truthfulness”. With the exception of moral truth, which he defined as compliance of a statement with someone’s internal thoughts, Smiglecki considers every kind of truth to be a conditioned state of the object of knowledge. He says (a that the ultimate object of reference of human cognitive functioning is a real being, absolutely true by virtue of compliance with its internal principles and their idea as present in the intellect of God, and (b that the compatibility of human cognition with a real being is the ultimate

  13. Descartes on the Creation of the Eternal Truths

    Directory of Open Access Journals (Sweden)

    Danielle Macbeth

    2017-06-01

    Full Text Available On 15 April 1630, in a letter to Mersenne, Descartes announced that on his view God creates the truths of mathematics. Descartes returned to the theme in subsequent letters and some of his Replies but nowhere is the view systematically developed and defended. It is not clear why Descartes came to espouse the creation doctrine, nor even what exactly it is. Some have argued that his motivation was theological, that God creates the eternal truths, including the truths of logic, because and insofar as God is omnipotent andthe creator of all things. I develop and defend a different reading according to which Descartes was led to espouse the creation doctrine by a fundamental shift in his understanding of the correct mode of inquiry in metaphysics and mathematics: by 1630, the God-created truths came to play the role in inquiry that until then, in the Rules for the Direction of the Mind, had been played by images.

  14. The source of the truth bias: Heuristic processing?

    Science.gov (United States)

    Street, Chris N H; Masip, Jaume

    2015-06-01

    People believe others are telling the truth more often than they actually are; this is called the truth bias. Surprisingly, when a speaker is judged at multiple points across their statement the truth bias declines. Previous claims argue this is evidence of a shift from (biased) heuristic processing to (reasoned) analytical processing. In four experiments we contrast the heuristic-analytic model (HAM) with alternative accounts. In Experiment 1, the decrease in truth responding was not the result of speakers appearing more deceptive, but was instead attributable to the rater's processing style. Yet contrary to HAMs, across three experiments we found the decline in bias was not related to the amount of processing time available (Experiments 1-3) or the communication channel (Experiment 2). In Experiment 4 we found support for a new account: that the bias reflects whether raters perceive the statement to be internally consistent. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    1994-04-01

    Under the Uranium Mill Tailings Remedial Action (UMTRA) Project, the U.S. Department of Energy (DOE) is cleaning up contamination to protect human health and the environment at 24 inactive uranium processing sites located in 10 states. Five of the sites are either on or near Native American lands. The UMTRA Project is divided into two projects: Surface and Ground Water. On November 18, 1992, the DOE issued a notice of intent (57 FR 54374, 1992) to prepare a programmatic environmental impact statement (PEIS) for the UMTRA Ground Water Project. The PEIS will result in a record of decision that will determine how the UMTRA Ground Water Project will address ground water contamination resulting from milling operations at the UMTRA Project processing sites. DOE regulations (10 CFR section 1021.312) require that an implementation plan be prepared to provide guidance for preparing a PEIS and to record the results of the scoping process. This implementation plan describes and records the results of the PEIS scoping process; summarizes comments received and their disposition; describes the purpose of and need for agency action, the proposed action, and alternatives; lists alternatives considered and eliminated from review; identifies cooperating agencies, their roles, and responsibilities; provides a draft PEIS outline, which includes the planned PEIS scope and content (Attachment A); and provides a schedule for the PEIS process. This plan will be placed in the UMTRA Project libraries listed in Attachment B. The PEIS will identify and evaluate the potential impacts associated with alternatives for conducting the UMTRA Ground Water Project. The PEIS will not assess site-specific impacts; site-specific impacts must be analyzed in separate National Environmental Policy Act (NEPA) documents that will tier off the PEIS. This tiering process will streamline the preparation of site-specific NEPA documents

    Truth-telling is an important component of respect for patients' self-determination, but in the context of breaking bad news, it is also a distressing and difficult task. We investigated the long-term influence of a simulated patient-based teaching intervention, integrating learning objectives in communication skills and ethics into students' attitudes and concerns regarding truth-telling. We followed two cohorts of medical students from the preclinical third year to their clinical rotations (fifth year). Open-ended responses were analysed to explore medical students' reported difficulties in breaking bad news. This intervention was implemented during the last preclinical year of a problem-based medical curriculum, in collaboration between the doctor-patient communication and ethics programs. Over time, concerns such as empathy and truthfulness shifted from a personal to a relational focus. Whereas 'truthfulness' was a concern for the content of the message, 'truth-telling' included concerns on how information was communicated and how realistically it was received. Truth-telling required empathy, adaptation to the patient, and appropriate management of emotions, both for the patient's welfare and for a realistic understanding of the situation. Our study confirms that an intervention confronting students with a realistic situation succeeds in making them more aware of the real issues of truth-telling. Medical students deepened their reflection over time, acquiring a deeper understanding of the relational dimension of values such as truth-telling, and honing their view of empathy.

    A study of the way the media portrayed the Westray Mine disaster and its aftermath over the period 1992 to 2002 is presented. The chapters titles are; power, discourse, and the production of news as truth; the explosion and its aftermath; studying the press and Westray; the press and the presentation of Westray's truth; and the politics of truth and the invisibility of corporate crime. News articles reporting the accident and outcome were sampled, coded, and evaluated by content analysis. It is concluded that the various media represented alternative truths, but did not label the corporation as criminal. This was missing from the media's reporting of the disaster.

    Full Text Available It is required that the capital used for construction of road must be technical, economical and used in its location. For this reason, the projects must be prepared for forest roads and all operations belong to roads must be guided according to these projects. In this investigation, available forest road network plan and constructed forest roads were investigated at the point of view technical and forest transportation. After this, it were studied to reach the highest exploitation rate as can as possible. Available forest road density were found as 11.9 m/ha in forest areas for Yesiltepe District. In this condition, exploitation rate was 78 %. After that, optimum forest road network were planned and road density were reached to 22 m/ha and exploitation rate to 86 %. Directed sample method were used from taking soil sample methods and samples were took in mixed system. According to results of the experiments, available forest roads were found in a good degree at the point of view endurance, pressing and transportation capacity. With these results, it is aimed to reach higher exploitation rate with given attention to landslide areas during planning of forest roads on the mountain areas such as Black Sea Region. For this reason, required importance must be given to planning of truck and logging roads. Ground analysis must be done and took care before during planning process of forest road network.

    2014-05-01

    Full Text Available The case of autobiographical photo-texts is to be analyzed, first of all, as an autobiographical writing that feels the need to express by other means; secondly, as a specific rhetoric practice that chooses the image, next to the word, as a further persuasive force; finally, as a very special case of icono-texts, which uses some variety of the connection between the verbal and the visual. It is not only a matter of analyzing how it works the cooperation between photographs and autobiographical writing, that is, through which connectors – frames, white space, overlays and captions –, but also of understanding what are the functions of the photographs in relation to literature. This is in order to understand what truth is affirmed in the examples chosen: Franca Valeri, Grégoire Bouillier, Roland Barthes, Winfried G. Sebald, Lalla Romano, Jovanotti, Edward Said, Azar Nafisi, Vladimir Nabokov, André Breton, Hannah Höch, Annie Ernaux. Do photographs expose, confirm, add or resist the truth expressed by the literary side? And if narrative expresses the truth and the resistance to the truth of the author himself, what does the photo resist to, while showing?

    The original truth campaign was a branded, national smoking prevention mass media effort focused on at-risk youth ages 12-17. Today the truth brand focuses on the goal of finishing tobacco (truth FinishIt). There have been significant changes in the tobacco control landscape, leading FinishIt to focus on 15- to 21-year-olds. The present article reports on formative research and media monitoring data collected to pilot test a new truth FinishIt brand equity scale. The goals of this study were to (a) content analyze truth FinishIt mass media ads, (b) assess truth's social media and followers' perceptions of truth's digital brand identity, and (c) develop and feasibility test a new version of the truth FinishIt brand equity scale using data from an existing Truth Initiative media monitoring study. Through factor analysis, we identified a brand equity scale, as in previous research, consisting of 4 main constructs: brand loyalty, leadership/satisfaction, personality, and awareness. Targeted truth attitudes and beliefs about social perceptions, acceptability, and industry-related beliefs were regressed on the higher order factor and each of the 4 individual brand equity factors. Ordinary least squares regression models generally showed associations in the expected directions (positive for anti-tobacco and negative for pro-tobacco) between targeted attitudes/beliefs and truth FinishIt brand equity. This study succeeded in developing and validating a new truth FinishIt brand equity scale. The scale may be a valuable metric for future campaign evaluation. Future studies should examine the effects of truth FinishIt brand equity on tobacco use behavioral outcomes over time.

    Truth telling or transmitting bad news is a problem that all doctors must frequently face. The purpose of this cross-sectional study was to investigate if medical students' opinions of truth telling differed from their observations of attending physicians' actual clinical practice. The subjects were 275 medical clerks/interns at a medical center in northern Taiwan. Data were collected on medical students' opinions of truth telling, their observations of physicians' clinical practice, students' level of satisfaction with truth telling practiced by attending physicians, and cancer patients' distress level when they were told the truth. Students' truth-telling awareness was significantly higher than the clinical truth-telling practice of attending physicians (pmedical students' opinions on truth telling and attending physicians' actual clinical practice. More research is needed to objectively assess physicians' truth telling in clinical practice and to study the factors affecting the method of truth telling used by attending physicians in clinical practice.

  9. Political Corruption as Deformities of Truth

    Directory of Open Access Journals (Sweden)

    Yann Allard-Tremblay

    2014-01-01

    Full Text Available This paper presents a conception of corruption informed by epistemic democratic theory. I first explain the view of corruption as a disease of the political body. Following this view, we have to consider the type of actions that debase a political entity of its constitutive principal in order to assess corruption. Accordingly, we need to consider what the constitutive principle of democracy is. This is the task I undertake in the second section where I explicate democratic legitimacy. I present democracy as a procedure of social inquiry about what ought to be done that includes epistemic and practical considerations. In the third section, I argue that the problem of corruption for a procedural conception of democracy is that the epistemic value of the procedure is diminished by corrupted agents’ lack of concern for truth. Corruption, according to this view, consists in two deformities of truth: lying and bullshit. These deformities corrupt since they conceal private interests under the guise of a concern for truth. In the fourth section, I discuss the difficulties a procedural account may face in formulating solutions to the problem of corruption.

  13. The seventh servant: the implications of a truth drive in Bion's theory of 'O'.

    Grotstein, James S

    2004-10-01

    Drawing upon Bion's published works on the subjects of truth, dreaming, alpha-function and transformations in 'O', the author independently postulates that there exists a 'truth instinctual drive' that subserves a truth principle, the latter of which is associated with the reality principle. Further, he suggests, following Bion's postulation, that 'alpha-function' and dreaming/phantasying constitute unconscious thinking processes and that they mediate the activity of this 'truth drive' (quest, pulsion), which the author hypothesizes constitutes another aspect of a larger entity that also includes the epistemophilic component drive. It purportedly seeks and transmits as well as includes what Bion (1965, pp. 147-9) calls 'O', the 'Absolute Truth, Ultimate Reality, O' (also associated with infinity, noumena or things-in-themselves, and 'godhead') (1970, p. 26). It is further hypothesized that the truth drive functions in collaboration with an 'unconscious consciousness' that is associated with the faculty of 'attention', which is also known as 'intuition'. It is responsive to internal psychical reality and constitutes Bion's 'seventh servant'. O, the ultimate landscape of psychoanalysis, has many dimensions, but the one that seems to interest Bion is that of the emotional experience of the analysand's and the analyst's 'evolving O' respectively (1970, p. 52) during the analytic session. The author thus hypothesizes that a sense of truth presents itself to the subject as a quest for truth which has the quality and force of an instinctual drive and constitutes the counterpart to the epistemophilic drive. This 'truth quest' or 'drive' is hypothesized to be the source of the generation of the emotional truth of one's ongoing experiences, both conscious and unconscious. It is proposed that emotions are beacons of truth in regard to the acceptance of reality. The concepts of an emotional truth drive and a truth principle would help us understand why analysands are able to

[the LADEE mission ended with the crash-landing of the spacecraft on the lunar far side on April 17, 2014, capping a successful 140 day mission] .We also have launched our campaign to document lunar meteoroid impact flashes from the ground to supply ground truth to inform of any changes in dust concentration encountered by the spacecraft in orbit around the moon. To date I have received six reports of impact flashes or flash candidates from the group I am coordinating; other groups around the world may have more to add when all is said and done. In addition, plans are underway to prepare a program at Prairie View A&M University to involve our physics majors in lunar meteoroid, asteroid occultation, and other astronomical work through our Center for Astronomical Sciences and Technology. This facility will be a control center to not only involve physics majors, but also to include pre-service teachers and member of the outside community to promote pro-am collaborations.

After introducing the main philosophical positions in the field of scientific realism, I discuss and then counter the two main arguments against realism, namely the pessimistic meta-induction and the abstract and idealized character of scientific laws. I conclude by defending the view that well-confirmed physical theories are true only relatively to certain values of the variables that appear in the laws.

    Reduced mortality has been the predominant cause of the marked global population growth over the last 3/4 of a century. While improved child survival increases motivation to reduce fertility, it comes too little and too late to forestall substantial population growth. And, beyond motivation, couples need effective means to control their fertility. It is an inconvenient truth that reducing child mortality contributes considerably to the population growth destined to compromise the quality of life of many, particularly in sub-Saharan Africa. Vigorous child survival programming is of course imperative. Wide access to voluntary family planning can help mitigate that growth and provide many other benefits.

    Marina Vladimirovna Zavarkina

    Full Text Available Analyzing the manuscript of Andrei Platonov’s tale The Foundation Pit and his early journalism the author traces the evolution of Platonov’s views on the problem of the search for the truth. Analysis of the dynamic transcription of the The Foundation Pit manuscript enabled to show that by the end of the 1920s Platonov had abandoned rationalistic interpretations of the concept of «truth», including in its "Bogdanov’s edition". Platonov increasingly questioned the capabilities of socialist science, based on materialism, to fi nd out the truth about the world, and changed his views on work as the only method of learning the truth. He departed from the materialistic concept of learning and shifted towards the religious and philosophical tradition: in the end the formula of P. Florensky "truth-estina (to be in existence" is getting more and more essential and it is outlined a shift of the concept of “truth” from a cognitive-materialistic category (“invent” / “to do” truth to an ontological and moral category.

    In post-genocide Rwanda, in addition to gacaca courts, a truth commission is needed in order to promote justice and foster reconciliation. In the context of transitional justice, retributive justice, which seeks justice and focuses on the perpetrators, appears to be inadequate to lead a society towards reconciliation. Therefore, some forms of restorative justice, which emphasize the healing of the whole society, seem necessary. In Rwanda, gacaca courts and a truth commission are complementary...

    In daily life, we frequently encounter false claims in the form of consumer advertisements, political propaganda, and rumors. Repetition may be one way that insidious misconceptions, such as the belief that vitamin C prevents the common cold, enter our knowledge base. Research on the illusory truth effect demonstrates that repeated statements are easier to process, and subsequently perceived to be more truthful, than new statements. The prevailing assumption in the literature has been that knowledge constrains this effect (i.e., repeating the statement "The Atlantic Ocean is the largest ocean on Earth" will not make you believe it). We tested this assumption using both normed estimates of knowledge and individuals' demonstrated knowledge on a postexperimental knowledge check (Experiment 1). Contrary to prior suppositions, illusory truth effects occurred even when participants knew better. Multinomial modeling demonstrated that participants sometimes rely on fluency even if knowledge is also available to them (Experiment 2). Thus, participants demonstrated knowledge neglect, or the failure to rely on stored knowledge, in the face of fluent processing experiences. (c) 2015 APA, all rights reserved).

    Lightning rod connected with the ground resistance is an equipment protection against hazards of lightning strikes building. Lightning strike to the building may result in damage to the building and destroy all the equipment inside it. The need for a lightning rod of a building is regulated in PUIPP expressed with risk factors (FR). The amount of FR is the sum of the value of the index of five (5 ) components of the building i.e building functions, construction, the height and the situation of the building and and the number of yearly lightning days in that places. At this time 05 PSTA building has undergone changes in the function of the building's mechanical workshop into a cyclotron building so that safety criteria also change into vital building with lightning rods resistance have to < 1 Ω. From measurements of grounding resistant which exist at present known that average Rp is 1.26 Ω so it is necessary to install new additional grounding resistance to reduce being less than 1 Ω. To fulfil this and taking into consideration the cost and ease of installation, planned addition of a grounding using electrodes solid rods of copper, a diameter of 16 mm and a length of 4 m , planted the soil water depth of 12 m, as well as clay covering, with a water content of about 30 %. Under these conditions and taking into the cost and ease of installation are expected to obtain optimal results i.e. soil resistivity 18.35 Ω-m and its resistance of Rx 4.82 Ω. When coupled with existing grounding final resistant Rp 0.99 Ω obtained is thus fulfilling the requirements of PUIPP that is less than 1 Ω. (author)

    Since 2000, the truth campaign has grown as a social marketing brand. Back then, truth employed branding to compete directly with the tobacco industry. In 2014, the launch of truth FinishIt reflected changes in the brand's strategy, the tobacco control environment, and youth/young adult behavior. Building on a previous validation study, the current study examined brand equity in truth FinishIt , as measured by validated multi-dimensional scales, and tobacco related attitudes, beliefs, and behavior based on two waves of the Truth Longitudinal Cohort data from 2015 and 2016. A fixed effects logistic regression was used to estimate the change in brand equity between panel survey waves 3 and 4 on past 30-day smoking among ever and current smokers. Additional models determined the effects of brand equity predicting tobacco attitudes/use at follow up among the full sample. All analyses controlled for demographic factors.

    This study examined cross-cultural differences and similarities in children’s moral understanding of individual- or collective-oriented lies and truths. Seven-, 9-, and 11-year-old Canadian and Chinese children were read stories about story characters facing moral dilemmas about whether to lie or tell the truth to help a group but harm an individual or vice versa. Participants chose to lie or to tell the truth as if they were the character (Experiments 1 and 2) and categorized and evaluated the story characters’ truthful and untruthful statements (Experiments 3 and 4). Most children in both cultures labeled lies as lies and truths as truths. The major cultural differences lay in choices and moral evaluations. Chinese children chose lying to help a collective but harm an individual, and they rated it less negatively than lying with opposite consequences. Chinese children rated truth telling to help an individual but harm a group less positively than the alternative. Canadian children did the opposite. These findings suggest that cross-cultural differences in emphasis on groups versus individuals affect children’s choices and moral judgments about truth and deception. PMID:17352539

    With the advent of high-resolution CT, three-dimensional (3D) methods for nodule volumetry have been introduced, with the hope that such methods will be more accurate and consistent than currently used planar measures of size. However, the error associated with volume estimation methods still needs to be quantified. Volume estimation error is multi-faceted in the sense that there is variability associated with the patient, the software tool and the CT system. A primary goal of our current research efforts is to quantify the various sources of measurement error and, when possible, minimize their effects. In order to assess the bias of an estimate, the actual value, or "truth," must be known. In this work we investigate the reliability of micro CT to determine the "true" volume of synthetic nodules. The advantage of micro CT over other truthing methods is that it can provide both absolute volume and shape information in a single measurement. In the current study we compare micro CT volume truth to weight-density truth for spherical, elliptical, spiculated and lobulated nodules with diameters from 5 to 40 mm, and densities of -630 and +100 HU. The percent differences between micro CT and weight-density volume for -630 HU nodules range from [-21.7%, -0.6%] (mean= -11.9%) and the differences for +100 HU nodules range from [-0.9%, 3.0%] (mean=1.7%).

  12. Foresight for commanders: a methodology to assist planning for effects-based operations

    Looking at the battlespace as a system of systems is a cornerstone of Effects-Based Operations and a key element in the planning of such operations, and in developing the Commander's Predictive Environment. Instead of a physical battleground to be approached with weapons of force, the battlespace is an interrelated super-system of political, military, economic, social, information and infrastructure systems to be approached with diplomatic, informational, military and economic actions. A concept that has proved useful in policy arenas other than defense, such as research and development for information technology, addressing cybercrime, and providing appropriate and cost-effective health care, is foresight. In this paper, we provide an overview of how the foresight approach addresses the inherent uncertainties in planning courses of action, present a set of steps in the conduct of foresight, and then illustrate the application of foresight to a commander's decision problem. We conclude that foresight approach that we describe is consistent with current doctrinal intelligence preparation of the battlespace and operational planning, but represents an advance in that it explicitly addresses the uncertainties in the environment and planning in a way that identifies strategies that are robust over different possible ground truths. It should supplement other planning methods.

    2018-03-01

    Full Text Available Since 2000, the truth campaign has grown as a social marketing brand. Back then, truth employed branding to compete directly with the tobacco industry. In 2014, the launch of truth FinishIt reflected changes in the brand's strategy, the tobacco control environment, and youth/young adult behavior.Building on a previous validation study, the current study examined brand equity in truth FinishIt, as measured by validated multi-dimensional scales, and tobacco related attitudes, beliefs, and behavior based on two waves of the Truth Longitudinal Cohort data from 2015 and 2016. A fixed effects logistic regression was used to estimate the change in brand equity between panel survey waves 3 and 4 on past 30-day smoking among ever and current smokers. Additional models determined the effects of brand equity predicting tobacco attitudes/use at follow up among the full sample. All analyses controlled for demographic factors.A one-point increase in the brand equity scale between the two waves was associated with a 66% greater chance of not smoking among ever smokers (OR 1.66, CI 1.11–2.48, p<0.05 and an 80% greater chance of not smoking among current smokers (OR 1.80, CI 1.05–3.10, p<0.05. Higher overall truth brand equity at wave 3 predicted less smoking at wave 4 and more positive anti-tobacco attitudes. Being male, younger, and non-white predicted some of the tobacco related attitudes.Future research should examine long-term effects of brand equity on tobacco use and how tobacco control can optimize the use of branding in campaigns.

    Gillett, Grant

    2015-12-01

    Truth and knowledge are conceptually related and there is a way of construing both that implies that they cannot be solely derived from a description that restricts itself to a set of scientific facts. In the first section of this essay, I analyse truth as a relation between a praxis, ways of knowing, and the world. In the second section, I invoke the third thing-the objective reality on which we triangulate as knowing subjects for the purpose of complex scientific endeavours like medical science and clinical care. Such praxes develop robust methods of "keeping in touch" with disease and illness (like biomarkers). An analysis drawing on philosophical semantics motivates the needed (anti-scientistic) account of meaning and truth (and therefore knowledge) and underpins the following argument: (i) the formulation and dissemination of knowledge rests on language; (ii) language is selective in what it represents in any given situation; (iii) the praxes of a given (sub)culture are based on this selectivity; but (iv) human health and illness involve whole human beings in a human life-world; therefore, (v) medical knowledge should reflectively transcend, where required, biomedical science towards a more inclusive view. Parts three and four argue that a post-structuralist (Lacanian) account of the human subject can avoid both scientism and idealism or unconstrained relativism.

    Surface characteristics at the six sites where spacecraft have successfully landed on Mars can be related favorably to their signatures in remotely sensed data from orbit and from the Earth. Comparisons of the rock abundance, types and coverage of soils (and their physical properties), thermal inertia, albedo, and topographic slope all agree with orbital remote sensing estimates and show that the materials at the landing sites can be used as ground truth for the materials that make up most of the equatorial and mid- to moderately high-latitude regions of Mars. The six landing sites sample two of the three dominant global thermal inertia and albedo units that cover ~80% of the surface of Mars. The Viking, Spirit, Mars Pathfinder, and Phoenix landing sites are representative of the moderate to high thermal inertia and intermediate to high albedo unit that is dominated by crusty, cloddy, blocky or frozen soils (duricrust that may be layered) with various abundances of rocks and bright dust. The Opportunity landing site is representative of the moderate to high thermal inertia and low albedo surface unit that is relatively dust free and composed of dark eolian sand and/or increased abundance of rocks. Rock abundance derived from orbital thermal differencing techniques in the equatorial regions agrees with that determined from rock counts at the surface and varies from ~3-20% at the landing sites. The size-frequency distributions of rocks >1.5 m diameter fully resolvable in HiRISE images of the landing sites follow exponential models developed from lander measurements of smaller rocks and are continuous with these rock distributions indicating both are part of the same population. Interpretation of radar data confirms the presence of load bearing, relatively dense surfaces controlled by the soil type at the landing sites, regional rock populations from diffuse scattering similar to those observed directly at the sites, and root-mean-squared slopes that compare favorably

    Full Text Available Introduction. The article focuses on a topical conflict in contemporary medical practice – truthful patient’s information. Analysis of the problem is considered in historical perspective, by bringing the views of both domestic and foreign authors. Various opinions and arguments for and against providing information to the patient about his health discussions to this day by physicians, despite the legalization provision of truthful information about the state of health. Materials and Methods. Material for the article was the ethical and regulatory documents that include provisions on the right of the patient in receiving truthful information. On the basis of the dialectical approach in the article, the object of the research is a rule of truthfulness in medicine, the analysis which takes place in the framework of medical ethics and its modern model of bioethics. The application of integrated approach allowed us to consider the problem from a position of morality and law, society, medicine and the individual. Using the following methods: comparative-historical, axiological, document analysis, and synthesis of the functionality, efficiency and appropriateness of the rules of veracity at the present stage of development of medicine. Results. In the course of the study it was revealed that the issue of the rule of truthfulness in modern medical practice, justifying from the perspective of modern model of medical ethics – bioethics and the law, is the inalienable right of the patient. In addition, you specify the inextricable link between the rule and the truthfulness rule of informed consent. These regulations removed the controversial question of the presence of the “holy lie” in medicine. But due to the absolutely inviolable rules of “no harm” in medicine it is necessary to consider the ethical and legal aspects of rules of veracity: the duty, the right, the opportunity and feasibility to speak the truth, allowing not only the law

  4. Truth and modes of cognition in Boethius: a Neoplatonic approach

    Directory of Open Access Journals (Sweden)

    José María Zamora Calvo

    2017-07-01

    Full Text Available Boethius does not accept the principle of realism that considers truth as the adaptation – or adequation – of the subject to the knowable object, and instead defends that knowledge should be studied by relating it to the capacity of the cognoscente subject. Thus, truth is relative to the faculty or level of knowledge in which we stand, since each faculty -each level of knowledge- has its own object: the material figure for the senses, the figure without matter for the Imagination, the universal for reason and the simple form for intelligence. But this epistemological relativism is moderate, precisely because of its hierarchical character. Therefore, although in a sense truth is manifold, the perfect truth, proper to divine knowledge, includes and surpasses all others. In order to cement the architecture of this system of relativisation of knowledge, Boethius starts from a Neoplatonic interpretation of the simile of the line of the Republic (VI.510a-b and Plato's Timaeus, but not completely tied to it. The beings endowed with knowledge are ordered according to the Neoplatonic hierarchy of cosmic realities.

Although the text adresses the Social Sciences from the perspective of Social Anthropology, it deals with topics in which the researchers and ativists activities require a cooperative action of lawyers, engineers and biologists among the work of sociologists and geographers – all that is involved in the situations when it is necessary to tell the truth and also to judge about justice and injustice in social life. Justice and truth notions are social scientists weapons and they can not be abandoned in the hands of conservative thought.

    Full Text Available This article presents the implementation of the right to the truth of the victims, through the creation of eleven Commissions of Truth, established in Argentina, Chile, El Salvador, Guatemala, Uruguay, Peru, Paraguay, Colombia, Ecuador, Honduras and Brasil, which emerged as the product of peace agreements or transitional processes. The Commissions of Truth received the assignment to investigate violations of Human Rights and breaches of International Humanitarian Law by military dictatorships, authoritarian regimes or internal armed conflicts. This review shows, that in addition to the subjects that constitute the Commissions, they work due to eight conditions: determined duration; legitimacy; themes; working methodologies; media of dissemination of results; attention to Disarmament, Demobilization and Reintegration processes; repair strategies, request for forgiveness and reconciliation. The existence of the Commissions of Truth, while transforming the conflicts they serve, have not reached, as a strategy, the integral promotion of connivance and reconciliation.

    Di Nola, Antonio; Turunen, Esko

    2016-01-01

    This book presents the first algebraic treatment of quasi-truth fuzzy logic and covers the algebraic foundations of many-valued logic. It offers a comprehensive account of basic techniques and reports on important results showing the pivotal role played by perfect many-valued algebras (MV-algebras). It is well known that the first-order predicate Łukasiewicz logic is not complete with respect to the canonical set of truth values. However, it is complete with respect to all linearly ordered MV –algebras. As there are no simple linearly ordered MV-algebras in this case, infinitesimal elements of an MV-algebra are allowed to be truth values. The book presents perfect algebras as an interesting subclass of local MV-algebras and provides readers with the necessary knowledge and tools for formalizing the fuzzy concept of quasi true and quasi false. All basic concepts are introduced in detail to promote a better understanding of the more complex ones. It is an advanced and inspiring reference-guide for graduate s...

    The estimation of Snow Water Equivalent (SWE) is essential for an appropriate assessment of the available water resources in Alpine catchment. The hydrologic regime in these areas is dominated by the storage of water in the snowpack, which is discharged to rivers throughout the melt season. An accurate estimation of the resources will be necessary for an appropriate analysis of the system operation alternatives using basin scale management models. In order to obtain an appropriate estimation of the SWE we need to know the spatial distribution snowpack and snow density within the Snow Cover Area (SCA). Data for these snow variables can be extracted from in-situ point measurements and air-borne/space-borne remote sensing observations. Different interpolation and simulation techniques have been employed for the estimation of the cited variables. In this paper we propose to estimate snowpack from a reduced number of ground-truth data (1 or 2 campaigns per year with 23 observation point from 2000-2014) and MODIS satellite-based observations in the Sierra Nevada Mountain (Southern Spain). Regression based methodologies has been used to study snowpack distribution using different kind of explicative variables: geographic, topographic, climatic. 40 explicative variables were considered: the longitude, latitude, altitude, slope, eastness, northness, radiation, maximum upwind slope and some mathematical transformation of each of them [Ln(v), (v)^-1; (v)^2; (v)^0.5). Eight different structure of regression models have been tested (combining 1, 2, 3 or 4 explicative variables). Y=B0+B1Xi (1); Y=B0+B1XiXj (2); Y=B0+B1Xi+B2Xj (3); Y=B0+B1Xi+B2XjXl (4); Y=B0+B1XiXk+B2XjXl (5); Y=B0+B1Xi+B2Xj+B3Xl (6); Y=B0+B1Xi+B2Xj+B3XlXk (7); Y=B0+B1Xi+B2Xj+B3Xl+B4Xk (8). Where: Y is the snow depth; (Xi, Xj, Xl, Xk) are the prediction variables (any of the 40 variables); (B0, B1, B2, B3) are the coefficients to be estimated. The ground data are employed to calibrate the multiple regressions. In

    Effective positron emission tomography / computed tomography (PET/CT) guidance in radiotherapy of lung cancer requires estimation and mitigation of errors due to respiratory motion. An end-to-end workflow was developed to measure patient-specific motion-induced uncertainties in imaging, treatment planning, and radiation delivery with respiratory motion phantoms and dosimeters. A custom torso phantom with inserts mimicking normal lung tissue and lung lesion was filled with [(18)F]FDG. The lung lesion insert was driven by six different patient-specific respiratory patterns or kept stationary. PET/CT images were acquired under motionless ground truth, tidal breathing motion-averaged (3D), and respiratory phase-correlated (4D) conditions. Target volumes were estimated by standardized uptake value (SUV) thresholds that accurately defined the ground-truth lesion volume. Non-uniform dose-painting plans using volumetrically modulated arc therapy were optimized for fixed normal lung and spinal cord objectives and variable PET-based target objectives. Resulting plans were delivered to a cylindrical diode array at rest, in motion on a platform driven by the same respiratory patterns (3D), or motion-compensated by a robotic couch with an infrared camera tracking system (4D). Errors were estimated relative to the static ground truth condition for mean target-to-background (T/Bmean) ratios, target volumes, planned equivalent uniform target doses, and 2%-2 mm gamma delivery passing rates. Relative to motionless ground truth conditions, PET/CT imaging errors were on the order of 10-20%, treatment planning errors were 5-10%, and treatment delivery errors were 5-30% without motion compensation. Errors from residual motion following compensation methods were reduced to 5-10% in PET/CT imaging, PET/CT imaging to RT planning, and RT delivery under a dose painting paradigm is feasible within an integrated respiratory motion phantom workflow. For a limited set of cases, the magnitude

    Full Text Available This article addresses the status of the fact in literary and historical discourses in late colonial Korea, focusing on the elaboration of the relationship between scientific and literary truths primarily in the work of philosopher and critic Sŏ Insik (1906–?. It points to a growing tendency in late 1930s and early 1940s Korea to question the veracity of the fact (or of empiricism more broadly in an environment where the enunciation of the colonial subject had been rendered problematic and objective statements had arguably lost their connection with social reality. In a period when the relationship between signifier and referent had come into question, how did this major critic understand the relationship between science and literature, or between truth and subjectivity? Sŏ warns against a simplistic apprehension of the notion of truth as unilaterally equivalent with what he calls “scientific truth” (kwahakchŏk chilli—a nomological truth based on objective observation and confirmation by universal principles—and argues that a necessary complement to apparently objective truth is “literary truth” (munhakchŏk chinsil. Against the fixed, conceptual form of scientific thought, literary truth presents itself as an experiential truth that returns to the sensory world of the sociolinguistic subject (chuch’e as a source of credibility.

    2007-08-01

    Full Text Available Abstract The current practice of organ transplantation has been criticized on several fronts. The philosophical and scientific foundations for brain death criteria have been crumbling. In addition, donation after cardiac death, or non-heartbeating-organ donation (NHBD has been attacked on grounds that it mistreats the dying patient and uses that patient only as a means to an end for someone else's benefit. Verheijde, Rady, and McGregor attack the deception involved in NHBD, arguing that the donors are not dead and that potential donors and their families should be told that is the case. Thus, they propose abandoning the dead donor rule and allowing NHBD with strict rules concerning adequate informed consent. Such honesty about NHBD should be welcomed. However, NHBD violates a fundamental end of medicine, nonmaleficience, "do no harm." Physicians should not be harming or killing patients, even if it is for the benefit of others. Thus, although Verheijde and his colleages should be congratulated for calling for truthfulness about NHBD, they do not go far enough and call for an elimination of such an unethical procedure from the practice of medicine.

    Over the past decade, public education mass media campaigns have been shown to be successful in changing tobacco-related attitudes, intentions, and behaviors among youth and young adults. In 2014, the national truth® campaign re-launched a new phase of the campaign targeted at a broad audience of youth and young adults, aged 15-21, to help end the tobacco epidemic. The study sample for this analysis is drawn from the Truth Longitudinal Cohort (TLC), a probability-based, nationally representative cohort designed to evaluate the relationship between awareness of truth media messages and changes in targeted attitudes, beliefs, and behaviors over time. The sample for this study was limited to those with data at baseline and three subsequent follow-up surveys (n = 7536). Logistic regression models indicate that truth ad awareness is significantly associated with increases in targeted anti-tobacco attitudes as well as reduced intentions to smoke over time, holding constant baseline attitudes and intentions. Results also suggest a dose-response relationship in that higher levels of truth ad awareness were significantly associated with higher likelihood of reporting agreement across all five attitudinal constructs: anti-smoking imagery, anti-social smoking sentiment, anti-tobacco social movement, anti-tobacco industry sentiment, and independence. Longitudinal results indicate a significant dose-response relationship between awareness of the new phase of the truth campaign and campaign-targeted attitudes and intentions not to smoke among youth and young adults. Findings from this study confirm that a carefully designed anti-tobacco public education campaign aimed at youth and young adults is a key population-level intervention within the context of an expanding tobacco product landscape and a cluttered media environment. As tobacco use patterns shift and new products emerge, evidence-based public education campaigns can play a central role in helping the next generation to

    Full Text Available This study begins with a brief outline of the essence of the whole encyclical Caritas in veritate . Benedict XVI expresses the desire for „the dialogue with the world”. He understands this dialogue as a special kind of the service of the Church towards eternal love and truth, fully revealed in Christ. The dialogue of the Church with the world, in the spirit of love and truth, is accomplished every day at the level of so-called official relations. There are numerous opinions that in the past the Church repeatedly neglected the dialogue with the world. Indeed, the Church historians point out the existence of examples of the fall of the authority of the Holy See in particular countries and circumstances. Similarly, the Church is the sign of objection in the contemporary world. Instructed by past experiences the Church is aware that what is necessary for the renewal of culture and society, is evangelical love and truth.

  20. SU-E-J-76: Incorporation of Ultrasound Elastography in Target Volume Delineation for Partial Breast Radiotherapy Planning: A Comparative Study

    2014-06-01

    Purpose: There is substantial observer variability in the delineation of target volumes for post-surgical partial breast radiotherapy because the tumour bed has poor x-ray contrast. This variability may result in substantial variations in planned dose distribution. Ultrasound elastography (USE) has an ability to detect mechanical discontinuities and therefore, the potential to image the scar and distortion in breast tissue architecture. The goal of this study was to compare USE techniques: strain elastography (SE), shear wave elastography (SWE) and acoustic radiation force impulse (ARFI) imaging using phantoms that simulate features of the tumour bed, for the purpose of incorporating USE in breast radiotherapy planning. Methods: Three gelatine-based phantoms (10% w/v) containing: a stiff inclusion (gelatine 16% w/v) with adhered boundaries, a stiff inclusion (gelatine 16% w/v) with mobile boundaries and fluid cavity inclusion (to mimic seroma), were constructed and used to investigate the USE techniques. The accuracy of the elastography techniques was quantified by comparing the imaged inclusion with the modelled ground-truth using the Dice similarity coefficient (DSC). For two regions of interest (ROI), the DSC measures their spatial overlap. Ground-truth ROIs were modelled using geometrical measurements from B-mode images. Results: The phantoms simulating stiff scar tissue with adhered and mobile boundaries and seroma were successfully developed and imaged using SE and SWE. The edges of the stiff inclusions were more clearly visible in SE than in SWE. Subsequently, for all these phantoms the measured DSCs were found to be higher for SE (DSCs: 0.91–0.97) than SWE (DSCs: 0.68–0.79) with an average relative difference of 23%.

    Juneja, P; Harris, E; Bamber, J

    2014-01-01

    Purpose: There is substantial observer variability in the delineation of target volumes for post-surgical partial breast radiotherapy because the tumour bed has poor x-ray contrast. This variability may result in substantial variations in planned dose distribution. Ultrasound elastography (USE) has an ability to detect mechanical discontinuities and therefore, the potential to image the scar and distortion in breast tissue architecture. The goal of this study was to compare USE techniques: strain elastography (SE), shear wave elastography (SWE) and acoustic radiation force impulse (ARFI) imaging using phantoms that simulate features of the tumour bed, for the purpose of incorporating USE in breast radiotherapy planning. Methods: Three gelatine-based phantoms (10% w/v) containing: a stiff inclusion (gelatine 16% w/v) with adhered boundaries, a stiff inclusion (gelatine 16% w/v) with mobile boundaries and fluid cavity inclusion (to mimic seroma), were constructed and used to investigate the USE techniques. The accuracy of the elastography techniques was quantified by comparing the imaged inclusion with the modelled ground-truth using the Dice similarity coefficient (DSC). For two regions of interest (ROI), the DSC measures their spatial overlap. Ground-truth ROIs were modelled using geometrical measurements from B-mode images. Results: The phantoms simulating stiff scar tissue with adhered and mobile boundaries and seroma were successfully developed and imaged using SE and SWE. The edges of the stiff inclusions were more clearly visible in SE than in SWE. Subsequently, for all these phantoms the measured DSCs were found to be higher for SE (DSCs: 0.91–0.97) than SWE (DSCs: 0.68–0.79) with an average relative difference of 23%. In the case of seroma phantom, DSC values for SE and SWE were similar. Conclusion: This study presents a first attempt to identify the most suitable elastography technique for use in breast radiotherapy planning. Further analysis will

    In 2015, the Academy for Eating Disorders collaborated with international patient, advocacy, and parent organizations to craft the 'Nine Truths About Eating Disorders'. This document has been translated into over 30 languages and has been distributed globally to replace outdated and erroneous stereotypes about eating disorders with factual information. In this paper, we review the state of the science supporting the 'Nine Truths'. The literature supporting each of the 'Nine Truths' was reviewed, summarized and richly annotated. Most of the 'Nine Truths' arise from well-established foundations in the scientific literature. Additional evidence is required to further substantiate some of the assertions in the document. Future investigations are needed in all areas to deepen our understanding of eating disorders, their causes and their treatments. The 'Nine Truths About Eating Disorders' is a guiding document to accelerate global dissemination of accurate and evidence-informed information about eating disorders.

  4. Hospital development plans: a new tool to break ground for strategic thinking in Tanzanian hospitals.

    Science.gov (United States)

    Flessa, Steffen

    2005-12-01

    Tanzanian hospitals suffer from underfunding and poor management. In particular, planning and strategic thinking need improvement. Cultural values such as subordination, risk aversion, and high time preference, together with a long history of socialist government, result in lack of responsibility, accountability, and planning. This has been addressed by the health sector reform with its focus on decentralization, strengthened by the introduction of basket funding facilitated by the Comprehensive Council Health Plans. As a consequence of this the next logical step is to improve the authority of regional and district hospitals in the use of their resources by introducing hospital development plans. These strategic plans were introduced as tools of strategic planning in 2001 by the Kreditanstalt für Wiederaufbau in close collaboration with the Tanzanian Ministry of Health, binding the release of rehabilitation funds to presentation of a strategic hospital plan. This study examines the rationale and content of hospital development plans. Initial experiences are discussed. The quality of presented plans has steadily improved, but there is a tendency for hospitals with a close connection to development partners to present well prepared reports while other hospitals have severe problems fulfilling the requirements. For many hospitals it is in fact the first time that they have had to define their functions and future role, thus breaking ground for strategic thinking.

    1994-09-01

    The scope of the Project is to develop and implement a ground water compliance strategy for all 24 UMTRA Project processing sites. The compliance strategy for the processing sites must satisfy the proposed EPA ground water cleanup standards in 40 CFR Part 192, Subparts B and C (1987). This scope of work will entail the following activities on a site-specific basis: Develop a compliance strategy based on modification of the UMTRA Surface Project RAPs or develop Ground Water Project RAPs with NRC concurrence on the RAP and full participation of the affected states and tribes. Implement the RAP to include institutional controls, where appropriate, as an interim measure until compliance with the standards is achieved. Institute long-term verification monitoring for transfer to a separate long-term surveillance program on or before the Project end date. Prepare certification or confirmation reports and modify the long-term surveillance plan (LTSP), where needed, on those sites completed prior to the Project end date

  9. On Truth and Emancipation

    Directory of Open Access Journals (Sweden)

    Andreas Hjort Bundgaard

    2012-09-01

    Full Text Available This article has two main currents. First, it argues that an affinity or similarity can be identified between the philosophy of Gianni Vattimo (the so-called “Weak Thinking” and the “Discourse Theory” of Ernesto Laclau and Chantal Mouffe. The two theorizations are engaged with related problems, but have conceptualized them differently; they share central insights, but understand them with different vocabularies. The article furthermore illuminates as regards what this affinity consists in, and it discusses the differences and similarities between the two theoretical positions. The second current of the article takes the ‘postmodern’ philosophical problems of anti-foundationalism and nihilism as its point of departure. It raises the questions of: 1 how it is possible at the same time to take the critique of universality and objectivity seriously and still believe in the value of ethics and science; and, 2 how we are to understand emancipation if there is no necessary relationship between truth and freedom. The article investigates the status, meaning and interconnection of the categories of truth, knowledge, ethics, politics and emancipation in the light of the absence of metaphysical first principles. The article concludes that: A faith can constitute a “weak foundation” of knowledge and ethics; and, B nihilism can be combined with the political and ethical ambitions of universal human emancipation and radical democracy.

    2006-01-01

    Lakeland County is experiencing increasing developmental pressures arising from the oil and gas boom at nearby Fort McMurray. There is increased industrial traffic passing through the county, and 600 new residential lots are proposed in 2005, almost double from 5 years ago. Deteriorating surface water quality has been a concern in the area due to an increase in development and agriculture, while excessive fish harvesting and winterkills have impacted commercial and recreational fisheries. Today, walleye and pike populations in the lake remain collapsed and restocking efforts have not been successful. Due to the lack of studies done on the watershed, the county is leading a multidisciplinary research study which includes a baseline water quality study, riparian health assessments, land use mapping and ground-truthing and projects with the local health authority. This research has been summarized in a comprehensive state of the watershed report, which will be used to complete a watershed management plan for the Lac la Biche watershed. Recommendations from the state of the watershed report and watershed management plan will also be incorporated into municipal planning documents and recommend changes to the Municipal Government Act itself.

    2017-08-01

    This essay was written almost ten years ago when the urgency of America's failure as a nation to respond to the threats of climate change first came to preoccupy me. Although the essay was never published in full, I circulated it informally in an attempt to provoke a more public engagement among my colleagues in the history, philosophy, and sociology of science. In particular, it was written in almost direct response to Philip Kitcher's own book, Science, Truth and Democracy (2001), in an attempt to clarify what was special about Climate Science in its relation to truth and democracy. Kitcher's response was immensely encouraging, and it led to an extended dialogue that resulted, first, in a course we co-taught at Columbia University, and later, to the book The Seasons Alter: How to Save Our Planet in Six Acts (W. W. Norton) published this spring. The book was finished just after the Paris Climate Accord, and it reflects the relative optimism of that moment. Unfortunately events since have begun to evoke, once again, the darker mood of this essay. I am grateful to Greg Radick for suggesting its publication. Copyright © 2017 Elsevier Ltd.

  13. The ethics of truth in the era of technological civilization and the information

    Directory of Open Access Journals (Sweden)

    N. V. Nesprava

    2017-01-01

    Full Text Available The technological civilization and information society give a lot of advantages to a modern man in various fields. However, at the same time, we do not see a decrease in hostility and injustice in the society. Moreover, technological progress has led to the fact that human civilization is on the verge of a serious challenge caused by environmental disasters and opportunity for unprecedented disastrous consequences of the World War III. In these circumstances, the search for the causes of the current crisis is actual as well as the development of concepts that can contribute to overcoming this crisis. One of the most promising theories in this context is the ethics of truth. In modern civilization the issue of the importance of truth is shifted to the periphery of the intellectual discourse. Modern civilization uses only substitutes of the issue. Veracity in science together with popular opinions in the field of information circulating are such substitutes of truth. However, these substitutes do not fully reflect the true contents of the truth issue. The truth is not confined to the veracity of a celebrity’s opinion. Analyzing the theories by H. Jonas, В. Hübner, V. Stepin and T. Voronina, the study argues that the processes of losing of the meaning of life are intensifying in the modern civilization. We argue that a lack of a proper attention in modern civilization to the issue of truth inevitably stimulates processes of diluting the meaning of human life. Based on the theories by G. Hegel, H.-G. Gadamer and J. Neidleman T. Osborne, the study demonstrates that without thinking about the issue of the truth one cannot come near to the transcendent, and thus, his life could not be convincingly endowed with meaning, fullness and a purpose of existence. Understanding the issue of truth is especially important in conditions of the modern civilization, because our civilization is facing the possibility of self-destruction as a result of its

    2010-05-01

    Full Text Available In the past year, the Government of Canada has established the Indian Residential Schools (IRS Truth and Reconciliation Commission (TRC to address the deleterious effect that the IRS system has had on Aboriginal communities. This paper argues that the TRC as an alternative dispute resolution mechanism is flawed since it focuses too much on truth at the expense of reconciliation. While the proliferation of historical truths is of great importance, without mapping a path to reconciliation, the Canadian public will simply learn about the mistakes of the past without addressing the residual, communal impacts of the IRS system that continue to linger. The Truth and Reconciliation Commission must therefore approach its mandate broadly and in a manner reminiscent of the Royal Commission on Aboriginal Peoples of 1996.

    Effective positron emission tomography / computed tomography (PET/CT) guidance in radiotherapy of lung cancer requires estimation and mitigation of errors due to respiratory motion. An end-to-end workflow was developed to measure patient-specific motion-induced uncertainties in imaging, treatment planning, and radiation delivery with respiratory motion phantoms and dosimeters. A custom torso phantom with inserts mimicking normal lung tissue and lung lesion was filled with [ 18 F]FDG. The lung lesion insert was driven by six different patient-specific respiratory patterns or kept stationary. PET/CT images were acquired under motionless ground truth, tidal breathing motion-averaged (3D), and respiratory phase-correlated (4D) conditions. Target volumes were estimated by standardized uptake value (SUV) thresholds that accurately defined the ground-truth lesion volume. Non-uniform dose-painting plans using volumetrically modulated arc therapy were optimized for fixed normal lung and spinal cord objectives and variable PET-based target objectives. Resulting plans were delivered to a cylindrical diode array at rest, in motion on a platform driven by the same respiratory patterns (3D), or motion-compensated by a robotic couch with an infrared camera tracking system (4D). Errors were estimated relative to the static ground truth condition for mean target-to-background (T/B mean ) ratios, target volumes, planned equivalent uniform target doses, and 2%-2 mm gamma delivery passing rates. Relative to motionless ground truth conditions, PET/CT imaging errors were on the order of 10–20%, treatment planning errors were 5–10%, and treatment delivery errors were 5–30% without motion compensation. Errors from residual motion following compensation methods were reduced to 5–10% in PET/CT imaging, <5% in treatment planning, and <2% in treatment delivery. We have demonstrated that estimation of respiratory motion uncertainty and its propagation from PET/CT imaging to RT

    This report consists of 2 subjects. (1) Consideration of the restoring plan in subsidence prone areas through the development of ground stability assessment techniques : The number of mines at rest as well as closed have abruptly increased since the 1980's, which has caused subsidence problems around the mined areas. To protect such places from damage due to subsidence, it is necessary to develop the assessment techniques of ground stability and make restoration plan. To achieve this goal, the site investigation should have been conducted before the subsidence events occurred, but ground behaviors around the places where a vertical movement is expected and recognised in advance before the occurrence of the subsidence events. In this study ground stability analysis for the area surrounding the Moo-Geuk Mine, located close to a city, was conducted and the measurements were recorded. The objectives of the present study include, the development of a risk assessment technique for the subsidence using GIS tool, an evaluation of the numerical methods related to the site investigation and the ground stability analysis, the application of the numerical tools to the present problems. (2) Integration of coal mine data and use of remote sensing in investigation of coal mine area : This study attempt to integrate the previous geological and mining data to avoid confusions often occurred when accessing source data. And the investigation of underground mining place using remote sensing method is the other effort to assure the geographic locations of mining places as well as to find out unknown mining place. The sample region for examining the remote sensing method is the Chungnam coal field, which locates in the middle western part of South Korea. Detailed investigation was held on the Seongju area, locating north eastern part of the coal field. (author). 54 refs., tabs., figs.

  19. A novel rumor diffusion model considering the effect of truth in online social media

    Science.gov (United States)

    Sun, Ling; Liu, Yun; Zeng, Qing-An; Xiong, Fei

    2015-12-01

    In this paper, we propose a model to investigate how truth affects rumor diffusion in online social media. Our model reveals a relation between rumor and truth — namely, when a rumor is diffusing, the truth about the rumor also diffuses with it. Two patterns of the agents used to identify rumor, self-identification and passive learning are taken into account. Combining theoretical proof and simulation analysis, we find that the threshold value of rumor diffusion is negatively correlated to the connectivity between nodes in the network and the probability β of agents knowing truth. Increasing β can reduce the maximum density of the rumor spreaders and slow down the generation speed of new rumor spreaders. On the other hand, we conclude that the best rumor diffusion strategy must balance the probability of forwarding rumor and the probability of agents losing interest in the rumor. High spread rate λ of rumor would lead to a surge in truth dissemination which will greatly limit the diffusion of rumor. Furthermore, in the case of unknown λ, increasing β can effectively reduce the maximum proportion of agents who do not know the truth, but cannot narrow the rumor diffusion range in a certain interval of β.

The specificity for PCa was found to be 75.43% with a positive predictive value of 61.11%, a negative predictive value of 63.23% and a false discovery rate of 38.89%. CAD classified PCa and benign lesions with equal probability (P 0.06, χ2 test. Accordingly, receiver operating characteristic analysis suggests a poor predictive value for MAI with an area under curve of 0.65 (P 0.02, which is not superior to the performance of board certified observers. Moreover, MAI revealed no significant correlation with Gleason grade (P 0.60, Pearson´s correlation.The tested CAD software for mpMRI analysis was a weak PCa biomarker in this dataset.

    Our climate crisis may at times appear to be happening slowly, but in fact it is happening very quickly-and has become a true planetary emergency. The Chinese expression for crisis consists of two characters. The first is a symbol for danger; the second is a symbol for opportunity. In order to face down the danger that is stalking us and move through it, we first have to recognize that we are facing a crisis. So why is it that our leaders seem not to hear such clarion warnings? Are they resisting the truth because they know that the moment they acknowledge it, they will face a moral imperative to act? Is it simply more convenient to ignore the warnings? Perhaps, but inconvenient truths do not go away just because they are not seen. Indeed, when they are responded to, their significance does not diminish; it grows. (author)

    Temporality and uncertainty are important features of many real world systems. Solving problems in such systems requires the use of formal mechanism such as logic systems, statistical methods or other reasoning and decision-making methods. In this paper, we propose a linguistic truth-valued temporal reasoning formalism to enable the management of both features concurrently using a linguistic truth valued logic and a temporal logic. We also provide a backward reasoning algorithm which allows the answering of user queries. A simple but realistic scenario in a smart home application is used to illustrate our work.

    "Truth" has been used as a baseline condition in several functional magnetic resonance imaging (fMRI) studies of deception. However, like deception, telling the truth is an inherently social construct, which requires consideration of another person's mental state, a phenomenon known as Theory of Mind. Using a novel ecological paradigm, we examined blood oxygenation level dependent (BOLD) responses during social and simple truth telling. Participants (n = 27) were randomly divided into two competing teams. Post-competition, each participant was scanned while evaluating performances from in-group and out-group members. Participants were asked to be honest and were told that their evaluations would be made public. We found increased BOLD responses in the medial prefrontal cortex, bilateral anterior insula and precuneus when participants were asked to tell social truths compared to simple truths about another person. At the behavioral level, participants were slower at responding to social compared to simple questions about another person. These findings suggest that telling the truth is a nuanced cognitive operation that is dependent on the degree of mentalizing. Importantly, we show that the cortical regions engaged by truth telling show a distinct pattern when the task requires social reasoning.

  13. Prosecuting International Crimes at National Level: Lessons from the Argentine ‘Truth-Finding Trials’

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Truth-finding trials (juicios por la verdad constitute a novel solution devised by the Argentine judicial system to cope with crimes committed by the past military dictatorship. This mechanism uses criminal courts as well as criminal procedure in order to investigate the truth about the dictatorship's crimes; however, the trials allow judges neither to establish criminal responsibility nor to punish the perpetrators of crimes. This limitation is due to the inability, imposed by the Full Stop and Due Obedience Laws, to prosecute the perpetrators of crimes.From the perspective of criminal law, truth-finding trials present two problematic features: firstly, their creation and regulation are set by judges, which has caused the development of many non-homogeneous local solutions and, secondly, their hybrid nature, which entails a possible subversion of conventional forms and goals in the context of the criminal trial.The paper also describes the current situation, since the Argentine impunity laws were declared unconstitutional and criminal proceedings reopened. The new framework provokes questions about the relationship between the reopened criminal trials and the truth-finding investigations, not only with regard to evidentiary issues but also with respect to the reason why the truth-finding investigations are still held.Finally, the shift from a non-punitive approach to the current full criminal accountability seems to suggest that truth-finding trials were merely a temporary solution, while the notion of the full prosecution and punishment of State crimes was never really set aside.

  14. Davidson, Dualism, and Truth

    Full Text Available Happy accidents happen even in philosophy. Sometimes our arguments yield insights despite missing their target, though when they do others can often spot it more easily. Consider the work of Donald Davidson. Few did more to explore connections among mind, language, and world. Now that we have critical distance from his views, however, we can see that Davidson’s accomplishments are not quite what they seem. First, while Davidson attacked the dualism of conceptual scheme and empirical content, he in fact illustrated a way to hold it. Second, while Davidson used the principle of charity to argue against the dualism, his argument in effect treats the principle as constitutive of a conceptual scheme. And third, while Davidson asserted that he cannot define what truth ultimately is—and while I do not disagree—his work nonetheless allows us to saymore about truth than Davidson himself does. I aim to establish these three claims. Doing so enriches our understanding of issues central to the history of philosophy concerning how, if at all, to divvy up the mental or linguistic contribution, and the worldly contribution, to knowledge. As we see below, Davidson was right in taking his work to be one stage of a dialectic begun by Immanuel Kant.1 He was just wrong about what that stage is. Reconsidering Davidson’s views also moves the current debate forward, as they reveal a previously unrecognized yet intuitive notion of truth—even if Davidson himself remained largely unaware of it. We begin however with scheme/content dualism and Davidson’s argument against it.

  15. About the notion of truth in quantum mechanics

    International Nuclear Information System (INIS)

    Omnes, R.

    1991-01-01

    The meaning of truth in quantum mechanics is considered in order to respond to some objections raised by B. d'Espagnat against a logical interpretation of quantum mechanics recently proposed by the author. A complete answer is given. It is shown that not only can factual data be said to be true, but also some of their logical consequences, so that the definition of truth given by Heisenberg is both extended and refined. Some nontrue but reliable propositions may also be used, but they are somewhat arbitrary because of the complementarity principle. For instance, the propositions expressing wave packet reduction can be either true or reliable, according to the case under study. Separability is also discussed: as far as the true properties of an individual system are concerned, quantum mechanics is separable

    2009-05-01

    In 2005, the American Journal of Public Health published an article that indicated that 22% of the overall decline in youth smoking that occurred between 1999 and 2002 was directly attributable to the truth social marketing campaign launched in 2000. A remaining key question about the truth campaign is whether the economic investment in the program can be justified by the public health outcomes; that question is examined here. Standard methods of cost and cost-utility analysis were employed in accordance with the U.S. Panel on Cost-Effectiveness in Health and Medicine; a societal perspective was employed. During 2000-2002, expenditures totaled just over $324 million to develop, deliver, evaluate, and litigate the truth campaign. The base-case cost-utility analysis result indicates that the campaign was cost saving; it is estimated that the campaign recouped its costs and that just under $1.9 billion in medical costs was averted for society. Sensitivity analysis indicated that the basic determination of cost effectiveness for this campaign is robust to substantial variation in input parameters. This study suggests that the truth campaign not only markedly improved the public's health but did so in an economically efficient manner.

    2017-10-01

    The label 'post-truth' signals for many a troubling turn away from principles of enlightened government. The word 'post', moreover, implies a past when things were radically different and whose loss should be universally mourned. In this paper, we argue that this framing of 'post-truth' is flawed because it is ahistorical and ignores the co-production of knowledge and norms in political contexts. Debates about public facts are necessarily debates about social meanings, rooted in realities that are subjectively experienced as all-encompassing and complete, even when they are partial and contingent. Facts used in policy are normative in four ways: They are embedded in prior choices of which experiential realities matter, produced through processes that reflect institutionalized public values, arbiters of which issues are open to democratic contestation and deliberation, and vehicles through which polities imagine their collective futures. To restore truth to its rightful place in democracy, governments should be held accountable for explaining who generated public facts, in response to which sets of concerns, and with what opportunities for deliberation and closure.

  1. Twardowski On Truth

    Directory of Open Access Journals (Sweden)

    Peter Simons

    2009-10-01

    Full Text Available Of those students of Franz Brentano who went on to become professional philosophers, Kazimierz Twardowski (1866-1938 is much less well-known than his older contemporaries Edmund Husserl and Alexius Meinong. Yet in terms of the importance of his contribution to the history of philosophy, he ranks among Brentano’s students behind at most those two, possibly only behind Husserl. The chief contribution of Twardowski to global philosophy came indirectly, through the influence of his theory of truth on his students, and they on their students, and so on. The most important of these grandstudents is one whom Twardowski presumably knew but never taught, and whose adopted name is obtained by deleting four letters from his own: Tarski.

    The present study examined Chinese children's moral evaluations of truths and lies about one's own pro-social acts. Children ages 7, 9, and 11 were read vignettes in which a protagonist performs a good deed and is asked about it by a teacher, either in front of the class or in private. In response, the protagonist either tells a modest lie, which is highly valued by the Chinese culture, or tells an immodest truth, which violates the Chinese cultural norms about modesty. Children were asked to identify whether the protagonist's statement was the truth or a lie, and to evaluate how 'good' or 'bad' the statement was. Chinese children rated modest lies more positively than immodest truths, with this effect becoming more pronounced with age. Rural Chinese children and those with at least one nonprofessional parent rated immodest truths less positively when they were told in public rather than in private. Furthermore, Chinese children of parents with high collectivism scores valued modest lies more than did children of parents with low collectivism scores. These findings suggest that both macro- and micro-cultural factors contribute significantly to children's moral understanding of truth and lie telling.

Given that human beings are selfish in nature, it is crucial yet challenging to design an efficient and truthful incentive mechanism to encourage users to participate. To address the challenge, we propose a novel truthful online auction mechanism that can efficiently learn to make irreversible online decisions on winner selections for new MCS systems without requiring previous knowledge of users. Moreover, we theoretically prove that our incentive possesses truthfulness, individual rationality and computational efficiency. Extensive simulation results under both real and synthetic traces demonstrate that our incentive mechanism can reduce the payment of the platform, increase the utility of the platform and social welfare.

  6. Extrametodical truth and ontology of the praxis: The mediator rationality of the phronesis

    Directory of Open Access Journals (Sweden)

    Gaetano Chiurazzi

    2016-05-01

    Full Text Available Gadamer’s vindication of the extra-methodical feature of truth in the human sciences put forward in Truth and Method does not mean a mere refusal of method: rather, it arises from the awareness that there are truths which are not reducible to the conditions of repeatability and commensurability set up by methodical thinking. In fact, the truths of the human sciences refer to the ontological dimension of the contingent and the accidental, i.e. to the dimension of the historical. In this essay I aim at highlighting this ontological dimension, which for Aristotle is eminently that of the praxis and of human action. I will show that such an ontology is a consequence of the logical and ontological discussions which crisscrossed Greek thought after the discovery of the incommensurable magnitudes. The ontology of praxis is an ontology which takes into account the “irrationality” represented by the contingent, the accidental, to which a new form of rationality corresponds: that of phrónesis. Phrónesis is in fact not a commensurative but a mediative rationality

In the wake of philosophy the teaching of philosophy reconciled with the destruction of the truth. Then the didactics of philosophy resigned from the placing the aim to the truth among the objectives, which should serve to philosophical education. III. The absence and understatement of the disinterested pursuit to the truth among the objectives or requirements of education impoverish the philosophical education and cause damage to the children, pupils and wards.

  10. THE JOURNEY OF TRUTH: FROM PLATO TO ZOLA

    Directory of Open Access Journals (Sweden)

    Ribut Basuki

    1999-01-01

    Full Text Available Western theater theory and criticism is generally considered to be set forth by the Greeks. Plato was "the first theater critic" with his negative comments about theater owing to his idealistic views about "the truth." Then came Aristotle who used a different viewpoint from that of Plato, saying that there is "truth" in theater. However, hostile criticism on theater came back in the Middle Ages, championed by Tertulian before Aristotelian theory was revived by the neo-classicists such as Scaliger and Castelvetro. Theater theory and criticism discourse was then made more alive by the romanticists who disagreed with the neo-classicists' rigid rules on theater. As the influence of science became dominant in the theater world, naturalism and realism emerged and became the mainstream of theater theory and criticism until well into the twentieth century.

  11. Should physicians tell the truth without taking social complications into account? A striking case.

    2018-03-01

    The principle of respect for autonomy requires informing patients adequately and appropriately about diagnoses, treatments, and prognoses. However, some clinical cases may cause ethical dilemmas regarding telling the truth. Under the existence especially of certain cultural, social, and religious circumstances, disclosing all the relevant information to all pertinent parties might create harmful effects. Even though the virtue of telling the truth is unquestionable, sometimes de facto conditions compel physicians to act paternalistically to protect the patient/patients from imminent dangers. This article, which aims to study the issue of whether a physician should always tell the truth, analyzes an interesting case that represents the detection of misattributed paternity during pre-transplant tests for a kidney transplant from the son to the father in Turkey, where social, cultural, and religious factors have considerable impact on marital infidelity. After analyzing the concept of telling the truth and its relationship with paternalism and two major ethical theories, consequentialism and deontology, it is concluded that the value of the integrity of life and survival overrides the value of telling the truth. For this reason, in the case of a high possibility of severe and imminent threats, withholding some information is ethically justifiable.

Throughout the text, we have used to illustrate some iconic films that bring notions of masculinity and femininity. The film we have chosen are works that have a distinct esthetic and markets, they are able to raise issues related to gender and sexuality in discussions against romantic love, identity, homosexuality, violence and techniques confession of truths, among others. We analyze the films from Michel Foucault perspective concern sexuality and power relations and Judith Butler about gender intelligible. The plots of the films show that such truths are constantly negotiated and further indicate that norms about sex, desire, pleasure, masculinity and femininity are not only reproduced as its effects on private plots do not end with the end of the film.

    In June 1987, the RCRA Closure/Postclosure Plan for the Bear Creek Burial Grounds (BCBG) was submitted to the Tennessee Department of Environment and Conservation (TDEC) for review and approval. TDEC modified and issued the plan approved on September 30, 1987. Subsequently, this plan was modified again and approved as Y/TS-395, Revised RCRA Closure Plan for the Bear Creek Burial Grounds (February 29, 1988). Y/TS-395 was initially intended to apply to A Area, C-West, B Area, and the Walk-In Pits of BCBG. However, a concept was developed to include the B Area (non-RCRA regulated) in the Walk-In Pits so that both areas would be closed under one cap. This approach included a tremendous amount of site preparation with an underlying stabilization base of 16 ft of sand for blast protection. The plan was presented to the state of Tennessee on March 8, 1990, and the Department of Energy was requested to review other unique alternatives to close the site. This amended closure plan goes further to include inspection and maintenance criteria along with other details

    The "truth" campaign was created to change youth attitudes about tobacco and to reduce teen tobacco use throughout Florida by using youth-driven advertising, public relations, and advocacy. Results of the campaign include a 92 percent brand awareness rate among teens, a 15 percent rise in teens who agree with key attitudinal statements about smoking, a 19.4 percent decline in smoking among middle school students, and a 8.0 percent decline among high school students. States committed to results-oriented youth anti-tobacco campaigns should look to Florida's "truth" campaign as a model that effectively places youth at the helm of anti-tobacco efforts.

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

  20. Ground water investigations in connection with planned energy wells in the Lena area, Melhus centre

    2000-01-01

    In March 2000 the Norwegian Geologic Survey (NGU) was requested to carry out ground water investigations in the Lena area at Melhus centre by the firms E-Tek AS and Statoil. The background for the investigations was the plans of exploiting ground heat connected to a housing project lead by Selmer Bolig AS. The aim of the project was to document the possibilities for extracting ground heat from loose soil well(s) in the selected construction area. The needed amount of water is in the size of 50 m 3 /hour (14l/s). In addition the conditions of currents, ground water quality and possibilities for refiltering of the ground water was to be mapped. In conclusion it may be said that it most likely will be possible to meet the stipulated water requirements (50 m 3 /hour) by establishing a full scale production well within the construction area. The ground water currents in the Lena area run from north to south. The ground water surface is relatively flat with an incline of 0.1 - 0.2 % (1-2 mm/m). The possibilities for refiltering pumped water seem to be good. The conditions should be mapped more closely through refiltering tests. All of the collected ground water samples exceed the limiting values stipulated by the drinking water regulations as to alkalinity, sulphate, calcium, potassium and manganese. The tests from Obs2 and from the ''municipal well'' exceed the limits for chloride and sodium as well. This indicates that unwanted precipitations of both chalk and manganese may occur. Large quantities of sea salts (chloride and sodium) may also have a corrosive effect. Through calculations using the Ryznar's Stability Index (RSI) it is evident that the tests from Obs1 and Obs2 are in the limiting area between ''problem free water'' and ''corrosive water'', while the water from the municipal well must be characterised as very corrosive. According to information from the managing personnel there have not been registered problems with precipitations or corrosion in heat

  1. The impact of culture and religion on truth telling at the end of life.

    2011-12-01

    Truth telling, a cardinal rule in Western medicine, is not a globally shared moral stance. Honest disclosure of terminal prognosis and diagnosis are regarded as imperative in preparing for the end of life. Yet in many cultures, truth concealment is common practice. In collectivist Asian and Muslim cultures, illness is a shared family affair. Consequently, decision making is family centred and beneficence and non-malfeasance play a dominant role in their ethical model, in contrast to patient autonomy in Western cultures. The 'four principles' are prevalent throughout Eastern and Western cultures, however, the weight with which they are considered and their understanding differ. The belief that a grave diagnosis or prognosis will extinguish hope in patients leads families to protect ill members from the truth. This denial of the truth, however, is linked with not losing faith in a cure. Thus, aggressive futile treatment can be expected. The challenge is to provide a health care service that is equable for all individuals in a given country. The British National Health Service provides care to all cultures but is bound by the legal principles and framework of the UK and aims for equity of provision by working within the UK ethical framework with legal and ethical norms being explained to all patients and relatives. This requires truth telling about prognosis and efficacy of potential treatments so that unrealistic expectations are not raised.

  6. Unearthing Truth: Forensic Anthropology, Translocal Memory, and “Provention” in Guatemala

    Directory of Open Access Journals (Sweden)

    Colette G. Mazzucelli

    2015-10-01

    Full Text Available This article deliberately examines the search for truth after decades of conflict in Guatemala. Excavations of mass gravesites and the painstaking exhumation processes carried out by professional forensic anthropology teams continue to allow families to locate lost relatives—reclaiming truth and supporting calls for justice. For Guatemalans, the search for truth now transcends national borders, especially among migrant communities in the United States. The family remains the central unit through which the work of Guatemalan forensic anthropologists is undertaken. In an effort to engender deeper insights about these exhumation processes from a social science perspective, this analysis promotes the use of specific “tools” in Guatemalan forensic anthropology investigations. The first is an exhumations concept map, which yields important questions meant to stimulate meaningful analysis. The second, Story Maps, is a technology application with the potential to mediate digital access to the emerging Guatemalan translocal space. The research in this analysis suggests that these “tools” strengthen Burton’s notion of “provention” in Guatemala.

    2018-03-01

    The notion of truth and its determination in legal proceedings is contingent on the cultural setting in which a claim is argued or disputed. Recent years have demonstrated a dramatic shift in the public dialogue concerning sexual harassment. This shift reflects changing cultural mores and standards in the workplace and society as a whole, particularly with respect to the validity of women's voices. The subjective reality experienced by victims of sexual harassment is inherently tied to the legal system's treatment of women throughout history. In determinations of truth, our understanding of which information and perspectives are relevant, and our expectations regarding the credibility of complainants and the accused, are undergoing a period of rapid change. The discourse surrounding the #MeToo movement suggests that the "reasonable-person" standard so often applied by courts is poorly suited to sexual-harassment litigation. As our understanding of what constitutes "severe," "pervasive," and "unwelcome" conduct continues to evolve, forensic psychiatrists must strive to uphold the values of respect for persons in the search for the truth. © 2018 American Academy of Psychiatry and the Law.

    Full Text Available As important as the need for authentic leadership in the fields of politics, economy and education in Africa may be, the continent is also in dire need of leadership for reconciliation. Against the backdrop of the South African Truth and Reconciliation Commission (TRC, the author � who served on the Commission � discusses five characteristics of leaders for reconciliation. Leaders need to be: leaders with a clear understanding of the issues at stake; leaders with respect for the truth; leaders with a sense of justice; leaders with a comprehension of the dynamics of forgiveness; and leaders with a firm commitment. The insights and experiences of both the chairperson of the TRC, Desmond Tutu, and the deputy chair, Alex Boraine, form the backbone of the article.

    2016-01-01

    NASA's Mars Exploration Rover Opportunity has been exploring approximately 22 km diameter Endeavour crater since 2011. Its rim segments predate the Hesperian-age Burns formation and expose Noachian-age material, which is associated with orbital Fe3+-Mg-rich clay mineral observations [1,2]. Moving to an orders of magnitude smaller instrumental field of view on the ground, the clay minerals were challenging to pinpoint on the basis of geochemical data because they appear to be the result of near-isochemical weathering of the local bedrock [3,4]. However, the APXS revealed a more complex mineral story as fracture fills and so-called red zones appear to contain more Al-rich clay minerals [5,6], which had not been observed from orbit. These observations are important to constrain clay mineral formation processes. More detail will be added as Opportunity is heading into her 10th extended mission, during which she will investigate Noachian bedrock that predates Endeavour crater, study sedimentary rocks inside Endeavour crater, and explore a fluid-carved gully. ESA's ExoMars rover will land on Noachian-age Oxia Planum where abundant Fe3+-Mg-rich clay minerals have been observed from orbit, but the story will undoubtedly become more complex once seen from the ground.

    The retrieval of radioactive wastes and the closure of the repository Asse II is a very complex project: not only with respect to technical aspects but also with respect to public information. The information brochure no 29 edited by the Bundesamt fuer Strahlenschutz BfS is dealing with the rather philosophic questions knowledge and truth. The German expert on constitutional law Peter Bull answered to the question whether subjectively assumed health hazards could inhibit a reasonable solution: it has to be expected from the public to bear inconvenient truth. Clarification is necessary instead of wrong populism and suppression of obnoxious findings.

    Methods of performing signature extension, using LANDSAT-1 data, are explored. The emphasis is on improving the performance and cost-effectiveness of large area wheat surveys. Two methods were developed: ASC, and MASC. Two methods, Ratio, and RADIFF, previously used with aircraft data were adapted to and tested on LANDSAT-1 data. An investigation into the sources and nature of between scene data variations was included. Initial investigations into the selection of training fields without in situ ground truth were undertaken.

    Full Text Available The paper describes the assessment of the vegetation and the land use systems of the Malinda Wetland in the Usambara Mountains in Tanzania with the parachute UAS (unmanned aerial system SUSI 62. The area of investigation was around 8 km2. In two campaigns, one in the wet season and one in the dry season, approximately 2600 aerial photos of the wetland were taken using the parachute UAS SUSI 62; of these images, ortho-photos with a spatial resolution of 20 cm x 20 cm, were computed with an advanced block bundle approach. The block bundles were geo-referenced using control points taken with differential GPS. As well a digital surface model (DSM of the wetland was created out of the UAS photos. Using the ortho-photos it is possible to assess the different land use systems; the differences in the phenology of the vegetation between wet and dry season can be investigated. In addition, the regionalisation of bio mass samples on smaller test plots was possible. The ortho-photos and the DSM derived from the UAS proved to be a valuable ground truth for the interpretation of Terra-SAR X images. The campaigns demonstrated that SUSI 62 was a suitable, robust tool to obtain the valuable information under harsh conditions.

Analüüsin armastusekujutust kirjandusteostes Alain Badiou armastusmudelite abil ning lisan juurde „omailma-armastuse mudeli“, mis rõhutab armastatu lahutamatust teda ümbritsevast ruumist: armastus ei hõlma vaid armastatut kui kindlalt piiritletud kehalist üksust, vaid ka seda, kuidas armastatu suhestub teda ümbritseva ruumiga ja inimestega.   This article presents and analyses Western cultural models for speaking and thinking about love. According to Michel Foucault, each society establishes its regimes of truth: certain types of discourses are approved as truthful while others are declared unreliable. Each society includes mechanisms of control, which distinguish true statements from false, and assign some people (but not others the authority to judge the true and the false, the acceptable and the unacceptable. Regimes of truth also establish paradigms for judging the truthfulness of love: according to the romantic regime, for example, love is something ephemeral, ungraspable and immeasurable, it transgresses established boundaries and norms; according to the pragmatic regime, by contrast, love can be expressed in economic terms and thus measured: a precious gift expresses commitment (else it would be a waste of money. There may be no common ground for one regime to concede legitimacy to a value asserted by a competing regime. In the view of the romantic regime, for example, the pragmatic regime might be judged as cynical and failing to grasp the essence of love – such weighing of feelings belongs to modern regimes of truth. Both romantic and pragmatic regimes of truth belong to the larger field of cultural imaginaries. Regimes of truth order and systematize the sphere of cultural

The following paper will discuss the method of data acquisition, post-processing, and analysis of the results. The final conclusions of the survey show a continuation of several key walls to the east, a valuable sub-surface tracing of the limestone bedrock, and the limit to which the archaeological material is present spatially in Area B to the north. These results play a major role in determining where to focus excavation efforts in the 2014 excavation season. This unique collaboration with the archaeological team and ongoing opportunity for archaeological ground-truthing will be documented and published as the site develops. As there is a limited presence of such data within the corpus of published archaeogeophysical research, we look forward to further investigations at the site in the coming years.

  20. Performance Assessment Monitoring Plan for the Hanford Site Low-Level Burial Grounds

    International Nuclear Information System (INIS)

    2006-01-01

    The U.S. Department of Energy Order 435.1, Radioactive Waste Management, requires a disposal authorization statement authorizing operation (or continued operation) for low-level waste disposal facilities. In fulfillment of these requirements, a disposal authorization statement was issued on October 25, 1999, authorizing the Hanford Site to transfer, receive, possess, and dispose of low-level radioactive waste at the 200 East Area burial grounds and the 200 West Area burial grounds. One of the conditions is that monitoring plans for the 200 East Area and 200 West Area low-level burial grounds be written and approved by the Richland Operations Office. As a result of a record of decision for the Hanford Site Solid Waste Program and acceptance of the Hanford Site Solid Waste Environmental Impact Statement, the use of the low-level burial ground (LLBG) as a disposal facility for low-level and mixed low-level wastes has been restricted to lined trenches and the Navy reactor-compartment trench only. Hence, as of July 2004, only the two lined trenches in burial ground 218-W-5 (trenches 31 and 34, see Appendix A) and the Navy reactor-compartment trench in burial ground 218 E 12B (trench 94) are allowed to receive waste. When the two lined trenches are filled, the LLBG will cease to operate except for reactor compartment disposal at trench 94. Remaining operational lifetime of the LLBG is dependent on waste volume disposal rates. Existing programs for air sampling and analyses and subsidence monitoring are currently adequate for performance assessment at the LLBG. The waste disposal authorization for the Hanford Site is based (in part) on the post-closure performance assessments for the LLBG. In order to maintain a useful link between operational monitoring (e.g., Resource Conservation and Recovery Act [RCRA], Comprehensive Environmental Response, Compensation, and Liability Act, and State Waste Discharge Permits), constituents, monitoring frequencies, and boundaries require

    Science.gov (United States)

    Byk, Christian

    2007-09-01

    Autonomy has become in many countries a key concept in the patient-physician relationship, leaving the old paternalistic medical attitude out of the realm of common good clinical practice. Consequently, the validity of the informed consent procedure which is related to any medical intervention, should imply that the information given is true. Raising the question as such obliges us to consider the truth not for itself but in regard to the validity of the consent to a medical intervention. Although a clinical approach reveals that loyalty should guide the patient-physician relationship, there are still some situations in which informed consent and truth telling may be controversial: in some circumstances, the physician should or may not tell the truth, in others he can simply forget to tell.

    Cryogenic propellant loading operations with their associated flight and ground systems are some of the most complex, critical activities in launch operations. Consequently, these systems and operations account for a sizeable portion of the life cycle costs of any launch program. NASA operations for handling cryogens in ground support equipment have not changed substantially in 50 years, despite advances in cryogenics, system health management and command and control technologies. This project was developed to mature, integrate and demonstrate advancement in the current state of the art in these areas using two distinct integrated ground operations demonstration units (GODU): GODU Integrated Refrigeration and Storage (IRAS) and GODU Autonomous Control

    As directed by the U.S. Department of Energy (DOE), Richland Operations Office (DOE-RL), Fluor Hanford, Inc. will implement the requirements of DOE Order 435.1, Radioactive Waste Management, as the requirements relate to the continued operation of the low-level waste disposal facilities on the Hanford Site. DOE Order 435.1 requires a disposal authorization statement authorizing operation (or continued operation) of a low-level waste disposal facility. The objective of this Order is to ensure that all DOE radioactive waste is managed in a manner that protects the environment and personnel and public health and safety. The manual (DOE Order 435.1 Manual) implementing the Order states that a disposal authorization statement shall be issued based on a review of the facility's performance assessment and composite analysis or appropriate Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980 documentation. The disposal authorization shall specify the limits and conditions on construction, design, operations, and closure of the low-level waste facility. Failure to obtain a disposal authorization statement shall result in shutdown of an operational disposal facility. In fulfillment of the requirements of DOE Order 435.1, a disposal authorization statement was issued on October 25, 1999, authorizing the Hanford Site to transfer, receive, possess, and dispose of low-level radioactive waste at the 200 East Area and the 200 West Area Low-Level Burial Grounds. The disposal authorization statement constitutes approval of the performance assessment and composite analysis, authorizes operation of the facility, and includes conditions that the disposal facility must meet. One of the conditions is that monitoring plans for the 200 East Area and 200 West Area Low-Level Burial Grounds be written and approved by the DOE-RL. The monitoring plan is to be updated and implemented within 1 year following issuance of the disposal authorization statement to

    2009-01-01

    Full Text Available During the last twenty years, we have assisted to a growing interest in the detection of verbal cues under deception. In this context, we focused our attention on the truth vs. deception topic in adults. In particular, we were interested in discrepant findings concerning some verbal indicators. The aim of the present study was to investigate whether different experimental designs may yield different results regarding the presence or absence of CBCA criteria. Forty participants were shown a video of a robbery and were asked to give a truthful and a deceitful statement of the criminal event. The participants’ performances were recorded in order to analyze content of the reports. Results showed more changes in verbal behaviour under within-subjects design compared to between-subjects one, though the presence/absence of some criteria was the same across the two statistical procedures. The different results yielded by between- and within-subjects analyses can provide some hints as regards the discrepancy in deception literature on verbal cues. Implications for applied settings are discussed.

  11. Truth comes into play: Adorno, Kant and Aesthetics

    Directory of Open Access Journals (Sweden)

    Berta M. Pérez

    2009-10-01

    Full Text Available This paper departs from the verification of the centrality that, in Adorno’s recognition of the aesthetic field, the rehabilitation of its bond to knowledge and truth has. Adorno’s criticism to the Kantian aesthetic theory is, this way, reconstructed starting from his dismissal of the separation, established by Kant, between the aesthetic and the epistemological fields. This criticism, which accuses the Kantian aesthetics of subjectivism, is finally taken back to Adorno’s dissatisfaction regarding the transcendental approach, for not being dialectic. At this point, the need of determining the specificity of his own understanding of the aesthetic and dialectics becomes apparent. Surprisingly it is then discovered an unexpected proximity between his position and the one represented by the Kantian aesthetics itself, a proximity that let recognize in the latter some features which go beyond the limits of the Critical System towards the Adornian approach. But this proximity proves also the immanence and legitimacy of the (ambiguous Adornian criticism to Kant, and, as a result of this, the unsatisfactory quality of the Kantian determination of knowledge and truth.

  13. The structure of contraceptive education and instruction within nurse led family planning clinics: a grounded theory study.

    Science.gov (United States)

    Hayter, Mark

    2009-09-01

    This study aimed to explore and analyse how nurses instruct women in contraceptive use during consultations in family planning clinics to produce a grounded theory of contraceptive education. Nurses play a key role in instructing women how to use contraception in family planning clinic consultations. These one-to-one situations are encounters where women are taught how to use contraceptive methods effectively. However, very little is known about the nature of these consultations. A qualitative study using a grounded theory approach was used. Three linked 'core categories' emerged from the data analysis. Firstly, women are educated about their body and how it responds to contraception: 'reproductive education'. This core category is closely linked to 'surveillance' where women are taught to monitor their reproductive health and to 'contraceptive regimen' where women are instructed in techniques to successfully use a contraceptive method. Together these three core categories present a grounded theory of 'contraceptive education'. Nursing practice in this important area of women's health care is complex and requires skilled practitioners. This study presents unique empirical data into how nurses conduct one-to-one consultations with women - providing a novel insight into how contraception is explained in clinical situations. Key issues for practice from the data were the lack of a balance when discussing side effects, the rigidity of some instructions and the lack of recognition of risk from sexually transmitted infection. Nurses working in sexual health need to ensure that women understand the often complex instructions they provide and that rigid instruction be occasionally amended to enable some flexibility. The manner in which side-effects are discussed should also be balanced. Nurses need to address the risk of sexually transmitted infections more substantially in contraceptive discussions.

    2004-01-01

    Ground water play a major role in national economy and sustenance of life and environment. Prevalent water crisis in India includes falling water table, water quality deterioration, water logging and salinity. Keeping in view the increasing thrust on groundwater resources and the present scenario of availability vis-a vis demand there is a need to reorient our approach to ground water management. The various ground water management options require proper understanding of ground water flow system. Isotopes are increasingly being applied in hydrogeological investigations as a supplementary tool for assessment of aquifer flow and transport characteristics. Isotope techniques coupled with conventional hydrogeological and hydrochemical methods can bring in greater accuracy in the conceptualization of hydrogeological control mechanism. The use of isotope techniques in following areas can certainly be of immense help in implementing various ground water management options in an efficient manner. viz.Interaction between the surface water - groundwater systems to plan conjunctive use of surface and ground water. Establishing hydraulic interconnections between the aquifers in a multi aquifer system. Depth of circulation of water and dating of ground water. Demarcating ground water recharge and discharge areas. Plan ground water development in coastal aquifers to avoid sea water ingress. Development of flood plain aquifer. (author)

    Proposed by professionals of various disciplines, this book is considered as the bible of climate sceptics. It proposes a synthesis of arguments which deny prevailing views in the domain of climate. The authors show how, since fifteen years, reality has systematically denied projections made by the IPCC and its numerous political relays and media coverage. A first objective is therefore to unlatch the debate on the climate issue in front of a systematic practice of monopolization of truth at the expense of an authentic scientific approach, and to restore a democratic debate. A second objective is to put into question again the IPCC scientific character, scientific views which are at the heart of the last report published by the IPCC, and the political, media and economic reception of IPCC reports

  2. Interim Action Proposed Plan for the old radioactive waste burial ground (643-E)

    1995-12-01

    This Interim Action Proposed (IAPP) is issued by the U.S. Department of Energy (DOE), which functions as the lead agency for SRS remedial activities, and with concurrence by the U.S. Environmental Protection Agency (EPA) and the South Carolina Department of Health and Environmental Control (SCDHEC). The purpose of this IAPP is to describe the preferred interim remedial action for addressing the Old Radioactive Waste Burial Ground (ORWBG) unit located in the Burial Ground Complex (BGC) at the Savannah River Site (SRS) in Aiken, South Carolina. On December 21, 1989, SRS was included on the National Priorities List (NPL). In accordance with Section 120 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), DOE has negotiated a Federal Facility Agreement (FFA, 1993) with EPA and SCDHEC to coordinate remedial activities at SRS. Public participation requirements are listed in Sections 113 and 117 of CERCLA. These requirements include establishment of an Administrative Record File that documents the selection of remedial alternatives and allows for review and comment by the public regarding those alternatives. The SRS Public Involvement Plan (PIP) (DOE, 1994) is designed to facilitate public involvement in the decision-making process for permitting closure, and the selection of remedial alternatives. Section 117(a) of CERCLA, 1980, as amended, requires publication of a notice of any proposed remedial action

  4. SUSTAINABLE DEVELOPMENT – HUMAN DEVELOPMENT CONNECTIONS IN THE POST-TRUTH ERA

    2017-08-01

    Full Text Available Following the distancing of current policy from economic rigors and ethical demands aimed at redistribution of wealth, modern societies are parasitized by post-truth of actual facts. It distorts the shape and content of general interest data, for example political distortion of scientific evidence proving anthropogenic climate change. Under these circumstances, the question "to what extent economist’s truth stating what you cannot measure you cannot manage is sustained?" becomes absolutely legitimate. Regarding sustainable development management, monitoring the degree of achievement of Sustainable Development Goals is no longer sufficient to track progress in this area. Therefore, experts propose to introduce as much as possible qualitative data which, combined with quantitative data, will enhance their relevance and make them harder to be diverted for political purposes. This paper follows this direction, trying to prove that protection of data’s real meaning can be achieved by systemic analysis of all data originating from monitoring certain processes, which can be aggregated, with applicability in sustainable development. Thus, analyzing together data on sustainable development and those that indicates the state of human development emphasizes on one hand, the intrinsic link between these concepts and, on the other, maintain the sense of sustainability even in the post-truth era.

  5. Constructing the truth: from 'confusion of tongues' to 'constructions in analysis'.

    The author hypothesizes that the papers Freud wrote in the period 1934-9 constitute a final turning point in his work resulting from an attempt to work through, by means of self-analysis, early traumatic elements reactivated by the conditions of his life in the 1930s. The author emphasizes that the ups and downs of Freud's relationship with Sándor Ferenczi and the mourning which followed his death in 1933 played an important role in this traumatic situation. He suggests that through these last works, Freud pursued a posthumous dialogue with Ferenczi. This working through led Freud, in Moses and monotheism, to an ultimate revision of his theory of trauma, a revision which the author examines in full, in the light of the works of the Egyptologist, Jan Assmann. A new analytical paradigm emerges: that of constructions in analysis developed in the article of the same name. The activity of construction appears as an alternative to the mutual analysis proposed by Ferenczi and is closely bound up with the notion of historical truth. In psychoanalysis, it would mean constructing a historical truth whose anchoring in the material truth of the past is essential, though it should not be confused with it.

    Two competing approaches to policy analysis are distinguished: a credibility approach, and a truth approach. According to the credibility approach, the policy analyst's role is to search for plausible argument rather than truth. Each approach has pragmatic tradeoffs in fulfilling the goal of providing usable knowledge to decision makers. (TJH)

    We analyze variations in environmental parameters and regolith properties along Curiosity's track to determine the possible causes of an abrupt change in the thermal properties of the ground and the atmosphere observed around Sol 120, as the rover transitioned from an area of sandy soil (Rocknest) to an area of fractured bedrock terrain (Yellowknife). Curiosity is instrumented with the Rover Environmental Monitoring Station (REMS) and the Dynamic Albedo of Neutrons (DAN) sensors to measure the air temperature, the ground temperature, and the hydrogen content of the shallow subsurface along Curiosity's track. Analysis of the REMS data is used to estimate the regolith's heat budget. This analysis suggests that the abrupt decrease in the ground and atmosphere temperature and the difference between ground and air temperatures observed around Sol 120 is likely caused by an increase in the soil thermal inertia. The changes in thermal inertia have been known for some time so confirming this by the REMS package provides ground truthing. A new unexpected finding is that the regolith water content, as indicated by DAN's detection of hydrogen content, is higher in the Yellowknife soil. Another interesting finding at this site are the holes and other signs of recent geological activity in the area of fractured terrain that may reflect large volumetric variations and facilitate gas exchange between the ground and atmosphere. Near-surface volumetric changes in soil and bedrock could reflect changes in the volume of subsurface H2O, or in the partitioning of H2O among its three phases. Volume increases could also result from salt crystal growth in rock pores and soil pores associated with the adsorption of water vapor. Crystallization in pores is a significant weathering process on Earth; it could well be active on Mars. Salts also inhibits the exchange of moisture between the ground and the atmosphere, and cements the soils of arid places such as in the McMurdo Dry Valleys in

  12. When is Deceptive Message Production More Effortful than Truth-Telling? A Baker's Dozen of Moderators.

    Science.gov (United States)

    Burgoon, Judee K

    2015-01-01

    Deception is thought to be more effortful than telling the truth. Empirical evidence from many quarters supports this general proposition. However, there are many factors that qualify and even reverse this pattern. Guided by a communication perspective, I present a baker's dozen of moderators that may alter the degree of cognitive difficulty associated with producing deceptive messages. Among sender-related factors are memory processes, motivation, incentives, and consequences. Lying increases activation of a network of brain regions related to executive memory, suppression of unwanted behaviors, and task switching that is not observed with truth-telling. High motivation coupled with strong incentives or the risk of adverse consequences also prompts more cognitive exertion-for truth-tellers and deceivers alike-to appear credible, with associated effects on performance and message production effort, depending on the magnitude of effort, communicator skill, and experience. Factors related to message and communication context include discourse genre, type of prevarication, expected response length, communication medium, preparation, and recency of target event/issue. These factors can attenuate the degree of cognitive taxation on senders so that truth-telling and deceiving are similarly effortful. Factors related to the interpersonal relationship among interlocutors include whether sender and receiver are cooperative or adversarial and how well-acquainted they are with one another. A final consideration is whether the unit of analysis is the utterance, turn at talk, episode, entire interaction, or series of interactions. Taking these factors into account should produce a more nuanced answer to the question of when deception is more difficult than truth-telling.

    Fake news and post-truth pronouncements are increasingly common, and are unfortunately also progressively being applied to the sciences, including the medical sciences. This editorial briefly reviews this unsavoury trend and highlights recent debunking of fake truths in early human development. Science is arguably the last metanarrative with any significant cachet in the postmodern period. We, as scientists, must strive to ensure that our work is transparent and of the highest possible standard so as to continue to uphold science's integrity and probity. Copyright © 2017 Elsevier B.V.

  14. INFORMATION USE ABOUT THE LEVEL OF AIRCRAFT FLIGHTS GROUND PROVISION TO PLAN AIR TRAFFIC

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The given article considers the task of building up the best aircraft route on the basis of information about the level of flight ground provision. Disadvantages of traditional radar surveillance facilities are given. Four types of Russian Feder- ation aerospace depending on the level of ground radio flight provision are considered. Relevance of selecting an aircraft route from the view of necessity to plan aerospace is substantiated. The formula to calculate probabilities of obtaining not correct aircraft navigation data is given. The analysis of errors arising while building up the aircraft route linked with both operational navigation and communication equipment faults as well as with a human factor is carried out. Formulas of wrong route selecting probability when an aircraft track changes or is maintained are suggested. A generalized weighted index of losses on the basis of various factors affecting an aircraft track change is introduced. Importance of these factors are considered. A rule of aircraft transition to the next route point is formulated. The conclusion is made which route is the most rational in case of following the rule of route selecting at every flight stage. Practical recommendations which can be used to solve conflict between aircraft cruising under the given rule are suggested.

    Long, Terry; Taubenheim, Ann; Wayman, Jennifer; Temple, Sarah; Ruoff, Beth

    2008-03-01

    In September 2002, the National Heart, Lung, and Blood Institute launched The Heart Truth, the first federally-sponsored national campaign aimed at increasing awareness among women about their risk of heart disease. A traditional social marketing approach, including an extensive formative research phase, was used to plan, implement, and evaluate the campaign. With the creation of the Red Dress as the national symbol for women and heart disease awareness, the campaign integrated a branding strategy into its social marketing framework. The aim was to develop and promote a women's heart disease brand that would create a strong emotional connection with women. The Red Dress brand has had a powerful appeal to a wide diversity of women and has given momentum to the campaign's three-part implementation strategy of partnership development, media relations, and community action. In addition to generating its own substantial programming, The Heart Truth became a catalyst for a host of other national and local educational initiatives, both large and small. By the campaign's fifth anniversary, surveys showed that women were increasingly aware of heart disease as their leading cause of death and that the rise in awareness was associated with increased action to reduce heart disease risk.

    1992-11-01

    The Bear Creek Burial Grounds (BCBG) are located on the southwest flank of Pine Ridge ∼1.5 miles west of the Oak Ridge Y-12 Plant in Bear Creek Valley. This facility consists of several contiguous disposal sites identified as Burial Grounds A, B, C, and D. Each burial site consists of a series of trenches used for disposal of solid wastes and, in some cases, liquid wastes. Initially, the RCRA Closure/Postclosure plan for the BCBG was intended to apply to A Area, C-West, B Area, and the walk-in pits for BCBG. However, a plan was provided to include the B Area in the walk-in pits so that both areas cold be closed under one cap. The closure plan for B Area and the walk-in pits is presented in this document. The actual quantity and identity of materials is uncertain. The largest volume of material disposed in BCBG consists of uranium-contaminated industrial trash (paper, wood, steel, glass, and rubble)

    2017-01-01

    Truth-telling toward terminally ill patients is a challenging ethical issue in healthcare practice. However, there are no existing ethical guidelines or frameworks provided for Chinese nurses in relation to decision-making on truth-telling of terminal illness and the role of nurses thus is not explicit when encountering this issue. The intention of this paper is to provide ethical guidelines or strategies with regards to decision-making on truth-telling of terminal illness for Chinese nurses. This paper initially present a case scenario and then critically discuss the ethical issue in association with ethical principles and philosophical theories. Instead of focusing on attitudes toward truth disclosure, it aims to provide strategies regarding this issue for nurses. It highlights and discusses some of the relevant ethical assumptions around the perceived role of nurses in healthcare settings by focusing on nursing ethical virtues, nursing codes of ethics, and philosophical perspectives. And Confucian culture is discussed to explicate that deontology does not consider family-oriented care in China. Treating each family individually to explore the family's beliefs and values on this issue is essential in healthcare practice and nurses should tailor their own approach to individual needs regarding truth-telling in different situations. Moreover, the Chinese Code of Ethics should be modified to be more specific and applicable. Finally, a narrative ethics approach should be applied and teamwork between nurses, physicians and families should be established to support cancer patients and to ensure their autonomy and hope. Ethical considerations: This paper was approved by the Ethics Committee of The Second Affiliated Hospital of Guangzhou Medical University. The authors have obtained consent to use the case study and it has been anonymised to preserve the patient's confidentiality.

    Md. Istiaque Hasan

    2014-01-01

    Full Text Available The reinforced concrete cast in place four span deck of a concrete bridge near Roanoke, Texas, was recently completed. Due to possible construction errors, it was suspected that the concrete covers in the deck did not conform to drawings and specifications. A full scale non-destructive evaluation of the concrete covers was carried out using ground penetrating radar (GPR equipment. Cover values were determined from the radargram generated from the scan. The estimated covers were plotted on contour maps. Migration data can substitute the drilling based ground truth data without compromising the concrete cover estimations, except for areas with very high cover values. Areas with high water content may result in inaccurate concrete dielectric constants. Based on the results, significant retrofitting of the bridge deck, such as additional overlay, was recommended.

    Full Text Available Publicly available benchmark data and metric evaluation approaches have been instrumental in enabling research to advance state of the art methods for remote sensing applications in urban 3D modeling. Most publicly available benchmark datasets have consisted of high resolution airborne imagery and lidar suitable for 3D modeling on a relatively modest scale. To enable research in larger scale 3D mapping, we have recently released a public benchmark dataset with multi-view commercial satellite imagery and metrics to compare 3D point clouds with lidar ground truth. We now define a more complete metric evaluation pipeline developed as publicly available open source software to assess semantically labeled 3D models of complex urban scenes derived from multi-view commercial satellite imagery. Evaluation metrics in our pipeline include horizontal and vertical accuracy and completeness, volumetric completeness and correctness, perceptual quality, and model simplicity. Sources of ground truth include airborne lidar and overhead imagery, and we demonstrate a semi-automated process for producing accurate ground truth shape files to characterize building footprints. We validate our current metric evaluation pipeline using 3D models produced using open source multi-view stereo methods. Data and software is made publicly available to enable further research and planned benchmarking activities.

    Directory of Open Access Journals (Sweden)

    A G Vethuizen

    2014-12-01

    Full Text Available The aim of this article is to propose some principles and practices for truth-seeking during research into violent conflict. To achieve this aim, an argument is deployed by analysing the theoretical concepts “truth”, “myth” and “oral culture” as sources of knowledge. This conceptual analysis precedes a discussion on community-based participatory research (CBPR as a research methodology to access the knowledge of lived experiences embedded in the oral culture of the San community of Platfontein, near Kimberley, South Africa. It was found that CBPR contains good practices to use in research to judge the probable truth about disputes. The CBPR process is ideal for determining the accuracy of data in the context of a specific culture, considering the norms, spiritual influences and personal considerations of knowledge-holders that accompany a unique cosmology. A variety and equity of worldviews and perspectives of what happened during violent conflict successfully challenges hegemonic power relationships, paradigms and narratives, ultimately leading to informed judgements of what is probably true about a conflict. CBPR with the San of Platfontein revealed principles that can be used as guidelines for researching disputes where oral culture is involved.

  8. Truth and Fibble-Fable in Renaissance Satire

    Directory of Open Access Journals (Sweden)

    Branko Madžarevič

    2011-12-01

    Full Text Available Throughout the years of my close involvement with wor(lds’ transactions, as a translator, in the triangle of the Renaissance doctors Rabelais, Montaigne, and, yes, Louis-Ferdinand Céline, the French author of the novel Journey to the End of Night (1932, their views on satire can be considered from a rather unconventional angle. By means of an imaginary morbid epistolary medical council, the impromptu introduction tries to entangle this peculiar trio in a freewheeling alliance, leading to the assumption that every translation defies the interpretational ambiguities of the utopian Thelema motto “Do as you will”. In the satirical context of all source and target faces, it is always acting on the verge of the paradoxical encomium, the hypothetical pasticcio, and obscurantist reversals of the original text. Of course, the issue at stake here is one of the convolutions of Erasmus’ Praise of Folly, Rabelais’ utopian Thelema Abbey, and the German Epistles of Obscure Men in pathetically wretched Latin. This paper deals with Renaissance and humanist satire, focusing on Rabelais’ five books of Gargantua and Pantagruel (1532–1564 and the interplay between the ideas of truth, truthfulness, and seriousness. In addition, the paper deals with how the Renaissance spirit of this satirical contemporary and ally of ours challenges the issue of verbal boundaries and the materiality of language.

  11. Good things don't come easy (to mind): explaining framing effects in judgments of truth.

    Science.gov (United States)

    Hilbig, Benjamin E

    2012-01-01

    Recently, the general phenomenon of a positive-negative-asymmetry was extended to judgments of truth. That is, negatively framed statements were shown to receive substantially higher truth ratings than formally equivalent statements framed positively. However, the cognitive mechanisms underlying this effect are unknown, so far. In the current work, two potential accounts are introduced and tested against each other in three experiments: On the one hand, negative framing may induce increased elaboration and thereby persuasion. Alternatively, negative framing could yield faster retrieval or generation of evidence and thus influence subjective veracity via experiential fluency. Two experiments drawing on response latencies and one manipulating the delay between information acquisition and judgment provide support for the fluency-based account. Overall, results replicate and extend the negatively-biased framing effect in truth judgments and show that processing fluency may account for it. © 2011 Hogrefe Publishing

    A survey of wetlands on the Oak Ridge Reservation (ORR) was conducted in 1990. Wetlands occurring on ORR were identified using National Wetlands Inventory (NWI) maps and field surveys. More than 120 sites were visited and 90 wetlands were identified. Wetland types on ORR included emergent communities in shallow embayments on reservoirs, emergent and aquatic communities in ponds, forested wetland on low ground along major creeks, and wet meadows and marshes associated with streams and seeps. Vascular plant species occurring on sites visited were inventoried, and 57 species were added to the checklist of vascular plants on ORR. Three species listed as rare in Tennessee were discovered on ORR during the wetlands survey.

  16. When is deceptive message production more effortful than truth-telling? A baker’s dozen of moderators

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Deception is thought to be more effortful than telling the truth. Empirical evidence from many quarters supports this general proposition. However, there are many factors that qualify and even reverse this pattern. Guided by a communication perspective, I present a baker’s dozen of moderators that may alter the degree of cognitive difficulty associated with producing deceptive messages. Among sender-related factors are memory processes, motivation, incentives, and consequences. Lying increases activation of a network of brain regions related to executive memory, suppression of unwanted behaviors, and task switching that is not observed with truth-telling. High motivation coupled with strong incentives or the risk of adverse consequences also prompts more cognitive exertion--for truth-tellers and deceivers alike--to appear credible, with associated effects on performance and message production effort, depending on the magnitude of effort, communicator skill and experience. Factors related to message and communication context include discourse genre, type of prevarication, expected response length, communication medium, preparation, and recency of target event/issue. These factors can attenuate the degree of cognitive taxation on senders so that truth-telling and deceiving are similarly effortful. Factors related to the interpersonal relationship among interlocutors include whether sender and receiver are cooperative or adversarial and how well-acquainted they are with one another. A final consideration is whether the unit of analysis is the utterance, turn at talk, episode, entire interaction, or series of interactions. Taking these factors into account should produce a more nuanced answer to the question of when deception is more difficult than truth-telling.

  17. QCD-aware partonic jet clustering for truth-jet flavour labelling

    Energy Technology Data Exchange (ETDEWEB)

    Buckley, Andy; Pollard, Chris [University of Glasgow, School of Physics and Astronomy, Glasgow (United Kingdom)

    2016-02-15

    We present an algorithm for deriving partonic flavour labels to be applied to truth particle jets in Monte Carlo event simulations. The inputs to this approach are final pre-hadronisation partons, to remove dependence on unphysical details such as the order of matrix element calculation and shower generator frame recoil treatment. These are clustered using standard jet algorithms, modified to restrict the allowed pseudo-jet combinations to those in which tracked flavour labels are consistent with QCD and QED Feynman rules. The resulting algorithm is shown to be portable between the major families of shower generators, and largely insensitive to many possible systematic variations: it hence offers significant advantages over existing ad hoc labelling schemes. However, it is shown that contamination from multi-parton scattering simulations can disrupt the labelling results. Suggestions are made for further extension to incorporate more detailed QCD splitting function kinematics, robustness improvements, and potential uses for truth-level physics object definitions and tagging.

  19. Truth Seeded Reconstruction for Fast Simulation in the ATLAS Experiment

    CERN Document Server

    Jansky, Roland; Salzburger, Andreas

    The huge success of the ATLAS experiment for particle physics during Run 1 of the LHC would not have been possible without the production of vast amounts of simulated Monte Carlo data. However, the very detailed detector simulation is a highly CPU intensive task and thus resource shortages occurred. Motivated by this, great effort has been put into speeding up the simulation. As a result, other timeconsuming parts became visible. One of which is the track reconstruction. This thesis describes one potential solution to the CPU intensive reconstruction of simulated data: a newly designed truth seeded reconstruction. At its basics is the idea to skip the pattern recognition altogether, instead utilizing the available (truth) information from simulation to directly fit particle trajectories without searching for them. At the same time tracking effects of the standard reconstruction need to be emulated. This approach is validated thoroughly and no critical deviations of the results compared to the standard reconst...

  3. A Mixed Prediction Model of Ground Subsidence for Civil Infrastructures on Soft Ground

    Directory of Open Access Journals (Sweden)

    Kiyoshi Kobayashi

    2012-01-01

    Full Text Available The estimation of ground subsidence processes is an important subject for the asset management of civil infrastructures on soft ground, such as airport facilities. In the planning and design stage, there exist many uncertainties in geotechnical conditions, and it is impossible to estimate the ground subsidence process by deterministic methods. In this paper, the sets of sample paths designating ground subsidence processes are generated by use of a one-dimensional consolidation model incorporating inhomogeneous ground subsidence. Given the sample paths, the mixed subsidence model is presented to describe the probabilistic structure behind the sample paths. The mixed model can be updated by the Bayesian methods based upon the newly obtained monitoring data. Concretely speaking, in order to estimate the updating models, Markov Chain Monte Calro method, which is the frontier technique in Bayesian statistics, is applied. Through a case study, this paper discussed the applicability of the proposed method and illustrated its possible application and future works.

    Long, Terry; Taubenheim, Ann; Wayman, Jennifer; Temple, Sarah; Ruoff, Beth

    2008-01-01

    In September 2002, the National Heart, Lung, and Blood Institute launched The Heart Truth, the first federally-sponsored national campaign aimed at increasing awareness among women about their risk of heart disease. A traditional social marketing approach, including an extensive formative research phase, was used to plan, implement, and evaluate the campaign. With the creation of the Red Dress as the national symbol for women and heart disease awareness, the campaign integrated a branding strategy into its social marketing framework. The aim was to develop and promote a women's heart disease brand that would create a strong emotional connection with women. The Red Dress brand has had a powerful appeal to a wide diversity of women and has given momentum to the campaign's three-part implementation strategy of partnership development, media relations, and community action. In addition to generating its own substantial programming, The Heart Truth became a catalyst for a host of other national and local educational initiatives, both large and small. By the campaign's fifth anniversary, surveys showed that women were increasingly aware of heart disease as their leading cause of death and that the rise in awareness was associated with increased action to reduce heart disease risk.

    The national youth and young adult tobacco prevention mass media campaign, truth®, relaunched in 2014 with the goal of creating "the generation that ends smoking." The objective of this study was to assess whether the strategy of airing truth ads during popular, culturally relevant televised events was associated with higher ad and brand awareness and increases in social media engagement. Awareness of six truth advertisements that aired during popular television events and self-reported social media engagement were assessed via cross-sectional online surveys of youth and young adults aged 15-21 years. Social engagement was also measured using separate Twitter and YouTube metrics. Logistic regression models predicted self-reported social engagement and any ad awareness, and a negative binomial regression predicted the total social media engagement across digital platforms. The study found that viewing a popular televised event was associated with higher odds of ad awareness and social engagement. The results also indicate that levels of social media engagement for an event period are greater than for a nonevent period. The findings demonstrate that premiering advertisements during a popular, culturally relevant televised event is associated with higher awareness of truth ads and increased social engagement related to the campaign, controlling for variables that might also influence the response to campaign messages.

    Onboard Short Term Plan Viewer (OSTPV) is a computer program for electronic display of mission plans and timelines, both aboard the International Space Station (ISS) and in ISS ground control stations located in several countries. OSTPV was specifically designed both (1) for use within the limited ISS computing environment and (2) to be compatible with computers used in ground control stations. OSTPV supplants a prior system in which, aboard the ISS, timelines were printed on paper and incorporated into files that also contained other paper documents. Hence, the introduction of OSTPV has both reduced the consumption of resources and saved time in updating plans and timelines. OSTPV accepts, as input, the mission timeline output of a legacy, print-oriented, UNIX-based program called "Consolidated Planning System" and converts the timeline information for display in an interactive, dynamic, Windows Web-based graphical user interface that is used by both the ISS crew and ground control teams in real time. OSTPV enables the ISS crew to electronically indicate execution of timeline steps, launch electronic procedures, and efficiently report to ground control teams on the statuses of ISS activities, all by use of laptop computers aboard the ISS.

  12. Simple example of definitions of truth, validity, consistency, and completeness in quantum mechanics

    International Nuclear Information System (INIS)

    Benioff, P.

    1999-01-01

    Besides their use for efficient computation, quantum computers and quantum robots form a base for studying quantum systems that create valid physical theories using mathematics and physics. If quantum mechanics is universally applicable, then quantum mechanics must describe its own validation by these quantum systems. An essential part of this process is the development of a coherent theory of mathematics and quantum-mechanics together. It is expected that such a theory will include a coherent combination of mathematical logical concepts with quantum mechanics. That this might be possible is shown here by defining truth, validity, consistency, and completeness for a quantum-mechanical version of a simple (classical) expression enumeration machine described by Smullyan. Some of the expressions are chosen as sentences denoting the presence or absence of other expressions in the enumeration. Two of the sentences are self-referential. It is seen that, for an interpretation based on a Feynman path sum over expression paths, truth, consistency, and completeness for the quantum system have different properties than for the classical system. For instance, the truth of a sentence S is defined only on those paths containing S. It is undefined elsewhere. Also S and its negation can both be true provided they appear on separate paths. This satisfies the definition of consistency. The definitions of validity and completeness connect the dynamics of the system to the truth of the sentences. It is proved that validity implies consistency. It is seen that the requirements of validity and maximal completeness strongly restrict the allowable dynamics for the quantum system. Aspects of the existence of a valid, maximally complete dynamics are discussed. An exponentially efficient quantum computer is described that is also valid and complete for the set of sentences considered here. copyright 1999 The American Physical Society

  18. Truth or dare: expertise and risk governance

    International Nuclear Information System (INIS)

    Paterson, J.

    2002-01-01

    There is increasing evidence that the public is as concerned with the risks associated with technology as it is enthused by the opportunities that technology presents. Experts are increasingly referred to not so much for solutions to social problems per se, but paradoxically to problems attendant on technological solutions themselves. In these circumstances, there is an urgent need for the role of the expert to be clarified. While the public and political actors have essentially looked to experts for certainty in an uncertain world, this is precisely what scientific rationality cannot provide. The inherent modesty of science (exemplified, for example, by the need for falsifiability) must always be compromised at the point when a decision is made, when 'knowledge' becomes 'action'. There is accordingly a need to be clear about the status of scientific information or knowledge on the one hand, and the effect of the decision to act on the other - and hence the appropriate locus of responsibility. Analysing the process from expert advice through to political or economic decision can help to clarify the point at which misunderstanding arises, at which the inherently provisional truth of science is transformed into the effectively absolute truth implied by a decision to apply knowledge as technology. Recognizing that it is at this point that risks are run (as well as the opportunity for rewards created) may lead to greater clarity as to the respective roles. It may in turn offer some lessons as regards the design of risk governance arrangements and the place of experts in them. (author)

  19. Balancing truth-telling: relatives acting as translators for older adult cancer patients of Turkish or northwest African origin in Belgium.

    2017-09-01

    The first generation of Turkish and Northwest African immigrants in Belgium are ageing and at risk for developing cancer. Relatives play an important role and provide both emotional and practical care, including mental support and acting as a contact person and/or a translator for improving access to healthcare, as most patients and their spouses have only a limited command of the language. Although access to professional interpreters has shown to be the best guarantee for qualitative healthcare, oncology health providers working with relatives as interpreters is much more common than professional interpreters. The aim of this study was to provide insight into the process wherein relatives balance truth-telling in translating for an older family member diagnosed with cancer. This was a qualitative research study, with elements of constructivist grounded theory. Twenty-eight loosely structured interviews were conducted. Most relatives consider it their responsibility to contribute to a positive attitude of the patient. Relatives decided to what extent they inform the patient, based on several motives and embedded in their assessment of the patient's emotional strength, understanding and need to be informed. What they decide influences the way they act as a translator and/or a contact person between the patient and health professional(s). Some considered it best to omit medical information while others considered it best to inform the patient fully. The results emphasise the importance for healthcare providers to take into account the complexity and unpredictable character of the process of balancing truth-telling when family members translate for their ill older relative. © 2016 John Wiley & Sons Ltd.

  20. Therapeutic privilege: between the ethics of lying and the practice of truth.

    Science.gov (United States)

    Richard, Claude; Lajeunesse, Yvette; Lussier, Marie-Thérèse

    2010-06-01

    The 'right to the truth' involves disclosing all the pertinent facts to a patient so that an informed decision can be made. However, this concept of a 'right to the truth' entails certain ambiguities, especially since it is difficult to apply the concept in medical practice based mainly on current evidence-based data that are probabilistic in nature. Furthermore, in some situations, the doctor is confronted with a moral dilemma, caught between the necessity to inform the patient (principle of autonomy) and the desire to ensure the patient's well-being by minimising suffering (principle of beneficence). To comply with the principle of beneficence as well as the principle of non-maleficence 'to do no harm', the doctor may then feel obliged to turn to 'therapeutic privilege', using lies or deception to preserve the patient's hope, and psychological and moral integrity, as well as his self-image and dignity. There is no easy answer to such a moral dilemma. This article will propose a process that can fit into reflective practice, allowing the doctor to decide if the use of therapeutic privilege is justified when he is faced with these kinds of conflicting circumstances. We will present the conflict arising in practice in the context of the various theoretical orientations in ethics, and then we will suggest an approach for a 'practice of truth'. Last, we will situate this reflective method in the broader clinical context of medical practice viewed as a dialogic process.

    Barrow, Wylie C.; Baldwin, Michael J.; Randall, Lori A.; Pitre, John; Dudley, Kyle J.

    2013-01-01

    This project was initiated to assess migrating and wintering bird use of lands enrolled in the Natural Resources Conservation Service’s (NRCS) Migratory Bird Habitat Initiative (MBHI). The MBHI program was developed in response to the Deepwater Horizon oil spill in 2010, with the goal of improving/creating habitat for waterbirds affected by the spill. In collaboration with the University of Delaware (UDEL), we used weather surveillance radar data (Sieges 2014), portable marine radar data, thermal infrared images, and visual observations to assess bird use of MBHI easements. Migrating and wintering birds routinely make synchronous flights near dusk (e.g., departure during migration, feeding flights during winter). Weather radars readily detect birds at the onset of these flights and have proven to be useful remote sensing tools for assessing bird-habitat relations during migration and determining the response of wintering waterfowl to wetland restoration (e.g., Wetlands Reserve Program lands). However, ground-truthing is required to identify radar echoes to species or species group. We designed a field study to ground-truth a larger-scale, weather radar assessment of bird use of MBHI sites in southwest Louisiana. We examined seasonal bird use of MBHI fields in fall, winter, and spring of 2011-2012. To assess diurnal use, we conducted total area surveys of MBHI sites in the afternoon, collecting data on bird species composition, abundance, behavior, and habitat use. In the evenings, we quantified bird activity at the MBHI easements and described flight behavior (i.e., birds landing in, departing from, circling, or flying over the MBHI tract). Our field sampling captured the onset of evening flights and spanned the period of collection of the weather radar data analyzed. Pre- and post-dusk surveys were conducted using a portable radar system and a thermal infrared camera. Landbirds, shorebirds, and wading birds were commonly found on MBHI fields during diurnal

    While medical ethics place a high value on providing truthful information to patients, disclosure practices are far from being the norm in many countries. Transmitting bad news still remains a big problem that health care professionals face in their every day clinical practice. Through the review of relevant literature, an attempt to examine the trends in this issue worldwide will be made. Various electronic databases were searched by the authors and through systematic selection 51 scientific articles were identified that this literature review is based on. There are many parameters that lead to the concealment of truth. Factors related to doctors, patients and their close environment, still maintain a strong resistance against disclosure of diagnosis and prognosis in terminally ill patients, while cultural influences lead to different approaches in various countries. Withholding the truth is mainly based in the fear of causing despair to patients. However, fostering a spurious hope, hides the danger of its' total loss, while it can disturb patient-doctor relationship.

    In his excellent essay, 'Nudges in a post-truth world', Neil Levy argues that 'nudges to reason', or nudges which aim to make us more receptive to evidence, are morally permissible. A strong argument against the moral permissibility of nudging is that nudges fail to respect the autonomy of the individuals affected by them. Levy argues that nudges to reason do respect individual autonomy, such that the standard autonomy objection fails against nudges to reason. In this paper, I argue that Levy fails to show that nudges to reason respect individual autonomy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Patterned ground forms in periglacial zones from both expansion and contraction of permafrost by freeze-thaw and sub-freezing temperature changes and has been observed on both Earth and Mars from orbital and the surface at the Phoneix and Viking 2 landing sites. The Phoenix mission to Mars studied patterned ground in the vicinity of the spacecraft including the excavation of a trench revealing water permafrost beneath the surface. A study of patterned ground at the Haughton Impact structure on Devon Island used stereo-pair imaging and three-dimensional photographic models to catalog the type and occurrence of patterned ground in the study area. This image catalog was then used to provide new insight into photographic observations gathered by Phoenix. Stereo-pair imagery has been a valuable geoscience tool for decades and it is an ideal tool for comparative planetary geology studies. Stereo-pair images captured on Devon Island were turned into digital elevation models (DEMs) and comparisons were noted between the permafrost and patterned ground environment of Earth and Mars including variations in grain sorting, active layer thickness, and ice table depth. Recent advances in 360° cameras also enabled the creation of a detailed, immersive site models of patterned ground at selected sites in Haughton crater on Devon Island. The information from this ground truth study will enable the development and refinement of existing models to better evaluate patterned ground on Mars and predict its evolution.

    Full Text Available The development of biology and medicine enables that legal and biological maternity and paternity coincide completely, owing to biomedical analysis, in particular to DNA analysis. On the other hand, development of biology and medicine causes discrepancy in legal and biological maternity and paternity in the situation of biomedically assisted conception if donor genetic material is used. Thus, autonomy of the parties gain in importance, legal parental relations are based on the will of the parties, so principle of biological truth looses importance. Legal parents would be persons who participated in the process of biomedically assisted conception in order to get the child. Autonomy of the mother could be extended to allow for anonymous birth. Acknowledgement of the paternity depends almost entirely on the will of the parties concerned. If the man acknowledges his paternity and the requisite consent is given, the man is considered to be the father. The biological truth is not examined. On the other hand, in proceedings for establishing and contesting maternity and paternity, the court is obliged to determine the biological truth, which may be based on DNA and other biomedical evidence. It could be said that the autonomy of the parties is limited by the requirement that maternity and paternity in such cases be established based on the biological facts.

  13. Breaking new ground in mapping human settlements from space - The Global Urban Footprint

    Today, approximately 7.2 billion people inhabit the Earth and by 2050 this number will have risen to around nine billion, of which about 70% will be living in cities. The population growth and the related global urbanization pose one of the major challenges to a sustainable future. Hence, it is essential to understand drivers, dynamics, and impacts of the human settlements development. A key component in this context is the availability of an up-to-date and spatially consistent map of the location and distribution of human settlements. It is here that the Global Urban Footprint (GUF) raster map can make a valuable contribution. The new global GUF binary settlement mask shows a so far unprecedented spatial resolution of 0.4″ (∼ 12m) that provides - for the first time - a complete picture of the entirety of urban and rural settlements. The GUF has been derived by means of a fully automated processing framework - the Urban Footprint Processor (UFP) - that was used to analyze a global coverage of more than 180,000 TanDEM-X and TerraSAR-X radar images with 3 m ground resolution collected in 2011-2012. The UFP consists of five main technical modules for data management, feature extraction, unsupervised classification, mosaicking and post-editing. Various quality assessment studies to determine the absolute GUF accuracy based on ground truth data on the one hand and the relative accuracies compared to established settlements maps on the other hand, clearly indicate the added value of the new global GUF layer, in particular with respect to the representation of rural settlement patterns. The Kappa coefficient of agreement compared to absolute ground truth data, for instance, shows GUF accuracies which are frequently twice as high as those of established low resolution maps. Generally, the GUF layer achieves an overall absolute accuracy of about 85%, with observed minima around 65% and maxima around 98%. The GUF will be provided open and free for any scientific use in

    Full Text Available The December 2006 Iran Holocaust denial Conference and the international excoriation of it reveal a paradox of two cultural strands that are emblematic of the legacy of the twentieth century: official denial and historical amnesia on the one hand; and (international attempts at truth telling and historical redress on the other. Massive violence–and associative denial—punctuate the entire twentieth century. Yet coordinated tenacious efforts at public acknowledgment of “what really happened”–a recurrent and insistent emphasis in this context of trials, reparations, and above all, truth commissions—and concomitant historical redress for state-sanctioned crimes is a particularly recent phenomenon, unique, in fact, to the 1990s. But it is not only political readers who address what Priscilla B. Hayner, in her exhaustive study of truth commissions calls, “unspeakable truths.” This essay addresses the incongruity between the recent global concern with truth telling, official apology, memory and historical redress on the one hand–an obsession that certainly includes the US—and American amnesia on the other. It is in the interstices of these two apposite late twentieth century phenomena–amnesia and truth telling; “history” distinct from “the truth of the past”; “official” opposed to “vernacular” memory — that, I argue, a new genre of historical novel develops and performs a vital cultural work: telling the truth in an age of amnesia and redress. Such novels engage the recalcitrant materials of historical experience to assert truth claims that in turn challenge nationalist histories and revise traditional mythologies. Among the foremost authors of this new “truth-telling” historical novel is Don DeLillo. Americana, the vital precursor to Libra and especially to Underworld, is the definitive harbinger of DeLillo’s third century of work that writes both within and against postmodernism.

    In childhood we learned many myths about radiation. For example, we were told that people exposed to x-rays would glow in the dark, become radioactive, or under the proper circumstances, turn into superhumans such as the ''Hulk'' or ''Spiderman.'' Although these and other childhood myths are not taken seriously, many misconceptions still exist about the effects of ionizing radiation. Does exposure to radiation necessarily imply an ill fate? It is the intent of this chapter to highlight a few of the truths and fallacies concerning radiation and its effects

    This water sampling and analysis plan summarizes the results of previous water sampling activities and the plan for water sampling activities for calendar year 1994. A buffer zone monitoring plan is included as an appendix. The buffer zone monitoring plan is designed to protect the public from residual contamination that entered the ground water as a result of former milling operations. Surface remedial action at the Gunnison Uranium Mill Tailings Remedial Action Project site began in 1992; completion is expected in 1995. Ground water and surface water will be sampled semiannually in 1994 at the Gunnison processing site (GUN-01) and disposal site (GUN-08). Results of previous water sampling at the Gunnison processing site indicate that ground water in the alluvium is contaminated by the former uranium processing activities. Background ground water conditions have been established in the uppermost aquifer (Tertiary gravels) at the Gunnison disposal site. The monitor well locations provide a representative distribution of sampling points to characterize ground water quality and ground water flow conditions in the vicinity of the sites. The list of analytes has been modified with time to reflect constituents that are related to uranium processing activities and the parameters needed for geochemical evaluation. Water sampling will be conducted at least semiannually during and one year following the period of construction activities, to comply with the ground water protection strategy discussed in the remedial action plan (DOE, 1992a)

    Full Text Available Northern Caspian Region is a part of the territory of Russia. On the territory of the Northern Caspian Region arid and semi-arid landscapes exist and are used as pastures for ages. Mining, construction, installation and operation of communications, cultivation of land make significant impact to the environmental change of this territory. Desertification is the most typical respond to irrational environmental impact for the arid areas, and assessment of the current status and trends of desertification of the territory are necessary to determine the plans for the development and environment restoration missions. Four scenes from Landsat-8 (OLI, June 2014 have been processed via ENVI software. Top of the surface reflectance have been calculated, supervised and classified using ROI based on ground truth data. Based on the remote sensing data area of desertification was estimated and created a map “Desertification of the Northern Caspian Region.” The obtained data are preliminary and require further clarification, including verification by ground truth and further research.

  20. Models for truth-telling in physician-patient encounters: what can we learn from Yoruba concept of Ooto?

    Ewuoso, Cornelius

    2017-09-29

    Empirical studies have now established that many patients make clinical decisions based on models other than Anglo American model of truth-telling and patient autonomy. Some scholars also add that current medical ethics frameworks and recent proposals for enhancing communication in health professional-patient relationship have not adequately accommodated these models. In certain clinical contexts where health professional and patients are motivated by significant cultural and religious values, these current frameworks cannot prevent communication breakdown, which can, in turn, jeopardize patient care, cause undue distress to a patient in certain clinical contexts or negatively impact his/her relationship with the community. These empirical studies have now recommended that additional frameworks developed around other models of truth-telling; and which take very seriously significant value-differences which sometimes exist between health professional and patients, as well as patient's cultural/religious values or relational capacities, must be developed. This paper contributes towards the development of one. Specifically, this study proposes a framework for truth-telling developed around African model of truth-telling by drawing insights from the communitarian concept of ootọ́ amongst the Yoruba people of south west Nigeria. I am optimistic that if this model is incorporated into current medical ethics codes and curricula, it will significantly enhance health professional-patient communication. © 2017 John Wiley & Sons Ltd.

    Medical imaging modalities such as computed tomography (CT) combined with computer-aided diagnostic processing have already become important part of clinical routine specially for pleural diseases. The segmentation of the thoracic cavity represents an extremely important task in medical imaging for different reasons. Multiple features can be extracted by analyzing the thoracic cavity space and these features are signs of pleural diseases including the malignant pleural mesothelioma (MPM) which is the main focus of our research. This paper presents a method that detects the MPM in the thoracic cavity and plans the photodynamic therapy in the preoperative phase. This is achieved by using a texture analysis of the MPM region combined with a thoracic cavity segmentation method. The algorithm to segment the thoracic cavity consists of multiple stages. First, the rib cage structure is segmented using various image processing techniques. We used the segmented rib cage to detect feature points which represent the thoracic cavity boundaries. Next, the proposed method segments the structures of the inner thoracic cage and fits 2D closed curves to the detected pleural cavity features in each slice. The missing bone structures are interpolated using a prior knowledge from manual segmentation performed by an expert. Next, the tumor region is segmented inside the thoracic cavity using a texture analysis approach. Finally, the contact surface between the tumor region and the thoracic cavity curves is reconstructed in order to plan the photodynamic therapy. Using the adjusted output of the thoracic cavity segmentation method and the MPM segmentation method, we evaluated the contact surface generated from these two steps by comparing it to the ground truth. For this evaluation, we used 10 CT scans with pathologically confirmed MPM at stages 1 and 2. We obtained a high similarity rate between the manually planned surface and our proposed method.

    Recent years have witnessed the rise of populism and populist leaders, movements and policies in many pluralist liberal democracies, with Brexit and the election of Trump the two most recent high profile examples of this backlash against established political elites and the institutions that support them. This new populism is underpinned by a post-truth politics which is using social media as a mouthpiece for ‘fake news’ and ‘alternative facts’ with the intention of inciting fear and hatred of ‘the other’ and thereby helping to justify discriminatory health policies for marginalised groups. In this article, we explore what is meant by populism and highlight some of the challenges for health and health policy posed by the new wave of post-truth populism. PMID:28812811

    An expression of community socialpsychology based on the need to transform social reality, and to considerpeople as the constructors ofthat reality, is examined from an epistemologicalpoint of view. Dualism, the position considering that object and subject are separate entities, and monism, the perspective stating that there is only one substance, are discussed The consequences of both conceptions for community social psychology, and their incompatibility, as well as the notions of reality and truth are analyzed. That analysis deals with the problems of defining reality, of separating subject and object of knowledge, of language's role, and of relativism and truth. Finally, a constructionist view of monism based on relatedness, and action, is proposed, stating the mutually influencing union of subject and object in the construction of reality.

    In their editorial, Speed and Mannion identify two main challenges "the rise of post-truth populism" poses for health policy: the populist threat to inclusive healthcare policies, and the populist threat to well-designed health policies that draw on professional expertise and research evidence. This short comment suggests some conceptual clarifications that might help in thinking through more profoundly these two important issues. It argues that we should approach right-wing populism as a combination of a populist down/up (people/elite) axis with an exclusionary nationalist in/out (member/non-member) axis. And it raises some questions regarding the equation between populism, demagogy and the rejection of expertise and scientific knowledge. PMID:29524956

    2017-01-01

    IMPORTANCE Navigating requests from parents or family caregivers not to disclose poor prognosis to seriously ill children can be challenging, especially when the requests seem culturally mediated. Pediatric clinicians must balance obligations to respect individual patient autonomy, professional truth telling, and tolerance of multicultural values. OBSERVATIONS To provide suggestions for respectful and ethically appropriate responses to nondisclosure requests, we used a hypothetical case example of a Middle Eastern adolescent patient with incurable cancer and conducted an ethical analysis incorporating (1) evidence from both Western and Middle Eastern medical literature and (2) theories of cultural relativism and justice. While Western medical literature tends to prioritize patient autonomy and corresponding truth telling, the weight of evidence from the Middle East suggests high variability between and within individual countries, patient-physician relationships, and families regarding truth-telling practices and preferences. A common reason for nondisclosure in both populations is protecting the child from distressing information. Cultural relativism fosters tolerance of diverse beliefs and behaviors by forbidding judgment on foreign societal codes of conduct. It does not justify assumptions that all individuals within a single culture share the same values, nor does it demand that clinicians sacrifice their own codes of conduct out of cultural respect. We suggest some phrases that may help clinicians explore motivations behind nondisclosure requests and gently confront conflict in order to serve the patient’s best interest. CONCLUSIONS AND RELEVANCE It is sometimes ethically permissible to defer to family values regarding nondisclosure, but such deferral is not unique to cultural differences. Early setting of expectations and boundaries, as well as ongoing exploration of family and health care professional concerns, may mitigate conflict. PMID:28873121

    Full Text Available In this article the two authors problematize the moment of stabilization in doing fieldwork and writing ethnography from a feminist perspective. The paper begins with an introduction to the question: How do feminist science studies scholars reconcile a normative need to stabilize our research site to create knowledge within the shifting ground of “truth claims” that feminist practices acknowledge and document? The heart of the paper reflects on our experiences as feminist theorists, teachers, and ethnographers with vignettes from studies of high-risk pregnancies in the industrialized world, specifically the United States, and gender and everyday technologies in West Africa. Our goal is to theorize this instability in order to highlight the limits and benefits of working with consciousness and reflectivity in social contexts while challenging and enriching the vibrancy of our feminist theory and practice.

  14. Sensitivities and uncertainties of modeled ground temperatures in mountain environments

    2013-08-01

    Full Text Available Model evaluation is often performed at few locations due to the lack of spatially distributed data. Since the quantification of model sensitivities and uncertainties can be performed independently from ground truth measurements, these analyses are suitable to test the influence of environmental variability on model evaluation. In this study, the sensitivities and uncertainties of a physically based mountain permafrost model are quantified within an artificial topography. The setting consists of different elevations and exposures combined with six ground types characterized by porosity and hydraulic properties. The analyses are performed for a combination of all factors, that allows for quantification of the variability of model sensitivities and uncertainties within a whole modeling domain. We found that model sensitivities and uncertainties vary strongly depending on different input factors such as topography or different soil types. The analysis shows that model evaluation performed at single locations may not be representative for the whole modeling domain. For example, the sensitivity of modeled mean annual ground temperature to ground albedo ranges between 0.5 and 4 °C depending on elevation, aspect and the ground type. South-exposed inclined locations are more sensitive to changes in ground albedo than north-exposed slopes since they receive more solar radiation. The sensitivity to ground albedo increases with decreasing elevation due to shorter duration of the snow cover. The sensitivity in the hydraulic properties changes considerably for different ground types: rock or clay, for instance, are not sensitive to uncertainties in the hydraulic properties, while for gravel or peat, accurate estimates of the hydraulic properties significantly improve modeled ground temperatures. The discretization of ground, snow and time have an impact on modeled mean annual ground temperature (MAGT that cannot be neglected (more than 1 °C for several

  15. Civil history and poetry, certainty and truth in Francis Bacon

    2015-02-01

    Full Text Available This article aims at studying key components of Francis Bacon’s theory of history and of his work as practitioner of civil history, particularly in regard to truth and certainty in historical narratives. It compares Bacon’s theories of history and poetry, and the way in which he conceives their relation to certainty, truth and fiction. It analyzes mainly two sorts of writings. On the one hand, it investigates the programmatic texts where Bacon’s views of history and poetry are developed. On the other hand, it examines the finished and unfinished civil histories written by Bacon as historian. In addition, the article evaluates Bacon’s stances against the background of Renaissance and early modern English historiography. It concludes that although history and poetry constitute separate branches in Bacon’s classification of learning, they share important elements, in keeping with the view of poetry maintained by his contemporary Philip Sidney. Thus, Bacon included fictional patterns in his historical narrative and distinguished certainties from conjectures in a particular way. This attitude towards civil history shows a strong contrast to Bacon’s methodology for natural histories, which, in order to reach certainty, staunchly recommends to exclude any fictional narrative in reporting the facts of nature.

    2015-08-01

    Full Text Available Identifying patterns of influence deliberate lie on deferred confidence of reliability of autobiographical memories is current problem for legal psychology. We reviewed the variability of autobiographical memories in the context of legal practice. In addition, we conducted the experimental field study of the dynamics of subjective assessments of the reliability of memories. It was found that truthful confirmation and false refutation of reliable last episodes, as well as after a truthful refutation and false confirmation of unreliable last episodes lead to regular changes in the subjective assessment of the reliability. The mnemonic "renunciation effect" is that a false refutation of a reliable episode leads to its forgetting and a truthful refutation of an unreliable episode leads to its erroneous inclusion in autobiographical memory.

    2016-04-01

    In recent years, Unmanned Aerial Vehicles (UAV) have seen widespread civil applications including usage for survey and monitoring services in areas such as agriculture, construction and civil engineering, private surveillance and reconnaissance services and cultural heritage management. Most aerial monitoring services require the integration of information acquired during the flight (such as imagery) with ground-based information (such as GPS information or others) for improved ground truth validation. For example, to obtain an accurate 3D and Digital Elevation Model based on aerial imagery, it is necessary to include ground-based information of coordinate points, which are normally acquired with surveying methods based on Global Position Systems (GPS). However, GPS surveys are very time consuming and especially for longer time series of monitoring data repeated GPS surveys are necessary. In order to improve speed of data collection and integration, this work presents an autonomous system based on Waspmote technologies build on single nodes interlinked in a Wireless Sensor Network (WSN) star-topology for ground based information collection and later integration with surveying data obtained by UAV. Nodes are designed to be visible from the air, to resist extreme weather conditions with low-power consumption. Besides, nodes are equipped with GPS as well as Inertial Measurement Unit (IMU), accelerometer, temperature and soil moisture sensors and thus provide significant advantages in a broad range of applications for environmental monitoring. For our purpose, the WSN transmits the environmental data with 3G/GPRS to a database on a regular time basis. This project provides a detailed case study and implementation of a Ground Control Point System Network for UAV-based vegetation monitoring of dry mountain grassland in the Matsch valley, Italy.

By the discovering the biblical truth everybody can understand better oneself, the creation and God. Everybody can concisely grow in one’s faith. According to the document, the Divine inspiration is revealed to us when we read the Holy Scriptures. On the pages of Bible we can meet God himself. The message shared with us in the Bible explains the truth about God, about a man, our salvation and about a world. Even though it has some elements of the science or history, it is not a source of the science knowledge or chronicle of the historic facts.

  20. Deception and the death of Ilyusha: truth and the best interest of a dying child in The Brothers Karamazov.

    For centuries, many physicians and parents assumed that it was ethically justifiable to lie to a dying child. The reasoning was clear. Because the lie would likely eliminate or prevent a concrete harm (the child's fear), and the lie is about a harm that is unavoidable anyway, a lie appeared to be the morally desirable thing to do. Today, the ethical consensus has shifted. Many doctors and other health professionals now argue that we have an obligation to tell children the cold, hard truth. In this article, I argue that "the cold, hard truth" (assuming we can know it with certainty) might not always be in the best interest of the patient. To illustrate the point, I analyze an episode in Dostoevsky's novel, The Brothers Karamazov, in which a child is dying, his father lies to him about it, and 2 doctors take very different approaches to the truth. Each of these individuals has a particular interest when it comes to the question of "the truth" about the death of Ilyusha. I use this story to ask whether it is ethically permissible to lie to a dying child and, if so, who has the moral authority to tell that lie. Copyright © 2014 by the American Academy of Pediatrics.

    Full Text Available Recent years have witnessed the rise of populism and populist leaders, movements and policies in many pluralist liberal democracies, with Brexit and the election of Trump the two most recent high profile examples of this backlash against established political elites and the institutions that support them. This new populism is underpinned by a post-truth politics which is using social media as a mouthpiece for ‘fake news’ and ‘alternative facts’ with the intention of inciting fear and hatred of ‘the other’ and thereby helping to justify discriminatory health policies for marginalised groups. In this article, we explore what is meant by populism and highlight some of the challenges for health and health policy posed by the new wave of post-truth populism.

  3. Living the categorical imperative: autistic perspectives on lying and truth telling-between Kant and care ethics.

    Lying is a common phenomenon amongst human beings. It seems to play a role in making social interactions run more smoothly. Too much honesty can be regarded as impolite or downright rude. Remarkably, lying is not a common phenomenon amongst normally intelligent human beings who are on the autism spectrum. They appear to be 'attractively morally innocent' and seem to have an above average moral conscientious objection against deception. In this paper, the behavior of persons with autism with regard to deception and truthfulness will be discussed in the light of two different ethical theories, illustrated by fragments from autobiographies of persons with autism. A systemizing 'Kantian' and an empathizing 'ethics of care' perspective reveal insights on high-functioning autism, truthfulness and moral behavior. Both perspectives are problematic from the point of view of a moral agent with autism. High-functioning persons with autism are, generally speaking, strong systemizes and weak empathizers. Particularly, they lack 'cognitive empathy' which would allow them to understand the position of the other person. Instead, some tend to invent a set of rules that makes their behavior compatible with the expectations of others. From a Kantian point of view, the autistic tendency to always tell the truth appears praiseworthy and should not be changed, though it creates problems in the social life of persons with autism. From a care ethics perspective, on the other hand, a way should be found to allow the high-functioning persons with autism to respect the feelings and needs of other persons as sometimes overruling the duty of truthfulness. We suggest this may even entail 'morally educating' children and adolescents with autism to become socially skilled empathic 'liars'.

  4. Reputation mechanism: From resolution for truthful online auctions to the model of optimal one-gambler problem

    In this paper we study reputation mechanisms, and show how the notion of reputation can help us in building truthful online auction mechanisms. From the mechanism design prospective, we derive the conditions on and design a truthful online auction mechanism. Moreover, in the case when some agents may lay or cannot have the real knowledge about the other agents reputations, we derive the resolution of the auction, such that the mechanism is truthful. Consequently, we move forward to the optimal one-gambler/one-seller problem, and explain how that problem is refinement of the previously discussed online auction design in the presence of reputation mechanism. In the setting of the optimal one-gambler problem, we naturally rise and solve the specific question: What is an agent's optimal strategy, in order to maximize his revenue? We would like to stress that our analysis goes beyond the scope, which game theory usually discusses under the notion of reputation. We model one-player games, by introducing a new parameter (reputation), which helps us in predicting the agent's behavior, in real-world situations, such as, behavior of a gambler, real-estate dealer, etc.

  6. Results of detailed ground geophysical surveys for locating and differentiating waste structures in waste management area 'A' at Chalk River Laboratories, Ontario

    1999-01-01

    Waste Management Area 'A' (WMA 'A'), located in the outer area of the Chalk River Laboratories (CRL) was in use as a waste burial site from 1946 to 1955. Waste management structures include debris-filled trenches, concrete bunkers and miscellaneous contaminated solid materials, and ditches and pits used for liquid dispersal. In order to update historical records, it was proposed to conduct detailed ground geophysical surveys to define the locations of waste management structures in WMA 'A', assist in planning of the drilling and sampling program to provide ground truth for the geophysics investigation and to predict the nature and locations of unknown/undefined shallow structures. A detailed ground geophysical survey grid was established with a total of 127 grid lines, oriented NNE and spaced one metre apart. The geophysical surveys were carried out during August and September, 1996. The combination of geophysical tools used included the Geonics EM61 metal detector, the GSM-19 magnetometer/gradiometer and a RAMAC high frequency ground penetrating radar system. The geophysical surveys were successful in identifying waste management structures and in characterizing to some extent, the composition of the waste. The geophysical surveys are able to determine the presence of most of the known waste management structures, especially in the western and central portions of the grid which contain the majority of the metallic waste. The eastern portion of the grid has a completely different geophysical character. While historical records show that trenches were dug, they are far less evident in the geophysical record. There is clear evidence for a trench running between lines 30E and 63E at 70 m. There are indications from the radar survey of other trench-like structures in the eastern portion. EM61 data clearly show that there is far less metallic debris in the eastern portion. The geophysical surveys were also successful in identifying previously unknown locations of waste

    Among the strengths of forensic psychiatry as a profession is its ability to support lively discussion of critical questions, such as how to characterize its own essence and whether it belongs to the practice of medicine. The American Academy of Psychiatry and the Law is fortunate that Michael Norko has taken the occasion of his presidential address to describe in depth the results of the advanced stage of his probing on a truly spiritual level the fundamental place of compassion in the practice of forensic psychiatry. In so doing, he casts inevitable light on the seamless connections binding forensic psychiatry and medicine, particularly the importance for both of practicing compassion in our search for truth. © 2018 American Academy of Psychiatry and the Law.

These traditionally arise from any discussion on logical and semantical paradoxes. This particular volume, however, is not concerned with paradoxes but with the investigation of type-free sytems to show that: (i) there are rich theories of self-application, involving both operations and truth which can serve as foundations for property theory and formal semantics; (ii) these theories provide a new outlook on classical

    Full Text Available Considering the complexity of circumstances that journalism is facing, academia should rethink the classical conceptions of the profession, especially when they reduce journalism to abstract models disregarding reporters’ actual practices. Results of a global research propose a new definition of journalism, a profession caught between conflicting interests that lack the supremacy of news production, as it used to be in the past century. It is all about broadening the debate to reconsider the role of the journalist in the contemporary information report, beyond current concepts such as post-truth.

    This guide deals with the legislation, planning, building, usage and maintenance of ground-source heat systems. The guide gives recommendations and instructions on national level on the permit practices and how to carry out the whole ground-source heat system project. The main focus of the guide is on energy wells for one-family houses. The principle is that an action permit is needed to build a ground-source heat system. On ground water areas a permit according to the water act may also be required. To avoid any problems, the placement of the system needs to be planned precisely. This guide gives a comprehension to the orderer on the issues that need to be considered before ordering, during construction, when the system is running and when giving up the use of the ground-source heat system.

    2014-01-01

    Purpose: Accurate on-line reconstruction of in-vivo volume dose that accounts for both machine and patient discrepancy is not clinically available. We present a simple reference-dose-perturbation algorithm that reconstructs in-vivo volume dose fast and accurately. Methods: We modelled the volume dose as a function of the fluence map and density image. Machine (output variation, jaw/leaf position errors, etc.) and patient (setup error, weight loss, etc.) discrepancies between the plan and delivery were modelled as perturbation of the fluence map and density image, respectively. Delivered dose is modelled as perturbation of the reference dose due to change of the fluence map and density image. We used both simulated and clinical data to validate the algorithm. The planned dose was used as the reference. The reconstruction was perturbed from the reference and accounted for output-variations and the registered daily image. The reconstruction was compared with the ground truth via isodose lines and the Gamma Index. Results: For various plans and geometries, the volume doses were reconstructed in few seconds. The reconstruction generally matched well with the ground truth. For the 3%/3mm criteria, the Gamma pass rates were 98% for simulations and 95% for clinical data. The differences mainly appeared on the surface of the phantom/patient. Conclusions: A novel reference-dose-perturbation dose reconstruction model is presented. The model accounts for machine and patient discrepancy from planning. The algorithm is simple, fast, yet accurate, which makes online in-vivo 3D dose reconstruction clinically feasible.

  14. An Apology for Philosophy: On the contested relationship between truth and politics

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available The starting point of this paper is Hannah Arendt’s diagnosis that the introduction of philosophical truth into politics leads to tyrannical or totalitarian outcomes. A critique of this diagnosis is offered on the basis of Michel Foucault’s last lectures at the Collège de France where he discussed the practices of parrēsia, “truth-telling,” as multiple forms of political life of resistance, critique, and contestation. The common denominator of all parrhēsiastic practices is that none of them are concerned with “doctrines.” That is, none of them are concerned with laying out the “content” of politics. After the paper has identified and expounded four different manifestations of parrēsia—“political” (Pericles, “philosophical” (Plato, “philosophical-ethical” (Socrates and “ethical” (Diogenes the Cynic—an argument is presented for a kinship, instead of a difference, between Foucault and Arendt as parrhēsiastic or critical thinkers within the same tradition of political Kantianism.

    2009-06-01

    Full Text Available In the first of four lectures on Nietzsche’s philosophy, “The Will to Poweras Art” (1936-37, Heidegger argues that the unique and importantrelationship between truth and art, which Nietzsche suggests, must beunderstood “with a view to the conquest of nihilism,” i.e., within the historical context of a radically novel interpretation of sensuous reality. Beginning with the project of overturning Platonism as the active countermovement to nihilism, this essay interprets Heidegger’s difficult notion of the discordant relationship between truth (the fixation of semblance and art (the transfiguration of semblance in Nietzsche’s philosophy, emphasizing the supreme importance of art as life’s greatest enhancing force. The analysis is conducted within the context of Nietzsche’s metaphysics as presented by Heidegger, who claims thatas a metaphysical thinker, Nietzsche could not explain such topics as “truth,” “Being,” and “Becoming” in terms beyond the conceptualization of Western philosophy. In spite of that, his thought intimates a movement beyond the constraints of the tradition within which he was entrenched. In addition to providing a detailed exegesis of Heidegger’s lecture course, the problems associated with Heidegger’s metaphysical interpretation of Nietzsche’s philosophy will be discussed, problems that commentators such as Alan Schrift (Nietzsche and the Question of Interpretation believe stem from Heidegger’s stringent and restrictive methodological choices for approaching the reading of Nietzsche.

    1989-01-01

    The SP-100 program is in the midst of developing and demonstrating the technology of a liquid-metal-cooled fast reactor using thermoelectric thermal-to-electric conversion devices for space power applications in the range of tens to hundreds of kilowatts. The current ground engineering system (GES) design and development phase will demonstrate the readiness of the technology building blocks and the system to proceed to flight system validation. This phase includes the demonstration of a 2.4-MW(thermal) reactor in the nuclear assembly test (NAT) and aerospace subsystem in the integrated assembly test (IAT). The next phase in the SP-100 development, now being planned, is to be a flight demonstration of the readiness of the technology to be incorporated into future military and civilian missions. This planning will answer questions concerning the logical progression of the GES to the flight validation experiment. Important issues in planning the orderly transition include answering the need to plan for a second reactor ground test, the method to be used to test the SP-100 for acceptance for flight, the need for the IAT prior to the flight-test configuration design, the efficient use of facilities for GES and the flight experiment, and whether the NAT should be modified based on flight experiment planning

    Intensity-modulated radiation treatment (IMRT) plan optimization needs beamlet dose distributions. Pencil-beam or superposition/convolution type algorithms are typically used because of their high computational speed. However, inaccurate beamlet dose distributions may mislead the optimization process and hinder the resulting plan quality. To solve this problem, the Monte Carlo (MC) simulation method has been used to compute all beamlet doses prior to the optimization step. The conventional approach samples the same number of particles from each beamlet. Yet this is not the optimal use of MC in this problem. In fact, there are beamlets that have very small intensities after solving the plan optimization problem. For those beamlets, it may be possible to use fewer particles in dose calculations to increase efficiency. Based on this idea, we have developed a new MC-based IMRT plan optimization framework that iteratively performs MC dose calculation and plan optimization. At each dose calculation step, the particle numbers for beamlets were adjusted based on the beamlet intensities obtained through solving the plan optimization problem in the last iteration step. We modified a GPU-based MC dose engine to allow simultaneous computations of a large number of beamlet doses. To test the accuracy of our modified dose engine, we compared the dose from a broad beam and the summed beamlet doses in this beam in an inhomogeneous phantom. Agreement within 1% for the maximum difference and 0.55% for the average difference was observed. We then validated the proposed MC-based optimization schemes in one lung IMRT case. It was found that the conventional scheme required 10(6) particles from each beamlet to achieve an optimization result that was 3% difference in fluence map and 1% difference in dose from the ground truth. In contrast, the proposed scheme achieved the same level of accuracy with on average 1.2 × 10(5) particles per beamlet. Correspondingly, the computation

    Hoffman, Singh, and Prakash (Psychonomic Review and Bulletin, 2015, in press) intend to show that perceptions are evolutionarily tuned to fitness rather than to truth. I argue, partly in accordance with their objective, that issues of 'truth' or 'veridicality' have no place in explanatory accounts of perception theory, and rather belong to either ordinary discourse or to philosophy. I regard, however, their general presumption that the evolutionary development of core achievements of the human perceptual system would be primarily determined by aspects of fitness and adaption as unwarranted in light of the evidence available.

    1994-11-01

    This water sampling and analysis plan summarizes the results of previous water sampling activities and the plan for future water sampling activities, in accordance with the Guidance Document for Preparing Sampling and Analysis Plans for UMTRA Sites. A buffer zone monitoring plan for the Dos Rios Subdivision is included as an appendix. The buffer zone monitoring plan was developed to ensure continued protection to the public from residual contamination. The buffer zone is beyond the area depicted as contaminated ground water due to former milling operations. Surface remedial action at the Gunnison Uranium Mill Tailings Remedial Action Project site began in 1992; completion is expected in 1995. Ground water and surface water will be sampled semiannually at the Gunnison processing site and disposal site. Results of previous water sampling at the Gunnison processing site indicate that ground water in the alluvium is contaminated by the former uranium processing activities. Background ground water conditions have been established in the uppermost aquifer at the Gunnison disposal site. The monitor well locations provide a representative distribution of sampling points to characterize ground water quality and ground water flow conditions in the vicinity of the sites. The list of analytes has been modified with time to reflect constituents that are related to uranium processing activities and the parameters needed for geochemical evaluation

    The final disposal facility for spent nuclear fuel is part of the KBS-3 system, which also consists of a central facility for interim storage and encapsulation of the spent nuclear fuel and a transport system. The nuclear fuel repository will be a nuclear facility. Regulation SSMFS 2008:1 (Swedish Radiation Safety Authority's regulations on safety of nuclear facilities) requires that the licensee must have a current decommissioning plan throughout the facility lifecycle. Before the facility is constructed, a preliminary decommissioning plan should be reported to the Swedish Radiation Safety Authority. This document is a preliminary decommissioning plan, and submitted as an attachment to SKB's application for a license under the Nuclear Activities Act to construct, own and operate the facility. The final disposal facility for spent nuclear fuel consists of an above ground part and a below ground part and will be built near Forsmark and the final repository for radioactive operational waste, SFR. The parts above and below ground are connected by a ramp and several shafts, e.g. for ventilation. The below ground part consists of a central area, and several landfill sites. The latter form the repository area. The sealed below ground part constitutes the final repository. The decommissioning is taking place after the main operation has ended, that is, when all spent nuclear fuel has been deposited and the deposition tunnels have been backfilled and plugged. The decommissioning involves sealing of the remaining parts of the below ground part and demolition of above ground part. When decommissioning begins, there will be no contamination in the facility. The demolition is therefore performed as for a conventional plant. Demolition waste is sorted and recycled whenever possible or placed in landfill. Hazardous waste is managed in accordance with current regulations. A ground investigation is performed and is the basis for after-treatment of the site. The timetable

  8. Finding Common Ground Between Earth Scientists and Evangelical Christians

    Science.gov (United States)

    Grant Ludwig, L.

    2015-12-01

    In recent decades there has been some tension between earth scientists and evangelical Christians in the U.S., and this tension has spilled over into the political arena and policymaking on important issues such as climate change. From my personal and professional experience engaging with both groups, I find there is much common ground for increasing understanding and communicating the societal relevance of earth science. Fruitful discussions can arise from shared values and principles, and common approaches to understanding the world. For example, scientists and Christians are engaged in the pursuit of truth, and they value moral/ethical decision-making based on established principles. Scientists emphasize the benefits of research "for the common good" while Christians emphasize the value of doing "good works". Both groups maintain a longterm perspective: Christians talk about "the eternal" and geologists discuss "deep time". Both groups understand the importance of placing new observations in context of prior understanding: scientists diligently reference "the literature" while Christians quote "chapter and verse". And members of each group engage with each other in "fellowship" or "meetings" to create a sense of community and reinforce shared values. From my perspective, earth scientists can learn to communicate the importance and relevance of science more effectively by engaging with Christians in areas of common ground, rather than by trying to win arguments or debates.

    2015-01-01

    The project will use high-fidelity physics models and simulations to simulate real-time operations of cryogenic and systems and calculate the status/health of the systems. The project enables the delivery of system health advisories to ground system operators. The capability will also be used to conduct planning and analysis of cryogenic system operations. This project will develop and implement high-fidelity physics-based modeling techniques tosimulate the real-time operation of cryogenics and other fluids systems and, when compared to thereal-time operation of the actual systems, provide assessment of their state. Physics-modelcalculated measurements (called “pseudo-sensors”) will be compared to the system real-timedata. Comparison results will be utilized to provide systems operators with enhanced monitoring ofsystems' health and status, identify off-nominal trends and diagnose system/component failures.This capability can also be used to conduct planning and analysis of cryogenics and other fluidsystems designs. This capability will be interfaced with the ground operations command andcontrol system as a part of the Advanced Ground Systems Maintenance (AGSM) project to helpassure system availability and mission success. The initial capability will be developed for theLiquid Oxygen (LO2) ground loading systems.

  11. Ground Field-Based Hyperspectral Imaging: A Preliminary Study to Assess the Potential of Established Vegetation Indices to Infer Variation in Water-Use Efficiency.

    Increases in the global average temperature will consequently induce a higher occurrence of severe environmental conditions such as drought on arable land. To mitigate these threats, crops for fuel and food must be bred for higher water-use efficiencies (WUE). Defining genomic variation through high-throughput phenotypic analysis in field conditions has the potential to relieve the major bottleneck in linking desirable genetic traits to the associated phenotypic response. This can subsequently enable breeders to create new agricultural germplasm that supports the need for higher water-use efficient crops. From satellites to field-based aerial and ground sensors, the reflectance properties of vegetation measured by hyperspectral imaging is becoming a rapid high-throughput phenotyping technique. A variety of physiological traits can be inferred by regression analysis with leaf reflectance which is controlled by the properties and abundance of water, carbon, nitrogen and pigments. Although, given that the current established vegetation indices are designed to accentuate these properties from spectral reflectance, it becomes a challenge to infer relative measurements of WUE at a crop canopy scale without ground-truth data collection. This study aims to correlate established biomass and canopy-water-content indices with ground-truth data. Five bioenergy sorghum genotypes (Sorghum bicolor L. Moench) that have differences in WUE and wild-type Tobacco (Nicotiana tabacum var. Samsun) under irrigated and rainfed field conditions were examined. A linear regression analysis was conducted to determine if variation in canopy water content and biomass, driven by natural genotypic and artificial treatment influences, can be inferred using established vegetation indices. The results from this study will elucidate the ability of ground field-based hyperspectral imaging to assess variation in water content, biomass and water-use efficiency. This can lead to improved opportunities to

    Full Text Available Private protected area (PPA conservation agents (CA engaging in development-based conservation in southern Chile have generated conflict with locals. Poor fit of dominant development-based conservation ideology in rural areas is commonly to blame. We developed and administered a cultural consensus survey near the Valdivian Coastal Reserve (RCV and Huilo Huilo Reserve (HH to examine fit of CA cultural truths with local residents. Cultural consensus analysis (CCA of 23 propositions reflecting CA cultural truths confirmed: (1 a single CA culture exists, and (2 RCV communities were more aligned with this culture than HH communities. Inadequate communication, inequitable decision making, divergent opinions about livelihood impacts and trajectories, and PPA purpose may explain differences between CAs and communities. Meanwhile, variability in response between and within communities may reflect differing environmental histories. Private protected area administrations might use CCA to confront cultural differences and thereby improve their community interactions.

  16. Results of detailed ground geophysical surveys for locating and differentiating waste structures in waste management area 'A' at Chalk River Laboratories, Ontario

    Energy Technology Data Exchange (ETDEWEB)

    Tomsons, D.K.; Street, P.J.; Lodha, G.S

    1999-07-01

    Waste Management Area 'A' (WMA 'A'), located in the outer area of the Chalk River Laboratories (CRL) was in use as a waste burial site from 1946 to 1955. Waste management structures include debris-filled trenches, concrete bunkers and miscellaneous contaminated solid materials, and ditches and pits used for liquid dispersal. In order to update historical records, it was proposed to conduct detailed ground geophysical surveys to define the locations of waste management structures in WMA 'A', assist in planning of the drilling and sampling program to provide ground truth for the geophysics investigation and to predict the nature and locations of unknown/undefined shallow structures. A detailed ground geophysical survey grid was established with a total of 127 grid lines, oriented NNE and spaced one metre apart. The geophysical surveys were carried out during August and September, 1996. The combination of geophysical tools used included the Geonics EM61 metal detector, the GSM-19 magnetometer/gradiometer and a RAMAC high frequency ground penetrating radar system. The geophysical surveys were successful in identifying waste management structures and in characterizing to some extent, the composition of the waste. The geophysical surveys are able to determine the presence of most of the known waste management structures, especially in the western and central portions of the grid which contain the majority of the metallic waste. The eastern portion of the grid has a completely different geophysical character. While historical records show that trenches were dug, they are far less evident in the geophysical record. There is clear evidence for a trench running between lines 30E and 63E at 70 m. There are indications from the radar survey of other trench-like structures in the eastern portion. EM61 data clearly show that there is far less metallic debris in the eastern portion. The geophysical surveys were also successful in identifying

  20. Ground water in Creek County, Oklahoma

    Cady, Richard Carlysle

    1937-01-01

    Creek County has been designated as a problem area by the Land Use Planning Section of the Resettlement Administration. Some of the earliest oil fields to brought into production were situated in and near this county, and new fields have been opened from time to time during the ensuing years. The production of the newer fields, however, has not kept pace with the exhaustion of the older fields, and the county now presents an excellent picture of the problems involved in adjusting a population to lands that are nearly depleted of their mineral wealth. Values of land have been greatly depressed; tax collection is far in arrears; tenancy is widespread; and in addition more people will apparently be forced to depend on the income from agriculture than the land seems capable of supporting. The county as a whole is at best indifferently suitable for general farming. The Land Use planning Section proposes to study the present and seemingly immanent maladjustments of population to the resources of the land, and make recommendations for their correction. The writer was detailed to the Land Use Planning Section of Region VIII for the purposes of making studies of ground water problems in the region. In Creek County two investigations were made. In September, 1936, the writer spent about ten days investigating the availability of ground water for the irrigation of garden crops during drouths. If it proved feasible to do this generally throughout the county, the Land Use Planning Section might be able to encourage this practice. The second investigation made by the writer was in regard to the extent to which ground water supplies have been damaged by oil well brines. He was in county for four days late in January 1937, and again in March, 1937. During part of the second field trip he was accompanied by R.M. Dixon, sanitary engineer of the Water Utilization Unit of the Resettlement Administration. (available as photostat copy only)

  2. Environmental radiation monitoring plan for depleted uranium and beryllium areas, Yuma Proving Ground

    International Nuclear Information System (INIS)

    Ebinger, M.H.; Hansen, W.R.

    1994-01-01

    This Environmental Radiation Monitoring Plan (ERM) discusses sampling soils, vegetation, and biota for depleted uranium (DU) and beryllium (Be) at Yuma Proving Ground (YPG). The existing ERM plan was used and modified to more adequately assess the potential of DU and Be migration through the YPG ecosystem. The potential pathways for DU and Be migration are discussed and include soil to vegetation, soil to animals, vegetation to animals, animals to animals, and animals to man. Sample collection will show DU deposition and will be used to estimate DU migration. The number of samples from each area varies and depends on if the firing range of interest is currently used for DU testing (GP 17A) or if the range is not used currently for DU testing (GP 20). Twenty to thirty-five individual mammals or lizards will be sampled from each transect. Air samples and samples of dust in the air fall will be collected in three locations in the active ranges. Thirty to forty-five sediment samples will be collected from different locations in the arroys near the impact areas. DU and Be sampling in the Hard Impact and Soft Impact areas changed only slightly from the existing ERM. The modifications are changes in sample locations, addition of two sediment transport locations, addition of vegetation samples, mammal samples, and air sampling from three to five positions on the impact areas. Analysis of samples for DU or total U by inductively-coupled mass spectroscopy (ICP/MS), cc spectroscopy, neutron activation analysis (NAA), and kinetic phosphorimetric analysis (KPA) are discussed, and analysis for Be by ICP/MS are recommended. Acquiring total U (no isotope data) from a large number of samples and analysis of those samples with relatively high total U concentrations results in fewer isotopic identifications but more information on U distribution. From previous studies, total U concentrations greater than about 3 times natural background are usually DU by isotopic confirmation

    2015-01-01

    Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology readiness levels have been incrementally matured by NASA over the last thirteen years, with most recent support from NASA's Space Technology Mission Directorate (STMD) Game Changing Development Program (GCDP). Recently STMD GCDP has authorized funding and support through fiscal year 2015 (FY15) for continued HIAD ground developments which support a Mars Entry, Descent, and Landing (EDL) study. The Mars study will assess the viability of various EDL architectures to enable a Mars human architecture pathfinder mission planned for mid-2020. At its conclusion in November 2014, NASA's first HIAD ground development effort had demonstrated success with fabricating a 50 W/cm2 modular thermal protection system, a 400 C capable inflatable structure, a 10-meter scale aeroshell manufacturing capability, together with calibrated thermal and structural models. Despite the unquestionable success of the first HIAD ground development effort, it was recognized that additional investment was needed in order to realize the full potential of the HIAD technology capability to enable future flight opportunities. The second HIAD ground development effort will focus on extending performance capability in key technology areas that include thermal protection system, lifting-body structures, inflation systems, flight control, stage transitions, and 15-meter aeroshell scalability. This paper presents an overview of the accomplishments under the baseline HIAD development effort and current plans for a follow-on development effort focused on extending those critical technologies needed to enable a Mars Pathfinder mission.

  10. Historical Fiction and the Allegorical Truth of Colonial Violence in The Proposition

    Directory of Open Access Journals (Sweden)

    Felicity Collins

    2011-04-01

    Full Text Available Firing another shot in the history wars, Prime Minister Howard used his 2006 Australia Day speech to berate postmodern approaches to historical truth. At the same time, a UK-Australia co-production, The Proposition (John Hillcoat, 2005 was enjoying critical acclaim as both a violent revisionist Western and an important film about Australia’s frontier history. It would be tempting to include this frontier film in the cycle of ‘post Mabo’ films exemplified by The Tracker (Rolf de Heer, 2002. Yet unlike The Tracker, The Proposition eschews historical reference in favour of baroque allegory. If The Tracker’s moral fable is clearly a left-liberal intervention in the history wars, The Proposition seems to offer no illumination of the present, only the unredeemed violence of retribution as the irrefutable truth of the frontier, aligning it with the 1976 mini-series, Luke’s Kingdom. This article asks in what sense history persists in the allegorical truth of frontier films which cannot be subsumed into historical representation. I argue that The Proposition offers a philosophical view of history as mediated time, rather than a political view of history as traumatic event. I contrast the popular reception of The Proposition as a revisionist, bushranger Western ‘about’ Australian history, with Routt’s counter-claim that The Proposition is an art film ‘about’ violence, revealing Australia as ‘a primal scene of annihilation.’ However, in order not to reinstate the myth of a fatal landscape as the template of Australian identity, I turn to Benjamin’s critique of Baroque allegory as a retrospective mode in which the transience of time finds expression in decay, ruin and debris. The question to be resolved is whether, by giving us multiple horizons of historical time, the revisionist film avoids being drawn into allegory’s melancholy alliance with myth, opening instead into a cinematic revelation of history’s unrealised potential.

  11. Work plan for ground water elevation data recorder/monitor well installation at Gunnison, Colorado. Revision 1

    International Nuclear Information System (INIS)

    1994-08-01

    The purpose of this document is to describe the work that will be performed and the procedures that will be followed during installation of ground water monitor wells and ground water elevation data recorders (data loggers) at the Gunnison, Colorado, Uranium Mill Tailings Remedial Action (UMTRA) Project site. The monitor wells and data loggers will be used to gather required time-dependent data to investigate the interaction between ground water and surface water in the area. Data collection objectives (DCO) identify reasons for collecting data. The following are DCOs for the Gunnison ground water elevation data recorder/monitor well installation project: long-term continuous ground water level data and periodic ground water samples will be collected to better understand the relationship between surface and ground water at the site; water level and water quality data will eventually be used in future ground water modeling to more firmly establish numerical model boundary conditions in the vicinity of the Gunnison processing site; and modeling results will be used to demonstrate and document the potential remedial alternative of natural flushing

    2013-02-01

    Full Text Available Men have been using herbal medicines for thousands of years. The advantages of this type of therapeutics include good availability, local cultural aspects, individual preferences, the increasing demand for natural and organic products, and the already validated synergistic effects of herbal medicines. However, ethically, the scope and limits of these drugs need to be established not only by ethnopharmacological evidences but also by scientific investigations, which confirm the therapeutic effects. With this study, we propose to discuss the possible advantages of using herbal medicines instead of purified compounds, the truth and myths about herbal medicines, drug discovery, and the implications for medical education and health care.

  17. Truth Telling in the Setting of Cultural Differences and Incurable Pediatric Illness: A Review.

    2017-11-01

    Navigating requests from parents or family caregivers not to disclose poor prognosis to seriously ill children can be challenging, especially when the requests seem culturally mediated. Pediatric clinicians must balance obligations to respect individual patient autonomy, professional truth telling, and tolerance of multicultural values. To provide suggestions for respectful and ethically appropriate responses to nondisclosure requests, we used a hypothetical case example of a Middle Eastern adolescent patient with incurable cancer and conducted an ethical analysis incorporating (1) evidence from both Western and Middle Eastern medical literature and (2) theories of cultural relativism and justice. While Western medical literature tends to prioritize patient autonomy and corresponding truth telling, the weight of evidence from the Middle East suggests high variability between and within individual countries, patient-physician relationships, and families regarding truth-telling practices and preferences. A common reason for nondisclosure in both populations is protecting the child from distressing information. Cultural relativism fosters tolerance of diverse beliefs and behaviors by forbidding judgment on foreign societal codes of conduct. It does not justify assumptions that all individuals within a single culture share the same values, nor does it demand that clinicians sacrifice their own codes of conduct out of cultural respect. We suggest some phrases that may help clinicians explore motivations behind nondisclosure requests and gently confront conflict in order to serve the patient's best interest. It is sometimes ethically permissible to defer to family values regarding nondisclosure, but such deferral is not unique to cultural differences. Early setting of expectations and boundaries, as well as ongoing exploration of family and health care professional concerns, may mitigate conflict.

    2012-01-15

    This report presents survey description and results of ground magnetic measurements carried out by GeoVista AB at Aespoe in December, 2011. The purpose of the ground magnetic measurement was to measure variations in the earth magnetic field and to gain knowledge of the magnetization of the bedrock in an area where SKB plan to build a facility for calibration of equipment for measurements of borehole orientation. A total of 312 data points were collected along three survey lines, 104 points/profile. The data show nice and smooth variations that appear to be natural. There is a clear consistency of the magnetic field variations between the three survey lines, which indicates that the variations in the magnetic field reflect geological variations related to lithology and content of magnetic minerals. There are no indications of artifacts or erroneous data. The anomaly field averages at -32 nT with peak values of Min = -1,016 nT and Max = +572 nT. The strongest anomalies occur at profile length c. 130-140 m. Adding the background field of 50,823 nT, measured at a base station located close to the survey area, the total magnetic field averages at 50,791+-226 nT. The ground magnetic measurement gives background information before the construction of the calibration facility. The magnetic anomaly at c. 130-140 m give possibilities to control disturbances of magnetic-accelerometer based instruments. The magnetic measurements show that it is possible to construct the facility at the site
