Full Text Available In this paper we discuss in which sense truth is considered as a mathematical object in propositional logic. 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.

Micro CT based truth estimation of nodule volume

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%).

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.

An existential theory of truth

Directory of Open Access Journals (Sweden)

Dale Cannon

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.

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

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

2014-11-01

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.

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

Directory of Open Access Journals (Sweden)

ANDREEA CONSTANTINESCU

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.

2016-07-01

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.

Ostensibly, there has been a recent rise in ‘post-truth’ thinking (Higgins, 2016; Rochlin, 2017; Speed & Mannion, 2017; Suiter, 2016). The Oxford English Dictionary, which made ‘post-truth’ its word of the year for 2016, defines post-truth as “[r]elating to or denoting circumstances in which objective facts are less influential in shaping political debate or public opinion than appeals to emotion and personal belief” (“Post-truth,” 2017).

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.

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

Directory of Open Access Journals (Sweden)

Bodo eRückauer

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.

The Notion of Truth and Our Evolving Understanding of Sexual Harassment.

Science.gov (United States)

Recupero, Patricia R

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.

AND THE TRUTH SHALL SET YOU FREE. TRUTH COMMISSIONS AND CIVIL-MILITARY RELATIONS

Directory of Open Access Journals (Sweden)

Michael DELOACH

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.

A Bayesian truth serum for subjective data.

Prelec, Drazen

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'

Keller, Evelyn Fox

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.

[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.

STS, symmetry and post-truth.

Science.gov (United States)

Lynch, Michael

2017-08-01

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.

Ground truth measurements plan for the Multispectral Thermal Imager (MTI) satellite

Energy Technology Data Exchange (ETDEWEB)

Garrett, A.J.

2000-01-03

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.

2000-05-01

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 This paper is based on the words of welcome to the symposium on Religion and the Body on 16 June 2010. 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.

Accurate seismo-acoustic source location is one of the fundamental aspects of nuclear explosion monitoring. Critical to improved location is the compilation of ground truth data sets for which origin time and location are accurately known. Substantial effort by the National Laboratories and other seismic monitoring groups have been undertaken to acquire and develop ground truth catalogs that form the basis of location efforts (e.g. Sweeney, 1998; Bergmann et al., 2009; Waldhauser and Richards, 2004). In particular, more GT1 (Ground Truth 1 km) events are required to improve three-dimensional velocity models that are currently under development. Mine seismicity can form the basis of accurate ground truth datasets. Although the location of mining explosions can often be accurately determined using array methods (e.g. Harris, 1991) and from overhead observations (e.g. MacCarthy et al., 2008), accurate origin time estimation can be difficult. Occasionally, mine operators will share shot time, location, explosion size and even shot configuration, but this is rarely done, especially in foreign countries. Additionally, shot times provided by mine operators are often inaccurate. An inexpensive, ground truth event detector that could be mailed to a contact, placed in close proximity (< 5 km) to mining regions or earthquake aftershock regions that automatically transmits back ground-truth parameters, would greatly aid in development of ground truth datasets that could be used to improve nuclear explosion monitoring capabilities. We are developing an inexpensive, compact, lightweight smart sensor unit (or units) that could be used in the development of ground truth datasets for the purpose of improving nuclear explosion monitoring capabilities. The units must be easy to deploy, be able to operate autonomously for a significant period of time (> 6 months) and inexpensive enough to be discarded after useful operations have expired (although this may not be part of our business

Receiver operator characteristic (ROC) analysis without truth

International Nuclear Information System (INIS)

Henkelman, R.M.; Kay, I.; Bronskill, M.J.

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

Can partisan voting lead to truth?

Science.gov (United States)

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.

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.

An inconvenient truth

International Nuclear Information System (INIS)

Al, Gore

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)

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.

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...

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.

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

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.

The truth on journalism: relations between its practice and discourse

Directory of Open Access Journals (Sweden)

Daiane Bertasso Ribeiro

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.

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.

Discerning truth from deception: The sincere witness profile

Directory of Open Access Journals (Sweden)

Fiorella Giusberti

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.

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

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.

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.

Helping medical students to acquire a deeper understanding of truth-telling.

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.

News, truth and crime: the Westray disaster and its aftermath

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 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?

Tang, Woung-Ru; Fang, Ji-Tseng; Fang, Chun-Kai; Fujimori, Maiko

2013-07-01

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.

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.

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

Science.gov (United States)

Gil, Gustavo; Savino, Giovanni; Piantini, Simone; Pierini, Marco

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.

Outcome: 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. Lessons learned: 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.

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

Science.gov (United States)

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

Truth, laws and the progress of science

Directory of Open Access Journals (Sweden)

Mauro Dorato

2011-06-01

Full Text Available In this paper I analyze the difficult question of the truth of mature scientific theories by tackling the problem of the truth of laws. 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.

What Justice for Rwanda? Gacaca versus Truth Commission?

OpenAIRE

Reuchamps, Min

2008-01-01

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...

Knowledge does not protect against illusory truth.

Fazio, Lisa K; Brashier, Nadia M; Payne, B Keith; Marsh, Elizabeth J

2015-10-01

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).

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.

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

Climate: the truth and the false

International Nuclear Information System (INIS)

Masson-Delmotte, V.

2011-01-01

Climate sciences have become extraordinary instruments for the media and the politicians. The climate debates regularly put forward the question of our knowledge: what do we know exactly, what can we assert, and of what are we doubtful? A subsidiary question would be: are scientists telling us the truth? For the scientific community, there is no doubt that human activities are modifying the Earth's atmosphere composition and that the surface temperature of the Earth has globally warmed up since the beginning of the 20. century. We live on a planet with a finite dimension: fossil resources are not forever and wastes are accumulating. Is the greenhouse effect already changing climate? Is it the only factor which will control the climate evolution? What would be the natural rhythm of climate? Are scientists capable to unravel the wheels of the climate machine? What is the situation of the climate change under way with respect to the turbulences of the past? What is an acceptable climate change? This book gives a clear answer to each of these questions as far as the answer is known. (J.S.)

Reference-free ground truth metric for metal artifact evaluation in CT images

International Nuclear Information System (INIS)

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.

Culture, Truth, and Science After Lacan.

Science.gov (United States)

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.

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.

THE RULE OF TRUTH AND “WHITE LIE” IN MODERN MEDICINE

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

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.

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.

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.

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.

Fuzzy logic of quasi-truth an algebraic treatment

CERN Document Server

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...

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.

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.

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.

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

Directory of Open Access Journals (Sweden)

Okun Oleg

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.

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.

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

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

Directory of Open Access Journals (Sweden)

Jan Bayer

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.

A Bridge to Reconciliation: A Critique of the Indian Residential School Truth Commission

Directory of Open Access Journals (Sweden)

Marc A. Flisfeder

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.

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.

Enhanced ASTER DEMs for Decadal Measurements of Glacier Elevation Changes

Science.gov (United States)

Girod, L.; Nuth, C.; Kääb, A.

2016-12-01

Elevation change data is critical to the understanding of a number of geophysical processes, including glaciers through the measurement their volume change. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) system on-board the Terra (EOS AM-1) satellite has been a unique source of systematic stereoscopic images covering the whole globe at 15m resolution and at a consistent quality for over 15 years. While satellite stereo sensors with significantly improved radiometric and spatial resolution are available today, the potential of ASTER data lies in its long consistent time series that is unrivaled, though not fully exploited for change analysis due to lack of data accuracy and precision. ASTER data are strongly affected by attitude jitter, mainly of approximately 4 and 30 km wavelength, and improving the generation of ASTER DEMs requires removal of this effect. We developed MMASTER, an improved method for ASTER DEM generation and implemented it in the open source photogrammetric library and software suite MicMac. The method relies on the computation of a rational polynomial coefficients (RPC) model and the detection and correction of cross-track sensor jitter in order to compute DEMs. Our sensor modeling does not require ground control points and thus potentially allows for automatic processing of large data volumes. When compared to ground truth data, we have assessed a ±5m accuracy in DEM differencing when using our processing method, improved from the ±30m when using the AST14DMO DEM product. We demonstrate and discuss this improved ASTER DEM quality for a number of glaciers in Greenland (See figure attached), Alaska, and Svalbard. The quality of our measurements promises to further unlock the underused potential of ASTER DEMs for glacier volume change time series on a global scale. The data produced by our method will thus help to better understand the response of glaciers to climate change and their influence on runoff and sea level.

An inconvenient truth; Une verite qui derange

Energy Technology Data Exchange (ETDEWEB)

Al, Gore

2007-01-15

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)

Reflection is required around the question of the respect of the right to the truth for people with cognitive disorders.

Validation of neural spike sorting algorithms without ground-truth information.

Science.gov (United States)

Barnett, Alex H; Magland, Jeremy F; Greengard, Leslie F

2016-05-01

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.

A Linguistic Truth-Valued Temporal Reasoning Formalism and Its Implementation

Science.gov (United States)

Lu, Zhirui; Liu, Jun; Augusto, Juan C.; Wang, Hui

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.

Geographic information system for fusion and analysis of high-resolution remote sensing and ground truth data

Freeman, Anthony; Way, Jo Bea; Dubois, Pascale; Leberl, Franz

1992-01-01

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

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

Science.gov (United States)

Jaarsma, Pier; Gelhaus, Petra; Welin, Stellan

2012-08-01

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'.

Being asked to tell an unpleasant truth about another person activates anterior insula and medial prefrontal cortex.

Science.gov (United States)

Littlefield, Melissa M; Dietz, Martin J; Fitzgerald, Des; Knudsen, Kasper J; Tonks, James

2015-01-01

"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.

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

Directory of Open Access Journals (Sweden)

Elena Maculan

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.

Davidson, Dualism, and Truth

Directory of Open Access Journals (Sweden)

Nathaniel Goldberg

2012-12-01

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.

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.

Methodology for building confidence measures

Science.gov (United States)

Bramson, Aaron L.

2004-04-01

This paper presents a generalized methodology for propagating known or estimated levels of individual source document truth reliability to determine the confidence level of a combined output. Initial document certainty levels are augmented by (i) combining the reliability measures of multiply sources, (ii) incorporating the truth reinforcement of related elements, and (iii) incorporating the importance of the individual elements for determining the probability of truth for the whole. The result is a measure of confidence in system output based on the establishing of links among the truth values of inputs. This methodology was developed for application to a multi-component situation awareness tool under development at the Air Force Research Laboratory in Rome, New York. Determining how improvements in data quality and the variety of documents collected affect the probability of a correct situational detection helps optimize the performance of the tool overall.

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.

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.

CONCEPT OF "TRUTH" IN THE NOVEL OF MIKHAIL BULGAKOV'S MASTER AND MARGARITA

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.

Chinese Children's Moral Evaluation of Lies and Truths-Roles of Context and Parental Individualism-Collectivism Tendencies.

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.

Full Text Available We investigate emerging mobile crowd sensing (MCS systems, in which new cloud-based platforms sequentially allocate homogenous sensing jobs to dynamically-arriving users with uncertain service qualities. 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.

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

Full Text Available I. We can talk about the crisis of the truth (in the meaning of the classical cor- respondence theory in the contemporary philosophy (of the 20th century. II. 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. IV. Therefore the truth understood as an epistemological category, the purpose of education and moral value, should be restored to our didactic and educational activities.

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.

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

Science.gov (United States)

Avci, Ercan

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.

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

Science.gov (United States)

Staver, John R.

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.

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.

Camera on Vessel: A Camera-Based System to Measure Change in Water Volume in a Drinking Glass

Directory of Open Access Journals (Sweden)

Idowu Ayoola

2015-09-01

Full Text Available A major problem related to chronic health is patients’ “compliance” with new lifestyle changes, medical prescriptions, recommendations, or restrictions. Heart-failure and hemodialysis patients are usually placed on fluid restrictions due to their hemodynamic status. A holistic approach to managing fluid imbalance will incorporate the monitoring of salt-water intake, body-fluid retention, and fluid excretion in order to provide effective intervention at an early stage. Such an approach creates a need to develop a smart device that can monitor the drinking activities of the patient. This paper employs an empirical approach to infer the real water level in a conically shapped glass and the volume difference due to changes in water level. The method uses a low-resolution miniaturized camera to obtain images using an Arduino microcontroller. The images are processed in MATLAB. Conventional segmentation techniques (such as a Sobel filter to obtain a binary image are applied to extract the level gradient, and an ellipsoidal fitting helps to estimate the size of the cup. The fitting (using least-squares criterion between derived measurements in pixel and the real measurements shows a low covariance between the estimated measurement and the mean. The correlation between the estimated results to ground truth produced a variation of 3% from the mean.

Interdependence versus Truth and Justice: Lessons from Reconciliation Processes in Maluku

Directory of Open Access Journals (Sweden)

Diah Kusumaningrum

2017-01-01

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.

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

Science.gov (United States)

de Pentheny O'Kelly, Clarissa; Urch, Catherine; Brown, Edwina A

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.

Measuring Soil Moisture in Skeletal Soils Using a COSMOS Rover

Science.gov (United States)

Medina, C.; Neely, H.; Desilets, D.; Mohanty, B.; Moore, G. W.

2017-12-01

The presence of coarse fragments directly influences the volumetric water content of the soil. Current surface soil moisture sensors often do not account for the presence of coarse fragments, and little research has been done to calibrate these sensors under such conditions. The cosmic-ray soil moisture observation system (COSMOS) rover is a passive, non-invasive surface soil moisture sensor with a footprint greater than 100 m. Despite its potential, the COSMOS rover has yet to be validated in skeletal soils. The goal of this study was to validate measurements of surface soil moisture as taken by a COSMOS rover on a Texas skeletal soil. Data was collected for two soils, a Marfla clay loam and Chinati-Boracho-Berrend association, in West Texas. Three levels of data were collected: 1) COSMOS surveys at three different soil moistures, 2) electrical conductivity surveys within those COSMOS surveys, and 3) ground-truth measurements. Surveys with the COSMOS rover covered an 8000-h area and were taken both after large rain events (>2") and a long dry period. Within the COSMOS surveys, the EM38-MK2 was used to estimate the spatial distribution of coarse fragments in the soil around two COSMOS points. Ground truth measurements included coarse fragment mass and volume, bulk density, and water content at 3 locations within each EM38 survey. Ground-truth measurements were weighted using EM38 data, and COSMOS measurements were validated by their distance from the samples. There was a decrease in water content as the percent volume of coarse fragment increased. COSMOS estimations responded to both changes in coarse fragment percent volume and the ground-truth volumetric water content. Further research will focus on creating digital soil maps using landform data and water content estimations from the COSMOS rover.

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.

2009-05-01

States and national organizations spend millions annually on antismoking campaigns aimed at youth. Much of the evidence for their effectiveness is based on cross-sectional studies. This study was designed to evaluate the effectiveness of a prominent national youth smoking-prevention campaign in the U.S. known as truth that was launched in February 2000. A nationally representative cohort of 8904 adolescents aged 12-17 years who were interviewed annually from 1997 to 2004 was analyzed in 2008. A quasi-experimental design was used to relate changes in smoking initiation to variable levels of exposure to antismoking messages over time and across 210 media markets in the U.S. A discrete-time hazard model was used to quantify the influence of media market delivery of TV commercials on smoking initiation, controlling for confounding influences. Based on the results of the hazard model, the number of youth nationally who were prevented from smoking from 2000 through 2004 was estimated. Exposure to the truth campaign is associated with a decreased risk of smoking initiation (relative risk=0.80, p=0.001). Through 2004, approximately 450,000 adolescents were prevented from trying smoking nationwide. Factors negatively associated with initiation include African-American race (relative risk=0.44, p<0.001), Hispanic ethnicity (relative risk=0.74, p<0.001), completing high school (relative risk=0.69, p<0.001), and living with both parents at baseline (OR=0.79, p<0.001). The current study strengthens the available evidence for antismoking campaigns as a viable strategy for preventing youth smoking.

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.

This paper explores the use of Boolean Truth Table modeling Method (BTTM) in the analysis of qualitative data. It is widely used in certain fields especially in the fields of electrical and electronic engineering. Our work focuses on the evaluation of power supply circuit reliability using (BTTM) which involves systematic attempts to falsify and identify hypotheses on the basis of truth tables constructed from qualitative data. Reliability parameters such as the system's failure rates for the power supply case study are estimated. All possible state combinations (operating and failed states) of the major components in the circuit were listed and their effects on overall system were studied

Full Text Available Through the audience research approach of in-depth interviews with users of the internet PTT Gossiping forum, this papers employs the concept of “politics of truth” to examine the “gossip” culture in the forum as well as the operation of truth/power politics within it. User interviews provide understandings of the meanings, operations, subject positions and social practices of the forum and how they interact with power politics in society. The gossip forum has expanded what gossip culture represents from collective imagination to social practices, renewing the perspectives derived from it, while engaging in a dialogue with the concept of politics of truth.

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

Science.gov (United States)

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.

Modeling multiple time series annotations as noisy distortions of the ground truth: An Expectation-Maximization approach.

Science.gov (United States)

Gupta, Rahul; Audhkhasi, Kartik; Jacokes, Zach; Rozga, Agata; Narayanan, Shrikanth

2018-01-01

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.

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.

Van Hecke, Wim; Leemans, Alexander; D'Agostino, Emiliano; De Backer, Steve; Vandervliet, Evert; Parizel, Paul M.; Sijbers, Jan

2008-03-01

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.

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

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

Science.gov (United States)

Press, Jacques

2006-04-01

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.

Truth and Credibility in Sincere Policy Analysis: Alternative Approaches for the Production of Policy-Relevant Knowledge.

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

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.

On Telling a Lie to Reveal the Truth: Mongrel

Directory of Open Access Journals (Sweden)

James Clinton Oleson

2017-07-01

Full Text Available South African author William Dicey’s 2016 collection of essays, Mongrel, operates as a literary prism, refracting and clarifying literary and sociological elements of life. The book’s six essays grapple with a sprawling range of subjects, including: the elusive distinction between fiction and non-fiction, literary footnotes, the endeavor of writing, the search for truth, the citizen’s search for community, the relevance of ethnicity in post-apartheid society, the perpetuation of socioeconomic disadvantage, the tragedy of criminal justice, and collective moral culpability for climate change. History, economics, and practical ethics underscore the entire collection, and exogenous sources such as Nabokov’s Pale Fire and Coetzee’s Disgrace can lend depth to the works. The essays of Mongrel can be understood as six discrete works, but they can also be understood as a meta-narrative that takes as its object the sociological search for restored community and the literary quest for authenticity.

Truth-telling, decision-making, and ethics among cancer patients in nursing practice in China.

Science.gov (United States)

Ling, Dong-Lan; Yu, Hong-Jing; Guo, Hui-Ling

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.

Improving the Quality of Satellite Imagery Based on Ground-Truth Data from Rain Gauge Stations

Directory of Open Access Journals (Sweden)

Ana F. Militino

2018-03-01

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.

On truth-telling and storytelling: Truth-seeking during research involving communities with an oral culture and a history of violent conflict

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.

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.

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

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

Directory of Open Access Journals (Sweden)

Judee K Burgoon

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.

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.

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...

Art and fiction are signals with indeterminate truth values.

Menninghaus et al. distinguish art from fiction, but no current arguments or data suggest that the concept of art can be meaningfully circumscribed. This is a problem for aesthetic psychology. I sketch a solution by rejecting the distinction: Unlike most animal communication, in which signals are either true or false, art and fiction consist of signals without determinate truth values.

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

Nonreference Medical Image Edge Map Measure

Directory of Open Access Journals (Sweden)

Karen Panetta

2014-01-01

Full Text Available Edge detection is a key step in medical image processing. It is widely used to extract features, perform segmentation, and further assist in diagnosis. A poor quality edge map can result in false alarms and misses in cancer detection algorithms. Therefore, it is necessary to have a reliable edge measure to assist in selecting the optimal edge map. Existing reference based edge measures require a ground truth edge map to evaluate the similarity between the generated edge map and the ground truth. However, the ground truth images are not available for medical images. Therefore, a nonreference edge measure is ideal for medical image processing applications. In this paper, a nonreference reconstruction based edge map evaluation (NREM is proposed. The theoretical basis is that a good edge map keeps the structure and details of the original image thus would yield a good reconstructed image. The NREM is based on comparing the similarity between the reconstructed image with the original image using this concept. The edge measure is used for selecting the optimal edge detection algorithm and optimal parameters for the algorithm. Experimental results show that the quantitative evaluations given by the edge measure have good correlations with human visual analysis.

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)

Politics of change: the discourses that inform organizational change and their capacity to silence.

Science.gov (United States)

McMillan, Kim

2016-09-01

Changes in healthcare organizations are inevitable and occurring at unprecedented rates. Such changes greatly impact nurses and their work, yet these experiences are rarely explored. Organizational change discourses remain grounded in perspectives that explore and explain systems, often not the people within them. Change processes in healthcare organizations informed by such organizational discourses validate only certain perspectives and forms of knowledge. This fosters exclusionary practices, limiting the capacity of certain individuals or groups of individuals to effectively contribute to change discourses and processes. The reliance on mainstream organizational discourses in healthcare organizations has left little room for the exploration of diverse perspectives on the subject of organizational change, particularly those of nurses. Michel Foucault's work challenges dominant discourse and suggest that strong reliance's on specific discourses effectively disqualify certain forms of knowledge. Foucault's writings on disqualified knowledge and parrhesia (truth telling and frank speech) facilitate the critical exploration of discourses that inform change in healthcare organizations and nurses capacities to contribute to organizational discourses. This paper explores the capacity of nurses to speak their truths within rapidly and continuously changing healthcare organizations when such changes are often driven by discourses not derived from nursing knowledge or experience. © 2016 John Wiley & Sons Ltd.

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.

Disclosing the truth: a dilemma between instilling hope and respecting patient autonomy in everyday clinical practice.

2013-12-20

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.

Autonomy versus absolute truth in comparative law on family status of the child

Directory of Open Access Journals (Sweden)

Kovaček-Stanić Gordana

2011-01-01

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.

Outdoor surface temperature measurement: ground truth or lie?

Science.gov (United States)

Skauli, Torbjorn

2004-08-01

Contact surface temperature measurement in the field is essential in trials of thermal imaging systems and camouflage, as well as for scene modeling studies. The accuracy of such measurements is challenged by environmental factors such as sun and wind, which induce temperature gradients around a surface sensor and lead to incorrect temperature readings. In this work, a simple method is used to test temperature sensors under conditions representative of a surface whose temperature is determined by heat exchange with the environment. The tested sensors are different types of thermocouples and platinum thermistors typically used in field trials, as well as digital temperature sensors. The results illustrate that the actual measurement errors can be much larger than the specified accuracy of the sensors. The measurement error typically scales with the difference between surface temperature and ambient air temperature. Unless proper care is taken, systematic errors can easily reach 10% of this temperature difference, which is often unacceptable. Reasonably accurate readings are obtained using a miniature platinum thermistor. Thermocouples can perform well on bare metal surfaces if the connection to the surface is highly conductive. It is pointed out that digital temperature sensors have many advantages for field trials use.

Telling the truth: Don DeLillo in an age of amnesia and redressDOI:10.5007/2175-8026.2010n59p176

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.

A new device for acquiring ground truth on the absorption of light by turbid waters

Science.gov (United States)

Klemas, V. (Principal Investigator); Srna, R.; Treasure, W.

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.

Truths and fallacies concerning radiation and its effects

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

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

Science.gov (United States)

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.

Ground truth methods for optical cross-section modeling of biological aerosols

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.

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.

2017-01-01

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

On the construction of reality and truth. Towards an epistemology of community social psychology.

Science.gov (United States)

Montero, Maritza

2002-08-01

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.

2017-02-15

Recently, a new measurement theory based on truth values was proposed by Nagata and Nakamura [Int. J. Theor. Phys. 55, 3616 (2016)], that is, a theory where the results of measurements are either 0 or 1. The standard measurement theory accepts a hidden variable model for a single Pauli observable. Hence, we can introduce a classical probability space for the measurement theory in this particular case. Additionally, we discuss in the present contribution the fact that projective measurement theories (the results of which are either +1 or −1) imply the Bell, Kochen, and Specker (BKS) paradox for a single Pauli observable. To justify our assertion, we present the BKS theorem in almost all the two-dimensional states by using a projective measurement theory. As an example, we present the BKS theorem in two-dimensions with white noise. Our discussion provides new insight into the quantum measurement problem by using this measurement theory based on the truth values.

Populism, Exclusion, Post-truth. Some Conceptual Caveats

Science.gov (United States)

De Cleen, Benjamin

2018-01-01

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

Truth Telling in the Setting of Cultural Differences and Incurable Pediatric Illness

Rosenberg, Abby R.; Starks, Helene; Unguru, Yoram; Feudtner, Chris; Diekema, Douglas

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

The Ugly Truth About Ourselves and Our Robot Creations: The Problem of Bias and Social Inequity.

Science.gov (United States)

Howard, Ayanna; Borenstein, Jason

2017-09-21

Recently, there has been an upsurge of attention focused on bias and its impact on specialized artificial intelligence (AI) applications. Allegations of racism and sexism have permeated the conversation as stories surface about search engines delivering job postings for well-paying technical jobs to men and not women, or providing arrest mugshots when keywords such as "black teenagers" are entered. Learning algorithms are evolving; they are often created from parsing through large datasets of online information while having truth labels bestowed on them by crowd-sourced masses. These specialized AI algorithms have been liberated from the minds of researchers and startups, and released onto the public. Yet intelligent though they may be, these algorithms maintain some of the same biases that permeate society. They find patterns within datasets that reflect implicit biases and, in so doing, emphasize and reinforce these biases as global truth. This paper describes specific examples of how bias has infused itself into current AI and robotic systems, and how it may affect the future design of such systems. More specifically, we draw attention to how bias may affect the functioning of (1) a robot peacekeeper, (2) a self-driving car, and (3) a medical robot. We conclude with an overview of measures that could be taken to mitigate or halt bias from permeating robotic technology.

Civil history and poetry, certainty and truth in Francis Bacon

Directory of Open Access Journals (Sweden)

Silvia Manzo

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.

Registered Report: Measuring Unconscious Deception Detection by Skin Temperature

Directory of Open Access Journals (Sweden)

Anna Elisabeth Van 't Veer

2014-05-01

Full Text Available Findings from the deception detection literature suggest that although people are not skilled in consciously detecting a liar, they may intuit that something about the person telling a lie is off. In the current proposal, we argue that observing a liar influences the observer’s physiology even though the observer may not be consciously aware of being lied to (i.e., the observers’ direct deception judgment does not accurately differentiate between liars and truth-tellers. To test this hypothesis, participants’ finger temperature will be measured while they watch videos of persons who are either honest or dishonest about their identity. We hypothesize that skin temperature will be lower when observing a liar than when observing a truth-teller. Additionally, we test whether perceiving a liar influences finger skin temperature differently when an individual is, or is not, alerted to the possibility of deceit. We do this by varying participants’ awareness of the fact that they might be lied to. Next to measuring physiological responses to liars and truth-tellers, self-reported direct and indirect veracity judgments (i.e., trustworthiness and liking of the target persons will be assessed. We hypothesize that indirect veracity judgments will better distinguish between liars and truth-tellers than direct veracity judgments.

Full Text Available The article is focused on the document published in 2014 by the Pontifical Biblical Commission and called: The Inspiration and Truth of Sacred Scripture. The Word that comes from God and speaks of God for the salvation of the world. The purpose of publishing was to reach the priests, the people studying the Bible as well as the laity. 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. Besides we always have to include the genre and style of the ancient authors. This document can have amazing impact on the pastoral work, helping people to get interested in the Bible and to find the answers for many questions they have about it.

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

Science.gov (United States)

Martin, Clancy

2014-10-01

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.

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

Energy Technology Data Exchange (ETDEWEB)

Bradonjic, Milan [Los Alamos National Laboratory

2009-01-01

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.

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

Directory of Open Access Journals (Sweden)

Signe Larsen

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.

Truth, Art, and the “New Sensuousness”: Understanding Heidegger’s Metaphysical Reading of Nietzsche

Directory of Open Access Journals (Sweden)

James Magrini

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.

The use of the truth and deception in dementia care amongst general hospital staff.

Turner, Alex; Eccles, Fiona; Keady, John; Simpson, Jane; Elvish, Ruth

2017-08-01

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.

Notions such as "truth" or "correspondence to the objective world" play no role in explanatory accounts of perception.

Science.gov (United States)

Mausfeld, Rainer

2015-12-01

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.

Community detection algorithm evaluation with ground-truth data

Science.gov (United States)

Jebabli, Malek; Cherifi, Hocine; Cherifi, Chantal; Hamouda, Atef

2018-02-01

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.

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

Subjetividade e verdade no último Foucault Subjectivity and truth in the late Foucault

Full Text Available A constituição do sujeito na investigação do último Foucault geralmente é conhecida pela perspectiva de sua estética da existência. Tal abordagem deve-se sobremaneira à leitura dos dois últimos volumes de Histoire de la sexualité (1984. No entanto, o presente artigo aponta que nos cursos no Collège de France intitulados Subjectivité et verité (1981 e L'herméneutique du sujet (1982 outra leitura pode ser elaborada. A relação entre subjetividade e verdade evidencia-se como central em seu pensamento e seus desdobramentos são apresentados a partir das diferenças estabelecidas entre filosofia e espiritualidade, das articulações entre cuidado de si e conhecimento de si, conhecimentos úteis e inúteis, cuidado de si e conversão a si, ascese e verdade.The constitution of the subject in the investigation of the late Foucault is generally dealt with through the perspective of his aesthetics of existence. Such approach is mainly due to the reading of the two last volumes of The History of Sexuality (1984. However, the present article points out that in his Collège de France courses entitled Subjectivity and Truth (1981 and The Hermeneutics of the Subject (1982, a different reading can be elaborated. The relation between subjectivity and truth is evidently central in his thinking and its developments are presented from the differences established between philosophy and spirituality, from the articulations between care of the self and knowledge of the self, useful knowledge and useless knowledge, care of the self and conversion to the self, asceticism and truth.

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.

Right to Truth: Dissapeared students in Ayotzinapa, Mexico

Full Text Available The disappearance of the 43 students Ayotzinapa in Iguala Guerrero, will remain in the history of Mexico as one of the most serious incidents of violation of human rights carried out by organized crime in complicity with public servants. The official version of events does not answer many questions of the family, nor it does answer the questions of the society as a whole. Ensure the right to truth for victims, as well as for the national and international community, must be assumed by the Mexican State as an obligation which complies fully with the necessary guarantees that international principles apply to enforced disappearances, both to repair damage, and to prevent its recurrence.

Knowledge of the outcomes measured by these trials is vital not only for the interpretation and application of the work done to date, but also to inform future research in this expanding area of endeavour and to assist in collation of results in systematic reviews and meta-analyses. The objective of this review was to identify methods used to measure change in the clinical practices of health professionals following an intervention aimed at increasing the uptake of evidence into practice. All published trials included in a recent, comprehensive Health Technology Assessment of interventions to implement clinical practice guidelines and change clinical practice (n = 228) formed the sample for this study. Using a standardised data extraction form, one reviewer (SH), extracted the relevant information from the methods and/or results sections of the trials. Measures of a change of health practitioner behaviour were the most common, with 88.8% of trials using these as outcome measures. Measures that assessed change at a patient level, either actual measures of change or surrogate measures of change, were used in 28.8% and 36.7% of studies (respectively). Health practitioners' knowledge and attitudes were assessed in 22.8% of the studies and changes at an organisational level were assessed in 17.6%.

Assessment of MTI Water Temperature Retrievals with Ground Truth from the Comanche Peak Steam Electric Station Cooling Lake

International Nuclear Information System (INIS)

Kurzeja, R.J.

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

First- and third-party ground truth for key frame extraction from consumer video clips

Science.gov (United States)

Costello, Kathleen; Luo, Jiebo

2007-02-01

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.

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.

Cinematic climate change, a promising perspective on climate change communication.

2015-10-01

Previous research findings display that after having seen popular climate change films, people became more concerned, more motivated and more aware of climate change, but changes in behaviors were short-term. This article performs a meta-analysis of three popular climate change films, The Day after Tomorrow (2005), An Inconvenient Truth (2006), and The Age of Stupid (2009), drawing on research in social psychology, human agency, and media effect theory in order to formulate a rationale about how mass media communication shapes our everyday life experience. This article highlights the factors with which science blends in the reception of the three climate change films and expands the range of options considered in order to encourage people to engage in climate change mitigation actions. © The Author(s) 2014.

Herbal medicines: old and new concepts, truths and misunderstandings

Directory of Open Access Journals (Sweden)

Fabio Carmona

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.

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

Science.gov (United States)

Rosenberg, Abby R; Starks, Helene; Unguru, Yoram; Feudtner, Chris; Diekema, Douglas

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.

The issue of climate change from the perspectives of climate change scientists and climate policy makers is discussed using results from two survey questionnaires. Emphasis is given to the German context. Included is the self assessment of the state of the art of the climate sciences and the importance assigned to different sources of information by policy makers. Conclusions indicate that policy makers rely on a number of sources other than the direct results of science, and have assigned a greater sense of urgency to the issue of climate change than have scientists. (orig.) [German] Auf Grundlage der Ergebnisse zweier Fragebogenaktionen wird diskutiert, wie sich die Problematik von Klimaveraenderungen aus der Perspektive von Klimaforschern und aus der Perspektive von mit Klimapolitik befassten Entscheidungstraegern darstellt. Die Betonung liegt auf den Verhaeltnissen in Deutschland. Eingeschlossen ist eine Einschaetzung des aktuellen Standes der Klimaforschung durch die Wissenschaftler selbst sowie der Bedeutung, welche von politischen Entscheidungstraegern verschiedenen Informationsquellen beigemessen wird. Es zeigt sich, dass sich politische Entscheidungstraeger auf zahlreiche Informationsquellen verlassen, die nur indirekt die Resultate der Klimaforschung wiedergeben und, dass dieser Personenkreis das Problem der Klimaveraenderungen als draengender ansieht als die Wissenschaftler selbst.

Full Text Available Hammond (1996 argued that much of the research in the field of judgment and decision making (JDM can be categorized as focused on either coherence or correspondence (CandC and that, in order to understand the findings of the field, one needs to understand the differences between these two criteria. extit{Hammond's claim} is that conclusions about the competence of judgments and decisions will depend upon the selection of coherence or correspondence as the criterion (Hammond, 2008. First, I provide an overview of the terms coherence and correspondence (CandC as philosophical theories of truth and relate them to the field of JDM. Second, I provide an example of Hammond's claim by examining literature on base rate neglect. Third, I examine Hammond's claim as it applies to the broader field of JDM. Fourth, I critique Hammond's claim and suggest that refinements to the CandC distinction are needed. Specifically, the CandC distinction 1 is more accurately applied to criteria than to researchers, 2 should be refined to include two important types of coherence (inter and intrapersonal coherence and 3 neglects the third philosophical theory of truth, pragmatism. Pragmatism, as a class of criteria in JDM, is defined as goal attainment. In order to provide the most complete assessment of human judgment possible, and understand different findings in the field of JDM, all three criteria should be considered.

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

Science.gov (United States)

Park, Junghyun; Hayward, Chris; Stump, Brian W.

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.

"Angels & Demons" - Distinguishing truth from fiction

CERN Multimedia

2005-01-01

Dan Brown's best-selling novel "Angels & Demons" was published in French on 2 March. A web page on CERN's public site is dedicated to separating truth from fiction in this novel. After the extraordinary success of Dan Brown's "Da Vinci Code", one of his earlier novels "Angels & Demons", published in 2000, has now become a best seller and has generated a flood of questions about CERN. This detective story is about a secret society, the Illuminati, who wish to destroy the Vatican with an antimatter bomb stolen from - wait for it - CERN! Inevitably, CERN has been bombarded with calls about the technologies described in the novel that are supposed to be under development in the Laboratory. The Press Office has always explained that, even if the novel appears to be very informative, it is in fact a mixture of fact and fiction. For instance, according to the novel CERN is supposed to own a plane that can cover the distance between Massachusetts in the United States and Switzerland in just over an hour! ...

Truth or lie--some ethical dilemmas in the communication of a severe diagnosis.

Science.gov (United States)

Gramma, Rodica; Parvu, Andrada; Enache, Angela; Roman, G; Ioan, Beatrice

2013-01-01

Informing the patient about his disease is a very important issue in the medical practice, thus communication becomes imperative in healthcare services. Communicating the diagnosis of a pathology that doesn't bear any imminent risk for life is a common procedure for physicians. However, the situation changes drastically in the case of a severe diagnosis or a hopeless prognosis, with terminally ill patients. In this article the authors proceed to a critical analysis of the dilemma of communication or non-communication of a severe diagnosis. The problem of communicating a severe diagnosis is described from a philosophical perspective (in terms of three fundamental ethical theories: Aristotle's theory of virtue, Kant's ethical theory and Bentham and Mill's moral theories). At the same time, certain physiological and medical approaches are presented. In order to avoid any communication conflict, especially considering the particular situation of the seriously ill patient in the context of the contemporary medical activities, the authors propose the debating of two opposing approaches: "the sacred lie principle" and "the justified medical truth" in the physician--patient relation.

Full Text Available The case of former Yugoslavia and its successors is specific and a bit different from the other post-conflict societies. First, retributive model of justice is carried out, or it should be carried out, before the International Criminal Tribunal in the Hague. The question is how to start the process of searching for the truth and reconciliation inside and between societies, groups and individuals in newly established countries. There is no such a model in the world, like these in South Africa and some countries in Latin America, which can be applied here, because in this case we are talking about five states, from which at least three were in the war. Also, the character of these conflicts covers the diapason from international conflicts to internal aggression and civil war.

2017-02-12

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. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Stop the Spam! Conference Ethics and Decoding the Subtext in Post-Truth Science. What Would Denis Diderot Say?

Özdemir, Vural; Dandara, Collet; Hekim, Nezih; Birch, Kean; Springer, Simon; Kunej, Tanja; Endrenyi, Laszlo

2017-11-01

Science and its practice always had a subtext, subject to influence by scientists', funders', and other innovation actors' values and assumptions. The recent emergence of post-truth, authoritarian and populist penchants, in both developed and developing countries, has further blurred the already fluid boundaries between material scientific facts and their social construction/shaping by scientific subtext, human values, powers, and hegemony. While there are certain checks, balances, and oversight mechanisms for publication ethics, other pillars of science communication, most notably, scientific conferences and their governance, are ill prepared for post-truth science. Worrisomely, the proliferation of spam conferences is a major cause for concern for integrative biology and postgenomic science. The current gaps in conference ethics are important beyond science communication because conferences help build legitimacy of emerging technologies and frontiers of science and, thus, bestows upon the organizers, funders, enlisted scientific advisors, speakers, among others, power, which in turn needs to be checked. Denis Diderot (1713-1784), a prominent intellectual during the Enlightenment period, has aptly observed that the very act of organizing brings about power, influence, and control. If the subtext of conference practices is left unchecked, it can pave the way for hegemony, and yet more volatile and violent authoritarian governance systems in science and society. This begs for innovative solutions to increase accountability, resilience, and capacity of technology experts and scientists to discern and decode the subtext in science and its communication in the current post-truth world. We propose that the existing undergraduate and graduate programs in life and physical sciences and medicine could be redesigned to include a rotation for exposure to and training in political science.

We assessed to what extent relative changes in net magnetization could be measured with the low field (0.043 T) MR imager. By the procedure to stabilize the whole MR imager hardware, we could measure the minute relative changes of the net magnetization (less than 1%) from the forearm presumably related to blood volume change. This method may be useful to measure physiological changes of blood volume in various human tissues though we need further development of hardware to measure minute relative changes in MR signal intensity with small volume selection.

Measurement and quasi-states in quantum mechanics

International Nuclear Information System (INIS)

Harper, C.D.

1987-01-01

Part of the task of quantum logic is to account for the collapse of the state vector during measurement. A difficulty in this is that it is not obvious how to describe measurement quantum mechanically as the interaction of two or more systems; interacting quantum-mechanical systems do not possess states, so their states cannot collapse. This dissertation shows that component systems of a composite system possess families of state-like vectors. These are the quasi-projections of the state vector of the composite system, each associated with a family of commutable observables. Often these quasi-projections cluster so closely around a quasi-state that they are practically indistinguishable from it. A description of measurement based on quasi-projections reveals the apparent collapse of the state vector during measurement to be illusory. The continuous evolution of the state of the composite system give rise to abrupt changes in the quasi-projections which make it appear that the state has changed. The quasi-projections cease to cluster near one quasi-state, are momentarily scattered, and then cluster again near another quasi-state. The concept of quasi-projection is also used to generalize the quantum logic of Birkhoff and von Neumann in such a fashion that a proposition can always be assigned a truth value

Nuclear energy at a moment of truth. Six reasons behind the case for nuclear power

International Nuclear Information System (INIS)

Ritch, J. III

2002-01-01

Through the years, the simple word 'nuclear' has become the focal point for a seemingly endless controversy, filled with passions and ideologies that sprang originally from a rational fear of nuclear war - but grew into an emotional, and now somewhat institutionalised, standoff that plagues public discourse as to how the world's nations can best meet their energy needs in the 21st century. Along the way, the very idea of nuclear energy became a political and psychological surrogate. Scepticism about government, distrust of large corporations, worry over toxic industrial effluents, a subconscious fear of cataclysm - all these real feelings and fears are crystallized, for many people, in a vague concept called 'the nuclear industry'. The subject of this presentation is that this is an idea whose time has come: that nuclear energy, a half century after its inception, has reached a moment of truth, in no less than six important respects: first, the technology has come of age; second, on a national level, key issues affecting nuclear energy will soon demand decision; third, fossil supplies may simply be inadequate to meet world energy needs; fourth, the valuable uses of nuclear power will soon multiply; fifth, and of profound importance, a massive shift toward nuclear power is now environmentally indispensable; sixth, this moment of truth for nuclear power requires a telling of the truth. Given the urgent need for public awareness and political decision, those able to do so must now make the case for nuclear energy - forcefully, without apology or equivocation, and with persuasive effect. A great deal depends on developing the wisdom and will to exploit nuclear technology to full benefit

Calibration of Smartphone-Based Weather Measurements Using Pairwise Gossip.

Accurate and reliable daily global weather reports are necessary for weather forecasting and climate analysis. However, the availability of these reports continues to decline due to the lack of economic support and policies in maintaining ground weather measurement systems from where these reports are obtained. Thus, to mitigate data scarcity, it is required to utilize weather information from existing sensors and built-in smartphone sensors. However, as smartphone usage often varies according to human activity, it is difficult to obtain accurate measurement data. In this paper, we present a heuristic-based pairwise gossip algorithm that will calibrate smartphone-based pressure sensors with respect to fixed weather stations as our referential ground truth. Based on actual measurements, we have verified that smartphone-based readings are unstable when observed during movement. Using our calibration algorithm on actual smartphone-based pressure readings, the updated values were significantly closer to the ground truth values.

According to the principle of the uniqueness of truth, there should be only one truth, namely law of conservation of energy, in the area of Newton Mechanics. Through the example of free falling body, according to the neutrosophic principle considering neutralities (the small ball is falling to the middle positions), this paper derives the original Newton's second law and the original law of gravity respectively by using the law of conservation of energy.

Pharny D. Chrysler-Fox

2014-09-01

Research purpose: The aim of the study was to explore and describe changing domains within human capital management to be managed and measured. Motivation for the study: The motivation was to advance the understanding of changing measurement domains to aid practitioners to manage and measure the contribution of the human resource function and employees, in order to unlock and add value and ultimately contribute to the success of an organisation. Research design, approach and method: Unstructured, in-depth interview data of purposively selected cases from a selected panel of human resource practitioners specialising in human capital measurement was thematically analysed in this exploratory-descriptive investigation. Main findings: Findings suggested that seven domains should be managed and measured. These domains highlight new areas of impact and levels of management. In addition, crossdomain relationships in measurement allow for an understanding of the impact and potential value on which to capitalise. Practical/managerial implications: New domains to manage and measure focus the attention of practitioners beyond the transactional performance management paradigm to a transformational approach to influence the business strategy. Higher education institutions need to develop students’ cognitive skills to facilitate systems thinking. Contribution: This study suggests a new approach to managing and measuring the human capital function and the workforce.

The Nuclear Waste Discourse in Malaa - a Truth-Seeking Practice

Energy Technology Data Exchange (ETDEWEB)

Sjoelander, Annika [Umeaa Univ. (Sweden). Dept. of Culture and Media

2003-10-01

Malaa was the second municipality in Sweden that volunteered to allow the nuclear industry (SKB) to conduct a feasibility study of the possibility of final disposal of high-level radioactive waste in their area. After five years of examinations and discussions in the community, a local referendum was held which resulted in a negative response for further investigations within the municipality (44 % pro and 54% con). The importance and impact of local acceptance in nuclear waste management is clearly illustrated in the Malaa case. Prior to the referendum, all the key stakeholder groups tried their best to influence the outcome of the process through writing letters to the editor in the local newspaper, holding information meetings, consulting experts, et cetera. In this paper some main results from a longitudinal case study of the opinion formation process in Malaa are presented and discussed. Text and content analysis of the mass media coverage bas been undertaken as well as interviews with central stakeholders and opinion leaders through-out the whole process. The research has been framed by Michel Foucault's discourse theory, which is briefly introduced in the paper. In general, the nuclear waste discourse in Malaa can be summarised as an expression of the modem culture's strong desire for truth. The importance of scientific knowledge and expert opinions is, for example, emphasised a lot. All actors involved in the discourse constantly stated that there is a need for scientists and experts, because they are somehow viewed as truth tellers. But, at the same time, because the 'truth tellers' in the end didn't succeed in satisfying the expressed needs to deliver clear definitive answers, a lot of frustration was created.

Nothing but the truth: self-disclosure, self-revelation, and the persona of the analyst.

Science.gov (United States)

Levine, Susan S

2007-01-01

The question of the analyst's self-disclosure and self-revelation inhabits every moment of every psychoanalytic treatment. All self-disclosures and revelations, however, are not equivalent, and differentiating among them allows us to define a construct that can be called the analytic persona. Analysts already rely on an unarticulated concept of an analytic persona that guides them, for instance, as they decide what constitutes appropriate boundaries. Clinical examples illustrate how self-disclosures and revelations from within and without the analytic persona feel different, for both patient and analyst. The analyst plays a specific role for each patient and is both purposefully and unconsciously different in this context than in other settings. To a great degree, the self is a relational phenomenon. Our ethics call for us to tell nothing but the truth and simultaneously for us not to tell the whole truth. The unarticulated working concept of an analytic persona that many analysts have refers to the self we step out of at the close of each session and the self we step into as the patient enters the room. Attitudes toward self-disclosure and self-revelation can be considered reflections of how we conceptualize this persona.

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.

Gooch, B.G.

1987-01-01

This article leads the reader through the process of developing human potential by examining the assumption that development and change are synonymous concepts, and that many basic assumptions held regarding human reaction to change are false. If trainees proceed down the path filled with false premises, their task of improving performance is made more difficult. After resolution of basic truths concerning the nature of change, the article examines the process of creating a desire within individuals that will lead beyond motivation to activation. The article attempts to identify and discuss factors that are important to creating within individuals the desire to improve their performance

SafePub: A Truthful Data Anonymization Algorithm With Strong Privacy Guarantees

Directory of Open Access Journals (Sweden)

Bild Raffael

2018-01-01

Full Text Available Methods for privacy-preserving data publishing and analysis trade off privacy risks for individuals against the quality of output data. In this article, we present a data publishing algorithm that satisfies the differential privacy model. The transformations performed are truthful, which means that the algorithm does not perturb input data or generate synthetic output data. Instead, records are randomly drawn from the input dataset and the uniqueness of their features is reduced. This also offers an intuitive notion of privacy protection. Moreover, the approach is generic, as it can be parameterized with different objective functions to optimize its output towards different applications. We show this by integrating six well-known data quality models. We present an extensive analytical and experimental evaluation and a comparison with prior work. The results show that our algorithm is the first practical implementation of the described approach and that it can be used with reasonable privacy parameters resulting in high degrees of protection. Moreover, when parameterizing the generic method with an objective function quantifying the suitability of data for building statistical classifiers, we measured prediction accuracies that compare very well with results obtained using state-of-the-art differentially private classification algorithms.

What is the Point? Ethics, Truth and the Tractatus

DEFF Research Database (Denmark)

Christensen, Anne-Marie Søndergaard

2007-01-01

  In this paper, my major concern is to place the ethical remarks of Ludwig Wittgenstein's Tractatus within a wider discussion in moral philosophy. In the first part of the paper, I sketch a reading of the Tractatus that brings out a particular feature of ethics, namely the fact that ethical...... discourse is shaped by both subjective and objective concerns. Moving on, I unfold the subjective side of ethics by drawing on Stanley Cavell's notion of the point of an utterance, while the objective side will be presented via Diamond's writing on the importance of truth in ethics. My goal is to argue...

In this paper we consider the minimum cost spanning tree model. We assume that a central planner aims at implementing a minimum cost spanning tree not knowing the true link costs. The central planner sets up a game where agents announce link costs, a tree is chosen and costs are allocated according...... to the rules of the game. We characterize ways of allocating costs such that true announcements constitute Nash equilibria both in case of full and incomplete information. In particular, we find that the Shapley rule based on the irreducible cost matrix is consistent with truthful announcements while a series...

Truth, Representation and Interpretation: The Popper Case

Directory of Open Access Journals (Sweden)

Gerard Stan

2009-06-01

Full Text Available The aim of this study is to determine several points of reference regarding the way in which Karl Popper built up his philosophical discourse. I locate two specific ways in which Popper interpreted and used ideas belonging to other philosophers. Thus I distinguish in Popper between a projective hermeneutics (where the author uses a thesis that forms a part of his own philosophy in order to reconstruct and understand the ideas of another philosopher and anideological hermeneutics (where he uses a statement expressing an interest of the community whereof he is a member in order to interpret and reconstruct the text of another philosopher. In so doing I also highlight the considerable asymmetry between a representationalist hermeneutics, and a projective and, respectively, an ideological one. Whereas in the first case the interpreter wishes to unveil a truth about the philosophical text, in the other two he israther expressing a desire to talk about himself, his own beliefs and convictions, or about the beliefs of his community of reference.

In search of truth: the regulatory necessity of validation

International Nuclear Information System (INIS)

Niederer, U.

1991-01-01

A look at modern ideas of how scientific truth is achieved shows that theories are not really proved but accepted by a consensus of the experts, borne out by often repeated experience showing a theory to work well. In the same sense acceptability of models in waste disposal is mostly based on consensus. To obtain consensus of the relevant experts, including regulators, all models which considerably influence the results of a safety assessment have to be validated. This is particularly important for the models of geospheric migration because scientific experience with the deep underground is scarce. Validation plays a special role in public acceptance where regulators and other groups, which act as intermediaries between the public and the project manager, have to be convinced that all the relevant models are correct

Truth or meaning: Ricoeur versus Frei on biblical narrative

Directory of Open Access Journals (Sweden)

Gary L. Comstock

1989-01-01

Full Text Available Truth or meaning: Ricoeur versus Frei on biblical narrative Of the theologians and philosophers now writing on biblical narrative, Hans Frei and Paul Ricoeur are probably the most prominent. It is significant that their views converge on important issues. Both are uncomfortable with hermeneutic theories that convert the text into an abstract philosophical system, an ideal typological structure, or a mere occasion for existential decision. Frei and Ricoeur seem knit together in a common enterprise; they appear to be building a single narrative theology. I argue that the appearance of symmetry is an illusion. There is a fundamental conflict between the ‘pure narrativism’ of Frei and the ‘impure narrativism’ of Ricoeur. I give reasons for thinking that Ricoeur’s is the stronger position.

Illusion and betrayal
The city, the poets, or an ethics of truths?

Directory of Open Access Journals (Sweden)

Igor Stramignoni

2011-04-01

Full Text Available A nagging feeling of great expectations turned sour is in the air, at least at this end of the globe. The illusion appears to have been twofold. Those liberals who after the Cold War had imagined finally to see the Western city win over competing forms of self-regulation, self-reproduction, and homeostasis can no longer fail to see how, by the time the twenty-first century has commenced, democracy and the rule of law, the West's own blueprint for living together, have lost some of their lustre, when they have not been bluntly rejected. Those amongst the poets who, by contrast, had argued all along that another world was possible or, alternatively, that democracy and the rule of law could at most be promised or tendered rather than fully achieved or imposed, sometimes today worry whether in the process they may not have become somewhat problematically if unwittingly fixated with what in the age of mass culture and information technology some argue might be a potentially self-defeating aesthetics of the Other. Alain Badiou's Platonism of the multiple and, specifically, his ethics of truths invite us to consider whether the widespread sense of disappointment and closure which follow from such an unsatisfactory situation should not be grasped as a figure of nihilism, specifically as a figure of 'betrayal', and whether, on the other hand, what is required may not be discernment, courage, and caution and to remain alert to the possible occurrence of new signal events. Thus to a poetics of illusion and of consequent disappointment Badiou prefers an ethics of truths which starts from the obvious existence of certain generic truths and yet is never closed-off to the invention of new ones. As presented, Badiou's ethical proposal is far from being fully developed and it is bound to be contentious. And yet it does contribute to a unique and powerful critique of current events as they ceaselessly appear on the horizon of a more interconnected world

Biometric correspondence between reface computerized facial approximations and CT-derived ground truth skin surface models objectively examined using an automated facial recognition system.

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.

Measurement of change in health status with Rasch models.

2015-02-07

The traditional approach to the measurement of change presents important drawbacks (no information at individual level, ordinal scores, variance of the measurement instrument across time points), which Rasch models overcome. The article aims to illustrate the features of the measurement of change with Rasch models. To illustrate the measurement of change using Rasch models, the quantitative data of a longitudinal study of heart-surgery patients (N = 98) were used. The scale "Perception of Positive Change" was used as an example of measurement instrument. All patients underwent cardiac rehabilitation, individual psychological intervention, and educational intervention. Nineteen patients also attended progressive muscle relaxation group trainings. The scale was administered before and after the interventions. Three Rasch approaches were used. Two separate analyses were run on the data from the two time points to test the invariance of the instrument. An analysis was run on the stacked data from both time points to measure change in a common frame of reference. Results of the latter analysis were compared with those of an analysis that removed the influence of local dependency on patient measures. Statistics t, χ(2) and F were used for comparing the patient and item measures estimated in the Rasch analyses (a-priori α = .05). Infit, Outfit, R and item Strata were used for investigating Rasch model fit, reliability, and validity of the instrument. Data of all 98 patients were included in the analyses. The instrument was reliable, valid, and substantively unidimensional (Infit, Outfit instrument occurred across the two time, which prevented the use of the two separate analyses to unambiguously measure change. Local dependency had a negligible effect on patient measures (p ≥ .8674). Thirteen patients improved, whereas 3 worsened.

Measuring Regional Changes in Damaged Tendon

Science.gov (United States)

Frisch, Catherine Kayt Vincent

Mechanical properties of tendon predict tendon health and function, but measuring these properties in vivo is difficult. An ultrasound-based (US) analysis technique called acoustoelastography (AE) uses load-dependent changes in the reflected US signal to estimate tissue stiffness non-invasively. This thesis explores whether AE can provide information about stiffness alteration resulting from tendon tears both ex vivo and in vivo. An ex vivo ovine infraspinatus tendon model suggests that the relative load transmitted by the different tendon layers transmit different fractions of the load and that ultrasound echo intensity change during cyclic loading decreases, becoming less consistent once the tendon is torn. An in vivo human tibialis anterior tendon model using electrically stimulated twitch contractions investigated the feasibility of measuring the effect in vivo. Four of the five subjects showed the expected change and that the muscle contraction times calculated using the average grayscale echo intensity change compared favorably with the times calculated based on the force data. Finally an AE pilot study with patients who had rotator cuff tendon tears found that controlling the applied load and the US view of the system will be crucial to a successful in vivo study.

Outline of a Theory of Truth as Correctness for Semantic Information

2009-11-01

Full Text Available The article develops a correctness theory of truth (CTT for semantic information. After the introduction, in section two, semantic information is shown to be translatable into propositional semantic information (i. In section three, i is polarised into a query (Q and a result (R, qualified by a specific context, a level of abstraction and a purpose. This polarization is normalised in section four, where [Q + R] is transformed into a Boolean question and its relative yes/no answer [Q + A]. This completes the reduction of the truth of i to the correctness of A. In sections five and six, it is argued that (1 A is the correct answer to Q if and only if (2 A correctly saturates (in a Fregean sense Q by verifying and validating it (in the computer science’s sense of “verification” and “validation”; that (2 is the case if and only if (3 [Q + A] generates an adequate model (m of the relevant system (s identified by Q; that (3 is the case if and only if (4 m is a proxy of s (in the computer science’s sense of “proxy” and (5 proximal access to m commutes with the distal access to s (in the category theory’s sense of “commutation”; and that (5 is the case if and only if (6 reading/writing (accessing, in the computer science’s technical sense of the term m enables one to read/write (access s.

Taking Exception. Reduced mortality leads to population growth: an inconvenient truth.

Science.gov (United States)

Shelton, James D

2014-05-01

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.

Measuring Historical Coastal Change using GIS and the Change Polygon Approach

Science.gov (United States)

Smith, M.J.; Cromley, R.G.

2012-01-01

This study compares two automated approaches, the transect-from-baseline technique and a new change polygon method, for quantifying historical coastal change over time. The study shows that the transect-from-baseline technique is complicated by choice of a proper baseline as well as generating transects that intersect with each other rather than with the nearest shoreline. The change polygon method captures the full spatial difference between the positions of the two shorelines and average coastal change is the defined as the ratio of the net area divided by the shoreline length. Although then change polygon method is sensitive to the definition and measurement of shoreline length, the results are more invariant to parameter changes than the transect-from-baseline method, suggesting that the change polygon technique may be a more robust coastal change method. ?? 2012 Blackwell Publishing Ltd.

Validating Bayesian truth serum in large-scale online human experiments.

Frank, Morgan R; Cebrian, Manuel; Pickard, Galen; Rahwan, Iyad

2017-01-01

Bayesian truth serum (BTS) is an exciting new method for improving honesty and information quality in multiple-choice survey, but, despite the method's mathematical reliance on large sample sizes, existing literature about BTS only focuses on small experiments. Combined with the prevalence of online survey platforms, such as Amazon's Mechanical Turk, which facilitate surveys with hundreds or thousands of participants, BTS must be effective in large-scale experiments for BTS to become a readily accepted tool in real-world applications. We demonstrate that BTS quantifiably improves honesty in large-scale online surveys where the "honest" distribution of answers is known in expectation on aggregate. Furthermore, we explore a marketing application where "honest" answers cannot be known, but find that BTS treatment impacts the resulting distributions of answers.

Full Text Available This study has the general aim to analyze whether the juridical decision is committed to the truth – or it is satisfied with something else, given the impossibility of grasping it in its entirety and perfection. From the hypothetical-deductive method of approach and techniques of indirect documentary research, especially literature, among national and foreign authors of the study of rhetoric, we seek to meet the specific objectives of assessing the relevance of “truth” in production of juridical decision, connect this analysis to the resurgence of Rhetoric experienced in the twentieth century, and evaluate whether such a decision may waive the dogmatic attachment to an ontological, unisonous and unquestionable truth. It concludes in the end that the search for truth as correspondence or link to reality does not always deserve prestige in models of institutionalized conflict resolution throughout the history of Western civilization. The juridical decision appears much more committed to the rhetoric gnosiology, ordering the speeches according to a language that enables the basis on which such a decision is built and therefore the persuasion of those involved, as without the discursive intersubjectivity, different observers may not report to other what they perceive - thus the legal analysis of the truth cannot ignore the dialectic of Rhetoric.

Strategies for cloud-top phase determination: differentiation between thin cirrus clouds and snow in manual (ground truth) analyses

Hutchison, Keith D.; Etherton, Brian J.; Topping, Phillip C.

1996-12-01

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.

Fear as 'Disclosure of Truths': The Educational Significance of An Existential-Phenomenological Insight

Directory of Open Access Journals (Sweden)

Jani Kukkola

2014-06-01

Full Text Available The article illustrates a particular existential-phenomenological view of the emotion of fear and its connection to self-educative process of grasping the world and gaining self-knowledge. According to this view, originally promoted by Martin Heidegger (1889-1976 and in educational philosophy Otto Friedrich Bollnow (1907-1991, fear is closely connected to a specific understanding of 'unconcealment', or 'disclosure' of truths. In the article it is shown, that this understanding sheds special educational insights on the connection between fear and gaining knowledge.

How Many Subjects are Needed for a Visual Field Normative Database? A Comparison of Ground Truth and Bootstrapped Statistics.

Phu, Jack; Bui, Bang V; Kalloniatis, Michael; Khuu, Sieu K

2018-03-01

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.

Telling the truth in a crisis

Shea, Jamie

2002-01-01

Full text: My presentation will focus on communicating in a crisis. Drawing on my experience as NATO's Spokesman during the Kosovo air campaign and, more recently, the fight against terrorism in Afghanistan, I will outline the pressures that the media place on organizations once they are in the media spotlight. I will discuss the importance of real time information, how to deal with mistakes and how to organize a media campaign in order to seize the initiative and put one's message across. What kind of organization do you need and how do you ensure that all the players are properly coordinated? What are the target audiences and how do you deal effectively with opponents seeking to discredit your handling of the crisis? My presentation will look at the respective merits of using TV, radio, newspapers and Internet as means of crisis communication. It will also highlight the increasing role of NGOs in setting the media agenda. In an environment dominated by PR executives and 'spin doctors', the challenge is to combine truth and credibility with organization and professionalism while staying calm under pressure. How NATO attempted to meet this challenge in Kosovo, learning from the inevitable mistakes it made along the way, will be a lesson that applies to any organization caught - voluntarily or involuntarily - in a sudden crisis.

Truth or beauty science and the quest for order

CERN Document Server

Orrell, David

2012-01-01

In this sweeping book, applied mathematician and popular author David Orrell questions the promises and pitfalls of associating beauty with truth, showing how ideas of mathematical elegance have inspired—and have sometimes misled—scientists attempting to understand nature. Orrell shows how the ancient Greeks constructed a concept of the world based on musical harmony; later thinkers replaced this model with a program, based on Newton’s “rational mechanics,” to reduce the universe to a few simple equations. He then turns to current physical theories, such as supersymmetric string theory—again influenced by deep aesthetic principles. The book sheds new light on historical investigations and also recent research, including the examinations ongoing at the Large Hadron Collider. Finally, broadening his discussion to other fields of research, including economics, architecture, and health, Orrell questions whether these aesthetic principles reflect an accurate way to explain and understand the structure...

The need for sustainable management of fresh water resources is one of the great challenges of the 21st century. Since most of the planet's liquid fresh water exists as groundwater, it is essential to develop non-invasive geophysical techniques to characterize groundwater aquifers. A field experiment was conducted in the High Plains Aquifer, central United States, to explore the mechanisms governing the non-invasive Surface NMR (SNMR) technology. We acquired both SNMR data and logging NMR data at a field site, along with lithology information from drill cuttings. This allowed us to directly compare the NMR relaxation parameter measured during logging,T2, to the relaxation parameter T2* measured using the SNMR method. The latter can be affected by inhomogeneity in the magnetic field, thus obscuring the link between the NMR relaxation parameter and the hydraulic conductivity of the geologic material. When the logging T2data were transformed to pseudo-T2* data, by accounting for inhomogeneity in the magnetic field and instrument dead time, we found good agreement with T2* obtained from the SNMR measurement. These results, combined with the additional information about lithology at the site, allowed us to delineate the physical mechanisms governing the SNMR measurement. Such understanding is a critical step in developing SNMR as a reliable geophysical method for the assessment of groundwater resources.

Predictors of technical adoption and behavioural change to transport energy-saving measures in response to climate change

International Nuclear Information System (INIS)

Aini, M.S.; Chan, S.C.; Syuhaily, O.

2013-01-01

Energy conservation can be achieved through the adoption of technical measures or the changing of one's behaviour. A survey of 201 Malaysian public personnel was conducted to examine the predictors of these two types of transport energy-saving measures in response to climate change. The results indicated that there were significant differences in the relative acceptability of both behavioural measures with respect to gender, level of education, income, knowledge of climate change and attitude. Gender, knowledge of causes of climate change and personal norm were predictors for the acceptability of technical measures, while perceived efficacy and personal norm were the factors that influenced the acceptability of behavioural measures. The results also indicated that distinctions ought to be made between technology adoption and behaviour modifications that require lifestyle changes when assessing pro-environmental intent behaviour. The implications for theory and practice are discussed. - Highlights: • A survey was conducted to examine acceptability of transport energy-saving measures. • Gender, knowledge of causes, efficacy and personal norm are predictors of technical measures. • Personal norm and perceived efficacy influenced acceptability of behavioural change. • Both measures are strongly correlated to psychological factors than to socio-demographic variables

For the latter third of the twentieth century, researchers have estimated production and cost functions for physician practices. Today, those attempting to measure the inputs and outputs of physician practice must account for many recent changes in models of care delivery. In this paper, we review practice inputs and outputs as typically described in research on the economics of medical practice, and consider the implications of the changing organization of medical practice and nature of physician work. This evolving environment has created conceptual challenges in what are the appropriate measures of output from physician work, as well as what inputs should be measured. Likewise, the increasing complexity of physician practice organizations has introduced challenges to finding the appropriate data sources for measuring these constructs. Both these conceptual and data challenges pose measurement issues that must be overcome to study the economics of modern medical practice. Despite these challenges, there are several promising initiatives involving data sharing at the organizational level that could provide a starting point for developing the needed new data sources and metrics for physician inputs and outputs. However, additional efforts will be required to establish data collection approaches and measurements applicable to smaller and single specialty practices. Overcoming these measurement and data challenges will be key to supporting policy-relevant research on the changing economics of medical practice.

Can you catch a liar? How negative emotions affect brain responses when lying or telling the truth.

Directory of Open Access Journals (Sweden)

Alice Mado Proverbio

Full Text Available The capacity to deceive others is a complex mental skill that requires the ability to suppress truthful information. The polygraph is widely used in countries such as the USA to detect deception. However, little is known about the effects of emotional processes (such as the fear of being found guilty despite being innocent on the physiological responses that are used to detect lies. The aim of this study was to investigate the time course and neural correlates of untruthful behavior by analyzing electrocortical indexes in response to visually presented neutral and affective questions. Affective questions included sexual, shameful or disgusting topics. A total of 296 questions that were inherently true or false were presented to 25 subjects while ERPs were recorded from 128 scalp sites. Subjects were asked to lie on half of the questions and to answer truthfully on the remaining half. Behavioral and ERP responses indicated an increased need for executive control functions, namely working memory, inhibition and task switching processes, during deceptive responses. Deceptive responses also elicited a more negative N400 over the prefrontal areas and a smaller late positivity (LP 550-750 ms over the prefrontal and frontal areas. However, a reduction in LP amplitude was also elicited by truthful affective responses. The failure to observe a difference in LP responses across conditions likely results from emotional interference. A swLORETA inverse solution was computed on the N400 amplitude (300-400 ms for the dishonest - honest contrast. These results showed the activation of the superior, medial, middle and inferior frontal gyri (BA9, 11, 47 and the anterior cingulate cortex during deceptive responses. Our results conclude that the N400 amplitude is a reliable neural marker of deception.

Continuous observations of temporal variations in the Earth's gravity field have recently become available at an unprecedented resolution of a few hundreds of kilometers. The gravity field is a product of the Earth's mass distribution, and these data—provided by the satellites of the Gravity Recovery And Climate Experiment (GRACE)—can be used to study the exchange of mass both within the Earth and at its surface. Since the launch of the mission in 2002, GRACE data has evolved from being an experimental measurement needing validation from ground truth, to a respected tool for Earth scientists representing a fixed bound on the total change and is now an important tool to help unravel the complex dynamics of the Earth system and climate change. In this review, we present the mission concept and its theoretical background, discuss the data and give an overview of the major advances GRACE has provided in Earth science, with a focus on hydrology, solid Earth sciences, glaciology and oceanography.

In a clinical setting, theories of health behaviour change could help audiologists and other hearing health care professionals understand the barriers that prevent people with hearing problems to seek audiological help. The transtheoretical (stages of change) model of health behaviour change is one of these theories. It describes a person's journey towards health behaviour change (e.g. seeking help or taking up rehabilitation) in separate stages: precontemplation, contemplation, preparation, action, and, finally, maintenance. A short self-assessment measure of stages of change may guide the clinician and facilitate first appointments. This article describes correlations between three stages of change measures of different lengths, one 24-item and two one-item. Participants were recruited through an online hearing screening study. Adults who failed the speech-in-noise recognition screening test and who had never undergone a hearing aid fitting were invited to complete further questionnaires online, including the three stages of change measures. In total, 224 adults completed the three measures. A majority of the participants were categorised as being in one of the information- and help-seeking stage of change (contemplation or preparation). The three stages of change measures were significantly correlated. Conclusions Our results support further investigating the use of a one-item measure to determine stages of change in people with hearing impairment.

Ilakkuvan, Vinu; Turner, Monique Mitchell; Cantrell, Jennifer; Hair, Elizabeth; Vallone, Donna

Turner's Anger Activism Model (AAM) contends anger and efficacy interact in a unique way to determine message responses to campaign materials. This study tested the AAM using responses to 2 truth antismoking advertisements collected in August-October 2014 via an online, cross-sectional survey of 15- to 21-year-olds. Those aware of each of the truth advertisements (n = 319 for each) were organized into 4 anger/efficacy groups. Analysis of variance and regressions were conducted to understand group differences in message-related cognitions (persuasiveness, receptivity, conversation). Message cognitions were highest among the high anger/high efficacy group and lowest among the low anger/low efficacy group.

Some Notes (with Badiou and Žižek on Event/Truth/Subject/Militant Community in Jean-Paul Sartre's Political Thought

Directory of Open Access Journals (Sweden)

Erik M. Vogt

2015-12-01

Full Text Available The main object of this paper is to examine the new philosophical frame proposed by Alain Badiou and Slavoj Žižek and to show that it implies some traces of Sartre's philosophical and political heritage. According the project of Alain Badiou and Slavoj Žižek one should no longer accept today's constellation of freedom, particularistic truth and democracy, but to (reinscribe the issues of freedom and universal truth into a political project that attempts to re-activate a thinking of revolution. Their thinking consists in the wager that it is still possible to provide a philosophical frame for this leftist emancipatory position that claims the dimension of the universal against the vicious circle of capitalist globalization-cum-particularization and, by following Marx's claim that there are formal affinities between the ambitions of emancipatory politics and the working mode of capitalism, takes up the struggle of universalism against globalization (capital. It is only through this struggle for the universal that the intertwined processes of a constant expansion of the automatism of capital and "a process of fragmentation into closed identities," accompanied by "the culturalist and relativist ideology" (Badiou can be suspended. It is precisely this constellation of revolutionary act, universal truth, subject, and militant community, that reveal some similarities with Sartre's concepts of the subject, the revolutionary action, the militant community a.o.

Estimation of uncertainty in tracer gas measurement of air change rates.

Science.gov (United States)

Iizuka, Atsushi; Okuizumi, Yumiko; Yanagisawa, Yukio

2010-12-01

Simple and economical measurement of air change rates can be achieved with a passive-type tracer gas doser and sampler. However, this is made more complex by the fact many buildings are not a single fully mixed zone. This means many measurements are required to obtain information on ventilation conditions. In this study, we evaluated the uncertainty of tracer gas measurement of air change rate in n completely mixed zones. A single measurement with one tracer gas could be used to simply estimate the air change rate when n = 2. Accurate air change rates could not be obtained for n ≥ 2 due to a lack of information. However, the proposed method can be used to estimate an air change rate with an accuracy of air change rate can be avoided. The proposed estimation method will be useful in practical ventilation measurements.

Lewis SE, Fowler NE. Changes in intervertebral disk dimensions after a loading task and the relationship with stature change measurements. To test the hypothesis that there would be a linear relationship between overall stature change determined by stadiometry and markers of lumbar disk height loss determined from magnetic resonance imaging (MRI). The short-term loading response of the lumbar spine was evaluated with both stadiometry and MRI, using a within-subject repeated-measures design. Measures were obtained both before and after 15 minutes of walking wearing a weighted vest (20% of body mass). Stature loss measured on the stadiometer was compared with change in lumbar spine length assessed from the MRI images. A university laboratory. Participants (N=13; mean age +/- SD, 28.5+/-5.2y; mean height +/- SD, 1.76+/-0.10m; mean body mass +/- SD, 76.6+/-14.9kg) were invited to take part in the investigation. The group was mixed (9 men, 4 women) and comprised people with no history of low back pain. Not applicable. Lumbar spine length assessed via MRI and stature change measured via stadiometry. A significant height loss was observed over the complete lumbar spine (Pstature loss (r=.61). The results were supportive of the use of stadiometry as an indirect measure of changes in intervertebral disk height.

A double-pass interferometer for measurement of dimensional changes

2008-01-01

A double-pass interferometer was developed for measuring dimensional changes of materials in a nanoscale absolute interferometric dilatometer. This interferometer realized the double-ended measurement of a sample using a single-detection double-pass interference system. The nearly balanced design, in which the measurement beam and the reference beam have equal optical path lengths except for the path difference caused by the sample itself, makes this interferometer have high stability, which is verified by the measurement of a quasi-zero-length sample. The preliminary experiments and uncertainty analysis show that this interferometer should be able to measure dimensional changes with characteristic uncertainty at the nanometer level

Fictionalized History: Signifying Changes to the Malaysian Nation and Identity

Directory of Open Access Journals (Sweden)

Sim Chee Cheang

2016-04-01

Full Text Available As one of the cornerstones of fiction, writers often use and confront history in their claim to “reality” and “identity” in their writing. Linda Hutcheon’s claim for “a postmodern concern for the multiplicity and dispersion of truth(s; truth(s relative to the specificity of place and culture” (1988, p. 108 is relevant to the use of history in recent Malaysian literature. The multiple and varied claims of truth(s as reflected through the fictionalizing of Malaysian history is the focus of the analysis in this article, which aims to expose the social, economic, and political implications of the Malaysian identity. The analysis of three current works of fictionalized Malaysian history from the different fictional genres of comic series, children’s history, and occidental history, represents a cross section of genres that challenge the supremacy of history’s ontological claim over identity. The deliberate contestation of received Malaysian history in fictional modes acknowledges the peripheral identity structures of race, religion, and economics that are sensitive in a multiracial country such as Malaysia.

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.

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. PMID:19949495

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.

Populism, Exclusion, Post-truth. Some Conceptual Caveats Comment on "The Rise of Post-truth Populism in Pluralist Liberal Democracies: Challenges for Health Policy".

Science.gov (United States)

De Cleen, Benjamin

2017-07-15

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. © 2018 The Author(s); Published by Kerman University of Medical Sciences.

Measurement of resistivity changes in irradiated microscopy discs

International Nuclear Information System (INIS)

Sagisaka, M.; Isobe, Y.; Edwards, D.J.; Garner, F.; Okita, T.

2007-01-01

Full text of publication follows: The successful operation of next generation fusion or fission devices will require the development of new inspection tools to allow in-situ, non-destructive examination of structural components which experience the deleterious effects of neutron irradiation. Such development requires that an understanding of how radiation-induced microstructural alteration contributes to macroscopic changes in physical properties such as electrical resistivity. This in turn requires test specimens spanning a range of microstructural alteration. Frequently such specimens are very small and available test techniques are not suitable for their examination. An example is the use of thin TEM specimens (3 mm diameter, 0.3 mm thick) used for electron microscopy. A unique four probe electrical resistivity measurement system suitable for examining I EM specimens was developed for investigating small resistivity changes due to void swelling and other microstructural features. Since this system uses momentarily-high electrical currents (0.5 A maximum), electrical resistivity changes can be measured rather precisely. This paper reports results of resistivity change measurements made on model Fe-Cr-Ni-Zr austenitic alloys irradiated in the Fast Flux Test Facility in the Materials Open Test Assembly to doses ranging from 0.38 to 19.2 dpa. Microscopy was used to determine the radiation-induced microstructure. A correlation is presented for resistivity changes arising primarily from void swelling. (authors)

The Secret Downing Street Memo and the Politics of Truth: A Performance Text

2006-10-01

Full Text Available Reading forward from the recently released secret Downing Street Memos, to the 2001 No Child Left Behind Act, in this performance text I critique the Bush Administration and its reliance on science, or evidence-based models of inquiry (SBR. SBR raises issues concerning the politics of truth and evidence. These issues intersect with the ways in which a given political regime fixes facts to fit ideology. Three versions of SBR are discussed, as is a model of science as disruptive cultural practice. I conclude by calling for a merger of critical pedagogy with a prophetic, feminist post-pragmatism.

Changes in Handset Performance Measures due to Spherical Radiation Pattern Measurement Uncertainty

DEFF Research Database (Denmark)

Nielsen, Jesper Ødum; Pedersen, Gert Frølund

An important characteristic of a mobile handset is its ability to receive and transmit power. One way to characterize the performance of a handset in this respect is to use measurements of the spherical radiation pattern from which the total radiated power (TRP), total isotropic sensitivity (TIS)...... with respect to the environment. Standard deviations up to about 0.5dB and a maximum deviation of about 1.6dB were found....... in the performance measures are investigated for both the GSM-900 and the GSM-1800 band. Despite the deliberately large deviations from the reference position, the changes in TRP and TIS are generally within ±0.5dB with a maximum of about 1.4dB. For the MEG values the results depend on the orientation of the handset...... system that may introduce errors in standardized performance measurements. Radiation patterns of six handsets have been measured while they were mounted at various offsets from the reference position defined by the Cellular Telecommunications & Internet Association (CTIA) certification. The change...

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

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

Truthfulness in transplantation: non-heart-beating organ donation

Directory of Open Access Journals (Sweden)

Potts Michael

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.

A measurement error model for physical activity level as measured by a questionnaire with application to the 1999-2006 NHANES questionnaire.

Systematic investigations into the structure of measurement error of physical activity questionnaires are lacking. We propose a measurement error model for a physical activity questionnaire that uses physical activity level (the ratio of total energy expenditure to basal energy expenditure) to relate questionnaire-based reports of physical activity level to true physical activity levels. The 1999-2006 National Health and Nutrition Examination Survey physical activity questionnaire was administered to 433 participants aged 40-69 years in the Observing Protein and Energy Nutrition (OPEN) Study (Maryland, 1999-2000). Valid estimates of participants' total energy expenditure were also available from doubly labeled water, and basal energy expenditure was estimated from an equation; the ratio of those measures estimated true physical activity level ("truth"). We present a measurement error model that accommodates the mixture of errors that arise from assuming a classical measurement error model for doubly labeled water and a Berkson error model for the equation used to estimate basal energy expenditure. The method was then applied to the OPEN Study. Correlations between the questionnaire-based physical activity level and truth were modest (r = 0.32-0.41); attenuation factors (0.43-0.73) indicate that the use of questionnaire-based physical activity level would lead to attenuated estimates of effect size. Results suggest that sample sizes for estimating relationships between physical activity level and disease should be inflated, and that regression calibration can be used to provide measurement error-adjusted estimates of relationships between physical activity and disease.

At high concentrations, certain fluorophores undergo self-quenching, i.e., fluorescence intensity decreases with increasing fluorophore concentration. Accordingly, the self-quenching properties can be used for measuring water volume changes in lipid vesicles. In cells, quantitative determination...... concentrations of the fluorophore calcein suitable for measurement of changes in cell water volume by self-quenching. The relationship between calcein fluorescence intensity, when excited at 490 nm (its excitation maximum), and calcein concentration was investigated in vitro and in various cultured cell types...... to a decrease in calcein fluorescence with high signal-to-noise ratio (>15). Similar results were obtained with the fluorophore BCECF when excited at its isosbestic wavelength (436 nm).

Paradigm shifts about dust on the Moon: From Apollo 11 to Chang'e-4

that Apollo dust is the major surface problem for risk management plans of lunar expeditions. As of 1 February 2018, a second paradigm change awaits transparent authoritative Ground truth measurements by Chang'e-4 or other relevant dust detectors to compare with Apollo 12 DDE measurements. Re-examination of risk management of effects of Apollo dust is essential for international expeditions including a Moon Village and Google Lunar XMedal competitors. Future DAPs could refine a third paradigm shift for Moon, moving from the past and present Earth-centric cultures of an inert Moon to cultures with visions of Moon as an active and close Extraterrestrial neighbour, because its outermost sunlit two cm of dusty plasmas are a variable soup of lunar and Extraterrestrial plasmas. An emphasis on its research seems a neat fit with the Directive of President Trump on 11 December 2017 to "Lead an innovative and sustainable program of exploration with commercial and international partners" to "lead the return of humans to the Moon for long-term exploration and utilization". It would also be measurement-based now thus less costly, more safe and quicker than any human visit to Mars.

Full Text Available A questão sobre a verdade, se não for bem colocada, pode dificultar o encontro e o diálogo entre teologia e literatura. A elaboração da ficção não é necessariamente distanciamento da verdade, nem o discurso teológico é o único verdadeiro. A metafísica tradicional já afirmava o belo e o verdadeiro como transcendentais. Hoje, mesmo em ciências, debate-se sobre a compreensão da verdade uma vez que tal conceito não é simples nem unívoco. Reconhecendo que há diversas ordens de verdade e diferentes caminhos para atingi-la, o texto enfoca as distintas maneiras de se colocar o problema da verdade em literatura e em teologia, mas de maneira a facilitar um real diálogo entre elas mostrando, por uma rápida referência aos estudos bíblicos, que tal diálogo é possível e mesmo desejável. Ali, não há que se opor, por exemplo, a verdade histórica à verdade literária, que é aquela apresentada pelo texto, mas busca-se alcançar a “verdade de salvação”, aquela que vai se relacionar de maneira mais direta com a fé.Palavras-Chave: Verdade.

Nowadays, even in science, there is a debate about the understanding of the truth since this concept is not simple, nor univocal. The text recognizes that there are several orders of truth and also different ways to achieve it. In other words, the paper looks at different ways of putting the question of truth in literature and in theology, aiming to facilitate the dialogue between them.Keywords: Truth.

Estimation of Uncertainty in Tracer Gas Measurement of Air Change Rates

2010-12-01

Full Text Available Simple and economical measurement of air change rates can be achieved with a passive-type tracer gas doser and sampler. However, this is made more complex by the fact many buildings are not a single fully mixed zone. This means many measurements are required to obtain information on ventilation conditions. In this study, we evaluated the uncertainty of tracer gas measurement of air change rate in n completely mixed zones. A single measurement with one tracer gas could be used to simply estimate the air change rate when n = 2. Accurate air change rates could not be obtained for n ≥ 2 due to a lack of information. However, the proposed method can be used to estimate an air change rate with an accuracy of

2015-09-01

In this paper, we give a comparative study on three Multilayer Markov Random Field (MRF) based solutions proposed for change detection in optical remote sensing images, called Multicue MRF, Conditional Mixed Markov model, and Fusion MRF. Our purposes are twofold. On one hand, we highlight the significance of the focused model family and we set them against various state-of-the-art approaches through a thematic analysis and quantitative tests. We discuss the advantages and drawbacks of class comparison vs. direct approaches, usage of training data, various targeted application fields and different ways of Ground Truth generation, meantime informing the Reader in which roles the Multilayer MRFs can be efficiently applied. On the other hand we also emphasize the differences between the three focused models at various levels, considering the model structures, feature extraction, layer interpretation, change concept definition, parameter tuning and performance. We provide qualitative and quantitative comparison results using principally a publicly available change detection database which contains aerial image pairs and Ground Truth change masks. We conclude that the discussed models are competitive against alternative state-of-the-art solutions, if one uses them as pre-processing filters in multitemporal optical image analysis. In addition, they cover together a large range of applications, considering the different usage options of the three approaches.

Direct Speaker Gaze Promotes Trust in Truth-Ambiguous Statements.

Kreysa, Helene; Kessler, Luise; Schweinberger, Stefan R

2016-01-01

A speaker's gaze behaviour can provide perceivers with a multitude of cues which are relevant for communication, thus constituting an important non-verbal interaction channel. The present study investigated whether direct eye gaze of a speaker affects the likelihood of listeners believing truth-ambiguous statements. Participants were presented with videos in which a speaker produced such statements with either direct or averted gaze. The statements were selected through a rating study to ensure that participants were unlikely to know a-priori whether they were true or not (e.g., "sniffer dogs cannot smell the difference between identical twins"). Participants indicated in a forced-choice task whether or not they believed each statement. We found that participants were more likely to believe statements by a speaker looking at them directly, compared to a speaker with averted gaze. Moreover, when participants disagreed with a statement, they were slower to do so when the statement was uttered with direct (compared to averted) gaze, suggesting that the process of rejecting a statement as untrue may be inhibited when that statement is accompanied by direct gaze.

Toward a limited realism for psychiatric nosology based on the coherence theory of truth.

Science.gov (United States)

Kendler, K S

2015-04-01

A fundamental debate in the philosophy of science is whether our central concepts are true or only useful instruments to help predict and manipulate the world. The first position is termed 'realism' and the second 'instrumentalism'. Strong support for the instrumentalist position comes from the 'pessimistic induction' (PI) argument. Given that many key scientific concepts once considered true (e.g., humors, ether, epicycles, phlogiston) are now considered false, how, the argument goes, can we assert that our current concepts are true? The PI argument applies strongly to psychiatric diagnoses. Given our long history of abandoned diagnoses, arguments that we have finally 'gotten it right' and developed definitive psychiatric categories that correspond to observer-independent reality are difficult to defend. For our current diagnostic categories, we should settle for a less ambitious vision of truth. For this, the coherence theory, which postulates that something is true when it fits well with the other things we confidently know about the world, can serve us well. Using the coherence theory, a diagnosis is real to the extent that it is well integrated into our accumulating scientific data base. Furthermore, the coherence theory establishes a framework for us to evaluate our diagnostic categories and can provide a set of criteria, closely related to our concept of validators, for deciding when they are getting better. Finally, we need be much less skeptical about the truth status of the aggregate concept of psychiatric illness than we are regarding the specific categories in our current nosology.

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.

Given that over 97 percent of American teens play videogames, it is not surprising that many "games for health" target youth. Although tobacco use is the leading cause of preventable death in the United States, few digital games focus on preventing this behavior. The aims of this study were twofold: (1) to determine if youth will play a game with tobacco-related information and themes and (2) to explain the relationship between the truth(®) (Legacy, Washington, DC) campaign's "Flavor Monsters" gameplay and shifts in game-related tobacco knowledge, attitudes, and beliefs. First, two versions of the game, with different amounts of tobacco-related content, were developed to examine the influence of tobacco-related content on player engagement, length of play, awareness of the truth brand, and receptivity to the game. No statistically significant differences were found for engagement (P=0.81), length of play (P=0.10), or awareness of the truth brand (P=0.67). Using an online survey through a preexisting online panel of 13-24 year olds, a longitudinal (n=693) design was used whereby exposure to messages varied naturally over time. Because of the large number of anti-tobacco industry attitude questions, we created an Anti-Tobacco Industry (ATI) Index based on the results of a factor analysis. Although gameplay was not a predictor of lower levels of intention to smoke, level mastered was a significant positive predictor of ATI Index attitudes score at 3 months, controlling for baseline ATI Index score, age, gender, and ever cigarette use (P=0.002). Longitudinal findings indicate a cumulative and enduring effect, suggesting that anti-tobacco content can be successfully integrated within a mobile game to help increase anti-tobacco attitudes.

The Odiousness of Greek Debt in Light of the Findings of the Greek Debt Truth Committee

Unlike the popular narrative, which suggests that the Greek debt crisis was the result of lavish spending, this article demonstrates that the ‘crisis’ was generated by a transformation of purely private debt into public debt. This finding is supported by the preliminary report of the Greek Parliamentary Committee on the Truth of the Greek Debt, which clearly demonstrated the exponential increase of private debt in Greece risked the collapse of the private financial institutions exposed to it,...

This study used structural equation modeling to test a theory-based model of the pathways by which exposure to the "truth" counterindustry media campaign influenced beliefs, attitudes, and smoking behavior in national random-digit-dial telephone surveys of 16,000 12- to 17-year-olds before, 8 months after, and 15 months after campaign launch. Consistent with concepts from the theory of reasoned action, youth in markets with higher levels of campaign exposure had more negative beliefs about tobacco industry practices and more negative attitudes toward the tobacco industry. Models also provided support for a social inoculation effect, because negative industry attitudes were associated with lower receptivity to protobacco advertising and with less progression along a continuum of smoking intentions and behavior.

Power, right, and truth: Foucault's triangle as a model for clinical power.

Science.gov (United States)

Polifroni, E Carol

2010-01-01

Power has historically been viewed from a position of dominance and authority. Using this lens leads one to a destiny wherein one individual or society has power over another. The power over approach is a hierarchical view, one that leads to someone else being oppressed, and one wherein the prevailing hegemony continues. If a different lens is used, wherein power does not reside within a position, but rather, within a person and within a relationship bounded by knowledge, a new destiny of power to and power of is created. These two approaches to power are examined and clinical power is offered as a lens that culminates in the understanding of power as a right and as truth imbedded with awareness and relationships.

This report documents the Government Applications Task Force (GATF) Buried Waste Project. The project was initiated as a field investigation and verification of the 1994 Strategic Environmental Research and Development Program's (SERDP) Buried Waste Identification Project results. The GATF project team included staff from three US Department of Energy (DOE) Laboratories [Oak Ridge National Laboratory (ORNL), Los Alamos National Laboratory (LANL), and the Savannah River Technology Center (SRTC)] and from the National Exploitation Laboratory. Similar studies were conducted at each of the three DOE laboratories to demonstrate the effective use of remote sensing technologies. The three locations were selected to assess differences in buried waste signatures under various environmental conditions (i.e., climate, terrain, precipitation, geology, etc.). After a brief background discussion of the SERDP Project, this report documents the field investigation (ground truth) results from the 1994--1995 GATF Buried Waste Study at ORNL's Waste Area Grouping (WAG) 4.

We offer and test a brief psychosocial intervention, Speaking Truth to EmPower (STEP), designed to protect underrepresented minorities' (URMs) intellectual performance and safety in science, technology, engineering, and math (STEM). STEP takes a 'knowledge as power' approach by: (a) providing a tutorial on stereotype threat (i.e., a social contextual phenomenon, implicated in underperformance and early exit) and (b) encouraging URMs to use lived experiences for generating be-prepared coping strategies. Participants were 670 STEM undergraduates [URMs (Black/African American and Latina/o) and non-URMs (White/European American and Asian/Asian American)]. STEP protected URMs' abstract reasoning and class grades (adjusted for grade point average [GPA]) as well as decreased URMs' worries about confirming ethnic/racial stereotypes. STEP's two-pronged approach-explicating the effects of structural 'isms' while harnessing URMs' existing assets-shows promise in increasing diversification and equity in STEM.

GRACE, time-varying gravity, Earth system dynamics and climate change

2014-01-01

Continuous observations of temporal variations in the Earth's gravity field have recently become available at an unprecedented resolution of a few hundreds of kilometers. The gravity field is a product of the Earth's mass distribution, and these data—provided by the satellites of the Gravity Recovery And Climate Experiment (GRACE)—can be used to study the exchange of mass both within the Earth and at its surface. Since the launch of the mission in 2002, GRACE data has evolved from being an experimental measurement needing validation from ground truth, to a respected tool for Earth scientists representing a fixed bound on the total change and is now an important tool to help unravel the complex dynamics of the Earth system and climate change. In this review, we present the mission concept and its theoretical background, discuss the data and give an overview of the major advances GRACE has provided in Earth science, with a focus on hydrology, solid Earth sciences, glaciology and oceanography.

The Tissue Removal Assessment with Ultrasound of the SFA and Popliteal (TRUTH) study assessed the performance of the orbital atherectomy system (OAS) to treat femoropopliteal arteries, including determining its effect on plaque removal. Patients with symptomatic femoropopliteal peripheral arterial disease were treated with the OAS followed by adjunctive balloon angioplasty (BA). Intravascular ultrasound (IVUS) images were collected pre- and post-OAS and post-OAS BA. Patients were followed through 12 months post-procedure. Twenty-nine lesions were treated with OAS-BA in 25 patients. The mean maximum balloon inflation pressure was 5.2 ± 1.2 atm. Virtual histology IVUS (VH-IVUS) analysis revealed at the maximum calcium ablation site that calcium reduction was responsible for 86% of the lumen area increase. The minimum lumen area increased from 4.0 mm(2) to 9.1 mm(2) (<.0001), and the percentage of area stenosis decreased from 76.9% to 43.0% (<.0001) after OAS-BA. At 12 months, the target lesion revascularization rate was 8.2%, and ankle-brachial index and Rutherford classification improved significantly from baseline through follow-up. The VH-IVUS analysis reveals that OAS modifies the calcified component of the plaque burden. It is hypothesized that calcium modification by OAS changes the lesion compliance, allowing for low pressure adjunctive BA. The clinical outcomes were favorable through 12-month follow-up. © The Author(s) 2015.

Vulnerability Assessment, Climate Change Impacts and Adaptation Measures in Slovenia

Science.gov (United States)

Cegnar, T.

2010-09-01

In relation to the priority tasks of the climate change measures, the Republic of Slovenia estimates that special attention needs to be devoted to the following sectors in general: - sectors that currently indicate a strong vulnerability for the current climate variability (for instance, agriculture), - sectors where the vulnerability for climate change is increased by current trends (for instance, urban development, use of space), - sectors where the adaptation time is the longest and the subsequent development changes are connected with the highest costs (for instance, use of space, infrastructural objects, forestry, urban development, building stock). Considering the views of Slovenia to the climate change problem in Europe and Slovenia, priority measures and emphasis on future adaptation to climate change, the Republic of Slovenia has especially exposed the following action areas: - sustainable and integrated management of water sources for water power production, prevention of floods, provision of water for the enrichment of low flow rates, and preservation of environmental function as well as provision of water for other needs; - sustainable management of forest ecosystems, adjusted to changes, for the provision of their environmental function as well as being a source of biomass, wood for products for the conservation of carbon, and carbon sinks; - spatial planning as one of the important preventive instruments for the adaptation to climate change through the processes of integral planning of spatial and urban development; - sustainable use and preservation of natural wealth and the preservation of biodiversity as well as ecosystem services with measures and policies that enable an enhanced resistance of ecosystems to climate change, and the role of biological diversity in integral adaptation measures; - informing and awareness on the consequences of climate change and adaptation possibilities. For years, the most endangered sectors have been agriculture and

Ground-truthing predicted indoor radon concentrations by using soil-gas radon measurements

International Nuclear Information System (INIS)

Reimer, G.M.

2001-01-01

Predicting indoor radon potential has gained in importance even as the national radon programs began to wane. A cooperative study to produce radon potential maps was conducted by the Environmental Protection Agency (EPA), U.S. Geological Survey (USGS), Department of Energy (DOE), and Lawrence Berkeley Laboratory (LBL) with the latter taking the lead role. A county-wide predictive model based dominantly on the National Uranium Resource Evaluation (NURE) aerorad data and secondly on geology, both small-scale data bases was developed. However, that model breaks down in counties of complex geology and does not provide a means to evaluate the potential of an individual home or building site. Soil-gas radon measurements on a large scale are currently shown to provide information for estimating radon potential at individual sites sort out the complex geology so that the small-scale prediction index can be validated. An example from Frederick County, Maryland indicates a positive correlation between indoor measurements and soil-gas data. The method does not rely on a single measurement, but a series that incorporate seasonal and meteorological considerations. (author)

Direct Speaker Gaze Promotes Trust in Truth-Ambiguous Statements.

Directory of Open Access Journals (Sweden)

Helene Kreysa

Full Text Available A speaker's gaze behaviour can provide perceivers with a multitude of cues which are relevant for communication, thus constituting an important non-verbal interaction channel. The present study investigated whether direct eye gaze of a speaker affects the likelihood of listeners believing truth-ambiguous statements. Participants were presented with videos in which a speaker produced such statements with either direct or averted gaze. The statements were selected through a rating study to ensure that participants were unlikely to know a-priori whether they were true or not (e.g., "sniffer dogs cannot smell the difference between identical twins". Participants indicated in a forced-choice task whether or not they believed each statement. We found that participants were more likely to believe statements by a speaker looking at them directly, compared to a speaker with averted gaze. Moreover, when participants disagreed with a statement, they were slower to do so when the statement was uttered with direct (compared to averted gaze, suggesting that the process of rejecting a statement as untrue may be inhibited when that statement is accompanied by direct gaze.

Performance measurement of workplace change: in two different cultural contexts

Directory of Open Access Journals (Sweden)

Chaiwat Riratanaphong

2014-01-01

Full Text Available Nowadays, organisations must cope with the pressure of cost reduction and efficiency in order to succeed in a highly competitive business environment. However, drivers to improve social interaction and employee’s performance and as such to contribute to organisational goals and objectives make it necessary to be concerned with other performance criteria as well, such as effectiveness, flexibility, employee satisfaction, productivity and creativity. There is a growing need for performance management and performance measurement that not only covers all aspects of an organisation, but which can be applied to various situations in a changing internal and external environment. Performance measurement methods which include an integrated perspective of performance have become essential. In addition, it has been realised that corporate real estate can contribute to organisational performance (Nourse and Roulac, 1993, De Vries et al., 2008, Lindholm, 2008, Den Heijer, 2011, Jensen et al., 2012. For this reason, worldwide organisations started to implement new ways of working in a more open and flexible work environment. Although there are various objectives and drivers of workplace change, the common objectives are to reduce costs and to increase efficiency. The changing organisational and external contexts, such as the increasing demand for talented knowledge workers and changing work patterns, have led to the development of new offices that can promote social networks and interaction among employees. The new workplace does not only aim at achieving cost efficiency, but it should also support employee satisfaction and productivity. This PhD research focuses on both themes i.e. performance measurement of workplace change. The aim of this research is to provide a conceptual framework that visualises the impact of workplace change on employees’ responses to the new work environment and to present guidelines on performance measurement of workplace

fMRI evidence for the role of recollection in suppressing misattribution errors: the illusory truth effect.

Science.gov (United States)

Mitchell, Jason P; Dodson, Chad S; Schacter, Daniel L

2005-05-01

Misattribution refers to the act of attributing a memory or idea to an incorrect source, such as successfully remembering a bit of information but linking it to an inappropriate person or time [Jacoby, L. L., Kelley, C., Brown, J., & Jasechko, J. (1989). Becoming famous overnight: Limits on the ability to avoid unconscious influences of the past. Journal of Personality and Social Psychology, 56, 326-338; Schacter, D. L. (1999). The seven sins of memory: Insights from psychology and cognitive neuroscience. American Psychologist, 54, 182-203; Schacter, D. L. (2001). The seven sins of memory: How the mind forgets and remembers. Boston: Houghton Mifflin]. Cognitive studies have suggested that misattribution errors may occur in the absence of recollection for the details of an initial encounter with a stimulus, but little is known about the neural basis of this memory phenomenon. Here we used functional magnetic resonance imaging (fMRI) to examine the hypothesized role of recollection in counteracting the illusory truth effect, a misattribution error whereby perceivers systematically overrate the truth of previously presented information. Imaging was conducted during the encoding and subsequent judgment of unfamiliar statements that were presented as true or false. Event-related fMRI analyses were conditionalized as a function of subsequent performance. Results demonstrated that encoding activation in regions previously associated with successful recollection--including the hippocampus and the ventrolateral prefrontal cortex (PFC)--correlated with the successful avoidance of misattribution errors, providing initial neuroimaging support for earlier cognitive accounts of misattribution.

2016-07-01

Psychometric properties and initial validity of the Brief Observation of Social Communication Change (BOSCC), a measure of treatment-response for social-communication behaviors, are described. The BOSCC coding scheme is applied to 177 video observations of 56 young children with ASD and minimal language abilities. The BOSCC has high to excellent inter-rater and test-retest reliability and shows convergent validity with measures of language and communication skills. The BOSCC Core total demonstrates statistically significant amounts of change over time compared to a no change alternative while the ADOS CSS over the same period of time did not. This work is a first step in the development of a novel outcome measure for social-communication behaviors with applications to clinical trials and longitudinal studies.

Deceptive Intentions: Can Cues to Deception Be Measured before a Lie Is Even Stated?

Directory of Open Access Journals (Sweden)

Sabine Ströfer

Full Text Available Can deceitful intentions be discriminated from truthful ones? Previous work consistently demonstrated that deceiving others is accompanied by nervousness/stress and cognitive load. Both are related to increased sympathetic nervous system (SNS activity. We hypothesized that SNS activity already rises during intentions to lie and, consequently, cues to deception can be detected before stating an actual lie. In two experiments, controlling for prospective memory, we monitored SNS activity during lying, truth telling, and truth telling with the aim of lying at a later instance. Electrodermal activity (EDA was used as an indicator of SNS. EDA was highest during lying, and compared to the truth condition, EDA was also raised during the intention to deceive. Moreover, the switch from truth telling toward lying in the intention condition evoked higher EDA than switching toward non-deception related tasks in the lie or truth condition. These results provide first empirical evidence that increased SNS activity related to deception can be monitored before a lie is stated. This implies that cues to deception are already present during the mere intention to lie.

Organizational readiness for implementing change: a psychometric assessment of a new measure.

Shea, Christopher M; Jacobs, Sara R; Esserman, Denise A; Bruce, Kerry; Weiner, Bryan J

2014-01-10

Organizational readiness for change in healthcare settings is an important factor in successful implementation of new policies, programs, and practices. However, research on the topic is hindered by the absence of a brief, reliable, and valid measure. Until such a measure is developed, we cannot advance scientific knowledge about readiness or provide evidence-based guidance to organizational leaders about how to increase readiness. This article presents results of a psychometric assessment of a new measure called Organizational Readiness for Implementing Change (ORIC), which we developed based on Weiner's theory of organizational readiness for change. We conducted four studies to assess the psychometric properties of ORIC. In study one, we assessed the content adequacy of the new measure using quantitative methods. In study two, we examined the measure's factor structure and reliability in a laboratory simulation. In study three, we assessed the reliability and validity of an organization-level measure of readiness based on aggregated individual-level data from study two. In study four, we conducted a small field study utilizing the same analytic methods as in study three. Content adequacy assessment indicated that the items developed to measure change commitment and change efficacy reflected the theoretical content of these two facets of organizational readiness and distinguished the facets from hypothesized determinants of readiness. Exploratory and confirmatory factor analysis in the lab and field studies revealed two correlated factors, as expected, with good model fit and high item loadings. Reliability analysis in the lab and field studies showed high inter-item consistency for the resulting individual-level scales for change commitment and change efficacy. Inter-rater reliability and inter-rater agreement statistics supported the aggregation of individual level readiness perceptions to the organizational level of analysis. This article provides evidence in

Looking for truth and finding lies: the prospects for a nascent neuroimaging of deception.

Science.gov (United States)

Spence, Sean A; Kaylor-Hughes, Catherine J

2008-01-01

Lying is ubiquitous and has acquired many names. In 'natural experiments', both pathological lying and truthfulness implicate prefrontal cortices. Recently, the advent of functional neuroimaging has allowed investigators to study deception in the non-pathological state. Prefrontal cortices are again implicated, although the regions identified vary across experiments. Forensic application of such technology (to the detection of deceit) requires the solution of tractable technical problems. Whether we 'should' detect deception remains an ethical problem: one for societies to resolve. However, such a procedure would only appear to be ethical when subjects volunteer to participate, as might occur during the investigation of alleged miscarriages of justice. We demonstrate how this might be approached.

Against Relativism. The Importance of Truth in the Ethics of St. John Paul II

Directory of Open Access Journals (Sweden)

Dorota Probucka

2016-04-01

Full Text Available The main aim of the paper is the analysis and critique of axiological relativism, typical of contemporary Western culture. Its supporters deny the objective status of moral norms and values. Axiological relativism leads to moral indifference based on blurring the difference between good and evil, and negating the belief that human action may be morally better or worse. I present the anti ‑relativistic position of St. John Paul II, particularly in relation to the truth, understood as a cognitive and moral value. According to the Pope, a civilization based on the belief of the relative nature of good and evil leads to widespread hypocrisy and is destined to a slow decline.

Role of cerebral blood volume changes in brain specific-gravity measurements

International Nuclear Information System (INIS)

Picozzi, P.; Todd, N.V.; Crockard, A.H.

1985-01-01

Cerebral blood volume (CBV) was calculated in gerbils from specific-gravity (SG) changes between normal and saline-perfused brains. Furthermore, changes in CBV were investigated during ischemia using carbon-14-labeled dextran (MW 70,000) as an intravascular marker. Both data were used to evaluate the possible error due to a change in CBV on the measurement of ischemic brain edema by the SG method. The methodological error found was 0.0004 for a 100% CBV change. This error is insignificant, being less than the standard deviation in the SG measured for the gerbil cortex. Thus, CBV changes are not responsible for the SG variations observed during the first phase of ischemia. These variations are better explained as an increase of brain water content during ischemia

Background Different approaches have been developed for measuring change. Direct measurement of change (transition ratings) requires asking a patient directly about his judgment about the change he has experienced (reported change). With indirect measures of change, the patients? status is assessed at different time points and differences between them are calculated (measured change). When using the quasi-indirect approach (?then-test?), patients are asked after an intervention to rate their ...

In this work we discuss the measurement protocols for indirect determination of the isothermal entropy change associated with first order phase transitions in caloric materials. The magneto-structural phase transitions giving rise to giant magnetocaloric effects in Cu-doped MnAs and FeRh are used as case studies to exemplify how badly designed protocols may affect isothermal measurements and lead to incorrect entropy change estimations. Isothermal measurement protocols which allow correct assessment of the entropy change around first order phase transitions in both direct and inverse cases are presented.

In a modern Earth science there is a great importance of understanding the processes, forming the benthic fluxes as one of element sources or sinks to or from the water body, which affects the elements balance in the water system. There are several ways to assess benthic fluxes and here we try to compare the results obtained by chamber experiments, calculated from porewater distributions and simulated with model. Benthic fluxes of dissolved elements (oxygen, nitrogen species, phosphate, silicate, alkalinity, iron and manganese species) were studied in the Baltic and Black Seas from 2000 to 2005. Fluxes were measured in situ using chamber incubations (Jch) and at the same time sediment cores were collected to assess the porewater distribution at different depths to calculate diffusive fluxes (Jpw). Model study was carried out with benthic-pelagic biogeochemical model BROM (O-N-P-Si-C-S-Mn-Fe redox model). It was applied to simulate biogeochemical structure of the water column and upper sediment and to assess the vertical fluxes (Jmd). By the behaviour at the water-sediment interface all studied elements can be divided into three groups: (1) elements which benthic fluxes are determined by the concentrations gradient only (Si, Mn), (2) elements which fluxes depend on redox conditions in the bottom water (Fe, PO4, NH4), and (3) elements which fluxes are strongly connected with organic matter fate (O2, Alk, NH4). For the first group it was found that measured fluxes are always higher than calculated diffusive fluxes (1.5disadvantages and the main facing us question is - which value should be taken for calculation the balance?

Investigation of metrological parameters of measuring system for small temperature changes

Full Text Available Metrological parameters of the non-standard contact device were investigated to characterize its performance in temperature change measurements in the specified temperature range. Several series thermistors with a negative temperature coefficient of resistance connected into a linearization circuit were used as the sensing element of the semiconductor device. Increasing the number of thermistors leads to improved circuitry resolving power and reduced dispersion of this parameter. However, there is the question of optimal ratio of the number of thermistors and implemented temperature resolution, due to the nonlinear resolution dependence of the number of series-connected thermoelements. An example of scheme of four similar thermistors as the primary sensor and of a standard measuring instrument, which is working in ohmmeter mode, shows the ability to measure temperature changes at the level of hundredth of a Celsius degree. In this case, a quantization error, which is determined by a resolution of the measuring system, and the ohmmeter accuracy make the main contribution to the overall accuracy of measuring small temperature changes.

Reply [to Comment on Earthquake precursors: Banished forever?] Comment: Unpredictability of earthquakes-Truth or fiction?

I agree with many of C. Lomnitz's points. I only wish to add that by the word “paradigm” I mean the entity as T. Kuhn defines it in The Nature of Scientific Revolutions, that is, a belief system considered as the truth by a scientific community for a certain amount of time. Kuhn's idea of scientific progress is by radical paradigm shifts. Earthquake prediction (EP) is a good example. It was a nonscience in 1960, and C. Richter warned every student in his Elementary Seismology that it is “a marsh light,” appealing to one from the darkness but leading those who respond to the swamp.

Mammographic density is a marker of breast cancer risk and diagnostics accuracy. Density change over time is a strong proxy for response to endocrine treatment and potentially a stronger predictor of breast cancer incidence. We developed STRATUS to analyse digital and analogue images and enable automated measurements of density changes over time. Raw and processed images from the same mammogram were randomly sampled from 41,353 healthy women. Measurements from raw images (using FDA approved software iCAD) were used as templates for STRATUS to measure density on processed images through machine learning. A similar two-step design was used to train density measures in analogue images. Relative risks of breast cancer were estimated in three unique datasets. An alignment protocol was developed using images from 11,409 women to reduce non-biological variability in density change. The protocol was evaluated in 55,073 women having two regular mammography screens. Differences and variances in densities were compared before and after image alignment. The average relative risk of breast cancer in the three datasets was 1.6 [95% confidence interval (CI) 1.3-1.8] per standard deviation of percent mammographic density. The discrimination was AUC 0.62 (CI 0.60-0.64). The type of image did not significantly influence the risk associations. Alignment decreased the non-biological variability in density change and re-estimated the yearly overall percent density decrease from 1.5 to 0.9%, p density measures was not influenced by mammogram type. The alignment protocol reduced the non-biological variability between images over time. STRATUS has the potential to become a useful tool for epidemiological studies and clinical follow-up.

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.

Radiotherapy may result in dryness of the skin even when no other change can be detected. We describe a system for recording the electrical conductance of skin as a measure of sweat gland function. In 22 normal volunteers close agreement was obtained between measurements obtained from comparable sites on both sides of the chest. Measurements were subsequently made in 38 patients treated by radiotherapy to one side of the chest for tumours of the breast or lung using one of five different fractionation schedules. Simultaneous readings were obtained from both sides of the chest with the non irradiated side acting as a control. A dose response relationship was demonstrated: five patients who received the equivalent total dose of 15 Gy in 2-Gy fractions showed no change in conductance. Sixteen out of 23 who received an equivalent total dose of 42-46 Gy in 2-Gy fractions had a greater than 22% reduction in mean skin conductance compared with that of the control areas despite the skin appearing normal in the large majority. Marked changes in skin conductance were seen after higher total doses. In a prospective study 18 women receiving breast irradiation underwent weekly readings during treatment. A mean reduction of 40% in skin conductance was noted by the end of the second week of treatment prior to any clinical evidence of radiation change. Skin conductance returned to normal in 44% of patients by 6 months. In the remainder, those patients who showed the greatest reduction in skin conductance during treatment demonstrated the least recovery. Changes in sweat gland function can be detected and quantified in skin which may otherwise appear normal. Differences may so be demonstrated between areas treated using different fractionation schedules and the method may be applied to the detection during radiotherapy of unusually sensitive patient.

Full Text Available The article analyses V.G. Rasputin’s journalism specifically marking that his journalism in 1990-s had an image of some non-personified force that consciously managed the processes (like the world government. Other articles by V.G. Rasputin form the view of literature as a way of national identity. He consistently appears as a righteous man and a preacher depending on the stage of aesthetic activities associated with cognition and production of ethical truth. In conclusion the author notes how the writer’s “pochvennichestvo” grew into the oppositional views of the society.
