After defining the concept of error as it applies to Roentgen semiotics, we present a typology of the sources of semiotic error in clinical practice. It is a typology based on clinical observation, with the Peircean Categories and the triadic structure of Roentgen signs as organizing principles. This is followed by a review of a general psychological typology of the sources of human error. We conclude with the demonstration of a Category preserving correspondence between psychologic and semiotic (...) sources of error. Thus, independently derived and empirically based typologies of psychologic and semiotic error are shown to have the same categorical structure. (shrink)

I examine error diagnosis (model-model disagreement) in climate model intercomparisons including its difficulties, fruitful examples, and prospects for streamlining error diagnosis. I suggest that features of climate model intercomparisons pose a more significant challenge for error diagnosis than do features of individual model construction and complexity. Such features of intercomparisons include, e.g., the number of models involved, how models from different institutions interrelate, and what scientists know about each model. By considering numerous examples in (...) the climate modeling literature, I distill general strategies (e.g., employing physical reasoning and using dimension reduction techniques) used to diagnose model error. Based on these examples, I argue that an error repertoire could be beneficial for improving error diagnosis in climate modeling, although constructing one faces several difficulties. Finally, I suggest that the practice of error diagnosis demonstrates that scientists have a tacit-yet-working understanding of their models which has been under-appreciated by some philosophers.

In lieu of an abstract, here is a brief excerpt of the content:Cognitive Error and Contemplative Practices:The Cultivation of Discernment in Mind and HeartWesley J. WildmanBrains are amazing organs in all creatures with central nervous systems and especially in human beings. But they are not perfect. Without forgetting the larger success story of cognitive evolution, I want to explore the way that cognitive biases sometimes produce errors in both religious and secular social settings and how such errors can be (...) diagnosed and corrected when they occur. This will involve noticing that error diagnosis and correction is a process that certain social groups have a vested interest in resisting or neglecting, in some respects, while the very same social groups may furnish resources that support the detection of cognitive errors, in other respects.This presents a moral quandary for both secular and religious groups. Should we educate children to be fully aware of their cognitive vulnerability to advertising, thereby learning how to resist and eventually become immune to one of the fundamental power sources of modern market economies? Should religious groups explain to young people their cognitive tendencies to posit the action of supernatural beings whether or not any such action exists, even though this may disrupt the power of religious groups to forge bracing social togetherness that supports psychologically useful coping skills? While I do not seek to answer such complex moral questions in this paper, I do argue that knowledge of cognitive biases and the resulting tendencies to cognitive error, self-defeating behaviors, and self-deception should be made available to those individuals and groups who are interested in promoting a high degree of critical self-awareness in the analysis of beliefs and behaviors in both secular and religious contexts.The term "error" is a potentially problematic one in that it misleadingly suggests that there might be a uniquely correct way in which cognition should work. I do not wish to suggest such a binary opposition. After all, biases exist in the human cognitive system either because they have been selected in the evolutionary process for their survival benefits or because they are side effects of other traits selected for their usefulness. My concern is with the wondrous human discovery that we can analyze [End Page 61] our behaviors and beliefs with such precision that we can sometimes detect when our cognitive biases produce mistaken beliefs and self-defeating behaviors. This forms the basis for my contention that cognition can often work better than it does—more accurately, less self-destructively—when tendencies to cognitive error are diagnosed, corrected, and perhaps even systematically resisted.The profound irony here is that the very same social groups (secular and religious) with an obvious vested interest in resisting such enlightenment in some respects can also promote processes of discernment and insight in other respects. Existing literature in the cognitive psychology of religion rarely bothers with such subtleties. It is common to assume that simply to notice the operation of cognitive biases in religion—say, in supporting belief in supernatural entities who providentially interact in human affairs, or in establishing and reinforcing people's willingness to defer to certain kinds of religious authority—is at the same time to establish the presence of rampant cognitive error, massive resistance to diagnosing and correcting it, and thus the infliction of pernicious cruelties on young children who have no way of escaping the resulting irrational indoctrination.This moral reflex to condemn religious groups because of their characteristic reluctance to acknowledge the role of cognitive biases in their beliefs and practices is understandable given the irrationality, ignorance, or denial that such reluctance suggests. I frankly acknowledge that I share this moral concern. But the actual complexities of religious practice demonstrate that the situation demands a subtler evaluation. Resistance to awareness of cognitive biases exists both inside and outside religious groups; economic and political practices in all eras and of all types have every bit as much to gain from neglecting to enlighten people about their cognitive operations as religious groups do—just consider the techniques employed in commercial advertising and political campaigns. Moreover, religious groups also promote methods of discernment and self-awareness that have historically been, and continue to be, the dominant method by which... (shrink)

All Galen's surviving shorter works on psychology and ethics - including the recently discovered Avoiding Distress, and the neglected Character Traits, extant only in Arabic - are here presented in one volume in a new English translation, with substantial introductions and notes and extensive glossaries. Original and penetrating analyses are provided of the psychological and philosophical thought, both of the above and of two absolutely central works of Galenic philosophy, Affections and Errors and The Capacities of the Soul, by some (...) of the foremost experts in the field. Each treatise has also been subjected to fresh textual study, taking account of the latest scholarly developments, and is presented with accompanying textual discussions, adding greatly to the value and accuracy of the work without detracting from its accessibility to a wider readership. The volume thus makes a major contribution to the understanding of the ancient world's most prominent doctor-philosopher in his intellectual context. (shrink)

The aim of this essay is to elaborate philosophical and ethical underpinnings of posthumous diagnosis of famous historical figures based on literary and artistic products, or commonly called retrospective diagnosis. It discusses ontological and epistemic challenges raised in the humanities and social sciences, and attempts to systematically reply to their criticisms from the viewpoint of clinical medicine, philosophy of medicine, particularly the ontology of disease and the epistemology of diagnosis, and medical ethics. The ontological challenge focuses on (...) the doubt about the persistence of a disease over historical time, whereas the epistemic challenge disputes the inaccessibility of scientific verification of a diagnosis in the past. I argue that the critics are in error in conflating the taxonomy of disease and the act of diagnosing a patient. Medical diagnosis is fundamentally a hypothesis-construction and an explanatory device that can be generated under various degrees of uncertainty and limited amount of information. It is not an apodictic judgment as the critics presuppose, but a probabilistic judgment with varying degrees of plausibility under uncertainty. In order to avoid this confusion, I propose that retrospective diagnosis of a historical figure be syndromic without identifying underlying disease, unless there is justifiable reason for such specification. Moreover it should be evaluated not only from the viewpoint of medical science but also in a larger context of the scholarship of the humanities and social sciences by its overall plausibility and consistency. On the other hand, I will endorse their concerns regarding the ethics and professionalism of retrospective diagnosis, and call for the need for situating such a diagnosis in an interdisciplinary scope and the context of the scholarship of the historical figure. I will then enumerate several important caveats for interdisciplinary retrospective diagnosis using an example of the retrospective diagnosis of Socrates for his life-long intermittent neurologic symptoms. Finally, I will situate the present argument in a larger context of the major debate among the historians of medicine and paleopathologists, and discuss the similarities and differences. (shrink)

Lennard Davis’s Biocultural Critique of the alleged certainty of diagnosis (Davis Journal of Bioethical Inquiry 7:227−235, 2010) makes errors of fact concerning psychiatric diagnostic categories, misunderstands the role of power in the therapeutic relationship, and provides an unsubstantiated and vague alternative to the management of psychological distress via a conceptually outdated model of the relationships between physical and psychological disease and illness. This response demonstrates that diagnostic knowledge vouchsafes legitimate power to physicians, and via them relief to patients who (...) suffer from psychological distress. The history of medicine and psychiatry demonstrates that psychiatric diagnosis shares many features with physical diagnosis, while there is also reason to believe that the two types will continue to be distinct in some respects. Diagnostic categories in psychological medicine, like those in physical medicine, are provisional, probabilistic, and often uncertain. These features do not detract from the dependence on diagnosis of therapeutic efficacy in both domains. (shrink)

This article begins with a criticism of Mclntyre and Gorovitz's account of medical error. Their theory implies that error, at least sometimes, it a necessary consequence of the inductive character of medical inquiry. The counter intuitive consequences of this account suggest that the issues surrounding induction may not be the most fertile area for developing a coherent interpretation of medical error. Given these shortcomings, I develop a new theory which assumes that the best philosophical soil for constructing (...) a theory of medical trror is the problem of universals. I then explain the problem and how the medical universal functions within arguments concerning diagnosis and treatment. A Wittgensteinian solution to the problem is presented which emphasizes the "borderline" character of some, if not many, medical judgments. Next, an argument is offered to establish that questions of medical error are not purely professional questions. This is because the theories used to make such professional judgments permit borderline cases even under the best circumstances. Finally, while there are a number of legitimate responses to this situation, I recommend one which involves legislative action. CiteULike Connotea Del.icio.us What's this? (shrink)

I here investigate whether there is any version of the principle of charity both strong enough to conflict with an error-theoretic version of nominalism (EN) about abstract objects, and supported by the considerations adduced in favour of interpretive charity in the literature. I argue that in order to be strong enough, the principle, which I call (Charity), would have to read, “For all expressions e, an acceptable interpretation must make true a sufficiently high ratio of accepted sentences containing e”. (...) I next consider arguments based on Davidson's intuitive cases for interpretive charity, the reliability of perceptual beliefs, and the reliability of “non-abstractive inference modes”, and conclude that none support (Charity). I then propose a diagnosis of the view that there must be some universal principle of charity ruling out (EN). Finally, I present a reason to think (Charity) is false, namely, that it seems to exclude the possibility of such disagreements as that between nominalists and realists. (shrink)

Medical diagnosis has been traditionally recognized as a privileged field of application for so called probabilistic induction. Consequently, the Bayesian theorem, which mathematically formalizes this form of inference, has been seen as the most adequate tool for quantifying the uncertainty surrounding the diagnosis by providing probabilities of different diagnostic hypotheses, given symptomatic or laboratory data. On the other side, it has also been remarked that differential diagnosis rather works by exclusion, e.g. by modus tollens, i.e. deductively. By (...) drawing on a case history, this paper aims at clarifying some points on the issue. Namely: 1) Medical diagnosis does not represent, strictly speaking, a form of induction, but a type, of what in Peircean terms should be called ‘abduction’ (identifying a case as the token of a specific type); 2) in performing the single diagnostic steps, however, different inferential methods are used for both inductive and deductive nature: modus tollens, hypothetical-deductive method, abduction; 3) Bayes’ theorem is a probabilized form of abduction which uses mathematics in order to justify the degree of confidence which can be entertained on a hypothesis given the available evidence; 4) although theoretically irreconcilable, in practice, both the hypothetical- deductive method and the Bayesian one, are used in the same diagnosis with no serious compromise for its correctness; 5) Medical diagnosis, especially differential diagnosis, also uses a kind of “probabilistic modus tollens”, in that, signs (symptoms or laboratory data) are taken as strong evidence for a given hypothesis not to be true: the focus is not on hypothesis confirmation, but instead on its refutation [Pr (¬ H/E1, E2, …, En)]. Especially at the beginning of a complicated case, odds are between the hypothesis that is potentially being excluded and a vague “other”. This procedure has the advantage of providing a clue of what evidence to look for and to eventually reduce the set of candidate hypotheses if conclusive negative evidence is found. 6) Bayes’ theorem in the hypothesis-confirmation form can more faithfully, although idealistically, represent the medical diagnosis when the diagnostic itinerary has come to a reduced set of plausible hypotheses after a process of progressive elimination of candidate hypotheses; 7) Bayes’ theorem is however indispensable in the case of litigation in order to assess doctor’s responsibility for medical error by taking into account the weight of the evidence at his disposal.

An investigation is presented in which a computer simulation model (DIAGNOSER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process‐tracing methodology in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). A second experiment performed with only DIAGNOSER identified conditions under which errors in reasoning in the first experiment could be related to interpretation of (...) specific data items. Predictions derived from DIAGNOSER's performance were tested in a third experiment with a new sample of subjects. Data from the three experiments indicated that (1) form of diagnostic reasoning was similar for all subjects trained in medicine and for the simulation model, (2) substance of diagnostic reasoning employed by the simulation model was parable with that of the more expert subjects, and (3) errors in subjects' reasoning were attributable to deficiencies in disease knowledge and the interpretation of specific patient data cues predicted by the simulation model.

Davidson’s error theory about metaphorical meaning has rightly commanded a lot of critical attention over the last twenty five or so years. Each component of that theory – the case for antirealism about metaphorical meanings, the diagnosis of the mistakes that led theorists to falsely ascribe such semantic properties to words and sentences, the suggested functional replacement of such talk in terms of the effects that metaphorical utterances bring about – has been examined, reformulated and criticised. The evaluation (...) of the theory has been far from uniformly negative. It is widely recognized, even by realists about metaphorical meaning, that the ‘conventional wisdom’ about ‘discerning two senses of the predicate term’ that Beardsley had adverted to three years earlier, was shown to be misguided by the considerations that Davidson’s paper brought to bear.[1] Contemporary recognition of the importance of elucidating the dependence of metaphorical language upon its literal base, and upon its context of utterance, can also be seen to have resulted from sustained critical engagement with Davidson’s article.

Radionics was the word used to describe the diagnosis of disease states.

The doctrine of idols is one of the most famous aspects of Bacon's thought. Yet his claim that the idols lead to madness has gone almost entirely unnoticed. This paper argues that Bacon's theory of idols underlies his diagnosis of the contemporary condition as one of ‘universal madness’. In contrast to interpretations that locate his doctrine of error and recovery within the biblical narrative of the Fall, the present analysis focuses on the material and cultural sources of the (...) mind's tendency towards error. It explains the idols in terms of Bacon's materialist psychology and his exposé of the debilitating effects of language and traditional learning. In so doing, it highlights the truly radical nature of the idols. For Bacon, the first step towards sanity was to alert people to the prevailing madness. The doctrine of idols was intended as a wake-up call, preparing the way for a remedy in the form of his new method of inquiry. The paper concludes by indicating how Bacon's method aimed to treat ‘universal madness’, and it suggests that his diagnosis influenced John Locke. (shrink)

Moritz Schlick’s work shaped Logical Empiricism and thereby an important part of philosophy in the first half of the 20th century. A continuous thread that runs through his work is a philosophical diagnosis of the ‘great errors in philosophy’: philosophers assume that there is intuitive knowledge/knowledge by acquaintance. Yet acquaintance, it is not knowledge, but an evaluative attitude. In this paper I will reconstruct Schlick’s arguments for this conclusion in the light of his early practical philosophy and his reading (...) of Schopenhauer’s The World as Will and Idea. Having the historical roots of Schlick’s position in view will put us in a position to explore and question its presuppositions. (shrink)

In coal mining industry, the running state of mine ventilators plays an extremely significant role for the safe and reliable operation of various industrial productions. To guarantee the better reliability, safety, and economy of mine ventilators, in view of early detection and effective fault diagnosis of mechanical faults which could prevent unscheduled downtime and minimize maintenance fees, it is imperative to construct some viable mathematical models for mine ventilator fault diagnosis. In this article, we plan to establish a (...) data-based mine ventilator fault diagnosis method to handle situations where engineers are absent or they are incapable of coming to a conclusion from multisource data. In the process of building the mine ventilator fault diagnosis model, considering that probabilistic rough sets could reduce the errors triggered by incompleteness, inconsistency, and inaccuracy without needing any additional assumptions and Pythagorean fuzzy multigranulation rough sets over the two universes’ model could effectively handle data representation, fusion, and analysis issues, we generalize the existing PF MGRSs over the two universes’ model to the PRS setting, as well as to further establish a novel model named Pythagorean fuzzy multigranulation probabilistic rough sets over two universes. In the granular computing paradigm, three types of PF MG-PRSs over two universes based on the risk attitude of engineers are proposed at first. Afterwards, several basic propositions of the newly proposed model are explored. Moreover, a PF multigranulation probabilistic model for mine ventilator fault diagnosis based on PF MG-PRSs over two universes is investigated. At last, a real-world case study of dealing with a mine ventilator fault diagnosis problem is given to illustrate the practicality of the presented model, and a validity test, a sensitivity analysis, and a comparison analysis are further explored to demonstrate the effectiveness of the presented model.

Position papers on artificial intelligence (AI) ethics are often framed as attempts to work out technical and regulatory strategies for attaining what is commonly called trustworthy AI. In such papers, the technical and regulatory strategies are frequently analyzed in detail, but the concept of trustworthy AI is not. As a result, it remains unclear. This paper lays out a variety of possible interpretations of the concept and concludes that none of them is appropriate. The central problem is that, by framing (...) the ethics of AI in terms of trustworthiness, we reinforce unjustified anthropocentric assumptions that stand in the way of clear analysis. Furthermore, even if we insist on a purely epistemic interpretation of the concept, according to which trustworthiness just means measurable reliability, it turns out that the analysis will, nevertheless, suffer from a subtle form of anthropocentrism. The paper goes on to develop the concept of strange error, which serves both to sharpen the initial diagnosis of the inadequacy of trustworthy AI and to articulate the novel epistemological situation created by the use of AI. The paper concludes with a discussion of how strange error puts pressure on standard practices of assessing moral culpability, particularly in the context of medicine. (shrink)

A superheterodyne receiver is a type of device universally used in a variety of electronics and information systems. Fault detection and diagnosis for superheterodyne receivers are therefore of critical importance, especially in noise environments. A general purpose fault detection and diagnosis scheme based on observers and residual error analysis was proposed in this study. In the scheme, two generalized regression neural networks are utilized for fault detection, with one as an observer and the other as an adaptive (...) threshold generator; faults are detected by comparing the residual error and the threshold. Then, time and frequency domain features are extracted from the residual error for diagnosis. A probabilistic neural network acts as a classifier to realize the fault diagnosis. Finally, to mimic electromagnetic environments with noise interference, simulation model under different fault conditions with noise interferences is established to test the effectiveness and robustness of the proposed fault detection and diagnosis scheme. Results of the simulation experiments proved that the presented method is effective and robust in simulated electromagnetic environments. (shrink)

This article is a contribution to interdisciplinary scholarship addressing the presumption of innocence, especially interdisciplinary conversations between philosophers and jurists. Terminological confusion and methodological traps and errors notoriously beset academic literature addressing the presumption of innocence and related concepts, such as evidentiary presumptions, and the burden and standard of proof in criminal trials. This article is diagnostic, in the sense that its primary objective is to highlight the assumptions—in particular, the disciplinary assumptions—implicit in influential contributions to debates on the presumption (...) of innocence. It advocates a methodologically pluralistic approach, according to which definitions of the presumption of innocence are necessarily sensitive to purpose and method. These relationships and their implications are not always appreciated, and are seldom explicitly elucidated. Notably, philosophers routinely treat the presumption of innocence as epistemic, evidentiary or otherwise featuring directly in practical reasoning. This article identifies jurisprudential and practical reasons why legal scholars and practitioners concerned with criminal procedure and evidence should reject evidentiary interpretations of the presumption of innocence. By encouraging finer-grained engagement with the history and institutional details of common law procedural traditions, the article aims to show why legal scholars might think that philosophical approaches to the presumption of innocence are already methodologically-loaded and, for our purposes, address the wrong questions with deficient concepts.

Computer vision is widely used in manufacturing, sports, medical diagnosis, and other fields. In this article, a multifeature fusion error action expression method based on silhouette and optical flow information is proposed to overcome the shortcomings in the effectiveness of a single error action expression method based on the fusion of features for human body error action recognition. We analyse and discuss the human error action recognition method based on the idea of template matching to (...) analyse the key issues that affect the overall expression of the error action sequences, and then, we propose a motion energy model based on the direct motion energy decomposition of the video clips of human error actions in the 3 Deron action sequence space through the filter group. The method can avoid preprocessing operations such as target localization and segmentation; then, we use MET features and combine with SVM to test the human body error database and compare the experimental results obtained by using different feature reduction and classification methods, and the results show that the method has the obvious comparative advantage in the recognition rate and is suitable for other dynamic scenes.

SummarySubjecting to a detailed analysis Kant's diagnosis of dialectical error in the Transcendental Dialectic of the first Critique, the author posits that Kant's understanding of such error is, to the extent that it conflates the subjective‐objective, phenomenal‐noumenal, and regulative‐constitutive distinctions, fundamentally incoherent. The author argues not only that these three distinctions cannot on Kant's own terms be conflated, but also that Kant's treatment of dialectical error is further vitiated by circularity of argument: Kant proposes to explain (...) the three distinctions by means of the notion of transcendental error, which however the distinctions themselves were supposed to explain in the first place. After showing that Kant's diagnosis of dialectical error cannot be salvaged even by resorting to the Kantian concept of “transcendental subreption”, the author concludes that unless Kant could in some other way spell out the minimal conditions for dialectical error, Kant's very distinction between understanding and reason becomes difficult to justify.

Determining appropriate legal responses to the conduct of health care workers who endanger patients continues to provoke fierce debate. This is particularly true in the context of criminal law, which offers punishment as an obvious strategy. In the first of three papers which make up this issue's extended Health Care Law feature, Professor Alexander McCall Smith and Dr Alan Merry argue against the prosecution of health care workers except in circumstances where there is very dear evidence of a culpable frame (...) of mind. They do so against the backdrop of their description of proposed changes in New Zealand legislation on medical manslaughter. The catalyst for this change was a judge's refusal to countenance the prosecution of an anaesthetist for manslaughter for inadvertent error. In the authors' opinion the intervention by the New Zealand judge has given rise to a long overdue review of a harsh penal measure. However, in a commentary on McCall Smith and Merry's paper, Ron Paterson argues that all is not what it seems and that--in the light of New Zealand's 'no fault' system of compensation for medical accident--the present system should be maintained.

The paper focuses on a difficult problem when formalizing knowledge: What about the possible concepts that didn’t make it into the formalization? We call such concepts the unconsidered context of the formalized knowledge and argue that erroneous and inadequate behavior of systems based on formalized knowledge can be attributed to different states of the unconsidered context; either while formalizing or during application of the formalization. We then propose an automatic strategy to identify different states of unconsidered context inside a given (...) formalization and to classify which parts of the formalization to use in a given application situation. The goal of this work is to uncover unconsidered context by observing sucess and failure of a given system in use. The paper closes with the evaluation of the proposed procedures in an error diagnosis scenario featuring a plan based user interface. (shrink)

Brian Garrett has criticized my diagnosis of the paradox of self-consciousness. In reply, I focus on the classification of 'I'-thoughts, and show how the notion of immunity to error through misidentification can be used to characterize 'I'-thoughts, even though an important class of 'I'-thoughts (those whose expression involves what Wittgenstein called the use of 'I' as object) are not themselves immune to error through misidentification. 'I'-thoughts which are susceptible to error through misidentification are dependent upon those (...) which are not. The dependence here has to do with how a thinker understands what would defeat such thoughts. (shrink)

In this paper we explain our pretense account of truth-talk and apply it in a diagnosis and treatment of the Liar Paradox. We begin by assuming that some form of deflationism is the correct approach to the topic of truth. We then briefly motivate the idea that all T-deflationists should endorse a fictionalist view of truth-talk, and, after distinguishing pretense-involving fictionalism (PIF) from error- theoretic fictionalism (ETF), explain the merits of the former over the latter. After presenting the (...) basic framework of our PIF account of truth-talk, we demonstrate a few advantages it offers over T-deflationist accounts that do not explicitly acknowledge pretense at work in the discourse. In turning to the Liar Paradox, we explain how the quasi-anaphoric functioning that our account attributes to truth-talk provides a diagnosis of the Liar Paradox (and other instances of semantic pathology) as having no content—in the sense of not specifying any of what we call M-conditions. At the same time, however, we vindicate the intuition that we can understand liar sentences, thereby avoiding one standard objection to “meaningless strategy” responses to the Liar Paradox. With this diagnosis in place, we then, by way of treatment, introduce a new predicate, ‘semantically defective’, and show how the explanation we give for its application allows for a consistent, yet revenge-immune, (dis)solution of the Liar Paradox, and semantic pathology generally.

A traditional diagnosis of the error in the Cartesian skeptical arguments holds that they exploit our tendencies to take a representationalist view of perception. Thinking (perhaps not too clearly) that we perceive only our own sensory states, it seems to us that our perceptual beliefs about physical objects must be justified qua explanations of those sensory states. Such justification requires us to have reasons to reject rival explanations, such as the skeptical hypotheses, which we lack.

Abstract: Background: In spite of the fact that computers continue to improve in speed and functions operation, they remain complex to use. Problems frequently happen, and it is hard to resolve or find solutions for them. This paper outlines the significance and feasibility of building a desktop PC problems diagnosis system. The system gathers problem symptoms from users’ desktops, rather than the user describes his/her problems to primary search engines. It automatically searches global databases of problem symptoms and solutions, (...) and also allows ordinary users to contribute exact problem reports in a structured manner. Objectives: The main goal of this Knowledge Based System is to get the suitable problem desktop PC symptoms and the correct way to solve the errors. Methods: In this paper the design of the proposed Knowledge Based System which was produced to help users of desktop PC in knowing many of the problems and error such as : Power supply problems, CPU errors, RAM dumping error, hard disk errors and bad sectors and suddenly restarting PC. The proposed Knowledge Based System presents an overview about desktop PC hardware errors are given, the cause of fault are outlined and the solution to the problems whenever possible is given out. CLIPS Knowledge Based System language was used for designing and implementing the proposed expert system. Results: The proposed PC desktop troubleshooting Knowledge Based System was evaluated by IT students and they were satisfied with its performance. (shrink)

Background:The concept of patient advocacy is still poorly understood and not clearly conceptualized. Therefore, there is a gap between the ideal of patient advocacy and the reality of practice. In order to increase nursing actions as a patient advocate, a comprehensive and clear definition of this concept is necessary.Research objective:This study aimed to offer a comprehensive and clear definition of patient advocacy.Research design:A total of 46 articles and 2 books published between 1850 and 2016 and related to the concept of (...) patient advocacy were selected from six databases and considered for concept analysis based on Rodgers’ evolutionary approach.Ethical considerations:This study was approved by the Research Ethics Committee of Tarbiat Modares University.Findings:The attributes of patient advocacy are safeguarding (track medical errors, and protecting patients from incompetency or misconduct of co-workers and other members of healthcare team), apprising (providing information about the patient’s diagnosis, treatment, and prognosis, suggesting alternatives of healthcare, and providing information about discharge program), valuing (maintaining self-control, enabling patients to make decisions freely, maintaining individualization and humanity, maintaining patient privacy, and acting in the patients’ values, culture, beliefs, and preferences), mediating (liaison between patients, families, and healthcare professionals, being patients’ voice, and communicate patient preferences and cultural values to members of the healthcare team), and championing social justice in the provision of healthcare (confronting inappropriate policies or rules in the healthcare system, identifying and correcting inequalities in delivery of health services, and facilitating access to community health services and health resources).Discussion and conclusion:The analysis of this concept can help to develop educational or managerial theories, design instruments for evaluating the performance of nurses in patient advocacy, develop strategies for enhancing patient advocacy, and improve the safety and quality of nursing care in the community and healthcare system.

Street’s “Darwinian Dilemma” is a well-known epistemological objection to moral realism. In this paper, I argue that “third-factor” replies to this argument on behalf of the moral realist, as popularized by Enoch :413–438, 2010, Taking morality seriously: a defense of robust realism, Oxford University Press, Oxford, 2011), Skarsaune :229–243, 2011) and Wielenberg :441–464, 2010, Robust ethics: the metaphysics and epistemology of godless normative realism, Oxford University Press, Oxford, 2014), cannot succeed. This is because they are instances of the illegitimate form (...) of reasoning known as “bootstrapping.” The phenomenon of bootstrapping has been discussed in detail, most notably by Vogel :602–623, 2000) and Cohen :309–329, 2002), in a different context as an objection to reliabilism and related theories of knowledge. I introduce four different characterizations of the error of bootstrapping from the epistemic literature in order to argue that the form of reasoning exemplified by third-factor replies would be deemed illegitimate by every one of them. I conclude that the moral realist should abandon third-factor replies, or else suggest a novel diagnosis for what goes wrong in bootstrapping cases that does not apply equally to the realist’s form of argument. However, I am not optimistic about the prospects for this latter strategy. (shrink)

The empirical diagnosis presented in this paper is based on interviews with nurse practitioners and physicians designed to elicit their perceptions of the nature and role of ethical dilemmas in clinical practice. Having selected five of these perceptions or views which were common and significant. the philosophical therapy offered consists in, first, a general discussion of ethical dilemmas, and second, a critical analysis of each of the five views with the aim of pointing out confusions and errors, the recognition (...) of which can be of applied and practical help in the clinical setting.

In this volume, leading philosophers of psychiatry examine psychiatric classification systems, including the Diagnostic and Statistical Manual of Mental Disorders, asking whether current systems are sufficient for effective diagnosis, treatment, and research. Doing so, they take up the question of whether mental disorders are natural kinds, grounded in something in the outside world. Psychiatric categories based on natural kinds should group phenomena in such a way that they are subject to the same type of causal explanations and respond similarly (...) to the same type of causal interventions. When these categories do not evince such groupings, there is reason to revise existing classifications. The contributors all question current psychiatric classifications systems and the assumptions on which they are based. They differ, however, as to why and to what extent the categories are inadequate and how to address the problem. Topics discussed include taxometric methods for identifying natural kinds, the error and bias inherent in DSM categories, and the complexities involved in classifying such specific mental disorders as "oppositional defiance disorder" and pathological gambling. -/- Contributors George Graham, Nick Haslam, Allan Horwitz, Harold Kincaid, Dominic Murphy, Jeffrey Poland, Nancy Nyquist Potter, Don Ross, Dan Stein, Jacqueline Sullivan, Serife Tekin, Peter Zachar.

A question, long discussed by legal scholars, has recently provoked a considerable amount of philosophical attention: ‘Is it ever appropriate to base a legal verdict on statistical evidence alone?’ Many philosophers who have considered this question reject legal reliance on bare statistics, even when the odds of error are extremely low. This paper develops a puzzle for the dominant theories concerning why we should eschew bare statistics. Namely, there seem to be compelling scenarios in which there are multiple sources (...) of incriminating statistical evidence. As we conjoin together different types of statistical evidence, it becomes increasingly incredible to suppose that a positive verdict would be impermissible. I suggest that none of the dominant views in the literature can easily accommodate such cases, and close by offering a diagnosis of my own. (shrink)

This innovative text is psychologically informed, both in its diagnosis of inferential errors, and in teaching students how to watch out for and work around their natural intellectual blind spots. It also incorporates insights from epistemology and philosophy of science that are indispensable for learning how to evaluate premises. The result is a hands-on primer for real world critical thinking. The authors bring a fresh approach to the traditional challenges of a critical thinking course: effectively explaining the nature of (...) validity, assessing deductive arguments, reconstructing, identifying and diagramming arguments, and causal and probabilistic inference. Additionally, they discuss in detail, important, frequently neglected topics, including testimony, including the evaluation of news and other information sources, the nature and credibility of science, rhetoric, and dialectical argumentation. The treatment of probability uses frequency trees and a frequency approach more generally, and argument reconstruction is taught using argument maps; these methods have been shown to improve students’ reasoning and argument evaluation.

The replication (replicability, reproducibility) crisis in social psychology and clinical medicine arises from the fact that many apparently well-confirmed experimental results are subsequently overturned by studies that aim to replicate the original study. The culprit is widely held to be poor science: questionable research practices, failure to publish negative results, bad incentives, and even fraud. In this article I argue that the high rate of failed replications is consistent with high-quality science. We would expect this outcome if the field of (...) science in question produces a high proportion of false hypotheses prior to testing. If most of the hypotheses under test are false, then there will be many false hypotheses that are apparently supported by the outcomes of well conducted experiments and null hypothesis significance tests with a type-I error rate (α) of 5%. Failure to recognize this is to commit the fallacy of ignoring the base rate. I argue that this is a plausible diagnosis of the replication crisis and examine what lessons we thereby learn for the future conduct of science. (shrink)

A review of the literature indicates that linear models are frequently used in situations in which decisions are made on the basis of multiple codable inputs. These models are sometimes used normatively to aid the decision maker, as a contrast with the decision maker in the clinical vs statistical controversy, to represent the decision maker "paramorphically" and to "bootstrap" the decision maker by replacing him with his representation. Examination of the contexts in which linear models have been successfully employed indicates (...) that the contexts have the following structural characteristics in common: each input variable has a conditionally monotone relationship with the output; there is error of measurement; and deviations from optimal weighting do not make much practical difference. These characteristics ensure the success of linear models, which are so appropriate in such contexts that random linear models may perform quite well. 4 examples involving the prediction of such codable output variables as GPA and psychiatric diagnosis are analyzed in detail. In all 4 examples, random linear models yield predictions that are superior to those of human judges. (shrink)

Confabulation is a symptom central to many psychiatric diagnoses and can be severely debilitating to those who exhibit the symptom. Theorists, scientists, and clinicians have an understandable interest in the nature of confabulation—pursuing ways to define, identify, treat, and perhaps even prevent this memory disorder. Appeals to confabulation as a clinical symptom rely on an account of memory’s function from which cases like the above can be contrasted. Accounting for confabulation is thus an important desideratum for any candidate theory of (...) memory. Many contemporary memory theorists now endorse Constructivism, where memory is understood as a capacity for constructing plausible representations of past events. Constructivism’s aim is to account for and normalize the prevalence of memory errors in everyday life. Errors are plausible constructions that, on a particular occasion have led to error. They are not, however, evidence of malfunction in the memory system. While Constructivism offers an uplifting repackaging of the memory errors to which we are all susceptible, it has troubling implications for appeals to confabulation in psychiatric diagnosis. By accommodating memory errors within our understanding of memory’s function, Constructivism runs the risk of being unable to explain how confabulation errors are evidence of malfunction. After reviewing the literature on confabulation and Constructivism, respectively, I identify the tension between them and explore how different versions of Constructivism may respond. The paper concludes with a proposal for distinguishing between kinds of false memory—specifically, between misremembering and confabulation—that may provide a route to their reconciliation. (shrink)

I am, of course, aware that infanticide was accepted and practiced in ancient Greece and Rome, and is still practiced in places like India and China today; just as I am aware that slavery was accepted and practiced in ancient Greece and Rome , and is still practiced in some places today. But if philosophers, no matter how sophisticated, were to step forward today to argue that slavery is morally acceptable , I would call that madness.Of course, the ‘madness’ I (...) am referring to in condemning the advocacy of infanticide and slavery or their moral permissibility is moral madness. I am not making a clinical diagnosis of a psychiatric condition. I take it that this was obvious, but that Charles Camosy is nevertheless troubled that I would say such a thing. But I do say it. And at the risk of giving offense, I will say it again: advocating the moral permissibility of killing healthy newborn infants is moral madness; and it is scandalous, especially in a journal expressly directed not merely to philosophers but to physicians, nurses and other healthcare professionals—people whose attitudes shape decisions they make about the lives of real people, including real infants.Whatever errors of fact and judgment are made possible by the complexities of human development or a prenatal ….

Quasi-realism aspires to preserve the intelligibility of the realist-sounding moral judgments of ordinary people. These judgments include ones of the form, “I believe that p, but I might be mistaken,” where “p” is some moral content. The orthodox quasi-realist strategy is to understand these in terms of the agent’s worrying that some improving change would lead one to aban-don the relevant moral belief. However, it is unclear whether this strate-gy generalizes to cases in which the agent takes their error (...) to be funda-mental in a sense articulated by Andy Egan. In an influential paper, Egan argues that it does not. Egan suggests that Blackburn’s approach is the only game in town for the quasi-realist when it comes to making sense of judgment of fallibility, and therefore concludes that Blackburn’s ina-bility to handle worries about fundamental moral error refutes quasi-realism tout court. Egan’s challenge has generated considerable discus-sion. However, in my view, we have not yet gotten to the heart of the matter. I argue that what is still needed is a fully general, quasi-realist-friendly theory of the nature of first-person judgments of fallibility, such that these judgments are demonstrably consistent with judging that the belief is stable in Egan’s sense. In this article, I develop and defend a fully general quasi-realist theory of such judgments, which meets this demand. With this theory in hand, I argue that Egan’s challenge can be met. Moreover, my discussion of how the challenge is best met provides an elegant diagnosis of where Egan’s argument against goes wrong. On my account, Egan’s argument equivocates at a key point between a “could” and a “would.”. (shrink)

Most of Terence Penelhum’s essays collected in his Themes in Hume are already recognized as classics in Hume scholarship. Bringing them together only reinforces their strengths: clarity and sensitivity in exposition combined with charity and acuity in criticism. Penelhum wrote them over a course of almost fifty years, and we can see in them the evolution in his attitude towards Hume. In the earliest essay — the 1955 ‘Hume on Personal Identity’ — Penelhum offers a quick and local diagnosis (...) of Hume’s errors: he has mistakenly assumed that an object must be unchanging for it to be identical through time. But in the later essays, especially the three new ones, Penelhum recognizes that his earlier local insights must be balanced by a wider reading of Hume. After all, he does not, for example, talk about the self only to say that it is a bundle of perceptions; it is also crucial to his treatment of the passions, especially the indirect, person-oriented passions, and is an essential component in his explanation of sympathy, the ultimate source of our moral judgments. Moreover, as Penelhum notes, seeing the self as constituted out of its perceptions, rather than standing over them so as to judge their legitimacy as guides to action or knowledge, is what allows Hume to attempt a ‘science of man’ — a quasi-Newtonian project of discovering the principles governing the perceptions in the mind-bundle.

In “Knowledge Under Threat” (Philosophy and Phenomenological Research 2012), Tomas Bogardus proposes a counterexample to the safety condition for knowledge. Bogardus argues that the case demonstrates that unsafe knowledge is possible. I argue that the case just corroborates the well-known requirement that modal conditions like safety must be relativized to methods of belief formation. I explore several ways of relativizing safety to belief-forming methods and I argue that none is adequate: if methods were individuated in those ways, safety would fail (...) to explain several much-discussed cases. I then propose a plausible externalist principle of method individuation. On the one hand, relativizing safety to belief-forming methods in the way suggested allows the defender of safety to account for the cases. On the other hand, it shows that the target known belief of Bogardus’s example is safe. Finally, I offer a diagnosis of a common error about the kind of cases that are typically considered potential counterexamples to the necessity of the epistemic condition: proponents of the alleged counterexamples mistake a strong condition that I call super-safety for safety.

The statistical technique of analysis of variance is often used by biologists as a measure of causal factors’ relative strength or importance. I argue that it is a tool ill suited to this purpose, on several grounds. I suggest a superior alternative, and outline some implications. I finish with a diagnosis of the source of error – an unwitting inheritance of bad philosophy that now requires the remedy of better philosophy.

The oddities in lottery cases and Moore’s paradox appear to support the knowledge account of assertion, according to which one should assert only what one knows. This paper preserves an emphasis on epistemic norms but presents grounds for an alternative explanation. The alternative divides the explanandum, explaining the error in lottery and Moorean assertions with one move and their deeper incoherence with another. The error derives from a respect in which the assertions are uninformative: the speaker is not (...) being appropriately responsive to her addressee’s epistemic needs. And the incoherence derives from a deeper respect in which lottery and some (but not all) Moorean assertions are uninformative: it is difficult to see how the speaker’s assertion could express any judgment she has made or would relevantly make, since she transparently lacks epistemic authority to inform any conceivable interlocutor on the subject. This diagnosis suggests an epistemic approach not directly to assertion but to judgment. Without judging that p, how could a speaker be in the business of informing her addressee that p? If the speaker transparently lacks authority to inform anyone whether p – to give anyone her word that p – how could she without confusion count as judging that p? (shrink)
