This paper discusses the utilization of pilots' physiological indications such as electroencephalographic signals, ocular parameters, and pilot performance-based quantitative metrics to estimate cognitive workload. The study aims to derive a non-invasive technique to estimate pilot's cognitive workload and study their correlation with standard physiological parameters. Initially, we conducted a set of user trials using well-established psychometric tests for evaluating the effectiveness of pupil and gaze-based ocular metrics for estimating cognitive workload at different levels of task difficulty and lighting conditions. Later, (...) we conducted user trials with the NALSim flight simulator using a business class Learjet aircraft model. We analyzed participants' ocular parameters, power levels of different EEG frequency bands, and flight parameters for estimating variations in cognitive workload. Results indicate that introduction of secondary task increases pilot's cognitive workload significantly. The beta frequency band of EEG, nearest neighborhood index specifying distribution of gaze fixation, L1 Norm of power spectral density of pupil diameter, and the duty cycle metric indicated variations in cognitive workload.

Study on the life and Hindu philosophical works of Hãsarāja Svāmī, 1805-1856, Marathi writer.

In the case of magnetic resonance imaging (MRI) imaging, image processing is crucial. In the medical industry, MRI images are commonly used to analyze and diagnose tumor growth in the body. A number of successful brain tumor identification and classification procedures have been developed by various experts. Existing approaches face a number of obstacles, including detection time, accuracy, and tumor size. Early detection of brain tumors improves options for treatment and patient survival rates. Manually segmenting brain tumors from a significant (...) number of MRI data for brain tumor diagnosis is a tough and time-consuming task. Automatic image segmentation of brain tumors is required. The objective of this study is to evaluate the degree of accuracy and simplify the medical picture segmentation procedure used to identify the type of brain tumor from MRI results. Additionally, this work suggests a novel method for identifying brain malignancies utilizing the Bagging Ensemble with K-Nearest Neighbor (BKNN) in order to raise the KNN’s accuracy and quality rate. For image segmentation, a U-Net architecture is utilized first, followed by a bagging-based k-NN prediction algorithm for classification. The goal of employing U-Net is to improve the accuracy and uniformity of parameter distribution in the layers. Each decision tree is fitted on a little different training dataset during classification, and the bagged decision trees are effective since each tree has minor differences and generates slightly different skilled predictions. The overall classification accuracy was up to 97.7 percent, confirming the efficiency of the suggested strategy for distinguishing normal and pathological tissues from brain MR images; this is greater than the methods that are already in use.

Recently I have read in succession the four articles on formal logic and dialectics in the current year's Hsin chien-she: Mr. Chou Ku-ch'eng's "Formal Logic and Dialectics" in the second issue, Mr. I Chih's "A Criticism of Confused Concepts on Problems of Logic" in the fourth issue, Mr. Shen Ping-yuan's "A Discussion of ‘Formal Logic and Dialectics,’ " and Mr. Chou Ku-ch'eng's "Further Discourse on Formal Logic and Dialectics," both in the seventh issue. In my opinion, in Mr. Chou's articles, (...) several main theses on formal logic and on the relationship between formal logic and dialectics are erroneous; basically, I agree with the criticisms of Messrs. I and Shen. Nonetheless, I believe that Mr. Chou's errors have had their source in the theory of cognition in that he has unilateralized and absolutized certain aspects that were originally correct, thus leading himself in the wrong direction. In criticizing Mr. Chou, both Messrs. I and Shen failed to proceed from this premise, so they could not make others see where Mr. Chou's errors basically lie. Based on this approach, I am merely offering some personal views on several main problems concerning formal logic and the relationship between formal logic and dialectics as mentioned in Mr. Chou's article. It is hoped that Mr. Chou and other comrades will correct me. (shrink)

I.—It is a thesis of Christian philosophy that God can bring about anything that does not involve a contradiction in terms. Now a contradietion in terms is denned with reference to an identical proposition. An identical proposition is one in which the predicate is the same as the subject. This is brought about in two ways: one when the predicate is completely identical with the subject, as when you say, ‘A dog is a dog’: two when the predicate is partly (...) identical with the subject as when you say, ‘A black dog is black’, or ‘A dog is an animal’. In both these cases, especially in the latter, it is said that the predicate is included in the idea, or concept or ratio of the subject. If any of these propositions is denied, then you get a simultaneous affirmation and denial of the same thing, of dog, of black, and of animal, respectively, thus producing a contradiction in terms. And not even God can make such propositions true. (shrink)

It would seem that "possibility," "concrete actuality," and "decision" are terms indispensable in describing my existence. It may also be that the meaning of no one of these three terms may be adequately conceived without reference to the other two. By preferring to follow Santayana, Mr. Eddins emphasizes concrete actuality. Now, as I read Santayana, existence like essence is a category, not strictly a "realm" of being, a category that we come to respect as we act and make decisions. It (...) should not, even in Santayana's materialism, be considered in abstraction from critical situations. Santayana's animal faith accepts the presence of a concrete actuality, the "realm" of matter conceived as a field of action. I might add that a human faith will accept our act of decision that makes its terms with the changing conditions constituting this realm. Thus I have asserted that "to exist is to have an unfinished history and a problematic future, the two being united in decision." When I think of my own existence or that of my friends, I bear this meaning more or less clearly in mind. My own existence is apparent to me every time I consider my past and my open future as the margins of a decision that is being formulated in my mind. Suppose now that someone convinces me that my decisions do not face an open future but stand to their future in a strictly chronological relation comparable, let us say, to the relation of earlier and later events as portrayed in an elementary text-book of history. Then I must face the difficulties latent in Leibniz' theology. (shrink)

OBJECTIVE: How outside factors affect physician decision making remains an open question of vital importance. We sought to investigate the importance of various influences on physician decision making when clinical guidelines differ from patient preference. -/- METHODS: An online survey asking 469 primary care providers (PCPs) across four practice sites whether they would order magnetic resonance imaging for a patient with uncomplicated back pain. Participants were randomized to one of four scenarios: a patient's preference for imaging (control), a patient's preference (...) plus a colleague's opinion against imaging (colleague), a patient's preference plus a professional society's recommendation against imaging (profession), or a patient's preference plus an accountable care organization's quality metric that measures physician use of imaging (ACO). Demographic information and the reasoning behind participants' decisions also were obtained. -/- RESULTS: A total of 168 PCPs completed the survey, yielding a 36% completion rate. A majority chose not to pursue imaging: control 68%, colleague 85%, profession 87%, and ACO 78%. Multivariate logistic regression revealed that participants were more likely not to order advanced imaging only when reminded of a professional society recommendation (P = 0.017). Regression also suggested that practice site exerted an effect on the primary outcome. Evidence-based medicine and clinical judgment were the most cited reasons for the decision. -/- CONCLUSIONS: Our results reinforce the potential to leverage professional societies to advance evidence-based medicine and reduce unnecessary testing. At the same time, practice site appeared to exert influence, suggesting that these recommendations must be part of local institutional culture to be effective. (shrink)

The preceding symposium articles speculate on the psychosocial dynamics of discrimination as reverberating with grief, mourning, melancholia, and denial. They invite a psychoanalytic paradox on the fate of inchoate loss and its complex relation to oppression and depression: constellations of attachment to loss met with its social and psychical disavowal render inexpressible to the other the work of mourning and drive its myriad expressions. A different way of putting the dilemma is that grief calls upon symbolic equation and the pain (...) of symbolization. Deborah Britzman's coda reads the psychoanalyst Melanie Klein's consideration of depression as the origin of the human condition with Paulo Freire's call to educators for a radical humanization to release oppression. Between Freire's Pedagogy of the Oppressed and Klein's Love, Guilt, and Reparation, the coda traces a signifying loss that attests to the entwined roots of the self/other matrix with attention to the needed fluctuations within interiority and exteriority, loss and the depressive position, illness and health, and psychoanalysis with pedagogy.

Bovine tuberculosis is the most important animal health and welfare policy issue in Britain. Badgers are a wildlife reservoir of disease, although the eight-year Independent Scientific Group Randomised Badger Culling Trial concluded with a recommendation against culling. The report advised government that bovine TB could be controlled, and ultimately eradicated, by cattle-based measures alone. Despite the ISG recommendation against culling, the farming and veterinary industries continued to lobby government for a badger cull. The 2005–2010 Labour government followed the ISG advice (...) and decided against a cull. The 2010–2015 Coalition and the 2015-present Conservative governments have followed a badger culling policy. This paper investigates whether a virtuous government would cull badgers. It provides an overview of virtue theory in the context of government animal health and welfare policy. Bovine TB and badger control policy options are then analysed in the context of the virtues of justice, wisdom, integrity, loyalty, curiosity, trust, empathy, compassion and aesthetics. Justice is the first virtue of government, and badger culling is seriously problematic from a virtue perspective given that five badgers are culled per cow that avoids slaughter as a result. Analysis based on other virtues strongly suggests that government should not cull badgers. The paper concludes that a virtuous government would not cull badgers as part of policy to control bovine TB in cattle. (shrink)

Dedicated to Marilyn Monroe, the treatise opens with a poem in her memory by the author, a former boxer and world traveler. This book is for souls beyond religious orthodoxy who are ready for spiritual development along the road to the spiritual acropolis which the author has already reached. Mr. Durant holds that Karmic justice is satisfied through reincarnation, and that an incarnated liability is a sign of an unjust doing in a previous life. A principle of Karmic reaction is (...) involved. Thus, for example, an unloving wife will be an unloved wife in her next life. Our goal is to become "Christened or anointed." A somewhat perplexing theory of mind is also offered.—P. S. (shrink)

About twenty years ago this essay was unjustly ridiculed. The parallel which Mr. Siegel draws between beauty in art and self-integration may have seemed far-fetched, for it is indeed his thesis that "the resolution of conflict in self is like the making one of opposites in art." The integration of opposites into a coherent whole is central to his analysis of the structures of Self and World. The spirit of the aesthetics is basically Deweyian, and the essay might be viewed (...) as an incipient phenomenology of well-being.—P. S. (shrink)

Mrs. Fahs is an ordained Unitarian minister, who has over fifty years of experience in children's religious education.

An attempt to come to grips with the problem of how we acquire new concepts or how we develop new theories. Mr. Schon builds his theory on the basis of the idea that we do deal with new situations, or with old situations in new ways, and that we can do so only in terms of "old" theories—concepts which apply literally to other situations. He argues that we do so by "displacing" such concepts, using them as metaphors or projective models (...) for the new situation. This displacement both yields new concepts and conserves old assumptions uncritically. Mr. Schon devotes much attention to the role and nature of the metaphorical use of concepts, yet he fails to develop an explicit theory of their literal use.—K. P. F. (shrink)

These lines conclude the speech of Pompey to Cornelia when she met him on the shore of Lesbos after the disaster of Pharsalia. This speech Mr. Heitland in his excellent Introduction to Haskins' Lucan has stigmatised as ‘abominable’.1 So far as the bulk of the speech is concerned a plea may perhaps be urged in mitigation of this judgment. Cornelia has completely broken down at the sight of her unfortunate husband, and his first object should be to restore her to (...) herself. For this purpose, as all, not excluding Lucan, know, a tone of sharp chiding would be most effectual, and we learn from the sequel that it succeeded : ‘uocibus his correpta uiri uix aegra leuauit | membra solo’ . For the crude brutality of the statement in the last four words there is however no excuse. But happily it is not to be charged to Pompey or to Lucan, but to the editions. We should punctuate.

Mr Kerner believes that there has been a revolution in ethical theory during the present century and here discusses the views of some of the leading figures in the movement—Moore, Stevenson, Toulmin and Hare. Kerner is not very explicit on the precise nature of the revolution and, looking at the work of the members of this quartet, it is difficult to accept that any extraordinary change has occurred. Moore and Toulmin are Utilitarians, Stevenson a Subjectivist, Hare a Kantian. Each of (...) these has presented his views in a highly original and personal manner, but to have provided new bottles for old wine is hardly sufficient reason for being called revolutionaries. Moore has probably the best claim to originality—he could, with some justice, be said to have given a new thrust to moral philosophy and even to philosophy as a whole—but the defender of common sense would hardly recognize himself in the guise of a revolutionary. Perhaps it is time that those who speak of the revolution in philosophy and the revolution in ethics began to take seriously the quotation from Nestroy which Wittgenstein chose as the motto of his Philosophical Investigations: ‘It is in the nature of every advance that it appears much greater than it actually is’.

Introduction to, and overview of, the contents of the Symposium on consent and confidentialityThe papers in this symposium are based on a meeting held by the Academy of Medical Sciences in London on 12 February 2002. The decision to hold this meeting, and to explore in detail these important and contentious issues, arose from a number of concerns that the Academy felt about what may reasonably be called “impediments to medical research”.These include: The regulations arising from the implementation of the (...) European data protection directive and their effect on the gathering and holding of data needed for disease surveillance as well as for research. Phil Boyd, in his paper, presents the views and the work of the Information Commission, the responsible UK body in this area. The “Source Informatics” case where the Department of Health requested a judicial review on the use, by this company, of anonymised prescribing data from general practitioner records for informing the pharmaceutical industry about patterns of drug use. Mr Justice Latham ruled that the use of even this anonymised data for commercial purposes could be a breach of patients' rights to confidentiality. The Court of Appeal, however, emphatically reversed his decision and, no further appeal having been made to the House of Lords, the law of the land is now clear that there is no breach of confidentiality in the use of anonymised data. It did seem to us, …. (shrink)

At the outset of this chapter, I want to echo the praise offered by all of the contributors to this volume for Finder’s outstanding, thoughtful and self-critical narrative of the case of 83 year old Mrs. Hamadani and her fiercely devoted children. The brocade account is carefully woven, like a fine Persian tapestry, to convey the rich complexity of an actual ethics consultation as it transpires not over hours, but rather over days, weeks, months and even, as in this case, (...) years. Mrs. Hamadani’s narrative so told is replete with questions worthy of critical reflection. What is an appropriate role for ethics consultation in healthcare? How can an autonomy-centric culture accommodate community-centric cultural difference? How can or should the voice of the patient be heard when she cannot speak for herself and the much louder and anguished voices of others demand to be heard? What are the bounds of acceptable medical treatment and how should care teams respond when patient or family demands threaten to push care givers to cross those bounds? What is an appropriate response for ethics consultants when they are asked to take over a case or prevent a colleague from interacting with an unwilling family? Do the motivations of patients, family, or members of the care team in calling ethics consultants necessarily shape the consultant’s role? And so the list goes on, as the variety of commentaries which comprise the majority of this volume, as well as the multitude of discussions that you, the readers, will inevitably have with colleagues, students, and friends make abundantly clear.

This work is the product of several years of intense study of the various aspects of Kant's work, and the attempt to provide insights for students both with respect to the details of the Kantian system, and into the development and implications of the system as a whole. During that time many individuals have contributed to its ultimate formulation, and I would like to express my appreciation at least to the more generous contributors. For a careful reading of the manuscript (...) in its earlier forms, and suggestions which helped in many ways to improve the work and to crystalize its thesis, I would like to thank Professors Wilbur Long, A. C. Ewing, and Richard Bosley. For their interest and encouragement in the later stages of the project, I must thank Professor Lewis White Beck, and the many students who have taken my Kant seminar at the University of Alberta, especially Mr. Dieter Hartmetz. And finally, 1 acknowledge with pleasure my longstanding debt to Professor William H. Werkmeister for his years of critical advice and encouragement. Perhaps only Kant and my wife have contributed more to my philosophic development.
