A class of problems is called decidable if there is an algorithm which will give the answer to any problem of the class after a finite length of time. The purpose of this paper is to discuss the classes of problems that can be solved by infinitely long decision procedures in the following sense: An algorithm is given which, for any problem of the class, generates an infinitely long sequence of guesses. The problem will be said to be solved in (...) the limit if, after some finite point in the sequence, all the guesses are correct and the same. Functions, sets, and functionals which are decidable by such infinite algorithms will be calledlimiting recursive. These, together with classes of objects which can beidentified in the limit, are the subjects of this report.Without qualification,setwill mean set of numbers;functionwill mean number-theoretic function of 1 variable, possibly partial;functionalswill take numerical values and have any number of numerical and/or function variables, the latter ranging solely over total functions of 1 variable. Thus a function is a special case of a functional,xwill invariably stand for a numerical variable;φfor a function variable;gfor a guess ;nfor the numerical variable which indexes the guesses, referred to as thetime.

About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could (...) further improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

Functional human brain mapping is commonly performed during invasive monitoring with intracranial electroencephalographic electrodes prior to resective surgery for drug­ resistant epilepsy. The current gold standard, electrocortical stimulation mapping, is time ­consuming, sometimes elicits pain, and often induces after discharges or seizures. Moreover, there is a risk of overestimating eloquent areas due to propagation of the effects of stimulation to a broader network of language cortex. Passive iEEG spatial-temporal functional mapping has recently emerged as a potential alternative to ESM. (...) However, investigators have observed less correspondence between STFM and ESM maps of language than between their maps of motor function. We hypothesized that incongruities between ESM and STFM of language function may arise due to propagation of the effects of ESM to cortical areas having strong effective connectivity with the site of stimulation. We evaluated five patients who underwent invasive monitoring for seizure localization, whose language areas were identified using ESM. All patients performed a battery of language tasks during passive iEEG recordings. To estimate the effective connectivity of stimulation sites with a broader network of task-activated cortical sites, we measured cortico-cortical evoked potentials elicited across all recording sites by single-pulse electrical stimulation at sites where ESM was performed at other times. With the combination of high gamma power as well as CCEPs results, we trained a logistic regression model to predict ESM results at individual electrode pairs. The average accuracy of the classifier using both STFM and CCEPs results combined was 87.7%, significantly higher than the one using STFM alone, indicating that the correspondence between STFM and ESM results is greater when effective connectivity between ESM stimulation sites and task-activated sites is taken into consideration. These findings, though based on a small number of subjects to date, provide preliminary support for the hypothesis that incongruities between ESM and STFM may arise in part from propagation of stimulation effects to a broader network of cortical language sites activated by language tasks, and suggest that more studies, with larger numbers of patients, are needed to understand the utility of both mapping techniques in clinical practice.

In the "cratylus", Plato presents two theories about the correctness of names, I.E., Names are correct by nature and names are correct by convention. In this paper, I argue that plato holds both views because he recognizes that the word 'name' is ambiguous as between type and token. Name tokens (individual strings of marks and noises) are conventional for plato. But name types (the role played by the tokens or the concept expressed by the tokens) are not conventional for plato.

This book explores numerous ways in which vulgar language, grotesque appearances, and horrific experiences affect us in our relationships with others and with ourselves. Its compelling case studies and revealing interviews bring together ideas and issues that are a lingering, but unexplored, focus in psychotherapy literature. The grotesque and the vulgar are major inhabitants of the vast unconscious. Their variations and haunting presence are anticipated and reflected in the transactions of everyday life. So too do they manifest themselves in our (...) social institutions, maintaining their presence in the seven lively arts as much as in mental hospitals, rehabilitation facilities, and psychotherapy practices. Most of all, the grotesque and vulgar challenge the contemporary search for meaning and sanity. This book will help the psychotherapist better deal with the rich soil of grotesqueness and vulgarity in the interplay between the psychotherapy patient and the experiential world. Reading it will open new vistas of treatment possibilities. As each contributing author explores the potentialities and obstacles inherent in the competing and complementing forces of the grotesque and socially condoned sensibilities, you will learn about the value of the grotesque in the consultation room. You will further learn how the flaunted and unconscious vulgarities of everyday life enrich the creative vision inherent in therapeutic conversations. Most important, you will be challenged by what it means to abide with the sometimes pesky vulgar and grotesque guises in each of your client's lives. Here's a sample of what you'll find in Inhabitants of the Unconscious: The Grotesque and the Vulgar in Everyday Life: Louis Fierman's recollection of his treatment of a Nazi soldier, which offers fascinating therapeutic possibilities when issues of the grotesqueare at hand an extraordinary analysis of the role of the grotesque in artwork, with special attention paid to the work of Hieronymus Bosch a fascinating look at Sigmund Freud's perspective on the grotesque&#; and what it says about Freud himself the remarkable formative experiences of children with craniofacial difference &#;an exposition that will enrich your therapeutic interventions with children and adolescents who face atypical challenges extraordinary case studies&#;by Robert Marchesani about his therapeutic endeavors with a Vietnam veteran caught in the aftermath of his incestuous past and by E.

J. Krishnamurti (1895-1986) was thought by many to be a modern-day equivalent of the Buddha. In fact, he was once even considered to be the second coming of Christ. While many think it wonderful to live and work in close proximity with such a person, it's difficult to understand the depth of what this means and how challenging this might be. In Knocking at the Open Door, author R.E. Mark Lee provides an ordinary person view of what being close-up (...) and working together with such a man means, how it challenges one at every turn, and how it causes one to question ceaselessly, even more deeply than one ordinarily would. Lee offers an insightful, candid, and heartfelt narrative that reveals various unknown facets of the eminent world teacher J. Krishnamurti and highlights his distinctive vision for education worldwide. This comprehensive volume brings alive the practical and everyday interactions Lee had with Krishnamurti during a twenty-year period in India and the United Sates. Knocking at the Open Door shares a clear and honest account that demonstrates the challenges of working with Krishnamurti in running a school that is true to the teaching and yet able to function in the reality of modern parental, student, and educational establishment expectations.

The harmful impact of an adverse event ripples beyond injured patients and their families to affect physicians, nurses, and other health care staff that are involved. These “Second Victims” may experience intense feelings of anxiety, guilt, and fear. They may doubt their clinical competence or ability to continue working at all. Some go on to suffer post-traumatic stress disorder and depression.Medical institutions long ignored this problem, preferring to believe that adverse events, or “errors,” occur due to incompetence — the unfortunate (...) work of a few “bad” practitioners who deserve, if anything, a reprimand for their negligence. Study after study has rejected this attribution and shown that adverse events in health care stem primarily from systemic flaws, not “bad apples.” Devastating errors, in other words, can, do, and always will happen in the care of competent, well-trained, and caring practitioners.

Rather than attempting to characterize a relation of confirmation between evidence and theory, epistemology might better consider which methods of forming conjectures from evidence, or of altering beliefs in the light of evidence, are most reliable for getting to the truth. A logical framework for such a study was constructed in the early 1960s by E. Mark Gold and Hilary Putnam. This essay describes some of the results that have been obtained in that framework and their significance for (...) philosophy of science, artificial intelligence, and for normative epistemology when truth is relative.

In presenting the case for according rights and dignity to other creatures, Mark Gold argues that compassion for our fellow humans is a prerequisite for sympathy for animals. He shows how, down the years, animal campaigners have played a crucial role in the struggles against slavery, racism and the oppression of women and children. For those new to the subject, Animal Rights offers a whole new philosophy of life, based on care and compassion for all of creation. For (...) those already converted, here is a heart-warming endorsement of their concerns that demonstrates how a combination of peaceful, determined campaigning and caring consumerism can and does produce results. After answering all the common arguments and misrepresentations levelled against those who campaign for animal rights, Mark Gold moves from theory to practice, offering advice in the second half of the book on the best available alternatives to the many things we do and buy that depend upon animal exploitation. Extensive listings of addresses and sources in both Britain and the USA will prove invaluable to old hands and the newly converted alike. (shrink)

Introduction. There is substantial evidence that patients with delusions exhibit a reasoning bias—known as the “jumping to conclusions” bias—which leads them to accept hypotheses as correct on the basis of less evidence than controls. We address three questions concerning the JTC bias that require clarification. Firstly, what is the best measure of the JTC bias? Second, is the JTC bias correlated specifically with delusions, or only with the symptomatology of schizophrenia? And third, is the bias enhanced by emotionally salient material? (...) Methods. To address these questions, we conducted a series of meta-analyses of studies that used the Beads task to compare the probabilistic reasoning styles of individuals with and without delusions. Results. We found that only one of four measures of the JTC bias—“draws to decision”—reached significance. The JTC bias exhibited by delusional subjects—as measured by draws to decision—did not appear to be solely an epiphenomenal effect of schizophrenic symptomatology, and was not amplified by emotionally salient material. Conclusions. A tendency to gather less evidence in the Beads task is reliably associated with the presence of delusional symptomatology. In contrast, certainty on the task, and responses to contradictory evidence, do not discriminate well between those with and without delusions. The implications for the underlying basis of the JTC bias, and its role in the formation and maintenance of delusions, are discussed. (shrink)

Happy people often fail to elaborate on persuasive arguments, while people in sad moods tend to scrutinise messages in greater detail. According to some motivational accounts, however, happy people will elaborate a message if they believe it might maintain their positive mood. The present research extends this reasoning by demonstrating that happy people will elaborate arguments from message presenters that convey positive hedonic attributes (i.e., source likeability). In a pilot study, we show that happy people believe persuasive messages from a (...) likeable source will be mood maintaining. The results of Study 1 demonstrate that these expectancies have important message-processing implications. In Study 1, sad participants elaborated arguments from both likeable and dislikeable sources, while happy participants only elaborated arguments from a likeable source. Consistent with motivational explanation of these effects, in Study 2, happy participants elaborated arguments from a likeable source when not distracted, but used likeability as a heuristic when distracted with a cognitive-load manipulation. Implications of these results for understanding the effects of mood on processing strategy, limitations, and directions for future research are discussed. (shrink)

BackgroundThe Patient-Centered Outcomes Research Institute is obligated to peer review and to post publicly “Final Research Reports” of all funded projects. PCORI peer review emphasizes adherence to PCORI’s Methodology Standards and principles of ethical scientific communication. During the peer review process, reviewers and editors seek to ensure that results are presented objectively and interpreted appropriately, e.g., free of spin.MethodsTwo independent raters assessed PCORI peer review feedback sent to authors. We calculated the proportion of reports in which spin was identified during (...) peer review, and the types of spin identified. We included reports submitted by April 2018 with at least one associated journal article. The same raters then assessed whether authors addressed reviewers’ comments about spin. The raters also assessed whether spin identified during PCORI peer review was present in related journal articles.ResultsWe included 64 PCORI-funded projects. Peer reviewers or editors identified spin in 55/64 submitted research reports. Types of spin included reporting bias, inappropriate interpretation, inappropriate extrapolation of results, and inappropriate attribution of causality. Authors addressed comments about spin related to 47/55 of the reports.Of 110 associated journal articles, PCORI comments about spin were potentially applicable to 44/110 articles, of which 27/44 contained the same spin that was identified in the PCORI research report. The proportion of articles with spin was similar for articles accepted before and after PCORI peer review.DiscussionJust as spin is common in journal articles and press releases, we found that most reports submitted to PCORI included spin. While most spin was mitigated during the funder’s peer review process, we found no evidence that review of PCORI reports influenced spin in journal articles. Funders could explore interventions aimed at reducing spin in published articles of studies they support. (shrink)

Epistemology -- Power I -- Power II -- Subjectivity -- Resistance -- Critique -- Ethics.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Politics of Practical Reason: Why Theological Ethics Must Change Your Life by Mark RyanDavid ElliotThe Politics of Practical Reason: Why Theological Ethics Must Change Your Life Mark Ryan eugene, or: cascade books, 2011. 229 pp. $20.80If the spirited debate between Stanley Hauerwas and Jeffrey Stout remains front-page news in theological ethics, then Mark Ryan’s subtle and penetrating The Politics of Practical Reason will help (...) keep it there. Ryan argues that practical reason is the hinge of ethical thinking and that it is “political” in the sense of shaping the community or polis. Given this hinge, the pressing question is of course, “Whose practical reason?” To answer this, Ryan probes major contemporary ethicists from Charles Taylor to Alasdair MacIntyre, but the book always circles back to Hauerwas and Stout. Their debate is ultimately decided by proxy, through a mediating philosopher whose work on practical reason Ryan sees both as the gold standard and as the indispensable background for understanding Hauerwas. Expecting this to be MacIntyre, the reader may be surprised—and perhaps even convinced—that the philosopher who best explains and possibly vindicates Hauerwas is in fact Elizabeth Anscombe, Ludwig Wittgenstein’s protégé, close friend, and translator.The book opens with Anscombe’s Intention (1957), which Donald Davidson called “the most important treatment of action since Aristotle.” In it, Anscombe argued that intention presupposes desire and is declared in public language within a context of social practices presupposed for agency to be intelligible. The implication is that we form intentions as members of a community with a particular form of life sustained by social practices. With human desire as its motivating nisus, Ryan insists that intention “is part of the very form of practical reasoning, then, to be political” (144).Having retrieved Anscombe’s model of practical reason, Ryan examines the field of contemporary ethics to see who measures up. Charles Taylor fails to place agents in a particular community, locating us instead in that bloated abstraction called “modernity.” Ryan therefore concludes that Taylor’s is an “ethics for anybody,” which leaves the self finally disembodied (94–98). Stout fares little better due to his refrain that Hauerwas went astray when he abandoned justice talk. Ryan counters that Stout’s sort of justice should be abandoned; lacking a substantive vision of the good and a teleology of freedom, Stout’s justice is reckoned a blind guide who cannot see or say why the polis should pursue one end and not another. Hauerwas, on the other hand, specifies a particular polis within which practical reason can intelligibly function: the church. It has [End Page 218] a substantive vision of the good (i.e., the peaceable kingdom) located in a scriptural narrative displayed by social practices requiring formation in the virtues (119–21). Ryan therefore endorses Hauerwas’s politics of practical reason, indebted to MacIntyre and made possible by Anscombe.I see one lacuna in this otherwise excellent book. Ryan seemingly advocates a pragmatic model of practical reason that is wholly internal to the polis rather than grounded in “truths of human nature as such” (101). This makes Anscombe an uneasy ally. Her “Modern Moral Philosophy” famously proposed a retrieval of virtue that required an overhauled “account of human nature … and above all of human flourishing” (41). This move opened the door for ethical naturalism, perhaps even natural law—both of which Anscombe and the later MacIntyre endorse. But these look suspiciously like what Ryan calls an “ethics for anybody.” So in the end are Anscombe and MacIntyre turncoats, or do Hauerwas and Ryan not follow them far enough? This crucial question remains unanswered.Despite this wrinkle, Ryan’s book is the best intervention in the Hauerwas–Stout debate that we now have. It throws light on Hauerwas, challenges Stout, shows why Anscombe matters, and gives practical reason its generous due. Philosophically deft and charitable in tone, it deserves to be read and studied as a major contribution to the field.David ElliotUniversity of Notre DameCopyright © 2015 Society of Christian Ethics...

Abstract Differing interpretations of the political thought of David Hume have tended to emphasize either conservative, gradualist elements similar to Burke or rationalist aspects similar to Hobbes. The concept of indirect utility as used by Hume reconciles these two approaches. Indirect utility is best illustrated by Hume's conception of justice, in contrast to his conception of benevolence, which yields direct benefits. This understanding of Hume's consequentialism also helps underscore certain egalitarian aspects of Hume's thought.

The contribution of roots to the biology of the whole plant is being reevaluated in the light of classical and recent findings. In addition to their role in water and nutrient uptake and in symbiotic associations, plant roots also synthesize a remarkable variety of secondary metabolites. These chemicals, many of which are used as pharmaceuticals, agrichemicals, flavors, dyes, or fragrances, may help the plant cope with biotic and abiotic stress. Root cultures are being used as experimental systems to explore both (...) root‐specific secondary metabolites and their biological significance. They may also provide future systems for commercial production of plant specialty chemicals. (shrink)

David Lack of Oxford University and V. C. Wynne- Edwards of Aberdeen University were renowned ornithologists with contrasting views of the modern synthesis which deeply influenced their interpretation and explanation of bird behavior. In the 1950's and 60's Lack became the chief advocate of neo-Darwinism with respect to avian ecology, while Wynne- Edwards developed his theory of group selection. Lack 's position was consistent with the developing focus on individual level adaptation, which was a core concept of the modern synthesis. (...) Alternatively, Wynne- Edwards viewed the emphasis on populations as the most important development provided by the modern synthesis. In this paper, I present the development of these two positions and trace their roots in the literature of the synthesis. Through an analysis of Lack 's 1966 critique of Wynne- Edwards I conclude that Wynne- Edwards was, in many ways, justified in his pursuit of group level explanations. (shrink)

Cognition and Temporality argues that both verbal grammar and figural grammar have their cognitive basis in twelve characteristic forms of judgment, distributed among individuals in human populations throughout history. These twelve logical forms are context-free and language-free foundations in our attentional awareness, and shape all verbal and figural statements. Moreover, these types of historical judgment are psychogenetic inheritances in a population, and each serves a distinct problem-solving function in the human species. Through analysis of verbal and figural statements, the author (...) contends, the researcher can find evidence of these forms of judgment, and in turn analyze how the event to which those statements attend is formally constructed by that judgment. This construction guides how the event is assessed, approached, and engaged in the process of problem-solving. Artists and aestheticians in the early twentieth century--including Wassily Kandinsky, Stephen C. Pepper, and Andrew Paul Ushenko--have all posited an inherited attentional perspective in individuals, manifested in the logical correspondence between their distinctive verbal and figural grammars. Cognition and Temporality elaborates these claims, arguing that while the styles of well-known artists and writers are conditioned by the public styles of a particular time period, variations in personal style manifest one's inherited form of judgment, and the characteristic grammars that express that form. Through rigorous visual and stylistic analysis, the author demonstrates the expression of these forms among notable writers and artists across history. The result is a wide-ranging and provocative contribution to phenomenology, aesthetic philosophy, and cultural history. (shrink)

Managed care is evolving in ways that pose unique ethical challenges to those interested in the intersection of clinical and organizational ethics. For example, Disease Management is a form of managed care that has emerged in response to chronic illness. DM is a healthcare management tool that coordinates resources across an entire health care delivery system and throughout the life cycle of chronic disease. Health Maintenance Organizations have reduced some costs in the delivery of acute care, but real cost savings (...) will result only with greater efficiencies in the delivery of costly chronic care. DM is a systematic, population-based approach that identifies persons at risk of chronic ailment, intervenes with specific programs of care, measures clinical and other outcomes, and provides continuous quality improvement. Characterized as a movement to patient-driven services, DM involves a complex web of provider relations. (shrink)

The prolific English poet John Lydgate has been known as the “monk of Bury” since the early fifteenth century. Both his popularity and perceptions of his literary merit have fluctuated wildly since his zenith as the famous laureate of Henry V, Henry VI and Duke Humphrey, but readers have been constant in their association of Lydgate with the Benedictine abbey from which the epithet derives. However, there has been remarkably little examination of the details of Lydgate's existence at Bury: the (...) critical emphasis has been on Lydgate's contact with Lancastrian society rather than on his quotidian life as a monk. “To trace in detail the connection between the Bury library and the characteristic configuration of Lydgate's thought and work, to see how his mind was formed and influenced by the books with which he was in such familiar contact” remains an unfulfilled desire. In particular, given the range of Lydgate's literary and intellectual allusions, it is surprising that there has been no full attempt to compare what we know of Bury's sizeable late medieval library, catalogued in the late fourteenth century by Henry Kirkstede, with Lydgate's poetic output. Likewise, few critics have attempted to trace connections between Lydgate's poetry and the intellectual and cultural atmosphere of a grand Benedictine abbey in the late medieval period. This article, a study of one manuscript from Bury that Lydgate certainly handled and that is typical of the type of book he would have encountered in great numbers in the monastic library, endeavours to reassert the importance to his poetry of the environment in which Lydgate spent most of his life.
