A number of studies in the apparent motion literature were examined using the cognitive penetrability criterion to determine the extent to which beliefs affect the perception of apparent motion. It was found that the interaction between the perceptual processes mediating apparent motion and higher order processes appears to be limited. In addition, perceptual and inferential beliefs appear to have different effects on perceived motion optimality and direction. Our findings suggest that the system underlying apparent motion perception has more than one (...) stage and is informationally encapsulated from cognitive factors. (shrink)

We are printing in its entirety the discussion document which sets out a code of professional conduct for nurses published by the Royal College of Nursing in November 1976 together with commentaries by the Assistant Secretary of the British Medical Association, a professor of nursing studies, student nurses and a lawyer. The image of the nurse is still that of one of Florence Nightingale's young ladies or of a member of a religious order who is wholly dedicated to caring for (...) the sick. Today, as this document and the comments upon it show, 'dedication' is still part of the motive which leads a man or woman to become a nurse but in addition, and this is where the public may be ignorant or choose to be ignorant, nursing offers a career where intellectual achievement and the satisfaction of a demanding job bring their proper financial reward and place in the professional community. We are grateful to the Royal College of Nursing for permission to publish this document. (shrink)

This paper examines whether a classical model could be translated into a PDP network using a standard connectionist training technique called extra output learning. In Study 1, standard machine learning techniques were used to create a decision tree that could be used to classify 8124 different mushrooms as being edible or poisonous on the basis of 21 different Features (Schlimmer, 1987). In Study 2, extra output learning was used to insert this decision tree into a PDP network being trained on (...) the identical problem. An interpretation of the trained network revealed a perfect mapping from its internal structure to the decision tree, representing a precise translation of the classical theory to the connectionist model. In Study 3, a second network was trained on the mushroom problem without using extra output learning. An interpretation of this second network revealed a different algorithm for solving the mushroom problem, demonstrating that the Study 2 network was indeed a proper theory translation. (shrink)

Behavior and cognition, once conceived as psychological or interpersonal in origin, are increasingly thought to arise from biology. After investigating the validity of this trend of thinking, the article attempts to interpret what it means to the discipline of psychology. Two main categories of interpretation are discussed. First, this trend could mean that biological factors ultimately underlie traditionally psychological explanations i.e., biological factors are a sufficient condition for understanding behavior and cognition. Second, this trend could indicate that biological factors are (...) important, and perhaps even traditionally overlooked, but are not sufficient in themselves to explain human behavior and cognition i.e., biological factors are necessary conditions among other necessary conditions. The practical and methodological implications of each of these two interpretations are clarified, with a special focus on relevant research limitations. We conclude that the evidence does not bear out a sufficiency thesis and, instead, supports more convincingly a necessity understanding of these trends. (shrink)

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer (...) non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

Hollywood films partially construct how Americans think about education. Recent work on the representation of schools in American cinema has highlighted the role of class difference in shaping school film genres. It has also advanced the idea that a nuanced understanding of American individualism helps to explain why the different class genres are shaped as they are. This article attempts to refine this theoretical approach by focusing on the paradox of individualism, which suggests that individualism must always be dependent on (...) community. We examine 5 films (Rushmore 1988, The Breakfast Club 1985, Mona Lisa Smile 2003, School of Rock 2003, and Stand and Deliver 1988) and argue that, although the values of individualism are certainly celebrated, these films also show, perhaps unwittingly, that the achievements of individualism require robust student communities. We describe how student communities function in these films, what achievements they make possible, and what obstacles they face. (shrink)

Objectives To conduct an independent evaluation of the first phase of the Health Foundation’s Safer Patients Initiative (SPI), and to identify the net additional effect of SPI and any differences in changes in participating and non-participating NHS hospitals. Design Mixed method evaluation involving five substudies, before and after design. Setting NHS hospitals in the United Kingdom. Participants Four hospitals (one in each country in the UK) participating in the first phase of the SPI (SPI1); 18 control hospitals. Intervention The SPI1 (...) was a compound (multi-component) organisational intervention delivered over 18 months that focused on improving the reliability of specific frontline care processes in designated clinical specialties and promoting organisational and cultural change. Results Senior staff members were knowledgeable and enthusiastic about SPI1. There was a small (0.08 points on a 5 point scale) but significant (P<0.01) effect in favour of the SPI1 hospitals in one of 11 dimensions of the staff questionnaire (organisational climate). Qualitative evidence showed only modest penetration of SPI1 at medical ward level. Although SPI1 was designed to engage staff from the bottom up, it did not usually feel like this to those working on the wards, and questions about legitimacy of some aspects of SPI1 were raised. Of the five components to identify patients at risk of deterioration—monitoring of vital signs (14 items); routine tests (three items); evidence based standards specific to certain diseases (three items); prescribing errors (multiple items from the British National Formulary); and medical history taking (11 items)—there was little net difference between control and SPI1 hospitals, except in relation to quality of monitoring of acute medical patients, which improved on average over time across all hospitals. Recording of respiratory rate increased to a greater degree in SPI1 than in control hospitals; in the second six hours after admission recording increased from 40% (93) to 69% (165) in control hospitals and from 37% (141) to 78% (296) in SPI1 hospitals (odds ratio for “difference in difference” 2.1, 99% confidence interval 1.0 to 4.3; P=0.008). Use of a formal scoring system for patients with pneumonia also increased over time (from 2% (102) to 23% (111) in control hospitals and from 2% (170) to 9% (189) in SPI1 hospitals), which favoured controls and was not significant (0.3, 0.02 to 3.4; P=0.173). There were no improvements in the proportion of prescription errors and no effects that could be attributed to SPI1 in non-targeted generic areas (such as enhanced safety culture). On some measures, the lack of effect could be because compliance was already high at baseline (such as use of steroids in over 85% of cases where indicated), but even when there was more room for improvement (such as in quality of medical history taking), there was no significant additional net effect of SPI1. There were no changes over time or between control and SPI1 hospitals in errors or rates of adverse events in patients in medical wards. Mortality increased from 11% (27) to 16% (39) among controls and decreased from 17% (63) to 13% (49) among SPI1 hospitals, but the risk adjusted difference was not significant (0.5, 0.2 to 1.4; P=0.085). Poor care was a contributing factor in four of the 178 deaths identified by review of case notes. The survey of patients showed no significant differences apart from an increase in perception of cleanliness in favour of SPI1 hospitals. Conclusions The introduction of SPI1 was associated with improvements in one of the types of clinical process studied (monitoring of vital signs) and one measure of staff perceptions of organisational climate. There was no additional effect of SPI1 on other targeted issues nor on other measures of generic organisational strengthening. (shrink)

Eyal et al have recently argued that researchers should consider conducting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) human challenge studies to hasten vaccine development. We have conducted (J. L.) and overseen (L. D.) human challenge studies and agree that they can be useful in developing anti-infective agents. We also agree that adults can autonomously choose to undergo risks with no prospect of direct benefit to themselves. However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, for (...) 3 reasons: (1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; (2) autonomous decision making, while necessary, does not override concerns about risk; and (3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the coronavirus disease 2019 (COVID-19) pandemic.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Prominent tuberculosis (TB) actors are invoking solidarity to motivate and justify collective action to address TB, including through intensified development and implementation (D&I) of technologies such as drugs and diagnostics. We characterize the ethical challenges associated with D&I of new TB technologies by drawing on stakeholder perspectives from 23 key informant interviews and we articulate the ethical implications of solidarity for TB technology D&I. The fundamental ethical issue facing TB technological D&I is a failure within and beyond the TB community (...) to stand in solidarity with persons with TB in addressing the complex sociopolitical contexts of technological D&I. The failure in solidarity relates to two further ethical challenges raised by respondents: skewed power dynamics that hinder D&I and uncertainties around weighing risks and benefits associated with new technologies. Respondents identified advocacy and participatory research practices as necessary to address such challenges and to motivate sustained collective action to accelerate toward TB elimination. We present the first empirical examination of bioethical accounts of solidarity in public and global health. Our study suggests that solidarity allows us better to understand and address the ethical challenges that arrest the D&I of new TB technologies. Solidarity lends credence to policies and practices that address the relational nature of illness and health through collective action. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Primacy of God: The Virtue of Religion in Catholic Theology by R. Jared StaudtD. C. SchindlerThe Primacy of God: The Virtue of Religion in Catholic Theology. By R. Jared Staudt. Steubenville, Ohio: Emmaus Academic, 2022. Pp. xii + 409. $49.95 (hardcover). ISBN: 978-1-64585-167-7.Echoing and amplifying a theme from his predecessor, Benedict XVI was known for insisting that the deepest problem of our age, which has not only (...) distorted the culture of the West but has indeed in some ways infected the life of the Church itself, is the forgottenness of God. Recalling the “memory of God” is arguably what Benedict conceived to be the central mission of his papacy, and by that he meant recovering a sense of the primacy of God, not just in matters of private faith, but as a fundamental principle ordering the whole of human existence. In this respect, one can imagine that Benedict would have been heartened to see the new book by R. Jared Staudt, The Primacy of God: The Virtue of Religion in Catholic Theology, which draws not only on Joseph Ratzinger, but also Hans Urs von Balthasar, Christopher Dawson, and, most fundamentally, Thomas Aquinas, to show, indeed, that there is nothing more fundamental than religion.What prompts the need for such an effort is the pervasive sociological reduction of religion in the contemporary imagination to a culturally conditioned set of beliefs and practices that concern God, the divine, or in any event the “afterlife.” In other words, religion is wholly immanentized, understood as an essentially human contrivance, by which man attempts to relate himself to what he takes to be God. It is just this interpretation that lies behind the general assumption of the phenomenon of “religious pluralism”: the world is made up of a potentially infinite number of “different religions,” all of which must be “tolerated” (i.e., must be relegated to a circumscribed social space that renders them more or less politically innocuous) because they offer no rational basis for any sort of arbitration. In contrast to the more typically Protestant response to this “humanistic” reduction of religion, exemplified by Karl Barth, which would insist that Christianity is not “a religion,” Staudt attempts to recover a more robust tradition that recognizes both the deep natural roots of religion and the supernatural distinctiveness of Christianity. To do so, he wisely adopts what he calls a “ressourcement Thomist” approach, but what we might call a genuinely Catholic—and catholic—perspective, namely, one that affirms Thomas Aquinas as a culminating figure of the classical Christian tradition, rather than as one [End Page 685] current of that tradition that defines itself principally in contrast to other currents. In other words, Staudt reads Aquinas in light of Scripture, the Fathers of the Church, and classical philosophy, on the one hand, and in positively disposed engagement with more recent thinkers, such as Ratzinger and Balthasar, on the other. In treating such a fundamental theme as religion, it is especially fitting to attempt to take a fundamental, rather than a “partisan,” approach.The book falls into three basic parts. The first part seeks, in three chapters, to lay out the basic principles of the argument. In chapter 1, Staudt contrasts the opposition Barth presents between religion and the revelation of Scripture, to Aquinas’s interpretation of religion, which integrates philosophy—in this case, Cicero—with Scripture. Chapter 2 considers another objection to Christian religion, this time from the other side, namely, Kant’s attempt to rethink religion from within the limits of reason, and therefore in separation from God. The third chapter sets up the book’s second part by considering religion “as an unfolding of law” (11), specifically, as a matter that, while rooted in natural law, must contend, in its historical enactment, with the distorting reality of sin and the redemption of grace. In other words, religion must be considered in its fundamental expression in the Old Law, and in its fulfillment in the New.The second part of the book investigates in more depth the specifically Christian reality of religion, again in three chapters. Chapter 4 presents religion as exemplified in the... (shrink)

Subjective feelings of familiarity associated with a stimulus tend to be strongest when specific information about the previous encounter with the stimulus is difficult to retrieve . Recognizing: The judgment of previous occurrence. Psychological Review, 87, 252–271.]). When a stimulus has been encountered previously and the circumstances of the encounter cannot be recollected, additional cognitive resources may be directed toward recollection processes; this resource allocation is accompanied by autonomic arousal [Dawson, M. E., Filion, D. L., & Schell, A. M. (...) . Is elicitation of the autonomic orienting response associated with allocation of processing resources?. Psychophysiology, 26, 560–572]. One easily measurable index of autonomic arousal is the skin conductance response . In the present study, participants studied lists of words and then gave recognition ratings to briefly displayed and masked studied and nonstudied test words while their SCRs were monitored. Results revealed a relationship between recognition ratings and the temporal characteristics of the SCR, supporting the idea that feelings of familiarity are indeed “feelings” in that they stem from autonomic arousal associated with cognitive resource allocation.

Court D. Lewis, author of Repentance and the Right to Forgiveness, presents a rights-based theory of ethics grounded in eirenéism, a needs-based theory of rights (inspired by Nicholas Wolterstorff) that seeks peaceful flourishing for all moral agents. This approach creates a moral relationship between victims and wrongdoers such that wrongdoers owe victims compensatory obligations. However, one further result is that wrongdoers may be owed forgiveness by victims. This leads to the “repugnant implication” that victims may be wrongdoers who do not (...) forgive. Author Lewis addresses the “repugnant implication” by showing that victims are obligated to work toward forgiveness, if not forgiveness itself. Critic Gregory L. Bock argues that victims are not the only ones who can forgive, that the personal dimensions of forgiveness are overlooked, and that the force of the “repugnancy implication” may be questioned. Instead of rights-based eirenéism, Bock supports a virtue ethics framework. Instead of rights-based eirenéism, Bock encourages virtue ethics. Critic David Boersema raises questions about the binding nature of relationships, the dependency of flourishing upon forgiveness, and the nature of needs or rights. Boersema also questions the wisdom of a rights-based approach to forgiveness. Critic Jennifer Kling asks whether a rights-based approach is necessary to ground obligations to meet the needs of others: why not an ethics of care? If a rights-based approach is taken, perhaps a wrongdoer is obligated to not make forgiveness a life good. By disengaging this obligation, we avoid constraining a victim’s work toward forgiveness, especially when the wrongdoing is oppressive. Author Lewis responds to these objections. (shrink)

The phrase philosophia perennis is said to have been first used by Leibniz. It has been adopted and freely employed by the Catholic Neo-Thomists, for whom it means a development of the Aristotelianism, modified by strong Neoplatonic elements, which Arabian scholars transmitted to the first Renaissance in the West. It claims also to be a return to the early Christian philosophy of religion, a fusion of Hellenistic and Jewish thought, the latter itself a syncretistic religion with many Persian and other (...) borrowings. The controversy, directed against various modern philosophies, has been conducted with great ability by such writers as Gilson, Maritain, Sheen, Watkin, Dawson and D'Arcy, whose books would perhaps have received more attention from independent thinkers, but for the suspicion which surrounds apparent attempts to revive the methods and inhibitions of the medieval schoolmen. There has been a parallel movement in the Orthodox Eastern Church, represented in Russian by Frank, Bardyaeff, Solovioff and Lossky. These writers are more Platonic and more fearlessly mystical than the Thomists. Origen in the East has more weight than Augustine. (shrink)
