Background: The Directive 2001/20/EC was an important first step towards consistency in the requirements and processes for clinical trials across Europe. However, by applying the same rules to all types of drug trials and transposing the Directive’s principles into pre-existing national legislations, the Directive somewhat failed to meet its facilitation and harmonisation targets. In the field of ethics, the Directive 2001/20/EC conditioned the way of understanding and transposing the “single opinion” process in each country. This led to a situation in (...) which two models of research ethics committees organisation systems exist, being the model in which the “single opinion” is considered to be the decision made by a single ethics committee more effective and simpler in terms of administrative and logistic workload. Method: A survey was conducted in 10 European countries. Members of the European Clinical Research Infrastructures Network working party number 1, with expertise in the field of ethics, responded. Results: There is a major heterogeneity in the composition of ethics committees among the surveyed countries based on the number of members, proportion of experts versus lay members and expertise of the scientific members. A harmonised education of the ethics committees’ membership based in common curricula is recommended by the majority of countries. Conclusions: Despite the efforts for harmonisation of the European Clinical Trial Directive, from an ethical point of view, there remains a plurality of ethics committees' systems in Europe. It is important to comprehend the individual national systems to understand the problems they are facing. (shrink)

To call attention to and motivate action on ethical issues in business or society, messengers often criticize groups for wrongdoing and ask these groups to change their behavior. When criticizing target groups, messengers frequently identify and express concern about harm caused to a victim group, and in the process address a target group by criticizing them for causing this harm and imploring them to change. However, we find that when messengers criticize a target group for causing harm to a victim (...) group in this way—expressing _singular concern_ for the victim group—members of the target group infer, often incorrectly, that the messenger views the target group as less moral and unworthy of concern. This inferred lack of moral concern reduces criticism acceptance and prompts backlash from the target group. To address this problem, we introduce _dual concern_ messaging—messages that simultaneously communicate that a target group causes harm to a victim group and express concern for the target group. A series of several experiments demonstrate that dual concern messages reduce inferences that a critical messenger lacks moral concern for the criticized target group, increase the persuasiveness of the criticism among members of the target group, and reduce backlash from consumers against a corporate messenger. When pursuing justice for victims of a target group, dual concern messages that communicate concern for the victim group _as well as_ the target group are more effective in fostering openness toward criticism, rather than defensiveness, in a target group, thus setting the stage for change.

We explore the developmental paradox of false belief understanding. This paradox follows from the claim that young infants already have an understanding of false belief, despite the fact that they consistently fail the elicited-response false belief task. First, we argue that recent proposals to solve this paradox are unsatisfactory because they (i) try to give a full explanation of false belief understanding in terms of a single system, (ii) fail to provide psychological concepts that are sufficiently fine-grained to capture the (...) cognitive requirements for the various manifestations of false belief understanding, and (iii) ignore questions about system interaction. Second, we present a dual-system solution to the developmental paradox of false belief understanding that combines a layered model of perspective taking with an inhibition-selection-representation mechanism that operates on different levels. We discuss recent experimental findings that shed light on the interaction between these two systems, and suggest a number of directions for future research. (shrink)

The tendency to neglect base-rates in judgment under uncertainty may be as Barbey & Sloman (B&S) suggest, but it is neither inevitable (as they document; see also Koehler 1996) nor unique. Here we would like to point out another line of evidence connecting ecological rationality to dual processes, the failure of individuals to appropriately judge cumulative probability.

The great spiritual traditions unanimously affirm that beyond the boundaried egoic consciousness, typically identified along the psychological spectrum as 'myself' ,lies a more spacious, unboundaried selfhood whose attainment comprises the true fulfilment of our human journey. In this paper, Cynthia Bourgeault expounds that the way toward this state is through nurturing the heart in its foundational role as the seat of non-dual perception.

Metaphor straddles both epistemology and metaphysics. What makes metaphor elusive is intimately bound up in its dual character, a "thing" of the imagination covering both knowledge and reality. Due to its unique position, metaphor is often only understood up to a certain point: we frame it solely as a concern of knowledge or only as a matter of what is. In order to appreciate the impact metaphor has for both of these realms, this paper takes up three constitutive concepts of (...) metaphor (truth, meaning, and reference), and attempts to understand what the content is of each on both sides of the epistemology/metaphysics fence.

The role of interaction in learning is essential and profound: it must provide the means to solve open problems (those only vaguely specified in advance), but cannot be captured using our familiar formal cognitive tools. This presents an impasse to those confined to present formalisms; but interaction is fundamentally dynamical, not formal, and with its importance thus underlined it invites the development of a distinctively interactivist account of life and mind. This account is provided, from its roots in the interactivist (...) biological constitution of life, through the evolution of the dual internal regulatory capacities expressed as intentionality and intelligence, to its expression in self-directed anticipative learning in persons and in science.

Professionalism requires that physicians uphold the best interests of patients while simultaneously insuring just use of health care resources. Current articulations of these obligations like the American Board of Internal Medicine Foundation's Physician Charter do not reconcile how these obligations fit together when they conflict. This is the problem of dual agency. The most common ways of dealing with dual agency: “bunkering”—physicians act as though societal cost issues are not their problem; “bailing”—physicians assume that they are merely agents of society (...) and deliver care typically based on a strongly consequentialist public health ethic; or “balancing”—a vaguely specified attempt to uphold both patient welfare and societal need for judicious resource use simultaneously—all fail. Here I propose how the problem of dual agency might begin to be addressed with rigor and consistency. Without dealing with the dual agency problem and getting more specific about how to reconcile its norms when they conflict, the expectations of professionalism risk being written off as cute, nonbinding aphorisms from the medical profession.

Background Reasonable disagreement about the role awarded to gamete donors in decision-making on the use of embryos created by gamete donation for research purposes emphasises the importance of considering the implementation of participatory, adaptive, and trustworthy policies and guidelines for consent procedures. However, the perspectives of gamete donors and recipients about decision-making regarding research with EGDs are still under-researched, which precludes the development of policies and guidelines informed by evidence. This study seeks to explore the views of donors and recipients (...) about who should take part in consent processes for the use of EGDs in research. Methods From July 2017 to June 2018, 72 gamete donors and 175 recipients completed a self-report structured questionnaire at the Portuguese Public Bank of Gametes. Agreement with dual consent was defined as the belief that the use of EGDs in research should be consented by both donors and recipients. Results The majority of participants were willing to donate embryos for research. Almost half of the donors and half of the recipients considered that a dual consent procedure is desirable. This view was more frequent among employed recipients than among non-employed. Donors were less likely to believe that only recipients should be involved in giving consent for the use of EGDs in research and were more frequently favourable to the idea of exclusive donors’ consent. Conclusions Divergent views on dual consent among donors and recipients indicate the need to develop evidence-based and ethically sustainable policies and guidelines to protect well-being, autonomy and reproductive rights of both stakeholder groups. More empirical research and further theoretical normative analyses are needed to inform people-centred policy and guidelines for shared decision-making concerning the use of EGDs for research.

Dual process theory proposes clusters of features that form two dichotomous groups in cognition. One standing internal issue is defining what the reference of these two dichotomous groups could be in the mind or brain. Does dual process theory speak of two systems, types, minds, modes, kinds or just metaphors? A particular common answer is that differences in clusters of features are evidence of different underlying systems, often called system 1 and system 2. However, the suggestion to abandon the ‘system’ (...) terminology is now common in the literature, but the consequences of doing so need to be addressed. This work reviews and critically discusses previous suggestions. (shrink)

Recent research suggests that the subjective feeling of conscious recollection is uniquely characterized by joint memory for several context features while merely familiar memories lack this property . In the present research we took the novel approach of extending the dual task paradigm to the simultaneous study of subjective retrieval experience and joint memory for two orthogonal context features. While dual task load during encoding lead to reductions in the frequency of the subjective experience of conscious recollection and reductions in (...) overall context memory, joint context memory was not affected. Furthermore, the relation of higher overall context memory for consciously recollected items than for familiar items was preserved even under dual task load. These results have import implications for theories of long-term feature binding and the processes involved in producing the experience of conscious recollection. (shrink)

A sketchy subquantum theory deeply influenced by Wheeler’s ideas (Am. J. Phys. 51:398–404, 1983) and by the de Broglie-Bohm interpretation (Goldstein in Stanford Encyclopedia of Philosophy, 2006) of quantum mechanics is further analyzed. In this theory a fundamental system is defined as a dual entity formed by bare matter and a methodological probabilistic classical Turing machine. The evolution of the system would be determined by three Darwinian informational regulating principles. Some progress in the derivation of the postulates of quantum mechanics (...) from these regulating principles is reported. The entanglement in a bipartite system is preliminarily considered.

The duality of attention is explored by turning our focus to the political and cultural conceptions of automatic attention and deliberate attention, with the former being associated with animality and “uncivilized” behavior and the latter with intelligence and self-mastery. In this article, I trace this ongoing dualism of the mind from early race psychology in the late nineteenth century to twentieth century psychological models including those found in psychoanalysis, behaviorism, neo-behaviorism, and behavioral economics. These earlier studies explicitly or implicitly maintained (...) a deficiency model of controlled attention and other mental processes that were thought to differ between racial groups. Such early models of attention included assumptions that Black and Indigenous peoples were less in control of their attention compared to whites. This racialized model of attention, as seen in the law of economy in the nineteenth century, with similar manifestations in psychoanalysis and neo-behaviorism in the twentieth century, can now be seen in present-day dual-process models as used in current psychological research and behavioral policy. These historical connections show that attention is not a value-neutral term and that attention studies do not stand outside of race and structural racism. (shrink)

Alchemy is central to Jung's hypothesis of the collective unconscious. In this volume he begins with an outline of the process and aims of psychotherapy, and then moves on to work out the analogies between alchemy, Christian dogma and symbolism and his own understanding of the analytic process. Introducing the basic concepts of alchemy, Jung reminds us of the dual nature of alchemy, comprising both the chemical process and a parallel mystical component. He also discusses the seemingly deliberate mystification of (...) the alchemists. Finally, in using the alchemical process as providing insights into individuation, Jung emphasises the importance of alchemy in relating to us the transcendent nature of the psyche. (shrink)

Dual Process Theory is currently a popular theory for explaining why we show bounded rationality in reasoning and decision-making tasks. This theory proposes there must be a sharp distinction in thinking to explain two clusters of correlational features. One cluster describes a fast and intuitive process, while the other describes a slow and reflective one. A problem for this theory is identifying a common principle that binds these features together, explaining why they form a unity, the unity problem. To solve (...) it, a hypothesis is developed combining embodied predictive processing with symbolic classical approaches. The hypothesis, simplified, states that Type 1 processes are bound together because they rely on embodied predictive processing whereas Type 2 processes form a unity because they are accomplished by symbolic classical cognition. To show that this is likely the case, the features of Dual Process Theory are discussed in relation to these frameworks. (shrink)

This paper investigates whether it is fruitful to describe the role culture began to play at some point in the Hominin lineage as pointing to a transition in individuality, by reference to the works of Buss, Maynard-Smith and Szathmáry, Michod and Godfrey-Smith. The chief question addressed is whether a population of groups having different cultural phenotypes is either paradigmatically Darwinian or marginal, by using Godfrey-Smith's representation of such transitions in a multi-dimensional space. Richerson and Boyd's «dual inheritance» theory, and the (...) explanation it provides of the evolution of cooperation in the Hominin lineage, is taken into account to shed light on the way Godfrey-Smith deals with cultural evolution, especially concerning the amount of variation in a population of groups with various cultural phenotypes, the role played by multi-level selection in the evolutionary dynamics of such a population and the adequacy of different modalities of group- reproduction.

The earlier volume in this series dealt with two religions of Indian origin, namely, Buddhism and Jainism. The Indian religious scene, however, is characterized by not only religions which originated in India but also by religions which entered India from outside India and made their home here. Thus religious life in India has been enlivened throughout its history by the presence of religions of foreign origin on its soil almost from the very time they came into existence. This volume covers (...) three such religions—Zoraoastrianism, Judaism, and Islam. In the case of Zoraostianism, even its very beginnings are intertwined with India, as Zoroastrianism reformed a preexisting religion which had strong links to the Vedic heritage of India. This relationship took on a new dimension when a Zoroastrian community, fearing persecution in Persia after its Arab conquest, sought shelter in western India and ultimately went on to produce India’s pioneering nationalist in the figure of Dadabhai Naoroji ( 1825-1917), also known as the Grand Old Man of India. Jews found refuge in south India after the destruction of the Temple by the Romans in 70 C.E. and have remained a part of the Indian religious scene since then, some even returning to Israel after it was founded in 1948. Islam arrived in Kerala as soon as it was founded and one of the earliest mosques in the history of Islam is found in India. Islam differs from the previously mentioned religions inasmuch as it went on to gain political hegemony over parts of the country for considerable periods of time, which meant that its impact on the religious life of the subcontinent has been greater compared to the other religions. It has also meant that Islam has existed in a religiously plural environment in India for a longer period than elsewhere in the world so that not only has Islam left a mark on India, India has also left its mark on it. Indeed all the three religions covered in this volume share this dual feature, that they have profoundly influenced Indian religious life and have also in turn been profoundly influenced by their presence in India.

Rawlsians argue for principles of justice that apply exclusively to the basic structure of society, but it can seem strange that those who accept these principles should not also regulate their choices by them. Valid moral principles should seemingly identify ideals for both institutions and individuals. What justifies this nonintuitive distinction between institutional and individual principles is not a moral division of labor but Rawls’s dual commitments to conventionalism and constructivism. Conventionalism distinguishes the relevant ideals for evaluating institutions from those (...) for evaluating actions, while constructivism explains why this distinction is morally fundamental.

The science of evolution acutely raises the perennial question of humankind’s place in the world. How does the theological anthropology of humans as imago Dei relate to an evolutionary anthropology with human beings derived from ancestral hominid species? Evolutionary biologists disclose ever greater similarities and continuity between animals and humans. Is human distinctiveness simply continuous with other ancestral forms of life or is there any kind of discontinuity? The answers to these questions depend not only on zoological considerations but also (...) on one’s philosophy of nature. The standard anthropology within the Catholic Church is the dual-origin model: the human body originates through evolution, but the human soul is directly created by God. This formulation, however, is not without difficulties, primarily for its seeming Cartesian dualism of a body and soul as distinct substances. This paper develops the anthropology of David Braine who, drawing upon Aristotle, Thomas Aquinas, and Ludwig Wittgenstein, clearly situates humans as animals in great continuity with them. However, as linguistic animals who think in a medium of words, humans have a form of life—a soul—that transcends bodily processes. Braine’s anthropology provides a more coherent anthropology to understand the continuity and discontinuity of the human person in phylogenetic relationship to other species within an evolutionary perspective.

The concept of selecting for a disability, and deafness in particular, has triggered a controversial and sometimes acrimonious debate between key stakeholders. Previous studies have concentrated on the views of the deaf and hard of hearing, health professionals and ethicists towards reproductive selection for deafness. This study, however, is the first of its kind examining the views of hearing children of deaf adults towards preimplantation genetic diagnosis and prenatal diagnosis to select for or against deafness. Hearing children of deaf adults (...) straddle both the deaf and hearing worlds, and this dual perspective makes them ideally placed to add to the academic discourse concerning the use of genetic selection for or against deafness. The study incorporated two complementary stages, using initial, semistructured interviews with key informants as a means to guide the subsequent development of an electronic survey, completed anonymously by 66 individuals. The participants shared many of the same views as deaf individuals in the D/deaf community. The similarities extended to their opinions regarding deafness not being a disability, their ambivalence towards having hearing or deaf children and their general disapproval of the use of genetic technologies to select either for or against deafness.

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.

A coordinate-free formulation is established for (semi) classical particle-field interactions. The exterior language of spacetime chains and De-Rham currents enables the description to include extended strings and membranes besides point particles. Treating physical fields in terms of sections of particular bundles, a unified account of interactions is presented in terms of an intrinsic action principle on a bundle of jets over spacetime. The theory is illustrated by considering the specific model of point particles with intrinsic spin covariantly coupled to theU(1) (...) andSL(2, C) connections describing the electromagnetic and gravitational fields, respectively. The notion of dual spin is examined in this context and coupled equations for this particle-field system are explicitly derived in a local chart. Attention is drawn to the global implications of the theory. (shrink)

What role does language play during attention allocation in perceiving and remembering events? We recorded adults‟ eye movements as they studied animated motion events for a later recognition task. We compared native speakers of two languages that use different means of expressing motion (Greek and English). In Experiment 1, eye movements revealed that, when event encoding was made difficult by requiring a concurrent task that did not involve language (tapping), participants spent extra time studying what their language treats as the (...) details of the event. This „linguistic encoding‟ effect was eliminated both when event encoding was made easier (no concurrent task) and when the concurrent task required the use of language (counting aloud). In Experiment 2, under conditions of a delayed concurrent task of counting aloud, participants used language covertly just prior to engaging in the additional task. Together, the results indicate that language can be optionally recruited for encoding events, especially under conditions of high cognitive load. Yet, these effects are malleable and flexible and do not appear to shape core biases in event perception and memory. (shrink)

This article tracks Corporate Social Responsibility (CSR) as an emergent organizational process that places the employee at its center. Predominantly, research on CSR tends to focus on external pressures and outcomes leading to a neglect of CSR as a dynamic and developing process that relies on the involvement of the employee as a major stakeholder in its co-creation and implementation. Utilizing case study data drawn from a study of a large multinational energy company, we explore how management relies on employees' (...) interaction with CSR as the process of initiation → implementation → maturation develops. Employee involvement grows from a minor element in the CSR initiation stage to a vital contributory factor in CSR's success in the later stages of the process. The article offers new insights into a processual and interactional approach to CSR that accounts for the actions of different actors involved at each stage. Most unusually, it also recognizes the dual impact this has on broader issues concerning the management and involvement of employees through CSR actions, and gaining legitimacy in the eyes of not only external stakeholders but internal too.

A dual-audience signaling problem framework provides a deeper understanding of the perpetuation of group-based inequality. We describe a model of underachievement among minority youth that posits a necessary trade-off between academic success and peer social support that creates a dilemma not typically encountered by nonminorities. Preliminary evidence consistent with the approach is discussed. Such strategic agent perspectives complement the psychological approach put forth by Dixon et al., but with minimal ancillary assumptions.

I want in this paper to enter a protest against the preoccupations of many contemporary philosophers, and to put in a plea for a return to the classical tradition in philosophy. According to this tradition, philosophy is, or at least should be, concerned with the whole conduct of life. It has two main functions, to clarify the wisdom of common-sense people, and to increase it. To put it technically, philosophy, as traditionally conceived, is an activity of self-conscious beings which seeks, (...) among other things, critically to examine the manifestations of human consciousness and the principles which guide human activity; to examine not disinterestedly, but in order to illuminate, to assist, and to reform. Philosophy has, therefore, the dual purpose of revealing truth and increasing virtue. One of the methods traditionally employed for achieving these two purposes consists in the attempt to discover those values which are ultimate in the sense that, while other things are desired for the sake oi them, they alone are desired for their own sakes, to uncover by a process of analysis the values which underlie the judgments commonly passed by contemporary society—as for example, in our own society, the values implied by the judgment that increase of efficiency in slaughter is desirable, especially if combined with a readiness to undertake it whenever the State to which one happens to belong deems the moment expedient for the mass slaughter of the citizens of some other State—and to show how the latter deviate from the former.

Alzheimer's disease (AD) is a neurodegenerative disease exhibiting amyloid beta (Aβ) peptide accumulation as a key characteristic. Autophagy, which is dysregulated in AD, participates in the metabolism of Aβ. Unexpectedly, we recently found that autophagy, in addition to its degradative function, also mediates the secretion of Aβ. This finding adds Aβ to an increasing number of biomolecules, the secretion of which is mediated by autophagy. We also showed that inhibition of Aβ secretion through genetic deletion of autophagy leads to intracellular (...) Aβ accumulation, which enhanced neurodegeneration induced by autophagy deficiency. Hence, autophagy may play a central role in two pathological hallmarks of AD: Aβ amyloidosis and neurodegeneration. Herein, we summarize the role of autophagy in AD with focus on Aβ metabolism in light of the recently established role of autophagy in protein secretion. We discuss potential routes for autophagy‐mediated Aβ secretion and suggest experimental approaches to further elucidate its mechanisms. (shrink)

How can we confront the problems of diminished democracy, pervasive economic inequality, and persistent global poverty?

Human cognitive acts are directed towards objects extended in space of a wide range of different types. What follows is a new proposal for bringing order into this typological clutter. The theory of spatially extended objects should make room not only for the objects of physics but also for objects at higher levels, including the objects of geography and of related disciplines. It should leave room for different types of boundaries, including both the bona fide boundaries which we find in (...) the physical world and the fiat (or human-demarcation-induced) boundaries with which much of geography has to deal. Two distinct axiomatic theories of boundaries are accordingly presented, and the need for both is examined in some detail. The resultant dual framework is shown to have application above all for our understanding of issues involving contact, division, and separation, issues which have posed serious difficulties for the ontological theories of boundaries that have been proposed hitherto.

The paper starts with a distinction between kinds of description that can be proposed for a populational dynamics, including a ‘Darwinian’ description, in terms of variation, inheritance and differential fitness, engaging the entities that make up the relevant population. It follows with a categorization of different kinds of cultural populations and an investigation of the most general conditions that have to be fulfilled for an evolutionary and Darwinian dynamics to take place in those populations, especially in the population comprised by (...) the cultural traits themselves. We make salient some approaches to the evolution in the human lineage, such as dual inheritance theory and memetics, that place cultural evolution at the center of their scenarios. In this way, those approaches contribute to the development of a general theory of cultural evolution, and we compare them, in this respect, with other approaches. Those confrontations grant also illustrations of the analogies between biological evolution and cultural evolution, as well as failures in the analogy. (shrink)

Cognitive psychologists have uncovered a number of natural tendencies to systematic errors in thinking. This paper proposes some ways that intellectual character virtues might help correct these sources of epistemic unreliability. We begin with an overview of some insights from recent work in dual-process cognitive psychology regarding ‘biases and heuristics’, and argue that the dozens of hazards the psychologists catalogue arise from combinations and specifications of a small handful of more basic patterns of thinking. We expound four of these, and (...) sketch how they conspire to produce the myriad biases, heuristics, and illusions. We then offer accounts of two character virtues—self-vigilance and intellectual vitality—and explain how these virtues could help correct our error-prone thinking. The self-vigilant person appreciates her vulnerability to natural epistemic defects, is on the watch for cues to the working of these possible error-makers, and intelligently acts to correct for them. The intellectually vital person is naturally or has learned to be energetic, active, alert, attentive, and inquisitive, contrary to the natural tendency to cognitive laziness. We suggest that these intellectual virtues, like the moral virtues, will cluster in the personality, and will tend to be mutually reinforcing and mutually recruiting, even as each has its own corrective function.

A collection of six essays, including three previously unpublished papers entitled, "Methods of Philosophy," "The Nature of Value," and "The Metaphysical Concept of Space." The target in each case is the whole of technical philosophy; the thesis to be defended is the claim that its separate divisions represent no more than "linguistically contrived intellectual illusions." Along the way, it is argued that the traditional retreat from speculative metaphysics to philosophical analysis is to no avail, for it is claimed that since (...) all philosophy is of a piece, all its parts and methods stand or fall together. We are offered, therefore, the following dual thesis which is both surprising and unique: Philosophy is an ordered whole in structure and method, but the products of philosophical reflection embody nothing more than snares, delusions, and unproductive disputation.—C.

The self‐teaching hypothesis describes how children progress toward skilled sight‐word reading. It proposes that children do this via phonological recoding with assistance from contextual cues, to identify the target pronunciation for a novel letter string, and in so doing create an opportunity to self‐teach new orthographic knowledge. We present a new computational implementation of self‐teaching within the dual‐route cascaded (DRC) model of reading aloud, and we explore how decoding and contextual cues can work together to enable accurate self‐teaching under a (...) variety of circumstances. The new model (ST‐DRC) uses DRC’s sublexical route and the interactivity between the lexical and sublexical routes to simulate phonological recoding. Known spoken words are activated in response to novel printed words, triggering an opportunity for orthographic learning, which is the basis for skilled sight‐word reading. ST‐DRC also includes new computational mechanisms for simulating how contextual information aids word identification, and it demonstrates how partial decoding and ambiguous context interact to achieve irregular‐word learning. Beyond modeling orthographic learning and self‐teaching, ST‐DRC’s performance suggests new avenues for empirical research on how difficult word classes such as homographs and potentiophones are learned.

In lieu of an abstract, here is a brief excerpt of the content:Anorexia and the MacCAT-T Test for Mental Competence:Validity, Value, and EmotionLouis C. Charland (bio)Keywordsmental competence, decisional capacity, anorexia, value, emotionValidity of the MacCAT-THow does one scientifically verify a psychometric instrument designed to assess the mental competence of medical patients who are asked to consent to medical treatment? Aside from satisfying technical requirements like statistical reliability, results yielded by such a test must conform to at least some accepted pretheoretical (...) desiderata; for example, determinations of competence, as measured by the test, must capture a minimal core of accepted basic intuitions about what competence means and what a theory of competence is supposed to do. The concepts of "face validity" and "content validity" are both important here. Face validity "indicates that an instrument appears to test what it is supposed to and that it is a plausible method for doing so" (Portney and Watkins 2000, 82). Content validity "means that the test contains all the elements that reflect the variable being studied" (Portney and Watkins 2000, 83). An adequate instrument for measuring mental competence must at minimum satisfy both of these requirements.What Tan and her colleagues (2006) have shown is that the MacArthur Competence Assessment Tool—Treatment (MacCAT-T) test for mental competence may not be an empirically valid measure of mental competence for some cases of anorexia. The data they report show that "competence," as measured by the MacCAT-T, does not conform sufficiently well with what is wanted of a clinical medical theory of competence. More specifically, the MacCAT-T is deficient in both face and content validity. This result is extremely significant; previous challenges to the validity of the MacCAT-T have often been largely theoretical in nature. My own objection that the MacCAT is inadequate because it omits the influence of emotion is based on a combination of empirical theory (Charland 1998a) and philosophical argument (Charland 1998b). However, it is entirely theoretical in nature. So is my argument that in ignoring emotion the MacCAT misses a crucial contributing ingredient in competence, namely, value (Charland 2001, see especially 136 note 2). Tan's study provides valuable empirical evidence for the second of these challenges, which deals more specifically with value. On the one hand, the study clearly demonstrates that patients sometimes do [End Page 283] base their treatment decisions on reasons derived from values. And on the other hand, it also nicely illustrates the centrality of values—"utilities" or "preferences"—in the decision-making process generally; a basic assumption of standard decision theory for which, paradoxically, there appears to be no satisfactory counterpart in the MacCAT-T model of reasoning and decision making.Thus, values figure among the reasons that patients actually use in reasoning when they weigh the risks and benefits of proposed treatment options. The MacCAT-T must be amended to incorporate this fact if it is to be a satisfactory clinical medical tool. Without such a correction, the concept of mental competence it measures is empirically invalid. At the root of the problem is a clash of intuitions. Tan's data provide convincing evidence that some of the patients who are deemed to be mentally competent by MacCAT-T standards should not in fact be considered competent. Note that the language in which this clash is expressed—"should not in fact"—involves a combination of descriptive and prescriptive elements, reminding us that the concept of competence is dual in nature: it is both prescriptive and descriptive (Freedman 1981). These problems underscore the need for greater clarity about what pretheoretically we want a clinical theory and test of competence to capture. It is of course reasonable to say that such a test must be consistent with major tenets of the relevant case law (Appelbaum 1998). But a legally valid concept of competence of this sort is too thin and arbitrary a foundation on which to build a clinical medical theory of competence. An empirically valid theory and test of the latter sort must incorporate the role of values if it is be truly helpful in medical practice.Value and the MacCAT-TI agree with Tan and her colleagues that some notion of "pathological value" needs to be...

Since the mid-1800s, clergy, doctors, other clinicians, and military personnel who specifically facilitate their work have been designated “non-combatants”, protected from being targeted in return for providing care on the basis of clinical need alone. While permitted to use weapons to protect themselves and their patients, they may not attempt to gain military advantage over an adversary. The rationale for these regulations is based on sound arguments aimed both at reducing human suffering, but also the ultimate advantage of the nation-state (...) fielding non-combatant staff. However, this is sometimes not immediately apparent to combatant colleagues. Clinicians in the armed force are also military officers, owing a “dual loyalty” that can create conflict if their non-combatant status is not well understood. Historical examples of doctors breaching their responsibilities include prioritisation of combat capability over the rights of individual soldiers (as occurred when scarce medical resources were allocated to soldiers more likely to return to battle in preference to those most likely to die without them), use of physicians to facilitate prisoner interrogation, medical research or treatment to enhance physical performance at the expense of health, application of Medical Rules of Eligibility according to factors other than clinical need, provision of treatment contingent upon support for military objectives, and use of medical knowledge to enhance weapons. However, not being a combatant party to a conflict does not imply that the non-combatant clinician cannot act in the national interest. Indeed, by adhering to the same universal ethics as their civilian colleagues, military clinicians provide optimal care to their own troops, facilitate freedom of action in host nations, and build positive international relationships during the conflict and in the post-conflict state.

Starting from simple topological arguments due to Dirac on the classical rotational properties of extended rigid bodies, we abstract the concept of a finite-size spinor (FSS). The FSS is a concept distinct from both point spinors (e.g., electrons) and composite spinors (e.g., nuclei), and suggests a new model for baryons. The FSS offers a natural explanation of “threeness” for the quarks, excludes the existence of free quarks, denies the operational definition of quark spin statistics, and, moreover, leads to the dual (...) model of hadronic interactions.

The dual-deficit model of visual hallucinations (Collerton et al. target article) is compared with the dual-deficit model of auditory hallucinations (Waters et al., in press). Differences in cognitive mechanisms described may be superficial. Similarities between these models may provide the basis for a general model of complex hallucinations extended across disorders and modalities, involving shared (overlapping) cognitive processes.
