Among the extant masterworks of Roman art, there is probably none that has generated more scholarly debate than the Portland Vase over the interpretation of its elegant frieze. No fewer than forty-four different theories attempting to interpret the scenes on the vase have appeared in the last 400 years. In the main, the theories fall into two categories, those relating the frieze to Greek myth, and those linking the figures to Roman personages. Moreover, there is no consensus whether the frieze (...) is two separate scenes or one continuous story. The obstacle to interpreting the frieze is that all but one of the figures lack identifying attributes. This paper will demonstrate (1) that in lieu of standard iconography, a synthesis of visual and literary tropes in the form of hidden letters, that is, cryptograms, tells the viewer how to read the frieze; (2) that scene A of the frieze illustrates specifically lines 26-30 of Catullus 64 by visually rendering the epithets and tropes used in those lines; (3) that visual reproductions of other tropes in Catullus 64 further substantiate the relationship between frieze and poem; (4) that scene B of the frieze is an intentional aberration from the poem; (5) that there is a complex and unfinished interaction between scenes A and B which the viewer must complete; and (6) that in the final analysis, the frieze duplicates both the theme and central structure of Catullus 64.10 .

Waterfowl--ducks, geese, and swans--are a pervasive, ubiquitous element in Etruscan art, just as they are in well-watered Etruria itself. From the formative Villanovan Period though the terminus of Etruscan culture, waterfowl are regularly depicted in a variety of plastic and glyphic media: pottery, painting, metalwork, and stone. Waterfowl are particularly frequent in funerary contexts. Minimal attention, however, has been accorded this unique branch of avians; waterfowl are generally assumed to have little more than decorative value in the present literature, Nonetheless, (...) it can be shown that ducks, geese, and swans were endowed with social, medicinal, magical, and religious significance in ancient culture and, indeed, in most cultures where waterfowl gather in large numbers. A goodly portion of Etruscan art, as well as comparanda from contemporaneous peoples with whom the Etruscans, directly or indirectly, enjoyed economic and cultural intercourse--the Hellenic lands, Asia Minor and Egypt, central and northern Europe--bears out the preceding statement. This study first examines the natural history of the waterfowl of Etruria, as critical an aspect in their deployment as symbols as are the natural behaviors of the snake and lion in their respective symbolisms. Next, the various roles of waterfowl in medicine, magic and mythology, as well as etymological studies of both Etruscan and Indo-European words for "waterfowl" are investigated and analyzed. Certain aspects of Etruscan conceptions of the afterlife that eventually prove germane are also discussed. Analysis of the combined data helps elucidate the meaning of a number of Etruscan monuments in which waterfowl appear, and simultaneously calls for a reassessment of others, e.g., Villanova and later armor (helmets, pectorals, shield); Orientalizing pieces such as the Regolini-Galassi fibula; Archaic and later bronze mirrors; the Aurora Krater; tomb paintings; and duck askoi. To be sure, there are representations of waterfowl in Etruscan art where the birds serve as decorative elements only -- their beauty is universally admired -- but, as have other cultures, the Etruscans saw considerably more in ducks, geese, and swans than just graceful birds gliding about the waters.

Barnhardt, in “Dissociation: An Evolutionary Interpretation,” makes a case for understanding multiple personality as a “natural”phenomenon resulting from human biological evolution. He also argues that the reason that “multiple personalities” are not encountered more frequently is a result of a social construction encouraging “single” personalities. He concludes that it is from the interaction between the two that ethics derive. In this response I offer an alternative hermeneutic, using memory as the interpretive key, and by introducing Ricoeur’s work on narrative. highlight (...) how Barnhardt’s argument limits us to a “scientific” understanding of MultiplePersonality and thus limits our ability to understand and enact a viable “ethic” of care.

Acute exercise consistently benefits both emotion and cognition, particularly cognitive control. We evaluated acute endurance exercise influences on emotion, domain-general cognitive control, and the cognitive control of emotion, specifically cognitive reappraisal. Thirty-six endurance runners, defined as running at least 30 miles per week with one weekly run of at least 9 miles (21 female, age 18-30 years) participated. In a repeated measures design, participants walked at 57% age-adjusted maximum heart rate (HRmax) (range 51-63%) and ran at 70% HRmax (range 64-76%) (...) for 90 minutes on two separate days. Participants completed measures of emotional state and the Stroop test of domain-general cognitive control before, every 30 minutes during, and 30 minutes after exercise. Participants also completed a cognitive reappraisal task after exercise. Functional near-infrared spectroscopy tracked changes in oxygenated and deoxygenated hemoglobin levels in the prefrontal cortex (PFC). Endurance exercise elevated positive emotion and cognitive reappraisal success. Endurance exercise reduced Stroop response time and test-evoked PFC oxygenation during exercise. Results suggest that even at relatively moderate intensities, endurance athletes benefit emotionally from running both during and after exercise, and task-related prefrontal cortex oxygenation reductions do not appear to hinder prefrontal-dependent cognitive control.

There has been considerable debate in the literature about the relative merits of information processing versus dynamical approaches to understanding cognitive processes. In this article, we explore the relationship between these two styles of explanation using a model agent evolved to solve a relational categorization task. Specifically, we separately analyze the operation of this agent using the mathematical tools of information theory and dynamical systems theory. Information-theoretic analysis reveals how task-relevant information flows through the system to be combined into a (...) categorization decision. Dynamical analysis reveals the key geometrical and temporal interrelationships underlying the categorization decision. Finally, we propose a framework for directly relating these two different styles of explanation and discuss the possible implications of our analysis for some of the ongoing debates in cognitive science.

© 2015 Elsevier Inc.Toxoplasma gondii is a protozoan pathogen in the phylum Apicomplexa that resides within an intracellular parasitophorous vacuole that is selectively permeable to small molecules through unidentified mechanisms. We have identified GRA17 as a Toxoplasma-secreted protein that localizes to the parasitophorous vacuole membrane and mediates passive transport of small molecules across the PVM. GRA17 is related to the putative Plasmodium translocon protein EXP2 and conserved across PV-residing Apicomplexa. The PVs of GRA17-deficient parasites have aberrant morphology, reduced permeability to (...) small molecules, and structural instability. GRA17-deficient parasites proliferate slowly and are avirulent in mice. These GRA17-deficient phenotypes are rescued by complementation with Plasmodium EXP2. GRA17 functions synergistically with a related protein, GRA23. Exogenous expression of GRA17 or GRA23 alters the membrane conductance properties of Xenopus oocytes in a manner consistent with a large non-selective pore. Thus, GRA17 and GRA23 provide a molecular basis for PVM permeability and nutrient access. (shrink)

At the centenary of Frank H. Knight’s Risk, Uncertainty, and Profit, we explore the continuing relevance of Knightian uncertainty to the theory and practice of entrepreneurship. There are three challenges facing such assessment. First, RUP is complex and difficult to interpret. The key but neglected element of RUP is that Knight’s account is not solely about risk and uncertainty as states of nature, but about how an agent’s beliefs about uncertain outcomes and confidence in those beliefs guide their choices. Second, (...) RUP is Knight’s only effort in this area. His subsequent career led elsewhere, so he did not engage with subsequent interpretations of this work. Third, much of the current literature emphasizes that decisions must be different under the two states of nature with a consequent misunderstanding of entrepreneurial agency. This paper addresses each challenge in sequence. First, we explicate Knight’s approach and explain why that approach is murky. Second, as a complement to Knight’s interpretation, we examine Frank P. Ramsey’s approach to subjective probabilities to help clarify Knight’s murky approach. What links Knight and Ramsey is a shared pragmatism about entrepreneurial agency under uncertainty that depends upon the beliefs about, and confidence in, their judgments of possible outcomes. This Knight-Ramsey approach does not require actor’s behaviors to be determined by the class of uncertain environment they face. We focus on the response by the entrepreneur to the existence of uncertainty in all its forms. We argue that this reductive account provides a foundation to examine common problems in management, including managerial hubris, the interaction between entrepreneurs and venture capitalists, and the need for experimentation in advance of new product and venture launches. Third, we critique current literature that favors epistemic purism about the ontology of risk and uncertainty and ignores Knight-Ramsey pragmatism in meeting uncertainty, such as using formal and informal institutions for uncertainty mitigation. Our account locates Frank Knight’s subtleties in entrepreneurial behavior firmly in the literature on entrepreneurial agency a century later. (shrink)

_The Quantum of Explanation_ advances a bold new theory of how explanation ought to be understood in philosophical and cosmological inquiries. Using a complete interpretation of Alfred North Whitehead’s philosophical and mathematical writings and an interpretive structure that is essentially new, Auxier and Herstein argue that Whitehead has never been properly understood, nor has the depth and breadth of his contribution to the human search for knowledge been assimilated by his successors. This important book effectively applies Whitehead’s philosophy to problems (...) in the interpretation of science, empirical knowledge, and nature. It develops a new account of philosophical naturalism that will contribute to the current naturalism debate in both Analytic and Continental philosophy. Auxier and Herstein also draw attention to some of the most important differences between the process theology tradition and Whitehead’s thought, arguing in favor of a Whiteheadian naturalism that is more or less independent of theological concerns. This book offers a clear and comprehensive introduction to Whitehead’s philosophy and is an essential resource for students and scholars interested in American philosophy, the philosophy of mathematics and physics, and issues associated with naturalism, explanation and radical empiricism.

Two key research issues in the field of causal learning are how people acquire causal knowledge when observing data that are presented sequentially, and the level of abstraction at which learning takes place. Does sequential causal learning solely involve the acquisition of specific cause-effect links, or do learners also acquire knowledge about abstract causal constraints? Recent empirical studies have revealed that experience with one set of causal cues can dramatically alter subsequent learning and performance with entirely different cues, suggesting that (...) learning involves abstract transfer, and such transfer effects involve sequential presentation of distinct sets of causal cues. It has been demonstrated that pre-training can modulate classic causal learning phenomena such as forward and backward blocking. To account for these effects, we propose a Bayesian theory of sequential causal learning. The theory assumes that humans are able to consider and use several alternative causal generative models, each instantiating a different causal integration rule. Model selection is used to decide which integration rule to use in a given learning environment in order to infer causal knowledge from sequential data. Detailed computer simulations demonstrate that humans rely on the abstract characteristics of outcome variables to select a causal integration rule, which in turn alters causal learning in a variety of blocking and overshadowing paradigms. When the nature of the outcome variable is ambiguous, humans select the model that yields the best fit with the recent environment, and then apply it to subsequent learning tasks. Based on sequential patterns of cue-outcome co-occurrence, the theory can account for a range of phenomena in sequential causal learning, including various blocking effects, primacy effects in some experimental conditions, and apparently abstract transfer of causal knowledge.

In lieu of an abstract, here is a brief excerpt of the content:Toward Mindful Music Education:A Response To Bennett ReimerSandra L. StaufferIn her book Composing a Life, Mary Catherine Bateson reminds us to acknowledge our antecedents—those who have gone before in whatever way or whatever path.1 I believe we should also acknowledge our co-conspirators—those who have listened to us and wrestled with our ideas. Following Bateson, I wish to recognize the contributions of my teachers and my colleagues, particularly the members (...) of the doctoral seminar at Arizona State University. I am grateful for your contributions to the life of my mind and the words of this morning. For the record, I also want to say that Bennett Reimer is both antecedent and co-conspirator for everyone in this room, and we are indebted to him."The first task of philosophy involves learning to ask a good question," says Walter Feinberg in his essay on the philosophical scholar.2 Reimer asks us, "Who is philosophy of music education for?"—a provocative question indeed. He also gives us an answer: K-12 students.I agree, but not really. How can that be? Imagine this. A music teacher I know, Stephanie, was engaged with some first-grade children in singing songs and moving and reading rhythms. She turned to write on the white board. When she turned back to the children, one boy, Alex, was standing, perfectly still, on his head. What happened next? I will tell you in few minutes. Reimer says, "Philosophical issues are not disconnected to or incidental to musical experience. [End Page 135] They are foundational for musical experience, because one's values, beliefs, desires, preferences, and so forth, directly affect how one engages with music and what one gets from doing it." Abridging those two sentences at my own peril, Reimer appears to be saying that philosophical issues are foundational to musical experience.That idea works for me only if I am standing, figuratively and metaphorically, not literally, on my head. It seems to me that experience is the foundation of philosophy or, put another way, that one's philosophy derives from one's experiences; the richer the experiences, the richer the philosophy. A philosophy based on limited or weak experience is a limited or weak philosophy. This, however, is only surface-level logic for a deeper epistemological question—where does one's philosophy come from? If I take the Deweyan perspective that philosophy derives from experience, then surely I am obligated, in this forum, to define my terms—particularly "experience." It would be easy to say that experience means making music and listening to music, and surely it does. By experience, however, I mean not only these actions—the doing of music—but also thinking, or what Ellen Langer calls mindfulness.3 Langer describes mindful learning as having three characteristics: "the continuous creation of new categories; openness to new information; and an implicit awareness of more than one perspective."4 I like how Robert Duke articulates the same idea: "Teach things that are intellectually interesting and functionally valuable."5 Engage students not just in doing, but also in thinking—in mindful learning. Rich experience makes for rich philosophy. If we are talking about music education at all levels that is not only participatory, but also mindful, then I am all for it.Reimer asks a second question: how are we to accomplish the teaching of philosophy to K-12 students? I want to know what we are trying to accomplish. Are we trying to teach the content of philosophy or are we trying to help students develop their own abilities to think about their experiences as musicians, whether as listeners or as music makers, in whatever contexts they find themselves? The former seems to be a reification of philosophy in which I am not eager to engage most K-12 students. I hope we are aiming for the latter. If so, then our task is to provide rich and mindful experiences in every music setting. Our task is to model the disposition of a philosopher—one who asks questions, is curious, and is engaged in the life of the mind.This seems so obvious. Why aren't we doing it already? There...

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

RationaleSurrogates of critically ill patients often have inaccurate expectations about prognosis. Yet there is little research on how intensive care unit clinicians should discuss prognosis, and existing expert opinion-based recommendations give only general guidance that has not been validated with surrogate decision makers.ObjectiveTo determine the perspectives of key stakeholders regarding how prognostic information should be conveyed in critical illness.MethodsThis was a multicenter study at three academic medical centers in California, Pennsylvania, and Washington. One hundred eighteen key stakeholders completed in-depth semistructured (...) interviews. Participants included 47 surrogates of adult patients with acute respiratory distress syndrome; 45 clinicians working in study ICUs, including physicians, nurses, social workers, and spiritual care providers; and 26 experts in health communication, decision science, ethics, family-centered care, geriatrics, healthcare disparities, palliative care, psychology, psychiatry, and critical care.Measurements and main resultsThere was broad support among surrogates for existing expert recommendations, including truthful prognostic disclosure, emotional support, tailoring the disclosure strategy to each family's needs, and checking for understanding. In addition, stakeholders offered suggestions that add specificity to existing recommendations, including: In addition to conveying prognostic estimates, clinicians should help families "see the prognosis for themselves" by showing families radiographic images and explaining the clinical significance of physical manifestations of severe disease at the bedside. Many physicians did not support using numeric estimates to convey prognosis to families, whereas many surrogates, clinicians from other disciplines, and experts believed numbers could be helpful. Clinicians should conceptualize prognostic communication as an iterative process that begins with a preliminary mention of the possibility of death early in the ICU stay and becomes more detailed as the clinical situation develops. Although prognostic information should be initially disclosed by physicians, other members of the multidisciplinary team-nurses, social workers, and spiritual care providers-should be given explicit role responsibilities to reinforce physicians' prognostications and help families process a poor prognosis emotionally.ConclusionsFamily members, clinicians, and experts identified specific communication behaviors that clinicians should use to discuss prognosis in the critical care setting. These findings extend existing opinion-based recommendations and should guide interventions to improve communication about prognosis in ICUs. (shrink)

The posterior cortex, hippocampus, and prefrontal cortex in the Leabra architecture are specialized in terms of various neural parameters, and thus are predilections for learning and processing, but domain-general in terms of cognitive functions such as face recognition. Also, these areas are not encapsulated and violate Fodorian criteria for modularity. Anderson's terminology obscures these important points, but we applaud his overall message.

Late in 1990, the Center for the Study of Ethics in the Professions at Illinois Institute of Technology (lIT) received a grant of more than $200,000 from the National Science Foundation to try a campus-wide approach to integrating professional ethics into its technical curriculum.! Enough has now been accomplished to draw some tentative conclusions. I am the grant's principal investigator. In this paper, I shall describe what we at lIT did, what we learned, and what others, especially philosophers, can learn (...) from us. We set out to develop an approach that others could profitably adopt. I believe that we succeeded. (shrink)

How do educators better reach their students, better capture their attention and imagination without sacrificing scholarship? Teachable Moments: Essays on Experiential Education examines the pedagogy of Prescott College, a school that has embraced experiential education and been finding success with it for over thirty years. These essays—from scholars in fields as wide ranging as religious studies, environmental science, psychology, dance, literature, adventure education, and peace studies—examine the challenges and, ultimately, the rewards of student-centered education.

To explore the realm of creativity, we will make use of the concept of instauration as articulated in the work of Étienne Souriau. Although infrequently used, the word remains extant in English, with agreement among dictionaries that the primary definition is the action of restoring or renewing, with a secondary meaning of instituting or founding. While both senses are at play in Souriau’s thought, it is perhaps the tension between the two that is predominantly in question, akin to what we (...) describe as open containment. We think instauration, as institutive renewal, in dialogue with Merleau-Ponty’s late use of the term aesthesiology to further elaborate the process of creating as a return to the wonder that is aesthesis, the affectively and sensually apprehended opening onto and entanglement with what is. Merleau-Ponty extends aesthesiology as the science of the sense organs themselves into a philosophical organology for ontology. His use of aesthesiology and Souriau’s use of instauration constitute efforts to offer sufficient conceptual containment to be able to say the contingent and ambiguous open of ongoing originating, even while both thinkers strive not to institute any final closure by this very act of naming. This is the inevitable tension of writing philosophic creation.Pour explorer le royaume de la créativité, nous utilisons ici le concept d’instauration tel qu’il a été articulé dans l’oeuvre d’Étienne Souriau. Quoique utilisé rarement, ce terme est attesté dans la langue anglaise. Les dictionnaires anglais accordent que sa définition principale désigne une action de rétablissement ou de renouvellement, avec un sens secondaire d’institution ou fondation. Si les deux sens sont à l’oeuvre chez Souriau, c’est peut-être la tension entre eux qui y est surtout patente. Nous pensons ici l’instauration, entendue comme renouvellement instituant, en dialogue avec l’idée d’esthésiologie telle que Merleau-Ponty la comprend à la fin de son oeuvre. Il utilise cette notion pour développer sa conception du processus de création comme retour à l’étonnement que produit l’áisthesis. L’áisthesis est en effet l’ouverture, affective et sensible, et l’entrelacs, affectif et sensible, à ce qui est. Merleau-Ponty prolonge ainsi l’esthésiologie entendue comme science des organes sensibles, vers une organologie philosophique à visée ontologique. L’usage de l’esthésiologie chez Merleau-Ponty et l’usage de l’instauration chez Souriau constituent des efforts vers une maîtrise conceptuelle suffisante pour pouvoir dire l’ouverture continue, contingente et ambiguë de l’originaire – bien que les deux penseurs ne visent pas à instaurer une clôture finale à partir de l’acte nominatif. Telle est la tension inévitable qu’on rencontre lorsqu’on cherche à écrire la création philosophique.Utilizzeremo in queste pagine per esplorare il regno della creatività il concetto di “instaurazione” così come si trova articolato nell’opera di Étienne Souriau. Benché impiegato raramente, questo termine è attestato anche nella lingua inglese. I dizionari inglesi danno come significato principale quello di un’azione di ristabilimento o rinnovamento, a cui si aggiunge un significato secondario di istituzione o fondazione. Se è vero che entrambi i significati sono all’opera in Souriau, è d’altra parte ancor più evidente la loro tensione. Proporremo qui di pensare l’instaurazione, intesa come rinnovamento istituente, in dialogo con l’idea di estesiologia così come la intende Merleau-Ponty alla fine del suo percorso. Egli usa questa nozione per sviluppare la sua concezione del processo creativo come ritorno allo stupore dell’áisthesis, cioè dell’apertura affettiva e sensibile, e dell’intreccio affettivo e sensibile, a ciò che è. Merleau-Ponty prolunga così l’estesiologia come scienza degli organi di senso in direzione di un’organologia filosofica orientata ontologicamente. L’indagine sull’estesiologia condotta da Merleau-Ponty e l’uso del concetto di instaurazione in Souriau costituiscono così altrettanti sforzi di dire concettualmente l’apertura continua, contingente e ambigua dell’originario – benché sia chiaro che i due pensatori non intendono raggiungere in alcun modo, con questo dire concettuale e con questa scelta lessicale, una qualsiasi “chiusura” della questione. Tale è infatti la tensione inevitabile cui ci si ritrova esposti quando si tenta di scrivere la creazione. (shrink)

This book evaluates the claim that in order to explore the changing social foundations of global power relations today, we need to include in our analysis an understanding of global civil society, particularly if we also wish to raise ethical questions about the changing political and institutional practices of transnational governance. The authors engage directly with the notion of global civil society in order to examines the ethical, social, and political conditions that make certain kinds of globalizing practices a reality (...) today. They explore and utilize the normative dimensions of the civil discourse to further debate about the meaning of citizenship in a world of multi-level governance, as well as the changing characteristics of political community and democracy. Bridging the normative concerns of political theorists with the historical and institutional focus of scholars of international relations and international political economy, this book will be of broad interest to students and researchers concerned with international relations, civil society, global governance and ethics.
