Most computational theories of cognition lack a representation of physiology. Understanding the cognitive effects of compounds present in the environment is important for explaining and predicting changes in cognition and behavior given exposure to toxins, pharmaceuticals, or the deprivation of critical compounds like oxygen. This research integrates physiologically based pharmacokinetic (PBPK) model predictions of caffeine concentrations in blood and tissues with ACT-R's fatigue module to predict the effects of caffeine on fatigue. Mapping between the PBPK model parameters and ACT-R model (...) parameters is informed by the neurophysiological literature and established associations between ACT-R modules and brain regions. The results from three such parameter mappings are explored to explain observed data from sleep-deprived participants performing the psychomotor vigilance test with and without caffeine. Predicted caffeine concentrations in the brain are used to modulate procedural parameters in the fatigue module to explain caffeine's effects on multiple performance metrics. (shrink)

Tim Lewens aims to understand what it means to take an evolutionary approach to cultural change, and why it is that these approaches are sometimes treated with suspicion. While making a case for the value of evolutionary thinking for students of culture, he shows why the concerns of sceptics should not dismissed as mere prejudice, confusion, or ignorance. Indeed, confusions about what evolutionary approaches entail are propagated by their proponents, as well as by their detractors. By taking seriously the problems (...) faced by these approaches to culture, he shows how such approaches can be better formulated, where their most significant limitations lie, and how the tools of cultural evolutionary thinking might become more widely accepted.

Were the Greek novels titled according to a consistent convention? This article confronts the view that the original titles were always historiographical in form (Assyriaka, Lesbiaka, Aithiopika, etc.) and that readers were thus steered to expect, in the first instance, realistic narrative. Examining the evidence in detail, it argues that the formula the novels were likeliest to have shared was ta kata + girl's name (or girl's + boy's names). On this basis, it is concluded that what the titles of (...) the novels promised was primarily invasive narratives of private life. (shrink)

The presumption is that a broker executing a stock trade for a retail investor will get the investor the best possible price execution for the transaction. In fact, the broker often sells the retail investor’s trade to an intermediary for cash payment. The broker’s motivation to generate dealer profits seems to overcome the broker’s fiduciary responsibility to obtain the best execution price for the customer, raising ethical questions. Purchasers and internalizers of order flow in the market may cause prices quoted (...) on the NYSE to deteriorate, making all investors worse off. (shrink)

Philosopher Ewa Majewska's impressive new book aims at nothing less than changing the structures of thinking and feeling that shore up the liberal vision and practice of the public sphere. This structural shift is proposed to resist and ultimately block the rise of contemporary fascism. This seems brave and immense but because Majewska's methods are not revolutionary but rather rest in the quotidian, it comes to be seen as credible. It is, of course, a necessary goal, so it is reassuring (...) that her arguments provide tools for transformation.Majewska's argument rests on a challenge to the classic liberal division between public and private, and insists that solidarity should rather be a core model for politics. The... (shrink)

Zusammenfassung Der Beitrag setzt sich kritisch mit einer Schlüsselkategorie der Weber’schen Soziologie auseinander: dem Charisma. Dieser Kategorie war und ist bis heute ein großer kommunikativer Erfolg beschieden, hat also eine breite Rezeption in der internationalen Forschung erfahren. Dieser Umstand bedeutet allerdings nicht, dass Webers Charisma-Begriff keine Kritik erfahren hätte. Ganz im Gegenteil. Fast jeder Weber-Kenner hat auch Kritik an der fraglichen Kategorie geäußert. Dieser gilt es in dem Beitrag nachzuspüren, um zu einer Erhöhung des Problembewusstseins der Forschung hinsichtlich der Rede (...) vom ‚Charisma‘ beizutragen. Zugleich wird der Versuch unternommen, die fragliche Kategorie differenztheoretisch und relational zu wenden, um somit ihr heuristisches Potential zu schärfen. (shrink)

The context for these interviews was a seminar [Peter Gratton] conducted on speculative realism in the Spring 2010. There has been great interest in speculative realism and one reason Gratton surmise[s] is not just the arguments offered, though [Gratton doesn't] want to take away from them; each of these scholars are vivid writers and great pedagogues, many of whom are in constant contact with their readers via their weblogs. Thus these interviews provided an opportunity to forward student questions about their (...) respective works. Though each were conducted on different occasions, the interviews stand as a collected work, tying together the most classical questions about “realism” to ancillary movements about the non-human in politics, ecology, aesthetics, and video gaming—all to point to future movements in this philosophical area.

Feelings of shame are normal when suffering guilt from sin, but the church too often gives congregants a simplistic “shame script,” which paints God only as an angry or disappointed judge and so circumvents a lasting relational intimacy with him. For those who struggle to approach God because of the shame they suffer from past sins and current temptations, recent psychological research provides some insight. I demonstrate: those who agonize over feelings of shame need new “cultural scripts” and “life scripts” (...) by which to flourish, new narratives wherein a healthier view of God, self and community might emerge. The starting point is a proper biblical script of God as our Father, a vision of God the Father that resists one-dimensional notions of divine anger and disappointment. A more robust, intimate and grace-filled concept of God the Father, in other words, provides relief to the sufferers of unhealthy shame. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Sweating the Small StuffTim CunninghamAs an emergency nurse, I often do not notice the small stressors as compared to the loads of intense physical and emotional suffering I witness while working at a level–one–trauma center. The horrendous deaths and injuries caused by gun violence, motorized vehicles, people in emotional distress and those suffering from chronic diseases build up on the mind as a veritable ‘scrapbook of nightmares.’ Emergency providers (...) know, in taking on this profession, that this is ‘all in a day’s work.’ Consequently, we put our selves at risk for emotional burnout as we bear witness to profound suffering while trying to improve lives.I see the traumas, the end–of–life decision making thrust upon families amidst a medical crisis and the other aspects of emergent suffering as bails of hay, against which I tried to build coping mechanisms in order to experience them but also be able to let go. For the most part I am confident to report that I have been able to work through major traumatic situations without belaboring the emotional residue. What I have failed to notice though are not the bails of hay, but individual straws of which they are made.A straw that nearly broke my back came to my pediatric emergency room as a 9–year–old girl who was involved in a low speed motor vehicle collision. She was restrained in the passenger seat; and although she was walking at the scene and crying, she was backboarded by EMS and placed in a cervical spine brace. On arrival to our emergency department she presented with normal vital signs and mutation. Her only complaint was diffuse abdominal pain. We preformed a FAST (Focused Assessment with Sonography for Trauma) exam, which was negative for free abdominal blood. Despite our efforts to make the patient comfortable, we were unable to ease her pain. The patient reported that her pain decreased after we took her off the backboard, but she still did not feel herself.Our attending and resident physicians decided that this child should have an abdominal computed tomography scan (CT) to rule out organ damage with subsequent bleeding. According to hospital protocol, this decision was within our standards of care. I stood by the family when the physician team discussed the plan of care and noticed the parents’ collective body language, which was troubled. I left the room with the physicians but not long after, the family subtly requested that I speak with them.The family was concerned about the radiation to which their child would be exposed. At the same time, they too were concerned about her abdominal pain and understood that a CT could confirm serious abdominal injury. They knew the gravity of the worst–case scenario and wanted to do what was best for their child.The mother asked me if this girl were my child what would I do.My first thought was: No CT, go home, watch her and return if symptoms worsen. My second thought conflicted with the first as I realized this was instruction that fell out of protocol differing from the opinions of the physician team. I paused before responding and found myself sputtering some pointless information about CT scans and mechanisms of injuries sustained from car accidents—I [End Page E9] was filling space, avoiding their question as I pondered the best answer.The girl’s parents told me that one was leaning towards the CT and the other against, they wanted my advice to make a decision. They pressed me saying, “What would you do.” Although I felt an uneasiness and nausea in that moment, I told them my truth, which was that I would go home without the CT.The family appeared relieved and I felt the sensation of stress leaving my body as if I had just taken a deep breath. Contented, but a daughter still with abdominal pain, the family left that evening with specific instructions to watch for adverse symptoms.In that moment, I felt like I had done the right thing but by the end of my shift I left work questioning my choice. I lost sleep that night because of... (shrink)

This study analyzed 16 potential ethics-related problems associated with use and abuse of video news releases (VNRs) by public relations practitioners and electronic journalists. Causes and possible solutions to the problems were suggested and model ethics code guidelines were developed. Moral rules, moral ideals, theories of ethics, public relations theories, and electronic journalism theories were used to provide a general foundation for the analysis. A more specific foundation was provided by guidelines from a variety of media codes of ethics.

“There is a familiar trio of reactions by scientists to a purportedly radical hypothesis: (a) “You must be our of your mind!”, (b) “What else is new? Everybody knows _that_!”, and, later—if the hypothesis is still standing—(c) “Hmm. You _might _be on to something!” ((Dennett, 1995) p. 283).

This paper is a response to Ted Toadvine’s article “Gestalts and Refrains: On the Musical Structure of Nature,” in Environmental Philosophy 2.2 (2005). We propose a more generous interpretation of Naess’s gestalt ontology, one that we believe mitigates Toadvine’s criticisms. Gestalt ontology and refrain ontology offer two different yet compatible ontologies for environmental philosophers searching for viable alternatives to scientific reductionism. Encouraging many ontologies also encourages a rich philosophical pluralism.

Stone and Valentine presented masked 17 ms faces in simultaneous pairs of one famous and one unfamiliar face. Accuracy in selecting the famous face was higher when the famous person was regarded as “good” or liked than when regarded as “evil” or disliked. Experiment 1 attempted to replicate this phenomenon, but produced a different pattern of results. Experiment 2 investigated alternative explanations and found evidence supporting only the effect of response latency: responses made soon after stimulus onset were more accurate (...) to liked than to disliked faces, whereas responses made after a longer delay were equally accurate to disliked faces. It appears that the effect of negative valence was corrected within the space of a few hundred milliseconds. Experiment 3, using an affective priming paradigm, supported the concept that an early-arising effect of valence is corrected if it is misleading to the directed task. (shrink)

This paper builds on the work of Tuffrey-Wijne et al. and explores the issue of vulnerability and persons with disabilities in relation to Euthnasia and Assisted Dying. The commentary draws on both the literature and on case examples from Canada. Specifically, it considers the issue of EAS as an alternative to, or substituted for, appropriate disability supports. Secondly, it considers the issue of the devaluation of disabled lives in general and within health care practice and ethics. It concludes that current (...) safeguards are inadequate and that as EAS regimes become more permissive the risk to disabled persons will increase. (shrink)

Many Americans don't hold journalists in very high regard these days, and sports journalists are often viewed in the least favorable light. The general public does not perceive any visible, unified, and concerted effort among sportswriters to practice their craft in a consistently ethical manner. Efforts to upgrade the craft include the Associated Press Sports Editors ethical guidelines, which cover freebies, moonlighting, community involvement by sports journalists, and commercial sponsors of sporting events. This study examines the APSE code and suggests (...) additional, more specific, and enforceable guidelines in ten areas: freebies, moonlighting, newsgathering methods, news sources, direct quotes, privacy, gambling, special interests, self?interests, and involvements. Sports journalists should be as ethically accountable as any other journalists, the author concludes. (shrink)

In this article I provide a Thomistic truthmaker principle. Although Aquinas himself never provides a truthmaker principle, he does say things that show he thought many truths require truthmakers, or, in other terms, that truths have an ontological grounding. That truths are somehow grounded or explained by reality is an important aspect of Thomistic thought. The principle I provide could be affirmed by someone with Thomistic tendencies: it is consistent with Aquinas’ thought and makes sense of some peculiar aspects of (...) his writings. In what follows, I will argue that a Thomistic truthmaker principle should require all truths about being to have a truthmaker at any time that they are about. (shrink)

Das Motiv der Gegenüberstellung von Kind und Erwachsenem ist formal wie inhaltlich wesentlich für Platons Schriften. Mit dem Kind ist auch ein Seelenzustand des Erwachsenen gemeint, der die eigentliche Entwicklung seiner Seele zur personalen und souveränen Identität noch anfangen muss. Auf diesen Anfangs- und Entwicklungsgedanken hin sind Platons Dialoge konzipiert: Die Verschränkung von Logos und Mythos ist Darstellung und Anleitung einer Identitätsfindung, d. h. einer Auffindung des Ichs, das sich selbst formt, anstatt, getrieben von seinem Werdegang, dem Vorgegebenen zu folgen. (...) Ein zweites Leitmotiv bezieht sich auf diese Selbstformung und Entwicklung: die Gegenüberstellung von Mensch und Gott. Als Gegenentwurf zu einer veränderlichen Welt dient das Göttliche vor allem dazu, diese materielle Welt als einzigen Ort von freier Selbstzeugung zu erkennen. (shrink)

The Adaptive Toolbox framework specifies heuristics for choice and categorisation that search through cues in previously learned orders (Gigerenzer & Todd, 1999). We examined the learning of three cue parameters defining different orders: discrimination rate (DR) (the probability that a cue points to a unique choice), validity (the probability of correct choice given that a cue discriminates), and success (the probability of correct choice). Success orderings are identical to those by expected information gain (Klayman & Ha, 1987). In two experiments, (...) participants made choices in real-world environments with objective outcome criteria. Participant ratings indicated some appropriate parameter learning when the relevant cue parameter values were highly dispersed. Rated orders of cue validity and DR were less distinct than the objective orders—learning one parameter may be biased towards success by variation in the other. Success ratings capture the variation in validity and DR as well as participants' perception of these parameters. (shrink)

The notion of capacity implicit in the Mental Capacity Act is subject to a tension between two claims. On the one hand, capacity is assessed relative to a particular decision. It is the capacity to make one kind of judgement, specifically, rather than another. So one can have capacity in one area and not have it in another. On the other hand, capacity is supposed to be independent of the ‘wisdom’ or otherwise of the decision made. (‘A person is not (...) to be treated as unable to make a decision merely because he makes an unwise decision.’ Department of Constitutional Affairs 2005, section 1). One may have capacity even if the decision one arrives at is seen as unwise by one’s doctor. In this short note, I explore this .. (shrink)

The spiritual torsion and material complexity so characteristic of Baroque aesthetics is something that extends to (or perhaps, better, issues from) the intension of the term itself. This much is evident in the sense that, since the twentieth century, various projects have proposed such notions as a medical-baroque, a postcolonial-baroque, and a digital-baroque. Beyond any given object of analysis, then, in this way the Baroque adduces the concepts by which any inquiry into objects might take place. As such, the Baroque (...) can be said to be that which signals the ongoing relation of thought to the world, of ‘the inside’ to ‘the outside’ (while at the same time problematising the priority of either side over the other). Indeed, following certain post-Kantian readings of Leibnizian philosophy, the Baroque is to be regarded not so much as something to be understood but rather as a frenzied development of the understanding itself.

Overview of this minor Socratic school, including their skepticism and hedonistic ethics.

This article examines the utopian vision present in the eponymous work by Thomas More and in the early Anabaptists. In the light of the discussion on the power and dangers of utopian thinking in liberation theology it seeks to show how More struggled with the tension between the positive possibilities of a different world and the destructive criticism of the present reality. A similar tension is found in early Anabaptist practices, especially in terms of their relationship to the state and (...) their practice of commonality of goods. The article shows that that all attempts to reduce visions of a better world to a particular setting end up as ideological. (shrink)
