Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes of an Epidemiology Masters program in Lima, Peru, and describes the implementation (...) and outcomes of a multifaceted, “zero-tolerance” policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events’ severity, penalties included course failure and separation from the program. Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: intensified research integrity and scientific writing education, a stepwise, cumulative writing process; honor codes; active search for plagiarism in all academic products; and a “zero-tolerance” policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it. (shrink)

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.

I defend a slightly modified version of geach's rule r, I.E., That although both a and b are g, It is possible for a to be the same f as b and a different h than b, Provided that the question whether a and b are the same g is undecidable. Answering those who object to relative identity I claim that they tacitly adhere to a false fregean view, I.E., That one cannot use a singular term to denote an entity (...) x if it is not true that for every y, X=y or not x=y. I show, However, That such terms are, And must be, Used by every empirically oriented language with finite or infinite predicative arsenal, And hence relative identity is more handy than absolute identity. Finally I give a version of leibniz's law for relative identity. (shrink)

R. E. Ewin has argued that corporations are moral persons, but Ewin describes them as being unable to think or to act in virtuous and vicious ways. Ewin thinks that their impoverished emotional life would not allow them to act in these ways. In this brief essay I want to challenge the idea that corporations cannot act virtuously. I begin by examining deficiencies in Ewin's notion of corporate personhood. I argue that he effectively reduces corporations to the status of incompetent (...) patients. I shall make use of a richer notion of corporate personhood as I explore the logical relationship between corporate action and the quality of the corporate emotional life. After discussing an alternate methodology for making moral assessments of action I consider briefly two corporate disasters: the crash on Mt. Erebus, the Imperial Foods plant fire. These cases are used to show the inadequacy of Ewin's thesis that only corporate managers are capable of displaying vice. (shrink)

O ceticismo é por vezes descartado como uma doutrina absurda e merecedora do seu lugar distante na antiguidade. Nada poderia ser menos correto. O ceticismo continua extremamente relevante para o pensamento filosófico e científico de hoje, servindo como um lembrete de que a sabedoria não é barata nem segura. Nesse texto, o meu objetivo principal é reproduzir o raciocínio das discussões clássicas sobre o ceticismo, mas de uma maneira coloquial e contemporânea. Após seguir as linhas de pensamento de Sexto (...) Empírico, René Descartes, e David Hume, eu vou extrair e identificar claramente as teses centrais que marcam as suas ideias. A minha intenção, porém, não é a de sugerir que as suas teses são auto-evidentes, ou incontestáveis, ou até hoje ainda incontestadas. Muito pelo contrário. A minha intenção é produzir um aperitivo ao debate e um convite a discussão. (shrink)

Before I respond to the four essays that have each offered valuable feedback on my Comprehensive Commentary on Kant’s ‘Religion within the Bounds of Bare Reason‘ (hereafter CCKR), [1] a meta-critical question calls for an answer: Why was yet another commentary on Kant’s book, Religion within the Bounds of Bare Reason (hereafter RGV), needed in 2015, [2] given the unprecedented fact that each of the three previous years had seen the publication of a commentary on the same book? The short (...) answer is that work on my commentary began several years before James DiCenso (2012), Lawrence Pasternack (2013), or Eddis Miller (2014) embarked on their own versions of such a project. After completing work on Kant’s Critical Religion in 2000 (Palmquist 2000), I initially planned to move directly into full-time work on Kant’s Critical Science, volume three in my planned Kant’s System of Perspectives series. However, I put that plan on hold a few years later, after I realised that Kant’s Critical Religion, despite its length, only scratched the surface of numerous issues relating to Kant’s theory of religion—especially various textual complexities in RGV. Moreover, some critics of Kant’s Critical Religion, even among those who agreed with my overall claim—namely, that Kant was attempting to affirm and even bolster Christianity (albeit in a significantly reformed interpretation)—tended to misconstrue and therefore reject key arguments I had sketched. Clearly, more work needed to be done if the scholarly community was to be convinced that anything like the position I defended there was accurate. (shrink)

El presente trabajo aborda de forma introductoria la exploración y explotación minera en la región de Cuyo y el norte neuquino durante las primeras décadas del siglo XIX. Para esto se analizarán las campañas militares de José Félix Aldao y Pedro Pascual Segura hacia “tierra adentro” y sus vínculos tanto con el contexto político y económico de Mendoza como con la situación de las relaciones interétnicas en la frontera sur de dicha provincia. La hipótesis de la que parte el (...) trabajo es que la crisis económica vivida en Mendoza —la cual estuvo acrecentada por los conflictos político y el deterioro de las relaciones diplomáticas con los principales líderes indígenas— llevó a que se impulsen ambas campañas militares con el fin tanto de eliminar a las parcialidades que no eran aliadas como de explorar y adquirir nuevos recursos económicos, entre ellos nuevos yacimientos mineros situados en territorios indígenas. Metodológicamente, se parte principalmente del análisis de fuentes documentales éditas, de las cuales se obtuvieron los datos con los cuales se llevó adelante el presente estudio. (shrink)

Joaquin Segura. Untitled (fig. 40) . 2007 continent. 1.2 (2011): 117-124. The interview that follows is a dialogue between artist and gallerist with the intent of unearthing the artist’s working strategies for a general public. Joaquin Segura is at once an anomaly in Mexico’s contemporary art scene at the same time as he is one of the most emblematic representatives of a larger shift toward a post-national identity among its youngest generation of artists. If Mexico looks increasingly like (...) a foreclosed home burning to the ground, Segura could likely be the one walking away, charred matchstick between thumb and forefinger and shit-eating grin on his face. His corrosive attacks on institutions, ideologies, and power reflect a deep general distrust of authority, increasingly evident within the work of younger Mexican artists. It is perhaps most directly the result of President Calderon’s deeply unpopular war against the cartels but no doubt equally the product of decades upon decades of rampant corruption and errant policy within Mexico. Brett W Schultz (BWS): A recurring—if not dominant—theme within your current work and investigation explores ideological extremism in reaction to some perceived political and economic disenfranchisement, especially that espoused and practiced by right-wing groups in United States. That's exactly why I thought of you when I was approached to contribute a piece to an issue on the subject of the moraine—taken metaphorically here to signify a certain set of beliefs that have resurfaced within mainstream American culture in the wake of a probably over-exaggerated political sea-change, marked by Obama's election. You're a Mexican artist who now lives and works in Guadalajara, far from the border cities where such concerns would seem more likely to be relevant to a contemporary artist; of course, you're even farther from the culture that birthed this nature of extremism. What interests you so intensely about this movement, if we can call it that? Joaquin Segura (JS): I think there are several seminal points that you touch on in this particular question. There's a very specific set of interests that make me address the socio-political issues I've been dissecting through my practice in the last few years. First of all, I don't really consider myself a 'mexican' artist. As I've made clear in the past, I don't really believe in the notion of 'identity' or the idea of 'nation', which I find totally laughable and heartwarmingly passé. I'm convinced that these are totally outdated models of understanding our differences and similarities, expanding our already immense and irreconcilable cultural abysses instead of bringing them together, thus resulting in their total dispersion among the complex and extremely arbitrary weaving of contemporary social nucleii. Pretty much a frankly bad joke, if I may say so. The fact that I live and work in Mexico is a completely random geographical and temporal factor, which of course affects what I think and what I do, but I've chosen not to be limited by this specific circumstance. In the past, while working abroad, I've taken advantage of this preconception of Mexico—to be more exact, pretty much all of Latin America—as one of the last barbaric bastions of western civilization. Totally amusing, if you ask me about it. I consider my practice to be, among other things, a gonzo strategy of deceit: there are quite a few roles you can adopt in this approach that may actually reveal themselves to be a privileged vantage point. In my experience, the gentle savage is one of the most effective ones to establish my standing position. Thus, I'm a mexican artist if I need it to prove my point. If it's not necessary in a specific circumstance, I'm not. Quite simple, I think. Said in other words, it's just an ace I can play to win a particular match. It has worked so far, at least for me. L: Hey, America… , 2009. R: The Inaugural Address , 2009. I am interested in the nature of power and the rise and fall of totalitarian ideological and political apparatuses nowadays. But I guess, going even further, I'm essentially fascinated by the fissures and contradictions that have made these structures spectacularly crumble to the ground. I do believe extreme ideologies have played a crucial role in the globalization of socio-political crisis. In the end, our world is nothing more than a fading monument to all things gone wrong—the inspiring triumph of failure, in every sense. I see this as an exciting parable. And of course, it is an undeniable fact that the US, through their influence in world economy, international policies and general attitude towards the rest of the planet is the largest structure waiting to collapse. I think we are all secretly awaiting that moment of splendor, even americans. It'll be disastrous and as nasty as it can get, but it will also be liberating and incredibly inspirational. Not just because it’s the US but because it'll prove that absolutely everything is susceptible to fall. And not only that, most importantly, it would confirm that radical change may actually be possible and not just one more of the unfulfilled promises modernity has left us to struggle with on our own. BWS: I want to talk first about two of your works in particular: Hey, America... and The Inaugural Address . I feel like your more recent work has a subtle —or even hidden—sinisterness, but these two works are perfect examples of how brutally confrontational your earlier work has been. When we showed Hey, America... at Mexico City's Zona Maco art fair in 2010, there were at least a couple visitors to our stand who were absolutely ready to punch me in my gringo face for having done so. Certainly the shock value of these works is crucial to their central ideas, but can you tell me more about your intentions and how these works relate to your general oeuvre? JS: So funny. Perhaps we do deserve to be punched in the face. I think that's what I'm sometimes looking for, but I hardly ever get it. I do think of such works as some sort of logical trap, a somewhat perverse ambush waiting for someone to walk into head-on. I think what I tried to do with those two specific works, as well as some other past projects, is just emphasize issues or themes that do disturb or make me uneasy and restless. I consider my essential intention a need to make clear that we do not have to look the other way, ignore or forget. We must address, understand and solve these manifestations of senseless violence and absurdity because if we don't confront them this way, they'll end up consuming us. In other words, I do consider these works as a personal need of coming to terms with the nonsense of the world we all are living in. I don't particularly consider myself to be someone with a clear set of beliefs. Perhaps my only certainty would be that everything is there to be denied, demolished and obliterated—even my supposed unquestionability of that particular 'dogma.' My practice is a reflection of that paradox, and I do think that's how these two pieces relate to a wider body of work. Every democratic system and so-called developed contemporary society is deeply flawed on the inside, and that is because each has swept things under the rug. Of course, there's tolerance, good will and eagerness to make a difference but there's also hatred, pain and fear lingering all around. We must learn to relate to both sides of the spectrum. In a way, I approach the themes behind these particular works in what I think to be a non-biased, somewhat 'neutral' way. I do think there's an encryption process going on in the way I work, some sort of formal refinement of this somewhat outrageous content. A digest of infamy, if we can refer to it that way. It is up to the individual experiencing the work to decide which way these pieces lean. They can easily be seen from both positions and I'm ok with that. If you look closely at these works, there's nothing that establishes an unrelenting position—neither support nor rejection. I don't want my personal political views to directly set an agenda for the spectator as that’s essentially propaganda, which is one of the things I absolutely despise. To sum it up, I strive for the spectator to complete the piece in that sense. The work then becomes a reflection of his or her own contradictions, a playground of the mind. I'm interested in achieving a deadpan and deadlock state in the observer. So, in a way, those visitors threatening to beat the shit out of you unconsciously became that particular issue the work is alluding to. Just blind and senseless reaction to god knows what people feel must be defended, the overwhelming virtue of ambiguity. Beautiful. Perhaps you can also think of my practice as a uber-sophisticated and snobbish version of Punk'd. And you wouldn't be far from what I'm trying to convey. Untitled (Disturbance Scenarios #2) . 2010. BWS: To me, an important transitional marker in the overall trajectory of your work is the series, Disturbance Scenarios , which evokes a similar generalized state of panic, paranoia, and impending doom through its incorporation of sensationalist newspaper headlines, yet also suggests this slyly mysterious meta-narrative via the context in which the newspaper itself is placed. How did you arrive at this series and why did you choose photorealistic painting as the medium for it? JS: I consider this series to be a by-product of the process I follow when making work. I spend an important part of my time just doing research, going through documentation and accumulating visual or historical references for the themes or episodes I'm interested in, in that particular moment. These are, of course, valuable assets that connect among themselves in a mysterious and almost undetectable manner, sometimes a few years between one and the other. I've employed similar production strategies in the past, in ongoing series like Random Moments of Urban Decay , in which I document what I consider to be physical traces of ethnic, religious or ideological violence in the form of text graffiti, invisibly scattered in different cities of the world, mostly in the US. Disturbance Scenarios was started in early 2010, following a particularly intense period of traveling here and there that lasted for most of the year. I've always felt compelled by text, as I find quite intriguing the idea of how words can create equally intense evocations of what I call a mental panorama of uneasiness than those produced by aesthetically-charged imagery; of course, if handled right. I have a close relationship to print media—due both to my academic background and to my attraction to its ubiquity and almost unlimited influence, which in the end, is nothing else but power—so I found myself with a growing archive of newspaper headlines snapshots from cities like Melbourne, Auckland, London, and LA. Going through them, I noticed that they had in common a very specific thematic slant: they were all about some sort of conflict: energy crisis, political unrest, local episodes of domestic violence, you name it. So as you very well put it, I felt they all connected through this feeling of anxiety and anguish and I decided to start thinking of them as a body of work. Basically, I felt an interest in creating what I think of as my personal fragmented prefigurements of the end of civilization. There were few elements on the shots that could give away its actual location, geographically speaking, and I liked that. I find this sensation of vagueness and uncertainty quite alluring. The more subtle, the more perverse. The formal resolution of the series—as photo-realistic painting—is linked to my intention of creating distance between me as the artist and the themes I work with. I rarely execute my own work, and that is more a personal choice as I'm more interested in the ideas I mingle with than in the actual outcome of that process, understood as an "art-object" with certain market value. I did some tests with light-jet prints of those snapshots and I found them devoid of that nightmarish, disturbing indistinctness that I felt was so important for them to be able to project the turmoil I experienced upon encountering them and in conceiving of them as a series. So I thought that photorealistic painting would be an interesting resource to play with, as I hardly had worked with that medium before because of my lenient animosity toward painters and their craft. So they were executed like that and I think it turned out to be just right. Homemade (Napalm #2) . 2010. BWS: Though Disturbance Scenarios remains ongoing, it's an interesting contrast to another series of yours, Homemade, which are these beautifully banal photographs of the ingredients used to make improvised explosives. Whereas Disturbance Scenarios still confronts the viewer aggressively with its visual emphasis on loaded texts, in Homemade , you've dropped the surface-level bravado entirely. They're pieces that require explanation to someone not already versed in the fine art of amateur explosive-making. You weren't known for subtlety in your past work; why this change in direction? JS: I'm personally convinced that these are just two angles of the same conceptual preoccupation. I mentioned before my obsession with the idea of encryption. I'm quite enticed by how these processes of translation can politically and semantically alter and deviate purportedly subversive materials such as the ones these works allude to. I do think subversion is futile. I was really troubled by that thought for some time, but I think now I understand that it's not really that important. What is really significant is to elaborate on these alternate views, to envision and refine possible escape routes. It doesn't really matter if they go nowhere, but that is because nothing really matters. A "mute" artwork is a notion that captivates me. When you look at the works you mention, you know there's something off, but it's not fully clear how and why that is. I rely on that insecurity—on that moment of hesitation. And that can also be achieved through an approach like the one I'm now interested in. Let's just call it a smoke screen, a surrogate ruse to get to the same point: to talk about impotence and defeat in contemporary life. The notion that readily accessible information is actually a weapon is a double-edged fallacy: sure, you can make use of whatever resources you can lay your hands on, but that doesn't set you free because freedom is impossible. Still, that doesn't mean you can't blow up stuff during the process, metaphorically or not. I didn't understand the nature of subtlety before. I used to think that you needed to be loud and manifest anger and unconformity in the most aggressive manner possible. Then I finally realized that you can actually permeate and rarify a battleground—because after all, this is low-intensity war—if you actually aim at silently building up the contradictions and making the symbolic value of ideas and acts clash within themselves. Or perhaps it is that I am just getting old. I guess I used to be an angry kid until recently. Now I think of myself as a disenchanted post-teenager, and of course that reflects in my work and my approach to art-making. Kind of a rite of passage and I laugh at it because, overall, it has been overwhelmingly fun. And that doesn't mean that I'm not ready to stick it in someone or something's face again if I feel like it. BWS: You're now taking the subtlety of the Homemade series even further with your newest series, Definitive Reader For a Botched Revolution , in which you photograph a series of politically-charged books side-on, negating their content entirely—essentially reducing them to purely aesthetic objects in which the subject matter is only revealed in the title of the work. Can you talk about the ideas behind this series? Furthermore, is your recent interest in this idea of the "botched revolution" an indication of a general attitudinal or philosophical shift you've since adopted? JS: This new series of works is the logical outcome of a brief period I went through. Probably the last couple years, in which due to a number of circumstances that don't really have to do with my art-making, I was forced to renegotiate my ideas, my beliefs and practically everything that surrounds me. It was quite distressful and turbulent, but in the end, I think it was also almost epiphanic. I came to terms with myself and now I'm calm and serene. That is, of course, my personal take on it but I mention it because I do think it's important to address this shift you mention. The idea of an artwork as a container for latent revelations enthralls me quite a bit. That's how I see these particular works: art as an incendiary agent. It's up to the artist and the spectator to do whatever they please with it. I think the detachment and almost surgical cleanliness from the Definitive Reader series is also my take at poking fun of the way some art is totally innocuous and uncompromising. These images may be pleasing to the eye, but there's something twisted and rotten within them, well hidden beneath. You'll either see it or not, but without a doubt, it will not cancel its presence. This series is intrinsically linked to Homemade . I'm pretty much horsing around with similar ideas and statements here. And well, yes, I do think any revolution is a botched one. There's nothing too heavy about their own downfall. Decay and breakdown are here and will not go away. Perhaps we must learn to embrace them in one way or another, for our own sake. L: Untitled (T.A.Z.). R: Untitled (United States Marine Guidebook of Essential Subjects) . 2011. BWS: Finally, let's discuss the near future. You've got an upcoming solo show at the Sala de Arte Público Siqueiros [SAPS] in Mexico City this summer. What can we expect from that? What else do you have planned? JS: I'll go and get seafood as soon as I'm done with this interview. It's pretty good here in Guadalajara. That's my top priority at this very moment. About my solo project at SAPS, it's due to open in late July. I'm quite looking forward to it. I'm still closely working with the curator on the general feel for the show but I can say that it'll be more of a revision of past works that have not been shown in Mexico City except for a couple pieces. It definitely won't be a showcase for new projects, although we may include one or two previously unseen works. What you can expect is a rereading of what I've been working on during the past few years. In a way, that's exciting to me because for some reason I don't really care about, I'm not that active in Mexico City even though that's where I lived and work for years. I've hardly shown there after my solo project at Yautepec in February of 2010. It'll be nice to see how it all comes together and I'm more thrilled about it because I totally love the space and I think they're doing an excellent job with their programming and its direction. And in a certain way it feels like going back home. About everything else, I need a period to reflect and fully understand what I've been thinking and working on. I've got a few group shows here and there: New York, San Francisco, and Melbourne are the ones happening soon. I will present my censored project Untitled ( Gringo Loco ) as part of the programming of the Museo de Arte de Zapopan in Guadalajara, two years after being escorted at gunpoint from the installation site by police sent by the extreme right-wing mayor of the city, which I found pretty amusing for an otherwise typical Saturday afternoon. I'm also involved in a couple "curatorial" projects. In my case, "curatorial" means that I help put together stuff I like and I'm interested in. One of them will open in late September of 2011 at Arena Mexico Arte Contemporaneo, and I will work with three of whom I consider to be some of the best artists in a lively and active scene such as the one here in Guadalajara. But most importantly, I've been doing heavy research so there are also a number of projects that I've yet to finalize. That'll be my main focus during the rest of the year, even though I really enjoy procrastination. There'll be time for that later. Or maybe not. We'll see. About Joaquin Segura The action, installation, intervention and photographic work of Joaquin Segura (b. Mexico City, 1980) has been shown in solo and group exhibitions in Mexico, the United States, Europe, and Asia. Some spaces that have featured his work include La Panaderia, Museo de Arte Carrillo Gil, Centro de la Imagen and Ex-Teresa Arte Actual in Mexico City; El Museo del Barrio and apexart, New York, NY; Museo Nacional Centro de Arte Reina Sofia in Madrid, Spain; National Center for Contemporary Art, Moscow, Russia; and Palace Adria in Prague, Czech Republic. In 2008 and 2009, Segura was an artist-in-residence at the International Studio and Curatorial Program, New York, NY and at the 18th Street Arts Center, Santa Monica, CA. He is represented YAUTEPEC in Mexico City and by Arena Mexico Arte Contemporáneo in Guadalajara.

Physical laws are strikingly simple, although there is no a priori reason they must be so. I propose that nomic realists of all types (Humeans and non-Humeans) should accept that simplicity is a fundamental epistemic guide for discovering and evaluating candidate physical laws. This principle of simplicity clarifies and addresses several problems of nomic realism and simplicity. A consequence is that the oft-cited epistemic advantage of Humeanism over non-Humeanism disappears, undercutting an influential epistemological argument for Humeanism. Moreover, simplicity is shown (...) to be more tightly connected to lawhood than to mere truth. (shrink)

In a quantum universe with a strong arrow of time, we postulate a low-entropy boundary condition to account for the temporal asymmetry. In this paper, I show that the Past Hypothesis also contains enough information to simplify the quantum ontology and define a unique initial condition in such a world. First, I introduce Density Matrix Realism, the thesis that the quantum universe is described by a fundamental density matrix that represents something objective. This stands in sharp contrast to Wave Function (...) Realism, the thesis that the quantum universe is described by a wave function that represents something objective. Second, I suggest that the Past Hypothesis is sufficient to determine a unique and simple density matrix. This is achieved by what I call the Initial Projection Hypothesis: the initial density matrix of the universe is the normalized projection onto the special low-dimensional Hilbert space. Third, because the initial quantum state is unique and simple, we have a strong case for the \emph{Nomological Thesis}: the initial quantum state of the universe is on a par with laws of nature. This new package of ideas has several interesting implications, including on the harmony between statistical mechanics and quantum mechanics, the dynamic unity of the universe and the subsystems, and the alleged conflict between Humean supervenience and quantum entanglement. (shrink)

If there are fundamental laws of nature, can they fail to be exact? In this paper, I consider the possibility that some fundamental laws are vague. I call this phenomenon 'fundamental nomic vagueness.' I characterize fundamental nomic vagueness as the existence of borderline lawful worlds and the presence of several other accompanying features. Under certain assumptions, such vagueness prevents the fundamental physical theory from being completely expressible in the mathematical language. Moreover, I suggest that such vagueness can be regarded as (...) 'vagueness in the world.' For a case study, we turn to the Past Hypothesis, a postulate that (partially) explains the direction of time in our world. We have reasons to take it seriously as a candidate fundamental law of nature. Yet it is vague: it admits borderline (nomologically) possible worlds. An exact version would lead to an untraceable arbitrariness absent in any other fundamental laws. However, the dilemma between fundamental nomic vagueness and untraceable arbitrariness is dissolved in a new quantum theory of time's arrow. (shrink)

A century after the discovery of quantum mechanics, the meaning of quantum mechanics still remains elusive. This is largely due to the puzzling nature of the wave function, the central object in quantum mechanics. If we are realists about quantum mechanics, how should we understand the wave function? What does it represent? What is its physical meaning? Answering these questions would improve our understanding of what it means to be a realist about quantum mechanics. In this survey article, I review (...) and compare several realist interpretations of the wave function. They fall into three categories: ontological interpretations, nomological interpretations, and the sui generis interpretation. For simplicity, I will focus on non-relativistic quantum mechanics. (shrink)

The mathematical structure of realist quantum theories has given rise to a debate about how our ordinary 3-dimensional space is related to the 3N-dimensional configuration space on which the wave function is defined. Which of the two spaces is our (more) fundamental physical space? I review the debate between 3N-Fundamentalists and 3D-Fundamentalists and evaluate it based on three criteria. I argue that when we consider which view leads to a deeper understanding of the physical world, especially given the deeper topological (...) explanation from the unordered configurations to the Symmetrization Postulate, we have strong reasons in favor of 3D-Fundamentalism. I conclude that our evidence favors the view that our fundamental physical space in a quantum world is 3-dimensional rather than 3N-dimensional. I outline lines of future research where the evidential balance can be restored or reversed. Finally, I draw lessons from this case study to the debate about theoretical equivalence. (shrink)

Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. I propose a unified 'Humean' solution to the two problems. Humeanism allows us to incorporate the Past Hypothesis and the Statistical Postulate into the best system, which we then use to simplify the quantum state of the universe. This enables us to confer the nomological status to the quantum state in (...) a way that adds no significant complexity to the best system and solves the ''supervenient-kind problem'' facing the original version of the Past Hypothesis. We call the resultant theory the Humean unification. It provides a unified explanation of time asymmetry and quantum entanglement. On this theory, what gives rise to time's arrow is also responsible for quantum phenomena. The new theory has a separable mosaic, a best system that is simple and non-vague, less tension between quantum mechanics and special relativity, and a higher degree of theoretical and dynamical unity. The Humean unification leads to new insights that can be useful to Humeans and non-Humeans alike. (shrink)

Realism about quantum theory naturally leads to realism about the quantum state of the universe. It leaves open whether it is a pure state represented by a wave function, or an impure one represented by a density matrix. I characterize and elaborate on Density Matrix Realism, the thesis that the universal quantum state is objective but can be impure. To clarify the thesis, I compare it with Wave Function Realism, explain the conditions under which they are empirically equivalent, consider two (...) generalizations of Density Matrix Realism, and answer some frequently asked questions. I end by highlighting an implication for scientific realism. (shrink)

Philosophers working in the nascent field of ‘experimental philosophy’ have begun using methods borrowed from psychology to collect data about folk intuitions concerning debates ranging from action theory to ethics to epistemology. In this paper we present the results of our attempts to apply this approach to the free will debate, in which philosophers on opposing sides claim that their view best accounts for and accords with folk intuitions. After discussing the motivation for such research, we describe our methodology of (...) surveying people’s prephilosophical judgments about the freedom and responsibility of agents in deterministic scenarios. In two studies, we found that a majority of participants judged that such agents act of their own free will and are morally responsible for their actions. We then discuss the philosophical implications of our results as well as various difficulties inherent in such research. (shrink)

Although CEO commitment is recognized as being crucial to organizational diversity efforts, we know little about how CEOs signal their priorities and mobilize key organizational actors to implement diversity management. We tested an integrative model in which CEO beliefs about diversity were theorized to predict the implementation of organizational diversity practices through two consecutive mediating steps—via greater CEO engagement in pro-diversity behavior, and in turn, higher perceived CEO commitment by their HR manager. In this model, we also proposed a moderating (...) effect such that when CEOs have less positive beliefs about diversity, CEOs espousing higher moral values will display greater pro-diversity behavior. Results supported the proposed model. Taken together, our findings indicate that a CEO’s words and actions alone are not sufficient for the implementation of diversity management practices. HR managers must view their CEOs as being committed to workplace diversity in order for diversity management practices to be implemented. (shrink)

Recent trends towards an e-Science offer us the opportunity to think about the specific epistemological changes created by computational empowerment in scientific practices. In fact, we can say that a computational epistemology exists that requires our attention. By ‘computational epistemology’ I mean the computational processes implied or required to achieve human knowledge. In that category we can include AI, supercomputers, expert systems, distributed computation, imaging technologies, virtual instruments, middleware, robotics, grids or databases. Although several authors talk about the extended mind (...) and computational extensions of the human body, most of these proposals don’t analyze the deep epistemological implications of computer empowerment in scientific practices. At the same time, we must identify the principal concept for e-Science: Information. Why should we think about a new epistemology for e-Science? Because several processes exist around scientific information that require a good epistemological model to be understood. (shrink)

The Great Divide in metaphysical debates about laws of nature is between Humeans, who think that laws merely describe the distribution of matter, and non-Humeans, who think that laws govern it. The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental direction of (...) time in the universe. In this paper, we propose a minimal primitivism about laws of nature (MinP) according to which there is no such requirement. On our view, laws govern by constraining the physical possibilities. Our view captures the essence of the governing view without taking on extraneous commitments about the direction of time or dynamic production. Moreover, as a version of primitivism, our view requires no reduction / analysis of laws in terms of universals, powers, or dispositions. Our view accommodates several potential candidates for fundamental laws, including the principle of least action, the Past Hypothesis, the Einstein equation of general relativity, and even controversial examples found in the Wheeler-Feynman theory of electrodynamics and retrocausal theories of quantum mechanics. By understanding governing as constraining, non-Humeans who accept MinP have the same freedom to contemplate a wide variety of candidate fundamental laws as Humeans do. (shrink)

In a quantum universe with a strong arrow of time, it is standard to postulate that the initial wave function started in a particular macrostate---the special low-entropy macrostate selected by the Past Hypothesis. Moreover, there is an additional postulate about statistical mechanical probabilities according to which the initial wave function is a ''typical'' choice in the macrostate. Together, they support a probabilistic version of the Second Law of Thermodynamics: typical initial wave functions will increase in entropy. Hence, there are two (...) sources of randomness in such a universe: the quantum-mechanical probabilities of the Born rule and the statistical mechanical probabilities of the Statistical Postulate. I propose a new way to understand time's arrow in a quantum universe. It is based on what I call the Thermodynamic Theories of Quantum Mechanics. According to this perspective, there is a natural choice for the initial quantum state of the universe, which is given by not a wave function but by a density matrix. The density matrix plays a microscopic role: it appears in the fundamental dynamical equations of those theories. The density matrix also plays a macroscopic / thermodynamic role: it is exactly the projection operator onto the Past Hypothesis subspace. Thus, given an initial subspace, we obtain a unique choice of the initial density matrix. I call this property "the conditional uniqueness" of the initial quantum state. The conditional uniqueness provides a new and general strategy to eliminate statistical mechanical probabilities in the fundamental physical theories, by which we can reduce the two sources of randomness to only the quantum mechanical one. I also explore the idea of an absolutely unique initial quantum state, in a way that might realize Penrose's idea of a strongly deterministic universe. (shrink)

If the Past Hypothesis underlies the arrows of time, what is the status of the Past Hypothesis? In this paper, I examine the role of the Past Hypothesis in the Boltzmannian account and defend the view that the Past Hypothesis is a candidate fundamental law of nature. Such a view is known to be compatible with Humeanism about laws, but as I argue it is also supported by a minimal non-Humean "governing'' view. Some worries arise from the non-dynamical and time-dependent (...) character of the Past Hypothesis as a boundary condition, the intrinsic vagueness in its specification, and the nature of the initial probability distribution. I show that these worries do not have much force, and in any case they become less relevant in a new quantum framework for analyzing time's arrows---the Wentaculus. Hence, the view that the Past Hypothesis is a candidate fundamental law should be more widely accepted than it is now. (shrink)

A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), "it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.” Such an extraordinary feature may appear unattainable in a world like ours. In this paper, I show that it can be achieved in a simple way and (...) discuss its implications for metaphysics and philosophy of science, including natural properties, free will, explanation, and modality. First, I propose a precise definition of strong determinism. Next, I discuss its philosophical ramifications and a toy example. Finally, I provide a realistic example of a strongly deterministic (and simple) physical theory---the Everettian Wentaculus. A surprising consequence is that whether or not our world is strongly deterministic may be empirically underdetermined. (shrink)

Although expected utility theory has proven a fruitful and elegant theory in the finite realm, attempts to generalize it to infinite values have resulted in many paradoxes. In this paper, we argue that the use of John Conway's surreal numbers shall provide a firm mathematical foundation for transfinite decision theory. To that end, we prove a surreal representation theorem and show that our surreal decision theory respects dominance reasoning even in the case of infinite values. We then bring our theory (...) to bear on one of the more venerable decision problems in the literature: Pascal's Wager. Analyzing the wager showcases our theory's virtues and advantages. To that end, we analyze two objections against the wager: Mixed Strategies and Many Gods. After formulating the two objections in the framework of surreal utilities and probabilities, our theory correctly predicts that (1) the pure Pascalian strategy beats all mixed strategies, and (2) what one should do in a Pascalian decision problem depends on what one's credence function is like. Our analysis therefore suggests that although Pascal's Wager is mathematically coherent, it does not deliver what it purports to, a rationally compelling argument that people should lead a religious life regardless of how confident they are in theism and its alternatives.

The wave function in quantum mechanics presents an interesting challenge to our understanding of the physical world. In this paper, I show that the wave function can be understood as four intrinsic relations on physical space. My account has three desirable features that the standard account lacks: it does not refer to any abstract mathematical objects, it is free from the usual arbitrary conventions, and it explains why the wave function has its gauge degrees of freedom, something that are usually (...) put into the theory by hand. Hence, this account has implications for debates in philosophy of mathematics and philosophy of science. First, by removing references to mathematical objects, it provides a framework for nominalizing quantum mechanics. Second, by excising superfluous structure such as overall phase, it reveals the intrinsic structure postulated by quantum mechanics. Moreover, it also removes a major obstacle to ``wave function realism.''. (shrink)

In this paper, I characterize and elaborate on the “Wentaculus” theory, a new approach to time’s arrow in a quantum universe that offers a unified solution to the problems of what gives rise to the arrow of time and what the ontology of quantum mechanics is.

Despite its apparent complexity, our world seems to be governed by simple laws of physics. This volume provides a philosophical introduction to such laws. I explain how they are connected to some of the central issues in philosophy, such as ontology, possibility, explanation, induction, counterfactuals, time, determinism, and fundamentality. I suggest that laws are fundamental facts that govern the world by constraining its physical possibilities. I examine three hallmarks of laws-simplicity, exactness, and objectivity-and discuss whether and how they may be (...) associated with laws of physics. (shrink)
