Profinite groups are Galois groups. The effective study of infinite Galois groups was initiated by Metakides and Nerode [8] and further developed by LaRoche [5]. In this paper we study profinite groups without considering Galois extensions of fields. The Artin method of representing a finite group as a Galois group has been generalized by Waterhouse [14] to profinite groups. Thus, there is no loss of relevance in our approach.The fundamental notions of a co-r.e. profinite group, recursively profinite group, and the (...) degree of a co-r.e. profinite group are defined in §1. In this section we prove that every co-r.e. profinite group can be effectively represented as an inverse limit of finite groups. The degree invariant is shown to behave very well with respect to open subgroups and quotients. The work done in this section is basic to the rest of the paper.The commutator subgroup, the Frattini subgroup, thep-Sylow subgroups, and the center of a profinite group are essential in the study of profinite groups. It is only natural to ask if these subgroups are effective. The following question exemplifies our approach to this problem: Is the center a co-r.e. profinite group? Theorem 2 provides a general method for answering this type of question negatively. Examples 3,4 and 5 are all applications of this theorem. (shrink)

This paper continues joint work of the authors with P. Clote, R. Soare and S. Wainer (Annals of Pure and Applied Logic, vol. 31 (1986), pp. 145--163). An element x of the Cantor space 2 ω is said have rank α in the closed set P if x is in $D^\alpha(P)\backslash D^{\alpha + 1}(P)$ , where D α is the iterated Cantor-Bendixson derivative. The rank of x is defined to be the least α such that x has rank α in (...) some Π 0 1 set. The main result of the five-author paper is that for any recursive ordinal λ + n (where λ is a limit and n is finite), there is a point with rank λ + n which is Turing equivalent to O (λ + 2n) . All ranked points constructed in that paper are Π 0 2 singletons. We now construct a ranked point which is not a Π 0 2 singleton. In the previous paper the points of high rank were also of high hyperarithmetic degree. We now construct ▵ 0 2 points with arbitrarily high rank. We also show that every nonrecursive RE point is Turing equivalent to an RE point of rank one and that every nonrecursive ▵ 0 2 point is Turing equivalent to a hyperimmune point of rank one. We relate Clote's notion of the height of a Π 0 1 singleton in the Baire space with the notion of rank. Finally, we show that every hyperimmune point x is Turing equivalent to a point which is not ranked. (shrink)

In recent years there has been an increased awareness with regards to ethics in business. More specifically, the abundance of well-publicized examples of cheating, greed, and hypocrisy has created some alarm about the general state of personal ethics. Recent examples include the Oliver North, Ivan Boesky, and Jimmy Swaggart cases. The tax practitioner probably has little direct concern for matters of misconduct and ethical improprieties as mentioned above. Adherence to a code of conduct appears to circumvent the ethical conflict typically (...) found in the business environment. The tax practitioner's ultimate goal is tax minimization for clients. This goal has the blessings of the courts and the writers of tax law.The present day dynamic global economic system includes organizations which have extensive international activity. In an effort to enhance the performance of these organizations, there is typically decentralization of operations. When decentralization exists it is necessary to evaluate the decentralized units. Profit centers are commonly used for this purpose. With profit centers comes the need for transfer pricing between profit centers. The transfer price should be determined in some objective fashion. However, tax minimization often is the driving force in the transfer price decision. (shrink)

The authors attempt to prove that single energy arrays cannot specify reality. We offer contrary evidence that motion structures the acoustic array to specify fundamental attributes of the source. Against direct detection in general, we cite evidence that humans weight acoustic inputs differentially when making perceptual judgments of auditory motion.

Extending the growing literature on the role of grit in different life domains, this research explores the relationship between grit and involvement in entrepreneurship. The research highlights the role of personal income and satisfaction with one’s current financial situation as moderators of the relationship between grit and entrepreneurial behavior. Using a large representative sample of Spanish young adults and controlling for a number of potential confounding variables, we find that grit is modestly negatively related to the probability of involvement in (...) entrepreneurship. As predicted, however, this relationship is qualified by both income and satisfaction with current financial situation, though in opposite directions and more weakly for satisfaction with financial status. Gritty individuals with higher levels of income are more prone to become entrepreneurs than gritty individuals with lower levels of income. Gritty individuals with lower levels of satisfaction with their financial situation are more likely to set up a business or become self-employed. (shrink)

Both Ancient Chinese and Greek philosophers provide accounts of the life lived well: a Confucian junzi, a Daoist sage and a Greek phronimos. Cultivation in Early China and Ancient Greece engages in comparative, cross-tradition scholarship and investigates the processes associated with cultivating or nurturing the self in order to live such lives. -/- By focusing on the processes rather than the aims of cultivating a good life, an international team of scholars investigate how a person develops and practices a way (...) of life. They look at what is involved in developing practical wisdom, exercising reason, cultivating equanimity and fostering reliability. Using the thought of those thinkers central to both traditions, including Plato, Confucius, Han Fei and Marcus Aurelius, they examine themes of harmony, balance and beauty, and highlight the different concerns of scepticism across both traditions. They also discuss the action of doing as an indispensable method of learning. As a result, Cultivation in Early China and Ancient Greece is a valuable collection opening up new lines of inquiry in ethics and demonstrating the importance of drawing on philosophical ideas from across cultural traditions.

This paper follows the question of violence as a guide to exploring the link between the metaphysical, social, and political in Adorno’s thought. More specifically, I argue that violence, in the form of the exclusion, domination, and fungibility of life, marks the shared space of the metaphysical, material, and ethical for Adorno. Hence, this project contests the longstanding Habermas-inspired notion that there is something unclear in the way in which Adorno’s metaphysical and methodological critiques connect to his social and political (...) concerns—most specifically, his desire to address real suffering. In addition, this paper contributes to the growing interest in Adorno’s Marxism, showing that it is through his commitments to Marx that Adorno sees the real, material importance of his critique of metaphysics and ontology, as well as the possibility for resisting the forces of social domination.Cet article suit la question de la violence comme une guide pour explorer le lien entre la métaphysique, le social et le politique dans la pensée d’Adorno. Plus particulièrement, je soutiens que la violence, sous la forme de l’exclusion, la domination et la fongibilité de la vie, marque l’espace partagé de la métaphysique, du matériel et de l’éthique chez Adorno. Dès lors, ce projet remet en cause la notion de longue date inspirée par Habermas selon laquelle il y aurait quelque manque de clarté dans la manière dont les critiques métaphysiques et méthodologiques d’Adorno se relient avec ses soucis sociaux et politiques—plus spécifiquement son désir de s’occuper de la souffrance réelle. Par ailleurs, cette étude contribue à l’intérêt en plein essor au marxisme d’Adorno, montrant que c’est dans ses engagements avec Marx qu’Adorno voit l’importance réelle et matérielle de sa critique de la métaphysique et de l’ontologie, ainsi que la possibilité de résister aux forces de la domination sociale.

The Laws is the longest and, according to tra-dition, the last of Plato’s dialogues. It was left ‘in the wax’ at the time of Plato’s death and brought into publication by Philip of Opus (D. L. 3.37). Whether Philip had a hand in editing the work or whether he merely tran-scribed it is uncertain (for one recent account, see Nails and Thesleff 2003). The most recent analyses of its style indicate significant affini-ties with the Sophist, Politicus and Philebus, though there (...) are stark differences in places. These, however, might be explained in vari-ous ways, and there has never been any ques-tion that the Lg. substantially contains the thought of Plato. If we set special problems of composition aside, including admittedly serious questions about the overall coher-ence of the dialogue, then the chief difficul-ties remaining for an interpreter of the Lg. include (a) its dramatic date and structure, (b) its relation to other political dialogues of Plato, especially the Republic and the Plt. and (c) the extensive discussion of cosmology and theology in L. bk 10.

According to the canon of Thrasyllus (see D. L. 3.59), Plato’s Laches is about cour-age and employs, to borrow a term from Theaetetus 149a–51d, an ‘obstetric’ method, in which the ideas of Socrates’ interlocu-tors are delivered into the light of day and examined. These Thrasyllan labels correctly identify the simple theme and tactic of the La., but as with all of the Socratic dialogues, apparent simplicity disguises enormous sub-tlety of structure and composition. One thing that seems hidden from most readers (...) is the special relation between theme and tactic, namely that the practise of Socratic dialogue requires and exhibits courage in examining what one really thinks.

© 2015, Springer-Verlag Berlin Heidelberg.Genetic studies have identified single nucleotide polymorphisms associated with the risk of prostate cancer. It remains unclear whether such genetic variants are associated with disease aggressiveness. The NCI-SPORE Genetics Working Group retrospectively collected clinicopathologic information and genotype data for 36 SNPs which at the time had been validated to be associated with PC risk from 25,674 cases with PC. Cases were grouped according to race, Gleason score and aggressiveness. Statistical analyses were used to compare the frequency (...) of the SNPs between different disease cohorts. After adjusting for multiple testing, only PC-risk SNP rs2735839 was significantly and inversely associated with aggressive and high-grade disease in European men. Similar associations with aggressive and high-grade disease were documented in African-American subjects. The G allele of rs2735839 was associated with disease aggressiveness even at low PSA levels in both European and African-American men. Our results provide further support that a PC-risk SNP rs2735839 near the KLK3 gene on chromosome 19q13 may be associated with aggressive and high-grade PC. Future prospectively designed, case-case GWAS are needed to identify additional SNPs associated with PC aggressiveness. (shrink)

Book review of Jay Garfield's Engaging Buddhism: Why It Matters to Philosophy.

A strength of Jablonka & Lamb's (J&L's) book lies in its accessible as well as thorough treatment of genetic and epigenetic inheritance. The authors also provide a stimulating framework integrating evolutionary research across disciplines. A weakness is its unsystematic treatment of the interaction between behavioral and symbolic inheritance, particularly in their discussion of language.

In Buddhism, Meditation and Free Will: A Theory of Mental Freedom , Rick Repetti explains how the dynamics of Buddhist meditation can result in a kind of metacognition and metavolitional control that exceeds what is required for free will and defeats the most powerful forms of free will skepticism. This article argues that although the Buddhist path requires and enhances the kind of mental and volitional control Repetti describes, the central dynamic of the path and meditation is better understood (...) as a process of habituation. This not only involves the dis‐identification from mental and emotional content that Repetti discusses—and is commonly emphasized in modern presentations of mindfulness or insight (vipassanā ) meditation—but also a transformation of the heart that is effected through the complementary psychological and somatic qualities associated with calm abiding (samatha ) and concentration (samādhi ) and emphasized in the Pali Nikāyas and commentaries.

In lieu of an abstract, here is a brief excerpt of the content:Reading the Mind:From George Eliot's Fiction to James Sully's PsychologyVanessa L. RyanWhat is the function and value of fiction? Debates over these questions involve considerations that range from aesthetics to ethics, from the intrinsic values of the genre to its moral effects. Recently, largely under the influence of the cognitive sciences, the question has taken on a new cast: might science give us a new answer to these long-standing (...) issues? Studies such as Lisa Zunshine's Why We Read Fiction (2006), John Carey's What Good Are the Arts? (2005), and Alan Palmer's Fictional Minds (2004) are part of a growing area of interdisciplinary work on the relationship between art and consciousness.1 This body of work asks not just how our theories of consciousness inform our understanding of the process and function of [End Page 615] reading fiction, but also whether fiction itself might provide a key to new theories about the nature of consciousness.The nineteenth-century novel is often considered the high point in the literary representation of mind. Indeed, the terms "psychology" and "novel" are explicitly yoked in the nineteenth-century with the simultaneous emergence of both as discrete forms of intellectual and artistic activity. Not surprisingly, George Eliot has come to be identified with the term "psychological novel": in fact, Nicholas Dames argues that she was the first to couple the words psychology and novel in this way in an 1855 review where she contrasted Charles Kingsley's historical romance Westward Ho! with "those 'psychological' novels."2 While George Eliot initially used the phrase in what Dames calls "mock disdain," by the end of the nineteenth century the term "psychological novel" had gained currency as a straightforward description of a type of Victorian novel: Wilbur Cross, in his summary The Development of the English Novel, for example, describes the form as "stressing an inner sequence of thought and feeling, which is brought into harmony with an ethical formula and accounted for in an analysis of motive." Along with Elizabeth Gaskell and George Meredith, Cross also cites George Eliot as one of his central examples of the "psychological novel."3It seems natural, then, when a critic asks, "what is the special distinguishing function of the modern art of fiction?" to turn for an answer to George Eliot's novels and their close connections with psychological science. It is perhaps surprising that this still-current question was posed by the nineteenth-century psychologist James Sully (1842–1923) in an 1881 article in the journal Mind on "George Eliot's Art."4 His essay offers us a Victorian contribution to questions about the relationship of literature and psychology that are being addressed today by critics such as Sally Shuttle-worth, Athena Vrettos, Kay Young, Nicholas Dames, or Rick Rylance, especially [End Page 616] with respect to George Eliot. James Sully's essay not only provides valuable insight into how the Victorians themselves understood the role of psychology in the novel, but also helps to place contemporary debates about fiction and consciousness into sharper relief.In the wake of important studies, such as Rylance's Victorian Psychology and British Culture (2000), that have brought renewed attention to nineteenth-century British psychology, recent scholarship has shown the central role of Victorian debates about the mind in shaping the fiction of the period.5 Nineteenth-century mental science provided material and inspiration for works of literature, with imaginative writers eager to exploit and develop the narrative and thematic potential of contemporary psychological discourse and probe the problems it raised. Novelists such as Wilkie Collins, George Eliot, and Henry James turned to some of the most current work in the science of the mind, which they saw as the most sophisticated and credible approach to psychological realism available. These and other novelists rapidly absorbed the central terms of the new science as it considered problems of consciousness, identity, and memory, and brought them to life by dramatizing and questioning them in their fiction. James Sully's interest in George Eliot reflects this fruitful mid- to late-nineteenth-century cross-pollination between philosophers, scientists, and novelists who were interested in the nature of consciousness, psychology...

Examines how the educations of America's first four presidents, and in particular their scholarly devotion to ancient Greek and Roman classics, informed the beliefs and ideals that shaped the nation's constitution and government.

This brief commentary has three goals. The first is to argue that ‘‘framework debate’’ in cognitive science is unresolvable. The idea that one theory or framework can singly account for the vast complexity and variety of cognitive processes seems unlikely if not impossible. The second goal is a consequence of this: We should consider how the various theories on offer work together in diverse contexts of investigation. A final goal is to supply a brief review for readers who are compelled (...) by these points to explore existing literature on the topic. Despite this literature, pluralism has garnered very little attention from broader cognitive science. We end by briefly considering what it might mean for theoretical cognitive science. (shrink)

We explored the influence of negation on cognitive dynamics, measured using mouse‐movement trajectories, to test the classic notion that negation acts as an operator on linguistic processing. In three experiments, participants verified the truth or falsity of simple statements, and we tracked the computer‐mouse trajectories of their responses. Sentences expressing these facts sometimes contained a negation. Such negated statements could be true (e.g., “elephants are not small”) or false (e.g., “elephants are not large”). In the first experiment, as predicted by (...) the classic notion of negation, we found that negation caused more discreteness in the mouse trajectory of a response. The second experiment induced a simple context for these statements, yet negation still increased discreteness in trajectories. A third experiment enhanced the pragmatic context of sentences, and the discreteness was substantially diminished, with one primary measure no longer significantly showing increased discreteness at all. Traditional linguistic theories predict rapid shifts in cognitive dynamics occur due to the nature of negation: It is an operator that reverses the truth or falsity of an interpretation. We argue that these results support both propositional and contextual accounts of negation present in the literature, suggesting that contextual factors are crucial for determining the kind of cognitive dynamics displayed. We conclude by drawing broader lessons about theories of cognition from the case of negation. (shrink)

Through theoretical discussion, literature review, and a computational model, this paper poses a challenge to the notion that perspective-taking involves a fixed architecture in which particular processes have priority. For example, considerable work has shown that egocentric perspectives can arise more quickly, with other perspectives (such as of task partners) emerging only secondarily. This theoretical dichotomy is challenged here, and we propose a general view of perspective-taking as an emergent phenomenon governed by the interplay among several cognitive mechanisms. We first (...) describe the pervasive relevance of perspective-taking to cognitive science. A dynamical systems model is then introduced which explicitly formulates the timescale interaction proposed. Implications are discussed, with ideas for future empirical research. (shrink)

Using the Godel incompleteness result for leverage, Roger Penrose has argued that the mechanism for consciousness involves quantum gravitational phenomena, acting through microtubules in neurons. We show that this hypothesis is implausible. First the Godel result does not imply that human thought is in fact non-algorithmic. Second, whether or not non-algorithmic quantum gravitational phenomena actually exist, and if they did how that could conceivably implicate microtubules, and if microtubules were involved, how that could conceivably implicate consciousness, is entirely speculative. Third, (...) cytoplasmic ions such as calcium and sodium are almost certainly present in the microtubule pore, barring the quantum-mechanical effects Penrose envisages. Finally, physiological evidence indicates that consciousness does not directly depend on microtubule properties in any case, rendering doubtful any theory according to which consciousness is generated in the microtubules.

Groundhog Day (Harold Ramis, 1993) and Only Lovers Left Alive (Jim Jarmusch, 2013) are fantasy films that use the device of practical immortality in order to raise important philosophical questions about what constitutes a good life and to explore the nature of romantic love. Groundhog Day provides fairly conventional answers about how to live a good life by focusing on issues of spiritual redemption, selflessness, and developing one’s human potential. In contrast, Lovers provides a dark portrayal of a civilization on (...) the brink of extinction but offers a glimmer of hope for the future. The lifestyle and values of married vampires Adam and Eve represent an alternative vision of the core values needed to sustain a better world: greater reliance on human imagination, maintaining a sense of wonder and curiosity about the world, creating and appreciating works of art and living in harmony with the natural world. Both films also offer a perspective on the importance of romantic love in living a good life. Although these perspectives often diverge from one another, they do overlap in some interesting ways. The style of film criticism used in this paper is inspired by the film philosophy of Stanley Cavell. (shrink)

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...) parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language. Key Words: efference copies; emulation theory of representation; forward models; Kalman filters; motor control; motor imagery; perception; visual imagery. (shrink)
