BackgroundReflexive pitch perturbation experiments are commonly used to investigate the neural mechanisms underlying vocal motor control. In these experiments, the fundamental frequency–the acoustic correlate of pitch–of a speech signal is shifted unexpectedly and played back to the speaker via headphones in near real-time. In response to the shift, speakers increase or decrease their fundamental frequency in the direction opposing the shift so that their perceived pitch is closer to what they intended. The goal of the current work is to develop (...) a quantitative model of responses to reflexive perturbations that can be interpreted in terms of the physiological mechanisms underlying the response and that captures both group-mean data and individual subject responses.MethodsA model framework was established that allowed the specification of several models based on Proportional-Integral-Derivative and State-Space/Directions Into Velocities of Articulators (DIVA) model classes. The performance of 19 models was compared in fitting experimental data from two published studies. The models were evaluated in terms of their ability to capture both population-level responses and individual differences in sensorimotor control processes.ResultsA three-parameter DIVA model performed best when fitting group-mean data from both studies; this model is equivalent to a single-rate state-space model and a first-order low pass filter model. The same model also provided stable estimates of parameters across samples from individual subject data and performed among the best models to differentiate between subjects. The three parameters correspond to gains in the auditory feedback controller’s response to a perceived error, the delay of this response, and the gain of the somatosensory feedback controller’s “resistance” to this correction. Excellent fits were also obtained from a four-parameter model with an additional auditory velocity error term; this model was better able to capture multi-component reflexive responses seen in some individual subjects.ConclusionOur results demonstrate the stereotyped nature of an individual’s responses to pitch perturbations. Further, we identified a model that captures population responses to pitch perturbations and characterizes individual differences in a stable manner with parameters that relate to underlying motor control capabilities. Future work will evaluate the model in characterizing responses from individuals with communication disorders. (shrink)

It is argued, on the basis of ideas derived from Wittgenstein's Tractatus and Husserl's Logical Investigations, that the formal comprehends more than the logical. More specifically: that there exist certain formal-ontological constants (part, whole, overlapping, etc.) which do not fall within the province of logic. A two-dimensional directly depicting language is developed for the representation of the constants of formal ontology, and means are provided for the extension of this language to enable the representation of certain materially necessary relations. The (...) paper concludes with a discussion of the relationship between formal logic, formal ontology, and mathematics. (shrink)

The relevance of Marx’s theory of value and his ‘law of the tendency of the rate of profit to fall’ to the analysis of the financial crisis of 2007–8 and the ensuing global slump is affirmed. The hypertrophic growth of unproductive constant capital, including the wages of ‘socially necessary’ unproductive labour and tax revenues, is identified as an important manifestation of an historical-structural crisis of capitalism, alongside the increasing weight of fictitious capital and the proliferation of fictitious profits in the (...) lead-up to the financial crisis. These phenomena have obscured the deepest roots of the global slump in the long-term profitability problems of productive capital – that is, in a crisis of surplus-value production. With these considerations taken into account, a better empirical assessment of trends in the composition of capital becomes possible, and with it a more accurate understanding of the impact of the ongoing displacement of living labour from production on the average rate of profit and the future of US and global capitalism.

The publication last year in New Left Review of Robert Brenner's book-length essay ‘Uneven Development and the Long Downturn: The Advanced Capitalist Economies from Boom to Stagnation, 1950-1998’ has already provoked more discussion and controversy on the socialist Left than any other political-economic analysis in recent memory. Predictably, it has also elicited a number of highly critical response from proponents of Marx's theories of labour value and economic crisis. Amongst other things, Brenner has been charged with a one-sided preoccupation with (...) capital-to-capital relations at the expense of the capital-wage labour relation, with misinterpreting and dismissing Marx's law of the falling tendency of the rate of profit, and with ignoring Marx’s value categories entirely.

In ‘Rethinking Nature,’ Shaun Gallagher makes the case for a non-reductive, naturalized phenomenology. In doing so, he seeks to close the metaphysical gap between world and mind by pursuing a ‘world > mind’ strategy, conforming the natural world to the world of reason and experience. Here I assess the merits of this approach by comparison with the alternative ‘mind > world’ strategy, whereby the the world of reason and experience is conformed to the natural world. This latter approach is exemplified (...) by the method of ‘triangulating’ the mind through the integration of experiential, psychological, and neurophysiological evidence. While sympathetic to Gallagher’s ambition and aspects of his approach, I raise some doubts about the anti- or non-representational model of mind that he believes his revisionist metaphysics of nature supports. Arguably, representational assumptions are built into the concepts of perception, the senses, and the mind itself. Thus, even if the metaphysical gap between mind and world can be closed, the epistemic gap between an agent and its environment must still be bridged by the engine of representation that is the extended and embodied mind.

Discussion surrounding Marx's distinction between productive and unproductive labor too often fails to distinguish between the various forms that unproductive labor may assume and is too hasty to subsume the income of workers "unproductively" employed by capital as a non-profit component of social surplus-value. Against this, it may be argued that many forms of unproductive labor are socially necessary to the social capital and are therefore properly viewed as systemic overhead costs. As such, they should be treated, in value-theoretical terms, (...) as elements of the constant capital flow. The implications of this approach are explored for crisis theory and the evolution of the class structure with particular reference to the Canadian experience in this century. (shrink)

The idea that human history evinces a pattern of development rooted in the propensity of human beings toward technical forms of rationality is fundamental to Marx's materialist conception of history. Yet the "dialectic of forces and relations of production" as traditionally conceived in historical-materialist discourse has found only weak expressions in social formations dominated by precapitalist modes of production. The hypothesis is advanced that the role of simple commodity production and exchange in such formations may be decisive to the emergence (...) of cognitive faculties capable of giving a systematic impulse to the development of science and technology, and therefore to a precapitalist forces-relations dialectic. This suggests a new way of appreciating Marx's "ranking" of the Asiatic, ancient, feudal and capitalist modes of production as "progressive epochs" in the development of human society, while illuminating the socio-historical provenance (and sources of variability) of the categories of human thought.

Philosophers and other scholars have often claimed that the arts are not only cognitively valuable but also morally improving (e.g., Nussbaum, 1997). However, their arguments often proceed with little attention to empirical evidence. At the same time, filmmakers and media creators deliberately use devices to direct their audience’s attention, with the intention of impacting viewers’ cognitive, affective, and neurological responses in meaningful ways (Carroll & Seeley, 2013). Whether these devices have the desired effects, and on whom, also remains largely untested. (...) If we want to understand the ways that film and media can have moral impacts, we must step out of our disciplinary siloes. It is not enough for film experts, philosophers, and experimentalists to merely take note of each other’s work; collaborative interdisciplinary research is required, both to improve methods and to examine questions that have not yet been empirically explored. In this article we propose a model for this kind of research, focusing on how media can influence moral understanding. We first outline the challenges that must be met for such research to be successful, including clarifying and operationalizing concepts, measuring moral understanding, and applying empirical methods to media and the arts. We then describe the advantages of interdisciplinary collaboration for meeting these challenges, in the context of some recent examples of interdisciplinary projects on related themes. (shrink)

What is the relationship between detailed critical analysis and the background assumptions made by a given theory of film spectatorship? In this article, I approach this question by looking at Vittorio Gallese and Michele Guerra's The Empathic Screen in the light of the method of triangulation—the coordination and integration of phenomenological, psychological, and neuroscientific evidence, as set out in my Film, Art, and the Third Culture. In particular, I examine Gallese and Guerra's arguments concerning the role of camera movement in (...) prompting immersive, embodied simulation, as well as critiques of these arguments from David Bordwell and Malcolm Turvey. I focus on the special, irreducible role of critical analysis in these arguments. Detailed analysis of film form and style plays an essential role, I argue, in demonstrating the plausibility (or otherwise) of the thesis advanced by Gallese and Guerra. Such analysis is where the rubber of theoretical assumptions meets the road of the material work. (shrink)

The controversy surrounding the status of dialectics in Marxist thought has failed to take the full measure of the persistent influence of ontological dualism and its corollary, dualistic social ontology. Yet an explicit critique of dualism is essential to materialist dialectics and to a Marxist-socialist theory and pedagogy that discloses the specific role of capitalist social relations in impeding human progress. A dialectical-monistic ontology associated with Marx's "new" (historical) materialism requires systematic conceptual elaboration, as illuminated by a dialecticalontological triad embracing (...) "the natural," "the social" and "conscious activity." The usefulness of this triad is illustrated by exploring how dialectical-monistic and dualistic ontologies stimulate very different ways of understanding a key question in social theory: the concept of economic value.

A few years ago I gave a paper on the aesthetics of ‘noise,’ that is, on the ways in which non-musical sounds can be given aesthetic shape and structure, and thereby form the basis of significant aesthetic experience. Along the way I made reference to Arnold Schoenberg's musical theory, in particular his notion of Klangfarbenmelodie, literally ‘sound colour melody,’ or musical form based on timbre or tonal colour rather than on melody, harmony or rhythm. Schoenberg articulated his ideas about Klangfarbenmelodie (...) in the final section of his Harmonielehre. ‘Pitch is nothing else but tone colour measured in one direction,’ wrote Schoenberg. ‘Now, if it is possible to create patterns out of tone colours that are differentiated according to pitch, patterns we call ‘melodies’…then it must also be possible to make such progressions out of the tone colours of the other dimension, out of that which we simply call “tone colour.”’ In other words, traditional melodies work by abstracting and structuring the dominant pitch characterizing a musical sound, while ‘sound colour melodies’ work, Schoenberg argues, by structuring the combined set of pitches contained in a given musical sound. Schoenberg is emphatic that, although a neglected and underdeveloped possibility within Western classical music, ‘sound colour melody’ is a perfectly legitimate and viable form of musical expression; indeed for Schoenberg it is a musical form with enormous potential.

BackgroundUse of modified texture diets—thickening of liquids and modifying the texture of foods—in the hope of preventing aspiration, pneumonia and choking, has become central to the current management of dysphagia. The effectiveness of this intervention has been questioned. We examine requirements for a valid informed consent process for this approach and whether the need for informed consent for this treatment is always understood or applied by practitioners.Main textValid informed consent requires provision of accurate and balanced information, and that agreement is (...) given freely by someone who knows they have a choice. Current evidence, including surveys of practitioners and patients in different settings, suggests that practice in this area is often inadequate. This may be due to patients’ communication difficulties but also poor communication—and no real attempt to obtain consent—by practitioners before people are ‘put on’ modified texture diets. Even where discussion occurs, recommendations may be influenced by professional misconceptions about the efficacy of this treatment, which in turn may poison the well for the informed consent process. Patients cannot make appropriate decisions for themselves if the information provided is flawed and unbalanced. The voluntariness of patients’ decisions is also questionable if they are told ‘you must’, when ‘you might consider’ is more appropriate. Where the decision-making capacity of patients is in question, inappropriate judgements and recommendations may be made by substitute decision makers and courts unless based on accurate information.ConclusionResearch is required to examine the informed consent processes in different settings, but there is ample reason to suggest that current practice in this area is suboptimal. Staff need to reflect on their current practice regarding use of modified texture diets with an awareness of the current evidence and through the ‘lens’ of informed consent. Education is required for staff to clarify the importance of, and requirements for, valid informed consent and for decision making that reflects people’s preferences and values. (shrink)

Murray N. Rothbard (1926–1995) was dean of the Austrian School. He was an economist, economic historian, and libertarian political philosopher. See Murray N. Rothbard's article archives.

The creative process has the potential to increase wellbeing and foster human flourishing (Dolan and Metcalfe, 2012 ; Forgeard and Eichner, 2014 ; O’Brien and Murray, 2015 ; Conner et al., 2018 ; Kaufman, 2018 ), yet has received little attention in the humanistic management literature. In this paper, we present three experiments showing that idea originators experience greater relationship conflict with counterparts who have committed perceived “idea theft”, i.e., proposed identical or related ideas. We test a model that (...) identifies a mechanism—self-threat—that mediates the relationship between idea theft and relationship conflict and identifies an intervention to ameliorate that self-threat via self-affirmation. Study 1 demonstrates the idea originator’s attribution of malign attributions to, and negative moral emotions toward, the counterpart. Study 2 demonstrates that idea originators ostracize both those who propose identical ideas and those who propose merely related ideas. In Study 3, evidence for self-threat as the mechanism underlying the negative relational consequences is provided via both a direct test of mediation as well as via moderation by self-affirmation. Our research contributes to the nascent idea theft literature and suggests a way to reduce its negative consequences. (shrink)

The essential nature of legislative power is to make the laws; that of executive power is to execute those law. The difference between the two is both substantial and significant; it is the difference between the rule of arbitrary power and the rule of law. This paper will seek to trace the genesis of an independent judicial power, in both theory and practice, through an examination of sections of The Constitutions of Clarendon, The Assize of Clarendon, Hobbes’ Leviathan, Locke’s Second (...) Treatise, Montesquieu’s Spirit of the Laws, as well as The Federalist Papers. Moreover, it will seek to establish its executive nature and to explain why it is so often (at least presently) misunderstood to be akin to the legislative power. (shrink)

Very few thinkers have traveled the heretical path that François Laruelle walks between philosophy and non-philosophy. For Laruelle, the future of philosophy is problematic, but a mutation of its functions is possible. Up until now, philosophy has merely been a utopia concerned with the past and only provided the services of its conservation. We must introduce a rigorous and nonimaginary practice of a utopia in action, a philo-fiction—a close relative to science fiction. From here we can see the double meaning (...) of the watchword, a tabula rasa of the future. This new destination is imposed by a specifically human messianism, an eschatology within the limits of the Man-in-person as antihumanist ultimatum addressed to the History of Philosophy. This book elucidates some of the fundamental problems of non-philosophy and takes on its detractors. (shrink)

Accounting educators are being called on to provide a greater emphasis on ethics education. This paper examines three important issues concerning ethics education in accounting. First, the question of whether ethics can indeed be taught is examined. Next, several innovative approaches are presented which have been used by accounting educators to integrate ethics into the classroom. Finally, results of a survey of students concerning their perspectives of ethical issues in accounting education, the accounting profession, and society at large are presented (...) and discussed. Survey results reveal that students consider a lack of ethics damaging to the accounting profession and society. Results also indicate that accounting students are seeking ethical and moral direction. (shrink)
