White matter tracts are known to be susceptible to injury following concussion. The objective of this study was to determine whether contact play in sport could alter white matter metabolite levels in female varsity athletes independent of changes induced by long-term exercise. Metabolite levels were measured by single voxel proton magnetic resonance spectroscopy in the prefrontal white matter at the beginning and end of season in contact and non-contact varsity athletes. Sedentary women were scanned once, at a time equivalent to (...) the Off-Season time point. Metabolite levels in non-contact athletes did not change over a season of play, or differ from age matched sedentary women except that non-contact athletes had a slightly lower myo-inositol level. The contact athletes had lower levels of myo-inositol and glutamate, and higher levels of glutamine compared to both sedentary women and non-contact athletes. Lower levels of myo-inositol in non-contact athletes compared to sedentary women indicates long-term exercise may alter glial cell profiles in these athletes. The metabolite differences observed between contact and non-contact athletes suggest that non-contact athletes should not be used as controls in studies of concussion in high-impact sports because repetitive impacts from physical contact can alter white matter metabolite level profiles. It is imperative to use athletes engaged in the same contact sport as controls to ensure a matched metabolite profile at baseline. (shrink)

SUMMARYSchleiermacher's doctrine of the Trinity is constituted not only by his Glaubenslehre but also in Über den Gegensatz zwischen der Sabellianischen und der Athanasianischen Vorstellung von der Trinität . Schleiermacher can be seen to construe the persons of the Trinity as the circumscription of divinity. This point leads to consideration of divine wisdom as the ground of both the immanent and economic Trinity.

Vocal affect is a subcomponent of emotion programs that coordinate a variety of physiological and psychological systems. Emotional vocalizations comprise a suite of vocal behaviors shaped by evolution to solve adaptive social communication problems. The acoustic forms of vocal emotions are often explicable with reference to the communicative functions they serve. An adaptationist approach to vocal emotions requires that we distinguish between evolved signals and byproduct cues, and understand vocal affect as a collection of multiple strategic communicative systems subject to (...) the evolutionary dynamics described by signaling theory. We should expect variability across disparate societies in vocal emotion according to culturally evolved pragmatic rules, and universals in vocal production and perception to the extent that form–function relationships are present.

What makes any investigative field a scientific discipline? This article argues that disciplines are ever-changing frameworks within which scientific activity is organised. Moreover, disciplinarity is not a yes or no proposition: scientific activities may achieve degrees of identity development. Degree of consensus is the key, and consensus on many questions (conceptual, methodological, institutional, and social) varies among sciences. Lastly, disciplinary development is non-teleological. Disciplines pass through no regular stages on their way from immature to mature status, designations articulated within the (...) rhetoric of discipline formation. Scientists assemble disciplines using many elements: phenomena, methods, instruments, theories, analytical techniques, and institutional tools such as journals, government bureaus, and university positions. Scientists created geophysics during the nineteenth and twentieth centuries through such a combination. Whether geophysics became a discipline depends on how discipline is defined. (shrink)

The thirteenth century mystic Ibn ʻArabi was the foremost Sufi theorist of the premodern era. For more than a century, Western scholars and esotericists have heralded his universalism, arguing that he saw all contemporaneous religions as equally valid. In Rethinking Ibn ʻArabi, Gregory Lipton calls this image into question and throws into relief how Ibn ʻArabi's discourse is inseparably intertwined with the absolutist vision of his own religious milieu-- that is, the triumphant claim that Islam fulfilled, superseded, and therefore (...) abrogated all previous revealed religions. Lipton juxtaposes Ibn ʻArabi's absolutist conception with the later reception of his ideas, exploring how they have been read, appropriated, and universalized within the reigning interpretive field of Perennial Philosophy in the study of Sufism. The contours that surface through this comparative analysis trace the discursive practices that inform Ibn ʻArabi's Western reception back to the eighteenth and nineteenth century study of 'authentic' religion, where European ethno-racial superiority was wielded against the Semitic Other - both Jewish and Muslim. Lipton argues that supersessionist models of exclusivism are buried under contemporary Western constructions of religious authenticity in ways that ironically mirror Ibn ʻArabi's medieval absolutism.

Verbal irony constitutes a rough class of indirect intentional communication involving a complex interaction of language-specific and communication-general phenomena. Conversationalists use verbal irony in conjunction with paralinguistic signals such as speech prosody. Researchers examining acoustic features of speech communication usually focus on how prosodic information relates to the surface structure of utterances, and often ignore prosodic phenomena associated with implied meaning. In the case of verbal irony, there exists some debate concerning how these prosodic features manifest themselves in conversation. A (...) form-function approach can provide a valuable tool for understanding speakers' varied vocal strategies in this domain. Here I describe several ways conversationalists employ prosodic contrasts, laughter, and other speech characteristics in their attempts to communicate effectively and efficiently. The presented examples, culled from spontaneous conversation recordings, reveal just a small sample of the enormous variation in delivery styles speakers adopt when communicating with ironic language.

We explored the differential impact of auditory information and written contextual information on the recognition of verbal irony in spontaneous speech. Based on relevance theory, we predicted that speakers would provide acoustic disambiguation cues when speaking in situations that lack other sources of information, such as a visual channel. We further predicted that listeners would use this information, in addition to context, when interpreting the utterances. People were presented with spontaneously produced ironic and nonironic utterances from radio talk shows in (...) written or auditory form, with or without written contextual information. When the utterances were read without written contextual information, all utterances were rated as equally ironic. But when they were heard as opposed to read, or when they were presented in irony-biasing contexts, originally ironic utterances were rated as more sarcastic than originally nonironic utterances. This evidence suggests both acoustic and contextual information are used when inferring ironic intent in spontaneous speech, and validates previous manipulations of intonation in studies of irony understanding.

Sumantra Ghoshal’s condemnation of “bad management theories” that were “destroying good management practices” has not lost any of its salience, after a decade. Management theories anchored in agency theory (and neo-classical economics generally) continue to abet the financialization of society and undermine the functioning of business. An alternative approach (drawn from a more classic institutional, new ecological, and refocused ethical approaches) is reviewed.

This book joins a small number of efforts in the last decade to present the complex scientific issues of geomagnetism to a broader, semi-technical audience. The author approaches this goal more closely than most scientists and science writers. He specifically eschews mathematical equations knowing that even one equation leads some readers to give up trying. He offers instead a mix of description and story-telling, the former directed at phenomena and procedures, the latter drawn mostly from personal experience.As Merrill notes, his (...) wife insisted that he “explain the material in a way she could understand it” (vii). A virtue of this is an enforced candor often obscured by mathematics, even in semi-popular accounts. This is most clear in addressing fundamental questions, such as when he asks what produces the magnetic field of magnets. In a paragraph that begins with a simple bar magnet, the author successively halves the magnet until he has only an electron remaining. This he calls a po. (shrink)

This paper examines the status of naturalism in the philosophies of Edmund Husserl and John Dewey. Despite the many points of overlap and agreement between Husserl’s and Dewey’s philosophical projects, there remains one glaring difference, namely, the place and status of naturalism in their approaches. For Husserl, naturalism is an enemy to be vanquished. For Dewey, naturalism is the only method that can put philosophy back in touch with the concerns of human beings. This paper will demonstrate the remarkable similarities (...) between Husserl’s and Dewey’s thought before contending that Dewey’s “naturalistic humanism” offers a conception of naturalism which is compatible with Husserlian phenomenology. Furthermore, reading these two philosophers together, this paper argues, can point the way forward to a naturalism which avoids the dismissal of the contributions made by knowing subjects carried out by dominant contemporary strains of reductive naturalism.

The usual problems of measurement and its meaning are complicated and magnified when the object of study is in principle and in fact inaccessible. When a phenomenon occurs in a place where our instruments cannot reach, what can the relation between the instrument, its reading, and the phenomenon be? This essay asks how researchers have addressed questions about inaccessible processes of Earth's magnetic field on the surface, at the edge of space and under its surface. This case takes us beyond (...) simple contrasts of inductive and deductive methods, or field sciences versus basic sciences, to a messier, more nuanced view of inherently complex sciences. The article focuses on investigations of Earth's magnetism and electricity, but its perspectives are applicable to many areas of recent science. (shrink)

Throughout his career, Jean-Paul Sartre had a contentious theoretical relationship with psychoanalysis. Nowhere is this more evident than in his criticisms of the concept of the unconscious. For him, the unconscious represents a hidden psychological depth that is anathema to the notion of human freedom. In this paper, I argue that Lacan’s conception of the unconscious-structured-like-a-language overcomes many of Sartre’s most damning objections. I demonstrate that Lacan shares with Sartre a concern to rid the psyche of hidden depths. Both thinkers (...) therefore reject the depth psychological conception of the unconscious and arrive at strikingly similar positions on the nature of the unconscious. In this way, I show that the conceptual analogues that Sartre develops in order to avoid the psychoanalytic unconscious lead him to a position on the unconscious with which Lacan could be in agreement. This indicates that Sartre’s philosophical position is not as at odds with Freudian-Lacanian psychoanalysis as is typically thought. (shrink)

Stoffregen & Bardy suggest that the global array provides the specification that is lacking when senses are considered in isolation. This seems to beg the question of the minimum number of senses in a global array. Individuals with sensory loss manage with fewer senses, and humans manage with fewer than electric fish; so specification, if it exists, cannot require all possible senses.

Schizophrenia patients exhibit impairments across multiple clinical, cognitive, and functional domains. A fundamental abnormality of the timing and/or efficiency of neural processes across disparate brain regions (i.e., cortico-cortical communications) may underlie many of the deficits in schizophrenia. Because gamma synchrony is temporally correlated with many cognitive processes, probing patterns of gamma activation may shed light on the functional integrity of neural circuits in schizophrenia and related disorders.

Jesus instructs us to “love,” “pray for,” and “do good” to enemies, going so far as to make this response to enemies the criterion for being considered “children of your Father in heaven”. Jesus based this instruction on the character of the Father, not on the character of our enemies, which means his instruction allows for no exceptions. In this essay I flesh out the implications of this for a Christian response to terrorism, arguing that this response should look radically (...) different from that of just war theorists. (shrink)

A crucial factor in how we perceive social groups involves the signals and cues emitted by them. Groups signal various properties of their constitution through coordinated behaviors across sensory modalities, influencing receivers' judgments of the group and subsequent interactions. We argue that group communication is a necessary component of a comprehensive computational theory of social groups.

Carruthers has proposed a novel and quite interesting hypothesis for the role of language in conceptual integration, but his treatment does not acknowledge work in cognitive science on metaphor and analogy that reveals how diverse knowledge structures are integrated. We claim that this body of research provides clear evidence that cross-domain conceptual connections cannot be driven by syntactic processes alone.

This dissertation reassesses the complex philosophical relationship between Sartre and psychoanalysis. Most scholarship on this topic focuses on Sartre’s criticisms of the unconscious as anathema both to his conception of the human psyche as devoid of any hidden depths or mental compartments and, correlatively, his account of human freedom. Many philosophers conclude that there is little common ground between Sartrean existentialism and psychoanalytic theory. I argue, on the contrary, that by shifting the emphasis from concerns about the nature of the (...) unconscious to questions about the role of imagination in psychical life, we can see that Sartre and Freudian-Lacanian psychoanalytic theory develop strikingly similar accounts of human subjectivity. After establishing the historical background of Sartre’s career-long engagement with psychoanalysis, I demonstrate the proximity of Sartre and Lacan on the nature of unconscious thought. I proceed to develop the claim that there is a homology between the concept of unconscious fantasy in psychoanalysis and the concept of the imaginary in Sartre’s philosophical corpus. Despite the concept of fantasy being one of the more structuralist-inspired aspects of Lacan’s metapsychology, I show that Sartre’s concept of the imaginary is likewise a structural feature of the psyche, one which establishes the coordinates within which the subject engages with the world. For Sartre, Freud, and Lacan fantasies form the core of subjectivity, giving form to the basic patterns of one’s character. Taken together, these three thinkers furnish a nuanced view of fantasy/the imaginary. On the one hand it is determining insofar as it is responsible for many of the psychopathologies met with in psychoanalysis. On the other hand, it is liberating insofar as the agency of the subject is implicated in the formation of fantasy. I thereby show that Sartre does not fit the caricatured picture of a radical voluntarist that is often attributed to him and that psychoanalysis can accommodate a conception of human freedom.

Paul Ricœur’s hermeneutic approach to psychoanalysis stresses the interpretation of meanings revealed via the narratives woven through the discursive exchanges between analyst and analysand. Despite the tremendous influence Ricœur’s interpretation enjoyed both in philosophy and in psychoanalysis, his approach has been subject to severe criticism by Adolf Grünbaum who argues that Freud modeled psychoanalysis on the natural sciences, and therefore it should be judged according to natural scientific standards. I argue that Grünbaum incorrectly downplays the importance of speech and language (...) in psychoanalytic theory and practice, and moreover, that Ricœur’s approach offers important insights that deserve to be redeployed today.

Edward Harold Fulcher Swain (1883?1970) developed a unique idea about the importance of forests, advocating the creation of a new society based upon forests, and he pursued policies to implement his unique vision of forestry when he served as the Director of Queensland's Forestry Board from 1918 to 1924 and the Forestry Commissioner for New South Wales from 1935 to 1948. Swain's beliefs developed out of a combination of his Australian experiences and connections with foresters in the British Empire and (...) America. When he could not convince Australian elites about the need to create a forest-based society, he asked foresters at the 1947 Empire Forestry Conference in London to assert the primacy of forestry in land management in the British Empire. Many foresters positively received parts of Swain's argument, but his ideas could never be fully implemented in the British Empire because of the dominance of agrarian doctrines of development in post-Second World War colonial planning and the rapid process of decolonization. Swain's life sheds light onto current debates among historians about the origin and legacy of forestry in Australia and the British Empire. His ideas, many that parallel the basic tenets of modern environmentalism, require historians to rethink the relationship between Empire forestry and environmentalism. (shrink)
