Bidirectional deep brain stimulation (DBS) platforms have enabled a surge in hours of recordings in naturalistic environments, allowing further insight into neurological and psychiatric disease states. However, high amplitude, high frequency stimulation generates artifacts that contaminate neural signals and hinder our ability to interpret the data. This is especially true in psychiatric disorders, for which high amplitude stimulation is commonly applied to deep brain structures where the native neural activity is miniscule in comparison. Here, we characterized artifact sources in recordings (...) from a bidirectional DBS platform, the Medtronic Summit RC + S, with the goal of optimizing recording configurations to improve signal to noise ratio (SNR). Data were collected from three subjects in a clinical trial of DBS for obsessive-compulsive disorder. Stimulation was provided bilaterally to the ventral capsule/ventral striatum (VC/VS) using two independent implantable neurostimulators. We first manipulated DBS amplitude within safe limits (2–5.3 mA) to characterize the impact of stimulation artifacts on neural recordings. We found that high amplitude stimulation produces slew overflow, defined as exceeding the rate of change that the analog to digital converter can accurately measure. Overflow led to expanded spectral distortion of the stimulation artifact, with a six fold increase in the bandwidth of the 150.6 Hz stimulation artifact from 147–153 to 140–180 Hz. By increasing sense blank values during high amplitude stimulation, we reduced overflow by as much as 30% and improved artifact distortion, reducing the bandwidth from 140–180 Hz artifact to 147–153 Hz. We also identified artifacts that shifted in frequency through modulation of telemetry parameters. We found that telemetry ratio changes led to predictable shifts in the center-frequencies of the associated artifacts, allowing us to proactively shift the artifacts outside of our frequency range of interest. Overall, the artifact characterization methods and results described here enable increased data interpretability and unconstrained biomarker exploration using data collected from bidirectional DBS devices.

Scholars have a history of crossing intellectual borders (Abbott, 2001). In particular, educators draw from a diversity of intellectuals upon which to base our understanding of, for example, schools and society, curriculum content, teaching, and learning. In addition to icons such as Marx, James, Freud, and Dewey, the works of the Frankfurt School (e.g., Horkheimer, Adorno, Marcuse), Foucault, Gilligan, Derrida, Gramsci, West, Arendt, and Fraser, just to name a few, have been used to guide our scholarship and practice. However, with (...) the exception of few scholars (e.g., Peters & Ghiraldelli, 2001), one of America's most controversial scholars,1 Richard Rorty, has been largely ignored. This situation is unfortunate .. (shrink)

Dans The Elements of Drawing, le célèbre critique d’art anglais John Ruskin endosse le rôle de professeur pour livrer, en trois longues lettres adressées aux débutants, son enseignement sur l’art du dessin. De cet ouvrage hybride, mêlant exercices, observations sur les couleurs, commentaires de peintures et descriptions lyriques de la nature, la postérité retiendra principalement un court passage sur la formation de la perception. Dans une note de bas de page du premier chapitre, Ruskin nous dit en effet que « (...) toute la force de la technique picturale dépend de la possibilité pour nous de retrouver ce que nous pourrions appeler l’innocence de l’œil ». Cette note célèbre a fait l’objet de nombreux commentaires (chez E. Gombrich et N. Goodman notamment), qui viennent discuter, et souvent réfuter, la possibilité d’un regard vierge. À rebours des lectures de surplomb qui autonomisent ce passage et le transforment en « théorie », nous proposons de revenir au texte de Ruskin en pensant l’innocence de l’œil dans son articulation singulière et fondatrice aux exercices qui l’accompagnent. L’hypothèse que nous soumettons est la suivante : c’est l’exercice, dans sa conduite réitérée, qui permet de comprendre le sens de l’innocence perceptive. Bien loin d’un apprentissage scolaire, l’exercice du regard engage chez Ruskin une manière d’être au monde. (shrink)

Many languages grammatically mark evidentiality, i.e., the source of information. In assertions, evidentials indicate the source of information of the speaker while in questions they indicate the expected source of information of the addressee. This dissertation examines the semantics and pragmatics of evidentiality and illocutionary mood, set within formal theories of meaning and discourse. The empirical focus is the evidential system of Cheyenne (Algonquian: Montana), which is analyzed based on several years of fieldwork by the author.

This book provides a compositional, truth-conditional, crosslinguistic semantics for evidentiality, the linguistic encoding of the source of information on which a statement is based. Central to the proposed theory is the distinction between what propositional content is at-issue and what content is not-at-issue. Evidentials contribute not-at-issue content, and can affect the level of commitment a sentence makes to the main proposition, contributed by sentential mood. In this volume, Sarah Murray builds on recent work in the formal semantics of evidentials (...) and related phenomena, and proposes a semantics that does not appeal to separate dimensions of illocutionary meaning. Instead, she argues that all sentences make three contributions: at-issue content, not-at-issue content, and an illocutionary relation. At-issue content is presented and made available for subsequent anaphora, but is not directly added to the common ground; not-at-issue content directly updates the common ground; and the illocutionary relation uses the at-issue content to impose structure on the common ground, which, depending on the clause type, can trigger further updates. 0The analysis is supported by extensive empirical data from Cheyenne, drawn from the author's own fieldwork, as well as from English and a variety of other languages.

Following on the heels of his critically acclaimed God of Abraham, Lenn E. Goodman here focuses on rights, their grounding in the deserts of beings, and the dignity of persons. In an incisive contemporary dialogue between reason and revelation, Goodman argues for ethical standards and public policies that respect human rights and support the preservation of all beings: animals, plants, econiches, species, habitats, and the monuments of nature and culture. Immersed in the Jewish and philosophical sources, Goodmans argument (...) ranges from the fetus in the womb to the modern nation state, from the problems of pornography and tobacco advertising to the rights of parents and children, individuals and communities, the powerful and powerless--the most ancient and the most immediate problems of human life and moral responsibility. Guided by the probing argumentation that Goodman lays out with distinctive, often poetic clarity, the reader will emerge enlightened and prepared to respond with intelligence and commitment to the sobering moral challenges of the coming century. This is a book for anyone concerned with law, ethics, and the human prospect. (shrink)

Bodily methodologies that engage with the affective, rhythmic, and temporal dimensions of movement have altered the landscape of social science and humanities research. Walking is one such methodology by which scholars have examined vital, sensory, material, and ephemeral intensities beyond the logics of representation. Extending this rich field, this article invokes the concept trans to reconceptualize walking research through theories that attend to the vitality and agency of matter, the interconnectedness between humans and non-humans, the importance of mediation and bodily (...) affect, and the necessity of acknowledging ethico-political responsibility. While theoretical and empirical research about embodied, emplaced, and sensorial relations between moving bodies and space are well developed in the field of walking studies, their entanglements become profoundly altered by theories of trans – transcorporeality, transspecies, and transmaterialities. Taking up trans theories we experiment in thinking-with a sonic art performance, Walking to the Laundromat, which probes bodily, affective, and gendered labour. (shrink)

On one view, the point of an assertion is to update the common ground (Stalnaker 1978, Karttunen 1974). On another, the point of an assertion is to propose an update to the com- mon ground (Groenendijk 2009, Mascarenhas 2009, and related work on the structure of discourse, e.g., Ginzburg 1996, Roberts 1996, Gunlogson 2001). In Murray (to appear), I merge these two views. I argue based on evidence from declarative sentences with eviden- tials that assertion has two components: what is (...) at-issue and what is not. The not-at-issue component of assertion is added directly to the common ground while the at-issue compo- nent is proposed to be added to the common ground. Here, I extend this analysis to yes/no questions in Cheyenne and their interaction with evidentials. I propose that the distinction between what is at-issue and what is not is also present in questions, and that it can be modeled in the same way. Specifically, both declarative and interrogative sentences make two contributions: they restrict and structure the common ground. The restriction is based on the not-at-issue component while the structuring relation is based on the at-issue component. (shrink)

The purpose of this paper is to review critically Julian Savulescu's principle of 'Procreative Beneficence,' which holds that prospective parents are morally obligated to select, of the possible children they could have, those with the greatest chance of leading the best life. According to this principle, prospective parents are obliged to use the technique of pre-implantation genetic diagnosis (PGD) to select for the 'best' embryos, a decision that ought to be made based on the presence or absence of both disease (...) traits and non-disease traits such as intelligence. While several articles have been written in response to Savulescu's principle, none has systematically explored its philosophical underpinnings to demonstrate where it breaks down. In this paper I argue that the examples that Savulescu employs to support his theory in fact fail to justify it. He presents these examples as analogous to PGD, when in fact they differ from it in subtle but morally relevant ways. Specifically, Savulescu fails to acknowledge the fact that his examples evoke deontological and virtue ethics concerns that are absent in the context of PGD. These differences turn out to be crucial, so that, in the end, the analogies bear little support for his theory. Finally, I lay out the implications of this analysis for reproductive ethics.

School gardens and garden-based learning continue to gain great popularity in the United States, and their pedagogical potential, and ability to impact students’ fruit and vegetable consumption and activity levels have been well-documented. Less examined is their potential to be agents of food system reskilling and transformation. Though producer and consumer are inextricably linked in the food system, and deskilling of one directly influences the other, theorists often focus on production-centered and consumption-centered deskilling separately. However, in a school garden, the (...) production/consumption disconnect is erased, by virtue of the design of the site itself and how it is utilized by the actors within it. School gardens provide the critical component of education in alternative food networks, and contribute to the producer/consumer reskilling that is a necessary part of food system transformation. We conducted a case study of an established school garden program during its transition from autonomous non-profit to official, district-funded program of a rural school district in the Midwest. By participating in the full “seed to plate” life cycle of a garden crop, students in the garden were actively involved in the reconnection of producer and consumer, while educators were fostering in students an appreciation for fresh, healthy foods and actively challenging the “McDonaldization” of both students’ diets and education. Based upon these findings, we argue that school gardens in rural areas could leverage the dominant role of rural America in developing and shifting food system paradigms. (shrink)

Philosophers of literature direct their studies to the moral, cognitive, and emotional aspects of our involvement with fiction. In spite of this, they rarely engage works of popular fiction. In this paper I use The Da Vinci Code as a case study of the impact of popular fiction on readers in terms of these three areas. Although this book will never be considered good literature, its impact is far reaching. l address concerns dealing with the fiction/non-fiction distinction as weIl as (...) issues with history, accuracy, and falsehoods. I flesh out the issues The Da Vinci Code brings up and argue that it, along with other works of popular fiction (Oprah’s book club for example), might be taken more seriously by philosophers of literature.

This paper discusses three potential varieties of update: updates to the common ground, structuring updates, and updates that introduce discourse referents. These different types of update are used to model different aspects of natural language phenomena. Not-at-issue information directly updates the common ground. The illocutionary mood of a sentence structures the context. Other updates introduce discourse referents of various types, including propositional discourse referents for at-issue information. Distinguishing these types of update allows a unified treatment of a broad range of (...) phenomena, including the grammatical evidentials found in Cheyenne (Algonquian) as well as English evidential parentheticals, appositives, and mood marking. An update semantics that can formalize all of these varieties of update is given, integrating the different kinds of semantic contributions into a single representation of meaning. (shrink)

In this fascinating book, Sarah Worth addresses from a philosophical perspective the many ways in which reading benefits us morally, socially and cognitively.

In this paper, I propose that the distinction between what is at-issue and what is not can be modeled as a distinction between two components of assertion. These two components affect the common ground in different ways. The at-issue component of an assertion, which is negotiable, is treated as a proposal to update the common ground. The not-at-issue component of an assertion, which is not negotiable, is added directly to the common ground. Evidence for this proposal comes from evidentials, which (...) I argue grammaticize this distinction. It has been observed that sentences with evidentials make both an ‘evidential’ and a ‘propositional’ contribution (Faller 2002, 2006, Matthewson et al. 2008). The evidential contribution is not directly challengeable or up for negotiation. In contrast, the propositional contribution, the ‘main point’ of the sentence, is directly challengeable and up for negotiation. I analyze these two contributions of evidentials as the not-at-issue component of assertion and the at-issue component of assertion, respectively. Supporting data comes from Cheyenne, a language with evidentials that are part of the illocutionary mood paradigm. (shrink)

Sarah E. Wilson, University of Central LancashireThis paper's account of the core issues at stake in relation to genetic enhancement is presented as an alternative to mainstream liberal defenses of enhancement. The mainstream arguments are identified as being associated with reproductive autonomy, individual choice, and a `neutral', passive interpretation of technology. The alternative account is associated with the perspective of `woman' or child-bearer, with a fundamental concern for social justice, and an understanding of society in both a global and (...) a contextual sense. This paper adopts a theoretical framework informed by feminist ethics, particularly a feminist ethic of care. The paper begins by outlining some of the key points of the care perspective, highlighting how this contrasts with a mainstream `justice' perspective, and illustrating how this is reflected in arguments relating to genetic enhancement. The paper then turns to a consideration of how a care perspective might be applied to questions of genetic enhancement, and how this may bring forward new issues. This includes in particular a consideration of IVF technologies and how applying understandings from research into this area brings forward usually unaddressed concerns in considering genetic enhancement. The final section of the paper covers some of the questions that there is space to ask once the narrow focus on individual rights is overcome. (shrink)

In this paper, I discuss the quantificational variability of Cheyenne indeterminates: the variety of interpretations they can receive and the grammatical contexts that condition these interpretations. Building on analyses of indeterminates in other languages, such as Kratzer and Shimoyama (2002), I present a Hamblin-style analysis of Cheyenne indeter- minates. The proposal builds on the analysis of declaratives and interrogatives argued for in Murray (2010). This analysis can account for the quantificational variability of indeterminates in the scope of propositional operators as (...) well as the scope of illocutionary mood markers. The analysis is formalized in an independently motivated update semantics (Update with Centering, Bittner 2011), which automatically provides the required alternatives. (shrink)

Nuclear speckles are eukaryotic nuclear bodies enriched in splicing factors. Their exact purpose has been a matter of debate. The different proposed roles of nuclear speckles are reviewed and an additional layer of function is put forward, suggesting that by accumulating splicing factors within them, nuclear speckles can buffer the nucleoplasmic levels of splicing factors available for splicing and thereby modulate splicing rates. These findings build on the already established model that nuclear speckles function as a storage/recycling site for splicing (...) factors. Many studies have demonstrated proximity between nuclear speckles and sites of active transcription, suggesting that this juxtaposition can enhance the rates of gene expression. It is found that nuclear speckle disassembly increases splicing factor availability in the nucleoplasm, leading to an increase in splicing rates and faster release of nascent transcripts from the gene after transcription. Altogether, this era in which genomic and imaging approaches are applied to study nuclear organization has expanded the outlook on the possible roles of nuclear speckles. (shrink)

Although environmental ethicists often focus on applying ethics to policy, the ethics embedded in policy documents such as Agenda 21 are also significant. Though largely ignored by ethicists after early responses to the document focused on intrinsic value, Agenda 21's ethics are particularly valuable for their ability to resonate with many people and link politics, technical studies, and ethics. For instance, their use draws attention to the need to ethically evaluate sustainability indexes and identifies limitations of existing indexes. At a (...) broad level, this study of the ethics of Agenda 21 also suggests that the ethics of international environmental policy documents deserves more attention. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peaceful Persuasion: The Geopolitics of Nonviolent RhetoricSarah E. DempseyPeaceful Persuasion: The Geopolitics of Nonviolent Rhetoric. Ellen W. Gorsevski. Albany: State University of New York Press, 2004.pp. 262. $55.00, hardcover.The overriding emphasis on violence, militarization, and retribution within current geopolitical contexts demands that we acquire greater understandings of nonviolent communicative practices. In Peaceful Persuasion, author Ellen Gorsevski, Professor of English and Communication at Oregon State University, argues that nonviolent (...) rhetoric tends to be ignored by scholars—that its methods, strategies, and impacts are often passed over and that nonviolence is often framed as hopelessly utopian, unrealistic, and ineffective. Gorsevski situates her study of nonviolent rhetoric less within its humanistic and religious inheritance, drawing instead on a contrast with existing models of rhetoric. As a strategy for rhetorical and political action, Gorsevski takes nonviolence to be instructive of new ways to reconfigure both rhetorical studies and social movement strategy.It is important to note that Gorsevski's need to study peaceful means of relating to others is driven as much by a love of rhetorical theory as by a passion for translating an understanding of nonviolent rhetoric into strategies for activists. As such, this book provides a solid introduction to rhetorical theory, including an appendix on the connection between rhetoric and nonviolence that details what activists have to gain from each. In addition, instructors will find useful a chapter on the specifics of incorporating nonviolence into speech communication classrooms.Peaceful Persuasion's greatest contribution to rhetorical studies is the careful drawing out of the many ways that a rhetorical take on nonviolence has become increasingly necessary. To make this solid case, Gorsevski draws on four very diverse case studies of nonviolent rhetoric. In a move that is both surprising and refreshing, Gorsevski's case studies do more than provide exemplars of how critics may read nonviolence as a powerful rhetorical strategy; each helps to further delineate the key characteristics of what has been, until now, a relatively undefined area of rhetorical action.Gorsevski's gift to her readers is the ability to demonstrate the rich subtleties of nonviolence through very different contexts. The case studies [End Page 89] draw from such different sources that at first seem disorienting. Upon reflection, it becomes clearer that they greatly complicate our notions of nonviolence, redressing the disservices of previous bleary analyses that configured nonviolence only by its lack of violence rather than according to its fruitful range of seemingly contradictory strategies. The cavernous distances each study crosses illuminate the multiplicity of forms, meanings, and strategies that nonviolence may take. As such, any definition of nonviolence that I may provide in this short review does a serious disservice to the depth that Gorsevski creates through her sometimes disjointed case studies.The case studies serve at least dual purposes, as each provides an analysis that extends our understandings of nonviolence in action as it also offers instructive mini-lessons for the further development of rhetorical studies. In the first case study, Gorsevski provides a contextualized analysis of critics' interpretations of the film The Spitfire Grill, which she shows to be reflective of the "predominantly accepting orientation that rhetoric and film critics hold for the idea that humans are characterized by "innate aggression" and violence" (68). For Gorsevski, this study demonstrates that nonviolence as a lens can be applied to a range of texts just as well as any other approach to rhetoric. Gorsevski moves her analysis of nonviolent rhetoric into the geopolitical realm for her study of President of Macedonia Kiro Gligorov's historic first speech before the United Nations. She takes his speech as evidence of the usefulness of pragmatic nonviolence, which entails "noncooperation or defiance of political adversaries in order to decry a perceived injustice" (72). Gligorov's speech illustrates that nonviolence and violence are best seen less as equivalent than, rather, as operating on a sliding scale. For Gorsevski, successful use of pragmatic nonviolence may even include a measure of violence as long as it serves to reduce the escalation of further strife.Next Gorsevski explores the visual rhetoric of the gendered body of Burmese activist and Nobel Peace Prize winner Aung San Suu Kyi to show...

Language and culture endow humans with access to conceptual information that far exceeds any which could be accessed by a non-human animal. Yet, it is possible that, even without language or specific experiences, non-human animals represent and infer some aspects of similarity relations between objects in the same way as humans. Here, we show that monkeys’ discrimination sensitivity when identifying images of animals is predicted by established measures of semantic similarity derived from human conceptual judgments. We used metrics from computer (...) vision and computational neuroscience to show that monkeys’ and humans’ performance cannot be explained by low-level visual similarity alone. The results demonstrate that at least some of the underlying structure of object representations in humans is shared with non-human primates, at an abstract level that extends beyond low-level visual similarity. Because the monkeys had no experience with the objects we tested, the results suggest that monkeys and humans share a primitive representation of object similarity that is independent of formal knowledge and cultural experience, and likely derived from common evolutionary constraints on object representation.

We recommend that the future of religion and science involve more partnerships between scholars, amateurs, and artists. This reimagines an underdeveloped aspect of the history of religion and science. Case studies of an undergraduate course examining religious ritual and technology, seminarians reflecting on memory and identity in light of Alzheimer's disease, environmentalists responding to their guilt and shame about climate change, and Chicagoans recognizing the presence of nature in the city show how these partnerships respect insights and experiences of our (...) varied partners, identify and resolve community problems, and advance scholarship.

Any evolved disposition for fairness and cooperation would not replace but merely compete with selfish and other antisocial impulses.

Plural reflexives and reciprocals are anaphoric not only to antecedent pluralities but also to relations between the members of those pluralities. In this paper, I utilize Dynamic Plural Logic (van den Berg 1996) to analyze reflexives and reciprocals as anaphors that elaborate on relations introduced by the verb, which can be collective, cumulative, or distributive. This analysis generalizes to languages like Cheyenne (Algonquian) where reflexivity and reciprocity are expressed by a single proform that I argue is underspecified, not ambiguous.

Although the dynamic field model predicts infants' perseverative behavior in the context of the A-not-B manual search task, it does not account for infant perseveration in other contexts. An alternative cognitive capacity explanation for perseveration is more parsimonious. It accounts for the graded nature of perseverative responses and perseveration in different contexts.

In languages like English, reflexivity and reciprocity are expressed by distinct proforms. However, many languages, such as Cheyenne, express reflexivity and reciprocity with a single proform. In this paper I utilize Dynamic Plural Logic (van den Berg, 1996) to a draw a semantic parallel between reflexive and reciprocal anaphors in English. I propose that they contribute overlapping but distinct requirements on the relations introduced by transitive verbs, requirements which fully specify reflexivity and reciprocity. This parallel is then extended to Cheyenne (...) by appealing to underspecification. I propose the Cheyenne affix which expresses both reflexivity and reciprocity contributes only the shared requirement of the English anaphors. It is thus underspecified, not ambiguous. This accounts for its compatibility with both singular and plural antecedents as well as its variety of construals. (shrink)

ABSTRACTIn 1651, Alexander Ross published an attack on Thomas Browne's Pseudodoxia Epidemica, Bacon's Natural History and William Harvey's De generatione. Ross's work, Arcana Microcosmi, defended Aristotelian natural philosophy against the ‘new philosophy’ that figures like Bacon, Harvey and Browne represented. Though Ross's attacks on these authors make up no more than half of the treatise’s contents, the book’s paratextual materials emphasise scientific debate. While Ross's authorial approach advocates reading exclusively ancient authorities for the sake of glossing and transmitting their knowledge (...) to a wider public, in order to argue against the new philosophy Ross must engage with its textual production. Furthermore, his works advertise their focus on Bacon, Harvey and Browne, which would have attracted a readership drawn to new scientific approaches to knowledge formation. Ross's polemic represents an effort to model his devotion to ancient authority while also generating a reading public that would resist the new approach to reading that the new philosophy proposed.

Across cultures, people employ space to construct representations of time. English exhibits two deictic space–time metaphors: the “moving ego” metaphor conceptualizes the ego as moving forward through time and the “moving time” metaphor conceptualizes time as moving forward towards the ego. Earlier research investigating the psychological reality of these metaphors has shown that engaging in certain types of spatial-motion thinking may influence how people reason about events in time. More recently, research has shown that people’s interactions with cultural artifacts may (...) also influence their representations of time. Extending research on space–time mappings in new directions, three experiments investigated the role of cultural artifacts, namely calendars and clocks, in the interpretation of metaphorical expressions about time. Taken together, the results provide initial evidence that, in their interpretation of ambiguous metaphorical expressions about time, people automatically access and use spatial representations of absolute time, whereby moving forward in space corresponds with moving later in time. Moreover, asking participants to use a reverse space–time mapping causes interference, which is reflected through their temporal reasoning. (shrink)

To ensure accurate chromosome segregation during mitosis, the spindle checkpoint monitors chromosome alignment on the mitotic spindle. Indjeian and colleagues have investigated the precise role of the shugoshin 1 protein (Sgo1p) in this process in budding yeast.1 The Sgo proteins were originally identified as highly conserved proteins that protect cohesion at centromeres during the first meiotic division. Together with other recent findings,2 the study highlighted here has identified Sgo1 as a component that informs the mitotic spindle checkpoint when spindle tension (...) is perturbed. This discovery has provided a molecular link between sister chromatid cohesion and tension‐sensing at the kinetochore–microtubule interface. BioEssays 27:588–591, 2005. © 2005 Wiley Periodicals, Inc.
