Transcranial magnetic stimulation (TMS) of the visual cortex can induce phosphenes as can non-diagnostic ultrasound, the latter while participants have closed their eyes during Stimulation. Here we sought to study potential alteration of a visual target (a white crosshair) due to application of diagnostic ultrasound to the visual cortex. We applied a randomized series of actual or sham diagnostic ultrasound to the visual cortex of healthy participants while they stared at a visual target, with the ultrasound device placed where TMS (...) elicited phosphenes. These participants observed percepts 7 out of 10 times, consisting of extra or extensions of lines relative to the original crosshair, and additional colors. Observation of a percept occurred an average of 53.7 +/- 2.6% of the time over the course of the experiment for these participants. In contrast, 7 out of 10 participants exposed to sham-only diagnostic ultrasound observed comparable percepts an average of 36.3 +/ 1.9% of the time, a statistically significant difference (p < 0.00001). Moreover, on average, participants exposed to a combination of sham and actual ultrasound reported a net increase of 47.9 percentage points in the likelihood that they would report a visual effect by the end of the experiment. Our experiment demonstrated that a random combination of sham-only and actual diagnostic ultrasound applied to the visual cortex of participants increased the likelihood that they would observe visual effects, but not the type of effects, with that likelihood increasing over the course of the experiment. From this we conclude that repeated exposures by diagnostic ultrasound made the visual cortex more responsive to stimulation of their visual cortex by the visual target. These observations, consistent with other’s observation of effects of diagnostic ultrasound stimulation of human motor cortex and amygdala, as well as the FDA approved nature of diagnostic ultrasound, may lead to increased study of diagnostic ultrasound applied to human brain.

On the most popular account of material constitution, it is common for a material object to coincide precisely with one or more other material objects, ones that are composed of just the same matter but differ from it in sort. I argue that there is nothing that could ground the alleged difference in sort and that the account must be rejected.

I aim to show that there are cases in which an ordinary material object exists intermittently. Afterwards there are a few words about the consequences of acknowledging such cases, but what is of more interest is the route by which the conclusion is reached. When deciding among competing descriptions of the cases considered, I have tried to reduce to a minimum the role of intuitive judgment, and I have based several arguments on "metaphysical principles," two of which I have defended.

The book is divided into 3 parts. The first argues that activities which appear to be timeless - gathering knowledge, analysing, disseminating and employing it - are in fact time-bound and take different forms in different periods and places. The second part tries to counter the tendency to write a triumphalist history of the 'growth' of knowledge by discussing losses of knowledge and the price of specialization. The third part offers geographical, sociological and chronological overviews, contrasting the experience of centres (...) and peripheries and arguing that each of the main trends of the period - professionalization, secularization, nationalization, democratization, etc, coexisted and interacted with its opposite."--Publisher.

This essay discusses the use of analogies drawn from the Holocaust in cultural representations and critical scholarship on dementia. The paper starts with a discussion of references to the death camp in cultural narratives about dementia, specifically Annie Ernaux’s account of her mother’s dementia in I Remain in Darkness. It goes on to develop a critique of Italian philosopher Giorgio Agamben’s work on biopolitics and “bare life,” focusing specifically on the linguistic foundations of his thinking. This underpins a consideration of (...) the limitations of his philosophy and ontologically derived notions of weakness and passivity in imagining life with dementia as a potential site of agency or as the locus for transformative ideas about care, community, and non-instrumentalist conceptions of human value.

An argumentative passage that might appear to be an instance of denying the antecedent will generally admit of an alternative interpretation, one on which the conditional contained by the passage is a preface to the argument rather than a premise of it. On this interpretation. which generally is a more charitable one, the conditional plays a certain dialectical role and, in some cases, a rhetorical role as well. Assuming only a very weak principle of exigetical charity, I consider what it (...) would take to justify the less charitable interpretation. I then present evidence that those conditions are seldom met. Indeed, I was unable to find a single published argument that can justifiably be charged with denying the antecedent. (shrink)

Throughout the developing world, it is a well-documented fact that women farmers tend to get lower yields than their male counterparts. Typically this is attributed to disproportionate access to high-quality inputs and labor, with some even arguing there could be a skills-gap stemming from unbalanced access to training and education. This article examines the gender-based yield gap in the context of Zambian maize producers. In addition to the usual drivers, we argue that Zambia’s patriarchal and multi-tiered land distribution system could (...) disfavor women with respect to accessing quality soils. We are uniquely able to control for soil characteristics using farm data from a sample of 1573 fields with accompanying soil analysis. We find an expected difference in yields, but no evidence of a gap in unobserved characteristics, like skill, after controlling for access to inputs, especially quality soil, suggesting women are indeed disproportionately disadvantaged. We discuss how our findings could be used to develop self-targeting policy interventions that could empower women and would be consistent with the government’s stated equity goals. (shrink)

This article suggests that Simone de Beauvoir's The Second Sex offers an important contribution to a feminist phenomenology of temporality. In contrast to readings of The Second Sex that focus on the notion of “becoming” as the main claim about the relation between “woman” and time, this article suggests that Beauvoir's discussion of temporality in volume II of The Second Sex shows that Beauvoir understands the temporality of waiting, or a passive present, to be an underlying structure of women's existence (...) and subordination. Accordingly, I argue that Beauvoir does not see “woman” as a mere becoming, as that which unfolds in time, but instead understands becoming a woman to be realized as lived time. As such, Beauvoir's account shows that gender and temporality are deeply entangled, and thus she challenges the classic phenomenological account of temporality as a general, given structure of human existence. More specifically, I argue that her account shows how a particular experience of time is an underlying structure of sexual objectification, a claim that expands on the feminist phenomenological claim that a particular relation to space becomes a way in which women take up and negotiate their own subordination and objectification.

There is a long history, dating back to the 50s, which examines the manner in which team roles contribute to effective team performance. However, much of this work has been built on ad-hoc teams working together for short periods of time under conditions of minimal stress. Additionally, research has been conducted with little attention paid to the importance of temporal factors, despite repeated calls for the importance of considering time in team research (e.g., Mohammed, Hamilton, & Lim, 2009). To begin (...) to understand team roles and how temporal aspects may impact the types of team roles employed when teams are working in extreme mission critical environments, the current manuscript uses a data-driven, bottom-up approach. Specifically, we employ the use of retrospective historical data as our input and a historiometric approach (Simonton, 2003). Source documents consist primarily of autobiographies, memoires, biographies, and first-hand accounts of crew interaction during spaceflight. Critical incidents regarding team interaction were extracted from these source documents and independently coded for team roles by two trained raters. Results of the study speak to the importance of task and social roles within teams that are predominantly intact and operating in extreme environments where mistakes can be life threatening. Evidence for the following task (i.e., coordinator, boundary spanner, team leader, evaluator, critic, information provider, team player, and innovator) and social roles (i.e., team builder, nurturer, harmonizer, entertainer, jokester, and the negative roles of attention seeker and negativist) were found. While it is often task roles that receive the greatest attention, results point to the importance of not neglecting the socioemotional health of the team (and the corresponding roles). Results also indicated that while some roles were consistently enacted independent of temporal considerations (e.g., mission length), the degree to which others were enacted varied across missions of differing lengths. Additionally, based on the current sample we see the following trends: (1) increased enactment of the team builder role as mission duration increases, (2) prominence of the entertainer role, and (3) increased emphasis on the visionary/problem solver role on missions over two years.

This eloquent 1757 treatise examines how interactions with the physical world affect formulation of ideals related to beauty and art. Tremendously influential on the development of aesthetic theory, this formative dissertation was among the first explorations of the concept of the sublime and remains a thought-provoking study for modern readers.

The paper formulates and defends a version of the Identity of Indiscernibles and demonstrates that it entails a non-trivial version of the doctrine of essentialism.

This paper1 uses concepts of anxiety and Foucauldian governmentality to investigate the ways that the discourses supporting the ban on performance-enhancing drugs in sport have been manipulated and broadened to treat this issue as a public policy and health issue rather than an example of rule violation in sport. Some effects of this expansion include the broadening of drug testing to include testing for recreational drugs, the intrusion of both central governments and scientific experts into the issue and the curtailment (...) of civil liberties for athletes. A further effect has been the perpetration of injustices against athletes under the guise of such injustices being necessary to maintain the integrity of sport. (shrink)

This paper compares Dewey's and Russell's views of "immediate knowledge." Dewey was perhaps mistaken in attributing to Russell the view that immediate sense data provide incorrigible foundations for knowledge. Russell's characterization of sensing plus attention as the most immediate knowing of which we have experience nevertheless remains a valid target of Dewey's criticisms. These two philosophers developed very different theories of logic and knowledge, language and experience. Given the reconstructed notions of experience and knowledge at the root of Dewey's logical (...) theory, referring to knowledge as immediate or nearly immediate constitutes a serious category mistake.

ABSTRACT This article offers an account of cis sense in order to draw attention to the relation between meaning-making and cisnormativity. By drawing on Merleau-Ponty’s notion of institution and phenomenological considerations of habit, it is argued that cis sense is a mode of perception that institutes and sediments an individual and social habit of the third-person conferral of gender that occludes gender variance and creates the social conditions necessary for transphobia. This consideration of cis sense challenges the mainstream conception of (...) cis as an identity category, highlighting instead that it is a habitual disposition, and gestures to the significance of trans sense as an alternative institution of gendered meaning.

This study empirically investigates the dismissal of U.S. CEOs following negative media coverage of environmental, social, and governance (ESG) practices. Extending related literature on the media, ESG, and CEO dismissal, I develop a theoretical framework that considers the media as an influential third party that forms and reflects public opinion about ESG issues. In this role, the media reduces information asymmetry by providing cues on their relative salience and prompting corporate directors to attribute firm-level ESG issues to the CEO, regardless (...) of their involvement in the misconduct. Findings confirm this framework and particularly suggest that coverage of issues in prominent media sources is more likely to result in CEO dismissal. Further, companies that have made public commitments to ESG oversight and those with stronger monitoring are more likely to dismiss the CEO following negative coverage of ESG issues. Overall, this study builds an understanding of how contemporary boards approach the uncertain CEO dismissal decision amidst media coverage of ESG- related misconduct and reflects a shifting norm towards ESG integration at the board-level.

Logic for Dewey is a normative inquiry into the nature of inquiry itself. Goodman’s grue example is assessed in light of Dewey's vocabulary for logic as presented in his 1938 Logic.

To what extent does the fact that a philosopher, in order to communicate, is constrained to use the same language and the same concepts as other members of his society, inhibit him from developing genuinely original modes of thought? Section I of this paper outlines arguments for the view that any attempt at radical originality, of the kinds traditionally expected of philosophy, must involve misuse of these shared concepts. Section II, however, on the basis of an examination of what it (...) is for different members of a society to use the same concepts, argues that so doing does not rule out important differences over instantiations and logical interrelations. It then attempts to show that this latitude for difference is adequate to allow for certain kinds of philosophical originality, for example, that shown in the Whiteheadian philosophy of organism.

Psychologists are interested in understanding how early social environments impact children’s behavior and cognition. Early social environments are comprised of social relationships; however, there have been relatively few tools available to quantify the depth and breadth of children’s social relationships. We harnessed the power of social networks to demonstrate that networks can be used to describe children’s early social environments. Descriptive data from American children aged 6 months–5 years demonstrates that network properties can be used to provide a quantitative analysis (...) of children’s early social environments and highlights how these environments vary across development. Social network methodology will provide researchers with a comprehensive picture of children’s early social experiences and improve studies exploring individual differences. (shrink)
