Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

Idiopathic generalized epilepsy (IGE) is a common type of epilepsy and despite an increase in the number of available anti-seizure medications, approximately 20–30% of people with IGE continue to experience seizures despite adequate medication trials. Unlike focal epilepsy, resective surgery is not a viable treatment option for IGE; however, neuromodulation may be an effective surgical treatment for people with IGE. Thalamic stimulation through deep brain stimulation (DBS) and responsive neurostimulation (RNS) have been explored for the treatment of generalized and focal (...) epilepsies. Although the data regarding DBS and RNS in IGE is limited to case reports and case series, the results of the published studies have been promising. The current manuscript will review the published literature of DBS and RNS within the centromedian nucleus of the thalamus for the treatment of IGE, as well as highlight an illustrative case.

This book brings together an international group of scholars to discuss the ramifications of Heidegger's Black Notebooks for philosophy and the humanities. In contrast to both those who seek to exonerate Heidegger and those who simply condemn him, they urge careful reading and rereading of his work to turn Heideggerian thought against itself.

This study examines how heightened expectations of board responsibility and accountability affect the socio-cognitive decision-making of boards and their collective task performance. Using data from the directors of 60 boards who served before and after the enactment of Sarbanes–Oxley, this study provides insight into the potential negative impact that this tightened accountability environment can have on a board’s task performance. Examining several socio-cognitive elements of board decision-making, board authority is found to have a positive main effect on board task performance, (...) while relative CEO power and affective conflict have curvilinear relationships with board task performance. Cohesiveness also moderates the relationship between a board’s perceived uncertainty and affective conflict with board task performance. In sum, the model shows how a new era of director accountability can affect the social cognitions of board decision-making that underlie board task performance. (shrink)

Ushenko presented his philosophy of logic in vehement opposition to "the postulationist theory." In the endeavor to amputate logic from philosophy and absorb it within mathematics, the postulationists viewed logic as an isolated object-logic to be discussed in meta-logic and construed its symbolic formulas as a game played according to arbitrarily established rules. The objections Ushenko raised are no longer novel, but twenty years ago the entire controversy was new. Above all, he stressed the numerous difficulties entangling the meta-logic. He (...) scored the menace of an infinite regress of meta-logics, and insisted that the consequences of Gödel's work necessarily frustrate the initial great expectations of the postulationists. No purely formal system can be internally proved to be self-consistent and certainly no formal language can ever become as comprehensive as English, though the price of such comprehensiveness is the inevitable occurrence of contradictory sentences. Moreover, he argued that, despite the postulationists' pretense that rules like the principle of non-contradiction were mere conventions for playing the game of logic, these rules proved ubiquitous by trespassing from the object-logic and intruding into the ultimate reaches of the meta-logic.

Some philosophers contend that to effectively address problems such our global environmental crisis, humans must collectively embrace a polyphonic, environmentalist grand narrative, very different from the narratives accepted by modernists. Cultural theorists who write about metamodernism likewise discuss the recent return to a belief in narratives, and contend that our society’s current approach to narratives is very different from that of the modernists. In this paper, I articulate these philosophers’ and cultural theorists’ positions, and I highlight and explore interconnections between (...) them. Additionally, I argue that if the authors I discuss are correct, then we morally ought to embrace a metamodernist, polyphonic, environmentalist grand narrative, in order to effectively address an array of global crises. Such a grand narrative is a necessary ingredient of an adequate global ethics. (shrink)

Ethical deliberations are unfolding for potentially controversial organoid‐entities such as brain organoids and embryoids. Much of the ethical deliberation centers on the questionable moral status of such organoid‐entities. However, while such work is important and appropriate, ethical deliberations may become too exclusively rooted in moral status and potentially overshadow other relevant moral dilemmas. The ethical discussion on organoid models can benefit from insights brought forth by both Judith Jarvis Thomson and Don Marquis in how they attempted to advance the abortion (...) debate. To discuss other abortion ethical issues more fully, both Thomson and Marquis assumed differing moral status positions of the conceptus and followed lines of reasoning based on these moral status assumptions. We suggest a similar approach with controversial organoid‐entities like brain organoids and embryoids. To avoid overshadowing or overlooking other relevant ethical issues, ethicists ought to first assume an organoid‐entity moral status position (such as a high moral status or no moral status) and explore any possible arguments that may result from such a position. While we ought not to copy the content of Thomson and Marquis' arguments exactly for organoid‐entities, it is worthwhile to translate their arguments' overarching structures. This paper explores the relevant insights of Thomson and Marquis, how they can be translated into the organoid ethics debate, and what possible lines of inquiry may be worth exploring based on particular moral status assumptions.

While the Bhagavad Gītā is an acknowledged treasure of world spiritual literature, few people know a parallel text, the Īśvara Gītā. This lesser-known work is also dedicated to a god, but in this case it is Śiva, rather than Kṛṣṇa, who is depicted as the omniscient creator of the world. Andrew J. Nicholson’s Lord Śiva’s Song makes this text available in English in an accessible new translation. A work of both poetry and philosophy, the Īśvara Gītā builds on the (...) insights of Patañjali’s Yoga Sūtra and foreshadows later developments in tantric yoga. It deals with the pluralistic religious environment of early medieval India through an exploration of the relationship between the gods Śiva and Viṣṇu. The work condemns sectarianism and violence and provides a strategy for accommodating conflicting religious claims in its own day and in our own. (shrink)

In his A Defense of Abortion David Boonin largely misreads one of the oldest and most defensible arguments against abortion, the argument based on the fetus’s rational nature. In this paper it will be shown that Boonin’s characterization of this argument isinaccurate, that his criticisms of it are therefore ineffective, and that his own criterion—the possession of a “present, dispositional, ideal desire for a future like ours”—is insufficient to ground a human being’s right to life. Boonin’s misread of this classic (...) argument is largelythe result of his focus upon the “properties,” as opposed to the nature, of a fetus and his failure to consider the notion of a rational nature as ordered to rational activities. In addition, his argument for abortion rights fails on its own terms because it ultimately licensesinfanticide. Infants have desires and they possess a future like ours, but they do not have any desire for a future like ours. (shrink)

In this paper, I revisit and evaluate Kant’s prerequisites for “perpetual peace,” including the claim, central to contemporary political rhetoric, that formal democracy produces peace. I argue that formal democracy alone is insufficient to address the kinds of deep-rooted structural violence that ultimately manifest interrorism and other forms of direct violence. I claim that the attempt to eliminate structural violence, and so achieve real “perpetual peace,” requires a moresubstantive sort of democracy, of which the United States and the West remain (...) poor examples. It requires a political critique that goes deeper than just thecritique of state power and government action. This paper tries to develop that critique through a conception of structural violence, and of participatory parity asan overarching standard of redress for this type of violence in all of its forms.

This essay argues, drawing from both philosophical and scientific work on disgust, that since disgust is a universal human emotion with roots in evolutionary adaptation, and since capitalism inevitably produces disgusting food, a critique of capitalism based upon the category of disgust and centered on the food system may be more practically effective than traditional critiques of capitalism. This critique forms the basis of what I call a critical theory of food.

We investigated, experimentally, the contention that the folk view, or naïve theory, of time, amongst the population we investigated is dynamical. We found that amongst that population, ~ 70% have an extant theory of time that is more similar to a dynamical than a non-dynamical theory, and ~ 70% of those who deploy a naïve theory of time deploy a naïve theory that is more similar to a dynamical than a non-dynamical theory. Interestingly, while we found stable results across our (...) two experiments regarding the percentage of participants that have a dynamical or non-dynamical extant theory of time, we did not find such stability regarding which particular dynamical or non-dynamical theory of time they take to be most similar to our world. This suggests that there might be two extant theories in the population—a broadly dynamical one and a broadly non-dynamical one—but that those theories are sufficiently incomplete that participants do not stably choose the same dynamical theory as being most similar to our world. This suggests that while appeals to the ordinary view of time may do some work in the context of adjudicating disputes between dynamists and non-dynamists, they likely cannot do any such work adjudicating disputes between particular brands of dynamism.

I argue that sometimes a group can author a work of art without the work being either co-authored or multiply-authored. Sometimes the group, itself, is an author, rather than any of its members alone or together. I argue that when a group is an author like this, it has mental properties that no individual member of the group possesses. For example, we can consider the groups that authored digital remixes based on a film titled #INTRODUCTIONS created by the artists LaBeouf, (...) Rönkkö & Turner. YouTubers posted their digital remixes online, and the question is: Who authored those remixes? I contend that many digital remixes are authored by groups that are capable of cognition. (shrink)

Amyloid β peptide (βA4) accumulates as plaques in the brains of individuals with Alzheimer's disease and Down's syndrome, and may contribute to the cognitive decline that is a feature of these diseases. βA4 is a normal product of cell metabolism, derived from the amyloid precursor protein (APP), but the biological functions of these molecules are not fully known. A hypothetical, descriptive model of the biological interrelationships between βA4 and APP is presented. APPS, the soluble form of APP, which is released (...) at the neuronal surface, and βA4 are envisaged as physiological ligands which have reciprocal paracrine effects on neuronal growth and neurite extension. Differential expression of these factors, manifest as changes in the APPS:βA4 ratio, may therefore have growth‐promoting or growth‐inhibiting effects on neurons. These effects may be mediated through separate cell‐surface interactions but common intracellular effector systems, such as calcium and protein kinase C. In turn, the intracellular events may control the relative production of each ligand from APP through negative feedback loops. Disturbances of these control mechanisms may permit pathological overproduction, and hence accumulation, of βA4. Such a model may also have therapeutic implications. (shrink)

This article explains how data associated with attitude change and persuasion in mainstream psychology and social psychology can be reinterpreted as evidence of the agentive ability of taking a position. A critical review is made of the elaboration likelihood model and a position model is adapted from positioning theory. The postulates of the elaboration likelihood model are then subjected to critical scrutiny by means of comparison with our position model. In this way regularities associated with attitude change and persuasion are (...) interpreted as evidence of a deliberative process, involving negotiation and the use of supporting and opposing arguments. We present this as evidence of the commonly held agentive ability to position oneself and anticipate the positions of others. (shrink)

In the conclusion to a most critical essay spanning nearly thirty pages of unrelieved polemic, Ernest Nagel has commented that Blanshard’s “vision … of the scope, and office of human reason is not without grandeur and inspiring power, and its insistence on system and rational order reveals its sources in human aspirations.” The grandeur of Blanshard’s vision of sovereign reason and its roots in human aspirations may be glimpsed, along with its difficulty, by a brief survey of his philosophy.

John Cage and Henry David Thoreau draw attention to the indeterminacy of wild nature and imply humans cannot entirely control the natural world. This paper argues Cage and Thoreau each encourages his audience to recognize their own human limitations in relation to wildness, and thus each helps his audience to develop greater humility before nature. By reflecting on how Thoreau’s theory relates to Cage’s music, we can recognize how Cage’s music contributes to audiences’ environmental moral education. We can appreciate the (...) role of music in helping audiences to develop values conducive to environmentally sustainable practices. (shrink)

Adorno’s critical theory aims to open space for the expression of alternative futures, but its insistence on dialectical reflection encourages at the same time our sustained attentiveness to the psychic and material constraints that may prevent the very possibilities we imagine. In this article, I argue that dialectical reflection signals a location at which transcendental claims enter our thinking and that, for Adorno, such reflection provides a locus for a critically animating interplay between rhetorical figurations of darkness and redemption, or (...) material constraint and alternative possibility. Concerned less with the substance of Adorno’s criticisms than with how his dialectical mode of thinking can be said to shape critical reflection as such, I suggest that Adorno provides a model orientation for democratic engagement in our time and a sobering critical supplement to recent Derridean discourse on radical democracy.

Davey has failed to clarify the critical evidence that could corroborate the expectancy bias hypothesis and refute preparedness theory. Such a clarification is necessary because each theory could potentially allow for multiple distal and proximal influences on selective associations. Expectancies are not the only proximal mediators. Our recent findings indicate that affective response matching may be an additional factor promoting such associations.

Del Giudice provides an extension of the life history theory of attachment that incorporates emerging data suggestive of sex differences in avoidant male and preoccupied female attachment patterns emerging in middle childhood. This commentary considers the place of disorganized attachment within this theory and why male children may be more prone to disorganized attachment by drawing on Trivers's parental investment theory.

Murayama and Jach offer a thoughtful and timely critique of motivation constructs. We largely concur with their basic premises, but offer additional input and clarification regarding the importance of carefully considering the energization and direction components of motivation, and fully attending to the hierarchical aspect of motivation rather than prioritizing particular levels of analysis.

About one-third of Australians use the services of complementary and alternative medicine (CAM); but debate about the role of CAM in public healthcare is vociferous. Despite this, the mechanisms driving CAM healthcare choices are not well understood, especially in rural Australia. From 2016 to 2018, 2,679 persons from the Goulburn Valley, northern Victoria, were surveyed, 28% (755) of whom reporting visiting CAM practitioners. A Generalized Linear Mixed Model was used to assess associations between various socio-demographic variables and the use of (...) CAM services. The strongest significant inverse (p < 0.05) association with CAM use overall was being unemployed, with markedly lower odds of using CAM than those employed full-time (OR 0.22 [0.12, 0.41]). The next strongest inverse relationship was being retired (OR 0.44 [0.30, 0.65]). The strongest positive associations were with English spoken at home (OR 2.38 [1.34, 4.24]), private health insurance (hospital cover) (1.57 [1.28, 1.91]), being Australian born (OR 1.61 [1.14, 2.28]), and female sex (1.25 [1.02, 1.52])). Females had significantly higher odds of using osteopathy than males (OR 1.98 [1.33, 2.96]) but there were no significant sex differences for chiropractic or massage. This is the first such study conducted solely for a rural Australian population. The drivers of CAM use differed from previous nation-wide studies and they varied across modalities. The factors identified here as being associated with CAM use could be used by CAM practitioners in developing person-centred services. Similarly, the findings are relevant to primary-care services in understanding what sectors of society might eschew conventional health care for CAM in rural regions, where health services are often limited.

Empirical work has lately confirmed what many philosophers have taken to be true: people are ‘biased toward the future’. All else being equal, we usually prefer to have positive experiences in the future, and negative experiences in the past. According to one hypothesis, the temporal metaphysics hypothesis, future-bias is explained either by our beliefs about temporal metaphysics—the temporal belief hypothesis—or alternatively by our temporal phenomenology—the temporal phenomenology hypothesis. We empirically investigate a particular version of the temporal belief hypothesis according to (...) which future-bias is explained by the belief that time robustly passes. Our results do not match the apparent predictions of this hypothesis, and so provide evidence against it. But we also find that people give more future-biased responses when asked to simulate a belief in robust passage. We take this to suggest that the phenomenology that attends simulation of that belief may be partially responsible for future-bias, and we examine the implications of these results for debates about the rationality of future-bias.
