Several lines of evidence suggest that children born via Cesarean section are at greater risk for adverse health outcomes including allergies, asthma and obesity. Vaginal seeding is a medical procedure in which infants born by C-section are swabbed immediately after birth with vaginal secretions from the mother. This procedure has been proposed as a way to transfer the mother's vaginal microbiome to the child, thereby restoring the natural exposure that occurs during vaginal birth that is interrupted in the case of (...) babies born via C-section. Preliminary evidence indicates partial restoration of microbes. However, there is insufficient evidence to determine the health benefits of the procedure. Several studies, including trial, are currently underway. At the same time, in the clinic setting, doctors are increasingly being asked to by expectant mothers to have their babies seeded. This article reports on the current research on this procedure and the issues it raises for regulators, researchers, physicians, and patients. (shrink)

Background Following passage of the Patient Self Determination Act in 1990, health care institutions that receive Medicare and Medicaid funding are required to inform patients of their right to make their health care preferences known through execution of a living will and/or to appoint a surrogate-decision maker. We evaluated the impact of external factors and perceived patient preferences on physicians’ decisions to honor or forgo previously established advance directives (ADs). In addition, physician views regarding legal risk, patients’ ability to comprehend (...) complexities involved with their care, and impact of medical costs related to end-of-life care decisions were explored. Methods Attendees of two Mayo Clinic continuing medical education courses were surveyed. Three scenarios based in part on previously court-litigated matters assessed impact of external factors and perceived patient preferences on physician compliance with patient-articulated wishes regarding resuscitation. General questions measured respondents’ perception of legal risk, concerns over patient knowledge of idiosyncrasies involved with their care, and impact medical costs may have on compliance with patient preferences. Responses indicating strength of agreement or disagreement with statements were treated as ordinal data and analyzed using the Cochran Armitage trend test. Results Three hundred eighty-eight of 951 surveys were completed (41% response rate). Eighty percent reported they were likely to honor a patient’s AD despite its 5 year age. Fewer than half (41%) would honor the AD of a patient in ventricular fibrillation who had expressed a desire to “pass away in peace.” Few (17%) would forgo an AD following a family’s request for continued resuscitative treatment. A majority (52%) considered risk of liability to be lower when maintaining someone alive against their wishes than mistakenly failing to provide resuscitative efforts. A large percentage (74%) disagreed that patients could not appreciate complexities surrounding their care while 69% agreed that costs should never impact a physician’s decision as to whether to comply with a patient’s AD. Conclusions Our findings highlight the impact, albeit small, external factors have on physician AD compliance. Most respondents based their decision on the clinical situation at hand and interpretation of the patient’s initial wishes and preferences expressed by the AD. (shrink)

This handbook brings together essays in the philosophy of film and motion pictures from authorities across the spectrum. It boasts contributions from philosophers and film theorists alike, with many essays employing pluralist approaches to this interdisciplinary subject. Core areas treated include film ontology, film structure, psychology, authorship, narrative, and viewer emotion. Emerging areas of interest, including virtual reality, video games, and nonfictional and autobiographical film also have dedicated chapters. Other areas of focus include the film medium’s intersection with contemporary social (...) issues, film’s kinship to other art forms, and the influence of historically seminal schools of thought in the philosophy of film. Of emphasis in many of the essays is the relationship and overlap of analytic and continental perspectives in this subject. (shrink)

Discourses often uncover underlying social boundaries related to concepts such as ethnicity, gender and religion. By applying an intersectional approach, this article shows how the gendering of ethno-religious boundaries is central in the narratives of parents of Belgian, Italian and Moroccan origin, living in Flanders, Belgium. These processes are extremely salient when discourses on partner choice are discussed, as is the focal point in the current study. The construction of boundaries and identities are deeply influenced by dominant social representations. The (...) results show how the construction and justification of boundaries can also have restrictive consequences for individuals. Parents want to restrict daughters for their own good, and exogamy seems to be the prerogative of sons. (shrink)

One problem of interpreting research on subconscious processing is the possibility that participants are weakly conscious of the stimuli. Here, we compared the fMRI BOLD response in healthy adults to clearly visible single letters with the response to letters presented in the absence of any behavioural evidence of visibility . No letter catch trials served as a control condition. Forced-choice responses did not differ from chance when letter-to-background contrast was low, whereas they were almost 100% correct when contrast was high. (...) A comparison of fMRI BOLD signals for supraliminal and subliminal letters with the control trials revealed a signal increase in left BA 37 . Comparison of supraliminal with subliminal letters showed a significant increase in the right inferior frontal gyrus . Finally, a comparison of subliminal with supraliminal letters showed increases in the left middle temporal gyrus and the right extrastriate cortex. (shrink)

The article sets out to develop the concept of attention as a key aspect to building the possible therapeutics that Bernard Stiegler’s recent works have pointed to (The Automatic Society, 2016, The Neganthropocene, 2018 and Qu’appelle-t-on Panser, 2018). The therapeutic aspect of pharmacology takes place through processes that are neganthropic; therefore, which attempt to counteract the entropic nature of digital technologies where there is flattening out to the measurable and the calculable of Big Data. The most obvious examples of this (...) flattening out can be seen in relation to the use of natural language processing technologies for text interpretation and the use of text analytics alongside student analytics. However, the process of exosomatisation of knowledge takes place in forms of hypomnesic tertiary retentions or digital technologies. The loss of knowledge is inherent to these processes of exteriorisation, this loss of knowledge takes place through a process proletarianisation which Marx had pointed to in the Grundisse (1939). The therapeutic gesture is, therefore, an intrinsically educational one, where the loss of knowledge of the pharmacological nature of digital technologies is counteracted by other forms of knowledge construction that can be enabled by digital technologies. Hence, there is a profound educational gesture necessary to enable the re-harnessing of technology to enable the therapeutics. This paper will argue that the positive re-harnessing, the therapeutics, can take place through the development of new forms of neganthropic gestures which can be afforded by the development of specific forms of digital technologies. These also enable a contributive research process whereby the rationalisation of the production of knowledge within the university can be challenged by collaborative, interpretative processes of knowledge production.

IntroductionThis paperback text is an intermediate text and is simply written. As the author himself states, “the book aims to speak to that growing number of interested persons who want to understand more about the study of ethics, ethical issues and the ways ethicists approach them” . The author intends for this book to be an introduction to ethics and uses the first few chapters to swiftly and succinctly provide an introduction to the basics of ethics and the main ethical (...) theories. He then uses later chapters to carry these theories into current ethical realms, such as business, bioethics, environmental, and political and allows the reader to attach the rudimentary ethical theories examined in the earlier chapters to real life issues in order to emphasize the main points. The final section discusses how to internalize ethics and incorporate them into the reader’s daily lives.SummaryFollowing the acknowledgement, he provides a valuable preface piece aptly titled “How t ..

There’s something paradoxical with a person saying ‘I am humble’; it doesn’t seem so humble to self-attribute humility in general, and intellectual humility in particular. In light of the recent interest in educating for intellectual virtues, this paradox has interesting implications to educating for intellectual humility. In particular, one might wonder how a teacher can be a model of intellectual humility to her students. If a teacher says something like ‘Here’s me being an exemplar of intellectual humility’, the paradox above (...) takes on a pedagogical angle. In this paper, I analyze the paradoxes in self-attributing and learning intellectual humility using three different accounts of this virtue, before proceeding to untangle what could be called the ‘Modeling Paradox’ of teaching intellectual humility and figure out whether this virtue can be non-problematically demonstrated to one’s students.

N’a-t-on pas jusqu’à l’excès opposé l’exégèse allégorique d’Alexandrie à l’exégèse historico-littérale des Antiochiens ? Si l’on se réfère au débat des années 50 autour du « sens spirituel » des Écritures, ne peut-on pas penser que l’on a été tenté de le plaquer sur les auteurs anciens, enrôlés pour la circonstance dans l’un ou l’autre camp ? Il vaut donc la peine de rouvrir sans passion le dossier. En réalité, la contestation de l’exégèse spirituelle d’Origène, reprise à l’époque moderne, est (...) fort ancienne : elle se rattache au débat, plus ancien encore, autour de l’allégorie des poèmes homériques et des mythes grecs. Mais précisément le texte biblique peut-il être traité comme les fables des Grecs ? Les exégètes d’Antioche le nient énergiquement. Pourtant, s’ils refusent de faire de l’allégorie une méthode d’exégèse, ils ne renoncent pas, sous certaines conditions, à dépasser la lettre du texte et son sens historique. Ce sens supérieur ou spirituel qu’Origène découvre par l’allégorie – quel que soit du reste le mot qu’il utilise -, les exégètes d’Antioche cherchent à l’atteindre grâce à l’explication dite typologique. Il s’agira donc ici de préciser la frontière entre ces deux modes d’explication.Was not the opposition between the allegorical exegesis of the School of Alexandria and the historic-literary analysis of the School of Antioch pushed to the extreme? If we think back to the 1950s debate about the “spiritual meaning or sense” of the Scriptures, might we not discern there a temptation to project this debate back onto the ancient authors, forced to fit into one camp or the other? It is thus quite worthwhile to open up this file again in a more dispassionate way. In fact, the arguments against Origen’s spiritual exegesis, taken up in modern times, is very old and is connected with the even older debate about the allegorical nature of the Homeric poems and Greek myths. However, is it possible to deal with the Biblical text in the same way as with the Greek fables? The Antioch exegetes denied this vehemently. Still, although they refused to take allegory as a method of exegesis, they did not renounce – in some circumstances – looking beyond the letter of the text and its historical meaning. This superior or spiritual meaning which Origen discovered through allegory – whatever might be the term he utilized – was sought for by the Antioch School through the so-called typological explanation.

1. ‘“But aren't you saying that all that happens is that he moans, and that there is nothing behind it?” I am saying that there is nothing behind the moaning ’ . This passage seems to me to epitomize a conception of the mind and its relation to the body found in the later work of Wittgenstein. It will be convenient to write as if this is his view of the mind. He suggests elsewhere that he is not advancing philosophical (...) theses in his later work; so maybe this view is not a philosophical thesis in some relevant sense; or maybe Wittgenstein is not wholly consistent; or maybe he puts it forward only dialectically, and in other philosophical contexts would have espoused other views of the mind as much as he espouses this one. In any case, what does this one amount to? ‘There is nothing behind the moaning.’ What does this mean? (shrink)

This article analyzes whether Brandom’s ISA (inferential-substitutional-anaphoric) semantics as presented in Making It Explicit (MIE) and Articulating Reasons (AR) can cope with problems resulting from inferentialism’s near-implied meaning holism. Inferentialism and meaning holism entail a radically perspectival conception of content as significance for an individual speaker. Since thereby its basis is fixed as idiolects, holistic inferentialism engenders a communication-problem. Brandom considers the systematic difference in information among individuals as the „point“ of communication and thus doesn’t want to diminish these effects (...) of inferentialism. Instead, explains communication with a model of “navigating among perspectives without sharing contents”. The crucial element in this navigation-model is the functioning of anaphoric connections between tokens uttered in discourse that can be used by every individual speaker in their own perspectival semantic substitution-economies. The heart of Brandom’s semantics is the thesis of the purely inferential, hence non-referential nature of anaphora, coupled with the claim that anaphoric-inferential semantic mechanisms yield sufficient conditions for mutually successful “information-extraction” or interpretation. This article disputes the thesis and denies the claim. Regarding the former it is observed that all of Brandom’s plausible reconstructions of anaphoric discourse-structures rely on covert “reference-infiltrations” that can’t be eliminated. Regarding the latter, a new argument based on context-sensitive semantic phenomena in anaphoric settings shows that the crucial distinction between initiator or anaphoric antecedent and anaphoric dependent cannot be drawn according to Brandom’s own premises without overt and irreducible referential premises. The article concludes that either Brandom’s semantics can offer determinate contents, but then must accept genuinely referential semantic primitives, or else it leaves utterance-contents undeterminable and hence cannot explain communication.

Quine claims that holism (i.e., the Quine-Duhem thesis) prevents us from defining synonymy and analyticity (section 2). In Word and Object, he dismisses a notion of synonymy which works well even if holism is true. The notion goes back to a proposal from Grice and Strawson and runs thus: R and S are synonymous iff for all sentences T we have that the logical conjunction of R and T is stimulus-synonymous to that of S and T. Whereas Grice and Strawson (...) did not attempt to defend this definition, I try to show that it indeed gives us a satisfactory account of synonymy. Contrary to Quine, the notion is tighter than stimulus-synonymy – particularly when applied to sentences with less than critical semantic mass (section 3). Now according to Quine, analyticity could be defined in terms of synonymy, if synonymy were to make sense: A sentence is analytic iff synonymous to self-conditionals. This leads us to the following notion of analyticity: S is analytic iff, for all sentences T, the logical conjunction of S and T is stimulus-synonymous to T; an analytic sentence does not change the semantic mass of any theory to which it may be conjoined (section 4). This notion is tighter than Quine's stimulus-analyticity; unlike stimulus-analyticity, it does not apply to those sentences from the very center of our theories which can be assented to come what may, even though they are not synthetic in the intuitive sense (section 5). Conclusion: We can have well-defined notions of synonymy and analyticity even if we embrace Quine's holism, naturalism, behaviorism, and radical translation. Quine's meaning skepticism is to be repudiated on Quinean grounds. (shrink)

In his critical study of Speusippus Leonardo Tarán (T.) expounds an interpretation of a considerable part of the controversial books M and N of Aristotle's Metaphysics. In this essay I want to consider three aspects of the interpretation, the account of Plato's ‘ideal numbers’ (section I), the account of Speusippus’ mathematical ontology (section II), and the account of the principles of that ontology (section III). T. builds his interpretation squarely on the work of Harold Cherniss (C.), to whom I will (...) also refer. I concentrate on T. because he has brought the ideas in which I am interested together and given them a concise formulation; he is also meticulous in indicating the secondary sources with which he agrees or disagrees, so that anyone interested in pursuing particular points can do so easily by consulting his book.

Background: Magnetic resonance spectroscopic imaging is a neuroimaging technique that may be useful for non-invasive mapping of brain temperature over a large brain volume. To date, intra-subject reproducibility of MRSI-based brain temperature has not been investigated. The objective of this repeated measures MRSI-t study was to establish intra-subject reproducibility and repeatability of brain temperature, as well as typical brain temperature range.Methods: Healthy participants aged 23–46 years were scanned at two time points ~12-weeks apart. Volumetric MRSI data were processed by reconstructing (...) metabolite and water images using parametric spectral analysis. Brain temperature was derived using the frequency difference between water and creatine for 47 regions of interest delineated by the modified Automated Anatomical Labeling atlas. Reproducibility was measured using the coefficient of variation for repeated measures, and repeatability was determined using the standard error of measurement. For each region, the upper and lower bounds of Minimal Detectable Change were established to characterize the typical range of TCRE values.Results: The mean global brain temperature over all subjects was 37.2°C with spatial variations across ROIs. There was a significant main effect for time [F = 37.0, p < 0.0001] and for brain region [F = 2.66, p < 0.0001]. The time*brain region interaction was not significant [F = 0.80, p = 0.83]. Participants' TCRE was stable for each ROI across both time points, with ROIs' COVrep ranging from 0.81 to 3.08% ; majority of ROIs had a COVrep <2.0%.Conclusions: Brain temperature measurements were highly consistent between both time points, indicating high reproducibility and repeatability of MRSI-t. MRSI-t may be a promising diagnostic, prognostic, and therapeutic tool for non-invasively monitoring brain temperature changes in health and disease. However, further studies of healthy participants with larger sample size and numerous repeated acquisitions are imperative for establishing a reference range of typical brain TCRE, as well as the threshold above which TCRE is likely pathological.

Nature seems to be such that we can describe it accurately with quantum theories of bosons and fermions alone, without resort to parastatistics. This has been seen as a deep mystery: paraparticles make perfect physical sense, so why don’t we see them in nature? We consider one potential answer: every paraparticle theory is physically equivalent to some theory of bosons or fermions, making the absence of paraparticles in our theories a matter of convention rather than a mysterious empirical discovery. We (...) argue that this equivalence thesis holds in all physically admissible quantum field theories falling under the domain of the rigorous Doplicher–Haag–Roberts approach to superselection rules. Inadmissible parastatistical theories are ruled out by a locality-inspired principle we call charge recombination. 1 Introduction2 Paraparticles in Quantum Theory3 Theoretical Equivalence3.1 Field systems in algebraic quantum field theory3.2 Equivalence of field systems4 A Brief History of the Equivalence Thesis4.1 The Green decomposition4.2 Klein transformations4.3 The argument of Drühl, Haag, and Roberts4.4 The Doplicher–Roberts reconstruction theorem5 Sharpening the Thesis6 Discussion6.1 Interpretations of Quantum Mechanics6.2 Structuralism and haecceities6.3 Paraquark theories.

BackgroundStory recall tests have shown variable sensitivity to rate of cognitive decline in individuals with Alzheimer’s disease biomarkers. Although SR tasks are typically scored by obtaining a sum of items recalled, item-level analyses may provide additional sensitivity to change and AD processes. Here, we examined the difficulty and discrimination indices of each item from the Logical Memory SR task, and determined if these metrics differed by recall conditions, story version, lexical categories, serial position, and amyloid status.Methodsn = 1,141 participants from (...) the Wisconsin Registry for Alzheimer’s Prevention longitudinal study who had item-level data were included in these analyses, as well as a subset of n = 338 who also had amyloid positron emission tomography imaging. LM data were categorized into four lexical categories, and by serial position. We calculated difficulty and discriminability/memorability by item, category, and serial position and ran separate repeated measures ANOVAs for each recall condition, lexical category, and serial position. For the subset with amyloid imaging, we used a two-sample t-test to examine whether amyloid positive and amyloid negative groups differed in difficulty or discrimination for the same summary metrics.ResultsIn the larger sample, items were more difficult in the delayed recall condition across both story A and story B. Item discrimination was higher at delayed than immediate recall, and proper names had better discrimination than any of the other lexical categories or serial position groups. In the subsample with amyloid PET imaging, proper names were more difficult for Aβ+ than Aβ−; items in the verb and “other” lexical categories and all serial positions from delayed recall were more discriminate for the Aβ+ group compared to the Aβ− group.ConclusionThis study provides empirical evidence that both LM stories are effective at discriminating ability levels and amyloid status, and that individual items vary in difficulty and discrimination by amyloid status, while total scores do not. These results can be informative for the future development of sensitive tasks or composite scores for early detection of cognitive decline. (shrink)

Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption—which caused stimulus components to become inaccessible to rapid search—was an all-or-nothing effect, and so could serve as a powerful test of grouping. It is shown that these effects are unlikely to be due to blurring by simple spatial filters (...) at early visual levels. It is proposed instead that they are due to more sophisticated processes that rapidly bind contour fragments into spatially-extended assemblies. These results support the view that rapid visual search cannot access the primitives formed at the earliest stages of visual processing; rather, it can access only higher-level, more ecologically-relevant structures.

On several current views, including those of Matthew Kieran, Gary Iseminger, Jerrold Levinson, and Noël Carroll, aesthetic appreciation or experience involves second-order awareness of one’s own mental processes. But what if it turns out that we don’t have introspective access to the processes by which our aesthetic responses are produced? I summarize several problems for introspective accounts that emerge from the psychological literature: aesthetic responses are affected by irrelevant conditions; they fail to be affected by relevant conditions; we are ignorant (...) of their causes and thus confabulate in explaining them; our attempts to offer explanations change our preferences; and the preferences we form after explanation are lower in quality. I suggest that by distinguishing introspective awareness of mental processes from introspective awareness of mental states, we can safeguard a worthwhile concept of aesthetic experience. In addition, we should recognize that theoretical, rather than introspective, understanding of our mental processes may play a valuable role in aesthetic appreciation. (shrink)

John Corcoran and George Boger. Aristotelian logic and Euclidean geometry. Bulletin of Symbolic Logic. 20 (2014) 131. -/- By an Aristotelian logic we mean any system of direct and indirect deductions, chains of reasoning linking conclusions to premises—complete syllogisms, to use Aristotle’s phrase—1) intended to show that their conclusions follow logically from their respective premises and 2) resembling those in Aristotle’s Prior Analytics. Such systems presuppose existence of cases where it is not obvious that the conclusion follows from the premises: (...) there must be something deductions can show. Corcoran calls a proposition that follows from given premises a hidden consequence of those premises if it is not obvious that the proposition follows from those premises. By a Euclidean geometry we mean an extended discourse beginning with basic premises—axioms, postulates, definitions—1) treating a universe of geometrical figures and 2) resembling Euclid’s Elements. There were Euclidean geometries before Euclid (fl. 300 BCE), even before Aristotle (384–322 BCE). Bochenski, Lukasiewicz, Patzig and others never new this or if they did they found it inconvenient to mention. Euclid shows no awareness of Aristotle. It is obvious today—as it should have been obvious in Euclid’s time, if anyone knew both—that Aristotle’s logic was insufficient for Euclid’s geometry: few if any geometrical theorems can be deduced from Euclid’s premises by means of Aristotle’s deductions. Aristotle’s writings don’t say whether his logic is sufficient for Euclidean geometry. But, there is not even one fully-presented example. However, Aristotle’s writings do make clear that he endorsed the goal of a sufficient system. Nevertheless, incredible as this is today, many logicians after Aristotle claimed that Aristotelian logics are sufficient for Euclidean geometries. This paper reviews and analyses such claims by Mill, Boole, De Morgan, Russell, Poincaré, and others. It also examines early contrary statements by Hintikka, Mueller, Smith, and others. Special attention is given to the argumentations pro or con and especially to their logical, epistemic, and ontological presuppositions. What methodology is necessary or sufficient to show that a given logic is adequate or inadequate to serve as the underlying logi of a given science. (shrink)
