We show that, given extensive exploration of a three-dimensional volume, grid units can form with the approximate periodicity of a face-centered cubic crystal, as the spontaneous product of a self-organizing process at the single unit level, driven solely by firing rate adaptation.

Older adults often have long-term relationships, and many of their goals are intertwined with their respective partners. Joint goals can help or hinder goal progress. Little is known about how accurately older adults assess if a goal is joint, the role of over-reporting in these perceptions, and how joint goals and over-reporting may relate to older partners' relationship satisfaction and physical health. Two-hundred-thirty-six older adults from 118 couples listed their three most important goals and whether they thought of them as (...) goals they had in common with and wanted to achieve together with their partner. Two independent raters classified goals as “joint” if both partners independently listed open-ended goals of the same content. Goal progress and relationship satisfaction were assessed 1 week later. Allostatic load was calculated using nine different biomarkers. Results show that 85% self-reported at least one goal as joint. Over-reporting– the perception that a goal was joint when in fact it was not mentioned among the three most salient goals of the spouse – occurred in one-third of all goals. Multilevel models indicate that the number of externally-rated joint goals was related to greater goal progress and lower allostatic load, but only for adults with little over-reporting. More joint goals and higher over-reporting were each linked with more relationship satisfaction. In conclusion, joint goals are associated with goal progress, relationship satisfaction, and health, but the association is dependent on the domain of functioning. (shrink)

BackgroundExercise is primarily sustained by energy derived from lipids, and glucose. Substrate utilization is the pattern by which these fuel sources are used during activity. There are many factors that influence substrate utilization. We aim to delineate the effect of exercise intensity and body composition on substrate utilization.ObjectiveThe objective of our study was to discern the differences in substrate utilization profiles during a maximal and submaximal graded exercise test, and to determine the extent to which body composition influences substrate utilization (...) during the exercise tests.MethodsA total of 27 male athletes, 32.5 ± 11 years of age, were recruited for this study. Body composition was analyzed using a bioelectrical impedance analyzer. Maximal and submaximal exercise tests were performed on a treadmill. A novel graded submaximal treadmill protocol was used for the submaximal test.ResultsAverage percent body fat was 15.8 ± 5%. Average maximal oxygen consumption was 47.6 ± 9 mL/kg/min, while the average exercise intensity at which participants were shifting to glucose predominance for energy during the maximal and submaximal tests were 76 ± 8.3% and 58.4 ± 21.1%, respectively. A paired-samples t-test was conducted to compare percent VO2max at crossover point in maximal and submaximal graded exercise tests. There was a significant difference in percent VO2max at the crossover point for maximal and submaximal tests. A linear regression was performed to elucidate the interaction between exercise intensity at the crossover point and body composition during a maximal and submaximal graded exercise test. There was a significant effect of PBF on percent VO2max at crossover point during the maximal graded exercise test [F = 9.10, P = 0.006] with an R2 of 0.245. However, there was no significant effect of PBF on percent VO2max at crossover point during the submaximal graded exercise test.ConclusionSubstrate utilization, represented by the crossover point, is dependent on the rate of increase in exercise intensity. At maximal efforts, the crossover to carbohydrates from fats as the predominant fuel source occurs at a significantly later stage of percent VO2max than at submaximal efforts. Furthermore, body composition represented by PBF is a significant predictor of substrate utilization during maximal efforts. Athletes with a relatively higher PBF are more likely to have increased lipid oxidation during high intensity exercises than those with a lower body fat percentage. (shrink)

In the past half‐century critical historiographies of philosophy have challenged the exclusionist Eurocentric and masculinist presumptions of “history of philosophy,” and we have witnessed the multiplication of philosophical worlds in the relation of indigenous to Western scholarship and in critical philosophical anthropologies. Does this mean that there is, or can be, no unity to the history of philosophy? In this article, I argue that these challenges are not incompatible with our thinking the unity of the history of philosophy, so long (...) as we understand it to be an historical “distributive unity,” constitutively related to other histories and to social, political, and institutional realities, and open to continuous transformation. The idea of a “critical history of philosophy” emerges from this. I argue that a critical history of philosophy proceeds via the problematizations of contemporary thought, which are then themselves challenged by that critical history and that it can and must include what remains marginal to its canonical history, working in conjunction with the theory and practices of other disciplines. These general claims are illustrated by showing how a critical history of philosophy could proceed in practice in relation to the contemporary problematization of the concept of “sex.”. (shrink)

IntroductionConcussion is a growing public health concern. No uniformly established therapy exists; neurofeedback studies report treatment value. We use infralow frequency neuromodulation to remediate disabling neurological symptoms caused by traumatic brain injury and noted improved outcomes with a novel concussion protocol. Postconcussion symptoms and persistent postconcussion symptoms are designated timelines for protracted neurological complaints following TBI. We performed a retrospective study to explore effectiveness of ILF in PCS/PPCS and investigated the value of using this concussion protocol.MethodPatients with PCS/PPCS seen for (...) their first neurology office visit or received their first neurofeedback session between 1 August 2018 and 31 January 2021 were entered. Outcomes were compared following treatment as usual vs. TAU with ILF neurotherapy. The study cohort was limited to PPCS patients; the TAU+ILF group was restricted further to PPCS patients receiving at least 10 neurotherapy sessions. Within the TAU+ILF group, comparisons were made between those who trained at least 10 sessions using concussion protocol and those who trained for at least 10 sessions of ILF regardless of protocol.ResultsAmong our resultant PPCS cohort leading persistent neurological complaints were headache, memory impairment, and brain fog. PPCS patients in TAU+ILF+CP demonstrated greater net and percent improvement of symptoms compared to PPCS subjects in TAU. PPCS patients in TAU+ILF-CP trended toward significant symptom improvements compared to TAU, and TAU+ILF+CP trended toward greater efficacy than TAU+ILF-CP.ConclusionPPCS patients who received TAU+ILF+CP demonstrated significantly greater improvement as a group when compared to TAU. When used as an integrative modality to treatment as usual in managing patients with PPCS, ILF neuromodulation with use of concussion protocol provided significant symptom improvements. (shrink)

Prior research has investigated the recruitment of inhibition in the use of science/mathematics concepts in tasks that require the rejection of a conflicting, nonscientific initial concept. The present research examines if inhibition is the only EF skill recruited in such tasks and investigates whether shifting is also involved. It also investigates whether inhibition and/or shifting are recruited in tasks in which the use of science/mathematics concepts does not require the rejection of an initial concept, or which require only the use (...) of initial concepts. One hundred and thirty‐three third‐ and fifth‐grade children participated in two inhibition and shifting tasks and two science and mathematics conceptual understanding and conceptual change (CU&C) tasks. All the tasks were on‐line, and performance was measured in accuracy and RTs. The CU&C tasks involved the use of initial concepts and of science/mathematics concepts which required conceptual changes for their initial formation. Only in one of the tasks the use of the science/mathematics concepts required the concurrent rejection of an initial concept. The results confirmed that in this task inhibition was recruited and also showed that the speed of shifting was a significant predictor of performance. Shifting was a significant predictor of performance in all the tasks, regardless of whether they involved science/mathematics or initial concepts. It is argued that shifting is likely to be recruited in complex tasks that require multiple comparisons of stimuli and the entertainment of different perspectives. Inhibition seems to be a more selective cognitive skill likely to be recruited when the use of science/mathematics concepts requires the rejection of a conflicting initial concept. (shrink)

This article presents the results of an experiment which investigated elementary school children's explanations of the day/night cycle. First, third, and fifth grade children were asked to explain certain phenomena, such as the disappearance of the sun during the night, the disappearance of stars during the day, the apparent movement of the moon, and the alteration of day and night. The results showed that the majority of the children in our sample used in a consistent fashion a small number of (...) relatively well‐defined mental models of the earth, the sun, and the moon to explain the day/night cycle. These mental models of the day/night cycle were empirically accurate, logically consistent and revealed some sensitivity on the part of the children to issues of simplicity of explanation. The younger children formed Initial mental models which provided explanations of the day/night cycle based on everyday experience (e.g., the sun goes down behind mountains, clouds cover up the sun). The older children constructed synthetic mental models (e.g., the sun and the moon revolve around the stationary earth every 24 hours; the earth rotates in an up/down direction and the sun and moon are fixed on opposite sides) which represented attempts to synthesize the culturally accepted view with aspects of their Initial models. A few of the older children appeared to have constructed a mental model of the day/night cycle similar to the scientific one. A theoretical framework is outlined which explains the formation of initial, synthetic, and scientific models of the day/night cycle in terms of the reinterpretation of a hierarchy of constraints, some of which are present early in the child's life, and others which emerge later out of the structure of the acquired knowledge.

The emerging area of philosophy of birth is invaluable, first, to diagnose fallacious assumptions about the relation between the womb and reason, and, ultimately, to challenge potentially damaging narratives with major impact on birth care. With its analysis of eighteenth-century epistemic and medical discussions about the role of the uterus in women's reasoning, this article supports two arguments: first, that women's “flawed thinking” was a premise drawn by many modern intellectual men, one that was presented as based upon empirical evidence; (...) and second, that the pervasive construction of the uterus as an element that renders women wild, uncontrollable, and irrational continues to influence contemporary obstetrics, even as today's medicine and science consider themselves to be free of any such prejudices.This article shows the role that Giacomo Casanova played in debunking these prejudices and presents his short manuscript on the issue as an important contribution to the literature of the Enlightenment, with its argument against women's supposed “natural” inferiority and for the idea that differences in education were to blame for women's subordinate position in society.Detailed analysis of the “thinking uterus” debate illuminates the different ways in which various arguments from/by the “anti-uterine” lobby were used to justify the subordination of women: sometimes emphasizing the connection between the uterus and thought and sometimes negating it, but always concluding that women's inferiority is to be found in some known or yet-to-be-discovered anatomical, and mainly sexual, deficiency or problem.

The current quality assurance culture demands the explicit articulation, by means of publication, of what have been hitherto tacit norms and conventions underlying disciplinary genres. The justification is that publication aids student performance and guarantees transparency and accountability. This requirement makes a number of questionable assumptions predicated upon what we will argue is an erroneous epistemology. It is not always possible to articulate in a publishable form a detailed description of disciplinary practices such as assessment. As a result publication cannot (...) achieve its stated goals. There are always elements of our knowledge that cannot be linguistically articulated. (shrink)

This article presents a new argument concerning the relation between Kant’s theory of race and aspects of the critical philosophy. It argues that Kant’s treatment of the problem of the systematic unity of nature and knowledge in the Critique of Pure Reason and the Critique of the Power of Judgment can be traced back a methodological problem in the natural history of the period – that of the possibility of a natural system of nature. Kant’s transformation of the methodological problem (...) from natural history into a set of philosophical problems proceeds by way of the working out of his own problem in natural history – the problem of the natural history of the human races – and specifically the problem of the unity in diversity of the human species, in response to which he develops a theory of race. This theory of race is, further, the first developed model of the use of teleological judgment in Kant’s work. The article thus argues that Kant’s philosophical position on the sy... (shrink)

Adult humans show exceptional relational ability relative to other species. In this research, we trace the development of this ability in young children. We used a task widely used in comparative research—the relational match-to-sample task, which requires participants to notice and match the identity relation: for example, AA should match BB instead of CD. Despite the simplicity of this relation, children under 4 years of age failed to pass this test (Experiment 1), and their performance did not improve even with (...) initial feedback (Experiment 2). In Experiments 3 and 4, we found that two kinds of symbolic-linguistic experience can facilitate relational reasoning in young children. Our findings suggest that children learn to become adept analogical thinkers, and that language fosters this learning in at least two distinct ways. (shrink)

Merleau-Ponty, Varela, Nagarjuna. Une triangulation possibleDans cet article, on voudrait mettre en évidence une triangulation possible entre Maurice Merleau-Ponty, le biologiste chilien Francisco Varela et le philosophebouddhiste de l’Antiquité Nagarjuna. L’objectif de cette perspective réside dans l’urgence d’une étude de la dynamique du réel, et même de la sensibilité en général.Dans The Embodied Mind, le « projet neuro-phénoménologique » et « l’urgence énactive » de Varela se joignent à la pratique bouddhiste Mahayana de Nagarjuna, à laquelle le biologiste consacre une (...) grande partie de son oeuvre. Ce rapprochement révèle l’intérêt de Varela pour l’ontologie bouddhiste, non substantielle et permanente, ce qui, non seulement le conduit jusqu’aux ultimes conséquences de la chair merleaupontienne, mais accroît aussi sa compréhension de la signification de cette chair.Dans les années précédant le développement de son ontologie, Merleau-Ponty se consacre à l’anthologie intitulée Les philosophes célèbres et décide d’y inclure un chapitre sur la philosophie orientale. Il y montre la nécessité d’un retour à l’Orient en tant qu’il a souvent été le précurseur et le « résonateur de notre rapport avec l’être ». Le présent travail se demande à quoi Merleau-Ponty fait allusion quand il nous invite « à mesurer les possibilités que nous nous sommes fermés en devenant ‘‘occidentaux’’ et, peut-être, à les rouvrir », afin d’établir la possibilité d’une convergence entre la chair, la constitution bouddhiste de la réalité et le projet énactif varélien.Merleau-Ponty, Varela, Nagarjuna. A Possible TriangulationIn this article, we would like to bring to light a possible triangulation between Maurice Merleau-Ponty, the Chilean biologist, Francisco Varela, and the ancientBuddhist philosopher, Nagarjuna. The purpose of doing this lies in the urgency of a study of the dynamic of the real and even of the sensible in general.In The Embodied Mind, Varela’s “neuro-phenomenological project” and the “enactive urgency” are joined to the Nagarjuna’s Mahayana Buddhist practice, to which the biologist devotes a large part of this work. This intersection reveals Varela’s interest in Buddhist ontology, an ontology that is non-substantialist and permanent. It leads not only to the ultimate consequences of Merleau-Ponty’s idea of the flesh, but also it adds its way of understanding to the significance of this flesh.In the years preceding the development of his ontology, Merleau-Ponty devoted himself to the anthology called Les philosophes célèbres. He decides to include in it a chapter on oriental philosophy. He shows there the necessity of a return to the Orient insofar as the East has often been the precursor and the “resonator of our relation to being.” The present work asks to what is Merleau-Ponty alluding when he invites us “to take stock of the possibilities in which we are enclosed by becoming ‘Western’ and perhaps we should reopen these possibilities” in order to establish the possibility of a convergence between the flesh, the Buddhist constitution of reality, and Varela’s enactive project.

Um das Ansehen von medizinischen Forschern ist es in der westlichen Welt nicht überall gut bestellt. In den 1990er-Jahren gelangte das Thema »Medizinischer Forschungsbetrug« erstmals in den USA in das öffentliche Bewusstsein. Eine Debatte um begünstigende Strukturen und denkbare Kontrollinstrumente zur Eindämmung von Missbrauch entbrannte – in Deutschland blieb ein solcher Diskurs bis zur Jahrhundertwende zunächst aus. Der Band nimmt wissenschaftlich arbeitende Ärzte, die ethischen Anforderungen, denen sie sich ausgesetzt sehen, und das System, in dem sie arbeiten, in den Fokus. (...)

Motivated by the work of Hardwig (1985, 1991) on epistemic dependence and trust in expertise, we enquire into the nature and extent of the critical assessment that non-scientists can make—and that they should be taught to make—with regard to science. Our thesis is that critical assessment of science is possible for non-experts because at the basis of science is a set of norms, beliefs and values that are contestable by non-scientists. These norms, beliefs and values are of critical importance to (...) science education and valuable to explore from a pedagogical perspective. (shrink)

Descartes’s doctrine of clarity and distinctness states that whatever is clearly and distinctly perceived is true. This paper looks at his early doctrine from Rules for the Direction of the Mind, and its application to the demarcation problem of curves in Descartes’s Geometry. This paper offers and defends a novel account of the demarcation criterion of curves: a curve is geometrical just in case it is clearly and distinctly perceivable. This account connects Descartes’s rationalist epistemological programme with his ontological views (...) about mathematics. (shrink)

In this article, I argue that Habermas’s genealogical approach to modern reason and methodological agnosticism can lead us to a better understanding of the role of religion in our societies. I underline the relevance of Habermas’s awareness that ‘something is missing’ when we take faith out of modernity and consider the truths of philosophical reason to be infallible. Habermas succeeds in highlighting the complexity of the modern relationship between the religious and the secular domains, a relationship that is not merely (...) epistemic, but also embodied in various practical relationships between religious and secular citizens. On this basis, and in the light of Habermas’s idea of modernity as an unfinished project, I argue that religion can be interpreted as a dimension allied to political modernity and democracy as well.

Festival is a performative dimension of cultural praxis that strengthens bonds of cohesion in society. Festivals are also an integral part of religious praxis. They have the potentiality of bringing its adherents and non-adherents together thus creating and sustaining social communion among them. This reality of sustaining social communion confirms an important function of religion in society with particular reference to its social integrative effects. Therefore, this article assesses how religious festival, Christmas, fosters social integration among Igbos in Nigeria. On (...) a related note, many Igbos, see Christmas festival as unique occasion for them to visit their communities; attend meetings of their associations and/or town unions and consolidate family ties. These are opportunities for building social integrations, otherwise denoted as social communion in this research. This work makes use of critical analysis of relevant texts and questionnaire survey methods as means of gathering materials and data for this research. In view of understanding how Christmas festival aids social communion among the Igbo ethnic group, the theories of structural functionalism, social capital and social integration are being utilised as theoretical frameworks for this study. Finally, this study avers that religious festival cements social communion between the Igbos in Calabar Metropolis and their ancestral communities. (shrink)

The argument of this paper hinges on Derrida's relation to Judaism as a religious heritage and/or as an essential experience. If he can be said to ‘appropriate his Jewish roots’ at all, as Colby Dickinson (2011) has recently proposed, this is not because Derrida concurs that all belief in an ultimate reality (‘as such’) must now be understood in merely conditional terms (‘as if’). Rather, it is because Derrida deconstructs the difference between the Jew and the non-Jew, along with the (...) differences between the ‘as if’ and the ‘as such’ and the performative and the constative, in his very demonstration of the impossibility of ‘being-jewish’. Dickinson thus misunderstands the way in which Derrida appropriates Kant's regulative ‘as if’, and thus misrepresents what is at stake in Derrida's ‘faith’ in ‘Jewishness’. What is at stake is what Derrida calls deconstructive responsibility, and it takes the form of a radical fidelity to the principle of reason (to an ‘unconditional theoreticism’). This responsibility, paradoxically, demands and impels the interrogation of critical thinking itself, with its principles, its essences and its identities. Accordingly, Derrida interrupts both the ‘as such’ and the ‘as if’ with the ‘if’ of a dangerous ‘perhaps’. (shrink)

The excavation of a ceramic workshop in the region of the ancient town of Corfu brought to light many elements connected with ceramic production. The workshop was in operation from the 5th to the 3rd c. BC. Among the remains of vases and other objects was a large number of small objects, chiefly of bronze and bone. A group of thirty-seven objects was identified, which could hâve been used by the potters and painters of the workshop as tools. A comparison (...) of these tools with those employed by contemporary potters produced interesting facts about their utilisation. Lastly, the places where the tools were found made it possible to clarify precisely the way in which the ancient workshop operated. (shrink)

Part way through Stephen Frears’s film, The Queen , the monarch undergoes an extraordinary, magical experience whilstjourneying into the Scottish landscape that surrounds Balmoral, her grandancestral holiday home.

While awaiting help a strangeevent occurs: a stag appears magically as if from nowhere and, unable tohide her admiration for the beast, the Queen gently (...) utters the words, ‘Oh!You beauty’ before the animal disappears as mysteriously as it arrived.Framed in a painterly way, and providing a marked punctuation to the urbansettings that have dominated the film so far, this short sequence presents aseries of sumptuous landscape images that elicit a spectator response whichis instinctive and intuitive. When analysed using an aesthetic approach – amethodology one might use for the examination of a painting – anemotional relationship is mobilised between the spectator and the film: asentiment not necessarily available through a narrative reading.
