En esta investigación se demuestra que no existe oposición antagónica entre la filosofía andina prehispánica y el desarrollo de la filosofía en general, ni con la filosofía occidental griega en particular, salvo en las formas de su temática especial o la profundización del problema filosófico concreto, por cuanto en ningún caso es contraria a la ley del desarrollo filosófico en general, y de ella debemos entender que los nombres, los términos o los vocablos con que designan los conceptos siendo distintos (...) tienen el mismo contenido y sigue igual lógica de desarrollo. Por ejemplo, “Pacha” resulta una formulación más cercana al concepto científico de espacio/tiempo, por cuanto adelanta la imposibilidad de separar el espacio y el tiempo de los objetos o fenómenos de la realidad objetiva, logrado no como un descubrimiento científico sino como una necesidad de formular el pensamiento acerca de dicho fenómeno, tan semejante a la ciencia moderna. O Cay y Camac, los conceptos de “materia” y de “realidad ideal”, perdidos u ocultos en los textos prehispánicos, son categorías que resuelven los problemas fundamentales de la filosofía, como acerca de “¿Cuál es el “verdadero ser”?”, o acerca de la relación ser y pensar. De igual modo consideramos que el idealismo andino prehispánico no difiere antagónicamente del idealismo griego clásico, contrariamente es posible discutir en el mismo nivel con Platón o con cualquier idealista de la filosofía clásica griega.

La investigación de la filosofía andina prehispánica, como historia de la filosofía, tiene el propósito descubrir los conceptos de la filosofía en un proceso histórico semejante al de la ciencia presocrática y el idealismo clásico griego, nada distinto de ellas. Esta describe la evolución de las ideas del hombre andino prehispánico, los conceptos que elaboró, manejo y uso en su pensamiento. El concepto de filosofía que asume deviene de Nietzsche, en cuanto pensamiento que se desarrolla con conceptos; la filosofía como (...) el juego de los conceptos, contestando a la pregunta que Engels, planteaba acerca de la relación entre el pensar y el ser, donde nacen los conceptos elementales de la filosofía; ella también sirve para explicar la relación de nuestros pensamientos con el mundo q.ue nos rodea, de si nuestro pensamiento es capaz de conocer el mundo real, de si con nuestras ideas podemos formarnos una imagen refleja exacta del mundo. Es decir, nuestra investigación responde en qué medida el pensamiento andino prehispánico, como indica Hegel, es la teoría del conocimiento de su tiempo, como un pensamiento que se ocupa de sí mismo porque es el objeto de estudio, como pensamiento que “se piensa a sí mismo” respecto sus diferentes determinaciones.

Sensory processing dysfunction is characterized by a behaviorally observed difference in the response to sensory information from the environment. While the cerebellum is involved in normal sensory processing, it has not yet been examined in SPD. Diffusion tensor imaging scans of children with SPD and typically developing controls were compared for fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity across the following cerebellar tracts: the middle cerebellar peduncles, superior cerebellar peduncles, and cerebral peduncles. Compared to TDC, children with SPD (...) show reduced microstructural integrity of the SCP and MCP, characterized by reduced FA and increased MD and RD, which correlates with abnormal auditory behavior, multisensory integration, and attention, but not tactile behavior or direct measures of auditory discrimination. In contradistinction, decreased CP microstructural integrity in SPD correlates with abnormal tactile and auditory behavior and direct measures of auditory discrimination, but not multisensory integration or attention. Hence, altered cerebellar white matter organization is associated with complex sensory behavior and attention in SPD, which prompts further consideration of diagnostic measures and treatments to better serve affected individuals.

The idea that democracy is under threat, after being largely dormant for at least 40 years, is looming increasingly large in public discourse. Complex systems theory offers a range of powerful new tools to analyse the stability of social institutions in general, and democracy in particular. What makes a democracy stable? And which processes potentially lead to instability of a democratic system? This paper offers a complex systems perspective on this question, informed by areas of the mathematical, natural, and social (...) sciences. We explain the meaning of the term 'stability' in different disciplines and discuss how laws, rules, and regulations, but also norms, conventions, and expectations are decisive for the stability of a social institution such as democracy.

What is the future of Philosophy of education? Or as many of scholars and thinkers in this final ‘future-focused’ collective piece from the philosophy of education in a new key Series put it, what are the futures—plural and multiple—of the intersections of ‘philosophy’ and ‘education?’ What is ‘Philosophy’; and what is ‘Education’, and what role may ‘enquiry’ play? Is the future of education and philosophy embracing—or at least taking seriously—and thinking with Indigenous ethicoontoepistemologies? And, perhaps most importantly, what is that (...) ‘Future’? These debates have been located in the work of diverse scholars: from the West, from Global South, from indigenous thinkers. In this collective piece, we purposefully juxtapose diverse takes on the future of these intersections. We have given up the urge to organise, place together, separate with subheadings or connect the paragraphs that follow. Instead, we let these philosophers of education and thinkers who use philosophical texts and ideas to sit together in one long read as potentially ‘strange and unusual bedfellows’. This text urges us to understand how these scholars and thinkers perceive our educational philosophical futures, and how the work and thinking they have done on thinking about what the future of that new key in philosophy of education may look like is embedded in a much deeper and richer literature, and personal experience.

The aim of this study was to explore the note-taking experiences of university students using paper-based and paperless resources. By means of a hermeneutic phenomenological approach, the note-taking experiences of 18 students from an international program at a university in Belgium were examined throughout a semester. In order to document these students’ practices with paper-based and paperless resources, four data collection methods were used: in-depth interviews observations focus group discussions and document analysis of students’ lecture notes. The results showed that (...) students experience note-taking as a complex phenomenon in which lived body, lived human relations, lived space and lived time come into play, and in which they try to find a balance between multiple engagements, between autonomy and authority, between attention and distraction, and between being original and mirroring others. This struggle for balance occurs irrespective of which medium they choose to use. These results provide an in-depth view of the phenomenon, and also highlight the complexity of the note-taking experience. (shrink)
Different explanations of color vision favor different philosophical positions: Computational vision is more compatible with objectivism (the color is in the object), psychophysics and neurophysiology with subjectivism (the color is in the head). Comparative research suggests that an explanation of color must be both experientialist (unlike objectivism) and ecological (unlike subjectivism). Computational vision's emphasis on optimally prespecified features of the environment (i.e., distal properties, independent of the sensory-motor capacities of the animal) is unsatisfactory. Conceiving of visual perception instead as the (...) visual guidance of activity in an environment that is determined largely by that very activity suggests new directions for research. (shrink)
I analyze the extent to which classical phase transitions, both first order and continuous, pose a challenge for intertheoretic reduction. My contention is that phase transitions are compatible with a notion of reduction that combines Nagelian reduction and what Thomas Nickles called Reduction2. I also argue that, even if the same approach to reduction applies to both types of phase transitions, there is a crucial difference in their physical treatment: in addition to the thermodynamic limit, in continuous phase transitions there (...) is a second infinite limit involved, which marks an important difference in the reduction of first-order and continuous phase transitions.

This paper examines whether there are moral differences between the mitochondrial replacement techniques that have been recently developed in order to help women afflicted by mitochondrial DNA diseases to have genetically related children absent such conditions: maternal spindle transfer and pronuclear transfer. Firstly, it examines whether there is a moral difference between MST and PNT in terms of the divide between somatic interventions and germline interventions. Secondly, it considers whether PNT and MST are morally distinct under a therapy/creation optic. Finally, (...) it investigates whether there is a moral difference between MST and PNT from a human embryo destruction point of view. I conclude, contra recent arguments, that regarding the first two points there is no moral differences between PNT and MST; and that regarding the third one MST is morally preferable to PNT, but only if we hold a gradualist account of the moral value of human embryos where zygotes have slight moral value.

The recent resurgence of extreme-right movements and the nationalist turn of many governments across the world have reignited the relevance of discussions within educational philosophy about the teaching of national identity in schools. However, the conceptualisation of national identity in previous iterations of these debates have been largely Western and Eurocentric, making the past theoretical literature about these questions less relevant for post-colonial settings. In this paper, I imagine a new approach for teaching national identity in post- colonial contexts, founded (...) on postcolonial conceptions of identity and in particular, the concept of hybridity. I first develop a postcolonial account of national identity by drawing on Homi Bhabha’s thinking about cultural identity, drawing on his concepts of liminality, splitting, and ambivalence. Then, building on Bhabha’s notion of hybridity, I propose a distinction between national identity portrayals as either fixed or malleable. Finally, I demonstrate the implications of such a conceptual distinction on the way that national identity is taught in post-colonial schools; by way of an example, I envision a concrete approach to teaching national identity that views national identity as malleable rather than fixed, set in a hypothetical postcolonial school in the Philippines. By beginning from postcolonial assumptions about national identity, I hope to indicate new directions that the debates about the teaching of national identity in schools might proceed. (shrink)
In this work I present a detailed critique of the dignity-related arguments that have been advanced against the creation of human–nonhuman chimeras that could possess human-like mental capacities. My main claim is that the arguments so far advanced are incapable of grounding a principled objection against the creation of such creatures. I conclude that these arguments have one, or more, of the following problems: they confuse the ethical assessment of the creation of chimeras with the ethical assessment of how such (...) creatures would be treated in specific contexts, they misrepresent how a being could be treated solely as means towards others’ ends, they fall short of demonstrating how humanity’s dignity would be violated by the creation of such entities, and they fail to properly characterise the moral responsibilities that moral agents have towards other moral agents and sentient beings.

In this paper, I analyze the extent to which classical phase transitions, especially continuous phase transitions, impose a challenge for reduction- ism. My main contention is that classical phase transitions are compatible with reduction, at least with the notion of limiting reduction, which re- lates the behavior of physical quantities in different theories under certain limiting conditions. I argue that this conclusion follows even after rec- ognizing the existence of two infinite limits involved in the treatment of continuous phase transitions.
Jürgen Habermas is regarded as a central bioconservative commentator in the debate on the ethics of human prenatal genetic manipulations. While his main work on this topic, The Future of Human Nature, has been widely examined in regard to his position on prenatal genetic enhancement, his arguments regarding prenatal genetic therapeutic interventions have for the most part been overlooked. In this work I do two things. First, I present the three necessary conditions that Habermas establishes for a prenatal genetic manipulation (...) to be regarded as morally permissible. Second, I examine if mitochondrial replacement techniques meet these necessary conditions. I investigate, specifically, the moral permissibility of employing pronuclear transfer and maternal spindle transfer. I conclude that, according to a Habermasian perspective on prenatal genetic manipulation, maternal spindle transfer and pronuclear transfer are morally impermissible. Maternal spindle transfer is, in principle, morally permissible, but only when we have beforehand preselected a sperm and an egg for our reproductive purpose. These findings are relevant for bioconservatives, both for those who hold a Habermasian stance and for those who hold something akin to a Habermasian stance, because they answer the question: what should bioconservatives do regarding mitochondrial replacement techniques? In fact, the answer to this question does not only normatively prescribe what bioconservatives should do in terms of their personal morality, but it also points towards what kind of legislation regulating mitochondrial replacement techniques they should aim at.

This article develops a diagnostic lens to make sense of the still baffling development of a ‘humanitarian marketplace’. Ambivalently hybrid initiatives such as volunteer tourism, corporate social responsibility or even fair trade do not strictly obey a distributive logic of market exchange, social reciprocity or philanthropic giving. They engender a type of ‘economy’ that must be apprehended in its own terms. The article argues that the large-scale collaborative effects of such a dispersed market can be theorized without resorting to the (...) classical biopolitical move of simplified agency/holistic reification. The argument proceeds counterintuitively, by appropriating the notion of symbiosis as redefined by contemporary biology, contending through historical contextualization and conceptual work that nature itself offers the best example to grasp spontaneous collaboration among unrelated human beings as a non-automatically balanced and intrinsically political affair that calls for critical management through an ex post facto interventionist policy of selective cultivation.

The aim of this paper is to critically examine David Shaw, Wybo Dondorp, and Guido de Wert’s arguments in favour of the procurement of human organs from human/nonhuman-primate chimeras, specifically from great-ape/human chimeras. My main claim is that their arguments fail and are in need of substantial revision. To prove this I first introduce the topic, and then reconstruct Shaw et al.’s position and arguments. Next, I show that Shaw et al.: failed to properly apply the subsidiarity and proportionality principles; (...) neglected species overlapping cases in their ethical assessment; ignored the ethics literature on borderline persons; and misunderstood McMahan’s two-tiered moral theory. These mistakes render an important part of their conclusions either false or problematic to the point that they would no longer endorse them. Finally I will briefly mention a possible multipolar solution to the human organ shortage problem that would reduce the need for chimeras’ organs. (shrink)
Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between goal-directed and stimulus-driven factors. However, the neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress can modulate brain rhythms during an attentional task and a task-free period. We recorded the EEG and ECG activity of 42 healthy participants subjected to either the Trier Social Stress Test, a controlled procedure to (...) induce stress, or a comparable control protocol, flanked by an attentional task, a 90 s of task-free period and a state of anxiety questionnaire. We observed that psychosocial stress induced an increase in heart rate, self-reported anxiety, and alpha power synchronization. Also, psychosocial stress evoked a relative beta power increase during correct trials of the attentional task, which correlates positively with anxiety and heart rate increase, and inversely with attentional accuracy. These results suggest that psychosocial stress affects performance by redirecting attentional resources toward internal threat-related thoughts. An increment of endogenous top-down modulation reflected an increased beta-band activity that may serve as a compensatory mechanism to redirect attentional resources toward the ongoing task. The data obtained here may contribute to designing new ways of clinical management of the human stress response in the future and could help to minimize the damaging effects of persistent stressful experiences.

Clinical photography is an important tool for medical practice, training and research. While in the past clinical pictures were confined to the stringent controls of surgeries and hospitals technological advances have made possible to take pictures and share them through the internet with only a few clicks. Confronted with this possibility I explore if a case could be made for using clinical photography in tandem with social media. In order to do this I explore: if patient’s informed consent is required (...) for the publication of any clinical images that depicts her, irrespective of whether the patient can be identified from the image or not, if social media is an adequate place for clinical images to be displayed, and finally if there are special considerations that should be taken into account when publishing clinical images on social media.

Aim: The present work proposes the study of the neuromotor activity of the masseter-jaw-tongue articulation during diadochokinetic exercising to establish functional statistical relationships between surface Electromyography, 3D Accelerometry, and acoustic features extracted from the speech signal, with the aim of characterizing Hypokinetic Dysarthria. A database of multi-trait signals of recordings from an age-matched control and PD participants are used in the experimental study. Hypothesis: The main assumption is that information between sEMG and 3D acceleration, and acoustic features may be quantified (...) using linear regression methods. Methods: Recordings from a cohort of eight age-matched control participants and eight PD participants were collected during the utterance of a diadochokinetic exercise. The dynamic and acoustic absolute kinematic velocities produced during the exercises were estimated by acoustic filter inversion and numerical integration and differentiation of the speech signal. The amplitude distributions of the absolute kinematic and acoustic velocities are estimated to allow comparisons in terms of Mutual Information. Results: The regression results show the relationships between sEMG and dynamic and acoustic estimates. The projection methodology may help in understanding the basic neuromotor muscle activity regarding neurodegenerative speech in remote monitoring neuromotor and neurocognitive diseases using speech as the vehicular tool, and in the study of other speech-related disorders. The study also showed strong and significant cross-correlations between articulation kinematics, both for the control and the PD cohorts. The absolute kinematic variables presents an observable difference for the PD participants compared to the control group. Conclusion: Kinematic distributions derived from acoustic analysis may be useful biomarkers toward characterizing HD in neuromotor disorders providing new insights into PD. (shrink)
Se não se ensina filosofia, mas a filosofar (Kant), como se ensina a filosofar? Obviamente, filosofando. Por outro lado, se a filosofia não se define por um objeto próprio nem a distingue um só método privilegiado, em que consiste, então, essa ação que o filosofar aponta? Que a filosofia não se define por um objeto nem por um método parece claro. No entanto, algo, em geral, deve caracterizar o filosofar. O que parece caracterizá-lo, mesmo que negativamente, é a tentativa de (...) resolução de problemas que com o resultado de outras ciências ou do conhecimento obtido em outras áreas da atividade humana é impossível resolver.

Neste caso, pelo exemplo de um agir filosofante, ou seja, discutindo, avaliando e procurando respostas aos problemas que a cada um de nós, filosoficamente, nos preocupam. (shrink)
In the first wave of the COVID-19 pandemic, healthcare workers in some countries were forced to make distressing triaging decisions about which individual patients should receive potentially life-saving treatment. Much of the ethical discussion prompted by the pandemic has concerned which moral principles should ground our response to these individual triage questions. In this paper we aim to broaden the scope of this discussion by considering the ethics of broader structural allocation decisions raised by the COVID-19 pandemic. More specifically, we (...) consider how nations ought to distribute a scarce life-saving resource across healthcare regions in a public health emergency, particularly in view of regional differences in projected need and existing capacity. We call this the regional triage question. Using the case study of ventilators in the COVID-19 pandemic, we show how the moral frameworks that we might adopt in response to individual triage decisions do not translate straightforwardly to this regional-level triage question. Having outlined what we take to be a plausible egalitarian approach to the regional triage question, we go on to propose a novel way of operationalising the ‘save the most lives’ principle in this context. We claim that the latter principle ought to take some precedence in the regional triage question, but also note important limitations to the extent of the influence that it should have in regional allocation decisions.

We study the Johansen–Ledoit–Sornette model of financial market crashes :219–255, 2000). On our view, the JLS model is a curious case from the perspective of the recent philosophy of science literature, as it is naturally construed as a “minimal model” in the sense of Batterman and Rice :349–376, 2014) that nonetheless provides a causal explanation of market crashes, in the sense of Woodward’s interventionist account of causation.
According to the free energy principle, life is an “inevitable and emergent property of any random dynamical system at non-equilibrium steady state that possesses a Markov blanket” :20130475, 2013). Formulating a principle for the life sciences in terms of concepts from statistical physics, such as random dynamical system, non-equilibrium steady state and ergodicity, places substantial constraints on the theoretical and empirical study of biological systems. Thus far, however, the physics foundations of the free energy principle have received hardly any attention. (...) Here, we start to fill this gap and analyse some of the challenges raised by applications of statistical physics for modelling biological targets. Based on our analysis, we conclude that model-building grounded in the free energy principle exacerbates a trade-off between generality and realism, because of a fundamental mismatch between its physics assumptions and the properties of actual biological targets.

Political scientists have conventionally assumed that achieving democracy is a one-way ratchet. Only very recently has the question of ‘democratic backsliding’ attracted any research attention. We argue that democratic instability is best understood with tools from complexity science. The explanatory power of complexity science arises from several features of complex systems. Their relevance in the context of democracy is discussed. Several policy recommen- dations are offered to help stabilize current systems of representative democracy.
Labor, work, and action are the three activities which form vita activa for Hannah Arendt. Action is the activity on which she built her political thought, so literature has focused on it. Thus, labor and work have been relegated to the background, ignoring what both retain and illuminate. The article shows the difficulties of the slippery distinction between labor and work, especially when labor and work are understood as concepts, crystallizations of the phenomena Arendt intended to capture. Instead, it proposes (...) that labor and work acquire their deepest meaning when understood as experiences, that is, the mentalities and ways of life of animal laborans and homo faber, always within Arendt’s effort to understand Modernity and totalitarianism.

Abstract Background The first live birth following the use of a new reproductive technique, maternal spindle transfer (MST), which is a mitochondrial replacement technique (MRT), was accomplished by dividing the execution of the MST procedure between two countries, the USA and Mexico. This was done in order to avoid US legal restrictions on this technique. -/- Sources of data Academic articles, news articles, documents obtained through freedom of information requests, laws, regulations and national reports. -/- Areas of agreement MRTs are (...) new reproductive techniques that present novel ethical and legal challenges, since genetic material from three people is employed to create a child. -/- Areas of controversy Could the first MST procedure that culminated in a live birth negatively impact reproductive medicine in Mexico? -/- Growing points The USA and Mexico need specific and clear legislation on MRTs, in order for such techniques not to be governed by prior existing legislation on assisted reproduction that is inadequate for dealing with the new challenges that these techniques present. -/- Areas timely for developing research There is a pressing need for work to be done on the international governance of new reproductive techniques.

In this paper, we argue that lesbian couples who wish to have children who are genetically related to both of them should be allowed access to mitochondrial replacement techniques. First, we provide a brief explanation of mitochondrial diseases and MRTs. We then present the reasons why MRTs are not, by nature, therapeutic. The upshot of the view that MRTs are non-therapeutic techniques is that their therapeutic potential cannot be invoked for restricting their use only to those cases where a mitochondrial (...) DNA disease could be ‘cured’. We then argue that a positive case for MRTs is justified by an appeal to reproductive freedom, and that the criteria to access these techniques should hence be extended to include lesbian couples who wish to share genetic parenthood. Finally, we consider a potential objection to our argument: that the desire to have genetically related kin is not a morally sufficient reason to allow lesbian couples to access MRTs. (shrink)

A physically consistent semi-classical treatment of black holes requires universality arguments to deal with the `trans-Planckian' problem where quantum spacetime effects appear to be amplified such that they undermine the entire semi-classical modelling framework. We evaluate three families of such arguments in comparison with Wilsonian renormalization group universality arguments found in the context of condensed matter physics. Our analysis is framed by the crucial distinction between robustness and universality. Particular emphasis is placed on the quality whereby the various arguments are (...) underpinned by `integrated' notions of robustness and universality. Whereas the principal strength of Wilsonian universality arguments can be understood in terms of the presence of such integration, the principal weakness of all three universality arguments for Hawking radiation is its absence.
