Ontologies formally represent reality in a way that limits ambiguity and facilitates automated reasoning and data fusion, but is often daunting to the non-technical user. Thus, many researchers have endeavored to hide the formal syntax and semantics of ontologies behind the constructs of Controlled Natural Languages (CNLs), which retain the formal properties of ontologies while simultaneously presenting that information in a comprehensible natural language format. In this paper, we build upon previous work in this field by evaluating prospects of implementing (...) International Technology Alliance Controlled English (ITACE) as a middleware for ontology editing. We also discuss at length a prototype of a natural language conversational interface application designed to facilitate ontology editing via the formulation of CNL constructs. (shrink)

Developmental coordination is vital in the temporally coordinated appearance of cell types within the precise spatial architecture of the vertebrate brain and this, combined with the rich interplay between the developing brain and its target organs, is a biological problem of monumental complexity. An example is the genesis and subsequent integration of the neuroendocrine hypothalamus and the pituitary. Two recent papers(1,2) use the developing hypothalamo‐pituitary axis in order to gather a deeper understanding of these integrative mechanisms. In addition, they show (...) that a sub‐family of homeodomain factors, the POU‐domain proteins, play a critical role in coordinating the respective ontogenies of the hypothalamus and the pituitary.

Neurotheology is a fast-growing field of research. Combining philosophy of mind, neuroscience, and religious studies, it takes a new approach to old questions on religion. What is religion and why do we have it? Neurotheologists focus on the search for the neural correlate of religious experiences. If we can trace religious experiences to specific parts of the brain, chances are we can reduce religion as such to that grey soggy matter as well. This article predicts neurotheology will not be able (...) to locate the neural correlate of religious experiences. As we cannot decide phenomenally what makes an experience religious, neurologically we cannot find its correlate either. That is, if there are fixed neural correlates to begin with, because their existence is still a matter of debate. In addition, religious experiences seem to be a kind of experience, like emotional or relational experiences, making them indistinguishable from similar nonreligious experiences. Even if one manages to trace the neural correlate of religious experiences, neurotheology will still not be able to account for the rise of religion without resorting to theories from other disciplines. In the end, we do not know enough about consciousness and the way it relates to the brain to make conclusive claims about the search for religious states of consciousness. It seems, however, that even though neurotheology could provide fascinating insights in the workings of the religious brain, on its own, it will prove unable to explain religion fully. (shrink)

This commentary reviews recent evidence that some hippo- campal functions do not depend on perirhinal inputs and discusses how the multiple-process model of recognition may shed interpretive light on previous reports of DNMS reacquisition deficits in pretrained subjects with hippocampal damage. Suggestions are made for determining whether nonhuman subjects solve object-recognition tasks using recollective memory or familiarity judgments.

Eichenbaum et al. (1994a) hypothesized that perceptually distinct items and the relations among them are processed sequentially by the parahippocampal region and the hippocampal formation, respectively. Predictions based solely on their model's sequential-processing feature might prove easier to disconfirm than those based on its representational features. Two such predictions are discussed: (1) double dissociations should be impossible following hippocampal vs. parahippocampal lesions, and (2) hippocampal lesions should not exacerbate impairments that follow complete parahippocampal lesions.

This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

In this wide-ranging interview, Dave Elder-Vass discusses his main contributions to critical realist theory over two decades. In the first half, he explains his early work on emergence, agency, str...

Clinical research with adults who are unable to provide informed consent has the potential to improve understanding and care of a number of devastating conditions. This research also has the potential to exploit some of society's most vulnerable members. Recently, a number of task forces and individual writers have proposed guidelines to ensure that such research is both possible and ethical. Yet, there is widespread disagreement over which safeguards should be adopted. In the present paper, I consider to what extent (...) these disagreements can be resolved by appeal to a general account of the interests of subjects who are unable to consent and the conditions that must be satisfied for research enrollment to constitute exploitation of their inability to make their own decisions.

Mark Coeckelbergh argues that Romanticism and the Enlightenment philosophies are not that far apart when it comes to philosophy of technology.

Aspects of peroxisome evolution, uncoupling, carnitine shuttles, supercomplex formation, and missing neuronal fatty acid oxidation (FAO) are linked to reactive oxygen species (ROS) formation in respiratory chains. Oxidation of substrates with high FADH2/NADH (F/N) ratios (e.g., FAs) initiate ROS formation in Complex I due to insufficient availability of its electron acceptor (Q) and reverse electron transport from QH2, e.g., during FAO or glycerol‐3‐phosphate shuttle use. Here it is proposed that the Q‐cycle of Complex III contributes to enhanced ROS formation going (...) from low F/N ratio substrates (glucose) to high F/N substrates. This contribution is twofold: 1) Complex III uses Q as substrate, thus also competing with Complex I; 2) Complex III itself will produce more ROS under these conditions. I link this scenario to the universally observed Complex III dimerization. The Q‐cycle of Complex III thus again illustrates the tension between efficient ATP generation and endogenous ROS formation. This model can explain recent findings concerning succinate and ROS‐induced uncoupling. (shrink)

How should accounts that stress the embodied, embedded and engaged character of human minds accommodate the role of rationality in human subjectivity? Drawing on Matthew Boyle’s contrast between ‘additive’ and ‘transformative’ conceptions of rationality, I argue that contemporary work on embodied cognition tends towards a problematic ‘additivism’ about the relationship between mature human capacities to think and act for reasons, and sensorimotor capacities to skillfully engage with salient features of the environment. Additivists view rational capacities to reason and reflect as (...) a distinct ‘layer’ or ‘storey’ of human cognition, with a normative structure that differs from that of the sensorimotor coping skills which support it. I argue that emphasizing the embodied and engaged character of human minds is better combined with a ‘transformative’ conception of rationality – one which holds that acquiring abilities to give and ask for reasons transforms the normative structure of our unreflective embodied dealings with the environment. And I argue that a transformative embodied cognitive science of human rationality is not only possible, but underway. Integrating existing work on embodied cognition with work on the cultural and developmental contexts that shape human minds suggests how human immersion in culture transforms the structure of sensorimotor engagements by bringing about the communicability and negotiability of the meanings to which those engagements attune us.

Although inquiry-based instruction has been a centerpiece of progressive visions of social studies education almost since its inception as a school subject a century ago, teachers often struggle to conceptualize it in ways that make true inquiry possible for their students.

In the 1950s, Noam Chomsky offered a new vision for linguistic research and syntacticians. This chapter explores some ways in which Chomsky's linguistic work has influenced research on one domain of linguistic performance, sentence processing, over the last half century. It shows that Chomsky's claim in Aspects of the Theory of Syntax is largely borne out: "the study of performance will proceed only as far as the study of the underlying competence permits". The chapter briefly addresses a question about the (...) scope of modern sentence processing research and its relationship to specific grammatical formalisms. It reviews the literature on incremental ambiguity resolution, moves to the processing of long‐distance filler‐gap dependency processing, and provides information on the processing of anaphoric relations. In order to illustrate how the phenomenon has contributed to psycholinguistic theorizing, the chapter outlines a well‐known model and then considers how other models diverge. (shrink)

Of two contending models for eukaryotic evolution the “archezoan“ has an amitochondriate eukaryote take up an endosymbiont, while “symbiogenesis“ states that an Archaeon became a eukaryote as the result of this uptake. If so, organelle formation resulting from new engulfments is simplified by the primordial symbiogenesis, and less informative regarding the bacterium‐to‐mitochondrion conversion. Gradualist archezoan visions still permeate evolutionary thinking, but are much less likely than symbiogenesis. Genuine amitochondriate eukaryotes have never been found and rapid, explosive adaptive periods characteristic of (...) symbiogenetic models explain this. Mitochondrial proteomes, encoded by genes of “eukaryotic origin“ not easily linked to host or endosymbiont, can be understood in light of rapid adjustments to new evolutionary pressures. Symbiogenesis allows “expensive” eukaryotic inventions via efficient ATP generation by nascent mitochondria. However, efficient ATP production equals enhanced toxic internal ROS formation. The synergistic combination of these two driving forces gave rise to the rapid evolution of eukaryotes.Also watch the Video Abstract. (shrink)

An expanded edition of Hickey's controversial and exquisitely written apologia for beauty--championed by artists, reviled by art critics, and as powerful as ever 30 years on 1993: the AIDS pandemic rages through yet another decade, leaving society and the arts devastated and bereft. Dave Hickey sits down to produce a slim volume, The Invisible Dragon. The book ignites a firestorm, and from its ashes "beauty" again rises as a dominant force in artistic life. Academics argue about theoretical minutiae. Artists (...) pass the book around like a samizdat. This 30th-anniversary edition brings back into print Dragon's four essays on beauty and commingles them with five previously uncollected essays. Hickey's 1974 profile of Dolly Parton anticipates Dolly's longevity as a cultural and feminist icon; his appreciation of Richard Pryor weaves an elegiac tapestry; his review of John Rechy's seminal gay novel Numbers outs its literary innovation in the face of a homophobia that otherwise ghettoized it; and his singular essay on Ed Ruscha, a paragon of arts writing by an extraordinary prose stylist, enjoins us to listen to art, not just look at it. An afterword by Hickey's friend and Dragon's editor "queers" the brash, heterosexual gambler as it situates the creation of Dragon squarely within the AIDS pandemic. The book was in part an attempt to make beauty visible under the looming presence of death and bodily decay. Only now can we fully appreciate how artists continue to harness beauty as a source of meaning and joy. Dave Hickey (1938-2021) was one of the preeminent arts and cultural writers of the turn of the 21st century. A MacArthur "Genius" Fellow known as the "beauty guy" in the popular press, Hickey opened A Clean, Well-Lighted Place gallery in Austin, Texas, in the 1960s, before becoming executive editor at Art in America magazine. In the 1970s, he was a songwriter in Nashville, Tennessee, where he coined and helped create the "Outlaw country" music movement. By the 1990s, Hickey had made a home in Las Vegas, from where he regularly traveled to speak with audiences worldwide. (shrink)

Skepticism about the limits of online learning is as old as online learning itself. As with other technologically-driven innovations in pedagogy, there are deep-seated worries that important educational goods might be effaced or obscured by the ways of teaching and learning that online methods allow. One family of such worries is inspired by reflections on the bodily basis of an important kind of understanding, and skepticism over whether this bodily basis can be inculcated in the absence of actual, flesh-and-blood, classroom (...) interactions. This paper focuses on the ways in which such worries arise in the influential work of Hubert Dreyfus. The negative conclusion for which I argue is that endorsing Dreyfus's Merleau-Pontian picture of the relationship between bodily skill and understanding does not commit us to his general pessimism concerning online learning—bodily, emotional, and interactive dimensions might be essential to learning, but we lack reasons to think that online learning necessarily lacks these dimensions. The negative argument motivates a positive claim: rather than giving up on online learning we should focus on designing courses and pedagogies that scaffold the bodily, affective and interactive dynamics constitutive of understanding in a particular domain.

Group sex among men who have sex with men may be understood as a ‘radical’ practice insofar as it transgresses dominant social discourses around appropriate sexual relations—prioritizing heteronormative, monogamous and risk‐averse sex. These practices are generally defined as steeped in risk, most commonly due to the potential for transmitting human immunodeficiency virus and sexually transmitted infections and accompanied by the possibility of legal and social repercussions. Our ethnographic research study explored the desires, practices and contexts of group sex participants (n (...) = 10) within a popular group sex party destination located in the United States. We employ a poststructuralist perspective (utilizing the work of Deleuze and Guattari) to understand group sex events with the pretext that bodies have no inherent ethics, meaning or essence: they are ‘bodies without organs’. We identify group sex as a form of boundary play, in which participants pursue new limits to what their bodies can do but within a carefully constructed environment that establishes norms of interaction meant to secure trust and safety between participants. A variety of risk reduction practices are shown to be promoted and honoured within these eventful sexual(ized) spaces. The application of poststructuralist concepts of ‘boundary play’ and ‘bodies without organs’ helped to depict the construction and navigation of pleasure, safety and risk among group sex participants.

As free‐living organisms, alpha‐proteobacteria produce reactive oxygen species (ROS) that diffuse into the surroundings; once constrained inside the archaeal ancestor of eukaryotes, however, ROS production presented evolutionary pressures – especially because the alpha‐proteobacterial symbiont made more ROS, from a variety of substrates. I previously proposed that ratios of electrons coming from FADH2 and NADH (F/N ratios) correlate with ROS production levels during respiration, glucose breakdown having a much lower F/N ratio than longer fatty acid (FA) breakdown. Evidently, higher endogenous ROS (...) formation did not hinder eukaryotic evolution, so how were its disadvantages mitigated? I propose that the resulting selection pressures favoured the evolution of a variety of eukaryotic ‘innovations’: peroxisomes for FA breakdown, carnitine shuttles, the linkage of beta‐oxidation to antioxidant properties, uncoupling proteins (UCPs) and using mitochondrial uncoupling during beta‐oxidation to reduce ROS. Recently observed relationships between peroxisomes and mitochondria further support the model. (shrink)

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, that (...) the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

Recently, the group of McBride reported a stunning observation regarding peroxisome biogenesis: newly born peroxisomes are hybrids of mitochondrial and ER-derived pre-peroxisomes. What was stunning? Studies performed with the yeast Saccharomyces cerevisiae had convincingly shown that peroxisomes are ER-derived, without indications for mitochondrial involvement. However, the recent finding using fibroblasts dovetails nicely with a mechanism inferred to be driving the eukaryotic invention of peroxisomes: reduction of mitochondrial reactive oxygen species generation associated with fatty acid oxidation. This not only explains the (...) mitochondrial involvement, but also its apparent absence in yeast. The latest results allow a reconstruction of the evolution of the yeast's highly derived metabolism and its limitations as a model organism in this instance. As I review here, peroxisomes are eukaryotic inventions reflecting mutual host endosymbiont adaptations: this is predicted by symbiogenetic theory, which states that the defining eukaryotic characteristics evolved as a result of mutual adaptations of two merging prokaryotes. See also the video abstract here: https://youtu.be/HtyKhQ3DSxg Eukaryotic peroxisomes illustrate effects of symbiogenesis, following the non-phagocytotic merger of an archaeon and a bacterium. Internal ROS formation upon fatty acid oxidation was reduced by the invention of peroxisomes for extra-mitochondrial FA oxidation. Both peroxisomal membranes and their oldest enzymes seem ultimately derived from the pre-mitochondrion. (shrink)

Meyer and Brancazio make an important distinction between two enactivist projects: “utopian” and “scientific.” I agree that contemporary enactivists would benefit from more clearly distinguishing these projects and their success conditions. However, I wonder whether there are times when letting these projects merge with each other might be helpful, or even necessary.

The transparency of perceptual experience has been invoked in support of many views about perception. I argue that it supports a form of enactivism—the view that capacities for perceptual experience and for intentional agency are essentially interdependent. I clarify the perceptual phenomenon at issue, and argue that enactivists should expect to find a parallel instance of transparency in our agentive experience, and that the two forms of transparency are constitutively interdependent. I then argue that i) we do indeed find such (...) parallels: the way in which an action is directed towards its goal through our bodily movements parallels the way in which an experience is directed towards its object through our perceptual sensation, and ii) reflecting on sensorimotor skills shows why the two instances of transparency are constitutively interdependent. Section 4 gives reasons for generalizing beyond the cases considered so far by applying the enactive view to Kohler's landmark studies of perceptual adaptation. The final section clarifies the form of enactivism to which the previous sections point. The view that emerges is one whereby our perceptual and practical skills are interrelated aspects of a single capacity to have one's mind intentionally directed upon the world. The transparency of experience, on this view, is achieved in virtue of our capacities as agents as much as it is given in virtue of our capacities as perceivers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric and Power: An Inquiry into Foucault’s Critique of ConfessionDave TellOn October 10, 1979, Michel Foucault revised his thesis on confession. On that day, some three years after the publication of his magisterial treatment of confession in the first volume of The History of Sexuality, Foucault argued that the Pythagoreans, Stoics, and Epicureans had, before the advent of Christianity, their own practices of confession. Yet these practices, unlike their (...) Christian variants, were not complicit with practices of domination (OS 310, 312). In the context of Foucault’s thought theretofore, in which the confession consistently figured as an essential component in the exercise of modern power, this is a radical shift. In lectures given at both Berkeley and Dartmouth in the fall of 1980, Foucault made similar arguments. On these occasions he argued that Seneca’s De ira constituted a “stoic confession,” the object of which was to enable the subject to “live differently, better, more happily, than other people” (AB 210, 205). Judith Butler captures the gravity of the shift: “In the last years of his life, Foucault returned to the question of confession, reversing his earlier critique in the first volume of the History of Sexuality, where he indicts confession as a forcible extraction of sexual truth, a practice in the service of a regulatory power” (2005, 112).This reversal was short lived. Although Foucault would celebrate ancient Greek techniques of the self for the rest of his life, he would not [End Page 95] long refer to these techniques in terms of confession. Thus, in another reading of De ira, this one in March 1982, Foucault again noted that the Stoics have “confessional practices” that are “very close to what is found in Christianity” (Herm 482). This time, however, he insisted that the Stoic practices were fundamentally different: “However, all these elements seem to me to be profoundly different from what we should call ‘confession’ in the strict, or anyway, spiritual sense of the word” (Herm 365). In The Care of the Self, Foucault again conceded that De ira—what he now called “the most detailed description” of antique practices of the self—looked “at first glance” like a Christian confession, but he again maintained that it is something quite different: “The purpose of the examination is not therefore to discover one’s own guilt, down to its most trifling forms” (CS 61–62). Foucault concluded that the various “discourses of the self”—the confession and the Greek techniques of the self—could not be placed into a single category (see GE 250). Indeed, the “profound difference” (Herm 299) between these two discourses of the self was perhaps Foucault’s most repeated claim of the 1980s (see Herm 222, 237–44, 299, 308; GE 247–48; WS 237; AB 207–8; RFT 27; UP 89; CS 239; SS 5; FI 5, 12; FS 30, 35, 44, 87, 96, 97, 143–45, 147).It is worth asking why Foucault returned so consistently to the distinction between these two discursive forms. This question gains even more relevance for readers of this journal when we remember that, on at least two occasions, Foucault defined one of these forms, the ancient techniques of the self, in terms of its opposition to rhetoric: the techniques of the self, he claimed, are “nonrhetorical” (Herm 368; FS 20). Thus the question that drives this essay is not so much why Foucault attached such importance to the distinction but rather how rhetoric itself might differentiate the confession from the techniques of the self. Stated differently, Foucault’s work on the confession vis-à-vis the technologies of the self provides a valuable opportunity to study the role of rhetoric in Foucault’s thought—not because they are both rhetorical forms but, curiously, because Foucault insists that one is not.In order to foreground the work of rhetoric in Foucault’s thought, I situate his discourses of the self in the context of Nietzsche’s critique of metonymy. Although this may seem arbitrary, it gains initial plausibility from three facts. First, we know that Foucault understood rhetoric in terms of tropes (OT 84; Cooper 1988, 4). Second, we know too that Foucault had a deep... (shrink)

In early 2021, a Canadian investigation revealed the discovery of over a thousand grave sites of indigenous children on the grounds of Indian residential schools across Canada. These discoveries prompted US Secretary of the Interior Deb Haaland to announce a similar investigation into the ongoing legacy and intergenerational impact of federally sponsored Indian boarding schools in the United States. In addition to documenting the legacy of abuse, neglect and dominance of indigenous peoples, we believe that such reflection upon the impact (...) of Indian boarding schools should also include the justifications that were used to promote the government policy of compelling indigenous children to leave family, tribe, customs and even language behind to be acculturated in remote boarding schools far from home or reservation. For while in hindsight these policies can be both deplored and regretted, they were not crafted in a philosophical vacuum. Specifically, it might come as a surprise to scholars today that Hegelian thought actually featured in the support and promotion of such policies. We propose to tell at least part of this story, by focusing on the leading American Hegelian of the time, William Torrey Harris, who—as director of the famed Concord School of Philosophy and also longtime US Commissioner of Education—was highly influential in both philosophical and educational circles. In that latter capacity, Harris penned a defence of the boarding school system, which drew upon broadly Hegelian ideas and language. So while we have elsewhere defended and lauded Harris and the St Louis Hegelians for their contributions to American philosophy and democratic educational thought, here is one respect in which this influence has not stood up well to the test of time.

Traditional health sciences (including nursing) paradigms, conceptual models, and theories have relied heavily upon notions of the ‘person’ or ‘patient’ that are deeply rooted in humanistic principles. Our intention here, as a collective academic assemblage, is to question taken‐for‐granted definitions and assumptions of the ‘person’ from a critical posthumanist perspective. To do so, the cinematic works of filmmaker David Cronenberg offer a radical perspective to revisit our understanding of the ‘person’ in nursing and beyond. Cronenberg's work explores bodily transformation and (...) mutation, with the body as a fragile and malleable vessel. Cronenberg's work allows us to interrogate the body in all its complexity, contingency, and hybridity and provides avenues of rupture within current understandings of ‘the person’. Reinventing the definition of what it means to be human, critical posthumanism offers opportunities to both critique humanist theories and build affirmative futurities. Also drawing on the work of Deleuze and Guattari, specifically, their concept of becoming, we propose a critical posthumanist alternative to the conceptualization of the person in the health sciences, that of the becoming‐mutant, so frequently explored in Cronenberg's films. Such a conceptualization permits the inclusion of various technological interventions of the contemporary subject: The postperson. This position offers the health science disciplines a radical reconceptualization of the conceptual and theoretical approaches, extending beyond those trapped within the quagmire of humanistic principles.

It has been invoked to help explain the development and retention of, amongst others, RNA splicing, RNA editing and ribosomal and mitochondrial respiratory chain complexity.

Here I contend, that in its extended form, it has major conceptual problems, can not explain observed (...) patterns of complex processes, is too easily dismissive of alternative selectionist models, underestimates the creative force of complexity as such, and – if seen as a major evolutionary mechanism for all organisms – could stifle further thought regarding the evolution of highly complex biological processes.

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.

Susan Hurley (1998a, 2003a, 2008) argues that our capacities for perception, agency and thought are essentially interdependent and co-emerge from a tangle of sensorimotor processes that are both cause and effect of the web of interactive and communicative practices they weave us into. In this paper, I reconstruct this view and its main motivations, with a particular focus on three important aspects. First, Hurley argues that an essential aspect of conscious perception – its perspectival unity – constitutively depends on agency. (...) That is, agency is a transcendental condition on the possibility of perception (§3). Second, understanding why this dependence obtains involves understanding why perception and agency emerge together, and how they do so on the basis of a web of interrelated capacities for sensorimotor control (§2, §4). Third, understanding these first two aspects of Hurley’s view is the key to understanding the sophisticated interplay between i) her arguments for the causal interdependence of sensory input and motor output, and ii) her arguments for the essential interdependence of perception and agency.

Recently, a review regarding the mechanics and evolution of mitochondrial fission appeared in Nature. Surprisingly, it stated authoritatively that the mitochondrial outer membrane, in contrast with the inner membrane of bacterial descent, was acquired from the host, presumably during uptake. However, it has been known for quite some time that this membrane was also derived from the Gram‐negative, alpha‐proteobacterium related precursor of present‐day mitochondria. The zombie idea of the host membrane still surrounding the endosymbiont is not only wrong, but more (...) importantly, might hamper the proper conception of possible scenarios of eukaryogenesis. Why? Because it steers the imagination not only with regard to possible uptake mechanisms, but also regarding what went on before. Here I critically discuss both the evidence for the continuity of the bacterial outer membrane, the reasons for the persistence of the erroneous host membrane hypothesis and the wider implications of these misconceptions for the ideas regarding events occurring during the first steps towards the evolution of the eukaryotes and later major eukaryotic differentiations. I will also highlight some of the latest insights regarding different instances of endosymbiont evolution. (shrink)

Background The field of personal health monitoring (PHM) develops rapidly in different contexts, including the armed forces. Understanding the ethical dimension of this type of monitoring is key to a morally responsible development, implementation and usage of PHM within the armed forces. Research on the ethics of PHM has primarily been carried out in civilian settings, while the ethical dimension of PHM in the armed forces remains understudied. Yet, PHM of military personnel by design takes place in a different setting (...) than PHM of civilians, because of their tasks and the context in which they operate. This case study therefore focusses on obtaining insights into the experiences and related values of different stakeholders regarding an existing form of PHM, the Covid-19 Radar app, in the Netherlands Armed Forces. Methods We carried out an exploratory qualitative study, using semi-structured interviews with twelve stakeholders in the Netherlands Armed Forces. We focussed on participation in the use of PHM, reflections on the practical use and use of data, moral dilemmas and the need for ethics support, all in regard to PHM. The data was analysed using an inductive thematic approach. Results Three interlinking categories reflecting ethical dimensions of PHM emerged: (1) values, (2) moral dilemmas, and (3) external norms. The main values identified were: security (in relation to data), trust and hierarchy. Multiple related values were found. Some, but no broadly shared, moral dilemmas were identified and no strong need for ethics support was expressed. Conclusion This study shed light on key values, provide insights in the experienced and presumed moral dilemmas and bring to mind ethics support considerations when looking at PHM in the armed forces. Some values bring a certain vulnerability to military users when personal and organisational interests are not aligned. Furthermore, some identified values may hinder a careful consideration of PHM because they potentially conceal parts of ethical dimensions of PHM. Ethics support can assist in uncovering and addressing these concealed parts. The findings highlight a moral responsibility for the armed forces to devote attention to the ethical dimensions of PHM.

Darwinian evolution can be simply stated: natural selection of inherited variations increasing differential reproduction. However, formulated thus, links with biochemistry, cell biology, ecology, and population dynamics remain unclear. To understand interactive contributions of chance and selection, higher levels of biological organization (e.g., endosymbiosis), complexities of competing selection forces, and emerging biological novelties (such as eukaryotes or meiotic sex), we must analyze actual examples. Focusing on mitochondria, I will illuminate how biology makes sense of life's evolution, and the concepts involved. First, (...) looking at the bacterium – mitochondrion transition: merging with an archaeon, it lost its independence, but played a decisive role in eukaryogenesis, as an extremely efficient aerobic ATP generator and internal ROS source. Second, surveying later mitochondrion adaptations and diversifications illustrates concepts such as constructive neutral evolution, dynamic interactions between endosymbionts and hosts, the contingency of life histories, and metabolic reprogramming. Without oxygen, mitochondria disappear; with (intermittent) oxygen diversification occurs in highly complex ways, especially upon (temporary) phototrophic substrate supply. These expositions show the Darwinian model to be a highly fruitful paradigm. (shrink)

What is it to be an agent? One influential line of thought, endorsed by G. E. M. Anscombe and David Velleman, among others, holds that agency depends on practical rationality—the ability to act for reasons, rather than being merely moved by causes. Over the past 25 years, Velleman has argued compellingly for a distinctive view of agency and the practical rationality with which he associates it. On Velleman’s conception, being an agent consists in having the capacity to be motivated by (...) a drive to act for reasons. Your bodily movements qualify as genuine actions insofar as they are motivated in part by your desire to behave in a way that makes sense to yourself. However, there are at least two distinct ways of spelling out what this drive towards self-intelligibility consists in, both present in Velleman’s work. It might consist in a drive towards intelligibility in causal-psychological terms: roughly, a drive to maximize the rational coherence of your psychological states. Alternatively, it might consist in a drive towards narrative intelligibility: a drive to make your ongoing activity conform to a recognizable narrative structure, where that structure is understood emotionally. Velleman originally saw these options as basically equivalent, but later came to prioritize the drive towards causal-psychological intelligibility over that towards narrative intelligibility. I argue that this gets things the wrong way round—we should instead understand our capacities to render ourselves intelligible in causal-psychological terms as built upon a bedrock of emotionally suffused narrative understanding. In doing so, we resolve several problems for Velleman’s view, and pave the way for an embodied, embedded and affective account of practical rationality and agency. According to the picture that emerges, practical rationality is essential to agency, narrative understanding is essential to practical rationality, and the rhythms and structures patterning the ebb and flow of our emotional lives are essential to narrative understanding.
