Our goal is to show how science fiction films have dealt with the augmentation of bodily and cognitive faculties. These cinematographic imaginaries allow us to question the interest of such innovations. They depict a world in which the artificialization and mechanization of many activities leads to a loss of control over them. This would mean that we would run the risk, in the long term, of being deprived of our human qualities. However, we will show that these films do not (...) question the viability of this type of society. Indeed, these fictions do not insist on the constraints that these transformations nevertheless impose on the environment. Faced with the ecological crisis, the hold of technological innovations on all societies, far from appearing as the solution, risks on the contrary being identified as part of the problem. (shrink)

The paper aims to show how the Tv series True Detective (season 1, 2014 – created and written by Nic Pizzolatto) aids us understanding the status of power whether in its political, judicial or religious form. The conjunction of sex and death is depicted through acts of paedophilia, rape, and murder of women and children. The study aims to elucidate the logic which is inherent to those acts of violence and which founds the reproduction of social domination mechanisms.

The visual arts have managed to make the zombie an essential figure in popular culture. The cinematographic medium has contributed to building with him an imaginary of disaster against the backdrop of a pandemic. We will show the adequacy of the zombie with a collective imagination for which the world to come is inscribed under the sign of zombie collapse.

The informed consent process presents challenges for psychological trauma research (e.g. Institutional Review Board [IRB] apprehension). While previous research documents researcher and IRB-member perspectives on these challenges, participant views remain absent. Thus, using a mixed-methods approach, we investigated participant views on consent guidelines in two convenience samples: crowdsourced (N = 268) and undergraduate (N = 265) participants. We also examined whether trauma-exposure influenced participant views. Overall, participants were satisfied with current guidelines, providing minor feedback and ethical reminders for researchers. Moreover, (...) participant views for consent were similar irrespective of trauma-exposure. Our study has implications for IRBs and psychological researchers. (shrink)

Many historical studies have been devoted to the French school of molecular biology, in particular to the work of Jacques Monod on adaptive enzymes. By focusing on Francois Jacob's studies on lysogeny between 1950 and 1960, we intend to redress the imbalance of historiography, as well as proposing a more fruitful point of view for understanding the relative importance of international contacts and local traditions in the genesis of the operon model.Elie Wollman and Jacob's work on temperate bacteriophages rendered respectable (...) a system that had been considered an artefact for more than two decades. They did this firstly by modelling their studies on those of the US phage group and secondly by basing these studies on a complex vision of the relations between bacteria and bacteriophages. The interaction between bacteria and temperate bacteriophages was considered ab initio as a biochemical process, the mechanisms of which would eventually be characterized. It was also considered as a ''normal'' phenomenon that could be used as a model to understand the process of differentiation, as well as the role of viruses in diseases and cancer. The temperate bacteriophage was a model system that was far more epistemologically open and, for this reason, in a sense more productive than the virulent phage studied by the US phage group.

While philosophers have worried about mental causation for centuries, worries about the causal relevance of conscious phenomena are also increasingly featuring in neuroscientific literature. Neuroscientists have regarded the threat of epiphenomenalism as interesting primarily because they have supposed that it entails free will scepticism. However, the steps that get us from a premise about the causal irrelevance of conscious phenomena to a conclusion about free will are not entirely clear. In fact, if we examine popular philosophical accounts of free will, (...) we find, for the most part, nothing to suggest that free will is inconsistent with the presence of unconscious neural precursors to choices. It is only if we adopt highly non-naturalistic assumptions about the mind (e.g. if we embrace Cartesian dualism and locate free choice in the non-physical realm) that it seems plausible to suppose that the neuroscientific data generates a threat to free will.

Background The worldwide increase in older persons demands technological solutions to combat the shortage of caregiving and to enable aging in place. Smart home health technologies (SHHTs) are promoted and implemented as a possible solution from an economic and practical perspective. However, ethical considerations are equally important and need to be investigated. Methods We conducted a systematic review according to the PRISMA guidelines to investigate if and how ethical questions are discussed in the field of SHHTs in caregiving for older (...) persons. Results 156 peer-reviewed articles published in English, German and French were retrieved and analyzed across 10 electronic databases. Using narrative analysis, 7 ethical categories were mapped: privacy, autonomy, responsibility, human vs. artificial interactions, trust, ageism and stigma, and other concerns. Conclusion The findings of our systematic review show the (lack of) ethical consideration when it comes to the development and implementation of SHHTs for older persons. Our analysis is useful to promote careful ethical consideration when carrying out technology development, research and deployment to care for older persons. Registration We registered our systematic review in the PROSPERO network under CRD42021248543. (shrink)

This paper develops an account of the German discourse particle denn that captures the meaning contribution of this particle in polar questions, wh-questions, and certain conditional antecedents in a unified way. It is shown that the behavior of denn exhibits an asymmetry between polar and wh-interrogatives, which can be captured by treating the particle as sensitive to the property highlighted by its containing clause, in the sense of Roelofsen and Farkas :359–414, 2015). In addition, the paper argues that highlighting-sensitivity should (...) be incorporated in the account of another discourse particle, German überhaupt, and discusses how the proposed account of discourse particle denn may be extended to also cover the use of denn as a causal conjunction.

Controversies in food and agriculture abound, with many portrayed as conflicts between polarized viewpoints. Framing such controversies as dichotomies, however, can at times obscure what might be a plurality of views and potential common ground on the subject. We used Q methodology to explore stakeholders’ views about pesticide safety, agricultural worker exposure, and human health concerns in the tree fruit industry of central Washington State. Using a purposive sample of English and Spanish-speaking agricultural workers, industry representatives, state agencies, educators, and (...) advocates, participants sorted 45 statements on pesticide use and perceived human safety risks in the tree fruit industry in 2011. We used PQMethod 2.33 statistical software program to identify viewpoints, based on differences between how participants sorted the statements. The results revealed three distinct viewpoints among 38 sorters that explained 52 percent of the variance. The viewpoints included the: skeptics who expressed concern over the environmental and human health impacts of pesticide use; acceptors who acknowledged inherent risks for using pesticides but saw the risks as known, small and manageable; and incrementalists who prioritized opportunities to introduce human capital and technological improvements to increase agricultural worker safety. We then brought representatives with these different viewpoints together to analyze the results of the Q study, and to brainstorm mutually acceptable improvements to health and safety in tree fruit orchards. In describing and analyzing this case study, we argue that Q methodology can serve as one potentially effective tool for collaborative work, in this case facilitating a process of orchard safety improvements despite perceived stakeholder polarization.

How do the practices of philosophy and film converge in ethical and political theory? Untimely Affects is an ethical and aesthetic interweaving of Deleuzian philosophy and close film analysis to discern how thought persists productively after the horrors of World War II. In the first extensive analysis of Chris Marker and Alain Resnais' films, Nadine Boljkovac draws on concepts and images that interrogate 'what we are now living through', in the words of Klossowski's Nietzsche. Mindful of the seen and (...) unseen 'that quicken the heart', this book of film-philosophy discerns new and deeply ethical life-affirming possibilities through its weave of cine-philosophy. As such, this book speaks directly to essences of cinema, thought and life through creative untimeliness and the idea of the 'ever new'. (shrink)

Supervenient libertarianism maintains that indeterminism may exist at a supervening agency level, consistent with determinism at a subvening physical level. It seems as if this approach has the potential to break the longstanding deadlock in the free will debate, since it concedes to the traditional incompatibilist that agents can only do otherwise if they can do so in their actual circumstances, holding the past and the laws constant, while nonetheless arguing that this ability is compatible with physical determinism. However, we (...) argue that supervenient libertarianism faces some serious problems, and that it fails to break us free from this deadlock within the free will debate. (shrink)

With robots being introduced into caregiving, particularly for older persons, various ethical concerns are raised. Among them is the fear of replacing human caregiving. While ethical concepts like well-being, autonomy, and capabilities are often used to discuss these concerns, this paper brings forth the concept of social dignity to further develop guidelines concerning the use of robots in caregiving. By social dignity, we mean that a person’s perceived dignity changes in response to certain interactions and experiences with other persons. In (...) this paper, we will first present the concept of social dignity, and then identify a niche where robots can be used in caregiving in an ethical manner. Specifically, we will argue that, because some activities of daily living are performed in solitude to maintain dignity, a care recipient will usually prefer robotic assistance instead of human assistance for these activities. Secondly, we will describe how other philosophical concepts, which have been commonly used to judge robotic assistance in caregiving for the elderly so far, such as well-being, autonomy, and capabilities, are less useful in determining whether robotic assistance in caregiving is ethically problematic or not. To conclude, we will argue that social dignity offers an advantage to the other concepts, as it allows to ask the most pressing questions in caregiving. (shrink)

The notion of computation has changed the world more than any previous expressions of knowledge. However, as know-how in its particular algorithmic embodiment, computation is closed to meaning. Therefore, computer-based data processing can only mimic life’s creative aspects, without being creative itself. AI’s current record of accomplishments shows that it automates tasks associated with intelligence, without being intelligent itself. Mistaking the abstract for the concrete has led to the religion of “everything is an output of computation”—even the humankind that conceived (...) the computer. The hypostatized role of computers explains the increased dependence on them. The convergence machine called deep learning is only the most recent form through which the deterministic theology of the machine claims more than what it actually is: extremely effective data processing. A proper understanding of complexity, as well as the need to distinguish between the reactive nature of the artificial and the anticipatory nature of the living are suggested as practical responses to the challenges posed by machine theology.

The artistic work of photographer Gudio Baselgia focuses on landscapes formed by nature s forces and, more recently, on the sky with the stellar and solar movements and phenomena as we see them from earth. Celestial mechanics have fascinated mankind in all known cultures, the Babylonians and ancient Egyptians as well as the Greek and Celts, the Maya, or the ancient Indians and Chinese. Until the present day we look at the sky and keep being amazed, and try to read (...) what it tells us. Many artists throughout history have been captivated by the spectacle we observe above us day and night. The modern term astrodynamics describes all movements of celestial bodies, in particular the solar system including the moon and other satellites, asteroids and comets, but also movements of stars within a stellar system or galaxy, or of galaxies towards each other. They are well understood today and depicted in coordinate systems and elaborate visualizations. Guido Baselgia s artistic project on astrodynamics and celestial phenomena has no scientific or didactic ambition. His analogue camera is used as a recorder inscribing the movement of stars on the light-sensitive surface of photographic paper. Thus Baselgia s images make traceable the trajectory of celestial bodies invisible to the human eye and show us astounding occurrences of light and shadow. Baselgia has been captivated in particular also by the phenomenon of the umbra, planet earth s shadow thrown into space. It becomes visible occasionally on a clear evening at sunset when a slight mist lies at the horizon: looking in opposite direction to the sun, a dark and sharply marked band of shadow can be seen rising while sun sets behind the observer. But also by recording sunrise and sunset at the polar circle or the tropic, Baselgia visualizes the geometry of celestial mechanics and the concurrence of forces, as well as the miracle of light as such that leaves us awestruck today as much as it did our ancestors. The new book "Guido Baselgia Light Fall" presents 80 outstanding black-and-white images from the artist s Light Fall project taken in Norway, the Tierra del Fuego archipelago in Argentina, in Ecuador, and the Swiss Alps. The brilliant tritone plates are complemented with essays by the German scholar Andrea Gnam and Swiss photography critic Nadine Olonetzky. ". (shrink)

For more than twenty years, Swiss photographer Tobias Madörin has been working on his photo series Topos. Creating staged tableaux in the manner of nineteenth-century painters, Madörin investigates the interaction between the inhabitants and their surrounding environments in countries as diverse as Spain, Uganda, Indonesia, and Japan. His large-scale images examine communal spaces, the outskirts of metropolises, waste disposals sites, and landscapes marked by agriculture and mining. Madörin's work reveals that these locations are the products of human visions and ideals, (...) yet they are also places of environmental exploitation. This tension, as well as Madörin's intelligent and empathetic approach to his subjects, makes his photographs evocative and complex. This book includes lavish, full-page photographs, many of which have never been published, and an introductory essay by Nadine Olonetzky that explains and contextualizes the photographer's oeuvre.

A recurrent theme of human–machine interaction is how interaction is defined and what kind of information is relevant for successful communication. In accordance with the theoretical strategies of social cognition and technical philosophy, we propose a pragmatic interactive approach, to understand the concept of information in human–machine interaction. We start with the investigation of interpersonal interaction and human–machine interaction by concerning triangulation as guiding principle. To illustrate human–machine interaction, we will mainly focus on the interactive relationship between human cognitive skills (...) and their technological environments. In triadic interaction, the concept of information cannot only be understood as a syntactic transformation as in the dyadic relationship. We argue that information as pragmatic action patterns can be understood as physically embodied units that is not purely formal but generated in interactive processes and stabilized in use. By exploring how the concept of affordance is applied in psychology, anthropology and human-centered design, we provide a notion of pragmatic information, focusing on users in the development and use of machines or software systems. The triadic interaction of end user, development team, and product leads to a successful human–machine interaction. This theoretical framework enables us to understand how the new socio-technological environments expand our scope of action and how we form, interpret, and learn to deal with patterns of action among ourselves and with machines.

Proponents of modern Frankfurt-Style Counterexamples generally accept that we cannot construct successful FSCs in which there are no alternative possibilities present. But they maintain that we can construct successful FSCs in which there are no morally significant alternatives present and that such examples succeed in breaking any conceptual link between alternative possibilities and free will. I argue that it is not possible to construct an FSC that succeeds even in this weaker sense. In cases where any alternatives are clearly insignificant, (...) it does not appear at all obvious that the agent can be held responsible. Present popular FSCs include alternatives that are ambiguous in their significance, and when the examples are sharpened to remove this ambiguity, they lose their force. Moreover, the proponent of such examples faces a problem: We can easily construct scenarios in which any alternatives are obviously insignificant, and in such scenarios, we are not intuitively inclined to suppose the agent is responsible. The proponent of new FSCs must therefore distinguish any alternatives she includes from the sorts included in these scenarios. The difference must now be such that this helps to make it seem intuitively likely that the agent is responsible where the agent otherwise would not appear responsible, and these alternatives are irrelevant to any judgment about whether the agent is responsible. I maintain that it is impossible to achieve both of these goals at once. (shrink)

Objective: The establishment of patient-centered measures capable of empirically determining meaningful cognitive change after surgery can significantly improve the medical care of epilepsy patients. Thus, this study aimed to develop reliable change indices (RCIs) and standardized regression-based (SRB) change norms for a comprehensive neuropsychological test battery in the German language. Methods: Forty-seven consecutive patients with temporal lobe epilepsy underwent neuropsychological assessments, both before and 12 months after surgery. Practice-effect-adjusted RCIs and SRB change norms for each test score were computed. To (...) assess their usefulness, the presented methods were applied to a clinical sample, and binary logistic regression analyses were conducted to model the odds of achieving improvement in quality of life (QOL) after surgery. Results: The determined RCIs at 90% confidence intervals, and the SRB equations for each test score included in the test battery are provided. Cohen’s kappa analyses revealed a moderate mean agreement between the two measures, varying from slight to almost perfect agreement across test scores. Using these measures, a negative association between improvement in QOL and decline in verbal memory functions after surgery was detected. Significance: To the best of our knowledge, this study is the first to provide RCIs and SRB change norms necessary for the objective determination of neuropsychological change in a comprehensive test battery in the German language, facilitating the individual monitoring of improvement and decline in each patients’ cognitive functioning and psychosocial situations after epilepsy surgery. The application of the described measures revealed a strong negative association between improvement in QOL and decline in verbal memory functions after surgery. (shrink)

A type of transcendental argument for libertarian free will maintains that if acting freely requires the availability of alternative possibilities, and determinism holds, then one is not justified in asserting that there is no free will. More precisely: if an agent A is to be justified in asserting a proposition P (e.g. "there is no free will"), then A must also be able to assert not-P. Thus, if A is unable to assert not-P, due to determinism, then A is not (...) justified in asserting P. While such arguments often appeal to principles with wide appeal, such as the principle that ‘ought’ implies ‘can’, they also require a commitment to principles that seem far less compelling, e.g. the principle that ‘ought’ implies ‘able not to’ or the principle that having an obligation entails being responsible. It is argued here that these further principles are dubious, and that it will be difficult to construct a valid transcendental argument without them. (shrink)

Despite the practical orientation of his profession, the mechanikos was of high social standing. This was possible because the practical utility of a vocation was increasingly acknowledged favourably in late antiquity and is reflected in early Byzantine portrayals of patrons, who allegedly invested hard labour in prestigious building campaigns and posed as the (...) supreme architects.

Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)

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)

Pereboom has formulated a Frankfurt-style counterexample in which an agent is alleged to be responsible despite the fact that there are only non-robust alternatives present (Pereboom, Moral responsibility and alternative possibilities: essays on the importance of alternative possibilities, 2003; Phil Explor 12(2):109–118, 2009). I support Widerker’s objection to Pereboom’s Tax Evasion 2 example (Widerker, J Phil 103(4):163–187, 2006) (which rests on the worry that the agent in this example is derivatively culpable as opposed to directly responsible) against Pereboom’s recent counterarguments (...) to this objection (Pereboom 2009). Building on work by Moya (J Phil 104:475–486, 2007; Critica 43(128):3–26, 2011) and Widerker (Widerker 2006), I argue that there is good reason to measure the robustness of alternatives in terms of comparative, rather than non-comparative likelihood of exemption, where the important factor for blame is whether the agent is “doing her reasonable best” to avoid blameworthy behaviour. I maintain that an agent only ever appears responsible when alternatives are robust in this sense. In Pereboom’s examples, both Tax Evasion 2, and his more recent version, Tax Evasion 3 (Pereboom 2009), I maintain the robustness of the alternatives, so understood, is unclear. We can clear up any ambiguity by sharpening the examples, and the result is that the agent appears responsible when the alternatives are made clearly robust, and does not appear responsible when alternatives appear clearly non-robust. The comparative nature of our judgements about blame, I maintain helps to explain the continuing appeal of the “leeway-incompatibilist” viewpoint. (shrink)

A “contrastive explanation” explains not only why some event A occurred, but why A occurred as opposed to some alternative event B. Some philosophers argue that agents could only be morally responsible for their choices if those choices have contrastive explanations, since they would otherwise be “luck infested”. Assuming that contrastive explanations cannot be offered for causally undetermined events, this requirement entails that no one could be held responsible for a causally undetermined choice. Such arguments challenge incompatibilism, since they entail (...) that causal determinism is a prerequisite for moral responsibility. However, I argue that for a significant class of choices, even if we stipulate that they are determined, we will be unable to provide a relevant contrastive explanation. Hence causal determinism is no remedy for luck infestation, and compatibilists do not fare much better than incompatibilists in the face of this requirement. This should serve to weaken its philosophical appeal. (shrink)

In January 2022 the new Dutch Civic Integration programme was launched together with promises of improvements it would bring in facilitating the ‘integration’ of newcomers to the Netherlands. This study presents a critical discourse analysis of texts intended for municipalities to take on their new coordinating role in this programme. The analysis aims to understand the discourse in the texts, which actors are mobilized by them, and the role these texts and these actors play in processes of governmental racialization. The (...) analysis demonstrates shifting complex assemblages are brought into cascades of governance in which all actors are disciplined to accept the problem of integration as a problem of cultural difference and distance, and then furthermore disciplined to adopt new practices deemed necessary to identify and even ‘objectively’ measure the inherent traits contributing to this problematic. Lastly, the analysis displays that all actors are disciplined to accept the solution of ‘spontaneous compliance’; a series of practices and knowledges, which move the civic integration programme beyond an aim of responsibilization, into a programme of internalization, wherein newcomers are expected to own and address their problematic ‘nature’, making ‘modern’ values their own.

ABSTRACT Agents in Frankfurt-style counterexamples only appear to be responsible insofar as they act willingly in the actual sequence, but would need to be manipulated against their will into forming the relevant intention in the alternative sequence. This difference appears ineliminable and unavoidably morally significant. ‘Neo-Frankfurtians’ concede that the sequences must be physically differentiated, but deny their moral differentiation. In contrast, I explore whether the alternatives could be physically undifferentiated, despite their moral difference. The reason there is an ineliminable moral (...) difference is because there is an ineliminable causal one: The agent’s choice must be caused by his own inclinations in one sequence, but by Black’s manipulation in the other. Whether this causal difference entails a physical one depends on whether we suppose causal relations conform to Humean supervenience. The denial of the latter requires us to either reject any broadly Humean view of causation, or else to suppose that we can individuate events or their qualities independently of the physical facts. If these are coherent possibilities, such examples may show that physically differentiated alternatives are not required for moral responsibility. This could support compatibilism, but only if such examples adequately parallel determinism, and I remain sceptical on this point. (shrink)

Pregnancy is thought to be a metabolically very expensive endeavor, yet investigations have produced inconsistent results concerning the responsiveness of human birth weight to maternal nutritional stress or nutritional intervention. These findings have led some researchers to conclude that fetal growth is strongly buffered against fluctuations in maternal energy balance, making the fetus in effect a “nearly perfect parasite.” This buffering would appear to be a reasonable adaptive response given the high risk of morbidity and mortality associated with low birth (...) weight. However, a life-history approach leads to the prediction that maternal investment strategies in pregnancy should be geared toward maximizing lifetime reproductive success rather than simply the success of the current pregnancy, and by extension that maternal investment strategies should vary with reproductive value. The physiology of human pregnancy in fact appears to include a number of mechanisms that protect maternal energy resources from diversion to the fetus and preserve them for future reproductive events. These mechanisms include adjustment of blood flow to the uterus and perhaps minor adjustments in gestation length, although evidence for the latter is scant. Suggestions are made for ways of investigating these maternal options. (shrink)
