This paper discusses the possibility of an absolute vacuum - a space without any substance. The motivation of this study is the contrast between most philosophers, up to Descartes, who stated that a vacuum was impossible, and the 17th century change of outlook, when the possibility and effective existence of the vacuum was accepted after the experiments of Torricelli and Pascal. This article attempts to show that, contrary to the received opinion, the acceptance of an ether is preferable to the (...) acceptance of a vacuum for several reasons. First: it is impossible to provide an empirical proof of the non-existence of the ether; second, an absolute vacuum is unthinkable; third, the ether concept is useful for the understanding of physical phaenomena; and fourth, the hypothesis of an ether in apparently void spaces is useful for the future development of science. The paper also endeavours to show that no recent advance of science changed those conclusions and that no future development can change them. (shrink)

Dans cet article nous étudions le Trattato della sfera de Galilée, écrit avant 1600. C’est un traité d’astronomie géocentrique qui suit la structure du Tractatus de sphæra de Johannes de Sacrobosco. Nous analysons quelques particularités du traité, en le comparant à d’autres travaux astronomiques du xvie siècle, et nous discutons ses sources probables. Nous soutenons que l’influence du commentaire de Christoph Clavius sur la Sphæra de Sacrobosco ne peut pas être considérée comme son influence unique ou principale. Le traité de (...) Galilée était probablement inspiré par la Sfera del mondo de Piccolomini, un travail qui anticipait plusieurs particularités du Trattato della sfera. Cette influence est établie par de nombreuses annotations de Galilée trouvées dans un exemplaire du livre de Piccolomini. (shrink)

Background As more people are living longer, they become frail and are affected by multi-morbidity, resulting in increased demands from the ambulance service. Being vulnerable, older patients may have reduced decision-making capacity, despite still wanting to be involved in decision-making about their care. Their needs may be complex and difficult to assess, and do not always correspond with ambulance assessment protocols. When needing an ambulance, older patients encounter ambulance clinicians who are under high workloads and primarily consider themselves as emergency (...) medical care providers. This situates them in the struggle between differing expectations, and ethical conflicts may arise. To resolve these, providing ethical care, focussing on interpersonal relationships and using ethical competence is needed. However, it is not known whether ambulance clinicians possess the ethical competence required to provide ethical care. Thus, the aim of this study was to deductively explore their ethical competence when caring for older patients with reduced decision-making ability. Methods A qualitative deductive and exploratory design was used to analyse dyadic interviews with ambulance clinicians. A literature review, defining ethical competence as comprising ethical sensitivity, ethical knowledge, ethical reflection, ethical decision-making, ethical action and ethical behaviour, was used as a structured categorization matrix for the analysis. Results Ambulance clinicians possess ethical competence in terms of their ethical knowledge, highlighting the need for establishing an interpersonal relationship with the older patients. To establish this, they use ethical sensitivity to interpret the patients’ needs. Doing this, they are aware of their ethical behaviour, signifying how they must act respectfully and provide the necessary time for listening and interacting. Conclusions Ambulance clinicians fail to see their gut feeling as a professional ethical competence, which might hinder them from reacting to unethical ways of working. Further, they lack ethical reflection regarding the benefits and disadvantages of paternalism, which reduces their ability to perform ethical decision-making. Moreover, their ethical knowledge is hampered by an ageist approach to older patients, which also has consequences for their ethical action. Finally, ambulance clinicians show deficiencies regarding their ethical reflections, as they reflect merely on their own actions, rather than on their values. (shrink)

Drawing upon the literature on action research and case-study research, this paper discusses similarities and differences between these two forms of research practice. The paper also highlights some of the criticisms and challenges action researchers face. It suggests ways in which action researchers may enhance the discussability of action research by: (a) increasing the transparency of their research processes, (b) declaring the intellectual frameworks brought into action research projects, (c) discussing transferability of findings, and (d) defining accumulation of results. This (...) may require an extension to scientific discourse. In particular, the paper suggests that action researchers could change the ways in which action research results are reported to increase their reach among a wider audience. (shrink)

We describe our clinical experience in treating patients with Tourette syndrome and other tic disorders using infra-low frequency neurofeedback, often in conjunction with cognitive behavior therapy. Following a narrative description of our approach, we present outcome data for 100 successive cases. Many of the children and adolescents that we have treated since 2005 did not derive sufficient benefit from standard treatment for Tourette syndrome and other tic disorders. In our clinical experience, based on extensive before- and after- testing and symptom (...) tracking, this patient group derived significant additive benefit from complementary neurofeedback treatment. The majority of trainees attained a higher level of functioning and were able to live up to their potential in a way they were not able to prior to neurofeedback treatment. (shrink)

Background:Many frail older persons who die in Swedish nursing homes need assisted bodily care. They must surrender their bodies to the authority of assistant nurses, which may affect their autonomy and dignity of identity. While assistant nurses claim to support older persons’ wishes, older persons claim they have to adapt to assistant nurses' routines. The provider–receiver incongruence revealed here warrants investigation.Aim:To describe the elements of assisted bodily care, as performed in a nursing home.Research design:Data were collected through thirty-nine observations of (...) assisted bodily care, analyzed with qualitative content analysis.Participants and research context:Seventeen older persons and twenty-two assistant nurses from a Swedish nursing home.Ethical considerations:The research was conducted in line with the Declaration of Helsinki, further approved by the regional ethics committee.Findings:Findings show that assisted bodily care consists of assistant nurses’ practical work, performed at a high tempo. Assistant nurses still attempt to adapt this work to the older persons’ wishes for self-determination, taking into account their day-to-day state of health. In spite of time pressure and occasional interruptions, there is room for consideration and affection in assisted bodily care.Discussion:Assistant nurses try to promote older persons’ dignity of identity, but sometimes fail, possibly due to lack of time. They nevertheless seem to know the older persons well enough to adapt the assisted bodily care according to their preferences and to support self-determination. This indicates that openness to older persons’ lifeworlds may be more important than the amount of time available.Conclusion:Nursing home contexts might benefit from adopting a person-centered palliative care perspective, highlighting the value of relationships and shared decision-making. If so, older persons and assisted nurses could agree on practices and goals in assisted bodily care beforehand. Such routines may be time-saving and beneficial to all. (shrink)

Background: Worldwide, older persons lack access to palliative care. In Sweden, many older persons die in nursing homes where care is provided foremost by assistant nurses. Due to a lack of beds, admission is seldom granted until the older persons have complex care needs and are already in a palliative phase when they move in. Objective: To describe assistant nurses’ perspectives of providing care to older persons at the end of life in a nursing home. Research design: Data were collected (...) in semi-structured individual interviews and analyzed with inductive qualitative content analysis. Participants and research context: Seven assistant nurses from a nursing home in Sweden were randomly selected. Ethical consideration: The research was approved by the local ethics committee. Results: Three main categories emerged; “Death a natural part of life”; “The older person’s well-being”; and “Care in the moment of death”; and seven sub-categories. The assistant nurses described themselves as knowing the older persons well enough to provide good end-of-life care. This was achieved by making small-talk while providing daily care. Relying on experience-based knowledge, they strove to provide end-of-life care built upon respect and engagement with the ambition to strengthen older persons’ dignity, for example, by lowering the tempo of care at the end of life, in spite of organizational restrictions. Discussion: The assistant nurses offered attentive end-of-life care, focusing upon bodily care. The existential needs of the older persons were not foregrounded. Conclusion: To develop their work, and to promote an ethical foundation for such care, assistant nurses might need support and education to be able to offer a care more in line with the aims of palliative care. Furthermore, the organization of care needs to promote, not impede, the realization of this development. (shrink)

For us, narrative care is grounded in pragmatist philosophy and focused on experience. Narrative care is not merely about acknowledging or listening to people's experiences, but draws attention to practical consequences. We conceptualize care itself as an intrinsically narrative endeavour. In this article, we build on Lugones' understanding of playfulness, particularly to her call to remain attentive to a sense of uncertainty, and an openness to surprise. Playfulness cultivates a generative sense of curiosity that relies on a close attentiveness not (...) only to the other, but to who we each are within relational spaces. Generative curiosity is only possible if we remain playful as we engage and think with experiences and if we remain responsive to the other. Through playfulness, we resist dominant narratives and hold open relational spaces that create opportunities of retelling and reliving our experiences. Drawing on our work alongside older adults, as well as people who work in long‐term care, we show the possibilities of playfulness in the co‐composition of stories across time. By intentionally integrating playfulness, narrative care can be seen as an intervention, as well as a human activity, across diverse social contexts, places and times. (shrink)

Michael Walzer’s article ‘Political action: the problem of dirty hands’ initiated a new wave of discussion over a persistent problem in moral philosophy: are there situations in which ethical rules must be relaxed so as to bring about a greater good? In this article, we consider whether this ‘dirty hands’ approach may be applied to our current climate crisis. One proposed solution to the problem of global warming is the administration of moral enhancements to the population. Assuming that the administration (...) of moral enhancements is a necessary condition in the prevention of a climate crisis, Parker Crutchfield argues that this procedure ought to be covert. This implies lying to the public, and such dishonesty amounts to immoral behavior. We conclude that despite the severity of global warming, there is no justification for a dirty hands approach. Lying to the public in order to save the planet would probably create bigger problems, and it would ultimately be very counterproductive in trying to save the planet. (shrink)

This article takes its point of departure in a research project studying the psychosocial problems of living with HIV. The project was intended to participate in changing practices dealing with these problems. It became a project including many differently situated and intersecting personal and generalized perspectives. The article researches the development of the HIV project as a contribution to discussions related to Participatory Action Research and Practice Research. In mainstream approaches methodological indications are often presented as rules to follow in (...) order to ensure the quality of the obtained knowledge. But situated historical and societal processes are involved in the effectuation of the HIV project, like they are in any other project. Researching the project heightens the awareness of the necessity of reflecting on situated and historical issues of power and marginalization and on the positions of the researcher in a given field of research. Methodological flexibility may also be necessary in order to encompass different perspectives. Such reflections and strategies are necessary precisely to ensure the development of knowledge and practice alike. (shrink)

When Gödel developed his functional interpretation, also known as the Dialectica interpretation, his aim was to prove consistency of first order arithmetic by reducing it to a quantifier-free theory with finite types. Like other functional interpretations Gödel’s Dialectica interpretation gives rise to category theoretic constructions that serve both as new models for logic and semantics and as tools for analysing and understanding various aspects of the Dialectica interpretation itself. Gödel’s Dialectica interpretation gives rise to the Dialectica categories , in: Contemp. (...) Math., vol. 92, Amer. Math. Soc., Providence, RI, 1989, pp. 47–62] and J.M.E. Hyland in [J.M.E. Hyland, Proof theory in the abstract, Ann. Pure Appl. Logic 114 43–78, Commemorative Symposium Dedicated to Anne S. Troelstra ]). These categories are symmetric monoidal closed and have finite products and weak coproducts, but they are not Cartesian closed in general. We give an analysis of how to obtain weakly Cartesian closed and Cartesian closed Dialectica categories, and we also reflect on what the analysis might tell us about the Dialectica interpretation.

While some countries are moving toward legalization, euthanasia is still criticized on various fronts. Most importantly, it is considered a violation of the medical ethics principle of non-maleficence, because it actively seeks a patient’s death. But, medical ethicists should consider an ethical alternative to euthanasia. In this article, we defend cryocide as one such alternative. Under this procedure, with the consent of terminally-ill patients, their clinical death is induced, in order to prevent the further advance of their brain’s deterioration. Their (...) body is then cryogenically preserved, in the hope that in the future, there will be a technology to reanimate it. This prospect is ethically distinct from euthanasia if a different criterion of death is assumed. In the information-theoretic criterion of death, a person is not considered dead when brain and cardiopulmonary functions cease, but rather, when information constituting psychology and memory is lost.

This article studies the mathematical properties of two systems that model Aristotle's original syllogistic and the relationship obtaining between them. These systems are Corcoran's natural deduction syllogistic and ?ukasiewicz's axiomatization of the syllogistic. We show that by translating the former into a first-order theory, which we call T RD, we can establish a precise relationship between the two systems. We prove within the framework of first-order logic a number of logical properties about T RD that bear upon the same properties (...) of the natural deduction counterpart ? that is, Corcoran's system. Moreover, the first-order logic framework that we work with allows us to understand how complicated the semantics of the syllogistic is in providing us with examples of bizarre, unexpected interpretations of the syllogistic rules. Finally, we provide a first attempt at finding the structure of that semantics, reducing the search to the characterization of the class of models of T RD. (shrink)

Abstract This paper describes the early history of magnetochemistry: the search for chemical effects of magnetism in the nineteenth century. Some early researchers, such as Johann Wilhelm Ritter, attempted to reproduce with magnets the effects that had been produced by electricity and Volta’s battery. For several decades, researchers successively reported positive results and denied claims concerning the effect of magnetism in oxidation, electrolysis, reduction of metals from saline solutions, crystallisation, change of colour of vegetable tinctures and other chemical reactions. In (...) the two last decades of the nineteenth century some effects were accepted as real, and a thermodynamic theory of the influence of magnetic fields upon chemical reactions was developed. Finally, Dragomir Hurmuzescu was able to create reproducible experiments and measured the electromotive force between two electrodes, with or without the presence of magnetic fields, confirming the existence of the phenomenon and obtaining results compatible with the theoretical predictions. Afterwards, this magnetochemical effect was accepted as real, but the effect was weak and its practical importance was negligible. The subject was gradually forgotten.

This paper discusses the ways in which anesthetic agents can be used to investigate the role of awareness in learning and memory. It reviews research into learning during light, subclinical anesthesia, termedhypesthesia.This research suggests that the effects of anesthetics on implicit and explicit memory are roughly comparable, although implicit memory for simple stimuli may resist the effects of very low doses of anesthetic. In addition, this paper reports experimental data demonstrating that long-term retention of information is prevented by doses of (...) anesthetic that are low enough to permit awareness and even short-term memory of auditory stimuli. Overall, these findings are consistent with the hypothesis that frontal lobe function is particularly sensitive to anesthetics. They raise theoretical and practical questions about the necessity of consciousness for learning and about interpretation of the evidence for learning during surgery under general anesthesia.

Immortality is the indefinite continuation of a person’s existence, even after death. In common parlance, immortality is virtually indistinguishable from afterlife, but philosophically speaking, they are not identical. Afterlife is the continuation of existence after death, regardless of whether or not that continuation is indefinite. Immortality implies a never-ending existence, regardless of whether or not the body dies (as a matter of fact, some hypothetical medical technologies offer the prospect of a bodily immortality, but not an afterlife). Immortality has been (...) one of mankind’s major concerns, and even though it has been traditionally mainly confined to religious traditions, it is also important to philosophy. Although a wide variety of cultures have believed in some sort of immortality, such beliefs may be reduced to basically three non-exclusive models: (1) the survival of the astral body resembling the physical body; (2) the immortality of the immaterial soul (that is an incorporeal existence); (3) resurrection of the body (or re-embodiment, in case the resurrected person does not keep the same body as at the moment of death). This article examines philosophical arguments for and against the prospect of immortality. A substantial part of the discussion on immortality touches upon the fundamental question in the philosophy of mind: do souls exist? Dualists believe souls do exist and survive the death of the body; materialists believe mental activity is nothing but cerebral activity and thus death brings the total end of a person’s existence. However, some immortalists believe that, even if immortal souls do not exist, immortality may still be achieved through resurrection. Discussions on immortality are also intimately related to discussions of personal identity because any account of immortality must address how the dead person could be identical to the original person that once lived. Traditionally, philosophers have considered three main criteria for personal identity: the soul criterion , the body criterion and the psychological criterion. Although empirical science has little to offer here, the field of parapsychology has attempted to offer empirical evidence in favor of an afterlife. More recently, secular futurists envision technologies that may suspend death indefinitely (such as Strategies for Engineered Negligible Senescence, and mind uploading), thus offering a prospect for a sort of bodily immortality.

There is a death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29-year-olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them. Facebook is in a unique position—through its support for networks and friendships on the site—to help connect a person in these difficult situations with people who can support them. Connecting people with the resources (...) they need is part of Facebook’s ongoing efforts to help build a safe community inside and outside of Facebook. This article provides a brief overview of how Facebook’s work to develop suicide prevention tools started and evolved, and the ethical considerations which surfaced during the process in the form of concrete product decisions around the implementation of these tools. This article is structured into three sections. Section 1 reviews what has been done in this space and lists and briefly describes other suicide prevention apps and tools. Section 2 describes Facebook’s overall approach to suicide prevention. Here, we’ll delve first into how that approach originated and how it was influenced by the external community’s proactive interactions with Facebook, highlighting our unique position to help address the problem. Afterwards, we’ll explain how that approach evolved, describing its various stages and iterations: understanding, reactive reporting, queue prioritization, and proactive reporting. This section describes the tools and resources Facebook has developed for people who may be at risk. Particular attention is devoted to the use of ArtificiaI Intelligence and Machine Learning to detect posts or live videos where someone might be expressing thoughts of suicide. Section 3 will elaborate on the ethical questions addressed when developing our approach and when making concrete product decisions to implement our suicide prevention tools. In this last section, we’ll expound the competing values and interests that were at stake during the product development process, and how we reached ethical balances between them. (shrink)

Isometry hypotheses are propositions that assert the constancy of a specific physical magnitude of a system under prescribed conditions. This paper addresses the controversy concerning the conventionality of this type of hypotheses. It discusses several instances of isometry hypotheses and it is shown that experimental facts can be invoked to criticise (or "refute") isometry hypotheses, just as other types of hypotheses. This proves that isometry hypotheses, and the choices of measurement standards that are grounded in such hypotheses, are not merely (...) conventional. (shrink)

This paper defends an internalist perspective of selection based on the hypothesis that considers living evolutionary units as Maxwell's demons (MD) or Zurek's Information Gathering and Using Systems (IGUS). Individuals are considered as IGUS that extract work by means of measuring and recording processes. Interactions or measurements convert uncertainty about the environment (Shannon's information, H) into internalized information in the form of a compressed record (Chaitin's algorithmic complexity, K). The requirements of the model and the limitations inherent to its formalization (...) are discussed. This approach offers an alternative view to the causes of evolutionary variations which goes beyond the classical Lamarckian-Darwinian controversy. I argue that random variations only apply near-to-equilibrium at the time organisms have attained structural closure, and that a speed up of mutation rates that facilitates the production of directed variations occurs far-from-equilibrium due to organisms' openness to the surrounding conditions. However, real organisms are located somewhere between the above two cases and thus, operate at an intermediate stage where there is a maximum efficiency of H/K conversion. In consequence, IGUS keep their autonomy and evolving capacity by compromising between external circumstances and inner constraints. This compromise is made possible by closure regulation. Likewise, this model explains why nature has favored the selection of agents capable of selectively recording a partial description of their environment. (shrink)

In Theory Z-style management everybody participates in corporate decision making. This more open process should give us fewer Pintos, Love Canals, and massive international payoffs as executives are forced to expose their reasoning to the moral sensibilities of the whole corporation. So far everything looks good. But we are a long way from showing that only corporations so managed can be fully moral. Yet Dwiggins seems to believe this, putting his faith in the basic goodness of the many while virtually (...) dismissing the managers as mere technicians. This is too slick; even if it describes our average corporation today, there are plenty of less radical changes which can also produce the desired moral corporation. Good leadership which acts on their commitment to improve the company is surely one historically respectable alternative; cynicism about the present crop of leaders should not distract us from investigating this route. Finally, I wonder if Dwiggins can consistently urge us to embrace a full-scale Theory Z organizational structure, given his position on the place of ethics and profitability. (shrink)

Occupational health remains neglected in developing countries because of competing social, economic and political challenges. Ethical issues in the workplace related to the hazards and risks of becoming infected by Leishmania (Leishmania) mexicana, through the bite of naturally infected sand flies, is another area of concern that has been neglected as well. We report here the results of reviewing two entomological field studies carried out in our research center from 2003 to 2006. Eight students from our School of Biology were (...) invited to catch sand flies. A total of six of the eight (75%) developed a typical clinical picture of Localized Cutaneous Leishmaniasis (LCL) caused by L. (L.) mexicana. In this article we identify the ethical issues related to these kinds of studies and propose some guidelines for conducting them. (shrink)
