This article analyses the sequential ordering of multi-modal discussions in real-time online classes in postgraduate education contexts. The article explores the ways that text and verbal talk are organized by the participants as inter-connecting modes of interaction. Focusing on Initiation, Response and Feedback sequences as an example of a form of exchange, the article shows that the interaction was comparatively disorderly where conducted across talk and text modes. For instance, written responses to questions or to encouragement turns often overlapped with (...) verbal answers from other students or with encouragement turns from the tutor. However, through the withholding of speech turns, the close latching of speech to written talk, and the ceasing of written turns at points where the topics or speakers changed, the participants showed a concern with re-establishing sequential order across the modalities.

We have synthesized a 582,970-base pair Mycoplasma genitalium genome. This synthetic genome, named M. genitalium JCVI-1.0, contains all the genes of wild-type M. genitalium G37 except MG408, which was disrupted by an antibiotic marker to block pathogenicity and to allow for selection. To identify the genome as synthetic, we inserted "watermarks" at intergenic sites known to tolerate transposon insertions. Overlapping "cassettes" of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate (...) assemblies of approximately 24 kb, 72 kb ("1/8 genome"), and 144 kb ("1/4 genome"), which were all cloned as bacterial artificial chromosomes in Escherichia coli. Most of these intermediate clones were sequenced, and clones of all four 1/4 genomes with the correct sequence were identified. The complete synthetic genome was assembled by transformation-associated recombination cloning in the yeast Saccharomyces cerevisiae, then isolated and sequenced. A clone with the correct sequence was identified. The methods described here will be generally useful for constructing large DNA molecules from chemically synthesized pieces and also from combinations of natural and synthetic DNA segments. 10.1126/science.1151721.

The recent genome sequencing of a non‐vertebrate deuterostome, the ascidian tunicate Ciona intestinalis, makes a substantial contribution to the fields of evolutionary and developmental biology.1 Tunicates have some of the smallest bilaterian genomes, embryos with relatively few cells, fixed lineages and early determination of cell fates. Initial analyses of the C. intestinalis genome indicate that it has been evolving rapidly. Comparisons with other bilaterians show that C. intestinalis has lost a number of genes, and that many genes linked together in (...) most other bilaterians have become uncoupled. In addition, a number of independent, lineage‐specific gene duplications have been detected. These new results, although interesting in themselves, will take on a deeper significance once the genomes of additional invertebrate deuterostomes (e.g. echinoderms, hemichordates and amphioxus) have been sequenced. With such a broadened database, comparative genomics can begin to ask pointed questions about the relationship between the evolution of genomes and the evolution of body plans.

Abstract:Business negotiations often involve cooperative arrangements. Sometimes one party will renege on a cooperative enterprise for short-term opportunistic gain. There is a common assumption that such behavior necessarily leads to a spiral of mutual antagonism. We use some of the philosophical literature to frame general research questions and identify relevant variables in dealing with defection. We then describe an experimental approach for examining the possibility of reconciliation and discuss the results of one such experiment where participants were the victims (...) of defection. In contrast to the initial assumptions we found that many participants were willing to reconcile, and that penance conditions, when demanded, were less stringent than expected. We suggest that these findings warrant further study and have implications for business dealings.Very little can be learnt about [retribution] from Aristotle’sPoliticsor his three ethics. In modern ethico-political concepts of justice (in Hobbes, Rousseau and Hegel), the problem of retribution appears in conjunction with other problems and is not of central importance.—Agnes Heller.

Mace (bio)Environmental Philosophy and EpistemologyThe purpose of this paper is to help an audience attracted to environmental philosophy get to the core of Gibson's system in a compact form and to appreciate the necessity for an account of the environment in epistemology. I hope to show that Gibson's is a consistent and scientifically progressive account of knowing that (...) gives the environment its due and that this is not a simple matter of fiat but a call to extended scientific investigation. I want to stress that Gibson's work is scientifically progressive in the sense that it has consistently opened new avenues for research. If one could be assured tomorrow that Gibson was correct and his critics wrong, the ecological psychology enterprise would not have to be shut down with nothing left to do. The goal of the enterprise, certainly for Gibson, was not to be declared a winner but to open doors for discovery. Because Gibson has developed a theory of perceiving the environment, it would be worth exploring as an important topic for environmental philosophers covering a wide range of issues. It offers an intriguing, environmentally based, grounding for epistemology; it offers ways to deal [End Page 195] with practical issues within "pure science"; and it is open to reorganizing ways to conceptualize problems beyond epistemology.Gibson developed a richly articulated system that grew steadily over a period of 50 years, 1929 to 1979, which he devoted to "puzzling over" the "perplexities" of vision (1979, xiii). From Gibson's standpoint, knowledge begins with perception, and perception is perceiving the environment. The environment, for Gibson, is at least as essential as the brain to the existence and exercise of "the mind."As an empiricist, knowledge is based on perception for Gibson. But perception, at root, turns out to be perception of the environment. Entities like sense data and representations become "after the fact" curiosities for Gibson, and have no role to play in the foundations of perceptual experience and, a fortiori, knowledge. If Gibson is correct, then scientific accounts of perception must converge on environmental perception. A philosopher whose primary focus is epistemology, and who works within Gibson's system, would perforce be an environmental philosopher—not (first) because of a special concern for the environment, but because an adequate appreciation of relevant facts requires it. Of great importance to environmental philosophers is that Gibson not only provides an account of perceiving grounded in access to environmental properties, but he establishes a basis for perceiving this particular world as a specific arrangement of surfaces. The world we perceive, according to Gibson, is a connected, public world that we share. It is, again, the world, the logical individual world and not an abstraction. This is not an account of the experience of abstract shapes, distances, and motions. It is a system in which travelers can visit the pyramids and in which I can trip over your garbage.Is there a symmetric direction of influence? Just as a commitment to understanding knowledge scientifically and philosophically can lead one to focal considerations of the environment, could a deep concern for the environment as a value lead to the serious study of perception and, more broadly, epistemology? It seems entirely plausible. Gibson's is a "yin and yang" system of scientific complementarities beginning with animal and environment and extending to knowledge and value (in his concept of affordance). In each complementarity, the terms are differentiable but not entirely independent. Animals and their environments are different entities and should not be confused with one another, but they also are so [End Page 196] mutually dependent that one should not imagine a thorough account of one without the other. In like manner, objects and value (first through use) are not independently comprehensible in Gibson's system. This is a theme worthy of careful examination of detailed examples. I am not doing that in this paper, but hope that enough of the flavor of Gibson's work will come through to allow a reader to understand how one might be steered to epistemology from an initial concern with environment and values and...

Should psychology of religion undergo a disciplinary renaissance and, if so, what might it look like? In this paper we explore that question by discussing the benefits of a better grounding of the field within mid-level theories from general psychology that provide it with greater conceptual depth. Such discussion will focus on three already existing and variously productive lines of research as case studies: attribution processes, attachment styles, and religious coping. These case studies represent lines of research at three (...) developmental stages: 1) infancy, with little visible return but with signs of promise , 2) adolescence, with dividends already yielded but also with promise not yet fully realized , and 3) maturity, where a fruitful harvest has already been experienced but yet without decline . Regardless of developmental position, it is argued that research in psychology of religion will be enhanced to the extent that it achieves conceptual depth by being framed in terms of mid-level theories.

Purpose Computing ethics represents a long established, yet rapidly evolving, discipline that grows in complexity and scope on a near-daily basis. Therefore, to help understand some of that scope it is essential to incorporate a range of perspectives, from a range of stakeholders, on current and emerging ethical challenges associated with computer technology. This study aims to achieve this by using, a three-pronged, stakeholder analysis of Computer Science academics, ICT industry professionals, and citizen groups was undertaken to explore what they (...) consider to be crucial computing ethics concerns. The overlap between these stakeholder groups are explored, as well as whether their concerns are reflected in the existing literature. Design/methodology/approach Data collection was performed using focus groups, and the data was analysed using a thematic analysis. The data was also analysed to determine if there were overlaps between the literature and the stakeholders’ concerns and attitudes towards computing ethics. Findings The results of the focus group analysis show a mixture of overlapping concerns between the different groups, as well as some concerns that are unique to each of the specific groups. All groups stressed the importance of data as a key topic in computing ethics. This includes concerns around the accuracy, completeness and representativeness of data sets used to develop computing applications. Academics were concerned with the best ways to teach computing ethics to university students. Industry professionals believed that a lack of diversity in software teams resulted in important questions not being asked during design and development. Citizens discussed at length the negative and unexpected impacts of social media applications. These are all topics that have gained broad coverage in the literature. Social implications In recent years, the impact of ICT on society and the environment at large has grown tremendously. From this fast-paced growth, a myriad of ethical concerns have arisen. The analysis aims to shed light on what a diverse group of stakeholders consider the most important social impacts of technology and whether these concerns are reflected in the literature on computing ethics. The outcomes of this analysis will form the basis for new teaching content that will be developed in future to help illuminate and address these concerns. Originality/value The multi-stakeholder analysis provides individual and differing perspectives on the issues related to the rapidly evolving discipline of computing ethics. (shrink)

“The Will to Believe” defines the religious question as forced, living and momentous, but even in this article James asserts that more objective factors are involved. The competing religious hypotheses must both be equally coherent and correspond to experimental data to an equal degree. Otherwise the option is not a live one. “If I say to you ‘Be a theosophist or be a Mohammedan’, it is probably a dead option, because for you neither hypothesis is likely to be alive.” (...) James, WB, p. 3. Analogously, in A Pluralistic Universe James is at pains to convince the reader that his own religious hypothesis is just as “objective,” makes just as much sense, etc. as alternative possibilities: the “only thing I emphatically insist upon is that it [pluralistic pantheism] is a fully coordinate hypothesis with monism. This world may, in the last resort, be a block universe; but on the other hand, it may be a universe only strung along, not rounded in and closed. Reality may exist distributively just as it sensibly seems to, after all. On that possibility I do insist.”William James, A Pluralistic Universe (New York: Longmans, Green, and Co., 1909) p. 328.Here, once again, before the will to believe can be employed, the objective factors of competing hypotheses, their equal coherence and correspondence, must be brought out.When reconstructed, James' overall outlook has a “qausi Kuhnian” taint to it- though obvious differences remain. Much of what goes on in evaluating competing scientific hypotheses is either not forced, or not living, or not momentous, but rather “typical,” “dead,” and “avoidable,” in short very “normal.” But there are moments in the history of science where the decision between hypotheses might well be forced, living and momentous, and sometimes James comes close to recognizing this.Analogously, a good deal of what goes on in religion is not forced, not living or not momentous - in short it is all too “normal”. In The Varieties of Religious Experience for example, James proposes to ignore the institutional branch of the religious domain and to concentrate on personal and psychological factors, his reason being that the institutional aspect concentrates on the routine, the normal. “Worship and sacrifice, procedures for working on the dispositions of the deity, theology and ceremony and ecclesiastical organization, are the essentials of religion in the institutional branch. Were we to limit our view to it, we should have to define religion as an external art, the art of winning the favor of the gods.” James, VRE, p. 29. and again “The word ‘religion,’ as ordinarily used, is equivocal. A survey of history shows us that, as a rule, religious geniuses attract disciples, and produce groups of sympathizers. When these groups get strong enough to ‘organize’ themselves, they become ecclesiastical institutions with corporate ambitions of their own. The spirit of politics and the lust of dogmatic rule are then apt to enter and to contaminate the originally innocent thing; so that when we hear the word ‘religion’ nowadays, we think inevitably of some ‘church’ or other.” Clearly here religion has a normal, i.e. trivial side, just as does science. On the other hand, there are revolutionary moments in religion, such as that of choosing between theism and materialism in Pragmatism, or choosing among theism, monistic pantheism and pluralistic pantheism in A Pluralistic Universe. Such moments involve the will to believe and are clearly more personal than their counterparts in the domain of normal institutionalized religion. Going further, there are no doubt differences of degree between the will to believe decisions in science and the will to believe decisions in religion. These have been explicated in more specific terms by Ian Barbour in his article, “Paradigms in Science and Religion.” ...each of the ‘subjective’ features of science... is more evident in the case of religion: (1) the influence of interpretation on data, (2) the resistance of comprehensive theories of falsification, and (3) the absence of rules for choice among paradigms. Each of the corresponding ‘objective’ features of science is less evident in the case of religion: (1) the presence of common data on which disputants can agree, (2) the cumulative effect of evidence for or against a theory, and (3) the existence of criteria which are not paradigm-dependent. It is clear that in all three respects religion is a more ‘subjective’ enterprise than science. But in each case there is a difference of degree - not an absolute contrast between an ‘objective’ science and a ‘subjective’ religion. Ian Barbour, “Paradigms in Science and Religion,” in Paradigms and Revolutions, edited by Gary Gutting (Notre Dame: University of Notre Dame Press, 1980) pp. 242–43. Barbour correctly notes that the “...choice is not between religion and science, but between theism, pantheism, and naturalism, let us say, as each is expressed in a particular historical tradition. No basic beliefs are capable of demonstrable proof.”Ibid., p. 243. James sometimes comes close to recognizing this but his oscillation on the status of the everyday world of common sense, or the perceptual world, causes him not to see the issue clearly. When the animated world of the perceptual is taken as the all inclusive ‘really real,’ science is viewed as an abstract, second class citizen. But James offers what we would consider a more sophisticated and adequate perspective when he views the world of common sense, having become linguistified, as itself suspicious, and consequently views all three tiers - common sense, scholastic philosophy, and science - as “regional ontologies”, or “language games” in Wittgenstein's terminologySee Ludwig Wittgenstein, Philosophical Investigations, translated by G.E.M. Anscombe (New York: The Macmillan Company, 1953), paragraph 7, paragraph 23. For the notion of “regional ontology” see Edmund Husserl, Ideas, translated by W.R. Boyce Gibson (New York: Collier Books, Macmillan Publishing Company, Inc., 1962) p. 57ff; p. 158ff. - and opposes all three to a more primordial or prereflexive level. When James takes this second approach it is easier to see that the basic distinction he began to make in “The Will to Believe” was between the scientific and religious domain where the will to believe was to be employed, and the domain of “ordinary” religion and science. Finally this position anticipates his ultimate metaphysical outlook, viz. “pure experience” as approachable through language on a series of diverse regional levels, but nonetheless not completely describable within language. It is important to recall that in The Varieties of Religious Experience James distinguishes between the science of religions and what he calls living religion: [T] he science of religions may not be an equivalent for living religion; and if we turn to the inner difficulties of such a science, we see that a point comes when she must drop the purely theoretic attitude, and either let her knots remain uncut, or have them cut by active faith. James, VRE, p. 489. The study of religion, in short is not the activity of religion; the latter is animated, personal, and, we would argue, necessitates a commitment in terms of the will to believe. Once again, however, James hesitates over offering the same two-fold delineation in other areas of science. On the one hand he tells the reader that “science-has ended by utterly repudiating the personal point of view.”Ibid., p. 491. On the other hand, he offers the following comment a few pages later on in a footnote: ...the divorce between scientist facts and religious facts may not necessarily be as eternal as it at first sight seems, nor the personalism and romanticism of the world, as they appeared to primitive thinking, be matters so irrevocably outgrown. The final opinion may, in short, in some manner now impossible to forsee, revert to the more personal style, just as any path of progress may follow a spiral rather than a straight line. If this were so, the rigorously impersonal view of science might one day appear as having been a temporarily useful eccentricity rather than the definitely triumphant position which the sectarian scientist at present so confidently announces it to be.Ibid., p. 501, Footnote. The burden of this paper has been to indicate that when James' two-fold outlook on perception and/or common sense is properly reconstructed, the raproachment between science and religion is not so “impossible to forsee.”.

nil nisi lasciui per me discuntur amores:femina praecipiam quo sit amanda modo.femina nec flammas nec saeuos discutit arcus;parcius haec uideo tela nocere uiris.It was pointed out in 1992 by E.J. Kenney that femina in line 28 ‘sabotages the poet's … disclaimer’ that it is not women generally but ‘only those not ruled out of bounds by stola and uittae’ who are to benefit from his instruction. He suggests instead that, since what is wanted is a variation on the previous line, (...) one should read nec proba, or, as a better possibility, non proba. Kenney's objection to femina is accepted by Roland Mayer, in a note published the following year. After observing, however, that, ‘when a word has intruded itself from a nearby line and expelled the authentic reading, the ductus litterarum is no guide to emendation’, and that bold measures are therefore admissible, Mayer proposes Thais, comparing Rem. am. 385–6 Thais in arte mea est: lasciuia libera nostra est; | nil mihi cum uitta; Thais in arte mea est. Later, W.S. Watt suggested talis, viz. lasciua, noting talis at 142 and talem at 157. None of these suggestions is entirely compelling, however, and Gibson is therefore right just to obelize femina in his edition; but he also points out in the commentary ad loc. the ‘greater oddity’ relating to amanda, asking ‘Should Ovid not be declaring his intention to teach women how to love, rather than declaring that he will teach how they should be loved?’ and even going so far as to suggest that the whole pentameter is fundamentally corrupt and should be obelized.

Quaternions consist of a scalar plus a vector and result from multiplication or division of vectors by vectors. Division of vectors is equivalent to multiplication divided by a scalar. Quaternions as used here consist of the scalar product with positive sign plus the vector product with sign determined by the right-hand rule. Units are specified by the multiplication process. Trigonometric functions are quaternions with units that can satisfy Hamilton's requirements. The square of a trigonometric quaternion is a real number provided (...) that the product of the scalar number and the vector is not commutative. Maxwell's electromagnetic equations for empty space can be represented by a single quaternion equation. (shrink)

While there are numerous differences between the approaches taken by Maurice Merleau-Ponty and James J. Gibson, the basic motivation of the two thinkers, as well as the internal logic of their respective views, is extraordinarily close. Both were guided throughout their lives by an attempt to overcome the dualism of subject and object, and both devoted considerable attention to their "Gestaltist" predecessors. There can be no doubt but that it is largely because of this common cause that the subsequent (...) development of their ideas is so similar. It is not my objective in what follows merely to demonstrate a similarity between two lines of thought. Instead, I will try to show that each approach gains considerably from attention to the other. There are numerous ways to begin such a project, each about as arbitrary as the next. For present purposes, I shall take as of central importance the question of the character of the perceived world, both in relation to the traditionally opposed mental and material "substances", and in relation to its identification and individuation of things vis a vis one another and vis a vis ourselves. This will implicate especially Gibson's "affordances" and Merleau-Ponty's thesis concerning the "materiality of meaning.". (shrink)

With displacement, time, and force as basic undefined physical quantities, other physical quantities are defined as combinations of two vector quantities and one scalar quantity. Combinations include multiplication and division of vectors by vectors, scalars by vectors, and scalars by scalars. Defined quantities are vectors, scalars or quaternions, depending on directions of vectors in the definitions. Division of a vector by a vector is equivalent to multiplication of vectors divided by a scalar. The unit of a vector (or scalar) is (...) itself a vector (or scalar) quantity. Thesquare meter (a vector) differs from meter 2 (a scalar), and the cubic meter (a scalar) is different frommeter 3 . The characteristics of displacement, time, and force are considered known from experience. (shrink)

The perceptual psychologist J. J. Gibson embraces a radically externalistic view of mind and action. We have, for Gibson, not a Cartesian mind or soul, with its interior theater of contents and the consequent problem of explaining how this mind or soul and its psychological environment can succeed in grasping physical objects external to itself. Rather, we have a perceiving, acting organism, whose perceptions and actions are always already tuned to the parts and moments, the things and surfaces, (...) of its external environment. We describe how on this basis Gibson sought to develop a realist science of environments which will be ‘consistent with physics, mechanics, optics, acoustics, and chemistry’. (shrink)

Background Regionalised models of health care delivery have important implications for people with disabilities and chronic illnesses yet the ethical issues surrounding disability and regionalisation have not yet been explored. Although there is ethics-related research into disability and chronic illness, studies of regionalisation experiences, and research directed at improving health systems for these patient populations, to our knowledge these streams of research have not been brought together. Using the Canadian province of Ontario as a case study, we address this gap (...) by examining the ethics of regionalisation and the implications for people with disabilities and chronic illnesses. The critical success factors we provide have broad applicability for guiding and/or evaluating new and existing regionalised health care strategies. Discussion Ontario is in the process of implementing fourteen Local Health Integration Networks (LHINs). The implementation of the LHINs provides a rare opportunity to address systematically the unmet diverse care needs of people with disabilities and chronic illnesses. The core of this paper provides a series of composite case vignettes illustrating integration opportunities relevant to these populations, namely: (i) rehabilitation and services for people with disabilities; (ii) chronic illness and cancer care; (iii) senior's health; (iv) community support services; (v) children's health; (vi) health promotion; and (vii) mental health and addiction services. For each vignette, we interpret the governing principles developed by the LHINs – equitable access based on patient need, preserving patient choice, responsiveness to local population health needs, shared accountability and patient-centred care – and describe how they apply. We then offer critical success factors to guide the LHINs in upholding these principles in response to the needs of people with disabilities and chronic illnesses. Summary This paper aims to bridge an important gap in the literature by examining the ethics of a new regionalisation strategy with a focus on the implications for people with disabilities and chronic illnesses across multiple sites of care. While Ontario is used as a case study to contextualize our discussion, the issues we identify, the ethical principles we apply, and the critical success factors we provide have broader applicability for guiding and evaluating the development of – or revisions to – a regionalised health care strategy.

The paper introduces the concepts at the heart of point-set-topology and of mereotopology (topology founded in the non-atomistic theory of parts and wholes) in an informal and intuitive fashion. It will then seek to demonstrate how mereotopological ideas can be of particular utility in cognitive science applications. The prehistory of such applications (in the work of Husserl, the Gestaltists, of Kurt Lewin and of J. J. Gibson) will be sketched, together with an indication of the field of (...) possibilities in linguistics, perceptual psychology, cate¬gorization and geographic information systems. Topological structures will be shown to play a central role in studies of naive physics not least in virtue of the fact that even well-attested departures from true physics on the part of common sense leave the topology and vectorial orientation of the underlying physical phenomena invariant: our common sense would thus seem to have a veridical grasp of the topology and broad general orientation of physical phenomena, both static and dynamic, even where it illegitimately modifies the relevant shape and metric properties. The implications of this and related insights for the methodology of psychology will be explored. (shrink)

Psychological and philosophical studies have extended J. J. Gibson’s notion of affordances. Affordances are possibilities for bodily action presented to us by the objects of our perception. Recent work has argued that we should extend the actions afforded by perception to mental action. I argue that we can extend the notion of affordance itself. What I call ‘Introspective Affordances’ are possibilities for mental action presented to us by introspectively accessible states. While there are some prima facie worries concerning the (...) non-perceptual nature of introspection, I will argue that our internal mental lives share enough commonalities with experiences in our environment to warrant this extension. I will demonstrate the value of introspective affordances by showing how they allow us to explain an underexplored aspect of thought insertion. (shrink)

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another.

These essays are meant for personal reflection and above all, for thoughtful discussion with mentors, with peers, with others throughout the health care provider community who care about acting professionally.

BackgroundArtificial intelligence has been described as the “fourth industrial revolution” with transformative and global implications, including in healthcare, public health, and global health. AI approaches hold promise for improving health systems worldwide, as well as individual and population health outcomes. While AI may have potential for advancing health equity within and between countries, we must consider the ethical implications of its deployment in order to mitigate its potential harms, particularly for the most vulnerable. This scoping review addresses the following question: (...) What ethical issues have been identified in relation to AI in the field of health, including from a global health perspective?MethodsEight electronic databases were searched for peer reviewed and grey literature published before April 2018 using the concepts of health, ethics, and AI, and their related terms. Records were independently screened by two reviewers and were included if they reported on AI in relation to health and ethics and were written in the English language. Data was charted on a piloted data charting form, and a descriptive and thematic analysis was performed.ResultsUpon reviewing 12,722 articles, 103 met the predetermined inclusion criteria. The literature was primarily focused on the ethics of AI in health care, particularly on carer robots, diagnostics, and precision medicine, but was largely silent on ethics of AI in public and population health. The literature highlighted a number of common ethical concerns related to privacy, trust, accountability and responsibility, and bias. Largely missing from the literature was the ethics of AI in global health, particularly in the context of low- and middle-income countries.ConclusionsThe ethical issues surrounding AI in the field of health are both vast and complex. While AI holds the potential to improve health and health systems, our analysis suggests that its introduction should be approached with cautious optimism. The dearth of literature on the ethics of AI within LMICs, as well as in public health, also points to a critical need for further research into the ethical implications of AI within both global and public health, to ensure that its development and implementation is ethical for everyone, everywhere.

Values exist not in isolation, but in complex wholes. Values are what they are because of the complex wholes in which they are situated. To do justice to this thesis will require a holistic ontology, a theory according to which many types of entities exist only as inseparable parts or moments of wider contexts or environments. An ontological theory of environments -- with roots in Gestalt psychology and the ecological psychology of J. J. Gibson and Roger Barker, and (...) which is related also to the theory of motivation sketched by Edmund Husserl as part of his theory of the lifeworld or Lebenswelt -- will help us to understand the ontology of values. It will help us to understand what values are. It will not, however, tell us what is good or bad. From facts of ontology, no value propositions follow. (shrink)

BackgroundThe amount of research utilizing health information has increased dramatically over the last ten years. Many institutions have extensive biobank holdings collected over a number of years for clinical and teaching purposes, but are uncertain as to the proper circumstances in which to permit research uses of these samples. Research Ethics Boards (REBs) in Canada and elsewhere in the world are grappling with these issues, but lack clear guidance regarding their role in the creation of and access to registries and (...) biobanks.MethodsChairs of 34 REBS and/or REB Administrators affiliated with Faculties of Medicine in Canadian universities were interviewed. Interviews consisted of structured questions dealing with diabetes-related scenarios, with open-ended responses and probing for rationales. The two scenarios involved the development of a diabetes registry using clinical encounter data across several physicians' practices, and the addition of biological samples to the registry to create a biobank.ResultsThere was a wide range of responses given for the questions raised in the scenarios, indicating a lack of clarity about the role of REBs in registries and biobanks. With respect to the creation of a registry, a minority of sites felt that consent was not required for the information to be entered into the registry. Whether patient consent was required for information to be entered into the registry and the duration for which the consent would be operative differed across sites. With respect to the creation of a biobank linked to the registry, a majority of sites viewed biobank information as qualitatively different from other types of personal health information. All respondents agreed that patient consent was needed for blood samples to be placed in the biobank but the duration of consent again varied.ConclusionParticipants were more attuned to issues surrounding biobanks as compared to registries and demonstrated a higher level of concern regarding biobanks. As registries and biobanks expand, there is a need for critical analysis of suitable roles for REBs and subsequent guidance on these topics. The authors conclude by recommending REB participation in the creation of registries and biobanks and the eventual drafting of comprehensive legislation. (shrink)

I argue that the most promising approach to understanding J.J. Gibson's "affordances" takes affordances themselves as ontological primitives, instead of treating them as dispositional properties of more primitive things, events, surfaces, or substances. These latter are best treated as coalescences of affordances present in the environment (or "coalescences of use-potential," as in Sanders (1994) and Hilditch (1995)). On this view, even the ecological approach's stress on the complementary organism/environment pair is seen as expressing a particular affordance relation between the (...) world and the analyst. That the world is parsed in any way among events and objects, perceivers and worlds, etc., reflects equally features of certain real or possible perspectives on the world and features of the world itself. In section 1, I begin by contending that, contrary to the apparent expectations of some in the field, the bare existence of affordances is surely quite uncontroversial. In section 2, I argue that the most reasonable approach to foundational ontology is a relativistic one. In section 3, I address the claim that affordances must be ontologically complemented by effectivities for the sake of completeness, and I shall argue against that claim on grounds that I take to reflect some of Gibson's most important insights. This work will help to clarify the way affordances are to be used in the fourth and final section, where I argue that ontological work, even within special sciences, should not be merely "regional," and that the most attractive general approach to ontological questions is one that is based on affordances, rather than upon things, events, surfaces, and the like.

James J. Gibson is one of the best known and perhaps most controversial visual theorists of the twentieth century. Writing in the vein of the American functionalists, and immersed in their profound sense of pragmatism, Gibson sought to establish a more rigorous foundation for the study of vision by reworking its most fundamental concepts. Over the five decades of his distinguished career, Gibson brought new clarity to the old problems of the tradition. He offered an alternative theory (...) of perception - one that could accommodate the experimental insights of contemporary research programs. He characterized this new theory as a version of direct perception in order to distinguish it from the traditional indirect approach of Rene Descartes. On Descartes' account, our perceptual awareness of reality comes through the representations we have formed of it within ourselves. In contrast, Gibson's theory of direct perception states that the environment contains all of the information needed to specify its properties. Hence, perceiving these properties is a matter of detecting the information available in the environment. This theory avoids the difficulty of explaining how the mind organizes holistic perceptions from atomic sensations. In what follows, I will attempt to make good these claims by situating the concept of "structure" at the heart of the ecological program. I will argue that this concept is significant precisely because it allows Gibson to locate the moving, perceiving body at the heart of meaningful perceptual experience; an experience which emerges in the dynamical structures that cross the body and the world.
