The introduction of Artificial Intelligence systems has demonstrated impeccable potential and benefits to enhance the decision-making processes in our society. However, despite the successful performance of AI systems to date, skepticism and concern remain regarding whether AI systems could form a trusting relationship with human users. Developing trusted AI systems requires careful consideration and evaluation of its reproducibility, interpretability, and fairness, which in in turn, poses increased expectations and responsibilities for data scientists. Therefore, the current study focused on understanding Canadian (...) data scientists’ self-confidence in creating trusted AI systems, while relying on their current AI system development practices.

Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, OI is not a (...) sufficient independence condition for warranting robustness arguments. We show that OI evidence can collectively confirm a hypothesis to a lower degree than individual lines of evidence, contrary to the standard assumption undergirding usual robustness arguments. We employ Bayesian networks to represent the ideal empirical scenario for a robustness argument and a variety of ways in which empirical scenarios can fall short of this ideal. (shrink)

Phase transitions are an important instance of putatively emergent behavior. Unlike many things claimed emergent by philosophers (e.g., tables and chairs), the alleged emergence of phase transitions stems from both philosophical and scientific arguments. Here we focus on the case for emergence built from physics, in particular, arguments based upon the infinite idealization invoked in the statistical mechanical treatment of phase transitions. After teasing apart several challenges, we defend the idea that phase transitions are best thought of as conceptually novel, (...) but not ontologically or explanatorily irreducible to finite physics; indeed, by looking at ongoing work on “smooth phase transitions” we even suggest that they’re not even conceptually novel. In the case of renormalization group theory, consideration of infinite systems and their singular behavior provides a central theoretical tool, but this is compatible with an explanatory reduction. Phase transitions may be “emergent” in some sense of this protean term, but not in a sense that is incompatible with the reductionist project broadly construed. (shrink)

The value-free ideal for science holds that values should not influence the core features of scientific reasoning. We defend the difference-to-inference model of value-permeation, which holds that value-permeation in science is problematic when values make a difference to the inferences made about a hypothesis. This view of value-permeation is superior to existing views, and it suggests a corresponding maxim—namely, that scientists should strive to eliminate differences to inference. This maxim is the basis of a novel value-free ideal for science. -/- (...) . (shrink)

Objective To document the legal guardian-related barriers to consent procurement, and their stated reasons for non-participation in a paediatric critical care research study.Study design A multicentre, prospective, cohort study.Participants Legal guardians of children who participated in a multicentre study on adrenal insufficiency in paediatric critical illness. Data were collected on all consent encounters in the main study.Methods Screening data, reasons for consent not being obtained, paediatric risk of mortality scores and age were collected on all 1707 patients eligible for participation (...) in the Adrenal Insufficiency Study.Results The main barriers to approaching legal guardians for consent were lack of availability of the legal guardians and language barriers . Legal guardians of 917 patients were approached with an overall consent rate of 42% . 81% of the 528 legal guardians who declined consent provided an unsolicited reason for refusal. The three most commonly stated reasons were: being overwhelmed , not wanting anything else done to their child and not wanting an additional medication . In addition, 14.2% cited research-related concerns as the reason for their non-participation.Conclusions Barriers to consent procurement in a non-therapeutic paediatric critical care study appear to occur at many levels with lack of availability of legal guardians, and legal guardians feeling overwhelmed, being the most commonly recorded reasons. Further research into the impact of these findings on the validity and generalisability of the results of such studies is necessary prior to the development and study of future consent models.

In lieu of an abstract, here is a brief excerpt of the content:Legal CommentarySumy Menon, Senior Associate in ResearchThis case involves the balancing of a young person’s right to autonomy and the desire to protect her from harm. No Singapore court decision has determined whether the doctor owes a duty to the parents of the doctor’s 16-year-old patient, to warn them that their child is engaging in sexual activities, and who subsequently has had an abortion. Similarly, the issue of (...) whether the doctor has a duty to protect the minor in such circumstances has also not been tested in the Singapore courts. Nonetheless, it is very unlikely that either duty will be found in this case.The general rule is that doctors owe a duty of confidentiality to their patients. This duty extends to children, and although no Singapore court has ruled on the matter, the law in England is clear.1 It is enshrined in section 4.2.3.1 of the Ethical Code & Ethical Guidelines of the Singapore Medical Council. It is not absolute and a number of exceptions have been carved out. The confidentiality duty can be overridden by legislation, court order, the public interest, or other justifiable circumstances that the doctor believes warrants disclosure.The age of consent for non-commercial consensual sexual activities in Singapore is 16.2 Therefore, there is no statutory responsibility on Dr. C under the criminal law to report the patients’ sexual activities to the authorities or anyone else. There is no other legislation or court order that compels disclosure. It is highly unlikely that the public interest would be served by disclosure. The consequences of such disclosure to the public interest were aptly put in a recent English case, when J. Silber held that if a confidentiality duty was not imposed, it “would probably or might well deter young people [End Page 262] from seeking advice and treatment on contraception, sexually transmitted diseases and abortion, and this would have undesirable and troubled consequences”.3 The last exception offers the greatest latitude for doctors to disclose if they believe there are other justifiable circumstances that would shift the balance in favour of disclosure. There are strong reasons to maintain confidentiality in Miss M’s case and although an argument can be made for disclosure, that argument is relatively weak.Miss M’s parents are understandably worried about her but Dr. C should not breach the duty of confidentiality owed to the patient even though she is only 16 years old. It is irrelevant that Miss M’s parents are paying for their daughter’s treatment. The doctor-patient relationship is between Dr. C and Miss M, and her parents have never been involved in the consultations or treatment decision-making process. They have not insisted on attending the consultations with their daughter, nor did they appear to object to Miss M consenting to treatment. Prior to their complaint, they had not sought any update or information about their daughter’s condition from Dr. C. Miss M specifically asked Dr. C not to reveal the contents of their conversations to her parents at the first consultation and the doctor agreed after attempting to convince her that it would be preferable to include her parents in the consultations. Miss M was obviously concerned about confidentiality and sought clarification from Dr. C. It appears as though Dr. C determined that Miss M had the capacity to exclude her parents from the consultations, and later to make her own treatment decisions, as a mature minor, and their doctor-patient relationship proceeded on that basis.It may be in the public interest for Dr. C to disclose confidential information about Miss M, even if she refuses to consent to it, if the doctor believes it is necessary to protect her from serious harm. Any such decision must be made with the patient’s best interests in mind. Examples of such harm include situations where the patient is at risk of serious physical abuse or has voiced a desire to commit suicide. Engaging in sexual activity with an older boy is unlikely to result in such serious harm, although harm may result. In this case, that harm manifested itself in an unwanted pregnancy... (shrink)

Abstract The word ‘meme’ was first used by Richard Dawkins (Dawkins, 1976)1 in the sense of a replicator to introduce the idea of cultural transmission through the process of imitation, just as genes are responsible for the evolution of organisms. Following Dawkins several writers came forth to have a closer look at ‘meme’. The consensus was that this was a fascinating way of explaining cultural evolution and transmission; that meme is the basic unit of (cultural) information whose existence influences events (...) so as to make more copies of itself (Brodie, 1996).2 The book which got most attention in this line of literature wasThe Meme Machine (Blackmore, 1993),3 which favours the idea that culture, like biology, evolves through the process of variation, selection and replication. Something striking in Blackmore’s thesis is that emotions and attitudes do not count as memes since they are subjective and never get passed on. http://link.springer.com/article/10.1007%2FBF02780405?LI=true.

The value-free ideal in science has been criticised as both unattainable and undesirable. We argue that it can be defended as a practical principle guiding scientific research even if the unattainability and undesirability of a value-free end-state are granted. If a goal is unattainable, then one can separate the desirability of accomplishing the goal from the desirability of pursuing it. We articulate a novel value-free ideal, which holds that scientists should act as if science should be value-free, and we argue (...) that even if a purely value-free science is undesirable, this value-free ideal is desirable to pursue.

For Knox, ‘spacetime’ is to be defined functionally, as that which picks out a structure of local inertial frames. Assuming that Knox is motivated to construct this functional definition of spacetime on the grounds that it appears to identify that structure which plays theoperationalrole of spacetime—i.e., that structure which is actually surveyed by physical rods and clocks built from matter fields—we identify in this paper important limitations of her approach: these limitations are based upon the fact that there is a (...) gap between inertial frame structure and that which is operationally significant in the above sense. We present five concrete cases in which these two notions come apart, before considering various ways in which Knox’s spacetime functionalism might be amended in light of these issues. (shrink)

Brown and Pooley’s ‘dynamical approach’ to physical theories asserts, in opposition to the orthodox position on physical geometry, that facts about physical geometry are grounded in, or explained by, facts about dynamical fields, not the other way round. John Norton has claimed that the proponent of the dynamical approach is illicitly committed to spatiotemporal presumptions in ‘constructing’ space-time from facts about dynamical symmetries. In this article, I present an abstract, algebraic formulation of field theories and demonstrate that the proponent of (...) the dynamical approach is not committed, in special relativity, to the illicit presumptions to which Norton refers.

Recent work in the physics literature demonstrates that, in particular classes of rotating spacetimes, physical light rays in general do not traverse null geodesics. Having presented this result, we discuss its philosophical significance, both for the clock hypothesis, and for the operational meaning of the metric field.

If we cannot directly empirically test the claims of particular scientific theory, then it would be nice to have some other criteria with which to assess its viability. In his 2013 book, String Theory and the Scientific Method, Richard Dawid aims to develop such criteria, with an eye to vindicating research programs in disciplines where direct empirical data is scant or non-existent. In an accompanying paper, Dawid, Hartmann and Sprenger formalise Dawid’s so-called ‘No Alternatives Argument’ using a generalised Bayesian framework, (...) as a first step towards formalising Dawid’s entire re- search programme. In this paper, I argue that the formalisation of the NAA cannot play the central role in Dawid’s programme as intended. This is based on the observation that not all confirmation is non-negligible confirmation. For Dawid’s programme to be useful, it must demonstrate the viability not just of non-empirical theory confirmation, but of non-negligible non-empirical theory confirmation. I argue that Dawid et al.’s appeal to Bayesian confirmation theory to formalise his NAA cannot guarantee non-negligible confirmation. As a result, I conclude that if Dawid’s overall project is to succeed, it must do so without the NAA formalised in this way. (shrink)

Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the scale—and ultimately the concept of a point—makes sense in such a theory. We argue that it does not, in two interrelated ways. In the context of Connes’ spectral triple approach, we show that arbitrarily small regions are not definable in the formal sense. While in the scalar (...) field Moyal–Weyl approach, we show that they cannot be given an operational definition. We conclude that points do not exist in such geometries. We therefore investigate (a) the metaphysics of such a geometry, and (b) how the appearance of smooth manifold might be recovered as an approximation to a fundamental noncommutative geometry.

Supersymmetry (SUSY) is a proposed symmetry between bosons and fermions. The structure of the space of SUSY generators is such that the distinction between internal and spacetime symmetries is blurred. As a result, there are two viable candidates for the correct spacetime setting for a flat supersymmetric field theory---Minkowski spacetime and superspace. an extension of four- dimensional Minkowski spacetime to include (at least) four new dimensions, coordinatised by mathematical objects known as supernumbers. These objects are, in one significant way, quite (...) different from real or complex number---some of them have the property that their order of multiplication makes a difference; in mathematical terms, they are said to have nontrivial commutation properties. This paper argues for two theses: first, that one standard set of arguments, related to universality of symmetry behaviour, that motivate a particular choice of spacetime structure in familiar spacetime theories motivates the choice of superspace as the appropriate spacetime for SUSY field theories. And second, that the metaphysical utility of the concept of spacetime requires more than just the satisfaction of this universality condition; in supersymmetric theories, the spacetime concept is not as useful as in special relativity.

Family involvement in healthcare decision-making for competent patients occurs to varying degrees in many communities around the world. There are different attitudes about who should make treatment decisions, how and why. Legal and professional ethics codes in most jurisdictions reflect and support the idea that competent patients should be enabled to make their own treatment decisions, even if others, including their healthcare professionals, disagree with them. This way of thinking contrasts with some cultural norms that put more emphasis on the (...) family as a decision-making entity, in some circumstances to the exclusion of a competent patient. Possible tensions may arise between various combinations of patient, family members and healthcare professionals, and healthcare professionals must tread a careful path in navigating family involvement in the decision-making process. These tensions may be about differences of opinion about which treatment option is best and/or on who should have a say or influence in the decision-making process. While some relevant cultural, legal and policy considerations vary from community to community, there are ethical issues that healthcare professionals need to grapple with in balancing the laws and professional codes on decision-making and the ethical principle of respecting patients and their autonomy. This paper will highlight and propose that a partial resolution to these issues may lie in relational understandings of autonomy, which in principle justify interventions by healthcare professionals and family that support patients in decision-making.

Therapeutic privilege is a defence that may be available to doctors who fail to disclose to the patient relevant information when seeking informed consent for treatment if they have a reasonable belief that providing that information would likely cause the patient concerned serious physical or mental harm. In a landmark judgement, the Singapore Court of Appeal introduced a novel interpretation of TP, identifying circumstances in which it might be used with patients who did not strictly lack capacity but might be (...) inclined to refuse recommended treatments. In this paper, we explore the conceptual and practical challenges of this novel interpretation of TP. We propose that more emphasis should be placed on forms of shared and supported decision-making that foster the autonomy of patients with compromised mental capacity while being mindful of the need to safeguard their well-being. The kind of privilege that doctors might need to invoke is one of time and supportive expertise to ensure a flexible, responsive approach calibrated to the individual patients’ needs. The provision of such service would extinguish the need for the novel TP proposed by the Singapore Court of Appeal. (shrink)
