Information protocols (IP's) were developed to describe players who learn their social situation by their experiences. Although IP's look similar to colored multi-graphs (MG's), the two objects are constructed in fundamentally different ways. IP's are constructed using the global concept of history, whereas graphs are constructed using the local concept of edges. We give necessary and sufficient conditions for each theory to be captured by the other. We find that the necessary and sufficient condition for IP theory to be captured (...) by MG theory, which we call SE, excludes relevant game situations. Hence, we conclude that IP theory remains a vital tool and cannot be replaced by MG theory. (shrink)

We argue that the intractable part of the measurement problem -- the 'big' measurement problem -- is a pseudo-problem that depends for its legitimacy on the acceptance of two dogmas. The first dogma is John Bell's assertion that measurement should never be introduced as a primitive process in a fundamental mechanical theory like classical or quantum mechanics, but should always be open to a complete analysis, in principle, of how the individual outcomes come about dynamically. The second dogma is the (...) view that the quantum state has an ontological significance analogous to the significance of the classical state as the 'truthmaker' for propositions about the occurrence and non-occurrence of events, i.e., that the quantum state is a representation of physical reality. We show how both dogmas can be rejected in a realist information-theoretic interpretation of quantum mechanics as an alternative to the Everett interpretation. The Everettian, too, regards the 'big' measurement problem as a pseudo-problem, because the Everettian rejects the assumption that measurements have definite outcomes, in the sense that one particular outcome, as opposed to other possible outcomes, actually occurs in a quantum measurement process. By contrast with the Everettians, we accept that measurements have definite outcomes. By contrast with the Bohmians and the GRW 'collapse' theorists who add structure to the theory and propose dynamical solutions to the 'big' measurement problem, we take the problem to arise from the failure to see the significance of Hilbert space as a new kinematic framework for the physics of an indeterministic universe, in the sense that Hilbert space imposes kinematic objective probabilistic constraints on correlations between events.

Ryan Tonkens has issued a seemingly impossible challenge, to articulate a comprehensive ethical framework within which artificial moral agents satisfy a Kantian inspired recipe—"rational" and "free"—while also satisfying perceived prerogatives of machine ethicists to facilitate the creation of AMAs that are perfectly and not merely reliably ethical. This series of papers meets this challenge by landscaping traditional moral theory in resolution of a comprehensive account of moral agency. The first paper established the challenge and set out autonomy in Aristotelian terms. (...) The present paper interprets Kantian moral theory on the basis of the preceding introduction, argues contra Tonkens that an engineer does not violate the categorical imperative in creating Kantian AMAs, and proposes that a Kantian AMA is not only a possible goal for Machine ethics research, but a necessary one.

Online retailers are using advances in data collection and computing technologies to “personalize” prices, i.e., offer goods for sale to shoppers at their reservation prices, or the highest price they are willing to pay. In this paper, I offer a criticism of this practice. I begin by putting online personalized pricing in context. It is not something entirely new, but rather a kind of price discrimination, a familiar pricing practice. I then offer a fairness-based argument against it. When an online (...) retailer personalizes prices, it competes unfairly for the social surplus created by a transaction. I defend this argument against objections, and offer a simple remedy: online retailers should either disclose that they are personalizing prices, or stop doing so. (shrink)

We present here a hierarchical model for the evolution of compositional language. The model has the structure of a two-sender/one-receiver Lewis signaling game augmented with executive agents who m...

A simple tool is provided to assist researchers in assessing contributions to a scientific publication, for ease in evaluating which contributors qualify for authorship, and in what order the authors should be listed. The tool identifies four phases of activity leading to a publication—Conception and Design, Data Acquisition, Analysis and Interpretation, and Manuscript Preparation. By comparing a project participant’s contribution in a given phase to several specified thresholds, a score of up to five points can be assigned; the contributor’s scores (...) in all four phases are summed to yield a total “contribution score”, which is compared to a threshold to determine which contributors merit authorship. This tool may be useful in a variety of contexts in which a systematic approach to authorial credit is desired. (shrink)

Lewis signaling games illustrate how language might evolve from random behavior. The probability of evolving an optimal signaling language is, in part, a function of what learning strategy the agents use. Here we investigate three learning strategies, each of which allows agents to forget old experience. In each case, we find that forgetting increases the probability of evolving an optimal language. It does this by making it less likely that past partial success will continue to reinforce suboptimal practice. The learning (...) strategies considered here show how forgetting past experience can promote learning in the context of games with suboptimal equilibria. (shrink)

The contentious, topical debate about whether faith-based health care organizations should be granted accommodation on the basis of institutional conscientious objection to medical assistance is dying (MAiD) is addressed through a comparative analysis of arguments on both sides of the issue that references such relevant considerations as: claimed ‘moral-authority’, competing rights-based claims, obligations arising from patient welfare principles, formal justice, dissimilarity in consequences, and two illustrative arguments from analogy. The analysis leads to the conclusion that nonconditional accommodation on the basis (...) of institutional conscientious objection to MAiD is not ethically acceptable in Canada. A compromise mechanism, consisting of a suggested set of pragmatic conditions, is proposed that could effectively balance the competing moral responsibilities that arise from this conclusion and a core assumption of the paper, i.e., that some dominant faith-based health institutions can legitimately request, and expect, that provincial/territorial governments pay them a measure of respect in their operational, health-care-delivery decision making because of these institutions’ long history of providing high quality, health care in Canada. It is further suggested that provincial/territorial governments only allow large, publicly funded, faith-based health care organizations to enact a conditional version of accommodation on the basis of institutional conscientious objection to MAiD in circumstances where the organization has entered into a formal agreement with the relevant health department to meet the proposed, compromise conditions (or a relevantly-similar set of conditions).

As social theorists seek to understand the contemporary challenges of radical populism, we would do well to reconsider the febrile insights of the psychoanalytic social theorist Erich Fromm. It was Fromm who, at the beginning of the 1930s, conceptualized the emotional and sociological roots of a new ‘authoritarian character’ who was meek in the face of great power above and ruthless to the powerless below. It was Fromm, in the 1950s, who argued that societies, not only individuals, could be sick. (...) This essay traces the intertwining of psychoanalytic and sociological methods that allowed Fromm to create such new ideas. At the same time, it highlights how Fromm’s sociology was hampered by an economistic Marxist approach to the institutions and culture of democratic capitalist societies. Such theoretical restriction prevented Fromm from conceptualizing how institutions like democracy, science, and psychotherapy can provide resources for widespread emotional recuperation and civil repair.

In this case study, I address the procedural ethics of conversation analysis (CA) and the collection of naturally occurring mundane interactions. I draw from the challenges that emerged from the institutional ethics review of the HIV, health and interaction study (the H2I Study), a CA project that sought to identify the practices through which normative assumptions of HIV and other health conditions are produced in conversations. Consistent with CA’s preference for naturally occurring interactions, the H2I Study collected and analysed everyday (...) telephone calls involving people living with HIV. This article offers practical strategies CA researchers might use to navigate two ethical concerns raised about the collection of naturally occurring mundane interactions. The first questions the merits of collecting naturally occurring mundane interactions. For those unfamiliar with CA, the specific advantages of analysing naturally occurring mundane interactions may not be self-evident. This places an evidentiary burden on CA researchers to warrant the collection of this type of data. To address this concern, I suggest demonstrating in ethics applications the analytic value of CA using publicly available interactions. The second concern questions the use of verbal consent necessary for the collection of naturally occurring mundane interactions. Like most CA research, the H2I Study required flexible informed consent protocols appropriate for spontaneous and unpredictable interactions. Drawing from within and outside the CA literature, I offer three rationales for the use of verbal consent. This article is written as a practical resource for conversation analysts seeking approval from their research ethics board (REB) and for REBs who might be unfamiliar with CA research. This article contributes to a small but growing body of literature that documents not only the kinds of challenges CA researchers encounter from institutional ethics review, but the specific procedural ethics they may employ to secure ethics approval.

Incapacitated adult patients are commonly divided into two groups for purposes of decision making; those with a surrogate and those without. Respectively, these groups are often referred to as represented and unrepresented, and the relative ethics of decision making between them raises two particular issues. The first issue involves the differential application of the best interests standard between groups. Second is the prevailing notion that representedness and unrepresentedness are categorical phenomena, though it is more aptly understood as a multidimensional and (...) continuous variable based on relational moral authority. This paper examines the nature of representedness as it relates to ethical norms of surrogate decision making. (shrink)

Nearly 30 years ago, Terry Horgan and Mark Timmons published a now- popular article that combines Hilary Putnam’s Twin Earth scenario with G.E. Moore’s open question argument in an effort to show that moral naturalism – the view that moral facts are at bottom ordinary, natural facts of some sort – is probably false. Responses to Horgan and Timmons’s “revised open question argument” have been legion, but surprisingly, no one has attempted to test the core assumption upon which the argument (...) is based; namely, that competent language users univocally treat natural kind-terms as rigid designators. Here, I present evidence that the intuitions of competent English speakers are not as univocal as Horgan and Timmons need them to be to ground their argument against moral naturalism. I also briefly sketch a way that the moral naturalist can respond even if competent language speakers do treat natural-kind terms in the way that Horgan and Timmons suggest. (shrink)

We prove a uniqueness theorem showing that, subject to certain natural constraints, all 'no collapse' interpretations of quantum mechanics can be uniquely characterized and reduced to the choice of a particular preferred observable as determine (definite, sharp). We show how certain versions of the modal interpretation, Bohm's 'causal' interpretation, Bohr's complementarity interpretation, and the orthodox (Dirac-von Neumann) interpretation without the projection postulate can be recovered from the theorem. Bohr's complementarity and Einstein's realism appear as two quite different proposals for selecting (...) the preferred determinate observable--either settled pragmatically by what we choose to observe, or fixed once and for all, as the Einsteinian realist would require, in which case the preferred observable is a 'beable' in Bell's sense, as in Bohm's interpretation (where the preferred observable is position in configuration space).

Skyrms-Lewis signaling games illustrate how meaningful language may evolve from initially meaningless random signals (Lewis, Convention 1969; Skyrms 2008). Here we will consider how incommensurable languages might evolve in the context of signaling games. We will also consider the types of incommensurability exhibited between evolved languages in such games. We will find that sequentially evolved languages may be strongly incommensurable while still allowing for increasingly faithful descriptions of the world.

Is the restricted, consistent, version of the T-scheme sufficient for an ‘implicit definition’ of truth? In a sense, the answer is yes (Haack 1978 , Quine 1953 ). Section 4 of Ketland 1999 mentions this but gives a result saying that the T-scheme does not implicitly define truth in the stronger sense relevant for Beth’s Definability Theorem. This insinuates that the T-scheme fares worse than the compositional truth theory as an implicit definition. However, the insinuation is mistaken. For, as Bays (...) rightly points out, the result given extends to the compositional truth theory also. So, as regards implicit definability, both kinds of truth theory are equivalent. Some further discussion of this topic is mentioned (Gupta 2008 , Ketland 2003 , McGee 1991 ), all in agreement with Bays’s analysis. (shrink)

We consider the efficacy of various forms of reinforcement learning with punishment in evolving linguistic conventions in the context of Lewis-Skyrms signalling games. We show that the learning strategy of reinforcement with iterative punishment is highly effective at evolving optimal conventions in even complex signalling games. It is also robust and can be easily extended to a self-tuning variety of reinforcement learning. We briefly discuss some of the virtues of reinforcement with iterative punishment and how it may be related to (...) learning in nature. (shrink)

The modern practice of organ donation after cardiocirculatory death (DCD) emerged in the 1990s as a response to the alarmingly wide gap between the number of transplantable organs available through organ donation after neurological death and the urgent organ transplantation needs of persons in end-organ failure. Various important ethical dimensions of DCD have been considered and debated by prominent organ donation/transplantation theorists and clinicians.In this article, consideration of some of these ethical elements provides a foundation for a proposed set of (...) ethically informed, pragmatic conditions that could assist in the development of health policies to guide the practice of organ donation after cardiocirculatory death.
