In prior papers the following question was considered: which classes of computable sets can be learned if queries about those sets can be asked by the learner? The answer depended on the query language chosen. In this paper we develop a framework for studying this question. Essentially, once we have a result for queries to [S,<]2, we can obtain the same result for many different languages. We obtain easier proofs of old results and several new results. An earlier result we (...) have an easier proof of: the set of computable sets cannot be learned with queries to the language [+,<] . A new result: the set of computable sets cannot be learned with queries to the language [+,<,POWa] where POWa is the predicate that tests if a number is a power of a. (shrink)

In this paper I defend and develop Bernard Williams’ claim that the ‘constitutive thought’ of regret is ‘something like “how much better if it had been otherwise”’. An introductory section on cognitivist theories of emotion is followed by a detailed investigation of the concept of ‘agent-regret’ and of the ways in which the ‘constitutive thought’ might be articulated in different situations in which agents acknowledge casual responsibility for bringing about undesirable outcomes. Among problematic cases discussed are those in which (...) agents have caused harm through no fault of their own, or have been constrained to choose the lesser of two evils or to act against their moral values. R. Jay Wallace’s ‘bourgeois predicament’ and related cases, in which we recognize that our present advantages have flowed from regrettable antecedents, further show that regret is often not a simple emotion, and it is argued that conflicted regrets are sometimes unavoidable. Finally, the paper looks at Descartes’ account of regret as a form of sadness engendered by the recollection of irrecoverable happy experiences, to which the ‘constitutive thought’ does not readily apply. It is suggested that what Descartes is discussing is a different genre of emotion for which ‘nostalgia’ might be a better name. (shrink)

In “Revive and Refuse,” Marshall et al. (2024) argue that many individuals who are revived from opioid overdoses have diminished decision-making capacity (DMC), given that so many of them have opio...

I will here apply the classical Indian model of the dramatic actor as a methodology for interpreting the soteriological psychology of the Bhagavad Gītā, paying special attention to the usefulness of this approach for clarifying Kṛṣṇa's rationale in showing his divine form in Chapter 11. I argue that the Gītā advocates creative role-play as both the means and the end of liberation. Further, while Kṛṣṇa's teachings can be understood in terms of orthodox Hindu soteriologies that have in view an overcoming (...) of the emotions, I argue that Kṛṣṇa looks to transform Arjuna into an ‘athlete of emotion’, much like traditional Indian-based training methods do for theatrical actors.

This purely theoretical paper examines the relationship between the pursuit of entrepreneurial opportunity and environmental impact. Specifically, we attempt to more effectively define environmentally-relevant entrepreneurship through comparisons of different extant definitions in the literature, and to extend Schumpeterian theory through the inclusion of environmental entrepreneurship within his framework. By doing so, we contribute to the entrepreneurship literature through a more encompassing and specified definition of environmental entrepreneurship, and by incorporating environmental entrepreneurship into Schumpeter’s (1934) theoretical framework. We propose that (1) (...) Waste-Equals-Food, (2) Public Goods, and (3) Externalities each demonstrate thatenvironmental entrepreneurship is the act of creating future goods and services with positive environmental consequences. Finally, we assert that Schumpeter would likely characterize the pursuit of any such opportunity as “opening up a new source of supply.”. (shrink)

The statements and arguments based on experimental evidence used to support the claim that the 3d sub-level is below the 4s sub-level in scandium are examined. The flaw in all the arguments is that they assume the order in which the 3d and 4s sub-levels arrange remains the same in both the neutral atom and in its ions. Analysis of the ground and excited states of atomic spectra shows that as the number of electrons relative to the nuclear charge increases, (...) the 3d level moves higher in energy relative to the 4s level. It is perfectly possible that in a neutral scandium atom the 3d sub-level is above the 4s sub-level and that when it ionizes the energy levels simultaneously rearrange during the process. (shrink)

Terrorism is a notoriously plastic word, depending on user, audience, and political context. This paper focuses on shifts in its meanings since the early 1970s. As federal statutes made terrorism a criminal offense, common usage changed from a broad meaning to one that specified terrorism as a political crime. The argument is that the state shapes meaning and public discourse through law. Peircean semiotics and the semiotic philosophy of Russian linguist Vološinov provide a framework to explore relationships among politics, law, (...) and civil life. Applied to the events of September 11, 2001 such an analysis further allows better understanding of certain interpreters of the September 11 attacks, notably Jean Baudrillard, Jacques Derrida, and Jürgen Habermas.

This methodological essay describes and advocates using certain psychoanalytic techniques for ethnography. It focuses on the self analysis of the ethnographer using evenly hovering attention, dream analysis, and free association. It presents an argument that using those techniques enhances the goal of ethnography as a human science and of social research. Fear of crime serves as a point of departure for the methodological argument. Finally, it links psychoanalytic ethnography to a fractal model of society and the self with reference to (...) C. S. Peirce’s theory of semiotics as a link between the individual and society. (shrink)

Hird, G.R., Recursive properties of relations on models, Annals of Pure and Applied Logic 63 241–269. We prove general existence theorems for recursive models on which various relations have specified recursive properties. These capture common features of results in the literature for particular algebraic structures. For a useful class of models with new relations R, S, where S is r.e., we characterize those for which there is a recursive model isomorphic to on which the relation corresponding to S remains r.e., (...) while that corresponding to R is not r.e.; immune; hyperimmune. The results are applied to vector spaces, Boolean algebras and abelian groups. In the case of vector spaces, this leads to a new kind supermaximal subspace of V∞. (shrink)

In this paper, I use insights from post-structuralist anarchism to consider the relationship between a sense of the future, or “futurity”, and the notion of utopia for anarchist movements. At issue is whether anarchism requires a vision or sense of the future at all and, if so, whether that futurity should be utopian. Drawing from the post-structuralist anarchism of Todd May, Saul Newman, and Lewis Call, I consider the problems with utopia, as well as the potential irrelevance or impossibility of (...) even thinking the future. I then argue for the necessity of both and contend that post-structuralist anarchism does not preclude either futurity or provisional forms of utopia. I conclude by sketching the outlines of a utopia that would be acceptably post-structuralist and acceptably anarchist. (shrink)
