The covariant Klein-Gordon equation requires twice the boundary conditions of the Schrödinger equation and does not have an accepted single-particle interpretation. Instead of interpreting its solution as a probability wave determined by an initial boundary condition, this paper considers the possibility that the solutions are determined by both an initial and a final boundary condition. By constructing an invariant joint probability distribution from the size of the solution space, it is shown that the usual measurement probabilities can nearly be recovered (...) in the non-relativistic limit, provided that neither boundary constrains the energy to a precision near ℏ/t 0 (where t 0 is the time duration between the boundary conditions). Otherwise, deviations from standard quantum mechanics are predicted. (shrink)

The ability to focus on relevant information is central to human cognition. It is therefore hardly unsurprising that the notion of relevance appears across a range of different dis- ciplines. As well as its central role in relevance-theoretic pragmatics, for example, rele- vance is also a core concept in the affective sciences, where there is consensus that for a particular object or event to elicit an emotional state, that object or event needs to be relevant to the person in whom (...) that state is elicited. Despite this, although some affective scientists have carefully considered what emotional relevance might mean, surprisingly little research has been dedicated to providing a definition. Since, by contrast, the relevance-theoretic notion of relevance is carefully defined, our primary aim is to compare relevance as it exists in affective science and in relevance theory, A further aim is to redress what we perceive to be an imbalance: Affective scientists have made great strides in understanding the processes of emotion elicitation/responses etc., but despite the fact that among humans the communication of information about emotional states is ubiquitous, pragmatists have tended to ignore it. We conclude, therefore, that affective science and relevance theory have much to learn from each other. (shrink)

Historically, interjections have been treated in two different ways: as part of language, or as non-words signifying feelings or states of mind. In this paper, I assess the relative strengths and weaknesses of two contemporary approaches that reflect the historical dichotomy, and suggest a new analysis which preserves the insights of both. Interjections have a natural and a coded element, and are better analysed as falling at various points along a continuum between ‘showing’ and ‘saying’. These two notions are characterised (...) in theoretical terms, and some implications of the proposed approach are considered. (shrink)

A time-symmetric formulation of nonrelativistic quantum mechanics is developed by applying two consecutive boundary conditions onto solutions of a time- symmetrized wave equation. From known probabilities in ordinary quantum mechanics, a time-symmetric parameter P0 is then derived that properly weights the likelihood of any complete sequence of measurement outcomes on a quantum system. The results appear to match standard quantum mechanics, but do so without requiring a time-asymmetric collapse of the wavefunction upon measurement, thereby realigning quantum mechanics with an important (...) fundamental symmetry.

Grice (1957) drew a distinction between natural(N) and non–natural(NN) meaning, and showed how the latter might be characterised in terms of intentions and the recognition of intentions. Focussing on the role of natural signs and natural behaviours in communication, this paper makes two main points. First, verbal communication often involves a mixture of natural and non–natural meaning and there is a continuum of cases between showing and meaningNN. This suggests that pragmatics is best seen as a theory of intentional verbal (...) communication rather than a theory of meaningNN. Second, some natural behaviours have a signalling function: they are, in effect, natural codes. Such behaviours do not fit easily into Grice's distinction between natural and non–natural meaning, which suggests it is not exhaustive. (shrink)

Deirdre Wilson (2018)provides a reflective overview of a volume devoted to the historic application of relevance-theoretic ideas to literary studies. She maintains a view argued elsewhere that the putative non-propositional nature of (among other things) literary effects are an illusion, a view which dates to Sperber and Wilson (1986/1995: 224): “If you look at [non-propositional] affective effects through the microscope of relevance theory, you see a wide array of minute cognitive [i.e., propositional] effects.” This paper suggests an alternative, that modern-day (...) humans have two apparently different modes of expressing and interpreting information: one of these is a system in which propositional, cognitive effects dominate; the other involves direct, non-propositional effects. The paper concludes by describing two ways such affects might be assimilated into relevance theory. The first, to accept that humans are much more than merely cognitive organisms; the second, to rethink quite radically what we mean by cognition. (shrink)

A long-standing debate in social theory concerns the relative merits of structural approaches versus those that highlight the social actor. This article examines how various feminist approaches to gender inequality have incorporated assumptions about structure and agency, and suggests that existing perspectives could be improved by linking gender as a structural property of social organization and as a property of actors. Suggestions for an alternative conception of gender that acknowledges both dimensions of social life are discussed.

Although the path-integral formalism is known to be equivalent to conventional quantum mechanics, it is not generally obvious how to implement path-based calculations for multi-qubit entangled states. Whether one takes the formal view of entangled states as entities in a high-dimensional Hilbert space, or the intuitive view of these states as a connection between distant spatial configurations, it may not even be obvious that a path-based calculation can be achieved using only paths in ordinary space and time. Previous work has (...) shown how to do this for certain special states; this paper extends those results to all pure two-qubit states, where each qubit can be measured in an arbitrary basis. Certain three-qubit states are also developed, and path integrals again reproduce the usual correlations. These results should allow for a substantial amount of conventional quantum analysis to be translated over into a path-integral perspective, simplifying certain calculations, and more generally informing research in quantum foundations.

This article examines gay men’s efforts to break into the exclusive traditional fraternity institution by adopting the hegemonic model on their own terms. The authors examined to what extent members of a national gay fraternity, Delta Lambda Phi challenged or modified the entrenched fraternity culture that was hostile to homosexuals and whether they resisted or reproduced hegemonic masculinity in their efforts to redefine the meaning of college fraternities. This research examines gay fraternities in relation to two dimensions of hegemonic masculinity. (...) The authors explore how members of gay fraternities negotiated their stigmatized status among other men—that is, within the internal dimension of hegemonic masculinity. They explore the external dimension of hegemonic masculinity by analyzing how gay brothers, as men, related to all women. The authors further examine the connection between these two hegemonic dimensions and provide evidence showing how these two dimensions are coupled or disjointed. (shrink)

The combination in the “succession narrative” of completely plausible candor about the human and confidence in the sovereign involvement of the Lord, poses the question of providence in the most profound way possible.

Although we use randomness when we don’t know any better, a principle of indifference cannot be used to explain anything interesting or fundamental. For example, in thermodynamics it can be shown that the real explanatory work is being done by the Second Law, not the equal a priori probability postulate. But to explain the interesting Second Law, many physicists try to retreat to a “random explanation,” which fails. Looking at this problem from a different perspective reveals a natural solution: boundary-based (...) explanations that arguably should be viewed as no less fundamental than other physical laws.

This article analyzes how women in residential real estate sales interweave their work and family activities. It is presented as a case study of the effects of flexible scheduling on the tasks of managing paid and domestic work. Women are attracted to real estate sales because they perceive that it will enable them to combine their paid and unpaid labor in a relatively comfortable way as a result of the flexibility of setting their own work schedules. They find that the (...) work requires long hours and significant adaptations in the division of household labor. The findings demonstrate that flexibility itself is not adequate for accomodating the demands of families and wage work. Additional changes in the organization of both types of work, as well as ideological changes in the ownership of family-related tasks are required to alleviate the difficulties women face in integrating family and work responsibilities.

Three recent reports (1–3) identify two genes, thick veins (tkv) and saxophone (sax), which encode serine/threonine transmembrane proteins that act as receptors for mediating different aspects of the Drosophila TGF‐β‐related signal, dpp. tkv is required for patterning the entire embryonic dorsal region, while sax is required for patterning only amnioserosa, the dorsalmost cell fates. dpp signaling in other developmental processes again requires both tkv and sax, but to differing degrees. tkv and sax, encode type I receptors, which appear to directly (...) bind ligand, unlike what has been observed for other type I receptors.

If Abraham is on the road again in the Christian movement, he will provoke preachers to think unaccustomed thoughts, and listeners will recapture something of the Abrahamic character of the Christian journey with God through real history.

There is no mistaking the fact that the narrative traditions of the Old Testament expect to find a hearing among people prepared to recognize their own story in what is told and to see their own times as a direct extension of the same story.

In lieu of an abstract, here is a brief excerpt of the content:Tacitus’ Tiberius: The State of the Evidence for the Emperor’s Ipsissima Verba in the AnnalsDavid B. WhartonRonald Syme first proposed that the style and vocabulary of some of the speeches attributed to Tiberius in the Annals were strongly influenced by those actually uttered by the Emperor, as preserved in the acta senatus. Syme said,Tacitus’ vocabulary was liable to be influenced. Certain “Tiberian” words occur in the speeches, recur in (...) the hexad and never again. Thus compello, diiudico, exsatio.... To render Tiberius, Tacitus made a careful choice of words, not only the rare and arresting, but also less obtrusive words, alien from his own manner. 1Syme also suggested (700) that the speeches of Tiberius display a higher frequency of abstract nouns of a Ciceronian type, and of compound verbs.Although Syme never actually tried to test his hypothesis, N. P. Miller did, and published her results in 1968’s American Journal of Philology. In “Tiberius Speaks” she compares the number of “solitaries” (that is, words that appear only once in the extant Tacitean corpus) occurring in the speeches, both recta and obliqua, attributed to Tiberius, with the number occurring in the speeches attributed to Nero. She concludes, “... we may... with some reason postulate that the high proportion of Tiberian solitaries indicates a connection with Tiberius’ [actual] speeches” (19).Although Syme’s and Miller’s hypothesis has not been universally accepted, neither has it ever been fully rejected, and it has continued to haunt a small corner of Tacitean scholarship. All subsequent opinion on the subject, moreover, has assumed at least that Miller’s evidence is [End Page 119] valid, even if her conclusions are not. 2 I wish to show here, however, that Miller’s methodology in “Tiberius Speaks” is flawed, and that there are absolutely no stylometric data in support of the theory.I begin with a review of Miller’s data. Table 1 is from her 1968 article, in which she compares solitaries from those books of the Annals covering the principates of the emperors Tiberius (books 1–3) and Nero (books 13–16). Miller comments,Table 1. Solitaries in the AnnalsBook123Total13141516Total1. No. of solitaries526262176485681322172. No. with reference to the Emperor7592155114253. % of 1 accounted for by 213814121091312114. No. of 2 appearing in Emperor’s speeches35715132065. % of 2 accounted for by 4431007871206018024The really interesting figures are those under four and five. Neither individual books nor the two blocks of books differ significantly in the number of solitaries which they contain, or which have direct reference to the Emperor. But they differ both in the number and percentage of the solitaries which appear in the Emperor’s speeches. Because more of the Tiberian solitaries come from Tiberius himself?(19)[End Page 120]Miller’s data do seem to support the notion that solitaries appear in the speeches of Tiberius with much greater frequency than they do in the speeches of Nero. In fact, she could have made her comparison clearer by leaving out the “emperor-referring” category entirely, and simply comparing the number of solitaries in the speeches to the total number of solitaries in the relevant books. In the Tiberian books, using her own data, 8.5% of all the solitaries appear in Tiberius’ speeches, as opposed to a meager 2.7% appearing in Nero’s speeches. By either analysis, there is a roughly threefold difference in the frequency of solitaries.Unfortunately, Miller has failed to account for the difference in the total amount of speech attributed to each emperor. Tiberius has, in fact, nearly three times as many lines of speech, recta and obliqua, as does Nero. Using Miller’s own data, it is possible to devise a more accurate and straightforward frequency test, simply comparing the total number of lines spoken in the speeches to the number of solitaries occurring in them...

The best case for thinking that quantum mechanics is nonlocal rests on Bell's Theorem, and later results of the same kind. However, the correlations characteristic of Einstein–Podolsky–Rosen (EPR)–Bell (EPRB) experiments also arise in familiar cases elsewhere in quantum mechanics (QM), where the two measurements involved are timelike rather than spacelike separated; and in which the correlations are usually assumed to have a local causal explanation, requiring no action-at-a-distance (AAD). It is interesting to ask how this is possible, in the light (...) of Bell's Theorem. We investigate this question, and present two options. Either (i) the new cases are nonlocal too, in which case AAD is more widespread in QM than has previously been appreciated (and does not depend on entanglement, as usually construed); or (ii) the means of avoiding AAD in the new cases extends in a natural way to EPRB, removing AAD in these cases too. There is a third option, viz., that the new cases are strongly disanalogous to EPRB. But this option requires an argument, so far missing, that the physical world breaks the symmetries which otherwise support the analogy. In the absence of such an argument, the orthodox combination of views—action-at-a-distance in EPRB, but local causality in its timelike analogue—is less well established than it is usually assumed to be. 1 Introduction1.1 Background1.2 Outline of the argument2 The Experiments2.1 Standard EPRB2.2 Sideways EPRB2.3 Comparing the experiments2.4 The need for beables3 The Symmetry Considerations3.1 The action symmetry3.2 Time-symmetry in SEPRB4 The Basic Trilemma4.1 An intuitive defence of Option III?5 Avoiding the Trilemma?6 The Classical Objection7 Defending Option III7.1 The free will argument7.2 Independence and consistency8 Entanglement and Epistemic Perspective.

A 2015 experiment by Hanson and Delft colleagues provided further confirmation that the quantum world violates the Bell inequalities, being the first Bell test to close two known experimental loopholes simultaneously. The experiment was also taken to provide new evidence of ‘spooky action at a distance’. Here we argue for caution about the latter claim. The Delft experiment relies on entanglement swapping, and our main claim is that this geometry introduces an additional loophole in the argument from violation of the (...) Bell inequalities to action at a distance: the apparent action at a distance may be an artifact of ‘collider bias’. In the absence of retrocausality, the sensitivity of such experiments to this ‘Collider Loophole’ depends on the temporal relation between the entanglement swapping measurement C and the two measurements A and B between which we seek to infer a causal connection. CL looms large if the C is in the future of A and B, but not if C is in the past. The Delft experiment itself is the intermediate case, in which the separation is spacelike. We argue that this leaves it vulnerable to CL, unable to establish conclusively that it avoids it. (shrink)

A central diagnostic and anecdotal feature ofautismis difficulty with socialcommunication. We take the position that communication is a two-way,intersubjectivephenomenon—as described by thedouble empathy problem—and offer uprelevance theory(a cognitive account of utterance interpretation) as a means of explaining such communication difficulties. Based on a set of proposed heuristics for successful and rapid interpretation of intended meaning, relevance theory positions communication as contingent on shared—and, importantly,mutuallyrecognized—“relevance.” Given that autistic and non-autistic people may have sometimes markedly different embodied experiences of the world, we (...) argue that what is most salient to each interlocutor may be mismatched. Relevance theory would predict that where this salient information is not (mutually) recognized or adjusted for, mutual understanding may be more effortful to achieve. This paper presents the findings from a small-scale, linguistic ethnographic study of autistic communication featuring eight core autistic participants. Each core autistic participant engaged in three naturalistic conversations around the topic of loneliness with: (1) a familiar, chosen conversation partner; (2) a non-autistic stranger and (3) an autistic stranger. Relevance theory is utilized as a frame for the linguistic analysis of the interactions. Mutual understanding was unexpectedly high across all types of conversation pairings. In conversations involving two autistic participants, flow, rapport and intersubjective attunement were significantly increased and in three instances, autistic interlocutors appeared to experience improvements in their individual communicative competence contrasted with their other conversations. The findings have the potential to guide future thinking about how, in practical terms, communication between autistic and non-autistic people in both personal and public settings might be improved.

The path integral is not typically utilized for analyzing entanglement experiments, in part because there is no standard toolbox for converting an arbitrary experiment into a form allowing a simple sum-over-history calculation. After completing the last portion of this toolbox (a technique for implementing multi-particle measurements in an entangled basis), some interesting 4- and 6-particle experiments are analyzed with this alternate technique. While the joint probabilities of measurement outcomes are always equivalent to conventional quantum mechanics, differences in the calculations motivate (...) a number of foundational insights, concerning nonlocality, retrocausality, and the objectivity of entanglement itself.

Critical cellular functions, including stem cell maintenance, fate determination, and cellular behavior, are governed by canonical Wnt signaling, an evolutionarily conserved pathway whose intracellular signal is transduced by β‐catentin. Emerging evidence suggests that canonical Wnt signaling influences cellular aging, indicating that increases in Wnt signaling delay age‐related deficits.1 However, recent Science papers suggest that Wnt signaling accelerates the onset of aging.2,3 In an attempt to resolve this paradox and clarify how Wnt signaling affects aging, we provide a selective review of (...) research relevant to Wnt signaling and aging.
