Aspectuo-Temporal Underspecification in Anindilyakwa: Descriptive, Theoretical, Typological and Quantitative Issues

So-called ‘zero’ or ‘null’ tenses have often been characterized as functionally deficient forms, deprived of any inherent content. In this paper, we will focus on the semantics of a morpho-phonologically null inflectional verbal paradigm in Anindilyakwa (Groote Eylandt, N.T., Australia, which is both temporally and aspectually underspecified. Through a quantitative corpus study conducted in the paper, we establish that ‘zero inflection’ in this language, contra prior works on such tenses in general (e.g. Bybee 1990) and in Anindilyakwa in particular (Bednall 2019), presents various degrees of sensitivity to traditional Vendlerian aspectual parameters. We show that while telicity is not a significant predictor for the temporal interpretation of zero-inflected Anindilyakwa verbs, and dynamicity is a good but not very good predictor, only a very broad opposition between change-of-state (including qua boundedness) and non-change-of-state, or perfective/imperfective, gives very significant biases towards past vs. present anchoring. We also show that atomic telicity is the only categorical Aktionsart predictor for temporal anchoring in this context correctly predict the temporal anchoring of such verbs, and stativity is not biased towards present interpretations, thereby questioning currently received typological theories of the semantics of so-called ‘zero-tenses’ / aspectuo-temporally underspecified tenses.

Temporal adverbial superlatives in Dutch

This paper investigates adverbial superlative expressions in Dutch that have a temporal interpretation, i.e. that contain the forms eerst ‘first’, laatst ‘latest’, and vroegst ‘earliest’. I focus on possessive superlatives and superlatives embedded under the preposition voor. Although both constructions contain bare superlatives and are interpreted temporally, they represent semantically and pragmatically different readings, and attach to the sentence in structurally different ways. I present a semantic analysis of both types of superlatives, and I show what this entails for how time adverbials interact with superlatives.

Temporally Underspecified Bare Clauses in Mandarin

This study shows that the temporal interpretation of Mandarin bare clauses is fully underspecified when these clauses describe scheduled, preprogrammed events. The paper defines the key syntactic properties of such bare clauses and their context of use. On the basis of this definition, the paper proposes that these clauses are copular constructions, which in all relevant respects behave like regular copular constructions. Bare clauses contain a subject and a predicate, related by the (sometimes covert) copula shì, expressing a paired relation between them. The fact that bare clauses have a simple predicative structure underlyingly is further supported by observations from the realm of gapping and negation. Crucially, it is proposed that there is no temporal projection immediately above the verb phrase in these sentences. The underspecification of the temporal interpretation is accordingly accounted for.

Factorization à la Dirac Applied to Some Equations of Classical Physics

In this paper, we present an application of Dirac’s factorization method to three types of the partial differential equations, i.e., the wave equation, the scattering equation, and the telegrapher’s equation. This method gives results that contribute to a better understanding of physical phenomena by generalizing the Euler and constituent equations. Its application to the wave equation shows that it is indeed a factorization method, since it gives d’Alembert’s solutions in a more general framework. In the case of the diffusion equation, a fractional differential equation has been established that has already been highlighted by other authors in particular cases, but by indirect methods. Dirac’s method brings several new results in the case of the telegraphers’ equation corresponding to the propagation of an acoustic wave in a dissipative fluid. On the one hand, its formalism facilitates the temporal interpretation of phenomena, in particular the density and compressibility of the fluid become temporal operators, which can be “seen” as susceptibilities of the fluid. On the other hand, a consequence of this temporal modeling is the highlighting in Euler’s equation of a term similar to the one that was introduced by Boussinesq and Basset in the equation of the motion of a solid sphere in a unsteady fluid.

Non-canonical word order and temporal reference in Vietnamese

The paper revisits Duffield’s (2007) (Duffield, Nigel. 2007. Aspects of Vietnamese clausal structure: Separating tense from assertion. Linguistics 45(4). 765–814) analysis of the correlation between the position of a ‘when’-phrase and the temporal reference of a bare sentence in Vietnamese. Bare sentences in Vietnamese, based on (Smith, Carlota S. & Mary S. Erbaugh. 2005. Temporal interpretation in Mandarin Chinese. Linguistics 43(4). 713–756), are argued to obtain their temporal interpretation from their aspectual composition, and the default temporal reference: bounded events are located in the past, unbounded events at present. It is shown that the correlation so observed in when-questions is superficial, and is tied to the syntax and semantics of temporal modification and the requirement that temporal adverbials denoting future time is base generated in sentence-initial position, and past time adverbials in sentence-final position. A ‘when’-phrase, being temporally underspecified, obtains its temporal value from its base position. However, the correlation between word order and temporal reference in argument wh-questions and declaratives is factual, depending on whether the predicate-argument configuration allows for a telic interpretation or not. To be specific, it is dependent on whether the application of Generic Modification (Snyder, William. 2012. Parameter theory and motion predicates. In Violeta Demonte & Louise McNally (eds.), Telicity, change, and state. Acrosscategorial view of event structure, 279–299. Oxford: Oxford University Press) or accomplishment composition is realized. Canonical declaratives, and argument wh-questions, with telicity inducing material, license GM or accomplishment composition, yielding bounded events, hence past; by contrast, their non-canonical counterparts block GM or accomplishment composition, giving rise to unbounded event descriptions, hence non-past.

Prevalence Threshold and Temporal Interpretation of Screening Tests: The Example of the SARS-CoV-2 (COVID-19) Pandemic

The curvilinear relationship between a screening test's positive predictive value (PPV) and its target disease prevalence is proportional. In consequence, there is an inflection point of maximum curvature in the screening curve defined as a function of the sensitivity and specificity beyond which the rate of change of a test's PPV declines sharply relative to disease prevalence. Herein, we demonstrate a mathematical model exploring this phenomenon and define the prevalence threshold point where this change occurs. Understanding where this prevalence point lies in the curve has important implications for the interpretation of test results, the administration of healthcare systems, the implementation of public health measures, and in cases of pandemics like SARS-CoV-2, the functioning of society at large. To illustrate the methods herein described, we provide the example of the screening strategies used in the SARS-CoV-2 (COVID-19) pandemic, and calculate the prevalence threshold statistic of different tests available today. This concept can help contextualize the validity of a screening test in real time, thereby enhancing our understanding of the dynamics of the current pandemic.

Pragmatic Aspects of Tense in English and Arabic: Based on a Neo-SRE Theory

The hypothesis upon which this paper is based is that in both Arabic and English the notion of tense underdetermines the notion of time, and some pragmatic enrichment is needed to the get at the correct temporal interpretation. In both languages, beside the normal unmarked tense usages, some marked usages of tense are available wherein the tense constructions do not refer to their equivalent temporal intervals; this is done for the sake of rhetorical purposes as illustrated and exemplified. Even the unmarked cases to tense are proven to require, for sound interpretation, the inclusion of pragmatic givens. Many examples are given in both languages showing the pragmatic nature of the temporal interpretive process of tense in terms of the SRE theory where the interrelationship of the three-time intervals speech, event, and reference times (S/TU, E/TSit, R/TT) is based primarily on rather pragmatic parameters within the process of temporal interpretation. Some new treatment is given concerning the theory of tense interpretation which is related to a pragmatic conception of the speaker’s temporal projection or “virtuality” via which tenses’ inherent three-time points are pragmatically interrelated and arranged in terms of the potential existence of multiple virtual and non-virtual speakers.

Introduction

This introductory chapter shows how Niccolò Machiavelli's account of a new Rome points to the tremendous impact that he believes Christianity has had and can have on politics. In order to overcome the politically deleterious consequences of Christianity and the pagan beliefs that engendered it, as well as to forestall the rise of another tyranny of its magnitude, Machiavelli appeals to certain Christian doctrines to support his vision of an earthly discipline that exercises the strength that he views as essential to sustain political life. In so doing, he creates a wholly temporal interpretation of Christianity. Furthermore, the argument that he infuses his presentation of Livy's Rome with a temporal form of Christianity that can fortify political life allows this chapter to account for several otherwise puzzling and controversial features of Machiavelli's work. His many changes in Livy's history can be seen as a conscious—indeed, an acknowledged—attempt to mask his innovations as a recourse to antiquity. His divergences from Livy reveal an innovation that, if successful, will establish a new epoch.
