2008. Pruning Some Branches from 'Branching Spacetimes'
CHAPTER 10 Pruning Some Branches from “Branching Spacetimes” John Earman* Abstract Discussions of branching time and branching spacetime have become com- mon in the philosophical literature. If properly understood, these concep- tions can be harmless. But they are sometimes used in the service of debat- able and even downright pernicious doctrines. The purpose of this chapter is to identify the pernicious branching and prune it back. 1. INTRODUCTION Talk of “branching time” and “branching spacetime” is wide spread in the philo- sophical literature. Such expressions, if properly understood, can be innocuous. But they are sometimes used in the service of debatable and even downright per- nicious doctrines. The purpose of this paper is to identify the pernicious branching and prune it back. Section 2 distinguishes three types of spacetime branching: individual branch- ing, ensemble branching, and Belnap branching. Individual branching, as the name indicates, involves a branching structure in individual spacetime models. It is argued that such branching is neither necessary nor sufficient for indeterminism, which is explicated in terms of the branching in the ensemble of spacetime mod- els satisfying the laws of physics. Belnap branching refers to the sort of branching used by the Belnap school of branching spacetimes. An attempt is made to sit- uate this sort of branching with respect to ensemble branching and individual branching. Section 3 is a sustained critique of various ways of trying to imple- ment individual branching for relativistic spacetimes. Conclusions are given in Section 4. * Department of History and Philosophy of Science, University of Pittsburgh, Pittsburgh, USA The Ontology of Spacetime II © Elsevier BV ISSN 1871-1774, DOI: 10.1016/S1871-1774(08)00010-7 All rights reserved 187 188 Pruning Some Branches from “Branching Spacetimes” 2. -
Layers and Operators in Lakota1 Avelino Corral Esteban Universidad Autónoma De Madrid
Kansas Working Papers in Linguistics, Vol. 36 (2015), 1-33 Layers and operators in Lakota1 Avelino Corral Esteban Universidad Autónoma de Madrid Abstract Categories covering the expression of grammatical information such as aspect, negation, tense, mood, modality, etc., are crucial to the study of language universals. In this study, I will present an analysis of the syntax and semantics of these grammatical categories in Lakota within the Role and Reference Grammar framework (hereafter RRG) (Van Valin 1993, 2005; Van Valin and LaPolla 1997), a functional approach in which elements with a purely grammatical function are treated as ´operators`. Many languages mark Aspect-Tense- Mood/Modality information (henceforth ATM) either morphologically or syntactically. Unlike most Native American languages, which exhibit an extremely complex verbal morphological system indicating this grammatical information, Lakota, a Siouan language with a mildly synthetic / partially agglutinative morphology, expresses information relating to ATM through enclitics, auxiliary verbs and adverbs, rather than by coding it through verbal affixes. 1. Introduction The organisation of this paper is as follows: after a brief account of the most relevant morpho- syntactic features exhibited by Lakota, Section 2 attempts to shed light on the distinction between lexical words, enclitics and affixes through evidence obtained in the study of this language. Section 3 introduces the notion of ´operator` and explores the ATM system in Lakota using RRG´s theory of operator system. After a description of each grammatical category, an analysis of the linear order exhibited by the Lakota operators with respect to the nucleus of the clause are analysed in Section 4, showing that this ordering reflects the scope relations between the grammatical categories conveyed by these operators. -

LINGUISTICS 221 Lecture #3 DISTINCTIVE FEATURES Part 1. An utterance is composed of a sequence of discrete segments. Is the segment indivisible? Is the segment the smallest unit of phonological analysis? If it is, segments ought to differ randomly from one another. Yet this is not true: pt k prs What is the relationship between members of the two groups? p t k - the members of this set have an internal relationship: they are all voiceles stops. p r s - no such relationship exists p b d s bilabial bilabial alveolar alveolar stop stop stop fricative voiceless voiced voiced voiceless SIMILARITIES AND DIFFERENCES! Segments may be viewed as composed of sets of properties rather than indivisible entities. We can show the relationship by listing the properties of each segment. DISTINCTIVE FEATURES • enable us to describe the segments in the world’s languages: all segments in any language can be characterized in some unique combination of features • identifies groups of segments → natural segment classes: they play a role in phonological processes and constraints • distinctive features must be referred to in terms of phonetic -- articulatory or acoustic -- characteristics. 1 Requirements on distinctive feature systems (p. 66): • they must be capable of characterizing natural segment classes • they must be capable of describing all segmental contrasts in all languages • they should be definable in phonetic terms The features fulfill three functions: a. They are capable of describing the segment: a phonetic function b. They serve to differentiate lexical items: a phonological function c. They define natural segment classes: i.e. those segments which as a group undergo similar phonological processes. -
Definiteness and Determinacy
Linguistics and Philosophy manuscript No. (will be inserted by the editor) Definiteness and Determinacy Elizabeth Coppock · David Beaver the date of receipt and acceptance should be inserted later Abstract This paper distinguishes between definiteness and determinacy. Defi- niteness is seen as a morphological category which, in English, marks a (weak) uniqueness presupposition, while determinacy consists in denoting an individual. Definite descriptions are argued to be fundamentally predicative, presupposing uniqueness but not existence, and to acquire existential import through general type-shifting operations that apply not only to definites, but also indefinites and possessives. Through these shifts, argumental definite descriptions may become either determinate (and thus denote an individual) or indeterminate (functioning as an existential quantifier). The latter option is observed in examples like `Anna didn't give the only invited talk at the conference', which, on its indeterminate reading, implies that there is nothing in the extension of `only invited talk at the conference'. The paper also offers a resolution of the issue of whether posses- sives are inherently indefinite or definite, suggesting that, like indefinites, they do not mark definiteness lexically, but like definites, they typically yield determinate readings due to a general preference for the shifting operation that produces them.

Serial Verb Constructions Revisited: a Case Study from Koro
Serial Verb Constructions Revisited: A Case Study from Koro By Jessica Cleary-Kemp A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Linguistics in the Graduate Division of the University of California, Berkeley Committee in charge: Associate Professor Lev D. Michael, Chair Assistant Professor Peter S. Jenks Professor William F. Hanks Summer 2015 © Copyright by Jessica Cleary-Kemp All Rights Reserved Abstract Serial Verb Constructions Revisited: A Case Study from Koro by Jessica Cleary-Kemp Doctor of Philosophy in Linguistics University of California, Berkeley Associate Professor Lev D. Michael, Chair In this dissertation a methodology for identifying and analyzing serial verb constructions (SVCs) is developed, and its application is exemplified through an analysis of SVCs in Koro, an Oceanic language of Papua New Guinea. SVCs involve two main verbs that form a single predicate and share at least one of their arguments. In addition, they have shared values for tense, aspect, and mood, and they denote a single event. The unique syntactic and semantic properties of SVCs present a number of theoretical challenges, and thus they have invited great interest from syntacticians and typologists alike. But characterizing the nature of SVCs and making generalizations about the typology of serializing languages has proven difficult. There is still debate about both the surface properties of SVCs and their underlying syntactic structure. The current work addresses some of these issues by approaching serialization from two angles: the typological and the language-specific. On the typological front, it refines the definition of ‘SVC’ and develops a principled set of cross-linguistically applicable diagnostics. -
Branching Time and the Semantics of Future Contingents
Branching Time and the Semantics of Future Contingents Jacek Wawer PhD dissertation prepared under the supervision of Prof. dr hab. Tomasz Placek Institute of Philosophy Jagiellonian University Kraków, Poland Acknowledgments First and foremost, I would like to express my gratitude to Professor Tomasz Placek, the supervisor of my dissertation. Over a decade ago, he introduced me to the world of branching and has helped me to travel it ever since. The assistance he provided during my work cannot be overestimated. The philosophical community was impoverished due to his dedication, but I benefited enormously. Also, thanks to his continuous sup- port, I had the best possible environment to develop my thought. I have never been an obedient student and often challenged, rather than developed his philosophical views. Nonetheless, he only doubled his support and helped me to express my views better than I could have done it myself. I count myself to be immensely lucky to be his student. I would like to thank Professors Fabrice Correia, John MacFarlane, and Thomas Müller who mentored me during my research visits in Geneva, Berkeley, and Konstanz respectively. Many of their helpful suggestions influenced my views. I am indebted to Alex Malpass, Leszek Wronski,´ Juliusz Doboszewski, Antje Rumberg, and Michał Marczyk for their feedback on various fragments of this work and many inspiring dis- cussions which helped me clarify my ideas and recognize new paths. I would have not accomplished this work, if not for the continuous support and encouragement of my wife, Karolina. My research was possible due to the financial, administrative, and scientific sup- port of many institutions. -
1 English Subjectless Tagged Sentences Paul Kay Department Of
1 English subjectless tagged sentences Paul Kay Department of Linguistics University of California Berkeley, CA 94720 [email protected] 2 Abstract A colloquial English sentence like Fooled us, didn't they? contains a finite main verb but no expressed subject. The identity of the missing subject of fooled is recovered from the tag subject they: compare Fooled us, didn't she?, Fooled us, didn't you? This paper argues (1) that such subjectless tagged sentences (STSs) pose a problem for grammatical approaches based on movement and empty categories and (2) that STSs receive a revealing analysis as part of a finely articulated family of tagged sentence constructions when viewed within a non-derivational, constructional, multiple-inheritance-based approach.* *I would like to thank Peter Culicover, Liliane Haegeman, Charles Fillmore Andreas Kathol and Richard Oehrle for comments on previous versions of this paper, as well as an anonymous reviewer for Language. They have doubtless offered more good advice than I have accepted. 3 0. Introduction. It has been argued from several points of view that whatever can be done with empty categories (ecs) can be done without them (Ades and Steedman 1982, Gazdar et al. 1984, Kaplan and Zaenen 1989, Pollard and Sag 1994 chapter 9, Sag and Fodor 1994, Kay and Fillmore 1999, Sag 1999). It has also been argued that, because there is no hard evidence for their existence, linguistic theory would be better off dispensing with these unobservable entities (Pickering and Barry 1991, Sag and Fodor 1994, Sag 1999).1 The present paper purports to take the argument one step further by showing that there are things that can be done without empty categories that cannot be done with them, at least not with any of the ecs currently available. -
The Syntax of Answers to Negative Yes/No-Questions in English Anders Holmberg Newcastle University
The syntax of answers to negative yes/no-questions in English Anders Holmberg Newcastle University 1. Introduction This paper will argue that answers to polar questions or yes/no-questions (YNQs) in English are elliptical expressions with basically the structure (1), where IP is identical to the LF of the IP of the question, containing a polarity variable with two possible values, affirmative or negative, which is assigned a value by the focused polarity expression. (1) yes/no Foc [IP ...x... ] The crucial data come from answers to negative questions. English turns out to have a fairly complicated system, with variation depending on which negation is used. The meaning of the answer yes in (2) is straightforward, affirming that John is coming. (2) Q(uestion): Isn’t John coming, too? A(nswer): Yes. (‘John is coming.’) In (3) (for speakers who accept this question as well formed), 1 the meaning of yes alone is indeterminate, and it is therefore not a felicitous answer in this context. The longer version is fine, affirming that John is coming. (3) Q: Isn’t John coming, either? A: a. #Yes. b. Yes, he is. In (4), there is variation regarding the interpretation of yes. Depending on the context it can be a confirmation of the negation in the question, meaning ‘John is not coming’. In other contexts it will be an infelicitous answer, as in (3). (4) Q: Is John not coming? A: a. Yes. (‘John is not coming.’) b. #Yes. In all three cases the (bare) answer no is unambiguous, meaning that John is not coming. -
Sequence-Of-Tense and the Features of Finite Tenses Karen Zagona University of Washington*
Sequence-of-tense and the Features of Finite Tenses Karen Zagona University of Washington* Abstract Sequence-of-tense (SOT) is often described as a (past) tense verb form that does not correspond to a semantically interpretable tense. Since SOT clauses behave in other respects like finite clauses, the question arises as to whether the syntactic category Tense has to be distinguished from the functional category tense. I claim that SOT clauses do in fact contain interpretable PRESENT tense. The “past” form is analyzed as a manifestation of agreement with the (matrix past) controller of the SOT clause evaluation time. One implication of this analysis is that finite verb forms should be analyzed as representing features that correspond to functional categories higher in clause structure, including those of the clausal left periphery. SOT morphology then sheds light on the existence of a series of finer- grained functional heads that contribute to tense construal, and to verbal paradigms. These include Tense, Modality and Force. 1. Introduction The phenomenon of sequence-of-tense (SOT) poses several challenges for the standard assumption that a “past tense” verb form signals the presence of a functional category in clause structure with an interpretable ‘past’ value. SOT is illustrated by the ‘simultaneous’ reading of sentence (1): (1) Terry believed that Sue was pregnant. a. The time of Sue’s pregnancy precedes time of Terry’s belief (precedence) b. The time of Sue’ pregnancy overlaps time of Terry’s belief (simultaneity) For the ‘precedence’ reading in (1a), the embedded clause tense is semantically transparent in the sense that the past form was corresponds to a past ordering relation (relative to the time of Terry’s belief). -
