(2012) Perspectival Discourse Referents for Indexicals* Maria
To appear in Proceedings of SULA 7 (2012) Perspectival discourse referents for indexicals* Maria Bittner Rutgers University 0. Introduction By definition, the reference of an indexical depends on the context of utterance. For ex- ample, what proposition is expressed by saying I am hungry depends on who says this and when. Since Kaplan (1978), context dependence has been analyzed in terms of two parameters: an utterance context, which determines the reference of indexicals, and a formally unrelated assignment function, which determines the reference of anaphors (rep- resented as variables). This STATIC VIEW of indexicals, as pure context dependence, is still widely accepted. With varying details, it is implemented by current theories of indexicali- ty not only in static frameworks, which ignore context change (e.g. Schlenker 2003, Anand and Nevins 2004), but also in the otherwise dynamic framework of DRT. In DRT, context change is only relevant for anaphors, which refer to current values of variables. In contrast, indexicals refer to static contextual anchors (see Kamp 1985, Zeevat 1999). This SEMI-STATIC VIEW reconstructs the traditional indexical-anaphor dichotomy in DRT. An alternative DYNAMIC VIEW of indexicality is implicit in the ‘commonplace ef- fect’ of Stalnaker (1978) and is formally explicated in Bittner (2007, 2011). The basic idea is that indexical reference is a species of discourse reference, just like anaphora. In particular, both varieties of discourse reference involve not only context dependence, but also context change. The act of speaking up focuses attention and thereby makes this very speech event available for discourse reference by indexicals. Mentioning something likewise focuses attention, making the mentioned entity available for subsequent dis- course reference by anaphors. -
Precision Guidance Needed for Metalworking Machinery That
Precision guidance needed for metalworking machinery that automatically grinds 40,000 sinks every year https://www.hepcomotion.com/case-studies/precision-guidance-needed-for-metalworking-machinery-that- automatically-grinds-40000-sinks-every-year/ INDUSTRY PRODUCT COUNTRY PROCESS GV3 - V Linear Manufacturing Germany Grinding Guide System Peitzmeier Maschinenbau machine builders based in Germany specialise in the construction of grinding machines. Their latest invention, the Omni-Grind Twin 3100 AC, enables automated grinding and polishing of workpieces in the metalworking industry. The machine builder relies on HepcoMotion’s GV3 guidance to prevent damage to the steel during processing; the linear guide system enables precise alignment of the grinding tool in the range of hundredths of a millimetre. The challenge: A major customer wants to precision grind 40,000 stainless steel sinks per year Among the users of Peitzmeier’s grinding machines is a Dutch manufacturer, who processes stainless steel sinks for a Swiss company. The design of the grinding machine had some challenging requirements, as Ulrich Peitzmeier, Managing Director of Peitzmeier explains: “The three-ton plant needed to be capable of grinding 40,000 sinks per year with extra care – the sinks are made from sheet metal just one millimetre thick. If a tool takes too long grinding material in one place, it can very quickly damage the workpiece.” Peitzmeier had to adapt their grinding machine to meet these requirements. The heavy grinding tool, usually mounted on a double-stranded U-rail, had to be replaced in favour of a lighter tool that could be aligned more precisely on just a single guide rail. -

CHAPTER 2- ABRASIVE GRINDING PROCESSES. LEARNING OBJECTIVES D Understand the types of different grinding machines D Techniques of grinding D Various application of grinding machines -------------------------------------------------------------------------------------------------------------------- Classification of Grinding Processes. Grinding machines can be best classified according to the type of surfaces they are used to produce. In order to bring the job to the required shape, size and surface finish the surplus stock is removed either by feeding the job against the revolving wheel or by forcing the revolving wheel against the job. Conventional grinding machines can be broadly classified as Surface grinding machine Cylindrical grinding machine Internal grinding machine Tool and cutter grinding machine SURFACE GRINDING MACHINE Basically there are four different types of surface grinding machines characterised by the movement of their tables and the orientation of grinding wheel spindles as follows: Horizontal spindle & reciprocating table Vertical spindle & reciprocating table Horizontal spindle & rotary table Vertical spindle & rotary table Figure 1: Horizontal spindle and reciprocating table Complied by: Jagdeesha T, Assistant Professor, Mech Engg Dept., National Institute of Technology, Calicut Figure 2: a) Transverse Grinding b) Plunge Grinding Vertical Spindle reciprocating table grinder This grinding machine with all working motions is shown in Fig. 3a. The grinding operation is similar to that of face milling on a vertical milling machine. In this machine a cup shaped wheel grinds the workpiece over its full width using end face of the wheel as shown in Fig 3b. This brings more grits in action at the same time and consequently a higher material removal rate may be attained than for grinding with a peripheral wheel. -
Prosodic Focus∗
Prosodic Focus∗ Michael Wagner March 10, 2020 Abstract This chapter provides an introduction to the phenomenon of prosodic focus, as well as to the theory of Alternative Semantics. Alternative Semantics provides an insightful account of what prosodic focus means, and gives us a notation that can help with better characterizing focus-related phenomena and the terminology used to describe them. We can also translate theoretical ideas about focus and givenness into this notation to facilitate a comparison between frameworks. The discussion will partly be structured by an evaluation of the theories of Givenness, the theory of Relative Givenness, and Unalternative Semantics, but we will cover a range of other ideas and proposals in the process. The chapter concludes with a discussion of phonological issues, and of association with focus. Keywords: focus, givenness, topic, contrast, prominence, intonation, givenness, context, discourse Cite as: Wagner, Michael (2020). Prosodic Focus.

Thanks also for in-depth comments on an earlier version of this chapter by Dan Goodhue and Lisa Matthewson, and two reviewers; I am also indebted to several discussions of focus issues with Aron Hirsch, Bernhard Schwarz, and Ede Zimmermann (who frequently wanted coffee) over the years. -
Against Logical Form
Against logical form Zolta´n Gendler Szabo´ Conceptions of logical form are stranded between extremes. On one side are those who think the logical form of a sentence has little to do with logic; on the other, those who think it has little to do with the sentence. Most of us would prefer a conception that strikes a balance: logical form that is an objective feature of a sentence and captures its logical character. I will argue that we cannot get what we want. What are these extreme conceptions? In linguistics, logical form is typically con- ceived of as a level of representation where ambiguities have been resolved. According to one highly developed view—Chomsky’s minimalism—logical form is one of the outputs of the derivation of a sentence. The derivation begins with a set of lexical items and after initial mergers it splits into two: on one branch phonological operations are applied without semantic effect; on the other are semantic operations without phono- logical realization. At the end of the first branch is phonological form, the input to the articulatory–perceptual system; and at the end of the second is logical form, the input to the conceptual–intentional system.1 Thus conceived, logical form encompasses all and only information required for interpretation. But semantic and logical information do not fully overlap. The connectives “and” and “but” are surely not synonyms, but the difference in meaning probably does not concern logic. On the other hand, it is of utmost logical importance whether “finitely many” or “equinumerous” are logical constants even though it is hard to see how this information could be essential for their interpretation. -
