Frege and Davidson on Predication
No full textDavidson's conception of predication is examined and critically discussed with reference to Frege's functional conception of concept and first-and higher order predication. The author argues that Frege's account of predication for all its difficulties, included the ones pointed aout by Davidson, is still the best at our disposal
Pragmatism as Antirepresentationalism?
No full textRichard Rorty's suggestion that American Pragmatism be characterized by its endorsement of an antirepresantationalist conception of the contents of our thoughts is critically discussed with reference to the works of Donald Davidso and Robert Brandom. Rorty's preference goes both to Brandom's Inferentialism and to Davidson's truth-conditional approach to language and interpretation, but these two conceptions are at odds with each other. The author suggests that antirepresentationalism is not incompatible with an allegiance to pragmatism, and that a better conception of the content of our utterances which pays close in attention to context and semantic underdetermination can incorporate representationalist claims without inccurring Rorty's criticisms. The author argues that the clash between Pragmatism and Metaphysical Realism, and that moderate representationalism can go hand in hand with pragmatism
Wittgenstein und Frege über Eigennamen und das Kontextprinzip
No full textThe paper discusses the bearing of Frege's and Wittgenstein's interpretations of the Context Principle on the use of proper names. It is argued that the later Wittgenstein, unlike the author of the Tractatus, has many interesting things to say on the use of proper names that are not at variance with Frege's views. If we bear in mind the paramount importance of context in communication we may come to see Frege's and Wittgenstein's observations on the fluctuating meaning of proper names in a new perspective
On Sense, Tone, and Accompanying Thoughts
No full textThe paper deals with Frege's distinction between sense and colouring or tone as applied both to proper names and to compound sentences. It argues that Frege's way of drawing this distinction is unsatisfactory, much for the same reasons as Grice's theory of conventional implicature is a non starter. The author suggests that tone may contributes to assertoric content depending on contextually specified circumstances. The phenomenon of linguistic underdetermination is very widespread, and tone is only the tip of an iceberg that we need to explore more fully.
The paper deals with Frege's notions of sense and tone within the framework of recent theories of contextualism, literalism and multi-dimensionalism. Dummett's account of Frege's account of sense is reviewed and extended. The author suggests that tone differs from sense only as regards a higher degree of undeterdeterminationa and occasion sensitivity. Tone contributes to assertoric content, and differs from conventional implicatures, as described by Paul Grice and his followers
Compact and tunable focusing device for plasma wakefield acceleration
No full textPlasma wakefield acceleration, either driven by ultra-short laser pulses or electron bunches, represents one of the most promising techniques able to overcome the limits of conventional RF technology and allows the development of compact accelerators. In the particle beam-driven scenario, ultra-short bunches with tiny spot sizes are required to enhance the accelerating gradient and preserve the emittance and energy spread of the accelerated bunch. To achieve such tight transverse beam sizes, a focusing system with short focal length is mandatory. Here we discuss the development of a compact and tunable system consisting of three small-bore permanent-magnet quadrupoles with 520 T/m field gradient. The device has been designed in view of the plasma acceleration experiments planned at the SPARC-LAB test-facility. Being the field gradient fixed, the focusing is adjusted by tuning the relative position of the three magnets with nanometer resolution. Details about its magnetic design, beam-dynamics simulations, and preliminary results are examined in the paper. © 2018 Author(s)
Research Methods: Designing and Conducting Research with a Real-World Focus
No full textThe evolution of the textbook, Research Methods: Designing and Conducting Research with a Real-World Focus, began with the authors’ desire to provide students with the knowledge of scientific methodology and practical tools required to conduct relevant, high-quality research in both academic and professional field settings. Carrie A. Picardi and her co-author, Kevin D. Masick, are organizational psychologists with expertise in both teaching research methods and applying methods to diverse field settings and offer a unique perspective by integrating current research articles with field-specific scenarios. They draw from research methodology tactics, strategy, and constraints from practitioners across the business and social science domains. This textbook is designed to effectively bridge the gap between theory and practice by demonstrating how research is realistically conducted within an organizational setting, and providing readers with relevant, applicable examples from which to learn
Characterization of 27 mev proton beam generated by top-implart linear accelerator
No full textThe first proton linear accelerator for tumor therapy based on an actively scanned beam up to the energy of 150 MeV, is under development and construction by ENEA-Frascati, ISS and IFO, under the Italian TOP-IMPLART project. Protons up to the energy of 7 MeV are generated by a customized commercial injector operating at 425 MHz; currently three accelerating modules allow proton delivery with energy up to 27 MeV. Beam homogeneity and reproducibility were studied using a 2D ionizing chamber, EBT3 films, a silicon diode, MOSFETs, LiF crystals and alanine dosimetry systems. Measurements were taken in air with the detectors at ~1 m from the beam line exit window. The maximum energy impinging on the detectors surface was 24.1 MeV, an energy suitable for radiobiological studies. Results showed beam reproducibility within 5% and homogeneity within 4%, on a circular surface of 16mm in diameter. © The Author(s) 2018

Theft of Employee Services under the United States Penal Code
No full textThis Comment examines the judicial use of 18 U.S.C., Section 641, a penal code section designed to punish theft of money, property, and records of the United States Government, as a means to protect against the theft of employee services. The author argues that general theft statutes, such as section 641, are traditionally tied to legal concepts of property, and that the federal government possesses no property interest in the labor of its employees. The author concludes by recommending that courts strictly construe section 641 and that Congress develop a federal theft of employee services crime
Some Problems of Classification in Linguistics and Biology, 1800–1830
No full textSummary
In this article an attempt is made to bring out the epistemological and methodological affinities between biological and linguistic paradigms of the first decades of the 19th century. After giving an exposition of G. Cuvier’s and E. Geoffroy Saint-Hilaire’s different ways of understanding comparative anatomy, the author calls attention to Kant’s anticipatory discussion of the methodological problems implied by the concept of organism and by teleological reasoning in general. This discussion constitutes the background of Humboldt’s view that a science of language ought not to be based on mechanistic principles but rather stated in terms capable of capturing the ‘rule-governed creativity’ of linguistic activity. The different interpretations the notion of type receives in the works of Cuvier, Geoffroy, Goethe, and Humboldt are discussed, and it is found that the idea of typology as basic for classification was shared by comparativists of both disciplines. Humboldt’s concept of ‘Sprachtypus’ differs in many ways from analogous notions employed by the Schlegel brothers. Further analysis of Humboldt’s idea of ‘Sprachtypus’ and the related concepts of silent and explicit grammar brings out the rationale of the grouping of languages on a teleological basis. This basis is given by the ideal of pure grammatical form which all languages ought to be seen as aiming at, an ideal which forms part of Humboldt’s concept of the ‘perfection’ of language.</jats:p
