Disagreement and concession in disputes: On the context sensitivity of preference structures
Authors: Kotthoff Helga 
Published: March 2009

ABSTRACTThis article discusses disagreement sequences in German and Anglo-American disputes. It is argued that the context sensitivity of preference for agreement with assessments that Pomerantz 1984 found in her data has to be elaborated and extended. My findings suggest that the preference structure can change once a dissent-turn-sequence has been displayed; in this case, opponents are expected to defend their positions. The reduction of reluctance markers creates a new preference structure which itself has to be accomplished by all participants. Concessions, defined as a participant's agreeing to the central issue after his or her prior disagreement, show reluctance markers which are viewed as indicators of the dispreferred status in other types of talk. Concessions can be distinguished from partially agreeing presequences of dissent turns. Speakers move toward concessions stepwise. Unprepared position shifts can be regarded by the interlocutors as the inability to defend an opinion. Concessions, being an interactional achievement, reframe the dispute.

On puns, comebacks, verbal dueling, and play languages: Speech play in Balinese verbal life
Authors: Sherzer Joel 
Published: March 2009

ABSTRACTIn Bali, speech play is a cultural focus. Several of the many forms of Balinese speech play are investigated – puns, comebacks and verbal dueling, and pig-latin type play languages. These are examined in the context of everyday, informal speech and conversation, verbal routines and events such as storytelling and bargaining, and the artistic and ritual performances for which Bali is famous, such as shadow puppet plays and dance dramas. Attention is paid to the role of multilingualism in Balinese speech play, especially the intersection of the various languages and language levels in constant use in Bali. The significance of speech play in Balinese culture and society is explored. (Ethnography of speaking, speech play, humor, Bali, Indonesia)
The semantics of certainty in Quechua and its implications for a cultural epistemology
Authors: Nuckolls Janis B. 
Published: March 2009

ABSTRACTThis article contributes to attempts on the part of Quechua scholars to understand the evidential system of this language family, and thereby paves the way for a more complex understanding of Quechua speakers' language and culture. The author opposes the position that the most general meaning of the -misuffix is to indicate a direct or first-hand experience; and she holds that specific claims about Quechua speakers' epistemological orientations, based on such an analysis, cannot be supported. Evidence from speakers' use of -miindicates that it encodes two paradigmatic contrasts: one is status-like or modal, the other evidential. The patterning of -mi, including its use and nonuse in a variety of speech types, suggests that Quechua speakers from the Pastaza region of Ecuador do not share Euro-American concern for facts that transcend aesthetic and emotive significance.

Diversity and contestation in linguistic ideologies: German speakers in Hungary
Authors: Gal Susan 
Published: March 2009

ABSTRACTThe classic sociolinguistic opposition between status and solidarity as organizing principles of linguistic variation is currently being integrated with broader social theories of symbolic domination and resistance. However, not enough attention has yet been paid to the multiplicity and fluidity of both dominant and oppositional linguistic ideologies within a single social order. Changing elite conceptions about the links between language and social group vie with each other for supremacy, and are in turn contested by various forms of resistance among linguistic minorities. Debates surrounding the linguistic census in 19th and 20th century Hungary are used here as evidence about diverse dominant ideologies, to show how German-Hungarians have responded by producing multiple, competing, and ambiguous oppositional conceptions and linguistic practices.

Maori and Pakeha English: Some New Zealand social dialect data
Authors: Holmes Janet 
Published: March 2009

ABSTRACTAspects of the extent and nature of the influence of the Maori language on English in New Zealand are explored here within a broad sociolinguistic framework. The current sociolinguistic distribution of Maori and English in New Zealand society is described, and typical users and uses of the variety known as Maori English are identified. Characteristics of Maori English are outlined as background to a detailed examination of the distribution of three phonological features among speakers of Pakeha (European) and Maori background. These features appear to reflect the influence of the Maori language, and could be considered substratum features in a variety serving to signal Maori identity or positive attitudes toward Maori values. Moreover, Maori English may be a source of innovation in the New Zealand English (NZE) of Pakehas, providing features which contribute to the distinctiveness of NZE compared with other international varieties.

Communication of respect in interethnic service encounters
Authors: Bailey Benjamin 
Published: March 2009

ABSTRACTDivergent practices for displaying respect in face-to-face interaction are an ongoing cause of tension in the US between immigrant Korean retailers and their African American customers. Communicative practices in service encounters involving Korean customers contrast sharply with those involving African American customers in 25 liquor store encounters that were videotaped and transcribed for analysis. The relative restraint of immigrant Korean storekeepers in these encounters is perceived by many African Americans as a sign of racism, while the relatively personable involvement of African Americans is perceived by many storekeepers as disrespectful imposition. These contrasting interactional practices reflect differing concepts of the relationship between customer and storekeeper, and different ideas about the speech activities that are appropriate in service encounters.

Shifting contexts: The sociolinguistic significance of nominalization in Japanese television news
Authors: Maynard Senko K. 
Published: March 2009

ABSTRACTThis article examines nominalization in Japanese television news programs with the aim of identifying its sociolinguistic meaning as it relates to context. Given that such programs create shifting contexts available for observation, approximately five hours of news programs (aired in Tokyo in 1992) are examined. The study finds that the use of nominalization varies between two related but different speech contexts identified as “TV Talk” and “TV Announcements.” The significance for the use of nominalization in Japanese is explored, adopting an interdisciplinary approach, by appealing to the critical socio-cultural concepts ofuchi‘inside’ andsoto‘outside’.

“I only listen to one person at a time”: Dissonance and resonance in talk about talk
Authors: Gomes Barbara A. , Martin Laura 
Published: March 2009

ABSTRACTClose examination of a segment of classroom discourse permits definition of a set of linguistic devices and rhetorical structures that characterize the primary speaker's repertoire. As the discourse moves from dialog to monolog, and the teacher's roles and ideological assumptions come into conflict, these discourse patterns are seen to reveal the shifting contexts of talk and social personae that the teacher must use language to reconcile. The analysis claims that, under such conditions of discourse stress, opposing contexts can be temporarily harmonized through discourse structure, even though propositional content is contradictory.

Lexical acculturation, areal diffusion, lingua francas, and bilingualism
Authors: Brown Cecil H. 
Published: March 2009

ABSTRACTThis study continues an investigation of lexical acculturation in Native American languages using a sample of 292 language cases distributed from the Arctic Circle to Tierra del Fuego (Brown 1994). Focus is on the areal diffusion of native language words for imported European Objects and concepts. Approximately 80% of all sharing of such terms is found to occur among closely genetically related languages. Amerindian languages only distantly related, or not related at all, tend to share native labels for acculturated itemsonlywhen these have diffused to them from a lingua franca, such as Chinook Jargon (a pidgin trade language of the Pacific Northwest Coast) or Peruvian Quechua (the language of the Inca empire). Lingua francas also facilitate diffusion of terms through genetically related languages; but sometimes, as in the case of Algonquian languages, these are neither familiar American pidgins nor languages associated with influential nation states. An explanatory framework is constructed around the proposal that degree of bilingualism positively influences extent of lexical borrowing.

When cultural maintenance means linguistic convergence: Pennsylvania German evidence for the Matrix Language Turnover hypothesis
Authors: Fuller Janet M. 
Published: March 2009

ABSTRACTResearch on languages in contact has shown evidence of structural convergence, as well as internally motivated language change; one language which has been frequently studied in this light is Pennsylvania German (PG). Myers-Scotton 1993 posits that convergence involves a change in the selection of the language which sets the morpho-syntactic frame involved in language production. This is called a turnover in the Matrix Language (ML). Data from PG collected in the 1940s, as compared with data collected in the late 1970s and 1980s, indicate that an ML turnover is underway in the sectarian communities; the language can be characterized as having a composite ML. The primary features of convergence in these data are English lexical-conceptual structures in the tense system, English morphological realization patterns in verb phrases, and the increased syntactization of word order in PG. There is only weak evidence for the introduction of English system morphemes at this stage. The loss of case-marking does not conform to English patterns; this indicates that much of the influence of language contact occurs at the lexical-conceptual level.

Being interrupted
Authors: Bilmes Jack 
Published: March 2009

ABSTRACTThe first section of this article argues for an approach to interruption as a participant's, not an analyst's, phenomenon. For analysts, interruption is best treated as a topic, not a resource. The second section examines how participants go about making interruptions OBSERVABLE events in the flow of interaction - in particular, the ways in which they claim violations of speaking rights. The third section considers some of the ways in which such claims are responded to. In the final section, it is suggested that there is a general need for a more systematic approach to the methods through which acts are constituted in terms of the responses they receive.

Catholic and Marxist Paradigms: Ignaz Seipel and Otto Bauer in the First Austrian Republic1
Authors: Alder Douglas 
Published: March 2009

History becomes most fascinating when cosmic ideas clash. The lull between the two world wars in Europe was such a time. Old systems were dying and new ones struggling for birth. Life-and-death contests between cosmologies moved to front stage.Not surprisingly, Vienna continued to be a fulcrum of change then as it was prior to the war as Carl Schorske has depicted it. Here the mass society had emerged during thefin de siécleand here those movements, Catholic and Marxist especially, wrestled for dominance. But the Vienna of the 1920s was no longer the capital of the Habsburg empire of fifty million subjects, rather it was the overlarge head of a truncated remnant counting seven million inhabitants. Nonetheless, it was the scene of the classic post-war ideological drama.
Two Dimensional Analytical Considerations of Large Magnetic and Electric Fields in Laser Produced Plasmas
Authors: Eliezer S. , Loeb A. Loeb 
Published: March 2009

A simple model in two dimensions is developed and solved analytically taking into account the electric and magnetic fields in laser produced plasmas. The electric potential in this model is described by the non-linear differential equationψ = eφ/T, where eφ is the electric potential energy and T is the temperature in energy units. The physical branch ψ < 1, defined by the electron density n = no exp ψ, boundary conditions n (x = 0) = const and n (x = +∞) = 0, introduces a typical electrostatic double layer. The stationary solution of this model is consistent for − 3 ≲ ψ < 1, with electron temperatures in the KeV region and a ratio of the electric (E) to magnetic (B) fields of [E/106 v/cm]/[B/MGauss] ∼ 1.
Dynamics of photon number quantum fluctuations in multiphoton processes
Authors: Zakharov V. I. , Tyuterev Vl. G. 
Published: March 2009

This paper discusses the principles of reduction of quantum noise in optical radiation. The dynamics of photon number fluctuations in direct and cascade two-photon processes is investigated. The paper considers the cases of absorption and emission for the fields originally prepared in coherent and thermal states. It is shown that photon antibunching and bunching should occur for the passed radiation. The photon antibunching effect is only in definite time intervals of field interaction with resonance absorbing or emitting systems.The possible cases of accumulation of photon antibunching effects are considered.
Pulsed ion sources for accelerator inertial fusion
Authors: Humphries S. , Burkhart C. 
Published: March 2009

Experimental results are reported on an extractor for pulsed, high-intensity beams of intermediate mass ions. Aluminum and indium plasmas were generated using a metal vapor vacuum arc. A method for electrostatic separation of ions from electrons at the anode was utilized to generate constant current beams, insensitive to plasma flux variations.A maximum extraction voltage of 30 kV was applied across a 1·6 cm gap. Voltage pulse length ranged from 10 to 50μsec. Peak current densities of 15 mA/cm2 and normalized emittance of εn<3χ10-7; π-m-rad were achieved for Al+ and In+ from a 20-cm2 anode. Ions were predominantly in the +1 ionization state with no observable species contamination. The technology may have application to the induction linac approach to Accelerator Inertial Fusion.
Stopping power for energetic heavy ions in a high temperature material
Authors: Karashima Shosuke , Watanabe Tsutomu 
Published: March 2009

Theoretical treatments of the stopping power are reviewed and problems necessary to extend these treatments to high temperature and high density materials are discussed. Physically important parameters which govern the stopping power properties are indicated. The average equilibrium charge for a gaseous medium is one of the important parameters in the stopping power and the charge-exchange processes involved are discussed. The effective charge is described in terms of a relation between the average equilibrium charge and the effective charge. The atomic energy levels for high density and high temperature matter are also included in the stopping power formula.Actual calculations of the stopping power are made for Pb ions passing through the HIBLIC-target. Range profiles are estimated for Xe and U ions in an ionized Al target for temperatures T = 0 to T = 1290 eV using the Brueckner, Senbetu & Metzler (1982) theory based on a dielectric response function. Results are compared with those of Northcliffe & Schilling (1970), Ziegler (1980), and Hubert et al. (1980). In order to include dynamic local-field corrections in the dielectric function, a model is proposed similar to a two component plasma.

Published: March 2009

The results of high-power ion beam (HPIB) generation and in the magnetically insulated diode (MID) installed on a 3 × 1010-W nanosecond accelerator are given. The possibility of efficient HPIB ballistic focusing with the use of the preformed plasma in the HPIB transport region was demonstrated.Several new diagnostics (spring pendulum and acoustic probe) were used to measure the plasma ablation pressure during the impact of the HPIB with the target.The highest degree of HPIB focusing attained during the experiments with spherical geometries of the diode electrodes was equal to 60. The ablation average pressures measured by the spring pendulum gave several kilobars for 8–10 kA/cm2 of HPIB density. The peak pressure measured by acoustic probes attained tens of kilobars for the same HPIB current amplitudes.
A grain plasma model of galaxies
Authors: Wollmanm E. R. 
Published: March 2009

Electrical quasi-neutrality is not a general property of a thermalized self-gravitating plasma. If the massive component of a two-component plasma consists of charged macroscopic solid grains for which the charge-to-mass ratio is of order then self-gravitation and thermalization lead to substantial large-scale charge separation. An alternative statement of the condition for substantial equilibrium charge separation is that the Jeans length and Debye length of the plasma are similar.We consider a system of condensations in such a plasma and show that properties of the system are similar to observed properties of the system of galaxies.

Published: March 2009

The progress of the experimental research program at GSI for studying beam-plasma interaction phenomena is reported. Heavy-ion beams from the new accelerator facility SIS/ESR at GSI-Darmstadt are now available for experiments, and will soon deliver ≥ 109 particles per pulse in 100 ns. Focused on a small sample of matter, the beams will be able to produce a high-density plasma and to permit investigation of interaction processes of heavy ions with hot ionized matter.For the intense beam from the new heavy-ion synchrotron (SIS), a fine-focus system has been designed to produce a high specific deposition power beam for target experiments with a beam-spot radius of 100 μm. We further discuss improvements of this lens system by nonconventional focusing devices such as plasma lenses.Intense-beam experiments at the RFQ Maxilac accelerator at GSI have already produced the first heavy-ion-induced plasma with a temperature of 0.75 eV. New diagnostic techniques for investigating ion-beam-induced plasmas are presented. The low-intensity beam from the GSI UNILAC has been used to measure energy deposition profiles of heavy ions in hot ionized matter. In this experiment an enhancement of the stopping power for heavy ions was observed. The current experimental research program tests basic plasma theory and addresses key issues of inertial confinement fusion driven by intense heavy-ion beams.
Charge-exchange and energy-loss statistics of swift penetrating ions
Authors: Sigmund P. , Närmann A. 
Published: March 2009

A general and powerful formalism has been developed for computation of energy-loss spectra of penetrating charged particles in the presence of charge exchange. Options on the input side are the cross sections for electron capture and loss, transition rates for radiative and nonradiative spontaneous processes and their associated energy losses or gains, and finally, cross sections for all processes that contribute to particle stopping but are not associated with charge exchange. The formalism generates an n × n transfer matrix, where n is the number of states needed for an adequate description of the projectile under consideration. This matrix delivers the joint distribution of energy loss and exit charge state for a given incident charge state and energy.The formalism can be used in principle as an alternative for Monte Carlo simulation, but until now we have concentrated on direct evaluation of key experimental parameters related to the energy-loss spectrum integrated over all exit charge states, in particular, mean energy loss, straggling, and skewness. Generally, valid analytic expressions have been found for these quantities, each of which can be separated into a stationary term representing chargestate equilibrium and a transient depending on the incident charge state. A brief survey is given of current analytic and numerical efforts addressing other experimental parameters.
Optimum design of gripper jaws for tapered components
Authors: Pham D.T. , Nategh M.J. 
Published: March 2009

SUMMARYFor ease of manufacture, axisymmetric components produced by processes such as forging, casting and moulding are often designed with a taper angle. This paper presents a family of devices for handling such components by their tapered portion. The devices are essentially finger tips, or jaws, to be fitted to standard scissor-type robot grippers. The jaws possess a three-dimensional profile constructed as a stack ofv-shaped planar curves. The special jaw profile enables components of different diameters and taper angles to be gripped concentrically without calling for complex movements to reposition the gripper. The equations describing two categories of profile are derived and the optimum selection of profile parameters to yield compact jaws to grip components of a wide range of dimensions is discussed in the paper.
Towards a theory of sensory robotics
Authors: Pinkava Jan 
Published: March 2009

SUMMARYA partial review of some efforts in robotics research is presented. We identify two broad categories of work: one characterised by application-driven experimental engineering, the other by a more ‘scientific’ approach based on testing theoretical models through implementation. We argue that although the former represents some of the best practical results obtained to-date, this experiment-first-theory-later approach does not contribute to a homogeneous body of knowledge. If robotics is to make measured progress, sound theoretical ground is needed. We argue for a task-specific paradigm for future theoretical work founded on formal models. To this end, we present a general analysis of a sensory robotic system, and identify key elements that must be defined in any formal model before we can decide what sensory information is useful for a given task.
