Pragmatic uses of demonstratives in Cirebon Javanese conversation

This study examines demonstratives in the variety of Javanese spoken in the region of Cirebon, on the north coast of the province of West Java. After introducing the demonstrative paradigms found in Cirebon Javanese, this study analyses their functional distribution in conversational discourse based on the taxonomy of demonstrative functions presented in Diessel (1999). The use of demonstratives with reference to first and second person and the role of demonstratives in conversational interaction is also discussed. Cirebon Javanese has a three-way demonstrative system with a number of variant forms. The medial forms are by far the most frequently occurring demonstratives in the conversational data. The anaphoric function is by far the most common function. The use of demonstratives with personal deictic forms and the importance of demonstratives in managing talk in interaction suggest avenues for further research

Love is . . . an abstract word: the influence of phonological and semantic factors on verbal short-term memory in Williams syndrome

It has been claimed that verbal short-term memory in Williams syndrome is characterised by an over-use of phonological coding alongside a reduced contribution of lexical semantics. We critically examine this hypothesis and present results from a memory span task comparing performance on concrete and abstract words, together with a replication of a span task using phonologically similar and phonologically dissimilar words. Fourteen participants with Williams syndrome were individually matched to two groups of typically developing children. The first control group was matched on digit span and the second on vocabulary level. Significant effects were found for both the semantic and the phonological variables in the WS group as well as in the control groups, with no interaction between experimental variable and group in either experiment. The results demonstrate that, despite claims to the contrary, children and adults with WS are able to access and make use of lexical semantics in a verbal short-term memory task in a manner comparable to typically developing individuals

B spectroscopy using all-to-all propagators

We measure the ground and excited states for B mesons in the static limit using maximally variance reduced estimators for light quark propagators. Because of the large number of propagators we are able to measure accurately also orbitally excited P, D and F states. We also present some results for Lambda_b.Comment: 3 pages, 3 figures.

What Does That Have To Do With the Flow of Ideas? Relevance in indonesian and American Interaction

The study of communicative style is important for understanding difficulties that arise in cross-cultural communication, but has been little researched in Indonesia, an area with a long history of cross-cultural interaction. This thesis looks at one aspect of communicative style, the maintenance of relevance, in groups of Indonesians and Americans involved in discussing an issue of professional concern through the medium of English. Relevance is analyzed in terms of the topic frameworks which the participants use for establishing the relevance of contributions made in the discussions. It is found that the American participants actively create relevance in the discussions, while the Indonesians participants assume the relevance of contributions to the discussions. Implications for the field of discourse analysis and for cross-cultural communication are discussed

An Evolving Understanding of Enigmatic Large Ripples on Mars

Two scales of ripples form in fine sand on Mars. The larger ripples were proposed to have an equilibrium size set by an aerodynamic process, making them larger under thinner atmospheres and distinct from smaller impact ripples. Sullivan et al. (2020) show that large ripples can develop in a numerical model due to Mars’ low atmospheric pressure. Although their proposed growth‐limiting mechanism is consistent with an aerodynamic process, they argue that the ripples in their model are simply large versions of impact ripples, not a separate class of ripples. Here, we explore this debate by synthesizing recent advances in large‐ripple formation. Although significant knowledge gaps remain, it is clear that large martian ripples are larger under thinner atmospheres, and thus remain a powerful paleoclimate indicator

Assessing the Accuracy of Complex Refractive Index Retrievals from Single Aerosol Particle Cavity Ring-Down Spectroscopy

<p>Cavity ring-down spectroscopy (CRDS) of single, optically manipulated aerosol particles affords quantitative retrieval of refractive indices for particles of fixed or evolving composition with high precision. Here, we quantify the accuracy with which refractive index determinations can be made by CRDS for single particles confined within the core of a Bessel laser beam and how that accuracy is degraded as the particle size is progressively reduced from the coarse mode (>1 μm radius) to the accumulation mode (<500 nm radius) regime. We apply generalized Lorenz–Mie theory to the intra-cavity standing wave to explore the effect of particle absorption on the distribution of extinction cross section determinations resulting from stochastic particle motion in the Bessel beam trap. The analysis provides an assessment of the accuracy with which the real, <i>n</i>, and imaginary, κ, components of the refractive index can be determined for a single aerosol particle.</p> <p>Published with license by American Association for Aerosol Research</p> <p><a href="https://www.tandfonline.com/pb-assets/tandf/Migrated/UAST_VideoAbstract_Transcript.pdf" target="_blank">Read the transcript</a></p> <p><a href="https://vimeo.com/263371383" target="_blank">Watch the video on Vimeo</a></p

Maximal variance reduction for stochastic propagators with applications to the static quark spectrum

We study a new method -- maximal variance reduction -- for reducing the variance of stochastic estimators for quark propagators. We find that while this method is comparable to usual iterative inversion for light-light mesons, a considerable improvement is achieved for systems containing at least one infinitely heavy quark. Such systems are needed for heavy quark effective theory. As an illustration of the effectiveness of the method we present results for the masses of the ground state and excited states of $\bar{Q}q$ mesons and $\bar{Q}qq$ baryons. We compare these results with the experimental spectra involving $b$ quarks.Comment: 31 pages with 7 postscript file
