Pottsian LFG
Potts (2005) provides an elegant and influential approach to the syntax and semantics of a wide range of 'parenthetical' constructions, including various kinds of supplementals/appositives and expressives, which have not received much attention in the LFG literature. The prospect of wholesale importation of Pottsian analyses for such constructions is appealing. However, there are (as Potts himself notes) problems with his approach from a resource sensitive perspective, such as is often assumed in LFG approaches to the syntax semantics interface. Potts sketches, but does not develop, a way of overcoming these problems. In this paper we attempt to develop his proposal and explore ways in which it can be implemented in the architecture of LFG. For exemplification, we focus on supplemental ('appositive', non-restrictive) relative clauses in English. A side effect of our discussion is thus a proposal for an LFG analysis of this construction, which appears to have been neglected hitherto
Resource Splitting and Reintegration with Supplementals
In this paper we survey the various ways of expressing modality in Urdu/Hindi and show that Urdu/Hindi modals provide interesting insights on current discussions of the semantics of modality. There are very few dedicated modals in Urdu/Hindi: most of which has been arrived at constructionally via a combination of a certain kind of verb with a certain kind of embedded verb form and a certain kind of case. Among the range of constructions yielded by such combinations, there is evidence for a two-place modal operator in addition to the one-place operator usually assumed in the literature. We also discuss instances of the Actuality Entailment, which had been shown to be sensitive to aspect, but in Urdu/Hindi appears to be sensitive to aspect only some of the time, depending on the type of modal verb. Indeed, following recent proposals by Ramchand (2011), we end up with a purely lexical account of modality and the Actuality Entailment, rather than the structural one put forward by Hacquard (2010)
Affected experiencers and mixed semantics in LFG/Glue
Bosse, Bruening and Yamada (2012) (BBY) provides a study of several constructions involving ?non-selected? arguments, and outlines an approach to the syntax and semantics of one such construction: the Affected Experiencer (AE) construction. The syntactic analysis relies on abstract functional projections and particular assumptions about configurational syntax. We show how an account may be given without these syntactic assumptions. Semantically, BBY argue that AEs may contribute both at issue content and conventional implicatures, which raises interesting issues for the approach of e.g. Potts (2005). We explore some consequences of their semantic analysis and show that it faces a number of difficulties

K Giants in Baade's Window. II. The Abundance Distribution
This is the second in a series of papers in which we analyze spectra of over
400 K and M giants in Baade's Window, including most of the stars with proper
motions measured by Spaenhauer et al. [AJ, 103, 297 (1992)]. In our first
paper, we measured line--strength indices of Fe, Mg, CN and H and
calibrated them on the system of Faber et al. [ApJS, 57, 711 (1985)]. Here, we
use the index to derive an abundance distribution in
[Fe/H] for 322 stars with effective temperatures between 3900 K and 5160 K.
Our derived values of [Fe/H] agree well with those measured from
high--resolution echelle spectra (e.g., McWilliam \& Rich [ApJS, 91, 749
(1994)]) for the small number of stars in common. We find a mean abundance
for our sample of Baade's Window
K giants. More than half the sample lie in the range \feh\ .
We estimate line--of--sight distances for individual stars in our sample and
confirm that, in Baade's Window, most K giants with are foreground
disk stars, but the great majority (more than 80\%) with belong to the
bulge.
We also compare the metallicities derived from the CN and Mg indices to
those from iron. Most of the metal--rich stars in our sample appear to be
CN--weak, in contrast to the situation in metal--rich globular clusters and
elliptical galaxies. The metal--poor half of our sample ([Fe/H] ) shows
evidence for a mild Mg overenhancement ([Mg/Fe] ); but this is not
seen in the more metal--rich stars ([Fe/H] 0). The K giants in Baade's
Window therefore share some, but not all, of the characteristics of stars in
elliptical galaxies as inferred from their integrated light.Comment: Accepted for publication in the Astronomical Journal, tentatively

A deep survey of the low-surface-brightness radio sky
We have made a radio survey--the Australia Telescope Low Brightness Survey
(ATLBS)--of 8.4 square degrees sky area, using the Australia Telescope Compact
Array in the 20-cm band, in an observing mode designed to provide wide-field
images with exceptional sensitivity in surface brightness, and thereby explore
a new parameter space in radio source populations. The goals of this survey are
to quantify the distribution in angular sizes, particularly at weak surface
brightness levels: this has implications for the confusion in deep surveys with
the SKA. The survey is expected to lead to a census of the radio emission
associated with low-power radio galaxies at redshifts 1-3, without any missing
extended emission, and hence a study of the cosmic evolution of low-power radio
galaxies to higher redshift and a comprehensive study of the AGN feedback
during the intense black hole growth phase during this redshift range.Comment: 5 pages, includes 2 figures and 1 table. To appear in the proceedings
of "From Planets to Dark energy: the modern radio universe" in the online

ATLBS: the Australia Telescope Low-brightness Survey
We present a radio survey carried out with the Australia Telescope Compact
Array. A motivation for the survey was to make a complete inventory of the
diffuse emission components as a step towards a study of the cosmic evolution
in radio source structure and the contribution from radio-mode feedback on
galaxy evolution. The Australia Telescope low-brightness survey (ATLBS) at 1388
MHz covers 8.42 sq deg of the sky in an observing mode designed to yield images
with exceptional surface brightness sensitivity and low confusion. The ATLBS
radio images, made with 0.08 mJy/beam rms noise and 50" beam, detect a total of
1094 sources with peak flux exceeding 0.4 mJy/beam. The ATLBS source counts
were corrected for blending, noise bias, resolution, and primary beam
attenuation; the normalized differential source counts are consistent with no
upturn down to 0.6 mJy. The percentage integrated polarization Pi_0 was
computed after corrections for the polarization bias in integrated polarized
intensity; Pi_0 shows an increasing trend with decreasing flux density.
Simultaneous visibility measurements made with longer baselines yielded images,
with 5" beam, of compact components in sources detected in the survey. The
observations provide a measurement of the complexity and diffuse emission
associated with mJy and sub-mJy radio sources. 10% of the ATLBS sources have
more than half of their flux density in extended emission and the fractional
flux in diffuse components does not appear to vary with flux density, although
the percentage of sources that have complex structure increases with flux
density. The observations are consistent with a transition in the nature of
extended radio sources from FR-II radio source morphology, which dominates the
mJy population, to FR-I structure at sub-mJy flux density. (Abridged)Comment: 18 pages, 8 figues, 6 tables, accepted for publication in MNRA
Students\u27 Perception of Involvement In Transition
The purpose of this study was to investigate the exceptional student\u27s perception of his or her involvement in the transition process as well as expectations and desired outcomes for adult life. A sample of twenty-one students classified as learning disabled who were taking a study skills class chose to participate in this study. The results show that over half of this sample were not aware that they were currently in a program designed to assist them with planning their future. Even so, over ninety percent stated that they had a future plan in mind, with over ninety percent planning to continue their education. These findings show that the population surveyed has a positive outlook for the future
