Figures of Speech in Galatians

The scope of this thesis will be limited to figures of words or expressions as defined by Terry and Robertson.17 We purposely omit so-called figures of thought (for example, allegory, simile, parallel) since these figures are usually covered adequately in many commentaries and because their inclusion would make this thesis needlessly lengthy

The X-Ray Environment During the Epoch of Terrestrial Planet Formation: Chandra Observations of h Persei

We describe Chandra/ACIS-I observations of the massive ~ 13--14 Myr-old cluster, h Persei, part of the famous Double Cluster (h and chi Persei) in Perseus. Combining the list of Chandra-detected sources with new optical/IR photometry and optical spectroscopy reveals ~ 165 X-ray bright stars with V < 23. Roughly 142 have optical magnitudes and colors consistent with cluster membership. The observed distribution of Lx peaks at Lx ~ 10^30.3 ergs/s and likely traces the bright edge of a far larger population of ~ 0.4--2 Msun X-ray active stars. From a short list of X-ray active stars with IRAC 8 micron excess from warm, terrestrial-zone dust, we derive a maximum X-ray flux incident on forming terrestrial planets. Although there is no correlation between X-ray activity and IRAC excess, the fractional X-ray luminosity correlates with optical colors and spectral type. By comparing the distribution of Lx/L* vs. spectral type and V-I in h Per with results for other 1--100 Myr-old clusters, we show that stars slightly more massive than the Sun (> 1.5 Msun) fall out of X-ray saturation by ~ 10--15 Myr. Changes in stellar structure for > 1.5 Msun stars likely play an important role in this decline of X-ray emission.Comment: 34 pages, 7 Figures, 2 Tables; Accepted for publication in The Astronomical Journa

Teaching functional patterns through robotic applications

We present our approach to teaching functional programming to First Year Computer Science stu- dents at Middlesex University through projects in robotics. A holistic approach is taken to the cur- riculum, emphasising the connections between different subject areas. A key part of the students’ learning is through practical projects that draw upon and integrate the taught material. To support these, we developed the Middlesex Robotic plaTfOrm (MIRTO), an open-source platform built using Raspberry Pi, Arduino, HUB-ee wheels and running Racket (a LISP dialect). In this paper we present the motivations for our choices and explain how a number of concepts of functional programming may be employed when programming robotic applications. We present some students’ work with robotics projects: we consider the use of robotics projects to have been a success, both for their value in reinforcing students’ understanding of programming concepts and for their value in motivating the students

Recovery of a Burkholderia thailandensis-like isolate from an Australian water source

<p>Abstract</p> <p>Background</p> <p><it>Burkholderia thailandensis</it>, a close relative of <it>Burkholderia pseudomallei</it>, has previously been reported only from Southeast Asia and North America. It is biochemically differentiated from <it>B. pseudomallei </it>by the ability to utilize arabinose. During the course of environmental sampling for <it>B. pseudomallei </it>in the Northern Territory of Australia, an isolate, MSMB 43, was recovered that is arabinose positive.</p> <p>Results</p> <p>Genetic analysis using 16S rDNA sequencing and DNA/DNA hybridization indicates that MSMB 43 is most similar to <it>B. thailandensis </it>although multi-locus sequence typing indicates that this isolate is divergent from both <it>B. pseudomallei </it>and other described <it>B. thailandensis</it>.</p> <p>Conclusion</p> <p>We report the isolation and initial characterization of strain MSMB 43, which is a <it>B. thailandensis</it>-like isolate recovered in Australia.</p

Voice and expressivity in free indirect thought representations : imitation and representation

This paper addresses issues in the philosophy of fiction from the perspective of a relevance theoretic approach to communication. Its departure point is the assumption found in both pretence approaches to irony (e.g. Currie 2002, 2006, 2010, Recanati 2000, 2004, 2007, Walton 1990) and Sperber & Wilson’s (1995, 2006, 2011) echoic approach that free indirect discourse and irony should be treated in parallel. Drawing on examples (mainly) from Mansfield’s short stories, It then addresses the question of how we should account for the role of so-called ‘expressives’ in free indirect style and argues that while authors may use them in the imitation of a character’s style or ‘voice’ (especially for the purpose of parody), they may also use them as a means of encouraging readers to construct their own meta-representations of a character’s state of mind. Finally, it addresses the question of what the narrator’s/author’s role is in creating these effects, and argues that the function of a ‘speaking’ narrator must be de-coupled from that of an organizing, selecting narrator (the communicator). Although this distinction can be explained in relevance theoretic terms, it implies that free indirect thought representations must be distinguished from irony and parody, where the relevance of the utterance lies in the audience’s interpretation of the communicator’s thoughts.

The Gray Needle: Large Grains in the HD 15115 Debris Disk from LBT/PISCES/Ks and LBTI/LMIRcam/L' Adaptive Optics Imaging

We present diffraction-limited \ks band and \lprime adaptive optics images of the edge-on debris disk around the nearby F2 star HD 15115, obtained with a single 8.4 m primary mirror at the Large Binocular Telescope. At \ks band the disk is detected at signal-to-noise per resolution element (SNRE) \about 3-8 from \about 1-2\fasec 5 (45-113 AU) on the western side, and from \about 1.2-2\fasec 1 (63-90 AU) on the east. At \lprime the disk is detected at SNRE \about 2.5 from \about 1-1\fasec 45 (45-90 AU) on both sides, implying more symmetric disk structure at 3.8 \microns . At both wavelengths the disk has a bow-like shape and is offset from the star to the north by a few AU. A surface brightness asymmetry exists between the two sides of the disk at \ks band, but not at \lprime . The surface brightness at \ks band declines inside 1\asec (\about 45 AU), which may be indicative of a gap in the disk near 1\asec. The \ks - \lprime disk color, after removal of the stellar color, is mostly grey for both sides of the disk. This suggests that scattered light is coming from large dust grains, with 3-10 \microns -sized grains on the east side and 1-10 \microns dust grains on the west. This may suggest that the west side is composed of smaller dust grains than the east side, which would support the interpretation that the disk is being dynamically affected by interactions with the local interstellar medium.Comment: Apj-accepted March 27 2012; minor correction
