Towards the synthesis of a 2-deoxy-2-fluoro-d-mannose building block and characterisation of an unusual 2-S-phenyl anomeric pyridinium triflate salt via 1 → 2 S-migration
Regio- and stereo-selective synthetic routes to 2-deoxy-2-fluoro-d-mannose building blocks are often experimentally challenging when using Selectfluor with the corresponding glycal. We targeted a late-stage method to introduce fluorine in a stereospecific manner using inversion via a triflate. Accordingly, synthesis of a conventionally protected 2-deoxy-2-fluoro-d-mannose β-thioglycoside donor, directly applicable to oligosaccharide synthesis, was attempted using C2-triflate inversion of the corresponding d-glucoside with TBAF. Unexpectedly, an anomeric pyridinium salt was isolated when attempting to form the C2-triflate using Tf2O in pyridine. Indicatively, this proceeds via a 1 → 2 S-migration delivering a 1,2-trans product with α-d-manno configuration and the anomeric pyridinium in a pseudo-equatorial position. The structure of this unexpected intermediate was confirmed in the solid-state using X-ray crystallography. Omission of the pyridine solvent led to dimer formation. Switching the aglycone to an O-para-methoxyphenyl enabled smooth C2 inversion to the desired 2-deoxy-2-fluoro d-mannose system, suitably equipped for further anomeric manipulation
The Social Construction of the Child Sex Offender Explored by Narrative
The notion of "child sex offender" provokes aversion, but it may be that it is a social construction. We suggest that a Dominant narrative, in which child sex offenders are constructed as irredeemable, persists, despite the emergence of assumption challenging Alternative narratives. A story completion method was used to elicit themes of Dominant or Alternative narratives, theory-led thematic analysis was used to identify them. The use and analysis of narrative and free-form stories are well established in social research, but remain a novel concept in the study of offenders. The results support the persistence of the Dominant narrative with two notable exceptions. Conclusions centre on utility of the narrative method to examine offender constructions, and the pervasiveness of Dominant narratives.

Review of \u3ci\u3eReservation Capitalism : Economic Development in Indian Country\u3c/i\u3e by Robert J. Miller
I don\u27t know how many times I\u27ve heard someone say, Capitalism doesn\u27t work in Indian Country ... it\u27s just not compatible with their way of life. While I\u27ve often attempted to counter such misconceptions with my own anecdotal knowledge and experience, Robert J. Miller\u27s excellent Reservation Capitalism thoroughly eviscerates that persistent myth.
The opening chapters offer a comprehensive critique of the antiquated notion of Indians as forest-dwelling socialists, detailing how private property rights, wealth accumulation, and entrepreneurial acumen were commonplace throughout Indian Country prior to European contact. Miller proceeds to recount how reservation economies were devastated by European interactions and how the yoke of the Great White Father\u27s paternalism continues the suppression. He then introduces his core thesis that capitalism and economic activity are consistent with tribal values and culture, although both exogenous and endogenous factors unnecessarily suppress reservation economies. Finally, Miller provides a roadmap for overcoming those deleterious factors and moving Indian Country forward towards self-sustaining reservation economies
GPU-accelerated depth map generation for X-ray simulations of complex CAD geometries
Interactive x-ray simulations of complex computer-aided design (CAD) models can provide valuable insights for better interpretation of the defect signatures such as porosity from x-ray CT images. Generating the depth map along a particular direction for the given CAD geometry is the most compute-intensive step in x-ray simulations. We have developed a GPU-accelerated method for real-time generation of depth maps of complex CAD geometries. We preprocess complex components designed using commercial CAD systems using a custom CAD module and convert them into a fine user-defined surface tessellation. Our CAD module can be used by different simulators as well as handle complex geometries, including those that arise from complex castings and composite structures. We then make use of a parallel algorithm that runs on a graphics processing unit (GPU) to convert the finely-tessellated CAD model to a voxelized representation. The voxelized representation can enable heterogeneous modeling of the volume enclosed by the CAD model by assigning heterogeneous material properties in specific regions. The depth maps are generated from this voxelized representation with the help of a GPU-accelerated ray-casting algorithm. The GPU-accelerated ray-casting method enables interactive (> 60 frames-per-second) generation of the depth maps of complex CAD geometries. This enables arbitrarily rotation and slicing of the CAD model, leading to better interpretation of the x-ray images by the user. In addition, the depth maps can be used to aid directly in CT reconstruction algorithms.This proceeding may be downloaded for personal use only.

Social and Virtual Networks: Evaluating Synchronous Online Interviewing Using Instant Messenger
This paper describes an evaluation of the quality and utility of
synchronous online interviewing for data collection in social network
research. Synchronous online interviews facilitated by Instant Messenger
as the communication medium, were undertaken with ten final year
university students. Quantitative and qualitative content analysis of
respondent and researcher evaluation of the quality and utility of IM
indicated that IM was an integral part of student university life and also
an excellent and innovative communication platform; a potential
advancement for research interviewing. IM was subsequently compared
with face-to-face communication in terms of gains and losses for research
interviewing. The efficacy of the method of online interviewing using IM in
this context is discussed. Key Words: Synchronous Online Interviewing,
Instant Messenger, Social Support Networks, Virtual Networks, and

A comparison of Mulesed and un-Mulesed sheep in the Western District
The Mules operation practically eliminated fly-strike and the need for jetting in a Merino flock, while in "Comeback" sheep flystrike was considerably reduced and jetting requirements were halved. For both types of sheep crutching time and wool soiling were reduced. Although the operation removes a relatively large area of wool-bearing skin, no reduction in wool weight was recorded. It had little or no effect on liveweight, and at lambing there was no increase in the number of difficult births.
