Research at the UWC: Understanding the Diversity of Student's Experiences
A pilot study redesigns data collection to reflect increasing diversity in student populations and to improve
writing center consultations and campus outreach efforts.
The Undergraduate Writing Center (UWC) at The University of Texas at Austin (UT) performs roughly 11,500 writing
consultations each year. In addition to providing one-on-one consultations with undergraduate students, a considerable
amount of activity happens behind the scenes. For example, project groups are a mainstay of the UWC and are an
integral aspect of work we do beyond consulting. Up until now, the Research & Publications Project Group has primarily
analyzed data the UWC collects from students’ Intake Forms. The Intake Form asks students to report basic information
regarding their course prefix, their instructor’s information, their assignment, their writing process, and their ESL status.
While these forms lend valuable information about the classes for which students request to receive help and the types of
problems students encounter with their writing, there is a tremendous amount of information we do not collect (and
therefore do not know) about the students who walk through our doors.University Writing Cente

Results of a FRSI material test under Space Shuttle ascent conditions in the Ames Research Center 9x7 foot supersonic wind tunnel (OS13). Space Shuttle aerothermodynamic data report
A test was conducted in the NASA/ARC 9 x 7 foot supersonic wind tunnel to verify the integrity of Felt Reusable Surface Insulation (FRSI) material in a panel flutter environment. A FRSI sample panel was subjected to the shocks, pressure gradients, and turbulence characteristics encountered at dynamic pressure 1.5 times the 3(sigma) dispersed trajectory flight conditions of the Space Shuttle. Static and fluctuating pressure data were obtained for Mach numbers ranging from 1.55 to 2.5 with dynamic pressures of 625 to 1250 psf. The FRSI panel suffered no appreciable damage as a result of the test
microRNAs of parasitic helminths – identification, characterization and potential as drug targets
microRNAs (miRNAs) are small non-coding RNAs involved in post-transcriptional gene regulation. They were first identified in the free-living nematode Caenorhabditis elegans, where the miRNAs lin-4 and let-7 were shown to be essential for regulating correct developmental progression. The sequence of let-7 was subsequently found to be conserved in higher organisms and changes in expression of let-7, as well as other miRNAs, are associated with certain cancers, indicating important regulatory roles. Some miRNAs have been shown to have essential functions, but the roles of many are currently unknown. With the increasing availability of genome sequence data, miRNAs have now been identified from a number of parasitic helminths, by deep sequencing of small RNA libraries and bioinformatic approaches. While some miRNAs are widely conserved in a range of organisms, others are helminth-specific and many are novel to each species. Here we review the potential roles of miRNAs in regulating helminth development, in interacting with the host environment and in development of drug resistance. Use of fluorescently-labeled small RNAs demonstrates uptake by parasites, at least in vitro. Therefore delivery of miRNA inhibitors or mimics has potential to alter miRNA activity, providing a useful tool for probing the roles of miRNAs and suggesting novel routes to therapeutics for parasite control

Moving Walkways, Escalators, and Elevators
We study a simple geometric model of transportation facility that consists of
two points between which the travel speed is high. This elementary definition
can model shuttle services, tunnels, bridges, teleportation devices, escalators
or moving walkways. The travel time between a pair of points is defined as a
time distance, in such a way that a customer uses the transportation facility
only if it is helpful.
We give algorithms for finding the optimal location of such a transportation
facility, where optimality is defined with respect to the maximum travel time
between two points in a given set.Comment: 16 pages. Presented at XII Encuentros de Geometria Computacional,

Detecting all regular polygons in a point set
In this paper, we analyze the time complexity of finding regular polygons in
a set of n points. We combine two different approaches to find regular
polygons, depending on their number of edges. Our result depends on the
parameter alpha, which has been used to bound the maximum number of isosceles
triangles that can be formed by n points. This bound has been expressed as
O(n^{2+2alpha+epsilon}), and the current best value for alpha is ~0.068.
Our algorithm finds polygons with O(n^alpha) edges by sweeping a line through
the set of points, while larger polygons are found by random sampling. We can
find all regular polygons with high probability in O(n^{2+alpha+epsilon})
expected time for every positive epsilon. This compares well to the
O(n^{2+2alpha+epsilon}) deterministic algorithm of Brass.Comment: 11 pages, 4 figure
Arteterapia en el final de la vida
Art therapy allows a particularly valuable biographical creative approach at the end of life. The person concerned has multiple needs - physical, emotional, social and spiritual - that only a holistic attention may claim to embrace, as contemplated in the philosophy of palliative care. The art therapist is integrated into the interdisciplinary team to help to alleviate suffering and accompany the patient and his family. We present here the theoretical foundations and methodology of the intervention as well as the health framework in which it is included.El arteterapia permite una aproximación creativa biográfica particularmente valiosa en la etapa final de la vida.
