Quality Assurance for Clinical Trials
Get PDFCooperative groups, of which the Radiation Therapy Oncology Group (RTOG) is one example, conduct national clinical trials that often involve the use of radiation therapy. In preparation for such a trial, the cooperative group prepares a protocol to define the goals of the trial, the rationale for its design, and the details of the treatment procedure to be followed. The Radiological Physics Center (RPC) is one of several QA offices that is is charged with assuring that participating institutions deliver doses that are clinically consistent and comparable. The RPC does this by conducting a variety of independent audits and credentialing processes. The RPC has compiled data showing that credentialing can help institutions comply with the requirements of a cooperative group clinical protocol. Phantom irradiations have been demonstrated to exercise an institution’s procedures for planning and delivering advanced external beam techniques (Ibbott et al. 2008, Molineu et al. 2005, Molineu et al. 2013). Similarly, RPC data indicate that a rapid review of patient treatment records or planning procedures can improve compliance with clinical trials (Ibbott et al. 2007).The experiences of the RPC are presented as examples of the contributions that a national clinical trials QA center can make to cooperative group trials. These experiences illustrate the critical need for comprehensive QA to assure that clinical trials are successful and cost-effective.The Radiological Physics Center is supported by grants CA 10953 and CA 81647 from the National Cancer Institute, NIH, DHHS

‘Like a Mason Addressing a Block’: Materiality and Design in Geoffrey Hill’s Poetry
No full textThis is the author accepted manuscript. The final version is available from Shearsman Books via the ISBN in this recordNote change of chapter title between accepted and published versionsArguing against the notion that contemporary British poetry is either insular or apolitical, this essay takes a new, interdisciplinary approach to the twenty-first century poetic redeployment of European material culture. It takes as a case study the work of the contemporary British poet, Geoffrey Hill. Hill's poetry makes strategic use of the built environment, in order to negotiate both the European cultural inheritance and to foreground its importance in the British poetic imagination. Reinvesting in built structure on the page, Hill’s inter-artistic eye keeps his audience historically and politically attuned to the uses to which stones, tablets and building blocks are used and re-used across the arts (to attract new audience gazes; to both found and bolster artistic reputations). The powerful contribution of Italian, French and German design models to social, rhetorical and moral thought in British poetry have frequently been neglected in scholarship of contemporary British poetics. This essay offers a corrective, focusing on Hill's distinctive contemporary attention to this shared design politics. Hill's work foregrounds the importance of this European influence, and works consciously to redirect the way that contemporary British audiences understand poetry's complex cultural inheritance and its legacy
Investigation of a possibility of ECG and PPG common measurement
No full textElectrocardiography and Photoplethysmography are basic investigative methods used in healthcare. As the ECG and the PPG are non-invasive methods. The principle consists in ECG recording of electrical activity of the heart and the result of this sensing is a graph plotting—electrocardiogram. PPG is one of the main methods of measurement plethysmography when the result is a graphic record of pulse wave. The main function of PPG is the volumetric flow measurement of blood (e.g. in atherosclerosis, which is possible by vascular permeability derive their rigidity). Both of these methods are used for monitoring of cardiovascular system. It would be advantageous to have possibility to measure ECG and PPG from one place on human body. It would be also advantageous to have only one device and reduce number or size of sensors or electrodes. In this paper we describe developing such system and also investigation the ideal place for placing of sensors for satisfactory measurement
Analysis of kinematic parameters relationships in normal and dysgraphic children
No full textKinematic analysis of handwriting, using digital tablet together with appropriate tests and processing software, allows evaluation of subject graphomotor abilities. Several studies focused on the kinematic parameters extracted from the writing of both normal subjects and subjects with specific disorder, such as dysgraphia, recorded during simple tasks. However, relationships between these parameters have not yet been analyzed. The aim of this study was to examine and identify possible links between kinematic parameters like Amplitude (SA), Duration (SD) and Peak Velocity (PkVS) of Strokes extracted from handwriting and their changes between normal and dysgraphic children. Fifty normal and eighteen dysgraphic children, attending classes from 2nd to 5th grade of primary school, were involved in the study; three cursive tests were administered and analyzed. Results showed a linear relation between SA and PkVS parameters with a similar slope in both groups and reduced peak velocities in some dysgraphic children. A linear relationship was also present between SA and SD parameters in all tests for normal children while an unclear relation was found for dysgraphic children. The latter showed longer durations and slightly lower amplitudes than in normal subjects, in all tasks, as expected in case of poor fluency
Influence of dysgraphia on kinematic characteristics of handwriting in Italian primary school children
No full textHandwriting is a complex skill that improves with
schooling and it is accomplished after the child has
achieved and integrated underlying perceptual-motor
performance components. Even though nowadays children
are expected to acquire a level of handwriting
proficiency, even on the first day of school, at least 27%
of the school population has difficulty with handwriting
and needs to be screened for (with) an intervention
program. In this paper, we examined the influence of
dysgraphia on kinematic characteristics of normal and
dysgraphic Italian children from 2nd to 5th grade of
primary school. Three cursive tasks (sequence of lelele
and Accurate and Fast copy of a sentence) were proposed
and several kinematic parameters were evaluated. Since
differences were present among grades both in normal
and dysgraphic children, each parameter was compared
between children coming from corresponding grades by
means of the Wilcoxon rank sum test. The main results
showed significant differences between the two groups
within each grade for curvilinear velocity, total length and
number of letters per second. Pen-lift durations were
significantly different only in the Accurate and Fast tasks
while number of strokes per second as well as stroke
duration and length showed significant differences
depending on the task and grade. These differences
support the hypothesis of a lower fluency and automation
as well as a different motor planning in dysgraphic
subjects. Finally, many kinematic parameters could be
useful for an early identification of dysgraphia in order to
activate an immediate rehabilitative treatment

Sharing the Desire to Open U.S. Literary Culture to Outside Perspectives : An Interview With Geoffrey Brock, Anna Vilner, and J. Bailey Hutchinson, Editors of The Arkansas International
Get PDFThe Arkansas International is a vibrant space, evident in the recent publications of Anneli Furmark’s comic “Horses” (translated by Hanna Strömberg) and Ladee Hubbard’s essay “Mafolie Hill,” which describes the author\u27s time in the Virgin Islands. The journal, published by students of the University of Arkansas Program in Creative Writing and Translation with Geoffrey Brock as editor-in-chief, seeks to place “US writing in conversation with writing from around the world.” The editors seek more creative nonfiction in translation from underrepresented countries as well as writing in English from underrepresented voices. The enthusiasm of its staff is evident as they describe their process in the following interview conducted via email with Geoffrey Brock, nonfiction editor Anna Vilner, and poetry editor J. Bailey Hutchinson
