A rotor-mounted digital instrumentation system for helicopter blade flight research measurements

A rotor mounted flight instrumentation system developed for helicopter rotor blade research is described. The system utilizes high speed digital techniques to acquire research data from miniature pressure transducers on advanced rotor airfoils which are flight tested on an AH-1G helicopter. The system employs microelectronic pulse code modulation (PCM) multiplexer digitizer stations located remotely on the blade and in a hub mounted metal canister. As many as 25 sensors can be remotely digitized by a 2.5 mm thick electronics package mounted on the blade near the tip to reduce blade wiring. The electronics contained in the canister digitizes up to 16 sensors, formats these data with serial PCM data from the remote stations, and transmits the data from the canister which is above the plane of the rotor. Data are transmitted over an RF link to the ground for real time monitoring and to the helicopter fuselage for tape recording. The complete system is powered by batteries located in the canister and requires no slip rings on the rotor shaft

Marginalia and Meaning: Off-Site/Sight/Cite Points of Reference for Extended Trajectories in Learning

This study argues that drawing upon off-site/ sight/ cite points of reference affords a space for extended trajectories of learning and the cultivation of rich and atypical personal meaning unavailable within the terrain and climes of typical schooling frameworks. This paper continues the author\u27s effort to establish the efficacy of a poststructural and poetic aesthetic in qualitative research writing

Exploring Foshay’s Theorem for Curriculum-making in Education: An Elementary School Art Studio Project.

This study explores the question of “why we teach as we do” through the self-reflexive lens described by several noted curriculum theorists, but perhaps best exemplified in a simple theorem for a reflexive curriculum-making praxis first proposed by aesthetics educator Arthur W. Foshay in his aphorism, “Who is to encounter what, why, how, in what circumstances, under what governance, at what cost?” The efficacy in Foshay’s postulation is not self-evident, but must be revealed in an alternating sequence of engagements with the constituent elements of its syntax. The method for this presentation of living inquiry in curriculum-making is trifold, involving the intersection of an art studio project involving 3rd and 4th grade students in a new elementary school; the mixed genre writing of an accompanying paper drawing upon the artist/teacher/researcher’s autobiographical narrative and poetry; and, a series of drawings that retrace and elaborate upon the project and paper. This study argues that Foshay has proposed a qualitative theorem inviting ongoing interpretation in curriculum-making. An alternating sequence of conceptualizing events constitutes a living inquiry, offering the possibility of greater innovation in learning than the more formulaic unit structures designed by mandate

Nutrition in Rehabilitation

Diet has been implicated as a risk factor in atherosclerotic cardiovascular diseases, cancer, diabetes, osteoporosis, obesity, high blood pressure and chronic liver and kidney diseases. These diseases include almost all of the most common non-traumatic causes of death in the United States. It has been suggested that many physicians do not have the opportunity for specific training in nutrition while in medical school. Many studies have shown that patients admitted to a hospital are at risk of malnutrition and that this risk will increase as length of hospital stay increases. Other studies suggested nutritional deficiencies may result in delayed wound healing, major and minor complications, and increased mortality. These complications increase length of stay and hospital costs. A physical therapist, as part of a team, has the chance to impart basic nutritional information to patients. This information may be in addition to information provided to the patient by a physician, nurse, dietician or other health care worker. Patients with improved nutrition benefit from disease prevention through elimination of this risk factor. Patients with improved nutrition also benefit directly from increased energy to participate in physical therapy. This paper will be a review of the literature on the topics of prevalence of malnutrition in hospitals, physician education in nutrition, and nutrition in wound healing to summarize recent findings. From these findings, conclusions concerning nutrition in rehabilitation and recommendations for physical therapists will be provided

One of These Things is Not Like the Other: Art Education and the Symbolic Interaction of Bodies and Self-images.

This article begins with the premise that self-imagery is constituted as a shape-shifting aggregate of symbolic systems that incorporates the human body itself as one of its representations. At intermittent points of the body’s embodiment of visual culture and tacit social experience, alternative representations accrete into varying symbolic systems, the multiple shapes a self-image may take over a lifetime. Given that social identity is derived from the interaction of various symbolic systems, how do some bodies and self-images come to be taken as that of identities incompatible with most others? In this exploration of the self-image and identity, the author reconsiders the purposes of art education in human development, especially when the self-image is given primacy over the objects we typically plan to make in the classroom

Simulation of the Interactions Between Gamma-Rays and Detectors Using BSIMUL

Progress made during 1995 on the Monte-Carlo gamma-ray spectrum simulation program BSIMUL is discussed. Several features have been added, including the ability to model shield that are tapered cylinders. Several simulations were made on the Near Earth Asteroid Rendezvous detector

Essay Review of The Arts and the Creation of Mind by Elliot Eisner

To be so ensconced in addressing the developmental needs of elementary learners through all of the fine arts, whether, as Eisner puts it, “visual, choreographic, musical, literary, or poetic” (p. xii), while at the same time developing content of relevance to the agenda of beginning artist-researchers in our unique era, is also to reflect upon my own journey from elementary artistic understandings to expertise. How did the arts carry me from point A, to point B—from an elementary education during which time art education was effectively cut from New York City public schools because of fiscal crisis, to a postsecondary education that has prepared me to teach to the varying levels of sophistication between grade school and college? The answer that comes to mind is that the practise of the arts has shaped me into a life-long learner, my various experiences in the processes and structures, materials and methods of the arts serving “as models of what educational aspiration and practice might be at its very best” (p. xii)

Visual Culture Archaeology: A Criti/Politi/cal Methodology of Image and Identity

This study argues the efficacy of the phenomenological cultural work of a visual culture archaeology that liberates a political and critical identity, resistant to domination, authoring social change and its own agency through multiple and incommensurable positions. Built upon Foucauldian premises, visual culture archaeology is developed as a methodology for discursive un-naming and re-naming, and emerges from the inherence and attenuation of inscripted meanings in the reinterpretation of identity during a postmodern confluence of ideas and images. The hybridized representation of the African American in Western visual culture has been unique in the effort by some to define us over significant periods as less than human, less than American, or less than statistically significant in the purpose to maintain an unequal relation of economic and political power. This paper continues the author’s effort to establish the efficacy of a poststructural and poetic aesthetic in qualitative research writing

Social and Behavioral Implications of National Collegiate Athletic Association Sickle Cell Trait Screening: The Athletes’ Perspective

Background: In August 2010, the National Collegiate Athletic Association (NCAA) implemented a policy mandating sickle cell trait (SCT) testing for all Division I collegiate athletes. Subsequently, all Division II-III athletes were also compelled to undergo SCT testing. This decision has met with controversy among healthcare providers, researchers, and sickle cell advocates. However, there is little information concerning the athletes’ perspective of this policy. The purpose of this paper is to report the findings of a qualitative study that explored college athletes’ perceptions of sickle cell trait SCT, NCAA policies on SCT testing, and potential implications of SCT screening. Methods: The participants were eighteen male and female athletes (ages 18-24), members of NCAA-governed teams who were on the study campus from April-August 2010. Athletes participated in focus groups that gathered their perceptions of the SCT, the NCAA SCT policy, and social and behavioral implications of a SCT diagnosis. Results: Athletes lacked knowledge of the SCT and the implications of a positive screening test result, desired health education about SCT, were conflicted about sharing health information, and feared loss of playing time if found to carry the SCT. Conclusions: The study revealed athletes’ perceptions of the SCT and mandated NCAA SCT testing that should be addressed by college health professionals
