Conscientious Design: Design Proposals for Accomodating Multiple Sclerosis Patients

This evidence-based research explains and provides interior design strategies for redesign and future design to meet the needs of MS patients. The project entails an analysis of MS patient needs, an assessment of interior design implementations in similar medical fields (with patients who have similar symptoms to those with MS), and the creation of information materials containing recommended design practices for distribution. The materials will include details on lay-outs, upholstery, space planning, suggested equipment, color schemes, and recommended practices to be applied to current or future facilities that treat MS patients. These materials provide previously unexplored and much needed research and applications for use in the field of interior design

Neutron Scattering Study of Crystal Field Energy Levels and Field Dependence of the Magnetic Order in Superconducting HoNi2B2C

Elastic and inelastic neutron scattering measurements have been carried out to investigate the magnetic properties of superconducting (Tc~8K) HoNi2B2C. The inelastic measurements reveal that the lowest two crystal field transitions out of the ground state occurat 11.28(3) and 16.00(2) meV, while the transition of 4.70(9) meV between these two levels is observed at elevated temperatures. The temperature dependence of the intensities of these transitions is consistent with both the ground state and these higher levels being magnetic doublets. The system becomes magnetically long range ordered below 8K, and since this ordering energy kTN ~ 0.69meV << 11.28meV the magnetic properties in the ordered phase are dominated by the ground-state spin dynamics only. The low temperature structure, which coexists with superconductivity, consists of ferromagnetic sheets of Ho{3+ moments in the a-b plane, with the sheets coupled antiferromagnetically along the c-axis. The magnetic state that initially forms on cooling, however, is dominated by an incommensurate spiral antiferromagnetic state along the c-axis, with wave vector qc ~0.054 A-1, in which these ferromagnetic sheets are canted from their low temperature antiparallel configuration by ~17 deg. The intensity for this spiral state reaches a maximum near the reentrant superconducting transition at ~5K; the spiral state then collapses at lower temperature in favor of the commensurate antiferromagnetic state. We have investigated the field dependence of the magnetic order at and above this reentrant superconducting transition. Initially the field rotates the powder particles to align the a-b plane along the field direction, demonstrating that the moments strongly prefer to lie within this plane due to the crystal field anisotropy.

Paraprofessional involvement in self-determination instruction for students with high-incidence disabilities

This is the publisher's version, also found here: http://cec.metapress.com/content/lq6v516h2rn178ut/?p=f618223ce7404c508a820fb0873297e2&pi=5Although enhancing students' self-determination is advocated as a central element of high-quality special education and transition services, little is known about the ways in which paraprofessional are involved in promoting self-determination or the extent to which they share teachers' views regarding its importance. The authors surveyed 223 paraprofessional from 115 randomly selected public school to examine their perspectives on promoting self-determination among students with high-incidence disabilities. Overall, paraprofessional attributed high ievel of importance to each of the 7 component elements of self-determination (i.e., choice making, decision making, problem solving, goal setting and attainment, self-advocacy and leadership, self-management and self-regulation, and self-awareness and self-knowledge). The extent to which paraprofessional reported providing instruction addressing each of the 7 components of self determination was moderate, with average ratings all slightly above the midpoint of the scale. This article presents implications for the involvement of paraprofessional in supporting the development of self-determination among students with high-incidence disabilities, along with recommendations for future research

Probing Supraglacial Debris on Mars 1: Sources, Thickness, and Stratigraphy

Geomorphic and geophysical evidence supports a debris-covered glacier origin for a suite of landforms at themid-latitudes of Mars, including lobate debris aprons (LDA), lineated valley fill (LVF), and concentric crater fill (CCF). These large reservoirs of ice and their near-surface structure provide a rich record for understanding the planet's climate and history of global volatile exchange over the past billion years. LDA, LVF, and CCF are also potential sites for future robotic and human missions but the accessibility of glacial ice for direct sampling and in situ resource utilization depends largely on the geotechnical properties of the surface debris ("supraglacial debris"), including its thickness, grain sizes, and density structure. The physical properties of this supraglacial debris layer have been poorly constrained. We use images of morphology, digital elevation models, thermal inertia data, and radar sounding data to probe the near surface of LDA, LVF, and CCF in Deuteronilus Mensae in order to place constraints on the sources, grain sizes, thickness, and stratigraphy of supraglacial debris. We find evidence for at least a two-layer stratigraphy. Layered mantle consisting of atmospherically emplaced dust and ice superposes boulder-rich sediment sourced by rockfalls glacially transported downslope. High thermal inertia, boulder-rich termini and debris bands reminiscent of medial moraines are found throughout the study region, supporting a rockfall origin for at least a fraction of the debris exposed at the surface. This supraglacial debris layer would have thickened with time from sublimation of glacial ice and liberation of englacial sediment and dust. At present, the entire supraglacial debris package is a minimum of a few meters in thickness and is likely tens of meters in thickness in many locations, possibly thinning regionally at lower latitudes and locally thinning toward the headwalls. The lack of terracing or interior structures in craters formed within LDA, LVF, and CCF and the absence of near-surface reflectors in SHARAD radar data further suggest that no strong contrasts i

Comparing Volcanic Terrains on Venus and Earth: How Prevalent are Pyroclastic Deposits on Venus?

In the last several years, astronomers have discovered several exoplanets with masses less than 10 times that of the Earth [1]. Despite the likely abundance of Earth-sized planets, little is known about the pathways through which these planets evolve to become habitable or uninhabitable. Venus and Earth have similar planetary radii and solar orbital distance, and therefore offer a chance to study in detail the divergent evolution of two objects that now have radically different climates. Understanding the extent, duration, and types of volcanism present on Venus is an important step towards understanding how volatiles released from the interior of Venus have influenced the development of the atmosphere. Placing constraints on the extent of explosive volcanism on Venus can provide boundary conditions for timing, volumes, and altitudes for atmospheric injection of volatiles. In addition, atmospheric properties such as near-surface temperature and density affect how interior heat and volatiles are released. Radar image data for Venus can be used to determine the physical properties of volcanic deposits, and in particular, they can be used to search for evidence of pyroclastic deposits that may result from explosive outgassing of volatiles. For explosive volcanism to occur with the current high atmospheric pressure, magma volatile contents must be higher than is typical on Earth (at least 2-4% by weight) [2,3]. In, addition, pyroclastic flows should be more prevalent on Venus than convective plumes and material may not travel as far from the vent source as it would on Earth [3]. Areas of high radar backscatter with wispy margins that occur near concentric fractures on Sapho Patera [4] and several coronae in Eastern Eistla Regio [5] have been attributed to collapse of eruption columns and runout of rough materials

Geologic Studies of Planetary Surfaces Using Radar Polarimetric Imaging

Radar is a useful remote sensing tool for studying planetary geology because it is sensitive to the composition, structure, and roughness of the surface and can penetrate some materials to reveal buried terrain. The Arecibo Observatory radar system transmits a single sense of circular polarization, and both senses of circular polarization are received, which allows for the construction of the Stokes polarization vector. From the Stokes vector, daughter products such as the circular polarization ratio, the degree of linear polarization, and linear polarization angle are obtained. Recent polarimetric imaging using Arecibo has included Venus and the Moon. These observations can be compared to radar data for terrestrial surfaces to better understand surface physical properties and regional geologic evolution. For example, polarimetric radar studies of volcanic settings on Venus, the Moon and Earth display some similarities, but also illustrate a variety of different emplacement and erosion mechanisms. Polarimetric radar data provides important information about surface properties beyond what can be obtained from single-polarization radar. Future observations using polarimetric synthetic aperture radar will provide information on roughness, composition and stratigraphy that will support a broader interpretation of surface evolution

Communalism in Egyptian politics: The experience of the Copts, 1918-1952.

This thesis explores a particular experiment in political accommodation between the Muslim majority and Coptic minority in Egypt between 1918 and 1952. The Egyptians then seized the opportunity presented by a changing political system to restructure the governing arrangements between Muslims and Copts and involve the latter more fully in the political process. Many hoped to see the collaboration of the 1919 revolution spur the creation of both a new collective Egyptian identity and a state without religious bias. Traditional ways of governing, however, were not so easily cast aside, and Islam continued to have a political role. Some Egyptians held tenaciously to the traditional arrangements which had both guaranteed Muslim primacy and served relatively well to protect the Copts and afford them some autonomy. Differences within the Coptic community over the wisdom of trusting the genuineness and durability of Muslim support for equality were accented by a protracted struggle between reforming laymen and conservative clergy for control of the community. The unwillingness of all parties to compromise hampered the ability of the community both to determine and defend its interests. The Copts met with modest success in their attempt to become full Egyptian citizens. As one example, their influence in the Wafd, the preeminent political party, was very strong prior to and in the early years of the Constitutional Monarchy. As a second, their formal representation was generally adequate and, in some Parliaments, better than adequate. However, this very success produced a backlash which caused many Copts to believe, by the 1940s, that the experiment had failed: political activity had become fraught with risk for them. Coptic complaints about Muslim intolerance abounded and reflected the broad criticisms levelled at minority behaviour by Muslims. At the close of the monarchy, equality and shared power seemed notions as distant as in the disheartening years before the revolution

Syk and Zap-70 function redundantly to promote angioblast migration

AbstractSpleen tyrosine kinase (Syk) plays critical roles in B-cell and T-cell development, the maintenance of vascular integrity, and proper partitioning of the blood vascular and lymphatic vascular system. Here, we utilize the zebrafish as an in vivo system to demonstrate novel roles for Syk and the related kinase Zeta associated protein (Zap-70) in promoting angioblast migration. Partial knockdown of either gene results in early angiogenic delay of the intersegmental vessels, dorsal intersegmental vessel patterning defects, and partial loss of the thoracic duct. Higher dose knockdown of both genes results in little to no angiogenic sprouting of the intersegmental vessels, a phenotype which resembles knockdown of vegfa. Di-phosphorylated ERK, an effector of the vegfa pathway, is also downregulated in the aorta of syk:zap double morphants. Over-expression of syk under the control of a blood-specific or vascular-specific promoter rescues sprouting defects after loss of vegfa. Together these results suggest that syk and zap-70 function redundantly in an early progenitor to promote the migration of intersegmental vessel angioblasts and lymphangioblasts that contribute to the thoracic duct, either downstream of, or in parallel to vegfa
