TL;DR: Key program components, including blended instruction, extensive field-based assessments with supervision, learning community supports, and content training, are described along with implementation challenges and training outcomes.
Abstract: The shortage of highly qualified special educators is most pronounced in rural schools serving populations characterized by poverty, low achievement, disability, and cultural diversity. The result ...

TL;DR: A greater role is revealed of the left PPC than the right in the use of local sensory cues for spatial navigation, and the results show that the PPC is not the repository of the “engram” for this learned visuospatial behavior.
Abstract: Rats with sham, unilateral, or bilateral aspiration lesions of the posterior parietal cortex (PPC) were trained in a water T-maze to use flashing lights located along the starting alley (two each) and inner walls of the goal alleys (two each) to find a hidden escape platform. Thereafter, the performance of the spatial response was tested under several conditions. Rats with bilateral PPC lesions were significantly inferior to unilateral- and sham-injured rats in learning the “turn-signal” cued spatial task. Also, left-PPC-injured rats committed significantly more errors than did the control animals. After mastering the task, cue saliency was reduced and the amount of spatial discontiguity between the stimuli and escape site was increased in two stages. That is, the flashing light closest to the escape platform was turned off for one testing session. On the following day, animals were required to rely on information located within the starting alley to make the correct spatial response at the choice point. Animals with bilateral or left PPC lesions were significantly impaired on the task with cues located only in the starting alley. The animals were then tested with competing constant illumination of the lights on the side of the apparatus opposite the flashing-light cues. The performance of all animals dropped to chance and failed to improve with training. Finally, three of the sham-operated controls were retrained to criterion on the original discrimination and prepared with bilateral PPC injuries. Substantial savings was observed. The results reveal a greater role of the left PPC than the right in the use of local sensory cues for spatial navigation, and they show that the PPC is not the repository of the “engram” for this learned visuospatial behavior.

TL;DR: Results show that algorithm 3 generates better interpolated objects than the segmented volumes arising from standard grayscale-based interpolation techniques in cases where the objects to interpolate are thin tube-like structures, such as the coronary arteries.
Abstract: The problem of interpolating a high-resolution binary-valued 3-D image given a lower-resolution grayscale 3-D image and a corresponding segmented 3-D image is addressed. Three algorithms for this problem are described. Algorithms 1 and 2 perform shape- and located-based binary interpolation. Algorithm 3, which subsumes algorithms 1 and 2, incorporates grayscale information as well as object shape and slice-to-slice object spatial relationships. Results show that algorithm 3 generates better interpolated objects than the segmented volumes arising from standard grayscale-based interpolation techniques. Algorithm 2, which subsumes algorithm 1, uses only the known presegmented volume to interpolate a new binary-valued volume. the methods show particular merit in cases where the objects to interpolate are thin tube-like structures, such as the coronary arteries. >

Abstract: There are 39 recorded prehistoric archeological sites located on San Salvador Island, Bahamas. These prehistoric sites are settlements of the indigenous inhabitants of the island, the Lucayans. Data exist for both the archaeological sites and their surrounding resources, including site location, vegetation, geology, and proximity to fresh water, coastline, wetlands, and reefs, etc. Specific application of Geographic Information Systems (GIS) to Lucayan settlements on San Salvador had not been performed in a major way prior to the present research, although it was proposed by other researchers. GIS data analysis required the application of a computer program, ArcGIS 9.2. In ArcGIS, the prehistoric settlement pattern of San Salvador was investigated via rapid extraction of data critical to perform analyses of resources surrounding the archaeological sites. Resulting information, displayed in various forms, primarily maps and data tables, helped to identify past cultural patterns, trends in prehisto...

TL;DR: The presence of N. carlquistii in the Republic flora demonstrates that Nuphar section Astylus had established its present-day structure, plant habit, mode of seed dispersal, and aquatic niche by the early Eocene in the Okanogan Highlands of northwestern North America.
Abstract: Premise of research. Fossil remains of a water lily, Nuphar carlquistii DeVore, Taylor & Pigg sp. nov. (Nymphaeaceae), are described from the latest early Eocene Republic flora of north-central Washington. Specimens include several fruits, one with in situ seeds, others with remnants of stamens and stamen attachment scars, and dispersed seeds found both within a mucilaginous dispersal matrix and separately. Associated structures, including a stigmatic disk, isolated tepals, and several rhizome segments bearing nested clusters of roots and leaf scars, are included in N. cf. carlquistii.Methodology. Fossils preserved in a lacustrine shale were degaged to reveal details, photographed with LM, and compared morphologically with extant material of related plants.Pivotal results. The study documents the most complete fossil Nuphar known to date. The combination of multiple organs, including fruits, seeds, stamens, and rhizomes with leaf scars and clustered root scars, demonstrates that Eocene Nuphar had vegetati...
