Fred Kabotie, Elizabeth Willis DeHuff, and the Genesis of the Santa Fe Style
Those scholars who have overlooked the relevance of Fred Kabotie and the Santa Fe Style he developed have missed an important historical segment of early Native American painting. This dissertation underscores the convergence of diverse intellectual, artistic and cultural backgrounds, especially those of Kabotie and Elizabeth Willis DeHuff, his first art teacher, which led to the formation of the Santa Fe Style in 1918. This style was formative for Dorothy Dunnās later Studio School at the Santa Fe Indian Boarding School.
This first generation of the Santa Fe Style of watercolor painting was empowered by highly educated men and women, who helped to ensure the national recognition Kabotieās work received. Among Kabotieās early supporters were Elizabeth Willis and John DeHuff, Mabel Dodge Luhan, Edgar Lee Hewett, Kenneth Chapman, Robert Henri, Maynard Dixon, Marsden Hartley, John Sloan, John Louw Nelson and George Gustav Heye. By uncovering the multiple discourses connecting these individuals with Kabotie and his work, this study develops a basis for analyzing the many perspectives this new style synthesized and advanced. This dissertation positions Kabotie and the Santa Fe Style within these and several larger cultural arenas, including Hopi culture, modern art and Santa Fe intellectuals, thus providing a multistoried dimensionality overlooked in earlier scholarship.
Through evaluating these individuals who informed and empowered the creation of the Santa Fe Style, while carefully considering Kabotieās response to them in his work, this dissertation initiates a clearer understanding of early twentieth-century cultural and artistic interactions, both locally and nationally. The Santa Fe Style provided a new direction for American Indian art prior to World War II; it initiated a fresh dialogue between the Hopi people and the Anglo government, and it afforded a complex and ongoing conversation for not just Fred Kabotie and his art, but also, through him, the Hopi people. Moreover, it had a profound effect on the development of Southwest Native American painting over the next fifty years
Cheryl's Birthday
We present four logic puzzles and after that their solutions. Joseph Yeo
designed 'Cheryl's Birthday'. Mike Hartley came up with a novel solution for
'One Hundred Prisoners and a Light Bulb'. Jonathan Welton designed 'A Blind
Guess' and 'Abby's Birthday'. Hans van Ditmarsch and Barteld Kooi authored the
puzzlebook 'One Hundred Prisoners and a Light Bulb' that contains other
knowledge puzzles, and that can also be found on the webpage

Current and future nonstimulants in the treatment of pediatric ADHD: Monoamine reuptake inhibitors, receptor modulators, and multimodal agents
Attention-deficit/hyperactivity disorder (ADHD), the single most common neuropsychiatric disorder with cognitive and behavioral manifestations, often starts in childhood and usually persists into adolescence and adulthood. Rarely seen alone, ADHD is most commonly complicated by other neuropsychiatric disorders that must be factored into any intervention plan to optimally address ADHD symptoms. With more than 30 classical Schedule II (CII) stimulant preparations available for ADHD treatment, only three nonstimulants (atomoxetine and extended-release formulations of clonidine and guanfacine) have been approved by the United States Food and Drug Administration (FDA), all of which focus on modulating the noradrenergic system. Given the heterogeneity and complex nature of ADHD in most patients, research efforts are identifying nonstimulants which modulate pathways beyond the noradrenergic system. New ADHD medications in clinical development include monoamine reuptake inhibitors, monoamine receptor modulators, and multimodal agents that combine receptor agonist/antagonist activity (receptor modulation) and monoamine transporter inhibition. Each of these pipeline ADHD medications has a unique chemical structure and differs in its pharmacologic profile in terms of molecular targets and mechanisms. The clinical role for each of these agents will need to be explored with regard to their potential to address the heterogeneity of individuals struggling with ADHD and ADHD-associated comorbidities. This review profiles alternatives to Schedule II (CII) stimulants that are in clinical stages of development (Phase 2 or 3). Particular attention is given to viloxazine extended-release, which has completed Phase 3 studies in children and adolescents with ADHD
Beyond megadrought and collapse in the Northern Levant: The chronology of Tell Tayinat and two historical inflection episodes, around 4.2ka BP, and following 3.2ka BP
There has been considerable focus on the main, expansionary, and inter-regionally linked or āglobalisingā periods in Old World pre- and proto-history, with a focus on identifying, analyzing and dating collapse at the close of these pivotal periods. The end of the Early Bronze Age in the late third millennium BCE and a subsequent āintermediateā or transitional period before the Middle Bronze Age (~2200ā1900 BCE), and the end of the Late Bronze Age in the late second millennium BCE and the ensuing period of transformation during the Early Iron Age (~1200ā900 BCE), are key examples. Among other issues, climate change is regularly invoked as a cause or factor in both cases. Recent considerations of ācollapseā have emphasized the unpredictability and variability of responses during such periods of reorganization and transformation. Yet, a gap in scholarly attention remains in documenting the responses observed at important sites during these ātransformativeā periods in the Old World region. Tell Tayinat in southeastern Turkey, as a major archaeological site occupied during these two major āin betweenā periods of transformation, offers a unique case for comparing and contrasting differing responses to change. To enable scholarly assessment of associations between the local trajectory of the site and broader regional narratives, an essential preliminary need is a secure, resolved timeframe for the site. Here we report a large set of radiocarbon data and incorporate the stratigraphic sequence using Bayesian chronological modelling to create a refined timeframe for Tell Tayinat and a secure basis for analysis of the site with respect to its broader regional context and climate history
Probabilistic Models for Solar Particle Events
Probabilistic Models of Solar Particle Events (SPEs) are used in space mission design studies to provide a description of the worst-case radiation environment that the mission must be designed to tolerate.The models determine the worst-case environment using a description of the mission and a user-specified confidence level that the provided environment will not be exceeded. This poster will focus on completing the existing suite of models by developing models for peak flux and event-integrated fluence elemental spectra for the Z>2 elements. It will also discuss methods to take into account uncertainties in the data base and the uncertainties resulting from the limited number of solar particle events in the database. These new probabilistic models are based on an extensive survey of SPE measurements of peak and event-integrated elemental differential energy spectra. Attempts are made to fit the measured spectra with eight different published models. The model giving the best fit to each spectrum is chosen and used to represent that spectrum for any energy in the energy range covered by the measurements. The set of all such spectral representations for each element is then used to determine the worst case spectrum as a function of confidence level. The spectral representation that best fits these worst case spectra is found and its dependence on confidence level is parameterized. This procedure creates probabilistic models for the peak and event-integrated spectra
Cloud Optical Depth Retrievals from Solar Background "signal" of Micropulse Lidars
Pulsed lidars are commonly used to retrieve vertical distributions of cloud and aerosol layers. It is widely believed that lidar cloud retrievals (other than cloud base altitude) are limited to optically thin clouds. Here we demonstrate that lidars can retrieve optical depths of thick clouds using solar background light as a signal, rather than (as now) merely a noise to be subtracted. Validations against other instruments show that retrieved cloud optical depths agree within 10-15% for overcast stratus and broken clouds. In fact, for broken cloud situations one can retrieve not only the aerosol properties in clear-sky periods using lidar signals, but also the optical depth of thick clouds in cloudy periods using solar background signals. This indicates that, in general, it may be possible to retrieve both aerosol and cloud properties using a single lidar. Thus, lidar observations have great untapped potential to study interactions between clouds and aerosols
