Deshler and the Know Nothing Party
No full textCharles D. Deshler, druggist, editor, author, and one of the most active political leaders of the Know Nothing Party, left at his death a large body of manuscripts which were the collections of a lifetime of contacts with some of the most prominent Americans of the last half of the nineteenth century. His son Charles Deshler of the Class of 1885, presented this group of papers to the Library
Improving Word Identification Skills Using Strategic Instruction Model (SIM) Strategies (NCSET Research to Practice Brief)
No full textA brief (written for general education teachers, special education teachers, and school administrators) focusing on the Word Identification Strategy component of the Strategic Instruction Model (SIM), (Deshler & Schumaker, 1988), and reviewing recent research showing the effectiveness of this strategy for teaching word decoding to secondary students with disabilities. The brief includes examples of how the strategy works, plus additional resources.This report was supported in whole or in part by the U.S. Department of Education, Office of Special Education Programs, (Cooperative Agreement No. H326J000005).

Polar stratospheric clouds due to vapor enhancement: HALOE observations of the Antarctic vortex in 1993
No full textComparison of Antarctic polar stratospheric cloud observations by ground-based and space-borne lidar and relevance for chemistry-climate models
No full textA comparison of polar stratospheric cloud (PSC) occurrence from 2006 to 2010 is presented, as observed from the ground-based lidar station at McMurdo (Antarctica) and by the satellite-borne CALIOP lidar (Cloud-Aerosol Lidar with Orthogonal Polarization) measuring over McMurdo. McMurdo (Antarctica) is one of the primary lidar stations for aerosol measurements of the NDACC (Network for Detection of Atmospheric Climate Change). The ground-based observations have been classified with an algorithm derived from the recent v2 detection and classification scheme, used to classify PSCs observed by CALIOP. A statistical approach has been used to compare groundbased and satellite-based observations, since point-to-point comparison is often troublesome due to the intrinsic differences in the observation geometries and the imperfect overlap of the observed areas. A comparison of space-borne lidar observations and a selection of simulations obtained from chemistry-climate models (CCMs) has been made by using a series of quantitative diagnostics based on the statistical occurrence of different PSC types. The distribution of PSCs over Antarctica, calculated by several CCMVal-2 and CCMI chemistry-climate models has been compared with the PSC coverage observed by the satellite-borne CALIOP lidar. The use of several diagnostic tools, including the temperature dependence of the PSC occurrences, evidences the merits and flaws of the different models. The diagnostic methods have been defined to overcome (at least partially) the possible differences due to the resolution of the models and to identify differences due to microphysics (e.g., the dependence of PSC occurrence on T -TNAT). A significant temperature bias of most models has been observed, as well as a limited ability to reproduce the longitudinal variations in PSC occurrences observed by CALIOP. In particular, a strong temperature bias has been observed in CCMVal-2 models with a strong impact on PSC formation. The WACCM-CCMI (Whole Atmosphere Community Climate Model - Chemistry-Climate Model Initiative) model compares rather well with the CALIOP observations, although a temperature bias is still present
Fashioning Social Aspiration: lower-middle-class rational recreational leisure participation and the evolution of popular rational recreational leisure clothing c.1880-1950
No full textIn the opening chapter of David Kynaston's Austerity Britain, entitled 'Broad Vistas', a vision of post-war Britain is contrasted with the realities of life in the years immediately following the end of the War in Europe in 1945.1 In a long introductory paragraph, Kynaston differentiates the two eras in terms of a huge list of 'haves' -comer shops, mangles, back-to-backs, Woodbines, Fynnon salts and so on -and an equally long list of exemplary 'have not yets' -supermarkets, motorways, teabags, frozen food, legalized abortions, washing machines etc. Towards the end ofthis list he finally reaches clothing, the wartime 'haves' being: 'Suits and hats, dresses and hats, cloth caps and mufflers, no leisurewear (my emphasis), no "teenagers". Heavy coins, heavy shoes, heavy suitcases, heavy tweed coats, heavy leather footballs, no unbearable lightness of being.' For Kynaston, 'leisurewear' like all the other perceived benefits of life beyond austerity is situated as part of a panorama of affiuence realized through leisure and consumption, and as representative of Britain on the threshold of something else -arguably better, as yet unavailable, but by mere association something younger, freer and lighter. What is 'leisurewear'? And why is it conceptualized as a post-austerity phenomenon? Leisure certainly existed before this time, and shifting forms of leisure clothing have shared its long history. Yet, Kynaston's reference to a new, allinclusive nomenclature forged in a pivotal period in British history, implicitly suggests that the term in itself functions as trigger to a whole network of meanings around radical social and sartorial change.

Technical Note: Evaporation of polar stratospheric cloud particles, in situ, in a heated inlet
No full textIn December 2001 and 2002 in situ aerosol measurements were made from balloon-borne platforms within polar stratospheric clouds (PSC) which contained particles of supercooled ternary solution (STS), nitric acid trihydrate (NAT) and ice. Particle size and number concentrations were measured with two optical particle counters. One of these included an ~80cm inlet heated to K to evaporate the PSC particles and thus to obtain measurements, within PSCs, of the size distribution of the particles upon which the PSCs condensed. These measurements are compared to models, described here, that calculate the evaporation of PSC particles at and for an inlet transition time of about 0.1s. The modeled evaporation for STS agrees well with the measurements. For NAT the modeled evaporation is less than the evaporation measured. The primary uncertainty concerns the phase and morphology of NAT particles as they are brought to temperatures >50K above equilibrium temperatures for NAT at stratospheric partial pressures. The slow evaporation of NAT in heated inlets could be used to identify a small NAT component within a mixed phase PSC dominated by STS
