Assessing the Presence and Use of Nonverbal Communication in Primary Reading Instruction

This research examined the presence and types of nonverbal communication presented in primary reading instruction. Primary instructors were surveyed about their use and types of nonverbal communication employed during reading instruction. Nonverbal communication variables studied were determined from relevant literature regarding nonverbal immediacy, primary education, and reading instruction. Findings revealed that almost all nonverbal communication variables studied were employed frequently and most respondents had no prior training. Findings suggest how future studies can better evaluate the role of nonverbal communication in reading instruction and provide education for primary teachers in hopes of improving literacy education

Claude A. Swanson of Virginia: A Political Biography

Spanning most of the years of the one-party South, the public career of Virginian Claude A. Swanson, congressman, governor, senator, and secretary of the navy, extended from the second administration of Grover Cleveland into that of Franklin Roosevelt. His record, writes Henry C. Ferrell, Jr., in this definitive biography, is that of “a skillful legislative diplomat and an exceedingly wise executive encompassed in the personality of a professional politician.” As a congressman, Swanson abandoned Cleveland\u27s laissez faire doctrines to become the leading Virginia spokesman for William Jennings Bryan and the Democratic platform of 1896. His achievements as a reform governor are equaled by few Virginia chief executives. In the Senate, Swanson worked to advance the programs of Woodrow Wilson. In the 1920s, he contributed to formulation of Democratic alternatives to Republican policies. In Roosevelt\u27s New Deal cabinet, he helped the Navy obtain favorable treatment during a decade of isolation. The warp and woof of local politics are well explicated by Ferrell to furnish insight into personalities and events that first produced, then sustained, Swanson\u27s electoral success. He examines Virginia educational, moral, and social reforms; disfranchisement movements; racial and class politics; and the impact of the woman\u27s vote. And he records the growth of the Hampton Roads military-industrial complex, which Swanson brought about. In Virginia, Swanson became a dominant political figure, and Ferrell\u27s study challenges previous interpretations of Virginia politics between 1892 and 1932 that pictured a powerful, reactionary Democratic Organization, directed by Thomas Staples Martin and his successor Harry Flood Byrd, Sr., defeating would-be progressive reformers. A forgotten Virginia emerges here, one that reveals the pervasive role of agrarians in shaping the Old Dominion\u27s politics and priorities. Henry C. Ferrell Jr. is professor of history at East Carolina University.https://uknowledge.uky.edu/upk_political_history/1013/thumbnail.jp

Proteinase-activated receptor-2 modulates human macrophage differentiation andeffector function

Proteinase-activated receptor-2 (PAR-2) was shown to influence immune regulation; however, its role in human macrophage subset development and function has not been addressed. Here, PAR-2 expression and activation was investigated on granulocyte macrophage (GM)-CSF(M1) and macrophage (M)-CSF(M2) macrophages. In both macrophages, the PAR-2-activating peptide, SLIGKV, increased PAR-2 expression and regulated TNF-α and IL-10 secretion in a manner similar to LPS. In addition, HLA-DR on M1 cells also increased. Monocytes matured to an M1 phenotype in the presence of SLIGKV had reduced cell area, and released less TNF-α after LPS challenge compared with vehicle (P < 0.05, n = 3). Cells matured to an M2 phenotype with SLIGKV also had a reduced cell area and made significantly more TNF-α after LPS exposure compared to vehicle (P < 0.05, n = 3) with reduced IL-10 secretion (P < 0.05, n = 3). Thus, PAR-2 activation on macrophage subsets regulates HLA-DR and PAR-2 surface expression, and drives cytokine production. In contrast, PAR-2 activation during M1 or M2 maturation induces altered cell morphology and skewing of phenotype, as evidenced by cytokine secretion. These data suggest a complex role for PAR-2 in macrophage biology and may have implications for macrophage-driven disease in which proteinase-rich environments can influence the immune process directly

Functional integral approach to multipoint correlators in 2d critical systems

We extend a previously developed technique for computing spin-spin critical correlators in the 2d Ising model, to the case of multiple correlations. This enables us to derive Kadanoff-Ceva's formula in a simple and elegant way. We also exploit a doubling procedure in order to evaluate the critical exponent of the polarization operator in the Baxter model. Thus we provide a rigorous proof of the relation between different exponents, in the path-integral framework.Comment: 10 pages, LaTex, no figure

Scaling of the superfluid density in high-temperature superconductors

A scaling relation \rho_s \simeq 35\sigma_{dc}T_c has been observed in the copper-oxide superconductors, where \rho_s is the strength of the superconducting condensate, T_c is the critical temperature, and \sigma_{dc} is the normal-state dc conductivity close to T_c. This scaling relation is examined within the context of a clean and dirty-limit BCS superconductor. These limits are well established for an isotropic BCS gap 2\Delta and a normal-state scattering rate 1/\tau; in the clean limit 1/\tau \ll 2\Delta, and in the dirty limit 1/\tau > 2\Delta. The dirty limit may also be defined operationally as the regime where \rho_s varies with 1/\tau. It is shown that the scaling relation \rho_s \propto \sigma_{dc}T_c is the hallmark of a BCS system in the dirty-limit. While the gap in the copper-oxide superconductors is considered to be d-wave with nodes and a gap maximum \Delta_0, if 1/\tau > 2\Delta_0 then the dirty-limit case is preserved. The scaling relation implies that the copper-oxide superconductors are likely to be in the dirty limit, and that as a result the energy scale associated with the formation of the condensate is scaling linearly with T_c. The a-b planes and the c axis also follow the same scaling relation. It is observed that the scaling behavior for the dirty limit and the Josephson effect (assuming a BCS formalism) are essentially identical, suggesting that in some regime these two effects may be viewed as equivalent. This raises the possibility that electronic inhomogeneities in the copper-oxygen planes may play an important role in the nature of the superconductivity in the copper-oxide materials.Comment: 8 pages with 5 figures and 1 tabl

The cesium powder and pellets inner container is to be performance tested per the criteria specified in Section 4.0 of HNF-2399, ``Design, Fabrication, and Assembly Criteria for Cesium Powder and Pellet Inner Container.`` The test criteria specifies that the inner container be water tight during decontamination of the exterior surface. Three prototypes will be immersed into a pool of water to simulate a water decontamination process

Safety evaluation for packaging (onsite) nitrogen trailers propane tanks

The purpose of the Safety Evaluation for Packaging (SEP) is the evaluation and authorization of the onsite transport of propane tanks that are mounted on the Lockheed Martin Hanford Corporation Characterization Project`s nitrogen trailers. This SEP authorizes onsite transport of the nitrogen trailers, including the propane tanks, until May 31, 1998. The three nitrogen trailers (HO-64-4966, HO-64-4968, and HO-64-5170) are rated for 1,361 kg (30,000 lb) and are equipped with tandem axles and pintel hitches. Permanently mounted on each trailer is a 5,678 L (1,500 gal) cryogenic dewar that is filled with nitrogen, and a propane fired water bath vaporizer system, and a 454 L (1 20 gal) propane tank. The nitrogen trailer system is operated only when it is disconnected from the tow vehicle and is leveled and stabilized. When the trailers are transported, the propane tanks are isolated via closed supply valves
