Assessing Allied Health and Nursing Post-Secondary Career and Technical Education Teacher Attitudes and Beliefs About Reading (open access)

Assessing Allied Health and Nursing Post-Secondary Career and Technical Education Teacher Attitudes and Beliefs About Reading

This study examined allied health and nursing career and technical education (CTE) teacher beliefs and attitudes about reading. Since beliefs and attitudes influence the way teachers teach, it is important to understand what those beliefs and attitudes are, especially in relationship to reading in subject matter classrooms. One hundred twelve individuals responded to a written survey concerning their attitudes and beliefs about reading. A four-factor solution was achieved with a principal components factor analysis. A significant number of variables were associated with the factor labeled Reading Apathy, which appears to be indicative of the condition known as aliteracy among faculty who participated in the study. Professional development activities grounded in novice-to-expert theory are suggested as a way of overcoming the phenomenon. Recommendations for future research involve a more detailed study to further characterize the condition of aliteracy and its impact on student learning.

Assessing the Adlerian Personality Priorities: A Formal Instrument for Therapeutic Practice (open access)

Assessing the Adlerian Personality Priorities: A Formal Instrument for Therapeutic Practice

The purpose of this study was to develop an effective formal instrument to assess the Adlerian personality priorities. The development of the Allen Assessment for Adlerian Personality Priorities, AAAPP, seeks to provide a strong comparability to assessing the Adlerian construct of personality priorities as the counselor interview. One hundred and seven participants were given the 1st administration of the AAAPP, Social Interest Scale and a demographic survey. Sixty-four participants completed a 2nd administration of the AAAPP two weeks later. Twenty participants experienced a counseling interview following the 2nd administration. The methods used to evaluate the validity and effectiveness of the AAAPP included: face validity, predictive validity, construct validity, test-retest reliability, multiple regression, Guttman split-half reliability and the Spearman Brown reliability.

Assessment of High-Temperature Measurements for Use in the Gas Test Loop (open access)

Assessment of High-Temperature Measurements for Use in the Gas Test Loop

Temperature transducers capable of control and test measurements in the 1400-1800¢ªC range in the fast neutron irradiation environment of the Gas Test Loop are evaluated. Among the instruments discussed are high-temperature thermocouples, resistance temperature detectors, ultrasonic thermometers, noise thermometers, and optical temperature sensors. High-temperature capability, behavior under irradiation, technical maturity, cost, and availability are among the key factors considered in assessing the relative merits of each measurement method. In the near term, the doped molybdenum versus niobium-zirconium alloy thermocouple is deemed to be best suited to the in-pile test and control requirements. Additional characterization of this thermocouple combination is needed to ensure confidence in its performance. Use of tungsten-rhenium alloy thermocouples, with specific disadvantages noted, constitutes the recommended back-up position.

Assessment of Potential for Ion Driven Fast Ignition (open access)

Assessment of Potential for Ion Driven Fast Ignition

Critical issues and ion beam requirements are explored for fast ignition using ion beams to provide fuel compression using indirect drive and to provide separate short pulse ignition heating using direct drive. Several ion species with different hohlraum geometries are considered for both accelerator-produced and laser-produced ion ignition beams. Ion-driven fast ignition targets are projected to have modestly higher gains than with conventional heavy-ion fusion, and may offer some other advantages for target fabrication and for use of advanced fuels. However, much more analysis and experiments are needed before conclusions can be drawn regarding the feasibility for meeting the ion beam transverse and longitudinal emittances, focal spots, pulse lengths, and target stand-off distances required for ion-driven fast ignition.

An Assessment of Radiation Damage Models and Methods (open access)

An Assessment of Radiation Damage Models and Methods

The current state of development of the primary models used for investigating and simulating irradiation effects in structural alloys of interest to the U.S. DOE's Generation-IV reactor program are discussed. The underlying theory that supports model development is also described where appropriate. First, the key processes that underlie radiation-induced changes in material properties are summarized, and the types of radiation effects that subsequently arise are described. Future development work needed in order for theory, modeling, and computational materials science to support and add value to the Gen IV reactor materials program are then outlined. The expected specific outcomes and overall benefits of the required effort are: the knowledge to extrapolate material behavior to conditions for which there are no experimental data; systematic understanding of mechanisms and processes to enable confident interpolation between point-by-point experimental observations; acceleration of the development, selection, and qualification of materials for reactor service; and prediction of material response to real-world operating load histories which often involve a complicated superposition of time, temperature, radiation dose rate, and mechanical loading conditions. Opportunities for international collaboration to accelerate progress in all of the required research areas are briefly discussed, particularly in the context of two well coordinated, broad-based research …

B-hadron lifetimes and Delta Gamma at the Tevatron

The authors present new results on the lifetimes and widths of B hadrons based on 300-450 pb{sup -1} of data collected by CDF and D0 at the Fermilab Tevatron. Lifetimes were measured in semileptonic decays as well as fully reconstructed hadronic modes. A new measurement of the width difference between B{sub s} CP eigenstates, {Delta}{Lambda}/{bar {Lambda}}, in B{sub s} decays to J/{psi}{phi} is also presented.

B lifetimes and mixing at the Tevatron

The authors present recent results on b-hadron lifetimes and mixing obtained from the analysis of the data collected at the Tevatron Collider by the CDF and D0 Collaborations in the period 2002-2004. Many lifetime measurements have been updated since the Summer 2004 conferences, sometimes improving significantly the accuracy. Likewise the measurement of the B{sub d} oscillation frequency has been updated. New limits on the B{sub s} oscillation frequency have been determined using for the first time Run II data.

Barrier RF system and applications in Main Injector (open access)

Barrier RF system and applications in Main Injector

A novel broadband RF system--the barrier RF--has been designed, fabricated and installed in the Fermilab Main Injector (MI). It uses nanocrystal magnetic alloy called Finemet and high voltage fast MOSFET switches. The system delivers {+-}10 kV square pulses at 90 kHz. It can stack two proton batches injected from the Booster and squeeze them into the size of one so that the bunch intensity is increased. The high intensity beams have been successfully accelerated to 120 GeV with small losses. The problem of large longitudinal emittance growth is under investigation. A second system will be installed during the fall shutdown and be tested for the so-called fast stacking scheme to continuously stack up to 12 Booster batches in the MI. This system is also used for cleaning up the leaking-out dc beams from slip stacking to reduce beam loss. This work is part of the US-Japan collaborative agreement.

Beam-beam effects in the Tevatron Run II (open access)

Beam-beam effects in the Tevatron Run II

Electromagnetic long-range and head-on interactions of high intensity proton and antiproton beams are significant sources of beam loss and lifetime limitations in the Tevatron Collider Run II (2001-present). We present observations of the beam-beam phenomena in the Tevatron and results of relevant beam studies. We analyze the data and various methods employed in high energy physics (HEP) operation, predict the performance for planned luminosity upgrades and discuss ways to improve it.

Beam collimation and machine detector interface at the International Linear Collider (open access)

Beam collimation and machine detector interface at the International Linear Collider

Synchrotron radiation, beam-gas scattering and beam halo interactions with collimators and other components in the ILC beam delivery system (BDS) would create fluxes of muons and other secondaries which could exceed the tolerable levels at a detector by a few orders of magnitude. It is shown that with a multi-stage collimation system, magnetized iron spoilers which fill the tunnel and a set of masks in the detector, one can hopefully meet the design goals. Results of modeling with the STRUCT and MARS15 codes of beam loss and energy deposition effects are presented in this paper. We focus on the collimation system and mask performance optimization, short- and long-term survivability of the critical components (spoilers, absorbers and magnets), dynamic heat loads and radiation levels in magnets and other components, and machine-related backgrounds in collider detectors.

Beta function measurement in the Tevatron using quadrupole gradient modulation (open access)

Beta function measurement in the Tevatron using quadrupole gradient modulation

Early in Run2, there was an effort to compare the different emittance measurements in the Tevatron (flying wires and synchrotron light) and understand the origin of the observed differences. To measure the beta function at a few key locations near the instruments, air-core quadrupoles were installed. By modulating the gradient of these magnets and measuring the effect on the tune, the lattice parameters can be extracted. Initially, the results seem to disagree with other methods. At the time, the lattice was strongly coupled due to a skew component in the main dipoles, caused by sagging of the cryostat. After a large fraction of the superconducting magnets were shimmed to remove a strong skew quadrupole component, the results now agree with the theoretical values to within 20%.

A Betatron tune fitting package for the Tevatron 21.4 MHz Schottky (open access)

A Betatron tune fitting package for the Tevatron 21.4 MHz Schottky

The Fermilab Tevatron is equipped with two independent Schottky monitors for measurement of betatron tunes, one operating at 21.4 MHz and the other at 1.7 GHz. A new front-end and related data acquisition for the 21.4 MHz resonator has been installed and commissioned during the FY04 Collider RunII. Sophisticated fitting strategies are required to analyze the spectra. Optimization of this fitting package allows us to report tune and chromaticity measurements at almost 1 Hz.

Betatron tune spread generation and differential chromaticity control by octupole families at Tevatron (open access)

Betatron tune spread generation and differential chromaticity control by octupole families at Tevatron

Existing Tevatron octupoles have been rearranged into four functional families. Two of these families generate betatron tune spreads in the vertical and horizontal planes whereas the other two control the differential chromaticity between the proton and antiproton helices. The calculated effect on the tunes and chromaticity is compared with direct measurements. Analytical formulas for betatron tune distribution functions are presented.

Booster 6-GeV study (open access)

Booster 6-GeV study

A wider aperture, which has been obtained along the Booster beam line recently, brings the opportunity to run beams with the intensity higher than ever before. Sooner or later, the available RF accelerating voltage will become a new limit for the beam intensity. Extra accelerating voltages can be achieved either by increasing the RFSUM or by reducing the accelerating rate via a slower acceleration, and this motivates the 6-GeV study.

The breakdown of de Gennes Scaling in TbxEr1-xNi2B2C and its mean field theory explanation (open access)

The breakdown of de Gennes Scaling in TbxEr1-xNi2B2C and its mean field theory explanation

The Neel temperatures, T{sub N}, of Tb{sub x}Er{sub 1-x}Ni{sub 2}B{sub 2}C samples have been determined from the temperature dependence of magnetization measurements. A breakdown of the de Gennes scaling of T{sub N} with a clear turning point around x = 0.45 has been observed. The T{sub N} values of Tb{sub x}Er{sub 1-x}Ni{sub 2}B{sub 2}C do not change much within the range of O < x < 0.45 and then, for larger x they increase almost linearly with concentration until T{sub N} = 14.9K is reached for x = 1, TbNi{sub 2}B{sub 2}C. The clear change in the x-dependence of T{sub N} around x = 0.45 can be linked to a change in the local moment ordering direction from transverse to longitudinal, a change which is consistent with recent resonant X-ray scattering data. These features in T{sub N}(x) can be explained using a mean field model.
