Developing collaborative partnerships with culturally and linguistically diverse families during the IEP process
Family participation in the special education process has been federally mandated for 40 years, and educators recognize that effective collaboration with their students’ families leads to improved academic and social outcomes for students. However, while some family-school relationships are positive and collaborative, many are not, particularly for culturally and linguistically diverse (CLD) families. This article provides practice guidelines based in research for teachers who seek to improve their practices when working with CLD families who have children served by special education

Out of Focus and Into the Frame: Information Skills Benchmarking at the University of Queensland Library
This paper describes the University of Queensland Library's 1999 Information Skills benchmarking project. Particular reference is made to focus group methodology and findings. Customer based criteria for the design, and redesign, of Information Skills Programs in academic libraries are discussed
First year student expectations: Results from a university-wide student survey
Although much has been written on the first-year experience of students at higher education institutions, less attention has been directed to the expectations of students when they enter an institution for the first time. This paper provides additional insights into the expectations of students at an Australian university and highlights areas in which students’ expectations may not necessarily align with the realities of common university practices. By providing opportunities for students to articulate their expectations, staff are able to use the responses for a constructive dialogue and work towards a more positive alignment between perceived expectations and levels of student satisfaction with their experience.Geoffrey Crisp, Edward Palmer, Deborah Turnbull, Ted Nettelbeck, Lynn Ward, Amanda LeCouteur, Aspa Sarris, Peter Strelan, and Luke Schneide
Resonance absorption of a broadband laser pulse
Broad bandwidth, infrared light sources have the potential to revolutionize
inertial confinement fusion (ICF) by suppressing laser-plasma instabilities.
There is, however, a tradeoff: The broad bandwidth precludes high efficiency
conversion to the ultraviolet, where laser-plasma interactions are weaker.
Operation in the infrared could intensify the role of resonance absorption, an
effect long suspected to be the shortcoming of early ICF experiments. Here we
present simulations exploring the effect of bandwidth on resonance absorption.
In the linear regime, bandwidth has little effect on resonance absorption; in
the nonlinear regime, bandwidth suppresses enhanced absorption resulting from
the electromagnetic decay instability. These findings evince that regardless of
bandwidth, an ICF implosion will confront at least linear levels of resonance
absorption
Ultra-portable explosives sensor based on a CMOS fluorescence lifetime analysis micro-system
The paper published in AIP Advances (a new journal from the American Institute of Physics) had 1100 article downloads in the first 5 months after publication, and was on the journal’s “most read” list for 4 months. The work was featured by AIP in a Physics News Highlight and press release which resulted in >50 international internet articles and an article in Laser Focus World.This work explores the use of a green-light-emitting copolymer as a chemosensor to detect nitroaromatic-based explosive vapors by recording photoluminescence (PL) and time-resolved PL decay. We show successful detection of 10 ppb 1,4-dinitrobenzene (DNB) vapor. Both a conventional time-correlated single photon counting (TCSPC) device and CMOS time-resolved fluorescence lifetime microsystem are used in the DNB detection. An ultra-portable on-site explosive sensor based on the micro-system has also been demonstrated. This gives rise to the potential for real-time, reliable, inexpensive organic/inorganic hybrid explosives detection.Peer reviewe
Magnetothermal transport in the spin-1/2 chains of copper pyrazine dinitrate
We present experiments on the thermal transport in the spin-1/2 chain
compound copper pyrazine dinitrate Cu(C_4 H_4 N_2)(NO_3)_2. The heat
conductivity shows a surprisingly strong dependence on the applied magnetic
field B, characterized at low temperatures by two main features. The first one
appearing at low B is a characteristic dip located at mu_B B ~ k_B T, that may
arise from Umklapp scattering. The second one is a plateau-like feature in the
quantum critical regime, mu_B |B-B_c| < k_B T, where B_c is the saturation
field at T=0. The latter feature clearly points towards a momentum and field
independent mean free path of the spin excitations, contrary to theoretical
expectations.Comment: 4 pages, 4 figure
Optical properties of a light-emitting polymer directly patterned by soft lithography
Copyright © 2002 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics. The following article appeared in Applied Physics Letters 81 (2002) and may be found at http://link.aip.org/link/?APPLAB/81/1955/1We present the optical properties of a directly patterned light-emitting polymer. The patterned poly(2-methoxy-5-(3',7'-dimethyloctyloxy)-paraphenylenevinylene film is fabricated using hot embossing lithography. The effect of the embossed microstructure on the light emitted from the polymer is examined by measuring the angle-dependent photoluminescence and its photonic band structure. The imposed grating modifies the emitted light by Bragg scattering into free space light that would otherwise be trapped as waveguide modes. This simple patterning technique may find application in improving the performance of light-emitting polymer devices
