What do parents perceive to be effective characteristics of a family literacy program? An action research project
Creators: name: Jamieson, Nicole
Publisher: name: Vancouver Island University - Royal Roads University
Year: 2012
Subjects: subject: Family literacy programs

description: This study examined how a Grade 1/2 teacher implemented a family literacy program for the families of the children in her class. Using action research, this research study asked the question, “What do parents perceive to be effective characteristics of a family literacy program?” The researcher implemented a family literacy program for a six-week period in her classroom. Before beginning the study, the researcher invited parents to participate in an information evening designed to provide ideas and strategies for reading with their child at home. After the six-week study period, data was collected in the form of a survey. Through literature review, analyzing both qualitative and quantitative data, and reflecting on the feedback from participants, this study provided the researcher with information to guide the development of her family literacy program. The data collected during this study showed that parents found the family literacy program effective when children were able to choose their own books and were taking books home every night.

description: First Steps in Mathematics, a mathematics professional development program being delivered in a Vancouver Island school district, was examined with the purpose of determining its impact on teacher practice. Factors that led to elementary teachers? ability to implement and/or continue to practice components of the program were identified. Mixed methods research following an explanatory design was conducted on the four cohorts of teachers who had completed or were participating in the training. The 116 eligible participants were invited to complete an on-line survey which collected both quantitative and qualitative data. From the 71 participants who completed the survey, four key informants who had demonstrated extensive implementation and continued use were selected and interviewed. An increase in teacher efficacy was found. Teachers' mathematical understanding increased as well as their preparedness to teach mathematics in all aspects of the curriculum, even those that extended beyond the scope of the course. Key factors that contributed to program implementation included: its ease of use, the ability to plan for instruction as well as the monitoring of student growth. Key factors that contributed to the program?s continued use were similar to implementation but also included the influence of support from school-based and district-based colleagues including curriculum support teachers, learning support teachers, district numeracy support and program facilitator support. Recommendations were then made to the school district and the Island Numeracy Network. The author determined that it was important to continue with the current level of support for the First Steps in Mathematics program in the school district, including the funding of the training and the continued development of resources to support the program, specifically the locally developed course binders and website. Formal and informal leadership was determined to be an important part of the program?s success and therefore aspects of it - particularly involving - leadership and collaboration should be expanded.

description: Optics East, 9-12 SEPTEMBER 2007, Boston, MA, United States
description: Across extracellular surfaces, lipid rafts are believed to be an important organizing membrane microdomain component, facilitating specific protein-protein interactions by selectively excluding or including proteins into them. The lipid-based sorting mechanism of these microdomains has been implicated in many cellular processes including; membrane trafficking, signal transduction and cell growth regulation. However, since individual rafts are estimated to range in size from the nanoscale to the microscale, in many cases, they cannot be easily monitored by conventional imaging techniques. We have developed surface enhanced Raman scattering (SERS)-based nanoimaging probes for nanoscale imaging of biochemical species on and within extracellular environments. These probes synergistically combine the qualitative and quantitative information of SERS with the nanoscale imaging capabilities of tapered fiber optic bundles, potentially allowing for chemical imaging of extracellular components and chemical exchange events across cellular surfaces. These probes are fabricated from coherent fiber optic bundles containing 30,000 individual fiber elements that have been tapered to have diameters as small as 140 nm, thus allowing for image magnification and submicron spatial resolution. Due to the uniformly roughened surface features across the probe's imaging surface onto which silver island arrays are fabricated, these probes exhibit less than 3% RSD in SERS signal across the imaging area. In this work, tunability, multiplex detection capabilities and an application of these SERS nanoimaging probes to biological systems are demonstrated.
Developing a shared vision to improve collaborative learning

Subjects: subject: Teaching teams

description: Each day Cafeteria Training students work collaboratively to perform daily tasks. However, challenges arise associated with collaboration that requires teacher intervention. An approach to address this concern was to involve students in developing a shared vision. By having students develop a shared vision this would increase classroom sense of community and therefore improve the collaborative effort of Cafeteria Training students. A quantitative study was conducted with 14 Cafeteria Training students that measured their perceived sense of community before and after developing a shared vision. Students reported noteworthy improvements to their sense of classroom community, caring for one another, student support, and the feeling of family.

description: In 2004, Csörgő constructed a loop of nilpotency class three with abelian group of inner mappings. Until now, no other examples were known. We construct many such loops from groups of nilpotency class two by replacing the product $xy$ with $xyh$ in certain positions, where $h$ is a central involution. The location of the replacements is ultimately governed by a symmetric trilinear alternating form.

SERS probes for the detection and imaging of biochemical species on the nanoscale

description: Optics East 2006, 1-4 OCTOBER 2006, Boston, Massachusetts, United States
description: We have developed novel surface enhanced Raman scattering (SERS)-based nanoimaging probes for dynamic chemical imaging in a non-scanning format. These probes have been developed for obtaining sub-diffraction limited chemical measurements of various biochemical species (e.g., lipids, proteins, etc.) as well as biological organisms (e.g., bacteria, etc.). They combine qualitative and quantitative information obtained from SERS with the imaging capabilities of coherent fiber optic bundles. Nanoimaging probes are fabricated from coherent fiber optic bundles composed of 30,000 individual 4 μm diameter fiber elements. Using a CO2 laser based micropipette puller, bundles are tapered on one end resulting in the formation of equi-diameter individual elements tens of nanometers to hundreds of nanometers in diameter. Employing these probes, inherent image magnification and submicron spatial resolution is possible. Across these tapered probe tips, uniformly roughened surface features are creating by HF acid etching. These surface features consist of six cladding peaks that surround each individual fiber elements' core, which are uniform in size, shape, structure, and spacing. SERS active surfaces are created on the tapered tips of the probes by selectively depositing silver onto these cladding peaks, creating an array of highly ordered uniform silver islands across these nanoimaging probes' surfaces. This fabrication process results in a high degree of uniformity in SERS enhancement across the image surface of the probes (< 3.0% RSD), which is essential for reproducible quantitative imaging applications. Further SERS enhancement and specific excitation wavelength tuning can be achieved by controlling the spacing between silver islands and the overall size of the silver islands uniformly arrayed across these SERS probe tips. Characterization and imaging of biochemical species and model compounds using these SERS nanoimaging probes is presented in this manuscript.

description: A detailed study of SERS enhancements from novel multilayer gold film over nanoparticle (GFON) substrates is presented. These multilayer GFON substrates were optimized in terms of the number of metal layers, and the amounts of gold and silver oxide deposited. These multilayer GFON substrates were also structurally characterized in terms of surface roughness. No significant changes in the surface roughness of these multilayer GFON substrates, even with different layers of gold, have been observed, suggesting there is no direct correlation between the multilayer SERS enhancements and the surface roughness. UV-Vis reflectance spectra of these substrates were also characterized, indicating that the significant multilayer enhancements require the presence of silver oxide layers separating the continuous gold film layers.

description: We have developed a novel class of surface-enhanced Raman scattering (SERS)-based nanoimaging probes for chemical imaging with nanometer scale spatial resolution. Using these SERS nanoimaging probes it is possible to differentiate between different chemical components within the sample under analysis. These SERS nanoimaging probes are fabricated from coherent fiber optic imaging bundles composed of 30,000 individual image transmission elements. Using a specially programmed micropipette puller, the individual fiber elements are uniformly heated and pulled, creating a tapered bundle with a flat tip. In order to create the SERS active surface, the tapered end of the fiber bundle is roughened on the "molecular scale" via chemical etching, and is then over-coated with silver in a controlled manner via vapor deposition in a vacuum evaporator. Following etching, six regularly spaced peaks are produced surrounding each of the individual image transmission elements of the bundle, and it is these peaks onto which the metal over-layer is deposited. Due to the high degree of uniformity in the surface of these tapered and etched tips, these SERS nanoimaging probes exhibit significantly greater reproducibility than SERS substrates fabricated through similar silver film over nanostructure fabrication processes. Characterization and optimization of these SERS nanoimaging probes using SERS active chemicals is discussed.

description: Brain cancer affects approximately 16,500 people a year and individuals diagnosed with glioblastoma multiforme have an average life expectancy of less than 12-18 months after diagnosis. A portable fiber-optic probe capable of distinguishing between healthy and tumor tissues, with a high degree of spatial resolution, deep within a sample would be a valuable tool for tumor diagnosis and margining. A novel technique that combines 1-2 cm penetration depths with cellular level spatial resolution to chemically distinguish cancerous from non-cancerous tissues is non-resonant multiphoton photoacoustic spectroscopy (NMPPAS). This technique focuses pulsed near infrared light into a sample, creating a two-photon excitation event, and measures the resulting non-radiative decay as an ultrasonic signal. This paper discusses the optimization of a portable fiber-optic NMPPAS probe capable of delivering nanosecond laser pulses from 740nm-1100nm to a series of lens, which focus the light into the sample. The resulting ultrasonic signal is measured using a polyvinylidene fluoride based piezoelectric detector. The two-photon excitation efficiency of the portable NMPPAS probe system has been evaluated by measuring the two-photon excitation and emission spectra of common fluorescent dyes such as rhodamine B and fluorescein. In addition, this paper also demonstrates the diagnostic potential of this technique for tumor detection and margining without the need for acquisition of an entire spectrum.

Dreaming Up Snow: Registration, Restriction and Radicalization of Russian NGOs 2000-2010

description: Following the chaotic first years after the fall of the Soviet Union nongovernmental organizations (NGOs) have tried to create a vibrant and healthy civil society in modern Russia. While many of these NGOs have flourished in this period, others have experienced repression at the hand of state actors. One form of repression is differential application of registration, anti-extremism, and tax laws against specific types of NGOs in a way to exclude them from, or make it difficult to participate in, the arena of sanctioned activity. Which NGOs are targeted by differential application, and how they respond if pushed to the point of liquidation is determined by different organizational characteristics. One of these responses is an unintended consequence of such state repression, unsanctioned political protest. This thesis addresses the organizational characteristics that attract differential application and explores the outcomes following the liquidation of NGOs as a result of such repression.

We point out that neutron emission by the heavy fragments can be treated in effective theory if corrections to the velocity distribution are needed.

Here, we survey several proven instrument designs that can be readily implemented in any laboratory setting to achieve synchrotron-quality XAFS and XES for many systems in the 5 keV to 10 keV energy range. These approaches are based on our immediate experience with the development of: (1) an inexpensive, low-powered monochromator capable of performing either XAFS or XES, (2) a mid-scale XAFS user facility having 10^6/sec flux with sub-eV bandwidth on each of two independent beamlines, and (3) multiple XES spectrometers having 3rd-generation synchrotron performance for battery and actinide research.

description: We have developed and optimized novel nanosphere-based silver coated SERS substrates for the detection of proteins. These SERS substrates were optimized for silver thickness, number of silver layers, and extent of silver oxidation between layers. Immuno-nanosensors capable of being inserted into individual cells and non-invasively positioned to the sub-cellular location of interest using optical tweezers were constructed from monodisperse silica nanospheres. Silica nanospheres ranging in diameter from 100 to 4500 nm were condensed from tetraalkoxysilanes in an alcoholic solution of water and ammonia. By varying the reaction conditions, accurate control of the silica nanospheres’ diameter was achieved. Silica sphere sizes were optimized for SERS signal response. Nanosphere-based SERS substrates were made by depositing multiple layers of silver on the nanospheres, followed by binding of the antibody of interest to the silver. In binding the antibodies, different crosslinkers were characterized and compared. On one end, each of these crosslinkers contained sulfur or isothiocyanate groups which bound to the silver surface, while the other end contained a carboxylic or primary amine group which reacted readily with the antibodies. In order to evaluate these substrates, SERS spectra of different proteins, such as insulin and interleukin-2 (IL-2), were obtained. By using silver, as the metal surface for SERS, red and near-infrared excitation wavelengths (i.e., 600-700 nm) can be used. Excitation in this range helps to avoid photodamage to cells and reduces any autofluorescence background. Evaluation of these SERS substrates was performed using a 10 mW HeNe laser, operating at 632.8 nm, in a collinear excitation/detection geometry. The SERS signals were filtered with a holographic notch filter, dispersed by 1/3 meter spectrometer and detected using an intensified charge coupled device (ICCD). This paper discusses the fabrication and optimization of these nanosensors, as well as their potential applications.

description: We have developed and characterized novel multilayered metal film-based surface-enhanced Raman scattering (SERS) substrates capable of enhancing SERS signals over an order of magnitude compared to conventional single layer substrates. In addition to enhanced signal intensity, these multilayered metal film substrates also exhibit longer SERS active lifetimes, higher reproducibility and lower detection limits than single layer silver substrates. Multilayered metal film substrates were fabricated by repeated vapor deposition of metal films over nanometer sized silica spheres. Different sizes of silica spheres were evaluated in order to obtain the optimal SERS enhancements. Meanwhile, different coating methods, drop coating and spin coating, were applied to form silica sphere layers that provided the roughness for SERS enhancements. These two coating methods were also compared for various silica sphere sizes by investigating their effects on the SERS enhancements. By applying additional silver layers on top of silver film over silica sphere SERS substrates, multi-layer enhancements can be observed. Additionally, different metals, such as gold, were used to further optimize the stability and reproducibility of these novel substrates. In order to speed up the fabrication of these multiple metal layer SERS substrates, silver oxide layers produced in an oven were investigated, reducing fabrication time by a factor of 50.

description: The current study explored the effect of Sustained Silent Reading and booktalks on high school students’ attitudes towards reading. The mixed methods study used a survey made up of ten Likert style questions and one open ended question to examine 24 Grade 12 English students’ attitudes after participating in Sustained Silent Reading and two booktalks. Triangulation was used to analyse and compare the quantitative and qualitative data. The study found that the participants believed that it was important to participate in daily silent reading, to have time to read when they were finished class work, and to have a large selection of books to choose from, but did not find the same importance in booktalks. Although conclusive evidence that the Sustained Silent Reading and booktalks have an effect on students’ attitude was not established, participants believed that it was important to have time to read.

description: Recently developed instrumentation at the University of Washington has allowed for nonresonant x-ray emission spectra (XES) to be measured in a laboratory-setting with an inexpensive, easily operated system. We present a critical evaluation of this equipment by means of K\b{eta} and valence-level XES measurements for several Co compounds. We find peak count rates of ~5000/s for concentrated samples and a robust relative energy scale with reproducibility of 25 meV or better. We furthermore find excellent agreement with synchrotron measurements with only modest loss in energy resolution. Instruments such as ours, based on only conventional sources that are widely sold for elemental analysis by x-ray fluorescence, can fill an important role to diversify the research applications of XES both by their presence in non-synchrotron laboratories and by their use in conjunction with XAFS beamlines where the complementarity of XAFS and XES holds high scientific potential.

Replication - The effect of BW vs. Color Imagery on Pride and Joy_ Update

description: In a preliminary experiment we found that BW (versus color) imagery differentially influenced the intensity of joy and pride. Specifically, we found that images elicited a more intense positive emotional response when presented in color than in BW. Importantly, this effect was less pronounced for pride than for joy images. In this previous study, we realized after collecting the data that some of the joy-eliciting images were more colorful and detailed than the pride-eliciting images. The goal of the present experiment is to overcome this possible confound, by replicating the effect of color on emotion intensity, with joy and pride images that were pretested and found to be not statistically different in their degree of color and details.

description: Variation of the phase of the beam transmitted through a crystalline material as a function of the rocking angle is a well known dynamical effect in x-ray scattering. Unfortunately, it is not so easy to measure directly these phase variations in a conventional scattering experiment. It was recently suggested that the transmitted phase can be directly measured in ptychography experiments performed on nanocrystal samples. Results of such experiment for different crystal thickness, reflections and incoming photon energies, in principle, can be fully described in the frame of dynamical theory. However, dynamical theory does not provide a simple analytical expression for the further analysis. We develop here quasi-kinematical theory approach that allows to describe correctly the phase of the transmitted beam for the crystal thickness less than extinction length that is beyond applicability of the conventional kinematical theory.

Microwave excitation of spin wave beams in thin ferromagnetic films

description: We present an approach enabling generation of narrow spin wave beams in thin homogeneous ferromagnetic films. The main idea is to match the wave vector of the spin wave with that corresponding to the spectral maximum of the exciting microwave magnetic field only locally, in the region of space from which the beam should be launched. We show that this can be achieved with the aid of a properly designed coplanar waveguide transducer generating a nonuniform microwave magnetic field. The resulting two-dimensional spin wave beams obtained in micromagnetic simulations propagate over distances of several micrometers. The proposed approach requires neither inhomogeneity of the ferromagnetic film nor nonuniformity of the biasing magnetic field, and it can be generalized to yield multiple spin wave beams of different width at the same frequency. Other possible excitation scenarios and applications of spin wave beam magnonics are also discussed.
Analysis of the $Wtb$ vertex from the measurement of triple-differential angular decay rates of single top quarks produced in the $t$-channel at $\sqrt{s}$ = 8 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: The electroweak production and subsequent decay of single top quarks in the $t$-channel is determined by the properties of the $Wtb$ vertex, which can be described by the complex parameters of an effective Lagrangian. An analysis of a triple-differential decay rate in $t$-channel production is used to simultaneously determine five generalised helicity fractions and phases, as well as the polarisation of the produced top quark. The complex parameters are then constrained. This analysis is based on 20.2 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 8 TeV collected with the ATLAS detector at the LHC. The fraction of decays containing transversely polarised $W$ bosons is measured to be $f_1=0.30 \pm 0.05$. The phase between amplitudes for transversely and longitudinally polarised $W$ bosons recoiling against left-handed $b$-quarks, is measured to be $\delta_- = 0.002\pi^{+0.016\pi}_{-0.017\pi}$, giving no indication of CP violation. The fraction of longitudinal or transverse $W$ bosons accompanied by right-handed $b$-quarks are also constrained. Based on these measurements, limits are placed at 95% C.L. on the ratio of the complex coupling parameters Re$[g_\mathrm{R}/V_\mathrm{L}] \in [-0.12,0.17]$ and Im$[g_\mathrm{R}/V_\mathrm{L}] \in [-0.07,0.06]$. Constraints are also placed on the ratios $|V_\mathrm{R}/V_\mathrm{L}|$ and $|g_\mathrm{L}/V_\mathrm{L}|$. In addition, the polarisation of single top quarks in the $t$-channel is constrained to be $P > 0.72$ (95% C.L.). None of the above measurements make assumptions on the value of any of the other parameters or couplings and all of them are in agreement with the Standard Model.

description: The application of large magnetic fields ($B \sim B_{c2}$) to layered cuprates suppresses their high temperature superconducting behaviour and reveals competing ground states. In the widely-studied material YBa$_2$Cu$_3$O$_{6+x}$ (YBCO), underdoped ($p \sim 1/8$) samples show signatures of field-induced electronic and structural changes at low temperatures. However, the microscopic nature of the field-induced reconstruction and the high-field state are unclear. Here we report an x-ray study of the high-field charge density wave (CDW) in YBCO, for doping, $0.1 \lesssim p \lesssim 0.13$. For $p \sim 0.123$, we find that a field ($B \sim 10$~T) induces new CDW correlations along the CuO chain ($b$) direction only, leading to a 3-D ordered state along this direction at $B \sim 15$~T. The CDW signal along the $a$-direction is also enhanced by field, but does not develop a new pattern of correlations. We find that field modifies the coupling between the CuO$_2$ bilayers in the YBCO structure, and causes the sudden appearance of 3D CDW order. The mirror symmetry of individual bilayers is broken by the CDW at low and high fields, allowing recently suggested Fermi surface reconstruction.
