  5. PLD$ is involved in phagocytosis of microglia: expression and localization changes of PLD4 are correlated with activation state of microglia.

    Directory of Open Access Journals (Sweden)

    Yoshinori Otani

    Full Text Available Phospholipase D4 (PLD4 is a recently identified protein that is mainly expressed in the ionized calcium binding adapter molecule 1 (Iba1-positive microglia in the early postnatal mouse cerebellar white matter. Unlike PLD1 and PLD2, PLD4 exhibits no enzymatic activity for conversion of phosphatidylcholine into choline and phosphatidic acid, and its function is completely unknown. In the present study, we examined the distribution of PLD4 in mouse cerebellar white matter during development and under pathological conditions. Immunohistochemical analysis revealed that PLD4 expression was associated with microglial activation under such two different circumstances. A primary cultured microglia and microglial cell line (MG6 showed that PLD4 was mainly present in the nucleus, except the nucleolus, and expression of PLD4 was upregulated by lipopolysaccharide (LPS stimulation. In the analysis of phagocytosis of LPS-stimulated microglia, PLD4 was co-localized with phagosomes that contained BioParticles. Inhibition of PLD4 expression using PLD4 specific small interfering RNA (siRNA in MG6 cells significantly reduced the ratio of phagocytotic cell numbers. These results suggest that the increased PLD4 in the activation process is involved in phagocytosis of activated microglia in the developmental stages and pathological conditions of white matter.

    PLD-118, formerly BAY 10-8888, is a synthetic antifungal derivative of the naturally occurring beta-amino acid cispentacin. We studied the activity of PLD-118 in escalating dosages against experimental oropharyngeal and esophageal candidiasis (OPEC) caused by fluconazole (FLC)-resistant Candida albicans in immunocompromised rabbits. Infection was established by fluconazole-resistant (MIC > 64 microg/ml) clinical isolates from patients with refractory esophageal candidiasis. Antifungal therapy was administered for 7 days. Study groups consisted of untreated controls; animals receiving PLD-118 at 4, 10, 25, or 50 mg/kg of body weight/day via intravenous (i.v.) twice daily (BID) injections; animals receiving FLC at 2 mg/kg/day via i.v. BID injections; and animals receiving desoxycholate amphotericin B (DAMB) i.v. at 0.5 mg/kg/day. PLD-118- and DAMB-treated animals showed a significant dosage-dependent clearance of C. albicans from the tongue, oropharynx, and esophagus in comparison to untreated controls (P PLD-118 demonstrated nonlinear plasma pharmacokinetics across the investigated dosage range, as was evident from a dose-dependent increase in plasma clearance and a dose-dependent decrease in the area under the plasma concentration-time curve. The biochemical safety profile was similar to that of FLC. In summary, PLD-118 demonstrated dosage-dependent antifungal activity and nonlinear plasma pharmacokinetics in treatment of experimental FLC-resistant oropharyngeal and esophageal candidiasis.

    The response to radiation of seven osteosarcoma cell lines was analysed by in vitro colony-forming assay and compared with that of eight human fibroblast strains. The values of D 0 , the surviving fraction after 2 Gy (S2Gy), and the mean inactivation dose (D-bar) of osteosarcoma cells in log-phase culture were significantly higher than those of fibroblast strains (p<0.01). PLD (potentially lethal damage) repair of osteosarcoma cells evaluated in the plateau phase of growth showed great variation for enhancement of survival, although all of the values were maximised within 12 h after irradiation. In the osteosarcoma, intrinsic radiosensitivity in vitro reflected the clinical response to radiation. However, the capacity for PLD repair might not be a good indicator for predicting the results of radiation therapy. (author)

    We have developed long Gd-123 coated conductors by ion-beam-assisted deposition (IBAD) and pulsed-laser-deposition (PLD) method. Recently, large-scale reel-to-reel apparatus with the 110 cm x 15 cm assisting ion source was introduced to IBAD system. It was enable to produce 500 m-class IBAD-Gd 2 Zr 2 O 7 (GZO) tapes with Δφ of below 15 deg. and high throughputs of 3 m/h. Furthermore, apparatus with multi-lane and laser scanning was introduced to PLD system. As a result, end to end I c of 318 A were obtained for a 201.5 m long tape, and I c x L values were 64,077 Am. Furthermore, 500 m-class deposition was carried out by improving PLD conditions. As a result, I c x L values of 112,166 Am was obtained and it's a world record on August 2007. In the short samples, I c of over 500 A was obtained with Gd-123 thickness of 2.0 μm and over 100 A was obtained in magnetic field of 3 T, perpendicular to c-axis

    Long-term memory (LTM) of fear stores activity dependent modifications that include changes in amygdala signaling. Previously, we identified an enhanced probability of release of glutamate mediated signaling to be important in rat fear potentiated startle (FPS), a well-established translational behavioral measure of fear. Here, we investigated short- and long-term synaptic plasticity in FPS involving metabotropic glutamate receptors (mGluRs) and associated downstream proteomic changes in the thalamic-lateral amygdala pathway (Th-LA). Aldolase A, an inhibitor of phospholipase D (PLD), expression was reduced, concurrent with significantly elevated PLD protein expression. Blocking the PLD-mGluR signaling significantly reduced PLD activity. While transmitter release probability increased in FPS, PLD-mGluR agonist and antagonist actions were occluded. In the unpaired group (UNP), blocking the PLD-mGluR increased while activating the receptor decreased transmitter release probability, consistent with decreased synaptic potentials during tetanic stimulation. FPS Post-tetanic potentiation (PTP) immediately following long-term potentiation (LTP) induction was significantly increased. Blocking PLD-mGluR signaling prevented PTP and reduced cumulative PTP probability but not LTP maintenance in both groups. These effects are similar to those mediated through mGluR7, which is co-immunoprecipitated with PLD in FPS. Lastly, blocking mGluR-PLD in the rat amygdala was sufficient to prevent behavioral expression of fear memory. Thus, our study in the Th-LA pathway provides the first evidence for PLD as an important target of mGluR signaling in amygdala fear-associated memory. Importantly, the PLD-mGluR provides a novel therapeutic target for treating maladaptive fear memories in posttraumatic stress and anxiety disorders. Published by Elsevier Inc.

  11. Development of RPS trip logic based on PLD technology

    2012-01-01

    The majority of instrumentation and control (I and C) systems in today's nuclear power plants (NPPs) are based on analog technology. Thus, most existing I and C systems now face obsolescence problems. Existing NPPs have difficulty in repairing and replacing devices and boards during maintenance because manufacturers no longer produce the analog devices and boards used in the implemented I and C systems. Therefore, existing NPPs are replacing the obsolete analog I and C systems with advanced digital systems. New NPPs are also adopting digital I and C systems because the economic efficiencies and usability of the systems are higher than the analog I and C systems. Digital I and C systems are based on two technologies: a microprocessor based system in which software programs manage the required functions and a programmable logic device (PLD) based system in which programmable logic devices, such as field programmable gate arrays, manage the required functions. PLD based systems provide higher levels of performance compared with microprocessor based systems because PLD systems can process the data in parallel while microprocessor based systems process the data sequentially. In this research, a bistable trip logic in a reactor protection system (RPS) was developed using very high speed integrated circuits hardware description language (VHDL), which is a hardware description language used in electronic design to describe the behavior of the digital system. Functional verifications were also performed in order to verify that the bistable trip logic was designed correctly and satisfied the required specifications. For the functional verification, a random testing technique was adopted to generate test inputs for the bistable trip logic.

    In this study, porous structures were created on poly(ethylene terephthalate) (PET) by femtosecond (fs) laser micromachining. While such structures offer a texture that is desirable for several applications, their wettability does not always match the application in question. The aim of this investigation is to tune the wettability of such surfaces by incorporating a controlled amount of nanoparticles into the structure. The machined PET samples were thus used as substrates for fs pulsed laser deposition (PLD) of titanium under ambient conditions. The nanoparticles were deposited as nanochain clusters due to the formation of an oxide layer between individual nanoparticles. The stability of nanoparticle incorporation was tested by placing the samples in an ultrasonic ethanol bath. Results indicated that nanoparticles were still successfully incorporated into the microstructure after sonication. Nanoparticle surface coverage was observed to be controllable through the operating fluence. The dynamic contact angles of the resulting composite surface were observed to decrease with increasing titanium incorporation. Therefore, this work highlights atmospheric fs PLD as a method for wettability modification of high surface area microstructures without undermining their topology. In addition, this technique uses almost the same equipment as the machining process by which the microstructures are initially created, further highlighting its practicality.

    Silicon thin films have been prepared on sapphire substrates by pulsed laser deposition (PLD) technique. The films were deposited in vacuum from a silicon target at a base pressure of 10 -6 mbar in the temperature range from 400 to 800 deg. C. A Q-switched Nd:YAG laser (1064 nm, 5 ns duration, 10 Hz) at a constant energy density of 2 J x cm -2 has been used. The influence of the substrate temperature on the structural, morphological and optical properties of the Si thin films was investigated. Spectral ellipsometry and atomic force microscopy (AFM) were used to study the thickness and the surface roughness of the deposited films. Surface roughness values measured by AFM and ellipsometry show the same tendency of increasing roughness with increased deposition temperature

    To assess the association of polymorphisms of N-acyl-phosphatidylethanolamine-phospholipase D (DAPE-PLD) and fatty acid amide hydrolase (FAAH) genes, as well as their interaction, with schizophrenia. Polymorphisms of NAPE-PLD rs12540583 and FAAH rs324420, rs2295633, and rs6429600 were determined with PCR - restriction fragment length polymorphism assay and Sanger sequencing. The genotypes of 345 subjects of Han Chinese origin diagnosed with schizophrenia and a 403 controls were compared. The results were analyzed with SPSS 17.0, and the interaction of the two genes was analyzed using a multifactor dimensionality reduction (MDR) method. The frequency of NAPE-PLD rs12540583 polymorphism was significantly different between the two groups under both dominant and additive models (χ2=17.18 vs. χ2=18.94, P<0.0125). The frequencies of AC genotype and C allele of the patient group at rs12540583 were higher than those of the controls, and the interaction of NAPE-PLD and FAAH was associated with schizophrenia. A four-loci model (rs12540583, rs324420, rs2295633 and rs6429600) can best model the interaction between NAPE-PLD and FAAH. The AC genotype and C allele of NAPE-PLD rs12540583 locus are risk factors for schizophrenia, and the interaction between NAPE-PLD rs12540583 and FAAH rs324420, rs2295633 and rs6429600 is associated with schizophrenia.

    In:ZnO (IZO) thin films were deposited on flexible plastic substrates by pulsed laser deposition (PLD) method. The obtained layers present adequate optical and electrical properties competitive with those based on indium tin oxide (ITO). The figure of merit (9 × 10-3 Ω-1) calculated for IZO layers demonstrates that high quality coatings can be prepared by this deposition technique. A thermal annealing (150 °C for 1 h) or an oxygen plasma etching (6 mbar for 10 min.) were applied to the IZO layers to evaluate the influence of these treatments on the properties of the transparent coatings. Using vacuum evaporation, organic heterostructures based on cooper phthalocyanine (CuPc) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) were deposited on the untreated and treated IZO layers. The optical and electrical properties of the heterostructures were investigated by UV-Vis, FTIR and current-voltage ( I- V) measurements. For the heterostructure fabricated on IZO treated in oxygen plasma, an improvement in the current value with at least one order of magnitude was evidenced in the I- V characteristics recorded in dark conditions. Also, an increase in the current value for the heterostructure deposited on untreated IZO layer can be achieved by adding an organic layer such as tris-8-hydroxyquinoline aluminium (Alq3).

    The repair of potentially lethal damage (PLDR) in mammalian cells is expected to be better in quiescent cultures since PLD is supposedly fixed during cycle progression. Plateau phase cultures, therefore, serve as models because of assumed mitotic quiescence. Four established cell lines (V79, CHO, L5178Y and HELA) and one euploid cell strain IMR-90 have been analysed by flow cytometry and electron microscopy to address questions on quiescence in the plateau phase and the effect of holding (induction of quiescence by nutrient privation). In contrast to commonly held views, our results indicate that the quiescent fraction in cultures from transformed cells is exceedingly low (1% or less). Plateau phase cultures of transformed cells are constantly turning over. Euploid cells like the IMR-90 show true quiescence in the plateau phase. Holding causes typical cytopathological changes. These changes have been ultrastructurely characterised. Resistant sub-populations of cells can be selected out under holding-conditions. Such selected cells show completely different radiobiological characteristics, which raise questions on the interpretation of data on PLDR. (orig.)

    Thin film capacitors with a thickness of 200 nm were prepared on SrTiO 3 (1 0 0), (1 1 0) and (1 1 1) single crystal substrates at a temperature of 973 K by pulsed laser deposition (PLD) using a KrF excimer laser in an O 2 -O 3 atmosphere with a gas pressure of 1 Pa using an X7R sintered target. As a result, perovskite BaTiO 3 solid solution films were obtained. In the X7R thin films on (1 0 0) and (1 1 0) SrTiO 3 , only diffraction peaks with strong intensities from BaTiO 3 (1 0 0) and (1 1 0), respectively, were observed. X7R films on SrTiO 3 (1 1 1) were grown epitaxially oriented to the crystal plane direction of the substrate by inserting an initial homoepitaxial SrTiO 3 layer with a thickness of 4 nm. The X7R/SrTiO 3 film capacitors yielded a large volumetric efficiency of 50 μF/mm 3 and a temperature coefficient of capacitance (TCC) of -1.3% to 1.3% which satisfies the EIA standard specifications for X7R

    Full Text Available The range of affordances that a virtual environment offers can provide opportunities for more formal Professional Learning and Development (PLD that has flexibility of choice, time and approach for educators. It was this potential that inspired the design of the Virtual Professional Learning and Development (VPLD program that was instigated in October 2009 by the NZ Ministry of Education, who also funded the project. The findings from the pilot of the VPLD program in 2010 indicated that when professional learning was situated within the practitioner's context, and with complementary, easily-accessible opportunities for sharing of practice within an online Community of Practice, participants demonstrated high levels of engagement as well as changes in their own teaching practice. The VPLD Programme was facilitated and researched again during 2011, building on findings from 2010. Findings to date suggest that the educators developed a sense of self-efficacy that motivated them to trial alternative approaches, and to initiate iterative cycles of trial, error, and improvement.

    While a mother's excessive alcohol consumption during pregnancy is known to have adverse effects on fetal neural development, little is known about the underlying mechanism of these effects. In order to investigate these mechanisms, we investigated the toxic effect of ethanol (ETOH) on neural stem/precursor cell (NSC) proliferation. In cultures of NSCs, phospholipase D (PLD) is activated following stimulation with epidermal growth factor (EGF) and fibroblast growth factor 2 (FGF2). Exposure of NSCs to ETOH suppresses cell proliferation, while it has no effect on cell death. Phosphatidic acid (PA), which is a signaling messenger produced by PLD, reverses ETOH inhibition of NSC proliferation. Blocking the PLD signal by 1-butanol suppresses the proliferation. ETOH-induced suppression of NSC proliferation and the protective effect of PA for ETOH-induced suppression are mediated through extracellular signal-regulated kinase signaling. These results indicate that exposure to ETOH impairs NSC proliferation by altering the PLD signaling pathway

    An effective way to improve the superconducting properties in REBa 2 Cu 3 O y (REBCO) films under a magnetic field is to dope artificial pinning centers (APC). The pinning performance depends on the content of the APC materials. Usually, the optimal APC content is explored by preparing films one at a time from the REBCO target using different APC material content, which is an extremely time-consuming process. The combinatorial-PLD (C-PLD) method allowed us to prepare films that continuously changed in composition across a single substrate. In this study, we used the C-PLD method to prepare BaSnO 3 (BSO)-doped YBCO films. The films were deposited on SrTiO 3 substrate using a fourth-harmonic Nd:YAG laser. From the results of the J c -B curves at 77 K and B//c, the film that contained 3.2 vol.% of BSO exhibited the best pinning performance in this study. We showed that the C-PLD method was efficient for quick screening of the optimal APC content with only one deposition. We also used the C-PLD method to explore new APC materials, and proved that it can quickly evaluate the new APC materials Ba 3 Cu 3 In 4 O 12 and BaTbO 3 .

    Phospholipase D2 (PLD2) overexpression in mammalian cells results in cell transformation. We have hypothesized that this is due to an increase of de novo DNA synthesis. We show here that overexpression of PLD2-WT leads to an increased DNA synthesis, as measured by the expression levels of the proliferation markers PCNA, p27 KIP1 and phospho-histone-3. The enhancing effect was even higher with phosphorylation-deficient PLD2-Y179F and PLD2-Y511F mutants. The mechanism for this did not involve the enzymatic activity of the lipase, but, rather, the presence of the protein tyrosine phosphatase CD45, as silencing with siRNA for CD45 abrogated the effect. The two Y→F mutants had in common a YxN consensus site that, in the phosphorylated counterparts, could be recognized by SH2-bearing proteins, such as Grb2. Even though Y179F and Y511F cannot bind Grb2, they could still find other protein partners, one of which, we have reasoned, could be CD45 itself. Affinity purified PLD2 is indeed activated by Grb2 and deactivated by CD45 in vitro. We concluded that phosphorylated PLD2, aided by Grb2, mediates lipase activity, whereas dephosphorylated PLD2 mediates an induction of cell proliferation, and the specific residues involved in this newly discovered regulation of PLD2 are Y 179 and Y 511 .

    Caseous lymphadenitis (CLA) is a chronic disease responsible for significant economic losses in sheep and goat breeding worldwide. The treatment for this disease is not effective, and an intense vaccination schedule would be the best control strategy. In this study, we evaluated the associations of rCP09720 or rCP01850 proteins from Corynebacterium pseudotuberculosis with recombinant exotoxin phospholipase D (rPLD) as subunit vaccines in mice. Four experimental groups (10 animals each) were immunized with a sterile 0.9% saline solution (G1), rPLD (G2), rPLD + rCP09720 (G3), and rPLD + rCP01850 (G4). The mice received two doses of each vaccine at a 21-day interval and were challenged 21 days after the last immunization. The animals were evaluated daily for 40 days after the challenge, and mortality rate was recorded. The total IgG production level increased significantly in the experimental groups on day 42 after the first vaccination. Similarly, higher levels of specific IgG2a were observed in experimental groups G2, G3, and G4 compared to the IgG1 levels on day 42. G4 showed a significant (p < .05) humoral response against both antigens of the antigenic formulations. The cellular immune response induced by immunization was characterized by a significant (p < .05) production of interferon-γ compared to that in the control, while the concentrations of interleukin (IL)-4 and IL-12 were not significant in any group. A significant increase of tumor necrosis factor was observed only in G4. The survival rates after the challenge were 30% (rPLD), 40% (rPLD + rCP09720), and 50% (rPLD + rCP01850). Thus, the association of rCP01850 with rPLD resulted in the best protection against the challenge with C. pseudotuberculosis and induced a more intense type 1 T-helper cell immune response.

    Increase of production rate and improvement of quality for RE123 coated conductors have been tried. In-plane texturing of MgO was attempted by the IBAD system with the world largest ion source. As a result of optimizing condition in large deposition area, the dramatically high throughput of 1000 m / h was realized to obtain the IBAD-MgO with {Delta}{phi} < 10{sup 0}. Furthermore, simple buffer structure was demonstrated. Well textured CeO{sub 2} layer with {Delta}{phi} of around 4{sup 0} was obtained by directly deposited on IBAD-MgO layer in spite of large lattice mismatch of 28% between CeO{sub 2} and MgO. Several over 100 m buffer substrates with the architecture of / PLD-CeO{sub 2} (60 m / h) / IBAD-MgO (333{approx}1000 m / h) / Y{sub 2}O{sub 3} (500 m / h) / Al{sub 2}O{sub 3} (150 m / h) / Hastelloy / were already prepared. On these production substrates, GdBCO layer was deposited by the large PLD system at high throughput. The 260 m long GdBCO tape with I{sub c} > 600 A except some locations was obtained at the throughput of 15 m / h. In addition to the speed-up, the very high I{sub c} of 1040 A was also achieved by the hot-wall heating PLD system.

    Highlights: • SJTU fabricated 100 m long class CC tapes with over 300 A/cm on RABiTS tapes in 2011. • 100 m long CC tapes with 500 A/cm have been routinely fabricated on IBAD-MgO tapes. • The process optimization for kilometer long coated conductor tapes is underway. - Abstract: In China, the First National Key Project on CC Program started in 2009, which was focused on developing hundred meter long class CC tapes based on PLD/RABiTS processes. In this project, SJTU mainly worked on all of functional layer deposition process development. Northwest Institute for Non-ferrous Metal Research worked on RABiTS tape fabrication. At the end of the project in 2011, SJTU successfully fabricated hundred meter long CC tapes with over 300 A/cm (at 77 K, self field) on RABiTS tapes. To develop high performance CC tapes by PLD/IBAD-MgO processes, a pilot CC fabrication line was set up at Shanghai Superconductor Technology Corporation, Ltd. in 2013. High quality long REBCO coated conductors have been successfully fabricated on flexible polycrystalline metal tapes by PLD plus magnetron sputter and IBAD processes. Under optimized conditions, the IBAD-MgO layers showed pure (0 0 1) orientation and excellent in-plane texture. The in-plane phi-scan rocking curve is 4–6 degrees. AFM observation showed MgO layer had very smooth surface. The RMS is less 1 nm. On the textured MgO layer, sputter deposited single cerium oxide cap-layer showed pure (0 0 1) orientation and excellent in-plane texture of 4–6 degree. Reel-to-reel PLD process with high deposition rate was already scaled up to 100 m/h tape speed. Hundred meters long coated conductor tapes with over 500 A/cm performance have been routinely fabricated. And now, the process optimization for kilometer long coated conductor tapes is underway.

    We have developed long GdBa 2 Cu 3 O 7-X (GdBCO) coated conductors by a multi-plume and multi-turn pulsed laser deposition (MPMT-PLD) method and have successfully fabricated 32 and 60.7 m long GdBCO coated conductors with a high critical current, I c , and high deposition rate. The I c of the 32 and 60.7 m long GdBCO coated conductors were 205 A (J c = 1.36 MA cm -2 ) and 183 A (J c = 1.45 MA cm -2 ), respectively, at 77 K and 0 T. In addition, they exhibited higher I c values in a magnetic field than a YBa 2 Cu 3 O 7-X (YBCO) coated conductor: typically 20 A at 77 K and 3 T while the value for a YBCO coated conductor is 8 A. These high I c values are due to the smaller number of a-axis oriented grains in GdBCO than in YBCO. Furthermore, the speed of production of the GdBCO layer was increased to 10 m h -1 while that of the former YBCO coated conductor was 3.75 m h -1 . The material yield of long GdBCO layers using the MPMT-PLD method was about 26-28%. The high I c of GdBCO in a magnetic field, the high production rate and the high material yield are promising for applications

    Strontium copper oxide (SCO) has been studied as p-type transparent (VIS) conductive oxide material. Also theoretical studies suggested p-type conductivity of the SrCu{sub 2}O{sub 2} composition. SCO thin layers, with thicknesses of 30-2000 nm, were deposited on glass and silicon substrates both by pulsed laser deposition (PLD) and by MOCVD method. The as-grown layers showed high electrical resistance. Due to an annealing process, the resistivity significantly decreased and the layers showed p-type conductivity. Optical transparency measured on samples grown on glass substrates was found about or above 80%, including also thickness dependence. RBS measurements were applied for the determination of the chemical composition profile of the layers. A comparison revealed some specific differences between as-grown and annealed PLD samples. Due to the annealing, the ratio of oxide phases was changed and a vertical inhomogeneity in chemical composition was observed. Our measurements revealed also the influence of the deposition technique and of the substrate.

    Neodymium-iron-boron (NdFeB) is a material with important magnetic properties, mostly used in permanent magnet fabrication. Thin layers of NdFeB are needed for miniaturization in electrical engineering, electronics and for high-tech devices. In this paper we applied pulsed lased deposition (PLD) in vacuum for obtaining thin films of NdFeB from stoichiometric targets. The influence of different buffer layers and of the laser parameters (wavelength and fluence) on the NdFeB structures, composition and magnetic properties have been investigated. The obtained structures were characterized by atomic force microscopy (AFM) and optical microscopy. Vibrating sample magnetometry (VSM) has been performed for specific magnetic characterization

    A sulfur-annealing treatment was investigated to control the sulfur content of epitaxial CuInS{sub 2} films grown on GaAs substrate by PLD. The sulfur-annealing treatment improved the surface roughness and film crystallinity. Photoluminescence measurements obtained using the confocal microspectroscopy demonstrated that the annealed films show band-edge emissions over a very large area. Electron-probe microanalysis measurements indicated that the sulfur content of the annealed films was about 50 at.%, and the content of the emission area was more than 50 at.%. Therefore, the sulfur content of epitaxial CuInS{sub 2} films was successfully controlled by the sulfur-annealing treatment. (copyright 2017 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    We present an analysis of Spitzer secondary eclipse observations of exoplanet WASP-29b. WASP-29b is a Saturn-sized, short-period exoplanet with mass 0.24 ± 0.02 Jupiter masses and radius 0.84 ± 0.06 Jupiter radii (Hellier et al., 2010). We measure eclipse depths and midpoints using our Photometry for Orbits, Eclipses, and Transits (POET) code, which does photometry and light-curve modeling with a BiLinearly Interpolated Subpixel Sensitivity (BLISS) map, and our Zen Eliminates Noise (ZEN) code, which takes POET photometry and applies Pixel-Level Decorrelation (PLD). BLISS creates a physical map of pixel gain variations, and is thereby independent of any astrophysical effects. PLD takes a mathematical approach, using relative variations in pixel values near the target to eliminate position-correlated noise. The results are consistent between the methods, except in one outlier observation where neither model could effectively remove correlated noise in the light curve. Using the eclipse timings, along with previous transit observations and radial velocity data, we further refine the orbit of WASP-29b, and, when excluding the outlier, determine an eccentricity between 0.037 and 0.056. We performed atmospheric retrieval with our Bayesian Atmospheric Radiative Transfer (BART) code but find that, when the outlier is discarded, the planet is consistent with a blackbody, and molecular abundances cannot be constrained. This work is based on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA. This work was supported by NASA Planetary Atmospheres grant NNX12AI69G and NASA Astrophysics Data Analysis Program grant NNX13AF38G.

    We sought to evaluate the feasibility and efficacy of hybrid transapical closure of paravalvar mitral leaks using a new Occlutech PLD occluder in patients with heart failure and/or haemolytic anaemia. Retrospective analysis of clinical and procedural data was undertaken for patients who had attempted closure of paravalvar mitral leaks via a hybrid transapical approach with the Occlutech PLD occluder. Eight patients (four males, median age 69 years) underwent closure of 10 mitral paravalvar leaks using eight Occlutech PLD occluders and two AMPLATZER Vascular Plugs (AVP II). Successful deployment, with significant reduction of the paravalvar leak was achieved in seven patients with short procedure (median 131 min) and fluoroscopy times (median 22 min). One patient had mechanical interference with prosthetic valve function, requiring surgery. Another patient with a high EuroSCORE (48.8%) died of multi-organ failure two days after the procedure. Clinical improvement in either heart failure or haemolysis was seen in all discharged patients. In our series of patients with challenging anatomy, the Occlutech PLD occluders performed well when implanted via a hybrid transapical approach. Further work is needed to assess this methodology fully for a wider population and to assess other deployment approaches for this promising new occluder.

    The aim of this study was to evaluate the survival of mice inoculated with M. bovis BCG Pasteur recombinant expressing the PLD protein and challenged with a C. pseudotuberculosis virulent strain. Four groups were immunized with a sterile 0.9% saline solution (G1), 10 6  CFU of M. bovis BCG Pasteur (G2), 10 6  CFU of M. bovis BCG/pld (G3) or 10 6  CFU of M. bovis BCG/pld with a booster with rPLD (G4) and challenged with 10 4 CFU of C. pseudotuberculosis MIC-6 strain. The highest survival rate of 88% was observed in G4, followed by 77% in G3 and 66% in G2. A significant statistical difference was observed in the levels of cytokines IFN-γ and IL-10 in vaccinated groups (G3 and G4) when compared with the control group (G1) (p < 0.05). The results seem promising as the recombinant vaccine elicited a cellular immune response and provided significant survival after a high virulent challenge. Copyright © 2018 Elsevier Ltd.

  8. Effective instruction for English learners.

    Calderón, Margarita; Slavin, Robert; Sánchez, Marta

    2011-01-01

    The fastest-growing student population in U.S. schools today is children of immigrants, half of whom do not speak English fluently and are thus labeled English learners. Although the federal government requires school districts to provide services to English learners, it offers states no policies to follow in identifying, assessing, placing, or instructing them. Margarita Calderón, Robert Slavin, and Marta Sánchez identify the elements of effective instruction and review a variety of successful program models. During 2007-08, more than 5.3 million English learners made up 10.6 percent of the nation's K-12 public school enrollment. Wide and persistent achievement disparities between these English learners and English-proficient students show clearly, say the authors, that schools must address the language, literacy, and academic needs of English learners more effectively. Researchers have fiercely debated the merits of bilingual and English-only reading instruction. In elementary schools, English learners commonly receive thirty minutes of English as a Second Language (ESL) instruction but attend general education classes for the rest of the day, usually with teachers who are unprepared to teach them. Though English learners have strikingly diverse levels of skills, in high school they are typically lumped together, with one teacher to address their widely varying needs. These in-school factors contribute to the achievement disparities. Based on the studies presented here, Calderón, Slavin, and Sánchez assert that the quality of instruction is what matters most in educating English learners. They highlight comprehensive reform models, as well as individual components of these models: school structures and leadership; language and literacy instruction; integration of language, literacy, and content instruction in secondary schools; cooperative learning; professional development; parent and family support teams; tutoring; and monitoring implementation and outcomes

    The method of growing thin films PLD, is widely used in applications and possesses great potential in thin YBa 2 Cu 3 O 7-δ films production with outstanding physical properties. However, it is limited in nano and micro technology due to the presence of particles on the surface of the films. This article describes some causes that create these particles. YBa 2 Cu 3 O 7-δ films have been grown on electrolytic copper used as a variable model the distance target-substrate. The effects are studied through Scanning Electronic Microscopy. It is observed particles with a large variety of shapes and distributions. The results show that ranging the target-substrate distance, the superficial morphology is modified. An evidence of it, is that the evaporation of d B-S = 7 cm, is more coherent that d B-S = 3 cm. Therefore, exist a relation between the morphology and the parameters of growing. Also affect, the structural change that exists among the substrate and the film formation, the substrate preparation and it must not be monocrystalline, these factors define a kinetic and a mechanism of growing that promotes a heterogeneous nucleation.

    Highlights: • Nanostructured Pt-CeO{sub 2} thin catalyst films were grown on plasma etched and non-etched carbon substrates by pulsed laser deposition. • The surface composition of the nanostructured Pt-CeO{sub 2} films was investigated by surface analysis techniques. • The effect of film roughening was separated from the effect of platinum-ceria atomic interactions. - Abstract: The composition of nanostructured Pt-CeO{sub 2} films on graphite substrates prepared by pulsed laser deposition has been investigated by means of hard X-ray photoelectron spectroscopy, scanning electron microscopy, high resolution transmission electron microscopy, and atomic force microscopy. The influence of morphology of the graphite substrates was investigated with respect to the relative concentrations of ionic and metallic Pt species in the films. It was found that the degree of Pt{sup 2+} enrichment is directly related to the surface morphology of graphite substrates. In particular, the deposition of Pt-CeO{sub 2} films on rough graphite substrate etched in oxygen plasma yielded nanostructured Pt-CeO{sub 2} catalyst films with high surface area and high Pt{sup 2+}/Pt{sup 0} ratio. The presented results demonstrate that PLD is a suitable method for the preparation of thin Pt-CeO{sub 2} catalyst films for fuel cell applications.

    Full Text Available International and national mathematics studies have revealed the poor mathematics skills of South African learners. An essential tool that can be used to improve learners' mathematical skills is for educators to use effective feedback. Our purpose in this study was to elicit learners' understanding and expectations of teacher assessment feedback. The study was conducted with five Grade 9 mathematics learners. Data were generated from one group interview, seven journal entries by each learner, video-taped classroom observations and researcher field notes. The study revealed that the learners have insightful perceptions of the concept of educator feedback. While some learners viewed educator feedback as a tool to probe their understanding, others viewed it as a mechanism to get the educator's point of view. A significant finding of the study was that learners viewed educator assessment feedback as instrumental in building or breaking their self-confidence.

    Full Text Available An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to independent licensure has received little research attention. Licensure timing is likely to be related to “push” and “pull” factors which may encourage or inhibit the process. To examine this question, we recruited a sample of 90 novice drivers (49 females and 41 males, average age of 15.6 years soon after they obtained a learner permit and instrumented their vehicles to collect a range of driving data. Participants completed a series of surveys at recruitment related to factors that may influence licensure timing. Two distinct findings emerged from the time-to-event analysis that tested these push and pull factors in relation to licensure timing. The first can be conceptualized as teens’ motivation to drive (push, reflected in a younger age when obtaining a learner permit and extensive pre-permit driving experience. The second finding was teens’ perceptions of their parents’ knowledge of their activities (pull; a proxy for a parents’ attentiveness to their teens’ lives. Teens who reported higher levels of their parents’ knowledge of their activities took longer to advance to independent driving. These findings suggest time-to-licensure may be related to teens’ internal motivation to drive, and the ability of parents to facilitate or impede early licensure.

  16. Improving Learner Handovers in Medical Education.

    2017-07-01

    Multiple studies have demonstrated that the information included in the Medical Student Performance Evaluation fails to reliably predict medical students' future performance. This faulty transfer of information can lead to harm when poorly prepared students fail out of residency or, worse, are shuttled through the medical education system without an honest accounting of their performance. Such poor learner handovers likely arise from two root causes: (1) the absence of agreed-on outcomes of training and/or accepted assessments of those outcomes, and (2) the lack of standardized ways to communicate the results of those assessments. To improve the current learner handover situation, an authentic, shared mental model of competency is needed; high-quality tools to assess that competency must be developed and tested; and transparent, reliable, and safe ways to communicate this information must be created.To achieve these goals, the authors propose using a learner handover process modeled after a patient handover process. The CLASS model includes a description of the learner's Competency attainment, a summary of the Learner's performance, an Action list and statement of Situational awareness, and Synthesis by the receiving program. This model also includes coaching oriented towards improvement along the continuum of education and care. Just as studies have evaluated patient handover models using metrics that matter most to patients, studies must evaluate this learner handover model using metrics that matter most to providers, patients, and learners.

    CoPd alloy thin films with different thicknesses and Co/Pd ratios have been deposited on Si (100) substrate by pulsed laser deposition (PLD). The magnetic properties were investigated by using the magneto-optical Kerr effect (MOKE) in both longitudinal and polar geometries. The results show that the films with thickness in the range of 6-24 nm, deposited at a low substrate temperature of 200 °C, are mostly magnetized in the plane of film. Higher deposition temperature forces the magnetic easy axis to orient in the perpendicular direction of the films.

  19. Inhibition of X-ray-induced potentially lethal damage (PLD) repair in aerobic plateau-phase Chinese hamster cells by misonidazole

    1984-01-01

    The effect of the 2-nitroimidazole radiosensitizer misonidazole (MISO) and the hydrophilic analog SR-2508 on the repair of X-ray-induced potentially lethal damage (PLD) was studied in plateau-phase Chinese Hamster ovary (HA-1) cells. It was found that although MISO does not radiosensitize aerobic cells, it inhibits the repair of PLD. However, under hypoxic conditions, MISO has no effect on PLD repair. The major portion of the inhibition of PLD repair in aerobic cells requires the presence of MISO only during irradiation; little or no additional inhibition occurs when MISO is present during the postirradiation repair period. Also, treatment of aerobic cells with 5 mM MISO for either 5 or 30 min prior to irradiation is equally inhibitory. This suggests that the presence of MISO in some way modifies the initial lesion under aerobic conditions since it does not increase cell killing as determined by immediate plating but inhibits subsequent repair. The inhibition is concentration dependent; 0.5 mM MISO inhibits PLD repair by one-half while 5-10 mM totally inhibits the repair measured 6 hr postirradiation. This phenomenon suggests that radiosensitization of tissue in vivo by MISO and other 2-nitroimidazoles may not be unequivocal proof of the presence of hypoxic cells

    Treatment of human pulmonary artery smooth muscle cells with ET-1 stimulated PLD and NADPH oxidase activities, which were inhibited upon pretreatment with bosentan (ET-1 receptor antagonist), FIPI (PLD inhibitor), apocynin (NADPH oxidase inhibitor) and EGCG & ECG (catechins having galloyl group), but not EGC & EC (catechins devoid of galloyl group). Herein, we determined the probable mechanism by which the galloyl group containing catechins inhibit ET-1 induced stimulation of PLD activity by molecular docking analyses based on our biochemical studies. ET-1 induced stimulation of PLD activity was inhibited by SecinH3 (inhibitor of cytohesin). Arf-6 and cytohesin-1 were associated in the cell membrane, which was not inhibited by the catechins during ET-1 treatment to the cells. However, EGCG and ECG inhibited binding of GTPγS with Arf-6 even in presence of cytohesin-1. The molecular docking analyses revealed that the galloyl group containing catechins (EGCG/ECG) with cytohesin1-Arf6GDP, but not the non-galloyl-containing catechins (EGC and EC), prevents GDP/GTP exchange in Arf-6 which seems to be an important mechanism for inhibition of ET-1 induced activation of PLD and subsequently increase in NADPH oxidase activities.

    The regulation of PLD2 activation is poorly understood at present. Transient transfection of COS-7 with a mycPLD2 construct results in elevated levels of PLD2 enzymatic activity and tyrosyl phosphorylation. To investigate whether this phosphorylation affects PLD2 enzymatic activity, anti-myc immunoprecipitates were treated with recombinant protein tyrosine phosphatase PTP1B. Surprisingly, lipase activity and PY levels both increased over a range of PTP1B concentrations. These increases occurred in parallel to a measurable PTP1B-associated phosphatase activity. Inhibitor studies demonstrated that an EGF-receptor type kinase is involved in phosphorylation. In a COS-7 cell line created in the laboratory that stably expressed myc-PLD2, PTP1B induced a robust (>6-fold) augmentation of myc-PLD2 phosphotyrosine content. The addition of growth factor receptor-bound protein 2 (Grb2) to cell extracts also elevated PY levels of myc-PLD (>10-fold). Systematic co-immunoprecipitation-immunoblotting experiments pointed at a physical association between PLD2, Grb2 and PTP1B in both physiological conditions and in overexpressed cells. This is the first report of a demonstration of the mammalian isoform PLD2 existing in a ternary complex with a protein tyrosine phosphatase, PTP1b, and the docking protein Grb2 which greatly enhances tyrosyl phosphorylation of the lipase.

    Full Text Available The critical discussions and matters in enhancing students’ learning performance, knowledge, and language proficiency have received a remarkable degree of attention in educational contexts. This study was undertaken to encourage learners to build the required competence in the foreign language by utilizing learning strategies so that they could become autonomous learners. Language learners' learning difficulties while learning a foreign language were identified in this study. With regard to problems which language learners faced in learning a foreign language, the teachers are able to recognize and to utilize appropriate language learning strategies in order to develop autonomy in learners who conceptualize and use those strategies in the foreign language. The research design adopted for the present study was survey method. The data for the study were collected with the use of a questionnaire. This questionnaire was administered to a total of 60 EFL learners who were selected from a university in Iran. It was used to assess learners’ awareness and perceived use of strategies and to provide data on their best utilized strategies. Results have been driven through statistical analysis. The analyzed data reveal the students’ styles and assist teachers to take part in shifting the strategies and heighten language learners' autonomy. The findings support the claim that knowing and making language learners aware of the most appropriate strategy would assist learners to improve their autonomy and to enhance their learning.

  4. Adenoviral gene transfer of PLD1-D4 enhances insulin sensitivity in mice by disrupting phospholipase D1 interaction with PED/PEA-15.

    Directory of Open Access Journals (Sweden)

    Angela Cassese

    Full Text Available Over-expression of phosphoprotein enriched in diabetes/phosphoprotein enriched in astrocytes (PED/PEA-15 causes insulin resistance by interacting with the D4 domain of phospholipase D1 (PLD1. Indeed, the disruption of this association restores insulin sensitivity in cultured cells over-expressing PED/PEA-15. Whether the displacement of PLD1 from PED/PEA-15 improves insulin sensitivity in vivo has not been explored yet. In this work we show that treatment with a recombinant adenoviral vector containing the human D4 cDNA (Ad-D4 restores normal glucose homeostasis in transgenic mice overexpressing PED/PEA-15 (Tg ped/pea-15 by improving both insulin sensitivity and secretion. In skeletal muscle of these mice, D4 over-expression inhibited PED/PEA-15-PLD1 interaction, decreased Protein Kinase C alpha activation and restored insulin induced Protein Kinase C zeta activation, leading to amelioration of insulin-dependent glucose uptake. Interestingly, Ad-D4 administration improved insulin sensitivity also in high-fat diet treated obese C57Bl/6 mice. We conclude that PED/PEA-15-PLD1 interaction may represent a novel target for interventions aiming at improving glucose tolerance.

  5. Coronin 1B regulates S1P-induced human lung endothelial cell chemotaxis: role of PLD2, protein kinase C and Rac1 signal transduction.

    Directory of Open Access Journals (Sweden)

    Full Text Available Coronins are a highly conserved family of actin binding proteins that regulate actin-dependent processes such as cell motility and endocytosis. We found that treatment of human pulmonary artery endothelial cells (HPAECs with the bioactive lipid, sphingosine-1-phosphate (S1P rapidly stimulates coronin 1B translocation to lamellipodia at the cell leading edge, which is required for S1P-induced chemotaxis. Further, S1P-induced chemotaxis of HPAECs was attenuated by pretreatment with small interfering RNA (siRNA targeting coronin 1B (∼36%, PLD2 (∼45% or Rac1 (∼50% compared to scrambled siRNA controls. Down regulation PLD2 expression by siRNA also attenuated S1P-induced coronin 1B translocation to the leading edge of the cell periphery while PLD1 silencing had no effect. Also, S1P-induced coronin 1B redistribution to cell periphery and chemotaxis was attenuated by inhibition of Rac1 and over-expression of dominant negative PKC δ, ε and ζ isoforms in HPAECs. These results demonstrate that S1P activation of PLD2, PKC and Rac1 is part of the signaling cascade that regulates coronin 1B translocation to the cell periphery and the ensuing cell chemotaxis.

    The pulsed laser deposition (PLD) substrate temperature and post-annealing temperature are effective methods to control the film optical and structural properties. The structure, morphology and optical properties of the deposited and post-annealed PLD ZnO:Zn films were studied. The films were deposited at different substrate temperatures of 50 °C, 200 °C and 400 °C. The films deposited at the substrate temperature of 50 °C and 200 °C were post-annealed in air at 400 °C and 600 °C for two hours. The films all had a highly preferential orientation with the hexagonal c-axis perpendicular to the substrate surface. The stress was found to be compressive stress with values -3.289 GPa, -4.864 GPa and -4.425 GPa for the film deposited at 50 °C, 200 °C and 400 °C, respectively. After post-annealing treatments, the stress of the films was almost completely released and stress-free films were obtained. The crystallite sizes were 19 nm, 25 nm and 39 nm, while the average particles sizes were 95 nm, 85 nm and 129 nm for the film deposited at 50 °C, 200 °C and 400 °C respectively. The crystallite sizes and particles sizes seemed to increase with the increase in the substrate temperature. Contrary to this, the change in crystallite sizes were inversely proportional to the particles size when increasing the post-annealing temperatures. Deconvoluted X-ray photoelectron spectroscopy peaks of the O1s binding energy region revealed that the films deposited at different substrate temperatures contained oxygen-related defects. Photoluminescence studies revealed that the films all emitted ultra-violet emission around 379 nm. The film deposited at 50 °C emitted a broad green emission centered at ∼524 nm. By increasing the substrate temperature up to 200 °C and 400 °C a new orange emission around 621 nm and 634 nm as well as a weak emission around 416 nm and 500 nm were observed, respectively. After post-annealing treatments, new bands over the visible region (blue, green

    2017-05-01

    Full Text Available Increase in Nd contents of a PLD-made isotropic Nd-Fe-B thick-film magnet enabled us to enhance the thickness of the film magnet deposited on a Si substrate because the linear expansion coefficient of Nd is an intermediate value between Nd2Fe14B and Si. The large amount of Nd, however, degraded the residual magnetic polarization and (BHmax. In the study, we reduced the Nd contents of each Nd-Fe-B film by inserting a Nd or a Nd-rich Nd-Fe-B buffer layer between a Nd-Fe-B film and a Si substrate in order to suppress the mechanical destruction together with the improvement in magnetic properties. It was found that the mechanical property of a Nd-Fe-B film comprising the Nd-Fe-B buffer layer in the thickness range from 10 to 60 μm was superior than that of a sample with the Nd buffer layer. Resultantly, an average (BHmax value of Nd-Fe-B films with each Nd-Fe-B buffer layer deposited on Si substrates could be enhanced by approximately 15 kJ/m3 compared to that of non-buffer-layered films.

  17. Cue generation: How learners flexibly support future retrieval.

    Tullis, Jonathan G; Benjamin, Aaron S

    2015-08-01

    The successful use of memory requires us to be sensitive to the cues that will be present during retrieval. In many situations, we have some control over the external cues that we will encounter. For instance, learners create shopping lists at home to help remember what items to later buy at the grocery store, and they generate computer file names to help remember the contents of those files. Generating cues in the service of later cognitive goals is a complex task that lies at the intersection of metacognition, communication, and memory. In this series of experiments, we investigated how and how well learners generate external mnemonic cues. Across 5 experiments, learners generated a cue for each target word in a to-be-remembered list and received these cues during a later cued recall test. Learners flexibly generated cues in response to different instructional demands and study list compositions. When generating mnemonic cues, as compared to descriptions of target items, learners produced cues that were more distinct than mere descriptions and consequently elicited greater cued recall performance than those descriptions. When learners were aware of competing targets in the study list, they generated mnemonic cues with smaller cue-to-target associative strength but that were even more distinct. These adaptations led to fewer confusions among competing targets and enhanced cued recall performance. These results provide another example of the metacognitively sophisticated tactics that learners use to effectively support future retrieval.

    In order to fabricate YBa2Cu3O7-x (YBCO) coated conductors with high critical current density Jc in magnetic fields, we fabricated YBCO coated conductors with artificial pinning centers by the pulsed laser deposition (PLD) method on a self epitaxial PLD-CeO2 layer and ion-beam assisted deposition (IBAD)-Gd2Zr2O7 (GZO) buffered Hastelloy tape. Artificial pinning centers were introduced by the PLD deposition using the yttria-stabilized zirconia (YSZ) oxide target (nano-dot method) and YBCO target including YSZ particles (mixed target method). In the experiments using YSZ oxide target, YSZ nano-dots were observed. They were approximately 15 nm in height and 10 nm to 70 nm in diameter. We found that the density of nano-dots was controlled by the number of laser pulses. These samples exhibited higher Jc than YBCO films in magnetic fields. Furthermore, a similar improvement of Jc was observed in the experiments using YBCO target including YSZ particles. TEM observation revealed that columnar nano-structure made of BaZrO3 was formed during YBCO deposition and it was effective for pinning. We call this new epitaxial nano-structure 'bamboo structure' from its anisotropic growth and morphology

    SRL-Nagoya Coated Conductor Center (NCCC) have succeeded in fabricating stably long coated conductor using ion-beam assisted deposition (IBAD) and pulsed laser deposition (PLD) methods. Reel-to-reel PLD equipment with a multi-plume and multi-turn deposition system (MPMT PLD) resulted in a long coated conductor with a high critical current, I c , of 245 A and length of 212.6 m. I c x L (length) reached the record of 52,087 A m. At the same time, the effort to enhance I c and J c in a magnetic filed are also carried out using artificial pinning center and RE element: YSZ mixed Y123 target brought about a high J c especially in the magnetic field parallel to the c-axis. This was attributed to a columnar structure of the 'bamboo structure' (BaZrO 3 /Y123 layer-stacked structure) in Y123 + YSZ sample. Gd123 was also found to be effective for enhancing pinning properties, which was considered to be due to the native stacking faults in the 123 structure. The combination of Gd element and YSZ introduction were also studied and clearly demonstrated the improvement of the anisotropy of J c for a magnetic field angle

    High-quality GaN epitaxial films have been grown on Si substrates with Al buffer layer by the combination of molecular beam epitaxy (MBE) and pulsed laser deposition (PLD) technologies. MBE is used to grow Al buffer layer at first, and then PLD is deployed to grow GaN epitaxial films on the Al buffer layer. The surface morphology, crystalline quality, and interfacial property of as-grown GaN epitaxial films on Si substrates are studied systematically. The as-grown ~300 nm-thick GaN epitaxial films grown at 850 °C with ~30 nm-thick Al buffer layer on Si substrates show high crystalline quality with the full-width at half-maximum (FWHM) for GaN(0002) and GaN(102) X-ray rocking curves of 0.45° and 0.61°, respectively; very flat GaN surface with the root-mean-square surface roughness of 2.5 nm; as well as the sharp and abrupt GaN/AlGaN/Al/Si hetero-interfaces. Furthermore, the corresponding growth mechanism of GaN epitaxial films grown on Si substrates with Al buffer layer by the combination of MBE and PLD is hence studied in depth. This work provides a novel and simple approach for the epitaxial growth of high-quality GaN epitaxial films on Si substrates.

    Pulsed Laser Deposition (PLD) is an ablation technique for thin film preparation of many materials. The film properties can be well controlled by the process parameters. Therefore, in many cases a given material can be deposited with different properties by changing one or more process parameters. In this thesis thin films of gallium oxide, gallium nitride and barium zirconate were deposited with a large variation in structure and stoichiometry by means of Pulsed Laser Deposition. The characterization of the film crystallinity, phase purity and short range structural order was completed by means of X-ray diffraction and X-ray absorption spectroscopy. The stoichiometry was investigated using electron probe microanalysis. For analyzing the correlation between the structure and stoichiometry with the optical and electrical properties, optical absorption and electrical conductivity measurements were carried out. The investigation of all three material systems showed that very unique properties can be realized when combining an amorphous structure and a non-stoichiometric composition. For example, in amorphous and oxygen deficient gallium oxide an insulator-metal-transition can be induced by partial crystallization of the as prepared phase accomplished by annealing at about 400 C in argon atmosphere (as shown in literature). Furthermore, amorphous and highly non-stoichiometric barium zirconate has the ability to split water molecules to hydrogen and oxygen at room temperature. A detailed analysis of both phenomena has been performed by means of photoemission and transmission electron microscopy in the case of gallium oxide and via X-ray absorption spectroscopy and gas chromatography in the case of barium zirconate.

  6. Localization of peroxisome proliferator-activated receptor alpha (PPARα) and N-acyl phosphatidylethanolamine phospholipase D (NAPE-PLD) in cells expressing the Ca2+-binding proteins calbindin, calretinin, and parvalbumin in the adult rat hippocampus

    The N-acylethanolamines (NAEs), oleoylethanolamide (OEA) and palmithylethanolamide (PEA) are known to be endogenous ligands of PPARα receptors, and their presence requires the activation of a specific phospholipase D (NAPE-PLD) associated with intracellular Ca2+ fluxes. Thus, the identification of a specific population of NAPE-PLD/PPARα-containing neurons that express selective Ca2+-binding proteins (CaBPs) may provide a neuroanatomical basis to better understand the PPARα system in the brain. For this purpose, we used double-label immunofluorescence and confocal laser scanning microscopy for the characterization of the co-existence of NAPE-PLD/PPARα and the CaBPs calbindin D28k, calretinin and parvalbumin in the rat hippocampus. PPARα expression was specifically localized in the cell nucleus and, occasionally, in the cytoplasm of the principal cells (dentate granular and CA pyramidal cells) and some non-principal cells of the hippocampus. PPARα was expressed in the calbindin-containing cells of the granular cell layer of the dentate gyrus (DG) and the SP of CA1. These principal PPARα+/calbindin+ cells were closely surrounded by NAPE-PLD+ fiber varicosities. No pyramidal PPARα+/calbindin+ cells were detected in CA3. Most cells containing parvalbumin expressed both NAPE-PLD and PPARα in the principal layers of the DG and CA1/3. A small number of cells containing PPARα and calretinin was found along the hippocampus. Scattered NAPE-PLD+/calretinin+ cells were specifically detected in CA3. NAPE-PLD+ puncta surrounded the calretinin+ cells localized in the principal cells of the DG and CA1. The identification of the hippocampal subpopulations of NAPE-PLD/PPARα-containing neurons that express selective CaBPs should be considered when analyzing the role of NAEs/PPARα-signaling system in the regulation of hippocampal functions.

    Highlights: • Thermoelectric PbTe thin films, with increasing Ag percentage, were deposited by PLD. • Almost stoichiometric PbTe (Ag doped) films were grown, as verified by XPS analysis. • GI-XRD established the formation of cubic PbTe, with nano-metric structure (∼35 nm). • Surface resistivity shows an increase in conductivity, with increasing Ag doping. • From Seebeck values and XPS depth analysis, 10% Ag seems to be the solubility limit. - Abstract: It has been evaluated the ability of ArF pulsed laser ablation to grow nano-crystalline thin films of high temperature PbTe thermoelectric material, and to obtain a uniform and controlled Ag blending, through the entire thickness of the film, using a multi-target system in vacuum. The substrate used was a mirror polished technical alumina slab. The increasing atomic percentage of Ag effect on physical–chemical and electronic properties was evaluated in the range 300–575 K. The stoichiometry and the distribution of the Ag component, over the whole thickness of the samples deposited, have been studied by XPS (X-ray photoelectron spectroscopy) and corresponding depth profiles. The crystallographic structure of the film was analyzed by grazing incidence X-ray diffraction (GI-XRD) system. Scherrer analysis for crystallite size shows the presence of nano-structures, of the order of 30–35 nm. Electrical resistivity of the samples, studied by the four point probe method, as a function of increasing Ag content, shows a typical semi-conductor behavior. From conductivity values, carrier concentration and Seebeck parameter determination, the power factor of deposited films was calculated. Both XPS, Hall mobility and Seebeck analysis seem to indicate a limit value to the Ag solubility of the order of 5%, for thin films of ∼200 nm thickness, deposited at 350 °C. These data resulted to be comparable to theoretical evaluation for thin films but order of magnitude lower than the corresponding bulk materials.

  3. Engaging learners in STEM education

    2017-04-01

    Full Text Available In this manuscript we focus on how to develop STEM learning environments, and how STEM can be implemented in K-12 schools. We focus on the following question: “How can we support students in building a deep, integrated knowledge of STEM so that they have the practical knowledge and problem solving skills necessary to live in and improve the world?” We also discuss criteria for evaluating STEM learning environments and the challenges teachers face in implementing STEM. We define STEM as the integration of science, engineering, technology, and mathematics to focus on solving pressing individual and societal problems. Engaging students in STEM also means engaging learners in the design process. Design is integral to student thinking in the STEM world. The design process is very non-linear and iterative in its nature but requires clearly articulating and identifying the design problem, researching what is known about the problem, generating potential solutions, developing prototype designs (artifacts that demonstrate solutions, and sharing and receiving feedback. With the integration of design, STEM education has the potential to support students in learning big ideas in science and engineering, as well as important scientific and engineering practices, and support students in developing important motivational outcomes such as ownership, agency and efficacy. Moreover, students who engage in STEM learning environments will also develop 21st century capabilities such as problem solving, communication, and collaboration skills.

    InGaZnO (IGZO) is a promising semiconductor material for thin-film transistors (TFTs) used in DC and RF switching applications, especially since it can be grown at low temperatures on a wide variety of substrates. Enhancement-mode TFTs based on IGZO thin films grown by pulsed laser deposition (PLD) have been recently fabricated and these transistors show excellent performance; however, compositional variations and defects can adversely affect film quality, especially in regard to electrical properties. In this study, we use thermally stimulated current (TSC) spectroscopy to characterize the electrical properties and the deep traps in PLD-grown IGZO thin films. It was found that the as-grown sample has a DC activation energy of 0.62 eV, and two major traps with activation energies at 0.16-0.26 eV and at 0.90 eV. However, a strong persistent photocurrent (PPC) sometimes exists in the as-grown sample, so we carry out post-growth annealing in an attempt to mitigate the effect. It was found that annealing in argon increases the conduction, produces more PPC and also makes more traps observable. Annealing in air makes the film more resistive, and removes PPC and all traps but one. This work demonstrates that current-based trap emission, such as that associated with the TSC, can effectively reveal electronic defects in highlyresistive semiconductor materials, especially those are not amenable to capacitance-based techniques, such as deeplevel transient spectroscopy (DLTS).

    Cordycepin (3'-deoxyadenosine, 3 - dA) is an RNA antimetabolite and a radiosensitizer in cultured mammalian cells. In the present paper, the effects of 3'-dA on γ-ray-induced lethality and 6-thioguanine (6TG)-resistant mutations in cultured Chinese hamster V79 cells were examined. 3'-dA had the effect of sensitizing the lethality induced by γ-rays. The potentially lethal damage (PLD) repair produced by post-incubation cells in Hanks' solution after γ-irradiation was almost completely suppressed by 5x10 -5 M 3'-dA. When cells were irradiated with 10 Gy γ-rays and incubated with 3'-dA for 5 h, the frequency of 6TG-resistant mutations induced by γ-rays decreased to 1/6 of that of the irradiated cells incubated without 3'-dA. The decrease in the frequency of γ-ray-induced mutations was dependent on the length of incubation time with 3'-dA. It is suggested that the inhibition of PLD repair by 3'-dA may be that of error-prone repair. (author). 26 refs.; 5 figs

    2014-02-01

    Although many medical learners and teachers are using mobile technologies within medical education, there has been little evidence presented describing how they use mobile devices across a whole curriculum. The Northern Ontario School of Medicine (NOSM) introduced a new mobile device program in 2010. Incoming undergraduate medical learners received a laptop and an iPad and learners entering year three of the four-year program received a laptop and an iPhone. A survey was sent to all learners to gather information on their use of and attitudes toward these devices. A combination of quantitative and qualitative methods was used to analyze the data and to generate a series of themes that synthesized student behaviors, perceptions and attitudes. Context and learner autonomy were found to be important factors with learners using multiple devices for different purposes and adopting strategic approaches to learning using these devices. The expectation that school-issued devices would be regularly and enthusiastically used to replace more traditional study media was not reflected in practice. Learners' approaches to using mobile devices are heterogeneous as is the extent to which they use them. Learners adapt their use of mobile devices to the learning cultures and contexts they find themselves in.

  11. PED/PEA-15 inhibits hydrogen peroxide-induced apoptosis in Ins-1E pancreatic beta-cells via PLD-1.

    Directory of Open Access Journals (Sweden)

    Francesca Fiory

    Full Text Available The small scaffold protein PED/PEA-15 is involved in several different physiologic and pathologic processes, such as cell proliferation and survival, diabetes and cancer. PED/PEA-15 exerts an anti-apoptotic function due to its ability to interfere with both extrinsic and intrinsic apoptotic pathways in different cell types. Recent evidence shows that mice overexpressing PED/PEA-15 present larger pancreatic islets and increased beta-cells mass. In the present work we investigated PED/PEA-15 role in hydrogen peroxide-induced apoptosis in Ins-1E beta-cells. In pancreatic islets isolated from Tg(PED/PEA-15 mice hydrogen peroxide-induced DNA fragmentation was lower compared to WT islets. TUNEL analysis showed that PED/PEA-15 overexpression increases the viability of Ins-1E beta-cells and enhances their resistance to apoptosis induced by hydrogen peroxide exposure. The activity of caspase-3 and the cleavage of PARP-1 were markedly reduced in Ins-1E cells overexpressing PED/PEA-15 (Ins-1E(PED/PEA-15. In parallel, we observed a decrease of the mRNA levels of pro-apoptotic genes Bcl-xS and Bad. In contrast, the expression of the anti-apoptotic gene Bcl-xL was enhanced. Accordingly, DNA fragmentation was higher in control cells compared to Ins-1E(PED/PEA-15 cells. Interestingly, the preincubation with propranolol, an inhibitor of the pathway of PLD-1, a known interactor of PED/PEA-15, responsible for its deleterious effects on glucose tolerance, abolishes the antiapoptotic effects of PED/PEA-15 overexpression in Ins-1E beta-cells. The same results have been obtained by inhibiting PED/PEA-15 interaction with PLD-1 in Ins-1E(PED/PEA-15. These results show that PED/PEA-15 overexpression is sufficient to block hydrogen peroxide-induced apoptosis in Ins-1E cells through a PLD-1 mediated mechanism.

The subjects are put in a relatively real English referential communication setting and the analyses of the research data show that Chinese English learners, when encountering problems in foreign language (FL) communication, are characterized by the frequent use of substitution, approximation, circumlocution, literal translation, exemplification, word-coinage, repetition, and the infrequent use of cultural-knowledge and paralinguistic CSs. The rare use of paralinguistic strategies is found to be typical of Chinese English learners. The high frequency of literal translation, one first language (L1)-based strategy in our study sample, suggests that FL learners' use of L1-based CSs may depend more upon the developmental stage of their target language than the typology distance between L1 and the target language. The frequency of repetition reveals one fact that the Chinese English learners lack variety and flexibility in their use of CSs. Based on these findings, it was indicated that learners' use of CSs is influenced by a variety of factors, among which the development stage of their interlanguage and their cultural background are identified as two important factors. Some implications are finally suggested for the English foreign language teaching practice in China.

    A pre-annealing atmospheric pulsed laser exposure was applied to decrease the phase transition (from chemically disordered A1 phase to chemically ordered L1 0 phase) temperature of FePt nano-particles on a Si (100) substrate. Different pre-annealing laser energy densities of 0.024 and 0.079 J/cm2 were utilized to expose the pulsed laser deposition (PLD) FePt thin film samples under atmospheric conditions. Subsequently, FePt thin film samples were annealed at different temperatures of 300 and 400 ºC to observe the influence of laser exposure on the phase transition temperature. The phase transition temperature was decreased from conventional 600 ºC to 400 ºC by one shot pre-annealing atmospheric pulsed laser exposure. (author)

    Ferroelectric thin films of Ba{sub 0.7}Sr{sub 0.3}TiO{sub 3} (BST) were deposited on Si/SiO{sub 2}/TiO{sub 2}/Pt (PtSi) substrate by pulsed laser deposition (PLD). Crystalline films with perovskite structure were obtained without post-deposition annealing. Phase purity of the deposited films was confirmed by x-ray diffraction. The lowest value of FWHM obtained for the film deposited at oxygen pressure 5.4×10{sup −4} mbar and substrate temperature 600°C, indicates the high crystallinity of the film. The room temperature dielectric constant at 100 kHz was 85. Butterfly loop, which is the characteristic of ferroelectric materials, was obtained in the regime of −4 to +4V. The leakage current density was nearly 9×10{sup −13} Acm{sup −2}.

    In SRL-Nagoya Coated Conductor Center (NCCC), long buffered substrate tapes and YBCO coated conductors have been successfully fabricated by using ion-beam assisted deposition (IBAD) and pulsed laser deposition (PLD) methods. For the buffered tape, the PLD-CeO2 method, what we call the 'Self-Epitaxial' method, realized the high degree of in-plane texturing around 4 degrees along the length of 220 m. For YBCO deposition, we have recently introduced new reel-to-reel PLD equipment with a multi-plume and multi-turn deposition system (MPMT PLD). This system succeeded in fabricating a long coated conductor with a high critical current, Ic, of 245 A and length of 212 m. Ic xL (length) reached the world record of 51940 Am. Furthermore, the introduction of artificial pinning center and RE 123 materials were also studied for improving flux pinning and enhancing Ic. A new columnar structure of the 'bamboo structure' (BaZrO3/Y123 layer-stacked structure) was found in Y123+YSZ sample. This columnar structure and the stacking faults in Gd123 were found to be effective for enhancing pinning properties. Using these techniques, we have succeeded in increasing Ic at 0 T to 480 A/cm and also enhancing Ic in a magnetic field

It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

    Millennial learners are changing the face of residency education because they place emphasis on technology with new styles and means of learning. While research on the most effective way to teach the millennial learner is lacking, programs should consider incorporating educational theories and multimedia design principles to update the curriculum for these new learners. The purpose of the study is to discuss strategies for updating an emergency medicine (EM) residency program's curriculum to accommodate the modern learner. These 10 tips provide detailed examples and approaches to incorporate technology and learning theories into an EM curriculum to potentially enhance learning and engagement by residents. While it is unclear whether technologies actually promote or enhance learning, millennials use these technologies. Identifying best practice, grounded by theory and active learning principles, may help learners receive quality, high-yield education. Future studies will need to evaluate the efficacy of these techniques to fully delineate best practices.

    Objective: To investigate the changes of serum levels of collagen type IV(IV-C), procollagen type III (PC III), hyaluronic acid (HA), laminin (LN) and prolidase (PLD) and their relationship with hepatic fibrosis in patients with B hepatitis of different types. Methods: Serum levels of IV-C, PC III, HA, LN and PLD were measured with RIA in 39 controls and 103 patients with HBV infection of various types (including acute hepatitis AH n=19, chronic persistent hepatitis CPH n=29, Chronic active hepatitis CAH n=25 and liver cirrhosis LH n=30. Degree of hepatic fibrosis (Grade 0-4) was ascertained with liver biopsy in 35 patients (CAH16, LC19) and correlationship with the corresponding levels of these 5 serum markers was steadied. Results: 1) Serum levels of IV-C, PC III, HA, LN and PLD were significantly higher in patients with CAH and LC than those in other patients and controls (P 0.05). 3) Serum levels of these markers were all positively correlated with the degree of hepatic fibrosis noted in the biopsy specimens obtained from patients with CAH (n=16) and LC (n=19) (r=+0.64 - + 0.89, P<0.01). Conclusion: Serum levels of these markers could reflect the degree of hepatic fibrosis and severity of liver damage; determination of which was of diagnostic and even prognostic value. HA and LN appeared to be better correlated with degree of hepatic fibrosis than the remaining three markers did. (authors)

  4. High Ability and Learner Characteristics

    Full Text Available The outstandingly able learner has been conceptualised, in terms of test and examination performance, as the learner showing superior academic performance which is markedly better than that of peers and in ways regarded as of value by wider society. In Kuwait, such superior examination performance leads to a classification regarded as being ‘gifted’. This study looks at the inter-correlations between performance in various subjects in examinations and then considers how examination performance correlates with measures of working memory capacity, extent of field dependency, extent of divergency and visual-spatial abilities. A very large sample of grade 7 Kuwaiti students (aged ~13 was involved, the sample being selected in such a way that it contained a high proportion of those regarded as ‘gifted’ under the procedures used in Kuwait. While specific learner characteristics have been related to examination performance, this study brings four different characteristics together to gain a picture of the way these characteristics may be seen in those who perform extremely well in examinations. Principal components analysis using varimax rotation, was used to look at the examination data and one factor accounted for 87% of the variance. A consideration of the examination papers led to the conclusion that the national examinations tested only recall-recognition. It was also found that those who performed best in all six subjects tended to be those who are highly divergent and strongly visual-spatial as well as those tending to have higher working memory capacities and being more field independent. The inter-correlations between the various learner characteristics are explained in terms of the way the brain is known to process information. The implications of the findings for assessment and for the way high ability is considered are discussed.

  6. Learner discipline: An Australian perspective

    Directory of Open Access Journals (Sweden)

    D. Stewart

    2004-07-01

    Full Text Available Australian schools by and large are safe schools. Nonetheless discipline problems do exist – including bullying behaviour. For this kind of problem schools should have management policies in place. As traditional behaviour-management practices – including corporal punishment – are largely prohibited in Australian schools, contemporary practices centre on management through supportive school programmes, including appropriate curricula and school-support structures. This article supports the belief that measures such as the exclusion of misbehaving learners should be treated with caution. Measures such as this might not reflect accepted international principles and practices and should only be exercised in the most extreme circumstances. The article also supports the view that it is part of the school’s role to ensure that all learners are aware of the reality that while they have rights, they also have corresponding responsibilities. This awareness is more likely to be achieved in a supportive school culture where each learner is recognised as having unique qualities that can mature and grow in an appropriate learning environment.

    Cu-In-S precursor films were deposited at various substrate temperatures by pulsed laser deposition (PLD). CuIn(S,Se){sub 2} films were prepared by post-annealing the Cu-In-S precursor films in H{sub 2}S and Se atmosphere. CuIn(S,Se){sub 2} solar cells with a device structure of Au/ITO/i-ZnO/CdS/CuIn(S,Se){sub 2}/Mo/soda-lime (SLG) glass were fabricated and characterized. Higher conversion efficiency was obtained for the CuIn(S,Se){sub 2} solar cell with the precursor film deposited at room temperature. The phase and microstructure of the Cu-In-S precursor and the annealed CuIn(S,Se){sub 2} films were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). We found that the quality of the CuIn(S,Se){sub 2} films was strongly affected by the deposition temperature of Cu-In-S precursor films. We discuss the grain growth and sintering in CuIn(S,Se){sub 2} films on the basis of the results of XRD and SEM. The highest conversion efficiency of 6.38% (V{sub oc}= 521 mV, J{sub sc}= 22.6 mA cm{sup -2}, FF = 0.541) was obtained for the CuIn(S,Se){sub 2} solar cell with the precursor film deposited at room temperature and post-annealed at 620 C. The solar cell was analyzed by secondary ion mass spectroscopy (SIMS) and transmission electron microscopy (TEM). (copyright 2017 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Full Text Available We report the findings of a qualitative study embedded in an interpretive paradigm to determine the perceptions of South African primary school teachers and principals regarding the inclusion of learners considered gifted. Eight principals and 16 classroom teachers in the Foundation Phase (Grades 1-3 in public primary schools situated in communities that were representative of the different socio-economic and language groups in the Western Cape province participated in the study. Qualitative data collection methods included in-depth individual semi-structured interviews with the eight principals and two semi-structuredfocus group interviews with the 16 classroom teachers. Qualitative content analysis revealed the following themes: inclusive education and the learner who is gifted; curriculum differentiation; obstacles to curriculum differentiation; and possible solutions for more effectively including the gifted learner. Despite their diversity in terms of culture, language and positioning by the previous apartheid regime, the participants acknowledged the marginalisation by default of gifted learners. Gifted learners were most often those who were not receiving appropriate education and support and data suggested that a particular drive for the inclusion of gifted learners was absent in the agenda of education authorities.

    Full Text Available With the development of educational technology, the concept of technology-enhanced multimedia instructions is using widely in the educational settings. Technology can be employed in teaching different skills such as listening, reading, speaking and writing. Among these skills, reading comprehension is the skill in which EFL learners have some problems to master. Regarding this issue, the present study aimed at investigating the effect of video materials on improving reading comprehension of Iranian intermediate EFL learners. A Longman Placement Test was administered to 30 EFL learners to ensure that learners are at the same level of proficiency. The students were chosen from the state high schools in Chabahar.  The participants were regarded as intermediate learners and were divided into two groups (one experimental group and one control group. Then, a pre-test of reading comprehension was administered to assess the participants’ reading comprehension. The participants of experimental group used video files to improve their reading comprehension while the control group received conventional approaches of teaching reading comprehension. Finally, all the participants were assigned a 40-item multiple-choice reading comprehension post-test. The results of the study indicated that video materials had a significant effect on promoting reading comprehension of Iranian intermediate EFL learners (p = .000, <.05.

  13. When learners become teachers: a review of peer teaching in medical student education.

    Peer teaching engages students as teachers and is widely used in K-12 education, many universities, and increasingly in medical schools. It draws on the social and cognitive congruence between learner and teacher and can be attractive to medical schools faced with a growing number of learners but a static faculty size. Peer teachers can give lectures on assigned topics, lead problem-based learning sessions, and provide one on one support to classmates in the form of tutoring. We undertook a narrative review of research on peer teachers in medical school, specifically investigating how medical students are impacted by being peer teachers and how having a peer teacher impacts learners. Studies have shown that peer teaching has a primarily positive impact on both the peer teacher and the learners. In the setting of problem-based learning courses or clinical skills instruction, medical students' performance on tests of knowledge or skills is similar whether they have faculty instructors or peer teachers. There is also strong evidence that being a peer teacher enhances the learning of the peer teacher relative to the content being taught. It is common for peer teachers to lack confidence in their abilities to successfully teach, and they appreciate receiving training related to their teaching role. We find evidence from several different educational settings that peer teaching benefits both the peer teachers and the learners. This suggests that peer teaching is a valuable methodology for medical schools to engage learners as teachers.

  14. Receiving right/wrong feedback: consequences for learning.

    Fazio, Lisa K; Huelser, Barbie J; Johnson, Aaron; Marsh, Elizabeth J

    2010-04-01

    Prior work suggests that receiving feedback that one's response was correct or incorrect (right/wrong feedback) does not help learners, as compared to not receiving any feedback at all (Pashler, Cepeda, Wixted, & Rohrer, 2005). In three experiments we examined the generality of this conclusion. Right/wrong feedback did not aid error correction, regardless of whether participants learned facts embedded in prose (Experiment 1) or translations of foreign vocabulary (Experiment 2). While right/wrong feedback did not improve the overall retention of correct answers (Experiments 1 and 2), it facilitated retention of low-confidence correct answers (Experiment 3). Reviewing the original materials was very useful to learners, but this benefit was similar after receiving either right/wrong feedback or no feedback (Experiments 1 and 2). Overall, right/wrong feedback conveys some information to the learner, but is not nearly as useful as being told the correct answer or having the chance to review the to-be-learned materials.

    Background The oncology education framework currently in use in Canadian medical training programs is unknown, and the needs of learners have not been fully assessed to determine whether they are adequately prepared to manage patients with cancer. Methods To assess the oncology education framework currently in use at Canadian medical schools and residency training programs for family (fm) and internal medicine (im), and to evaluate opinions about the content and utility of standard oncology education objectives, a Web survey was designed and sent to educators and learners. The survey recipients included undergraduate medical education curriculum committee members (umeccms), directors of fm and im programs, oncologists, medical students, and fm and im residents. Results Survey responses were received from 677 educators and learners. Oncology education was felt to be inadequate in their respective programs by 58% of umeccms, 57% of fm program directors, and 50% of im program directors. For learners, oncology education was thought to be inadequate by 67% of medical students, 86% of fm residents, and 63% of im residents. When comparing teaching of medical subspecialty–related diseases, all groups agreed that their trainees were least prepared to manage patients with cancer. A standard set of oncology objectives was thought to be possibly or definitely useful for undergraduate learners by 59% of respondents overall and by 61% of postgraduate learners. Conclusions Oncology education in Canadian undergraduate and postgraduate fm and im training programs are currently thought to be inadequate by a majority of educators and learners. Developing a standard set of oncology objectives might address the needs of learners. PMID:24523624

    Making a conflict of interest declaration is now mandatory at continuing medical education CME accredited events. However, these declarations tend to be largely perfunctory. This study sought to better understand physician perceptions surrounding conflict of interest. The same PowerPoint (Microsoft, Canada) presentation (http://www.youtube.com/watch?v=mQSOvch7Yg0&feature=g-upl) was delivered at multiple University of Alberta and Royal College CME-accredited events to surgeons, internists, and learners. After each talk, the audience was invited to complete an anonymous, pretested, and standardized 5-point Likert scale (strongly disagree to strongly agree) questionnaire. A total of 136 surveys were analyzed from 31 surgeons, 49 internists, and 56 learners. In response to the question regarding whether by simply making a declaration, the speaker had provided adequate proof of any conflicts of interest, 71% of surgeons thought so, whereas only 35% of internists and 39% of learners agreed or strongly agreed (P = .004). Further probing this theme, the audience was asked whether a speaker must declare fees or monies received from industry for consulting, speaking, and research support. Once again there was a variance of opinion, with only 43% of surgeons agreeing or strongly agreeing with this statement; yet, 80% of internists and 71% of learners felt that such a declaration was necessary (P = .013). On the topic of believability (a speaker declaration makes him or her and the presentation more credible), the 3 groups were less polarized: 50% of surgeons, 41% of internists, and 52% of learners (P = .2) felt that this was the case. Although two thirds of surgeons (68%) and learners (66%) and nearly all internists (84%) felt that industry-sponsored research was biased, these differences were not significant (P = .2). Even when they are completely open and honest, conflict of interest declarations do not negate the biases inherent in a speaker's talk or research when it is

    Abstract: When deciding on the best learners' dictionary for a specific user and a specificsituation of usage one often has to make a choice between a monolingual and a bilingual learners'dictionary. This article discusses some aspects of the user-driven approach so prevalent in moderndaylexicographic thought, focuses broadly on dictionary typology and takes a closer look at monolingualand bilingual learners' dictionaries. Some problems users experience when learning a newlanguage, e.g. language distortion and problems related to the phenomenon of false friends, especiallyin closely related languages, are mentioned. It is indicated that a typological hybrid dictionarycould assist certain users. The importance of an unambiguous identification of the relevantlexicographic functions is emphasised and the notions of function condensation and function mergingare introduced. It is shown that the typological choice should be determined by a function-basedapproach to dictionary usage.

    An improved long-life design for solar energy receivers provides for greatly reduced thermally induced stress and permits the utilization of less expensive heat exchanger materials while maintaining receiver efficiencies in excess of 85% without undue expenditure of energy to circulate the working fluid. In one embodiment, the flow index for the receiver is first set as close as practical to a value such that the Graetz number yields the optimal heat transfer coefficient per unit of pumping energy, in this case, 6. The convective index for the receiver is then set as closely as practical to two times the flow index so as to obtain optimal efficiency per unit mass of material.

    The channelized receiver being presented demonstrates the use of high temperature superconductor technology in a microwave system setting where superconductor, microwave-monolithic-integrated-circuit, and hybrid-integrated-circuit components are united in one package and cooled to liquid-nitrogen temperatures. The receiver consists of a superconducting X-band four-channel demultiplexer with 100-MHz-wide channels, four commercial monolithically integrated mixers, and four custom-designed hybrid-circuit detectors containing heterostructure ramp diodes. The composite receiver unit has been integrated into the payload of the second-phase NRL high temperature superconductor space experiment (HTSSE-II). Prior to payload assembly, the response characteristics of the receiver were measured as functions of frequency, temperature, and drive levels. The article describes the circuitry, discusses the key issues related to design and implementation, and summarizes the experimental results

  11. Receiver Gain Modulation Circuit

    Jones, Hollis; Racette, Paul; Walker, David; Gu, Dazhen

    2011-01-01

    A receiver gain modulation circuit (RGMC) was developed that modulates the power gain of the output of a radiometer receiver with a test signal. As the radiometer receiver switches between calibration noise references, the test signal is mixed with the calibrated noise and thus produces an ensemble set of measurements from which ensemble statistical analysis can be used to extract statistical information about the test signal. The RGMC is an enabling technology of the ensemble detector. As a key component for achieving ensemble detection and analysis, the RGMC has broad aeronautical and space applications. The RGMC can be used to test and develop new calibration algorithms, for example, to detect gain anomalies, and/or correct for slow drifts that affect climate-quality measurements over an accelerated time scale. A generalized approach to analyzing radiometer system designs yields a mathematical treatment of noise reference measurements in calibration algorithms. By treating the measurements from the different noise references as ensemble samples of the receiver state, i.e. receiver gain, a quantitative description of the non-stationary properties of the underlying receiver fluctuations can be derived. Excellent agreement has been obtained between model calculations and radiometric measurements. The mathematical formulation is equivalent to modulating the gain of a stable receiver with an externally generated signal and is the basis for ensemble detection and analysis (EDA). The concept of generating ensemble data sets using an ensemble detector is similar to the ensemble data sets generated as part of ensemble empirical mode decomposition (EEMD) with exception of a key distinguishing factor. EEMD adds noise to the signal under study whereas EDA mixes the signal with calibrated noise. It is mixing with calibrated noise that permits the measurement of temporal-functional variability of uncertainty in the underlying process. The RGMC permits the evaluation of EDA by

    The learner model in an intelligent learning system (ILS) has to ensure the personalization (individualization) and the adaptability of e-learning in an online learner-centered environment. ILS is a distributed e-learning system whose modules can be independent and located in different nodes (servers) on the Web. This kind of e-learning is achieved through the resources of the Semantic Web and is designed and developed around a course, group of courses or specialty. An essential part of ILS is learner model database which contains structured data about learner profile and temporal status in the learning process of one or more courses. In the paper a learner model position in ILS is considered and a relational database is designed from learner's domain ontology. Multidimensional modeling agent for the source database is designed and resultant learner data cube is presented. Agent's modules are proposed with corresponding algorithms and procedures. Multidimensional (OLAP) analysis guidelines on the resultant learner module for designing dynamic learning strategy have been highlighted.

    2009-01-01

    Full Text Available The article explores the possibility of adopting a form-to-function perspective when annotating learner corpora in order to get deeper insights about systematic features of interlanguage. A split between forms and functions (or categories is desirable in order to avoid the "comparative fallacy" and because – especially in basic varieties – forms may precede functions (e.g., what resembles to a "noun" might have a different function or a function may show up in unexpected forms. In the computer-aided error analysis tradition, all items produced by learners are traced to a grid of error tags which is based on the categories of the target language. Differently, we believe it is possible to record and make retrievable both words and sequence of characters independently from their functional-grammatical label in the target language. For this purpose at the University of Pavia we adapted a probabilistic POS tagger designed for L1 on L2 data. Despite the criticism that this operation can raise, we found that it is better to work with "virtual categories" rather than with errors. The article outlines the theoretical background of the project and shows some examples in which some potential of SLA-oriented (non error-based tagging will be possibly made clearer.

  8. 'Chaos' in superregenerative receivers

    International Nuclear Information System (INIS)

    Commercon, Jean-Claude; Badard, Robert

    2005-01-01

    The superregenerative principle has been known since the early 1920s. The circuit is extremely simple and extremely sensitive. Today, superheterodyne receivers generally supplant superregenerative receivers in most applications because there are several undesirable characteristics: poor selectivity, reradiation, etc. Superregenerative receivers undergo a revival in recent papers for wireless systems, where low cost and very low power consumption are relevant: house/building meters (such as water, energy, gas counter), personal computer environment (keyboard, mouse), etc. Another drawback is the noise level which is higher than that of a well-designed superheterodyne receiver; without an antenna input signal, the output of the receiver hears in an earphone as a waterfall noise; this sound principally is the inherent input noise amplified and detected by the circuit; however, when the input noise is negligible with respect of an antenna input signal, we are faced to an other source of 'noise' self-generated by the superregenerative working. The main objective of this paper concerns this self-generated noise coming from an exponential growing followed by a re-injection process for which the final state is a function of the phase of the input signal

In fiscal 1995, the effect of irradiation of excimer laser and YGA(SHG) on ablation of aggregates of N2, CH4, Ar, Kr and Xe, and the effect of time-delayed irradiation of YGA(SHG) and KrF excimer laser on ablation of N2 aggregate were studied aiming at exciting ablation by cryogenic aggregate alone. Experimental results by a newly developed multi-laser excitation experiment equipment are as follows. Ablation was not caused by KrF excimer laser irradiation, while caused by YGA(SHG) irradiation. Ablation was caused by 1mm thick N2 or CH4 aggregate alone. Kr target was the most promising among rare gas solid targets expected as seed of ablation occurrence. Multi-irradiation showed a different ablation behavior as compared with single YGA(SHG) irradiation, and in some cases, multi-irradiation not increased scattering of particles. Time-delayed multi- irradiation (YGA(SHG) excitation after excimer excitation) was effective. 23 figs., 4 tabs.

  10. Solar thermal central receivers

    International Nuclear Information System (INIS)

    1993-01-01

    Market issues, environmental impact, and technology issues related to the Solar Central Receiver concept are addressed. The rationale for selection of the preferred configuration and working fluid are presented as the result of a joint utility-industry analysis. A $30 million conversion of Solar One to an external molten salt receiver would provide the intermediate step to a commercial demonstration plant. The first plant in this series could produce electricity at 11.2 cents/kWhr and the seventh at 8.2 cents/kWhr, completely competitive with projected costs of new utility plants in 1992

    Oliveira, Luis

    2015-01-01

    This book demonstrates how to design a wideband receiver operating in current mode, in which the noise and non-linearity are reduced, implemented in a low cost single chip, using standard CMOS technology.  The authors present a solution to remove the transimpedance amplifier (TIA) block and connect directly the mixer’s output to a passive second-order continuous-time Σ∆ analog to digital converter (ADC), which operates in current-mode. These techniques enable the reduction of area, power consumption, and cost in modern CMOS receivers.

  12. Receiver gain function: the actual NMR receiver gain

    OpenAIRE

    Mo, Huaping; Harwood, John S.; Raftery, Daniel

    2010-01-01

    The observed NMR signal size depends on the receiver gain parameter. We propose a receiver gain function to characterize how much the raw FID is amplified by the receiver as a function of the receiver gain setting. Although the receiver is linear for a fixed gain setting, the actual gain of the receiver may differ from what the gain setting suggests. Nevertheless, for a given receiver, we demonstrate that the receiver gain function can be calibrated. Such a calibration enables accurate compar...

    2014-07-01

    Full Text Available Open Universities across the world are embracing ICT based teaching and learning process to disseminate quality education to their learners spread across the globe. In India availability and access of ICT and learner characteristics are uneven and vary from state to state. Hence it is important to establish the facts about ICT access among learners, their ICT usage patterns and their readiness to use ICT for educational purpose. In view of this, a study was conducted with the objective to find out the access level of ICT among distance learners. The analysis indicates that maximum learners have desktop/laptops and most of them are accessing internet very frequently from their home. The analysis also indicates that maximum respondents are browsing social networking sites followed by educational and e-mail service providing websites. Findings suggest that there is a need to generate ICT based tutorials complemented with social networking tools and mobile applications. Study also shows that learners are equipped with mobile phones and they are browsing internet through it and also availing support services offered by the university. Hence possibility of integrating mobile phone services may be used for providing learner support services and content delivery.

    Blake, Patricia; Louw, Johann

    2010-12-01

    Learners' perceptions of aspects of school life that are sufficiently serious to interfere with their schoolwork were investigated. Bullying was a form of behaviour that was singled out for inclusion and further exploration in the study. Learners from three coeducational Western Cape Education Department schools were surveyed: 414 Grade 8 and 474 Grade 9 learners completed an anonymous, voluntary self-report questionnaire. Factors identified as most frequently interfering with their schoolwork included classmates not listening in class, feeling overwhelmed by schoolwork, teacher absenteeism, and verbal fighting. When asked specifically about bullying, 40% of learners indicated that they frequently experienced bullying at school-although they ranked it as much lower when compared to other potentially problematic school experiences. Furthermore, although the majority of learners indicated they thought teachers considered bullying a problem, few felt there was anything that school staff could do to counteract bullying effectively. These findings suggest that learners perceive bullying as an unavoidable part of school experience and have normalised this aggressive behaviour.

  3. Digital Receiver Phase Meter

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density measurements in laser metrology of moving bodies. To illustrate part of the principle of operation of the phase meter, the figure includes a simplified block diagram of a basic singlechannel digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

    Mostert, Hendrik P; Myburgh, Chris; Poggenpoel, Marie

    2012-10-04

    In schools today discrimination based on sexual orientation takes place on a regular basis. This form of discrimination leads to aggression towards learners perceived to be homosexual, as well as towards those with a homosexual orientation. For more than 15 years South Africa has been a democratic country with laws that protect learners who have a homosexual orientation. Nevertheless, aggression and discrimination towards these learners still occur in schools. Aggression often leads to verbal and physical bullying of the victims by perpetrators. The objectives of this research were to explore and describe Grade 11 learners' experiences of aggression towards learners perceived to be homosexual as well as those with a homosexual orientation in an independent secondary school environment. The research design was qualitative, exploratory, descriptive and contextual in nature. The data for this investigation consisted of essays based on a published newspaper photograph, phenomenological group interviews, observations and field notes. Tesch's method of data analysis was used, and an independent coder assisted. Three themes were identified, discussed and supported by a literature control: that learners experience that it is right and acceptable to have a homosexual orientation; that they experience ambivalence towards homosexual orientation of learners; and experienced feelings that it is wrong to have a homosexual orientation. Recommended guidelines are provided to address aggression towards learners perceived to be homosexual and those with a homosexual orientation.

    A plurality of heat pipes in a shell receive concentrated solar energy and transfer the energy to a heat activated system. To provide for even distribution of the energy despite uneven impingement of solar energy on the heat pipes, absence of solar energy at times, or failure of one or more of the heat pipes, energy storage means are disposed on the heat pipes which extend through a heat pipe thermal coupling means into the heat activated device. To enhance energy transfer to the heat activated device, the heat pipe coupling cavity means may be provided with extensions into the device. For use with a Stirling engine having passages for working gas, heat transfer members may be positioned to contact the gas and the heat pipes. The shell may be divided into sections by transverse walls. To prevent cavity working fluid from collecting in the extensions, a porous body is positioned in the cavity.

  12. LEARNER AUTONOMY IN THE INDONESIAN EFL SETTINGS

    Directory of Open Access Journals (Sweden)

    Nenden Sri Lengkanawati

    2017-01-01

    Full Text Available Learner autonomy in Indonesian educational institutions has not commonly been listed as a teaching-learning objective, and most teachers seem to be hardly acquainted with learner autonomy (LA.  Therefore, it is very essential  to conduct a study of LA as perceived and experienced by school teachers and to find out the importance of LA training for professional development. A questionnaire was used to collect the data about English teachers’ perceptions regarding LA and LA-based practices. In addition, an LA training was conducted to see its significance for professional development.  After the data were qualitatively and quantitatively analyzed, it was found that the participating teachers tended to maintain that autonomy should be inculcated among learners, and that the LA concept should not be misinterpreted as learning without a teacher. Concerning choices and decisions by  the learners, it was believed that learners’ making choices about how they learned and what activities they did, and involving them to decide what and how to learn could promote autonomy among learners. As regards LA-based teaching-learning practices, it was revealed that most teachers desired to implement LA principles in their teaching-learning contexts, although they identified that many of the LA principles were not that feasible to apply in their situation. It was also found that LA training could improve the teachers’ perceptions regarding LA concepts and principles. There were some constraints which could make learner autonomy difficult to develop among Indonesian learners in general: limited time allotted for the implementation of the curriculum, learners’ lack of autonomous learning experience, too much focus on national examinations, and insufficient proficiency of English.  LA-based teaching-learning practices were most desired; however, many were considered as having insufficient feasibility. In this respect, commitment is certainly the key to

    2013-07-01

    Full Text Available Most of the early studies in the field of language learning strategies focused on identifying the characteristics of good language learners. Identifying and discussing the strategies used by good language learners were considered as a good way to make the learners aware of the notion of language learning strategies. The present study was an attempt to collect and classify the characteristics of representative good language learners, developing English as a foreign /second language in Iran; specifically those who had achieved high scores in the IELTS General Module. And also this study aimed at identifying the characteristics associated with a good language learner in one area: learning strategies. Thirty-four Iranian IELTS candidates receiving 6+ band score were selected to participate in this study. They were interviewed and asked to write down their own reports of the experiences they had in developing their second language. They were asked to report their preferred strategies while studying English as well. They were also requested to fill out the learning strategy and learning style questionnaires. The results of interviews and open ended questions were specifically organized and classified via employing both descriptive and explanatory methods. The learners’ responses to the standardized questionnaires also were analyzed by SPSS system Version 20. The findings of the present study although revealed that there is a high correlation between IELTS scores, strategy taking inventory scores. This revealed that the learners recording high scores in IELTS use appropriate learning strategies.

  14. Interface between problem-based learning and a learner-centered paradigm.

    2011-01-01

    Problem-based learning (PBL) has made a major shift in support of student learning for many medical school curricula around the world. Since curricular development of PBL in the early 1970s and its growth in the 1980s and 1990s, there have been growing numbers of publications providing positive and negative data in regard to the curricular effectiveness of PBL. The purpose of this study was to explore supportive data for the four core objectives of PBL and to identify an interface between the objectives of PBL and a learner-centered paradigm. The four core PBL objectives, ie, structuring of knowledge and clinical context, clinical reasoning, self-directed learning, and intrinsic motivation, were used to search MEDLINE, the Education Resources Information Center, the Educator's Reference Complete, and PsycINFO from January 1969 to January 2011. The literature search was facilitated and narrowed if the published study included the following terms: "problem-based learning", "medical education", "traditional curriculum", and one of the above four PBL objectives. Through a comprehensive search analysis, one can find supportive data for the effectiveness of a PBL curriculum in achieving the four core objectives of PBL. A further analysis of these four objectives suggests that there is an interface between PBL objectives and criteria from a learner-centered paradigm. In addition, this review indicates that promotion of teamwork among students is another interface that exists between PBL and a learner-centered paradigm. The desire of medical schools to enhance student learning and a need to provide an environment where students construct knowledge rather than receive knowledge have encouraged many medical schools to move into a learner-centered paradigm. Implementation of a PBL curriculum can be used as a prevailing starting point to develop not only a learner-centered paradigm, but also to facilitate a smooth curricular transition from a teacher-centered paradigm to a

  20. Working with language learner histories from three perspectives: Teachers, learners and researchers

    Directory of Open Access Journals (Sweden)

    Sarah Mercer

    2013-10-01

    Full Text Available Recent developments in SLA, such as learner-centredness, social constructivism, the postmethod era, and complexity perspectives, have highlighted the need for more localized, situated understandings of teaching and learning and greater recognition of learner individuality and diversity. In this article, I suggest an effective way of meeting these needs is to employ learner histories. This powerful form of writing allows learners to use their L2 to engage in authentic, personally meaningful communication with others about their identities, experiences, perceptions and emotions related to their language learning histories. As a text type, they are able to facilitate a more holistic perspective of the learner’s life and reveal the unique interconnections that an individual makes across various domains. They also enable the situated, contextualised and dynamic nature of their learning experiences to become apparent and provide learners with a genuine, motivating purpose for writing. Exploring data generated in Austria with tertiary-level EFL learners, I seek to illustrate some of the rich potential of these text types from three perspectives, namely, those of the teacher, learner and researcher.

    As a result of the paradigm shift to a competency-based framework, both self-directed lifelong learning and learner-centeredness have become essential tenets of medical education. In the competency-based framework, learners drive their own educational process, and both learners and teachers share the responsibility for the path and content of learning. This learner-centered emphasis requires each physician to develop and maintain lifelong learning skills, which the authors propose culminate in becoming a "master leaner." To better understand the development of these skills and the attainment of that goal, the authors explore how learning theories inform the development of master learners and how to translate these theories into practical strategies for the learner, the teacher, and the learning environment so as to optimize this development.The authors begin by exploring self-determination theory, which lays the groundwork for understanding the motivation to learn. They next consider the theories of cognitive load and situated cognition, which inform the optimal context and environment for learning. Building from this foundation, the authors consider key educational theories that affect learners' abilities to serve as primary drivers of their learning, including self-directed learning (SDL); the self-assessment skills necessary for SDL; factors affecting self-assessment (self-concept, self-efficacy, illusory superiority, gap filling); and ways to mitigate the inaccuracies of self-assessment (reflection, self-monitoring, external information seeking, and self-directed assessment seeking).For each theory, they suggest practical action steps for the learner, the teacher, and the learning environment in an effort to provide a road map for developing master learners.

  13. Repair and fixation of potentially lethal damage (PLD) as demonstrated by delayed plating or incubation with araA in contact inhibited refed plateau-phase C3H mouse embryo 10T1/2 cells grown in the presence of BrdUrd

    International Nuclear Information System (INIS)

    Iliakis, G.; Wright, E.; Ngo, F.Q.H.

    1987-01-01

    CH3 mouse 10 T 1/2 cells showing strong inhibition of growth at confluency were grown under daily refeeding in the presence of BrdUrd (from 0 to 1 μM) and exposed to γ-rays either while exponentially growing or in the plateau phase. An increase in radiosensitivity was observed in both growth conditions mainly reflected by a reduction in Dq. Greater radiosensitization was observed in exponentially growing than in plateau-phase cells, and 3-4 times higher BrdUrd concentrations were required in plateau-phase cells for similar potentiation in killing. This effect could not be entirely attributed to a reduction in BrdUrd incorporation since measurements with 3 H-BrdUrd showed reductions in incorporation between only 17-47% in plateau-phase cells. The rate of repair of potentially lethal damage (PLD) as demonstrated by delayed plating was not affected by the incorporation of BrdUrd, but the amount of repair (measured as the relative increase in cell survival) was higher for BrdUrd containing cells. Post-irradiation treatment of cells in the plateau-phase (no BrdUrd) with 9-β-D-arabinofuranosyladenine (araA) caused fixation of radiation-induced PLD. AraA treatment of cells grown in the presence of various amounts of BrdUrd also caused fixation of PLD, but resulted in survival levels similar to those observed with cells growing in BrdUrd-free medium. This result indicates that BrdUrd mediated radiosensitization cannot be observed when cells are prevented from repairing PLD by postirradiation incubation with araA. Based on these findings we propose that the mechanism of radiosensitization by BrdUrd incorporation might be, by increasing probability of fixation, mediated by the postirrdiation progression of cells through the cycle, of a sector of PLD also sensitive to post-irradiation treatment with araA. For this sector of PLD the term α-PLD has been proposed. (orig.)

  14. Literacy development of English language learners: The outcomes of an intervention programme in grade R

    2010-12-01

    Full Text Available This study aims to contribute to the knowledge base on the status and development of emergent literacy skills of learners receiving formal education in their second or additional language. The focus is on young English language learners (ELLs, i.e. learners whose home language is not English but who have English as their language of teaching and learning. This article reports on a study that investigated ELLs’ emergent literacy skills prior to entering grade 1 and then evaluated the effectiveness of an evidence-based stimulation programme on early literacy skills in the South African context. Using a quasi-experimental design, ELLs’ emergent literacy skills were assessed with an adapted version of 8 of the subtests of the Emergent Literacy Assessment battery (Willenberg, 2004 and were compared to those of English first language (L1 and of ELL control groups, both before and after the 8-week purpose-designed programme. While learners showed significant improvement on 6 of the 8 subtests, the programme did not significantly improve ELLs’ skills in comparison to those of the control groups. Possible independent variables contributing to the dearth of intervention effect include socio-economic status, learners’ L1, and teacher- and classroom-specific characteristics, all of which were considered in this study. Clinical implications for speech-language therapists with regard to assessment, intervention, service delivery and outcome measures are highlighted.

  15. Corrective feedback, learner uptake, and feedback perception in a Chinese as a foreign language classroom

    2016-03-01

    Full Text Available The role of corrective feedback in second language classrooms has received considerable research attention in the past few decades. However, most of this research has been conducted in English-teaching settings, either ESL or EFL. This study examined teacher feedback, learner uptake as well as learner and teacher perception of feedback in an adult Chinese as a foreign language classroom. Ten hours of classroom interactions were videotaped, transcribed and coded for analysis. Lyster and Ranta’s (1997 coding system involving six types of feedback was initially used to identify feedback frequency and learner uptake. However, the teacher was found to use a number of additional feedback types. Altogether, 12 types of feedback were identified: recasts, delayed recasts, clarification requests, translation, metalinguistic feedback, elicitation, explicit correction, asking a direct question, repetition, directing question to other students, re-asks, and using L1-English. Differences were noted in the frequency of some of the feedback types as well as learner uptake compared to what had been reported in some previous ESL and EFL studies. With respect to the new feedback types, some led to noticeable uptake. As for the students’ and teacher’s perceptions, they did not match and both the teacher and the students were generally not accurate in perceiving the frequency of each feedback type. The findings are discussed in terms of the role of context in affecting the provision and effectiveness of feedback and its relationship to student and teacher perception of feedback.

    2001-01-01

    Full Text Available Learning a new language is ultimately to be able to communicate with it. Encouraging a sense of responsibility on the part of the learners is crucial for training them to be proficient communicators. As such, understanding the strategies that they employ in acquiring the language skill is important to come to ideas of how to promote learner autonomy. Research recently conducted with three different groups of learners of English at the tertiary education level in Malang indicated that they used metacognitive and social startegies at a high frequency, while memory, cognitive, conpensation, and affective strategies were exercised at a medium frewuency. This finding implies that the learners have acquired some degrees of autonomy because metacognive strategies requires them to independently make plans for their learning activities as well as evaluate the progress, and social strategies requires them to independently enhance communicative interactions with other people. Further actions are then to be taken increase their learning autonomy, that is by intensifying the practice of use of the other four strategy categories, which are not yet applied intensively.

  15. Development of affective modelling competencies in primary school learners

    Piera Biccard

    2011-09-01

    Full Text Available Learner affect and beliefs about mathematics are complex and multifaceted aspects of mathematical learning. Traditional teaching and learning approaches in mathematics education often result in problematic beliefs about mathematics. Since beliefs influence what learners learn and how they deal with learning mathematics, it is essential that the roles of beliefs and affect in mathematics classrooms are carefully examined. In solving modelling problems, learners and teachers take on new roles in the classroom: learners are placed in an active, self-directing situation in which they solve real-world problems. When learners engage in modelling tasks, they display and integrate cognitive, meta-cognitive and affective competencies. A modelling approach therefore allows one to detect learner beliefs in an authentic learning environment. Will this environment lead to students having more positive and productive dispositions towards mathematics? This article presents partial results of a study documenting the development of modelling competencies in learners working in groups over a period of 12 weeks. Through a design research approach, 12 learners working in groups solved three modelling problems, and transcriptions of learner interactions, questionnaires and informal interviews revealed that learner beliefs improved over this short period when exposed to modelling tasks. The results are encouraging, and may provide mathematics education with an avenue to develop more positive learner beliefs in mathematics.

    Full Text Available This research will explore teaching styles of university professors. Teaching style is an umbrella term for teaching decisions made during the entire teaching process – planning, delivery, and evaluation. Contemporary university teachers are advised to adopt the learner-centred teaching style which is assumed to produce remarkable possibilities. In the Fall Semester 2015 fifty-two respondents in different faculties of International University of Sarajevo were surveyed using The Principles of Adult Learning Scale inventory designed by Gary J. Conti. Inventory scores were calculated according to guidelines suggested by the author of the inventory. The scores revealed that majority of respondents strongly supported teacher-centred rather than learner-centred styles of instruction. Scores were analysed on gender lines and across three different faculties, namely: Arts and Social Sciences; Business and Administration; Engineering and Natural Sciences. In all five groups none of the seven teaching style indicators was found to conform with the learner-centred teaching criteria. There was no statistically significant difference between the two genders’ preference for a teaching style. And there was no statistically significant difference between teaching style preference across the three different faculties.The results of this research imply that the learner-centred style of instruction is not frequently implemented. Secondly, the results indicate that the requirements necessary for proper application of the learner-centred teaching style are not easy to meet in current written and unwritten norms. Finally, the results show that traditional teaching styles, which have been preserved in different scientific fields, still predominate in universities.

    Bopardikar, Anushree; Bernstein, Debra; Drayton, Brian; McKenney, Susan

    2018-05-01

    Around the globe, science education during compulsory schooling is envisioned for all learners regardless of their educational and career aspirations, including learners bound to the workforce upon secondary school completion. Yet, a major barrier in attaining this vision is low learner participation in secondary school science. Because curricula play a major role in shaping enacted learning, this study investigated how designers developed a high school physics curriculum with positive learning outcomes in learners with varied inclinations. Qualitative analysis of documents and semistructured interviews with the designers focused on the curriculum in different stages—from designers' ideas about learning goals to their vision for enactment to the printed materials—and on the design processes that brought them to fruition. This revealed designers' emphases on fostering workplace connections via learning goals and activities, and printed supports. The curriculum supported workplace-inspired, hands-on design-and-build projects, developed to address deeply a limited set of standards aligned learning goals. The curriculum also supported learners' interactions with relevant workplace professionals. To create these features, the designers reviewed other curricula to develop vision and printed supports, tested activities internally to assess content coverage, surveyed states in the USA receiving federal school-to-work grants and reviewed occupational information to choose unit topics and career contexts, and visited actual workplaces to learn about authentic praxis. Based on the worked example, this paper offers guidelines for designing work-based science curriculum products and processes that can serve the work of other designers, as well as recommendations for research serving designers and policymakers.

    Full Text Available Reza KarimiPacific University School of Pharmacy, Hillsboro, OR, USABackground: Problem-based learning (PBL has made a major shift in support of student learning for many medical school curricula around the world. Since curricular development of PBL in the early 1970s and its growth in the 1980s and 1990s, there have been growing numbers of publications providing positive and negative data in regard to the curricular effectiveness of PBL. The purpose of this study was to explore supportive data for the four core objectives of PBL and to identify an interface between the objectives of PBL and a learner-centered paradigm.Methods: The four core PBL objectives, ie, structuring of knowledge and clinical context, clinical reasoning, self-directed learning, and intrinsic motivation, were used to search MEDLINE, the Education Resources Information Center, the Educator’s Reference Complete, and PsycINFO from January 1969 to January 2011. The literature search was facilitated and narrowed if the published study included the following terms: “problem-based learning”, “medical education”, “traditional curriculum”, and one of the above four PBL objectives.Results: Through a comprehensive search analysis, one can find supportive data for the effectiveness of a PBL curriculum in achieving the four core objectives of PBL. A further analysis of these four objectives suggests that there is an interface between PBL objectives and criteria from a learner-centered paradigm. In addition, this review indicates that promotion of teamwork among students is another interface that exists between PBL and a learner-centered paradigm.Conclusion: The desire of medical schools to enhance student learning and a need to provide an environment where students construct knowledge rather than receive knowledge have encouraged many medical schools to move into a learner-centered paradigm. Implementation of a PBL curriculum can be used as a prevailing starting point to

    2016-01-01

    The author examines the theory and research relevant to educating d/Deaf and Hard of Hearing Multilingual Learners (DMLs). There is minimal research on this population, yet a synthesis of related theory, research, and practice on spoken-language bilinguals can be used to add to the body of knowledge on these learners. Specifically, the author reports on three major areas: (a) population characteristics of DMLs, (b) theories relevant to understanding the language development of DMLs, and (c) considerations for programs in designing and implementing educational services for DMLs. In the interest of ensuring that children receive the foundation for linguistic success, aspects of linguistically responsive teaching (Lucas & Villegas, 2013) are addressed, with a focus on adopting an asset-based perspective on educating DMLs that honors all of a child's language, identity, and cultural memberships.

    In a Solar Central Internal Film Receiver, the heat absorbing fluid (a molten nitrate salt) flows in a thin film down over the non illuminated side of an absorber panel. Since the molten salt working fluid is not contained in complicated tube manifolds, the receiver design is simples than a conventional tube type-receiver resulting in a lower cost and a more reliable receiver. The Internal Film Receiver can be considered as an alternative to the Direct Absorption Receiver, in the event that the current problems of the last one can not be solved. It also describes here the test facility which will be used for its solar test, and the test plans foreseen. (Author) 17 refs

    Full Text Available The growth of enrolment in the ODL system has been considerable. However, another parameter of significance in the context of Open and Distance learning is the learner success rate. While enrolment rates have been very encouraging in distance education, the pass-out rates haven’t been similar. There is a need to focus on the dynamics involved after a learner enrols himself in an OU and what drives him to stay focussed and complete his academic pursuit successfully or alternatively what holds or slows his academic progress and eventually makes him drop out. The study highlights that there are both institution-based (that is OU-based and learner-centric factors that could facilitate learners to successfully complete their studies. There are both controllable and uncontrollable factors that affect the OU learners’ success rate. This study attempts to capture the learner-centric factors and OU-related factors that have facilitated the learners to successfully complete their study. The paper delves into those key aspects or factors which would have facilitated the passed out learners in successfully completing their programmes in the open system. The findings are of direct interest, both from an institution perspective and that of a distance learner. It provides inputs to the Open and distance learning system, towards formulating appropriate strategies that further facilitate learners to successfully pass out. Also the findings serve as indicators/guide rules for any learner in the open system.

    2015-12-01

    With the ever-increasing omnipresence of mobile devices in student life, leveraging smart devices to foster students' interaction with course content is critical. Following a learner-centered design iterative approach, we designed a mobile interface that may enable learners to access and interact with online course content efficiently and intuitively. Our design process leveraged recent technologies, such as bootstrap, Google's Material Design, HTML5, and JavaScript to design an intuitive, efficient, and portable mobile interface with a variety of built-in features, including context sensitive bookmarking, searching, progress tracking, captioning, and transcript display. The mobile interface also offers students the ability to ask context-related questions and to complete self-checks as they watch audio/video presentations. Our design process involved ongoing iterative feedback from learners, allowing us to refine and tweak the interface to provide learners with a unified experience across platforms and devices. The innovative combination of technologies built around well-structured and well-designed content seems to provide an effective learning experience to mobile learners. Early feedback indicates a high level of satisfaction with the interface's efficiency, intuitiveness, and robustness from both students and faculty.

    Full Text Available Concept mapping is an inquiry technique that provides students at all ages with opportunities to demonstrate learning through performance. A concept map refers to a graphic/visual representation of concepts with linking connections that show various relationships between concepts (Novak & Gowin, 1984. Assessment is an ongoing process integrated with instruction across subject areas. The National Council of Teachers of Mathematics (NCTM emphasizes that assessment should focus on both the enhancement of student learning as well as serve as a valuable tool for making instructional decisions (NCTM, 2000. Assessment activities can take on a variety of forms, one being performance tasks. In this manuscript, an explanation of concept mapping is provided for learners ages 3 – 12 along with several examples of concept maps for young learners, including examples from an assessment project in the subject area of mathematics. Also presented are the numerous benefits of the concept mapping technique for both students and teachers.

    Joko Pranowo

    2006-01-01

    Full Text Available The typical drawbacks that affect most Indonesian learners studying English as the target language concern the strategies in dealing with new dictions. The rule of thumb is that the learners are usually tempted to directly look up the meaning in a dictionary when other ways such as guessing the meaning from the context or by dissecting the words into smaller units so that they are able to get a hint from the base word cannot be engineered. As a result of this activity then, they miss crucial points in the realm of word enrichment. This article will shed some light on how to deal with new words and claim that it is not the meaning of a new word that should be the first priority.

The analysis shows the linguistic features utilized in the two writing samples, one that received a passing score and one that received a failing score. The article describes some of the grammatical resources which are functional for expository writing, which are divided under three main categories: textual, interpersonal, and ideational resources. Following this brief description is the analysis of both essays in terms of these resources.. The configuration of grammatical features used in the essays make up the detached style of essay 1 and the more personal style of essay 2. These grammatical features include the textual resources of thematic choices and development, clause-combining strategies (connectors, and lexical cohesion; interpersonal resources of interpersonal metaphors of modality; and ideational resources of nominalization and abstractions as ideational metaphors. Implications for educational practice and recommendations for educators based on the analysis are provided.

  12. The Relationship between Learner Autonomy and Vocabulary Learning Strategies in Iranian EFL Learners with Different Language Proficiency Level

    Directory of Open Access Journals (Sweden)

    Ebrahim Azimi Mohammad Abadi

    2013-05-01

    Full Text Available Vocabulary learning is incredibly noteworthy to English language acquisition. It is unfeasible for a learner to communicate without the required vocabulary. In high education levels, learners are habitually forced to become autonomous and make conscious effort to learn vocabulary outside of the classroom. Consequently, the autonomy of the learners plays an important role in developing and enhancing their vocabulary. Learner autonomy is a huge assistance for learners in vocabulary learning since it provides the learners with numerous diverse privileges such as independency from teacher. The researcher investigated whether there is any statistically significant relationship between learner autonomy and vocabulary learning strategies use in Iranian EFL learners with different language proficiency levels. To meet the above purpose, a total number of 190 male and female EFL learners participated in this study. The methodology underlying this study was quantitative (thorough the administration of two questionnaires and two language proficiency test – TOEFL for advanced group, and Nelson for intermediate level. The quantitative data was analyzed using a set of correlational analysis revealing a significant positive correlation between learner autonomy and vocabulary learning strategies use in high proficient group, and a significant positive relationship between these two constructs in low proficient group, however not as strong as in the advanced group.

    Distance learning represents a strategy for leveraging resources to solve educational and training needs. Although many distance learning programs have been developed, lessons learned regarding differences between distance learning and traditional education with respect to learner characteristics have not been well documented. Therefore, we conducted a survey of 20 distance learning professionals. The questionnaire was distributed to experts attending the second Distance Learning Conference sponsored by Los Alamos National Laboratory. This survey not only acquired demographic information from each of the respondents but also identified important distance learning student characteristics. Significant distance learner characteristics, which were revealed statistically and which influence the effectiveness of distance learning, include the following: reading level, student autonomy, and self-motivation. Distance learning cannot become a more useful and effective method of instruction without identifying and recognizing learner characteristics. It will be important to consider these characteristics when designing all distance learning courses. This paper will report specific survey findings and their implications for developing distance learning courses. 9 refs., 6 tabs.

    Learners with disabilities lag far behind their peers without disabilities in achievement, graduation rates, post-school education and employment outcomes [4]. Against the current state of education affairs in South Africa, where curriculum models for learners with special educational needs (LSEN) are still under revision, therapists and teachers are finding it difficult to prepare these learners for appropriate employment after school. Even where systems in education are established, persons with learning disabilities face more challenges to enter employment [5]. This article reports on a unique career exploration programme for grade 11 learners at a school for learners with special educational needs in Gauteng, South Africa. It is a collaborative strategy between the learners, their parents, a teacher and the occupational therapists at the school. Two case studies are described to indicate the success of the program.

    2018-05-01

    PLD (Pulsed Laser Deposition) method with high laser energy density (LED) above 10 J/cm2 followed by a flash annealing enabled us to obtain isotropic nano-composite thick-film magnets with (BH)max ≧ 80 kJ/m3 on polycrystalline Ta substrates. We also have demonstrated that a dispersed structure composed of α-Fe together with Nd2Fe14B phases with the average grain diameter of approximately 20 nm could be formed on the Ta substrates. In this study, we tried to enhance the (BH)max value by controlling the microstructure due to the usage of different metal based substrates with each high melting point such as Ti, Nb, and W. Although it was difficult to vary the microstructure and to improve the magnetic properties of the films deposited on the substrates, we confirmed that isotropic thick-film magnets with (BH)max ≧ 80 kJ/m3 based on the nano-dispersed α-Fe and Nd2Fe14B phases could be obtained on various metal substrates with totally different polycrystalline structure. On the other hand, the use of a glass substrate lead to the deterioration of magnetic properties of a film prepared using the same preparation process.

    Full Text Available The misleading assumptions of Indonesian-speaking learners of English on the nature of English results in psychological burden inhibiting the process of teaching and learning. The assumptions should be eliminated at the beginning of English class. Besides, the instructor should extensively motivate and encourage the learners to maximize their potentials in learning process. Such approach will gradually lead the learners to self-confidence and self-discovery.

    Compact, highly customizable digital receivers are being developed for the system described in 'Radar Interferometer for Topographic Mapping of Glaciers and Ice Sheets' (NPO-43962), NASA Tech Briefs, Vol. 31, No. 7 (August 2007), page 72. The receivers are required to operate in unison, sampling radar returns received by the antenna elements in a digital beam-forming (DBF) mode. The design of these receivers could also be adapted to commercial radar systems. At the time of reporting the information for this article, there were no commercially available digital receivers capable of satisfying all of the operational requirements and compact enough to be mounted directly on the antenna elements. A provided figure depicts the overall system of which the digital receivers are parts. Each digital receiver includes an analog-to-digital converter (ADC), a demultiplexer (DMUX), and a field-programmable gate array (FPGA). The ADC effects 10-bit band-pass sampling of input signals having frequencies up to 3.5 GHz. The input samples are demultiplexed at a user-selectable rate of 1:2 or 1:4, then buffered in part of the FPGA that functions as a first-in/first-out (FIFO) memory. Another part of the FPGA serves as a controller for the ADC, DMUX, and FIFO memory and as an interface between (1) the rest of the receiver and (2) a front-panel data port (FPDP) bus, which is an industry-standard parallel data bus that has a high data-rate capability and multichannel configuration suitable for DBF. Still other parts of the FPGA in each receiver perform signal-processing functions. The digital receivers can be configured to operate in a stand-alone mode, or in a multichannel mode as needed for DBF. The customizability of the receiver makes it applicable to a broad range of system architectures. The capability for operation of receivers in either a stand-alone or a DBF mode enables the use of the receivers in an unprecedentedly wide variety of radar systems.

    Full Text Available For second-language learners, monolingual dictionaries can be useful tools because they often provide more detailed explanations of meanings and more extensive vocabulary coverage than bilingual dictionaries do. While learners of English have access to many monolingual dictionaries designed specifically to meet their needs, learners of Japanese must make do with Kokugo dictionaries, that is, monolingual dictionaries intended for native Japanese speakers. This paper, after briefly describing Kokugo dictionaries in general, analyzes a typical entry from such a dictionary to illustrate the advantages and challenges of the use of Kokugo dictionaries by learners of Japanese.

    2016-01-01

    Full Text Available The paper is focuded on investigating the phenomenon of learner autonomy, which has mostly been explored in Europe and the USA and is now attracting attention of researchers and academics in many other countries including Russia. Learner autonomy through a focus on learner reflection and taking responsibility for one’s own learning processes has become a central concern in the recent history of language teaching. However, many language teachers, who are committed to concepts of learnercentredness and autonomy, struggle with the ways to foster learner autonomy or at least to encourage the idea of learner autonomy in language classroom. The study aims at investigating what the most important issues which have a great impact on developing learner autonomy are. Having given special attention to conditions which can insure development of learner autonomy, a model covering seven issues relating to the subject matter has been designed. The authors state that such aspects as choice, goals and needs, support, emotional climate, learning strategies, learner attitude and motivation, and self-esteem should be considered as the goal to promote learner autonomy in EFL context.

Students believe that in order to improve their writing skills, it is necessary to receive teacher feedback on written work both on paper or submitted electronically. They prefer immediate correction of errors in spite of its impracticality and claim that individual correction of mistakes by teacher is useful. Differences between the responses of students who study two disciplines were slight. Attitudes to feedback do not differ significantly—specialization is not very relevant. Criticism isn’t meant to undermine self-esteem, though some students were more confident than other students. Perceived merits of oral, handwritten, electronic, teacher and peer feedback as well as the value of statistical analysis in interpretation of data are discussed in this study.

    Full Text Available The present study was an attempt to investigate the effectiveness of reading instructional approach called MCSR- Modified Collaborative Strategic Reading on reducing intermediate EFL learner's reading anxiety. Based on a pretest-posttest design, MCSR was implemented with 64 EFL learners at intermediate level. They received EFL reading instruction according to MCSR over two and a half months. A questionnaire called English as a Foreign Language Reading Anxiety Inventory EFLRAI was group-administered atthepretest and the posttest. Quantitative results indicated that participating students demonstrated significant gains in reducing reading anxiety. This study highlighted our understanding by considering the effectiveness of MCSR program and also it elaborated the effects of using strategies like MCSR in overcoming the big problem of reading anxiety among EFL learners as non-native students. And teachers changed the focus of attention from using traditional methods for teaching the essential skill of reading to modern programs like MCSR in order to remove their students' anxiety and stress in reading.

    Full Text Available Technology is an indispensable part of our lives and education cannot be taught without it. Since technology is in every part of our lives, foreign language education also makes use of the new technology. By the use of the Internet, virtual classrooms and materials are easy to access and learning takes place beyond the boundaries of the classrooms. Weblogs or blogs are one of the tools that are used to teach language skills in EFL courses and students have a chance to reflect on what they wrote in the blogs. The aim of this study is to find the opinions of elementary level EFL learners on using weblogs and distance education. The subjects of the study were 10 Native speakers of English in London and 15 Turkish EFL learners who are learning English in the School of Foreign Languages. Turkish EFL learners created a class blog and every week they were given assignments by their class teacher. They wrote paragraphs and they gave and receive feedback on their writing in terms of content, vocabulary and grammar by their classmates and by native English speakers in a virtual environment. This procedure lasted for 6 weeks. At the end of 6 weeks, students were given an evaluation questionnaire and they were asked to write their opinions about using weblogs. They were also interviewed by their teacher and the opinions of the students were categorized. Findings indicate that the students found the idea of weblogs as a distant learning tool motivating, enjoyable and encouraging.

    Full Text Available This study was designed to investigate the impact of multimodal text on reading comprehension test performance of Iranian intermediate learners. A total of 80 students participated in this study. All of them were Iranian female EFL learners with the age ranging from 16 to 18. They were selected from a boarding high school in Nasr Abad, Torbat Jam in Khorasan e Razavi, Iran. The students were randomly settled in four groups, who received different instructional approaches through using linear texts, multimodal printed texts, non-printed multimodal texts, and both multimodal printed and non-printed texts.  A pre-test and post-test were used to find out the differences before and after the experimental treatment.  The results reflected that the printed and non-printed multimodal texts had significant impact on reading comprehension test performance. In contrast, applying linear texts or traditional texts did not exert significant influence on reading comprehension ability of the participants. The findings provide useful hints for language instructors to improve effectiveness of instructional reading curriculums and reading ability of language learners. The participants who learned reading comprehension through using multimodal printed and non-printed texts enjoy reading programs and develop their intrinsic and extrinsic motivation for improving reading ability.

    Providing the learner control over aspects of practice has improved the process of motor skill acquisition, and self-controlled knowledge of results (KR) schedules have shown specific advantages over externally controlled ones. A possible explanation is that self-controlled KR schedules lead learners to more active task involvement, permitting deeper information processing. This study tested this explanatory hypothesis. Thirty undergraduate volunteers of both sexes, aged 18 to 35, all novices in the task, practiced transporting a tennis ball in a specified sequence within a time goal. We compared a high-involvement group (involvement yoked, IY), notified in advance about upcoming KR trials, to self-controlled KR (SC) and yoked KR (YK) groups. The experiment consisted of three phases: acquisition, retention, and transfer. We found both IY and SC groups to be superior to YK for transfer of learning. Postexperiment participant questionnaires confirmed a preference for receiving KR after learner-perceived good trials, even though performance on those trials did not differ from performance on trials without KR. Equivalent IY and SC performances provide support for the benefits of task involvement and deeper information processing when KR is self-controlled in motor skill acquisition.

    Full Text Available Many elements contribute to the relative difficulty in acquiring specific aspects of English as a foreign language (Goldschneider & DeKeyser, 2001. Modal auxiliary verbs (e.g. could, might, are examples of a structure that is difficult for many learners. Not only are they particularly complex semantically, but especially in the Malaysian context reported on in this paper, there is no direct equivalent in the students’ L1. In other words, they are a good example of a structure for which successful acquisition depends very much on the quality of the input and instruction students receive. This paper reports on analysis of a 230,000 word corpus of Malaysian English textbooks, in which it was found that the relative frequency of the modals did not match that found in native speaker corpora such as the BNC. We compared the textbook corpus with a learner corpus of Malaysian form 4 learners and found no direct relationship between frequency of presentation of target forms in the textbooks and their use by students in their writing. We also found a very large percentage of errors in students’ writing. We suggest a number of possible reasons for these findings and discuss the implications for materials developers and teachers.

    Full Text Available Reading passages contain many new words. Looking up every word in the dictionary and finding the exact meaning can be a difficult job for learners and may hinder the process of reading. Providing glosses can help learners deal with this issue. The objective of the present study is to make enquiries about the effect of glosses on incidental vocabulary learning. To this end, 45 Iranian EFL learners were selected from 70 according to their performance on KET test. Then they were divided into three groups of 15 randomly. Ten reading texts were selected and unfamiliar vocabularies were glossed in three ways: pictorial, textual and pictorial-textual glosses. Participants were required to read the texts under one of the three conditions. After the completion of ten sessions of treatment, participants were given a vocabulary post-test to measure vocabulary learning. The outcome of the study indicated that the group that received the combination of pictorial and textual glosses outperformed the other two groups. The findings can be of great importance for language teachers and material developers.

    Full Text Available Language learning has experienced a shift of focus from a form-focused to a meaning-focused approach, and the necessity of using task-based learning, a relatively recent approach, has emerged. The vital role of task-based materials makes it obligatory not to exclude them from the language learning syllabi.  The current study aims at investigating whether task-based reading can contribute significantly to the development of reading comprehension of Iranian advanced EFL learners of English. An experimental study was carried out in order to scrutinize the applicability of task-based language teaching. To this end, 60 female advanced EFL learners, selected from among a pool of 100 learners, were assigned equally and randomly into two groups of thirty, consisting of an experimental and a control group. The selection of the participants was based on the results of a standard and piloted version of Paper-based TOEFL. The participant’s mean age was about 23, ranging from 20 to 27 years of age. Both groups received a pretest and a post-test of reading. During the treatment period the experimental group received task-based reading activities while the control group received reading instructions through traditional methods. The impact of the treatment upon the reading comprehension ability of the participants was analyzed through an independent-samples t-test, and comparisons between groups were made. The results clearly indicated the development of reading comprehension ability of the participants in the first group (the experimental group through the application of task-based reading activities.

    2016-01-01

    Full Text Available Recent research and development show promising use of high-performance solid-state receivers of the electromagnetic radiation. These receivers are based on the low-barrier Schottky diodes. The approach to the design of the receivers on the basis of delta-doped low-barrier Schottky diodes with beam leads without bias is especially actively developing because for uncooled receivers of the microwave radiation these diodes have virtually no competition. The purpose of this work is to improve the main parameters and characteristics that determine the practical relevance of the receivers of mid-infrared electromagnetic radiation at the operating room temperature by modifying the electrodes configuration of the diode and optimizing the distance between them. Proposed original design solution of the integrated receiver of mid-infrared radiation on the basis of the low-barrier Schottky diodes with beam leads allows to effectively adjust its main parameters and characteristics. Simulation of the electromagnetic characteristics of the proposed receiver by using the software package HFSS with the basic algorithm of a finite element method which implemented to calculate the behavior of electromagnetic fields on an arbitrary geometry with a predetermined material properties have shown that when the inner parts of the electrodes of the low-barrier Schottky diode is performed in the concentric elliptical convex-concave shape, it can be reduce the reflection losses to -57.75 dB and the standing wave ratio to 1.003 while increasing the directivity up to 23 at a wavelength of 6.09 μm. At this time, the rounded radii of the inner parts of the anode and cathode electrodes are equal 212 nm and 318 nm respectively and the gap setting between them is 106 nm. These parameters will improve the efficiency of the developed infrared optical-promising and electronic equipment for various purposes intended for work in the mid-infrared wavelength range.

    Full Text Available : Individual learner differences play an integral role in second language acquisition and interested researchers and practitioners cannot get a full appreciation of second language learning if they ignore these significant variables. This study investigated how willingness to communicate (WTC, learner subjectivity, and anxiety in learning the L2 correlate with Iranian students’ English pragmatic knowledge. To this end, a total of 140 participants received instruction on request strategy types and their internal and external modification devices for seven weeks through consciousness-raising tasks. The data were obtained through WTC questionnaire, learner subjectivity questionnaire, foreign language classroom anxiety scale, and discourse completion test. The findings indicated that WTC and learner subjectivity correlated positively with the participants’ L2 pragmatic competence. However, no relationship was observed between the learners’ anxiety and their pragmatic achievement. The results suggest that some personal characteristics such as WTC and learner subjectivity are significant contributors to success in acquiring L2 pragmatic knowledge. چکیده: تفاوت های فردی زبان آموزان نقش غیر قابل انکاری در یادگیری زبان دوم ایفا میکنند و محققان علاقه مند نخواهند توانست به درک کامل و درستی از یادگیری زبان دوم برسند اگر چنین متغیرهای مهمی را نادیده بگیرند. این مطالعه به بررسی چگونگی ارتباط تمایل به برقراری ارتباط کلامی (WTC،  فردیت زبان آموز و اضطراب در یادگیری زبان دوم با دانش منظور شناسی زبان آموزان ایرانی می پردازد. برای این منظور، در مجموع 140 نفر در مورد انواع استراتژی های درخواست و ابزارهای

    Full Text Available Considering the overall tendency of foreign language learners to use mechanical strategies of rote rehearsal in vocabulary learning and their resistance towards use of 'deep' vocabulary learning strategies, namely contextual guessing, Keyword Method, metacognitive strategy, and semantic mapping, this study intended (a to explore what impact the instruction of these deep strategies, on vocabulary retention of 32 post-intermediate adult EFL Iranian learners, (b to determine how the variable of gender influences the vocabulary retention of students after receiving training in these strategies. To this end, on the basis of a strategy-based model of instruction–CALLA (Chamot & O'Malley, 1994, the experimental group received training in using 'deep' vocabulary learning strategies while the control group received only the common method of vocabulary teaching. After the treatment, following factorial design, the performance of the participants in the teacher-made vocabulary test as posttest was analyzed statistically.  The results indicated higher vocabulary retention for the experimental group, and it was revealed that female students were more receptive to strategy training. This study provides evidence for confirmation of 'depth of processing' hypothesis and the emerging theory about the impact of gender on effective strategy teaching and use, and it recommends incorporation of teaching these 'deep' strategies of vocabulary learning into EFL classrooms.

  16. Action towards hope: Addressing learner behaviour in a classroom

    Directory of Open Access Journals (Sweden)

    Raelene LeeFon

    2013-11-01

    Full Text Available Unruly learners and disciplinary problems are an intractable part of every teacher’s teaching experience. It appears that, even though most schools have enacted a code of conduct to regulate learner behaviour, this does not always have the desired effect. Disciplinary problems in schools impact negatively on the teaching and learning environment as well as on teachers’ personal and professional well-being and morale. Framed within the context of a biblical worldview, this article narrates the experiences of one teacher who decided to take action towards hope. The situation in her classroom was quite desperate with learners coming to school unprepared and behaving very badly and parents being uninterested in the performance of their children at school. She realised that she could not change the learners or their parents unless she started with herself. In this context, she, as a postgraduate student under the supervision of the co-authors, embarked on an action-research project to promote positive learner behaviour. By collaborating with the learners on a set of classroom rules, engaging in reflective teaching and changing her own behaviour towards the learners, the situation in her classroom improved. Based on her experiences, this article argues that teachers should empower themselves with knowledge and a better understanding of the concept of discipline rather than viewing the classroom as a battlefield. It is important to acknowledge and show respect and appreciation for each learner in his or her own context.

    2017-11-01

    Full Text Available This survey provides an overview of implemented systems, theoretical work, as well as studies of biological systems relevant to the design of artificial learners trying to figure out what a human teacher would like them to do. Implementations of artificial learners are covered, with a focus on experiments trying to find better interpretations of human behavior, as well as algorithms that autonomously improve a model of the teacher. A distinction is made between learners trying to interpret teacher behavior in order to learn what the teacher would like the learner to do on the one hand, and learners whose explicit or implicit goal is to get something from the teacher on the other hand (for example rewards, or knowledge about how the world works. The survey covers the former type of systems. Human teachers are covered, focusing on studies that say something concrete about how one should interpret the behavior of a human teacher that is interacting with an artificial learner. Certain types of biological learners are interesting as inspiration for the types of artificial systems we are concerned with. The survey focus on studies of biological learners adopting normative conventions, as well as joint intentionality team efforts.

Both learning difficulty and learner identity are viewed as being constructed in discursive interactions throughout one's life and, hence, amenable to reconstruction. Data collected from classroom interactions,…

    A description of the general design of both the block 3 and block 4 receiver-exciter controllers for the Deep Space Network (DSN) Mark IV-A System is presented along with the design approach. The controllers are designed to enable the receiver-exciter subsystem (RCV) to be configured, calibrated, initialized and operated from a central location via high level instructions. The RECs are designed to be operated under the control of the DMC subsystem. The instructions are in the form of standard subsystem blocks (SSBs) received via the local area network (LAN). The centralized control provided by RECs and other DSCC controllers in Mark IV-A is intended to reduce DSN operations costs from the Mark III era.

    Full Text Available Metacognitive strategy instruction (MetSI has been shown to have a strong impact on various aspects of English as a second/foreign language instruction. The present study aimed to investigate the effect of MetSI on the improvement of listening selfefficacy among English-as-a-foreign-language (EFL learners. A group of sixty female undergraduate learners of English literature at a state-run university in Iran consented to take part in this study. After homogenizing the participants' English proficiency level using a sample section of the British Council IELTS test, 40 learners were selected whose English proficiency fell within intermediate to upperintermediate level. A listening self-efficacy questionnaire (borrowed from Rahimi and Abedini, 2009 was used to measure the participants’ level of listening selfefficacy in the pre and post-test phases of the study. The participants were randomly assigned to treatment (n=20 and control (n=20 groups. The treatment group received 8 hours of MetSI during eight sessions based on the model proposed by Vandergrift (2003 while the control group didn't receive any explicit MetSI. The control group received the usual training in listening instead.

    In this paper we discuss the stability of heterodyne terahertz receivers based on small volume NbN phonon cooled hot electron bolometers (HEBs). The stability of these receivers can be broken down in two parts: the intrinsic stability of the HEB mixer and the stability of the local oscillator (LO) signal injection scheme. Measurements show that the HEB mixer stability is limited by gain fluctuations with a 1/f spectral distribution. In a 60 MHz noise bandwidth this results in an Allan varian...

  2. Course-embedded student support for online English language learners

    Directory of Open Access Journals (Sweden)

    Maureen Andrade

    2014-02-01

    Full Text Available This paper describes an embedded approach to learner support in online English language courses. The support model is based on language acquisition, transactional distance, and self-regulated learning theories. Based on these theories, courses were designed to provide the interaction necessary for academic English language gains, decrease the transactional distance between the teacher and learner, and assist learners in developing the ability to control the factors that affect their learning; in other words, to be self-regulated learners. The latter is critical for those who lack the autonomy needed for successful distance learning. In this paper, three course activities are described and analyzed to demonstrate how the embedded support model responds to the needs of diverse learners and assists them in achieving identified outcomes. The courses were designed for off-site international students enrolled in traditional English-speaking higher education institutions.http://dx.doi.org/10.5944/openpraxis.6.1.90

    2012-10-01

    Full Text Available Affective learner factors were first considered as a cause of success in language learning. This was followed by a change in approach and recently authors (e.g., Edelenbos, Johnstone, & Kubanek, 2006 have considered them an important outcome, especially in early foreign language learning (FLL. Current research into affective learner factors in early FLL tries to catch the developmental aspects too, and studies are emerging that take a contextual view as well. This paper describes a study on affective characteristics of young FL learners that combines the developmental and contextual perspectives. Using the case study methodology the author analyses the affective profiles of three young learners of English as a foreign language who were followed for 4 years. The analyses are done taking into account their immediate language learning environment, home support, out-of-school exposure to English and language achievement. The findings suggest that affective learner factors contribute to the dynamic complexity of early FLL.

    To investigate the relationship between the advantage ear (cerebral hemisphere) of Spanish-speaking Mexican learners and the third Chinese tone. Third tone Chinese vowel syllables were used as experimental materials with dichotic listening technology to test the Spanish-speaking Mexican Chinese learners (20-32 years old) who studied Chinese about 20 h. In terms of error rates to identify the third Chinese tone, the Spanish-speaking Mexican Chinese learners's reaction to the third tone suggested that their left ears were the advantageous ear (the right cerebral hemisphere) (Z=-2.091, P=0.036). The verbal information of tones influenced the perception of Mexican Chinese learners' mandarin tones. In the process of learning mandarin tones, Mexican Chinese learners gradually formed the category of tones.

We hypothesized that a pre-training intervention providing a generalized schema as a structuring framework for such knowledge in pieces would support (reorganizing-processes of prior knowledge and thus reduce unnecessary cognitive load during subsequent learning. Fifty-six student teachers participated in the experiment. A framework group underwent a pre-training intervention providing a generalized, categorical schema for categorizing primary learning strategies and related but different strategies as a cognitive framework for (re-organizing their prior knowledge. Our control group received comparable factual information but no framework. Afterwards, all participants learned about primary learning strategies. The framework group claimed to possess higher levels of interest and self-efficacy, achieved higher learning outcomes, and learned more efficiently. Hence, providing a categorical framework can help overcome the barrier of incorrect prior knowledge in pieces.

    Highlights: • A 93.7 m long EuBCO + BHO CC with 103 A/cm W at 77 K under 3 T was obtained. • The 93.7 m long CC showed high I_c values and high n-values with high uniformity. • The average I_c value at 77 K under 3 T was estimated by that at 77 K under 0.3 T. - Abstract: Introduction of artificial pinning centers such as BaHfO_3 (BHO), BaZrO_3 (BZO) and BaSnO_3 (BSO) into REBa_2Cu_3O_7_−_δ (REBCO) coated conductor (CC) layers could improve the in-field critical currents (I_c) in wide ranges of temperatures and magnetic fields. In particular, a combination of EuBCO + BHO has been found to be effective for attaining high in-field I_c performance by means of IBAD/PLD process in short length samples. In this work, we have successfully fabricated a 93.7 m long EuBCO + BHO CC with 103 A/cm W at 77 K under a magnet field (B) of 3 T applied perpendicular to the CC (B//c). The 93.7 m long EuBCO + BHO CC had high uniformity of I_c values and n-values without any trend of fluctuations, independent of the external field up to 0.3 T. I_c–B–applied angle (θ) profiles of the 93.7 m long EuBCO + BHO CC sample showed the high in-field I_c values in all directions of applied magnetic fields especially B//c (at θ ∼ 180°, I_c = 157 A/cm W) at 77 K under 3 T. The profiles were about the same as those in a short length sample.

  8. AES, EELS and XPS characterization of Ti(C, N, O) films prepared by PLD using a Ti target in N2, CH4, O2 and CO as reactive gases

    International Nuclear Information System (INIS)

    Soto, G.

    2004-01-01

    Titanium-based films were grown on (1 0 0)-Si substrates by the pulsed laser deposition (PLD) method using a Ti target in reactive atmospheres. The films were grown in vacuum (Ti-film), O 2 (TiO x ), N 2 (TiN x ), CH 4 (TiC x ), CO (TiC x O y ), N 2 +CH 4 (TiC x N y ) and CO+N 2 (TiC x N y O z ). After depositions, every film is characterized in situ by Auger, electron-energy loss and X-ray photoelectron (XPS) spectroscopies. For the binary compounds the stoichiometry is regulated without difficulty by gas pressure during ablation. However, for ternary and quaternary compounds there is a tendency to produce chemically inhomogeneous films. For example, the ablation of Ti in a N 2 +CH 4 environment results in a TiNC:C composite. In this case, the overabundance of nitrogen influences the segregation of carbon. In the other hand, the O 2 +CH 4 mixture was ineffectively to produce TiC x O y films, yielding mostly TiO 2 with traces of embedded carbon. By using CO as reactive gas the TiC x O y films were completed. Also, a mixture of CO with N 2 was tested to produce quaternary TiC x N y O z compounds. Based on these results, it is recommended that better control on film stoichiometry and chemical homogeneity can be achieved by using reactive gases with predetermined C:N:O ratios

    Full Text Available This chapter focuses on the development of young learners’ ability to communicate in a foreign language. An empirical study was carried out to determine whether, after four years of learning English as a compulsory school subject, children are ready to engage in oral interaction in a semicontrolled task and produce answers and questions in English. A convenience sample of ten-year-old children was selected from 180 participants in ELLiE2 in Poland. Six learners from one class of each of seven schools were selected on the basis of teachers’ reports to ensure equal proportions of learners with low, medium and high ability. Schools were chosen to represent different socio-economic milieux. The results of the Year Four oral test (an interactive task showed that almost all the participating childrencould respond to questions but only half were able to ask questions.Considering generally positive attitudes to speaking activities, the results suggest that ten-year-old children are already developing their interactive skills and could benefit from more interaction-focused classroom activities. Further experimental classroom-based studies are necessary to gain better insight into potential oral achievements in this age group. The results are discussed in the context of national curriculum requirements, drawing on the Common European Framework of Reference level descriptors.

    Dilek ALTUNAY

    2013-10-01

    Full Text Available This study investigates the noncompulsory language learning activities performed by a group of distance EFL learners in the Turkish Open Education System. Performance of these activities has been considered as an indicator of their learner autonomy. The data were collected through an online questionnaire and interviews. The study shows that in general learners do not demonstrate autonomous language learning behaviour. They prefer learning English in a relaxed environment particularly by engaging in entertaining activities, and through note-taking. However, they do not have sufficient interaction with their facilitator, other learners or speakers. Although the participants are distance learners, they do not prefer Internet-based activities. Conditions stemming from adulthood, lack of skills necessary to perform an activity, lack of awareness of some activities and learners’ experiences in their previous years of education are some of the reasons for their unautonomous behaviour. The article also includes suggestions for teaching and future research.

    Full Text Available Japanese language learners aim to acquire reading, listening, writing and speaking skills. We at the Hinoki project (https://hinoki-project.org/ have recently been working on the Natsume collocation search system (https://hinoki-project.org/natsume/, the Natane learner corpus to support Natsume (https://hinoki-project.org/natane/ and the Nutmeg writing support system (http://hinoki-project.org/nutmeg/. In order to test the effectiveness of Nutmeg, we conducted an online experiment with 36 participants who used the system's register misuse identification feature to correct four writing assignments. Results show that Nutmeg can be an effective tool in correcting common register-related errors, especially those involving auxiliary verbs. However, the accuracy of verb and adverb identification was too low, suggesting the need for improvements in the variety of corpora used for identifying register misuse.

    An optical correlation receiver is described that provides ultra-precise distance and/or time/pulse-width measurements even for weak (single photons) and short (femtosecond) optical signals. A new type of optical correlation receiver uses a fourth-order (intensity) interferometer to provide micron distance measurements even for weak (single photons) and short (femtosecond) optical signals. The optical correlator uses a low-noise-integrating detector that can resolve photon number. The correlation (range as a function of path delay) is calculated from the variance of the photon number of the difference of the optical signals on the two detectors. Our preliminary proof-of principle data (using a short-pulse diode laser transmitter) demonstrates tens of microns precision.

    CommLargo, Inc., has developed a scintillation-hardened Global Positioning System (GPS) receiver that improves reliability for low-orbit missions and complies with NASA's Space Telecommunications Radio System (STRS) architecture standards. A software-defined radio (SDR) implementation allows a single hardware element to function as either a conventional radio or as a GPS receiver, providing backup and redundancy for platforms such as the International Space Station (ISS) and high-value remote sensing platforms. The innovation's flexible SDR implementation reduces cost, weight, and power requirements. Scintillation hardening improves mission reliability and variability. In Phase I, CommLargo refactored an open-source GPS software package with Kalman filter-based tracking loops to improve performance during scintillation and also demonstrated improved navigation during a geomagnetic storm. In Phase II, the company generated a new field-programmable gate array (FPGA)-based GPS waveform to demonstrate on NASA's Space Communication and Navigation (SCaN) test bed.

    As an international language, English is taught and learnt by almost all of the people in the world. In Indonesia for example, English has been introduced since the learners are studying at the elementary school. Even many of the Kindergarten Schools too, have already introduced this language to their students. However, we cannot deny that teaching foreign language is not such an easy thing due to the fact thatmany of the learners are not capable of speaking English very well although they have been learning it for more than ten years (Elementary: 6 years, Junior and Senior High School: 6 years). In line with this problem, this study aims at providing a solution by offering one teaching technique which seems to make the learners (especially young learners) enjoy learning through singing songs (Kasihani, 1999).Furthermore, Phillips(1995) said that young learners really enjoyed learning and singing songs with highly motivating. Based on those two researches andin efforts to make it easier in English language learning, especially to young learners, the writer translated the very common and popular Indonesian kid songs into English. Thesetranslated songswere then used to teach the students of Kindergarten up to Elementary ones of the first and second grade. This meant that before a teacher started to teach, s/he had to translate the Indonesian kid songsat first into English.Due to its popularity and familiarity, it was expected that this teaching technique would be more effective and efficient to apply especially to young learners.

  3. Cognitive Load Theory and the Use of Worked Examples as an Instructional Strategy in Physics for Distance Learners: A Preliminary Study

    Directory of Open Access Journals (Sweden)

    Kim Guan SAW

    2017-10-01

    Full Text Available This article revisits the cognitive load theory to explore the use of worked examples to teach a selected topic in a higher level undergraduate physics course for distance learners at the School of Distance Education, Universiti Sains Malaysia. With a break of several years from receiving formal education and having only minimum science background, distance learners need an appropriate instructional strategy for courses that require complex conceptualization and mathematical manipulations. As the working memory is limited, distance learners need to acquire domain specific knowledge in stages to lessen cognitive load. This article charts a learning task with a lower cognitive load to teach Fermi-Dirac distribution and demonstrates the use of sequential worked examples. Content taught in stages using worked examples can be presented as a form of didactic conversation to reduce transactional distance. This instructional strategy can be applied to similar challenging topics in other well-structured domains in a distance learning environment.

    Full Text Available This research article reports the results of a study designed to measure and analyse Spanish students' perceived anxiety when learning and using EFL inside the classroom. This article first includes a review of the literature on foreign language anxiety. Then it describes the participants of the investigation and the research methodology procedures. This is followed by the presentation and discussion of the results and, finally, the conclusions derived from this study. The resulting data revealed interesting information about the anxiety levels present among Spanish EFL learners. While relatively high levels of speaking anxiety have been identified, somewhat lower levels of listening anxiety associated with error correction, by contrast, have also been found. More specifically, the results suggested that the level of listening anxiety seems to slightly increase when error correction is somehow involved in the process.

    Metacognition is an essential skill in critical thinking and self-regulated, lifelong learning. It is important for learners to have skills in metacognition because they are used to monitor and regulate reasoning, comprehension, and problem-solving, which are fundamental components/outcomes of pharmacy curricula. Instructors can help learners develop metacognitive skills within the classroom and experiential setting by carefully designing learning activities within courses and the curriculum. These skills are developed through intentional questioning, modeling techniques, and reflection. This article discusses key background literature on metacognition and identifies specific methods and strategies to develop learners' metacognitive skills in both the classroom and experiential settings.

  11. Solar receiver with integrated optics

    Science.gov (United States)

    Jiang, Lun; Winston, Roland

    2012-10-01

    The current challenge for PV/Thermal (PV/T) systems is the reduction of radiation heat loss. Compared to solar thermal selective coating, the solar cells cannot be used as an efficient thermal absorber due to their large emissivity of the encapsulation material. Many commercial PV/T products therefore require a high concentration (more than 10x) to reach an acceptable thermal efficiency for their receivers. Such a concentration system inevitably has to track or semi-track, which induces additional cost and collects only the direct radiation from the sun. We propose a new PV/T design using a vacuum encapsulated thin film cell to solve this problem. The proposed design also collects the diffuse sun light efficiently by using an external compound parabolic concentrator (XCPC). Since the transparent electrode (TCO) of thin film cell is inherently transparent in visible light and reflective beyond infrared, this design uses this layer instead of the conventional solar cell encapsulation as the outmost heat loss surface. By integrating such a vacuum design with a tube shaped absorber, we reduce the complexity of conducting the heat energy and electricity out of the device. A low concentration standalone non-tracking solar collector is proposed in this paper. We also analyzed the thermosyphon system configuration using heat transfer and ray tracing models. The economics of such a receiver are presented.

    Jamin, Olivier

    2014-01-01

    This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains.  A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis.  Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm...

  2. Supporting learner-centered technology integration through situated mentoring

    Science.gov (United States)

    Rosenberg, Marian Goode

    Situated mentoring was used as a professional development method to help 11 high school science teachers integrate learner-centered technology. The teachers' learner-centered technology beliefs and practices as well as their perception of barriers to learner-centered technology integration were explored before and after participating in the mentoring program. In addition, the participants' thoughts about the effectiveness of various components of the mentoring program were analyzed along with the mentor's observations of their practices. Situated mentoring can be effective for supporting learner-centered technology integration, in particular decreasing the barriers teachers experience. Goal setting, collaborative planning, reflection, and onsite just-in-time support were thought to be the most valuable components of the mentoring program.

  3. Using music activities to enhance the listening skills and language skills of Grade 1, English first additional language learners

    Directory of Open Access Journals (Sweden)

    Hugo, Anna J.

    2013-12-01

    Full Text Available Music activities can be used to develop and enhance young learners’ listening abilities. Listening is a language skill which is a prerequisite for the development of other language skills and especially for the development of a person’s speaking abilities. It is also a prerequisite for the development of a person’s language abilities in a second language. In a research project involving a group of 70 English first additional language learners, two Grade 1 classes were selected. One class was the experimental group and the other class was the comparison group. Over a period of six months the experimental group received planned music activities daily. When the two groups were retested after six months, significant differences in the means between the experimental and the control groups were found. The experimental group significantly improved their listening skills in English as a second language (ESL. This has implications for teaching ESL learners in the Foundation Phase.

  4. Elderly Learners and Massive Open Online Courses: A Review.

    Science.gov (United States)

    Liyanagunawardena, Tharindu Rekha; Williams, Shirley Ann

    2016-01-07

    Massive open online courses (MOOCs) have become commonplace in the e-learning landscape. Thousands of elderly learners are participating in courses offered by various institutions on a multitude of platforms in many different languages. However, there is very little research into understanding elderly learners in MOOCs. We aim to show that a considerable proportion of elderly learners are participating in MOOCs and that there is a lack of research in this area. We hope this assertion of the wide gap in research on elderly learners in MOOCs will pave the way for more research in this area. Pre-course survey data for 10 University of Reading courses on the FutureLearn platform were analyzed to show the level of participation of elderly learners in MOOCs. Two MOOC aggregator sites (Class Central and MOOC List) were consulted to gather data on MOOC offerings that include topics relating to aging. In parallel, a selected set of MOOC platform catalogues, along with a recently published review on health and medicine-related MOOCs, were searched to find courses relating to aging. A systematic literature search was then employed to identify research articles on elderly learners in MOOCs. The 10 courses reviewed had a considerable proportion of elderly learners participating in them. For the over-66 age group, this varied from 0.5% (on the course "Managing people") to 16.3% (on the course "Our changing climate"), while for the over-56 age group it ranged from 3.0% (on "A beginners guide to writing in English") to 39.5% (on "Heart health"). Only six MOOCs were found to include topics related to aging: three were on the Coursera platform, two on the FutureLearn platform, and one on the Open2Study platform. Just three scholarly articles relating to MOOCs and elderly learners were retrieved from the literature search. This review presents evidence to suggest that elderly learners are already participating in MOOCs. Despite this, there has been very little research into their

  18. Evaluating Learner Autonomy: A Dynamic Model with Descriptors

    Directory of Open Access Journals (Sweden)

    Maria Giovanna Tassinari

    2012-03-01

    Full Text Available Every autonomous learning process should entail an evaluation of the learner’s competencies for autonomy. The dynamic model of learner autonomy described in this paper is a tool designed in order to support the self-assessment and evaluation of learning competencies and to help both learners and advisors to focus on relevant aspects of the learning process. The dynamic model accounts for cognitive, metacognitive, action-oriented and affective components of learner autonomy and provides descriptors of learners’ attitudes, competencies and behaviors. It is dynamic in order to allow learners to focus on their own needs and goals.The model (http://www.sprachenzentrum.fuberlin.de/v/autonomiemodell/index.html has been validated in several workshops with experts at the Université Nancy 2, France and at the Freie Universität Berlin, Germany and tested by students, advisors and teachers. It is currently used at the Centre for Independent Language Learning at the Freie Universität Berlin for language advising. Learners can freely choose the components they would like to assess themselves in. Their assessment is then discussed in an advising session, where the learner and the advisor can compare their perspectives, focus on single aspects of the leaning process and set goals for further learning. The students’ feedback gathered in my PhD investigation shows that they are able to benefit from this evaluation; their awareness, self-reflection and decision-making in the autonomous learning process improved.

  19. Relational aggression: the voices of primary school learners

    Directory of Open Access Journals (Sweden)

    Johan Botha

    2014-06-01

    Full Text Available The aim of this research was to explore and describe primary school learners' experiences of relational aggression at school. This was done within a qualitative research design with a phenomenological approach. In order to give a voice to primary school learners' lived experiences of relational aggression, 25 individual interviews were conducted with a purposeful sample of learners from two primary schools in the Dr Kenneth Kaunda District, North-West Province. Data analysis was done using Tesch's systematic open coding process. Social Learning Theory underscored the theoretical foundation that emphasises relational aggression as a socially learned phenomenon through observation. Although existing theory supports the findings, the reality, however, is that the effects of relational aggression impede negatively on learners' social and academic development and well-being. This jeopardises schools' endeavours to effectively socialise learners in order to establish and maintain effective personal and social relationships. Curtailing relational aggression has the possibility of reducing other forms of aggression in schools and will enhance the creation of effective teaching-learning environments that are conducive to teaching and learning that will support the task of schooling, which is the socialisation of learners to optimally achieve their potential in schools. The article provides some suggestions to assist teachers in endeavours to effectively curtail relational aggression.

  20. Highly scalable and robust rule learner: performance evaluation and comparison.

    2006-02-01

    Business intelligence and bioinformatics applications increasingly require the mining of datasets consisting of millions of data points, or crafting real-time enterprise-level decision support systems for large corporations and drug companies. In all cases, there needs to be an underlying data mining system, and this mining system must be highly scalable. To this end, we describe a new rule learner called DataSqueezer. The learner belongs to the family of inductive supervised rule extraction algorithms. DataSqueezer is a simple, greedy, rule builder that generates a set of production rules from labeled input data. In spite of its relative simplicity, DataSqueezer is a very effective learner. The rules generated by the algorithm are compact, comprehensible, and have accuracy comparable to rules generated by other state-of-the-art rule extraction algorithms. The main advantages of DataSqueezer are very high efficiency, and missing data resistance. DataSqueezer exhibits log-linear asymptotic complexity with the number of training examples, and it is faster than other state-of-the-art rule learners. The learner is also robust to large quantities of missing data, as verified by extensive experimental comparison with the other learners. DataSqueezer is thus well suited to modern data mining and business intelligence tasks, which commonly involve huge datasets with a large fraction of missing data.

    Manssour Habbash

    2016-04-01

    Full Text Available In view of the increasing concern among English language teachers dealing with students from Saudi Arabia, as it manifests in TESOL community discussions, about the uniqueness of Saudi Arabian EFL learners, this paper attempts to document the outcome of a study of their distinctiveness from the perspective of expatriate teachers working for PYPs (Preparatory Year Programs in Saudi Arabia. This study examines the distinctiveness with regard to the learning attitudes of Saudi students that are often cultivated by the culture and academic environment in their homeland. Employing an emic approach for collecting the required data an analysis was carried out in light of the other studies on ‘education’ in Saudi Arabia that have particular reference to the factors that can positively influence student motivation, student success and the academic environment. The findings were used in constructing the rationale behind such distinctiveness. Assuming that the outcome of the discussion on the findings of this exploration can be helpful for teachers in adapting their teaching methodology and improving their teacher efficacy in dealing with students both from the kingdom and in the kingdom, some recommendations are made.

    Full Text Available Background. Interprofessional education aims to prepare learners to collaborate across specialties to provide high-quality healthcare. Internationally and nationally, the emerging need for integrated healthcare and education has been emphasised. The current education programme at the School of Health Care Sciences, University of Pretoria, South Africa primarily follows a uniprofessional approach.Objectives. To describe the development of interprofessional modules over 4 years between the departments of Human Nutrition, Nursing Science, Occupational Therapy, Physiotherapy and Radiography.Methods. The Knowledge-to-Action model guided the module development process. The planning phase comprised three steps: (i problem identification (e.g. national and international policy focus on interprofessional education; (ii review of existing knowledge (e.g. common learning outcomes; and (iii adaptation of knowledge to the local context (e.g. syllabi and logistics.Results. The development of interprofessional modules can be guided by the above-mentioned model to meet the needs of the faculty, departments, students and community and to contribute to interprofessional education, while overcoming the associated challenges.Conclusion. Challenges included clashes in timetable schedules, financial constraints, administrative support, logistical issues and resistance to change. The designing and implementing of new modules were intense and time consuming, and required commitment. The development of the modules was an excellent example of interprofessional teamwork that needs to be transferred to the implementation and role modelling of interprofessional education.

    Full Text Available Playing digital games is undeniably a popular leisure activity, and digital gaming is also gaining academic attention and recognition for enhancing digital literacies and learning motivation. One tricky issue when exploring digital gaming in Asian contexts is the popularity of English and Japanese games. Though Chinese and Korean online games are readily available, many of the more popular commercial off-the-shelf (COTS digital games are in English and Japanese. Students in Hong Kong are required to take English as a foreign language, which resulted in a huge range of proficiency, but Japanese is not offered at public schools. So, most Hong Kong gamers are playing foreign language games. Yet language barriers do not diminish the market demand for foreign language digital games. This paper explores the phenomenon of digital gaming in foreign languages. Based on findings from an on-going research project with ten undergraduate video gamers (F=4, M=6, this paper argues that gamers exercise learner autonomy by managing their gaming both as leisure and learning experiences.

Through negotiation with system, the editable learner model will be updated to support adaptive engine to select adaptive contents meeting learner's demands. Empirical testing results for students who used application prototype indicate that interaction user modeling is helpful in supporting learner to learn adaptive materials.

  7. Learner-centred medical education: Improved learning or increased stress?

    Science.gov (United States)

    McLean, Michelle; Gibbs, Trevor J

    2009-12-01

    Globally, as medical education undergoes significant reform towards more "learner-centred" approaches, specific implications arise for medical educators and learners. Although this learner-centredness is grounded in educational theory, a point of discussion would be whether the application and practice of these new curricula alleviate or exacerbate student difficulties and levels of stress. This commentary will argue that while this reform in medical education is laudable, with positive implications for learning, medical educators may not have understood or perhaps not embraced "learner-centredness" in its entirety. During their training, medical students are expected to be "patient-centred". They are asked to apply a biopsychosocial model, which takes cognisance of all aspects of a patient's well-being. While many medical schools profess that their curricula reflect these principles, in reality, many may not always practice what they preach. Medical training all too often remains grounded in the biomedical model, with the cognitive domain overshadowing the psychosocial development and needs of learners. Entrusted by parents and society with the education and training of future healthcare professionals, medical education needs to move to a "learner-centred philosophy", in which the "whole" student is acknowledged. As undergraduate and post-graduate students increasingly apply their skills in an international arena, this learner-centredness should equally encapsulate the gender, cultural and religious diversity of both patients and students. Appropriate support structures, role models and faculty development are required to develop skills, attitudes and professional behaviour that will allow our graduates to become caring and sensitive healthcare providers.

    Grounded in Hallidayan perspectives on academic language, we report on our development of an educative science assessment as one component of the language-rich inquiry science for English-language learners teacher professional learning project for middle school science teachers. The project emphasizes the role of content-area writing to support teachers in diagnosing their students' emergent understandings of science inquiry practices, science content knowledge, and the academic language of science, with a particular focus on the needs of English-language learners. In our current school policy context, writing for meaningful purposes has received decreased attention as teachers struggle to cover large numbers of discrete content standards. Additionally, high-stakes assessments presented in multiple-choice format have become the definitive measure of student science learning, further de-emphasizing the value of academic writing for developing and expressing understanding. To counter these trends, we examine the implementation of educative assessment materials—writing-rich assessments designed to support teachers' instructional decision making. We report on the qualities of our educative assessment that supported teachers in diagnosing their students' emergent understandings, and how teacher-researcher collaborative scoring sessions and interpretation of assessment results led to changes in teachers' instructional decision making to better support students in expressing their scientific understandings. We conclude with implications of this work for theory, research, and practice.

    Full Text Available The purpose of the present study was to explore the effects of using podcast on listening comprehension among Iranian pre-intermediate EFL learners. To fulfill the objectives of the study a Homogeneity test (Oxford Quick Placement Test was administered among 90 students at the pre-intermediate level of Poyesh language Institute and finally 60 participants were selected. Then, they were non-randomly divided into two sub­groups, namely control and experimental groups.  Before starting the treatment, a validated teacher-made listening comprehension test was administered to students as pre-test to assess the participants' listening comprehension at the beginning of the course. Then, the experimental group received the treatment, which was teaching listening comprehension through using podcasts while the control group was taught using traditional methods of teaching listening with no multimedia source. After 20 sessions of treatment, the two groups were administered the same teacher-made listening test as post-test. Data were analyzed by Paired and Independent Samples t-­test. The findings showed that the experimental group significantly performed better than the control group. Generally, the experimental groups outperformed the control groups. The results suggest that podcasts can be used in English classes to develop listening ability among Iranian EFL learners.

    The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.

    Full Text Available The Doctoral Community Network (DC is a learner driven, scholarly community designed to help online doctoral learners successfully complete their dissertation and program of study. While digital natives grew up in an environment immersed in technology, digital immigrants adapted to this environment through their ability to learn and adjust to new technologies. With several thousand Doctoral Community Network users, it was not known to what extent digital immigrants had embraced the technology. A study of 988 users determined that digital immigrants used the Doctoral Community Network more often and for a larger variety of purposes than digital natives did. Specifically, digital immigrants log-on more frequently, view leadership content at higher rates, read more blogs, use more doctoral community network research resources, and send and receive more peer messages than digital natives do. This research supports existing literature that found that digital immigrants possess higher levels of social reliance than digital natives while contradicting other literature that found that digital natives tend to use the internet for social networking and blog diaries at higher rates.

    Full Text Available This study investigates the challenges faced by Arab adult learners of English as a foreign language (EFL in acquiring English restrictive relative clauses (RRCs, as well as the factors that affect the process of acquisition. This issue has received considerable attention in second language (L2 research. The present study discusses the syntactic structure of RRCs in English and Arabic with regard to the use of resumptive pronouns and the use of overt versus covert relative markers as related to the definiteness of the head noun. This study is carried out using an acceptability judgment test as the tool for data collection. A sample of 100 male and female adult Arabic speakers is used with the aim of identifying potential acquisition problems. The results obtained provide further support for first language (L1 transfer. This study concludes that participants accepted the use of resumptive pronouns and preferred the overt relative markers determined by definiteness. It is further discovered that certain factors influenced the acquisition process such as participants’ age, age of learning, and age of immersion. The current study has some pedagogical implications for the teaching of relative clauses in the EFL context.

    Full Text Available This paper explores complexities and constraints affecting performance and output of physical science learners in Vhembe District, Limpopo Province, South Africa. The study was motivated by the desire of the researcher to establish, profile and characterise the complexities and constraints reminiscence of poor performance of learners in physical science as measured through end-of-year Grade 12 (final year of high school education examination results. Twenty six schools (n=26 were purposively selected from three circuits of education (n=3. From these schools, two learners were randomly selected (n=52 for interviews. In addition, two circuit managers (n=2 were conveniently selected as part of Key Informant Interviews (KII. For the Focus Group Discussions (FGDs, twelve (n=12 parents were randomly selected to form two groups of six members each. Multi-factor complexities and constraints impeding performance of learners were discovered. Intensive teacher in-service programme is recommended. Community engagement should be encouraged to educate parents on the value of involvement in the education of their children. Free access learner support structures such as Homework and Extra-lessons Assistance Centre (H&EACs should be established.

    Full Text Available I examine how teachers employ a questioning strategy in supporting Grade 9 learners doing science investigations in South African schools. A particular focus of this study was how teachers use questioning in contributing towards the autonomy of these learners. The research adopted a qualitative approach which involved the collection of data by means of classroom observations and interviews with five teachers at schools resourced for practical work. The analysis of transcript data revealed that teachers support learners by asking probing questions at all stages of the investigation. The teachers used a questioning strategy in enabling the learners to understand more clearly the question or hypothesis they intended investigating, to review and reconsider their planning, to rethink some of their actions when collecting data, to make sense of their data, and to revisit and amend their plan after generating incorrect findings. The significance of this study, in making explicit teacher questioning at the stages of the investigation, is that it provides a guideline for teachers on how to support learners attain greater autonomy in doing science investigations.

    Research on metacognition has consistently demonstrated that learners fail to endorse instructional designs that produce benefits to memory, and often prefer designs that actually impair comprehension. Unlike previous studies in which learners were only exposed to a single multimedia design, the current study used a within-subjects approach to examine whether exposure to both redundant text and non-redundant text multimedia presentations improved learners' metacognitive judgments about presentation styles that promote better understanding. A redundant text multimedia presentation containing narration paired with verbatim on-screen text (Redundant) was contrasted with two non-redundant text multimedia presentations: (1) narration paired with images and minimal text (Complementary) or (2) narration paired with minimal text (Sparse). Learners watched presentation pairs of either Redundant + Complementary, or Redundant + Sparse. Results demonstrate that Complementary and Sparse presentations produced highest overall performance on the final comprehension assessment, but the Redundant presentation produced highest perceived understanding and engagement ratings. These findings suggest that learners misperceive the benefits of redundant text, even after direct exposure to a non-redundant, effective presentation.

    Full Text Available Listening skill has been recently paid great attention comparing with the other three language skills since having communication is the first and most essential need. Language learners have been using the three different listening strategies (Cognitive, Meta-cognitive, and Socio-affective to improve their listening skills in multimedia environments in particular. The main focus of this study is to determine the most preferable listening strategies employed in improving listening skills in multimedia environment by female Iranian English language learners. To achieve the goals, thirty female English language learners – twenty to twenty five - out of sixty were selected. In order to collect data IELTS test as pre-test and post-test questionnaire and interview were used. The result indicated that these language learners mainly employed meta-cognitive strategies the most in the multimedia environment. Thus, it is implied that the findings would be beneficial to the classroom practice, guide learners and lecturers as well as syllabus planners and material designers

    Full Text Available Although our ultimate goal is to enable our learners to become autonomous and efficient in their use of the foreign language, whether or not they have the opportunity to ever live and interact in a foreign language setting, our work as teachers must involve a conscious analysis of the different factors involved in this process, as well as the conscious effort to put all the intervening factors into action. Furthermore, it is our responsibility to develop the learners¿ thinking skills as they increase their competence in the target language and at the same time make them aware of their responsibility for their own processes and success by enhancing their autonomy and making them aware of the value of learning strategies. It is our task as teachers to be present on this journey and guide our learners towards becoming architects and masters of their own foreign language construct. In order for this journey to be a successful one, we must make sure we provide the learner with a correct supply of building blocks. In this paper we present an analysis of the main components comprised in teaching English as a foreign language, including a historical overview of methods, approaches, strategies, the concept of learner¿s autonomy, social and psychological factors, aiming at contributing to every teacher¿s reflection on his/her task in the school context.

    Full Text Available This study builds on the instructional effectiveness and efficiency of two game approaches on word spelling of EFL beginners. The approaches under study were cooperative approach and individualistic approach. The participants of this study consisted of 59 fifth and sixth grade students from two elementary schools in the same district in Firoozeh, Neyshabur- Iran. They received 90 minutes instruction per week for a total of ten sessions in two groups of cooperative and individualistic. The results of the study indicated that there is not a significant difference between the performance of learners in cooperative and individualistic groups. A questionnaire was also given to the learners at the end in order to measure learners' attitude toward the games. The results showed that there is not a big difference between students' attitude toward learning spelling in cooperative group and individualistic group, and both groups have positive attitude toward the games. The researcher concluded that the combination of these two approaches seems more favorable.

    Full Text Available This study was an attempt to investigate the effect of two types of learning, competitive and cooperative, on the reading comprehension of introvert and extrovert EFL learners. To this end, 120 learners studying at Marefat English Language Institute in Tehran, Iran were selected, after taking a Preliminary English Test (PET, to participate in this quasi-experimental research. The participants  also answered the Eysenck Personality Inventory (EPI to categorize them into two personality types of introverts and extroverts. Therefore, there were four subgroups: 30 introverts and 30 extroverts undergoing the cooperative learning treatment, and 30 introverts and 30 extroverts experiencing the competitive learning treatment. The reading part of the PET was administered as the posttest of the study after each group was exposed to the treatment for 18 sessions in seven weeks. A two-way ANOVA was run on the collected data in the posttest of four groups. The results revealed that while learners generally outperformed in the competitive setting compared to the cooperative one, the extrovert was better off receiving cooperative instruction. Moreover, introverts excelled extroverts in the competitive group. However, there was no difference between the two personality groups in the cooperative situation.
