    The risk of developing adverse side effects in the normal tissue after radiotherapy is often limiting for the dose that can be applied to the tumor. Proton minibeam radiotherapy, a spatially fractionated radiotherapy method using sub-millimeter proton beams, similar to grid therapy or microbeam radiation radiotherapy (MRT) using X-rays, has recently been invented at the ion microprobe SNAKE in Munich. The aim of this new concept is to minimize normal tissue injuries in the entrance channel and especially in the skin by irradiating only a small percentage of the cells in the total irradiation field, while maintaining tumor control via a homogeneous dose in the tumor, just like in conventional broad beam radiotherapy. This can be achieved by optimizing minibeam sizes and distances according to the prevailing tumor size and depth such that after widening of the minibeams due to proton interactions in the tissue, the overlapping minibeams produce a homogeneous dose distribution throughout the tumor. The aim of this work was to elucidate the prospects of minibeam radiation therapy compared to conventional homogeneous broad beam radiotherapy in theory and in experimental studies at the ion microprobe SNAKE. Treatment plans for model tumors of different sizes and depths were created using the planning software LAPCERR, to elaborate suitable minibeam sizes and distances for the individual tumors. Radiotherapy-relevant inter-beam distances required to obtain a homogeneous dose in the target volume were found to be in the millimeter range. First experiments using proton minibeams of only 10 μm and 50 μm size (termed microchannels in the corresponding publication Zlobinskaya et al. 2013) and therapy-conform larger dimensions of 100 μm and 180 μm were performed in the artificial human in-vitro skin model EpiDermFT trademark (MatTek). The corresponding inter-beam distances were 500 μm, 1mm and 1.8 mm, respectively, leading to irradiation of only a few percent of the cells

    Liu, Wenjia; Li, Yiyang; Ding, Xianting


    Engineering surfaces with functional polymers is a crucial issue in the field of micro/nanofabrication and cell-material interface studies. For many applications of surface patterning, it does not need cells to attach on the whole surface. Herein, we introduce a novel polymer fabrication protocol of off-stoichiometry thiol-ene (OSTE) polymers to create heterogeneity on the surface by utilizing 3D printing and soft-lithography. By choosing two OSTE polymers with different functional groups, we create a pattern where only parts of the surface can facilitate cell adhesion. We also study the hydrophilic property of OSTE polymers by mixing poly(ethylene glycol) (PEG) directly with pre-polymers and plasma treatments afterwards. Moreover, we investigate the effect of functional groups' excess ratio and hydrophilic property on the cell adhesion ability of OSTE polymers. The results show that the cell adhesion ability of OSTE materials can be tuned within a wide range by the coupling effect of functional groups' excess ratio and hydrophilic property. Meanwhile, by mixing PEG with pre-polymers and undergoing oxygen plasma treatment afterward can significantly improve the hydrophilic property of OSTE polymers.

    The biological effectiveness of proton beams varies with depth, spot size and lateral distance from the beam central axis. The aim of this work is to incorporate proton relative biological effectiveness (RBE) and equivalent uniform dose (EUD) considerations into comparisons of broad beam and highly modulated proton minibeams. A Monte Carlo model of a small animal proton beamline is presented. Dose and variable RBE is calculated on a per-voxel basis for a range of energies (30–109 MeV). For an open beam, the RBE values at the beam entrance ranged from 1.02–1.04, at the Bragg peak (BP) from 1.3 to 1.6, and at the distal end of the BP from 1.4 to 2.0. For a 50 MeV proton beam, a minibeam collimator designed to produce uniform dose at the depth of the BP peak, had minimal impact on the open beam RBE values at depth. RBE changes were observed near the surface when the collimator was placed flush with the irradiated object, due to a higher neutron contribution derived from proton interactions with the collimator. For proton minibeams, the relative mean RBE weighted entrance dose (RWD) was ~25% lower than the physical mean dose. A strong dependency of the EUD with fraction size was observed. For 20 Gy fractions, the EUD varied widely depending on the radiosensitivity of the cells. For radiosensitive cells, the difference was up to ~50% in mean dose and ~40% in mean RWD and the EUD trended towards the valley dose rather than the mean dose. For comparative studies of uniform dose with spatially fractionated proton minibeams, EUD derived from a per-voxel RWD distribution is recommended for biological assessments of reproductive cell survival and related endpoints.

    Purpose: This Monte Carlo simulation work aims at studying a new radiotherapy approach called proton-minibeam radiation therapy (pMBRT). The main objective of this proof of concept was the evaluation of the possible gain in tissue sparing, thanks to the spatial fractionation of the dose, which could be used to deposit higher and potentially curative doses in clinical cases where tissue tolerances are a limit for conventional methods. Methods: Monte Carlo simulations (GATE v.6) have been used as a method to calculate the ratio of the peak-to-valley doses (PVDR) for arrays of proton minibeams of 0.7 mm width and several center-to-center distances, at different depths in a water phantom. The beam penumbras were also evaluated as an important parameter for tissue sparing, for example, in the treatment of non-cancer diseases like epilepsy. Two proton energies were considered in this study: a clinically relevant energy (105 MeV) and a very high energy (1 GeV), to benefit from a reduced lateral scattering. For the latter case, an interlaced geometry was also evaluated. Results: Higher or similar PVDR than the ones obtained in x-rays minibeam radiation therapy were achieved in several pMBRT configurations. In addition, for the two energies studied, the beam penumbras are smaller than in the case of Gamma Knife radiosurgery. Conclusions: The high PVDR obtained for some configurations and the small penumbras in comparison with existing radiosurgery techniques, suggest a potential gain in healthy tissue sparing in this new technique. Biological studies are warranted to assess the effects of pMBRT on both normal and tumoral tissues.

    Purpose: To evaluate the efficacy of 'interleaved carbon minibeams' for ablating a 6.5-mm target in a rabbit brain with little damage to the surrounding brain. The method is based on the well-established tissue-sparing effect of arrays of thin planes of radiation. Methods and Materials: Broad carbon beams from the National Aeronautics and Space Agency Space Radiation Facility at Brookhaven National Laboratory were segmented into arrays of parallel, horizontal, 0.3-mm-thick planar beams (minibeams). The minibeams' gradual broadening in tissues resulted in 0.525-mm beam thickness at the target's proximal side in the spread-out Bragg peak. Interleaving was therefore implemented by choosing a 1.05 mm beam spacing on-center. The anesthetized rabbit, positioned vertically on a stage capable of rotating about a vertical axis, was exposed to arrays from four 90 Degree-Sign angles, with the stage moving up by 0.525 mm in between. This produced a solid radiation field at the target while exposing the nontargeted tissues to single minibeam arrays. The target 'physical' absorbed dose was 40.2 Gy. Results: The rabbit behaved normally during the 6-month observation period. Contrast magnetic resonance imaging and hematoxylin and eosin histology at 6 months showed substantial focal target damage with little damage to the surrounding brain. Conclusion: We plan to evaluate the method's therapeutic efficacy by comparing it with broad-beam carbon therapy in animal models. The method's merits would combine those of carbon therapy (i.e., tight target dose because of the carbon's Bragg-peak, sharp dose falloff, and high relative biological effectiveness at the target), together with the method's low impact on the nontargeted tissues. The method's smaller impact on the nontargeted brain might allow carbon therapy at higher target doses and/or lower normal tissue impact, thus leading to a more effective treatment of radioresistant

    Purpose: Proton minibeam radiation therapy is a novel approach to minimize normal tissue damage in the entrance channel by spatial fractionation while keeping tumor control through a homogeneous tumor dose using beam widening with an increasing track length. In the present study, the dose distributions for homogeneous broad beam and minibeam irradiation sessions were simulated. Also, in an animal study, acute normal tissue side effects of proton minibeam irradiation were compared with homogeneous irradiation in a tumor-free mouse ear model to account for the complex effects on the immune system and vasculature in an in vivo normal tissue model. Methods and Materials: At the ion microprobe SNAKE, 20-MeV protons were administered to the central part (7.2 × 7.2 mm{sup 2}) of the ear of BALB/c mice, using either a homogeneous field with a dose of 60 Gy or 16 minibeams with a nominal 6000 Gy (4 × 4 minibeams, size 0.18 × 0.18 mm{sup 2}, with a distance of 1.8 mm). The same average dose was used over the irradiated area. Results: No ear swelling or other skin reactions were observed at any point after minibeam irradiation. In contrast, significant ear swelling (up to fourfold), erythema, and desquamation developed in homogeneously irradiated ears 3 to 4 weeks after irradiation. Hair loss and the disappearance of sebaceous glands were only detected in the homogeneously irradiated fields. Conclusions: These results show that proton minibeam radiation therapy results in reduced adverse effects compared with conventional homogeneous broad-beam irradiation and, therefore, might have the potential to decrease the incidence of side effects resulting from clinical proton and/or heavy ion therapy.

  9. Monochromatic minibeam radiotherapy: theoretical and experimental dosimetry for preclinical treatment plans (United States)

    Deman, P.; Vautrin, M.; Stupar, V.; Barbier, E. L.; Elleaume, H.; Esteve, F.; Adam, J. F.


    Monochromatic x-ray minibeam radiotherapy is a new radiosurgery approach based on arrays of submillimetric interlaced planar x-ray beams. The aim of this study was to characterize the dose distributions obtained with this new modality when being used for preclinical trials. Monte Carlo simulations were performed in water phantoms. Percentage depth-dose curves and dose profiles were computed for single incidences and interleaved incidences of 80 keV planar x-ray minibeam (0.6 × 5 mm) arrays. Peak to valley dose ratios were also computed at various depths for an increasing number of minibeams. 3D experimental polymer gel (nPAG) dosimetry measurements were performed using MRI devices designed for small animal imaging. These very high spatial resolution (50 µm) dose maps were compared to the simulations. Preclinical minibeams dose distributions were fully characterized. Experimental dosimetry correlated well with Monte Carlo calculations (Student t-tests: p > 0.1). F98 tumor-bearing rats were also irradiated with interleaved minibeams (80 keV, prescribed dose: 25 Gy). This associated preclinical trial serves as a proof of principle of the technique. The mean survival time of irradiated glioma-bearing rats increased significantly, when compared to the untreated animals (59.6 ± 2.8 days versus 28.25 ± 0.75 days, p < 0.001).

  10. Theoretical dosimetric evaluation of carbon and oxygen minibeam radiation therapy. (United States)

    González, Wilfredo; Peucelle, Cécile; Prezado, Yolanda


    Charged particles have several advantages over x-ray radiations, both in terms of physics and radiobiology. The combination of these advantages with those of minibeam radiation therapy (MBRT) could help enhancing the therapeutic index for some cancers with poor prognosis. Among the different ions explored for therapy, carbon ions are considered to provide the optimum physical and biological characteristics. Oxygen could be advantageous due to a reduced oxygen enhancement ratio along with a still moderate biological entrance dose. The aforementioned reasons justified an in-depth evaluation of the dosimetric features of carbon and oxygen minibeam radiation therapy to establish the interest of further explorations of this avenue. The GATE/Geant4 6.2 Monte Carlo simulation platform was employed to simulate arrays of rectangular carbon and oxygen minibeams (600 μm × 2 cm) at a water phantom entrance. They were assumed to be generated by means of a magnetic focusing. The irradiations were performed with a 2-cm-long spread-out Bragg peak (SOBP) centered at 7-cm-depth. Several center-to-center (c-t-c) distances were considered. Peak and valley doses, as well as peak-to-valley dose ratio (PVDR) and the relative contribution of nuclear fragments and electromagnetic processes were assessed. In addition, the type and proportion of the secondary nuclear fragments were evaluated in both peak and valley regions. Carbon and oxygen MBRT lead to very similar dose distributions. No significant advantage of oxygen over carbon ions was observed from physical point of view. Favorable dosimetric features were observed for both ions. Thanks to the reduced lateral scattering, the standard shape of the depth dose curves (in the peaks) is maintained even for submillimetric beam sizes. When a narrow c-t-c is considered (910-980 μm), a (quasi) homogenization of the dose can be obtained at the target, while a spatial fractionation of the dose is maintained in the proximal normal tissues with

    The macromolecular crystallography beamlines at third-generation synchrotron facilities play a central role in solving macromolecular crystal structures and also in understanding the biological function at molecular levels. The MX beamline BL17U at Shanghai Synchrotron Radiation Facility is a typical standard MX beamline with a focused beam size (H × V) of FWHM around 80 μm × 45 μm. However the protein samples brought to the beamline are down to 5-10 m from the important and challenging science project now. These samples require smaller size beam. In order to achieve the mini-size beamline, two mini-beam modes have been developed on BL17U: the pinhole-based mini-beam and the focused mini-beam by compound refractive lens (CRL). Compared to the pinhole-based mode, three times increase in flux is obtained by the CRL mode at a similar beam size. The flux gain obtained by the CRL needs to be considered for data collection strategies. It takes few minutes to switch the beamline from the normal to CRL mini-beam mode.

  12. Minibeam therapy with protons and light ions: physical feasibility and potential to reduce radiation side effects and to facilitate hypofractionation. (United States)

    Dilmanian, F Avraham; Eley, John G; Krishnan, Sunil


    Despite several advantages of proton therapy over megavoltage x-ray therapy, its lack of proximal tissue sparing is a concern. The method presented here adds proximal tissue sparing to protons and light ions by turning their uniform incident beams into arrays of parallel, small, or thin (0.3-mm) pencil or planar minibeams, which are known to spare tissues. As these minibeams penetrate the tissues, they gradually broaden and merge with each other to produce a solid beam. Broadening of 0.3-mm-diameter, 109-MeV proton pencil minibeams was measured using a stack of radiochromic films with plastic spacers. Monte Carlo simulations were used to evaluate the broadening in water of minibeams of protons and several light ions and the dose from neutron generated by collimator. A central parameter was tissue depth, where the beam full width at half maximum (FWHM) reached 0.7 mm, beyond which tissue sparing decreases. This depth was 22 mm for 109-MeV protons in a film stack. It was also found by simulations in water to be 23.5 mm for 109 MeV proton pencil minibeams and 26 mm for 116 MeV proton planar minibeams. For light ions, all with 10 cm range in water, that depth increased with particle size; specifically it was 51 mm for Li-7 ions. The ∼2.7% photon equivalent neutron skin dose from the collimator was reduced 7-fold by introducing a gap between the collimator and the skin. Proton minibeams can be implemented at existing particle therapy centers. Because they spare the shallow tissues, they could augment the efficacy of proton therapy and light particle therapy, particularly in treating tumors that benefit from sparing of proximal tissues such as pediatric brain tumors. They should also allow hypofractionated treatment of all tumors by allowing the use of higher incident doses with less concern about proximal tissue damage. Copyright © 2015 Elsevier Inc.

    Purpose: The purpose of this study was to evaluate high-dose single fraction delivered with monochromatic X-rays minibeams for the radiotherapy of primary brain tumors in rats. Methods and Materials: Two groups of healthy rats were irradiated with one anteroposterior minibeam incidence (four minibeams, 123 Gy prescribed dose at 1 cm depth in the brain) or two interleaved incidences (54 Gy prescribed dose in a 5 Multiplication-Sign 5 Multiplication-Sign 4.8 mm{sup 3} volume centered in the right hemisphere), respectively. Magnetic resonance imaging (MRI) follow-up was performed over 1 year. T2-weighted (T2w) images, apparent diffusion coefficient (ADC), and blood vessel permeability maps were acquired. F98 tumor bearing rats were also irradiated with interleaved minibeams to achieve a homogeneous dose of 54 Gy delivered to an 8 Multiplication-Sign 8 Multiplication-Sign 7.8 mm{sup 3} volume centered on the tumor. Anatomic and functional MRI follow-up was performed every 10 days after irradiation. T2w images, ADC, and perfusion maps were acquired. Results: All healthy rats were euthanized 1 year after irradiation without any clinical alteration visible by simple examination. T2w and ADC measurements remain stable for the single incidence irradiation group. Localized Gd-DOTA permeability, however, was observed 9 months after irradiation for the interleaved incidences group. The survival time of irradiated glioma bearing rats was significantly longer than that of untreated animals (49 {+-} 12.5 days versus 23.3 {+-} 2 days, p < 0.001). The tumoral cerebral blood flow and blood volume tend to decrease after irradiation. Conclusions: This study demonstrates the sparing effect of minibeams on healthy tissue. The increased life span achieved for irradiated glioma bearing rats was similar to the one obtained with other radiotherapy techniques. This experimental tumor therapy study shows the feasibility of using X-ray minibeams with high doses in brain tumor radiotherapy.

    Purpose: The dose tolerances of normal tissues continue being the main limitation in radiotherapy. To overcome it, we recently proposed a novel concept: proton minibeam radiation therapy (pMBRT) [1]. It allies the physical advantages of protons with the normal tissue preservation observed when irradiated with submillimetric spatially fractionated beams (minibeam radiation therapy) [2]. The dose distributions are such that the tumor receives a homogeneous dose distribution, while normal tissues benefit from the spatial fractionation of the dose. The objective of our work was to implement this promising technique at a clinical center (Proton therapy center in Orsay) in order to evaluate the potential gain in tissue sparing. Methods: Dose distributions were measured by means of gafchromic films and a PTW microdiamond detector (60019). Once the dosimetry was established, the whole brain of 7 weeks old male Fischer 344 rats was irradiated. Half of the animals received conventional seamless proton irradiation (25 Gy in one fraction). The other rats were irradiated with pMBRT (58 Gy peak dose in one fraction). The average dose deposited in the same targeted volume was in both cases 25 Gy. Results: The first complete set of dosimetric data in such small proton field sizes was obtained [3]. Rats treated with conventional proton irradiation exhibited severe moist desquamation and permanent epilation afterwards. The minibeam group, on the other hand, exhibited no skin damage and no clinical symptoms. MRI imaging and histological analysis are planned at 6 months after irradiation. Conclusion: Our preliminary results indicate that pMBRT leads to an increase in tissue resistance. This can open the door to an efficient treatment of very radioresistant tumours. [1] Prezado et al.

  16. The effect of pattern dimensions on the thermal decay of polymer patterns created by nanoimprint lithography (United States)

    Kearns, Kenneth; Ro, H. W.; Patrick, Heather J.; Germer, Thomas A.; Soles, Christopher


    Spectroscopic ellipsometry, combined with rigorous coupled wave modeling, is used to characterize the thermal decay of polymeric patterns prepared by nanoimprint lithography. When the residual layer is on the order of 10 nm, the pattern decay kinetics of patterns with a 420 nm periodicity near their glass transition temperatures are nearly an order of magnitude slower than patterns sitting on a thick residual layer. Pattern decay is not observed when the periodicity increased to 800 nm for the 10 nm residual layers. Polystyrene, poly(methyl methacrylate), and poly(4-t-butyl styrene) all show this behavior suggesting that changes in entanglement density are not important. The difference in the radius of curvature for the two different pattern periodicities is the likely origin for the pattern decay. The sensitivity of the technique to thin residual layers and nanoscale patterns is enhanced with an optical cavity of Si O2 between the polymer and Si substrate. The Si O2 layer enhances the changes in the ellipsometric parameters alpha and beta, which are related to psi and delta. The model dependent scatterometry data is corroborated by atomic force microscopy.

  17. A hydrodynamic instability is used to create aesthetically appealing patterns in painting. (United States)

    Zetina, Sandra; Godínez, Francisco A; Zenit, Roberto


    Painters often acquire a deep empirical knowledge of the way in which paints and inks behave. Through experimentation and practice, they can control the way in which fluids move and deform to create textures and images. David Alfaro Siqueiros, a recognized Mexican muralist, invented an accidental painting technique to create new and unexpected textures. By pouring layers of paint of different colors on a horizontal surface, the paints infiltrate into each other creating patterns of aesthetic value. In this investigation, we reproduce the technique in a controlled manner. We found that for the correct color combination, the dual viscous layer becomes Rayleigh-Taylor unstable: the density mismatch of the two color paints drives the formation of a spotted pattern. Experiments and a linear instability analysis were conducted to understand the properties of the process. We also argue that this flow configuration can be used to study the linear properties of this instability.

  19. Minibeam radiotherapy with small animal irradiators; in vitro and in vivo feasibility studies (United States)

    Bazyar, Soha; Inscoe, Christina R.; O’Brian, E. Timothy; Zhou, Otto; Lee, Yueh Z.


    Minibeam radiation therapy (MBRT) delivers an ultrahigh dose of x-ray (⩾100 Gy) in 200–1000 µm beams (peaks), separated by wider non-irradiated regions (valleys) usually as a single temporal fraction. Preclinical studies performed at synchrotron facilities revealed that MBRT is able to ablate tumors while maintaining normal tissue integrity. The main purpose of the present study was to develop an efficient and accessible method to perform MBRT using a conventional x-ray irradiator. We then tested this new method both in vitro and in vivo. Using commercially available lead ribbon and polyethylene sheets, we constructed a collimator that converted the cone beam of an industrial irradiator to 44 identical beams (collimator size  ≈  4  ×  10 cm). The dosimetry characteristics of the generated beams were evaluated using two different radiochromic films (beam FWHM  =  246  ±  32 µm center-to-center  =  926  ±  23 µm peak-to-valley dose ratio  =  24.35  ±  2.10 collimator relative output factor  =  0.84  ±  0.04). Clonogenic assays demonstrated the ability of our method to induce radiobiological cell death in two radioresistant murine tumor cell lines (TRP  =  glioblastoma B16-F10  =  melanoma). A radiobiological equivalent dose (RBE) was calculated by evaluating the acute skin response to graded doses of MBRT and conventional radiotherapy (CRT). Normal mouse skin demonstrated resistance to doses up to 150 Gy on peak. MBRT significantly extended the survival of mice with flank melanoma tumors compared to CRT when RBE were applied (overall p  <  0.001). Loss of spatial resolution deep in the tissue has been a major concern. The beams generated using our collimator maintained their resolution in vivo (mouse brain tissue) and up to 10 cm deep in the radiochromic film. In conclusion, the initial dosimetric, in vitro and in vivo evaluations confirmed the

    Still in testing phase, radiation therapy with mini-beams is presented as a promising form of treatment. The irradiation with beams constituted by a group of parallel strips of radiation and shade (peaks and valleys), each an of the which has a width of the order of microns. We studied using Monte Carlo simulation, the effect of the brain caused by the heartbeat pulsed on the reason of dose peak-valley in cranial radiotherapy with mini-beams, depending on the width of peak and the rate of irradiation.

    Full Text Available Abstract Background In the quest of a curative radiotherapy treatment for gliomas new delivery modes are being explored. At the Biomedical Beamline of the European Synchrotron Radiation Facility (ESRF, a new spatially-fractionated technique, called Minibeam Radiation Therapy (MBRT is under development. The aim of this work is to compare the effectiveness of MBRT and broad-beam (BB synchrotron radiation to treat F98 glioma rat cells. A dose escalation study was performed in order to delimit the range of doses where a therapeutic effect could be expected. These results will help in the design and optimization of the forthcoming in vivo studies at the ESRF. Methods Two hundred thousand F98 cells were seeded per well in 24-well plates, and incubated for 48 hours before being irradiated with spatially fractionated and seamless synchrotron x-rays at several doses. The percentage of each cell population (alive, early apoptotic and dead cells, where either late apoptotic as necrotic cells are included was assessed by flow cytometry 48 hours after irradiation, whereas the metabolic activity of surviving cells was analyzed on days 3, 4, and 9 post-irradiation by using QBlue test. Results The endpoint (or threshold dose from which an important enhancement in the effectiveness of both radiation treatments is achieved obtained by flow cytometry could be established just before 12 Gy in the two irradiation schemes, whilst the endpoints assessed by the QBlue reagent, taking into account the cell recovery, were set around 18 Gy in both cases. In addition, flow cytometric analysis pointed at a larger effectiveness for minibeams, due to the higher proportion of early apoptotic cells. Conclusions When the valley doses in MBRT equal the dose deposited in the BB scheme, similar cell survival ratio and cell recovery were observed. However, a significant increase in the number of early apoptotic cells were found 48 hours after the minibeam radiation in comparison with

    Creating patterns of biomolecules and cells has been applied widely in many fields associated with the life sciences, including diagnostics. In these applications it has become increasingly apparent that the spatiotemporal arrangement of biological molecules in vitro is important for the investigation of the cellular functions found in vivo. However, the cell patterning techniques often used are limited to creating 2D functional surfaces on glass and silicon. In addition, in general, these procedures are not easy to implement in conventional biological laboratories. Here, we show the formation of a living poly(ethylene glycol) (PEG) layer that can be patterned with visible light on plastic surfaces. This new and simple method can be expanded to pattern multiple types of biomolecule on either a previously formed PEG layer or a plastic substrate. Using common plastic wares (i.e., polyethylene films and polystyrene cell culture Petri-dishes), we demonstrate that these PEG-modified surfaces have a high resistance to protein adsorption and cell adhesion, while at the same time, being capable of undergoing further molecular grafting with bioactive motifs. With a photomask and a fluid delivery system, we illustrate a flexible way to immobilize biological functions with a high degree of 2D and 3D spatial control. We anticipate that our method can be easily implemented in a typical life science laboratory (without the need for specialized lithography equipment) offering the prospect of imparting desirable properties to plastic products, for example, the creation of functional microenvironments in biological studies or reducing biological adhesion to surfaces.

  3. SU-C-204-02: Behavioral and Pathologic Differences in Mice Exposed to Proton Minibeam Arrays Versus Proton Broad Beams

    Purpose: Minibeam therapy using protons or light-ions offers a theoretical reduction of biologic damage to tissues upstream of a tumor compared to broad-beam therapy while providing equal tumor control. The purpose of this study was to investigate behavioral and pathologic differences in mice after exposure of healthy brain to proton minibeam arrays versus proton broad beams. Methods: Twenty-four C57BL/6J juvenile mice were divided into 5 study arms: sham irradiation (NoRT), broad-beam 10 Gy (BB10), minibeam 10Gy (MB10), broad-beam 30 Gy (BB30), and minibeam 30 Gy (MB30), approximate integral entrance doses. Circular beams of 100 MeV protons with 7-mm diameter were delivered laterally through the brain, either as broad beams or as planar minibeam arrays having 300-micron beam width and 1-mm spacing on center. Mice were followed for 8 months using standard behavioral tests. Pathologic studies were carried out at 8 months after irradiation. Results: Peak entrance doses were 10.0, 23.8, 30.0, and 71.3 Gy for mice in BB10, MB10, BB30, and MB30, respectively. Despite the high single-fraction doses, no animals showed signs of radiation sickness or neurophysical impairment over the 8-month study duration. The Morris water maze alternate-starting-position trial showed significant evidence of better spatial learning for mice in MB10 versus BB10 (p=0.026), but other behavioral tests showed no significant differences. Glial fibrillary acidic protein stains showed gliosis in arms BB10, BB30, and MB30 but not in NoRT or MB10. A secondary finding was categorically higher epilation in broad-beam arms compared with their minibeam dose counterparts. Conclusion: Our findings indicate trends that, despite the higher peak doses, proton minibeam therapy can reduce radiation side effects in shallow tissue and brain compared to proton broadbeam therapy. As the behavioral findings were mixed, confirmation studies are needed with larger numbers of animals. AAPM Research Seed Funding Grant.

  4. Minibeam radiation therapy for the management of osteosarcomas: A Monte Carlo study

    Martínez-Rovira, I.; Prezado, Y., E-mail: [Laboratoire d’Imagerie et Modélisation en Neurobiologie et Cancérologie (IMNC), Centre National de la Recherche Scientifique (CNRS), Campus universitaire, Bât. 440, 1er étage, 15 rue Georges Clemenceau, 91406 Orsay cedex (France)


    Purpose: Minibeam radiation therapy (MBRT) exploits the well-established tissue-sparing effect provided by the combination of submillimetric field sizes and a spatial fractionation of the dose. The aim of this work is to evaluate the feasibility and potential therapeutic gain of MBRT, in comparison with conventional radiotherapy, for osteosarcoma treatments. Methods: Monte Carlo simulations (PENELOPE/PENEASY code) were used as a method to study the dose distributions resulting from MBRT irradiations of a rat femur and a realistic human femur phantoms. As a figure of merit, peak and valley doses and peak-to-valley dose ratios (PVDR) were assessed. Conversion of absorbed dose to normalized total dose (NTD) was performed in the human case. Several field sizes and irradiation geometries were evaluated. Results: It is feasible to deliver a uniform dose distribution in the target while the healthy tissue benefits from a spatial fractionation of the dose. Very high PVDR values (⩾20) were achieved in the entrance beam path in the rat case. PVDR values ranged from 2 to 9 in the human phantom. NTD{sub 2.0} of 87 Gy might be reached in the tumor in the human femur while the healthy tissues might receive valley NTD{sub 2.0} lower than 20 Gy. The doses in the tumor and healthy tissues might be significantly higher and lower than the ones commonly delivered used in conventional radiotherapy. Conclusions: The obtained dose distributions indicate that a gain in normal tissue sparing might be expected. This would allow the use of higher (and potentially curative) doses in the tumor. Biological experiments are warranted.

  5. Dimensional accuracy of dental casting patterns created by 3D printers. (United States)

    Ishida, Yoshiki; Miyasaka, Taira


    Contrary to widespread incise CAD/CAM, little is known about the dental application of 3D printing, especially the possibility of using 3D printing with organic material. The resin patterns of a full crown model were created by four types of 3D printers, a thermofusion device (CX), a digital light processing stereo-lithograph device (B9), a laser stereo-lithograph device (DW) and a multi-jet modeling device (PJ). The dimensional accuracy of the outer and inner diameters and depths of the created model crowns, and the surface roughness of sidewall were investigated. The outer diameters were smaller than the designed value in most conditions. The inner diameters were smaller than the designed value in any enlargement ratio except B9. The depth of CX or B9 tended to become shallower, though that of PJ or DW tended to increase. The surface roughness along the tooth axis direction was greater than that perpendicular to the tooth axis.

  6. Simple growth patterns can create complex trajectories for the ontogeny of constitutive chemical defences in seaweeds.

    Directory of Open Access Journals (Sweden)

    Nicholas A Paul

    Full Text Available All of the theory and most of the data on the ecology and evolution of chemical defences derive from terrestrial plants, which have considerable capacity for internal movement of resources. In contrast, most macroalgae--seaweeds--have no or very limited capacity for resource translocation, meaning that trade-offs between growth and defence, for example, should be localised rather than systemic. This may change the predictions of chemical defence theories for seaweeds. We developed a model that mimicked the simple growth pattern of the red seaweed Asparagopsis armata which is composed of repeating clusters of somatic cells and cells which contain deterrent secondary chemicals (gland cells. To do this we created a distinct growth curve for the somatic cells and another for the gland cells using empirical data. The somatic growth function was linked to the growth function for defence via differential equations modelling, which effectively generated a trade-off between growth and defence as these neighbouring cells develop. By treating growth and defence as separate functions we were also able to model a trade-off in growth of 2-3% under most circumstances. However, we found contrasting evidence for this trade-off in the empirical relationships between growth and defence, depending on the light level under which the alga was cultured. After developing a model that incorporated both branching and cell division rates, we formally demonstrated that positive correlations between growth and defence are predicted in many circumstances and also that allocation costs, if they exist, will be constrained by the intrinsic growth patterns of the seaweed. Growth patterns could therefore explain contrasting evidence for cost of constitutive chemical defence in many studies, highlighting the need to consider the fundamental biology and ontogeny of organisms when assessing the allocation theories for defence.

  9. Characterization of microtopography and its influence on vegetation patterns in created wetlands (United States)

    Moser, K.; Ahn, C.; Noe, G.


    Created wetlands are increasingly used to mitigate wetland loss. Thus, identifying wetland creation methods that enhance ecosystem development might increase the likelihood of mitigation success. Noting that the microtopographic variation found in natural wetland settings may not commonly be found in created wetlands, this study explores relationships between induced microtopography, hydrology, and plant species richness/ diversity in non-tidal freshwater wetlands, comparing results from two created wetland complexes with those from a mature reference wetland complex in northern Virginia. Elevation, steel rod oxidation depth, and species cover were measured along replicate multiscale (0.5 m-, 1 m-, 2 m-, and 4 m-diameter) tangentially conjoined circular transects in each wetland. Microtopography was surveyed using a total station and results used to derive three roughness indices: tortuosity, limiting slope, and limiting elevation difference. Steel rod oxidation depth was used to estimate water table depth, with data collected four times during the growing season for each study site. Plant species cover was estimated visually in 0.2 m2 plots surveyed at peak growth and used to assess species richness, diversity, and wetland prevalence index. Differences in each attribute were examined among disked and non-disked created wetlands and compared to a natural wetland as a reference. Disked and non-disked created wetlands differed in microtopography, both in terms of limiting elevation difference and tortuosity. However, both were within the range of microtopography encompassed by natural wetlands. Disked wetlands supported higher plant diversity and species richness than either natural or non-disked wetlands, as well as greater within-site species assemblage variability than non-disked wetlands. Irrespective of creation method, plant diversity in created wetlands was correlated with tortuosity and limiting elevation difference, similar to correlations observed for

  10. RNA silencing in white petunia flowers creates pigmentation patterns invisible to the human eye. (United States)

    Matsubara, Kiyoshi; Kei, Satoko; Koizumi, Mayuko; Kodama, Hiroaki; Ando, Toshio


    Modern commercial petunias exhibit a wide range of flower colors, which can be observed in gardens. In this study, we present a petunia cultivar that exhibits a floral pattern that is invisible to humans but is possibly visible to pollinating insects. We show that this hidden pattern is established by differentially localized accumulation of flavonols and cinnamic acid derivatives in the corolla limb. This accumulation is caused by a combination of two distinct mechanisms that inhibit anthocyanin biosynthesis: a loss-of-function mutation in the ANTHOCYANIN2, and localized RNA-silencing of CHALCONE SYNTHASE-A.

    A hydrothermal method based on the use of hydrogen peroxide is described to grow a homogeneous layer of tungsten oxide (WO3) on a platinum (Pt) film supported on a silicon wafer. WO3 growth is highly selective for Pt when present on silicon in a patterned arrangement, demonstrating that Pt catalyzes decomposition of the WO3 precursor in solution. The obtained Pt/WO3 interface yields high photocurrents of 1.1 mA/cm(2) in photoelectrochemical water splitting when illuminated by a solar simulator. The photocurrents are significantly higher than most previously reported values for hydrothermally grown layers on indium-tin oxide and fluorine-tin oxide glasses. The selective growth method thus provides new options to effectively implement WO3 in photoelectrochemical devices.

  14. A User-Centered Framework for Deriving A Conceptual Design From User Experiences: Leveraging Personas and Patterns to Create Usable Designs (United States)

    Javahery, Homa; Deichman, Alexander; Seffah, Ahmed; Taleb, Mohamed

    Patterns are a design tool to capture best practices, tackling problems that occur in different contexts. A user interface (UI) design pattern spans several levels of design abstraction ranging from high-level navigation to low-level idioms detailing a screen layout. One challenge is to combine a set of patterns to create a conceptual design that reflects user experiences. In this chapter, we detail a user-centered design (UCD) framework that exploits the novel idea of using personas and patterns together. Personas are used initially to collect and model user experiences. UI patterns are selected based on personas pecifications; these patterns are then used as building blocks for constructing conceptual designs. Through the use of a case study, we illustrate how personas and patterns can act as complementary techniques in narrowing the gap between two major steps in UCD: capturing users and their experiences, and building an early design based on that information. As a result of lessons learned from the study and by refining our framework, we define a more systematic process called UX-P (User Experiences to Pattern), with a supporting tool. The process introduces intermediate analytical steps and supports designers in creating usable designs.

  17. Not All Pacifiers Are Created Equal: A Mechanical Examination of Pacifiers and Their Influence on Suck Patterning. (United States)

    Zimmerman, Emily; Forlano, Jaclene; Gouldstone, Andrew


    Many pacifier companies advertise that their product is the "best choice" to support proper sucking, feeding, and dental development; however, very little evidence exists to support these claims. As the primary differences across pacifiers are structural and mechanical, the goals of this study were to measure such properties of commercially available pacifiers and to examine how these properties alter suck patterning in healthy, full-term infants. Seven commonly utilized pacifiers were mechanically tested for pull and compression stiffness levels and categorized into nipple shape types based on their aspect ratio. Next, 3 pacifiers (Soothie, GumDrop, and Freeflow) with the most salient differences in pull stiffness levels with 2 different pacifier nipple types were tested clinically on 16 full-term infants (≤ 6 months old) while measuring non-nutritive suck (NNS). A repeated measures analysis of variance revealed significant differences between NNS burst duration (p = .002), NNS cycles per burst (p = .002), and NNS cycles per minute (p = .006) and pacifier type. With each significant dependent measure, pairwise comparisons showed that the GumDrop and Freeflow pacifiers differed significantly on these measures. Pacifier compression, pull stiffness, and nipple shape type yield different NNS dynamics. These findings motivate further investigation into pacifier properties and suck patterning in young infants.

  18. Not all droughts are created equal: the impacts of interannual drought pattern and magnitude on grassland carbon cycling. (United States)

    Hoover, David L; Rogers, Brendan M


    Climate extremes, such as drought, may have immediate and potentially prolonged effects on carbon cycling. Grasslands store approximately one-third of all terrestrial carbon and may become carbon sources during droughts. However, the magnitude and duration of drought-induced disruptions to the carbon cycle, as well as the mechanisms responsible, remain poorly understood. Over the next century, global climate models predict an increase in two types of drought: chronic but subtle 'press-droughts', and shorter term but extreme 'pulse-droughts'. Much of our current understanding of the ecological impacts of drought comes from experimental rainfall manipulations. These studies have been highly valuable, but are often short term and rarely quantify carbon feedbacks. To address this knowledge gap, we used the Community Land Model 4.0 to examine the individual and interactive effects of pulse- and press-droughts on carbon cycling in a mesic grassland of the US Great Plains. A series of modeling experiments were imposed by varying drought magnitude (precipitation amount) and interannual pattern (press- vs. pulse-droughts) to examine the effects on carbon storage and cycling at annual to century timescales. We present three main findings. First, a single-year pulse-drought had immediate and prolonged effects on carbon storage due to differential sensitivities of ecosystem respiration and gross primary production. Second, short-term pulse-droughts caused greater carbon loss than chronic press-droughts when total precipitation reductions over a 20-year period were equivalent. Third, combining pulse- and press-droughts had intermediate effects on carbon loss compared to the independent drought types, except at high drought levels. Overall, these results suggest that interannual drought pattern may be as important for carbon dynamics as drought magnitude and that extreme droughts may have long-lasting carbon feedbacks in grassland ecosystems.

  2. Sitting Phase Monolayers of Polymerizable Phospholipids Create Dimensional, Molecular-Scale Wetting Control for Scalable Solution-Based Patterning of Layered Materials. (United States)

    Choong, Shi Wah; Russell, Shane R; Bang, Jae Jin; Patterson, Justin K; Claridge, Shelley A


    The use of dimensionally ordered ligands on layered materials to direct local electronic structure and interactions with the environment promises to streamline integration into nanostructured electronic, optoelectronic, sensing, and nanofluidic interfaces. Substantial progress has been made in using ligands to control substrate electronic structure. Conversely, using the exposed face of the ligand layer to structure wetting and binding interactions, particularly with scalable solution- or spray-processed materials, remains a significant challenge. However, nature routinely utilizes wetting control at scales from nanometer to micrometer to build interfaces of striking geometric precision and functional complexity, suggesting the possibility of leveraging similar control in synthetic materials. Here, we assemble striped "sitting" phases of polymerizable phospholipids on highly oriented pyrolytic graphite, producing a surface consisting of 1 nm wide hydrophilic stripes alternating with 5 nm wide hydrophobic stripes. Protruding, strongly wetting headgroup chemistries in these monolayers enable formation of rodlike wetted patterns with widths as little as ∼6 nm and lengths up to 100 nm from high-surface-tension liquids (aqueous solutions of glycerol) commonly utilized to assess interfacial wetting properties at larger length scales. In contrast, commonly used lying-down phases of diynoic acids with in-plane headgroups do not promote droplet sticking or directional spreading. These results point to a broadly applicable strategy for achieving high-resolution solution-based patterning on layered materials, utilizing nanometer-wide patterns of protruding, charged functional groups in a noncovalent monolayer to define pattern edges.

  8. Creating a learning culture. (United States)

    Mathewson, Karyn


    This column describes the efforts of an agency to build a learning culture as part of changing their approach to service delivery, when adopting a focus on psychiatric rehabilitation and recovery. This example of one organization's challenges and successes in workforce development provides an alternative approach to the common single-session staff training that typically fails to change practice. This description draws from published material on communities of practice, technical consultation, and agency experience. Training alone is not enough to create change. An organizational commitment to ongoing quality improvement, along with available and accessible technical assistance for staff, creates an environment where change is anticipated, managed, and celebrated.

  2. Foam patterns (United States)

    Chaudhry, Anil R; Dzugan, Robert; Harrington, Richard M; Neece, Faurice D; Singh, Nipendra P; Westendorf, Travis


    A method of creating a foam pattern comprises mixing a polyol component and an isocyanate component to form a liquid mixture. The method further comprises placing a temporary core having a shape corresponding to a desired internal feature in a cavity of a mold and inserting the mixture into the cavity of the mold so that the mixture surrounds a portion of the temporary core. The method optionally further comprises using supporting pins made of foam to support the core in the mold cavity, with such pins becoming integral part of the pattern material simplifying subsequent processing. The method further comprises waiting for a predetermined time sufficient for a reaction from the mixture to form a foam pattern structure corresponding to the cavity of the mold, wherein the foam pattern structure encloses a portion of the temporary core and removing the temporary core from the pattern independent of chemical leaching.

  3. Creating bulk nanocrystalline metal.

    Energy Technology Data Exchange (ETDEWEB)

    Fredenburg, D. Anthony (Georgia Institute of Technology, Atlanta, GA); Saldana, Christopher J. (Purdue University, West Lafayette, IN); Gill, David D.; Hall, Aaron Christopher; Roemer, Timothy John (Ktech Corporation, Albuquerque, NM); Vogler, Tracy John; Yang, Pin


    Nanocrystalline and nanostructured materials offer unique microstructure-dependent properties that are superior to coarse-grained materials. These materials have been shown to have very high hardness, strength, and wear resistance. However, most current methods of producing nanostructured materials in weapons-relevant materials create powdered metal that must be consolidated into bulk form to be useful. Conventional consolidation methods are not appropriate due to the need to maintain the nanocrystalline structure. This research investigated new ways of creating nanocrystalline material, new methods of consolidating nanocrystalline material, and an analysis of these different methods of creation and consolidation to evaluate their applicability to mesoscale weapons applications where part features are often under 100 {micro}m wide and the material's microstructure must be very small to give homogeneous properties across the feature.

  8. Creating Geoscience Leaders (United States)

    Buskop, J.; Buskop, W.


    The United Nations Educational, Scientific, and Cultural Organization recognizes 21 World Heritage in the United States, ten of which have astounding geological features: Wrangell St. Elias National Park, Olympic National Park, Mesa Verde National Park, Chaco Canyon, Glacier National Park, Carlsbad National Park, Mammoth Cave, Great Smokey Mountains National Park, Hawaii Volcanoes National Park, and Everglades National Park. Created by a student frustrated with fellow students addicted to smart phones with an extreme lack of interest in the geosciences, one student visited each World Heritage site in the United States and created one e-book chapter per park. Each chapter was created with original photographs, and a geological discovery hunt to encourage teen involvement in preserving remarkable geological sites. Each chapter describes at least one way young adults can get involved with the geosciences, such a cave geology, glaciology, hydrology, and volcanology. The e-book describes one park per chapter, each chapter providing a geological discovery hunt, information on how to get involved with conservation of the parks, geological maps of the parks, parallels between archaeological and geological sites, and how to talk to a ranger. The young author is approaching UNESCO to publish the work as a free e-book to encourage involvement in UNESCO sites and to prove that the geosciences are fun.

  10. Creating sustainable performance. (United States)

    Spreitzer, Gretchen; Porath, Christine


    What makes for sustainable individual and organizational performance? Employees who are thriving-not just satisfied and productive but also engaged in creating the future. The authors found that people who fit this description demonstrated 16% better overall performance, 125% less burnout, 32% more commitment to the organization, and 46% more job satisfaction than their peers. Thriving has two components: vitality, or the sense of being alive and excited, and learning, or the growth that comes from gaining knowledge and skills. Some people naturally build vitality and learning into their jobs, but most employees are influenced by their environment. Four mechanisms, none of which requires heroic effort or major resources, create the conditions for thriving: providing decision-making discretion, sharing information about the organization and its strategy, minimizing incivility, and offering performance feedback. Organizations such as Alaska Airlines, Zingerman's, Quicken Loans, and Caiman Consulting have found that helping people grow and remain energized at work is valiant on its own merits-but it can also boost performance in a sustainable way.

  12. Creating nanostars with buckyballs

    Energy Technology Data Exchange (ETDEWEB)

    Bae, Young K., E-mail:


    We report creating superradiant quantum nanoplasmas (nanostars) by impacting buckyballs at hypervelocities (v>100 km/s) in an innovative tabletop apparatus. The nanostars are estimated to have ∼10 TPa transient pressures and convert ∼35% of impact energy into soft-X-ray energy. The ultrahigh-efficiency conversion is proposed to result from Dicke Superradiance of Metastable Innershell Molecular State, originally discovered by the author and his colleagues in 1994. The usage of buckyballs and successful orders-of-magnitude scaling down of the apparatus size and complexity establish an innovative tabletop method for generating, studying, and utilizing matter in planetary or stellar interiors and open doors to numerous unprecedented applications.

  13. Creating Griffith Observatory (United States)

    Cook, Anthony


    Griffith Observatory has been the iconic symbol of the sky for southern California since it began its public mission on May 15, 1935. While the Observatory is widely known as being the gift of Col. Griffith J. Griffith (1850-1919), the story of how Griffith’s gift became reality involves many of the people better known for other contributions that made Los Angeles area an important center of astrophysics in the 20th century. Griffith began drawing up his plans for an observatory and science museum for the people of Los Angeles after looking at Saturn through the newly completed 60-inch reflector on Mt. Wilson. He realized the social impact that viewing the heavens could have if made freely available, and discussing the idea of a public observatory with Mt. Wilson Observatory’s founder, George Ellery Hale, and Director, Walter Adams. This resulted, in 1916, in a will specifying many of the features of Griffith Observatory, and establishing a committee managed trust fund to build it. Astronomy popularizer Mars Baumgardt convinced the committee at the Zeiss Planetarium projector would be appropriate for Griffith’s project after the planetarium was introduced in Germany in 1923. In 1930, the trust committee judged funds to be sufficient to start work on creating Griffith Observatory, and letters from the Committee requesting help in realizing the project were sent to Hale, Adams, Robert Millikan, and other area experts then engaged in creating the 200-inch telescope eventually destined for Palomar Mountain. A Scientific Advisory Committee, headed by Millikan, recommended that Caltech Physicist Edward Kurth be put in charge of building and exhibit design. Kurth, in turn, sought help from artist Russell Porter. The architecture firm of John C. Austin and Fredrick Ashley was selected to design the project, and they adopted the designs of Porter and Kurth. Philip Fox of the Adler Planetarium was enlisted to manage the completion of the Observatory and become its

  14. Creating the living brand. (United States)

    Bendapudi, Neeli; Bendapudi, Venkat


    It's easy to conclude from the literature and the lore that top-notch customer service is the province of a few luxury companies and that any retailer outside that rarefied atmosphere is condemned to offer mediocre service at best. But even companies that position themselves for the mass market can provide outstanding customer-employee interactions and profit from them, if they train employees to reflect the brand's core values. The authors studied the convenience store industry in depth and focused on two that have developed a devoted following: QuikTrip (QT) and Wawa. Turnover rates at QT and Wawa are 14% and 22% respectively, much lower than the typical rate in retail. The authors found six principles that both firms embrace to create a strong culture of customer service. Know what you're looking for: A focus on candidates' intrinsic traits allows the companies to hire people who will naturally bring the right qualities to the job. Make the most of talent: In mass-market retail, talent is generally viewed as a commodity, but that outlook becomes a self-fulfilling prophesy. Create pride in the brand: Service quality depends directly on employees' attachment to the brand. Build community: Wawa and QT have made concerted efforts to build customer loyalty through a sense of community. Share the business context: Employees need a clear understanding of how their company operates and how it defines success. Satisfy the soul: To win an employee's passionate engagement, a company must meet his or her needs for security, esteem, and justice.

  15. Creating alternatives in science (United States)


    Traditional scientist training at the PhD level does not prepare students to be competitive in biotechnology or other non-academic science careers. Some universities have developed biotechnology-relevant doctoral programmes, but most have not. Forming a life science career club makes a statement to university administrators that it is time to rework the curriculum to include biotechnology-relevant training. A career club can supplement traditional PhD training by introducing students to available career choices, help them develop a personal network and teach the business skills that they will need to be competitive in science outside of academia. This paper is an instructional guide designed to help students create a science career club at their own university. These suggestions are based on the experience gained in establishing such a club for the Graduate School at the University of Colorado Denver. We describe the activities that can be offered, the job descriptions for the offices required and potential challenges. With determination, a creative spirit, and the guidance of this paper, students should be able to greatly increase awareness of science career options, and begin building the skills necessary to become competitive in non-academic science.

    Monaghan, Duncan


    Duncan Monaghan is 33 years old and in his second year of an Arts degree in Creative Writing. He is a published poet and is currently producing a music CD. Duncan has a history of bipolar disorder which was diagnosed when he was nineteen: "It worried me at first a lot. It played on my mind constantly. I felt different from everybody else--I did not understand what was happening to me." Drawing on his life experiences, Duncan has been enhancing his recovery through creativity--in poetry, lyrics, music and story. "Life for me was a constant battle of relying on medication and appointments with my case manager...until I realized I could combine my recovery with my passions as a tool to use as an outlet to many of the "mind traps" I so often found hindering my own recovery." Duncan is Aboriginal and has experience of the mental health systems in most states and territories and now lives in Brisbane. This is a shortened version of his presentation at Creating Futures 2010.

  3. Creating visual explanations improves learning. (United States)

    Bobek, Eliza; Tversky, Barbara


    Many topics in science are notoriously difficult for students to learn. Mechanisms and processes outside student experience present particular challenges. While instruction typically involves visualizations, students usually explain in words. Because visual explanations can show parts and processes of complex systems directly, creating them should have benefits beyond creating verbal explanations. We compared learning from creating visual or verbal explanations for two STEM domains, a mechanical system (bicycle pump) and a chemical system (bonding). Both kinds of explanations were analyzed for content and learning assess by a post-test. For the mechanical system, creating a visual explanation increased understanding particularly for participants of low spatial ability. For the chemical system, creating both visual and verbal explanations improved learning without new teaching. Creating a visual explanation was superior and benefitted participants of both high and low spatial ability. Visual explanations often included crucial yet invisible features. The greater effectiveness of visual explanations appears attributable to the checks they provide for completeness and coherence as well as to their roles as platforms for inference. The benefits should generalize to other domains like the social sciences, history, and archeology where important information can be visualized. Together, the findings provide support for the use of learner-generated visual explanations as a powerful learning tool.

  11. Creating speech-synchronized animation. (United States)

    King, Scott A; Parent, Richard E


    We present a facial model designed primarily to support animated speech. Our facial model takes facial geometry as input and transforms it into a parametric deformable model. The facial model uses a muscle-based parameterization, allowing for easier integration between speech synchrony and facial expressions. Our facial model has a highly deformable lip model that is grafted onto the input facial geometry to provide the necessary geometric complexity needed for creating lip shapes and high-quality renderings. Our facial model also includes a highly deformable tongue model that can represent the shapes the tongue undergoes during speech. We add teeth, gums, and upper palate geometry to complete the inner mouth. To decrease the processing time, we hierarchically deform the facial surface. We also present a method to animate the facial model over time to create animated speech using a model of coarticulation that blends visemes together using dominance functions. We treat visemes as a dynamic shaping of the vocal tract by describing visemes as curves instead of keyframes. We show the utility of the techniques described in this paper by implementing them in a text-to-audiovisual-speech system that creates animation of speech from unrestricted text. The facial and coarticulation models must first be interactively initialized. The system then automatically creates accurate real-time animated speech from the input text. It is capable of cheaply producing tremendous amounts of animated speech with very low resource requirements.

  12. Creating a climate for excellence. (United States)

    Lancaster, J


    Some people are motivated to achieve in a manner consistent with the goals of their organization while others pursue individual goals. The attitudes people hold determine their behavior. Therefore, the manager is charged with creating an environment that fosters employee commitment to organizational goals. To create a climate for achievement, managers must recognize that all employees want recognition. Employees perform more effectively when they understand the goals of the organization, know what is expected of them, and are part of a system that includes feedback and reinforcement. Generally, people perform more effectively in an environment with minimal threat and punishment; individual responsibility should be encouraged, rewards based on results, and a climate of trust and open communication should prevail.

  13. Creating advanced health informatics certification. (United States)

    Gadd, Cynthia S; Williamson, Jeffrey J; Steen, Elaine B; Fridsma, Douglas B


    In 2005, AMIA leaders and members concluded that certification of advanced health informatics professionals would offer value to individual practitioners, organizations that hire them, and society at large. AMIA's work to create advanced informatics certification began by leading a successful effort to create the clinical informatics subspecialty for American Board of Medical Specialties board-certified physicians. Since 2012, AMIA has been working to establish advanced health informatics certification (AHIC) for all health informatics practitioners regardless of their primary discipline. In November 2015, AMIA completed the first of 3 key tasks required to establish AHIC, with the AMIA Board of Directors' endorsement of proposed eligibility requirements. This AMIA Board white paper describes efforts to establish AHIC, reports on the current status of AHIC components, and provides a context for the proposed AHIC eligibility requirements. © The Author 2016.

  16. Creating and Sustaining Competitive Advantage


    Lage Hansen, Jakob


    The paper provides a general framework for examining how governance choice affects competitive advantage. I argue that firms rely on assets for competing, and that these assets can be accessed by different governance structures (i.e., they can be in- or outsourced). The transaction cost economics framework is used to expose strengths and weaknesses of governance structures with respect to creating and sustaining competitive advantage. The result is a tradeoff to consider when choosing how to ...

  17. Preventive Indicators for Creating Brownfields

    Directory of Open Access Journals (Sweden)

    Marija Burinskienė


    Full Text Available Although the problem of brownfields in urban territories is successfully limited, it is a negative phenomenon of a sustainable city. Moreover, the number of recently created brownfield territories has become higher than that of the regenerated ones. Such territories reduce the quality of the social and economic setting of a city as well as visually and physically affect the life quality of city residents. Unfortunately, methods for the revitalization of brownfield land have been applied to deal with the consequences of the problem rather than to limit the problem itself. The authors of the article have investigated the aspects to be avoided to not create brownfields. The indicators that enable predicting the probability of a territory becoming a brownfield have been analyzed in this paper. Countries develop and exist under different social and economic conditions. Therefore, there is no uniform and universally accepted system of indicators for brownfield prevention that can be applied in any country or city. The authors have attempted to implement a recently developed idea of indicators for prevention under Lithuanian conditions and have selected those facilitating the identification of brownfields with an aim of identifying the most significant ones warning about the potential harm from the creation of brownfields in Lithuania. The selected indicators have been grouped, taking into account social, economic, natural, building and infrastructure settings of the city and ranked by a group of experts in urban planning. The established hierarchy of indicators in the groups of urban setting has allowed the authors to select the most significant preventive indicators for brownfields. The created system of indicators could be applied in practice as a basis for monitoring pertinent data and tracking their change.

  19. Creating better superconductors by periodic nanopatterning

    Directory of Open Access Journals (Sweden)

    Milan P. Allan, Mark H. Fischer, Oliver Ostojic, Arjo Andringa


    Full Text Available The quest to create superconductors with higher transition temperatures is as old as superconductivity itself. One strategy, popular after the realization that (conventional superconductivity is mediated by phonons, is to chemically combine different elements within the crystalline unit cell to maximize the electron-phonon coupling. This led to the discovery of NbTi and Nb3Sn, to name just the most technologically relevant examples. Here, we propose a radically different approach to transform a `pristine' material into a better (meta- superconductor by making use of modern fabrication techniques: designing and engineering the electronic properties of thin films via periodic patterning on the nanoscale. We present a model calculation to explore the key effects of different supercells that could be fabricated using nanofabrication or deliberate lattice mismatch, and demonstrate that specific pattern will enhance the coupling and the transition temperature. We also discuss how numerical methods could predict the correct design parameters to improve superconductivity in materials including Al, NbTi, and MgB2

  20. Creating your own leadership brand. (United States)

    Kerfoot, Karlene


    Building equity in a brand happens through many encounters. The initial attraction must be followed by the meeting of expectations. This creates a loyalty that is part of an emotional connection to that brand. This is the same process people go through when they first meet a leader and decide if this is a person they want to buy into. People will examine your style, your competence, and your standards. If you fail on any of these fronts, your ability to lead will be severely compromised. People expect more of leaders now, because they know and recognize good leaders. And, predictably, people are now more cynical of leaders because of the well-publicized excess of a few leaders who advanced their own causes at the expense of their people and their financial future. This will turn out to be a good thing, because it will create a higher standard of leadership that all must aspire to achieve. When the bar is raised for us, our standards of performance are also raised.

    Full Text Available Human beings, who perceive the reality of death however who do not know when it will happen, begin their life with this deficiency. Therefore, throughout their lives, they struggle to consummate and make up for the things that they perceive as deficiency or shortcomings through different ways. Humor is one of these means. The fact that deficiencies are eliminated results in superiority and relaxation. The sense of humor and relaxation simultaneously provide laughter. When theories of humor such as superiority, incongruous and relief are taken into consideration, it seems that these theories are related and support each other. Each text is whole with its form and content, which should be evaluated as a whole as much as possible. Hence this study dwells on shortcomings in jokes and in the lights of these shortcomings and theories of humor, it is intended tomake humor in stories, in terms of structural and semantic context, more concrete. Five stories/jokes randomly selected through samples are analyzed in this article. There are two basic types of opposition. The firstone is opposition that creates situation, the second one is thatcreates laughter. The first opposition depicts the shortcomings of knowledge, skill, patience arrogance and jealousyand prepares the second opposition. The opposition that creates laughter make up for shortcomings through cause and effect relationship and laughter comes out.

  2. Can the Universe create itself? (United States)

    Gott, J. Richard, III; Li, Li-Xin


    The question of first-cause has troubled philosophers and cosmologists alike. Now that it is apparent that our universe began in a big bang explosion, the question of what happened before the big bang arises. Inflation seems like a very promising answer, but as Borde and Vilenkin have shown, the inflationary state preceding the big bang could not have been infinite in duration-it must have had a beginning also. Where did it come from? Ultimately, the difficult question seems to be how to make something out of nothing. This paper explores the idea that this is the wrong question-that that is not how the Universe got here. Instead, we explore the idea of whether there is anything in the laws of physics that would prevent the Universe from creating itself. Because spacetimes can be curved and multiply connected, general relativity allows for the possibility of closed timelike curves (CTCs). Thus, tracing backwards in time through the original inflationary state we may eventually encounter a region of CTCs-giving no first-cause. This region of CTCs may well be over by now (being bounded toward the future by a Cauchy horizon). We illustrate that such models-with CTCs-are not necessarily inconsistent by demonstrating self-consistent vacuums for Misner space and a multiply connected de Sitter space in which the renormalized energy-momentum tensor does not diverge as one approaches the Cauchy horizon and solves Einstein's equations. Some specific scenarios (out of many possible ones) for this type of model are described. For example, a metastable vacuum inflates producing an infinite number of (big-bang-type) bubble universes. In many of these, either by natural causes or by action of advanced civilizations, a number of bubbles of metastable vacuum are created at late times by high energy events. These bubbles will usually collapse and form black holes, but occasionally one will tunnel to create an expanding metastable vacuum (a baby universe) on the other side of the

  4. Creating Genetic Resistance to HIV (United States)

    Burnett, John C.; Zaia, John A.; Rossi, John J.


    HIV/AIDS remains a chronic and incurable disease, in spite of the notable successes of highly active antiretroviral therapy. Gene therapy offers the prospect of creating genetic resistance to HIV that supplants the need for antiviral drugs. In sight of this goal, a variety of anti-HIV genes have reached clinical testing, including gene-editing enzymes, protein-based inhibitors, and RNA-based therapeutics. Combinations of therapeutic genes against viral and host targets are designed to improve the overall antiviral potency and reduce the likelihood of viral resistance. In cell-based therapies, therapeutic genes are expressed in gene modified T lymphocytes or in hematopoietic stem cells that generate an HIV-resistant immune system. Such strategies must promote the selective proliferation of the transplanted cells and the prolonged expression of therapeutic genes. This review focuses on the current advances and limitations in genetic therapies against HIV, including the status of several recent and ongoing clinical studies. PMID:22985479

  6. Creating responsible partnerships in tourism

    Directory of Open Access Journals (Sweden)

    Ana Spitzer


    Full Text Available RQ: Organisations do not provide sufficient time and effort to seek out companies for partners that would, with the assistance of responsible cooperation, contribute to better quality offers and consequently to increased income and the good reputation of both companies. Responsibilities and ethics is where organizations on bothsides would take on and accept their own norms, tasks, obligations and be aware that in a relationship there is a need to give explanations and justify one’s actions, such partnerships will be long and prosperous. This requires a great deal of knowledge and maturity together with a very important personal characteristic that is care. This study examines whether the creation of long term partnerships through responsible and more personal (friendlyrelations brings the organization to greater success.Purpose: The purpose of this research is to determine how important it is for organizations in the tourism industry to build long term relationships, what it should be based on and whether companies are willing to change the current methods of operations.Method: The method of research was an interview with individuals that had a certain position within a tourism company and had contacts with partners and were obligated to see out new ones. A paradigm model was built and the responses analysed.Results: The survey results are encouraging. The interviews showed that respondents were aware that it is necessary to have long term and responsible partnerships. They recognized that in today’s world there is a lack of collaboration that is based on understanding andthat there should be more relations on a personal level. It isrequired that this changes in the future. The participants specifically highlight financial irresponsibility in many companies that destroys collaboration.Organization: With the help of this study, the author attempts to contribute ideas to organizations on how to create solid collaboration with partners, as

  7. Adolescents and HIV: creating partnerships. (United States)

    Tierney, S


    Despite the President's directive on youth and HIV in 1997 to focus the nation's attention on adolescents and the battle against AIDS, prevention programs continue to be ineffective. The number of seropositive youth, ages 13 to 24 years old, is unclear due to inconsistent definitions of age ranges and inadequate access to testing. Youth have not sought testing for many reasons, including failing to perceive their vulnerability to HIV, confidentiality concerns, and not realizing the effectiveness of early treatment. Adolescents are creating independence, establishing relationships, and learning about drugs and alcohol. Young gay and bisexual men, drug-using youth, and youth of color are at high risk of HIV transmission. Identifying the population involved in risk-taking behavior and eliminating the behavior is an ineffective strategy for adolescent HIV prevention programs. Complicating the issue further, the goals and expectations of adolescents differ from the adults who design and deliver prevention programs. HIV education and prevention efforts need to address solutions to hopelessness, isolation, and violence, rather than focusing on the negative effects risky behaviors will have in the future. Effective programs combine a youth/adult partnership to take advantage of the strengths of each individual. Strategies for implementing prevention programs that address the specific needs of adolescents are suggested.

  8. Creating healthy and just bioregions. (United States)

    Pezzoli, Keith; Leiter, Robert Allen


    Dramatic changes taking place locally, regionally, globally, demand that we rethink strategies to improve public health, especially in disadvantaged communities where the cumulative impacts of toxicant exposure and other environmental and social stressors are most damaging. The emergent field of Sustainability Science, including a new bioregionalism for the 21st Century, is giving rise to promising place-based (territorially rooted) approaches. Embedded in this bioregional approach is an integrated planning framework (IPF) that enables people to map and develop plans and strategies that cut across various scales (e.g. from regional to citywide to neighborhood scale) and various topical areas (e.g. urban land use planning, water resource planning, food systems planning and "green infrastructure" planning) with the specific intent of reducing the impacts of toxicants to public health and the natural environment. This paper describes a case of bioregionally inspired integrated planning in San Diego, California (USA). The paper highlights food-water-energy linkages and the importance of "rooted" community-university partnerships and knowledge-action collaboratives in creating healthy and just bioregions.

    Electron-positron jets with MeV temperature are thought to be present in a wide variety of astrophysical phenomena such as active galaxies, quasars, gamma ray bursts and black holes. They have now been created in the laboratory in a controlled fashion by irradiating a gold target with an intense picosecond duration laser pulse. About 10{sup 11} MeV positrons are emitted from the rear surface of the target in a 15 to 22-degree cone for a duration comparable to the laser pulse. These positron jets are quasi-monoenergetic (E/{delta}E {approx} 5) with peak energies controllable from 3-19 MeV. They have temperatures from 1-4 MeV in the beam frame in both the longitudinal and transverse directions. Positron production has been studied extensively in recent decades at low energies (sub-MeV) in areas related to surface science, positron emission tomography, basic antimatter science such as antihydrogen experiments, Bose-Einstein condensed positronium, and basic plasma physics. However, the experimental tools to produce very high temperature positrons and high-flux positron jets needed to simulate astrophysical positron conditions have so far been absent. The MeV temperature jets of positrons and electrons produced in our experiments offer a first step to evaluate the physics models used to explain some of the most energetic phenomena in the universe.

  10. Creating experimental color harmony map (United States)

    Chamaret, Christel; Urban, Fabrice; Lepinel, Josselin


    Starting in the 17th century with Newton, color harmony is a topic that did not reach a consensus on definition, representation or modeling so far. Previous work highlighted specific characteristics for color harmony on com- bination of color doublets or triplets by means of a human rating on a harmony scale. However, there were no investigation involving complex stimuli or pointing out how harmony is spatially located within a picture. The modeling of such concept as well as a reliable ground-truth would be of high value for the community, since the applications are wide and concern several communities: from psychology to computer graphics. We propose a protocol for creating color harmony maps from a controlled experiment. Through an eye-tracking protocol, we focus on the identification of disharmonious colors in pictures. The experiment was composed of a free viewing pass in order to let the observer be familiar with the content before a second pass where we asked "to search for the most disharmonious areas in the picture". Twenty-seven observers participated to the experiments that was composed of a total of 30 different stimuli. The high inter-observer agreement as well as a cross-validation confirm the validity of the proposed ground-truth.

  11. India creates social marketing organization. (United States)


    India, in a major policy shift toward reversible birth controls methods, will form a new organization to promote private sector contraceptive sales. The government, through a recently signed agreement with the Agency for International Development (AID), plans to establish a private nonprofit Contraceptive Marketing Organization (CMO) in fiscal year 1984. This momentous move marks a full circle return to a 1969 proposal by AID and Ford Foundation consultants. Funded at about $500 million over a 7 year period, the CMO will function as a semi-autonomous entity run by a board of governors representing government and such public and public sectors as health, communications, management, manufacturing, marketing, advertising, and market research. According to the agreement called the India Family Planning Communications and Marketing Plan, the CMO's activities will cover procurement and distribution of condoms, oral contraceptives (OCs), and other yet to be determined contraceptive methods. Of the $500 million in funds, the government of India has pledged 2/3, AID roughly $50 million in grants and loans, with the balance expected from such sources as the UN Fund for Population Activities. The CMO's goal is a marked increase in contraceptive use by married couples of reproductive age from the current 6% rate to 20% by 1990. As of 1982, India has 122 million such couples, with 1% purchasing commercial products, 2% buying Nirodh Marketing Program condoms and 3% relying on free government contraceptives. Besides creating the CMO, the India/AID pact outlines intensified public sector family planning promotions and activities. Some Indian health experts believe the government's decision to expand social marketing's role rests with a significant decade long decline in the popularity of such permanent birth control measures as vasectomy and tubal ligation.

  12. Marangoni patterns (United States)

    Thyagu, N. Nirmal; Strombom, Evelyn; Palumbo, Daniel; Caicedo, Carlos; Shinbrot, Troy


    We study Marangoni patterns that emerge when common food dye is dropped into a dish of shallow water. These patterns consist of tendrils and spots that sharpen over time before eventually fading. We demonstrate that the patterns can be modeled using coupled reaction-diffusion equations, where the "reaction" terms appear due to a nonlinear dependence of surface tension on dye concentration. We show using a spatio-temporal metric that these patterns are distinct from previously described Turing patterns.

  14. Development of soil properties and nitrogen cycling in created wetlands (United States)

    Wolf, K.L.; Ahn, C.; Noe, G.B.


    Mitigation wetlands are expected to compensate for the loss of structure and function of natural wetlands within 5–10 years of creation; however, the age-based trajectory of development in wetlands is unclear. This study investigates the development of coupled structural (soil properties) and functional (nitrogen cycling) attributes of created non-tidal freshwater wetlands of varying ages and natural reference wetlands to determine if created wetlands attain the water quality ecosystem service of nitrogen (N) cycling over time. Soil condition component and its constituents, gravimetric soil moisture, total organic carbon, and total N, generally increased and bulk density decreased with age of the created wetland. Nitrogen flux rates demonstrated age-related patterns, with younger created wetlands having lower rates of ammonification, nitrification, nitrogen mineralization, and denitrification potential than older created wetlands and natural reference wetlands. Results show a clear age-related trajectory in coupled soil condition and N cycle development, which is essential for water quality improvement. These findings can be used to enhance N processing in created wetlands and inform the regulatory evaluation of mitigation wetlands by identifying structural indicators of N processing performance.

  15. Polyhedral patterns

    KAUST Repository

    Jiang, Caigui


    We study the design and optimization of polyhedral patterns, which are patterns of planar polygonal faces on freeform surfaces. Working with polyhedral patterns is desirable in architectural geometry and industrial design. However, the classical tiling patterns on the plane must take on various shapes in order to faithfully and feasibly approximate curved surfaces. We define and analyze the deformations these tiles must undertake to account for curvature, and discover the symmetries that remain invariant under such deformations. We propose a novel method to regularize polyhedral patterns while maintaining these symmetries into a plethora of aesthetic and feasible patterns.

  18. Method of patterning an aerogel (United States)

    Reed, Scott T [Edgewood, NM


    A method for producing a pattern in an aerogel disposed as a coating on a substrate comprises exposing the aerogel coating to the vapors of a hydrophobic silane compound, masking the aerogel coating with a shadow photomask and irradiating the aerogel coating with ultraviolet (UV) irradiation. The exposure to UV through the shadow mask creates a pattern of hydrophobic and hydrophilic regions in the aerogel coating. Etching away the hydrophilic regions of the aerogel coating, preferably with a 1 molar solution of sodium hydroxide, leaves the unwetted and unetched hydrophobic regions of the aerogel layer on the substrate, replicating the pattern of the photomask. The hydrophobic aerogel pattern can be further exposed to UV irradiation if desired, to create a hydrophilic aerogel pattern.

  19. Varianish: Jamming with Pattern Repetition

    Directory of Open Access Journals (Sweden)

    Jort Band


    Full Text Available In music, patterns and pattern repetition are often regarded as a machine-like task, indeed often delegated to drum Machines and sequencers. Nevertheless, human players add subtle differences and variations to repeated patterns that are musically interesting and often unique. Especially when looking at minimal music, pattern repetitions create hypnotic effects and the human mind blends out the actual pattern to focus on variation and tiny differences over time. Varianish is a musical instrument that aims at turning this phenomenon into a new musical experience for musician and audience: Musical pattern repetitions are found in live music and Varianish generates additional (musical output accordingly that adds substantially to the overall musical expression. Apart from the theory behind the pattern finding and matching and the conceptual design, a demonstrator implementation of Varianish is presented and evaluated.

  6. Geodesic patterns

    KAUST Repository

    Pottmann, Helmut


    Geodesic curves in surfaces are not only minimizers of distance, but they are also the curves of zero geodesic (sideways) curvature. It turns out that this property makes patterns of geodesics the basic geometric entity when dealing with the cladding of a freeform surface with wooden panels which do not bend sideways. Likewise a geodesic is the favored shape of timber support elements in freeform architecture, for reasons of manufacturing and statics. Both problem areas are fundamental in freeform architecture, but so far only experimental solutions have been available. This paper provides a systematic treatment and shows how to design geodesic patterns in different ways: The evolution of geodesic curves is good for local studies and simple patterns; the level set formulation can deal with the global layout of multiple patterns of geodesics; finally geodesic vector fields allow us to interactively model geodesic patterns and perform surface segmentation into panelizable parts. © 2010 ACM.

    Full Text Available The paper presents an explanation of the essence of creation of consumer communities that have been developing for several years on the marketing market. A hypothesis was made that says that the mechanism of interdependence existing in the consumer community can be used to create sustainable consumption on the market. The method of literature study was used in the article. In the introduction it was proved that regardless of whether a community is formed independently around the brand or not, its existence is initiated by a company and its members interact by providing one another with the patterns of consumption. The reasons for consumers’ belonging to communities around the brand were described. The presented literature analysis revealed that the appropriate management of the community around the brand can serve the company to create a sustainable product consumption.

  14. Synthetic biology ethically evaluated: The creating God and co-creating human

    Directory of Open Access Journals (Sweden)

    Riaan Rheeder


    Full Text Available God did not create once and then put an end to it. Testimony from Scripture shows that God continuously establishes or creates new things. Humans can therefore expect to always see and experience new things in creation. With this pattern of reasoning, one can anticipate that the human being as image of God will continuously establish new things in history. Although nature has value, it does not have absolute value and therefore it can be synthesised responsibly. The thought that humans are stewards of God is no longer adequate to, theologically put into words, the relationship human beings have with nature. New biotechnological developments ask for different answers from Scripture. Several ethicists are of the opinion that the theological construction of humans and created co-creators can help found the relationship of the human being to nature. Humans developed as God’s image evolutionary. On the one hand, this means humans themselves are a product of nature. On the other hand, the fact that humans are the image of God is also an ethical call that humans, like God, have to develop and create new things throughout history. Synthetic biology can be evaluated as technology that is possible, because humans are the image of God. However, it should, without a doubt, be executed responsibly.Sintetiese biologie eties geëvalueer: Die skeppende God en medeskeppende mens. God het nie net eenmaal geskep en daar gestop nie. Uit Skrifgetuienisse kan afgelei word dat God voortdurend nuwe dinge tot stand bring of skep. Daarom kan die mens verwag om gedurig nuwe dinge in die skepping te sien en te beleef. Hiermee saam kan verwag word dat die mens as beeld van God voortdurend nuwe dinge in die geskiedenis tot stand sal bring. Alhoewel die natuur waarde het, het dit nie absolute waarde nie en kan dus verantwoordelik gesintetiseer word. Die gedagte dat die mens rentmeester van God is, is nie meer voldoende om die mens se verhouding tot die natuur teologies te

  5. Online Access Patterns and Students

    Directory of Open Access Journals (Sweden)

    Nasir Butrous


    Full Text Available The paper follows accessing patterns of five cohorts of postgraduate students enrolled in a core unit within a master of business administration (MBA program. The unit is designed to provide numerous opportunities for student participation in Discussion Boards using Blackboard technology. Discussion Boards create numerous opportunities for interaction amongst online learners to share and exchange their experiences, creating a sense of a virtual community. Relationships between accessing patterns for each week of the semester for each student are explored in relation to their performance using course statistics generated by the Blackboard technology. Close examination of the significant differences in access patterns to the course window and its components of communication, content, and student areas reveal middle of the semester (week 7 as the common critical point that differentiates high achieving students from low achieving students. Identifying critical points provides the faculty staff member an opportunity to introduce intervention strategies in order to improve the learning experience of all the students.

  7. [Create or copy... Which is the difference?]. (United States)

    López P, Ricardo


    Creating and copying are two different processes; we must not confuse creativity with plagiarism. However, this distinction is problematic, because there is no possibility of creating from scratch, this implies that any creative act necessarily arises from accumulative experience, inevitably producing a continuity between old and new. Even so it is necessary to establish clearly the difference between creating and copying. It is not desirable that a matter of such importance remains in the nebula or that the relationship between creativity and ethics is kept unaware. There are many cases of plagiarism, but this cannot be a consolation. There is no gain when the existence of a plagiarism is ignored or concealed and less when it is unjustified.

  9. Can Physical Examination Create a Stener Lesion? (United States)

    Lankachandra, Manesha; Eggers, John P; Bogener, James W; Hutchison, Richard L


    The purpose of this study is to determine whether a Stener lesion can be created while testing stability of the ulnar collateral ligament (UCL) of the thumb. Testing was performed in a manner that reproduced clinical examination. Six fresh frozen hand and forearm specimens underwent sequential sectioning of the accessory UCL, the proper UCL, and the ulnar sagittal band. Measurements of radial deviation of the metacarpophalangeal (MCP) joint were taken with the thumb in neutral rotation, pronation and supination, both with 0 degrees and with 30 degrees of flexion of the MCP joint. Visual examination was performed to assess the presence of a Stener lesion. No Stener lesion was created in any position as long as the fascial origin of the ulnar sagittal band at the adductor pollicis longus remained intact. After creating a defect in the ulnar sagittal band, a Stener lesion was created in two specimens, but only when the thumb was flexed and supinated. Pronation provided more stability, and supination provided less stability, with one or both components cut, especially when testing at 30° of flexion. Compared to both components cut without flexion or rotation, there was a statistically significant difference in angulation with the 30 degrees of MCP joint flexion in both neutral rotation in supination. Performing a physical examination to assess the amount of instability of an ulnar collateral ligament injury did not create a Stener lesion if the exam was performed in a controlled, gentle manner with the thumb held without rotation. If the thumb is held in neutral rotation during the exam, an iatrogenic Stener lesion should not be created.

  16. Zebra rocks: compaction waves create ore deposits. (United States)

    Kelka, Ulrich; Veveakis, Manolis; Koehn, Daniel; Beaudoin, Nicolas


    Nature has a range of distinct mechanisms that cause initially heterogeneous systems to break their symmetry and form patterns. One of these patterns is zebra dolomite that is frequently hosting economically important base metal mineralization. A consistent generic model for the genesis of these periodically banded rocks is still lacking. In this contribution, we present for the first time a fully consistent mathematical model for the genesis of the pattern by coupling the reactive fluid-solid system with hydromechanics. We show that visual banding develops at a given stress and host-rock permeability indicating that the wavelength and occurrence of the pattern may be predictable for natural settings. This finding offers the exciting possibility of estimating conditions of formation of known deposits as well as forecasting potential exploration targets.

  10. Waveguides having patterned, flattened modes

    Energy Technology Data Exchange (ETDEWEB)

    Messerly, Michael J.; Pax, Paul H.; Dawson, Jay W.


    Field-flattening strands may be added to and arbitrarily positioned within a field-flattening shell to create a waveguide that supports a patterned, flattened mode. Patterning does not alter the effective index or flattened nature of the mode, but does alter the characteristics of other modes. Compared to a telecom fiber, a hexagonal pattern of strands allows for a three-fold increase in the flattened mode's area without reducing the separation between its effective index and that of its bend-coupled mode. Hexagonal strand and shell elements prove to be a reasonable approximation, and, thus, to be of practical benefit vis-a-vis fabrication, to those of circular cross section. Patterned flattened modes offer a new and valuable path to power scaling.

    Full Text Available Paper presents automated technique for creating lithologic log plots. Technique is based on three computer tools: Microsoft (MS Access program, LogPlot program, and Visual Basic (VB macros for MS Excel. MS Access ensures professional storage of lithologic data which can be in that way easier and faster entered, searched, updated, and also used for different purposes, while LogPlot provides tools for creating lithologic log plots. VB macros enable transfer of lithologic data from MS Access to LogPlot. Data stored in MS Access are exported in ASCII files which are later used by LogPlot for creation of lithologic log plots. Presented concept facilitates creation of lithologic log plots, and automated technique enables processing of a large number of data i.e. creation of lareg number lithologic log plots in a short period of time (the paper is published in Croatian.

  12. Creating a culture for information systems success

    CERN Document Server

    Belkhamza, Zakariya


    It has been widely reported that issues related to organizational context appear frequently in discussions of information systems success. The statement that the information system did not fit the behavioral context in an organization is often part of the explanation of why particular information system encountered unanticipated resistance and never met expectation. While this context has been intensively studied, we still lack evidence on how this organizational context is affecting the success of information system from a managerial action perspective. This type of managerial involvement is often neglected to the extent that it became an essential obstacle to organizational performance. The objective of Creating a Culture for Information Systems Success is to assist CIOs and IT managers on how to use their managerial actions to create a suitable cultural environment in the organization, which leads to a successful implementation of information systems.

  14. Novel device for creating continuous curvilinear capsulorhexis. (United States)

    Soylak, Mustafa


    The purpose of this paper is to develop a novel capsulorhexis system. Mechatronics Laboratory, University of Erciyes and Kayseri Maya Eye Hospital. A 3D model was created and simulations were conducted to develop a new device which was designed, fabricated and tested for continuous curvilinear capsulorhexis (CCC). The name of this system is the electro-mechanical capsulorhexis system (EMCS). The 3D model was created by using a commercial design software and a 3D printer was used to fabricate the EMCS Finite element analysis and geometrical relation tests of the EMCS for different sized lenses were performed. The results show that the EMCS is a perfect solution for capsulorhexis surgeries, without mechanical or geometrical problems. The EMCS can open the anterior lens capsule more easily and effectively than manual CCC applications and needs less experience.

  1. Cognitive abilities and creating metaphorical names

    Directory of Open Access Journals (Sweden)

    Avanesyan, Marina O.


    Full Text Available The cognitive processing of metaphor creation has been insufficiently investigated. Creating metaphors requires the ability to work in a fantastic, impossible context, using symbolic and associative means to express oneís thoughts. It has been shown recently that intelligence plays an important role in the creation of metaphors, but it is not the main factor in determining their success. The present research explores the roles of conceptual abilities, categorical abilities, and flexibility (as the factor creativity in metaphor creation. Participants (n = 38 young adults were asked to come up with names for three photos, without any special instruction to create metaphors. To classify conceptual abilities we used ìConceptual Synthesisî (M. A. Kholodnaya, 2012; to measure categorical ability we used the subtest ìSimilaritiesî (D. Wechsler, 1955; to identify the role of creativity in the metaphor process we used the test of ìUnusual Usesî (J. P. Guilford, 1960. The creation of complex metaphorical names was associated with a tendency to create highly organized mental structures and to retain them within the general semantic context (r = 0.344, p < 0.05. The tendency to create single-level situational connections was associated with a tendency to give specific names to photos (r = 0.475, p < 0.01. Photographic images proved out to be fruitful stimuli to investigate the processing of visual information. We developed a preliminary classification of names: 1 concrete; 2 situational; 3 abstract; 4 metaphorical (M1 and M2. We identified two types of metaphorical names — perceptual and complex metaphors — that relate to conceptual abilities in different ways. It is inaccurate to speak about a general concept of ìmetaphorical abilitiesî; we should differentiate the psychological mechanisms that lie at their base.

  4. Can cognitive science create a cognitive economics? (United States)

    Chater, Nick


    Cognitive science can intersect with economics in at least three productive ways: by providing richer models of individual behaviour for use in economic analysis; by drawing from economic theory in order to model distributed cognition; and jointly to create more powerful 'rational' models of cognitive processes and social interaction. There is the prospect of moving from behavioural economics to a genuinely cognitive economics. Copyright © 2014. Published by Elsevier B.V.

    Wolf, K.L.; Ahn, C.; Noe, G.B.


    natural processes over time. When examined along a hydrologic gradient, LD increased with proximity to an overflow point as a result of differential sediment deposition and erosion during flood events. Nitrification increased with T and denitrification potential increased with LD, indicating that microtopographic heterogeneity enhances coupled N fluxes. The resulting N flux patterns may be explained by the increase in oxygen availability elicited by greater T (enhancing nitrification) and by the adjacent zones of aerobic and anaerobic conditions elicited by greater LD (enhancing coupled nitrification and denitrification potential). Findings of this study support the incorporation of MT into the design and regulatory evaluation of created wetlands in order to enhance N cycling and removal. ?? 2011.

    Lansing, J Stephen; Abundo, Cheryl; Jacobs, Guy S; Guillot, Elsa G; Thurner, Stefan; Downey, Sean S; Chew, Lock Yue; Bhattacharya, Tanmoy; Chung, Ning Ning; Sudoyo, Herawati; Cox, Murray P


    Languages are transmitted through channels created by kinship systems. Given sufficient time, these kinship channels can change the genetic and linguistic structure of populations. In traditional societies of eastern Indonesia, finely resolved cophylogenies of languages and genes reveal persistent movements between stable speech communities facilitated by kinship rules. When multiple languages are present in a region and postmarital residence rules encourage sustained directional movement between speech communities, then languages should be channeled along uniparental lines. We find strong evidence for this pattern in 982 individuals from 25 villages on two adjacent islands, where different kinship rules have been followed. Core groups of close relatives have stayed together for generations, while remaining in contact with, and marrying into, surrounding groups. Over time, these kinship systems shaped their gene and language phylogenies: Consistently following a postmarital residence rule turned social communities into speech communities.

  12. Mental Snapshots: Creating an Organized Plan for Health Assessment. (United States)

    Fosbrook, Susan Curro


    Beginning nursing students enter a rapidly moving and changing health care climate. Multiple stimulations can frighten and overwhelm the student's ability to find order of essential patient information. Students need to know how to collect, process, and manage important health data accurately and efficiently in the clinical setting. An integrative method for teaching nursing students to walk into the patient's room and construct a patterned sequence of focused assessments assists students in creating an organized plan for health assessment. The Mental Snapshots Method includes three components for health assessment: (a) sequential assessment steps of the patient; (b) color-coded visual images of the patient representing a bodily condition; and (c) focused assessment questions of primary health complaint(s) with a plan for nursing care. This mental snapshots strategy employs an information processing model of sensory, memory, and motor functioning, which enable students to maintain patient quality and safety.

  15. Hybrid foundry patterns of bevel gears

    Directory of Open Access Journals (Sweden)

    Budzik G.


    Full Text Available Possibilities of making hybrid foundry patterns of bevel gears for investment casting process are presented. Rapid prototyping of gears with complex tooth forms is possible with the use of modern methods. One of such methods is the stereo-lithography, where a pattern is obtained as a result of resin curing with laser beam. Patterns of that type are applicable in precision casting. Removing of stereo-lithographic pattern from foundry mould requires use of high temperatures. Resin burning would generate significant amounts of harmful gases. In case of a solid stereo-lithographic pattern, the pressure created during gas burning may cause the mould to crack. A gas volume reduction may be achieved by using patterns of honeycomb structure. However, this technique causes a significant worsening of accuracy of stereo-lithographic patterns in respect of their dimensions and shape. In cooperation with WSK PZL Rzeszów, the Machine Design Department of Rzeszow University of Technology carried out research on the design of hybrid stereo-lithographic patterns. Hybrid pattern consists of a section made by stereo-lithographic process and a section made of casting wax. The latter material is used for stereo-lithographic pattern filling and for mould gating system. The hybrid pattern process consists of two stages: wax melting and then the burn-out of stereolithographic pattern. Use of hybrid patterns reduces the costs of production of stereolithographic patterns. High dimensional accuracy remains preserved in this process.

    Transierra is a Bolivian company created in the year 2000 with the goal of transporting natural gas from the fields of San Alberto and San Antonio, in Tarija, to the Rio Grande Gas Compression Plant in Santa Cruz, for export to Brazil. Transierra has implemented a Social Action Plan, which allowed it to execute more than 800 community projects for the benefit of over 40 thousand families living in it's area of influence, with the presence of 146 indigenous communities, generally lagging behind in economic and productive life in the region and country. The Support Program to Guarani Development Plans (PA-PDG) is part of the Social Plan and is part of a long-term agreement signed between Transierra and indigenous organizations. The program has implemented more than one hundred projects for productive development, health, education, cultural revaluation, and strengthening organizational infrastructure, generating huge benefits in improving the living conditions of thousands of families of the Guarani people. This year a unique initiative was created with 4 Indigenous Captains and with the support of the International Finance Corporation (World Bank Group), including Business Plans to promote sustainable economic growth, created productive economic cycles involving improvements to the production and productivity to enter the commercial distribution of local and national markets. These four initiatives have meant a shift in the implementation and is helping to generate new dynamics in production, in addition to capturing significant resources from public and private investment, laying the groundwork for the improvement of the incomes and quality of life of its beneficiaries.

  19. 10 ways to create shareholder value. (United States)

    Rappaport, Alfred


    Executives have developed tunnel vision in their pursuit of shareholder value, focusing on short-term performance at the expense of investing in long-term growth. It's time to broaden that perspective and begin shaping business strategies in light of the competitive landscape, not the shareholder list. In this article, Alfred Rappaport offers ten basic principles to help executives create lasting shareholder value. For starters, companies should not manage earnings or provide earnings guidance; those that fail to embrace this first principle of shareholder value will almost certainly be unable to follow the rest. Additionally, leaders should make strategic decisions and acquisitions and carry assets that maximize expected value, even if near-term earnings are negatively affected as a result. During times when there are no credible value-creating opportunities to invest in the business, companies should avoid using excess cash to make investments that look good on the surface but might end up destroying value, such as ill-advised, overpriced acquisitions. It would be better to return the cash to shareholders in the form of dividends and buybacks. Rappaport also offers guidelines for establishing effective pay incentives at every level of management; emphasizes that senior executives need to lay their wealth on the line just as shareholders do; and urges companies to embrace full disclosure, an antidote to short-term earnings obsession that serves to lessen investor uncertainty, which could reduce the cost of capital and increase the share price. The author notes that a few types of companies--high-tech start-ups, for example, and severely capital-constrained organizations--cannot afford to ignore market pressures for short-term performance. Most companies with a sound, well-executed business model, however, could better realize their potential for creating shareholder value by adopting the ten principles.

  20. How leaders create and use networks. (United States)

    Ibarra, Herman; Hunter, Mark


    Most people acknowledge that networking-creating a fabric of personal contacts to provide support, feedback, insight, and resources--is an essential activity for an ambitious manager. Indeed, it's a requirement even for those focused simply on doing their current jobs well. For some, this is a distasteful reality. Working through networks, they believe,means relying on "who you know" rather than "what you know"--a hypocritical, possibly unethical, way to get things done. But even people who understand that networking is a legitimate and necessary part of their jobs can be discouraged by the payoff--because they are doing it in too limited a fashion. On the basis of a close study of 30 emerging leaders, the authors outline three distinct forms of networking. Operational networking is geared toward doing one's assigned tasks more effectively. It involves cultivating stronger relationships with colleagues whose membership in the network is clear; their roles define them as stakeholders. Personal networking engages kindred spirits from outside an organization in an individual's efforts to learn and find opportunities for personal advancement. Strategic networking puts the tools of networking in the service of business goals. At this level, a manager creates the kind of network that will help uncover and capitalize on new opportunities for the company. The ability to move to this level of networking turns out to be a key test of leadership. Companies often recognize that networks are valuable, andthey create explicit programs to support them. But typically these programs facilitate only operational networking. Likewise, industry associations provide formal contexts for personal networking. The unfortunate effect is to give managers the impression that they know how to network and are doing so sufficiently. A sidebar notes the implication for companies' leadership development initiatives: that teaching strategic networking skills will serve their aspiring leaders and

    Tippitt, Michelle Pixley; Ard, Nell; Kline, Juanita Reese; Tilghman, Joan; Chamberlain, Barbara; Meagher, P Gail


    A number of studies related to academic dishonesty within the nursing student population have been published; however, little has been written in the nursing literature regarding academic integrity and means of promoting this value. In addition to the many short-term solutions to prevent cheating and dissuade academic misconduct that are offered, solutions that promote long-term affective changes underlying the acquisition of academic integrity are needed. This article provides a context for discussions related to academic integrity, explores issues facing faculty when dealing with this challenge, and offers short-term and long-term strategies for creating environments that foster academic integrity.

    Bruhn, J G


    Multiculturism is an ideal goal for our society, its organizations, and its institutions, involving a continuous process of education and change within organizations. Multiculturalism begins with diversity and requires various steps to achieve changes in attitudes, behaviors, and values. The leadership of organizations must not only commit to diversification, but they must participate in it and reward its efforts. Diversification should be managed by creating a climate of open participation, feedback, and control at the lower organizational levels. To micromanage the process of becoming diverse increases resistance and paranoia and counters educational efforts.

  9. Create your own stimulus: Manipulating movements according to social categories. (United States)

    Koppensteiner, Markus; Primes, Georg; Stephan, Pia


    People ascribe purposeful behaviour to the movements of artificial objects and social qualities to human body motion. We investigated how people associate simple motion cues with social categories. For a first rating-experiment we converted the body movements of speakers into stick-figure animations; for a second rating-experiment we used animations of one single dot. Rating-experiments were "reversed" because we asked participants to alter the movements (i.e., vertical amplitude, horizontal amplitude, and velocity) of the stimuli according to different instructions (e.g., create a stimulus of high dominance). Participants equipped stick figures and dot animations with expansive movements to represent high dominance. Expansive and fast movements (i.e., high velocity) were mainly associated with high aggressiveness. Fast movements were also associated with low friendliness, low trustworthiness, and low competence. Overall, patterns found for stick figure and dot animations were similar indicating that certain motion cues convey social information even when only a dot and no body form is visible. The "reverse approach" we propose here makes the impact of different components directly observable. The data generated by this method offers better insights into the interplay of these components and the ways in which they form meaningful patterns. The proposed method can be extended to other types of nonverbal cues and a variety of social categories.

  11. Creating the Medical Schools of the Future. (United States)

    Skochelak, Susan E; Stack, Steven J


    Despite wide consensus on needed changes in medical education, experts agree that the gap continues to widen between how physicians are trained and the future needs of our health care system. A new model for medical education is needed to create the medical school of the future. The American Medical Association (AMA) is working to support innovative models through partnerships with medical schools, educators, professional organizations, and accreditors. In 2013, the AMA designed an initiative to support rapid innovation among medical schools and disseminate the ideas being tested to additional medical schools. Awards of $1 million were made to 11 medical schools to redesign curricula for flexible, individualized learning pathways, measure achievement of competencies, develop new assessment tools to test readiness for residency, and implement new models for clinical experiences within health care systems. The medical schools have partnered with the AMA to create the AMA Accelerating Change in Medical Education Consortium, working together to share prototypes and participate in a national evaluation plan. Most of the schools have embarked on major curriculum revisions, replacing as much as 25% of the curriculum with new content in health care delivery and health system science in all four years of training. Schools are developing new certification in quality and patient safety and population management. In 2015, the AMA invited 21 additional schools to join the 11 founding schools in testing and disseminating innovation through the consortium and beyond.

    Sponsored by Associated Universities, Inc. (AUI) and the National Radio Astronomy Observatory (NRAO), this project creates a cultural and educational exchange program between communities in South and North America, linking San Pedro de Atacama in Chile and Magdalena, New Mexico in the United States. Both communities have similar demographics, are in relatively undeveloped regions of high-elevation desert, and are located near major international radio astronomy research facilities. The Atacama Large Millimeter/submillimeter Array (ALMA) is just 40 km east of San Pedro; the Very Large Array (VLA) is just 40 km west of Magdalena. In February 2007, the Mayor of San Pedro and two teachers visited Magdalena for two weeks; in July 2007 three teachers from Magdalena will visit San Pedro. These visits enable the communities to lay the foundation for a permanent, unique partnership. The teachers are sharing expertise and teaching methodologies for physics and astronomy. In addition to creating science education opportunities, this project offers students linguistic and cultural connections. The town of San Pedro, Chile, hosts nearly 100,000 tourists per year, and English language skills are highly valued by local students. Through exchanges enabled by email and distance conferencing, San Pedro and Magdalena students will improve English and Spanish language skills while teaching each other about science and their respective cultures.

  13. Creating a culture where employee engagement Thrives

    Energy Technology Data Exchange (ETDEWEB)

    Don Groover, C.S.P. [Behavioral Science Technology, Ojai, CA (United States)


    Safety leaders across industries face a critical challenge: engaging employees. While engagement of a few people may be easy in short-term projects, it is significantly more difficult with long-term processes. In this session we show leaders how they can create a culture where workers are more open and even eager to be involved in safety efforts. Our experience with safety leaders in the nuclear industry has verified that when the factors that drive organizational functioning are understood, leaders are enabled to augment employee engagement and attain significant improvement in safety outcomes. The underlying factors that influence employee engagement, performance, outcomes, and organizational culture are the same the world over. We will also show how safety is capable, by its intrinsic value, of winning profound support and direct engagement of employees. In this session, we will examine how leaders can leverage their decisions and actions to win over employees to safety and support them in their endeavors to promote it. Using the safety leadership best practices Vision, Credibility, Accountability, Communication, Collaboration, Action Orientation, and Recognition and Feedback, leaders increase their impact on their organization in favor of a culture that supports safety and employee engagement. Leaders that create a climate and culture where employee engagement thrives, realize better safety results. Leadership is not exclusively an inborn talent; it can be developed and enhanced. To this end, we will also show the advantages of transformational leadership style by comparing it to more classical transactional leadership.

    Full Text Available The realities of our modern society demonstrate that businesses operate in a competitive environment, which requires continuous improvement and development of production and sales. In this context, for financial, economic and fiscal reasons, companies resort to a process of concentration, through the merger of all the factors involved in the fulfilment and diversification of their activities. Often, the reasons for engaging in a merger refer to the fact that two merged companies create, in terms of value, an entity that exceeds the individual values of the two participants if they were to continue to activate separately. This paper aims at analysing whether the well-known relationship ‘1+1=3’, which describes merger synergies, applies at the Romanian level. For this reason, each of the values of 77 merged companies were compared with the sum of the individual values of the firms that initially created them. It was found that 56% of the mergers analysed generated added value for shareholders.

  15. Our Lunar Destiny: Creating a Lunar Economy (United States)

    Rohwer, Christopher J.


    "Our Lunar Destiny: Creating a Lunar Economy" supports a vision of people moving freely and economically between the earth and the Moon in an expansive space and lunar economy. It makes the economic case for the creation of a lunar space economy and projects the business plan that will make the venture an economic success. In addition, this paper argues that this vision can be created and sustained only by private enterprise and the legal right of private property in space and on the Moon. Finally, this paper advocates the use of lunar land grants as the key to unleashing the needed capital and the economic power of private enterprise in the creation of a 21st century lunar space economy. It is clear that the history of our United States economic system proves the value of private property rights in the creation of any new economy. It also teaches us that the successful development of new frontiers-those that provide economic opportunity for freedom-loving people-are frontiers that encourage, respect and protect the possession of private property and the fruits of labor and industry. Any new 21st century space and lunar economy should therefore be founded on this same principle.

    Li, Weiyang; Buford, Benjamin; Jander, Albrecht; Dhagat, Pallavi, E-mail: [School of Electrical Engineering and Computer Science, Oregon State University, Corvallis, Oregon 97331 (United States)


    A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing acoustic waves, respectively. The magnetization pattern is size-tunable, erasable, and rewritable by changing the magnetic field and acoustic power. This versatility, along with its solid-state implementation (no moving parts) and electronic control, renders it as a promising technique for application in magnetic recording, magnonic signal processing, magnetic particle manipulation, and spatial magneto-optical modulation.

  5. Creating marketing strategies for higher education institutions

    Directory of Open Access Journals (Sweden)

    Lidia Białoń


    Full Text Available The article presents a thesis that the primary premise of creating marketing strategies for higher education institution is a three-dimensional notion of marketing. The first dimension lies in the theoretical notions of the essence of marketing, including the transactional marketing (1.0, relationship marketing (2.0 and spiritual marketing (3.0. The second dimension is formed by methods of marketing research and accurate notions of marketing, while the third are channels of marketing information. Harmonizing these three dimensions is a precondition for effective marketing. Among other conditions for effective strategies there are: aligning goals of the chosen strategy with the mission of higher education institution, correct choice of targeted segments of the market and of marketing tools. The article also gives a sample classification of marketing strategies based on these criteria, with emphasis on the fact, that every higher education institution employs its own strategy.

  6. Creating Effective Dialogue Around Climate Change (United States)

    Kiehl, J. T.


    Communicating climate change to people from diverse sectors of society has proven to be difficult in the United States. It is widely recognized that difficulties arise from a number of sources, including: basic science understanding, the psychologically affect laden content surrounding climate change, and the diversity of value systems that exist in our society. I explore ways of working with the affect that arises around climate change and describe specific methods to work with the resistance often encountered when communicating this important issue. The techniques I describe are rooted in psychology and group process and provide means for creating more effective narratives to break through the barriers to communicating climate change science. Examples are given from personal experiences in presenting climate change to diverse groups.

  11. Creating biological nanomaterials using synthetic biology. (United States)

    Rice, MaryJoe K; Ruder, Warren C


    Synthetic biology is a new discipline that combines science and engineering approaches to precisely control biological networks. These signaling networks are especially important in fields such as biomedicine and biochemical engineering. Additionally, biological networks can also be critical to the production of naturally occurring biological nanomaterials, and as a result, synthetic biology holds tremendous potential in creating new materials. This review introduces the field of synthetic biology, discusses how biological systems naturally produce materials, and then presents examples and strategies for incorporating synthetic biology approaches in the development of new materials. In particular, strategies for using synthetic biology to produce both organic and inorganic nanomaterials are discussed. Ultimately, synthetic biology holds the potential to dramatically impact biological materials science with significant potential applications in medical systems.

  12. Creating a turnkey hierarchical geospatial data warehouse (United States)

    Libbey, Clinton R.


    The components of a web based data warehouse capable of populating, storing, searching, previewing, and disseminating a variety of information products over a TCP/IP network can be achieved through the use of commercially available products. The ability to deploy a solution that provides a central archive as well as distributed local archives of products is desirable. This approach is necessary due to the amount of data products generated for the community as well as the generation of custom products by regional users and the subsequent creation of their own archive for such products. Users must be able to leverage a central archive as well as have the ability to create their own local archive of data. This will increase efficiency at multiple levels and provide users with a solution that satisfies both their global data access needs and local data management.

  14. Enabling Reanalysis Intercomparison with the CREATE-IP and CREATE-V Projects (United States)

    Carriere, L.; Potter, G. L.; Hertz, J.; Shen, Y.; Britzolakis, G.; Peters, J.; Maxwell, T. P.; Li, J.; Strong, S.; Schnase, J. L.


    NASA Goddard Space Flight Center's Office of Computational and Information Sciences and Technology, the NASA Center for Climate Simulation (NCCS), and the Earth System Grid Federation (ESGF) are working together to build a uniform environment for the comparative study and use of a group of reanalysis datasets of particular importance to the research community. This effort is called the Collaborative REAnalysis Technical Environment (CREATE) and it contains two components: the CREATE-Intercomparison Project (CREATE-IP) and CREATE-V. For CREATE-IP, our target reanalyses include ECMWF ERA-Interim, NASA/GMAO MERRA and MERRA2, NOAA/NCEP CFSR, NOAA/ESRL 20CR and 20CRv2, JMA JRA25, and JRA55. Each dataset is reformatted similarly to the models in the CMIP5 archive. By repackaging the reanalysis data into a common structure and format, it simplifies access, subsetting, and reanalysis comparison. Both monthly average data and a selection of high frequency data (6-hr) relevant to investigations such as the 2016 El Niño are provided. Much of the processing workflow has been automated and new data appear on a regular basis. In collaboration with the CLIVAR Global Synthesis and Observations Panel (GSOP), we are also processing and publishing eight ocean reanalyses, from 1980 to the present. Here, the data are regridded to a common 1° x 1° grid, vertically interpolated to the World Ocean Atlas 09 (WOA09) depths, and an ensemble is generated. CREATE-V is a web based visualization tool that allows the user to simultaneously view four reanalyses to facilitate comparison. The addition of a backend analytics engine, based on UV-CDAT and Scala provides the ability to generate a time series and anomaly for any given location on a map. The system enables scientists to identify data of interest and visualize, subset, and compare data without the need for download large volumes of data for local visualization.

    Full Text Available In the highly competitive environment of the 21st century, organizations must be able to effectively change through the application of effective strategies, quickly and in a way that the competitors will be unable to imitate. Therefore, the essential question in any organization is how to achieve and maintain competitive advantage. In this regard, strategic leaders should first logically consider what will bring a substantial advantage to the organization in a long-term, and then start with the process of creating the strategy. To achieve this, researchers in the field of managerial issues offer a concept of continuous process that begins by looking at the customers pattern, through defining the competitive environment and the place of business in it and finally categorizing several strategic business conditions, as a precondition for election and creation of a competitive strategy. This process can be presented as the “funnel for selection of competitive strategy”, in whose widest part we can put the customer matrix, in the middle part we can place definitions of the business outlook of the business and the position of the organization in those perspectives. In order to implement the "Funnel method" of strategic planning teams we need accurate, timely and relevant information based on which we can bring appropriate organizational strategy. The subject of this paper is displaying the Funnel method for selection of the competitive strategy, and presentation of the situation in some of the organizations in the Pelagonija region, related to the way and the information used to create organizational strategies through the Funnel method.

  17. Creating an organizational culture for medication safety. (United States)

    Dennison, Robin Donohoe


    Medication errors are costly from human, economic, and societal perspectives. All patients are vulnerable to the detrimental effects of these errors. Recommendations regarding the problem of medication errors include: Prevention of error by learning from the nonpunitive reporting of errors and near misses; Evaluation of the system for potential causes of error through failure mode and effects analysis and encouragement of a questioning attitude; Elimination of system problems that increase the risk of error; Recognition that humans are fallible and that error will occur even in a perfect system; Minimization of the consequences of errors when they do occur. An important goal for healthcare organizations should be to create a culture that accepts the imperfection of human performance and solicits the assistance of team members in the development of safeguards for error prevention. Proposed interventions to prevent medication errors can be described by the PATIENT SAFE taxonomy, which includes: Patient participation; Adherence to established policy and procedures; Technology use; Information accessibility; Education regarding medication safety; Nonpunitive approach to reporting of errors and near misses; Teamwork, communication, and collaboration; Staffing: adequate number and staffing mix; Administration support for the clinical goal of patient safety; Failure mode and effects analysis with team member involvement; Environment and equipment to support patient safety

  18. Creating Affording Situations: Coaching through Animate Objects. (United States)

    Baber, Chris; Khattab, Ahmad; Russell, Martin; Hermsdörfer, Joachim; Wing, Alan


    We explore the ways in which animate objects can be used to cue actions as part of coaching in Activities of Daily Living (ADL). In this case, changing the appearance or behavior of a physical object is intended to cue actions which are appropriate for a given context. The context is defined by the intention of the users, the state of the objects and the tasks for which these objects can be used. We present initial design prototypes and simple user trials which explore the impact of different cues on activity. It is shown that raising the handle of a jug, for example, not only cues the act of picking up the jug but also encourages use of the hand adjacent to the handle; that combinations of lights (on the objects) and auditory cues influence activity through reducing uncertainty; and that cueing can challenge pre-learned action sequences. We interpret these results in terms of the idea that the animate objects can be used to create affording situations, and discuss implications of this work to support relearning of ADL following brain damage or injury, such as might arise following a stroke.

  20. Informational conflicts created by the waggle dance (United States)

    Grüter, Christoph; Balbuena, M. Sol; Farina, Walter M


    The honeybee (Apis mellifera) waggle dance is one of the most intriguing animal communication signals. A dancing bee communicates the location of a profitable food source and its odour. Followers may often experience situations in which dancers indicate an unfamiliar location but carry the scent of a flower species the followers experienced previously at different locations. Food scents often reactivate bees to resume food collection at previously visited food patches. This double function of the dance creates a conflict between the social vector information and the private navigational information. We investigated which kind of information followers with field experience use in this situation and found that followers usually ignored the spatial information encoded by the waggle dance even if they followed a dance thoroughly (five waggle runs or more). They relied on private information about food source locations instead (in 93% of all cases). Furthermore, foragers preferred to follow dancers carrying food odours they knew from previous field trips, independently of the spatial information encoded in the dance. Surprisingly, neither odour identity nor the location indicated by the dancer was an important factor for the reactivation success of a dance. Our results contrast with the assumption that (i) followers usually try to decode the vector information and (ii) dances indicating an unfamiliar location are of little interest to experienced foragers.

  1. Creating the Nurses' Environmental Awareness Tool (NEAT). (United States)

    Schenk, Elizabeth; Butterfield, Patricia; Postma, Julie; Barbosa-Leiker, Celestina; Corbett, Cindy


    Acute care delivery creates secondary health risks to patients, health care workers, and the environment through a complex waste stream, intensive energy use, and frequent use of harmful chemicals. Nurses are among the most affected by these risks and are also pivotal change agents in reducing the negative impacts of health care delivery. Assessing nurses' understanding of health care-associated environmental health risks is essential if care is to be delivered in an environmentally safe and healthy manner, as indicated by published professional standards of nursing practice. However, psychometrically sound instruments that measure nurses' awareness of the environmental impacts of nursing practice are not available. To address this gap, a prototype of the Nurse's Environmental Awareness Tool (NEAT) was developed. Seven content experts in environmental health nursing and/or psychometrics were asked to review draft items. Comments were analyzed and applied to the scale items. Several revisions from the original item pool were made. The resulting draft NEAT includes six subscales, in three paired subsets. This article provides a summary of the process of item development and scale design. These findings, although preliminary, provide a foundation for subsequent psychometric testing. The result of this study is the creation of an instrument to measure nurses' awareness of and behaviors associated with the environmental impact of their practices. © 2015 The Author(s).

  2. Creating the optimal conditions for rehabilitation research. (United States)

    Bakheit, Abdel Magid


    Current evidence suggests that productivity in biomedical research depends on the support that the research group enjoys from its parent institution, the composition of the group and the personal attributes of its members and leader. Supportive institutions provide adequate physical resources and allow substantial uninterrupted time for research. The effectiveness of the research group asa whole is also strongly influenced by the group's structure, the professional competence of the group leader, his leadership style and his ability to foster collaboration with other research groups and organizations. There is a good case for a flexible leadership style that is modelled on the situational theory of leadership. In addition, the personal characteristics of the individual members of the research group influence the quality and quantity of the research output. Effective groups are made of motivated individuals with research training and skills that are relevant to the objectives of the research group. Rehabilitation research is fundamentally different from traditional biomedical research. This study discusses how the factors that influence productivity of biomedical research relate to rehabilitation science and practice and examines the conditions that are necessary to create and maintain an academic environment that is conducive to large volume,high-quality research in rehabilitation medicine.

  3. Creating a Universe, a Conceptual Model

    James R. Johnson


    Full Text Available Space is something. Space inherently contains laws of nature: universal rules (mathematics, space dimensions, types of forces, types of fields, and particle species, laws (relativity, quantum mechanics, thermodynamics, and electromagnetism and symmetries (Lorentz, Gauge, and symmetry breaking. We have significant knowledge about these laws of nature because all our scientific theories assume their presence. Their existence is critical for developing either a unique theory of our universe or more speculative multiverse theories. Scientists generally ignore the laws of nature because they “are what they are” and because visualizing different laws of nature challenges the imagination. This article defines a conceptual model separating space (laws of nature from the universe’s energy source (initial conditions and expansion (big bang. By considering the ramifications of changing the laws of nature, initial condition parameters, and two variables in the big bang theory, the model demonstrates that traditional fine tuning is not the whole story when creating a universe. Supporting the model, space and “nothing” are related to the laws of nature, mathematics and multiverse possibilities. Speculation on the beginning of time completes the model.

  5. Creating healthy work environments: a strategic perspective. (United States)

    Adamson, Bonnie J


    Although I find Graham Lowe and Ben Chan's logic model and work environment metrics thought provoking, a healthy work environment framework must be more comprehensive and consider the addition of recommended diagnostic tools, vehicles to deliver the necessary change and a sustainability strategy that allows for the tweaking and refinement of ideas. Basic structure is required to frame and initiate an effective process, while allowing creativity and enhancements to be made by organizations as they learn. I support the construction of a suggested Canadian health sector framework for measuring the health of an organization, but I feel that organizations need to have some freedom in that design and the ability to incorporate their own indicators within the established proven drivers. Reflecting on my organization's experience with large-scale transformation efforts, I find that emotional intelligence along with formal leadership development and front-line engagement in Lean process improvement activities are essential for creating healthy work environments that produce the balanced set of outcomes listed in my hospital's Balanced Scorecard.

    Duggan, Anne; Minkovitz, Cynthia S; Chaffin, Mark; Korfmacher, Jon; Brooks-Gunn, Jeanne; Crowne, Sarah; Filene, Jill; Gonsalves, Kay; Landsverk, John; Harwood, Robin


    Home visiting can play a key role in the early childhood system of services. For home visiting to achieve its potential, decision-makers must make informed choices regarding adoption, adaptation, coordination, scale-up, and sustainment. We need a coordinated, focused, and theory-based home visiting research infrastructure to inform such decisions. The transdisciplinary Home Visiting Research Network (HVRN) was established in July 2012 with funding from the Health Resources and Services Administration. Its goal is to promote the translation of research findings into policy and practice. Its objectives are to (1) develop a national home visiting research agenda, (2) advance the use of innovative research methods; and (3) provide a research environment that is supportive of the professional development of emerging researchers interested in home visiting. A Management Team designs and directs activities to achieve these objectives through Work Teams. A Steering Committee of national leaders representing stakeholder groups oversees progress. HVRN's Coordinating Center supports the Work Teams and HVRN's Home visiting Applied Research Collaborative, a practice-based research network of home visiting programs. This article describes HVRN's rationale, approach, and anticipated products. We use home visiting-primary care coordination as an illustration, noting potential roles for pediatric practices and pediatric researchers and research educators in HVRN activities. HVRN creates the infrastructure for a rigorous program of research to inform policy and practice on home visiting as part of the system of services to improve family functioning, parenting, and child outcomes.

Bearing this in mind, we created a series of lessons for 3rd-5th grades using a cross-disciplinary approach to teaching about the aurora by incorporating stories, photos, movies, and geography into the science in order to paint a broad picture and answer the question, “why do we care?” The fundamental backbone of the program is literacy. Students write and illustrate fiction and non-fiction work, poetry, and brochures that solidify both language arts skills and science content. In a time when elementary teachers relegate science to less than one hour per week, we have developed a novel science program that can be easily integrated with other topics during the typical school day to increase the amount of science taught in a school year. We are inspiring students to take an interest in the natural world with this program, a stepping-stone for larger things.

  8. Creating cultures of excellence: Strategies and outcomes

    Directory of Open Access Journals (Sweden)

    Michael Mintrom


    Full Text Available Research findings on effective support for learning, the development of expertise, and the psychology of success suggest that the pursuit of excellence is teachable. Within the emerging field of research and practice termed “the scholarship of teaching and learning,” considerable effort has been made to document the practices of teachers who, by various measures, have been deemed excellent. In contrast, no effort has been made to codify how students can be trained to self-consciously build behaviors that generate excellent outcomes. This article reports on a multi-year effort to create cultures of excellence among cohorts of graduate students. A statistical analysis of subsequent student performance on a significant, related task indicates that explicitly promoting a culture of excellence among course participants can have a positive and sustained impact on their individual practices. Comments from subsequent student reflections further support this claim. The teaching strategies reported here could be refined, replicated, and reinvented to good effect across higher education. They are also of special relevance to those delivering professional development training to early- and mid-career professionals.

  9. Creating conditions for cooperative learning: Basic elements

    Ševkušić-Mandić Slavica G.


    Full Text Available Although a large number of research evidence speak out in favor of cooperative learning, its effectiveness in teaching does not depend only on teacher’s and students’ enthusiasm and willingness to work in such a manner. Creating cooperative situations in learning demands a serious preparation and engagement on the part of teacher who is structuring various aspects of work in the classroom. Although there exist a large number of models and techniques of cooperative learning, which vary in the way in which students work together, in the structure of learning tasks as well as in the degree to which cooperative efforts of students are coupled with competition among groups, some elements should be present in the structure of conditions irrespective of the type of group work in question. Potential effects of cooperation are not likely to emerge unless teachers apply five basic elements of cooperative structure: 1. structuring of the learning task and students’ positive interdependence, 2. individual responsibility, 3. upgrading of "face to face" interaction, 4. training of students’ social skills, and 5. evaluation of group processes. The paper discusses various strategies for establishing the mentioned elements and concrete examples for teaching practice are provided, which should be of assistance to teachers for as much successful cooperative learning application as possible in work with children.

  10. Creating Web Services from Community Sourced Data (United States)

    Siegel, D.; Scopel, C.; Boghici, E.


    In order to extend the World Hydro Basemap and build watershed delineation and river tracing services that cover the entire planet, we are integrating community-contributed data into a global hydrographic dataset. This dataset is the engine behind a foundational set of tools and services intended to enable hydrologic analysis on the web. However, each organization that collects hydrography uses a workflow and data model unique to their mission, which makes synthesizing their data difficult. Furthermore, these data are collected at different resolutions, so running analytics across regions with multiple contributors is not necessarily valid. Thus, instead of merging contributed data into a seamless geodatabase, the goal of our Community Maps for Hydrology program is to create workflows for converting any arbitrary dataset into the Arc Hydro Data Model. This way, tools and services can be pointed towards different contributions interchangeably while still maintaining the autonomy of each dataset. Contributors retain ownership of their data and are responsible for updates and edits, but the tools and services work identically across all contributions. HydroSHEDs data, contributed by the World Wildlife Fund, is used at the smallest scales to ensure global coverage, and national datasets extend our services to the medium-scales where available. A workflow to incorporate LIDAR and other large scale data is being developed as well, so that local governments and engineering companies can contribute to the program.

  11. Food web heterogeneity and succession in created saltmarshes (United States)

    Nordstrom, M C; Demopoulos, Amanda W.J.; Whitcraft, CR; Rismondo, A.; McMillan, P.; Gonzales, J P; Levin, L A


    1. Ecological restoration must achieve functional as well as structural recovery. Functional metrics for reestablishment of trophic interactions can be used to complement traditional monitoring of structural attributes. In addition, topographic effects on food web structure provide added information within a restoration context; often, created sites may require spatial heterogeneity to effectively match structure and function of natural habitats. 2. We addressed both of these issues in our study of successional development of benthic food web structure, with focus on bottom–up driven changes in macroinvertebrate consumer assemblages in the salt marshes of the Venice Lagoon, Italy. We combined quantified estimates of the changing community composition with stable isotope data (13C:12C and 15N:14N) to compare the general trophic structure between created (2–14 years) marshes and reference sites and along topographic elevation gradients within salt marshes. 3. Macrofaunal invertebrate consumers exhibited local, habitat-specific trophic patterns. Stable isotope-based trophic structure changed with increasing marsh age, in particular with regards to mid-elevation (Salicornia) habitats. In young marshes, the mid-elevation consumer signatures resembled those of unvegetated ponds. The mid elevation of older and natural marshes had a more distinct Salicornia-zone food web, occasionally resembling that of the highest (Sarcocornia-dominated) elevation. In summary, this indicates that primary producers and availability of vascular plant detritus structure consumer trophic interactions and the flow of carbon. 4. Functionally different consumers, subsurface-feeding detritivores (Oligochaeta) and surface grazers (Hydrobia sp.), showed distinct but converging trajectories of isotopic change over time, indicating that successional development may be asymmetric between ‘brown’ (detrital) guilds and ‘green’ (grazing) guilds in the food web. 5.

  12. Creating Active Device Materials for Nanoelectronics Using Block Copolymer Lithography. (United States)

    Cummins, Cian; Bell, Alan P; Morris, Michael A


    The prolonged and aggressive nature of scaling to augment the performance of silicon integrated circuits (ICs) and the technical challenges and costs associated with this has led to the study of alternative materials that can use processing schemes analogous to semiconductor manufacturing. We examine the status of recent efforts to develop active device elements using nontraditional lithography in this article, with a specific focus on block copolymer (BCP) feature patterning. An elegant route is demonstrated using directed self-assembly (DSA) of BCPs for the fabrication of aligned tungsten trioxide (WO₃) nanowires towards nanoelectronic device application. The strategy described avoids conventional lithography practices such as optical patterning as well as repeated etching and deposition protocols and opens up a new approach for device development. Nanoimprint lithography (NIL) silsesquioxane (SSQ)-based trenches were utilized in order to align a cylinder forming poly(styrene)-block-poly(4-vinylpyridine) (PS-b-P4VP) BCP soft template. We outline WO₃ nanowire fabrication using a spin-on process and the symmetric current-voltage characteristics of the resulting Ti/Au (5 nm/45 nm) contacted WO₃ nanowires. The results highlight the simplicity of a solution-based approach that allows creating active device elements and controlling the chemistry of specific self-assembling building blocks. The process enables one to dictate nanoscale chemistry with an unprecedented level of sophistication, forging the way for next-generation nanoelectronic devices. We lastly outline views and future research studies towards improving the current platform to achieve the desired device performance.

  14. Creating supportive environments for AIDS prevention. (United States)


    The World Health Organization's Global Programme on AIDS (GPA) argues that AIDS prevention requires a supportive environment, but that discriminatory laws make marginalized people even more vulnerable to sexually transmitted diseases (STDs). A country's legal, economic, and social environments can influence the pandemic. A short-term measure could be prostitutes collectively insisting that their clients wear condoms. Long-term measures of AIDS prevention require the improvement of the legal status of women and their access to education. Societies repress or tolerate drug use, prostitution, homosexuality, and casual sex, but often ministries forbid condom advertising, and condom possession by women can be used as evidence of prostitution. Fear of mandatory testing and detention prevents sex workers and drug users from accepting condoms and needles. A recent review of policies in 22 locations around the world found low seroprevalence of HIV among IV drug users in only 5 countries -- exactly the same countries where IV drug users had legal access to sterile needles. In Zambia a national condom promotion campaign was launched only after a 2-year debate, while free condoms had been distributed surreptitiously by a nongovernmental organization. Sex discrimination in many countries forces women to trade sex for money to make a living, and women in sex work are very vulnerable to HIV infection. Overcoming the subordination of women is a long-term undertaking, but an example of successful short-term empowerment of women is a credit scheme operated by a bank for rural women in Bangladesh. Socially, culturally, and economically male infidelity is often condoned, creating the risk of HIV infection and of passing the infection on to wives. Information campaigns stressing shared responsibility can be effective in changing social norms. Some traditional practices, e.g., ritual cleansing in Uganda and Zambia, also expose participants to the risk of HIV infection.

    Full Text Available The purpose of this paper is to analyze whether civil society itself can enhance or stimulate the creation of social entrepreneurs, by studying the traits of the civil society and the various definitions attributed to it. The main question that the paper wants to answer to is Does civil society create social entrepreneurs and the main approach used in this research paper is the theoretical one. By studying existing articles and books on the topic, the paper tries to emphasize the various dimensions that civil society can embrace, as pictured by various authors, as well as how these dimensions can relate to social entrepreneurs and the emergence of social businesses. The paper is not meant to be a breakthrough in the field, but rather to launch a question that is related to very important topics these days, social entrepreneurship, social innovation, social businesses and their connection to a very much debated topic-civil society. The paper is work-in progress and wants to stimulate research regarding the search of the sources of social entrepreneurship, in order to analyze them and better establish them as incubators for the future. It wants to be of use to whoever is researching the concepts illustrated above, as well as for those who want to get in touch with the new buzz words of the academic and entrepreneurial fields. The hereby paper stands, as previously stated, in a theoretical framework and the findings represent a mere analysis of the cause-effect relationship between the characteristics of civil society and those of social entrepreneurs. However, we are of the opinion that it can be a very good starting point for the ones interested in the domain, to analyze more sources of social entrepreneurship or further refine the answer to the question addressed in this article.

  16. Defectors Can Create Conditions That Rescue Cooperation.

    Directory of Open Access Journals (Sweden)

    Adam James Waite


    Full Text Available Cooperation based on the production of costly common goods is observed throughout nature. This is puzzling, as cooperation is vulnerable to exploitation by defectors which enjoy a fitness advantage by consuming the common good without contributing fairly. Depletion of the common good can lead to population collapse and the destruction of cooperation. However, population collapse implies small population size, which, in a structured population, is known to favor cooperation. This happens because small population size increases variability in cooperator frequency across different locations. Since individuals in cooperator-dominated locations (which are most likely cooperators will grow more than those in defector-dominated locations (which are most likely defectors, cooperators can outgrow defectors globally despite defectors outgrowing cooperators in each location. This raises the possibility that defectors can lead to conditions that sometimes rescue cooperation from defector-induced destruction. We demonstrate multiple mechanisms through which this can occur, using an individual-based approach to model stochastic birth, death, migration, and mutation events. First, during defector-induced population collapse, defectors occasionally go extinct before cooperators by chance, which allows cooperators to grow. Second, empty locations, either preexisting or created by defector-induced population extinction, can favor cooperation because they allow cooperator but not defector migrants to grow. These factors lead to the counterintuitive result that the initial presence of defectors sometimes allows better survival of cooperation compared to when defectors are initially absent. Finally, we find that resource limitation, inducible by defectors, can select for mutations adaptive to resource limitation. When these mutations are initially present at low levels or continuously generated at a moderate rate, they can favor cooperation by further reducing local

  17. Creating Porcine Biomedical Models Through Recombineering

    Directory of Open Access Journals (Sweden)

    Lawrence B. Schook


    Full Text Available Recent advances in genomics provide genetic information from humans and other mammals (mouse, rat, dog and primates traditionally used as models as well as new candidates (pigs and cattle. In addition, linked enabling technologies, such as transgenesis and animal cloning, provide innovative ways to design and perform experiments to dissect complex biological systems. Exploitation of genomic information overcomes the traditional need to choose naturally occurring models. Thus, investigators can utilize emerging genomic knowledge and tools to create relevant animal models. This approach is referred to as reverse genetics. In contrast to ‘forward genetics’, in which gene(s responsible for a particular phenotype are identified by positional cloning (phenotype to genotype, the ‘reverse genetics’ approach determines the function of a gene and predicts the phenotype of a cell, tissue, or organism (genotype to phenotype. The convergence of classical and reverse genetics, along with genomics, provides a working definition of a ‘genetic model’ organism (3. The recent construction of phenotypic maps defining quantitative trait loci (QTL in various domesticated species provides insights into how allelic variations contribute to phenotypic diversity. Targeted chromosomal regions are characterized by the construction of bacterial artificial chromosome (BAC contigs to isolate and characterize genes contributing towards phenotypic variation. Recombineering provides a powerful methodology to harvest genetic information responsible for phenotype. Linking recombineering with gene-targeted homologous recombination, coupled with nuclear transfer (NT technology can provide ‘clones’ of genetically modified animals.

  18. Peculiarities of Creating Foreign Students’ Lexical Competence

    Directory of Open Access Journals (Sweden)

    Aigul Eskermesovna Sadenova


    Full Text Available Teaching of vocabulary includes several aspects of teaching content: linguistic, methodological and psychological. Teaching of vocabulary is a process which is inextricably entwined with understanding relations between new words and phonetic and grammar aspects of the language. On the one hand, simultaneous learning of two languages complicates the tasks set to the students, but, on the other hand, it simplifies the process. The complexity is in the scope of vocabulary to be remembered, as well as in the differences between grammar structures used in Russian and Kazakh. The simplification is in the fact that students are fully aware that lexical competence is formed gradually, and that every language has its lexical base required at the initial stage, and that such base is to be developed for mastering a specific language. Before identifying the methods of vocabulary semantization in the course of teaching a language to foreign students, students shall be offered active vocabulary, used to express their ideas orally and in written form, and passive vocabulary, used to perceive oral and written information. It is not possible to teach semantics only. It is necessary to create paradigmatic, syntactic and associative relations. The formation of lexical skills is connected with the solidity of vocabulary retention. In order to ensure reinforcement of the vocabulary learnt, the students shall be offered exercises contributing to the development of their skills of using vocabulary in listening, speaking, reading and writing. All above mentioned types of vocabulary semantization constitute a unified whole. Different ways of semantization are set forth for methodological purposes, to facilitate the achievement of the desired result. Translation and non-translation techniques for vocabulary presentation, as well as some tips and exercises, are given. The use of basic vocabulary at elementary and advanced levels is suggested. Certain methods for the

  19. Leadership in creating accountable care organizations. (United States)

    Anderson, Gerard F


    General internists need to take an active leadership position in the creation of accountable care organizations (ACOs). The basic idea behind ACOs is relatively simple. Physicians, hospitals, and other health care providers will continue to be paid fee-for-service by the Medicare program, but if they can work together to better manage people with chronic conditions, reduce avoidable complications, reduce unnecessary specialty referrals, and improve transfer of beneficiaries as they transition from one care provider to another; then there is the possibility of shared savings with the Medicare program. ACOs are likely to alter existing referral patterns among general internists and specialty physicians and engender debates over how to allocate any financial savings. They are scheduled to begin operation on January 2012. As ACOs are established, general internists should review the operation of the care management and disease management programs. They should understand the financial arrangements and quality indicators that the ACOs establish. They should be involved in identifying the patients that would benefit from better care management. They should identify changes in care processes and payment reforms that would improve the care for these patients. ACOs represent an opportunity for general internists to change the way medical care is delivered.

    We examine the use of automatic adaptation to the user’s grasp and facial direction in interaction with a game. Two experimental studies were conducted. The first experiment identified patterns in grasp and facial direction that can be used as objective indicators of intentions and attention....... In the second experiment, we used the patterns identified in experiment 1 to create a game that adapted to grasp and facial direction. We compared two adaptive games to a purely command-based game. The results show that the participants in the adaptive versions of the game were significantly faster and made...

    Sculpture of gas and dust hi-res Size hi-res: 125 Kb Credits: ESA, NASA, HEIC and The Hubble Heritage Team (STScI/AURA) Dying star creates sculpture of gas and dust The so-called Cat's Eye Nebula, formally catalogued NGC 6543 and seen here in this detailed view from the NASA/ESA Hubble Space Telescope, is one of the most complex planetary nebulae ever seen in space. A planetary nebula forms when Sun-like stars gently eject their outer gaseous layers to form bright nebulae with amazing twisted shapes. Hubble first revealed NGC 6543's surprisingly intricate structures including concentric gas shells, jets of high-speed gas and unusual shock-induced knots of gas in 1994. This new image, taken with Hubble's Advanced Camera for Surveys (ACS), reveals the full beauty of a bull's-eye pattern of eleven or more concentric rings, or shells, around the Cat’s Eye. Each ‘ring’ is actually the edge of a spherical bubble seen projected onto the sky - which is why it appears bright along its outer edge.

  2. Microbial bebop: creating music from complex dynamics in microbial ecology. (United States)

    Larsen, Peter; Gilbert, Jack


    In order for society to make effective policy decisions on complex and far-reaching subjects, such as appropriate responses to global climate change, scientists must effectively communicate complex results to the non-scientifically specialized public. However, there are few ways however to transform highly complicated scientific data into formats that are engaging to the general community. Taking inspiration from patterns observed in nature and from some of the principles of jazz bebop improvisation, we have generated Microbial Bebop, a method by which microbial environmental data are transformed into music. Microbial Bebop uses meter, pitch, duration, and harmony to highlight the relationships between multiple data types in complex biological datasets. We use a comprehensive microbial ecology, time course dataset collected at the L4 marine monitoring station in the Western English Channel as an example of microbial ecological data that can be transformed into music. Four compositions were generated ( from L4 Station data using Microbial Bebop. Each composition, though deriving from the same dataset, is created to highlight different relationships between environmental conditions and microbial community structure. The approach presented here can be applied to a wide variety of complex biological datasets.

    curriculum, and the factors limiting inquiry. NBCT classroom science inquiry environment were not correlated with science teacher perceptions. They were, however, strongly correlated with science teacher attendance at science workshops and negatively correlated with teacher perception that experience limits inquiry. The results of this study have implications for policy, practice, and research. Having a science teacher who is an NBCT appears to benefit high school students; however, the benefit for students of middle school science NBCTs appears only when the teacher is also experienced. Additionally, science NBCTs appear to be able to create more controlled science inquiry learning environments than do science non-NBCTs. At the high school level the practice of using data to explain patterns appears to positively affect student science reasoning. Implications results of this study have for further research include examining the differences of the NBPTS certification process for middle and high school teachers; deeper investigation of the causes of the differences in science reasoning between students of NBCTs and non-NBCTs; and studies of the relationship between the NBPTS certification process and teacher efficacy and personal agency.

  5. Patterning nanocrystals using DNA

    Energy Technology Data Exchange (ETDEWEB)

    Williams, Shara Carol [Univ. of California, Berkeley, CA (United States)


    One of the goals of nanotechnology is to enable programmed self-assembly of patterns made of various materials with nanometer-sized control. This dissertation describes the results of experiments templating arrangements of gold and semiconductor nanocrystals using 2'-deoxyribonucleic acid (DNA). Previously, simple DNA-templated linear arrangements of two and three nanocrystals structures have been made.[1] Here, we have sought to assemble larger and more complex nanostructures. Gold-DNA conjugates with 50 to 100 bases self-assembled into planned arrangements using strands of DNA containing complementary base sequences. We used two methods to increase the complexity of the arrangements: using branched synthetic doublers within the DNA covalent backbone to create discrete nanocrystal groupings, and incorporating the nanocrystals into a previously developed DNA lattice structure [2][3] that self-assembles from tiles made of DNA double-crossover molecules to create ordered nanoparticle arrays. In the first project, the introduction of a covalently-branched synthetic doubler reagent into the backbone of DNA strands created a branched DNA ''trimer.'' This DNA trimer templated various structures that contained groupings of three and four gold nanoparticles, giving promising, but inconclusive transmission electron microscopy (TEM) results. Due to the presence of a variety of possible structures in the reaction mixtures, and due to the difficulty of isolating the desired structures, the TEM and gel electrophoresis results for larger structures having four particles, and for structures containing both 5 and 10 nm gold nanoparticles were inconclusive. Better results may come from using optical detection methods, or from improved sample preparation. In the second project, we worked toward making two-dimensional ordered arrays of nanocrystals. We replicated and improved upon previous results for making DNA lattices, increasing the size of the lattices

  6. Creating Time: Social Collaboration in Music Improvisation. (United States)

    Walton, Ashley E; Washburn, Auriel; Langland-Hassan, Peter; Chemero, Anthony; Kloos, Heidi; Richardson, Michael J


    Musical collaboration emerges from the complex interaction of environmental and informational constraints, including those of the instruments and the performance context. Music improvisation in particular is more like everyday interaction in that dynamics emerge spontaneously without a rehearsed score or script. We examined how the structure of the musical context affords and shapes interactions between improvising musicians. Six pairs of professional piano players improvised with two different backing tracks while we recorded both the music produced and the movements of their heads, left arms, and right arms. The backing tracks varied in rhythmic and harmonic information, from a chord progression to a continuous drone. Differences in movement coordination and playing behavior were evaluated using the mathematical tools of complex dynamical systems, with the aim of uncovering the multiscale dynamics that characterize musical collaboration. Collectively, the findings indicated that each backing track afforded the emergence of different patterns of coordination with respect to how the musicians played together, how they moved together, as well as their experience collaborating with each other. Additionally, listeners' experiences of the music when rating audio recordings of the improvised performances were related to the way the musicians coordinated both their playing behavior and their bodily movements. Accordingly, the study revealed how complex dynamical systems methods (namely recurrence analysis) can capture the turn-taking dynamics that characterized both the social exchange of the music improvisation and the sounds of collaboration more generally. The study also demonstrated how musical improvisation provides a way of understanding how social interaction emerges from the structure of the behavioral task context.

    Bertrand edu Castel


    Full Text Available In his 2012 book How to Create a Mind, Ray Kurzweil defines a Pattern Recognition Theory of Mind that states that the brain uses millions of pattern recognizers, plus modules to check, organize, and augment them. In this article, I further the theory to go beyond pattern recognition and include also pattern activation, thus encompassing both sensory and motor functions. In addition, I treat checking, organizing, and augmentation as patterns of patterns instead of separate modules, therefore handling them the same as patterns in general. Henceforth I put forward a unified theory I call Pattern Activation/Recognition Theory of Mind. While the original theory was based on hierarchical hidden Markov models, this evolution is based on their precursor: stochastic grammars. I demonstrate that a class of self-describing stochastic grammars allows for unifying pattern activation, recognition, organization, consistency checking, metaphor, and learning, into a single theory that expresses patterns throughout. I have implemented the model as a probabilistic programming language specialized in activation/recognition grammatical and neural operations. I use this prototype to compute and present diagrams for each stochastic grammar and corresponding neural circuit. I then discuss the theory as it relates to artificial network developments, common coding, neural reuse, and unity of mind, concluding by proposing potential paths to validation.

    Full Text Available The main focus of this note is the case of Roseveare v Katmer, Katmer v Roseveare 2013 ZAGPJHC 18, which provides an interesting (though possibly constitutionally problematic perspective to the encroachment problem. The decision in this case has opened the door for courts to create servitudes in instances where encroachments are left intact based on policy reasons. Concerning these policy reasons, the note investigates the reasonableness standard as it was applied in the case. It is argued that it is important to differentiate between the applications of reasonableness in encroachment cases and alleged nuisance disputes. The decision in this case creates the impression that courts may now order that a servitude be registered in favour of the encroacher against the affected landowner’s property. It seems as though the court had in mind the creation of a praedial servitude to justify the continued existence of the encroachment. The servitude is created by court order against the will of the affected landowner. At common law, the creation of a servitude in this respect does not exist, and the authority from which the power derives to make an order like this is not entirely clear. The court also does not provide any authority for the creation of the servitude in favour of the encroacher. Consequently, it is argued that this may have serious constitutional implications. For one, lack of authority for the deprivation that results may be unconstitutional because there is no law of general application that authorises the deprivation in terms of section 25(1. The creation of a servitude to explain the continued existence of the encroachment is not automatically included in the general discretion to replace removal with compensation. It is contended that an order that forces the affected landowner to register a servitude in favour of the encroacher to preserve the existing encroachment situation will be in conflict with section 25(1 as far as the common

  14. How does the brain create rhythms? (United States)

    Szirmai, Imre


    ornaments also follow the rule of the gothic construction, that is: pursuit of harmony towards the single one rising from the unification of 8-4-2 classes. Leibnitz concerned music as the unconscious mathematics of the soul. Movement-initiating effect of music is used in rehabilitation of patients with movement disorders. The meter and rhythm have superiority over the melody. It is possible that rhythmic movements can be generated also in the absence of sensory input and the central oscillators can produce "fictive motor patterns".

  15. Merging Galaxies Create a Binary Quasar (United States)


    Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies. Quasars are the extremely bright centers of galaxies surrounding super-massive black holes, and binary quasars are pairs of quasars bound together by gravity. Binary quasars, like other quasars, are thought to be the product of galaxy mergers. Until now, however, binary quasars have not been seen in galaxies that are unambiguously in the act of merging. But images of a new binary quasar from the Carnegie Institution's Magellan telescope in Chile show two distinct galaxies with "tails" produced by tidal forces from their mutual gravitational attraction. "This is really the first case in which you see two separate galaxies, both with quasars, that are clearly interacting," says Carnegie astronomer John Mulchaey who made observations crucial to understanding the galaxy merger. Most, if not all, large galaxies, such as our galaxy the Milky Way, host super-massive black holes at their centers. Because galaxies regularly interact and merge, astronomers have assumed that binary super-massive black holes have been common in the Universe, especially during its early history. Black holes can only be detected as quasars when they are actively accreting matter, a process that releases vast amounts of energy. A leading theory is that galaxy mergers trigger accretion, creating quasars in both galaxies. Because most such mergers would have happened in the distant past, binary quasars and their associated galaxies are very far away and therefore difficult for most telescopes to resolve. The binary quasar, labeled SDSS J1254+0846, was initially detected by the Sloan Digital Sky Survey, a large scale astronomical survey of galaxies and over 120,000 quasars.

  1. Online Access Patterns and Students' Performance

    Directory of Open Access Journals (Sweden)

    Nasir Butrous


    Full Text Available The paper follows accessing patterns of five cohorts of postgraduate students enrolled in a core unit within a master of business administration (MBA program. The unit is designed to provide numerous opportunities for student participation in Discussion Boards using Blackboard technology. Discussion Boards create numerous opportunities for interaction amongst online learners to share and exchange their experiences, creating a sense of a virtual community. Relationships between accessing patterns for each week of the semester for each student are explored in relation to their performance using course statistics generated by the Blackboard technology. Close examination of the significant differences in access patterns to the course window and its components of communication, content, and student areas reveal middle of the semester (week 7 as the common critical point that differentiates high achieving students from low achieving students. Identifying critical points provides the faculty staff member an opportunity to introduce intervention strategies in order to improve the learning experience of all the students.

  4. Colloidal transport in complex potential energy landscapes created with light (United States)

    Ladavac, Kosta

    This thesis describes experimental studies of the overdamped transport of colloidal spheres moving through structured potential energy landscapes, precisely tailored with computer-generated holograms. In static landscapes, we demonstrate optical fractionation, a continuous and continuously optimized sorting technique, which can sort mixtures of colloidal particles by size and other properties. Separation is based on the ability of a periodic landscape to deflect trajectories away from the direction of an externally applied driving force. We show that the crossover from free-flowing to deflected transport can depend exponentially on an object's size, with this exceptional selectivity emerging from the periodicity of the environment. Next we describe colloidal motion induced by a dynamic potential energy landscape, a cycle of three optical trapping patterns. For diffusing colloidal spheres this system is an optical thermal ratchet, and the ratchet-driven transport displays flux reversal as a function of the cycle frequency and the inter-trap separation. This is the first experimental observation of flux reversal in a symmetric thermal ratchet. Active potential energy landscapes are implemented with optical vortices, created from helical modes of light, that exert torques as well as forces. We demonstrate that arrays of optical vortices can organize colloidal spheres into microoptomechanical pumps, assembled by optical gradient forces and actuated by photon orbital angular momentum. Concentric circulating rings of particles formed by coaxial optical vortices form a microscopic Couette cell, in which hydrodynamic drag experienced by the spheres depends on the relative sense of the rings' circulation. Tracking the particles' motions we measure hydrodynamic coupling between the circular particle trains.

  7. A software tool for creating simulated outbreaks to benchmark surveillance systems

    Directory of Open Access Journals (Sweden)

    Olson Karen L


    Full Text Available Abstract Background Evaluating surveillance systems for the early detection of bioterrorism is particularly challenging when systems are designed to detect events for which there are few or no historical examples. One approach to benchmarking outbreak detection performance is to create semi-synthetic datasets containing authentic baseline patient data (noise and injected artificial patient clusters, as signal. Methods We describe a software tool, the AEGIS Cluster Creation Tool (AEGIS-CCT, that enables users to create simulated clusters with controlled feature sets, varying the desired cluster radius, density, distance, relative location from a reference point, and temporal epidemiological growth pattern. AEGIS-CCT does not require the use of an external geographical information system program for cluster creation. The cluster creation tool is an open source program, implemented in Java and is freely available under the Lesser GNU Public License at its Sourceforge website. Cluster data are written to files or can be appended to existing files so that the resulting file will include both existing baseline and artificially added cases. Multiple cluster file creation is an automated process in which multiple cluster files are created by varying a single parameter within a user-specified range. To evaluate the output of this software tool, sets of test clusters were created and graphically rendered. Results Based on user-specified parameters describing the location, properties, and temporal pattern of simulated clusters, AEGIS-CCT created clusters accurately and uniformly. Conclusion AEGIS-CCT enables the ready creation of datasets for benchmarking outbreak detection systems. It may be useful for automating the testing and validation of spatial and temporal cluster detection algorithms.

  12. Long-term dynamics and characteristics of snags created for wildlife habitat (United States)

    Barry, Amy M.; Hagar, Joan; Rivers, James W.


    Snags provide essential habitat for numerous organisms and are therefore critical to the long-term maintenance of forest biodiversity. Resource managers often use snag creation to mitigate the purposeful removal of snags at the time of harvest, but information regarding how created snags change over long timescales (>20 y) is absent from the literature. In this study, we evaluated the extent to which characteristics of large (>30 cm diameter at breast height [DBH]) Douglas-fir (Pseudotsuga menziesii) snags created by topping had changed after 25–27 y. We also tested whether different harvest treatments and snag configurations influenced present-day snag characteristics. Of 690 snags created in 1989–1991, 91% remained standing during contemporary surveys and 65% remained unbroken along the bole. Although most snags were standing, we detected increased bark loss and breaking along the bole relative to prior surveys conducted on the same pool of snags. Although snag characteristics were not strongly influenced by snag configuration, we found that snags in one harvest treatment (group selection) experienced less bark loss and had lower evidence of use by cavity-nesting birds (as measured by total cavity cover) relative to snags created with clearcut and two-story harvest treatments. Our results indicate that Douglas-fir snags created by topping can remain standing for long time-periods (≥25 y) in managed forests, and that the influence of harvest treatment on decay patterns and subsequent use by wildlife is an important consideration when intentionally creating snags for wildlife habitat.

  3. Pattern Formation in Materials (United States)

    Karma, Alain


    Pattern formation is ubiquitous in nature, from sand ripples formed by wind to the development of a complex biological organism with different organs and a central nervous system. In the realm of materials, patterns are formed invariably when matter is transformed between different solid, liquid or gaseous states far from thermodynamic equilibrium. Material failure is itself mediated by the propagation of cracks that form intricate patterns. Understanding how patterns form and evolve is key to design materials with desired properties and to optimize their performance and safety. This talk will discuss recent progress made to understand three distinct class of patterns including the highly branched snow-flake-like dendritic patterns formed during the solidification process, polycrystalline patterns shaped by grain boundaries, and crack patterns.

  4. Formalising Interaction Patterns (United States)

    Bottoni, Paolo; Guerra, Esther; de Lara, Juan

    The use of patterns as a way to refer to common solutions in the field of interface design is becoming widespread. However, contrary to the situation for software patterns, definitions of interaction patterns do not enjoy a common standard yet. Moreover, patterns are developed for design aspects as diverse as: user experience, layout, action coordination, or specification of entire widgets, reflecting the complexity of the field. As a consequence, research on formalisation of interaction patterns is not developed, and few attempts have been made to extend techniques developed for design pattern formalisation. We show here how an extension to an approach to pattern formalisation recently proposed by the authors can be usefully employed to formalize some classes of interaction patterns, to express relations like subtyping and composition, and to detect conflicts.

  5. Some remarks concerning the indicators for appreciation the performance and the value created by the enterprise

    Directory of Open Access Journals (Sweden)

    Doina Pacurari


    Full Text Available The appreciation of the performances of the enterprise are made, as a rule, by ways of indicators which are of accounting type, the result of financial exercise, profit or loss, being mostly used. This result can be determined differently, according to approaches of patrimonial, economic or financial nature. Due to the handling potential of this indicator, the attention of the analysts focused in time also on other computing patterns, uninfluenced by the accounting methods and techniques used by the enterprise. The investors’ need of information determined the conception of some performance computing models based on the concept of creating value for the shareholders. Among these, those which express the ability of the enterprise to create value on long term, based on discounted cash flow, are the most appreciated. Nevertheless, within the Romanian economic context, the most used performance indicators are still of accounting nature for being accessible and understandable.

  6. Afrikaans Syllabification Patterns

    Directory of Open Access Journals (Sweden)

    Tilla Fick


    Full Text Available In contrast to English, automatic hyphenation by computer of Afrikaans words is a problem that still needs to be addressed, since errors are still often encountered in printed text. An initial step in this task is the ability to automatically syllabify words. Since new words are created continuously by joining words, it is necessary to develop an “intelligent” technique for syllabification. As a first phase of the research, we consider only the orthographic information of words, and disregard both syntactic and morphological information. This approach allows us to use machine-learning techniques such as artificial neural networks and decision trees that are known for their pattern recognition abilities. Both these techniques are trained with isolated patterns consisting of input patterns and corresponding outputs (or targets that indicate whether the input pattern should be split at a certain position, or not. In the process of compiling a list of syllabified words from which to generate training data for the  syllabification problem, irregular patterns were identified. The same letter patterns are split differently in different words and complete words that are spelled identically are split differently due to meaning. We also identified irregularities in and between  the different dictionaries that we used. We examined the influence range of letters that are involved in irregularities. For example, for their in agter-ente and vaste-rente we have to consider three letters to the left of r to be certain where the hyphen should be inserted. The influence range of the k in verstek-waarde and kleinste-kwadrate is four to the left and three to the right. In an analysis of letter patterns in Afrikaans words we found that the letter e has the highest frequency overall (16,2% of all letters in the word list. The frequency of words starting with s is the highest, while the frequency of words ending with e is the highest. It is important to

  7. Hybrid strategies for nanolithography and chemical patterning (United States)

    Srinivasan, Charan

    Remarkable technological advances in photolithography have extended patterning to the sub-50-nm regime. However, because photolithography is a top-down approach, it faces substantial technological and economic challenges in maintaining the downward scaling trends of feature sizes below 30 nm. Concurrently, fundamental research on chemical self-assembly has enabled the path to access molecular length scales. The key to the success of photolithography is its inherent economies of scale, which justify the large capital investment for its implementation. In this thesis research, top-down and bottom-up approaches have been combined synergistically, and these hybrid strategies have been employed in applications that do not have the economies of scale found in semiconductor chip manufacturing. The specific instances of techniques developed here include molecular-ruler lithography and a series of nanoscale chemical patterning methods. Molecular-ruler lithography utilizes self-assembled multilayered films as a sidewall spacer on initial photolithographically patterned gold features (parent) to place a second-generation feature (daughter) in precise proximity to the parent. The parent-daughter separation, which is on the nanometer length scale, is defined by the thickness of the molecular-ruler resist. Analogous to protocols followed in industry to evaluate lithographic performance, electrical test-pad structures were designed to interrogate the nanostructures patterned by molecular-ruler nanolithography, failure modes creating electrical shorts were mapped to each lithographic step, and subsequent lithographic optimization was performed to pattern nanoscale devices with excellent electrical performance. The optimized lithographic processes were applied to generate nanoscale devices such as nanowires and thin-film transistors (TFTs). Metallic nanowires were patterned by depositing a tertiary generation material in the nanogap and surrounding micron-scale regions, and then

  14. Does AFTA Create More Trade for Thailand? An Investigation of Some Key Trade Indicators

    Directory of Open Access Journals (Sweden)

    Piriya Pholphirul


    Full Text Available This paper examines whether the ASEAN Free Trade Agreement (AFTA creates trade for Thailand or actually diverts it away from the country. It does this by analyzing various trade indicators: the Export Similarity Index, the Intra-Industry Trade Index, and Revealed Comparative Advantage (RCA rank correlation. By examining the patterns of trade between Thailand and other members of ASEAN, it reveals a high degree of similarity regarding the trade structure between Thailand and AFTA, which indicates that there will be fewer trade-creation benefits from AFTA and a greater likelihood of trade diversion once the AFTA scheme has been fully implemented. This similarity pattern explains the reasons for future collaboration among member countries and supportive arguments for the future extension of ASEAN ("ASEAN+". Market-penetration and development strategies should be employed by Thai exporters when accessing the ASEAN market.

  17. How a Balinese Traditional Home Creates a Comfortable Internal Environment without Resorting to Energy Usage

    Directory of Open Access Journals (Sweden)

    I Gst. Ngr. Anom Rajendra


    Full Text Available Abstract Balinese traditional home is one of traditional architectures in Indonesia in which it still survives up to now. The home as a part of Balinese Traditional Architecture derives from Balinese Hindu belief and their custom which have a lot of Hindu philosophy. Base on this philosophy, the house which is created as a model of human being and a model divine of macro cosmos. The aim of this is to create harmony between micro cosmos (human being and macro cosmos (nature. Physically, the usage of body measurements in the whole building dimensions has approved of how the implementation of a model of human being is created. Another thing is of how to abstractly create the building to have a soul through using basic dimension, mantra, and ritual for permission to the holy and devil spirit. Because of this, the building becomes a really unique thing.However, an interesting question reveals in relation to green building i.e. how does a Balinese traditional home create a comfortable internal environment without resorting energy usage? The presented paper has addressed it which is approached from the building layout to the building components. From those, the home appears that it has fully accounted to respond a warm-humid zone of the tropical climate. And a comfortable internal environment can be reached maximally through the use of open air concept or courtyard pattern in the building composition, most open and small buildings, the use of non bearing wall and also the critical point is the use of natural materials with low heat storage and large air cavity. Therefore, this means that the Balinese home has performed itself as a green building.

  9. DES Science Portal: II- Creating Science-Ready Catalogs

    Energy Technology Data Exchange (ETDEWEB)

    Fausti Neto, Angelo; et al.


    We present a novel approach for creating science-ready catalogs through a software infrastructure developed for the Dark Energy Survey (DES). We integrate the data products released by the DES Data Management and additional products created by the DES collaboration in an environment known as DES Science Portal. Each step involved in the creation of a science-ready catalog is recorded in a relational database and can be recovered at any time. We describe how the DES Science Portal automates the creation and characterization of lightweight catalogs for DES Year 1 Annual Release, and show its flexibility in creating multiple catalogs with different inputs and configurations. Finally, we discuss the advantages of this infrastructure for large surveys such as DES and the Large Synoptic Survey Telescope. The capability of creating science-ready catalogs efficiently and with full control of the inputs and configurations used is an important asset for supporting science analysis using data from large astronomical surveys.

    There has been no data on population based dietary patterns during the Ramadan fasting month. The purpose of this study was to detect Ramadan major dietary patterns among those who fast in Tehran. This cross-sectional study included 600 subjects, aged 18-65 with body mass index (BMI) of 18.5-40, who had decided to fast during Ramadan. Anthropometric measurements, usual physical activity level and educational status were collected two weeks before Ramadan. Information on Ramadan dietary intakes was obtained using a food frequency questionnaire and factor analysis was used to identify major dietary patterns. We identified four major dietary patterns: 1) Western-like pattern; high in fast foods, salty snacks, nuts, potato, fish, poultry, chocolates, juices; 2) high cholesterol and high sweet junk food pattern; high in pickles, sweets and condiments, butter and cream, canned fish, visceral meats and eggs; 3) Mediterranean-like pattern; high in vegetables, olive oil, dates, dairy, dried fruits, fruits, red meats, tea and coffee and 4) Ramadan-style pattern; large consumption of Halim, soups, porridges, legumes and whole grains, soft drinks, Zoolbia and Bamieh. Age was positively and inversely associated with Mediterranean-like (P = 0.003; r = 0.17) and Ramadan style (P = 0.1; r = -0.13) dietary pattern, respectively. Pre-Ramadan physical activity level was associated with a Mediterranean-like dietary pattern (P Ramadan-specific dietary pattern has unique characteristics, which has not yet been identified as a model of dietary pattern. Also, among identified dietary patterns, Mediterranean-like was the healthiest.

  6. Patterns of peer tutoring in nursing. (United States)

    Blowers, Sally; Ramsey, Priscilla; Merriman, Carolyn; Grooms, Janelle


    Peer tutoring in higher education is an effective strategy for promoting academic gains. Within nursing, peer tutoring has been used in the clinical setting, but little information is available regarding its use across the nursing curriculum. A peer tutoring program was created at a regional Appalachian university to meet the needs of students with poor academic backgrounds and multiple risk factors for failure. As the program naturally evolved, students moved beyond the time-honored one-on-one model. Many tutoring patterns developed including dyad, small group, large group, skill based, assignment based, and question based. Qualitative evaluation data from the program revealed that each pattern required different tutor skills, involved varied tutor-tutoree relationships, focused on different outcomes, and had certain advantages and disadvantages. All tutoring patterns contributed to improved academic skills and performance.

  7. Patterns and Interfaces in Dissipative Dynamics

    CERN Document Server

    Pismen, L.M


    Spontaneous pattern formation in nonlinear dissipative systems far from equilibrium is a paradigmatic case of emergent behaviour associated with complex systems. It is encountered in a great variety of settings, both in nature and technology, and has numerous applications ranging from nonlinear optics through solid and fluid mechanics, physical chemistry and chemical engineering to biology. Nature creates its variety of forms through spontaneous pattern formation and self-assembly, and this strategy is likely to be imitated by future biomorphic technologies. This book is a first-hand account by one of the leading players in this field, which gives in-depth descriptions of analytical methods elucidating the complex evolution of nonlinear dissipative systems, and brings the reader to the forefront of current research. The introductory chapter on the theory of dynamical systems is written with a view to applications of its powerful methods to spatial and spatio-temporal patterns. It is followed by two chapters t...

DNA strands from Bosenbergia rotunda were used as the fundamental element in patterning DNA on thin films of aluminium (Al metal without the need for any lithographic techniques. The DNA strands were applied in buffer solutions onto thin films of Al on silicon (Si and the chemical interactions between the DNA strands and Al creates nanometer scale arbitrary patterning by direct transfer of the DNA strands onto the substrate. This simple and cost-effective method can be utilized in the fabrication of various components in electronic chips for microelectronics and Nano Electronic Mechanical System (NEMS applications in general.

  9. Thermodynamics of complexity and pattern manipulation (United States)

    Garner, Andrew J. P.; Thompson, Jayne; Vedral, Vlatko; Gu, Mile


    Many organisms capitalize on their ability to predict the environment to maximize available free energy and reinvest this energy to create new complex structures. This functionality relies on the manipulation of patterns—temporally ordered sequences of data. Here, we propose a framework to describe pattern manipulators—devices that convert thermodynamic work to patterns or vice versa—and use them to build a "pattern engine" that facilitates a thermodynamic cycle of pattern creation and consumption. We show that the least heat dissipation is achieved by the provably simplest devices, the ones that exhibit desired operational behavior while maintaining the least internal memory. We derive the ultimate limits of this heat dissipation and show that it is generally nonzero and connected with the pattern's intrinsic crypticity—a complexity theoretic quantity that captures the puzzling difference between the amount of information the pattern's past behavior reveals about its future and the amount one needs to communicate about this past to optimally predict the future.

  12. An examination of the spatial distribution of the tissue fragments created during a single explosive attack. (United States)

    DuBois, E; Bowers, K; Rando, C


    Throughout the course of a forensic investigation following an explosive attack, the identification and recovery of tissue fragments is of extreme importance. There are few universally accepted methods to achieve this end. This project aims to explore this issue through the examination of the spatial distribution of the tissue fragments resulting from an explosive event. To address this, a two stage pilot study was conducted: first, a series of controlled explosions on porcine carcases was undertaken. Second, the data produced from these explosions were used to chart the spatial distribution of the tissue debris. In the controlled explosions, 3kg military grade explosive was chosen to create the maximum amount of fragmentation; this level of explosive also prevented the complete disappearance of forensic evidence through evaporation. Additionally, the blast created by military grade explosive is highly powerful and would mean that the maximum possible distance was achieved and would therefore allow the recorded distances and pattern spread to be a guideline for forensic recovery of associated with an explosive amount of an unknown size and quality. A total station was employed to record the location of the resulting forensic evidence, with the collected data analysed using R Studio. The observed patterns suggested that the distribution of remains is fairly consistent in trials under similar environmental conditions. This indicates potential for some general guidelines for forensic evidence collection (for example, the distance from the explosion that a search should cover). Copyright © 2017 The Authors.

  13. Creating context for critical thinking in practice: the role of the preceptor. (United States)

    Forneris, Susan Gross; Peden-McAlpine, Cynthia


    This paper is a report of a study to determine the impact of the preceptor coaching component of a reflective contextual learning intervention on novice nurses' critical thinking skills during the first 6 months of their practice. The use of preceptors to develop novice nurses' clinical skills has been well documented in the literature. However, there is little literature focused on preceptor involvement to develop novice nurses' critical thinking. This small case study was conducted in the United States of America in 2004 with six nurse/preceptor dyads. Stake's qualitative instrumental case study design was used to evaluate the preceptor component of the contextual learning intervention. Stories of preceptor experiences were analyzed using Stake's phases of data analysis (i.e. description, categorical aggregation, establishing patterns, naturalistic generalizations). Specific questions (e.g. nature of coaching used by the preceptor) guided the analysis. Repeating patterns were coded and isolated and later collapsed as the analysis moved forward. Preceptors use of the contextual learning intervention created a context that stimulated novice nurses' critical thinking. Two main themes describe the novice nurses' critical thinking skills relative to the preceptor coaching: 1) critical thinking as organizing and carrying out tasks; and 2) critical thinking as intentional, reflective thinking. Preceptor education should incorporate the following components: understanding the impact of power and anxiety on critical thinking of novice nurses transitioning into practice; creating dialogue that invites questions in a reflective and critical manner; and challenging thinking through sharing of perspectives.

  14. The Application of Data Mining Techniques to Create Promotion Strategy for Mobile Phone Shop (United States)

    Khasanah, A. U.; Wibowo, K. S.; Dewantoro, H. F.


    The number of mobile shop is growing very fast in various regions in Indonesia including in Yogyakarta due to the increasing demand of mobile phone. This fact leads high competition among the mobile phone shops. In these conditions the mobile phone shop should have a good promotion strategy in order to survive in competition, especially for a small mobile phone shop. To create attractive promotion strategy, the companies/shops should know their customer segmentation and the buying pattern of their target market. These kind of analysis can be done using Data mining technique. This study aims to segment customer using Agglomerative Hierarchical Clustering and know customer buying pattern using Association Rule Mining. This result conducted in a mobile shop in Sleman Yogyakarta. The clustering result shows that the biggest customer segment of the shop was male university student who come on weekend and from association rule mining, it can be concluded that tempered glass and smart phone “x” as well as action camera and waterproof monopod and power bank have strong relationship. This results that used to create promotion strategies which are presented in the end of the study.

  15. Creating a Virtual Learning Community with HUB Architecture: CLEERhub as a Case Study of User Adoption

    Directory of Open Access Journals (Sweden)

    Patrick L. Vogt


    Full Text Available The research aim of this article is to investigate the adoption patterns of HUB platforms that create and support virtual learning communities (VLC. The adoption patterns of one particular HUB called the Collaboratory for Engineering Education Research or CLEERhub, is presented as an example of how HUBs may be used as VLCs. After explaining the affordances of the HUB architecture, the article uses two approaches to discuss the adoption of CLEERhub by users. First, the authors link the five stages of Rogers’ Diffusion of Innovation model with various CLEERhub user metrics. The resultant mapping suggests that CLEERhub users are primarily in early stages of adoption. This is not an unexpected finding given that CLEERhub has been recently created. The second approach to studying adoption investigates the experience of a group of college students who used CLEERhub to aid them in completing a group assignment. A CLEERhub Usage Survey was developed and implemented during the last part of the semester to collect information about students’ experience with CLEERhub. Student reactions to CLEERhub were generally positive. After the two approaches are presented, the paper connects the approaches by speculating on how student experience (adoption approach 2 might be mapped to the five stages of Rogers’ model (adoption approach 1. The paper ends with considerations and suggestions for best practices.

  17. Combinatorial dispensing as a fast and efficient means to create complex screens. (United States)

    Hazes, Bart


    Liquid handling robots carry out tasks from simple plate filling to complex operations such as creating reagent cocktails from multiple stock solutions. The latter task is conceptually a combinatorial process where each cocktail is created by combining a subset of stock solutions in user-defined volumes. General-purpose liquid handlers can perform this task, but their hardware lacks the inherent properties needed to exploit the combinatorial nature of the problem at hand. Here we present the use of non-contact dispensing technologies to create complex screens at low volume and high density. Our approach is based on the "inkjet printer principle" where a block of dispensers (print head) travels over a multi-well plate (paper) to deliver the reagents (inks) in a user-defined pattern. Impact-induced mixing and the lack of tip contamination remove the need for extensive tip washing or the use of large numbers of disposable tips. As an example, protein crystallization screening is used to demonstrate the technology. This application requires the creation of complex mixtures from many stock solutions with a great diversity of viscosities and surface tensions. In addition, dispense volumes cover a range from 50 nL to 50 microL, illustrating its utility in low-volume high-density screening.

  18. The global coherence initiative: creating a coherent planetary standing wave. (United States)

    McCraty, Rollin; Deyhle, Annette; Childre, Doc


    via biological, electromagnetic, and nonlocal fields, it stands to reason that humans can work together in a co-creative relationship to consciously increase the coherence in the global field environment, which in turn distributes this information to all living systems within the field. GCI was established to help facilitate the shift in global consciousness from instability and discord to balance, cooperation, and enduring peace. A primary goal of GCI is to test the hypothesis that large numbers of people when in a heart-coherent state and holding a shared intention can encode information on the earth's energetic and geomagnetic fields, which act as carrier waves of this physiologically patterned and relevant information. In order to conduct this research, a global network of 12 to 14 ultrasensitive magnetic field detectors specifically designed to measure the earth's magnetic resonances is being installed strategically around the planet. More important is GCI's primary goal to motivate as many people as possible to work together in a more coherent and collaborative manner to increase the collective human consciousness. If we are persuaded that not only external fields of solar and cosmic origins but also human attention and emotion can directly affect the physical world and the mental and emotional states of others (consciousness), it broadens our view of what interconnectedness means and how it can be intentionally utilized to shape the future of the world we live in. It implies that our attitudes, emotions, and intentions matter and that coherent, cooperative intent can have positive effects. GCI hypothesizes that when enough individuals and social groups increase their coherence baseline and utilize that increased coherence to intentionally create a more coherent standing reference wave in the global field, it will help increase global consciousness. This can be achieved when an increasing number of people move towards more balanced and self-regulated emotions

  19. IBES: A Tool for Creating Instructions Based on Event Segmentation

    Directory of Open Access Journals (Sweden)

    Katharina eMura


    Full Text Available Receiving informative, well-structured, and well-designed instructions supports performance and memory in assembly tasks. We describe IBES, a tool with which users can quickly and easily create multimedia, step-by-step instructions by segmenting a video of a task into segments. In a validation study we demonstrate that the step-by-step structure of the visual instructions created by the tool corresponds to the natural event boundaries, which are assessed by event segmentation and are known to play an important role in memory processes. In one part of the study, twenty participants created instructions based on videos of two different scenarios by using the proposed tool. In the other part of the study, ten and twelve participants respectively segmented videos of the same scenarios yielding event boundaries for coarse and fine events. We found that the visual steps chosen by the participants for creating the instruction manual had corresponding events in the event segmentation. The number of instructional steps was a compromise between the number of fine and coarse events. Our interpretation of results is that the tool picks up on natural human event perception processes of segmenting an ongoing activity into events and enables the convenient transfer into meaningful multimedia instructions for assembly tasks. We discuss the practical application of IBES, for example, creating manuals for differing expertise levels, and give suggestions for research on user-oriented instructional design based on this tool.

  4. Patterning roadmap: 2017 prospects (United States)

    Neisser, Mark


    Road mapping of semiconductor chips has been underway for over 20 years, first with the International Technology Roadmap for Semiconductors (ITRS) roadmap and now with the International Roadmap for Devices and Systems (IRDS) roadmap. The original roadmap was mostly driven bottom up and was developed to ensure that the large numbers of semiconductor producers and suppliers had good information to base their research and development on. The current roadmap is generated more top-down, where the customers of semiconductor chips anticipate what will be needed in the future and the roadmap projects what will be needed to fulfill that demand. The More Moore section of the roadmap projects that advanced logic will drive higher-resolution patterning, rather than memory chips. Potential solutions for patterning future logic nodes can be derived as extensions of `next-generation' patterning technologies currently under development. Advanced patterning has made great progress, and two `next-generation' patterning technologies, EUV and nanoimprint lithography, have potential to be in production as early as 2018. The potential adoption of two different next-generation patterning technologies suggests that patterning technology is becoming more specialized. This is good for the industry in that it lowers overall costs, but may lead to slower progress in extending any one patterning technology in the future.

  6. Creating Value through Virtual Teams: A Current Literature Review

    Directory of Open Access Journals (Sweden)

    Akemi Takeoka Chatfield


    Full Text Available Globally, virtual teams (VT as ICT-enabled emergent network organisation forms have gained international validity by innovative organisations, with a corresponding surge of interest in understanding how organisations can leverage VT to create business value. Despite growing deliberations in VT literature on managing VT, tasks and outcomes, however, creating business value through VT remains an unresolved theoretical and pragmatic conundrum. A review of prior relevant literature is essential to advancing knowledge. The paucity of published review articles seems to have impeded the field’s accumulation of VT knowledge. This research, therefore, reviews the current literature on case studies of VT to address the question: What are organisational challenges in creating business value through VT in the organisation? The key challenges found in the literature are effective communication, knowledge sharing, trust, and interpersonal skills in the new virtual boundary-less environment. Drawing on the IT business value model, we also discuss their resource-based implications.

    Creating the Future with All Finance and Financial Conglomerates comprises an academic search for an understanding of all finance and financial conglomerates. It presents a strategic and economic analysis of diversification strategies and the growing interface between different types of financial firms. On the basis of a solid analysis of theoretical foundations and practical value, the book develops basic concepts of creating the future: especially solutions in managing risks and fresh ideas for the development of integrated financial services. The structure of the book is logical: starting on theoretical foundations (section 1, part A) and examining the economic value of All Finance and Financial Conglomerates (part B), leads to creating a concept for the future (part C). Case studies add additional practical value to this research. The review of the subject is completed by aspects of risk management in this sector and by political guidelines for the EU single market (section 2). The book builds further on ...

  8. Modelling biomechanics of bark patterning in grasstrees. (United States)

    Dale, Holly; Runions, Adam; Hobill, David; Prusinkiewicz, Przemyslaw


    Bark patterns are a visually important characteristic of trees, typically attributed to fractures occurring during secondary growth of the trunk and branches. An understanding of bark pattern formation has been hampered by insufficient information regarding the biomechanical properties of bark and the corresponding difficulties in faithfully modelling bark fractures using continuum mechanics. This study focuses on the genus Xanthorrhoea (grasstrees), which have an unusual bark-like structure composed of distinct leaf bases connected by sticky resin. Due to its discrete character, this structure is well suited for computational studies. A dynamic computational model of grasstree development was created. The model captures both the phyllotactic pattern of leaf bases during primary growth and the changes in the trunk's width during secondary growth. A biomechanical representation based on a system of masses connected by springs is used for the surface of the trunk, permitting the emergence of fractures during secondary growth to be simulated. The resulting fracture patterns were analysed statistically and compared with images of real trees. The model reproduces key features of grasstree bark patterns, including their variability, spanning elongated and reticulate forms. The patterns produced by the model have the same statistical character as those seen in real trees. The model was able to support the general hypothesis that the patterns observed in the grasstree bark-like layer may be explained in terms of mechanical fractures driven by secondary growth. Although the generality of the results is limited by the unusual structure of grasstree bark, it supports the hypothesis that bark pattern formation is primarily a biomechanical phenomenon.

    Array antennas are popular compared to discrete antennas as it is possible to control the radiation beams without much difficulty. Most of the investigations reported in literature contain the results on radiation patterns in which the sidelobe levels are relatively high, but these patterns of high sidelobe are not accepted for point to point communications and these high sidelobes create lot of hazards in low noise receivers. In view of these facts, an attempt is made to generate low sidelob...

  12. Creating Digital Elevation Model Using a Mobile Device (United States)

    Durmaz, A. İ.


    DEM (Digital Elevation Models) is the best way to interpret topography on the ground. In recent years, lidar technology allows to create more accurate elevation models. However, the problem is this technology is not common all over the world. Also if Lidar data are not provided by government agencies freely, people have to pay lots of money to reach these point clouds. In this article, we will discuss how we can create digital elevation model from less accurate mobile devices' GPS data. Moreover, we will evaluate these data on the same mobile device which we collected data to reduce cost of this modeling.

  1. Creating multithemed ecological regions for macroscale ecology: Testing a flexible, repeatable, and accessible clustering method (United States)

    Cheruvelil, Kendra Spence; Yuan, Shuai; Webster, Katherine E.; Tan, Pang-Ning; Lapierre, Jean-Francois; Collins, Sarah M.; Fergus, C. Emi; Scott, Caren E.; Norton Henry, Emily; Soranno, Patricia A.; Filstrup, Christopher T.; Wagner, Tyler


    Understanding broad-scale ecological patterns and processes often involves accounting for regional-scale heterogeneity. A common way to do so is to include ecological regions in sampling schemes and empirical models. However, most existing ecological regions were developed for specific purposes, using a limited set of geospatial features and irreproducible methods. Our study purpose was to: (1) describe a method that takes advantage of recent computational advances and increased availability of regional and global data sets to create customizable and reproducible ecological regions, (2) make this algorithm available for use and modification by others studying different ecosystems, variables of interest, study extents, and macroscale ecology research questions, and (3) demonstrate the power of this approach for the research question—How well do these regions capture regional-scale variation in lake water quality? To achieve our purpose we: (1) used a spatially constrained spectral clustering algorithm that balances geospatial homogeneity and region contiguity to create ecological regions using multiple terrestrial, climatic, and freshwater geospatial data for 17 northeastern U.S. states (~1,800,000 km2); (2) identified which of the 52 geospatial features were most influential in creating the resulting 100 regions; and (3) tested the ability of these ecological regions to capture regional variation in water nutrients and clarity for ~6,000 lakes. We found that: (1) a combination of terrestrial, climatic, and freshwater geospatial features influenced region creation, suggesting that the oft-ignored freshwater landscape provides novel information on landscape variability not captured by traditionally used climate and terrestrial metrics; and (2) the delineated regions captured macroscale heterogeneity in ecosystem properties not included in region delineation—approximately 40% of the variation in total phosphorus and water clarity among lakes was at the regional

  2. Nonlinear dynamics of pattern formation and pattern recognition in the rabbit olfactory bulb (United States)

    Baird, Bill


    A mathematical model of the process of pattern recognition in the first olfactory sensory cortex of the rabbit is presented. It explains the formation and alteration of spatial patterns in neural activity observed experimentally during classical Pavlovian conditioning. On each inspiration of the animal, a surge of receptor input enters the olfactory bulb. EEG activity recorded at the surface of the bulb undergoes a transition from a low amplitude background state of temporal disorder to coherent oscillation. There is a distinctive spatial pattern of rms amplitude in this oscillation which changes reliably to a second pattern during each successful recognition by the animal of a conditioned stimulus odor. When a new odor is paired as conditioned stimulus, these patterns are replaced by new patterns that stabilize as the animal adapts to the new environment. I will argue that a unification of the theories of pattern formation and associative memory is required to account for these observations. This is achieved in a model of the bulb as a discrete excitable medium with spatially inhomogeneous coupling expressed by a connection matrix. The theory of multiple Hopf bifurcations is employed to find coupled equations for the amplitudes of competing unstable oscillatory modes. These may be created in the system by proper coupling and selectively evoked by specific classes of inputs. This allows a view of limit cycle attractors as “stored” fixed points of a gradient vector field and thereby recovers the more familiar dynamical systems picture of associative memory.

  3. How Business Idea Fit Affects Sustainability and Creates Opportunities for Value Co-Creation in Nascent Firms

    Directory of Open Access Journals (Sweden)

    Gian Luca Casali


    Full Text Available A well-defined business idea is essential for nascent business sustainability in the future. The business idea must fit firm knowledge and resources to a profitable business opportunity. This work adopts the framework of value co-creation, strongly related to the service-dominant logic paradigm. We ask how does business idea fit affect new venture sustainability and create opportunities for value co-creation. We propose that a business idea that lacks fit is less sustainable, but it could create opportunities for value co-creation. This study develops and validates an empirically grounded taxonomy of business idea fit based on 729 Australian nascent firms using quantitative data generated from the results of a large study called CAUSEE (Comprehensive Australian Study of Entrepreneurial Emergence. A cluster analysis is used to identify distinct patterns of business idea fit. The empirical taxonomy developed in this study found four distinct clusters of firms, which were distinguished by the fit of their new business idea to knowledge, resources and market profitability: very good fit, low knowledge fit, low profit fit and low fit. Results show how these different patterns of fit create opportunities for value co-creation to create business future sustainability.

  10. Social enhancement can create adaptive, arbitrary and maladaptive cultural traditions (United States)

    Franz, Mathias; Matthews, Luke J.


    Many animals are known to learn socially, i.e. they are able to acquire new behaviours by using information from other individuals. Researchers distinguish between a number of different social-learning mechanisms such as imitation and social enhancement. Social enhancement is a simple form of social learning that is among the most widespread in animals. However, unlike imitation, it is debated whether social enhancement can create cultural traditions. Based on a recent study on capuchin monkeys, we developed an agent-based model to test the hypotheses that (i) social enhancement can create and maintain stable traditions and (ii) social enhancement can create cultural conformity. Our results supported both hypotheses. A key factor that led to the creation of cultural conformity and traditions was the repeated interaction of individual reinforcement and social enhancement learning. This result emphasizes that the emergence of cultural conformity does not necessarily require cognitively complex mechanisms such as ‘copying the majority’ or group norms. In addition, we observed that social enhancement can create learning dynamics similar to a ‘copy when uncertain’ learning strategy. Results from additional analyses also point to situations that should favour the evolution of learning mechanisms more sophisticated than social enhancement. PMID:20547762
