    We report the synthesis and characterization of C{sub 60} rate at SWCNT peapods and double-walled carbon nanotubes (DWCNTs) derived from the peapods. Single-walled carbon nanotubes (SWCNTs), C{sub 60} rate at SWCNT peapods, and DWCNTs were characterized by Raman and optical spectroscopy. The radial breathing modes (RBMs) of the tubes in C{sub 60} rate at SWCNT peapods are shifted to higher energies compared to the RBMs in SWCNTs, while in the case of DWCNTs the RBMs related to the outer tubes are shifted to lower energies compared to SWCNTs. A similar trend is observed for the absorption bands. These results suggest that the filling of the SWCNTs with C{sub 60} molecules decreases the average diameter of the electron cloud around the tubes, whereas the filling with an inner tube increases it.

    Strong permittivity fluctuation theory is used to solve the problem of scattering from a medium composed of completely randomly oriented scatterers under a low frequency limit. Gaussian statistics are not assumed for the renormalized scattering sources. Numerical results on effective permittivity are illustrated for oblate and prolate spheroidal scatterers and compared with the results for spherical scatterers. The results are consistent with discrete scatterer theory. The effective permittivity of a random medium embedded with nonspherical scatterers shows a higher imaginary part than the spherical scatterer case with equal correlation volume. Under the distorted Born approximation, the polarimetric covariance matrix for the backscattered electric field is calculated for half-space randomly oriented scatterers. The nonspherical geometry of the scatterers shows significant effects on the cross-polarized backscattering returns, and the correlation coefficient between HH and VV returns. The polarimetric backscattering coefficients can provide useful information in distinguishing the geometry of scatterers.

    Our aim in this study is to investigate the failure process in heterogeneous materials with randomly oriented fibers. In our proposed system, the fiber bundle model assumes that all the fibers are randomly oriented in all directions relative to the vertical one. Our calculations are performed in the framework of the local load-sharing rule, which states that the applied load of a broken fiber is redistributed only to its neighboring ones. The results show that this system presents a greater resistance than the classical one where the fibers are arranged parallel to the applied load. We found that the density of the broken fibers exhibited a power law and was linearly correlated with the applied load and temperature. However, the results show that the failure process of the considered system is characterized by an avalanche phenomenon with two different regimes. We also studied the crossover behavior of lifetime of the materials versus both applied load and temperature. We compared these results with those obtained from the classical model.

    The objective of this study was to compare the effect of virtual reality simulation training plus robotic orientation versus robotic orientation alone on performance of surgical tasks using an inanimate model. Surgical resident physicians were enrolled in this assessor-blinded randomized controlled trial. Residents were randomized to receive either (1) robotic virtual reality simulation training plus standard robotic orientation or (2) standard robotic orientation alone. Performance of surgical tasks was assessed at baseline and after the intervention. Nine of 33 modules from the da Vinci Skills Simulator were chosen. Experts in robotic surgery evaluated each resident's videotaped performance of the inanimate model using the Global Rating Scale (GRS) and Objective Structured Assessment of Technical Skills-modified for robotic-assisted surgery (rOSATS). Nine resident physicians were enrolled in the simulation group and 9 in the control group. As a whole, participants improved their total time, time to incision, and suture time from baseline to repeat testing on the inanimate model (P = 0.001, 0.003, virtual reality simulation improve surgical skills on an inanimate model, although this may be a function of the initial "practice" on the inanimate model and repeat testing of a known task. However, robotic virtual reality simulation training increases GRS pass rates consistent with improved robotic technical skills learned in a virtual reality environment.

    External magnetic fields have been used to vertically align ensembles of silicon microwires coated with ferromagnetic nickel films. X-ray diffraction and image analysis techniques were used to quantify the degree of vertical orientation of the microwires. The degree of vertical alignment and the minimum field strength required for alignment were evaluated as a function of the wire length, coating thickness, magnetic history, and substrate surface properties. Nearly 100% of 100 μm long, 2 μm diameter, Si microwires that had been coated with 300 nm of Ni could be vertically aligned by a 300 G magnetic field. For wires ranging from 40 to 60 μm in length, as the length of the wire increased, a higher degree of alignment was observed at lower field strengths, consistent with an increase in the available magnetic torque. Microwires that had been exposed to a magnetic sweep up to 300 G remained magnetized and, therefore, aligned more readily during subsequent magnetic field alignment sweeps. Alignment of the Ni-coated Si microwires occurred at lower field strengths on hydrophilic Si substrates than on hydrophobic Si substrates. The magnetic field alignment approach provides a pathway for the directed assembly of solution-grown semiconductor wires into vertical arrays, with potential applications in solar cells as well as in other electronic devices that utilize nano- and microscale components as active elements.

    Full Text Available Large ice hydrometeors are usually present in intense convective clouds and may significantly affect the upwelling radiances that are measured by satellite-borne microwave radiometers – especially, at millimeter-wavelength frequencies. Thus, interpretation of these measurements (e.g., for precipitation retrieval requires knowledge of the single scattering properties of ice particles. On the other hand, shape and internal structure of these particles (especially, the larger ones is very complex and variable, and therefore it is necessary to resort to simplifying assumptions in order to compute their single-scattering parameters.

    In this study, we use the discrete dipole approximation (DDA to compute the absorption and scattering efficiencies and the asymmetry factor of two kinds of quasi-spherical and non-homogeneous soft-ice particles in the frequency range 50–183 GHz. Particles of the first kind are modeled as quasi-spherical ice particles having randomly distributed spherical air inclusions. Particles of the second kind are modeled as random aggregates of ice spheres having random radii. In both cases, particle densities and dimensions are coherent with the snow hydrometeor category that is utilized by the University of Wisconsin – Non-hydrostatic Modeling System (UW-NMS cloud-mesoscale model. Then, we compare our single-scattering results for randomly-oriented soft-ice hydrometeors with corresponding ones that make use of: a effective-medium equivalent spheres, b solid-ice equivalent spheres, and c randomly-oriented aggregates of ice cylinders. Finally, we extend to our particles the scattering formulas that have been developed by other authors for randomly-oriented aggregates of ice cylinders.

    Full Text Available Antireflection with broadband and wide angle properties is important for a wide range of applications on photovoltaic cells and display. The SiOx shell layer provides a natural antireflection from air to the Si core absorption layer. In this work, we have demonstrated the random core-shell silicon nanowires with both broadband (from 400nm to 900nm and wide angle (from normal incidence to 60º antireflection characteristics within AM1.5 solar spectrum. The graded index structure from the randomly oriented core-shell (Air/SiOx/Si nanowires may provide a potential avenue to realize a broadband and wide angle antireflection layer.

    Aligned and randomly oriented chitosan nanofibers were prepared by electrospinning. The fibers were modified with the RGD cell-adhesive peptide through a heterobifunctional crosslinker containing a segment of poly(ethylene glycol) (PEG). PEG rendered the surface hydrophilic and provided flexible spacers, allowing the preservation of the bioactivity of further captured RGD peptides. NIH 3T3 cells were used to test the cellular compatibility of these chitosan nanofibrous scaffolds. Cell morphology and viability were investigated by SEM, fluorescent staining and cell counting. The results indicate that RGD-modified surfaces significantly improve the cellular compatibility of chitosan nanofibers and suggest a good candidate as a scaffold employed in tissue engineering.

    Child undervaccination is a complex public health problem and a contentious social and political issue. Efforts to increase vaccination coverage require understanding how the public evaluates different reasons for child undervaccination, which may influence attitudes, stigmatizing behaviors, and support for vaccination policies. We conducted a vignette experiment with a United States national online sample (n = 1469) to investigate how and why different undervaccination actions shape evaluations (blame, anger, sympathy, differentness, credibility, dangerousness), stigmatizing orientations (social distance, discrimination), and support for particular policies (e.g., research funding, belief exemptions, fines). Each participant was randomly assigned to read one of four vignettes that described a mother who either refused vaccines, delayed vaccines, encountered social barriers to obtaining vaccines, or was up-to-date on vaccines for her child. Compared to the up-to-date condition, each undervaccination action predicted significantly more negative evaluations and stigmatizing orientations. Vaccine refusal was the most negatively appraised. Differences in social distance and discrimination were explained by negative evaluations about the parent. These evaluations and orientations predicted support for a range of policies. Negative parental evaluations were associated with increased support for more severe policies. We discuss the implications of these findings for addressing undervaccination and informing health scholarship on stigma. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The carbon nanotube (CNT reinforced functionally graded materials (FGM are expected to be the new generation materials having wide range of unexplored potential applications in various technological areas such as aerospace and structural and chemical industry. The present work deals with the finite element modeling and free vibration analysis of CNT based functionally graded beam using three-dimensional Timoshenko beam theory. It has been assumed that the material properties of CNT based FG beam vary only along the thickness and these properties are evaluated by rule of mixture. The extended Hamilton principle has been applied to find out the governing equations of CNT based FG beam. Finite element method is used to solve governing equation with the exact shape functions. Initial analysis deals with CNTs assumed to be oriented along the length direction only. But practically it is not possible. So, further work deals with the free vibration analysis of functionally graded nanocomposite beams reinforced by randomly oriented straight single walled carbon nanotubes (SWCNTs. The Eshelby-Mori-Tanaka approach based on an equivalent fiber is used to investigate the material properties of the beam. Results are presented in tabular and graphical forms to show the effects of carbon nanotube orientations, slenderness ratios, and boundary conditions on the dynamic behavior of the beam.

    Schemes for X-ray imaging single protein molecules using new x-ray sources, like x-ray free electron lasers (XFELs), require processing many frames of data that are obtained by taking temporally short snapshots of identical molecules, each with a random and unknown orientation. Due to the small size of the molecules and short exposure times, average signal levels of much less than 1 photon/pixel/frame are expected, much too low to be processed using standard methods. One approach to process the data is to use statistical methods developed in the EMC algorithm (Loh & Elser, Phys. Rev. E, 2009) which processes the data set as a whole. In this paper we apply this method to a real-space tomographic reconstruction using sparse frames of data (below 10(-2) photons/pixel/frame) obtained by performing x-ray transmission measurements of a low-contrast, randomly-oriented object. This extends the work by Philipp et al. (Optics Express, 2012) to three dimensions and is one step closer to the single molecule reconstruction problem.

    Full Text Available Introduction: Neonatal intensive care unit induces the high level of anxiety for mothers. The aim of this study was to evaluate the effectiveness of NICU orientation program on the anxiety of mothers who had preterm newborns hospitalized in NICU. Methods: This study was a randomized clinical trial (three parallel groups. Participants included 99 mothers with preterm newborns hospitalized in NICU of Al- Zahra hospital, affiliated to Tabriz University of Medical Sciences in 2015. Mothers were randomly assigned to one of three groups (film, booklet, and control. Mothers completed the State- Trait Anxiety Inventory before entering to the NICU, and then mothers in the experiment groups became familiar with the NICU environment through watching a film or reading booklet. After the first NICU visit, all mothers completed the STAI and Cattell's Anxiety Questionnaires. Data were analyzed using SPSS ver. 13 software. Results: There was no significant difference between three groups regarding state- trait anxiety before the intervention. After the first NICU visit, a significant reduction in maternal state anxiety was seen in the both experiment groups. There was no statistical significant difference regarding trait anxiety. Data obtained from Cattell's anxiety questionnaire after intervention, showed significant difference in state anxiety between groups. Conclusion: Employing film and booklet orientation strategy after preterm delivery can reduce the mother’s anxiety and beneficent for the mother, baby, family and health care system.

    Fabricating scaffolds that can simulate the architecture and functionality of native extracellular matrix is a huge challenge in vascular tissue engineering. Various kinds of materials are engineered via nano-technological approaches to meet the current challenges in vascular tissue regeneration. During this study, nanofibers from pure polyurethane and hybrid polyurethane/collagen in two different morphologies (random and aligned) and in three different ratios of polyurethane:collagen (75:25; 50:50; 25:75) are fabricated by electrospinning. The fiber diameters of the nanofibrous scaffolds are in the range of 174-453 nm and 145-419 for random and aligned fibers, respectively, where they closely mimic the nanoscale dimensions of native extracellular matrix. The aligned polyurethane/collagen nanofibers expressed anisotropic wettability with mechanical properties which is suitable for regeneration of the artery. After 12 days of human aortic smooth muscle cells culture on different scaffolds, the proliferation of smooth muscle cells on hybrid polyurethane/collagen (3:1) nanofibers was 173% and 212% higher than on pure polyurethane scaffolds for random and aligned scaffolds, respectively. The results of cell morphology and protein staining showed that the aligned polyurethane/collagen (3:1) scaffold promote smooth muscle cells alignment through contact guidance, while the random polyurethane/collagen (3:1) also guided cell orientation most probably due to the inherent biochemical composition. Our studies demonstrate the potential of aligned and random polyurethane/collagen (3:1) as promising substrates for vascular tissue regeneration. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    We propose a method for deducing time-resolved structural changes in uncrystallized biomolecules in solution. The method relies on measuring the angular correlations of the intensities, when averaged over a large number of diffraction patterns from randomly oriented biomolecules in solution in a liquid solvent. The experiment is somewhat like a pump-probe version of an experiment on small angle X-ray scattering, except that the data expected by the algorithm are not just the radial variation of the averaged intensities. The differences of these correlation functions as measured from a photoexcited and dark structure enable the direct calculation of the difference electron density with a knowledge of only the dark structure. We exploit a linear relation we derive between the difference in these correlation functions and the difference electron density, applicable for small structural changes.

    Management of chronic mechanical neck pain (CMNP) still represents a challenge. A patient-oriented (Pa-O) therapeutic approach could be considered as the one in which therapies are scheduled at the start of each therapeutic session according to the patient's current physical status, and differs from a prescription-oriented (Pr-O) therapeutic approach, in which therapies are prescribed at the first medical referral and are not adjusted at any time during the treatment period. To determine if a Pa-O approach may be more beneficial for CMNP patients when compared to a Pr-O one. Randomized controlled trial. 220 CMNP outpatients randomized to either Pa-O group (N.=114) or Pr-O group (N.=106). Each group received 10 therapeutic sessions over 3 weeks. Primary outcome measures were pain assessment, evaluated by Visual-Analog-Scale (VAS), and disability level, evaluated by the Neck Pain and Disability Scale (NPDS-I). Secondary outcome measures included patients' response to treatment and treatment failures. Measurements were carried out at baseline (T0) and 1 month after treatment ended (T1). Data were analysed according to the intention-to-treat principle. Patients in both groups displayed at T1 a significant reduction in VAS and NPDS-I scores. The relative changes at T1 were greater in Pa-O group when compared with Pr-O group both for VAS (61.5% versus 48.8%; Pup in suffers from CMNP. However, the occurrence of a performance-bias due to the increased level of attention from physicians to patients in Pa-O group, cannot be ruled-out. A Pa-O approach should be considered for CMNP also in an outpatient facility.

    How organisms move and disperse is crucial to understand how population dynamics relates to the spatial heterogeneity of the environment. Random walk (RW) models are typical tools to describe movement patterns. Whether Lévy or alternative RW better describes forager movements is keenly debated. We get around this issue using the Generalized Pareto Distribution (GPD). GPD includes as specific cases Normal, exponential and power law distributions, which underlie Brownian, Poisson-like and Lévy walks respectively. Whereas previous studies typically confronted a limited set of candidate models, GPD lets the most likely RW model emerge from the data. We illustrate the wide applicability of the method using GPS-tracked seabird foraging movements and fishing vessel movements tracked by Vessel Monitoring System (VMS), both collected in the Peruvian pelagic ecosystem. The two parameters from the fitted GPD, a scale and a shape parameter, provide a synoptic characterization of the observed movement in terms of characteristic scale and diffusive property. They reveal and quantify the variability, among species and individuals, of the spatial strategies selected by predators foraging on a common prey field. The GPD parameters constitute relevant metrics for (1) providing a synthetic and pattern-oriented description of movement, (2) using top predators as ecosystem indicators and (3) studying the variability of spatial behaviour among species or among individuals with different personalities.

    Self-regulation theory and research suggests that different types of mental imagery can promote goal-directed behaviors. The present study was designed to compare the efficacy of approach imagery (attainment of desired goal states) and process imagery (steps for enacting behavior) in promoting physical activity among inactive individuals. A randomized controlled trial was conducted with 182 inactive adults who received one of four interventions for generating mental images related to physical activity over a 4-week period, with Approach Imagery (approach versus neutral) and Process Imagery (process versus no process) as the intervention strategies. Participants received imagery training and practiced daily. Repeated measures ANOVAs revealed that Approach Imagery: (1) increased approach motivations for physical activity at Week 4; (2) induced greater intentions post-session, which subsequently induced more action planning at Week 4; (3) enhanced action planning when combined with process images at post-session and Week 1; and (4) facilitated more physical activity at Week 4 via action planning. These findings suggest that inducing approach orientation via mental imagery may be a convenient and low-cost technique to promote physical activity among inactive individuals.

    Full Text Available Radiative properties of cirrus clouds are one of the major unsolved problems in climate studies and global radiation budget. These clouds are generally composed of various ice-crystal shapes, so we tried to evaluate effects of the ice-crystal shape on radiative fluxes. We calculated radiative fluxes of cirrus clouds with a constant geometrical depth, composed of ice crystals with different shapes (hexagonal columns, bullets, bullet-rosettes, sizes and various concentrations. We considered ice particles randomly oriented in space (3D case and their scattering phase functions were calculated by a ray-tracing method. We calculated radiative fluxes for cirrus layers for different microphysical characteristics by using a discrete-ordinate radiative code. Results showed that the foremost effect of the ice-crystal shape on radiative properties of cirrus clouds was that on the optical thickness, while the variation of the scattering phase function with the ice shape remained less than 3% for our computations. The ice-water content may be a better choice to parameterize the optical properties of cirrus, but the shape effect must be included.

  2. Processing of X-ray snapshots from crystals in random orientations.

    A functional expression is introduced that relates scattered X-ray intensities from a still or a rotation snapshot to the corresponding structure-factor amplitudes. The new approach was implemented in the program nXDS for processing monochromatic diffraction images recorded by a multi-segment detector where each exposure could come from a different crystal. For images containing indexable spots, the intensities of the expected reflections and their variances are obtained by profile fitting after mapping the contributing pixel contents to the Ewald sphere. The varying intensity decline owing to the angular distance of the reflection from the surface of the Ewald sphere is estimated using a Gaussian rocking curve. This decline is dubbed `Ewald offset correction', which is well defined even for still images. Together with an image-scaling factor and other corrections, an explicit expression is defined that predicts each recorded intensity from its corresponding structure-factor amplitude. All diffraction parameters, scaling and correction factors are improved by post-refinement. The ambiguous case of a lower point group than the lattice symmetry is resolved by a method reminiscent of the technique of `selective breeding'. It selects the indexing alternative for each image that yields, on average, the highest correlation with intensities from all other images. Processing a test set of rotation images by XDS and treating the same images by nXDS as snapshots of crystals in random orientations yields data of comparable quality, clearly indicating an anomalous signal from Se atoms.

    To investigate the treatment effects of bilateral robotic priming combined with the task-oriented approach on motor impairment, disability, daily function, and quality of life in patients with subacute stroke. A randomized controlled trial. Occupational therapy clinics in medical centers. Thirty-one subacute stroke patients were recruited. Participants were randomly assigned to receive bilateral priming combined with the task-oriented approach (i.e., primed group) or to the task-oriented approach alone (i.e., unprimed group) for 90 minutes/day, 5 days/week for 4 weeks. The primed group began with the bilateral priming technique by using a bimanual robot-aided device. Motor impairments were assessed by the Fugal-Meyer Assessment, grip strength, and the Box and Block Test. Disability and daily function were measured by the modified Rankin Scale, the Functional Independence Measure, and actigraphy. Quality of life was examined by the Stroke Impact Scale. The primed and unprimed groups improved significantly on most outcomes over time. The primed group demonstrated significantly better improvement on the Stroke Impact Scale strength subscale ( p = 0.012) and a trend for greater improvement on the modified Rankin Scale ( p = 0.065) than the unprimed group. Bilateral priming combined with the task-oriented approach elicited more improvements in self-reported strength and disability degrees than the task-oriented approach by itself. Further large-scale research with at least 31 participants in each intervention group is suggested to confirm the study findings.

    A local radial basis function meshless scheme (LRBFM) is developed to solve polarized radiative transfer in participating media containing randomly oriented axisymmetric particles in which radial basis functions augmented with polynomial basis are employed to construct the trial functions, and the vector radiative-transfer equation based on the discrete-ordinates approach is discretized directly by collocation method. The LRBFM belongs to a class of truly meshless methods that do not need any mesh or any numerical integration scheme. Performances of the LRBFM are verified with analytical solutions and other numerical results reported earlier in the literature via five various test cases. The predicted angular distribution of brightness temperature and Stokes vector by the LRBFM agree very well with the benchmark. It is demonstrated that the LRBFM is accurate to solve vector radiative transfer in participating media with randomly oriented axisymmetric particles.

    To examine the feasibility of a clinical trial on a novel, home-based task-oriented training with conventional hand exercises in people with rheumatoid arthritis or hand osteoarthritis. To explore the experiences of participants who completed their respective home exercise programmes. Thirty volunteer participants aged between 30 and 60 years and diagnosed with rheumatoid arthritis or hand osteoarthritis were proposed for a single-center, assessor-blinded, randomized controlled trial ( ClinicalTrials.gov : NCT01635582). Participants received task-oriented training with interactive computer games and objects of daily life or finger mobility and strengthening exercises. Both programmes were home based and were done four sessions per week with 20 minutes each session for 6 weeks. Major feasibility outcomes were number of volunteers screened, randomized, and retained; completion of blinded assessments, exercise training, and home exercise sessions; equipment and data management; and clinical outcomes of hand function. Reaching the recruitment target in 18 months and achieving exercise compliance >80% were set as success criteria. Concurrent with the trial, focus group interviews explored experiences of those participants who completed their respective programmes. After trial initiation, revisions in inclusion criteria were required to promote recruitment. A total of 17 participants were randomized and 15 were retained. Completion of assessments, exercise training, and home exercise sessions; equipment and data collection and management demonstrated excellent feasibility. Both groups improved in hand function outcomes and exercise compliance was above 85%. Participants perceived both programmes as appropriate and acceptable. Participants who completed task-oriented training also agreed that playing different computer games was enjoyable, engaging, and motivating. Findings demonstrate initial evidence on recruitment, feasibility of trial procedures, and acceptability of

    Full Text Available We present computational results on the shape dependency of the extinction and absorption cross sections of dustlike aerosol particles that were modeled as randomly oriented spheroids. Shape dependent variations in the extinction cross sections are largest in the size regime that is governed by the interference structure. Elongated spheroids best fitted measured extinction spectra of re-dispersed Saharan dust samples. For dust particles smaller than 1.5 μm in diameter and low absorption potential, shape effects on the absorption cross sections are very small.

    To compare from a societal perspective the cost-effectiveness and cost-utility of schema therapy, clarification-oriented psychotherapy, and treatment as usual for patients with avoidant, dependent, obsessive-compulsive, paranoid, histrionic, and/or narcissistic personality disorder. A multicenter, randomized controlled trial, single-blind parallel design, was conducted between May 2006 and December 2011 in 12 Dutch mental health institutes. Data from 320 patients (diagnosed according to DSM-IV criteria) randomly assigned to schema therapy (n = 145), treatment as usual (n = 134), or clarification-oriented psychotherapy (n = 41) were analyzed. Costs were repeatedly measured during 36 months by interview and patient registries. Primary outcome measures were proportion of recovered patients as measured with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders for the cost-effectiveness analysis, and quality-adjusted life-years (QALYs) for the cost-utility analysis. Bootstrap replications in the cost-effectiveness and the cost-utility planes were used to estimate the probability that one treatment was more cost-effective than the other. Mixed gamma regression on net monetary benefit for different levels of willingness to pay for extra effects was used as sensitivity analysis. Additional sensitivity analyses were done to assess robustness of the results. Due to higher clinical effects and lower costs, schema therapy was dominant over the other treatments in the cost-effectiveness analyses. Schema therapy has the probability of being the most cost-effective treatment (78% at €0 to 96% at €37,500 [$27,375] willingness to pay per extra recovery). Treatment as usual was more cost-effective than clarification-oriented psychotherapy due to lower costs. In the cost-utility analysis, schema therapy had a stable 75% probability of being cost-effective. Sensitivity analyses confirmed these findings. The results support the cost-effectiveness of schema

    A hybrid architecture consisting of an inverted organic photovoltaic device and a randomly-oriented electrospun PVDF piezoelectric device was fabricated as a highly-efficient energy generator. It uses the inverted photovoltaic device with coupled electrospun PVDF nanofibers as tandem structure to convert solar and mechanical vibrations energy to electricity simultaneously or individually. The power conversion efficiency of the photovoltaic device was also significantly improved up to 4.72% by optimized processes such as intrinsic ZnO, MoO3 and active layer. A simple electrospinning method with the two electrode technique was adopted to achieve a high voltage of - 300 mV in PVDF piezoelectric fibers. Highly-efficient HEG using voltage adder circuit provides the conceptual possibility of realizing multi-functional energy generator whenever and wherever various energy sources are available.

    The years spent in acquiring medical education is considered a stressful period in the life of many students. Students whose mental health deteriorates during this long period of study are less likely to become empathic and productive physicians. In addition to other specific stressors, academic examinations seem to further induce medical school-related stress and anxiety. Combined group and individual resource-oriented coaching early in medical education might reduce examination-related stress and anxiety and, consequently, enhance academic performance. Good quality evidence, however, remains scarce. In this study, therefore, we explored the question of whether coaching affects examination-related stress and health in medical students. We conducted a randomized controlled trial. Students who registered for the first medical academic examination in August 2014 at the University of Lübeck were recruited and randomized into three groups. The intervention groups 1 and 2 received a 1-hour psychoeducative seminar. Group 1 additionally received two 1-hour sessions of individual coaching during examination preparation. Group 3 served as a control group. We compared changes in self-rated general health (measured by a single item), anxiety and depression (measured by the hospital anxiety and depression scale), as well as medical school stress (measured by the perceived medical school stress instrument). In order to further investigate the influence of group allocation on perceived medical school stress, we conducted a linear regression analysis. We saw a significant deterioration of general health and an increase in anxiety and depression scores in medical students while preparing for an examination. We found a small, but statistically significant, effect of group allocation on the development of perceived medical school stress. However, we could not differentiate between the effects of group coaching only and group coaching in combination with two sessions of individual

    The high resolution satellite imagery (HRSI) have higher spatial resolution and less spectrum number, so there are some "object with different spectra, different objects with same spectrum" phenomena. The objective of this paper is to utilize the extracted features of high resolution satellite imagery (HRSI) obtained by the wavelet transform(WT) for segmentation. WT provides the spatial and spectral characteristics of a pixel along with its neighbors. The object-oriented Markov random Model in the wavelet domain is proposed in order to segment high resolution satellite imagery (HRSI). The proposed method is made up of three blocks: (1) WT-based feature extrcation.the aim of extraction of feature using WT for original spectral bands is to exploit the spatial and frequency information of the pixels; (2) over-segmentation object generation. Mean-Shift algorithm is employed to obtain over-segmentation objects; (3) classification based on Object-oriented Markov Random Model. Firstly the object adjacent graph (OAG) can be constructed on the over-segmentation objects. Secondly MRF model is easily defined on the OAG, in which WT-based feature of pixels are modeled in the feature field model and the neighbor system, potential cliques and energy functions of OAG are exploited in the labeling model. Experiments are conducted on one HRSI dataset-QuickBird images. We evaluate and compare the proposed approach with the well-known commercial software eCognition(object-based analysis approach) and Maximum Likelihood(ML) based pixels. Experimental results show that the proposed the method in this paper obviously outperforms the other methods.

    Full Text Available Xiaoqi He,1 Zizhao Zheng,1,2 Chao Hu1 1Ningbo Institute of Technology, Zhejiang University, Ningbo, People's Republic of China; 2Taiyuan University of Science and Technology, Taiyuan, People's Republic of China Abstract: The development of the capsule endoscope has made possible the examination of the whole gastrointestinal tract without much pain. However, there are still some important problems to be solved, among which, one important problem is the localization of the capsule. Currently, magnetic positioning technology is a suitable method for capsule localization, and this depends on a reliable system and algorithm. In this paper, based on the magnetic dipole model as well as magnetic sensor array, we propose nonlinear optimization algorithms using a random complex algorithm, applied to the optimization calculation for the nonlinear function of the dipole, to determine the three-dimensional position parameters and two-dimensional direction parameters. The stability and the antinoise ability of the algorithm is compared with the Levenberg–Marquart algorithm. The simulation and experiment results show that in terms of the error level of the initial guess of magnet location, the random complex algorithm is more accurate, more stable, and has a higher “denoise” capacity, with a larger range for initial guess values.

    The noninvasive cardiac output monitor and passive leg-raising maneuver has been shown to be reasonably accurate in predicting fluid responsiveness in critically ill patients. We examine whether using a noninvasive protocol would result in more rapid lactate clearance after 3 hours in patients with severe sepsis and septic shock in the emergency department. In this open-label randomized controlled trial, 122 adult patients with sepsis and serum lactate concentration of greater than or equal to 3.0 mmol/L were randomized to receive usual care or intravenous fluid bolus administration guided by measurements of change of stroke volume index, using the noninvasive cardiac output monitor after passive leg-raising maneuver. The primary outcome was lactate clearance of more than 20% at 3 hours. Secondary outcomes included mortality, length of hospital and ICU stay, and total hospital cost. Analysis was intention to treat. Similar proportions of patients in the randomized intervention group (70.5%; N=61) versus control group (73.8%; N=61) achieved the primary outcome, with a relative risk of 0.96 (95% confidence interval [CI] 0.77 to 1.19). Secondary outcomes were similar in both groups (P>.05 for all comparisons). Hospital mortality occurred in 6 patients (9.8%) each in the intervention and control groups on or before 28 days (relative risk=1.00; 95% CI 0.34 to 2.93). Among a subgroup of patients with underlying fluid overload states, those in the intervention group tended to receive clinically significantly more intravenous fluids at 3 hours (difference=975 mL; 95% CI -450 to 1,725 mL) and attained better lactate clearance (difference=19.7%; 95% CI -34.6% to 60.2%) compared with the control group, with shorter hospital lengths of stay (difference=-4.5 days; 95% CI -9.5 to 2.5 days). Protocol-based fluid resuscitation of patients with severe sepsis and septic shock with the noninvasive cardiac output monitor and passive leg-raising maneuver did not result in better

    Hwa-byung, a Korean culture-bound syndrome with both psychological and somatic symptoms, is also known as 'anger syndrome'. It includes various physical symptoms including anxiety, a feeling of overheating, a sensation of pressure on the chest, heart palpitations, respiratory stuffiness, insomnia, and anxiety. The proposed study is a single-center, double-blind, randomized, controlled trial with two parallel arms: an oriental medicine music therapy (OMMT) group and a control music therapy (CMT) group. In total, 48 patients will be enrolled into the trial. The first visit will be the screening visit. At baseline (visit 2), all participants fulfilling both the inclusion and the exclusion criteria will be split and randomly divided into two equal groups: the OMMT and the CMT (n = 24 each). Each group will receive treatment sessions over the course of 4 weeks, twice per week, for eight sessions in total. The primary outcome is the State-Trait Anxiety Inventory (STAI), and the secondary outcomes are the Hwa-byung scale (H-scale), the Center for Epidemiologic Studies Depression Scale (CES-D), the Hwa-byung visual analogue scale (H-VAS) for primary symptoms, the World Health Organization Quality of Life scale, brief version (WHOQOL-BREF), and levels of salivary cortisol. Patients will be asked to complete questionnaires at the baseline visit (visit 2), after the last treatment session (visit 9), and at 4 weeks after the end of all trial sessions (visit 10). From the baseline (visit 2) through the follow-up (visit 10), the entire process will take a total of 53 days. This proposed study targets patients with Hwa-byung, especially those who have exhibited symptoms of anxiety. Therefore, the primary outcome is set to measure the level of anxiety. OMMT is music therapy combined with traditional Korean medicinal theories. Unlike previously reported music therapies, for which patients simply listen to music passively, in OMMT, patients actively move their bodies and play the

    To compare the effectiveness of a core stability program with a task-oriented motor training program in improving motor proficiency in children with developmental coordination disorder (DCD). Randomized controlled pilot trial. Outpatient unit in a hospital. Twenty-two children diagnosed with DCD aged 6-9 years were randomly allocated to the core stability program or the task-oriented motor program. Both groups underwent their respective face-to-face training session once per week for eight consecutive weeks. They were also instructed to carry out home exercises on a daily basis during the intervention period. Short Form of the Bruininks-Oseretsky Test of Motor Proficiency (Second Edition) and Sensory Organization Test at pre- and post-intervention. Intention-to-treat analysis revealed no significant between-group difference in the change of motor proficiency standard score (P=0.717), and composite equilibrium score derived from the Sensory Organization Test (P=0.100). Further analysis showed significant improvement in motor proficiency in both the core stability (mean change (SD)=6.3(5.4); p=0.008) and task-oriented training groups (mean change(SD)=5.1(4.0); P=0.007). The composite equilibrium score was significantly increased in the task-oriented training group (mean change (SD)=6.0(5.5); P=0.009), but not in the core stability group (mean change(SD) =0.0(9.6); P=0.812). In the task-oriented training group, compliance with the home program was positively correlated with change in motor proficiency (ρ=0.680, P=0.030) and composite equilibrium score (ρ=0.638, P=0.047). The core stability exercise program is as effective as task-oriented training in improving motor proficiency among children with DCD. © The Author(s) 2014.

    The current study examined the frequency with which randomized controlled trials (RCTs) of behavioral and psychological interventions for anxiety and depression include data pertaining to participant sexual orientation and nonbinary gender identities. Using systematic review methodology, the databases PubMed and PsycINFO were searched to identify RCTs published in 2004, 2009, and 2014. Random selections of 400 articles per database per year (2,400 articles in total) were considered for inclusion in the review. Articles meeting inclusion criteria were read and coded by the research team to identify whether the trial reported data pertaining to participant sexual orientation and nonbinary gender identities. Additional trial characteristics were also identified and indexed in our database (e.g., sample size, funding source). Of the 232 articles meeting inclusion criteria, only 1 reported participants' sexual orientation, and zero articles included nonbinary gender identities. A total of 52,769 participants were represented in the trials, 93 of which were conducted in the United States, and 43 acknowledged the National Institutes of Health as a source of funding. Despite known mental health disparities on the basis of sexual orientation and nonbinary gender identification, researchers evaluating interventions for anxiety and depression are not reporting on these important demographic characteristics. Reporting practices must change to ensure that our interventions generalize to lesbian, gay, bisexual, and transgender persons. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Over fifty percent of stroke patients experience chronic arm hand performance problems, compromising independence in daily life activities and quality of life. Task-oriented training may improve arm hand performance after stroke, whereby augmented therapy may lead to a better treatment outcome. Technology-supported training holds opportunities for increasing training intensity. However, the effects of robot-supported task-oriented training with real life objects in stroke patients are not known to date. The aim of the present study was to investigate the effectiveness and added value of the Haptic Master robot combined with task-oriented arm hand training in chronic stroke patients. In a single-blind randomized controlled trial, 22 chronic stroke patients were randomly allocated to receive either task-oriented robot-assisted arm-hand training (experimental group) or task-oriented non-robotic arm-hand training (control group). For training, the T-TOAT (Technology-supported Task-Oriented Arm Training) method was applied. Training was provided during 8 weeks, 4 times/week, 2 × 30 min/day. A significant improvement after training on the Action Research Arm Test (ARAT) was demonstrated in the experimental group (p = 0.008). Results were maintained until 6 months after cessation of the training. On the perceived performance measure (Motor Activity Log (MAL)), both, the experimental and control group improved significantly after training (control group p = 0.008; experimental group p = 0.013). The improvements on MAL in both groups were maintained until 6 months after cessation of the training. With regard to quality of life, only in the control group a significant improvement after training was found (EuroQol-5D p = 0.015, SF-36 physical p = 0.01). However, the improvement on SF-36 in the control group was not maintained (p = 0.012). No between-group differences could be demonstrated on any of the outcome measures. Arm hand performance improved in chronic stroke

    Highlights: • Hydrothermally grown, randomly oriented, and low areal density ZnO nanorods have been successfully adopted as the electron transport layer in inverted organic solar cells. • The addition of atomic layer deposited ZnO on the ZnO nanorods effectively enhance the photovoltaic performances of inverted organic solar cells. • The inverted organic solar cells with 5 nm thick-ALD ZnO showed the highest power conversion efficiency of 3.08%, which is an enhancement of approximately 80% compared to the cells without the ALD ZnO layer (PCE = 1.67%). - Abstract: Nanostructuring of the electron transport layer (ETL) in organic photovoltaic cells (OPV) is of great interest because it increases the surface area of the cell and electron transport. In this work, hydrothermally grown, randomly oriented, and low areal density ZnO nanorods (NRs) have been adopted as the ETL, and the effect of adding atomic layer deposited (ALD) ZnO on the ZnO NRs on the inverted organic solar cell performance has been investigated. The fabricated inverted organic solar cell with 5-nm-thick ALD-ZnO grown on the ZnO NRs showed the highest power conversion efficiency (PCE) of 3.08%, which is an enhancement of 85% from that of the cell without ALD-ZnO (PCE = 1.67%). The ultrathin ALD-ZnO was found to act as a curing layer of the surface defects on the hydrothermally grown ZnO NRs, resulting in an improvement in photovoltaic performance.

    Full Text Available The method of angular correlations recovers quantities from diffraction patterns of randomly oriented particles, as expected to be measured with an X-ray free electron laser (XFEL, proportional to quadratic functions of the spherical harmonic expansion coefficients of the diffraction volume of a single particle. We have previously shown that it is possible to reconstruct a randomly oriented icosahedral or helical virus from the average over all measured diffraction patterns of such correlations. We point out in this paper that a structure of even simpler particles of 50 Å or so in diameter and consisting of heavier atomic elements (to enhance scattering that has been used as a test case for reconstructions from XFEL diffraction patterns can also be solved by this technique. Even though there has been earlier work on similar objects (prolate spheroids, one advantage of the present technique is its potential to also work with diffraction patterns not only due to single particles as has been suggested on the basis on nonoverlapping delta functions of angular scattering. Accordingly, we calculated from the diffraction patterns the angular momentum expansions of the pair correlations and triple correlations for general particle images and reconstructed those images in the standard way. Although the images looked pretty much the same, it is not totally clear to us that the angular correlations are exactly the same as different numbers of particles due to the possibility of constructive or destructive interference between the scattered waves from different particles. It is of course known that, for a large number of particles contributing to a diffraction parttern, the correlations converge to that of a single particle. It could be that the lack of perfect agreement between the images reconstructed with one and two particles is due to uncancelling constructive and destructive conditions that are not found in the case of solution scattering.

    The effects of a comprehensive shared decision-making system based on the CommonGround approach and incorporating peer support and a computerized decision aid were investigated. A pilot randomized controlled trial with six-month follow-up was conducted in Japan. Fifty-six outpatients with mental illness were randomly allocated to a shared decision-making system (intervention) group or treatment as usual (control) group. The implementation process and several outcomes were compared between groups. The core components and processes of shared decision making were observed in the intervention group more frequently than in the control group. The intervention group also reported a significantly more positive participants' view of the relationship with their doctor than the control group. The intervention did not have a significant effect on most clinical and recovery-related outcomes. The shared decision-making system appeared to partly improve patients' perceptions of communication and relationships with doctors but did not have a significant effect on other patient-level outcomes.

    Recovery features strongly in Australian mental health policy; however, evidence is limited for the efficacy of recovery-oriented practice at the service level. This paper describes the Principles Unite Local Services Assisting Recovery (PULSAR) Specialist Care trial protocol for a recovery-oriented practice training intervention delivered to specialist mental health services staff. The primary aim is to evaluate whether adult consumers accessing services where staff have received the intervention report superior recovery outcomes compared to adult consumers accessing services where staff have not yet received the intervention. A qualitative sub-study aims to examine staff and consumer views on implementing recovery-oriented practice. A process evaluation sub-study aims to articulate important explanatory variables affecting the interventions rollout and outcomes. The mixed methods design incorporates a two-step stepped-wedge cluster randomized controlled trial (cRCT) examining cross-sectional data from three phases, and nested qualitative and process evaluation sub-studies. Participating specialist mental health care services in Melbourne, Victoria are divided into 14 clusters with half randomly allocated to receive the staff training in year one and half in year two. Research participants are consumers aged 18-75 years who attended the cluster within a previous three-month period either at baseline, 12 (step 1) or 24 months (step 2). In the two nested sub-studies, participation extends to cluster staff. The primary outcome is the Questionnaire about the Process of Recovery collected from 756 consumers (252 each at baseline, step 1, step 2). Secondary and other outcomes measuring well-being, service satisfaction and health economic impact are collected from a subset of 252 consumers (63 at baseline; 126 at step 1; 63 at step 2) via interviews. Interview-based longitudinal data are also collected 12 months apart from 88 consumers with a psychotic disorder

    Background: Slackline-training has been shown to improve mainly task-specific balancing skills. Non-task specific effects were assessed for tandem stance and preferred one-leg stance on stable and perturbed force platforms with open eyes. It is unclear whether transfer effects exist for other balancing conditions and which component of the balancing ability is affected. Also, it is not known whether slackline-training can improve non-visual-dependent spatial orientation abilities, a function mainly supported by the hippocampus. Objective: To assess the effect of one-month of slackline-training on different components of balancing ability and its transfer effects on non-visual-dependent spatial orientation abilities. Materials and Methods: Fifty subjects aged 18-30 were randomly assigned to the training group (T) (n = 25, 23.2 ± 2.5 years; 12 females) and the control group (C) (n = 25, 24.4 ± 2.8 years; 11 females). Professional instructors taught the intervention group to slackline over four consecutive weeks with three 60-min-trainings in each week. Data acquisition was performed (within 2 days) by blinded investigators at the baseline and after the training. Main outcomes Improvement in the score of a 30-item clinical balance test (CBT) developed at our institute (max. score = 90 points) and in the average error distance (in centimeters) in an orientation test (OT), a triangle completion task with walking and wheelchair conditions for 60°, 90°, and 120°. Results: Training group performed significantly better on the closed-eyes conditions of the CBT (1.6 points, 95% CI: 0.6 to 2.6 points vs. 0.1 points, 95% CI: -1 to 1.1 points; p = 0.011, [Formula: see text] = 0.128) and in the wheelchair (vestibular) condition of the OT (21 cm, 95% CI: 8-34 cm vs. 1 cm, 95% CI: -14-16 cm; p = 0.049, [Formula: see text] = 0.013). Conclusion: Our results indicate that one month of intensive slackline training is a novel approach for enhancing clinically relevant balancing

    Cognitive Orientation to daily Occupational Performance (CO-OP) approach based on cognitive strategy in occupational therapy. To investigate the effects of CO-OP approach on occupational performance in individuals with hemiparetic stroke. This study was designed as a 5-week, randomized, single-blind. Forty-three participants who had a diagnosis of first stroke were enrolled in this study. The participants were randomly assigned to the experimental group (n = 20) or the control group (n = 23). The experimental group conducted CO-OP approach while the control group conducted conventional occupational therapy based on occupational performance components. This study measured Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS). Outcome measurements were performed at baseline and post-intervention. After training, the scores of COPM and PQRS in trained task were significantly higher for the score in the experimental group than the control group. In addition, the non-trained task was significantly higher for the score in the experimental group than the control group in COPM and the PQRS. This study suggests that the CO-OP approach is beneficial effects on the occupational performance to improvement in individuals with hemiparetic stroke, and have positive effects on generalization and transfer of acquired skills.

    Motive-oriented therapeutic relationship (MOTR, also called complementary therapeutic relationship) was postulated to be a particularly helpful therapeutic ingredient in the early-phase treatment of patients with personality disorders, in particular borderline personality disorder (BPD). The present pilot study of randomized controlled trial using an add-on design aims to investigate the effects of MOTR in early-phase treatment (up to session 10), with BPD patients on therapeutic alliance, session impact, and outcome. In total, N = 25 patients participated in the study. BPD patients were randomly allocated to a manual-based investigation process in 10 sessions or to the same investigation process infused with MOTR. Adherence ratings were performed and yielded satisfactory results. The results suggested a specific effectiveness of MOTR on the interpersonal problem area, on the quality of the therapeutic alliance and the quality of the therapeutic relationship, as rated by the patient. These results may have important clinical implications for the early-phase treatment of patients presenting with BPD.

    Motive-oriented therapeutic relationship (MOTR) was postulated to be a particularly helpful therapeutic ingredient in the early treatment phase of patients with personality disorders, in particular with borderline personality disorder (BPD). The present randomized controlled study using an add-on design is the first study to test this assumption in a 10-session general psychiatric treatment with patients presenting with BPD on symptom reduction and therapeutic alliance. A total of 85 patients were randomized. They were either allocated to a manual-based short variant of the general psychiatric management (GPM) treatment (in 10 sessions) or to the same treatment where MOTR was deliberately added to the treatment. Treatment attrition and integrity analyses yielded satisfactory results. The results of the intent-to-treat analyses suggested a global efficacy of MOTR, in the sense of an additional reduction of general problems, i.e. symptoms, interpersonal and social problems (F1, 73 = 7.25, p < 0.05). However, they also showed that MOTR did not yield an additional reduction of specific borderline symptoms. It was also shown that a stronger therapeutic alliance, as assessed by the therapist, developed in MOTR treatments compared to GPM (Z55 = 0.99, p < 0.04). These results suggest that adding MOTR to psychiatric and psychotherapeutic treatments of BPD is promising. Moreover, the findings shed additional light on the perspective of shortening treatments for patients presenting with BPD. © 2014 S. Karger AG, Basel.

    In many clinical settings, there is a high comorbidity between substance use disorders, psychiatric disorders, and traumatic stress. Novel therapies are needed to address these co-occurring issues efficiently. The aim of the present study was to conduct a pragmatic randomized controlled trial comparing Mindfulness-Oriented Recovery Enhancement (MORE) to group Cognitive-Behavioral Therapy (CBT) and treatment-as-usual (TAU) for previously homeless men residing in a therapeutic community. Men with co-occurring substance use and psychiatric disorders, as well as extensive trauma histories, were randomly assigned to 10 weeks of group treatment with MORE (n = 64), CBT (n = 64), or TAU (n = 52). Study findings indicated that from pre-to post-treatment MORE was associated with modest yet significantly greater improvements in substance craving, post-traumatic stress, and negative affect than CBT, and greater improvements in post-traumatic stress and positive affect than TAU. A significant indirect effect of MORE on decreasing craving and post-traumatic stress by increasing dispositional mindfulness was observed, suggesting that MORE may target these issues via enhancing mindful awareness in everyday life. This pragmatic trial represents the first head-to-head comparison of MORE against an empirically-supported treatment for co-occurring disorders. Results suggest that MORE, as an integrative therapy designed to bolster self-regulatory capacity, may hold promise as a treatment for intersecting clinical conditions. Copyright © 2015 Elsevier Ltd.

    This study examined the effect of a reflective interpersonal gratitude journal, a reflective-behavioral interpersonal gratitude journal and an active control journal, on primary qualities of well-being and depression. Participants (n = 192; 67.2% female) completed this 3-month longitudinal randomized controlled design. Participants in the reflective-behavioral condition experienced the greatest improvements in affect balance and reductions in depression at immediate posttest. Both gratitude interventions improved affect balance at 1 month, compared to the control. Changes in affect balance for those in the reflective-behavioral condition were mediated by the rate at which people expressed gratitude in their existing relationships. This effect was moderated by participant's baseline depressive status. Expressing felt gratitude to others appears to be a crucial step in deriving benefits, and these benefits may not be limited to the emotionally healthy. Given the applied popularity of gratitude interventions, understanding not only if but also how they work is essential. © 2017 Wiley Periodicals, Inc.

  17. Mobile Augmented Reality as a Feature for Self-Oriented, Blended Learning in Medicine: Randomized Controlled Trial

    Science.gov (United States)

    2017-01-01

    Background Advantages of mobile Augmented Reality (mAR) application-based learning versus textbook-based learning were already shown in a previous study. However, it was unclear whether the augmented reality (AR) component was responsible for the success of the self-developed app or whether this was attributable to the novelty of using mobile technology for learning. Objective The study’s aim was to test the hypothesis whether there is no difference in learning success between learners who employed the mobile AR component and those who learned without it to determine possible effects of mAR. Also, we were interested in potential emotional effects of using this technology. Methods Forty-four medical students (male: 25, female: 19, mean age: 22.25 years, standard deviation [SD]: 3.33 years) participated in this study. Baseline emotional status was evaluated using the Profile of Mood States (POMS) questionnaire. Dermatological knowledge was ascertained using a single choice (SC) test (10 questions). The students were randomly assigned to learn 45 min with either a mobile learning method with mAR (group A) or without AR (group B). Afterwards, both groups were again asked to complete the previous questionnaires. AttrakDiff 2 questionnaires were used to evaluate the perceived usability as well as pragmatic and hedonic qualities. For capturing longer term effects, after 14 days, all participants were again asked to complete the SC questionnaire. All evaluations were anonymous, and descriptive statistics were calculated. For hypothesis testing, an unpaired signed-rank test was applied. Results For the SC tests, there were only minor differences, with both groups gaining knowledge (average improvement group A: 3.59 [SD 1.48]; group B: 3.86 [SD 1.51]). Differences between both groups were statistically insignificant (exact Mann Whitney U, U=173.5; P=.10; r=.247).

    To study the effects of augmented exercise therapy time for arm rehabilitation as either Bobath therapy or the impairment-oriented training (Arm BASIS training) in stroke patients with arm severe paresis. Single blind, multicentre randomized control trial. Three inpatient neurorehabilitation centres. Sixty-two anterior circulation ischaemic stroke patients. Random assignment to three group: (A) no augmented exercise therapy time, (B) augmented exercise therapy time as Bobath therapy and (C) augmented exercise therapy time as Arm BASIS training. Fugl-Meyer arm motor score. Secondary measure: Action Research Arm Test (ARA). Ancillary measures: Fugl-Meyer arm sensation and joint motion/pain scores and the Ashworth Scale (elbow flexors). An overall effect of augmented exercise therapy time on Fugl-Meyer scores after four weeks was not corroborated (mean and 95% confidence interval (CI) of change scores: no augmented exercise therapy time (n=20) 8.8, 5.2-12.3; augmented exercise therapy time (n=40) 9.9, 6.8-13.9; p = 0.2657). The group who received the augmented exercise therapy time as Arm BASIS training (n=20) had, however, higher gains than the group receiving the augmented exercise therapy time as Bobath therapy (n=20) (mean and 95% CI of change scores: Bobath 7.2, 2.6-11.8; BASIS 12.6, 8.4-16.8; p = 0.0432). Passive joint motion/pain deteriorated less in the group who received BASIS training (mean and 95% CI of change scores: Bobath -3.2, -5.2 to -1.1; BASIS 0.1, -1.8-2.0; p = 0.0090). ARA, Fugl-Meyer arm sensation, and Ashworth Scale scores were not differentially affected. The augmented exercise therapy time as Arm BASIS training enhanced selective motor control. Type of training was more relevant for recovery of motor control than therapeutic time spent.

    Nanostructuring of the electron transport layer (ETL) in organic photovoltaic cells (OPV) is of great interest because it increases the surface area of the cell and electron transport. In this work, hydrothermally grown, randomly oriented, and low areal density ZnO nanorods (NRs) have been adopted as the ETL, and the effect of adding atomic layer deposited (ALD) ZnO on the ZnO NRs on the inverted organic solar cell performance has been investigated. The fabricated inverted organic solar cell with 5-nm-thick ALD-ZnO grown on the ZnO NRs showed the highest power conversion efficiency (PCE) of 3.08%, which is an enhancement of 85% from that of the cell without ALD-ZnO (PCE = 1.67%). The ultrathin ALD-ZnO was found to act as a curing layer of the surface defects on the hydrothermally grown ZnO NRs, resulting in an improvement in photovoltaic performance.

    Noninvasive characterization of pore size and shape in opaque porous media is a formidable challenge. NMR diffusion-diffraction patterns were found to be exceptionally useful for obtaining such morphological features, but only when pores are monodisperse and coherently placed. When locally anisotropic pores are randomly oriented, conventional diffusion NMR methods fail. Here, we present a simple, direct, and general approach to obtain both compartment size and shape even in such settings and even when pores are characterized by internal field gradients. Using controlled porous media, we show that the bipolar-double-pulsed-field-gradient (bp-d-PFG) methodology yields diffusion-diffraction patterns from which pore size can be directly obtained. Moreover, we show that pore shape, which cannot be obtained by conventional methods, can be directly inferred from the modulation of the signal in angular bp-d-PFG experiments. This new methodology significantly broadens the types of porous media that can be studied using noninvasive diffusion-diffraction NMR.

    Motor recovery of persons after stroke may be enhanced by a novel approach where residual muscle activity is facilitated by patient-controlled electrical muscle activation. Myoelectric activity from hemiparetic muscles is then used for continuous control of functional electrical stimulation (MeCFES) of same or synergic muscles to promote restoration of movements during task-oriented therapy (TOT). Use of MeCFES during TOT may help to obtain a larger functional and neurological recovery than otherwise possible. Multicenter randomized controlled trial. Eighty two acute and chronic stroke victims were recruited through the collaborating facilities and after signing an informed consent were randomized to receive either the experimental (MeCFES assisted TOT (M-TOT) or conventional rehabilitation care including TOT (C-TOT). Both groups received 45 minutes of rehabilitation over 25 sessions. Outcomes were Action Research Arm Test (ARAT), Upper Extremity Fugl-Meyer Assessment (FMA-UE) scores and Disability of the Arm Shoulder and Hand questionnaire. Sixty eight subjects completed the protocol (Mean age 66.2, range 36.5-88.7, onset months 12.7, range 0.8-19.1) of which 45 were seen at follow up 5 weeks later. There were significant improvements in both groups on ARAT (median improvement: MeCFES TOT group 3.0; C-TOT group 2.0) and FMA-UE (median improvement: M-TOT 4.5; C-TOT 3.5). Considering subacute subjects (time since stroke < 6 months), there was a trend for a larger proportion of improved patients in the M-TOT group following rehabilitation (57.9%) than in the C-TOT group (33.2%) (difference in proportion improved 24.7%; 95% CI -4.0; 48.6), though the study did not meet the planned sample size. This is the first large multicentre RCT to compare MeCFES assisted TOT with conventional care TOT for the upper extremity. No adverse events or negative outcomes were encountered, thus we conclude that MeCFES can be a safe adjunct to rehabilitation that could promote recovery of

    In complex biological or colloidal samples, magnetic relaxation dispersion (MRD) experiments using the field-cycling technique can characterize molecular motions on time scales ranging from nanoseconds to microseconds, provided that a rigorous theory of nuclear spin relaxation is available. In gels, cross-linked proteins, and biological tissues, where an immobilized macromolecular component coexists with a mobile solvent phase, nuclear spins residing in solvent (or cosolvent) species relax predominantly via exchange-mediated orientational randomization (EMOR) of anisotropic nuclear (electric quadrupole or magnetic dipole) couplings. The physical or chemical exchange processes that dominate the MRD typically occur on a time scale of microseconds or longer, where the conventional perturbation theory of spin relaxation breaks down. There is thus a need for a more general relaxation theory. Such a theory, based on the stochastic Liouville equation (SLE) for the EMOR mechanism, is available for a single quadrupolar spin I = 1. Here, we present the corresponding theory for a dipole-coupled spin-1/2 pair. To our knowledge, this is the first treatment of dipolar MRD outside the motional-narrowing regime. Based on an analytical solution of the spatial part of the SLE, we show how the integral longitudinal relaxation rate can be computed efficiently. Both like and unlike spins, with selective or non-selective excitation, are treated. For the experimentally important dilute regime, where only a small fraction of the spin pairs are immobilized, we obtain simple analytical expressions for the auto-relaxation and cross-relaxation rates which generalize the well-known Solomon equations. These generalized results will be useful in biophysical studies, e.g., of intermittent protein dynamics. In addition, they represent a first step towards a rigorous theory of water 1H relaxation in biological tissues, which is a prerequisite for unravelling the molecular basis of soft

    Progressive disability in activities of daily living (ADL) is inevitable for people with Alzheimer's disease and related dementias (ADRD). Attempts to slow or prevent ADL disability have been unsuccessful despite making progress in behavioral training methods. Missing from this research is an emphasis on how we maximize a patient's engagement during training and the rigorous examination of implementation protocols (dosing and training methods) which may advantage learning in people with ADRD. Our team addressed this gap with the development of the STOMP (Skill-building through Task-Oriented Motor Practice) intervention which creates methods for obtaining ADL goals that support "personhood" and tests high-intensity protocols that appear to advantage learning and sustained learning over time. Through this study, we aim to evaluate differential outcomes by dose levels as well as assess the moderating effects of attention to task during training. Randomized-controlled trial with 32 participants with dementia assigned to either the original, intensive STOMP protocol (3 hours/day, 5 days/week for 2 weeks) or a less-intensive STOMP protocol (1 hour/day, 2 days/week for 2 weeks) delivered by an occupational therapy assistant in the home. ADL training is delivered using motor learning theory techniques of blocked practice, continuous verbal praise, errorless learning and intense dosing schedules. Inclusion criteria: English speaking, adults 50-80 years old that live with a legally-authorized representative that can provide consent, who can follow a one-step command, have three ADL goals they want to address and can participate in an intense therapy protocol. Exclusions include diagnoses of Creutzfeldt-Jakob Dementia, delirium or receptive/global aphasia. Recruitment will occur through direct mailing, physician referral and media/support group presentations. Blinded occupational therapists will complete baseline, post-intervention and 3-month follow-up assessments in the

    We evaluated a theoretically-derived family-oriented intervention aimed to improve self-efficacy, self-management, glycemic control and quality of life in individuals living with Type 2 diabetes in Thailand. In a single-blinded randomized controlled trial, 140 volunteer individuals with Type 2 diabetes, recruited from a diabetes clinic in rural Thailand, were randomly allocated to intervention and control arms. Those in the intervention arm received routine care plus a family-oriented program that included education classes, group discussions, a home visit, and a telephone follow-up while the control arm only received routine care. Improvement in outcomes over time (baseline, Week 3, and Week 13 following intervention) was evaluated using Generalized Estimating Equations multivariable analyses. Except for age, no between-group significant differences were observed in all other baseline characteristics. Diabetes self-efficacy, self-management, and quality of life improved in the intervention arm but no improvement was observed in the controls. In the risk-adjusted multivariable models, compared to the controls, the intervention arm had significantly better self-efficacy, self-management, outcome expectations, and diabetes knowledge (plife or glycemic control, however, in the risk-adjusted multivariable models, higher self-management scores were associated with significantly decreased HbA1c levels (plife (pfamily-oriented program improved patients' self-efficacy and self-management, which in turn could decrease HbA1c levels.

    There is no clinical evidence that supports the benefit of integrative medicine, defined as combination therapy of oriental and western medicine, on obesity-related hypertension. This study evaluates the efficacy of Bofu-tsusho-san (BOF), an oriental herbal medicine, on the ambulatory blood pressure (BP) profile in hypertensive patients with obesity. The study design was a multicenter, randomized, open-label, parallel-group controlled trial in 107 hypertensive patients with obesity. Participants were randomly assigned to receive either the conventional control therapy or BOF add-on therapy. In both groups antihypertensive therapy was aimed at achieving the target clinic BP. The primary outcome was change in the ambulatory BP profile from baseline to 24 weeks after randomization. Daytime systolic BP variability, an important parameter of ambulatory BP profile, was decreased in the BOF group, and the difference in the changes in daytime systolic BP variability was significant between the BOF and control group (Control vs BOF; the change from baseline in daytime systolic BP variability, 1.0±3.3 vs -1.0±3.3%; p=0.006). The BOF add-on therapy effectively improved the ambulatory BP variability. This is the first report suggesting that an integrative medicine approach may exert favorable effects on obesity-related hypertension compared with conventional pharmaceutical treatment.

    By providing dental health care, dentists dedicate themselves to the preservation and/or improvement of oral health in their patients. By adequately carrying out this care providers' role, dentists will gain recognition, esteem and respect from both patients and colleagues. This analysis aims to assess the patient and professional orientation of dentists and investigate which of their personal and practice characteristics can be regarded determining for these two aspects of their role as care providers. In the year 2000, data was collected via a written questionnaire sent to a random, stratified sample of 790 dentists, of whom 607 (77%) responded. Multivariate regression analysis shows that the preventive treatment concept, professional satisfaction and the number of hours per week that household tasks are performed are positive determinants for dentists' patient orientation. Also, the longer dentists are active in their profession, the more patient oriented they will be, and with more hours per week support from oral hygienists they are less patient oriented. As for professional orientation, dentists' preventive treatment concept and their professional satisfaction can also be considered positive determinants. Furthermore, dentists are more profession oriented when their partner works in the practice, with more hours per week support from oral hygienist(s) and with more collaboration contacts with other care providers. Compared to men, women are on average less profession oriented. Among Dutch dentists, there exist clear differences in the way they take on their role as care providers with regard to patient orientation and professional orientation.

  12. Singularities in primate orientation maps.

    Obermayer, K; Blasdel, G G

    1997-04-01

    We report the results of an analysis of orientation maps in primate striate cortex with focus on singularities and their distribution. Data were obtained from squirrel monkeys and macaque monkeys of different ages. We find the approximately 80% of singularities that are nearest neighbors have the opposite sign and that the spatial distribution of singularities differs significantly from a random distribution of points. We do not find evidence for consistent geometric patterns that singularities may form across the cortex. Except for a different overall alignment of orientation bands and different periods of repetition, maps obtained from different animals and different ages are found similar with respect to the measures used. Orientation maps are then compared with two different pattern models that are currently discussed in the literature: bandpass-filtered white noise, which accounts very well for the overall map structure, and the field analogy model, which specifies the orientation map by the location of singularities and their properties. The bandpass-filtered noise approach to orientation patterns correctly predicts the sign correlations between singularities and accounts for the deviations in the spatial distribution of singularities away from a random dot pattern. The field analogy model can account for the structure of certain local patches of the orientation map but not for the whole map. Neither of the models is completely satisfactory, and the structure of the orientation map remains to be fully explained.

    The advantages of platform switching using narrower abutments remain controversial. Many researchers suggest that platform switching can yield enhanced clinical results, while others remain skeptical. We hypothesize that the effectiveness of platform switching might be associated with the degree of reduction in size of the abutment. To radiographically and clinically examine a new abutment design created to move the implant-abutment interface farther medially. This was a prospective, randomized controlled clinical trial that included 27 patients (41 MIS Lance Plus® implants; MIS Implant Technologies, Karmiel, Israel). The patients' age ranged from 39 to 75 years. At the second stage of the surgery, the implants were randomly assigned to either the new platform switch Tulip abutment (TA) design or to the standard platform abutment (SA). Implant probing depth (IPD) and bleeding on probing (BOP) were recorded at baseline and after 12 months. Standardized periapical radiographs were taken (at baseline and at 12 months) and the marginal bone height measured. All implants were successfully integrated. The mean IPD at 1 year post-op was 2.91 mm for the SA group and 2.69 mm for the TA group (p > .05). Similarly, the BOP at 1 year was almost identical in both groups. The mean values of bone resorption at baseline were 0.98 ± 0.37 mm and 0.69 ± 0.20 for the TA and SA groups, respectively (p > .05). Bone loss (baseline to 12 months) was significantly greater in the SA group compared with the TA group. Use of the new TA, with its significantly downsized diameter, resulted in reduced bone loss at 1 year. Further research will be required to assess the long-term effect of this abutment on peri-implant health. © 2014 Wiley Periodicals, Inc.

The authors contend that advances in the field are primarily encumbered by the lack of distinct boundaries and definitions. Here, hypnosis, trance, and mind are all redefined and grounded in biological, neurological, and psychological phenomena. Solutions are proposed for boundary and language problems associated with hypnosis. The biological role of novelty stimulating an orienting response that, in turn, potentiates systemic plasticity forms the basis for trance. Hypnosis is merely the skill set that perpetuates and influences trance. This formulation meshes with many aspects of Milton Erickson's legacy and Ernest Rossi's recent theory of mind and health. Implications of this hypothesis for clinical skills, professional training, and research are discussed.

    priority of the discovery in the literature, which was partly caused by the existence of the Iron Curtain. I had already enjoyed contact with Boris in the 1980s when the two volumes of Landau Level Spectroscopy were being prepared [2]. He was one of the pioneers of magneto-optics in semiconductors. In the 1950s the band structure of germanium and silicon was investigated by magneto-optical methods, mainly in the United States. No excitonic effects were observed and the band structure parameters were determined without taking account of excitons. However, working with cuprous oxide, which is a direct semiconductor with a relative large energy gap, Zakharchenya and his co-worker Seysan showed that in order to obtain correct band structure parameters, it is necessary to take excitons into account [3]. About 1970 Boris started work on optical orientation. Early work by Hanle in Germany in the 1920s on the depolarization of luminescence in mercury vapour by a transverse magnetic field was not appreciated for a long time. Only in the late 1940s did Kastler and co-workers in Paris begin a systematic study of optical pumping, which led to the award of a Nobel prize. The ideas of optical pumping were first applied by Georges Lampel to solid state physics in 1968. He demonstrated optical orientation of free carriers in silicon. The detection method was nuclear magnetic resonance; optically oriented free electrons dynamically polarized the 29Si nuclei of the host lattice. The first optical detection of spin orientation was demonstrated by with the III-V semiconductor GaSb by Parsons. Due to the various interaction mechanisms of spins with their environment, the effects occurring in semiconductors are naturally more complex than those in atoms. Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light is deduced from the degree of circular polarization of the recombination

    Azobenzene molecules and their derivatives have been widely investigated for their potential applications in optical and electrooptical devices. We have prepared a new guest-host system from natural rubber (NR) impregnated with azobenzene derivative Sudan Red B (SRB). The effects of stretching and immersion time on photoinduced orientation were investigated by birefringence signal measurements. We have found that the molecular orientation increase when the samples are stretched and decrease with the increase of immersion time. The first behavior was explained by using the random coil model and the latter was attributed to increase of the aggregation of SRB into NR matrix.

The scale is based on a clear definition of the content of the construct of market orientation in the hospital industry. To this end, a national random sample of 237 hospital administrators was used. In addition to the support for the reliability and validity, the scale promises parsimony, pragmatism, and wide-ranging applicability.

    Using a 4x4 transfer matrix method, localized modes in orientation-disordered uniaxial medium have been investigated. We confirm that localized modes origin from the randomness of spatial orientation of optical axes. The misalignment of the optical axe provides the opportunity for a rearrangement of the localized modes. The number of localize mode also closely relative to the spatial orientation of optical axis. Numerical results indicate that it is possible to adjust the localized modes through altering the relative orientation of the optical axes of scatterers. This study is an importance for well understanding of localization of light wave and lasing action in anisotropic random media.

Information from at least four distributed databases functioning independently is brought together in a single paper document. Informationally, STOR is prioritized, displays inter-problem and chronological relationships, provides a high degree of physician control over the display and provides a great deal of information with little manual physician effort. Besides the usual issues of cost, impact, and acceptance, the evaluation will address the question of the informational competence of STOR in two single blind randomized controlled trials.

  2. WITHDRAWN: Reality orientation for dementia.

    Science.gov (United States)

    Spector, A; Orrell, M; Davies, S; Woods, B

    2007-07-18

    Reality Orientation (RO) was first described as a technique to improve the quality of life of confused elderly people, although its origins lie in an attempt to rehabilitate severely disturbed war veterans, not in geriatric work. It operates through the presentation of orientation information (eg time, place and person-related) which is thought to provide the person with a greater understanding of their surroundings, possibly resulting in an improved sense of control and self-esteem. There has been criticism of RO in clinical practice, with some fear that it has been applied in a mechanical fashion and has been insensitive to the needs of the individual. There is also a suggestion that constant relearning of material can actually contribute to mood and self-esteem problems. There is often little consistent application of psychological therapies in dementia services, so a systematic review of the available evidence is important in order to identify the effectiveness of the different therapies. Subsequently, guidelines for their use can be made on a sound evidence base. To assess the evidence of effectiveness for the use of Reality Orientation (RO) as a classroom-based therapy on elderly persons with dementia. Computerised databases were searched independently by 2 reviewers entering the terms 'Reality Orientation, dementia, control, trial or study'. Relevant web sites were searched and some hand searching was conducted by the reviewer. Specialists in the field were approached for undocumented material, and all publications found were searched for additional references. All randomized controlled trials (RCTs), and all controlled trials with some degree of concealment, blinding or control for bias (second order evidence) of Reality Orientation as an intervention for dementia were included. The criteria for inclusion/exclusion involved systematic assessment of the quality of study design and the risk of bias, using a standard data extraction form. A measure of

    We study the sedimentation of non-spherical particles in turbulence. The particle orientation is determined by a competition between inertial torques causing a preferential alignment and turbulence randomizing the orientation. The relative importance is quantified by a settling number SF defined as the ratio of the tumbling-rate from inertial torques and from turbulence. The experiments focus on the orientation statistics of particles formed from several slender arms, including fibers and particles with three arms in planar symmetry (triads), which allows us to study alignment of both fibers and disk-like particles. We measure the time-resolved 3D orientations of the particles along with the fluid velocity field around them in a vertical water tunnel. An active jet array with 40 individually controllable jets enables us to adjust the turbulence intensity and observe the transition from strongly aligned particles to randomized orientations as SF is decreased. Results are compared to simulations and theory based on slender body theory.

    I begin the article with an account of the background to the German debate on ‘Literaturwissenschaft als Kulturwissenschaft’, including the introduction of the concept of ’cultural orientation’ as a strategy for achieving interdisciplinarity. This is followed by a consideration of the discussion...... of the object of literary studies as a way of defining the disciplinarity or identity of literary studies. Finally I summarize some of the characteristics of culturally orientated literary studies....

    Detection elements play a key role in analyte recognition in biosensors. Therefore, detection elements with high analyte specificity and binding strength are required. While antibodies (Abs) have been increasingly used as detection elements in biosensors, a key challenge remains - the immobilization on the biosensor surface. This minireview highlights recent approaches to immobilize and study Abs on surfaces. We first introduce Ab species used as detection elements, and discuss techniques recently used to elucidate Ab orientation by determination of layer thickness or surface topology. Then, several immobilization methods will be presented: non-covalent and covalent surface attachment, yielding oriented or random coupled Abs. Finally, protein modification methods applicable for oriented Ab immobilization are reviewed with an eye to future application.

    partial orientation between inclusion and host. A (111) plane of each inclusion is sub-parallel to a {111} plane of their diamond host, but with random orientations of the magnesiochromite [100], [010] and [001] relative to the diamond. In one case, where a single inclusion comprised a magnesiochromite-olivine touching pair, the magnesiochromite was oriented as noted above and the olivine showed a random orientation. The implications of these observations for the mechanisms of diamond growth will be explored and the results will be compared and combined with previous work.

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

    2003-12-01

    A mail survey of a national random sample of 2,000 marketing managers was conducted. The data provided by 222 respondents were analyzed to assess the dimensionality of Narver and Slater's 15-item measure of market orientation. A confirmatory factor analysis, using LISREL 8.53, provided support for each of the separate dimensions of customer orientation, competitor orientation, and interfunctional coordination. However, a combined 3-factor model of market orientation was not supported. Directions for research are suggested.

    2013-01-01

    Full Text Available Changes in today's business environment require companies to orient to strategic marketing. The company accepting strategic marketing has a proactive approach and focus on continuous review and reappraisal of existing and seeking new strategic business areas. Difficulties in achieving target profit and growth require turning marketing from the dominant viewpoint of the tangible product to creating superior value and developing relationships with customers. Value orientation implies gaining competitive advantage through continuous research and understanding of what value represents to the consumers and discovering new ways to meet their required values. Strategic marketing investment requires that the investment in the creation of values should be regularly reviewed in order to ensure a focus on customers with high profit potential and environmental value. This increases customer satisfaction and retention and long-term return on investment of companies.

  7. Aspect-Oriented Programming

    Elrad, Tzilla (Editor); Filman, Robert E. (Editor); Bader, Atef (Editor)

    2001-01-01

    Computer science has experienced an evolution in programming languages and systems from the crude assembly and machine codes of the earliest computers through concepts such as formula translation, procedural programming, structured programming, functional programming, logic programming, and programming with abstract data types. Each of these steps in programming technology has advanced our ability to achieve clear separation of concerns at the source code level. Currently, the dominant programming paradigm is object-oriented programming - the idea that one builds a software system by decomposing a problem into objects and then writing the code of those objects. Such objects abstract together behavior and data into a single conceptual and physical entity. Object-orientation is reflected in the entire spectrum of current software development methodologies and tools - we have OO methodologies, analysis and design tools, and OO programming languages. Writing complex applications such as graphical user interfaces, operating systems, and distributed applications while maintaining comprehensible source code has been made possible with OOP. Success at developing simpler systems leads to aspirations for greater complexity. Object orientation is a clever idea, but has certain limitations. We are now seeing that many requirements do not decompose neatly into behavior centered on a single locus. Object technology has difficulty localizing concerns invoking global constraints and pandemic behaviors, appropriately segregating concerns, and applying domain-specific knowledge. Post-object programming (POP) mechanisms that look to increase the expressiveness of the OO paradigm are a fertile arena for current research. Examples of POP technologies include domain-specific languages, generative programming, generic programming, constraint languages, reflection and metaprogramming, feature-oriented development, views/viewpoints, and asynchronous message brokering.

  10. Reality orientation for dementia.

    Science.gov (United States)

    Spector, A; Orrell, M; Davies, S; Woods, B

    2000-01-01

    Reality Orientation (RO) was first described as a technique to improve the quality of life of confused elderly people, although its origins lie in an attempt to rehabilitate severely disturbed war veterans, not in geriatric work. It operates through the presentation of orientation information (eg time, place and person-related) which is thought to provide the person with a greater understanding of their surroundings, possibly resulting in an improved sense of control and self-esteem. There has been criticism of RO in clinical practice, with some fear that it has been applied in a mechanical fashion and has been insensitive to the needs of the individual. There is also a suggestion that constant relearning of material can actually contribute to mood and self-esteem problems. There is often little consistent application of psychological therapies in dementia services, so a systematic review of the available evidence is important in order to identify the effectiveness of the different therapies. Subsequently, guidelines for their use can be made on a sound evidence base. To assess the evidence of effectiveness for the use of Reality Orientation (RO) as a classroom-based therapy on elderly persons with dementia. Computerised databases were searched independently by 2 reviewers entering the terms 'Reality Orientation, dementia, control, trial or study'. Relevant websites were searched and some handsearching was conducted by the reviewer. Specialists in the field were approached for undocumented material, and all publications found were searched for additional references. All randomised controlled trials (RCTs), and all controlled trials with some degree of concealment, blinding or control for bias (second order evidence) of Reality Orientation as an intervention for dementia were included. The criteria for inclusion/exclusion involved systematic assessment of the quality of study design and the risk of bias, using a standard data extraction form. A measure of cognitive

The relationships between different behavioural aspects of political market orientation and the attitudinal influences of such behaviour are analysed, and the study includes structural equation...... modelling to test several hypotheses. While the results show that political parties focus on several different aspects of market-oriented behaviour, especially using an internal and societal orientation as cultural antecedents, a more surprising result is the inconclusive effect of a voter orientation...... on political market orientation.

  13. The Sexual Orientation Cases

    Directory of Open Access Journals (Sweden)

    Loveland Ian

    2017-05-01

    Full Text Available This paper assesses Scalia’s contribution to a series of cases, spanning much of his thirty years tenure on the court, which addressed issues relating to sexual orientation discrimination. The argument put forward is that these cases severely undermine any claim that Scalia might make to having been a distinguished judge in an intellectual or juridical sense. The pervasive theme of Scalia’s opinions in these matters is that of a constant failure to respect traditional tenets of legal reasoning and a compulsive inclination to engage in abusive castigation both of the litigants challenging the discriminatory laws and his judicial colleagues who did not agree with his viewpoint.

  15. Teachers' orientations towards writing

    Directory of Open Access Journals (Sweden)

    Sarah J. McCarthey & Dumisile Mkhize

    2013-06-01

    Full Text Available This study of 29 teachers from four states in the US investigated teachers' orientations towards writing and the influences on their beliefs. Through interviews about writing instruction, the researchers found significant differences between teachers in high and low-income schools. While teachers in high-income schools valued rhetorical style, developing voice, and reading-writing connections, teachers in low-income schools focused on grammar, mechanics and sentence structure. Teachers in high-income schools appear to be exercising more choice in curricular materials and valuing quality of writing beyond grammar and mechanics, whereas teachers in low-income schools are using specific curriculum mandated by the districts. Influences on teachers' orientations included school context, programs and materials, and assessments. The study raises concerns that students in low-income schools are missing out on authentic, challenging, and meaningful writing opportunities since the focus is on skills-based instruction. The findings point to the need for teachers to provide all students with opportunities to develop rhetorical style, voice, and reading-writing connections in addition to grammar, mechanics, and sentence structure.

    Full Text Available On October 10, 1947, the University of Oriente is founded with the presence of local authorities and the historic Bell of the Damajagua. Since then it has generated outstanding events that have drawn guidelines in its history. These landmarks have taken place in different spheres of social, political and economic life. We have found that most workers and students from the University know less than fifty percent of such events, and we assume that the population outside the walls must have a greater ignorance. The present paper aims to spread these crucial events because knowing them will help appreciate better the real prestige of this house of higher learning through its rich  history, which will result in feelings of admiration and respect for this university. Thus, it is necessary to make a wider propagation through the press, radio and television programs and digital media such as Multimedia, Web Pages and the Internet.The theme landmark at the Universidad de Oriente of the subject Historical and Contemporary Debates implemented in the disciplines of all careers at this university gives freshmen the opportunity to investigate and learn about these remarkable  facts with some impact outside our national territory.

  7. French Orientational Accent

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available The history of describing the French final accent – and French accentuation in general – is fulfilled by different and very heterogenous approaches, analyzing this prosodic feature in French from both substantial and functional points of view. Viewed through pragmatical frame, the final accent is a one of the key aspects in shaping the acoustical image of spoken French and b a strategic tool for the speaker to build the coherence and sense of uttering. The distribution of final accents, i. e. forming accentual units, helps the speaker and his adressee to form a refined strategy in generating and perceiving the spoken text. From the discourse point of view it is therefore justified to define the French final accent as an orientational prosodic feature.

  8. Spiritually oriented psychodynamic psychotherapy.

    Shafranske, Edward P

    2009-02-01

    Spiritually oriented psychodynamic psychotherapy pays particular attention to the roles that religious and spiritual beliefs, practices, and experiences play in the psychological life of the client. Contemporary psychoanalytic theorists offer multiple approaches to understand the functions of religious experience. Spirituality provides a means to address existential issues and provide a context to form personal meaning. Religious narratives present schemas of relationship and models of experiences salient to mental health, such as hope. God images or other symbolic representations of the transcendent have the power to evoke emotions, which in turn, influence motivation and behavior. While employing theories and techniques derived from psychodynamic psychotherapy, this therapeutic approach encourages the analysis of the functions religion and spirituality serve, while respecting the client's act of believing in faith. Psychotherapists address a client's spirituality by exploring the psychological meaning of such personal commitments and experiences and refrain from entering into discussion of faith claims.

    Oriental cholangiohepatitis (OCH) also called recurrent pyogenic cholangitis is characterized by intrahepatic duct calculi, strictures, and recurrent infections. In turn cholangitis can result in multiple hepatic abscesses, further biliary strictures, and in severe cases, progressive hepatic parenchymal destruction, cirrhosis, and portal hypertension. Magnetic resonance cholangiopancreatography (MRCP) and conventional T1-weighted (T1 W) and T2-weighted (T2 W) magnetic resonance imaging (MRI) findings have been described in patients with OCH. MRCP findings include duct dilation, strictures, and calculi. MRCP can help to localize the diseased ducts and determine the severity of involvement. T1 and T2 W sequences reveal the parenchymal changes of atrophy, abscess formation, and portal hypertension in addition to calculi. Post-treatment changes are also well depicted using MRI. Comprehensive, non-invasive assessment is achieved by using conventional MRI and MRCP in OCH providing a roadmap for endoscopic or surgical management.

    Musa, Atiyyah; Gong, Rong Hugh; Nasir, Eryna; Baharudin, Aznin; Tulos, Najua

    2016-02-01

    The aim of this research is to produce some three-dimensional (3D) nonwoven fabrics with variation in weight and type of fibre and then analyse their fibre orientation distribution by fast Fourier Transform (FFT) method. Three different fibres were used: polyester, polypropylene and blended polyester and polypropylene. Fabric weight varied from 20 to 180 g/m2. The processes of web formation and consolidation were based on the principle of air-laid and hot through-air thermal bonding technique. The result of the fibre orientation showed a random distribution of the fibres for all the samples. It indicated that there was no relationship between the variables and fibre orientation distribution. The position of 3D web whether from the top or side part did not show any variation and thus they did not have the influence towards the fibre orientation.

    Bensmail, Julien; Renault, Gabriel

    2016-01-01

    An undirected graph G is locally irregular if every two of its adjacent vertices have distinct degrees. We say that G is decomposable into k locally irregular graphs if there exists a partition E1∪E2∪⋯∪Ek of the edge set E(G) such that each Ei induces a locally irregular graph. It was recently...... conjectured by Baudon et al. that every undirected graph admits a decomposition into at most three locally irregular graphs, except for a well-characterized set of indecomposable graphs. We herein consider an oriented version of this conjecture. Namely, can every oriented graph be decomposed into at most...... three locally irregular oriented graphs, i.e. whose adjacent vertices have distinct outdegrees? We start by supporting this conjecture by verifying it for several classes of oriented graphs. We then prove a weaker version of this conjecture. Namely, we prove that every oriented graph can be decomposed...

  18. Value oriented marketing strategies

    Directory of Open Access Journals (Sweden)

    Stanković Ljiljana

    2009-01-01

    Full Text Available The complexity of business environment imposes the need for continuous change and reexamination of business marketing strategies of enterprises. Theory and practice of strategic management and marketing show that the activities of marketing, which are closely connected to corporate strategy, are the key drivers of growth. There is a positive correlation between competition intensity, marketing strategy and business performance of companies. Even though, managers of many companies don't see a clear connection between marketing strategy and business performance, numerous empirical research show that the companies which possess and efficiently use marketing resources and capabilities are more successful. In knowledge-based economics, the development of value oriented marketing strategies for all participants in the chain is a supposition of the survival, growth and development of companies. Competitive advantage is the essence of any strategy. Acquisition and maintenance of competitive advantage is more successful if the potentials for value creation are used efficiently. The paper examines the critical factors that influence alignment and transformation of marketing strategies in accordance with changes in value estimation. Superior value, is created in different network classes. Theory and practice researches create a reliable basis for the development of new concepts, marketing strategy business models that will contribute to competitive advantage of enterprises and the economy.

  20. Device Oriented Project Controller

    Dalesio, Leo; Kraimer, Martin

    2013-11-20

    This proposal is directed at the issue of developing control systems for very large HEP projects. A de-facto standard in accelerator control is the Experimental Physics and Industrial Control System (EPICS), which has been applied successfully to many physics projects. EPICS is a channel based system that requires that each channel of each device be configured and controlled. In Phase I, the feasibility of a device oriented extension to the distributed channel database was demonstrated by prototyping a device aware version of an EPICS I/O controller that functions with the current version of the channel access communication protocol. Extensions have been made to the grammar to define the database. Only a multi-stage position controller with limit switches was developed in the demonstration, but the grammar should support a full range of functional record types. In phase II, a full set of record types will be developed to support all existing record types, a set of process control functions for closed loop control, and support for experimental beam line control. A tool to configure these records will be developed. A communication protocol will be developed or extensions will be made to Channel Access to support introspection of components of a device. Performance bench marks will be made on both communication protocol and the database. After these records and performance tests are under way, a second of the grammar will be undertaken.

  6. Postdictive modulation of visual orientation.

    Directory of Open Access Journals (Sweden)

    Takahiro Kawabe

    Full Text Available The present study investigated how visual orientation is modulated by subsequent orientation inputs. Observers were presented a near-vertical Gabor patch as a target, followed by a left- or right-tilted second Gabor patch as a distracter in the spatial vicinity of the target. The task of the observers was to judge whether the target was right- or left-tilted (Experiment 1 or whether the target was vertical or not (Supplementary experiment. The judgment was biased toward the orientation of the distracter (the postdictive modulation of visual orientation. The judgment bias peaked when the target and distracter were temporally separated by 100 ms, indicating a specific temporal mechanism for this phenomenon. However, when the visibility of the distracter was reduced via backward masking, the judgment bias disappeared. On the other hand, the low-visibility distracter could still cause a simultaneous orientation contrast, indicating that the distracter orientation is still processed in the visual system (Experiment 2. Our results suggest that the postdictive modulation of visual orientation stems from spatiotemporal integration of visual orientation on the basis of a slow feature matching process.

  8. Oriented active shape models.

    Science.gov (United States)

    Liu, Jiamin; Udupa, Jayaram K

    2009-04-01

    Active shape models (ASM) are widely employed for recognizing anatomic structures and for delineating them in medical images. In this paper, a novel strategy called oriented active shape models (OASM) is presented in an attempt to overcome the following five limitations of ASM: 1) lower delineation accuracy, 2) the requirement of a large number of landmarks, 3) sensitivity to search range, 4) sensitivity to initialization, and 5) inability to fully exploit the specific information present in the given image to be segmented. OASM effectively combines the rich statistical shape information embodied in ASM with the boundary orientedness property and the globally optimal delineation capability of the live wire methodology of boundary segmentation. The latter characteristics allow live wire to effectively separate an object boundary from other nonobject boundaries with similar properties especially when they come very close in the image domain. The approach leads to a two-level dynamic programming method, wherein the first level corresponds to boundary recognition and the second level corresponds to boundary delineation, and to an effective automatic initialization method. The method outputs a globally optimal boundary that agrees with the shape model if the recognition step is successful in bringing the model close to the boundary in the image. Extensive evaluation experiments have been conducted by utilizing 40 image (magnetic resonance and computed tomography) data sets in each of five different application areas for segmenting breast, liver, bones of the foot, and cervical vertebrae of the spine. Comparisons are made between OASM and ASM based on precision, accuracy, and efficiency of segmentation. Accuracy is assessed using both region-based false positive and false negative measures and boundary-based distance measures. The results indicate the following: 1) The accuracy of segmentation via OASM is considerably better than that of ASM; 2) The number of landmarks

  10. Practising orientation identification improves orientation coding in V1 neurons.

    Science.gov (United States)

    Schoups, A; Vogels, R; Qian, N; Orban, G

    2001-08-02

    The adult brain shows remarkable plasticity, as demonstrated by the improvement in fine sensorial discriminations after intensive practice. The behavioural aspects of such perceptual learning are well documented, especially in the visual system. Specificity for stimulus attributes clearly implicates an early cortical site, where receptive fields retain fine selectivity for these attributes; however, the neuronal correlates of a simple visual discrimination task remained unidentified. Here we report electrophysiological correlates in the primary visual cortex (V1) of monkeys for learning orientation identification. We link the behavioural improvement in this type of learning to an improved neuronal performance of trained compared to naive neurons. Improved long-term neuronal performance resulted from changes in the characteristics of orientation tuning of individual neurons. More particularly, the slope of the orientation tuning curve that was measured at the trained orientation increased only for the subgroup of trained neurons most likely to code the orientation identified by the monkey. No modifications of the tuning curve were observed for orientations for which the monkey had not been trained. Thus training induces a specific and efficient increase in neuronal sensitivity in V1.

    Schweighofer, Nicolas; Choi, Younggeun; Winstein, Carolee; Gordon, James

    2012-11-01

    Task-oriented training is emerging as the dominant and most effective approach to motor rehabilitation of upper extremity function after stroke. Here, the authors propose that the task-oriented training framework provides an evidence-based blueprint for the design of task-oriented robots for the rehabilitation of upper extremity function in the form of three design principles: skill acquisition of functional tasks, active participation training, and individualized adaptive training. The previous robotic systems that incorporate elements of task-oriented trainings are then reviewed. Finally, the authors critically analyze their own attempt to design and test the feasibility of a TOR robot, ADAPT (Adaptive and Automatic Presentation of Tasks), which incorporates the three design principles. Because of its task-oriented training-based design, ADAPT departs from most other current rehabilitation robotic systems: it presents realistic functional tasks in which the task goal is constantly adapted, so that the individual actively performs doable but challenging tasks without physical assistance. To maximize efficacy for a large clinical population, the authors propose that future task-oriented robots need to incorporate yet-to-be developed adaptive task presentation algorithms that emphasize acquisition of fine motor coordination skills while minimizing compensatory movements.

    Objective. Target selectivity of deep brain stimulation (DBS) therapy is critical, as the precise locus and pattern of the stimulation dictates the degree to which desired treatment responses are achieved and adverse side effects are avoided. There is a clear clinical need to improve DBS technology beyond currently available stimulation steering and shaping approaches. We introduce orientation selective neural stimulation as a concept to increase the specificity of target selection in DBS. Approach. This concept, which involves orienting the electric field along an axonal pathway, was tested in the corpus callosum of the rat brain by freely controlling the direction of the electric field on a plane using a three-electrode bundle, and monitoring the response of the neurons using functional magnetic resonance imaging (fMRI). Computational models were developed to further analyze axonal excitability for varied electric field orientation. Main results. Our results demonstrated that the strongest fMRI response was observed when the electric field was oriented parallel to the axons, while almost no response was detected with the perpendicular orientation of the electric field relative to the primary fiber tract. These results were confirmed by computational models of the experimental paradigm quantifying the activation of radially distributed axons while varying the primary direction of the electric field. Significance. The described strategies identify a new course for selective neuromodulation paradigms in DBS based on axonal fiber orientation.

    Many animals use the sun's polarization pattern to orientate, but the dung beetle Scarabaeus zambesianus is the only animal so far known to orientate using the million times dimmer polarization pattern of the moonlit sky. We demonstrate the relative roles of the moon and the nocturnal polarized-light pattern for orientation. We find that artificially changing the position of the moon, or hiding the moon's disc from the beetle's field of view, generally did not influence its orientation performance. We thus conclude that the moon does not serve as the primary cue for orientation. The effective cue is the polarization pattern formed around the moon, which is more reliable for orientation. Polarization sensitivity ratios in two photoreceptors in the dorsal eye were found to be 7.7 and 12.9, similar to values recorded in diurnal navigators. These results agree with earlier results suggesting that the detection and analysis of polarized skylight is similar in diurnal and nocturnal insects. PMID:15101694

    In the last two decades, it has been established that a single universal probability distribution function, known as the Tracy-Widom (TW) distribution, in many cases provides a macroscopic-level description of the statistical properties of microscopically different systems, including both purely mathematical ones, such as increasing subsequences in random permutations, and quite physical ones, such as directed polymers in random media or polynuclear crystal growth. In the first part of this review, we use a number of models to examine this phenomenon at a simple qualitative level and then consider the exact solution for one-dimensional directed polymers in a random environment, showing that free energy fluctuations in such a system are described by the universal TW distribution. The second part provides detailed appendix material containing the necessary mathematical background for the first part. (reviews of topical problems)

    Cells are extremely crowded, and a central question in biology is how this affects the intracellular water. Here, we use ultrafast vibrational spectroscopy and dielectric-relaxation spectroscopy to observe the random orientational motion of water molecules inside living cells of three prototypical organisms: Escherichia coli, Saccharomyces cerevisiae (yeast), and spores of Bacillus subtilis. In all three organisms, most of the intracellular water exhibits the same random orientational motion as neat water (characteristic time constants ~9 and ~2 ps for the first-order and second-order orientational correlation functions), whereas a smaller fraction exhibits slower orientational dynamics. The fraction of slow intracellular water varies between organisms, ranging from ~20% in E. coli to ~45% in B. subtilis spores. Comparison with the water dynamics observed in solutions mimicking the chemical composition of (parts of) the cytosol shows that the slow water is bound mostly to proteins, and to a lesser extent to other biomolecules and ions.The cytoplasm's crowdedness leads one to expect that cell water is different from bulk water. By measuring the rotational motion of water molecules in living cells, Tros et al. find that apart from a small fraction of water solvating biomolecules, cell water has the same dynamics as bulk water.

    Since the publication of Random Matrices (Academic Press, 1967) so many new results have emerged both in theory and in applications, that this edition is almost completely revised to reflect the developments. For example, the theory of matrices with quaternion elements was developed to compute certain multiple integrals, and the inverse scattering theory was used to derive asymptotic results. The discovery of Selberg's 1944 paper on a multiple integral also gave rise to hundreds of recent publications. This book presents a coherent and detailed analytical treatment of random matrices, leading

  6. Can we change sexual orientation?

    2012-02-01

    The self-reports of individuals who claim that they have changed their sexual orientation are either dismissed as false or relied upon to promote sexual orientation change efforts. However, these reactions do not capture the complexity of the sexual reorientation phenomenon. This article provides an overview regarding the promise and effort of sexual reorientation and how this knowledge may inform our current understanding of human sexuality. Specifically, a brief history is given of the interventions used to change attractions to same-sex adults and the assumptions underlying these efforts. Information will be given regarding which conclusions can be derived from sexual reorientation studies. The limitations of these studies will be explained to strengthen future research. Hypotheses will be presented regarding the motivations and needs of those distressed by a same-sex erotic orientation and the impact that the hope of sexual reorientation may have for family members, religious leaders, and policy makers. A multivariate model of sexuality and sexual orientation, including scales of attraction and aversion, will be proposed based upon current understanding of sexuality and the distinctions found in sexual reorientation research. In the end, a therapeutic framework will be highlighted that may be used (and researched) to help those distressed by their sexual orientation.

  7. Subfilter scalar-flux vector orientation in homogeneous isotropic turbulence.

    Verma, Siddhartha; Blanquart, G

    2014-06-01

    The geometric orientation of the subfilter-scale scalar-flux vector is examined in homogeneous isotropic turbulence. Vector orientation is determined using the eigenframe of the resolved strain-rate tensor. The Schmidt number is kept sufficiently large so as to leave the velocity field, and hence the strain-rate tensor, unaltered by filtering in the viscous-convective subrange. Strong preferential alignment is observed for the case of Gaussian and box filters, whereas the sharp-spectral filter leads to close to a random orientation. The orientation angle obtained with the Gaussian and box filters is largely independent of the filter width and the Schmidt number. It is shown that the alignment direction observed numerically using these two filters is predicted very well by the tensor-diffusivity model. Moreover, preferred alignment of the scalar gradient vector in the eigenframe is shown to mitigate any probable issues of negative diffusivity in the tensor-diffusivity model. Consequentially, the model might not suffer from solution instability when used for large eddy simulations of scalar transport in homogeneous isotropic turbulence. Further a priori tests indicate poor alignment of the Smagorinsky and stretched vortex model predictions with the exact subfilter flux. Finally, strong filter dependence of subfilter scalar-flux orientation suggests that explicit filtering may be preferable to implicit filtering in large eddy simulations.

    Full Text Available Orientation: In an increasingly turbulent business context in which people are less dependent on organisational career arrangements and have greater agency in career decisions, organisations have come to pay increasing attention to retaining valuable talented managerial potential.Research purpose: The study empirically assessed the causal influence of individuals’ career orientations on their perceived life satisfaction, job or career satisfaction, sense of happiness and their perceptions of work as a valuable activity as aspects of their subjective work experiences.Motivation for study: From an organisational perspective, research on individuals’ inner definitions of career success and satisfaction is needed to guide current selection, placement, development, reward and retention practices.Research design, approach and method: A quantitative survey was conducted on a random sample of 2997 participants at predominantly managerial and supervisory level in the service industry. The measuring instruments consisted of an adapted five-factor career orientations model of the Career Orientations Inventory and a 4-item global subjective work experiences scale. Structural equation modelling (SEM was conducted to achieve the aim of the study.Main findings/results: Statistically significant causal relationships were observed between the career orientations and subjective work experiences variables.Practical implications: Individuals’ career orientations influence their general sense of life and job or career satisfaction, happiness and perceptions of work as a valuable activity. Organisations concerned with the retention of staff need to find a way of aligning individuals’ career needs and motives with the goals and aspirations of the organisation.Contribution/value-add: The research confirms the need for assessing the inner career orientations of employees as these provide valuable information regarding the motives and values driving individuals

    1995-09-01

    Curriculum theorists have acknowledged the critical role that beliefs and values play in the decisions that teachers make, but very little is known about how teachers' value profiles develop. The purpose of this investigation was to examine the educational value orientations of a group of physical education preservice teachers (N = 16) enrolled in an elementary methods course and to investigate the link between value profiles and teacher behaviors. Value profiles were assessed using the Value Orientation Inventory (Ennis & Hooper, 1988). The results indicated that teachers in training entered field-based experiences with defined value profiles, but that these profiles were not stable constructs. Priorities within competing value orientations fluctuated over the course of a semester. Possible explanations for the changes that occurred and implications for teacher education programs are discussed.

    2011-08-15

    Lesbian, gay, and bisexual populations are not part of cancer surveillance, resulting in scarce information about the cancer survivorship of these populations. To address this information gap, the authors examined the prevalence of cancer survivorship by sexual orientation and cancer survivors' self-reported health by sexual orientation. The authors explored these issues by analyzing pooled data from the California Health Interview survey from 2001, 2003, and 2005. By using descriptive statistics and logistic regressions, they examined the cancer prevalence in men and women by sexual orientation and subsequently compared the self-reported health of male and female cancer survivors by sexual orientation. Among women, the authors found no significant differences in cancer prevalence by sexual orientation, but lesbian and bisexual female cancer survivors had 2.0 and 2.3× the odds of reporting fair or poor health compared with heterosexual female cancer survivors. Among men, we found significant differences in cancer prevalence, with gay men having 1.9× the odds of reporting a cancer diagnosis compared with heterosexual men. There were no differences by sexual orientation in male cancer survivors' self-reported health. Our novel findings suggest sex differences in the impact of cancer on lesbian, gay, and bisexual cancer survivors. Lesbian and bisexual cancer survivors need to be targeted by programs and services to assist these cancer survivors in improving their health perceptions, whereas healthcare providers and public health agencies need to be made aware of the higher prevalence of cancer in gay men to prevent future cancers through increased screening and primary prevention.

    Temporal orientation is a component of most screening tests for diagnosing cognitive impairment. Correct temporal orientation involves activating both semantic information (concepts of the calendar date) and episodic information (remembering the current date). The aim of this study was to assess the diagnostic usefulness of a technique for evaluating temporal orientation, which was open-ended, and scoring the semantic and episodic information thus generated (0-10 points). A total of 24 subjects without impairment, 77 patients with mild cognitive impairment (MCI) and 62 patients with dementia were evaluated by means of a 30-point mini-mental/mini-examination, semantic verbal fluency test, global deterioration scale, mini-mental-type temporal orientation and open-ended temporal orientation tests. The areas under the curve (aROC), sensitivity and specificity for dementia and cognitive impairment at any degree (MCI and dementia) were analysed. Open-ended temporal orientation presented a greater area under the curve (aROC: 0.90) for discrimination between patients with dementia and without dementia (MCI and without impairment) and an aROC of 0.83 for discrimination between patients with MCI or dementia and without impairment. For dementia, with a cut-off point equal to or below 6, sensitivity was 0.96 and specificity was 0.68, and for MCI with dementia, with a cut-off point equal to or below 7, sensitivity was 0.72 and specificity was 0.92. The usefulness, conciseness and strategic position of this technique in examining mental status make it suitable as an instrument for screening for cognitive impairment. It has a high level of sensitivity with low specificity for dementia and low sensitivity with high specificity for any degree of impairment.

    Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

    Full Text Available Orientation plays a vital role for organizations to compete to create sustainable competitive advantage. The objective of this study is to examine the relationship between market orientation (MO and organizational performance (OP with service quality (SQ as a moderator in the context of the hotel industry in Malaysia. MO and OP were conceptualized as three- and two-dimensional constructs, respectively, whereas SQ, which consists of two-dimensional constructs, namely, technical quality and functional quality, was used as a moderator. Data were gathered through a survey using a structured questionnaire with a sample of 187 executive-level employees employed in hotels rated three stars and above in Malaysia. SmartPLS 2.0 (M3 with path modeling and bootstrapping was used to examine the standard error of the estimate and t-values. The findings suggest that only competitor orientation dimension of MO was significantly related to OP, whereas customer orientation and inter-functional coordination were not related. Interestingly, SQ was found to have moderated the relationship between MO and performance of the hotels in Malaysia. SQ exists to fill in the gap between customers’ expectations and their perception of the service providers’ performance that further creates differentiation and competitive advantage, which enhance MO practices and ultimately lead to improvements in the firm’s performance. Implications of the findings, potential limitations of the study, and directions for future research are highlighted.

Social dominance orientation (SDO), a theoretical construct, typically focusing on intergroup perceptions and relations, is one aspect that has been left unexplored and might prove particularly enlightening. The present study investigated SDO among 119 deaf and 49 hearing young adults through a standardized SDO questionnaire. SDO was examined with regard to cultural identities (deaf, hearing, bicultural, and marginal), cochlear implant use, and language orientation (sign language or spoken language). The deaf participants were found to be more egalitarian than hearing individuals overall. Deaf individuals who held the strongest deaf identities, those who were sign language oriented, and not cochlear implant users, were the most egalitarian. © The Author 2017.

    Oriented collagen scaffolds were developed in the form of sheet, mesh and tube by arraying flow-oriented collagen string gels and dehydrating the arrayed gels. The developed collagen scaffolds can be any practical size with any direction of orientation for tissue engineering applications. The birefringence of the collagen scaffolds was quantitatively analyzed by parallel Nicols method. Since native collagen in the human body has orientations such as bone, cartilage, tendon and cornea, and the orientation has a special role for the function of human organs, the developed various types of three-dimensional oriented collagen scaffolds are expected to be useful biomaterials for tissue engineering and regenerative medicines.

  5. Random tensors

    CERN Document Server

    Gurau, Razvan

    2017-01-01

    Written by the creator of the modern theory of random tensors, this book is the first self-contained introductory text to this rapidly developing theory. Starting from notions familiar to the average researcher or PhD student in mathematical or theoretical physics, the book presents in detail the theory and its applications to physics. The recent detections of the Higgs boson at the LHC and gravitational waves at LIGO mark new milestones in Physics confirming long standing predictions of Quantum Field Theory and General Relativity. These two experimental results only reinforce today the need to find an underlying common framework of the two: the elusive theory of Quantum Gravity. Over the past thirty years, several alternatives have been proposed as theories of Quantum Gravity, chief among them String Theory. While these theories are yet to be tested experimentally, key lessons have already been learned. Whatever the theory of Quantum Gravity may be, it must incorporate random geometry in one form or another....

    2010-09-01

    In this pilot study we examined the determinants of recovery orientation among employees and influential stakeholders in a sample of 12 county departments of mental health in California. A two-level hierarchical linear model with random intercepts was estimated. Analyses show that recovery orientation has a U-shaped relationship with the age of staff/influential stakeholders and is negatively related to the difference between the desired level of adhocracy and the current level of adhocracy. Recovery orientation is positively related to the education level of staff/influential stakeholders, satisfying transformational leadership outcomes, and larger mental health budgets per capita. Policy implications are discussed.

    The influence of the substrate on the translational and orientational ordering in sub-monolayer films of passivated multiply-twinned gold clusters has been investigated using high resolution and dark field transmission electron microscopy. Although clear differences were observed in the degree of translational ordering on amorphous carbon and etched silicon substrates, there was no corresponding variation in the crystallographic orientation of the nanocrystal cores. The results demonstrate that the orientation of passivated clusters with multiply-twinned cores is effectively random with respect to both the superlattice and the substrate.

    CERN Multimedia

    2000-01-01

    Object oriented technologies are the corner stone of modern software development. A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

    Stoll, Margareth; Laner, Dietmar, Dr.

    Due to different directives, the growing request for citizen-orientation, improved service quality, effectiveness, efficiency, transparency and reduction of costs, as well as administrative burden public administrations apply increasingly management tools and IT for continual service development and sustainable citizens' satisfaction. Therefore public administrations implement always more standard based management systems, such as quality ISO9001, environmental ISO 14001 or others. Due to this situation we used in different case studies as basis for e-government a the administration adapted, holistic administration management model to analyze stakeholder requirements and to integrate, harmonize and optimize services, processes, data, directives, concepts and forms. In these case studies the developed and consequently implemented holistic administration management model promotes constantly over more years service effectiveness, citizen satisfaction, efficiency, cost reduction, shorter initial training periods for new collaborators, employee involvement for sustainable citizen-oriented service improvement and organizational development.

    Highlights: • Micro-orientation control method for organic polysilane thin films is proposed. • This method utilizes surface modification of graphite using heteroatom doping. • Lying, standing, and random orientations can be freely controlled by this method. • Micro-pattering of a polysilane film with controlled orientations is achieved. - Abstract: Near-edge X-ray absorption fine structure (NEXAFS) spectroscopy is applied to study orientation structures of polydimethylsilane (PDMS) films deposited on heteroatom-doped graphite substrates prepared by ion beam doping. The Si K-edge NEXAFS spectra of PDMS show opposite trends of polarization dependence for non irradiated and N{sub 2}{sup +}-irradiated substrates, and show no polarization dependence for an Ar{sup +}-irradiated substrate. Based on a theoretical interpretation of the NEXAFS spectra via first-principles calculations, we clarify that PDMS films have lying, standing, and random orientations on the non irradiated, N{sub 2}{sup +}-irradiated, and Ar{sup +}-irradiated substrates, respectively. Furthermore, photoemission electron microscopy indicates that the orientation of a PDMS film can be controlled with microstructures on the order of μm by separating irradiated and non irradiated areas on the graphite surface. These results suggest that surface modification of graphite using ion beam doping is useful for micro-orientation control of organic thin films.

  19. Orientational anisotropy in infant vision

    Science.gov (United States)

    Cohen Leehey, S.; Moskowitz-Cook, A.; Brill, S.; Held, R.

    Infants prefer to look at horizontal and vertical gratings rather than at oblique gratings only when they are at or near threshold spatial frequencies, as would be expected if acuity for oblique edges is lower than that for horizontal and vertical edges. That such a bias exists as early as 6 weeks of age suggests that the orientational asymmetry of the visual system depends on endogeneous maturation rather than exposure to a carpentered world.

    2004-02-01

    To investigate abnormalities of orientational contrast sensitivity (CS) and chromatic contrast threshold (CCT) in multiple sclerosis (MS). Case control study. Nine subjects (mean age, 42 +/- 11 years; range, 20-62 years) with MS, an expanded disability status scale of 3 or less, and normal visual acuity (VA) (logarithm of the minimum angle of resolution [logMAR] VA less than.1) in the tested eye were age-matched with 20 controls. Achromatic CS and CCT were measured using static, computer-generated sinusoidal gratings displayed on a high-resolution monitor. The CS and CCT of each subject were determined using a randomized double-staircase reversal algorithm; CS was measured at five spatial frequencies with horizontal orientation and three with vertical orientation; CCT was measured along the red-green and tritan confusion axes. The sensitivity thresholds of subjects were examined in relation to the mean sensitivity of controls for each spatial frequency. Two subjects had loss of horizontal and vertical CS, and three had isolated vertical loss. When compared with the control mean, there were significant reductions in red-green (P =.016) and tritan (P =.016) discrimination thresholds. This study used a computerized psychophysical test designed to minimize many of the test errors associated with earlier studies. It provides confirmatory evidence that MS may be associated with a loss of orientational CS and color vision, in the absence of reduced VA.

    Due to developments of the health market, economic aspects of the health system are more relevant. In this upcoming market the patient is regarded as customer and the doctor as provider of medical services. Studies on customer orientation in the ambulant medicine lag behind this dynamic. An aim of the study is to comprehend the attitudes of the doctors referring to the customer orientation. In a second step the findings are discussed according to statements of health-care paticipants. Developments in role comprehension of doctor and patient are focused to gain results in scientific and practical applications. Guideline-supported, partly narrative interviews with n=9 gynaecologists and n=11 general practitioners in Freiburg/Germany are recorded, transcribed and reviewed in a qualitative analysis. The statements of the doctors show patient satisfaction has an incremental meaning sspecially regarding the sequence of patient relationship and economic management of the doctor's workplace. The doctor's role comprehension meets with a refusal of the role of salesman and the patient as customer. The method of interviews is suitable to gather empirical impressions of the doctors. The control sample is adequate, however a bias due to inhomogeneous thematic affinitiy and local social-demographics might be possible. The customer orientation has become an important factor in doctor-patient relationtships. The relevance of the doctor-patient conversation and the risk of misuse of the patient confidence are mentioned by the doctors. The doctor as paternalistic care provider gives way to the customer-focused service provider. The doctor's necessity of autonomyssss and dependency on patient satisfaction have potential for conflict. Intensive mention of customer orientation in medicine in the media emphasises its importance. Rational handling with the possibilities of individual health markets is a prospective challange. Further research could be established in all aspects of

    Factors associated with students' orientations to nursing This paper presents the results of a study focusing on the factors associated with orientations to nursing. Students' orientations to nursing have not as yet been a focus of nursing research. In some other professions, however, professional orientation has been associated with learning motivation and study performance, and has been seen as a predictor of work satisfaction. In this study, students' orientations to nursing were defined in terms of caring, nursing expertise and life orientation. The hypothesis of whether students' pre-educational experiences of nursing, gender, choice of nursing specialty, problems with nursing studies and intention to stay in nursing were associated with different orientations was tested. The extent to which students were orientated to caring, nursing expertise and their own life was also examined. The orientation to nursing measurement tool, which has been developed on the basis of a qualitative study, was used to collect the data. Nurse teachers collected the data from nursing students (n=184) who were studying in three different nursing programmes in Finland. Non-parametric assessments (Mann-Whitney U-test and Kruskal-Wallis test) of the differences between the students' orientations were carried out. A majority of the students were highly life-orientated, and two-thirds had average nursing expertise or caring orientation scores. The results supported the study hypothesis of an association between students' orientations and their gender, choice of nursing speciality, problems with nursing studies and intention to stay in nursing. However, the hypothesis of an association between students' pre-educational nursing experiences and orientation to nursing was not supported. The contradictions between students' orientation to nursing and the philosophy of nursing underlying the study programme may be a source of motivational problems and dissatisfaction with nursing education

    Orientation Week is a series of events at the beginning of the university year that introduces incoming students to university life. It is also the period of the academic year when students consume more alcohol than at any other time. Recently, we demonstrated that alcohol consumption during Orientation Week was related to alcohol consumption during the academic year. The aim of the present study was to determine whether a brief Ecological Momentary Intervention (EMI) implemented during Orientation Week could reduce alcohol consumption during Orientation Week and throughout the academic year. Participants were 130 freshman-year university students (72 women, 58 men) randomly assigned to either an Ecological Momentary Assessment (EMA) condition or an EMA-EMI condition. In both conditions, participants reported pre-university, Orientation Week, and academic year weekend alcohol consumption. Those in the EMA-EMI condition also received EMI text messages promoting moderation every night during Orientation Week. Although the EMI did not reduce men's drinking, women in the EMA-EMI condition, compared with women in the EMA condition, consumed significantly fewer drinks during Orientation Week, M = 17.1, SD = 13.3, vs. M = 26.4, SD = 22.5, respectively, t(70) = -1.927, p EMIs during Orientation Week.

  11. The impact of interference on short-term memory for visual orientation.

    Rademaker, Rosanne L; Bloem, Ilona M; De Weerd, Peter; Sack, Alexander T

    2015-12-01

    Visual short-term memory serves as an efficient buffer for maintaining no longer directly accessible information. How robust are visual memories against interference? Memory for simple visual features has proven vulnerable to distractors containing conflicting information along the relevant stimulus dimension, leading to the idea that interacting feature-specific channels at an early stage of visual processing support memory for simple visual features. Here we showed that memory for a single randomly orientated grating was susceptible to interference from a to-be-ignored distractor grating presented midway through a 3-s delay period. Memory for the initially presented orientation became noisier when it differed from the distractor orientation, and response distributions were shifted toward the distractor orientation (by ∼3°). Interestingly, when the distractor was rendered task-relevant by making it a second memory target, memory for both retained orientations showed reduced reliability as a function of increased orientation differences between them. However, the degree to which responses to the first grating shifted toward the orientation of the task-relevant second grating was much reduced. Finally, using a dichoptic display, we demonstrated that these systematic biases caused by a consciously perceived distractor disappeared once the distractor was presented outside of participants' awareness. Together, our results show that visual short-term memory for orientation can be systematically biased by interfering information that is consciously perceived. (c) 2015 APA, all rights reserved).

    General causality orientations are motivational styles that are indicative of a person's belief about personal change and their motivation to change. The purpose of the current study was to investigate whether causality orientations were associated with marijuana treatment outcomes in a sample of marijuana-dependent individuals. A total of 74 participants (66% male) were recruited from the Seattle, Washington area and randomly assigned to receive a combination of motivational enhancement and cognitive behavioral therapy or the combination treatment plus additional "check-up" sessions. Follow-up assessments evaluated frequency of use, use-related problems, and marijuana use disorder symptoms through 9months. Causality orientations were relatively stable over time. Posttreatment Autonomy orientations were associated with lower frequency of use and Controlled orientations were associated with a reduction in use, problems, and marijuana use disorder symptoms. Autonomy and Controlled orientations were associated with readiness to change. Results suggest that both autonomous and controlled orientations have implications for response to treatment; perhaps for different reasons. Causality orientations may be a promising avenue of research to predict treatment response and outcome. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This study investigated the relationship between resilience and religious orientation (internal and external) with posttraumatic growth (PTG). This study also examined the impact of marriage and sex variables on growth. Participants were selected based on prescreening of a larger group of students enrolled in the University of Shiraz. Participants were recruited in two stages. Three hundred fifty students were randomly selected in the first stage, and those students who experienced a minimum of one traumatic event within the last five years were selected in the second stage. They completed the Traumatic Life Event Questionnaire (TLEQ), the Posttraumatic Growth Inventory-Iranian version (PTGI-I), and the Religious Orientation Scale (ROS). According to stepwise regression analysis, two subscales of resiliency, novelty seeking and positive future orientation, and a subscale of religious orientation, intrinsic orientation, were related to PTG. In addition, compared to singles, the married subjects experienced greater degree of growth. Personal extrinsic orientation and emotional regulation factor of resilience had a positive and meaningful relationship with PTG, although they were omitted from the regression analysis model. Sex and Socio-Extrinsic religious orientation were not related to PTG. Some subscales of resiliency and religious orientation could predict posttraumatic growth in Iranian subjects, but there were no gender differences. The intrinsic orientation had the greatest significance in predicting posttraumatic growth. The personal extrinsic orientation had a significant positive correlation with post-traumatic growth, no significant correlation was observed between social extrinsic orientation and post-traumatic growth. The openness to experience was an important feature for proper growth of people facing a trauma. Optimistic subjects showed more flexibility in their coping strategies, and therefore had a tendency to adapt themselves to problematic

    Full Text Available In this paper, first, we study random best approximations to random sets, using fixed point techniques, obtaining this way stochastic analogues of earlier deterministic results by Browder-Petryshyn, KyFan and Reich. Then we prove two fixed point theorems for random multifunctions with stochastic domain that satisfy certain tangential conditions. Finally we consider a random differential inclusion with upper semicontinuous orientor field and establish the existence of random solutions.

  2. Asymmetric evolving random networks

    We generalize the Poissonian evolving random graph model of M. Bauer and D. Bernard (2003), to deal with arbitrary degree distributions. The motivation comes from biological networks, which are well-known to exhibit non Poissonian degree distributions. A node is added at each time step and is connected to the rest of the graph by oriented edges emerging from older nodes. This leads to a statistical asymmetry between incoming and outgoing edges. The law for the number of new edges at each time step is fixed but arbitrary. Thermodynamical behavior is expected when this law has a large time limit. Although (by construction) the incoming degree distributions depend on this law, this is not the case for most qualitative features concerning the size distribution of connected components, as long as the law has a finite variance. As the variance grows above 1/4, the average being < 1/2, a giant component emerges, which connects a finite fraction of the vertices. Below this threshold, the distribution of component sizes decreases algebraically with a continuously varying exponent. The transition is of infinite order, in sharp contrast with the case of static graphs. The local-in-time profiles for the components of finite size allow to give a refined description of the system.

    Full Text Available In this paper we present algorithms for measuring local characteristics of random fiber systems. The calculation of the local directions and radii is based on directional distance transforms and evaluation of the inertia moments and axes of the resulting extremities of the centralized, directed chords. The method provides continuous results while minimizing the runtime by using few sampled directions. Furthermore several steps of improvement for the computation of orientation and radius information are presented. The algorithms are evaluated using synthetic data and applied to images of realmicrostructures obtained by computer tomography.

    We asked whether homosexual and heterosexual men and women differ on standard measures of cognitive ability. Subjects were adults recruited for a family study of sexual orientation. They completed the Fy Scale of the California Psychological Inventory, a self-administered measure of psychological "femininity," and were given subtests of the Wechsler Adult Intelligence Scale and the Primary Mental Abilities test which had been previously shown to discriminate between the sexes. We predicted that homosexual subjects would score significantly in the gender-atypical direction on the Fy scale. We also predicted that they would achieve scores on the tests of cognitive abilities significantly in the direction of the other gender. Comparisons were made between homosexual and heterosexual individuals within gender. Also, comparisons were made between heterosexual men and women to see if our results replicate differences typically found between the genders. As predicted, both homosexual men and women were strongly gender-atypical on the Fy scale relative to their heterosexual counterparts. However, neither differed from heterosexuals on any of the measures of cognitive abilities. Heterosexual men did better than women on the Primary Mental Abilities spatial relations test. We conclude that sexual orientation is not related to specific cognitive abilities.

    Oriented immobilization of antibodies on a sensor chip is crucial for enhancing both the sensitivity and antigen-binding capacity of immunosensors. Here, we report a comparative study of the effect of oriented and random antibody immobilization on the binding efficiency by electrochemical impedance spectroscopy (EIS). Oriented immobilization of anti-myoglobin immunoglobulin G (anti-Myo IgG) was achieved by bonding to an Fc receptor of protein G (PrG) on a self-assembled monolayer (SAM), which results in the myoglobin (Myo) binding sites being exposed outside the sensing surface. Random immobilization of anti-Myo IgG was achieved by direct covalent attachment to the SAM surface. Both immobilizations were applied to interdigitated electrodes to enhance the electrochemical signal, and the Myo biosensor performance was then evaluated by a series of EIS measurements. We found that (i) the rate of the normalized charge transfer resistance for the oriented sample was 3 times higher than that for the random sample and (ii) the detection limit was 0.001 ng/mL, which is the lowest recorded detection limit among Myo immunosensors based on EIS. These findings indicate that oriented antibody immobilization is crucial for preparing highly sensitive EIS-based biosensors.

    ZnFe2O4/SiO2/PANI (ZSP) core/shell/shell nanostructured disks are prepared and fabricated into paraffin-bonded ZSP composite rings with random, vertical, and horizontal orientations of the easy magnetization planes of the ZSP disks in the paraffin binder in order to study the effect of directional orientation of the easy magnetization planes on their electromagnetic properties. The easy magnetization planes induced by shape anisotropy and oriented by a magnetic field in the vertically oriented ring result in a general enhancement in permeability of 7-60% in the broad UHF-Ku (0.1-18 GHz) bands, while those in the horizontally oriented ring lead to a significant enhancement of 58-1100% in the low-frequency L and S (1-4 GHz) bands, in comparison with the randomly oriented ring. The observed permeability agrees with the theoretical prediction based on the Landau-Lifshitz-Gilbert equation and the Bruggeman's effective medium theory. The horizontal and vertical arrangements of dipolar polarizations in the vertically and horizontally oriented rings give rise to 3-11% enhancement and weakening in permittivity, respectively, compared to the randomly oriented ring. The enhancement in permeability also improves and broadens the electromagnetic wave absorption in both vertically and horizontally oriented rings, especially in the L and S bands for the horizontally oriented ring.

    Misconceptions about psychiatric wards frequently cause newly admitted mental patients to stay away from these wards despite their need for treatment. Although ward orientation is typically conducted by nurses in an attempt to help patients to adapt to the new environment, it is considered time-consuming, and the method of orientation and the explanations given may vary among different nurses. This situation calls for a more effective and standardized approach to orientating mental patients on their first admission. To this end, a computer-based interactive virtual environment was developed based on a real psychiatric ward by using virtual reality (VR) technologies. It enables the patient to navigate around to gain understanding about the ward through a virtual guided tour. The effectiveness of this VR orientation approach was investigated by a randomized controlled trial with consecutive sampling. Fifty-four Chinese participants were randomly assigned to undergo ward orientation by either using the VR-based approach or reading text-based electronic information sheets about the ward with a computer. Subjective and objective measures were obtained respectively using the Chinese version of the State-Trait Anxiety Inventory questionnaire and the heart-rate variability measurement before and after the intervention. In addition, a test on the level of understanding about the ward was administered at the end of the session. The results showed that the VR orientation approach is helpful in reducing patients' anxiety while also improving their level of understanding about the ward.

    The orientation of sensing molecules on solid phase biosensors has to be optimized to facilitate efficient binding of analytes. Since conventional observation methods (e.g., electron microscopy, atomic force microscopy, time-of-flight secondary ion mass spectrometry) require exaggerated machines and possess insufficient resolution for single molecule analyses, functional assays based on the reactivity to analytes have thus far been used for this optimization. However, it is not clear whether these assays can judge whether sensing molecules are fixed in an oriented-immobilization manner or not. Here, we describe that bio-nanocapsules of about 30 nm diameter, displaying approximately 120 molecules of a tandem form of the immunoglobulin (Ig) G Fc-binding Z domain (ZZ-BNCs), can discriminate between the Fc regions of IgGs fixed in an oriented-immobilization manner and those fixed randomly, thus facilitating the evaluation of the orientation of IgGs in immunosensors. Furthermore, in sandwich immunoassays, ZZ-BNCs can bind specifically to detection-IgGs fixed in an oriented-immobilization manner by antigen-capture IgG complexes, rather than to capture-IgGs fixed randomly onto a solid phase, allowing the simultaneous use of the same IgG as capture- and detection-IgGs. Thus, we demonstrate that ZZ-BNCs are a unique probe for evaluating the orientation of IgGs on a solid phase.

    Full Text Available We studied numerically external field induced memory effects in randomly perturbed nematic liquid crystals. Random anisotropy nematic-type lattice model was used. The impurities imposing orientational disorder were randomly spatially distributed with the concentration p below the percolation threshold. Simulations were carried for finite temperatures, where we varied p, interaction strength between LC molecules, and impurities and external field B. In the {B,T} plane we determined lines separating short range—quasi long range and quasi long range—long range order. Furthermore, crossover regime separating external field and random field dominated regime was estimated. We calculated remanent nematic ordering in samples at B=0 as a function of the previously experienced external field strength B.

    The molecular orientation at the surfaces of poly(9-vinylcarbazole) (PvCz) thin films was studied by angle-resolved ultraviolet photoelectron spectroscopy and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. The observed take-off angle (theta) dependence of photoelectron intensities from top pi band peaks clearly at larger theta than the calculated one for the three-dimensional isotropic random orientation model. The results indicate that there are more pendant groups with large tilt angles than the three-dimensional isotropic random orientation model, which is in good agreement with the result obtained from NEXAFS spectroscopy. The surface electronic states of PvCz may be rather dominated by sigma(C-H) states at the pendant carbazole group than pi states

    In two studies, the authors examined how threat induced by reminders of mortality would moderate the effect of political orientation on moral judgments. In Study 1, university students (n = 113) categorized their political orientation, were randomly assigned to complete a fear of death or public speaking scale, and then completed a moral foundations questionnaire. In Study 2, university students (n = 123) rated their political orientations, were randomly assigned to write about their own death or dental pain, and then completed a moral foundations questionnaire. In both studies, mortality salience intensified the moral differences between liberals and conservatives. These findings were primarily the result of the reactions of liberals, who responded to mortality salience with increased ratings of the fairness/cheating virtue in Study 1 and the care/harm virtue in Study 2. © 2014 The British Psychological Society.

    Full Text Available Over the past 30 years research on Entrepreneurship Orientation (EO has provided valuable information regarding strategy, entrepreneurship and aspects of performance at the firm-level. In the entrepreneurial universe, microenterprises play a very special role in the business context of the economy. However, they have not been relatively present in the EO research. This paper studies the EO-performance relationship in a group of microenterprises in Mexico and includes the Dominant Logic (DL as a variable that moderates this relationship. The results indicate that risk taking, proactiveness and competitive aggressiveness variables from the EO influence the microenterprise performance. In addition, the external DL conceptualization moderates the EO-performance relationship. This paper shows the conclusions of the investigation as well as the limitations and identifies future research methods.

  2. Umbilic Lines in Orientational Order

    Directory of Open Access Journals (Sweden)

    Thomas Machon

    2016-03-01

    Full Text Available Three-dimensional orientational order in systems whose ground states possess nonzero gradients typically exhibits linelike structures or defects: λ lines in cholesterics or Skyrmion tubes in ferromagnets, for example. Here, we show that such lines can be identified as a set of natural geometric singularities in a unit vector field, the generalization of the umbilic points of a surface. We characterize these lines in terms of the natural vector bundles that the order defines and show that they give a way to localize and identify Skyrmion distortions in chiral materials—in particular, that they supply a natural representative of the Poincaré dual of the cocycle describing the topology. Their global structure leads to the definition of a self-linking number and helicity integral which relates the linking of umbilic lines to the Hopf invariant of the texture.

    2010-01-01

    This article revisits the debate about recent American torture practices, particularly the use of discredited anthropological texts to validate long-held Orientalist assumptions about the sexual vulnerability of Muslim males. Such practices are placed in an historical context of older imperial constructions of sexually deviant Muslims as well as of more general forms of gendered and sexual subordination required for war. American torturers intended to produce very particular objects of torture—ones willing and able to confess their 'true' orientation in terms of a binary hetero/homo sexual code established in 19th-century Europe. The torturers had the power to confirm through confession and re-enactment their crude assumptions, irrespective of the actual sexualities of those being tortured, with consequences for the transnational and reactionary politics of sexual identity.

    2014-08-01

    Full Text Available In the recent years, research of special compiler techniques and algorithms for embedded processors broaden the knowledge of how to achieve better compiler performance in irregular processor architectures. However, industrial strength compilers, besides ability to generate efficient code, must also be robust, understandable, maintainable, and extensible. This raises the need for compiler infrastructure that provides means for convenient implementation of embedded processor oriented compiler techniques. Cirrus Logic Coyote 32 DSP is an example that shows how traditional compiler infrastructure is not able to cope with the problem. That is why the new compiler infrastructure was developed for this processor, based on research. in the field of embedded system software tools and experience in development of industrial strength compilers. The new infrastructure is described in this paper. Compiler generated code quality is compared with code generated by the previous compiler for the same processor architecture.

    Irfan Shirazi M.

    2014-07-01

    Full Text Available Fiber orientation is a big challenge in short fiber reinforced composites. Powder injection molding (PIM process has some intrinsic fiber alignment associated with it. During PIM process fibers in skin region of moldings are aligned as these regions experience higher shear flow caused by the mold walls. Fibers in the core region remain randomly aligned as these regions are far from mold walls and experience lesser shear flow. In this study short carbon fiber (CF reinforced copper matrix composite was developed by PIM process. Two copper composite feedstock formulations were prepared having 5 vol% and 10 vol% CFs and a wax based binder system. Fiber orientation was controlled during injection molding by using a modified mold that has a diverging sprue. The sprue creates converging flow when feedstock enters into the mold cavity. Fiber orientation was analysed after molding using FESEM. The orientation of fibers can be controlled by controlling flow of feedstock into the mold.

    This study examined the validity of the Sport Orientation Questionnaire (Competitiveness: 13 items, Win Orientation: 6 items, and Goal Orientation: 6 items) in a sample of 195 wheelchair basketball athletes from the USA. Following evidence for sample-specific validity, the measurement model that underlies the questionnaire was examined. A short-form with 15 items for three factors of Competitiveness (7 items), Win Orientation (5 items) and Goal Orientation (3 items) fit the data (X2/df ratio=2.21, NNFI=.892, CFI=.991, RCFI=.935, SRMR=.058, RMSEA=.071). To evaluate the findings further, we cross-validated the short-form by sex. Structural equation modeling indicated there were similar measurement properties and factor structures for the men and women, indicating similar conceptualization of sport orientations. Meaningful comparisons across sex may be undertaken, since both men and women who are wheelchair basketball athletes perceive the three short-form SOQ factors similarly.

    The study examines gender and psychological sexual identity as alternative bases for the development of hemispheric orientation. Hypotheses anticipated that females place greater reliance upon right hemisphere functions, such as imagery and emotion, whereas males place more emphasis upon left hemisphere functions, such as logical reasoning. This was extended to an examination of the roles of masculinity and femininity within genders upon hemispheric orientation. With a sample of 219 male and 221 female adults, it was found that the male-left hemisphere orientation/female-right hemisphere orientation dichotomy was supported in part. However, this relationship appears to be moderated by a second dimension: females appear more internally oriented, males more externally oriented.

  9. Perceptions of Sexual Orientation From Minimal Cues.

    Rule, Nicholas O

    2017-01-01

    People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

  10. Orientation, distance, regulation and function of neighbouring genes

    2009-01-01

    Full Text Available Abstract The sequencing of the human genome has allowed us to observe globally and in detail the arrangement of genes along the chromosomes. There are multiple lines of evidence that this arrangement is not random, both in terms of intergenic distances and orientation of neighbouring genes. We have undertaken a systematic evaluation of the spatial distribution and orientation of known genes across the human genome. We used genome-level information, including phylogenetic conservation, single nucleotide polymorphism density and correlation of gene expression to assess the importance of this distribution. In addition to confirming and extending known properties of the genome, such as the significance of gene deserts and the importance of 'head to head' orientation of gene pairs in proximity, we provide significant new observations that include a smaller average size for intervals separating the 3' ends of neighbouring genes, a correlation of gene expression across tissues for genes as far as 100 kilobases apart and signatures of increasing positive selection with decreasing interval size surprisingly relaxing for intervals smaller than ~500 base pairs. Further, we provide extensive graphical representations of the genome-wide data to allow for observations and comparisons beyond what we address.

    Sexual orientation may be defined as the sustained erotic attraction to members of one's own gender, the opposite gender, or both--homosexual, heterosexual, or bisexual, respectively. Interest in sexual orientation is as old as the science of psychology, yet many fundamental issues remain unresolved. This article reviews research in the development and psychopathology of sexual orientation as well as the results of family and twin studies. Research in genetic linkage, sex hormones, and brain differences also is discussed.

    Proverbio, Alice Mado; Esposito, Paola; Zani, Alberto

    2002-02-01

    The aim of the present study was to investigate the neural mechanisms of stimulus orientation selection in humans by recording event-related potentials (ERPs) of the brain with a 32-channel montage. Stimuli were isoluminant black-and-white gratings (3 cpd) having an orientation of 50, 70, 90, 110 and 130, randomly presented in the foveal portion (2 of visual angle) of the central visual field. The task consisted in selectively attending and responding to one of the five grating orientations, while ignoring the others. ERP results showed that orientation selection affected neural processing starting already at an early post-stimulus latency. The P1 component (80-140 ms) measured at temporal area, which might well be reflecting the activity of the ventral stream (i.e. 'WHAT' system) of the visual pathways, showed an enhanced amplitude for target orientations. These effects increased with progressive neural processing over time as reflected by selection negativity (SN) and P300 components. In addition, both reaction times (RTs) and ERPs showed a strong 'oblique' effect, very probably reflecting the perceptual predominance of orthogonal versus oblique stimulus orientation in the human visual system: RTs were much faster, and SN and P300 components much larger, to gratings presented vertically than in other orientations.

    1998-04-01

    We present an overview of behavioral genetics research on homosexual and heterosexual orientation. Family, twin, and adoptee studies indicate that homosexuality and thus heterosexuality run in families. Sibling, twin, and adoptee concordance rates are compatible with the hypothesis that genes account for at least half of the variance in sexual orientation. We note observations of homosexual behavior in animal species, but the analogy to human sexual orientation is unclear. We discuss the reproductive disadvantage of a homosexual orientation and present possible mechanisms that could maintain a balanced polymorphism in human populations.

  19. RELATIVE ORIENTATION IN LOW ALTITUDE PHOTOGRAMMETRY SURVEY

    Directory of Open Access Journals (Sweden)

    J. Wang

    2012-07-01

    Full Text Available Relative orientation is always considered as a key technique, not only in traditional photogrammetry, but also in low altitude photogrammetry. Low altitude images are mainly obtained by general digital cameras on UAV, they have characteristics of small format, large tilt angle and high-overlap in sequence. These distinctions from traditional images urgently call for a new reliable way to recover the relative pose between two adjacent images. For example, better initial values of relative orientation elements are required in the iteration process due to the large roll angle and yaw angle. Also, a more stable and efficient adjustment method should be proposed for the high-overlap images. In this paper, the Direct (D relative orientation method is firstly used to get coarse values of the relative orientation parameters, then the Conventional (C relative orientation process is implemented, using the coarse values as initial values in the first iterative calculation. And RANSAC (R algorithm is finally applied in locating and extracting gross errors in relative orientation. The three steps above form our execution—DCR—to solve relative orientation problem in low altitude photogrammetry. Practical images have been used later to test the DCR method on accuracy and precision of the relative orientation parameters. Our experimental results show that the proposed approach is feasible and can achieve more reliable relative orientation results than the conventional approach.

    Multiphoton orientational wave packets induced by short resonant polarized laser pulses in a rotationally-frozen interacting molecule contain relevant information. The entanglement of the orbital, rotational and orientational degrees of freedom shows a strong dependence on the polarization state of the absorbed photons and the space orientation of the interacting molecule and enables one to assign the orbital state of the excited molecular electron, to measure the space orientation of the interacting molecule from the orientational recurrences, to relate the measured temporal widths to the angular momentum photon state and the coherence of the laser pulse, to obtain information on the ground rotational state, or to measure the effective temperature of an isotropic molecular assembly. The space orientation of a small number of independent molecules can be distinguished from their distinct orientational dependence in the formation of the individual orientational wave packets.

    Chitosan has long been known as a biocompatible and biodegradable material suitable for tissue engineering applications. Unfortunately, conventional chitosan solutions cannot be used for electrospinning due to their high conductivity, viscosity and surface tension. We have developed a method to produce clear chitosan solutions with conductivities, surface tension and viscosities that facilitate their processing into micron and submicron fibers via electrospinning. Acetic acid, carbon dioxide and organic solvents are key ingredients in preparing the chitosan solutions. Oriented and non oriented chitosan fibers were produced with the ultimate goal of designing a suitable tissue engineering scaffold. Circularly oriented, continuous, and aligned nanofibers were produced via this technique in the form of a thin membrane or fibrous "mat". Chitosan fiber diameters ranged from 5 micrometers down to 100 nanometers. The structure and mechanical properties of oriented and randomly aligned chitosan fiber deposits could potentially be exploited for cartilage tissue engineering. Ultrafine fibers of starch acetate (SA) also were prepared by the electrospinning process. In this study, solvent mixtures based on DMF, DMSO, pyrindine, acetic acid, acetone, THF, DMC, chloroform were used. A two-solvent formulation was used to study the effect of viscosity, surface tension, and conductivity to the fiber diameter. Also, water and ethanol were used to decrease the boiling point of the solvent, and to make bundled fibers. Several techniques such as scanning electron microscopy, conductmetry, viscometry, and tensiometry were used in this study. The results showed that the combined effects of viscosity, surface tension, and conductivity are of great importance in controlling the diameter of the fibers. We were able to produce SA fibers that was less than 40 nm in diameter. The dependence of fiber diameter on flow-rate, electric field and solvents also was investigated. A rotating disk and a

  5. Trunk orientation, stability and quadrupedalism

    Full Text Available Interesting cases of human quadrupedalism described by Uner Tan and colleagues (2005-2012 have attracted the attention of geneticists, neurologists and anthropologists. Since his first publications in 2005, the main attention has focused on the genetic aspects of disorders that lead to quadrupedalism within an evolutionary framework. In recent years this area has undergone a convincing critique (Downey 2010 and ended with a call "... to move in a different direction … away from thinking solely in terms of genetic abnormality and evolutionary atavism". We consider quadrupedalism as a ‘natural experiment’ that may contribute to our knowledge of the physiological mechanisms underlying our balance system and our tendency toward normal (upright posture. Bipedalism necessitates a number of characteristics that distinguish us from our ancestors and present-day mammals, including: size and shape of the bones of the foot, structure of the axial and proximal musculature, and the orientation of the human body and head. In this review we address the results of experimental studies on the mechanisms that stabilize the body in healthy people, as well as how these mechanisms may be disturbed in various forms of clinical pathology. These disturbances are related primarily to automatic rather than voluntary control of posture and suggest that human quadrupedalism is a behavior that can result from adaptive processes triggered by disorders in postural tone and environmental cues. These results will serve as a starting point for comparing and contrasting bi- and quadrupedalism.

  6. Plenoptic background oriented schlieren imaging

    2017-09-01

    The combination of the background oriented schlieren (BOS) technique with the unique imaging capabilities of a plenoptic camera, termed plenoptic BOS, is introduced as a new addition to the family of schlieren techniques. Compared to conventional single camera BOS, plenoptic BOS is capable of sampling multiple lines-of-sight simultaneously. Displacements from each line-of-sight are collectively used to build a four-dimensional displacement field, which is a vector function structured similarly to the original light field captured in a raw plenoptic image. The displacement field is used to render focused BOS images, which qualitatively are narrow depth of field slices of the density gradient field. Unlike focused schlieren methods that require manually changing the focal plane during data collection, plenoptic BOS synthetically changes the focal plane position during post-processing, such that all focal planes are captured in a single snapshot. Through two different experiments, this work demonstrates that plenoptic BOS is capable of isolating narrow depth of field features, qualitatively inferring depth, and quantitatively estimating the location of disturbances in 3D space. Such results motivate future work to transition this single-camera technique towards quantitative reconstructions of 3D density fields.

    1988-01-01

    The paper focuses on studying the cognitive determinants of obesity within the framework of the cognitive orientation (CO) theory. This theory assumes that cognitive contents and processes guide behavior, and specifies procedures for predicting and changing behaviors. The subjects were 64 obese and 64 nonobese women matched in age, height and other demographic variables. They were administered the MMPI and a CO questionnaire of obesity which assessed beliefs of four types (about goals, rules and norms, self and general beliefs) concerning 20 themes found to represent the meanings of food, eating and obesity. The results showed that the groups did not differ and had no elevated scores on any of the MMPI scales. The obese had higher scores than the controls on each of the belief types, an overall belief index, 19 themes and a conflict propensity measure. A discriminant analysis showed 88.3 percent correct identifications on the basis of the beliefs. Discussion focused on the role of conflicts and the different themes in obesity and on outlining the elements of a CO model of obesity with therapeutic implications.

    Science.gov (United States)

    Stensrud, R; Arrington, B

    1988-03-01

    Organizations can be oriented toward marketing from a production, product, sales, or marketing perspective. Strategies, structures, and cultures, which reflect a company's basic orientation, must be integrated to ensure that marketing efforts communicate a clear corporate position. In a study of 31 hospitals, the Center for Health Services Education Research, St. Louis University, found that no hospital's organization fit neatly into a single category. For example, a hospital may have some service lines that were marketing oriented while other lines were production oriented. The majority of hospitals, however, were product oriented, focusing on productivity and financial performance rather than on market factors. The most effective sales orientation was observed in the for-profits. Their selling efforts, however, tended to be internally focused, with product development activities divorced from the planning and marketing functions. Only the for-profit hospitals showed the beginning of a marketing orientation. Developing a marketing orientation, especially in line divisions, requires a careful, well-orchestrated effort and the presence of several key factors: Access to capital and an emphasis on long-range planning and strategic spending The availability of hospital-specific market research. Key distribution channels. Talented middle managers. Up-to-date systems and structures equipped to serve new values and strategies. Leaders capable of communicating to the organization a vision of its role in the community.

    Full Text Available The aim of the article was to find nexus between brand orientation and financial performance in companies doing business in Serbia. We surveyed general managers, marketing managers, and brand managers in order to examine their views on the brand orientation dimensions of their companies. We matched the survey results with financial performance of those companies (EBITDA margin in order to find linkages between these variables. We got expected results in the sense that strong brand orientation and weaker brand barriers lead to better financial performance. Overall brand orientation is significantly positively correlated with EBITDA margin, and brand barriers are significantly negatively correlated with that measure. We analysed the brand orientation and brand barriers between groups of companies classified according to their size, internationalization, origin of company ownership, origin of brand, specific business area of key brands and type of goods sold. Interestingly, there are undoubted differences in brand orientation and brand barriers only between foreign and domestic companies. These differences could be seen as one of the main reasons of differences between their EBITDA margins. Also, we saw some differences in brand orientation in case of companies with international brands in relation to companies with domestic brands, but those differences are fewer and smaller. We did not find any other statistically significant difference. The significance of the paper is in emphasizing that development of brand orientation of domestic companies could lead to improvement of their profitability and competitiveness.

  19. Asymmetries in perception of 3D orientation.

    Directory of Open Access Journals (Sweden)

    Allan C Dobbins

    2010-03-01

    Full Text Available Visual scene interpretation depends on assumptions based on the statistical regularities of the world. People have some preference for seeing ambiguously oriented objects (Necker cubes as if tilted down or viewed from above. This bias is a near certainty in the first instant (approximately 1 s of viewing and declines over the course of many seconds. In addition, we found that there is modulation of perceived orientation that varies with position--for example objects on the left are more likely to be interpreted as viewed from the right. Therefore there is both a viewed-from-above prior and a scene position-dependent modulation of perceived 3-D orientation. These results are consistent with the idea that ambiguously oriented objects are initially assigned an orientation consistent with our experience of an asymmetric world in which objects most probably sit on surfaces below eye level.

  20. Aggregated Recommendation through Random Forests

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Aggregated recommendation refers to the process of suggesting one kind of items to a group of users. Compared to user-oriented or item-oriented approaches, it is more general and, therefore, more appropriate for cold-start recommendation. In this paper, we propose a random forest approach to create aggregated recommender systems. The approach is used to predict the rating of a group of users to a kind of items. In the preprocessing stage, we merge user, item, and rating information to construct an aggregated decision table, where rating information serves as the decision attribute. We also model the data conversion process corresponding to the new user, new item, and both new problems. In the training stage, a forest is built for the aggregated training set, where each leaf is assigned a distribution of discrete rating. In the testing stage, we present four predicting approaches to compute evaluation values based on the distribution of each tree. Experiments results on the well-known MovieLens dataset show that the aggregated approach maintains an acceptable level of accuracy.

  1. Nanofiber Orientation and Surface Functionalization Modulate Human Mesenchymal Stem Cell Behavior In Vitro

    Electrospun nanofiber meshes have emerged as a new generation of scaffold membranes possessing a number of features suitable for tissue regeneration. One of these features is the flexibility to modify their structure and composition to orchestrate specific cellular responses. In this study, we investigated the effects of nanofiber orientation and surface functionalization on human mesenchymal stem cell (hMSC) migration and osteogenic differentiation. We used an in vitro model to examine hMSC migration into a cell-free zone on nanofiber meshes and mitomycin C treatment to assess the contribution of proliferation to the observed migration. Poly (ɛ-caprolactone) meshes with oriented topography were created by electrospinning aligned nanofibers on a rotating mandrel, while randomly oriented controls were collected on a stationary collector. Both aligned and random meshes were coated with a triple-helical, type I collagen-mimetic peptide, containing the glycine-phenylalanine-hydroxyproline-glycine-glutamate-arginine (GFOGER) motif. Our results indicate that nanofiber GFOGER peptide functionalization and orientation modulate cellular behavior, individually, and in combination. GFOGER significantly enhanced the migration, proliferation, and osteogenic differentiation of hMSCs on nanofiber meshes. Aligned nanofiber meshes displayed increased cell migration along the direction of fiber orientation compared to random meshes; however, fiber alignment did not influence osteogenic differentiation. Compared to each other, GFOGER coating resulted in a higher proliferation-driven cell migration, whereas fiber orientation appeared to generate a larger direct migratory effect. This study demonstrates that peptide surface modification and topographical cues associated with fiber alignment can be used to direct cellular behavior on nanofiber mesh scaffolds, which may be exploited for tissue regeneration.

    In this paper, Pb(Zr0.52Ti0.48)O3 (PZT) thin films with different preferred orientation were prepared on platinized silicon substrates by a modified sol-gel method. Our results indicate that the polarization switching current in PZT thin films is dependent on preferred orientation and poling temperature. In our measurements, (111)-oriented PZT has a larger polarization switching current than randomly oriented PZT, and with the increase of the degree of (111) preferred orientation and the poling temperature, the polarization switching current gradually increase. Considering the contact of PZT thin film with electrodes, the space-charged limited conduction (SCLC) combined with domain switching mechanism may be responsible for such phenomena. By analyzing the conduction data, we found the interface-limited Schottky emission (ES) and bulk-limited Poole-Frenkel hopping (PF) are not suitable for our samples.

    Polar-axis-oriented CaBi4Ti4O15 (CBTi144) films were fabricated on Pt foils using a complex metal alkoxide solution. The 500-nm-thick film showed the columnar structure and consisted of well-developed grains. The a/b-axis orientation of the ferroelectric films is considered to be associated with the preferred orientation of Pt foil. The film showed good ferro- and piezoelectric properties. The Pr and Ec were 25 μC/cm2 and 306 kV/cm, respectively, at an applied voltage of 115 V. The d33 was characterized as 30 pm/V by piezoresponse force microscopy. The values were twice as large as those of the CBTi144 thin film with random orientation. The polar-axis-oriented CBTi144 films would open up possibilities for devices as Pb-free piezoelectric materials.

    Full Text Available High magnetic field was applied to fabricate novel lead-free piezoelectric ceramics with a textured structure. A compact of crystallographically oriented grains was prepared by dry forming in a high magnetic field from a mixed slurry of bismuth titanate and barium titanate powders. Bismuth titanate particles with a size of about 1 μ m were used as the host material. In the forming process, the slurry was poured into a mold and set in a magnetic field of 10 T until completely dried. Bismuth titanate particles were highly oriented in the slurry under the magnetic field. The dried powder compact consisted of highly oriented bismuth titanate particles and randomly oriented barium titanate particles. Barium bismuth titanate ceramics with a- and b-axis orientations were successfully produced from the dried compact by sintering at temperatures above 1100 ° C.

    In this work, we consider the random broadcast time on random geometric graphs (RGGs). The classic random broadcast model, also known as push algorithm, is defined as: starting with one informed node, in each succeeding round every informed node chooses one of its neighbors uniformly at random and informs it. We consider the random broadcast time on RGGs, when with high probability: (i) RGG is connected, (ii) when there exists the giant component in RGG. We show that the random broadcast time is bounded by {Omicron}({radical} n + diam(component)), where diam(component) is a diameter of the entire graph, or the giant component, for the regimes (i), or (ii), respectively. In other words, for both regimes, we derive the broadcast time to be {Theta}(diam(G)), which is asymptotically optimal.

    There are few data sources on the prevalence of same-sex sexual orientation in England.We aimed to measure the prevalence of same-sex orientation and behavior in the English general population and assess the impact of enquiry format on reporting. The Adult Psychiatric Morbidity Survey 2007 used a multi-stage, stratified probability-sampling design (n=7,403). Two questions addressed sexual orientation and sexual partnership and each had two versions. Version A of the sexual orientation question used "homosexual." Version B used "gay or lesbian." Version A of the sexual partnership question required participants who had male and female partners to say which was predominant, while Version B had a midpoint response option: "about equally with men and women." Participants were randomized between versions. Overall, 5.3% of men and 5.6%of women reported they were not entirely heterosexual. The question using "gay or lesbian" elicited higher (though not statistically significant) reporting of non-heterosexual orientation than the question using "homosexual." A significantly larger proportion of men and women (96.0 and 96.1%) reported entirely heterosexual partnerships in response to Version A of the partnership question than in response to Version B (94.0 and 92.9%) where Version B asked specifically about "kissing, touching, intercourse, or any other form of sex." These figures constitute the first national prevalence data on combined sexual orientation and sexual behavior in England, based on a random probability sample of the general population. They demonstrate that people are willing to report their sexual orientation in survey research, but reporting is sensitive to question wording.

    Given a DFA we consider the random walk that starts at the initial state and at each time step moves to a new state by taking a random transition from the current state. This paper shows that for typical DFA this random walk induces an ergodic Markov chain. The notion of typical DFA is formalized by showing that ergodicity holds with high probability when a DFA is sampled uniformly at random from the set of all automata with a fixed number of states. We also show the same result applies to DF...

    In the context of a survey, an experiment examined how egoistic, altruistic, and biospheric framing of consequences influence stated willingness to pay (SWTP) for eco-labeled electricity. The results for a random sample of 476 Swedish residents showed that SWTP decreases linearly with size of the surcharge for eco-labeled electricity, that SWPT is higher for biospheric framing than for altruistic and egoistic framing, and that SWPT does not differ for altruistic and egoistic framing. A higher SWPT is also observed for individuals with a self-transcendence value orientation than for individuals with a self-enhancement value orientation.

    2007-08-01

    We propose a novel random fractional Fourier transform by randomizing the transform kernel function of the conventional fractional Fourier transform. The random fractional Fourier transform inherits the excellent mathematical properties from the fractional Fourier transform and can be easily implemented in optics. As a primary application the random fractional Fourier transform can be directly used in optical image encryption and decryption. The double phase encoding image encryption schemes can thus be modeled with cascaded random fractional Fourier transformers.

    There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

  13. Orientation aspects of growth during recrystallization

    1997-04-01

    Recrystallization of heavily cold rolled aluminium and copper is studied with the aim of achieving information about effects of crystallography orientation on the growth process. The potentials of several experimental techniques are analysed, and a method well suited for characterizing growth rates of grains with different orientations is developed. This method, which is referred to as the extended Cahn-Hagel method, is used for growth rate determinations in aluminium and copper deformed and annealed under five different conditions. In all the investigated cases, preferential growth of cube oriented grains is observed. Recrystallization models, which simulates the orientational as well as microstructural development, are described. selected models are applied for studies of recrystallization in aluminium and copper under specific deformation and annealing conditions as well as for more general studies of the effects of orientation dependent growth rates on the recrystallization microstructure and texture. Finally, reasons for the observed orientation dependent growth rates are discussed. A new mechanism, orientation pinning, is suggested and it is shown that this mechanism is necessary for the understanding of experimental results. (au) 4 tabs., 41 ills., 153 refs.

  14. Partial wave analysis of oriented collisions

    Harris, A. L.; Amami, S.; Saxton, T.; Madison, D. H.

    2018-01-01

    We present fully differential cross sections (FDCSs) for two collision processes with oriented atoms. The first collision is electron-impact ionization of oriented Mg (3p), and the second collision is electron-impact excitation-ionization (EI) of helium with an oriented final state He+(2p0) ion. Surprisingly, the theoretical functional form of the FDCS is the same for both processes, despite the fact that the only physical similarity is an oriented excited state in both processes. We present FDCS as a function of orientation angle and ejected electron angle for both ionization of oriented Mg(3p) and EI of helium in order to explore possible physical similarities between the two processes. We examine the contributions to the FDCS of individual partial waves of the ionized electron and projectile. For the ionization of oriented Mg, we show that the FDCS are dominated by larger partial waves of the ejected electron, with the dominant partial waves having a dependence on scattering angle and outgoing electron energy sharing. For the EI process, the FDCS is dominated by the L = 2 partial wave, independent of scattering angle or energy sharing. Also, for EI it is possible to have angular momentum transferred from either the target helium atom or the incident projectile.

    2016-09-01

    Full Text Available Objective: The objective of this paper is to identify differences between measurement of organisational entrepreneurship in for-profit and non-profit context and to propose the measures aligned to non-profit organisations. The main research question is whether the scales designed to measure entrepreneurial orientation can be used in non-profit organisations and under which conditions. Research Design & Methods: Research methodology is based on review of research tools and measurement scales related to organisational entrepreneurship and comparison of for-profit and non-profit organisations, as well as their characteristics in the context of entrepreneurial orientation. Findings: Entrepreneurial orientation can be measured in non-profit organisations using existing scales that have been designed for business organisations, however they have to be modified, mostly in the dimension of competitive aggressiveness and autonomy. Additionally, the scale should be enriched with items related to cooperation with other organisations. Implications & Recommendations: It is necessary to develop methods and tools that enable the measurement of entrepreneurial orientation in non-profit organisation as well as comparative research on entrepreneurial orientation in for-profit and non-profit organisations. Contribution & Value Added: The originality of this work lies in studying some aspects of entrepreneurial orientation, that apply to the social context. Some suggestions were formulated relating to the utilisation of entrepreneurial orientation scales (originally designed for business enterprises in non-profit organisations.

  16. Physiological and biomechanical aspects of orienteering.

    Creagh, U; Reilly, T

    1997-12-01

    Orienteering is an endurance running event which differs from other running sports both in its cognitive element and in the type of terrain encountered. The demands of overcoming this terrain are not manifest in significant differences between orienteers and road runners in somatotype, though elite female orienteers have consistently been shown to have higher levels of adiposity (> 19%) than elite road runners. High aerobic power in orienteers (up to 63 and 76 ml/kg/min in women and men, respectively) is coupled with lower anaerobic performance. While leg strength is generally not high when compared with other athletic specialties, female orienteers have relatively good leg flexion strength. The energy cost of running is greatly increased in rough terrain. Oxygen cost was 26% higher while running in a forest when compared with road running. Biomechanical differences in stride pattern contribute towards this increased demand. Despite the high energy demands during competition, orienteers pace themselves such that their mean heart rate remains within the range of 167 to 172 beats/min, despite large fluctuations. The rough terrain encountered in orienteering results not only in a high energy cost but also in a higher incidence of sport-specific injuries, particularly to the ankle. Minor injuries such as cuts and bruises are common during competition.

This was the CERN club’s first successful participation in the World Cup, cementing its reputation as a fixture in the international orienteering world. Orienteering is not your typical Swiss pastime. Developed in Scandinavia, the sport has been gaining popularity internationally. “...

  18. Cognitive representation of orientation: a case study.

    Valtonen, Jussi; Dilks, Daniel D; McCloskey, Michael

    2008-10-01

    Although object orientation in the human brain has been discussed extensively in the literature, the nature of the underlying cognitive representation(s) remains uncertain. We investigated orientation perception in BC, a patient with bilateral occipital and parietal damage from a herpes encephalitis infection. Our results show that in addition to general inaccuracy in discriminating and reproducing line orientations, her errors take the form of left-right mirror reflections across a vertical coordinate axis. We propose that in BC, the cognitive impairment is in failing to represent the direction of tilt for line orientations. Our results suggest that there exists a level of representation in the human brain at which line orientations are represented compositionally, such that the direction of a line orientation's tilt from a vertical mental reference meridian is coded independently of the magnitude of its angular displacement. Reflection errors across a vertical axis were observed both in visual and tactile line orientation tasks, demonstrating that these errors arise at a supra-modal level of representation not restricted to vision, or, alternatively, that visual-like representations are being constructed from the tactile input.

    Orientation and mobility training aims to facilitate independent functioning and participation in the community of people with low vision. (1) To gain insight into current practice regarding orientation and mobility training, and (2) to develop a theory-driven standardized version of this training to teach people with low vision how to orientate and be safe in terms of mobility. STUDY OF CURRENT PRACTICE: Insight into current practice and its strengths and weaknesses was obtained via reviewing the literature, observing orientation and mobility training sessions (n = 5) and interviewing Dutch mobility trainers (n = 18). Current practice was mainly characterized by an individual, face-to-face orientation and mobility training session concerning three components: crystallizing client's needs, providing information and training skills. A weakness was the lack of a (structured) protocol based on evidence or theory. NEW THEORY-DRIVEN TRAINING: A new training protocol comprising two face-to-face sessions and one telephone follow-up was developed. Its content is partly based on the components of current practice, yet techniques from theoretical frameworks (e.g. social-cognitive theory and self-management) are incorporated. A standardized, tailor-made orientation and mobility training for using the identification cane is available. The new theory-driven standardized training is generally applicable for teaching the use of every low-vision device. Its acceptability and effectiveness are currently being evaluated in a randomized controlled trial.

  20. Preferred orientation of ettringite in concrete fractures

    2009-05-15

    Sulfate attack and the accompanying crystallization of fibrous ettringite [Ca6Al2(OH)12(SO4) 3·26H2O] cause cracking and loss of strength in concrete structures. Hard synchrotron X-ray microdiffraction is used to quantify the orientation distribution of ettringite crystals. Diffraction images are analyzed using the Rietveld method to obtain information on textures. The analysis reveals that the c axes of the trigonal crystallites are preferentially oriented perpendicular to the fracture surfaces. By averaging single-crystal elastic properties over the orientation distribution, it is possible to estimate the elastic anisotropy of ettringite aggregates. © 2009 International Union of Crystallography.

  1. An outline of object-oriented philosophy.

    Harman, Graham

    2013-01-01

    This article summarises the principles of object-oriented philosophy and explains its similarities with, and differences from, the outlook of the natural sciences. Like science, the object-oriented position avoids the notion (quite common in philosophy) that the human-world relation is the ground of all others, such that scientific statements about the world would only be statements about the world as it is for humans. But unlike science, object-oriented metaphysics treats artificial, social, and fictional entities in the same way as natural ones, and also holds that the world can only be known allusively rather than directly.

    Full Text Available This exploratory research examines the relationship between food entrepreneur sustainable orientation, mindset and firm sustainable practices in a mixed methods format. In particular we seek to address if entrepreneur behavior and firm practices are congruent with founding entrepreneur espoused support of sustainability. Our survey findings with thirty specialty food entrepreneurs suggest tenuous empirical support for the relationship of entrepreneur sustainable orientation, mindset and firm sustainable practices. However our qualitative results indicate positive relationships between sustainable orientation, mindset and practices. Evidence from this work highlights the critical role of founding entrepreneurs for successful implementation of sustainability along its multiple fronts including profitability.

    Local structure, e.g., local binary pattern (LBP), is widely used in texture classification. However, LBP is too sensitive to disturbance. In this paper, we introduce a novel structure for texture classification. Researches on cognitive neuroscience indicate that the primary visual cortex presents remarkable orientation selectivity for visual information extraction. Inspired by this, we investigate the orientation similarities among neighbor pixels, and propose an orientation selectivity based pattern for local structure description. Experimental results on texture classification demonstrate that the proposed structure descriptor is quite robust to disturbance.

    During its colonization of Korea, the Japanese Empire used the Western medicine as a tool for advertising its advanced culture. However, the medical workforce available in Korea was insufficient. The Rule for Uisaeng (Oriental medicine practitioner) was an ordinance decreed in 1913 with a purpose of supplementing the medical workforce. As the Oriental medicine practitioners became official medical workforce, the Japanese Empire could mobilize them in a hygienic administration such as prevention of epidemics. The Uisaengs also tried to adapt themselves to the colonial environment by studying Western medicines. However, the distrust of the Japanese Empire in Oriental medicine continued until 1920s. Manchurian Incident in 1931 brought a change. As the relationship with China aggravated, the provision of medical herb became unstable and the Japanese Empire began to encourage using Oriental medical herb following the Movement for Improving Rural Region Economy. An attempt of the Japanese Empire to utilize the medical herb resulted in a plan to make the Oriental medical herb officinal. The goal was to organize and standardize the Oriental medical herb through a research by the Medical Herb Investigation Committee. However, the medical herb on the table was the one verified by the Western medicine. That is, it was not a traditional medical herb that uses the original theory of Oriental medicine. There was a minority opinion arguing that they should study the Oriental medicine itself. However, that argument was also based on the theory and principles of the Western medicine. Even though an attempt to make full use of Uisaengs expanded as the war continued, the major medical workforce that the Japanese Empire relied on was those trained in Western medicine. In other words, the Japanese Empire did not give a full credit to the Oriental medicine during the colonial era. During the colonization, Japanese Empire used Oriental medicine under the nominal reason of lack of medical

    In the threat of global warming, the transformation from CO2 to stable carbonate minerals is significant to geological CO2 sequestration in the long term.Previous efforts have found that when carbonate minerals nucleate on some mineral substrates ,the time of carbon capture can be shorted .Many efforts have been focused on the dynamics when carbonate minerals nucleate on mineral substrates, but few have studied the orientation of carbonate minerals on mineral substrates. In our experiment, we mainly focused on the orientation of calcite on mineral substrates.We mixed NaHCO3 and CaCl2 to nucleate when mineral substrates were added and a multi-parameter analyzer was used to monitor in real time to determine the induction time for nucleation. On the basis of classical nucleation theory, we got a brand new formula to decide the orientation of calcite on mineral substrates. lntind=(2-cosθ+cos3θ)*16πγ3vm2(12*(kBT)3*(lnS)2)+ln(1/N0v)+ ΔEa/(kBT)where θ is the angle between the substrate and the nuclei, tind is the induction time for nucleation, γ is he average surface free energy, N0 is the total number of particles per unit volume of solution, ΔEa is the activation energy for molecular motion across the embryo-matrix interface, S is the supersaturation index ,kB is the Boltzmann constant. Using the new formula above , when biotite was used as substrate mineral ,we found that the angle between the biotite and the nuclei was 119°. Angle measured on SEM images also supported our conclusion above. Combined with SEM and Debye ring analysed by Rigaku 2D data processing software, we only found one point of (006) in Debye ring, unlike (104)(many points in one ring and it meant that the orientation of (104) is random ). That meant (001) of calcite was first formed on biotite (001). In that case we inferred that 119° was formed by (001) of botite and (012) of calcite for the intersection angle of (001) and (012) was 120°. Future research will focus on the orientation of

    Diffusion processes in porous materials are often modeled as random walks on fractals. In order to capture the randomness of the materials random fractals are employed, which no longer show the deterministic self-similarity of regular fractals. Finding a continuum differential equation describing the diffusion on such fractals has been a long-standing goal, and we address the question of whether the concepts developed for regular fractals are still applicable. We use the random Koch curve as a convenient example as it provides certain technical advantages by its separation of time and space features. While some of the concepts developed for regular fractals can be used unaltered, others have to be modified. Based on the concept of fibers, we introduce ensemble-averaged density functions which produce a differentiable estimate of probability explicitly and compare it to random walk data.

  10. Were Greek temples oriented towards aurorae?

    Liritzis, Ioannis; Vassiliou, Helen

    2006-02-01

    Two ancient Greek temples of Apollo at Bassae (Phigaleia, western Peloponnese, Greece), and Thermon at Aetolia, (Aetoloacarnania, western central Greece), have a north-south orientation of their main entrances. This is a rather rare alignment of temples in general and specifically of Apollo in classical Greece, where most of them have broadly an east-west orientation. Based on historical and mythological accounts, as well as astronomical orientation measurements, the northern direction orientation of these constructions may relate to the rare, albeit impressive, occurrence of aurorae borealis, the northern lights. These strong lights are attributed to god Apollo by the epithet ``hyperborean'', meaning to the northern lands. Attribution is supported by archaeomagnetic directional data accompanied by auroral occurrence during those times.

    It has been consistently demonstrated that initial exertion of self-control had negative influence on people's performance on subsequent self-control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state-oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self-control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Megalithic monuments have been intensively surveyed and studied from the archaeoastronomical point of view in the past decades. We have orientation measurements for over one thousand megalithic burial monuments in the Iberian Peninsula, from several different periods. These data, however, lack a sound understanding. A way to classify and start to understand such orientations is by means of statistical analysis of the data. A first attempt is done with simple statistical variables and a mere comparison between the different areas. In order to minimise the subjectivity in the process a further more complicated analysis is performed. Some interesting results linking the orientation and the geographical location will be presented. Finally I will present some models comparing the orientation of the megaliths in the Iberian Peninsula with the rising of the sun and the moon at several times of the year.

    Full Text Available In this article were presented the replication research of valuable orientations of modern young learners. In the experiment took part 200 pre-school children (100 boys and 100 girls, who are studying in the nurseries of Moscow and Moscow regions. To estimate the value orientations of modern young learners were used the diagnostic technique “Magic Flower”, developed by T.A. Repina. The results of the research were compared with the results obtained in the research of T.A. Repina. The results allow us to estimate value sphere of modern young learners and their peers of the 80s. There ambiguous influence on contemporary socio-cultural conditions of modern value orientations of children of preschool age. On the one hand, they do not lead to a distortion of the desire of children to communicate and interact, but on the other - to increase the orientation of children on their needs and requirements.

    The representation of orientation in primary visual cortex (V1) has been examined at a fine spatial scale corresponding to the columnar architecture. We present functional magnetic resonance imaging (fMRI) measurements providing evidence for a topographic map of orientation preference in human V1 at a much coarser scale, in register with the angular-position component of the retinotopic map of V1. This coarse-scale orientation map provides a parsimonious explanation for why multivariate pattern analysis methods succeed in decoding stimulus orientation from fMRI measurements, challenging the widely-held assumption that decoding results reflect sampling of spatial irregularities in the fine-scale columnar architecture. Decoding stimulus attributes and cognitive states from fMRI measurements has proven useful for a number of applications, but our results demonstrate that the interpretation cannot assume decoding reflects or exploits columnar organization.

    2013-01-01

    Typical spatial descriptions, such as "The car is in front of the house," describe the position of a located object (LO; e.g., the car) in space relative to a reference object (RO) whose location is known (e.g., the house). The orientation of the RO affects spatial language comprehension via the reference frame selection process. However, the effects of the LO's orientation on spatial language have not received great attention. This study explores whether the pure geometric information of the LO (e.g., its orientation) affects spatial language comprehension using placing and production tasks. Our results suggest that the orientation of the LO influences spatial language comprehension even in the absence of functional relationships. Copyright © 2013 Cognitive Science Society, Inc.

    Several retrospective and prospective studies have reported on the association between childhood gender variance and sexual orientation and gender discomfort in adulthood. In most of the retrospective studies, samples were drawn from the general population. The samples in the prospective studies consisted of clinically referred children. In understanding the extent to which the association applies for the general population, prospective studies using random samples are needed. This prospective study examined the association between childhood gender variance, and sexual orientation and gender discomfort in adulthood in the general population. In 1983, we measured childhood gender variance, in 406 boys and 473 girls. In 2007, sexual orientation and gender discomfort were assessed. Childhood gender variance was measured with two items from the Child Behavior Checklist/4-18. Sexual orientation was measured for four parameters of sexual orientation (attraction, fantasy, behavior, and identity). Gender discomfort was assessed by four questions (unhappiness and/or uncertainty about one's gender, wish or desire to be of the other gender, and consideration of living in the role of the other gender). For both men and women, the presence of childhood gender variance was associated with homosexuality for all four parameters of sexual orientation, but not with bisexuality. The report of adulthood homosexuality was 8 to 15 times higher for participants with a history of gender variance (10.2% to 12.2%), compared to participants without a history of gender variance (1.2% to 1.7%). The presence of childhood gender variance was not significantly associated with gender discomfort in adulthood. This study clearly showed a significant association between childhood gender variance and a homosexual sexual orientation in adulthood in the general population. In contrast to the findings in clinically referred gender-variant children, the presence of a homosexual sexual orientation in

  3. The effect of synaptic plasticity on orientation selectivity in a balanced model of primary visual cortex

    2015-01-01

    Orientation selectivity is ubiquitous in the primary visual cortex (V1) of mammals. In cats and monkeys, V1 displays spatially ordered maps of orientation preference. Instead, in mice, squirrels, and rats, orientation selective neurons in V1 are not spatially organized, giving rise to a seemingly random pattern usually referred to as a salt-and-pepper layout. The fact that such different organizations can sharpen orientation tuning leads to question the structural role of the intracortical connections; specifically the influence of plasticity and the generation of functional connectivity. In this work, we analyze the effect of plasticity processes on orientation selectivity for both scenarios. We study a computational model of layer 2/3 and a reduced one-dimensional model of orientation selective neurons, both in the balanced state. We analyze two plasticity mechanisms. The first one involves spike-timing dependent plasticity (STDP), while the second one considers the reconnection of the interactions according to the preferred orientations of the neurons. We find that under certain conditions STDP can indeed improve selectivity but it works in a somehow unexpected way, that is, effectively decreasing the modulated part of the intracortical connectivity as compared to the non-modulated part of it. For the reconnection mechanism we find that increasing functional connectivity leads, in fact, to a decrease in orientation selectivity if the network is in a stable balanced state. Both counterintuitive results are a consequence of the dynamics of the balanced state. We also find that selectivity can increase due to a reconnection process if the resulting connections give rise to an unstable balanced state. We compare these findings with recent experimental results. PMID:26347615

    In the heterozygote for the combination of an interchange (662W;3R/6R) and a Robertsonian split (3R) of rye, one type of adjacent orientation leads to trisomy in the progeny. Pollen mother cells with adjacent orientation of the translocation quinquivalent or with a trivalent and a bivalent were delayed in their development and appeared at prometaphase and metaphase later than cells with alternate quinquivalents. Delay in cell development is ascribed to unfavorable (early) prophase positioning of chromosomes.

    2013-01-01

    Faces and bodies share a great number of semantic attributes, such as gender, emotional expressiveness, and identity. Recent studies demonstrate that bodies can activate and modulate face perception. However, the nature of the face representation that is activated by bodies remains unknown. In particular, face and body representations have previously been shown to have a degree of orientation specificity. Here we use body-face adaptation aftereffects to test whether bodies activate face representations in an orientation-dependent manner. Specifically, we used a two-by-two design to examine the magnitude of the body-face aftereffect using upright and inverted body adaptors and upright and inverted face targets. All four conditions showed significant body-face adaptation. We found neither a main effect of body orientation nor an interaction between body and face orientation. There was a main effect of target face orientation, with inverted target faces showing larger aftereffects than upright target faces, consistent with traditional face-face adaptation. Taken together, these results suggest that bodies adapt and activate a relatively orientation-independent representation of faces.

    Background Approaches to measuring recovery orientation are needed, particularly for programs that may struggle with implementing recovery-oriented treatment. Objective A mixed methods comparative study was conducted to explore effective approaches to measuring recovery orientation of Assertive Community Treatment (ACT) teams. Design Two ACT teams exhibiting high and low recovery orientation were compared using surveys, treatment plan ratings, diaries of treatment visits, and team-leader-reported treatment control mechanisms. Results The recovery-oriented team differed on one survey measure (higher expectations for consumer recovery), treatment planning (greater consumer involvement and goal-directed content), and use of control mechanisms (less use of representative payee, agency-held lease, daily medication delivery, and family involvement). Staff and consumer diaries showed the most consistent differences (e.g., conveying hope and choice) and were the least susceptible to observer bias, but had the lowest response rates. Conclusions Several practices differentiate recovery orientation on ACT teams, and a mixed-methods assessment approach is feasible. PMID:23690285

    Full Text Available Previous research has demonstrated that consistency between people's behavior and their dispositions has predictive validity for judgments of regret. Research has also shown that differences in the personality variable of action orientation can influence ability to regulate negative affect. The present set of studies was designed to investigate how both consistency factors and action-state personality orientation influence judgments of regret. In Study 1, we used a recalled life event to provide a situation in which the person had experienced either an action or inaction. Individuals with an action orientation experienced more regret for situations involving inaction (staying home than situations involving action (going out. State-oriented individuals, however, maintained high levels of regret and did not differ in their regret ratings across either the action or inaction situations. In Study 2, participants made realistic choices involving either an action or inaction. Our findings revealed the same pattern of results: action-oriented individuals who chose an option that involved not acting (inaction had more regret that individuals who chose an option that involved acting (action. State-oriented individuals experienced high levels of regret regardless of whether they chose to act or not to act.

  14. Neurobiology of Gender Identity and Sexual Orientation.

    Roselli, Charles E

    2017-12-06

    Sexual identity and sexual orientation are independent components of a person's sexual identity. These dimensions are most often in harmony with each other and with an individual's genital sex, but not always. This review discusses the relationship of sexual identity and sexual orientation to prenatal factors that act to shape the development of the brain and the expression of sexual behaviors in animals and humans. One major influence discussed relates to organizational effects that the early hormone environment exerts on both gender identity and sexual orientation. Evidence that gender identity and sexual orientation are masculinized by prenatal exposure to testosterone and feminized in it absence is drawn from basic research in animals, correlations of biometric indices of androgen exposure and studies of clinical conditions associated with disorders in sexual development. There are, however, important exceptions to this theory that have yet to be resolved. Family and twin studies indicate that genes play a role, but no specific candidate genes have been identified. Evidence that relates to the number of older brothers implicates maternal immune responses as a contributing factor for male sexual orientation. It remains speculative how these influences might relate to each other and interact with postnatal socialization. Nonetheless, despite the many challenges to research in this area, existing empirical evidence makes it clear that there is a significant biological contribution to the development of an individual's sexual identity and sexual orientation.

    Dalia Baziukė

    2017-12-01

    Full Text Available Occurrence of the agent paradigm and its further applications have stimulated the emergence of new concepts and methodologies in computer science. Today terms like multi-agent system, agent-oriented methodology, and agent-oriented programming (AOP are widely used. The aim of this paper is to clarify the validity of usage of the terms AOP and AOP language. This is disclosed in two phases of an analysis process. Determining to which concepts, terms like agent, programming, object-oriented analysis and design, object-oriented programming, and agent-oriented analysis and design correspond is accomplished in the first phase. Analysis of several known agent system engineering methodologies in terms of key concepts used, final resulting artifacts, and their relationship with known programming paradigms and modern tools for agent system development is performed in the second phase. The research shows that in most cases in the final phase of agent system design and in the coding stage, the main artifact is an object, defined according to the rules of the object-oriented paradigm. Hence, we say that the computing society still does not have AOP owing to the lack of an AOP language. Thus, the term AOP is very often incorrectly assigned to agent system development frameworks that in most cases, transform agents into objects.DOI: 10.15181/csat.v5i1.1361

    Orientation selective neurons in the primary visual cortex typically respond to a range of orientations that covers 20 degrees or more, while in psychophysical experiments, orientation bandwidth is often clearly narrower. Here, we measure the orientation specificity of perceptual learning for vernier discriminations. More than 70 observers, in separate groups, practiced a vernier discrimination task with a constant stimulus orientation. After a 1h session of training, the vernier was rotated by 2 degrees, 4 degrees, 10 degrees, 20 degrees, 45 degrees or 90 degrees. Improvement through training in the first session transferred to the second session (tested on the next day) up to 10 degrees of stimulus rotation. We found no transfer for rotations of 20 degrees, 45 degrees and 90 degrees. Hence, the orientation half-bandwidth of perceptual learning is around 15 degrees, leading to a bandwidth of 30 degrees and corresponding to that of single neurons in early visual cortices, while being narrower than that in higher cortical areas.

    1981-01-01

    A Summary Time Oriented Medical Record System (STOR) has been designed as a potential replacement for the medical record for use in ambulatory care. As described at the Fourth Annual Symposium, this system has unique characteristics aimed specifically for management of patients with chronic diseases. It is hypothesized that this record design will improve information flow to practitioners at the time of decision-making in ambulatory care, while at the same time reducing manual recording requirements by the practitioner. This system has now been implemented in three specialty clinics at the University of California, San Francisco Medical Center. Rigorous evaluation techniques using prospective randomized control studies are being used in its evaluation. The clinical information includes patient problems, diagnoses, therapies, and ancillary test results. It is implemented on an IBM 4331 computer using the RAMIS data base management system.

  20. From Orientalism to neo-Orientalism: Early and contemporary constructions of Islam and the Muslim world

    Full Text Available The concept of Orientalism has been widely dealt with in the humanities and social sciences. It helps explain a peculiar construction of the Arab-Muslim world. Orientalism has operated in various historical paradigms but has always emphasised specific Western constructions of the Orient. Nowadays, the concept has metamorphosed to refer to new constructions of the Orient. New representations of Islam and the Muslim world are dominating the Western public space. The aim of this paper is twofold. It explores the historical development and paradigmatic shifts that have affected the concept of Orientalism. It then suggests that a neo-Orientalism has recently emerged, is less territorialised and operating within a new paradigm. It holds a new ideologically motivated agenda, constructs new objects, and feeds the social phenomenon called Islamophobia.

  1. Influence of the orientation of methylammonium lead iodide perovskite crystals on solar cell performance

    2014-08-01

    Full Text Available Perovskite solar cells are emerging as serious candidates for thin film photovoltaics with power conversion efficiencies already exceeding 16%. Devices based on a planar heterojunction architecture, where the MAPbI3 perovskite film is simply sandwiched between two charge selective extraction contacts, can be processed at low temperatures (<150 °C, making them particularly attractive for tandem and flexible applications. However, in this configuration, the perovskite crystals formed are more or less randomly oriented on the surface. Our results show that by increasing the conversion step temperature from room temperature to 60 °C, the perovskite crystal orientation on the substrate can be controlled. We find that films with a preferential orientation of the long axis of the tetragonal unit cell parallel to the substrate achieve the highest short circuit currents and correspondingly the highest photovoltaic performance.

    1989-06-01

    The purpose of this study was to describe home health agency preferences with respect to staff nurse qualifications, and practices in hiring and orienting new staff. An 85-item home health staff nurse selection and orientation questionnaire was used to collect data from a random sample of 287 midwestern home health agencies in 12 states. Qualifications rated most highly were medical-surgical experience, venipuncture skills, completion of a physical assessment course, intravenous therapy skills, and patient-teaching skills. With agency sponsorship (traditional, proprietary, and hospital-based) as the independent variable, the three types of agencies were significantly different on ratings of six qualifications and six orientation topics. None of the agencies rated a BSN degree as very important or required, and the same was true for completion of a student experience in community health nursing. Preference for qualifications in this study is consistent with increasing acuteness of patients' illness and technologic complexity of home care.

    Full Text Available Designing test cases and generating data are very important phases in software engineering these days. In order to generate test data, some generators such as random test data generators, data specification generators and path-oriented (Path-Wise test data generators are employed. One of the most important problems in the path-oriented test data generator is the lack of attention given to discovering faults by the test data. In this paper an approach is proposed to generate some test data automatically so that we can realize the goal of discovering more faults in less time. The number of faults near the boundaries of the input domain is more than the center, according to the Pareto 80–20 principle the test data of this approach will be generated at 20% of the allowable area boundary. To do this, we extracted the boundary hypercuboids and then the test data will be generated by exploiting these hypercuboids. The experimental results show that the fault detection probability and the fault detection speed are improved significantly, compared with the previous approaches. By generating data in this way, more faults are discovered in a short period of time which makes it more possible to deliver products on time.

  5. The diversity of quasars unified by accretion and orientation

    Quasars are rapidly accreting supermassive black holes at the centres of massive galaxies. They display a broad range of properties across all wavelengths, reflecting the diversity in the physical conditions of the regions close to the central engine. These properties, however, are not random, but form well-defined trends. The dominant trend is known as `Eigenvector 1', in which many properties correlate with the strength of optical iron and [O III] emission. The main physical driver of Eigenvector 1 has long been suspected to be the quasar luminosity normalized by the mass of the hole (the `Eddington ratio'), which is an important parameter of the black hole accretion process. But a definitive proof has been missing. Here we report an analysis of archival data that reveals that the Eddington ratio indeed drives Eigenvector 1. We also find that orientation plays a significant role in determining the observed kinematics of the gas in the broad-line region, implying a flattened, disk-like geometry for the fast-moving clouds close to the black hole. Our results show that most of the diversity of quasar phenomenology can be unified using two simple quantities: Eddington ratio and orientation.

    2005-06-01

    Full Text Available Aluminium-silicon alloys have been wide accepted in the automotive, electric and aerospace industries. Preferred orientation is a very common condition for metals and alloys. Particularly, aluminium induces texture during the forming process. The preparation of an aggregate with completely random crystal orientation is a difficult task. The present work was undertaken to analyse the texture by X-ray diffraction techniques, of three spray formed hypereutectic Al-Si alloys. Samples were taken from a billet of an experimental alloy (alloy 1 and were subsequently hot-rolled and cold-rolled (height reduction, 72% and 70%, respectively. The other used samples, alloys 2 and 3, were taken from cylinders liners. The results from the Laue camera showed texture just in the axial direction of alloy 3. The pole figures also indicated the presence of a typical low intensity deformation texture, especially for alloy 3. The spray formed microstructure, which is very fine, hinders the Al-Si texture formation during mechanical work.

    2016-01-01

    From the framework of Terror Management Theory, the objective of the present research is to analyze the effect of mortality salience (MS) on the minimization of Muslim terrorists’ secondary emotions (MSE, which can be understood as a particular kind of dehumanization), as a function of political orientation. An experimental design was used, in which the participants (university students, N= 293) were randomly assigned to a control or experimental group, their political orientation was taken note of, and they were asked to attribute emotions to Muslim terrorists. In accordance with the hypotheses, the results indicate that, among those supporting tenets of the political left, MS originates less minimization of secondary emotions of the terrorists (MSE). However, among people who stand on the right, MS inspires greater MSE (that is, a lower attribution of these emotions). These results support the thesis that the effects of MS are not to be found exclusively in conservative people, and that they do not necessarily imply a conservative shift, but constitute a polarization in previous ideological tendencies or cultural worldview.

  9. An event-based neurobiological recognition system with orientation detector for objects in multiple orientations

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available A new multiple orientation event-based neurobiological recognition system is proposed by integrating recognition and tracking function in this paper, which is used for asynchronous address-event representation (AER image sensors. The characteristic of this system has been enriched to recognize the objects in multiple orientations with only training samples moving in a single orientation. The system extracts multi-scale and multi-orientation line features inspired by models of the primate visual cortex. An orientation detector based on modified Gaussian blob tracking algorithm is introduced for object tracking and orientation detection. The orientation detector and feature extraction block work in simultaneous mode, without any increase in categorization time. An addresses lookup table (addresses LUT is also presented to adjust the feature maps by addresses mapping and reordering, and they are categorized in the trained spiking neural network. This recognition system is evaluated with the MNIST dataset which have played important roles in the development of computer vision, and the accuracy is increase owing to the use of both ON and OFF events. AER data acquired by a DVS are also tested on the system, such as moving digits, pokers, and vehicles. The experimental results show that the proposed system can realize event-based multi-orientation recognition.The work presented in this paper makes a number of contributions to the event-based vision processing system for multi-orientation object recognition. It develops a new tracking-recognition architecture to feedforward categorization system and an address reorder approach to classify multi-orientation objects using event-based data. It provides a new way to recognize multiple orientation objects with only samples in single orientation.

  14. Random matrices, random processes and integrable systems

    CERN Document Server

    2011-01-01

    This book explores the remarkable connections between two domains that, a priori, seem unrelated: Random matrices (together with associated random processes) and integrable systems. The relations between random matrix models and the theory of classical integrable systems have long been studied. These appear mainly in the deformation theory, when parameters characterizing the measures or the domain of localization of the eigenvalues are varied. The resulting differential equations determining the partition function and correlation functions are, remarkably, of the same type as certain equations appearing in the theory of integrable systems. They may be analyzed effectively through methods based upon the Riemann-Hilbert problem of analytic function theory and by related approaches to the study of nonlinear asymptotics in the large N limit. Associated with studies of matrix models are certain stochastic processes, the "Dyson processes", and their continuum diffusion limits, which govern the spectrum in random ma...

  15. Magnetic compass orientation in the European eel.

    Directory of Open Access Journals (Sweden)

    Caroline M F Durif

    Full Text Available European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km and orientation mechanisms are unknown. Several attempts have been made to prove the existence of magnetoreception in Anguilla sp., but none of these studies have demonstrated magnetic compass orientation in earth-strength magnetic field intensities. We tested eels in four altered magnetic field conditions where magnetic North was set at geographic North, South, East, or West. Eels oriented in a manner that was related to the tank in which they were housed before the test. At lower temperature (under 12°C, their orientation relative to magnetic North corresponded to the direction of their displacement from the holding tank. At higher temperatures (12-17°C, eels showed bimodal orientation along an axis perpendicular to the axis of their displacement. These temperature-related shifts in orientation may be linked to the changes in behavior that occur between the warm season (during which eels are foraging and the colder fall and winter (during which eels undertake their migrations. These observations support the conclusion that 1. eels have a magnetic compass, and 2. they use this sense to orient in a direction that they have registered moments before they are displaced. The adaptive advantage of having a magnetic compass and learning the direction in which they have been displaced becomes clear when set in the context of the eel's seaward migration. For example, if their migration is halted or blocked, as it is the case when environmental conditions become unfavorable or when they encounter a barrier, eels would be able to resume their movements along their old bearing when conditions become favorable again or when they pass by the barrier.

    2010-12-01

    Full Text Available Orientation: The main issue of this article concerns the construction and evaluation of an instrument measuring positive states and its relationship with entrepreneurship orientation.Research purpose: The principal objective of the study was the construction of a normative scale to measure the positive states associated with appreciative ability and to relate it to a scale of entrepreneurial orientation. A secondary objective was to determine whether there was a statistically significant relationship between the measures of the constructs and the biographical variables of gender and culture.Motivation: As appreciative ability is a relatively new construct and no instrument exists for measuring the positive states emanating from this construct, it was decided to develop such an instrument and to relate it to entrepreneurship orientation.Research design, approach and method: The primary data were obtained by means of the newly designed instrument, the Positive States Questionnaire and the Entrepreneurship Orientation Questionnaire. A convenience sample of 210 second year commerce students was drawn.Main findings: From a principal factor analysis applied to the two instruments, two factors each were obtained. A significantly high correlation was found, indicating a strong relationship between entrepreneurship orientation and the positive states. No significant differences were found between gender or population in the entrepreneurship orientation and positive states measures.Practical/managerial implications: The study produced an instrument with highly acceptable metrical properties which may be used in future studies and for entrepreneurship development.Contribution/value-add: The results of the study suggest that positive states are invaluable attributes for the entrepreneur and should be explored in the assessment and development of entrepreneurs.

  17. Hierarchical organisation in perception of orientation.

    1999-01-01

    According to Rock [1990, in The Legacy of Solomon Asch (Hillsdale, NJ: Lawrence Erlbaum Associates)], hierarchical organisation of perception describes cases in which the orientation of an object is affected by the immediately surrounding elements in the visual field. Various experiments were performed to study the hierarchical organisation of orientation perception. In most of them the rod-and-frame-illusion (RFI: change of the apparent vertical measured on a central rod surrounded by a tilted frame) was measured in the presence/absence of a second inner frame. The first three experiments showed that, when the inner frame is vertical, the direction and size of the illusion are consistent with expectancies based on the hierarchical organisation hypothesis. An analysis of published and unpublished data collected on a large number of subjects showed that orientational hierarchical effects are independent from the absolute size of the RFI. In experiments 4 to 7 we examined the perceptual conditions of the inner stimulus (enclosure, orientation, and presence of luminance borders) critical for obtaining a hierarchical organisation effect. Although an inner vertical square was effective in reducing the illusion (experiment 3), an inner circle enclosing the rod was ineffective (experiment 4). This indicates that definite orientation is necessary to modulate the illusion. However, orientational information provided by a vertical or horizontal rectangle presented near the rod, but not enclosing it, did not modulate the RFI (experiment 5). This suggests that the presence of a figure with oriented contours enclosing the rod is critical. In experiments 6 and 7 we studied whether the presence of luminance borders is important or whether the inner upright square might be effective also if made of subjective contours. When the subjective contour figure was salient and the observers perceived it clearly, its effectiveness in modulating the RFI was comparable to that observed with

    We study the relaxational critical dynamics of the three-dimensional random anisotropy magnets with the non-conserved n-component order parameter coupled to a conserved scalar density. In the random anisotropy magnets, the structural disorder is present in the form of local quenched anisotropy axes of random orientation. When the anisotropy axes are randomly distributed along the edges of the n-dimensional hypercube, asymptotical dynamical critical properties coincide with those of the random-site Ising model. However the structural disorder gives rise to considerable effects for non-asymptotic critical dynamics. We investigate this phenomenon by a field-theoretical renormalization group analysis in the two-loop order. We study critical slowing down and obtain quantitative estimates for the effective and asymptotic critical exponents of the order parameter and scalar density. The results predict complex scenarios for the effective critical exponent approaching the asymptotic regime.

  2. An Orientation Distribution Function for Trabecular Bone

    Energy Technology Data Exchange (ETDEWEB)

    Lawrence Livermore National Laboratory

    2004-10-08

    We describe a new method for quantifying the orientation of trabecular bone from three-dimensional images. Trabecular lattices from five human vertebrae were decomposed into individual trabecular elements, and the orientation, mass, and thickness of each element were recorded. Continuous functions that described the total mass (M({var_phi},{theta})) and mean thickness ({tau}({var_phi},{theta})) of all trabeculae as a function of orientation were derived. The results were compared with experimental measurements of the elastic modulus in the three principal anatomic directions. A power law scaling relationship between the anisotropies in mass and elastic modulus was observed; the scaling exponent was 1.41 (R{sup 2} = 0.88). As expected, the preponderance of trabecular mass was oriented along the cranial-caudal direction; on average, there was 3.4 times more mass oriented vertically than horizontally. Moreover, the vertical trabeculae were 30% thicker, on average, than the horizontal trabeculae. The vertical trabecular thickness was inversely related to the connectivity (R{sup 2} = 0.70; p = 0.07), suggesting a possible organization into either few, thick trabeculae or many thin trabeculae. The method, which accounts for the mechanical connectedness of the lattice, provides a rapid way to both visualize and quantify the three-dimensional organization of trabecular bone.

  3. Spatial orientation shrinks and expands psychological distance.

    2014-07-01

    Being objectively close to or far from a place changes how people perceive the location of that place in a subjective, psychological sense. In the six studies reported here, we investigated whether people's spatial orientation (defined as moving toward or away from a place) will produce similar effects-by specifically influencing psychological closeness in each of its forms (i.e., spatial, temporal, probabilistic, and social distance). Orientation influenced subjective spatial distance at various levels of objective distance (Study 1), regardless of the direction people were facing (Study 2). In addition, when spatially oriented toward, rather than away from, a particular place, participants felt that events there had occurred more recently (Studies 3a and 3b) and that events there would be more likely to occur (Study 4). Finally, participants felt more similarity to people who were spatially oriented toward them than to people who were spatially oriented away from them (Study 5). Our investigation broadens the study of psychological distance from static spatial locations to dynamically moving points in space. © The Author(s) 2014.

  4. Optimising Mobile Mapping System Laser Scanner Orientation

    Directory of Open Access Journals (Sweden)

    Conor Cahalane

    2015-02-01

    Full Text Available Multiple laser scanner hardware configurations can be applied to Mobile Mapping Systems. As best practice, laser scanners are rotated horizontally or inclined vertically to increase the probability of contact between the laser scan plane and any surfaces that are perpendicular to the direction of travel. Vertical inclinations also maximise the number of scan profiles striking narrow vertical features, something that can be of use when trying to recognise features. Adding a second scanner allows an MMS to capture more data and improve laser coverage of an area by filling in laser shadows. However, in any MMS the orientation of each scanner on the platform must be decided upon. Changes in the horizontal or vertical orientations of the scanner can increase the range to vertical targets and the road surface, with excessive scanner angles lowering point density significantly. Limited information is available to assist the manufacturers or operators in identifying the optimal scanner orientation for roadside surveys. The method proposed in this paper applies 3D surface normals and geometric formulae to assess the influence of scanner orientation on point distribution. It was demonstrated that by changing the orientation of the scanner the number of pulses striking a target could be greatly increased, and the number of profiles intersecting with the target could also be increased—something that is particularly important for narrow vertical features. The importance of identifying the correct trade-off between the number of profiles intersecting with the target and the point spacing was also raised.

  5. A novel orientation code for face recognition

    Zheng, Yufeng

    2011-06-01

    A novel orientation code is proposed for face recognition applications in this paper. Gabor wavelet transform is a common tool for orientation analysis in a 2D image; whereas Hamming distance is an efficient distance measurement for multiple classifications such as face identification. Specifically, at each frequency band, an index number representing the strongest orientational response is selected, and then encoded in binary format to favor the Hamming distance calculation. Multiple-band orientation codes are then organized into a face pattern byte (FPB) by using order statistics. With the FPB, Hamming distances are calculated and compared to achieve face identification. The FPB has the dimensionality of 8 bits per pixel and its performance will be compared to that of FPW (face pattern word, 32 bits per pixel). The dimensionality of FPB can be further reduced down to 4 bits per pixel, called face pattern nibble (FPN). Experimental results with visible and thermal face databases show that the proposed orientation code for face recognition is very promising in contrast with classical methods such as PCA.

    Objectives The construction industry accounted for >20% of all fatal occupational accidents in Europe in 2014. Leadership is an essential antecedent to occupational safety. The aim of the present study was to assess the influence of transformational, active transactional, rule-oriented, participative, and laissez-faire leadership on safety climate, safety behavior, and accidents in the Swedish and Danish construction industry. Sweden and Denmark are similar countries but have a large difference in occupational accidents rates. Methods A questionnaire study was conducted among a random sample of construction workers in both countries: 811 construction workers from 85 sites responded, resulting in site and individual response rates of 73% and 64%, respectively. Results The results indicated that transformational, active transactional, rule-oriented and participative leadership predict positive safety outcomes, and laissez-faire leadership predict negative safety outcomes. For example, rule-oriented leadership predicts a superior safety climate (β=0.40, Pleadership on workers' safety behavior was moderated by the level of participative leadership (β=0.10, Pleadership behaviors on safety outcomes were largely similar in Sweden and Denmark. Rule-oriented and participative leadership were more common in the Swedish than Danish construction industry, which may partly explain the difference in occupational accident rates. Conclusions Applying less laissez-faire leadership and more transformational, active transactional, participative and rule-oriented leadership appears to be an effective way for construction site managers to improve occupational safety in the industry.

  10. Multiscale Shannon's Entropy Modeling of Orientation and Distance in Steel Fiber Micro-Tomography Data.

    Chiverton, John P; Ige, Olubisi; Barnett, Stephanie J; Parry, Tony

    2017-11-01

    This paper is concerned with the modeling and analysis of the orientation and distance between steel fibers in X-ray micro-tomography data. The advantage of combining both orientation and separation in a model is that it helps provide a detailed understanding of how the steel fibers are arranged, which is easy to compare. The developed models are designed to summarize the randomness of the orientation distribution of the steel fibers both locally and across an entire volume based on multiscale entropy. Theoretical modeling, simulation, and application to real imaging data are shown here. The theoretical modeling of multiscale entropy for orientation includes a proof showing the final form of the multiscale taken over a linear range of scales. A series of image processing operations are also included to overcome interslice connectivity issues to help derive the statistical descriptions of the orientation distributions of the steel fibers. The results demonstrate that multiscale entropy provides unique insights into both simulated and real imaging data of steel fiber reinforced concrete.

    Full Text Available Teacher orientation to the inculcation of values across school curriculum-a function of the teacher knowledge and attitudes-has been conceptualised as his or her (1 identification with the goals of the curriculum, and (2 conformity with the predetermined instructional behaviours. Based on this framework, the study explored the construct of teacher orientation to the inculcation of values across school subjects. More specifically, the study examined the likelihood of two underlying dimensions explaining the presence of variability in teacher orientation and the reliability of the dimensions. Using a 15-item instrument developed earlier for a descriptive inquiry, the present study measured and analysed responses from 103 secondary school teachers from two randomly selected schools. To arrive at the conclusions, the study applied principal component analysis and Cronbach's alpha procedures. The results suggested that teacher orientation to value inculcation is a multidimensional construct. The more reliable dimensions of Teacher Orientation were found to be goal identification, conformity to planning tasks, and conformity to delivery tasks. The results add new information to, and may serve as a guide for future research.

    Full Text Available Narrative historians have long exhibited greater or lesser awareness of their own agency as authors, where absolute objectivity is precluded. Indeed, historians' reports of the past include their own orientations or attitudes, which can also be examined in historians' autobiographies. In this article we present a study in which a questionnaire was used to ask historians about their orientations toward their subject matter. How do historians approach their work as agents and what might this reveal about the nature of historical production? In our model, we have distinguished four criteria, sorted the answers using statistical analysis and weighed the results in the light of our expectations. Indeed, by exploring historians' presuppositions (exemplified in examining historians' autobiographies, historical production can be seen as an institutional process also steered by historians' orientations and agency with important philosophical implications for the integral relationship between historians' public and private roles.

    2017-07-01

    Graphene, a two-dimensional (2D) material, is an important constituent part for the development of mechanic, electronic and photonic systems due to its remarkable properties, however, wrinkling is a ubiquitous phenomenon in 2D membranes. As a 2D material with atomic thickness, graphene is found to be wrinkled easily because of its relatively low bending rigidity, and besides, wrinkle affects graphene’s remarkable physical property severely. Despite their prevalence and potential impact on large-scale graphene properties, only a several approaches have been dedicated to control their structural morphology and orientation by transferring graphene onto polymer substrates. Here we report a new route to control the orientation of wrinkles by directly applying external mechanical strains to metal substrates until plastic deformation happens. By changing direction and magnitude of tension strain, wrinkles with different spacing but all with orientations perpendicular to the tensile direction can be obtained.

    2017-11-01

    Full Text Available We review the results of a wide range of nuclear magnetic resonance (NMRmeasurements of the local order parameters and the molecular dynamics of solid ortho-para hydrogen mixtures and solid nitrogen-argon mixtures that form novel molecular orientational glass states at low temperatures. From the NMR measurements, the distribution of the order parameters can be deduced and, in terms of simple models, used to analyze the thermodynamic measurements of the heat capacities of these systems. In addition, studies of the dielectric susceptibilities of the nitrogen-argon mixtures are reviewed in terms of replica symmetry breaking analogous to that observed for spin glass states. It is shown that this wide set of experimental results is consistent with orientation or quadrupolar glass ordering of the orientational degrees of freedom.

    1993-03-01

    Homosexual female probands with monozygotic cotwins, dizygotic cotwins, or adoptive sisters were recruited using homophile publications. Sexual orientation of relatives was assessed either by asking relatives directly, or, when this was impossible, by asking the probands. Of the relatives whose sexual orientation could be confidently rated, 34 (48%) of 71 monozygotic cotwins, six (16%) of 37 dizygotic cotwins, and two (6%) of 35 adoptive sisters were homosexual. Probands also reported 10 (14%) nontwin biologic sisters to be homosexual, although those sisters were not contacted to confirm their orientations. Heritabilities were significant using a wide range of assumptions about both the base rate of homosexuality in the population and ascertainment bias. The likelihood that a monozygotic cotwin would also be homosexual was unrelated to measured characteristics of the proband such as self-reported history of childhood gender nonconformity. Concordant monozygotic twins reported similar levels of childhood gender nonconformity.

    Full Text Available The study is aimed at investigating the dynamics of students’ value orientation at the pedagogic higher school. The subject of the research incorporates the value-motivation sphere as being the component of students’ cognitive interest. The research methodology is based on the system determinism principle and combines the theoretical and practical substantiation of the value orientation problem as the main component of students’ cognitive interest. The research results referred to the professional activity values, growing year after year during the undergraduate course, can be taken into account in developing the value–motivation sphere of the studentship. The research shows that the proper psychological conditions created in the educational environment make the develop- ment of the value orientation system more successful.

    Sulfate attack and the accompanying crystallization of fibrous ettringite [Ca{sub 6}Al{sub 2}(OH){sub 12}(SO{sub 4}){sub 3} {center_dot} 26H{sub 2}O] cause cracking and loss of strength in concrete structures. Hard synchrotron X-ray microdiffraction is used to quantify the orientation distribution of ettringite crystals. Diffraction images are analyzed using the Rietveld method to obtain information on textures. The analysis reveals that the c axes of the trigonal crystallites are preferentially oriented perpendicular to the fracture surfaces. By averaging single-crystal elastic properties over the orientation distribution, it is possible to estimate the elastic anisotropy of ettringite aggregates.

    The development of software systems for the biosciences is always closely connected to experimental practice. Programs must be able to handle the inherent complexity and heterogeneous structure of biological systems in combination with the measuring equipment. Moreover, a high degree of flexibility is required to treat rapidly changing experimental conditions. Object-oriented methodology seems to be well suited for this purpose. It enables an evolutionary approach to software development that still maintains a high degree of modularity. This paper presents experience with object-oriented technology gathered during several years of programming in the fields of bioprocess development and metabolic engineering. It concentrates on the aspects of experimental support, data analysis, interaction and visualization. Several examples are presented and discussed in the general context of the experimental cycle of knowledge acquisition, thus pointing out the benefits and problems of object-oriented technology in the specific application field of the biosciences. Finally, some strategies for future development are described.

    Full Text Available Cerium oxide films of preferred orientation are electrodeposited under anodic conditions. A complexing ligand, acetate, was used to stabilize the cerium (III ion in solution for deposition of the thin films. Fourier transform infrared spectroscopy showed that the ligand and metal tended to bind as a weakly bidentate complex. The crystallite size of the films was in the nanometer range as shown by Raman spectroscopy and was calculated from X-ray diffraction data. Crystallite sizes from 6 to 20 nm were obtained under the anodic deposition conditions. Sintering of the (111 oriented films showed an increase in the (111 orientation with temperatures up to 900°C. Also, the crystallite size increased from 20 nm to 120 nm under sintering conditions. Addition of the deposited films to the substrate improved corrosion resistance for the substrate.

    We will present x-ray and mechanical studies of oriented phases of cocoa butter. The structural elements of foods play an important role in determining such things as quality and shelf stability. The specific structure and properties of cocoa butter, however, are complicated due to the ability of the cocoa butter to form crystals in six polymorphic forms. Recent work has shown that the application of shear not only accelerates the transitions to more stable polymorphs, but also causes orientation of the crystallites[1]. The implications of orientation on the structures formed under conditions of shear and cooling will be described using x-ray diffraction and mechanical measurements. 1 G. Mazzanti, S. E. Guthrie, E.

    2013-02-06

    We demonstrate that the thermoelectric properties of highly oriented Al-doped zinc oxide (AZO) thin films can be improved by controlling their crystal orientation. The crystal orientation of the AZO films was changed by changing the temperature of the laser deposition process on LaAlO3 (100) substrates. The change in surface termination of the LaAlO3 substrate with temperature induces a change in AZO film orientation. The anisotropic nature of electrical conductivity and Seebeck coefficient of the AZO films showed a favored thermoelectric performance in c-axis oriented films. These films gave the highest power factor of 0.26 W m−1 K−1 at 740 K.

    Mesoporous semiconductor films are of considerable interest for applications in photoelectrochemical devices, however, despite intensive research till now, their charge transport properties remain significantly lower than their single-crystal counterparts. Herein, we report a novel low-temperature template-free technique for growing high surface area mesoporous anatase TiO2 films with a preferred [001] crystalline-orientation on FTO-coated glass substrate. Compared to mesoporous films that comprised of randomly oriented crystallites, the uniaxial orientation enables a 100-fold increase in the rate of electron transport. The uniaxially oriented mesoporous anatase TiO2 films exhibit should greatly facilitate the development and application of photoelectrochemical and electrochemical devices.

    Hao Chang

    Full Text Available Planar cell polarity (PCP signaling controls the global orientation of surface structures, such as hairs and bristles, in both vertebrates and invertebrates. In Frizzled6(-/- (Fz6(-/- mice, hair follicle orientations on the head and back are nearly random at birth, but reorient during early postnatal development to eventually generate a nearly parallel anterior-to-posterior array. We report the identification of a naturally occurring exon 5 deletion in Astrotactin2 (Astn2 that acts as a recessive genetic modifier of the Fz6(-/- hair patterning phenotype. A genetically engineered Astn2 exon 5 deletion recapitulates the modifier phenotype. In Fz6(-/-;Astn2(ex5del/del mice, hair orientation on the back is subtly biased from posterior-to-anterior, leading to a 180-degree orientation reversal in mature mice. These experiments suggest that Astn2, an endosomal membrane protein, modulates PCP signaling.

    Full Text Available When planning a randomized clinical trial, careful consideration must be given to how participants are selected for various arms of a study. Selection and accidental bias may occur when participants are not assigned to study groups with equal probability. A simple random allocation scheme is a process by which each participant has equal likelihood of being assigned to treatment versus referent groups. However, by chance an unequal number of individuals may be assigned to each arm of the study and thus decrease the power to detect statistically significant differences between groups. Block randomization is a commonly used technique in clinical trial design to reduce bias and achieve balance in the allocation of participants to treatment arms, especially when the sample size is small. This method increases the probability that each arm will contain an equal number of individuals by sequencing participant assignments by block. Yet still, the allocation process may be predictable, for example, when the investigator is not blind and the block size is fixed. This paper provides an overview of blocked randomization and illustrates how to avoid selection bias by using random block sizes.

    Full Text Available The article solves two relevant problems related to the implementation of the institutional assessment of environmentally oriented subsoil use: 1 the definition of the ‘environmental security’ and 2 the determination of the development level of institutional bases of environmentally oriented subsoil use including the institutional capacity of subsoil use and institutional capacity of environmental security. The article shows an analysis of the existing definitions of “environmental security” and offers the own one. Despite the significant national and foreign experience in the institutional capacity assessment of various processes, there are still some difficulties in defining and measuring the institutional capacity. We eliminate these difficulties by employing 1 original factors, previously identified, and the content of the “institutional capacity” term; 2 quality characteristics for the institutional capacity assessment of the process regulated at the macroeconomic level, and 3 a consistent methodological tool for the institutional assessment of environmentally oriented subsoil use. The study is based on the hypothesis of the necessity of legal and discreet state intervention in the process of subsoil use. Therefore, we identify the evaluation indicator of state regulation in the environmentally oriented subsoil use as the institutional capacity level calculated by using the fuzzy-set theory. As a result, the institutional capacity levels of the environmentally oriented subsoil use have been defined for both the transport corridor «Arctic-Central Asia» and for the countries composing it. The obtained values of the assessment of institutional capacity levels of the environmentally oriented subsoil use can serve as a basis for identifying the vector of its increase

A drop of an aqueous dispersion of particles is placed on the surface and water vaporizes under controlled relative humidity. Three requirements are essential for uniform coverage: particle dispersion should not contain aggregates, a weak attraction between particles and surface is needed, and evaporation rate should be low. Aggregates are removed by stirring/sonication. Weak attraction is realized by introducing cationic groups to the surface. Insight into the mechanisms of the so-called coffee stain effect is also provided.

    Recovery-oriented mental health services promote the principles of recovery, such as hope and optimism, and are characterized by a personalized approach to developing consumer self-determination. Nurse leaders are increasingly developing such services as social enterprises, but there is limited research on the leadership of these programs. Leading a recovery-oriented mental health nurse social enterprise requires visionary leadership, collaboration with consumers and local health providers, financial viability, and commitment to recovery-focused practice. This article describes the framework of an Australian mental health nursing social enterprise, including the service attributes and leadership lessons that have been learned from developing program sustainability.

    The aim of this paper is to review available knowledge on sexual orientation and mental health, especially for women. Papers published in English or French, between 1997 and 2007, were selected in PubMed using the following keywords "homosexuality/sexual orientation and mental health/depression/suicide". To be retained, papers had to contain findings from quantitative surveys comparing homosexual and heterosexual adults. In all, this review analyses 22 papers including two that are based on the same survey. This review found a general pattern of poorer mental health for homosexuals and even more so for bisexuals compared to heterosexuals. Results are especially consistent regarding elevated risk of suicide attempts.

The homosexual index men report a significant excess of homosexual brothers and more distant male relatives but not of homosexual sisters or female relatives. Moreover, the percentage of homosexual brothers increases with the Kinsey rating of the index subjects. Overall, about 25% of brothers of homosexual men are reported also to be homosexual.

    Full Text Available Multilateral well drilling and completion technology reduces well development cost and increases effectively the benefit and productivity of oil & gas well, which is widely used and expanded in recent years at home and abroad. Whipstock packer oriented perforating technology, a critical step in multilateral well drilling and completion, is for perforating whipstock packer and communicating lower branch wellbore. This technology meets the higher requirement of orientation and accuracy of penetration, perforator being able to perforate whipstock packer but not perforate outer casing of whipstock, and also meets complicated operation process.

    Bertelsen, Kresten

    This thesis is concerned with driving forward oriented solid-state NMR spectroscopy as a viable technique for studying peptides in membrane bilayers. I will show that structural heterogeneity is an intrinsic part of the peptide/lipid system and that NMR can be used to characterize static...... and dynamic structural features of the peptides and its local surroundings. In fact one need to take into account the dynamical features of the system in order to correctly predict the structure from oriented solid-state NMR spectra.      ...

  6. Random walks, random fields, and disordered systems

    Černý, Jiří; Kotecký, Roman

    2015-01-01

    Focusing on the mathematics that lies at the intersection of probability theory, statistical physics, combinatorics and computer science, this volume collects together lecture notes on recent developments in the area. The common ground of these subjects is perhaps best described by the three terms in the title: Random Walks, Random Fields and Disordered Systems. The specific topics covered include a study of Branching Brownian Motion from the perspective of disordered (spin-glass) systems, a detailed analysis of weakly self-avoiding random walks in four spatial dimensions via methods of field theory and the renormalization group, a study of phase transitions in disordered discrete structures using a rigorous version of the cavity method, a survey of recent work on interacting polymers in the ballisticity regime and, finally, a treatise on two-dimensional loop-soup models and their connection to conformally invariant systems and the Gaussian Free Field. The notes are aimed at early graduate students with a mod...

  7. History-Dependent Patterns in Randomly Perturbed Nematic Liquid Crystals

    2013-01-01

    Full Text Available We study the characteristics of nematic structures in a randomly perturbed nematic liquid crystal (LC phase. We focus on the impact of the samples history on the universal behavior. The obtained results are of interest for every randomly perturbed system exhibiting a continuous symmetry-breaking phase transition. A semimicroscopic lattice simulation is used where the LC molecules are treated as cylindrically symmetric, rod-like objects interacting via a Lebwohl-Lasher (LL interaction. Pure LC systems exhibit a first order phase transition into the orientationally ordered nematic phase at T=Tc on lowering the temperature T. The orientational ordering of LC molecules is perturbed by the quenched, randomly distributed rod-like impurities of concentration p. Their orientation is randomly distributed, and they are coupled with the LC molecules via an LL-type interaction. Only concentrations below the percolation threshold are considered. The key macroscopic characteristics of perturbed LC structures in the symmetry-broken nematic phase are analyzed for two qualitatively different histories at T≪Tc. We demonstrate that, for a weak enough interaction among the LC molecules and impurities, qualitatively different history-dependent states could be obtained. These states could exhibit either short-range, quasi-long-range, or even long-range order.

    Random numbers are a fundamental resource in science and engineering with important applications in simulation and cryptography. The inherent randomness at the core of quantum mechanics makes quantum systems a perfect source of entropy. Quantum random number generation is one of the most mature quantum technologies with many alternative generation methods. This review discusses the different technologies in quantum random number generation from the early devices based on radioactive decay to the multiple ways to use the quantum states of light to gather entropy from a quantum origin. Randomness extraction and amplification and the notable possibility of generating trusted random numbers even with untrusted hardware using device-independent generation protocols are also discussed.

    We propose a relaxed privacy definition called {\\em random differential privacy} (RDP). Differential privacy requires that adding any new observation to a database will have small effect on the output of the data-release procedure. Random differential privacy requires that adding a {\\em randomly drawn new observation} to a database will have small effect on the output. We show an analog of the composition property of differentially private procedures which applies to our new definition. We sh...
