Full Text Available The spike trains of retinal ganglion cells (RGCs are the only source of visual information to the brain. Here, we genetically identify an RGC type in mice that functions as a pixel encoder and increases firing to light increments (PixON-RGC. PixON-RGCs have medium-sized dendritic arbors and non-canonical center-surround receptive fields. From their receptive field center, PixON-RGCs receive only excitatory input, which encodes contrast and spatial information linearly. From their receptive field surround, PixON-RGCs receive only inhibitory input, which is temporally matched to the excitatory center input. As a result, the firing rate of PixON-RGCs linearly encodes local image contrast. Spatially offset (i.e., truly lateral inhibition of PixON-RGCs arises from spiking GABAergic amacrine cells. The receptive field organization of PixON-RGCs is independent of stimulus wavelength (i.e., achromatic. PixON-RGCs project predominantly to the dorsal lateral geniculate nucleus (dLGN of the thalamus and likely contribute to visual perception.

In a previous work, we introduced a computational model of area 3b which is built upon the neural field theory and receives input from a simplified model of the index distal finger pad populated by a random set of touch receptors (Merkell cells). This model has been shown to be able to self-organize following the random stimulation of the finger pad model and to cope, to some extent, with cortical or skin lesions. The main hypothesis of the model is that learning of skin representations occurs at the thalamo-cortical level while cortico-cortical connections serve a stereotyped competition mechanism that shapes the receptive fields. To further assess this hypothesis and the validity of the model, we reproduced in this article the exact experimental protocol of DiCarlo et al. that has been used to examine the structure of receptive fields in area 3b of the primary somatosensory cortex. Using the same analysis toolset, the model yields consistent results, having most of the receptive fields to contain a single region of excitation and one to several regions of inhibition. We further proceeded our study using a dynamic competition that deeply influences the formation of the receptive fields. We hypothesized this dynamic competition to correspond to some form of somatosensory attention that may help to precisely shape the receptive fields. To test this hypothesis, we designed a protocol where an arbitrary region of interest is delineated on the index distal finger pad and we either (1) instructed explicitly the model to attend to this region (simulating an attentional signal) (2) preferentially trained the model on this region or (3) combined the two aforementioned protocols simultaneously. Results tend to confirm that dynamic competition leads to shrunken receptive fields and its joint interaction with intensive training promotes a massive receptive fields migration and shrinkage.

Expectations, especially those formed on the basis of extensive training, can substantially enhance visual performance. However, it is not clear that the physiological mechanisms underlying this enhancement are identical to those examined by experiments in which attention is directed by explicit instructions rather than strong expectations. To study the changes in visual representations associated with strong expectations, we trained animals to detect a brief motion pulse that was embedded in noise. Because the nature of the pulse and the statistics of its appearance were well known to the animals, they formed strong expectations which determined their behavioral performance. We used white-noise methods to infer the receptive field structure of single neurons in area MT while they were performing this task. Incorporating non-linearities, we compared receptive fields during periods of time when the animals were expecting the motion pulse with periods of time when they were not. We found receptive field changes consistent with an increased reliability in signaling pulse occurrence. Moreover, these changes were not consistent with a simple gain modulation. The results suggest that strong expectations can create very specific changes in the visual representations at a cellular level to enhance performance. Copyright 2009 Elsevier Ltd.

Two-dimensional receptive-field organization in striate cortical neurons of the cat.

Sun, M; Bonds, A B

1994-01-01

The two-dimensional organization of receptive fields (RFs) of 44 cells in the cat visual cortex and four cells from the cat LGN was measured by stimulation with either dots or bars of light. The light bars were presented in different positions and orientations centered on the RFs. The RFs found were arbitrarily divided into four general types: Punctate, resembling DOG filters (11%); those resembling Gabor filters (9%); elongate (36%); and multipeaked-type (44%). Elongate RFs, usually found in simple cells, could show more than one excitatory band or bifurcation of excitatory regions. Although regions inhibitory to a given stimulus transition (e.g. ON) often coincided with regions excitatory to the opposite transition (e.g. OFF), this was by no means the rule. Measurements were highly repeatable and stable over periods of at least 1 h. A comparison between measurements made with dots and with bars showed reasonable matches in about 40% of the cases. In general, bar-based measurements revealed larger RFs with more structure, especially with respect to inhibitory regions. Inactivation of lower cortical layers (V-VI) by local GABA injection was found to reduce sharpness of detail and to increase both receptive-field size and noise in upper layer cells, suggesting vertically organized RF mechanisms. Across the population, some cells bore close resemblance to theoretically proposed filters, while others had a complexity that was clearly not generalizable, to the extent that they seemed more suited to detection of specific structures. We would speculate that the broadly varying forms of cat cortical receptive fields result from developmental processes akin to those that form ocular-dominance columns, but on a smaller scale.

Extracranial robotic radiotherapy employs external markers and a correlation model to trace the tumor motion caused by the respiration. The real-time tracking of tumor motion however requires a prediction model to compensate the latencies induced by the software (image data acquisition and processing) and hardware (mechanical and kinematic) limitations of the treatment system. A new prediction algorithm based on local receptive fields extreme learning machines (pLRF-ELM) is proposed for respiratory motion prediction. All the existing respiratory motion prediction methods model the non-stationary respiratory motion traces directly to predict the future values. Unlike these existing methods, the pLRF-ELM performs prediction by modeling the higher-level features obtained by mapping the raw respiratory motion into the random feature space of ELM instead of directly modeling the raw respiratory motion. The developed method is evaluated using the dataset acquired from 31 patients for two horizons in-line with the latencies of treatment systems like CyberKnife. Results showed that pLRF-ELM is superior to that of existing prediction methods. Results further highlight that the abstracted higher-level features are suitable to approximate the nonlinear and non-stationary characteristics of respiratory motion for accurate prediction.

Population receptive field (pRF) measurements of chromatic responses in human visual cortex using fMRI.

Welbourne, Lauren E; Morland, Antony B; Wade, Alex R

2018-02-15

The spatial sensitivity of the human visual system depends on stimulus color: achromatic gratings can be resolved at relatively high spatial frequencies while sensitivity to isoluminant color contrast tends to be more low-pass. Models of early spatial vision often assume that the receptive field size of pattern-sensitive neurons is correlated with their spatial frequency sensitivity - larger receptive fields are typically associated with lower optimal spatial frequency. A strong prediction of this model is that neurons coding isoluminant chromatic patterns should have, on average, a larger receptive field size than neurons sensitive to achromatic patterns. Here, we test this assumption using functional magnetic resonance imaging (fMRI). We show that while spatial frequency sensitivity depends on chromaticity in the manner predicted by behavioral measurements, population receptive field (pRF) size measurements show no such dependency. At any given eccentricity, the mean pRF size for neuronal populations driven by luminance, opponent red/green and S-cone isolating contrast, are identical. Changes in pRF size (for example, an increase with eccentricity and visual area hierarchy) are also identical across the three chromatic conditions. These results suggest that fMRI measurements of receptive field size and spatial resolution can be decoupled under some circumstances - potentially reflecting a fundamental dissociation between these parameters at the level of neuronal populations.

Fast and robust estimation of spectro-temporal receptive fields using stochastic approximations.

The receptive field (RF) represents the signal preferences of sensory neurons and is the primary analysis method for understanding sensory coding. While it is essential to estimate a neuron's RF, finding numerical solutions to increasingly complex RF models can become computationally intensive, in particular for high-dimensional stimuli or when many neurons are involved. Here we propose an optimization scheme based on stochastic approximations that facilitate this task. The basic idea is to derive solutions on a random subset rather than computing the full solution on the available data set. To test this, we applied different optimization schemes based on stochastic gradient descent (SGD) to both the generalized linear model (GLM) and a recently developed classification-based RF estimation approach. Using simulated and recorded responses, we demonstrate that RF parameter optimization based on state-of-the-art SGD algorithms produces robust estimates of the spectro-temporal receptive field (STRF). Results on recordings from the auditory midbrain demonstrate that stochastic approximations preserve both predictive power and tuning properties of STRFs. A correlation of 0.93 with the STRF derived from the full solution may be obtained in less than 10% of the full solution's estimation time. We also present an on-line algorithm that allows simultaneous monitoring of STRF properties of more than 30 neurons on a single computer. The proposed approach may not only prove helpful for large-scale recordings but also provides a more comprehensive characterization of neural tuning in experiments than standard tuning curves.

The pulvinar is the largest extrageniculate thalamic visual nucleus in mammals. It establishes reciprocal connections with virtually all visual cortexes and likely plays a role in transthalamic cortico-cortical communication. In cats, the lateral posterior nucleus (LP) of the LP-pulvinar complex can be subdivided in two subregions, the lateral (LPl) and medial (LPm) parts, which receive a predominant input from the striate cortex and the superior colliculus, respectively. Here, we revisit the receptive field structure of LPl and LPm cells in anesthetized cats by determining their first-order spatiotemporal profiles through reverse correlation analysis following sparse noise stimulation. Our data reveal the existence of previously unidentified receptive field profiles in the LP nucleus both in space and time domains. While some cells responded to only one stimulus polarity, the majority of neurons had receptive fields comprised of bright and dark responsive subfields. For these neurons, dark subfields' size was larger than that of bright subfields. A variety of receptive field spatial organization types were identified, ranging from totally overlapped to segregated bright and dark subfields. In the time domain, a large spectrum of activity overlap was found, from cells with temporally coinciding subfield activity to neurons with distinct, time-dissociated subfield peak activity windows. We also found LP neurons with space-time inseparable receptive fields and neurons with multiple activity periods. Finally, a substantial degree of homology was found between LPl and LPm first-order receptive field spatiotemporal profiles, suggesting a high integration of cortical and subcortical inputs within the LP-pulvinar complex.

Comparing different stimulus configurations for population receptive field mapping in human fMRI

2015-02-01

Full Text Available Population receptive field (pRF mapping is a widely used approach to measuring aggregate human visual receptive field properties by recording non-invasive signals using functional MRI. Despite growing interest, no study to date has systematically investigated the effects of different stimulus configurations on pRF estimates from human visual cortex. Here we compared the effects of three different stimulus configurations on a model-based approach to pRF estimation: size-invariant bars and eccentricity-scaled bars defined in Cartesian coordinates and traveling along the cardinal axes, and a novel simultaneous ‘wedge and ring’ stimulus defined in polar coordinates, systematically covering polar and eccentricity axes. We found that the presence or absence of eccentricity scaling had a significant effect on goodness of fit and pRF size estimates. Further, variability in pRF size estimates was directly influenced by stimulus configuration, particularly for higher visual areas including V5/MT+. Finally, we compared eccentricity estimation between phase-encoded and model-based pRF approaches. We observed a tendency for more peripheral eccentricity estimates using phase-encoded methods, independent of stimulus size. We conclude that both eccentricity scaling and polar rather than Cartesian stimulus configuration are important considerations for optimal experimental design in pRF mapping. While all stimulus configurations produce adequate estimates, simultaneous wedge and ring stimulation produced higher fit reliability, with a significant advantage in reduced acquisition time.

Multinomial Bayesian learning for modeling classical and nonclassical receptive field properties.

Science.gov (United States)

Hosoya, Haruo

2012-08-01

We study the interplay of Bayesian inference and natural image learning in a hierarchical vision system, in relation to the response properties of early visual cortex. We particularly focus on a Bayesian network with multinomial variables that can represent discrete feature spaces similar to hypercolumns combining minicolumns, enforce sparsity of activation to learn efficient representations, and explain divisive normalization. We demonstrate that maximal-likelihood learning using sampling-based Bayesian inference gives rise to classical receptive field properties similar to V1 simple cells and V2 cells, while inference performed on the trained network yields nonclassical context-dependent response properties such as cross-orientation suppression and filling in. Comparison with known physiological properties reveals some qualitative and quantitative similarities.

The feature-weighted receptive field: an interpretable encoding model for complex feature spaces.

St-Yves, Ghislain; Naselaris, Thomas

We introduce the feature-weighted receptive field (fwRF), an encoding model designed to balance expressiveness, interpretability and scalability. The fwRF is organized around the notion of a feature map-a transformation of visual stimuli into visual features that preserves the topology of visual space (but not necessarily the native resolution of the stimulus). The key assumption of the fwRF model is that activity in each voxel encodes variation in a spatially localized region across multiple feature maps. This region is fixed for all feature maps; however, the contribution of each feature map to voxel activity is weighted. Thus, the model has two separable sets of parameters: "where" parameters that characterize the location and extent of pooling over visual features, and "what" parameters that characterize tuning to visual features. The "where" parameters are analogous to classical receptive fields, while "what" parameters are analogous to classical tuning functions. By treating these as separable parameters, the fwRF model complexity is independent of the resolution of the underlying feature maps. This makes it possible to estimate models with thousands of high-resolution feature maps from relatively small amounts of data. Once a fwRF model has been estimated from data, spatial pooling and feature tuning can be read-off directly with no (or very little) additional post-processing or in-silico experimentation. We describe an optimization algorithm for estimating fwRF models from data acquired during standard visual neuroimaging experiments. We then demonstrate the model's application to two distinct sets of features: Gabor wavelets and features supplied by a deep convolutional neural network. We show that when Gabor feature maps are used, the fwRF model recovers receptive fields and spatial frequency tuning functions consistent with known organizational principles of the visual cortex. We also show that a fwRF model can be used to regress entire deep

MOBIUS-STRIP-LIKE COLUMNAR FUNCTIONAL CONNECTIONS ARE REVEALED IN SOMATO-SENSORY RECEPTIVE FIELD CENTROIDS.

Directory of Open Access Journals (Sweden)

James Joseph Wright

2014-10-01

Full Text Available Receptive fields of neurons in the forelimb region of areas 3b and 1 of primary somatosensory cortex, in cats and monkeys, were mapped using extracellular recordings obtained sequentially from nearly radial penetrations. Locations of the field centroids indicated the presence of a functional system, in which cortical homotypic representations of the limb surfaces are entwined in three-dimensional Mobius-strip-like patterns of synaptic connections. Boundaries of somatosensory receptive field in nested groups irregularly overlie the centroid order, and are interpreted as arising from the superposition of learned connections upon the embryonic order. Since the theory of embryonic synaptic self-organisation used to model these results was devised and earlier used to explain findings in primary visual cortex, the present findings suggest the theory may be of general application throughout cortex, and may reveal a modular functional synaptic system, which, only in some parts of the cortex, and in some species, is manifest as anatomical ordering into columns.

Local receptive field constrained stacked sparse autoencoder for classification of hyperspectral images.

Science.gov (United States)

Wan, Xiaoqing; Zhao, Chunhui

2017-06-01

As a competitive machine learning algorithm, the stacked sparse autoencoder (SSA) has achieved outstanding popularity in exploiting high-level features for classification of hyperspectral images (HSIs). In general, in the SSA architecture, the nodes between adjacent layers are fully connected and need to be iteratively fine-tuned during the pretraining stage; however, the nodes of previous layers further away may be less likely to have a dense correlation to the given node of subsequent layers. Therefore, to reduce the classification error and increase the learning rate, this paper proposes the general framework of locally connected SSA; that is, the biologically inspired local receptive field (LRF) constrained SSA architecture is employed to simultaneously characterize the local correlations of spectral features and extract high-level feature representations of hyperspectral data. In addition, the appropriate receptive field constraint is concurrently updated by measuring the spatial distances from the neighbor nodes to the corresponding node. Finally, the efficient random forest classifier is cascaded to the last hidden layer of the SSA architecture as a benchmark classifier. Experimental results on two real HSI datasets demonstrate that the proposed hierarchical LRF constrained stacked sparse autoencoder and random forest (SSARF) provides encouraging results with respect to other contrastive methods, for instance, the improvements of overall accuracy in a range of 0.72%-10.87% for the Indian Pines dataset and 0.74%-7.90% for the Kennedy Space Center dataset; moreover, it generates lower running time compared with the result provided by similar SSARF based methodology.

Does attention play a role in dynamic receptive field adaptation to changing acoustic salience in A1?

Fritz, Jonathan B; Elhilali, Mounya; David, Stephen V; Shamma, Shihab A

2007-07-01

Acoustic filter properties of A1 neurons can dynamically adapt to stimulus statistics, classical conditioning, instrumental learning and the changing auditory attentional focus. We have recently developed an experimental paradigm that allows us to view cortical receptive field plasticity on-line as the animal meets different behavioral challenges by attending to salient acoustic cues and changing its cortical filters to enhance performance. We propose that attention is the key trigger that initiates a cascade of events leading to the dynamic receptive field changes that we observe. In our paradigm, ferrets were initially trained, using conditioned avoidance training techniques, to discriminate between background noise stimuli (temporally orthogonal ripple combinations) and foreground tonal target stimuli. They learned to generalize the task for a wide variety of distinct background and foreground target stimuli. We recorded cortical activity in the awake behaving animal and computed on-line spectrotemporal receptive fields (STRFs) of single neurons in A1. We observed clear, predictable task-related changes in STRF shape while the animal performed spectral tasks (including single tone and multi-tone detection, and two-tone discrimination) with different tonal targets. A different set of task-related changes occurred when the animal performed temporal tasks (including gap detection and click-rate discrimination). Distinctive cortical STRF changes may constitute a "task-specific signature". These spectral and temporal changes in cortical filters occur quite rapidly, within 2min of task onset, and fade just as quickly after task completion, or in some cases, persisted for hours. The same cell could multiplex by differentially changing its receptive field in different task conditions. On-line dynamic task-related changes, as well as persistent plastic changes, were observed at a single-unit, multi-unit and population level. Auditory attention is likely to be pivotal in

Callosal Influence on Visual Receptive Fields Has an Ocular, an Orientation-and Direction Bias

Directory of Open Access Journals (Sweden)

2018-04-01

Full Text Available One leading hypothesis on the nature of visual callosal connections (CC is that they replicate features of intrahemispheric lateral connections. However, CC act also in the central part of the binocular visual field. In agreement, early experiments in cats indicated that they provide the ipsilateral eye part of binocular receptive fields (RFs at the vertical midline (Berlucchi and Rizzolatti, 1968, and play a key role in stereoscopic function. But until today callosal inputs to receptive fields activated by one or both eyes were never compared simultaneously, because callosal function has been often studied by cutting or lesioning either corpus callosum or optic chiasm not allowing such a comparison. To investigate the functional contribution of CC in the intact cat visual system we recorded both monocular and binocular neuronal spiking responses and receptive fields in the 17/18 transition zone during reversible deactivation of the contralateral hemisphere. Unexpectedly from many of the previous reports, we observe no change in ocular dominance during CC deactivation. Throughout the transition zone, a majority of RFs shrink, but several also increase in size. RFs are significantly more affected for ipsi- as opposed to contralateral stimulation, but changes are also observed with binocular stimulation. Noteworthy, RF shrinkages are tiny and not correlated to the profound decreases of monocular and binocular firing rates. They depend more on orientation and direction preference than on eccentricity or ocular dominance of the receiving neuron's RF. Our findings confirm that in binocularly viewing mammals, binocular RFs near the midline are constructed via the direct geniculo-cortical pathway. They also support the idea that input from the two eyes complement each other through CC: Rather than linking parts of RFs separated by the vertical meridian, CC convey a modulatory influence, reflecting the feature selectivity of lateral circuits, with a

A self-organizing model of perisaccadic visual receptive field dynamics in primate visual and oculomotor system.

We propose and examine a model for how perisaccadic visual receptive field dynamics, observed in a range of primate brain areas such as LIP, FEF, SC, V3, V3A, V2, and V1, may develop through a biologically plausible process of unsupervised visually guided learning. These dynamics are associated with remapping, which is the phenomenon where receptive fields anticipate the consequences of saccadic eye movements. We find that a neural network model using a local associative synaptic learning rule, when exposed to visual scenes in conjunction with saccades, can account for a range of associated phenomena. In particular, our model demonstrates predictive and pre-saccadic remapping, responsiveness shifts around the time of saccades, and remapping from multiple directions.

Colour Constancy Beyond the Classical Receptive Field.

Science.gov (United States)

Akbarinia, Arash; Parraga, C Alejandro

2017-09-18

The problem of removing illuminant variations to preserve the colours of objects (colour constancy) has already been solved by the human brain using mechanisms that rely largely on centre-surround computations of local contrast. In this paper we adopt some of these biological solutions described by long known physiological findings into a simple, fully automatic, functional model (termed Adaptive Surround Modulation or ASM). In ASM, the size of a visual neuron's receptive field (RF) as well as the relationship with its surround varies according to the local contrast within the stimulus, which in turn determines the nature of the centre-surround normalisation of cortical neurons higher up in the processing chain. We modelled colour constancy by means of two overlapping asymmetric Gaussian kernels whose sizes are adapted based on the contrast of the surround pixels, resembling the change of RF size. We simulated the contrast-dependent surround modulation by weighting the contribution of each Gaussian according to the centre-surround contrast. In the end, we obtained an estimation of the illuminant from the set of the most activated RFs' outputs. Our results on three single-illuminant and one multi-illuminant benchmark datasets show that ASM is highly competitive against the state-of-the-art and it even outperforms learning-based algorithms in one case. Moreover, the robustness of our model is more tangible if we consider that our results were obtained using the same parameters for all datasets, that is, mimicking how the human visual system operates. These results might provide an insight on how dynamical adaptation mechanisms contribute to make object's colours appear constant to us.

The thalamo-cortical auditory receptive fields: regulation by the states of vigilance, learning and the neuromodulatory systems.

Science.gov (United States)

Edeline, Jean-Marc

2003-12-01

The goal of this review is twofold. First, it aims to describe the dynamic regulation that constantly shapes the receptive fields (RFs) and maps in the thalamo-cortical sensory systems of undrugged animals. Second, it aims to discuss several important issues that remain unresolved at the intersection between behavioral neurosciences and sensory physiology. A first section presents the RF modulations observed when an undrugged animal spontaneously shifts from waking to slow-wave sleep or to paradoxical sleep (also called REM sleep). A second section shows that, in contrast with the general changes described in the first section, behavioral training can induce selective effects which favor the stimulus that has acquired significance during learning. A third section reviews the effects triggered by two major neuromodulators of the thalamo-cortical system--acetylcholine and noradrenaline--which are traditionally involved both in the switch of vigilance states and in learning experiences. The conclusion argues that because the receptive fields and maps of an awake animal are continuously modulated from minute to minute, learning-induced sensory plasticity can be viewed as a "crystallization" of the receptive fields and maps in one of the multiple possible states. Studying the interplays between neuromodulators can help understanding the neurobiological foundations of this dynamic regulation.

Effects of wind turbines on UHF television reception: field tests in Denmark

International Nuclear Information System (INIS)

1992-01-01

As a result of a planning application for a windfarm comprising 20 wind turbines at Tynewydd Farm, Gilfach Goch in Mid Glamorgan, a report discussing any detrimental effects the proposal might have on u.h.f. television reception was produced. In order to make the report as definitive as possible, it was decided to carry out field tests on the exact model of wind turbine to be used at Tynewydd. This required a field trip to Denmark, and the opportunity was taken to make measurements on two other models of turbine at the same time. This report presents the analysis of the results for all three turbines. (author)

Chromatic summation and receptive field properties of blue-on and blue-off cells in marmoset lateral geniculate nucleus.

The "blue-on" and "blue-off" receptive fields in retina and dorsal lateral geniculate nucleus (LGN) of diurnal primates combine signals from short-wavelength sensitive (S) cone photoreceptors with signals from medium/long wavelength sensitive (ML) photoreceptors. Three questions about this combination remain unresolved. Firstly, is the combination of S and ML signals in these cells linear or non-linear? Secondly, how does the timing of S and ML inputs to these cells influence their responses? Thirdly, is there spatial antagonism within S and ML subunits of the receptive field of these cells? We measured contrast sensitivity and spatial frequency tuning for four types of drifting sine gratings: S cone isolating, ML cone isolating, achromatic (S + ML), and counterphase chromatic (S - ML), in extracellular recordings from LGN of marmoset monkeys. We found that responses to stimuli which modulate both S and ML cones are well predicted by a linear sum of S and ML signals, followed by a saturating contrast-response relation. Differences in sensitivity and timing (i.e. vector combination) between S and ML inputs are needed to explain the amplitude and phase of responses to achromatic (S + ML) and counterphase chromatic (S - ML) stimuli. Best-fit spatial receptive fields for S and/or ML subunits in most cells (>80%) required antagonistic surrounds, usually in the S subunit. The surrounds were however generally weak and had little influence on spatial tuning. The sensitivity and size of S and ML subunits were correlated on a cell-by-cell basis, adding to evidence that blue-on and blue-off receptive fields are specialised to signal chromatic but not spatial contrast.

Learning to reach by reinforcement learning using a receptive field based function approximation approach with continuous actions.

2009-03-01

Reinforcement learning methods can be used in robotics applications especially for specific target-oriented problems, for example the reward-based recalibration of goal directed actions. To this end still relatively large and continuous state-action spaces need to be efficiently handled. The goal of this paper is, thus, to develop a novel, rather simple method which uses reinforcement learning with function approximation in conjunction with different reward-strategies for solving such problems. For the testing of our method, we use a four degree-of-freedom reaching problem in 3D-space simulated by a two-joint robot arm system with two DOF each. Function approximation is based on 4D, overlapping kernels (receptive fields) and the state-action space contains about 10,000 of these. Different types of reward structures are being compared, for example, reward-on- touching-only against reward-on-approach. Furthermore, forbidden joint configurations are punished. A continuous action space is used. In spite of a rather large number of states and the continuous action space these reward/punishment strategies allow the system to find a good solution usually within about 20 trials. The efficiency of our method demonstrated in this test scenario suggests that it might be possible to use it on a real robot for problems where mixed rewards can be defined in situations where other types of learning might be difficult.

Large developing receptive fields using a distributed and locally reprogrammable address-event receiver.

2010-02-01

A distributed and locally reprogrammable address-event receiver has been designed, in which incoming address-events are monitored simultaneously by all synapses, allowing for arbitrarily large axonal fan-out without reducing channel capacity. Synapses can change the address of their presynaptic neuron, allowing the distributed implementation of a biologically realistic learning rule, with both synapse formation and elimination (synaptic rewiring). Probabilistic synapse formation leads to topographic map development, made possible by a cross-chip current-mode calculation of Euclidean distance. As well as synaptic plasticity in rewiring, synapses change weights using a competitive Hebbian learning rule (spike-timing-dependent plasticity). The weight plasticity allows receptive fields to be modified based on spatio-temporal correlations in the inputs, and the rewiring plasticity allows these modifications to become embedded in the network topology.

Listening is an active process in which attentive focus on salient acoustic features in auditory tasks can influence receptive field properties of cortical neurons. Recent studies showing rapid task-related changes in neuronal spectrotemporal receptive fields (STRFs) in primary auditory cortex of the behaving ferret are reviewed in the context of current research on cortical plasticity. Ferrets were trained on spectral tasks, including tone detection and two-tone discrimination, and on temporal tasks, including gap detection and click-rate discrimination. STRF changes could be measured on-line during task performance and occurred within minutes of task onset. During spectral tasks, there were specific spectral changes (enhanced response to tonal target frequency in tone detection and discrimination, suppressed response to tonal reference frequency in tone discrimination). However, only in the temporal tasks, the STRF was changed along the temporal dimension by sharpening temporal dynamics. In ferrets trained on multiple tasks, distinctive and task-specific STRF changes could be observed in the same cortical neurons in successive behavioral sessions. These results suggest that rapid task-related plasticity is an ongoing process that occurs at a network and single unit level as the animal switches between different tasks and dynamically adapts cortical STRFs in response to changing acoustic demands.

Disinhibition outside receptive fields in the visual cortex.

By definition, the region outside the classical receptive field (CRF) of a neuron in the visual cortex does not directly activate the cell. However, the response of a neuron can be influenced by stimulation of the surrounding area. In previous work, we showed that this influence is mainly suppressive and that it is generally limited to a local region outside the CRF. In the experiments reported here, we investigate the mechanisms of the suppressive effect. Our approach is to find the position of a grating patch that is most effective in suppressing the response of a cell. We then use a masking stimulus at different contrasts over the grating patch in an attempt to disinhibit the response. We find that suppressive effects may be partially or completely reversed by use of the masking stimulus. This disinhibition suggests that effects from outside the CRF may be local. Although they do not necessarily underlie the perceptual analysis of a figure-ground visual scene, they may provide a substrate for this process.

Quality assessment of 3D images encounters more challenges than its 2D counterparts. Directly applying 2D image quality metrics is not the solution. In this paper, we propose a new full-reference quality assessment for stereoscopic images by learning binocular receptive field properties to be more in line with human visual perception. To be more specific, in the training phase, we learn a multiscale dictionary from the training database, so that the latent structure of images can be represented as a set of basis vectors. In the quality estimation phase, we compute sparse feature similarity index based on the estimated sparse coefficient vectors by considering their phase difference and amplitude difference, and compute global luminance similarity index by considering luminance changes. The final quality score is obtained by incorporating binocular combination based on sparse energy and sparse complexity. Experimental results on five public 3D image quality assessment databases demonstrate that in comparison with the most related existing methods, the devised algorithm achieves high consistency with subjective assessment.

2006-01-01

Fertilization is essential in almond production, and pollination can be limiting in production areas. This study investigated stigma receptivity under defined developmental stages to clarify the relationship between stigma morphology, pollen germination, tube growth and fruit set. Light and scanning electron microscopy were employed to examine stigma development at seven stages of flower development ranging from buds that were swollen to flowers in which petals were abscising. Flowers at different stages were hand pollinated and pollen germination and tube growth assessed. Artificial pollinations in the field were conducted to determine the effect of flower age on fruit set. Later stages of flower development exhibited greater stigma receptivity, i.e. higher percentages of pollen germination and more extensive tube growth occurred in older (those opened to the flat petal stage or exhibiting petal fall) than younger flowers. Enhanced stigma receptivity was associated with elongation of stigmatic papillae and increased amounts of stigmatic exudate that inundated papillae at later developmental stages. Field pollinations indicated that the stigma was still receptive and nut set was maintained in older flowers. Stigma receptivity in almond does not become optimal until flowers are past the fully open stage. The stigma is still receptive and fruit set is maintained in flowers even at the stage when petals are abscising. Strategies to enhance pollination and crop yield, including the timing and placement of honey bees, should consider the effectiveness of developmentally advanced flowers.

Effects of wind turbines on UHF television reception: field tests in Denmark, November 1991

1992-01-01

As a result of a planning application for a wind farm comprising 20 wind turbines at Tynewydd Farm, Gilfach Goch in Mid Glamorgan, it became necessary to produce a Report discussing any detrimental effects the proposal might have on UHF television reception. In order to make that Report as definitive as possible, it was decided to carry out field tests on the exact model of wind turbine to be used to Tynewydd. This required a field trip to Denmark, and the opportunity was taken to make measurements on two other models of turbine at the same time. This Report presents the analysis of the results for all three turbines. (Author)

Replicating receptive fields of simple and complex cells in primary visual cortex in a neuronal network model with temporal and population sparseness and reliability.

Tanaka, Takuma; Aoyagi, Toshio; Kaneko, Takeshi

2012-10-01

We propose a new principle for replicating receptive field properties of neurons in the primary visual cortex. We derive a learning rule for a feedforward network, which maintains a low firing rate for the output neurons (resulting in temporal sparseness) and allows only a small subset of the neurons in the network to fire at any given time (resulting in population sparseness). Our learning rule also sets the firing rates of the output neurons at each time step to near-maximum or near-minimum levels, resulting in neuronal reliability. The learning rule is simple enough to be written in spatially and temporally local forms. After the learning stage is performed using input image patches of natural scenes, output neurons in the model network are found to exhibit simple-cell-like receptive field properties. When the output of these simple-cell-like neurons are input to another model layer using the same learning rule, the second-layer output neurons after learning become less sensitive to the phase of gratings than the simple-cell-like input neurons. In particular, some of the second-layer output neurons become completely phase invariant, owing to the convergence of the connections from first-layer neurons with similar orientation selectivity to second-layer neurons in the model network. We examine the parameter dependencies of the receptive field properties of the model neurons after learning and discuss their biological implications. We also show that the localized learning rule is consistent with experimental results concerning neuronal plasticity and can replicate the receptive fields of simple and complex cells.

Differential receptive field organizations give rise to nearly identical neural correlations across three parallel sensory maps in weakly electric fish.

Hofmann, Volker; Chacron, Maurice J

Understanding how neural populations encode sensory information thereby leading to perception and behavior (i.e., the neural code) remains an important problem in neuroscience. When investigating the neural code, one must take into account the fact that neural activities are not independent but are actually correlated with one another. Such correlations are seen ubiquitously and have a strong impact on neural coding. Here we investigated how differences in the antagonistic center-surround receptive field (RF) organization across three parallel sensory maps influence correlations between the activities of electrosensory pyramidal neurons. Using a model based on known anatomical differences in receptive field center size and overlap, we initially predicted large differences in correlated activity across the maps. However, in vivo electrophysiological recordings showed that, contrary to modeling predictions, electrosensory pyramidal neurons across all three segments displayed nearly identical correlations. To explain this surprising result, we incorporated the effects of RF surround in our model. By systematically varying both the RF surround gain and size relative to that of the RF center, we found that multiple RF structures gave rise to similar levels of correlation. In particular, incorporating known physiological differences in RF structure between the three maps in our model gave rise to similar levels of correlation. Our results show that RF center overlap alone does not determine correlations which has important implications for understanding how RF structure influences correlated neural activity.

Acoustic filter properties of A1 neurons can dynamically adapt to stimulus statistics, classical conditioning, instrumental learning and the changing auditory attentional focus.

We propose that attention is the key trigger that in...

Brown, H A; Allison, J D; Samonds, J M; Bonds, A B

2003-01-01

A stimulus located outside the classic receptive field (CRF) of a striate cortical neuron can markedly influence its behavior. To study this phenomenon, we recorded from two cortical sites, recorded and peripheral, with separate electrodes in cats anesthetized with Propofol and nitrous oxide. The receptive fields of each site were discrete (2-7.3 deg between centers). A control orientation tuning (OT) curve was measured for a single recorded cell with a drifting grating. The OT curve was then remeasured while stimulating simultaneously the cell's CRF as well as the peripheral site with a stimulus optimized for that location. For 22/60 cells, the peripheral stimulus suppressed the peak response and/or shifted the center of mass of the OT curve. For 19 of these 22 cells, we then reversibly blocked stimulus-driven activity at the peripheral site by iontophoretic application of GABA (0.5 M). For 6/19 cells, the response returned to control levels, implying that for these cells the inhibitory influence arose from the blocked site. The responses of nine cells remained reduced during inactivation of the peripheral site, suggesting that influence was generated outside the region of local block in area 17. This is consistent with earlier findings suggesting that modulatory influences can originate from higher cortical areas. Three cells had mixed results, suggesting multiple origins of influence. The response of each cell returned to suppressed levels after dissipation of the GABA and returned to baseline values when the peripheral stimulus was removed. These findings support a cortical model in which a cell's response is modulated by an inhibitory network originating from beyond the receptive field that supplants convergence of excitatory lateral geniculate neurons. The existence of cells that exhibit no change in peripherally inhibited responses during the GABA application suggests that peripheral influences may arise from outside area 17, presumably from other cortical

The Two-Dimensional Gabor Function Adapted to Natural Image Statistics: A Model of Simple-Cell Receptive Fields and Sparse Structure in Images.

Science.gov (United States)

Loxley, P N

2017-10-01

The two-dimensional Gabor function is adapted to natural image statistics, leading to a tractable probabilistic generative model that can be used to model simple cell receptive field profiles, or generate basis functions for sparse coding applications. Learning is found to be most pronounced in three Gabor function parameters representing the size and spatial frequency of the two-dimensional Gabor function and characterized by a nonuniform probability distribution with heavy tails. All three parameters are found to be strongly correlated, resulting in a basis of multiscale Gabor functions with similar aspect ratios and size-dependent spatial frequencies. A key finding is that the distribution of receptive-field sizes is scale invariant over a wide range of values, so there is no characteristic receptive field size selected by natural image statistics. The Gabor function aspect ratio is found to be approximately conserved by the learning rules and is therefore not well determined by natural image statistics. This allows for three distinct solutions: a basis of Gabor functions with sharp orientation resolution at the expense of spatial-frequency resolution, a basis of Gabor functions with sharp spatial-frequency resolution at the expense of orientation resolution, or a basis with unit aspect ratio. Arbitrary mixtures of all three cases are also possible. Two parameters controlling the shape of the marginal distributions in a probabilistic generative model fully account for all three solutions. The best-performing probabilistic generative model for sparse coding applications is found to be a gaussian copula with Pareto marginal probability density functions.

Bioinspired magnetic reception and multimodal sensing.

Science.gov (United States)

Taylor, Brian K

2017-08-01

Several animals use Earth's magnetic field in concert with other sensor modes to accomplish navigational tasks ranging from local homing to continental scale migration. However, despite extensive research, animal magnetic reception remains poorly understood. Similarly, the Earth's magnetic field offers a signal that engineered systems can leverage to navigate in environments where man-made positioning systems such as GPS are either unavailable or unreliable. This work uses a behavioral strategy inspired by the migratory behavior of sea turtles to locate a magnetic goal and respond to wind when it is present. Sensing is performed using a number of distributed sensors. Based on existing theoretical biology considerations, data processing is performed using combinations of circles and ellipses to exploit the distributed sensing paradigm. Agent-based simulation results indicate that this approach is capable of using two separate magnetic properties to locate a goal from a variety of initial conditions in both noiseless and noisy sensory environments. The system's ability to locate the goal appears robust to noise at the cost of overall path length.

Reception research 2.0

DEFF Research Database (Denmark)

Mathieu, David

Some might argue that reception analysis is a remnant of the past in an age where “people formerly known as the audience” (Rosen, 2006) are producing and circulating content on a diversity of interactive and participatory media platforms. Far from being the case, reception research must continue......, which appears increasingly complex, multi-formed and integrated to the audience. The original dimensions of Schrøder’s model need to be looked at with reference to both reception and circulation (Jenkins et al., 2013), and to the network that binds participatory media culture. It appears that with media...... 2.0, phenomena which traditionally fell under the labels of interpretation or reception are increasingly taking part in the media text itself.

The media's reception of the risk associated with radioactive disasters

International Nuclear Information System (INIS)

Vettenranta, S.

1996-01-01

There is an urgent need to develop methodologies to examine the response by the media to radioactive disasters. 'Reception study' is a new research approach in the field of mass communication, studying how the viewers construct meaning from TV news. This ongoing reception study explores how fifteen respondents, all involved in the Chernobyl disaster in 1986, recall and interpret TV news coverage nine years after the accident. The main aim is to discover how the news affects the recipients' interpretations of a disaster and what kind of thoughts, reactions and associations risk messages provoke in retrospect, in the present and in the beliefs about the future. The initial findings indicate that the Chernobyl news on TV was mainly based on technical rationality, while viewers construct meaning founded on symbolic, cultural rationality. The transmission of catastrophe news is not just a matter of responding to the information needs of the public. Denotative risk messages simultaneously convey connotative, symbolic resonance of risk on a metaphysical level. (author)

The Anion Paradox in Sodium Taste Reception: Resolution by Voltage-Clamp Studies

Science.gov (United States)

Ye, Qing; Heck, Gerard L.; Desimone, John A.

1991-11-01

Sodium salts are potent taste stimuli, but their effectiveness is markedly dependent on the anion, with chloride yielding the greatest response. The cellular mechanisms that mediate this phenomenon are not known. This "anion paradox" has been resolved by considering the field potential that is generated by restricted electrodiffusion of the anion through paracellular shunts between taste-bud cells. Neural responses to sodium chloride, sodium acetate, and sodium gluconate were studied while the field potential was voltage-clamped. Clamping at electronegative values eliminated the anion effect, whereas clamping at electropositive potentials exaggerated it. Thus, field potentials across the lingual epithelium modulate taste reception, indicating that the functional unit of taste reception includes the taste cell and its paracellular microenvironment.

Eliminating Glutamatergic Input onto Horizontal Cells Changes the Dynamic Range and Receptive Field Organization of Mouse Retinal Ganglion Cells.

In the mammalian retina, horizontal cells receive glutamatergic inputs from many rod and cone photoreceptors and return feedback signals to them, thereby changing photoreceptor glutamate release in a light-dependent manner. Horizontal cells also provide feedforward signals to bipolar cells. It is unclear, however, how horizontal cell signals also affect the temporal, spatial, and contrast tuning in retinal output neurons, the ganglion cells. To study this, we generated a genetically modified mouse line in which we eliminated the light dependency of feedback by deleting glutamate receptors from mouse horizontal cells. This genetic modification allowed us to investigate the impact of horizontal cells on ganglion cell signaling independent of the actual mode of feedback in the outer retina and without pharmacological manipulation of signal transmission. In control and genetically modified mice (both sexes), we recorded the light responses of transient OFF-α retinal ganglion cells in the intact retina. Excitatory postsynaptic currents (EPSCs) were reduced and the cells were tuned to lower temporal frequencies and higher contrasts, presumably because photoreceptor output was attenuated. Moreover, receptive fields of recorded cells showed a significantly altered surround structure. Our data thus suggest that horizontal cells are responsible for adjusting the dynamic range of retinal ganglion cells and, together with amacrine cells, contribute to the center/surround organization of ganglion cell receptive fields in the mouse. SIGNIFICANCE STATEMENT Horizontal cells represent a major neuronal class in the mammalian retina and provide lateral feedback and feedforward signals to photoreceptors and bipolar cells, respectively. The mode of signal transmission remains controversial and, moreover, the contribution of horizontal cells to visual processing is still elusive. To address the question of how horizontal cells affect retinal output signals, we recorded the light

An examination of the concept of driving point receptance

Science.gov (United States)

Sheng, X.; He, Y.; Zhong, T.

2018-04-01

In the field of vibration, driving point receptance is a well-established and widely applied concept. However, as demonstrated in this paper, when a driving point receptance is calculated using the finite element (FE) method with solid elements, it does not converge as the FE mesh becomes finer, suggesting that there is a singularity. Hence, the concept of driving point receptance deserves a rigorous examination. In this paper, it is firstly shown that, for a point harmonic force applied on the surface of an elastic half-space, the Boussinesq formula can be applied to calculate the displacement amplitude of the surface if the response point is sufficiently close to the load. Secondly, by applying the Betti reciprocal theorem, it is shown that the displacement of an elastic body near a point harmonic force can be decomposed into two parts, with the first one being the displacement of an elastic half-space. This decomposition is useful, since it provides a solid basis for the introduction of a contact spring between a wheel and a rail in interaction. However, according to the Boussinesq formula, this decomposition also leads to the conclusion that a driving point receptance is infinite (singular), and would be undefinable. Nevertheless, driving point receptances have been calculated using different methods. Since the singularity identified in this paper was not appreciated, no account was given to the singularity in these calculations. Thus, the validity of these calculation methods must be examined. This constructs the third part of the paper. As the final development of the paper, the above decomposition is utilised to define and determine driving point receptances required for dealing with wheel/rail interactions.

Correlations in V1 are reduced by stimulation outside the receptive field.

Science.gov (United States)

Snyder, Adam C; Morais, Michael J; Kohn, Adam; Smith, Matthew A

2014-08-20

The trial-to-trial response variability of nearby cortical neurons is correlated. These correlations may strongly influence population coding performance. Numerous studies have shown that correlations can be dynamically modified by attention, adaptation, learning, and potent stimulus drive. However, the mechanisms that influence correlation strength remain poorly understood. Here we test whether correlations are influenced by presenting stimuli outside the classical receptive field (RF) of visual neurons, where they recruit a normalization signal termed surround suppression. We recorded simultaneously the activity of dozens of cells using microelectrode arrays implanted in the superficial layers of V1 in anesthetized, paralyzed macaque monkeys. We presented annular stimuli that encircled--but did not impinge upon--the RFs of the recorded cells. We found that these "extra-classical" stimuli reduced correlations in the absence of stimulation of the RF, closely resembling the decorrelating effects of stimulating the RFs directly. Our results suggest that normalization signals may be an important mechanism for modulating correlations. Copyright © 2014 the authors 0270-6474/14/3411222-06$15.00/0.

There is an urgent need to develop methodologies to examine the response by the media to radioactive disasters. `Reception study` is a new research approach in the field of mass communication, studying how the viewers construct meaning from TV news. This ongoing reception study explores how fifteen respondents, all involved in the Chernobyl disaster in 1986, recall and interpret TV news coverage nine years after the accident. The main aim is to discover how the news affects the recipients` interpretations of a disaster and what kind of thoughts, reactions and associations risk messages provoke in retrospect, in the present and in the beliefs about the future. The initial findings indicate that the Chernobyl news on TV was mainly based on technical rationality, while viewers construct meaning founded on symbolic, cultural rationality. The transmission of catastrophe news is not just a matter of responding to the information needs of the public. Denotative risk messages simultaneously convey connotative, symbolic resonance of risk on a metaphysical level. (author).

Full Text Available The paper presents research paradigms which study factors that allow influencing the language development of children with mild intellectual disabilities to the greatest extent possible. Special attention is dedicated to the development of the reception competence with the use of reception didactics methods based on a relatively frequent use of less demanding non-language semiotic functions. The core of the paper presents results of an experimental case study (on a sample of five children with a mild intellectual disability over a one school year period, through which the reception competence in these children was developed with a systematic use of an adapted communication model of literary education as an experimental factor. The results have confirmed the initially set hypothesis about reception progress.

Visual spatial attention concentrates neural resources at the attended location. Recently, we demonstrated that voluntary spatial attention attracts population receptive fields (pRFs) toward its location throughout the visual hierarchy. Theoretically, both a feed forward or feedback mechanism could underlie pRF attraction in a given cortical area. Here, we use sub-millimeter ultra-high field functional MRI to measure pRF attraction across cortical depth and assess the contribution of feed forward and feedback signals to pRF attraction. In line with previous findings, we find consistent attraction of pRFs with voluntary spatial attention in V1. When assessed as a function of cortical depth, we find pRF attraction in every cortical portion (deep, center and superficial), although the attraction is strongest in deep cortical portions (near the gray-white matter boundary). Following the organization of feed forward and feedback processing across V1, we speculate that a mixture of feed forward and feedback processing underlies pRF attraction in V1. Specifically, we propose that feedback processing contributes to the pRF attraction in deep cortical portions. Copyright © 2018. Published by Elsevier Inc.

Bruce X Longwood television reception survey

Property owners living close to a proposed 500-kV transmission line route in Ontario expressed concerns that the line would affect their television reception. To give a reasonable evaluation of the impact of the transmission line, tests were conducted before and after installation of the line in which the possibility of active or passive interference to reception was assessed. Measurements were made of signal strength and ambient noise, and television reception was also recorded on videotape. Possible transmission line effects due to radiated noise, signal reduction, and ghosts are analyzed. The analysis of signal and noise conditions, and the assessment of videotaped reception, provide reasonable evidence that the line has had negligible impact on the television reception along the line route. 13 refs., 18 figs., 12 tabs

Structural Modifications for Torsional Vibration Control of Shafting Systems Based on Torsional Receptances

2016-01-01

Full Text Available Torsional vibration of shafts is a very important problem in engineering, in particular in ship engines and aeroengines. Due to their high levels of integration and complexity, it is hard to get their accurate structural data or accurate modal data. This lack of data is unhelpful to vibration control in the form of structural modifications. Besides, many parts in shaft systems are not allowed to be modified such as rotary inertia of a pump or an engine, which is designed for achieving certain functions. This paper presents a strategy for torsional vibration control of shaft systems in the form of structural modifications based on receptances, which does not need analytical or modal models of the systems under investigation. It only needs the torsional receptances of the system, which can be obtained by testing simple auxiliary structure attached to relevant locations of the shaft system and using the finite element model (FEM of the simple structure. An optimization problem is constructed to determine the required structural modifications, based on the actual requirements of modal frequencies and mode shapes. A numerical experiment is set up and the influence of several system parameters is analysed. Several scenarios of constraints in practice are considered. The numerical simulation results demonstrate the effectiveness of this method and its feasibility in solving torsional vibration problems in practice.

Multi-reception strategy with improved SNR for multichannel MR imaging.

Directory of Open Access Journals (Sweden)

Bing Wu

Full Text Available A multi-reception strategy with extended GRAPPA is proposed in this work to improve MR imaging performance at ultra-high field MR systems with limited receiver channels. In this method, coil elements are separated to two or more groups under appropriate grouping criteria. Those groups are enabled in sequence for imaging first, and then parallel acquisition is performed to compensate for the redundant scan time caused by the multiple receptions. To efficiently reconstruct the data acquired from elements of each group, a specific extended GRAPPA was developed. This approach was evaluated by using a 16-element head array on a 7 Tesla whole-body MRI scanner with 8 receive channels. The in-vivo experiments demonstrate that with the same scan time, the 16-element array with twice receptions and acceleration rate of 2 can achieve significant SNR gain in the periphery area of the brain and keep nearly the same SNR in the center area over an eight-element array, which indicates the proposed multi-reception strategy and extended GRAPPA are feasible to improve image quality for MRI systems with limited receive channels. This study also suggests that it is advantageous for a MR system with N receiver channels to utilize a coil array with more than N elements if an appropriate acquisition strategy is applied.

Blind quality assessment of 3D images encounters more new challenges than its 2D counterparts. In this paper, we propose a blind quality assessment for stereoscopic images by learning the characteristics of receptive fields (RFs) from perspective of dictionary learning, and constructing quality lookups to replace human opinion scores without performance loss. The important feature of the proposed method is that we do not need a large set of samples of distorted stereoscopic images and the corresponding human opinion scores to learn a regression model. To be more specific, in the training phase, we learn local RFs (LRFs) and global RFs (GRFs) from the reference and distorted stereoscopic images, respectively, and construct their corresponding local quality lookups (LQLs) and global quality lookups (GQLs). In the testing phase, blind quality pooling can be easily achieved by searching optimal GRF and LRF indexes from the learnt LQLs and GQLs, and the quality score is obtained by combining the LRF and GRF indexes together. Experimental results on three publicly 3D image quality assessment databases demonstrate that in comparison with the existing methods, the devised algorithm achieves high consistent alignment with subjective assessment.

Compressibility effects on the non-linear receptivity of boundary layers to dielectric barrier discharges

Science.gov (United States)

Denison, Marie F. C.

The reduction of drag and aerodynamic heating caused by boundary layer transition is of central interest for the development of hypersonic vehicles. Receptivity to flow perturbation in the form of Tollmien-Schlichting (TS) wave growth often determines the first stage of the transition process, which can be delayed by depositing specific excitations into the boundary layer. Weakly ionized Dielectric Barrier Discharge (DBD) actuators are being investigated as possible sources of such excitations, but little is known today about their interaction with high-speed flows. In this framework, the first part of the thesis is dedicated to a receptivity study of laminar compressible boundary layers over a flat plate by linear stability analysis following an adjoint operator formulation, under DBD representative excitations assumed independent of flow conditions. The second part of the work concentrates on the development of a coupled plasma-Navier and Stokes solver targeted at the study of supersonic flow and compressibility effects on DBD forcing and non-parallel receptivity. The linear receptivity study of quasi-parallel compressible flows reveals several interesting features such as a significant shift of the region of maximum receptivity deeper into the flow at high Mach number and strong wave amplitude reduction compared to incompressible flows. The response to DBD relevant excitation distributions and to variations of the base flow conditions and system length scales follows these trends. Observed absolute amplitude changes and relative sensitivity modifications between source types are related to the evolution of the offset between forcing peak profile and relevant adjoint mode maximum. The analysis highlights the crucial importance of designing and placing the actuator in a way that matches its force field to the position of maximum boundary layer receptivity for the specific flow conditions of interest.

Embedded Ultrasonic Endoscope, based on embedded microprocessor and embedded real-time operating system, sends a micro ultrasonic probe into coelom through the biopsy channel of the Electronic Endoscope to get the fault histology features of digestive organs by rotary scanning, and acquires the pictures of the alimentary canal mucosal surface. At the same time, ultrasonic signals are processed by signal reception and processing system, forming images of the full histology of the digestive organs. Signal Reception and Processing System is an important component of Embedded Ultrasonic Endoscope. However, the traditional design, using multi-level amplifiers and special digital processing circuits to implement signal reception and processing, is no longer satisfying the standards of high-performance, miniaturization and low power requirements that embedded system requires, and as a result of the high noise that multi-level amplifier brought, the extraction of small signal becomes hard. Therefore, this paper presents a method of signal reception and processing based on double variable gain amplifier and FPGA, increasing the flexibility and dynamic range of the Signal Reception and Processing System, improving system noise level, and reducing power consumption. Finally, we set up the embedded experiment system, using a transducer with the center frequency of 8MHz to scan membrane samples, and display the image of ultrasonic echo reflected by each layer of membrane, with a frame rate of 5Hz, verifying the correctness of the system.

TEACHING COMMUNICATIVE TRANSLATION: AN ACTIVE RECEPTION ANALYSIS BETWEEN THE TRANSLATION AND READER’S RECEPTION

Directory of Open Access Journals (Sweden)

Venny Eka Meidasari

2014-06-01

Full Text Available Literary theory sees reception theory from the reader response that emphasizes the reader’s reception of a literary text. It is generally called audience reception in the analysis of communications models. In literary studies, reception theory originated from the work of Hans-Robert Jauss in the late 1960s. Communication only means that the original message will be clearly sent in its equivalent context to the target receptor. Similarly, the main role of translators is to send the message across without any form of distortion or emphasis. It is delivering the genuine context of the message to the language that the active receptor understands. A single mistake in a context translation can result to offensive message that can eventually lead to misunderstandings between active receptors. This paper proposes on the role of translator as the mediator between a writer of the original text and the active target language receptors of translated version in the course of communication which definitely affects the process and result of translation practice. It also reveals the emphasis on the creation text of the translation theories originated from the strategic communication theories, which hopefully leads to a dream of the most equivalence between the text and the translated version.

Full Text Available From the perspective of cultural studies, in its dialogs with feminist and queer studies, this article analyzes the identification of various publics with Carmen Miranda based on the consumption of her filmic, musical and artistic products, accessing her professional trajectory in its imbrication with its various forms of reception. The focus will be on the negotiations of the artist with her publics, touching on how her career involved reconfigurations concerning aspects of gender, race and sexuality. It is based on a perspective that considers the dynamism of mass culture, considering possibilities for various forms of appropriation of cultural products, as well as shifts and dissonances in receptions. To analyze these aspects, the paper focuses on feminine receptions in Brazil and the United States, and those of a male homosexual public contemporary to her career.

Visual cortex in aging and Alzheimer’s disease: Changes in visual field maps and population receptive fields

Directory of Open Access Journals (Sweden)

Alyssa A. Brewer

2014-02-01

Full Text Available Although several studies have suggested that cortical alterations underlie such age-related visual deficits as decreased acuity, little is known about what changes actually occur in visual cortex during healthy aging. Two recent studies showed changes in primary visual cortex (V1 during normal aging; however, no studies have characterized the effects of aging on visual cortex beyond V1, important measurements both for understanding the aging process and for comparison to changes in age-related diseases. Similarly, there is almost no information about changes in visual cortex in Alzheimer’s disease (AD, the most common form of dementia. Because visual deficits are often reported as one of the first symptoms of AD, measurements of such changes in the visual cortex of AD patients might improve our understanding of how the visual system is affected by neurodegeneration as well as aid early detection, accurate diagnosis and timely treatment of AD. Here we use fMRI to first compare the visual field map (VFM organization and population receptive fields (pRFs between young adults and healthy aging subjects for occipital VFMs V1, V2, V3, and hV4. Healthy aging subjects do not show major VFM organizational deficits, but do have reduced surface area and increased pRF sizes in the foveal representations of V1, V2, and hV4 relative to healthy young control subjects. These measurements are consistent with behavioral deficits seen in healthy aging. We then demonstrate the feasibility and first characterization of these measurements in two patients with mild AD, which reveal potential changes in visual cortex as part of the pathophysiology of AD. Our data aid in our understanding of the changes in the visual processing pathways in normal aging and provide the foundation for future research into earlier and more definitive detection of AD.

Comparison of visual receptive fields in the dorsolateral prefrontal cortex and ventral intraparietal area in macaques.

The concept of receptive field (RF) describes the responsiveness of neurons to sensory space. Neurons in the primate association cortices have long been known to be spatially selective but a detailed characterisation and direct comparison of RFs between frontal and parietal association cortices are missing. We sampled the RFs of a large number of neurons from two interconnected areas of the frontal and parietal lobes, the dorsolateral prefrontal cortex (dlPFC) and ventral intraparietal area (VIP), of rhesus monkeys by systematically presenting a moving bar during passive fixation. We found that more than half of neurons in both areas showed spatial selectivity. Single neurons in both areas could be assigned to five classes according to the spatial response patterns: few non-uniform RFs with multiple discrete response maxima could be dissociated from the vast majority of uniform RFs showing a single maximum; the latter were further classified into full-field and confined foveal, contralateral and ipsilateral RFs. Neurons in dlPFC showed a preference for the contralateral visual space and collectively encoded the contralateral visual hemi-field. In contrast, VIP neurons preferred central locations, predominantly covering the foveal visual space. Putative pyramidal cells with broad-spiking waveforms in PFC had smaller RFs than putative interneurons showing narrow-spiking waveforms, but distributed similarly across the visual field. In VIP, however, both putative pyramidal cells and interneurons had similar RFs at similar eccentricities. We provide a first, thorough characterisation of visual RFs in two reciprocally connected areas of a fronto-parietal cortical network. © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

Language, gay pornography, and audience reception.

Science.gov (United States)

Leap, William L

2011-01-01

Erotic imagery is an important component of gay pornographic cinema, particularly, where work of audience reception is concerned. However, to assume the audience engagement with the films is limited solely to the erotic realm is to underestimate the workings of ideological power in the context and aftermath of reception. For example, the director of the film under discussion here (Men of Israel; Lucas, 2009b) intended to present an erotic celebration of the nation-state. Yet, most viewers ignore the particulars of context in their comments about audience reception, placing the "Israeli" narrative within a broader framework, using transnational rather than film-specific criteria to guide their "reading" of the Israeli-centered narrative. This article uses as its entry point the language that viewers employ when describing their reactions to Men of Israel on a gay video club's Web site; this article shows how the work of audience reception may draw attention to a film's erotic details while invoking social and political messages that completely reframe the film's erotic narrative.

Hebbian learning in a model with dynamic rate-coded neurons: an alternative to the generative model approach for learning receptive fields from natural scenes.

Science.gov (United States)

Hamker, Fred H; Wiltschut, Jan

2007-09-01

Most computational models of coding are based on a generative model according to which the feedback signal aims to reconstruct the visual scene as close as possible. We here explore an alternative model of feedback. It is derived from studies of attention and thus, probably more flexible with respect to attentive processing in higher brain areas. According to this model, feedback implements a gain increase of the feedforward signal. We use a dynamic model with presynaptic inhibition and Hebbian learning to simultaneously learn feedforward and feedback weights. The weights converge to localized, oriented, and bandpass filters similar as the ones found in V1. Due to presynaptic inhibition the model predicts the organization of receptive fields within the feedforward pathway, whereas feedback primarily serves to tune early visual processing according to the needs of the task.

P3-9: Roles of Subthreshold LFP Induced by Receptive Field Surround for Response Modulation in Monkey V1

Directory of Open Access Journals (Sweden)

Kayeon Kim

2012-10-01

Full Text Available A focal stimulus outside the receptive field robustly induces LFP change, while the same stimulus evokes no spike activity. We determined how this subthreshold LFP change interacted with spike response to the RF stimulus. Specifically, we sequentially presented two identical Gabor stimuli with a variable stimulus onset asynchrony (SOA; the first one (S1 was presented outside RF inducing a subthreshold LFP change, and the second one (S2 was subsequently presented within RF generating a spiking response. This enabled us to manipulate the temporal relation between subthreshold LFP and evoked spike activity and to determine whether subthreshold LFP contributed to modulation of spike activity in a SOA-dependent manner. We found that the subthreshold LFP propagated a considerably long distance, estimated to be more than 10 mm of cortical distance. The cross-correlation between the time course of subthreshold LFP and the pattern of SOA-dependency of spike activity was significant. These results indicate that signal integration is farther beyond the RF than previously estimated based on spike-triggered average, and suggest that subthreshold LFP modulate spike activity in a SOA-dependent manner.

Prediction of turning stability using receptance coupling

Science.gov (United States)

Jasiewicz, Marcin; Powałka, Bartosz

2018-01-01

This paper presents an issue of machining stability prediction of dynamic "lathe - workpiece" system evaluated using receptance coupling method. Dynamic properties of the lathe components (the spindle and the tailstock) are assumed to be constant and can be determined experimentally based on the results of the impact test. Hence, the variable of the system "machine tool - holder - workpiece" is the machined part, which can be easily modelled analytically. The method of receptance coupling enables a synthesis of experimental (spindle, tailstock) and analytical (machined part) models, so impact testing of the entire system becomes unnecessary. The paper presents methodology of analytical and experimental models synthesis, evaluation of the stability lobes and experimental validation procedure involving both the determination of the dynamic properties of the system and cutting tests. In the summary the experimental verification results would be presented and discussed.

A decentralized receptance-based damage detection strategy for wireless smart sensors

International Nuclear Information System (INIS)

Jang, Shinae; Spencer Jr, Billie F; Sim, Sung-Han

2012-01-01

Various structural health monitoring strategies have been proposed recently that can be implemented in the decentralized computing environment intrinsic to wireless smart sensor networks (WSSN). Many are based on changes in the experimentally determined flexibility matrix for the structure under consideration. However, the flexibility matrix contains only static information; much richer information is available by considering the dynamic flexibility, or receptance, of the structure. Recently, the stochastic dynamic damage locating vector (SDDLV) method was proposed based on changes of dynamic flexibility matrices employing centrally collected output-only measurements. This paper investigates the potential of the SDDLV method for implementation on a network of wireless smart sensors, where a decentralized, hierarchical, in-network processing approach is used to address issues of scalability of the SDDLV algorithm. Two approaches to aggregate results are proposed that provide robust estimates of damage locations. The efficacy of the developed strategy is first verified using wired sensors emulating a wireless sensor network. Subsequently, the decentralized damage detection strategy is implemented on MEMSIC’s Imote2 smart sensor platform and validated experimentally on a laboratory scale truss bridge. (paper)

From conciliar ecumenism to transformative receptive ecumenism

Full Text Available This article attends to ecumenicity as the second reformation. The ecumenical organisations and agencies hugely influenced the theological praxis and reflection of the church during the past century. The First World Council of Churches (WCC Assembly in Amsterdam, the Netherlands, has been described as the most significant event in church history since the Reformation during the past decade. We saw the emergence of two initiatives that are going to influence ecumenical theology and practice in future, namely the Receptive Ecumenism and Catholic Learning research project, based in Durham, United Kingdom, and the International Theological Colloquium for Transformative Ecumenism of the WCC. Both initiatives constitute a fresh approach in methodology to ecumenical theology and practice. Attention will be given in this article to conciliar ecumenism, receptive ecumenism, transformative ecumenism and its implications for the development of an African transformative receptive ecumenism. In doing so, we should take cognisance of what Küng says about a confessionalist ghetto mentality: ‘We must avoid a confessionalistic ghetto mentality. Instead we should espouse an ecumenical vision that takes into consideration the world religions as well as contemporary ideologies: as much tolerance as possible toward those things outside the Church, toward the religious in general, and the human in general, and the development of that which is specifically Christian belong together!’

Non-cigarette tobacco marketing is less regulated and may promote cigarette smoking among adolescents. We quantified receptivity to advertising for multiple tobacco products and hypothesized associations with susceptibility to cigarette smoking. Wave 1 of the nationally representative PATH (Population Assessment of Tobacco and Health) study interviewed 10 751 adolescents who had never used tobacco. A stratified random selection of 5 advertisements for each of cigarettes, e-cigarettes, smokeless products, and cigars were shown from 959 recent tobacco advertisements. Aided recall was classified as low receptivity, and image-liking or favorite ad as higher receptivity. The main dependent variable was susceptibility to cigarette smoking. Among US youth, 41% of 12 to 13 year olds and half of older adolescents were receptive to at least 1 tobacco advertisement. Across each age group, receptivity to advertising was highest for e-cigarettes (28%-33%) followed by cigarettes (22%-25%), smokeless tobacco (15%-21%), and cigars (8%-13%). E-cigarette ads shown on television had the highest recall. Among cigarette-susceptible adolescents, receptivity to e-cigarette advertising (39.7%; 95% confidence interval [CI]: 37.9%-41.6%) was higher than for cigarette advertising (31.7%; 95% CI: 29.9%-33.6%). Receptivity to advertising for each tobacco product was associated with increased susceptibility to cigarette smoking, with no significant difference across products (similar odds for both cigarette and e-cigarette advertising; adjusted odds ratio = 1.22; 95% CI: 1.09-1.37). A large proportion of US adolescent never tobacco users are receptive to tobacco advertising, with television advertising for e-cigarettes having the highest recall. Receptivity to advertising for each non-cigarette tobacco product was associated with susceptibility to smoke cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

The study of optical illusion is an important method to elucidate the mechanism of visual perception. However, many details about the cause of optical illusions are still unclear. In this research, based on the characteristic of the physiological structure of the retina, we proposed an on-center receptive field model of the retina. Using this model, we simulated the distributions of the inducing field of some visual stimulus. Comparing to the past studies' results, the validity of the proposed model was proofed. Furthermore, we simulated the distributions of the inducing field of some typical illusions. The simulation results can explain these illusion phenomenon rationally. Therefore, it suggested that some of illusions are probably engendered by the distributions of the inducing field in the retina which generated by the illusions stimuli. The practicality of the proposed model was also verified.

Advertisement of fast food on TV may contribute to youth obesity. The goal of the study was to use cued recall to determine whether TV fast-food advertising is associated with youth obesity. A national sample of 2541 U.S. youth, aged 15-23 years, were surveyed in 2010-2011; data were analyzed in 2012. Respondents viewed a random subset of 20 advertisement frames (with brand names removed) selected from national TV fast-food restaurant advertisements (n=535) aired in the previous year. Respondents were asked if they had seen the advertisement, if they liked it, and if they could name the brand. A TV fast-food advertising receptivity score (a measure of exposure and response) was assigned; a 1-point increase was equivalent to affirmative responses to all three queries for two separate advertisements. Adjusted odds of obesity (based on self-reported height and weight), given higher TV fast-food advertising receptivity, are reported. The prevalence of overweight and obesity, weighted to the U.S. population, was 20% and 16%, respectively. Obesity, sugar-sweetened beverage consumption, fast-food restaurant visit frequency, weekday TV time, and TV alcohol advertising receptivity were associated with higher TV fast-food advertising receptivity (median=3.3 [interquartile range: 2.2-4.2]). Only household income, TV time, and TV fast-food advertising receptivity retained multivariate associations with obesity. For every 1-point increase in TV fast-food advertising receptivity score, the odds of obesity increased by 19% (OR=1.19, 95% CI=1.01, 1.40).

Background Advertisement of fast food on TV may contribute to youth obesity. Purpose The goal of the study was to use cued recall to determine whether TV fast-food advertising is associated with youth obesity. Methods A national sample of 2541 U.S. youth, aged 15–23 years, were surveyed in 2010–2011; data were analyzed in 2012. Respondents viewed a random subset of 20 advertisement frames (with brand names removed) selected from national TV fast-food restaurant advertisements (n=535) aired in the previous year. Respondents were asked if they had seen the advertisement, if they liked it, and if they could name the brand. A TV fast-food advertising receptivity score (a measure of exposure and response) was assigned; a 1-point increase was equivalent to affirmative responses to all three queries for two separate advertisements. Adjusted odds of obesity (based on self-reported height and weight), given higher TV fast-food advertising receptivity, are reported. Results The prevalence of overweight and obesity, weighted to the U.S. population, was 20% and 16%, respectively. Obesity, sugar-sweetened beverage consumption, fast-food restaurant visit frequency, weekday TV time, and TV alcohol advertising receptivity were associated with higher TV fast-food advertising receptivity (median=3.3 [interquartile range: 2.2–4.2]). Only household income, TV time, and TV fast-food advertising receptivity retained multivariate associations with obesity. For every 1-point increase in TV fast-food advertising receptivity score, the odds of obesity increased by 19% (OR=1.19, 95% CI=1.01, 1.40). There was no association between receptivity to televised alcohol advertisements or fast-food restaurant visit frequency and obesity. Conclusions Using a cued-recall assessment, TV fast-food advertising receptivity was found to be associated with youth obesity. PMID:24139768

Many animals, including insects, are able to use celestial cues as a reference for spatial orientation and long-distance navigation [1]. In addition to direct sunlight, the chromatic gradient of the sky and its polarization pattern are suited to serve as orientation cues [2-5]. Atmospheric scattering of sunlight causes a regular pattern of E vectors in the sky, which are arranged along concentric circles around the sun [5, 6]. Although certain insects rely predominantly on sky polarization for spatial orientation [7], it has been argued that detection of celestial E vector orientation may not suffice to differentiate between solar and antisolar directions [8, 9]. We show here that polarization-sensitive (POL) neurons in the brain of the desert locust Schistocerca gregaria can overcome this ambiguity. Extracellular recordings from POL units in the central complex and lateral accessory lobes revealed E vector tunings arranged in concentric circles within large receptive fields, matching the sky polarization pattern at certain solar positions. Modeling of neuronal responses under an idealized sky polarization pattern (Rayleigh sky) suggests that these "matched filter" properties allow locusts to unambiguously determine the solar azimuth by relying solely on the sky polarization pattern for compass navigation.

This article focuses on a novel social media-based system that addresses dengue prevention through an integration of three components: predictive surveillance, civic engagement and health education. The aim was to conduct a potential receptivity assessment of this system among smartphone users in the city of Colombo, the epicenter of the dengue epidemic in the island country of Sri Lanka. Grounded in Protection Motivation Theory (PMT) and using a convenience sampling approach, the cross-sectional survey assessed perceived severity (PSe), perceived susceptibility (PSu), perceived response efficacy (PRE), perceived self-efficacy (PSE) and intention-to-use (IU) among 513 individuals. The overall receptivity to the system was high with a score of >4.00 on a five-point scale. Participants belonging to younger, better educated and higher income groups reported significantly better perceptions of the efficaciousness of the system, were confident in their ability to use the system, and planned to use it in the future. PMT variables contributed significantly to regression models predicting IU. We concluded that a social media-based system for dengue prevention will be positively received among Colombo residents and a targeted, strategic health communication effort to raise dengue-related threat perceptions will be needed to encourage greater adoption and use of the system. © The Author 2015.

To measure the receptive risks of malaria in Somalia and compare decisions on intervention scale-up based on this map and the more widely used contemporary risk maps. Cross-sectional community Plasmodium falciparum parasite rate (PfPR) data for the period 2007-2010 corrected to a standard age range of 2 to contemporary (2010) mean PfPR(2-10) and the maximum annual mean PfPR(2-10) (receptive) from the highest predicted PfPR(2-10) value over the study period as an estimate of receptivity. Randomly sampled communities in Somalia. Randomly sampled individuals of all ages. Cartographic descriptions of malaria receptivity and contemporary risks in Somalia at the district level. The contemporary annual PfPR(2-10) map estimated that all districts (n=74) and population (n=8.4 million) in Somalia were under hypoendemic transmission (≤10% PfPR(2-10)). Of these, 23% of the districts, home to 13% of the population, were under transmission of 10%-50% PfPR(2-10)) and the rest as hypoendemic. Compared with maps of receptive risks, contemporary maps of transmission mask disparities of malaria risk necessary to prioritise and sustain future control. As malaria risk declines across Africa, efforts must be invested in measuring receptivity for efficient control planning.

Binocular neurons in parastriate cortex: interocular 'matching' of receptive field properties, eye dominance and strength of silent suppression.

Directory of Open Access Journals (Sweden)

Phillip A Romo

Full Text Available Spike-responses of single binocular neurons were recorded from a distinct part of primary visual cortex, the parastriate cortex (cytoarchitectonic area 18 of anaesthetized and immobilized domestic cats. Functional identification of neurons was based on the ratios of phase-variant (F1 component to the mean firing rate (F0 of their spike-responses to optimized (orientation, direction, spatial and temporal frequencies and size sine-wave-luminance-modulated drifting grating patches presented separately via each eye. In over 95% of neurons, the interocular differences in the phase-sensitivities (differences in F1/F0 spike-response ratios were small (≤ 0.3 and in over 80% of neurons, the interocular differences in preferred orientations were ≤ 10°. The interocular correlations of the direction selectivity indices and optimal spatial frequencies, like those of the phase sensitivies and optimal orientations, were also strong (coefficients of correlation r ≥ 0.7005. By contrast, the interocular correlations of the optimal temporal frequencies, the diameters of summation areas of the excitatory responses and suppression indices were weak (coefficients of correlation r ≤ 0.4585. In cells with high eye dominance indices (HEDI cells, the mean magnitudes of suppressions evoked by stimulation of silent, extra-classical receptive fields via the non-dominant eyes, were significantly greater than those when the stimuli were presented via the dominant eyes. We argue that the well documented 'eye-origin specific' segregation of the lateral geniculate inputs underpinning distinct eye dominance columns in primary visual cortices of mammals with frontally positioned eyes (distinct eye dominance columns, combined with significant interocular differences in the strength of silent suppressive fields, putatively contribute to binocular stereoscopic vision.

This longitudinal study examined the influence of alcohol advertising and promotions on the initiation of alcohol use. A measure of receptivity to alcohol marketing was developed from research about tobacco marketing. Recall and recognition of alcohol brand names were also examined. Data were obtained from in-class surveys of sixth, seventh, and eighth graders at baseline and 12-month follow-up. Participants who were classified as never drinkers at baseline (n = 1,080) comprised the analysis sample. Logistic regression models examined the association of advertising receptivity at baseline with any alcohol use and current drinking at follow-up, adjusting for multiple risk factors, including peer alcohol use, school performance, risk taking, and demographics. At baseline, 29% of never drinkers either owned or wanted to use an alcohol branded promotional item (high receptivity), 12% students named the brand of their favorite alcohol ad (moderate receptivity), and 59% were not receptive to alcohol marketing. Approximately 29% of adolescents reported any alcohol use at follow-up; 13% reported drinking at least 1 or 2 days in the past month. Never drinkers who reported high receptivity to alcohol marketing at baseline were 77% more likely to initiate drinking by follow-up than those were not receptive. Smaller increases in the odds of alcohol use at follow-up were associated with better recall and recognition of alcohol brand names at baseline. Alcohol advertising and promotions are associated with the uptake of drinking. Prevention programs may reduce adolescents' receptivity to alcohol marketing by limiting their exposure to alcohol ads and promotions and by increasing their skepticism about the sponsors' marketing tactics.

A review of recommendations for sequencing receptive and expressive language instruction.

Science.gov (United States)

Petursdottir, Anna Ingeborg; Carr, James E

2011-01-01

We review recommendations for sequencing instruction in receptive and expressive language objectives in early and intensive behavioral intervention (EIBI) programs. Several books recommend completing receptive protocols before introducing corresponding expressive protocols. However, this recommendation has little empirical support, and some evidence exists that the reverse sequence may be more efficient. Alternative recommendations include teaching receptive and expressive skills simultaneously (M. L. Sundberg & Partington, 1998) and building learning histories that lead to acquisition of receptive and expressive skills without direct instruction (Greer & Ross, 2008). Empirical support for these recommendations also is limited. Future research should assess the relative efficiency of receptive-before-expressive, expressive-before-receptive, and simultaneous training with children who have diagnoses of autism spectrum disorders. In addition, further evaluation is needed of the potential benefits of multiple-exemplar training and other variables that may influence the efficiency of receptive and expressive instruction.

Integrated parallel reception, excitation, and shimming (iPRES).

Han, Hui; Song, Allen W; Truong, Trong-Kha

2013-07-01

To develop a new concept for a hardware platform that enables integrated parallel reception, excitation, and shimming. This concept uses a single coil array rather than separate arrays for parallel excitation/reception and B0 shimming. It relies on a novel design that allows a radiofrequency current (for excitation/reception) and a direct current (for B0 shimming) to coexist independently in the same coil. Proof-of-concept B0 shimming experiments were performed with a two-coil array in a phantom, whereas B0 shimming simulations were performed with a 48-coil array in the human brain. Our experiments show that individually optimized direct currents applied in each coil can reduce the B0 root-mean-square error by 62-81% and minimize distortions in echo-planar images. The simulations show that dynamic shimming with the 48-coil integrated parallel reception, excitation, and shimming array can reduce the B0 root-mean-square error in the prefrontal and temporal regions by 66-79% as compared with static second-order spherical harmonic shimming and by 12-23% as compared with dynamic shimming with a 48-coil conventional shim array. Our results demonstrate the feasibility of the integrated parallel reception, excitation, and shimming concept to perform parallel excitation/reception and B0 shimming with a unified coil system as well as its promise for in vivo applications.

Receptivity to Kinetic Fluctuations: A Multiple Scales Approach

Science.gov (United States)

Edwards, Luke; Tumin, Anatoli

2017-11-01

The receptivity of high-speed compressible boundary layers to kinetic fluctuations (KF) is considered within the framework of fluctuating hydrodynamics. The formulation is based on the idea that KF-induced dissipative fluxes may lead to the generation of unstable modes in the boundary layer. Fedorov and Tumin solved the receptivity problem using an asymptotic matching approach which utilized a resonant inner solution in the vicinity of the generation point of the second Mack mode. Here we take a slightly more general approach based on a multiple scales WKB ansatz which requires fewer assumptions about the behavior of the stability spectrum. The approach is modeled after the one taken by Luchini to study low speed incompressible boundary layers over a swept wing. The new framework is used to study examples of high-enthalpy, flat plate boundary layers whose spectra exhibit nuanced behavior near the generation point, such as first mode instabilities and near-neutral evolution over moderate length scales. The configurations considered exhibit supersonic unstable second Mack modes despite the temperature ratio Tw /Te > 1 , contrary to prior expectations. Supported by AFOSR and ONR.

Neuroimaging studies have shed light on cortical language organization, with findings implicating the left and right temporal lobes in speech processing converging to a left-dominant pattern. Findings highlight the fact that the state of theoretical language knowledge is ahead of current clinical language mapping methods, motivating a rethinking of these approaches. The authors used magnetoencephalography and multiple tasks in seven candidates for resective epilepsy surgery to investigate language organization. The authors scanned 12 control subjects to investigate the time course of bilateral receptive speech processes. Laterality indices were calculated for left and right hemisphere late fields ∼150 to 400 milliseconds. The authors report that (1) in healthy adults, speech processes activated superior temporal regions bilaterally converging to a left-dominant pattern, (2) in four of six patients, this was reversed, with bilateral processing converging to a right-dominant pattern, and (3) in three of four of these patients, receptive and expressive language processes were laterally discordant. Results provide evidence that receptive and expressive language may have divergent hemispheric dominance. Right-sided receptive language dominance in epilepsy patients emphasizes the need to assess both receptive and expressive language. Findings indicate that it is critical to use multiple tasks tapping separable aspects of language function to provide sensitive and specific estimates of language localization in surgical patients.

Building Harmony through Religious Reception in Culture: Lesson Learned from Radin Jambat Folktale of Lampung

Directory of Open Access Journals (Sweden)

Agus Iswanto

2018-12-01

Full Text Available Understanding of the existence of various religious receptions in culture gives a great opportunity for the building and nurturance of harmony among religious followers and for the creating of solidarities in the society. This article uncovers receptions of religious aspects (ultimate truth aspect/god, cosmological aspect and religious ritual aspect in the cultural products of Radin Lambat, a folktale from Lampung. The article is based on the texts of Radin Lambat folktale, interviews, and other literary sources about Lampung cultures. Religious receptions as shown in Radin Lambat folktale indicate the preservation of past beliefs, coupled with the gentle addition and inclusion of Islamic teachings, to create harmonization between religion and tradition through folktale. This shows that Islam in the societies of Lampung is Islam that values cultures through the processes of gradual and varied receptions. This article is expected to add evidence to related sources about the concepts and practices of harmony among religious followers in Indonesia in local tradition, and the addition to the range of the rare religious-cultural reception studies of Lampung society

2015-07-01

Cortical inhibitory circuits play important roles in shaping sensory processing. In auditory cortex, however, functional properties of genetically identified inhibitory neurons are poorly characterized. By two-photon imaging-guided recordings, we specifically targeted 2 major types of cortical inhibitory neuron, parvalbumin (PV) and somatostatin (SOM) expressing neurons, in superficial layers of mouse auditory cortex. We found that PV cells exhibited broader tonal receptive fields with lower intensity thresholds and stronger tone-evoked spike responses compared with SOM neurons. The latter exhibited similar frequency selectivity as excitatory neurons. The broader/weaker frequency tuning of PV neurons was attributed to a broader range of synaptic inputs and stronger subthreshold responses elicited, which resulted in a higher efficiency in the conversion of input to output. In addition, onsets of both the input and spike responses of SOM neurons were significantly delayed compared with PV and excitatory cells. Our results suggest that PV and SOM neurons engage in auditory cortical circuits in different manners: while PV neurons may provide broadly tuned feedforward inhibition for a rapid control of ascending inputs to excitatory neurons, the delayed and more selective inhibition from SOM neurons may provide a specific modulation of feedback inputs on their distal dendrites. © The Author 2014.

Transition Prediction in Hypersonic Boundary Layers Using Receptivity and Freestream Spectra

Science.gov (United States)

Balakumar, P.; Chou, Amanda

2016-01-01

Boundary-layer transition in hypersonic flows over a straight cone can be predicted using measured freestream spectra, receptivity, and threshold values for the wall pressure fluctuations at the transition onset points. Simulations are performed for hypersonic boundary-layer flows over a 7-degree half-angle straight cone with varying bluntness at a freestream Mach number of 10. The steady and the unsteady flow fields are obtained by solving the two-dimensional Navier-Stokes equations in axisymmetric coordinates using a 5th-order accurate weighted essentially non-oscillatory (WENO) scheme for space discretization and using a third-order total-variation-diminishing (TVD) Runge-Kutta scheme for time integration. The calculated N-factors at the transition onset location increase gradually with increasing unit Reynolds numbers for flow over a sharp cone and remain almost the same for flow over a blunt cone. The receptivity coefficient increases slightly with increasing unit Reynolds numbers. They are on the order of 4 for a sharp cone and are on the order of 1 for a blunt cone. The location of transition onset predicted from the simulation including the freestream spectrum, receptivity, and the linear and the weakly nonlinear evolutions yields a solution close to the measured onset location for the sharp cone. The simulations over-predict transition onset by about twenty percent for the blunt cone.

Transducer project and optimization of the ultra low magnetic field NMR tomograph reception system system

International Nuclear Information System (INIS)

Vidoto, Edson Luiz Gea

1995-01-01

The aim of the present work was to optimize the signal to noise ratio in our NMR imaging system (TORM 005) by improving transducer's reception quality through better designed coils, balanced tuning circuit for this coils and power decoupling circuits and by reducing interference from the electromagnetic environment. For this purpose, we had to modify the internal electromagnetic shielding and incorporate line filters in the more critical signals paths. Also, new types of coils were developed, improving the signal to noise ratio, and allowing us to make clinical exams with superior quality for several anatomies. Balanced circuits for tuning and matching of the coil were studied and built, allowing a reduction of the coil losses because patient's load. This produced a more reliable coil tuning after positioning each new patient. Circuits to avoid the receiver input overload and decoupling circuits for the isolation of receiver coils from excitation coil were designed and incorporated to the TORM 005. All these alterations of our imaging system (TORM 005) contributed to a significant improvement in the signal to noise ratio, reliability and reproducibility of the system. This permitted to operate the system routinely for clinical applications, research and development in the area of ultra low magnetic field tomography. (author)

2017-10-01

We tested how various measures of e-cigarette advertising exposure and receptivity are related to each other and compare to each other in their associations with e-cigarette use susceptibility and behavior. Cross-sectional data were collected from young adult college students (N = 470; M age = 20.9, SD = 2.1; 65% women). Measures of e-cigarette advertising exposure/receptivity compared included a cued recall measure, measures of marketing receptivity, perceived ad exposure, liking of e-cigarette ads, and frequency of convenience store visit, which is considered a measure of point-of-sale ad exposure. The cued-recall measure was associated with e-cigarette use experimentation but not current e-cigarette use. Marketing receptivity was associated with current e-cigarette use but not e-cigarette use experimentation. Liking of e-cigarette ads was the only measure associated with e-cigarette use susceptibility. Frequency of convenience store visit was associated with current e-cigarette use but not e-cigarette use experimentation or susceptibility. Inclusion of multiple measures of marketing exposure and receptivity is recommended for regulatory research concerning e-cigarette marketing. Marketing receptivity and cued recall measures are strong correlates of current and ever e-cigarette use, respectively.

The routes to be followed into Alberto Caeiros’s poetry: a reception aesthetics approach

Full Text Available The aim of this article is to study the 8th poem Num meio dia de fim de primavera written by Alberto Caeiro. The analysis proposed will be based on some of the Reception Aesthetics concepts mainly focusing on enriching the sensory aspects of the text, especially the visual one. For that purpose, the poetic devices used in the construction of the text as well as its reception by the readers will be highlighted. The analysis will be based on the concepts theorized by Wolfgang Iser. Such concepts are: a the interaction between text and reader and the position of the latter at the time of the former reception; b the blank places; c the negation and negativity structures; and d it will also consider the approach to reading as an act in which the reader is responsible for achieving the meaning for the text and for creating an “aesthetic pleasure” through it. This last concept is grounded in Hans Robert Jauss theory.

Receptivity of Hypersonic Boundary Layers to Distributed Roughness and Acoustic Disturbances

Science.gov (United States)

Balakumar, P.

2013-01-01

Boundary-layer receptivity and stability of Mach 6 flows over smooth and rough seven-degree half-angle sharp-tipped cones are numerically investigated. The receptivity of the boundary layer to slow acoustic disturbances, fast acoustic disturbances, and vortical disturbances is considered. The effects of three-dimensional isolated roughness on the receptivity and stability are also simulated. The results for the smooth cone show that the instability waves are generated in the leading edge region and that the boundary layer is much more receptive to slow acoustic waves than to the fast acoustic waves. Vortical disturbances also generate unstable second modes, however the receptivity coefficients are smaller than that of the slow acoustic wave. Distributed roughness elements located near the nose region decreased the receptivity of the second mode generated by the slow acoustic wave by a small amount. Roughness elements distributed across the continuous spectrum increased the receptivity of the second mode generated by the slow and fast acoustic waves and the vorticity wave. The largest increase occurred for the vorticity wave. Roughness elements distributed across the synchronization point did not change the receptivity of the second modes generated by the acoustic waves. The receptivity of the second mode generated by the vorticity wave increased in this case, but the increase is lower than that occurred with the roughness elements located across the continuous spectrum. The simulations with an isolated roughness element showed that the second mode waves generated by the acoustic disturbances are not influenced by the small roughness element. Due to the interaction, a three-dimensional wave is generated. However, the amplitude is orders of magnitude smaller than the two-dimensional wave.

Full Text Available Background & aims In response to limited research on early language development in infants at high risk for Autism Spectrum Disorder (ASD, the current prospective study examined early expressive and receptive language trajectories in familial high-risk (HR infants who were and were not later diagnosed with ASD (HR-ASD and HR-N, respectively, and low-risk (LR controls with no family history of ASD. Methods Participants were 523 children (371 HR siblings, 56% boys; 152 LR controls, 52% boys followed from age 6 or 12 months to 36 months. Based on independent, best-estimate clinical diagnoses at 36 months, HR participants were classified as HR-ASD (n = 94; 69% boys, or HR-N (n = 277; 52% boys; the sample also included 152 LR controls (52% boys. Expressive and receptive language trajectories were examined based on corresponding domain standard scores on the Mullen Scales of Early Learning ( MSEL at 6, 12, 24, and 36 months. In the combined sample of HR and LR infants, semi-parametric group-based modeling was used to identify distinct trajectories in MSEL standard scores. Results A 3-group solution provided optimal fit to variation in both expressive and receptive language, with the following patterns of scores: (1 inclining from average to above average, (2 stable-average, and (3 declining from average to well below average. For both expressive and receptive language, membership in these trajectories was related to 3-year diagnostic outcomes. Conclusions Although HR-ASD, HR-N, and LR control infants were in each trajectory group, membership in the declining trajectory (expressive and/or receptive was associated with an ASD diagnosis. Implications Evidence of declining trajectories in either expressive or receptive language may be a risk marker for ASD in a high-risk sample.

Results of the study suggest that receptive collocational competence develops alongside EFL learners’ linguistic proficiency; which lends empirical support to Gyllstad (2007, 2009 and Author (2011 among others, who reported similar findings. Furthermore, EFL learners’ collocations growth seems to be quantifiable wherein both linguistic proficiency level and word frequency occupy a crucial role. While more gains in terms of collocations that EFL learners could potentially add as a result of change in proficiency are found at lower levels of proficiency; collocations of words from more frequent word bands seem to be mastered first, and more gains are found at more frequent word bands. These results confirm earlier findings on the non-linearity nature of vocabulary growth (cf. Meara 1996 and the fundamental role played by frequency in word knowledge for vocabulary in general (Nation 1983, 1990, Nation and Beglar 2007, which are extended here to collocations knowledge.

This study examined the relationship between adolescent weight status and food advertisement receptivity. Survey-based evaluation with data collected at baseline (initial and at 2 months), and at follow-up (11 months). New Hampshire and Vermont. Students (n = 2,281) aged 10-13 in 2002-2005. Overweight. Generalized estimating equations to model the relationship between identifying a food advertisement as their favorite and being overweight. Overall, 35.9% of the adolescents were overweight. Less than one fifth named a food advertisement as their favorite (16.1%). Most of the food advertisements were for less-healthful food (89.6%). After controlling for school, age, sex, sociodemographics, physical activity, number of TV sessions watched, and having a TV in the bedroom, overweight adolescents were significantly less likely to be receptive to food advertisements (relative risk = 0.83, 95% confidence interval 0.70, 0.98) compared to non-overweight adolescents. This study provides preliminary evidence that normal-weight adolescents are receptive to unhealthful food advertisements. Longitudinal studies are needed to evaluate whether consistent exposure to advertisements for unhealthful food, particularly if they are promoted with healthful behaviors such as being physically active, influence adolescents' food choices, and ultimately their body mass index, over the long term.

The Early Literary Reception of Ernest Hemingway in Iran

Directory of Open Access Journals (Sweden)

Atefeh Ghasemnejad

2018-01-01

Full Text Available This essay investigates the dynamics that led to the literary reception of Ernest Hemingway before the Islamic Revolution in Iran. This article deploys reception studies as a branch of Comparative Literature with a focus upon conceptions of Siegbert Salomon Prawer and the practical method of George Asselineau to unearth the ideological, political, and historical milieu that embraced Hemingway’s literary fortune in Iran. This investigation, unprecedented in the study of Iranian literature, discusses how and why Hemingway was initially received in Iran. As such, the inception of literary fortune of Ernest Hemingway in Iran is examined by the contextual features, Persian literary taste, and the translator’s incentives that paved the way for this reception. This article also uncovers the reasons for the delay in the literary reception of Hemingway in Iran and discussed why some of Hemingway’s oeuvres enjoyed recognition while others were neglected by the Iranian readership.

Evidence suggests that children present with receptive language skills that are equivalent to or more advanced than expressive language skills. This profile holds true for typical and delayed language development. This study aimed to determine if such a profile existed for preschool children from an area of social deprivation and to investigate if particular language skills influence any differences found between expressive and receptive skills. Data from 187 CELF P2 UK assessments conducted on preschool children from two socially disadvantaged areas in a city in southern Ireland. A significant difference was found between Receptive Language Index (RLI) and Expressive Language Index (ELI) scores with Receptive scores found to be lower than Expressive scores. The majority (78.6%) of participants had a lower Receptive Language than Expressive score (RLI ELI), with very few (3.2%) having the same Receptive and Expressive scores (RLI = ELI). Scores for the Concepts and Following Directions (receptive) sub-test were significantly lower than for the other receptive sub tests, while scores for the Expressive Vocabulary sub-test were significantly higher than for the other expressive sub tests. The finding of more advanced expressive than receptive language skills in socially deprived preschool children is previously unreported and clinically relevant for speech-language pathologists in identifying the needs of this population.

We commend Menninghaus et al. for tackling the role of negative emotions in art reception. However, their model suffers from shortcomings that reduce its applicability to empirical studies of the arts: poor use of evidence, lack of integration with other models, and limited derivation of testable...... hypotheses. We argue that theories about art experiences should be based on empirical evidence....

Learning Peri-saccadic Remapping of Receptive Field from Experience in Lateral Intraparietal Area.

Wang, Xiao; Wu, Yan; Zhang, Mingsha; Wu, Si

2017-01-01

Our eyes move constantly at a frequency of 3-5 times per second. These movements, called saccades, induce the sweeping of visual images on the retina, yet we perceive the world as stable. It has been suggested that the brain achieves this visual stability via predictive remapping of neuronal receptive field (RF). A recent experimental study disclosed details of this remapping process in the lateral intraparietal area (LIP), that is, about the time of the saccade, the neuronal RF expands along the saccadic trajectory temporally, covering the current RF (CRF), the future RF (FRF), and the region the eye will sweep through during the saccade. A cortical wave (CW) model was also proposed, which attributes the RF remapping as a consequence of neural activity propagating in the cortex, triggered jointly by a visual stimulus and the corollary discharge (CD) signal responsible for the saccade. In this study, we investigate how this CW model is learned naturally from visual experiences at the development of the brain. We build a two-layer network, with one layer consisting of LIP neurons and the other superior colliculus (SC) neurons. Initially, neuronal connections are random and non-selective. A saccade will cause a static visual image to sweep through the retina passively, creating the effect of the visual stimulus moving in the opposite direction of the saccade. According to the spiking-time-dependent-plasticity rule, the connection path in the opposite direction of the saccade between LIP neurons and the connection path from SC to LIP are enhanced. Over many such visual experiences, the CW model is developed, which generates the peri-saccadic RF remapping in LIP as observed in the experiment.

Objectives To measure the receptive risks of malaria in Somalia and compare decisions on intervention scale-up based on this map and the more widely used contemporary risk maps. Design Cross-sectional community Plasmodium falciparum parasite rate (PfPR) data for the period 2007–2010 corrected to a standard age range of 2 to Somalia. Participants Randomly sampled individuals of all ages. Main outcome measure Cartographic descriptions of malaria receptivity and contemporary risks in Somalia at the district level. Results The contemporary annual PfPR2–10 map estimated that all districts (n=74) and population (n=8.4 million) in Somalia were under hypoendemic transmission (≤10% PfPR2–10). Of these, 23% of the districts, home to 13% of the population, were under transmission of 10%–50% PfPR2–10) and the rest as hypoendemic. Conclusion Compared with maps of receptive risks, contemporary maps of transmission mask disparities of malaria risk necessary to prioritise and sustain future control. As malaria risk declines across Africa, efforts must be invested in measuring receptivity for efficient control planning. PMID:22855625

Receptivity of Hypersonic Boundary Layers to Acoustic and Vortical Disturbances (Invited)

Balakumar, P.

2015-01-01

Boundary-layer receptivity to two-dimensional acoustic and vortical disturbances for hypersonic flows over two-dimensional and axi-symmetric geometries were numerically investigated. The role of bluntness, wall cooling, and pressure gradients on the receptivity and stability were analyzed and compared with the sharp nose cases. It was found that for flows over sharp nose geometries in adiabatic wall conditions the instability waves are generated in the leading-edge region and that the boundary layer is much more receptive to slow acoustic waves as compared to the fast waves. The computations confirmed the stabilizing effect of nose bluntness and the role of the entropy layer in the delay of boundary layer transition. The receptivity coefficients in flows over blunt bodies are orders of magnitude smaller than that for the sharp cone cases. Wall cooling stabilizes the first mode strongly and destabilizes the second mode. However, the receptivity coefficients are also much smaller compared to the adiabatic case. The adverse pressure gradients increased the unstable second mode regions.

PURPOSE This study assessed African American adolescents’ receptivity to an HIV-prevention curriculum enhanced by text messaging. DESIGN AND METHODS Two focus groups were conducted with 14 African American adolescents regarding how an HIV-prevention curriculum could be enhanced for text messaging delivery. RESULTS The adolescents were receptive to the idea of text messaging HIV-prevention information but wanted to receive a maximum of three messages per day during the hours of 4:00–6:00 p.m. PRACTICE IMPLICATIONS By taking the findings of this study, nurses, other healthcare providers, and community-based organizations can adapt evidence-based interventions for text messaging delivery to individuals at high risk for HIV infection.

The arrival of more than one million migrants, many of them refugees, has proved a major test for the European Union. Although international relief and monitoring agencies have been critical of makeshift camps in Calais and Eidomeni where infectious disease and overcrowding present major health risks, few have examined the nature of the official reception system and its impact on health delivery. Drawing upon research findings from an Economic and Social Research Council (ESRC) funded project, this article considers the physical and mental health of asylum-seekers in transit and analyses how the closure of borders has engendered health risks for populations in recognised reception centres in Sicily and in Greece. Data gathered by means of a survey administered in Greece (300) and in Sicily (400), and complemented by in-depth interviews with migrants (45) and key informants (50) including representatives of government offices, humanitarian and relief agencies, NGOs and activist organisations, are presented to offer an analysis of the reception systems in the two frontline states. We note that medical provision varies significantly from one centre to another and that centre managers play a critical role in the transmission of vital information. A key finding is that, given such disparity, the criteria used by the UNHCR to grade health services reception do not address the substantive issue that prevent refugees from accessing health services, even when provided on site. Health provision is not as recorded in UNHCR reporting but rather there are critical gaps between provision, awareness, and access for refugees in reception systems in Sicily and in Greece. This article concludes that there is a great need for more information campaigns to direct refugees to essential services.

2018-05-15

Correlates of receptive-expressive vocabulary size discrepancies may provide insights into why language development in children with autism spectrum disorder (ASD) deviates from typical language development and ultimately improve intervention outcomes. We indexed receptive-expressive vocabulary size discrepancies of 65 initially preverbal children with ASD (20-48 months) to a comparison sample from the MacArthur-Bates Communicative Development Inventories Wordbank (Frank, Braginsky, Yurovsky, & Marchman, 2017) to quantify typicality. We then tested whether attention toward a speaker and oral motor performance predict typicality of the discrepancy 8 months later. Attention toward a speaker correlated positively with receptive-expressive vocabulary size discrepancy typicality. Imitative and nonimitative oral motor performance were not significant predictors of vocabulary size discrepancy typicality. Secondary analyses indicated that midpoint receptive vocabulary size mediated the association between initial attention toward a speaker and end point receptive-expressive vocabulary size discrepancy typicality. Findings support the hypothesis that variation in attention toward a speaker might partially explain receptive-expressive vocabulary size discrepancy magnitude in children with ASD. Results are consistent with an input-processing deficit explanation of language impairment in this clinical population. Future studies should test whether attention toward a speaker is malleable and causally related to receptive-expressive discrepancies in children with ASD.

First-year university students’ receptive and productive use of academic vocabulary

2016-05-01

Full Text Available The present study explores academic vocabulary knowledge, operationalised through the Academic Word List, among first-year higher education students. Both receptive and productive knowledge and the proportion between the two are examined. Results show that while receptive knowledge is readily acquired by first-year students, productive knowledge lags behind and remains problematic. This entails that receptive knowledge is much larger than productive knowledge, which confirms earlier indications that receptive vocabulary knowledge is larger than productive knowledge for both academic vocabulary (Zhou 2010 and general vocabulary (cf. Laufer 1998, Webb 2008, among others. Furthermore, results reveal that the ratio between receptive and productive knowledge is slightly above 50%, which lends empirical support to previous findings that the ratio between the two aspects of vocabulary knowledge can be anywhere between 50% and 80% (Milton 2009. This finding is extended here to academic vocabulary; complementing Zhou’s (2010 study that investigated the relationship between the two aspects of vocabulary knowledge without examining the ratio between them. On the basis of these results, approaches that could potentially contribute to fostering productive knowledge growth are discussed. Avenues worth exploring to gain further insight into the relationship between receptive and productive knowledge are also suggested.

Advertising Receptivity and Youth Initiation of Smokeless Tobacco.

Science.gov (United States)

Timberlake, David S

2016-07-28

Cross-sectional data suggests that adolescents' receptivity to the advertising of smokeless tobacco is correlated with use of chewing tobacco or snuff. Lack of longitudinal data has precluded determination of whether advertising receptivity precedes or follows initiation of smokeless tobacco. The objective of this study was to test for the association between advertising receptivity and subsequent initiation of smokeless tobacco among adolescent males. Adolescent males from the 1993-1999 Teen Longitudinal California Tobacco Survey were selected at the baseline survey for never having used smokeless tobacco. Separate longitudinal analyses corresponded to two dependent variables, ever use of smokeless tobacco (1993-1996; N = 1,388) and use on 20 or more occasions (1993-1999; N = 1,014). Models were adjusted for demographic variables, risk factors for smokeless tobacco use, and exposure to users of smokeless tobacco. Advertising receptivity at baseline was predictive of ever use by late adolescence (RR(95% CI) = 2.0 (1.5, 2.8)) and regular use by young adulthood (RR(95% CI) = 3.7 (2.1, 6.7)) in models that were adjusted for covariates. Conclusions/ Importance: The findings challenge the tobacco industry's assertion that tobacco marketing does not impact youth initiation. This is particularly relevant to tobacco control in the United States because the 2009 Tobacco Control Act places fewer restrictions on smokeless tobacco products compared to cigarettes.

Longitudinal analysis of receptive vocabulary growth in young Spanish English-speaking children from migrant families.

Jackson, Carla Wood; Schatschneider, Christopher; Leacox, Lindsey

2014-01-01

The authors of this study described developmental trajectories and predicted kindergarten performance of Spanish and English receptive vocabulary acquisition of young Latino/a English language learners (ELLs) from socioeconomically disadvantaged migrant families. In addition, the authors examined the extent to which gender and individual initial performance in Spanish predict receptive vocabulary performance and growth rate. The authors used hierarchical linear modeling of 64 children's receptive vocabulary performance to generate growth trajectories, predict performance at school entry, and examine potential predictors of rate of growth. The timing of testing varied across children. The ELLs (prekindergarten to 2nd grade) participated in 2-5 testing sessions, each 6-12 months apart. The ELLs' average predicted standard score on an English receptive vocabulary at kindergarten was nearly 2 SDs below the mean for monolingual peers. Significant growth in the ELLs' receptive vocabulary was observed between preschool and 2nd grade, indicating that the ELLs were slowly closing the receptive vocabulary gap, although their average score remained below the standard score mean for age-matched monolingual peers. The ELLs demonstrated a significant decrease in Spanish receptive vocabulary standard scores over time. Initial Spanish receptive vocabulary was a significant predictor of growth in English receptive vocabulary. High initial Spanish receptive vocabulary was associated with greater growth in English receptive vocabulary and decelerated growth in Spanish receptive vocabulary. Gender was not a significant predictor of growth in either English or Spanish receptive vocabulary. ELLs from low socioeconomic backgrounds may be expected to perform lower in English compared with their monolingual English peers in kindergarten. Performance in Spanish at school entry may be useful in identifying children who require more intensive instructional support for English vocabulary

The Foucault-Habermas Debate: the Reflexive and Receptive Aspects of Critique

In this paper I discuss the relationship between two different approaches to critical theory – the reflective and the receptive approaches. I show how it can be fruitful to discuss the relationship between Habermas and Foucault through this distinction. My point is that whereas Habermas focusses...... on critique as a reflexive activity, Foucault mainly focusses on the receptive conditions for critique to be possible. I argue further that Foucault focusses on the receptive aspects of critique, the quest for universality is not as pressing as it is in Habermas’ approach, because problematizing critique can...

Full Text Available The new Regulation regarding the reception of construction works and corresponding installations, approved by Government's Decision no. 347/2017 (“Regulation 2017” has general applicability for all construction works for which there is an obligation to obtain a building permit. Regulation 2017 brings significant changes and clarifications expected by the real estate sector regarding: (i the composition of the commissions involved in the reception procedure, (ii the role of the site supervisor who thus gains significant participation in the reception procedure, and (iii the participation of the public authorities' representatives at the reception, having the veto right on the decision of the reception commission upon the completion of the construction works. Another element of novelty brought by Regulation 2017 is the possibility to do the reception upon the completion of the construction works, respectively the final reception for parts / objectives / sectors of or from the building, if they are distinct/ independent from a physical and functional point of view. Thus, the new regulation facilitates the procedure of authorizing investment objectives and the costs of the process. The partial reception is another innovation brought by the Regulation 2017 in support of the investor, who can thus take over a part of the construction, at a certain stage, and obtain its registration with the Land Book.

Adults and children learning a second language show difficulty accessing expressive vocabulary that appears accessible receptively in their first language (L1). We call this discrepancy the receptive-expressive gap.

A generalized linear model for estimating spectrotemporal receptive fields from responses to natural sounds.

Directory of Open Access Journals (Sweden)

Ana Calabrese

2011-01-01

Full Text Available In the auditory system, the stimulus-response properties of single neurons are often described in terms of the spectrotemporal receptive field (STRF, a linear kernel relating the spectrogram of the sound stimulus to the instantaneous firing rate of the neuron. Several algorithms have been used to estimate STRFs from responses to natural stimuli; these algorithms differ in their functional models, cost functions, and regularization methods. Here, we characterize the stimulus-response function of auditory neurons using a generalized linear model (GLM. In this model, each cell's input is described by: 1 a stimulus filter (STRF; and 2 a post-spike filter, which captures dependencies on the neuron's spiking history. The output of the model is given by a series of spike trains rather than instantaneous firing rate, allowing the prediction of spike train responses to novel stimuli. We fit the model by maximum penalized likelihood to the spiking activity of zebra finch auditory midbrain neurons in response to conspecific vocalizations (songs and modulation limited (ml noise. We compare this model to normalized reverse correlation (NRC, the traditional method for STRF estimation, in terms of predictive power and the basic tuning properties of the estimated STRFs. We find that a GLM with a sparse prior predicts novel responses to both stimulus classes significantly better than NRC. Importantly, we find that STRFs from the two models derived from the same responses can differ substantially and that GLM STRFs are more consistent between stimulus classes than NRC STRFs. These results suggest that a GLM with a sparse prior provides a more accurate characterization of spectrotemporal tuning than does the NRC method when responses to complex sounds are studied in these neurons.

Effects of Nose Bluntness on Hypersonic Boundary-Layer Receptivity and Stability Over Cones

Science.gov (United States)

Kara, Kursat; Balakumar, Ponnampalam; Kandil, Osama A.

2011-01-01

The receptivity to freestream acoustic disturbances and the stability properties of hypersonic boundary layers are numerically investigated for boundary-layer flows over a 5 straight cone at a freestream Mach number of 6.0. To compute the shock and the interaction of the shock with the instability waves, the Navier-Stokes equations in axisymmetric coordinates were solved. In the governing equations, inviscid and viscous flux vectors are discretized using a fifth-order accurate weighted-essentially-non-oscillatory scheme. A third-order accurate total-variation-diminishing Runge-Kutta scheme is employed for time integration. After the mean flow field is computed, disturbances are introduced at the upstream end of the computational domain. The appearance of instability waves near the nose region and the receptivity of the boundary layer with respect to slow mode acoustic waves are investigated. Computations confirm the stabilizing effect of nose bluntness and the role of the entropy layer in the delay of boundary-layer transition. The current solutions, compared with experimental observations and other computational results, exhibit good agreement.

Associations linking parenting emotional climate and quality of parental social coaching with young adolescents' receptivity to parental social coaching were examined (N = 80). Parenting emotional climate was assessed with adolescent-reported parental warmth and hostility. Quality of parental social coaching (i.e., prosocial advice, benign framing) was assessed via parent-report and behavioral observations during a parent-adolescent discussion about negative peer evaluation. An adolescent receptivity latent variable score was derived from observations of adolescents' behavior during the discussion, change in adolescents' peer response plan following the discussion, and adolescent-reported tendency to seek social advice from the parent. Parenting climate moderated associations between coaching and receptivity: Higher quality coaching was associated with greater receptivity in the context of a more positive climate. Analyses suggested a stronger association between coaching and receptivity among younger compared to older adolescents. © 2015 The Authors.

The facilitative effect of incorporating echolalia on teaching receptive naming of Chinese characters to children with autism was assessed. In Experiment 1, echoing the requested character name prior to the receptive naming task facilitated matching a character to its name. In addition, task performance was consistently maintained only when echolalia preceded the receptive manual response. Positive results from generalization tests suggested that learned responses occurred across various nove...

Effect of leading-edge geometry on boundary-layer receptivity to freestream sound

Lin, Nay; Reed, Helen L.; Saric, W. S.

1991-01-01

The receptivity to freestream sound of the laminar boundary layer over a semi-infinite flat plate with an elliptic leading edge is simulated numerically. The incompressible flow past the flat plate is computed by solving the full Navier-Stokes equations in general curvilinear coordinates. A finite-difference method which is second-order accurate in space and time is used. Spatial and temporal developments of the Tollmien-Schlichting wave in the boundary layer, due to small-amplitude time-harmonic oscillations of the freestream velocity that closely simulate a sound wave travelling parallel to the plate, are observed. The effect of leading-edge curvature is studied by varying the aspect ratio of the ellipse. The boundary layer over the flat plate with a sharper leading edge is found to be less receptive. The relative contribution of the discontinuity in curvature at the ellipse-flat-plate juncture to receptivity is investigated by smoothing the juncture with a polynomial. Continuous curvature leads to less receptivity. A new geometry of the leading edge, a modified super ellipse, which provides continuous curvature at the juncture with the flat plate, is used to study the effect of continuous curvature and inherent pressure gradient on receptivity.

Receptivity and Forced Response to Acoustic Disturbances in High-Speed Boundary Layers

Science.gov (United States)

Balakumar, P.; King, Rudolph A.; Chou, Amanda; Owens, Lewis R.; Kegerise, Michael A.

2016-01-01

Supersonic boundary-layer receptivity to freestream acoustic disturbances is investigated by solving the Navier-Stokes equations for Mach 3.5 flow over a sharp flat plate and a 7-deg half-angle cone. The freestream disturbances are generated from a wavy wall placed at the nozzle wall. The freestream acoustic disturbances radiated by the wavy wall are obtained by solving the linearized Euler equations. The results for the flat plate show that instability modes are generated at all the incident angles ranging from zero to highly oblique. However, the receptivity coefficient decreases by about 20 times when the incident angle increases from zero to a highly oblique angle of 68 degrees. The results for the cone show that no instability modes are generated when the acoustic disturbances impinge the cone obliquely. The results show that the perturbations generated inside the boundary layer by the acoustic disturbances are the response of the boundary layer to the external forcing. The amplitude of the forced disturbances inside the boundary layer are about 2.5 times larger than the incoming field for zero azimuthal wavenumber and they are about 1.5 times for large azimuthal wavenumbers.

Yun, Soon Gyu; Shin, Jeong Won; Park, Eun Su; Bang, Hae In; Kang, Jung Gu

2016-01-01

Recent advances in laboratory information systems have largely been focused on automation. However, the phlebotomy services have not been completely automated. To address this issue, we introduced an automated reception and turnaround time (TAT) management system, for the first time in Korea, whereby the patient's information is transmitted directly to the actual phlebotomy site and the TAT for each phlebotomy step can be monitored at a glance. The GNT5 system (Energium Co., Ltd., Korea) was installed in June 2013. The automated reception and TAT management system has been in operation since February 2014. Integration of the automated reception machine with the GNT5 allowed for direct transmission of laboratory order information to the GNT5 without involving any manual reception step. We used the mean TAT from reception to actual phlebotomy as the parameter for evaluating the efficiency of our system. Mean TAT decreased from 5:45 min to 2:42 min after operationalization of the system. The mean number of patients in queue decreased from 2.9 to 1.0. Further, the number of cases taking more than five minutes from reception to phlebotomy, defined as the defect rate, decreased from 20.1% to 9.7%. The use of automated reception and TAT management system was associated with a decrease of overall TAT and an improved workflow at the phlebotomy room.

Cat retinal ganglion cell receptive-field alterations after 6-hydroxydopamine induced dopaminergic amacrine cell lesions

International Nuclear Information System (INIS)

Maguire, G.W.; Smith, E.L. III

1985-01-01

Optic tract single-unit recordings were used to study ganglion cell response functions of the intact cat eye after 6-hydroxydopamine (6-OHDA) lesioning of the dopaminergic amacrine cell (AC) population of the inner retina. The impairment of the dopaminergic AC was verified by high pressure-liquid chromatography with electrochemical detection of endogenous dopamine content and by [ 3 H]dopamine high-affinity uptake; the dopaminergic ACs of the treated eyes demonstrated reduced endogenous dopamine content and reduced [ 3 H]dopamine uptake compared with that of their matched controls. Normal appearing [ 3 H]GABA and [ 3 H]-glycine uptake in the treated retinas suggests the absence of any nonspecific action of the 6-OHDA on the neural retina. The impairment of the dopaminergic AC population was found to alter a number of response properties in off-center ganglion cells, but this impairment had only a modest effect on the on-center cells. An abnormally high proportion of the off-center ganglion cells in the 6-OHDA treated eyes possessed nonlinear, Y-type receptive fields. These cells also possessed shift-responses of greater than normal amplitude, altered intensity-response functions, reduced maintained activities, and more transient center responses. Of the on-center type cells, only the Y-type on-center cells were affected by 6-OHDA, possessing higher than normal maintained activities and altered intensity-response functions. The on-center X-cells were unaffected by 6-OHDA treatment. The dopaminergic AC of the photopically adapted cat retina therefore modulates a number of ganglion cell response properties and within the limits of this study is most prominent in off-center ganglion cell circuitry

Difficulties Using Standardized Tests to Identify the Receptive Expressive Gap in Bilingual Children's Vocabularies.

Science.gov (United States)

Gibson, Todd A; Oller, D Kimbrough; Jarmulowicz, Linda

2018-03-01

Receptive standardized vocabulary scores have been found to be much higher than expressive standardized vocabulary scores in children with Spanish as L1, learning L2 (English) in school (Gibson et al., 2012). Here we present evidence suggesting the receptive-expressive gap may be harder to evaluate than previously thought because widely-used standardized tests may not offer comparable normed scores. Furthermore monolingual Spanish-speaking children tested in Mexico and monolingual English-speaking children in the US showed other, yet different statistically significant discrepancies between receptive and expressive scores. Results suggest comparisons across widely used standardized tests in attempts to assess a receptive-expressive gap are precarious.

Simultaneous bilingual language acquisition: The role of parental input on receptive vocabulary development.

Science.gov (United States)

Macleod, Andrea An; Fabiano-Smith, Leah; Boegner-Pagé, Sarah; Fontolliet, Salomé

2013-02-01

Parents often turn to educators and healthcare professionals for advice on how to best support their child's language development. These professionals frequently suggest implementing the 'one-parent-one-language' approach to ensure consistent exposure to both languages. The goal of this study was to understand how language exposure influences the receptive vocabulary development of simultaneous bilingual children. To this end, we targeted nine German-French children growing up in bilingual families. Their exposure to each language within and outside the home was measured, as were their receptive vocabulary abilities in German and French. The results indicate that children are receiving imbalanced exposure to each language. This imbalance is leading to a slowed development of the receptive vocabulary in the minority language, while the majority language is keeping pace with monolingual peers. The one-parent-one-language approach does not appear to support the development of both of the child's languages in the context described in the present study. Bilingual families may need to consider other options for supporting the bilingual language development of their children. As professionals, we need to provide parents with advice that is based on available data and that is flexible with regards to the current and future needs of the child and his family.

Effects of Humor Production, Humor Receptivity, and Physical Attractiveness on Partner Desirability

Directory of Open Access Journals (Sweden)

Michelle Tornquist

2015-10-01

Full Text Available This study examined women’s and men’s preferences for humor production and humor receptivity in long-term and short-term relationships, and how these factors interact with physical attractiveness to influence desirability. Undergraduates viewed photographs of the opposite sex individuals who were high or low in physical attractiveness, along with vignettes varying in humor production and receptivity. Participants rated physical attractiveness and desirability for long-term and short-term relationships. The main findings were that individuals desired partners who were high in humor production and receptivity, though the effects were particularly pronounced for women judging long-term relationships. Moreover, humor production was more important than receptivity for women’s ratings of male desirability. Notably, we also found that ratings of physical attractiveness were influenced by the humor conditions. These results are discussed in terms of the fitness indicator, interest indicator, and encryption hypotheses of the evolutionary functions of humor.

Full Text Available This article aims to offer a broader understanding of the Lithuanian reception of the Warsaw Autumn festival in relation to the modernisation of national music in Lithuania since the late 1950s – early 1960s. Based on a micro-historical and comparative approach to the network of individuals and events, it is intended to explore the shifts of reception through analysis of musical criticism, composers’ work and discourse, and artistic exchange between the Lithuanian and Polish new music scenes. The author discusses the cultural and political factors which affected the changing role of the Warsaw Autumn festival and its impact on the modernisation processes in Lithuanian music. In addition, the asymmetries of mutual understanding and interests between the Polish and Lithuanian music cultures have been highlighted both during the Cold War and the post-communist transformation periods.

Receptivity of Hypersonic Boundary Layers over Straight and Flared Cones

Balakumar, Ponnampalam; Kegerise, Michael A.

2010-01-01

The effects of adverse pressure gradients on the receptivity and stability of hypersonic boundary layers were numerically investigated. Simulations were performed for boundary layer flows over a straight cone and two flared cones. The steady and the unsteady flow fields were obtained by solving the two-dimensional Navier-Stokes equations in axi-symmetric coordinates using the 5th order accurate weighted essentially non-oscillatory (WENO) scheme for space discretization and using third-order total-variation-diminishing (TVD) Runge-Kutta scheme for time integration. The mean boundary layer profiles were analyzed using local stability and non-local parabolized stability equations (PSE) methods. After the most amplified disturbances were identified, two-dimensional plane acoustic waves were introduced at the outer boundary of the computational domain and time accurate simulations were performed. The adverse pressure gradient was found to affect the boundary layer stability in two important ways. Firstly, the frequency of the most amplified second-mode disturbance was increased relative to the zero pressure gradient case. Secondly, the amplification of first- and second-mode disturbances was increased. Although an adverse pressure gradient enhances instability wave growth rates, small nose-tip bluntness was found to delay transition due to the low receptivity coefficient and the resulting weak initial amplitude of the instability waves. The computed and measured amplitude-frequency spectrums in all three cases agree very well in terms of frequency and the shape except for the amplitude.

Knockout mutations of insulin-like peptide genes enhance sexual receptivity in Drosophila virgin females.

Science.gov (United States)

Watanabe, Kazuki; Sakai, Takaomi

2016-01-01

In the fruitfly Drosophila melanogaster, females take the initiative to mate successfully because they decide whether to mate or not. However, little is known about the molecular and neuronal mechanisms regulating sexual receptivity in virgin females. Genetic tools available in Drosophila are useful for identifying molecules and neural circuits involved in the regulation of sexual receptivity. We previously demonstrated that insulin-producing cells (IPCs) in the female brain are critical to the regulation of female sexual receptivity. Ablation and inactivation of IPCs enhance female sexual receptivity, suggesting that neurosecretion from IPCs inhibits female sexual receptivity. IPCs produce and release insulin-like peptides (Ilps) that modulate various biological processes such as metabolism, growth, lifespan and behaviors. Here, we report a novel role of the Ilps in sexual behavior in Drosophila virgin females. Compared with wild-type females, females with knockout mutations of Ilps showed a high mating success rate toward wild-type males, whereas wild-type males courted wild-type and Ilp-knockout females to the same extent. Wild-type receptive females retard their movement during male courtship and this reduced female mobility allows males to copulate. Thus, it was anticipated that knockout mutations of Ilps would reduce general locomotion. However, the locomotor activity in Ilp-knockout females was significantly higher than that in wild-type females. Thus, our findings indicate that the high mating success rate in Ilp-knockout females is caused by their enhanced sexual receptivity, but not by improvement of their sex appeal or by general sluggishness.

Two-dimensional direct numerical simulation (DNS) of the receptivity of a flat-plate boundary layer to temperature spottiness in the Mach 6 free stream is carried out. The influence of spottiness parameters on the receptivity process is studied. It is shown that the temperature spots propagating near the upper boundary-layer edge generate mode F inside the boundary layer. Further downstream mode F is synchronized with unstable mode S (Mack second mode) and excites the latter via the inter-mod...

Contrast normalization contributes to a biologically-plausible model of receptive-field development in primary visual cortex (V1)

Science.gov (United States)

Willmore, Ben D.B.; Bulstrode, Harry; Tolhurst, David J.

2012-01-01

Neuronal populations in the primary visual cortex (V1) of mammals exhibit contrast normalization. Neurons that respond strongly to simple visual stimuli – such as sinusoidal gratings – respond less well to the same stimuli when they are presented as part of a more complex stimulus which also excites other, neighboring neurons. This phenomenon is generally attributed to generalized patterns of inhibitory connections between nearby V1 neurons. The Bienenstock, Cooper and Munro (BCM) rule is a neural network learning rule that, when trained on natural images, produces model neurons which, individually, have many tuning properties in common with real V1 neurons. However, when viewed as a population, a BCM network is very different from V1 – each member of the BCM population tends to respond to the same dominant features of visual input, producing an incomplete, highly redundant code for visual information. Here, we demonstrate that, by adding contrast normalization into the BCM rule, we arrive at a neurally-plausible Hebbian learning rule that can learn an efficient sparse, overcomplete representation that is a better model for stimulus selectivity in V1. This suggests that one role of contrast normalization in V1 is to guide the neonatal development of receptive fields, so that neurons respond to different features of visual input. PMID:22230381

2015-01-01

A long tradition of research including classical rhetoric, esthetics and poetics theory, formalism and structuralism, as well as current perspectives in (neuro)cognitive poetics has investigated structural and functional aspects of literature reception. Despite a wealth of literature published in specialized journals like Poetics, however, still little is known about how the brain processes and creates literary and poetic texts. Still, such stimulus material might be suited better than other genres for demonstrating the complexities with which our brain constructs the world in and around us, because it unifies thought and language, music and imagery in a clear, manageable way, most often with play, pleasure, and emotion (Schrott and Jacobs, 2011). In this paper, I discuss methods and models for investigating the neuronal and cognitive-affective bases of literary reading together with pertinent results from studies on poetics, text processing, emotion, or neuroaesthetics, and outline current challenges and future perspectives.

Thrul, Johannes; Lisha, Nadra E.; Ling, Pamela M.

2016-01-01

Purpose Use of other tobacco products (smokeless tobacco, hookah, cigarillo, e-cigarettes) is increasing, particularly among young adults, and there are few regulations on marketing for these products. We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18-26 years). Methods Time-location sampling was used to collect cross-sectional surveys from 7,540 young adult bar patrons from January 2012 through March of 2014. Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors, and (2) with dual/poly use among current cigarette smokers (n=3,045), controlling for demographics and nicotine dependence. Results Among the entire sample of young adult bar patrons (Mage=23.7, SD=1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.49, 95% confidence interval [CI] 1.90-3.27, pmarketing receptivity was significantly associated with use of smokeless tobacco (AOR=1.44, 95% CI 1.05-1.98, pmarketing receptivity.

Genetic and non-genetic factors affecting rabbit doe sexual receptivity as estimated from one generation of divergent selection

Directory of Open Access Journals (Sweden)

2015-09-01

Full Text Available Sexual receptivity of rabbit does at insemination greatly influences fertility and is generally induced by hormones or techniques known as “biostimulation”. Searching for more sustainable farming systems, an original alternative would be to utilise the genetic pathway to increase the does’receptivity. The purpose of the present study was to identify genetic and non-genetic factors that influence rabbit doe sexual receptivity, in the context of a divergent selection experiment over 1 generation. The experiment spanned 2 generations: the founder generation (G0 consisting of 140 rabbit does, and the G1 generation comprising 2 divergently selected lines (L and H lines with 70 does each and 2 successive batches from each generation. The selection rate of the G0 females to form the G1 lines was 24/140. The selection tests consisted of 16 to 18 successive receptivity tests at the rate of 3 tests per week. On the basis of 4716 tests from 275 females, the average receptivity was 56.6±48.2%. A batch effect and a test operator effect were revealed. The contribution of females to the total variance was 20.0%, whereas that of bucks was only 1.1%. Throughout the experiment, 18.2% of does expressed a low receptivity (< 34%, 50.7% a medium one and 33.1% a high one (>66%. Some does were frequently receptive, whereas others were rarely receptive. The repeatability of sexual receptivity was approximately 20%. The results confirmed the high variability of sexual receptivity of non-lactating rabbit does maintained without any biostimulation or hormonal treatment. A lack of selection response on receptivity was observed. Accordingly, the heritability of receptivity was estimated at 0.01±0.02 from an animal model and at 0.02±0.03 from a  sire and dam model. The heritability of the average receptivity of a doe was calculated as 0.04. In agreement with the low estimated heritability, the heritability determined was no different from zero

Endometrial Receptivity Profile in Patients with Premature Progesterone Elevation on the Day of hCG Administration

Directory of Open Access Journals (Sweden)

Delphine Haouzi

2014-01-01

Full Text Available The impact of a premature elevation of serum progesterone level, the day of hCG administration in patients under controlled ovarian stimulation during IVF procedure, on human endometrial receptivity is still debated. In the present study, we investigated the endometrial gene expression profile shifts during the prereceptive and receptive secretory stage in patients with normal and elevated serum progesterone level on the day of hCG administration in fifteen patients under stimulated cycles. Then, specific biomarkers of endometrial receptivity in these two groups of patients were tested. Endometrial biopsies were performed on oocyte retrieval day and on day 3 of embryo transfer, respectively, for each patient. Samples were analysed using DNA microarrays and qRT-PCR. The endometrial gene expression shift from the prereceptive to the receptive stage was altered in patients with high serum progesterone level (>1.5 ng/mL on hCG day, suggesting accelerated endometrial maturation during the periovulation period. This was confirmed by the functional annotation of the differentially expressed genes as it showed downregulation of cell cycle-related genes. Conversely, the profile of endometrial receptivity was comparable in both groups. Premature progesterone rise alters the endometrial gene expression shift between the prereceptive and the receptive stage but does not affect endometrial receptivity.

Discriminative ability of reflex receptive fields to distinguish patients with acute and chronic low back pain.

Low back pain has a life time prevalence of 70% to 85%. Approximately 10% to 20% of all patients experience recurrent episodes or develop chronic low back pain. Sociodemographic, clinical, and psychological characteristics explain the transition from acute to chronic low back pain only to a limited extent. Altered central pain processing may be a contributing mechanism. The measurement of reflex receptive fields (RRF) is a novel method to assess altered central pain processing. The RRF area denotes the area of the foot sole from which spinal nociceptive reflexes can be elicited. It was shown to be enlarged in patients with acute and chronic low back pain compared with pain-free individuals. The aim of the study was to explore the discriminative ability of the RRF to distinguish patients with acute and chronic low back pain with the hypothesis that enlarged RRF are associated with chronic low back pain. We included 214 patients with either acute or chronic low back pain and compared RRF between groups in both univariable and multivariable analyses adjusted for different sociodemographic and clinical characteristics possibly associated with the transition to chronic pain. We found a mean difference between patients with acute and chronic low back pain of -0.01 (95% confidence interval [CI], -0.06 to 0.04) in the crude, -0.02 (95% CI, -0.08 to 0.04) in the age and sex adjusted, and -0.02 (95% CI, -0.09 to 0.05) in the fully adjusted model. Our results suggest that the enlargement of RRF area may not be associated with the transition from acute to chronic low back pain.

Full Text Available Reading is a process of aesthetically appreciative receptive to emphasize critical-creative reading activities. Metacognitively students understand, address any and explore the idea of the author in the text. Students responded, criticize, and evaluate the author's ideas in the text. At this stage, students can construct their post read text into other forms (new text. The aim of this strategy equips students to understand the meaning of the story, explore ideas, responding critically, and creatively pouring backstory idea. Reading strategies aesthetically-critical-creative receptive grabbed cognitive, effective, and psychomotor toward literacy critical reading and creative writing. Read appreciative included into the activities of reading comprehension. This activity involves the sensitivity and ability to process aesthetically-receptive reading and critical-creative. Readers imagination roam the author to obtain meaningful understanding and experience of reading. Some models of reading comprehension proposed experts covering the steps before reading, when reading, and after reading. At that stage to enable students after reading thinking abilities. Activities that can be done at this stage, for example, examine the back story, retell, make drawings, diagrams, or maps the concept of reading, as well as making a road map that describes the event. Other activities that can be done is to transform our student's text stories through reinforcement form illustrated stories into comic book form, for example (transliteration.

Characterization of a Laser-Generated Perturbation in High-Speed Flow for Receptivity Studies

Chou, Amanda; Schneider, Steven P.; Kegerise, Michael A.

2014-01-01

A better understanding of receptivity can contribute to the development of an amplitude-based method of transition prediction. This type of prediction model would incorporate more physics than the semi-empirical methods, which are widely used. The experimental study of receptivity requires a characterization of the external disturbances and a study of their effect on the boundary layer instabilities. Characterization measurements for a laser-generated perturbation were made in two different wind tunnels. These measurements were made with hot-wire probes, optical techniques, and pressure transducer probes. Existing methods all have their limitations, so better measurements will require the development of new instrumentation. Nevertheless, the freestream laser-generated perturbation has been shown to be about 6 mm in diameter at a static density of about 0.045 kg/cubic m. The amplitude of the perturbation is large, which may be unsuitable for the study of linear growth.

To compare the effects of 1) active group music therapy and 2) receptive group music therapy to group counseling in treatment of major depressive disorder (MDD). On top of standard care, 14 MDD outpatients were randomly assigned to receive 1) active group music therapy (n=5), 2) receptive group music therapy (n=5), or 3) group counseling (n=4). There were 12 one-hour weekly group sessions in each arm. Participants were assessed at baseline, 1 month (after 4 sessions), 3 months (end of interventions), and 6 months. Primary outcomes were depressive scores measured by Montgomery-Åsberg Depression Rating Scale (MADRS) Thai version. Secondary outcomes were self-rated depression score and quality of life. At 1 month, 3 months, and 6 months, both therapy groups showed statistically non-significant reduction in MADRS Thai scores when compared with the control group (group counseling). The reduction was slightly greater in the active group than the receptive group. Although there were trend toward better outcomes on self-report depression and quality of life, the differences were not statistically significant. Group music therapy, either active or receptive, is an interesting adjunctive treatment option for outpatients with MDD. The receptive group may reach peak therapeutic effect faster, but the active group may have higher peak effect. Group music therapy deserves further comprehensive studies.

Thrul, Johannes; Lisha, Nadra E; Ling, Pamela M

2016-12-01

Use of other tobacco products (smokeless tobacco, hookah, cigarillo, and e-cigarettes) is increasing, particularly among young adults, and there are few regulations on marketing for these products. We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18-26 years). Time-location sampling was used to collect cross-sectional surveys from 7,540 young adult bar patrons from January 2012 through March of 2014. Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors and (2) with dual/poly use among current cigarette smokers (n = 3,045), controlling for demographics and nicotine dependence. Among the entire sample of young adult bar patrons (Mean age  = 23.7, standard deviation = 1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.56, 95% confidence interval [CI] 2.08-3.16, p marketing receptivity was significantly associated with use of smokeless tobacco (AOR = 1.63, 95% CI 1.22-2.18, p marketing receptivity.

2013-12-01

Full Text Available K-pop’s popularity and its participatory fan culture have expanded beyond Asia and become significant in Europe in the past few years. After South Korean pop singer Psy’s “Gangnam Style” music video topped the Austrian chart in October 2012, the number and size of K-pop events in Austria sharply increased, with fans organizing various participatory events, including K-pop auditions, dance festivals, club meetings, quiz competitions, dance workshops, and smaller fan-culture gatherings. In the private sector, longtime fans have transitioned from participants to providers, and in the public sector, from observers to sponsors. Through in-depth interviews with event organizers, sponsors, and fans, this article offers an ethnographic study of the reception of K-pop in Europe that takes into consideration local interactions between fans and Korean sponsors, perspectives on the genre, patterns of social integration, and histories. As a case study, this research stresses the local situatedness of K-pop fan culture by arguing that local private and public sponsors and fans make the reception of K-pop different in each locality. By exploring local scenes of K-pop reception and fan culture, the article demonstrates the rapidly growing consumption of K-pop among Europeans and stresses multidirectional understandings of globalization.

Olfactory bulb deprivation increased sexual receptivity in 4-day cyclic female rats on the late afternoon of prooestrus (6-7, p.m.). The proportion of receptive females was higher in bulbectomized (B) than in sham operated (SH) animals. On the contrary the same proportion of B and SH females mated in the evening of prooestrus (10. 30-11. 30 p.m.). An increased lordosis quotient was observed in the B females at either of these two stages of the cycle.

To test the capacity of a sentence verification (SV) task to reliably activate receptive language areas. Presurgical evaluation of language is useful in predicting postsurgical deficits in patients who are candidates for neurosurgery. Productive language tasks have been successfully elaborated, but more conflicting results have been found in receptive language mapping. Twenty-two right-handed healthy controls made true-false semantic judgements of brief sentences presented auditorily. Group maps showed reliable functional activations in the frontal and temporoparietal language areas. At the individual level, the SV task showed activation located in receptive language areas in 100% of the participants with strong left-sided distributions (mean lateralisation index of 69.27). The SV task can be considered a useful tool in evaluating receptive language function in individual subjects. This study is a first step towards designing the fMRI task which may serve to presurgically map receptive language functions. (orig.)

Non-invasive assessment of hemispheric dominance for receptive language using magnetoencephalography (MEG) is now a well-established procedure used across several epilepsy centers in the context of pre-surgical evaluation of children and adults while awake, alert and attentive. However, the utility of MEG for the same purpose, in cases of sedated patients, is contested. Establishment of the efficiency of MEG is especially important in the case of children who, for a number of reasons, must be assessed under sedation. Here we explored the efficacy of MEG language mapping under sedation through retrospective review of 95 consecutive pediatric patients, who underwent our receptive language test as part of routine clinical evaluation. Localization of receptive language cortex and subsequent determination of laterality was successfully completed in 78% (n = 36) and 55% (n = 27) of non-sedated and sedated patients, respectively. Moreover, the proportion of patients deemed left hemisphere dominant for receptive language did not differ between non-sedated and sedated patients, exceeding 90% in both groups. Considering the challenges associated with assessing brain function in pediatric patients, the success of passive MEG in the context of the cases reviewed in this study support the utility of this method in pre-surgical receptive language mapping.

We studied the duration of the drop of specific (3)H-flunitrazepam binding by synaptosomal membranes from the brain of C57Bl/6 and BALB/c mice after open-field and "contact with predator" tests. It was found that reduced benzodiazepine reception in BALB/c mice after open-field test persisted for 1.5 h, but no changes of this parameter were found in C57Bl/6 mice. After contact with predator, the binding capacity of the benzodiazepine site of GABAA receptor was reduced for 8 h in BALB/c mice and for 24 h in C57Bl/6 mice.

A Mobile System for Music Anamnesis and Receptive Music Therapy in the Personal Home.

Receptive music therapy is active hearing of music that is specifically selected to cause a certain effect on a person, such as pain reduction, mental opening, confrontation etc. This active, guided hearing could be helpful as a supporting ritual for patients at home and could extend traditional therapy. However, patients are often unable to select the music pieces that might be helpful for them in a current situation. We are suggesting a self-learning decision support system that allows a patient to answer questions on music anamnesis, is ready for inclusion into an electronic health record, and which enables a therapist to compile a therapeutic music program for the patient at home. Beyond this, the system also suggests appropriate music and duration of listening based on the patient's reported current mental state. In this paper, a concept for such a mobile system for receptive music therapy will be proposed.

Membrane–initiated estradiol signaling regulating sexual receptivity

2011-09-01

Full Text Available Estradiol has profound actions on the structure and function of the nervous system. In addition to nuclear actions that directly modulate gene expression, the idea that estradiol can rapidly activate cell signaling by binding to membrane estrogen receptors (mERs has emerged. Even the regulation of sexual receptivity, an action previously thought to be completely regulated by nuclear ERs, has been shown to have a membrane-initiated estradiol signaling (MIES component. This highlighted the question of the nature of mERs. Several candidates have been proposed, ERα, ERβ, ER-X, GPR30 (G protein coupled estrogen receptor; GPER, and a receptor activated by a diphenylacrylamide compound, STX. Although each of these receptors has been shown to be active in specific assays, we present evidence for and against their participation in sexual receptivity by acting in the lordosis-regulating circuit. The initial MIES that activates the circuit is in the arcuate nucleus of the hypothalamus (ARH. Using both activation of μ-opioid receptors (MOR in the medial preoptic nucleus and lordosis behavior, we document that both ERα and the STX receptor participate in the required MIES. ERα and the STX receptor activation of cell signaling are dependent on the transactivation of type 1 metabotropic glutamate receptors (mGluR1a that augment progesterone synthesis in astrocytes and protein kinase C (PKC in ARH neurons. While estradiol-induced sexual receptivity does not depend on neuroprogesterone, proceptive behaviors do. Moreover, the ERα and the STX receptor activation of medial preoptic MORs and augmentation of lordosis were sensitive to mGluR1a blockade. These observations suggest a common mechanism through which mERs are coupled to intracellular signaling cascades, not just in regulating reproduction, but in actions throughout the neuraxis including the cortex, hippocampus, striatum and DRGs.

Endometrial Receptivity and its Predictive Value for IVF/ICSI-Outcome.

Science.gov (United States)

Heger, A; Sator, M; Pietrowski, D

2012-08-01

Endometrial receptivity plays a crucial role in the establishment of a healthy pregnancy in cycles of assisted reproduction. The endometrium as a key factor during reproduction can be assessed in multiple ways, most commonly through transvaginal grey-scale or 3-D ultrasound. It has been shown that controlled ovarian hyperstimulation has a great impact on the uterine lining, which leads to different study results for the predictive value of endometrial factors measured on different cycle days. There is no clear consensus on whether endometrial factors are appropriate to predict treatment outcome and if so, which one is suited best. The aim of this review is to summarize recent findings of studies about the influence of endometrial thickness, volume and pattern on IVF- and ICSI-treatment outcome and provide an overview of future developments in the field.

Full Text Available The research “Transfer and Reception of New Institutional Economics: An Example of Two Universities in Serbia” was conducted in 2005/2006. In order to achieve the goals of the Serbian team of the DIOSCURI project, the main aim of the case study is analysis of the influence of Western institutions in the light of transfer and reception of new institutional economics in two academic institutions in Serbia: The Faculty of Law (The Department of Law and Economics of the University of Belgrade, and The Faculty of Management of BK University. The title of the case study illustrates the focus of the entire research: analysis of Western influence, namely transfer and reception of new institutional economics, on the two institutions and possible obstacles caused by old-fashioned stakeholders and informal institutions. Bearing in mind that the Department of Law and Economics is the leader in the reception of the new institutional economics (NIE in Serbia, the case study will be mostly about it. The Faculty of Management was chosen because of its “greenfield” character and the fact that from its very beginning it followed the experiences of North American universities. The research investigates whether and how the transfer and reception of the Western ideas and economic theory, particularly the NIE, is affected by the difference between an institution with a two-hundred-year tradition and a newly established one. The question is how a traditionalist institution like the Faculty of Law communicated Western economic thought and whether endurance in teaching the exclusively Marxian paradigm up until the 1990s, was an obstacle to the reception of Western economic thought, particularly NIE.

To compare the comprehension of depressed and non-depressed male and female Iranian learners of English as a Foreign Language (EFL) in receptive skills, and to investigate whether inefficiency in learning English could be due to depression. We selected 126 boys and 96 girls aged between 15 and 18 by simple random sampling from 2 high schools in Kerman, Iran to examine whether there was any significant relationship between depression and comprehension of receptive skills in males and females. We undertook this descriptive, correlational study between January and May 2011 in Kerman, Iran. After administration of the Beck Depression Inventory (BDI), we found that 93 students were non-depressed, 65 had minimal depression, 48 mild depression, and 16 suffered from severe depression. The correlation between participants` scores on listening and reading test with depression level indicated a significant relationship between depression and comprehension of both listening, and reading. Males had higher scores in both reading and listening. In listening, there was no significant difference among the levels of depression and males and females. Regarding the reading skill, there was no significant difference among levels of depression; however, the reading comprehension of males and females differed significantly. Learners who show a deficiency in receptive skills should be examined for the possibility of suffering from some degree of depression.

More Gamma More Predictions: Gamma-Synchronization as a Key Mechanism for Efficient Integration of Classical Receptive Field Inputs with Surround Predictions

Science.gov (United States)

Vinck, Martin; Bosman, Conrado A.

2016-01-01

During visual stimulation, neurons in visual cortex often exhibit rhythmic and synchronous firing in the gamma-frequency (30–90 Hz) band. Whether this phenomenon plays a functional role during visual processing is not fully clear and remains heavily debated. In this article, we explore the function of gamma-synchronization in the context of predictive and efficient coding theories. These theories hold that sensory neurons utilize the statistical regularities in the natural world in order to improve the efficiency of the neural code, and to optimize the inference of the stimulus causes of the sensory data. In visual cortex, this relies on the integration of classical receptive field (CRF) data with predictions from the surround. Here we outline two main hypotheses about gamma-synchronization in visual cortex. First, we hypothesize that the precision of gamma-synchronization reflects the extent to which CRF data can be accurately predicted by the surround. Second, we hypothesize that different cortical columns synchronize to the extent that they accurately predict each other’s CRF visual input. We argue that these two hypotheses can account for a large number of empirical observations made on the stimulus dependencies of gamma-synchronization. Furthermore, we show that they are consistent with the known laminar dependencies of gamma-synchronization and the spatial profile of intercolumnar gamma-synchronization, as well as the dependence of gamma-synchronization on experience and development. Based on our two main hypotheses, we outline two additional hypotheses. First, we hypothesize that the precision of gamma-synchronization shows, in general, a negative dependence on RF size. In support, we review evidence showing that gamma-synchronization decreases in strength along the visual hierarchy, and tends to be more prominent in species with small V1 RFs. Second, we hypothesize that gamma-synchronized network dynamics facilitate the emergence of spiking output that

”Savage Spain”? On the reception of Spanish art in Britain and Ireland

Full Text Available Review of: Nigel Glendinning and Hilary Macartney, eds, Spanish Art in Britain and Ireland, 1750–1920: Studies in Reception in Memory of Enriqueta Harris Frankfort, Woodbridge: Tamesis, 2010. This review evaluates the first scholarly study exclusively dedicated to the reception history of Spanish art in Britain and Ireland, 1750–1920. Progressing systematically through the different chapters, it highlights the various responses and perspectives that are addressed in the book. Issues of taste and collecting are examined, followed by historiographical concerns such as the methods and techniques of writing, illustrating and reproducing Spanish art in the nineteenth century. Shifting attitudes towards Spain and Spanish art are also explored, as are the roles of prominent figures in disseminating knowledge and appreciation of Spanish art, notably Sir William Stirling Maxwell and Richard Ford. Finally, the review outlines the critical fortunes of Spain’s foremost artists: Murillo, Velázquez, Ribera, Zurbarán and Goya. It ends by suggesting how this study could be expanded methodologically, considering the reception history of Spanish art in the light of important literature on reception theory and aesthetics.

Sterile cultured isolates of lichen-forming aposymbionts have not yet been used to investigate lichen-rock interactions under controlled conditions. In this study mycobionts and photobiont of the endolithic lichens Bagliettoa baldensis and Bagliettoa marmorea were isolated and inoculated with coupons of one limestone and four marbles commonly employed in the Cultural Heritage framework. After one year of incubation, microscopic observations of polished cross-sections were performed to verify if the typical colonization patterns observed in the field may be reproduced in vitro and to evaluate the receptivity of the five lithotypes to endolithic lichens. The mycobionts of the two species developed both on the surface of and within all the lithotypes, showing different penetration pathways which depend on mineralogical and structural features and highlight different receptivity. By contrast, algae inoculated with the coupons did not penetrate them. Observations suggest that the hyphal penetration along intrinsic discontinuities of rocks is a relatively fast phenomenon when these organisms are generally considered as slow-growing. Samples from limestone outcrops and abandoned marble quarries, colonized by the same species or other representatives of Verrucariaceae, showed penetration pathways intriguingly similar to those reproduced in vitro and highlighted that lichen-driven erosion processes only increase the availability of hyphal passageways after a long-term colonization. These results show that in vitro incubation of sterile cultured lichen-forming ascomycetes with rock coupons is a practicable experimental system to investigate the lichen-rock interactions under controlled conditions and, together with analysis in situ, may support decisions on conservative treatments of historical and cultural significant stone substrata.

Risk factors for children's receptive vocabulary development from four to eight years in the longitudinal study of Australian children.

Full Text Available Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC. Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB, low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children

Full Text Available Background: Lecturing is widely used teaching method in higher education. Instructors of large classes may have only option to deliver lecture to convey informations to large group students.Aims and Objectives: The present study was to evaluate the effectiveness/receptivity of interactive lecturing in a large group of MBBS second year students. Material and Methods: The present study was conducted in the well-equipped lecture theater of Dhanalakshmi Srinivasan Medical College and Hospital (DSMCH, Tamil Nadu. A fully prepared interactive lecture on the specific topic was delivered by using power point presentation for second year MBBS students. Before start to deliver the lecture, instructor distributed multiple choice 10 questionnaires to attempt within 10 minutes. After 30 minutes of delivering lecture, again instructor distributed same 10 sets of multiple choice questionnaires to attempt in 10 minutes. The topic was never disclosed to the students before to deliver the lecture. Statistics: We analyzed the pre-lecture & post-lecture questions of each student by applying the paired t-test formula by using www.openepi.com version 3.01 online/offline software and by using Microsoft Excel Sheet Windows 2010. Results: The 31 male, 80 female including 111 students of average age 18.58 years baseline (pre-lecture receptivity mean % was 30.99 ± 14.64 and post-lecture receptivity mean % was increased upto 53.51± 19.52. The only 12 students out of 111 post-lecture receptivity values was less (mean % 25.8± 10.84 than the baseline (mean % 45± 9.05 receptive value and this reduction of receptivity was more towards negative side. Conclusion: In interactive lecture session with power point presentation students/learners can learn, even in large-class environments, but it should be active-learner centered.

Cultural participation has been used both in governmental health policies and as medical therapy, based on the assumption that cultural activities will improve health. Previous population studies and a human intervention study have shown that religious, social and cultural activities predict increased survival rate. The aim of this study was to analyse the association between cultural activity and perceived health, anxiety, depression and satisfaction with life in both genders. The study is based on the third population-based Nord-Trøndelag Health Study (2006-2008), including 50,797 adult participants from Nord-Trøndelag County, Norway. Data on cultural activities, both receptive and creative, perceived health, anxiety, depression and satisfaction with life were collected by comprehensive questionnaires. The logistic regression models, adjusted for relevant cofactors, show that participation in receptive and creative cultural activities was significantly associated with good health, good satisfaction with life, low anxiety and depression scores in both genders. Especially in men, attending receptive, rather than creative, cultural activities was more strongly associated with all health-related outcomes. Statistically significant associations between several single receptive, creative cultural activities and the health-related outcome variables were revealed. This population-based study suggests gender-dependent associations between cultural participation and perceived health, anxiety, depression and satisfaction with life. The results support hypotheses on the effect of cultural activities in health promotion and healthcare, but further longitudinal and experimental studies are warranted to establish a reliable cause-effect relationship.

Dichogamy is a common characteristic among angiosperms, including Piper species. In this genus, the tiny flowers are morphologically similar and have an asynchronous stamen development. However, there is no information on the duration of stigma receptivity and whether it overlaps with pollen release. To better understand mechanisms of floral function in Piper vicosanum, we provide a detailed characterization of the timing of pollen release from the four stamens and the period of stigma receptivity and exposure mode of the receptive areas. We investigated plants of a natural population in a semideciduous seasonal forest (Viçosa, Minas Gerais State, southeastern Brazil), based on chemical tests, light microscopy, and scanning electron microscopy analyses. Incomplete protogyny-a mechanism that favors outcrossing-was recorded. The period of stigma receptivity was long (14 d), and the sequential exposure and senescence of stigmatic papillae occurred gradually and in a basipetal direction. Pollen release began 2-6 d after the beginning of the pistillate phase, with an average pollen viability of 87.7%, during the bisexual flower phase. Pollen was released for up to 6 d and occurred in one stamen at a time. The fruit set observed in tests of self-pollination indicated self-compatibility. The gradual and sequential exposure of stigmatic papillae in P. vicosanum flowers is described here as the mechanism for the long duration of receptivity. Anther development and pollen release were also sequential. These findings are yet unreported reproductive characteristics of the genus and offer new perspectives for future studies on the floral biology of other Piper species. © 2015 Botanical Society of America, Inc.

This study examined the performance of a developed taper-tube concentrator for 94-GHz millimeter-wave beam reception during wireless power transfer. The received energy is converted into kinetic energy of a working gas in the tube to drive an engine or thruster. The concentrator, which is assumed to have mirror reflection of millimeter waves in it, is designed to be shorter than conventional tapered waveguides of millimeter waves. A dimensionless design law of a concentrator is proposed based on geometric optics theory. Because the applicability of geometric optics theory is unclear, the ratio of its bore diameter to its wavelength was set as small compared to those in other possible applications. Then, the discrepancy between the designed and measured power reception was examined. Results show that the maximum discrepancy was as low as 7 % for the bore-to-wavelength ratio of 20 at the narrow end of the concentrator.

The aim of the current study was to examine the relationship between sibship size and children's vocabulary as a function of quality of sibling interactions. It was hypothesized that coming from a larger sibship (ie, 3+ children) would be related to lower receptive vocabulary in children. However, we expected this association to be moderated by the level of cognitive sensitivity shown by children's next-in-age older siblings. Data on 385 children (mean age = 3.15 years) and their next-in-age older siblings (mean age = 5.57 years) were collected and included demographic questionnaires, direct testing of children's receptive vocabulary, and videos of mother-child and sibling interactions. Sibling dyads were taped engaging in a cooperative building task and tapes were coded for the amount of cognitive sensitivity the older sibling exhibited toward the younger sibling. Hierarchical regression analyses were conducted and showed an interaction between sibship size and sibling cognitive sensitivity in the prediction of children's receptive vocabulary; children exposed to large sibships whose next-in-age older sibling exhibited higher levels of cognitive sensitivity were less likely to show low vocabulary skills when compared with those children exposed to large sibships whose siblings showed lower levels of cognitive sensitivity. Children who show sensitivity to the cognitive needs of their younger siblings provide a rich environment for language development. The negative impact of large sibships on language development is moderated by the presence of an older sibling who shows high cognitive sensitivity.

This study extends research on receptivity to tobacco marketing over a key developmental period for cigarette smoking experimentation. The purpose of this study was to understand the effect of receptivity to tobacco marketing and exposure to friends who smoke on smoking experimentation. Participants were 10 to 13 years old who had never tried cigarettes (n = 878), interviewed six times at 8-month intervals. At baseline, 25% percent of the 10 and 11 years old in the sample of never smokers were receptive to tobacco marketing, while less than 5% had friends who smoked. Having a friend who smoked at study baseline and acquiring such friends for the first time during the study were the strongest predictors of smoking experimentation. Initial receptivity to tobacco marketing increased the risk of smoking experimentation independently of having friends who smoke at baseline or acquiring friends who smoke throughout the study period. The high level of receptivity observed even among 10 and 11 years old and its robust relationship with cigarette smoking experimentation independent of the significant risk associated with having friends who smoke suggests that successful prevention of receptivity may require intervention at an early age.

Receptive vocabulary is an important measure for language evaluations. Therefore, norm-referenced receptive vocabulary tests are widely used in several languages. However, a receptive vocabulary test has not yet been normed for Modern Greek. To adapt an American English vocabulary test, the Receptive One-Word Picture Vocabulary Test-II (ROWPVT-II), for Modern Greek for use with Greek-speaking preschool children. The list of 170 English words on ROWPVT-II was adapted by (1) developing two lists (A and B) of Greek words that would match either the target English word or another concept corresponding to one of the pictured objects in the four-picture array; and (2) determining a developmental order for the chosen Greek words for preschool-aged children. For the first task, adult word frequency measures were used to select the words for the Greek wordlist. For the second task, 427 children, 225 boys and 202 girls, ranging in age from 2;0 years to 5;11 years, were recruited from urban and suburban areas of Greece. A pilot study of the two word lists was performed with the aim of comparing an equal number of list A and list B responses for each age group and deriving a new developmental list order. The relative difficulty of each Greek word item, that is, its accuracy score, was calculated by taking the average proportion of correct responses across ages for that word. Subsequently, the word accuracy scores in the two lists were compared via regression analysis, which yielded a highly significant relationship (R(2) = 0.97; p word item from the two lists was a better fit. Finally, new starting levels (basals) were established for preschool ages. The revised word list can serve as the basis for adapting a receptive vocabulary test for Greek preschool-aged children. Further steps need to be taken when testing larger numbers of 2;0 to 5;11-year-old children on the revised word list for determination of norms. This effort will facilitate early identification and remediation

A Multiple-Reception Access Protocol with Interruptions with Mixed Priorities in CDMA Networks

Institute of Scientific and Technical Information of China (English)

2003-01-01

A novel access protocol called Multiple-Reception Access Protocol (MRAP) and its modification MRAP/WI are proposed. In this protocol, all colliding users with a common code can be identified by the base station due to the offset of arrival time Thus they can retransmit access requests under the base station's control. Furthermore new arrivals with higher priority level can interrupt the lower retransmission in order to reduce its access delay although it increases the lower priority's delay. Simulation results of MRAP and MRAP/WI are given in order to highlight the superior performance of the proposed approach.

To Investigate the Absorption, Dynamic Contact Angle and Printability Effects of Synthetic Zeolite Pigments in an Inkjet Receptive Coating

Jalindre, Swaraj Sunil

Ink absorption performance in inkjet receptive coatings containing synthetic zeolite pigments was studied. Coating pigment pore and particle size distribution are the key parameters that influence in modifying media surface properties, thus affecting the rate of ink penetration and drying time (Scholkopf, et al. 2004). The primary objective of this study was: (1) to investigate the synthetic zeolite pigment effects on inkjet ink absorption, dynamic contact angle and printability, and (2) to evaluate these novel synthetic zeolite pigments in replacing the fumed silica pigments in conventional inkjet receptive coatings. In this research study, single pigment coating formulations (in equal P:B ratio) were prepared using microporous synthetic zeolite pigments (5A, Organophilic and 13X) and polyvinyl alcohol (PVOH) binder. The laboratory-coated samples were characterized for absorption, air permeance, roughness, drying time, wettability and print fidelity. Based on the rheological data, it was found that the synthetic zeolite formulated coatings depicted a Newtonian flow behavior at low shear; while the industry accepted fumed silica based coatings displayed a characteristically high pseudoplastic flow behavior. Our coated samples generated using microporous synthetic zeolite pigments produced low absorption, reduced wettability and accelerated ink drying characteristics. These characteristics were caused due to the synthetic zeolite pigments, which resulted in relatively closed surface structure coated samples. The research suggested that no single selected synthetic zeolite coating performed better than the conventional fumed silica based coatings. Experimental data also showed that there was no apparent relationship between synthetic zeolite pigment pore sizes and inkjet ink absorption. For future research, above coated samples should be evaluated for pore size distribution using Mercury Porosimeter, which quantifies surface porosity of coated samples. This presented

To determine whether novelty seeking and depressive symptoms had mediated or indirect effects on adolescent smoking progression through tobacco advertising receptivity. More than 1000 adolescents were monitored from 9th grade to 12th grade and completed annual surveys that measured demographic characteristics, smoking behavior, tobacco advertising receptivity, novelty-seeking personality, depressive symptoms, family and peer smoking, alcohol use, and marijuana use. Latent growth modeling indicated that novelty seeking had a significant indirect effect on smoking progression through baseline tobacco advertising receptivity. For each 1-SD increase in novelty seeking, the odds of being more receptive to tobacco advertising increased by 12% (ie, being in a specific category or higher), which in turn resulted in an 11% increase in the odds of smoking progression from 9th grade to 12th grade. The indirect effect from depressive symptoms to smoking progression did not reach significance. These findings may inform future research on other factors that influence tobacco advertising receptivity, as well as programs aimed at preventing adolescent smoking initiation and progression.

From Iser to Turner and beyond: reception theory meets cognitive criticism

Directory of Open Access Journals (Sweden)

Craig Hamilton

2012-01-01

Full Text Available In this essay, we review the work of Wolfgang Iser, the major proponent of reception theory, and Mark Turner, the major proponent of cognitive criticism. The two theoretical lines advocated by Iser and Turner focus on the cognitive processes involved with reading literary texts. Unfortunately, bibliographic blind spots in both lines lead to the assumption that there is little overlap between reception theory and cognitive criticism. We put this assumption to rest by comparing and contrasting works by Iser and Turner in detail, starting with Iser’s work in the mid-1970s and ending with Turner’s work in the late 1990s.

Users’ Encounter With Normative Discourses on Facebook: A Three-Pronged Analysis of User Agency as Power Structure, Nexus, and Reception

Directory of Open Access Journals (Sweden)

David Mathieu

2016-12-01

Full Text Available This study asks whether users’ encounter with normative discourses of lifestyle, consumption, and health on social media such as Facebook gives rise to agency. The theoretical framework draws on reception analysis, for its implied, but central interest in agency that lies at the intersection of texts and audiences. Based on a critique of the “participatory paradigm,” a paradigm that situates the locus of agency in the structural opposition between senders and users, in the norms of rational deliberation or in the figure of the activist, gaps are identified which can be filled by adopting an explicit focus on the socio-cultural practices of ordinary audiences in their encounters with media discourses. The study investigates user agency on seven Facebook groups and pages with the help of a three-pronged perspective based on the notion of the media–audience relationship as (1 power structure, (2 nexus, and (3 reception. The analysis reveals that the structure at play on these Facebook groups and pages does not encourage user agency. However, user agency manifests itself through user interactions and expressive sense-making processes associated with reception. The benefits of such audience agency are a public, collective, and communicative sense-making process and an expansion of the professionally controlled text.

Experiencing different quality images in the two eyes soon after birth can cause amblyopia, a developmental vision disorder. Amblyopic humans show the reduced capacity for judging the relative position of a visual target in reference to nearby stimulus elements (position uncertainty) and often experience visual image distortion. Although abnormal pooling of local stimulus information by neurons beyond striate cortex (V1) is often suggested as a neural basis of these deficits, extrastriate neurons in the amblyopic brain have rarely been studied using microelectrode recording methods. The receptive field (RF) of neurons in visual area V2 in normal monkeys is made up of multiple subfields that are thought to reflect V1 inputs and are capable of encoding the spatial relationship between local stimulus features. We created primate models of anisometropic amblyopia and analyzed the RF subfield maps for multiple nearby V2 neurons of anesthetized monkeys by using dynamic two-dimensional noise stimuli and reverse correlation methods. Unlike in normal monkeys, the subfield maps of V2 neurons in amblyopic monkeys were severely disorganized: subfield maps showed higher heterogeneity within each neuron as well as across nearby neurons. Amblyopic V2 neurons exhibited robust binocular suppression and the strength of the suppression was positively correlated with the degree of hereogeneity and the severity of amblyopia in individual monkeys. Our results suggest that the disorganized subfield maps and robust binocular suppression of amblyopic V2 neurons are likely to adversely affect the higher stages of cortical processing resulting in position uncertainty and image distortion.

In amblyopia, a visual disorder caused by abnormal visual experience during development, the amblyopic eye (AE) loses visual sensitivity whereas the fellow eye (FE) is largely unaffected. Binocular vision in amblyopes is often disrupted by interocular suppression. We used 96-electrode arrays to record neurons and neuronal groups in areas V1 and V2 of six female macaque monkeys ( Macaca nemestrina ) made amblyopic by artificial strabismus or anisometropia in early life, as well as two visually normal female controls. To measure suppressive binocular interactions directly, we recorded neuronal responses to dichoptic stimulation. We stimulated both eyes simultaneously with large sinusoidal gratings, controlling their contrast independently with raised-cosine modulators of different orientations and spatial frequencies. We modeled each eye's receptive field at each cortical site using a difference of Gaussian envelopes and derived estimates of the strength of central excitation and surround suppression. We used these estimates to calculate ocular dominance separately for excitation and suppression. Excitatory drive from the FE dominated amblyopic visual cortex, especially in more severe amblyopes, but suppression from both the FE and AEs was prevalent in all animals. This imbalance created strong interocular suppression in deep amblyopes: increasing contrast in the AE decreased responses at binocular cortical sites. These response patterns reveal mechanisms that likely contribute to the interocular suppression that disrupts vision in amblyopes. SIGNIFICANCE STATEMENT Amblyopia is a developmental visual disorder that alters both monocular vision and binocular interaction. Using microelectrode arrays, we examined binocular interaction in primary visual cortex and V2 of six amblyopic macaque monkeys ( Macaca nemestrina ) and two visually normal controls. By stimulating the eyes dichoptically, we showed that, in amblyopic cortex, the binocular combination of signals is

Full Text Available There is a long tradition of investigating various disorders of musical abilities after stroke. These impairments, associated with acquired amusia, can be highly selective, affecting only music perception (i.e., receptive abilities/functions or expression (music production abilities, and some patients report that these may dramatically influence their emotional state. The aim of this study was to systematically test both the melodic and rhythmic domains of music perception and expression in left- and right-sided stroke patients compared to healthy subjects. Music perception was assessed using rhythmic and melodic discrimination tasks, while tests of expressive function involved the vocal or instrumental reproduction of rhythms and melodies. Our approach revealed deficits in receptive and expressive functions in stroke patients, mediated by musical expertise. Those patients who had experienced a short period of musical training in childhood and adolescence performed better in the receptive and expressive subtests compared to those without any previous musical training. While discrimination of specific musical patterns was unimpaired after a right-sided stroke, patients with a left-sided stroke had worse results for fine melodic and rhythmic analysis. In terms of expressive testing, the most consistent results were obtained from a test that required patients to reproduce sung melodies. This implies that the means of investigating production abilities can impact the identification of deficits.

These impairments, associated with acquired amusia, can be highly selective, affecting only music perception (i.e., receptive abilities/functions) or expression (music production abilities), and some patients report that these may dramatically influence their emotional state. The aim of this study was to systematically test both the melodic and rhythmic domains of music perception and expression in left- and right-sided stroke patients compared to healthy subjects. Music perception was assessed using rhythmic and melodic discrimination tasks, while tests of expressive function involved the vocal or instrumental reproduction of rhythms and melodies. Our approach revealed deficits in receptive and expressive functions in stroke patients, mediated by musical expertise. Those patients who had experienced a short period of musical training in childhood and adolescence performed better in the receptive and expressive subtests compared to those without any previous musical training. While discrimination of specific musical patterns was unimpaired after a left-sided stroke, patients with a right-sided stroke had worse results for fine melodic and rhythmic analysis. In terms of expressive testing, the most consistent results were obtained from a test that required patients to reproduce sung melodies. This implies that the means of investigating production abilities can impact the identification of deficits.

Adolescents from different ethnic groups show different cigarette smoking prevalence rates, suggesting potential differences in receptivity to and influences from protobacco media. Understanding these differences will be helpful in tailoring smoking prevention and cessation programs for diverse adolescent populations in the United States. Data from cross-sectional surveys of 20,332 randomly sampled California boys and girls, 12-17 years of age, were analyzed. Results indicate that receptivity to protobacco media was lower among African Americans, Asian Americans, and Hispanics than among White youth. There was a consistent dose-response relationship between receptivity to protobacco media and 30-day cigarette smoking across ethnic groups. Having a cigarette brand preference was associated with the highest risk for cigarette smoking, having a favorite tobacco ad showed the lowest risk, while having received or being willing to use tobacco promotional items was associated with a moderate risk. After controlling for 13 covariates, the odds ratio for receptivity to protobacco media and 30-day cigarette smoking was significant for Whites (RR = 1.38, p 0.05) and Asian American (RR = 1.17, p > 0.05) youth. African American, Asian American, and Hispanic adolescents have a lower level of receptivity to protobacco media than do Whites. The association between media receptivity and 30-day cigarette smoking exists for all four ethnic groups without controlling for other smoking predictor variables, but only for Hispanics and Whites when other variables are controlled. Protecting adolescents from protobacco advertising influences is an important element in tobacco control among ethnic minority youth.

In this work, the collection of solar energy by a broad-band nanospiral antenna is investigated in order to solve the low efficiency of the solar rectenna based on conventional nanoantennas. The antenna impedance, radiation, polarization and effective area are all considered in the efficiency calculation using the finite integral technique. The wavelength range investigated is 300-3000 nm, which corresponds to more than 98% of the solar radiation energy. It's found that the nanospiral has stronger field enhancement in the gap than a nanodipole counterpart. And a maximum harvesting efficiency about 80% is possible in principle for the nanospiral coupled to a rectifier resistance of 200 Ω, while about 10% for the nanodipole under the same conditions. Moreover, the nanospiral could be coupled to a rectifier diode of high resistance more easily than the nanodipole. These results indicate that the efficient full-spectrum utilization, reception and conversion of solar energy can be achieved by the nanospiral antenna, which is expected to promote the solar rectenna to be a promising technology in the clean, renewable energy application.

Werner Sombart and his reception in Italy

Simona Pisanelli

2015-03-01

Full Text Available This article intends to focus on the difficulty encountered by Werner Sombart’s works in gaining a hearing in various Italian intellectual circuits. As is well known, Sombart belonged to the German Historical School of economics, sharing with other scholars of that school the same problems in getting his work known in Italy. Our aim is to explain the reason for this hostile reception. First of all, we will analyze the factors which generally hindered the spread of the German Historical School in Italy, recognizing in economists like Francesco Ferrara, Idealists like Benedetto Croce and Marxists like Antonio Labriola some of its strongest opponents. We will dwell on the cases of Gustav Schmoller and Max Weber, in order to give two representative examples of the slow and complicated Italian reception of methodological approaches and analytical perspectives which characterized the scientific experience of the German Historical School. Secondly, we will try to show why Sombart was even less appreciated than other German social scientists, giving the reasons that attracted severe criticism from economists, economic historians and sociologists towards his interdisciplinary approach in the analysis of modern capitalism. Finally, we will show the reasons of the contemporary rediscovery of Sombart and of his works.

2014-11-01

The authors examined the effects of conceptual scoring on the performance of simultaneous and sequential bilinguals on standardized receptive and expressive vocabulary measures in English and Spanish. Participants included 40 English-speaking monolingual children, 39 simultaneous Spanish-English bilingual children, and 19 sequential bilingual children, ages 5-7. The children completed standardized receptive and expressive vocabulary measures in English and also in Spanish for those who were bilingual. After the standardized administration, bilingual children were given the opportunity to respond to missed items in their other language to obtain a conceptual score. Controlling for group differences in socioeconomic status (SES), both simultaneous and sequential bilingual children scored significantly below monolingual children on single-language measures of English receptive and expressive vocabulary. Conceptual scoring removed the significant difference between monolingual and simultaneous bilingual children in the receptive modality but not in the expressive modality; differences remained between monolingual and sequential bilingual children in both modalities. However, in both bilingual groups, conceptual scoring increased the proportion of children with vocabulary scores within the average range. Conceptual scoring does not fully ameliorate the bias inherent in single-language standardized vocabulary measures for bilingual children, but the procedures employed here may assist in ruling out vocabulary deficits, particularly in typically developing simultaneous bilingual children.

The current study attempted to investigate the development of Arabic academic vocabulary knowledge among middle-school Arabic native speakers, taking into account the socioeconomic status of the Arab population in Israel. For this purpose, Arabic academic word list was developed, mapping the required academic words that are needed for adequate coping with informational texts as appearing in the different content areas text-books. Six-hundred Arabic speaking middle school pupils from the different areas in Israel, representing the different Arab subgroups: general Arab community, Druze and Bedouins, have participated in the current study. Two academic vocabulary tests, including receptive and productive academic vocabulary evaluation tests, were administrated to the students across the different age groups (7th, 8th and 9th). The results pointed to no significant difference between 7th and 9th grade in academic vocabulary knowledge. In contrast, significant difference was encountered between the different Arab sub-groups where the lowest scores were noted among the Bedouin sub-group, characterized by the lowest SES. When comparing receptive and productive academic vocabulary knowledge between 7th and 9th grade, the results pointed to improvement in receptive academic knowledge towards the end of middle school but not on the productive knowledge level. In addition, within participants' comparison indicated a gap between the pupils' receptive and productive vocabulary. The results are discussed in relation to the existing scientific literature and to its implication of both research and practice in the domain of Arabic literacy development.

Cigarette marketing contributes to initiation of cigarette smoking among young people, which has led to restrictions on use of cigarette advertising. However, little is known about other tobacco advertising and progression to tobacco use in youth and young adults. To investigate whether receptivity to tobacco advertising among youth and young adults is associated with progression (being a susceptible never user or ever user) to use of the product advertised, as well as conventional cigarette smoking. The Population Assessment of Tobacco and Health (PATH) Study at wave 1 (2013-2014) and 1-year follow-up at wave 2 (2014-2015) was conducted in a US population-based sample of never tobacco users aged 12 to 24 years from wave 1 of the PATH Study (N = 10 989). Household interviews using audio computer-assisted self-interviews were conducted. Advertising for conventional cigarettes, electronic cigarettes (e-cigarettes), cigars, and smokeless tobacco products at wave 1. Progression to susceptibility or ever tobacco use at 1-year follow-up in wave 2. Of the 10 989 participants (5410 male [weighted percentage, 48.3%]; 5579 female [weighted percentage, 51.7%]), receptivity to any tobacco advertising at wave 1 was high for those aged 12 to 14 years (44.0%; 95% confidence limit [CL], 42.6%-45.4%) but highest for those aged 18 to 21 years (68.7%; 95% CL, 64.9%-72.2%). e-Cigarette advertising had the highest receptivity among all age groups. For those aged 12 to 17 years, susceptibility to use a product at wave 1 was significantly associated with product use at wave 2 for conventional cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among committed never users aged 12 to 17 years at wave 1, any receptivity was associated with progression toward use of the product at wave 2 (conventional cigarettes: adjusted odds ratio [AOR], 1.43; 95% CL, 1.23-1.65; e-cigarettes: AOR, 1.62; 95% CL, 1.41-1.85; cigars: AOR, 2.01; 95% CL, 1.62-2.49; and smokeless (males only

Hypothesis: Co-transfer of genuine embryos and implantation-promoting compounds via artificial containers improve endometrium receptivity.

As with other organs endometrial functions are altered with the advancing age. Age related decrease in reproductive functions leads to decline in the number of oocytes retrieved and the synthesis of endometrial receptivity molecules. Despite the significant improvement in assisted reproductive technologies we do not have so many options to enhance endometrial receptivity. Due to lack of drugs having endometrium receptivity enhancement properties, oocyte donation seems to be the only solution for women with implantation failure. The euploid oocytes come from young and healthy donors may overcome age associated endometrial receptivity defect. Nevertheless, many reasons restrict us from using oocyte donation in women with implantation failure. We, therefore, hypothesized that by mimicking a young blastocyst's effect on endometrium, the transfer of genuine embryos and implantation-promoting compounds together might be the new treatment option for infertile women with recurrent implantation failure. Artificial beads, MI or GV oocytes, and empty zona can be used as a container for intrauterine replacement of implantation-promoting compounds. Copyright © 2017 Elsevier Ltd. All rights reserved.

Flowers have a species-specific functional life span that determines the time window in which pollination, fertilization and seed set can occur. The stigma tissue plays a key role in flower receptivity by intercepting pollen and initiating pollen tube growth toward the ovary. In this article, we show that a developmentally controlled cell death programme terminates the functional life span of stigma cells in Arabidopsis. We identified the leaf senescence regulator ORESARA1 (also known as ANAC092) and the previously uncharacterized KIRA1 (also known as ANAC074) as partially redundant transcription factors that modulate stigma longevity by controlling the expression of programmed cell death-associated genes. KIRA1 expression is sufficient to induce cell death and terminate floral receptivity, whereas lack of both KIRA1 and ORESARA1 substantially increases stigma life span. Surprisingly, the extension of stigma longevity is accompanied by only a moderate extension of flower receptivity, suggesting that additional processes participate in the control of the flower's receptive life span.

As rates of prematurity continue to rise, identifying which preterm children are at increased risk for learning disabilities is a public health imperative. Identifying continuities between early and later skills in this vulnerable population can also illuminate fundamental neuropsychological processes that support learning in all children. At 18 months adjusted age, we used socioeconomic status (SES), medical variables, parent-reported vocabulary, scores on the Bayley Scales of Infant and Toddler Development (third edition) language composite, and children's lexical processing speed in the looking-while-listening (LWL) task as predictor variables in a sample of 30 preterm children. Receptive vocabulary as measured by the Peabody Picture Vocabulary Test (fourth edition) at 36 months was the outcome. Receptive vocabulary was correlated with SES, but uncorrelated with degree of prematurity or a composite of medical risk. Importantly, lexical processing speed was the strongest predictor of receptive vocabulary (r = -.81), accounting for 30% unique variance. Individual differences in lexical processing efficiency may be able to serve as a marker for information processing skills that are critical for language learning.

Risk factors for low receptive vocabulary abilities in the preschool and early school years in the longitudinal study of Australian children.

Directory of Open Access Journals (Sweden)

Daniel Christensen

Full Text Available Receptive vocabulary development is a component of the human language system that emerges in the first year of life and is characterised by onward expansion throughout life. Beginning in infancy, children's receptive vocabulary knowledge builds the foundation for oral language and reading skills. The foundations for success at school are built early, hence the public health policy focus on reducing developmental inequalities before children start formal school. The underlying assumption is that children's development is stable, and therefore predictable, over time. This study investigated this assumption in relation to children's receptive vocabulary ability. We investigated the extent to which low receptive vocabulary ability at 4 years was associated with low receptive vocabulary ability at 8 years, and the predictive utility of a multivariate model that included child, maternal and family risk factors measured at 4 years. The study sample comprised 3,847 children from the first nationally representative Longitudinal Study of Australian Children (LSAC. Multivariate logistic regression was used to investigate risks for low receptive vocabulary ability from 4-8 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. In the multivariate model, substantial risk factors for receptive vocabulary delay from 4-8 years, in order of descending magnitude, were low receptive vocabulary ability at 4 years, low maternal education, and low school readiness. Moderate risk factors, in order of descending magnitude, were low maternal parenting consistency, socio-economic area disadvantage, low temperamental persistence, and NESB status. The following risk factors were not significant: One or more siblings, low family income, not reading to the child, high maternal work hours, and Aboriginal or Torres Strait Islander ethnicity. The results of the sensitivity-specificity analysis showed that a well

In order to assess the stability of high speed machining, estimate the frequency response at the end of tool tip is of great importance. Evaluating dynamic response of several combinations of integrated spindle-tool holder-tool will consume a lot of time. This paper presents coupled field dynamic response at tool tip for the entire integrated spindle tool unit. The spindle unit is assumed to be relying over the front and rear bearings and investigated using the Timoshenko beam theory to arrive the receptances at different locations of the spindle-tool unit. The responses are further validated with conventional finite element model as well as with the experiments. This approach permits quick outputs without losing accuracy of solution and further these methods are utilized to analyze the various design variables on system dynamics. The results obtained through this analysis are needed to design the better spindle unit in an attempt to reduce the frequency amplitudes at the tool tip to improvise the milling stability during cutting process.

Receptive Language Skills in Slovak-Speaking Children With Intellectual Disability: Understanding Words, Sentences, and Stories.

Polišenská, Kamila; Kapalková, Svetlana; Novotková, Monika

2018-06-05

The study aims to describe receptive language skills in children with intellectual disability (ID) and to contribute to the debate on deviant versus delayed language development. This is the 1st study of receptive skills in children with ID who speak a Slavic language, providing insight into how language development is affected by disability and also language typology. Twenty-eight Slovak-speaking children participated in the study (14 children with ID and 14 typically developing [TD] children matched on nonverbal reasoning abilities). The children were assessed by receptive language tasks targeting words, sentences, and stories, and the groups were compared quantitatively and qualitatively. The groups showed similar language profiles, with a better understanding of words, followed by sentences, with the poorest comprehension for stories. Nouns were comprehended better than verbs; sentence constructions also showed a qualitatively similar picture, although some dissimilarities emerged. Verb comprehension was strongly related to sentence comprehension in both groups and related to story comprehension in the TD group only. The findings appear to support the view that receptive language skills follow the same developmental route in children with ID as seen in younger TD children, suggesting that language development is a robust process and does not seem to be differentially affected by ID even when delayed.

To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes. Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations.

Sensitivity-based virtual fields for the non-linear virtual fields method

Science.gov (United States)

Marek, Aleksander; Davis, Frances M.; Pierron, Fabrice

2017-09-01

The virtual fields method is an approach to inversely identify material parameters using full-field deformation data. In this manuscript, a new set of automatically-defined virtual fields for non-linear constitutive models has been proposed. These new sensitivity-based virtual fields reduce the influence of noise on the parameter identification. The sensitivity-based virtual fields were applied to a numerical example involving small strain plasticity; however, the general formulation derived for these virtual fields is applicable to any non-linear constitutive model. To quantify the improvement offered by these new virtual fields, they were compared with stiffness-based and manually defined virtual fields. The proposed sensitivity-based virtual fields were consistently able to identify plastic model parameters and outperform the stiffness-based and manually defined virtual fields when the data was corrupted by noise.

The 1623 Plan for Global Governance: the obscure history of its reception

Full Text Available Abstract In the present article we analyze the characteristics and the reception of the first plan for global governance, the New Cyneas by Émeric Crucé. With this goal in mind, we examine the history of its readings and the possible influence on the Duke of Sully's project for European confederation, the case most often cited by historians of ideas. Our analysis takes into consideration the 17th century reception, the scant dissemination of the work and the possible causes of its limited impact. Our conclusions support, on the one hand, the novelty of Crucé's principal ideas, and on the other, their limited impact over the time with the exception of the period surrounding the creation of the League of Nations.

Fusing Panchromatic and SWIR Bands Based on Cnn - a Preliminary Study Over WORLDVIEW-3 Datasets

Science.gov (United States)

Guo, M.; Ma, H.; Bao, Y.; Wang, L.

2018-04-01

The traditional fusion methods are based on the fact that the spectral ranges of the Panchromatic (PAN) and multispectral bands (MS) are almost overlapping. In this paper, we propose a new pan-sharpening method for the fusion of PAN and SWIR (short-wave infrared) bands, whose spectral coverages are not overlapping. This problem is addressed with a convolutional neural network (CNN), which is trained by WorldView-3 dataset. CNN can learn the complex relationship among bands, and thus alleviate spectral distortion. Consequently, in our network, we use the simple three-layer basic architecture with 16 × 16 kernels to conduct the experiment. Every layer use different receptive field. The first two layers compute 512 feature maps by using the 16 × 16 and 1 × 1 receptive field respectively and the third layer with a 8 × 8 receptive field. The fusion results are optimized by continuous training. As for assessment, four evaluation indexes including Entropy, CC, SAM and UIQI are selected built on subjective visual effect and quantitative evaluation. The preliminary experimental results demonstrate that the fusion algorithms can effectively enhance the spatial information. Unfortunately, the fusion image has spectral distortion, it cannot maintain the spectral information of the SWIR image.

The public reception of the Research Assessment Exercise 1996.

Full Text Available This paper reviews the public reception of the Research Assessment Exercise 1996 (RAE from its announcement in December 1996 to the decline of discussion at end May 1997. A model for diffusion of the RAE is established which distinguishes extra-communal (or exoteric from intra-communal (or esoteric media. The different characteristics of each medium and the changing nature of the discussion over time are considered. Different themes are distinguished in the public reception of the RAE: the spatial distribution of research; the organisation of universities; disciplinary differences in understanding; a perceived conflict between research and teaching; the development of a culture of accountability; and analogies with the organisation of professional football. In conclusion, it is suggested that the RAE and its effects can be more fully considered from the perspective of scholarly communication and understandings of the development of knowledge than it has been by previous contributions in information science, which have concentrated on the possibility of more efficient implementation of existing processes. A fundamental responsibility for funding councils is also identified: to promote the overall health of university education and research, while establishing meaningful differentiations between units.

Seeing, wanting, owning: the relationship between receptivity to tobacco marketing and smoking susceptibility in young people

Feighery, E.; Borzekowski, D.; Schooler, C.; Flora, J.

1998-01-01

OBJECTIVE—To assess the effect of the tobacco industry's marketing practices on adolescents by examining the relationship between their receptivity to these practices and their susceptibility to start smoking.
DESIGN—Paper-and-pencil surveys measuring association with other smokers, exposure to tobacco industry marketing strategies, experience with smoking, and resolve not to smoke in the future.
SETTING—25 randomly selected classrooms in five middle schools in San Jose, California.
SUBJECTS—571 seventh graders with an average age of 13 years and 8 months; 57% were female. Forty-five per cent of the students were Asian, 38% were Hispanic, 12% were white, and 5% were black.
MAIN OUTCOME MEASURES—Exposure to social influences, receptivity to marketing strategies, susceptibility to start smoking.
RESULTS—About 70% of the participants indicated at least moderate receptivity to tobacco marketing materials. Children who are more receptive are also more susceptible to start smoking. In addition to demographics and social influences, receptivity to tobacco marketing materials was found to be strongly associated with susceptibility.
CONCLUSIONS—Tobacco companies conduct marketing campaigns that effectively capture teenage attention and stimulate desire for their promotional items. These marketing strategies may function to move young teenagers from non-smoking status toward regular use of tobacco. Our results demonstrate that there is a clear association between tobacco marketing practices and youngsters' susceptibility to smoke. The findings, along with other research, provide compelling support for regulating the manner in which tobacco products are marketed, to protect young people from the tobacco industry's strategies to reach them.

Maier, Michelle F; Bohlmann, Natalie L; Palacios, Natalia A

The increasing population of dual language learners (DLLs) entering preschool classrooms highlights a continued need for research on the development of dual language acquisition, and specifically vocabulary skills, in this age group. This study describes young DLL children's ( N = 177) vocabulary development in both English and Spanish simultaneously, and how vocabulary skills in each language relate to one another, during a contextual shift that places greater emphasis on the acquisition of academic English language skills. Findings demonstrated that DLL preschoolers made gains in vocabulary in both languages with more change evidenced in receptive, in comparison to expressive, vocabulary as well as in English in comparison to Spanish. When examining whether children's vocabulary scores in one language at the beginning of preschool interact with their vocabulary scores in the other language to predict vocabulary growth, no significant associations were found for receptive vocabulary. In contrast, the interaction between initial English and Spanish expressive vocabulary scores was negatively related to growth in English expressive vocabulary. This cross-language association suggests that children who have low expressive vocabulary skills in both languages tend to grow faster in their English expressive vocabulary. The study extends previous work on dual language development by examining growth in expressive and receptive vocabulary in both English and Spanish. It also provides suggestions for future work to inform a more comprehensive understanding of DLL children's development in both languages.

To investigate community engagement with the health benefits of dietary fibre (DF) and its potential as a framework for the promotion of increased consumption of resistant starch (RS). A nationwide postal Food and Health Survey conducted in Australia by CSIRO Human Nutrition. Adults aged 18 years and above, selected at random from the Australian Electoral Roll (n 849). A cross-sectional design was employed to analyse ratings of (i) the importance of various RS health and functional claims and (ii) receptiveness to different foods as RS delivery vehicles, according to the respondents' level of fibre engagement as classified under the Precaution Adoption Process Model (PAPM) of Health Behaviour. There was a high level of recognition (89·5 %) of DF as being important for health. Significant gender differences were found for ratings of RS attributes and RS delivery options. Women were both more fibre-engaged than men and more receptive than men to RS and its potential benefits. Ratings of the acceptability of several foods as means of delivering RS revealed a general preference for healthy staples over indulgences, with the margin between acceptability of staples and indulgences increasing markedly with increased fibre engagement. Application of the PAPM to awareness of DF reveals a ready-made target group for health messages about RS and pockets of differential potential receptiveness. The findings support the promotion of RS as providing health benefits of DF with the added reduction of risk of serious disease, its delivery through healthy staples and the targeting of messages at both fibre-engaged individuals and women in general.

To determine neutrons multiplication the measurements and calculations of spatial distributions of neutron counting and absolute fission rates in a reception capacity of IPPE radioactive waste shop have been carried out and analyzed. A content of fissionable medium was unknown. The approach developed has allowed implementing a calculation analysis of the experimental data on determination of the most probable spatial distributions of basic parameters of the fissionable medium of unknown content. It has allowed determining the neutrons multiplication factor in a reception capacity of a tank No. 17. It has been found that the value of neutrons multiplication factor in a tank is 1.07 ± 0.03. The developed measurement method and calculation analysis used for experimental data also can be applied in other cases when the multiplication medium content is unknown [ru

2017-11-01

Full Text Available This article identifies problems of translation of J.R.R. Tolkien`s works to the Russian language. Due to complexity of their reception in the Russian literature and culture, these problems continue at the present time. The purpose of this article is to consider the translational interpretations as a form of reception of J.R.R. Tolkien`s works in Russia and perform analysis of relevant stages of the receptive process. The leading approach to the study of this problem is the methodology of receptive aesthetics; this takes into account the development trends of the method. This research shows that it is the translation, in many respects, that sets trends for further understanding of writings by J.R.R. Tolkien in Russia and includes them in a Russian cultural and literary context, as well as set their level of systematic perception. Contents of this article may be used for readings in general and special courses for Western literature at universities, and may be useful to a wide range of readers interested in the work of J.R.R. Tolkien.

Lexical knowledge of Serbian L1 English L2 learners: Reception vs. production

Directory of Open Access Journals (Sweden)

Danilović-Jeremić Jelena

2015-01-01

Full Text Available The acquisition of lexical knowledge in a second/foreign language is often investigated by means of vocabulary size tests which assess two aspects of the learners' competence: reception and production. Estimates of these two dimensions, as well as the (potential gap between them, have important pedagogical implications in that they indicate the degree to which the learners can comprehend or use the language autonomously. Therefore, the aim of this paper is to explore the vocabulary size of three generations of B2-level L2 learners (CEFR, first-year students majoring in English at the Faculty of Philology and Arts in Kragujevac, Serbia, by means of Vocabulary Levels Tests (Laufer & Nation, 1999; Nation, 1990. The results of the statistical analyses show that the receptive vocabulary of Serbian L2 learners is much more developed than their productive vocabulary, and that the gap between lexical production and reception changes depending on the frequency of the lexemes and the proficiency level of L2 learners. The findings imply that, at the primary and secondary level of education, more attention should be paid to the development of productive lexical knowledge which is crucial not only for success in English degree courses but communication in English in general.

To analyze the influence of health professionals' receptiveness on parental care of children with retinopathy of prematurity (ROP). A qualitative study developed under the theoretical framework of Symbolic Interactionism and using a narrative research methodology. Six women and three men, being parents of children with retinopathy of prematurity were individually interviewed in depth. From the scope of information, emotions and their rights, the parents experienced receptiveness from some professionals and unreceptiveness from others. The predominance of unreceptive attitudes in the parental narratives originated the following analysis themes: Informational (un)receptiveness, Emotional (un)receptiveness, and (Un)receptiveness of rights. The study supports human and comprehensive healthcare in the context of retinopathy of prematurity by pointing out the interactive process with health professionals as a potential stressor of parental care. The results signal a nuclear of attitudinal changes and reinforce challenges to the child and family-centered approach.

Acoustic receptivity and transition modeling of Tollmien-Schlichting disturbances induced by distributed surface roughness

Raposo, Henrique; Mughal, Shahid; Ashworth, Richard

2018-04-01

Acoustic receptivity to Tollmien-Schlichting waves in the presence of surface roughness is investigated for a flat plate boundary layer using the time-harmonic incompressible linearized Navier-Stokes equations. It is shown to be an accurate and efficient means of predicting receptivity amplitudes and, therefore, to be more suitable for parametric investigations than other approaches with direct-numerical-simulation-like accuracy. Comparison with the literature provides strong evidence of the correctness of the approach, including the ability to quantify non-parallel flow effects. These effects are found to be small for the efficiency function over a wide range of frequencies and local Reynolds numbers. In the presence of a two-dimensional wavy-wall, non-parallel flow effects are quite significant, producing both wavenumber detuning and an increase in maximum amplitude. However, a smaller influence is observed when considering an oblique Tollmien-Schlichting wave. This is explained by considering the non-parallel effects on receptivity and on linear growth which may, under certain conditions, cancel each other out. Ultimately, we undertake a Monte Carlo type uncertainty quantification analysis with two-dimensional distributed random roughness. Its power spectral density (PSD) is assumed to follow a power law with an associated uncertainty following a probabilistic Gaussian distribution. The effects of the acoustic frequency over the mean amplitude of the generated two-dimensional Tollmien-Schlichting waves are studied. A strong dependence on the mean PSD shape is observed and discussed according to the basic resonance mechanisms leading to receptivity. The growth of Tollmien-Schlichting waves is predicted with non-linear parabolized stability equations computations to assess the effects of stochasticity in transition location.

DeGaudenzi, Riccardo; Giannetti, Filippo

1995-01-01

The downlink of a satellite-mobile personal communication system employing power-controlled Direct Sequence Code Division Multiple Access (DS-CDMA) and exploiting satellite-diversity is analyzed and its performance compared with a more traditional communication system utilizing single satellite reception. The analytical model developed has been thoroughly validated by means of extensive Monte Carlo computer simulations. It is shown how the capacity gain provided by diversity reception shrinks considerably in the presence of increasing traffic or in the case of light shadowing conditions. Moreover, the quantitative results tend to indicate that to combat system capacity reduction due to intra-system interference, no more than two satellites shall be active over the same region. To achieve higher system capacity, differently from terrestrial cellular systems, Multi-User Detection (MUD) techniques are likely to be required in the mobile user terminal, thus considerably increasing its complexity.

An effective bidirectional communication between an implantation-competent blastocyst and the receptive uterus is a prerequisite for mammalian reproduction. The blastocyst will implant only when this molecular cross-talk is established. Here we show that the muscle segment homeobox gene (Msh) family members Msx1 and Msx2, which are two highly conserved genes critical for epithelial-mesenchymal interactions during development, also play crucial roles in embryo implantation. Loss of Msx1/Msx2 expression correlates with altered uterine luminal epithelial cell polarity and affects E-cadherin/β-catenin complex formation through the control of Wnt5a expression. Application of Wnt5a in vitro compromised blastocyst invasion and trophoblast outgrowth on cultured uterine epithelial cells. The finding that Msx1/Msx2 genes are critical for conferring uterine receptivity and readiness to implantation could have clinical significance, because compromised uterine receptivity is a major cause of pregnancy failure in IVF programs.

In Maryland, there have been no military/civilian training exercises of the Medical Mutual Aid Agreement for >20 years. The aims of this paper are to describe the National Disaster Medical System (NDMS), to coordinate military and civilian medical mutual aid in response to arrival of overseas mass casualties, and to evaluate the mass-casualty reception and bed "surge" capacity of Maryland NDMS Hospitals. Three tabletop exercises and a functional exercise were performed using a simulated, overseas, military mass-casualty event. The first tabletop exercise was with military and civilian NMDS partners. The second tested the revised NDMS activation plan. The third exercised the Authorities of State Emergency Medical System and Walter Reed Army Medical Center Directors of Emergency Medicine over Maryland NDMS hospitals, and their Medical Mutual Aid Agreement. The functional exercise used Homeland Security Exercise Evaluation Program tools to evaluate reception, triage, staging, and transportation of 160 notional patients (including 20 live, moulaged "patients") and one canine. The first tabletop exercise identified deficiencies in operational protocols for military/civilian mass-casualty reception, triage, treatment, and problems with sharing a Unified Command. The second found improvements in the revised NDMS activation plan. The third informed expectations for NDMS hospitals. In the functional exercise, all notional patients were received, triaged, dispatched, and accounted in military and five civilian hospitals within two hours. The canine revealed deficiencies in companion/military animal reception, holding, treatment, and evacuation. Three working groups were suggested: (1) to ensure 100% compliance with triage tags, patient accountability, and return of equipment used in mass casualty events and exercises; (2) to investigate making information technology and imaging networks available for Emergency Operation Centers and Incident Command; and (3) to establish NDMS

The paper is devoted to quantitative experimental investigation of effective mechanisms of excitation of 3D TS instability waves due to distributed boundary layer receptivity to free-stream vortices. Experiments carried out in a self-similar boundary layer with Hartree parameter βH = -0.115 and concentrated on studying two receptivity mechanisms connected with distributed scattering of 3D unsteady free-stream vortices both on the natural boundary layer nonuniformity (smooth surface) and on 2D surface nonuniformity (waviness). Obtained quantitative characteristics (distributed receptivity coefficients) are compared directly with those obtained in Blasius boundary layer. It is found that the adverse pressure gradient leads to reduction of efficiency of the vortex-roughness receptivity mechanism.

Preclinical studies of gestational cocaine exposure (GCE) show evidence of changes in brain function at the anatomical, physiological, and behavioral levels, to include effects on developing dopaminergic systems. In contrast, human studies have produced less consistent results, with most showing small effects or no effects on developmental outcomes. Important changes in brain structure and function occur through adolescence, therefore it is possible that prenatal cocaine exposure has latent effects on neurocognitive (NC) outcome that do not manifest until adolescence or young adulthood. We examined NC function using a set of 5 tasks designed to tap 4 different systems: inhibitory control, working memory, receptive language, and incidental memory. For each NC task, data were collected longitudinally at ages 12, 14.5 and 17 years and examined using generalized estimating equations. One hundred and nine children completed at least two of the three evaluations. Covariates included in the final model were assessment number, gender, participant age at first assessment, caregiver depression, and two composites from the Home Observation for Measurement of the Environment (HOME), Environmental Stimulation and Parental Nurturance. We found no cocaine effects on inhibitory control, working memory, or receptive language (p=0.18). GCE effects were observed on incidental face memory task (p=0.055), and GCE by assessment number interaction effects were seen on the incidental word memory task (p=0.031). Participant performance on inhibitory control, working memory, and receptive language tasks improved over time. HOME Environmental Stimulation composite was associated with better receptive language functioning. With a larger sample size smaller differences between groups may have been detected. This report shows no evidence of latent effects of GCE on inhibitory control, working memory, or receptive language. GCE effects were observed on the incidental face memory task, and GCE by

Pre-Feedback Risk Expectancies and Reception of Low-Risk Health Feedback: Absolute and Comparative Lack of Reassurance.

Science.gov (United States)

Gamp, Martina; Renner, Britta

2016-11-01

Personalised health-risk assessment is one of the most common components of health promotion programs. Previous research on responses to health risk feedback has commonly focused on the reception of bad news (high-risk feedback). The reception of low-risk feedback has been comparably neglected since it is assumed that good news is reassuring and readily received. However, field studies suggest mixed responses to low-risk health feedback. Accordingly, we examine whether pre-feedback risk expectancies can mitigate the reassuring effects of good news. In two studies (N = 187, N = 565), after assessing pre-feedback risk expectancies, participants received low-risk personalised feedback about their own risk of developing (the fictitious) Tucson Chronic Fatigue Syndrome (TCFS). Study 2 also included peer TCFS risk status feedback. Afterwards, self- and peer-related risk perception for TCFS was assessed. In both studies, participants who expected to be at high risk but received good news (unexpected low-risk feedback) showed absolute lack of reassurance. Specifically, they felt at significantly greater TCFS risk than participants who received expected good news. Moreover, the unexpected low-risk group even believed that their risk was as high as (Study 1) or higher (Study 2) than that of their peers (comparative lack of reassurance). Results support the notion that high pre-feedback risk expectancies can mitigate absolute and comparative reassuring effects of good news. © 2016 The International Association of Applied Psychology.

Implantation in assisted reproduction: a look at endometrial receptivity.

Science.gov (United States)

Fatemi, H M; Popovic-Todorovic, B

2013-11-01

Implantation failure in assisted reproduction is thought to be mainly due to impaired uterine receptivity. With normal uterine anatomy, changes in endocrine profile during ovarian stimulation and medical conditions of the mother (i.e. thrombophilia and abnormal immunological response) could result in a non-receptive endometrium. High oestradiol concentrations during ovarian stimulation lead to premature progesterone elevation, causing endometrial advancement and hampering implantation, which can be overcome by a freeze-all approach and embryo transfer in natural cycles or by milder stimulation protocols. Patients with recurrent implantation failure (RIF) should be tested for inherited and acquired thrombophilias. Each patient should be individually assessed and counselled regarding therapy with low-molecular-weight heparin (LMWH). Empirical treatment with LMWH, aspirin or corticosteroids is not effective for women with RIF who have negative thrombophilic tests. If thrombophilic tests are normal, patients should be tested for immunological causes. If human leukocyte antigen dissimilarity is proven, treatment with intravenous immunoglobulin might be beneficial. Preliminary observational studies using intralipid infusion in the presence of increased natural killer cytotoxic activity are interesting but the proposed rationale is controversial and randomized controlled trials are needed. Hysteroscopy and/or endometrial scratching in the cycle preceding ovarian stimulation should become standard for patients with RIF. Copyright © 2013 Reproductive Healthcare Ltd.

The concurrent use of three implicit measures (eye movements, pupillometry, and event-related potentials) to assess receptive vocabulary knowledge in normal adults.

2016-03-01

Recent years have seen the advent and proliferation of the use of implicit techniques to study learning and cognition. One such application is the use of event-related potentials (ERPs) to assess receptive vocabulary knowledge. Other implicit assessment techniques that may be well-suited to other testing situations or to use with varied participant groups have not been used as widely to study receptive vocabulary knowledge. We sought to develop additional implicit techniques to study receptive vocabulary knowledge that could augment the knowledge gained from the use of the ERP technique. Specifically, we used a simple forced-choice paradigm to assess receptive vocabulary knowledge in normal adult participants using eye movement monitoring (EM) and pupillometry. In the same group of participants, we also used an N400 semantic incongruity ERP paradigm to assess their knowledge of two groups of words: those expected to be known to the participants (high-frequency, familiar words) and those expected to be unknown (low-frequency, unfamiliar words). All three measures showed reliable differences between the known and unknown words. EM and pupillometry thus may provide insight into receptive vocabulary knowledge similar to that from ERPs. The development of additional implicit assessment techniques may increase the feasibility of receptive vocabulary testing across a wider range of participant groups and testing situations, and may make the conduct of such testing more accessible to a wider range of researchers, clinicians, and educators.

The Continued Relevance of Reception Analysis in the Age of Social Media

DEFF Research Database (Denmark)

Mathieu, David

2015-01-01

Far from being a remnant of the past, reception analysis must continue to set the question of meaning as a central issue in media studies, an issue that appears to be missing from current understandings of social media in which audiences are often reduced to a single reality or simply ignored...... as empirical reality. This paper argues for the continued relevance of reception analysis, inspite of the mismatch of the label, and develops this argument by applying one of its most fundamental insights, namely its investigation of the relationship between media and audience —or between text and context......—, to the study of social media audiences. In particular, the paper suggests three ways to look at the text-context relationship on Facebook with reference to its use during the “student crisis” in Quebec, Canada in 2012. It suggests three nexuses that represent as many sites of circulation of meaning in society...

Method of optical coherence tomography with parallel depth-resolved signal reception and fibre-optic phase modulators

Energy Technology Data Exchange (ETDEWEB)

Morozov, A N; Turchin, I V [Institute of Applied Physics, Russian Academy of Sciences, Nizhnii Novgorod (Russian Federation)

2013-12-31

The method of optical coherence tomography with the scheme of parallel reception of the interference signal (P-OCT) is developed on the basis of spatial paralleling of the reference wave by means of a phase diffraction grating producing the appropriate time delay in the Mach–Zehnder interferometer. The absence of mechanical variation of the optical path difference in the interferometer essentially reduces the time required for 2D imaging of the object internal structure, as compared to the classical OCT that uses the time-domain method of the image construction, the sensitivity and the dynamic range being comparable in both approaches. For the resulting field of the interfering object and reference waves an analytical expression is derived that allows the calculation of the autocorrelation function in the plane of photodetectors. For the first time a method of linear phase modulation by 2π is proposed for P-OCT systems, which allows the use of compact high-frequency (a few hundred kHz) piezoelectric cell-based modulators. For the demonstration of the P-OCT method an experimental setup was created, using which the images of the inner structure of biological objects at the depth up to 1 mm with the axial spatial resolution of 12 μm were obtained.

2015-01-01

Based on the acoustic radiation theory of a dipole source, the influence of the transducer reception pattern is studied for magnetoacoustic tomography with magnetic induction (MAT-MI). Numerical studies are conducted to simulate acoustic pressures, waveforms, and reconstructed images with unidirectional, omnidirectional, and strong directional transducers. With the analyses of equivalent and projection sources, the influences of the model dimension and the layer effect are qualitatively analyzed to evaluate the performance of MAT-MI. Three-dimensional simulation studies show that the strong directional transducer with a large radius can reduce the influences of equivalent sources, projection sources, and the layer effect effectively, resulting in enhanced pressure and improved image contrast, which is beneficial for boundary pressure extraction in conductivity reconstruction. The reconstructed conductivity contrast images present the conductivity boundaries as stripes with different contrasts and polarities, representing the values and directions of the conductivity changes of the scanned layer. The favorable results provide solid evidence for transducer selection and suggest potential practical applications of MAT-MI in biomedical imaging. (paper)

The reception of Austrian economics in Italy

2018-04-01

Full Text Available Nowadays the Austrian School enjoys high reputation in Italy: books by Mises, Hayek and other Austrian economists are constantly republished and reviewed with great interest, both inside and outside academic circles. The situation was very different decades ago, when just a few Italian economists devoted attention to the Austrian School. This work studies the reception of Austrian Economics in Italy, from the beginning to our days, so as to bring out, by way of comparison, relevant features of Italian economic culture. We will try to offer just an overview of the entire story, in an attempt to provide useful elements for a deeper analysis of further topics and periods.

Evaluation of thin discontinuities in planar conducting materials using the diffraction of electromagnetic field

Science.gov (United States)

Savin, A.; Novy, F.; Fintova, S.; Steigmann, R.

2017-08-01

The current stage of nondestructive evaluation techniques imposes the development of new electromagnetic (EM) methods that are based on high spatial resolution and increased sensitivity. In order to achieve high performance, the work frequencies must be either radifrequencies or microwaves. At these frequencies, at the dielectric/conductor interface, plasmon polaritons can appear, propagating between conductive regions as evanescent waves. In order to use the evanescent wave that can appear even if the slits width is much smaller that the wavwelength of incident EM wave, a sensor with metamaterial (MM) is used. The study of the EM field diffraction against the edge of long thin discontinuity placed under the inspected surface of a conductive plate has been performed using the geometrical optics principles. This type of sensor having the reception coils shielded by a conductive screen with a circular aperture placed in the front of reception coil of emission reception sensor has been developed and “transported” information for obtaining of magnified image of the conductive structures inspected. This work presents a sensor, using MM conical Swiss roll type that allows the propagation of evanescent waves and the electromagnetic images are magnified. The test method can be successfully applied in a variety of applications of maxim importance such as defect/damage detection in materials used in automotive and aviation technologies. Applying this testing method, spatial resolution can be improved.

The proposed model overlooks the contribution of a relational/prosocial dimension to the enjoyment of negative emotion in art reception. Negative experiences have a unique capacity to build social bonds and may also increase motivation to "connect" with the artist. This affiliative motivation ensures that people experience an artwork as more emotional, more intense, more interesting, and ultimately more rewarding.

Histochemical location of key enzyme activities involved in receptivity and self-incompatibility in the olive tree (Olea europaea L.).

Serrano, Irene; Olmedilla, Adela

2012-12-01

Stigma-surface and style enzymes are important for pollen reception, selection and germination. This report deals with the histochemical location of the activity of four basic types of enzyme involved in these processes in the olive (Olea europaea L.). The detection of peroxidase, esterase and acid-phosphatase activities at the surface of the stigma provided evidence of early receptivity in olive pistils. The stigma maintained its receptivity until the arrival of pollen. Acid-phosphatase activity appeared in the style at the moment of anthesis and continued until the fertilization of the ovule. RNase activity was detected in the extracellular matrix of the styles of flowers just before pollination and became especially evident in pistils after self-pollination. This activity gradually decreased until it practically disappeared in more advanced stages. RNase activity was also detected in pollen tubes growing in pollinated pistils and appeared after in vitro germination in the presence of self-incompatible pistils. These findings suggest that RNases may well be involved in intraspecific pollen rejection in olive flowers. To the best of our knowledge this is the first time that evidence of enzyme activity in stigma receptivity and pollen selection has been described in this species.

Theoretical analysis on radiation and reception characteristics of an oblate spheroidal antenna for electron plasma waves

International Nuclear Information System (INIS)

Ohnuki, S.; Adachi, S.; Ohnuma, T.

1978-01-01

The radiation and reception characteristics of the oblate spheroidal antenna for electron plasma waves are theoretically investigated. The analysis is carried out as a boundary-value problem. The formulas for the radiation and reception characteristics such as radiation impedance, electron charge distributions, radiated wave potential, directional properties, and receiving voltage of the oblate spheroidal antenna are analytically obtained. As a result, it is concluded that the radiation and reception characteristics of the antennas are not uniquely determined by k/sub p/a (k/sub p/ is the wave number of an electron plasma wave, and a is the radius of the circular-plate antenna), but are determined by two out of three factors, k/sub p/a, zeta (radius divided by Debye length), and ω/ω/sub p/ (angular signal frequency to angular plasma frequency). This conclusion is in marked contrast to the conventional theory in which the charge distribution on the antenna is assumed a priori as uniform and, thus, the antenna characteristics are uniquely determined by k/sub p/a. It is claimed that the experimental results obtained hitherto support the present new theory

Full Text Available This essay intends to examine the reception of Arthur Schopenhauer’s philosophy in the period betweeen 1818 and 1848, thereby contributing to a demythologization of the luck of the philosopher’s thought on these three decades prior to the beginning of his fame. In order to achieve this, after showing a general picture of the personal myth that has characterised a great part of the historiographic tradition according to which his philosophy would have been ignored or silenced (1, we will present the four key lines of his reception, through the analysis of the news that his contemporaries gave of his philosophy in reviews, manuals of history of philosophy, or encyclopedias. Those four key lines are: a reading of Schopenhauer’s philosophy that stressed on its oriental features (2, an interpretation in an idealistic key which placed a lack of originality in Schopenhauer’s philosophy (3, an academic community that placed it against “the spirit of the times” due to the secondary place of Reason against the Will (4 and finally, the emergence of the first followers of Schopenhauer’s philosophy (5.

2015-04-01

The purpose of this brief report was to determine the effect on receptive identification of photos of a tablet computer-based augmentative and alternative communication (AAC) system with voice output. A multiple baseline single-case experimental design across vocabulary words was implemented. One participant, a preschool-aged boy with autism and little intelligible verbal language, was included in the study. Although a functional relation between the intervention and the dependent variable was not established, the intervention did appear to result in mild improvement for two of the three vocabulary words selected. The authors recommend further investigations of the collateral impacts of AAC on skills other than expressive language.

Differences in early cognitive and receptive-expressive neurodevelopment by ancestry and underlying pathways in Brazil and Argentina.

Science.gov (United States)

Wehby, George L; Trujillo, Antonio J

2017-02-01

We examine disparities in early child cognitive and receptive-expressive skills by ethnic ancestry among infants aged 3-24 months from Brazil and Argentina. We employ unique data on the neurodevelopment of children who were seeking routine well-child care at a set of pediatric clinics in these countries. The sample included children who had normal birth outcomes and no major health complications, allowing us to focus on variation in neurodevelopment among children without major physical health limitations. The physicians attending the pediatric clinics were trained in administering the Bayley Infant Neurodevelopmental Screener, a standardized instrument used to screen an infant's risk of neurodevelopmental problems on various domains of abilities. We evaluate disparities in overall neurodevelopmental scores and risk for neurodevelopmental problems as well as in cognitive functioning and receptive-expressive neurodevelopment. We also examine the extent to which household demographic and socioeconomic characteristics and geographic location explain these disparities. We find large gaps in both cognitive and receptive-expressive neurodevelopment by ancestry. In Brazil, children of African ancestry have lower scores on both cognitive and receptive-expressive domains and on overall neurodevelopment than children of European ancestry. In Argentina, children of Native ancestry have lower scores on these outcomes than children of European ancestry. These gaps however are largely explained by differences in geographic location and household characteristics, highlighting the importance of policies that reduce socioeconomic and geographic disparities in social capital and economic development for eliminating ethnic disparities in infant neurodevelopment.

Merely Misunderstood? Receptive, Expressive, and Pragmatic Language in Young Children With Disruptive Behavior Disorders

Science.gov (United States)

Gremillion, Monica L.; Martel, Michelle M.

2015-01-01

Children with disruptive behavior disorders (DBDs) often seem to have poorer language skills compared to same-age peers; however, language as an early risk factor for DBD has received little empirical attention. The present study provides an empirical examination of associations between normal language variation and DBD by investigating receptive, expressive, and pragmatic language skills and preschool DBD symptoms. The sample consisted of 109 preschoolers ages 3 to 6 (M = 4.77 years, SD = 1.10, 59% boys; 73% with DBD, including oppositional defiant disorder [ODD] and attention-deficit/hyperactivity disorder [ADHD]) along with their primary caregivers, who completed a clinician-administered interview, symptom questionnaires, and a questionnaire measure of pragmatic language, and teacher and/or daycare providers completed symptom questionnaires. Children completed objective tests of receptive and expressive vocabulary. Preschoolers with DBD showed poorer receptive, expressive, and pragmatic skills compared to preschoolers without DBD. Preschoolers with ADHD-only or ADHD+ODD exhibited poorer language skills, compared to ODD and non-DBD groups. Specificity analyses suggested that parent-rated hyperactivity-impulsivity were particularly associated with poorer language skills. Thus, preschoolers with DBD exhibited poorer language skills compared to preschoolers without DBD, and preschoolers with increased hyperactivity-impulsivity exhibited particular problems with language skills. This work suggests the need for early assessment of language in preschoolers, particularly those with ADHD, as well as the possible utility of tailored interventions focused on improving language skills, particularly for those with high hyperactivity-impulsivity.

Chinese paleontology and the reception of Darwinism in early twentieth century.

Science.gov (United States)

Yu, Xiaobo

2017-12-01

The paper examines the social, cultural and disciplinary factors that influenced the reception and appropriation of Darwinism by China's first generation paleontologists. Darwinism was mixed with Social Darwinism when first introduced to China, and the co-option of Darwinian phrases for nationalistic awakening obscured the scientific essence of Darwin's evolutionary theory. First generation Chinese paleontologists started their training in 1910s-1920s. They quickly asserted their professional identity by successfully focusing on morphology, taxonomy and biostratigraphy. Surrounded by Western paleontologists with Lamarckian or orthogenetic leanings, early Chinese paleontologists enthusiastically embraced evolution and used fossils as factual evidence; yet not enough attention was given to mechanistic evolutionary studies. The 1940s saw the beginning of a new trend for early Chinese paleontologists to incorporate more biological and biogeographical components in their work, but external events such as the dominance of Lysenkoism in the 1950s made the Modern Synthesis pass by without being publicly noticed in Chinese paleontology. Characterized by the larger goal of using science for nation building and by the utilitarian approach favoring local sciences, the reception and appropriation of Darwinism by first generation Chinese paleontologists raise important questions for studying the indigenizing efforts of early Chinese scientists to appropriate Western scientific theories.

Aspects of the structure of film expression and anthropological paradigm of films reception in Croatian cinema and TV distribution.

Svilicić, Niksa

2012-09-01

This research paper deals with one part of a comprehensive study called "Causality of narratological-semiotic aspects of the structure of film expression and paradigms of reception of Croatian feature film". It is conceived as a response to the hypothesis that the expression of narrative-semiotic terms correlate with the reception of the Croatian feature film audience and all them leads into a broader holistic i.e. anthropological context.The basic idea of scientific research is to analyze the complete feature productions since Croatian independence 1991 to date, presented at the National Film Festival (film festival in Pula), identify, define and isolate positive social narrative-semiotic stereotypes, which can then serve as a paradigm of better ratings and increase of the currently very low rating of domestic films in Croatian cinemas, as well as TV distribution. In other words, the paper will be analyzed and processed by a range of different effects based on narrative-semiotic, set design and mise-en-scène motives, used in the Croatian feature films since independence to date, that we assume to positively influence the mood of the viewer, and thus increase the rating of the film.

Modern teaching concepts for undergraduate medical students in Germany include problem based learning as a major component of the new licensing regulations for physicians. Here we describe the usage of a web-based virtual outpatient clinic in the teaching curriculum of undergraduate medical students, its effect on learning success, and student reception. Fifth year medial students were requested to examine 7 virtual orthopaedic patients which had been created by the authors using the Inmedea-Simulator. They also had to take a multiple-choice examination on two different occasions and their utilisation of the simulator was analysed subjectively and objectively. One hundred and sixty students took part in the study. The average age was 24.9 years, 60% were female. Most of the participants studied on their own using their private computer with a fast internet-connection at home. The average usage time was 263 min, most of the students worked with the system in the afternoon, although a considerable number used it late in the night. Regarding learning success, we found that the examination results were significantly better after using the system (7.66 versus 8.37, plearning efficacy. The way the system was used by the students emphasises the advantages of the internet-like free time management and the implementation of multimedia-based content.

THE RECEPTION OF A CONTROVERSIAL PLAY – EVANGHELISTII – IN POST-COMMUNIST ROMANIAN SOCIETY

Full Text Available In this paper we intend to present the reception of the play Evangheliştii [The Evangelists] (published in volume in 1993 and represented on stage in 2005 written by Alina Mungiu Pippidi in post-communist Romanian society. In the interpretation of this topic we have considered the author’s artistic goals in relation to the “horizon of expectation” of the Romanian theatre public, as well as to the reaction that critics and institutions outside the world of theatre, such as the Orthodox and Catholic Churches, and local public institutions, had as regards its publication and stage representation. Thus, we have pointed out the clash and the gap that exist between the author’s postmodernist approach to religious faith (i.e. the deconstruction of the Christian ideology and the often wrong reception of the play’s topic coming basically from the Church and in part from the theatre audience. The reception of this play in post-communist Romania is analysed in relation to the rigid, formalist perspective on art shared by an important part of the theatre audience. One of the main conclusions we have drawn is that the openness degree of our society members to the freedom of artistic creation illustrates, in fact, the degree of civilization and, implicitly, of tolerance which we have acquired up to a certain point in time as a society, especially that today our country is no longer totalitarian and, in consequence, no artistic manifestation can be censored by any ideologies coming from the public space.

Environmental enrichment induces powerful changes in the adult cerebral cortex. Studies in primary sensory cortex have observed that environmental enrichment modulates neuronal response strength, selectivity, speed of response, and synchronization to rapid sensory input. Other reports suggest that nonprimary sensory fields are more plastic than primary sensory cortex. The consequences of environmental enrichment on information processing in nonprimary sensory cortex have yet to be studied. Here we examine physiological effects of enrichment in the posterior auditory field (PAF), a field distinguished from primary auditory cortex (A1) by wider receptive fields, slower response times, and a greater preference for slowly modulated sounds. Environmental enrichment induced a significant increase in spectral and temporal selectivity in PAF. PAF neurons exhibited narrower receptive fields and responded significantly faster and for a briefer period to sounds after enrichment. Enrichment increased time-locking to rapidly successive sensory input in PAF neurons. Compared with previous enrichment studies in A1, we observe a greater magnitude of reorganization in PAF after environmental enrichment. Along with other reports observing greater reorganization in nonprimary sensory cortex, our results in PAF suggest that nonprimary fields might have a greater capacity for reorganization compared with primary fields.

Full Text Available The important role of collocation in learners’ language proficiency has been acknowledged widely. In Systemic Functional Linguistics (SFL, collocation is known as one prominent member of the super-ordinate lexical cohesion, which contributes significantly to the textual coherence, together with grammatical cohesion and structural cohesion (Halliday & Hasan, 1985. Collocation is also viewed as the hallmark of truly advanced English learners since the higher the learners’ proficiency is, the more they tend to use collocation (Bazzaz & Samad, 2011; Hsu, 2007; Zhang, 1993. Further, knowledge of collocation is regarded as part of the native speakers’ communicative competence (Bazzaz & Samad, 2011; and lack of the knowledge is the most important sign of foreignness among foreign language learners (McArthur, 1992; McCarthy, 1990. Taking the importance of collocation into account, this study is aimed to shed light on Indonesian EFL learners’ levels of collocational competence. In the study, the collocational competence is restricted to v+n and adj+n of collocation but broken down into productive and receptive competence, about which little work has been done (Henriksen, 2013. For this purpose, 49 second-year students of an English department in a state polytechnic were chosen as the subjects. Two sets of tests (filling in the blanks and multiple-choice were administered to obtain the data of the subjects’ levels of productive and receptive competence and to gain information of which type was more problematic for the learners. The test instruments were designed by referring to Brashi’s (2006 test model, and Koya’s (2003. In the analysis of the data, interpretive-qualitative method was used primarily to obtain broad explanatory information. The data analysis showed that the scores of productive competence were lower than those of receptive competence in both v+n and adj+n collocation. The analysis also revealed that the scores of productive

Models of neural responses to stimuli with complex spatiotemporal correlation structure often assume that neurons are selective for only a small number of linear projections of a potentially high-dimensional input. In this review, we explore recent modeling approaches where the neural response depends on the quadratic form of the input rather than on its linear projection, that is, the neuron is sensitive to the local covariance structure of the signal preceding the spike. To infer this quadratic dependence in the presence of arbitrary (e.g., naturalistic) stimulus distribution, we review several inference methods, focusing in particular on two information theory-based approaches (maximization of stimulus energy and of noise entropy) and two likelihood-based approaches (Bayesian spike-triggered covariance and extensions of generalized linear models). We analyze the formal relationship between the likelihood-based and information-based approaches to demonstrate how they lead to consistent inference. We demonstrate the practical feasibility of these procedures by using model neurons responding to a flickering variance stimulus.

Neurons have been found in the primate brain that respond to objects in specific locations in hand-centered coordinates. A key theoretical challenge is to explain how such hand-centered neuronal responses may develop through visual experience. In this paper we show how hand-centered visual receptive fields can develop using an artificial neural network model, VisNet, of the primate visual system when driven by gaze changes recorded from human test subjects as they completed a jigsaw. A camera mounted on the head captured images of the hand and jigsaw, while eye movements were recorded using an eye-tracking device. This combination of data allowed us to reconstruct the retinal images seen as humans undertook the jigsaw task. These retinal images were then fed into the neural network model during self-organization of its synaptic connectivity using a biologically plausible trace learning rule. A trace learning mechanism encourages neurons in the model to learn to respond to input images that tend to occur in close temporal proximity. In the data recorded from human subjects, we found that the participant's gaze often shifted through a sequence of locations around a fixed spatial configuration of the hand and one of the jigsaw pieces. In this case, trace learning should bind these retinal images together onto the same subset of output neurons. The simulation results consequently confirmed that some cells learned to respond selectively to the hand and a jigsaw piece in a fixed spatial configuration across different retinal views.

Dendro-dendritic interactions between motion-sensitive large-field neurons in the fly.

Science.gov (United States)

Haag, Juergen; Borst, Alexander

2002-04-15

For visual course control, flies rely on a set of motion-sensitive neurons called lobula plate tangential cells (LPTCs). Among these cells, the so-called CH (centrifugal horizontal) cells shape by their inhibitory action the receptive field properties of other LPTCs called FD (figure detection) cells specialized for figure-ground discrimination based on relative motion. Studying the ipsilateral input circuitry of CH cells by means of dual-electrode and combined electrical-optical recordings, we find that CH cells receive graded input from HS (large-field horizontal system) cells via dendro-dendritic electrical synapses. This particular wiring scheme leads to a spatial blur of the motion image on the CH cell dendrite, and, after inhibiting FD cells, to an enhancement of motion contrast. This could be crucial for enabling FD cells to discriminate object from self motion.

We sought to assess physician interest in molecular prognosic testing for patients with early stage colon cancer, and identify factors associated with the likelihood of test adoption. We identified physicians who care for patients with early-stage (pN0) colon cancer patients, mailed them a survey, and analyzed survey responses to assess clinician receptivity to the use of a new molecular test (GUCY2C) that identifies patients at risk for recurrence, and clinician readiness to act on abnormal test results. Of 104 eligible potential respondents, 41 completed and returned the survey. Among responding physicians, 56 % were receptive to using the new prognostic test. Multivariable analyses showed that physicians in academic medical centers were significantly more receptive to molecular test use than those in non-academic settings. Forty-one percent of respondents were ready to act on abnormal molecular test results. Physicians who viewed current staging methods as inaccurate and were confident in their capacity to incorporate molecular testing in practice were more likely to say they would act on abnormal test results. Physician receptivity to molecular diagnostic testing for early-stage colon cancer patients is likely to be influenced by practice setting and perceptions related to delivering quality care to patients.

Full Text Available Reception staff loyalty is much influenced by several factors, one of them is job satisfaction. Employee job satisfaction plays important role in creating employee loyalty. For hoteliers who serve as provider of accommodation services, the demand for the creation of quality human resources is maximum achievement. One of the important section in the front office is receptionist. Today, hoteliers pay very close attention because the employee turnover will certainly affect the consistency of services offered by the hotel. Therefore, the hotel is getting active in increasing the satisfaction of its staff in order to minimize employee turnover especially in a very important role such the receptionist. Although the validity of the relationship between job satisfaction and reception staff loyalty is still an exciting debate, the result of the research conducted in the Hotel X is expected to help increase employee satisfaction in order to create quality of life that will improve labor productivity.

Discrimination related to gender identity may directly influence vulnerability to HIV through increased exposure to unprotected receptive anal intercourse (URAI). Little is known about the relationship between gender-based discrimination (GBD) and URAI with stable partners among transgender women. This mixed-methods research began with a cross-sectional survey conducted between 2014 and 2016 with transgender women in Salvador, the capital city in one of the poorest regions in Brazil. Respondent-driven sampling was used to recruit the study population. GBD was defined through Latent Class Analysis. Additionally, 19 semi-structured interviews with participants were transcribed and analyzed through thematic content analysis. URAI with stable partners was commonly reported (37.3%). GDB was positively associated with URAI among stable partners (OR = 6.47; IC 95%: 1.67-25.02). The analysis of the interviews illustrated how GBD impacted transgender women in diverse ways. Experiences with GBD perpetrated by the family often initiated a trajectory of economic vulnerability that led many to engage in survival sex work. The constant experience with GBD contributed to participants feeling an immense sense of trust with their stable partners, ultimately diminished their desire to use condoms. Further, the high frequency of GBD contributed to poor mental health overall, though some participants said engagement in transgender advocacy efforts provided a vital source of resilience and support. Our mixed-method study capitalizes upon the strengths of diverse data sets to produce a holistic understanding of GBD and URAI with stable partners. Furthermore, by confirming the association between greater GBD and URAI, we have demonstrated how GBD can impact condom negotiation in diverse relationships.

Combined free-stream disturbance measurements and receptivity studies in hypersonic wind tunnels were conducted by means of a slender wedge probe and direct numerical simulation. The study comprises comparative tunnel noise measurements at Mach 3, 6 and 7.4 in two Ludwieg tube facilities and a shock tunnel. Surface pressure fluctuations were measured over a wide range of frequencies and test conditions including harsh test environments not accessible to measurement techniques such as pitot probes and hot-wire anemometry. Quantitative results of the tunnel noise are provided in frequency ranges relevant for hypersonic boundary layer transition. In combination with the experimental studies, direct numerical simulations of the leading-edge receptivity to fast and slow acoustic waves were performed for the slender wedge probe at conditions corresponding to the experimental free-stream conditions. The receptivity to fast acoustic waves was found to be characterized by an early amplification of the induced fast mode. For slow acoustic waves an initial decay was found close to the leading edge. At all Mach numbers, and for all considered frequencies, the leading-edge receptivity to fast acoustic waves was found to be higher than the receptivity to slow acoustic waves. Further, the effect of inclination angles of the acoustic wave with respect to the flow direction was investigated. The combined numerical and experimental approach in the present study confirmed the previous suggestion that the slow acoustic wave is the dominant acoustic mode in noisy hypersonic wind tunnels.

Fagan, Mary K; Pisoni, David B

2010-01-01

This study investigated receptive vocabulary delay in deaf children with cochlear implants. Participants were 23 children with profound hearing loss, ages 6-14 years, who received a cochlear implant between ages 1.4 and 6 years. Duration of cochlear implant use ranged from 3.7 to 11.8 years. Peabody Picture Vocabulary Test, Third Edition (PPVT-III) data were analyzed first by examining children's errors for evidence of difficulty in specific lexical content areas, and second by calculating standard scores with reference to hearing age (HA) (i.e., chronological age [CA]--age at implantation) rather than CA. Participants showed evidence of vocabulary understanding across all PPVT-III content categories with no strong evidence of disproportionate numbers of errors in any specific content area despite below-average mean standard scores. However, whereas mean standard scores were below the test mean established for hearing children when based on CA, they were within the average range for hearing children when calculated based on HA. Thus, children's vocabulary knowledge was commensurate with years of cochlear implant experience, providing support for the role of spoken language experience in vocabulary acquisition.

Music, Brain Plasticity and the Resilience: the Pillars of New Receptive Therapy.

This paper describes a new type of receptive music therapy which aims to build the patients' psychological resilience by increasing the levels of dopamine, serotonin and oxytocin in order to increase standard psychopharmacological treatment efficiency. Previous research concerning the musically induced production of the two neurotransmitters and a hormone is discussed and reviewed. Based upon the existent studies concerning the influence of music on dopamine, serotonin and oxytocin induction, a new design of specific music features for this purpose is proposed and elaborated upon. The music features are numerically described using Music Information Retrieval software in order to objectivise the otherwise intuitively chosen music elements such as event density (number of notes started in one second of time), tempo, harmonic rhythm (number of harmonies changes in one second), dynamics, key changes and roughness coefficient (level of sensory dissonance). Finally, the new concept of resilience enhancing therapy is proposed and defined using the music features described above.

Divine Love: The Reception of Leda and the Swan Myth in Works by Jewish and Arab Israeli Artists - Contexts and Meanings

Directory of Open Access Journals (Sweden)

Nava Sevilla Sadeh

2014-09-01

Full Text Available The motif of the abduction of a woman is one of the most frequent in Ancient Greek and Roman art. Abductions in mythology are generally portrayed as carried out by a god disguised as a human or an animal, such as Zeus who, in the form of a bull, golden rain or a swan, seduces a beautiful young maiden. These myths have been interpreted from different viewpoints, such as gender, social, political and philosophical. One of the most frequent myths of abduction is that of Leda and the Swan, which appears in both Greek and Roman painting and sculpture. This theme has found many echoes in contemporary Israeli art, and constitutes the case study for this discussion, which belongs to the field of Classical Reception studies. The interpretations of this myth are diverse, ranging from a socio-gender context, to post-colonialism and its relevance to the local situation; to subversives, concerning tradition versus contemporary culture; to emotionality and romantic suffering; and to love as phantasmagoria. These varied interpretations will be examined in the following analysis in light of both ancient concepts and contemporary outlooks, based on literary and philosophical sources.

2016-01-01

When describing the anisotropic evolution of microstructures in solids using phase-field models, the anisotropy of the crystalline phases is usually introduced into the interfacial energy by directional dependencies of the gradient energy coefficients. We consider an alternative approach based on a wavelet analogue of the Laplace operator that is intrinsically anisotropic and linear. The paper focuses on the classical coupled temperature/Ginzburg--Landau type phase-field model for dendritic growth. For the model based on the wavelet analogue, existence, uniqueness and continuous dependence on initial data are proved for weak solutions. Numerical studies of the wavelet based phase-field model show dendritic growth similar to the results obtained for classical phase-field models.

Hosting a reception for prospective interns the evening before the interview has become a well-established expectation. It is thought that these initial impressions significantly influence the ranking process. Despite these well-held beliefs, there has been a paucity of studies exploring the preinterview reception. A survey tool was created and piloted to ensure validity. The survey was then administered to a fourth-year class of allopathic medical students immediately after interviews but before Match Day. A university, teaching hospital. Fourth-year allopathic medical students. The response rate was 100% (n = 69). Ninety-six percent of programs hosted an event. Although these events were minimally stressful (86%), the same percent felt that not attending would limit their knowledge of the program, and 66% felt that it would negatively affect their application. Forty percent believe this event to be extremely important to residency programs in selecting interns. Ninety-five percent are attended by residents only, and approximately half were at a casual restaurant. Most applicants (97%) never paid for their own meal, and 69% felt that if they did, it would leave a negative impression of the program. Candidates believe the preinterview reception is important in the selection process, that failing to attend would negatively affect their application, and provides insight about the program. Alcohol is often provided but rarely has a negative effect. Applicants prefer an informal setting with unfettered interactions with the residents. © 2013 Association of Program Directors in Surgery.

Pittman, A L; Lewis, D E; Hoover, B M; Stelmachowicz, P G

2005-12-01

This study examined rapid word-learning in 5- to 14-year-old children with normal and impaired hearing. The effects of age and receptive vocabulary were examined as well as those of high-frequency amplification. Novel words were low-pass filtered at 4 kHz (typical of current amplification devices) and at 9 kHz. It was hypothesized that (1) the children with normal hearing would learn more words than the children with hearing loss, (2) word-learning would increase with age and receptive vocabulary for both groups, and (3) both groups would benefit from a broader frequency bandwidth. Sixty children with normal hearing and 37 children with moderate sensorineural hearing losses participated in this study. Each child viewed a 4-minute animated slideshow containing 8 nonsense words created using the 24 English consonant phonemes (3 consonants per word). Each word was repeated 3 times. Half of the 8 words were low-pass filtered at 4 kHz and half were filtered at 9 kHz. After viewing the story twice, each child was asked to identify the words from among pictures in the slide show. Before testing, a measure of current receptive vocabulary was obtained using the Peabody Picture Vocabulary Test (PPVT-III). The PPVT-III scores of the hearing-impaired children were consistently poorer than those of the normal-hearing children across the age range tested. A similar pattern of results was observed for word-learning in that the performance of the hearing-impaired children was significantly poorer than that of the normal-hearing children. Further analysis of the PPVT and word-learning scores suggested that although word-learning was reduced in the hearing-impaired children, their performance was consistent with their receptive vocabularies. Additionally, no correlation was found between overall performance and the age of identification, age of amplification, or years of amplification in the children with hearing loss. Results also revealed a small increase in performance for both

Full Text Available Objectives: Since 2009, the University of Cologne has been developing a longitudinal curriculum for teaching social and communicative skills to dental students (LSK-Dent based on the recommendations of the Association for Dental Education in Europe (ADEE. As a part of this curriculum it was considered to develop a reception service in the undergraduate treatment courses of the Department of Operative Dentistry and Periodontology involving the organizational and administrative handling of the patients by the students. Students should gain an insight into everyday practice and the reception service should function as a learning environment for social und communicative competences. This article introduces the LSK-Dent project, the implementation of the reception service and presents initial evaluation results.Methods: Patients (n=575 and students (n=53 filled out a questionnaire. Additionally, four semi-structured interviews with students were conducted.Results: The reception service was successfully implemented and endorsed by the students. First indications suggest that the reception service was well received by students as a learning environment for social und communicative competences and viewed as an opportunity to gain an insight into everyday practice.Conclusion: The reception service is an innovative addition to the treatment courses and an example for transforming an already existing reality in a course into a new learning environment for students. To what extent the implementation of reflexive elements can increase the subjectively perceived additional benefit by students, has to be addressed in further studies.

Music therapy is demonstrated to be effective to relieve the agitation among people with dementia, but the comparative effectiveness of methods of music engagement for people with dementia is uncertain. To evaluate the effects on cognitive functions and behavioral symptoms between interactive and receptive music therapies for people with dementia. Prospective studies evaluating interactive and receptive music therapies were identified from the OVID databases, included MEDLINE, EMBASE, PsycINFO, and CINAHL. Supplementary search was conducted in Google Scholar. The primary outcome focused on cognitive function; the secondary outcomes were apathy, anxiety, depressive symptoms, agitation, and other behavioral problems. All outcomes were measured by the standard assessment tools. The heterogeneity of studies was examined, and the effects were pooled by meta-analysis. Quality of studies and risk of bias were assessed. Thirty-eight trials involving 1418 participants with dementia were included. The mean age ranged from 75 to 90 years, and the percentage of male participants ranged from 6% to 83%. No significant difference was found between participants receiving interactive or receptive music therapy and usual care in cognitive function; the mean difference (MD) of Mini-Mental State Examination was 0.18 [95% confidence interval (CI) -1.34 to 1.69], and -0.15 (95% CI -0.55 to 0.25), respectively. Participants with receptive music therapy had significant decrease in agitation (Cohen-Mansfield Agitation Inventory: MD = -7.99, 95% CI -5.11 to -0.87) and behavioral problems (Neuropsychiatric Inventory: MD = -3.02 95% CI -5.90 to -0.15) compared to usual care, while no significant difference was found between interactive music therapy and usual care in behavioral problems and psychiatric symptoms. This study demonstrated that receptive music therapy could reduce agitation, behavioral problems, and anxiety in older people with dementia, and appears to be more

The reception of Eugen Bleuler in British psychiatry, 1892-1954.

LENUS (Irish Health Repository)

Dalzell, Thomas

2012-02-01

This article draws on over 60 years of British medical journals and psychiatry textbooks to indicate the chronological stages of the reception of Eugen Bleuler in British psychiatry. Bleuler was already well known in Britain before his schizophrenia book appeared, with the journals containing numerous references, mainly positive, to his work. The psychiatry textbooks, however, were slower to integrate his contribution. This paper argues that this was not due to Bleuler\\'s placing Freud on a par with Kraepelin, but because of the early negative reaction to Kraepelin\\'s dementia praecox concept, despite Bleuler\\'s wider and less ominous conception of the illness.

Personal suicidality in reception and identification with suicidal film characters.

The authors investigated the impact of suicidality on identity work during film exposure. Adults with low suicidality (n = 150) watched either It's My Party or The Fire Within, censored versions of these films not depicting the suicide, or the control film that concluded with a non-suicidal death. Baseline suicidality was measured with questionnaires before the movie. Identity work and identification with the protagonist were measured after the movie. Suicidality was directly associated with identity work during film dramas depicting suicide methods. The reception of suicide-related media content seems to partially depend on personal suicidality. Potential implications for suicide prevention are discussed.

[Introducing computer units into the reception office as part of the Vrapce Psychiatric Hospital Information System].

Majdancić, Zeljko; Jukić, Vlado; Bojić, Miroslav

2005-01-01

Computerized medical record has become a necessity today, because of both the amount of present-day medical data and the need of better handling and processing them. In more than 120 years of the Vrapce Psychiatric Hospital existence, the most important changes in the working concept of the reception office took place when computer technology was introduced into the routine use. The reception office of the Hospital is the vital place where administrative activities intersect with medical care for a patient presenting to the Hospital. The importance of this segment of the Hospital is emphasized by the fact that the reception office is in function and at patients' disposition round-the-clock, for 365 days a year, with great frequency of patients. The shift from the established way of registering medical data on patient admission in handwriting or, later, typescript, to computer recording was a challenging and demanding task (from the aspects of hardware, software, network, education) for the development team as well as for the physicians because it has changed the concept (logic of the working process) of previous way of collecting the data from the patient (history, status, diagnostic procedures, therapy, etc.). The success in the development and implementation of this project and the confirmation of its usefulness during the four-year practice at Vrapce Psychiatric Hospital are best illustrated by the fact that other psychiatric hospitals in Croatia have already introduced or are introducing it in their daily practice.

The Reception of Ernest Hemingway in Iran after the Islamic Revolution: A study of The Old Man and the Sea and To Have and Have Not

Directory of Open Access Journals (Sweden)

Alireza Anushiravani

2017-04-01

Full Text Available This article investigates how the literary reception of Ernest Hemingway in Iran in the first two decades after the Islamic Revolution is formed by cultural and ideological implications. The theoretical framework of this study is based on S.S. Prawer and Roger Asselineau’s notion of reception theory as a branch of study in comparative literature. The methodology entails a chronological study of translations, and cinematic adaptations of the author’s oeuvres. This study devotes itself to the study of the two most reprinted and translated works which depict a huge difference in the number of translations and reprints compared to Hemingway’s other works. As Such, the following outcomes are deliberated: besides the international fame of Hemingway, his continuing success in Iran can be related to the ideology of the translator, and the director, who deploy Hemingway’s novels as a prism to reflect Iranians’ stoic perseverance and mythical desire for freedom and fight against despotism as manifested in the legend of Jamshid. Hemingway’s code hero, undergoing stoic perseverance in hardship and war embody Iranians’ passage through a turbulent historical event after Revolution. Struggling with unemployment, war, and frustrated hopes, Iranians find Hemingway’s novels as a way to cope with arising problems during and after war. This article also explicates why reception of this particular work in Iran differs from its universal trend.

Generation and reception of spread-spectrum signals

Science.gov (United States)

Moser, R.

1983-05-01

The term 'spread-spectrum' implies a technique whereby digitized information is added to a pseudo-random number sequence and the resultant bit stream changes some parameter of the carrier frequency in discrete increments. The discrete modulation of the carrier frequency is usually realized either as a multiple level phase shift keyed or frequency shift keyed signal. The resultant PSK-modulated frequency spectrum is referred to as direct sequence spread-spectrum, whereas the FSK-modulated carrier frequency is referred to as a frequency hopped spread spectrum. These can be considered the major subsets of the more general term 'spread-spectrum'. In discussing signal reception, it is pointed out that active correlation methods are used for channel synchronization when the psuedo random sequences are long or when the processing gain is large, whereas the passive methods may be used for either short pseudo-random noise generation codes or to assist in attaining initial synchronization in long sequence spread-spectrum systems.

Full Text Available Nowadays, only companies that are adaptable and flexible in their structure and processes can survive. The basis for a motivated company aiming for peak performance is organisational innovation. Hungary is one of the less innovative countries in Europe. Only organisations that can integrate new solutions smoothly into their everyday operations will remain truly competitive. The Government of Hungary, in its Partnership Agreement with the European Union, set out the goals for improving and supporting the adaptability of enterprises, the promotion of flexible and family-friendly workplace practices and services, and the employment of women with young children. The aim of this study is to demonstrate, through a Hungarian example, the receptiveness of Hungarian small and medium-sized enterprises to flexible forms of employment. The effect of flexible employment on economic adaptability and competitiveness through workforce efficiency and retention is examined. Its aim is the raise the awareness of options to increase employment among Hungarian SME managers.

Atypical cortical language organization in epilepsy patients: evidence for divergent hemispheric dominance for receptive and expressive language function.

Eliashiv, Dawn S; Kurelowech, Lacey; Quint, Patti; Chung, Jeffrey M; Otis, Shirley M; Gage, Nicole M

2014-06-01

The central goal of presurgical language mapping is to identify brain regions that subserve cortical language function to minimize postsurgical language deficits. Presurgical language mapping in patients with epilepsy presents a key challenge because of the atypical pattern of hemispheric language dominance found in this population, with higher incidences of bilateral and right-biased language dominance than typical. In this prospective study, we combine magnetoencephalography with a panel of tasks designed to separately assess receptive and expressive function to provide a sensitive measure of language function in 15 candidates for resective surgery. We report the following: 4 of 15 patients (27%) showed left hemisphere dominance across all tasks, 4 of 15 patients (27%) showed right hemisphere dominance across all tasks, and 7 of 15 (46%) showed discordant language dominance, with right-dominant receptive and left-dominant expressive language. All patients with discordant language dominance showed this right-receptive and left-expressive pattern. Results provide further evidence supporting the importance of using a panel of tasks to assess separable aspects of language function. The clinical relevance of the findings is discussed, especially about current clinical operative measures for assessing language dominance, which use single hemisphere procedure (intracarotid amobarbital procedure and awake intraoperative stimulation) for determining language laterality.

The relationship between phonological short-term memory, receptive vocabulary, and fast mapping in children with specific language impairment.

Jackson, Emily; Leitao, Suze; Claessen, Mary

2016-01-01

Children with specific language impairment (SLI) often experience word-learning difficulties, which are suggested to originate in the early stage of word learning: fast mapping. Some previous research indicates significantly poorer fast mapping capabilities in children with SLI compared with typically developing (TD) counterparts, with a range of methodological factors impacting on the consistency of this finding. Research has explored key issues that might underlie fast mapping difficulties in children with SLI, with strong theoretical support but little empirical evidence for the role of phonological short-term memory (STM). Additionally, further research is required to explore the influence of receptive vocabulary on fast mapping capabilities. Understanding the factors associated with fast mapping difficulties that are experienced by children with SLI may lead to greater theoretically driven word-learning intervention. To investigate whether children with SLI demonstrate significant difficulties with fast mapping, and to explore the related factors. It was hypothesized that children with SLI would score significantly lower on a fast mapping production task compared with TD children, and that phonological STM and receptive vocabulary would significantly predict fast mapping production scores in both groups of children. Twenty-three children with SLI (mean = 64.39 months, SD = 4.10 months) and 26 TD children (mean = 65.92 months, SD = 2.98) were recruited from specialist language and mainstream schools. All participants took part in a unique, interactive fast-mapping task whereby nine novel objects with non-word labels were presented and production accuracy was assessed. A non-word repetition test and the Peabody Picture Vocabulary Test-Fourth Edition (PPVT-IV) were also administered as measures of phonological STM capacity and receptive vocabulary, respectively. Results of the fast-mapping task indicated that children with SLI had significantly poorer fast

2017-11-01

The research note presents the initial reception of psychoanalytic theory by psychiatric physicians in Rio de Janeiro in the first decades of the twentieth century before it became an institutionalized scientific tool. To understand the specificities of its reception, it examines, from the standpoint of the circulation of scientific knowledge and the process of adaptation to the local context, how the perceptions of psychiatrists regarding psychoanalytic theory were embedded in the then prevailing scientific theories and assumptions, initially in the dabates on the hysteria and nervousness categories. It also suggests that psychoanalytic theory should be used to deeply understand other debates of the time, such as sexuality and nervous diseases.

Facilitation of receptive and productive foreign vocabulary learning using the keyword method: the role of image quality.

Science.gov (United States)

Beaton, Alan A; Gruneberg, Michael M; Hyde, Christopher; Shufflebottom, Alex; Sykes, Robert N

2005-07-01

Ellis and Beaton (1993a) reported that the keyword method of learning enhanced memory of foreign vocabulary items when receptive learning was measured. However, for productive learning, rote repetition was superior to the keyword method. The first two experiments reported here show that, in comparison with rote repetition, both receptive and productive learning can be enhanced by the keyword method, provided that the quality of the keyword images is adequate. In a third experiment using a subset of words from Ellis and Beaton (1993a), the finding they reported, that for productive learning rote repetition was superior to the keyword method, was reversed. The quality of keyword images will vary from study to study and any generalisation regarding the efficacy of the keyword method must take this into account.

Even though light field technology was first invented more than 50 years ago, it did not gain popularity due to the limitation imposed by the computation technology. With the rapid advancement of computer technology over the last decade, the limitation has been uplifted and the light field technology quickly returns to the spotlight of the research stage. In this paper, PBRT (Physical Based Rendering Tracing) was introduced to overcome the limitation of using traditional optical simulation approach to study the light field camera technology. More specifically, traditional optical simulation approach can only present light energy distribution but typically lack the capability to present the pictures in realistic scenes. By using PBRT, which was developed to create virtual scenes, 4D light field information was obtained to conduct initial data analysis and calculation. This PBRT approach was also used to explore the light field data calculation potential in creating realistic photos. Furthermore, we integrated the optical experimental measurement results with PBRT in order to place the real measurement results into the virtually created scenes. In other words, our approach provided us with a way to establish a link of virtual scene with the real measurement results. Several images developed based on the above-mentioned approaches were analyzed and discussed to verify the pros and cons of the newly developed PBRT based light field camera technology. It will be shown that this newly developed light field camera approach can circumvent the loss of spatial resolution associated with adopting a micro-lens array in front of the image sensors. Detailed operational constraint, performance metrics, computation resources needed, etc. associated with this newly developed light field camera technique were presented in detail.

This study demonstrates the potential of racial identity to moderate how gain and loss-framed messaging, as well as culturally-targeted messaging, can affect receptivity to preventive health screening. African-Americans (N = 132) who were noncompliant with recommended colorectal cancer (CRC) screening completed a measure of racial identity centrality-encompassing the extent to which racial identity is a core component of self-concept-and then participated in an online education module about CRC screening, during which either gain or loss-framed messaging was introduced. Half of African-Americans were also exposed to a culturally-targeted self-help message about preventing CRC. Theory of Planned Behavior measures of attitudes, normative beliefs, perceived behavioral control, and intentions to obtain a CRC screen served as outcomes. Results confirmed that effects of messaging on receptivity to CRC screening depended on racial identity. Among low racial identity African Americans, gain-framed messaging most effectively increased normative beliefs about obtaining CRC screening, whereas among high racial identity African Americans loss-framed messaging was most compelling. However, these effects most strongly emerged when culturally-targeted self-help messaging was included. We discuss implications for health disparities theory and research, including a potential to simultaneously deploy culturally-targeted and tailored messaging based on racial identity.

2015-03-01

The aim of the present work was to examine adult smokers' awareness of and receptivity to an electronic nicotine delivery system (ENDS) television advert, and whether viewing the advert influenced urge to smoke and intention to try ENDS. A television advert for ENDS brand blu eCigs was shown to an online convenience sample of 519 Florida adult smokers. We measured current smokers' awareness of and receptivity to the advert, and whether seeing the advert influenced their thoughts about smoking or quitting, urge to smoke and intention to try ENDS. Results were stratified by prior ENDS use. Approximately 62.3% of current smokers were aware of the advert. Smokers found the advert informative (73.8%), attention grabbing (67.5%) and innovative (64.5%), with prior ENDS users rating the advert more favourably than non-users. Seeing the advert elicited an urge to smoke (mean 42.1, SD=1.9) and thoughts about smoking cigarettes (75.8%) as well as quitting (74.6%). Prior END users were significantly more likely than non-users to report thinking about smoking cigarettes after seeing the advert (Padvertising and examine how exposure to ENDS adverts influences smokers' use of ENDS, dual use with cigarettes and cessation behaviour.

The role of the temperature factor in the mechanism of reception of the CO2 laser low-power infrared (IR) radiation (λ = 10.6 μm) by a sensory neuron membrane has been studied. Organotypic embryonic tissue culture has been used to measure and estimate the temperature of a sensory ganglia monolayer exposed to radiation at different energy densities. The effects of tissue exposure to low-power IR radiation have been investigated. It has been found that inhibition of tissue growth by radiation of low energy density (10-14-10-10 J/cm2) is replaced by tissue growth (10-7-10-4 J/cm2), and again followed by inhibition in the range of 0.1-6 J/cm2. A statistically significant specific reaction to nonthermal radiation has been detected at the radiation power density of 3 × 10-10 J/cm2, which is due to activation of the Na+,K+-ATPase transducer function. The mechanisms of interaction of IR radiation with embryonic nerve tissue have been considered. Low-power IR radiation with the wavelength of 10.6 μm has been demonstrated to specifically activate a novel signal transducer function of the sodium pump, which controls the reception of nonthermal IR radiation in the energy density range of 10-14 to 10-10 J/cm2.

Receptive fields for smooth pursuit eye movements and motion perception.

Debono, Kurt; Schütz, Alexander C; Spering, Miriam; Gegenfurtner, Karl R

2010-12-01

Humans use smooth pursuit eye movements to track moving objects of interest. In order to track an object accurately, motion signals from the target have to be integrated and segmented from motion signals in the visual context. Most studies on pursuit eye movements used small visual targets against a featureless background, disregarding the requirements of our natural visual environment. Here, we tested the ability of the pursuit and the perceptual system to integrate motion signals across larger areas of the visual field. Stimuli were random-dot kinematograms containing a horizontal motion signal, which was perturbed by a spatially localized, peripheral motion signal. Perturbations appeared in a gaze-contingent coordinate system and had a different direction than the main motion including a vertical component. We measured pursuit and perceptual direction discrimination decisions and found that both steady-state pursuit and perception were influenced most by perturbation angles close to that of the main motion signal and only in regions close to the center of gaze. The narrow direction bandwidth (26 angular degrees full width at half height) and small spatial extent (8 degrees of visual angle standard deviation) correspond closely to tuning parameters of neurons in the middle temporal area (MT).

Non-centered spike-triggered covariance analysis reveals neurotrophin-3 as a developmental regulator of receptive field properties of ON-OFF retinal ganglion cells.

Directory of Open Access Journals (Sweden)

Donald R Cantrell

2010-10-01

Full Text Available The functional separation of ON and OFF pathways, one of the fundamental features of the visual system, starts in the retina. During postnatal development, some retinal ganglion cells (RGCs whose dendrites arborize in both ON and OFF sublaminae of the inner plexiform layer transform into RGCs with dendrites that monostratify in either the ON or OFF sublamina, acquiring final dendritic morphology in a subtype-dependent manner. Little is known about how the receptive field (RF properties of ON, OFF, and ON-OFF RGCs mature during this time because of the lack of a reliable and efficient method to classify RGCs into these subtypes. To address this deficiency, we developed an innovative variant of Spike Triggered Covariance (STC analysis, which we term Spike Triggered Covariance - Non-Centered (STC-NC analysis. Using a multi-electrode array (MEA, we recorded the responses of a large population of mouse RGCs to a Gaussian white noise stimulus. As expected, the Spike-Triggered Average (STA fails to identify responses driven by symmetric static nonlinearities such as those that underlie ON-OFF center RGC behavior. The STC-NC technique, in contrast, provides an efficient means to identify ON-OFF responses and quantify their RF center sizes accurately. Using this new tool, we find that RGCs gradually develop sensitivity to focal stimulation after eye opening, that the percentage of ON-OFF center cells decreases with age, and that RF centers of ON and ON-OFF cells become smaller. Importantly, we demonstrate for the first time that neurotrophin-3 (NT-3 regulates the development of physiological properties of ON-OFF center RGCs. Overexpression of NT-3 leads to the precocious maturation of RGC responsiveness and accelerates the developmental decrease of RF center size in ON-OFF cells. In summary, our study introduces STC-NC analysis which successfully identifies subtype RGCs and demonstrates how RF development relates to a neurotrophic driver in the retina.

Wavelet-Based Quantum Field Theory

Full Text Available The Euclidean quantum field theory for the fields $phi_{Delta x}(x$, which depend on both the position $x$ and the resolution $Delta x$, constructed in SIGMA 2 (2006, 046, on the base of the continuous wavelet transform, is considered. The Feynman diagrams in such a theory become finite under the assumption there should be no scales in internal lines smaller than the minimal of scales of external lines. This regularisation agrees with the existing calculations of radiative corrections to the electron magnetic moment. The transition from the newly constructed theory to a standard Euclidean field theory is achieved by integration over the scale arguments.

2007-01-01

Field emitters of vertical carbon fibers on a silicon substrate are fabricated by catalytic chemical vapor deposition. After an ageing process of 150 min, field emission measurement of the fibers is carried out in a vacuum chamber with a base pressure of 5.0 x 10 -4 Pa. The experimental results display that field emission performance of the carbon fibers depends strongly on the vacuum level during the experiments. After the field emission measurement, damage to the carbon fiber field emitters is observed from the scanning electron microscopic images

Tobacco marketing is a contributing factor to adolescent smoking, and now targeting adolescents in low- and middle-income countries. Especially, promotional items with tobacco brand logos have a great impact on adolescent smoking. The authors evaluated whether receptivity to tobacco marketing is associated with susceptibility to smoking among non-smoking male students in Lao PDR. The authors conducted a cross-sectional study with self-administered questionnaires among 526 non-smoking male students in grades 8th and 11th (aged 12-19 years) in Vientiane Capital, Lao PDR. The authors investigated receptivity to tobacco marketing by three measurements: awareness of tobacco marketing, recognition of tobacco marketing messages and owning/being willing to use promotional items. The authors then conducted multiple logistic regression analysis to determine whether marketing receptivity had an independent association with smoking susceptibility, which is defined as the absence of a firm decision not to smoke. About 20% of the participants were susceptible to smoking. Recognition of marketing messages was significantly associated with susceptibility to smoking (OR=1.76, 95% CI 1.01 to 3.08), as was any owning/being willing to use promotional items with recognition of marketing messages (OR=2.39, 95% CI 1.34 to 4.24). In contrast, any owning/being willing to use promotional items without any recognition of marketing messages was not significantly associated with susceptibility. A significant association was detected between smoking susceptibility and marketing receptivity, which has been little explored in previous research in low-income countries. Owning/being willing to use promotional items was associated with smoking susceptibility only when there is also recognition of marketing messages.

Early development and orientation of the acoustic funnel provides insight into the evolution of sound reception pathways in cetaceans.

Directory of Open Access Journals (Sweden)

Maya Yamato

Full Text Available Whales receive underwater sounds through a fundamentally different mechanism than their close terrestrial relatives. Instead of hearing through the ear canal, cetaceans hear through specialized fatty tissues leading to an evolutionarily novel feature: an acoustic funnel located anterior to the tympanic aperture. We traced the ontogenetic development of this feature in 56 fetal specimens from 10 different families of toothed (odontocete and baleen (mysticete whales, using X-ray computed tomography. We also charted ear ossification patterns through ontogeny to understand the impact of heterochronic developmental processes. We determined that the acoustic funnel arises from a prominent V-shaped structure established early in ontogeny, formed by the malleus and the goniale. In odontocetes, this V-formation develops into a cone-shaped funnel facing anteriorly, directly into intramandibular acoustic fats, which is likely functionally linked to the anterior orientation of sound reception in echolocation. In contrast, the acoustic funnel in balaenopterids rotates laterally, later in fetal development, consistent with a lateral sound reception pathway. Balaenids and several fossil mysticetes retain a somewhat anteriorly oriented acoustic funnel in the mature condition, indicating that a lateral sound reception pathway in balaenopterids may be a recent evolutionary innovation linked to specialized feeding modes, such as lunge-feeding.

The auditory anatomy of the minke whale (Balaenoptera acutorostrata): a potential fatty sound reception pathway in a baleen whale.

Cetaceans possess highly derived auditory systems adapted for underwater hearing. Odontoceti (toothed whales) are thought to receive sound through specialized fat bodies that contact the tympanoperiotic complex, the bones housing the middle and inner ears. However, sound reception pathways remain unknown in Mysticeti (baleen whales), which have very different cranial anatomies compared to odontocetes. Here, we report a potential fatty sound reception pathway in the minke whale (Balaenoptera acutorostrata), a mysticete of the balaenopterid family. The cephalic anatomy of seven minke whales was investigated using computerized tomography and magnetic resonance imaging, verified through dissections. Findings include a large, well-formed fat body lateral, dorsal, and posterior to the mandibular ramus and lateral to the tympanoperiotic complex. This fat body inserts into the tympanoperiotic complex at the lateral aperture between the tympanic and periotic bones and is in contact with the ossicles. There is also a second, smaller body of fat found within the tympanic bone, which contacts the ossicles as well. This is the first analysis of these fatty tissues' association with the auditory structures in a mysticete, providing anatomical evidence that fatty sound reception pathways may not be a unique feature of odontocete cetaceans.

Zhang, Jin; Walker, William B; Wang, Guirong

2015-01-01

Male moths detect and find their mates using species-specific sex pheromones emitted by conspecific females. Olfaction plays a vital role in this behavior. Since the first discovery of an insect sex pheromone from the silkmoth Bombyx mori, great efforts have been spent on understanding the sensing of the pheromones in vivo. Much progress has been made in elucidating the molecular mechanisms that mediate chemoreception in insects in the past few decades. In this review, we focus on pheromone reception and detection in moths, from the molecular to the behavioral level. We trace the information pathway from the capture of pheromone by male antennae, binding and transportation to olfactory receptor neurons, receptor activation, signal transduction, molecule inactivation, through brain processing and behavioral response. We highlight the impact of recent studies and also provide our insights into pheromone processing. © 2015 Elsevier Inc. All rights reserved.

Collection of genetic biospecimens as part of critical illness investigations is increasingly commonplace. Oversight bodies vary in restrictions imposed on genetic research, introducing inconsistencies in study design, potential for sampling bias, and the possibility of being overly prohibitive of this type of research altogether. We undertook this study to better understand whether restrictions on genetic data collection beyond those governing research on cognitively intact subjects reflect the concerns of surrogates for critically ill patients. We analyzed survey data collected from 1,176 patients in nonurgent settings and 437 surrogates representing critically ill adults. Attitudes pertaining to genetic data (familiarity, perceptions, interest in participation, concerns) and demographic information were examined using univariate and multivariate techniques. We explored differences among respondents who were receptive (1,333) and nonreceptive (280) to genetic sample collection. Whereas factors positively associated with receptivity to research participation were "complete trust" in health-care providers (OR, 2.091; 95% CI, 1.544-2.833), upper income strata (OR, 2.319; 95% CI, 1.308-4.114), viewing genetic research "very positively" (OR, 3.524; 95% CI, 2.122-5.852), and expressing "no worry at all" regarding disclosure of results (OR, 2.505; 95% CI, 1.436-4.369), black race was negatively associated with research participation (OR, 0.410; 95% CI, 0.288-0.585). We could detect no difference in receptivity to genetic sample collection comparing ambulatory patients and surrogates (OR, 0.738; 95% CI, 0.511-1.066). Expressing trust in health-care providers and viewing genetic research favorably were associated with increased willingness for study enrollment, while concern regarding breach of confidentiality and black race had the opposite effect. Study setting had no bearing on willingness to participate.

The relation between receptive grammar and procedural, declarative, and working memory in specific language impairment.

What memory systems underlie grammar in children, and do these differ between typically developing (TD) children and children with specific language impairment (SLI)? Whilst there is substantial evidence linking certain memory deficits to the language problems in children with SLI, few studies have investigated multiple memory systems simultaneously, examining not only possible memory deficits but also memory abilities that may play a compensatory role. This study examined the extent to which procedural, declarative, and working memory abilities predict receptive grammar in 45 primary school aged children with SLI (30 males, 15 females) and 46 TD children (30 males, 16 females), both on average 9;10 years of age. Regression analyses probed measures of all three memory systems simultaneously as potential predictors of receptive grammar. The model was significant, explaining 51.6% of the variance. There was a significant main effect of learning in procedural memory and a significant group × procedural learning interaction. Further investigation of the interaction revealed that procedural learning predicted grammar in TD but not in children with SLI. Indeed, procedural learning was the only predictor of grammar in TD. In contrast, only learning in declarative memory significantly predicted grammar in SLI. Thus, different memory systems are associated with receptive grammar abilities in children with SLI and their TD peers. This study is, to our knowledge, the first to demonstrate a significant group by memory system interaction in predicting grammar in children with SLI and their TD peers. In line with Ullman's Declarative/Procedural model of language and procedural deficit hypothesis of SLI, variability in understanding sentences of varying grammatical complexity appears to be associated with variability in procedural memory abilities in TD children, but with declarative memory, as an apparent compensatory mechanism, in children with SLI.

To compare the performance in the abilities of receptive and expressive language of children with cleft lip and palate with that of children without cleft lip and palate with typical 12 to 36-month chronological development. The sample consisted of 60 children aged 12 and 36 months: 30 with cleft lip and palate diagnosis and 30 without cleft lip and palate diagnosis with typical development. The groups were paired according to gender, age (in months), and socioeconomic level. The procedures consisted of analysis of medical records, anamnesis with family members, and valuation of the Early Language Milestone Scale (ELMS). The chart analysis showed 63.34% of the children with unilateral cleft lip and palate, 16.66% with bilateral incisive transforamen cleft, and 20% with post-foramen cleft. Children with cleft lip and palate underwent surgeries (lip repair and/or palatoplasty) at the recommended ages and participated in early intervention programs; 40% presented recurrent otitis history, and 50% attended schools. Statistical analysis included the use of the Mann Whitney test with significance level of p cleft lip and palate showed statistically significant low performance in receptive and expressive language compared with children without cleft lip and palate.

It is unclear what the predictive value of very early development of gestures and language is on later language ability in prematurely born very-low-birth-weight (VLBW; birth weight ≤1500g) children. The aim of the present study was to analyse the predictive value of early gestures and a receptive lexicon measured between the ages of 0;9 and 1;3, as well as the predictive value of receptive and expressive language ability at 2;0 for language skills at 5;0 in VLBW children. The subjects were 29 VLBW children and 28 full-term children whose language development has been followed intensively between the ages of 0;9 and 2;0 using the Finnish version of the MacArthur Developmental Inventory and the Reynell Developmental Language Scales (RDLS III). At 5;0, five selected verbal subtests of the Nepsy II test and the Boston Naming Test (BNT) were used to assess children's language skills. For the first time in VLBW children, the development of gestures measured between the ages of 0;9 and 1;3 was shown to correlate significantly and positively with language skills at 5;0. In addition, both receptive and expressive language ability measured at 2;0 correlated significantly and positively with later language skills in both groups. Moreover, according to the hierarchical regression analysis, the receptive language score of the RDLS III at 2;0 was a clear and significant predictor for language skills at 5;0 in both groups. The findings particularly underline the role of early receptive language as a significant predictor for later language ability in VLBW children. The results provide evidence for a continuity between early language development and later language skills. After reading this article, readers will understand the associations between the very early (≤2 years of age) development of gestures and language (i.e. early receptive lexicon, expressive lexicon at 2;0, receptive and expressive language ability at 2;0) and the language skills at 5;0 in prematurely born

Peripheral auditory processing and speech reception in impaired hearing

DEFF Research Database (Denmark)

Strelcyk, Olaf

One of the most common complaints of people with impaired hearing concerns their difficulty with understanding speech. Particularly in the presence of background noise, hearing-impaired people often encounter great difficulties with speech communication. In most cases, the problem persists even...... if reduced audibility has been compensated for by hearing aids. It has been hypothesized that part of the difficulty arises from changes in the perception of sounds that are well above hearing threshold, such as reduced frequency selectivity and deficits in the processing of temporal fine structure (TFS......) at the output of the inner-ear (cochlear) filters. The purpose of this work was to investigate these aspects in detail. One chapter studies relations between frequency selectivity, TFS processing, and speech reception in listeners with normal and impaired hearing, using behavioral listening experiments. While...

Despite their genetic similarity to humans, our understanding of the role of genes on cognitive traits in chimpanzees remains virtually unexplored. Here, we examined the relationship between genetic variation in the arginine vasopressin V1a receptor gene (AVPR1A) and social cognition in chimpanzees...... cognition task was significantly heritable. Furthermore, males with one DupB(+) allele performed significantly better and were more responsive to socio-communicative cues than males homozygous for the DupB- deletion. Performance on a non-social cognition task was not associated with the AVPR1A genotype....... The collective findings show that AVPR1A polymorphisms are associated with individual differences in performance on a receptive joint attention task in chimpanzees....

As countries prohibit tobacco marketing through traditional channels, marketing at point of sale (PoS) and through tobacco packaging is increasingly important for promoting tobacco consumption. Assess the validity of a novel marketing receptivity index that considers frequency of PoS exposures, tobacco brand recall and ownership of branded merchandise. Data come from a cross-sectional survey of 3172 secondary school students in Argentina. Questions assessed frequency of going to stores where tobacco is often sold; cued recall of brand names for 3 cigarette packages with brand name removed and ownership of branded merchandise. A four-level marketing receptivity index was derived: low PoS exposure only; high PoS exposure or recall of 1 brand; recall of 2 or more brands; and ownership of branded merchandise. Indicators of marketing receptivity and smoking involvement were regressed on the index, including in adjusted models that controlled for sociodemographics, social influences and sensation seeking. Among never-smokers, the index had independent positive associations with smoking susceptibility (ie, adjusted OR (AOR) 2v1 =1.66; AOR 3v1 =1.64; AOR 4v1 =2.95), willingness to try a specific brand (ie, AOR 2v1 =1.45; AOR 3v1 =2.38; AOR 4v1 =2.20) and positive smoking expectancies (ie, B adj 2v1 =0.09; B adj 3v1 =0.18; B adj 4v1 =0.34). A more marked dose-response independent association was found with current smoking behaviour (ie, AOR 2v1 =2.47; AOR 3v1 =3.16; AOR 4v1 =3.62). The marketing receptivity index was associated with important variation in smoking-related perceptions, intentions and behaviour among Argentine adolescents. Future research should determine the predictive validity and generalisability of this measure to other contexts, including the explanatory power gained by integrating cigarette package brand recognition tasks.

We investigated the relationship between receptivity to electronic cigarette (e-cigarette) advertisements at baseline and e-cigarette use at follow-up among adult baseline non-users of cigarettes and e-cigarettes. A nationally representative online panel was used to survey non-users of cigarettes and e-cigarettes ( n  = 2191) at baseline and 5-month follow-up. At baseline, respondents were shown an e-cigarette advertisement and asked if they were aware of it (exposure). Among those exposed, receptivity was self-rated for each ad using a validated scale of 1 to 5 for agreement with each of six items: "worth remembering," "grabbed my attention," "powerful," "informative," "meaningful," and "convincing." Logistic regression was used to measure the relationship between receptivity at baseline and e-cigarette use at follow-up. Among baseline non-users of cigarettes and e-cigarettes, 16.6% reported exposure to e-cigarette advertisements at baseline; overall mean receptivity score was 2.77. Among baseline non-users who reported exposure to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 2.7%; among baseline non-users who reported not being exposed to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 1.3%. The attributable risk percentage for e-cigarette initiation from e-cigarette advertisement exposure was 59.3%; the population attributable risk percentage from e-cigarette advertisement exposure was 22.6%. Receptivity at baseline was associated with e-cigarette use at follow-up (aOR = 1.57; 95% CI = 1.04-2.37). Receptivity to e-cigarette advertisements at baseline was associated with greater odds of e-cigarette use at follow-up among baseline non-users of cigarettes and e-cigarettes. Understanding the role of advertising in e-cigarette initiation could help inform public health policy.

Language profiles of children with autistic disorder and intellectual disability (n = 36) were significantly different from the comparison groups of children with intellectual disability (n = 26) and typically developing children (n = 34). The group low-functioning children with autistic disorder obtained a higher mean score on expressive than on receptive language, whereas both comparison groups showed the reverse pattern. Nonverbal mental age, joint attention, and symbolic understanding of pictures were analyzed in relation to concurrent receptive and expressive language abilities. In the group with autistic disorder and intellectual disability, symbol understanding and joint attention were most strongly related to language abilities. Nonverbal mental age was the most important predictor of language abilities in the comparison groups.

The publication of Newton's Opera Omnia in Geneva and Lausanne (1739-1761): A chapter in the reception of Newtonianism.

Guicciardini, Niccolò

2017-12-01

During the eighteenth century, several towns located in what is known today as the Suisse romande were extremely receptive toward scientific culture, and most notably Newtonianism. In this paper I deal with a nine-volume publication of Newton's Opera Omnia that was planned in Geneva and Lausanne during the late 1730s and 1740s. This publication has not received the attention it deserves. To the best of my knowledge, even an awareness of its existence is lacking in the literature devoted to the reception of Newtonianism. This paper examines the circumstances of the publication of a complete set of all of Newton's works known at the time, and the motivations of the editors, mathematicians, and publishers who were involved in this editorial enterprise.

Goldberg, Jay K.; Wallace, Alisa K.; Weiss, Stacey L.

2017-10-01

Sex pheromones can perform a variety of functions ranging from revealing the location of suitable mates to being honest signals of mate quality, and they are used in the mate selection process by many species of reptile. In this study, we determined whether the skin lipids of female striped plateau lizards ( Sceloporus virgatus) can predict the reproductive quality of females, thereby having the potential to serve as pheromones. Using gas chromatography/mass spectrometry, we identified 17 compounds present in skin lipids of female lizards. Using principal component analysis to compare the skin lipid profile of receptive and non-receptive females, we determined that an uncharacterized compound may allow for chemical identification of receptive mates. We also compared extracted principal components to measures of female fitness and reproductive qualities and found that the level of two 18 carbon fatty acids present in a female's skin lipids may indicate her clutch size. Finally, we compared the information content of the skin lipids to that of female-specific color ornaments to assess whether chemical and visual cues transmit different information or not. We found that the chroma of a female's orange throat patch is also related to her clutch size, suggesting that chemical signals may reinforce the information communicated by visual ornamentation in this species which would support the "backup signals" hypothesis for multiple signals.

2013-01-01

This study aimed to compare imitation skills in children with autism spectrum disorder, and age-matched typically developing children and children with developmental delay, as well as to examine the association between imitation skills, and receptive and expressive language development in children with autism spectrum disorder. Imitation skills in children with autism spectrum disorder (n=18), and age-matched children with developmental delay (n=15) and typically developing children (n= 16) were assessed using the Motor Imitation Scale and Imitation Battery, and the differences in mean imitation scores between the groups were examined. Receptive language and expressive language development in the children with autism spectrum disorder were assessed using the Turkish Communicative Development Inventory (TCDI), and their association with imitation scores was explored. The children with autism spectrum disorder had significantly lower imitation scores than the children with developmental delay and typically developing children; however, there wasn't a significant difference in imitation scores between the children with developmental delay and typically developing children. A significant association between imitation scores, and receptive and expressive language development was observed in the children with autism spectrum disorder. The present findings indicate that deficient imitation skills are a distinctive feature of children with autism spectrum disorder and that imitation skills play a crucial role in children's language development.

Effects of Forward- and Backward-Facing Steps on the Crossflow Receptivity and Stability in Supersonic Boundary Layers

Balakumar, P.; King, Rudolph A.; Eppink, Jenna L.

2014-01-01

The effects of forward- and backward-facing steps on the receptivity and stability of three-dimensional supersonic boundary layers over a swept wing with a blunt leading edge are numerically investigated for a freestream Mach number of 3 and a sweep angle of 30 degrees. The flow fields are obtained by solving the full Navier-Stokes equations. The evolution of instability waves generated by surface roughness is simulated with and without the forward- and backward-facing steps. The separation bubble lengths are about 5-10 step heights for the forward-facing step and are about 10 for the backward-facing step. The linear stability calculations show very strong instability in the separated region with a large frequency domain. The simulation results show that the presence of backward-facing steps decreases the amplitude of the stationary crossflow vortices with longer spanwise wavelengths by about fifty percent and the presence of forward-facing steps does not modify the amplitudes noticeably across the steps. The waves with the shorter wavelengths grow substantially downstream of the step in agreement with the linear stability prediction.

The aim of the present work was to optimize the signal to noise ratio in our NMR imaging system (TORM 005) by improving transducer`s reception quality through better designed coils, balanced tuning circuit for this coils and power decoupling circuits and by reducing interference from the electromagnetic environment. For this purpose, we had to modify the internal electromagnetic shielding and incorporate line filters in the more critical signals paths. Also, new types of coils were developed, improving the signal to noise ratio, and allowing us to make clinical exams with superior quality for several anatomies. Balanced circuits for tuning and matching of the coil were studied and built, allowing a reduction of the coil losses because patient`s load. This produced a more reliable coil tuning after positioning each new patient. Circuits to avoid the receiver input overload and decoupling circuits for the isolation of receiver coils from excitation coil were designed and incorporated to the TORM 005. All these alterations of our imaging system (TORM 005) contributed to a significant improvement in the signal to noise ratio, reliability and reproducibility of the system. This permitted to operate the system routinely for clinical applications, research and development in the area of ultra low magnetic field tomography. (author) 46 refs., 66 figs., 11 tabs.

Reception of nuclear medicine department is often ignored. In fact, it is an important part of clinical work. If the patient's psychological status is understood, and the psychological knowledge is handles and applied in practice, the quality of work can be improved. The personnel in nuclear medicine should recognize the significance of humanity in medical practice and acquire the communication skill between doctors and patients. They should also understand the four aspects of psychological need of patients: The need of being understood and respected; the need of being greeted, accepted and a sense of belonging; the need of being informed; the need of feeling safe and rehabilitated

Neonatal DHT but not E2 speeds induction of sexual receptivity in the musk shrew.

Ewton, Tiffany A; Siboni, Ruth B; Jackson, Andrea; Freeman, Louise M

2010-06-01

Neural aromatization of testosterone (T) to estrogen during development is thought to be important for sexual differentiation of many altricial mammals. We evaluated the effects of neonatal injections of the non-aromatizable androgen dihydrotestosterone propionate (DHTP) and estradiol (E2) on the copulatory behavior of the female musk shrew, an altricial insectivore. Following adult ovariectomy and replacement T, animals were paired with a stimulus female for two 60-minute copulatory behavior tests. The latency to induce sexual receptivity (in the form of tail-wagging by the female), mount latency and total number of mounts were recorded in experimental females and in a group of untreated control males. While neither hormone treatment significantly affected mounting behavior, DHTP-treated animals induced receptivity faster and with latencies not significantly different from intact males, suggesting that early non-aromatizable androgens can have masculinizing actions by either increasing sexual motivation or making the treated animal more attractive to the stimulus female. Reliance on androgenic rather than estrogenic metabolites for the differentiation of courtship behaviors conforms to the pattern seen more typically in primates than rodents.

Receptive females mitigate costs of sexual conflict.

Science.gov (United States)

Harano, T

2015-02-01

Males typically gain fitness from multiple mating, whereas females often lose fitness from numerous mating, potentially leading to sexual conflict over mating. This conflict is expected to favour the evolution of female resistance to mating. However, females may incur male harassment if they refuse to copulate; thus, greater female resistance may increase costs imposed by males. Here, I show that the evolution of resistance to mating raises fitness disadvantages of interacting with males when mating is harmful in female adzuki bean beetles, Callosobruchus chinensis. Females that were artificially selected for higher and lower remating propensity evolved to accept and resist remating, respectively. Compared with females that evolved to accept remating, females that evolved to resist it suffered higher fitness costs from continuous exposure to males. The costs of a single mating measured by the effect on longevity did not differ among selection line females. This study indicates that receptive rather than resistant females mitigate the fitness loss resulting from sexual conflict, suggesting that even though mating is harmful, females can evolve to accept additional mating. © 2014 European Society For Evolutionary Biology.

An enstrophy-based linear and nonlinear receptivity theory

Science.gov (United States)

Sengupta, Aditi; Suman, V. K.; Sengupta, Tapan K.; Bhaumik, Swagata

2018-05-01

In the present research, a new theory of instability based on enstrophy is presented for incompressible flows. Explaining instability through enstrophy is counter-intuitive, as it has been usually associated with dissipation for the Navier-Stokes equation (NSE). This developed theory is valid for both linear and nonlinear stages of disturbance growth. A previously developed nonlinear theory of incompressible flow instability based on total mechanical energy described in the work of Sengupta et al. ["Vortex-induced instability of an incompressible wall-bounded shear layer," J. Fluid Mech. 493, 277-286 (2003)] is used to compare with the present enstrophy based theory. The developed equations for disturbance enstrophy and disturbance mechanical energy are derived from NSE without any simplifying assumptions, as compared to other classical linear/nonlinear theories. The theory is tested for bypass transition caused by free stream convecting vortex over a zero pressure gradient boundary layer. We explain the creation of smaller scales in the flow by a cascade of enstrophy, which creates rotationality, in general inhomogeneous flows. Linear and nonlinear versions of the theory help explain the vortex-induced instability problem under consideration.

A comparison of methods for teaching receptive language to toddlers with autism.

The use of a simple-conditional discrimination training procedure, in which stimuli are initially taught in isolation with no other comparison stimuli, is common in early intensive behavioral intervention programs. Researchers have suggested that this procedure may encourage the development of faulty stimulus control during training. The current study replicated previous work that compared the simple-conditional and the conditional-only methods to teach receptive labeling of pictures to young children with autism spectrum disorder. Both methods were effective, but the conditional-only method required fewer sessions to mastery. © Society for the Experimental Analysis of Behavior.

A cavitation model based on Eulerian stochastic fields

Science.gov (United States)

Magagnato, F.; Dumond, J.

2013-12-01

Non-linear phenomena can often be described using probability density functions (pdf) and pdf transport models. Traditionally the simulation of pdf transport requires Monte-Carlo codes based on Lagrangian "particles" or prescribed pdf assumptions including binning techniques. Recently, in the field of combustion, a novel formulation called the stochastic-field method solving pdf transport based on Eulerian fields has been proposed which eliminates the necessity to mix Eulerian and Lagrangian techniques or prescribed pdf assumptions. In the present work, for the first time the stochastic-field method is applied to multi-phase flow and in particular to cavitating flow. To validate the proposed stochastic-field cavitation model, two applications are considered. Firstly, sheet cavitation is simulated in a Venturi-type nozzle. The second application is an innovative fluidic diode which exhibits coolant flashing. Agreement with experimental results is obtained for both applications with a fixed set of model constants. The stochastic-field cavitation model captures the wide range of pdf shapes present at different locations.

Full Text Available The aim of this paper is to analyze the reception of Machiavelli and the neo machiavellian (Pareto, Mosca, Michels, in the main Political Science paradigms, as well as in the teaching of this discipline at the University of the Republic, from 1957, when the first Political Science chair was created at the Law School, till 1985, when Uruguay returned to democracy, after a twelve-year period of civil-military dictatorship. For this purpose, first, this article will review the itinerary of international Political Science, presenting the different stages that this discipline has gone through. Then, it will make an approach to the reception of Machiavelli and the neo-machiavellian in three political scientists of great significance: Harold Laswell, Robert Dahl and Giovanni Sartori. Second, the paper will examine the reception of the works of the Florentine author and the elitist theorists in three Political Science chairs that were conducted during the indicated period by Alberto Ramón Real, Carlos Real de Azúa and Jacques Ginesta. Finally, there will be a reflection on the different emphases that were made in the teaching of Political Science at that time, particularly following the intervention of the University after the 1973 coup d’État.

Full Text Available In this article, we studied student dissertations in cultural studies departments and articles of two important journals (Iranian Journal of Cultural Research and Quarterly Journal of Iranian Association for Cultural Studies & Communication. Our main questions are how the condition of reception possibility is assumed in Iranian cultural studies? How we can classify our audiences? In particular, how and who is the audience in Iran? This analysis shows that most of the Iranian cultural studies oriented to urban middle class of Tehran, instead of lower middle class or labor class. The result demonstrates that, most of scholars consider audience as an active subject that resists against text massages. Hence, they overlook the role of ideology and power in construction of subject and audience. As if, a type of optimistic cultural studies was adapted in an authoritarian political context. This approach on resistance is called resistance ideology by the authors; a situation in which we believe resistance is a sort of relieving and appeasing drug for critical cultural scholars.

While covering all commentaries, our response specifically focuses on the following issues: How can the hypothesis of emotional distancing (qua art framing) be compatible with stipulating high levels of felt negative emotions in art reception? Which concept of altogether pleasurable mixed emotions does our model involve? Can mechanisms of predictive coding, social sharing, and immersion enhance the power of our model?

Interaction between the soma and the axon terminal of horizontal cells in carp retina

In teleost retina, the receptive fields of horizontal cell axon terminals have a larger space constant than the receptive fields of the horizontal cell somata. Generally this difference in receptive field size is attributed to the cell coupling which is assumed to be stronger in the horizontal axon

Denying Difference to the Post-Socialist Other: Bernhard Heisig and the Changing Reception of an East German Artist

Directory of Open Access Journals (Sweden)

April A. Eisman

2012-04-01

Full Text Available This article traces the reception of East German artist Bernhard Heisig’s life and art—first in East Germany and then in the Federal Republic of Germany before and after the Wall. Drawing on post-colonial and post-socialist scholarship, it argues that Heisig’s reception exemplifies a western tendency to deny cultural and ideological difference in what the post-socialist scholar Piotr Piotrowski calls the “close Other.” This denial of difference to artists from the eastern bloc has shaped western understandings of Heisig’s life and art since reunification. Once perceived as an intellectually engaged, political artist, both in East and West Germany, after the fall of the Wall and German unification, Heisig was reinterpreted as a traumatized victim of two dictatorships, distorting not only our understanding of the artist and his work, but also of the nature of art and the role of the artist in East Germany.

Non-native scientists, research dissemination and English neologisms: What happens in the early stages of reception and re-production?

Directory of Open Access Journals (Sweden)

Daniel Linder

2016-11-01

Full Text Available That the English language is the prevailing language in international scientific discourse is an undeniable fact for research professionals who are non-native speakers of English (NNSE. An exploratory, survey-based study of scientists in the experimental disciplines of neuroscience and medicine seeks to reveal, on the one hand, the habits of scientists who in their research practice come across neologisms in English and need to use them in oral and written scientific discourse in their own languages, and, on the other hand, their attitudes towards these neologisms and towards English as the language of international science. We found that all scientists write and publish their research articles (RAs in English and most submit them unrevised by native speakers of English. When first encountering a neologism in English, scientists tend to pay close attention to these new concepts, ideas or terms and very early in the reception process attempt to coin acceptable, natural-sounding Spanish equivalents for use in the laboratory and in their Spanish texts. In conjunction with the naturalized Spanish term, they often use the English neologism verbatim in a coexistent bilingual form, but they avoid using only the English term and very literal translations. These behaviors show an ambivalent attitude towards English (the language of both new knowledge reception and dissemination of their RAs and Spanish (used for local professional purposes and for popularization: while accepting to write in their acquired non-native language, they simultaneously recognize that their native language needs to preserve its specificity as a language of science.

Receptivity of Boundary Layer over a Blunt Wedge due to Freestream Pulse Disturbances at Mach 6

Directory of Open Access Journals (Sweden)

Jianqiang Shi

2016-01-01

Full Text Available Direct numerical simulation (DNS of a hypersonic compressible flow over a blunt wedge with fast acoustic disturbances in freestream is performed. The receptivity characteristics of boundary layer to freestream pulse acoustic disturbances are numerically investigated at Mach 6, and the frequency effects of freestream pulse wave on boundary layer receptivity are discussed. Results show that there are several main disturbance mode clusters in boundary layer under acoustic pulse wave, and the number of main disturbance clusters decreases along the streamwise. As disturbance wave propagates from upstream to downstream direction, the component of the modes below fundamental frequency decreases, and the component of the modes above second harmonic components increases quickly in general. There are competition and disturbance energy transfer between different boundary layer modes. The nose boundary layer is dominated by the nearby mode of fundamental frequency. The number of the main disturbance mode clusters decreases as the freestream disturbance frequency increases. The frequency range with larger growth narrows along the streamwise. In general, the amplitudes of both fundamental mode and harmonics become larger with the decreasing of freestream disturbance frequency. High frequency freestream disturbance accelerates the decay of disturbance wave in downstream boundary layer.

Everyday Citizenship: Identity Claims and Their Reception

Directory of Open Access Journals (Sweden)

Nick Hopkins

2015-10-01

Full Text Available Citizenship involves being able to speak and be heard as a member of the community. This can be a formal right (e.g., a right to vote. It can also be something experienced in everyday life. However, the criteria for being judged a fellow member of the community are multiple and accorded different weights by different people. Thus, although one may self-define alongside one’s fellows, the degree to which these others reciprocate depends on the weight they give to various membership criteria. This suggests we approach everyday community membership in terms of an identity claims-making process in which first, an individual claims membership through invoking certain criteria of belonging, and second, others evaluate that claim. Pursuing this logic we report three experiments investigating the reception of such identity-claims. Study 1 showed that in Scotland a claim to membership of the national ingroup was accepted more if couched in terms of place of birth and ancestry rather than just in terms of one’s subjective identification. Studies 2 and 3 showed that this differential acceptance mattered for the claimant’s ability to be heard as a community member. We discuss the implications of these studies for the conceptualization of community membership and the realization of everyday citizenship rights.

DNS and the theory of receptivity of a supersonic boundary layer to free-stream disturbances

International Nuclear Information System (INIS)

Soudakov, Vitaly; Fedorov, Alexander; Ryzhov, Alexander

2011-01-01

Direct numerical simulation (DNS) of receptivity of a boundary layer over flat plate is carried out. The free stream Mach number is equal to 6. The following two-dimensional disturbances are introduced into the free-stream flow: fast and slow acoustic waves, temperature spottiness. A theoretical model describing the excitation of unstable waves in the boundary layer is developed using the biorthogonal eigenfunction decomposition method. The DNS results agree with the theoretical predictions.

Application of biorthogonal eigenfunction system for extraction of Tollmien-Schlichting waves in acoustic receptivity simulations

Acoustic receptivity of a two-dimensional boundary layer on a flat plate with elliptic leading edge is studied through direct numerical simulation (DNS). Sound waves are modelled by a uniform oscillation of freestream boundaries in time which results to an infinite-wavelength acoustic wave. Acoustic disturbances interact with strong streamwise gradients at the leading edge or surface non- homogeneities and create Tollmien-Schlichting (TS) waves inside the boundary layer.

Emergent spatial patterns of excitatory and inhibitory synaptic strengths drive somatotopic representational discontinuities and their plasticity in a computational model of primary sensory cortical area 3b

Directory of Open Access Journals (Sweden)

Kamil A. Grajski

2016-07-01

Full Text Available Mechanisms underlying the emergence and plasticity of representational discontinuities in the mammalian primary somatosensory cortical representation of the hand are investigated in a computational model. The model consists of an input lattice organized as a three-digit hand forward-connected to a lattice of cortical columns each of which contains a paired excitatory and inhibitory cell. Excitatory and inhibitory synaptic plasticity of feedforward and lateral connection weights is implemented as a simple covariance rule and competitive normalization. Receptive field properties are computed independently for excitatory and inhibitory cells and compared within and across columns. Within digit representational zones intracolumnar excitatory and inhibitory receptive field extents are concentric, single-digit, small, and unimodal. Exclusively in representational boundary-adjacent zones, intracolumnar excitatory and inhibitory receptive field properties diverge: excitatory cell receptive fields are single-digit, small, and unimodal; and the paired inhibitory cell receptive fields are bimodal, double-digit, and large. In simulated syndactyly (webbed fingers, boundary-adjacent intracolumnar receptive field properties reorganize to within-representation type; divergent properties are reacquired following syndactyly release. This study generates testable hypotheses for assessment of cortical laminar-dependent receptive field properties and plasticity within and between cortical representational zones. For computational studies, present results suggest that concurrent excitatory and inhibitory plasticity may underlie novel emergent properties.

The Comparative Effects of Comprehensible Input, Output and Corrective Feedback on the Receptive Acquisition of L2 Vocabulary Items

Full Text Available In the present study, the comparative effects of comprehensible input, output and corrective feedback on the receptive acquisition of L2 vocabulary items were investigated. Two groups of beginning EFL learners participated in the study. The control group received comprehensible input only, while the experimental group received input and was required to produce written output. They also received corrective feedback on their lexical errors if any. This could result in the production of modified output. The results of the study indicated that (a the group which produced output and received feedback (if necessary outperformed the group which only received input in the post-test, (b within the experimental group, feedback played a greater role in learners’ better performance than output, (c also a positive correlation between the amount of feedback an individual learner received, and his overall performance in the post-test; and also between the amount of feedback given for a specific word and the correct responses given to its related item in the post-test was found.  The findings of this study provide evidence for the role of output production along with receiving corrective feedback in enhancing L2 processing by drawing further L2 learners’ attention to their output which in turn may result in improving their receptive acquisition of L2 words. Furthermore, as the results suggested, feedback made a more contribution to L2 development than output. Keywords: comprehensible input, output, interaction, corrective feedback, modified output, receptive vocabulary acquisition

Bion's Notes on memory and desire--its initial clinical reception in the United States: a note on archival material.

Science.gov (United States)

Aguayo, Joseph

2014-10-01

While Bion's 1967 memory and desire paper reflected a crucial episode in his clinical thinking during his epistemological period, it was also central to his evolution as a Kleinian psychoanalyst who worked with seriously disturbed adult patients. The author explicates and contextualizes these claims with a new archival document, the Los Angeles Seminars delivered by Bion in April 1967, and the full-length version of Notes on memory and desire. Bion here instigated a radical departure from years of theory-laden work when he made his clinical work and ideas accessible to a new audience of American Freudian analysts. While this new group was keenly interested to hear about Bion's clinical technique with both borderline and psychotic patients, there were varied reactions to Bion's ideas on the technical implications of the analyst's abandonment of memory and desire. Both the Los Angeles Seminars and Notes elicited responses ranging from bewilderment, admiration to skepticism amongst his audience of listeners and readers. These materials also however allow for a more complete and systematic presentation of important ideas about analytic technique - and while his ideas in this domain have been long valued and known by many psychoanalysts, this contribution stresses the crucial aspect of the reception of his ideas about technique in a particular American context. American analysts gained a much more explicit idea of how Bion worked analytically, how he listened, formulated interpretations and factored in the analyst's listening receptivity in the here-and-now. The author concludes with a consideration of the importance of Bion's American reception in 1967. Copyright © 2014 Institute of Psychoanalysis.

Full Text Available ABSTRACT Objective: To investigate reception of nutrition information (outcome, associated factors, and types of sources. Methods: This cross-sectional study, conducted in 2013, included 1,246 adult and older adult users of the Primary Healthcare network of Pelotas, Rio Grande do Sul, Brazil. The sample was characterized by reception of nutrition information, its sources, and demographic, socioeconomic, health, knowledge, and life habit variables. Prevalence ratios and their respective 95% confidence intervals investigated associations between reception of nutrition information and independent variables. Results: More than one-third of the sample (37.6% received nutrition information (95%CI=34.9-40.3. Older adults, individuals with positive self-perceived diet, those who received health information, and those who were physically active were more likely to receive nutrition information, and normal weight individuals were less likely. The outcome differed by income strata, being highest in the highest quintile. There was a linear trend for education level and for following the Ten Steps to Healthy Eating: the outcome was more likely in individuals with at least higher education and those who followed at least four steps. The most cited sources of nutrition information were television shows (56.2%, other (46.2%, physician (41.2%, Internet (25.1%, and family members (20.9%, which did not differ by sex. Conclusion: Primary healthcare users received little nutrition information, and television could be a useful tool for the institutions responsible for the sector to disseminate the official nutritional recommendations.

Improved nowcasting of precipitation based on convective analysis fields

Full Text Available The high-resolution analysis and nowcasting system INCA (Integrated Nowcasting through Comprehensive Analysis developed at the Austrian national weather service provides three-dimensional fields of temperature, humidity, and wind on an hourly basis, and two-dimensional fields of precipitation rate in 15 min intervals. The system operates on a horizontal resolution of 1 km and a vertical resolution of 100–200 m. It combines surface station data, remote sensing data (radar, satellite, forecast fields of the numerical weather prediction model ALADIN, and high-resolution topographic data. An important application of the INCA system is nowcasting of convective precipitation. Based on fine-scale temperature, humidity, and wind analyses a number of convective analysis fields are routinely generated. These fields include convective boundary layer (CBL flow convergence and specific humidity, lifted condensation level (LCL, convective available potential energy (CAPE, convective inhibition (CIN, and various convective stability indices. Based on the verification of areal precipitation nowcasts it is shown that the pure translational forecast of convective cells can be improved by using a decision algorithm which is based on a subset of the above fields, combined with satellite products.

The Distancing-Embracing model of the enjoyment of negative emotions in art reception.

Menninghaus, Winfried; Wagner, Valentin; Hanich, Julian; Wassiliwizky, Eugen; Jacobsen, Thomas; Koelsch, Stefan

2017-01-01

Why are negative emotions so central in art reception far beyond tragedy? Revisiting classical aesthetics in the light of recent psychological research, we present a novel model to explain this much discussed (apparent) paradox. We argue that negative emotions are an important resource for the arts in general, rather than a special license for exceptional art forms only. The underlying rationale is that negative emotions have been shown to be particularly powerful in securing attention, intense emotional involvement, and high memorability, and hence is precisely what artworks strive for. Two groups of processing mechanisms are identified that conjointly adopt the particular powers of negative emotions for art's purposes. The first group consists of psychological distancing mechanisms that are activated along with the cognitive schemata of art, representation, and fiction. These schemata imply personal safety and control over continuing or discontinuing exposure to artworks, thereby preventing negative emotions from becoming outright incompatible with expectations of enjoyment. This distancing sets the stage for a second group of processing components that allow art recipients to positively embrace the experiencing of negative emotions, thereby rendering art reception more intense, more interesting, more emotionally moving, more profound, and occasionally even more beautiful. These components include compositional interplays of positive and negative emotions, the effects of aesthetic virtues of using the media of (re)presentation (musical sound, words/language, color, shapes) on emotion perception, and meaning-making efforts. Moreover, our Distancing-Embracing model proposes that concomitant mixed emotions often help integrate negative emotions into altogether pleasurable trajectories.

1995-01-01

Low intensity millimeter-wave electromagnetic radiation of less than 10 mW cm -2 power intensity has a nonthermal effect on the body and it is widely used in medical practice for treatment of various diseases. Nevertheless, the effect of EMR on biological tissues is not understood. The skin and its sensory receptors are considered to be responsible for EMR reception, but this has yet to be confirmed. The present experiments were designed to study the effect of millimeter-wave electromagnetic radiation on the ampullae of Lorenzini in skates, which are very sensitive to weak electrical stimuli at low frequency.

Ontologies are widely used both in the life sciences and in the management of public and private companies. Typically, the different offices in an organization develop their own models and related ontologies to capture specific tasks and goals. Although there might be an overall coordination, the use of distinct ontologies can jeopardize the integration of data across the organization since data sharing and reusability are sensitive to modeling choices. The paper provides a study of the entities that are typically found at the reception, analysis and report phases in public institutes in the life science domain. Ontological considerations and techniques are introduced and their implementation exemplified by studying the Istituto Zooprofilattico Sperimentale delle Venezie (IZSVe), a public veterinarian institute with different geographical locations and several laboratories. Different modeling issues are discussed like the identification and characterization of the main entities in these phases; the classification of the (types of) data; the clarification of the contexts and the roles of the involved entities. The study is based on a foundational ontology and shows how it can be extended to a comprehensive and coherent framework comprising the different institute's roles, processes and data. In particular, it shows how to use notions lying at the borderline between ontology and applications, like that of knowledge object. The paper aims to help the modeler to understand the core viewpoint of the organization and to improve data transparency. The study shows that the entities at play can be analyzed within a single ontological perspective allowing us to isolate a single ontological framework for the whole organization. This facilitates the development of coherent representations of the entities and related data, and fosters the use of integrated software for data management and reasoning across the company.

The majority of a child's language development occurs in the first 5 years of life when brain development is most rapid. There are significant long-term benefits to supporting all children's language and literacy development such as maximizing their developmental potential (i.e., cognitive, linguistic, social-emotional), when children are experiencing a critical period of development (i.e., early childhood to 9 years of age). A variety of people play a significant role in supporting children's language development, including parents, guardians, family members, educators, and/or speech-language pathologists. Speech-language pathologists and educators are the professionals who predominantly support children's language development in order for them to become effective communicators and lay the foundation for later developing literacy skills (i.e., reading and writing skills). Therefore, these professionals need formal and informal assessments that provide them information on a child's understanding and/or use of the increasingly complex aspects of language in order to identify and support the receptive and expressive language learning needs of diverse children during their early learning experiences (i.e., aged 1.5 to 9 years). However, evidence on what methods and tools are being used is lacking. The authors will carry out a scoping review of the literature to identify studies and map the receptive and expressive English language assessment methods and tools that have been published and used since 1980. Arksey and O'Malley's (2005) six-stage approach to conducting a scoping review was drawn upon to design the protocol for this investigation: (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; (5) collating, summarizing, and reporting the results; and (6) consultation. This information will help these professionals identify and select appropriate assessment methods or tools that can be used to support

The re-establishment of malaria has become an important public health issue in and out of China, and receptivity to this disease is key to its re-emergence. Yingjiang is one of the few counties with locally acquired malaria cases in the China-Myanmar border in China. This study aimed to understand receptivity to malaria in Yingjiang County, China, from June to October 2016. Light-traps were employed to capture the mosquitoes in 17 villages in eight towns which were categorized into four elevation levels: level 1, 0-599 m; level 2, 600-1199 m; level 3, 1200-1799 m; and level 4, > 1800 m. Species richness, diversity, dominance and evenness were used to picture the community structure. Similarity in species composition was compared between different elevation levels. Data of seasonal abundance of mosquitoes, human biting rate, density of light-trap-captured adult mosquitoes and larvae, parous rate, and height distribution (density) of Anopheles minimus and Anopheles sinensis were collected in two towns (Na Bang and Ping Yuan) each month from June to October, 2016. Over the study period, 10,053 Anopheles mosquitoes were collected from the eight towns, and 15 Anopheles species were identified, the most-common of which were An. sinensis (75.4%), Anopheles kunmingensis (15.6%), and An. minimus (3.5%). Anopheles minimus was the major malaria vector in low-elevation areas (malaria in the China-Myanmar border in Yingjiang County.

In this paper, we review our recent research progresses on real-time orthogonal frequency division multiplexing (OFDM) transmission based on FPGA. We successfully demonstrated four-channel wavelength-division multiplexing (WDM) 256.51Gb/s 16-ary quadrature amplitude modulation (16QAM)-OFDM signal transmission system for short-reach optical amplifier free inter-connection with real-time reception. Four optical carriers are modulated by four different 16QAM-OFDM signals via 10G-class direct modulation lasers (DMLs). We achieved highest capacity real-time reception optical OFDM signal transmission over 2.4-km SMF with the bit-error ratio (BER) under soft-decision forward error correction (SD-FEC) limitation of 2.4×10-2. In order to achieve higher spectrum efficiency (SE), we demonstrate 4-channel high level QAM-OFDM transmission over 20-km SMF-28 with real-time reception. 58.72-Gb/s 256QAM-OFDM and 56.4-Gb/s 128QAM-OFDM signal transmission within 25-GHz grid is achieved with the BER under 2.4×10-2 and real-time reception.

The development of field-wide risk based remediation objectives for the aging Devon Canada Swan Hills oil field was examined along with the key components of the closure strategy. These included source removal to the extent practical, long term monitoring, and achievable risk-based remedial objectives that were appropriate to the remote boreal forest setting of the Swan Hills field. A two stage approach was presented. The first stage involved a field wide background framework which included defining areas of common physical and ecological setting and developing appropriate exposure scenarios. The second stage involved site-specific risk assessments which included adjusting for site-specific conditions and an early demonstration project to prove the concept. A GIS approach was used to identify areas of common physical and ecological setting including: physiography; surface water; land use; vegetation ecozones; surficial and bedrock geology; and water well use. Species lists were compiled for vegetation, terrestrial wildlife (mammals, birds, amphibians), and aquatic species (fish and invertebrates). Major contaminant sources, problem formulation, vegetation bioassays, invertebrate bioassays, black spruce emergence, and guideline development were other topics covered during the presentation. Last, a summary of progress was presented. A field-wide review and development of risk zones and site-specific risk assessment has been completed. A regulatory review is underway. tabs., figs.

Information maximization explains the emergence of complex cell-like neurons

Full Text Available We propose models and a method to qualitatively explain the receptive field properties of complex cells in the primary visual cortex. We apply a learning method based on the information maximization principle in a feedforward network, which comprises an input layer of image patches, simple cell-like first-output-layer neurons, and second-output-layer neurons (Model 1. The information maximization results in the emergence of the complex cell-like receptive field properties in the second-output-layer neurons. After learning, second-output-layer neurons receive connection weights having the same size from two first-output-layer neurons with sign-inverted receptive fields. The second-output-layer neurons replicate the phase invariance and iso-orientation suppression. Furthermore, on the basis of these results, we examine a simplified model showing the emergence of complex cell-like receptive fields (Model 2. We show that after learning, the output neurons of this model exhibit iso-orientation suppression, cross-orientation facilitation, and end stopping, which are similar to those found in complex cells. These properties of model neurons suggest that complex cells in the primary visual cortex become selective to features composed of edges to increase the variability of the output.

Full Text Available Neste texto, O objetivo do presente estudo consistiu em analisar a relação do saque e da recepção com o efeito do ataque em seleções nacionais de voleibol juvenil masculino. Recorreu-se à observação e análise de onze jogos, totalizando 781 ações de ataque. Os resultados demonstraram que o ponto no ataque ocorreu mais do que o esperado após o saque suspensão colocado e após a recepção que permitiu todas as opções de ataque. Contrariamente, este ocorreu menos do que o esperado após o saque suspensão potente e a recepção que não permitiu ataque organizado. O presente estudo permitiu inferir que o saque potente e a recepção com baixos níveis de eficácia reduzem as possibilidades de pontuar no ataque. O fato do saque potente adversário induzir menor ocorrência de ponto no ataque, pode sugerir alguma debilidade na organização ofensiva da equipa perante as dificuldades acrescidas colocadas por este tipo de saque.Tal sugere a necessidade de, desde as categorias de base, ser dada maior atenção no treinamento à capacidade das equipas organizarem as manobras ofensivas em resposta a saques agressivos como é o caso do saque suspensão potente.The purpose of this study was to analyze the relationship between serve and serve reception on the effect of the offensive system in the national junior male volleyball teams. Eleven games were analyzes, totaling 781 attack actions. The results showed that the attack point occurred more than expected after the top spin placed jump serve from the opponent and after the reception that allowed all the attack options. In contrast, to this one and the reception that did not allowed an organized attack occurred less than expected after the power jump service. This study made it possible to infer that powerful service and the reception with low levels of efficiency reduce the chances of scoring in the attack. The fact that the opponent's powerful service results lesser occurrences of the

'Welzijn op Recept' is an intervention in which primary care providers refer patients with psychosocial problems to a community well-being organisation. Welzijn op Recept has been helping participants in the town of Nieuwegein, the Netherlands for more than three years. An impact study was carried out from September to December 2014. The qualitative study aimed to determine what happens in the chain of the social prescription and what changes the participant experiences in terms of social participation. The participants in this study were selected by the well-being coaches. A total of 10 semi-structured in-depth interviews were conducted. This study has shown that the participants had confidence in their referral to the community well-being organisation. The well-being coaches constitute a link between primary care providers, patients and the community well-being organisation. Participants have explicitly indicated that they experienced an increase in their own strength, self-confidence, self-reliance and the number of social contacts, and stated that they are experiencing better health. A point of special interest in the current programme is the planning of structured follow-up interviews after starting up an activity.

Factors affecting embryo viability and uterine receptivity: insights from an analysis of the UK registry data.

Many studies have identified prognostic factors for IVF treatment outcome; however, little information is available on the mechanism of their action. Embryo-uterus models have the potential to distinguish between factors acting on the embryo directly and those acting through the uterine environment. Here we apply embryo-uterus models to comprehensive UK registry data from two periods, 2000-2005 and 2007-2011, containing 139,444 and 226,542 embryo transfer cycles, respectively. Given this large dataset, the embryo-uterus model is capable of distinguishing between uterine and embryo effects. Maternal age is the predominant predictor of live birth and acts on both the embryo and uterine components, but with larger effects on the embryo. Prolonged embryo culture is associated with greater embryo viability, reflecting the greater degree of selection, but is also associated with greater uterine receptivity. Cryopreserved embryos are less viable and were associated with poorer uterine receptivity. This work suggests that, in addition to the direct effects of in-vitro culture on the embryonic environment during the first few days of the embryo's life, the delay in transfer after extended culture or cryopreservation can lead to an altered uterine environment for the embryo after transfer.

Rethinking receptivity in a postcolonial context: recasting Sembène's Moolaade

2012-09-01

Full Text Available The main challenge confronting African postcolonial societies is the failure of political, social, and cultural transformation to confront and transcend the limitations imposed by historical and contemporary contingencies. Hence the task of postcolonial theorists is to develop conceptual resources for a more sustained evaluation and analysis of the challenge. In this article, I recast Sembène's film, Moolaade, in a new relief to foreground the core issue of the postcolonial condition. I proceed to reappropriate Kompridis's concepts of ‘reflective disclosure’ and ‘receptivity’, which he develops from Heidegger's ‘world disclosure’, to devise what I term ‘postcolonial receptivity’. I then argue that postcolonial receptivity is an important concept that lends more intelligibility and coherence to the African quest to transform social and political forms of life.

Counting ability in Down syndrome: The comprehension of the one-to-one correspondence principle and the role of receptive vocabulary.

Abreu-Mendoza, Roberto A; Arias-Trejo, Natalia

2017-10-01

The authors investigated whether children with Down's syndrome (DS) who have not started to produce number words understand the one-to-one correspondence principle (Experiment 1), and they looked at the relationship between number word knowledge and receptive vocabulary (Experiment 2). Sixteen children with DS who did not recite the count list participated in Experiment 1, along with 2 comparison groups: 1 of 16 children with DS who recited up to 10, paired by chronological age, and another of 16 typically developing children paired by their ability to recite the list. The understanding of the principle was evaluated by a preferential looking task. Children saw 1 of 2 conditions. In the number condition, they heard number words and in the beep condition they heard computerized beeps. In both conditions, children saw videos depicting counting events that were principle-consistent or principle-inconsistent. Experiment 2 evaluated 25 children with DS using the Give-a-Number task and the Receptive Vocabulary subtest of the Wechsler Preschool and Primary Scale of Intelligence-III. In Experiment 1, children in the number condition preferred principle-consistent videos, independent of their ability to recite the count list. Experiment 2 showed a strong correlation between number word knowledge and receptive vocabulary scores, independent of chronological age. The results suggest that the difficulty of children with DS in acquiring counting ability might not reflect a lack of understanding of the one-to-one correspondence principle, but might instead be related to vocabulary development.

Volume-based Representation of the Magnetic Field

Simulation and reconstruction of events in high-energy experiments require the knowledge of the value of the magnetic field at any point within the detector. The way this information is extracted from the actual map of the magnetic field and served to simulation and reconstruction applications has a large impact on accuracy and performance in terms of speed. As an example, the CMS high level trigger performs on-line tracking of muons within the magnet yoke, where the field is discontinuous and largely inhomogeneous. In this case the high level trigger execution time is dominated by the time needed to access the magnetic field map.For this reason, an optimized approach for the access to the CMS field was developed, based on a dedicated representation of thedetector geometry. The detector is modeled in terms of volumes, constructed in such a way that their boundaries correspond to the fiel d discontinuities due to changes in the magnetic permeability of the materials. The field within each volume is therefore c...

We studied the effects of phenazepam (0.075 mg/kg) after pretreatment (5 minutes before) with naloxone (10 mg/kg) on open-field behavior of C57Bl/6 and BALB/c mice. In ex vivo experiments, we studied the effects of naloxone (1 and 10 mg/kg) on receptor binding of [(3)H]-flunitrazepam by membranes of brain fraction (P1+P2) of C57Bl/6 and BALB/c mice. It was shown that naloxone increased motor activity in the open field in BALB/c mice and decreased this parameter in C57Bl/6 mice. During combined treatment, naloxone potentiated the activating effects of phenazepam on the open-field behavior of BALB/c mice and slightly increased the sedative effect of this drug in C57Bl/6 mice. Naloxone stimulated reception of [(3)H]-flunitrazepam in BALB/c mice and slightly increased radioligand binding in C57Bl/6 mice. These data attest to enhanced reception in benzodiazepine site of GABAA-receptor under conditions of opioid receptor blockade, the presence of anxiolytic or sedative (depending on the phenotype of the response to emotional stress) effect of naloxone, and co-directed effects of naloxone and benzodiazepine tranquilizer on open-field behavior of C57Bl/6 and BALB/c mice.

Macbeth by Giuseppe Verdi and the Romantic reception of William Shakespeare’s drama

Full Text Available Romantic approach to William Shakespeare’s dramatic works, as well as the notions and questions so vital for the consciousness of the epoch concerning the capacity and function of destiny, unrecognizability of existence, interference of supernatural powers in the world that can be grasped with human mind and common sense, are all intriguingly transparent in Giuseppe Verdi’s Macbeth. The Italian composer, who knew the Romantic reception of Shakespeare’s dramatic plays well (e.g. the Italian translations of the lectures given by August W. Schlegel, embarked upon the issue of the ambiguity of the scene with the witches that appear to Macbeth, posed a question on the cognitive value in the dreamy apparition (in the brilliantly constructed Lady Macbeth’s sleepwalking scene, and, finally, emphasized the aspect of hybridity of the world that inseparably combines the grandeur and the grotesque (the point highlighted in Victor Hugo’s considerations on Shakespeare. The two versions of the operatic Macbeth — the one produced in Florence in 1847, the other, 1865 revised version produced for Paris — relate well with the long sequence of changeable conventions in the nineteenth century theatre, taking into consideration its requirements (the need for a spectacular character of staging, the introduction of multiple Ake a Romantic implant in the operetta world of farcical braggadocio dominant on the Parisian stage at the time of the Second Empire, testifies to the enormous influence of the Romantic reception of Shakespeare exerted at the time and defining for a considerable period of time the concept of adaptation of the works of the Stradford master to meet the needs of the operatic stage.

Objectives This study (a) examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of three contrasting types of background music, and (b) compared performance based upon listener groups: CI recipients using conventional long-electrode (LE) devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing (NH) adults. Methods We tested 154 LE CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 NH adults on closed-set recognition of spondees presented in three contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes Signal-to-noise thresholds for speech in music (SRTM) were examined in relation to measures of speech recognition in background noise and multi-talker babble, pitch perception, and music experience. Results SRTM thresholds varied as a function of category of background music, group membership (LE, Hybrid, NH), and age. Thresholds for speech in background music were significantly correlated with measures of pitch perception and speech in background noise thresholds; auditory status was an important predictor. Conclusions Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music. PMID:23342550

Discrete phase space based on finite fields

Gibbons, Kathleen S.; Hoffman, Matthew J.; Wootters, William K.

2004-01-01

The original Wigner function provides a way of representing in phase space the quantum states of systems with continuous degrees of freedom. Wigner functions have also been developed for discrete quantum systems, one popular version being defined on a 2Nx2N discrete phase space for a system with N orthogonal states. Here we investigate an alternative class of discrete Wigner functions, in which the field of real numbers that labels the axes of continuous phase space is replaced by a finite field having N elements. There exists such a field if and only if N is a power of a prime; so our formulation can be applied directly only to systems for which the state-space dimension takes such a value. Though this condition may seem limiting, we note that any quantum computer based on qubits meets the condition and can thus be accommodated within our scheme. The geometry of our NxN phase space also leads naturally to a method of constructing a complete set of N+1 mutually unbiased bases for the state space

[Amateurism in Geology: the French Reception of the Continental Drift Theory (1920-1950)].

Le Vigouroux, Philippe; Gohau, Gabriel

At the beginning of the XXth century, Wegener proposed a theory – that of the roaming drift of the continents – unifying the rival theories of the Europeans and the Americans. As the work of a non-specialist who didn’t trouble himself with specific details, it raised numerous criticisms from specialists in various disciplines though others welcomed and supported it. Some even understood that despite its flaws, it started a new research program. Paradoxically, as regards its simplicity, nonspecialists – engineers, popularizers, secondary school teachers and even believers in para-sciences – gave it a favorable reception. Being amateurs, they continued to endorse it when specialists abandoned it.

Weakly electric fish sense their surroundings in complete darkness by their active electric field detection system. However, due to the insufficient detection capacity of the electric field, the detection distance is not enough, and the detection accuracy is not high. In this paper, a method of underwater detection based on rotating current field theory is proposed to improve the performance of underwater electric field detection system. First of all, we built underwater detection system based on the theory of the spin current field mathematical model with the help of the results of previous researchers. Then we completed the principle prototype and finished the metal objects in the water environment detection experiments, laid the foundation for the further experiments.
