    This study presents the results of the adaptation of the International Affective Picture System (IAPS) for European Portuguese (EP). Following the original procedure of Lang et al., 2000 native speakers of EP rated the 1,182 pictures of the last version of the IAPS set on the three affective dimensions of valence, arousal, and dominance, using the Self-Assessment Manikin (SAM). Results showed that the normative values of the IAPS for EP are properly distributed in the affective space of valence and arousal, showing the typical boomerang-shaped distribution observed in previous studies. Results also point to important differences in the way Portuguese females and males react to affective pictures that should be taken into consideration when planning and conducting research with Portuguese samples. Furthermore, the results from the cross-cultural comparisons between the EP ratings and the ratings from the American, Spanish, Brazilian, Belgian, Chilean, Indian, and Bosnian-Herzegovinian standardizations, showed that in spite of the fact that IAPS stimuli elicited affective responses that are similar across countries and cultures (at least in Western cultures), there are differences in the way Portuguese individuals react to IAPS pictures that strongly recommend the use of the normative values presented in this work.

    There is a need to use selected pictures with pure emotion as stimulation or treatment media for basic and clinical research. Pictures from the widely-used International Affective Picture System (IAPS) contain rich emotions, but no study has clearly stated that an emotion is exclusively expressed in its putative IAPS picture to date. We hypothesize that the IAPS images contain at least pure vectors of disgust, erotism (or erotica), fear, happiness, sadness and neutral emotions. Accordingly, we have selected 108 IAPS images, each with a specific emotion, and invited 219 male and 274 female university students to rate only the intensity of the emotion conveyed in each picture. Their answers were analyzed using exploratory and confirmatory factor analysis. Four first-order factors manifested as disgust-fear, happiness-sadness, erotism, and neutral. Later, ten second-order sub-factors manifested as mutilation-disgust, vomit-disgust, food-disgust, violence-fear, happiness, sadness, couple- erotism, female-erotism, male- erotism, and neutral. Fifty-nine pictures for the ten sub-factors, which had established good model-fit indices, satisfactory sub-factor internal reliabilities, and prominent gender-differences in the picture intensity ratings were ultimately retained. We thus have selected a series of pure-emotion IAPS pictures, which together displayed both satisfactorily convergent and discriminant structure-validities. We did not intend to evaluate all IAPS items, but instead selected some pictures conveying pure emotions, which might help both basic and clinical researches in the future.

    Full Text Available INTRODUÇÃO: A literatura científica indica a possibilidade de a percepção da emoção e a formação da memória emocional serem discordantes entre jovens e idosos. A mesma é pobre ao explorar essa possibilidade. Neste estudo, relatamos os resultados obtidos em um experimento-piloto com uma amostra de idosos brasileiros, que classificaram subjetivamente, através da escala Self Assessment Manikin, imagens oriundas do International Affective Picture System. MÉTODO: Quarenta e oito idosos voluntários da Universidade Aberta da Terceira Idade, saudáveis clínica e cognitivamente, avaliaram o caráter alertante e a valência afetiva de 71 imagens do International Affective Picture System, aleatoriamente escolhidas. RESULTADOS: O grau de alerta reportado por idosos diante de um estímulo emocional é tanto maior quanto menor o prazer provocado por essa imagem-estímulo, resultando na existência de uma forte correlação negativa (r = 0,93 entre o grau de alerta e o estímulo desprazeroso. Em uma comparação do acima obtido com outro experimento normativo semelhante feito com jovens brasileiros e americanos, apontou-se para uma possível diferença cultural na forma de relatar subjetivamente um estímulo emocional. CONCLUSÕES: Os resultados obtidos com esta amostra estudada sugerem que pode existir uma diferença nos relatos afetivos entre os jovens e idosos, onde uma normatização do International Affective Picture System para uma amostra maior, representativa da população de idosos, seria útil para responder esta questão.INTRODUCTION: The scientific literature points to a possible bias in the form perception and emotional memory are constructed when elderly and young individuals are compared.

  5. Sustained Attention Ability Affects Simple Picture Naming

    Full Text Available Sustained attention has previously been shown as a requirement for language production. However, this is mostly evident for difficult conditions, such as a dual-task situation. The current study provides corroborating evidence that this relationship holds even for simple picture naming. Sustained attention ability, indexed both by participants’ reaction times and individuals’ hit rate (the proportion of correctly detected targets on a digit discrimination task, correlated with picture naming latencies. Individuals with poor sustained attention were consistently slower and their RT distributions were more positively skewed when naming pictures compared to individuals with better sustained attention. Additionally, the need to sustain attention was manipulated by changing the speed of stimulus presentation. Research has suggested that fast event rates tax sustained attention resources to a larger degree than slow event rates. However, in this study the fast event rate did not result in increased difficulty, neither for the picture naming task nor for the sustained attention task. Instead, the results point to a speed-accuracy trade-off in the sustained attention task (lower accuracy but faster responses in the fast than in the slow event rate, and to a benefit for faster rates in the picture naming task (shorter naming latencies with no difference in accuracy. Performance on both tasks was largely comparable, supporting previous findings that sustained attention is called upon during language production.

    It is hypothesized that ratings of emotional stimuli are affected by a constant threat of traumatic events. Ratings of valence and arousal on the International Affective Picture System from young adults in the United States were compared to those of young Israeli adults. Israelis rated the pictures as less negative and less positive than did participants from the United States. Israeli women gave higher arousal ratings compared to the American women. These differences may be due to compulsory military service in Israel, during which exposure to traumatic events is more likely to occur, and to the timing of the study which followed a year of frequent suicide bomb attacks. The authors suggest that these findings may reflect mild symptoms of stress disorders. Copyright © 2011 International Society for Traumatic Stress Studies.

  7. Bonding Pictures: Affective Ratings Are Specifically Associated to Loneliness But Not to Empathy

    Full Text Available Responding to pro-social cues plays an important adaptive role in humans. Our aims were (i to create a catalog of bonding and matched-control pictures to compare the emotional reports of valence and arousal with the International Affective Picture System (IAPS pictures; (ii to verify sex influence on the valence and arousal of bonding and matched-control pictures; (iii to investigate if empathy and loneliness traits exert a specific influence on emotional reports for the bonding pictures. To provide a finer tool for social interaction studies, the present work defined two new sets of pictures consisting of “interacting dyads” (Bonding: N = 70 and matched controls “non-interacting dyads” (Controls: N = 70. The dyads could be either a child and an adult, or two children. Participants (N = 283, 182 women were divided in 10 groups for the experimental sessions. The task was to rate the hedonic valence and emotional arousal of bonding and controls; and of pleasant, neutral, and unpleasant pictures from the IAPS. Effects of social-related traits, empathy and loneliness, on affective ratings were tested. Participants rated bonding pictures as more pleasant and arousing than control ones. Ratings did not differentiate bonding from IAPS pleasant pictures. Control pictures showed lower ratings than pleasant but higher ratings than neutral IAPS pictures. Women rated bonding and control pictures as more positive than men. There was no sex difference for arousal ratings. High empathic participants rated bonding and control pictures higher than low empathic participants. Also, they rated pleasant IAPS pictures more positive and arousing; and unpleasant pictures more negative and arousing than the less empathic ones. Loneliness trait, on the other hand, affected very specifically the ratings of bonding pictures; lonelier participants rated them less pleasant and less arousing than less lonely. Loneliness trait did not modulate ratings of other

  8. Affective Pictures and the Open Library of Affective Foods (OLAF): Tools to Investigate Emotions toward Food in Adults.

    Recently, several sets of standardized food pictures have been created, supplying both food images and their subjective evaluations. However, to date only the OLAF (Open Library of Affective Foods), a set of food images and ratings we developed in adolescents, has the specific purpose of studying emotions toward food. Moreover, some researchers have argued that food evaluations are not valid across individuals and groups, unless feelings toward food cues are compared with feelings toward intense experiences unrelated to food, that serve as benchmarks. Therefore the OLAF presented here, comprising a set of original food images and a group of standardized highly emotional pictures, is intended to provide valid between-group judgments in adults. Emotional images (erotica, mutilations, and neutrals from the International Affective Picture System/IAPS) additionally ensure that the affective ratings are consistent with emotion research. The OLAF depicts high-calorie sweet and savory foods and low-calorie fruits and vegetables, portraying foods within natural scenes matching the IAPS features. An adult sample evaluated both food and affective pictures in terms of pleasure, arousal, dominance, and food craving, following standardized affective rating procedures. The affective ratings for the emotional pictures corroborated previous findings, thus confirming the reliability of evaluations for the food images. Among the OLAF images, high-calorie sweet and savory foods elicited the greatest pleasure, although they elicited, as expected, less arousal than erotica. The observed patterns were consistent with research on emotions and confirmed the reliability of OLAF evaluations. The OLAF and affective pictures constitute a sound methodology to investigate emotions toward food within a wider motivational framework. The OLAF is freely accessible at digibug.ugr.es.

    The current study provides a comprehensive evaluation of critical psychometric properties of commonly used psychophysiology laboratory tasks/measures within the NIMH RDoC. Participants (N = 128) completed the no-shock, predictable shock, unpredictable shock (NPU) task, affective picture viewing task, and resting state task at two study visits separated by 1 week. We examined potentiation/modulation scores in NPU (predictable or unpredictable shock vs. no-shock) and affective picture viewing tasks (pleasant or unpleasant vs. neutral pictures) for startle and corrugator responses with two commonly used quantification methods. We quantified startle potentiation/modulation scores with raw and standardized responses. We quantified corrugator potentiation/modulation in the time and frequency domains. We quantified general startle reactivity in the resting state task as the mean raw startle response during the task. For these three tasks, two measures, and two quantification methods, we evaluated effect size robustness and stability, internal consistency (i.e., split-half reliability), and 1-week temporal stability. The psychometric properties of startle potentiation in the NPU task were good, but concerns were noted for corrugator potentiation in this task. Some concerns also were noted for the psychometric properties of both startle and corrugator modulation in the affective picture viewing task, in particular, for pleasant picture modulation. Psychometric properties of general startle reactivity in the resting state task were good. Some salient differences in the psychometric properties of the NPU and affective picture viewing tasks were observed within and across quantification methods. © 2016 The Authors.

    Visually induced analgesia has been correlated with the affective content of pleasant, neutral or unpleasant pictures. The aim of the present study was to assess the effect of affective images vision on laser evoked potentials and pain perception, in a cohort of healthy subjects and migraine patients. Twenty-two healthy subjects and 24 migraine without aura patients (recorded during the inter-critical phase) participated in the study. Eighty-four colour slides, arranged in two blocks, each consisting of 14 pleasant, 14 unpleasant and 14 neutral images, in random presentation, were chosen from the International Affective Picture System. The CO(2) laser stimuli were delivered on the dorsum of the right hand and supra-orbital zone at 7.5-watt intensity and 25-ms duration, in basal condition and during the viewing of affective pictures. Migraine patients expressed higher scores of valence and arousal for pleasant and unpleasant pictures, compared to controls. In both groups, a late positive potential in the 400-700 ms time range was clear for pleasant and unpleasant pictures, but its amplitude was significantly reduced in migraine patients. The pain rating and the N2 component were reduced in both groups during the visual task compared to basal condition. In migraineurs and controls the P2 wave was reduced during the vision of pleasant pictures, compared to basal condition. This indicates that stimulation by images with different affective content reduces subjective pain for a cognitive mechanism of attentive engagement, while a special inhibition of later LEPs is produced by a positive emotional impact. In migraine, affective images are able to modulate pain perception and LEPs, differently from other modalities of distraction, suggesting a possible emotive elaboration of painful stimuli.

    Music is an intriguing stimulus widely used in movies to increase the emotional experience. However, no brain imaging study has to date examined this enhancement effect using emotional pictures (the modality mostly used in emotion research) and musical excerpts. Therefore, we designed this functional magnetic resonance imaging study to explore how musical stimuli enhance the feeling of affective pictures. In a classical block design carefully controlling for habituation and order effects, we presented fearful and sad pictures (mostly taken from the IAPS) either alone or combined with congruent emotional musical excerpts (classical pieces). Subjective ratings clearly indicated that the emotional experience was markedly increased in the combined relative to the picture condition. Furthermore, using a second-level analysis and regions of interest approach, we observed a clear functional and structural dissociation between the combined and the picture condition. Besides increased activation in brain areas known to be involved in auditory as well as in neutral and emotional visual-auditory integration processes, the combined condition showed increased activation in many structures known to be involved in emotion processing (including for example amygdala, hippocampus, parahippocampus, insula, striatum, medial ventral frontal cortex, cerebellum, fusiform gyrus). In contrast, the picture condition only showed an activation increase in the cognitive part of the prefrontal cortex, mainly in the right dorsolateral prefrontal cortex. Based on these findings, we suggest that emotional pictures evoke a more cognitive mode of emotion perception, whereas congruent presentations of emotional visual and musical stimuli rather automatically evoke strong emotional feelings and experiences.

  12. Picture yourself at the polls: visual perspective in mental imagery affects self-perception and behavior.

    The present research demonstrates that the visual perspective--own first-person versus observer's third-person--people use to picture themselves engaging in a potential future action affects their self-perceptions and subsequent behavior. On the eve of the 2004 U.S. presidential election, registered voters in Ohio were instructed to use either the first-person or the third-person perspective to picture themselves voting in the election. Picturing voting from the third-person perspective caused subjects to adopt a stronger pro-voting mind-set correspondent with the imagined behavior. Further, this effect on self-perception carried over to behavior, causing subjects who were instructed to picture voting from the third-person perspective to be significantly more likely to vote in the election. These findings extend previous research in autobiographical memory and social judgment linking the observer's perspective with dispositional attributions, and demonstrate the causal role of imagery in determining future behavior.

    For the last decade, solar-acoustic oscillations have been used to probe the physical properties of the solar interior. The endeavor is called helioseismology and is based on the fact that shifts in the frequency of an oscillation mode, as observed at the surface, contain information about the physical environment in those regions of the interior where the oscillation has energy. The thesis describes a helioseismic quest to determine the angular velocity inside the Sun as a function of depth and latitude. The author has analyzed rotational frequency splittings extracted from 15 days of full-disk observations of the solar-acoustic oscillations (l=15-99) obtained with the Fourier Tachometer (a Doppler analyzing instrument designed by Tim Brown). The observed frequency splittings are compared to those generated by several different physically-motivated models for the solar internal angular velocity

    Psychopathic offenders are described as emotionally cold, displaying deficits in affective responding. However, research demonstrates that many of the psychopathy-related deficits are moderated by attention, such that under conditions of high attentional and perceptual load psychopathic offenders display deficits in affective responses, but do not in conditions of low load. To date, most studies use measures of defensive reflex (i.e., startle) and conditioning manipulations to examine the impact of load on psychopathy-related processing, but have not examined more direct measures of attention processing. In a sample of adult male offenders, the present study examined time-frequency EEG phase coherence in response to a picture-viewing paradigm that manipulated picture familiarity to assess neural changes in processing based on perceptual demands. Results indicated psychopathy-related differences in the theta response, an index of readiness to perceive and integrate sensory information. These data provide further evidence that psychopathic offenders have disrupted integration of sensory information. Copyright © 2016 Elsevier B.V. All rights reserved.

  15. Food depictions in picture books for preschool children: Frequency, centrality, and affect.

    The food content and messages depicted in popular children's picture books were examined using a set of 100 "Favorite Books for Preschoolers." Sixty-nine of these books depicted food and comprised the sample. Examined were: the types and frequencies of food depicted in the text and/or illustrations of the books; the centrality (central, background); and the affect (positive, neutral, or negative) of those depictions. Each food item was counted, categorized by type, and where possible, coded for centrality and affect. Fruit was the most frequently depicted food, followed by sweetened baked goods, dairy, and vegetables. However, centrality and affect differed for these foods. For example, sweet baked goods were high in both centrality and affect. In contrast vegetables were relatively high in centrality but most often neutral in affect. Ice cream, although not in many books, always was associated with positive outcomes. Results were compared to findings in the literature on food messages presented in children's television programs. The ratio of healthy foods to nutrient-poor foods was higher in the books. However, as in television, the books emphasized the desirability of sweetened foods. The results point to the need for detailed analyses of the types of presentations associated with different foods presented in books for children, as well as for continued investigations into food messages in the growing range of media available to young children.

    Picture books are ubiquitous in young children's lives and are assumed to support children's acquisition of information about the world. Given their importance, relatively little research has directly examined children's learning from picture books. We report two studies examining children's acquisition of labels and facts from picture books that vary on two dimensions: iconicity of the pictures and presence of manipulative features (or "pop-ups"). In Study 1, 20-month-old children generalized novel labels less well when taught from a book with manipulative features than from standard picture books without such elements. In Study 2, 30- and 36-month-old children learned fewer facts when taught from a manipulative picture book with drawings than from a standard picture book with realistic images and no manipulative features. The results of the two studies indicate that children's learning from picture books is facilitated by realistic illustrations, but impeded by manipulative features.

    Self-reported affect to positive and negative emotional pictures was contrasted in people with major depressive disorder (MDD) and never-depressed control participants (n = 25 in each group). The results revealed significant differences in response to positive images (reduced arousal, less pleasant valence, decreased happiness, increased sadness) in MDD but no clear group differences in response to negative stimuli. Extending earlier findings of reduced responsiveness to positive, but not negative, stimuli in MDD (D. M. Sloan, M. E. Strauss, S. W. Quirk, & M. Satajovik, 1997; D. M. Sloan, M. E. Strauss, & K. L. Wisner, 2001), the data indicate that blunted response to positive stimuli is found when both categorical and dimensional ratings are elicited. Further, the data replicate earlier findings of elevated sadness reports to positive stimuli (J. Rottenberg, K. L. Kasch, J. J. Gross, & I. H. Gotlib, 2002), which may reflect broader difficulties in regulating emotions in MDD. Copyright 2004 APA.

    Exposure to video game violence (VGV) is known to result in desensitization to violent material and may alter the processing of positive emotion related to facial expressions. The present study was designed to address three questions: (1) Does the association between VGV and positive emotion extend to stimuli other than faces, (2) is the association between VGV and affective picture processing observed with a single presentation of the stimuli, and (3) is the association between VGV and the response to violent stimuli sensitive to the relevance of emotion for task performance? The data revealed that transient modulations of the event-related potentials (ERPs) related to attentional orienting and sustained modulations of the ERPs related to evaluative processing were sensitive to VGV exposure.

    Full Text Available The vocational activities of doctors and their social status do not ensure their health. And, falling ill, doctors don’t identify themselves with ordinary patients as they have a deep knowledge of medicine. Thus, the internal picture of a doctor’s illness is both a research and a practical problem: the problem of the psychoprevention of doctors’ illnesses at all stages of their professionalization. The purpose of the research was to study the phenomenological features of the internal picture of doctors’ illnesses using the structural approach. The total number of participants was 132. The experimental group consisted of 66 sick doctors, differentiated according to their stage of professionalization: vocational training (students, professional adaptation (interns, full professionalization (doctors. The control group consisted of 66 people who did not have any medical education. All the control subjects were hospitalized with chronic diseases during the study period. The organization of the research was carried out with the use of clinical-psychological and diagnostic methods, the methods of descriptive statistics, and comparative, multidimensional, and structural analysis. The research revealed the following phenomenological features of the internal picture of doctors’ illnesses: the prevalence of some anxiety in the doctors and high awareness of their health; the doctors’ altruistic orientation; their willingness to work despite difficulties; and their ability to achieve high results in different activities. The structural features of the doctors’ image of their own diseases on the cognitive level were the following: qualitative heterogeneity during in-service activities; a high degree of image integration during in-service activities; and stereotyped perceptions of the disease. The emotional level revealed the emotional distance between doctors and their patients, and the behavioral level revealed doctors’ disregard for the

    Organ transplantation is widely practised worldwide. The expansion of organ transplantation has led to a critical shortage of organs and the development of the organ trade. Many patients travel to areas where organs are obtainable through commercial transactions. Although the international organ trade is regarded as an important health policy issue, its current state remains obscure because of scarce data and the lack of efforts to synthesize available data. This paper is an attempt to integrate information about the current international organ trade and create a tentative global picture based on a systematic review of 309 media reports, journal articles and other documents. The international organ trade is described in terms of its forms, the organ-exporting countries, the organ-importing countries and its outcomes and consequences.

    International student enrolment in Canadian universities is increasing. As international university students acculturate, they experience a culture shock in which food plays a major role. International university students' Canadian food experiences therefore were explored. A Photovoice methodology was used with 15 international undergraduate and graduate university students, who were recruited to take pictures of their food experiences. They also participated in two focus group discussions that included an analysis of their photos. Seven themes related to the significance of food in acculturation were revealed: the paradox of Canadian convenience, the equation of traditional foods with health, traditional food quality and accessibility, support networks, food consumption for comfort, ethnic restaurants, and the exploration of non-traditional foods. Maintaining cultural identity with traditional foods was an overarching theme related to acculturation. International students acculturating to Canada have emotional and physical needs, which can be met through food. Opportunities exist to improve their acculturation experiences. Canadian universities can incorporate food acculturation strategies into campus events and menus. Nutrition professionals on campus can facilitate a positive food environment and nurture culture identity formation.

    Full Text Available Research on the processing of sexual stimuli has proved that such material has high priority in human cognition. Yet, although sex differences in response to sexual stimuli were extensively discussed in the literature, sexual orientation was given relatively little consideration, and material suitable for relevant research is difficult to come by. With this in mind, we present a collection of 200 erotic images, accompanied by their self-report ratings of emotional valence and arousal by homo- and heterosexual males and females (n = 80, divided into four equal-sized subsamples. The collection complements the Nencki Affective Picture System (NAPS and is intended to be used as stimulus material in experimental research. The erotic images are divided into five categories, depending on their content: opposite-sex couple (50, male couple (50, female couple (50, male (25 and female (25. Additional 100 control images from the NAPS depicting people in a non-erotic context were also used in the study. We showed that recipient sex and sexual orientation strongly influenced the evaluation of erotic content. Thus, comparisons of valence and arousal ratings in different subject groups will help researchers select stimuli set for the purpose of various experimental designs. To facilitate the use of the dataset, we provide an on-line tool, which allows the user to browse the images interactively and select proper stimuli on the basis of several parameters. The NAPS ERO image collection together with the data are available to the scientific community for non-commercial use at http://naps.nencki.gov.pl.

    Recent neuroscience findings demonstrate the fundamental role of emotion in the maintenance of physical and mental health. In the present study, a novel architecture is proposed for the robust discrimination of emotional physiological signals evoked upon viewing pictures selected from the International Affective Picture System (IAPS). Biosignals are multichannel recordings from both the central and the autonomic nervous systems. Following the bidirectional emotion theory model, IAPS pictures are rated along two dimensions, namely, their valence and arousal. Following this model, biosignals in this paper are initially differentiated according to their valence dimension by means of a data mining approach, which is the C4.5 decision tree algorithm. Then, the valence and the gender information serve as an input to a Mahalanobis distance classifier, which dissects the data into high and low arousing. Results are described in Extensible Markup Language (XML) format, thereby accounting for platform independency, easy interconnectivity, and information exchange. The average recognition (success) rate was 77.68% for the discrimination of four emotional states, differing both in their arousal and valence dimension. It is, therefore, envisaged that the proposed approach holds promise for the efficient discrimination of negative and positive emotions, and it is hereby discussed how future developments may be steered to serve for affective healthcare applications, such as the monitoring of the elderly or chronically ill people.

    1996-01-01

    We made a new mathematical phantom using the patients' digital pictures of bone scintillation in nuclear medicine. The data of 99m Tc bone scintillation pictures include the information on the body sizes and shapes. In the bone scintillation pictures, no three dimensional data are available, so that the shapes and sizes of whole body and bones were modelled based on standard anatomical geometry. The organs except bone were also modelled after construction of the bone mathematical model. The mathematical phantoms were developed for each patient. The specific effective energy for each phantom can be calculated by the Monte Carlo code to compare it among the patients. Our mathematical phantoms would provide new calculation of internal doses from radiopharmaceuticals in place of the MIRD phantom. (author)

  11. More than pretty pictures? How illustrations affect parent-child story reading and children's story recall.

    Greenhoot, Andrea Follmer; Beyer, Alisa M; Curtis, Jennifer

    2014-01-01

    Previous research showed that story illustrations fail to enhance young preschoolers' memories when they accompany a pre-recorded story (e.g., Greenhoot and Semb, 2008). In this study we tested whether young children might benefit from illustrations in a more interactive story-reading context. For instance, illustrations might influence parent-child reading interactions, and thus children's story comprehension and recall. Twenty-six 3.5- to 4.5-year-olds and their primary caregivers were randomly assigned to an Illustrated or Non-Illustrated story-reading condition, and parents were instructed to "read or tell the story" as they normally would read with their child. Children recalled the story after a distracter and again after 1 week. Analyses of the story-reading interactions showed that the illustrations prompted more interactive story reading and more parent and child behaviors known to predict improved literacy outcomes. Furthermore, in the first memory interview, children in the Illustrated condition recalled more story events than those in the Non-Illustrated condition. Story reading measures predicted recall, but did not completely account for picture effects. These results suggest that illustrations enhance young preschoolers' story recall in an interactive story reading context, perhaps because the joint attention established in this context supports children's processing of the illustrations.

  15. Affective priming of emotional pictures in parafoveal vision: left visual field advantage.

    Science.gov (United States)

    Calvo, Manuel G; Avero, Pedro

    2008-03-01

    This study investigated whether stimulus affective content can be extracted from visual scenes when these appear in parafoveal locations of the visual field and are foveally masked, and whether there is lateralization involved. Parafoveal prime pleasant or unpleasant scenes were presented for 150 msec 2.5 degrees away from fixation and were followed by a foveal probe scene that was either congruent or incongruent in emotional valence with the prime. Participants responded whether the probe was emotionally positive or negative. Affective priming was demonstrated by shorter response latencies for congruent than for incongruent prime-probe pairs. This effect occurred when the prime was presented in the left visual field at a 300-msec prime-probe stimulus onset asynchrony, even when the prime and the probe were different in physical appearance and semantic category. This result reveals that the affective significance of emotional stimuli can be assessed early through covert attention mechanisms, in the absence of overt eye fixations on the stimuli, and suggests that right-hemisphere dominance is involved.

Life has been able to adapt and spread into every planetary nook and cranny. At this point in history, life is becoming able to engineer itself, with extreme consequences we are only dimly able to foresee. One probable outcome will be the facilitation of the expansion of the range of life to beyond our planetary cradle, an evolutionary step as profound as the ancient transition from sea to land. Current efforts at NASA and aboard the International Space Station will be discussed in this context.

  19. A Sensitive and Specific Neural Signature for Picture-Induced Negative Affect.

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Neuroimaging has identified many correlates of emotion but has not yet yielded brain representations predictive of the intensity of emotional experiences in individuals. We used machine learning to identify a sensitive and specific signature of emotional responses to aversive images. This signature predicted the intensity of negative emotion in individual participants in cross validation (n =121 and test (n = 61 samples (high-low emotion = 93.5% accuracy. It was unresponsive to physical pain (emotion-pain = 92% discriminative accuracy, demonstrating that it is not a representation of generalized arousal or salience. The signature was comprised of mesoscale patterns spanning multiple cortical and subcortical systems, with no single system necessary or sufficient for predicting experience. Furthermore, it was not reducible to activity in traditional "emotion-related" regions (e.g., amygdala, insula or resting-state networks (e.g., "salience," "default mode". Overall, this work identifies differentiable neural components of negative emotion and pain, providing a basis for new, brain-based taxonomies of affective processes.

    Full Text Available The article is devoted to the analysis of socio-demographic and individual psychological characteristics that influence the verdict of jury. The study involved 38 men and women aged 25 to 64 years. With the help of a questionnaire, developed on the basis of legal development model by J. Tapp and F. Levine, we revealed levels of jury members’ legal conscience, which, together with socio-demographic characteristics and personality characteristics of the subjects, identified by R. Cattell 16PF Questionnaire, were related to the responses on the Questionnaire while returning verdict on specially selected criminal cases with implicit guilt of the defendant. According to the study, it was determined that the socio-demographic characteristics of the jurors did not significantly affect their verdict, and among the psychological characteristics of the jurors the greatest impact on their verdict has the level of legal development. Thus, depending on the nature of the crime (violent, non-violent or committed through negligence, the same level of legal conscience differently affect the decision of jurors.

    2016-01-01

    Recent work has identified links between mothers’ self-regulation and emotion regulation (ER) and children’s social-emotional outcomes. However, associations between maternal ER strategies (e.g., reappraisal, suppression), known to influence internalizing problems in adults, and children’s negative affect (NA) have not been considered. In the current study, the direct and indirect relationships, through maternal internalizing problems, between maternal use of ER strategies and infant NA are examined. The potential effects of infant NA on maternal internalizing difficulties are also considered. Ninety-nine mothers and their infants participated across three time points during the first year postpartum. Higher maternal suppression was indirectly related to higher infant NA, through maternal internalizing problems; lower maternal reappraisal also was indirectly related to higher infant NA through maternal internalizing problems. Infant NA at four months postpartum was related to mothers’ internalizing problems 6 months postpartum. The implications of these findings for future research and intervention are discussed.

  4. Food as Risk: How Eating Habits and Food Knowledge Affect Reactivity to Pictures of Junk and Healthy Foods.

    Science.gov (United States)

    Yegiyan, Narine S; Bailey, Rachel L

    2016-01-01

    This study explores how people respond to images of junk versus healthy food as a function of their eating habits and food knowledge. The experiment reported here proposed and tested the idea that those with unhealthy eating habits but highly knowledgeable about healthy eating would feel more positive and also more negative toward junk food images compared to images of healthy food because they may perceive them as risky--desirable but potentially harmful. The psychophysiological data collected from participants during their exposure to pictures of junk versus healthy food supported this idea. In addition, unhealthy eaters compared to healthy eaters with the same degree of food knowledge responded more positively to all food items. The findings are critical from a health communication perspective. Because unhealthy eaters produce stronger emotional responses to images of junk food, they are more likely to process information associated with junk food with more cognitive effort and scrutiny. Thus, when targeting this group and using images of junk food, it is important to combine these images with strong message claims and relevant arguments; otherwise, if the arguments are perceived as irrelevant or weak, the motivational activation associated with junk food itself may transfer into an increased desire to consume the unhealthy product.

    Full Text Available Due to rising competition in the international construction market, competitive strategies are becoming ever more important. This study aims to identify the level of importance of a variety of competitive strategies in construction companies to create a theoretical framework for competitive strategies in international construction business. In the questionnaire titled: ‘Identifying the Parameters of Strategic Performance Comparison Tool in International Construction Companies’, professionals were asked the level of importance of parameters in acquiring a competitive edge in international markets for construction companies. 82 people who currently work for international construction companies responded the questionnaire. The Relative Importance Index (RII of competitive strategies in construction companies was calculated using the survey results. The construct was redesigned through the Pearson Correlation and principal components analysis (PCA. The results of the PCA denoted that the construct of competitive strategies in construction companies can be explained by three main factors in sync with Porter’s three generic competitive strategy types: F1 Cost Leadership in Construction, F2 Specialization and Focus and F3 Differentiation in Construction and Company Resources. The analysis results show that the competitive strategies related to “Differentiation in Construction and Company Resources” have a greater importance level, while the diversification strategies have a lower importance level. Which means specialization in some type of construction activity and focus on a specific group of customers is more effective than diversification strategies in gaining a competitive advantage in the market.

    2017-01-01

    Full Text Available The expansion of internet access, high-speed connection services, collaborative work platforms and tools, allowed employees to interact virtually offering companies the possibility to develop projects around the world, reducing operational costs and gain competitive advantage. Realizing the advantages and disadvantages of developing a project team in an international virtual work environment, requires adopting specific strategies to construct an effective team and ensure the project success. One of the most important disadvantages that we identified is that the new work environment brings new risks for both team members and managers. So, it becomes mandatory to identify and analyze the occupational emerging risks and their impact on the productivity of virtual team members, in order to prevent them efficiently and to ensure the safety and health of employees in a virtual working environment. This paper aims to highlight the necessity for project managers and organizations, to include in their specific project strategies, an efficient occupational risks management in the virtual workplace, to obtain a continuously improved virtual working environment, so to achieve a high performance from virtual employees.

    1991-12-01

    This study examined relations among preschoolers' sibling-directed internal state language, perspective-taking abilities, and sibling-directed affective behaviors in 32 sibling dyads (aged 14 months and 3-4 years) during naturalistic home observations. Preschooler references about internal states (emotions, wants, abilities) were significantly more likely to be (a) about the toddler than the self, and (b) made in the mother's absence and during sibling conflict and play. Relative to poor perspective takers, skillful perspective takers (a) engaged in more instances of internal state discourse and (b) talked more frequently about both the toddler and themselves. Preschoolers engaging in high levels of positive affective behavior also spoke more frequently about internal states than children engaging in low levels of positive affective behavior. Discussion of results highlights the notion that internal state language may be one way of regulating sibling interaction and also a potential means for siblings to construct shared meanings about their world.

    Maternal anxiety during pregnancy can negatively affect fetal neurodevelopment, predisposing the offspring to a higher risk of behavioral and emotional problems later in life. The current study investigates the association between maternal anxiety during pregnancy and child affective picture processing using event-related brain potentials (ERPs). Mothers reported anxiety during the second trimester using the anxiety subscale of the Symptom Checklist (SCL-90). At age 4 years, child affective picture processing (N = 86) was measured by recording ERPs during viewing of neutral, pleasant, and unpleasant pictures selected from the International Affective Pictures System. The late positive potential (LPP)-an ERP component reflecting individual differences in affective processing-was used as child outcome. The expected positive association between maternal anxiety and LPP amplitude for unpleasant pictures was not found. Nevertheless, we found a positive association between maternal anxiety during pregnancy and LPP amplitudes for neutral pictures in the middle and late time window at anterior locations (all p age at birth and after FDR correction for multiple comparisons. Our study provides neurophysiological evidence that children prenatally exposed to higher maternal anxiety devote more attentional resources to neutral pictures, but not to unpleasant pictures. Possibly, these children show enhanced vigilance for threat when viewing neutral pictures. Although useful in dangerous environments, this enhanced vigilance may predispose children prenatally exposed to higher maternal anxiety to developing behavioral and/or emotional problems later in life.

    The 5th International Conference on Biophotonics (ICOB) held April 30 to May 1, 2017, in Fremantle, Western Australia, brought together opinion leaders to discuss future directions for the field and opportunities to consider. The first session of the conference, "How to Set a Big Picture Biophotonics Agenda," was focused on setting the stage for developing a vision and strategies for translation and impact on society of biophotonic technologies. The invited speakers, panelists, and attendees engaged in discussions that focused on opportunities and promising applications for biophotonic techniques, challenges when working at the confluence of the physical and biological sciences, driving factors for advances of biophotonic technologies, and educational opportunities. We share a summary of the presentations and discussions. Three main themes from the conference are presented in this position paper that capture the current status, opportunities, challenges, and future directions of biophotonics research and key areas of applications: (1) biophotonics at the nano- to microscale level; (2) biophotonics at meso- to macroscale level; and (3) biophotonics and the clinical translation conundrum.

  1. Does human migration affect international trade? A complex-network perspective.

    Directory of Open Access Journals (Sweden)

    Giorgio Fagiolo

    Full Text Available This paper explores the relationships between international human migration and merchandise trade, using a complex-network approach. We firstly compare the topological structure of worldwide networks of human migration and bilateral trade over the period 1960-2000. Next, we ask whether the position of any pair of countries in the migration network affects their bilateral trade flows. We show that: (i both weighted and binary versions of the networks of international migration and trade are strongly correlated; (ii such correlations can be mostly explained by country economic/demographic size and geographical distance; and (iii pairs of countries that are more central in the international-migration network trade more. Our findings suggest that bilateral trade between any two countries is not only affected by the presence of migrants from either countries but also by their relative embeddedness in the complex web of corridors making up the network of international human migration.

    Full Text Available The aim of this paper is to present a model of the factors affecting international students’ pursuit of their academic degrees in tertiary institutions. This was achieved by identifying factors that commonly affect international postgraduate students. This was a questionnaire based case study with a sample of 24 post-graduate international students from one university in KwaZulu-Natal. Questionnaires were analysed using SPSS (version 21.0 and WarpPLS (4.0. WarpPLS (4.0 was used to draw up a statistically based model regarding the factors affecting international students in pursuit of their academic degrees. Results from the model show that financial stress, accommodation challenges, cultural shock, loneliness/homesick, communication skills and evaluation of their (previous university experience affect students in their pursuit of their academic degrees in higher education. These findings could be used by students themselves to make them aware of possible challenges that lie ahead as well as by staff in international student offices at higher education institutions.

  3. Knowledge internalization and product development in family firms : When relational and affective factors matter

    2016-01-01

    Understanding the forces that support and inhibit product development (PD) in family firms is central to explaining their long-term success and survival. Our study reveals that social capital and relational conflict among family members do not affect PD directly, as existing theory suggests, but only through the internalization of knowledge among family members. In contrast, family members’ affective commitment to the family firm is so powerful that it has both a mediated and a direct effect ...

    The present study aims to: (1) estimate the levels of internalizing symptoms and externalizing behaviors among youth affected by HIV in central Haiti; and (2) examine the risk and protective factors associated with these outcomes to identify potential areas of intervention for HIV-affected youth. Baseline data for 492 youth affected by HIV (ages 10-17) and their 330 caregivers were collected for a pilot study of a psychosocial support intervention. Participants were recruited from a list of HIV-positive patients receiving care at Partners In Health/Zanmi Lasante clinic sites. Internalizing and externalizing behaviors were assessed using the Strengths and Difficulties Questionnaire. Demographic, economic, and social indicators were collected using a structured questionnaire administered by trained social workers. Youth affected by HIV in central Haiti displayed high levels of internalizing and, to a lesser degree, externalizing symptoms. Multivariate regression analysis demonstrated risk factors most strongly associated with internalizing symptoms (socioeconomic status, parental depressive symptoms) and externalizing behaviors (household living arrangements, such as living with a stepparent). Social support had a protective effect on externalizing behaviors for both caregiver (β=-0.03, p=0.01) and self-report (β=-0.05, pHaiti and similar resource-limited settings.

    Identification of the sentinel lymph node (SLN) for small mammary tumours (cT1N0) sometimes leads to detection of internal mammary chain (IMC) drainage. This information is often ignored by physicians. The present study sought to determine the frequency with which an internal mammary SLN was identified by peritumoral injection of radioactive tracer, and then to determine the patients in whom identification of an internal mammary SLN could have an impact on the radiation treatment plan. Between March 2002 and March 2008, 622 SLN biopsies performed in a cohort of 608 patients were analysed. Technetium-labelled nanocolloids were administered via three peritumoral injections, completed by a deep prepectoral injection, with the entire procedure performed under echographic guidance. The SLN was identified in 607 of the 622 patients, including 174 (28.7%) in the IMC. A total of 161 successful internal mammary biopsies were performed. Of the 622 patients, 18 showed SLN involvement in the IMC. In 7 of these patients, only the internal mammary SLN was affected. Prophylactic irradiation of the IMC was indicated in 376 patients, but only in 18 (4.8%) of these patients was there effectively IMC involvement; internal mammary SLN biopsy failed in 7 patients (1.9%). SLN detection by peritumoral injection, combined with the systematic removal of the internal mammary SLN, enabled the involvement of this region to be found in a nonnegligible number of patients. Such information should make it possible to personalize treatment for patients with stage cT1 mammary cancer and thereby avoid needless internal mammary radiation therapy in a large number of patients (93.4% in our study).

    Research on the factors affecting progress in medical schools has typically focused on mainstream (non-Indigenous Australian, non-international) students in traditional, didactic programmes. These results may not be applicable to students, particularly those from culturally diverse backgrounds, undertaking problem-based learning courses. This study used qualitative methodology to explore and compare factors affecting progress for mainstream Australian students (non-Indigenous Australian, non-international) and international students (full fee-paying students who had relocated countries to study) in a problem-based learning medical course. Intervention strategies were devised on the basis of the participants' experiences. Six focus group discussions were conducted (three with mainstream Australian and three with international participants). Transcripts of these discussions were coded and analysed independently by two researchers and discussed until consensus was attained. Participants identified both positive and negative experiences related to the course structure, which were consistent with previous findings. The participants' experiences demonstrated a relationship between sense of 'belongingness' to the medical school community, participation in learning opportunities and progress through the course. The results suggest that interventions aimed at reducing barriers to progress need to promote students' confidence, motivation and subsequent participation in course learning opportunities. These results have application to other problem-based learning courses particularly those which face the challenge of providing an optimal learning environment for students from diverse backgrounds.

  14. Liposomal internal viscosity affects the fate of membrane deformation induced by hypertonic treatment.

    Fujiwara, Kei; Yanagisawa, Miho

    2017-12-13

    Artificial lipid membranes have been utilized to understand the physical mechanisms of the deformation patterns of live cells. However, typical artificial membrane systems contain only dilute components compared to those in the cytoplasm of live cells. By using giant unilamellar liposomes containing dense protein solutions similar to those in live cells, we here reveal that viscosity derived from internal crowding affects the deformation patterns of lipid membranes. After hypertonic treatment, liposome deformation patterns transitioned from budding to tubing when the initial internal macromolecular concentrations were increased. Remarkably, instead of observing different transition concentrations between two species of macromolecules, the viscosity at the transition concentration was found to be similar. Further analyses clearly demonstrated that the internal viscosity affects the deformation patterns of lipid membranes induced by hypertonic treatment. These results indicate that the viscosity of the cytoplasm is a key factor in determining cell deformation, and suggest the association of a process involving dynamic instability, such as a viscous fingering phenomenon, during the determination of deformation patterns by hypertonic treatment.

  15. Impaired picture recognition in transient epileptic amnesia.

    2015-01-01

    Transient epileptic amnesia (TEA) is an epileptic syndrome characterized by recurrent, brief episodes of amnesia. Transient epileptic amnesia is often associated with the rapid decline in recall of new information over hours to days (accelerated long-term forgetting - 'ALF'). It remains unknown how recognition memory is affected in TEA over time. Here, we report a systematic study of picture recognition in patients with TEA over the course of one week. Sixteen patients with TEA and 16 matched controls were presented with 300 photos of everyday life scenes. Yes/no picture recognition was tested 5min, 2.5h, 7.5h, 24h, and 1week after picture presentation using a subset of target pictures as well as similar and different foils. Picture recognition was impaired in the patient group at all test times, including the 5-minute test, but it declined normally over the course of 1week. This impairment was associated predominantly with an increased false alarm rate, especially for similar foils. High performance on a control test indicates that this impairment was not associated with perceptual or discrimination deficits. Our findings suggest that, at least in some TEA patients with ALF in verbal recall, picture recognition does not decline more rapidly than in controls over 1week. However, our findings of an early picture recognition deficit suggest that new visual memories are impoverished after minutes in TEA. This could be the result of deficient encoding or impaired early consolidation. The early picture recognition deficit observed could reflect either the early stages of the process that leads to ALF or a separable deficit of anterograde memory in TEA. Lastly, our study suggests that at least some patients with TEA are prone to falsely recognizing new everyday visual information that they have not in fact seen previously. This deficit, alongside their ALF in free recall, likely affects everyday memory performance. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Persons affected by migration require health systems that are responsive and adaptable to the needs of both disadvantaged migrants and non-migrant populations. The objective of this study is to support health systems for populations affected by migration. Materials and Methods: An international Delphi consensus process was used to identify policy approaches to improve health systems for populations affected by migration. Participants were leading migrant health experts from Americas, Europe, Middle East, Asia, and Australasia. We calculated average ranking scores and qualitatively analyzed open-ended questions. Results: Participants identified the following key areas as priorities for policy development: health inequities, system discrimination, migrant related health data, disadvantaged migrant sub-groups, and considerations for disadvantaged non-migrant populations. Highly ranked items to improve health systems were: Health Equity Impact Assessment, evidence based guidelines, and the International Organization for Migration annual reports. Discussion: Policy makers need tools, data and resources to address health systems challenges. Policies need to avoid preventable deaths of migrants and barriers to basic health services.

  18. Brucella abortus choloylglycine hydrolase affects cell envelope composition and host cell internalization.

    Directory of Open Access Journals (Sweden)

    María Inés Marchesini

    Full Text Available Choloylglycine hydrolase (CGH, E.C. 3.5.1.24 is a conjugated bile salt hydrolase that catalyses the hydrolysis of the amide bond in conjugated bile acids. Bile salt hydrolases are expressed by gastrointestinal bacteria, and they presumably decrease the toxicity of host's conjugated bile salts. Brucella species are the causative agents of brucellosis, a disease affecting livestock and humans. CGH confers Brucella the ability to deconjugate and resist the antimicrobial action of bile salts, contributing to the establishment of a successful infection through the oral route in mice. Additionally, cgh-deletion mutant was also attenuated in intraperitoneally inoculated mice, which suggests that CGH may play a role during systemic infection other than hydrolyzing conjugated bile acids. To understand the role CGH plays in B. abortus virulence, we infected phagocytic and epithelial cells with a cgh-deletion mutant (Δcgh and found that it is defective in the internalization process. This defect along with the increased resistance of Δcgh to the antimicrobial action of polymyxin B, prompted an analysis of the cell envelope of this mutant. Two-dimensional electrophoretic profiles of Δcgh cell envelope-associated proteins showed an altered expression of Omp2b and different members of the Omp25/31 family. These results were confirmed by Western blot analysis with monoclonal antibodies. Altogether, the results indicate that Brucella CGH not only participates in deconjugation of bile salts but also affects overall membrane composition and host cell internalization.

    2013-04-01

    Despite the importance given to employment opportunities as a primary motive for migration, previous studies have paid insufficient attention to the kinds of jobs that are more likely to retain workers in their countries of origin. We use information from a panel survey of Mexican adults to examine how job characteristics affect the risk of international migration. The sampling strategy and overall size of the survey allow us to analyze the effect of employment characteristics on migration from urban areas, which have much greater labor market diversity, and to separate our analysis by gender. We also distinguish migrants according to whether they migrate for work or for other reasons. We find informality to be a significant predictor of international migration. Even after controlling for individual factors including workers' wages, as well as various household- and community-level predictors, we find that workers employed in the informal sector have significantly higher odds of migrating than their counterparts in the formal sector. The pervasive nature of informality in many developing countries from which a high proportion of international migrants originate may therefore create a constant supply of workers who are predisposed to migrate. Our findings thus have important implications for a proper understanding of the effects of economic development on migration.

    The available picture sets in alcohol research are scarce and display a number of limitations, including poor picture quality, limited number of stimuli and absence of non-alcohol and/or real-life images. In the present study, we developed the Galician Beverage Picture Set (GBPS), a database of high-quality alcohol and non-alcohol pictures embedded in real-life scenarios. A total of 201 college students (∼59% females) were assessed by the Alcohol Use Disorders Identification Test, ∼54% being characterized as no/low drinkers (N/LDs) and ∼46% as risky drinkers (RDs). The GBPS included six types of beverages: beer, wine, liquor (alcoholic drinks); water, juice, milk (non-alcoholic drinks). Additionally, two subcategories were considered: orientation (landscape, portrait) and number of people (0, 1, ≥2 people). Participants rated the images for valence, arousal and visual complexity. Objective measures of brightness and color and recognition rates were also assessed. Internal consistency was estimated using Cronbach's alpha coefficient. There was a high degree of internal consistency within each category (alcoholic and non-alcoholic drinks) for valence, arousal and visual complexity scores. A mixed-model ANOVA revealed that RDs rated alcohol pictures as more pleasant and arousing than N/LDs. Conversely, N/LDs displayed greater valence and arousal ratings than RDs for non-alcohol pictures. The GBPS provides normative data on affective (valence/arousal), perceptual (visual complexity) and physical (brightness/color) values for a large number of images that may be useful for alcohol-related research. Differences in subjective assessments between N/LDs and RDs support the picture set's suitability for studies in young drinkers. Copyright © 2018 Elsevier B.V. All rights reserved.

    The aim of this systematic review is to analyze the effect of tibial rotational alignment after total knee arthroplasty (TKA) on clinical outcomes and assess the eventual cut-off values for tibial TKA rotation leading to poor outcomes. A detailed and systematic search from 1997 to 2017 of the Pubmed, Medline, Cochrane Reviews, and the Google Scholar databases was performed using the keyword terms "total knee arthroplasty", "total knee replacement", "tibial alignment", "tibial malalignement", "tibial rotation", "rotational error", "axis", "angle", "tibial malrotation", "clinical outcome", in several combinations. The modified Coleman scoring methodology (mCMS) was used. All the primary TKAs studies analyzing correlation between clinical results and tibial rotation were included. Five articles met the inclusion criteria. A total of 333 arthroplasties were included in this review; 139 had tibial component malalignment, while 194 were in control groups. The mean age of patients was 67.3 (SD 0.57) years. The mean average postoperative follow-up delay was 34.7 months (range 21-70). The mean mCMS score was 59.2 points indicating good methodological quality in the included studies. Functional outcomes were assessed through KSS, OKS, KOOS and VAS, negatively related to tibial internal rotation. Our review confirmed that excessive internal rotation of the tibial TKA component represents a significant risk factor for pain and inferior functional outcomes after TKA (> 10° of internal rotation demonstrated the common value), since external rotation does not affect the results. However, a universal precise cut-off value has not been found in the available literature and there remains a debate about CT rotation assessment and surgical intra-operative landmarks. III.

    1989-01-01

    The first part of the book describes the development of a polarised spectrum of attitudes towards science and technology over the last two decades. Positivistic attitudes that emerged from the materialistic branch of the period of Enlightenment are shown in contrast to the attitudes that stem from the philosophical line of Rousseau-romanticism-vitalism. The second part of the book presents the results of an empirical study, providing evidence for the existence of the different attitudes towards technology and the environment. The study is based on a representative opinion poll among civil servants, engineering professions, social workers, and artists. Engineers and social workers are shown to represent the two antipodes in terms of the 'dual-culture' theory. In addition, sex-specific and age-specific differences are explained, and the different pictures of technology drawn by personalities characterised by an attitude of active control in contrast to those characterised by an attitude of intuitive faith.

    This book presents a new and comprehensive theory concerning the manner in which landscapes in Western pictorial art may be interpreted in relation to the cultures that created them. Its point of departure is a hitherto unexplored developmental pattern that characterises landscape representation...... from Palaeolithic cave paintings through to 19th-century modernity. A structuralist comparison between this pattern and three additional fields of analysis - self-consciousness, socially-determined perception of nature, and world picture - reveals a fascinating insight into culture's macrohistorical...... organisation. Controversially, this book argues that culture at a certain level of observation is marked by a directional evolution. In Volume I the author traces the pictorial depth of field from its Palaeolithic beginnings, in which only separate bodies are portrayed, and on to antiquity and the Middle Ages...

    This paper describes two small-area selection schemes that the authors have applied to CCD observations of solar granulation. The first scheme, which the authors call the ''mosaic,'' divides the 128 x 128 array into 64 subarrays each containing 16 x 16 pixels. On each picture in the burst the RMS contrast of the fine structure is measured in each subarray and compared to the corresponding value in a table that contains the highest previous RMS values. The second scheme, which the authors call a ''collage,'' is similar except the RMS value is calculated smoothly within a sliding Gaussian window over the entire scene and the value of an individual pixel is gated into the final collage whenever the RMS contrast at that pixel location exceeds that of all previous frames taken during the burst

  9. External and Internal Barriers to Studying Can Affect Student Success and Retention in a Diverse Classroom

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Although a majority of under-represented minority (URM students begin their postsecondary education at community colleges, little is known about barriers to success and retention for transfer-bound science students. This study focuses on some of the barriers that affect these students’ ability to study adequately for a community college “gateway” course. It tests whether instructors’ expectations of study time were realistic for community college students and whether students reported facing external barriers, such as job and family responsibilities, or internal barriers to studying, such as lack of motivational, cognitive, and metacognitive abilities, all of which have been shown to impact academic success and retention. It also tests whether students who faced such barriers were less likely to succeed in and complete the course, as well as whether time spent studying was related to course success. The findings reported here show that community college students do not have enough available time to study and that external and internal barriers are both prevalent among these students. In addition, students who faced such barriers are more likely to fail or drop the class. Results also show that study time is positively correlated with retention, but not performance, as well as with some motivational, cognitive, and metacognitive dimensions of self-regulated learning. These findings lead to new questions, including whether student success in a community college class is associated with the use of cognitive and metacognitive learning strategies for students with no prior degrees, and whether increased course structure may improve success for college students with lower self-regulated abilities.

  10. International trends affecting the development of small and medium sized reactors

    Echavarri, L.

    2002-01-01

    The beginning of the 21st century is characterised by significant changes in the energy policy-making framework of most countries. Globalisation of the world economy, deregulation of electricity markets, privatisation of the electricity sector, increasing concerns about the need to protect the environment and awareness of sustainable development goals are among the major trends affecting policy making and decisions in the energy sector. All those factors have impacts on nuclear energy programmes and may affect SMR development in particular. The paper investigates how those factors may change national energy policies and impact on nuclear energy programmes, with special emphasis on the potential role of SMRs in energy supply mixes. It elaborates on recent trends to increasing reliance on market mechanisms in the energy and electricity sectors and on the role of governments in implementing an integrated approach to policy making, within a sustainable development framework incorporating economic, social and environmental dimensions. Against this backdrop, the paper examines the potential markets for SMRs, taking into account their possible uses beyond electricity generation, such as potable water production, cogeneration, process or domestic heat supply and eventually hydrogen production. It reviews key issues to be addressed in order to facilitate the deployment of SMRs in different countries. Those include technology progress and transfer, capacity building in developing countries, adaptation to market requirements, economic competitiveness and social acceptance. The paper concludes with remarks regarding the importance of international co-operation, especially in the field of research and development on advanced reactor and fuel cycle concepts. In this connection, the role of intergovernmental organisations as facilitators and catalysts of national efforts is highlighted. (author)

Furthermore, the IAQG seeks to understand the valuation of ISO/AS9100 requirements (2009), audit practices, management functions, business performance, customer satisfaction, and potential future concepts for the standard to assure quality. Since the release of the AS9100C total certification growth surpassed 1,100,000 organizations in 2010 with ISO 9001 series adoption and implementation governing business operations (ASQ, 2012b; ISO, 2011; Bernardo, Llach, & Marimon, 2011). Historians such as Crosby, Juran, Deming, and others established the foundation for quality assurance. Several researchers explored the issues which complicate overall benefits of ISO certification (Iwaro & Mwasha, 2012; Karthi et al., 2012; Sampaio et al., 2009). This study examined the effects on AS&D industries from ISO compliance to identify the implications (of ever-changing requirements) through an online survey of 15,000 practitioners. The research illuminated how ISO affects AS&D industries with current and future requirements for certification. The data showed that 75% of survey respondents report implementation of the AS9100C requirements still has benefits that outweigh the cost. Findings suggest that AS&D industries perceive significant value in the AS9100C document as part of the overall ISO 9000 series. In general, the comments from the survey can provide insight into the affects of ISO certification. The study concludes by recommending continued research to learn of further impacts from ISO certification within AS&D industries to improve the AS9100 document requirements for quality management systems.

  12. Matter - a current picture.

    Macrae, Roderick M

    2017-05-01

    A century ago, a two-part review by W. C. McC. Lewis entitled "The Structure of Matter" appeared in this journal, surveying the achievements that had been made to date in that field. Topics included the value of Avogadro's constant, the dimensions of a molecule, equations of state for non-ideal gases, then-current theories relating electron configurations to the Periodic Law, the then-new nuclear atom model of Rutherford, and the first findings from X-ray crystallographic studies of matter, a field then in its nascent phase. This article is a sequel to that work. As a vast quantity of research has been addressed to the topic in the intervening period, the view presented here can at best be selective and idiosyncratic. Nonetheless, it attempts to capture some of the important strides in 'matter science', broadly defined, over the past century, highlight some recent areas of interest or novelty, and give a picture of some of the mysteries that remain.

  13. Affective Policy Performance Evaluation Model: A Case of an International Trade Policy Implementation

    2018-01-01

    Full Text Available Firms often superficially adopt policies because of governmental rules and regulations, so as to avoid penalties or to gain benefits. However, the evaluation and characterization of those kinds of adoptions as policy performance distorts the true level of policy performance: social sustainability. This study proposes an affective policy performance evaluation model. The attitudes of employees toward adopting a policy are characterized into genuine and superficial compliance. Their behaviors are explained through voluntary and opportunistic adoptions. In order to validate the proposed model, a survey was conducted on an international trade policy target group (n = 216 for the Strategic Trade Control System (STCS, in order to understand their attitudes toward adopting the policy. The survey data was analyzed by a structural equation modeling method. The measures of the factors in the proposed model are adopted and modified from existing studies. The most effective resources of policy implementation on the firms’ genuine and superficial compliance and ultimately on the firms’ voluntary policy adoption are revealed through the analysis. Based on the results, this study presents a strategy for allocating and managing policy implementation resources to exclusively encourage firms’ trade policy adoptions.

    Most previous neurophysiological studies evoked emotions by presenting visual stimuli. Models of the emotion circuits in the brain have for the most part ignored emotions arising from musical stimuli. To our knowledge, this is the first emotion brain study which examined the influence of visual and musical stimuli on brain processing. Highly arousing pictures of the International Affective Picture System and classical musical excerpts were chosen to evoke the three basic emotions of happiness, sadness and fear. The emotional stimuli modalities were presented for 70 s either alone or combined (congruent) in a counterbalanced and random order. Electroencephalogram (EEG) Alpha-Power-Density, which is inversely related to neural electrical activity, in 30 scalp electrodes from 24 right-handed healthy female subjects, was recorded. In addition, heart rate (HR), skin conductance responses (SCR), respiration, temperature and psychometrical ratings were collected. Results showed that the experienced quality of the presented emotions was most accurate in the combined conditions, intermediate in the picture conditions and lowest in the sound conditions. Furthermore, both the psychometrical ratings and the physiological involvement measurements (SCR, HR, Respiration) were significantly increased in the combined and sound conditions compared to the picture conditions. Finally, repeated measures ANOVA revealed the largest Alpha-Power-Density for the sound conditions, intermediate for the picture conditions, and lowest for the combined conditions, indicating the strongest activation in the combined conditions in a distributed emotion and arousal network comprising frontal, temporal, parietal and occipital neural structures. Summing up, these findings demonstrate that music can markedly enhance the emotional experience evoked by affective pictures.

  18. Behavioral modulation by mutilation pictures in women

    2004-01-01

    Full Text Available Previous studies have shown that women are more emotionally expressive than men. It is unclear, however, if women are also more susceptible to the emotional modulation of behavior imposed by an affective stimulus. To investigate this issue, we devised a task in which female subjects performed six sequential trials of visual target detection following the presentation of emotional (mutilation and erotic or neutral pictures (domestic utensils and objects and compared the data obtained in the present study with those described in a previous study with male subjects. The experiment consisted of three blocks of 24 pictures and each block had an approximate duration of 4 min. Our sample consisted of 36 subjects (age range: 18 to 26 years and each subject performed all blocks. Trials following the presentation of mutilation pictures (283 ms had significantly slower reaction times than those following neutral (270 ms pictures. None of the trials in the "pleasant block" (271 ms was significantly different from those in the "neutral block". The increase in reaction time observed in the unpleasant block may be related in part to the activation of motivational systems leading to an avoidance behavior. The interference effect observed in this study was similar to the pattern previously described for men. Thus, although women may be more emotionally expressive, they were not more reactive to aversive stimuli than men, as measured by emotional interference in a simple reaction time task.

    2014-01-01

    The theoretical model proposed by Berry and colleagues (Berry, 1997; Berry, Kim, Minde, & Mok, 1987) highlights the importance of identifying moderators in the acculturation process. Accordingly, the current study examined the Asian cultural value of family recognition through achievement (FRTA) and contingency of self-worth on academic competence (CSW-AC) as moderators in the association between academic stress and positive affect among Chinese international students. A total of 370 Chinese international students completed online surveys. Results from a hierarchical regression indicated that while academic stress was negatively associated with positive affect, FRTA was positively associated with positive affect. In other words, those with high academic stress reported a lower level of positive affect. However, individuals who endorsed high levels of FRTA reported a higher level of positive affect. In addition, results also revealed a significant interaction between academic stress and CSW-AC on positive affect. Thus, the study's finding supported the moderator role of CSW-AC. Simple effect analyses were conducted to examine the significant interaction. The results showed that higher levels of CSW-AC strengthened the negative association between academic stress and positive affect but lower levels of CSW-AC did not. Future research directions and implications are discussed.

    Energy is essential for development. Nearly every aspect of development - from reducing poverty to improving health-care requires reliable access to modern energy services. When these developments needs remain unaddressed, the resulting misery often leads to conflict and violence, which in turn affect development efforts and impact on regional and global stability. In this context, it is important to consider the global energy imbalance. Naturally, nuclear energy alone is not a panacea, but it is likely in the near future to have an increasing role as part of the global energy mix

  4. Perceptual representations in false recognition and priming of pictures.

    Science.gov (United States)

    Weinstein, Yana; Shanks, David R

    2008-12-01

    Using a new procedure, we investigate whether imagination can induce false memory by creating a perceptual representation. Participants studied pictures and words with and without an imagery task and at test performed both a direct recognition test and an indirect perceptual identification test on pictorial stimuli. Corrected false recognition rates were 7% for pictures studied in word form (Experiment 1), 26% for pictures imagined once (Experiment 2), and 48% for pictures imagined multiple times (Experiment 3), although on the indirect test, no priming was found for these items. Furthermore, a perceptual/conceptual imagery manipulation did not affect the tendency to claim that imagined items had been studied as pictures (Experiment 4). These results suggest that the false memories reported on direct tests are not driven by perceptual representations.

    2013-10-01

    The study examines the relationship between internalization of stigma, self-esteem, and the ability of people diagnosed with schizophrenia to form intimate attachments with loved ones. The study included sixty patients with schizophrenia, ages 18-60, men and women. After providing informed consent, all participants completed four questionnaires: Demographics Questionnaire, Self-Esteem Scale, Internalized Stigma of Mental Illness Scale and the Intimacy Attitude Scale-Revised. Internalization of social stigma was found to be a statistically significant core factor that affects self-esteem and the ability to create intimacy among patients with schizophrenia. There was statistically significantly less internalization of stigma of mental illness among hospitalized patients than among individuals with schizophrenia who live in the community.

    2011-03-01

    The aim of this study was to examine the direction and the etiology of the association between different parenting styles (parental emotional overinvolvement [EOI] and parental criticism) and internalizing behavior from adolescence to early adulthood. A longitudinal genetically informative cross-lagged design was applied to a population-based sample of Swedish twins contacted at age 16-17 (n = 2369) and at age 19-20 (n = 1705). Sex-limitation modelling revealed different effects for boys and girls. For girls, genetic influences on internalizing problems at age 16-17 independently explained 2.7% of the heritability in parental EOI at age 19-20. These results suggest that emotionally overinvolved and self-sacrificing parental behavior stems in part from daughters (but not sons) genetic predisposition for internalizing behavior. These findings highlight the importance of genetically influenced child-driven effects underlying the parenting-internalizing association, and clarify that the role of such effects may differ depending on sex, type of parenting and developmental period.

    Older adults' relatively better memory for positive over negative material (positivity effect) has been widely observed in Western samples. This study examined whether a relative preference for positive over negative material is also observed in older Koreans. Younger and older Korean participants viewed images from the International Affective Picture System (IAPS), were tested for recall and recognition of the images, and rated the images for valence. Cultural differences in the valence ratings of images emerged. Once considered, the relative preference for positive over negative material in memory observed in older Koreans was indistinguishable from that observed previously in older Americans.

The development of deep reading is differentiated from the acquisition of functional literacy skills. Further, the differentiation between the medium-embeddedness of pictures and the perceptual-transactional and culturally shaped nature of images is highlighted with regard to the affordances of pictures in picturebooks and graphic novels. In some children’s literature, the opportunities for meaningful booktalk are amplified by an apparently simple style of illustration. This process has been termed amplification through simplification, which, in contrast to simplifying by stereotyping, can help lead to intercultural understanding and deep reading. The affordances of pictures in supporting young adult readers to create a mental model of a storyworld is discussed with reference to two panels from Coraline (Gaiman & Russell, 2008, a graphic novel.

    There is evidence that besides limbic brain structures, prefrontal and insular cortical activations and deactivations are involved in the pathophysiology of panic disorder. This study investigated activation response patterns to stimulation with individually selected panic-specific pictures in patients with panic disorder with agoraphobia (PDA) and healthy control subjects using functional magnetic resonance imaging (fMRI). Structures of interest were the prefrontal, cingulate, and insular cortex, and the amygdalo-hippocampal complex. Nineteen PDA subjects (10 females, 9 males) and 21 healthy matched controls were investigated using a Siemens 3-Tesla scanner. First, PDA subjects gave Self-Assessment Manikin (SAM) ratings on 120 pictures showing characteristic panic/agoraphobia situations, of which 20 pictures with the individually highest SAM ratings were selected. Twenty matched pictures showing aversive but not panic-specific stimuli and 80 neutral pictures from the International Affective Picture System were chosen for each subject as controls. Each picture was shown twice in each of four subsequent blocks. Anxiety and depression ratings were recorded before and after the experiment. Group comparisons revealed a significantly greater activation in PDA patients than control subjects in the insular cortices, left inferior frontal gyrus, dorsomedial prefrontal cortex, the left hippocampal formation, and left caudatum, when PA and N responses were compared. Comparisons for stimulation with unspecific aversive pictures showed activation of similar brain regions in both groups. Results indicate region-specific activations to panic-specific picture stimulation in PDA patients. They also imply dysfunctionality in the processing of interoceptive cues in PDA and the regulation of negative emotionality. Therefore, differences in the functional networks between PDA patients and control subjects should be further investigated.

    Submarine canyons are major conduits of terrestrial and shelf organic matter, potentially benefiting the seafloor communities in the food-deprived deep sea; however, strong bottom currents driven by internal tides and the potentially frequent turbidity currents triggered by storm surges, river flooding, and earthquakes may negatively impact the benthos. In this study, we investigated the upper Gaoping Submarine Canyon (GPSC), a high-sediment-yield canyon connected to a small mountain river (SMR) off southwest (SW) Taiwan. By contrasting the benthic meiofaunal and macrofaunal communities within and outside the GPSC, we examined how food supplies and disturbance influenced the benthic community assemblages. The benthic communities in the upper GPSC were mainly a nested subset of the adjacent slope assemblages. Several meiofaunal (e.g. ostracods) and macrofaunal taxa (e.g. peracarid crustaceans and mollusks) that typically occurred on the slope were lost from the canyon. The polychaete families switched from diverse feeding guilds on the slope to motile subsurface deposit feeders dominant in the canyon. The diminishing of epibenthic peracarids and proliferation of deep burrowing polychaetes in the GPSC resulted in macrofauna occurring largely within deeper sediment horizons in the canyon than on the slope. The densities and numbers of taxa were depressed with distinct and more variable composition in the canyon than on the adjacent slope. Both the densities and numbers of taxa were negatively influenced by internal tide flushing and positively influenced by food availability; however, the internal tides also negatively influenced the food supplies. While the meiofauna and macrofauna densities were both depressed by the extreme physical conditions in the GPSC, only the macrofaunal densities increased with depth in the canyon, presumably related to increased frequency and intensity of disturbance toward the canyon head. The population densities of meiofauna, on the

Based on the World Economic Forum (WEF report on global risks 2015-2017, the impact of global risks on the social and economic development of countries is examined. Economic, social, environmental, geopolitical, technological risks are analyzed in a coordinated fashion. The article notes that the main risks are in the field of environment and ecology. Anthropogenic pressure amplification, scientific and technological advance have an influence on the natural environment. The risks of infrastructure and environmental damage in danger zone are increased because of the growth of the frequency of extreme weather events. The measures for the protection of the environment are examined. The unilateral approach to solving international issues, instead of the collective efforts of the international community; the deployment of weapons of mass destruction (nuclear, chemical, biological and technologies for the production of radioactive materials; escalation of economic and resource nationalization (the desire of States to expropriate or restrict the export of important for the world economy of resources, etc. promote the increasing geopolitical risks.Economic risks include the risk in terms of their likelihood their impact on the macroeconomic, as from the financial systems and infrastructure to price volatility and regulatory issues. Social risks are the risks relating to instability of population dynamics, social crises and human survival.Technological risks include such problems as software defects, failure of important information systems, upon which today industrial production is depended, the services and communications sector; the escalation of large-scale cyber-attacks; theft of electronic information and the illegal usage of personal data. The trends that can intensify the global risks or to change the correlation between them are analyzed in this article.

    2016-01-01

    Full Text Available The aim of the paper is to point to two fundamentally different strategies of painting practice, that is, to two subsystems of painting: picture and painting. This differentiation can be made within the framework of semiotic and semiological analyses which have developed in theory under the influence of structuralism. The first part of the paper offers a basic insight into the linguistic foundation of structuralistic concept, and then sets a thesis about the possibility of analogue reconceptualisation of semiotics/semiology of painting through Julia Kristeva's semiotics and Roland Barthes' semiology. In addition, it points to the concrete concepts of structural analysis which have accentuated the opposition picture-painting with the examples of art practice concurrent to the development of structuralism. However, what is revealed is that various structuralist readings are significantly subjective to unstable relationship between the basic elements in the pictorial object, that is, in the work of painting.

  13. Fluoroangiographic picture of chorioretinal folds

    1988-01-01

    Fluoroangiographic pictures of chorioretinal folds (CRF) were analyzed in 13 eyes of 12 patients. The orbital origin of CRF was present in 8 eyes (orbital tumors in 7 eyes and thyroid ophthalmopathy in one eye), the intraocular origin in 5 eyes (hypotonic postoperative syndrome caused by the detachment of the choroid in 3 eyes, Irwine-Gass syndrome in 2 eyes, scleral bucle used for retinal detachment repair in one eye). The fluoroangiographic findings of CRF were determined by changes in the pigmented epithelium and choroid of a different degree, which modified the clinical picture of the basic disease. Fluorescein angiography is a very useful method for the differentiation of retinal and choroid detachments but with a limited possibility to determine the etiological factor of the disease.

  18. International risk factors affecting Finnish energy supplies. Suomen energiahuollon kansainvaeliset uhkatekijaet

    Kasanen, P.; Koponen, M.; Kaekoenen, J. (Oulu Univ., Oulu (Finland). Dept. of Geography)

    1989-01-01

    An examination is made of the structure and development of Finnish fuel imports, world fuel market trends and prospects, and the impact of global environmental concerns on Finnish energy supplies. Attention is focused on the political and economic developments to be expected in the major fuel producing or consuming countries. The aim is to look for factors that could treaten the functioning of Finnish fuel supplies and to suggest ways to avoid or overcome these threats. The research is based on Finnish and international energy statistics, published forecasts for the development of the fuel trade and fuel resources and the latest literature on energy economics and political science. Finland is heavily dependent on foreign fuels, over two thirds of her fuels supply being imported. By far the most important source of imports is the Soviet Union, although Poland is a major supplier of coal. The increase in domestic demands for fuels in these countries, will make it necessary for Finland to diversify the sources of her fuel imports. The suggestions made here include the following: Saudi-Arabia and Kuwait should be considered as possible new sources of oil. Coal could be imported from South Africa, provided that the apartheid policy is discontinued. Norway could provide some natural gas, although a Nordic pipeline system would be needed for this to be possible. Finland should invest in fuel resource exploration and development and in building the necessary infrastructure in the producing countries in order to improve the possibilities for reaching long-term agreements on fuel imports. Imporovements in the effiency of the end users of energy and an increase in the proportion of renewable sources of energy would not only be steps towards a sustainable fuel economy, but would also reduce the country's dependence on imported fuels.

    This study was conducted to evaluate the effects of various protein sources (soybean meal, SBM; cottonseed protein, CSP; double-zero rapeseed meal, DRM) on the internal quality of refrigerated eggs. A total of 360 laying hens (32 wk of age) were randomly allotted to six treatment groups (five replicates per treatment) and fed diets containing SBM, CSP, or DRM individually or in combination with equal crude protein content (SBM-CSP, SBM-DRM, and CSP-DRM) as the protein ingredient(s). A 6×3 factorial arrangement was employed with dietary types and storage time (0 d, 2 wk, and 4 wk) as the main effects. After 12 wk of diet feeding, a total of 270 eggs were collected for egg quality determination. The egg Haugh unit (HU) in the CSP, SBM-DRM, and DRM groups were significantly lower than those in the SBM and SBM-CSP groups. The hardness and springiness of the cooked yolk in the CSP group were significantly higher than those in the other treatment groups. A lower HU, lower yolk index and higher albumen pH were observed in the DRM group compared to the SBM and SBM-CSP groups when the eggs were stored to 4 wk, and the HU was improved in the CSP-DRM group compared to the DRM group (pDRM groups showed no difference in comparison to the SBM group. In conclusion, CSP may ameliorate the negative effects of DRM on the HU of refrigerated eggs, and SBM or DRM may alleviate the adverse effects of CSP on yolk hardness.

    The water quality in Meiliang Bay of the Taihu Lake was totally tested five times in the four seasons. The suspension samples were obtained by using a sediment trap. The sediment settling flux and resuspended flux were calculated according to the observation data by using Gansith formula, and the relationships between these fluxes and wind speeds were established. Seven experiments were conducted in Laboratory for hydrostatic settling behavior of suspended matter affected by different wind speeds in Lake Taihu. The hydrostatic settling fluxes of suspended matter were calculated and the relationships between the fluxes and suspended matter concentrations were established. Base on these works, the suspension-sedimentation process was decomposed and generalized according to the critical wind speed of 3.7 m/s. Daily sediment resuspended amount and settling amount of the year 2005 was calculated and annual average release amount of internal load in Lake Taihu was estimated using the wind data of nearly 10 years. The results indicate that daily release amount of internal load in Lake Taihu significantly influenced by wind and have the same trend of change with wind, while the release amount of different nutrients in the same condition are different. The Lake Taihu has an annual average release amount of internal load with COD 49,600 t, TN 7773.0 t and TP 275.5 t, of which summer has the markedly highest release amount than other seasons.

  1. Low-level internalization of cystatin E/M affects legumain activity and migration of melanoma cells.

    The ratio between proteases and their inhibitors is unbalanced in cancer. The cysteine protease inhibitor cystatin C is internalized by some cancer cells, which affects cellular properties. Here we aimed to investigate if uptake of cystatin C and the related inhibitor cystatin E/M occur in melanoma cell lines and to evaluate to what extent the uptake affects the legumain activity that is typically increased in melanoma. First we studied the basic expression, secretion, and intracellular content of all type 2 cystatins as well as expression and activity of their possible target enzymes legumain and cathepsin B in MDA-MB-435S, A375, and C8161 melanoma cells. Legumain activity was measureable in all cell lines, and of the potential legumain inhibitors, cystatin C, E/M, and F, cystatin C was the one mainly produced. All cells internalized cystatin C added to culture media, leading to increased intracellular cystatin C levels by 120-200%. Cystatin E/M was internalized as well but at a modest rate. The effects on intracellular legumain activity were nevertheless pronounced, probably because the cells lacked this inhibitor, and its affinity for legumain is 100-fold higher than that of cystatin C. Likewise, the low-degree uptake resulted in reduced migration and invasion of A375 cells in Matrigel to an extent comparable with the W106F variant of cystatin C with optimal uptake properties and resulting in much higher intracellular levels. Thus, cystatin E/M appears to be a good candidate to efficiently down-regulate the increased legumain activity, possibly important for the malignant phenotype of melanoma cells. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

  2. Release of alkali salts and coal volatiles affecting internal components in fluidized bed combustion systems

    Arias del Campo, E.

    2003-12-01

    Full Text Available In spite of the potential advantages of atmospheric fluidized bed systems, experience has proved that, under certain environments and operating conditions, a given material employed for internal components could lead to catastrophic events. In this study, an attempt is made to establish material selection and operational criteria that optimize performance and availability based on theoretical considerations of the bed hydrodynamics, thermodynamics and combustion process. The theoretical results may indicate that, for high-volatile coals with particle diameters (dc of 1-3 mm and sand particle size (ds of 0.674 mm, a considerable proportion of alkali chlorides may be transferred into the freeboard region of fluidized bed combustors as vapor phase, at bed temperatures (Tb < 840 °C, excess air (XSA ≤ 20 %, static bed height (Hs ≤ 0.2 m and fluidizing velocity (Uo < 1 m/s. Under these operating conditions, a high alkali deposition may be expected to occur in heat exchange tubes located above the bed. Conversely, when the combustors operate at Tb > 890 °C and XSA > 30 %, a high oxidation rate of the in-bed tubes may be present. Nevertheless, for these higher Tb values and XSA < 10 %, corrosion attack of metallic components, via sulfidation, would occur since the excessive gas-phase combustion within the bed induced a local oxygen depletion.

    2007-03-01

    The present study combined the Independent Component Analysis (ICA) and low-resolution brain electromagnetic tomography (LORETA) algorithms to identify the spatial distribution and time course of single-trial EEG record differences between neural responses to emotional stimuli vs. the neutral. Single-trial multichannel (129-sensor) EEG records were collected from 21 healthy, right-handed subjects viewing the emotion emotional (pleasant/unpleasant) and neutral pictures selected from International Affective Picture System (IAPS). For each subject, the single-trial EEG records of each emotional pictures were concatenated with the neutral, and a three-step analysis was applied to each of them in the same way. First, the ICA was performed to decompose each concatenated single-trial EEG records into temporally independent and spatially fixed components, namely independent components (ICs). The IC associated with artifacts were isolated. Second, the clustering analysis classified, across subjects, the temporally and spatially similar ICs into the same clusters, in which nonparametric permutation test for Global Field Power (GFP) of IC projection scalp maps identified significantly different temporal segments of each emotional condition vs. neutral. Third, the brain regions accounted for those significant segments were localized spatially with LORETA analysis. In each cluster, a voxel-by-voxel randomization test identified significantly different brain regions between each emotional condition vs. the neutral. Compared to the neutral, both emotional pictures elicited activation in the visual, temporal, ventromedial and dorsomedial prefrontal cortex and anterior cingulated gyrus. In addition, the pleasant pictures activated the left middle prefrontal cortex and the posterior precuneus, while the unpleasant pictures activated the right orbitofrontal cortex, posterior cingulated gyrus and somatosensory region. Our results were well consistent with other functional imaging

  7. The role of pictures in improving health communication: a review of research on attention, comprehension, recall, and adherence.

    2006-05-01

    To assess the effects of pictures on health communications. Peer reviewed studies in health education, psychology, education, and marketing journals were reviewed. There was no limit placed on the time periods searched. Pictures closely linked to written or spoken text can, when compared to text alone, markedly increase attention to and recall of health education information. Pictures can also improve comprehension when they show relationships among ideas or when they show spatial relationships. Pictures can change adherence to health instructions, but emotional response to pictures affects whether they increase or decrease target behaviors. All patients can benefit, but patients with low literacy skills are especially likely to benefit. Patients with very low literacy skills can be helped by spoken directions plus pictures to take home as reminders or by pictures plus very simply worded captions. Educators should: (1) ask "how can I use pictures to support key points?", (2) minimize distracting details in pictures, (3) use simple language in conjunction with pictures, (4) closely link pictures to text and/or captions, (5) include people from the intended audience in designing pictures, (6) have health professionals plan the pictures, not artists, and (7) evaluate pictures' effects by comparing response to materials with and without pictures.

    2007-09-01

    The purpose of the present study was to compare the predictive effects of acculturative stressor and meaning of life on negative affect in the process of acculturation between Chinese international students in Australia and Hong Kong. Four hundred mainland Chinese students studying at six universities in Hong Kong and 227 Chinese international students studying at the University of Melbourne in Australia completed a questionnaire that included measures of acculturative stressor, meaning of life, negative affect and demographic information. The Australian sample was found to have a higher level of acculturative stressor and negative affect than the Hong Kong sample. Acculturative stressor had a positive impact on negative affect in both samples, but the impact of different domains of acculturative stressor on negative affect varied between the two groups. Finally, meaning of life partially mediated the relationship between acculturative stressor and negative affect in the Hong Kong sample, but no such effect was found in the Australia sample. Acculturative stressor is a critical risk factor for negative affect in acculturation for Chinese international students in Australia and Hong Kong. Meaning of life acted as a protective factor that mitigated negative affect for mainland Chinese students in Hong Kong, but not for the Chinese international students in Australia. The theoretical and practical implications for resilience-based and meaning-oriented intervention for Chinese international students are discussed.

  15. How do international trade obligations affect policy options for obesity prevention? Lessons from recent developments in trade and tobacco control.

    Science.gov (United States)

    von Tigerstrom, Barbara

    2013-06-01

    Regulatory measures, including taxes and subsidies on food and beverage products, food labelling requirements, regulation of food content and regulation of food marketing, have been proposed to encourage healthier eating and prevent obesity. The objective of this article is to explore the extent to which international trade agreements affect governments' choices to use such regulatory measures. It reviews key provisions of relevant World Trade Organization (WTO) agreements and their implications. Some insights can be gained by examining 2 recent developments in the WTO regarding tobacco control: a current dispute involving Australia's plain packaging law and its effect on trademarks, and a recent decision involving the United States law banning flavoured cigarettes. This decision said that the ban did not restrict trade more than necessary to fulfil its legitimate health objective, but it was discriminatory because it banned imported products (clove cigarettes) while exempting domestic products (menthol cigarettes) with similar characteristics. The conclusion we can draw from this decision is that WTO member states probably enjoy a significant degree of latitude in developing food regulations as part of an obesity prevention strategy, so long as those do not disproportionately affect imported products and therefore raise questions of discrimination. The approach taken in this case encourages the adoption of public health policies that are consistent with strong scientific evidence, but may restrict governments' ability to make political compromises, which could frustrate some proposals. The ongoing development of WTO law will continue to affect policy choices in public health. Copyright © 2013 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

    There are few studies comparing cross-cultural adaptation of migrant groups in two different cultural settings. This study compares the level of negative affect and acculturative stressors between Chinese international students in Australia and Mainland Chinese students in Hong Kong. The predictive effects of acculturative stressors and acculturative strategies on negative affect were also compared between the two groups. A total of 606 graduate students were recruited for a cross-sectional survey in Melbourne, and Hong Kong, China. The measurement included the Acculturative Hassles Scale for Chinese Students, Acculturative Strategy Scale, and Chinese Affect Scale. Independent t-tests and hierarchical regression analysis were conducted for data analysis. Chinese international students in Australia were found to encounter more acculturative stressors and experience a higher level of negative affect than their counterparts in Hong Kong. The acculturative stressor of academic work and a marginalization strategy significantly predicted negative affect in both groups. The acculturative stressor of cultural difference predicted negative affect in the Hong Kong sample, and assimilation strategy predicted negative affect in the Australian sample only. It is more difficult for Chinese international students to adapt to a host society with greater cultural distance. Cross-cultural comparative study helps to find out culture-general and culture-specific predictors of acculturation and helps design tailor-made intervention programs for international students across cultures.

    In prior work on how true and false memory are influenced by emotion, valence and arousal have often been conflated. Thus, it is difficult to say which specific effects are due to valence and which are due to arousal. In the present research, we used a picture-memory paradigm that allowed emotional valence to be manipulated with arousal held constant. Negatively-valenced pictures elevated both true and false memory, relative to positive and neutral pictures. Conjoint recognition modeling reve...

    The purpose of this study was to develop an auditory emotion recognition function that could determine the emotion caused by sounds coming from the environment in our daily life. For this purpose, sound stimuli from the International Affective Digitized Sounds (IADS-2), a standardized database of sounds intended to evoke emotion, were selected, and four psychoacoustic parameters (i.e., loudness, sharpness, roughness, and fluctuation strength) were extracted from the sounds. Also, by using an emotion adjective scale, 140 college students were tested to measure three basic emotions (happiness, sadness, and negativity). From this discriminant analysis to predict basic emotions from the psychoacoustic parameters of sound, a discriminant function with overall discriminant accuracy of 88.9% was produced from training data. In order to validate the discriminant function, the same four psychoacoustic parameters were extracted from 46 sound stimuli collected from another database and substituted into the discriminant function. The results showed that an overall discriminant accuracy of 63.04% was confirmed. Our findings provide the possibility that daily-life sounds, beyond voice and music, can be used in a human-machine interface.

    Full Text Available Background and Aims: Internal derangement of the Temporomandibular joint (TMJ is the most common form of Temporomandibular disorders, which represents an abnormal internal strucural and functional change of the disk, as well as an abnormal relationship of the disk to the condyle, glenoid fossa and articular eminence when the teeth are in the closed- mouth position. The aim of this study was to evaluate the correlation between eminence steepness and condyle disk movements in TMJs affected by internal derangements using magnetic resonance imaging (MRI. Materials and Methods: In this cross-sectional study, digital MRI files of 90 joints belong to 45 patients in open and closed-mouth positions were evaluated. Patients were subdivided into two groups: 64 individuals with anterior diskdisplacement with reduction and 26 individuals with anterior disk displacement without reduction. Appropriate oblique sagittal sections were selected and printed. Outlines of the fossa, eminence, condyle and disk were traced on matte acetate sheets and evaluated by an oral and maxillofacial radiologist and a postgraduate student of oral and maxillofacial radiology. Disk rotation, condyle rotation, condyle translation and eminence steepness were measured.The data were analyzed using T-test.Results: In this study, no significant difference was found in measurements between the two groups, (for steepness P=0.64, for Disc rotation P=0.77, for condyle rotation P=0.28 and for condyle translation P=0.12. Disk rotation showed statistically significant correlation with eminence steepness in the anterior disk displacement with reduction group 34 .Although this correlation was weak (r=0.27 (P>0.05. No statistically significant correlations were found between other variables and eminence steepness in this group (for condyle rotation P=0.3 and for condyle translation P=0.98. Disk rotation and condyle translation had statistically significant relationship in the anterior disk

    Background Alcohol cues can bias attention and elicit emotional reactions, especially in drinkers. Yet, little is known about how alcohol cues affect explicit and implicit memory processes, and how memory for alcohol cues is affected by acute alcohol intoxication. Methods Young adult participants (N=161) were randomly assigned to alcohol, placebo, or control beverage conditions. Following beverage consumption, they were shown neutral, emotional and alcohol-related pictures cues. Participants then completed free recall and repetition priming tasks to test explicit and implicit memory, respectively, for picture cues. Average blood alcohol concentration for the alcohol group was 74 ± 13 mg/dl when memory testing began. Two mixed linear model analyses were conducted to examine the effects of beverage condition, picture cue type, and their interaction on explicit and implicit memory. Results Picture cue type and beverage condition each significantly affected explicit recall of picture cues, whereas only picture cue type significantly influenced repetition priming. Individuals in the alcohol condition recalled significantly fewer pictures than those in other conditions, regardless of cue type. Both free recall and repetition priming were greater for emotional and alcohol-related cues compared to neutral picture cues. No interaction effects were detected. Conclusions Young adult drinkers showed enhanced explicit and implicit memory processing of alcohol cues compared to emotionally neutral cues. This enhanced processing for alcohol cues was on par with that seen for positive emotional cues. Acute alcohol intoxication did not alter this preferential memory processing for alcohol cues over neutral cues. PMID:26811126

    2015-05-01

    Full Text Available Background: Airport workers are continuously exposed to different levels of radiofrequency microwave (RF/MW radiation emitted by radar equipments. Radars are extensively used in military and aviation industries. Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons and MRI. The main goal of this study was to investigate if occupational exposure of Shahid Dastghieb international airport workers to radiofrequency radiation affects their short term memory and reaction time. Methods: Thirty two airport workers involved in duties at control and approach tower (21 males and 11 females, with the age range of 27-67 years old (mean age of 37.38, participated voluntary in this study. On the other hand, 29 workers (13 males, and 16 females whose offices were in the city with no exposure history to radar systems were also participated in this study as the control group. The employees’ reaction time and short term memory were analyzed using a standard visual reaction time (VRT test software and the modified Wechsler memory scale test, respectively. Results: The mean± SD values for the reaction times of the airport employees (N=32 and the control group (N=29 were 0.45±0.12 sec and 0.46±0.17 sec, respectively. Moreover, in the four subset tests; i.e. paired words, forward digit span, backward digit span and word recognition, the following points were obtained for the airport employees and the control group, respectively: (i pair words test: 28.00±13.13 and 32.07±11.65, (ii forward digit span: 8.38±1.40 and 9.03±1.32, (iii backward digit span: 5.54±1.87 and 6.31±1.46, and (iv word recognition: 5.73±2.36 and 6.50±1.93.

    Weinstein, Yana; Shanks, David R

    2010-07-01

    Recognition of pictures is typically extremely accurate, and it is thus unclear whether the reconstructive nature of memory can yield substantial false recognition of highly individuated stimuli. A procedure for the rapid induction of false memories for distinctive colour photographs is proposed. Participants studied a set of object pictures followed by a list of words naming those objects, but embedded in the list were names of unseen objects. When subsequently shown full colour pictures of these unseen objects, participants consistently claimed that they had seen them, while discriminating with high accuracy between studied pictures and new pictures whose names did not appear in the misleading word list. These false memories can be reported with high confidence as well as the feeling of recollection. This new procedure allows the investigation of factors that influence false memory reports with ecologically valid stimuli and of the similarities and differences between true and false memories.

  17. How do how internal and external processes affect the behaviors of coupled marsh mudflat systems; infill, stabilize, retreat, or drown?

    Intertidal coastal environments are prone to changes induced by sea level rise, increases in storminess, and anthropogenic disturbances. It is unclear how changes in external drivers may affect the dynamics of low energy coastal environments because their response is non-linear, and characterized by many thresholds and discontinuities. As such, process-based modeling of the ecogeomorphic processes underlying the dynamics of these ecosystems is useful, not only to predict their change through time, but also to generate new hypotheses and research questions. Here, a three-point dynamic model was developed to investigate how internal and external processes affect the behavior of coupled marsh mudflat systems. The model directly incorporates ecogeomorphological feedbacks between wind waves, salt marsh vegetation, allochthonous sediment loading, tidal flat vegetation and sea level rise. The model was applied to examine potential trajectories of salt marshes on the Eastern seaboard of the United States, including those in the Plum Island Ecosystems (PIE), Virginia Coast Reserve (VCR) and Georgia Coastal Ecosystems (GCE) long term ecological research (LTER) sites. While these sites are undergoing similar rates of relative sea level rise (RSLR), they have distinct differences in site specific environmental drivers including tides, wind waves, allochthonous sediment supply and the presence or absence of seagrass. These differences lead to the emergence of altered behaviors in the coupled salt marsh-tidal flat system. For marsh systems without seagrass or significant riverine sediment supply, conditions similar to those at PIE, results indicated that horizontal and vertical marsh evolution respond in opposing ways to wave induced processes. Marsh horizontal retreat is triggered by large mudflats and strong winds, whereas small mudflats and weak winds reduce the sediment supply to the salt marsh, decreasing its capability to keep pace with sea level rise. Marsh expansion and

    Many women have doubts about the normality of the physical appearance of their vulvas. This study measured genital self-image in a convenience sample of college-educated women, and assessed whether exposure to pictures of natural vulvas influenced their genital self-image. Forty-three women were either shown pictures of natural vulvas (N = 29) or pictures of neutral objects (N = 14). Genital self-image was measured before and after exposure to the pictures and two weeks later. Sexual function, sexual distress, self-esteem and trait anxiety were measured to investigate whether these factors influenced genital self-image scores after vulva picture exposure. A majority of the participants felt generally positively about their genitals. Having been exposed to pictures of natural vulvas resulted in an even more positive genital self-image, irrespective of levels of sexual function, sexual distress, self-esteem and trait anxiety. In the women who had seen the vulva pictures, the positive effect on genital self-image was still present after two weeks. The results of this study seem to indicate that even in young women with a relatively positive genital self-image, exposure to pictures of a large variety of natural vulvas positively affects genital self-image. This finding may suggest that exposure to pictures of natural vulvas may also lead to a more positive genital self-image in women who consider labiaplasty.

  19. Not just scenery: viewing nature pictures improves executive attention in older adults.

    Gamble, Katherine R; Howard, James H; Howard, Darlene V

    2014-01-01

    BACKGROUND/STUDY CONTEXT: Attention Restoration Theory (Kaplan, 1995, Journal of Environmental Psychology, 15, 169-182) suggests that exposure to nature improves attention. Berman, Jonides, and Kaplan (2008, Psychological Science, 19, 1207-1212) showed that simply viewing nature pictures improves executive attention in young adults. The present study is the first to investigate this Nature Effect in older adults. The authors investigated whether executive attention could be improved in healthy older adults following brief exposure to nature pictures. Thirty healthy older adults (64-79 years old) and 26 young university students (18-25 years old) participated. They completed the Attention Network Test before and after 6 min of viewing either nature or urban pictures, with random assignment into a picture type. Attention immediately before (most fatigued) and after (most restored) picture viewing was measured, and change in attention was compared between age groups and picture types. Results showed that viewing nature, but not urban, pictures significantly improved executive attention in both older and young adults as measured by the Attention Network Test, with similar effects seen in the two age groups. Alerting and orienting attention scores were not affected by picture viewing. This was the first study to show that viewing nature pictures improves attention in older adults, and to show that it is executive attention, specifically, that is improved. Among a growing number of interventions, nature exposure offers a quick, inexpensive, and enjoyable means to provide a temporary boost in executive attention.

    Environmental pests may serve as reservoirs and vectors of zoonotic pathogens to leafy greens; however, it is unknown whether insect pests feeding on plant tissues could redistribute these pathogens present on the surface of leaves to internal sites. This study sought to differentiate the degree of tissue internalization of Escherichia coli O157:H7 when applied at different populations on the surface of lettuce and spinach leaves, and to ascertain whether lettuce-infesting insects or physical injury could influence the fate of either surface or internalized populations of this enteric pathogen. No internalization of E. coli O157:H7 occurred when lettuce leaves were inoculated with 4.4 log CFU per leaf, but it did occur when inoculated with 6.4 log CFU per leaf. Internalization was statistically greater when spinach leaves were inoculated on the abaxial (underside) than when inoculated on the adaxial (topside) side, and when the enteric pathogen was spread after surface inoculation. Brief exposure (∼18 h) of lettuce leaves to insects (5 cabbage loopers, 10 thrips, or 10 aphids) prior to inoculation with E. coli O157:H7 resulted in significantly reduced internalized populations of the pathogen within these leaves after approximately 2 weeks, as compared with leaves not exposed to insects. Surface-contaminated leaves physically injured through file abrasions also had significantly reduced populations of both total and internalized E. coli O157:H7 as compared with nonabraded leaves 2 weeks after pathogen exposure.

    Reading Chinese, a kind of ideogram, relies more on visual cognition. The visuospatial cognitive deficit of Chinese dyslexia is an interesting topic that has received much attention. The purpose of current research was to explore the visuopatial cognitive characteristics of Chinese dyslexic children by studying their eye movements via a picture searching test. According to the diagnostic criteria defined by ICD-10, twenty-eight dyslexic children (mean age (10.12 +/- 1.42) years) were enrolled from the Clinic of Children Behavioral Disorder in the third affiliated hospital of Sun Yat-sen University. And 28 normally reading children (mean age (10.06 +/- 1.29) years), 1:1 matched by age, sex, grade and family condition were chosen from an elementary school in Guangzhou as a control group. Four groups of pictures (cock, accident, canyon, meditate) from Picture Vocabulary Test were chosen as eye movement experiment targets. All the subjects carried out the picture searching task and their eye movement data were recorded by an Eyelink II High-Speed Eye Tracker. The duration time, average fixation duration, average saccade amplitude, fixation counts and saccade counts were compared between the two groups of children. The dyslexic children had longer total fixation duration and average fixation duration (F = 7.711, P < 0.01; F = 4.520, P < 0.05), more fixation counts and saccade counts (F = 7.498, P < 0.01; F = 11.040, P < 0.01), and a smaller average saccade amplitude (F = 29.743, P < 0.01) compared with controls. But their performance in the picture vocabulary test was the same as those of the control group. The eye movement indexes were affected by the difficulty of the pictures and words, all eye movement indexes, except saccade amplitude, had a significant difference within groups (P < 0.05). Chinese dyslexic children have abnormal eye movements in picture searching, applying slow fixations, more fixations and small and frequent saccades. Their abnormal eye movement

    2005-01-01

    Full Text Available This article reviews recent research on perception of tangible pictures in sighted and blind people. Haptic picture naming accuracy is dependent upon familiarity and access to semantic memory, just as in visual recognition. Performance is high when haptic picture recognition tasks do not depend upon semantic memory. Viewpoint matters for the ease or difficulty of interpreting haptic pictures of solid objects. Top views were easiest for sighted and blind persons when geometrical solids had constant crosssections in the vertical axis. The presence or absence of viewpoint effects depends upon the nature of the solids that are represented. Congenitally blind people do not spontaneously produce perspective drawings, but recent data suggests that depictions including linear perspective can be understood after minimal experience. The results suggest that two-dimensional configurations are not necessarily problematic for touch.

    Full Text Available The Internet and Web-based technologies, as well as rapid globalization, are changing the way businesses communicate. Continuous progress in Information Technology (IT enables effective and efficient communication, particularly with the use of collaborative systems. Such systems have many different types of interfaces and attributes, and one such attribute is the use of visuals. This research assesses the usefulness of participant pictures in a collaborative exchange. To evaluate the usefulness of such pictures, participants were asked a series of questions regarding the use of pictures in CAMS, a collaborative environment. The results suggest that, in a collaborative setting, the use of pictures is valuable in enhancing a "sense of community," particularly in cases where participants have not met face-to-face.

    Pienaar, Jacques; Myers, Casey; Ralph, Timothy C.

    2011-01-01

    In the context of quantum field theory, the Heisenberg picture has a distinct advantage over the Schrodinger picture because the Schrodinger picture requires us to transform the vacuum state itself, which can be intractable in the case of non-inertial reference frames, whereas the Heisenberg picture allows us to keep the same vacuum state and only transform the operators. However, the Heisenberg calculation requires the operators to already be expressed as a function of creation and annihilation operators acting on the original vacuum, whereas calculations in quantum information and quantum computation use operators that act on qubit states, necessarily containing particles. The relationship between the operators acting on these states and the operators acting on the vacuum state has remained elusive. We derive such an expression using an explicit model for single-particle production from the vacuum.

    Full Text Available This article aims at identifying the individual and joint impact of two « country-level variables », namely national distance and country risk, on the survival of international joint ventures in emerging countries. Research hypotheses predicting the negative impact of national distance and country risk on survival are formulated in this article. These research hypotheses are tested in a sample of 165 international joint ventures that were formed in Brazil between 1974 and 2003. These joint ventures were subjected to an event history analysis over a period of time ranging from 1974 to 2005. The empirical results show that the intercultural dynamics increases the instability of international joint ventures whereas the survival of these alliances does not seem to be affected by the economic and political uncertainty of Brazil. Furthermore, the national distance between local and foreign partners has effects on survival that are variable according to the life cycle of international joint ventures.

    Full Text Available While many programs are available to edit phylogenetic trees, associating pictures with branch tips in an efficient and automatic way is not an available option. Here, we present TreePics, a standalone software that uses a web browser to visualize phylogenetic trees in Newick format and that associates pictures (typically, pictures of the voucher specimens to the tip of each branch. Pictures are visualized as thumbnails and can be enlarged by a mouse rollover. Further, several pictures can be selected and displayed in a separate window for visual comparison. TreePics works either online or in a full standalone version, where it can display trees with several thousands of pictures (depending on the memory available. We argue that TreePics can be particularly useful in a preliminary stage of research, such as to quickly detect conflicts between a DNA-based phylogenetic tree and morphological variation, that may be due to contamination that needs to be removed prior to final analyses, or the presence of species complexes.

    Glucocorticoids (GCs) are anti-inflammatory agents, but their use in cystic fibrosis (CF) is controversial. In CF, the early colonization with Pseudomonas aeruginosa is mainly due to nonmucoid strains that can internalize, and induce apoptosis in the epithelial cells. Uptake of P. aeruginosa by the epithelial cells and subsequent apoptosis may prevent colonization of P. aeruginosa in CF airways. In the airway epithelia, several other biological effects, including an anti-secretory role by decreasing intracellular Ca(2+) concentration have been described for this anti-inflammatory drug. However, the effects of GCs on the nonmucoid P. aeruginosa internalization and intracellular Ca(2+) in CF bronchial epithelial cells have not been evaluated. We used cultured human CF bronchial airway epithelial cell (CFBE) monolayers to determine P. aeruginosa internalization, apoptosis, and intracellular Ca(2+)concentration in CF bronchial epithelial cells. Cells were treated with IL-6, IL-8, dexamethasone, betamethasone, or budesonide. GCs in co-treatments with IL-6 reversed the effect of IL-6 by decreasing the internalization of P. aeruginosa in the CFBE cells. GCs decreased the extent of apoptosis in CFBE cells infected with internalized P. aeruginosa, and increased the intracellular Ca(2+) concentration. These findings suggest that if internalization of P. aeruginosa reduces infection, GC therapy would increase the risk of pulmonary infection by decreasing the internalization of P. aeruginosa in CF cells, but GCs may improve airway hydration by increasing the intracellular Ca(2+) concentration. Whether the benefits of GC treatment outweigh the negative effects is questionable, and further clinical studies need to be carried out.

    Full Text Available Several studies have investigated the neural responses triggered by emotional pictures, but the specificity of the involved structures such as the amygdala or the ventral striatum is still under debate. Furthermore, only few studies examined the association of stimuli’s valence and arousal and the underlying brain responses. Therefore, we investigated brain responses with functional magnetic resonance imaging of 17 healthy subjects to pleasant and unpleasant affective pictures with comparable arousal levels and afterwards assessed ratings of valence and arousal. As expected, unpleasant pictures strongly activated the right and left amygdala, the right hippocampus, and the medial occipital lobe, whereas pleasant pictures elicited significant activations in left occipital regions, and in parts of the medial temporal lobe. The direct comparison of unpleasant and pleasant pictures which were comparable in arousal clearly indicated stronger amygdala activation in response to the unpleasant pictures. Most important, correlational analyses revealed on the one hand that the arousal of unpleasant pictures was significantly associated with activations in the right amygdala and the left caudate body. On the other hand, valence of pleasant pictures was significantly correlated with activations in the right caudate head, extending to the nucleus accumbens (NAcc and the left dorso-lateral prefrontal cortex. These findings support the notion that the amygdala is primarily involved in processing of unpleasant stimuli, and the stronger the more arousing the stimuli are, whereas reward-related structures like the NAcc primarily responds to pleasant stimuli, the stronger the more positive the valence of these stimuli is.

    Since four-dimensional relativistic quantum field theories have all the desirable properties such as particle production, unitarity, and analyticity, they provide a useful way to gain theoretical knowledge not only for weak and electromagnetic processes but also for strong interactions. For the dynamics of strong interactions, because of the necessity of understanding all orders of perturbation theory, the simplest case is the high energy limit. After a brief review of the general features of elastic scattering in field theories, the need of developing a phenomenology in order to make contact with present and future experimental data is discussed. Such a phenomenology must satisfy the dual requirement of, on the one hand, giving an accurate description of hadronic experimental data at high energies and, on the other hand, having the s → infinity behavior obtained from field theories. Recent improvements on such a phenomenology are emphasized, and include better parametrization and proper Regge background and spin effects. In particular, the spin of the proton is taken into account by using the concept of hadronic matter current of Chou and Yang. In addition to the total and differential cross sections for ISABELLE energies, predictions are obtained for both polarization and R parameters for proton--proton elastic scattering. Sore theoretical problems for the future are outlined

    The literature examines the impact of firms' corporate social responsibility (CSR) activities on employees' organizational identification without considering that such activities tend to have different targets. This study explores how perceived external CSR (efforts directed toward external stakeholders) and perceived internal CSR (efforts directed toward employees) activities influence employees' organizational identification. In so doing, it examines the alternative underlying mechanisms through which perceived external and internal CSR activities build employees' identification. Applying the taxonomy prescribed by the group engagement model, the study argues that the effects of perceived external and internal CSR flow through two competing mechanisms: perceived external prestige and perceived internal respect, respectively. Further, it is suggested that calling orientation (how employees see their work contributions) moderates the effects induced by these alternative forms of CSR. The model draws on survey data collected from a sample of 414 employees across five large multinationals in Pakistan. The results obtained using structural equation modeling support these hypotheses, reinforcing the notion that internal and external CSR operate through different mediating mechanisms and more interestingly employees' calling orientation moderates these relationships to a significant degree. Theoretical contributions and practical implications of results are discussed in detail.

    The psychological impact of a cancer diagnosis can extend through treatment, well into cancer survivorship and can be influenced by a range of psychosocial resources. At different stages in this trajectory, optimism is known to affect well-being directly. This study focusing upon the potential to flourish after cancer, investigates the relationship between optimism and positive affect during cancer survivorship together with four possible mediators: social support, fighting spirit, internal health locus of control and cancer worry, all of which have been shown to be important predictors of well-being in cancer patients. Participants (n = 102) from online cancer forums completed standardized questionnaires, and path analysis confirmed that optimism had a direct effect on positive affect in cancer survivors. Social support and fighting spirit were also shown to be significant mediators of this relationship, accounting collectively for 50% of the variance in positive affect. Whilst cancer worry and internal health locus of control could be predicted from levels of optimism, they did not mediate the optimism-positive affect relationship. Efforts to promote optimism and thus encourage fighting spirit at diagnosis through treatment may be worthwhile interventions, as would ensuring appropriate social support through the trajectory.

Forty primary school children (boys and girls selected to participate in this study. Students splitted into two experimental groups with the technique of simple random sampling. The first group consisted of students who viewed and listened (pictures with narration group, while the second group consisted of students who viewed (pictures with on-screen text a presentation of triangles. A recall test was used to evaluate students’ comprehension. The results showed that students’ comprehension was better when triangles' presentation (pictures was accompanied with spoken words, than with printed words. The pictures with narration group performed better than the pictures with on-screen text group, in recall test (M = 4.97, SD = 1.32 p<0.01. Results are consistent with the modality principle in which learners are more likely to build connections between corresponding words and pictures when words are presented in a spoken form (narration simultaneously with pictures.

  11. Additive effects of threat-of-shock and picture valence on startle reflex modulation.

    Directory of Open Access Journals (Sweden)

    Florian Bublatzky

    Full Text Available The present study examined the effects of sustained anticipatory anxiety on the affective modulation of the eyeblink startle reflex. Towards this end, pleasant, neutral and unpleasant pictures were presented as a continuous stream during alternating threat-of-shock and safety periods, which were cued by colored picture frames. Orbicularis-EMG to auditory startle probes and electrodermal activity were recorded. Previous findings regarding affective picture valence and threat-of-shock modulation were replicated. Of main interest, anticipating aversive events and viewing affective pictures additively modulated defensive activation. Specifically, despite overall potentiated startle blink magnitude in threat-of-shock conditions, the startle reflex remained sensitive to hedonic picture valence. Finally, skin conductance level revealed sustained sympathetic activation throughout the entire experiment during threat- compared to safety-periods. Overall, defensive activation by physical threat appears to operate independently from reflex modulation by picture media. The present data confirms the importance of simultaneously manipulating phasic-fear and sustained-anxiety in studying both normal and abnormal anxiety.

    Affective computing aims at the detection of users' mental states, in particular, emotions and dispositions during human-computer interactions. Detection can be achieved by measuring multimodal signals, namely, speech, facial expressions and/or psychobiology. Over the past years, one major approach was to identify the best features for each signal using different classification methods. Although this is of high priority, other subject-specific variables should not be neglected. In our study, we analyzed the effect of gender, age, personality and gender roles on the extracted psychobiological features (derived from skin conductance level, facial electromyography and heart rate variability) as well as the influence on the classification results. In an experimental human-computer interaction, five different affective states with picture material from the International Affective Picture System and ULM pictures were induced. A total of 127 subjects participated in the study. Among all potentially influencing variables (gender has been reported to be influential), age was the only variable that correlated significantly with psychobiological responses. In summary, the conducted classification processes resulted in 20% classification accuracy differences according to age and gender, especially when comparing the neutral condition with four other affective states. We suggest taking age and gender specifically into account for future studies in affective computing, as these may lead to an improvement of emotion recognition accuracy.

  14. Emotionally negative pictures enhance gist memory.

    Bookbinder, S H; Brainerd, C J

    2017-02-01

    In prior work on how true and false memory are influenced by emotion, valence and arousal have often been conflated. Thus, it is difficult to say which specific effects are caused by valence and which are caused by arousal. In the present research, we used a picture-memory paradigm that allowed emotional valence to be manipulated with arousal held constant. Negatively valenced pictures elevated both true and false memory, relative to positive and neutral pictures. Conjoint recognition modeling revealed that negative valence (a) reduced erroneous suppression of true memories and (b) increased the familiarity of the semantic content of both true and false memories. Overall, negative valence impaired the verbatim side of episodic memory but enhanced the gist side, and these effects persisted even after a week-long delay.

    The amount of digital images taken by the average consumer is consistently increasing. People enjoy the convenience of storing and sharing their pictures through online (digital) and offline (traditional) media. A set of pictures can be uploaded to: online photo services, web blogs and social network websites. Alternatively, these images can be used to generate: prints, cards, photo books or other photo products. Through uploading and sharing, images are easily transferred from one format to another. And often, a different set of associated content (text, tags) is created across formats. For example, on his web blog, a user may journal his experiences of his recent travel; on his social network website, his friends tag and comment on the pictures; in his online photo album, some pictures are titled and keyword-tagged. When the user wants to tell a complete story, perhaps in a photo book, he must collect, across all formats: the pictures, writings and comments, etc. and organize them in a book format. The user has to arrange the content of his trip in each format. The arrangement, the associations between the images, tags, keywords and text, cannot be shared with other formats. In this paper, we propose a system that allows the content to be easily created and shared across various digital media formats. We define a uniformed data association structure to connect: images, documents, comments, tags, keywords and other data. This content structure allows the user to switch representation formats without reediting. The framework under each format can emphasize (display or hide) content elements based on preference. For example, a slide show view will emphasize the display of pictures with limited text; a blog view will display highlighted images and journal text; and the photo book will try to fit in all images and text content. In this paper, we will discuss the strategy to associate pictures with text content, so that it can naturally tell a story. We will also list

    Full Text Available The world of children is a world of play, and learning is done with or while playing that involves all the senses of the child. Paud teachers and parents need to look at the aspects of personality that exist in the development of children, including aspects of cognitive aspects, aspects of moral values, aspects of intelligence, motor aspects, social aspects of emotional. These five aspects may affect the thinking aspect of the child, and this is highly dependent on the ability of each individual. Therefore, children need to get good and proper stimulation to optimize aspects of its development. This study aims to determine the application of cooperative learning picture and picture type in improving early childhood cognitive development in KB Mawar FKIP Unpatti Ambon. This research is a Classroom Action Research. The subjects of this study were students aged 4-5 years KB Roses FKIP Unpatti Ambon which amounted to 10 people. Data collection techniques are observation and interview. This classroom action research procedure is carried out in two cycles, namely cycle I and cycle II. To know the result of student learning by using learning strategy with song on cognitive aspect conducted evaluation in the form of observation to cognitive aspect. Where indicators are performed by holding observations after completion of learning in each cycle at the end of the second meeting. The results showed that in the first cycle, there are still students who do not meet the criteria of the indicators conducted by the tutor, so it can be said as a weakness encountered in the implementation of the first cycle action, while in cycle II students are very active hear the teacher explanation. Very active in question is that students can follow the teacher's explanation well so that what is assigned can be done well. Thus it can be concluded that by using cooperative learning picture and picture type can develop early childhood cognitive in KB Mawar FKIP Unpatti Ambon

    This study evaluated differences in the amplitude of startle reflex and Sensitivity to Reward (SR) and Sensitivity to Punishment (SP) personality variables of the Reinforcement Sensitivity Theory (RST). We hypothesized that subjects with higher scores in SR would obtain a higher startle reflex when exposed to pleasant pictures than lower scores, while higher scores in SP would obtain a higher startle reflex when exposed to unpleasant pictures than subjects with lower scores in this dimension. The sample consisted of 112 healthy female undergraduate psychology students. Personality was assessed using the short version of the Sensitivity to Punishment and Sensitivity Reward Questionnaire (SPSRQ). Laboratory anxiety was controlled by the State Anxiety Inventory. The startle blink reflex was recorded electromyographically (EMG) from the right orbicularis oculi muscle as a response to the International Affective Picture System (IAPS) pleasant, neutral and unpleasant pictures. Subjects higher in SR obtained a significant higher startle reflex response in pleasant pictures than lower scorers (48.48 vs 46.28, p<0.012). Subjects with higher scores in SP showed a light tendency of higher startle responses in unpleasant pictures in a non-parametric local regression graphical analysis (LOESS). The findings shed light on the relationships among the impulsive-disinhibited personality, including sensitivity to reward and emotions evoked through pictures of emotional content.

    Immigrants to Westernized countries adopt the prevalence of allergic diseases of native populations, yet no data are available on immigrants to low-income or low-disease prevalence countries. We investigated these questions using data from the International Study of Asthma and Allergies in Childhood. Standardized questionnaires were completed by 13-14-year-old adolescents and by the parent/guardians of 6-7-year-old children. Questions on the symptom prevalence of asthma, rhinoconjunctivitis and eczema, and a wide range of factors postulated to be associated with these conditions, including birth in or not in the country and age at immigration, were asked. Odds ratios for risk of the three diseases according to immigration status were calculated using generalized linear mixed models. These were adjusted for: world region; language and gross national income; and individual risk factors including gender, maternal education, antibiotic and paracetamol use, maternal smoking, and diet. Effect modification by gross national income and by prevalence was examined. There were 326 691 adolescents from 48 countries and 208 523 children from 31 countries. Immigration was associated with a lower prevalence of asthma, rhinoconjunctivitis and eczema in both age groups than among those born in the country studied, and this association was mainly confined to high-prevalence/affluent countries. This reduced risk was greater in those who had lived fewer years in the host country. Recent migration to high prevalence/affluent countries is associated with a lower prevalence of allergic diseases. The protective pre-migration environment quickly decreases with increasing time in the host country. © The Author 2014; all rights reserved.

  19. Implicit and explicit attention to pictures and words: An fMRI-study of concurrent emotional stimulus processing

    Full Text Available The present study utilized functional magnetic resonance imaging (fMRI to examine the neural processing of concurrently presented emotional stimuli under varying explicit and implicit attention demands. Specifically, in separate trials, participants indicated the category of either pictures or words. The words were placed over the center of the pictures and the picture-word compound-stimuli were presented for 1500 ms in a rapid event-related design. The results reveal pronounced main effects of task and emotion: the picture categorization task prompted strong activations in visual, parietal, temporal, frontal, and subcortical regions; the word categorization task evoked increased activation only in left extrastriate cortex. Furthermore, beyond replicating key findings regarding emotional picture and word processing, the results point to a dissociation of semantic-affective and sensory-perceptual processes for words: while emotional words engaged semantic-affective networks of the left hemisphere regardless of task, the increased activity in left extrastriate cortex associated with explicitly attending to words was diminished when the word was overlaid over an erotic image. Finally, we observed a significant interaction between Picture Category and Task within dorsal visual-associative regions, inferior parietal, and dorsolateral and medial prefrontal cortices: during the word categorization task, activation was increased in these regions when the words were overlaid over erotic as compared to romantic pictures. During the picture categorization task, activity in these areas was relatively decreased when categorizing erotic as compared to romantic pictures. Thus, the emotional intensity of the pictures strongly affected brain regions devoted to the control of task-related word or picture processing. These findings are discussed with respect to the interplay of obligatory stimulus processing with task-related attentional control mechanisms.

    Picture naming has been used by vision researchers to study object identification, by language researchers to study word production, and by memory researchers to study implicit memory. Response times for naming repeated pictures decrease with successive repetitions. Repetition priming in picture naming involves an implicit, nonhippocampal form of memory. In this review, the processes speeded with repetition are decomposed, the time course of the effect is characterized, the factors affecting the magnitude of priming are enumerated, and possible mechanisms of priming are evaluated. Both behavioral response time and neuroimaging studies are considered. The processes that are speeded with repetition include high-level object identification and word production processes, but not low-level visual processes or articulation. Repetition priming lasts for at least several weeks and follows a typical forgetting function. The mechanism of priming is concluded to be speeded completion of the component processes of picture naming.

    In this paper, the natural and induced space environment factors affecting materials performance on ISS are described in some detail. The emphasis will be on ISS flight experience and the more significant design and development issues of the last two years. The intent is to identify and document the set of space environment factors, affecting materials, that are producing the largest impacts on the ISS flight hardware verification and acceptance process and on ISS flight operations. Orbital inclination (S1.6 ) and altitude (nominal3S0 km to 400 km altitude) determine the set of natural environment factors affecting the functional life of materials and subsystems on ISS. ISS operates in the F2 region of Earth's ionosphere in well-defined fluxes of atomic oxygen, other ionospheric plasma species, and solar UV, VUV, and x-ray radiation, as well as galactic cosmic rays, trapped radiation, and solar cosmic rays (1,2). The high latitude orbital environment also exposes external surfaces to significantly less well-defined or predictable fluxes of higher energy trapped electrons and auroral electrons (3 ,4). The micrometeoroid and orbital debris environment is an important determinant of spacecraft design and operations in any orbital inclination. Environment factors induced by ISS flight operations include ram-wake effects, magnetic induction voltages arising from flight through Earth's magnetic field, hypergolic thruster plume impingement from proximity operations of visiting vehicles, materials outgassing, venting and dumping of fluids, ISS thruster operations, as well as specific electrical power system interactions with the ionospheric plasma (S-7). ISS must fly in a very limited number of approved flight attitudes leading to location specific environmental exposures and extreme local thermal environments (8). ISS is a large vehicle and produces a deep wake structure from which both ionospheric plasma and neutrals (atomic oxygen) are largely excluded (9-11). At high

    What do toddlers learn from everyday picture-book reading interactions? To date, there has been scant research exploring this question. In this study, the authors adapted a standard imitation procedure to examine 18- to 30-month-olds' ability to learn how to reenact a novel action sequence from a picture book. The results provide evidence that toddlers can imitate specific target actions on novel real-world objects on the basis of a picture-book interaction. Children's imitative performance after the reading interaction varied both as a function of age and the level of iconicity of the pictures in the book. These findings are discussed in terms of children's emerging symbolic capacity and the flexibility of the cognitive representation.

    To explore the psychological impact of weight labels. A double-blind experiment that randomly informed participants that they were "normal weight" or "overweight." Public university in Honolulu, Hawai'i. Normal-weight and overweight female undergraduates (N = 113). The Body Image States Scale, Stunkard Rating Scale, Weight Bias Internalization Scale, Positive and Negative Affect Schedule, General Health question from the 12-item Short Form Health Survey, modified version of the Weight Loss Methods Scale, and a manipulation check. A 2 × 2 between-subjects analysis of variance explored the main effects of the assigned weight label and actual weight and interactions between assigned weight label and actual weight. Significant main effects of the assigned weight label emerged on measures of body dissatisfaction, F(1, 109) = 12.40, p = .001, [Formula: see text] = 0.10, internalized weight stigma, F(1, 108) = 4.35, p = .039, [Formula: see text] = .04, and negative affect, F(1, 108) = 9.22, p = .003, [Formula: see text] = .08. Significant assigned weight label × actual weight interactions were found on measures of perceived body image, F(1, 109) = 6.29, p = .014, [Formula: see text] = .06, and perceived health, F(1, 109) = 4.18, p = .043, [Formula: see text] = .04. A weight label of "overweight" may have negative psychological consequences, particularly for overweight women.

    An ideal antibiofilm strategy is to control both in the quality and quantity of biofilm while maintaining the benefits derived from resident microflora. Vizantin, a recently developed immunostimulating compound, has also been found to have antibiofilm property. This study evaluated the influence on biofilm formation of Streptococcus mutans in the presence of sulfated vizantin and biofilm development following bacterial adhesion on a hydroxyapatite disc coated with sulfated vizantin. Supplementation with sulfated vizantin up to 50 μM did not affect either bacterial growth or biofilm formation, whereas 50 μM sulfated vizantin caused the biofilm to readily detach from the surface. Sulfated vizantin at the concentration of 50 μM upregulated the expression of the gtfB and gtfC genes, but downregulated the expression of the gtfD gene, suggesting altered architecture in the biofilm. Biofilm development on the surface coated with sulfated vizantin was inhibited depending on the concentration, suggesting prevention from bacterial adhesion. Among eight genes related to bacterial adherence in S. mutans, expression of gtfB and gtfC was significantly upregulated, whereas the expression of gtfD, GbpA and GbpC was downregulated according to the concentration of vizantin, especially with 50 μM vizantin by 0.8-, 0.4-, and 0.4-fold, respectively. These findings suggest that sulfated vizantin may cause structural degradation as a result of changing gene regulation related to bacterial adhesion and glucan production of S. mutans.

    Destruction of health systems in fragile and conflict-affected states increases civilian mortality. Despite the size, scope, scale and political influence of international security forces intervening in fragile states, little attention has been paid to array of ways they may impact health systems beyond their effects on short-term humanitarian health aid delivery. Using case studies we published on international security forces' impacts on health systems in Haiti, Kosovo, Afghanistan and Libya, we conducted a comparative analysis that examined three questions: What aspects, or building blocks, of health systems did security forces impact across the cases and what was the nature of these impacts? What forums or mechanisms did international security forces use to interact with health system actors? What policies facilitated or hindered security forces from supporting health systems? We found international security forces impacted health system governance, information systems and indigenous health delivery organizations. Positive impacts included bolstering the authority, transparency and capability of health system leadership. Negative impacts included undermining the impartial nature of indigenous health institutions by using health projects to achieve security objectives. Interactions between security and health actors were primarily ad hoc, often to the detriment of health system support efforts. When international security forces were engaged in health system support activities, the most helpful communication and consultative mechanisms to manage their involvement were ones that could address a wide array of problems, were nimble enough to accommodate rapidly changing circumstances, leveraged the power of personal relationships, and were able to address the tensions that arose between security and health system supporting strategies. Policy barriers to international security organizations participating in health system support included lack of mandate, conflicts

    Substantial improvement in the intelligibility of defocussed pictures has been demonstrated using coherent optical processing. Correction for penumbra effects, such as arise in radiography, has been demonstrated at optical wavelengths. Compensation for a Gaussian spread function, such as might occur in radiography via a salt screen, has also been demonstrated. A simulation has shown that much greater enhancement could be expected if improved phase filters could be made

    Full Text Available The newly developed Complex Picture Test (CPT examines main cognitive domains, especially perceptual and visual-spatial abilities. The potential usefulness of the CPT in the assessment of dementia was evaluated. Patients with different forms of dementia [14 vascular dementia (VaD, 30 Alzheimer’s disease (AD, 6 Parkinson’s disease dementia (PDD], 12 subjects with mild cognitive impairment (MCI, and 30 matched controls were examined by the CPT, Mini-Mental State Examination (MMSE, the WAIS-R Digit Span subtest, and the Clock Drawing Test (CDT. The CPT consists of 10 complex pictures, each presenting characteristics paradoxically in opposition to each other. The subjects scored points for naming the object and noticing the paradox. One point was added for commenting on the paradox without prompting (3 points each picture/maximum of 30. CPT scores were significantly higher in the control group (mean ± SD, 29.46 ± 1.43 than in the AD, VaD, MCI, and PDD groups (13.1 ± 2.3, 16.9 ± 3.5, 23.2 ± 1.4, and 23.6 ± 3.4, respectively; p < 0.05. Significant positive correlations between MMSE, Digit Span, CDT, and CPT scores were observed (rho 0.76, 0.35, and 0.56, respectively. These data show perception of complex pictures being compromised in dementia. The correlation between CPT scores and MMSE scores suggests that tests may be used as a brief screening tool for dementia.

    The analysis of speech error corpora in various gender-marked languages has shown that noun substitutions tend to preserve grammatical gender. This result has been taken as an indication that grammatical gender could play a constraining role during the process of lexical selection. To gain insights on the status of grammatical gender in the speech production system, we discuss this hypothesis and we report three picture naming experiments. We attempted to observe gender-marked context effects in the course of error-free speech production. Participants named pictures shortly after processing a prime that was or was not gender marked and that was or was not congruent with the name of the picture. A clear congruency effect was observed, involving both facilitation in the gender congruent conditions and inhibition in gender incongruent conditions. Different interpretations of this effect and of previously reported gender context effects are discussed in the context of current models of speech production. Copyright 2004 Elsevier B.V.

    Full Text Available Proceeding from the idea of the readymade, Marko Ristić’s, Vane Bor’s and Dušan Matić’s collages regroup readymade pictorial and textual matrices according to the rules of free associative syntax. Everything that they collected cut out and pasted bears the hallmark of personal choice, i.e. objective chance, as the Surrealists would say. In the new structure of the collage, picture and text were of equal importance. However, we should not forget that both picture and text were only fragments, of different origin so that they could not function as autonomous elements in their own right nor could they establish logical interlinks. Cut and paste picture in Surrealism are primarily registered as visual wholes, in which the former principle of harmony has been substituted by the principle of discontinuity. In fact, they do not aspire to establish closed and unambiguous semantic structures either on a single paper or within a cycle, disregarding as they do conventional narrative and illustrative order in representing reality.

  11. A Spectrum is Worth a Thousand Pictures

    Gelderman, Richard F.

    2006-12-01

    A wise astronomer once pointed out that if a picture is worth a thousand words, then a spectrum is worth a thousand pictures. Unfortunately, spectra are rarely emphasized in the introductory astronomy courses and few students exit such a course with any meaningful understanding or appreciation of spectroscopy. Part of the problem is lack of background knowledge; the typical introductory astronomy student has little experience with spectroscopy or atomic physics. Another issue is that spectra are not pretty pictures and are not intuitively understandable. We present and discuss a series of “minds-on” exercises and activities built into a college-level “stars, galaxies, and cosmology” intro astronomy course. The lessons are structured to help students improve their ability to recognize patterns and improve their ability to really see the details in front of them. Another goal is for students to realize there is “more than meets the eye” to learn how to discover “hidden” diagnostics, such as different sources of light their eyes see as white light. A curriculum that emphasizes spectroscopy also provides the opportunity to stress the story of the “Harvard Women,” a tale that bridges gender gaps and often humanizes scientists in the eyes of non-science majors. Finally, with a solid foundation in spectroscopy, students are better prepared to understand exciting topics such as Hubble’s Law and the importance of primordial nucleosynthesis.

    Sleep deprivation (SD) negatively affects various cognitive performances, but surprisingly evidence about a specific impact of sleep loss on subjective evaluation of emotional stimuli remains sparse. In the present study, we assessed the effect of SD on the emotional rating of standardized visual stimuli selected from the International Affective Picture System. Forty university students were assigned to the sleep group (n=20), tested before and after one night of undisturbed sleep at home, or to the deprivation group, tested before and after one night of total SD. One-hundred and eighty pictures (90 test, 90 retest) were selected and categorized as pleasant, neutral and unpleasant. Participants were asked to judge their emotional reactions while viewing pictures by means of the Self-Assessment Manikin. Subjective mood ratings were also obtained by means of Visual Analog Scales. No significant effect of SD was observed on the evaluation of pleasant and unpleasant stimuli. On the contrary, SD subjects perceived the neutral pictures more negatively and showed an increase of negative mood and a decrease of subjective alertness compared to non-deprived subjects. Finally, an analysis of covariance on mean valence ratings of neutral pictures using negative mood as covariate confirmed the effect of SD. Our results indicate that sleep is involved in regulating emotional evaluation. The emotional labeling of neutral stimuli biased toward negative responses was not mediated by the increase of negative mood. This effect can be interpreted as an adaptive reaction supporting the "better safe than sorry" principle. It may also have applied implications for healthcare workers, military and law-enforcement personnel. Copyright 2010 Elsevier Inc. All rights reserved.

  14. A mental picture of the greenhouse effect. A pedagogic explanation

    Science.gov (United States)

    Benestad, Rasmus E.

    2017-05-01

    The popular picture of the greenhouse effect emphasises the radiation transfer but fails to explain the observed climate change. An old conceptual model for the greenhouse effect is revisited and presented as a useful resource in climate change communication. It is validated against state-of-the-art data, and nontraditional diagnostics show a physically consistent picture. The earth's climate is constrained by well-known and elementary physical principles, such as energy balance, flow, and conservation. Greenhouse gases affect the atmospheric optical depth for infrared radiation, and increased opacity implies higher altitude from which earth's equivalent bulk heat loss takes place. Such an increase is seen in the reanalyses, and the outgoing long-wave radiation has become more diffuse over time, consistent with an increased influence of greenhouse gases on the vertical energy flow from the surface to the top of the atmosphere. The reanalyses further imply increases in the overturning in the troposphere, consistent with a constant and continuous vertical energy flow. The increased overturning can explain a slowdown in the global warming, and the association between these aspects can be interpreted as an entanglement between the greenhouse effect and the hydrological cycle, where reduced energy transfer associated with increased opacity is compensated by tropospheric overturning activity.

    2017-10-01

    This study examined how exposure to pictures of women with different body sizes (thin, obese), physical attractiveness levels (attractive, unattractive), along with exposure to weight-related messages (pro-anorexia, anti-anorexia) embedded in a fashion website affected female participants' planned behavior toward weight loss. Participants exposed to attractive model pictures showed higher intentions, attitudes, and subjective norms to lose weight compared with unattractive models. Additionally, participants exposed to thin and attractive model pictures indicated the highest attitudes and self-efficacy to lose weight, whereas those exposed to thin and unattractive model pictures indicated the lowest. Furthermore, weight-related messages moderated the effect of model appearance (body size and attractiveness) on controllability of weight-loss activities. However, website pictures' body size differences had no main effects on planned behavior toward weight loss. These effects are discussed in the light of social comparison mechanisms.

    Full Text Available Twenty three years ago, numb was identified as a critical regulator in Drosophila sensory organ precursor cell asymmetric divisions. Beyond the recently recognized role in carcinogenesis, Numb seems to be important in Alzheimer’s disease. This assertion comes from the involvement in various processes such as synapse morphogenesis, APP trafficking, notch signaling and neurogenesis. The purpose of the present mini-review is to provide the current picture of Numb’s participation in mechanisms underlying Alzheimer’s disease pathogenesis and emphasize potential aspects for future research.

    Full Text Available Abstract Background The genome-wide association study (GWAS is a useful approach to identify genes affecting economically important traits in dairy cattle. Here, we report the results from a GWAS based on high-density SNP genotype data and estimated breeding values for nine production, fertility, body conformation, udder health and workability traits in the Brown Swiss cattle population that is part of the international genomic evaluation program. Result GWASs were performed using 50 k SNP chip data and deregressed estimated breeding values (DEBVs for nine traits from between 2061 and 5043 bulls that were part of the international genomic evaluation program coordinated by Interbull Center. The nine traits were milk yield (MY, fat yield (FY, protein yield (PY, lactating cow’s ability to recycle after calving (CRC, angularity (ANG, body depth (BDE, stature (STA, milk somatic cell score (SCS and milk speed (MSP. Analyses were performed using a linear mixed model correcting for population confounding. A total of 74 SNPs were detected to be genome-wide significantly associated with one or several of the nine analyzed traits. The strongest signal was identified on chromosome 25 for milk production traits, stature and body depth. Other signals were on chromosome 11 for angularity, chromosome 24 for somatic cell score, and chromosome 6 for milking speed. Some signals overlapped with earlier reported QTL for similar traits in other cattle populations and were located close to interesting candidate genes worthy of further investigations. Conclusions Our study shows that international genetic evaluation data is a useful resource for identifying genetic factors influencing complex traits in livestock. Several genome wide significant association signals could be identified in the Brown Swiss population, including a major signal on BTA25. Our findings report several associations and plausible candidate genes that deserve further exploration in other

    Denitrification is an important pathway for nitrate transformation in marine sediments, and this process has been observed to be negatively affected by engineered nanomaterials. However, previous studies only focused on the potential effect of a certain type of nanomaterial on microbial denitrification. Here we show that the toxicity of CuO nanoparticles (NPs) to denitrification in marine sediments is highly affected by the presence of carbon nanotubes (CNTs). It was found that the removal efficiency of total NOX−-N (NO3−-N and NO2−-N) in the presence of CuO NPs was only 62.3%, but it increased to 81.1% when CNTs appeared in this circumstance. Our data revealed that CuO NPs were more easily attached to CNTs rather than cell surface because of the lower energy barrier (3.5 versus 36.2 kT). Further studies confirmed that the presence of CNTs caused the formation of large, incompact, non-uniform dispersed, and more negatively charged CuO-CNTs heteroaggregates, and thus reduced the nanoparticle internalization by cells, leading to less toxicity to metabolism of carbon source, generation of reduction equivalent, and activities of nitrate reductase and nitrite reductase. These results indicate that assessing nanomaterial-induced risks in real circumstances needs to consider the “mixed” effects of nanomaterials. PMID:27279546

  15. Decreased pain perception by unconscious emotional pictures

    2016-10-01

    Full Text Available Pain perception arises from a complex interaction between a nociceptive stimulus and different emotional and cognitive factors, which appear to be mediated by both automatic and controlled systems. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, emotional influences on pain under unaware conditions are much less known. The aim of the present study was to investigate the modulation of pain perception by unconscious emotional pictures through an emotional masking paradigm. Two kinds of both somatosensory (painful and non-painful and emotional stimulation (negative and neutral pictures were employed. Fifty pain-free participants were asked to rate the perception of pain they were feeling in response to laser-induced somatosensory stimuli as faster as they can. Data from pain intensity and reaction times were measured. Statistical analyses revealed a significant effect for the interaction between pain and emotional stimulation, but surprisingly this relationship was opposite to expected. In particular, lower pain intensity scores and longer reaction times were found in response to negative images being strengthened this effect for painful stimulation. Present findings suggest a clear pain perception modulation by unconscious emotional contexts. Attentional capture mechanisms triggered by unaware negative stimulation could explain this phenomenon leading to a withdrawal of processing resources from pain.

  16. TIFF, GIF, and PNG: get the picture?

    2007-01-01

    GIF, JPEG, and PNG are most likely the best formats to use for three reasons. First, they're standardized and open formats for anyone to use. In addition, JPEG is an ISO standard and PNG is an IETF RFC (Internet Engineering Task Force Request for Comments-www.ietf.org) and W3C recommendation (World Wide Web Consortium-www.w3.org). Second, they're compressible. GIF files are generally compressed at 5:1, JPEG at 10:1 or 20:1 and PNG at about 7:1. Finally, they're all supported by web browsers. Well, pretty much. Microsoft's Internet Explorer doesn't support the alpha channel transparency for PNG-but, on the other hand, GIF and JPEG don't have the alpha channel at all. Use TIFF to archive your original pictures as it is a lossless format. Check out the summary table and sidebar for more information regarding these picture file formats.

    2018-01-01

    The present study used the presentation of food pictures and judgements about their duration to assess the emotions elicited by food in women suffering from an eating disorder (ED). Twenty-three women diagnosed with an ED, namely anorexia (AN) or bulimia nervosa (BN), and 23 healthy controls (HC) completed a temporal bisection task and a duration discrimination task. Intervals were marked with emotionally pre-rated pictures of joyful and disgusting food, and pictures of neutral objects. The results showed that, in the bisection task, AN women overestimated the duration of food pictures in comparison to neutral ones. Also, compared to participants with BN, they perceived the duration of joyful food pictures as longer, and tended to overestimate the duration of the disgusting ones. These effects on perceived duration suggest that AN women experienced an intense reaction of fear when they were confronted to food pictures. More precisely, by having elevated the arousal level and activated the defensive system, food pictures seemed to have speeded up the rhythm of the AN participants' internal clock, which led to an overestimation of images' duration. In addition, the results revealed that, in both tasks, ED women presented a lower temporal sensitivity than HC, which was related to their ED symptomatology (i.e., BMI, restraint and concern) and, particularly, to their weaker cognitive abilities in terms of attention, processing speed and working memory. Considered all together, the findings of the present experiment highlight the role of fear and anxiety in the manifestations of AN and point out the importance of considering non-temporal factors in the interpretation of time perception performance.

    The well-documented increases in obesity and unhealthy dietary practices substantiate the need for evidence-based tools that can help people improve their dietary habits. The current spread of mobile phone-embedded cameras offers new opportunities for recording food intake. Moreover, the act of taking pictures of food consumed may enhance visual consciousness of food choice and quantity. The present study aimed to assess the effect of using cell phone pictures to record food intake on energy intake and food choice in college students. The effectiveness and acceptability of cell phone picture-based diet recording also was assessed. A repeated measures crossover design was used. One group of participants entered their food intake online during 3 days based on their memory, although a second group recorded their food intake using cell phone pictures as their reference. Participants then crossed over to complete 3 more days of diet recording using the alternate method. Focus groups were conducted to obtain feedback on the effectiveness and acceptability of cell phone picture-based diet recording. Intake of meat and vegetable servings were significantly higher in the memory period compared with the cell phone period, regardless of the order. Results from the focus group indicated a positive attitude toward the use of cell phone pictures in recording food intake and an increased awareness of food choice and portion size. Cell phone pictures may be an easy, relevant, and accessible method of diet self-monitoring when aiming at dietary changes. Future trials should combine this technique with healthy eating education. © 2015 Sigma Theta Tau International.

    Below are all of the pictures for the CNEC and CVT measurements performed at the DAF in July 2016. In total there are 165 pictures. The photos on pages 2-105 were taken during the first week of measurements and the photos on pages 106-165 were taken during the second week of measurements. Many photos are applicable to both sets, which is why it is best to keep the entire set together. For most configurations, a description of the configuration was written on a white board; photos of the measurement setup were taken, then a photo of the white board was taken. For example, the pictures on pages 6-19 (which precede a white board picture on page 20) are of the configuration with Rocky Flats Shells 1-2 surrounded by 4 AmLi sources, which is listed on the white board picture on page 20. In some cases, the white board picture precedes the configuration pictures.

  4. A cinema for the unborn: moving pictures, mental pictures and Electra Sparks's New Thought film theory.

    Science.gov (United States)

    Ellis, Patrick

    2017-09-01

    In the 1910s, New York suffragette Electra Sparks wrote a series of essays in the Moving Picture News that advocated for cine-therapy treatments for pregnant women. Film was, in her view, the great democratizer of beautiful images, providing high-cultural access to the city's poor. These positive 'mental pictures' were important for her because, she claimed, in order to produce an attractive, healthy child, the mother must be exposed to quality cultural material. Sparks's championing of cinema during its 'second birth' was founded upon the premise of New Thought. This metaphysical Christian doctrine existed alongside the self-help and esoteric publishing domains and testified, above all, to the possibility of the 'mind-cure' of the body through the positive application of 'mental pictures'. Physiologically, their method began best in the womb, where the thoughts of the mother were of utmost importance: the eventual difference between birthing an Elephant Man or an Adonis. This positive maternal impression was commonplace in New Thought literature; it was Sparks's innovation to apply it to cinema. Investigating Sparks's film theory, practice and programming reveals her to be a harbinger of the abiding analogy between mind and motion picture that occupies film theorists to this day.

    In the last decades, food pictures have been repeatedly employed to investigate the emotional impact of food on healthy participants as well as individuals who suffer from eating disorders and obesity. However, despite their widespread use, food pictures are typically selected according to each researcher's personal criteria, which make it difficult to reliably select food images and to compare results across different studies and laboratories. Therefore, to study affective reactions to food, it becomes pivotal to identify the emotional impact of specific food images based on wider samples of individuals. In the present paper we introduce the Open Library of Affective Foods (OLAF), which is a set of original food pictures created to reliably select food pictures based on the emotions they prompt, as indicated by affective ratings of valence, arousal, and dominance and by an additional food craving scale. OLAF images were designed to allow simultaneous use with affective images from the International Affective Picture System (IAPS), which is a well-known instrument to investigate emotional reactions in the laboratory. The ultimate goal of the OLAF is to contribute to understanding how food is emotionally processed in healthy individuals and in patients who suffer from eating and weight-related disorders. The present normative data, which was based on a large sample of an adolescent population, indicate that when viewing affective non-food IAPS images, valence, arousal, and dominance ratings were in line with expected patterns based on previous emotion research. Moreover, when viewing food pictures, affective and food craving ratings were consistent with research on food cue processing. As a whole, the data supported the methodological and theoretical reliability of the OLAF ratings, therefore providing researchers with a standardized tool to reliably investigate the emotional and motivational significance of food. The OLAF database is publicly available at zenodo.org.

Computer-generated illustrations in color are used extensively throughout the text, helping to establish the relation between quantum mechanics—wave functions, interference, atomic structure, and so forth—and classical physics—point mechanics, statistical mechanics, and wave optics. Even more important, by studying the pictures in parallel with the text, readers develop an intuition for such notoriously abstract phenomena as • the tunnel effect • excitation and decay of metastable states • wave-packet motion within a well • systems of distinguishable and indistinguishable particles • free wave packets and scattering in 3 dimensions • angular-momentum decomposition • stationary bound states in various 3-dimensional potentials • hybrid states • Kepler motion of wave packets in the Coulomb field • spin and magnetic resonance Illustrations from experiments in a variety of f...

    2011-02-01

    The semantic abilities of children with pragmatic language impairment (PLI) are subject to debate. The authors investigated picture naming and definition skills in 5-year-olds with PLI in comparison to typically developing children. 84 children with PLI and 80 age-matched typically developing children completed receptive vocabulary, picture naming, and definition tasks. The PLI group scored lower on the receptive vocabulary and picture naming tasks. Word length and frequency affected naming accuracy in both groups. Children with PLI showed higher numbers of semantic errors, nonrelated errors, and omissions and circumlocutions. The error-type distribution differed between groups: PLI children showed disproportionate levels of nonrelated errors. In the definition task, PLI children showed lower information accuracy for accurately named pictures and comparable accuracy for incorrectly named pictures. Qualitative analysis suggested a high incidence of pragmatically inappropriate definitions for the PLI group. Naming accuracy for both groups improved equally after giving semantic cues. These findings suggest a deficit in object identification and/or naming selection. It might be premature to conclude that children with PLI show normal semantic abilities. The results are largely consistent with a general language delay; however, there is also some evidence of a qualitative difference between both groups.

    1999-01-01

    The aim of this study was to assess whether potential differences in costs for diagnostic procedures and treatment of pulmonary embolism (PE) among European and U. S. hospitals alter the optimal cost-effective diagnostic strategy for PE. A standardized questionnaire was used to obtain cost data for the diagnosis and treatment of PE in participating European and U. S. hospitals. Costs for diagnostic tests and treatment of PE were then calculated in a standardized manner for all participating hospitals, from the hospital perspective. Costs were used in an existing cost-effectiveness analysis (CEA) model to determine the most cost-effective diagnostic strategy in participating hospitals. There were considerable differences in costs for diagnostic and therapeutic procedures for PE among the participating centers. These differences, however, did not affect the most cost-effective strategy based on incremental cost-effectiveness. In all hospitals the most cost-effective strategy appeared to be ultrasound followed by helical CT. International differences in cost of diagnostic and therapeutic procedures certainly exist and should be considered before applying a published CEA. Nevertheless, despite these cost differences, the diagnostic strategy for PE of ultrasound followed by helical CT appears most cost-effective. (orig.)

    Mean or maximal intima-media thickness (IMT) is commonly used as surrogate endpoint in intervention studies. However, the effect of normalization by surrounding or median IMT or by diameter is unknown. In addition, it is unclear whether IMT inhomogeneity is a useful predictor beyond common wall parameters like maximal wall thickness, either absolute or normalized to IMT or lumen size. We investigated the interrelationship of common carotid artery (CCA) thickness parameters and their association with the ipsilateral internal carotid artery (ICA) stenosis degree. CCA thickness parameters were extracted by edge detection applied to ultrasound B-mode recordings of 240 patients. Degree of ICA stenosis was determined from CT angiography. Normalization of maximal CCA wall thickness to median IMT leads to large variations. Higher CCA thickness parameter values are associated with a higher degree of ipsilateral ICA stenosis (p risk marker for having moderate ipsilateral ICA stenosis (>50%), 55 arteries (15%) are reclassified to another risk category. It is more reasonable to normalize maximal wall thickness to end-diastolic diameter rather than to IMT, affecting risk classification and suggesting modification of the Mannheim criteria.

  12. Fashion pictures and women pictures in French women magazine. Normatives parades or strategic masquerade?

    Directory of Open Access Journals (Sweden)

    Justine MARILLONNET

    2014-12-01

    Full Text Available This article proposes to study the fashion pictures within a representative sample of French women magazines. Based on the method of “sémiologie des indices”, used to analyze a corpus of woman’s body and fashion staged, this paper addresses the issue of new functions granted to the stereotyping process. Starting to the assumption of a contract between audience and media, this analysis shows that the gender stereotype may be prescribed, up to a caricature of the womanhood, to the female readers identified as co-producers of the media discourse. Demonstrating both the co-existence of a plurality of gender representations in its pictures and their variability, this work proposes the concept of strategic masquerade to apprehend the possible new functions for the process of gender stereotyping in media.

    Abstract (E: We investigate whether people use a narrative/story schema to organize visual information in figurative isolated pictures representing a "pregnant moment", and, if so, how they do this.  The participants in our study were asked to freely describe pictures that depict some event. Their descriptions were analyzed according to a system of categories developed especially for examining the use of an elaborated narrative organization. The findings support the hypothesis that observers use elaborated narrative organization that goes beyond mere temporal and causal organization (including, e.g., exposition, complication, resolution. Furthermore, the findings suggest that this elaborative narrative organization sometimes dominates the visual organization of the pictures.

    2000-06-01

    In three experiments, the nature of the representations involved in written picture naming and the time course of their activation were investigated. French participants had to produce picture names while hearing distractors. In Experiment 1, distractors semantically related to the picture names yielded a semantic interference effect when a stimulus onset asynchrony (SOA) of--150 msec, but not when a SOA of 0 msec, was used, in both spoken and written picture naming. Experiment 2 showed that the semantic interference effect was not located at the conceptual level. In Experiment 3, participants wrote down picture names while hearing semantically related, phonologically related, both semantically and phonologically related, or unrelated distractors, presented at both SOAs. A semantic interference effect was obtained with phonologically unrelated distractors but was eliminated with phonologically related distractors. Facilitatory effects of phonologically related distractors were found at both SOAs. The implications of the findings for written picture naming are discussed.

    Individuals with cocaine use disorder (CUD) chose cocaine over nondrug rewards. In two newly designed laboratory tasks with pictures, we document this modified choice outside of a cocaine administration paradigm. Choice for viewing cocaine, pleasant, unpleasant, or neutral pictures-under explicit contingencies (choice made between two fully visible side-by-side images) and under more implicit contingencies (selections made between pictures hidden under flipped-over cards)-was examined in 20 CUD and 20 matched healthy control subjects. Subjects also provided self-reported ratings of each picture's pleasantness and arousal. Under both contingencies, CUD subjects chose to view more cocaine pictures than control subjects, group differences that were not fully explained by the self-reported picture ratings. Furthermore, whereas CUD subjects choice for viewing cocaine pictures exceeded choice for viewing unpleasant pictures (but did not exceed choice for viewing pleasant pictures, in contrast to their self-reported ratings), healthy control subjects avoided viewing cocaine pictures as frequently as, or even more than, unpleasant pictures. Finally, CUD subjects with the most cocaine viewing selections, even when directly compared with selections of the pleasant pictures, also reported the most frequent recent cocaine use. Enhanced drug-related choice in cocaine addiction can be demonstrated even for nonpharmacologic (pictorial) stimuli. This choice, which is modulated by alternative stimuli, partly transcends self-reports (possibly indicative of a disconnect in cocaine addiction between self-reports and objective behavior) to provide an objective marker of addiction severity. Neuroimaging studies are needed to establish the neural underpinnings of such enhanced cocaine-related choice.

    A recent study indicated that amnesic patients have difficulties not only in describing past and imagined scenarios, but also in describing pictures that are in full view. This finding suggests that impaired memory hampers descriptions of scenarios more broadly. However, no such impairment in picture description in amnesic patients was observed in a related study. One key methodological difference between these studies was the complexity of the pictures to be described, hinting that group differences might be marked only if pictures are sufficiently complex to tax aspects of memory. To test this complexity hypothesis, we examined whether differences in picture description between amnesic patients and controls increase with increasing picture complexity. As in previous studies, we also assessed our participants' ability to describe imagined scenarios. Amnesic patients reported significantly fewer elements than did controls when describing pictures and imagined scenarios. The group difference in picture description was significantly larger for complex than for simple pictures. Although variations in lesion sites might have accounted for the aforementioned cross-study differences in picture description in amnesic patients, our results suggest that, at least in amnesic patients with extramedial temporal lobe lesions, the complexity of pictures can determine whether or not a (substantial) picture-description deficit is observed. We interpret these findings in terms of a narrative-construction deficit. We hypothesize that, whereas brief narrative can be constructed via nonmemory cognitive processes, the construction of more detailed narrative depends upon intact functioning of a temporary memory system, such as the episodic buffer.

    This study investigates age of acquisition (AoA) and word frequency effects in both spoken and written picture naming. In the first two experiments, reliable AoA effects on object naming speed, with objective word frequency controlled for, were found in both spoken (Experiment 1) and written picture naming (Experiment 2). In contrast, no reliable objective word frequency effects were observed on naming speed, with AoA controlled for, in either spoken (Experiment 3) or written (Experiment 4) picture naming. The implications of the findings for written picture naming are briefly discussed.

    2002-01-01

    We have taken, in October 1981, 20.000 pictures of proton-proton interactions at 5 GeV/c in order to get some clean elastic events which can be easily studied by high school students. The purpose is to illustrate, by actual measurements of these real events, some basic concepts of relativistic mechanisms. This experiment will be an extension of our previous one, performed with HBC 2m events taken at 2 GeV/c. In 1980, all french lycees were provided with large size reproduction of HBC 2m events. Before distribution they were carefully selected and severe kinematical cuts were made. The students measured track curvatures by template, and checked the necessity and the validity of relativistic mechanics by computing the energy balance using non-relativistic and relativistic formulae. No practical problems have been encountered during this experiment and the pedagogical results are encouraging. This new sample of events will be interesting because they are relativistic than the old ones although with the same curv...

    Drummond, K.J.

    1998-01-01

    The North American conventional gas resource base was reviewed and an explanation of how Canada's East coast fits into the overall picture was given. At 1996 year end, the total conventional ultimate natural gas resource base for North America was estimated to be 2,695 trillion cubic feet. The most important supply areas are Canada and the United States. Mexico and Alaska are expected to play only a minor role in the overall North American supply. Approximately half of the conventional gas estimated to exist in North America remains to be discovered. Only 78 per cent from the half that has been discovered has been produced, and only 22 per cent of it is remaining as reserves. Of the undiscovered natural gas resource, 38 per cent is in the frontier regions of Alaska and Canada. The growing importance of the East coast of North America as markets for natural gas was reviewed. The distribution of ultimate conventional marketable gas resources for Canada was described. The potential of the Western Canadian Sedimentary Basin (WCSB) and selected frontier areas were assessed. The report showed an undiscovered conventional marketable gas estimate of 122 trillion cubic feet for the WCSB and 107 trillion cubic feet for the Frontier areas. The two most significant areas of discovery in eastern Canada were considered to be the Hibernia oil field on the Grand Banks and the Venture gas field of the Scotian Shelf. 2 tabs., 7 figs

  5. Unexpected High Intragenomic Variation in Two of Three Major Pest Thrips Species Does Not Affect Ribosomal Internal Transcribed Spacer 2 (ITS2 Utility for Thrips Identification

    2017-10-01

    Full Text Available The mitochondrial cytochrome oxidase I gene (mtCO1 and the ribosomal internal transcribed spacer 2 region (ITS2 are among the most widely used molecular markers for insect taxonomic characterization. Three economically important species of thrips, Scirtothrips dorsalis, Thrips palmi, and Frankliniella occidentalis were selected to examine the extent of intragenomic variation within these two marker regions in the family Thripidae, and determine if this variation would affect the utility of markers in thrips molecular diagnostics. For each species, intragenomic (within individual variation and intergenomic (among individuals variation was assessed by cloning and sequencing PCR-amplified copies. Intergenomic variation was generally higher than intragenomic variation except in cases where intergenomic variation was very low, as in mtCO1 from S. dorsalis and F. occidentalis. Intragenomic variation was detected in both markers in all three of the thrips species, however, 2–3 times more intragenomic variation was observed for ITS2 than mtCO1 in both S. dorsalis and T. palmi. Furthermore, levels of intragenomic variation were low for both of the genes in F. occidentalis. In all of the three thrips species, no sex-based clustering of haplotypes was observed in either marker. Unexpected high intragenomic variation in ITS2 for two of three thrips species did not interfere with thrips diagnostics. However, caution should be taken in applying ITS2 to certain studies of S. dorsalis and T. palmi when high levels of intragenomic variation could be problematic or confounding. In such studies, mtCO1 may be a preferable marker. Possible reasons for discrepancies in intragenomic variation among genomic regions are discussed.

  6. Holographic picture of heavy vector meson melting

    The fraction of heavy vector mesons produced in a heavy ion collision, as compared to a proton-proton collision, serves as an important indication of the formation of a thermal medium, the quark-gluon plasma. This sort of analysis strongly depends on understanding the thermal effects of a medium like the plasma on the states of heavy mesons. In particular, it is crucial to know the temperature ranges where they undergo a thermal dissociation, or melting. AdS/QCD models are know to provide an important tool for the calculation of hadronic masses, but in general are not consistent with the observation that decay constants of heavy vector mesons decrease with excitation level. It has recently been shown that this problem can be overcome using a soft wall background and introducing an extra energy parameter, through the calculation of correlation functions at a finite position of anti-de Sitter space. This approach leads to the evaluation of masses and decay constants of S wave quarkonium states with just one flavor dependent and one flavor independent parameter. Here we extend this more realistic model to finite temperatures and analyze the thermal behavior of the states 1S, 2S and 3S of bottomonium and charmonium. The corresponding spectral function exhibits a consistent picture for the melting of the states where, for each flavor, the higher excitations melt at lower temperatures. We estimate for these six states the energy ranges in which the heavy vector mesons undergo a transition from a well-defined peak in the spectral function to complete melting in the thermal medium. A very clear distinction between the heavy flavors emerges, with the bottomonium state Υ(1S) surviving a deconfinement transition at temperatures much larger than the critical deconfinement temperature of the medium.

  12. The robustness of false memory for emotional pictures.

    Bessette-Symons, Brandy A

    2018-02-01

    Emotional material is commonly reported to be more accurately recognised; however, there is substantial evidence of increased false alarm rates (FAR) for emotional material and several reports of stronger influences on response bias than accuracy. This pattern is more frequently reported for words than pictures. Research on the mechanisms underlying bias differences has mostly focused on word lists under short retention intervals. This article presents four series of experiments examining recognition memory for emotional pictures while varying arousal and the control over the content of the pictures at two retention intervals, and one study measuring the relatedness of the series picture sets. Under the shorter retention interval, emotion increased false alarms and reduced accuracy. Under the longer retention interval emotion increased hit rates and FAR, resulting in reduced accuracy and/or bias. At both retention intervals, the pattern of valence effects differed based on the arousal associated with the picture sets. Emotional pictures were found to be more related than neutral pictures in each set; however, the influence of relatedness alone does not provide an adequate explanation for all emotional differences. The results demonstrate substantial emotional differences in picture recognition that vary based on valence, arousal and retention interval.

  2. Higher-order Multivariable Polynomial Regression to Estimate Human Affective States

    2016-03-01

    From direct observations, facial, vocal, gestural, physiological, and central nervous signals, estimating human affective states through computational models such as multivariate linear-regression analysis, support vector regression, and artificial neural network, have been proposed in the past decade. In these models, linear models are generally lack of precision because of ignoring intrinsic nonlinearities of complex psychophysiological processes; and nonlinear models commonly adopt complicated algorithms. To improve accuracy and simplify model, we introduce a new computational modeling method named as higher-order multivariable polynomial regression to estimate human affective states. The study employs standardized pictures in the International Affective Picture System to induce thirty subjects’ affective states, and obtains pure affective patterns of skin conductance as input variables to the higher-order multivariable polynomial model for predicting affective valence and arousal. Experimental results show that our method is able to obtain efficient correlation coefficients of 0.98 and 0.96 for estimation of affective valence and arousal, respectively. Moreover, the method may provide certain indirect evidences that valence and arousal have their brain’s motivational circuit origins. Thus, the proposed method can serve as a novel one for efficiently estimating human affective states.

  3. Viewing preferences of rhesus monkeys related to memory for complex pictures, colours and faces.

    Wilson, F A; Goldman-Rakic, P S

    1994-01-31

    In order to determine the preferences of rhesus monkeys for visual stimuli, their eye movements were measured in response to presentations of complex pictures, fields of uniform colour, and of faces using the scleral search coil technique. The monkeys (n = 4) controlled both the onset and offset of the stimuli by the direction of their gaze. Each stimulus was presented 4 times, with 0 or 2, and 36 or 38 trials between successive presentations. Several trends were apparent in their scanning behaviour: (1) all 4 monkeys spent more time looking at pictures and faces compared to colour fields. As individuals, they differed in their overall propensity in looking at visual stimuli: monkeys that spent the most (or least) time looking at pictures spent the most (or least) time looking at colour fields. (2) Although the monkeys appeared to prefer pictures and faces to colour fields as measured by gaze duration, preferences for individual pictures, faces and colour fields were not evident. (3) Memory for recently presented stimuli substantially affected gaze duration which was significantly longer for the first compared to the second presentation of the pictures and faces, and memory was estimated to influence gaze duration over as many as 38 intervening trials. These effects were not significant in the case of colour fields. (4) There were no significant differences either in the average latencies to initiate eye movements or the number of saccades on the first and second presentations of pictures, colors or faces for the 4 monkeys. However, the average latencies to the first eye movement within a trial were longer for colour fields than for pictures for all 4 monkeys. Individual monkeys differed substantially in their mean latencies for the initiation of the first eye movement within a trial, which ranged from 235 ms to 414 ms in the two extreme cases. (5) At the presentation of faces, the monkeys tended to make saccades to major facial features, and only occasionally to

  6. Emotional sounds modulate early neural processing of emotional pictures

    Directory of Open Access Journals (Sweden)

    Antje B M Gerdes

    2013-10-01

    Full Text Available In our natural environment, emotional information is conveyed by converging visual and auditory information; multimodal integration is of utmost importance. In the laboratory, however, emotion researchers have mostly focused on the examination of unimodal stimuli. Few existing studies on multimodal emotion processing have focused on human communication such as the integration of facial and vocal expressions. Extending the concept of multimodality, the current study examines how the neural processing of emotional pictures is influenced by simultaneously presented sounds. Twenty pleasant, unpleasant, and neutral pictures of complex scenes were presented to 22 healthy participants. On the critical trials these pictures were paired with pleasant, unpleasant and neutral sounds. Sound presentation started 500 ms before picture onset and each stimulus presentation lasted for 2s. EEG was recorded from 64 channels and ERP analyses focused on the picture onset. In addition, valence, and arousal ratings were obtained. Previous findings for the neural processing of emotional pictures were replicated. Specifically, unpleasant compared to neutral pictures were associated with an increased parietal P200 and a more pronounced centroparietal late positive potential (LPP, independent of the accompanying sound valence. For audiovisual stimulation, increased parietal P100 and P200 were found in response to all pictures which were accompanied by unpleasant or pleasant sounds compared to pictures with neutral sounds. Most importantly, incongruent audiovisual pairs of unpleasant pictures and pleasant sounds enhanced parietal P100 and P200 compared to pairings with congruent sounds. Taken together, the present findings indicate that emotional sounds modulate early stages of visual processing and, therefore, provide an avenue by which multimodal experience may enhance perception.

The distribution of the data may have in some instances deviated somewhat from the underlying assumptions for the standard psychometric tests for normality. We did not conduct test-retest reliability. The factorial structure of the TEMPS-A shows good reliability and internal consistency. Although the superstructure is reminiscent of neuroticism-extraversion, within it are embedded discernible classical affective temperaments. A provocative finding is the high prevalence of cyclothymia in Hungarian males (6%), which is rather unique when compared with the other 10 countries studied to date. This finding, coupled with high male hyperthymia (5.4%), may explain the high lifetime prevalence of bipolar disorders reported from Hungary. Inter alia, our psychometric data along with the foregoing epidemiologic considerations, are very much in line with the cyclothymic-bipolar spectrum model proposed by the senior author [Akiskal, H.S., Djenderedjian, A.H., Rosenthal, R.H., Khani, M.K., 1977. Cyclothymic disorder: validating criteria for inclusion in the bipolar affective group. Am. J. Psychiatry 134, 1227-1233].

    In these days when there are rumors about medical radiation exposure, it is the greatest keyword which it was inflicted with to radioactive ray's worker to secure radiation exposure reduction. I assume International Atomic Energy Agency (IAEA) BSS (Basic Safety Standards) guidance level, the medical radiation exposure reduction targeted value by JART (Japan Association of Radiological Technologists) a reasonable standard and, besides, must be able to tie equality and high quality medical care to an offer of security for a patient by getting rid of a difference in each institution. In mammography that needs is high in cancer death rate high rank of a woman as a background, authorization engineer system and institution authorization system establish it with a made guideline by a mammography precision management central committee, and not only an offer of a high quality picture depicting a minute mental change caused by a disease but also consideration of radiation exposure with the photography is done. Radiation exposure dose of radioactivity reduction by operation of a picture is nominated for possibility in digital system, but that radiation exposure dose of radioactivity increase than S/F system is felt uneasy about because actually I aim at the institution authorization acquisition. Maintain the high quality picture and to consider radiation exposure reduction are real invisible patient care, and I report the picture quality and interrelation of radiation exposure, and also speak a consideration method of the picture of the always equal tolerance level/tolerance level of the radiation exposure that a gap is not over in each institution.

    Memory affects behavior by allowing events to be anticipated and goals to be planned based on previous experiences. Emotional memory, in particular, is thought to play a central role in behavior in general and in drinking behavior in particular. Alcohol intoxication has been shown to disrupt intentional, conscious memory, but not unintentional, implicit memory for neutral stimuli; however, its effects on emotional memory are not well understood. This study examined whether alcohol intoxication affected memory for emotionally valenced stimuli by testing explicit recall and implicit repetition priming of emotional picture cues. Participants were 36 young adults (21-24 years old, 16 women) who received an alcohol, placebo, or no-alcohol beverage. Both cue exposure and memory testing occurred after beverage consumption (i.e., during intoxication for the alcohol group). Alcohol intoxication impaired explicit recall of all cue types but did not impair implicit repetition priming. Emotionally negative and positive cues were more often recalled compared with neutral cues across all beverage groups, and emotionally negative cues demonstrated more priming than emotionally positive or neutral cues in all beverage groups. Alcohol intoxication disrupted effortful recall of all cues, although the relative memory advantage of emotionally valenced over-neutral stimuli remained even after drinking. The effects of alcohol on unintentional memory priming were not statistically significant, but the effects of emotionally negative cues were. Further research is needed to better understand alcohol intoxication and emotional valence effects on memory processes during implicit memory tasks and the possibility that negative mood facilitates memory priming of negative emotional stimuli.

  14. On discriminating and not discriminating between affect and representation.

    The topic involves two issues. They can be related either to different clinical pictures or to divergent opinions about the same clinical facts. But the above mentioned opposition can be found in Freud's work. Listening in analysis differentiates between situations where the distinction of affect and representation is blurred within the general frame of communication and others where this distinction imposes itself because of the critical or chronic character of the predominance of affect. Problems about the discrimination between affect and representation in the unconscious are elucidated in the light of their structural differences. The notion of the psychical representative of the drive announces the reference to the further notion of instinctual impulse. Later on, in Freud's theory, the notion of instinctual impulse has encompassed the distinction between affects and representation. Contemporary authors have, in their vast majority, chosen to refer preferably to object relationships. Nevertheless, the problems raised by Freud remain unanswered. It is with the clinical picture of borderline personality disorders that the lack of discrimination between affect and representation becomes evident. A detailed description is presented of the forms of transference where the irrepresentable prevails, accompanied by feelings of being overwhelmed, repetition compulsion, acting out and somatic reactions. In the countertransference, the affects of helplessness, despair and even the impossibility of grasping the meaning of the patient's communication are frequently met in the analyst. In these clinical pictures, intermediary formations, i.e. psychic organisations where primary processes structures the unconscious, are impaired. One is struck by the limitation of the capacities of representation and by the importance of phenomena related to negative hallucinations specially focused on thought processes, The communication is frequently self-contradictory, the transference

    Some individuals report problems during and after Internet sex engagement, such as missing sleep and forgetting appointments, which are associated with negative life consequences. One mechanism potentially leading to these kinds of problems is that sexual arousal during Internet sex might interfere with working memory (WM) capacity, resulting in a neglect of relevant environmental information and therefore disadvantageous decision making. In this study, 28 healthy individuals performed 4 experimental manipulations of a pictorial 4-back WM task with neutral, negative, positive, or pornographic stimuli. Participants also rated 100 pornographic pictures with respect to sexual arousal and indicated masturbation urges previous to and following pornographic picture presentation. Results revealed worse WM performance in the pornographic picture condition of the 4-back task compared with the three remaining picture conditions. Furthermore, hierarchical regression analysis indicated an explanation of variance of the sensitivity in the pornographic picture condition by the subjective rating of the pornographic pictures as well as by a moderation effect of masturbation urges. Results contribute to the view that indicators of sexual arousal due to pornographic picture processing interfere with WM performance. Findings are discussed with respect to Internet sex addiction because WM interference by addiction-related cues is well known from substance dependencies.

    Full Text Available AbstractPictures and film clips are widely used and accepted stimuli to elicit emotions. Based on theoretical arguments it is often assumed that the emotional effects of films exceed those of pictures, but to date this assumption has not been investigated directly. The aim of the present study was to compare pictures and films in terms of their capacity to induce emotions verified by means of explicit measures. Stimuli were (a single pictures presented for 6 s, (b a set of three consecutive pictures with emotionally congruent contents presented for 2 s each, (c short film clips with a duration of 6 s. A total of 144 participants rated their emotion and arousal states following stimulus presentation. Repeated-measures ANOVAs revealed that the film clips and 3-picture version were as effective as the classical 1-picture method to elicit positive emotions, however, modulation towards positive valence was little. Modulation toward negative valence was more effective in general. Film clips were less effective than pictorial stimuli in producing the corresponding emotion states (all p < .001 and were less arousing (all p ≤ .02. Possible reasons for these unexpected results are discussed.

    enshrined in the English language. The present article asserts and demonstrates by example that by creating the described type of dictionaries a basis can be laid for engaging the broader linguistic picture of the world in a whole new way, as their structure enables the drawing of clear semantic boundaries between and within the verbal fields of major concepts. These, in turn, can be used for creating maps, or rather atlases, initially of the smaller segments of linguistic pictures of the world, which may over time, and with enough methodological evolution, transform into larger-scale projects covering different languages, which arguably contains a hitherto unexplored potential for comparing them at a new systemic level, that of the structure and internal semantic delimitation of linguistic pictures of the world.

  20. Use of the Adult Attachment Projective Picture System in Psychodynamic Psychotherapy with a Severely Traumatized Patient

    2014-08-01

    Full Text Available The Adult Attachment Projective Picture System (AAP is a valid representational measure of internal representations of attachment based on the analysis of a set of free response picture stimuli designed to systematically activate the attachment system (George & West, 2012. The AAP provides a fruitful diagnostic tool for psychodynamic-oriented clinicians to identify attachment-based deficits and resources for an individual patient in therapy. This paper considers the use of the AAP with a traumatized patient in an inpatient setting and uses a case study to illustrate the components of the AAP that are particularly relevant to a psychodynamic conceptualization. The paper discusses also attachment-based recommendations for intervention.

    In the last few years picture analysis became a powerful technique for measurements of nuclear tracks in plastic detectors. For this purpose rather expensive commercial systems are available. Two inexpensive microprocessor based systems with different resolution were developed. The video pictures of particles seen through a microscope are digitized in real time and the picture analysis is done by software. The microscopes are equipped with stages driven by stepping motors, which are controlled by separate microprocessors. A PDP 11/03 supervises the operation of all microprocessors and stores the measured data on its mass storage devices. (author)

    The influence of nine variables on the latencies to write down or to speak aloud the names of pictures taken from Snodgrass and Vanderwart (1980) was investigated in French adults. The major determinants of both written and spoken picture naming latencies were image variability, image agreement and age of acquisition. To a lesser extent, name agreement was also found to have an impact in both production modes. The implications of the findings for theoretical views of both spoken and written picture naming are discussed.

    According to the body-specificity hypothesis, hearing action words creates body-specific mental simulations of the actions. Handedness should, therefore, affect mental simulations. Given that pictures of actions also evoke mental simulations and often accompany words to be learned, would pictures that mismatch the mental simulation of words negatively affect learning? We investigated effects of pictures with a left-handed, right-handed, or bimanual perspective on left- and right-handers' learning of object-manipulation words in an artificial language. Right-handers recalled fewer definitions of words learned with a corresponding left-handed-perspective picture than with a right-handed-perspective picture. For left-handers, there was no effect of perspective. These findings suggest that mismatches between pictures and mental simulations evoked by hearing action words can negatively affect right-handers' learning. Left-handers, who encounter the right-handed perspective frequently, could presumably overcome the lack of motor experience with visual experience and, therefore, not be influenced by picture perspective.

    2014-08-01

    Full Text Available It is important for journal editors to keep up to date with the changes happening in the international journal environment to ensure that their own publications remain current and meet international expectations. Dramatic changes have taken place in the journals environment during the last two decades, frequently driven by technology but also by increased global participation in scholarly and scientific research and concern about the commercial influence on dissemination of knowledge. Technical solutions have attempted to address the growth in research but have sometimes added to the tsunami of information and increased the need to manage quality. To this end experiments with the traditional quality control and dissemination systems have been attempted, but news of improvements are frequently overshadowed by alarms about ethical problems. There is particular concern about some of the new publishers who are not adhering to established quality control and ethical practices. Within a potentially fragmenting system, however, there are also emerging collaborative projects helping to knit together the different elements of the publishing landscape to improve quality, linkages and access.

  8. Reduction of high levels of internal radio-contamination by dietary intervention in residents of areas affected by the Fukushima Daiichi nuclear plant disaster: a case series.

    Masaharu Tsubokura

    Full Text Available Maintaining low levels of chronic internal contamination among residents in radiation-contaminated areas after a nuclear disaster is a great public health concern. However, the efficacy of reduction measures for individual internal contamination remains unknown. To reduce high levels of internal radiation exposure in a group of individuals exposed through environmental sources, we performed careful dietary intervention with identification of suspected contaminated foods, as part of mass voluntary radiation contamination screenings and counseling program in Minamisoma Municipal General Hospital and Hirata Central Hospital. From a total of 30,622 study participants, only 9 residents displayed internal cesium-137 (Cs-137 levels of more than 50 Bq/kg. The median level of internal Cs-137 contamination in these residents at the initial screening was 4,830 Bq/body (range: 2,130-15,918 Bq/body and 69.6 Bq/kg (range: 50.7-216.3 Bq/kg. All these residents with high levels of internal contamination consumed homegrown produce without radiation inspection, and often collected mushrooms in the wild or cultivated them on bed-logs in their homes. They were advised to consume distributed food mainly and to refrain from consuming potentially contaminated foods without radiation inspection and local produces under shipment restrictions such as mushrooms, mountain vegetables, and meat of wild life. A few months after the intervention, re-examination of Cs levels revealed remarkable reduction of internal contamination in all residents. Although the levels of internal radiation exposure appear to be minimal amongst most residents in Fukushima, a subset of the population, who unknowingly consumed highly contaminated foodstuffs, experienced high levels of internal contamination. There seem to be similarities in dietary preferences amongst residents with high internal contamination levels, and intervention based on pre- and post-test counseling and dietary advice from

  9. Edge detection of barium-filled stomach picture by one-dimensional collation method

    1983-01-01

    The method for the contour edge detection of barium- filled stomach pictures by X-ray for the automatic screening is described using computer technique. It is necessary for the automatic screening of barium- filling pictures to detect accurately the outline of stomachs because the analysis of repletion pictures is performed by checking the disorder of marginal contours and abnormal stomach shapes. However, the detection of the coutour lines is difficult to be successful for the reason that the contrast of stomach pictures to background is low, a stomach is not necessarily filled completely with barium and the shadow of barium flowing into intestines is superimposed on stomach images and the shading is likely to occur. The engineering processing against these problems is not yet solved. In order to reduce the noise due to differential operator, the proposed method determines the boundary of a thing generally by the threshold value of density, and defines the edge of the thing from the differential waveform of density in the vicinity of the boundary. In addition, the method corrects the detection error caused by the local nonconformity of parameters by comparing the edges between the adjacent lines. As a result, in spite of its simple algorithm, the edges with good continuity and less noise can be detected, and the method is not much affected by shading. This method was found to be applicable to the images of others than stomachs. The extraction of the contour of barium- filling pictures requires the high level recognition processing instead of the simple conditioning. (Wakatsuki, Y.)

  10. PIV pictures of stream field predict haemolysis index of centrifugal pump with streamlined impeller.

    Previously it has been found by pump haemolysis testing that the flow rate has a remarkable effect on index of haemolysis (IH), while pressure head does not affect IH. Recent investigation with particle image velocimetry (PIV) technology has demonstrated that IH is directly related to the flow pattern of stream field in impeller vane channels. PIV is a visible approach showing the real flow status in the pump. The different positions of a tracer particle in two PIV pictures taken at 20 micros intervals decide the velocity value and direction. The velocity vectors of many particles draw the flow pattern of the stream field. The same pictures are taken at 2, 4 and 6 l min(-1) flow rates while the pressure head is kept unchanged at 100 mmHg; then the pictures are taken at 4 l min(-1) flow with different pressure heads of 80, 100 and 120 mmHg. Results reveal that the flow rate of 4 l min(-1) (IH = 0.030) has the best stream field, and neither turbulence nor separation can be seen. In other flow rates (IH: 0.048 - 0.082), there is obviously second flow. Meanwhile, no significant difference can be seen among the PIV pictures of different pressure heads pumped, which agrees with the results of haemolysis testing showing that pressure has no effect on pump haemolysis. It may be concluded that the haemolysis property of a centrifugal pump can be assessed approximately by PIV pictures, which are much easier to take than haemolysis tests.

    A system for objectively scoring the magazine picture collage was developed and applied to the collages of 12 psychiatric inpatients and 12 paired controls. As a group, the patient collages had fewer cuttings, tended to lack an overall balance and central theme, and contained fewer pictures of people and more of animals. The results are consistent with those reported by other researchers as well as with general clinical experience, and as such, lend support to the construct validity of the scoring system.

    Full Text Available We are living in a world surrounded by images; everywhere we go we are overwhelmed by commercials, plasma screens, posters etc. We get lost in these “perfect” pictures, we dream about that perfect body, that perfect sunny holiday and that perfectly happy family. We spend time consuming those pictures, but we don’t spend time to see ourselves as we are, to discover our inner self. But, can we discover ourselves in pictures? I believe so, but only when the pictures are created and not consumed. When pictures are created, creation becomes therapy and the result of the work becomes a means of self discovery and exploration. There are many examples of artists using different media like: sculpture, painting, installation, video that create pictures making use of their own body/face, of their own lives, of their own dreams, hallucinations or obsessions. This is a good way to bring their problems out of the subconscious, to use them in a creative and playful way, to visualize them and to share them with the world. The paper intends to explore the possibilities of self discovery through creating pictures, and in what proportion this activity can become therapy, art or both. The analysis will focus on the possibilities of accepting and comprehending oneself by taking pictures of oneself; on how genuine self-portraits can overcome the individual conflict between who one actually is, what one believes people’s perceptions of oneself are and who one thinks people want one to be in order to be accepted or even successful.

    How incretins regulate presence of their receptors at the cell surface and their activity is of paramount importance for the development of therapeutic strategies targeting these receptors. We have studied internalization of the human Glucose-Insulinotropic Polypeptide receptor (GIPR). GIP stimulated rapid robust internalization of the GIPR, the major part being directed to lysosomes. GIPR internalization involved mainly clathrin-coated pits, AP-2 and dynamin. However, neither GIPR C-terminal region nor β-arrestin1/2 was required. Finally, N-acetyl-GIP recognized as a dipeptidyl-IV resistant analogue, fully stimulated cAMP production with a ∼15-fold lower potency than GIP and weakly stimulated GIPR internalization and desensitization of cAMP response. Furthermore, docking N-acetyl-GIP in the binding site of modeled GIPR showed slighter interactions with residues of helices 6 and 7 of GIPR compared to GIP. Therefore, incomplete or partial activity of N-acetyl-GIP on signaling involved in GIPR desensitization and internalization contributes to the enhanced incretin activity of this peptide.

    Children with AD/HD exhibit two disparate areas of difficulty: disrupted interactions with parents and significant problems in story comprehension. This study links these two difficulties by examining parent-child joint picture-book reading to determine whether there were diagnostic group differences in parent and child storytelling. Parents of 25 children with ADHD and 39 comparison children (mean age = 7.5 years) told their children a story based on a wordless picture-book, and children then retold the story to an examiner from memory. Parents in both groups told stories of similar length and complexity and demonstrated similar affective and responsive quality. The length of the child's retell of the parent's story did not differ across groups but children with ADHD included fewer goal-based events. RESULTS are discussed in terms of implications for enhancing the quality and frequency of parent-child storytelling among children with ADHD.

    We examined the role of mental imagery skills on story comprehension in 150 fifth graders (10- to 12-year-olds), when reading a narrative book chapter with alternating words and pictures (i.e., text blocks were alternated by one- or two-page picture spreads). A parallel group design was used, in which we compared our experimental book version, in which pictures were used to replace parts of the corresponding text, to two control versions, i.e., a text-only version and a version with the full story text and all pictures. Analyses showed an interaction between mental imagery and book version: children with higher mental imagery skills outperformed children with lower mental imagery skills on story comprehension after reading the experimental narrative. This was not the case for both control conditions. This suggests that children's mental imagery skills significantly contributed to the mental representation of the story that they created, by successfully integrating information from both words and pictures. The results emphasize the importance of mental imagery skills for explaining individual variability in reading development. Implications for educational practice are that we should find effective ways to instruct children how to "read" pictures and how to develop and use their mental imagery skills. This will probably contribute to their mental models and therefore their story comprehension.

    The present study investigated whether naming would facilitate infants’ transfer of information from picture books to the real world. Eighteen- and 21-month-olds learned a novel label for a novel object depicted in a picture book. Infants then saw a second picture book in which an adult demonstrated how to elicit the object’s non-obvious property. Accompanying narration described the pictures using the object’s newly learnt label. Infants were subsequently tested with the real-world object depicted in the book, as well as a different-color exemplar. Infants’ performance on the test trials was compared with that of infants in a no label condition. When presented with the exact object depicted in the picture book, 21-month-olds were significantly more likely to attempt to elicit the object’s non-obvious property than were 18-month-olds. Learning the object’s label before learning about the object’s hidden property did not improve 18-month-olds’ performance. At 21-months, the number of infants in the label condition who attempted to elicit the real-world object’s non-obvious property was greater than would be predicted by chance, but the number of infants in the no label condition was not. Neither age group nor label condition predicted test performance for the different-color exemplar. The findings are discussed in relation to infants’ learning and transfer from picture books.

    Full Text Available Abstract Background Germ line mutations in mismatch repair genes underlie Lynch syndrome and predispose carriers for colorectal carcinoma and malignancies in many other organ systems. Case presentation A large Lynch syndrome family with 15 affected family members and involvement in 7 organs is reported. It illustrates a lack of awareness and knowledge about this hereditary tumor syndrome among doctors as well as patients. None of the described family members underwent presymptomatic screening on the basis of the family history. Conclusion Hereditary features, like young age at diagnosis, multiple tumors in multiple organs and a positive family history, should lead to timely referral of suspected cases for genetic counseling and diagnostics. For Lynch syndrome, these features can be found in the Amsterdam and Bethesda criteria. Subsequently, early identification of mutation carriers might have diminished, at least in part, the high and early morbidity and mortality observed in this family.

    2014-08-01

    Saudi Arabia is the largest country in the region and it is the largest oil producing country in the world. It is one of the few countries in the world which was not affected significantly by the global economic crisis. Health care spending is led mainly by governmental expenditure. Private sector share of the health care services is supported by the government and increasing. The demands for pharmaceutical products, medical devices and health care services is fueled by the rapidly growing population and the wide spread of chronic diseases. Publications and expertise in the field of pharmacoeconomics is scarce within the country. There is an urgent need to establish a national center for pharmacoeconomics to lead the country efforts in controlling the cost of health care services. Such a center is needed to promote pharmacoeconomics research and train health care professionals in this field.

    Few researchers have attempted to examine the mechanisms through which HIV-related stigma in the community is processed and experienced at an individual level by people living with HIV. We examined how the effects of perceived HIV stigma in the community on health outcomes for people living with HIV are mediated by internalized stigma and anticipated stigma. Participants (N = 203) from an HIV clinic completed self-report measures and their clinical data were obtained from medical records. Results suggested that the association between perceived community stigma and affective, cognitive, and mental health outcomes (self-esteem, depressive symptoms, avoidance coping, self-blame) are mediated by internalized stigma. Furthermore, a serial mediation model suggested that perceived community stigma leads to internalized stigma, which leads to anticipated community stigma, which in turn leads to lower medication adherence. The associations between perceived community stigma and interpersonal outcomes (social support, trust in physicians) were mediated by internalized stigma and anticipated stigma, again in a serial fashion (perceived community stigma leads to internalized stigma, which leads to anticipated stigma, which in turn leads to interpersonal outcomes). These results suggest that perceived HIV-related stigma in the community may cause people living with HIV to internalize stigma and anticipate stigmatizing experiences, resulting in adverse health and psychosocial outcomes-information that can be used to shape interventions.

  14. Resolving the Aerosol Piece of the Global Climate Picture

    Kahn, R. A.

    2017-12-01

    Factors affecting our ability to calculate climate forcing and estimate model predictive skill include direct radiative effects of aerosols and their indirect effects on clouds. Several decades of Earth-observing satellite observations have produced a global aerosol column-amount (AOD) record, but an aerosol microphysical property record required for climate and many air quality applications is lacking. Surface-based photometers offer qualitative aerosol-type classification, and several space-based instruments map aerosol air-mass types under favorable conditions. However, aerosol hygroscopicity, mass extinction efficiency (MEE), and quantitative light absorption, must be obtained from in situ measurements. Completing the aerosol piece of the climate picture requires three elements: (1) continuing global AOD and qualitative type mapping from space-based, multi-angle imagers and aerosol vertical distribution from near-source stereo imaging and downwind lidar, (2) systematic, quantitative in situ observations of particle properties unobtainable from space, and (3) continuing transport modeling to connect observations to sources, and extrapolate limited sampling in space and time. At present, the biggest challenges to producing the needed aerosol data record are: filling gaps in particle property observations, maintaining global observing capabilities, and putting the pieces together. Obtaining the PDFs of key particle properties, adequately sampled, is now the leading observational deficiency. One simplifying factor is that, for a given aerosol source and season, aerosol amounts often vary, but particle properties tend to be repeatable. SAM-CAAM (Systematic Aircraft Measurements to Characterize Aerosol Air Masses), a modest aircraft payload deployed frequently could fill this gap, adding value to the entire satellite data record, improving aerosol property assumptions in retrieval algorithms, and providing MEEs to translate between remote-sensing optical constraints

  15. Tet38 Efflux Pump Affects Staphylococcus aureus Internalization by Epithelial Cells through Interaction with CD36 and Contributes to Bacterial Escape from Acidic and Nonacidic Phagolysosomes.

    We previously reported that the Tet38 efflux pump is involved in internalization of Staphylococcus aureus by A549 lung epithelial cells. A lack of tet38 reduced bacterial uptake by A549 cells to 36% of that of the parental strain RN6390. Using invasion assays coupled with confocal microscopy imaging, we studied the host cell receptor(s) responsible for bacterial uptake via interaction with Tet38. We also assessed the ability of S. aureus to survive following alkalinization of the phagolysosomes by chloroquine. Antibody to the scavenger receptor CD36 reduced the internalization of S. aureus RN6390 by A549 cells, but the dependence on CD36 was reduced in QT7 tet38, suggesting that an interaction between Tet38 and CD36 contributed to S. aureus internalization. Following fusion of the S. aureus-associated endosomes with lysosomes, alkalinization of the acidic environment with chloroquine led to a rapid increase in the number of S. aureus RN6390 bacteria in the cytosol, followed by a decrease shortly thereafter. This effect of chloroquine was not seen in the absence of intact Tet38 in mutant QT7. These data taken together suggest that Tet38 plays a role both in bacterial internalization via interaction with CD36 and in bacterial escape from the phagolysosomes.

  16. Diplomatic and political problems affecting the formulation and implementation of an international protocol for activities following the detection of a signal from extraterrestrial intelligence

    Science.gov (United States)

    Goodman, Allan E.

    This paper is based on interviews with scientists and national space policy makers on what such a protocol should contain and their reactions to the draft of one proposed by the author at the 15th Review Meeting on the Search for Extraterrestrial Intelligence, held during the XXXVII International Astronautical Congress (1986). The key arguments against formulating a post-detection protocol are whether such advance work is necessary or practical, the implications it would have for national sovereignty and the wisdom of disseminating information about SETI research in general to the public. While such problems could be major obstacles to implementing a post-detection protocol, they are not sufficient grounds to discourage efforts to develop one. The principal operational problem will be to find an appropriate and effective international consultative body to which the discovery of extraterrestrial intelligence signals and plans for analyzing and responding to them can be referred. The paper recommends establishment of a new consultative organization which would be chartered under the auspices of the International Astronautical Union or other appropriate international scientific body.

    Purpose: To establish an understanding of radiography education across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiography Societies (EFRS). Method: An online survey was developed to ascertain data on: curricula, duration, credit load, accreditation requirements, staff qualifications, staff and student exchange opportunities, and availability of postgraduate programmes. Responses were identifiable in terms of educational institution and country. All 46 affiliated educational institutions were invited to participate in the survey. Descriptive and thematic analyses are reported. Results: A response rate of 89.1% (n = 41) was achieved from educational institutions representing 21 countries. The majority of institutions (63.4%) offer a combined Medical Imaging, Radiotherapy and Nuclear Medicine programme; dedicated Medical Imaging programmes are offered by 14 institutions (34.2%); dedicated Radiotherapy programme by one institution (2.4%), and a dedicated Nuclear Medicine programme by only three institutions (6.5%). The Bologna (Bachelor) cycle has been adopted by 90.2% of responding institutions. The majority of institutions (53.7%) indicated programmes of 3 years in duration, others stated 3.5–4 years. Only 14.6% of institutions require ‘International Level’ accreditation for the Bachelors radiography programme. Postgraduate programmes were not offered by 26.8% of institutions and a deficit in Doctoral status for radiography educators was identified. Conclusions: The Bologna (Bachelor) cycle for radiography education has been adopted across the majority of institutions, however, full alignment remains a priority. Postgraduate radiography education opportunities across Europe appear to be insufficient and further investigation of radiography accreditation processes is justified to ensure harmonisation of practice. - Highlights: • The majority of institutions are compliant with the

    The processing disadvantage of verbs compared to nouns and the greater vulnerability of verbs in brain damage have been ascribed to greater processing demands of morpho-syntactical or/and semantic properties for verbs, or/and visual complexity in picture-naming studies. Using picture naming, the current functional magnetic resonance imaging study examined the neural substrates underlying the semantic distinction between nouns and verbs. Under forced (externally-elicited) or free (internally-motivated) conditions, participants named a set of pictorial stimuli as objects or actions performed on/with the objects in Chinese. Use of a language with impoverished inflectional morphology (i.e., Chinese) and the same set of pictures for naming objects and actions allows for the control of both morpho-syntactical and visual confounds. The results revealed specific neural correlates for action verbs in the cortical-subcortical motor system, irrespective of the naming conditions. Plausible accounts for the motor aspects of action-verb processing were interpreted basically on a semantic basis. Copyright © 2018 Elsevier Inc. All rights reserved.

    With the proliferation of rare disease registries, there is a need for registries to undergo an assessment of their quality against agreed standards to ensure their long-term sustainability and acceptability.This study was performed to evaluate the I-DSD and I-CAH Registries and identify their strengths and weaknesses. The design and operational aspects of the registries were evaluated against published quality indicators. Additional criteria included the level of activity, international acceptability of the registries and their use for research. The design of the I-DSD and I-CAH Registries provides them with the ability to perform multiple studies and meet the standards for data elements, data sources and eligibility criteria. The registries follow the standards for data security, governance, ethical and legal issues, sustainability and communication of activities. The data have a high degree of validity, consistency and accuracy and the completeness is maximal for specific conditions such as androgen insensitivity syndrome and congenital adrenal hyperplasia. In terms of research output, the external validity is strong but the wide variety of cases needs further review. The internal validity of data was condition specific and highest for conditions such as congenital adrenal hyperplasia. The shift of the registry from a European registry to an international registry and the creation of a discrete but linked CAH registry increased the number of users and stakeholders as well as the international acceptability of both registries. The I-DSD and I-CAH registries comply with the standards set by expert organisations. Recent modifications in their operation have allowed the registries to increase their user acceptability.

    Internalization of human pathogens in edible parts of vegetables eaten raw is a major concern, since once internalized they are protected from sanitizing treatments. In this study, we examined the invasion of gfp-labelled Escherichia coli O157:H7 into intact and biotically (infection with Xanthomonas campestris/Pseudomonas syringae) and abiotically (grating with silicon carbide) damaged leaves of wild rocket (Diplotaxis tenuifolia) and Swiss chard (Beta vulgaris subsp. cicla) using laser scanning confocal microscopy. Bacterial cells were found in internal locations of the tissue, irrespective of tissue health status. Contaminated leaf sections of biotically and abiotically damaged wild rocket leaves showed higher susceptibility to microbial invasion, while the pathogen was internalized in greater numbers into intact Swiss chard leaf sections when abiotically, but not biotically, damaged. The greatest differences were observed between the plant species; after surface sanitization, E. coli O157:H7 was still detected in wild rocket leaves, but not in Swiss chard leaves. Contamination of leafy vegetables with Escherichia coli O157:H7 is a growing problem, as reported outbreaks are increasing. However, establishment of this human pathogen in the phyllosphere is not completely understood. Using laser scanning confocal microscopy, we demonstrated that E. coli O157:H7gfp+ can invade plant tissue of Swiss chard and wild rocket leaves and that the bacterium is more sensitive to surface sanitization of Swiss chard leaves. Damage to leaf tissue promoted leaf invasion, but the nature of the damage (abiotic or biotic) and plant species had an impact. © 2017 The Society for Applied Microbiology.

    The ability of animals to visually memorize and categorize a large number of pictures is well established. Determining the kinds of information animals use to accomplish these goals has been more difficult. This experiment examined the contribution of spatial frequency information to picture memorization by pigeons. A series of grayscale pictures were notch-filtered to eliminate different portions of the spatial frequency spectrum of memorized pictures. The results indicated that the higher spatial frequencies in the pictures were most important to accurate recognition, suggesting that the detection of fine detail at the high range of pigeon visual acuity was a critical component to their memorized representations. Subsequent tests with band-pass and hybrid conflict stimuli confirmed this conclusion. It is suggested that cognitive and task demands may determine how spatial frequency is used by pigeons, with higher frequencies more important to item memorization, while lower spatial frequencies may contribute to categorization in other types of discrimination tasks.

    2008-01-01

    This study investigated the relationship between semantic and episodic memory as they support lexical access by healthy younger and older adults and individuals with Alzheimer's disease (AD). In particular, we were interested in examining the pattern of semantic and episodic memory declines in AD (i.e., word-finding difficulty and impaired recent memory) vis-à-vis more preserved remote memories. We administered a picture naming task in which the episodic period of the pictures and whether the pictured items were unique to one period or commonly used across periods were varied. Groups of younger adults (N=40), healthy older adults (N=20) and older adults with AD (N=18) were asked to name drawings of objects in four conditions: dated unique, contemporary unique, dated common, and contemporary common. The results indicated that all participants named items that were common to both episodic periods more successfully than items unique to one period. An interaction was observed such that the healthy older and AD groups were more successful in retrieving names of objects presented in the dated compared to contemporary unique conditions, whereas the younger adults showed the reverse pattern. These results indicate that naming ability is affected both by the cumulative frequency of using an item over a lifetime and by when an item was first acquired. The findings support a theoretical stance which proposes an enduring reciprocal link between semantic and episodic memory. This theoretical relationship has practical implications for the development of intervention strategies when interacting with persons who have AD.

    Although the effect of context on cognition is observable across cultures, preliminary findings suggest that when asked to judge the emotion of a target model's facial expression, East Asians are more likely than their North American counterparts to be influenced by the facial expressions of surrounding others (Masuda et al., 2008b). Cultural psychologists discuss this cultural variation in affective emotional context under the rubric of holistic vs. analytic thought, independent vs. interdependent self-construals, and socially disengaged vs. socially engaged emotion (e.g., Mesquita and Markus, 2004). We demonstrate that this effect is generalizable even when (1) photos of real facial emotions are used, (2) the saliency of the target model's emotion is attenuated, and (3) a specific amount of observation time is allocated. We further demonstrate that the experience plays an important role in producing cultural variations in the affective context effect on cognition.

    Full Text Available Authors introduce a new instrument, which they developed for measuring separation and individuation process and attachment in adolescence and adulthood. The Picture Test of Separation and Individuation (PTSI is a semi–projective test. It consists of various pictures, which represent relationships with significant others. PTSI is divided into three subtests: Relationship with Mother, Relationship with Father and Attachment. In a preliminary research on a sample of college and university students authors studied basic properties of the test. The results of the research indicate that PTSI is consistent with theoretical background, has good sensitivity and is economical. The Picture Test of Separation and Individuation enables quick but complex insight into individual's relationships with significant others as well as into his/her stage of separation and individuation process. Considering satisfying results of pilot study, authors suggest further research for validation of the test.

    2016-02-07

    This article describes a field experiment with a pretest-posttest control group design which investigated the potential of reading picture books to children for supporting their mathematical understanding. The study involved 384 children from 18 kindergarten classes in 18 schools in the Netherlands. During three months, the children in the nine experimental classes were read picture books. Data analysis revealed that, when controlled for relevant covariates, the picture book reading programme had a positive effect ( d  = .13) on kindergartners' mathematics performance as measured by a project test containing items on number, measurement and geometry. Compared to the increase from pretest to posttest in the control group, the increase in the experimental group was 22% larger. No significant differential intervention effects were found between subgroups based on kindergarten year, age, home language, socio-economic status and mathematics and language ability, but a significant intervention effect was found for girls and not for boys.

    Picture books can influence how children perceive people of different backgrounds, including people with disabilities whose cultures differ from their own. Researchers have examined the portrayal of multicultural characters with disabilities in children's literature. However, few have specifically considered the portrayal of deaf characters, despite increased inclusion of deaf characters in children's literature over the past two decades. The present study analyzed the portrayal of deaf characters in picture books for children ages 4-8 years. A content analysis of 20 children's picture books was conducted in which the books were analyzed for messages linked to pathological and cultural categories. Results indicated that these books did not portray Deaf characters from a cultural perspective but, rather, highlighted aspects of deafness as a medical condition, one that requires fixing and that perpetuates stereotypes of deafness as a disability.

    Although the relationship between "mere exposure" and attitude enhancement is well established in the adult domain, there has been little similar work with children. This article examines whether toddlers' visual attention toward pictures of foods can be enhanced by repeated visual exposure to pictures of foods in a parent-administered picture book. We describe three studies that explored the number and nature of exposures required to elicit positive visual preferences for stimuli and the extent to which induced preferences generalize to other similar items. Results show that positive preferences for stimuli are easily and reliably induced in children and, importantly, that this effect of exposure is not restricted to the exposed stimulus per se but also applies to new representations of the exposed item.

    In line with the Theory of Event Coding (Hommel et al., 2001a), action planning has been shown to affect perceptual processing - an effect that has been attributed to a so-called intentional weighting mechanism (Wykowska et al., 2009; Memelink and Hommel, 2012), whose functional role is to provide information for open parameters of online action adjustment (Hommel, 2010). The aim of this study was to test whether different types of action representations induce intentional weighting to various degrees. To meet this aim, we introduced a paradigm in which participants performed a visual search task while preparing to grasp or to point. The to-be performed movement was signaled either by a picture of a required action or a word cue. We reasoned that picture cues might trigger a more concrete action representation that would be more likely to activate the intentional weighting of perceptual dimensions that provide information for online action control. In contrast, word cues were expected to trigger a more abstract action representation that would be less likely to induce intentional weighting. In two experiments, preparing for an action facilitated the processing of targets in an unrelated search task if they differed from distractors on a dimension that provided information for online action control. As predicted, however, this effect was observed only if action preparation was signaled by picture cues but not if it was signaled by word cues. We conclude that picture cues are more efficient than word cues in activating the intentional weighting of perceptual dimensions, presumably by specifying not only invariant characteristics of the planned action but also the dimensions of action-specific parameters.

    Full Text Available Franchise is one of successful business strategies in business expansion. Franchise format has been already adopted in all countries. The success is proven in the world and also in Indonesia. Franchise system can be implemented not only in franchisor country but also in other countries. The spirit of internalization is not only because of market saturated, but also to increase reputation of franchise companies and to follow competitors or customers. Important thing discussed in this research is the franchise life-cycle, franchise growth model, and franchise companies’ profile.  It is found that the Indonesia franchise companies are in the introduction stage. The stage in life-cycle shows its reputation. This study used literature review as methodology, and the purpose of this study is to give a big picture for Indonesia franchise companies to make internationalization. There are some Indonesia franchise business profiles in the discussion part. The factors affecting franchise internationalization were analyzed by PESTEL analysis. Some strategies should be prepared in making decision to go international.  At the end, there are some recommendations and future research relating to internationalize franchise business.

    Full Text Available Wordless picture book is an unique book that could help the young learner to get their literacy. The content of the wordless picture book must be communicated through the visual of the illustration. This research discusses a case study of how a kid of six years old produce his narrative through wordless picture book. The kid allowed to see and say on the page and then write the words that he has mentioned. Practicing to read repeatedly which increase fluency will improve his reading comprehension and written expression. This research was conducted to make better understand about the sense - making process that happen when a child works with the wordless picture book. Most sentences or texts were made based on the references and experience from daily life either explicitly or implicitly. In reading wordless book, readers faced the variety of visual signs. These sign systems help reader form a type of framework that show their interpretation of the text and helps them build construction of the story. The researcher wanted to make the reader understand better about the strategies that the child use to make sense of wordless text. The reason of this study is to help how a six year old nonreader would give interpretation to visual cues in wordless picture books. Transacting with the visual text in the books helped the child to make sense of the stories. The data were analyzed based on the principles of qualitative content analysis that involve a systematic review of the data, coding, category construction and analysis. The result of this research is the wordless picture books give opportunity to the children to create the story on their own and to bring in their own understanding of the world to the text.

    Full Text Available Previous research found increased brain responses of men with sexual interest in children (i.e., pedophiles not only to pictures of naked children but also to pictures of child faces. This opens the possibly that pedophilia is linked (in addition to or instead of an aberrant sexual system to an over-active nurturing system. To test this hypothesis we exposed pedophiles and healthy controls to pictures of infant and adult animals during functional magnetic resonance imaging of the brain. By using pictures of infant animals (instead of human infants, we aimed to elicit nurturing processing without triggering sexual processing. We hypothesized that elevated brain responses to nurturing stimuli will be found – in addition to other brain areas – in the anterior insula of pedophiles because this area was repeatedly found to be activated when adults see pictures of babies. Behavioral ratings confirmed that pictures of infant or adult animals were not perceived as sexually arousing neither by the pedophilic participants nor by the heathy controls. Statistical analysis was applied to the whole brain as well as to the anterior insula as region of interest. Only in pedophiles did infants relative to adult animals increase brain activity in the anterior insula, supplementary motor cortex, and dorsolateral prefrontal areas. Within-group analysis revealed an increased brain response to infant animals in the left anterior insular cortex of the pedophilic participants. Currently, pedophilia is considered the consequence of disturbed sexual or executive brain processing, but details are far from known. The present findings raise the question whether there is also an over-responsive nurturing system in pedophilia.

    The dose response curve of paecilomyces violacea was of the type a(simple exponential relationship) and the D 1 0 value was estimated as 0.5 kGy. Qualitative and quantitative variations in the amino acid pool of irradiated p.violacea revealed that seven extracellular amino acids were detected in the control medium namely, cystine, glycine, arginine, proline, valine leucine and cysteine, while, seventeen amino acids were detected in the mycelium of P. violacea (free and combined) under control condition. Nine amino acids in the free state could be detected at different irradiation doses but were completely missed from the amino pool under control condition. But, in the combined state (protein) only five amino acids were detected. The appearance of some amino acids only after irradiation, or their accumulation in amounts higher than control value was explained in the light of their probable role as radioprotectors

    Olive (Olea europaea L.) inflorescences, formed in lateral buds, flower in spring. However, there is some debate regarding time of flower induction and inflorescence initiation. Olive juvenility and seasonality of flowering were altered by overexpressing genes encoding flowering locus T (FT). OeFT1 and OeFT2 caused early flowering under short days when expressed in Arabidopsis. Expression of OeFT1/2 in olive leaves and OeFT2 in buds increased in winter, while initiation of inflorescences occurred i n late winter. Trees exposed to an artificial warm winter expressed low levels of OeFT1/2 in leaves and did not flower. Olive flower induction thus seems to be mediated by an increase in FT levels in response to cold winters. Olive flowering is dependent on additional internal factors. It was severely reduced in trees that carried a heavy fruit load the previous season (harvested in November) and in trees without fruit to which cold temperatures were artificially applied in summer. Expression analysis suggested that these internal factors work either by reducing the increase in OeFT1/2 expression or through putative flowering repressors such as TFL1. With expected warmer winters, future consumption of olive oil, as part of a healthy Mediterranean diet, should benefit from better understanding these factors. © 2017 John Wiley & Sons Ltd.

    According to the perceptual symbols theory (Barsalou, 1999), sensorimotor simulations underlie the representation of concepts. We investigated whether recognition memory for pictures of concepts was facilitated by earlier representation of visual properties of those concepts. During study, concept names (e.g., apple) were presented in a property verification task with a visual property (e.g., shiny) or with a nonvisual property (e.g., tart). Delayed picture recognition memory was better if the concept name had been presented with a visual property than if it had been presented with a nonvisual property. These results indicate that modality-specific simulations are used for concept representation.

The priming effects of secure base pictures and positive pictures on evaluation of neutral stimuli were examined. The attachment dimensions, both anxiety and avoidance, were also measured for all participants. The subliminal priming of secure base pictures was found to lead to greater positive liking ratings to neutral stimuli than neutral priming pictures or no pictures in the Chinese but not in the Japanese sample. The results were discussed in the context of the dual-process theory of the secure base schema.

    Full Text Available This study examines the relationship between Internet use and social capital in an intercultural context and investigates how different Internet use functions are related to social capital. Data were collected from the survey among 155 Chinese international students studying in Japan’s universities. The results showed that Internet use intensity negatively influenced individuals’ bonding social capital. It was also found that the use of the Internet for staying informed would have positive effects on bridging social capital. However, no significant relationship was found between using the Internet for interacting with others and the two types of social capital. These findings fill the gaps in existing studies on Internet effectiveness and help to provide knowledge about the influences of various Internet use functions on establishing and maintaining social ties.

    2015-12-01

    Full Text Available In Jože Hradil’s Faceless Pictures [Slike brez obrazov] the characters go astray or get into the attraction of adventures and set off for a journey. The spiritual and identity shifts can be interpreted along these eternal human desires as well. A patchwork of remembering and forgetting, the internal journeys of identity preservation, spontaneous or forced assimilation, tolerance and all kinds of politics-induced human deformations are depicted in the novel. The text traces the roles of the journey defined by Jean Chevalier and Alain Gheerbrant such as the search for justice, peace, immortality and finding the spiritual center. This study examines how the concrete physical journey changes into an internal road determining the evolution of personality.

    Full Text Available "The Picture of Nobody" posits that Shakespeare's birth as an author in print was “aborted” by strategies of absence that avoided institutionalized forms of authorial representation. Wilson argues that these possibly deliberate acts of evasion and self-concealment are linked to early modern problems of social class and to Shakespeare's ambition to become "a subject without an identity".

    Polyakov, D.

    1995-01-01

    We explore the geometrical properties of fermionic vertex operators for a NSR superstring in order to establish the connection between world-sheet and target space supersymmetries. The mechanism of picture changing is obtained as a result of imposing certain constraints on a world-sheet gauge group of the NSR superstring theory. We find that picture-changing operators of different integer ghost numbers form a polynomial ring. By using properties of the picture-changing formalism, we establish a relation between the NSR and GS string theories. We show that, up to picture-changing transformations, the stress-energy tensor of the N=1 NSR superstring theory can be obtained from the stress-energy tensor of the N=1 GS superstring theory in a flat background by a simple field redefinition. The equations of motion of a GS superstring are shown to be fulfilled in the NSR operator formalism; they are also shown to be invariant under κ-symmetry, in terms of operator products in the NSR theory. This allows us to derive the space-time supersymmetry transformation laws for the NSR string theory. Then, we explore the properties of the κ-symmetry in the NSR formalism and find that it leads to some new relations between bosonic and fermionic correlation functions. (orig.)

    2018-04-01

    We describe the Multilanguage Written Picture Naming Dataset. This gives trial-level data and time and agreement norms for written naming of the 260 pictures of everyday objects that compose the colorized Snodgrass and Vanderwart picture set (Rossion & Pourtois in Perception, 33, 217-236, 2004). Adult participants gave keyboarded responses in their first language under controlled experimental conditions (N = 1,274, with subsamples responding in Bulgarian, Dutch, English, Finnish, French, German, Greek, Icelandic, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish). We measured the time to initiate a response (RT) and interkeypress intervals, and calculated measures of name and spelling agreement. There was a tendency across all languages for quicker RTs to pictures with higher familiarity, image agreement, and name frequency, and with higher name agreement. Effects of spelling agreement and effects on output rates after writing onset were present in some, but not all, languages. Written naming therefore shows name retrieval effects that are similar to those found in speech, but our findings suggest the need for cross-language comparisons as we seek to understand the orthographic retrieval and/or assembly processes that are specific to written output.

    Cycowicz, Y M; Friedman, D; Snodgrass, J G; Duff, M

    2001-01-01

    The present experiment investigated the developmental aspects of source compared to item memory. College students and 7-8-year-old children viewed pictures drawn in red or green during a study phase, and were asked either to remember the pictures for a subsequent recognition test, or to remember both the pictures and their associated colors for a subsequent source memory test. In the test phase, new and old pictures were presented in black. In the recognition task, participants were asked to make binary old/new recognition judgments, while in the source task, they were asked to make trinary old-green/old-red/new source judgements. Performance on all tasks improved with increasing age, but the age difference for source was much larger than that for item memory. It has been suggested that the frontal lobes play a critical role in the retrieval of source information, and that this brain region relative to the medial temporal lobes continues to develop into late adolescence. Thus, it is possible that immaturity of the frontal lobes may be causally related to the children's lower performance on the source memory task.

  6. Illegal performance enhancing drugs and doping in sport: a picture-based brief implicit association test for measuring athletes’ attitudes

    Science.gov (United States)

    2014-01-01

    Background Doping attitude is a key variable in predicting athletes’ intention to use forbidden performance enhancing drugs. Indirect reaction-time based attitude tests, such as the implicit association test, conceal the ultimate goal of measurement from the participant better than questionnaires. Indirect tests are especially useful when socially sensitive constructs such as attitudes towards doping need to be described. The present study serves the development and validation of a novel picture-based brief implicit association test (BIAT) for testing athletes’ attitudes towards doping in sport. It shall provide the basis for a transnationally compatible research instrument able to harmonize anti-doping research efforts. Method Following a known-group differences validation strategy, the doping attitudes of 43 athletes from bodybuilding (representative for a highly doping prone sport) and handball (as a contrast group) were compared using the picture-based doping-BIAT. The Performance Enhancement Attitude Scale (PEAS) was employed as a corresponding direct measure in order to additionally validate the results. Results As expected, in the group of bodybuilders, indirectly measured doping attitudes as tested with the picture-based doping-BIAT were significantly less negative (η2 = .11). The doping-BIAT and PEAS scores correlated significantly at r = .50 for bodybuilders, and not significantly at r = .36 for handball players. There was a low error rate (7%) and a satisfactory internal consistency (r tt  = .66) for the picture-based doping-BIAT. Conclusions The picture-based doping-BIAT constitutes a psychometrically tested method, ready to be adopted by the international research community. The test can be administered via the internet. All test material is available “open source”. The test might be implemented, for example, as a new effect-measure in the evaluation of prevention programs. PMID:24479865

    Kurdi, Benedek; Lozano, Shayn; Banaji, Mahzarin R

    2017-04-01

    We introduce the Open Affective Standardized Image Set (OASIS), an open-access online stimulus set containing 900 color images depicting a broad spectrum of themes, including humans, animals, objects, and scenes, along with normative ratings on two affective dimensions-valence (i.e., the degree of positive or negative affective response that the image evokes) and arousal (i.e., the intensity of the affective response that the image evokes). The OASIS images were collected from online sources, and valence and arousal ratings were obtained in an online study (total N = 822). The valence and arousal ratings covered much of the circumplex space and were highly reliable and consistent across gender groups. OASIS has four advantages: (a) the stimulus set contains a large number of images in four categories; (b) the data were collected in 2015, and thus OASIS features more current images and reflects more current ratings of valence and arousal than do existing stimulus sets; (c) the OASIS database affords users the ability to interactively explore images by category and ratings; and, most critically, (d) OASIS allows for free use of the images in online and offline research studies, as they are not subject to the copyright restrictions that apply to the International Affective Picture System. The OASIS images, along with normative valence and arousal ratings, are available for download from www.benedekkurdi.com/#oasis or https://db.tt/yYTZYCga .

  8. Analytic solution of heat and mass transfer over a permeable stretching plate affected by chemical reaction, internal heating, Dufour-Soret effect and hall effect

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available The analytical solution is derived for the steady MHD mixed convection, laminar, heat and mass transfer over an isothermal, inclined permeable stretching sheet, immersed in a uniform porous medium in the presence of chemical reaction, thermal radiation, Dufour and Soret effects, an external transverse magnetic field, and internal heating. The governing equations are transformed into a dimensionless coupled system of non-linear ordinary differential equations and then solved analytically by the homotopy analysis method. A parametric study illustrating the influence of the chemical reaction, magnetic field, porous medium inertia parameter, and the Dufour and Soret numbers on the fluid velocity, temperature, and concentration are investigated through the obtained analytic solution. As well as the local Nusselt and the Sherwood numbers is conducted. The obtained results are presented graphically and the physical aspects of the problem are discussed. The obtained solution has been tested numerically for some values of the system parameters. Comparison with previously reported numerical results is tabulated and agreement is recorded. Analytic form of some characteristic parameters, e. g. the local skin-friction coefficient, the local Nusselt number, and the local Sherwood number, stress at the stretching surface, local mass transfer coefficient, the local wall mass flux, the local heat transfer coefficient and the local heat flux, are given due to the obtained analytic solution.

    To assess internal radiocontamination of patients with end-stage renal disease (ESRD) who were regularly taking haemodialysis (HD) and living in areas affected by the crippled Fukushima Daiichi nuclear plant after the Great East Japan earthquake on 11 March 2011. Internal radiocontamination in 111 patients with ESRD regularly taking HD at Jyoban Hospital in Iwaki city, Fukushima from July 2012 to November 2012 was assessed with a whole body counter (WBC). The maximum annual effective dose was calculated from the detected Cs-137 levels. Interviews concerning patient dietary preferences and outdoor activities were also conducted. Among the 111 patients tested, internal radiocontamination with Cs-137 was detected in two participants, but the levels were marginal and just exceeded the detection limit (250 Bq/body). The tentatively calculated maximum annual effective dose ranged from 0.008 to 0.009 mSv/year, which is far below the 1 mSv/year limit set by the government of Japan. Relative to 238 non-ESRD participants, patients with ERSD had significantly more opportunities to consume locally grown produce that was not distributed to the market (pnuclear plant. Although HD is suggested to promote Cs-137 excretion, continuous inspection of locally grown produce together with WBC screening for radiocontamination should be continued for patients with ESRD regularly taking HD.

  12. Proton structure functions in the dipole picture of BFKL dynamics

    International Nuclear Information System (INIS)

    Navelet, H.; Wallon, S.

    1996-06-01

    The F 2 , F G , R=F L /F T proton structure functions are derived in the QCD dipole picture. Assuming k T and renormalization-group factorization, we relate deep-inelastic proton scattering to deep-inelastic onium scattering. We get a three-parameter fit of the 1994 H1 data in the low-x, moderate Q 2 range. The ratios F G /F 2 and R are predicted without further adjustment. The dipole picture of BFKL dynamics is shown to provide a relevant model for quantitatively describing the proton structure functions at HERA. The predictions for F 2 and F G are compatible with next-to-leading DGLAP analysis, while R is expected to be significantly lower at very small x. (orig.)

  13. Cognitive impairments of aphasics in picture sorting and matching tasks.

    Science.gov (United States)

    Cohen, R; Glöckner-Rist, A; Lutz, M; Maier, T; Meier, E

    1982-01-01

    On the basis of earlier experiments showing a differential deficit of aphasics in picture sorting and matching tasks, two experiments were conducted to test the conjecture of a specific deficit of aphasics in the analytical appraisal of individual features. Broca's and Wernicke's aphasics--according to clinical diagnoses and the Aachener Aphasie Test--were compared with patients having right-hemisphere lesions or left-hemisphere lesions without aphasia. Both groups of aphasics differed from the control groups in the sorting task, irrespective of the sorting criterion, but the differences were small. The picture matching task did not discriminate between groups. Obviously, the basic assumption has to be modified with respect to specific conditions of task requirements. The experimental literature is reviewed.

  14. The sources of Gessner's pictures for the Historia animalium.

    Science.gov (United States)

    Kusukawa, S

    2010-07-01

    Gessner's sources for the pictures in his Historia animalium were varied in kind and in quality. This should be understood within the larger context of the Historia animalium in which Gessner sought to collect everything ever written about animals, an enterprise that could not be completed by a single individual. Just as Gessner did not distil or reduce similar texts but retained these as well as contradictory or false textual descriptions as part of a repository of knowledge, so also Gessner included several pictures of the same animal, false or badly drawn ones, and juxtaposed erroneous and 'true' images. The attribution of images to witnesses and correspondences also reflects Gessner's strategy to credit those who drew his attention to new information first. The sources of Gessner's images thus indicate how his visual world encompassed more than the strictly self-observable, and a pictorial practice that was intimately connected with textual traditions and intellectual networks.

    2009-01-01

    This paper discusses change management in networks. The literature on business networks tends to downplay the role of managerial initiative in network change. The change management literature addresses such initiative, but with its single-firm perspective it overlooks the interdependence of network...... actors. In exploring the void between these two streams of literature, we deploy the concept of network pictures to discuss managed change in network settings. We analyze a change project from the furniture industry and address the consequences of attempting to manage change activities in a network...... context characterized by limited managerial authority over these activities. Our analysis suggests that change efforts unfold as a negotiated process during which the change project is re-negotiated to fit the multiple actor constituencies.

    The present article introduces a Russian-language database of 375 action pictures and associated verbs with normative data. The pictures were normed for name agreement, conceptual familiarity, and subjective visual complexity, and measures of age of acquisition, imageability, and image agreement were collected for the verbs. Values of objective visual complexity, as well as information about verb frequency, length, argument structure, instrumentality, and name relation, are also provided. Correlations between these parameters are presented, along with a comparative analysis of the Russian name agreement norms and those collected in other languages. The full set of pictorial stimuli and the obtained norms may be freely downloaded from http://neuroling.ru/en/db.htm for use in research and for clinical purposes.

  1. TopicPanorama: A Full Picture of Relevant Topics.

    Science.gov (United States)

    Wang, Xiting; Liu, Shixia; Liu, Junlin; Chen, Jianfei; Zhu, Jun; Guo, Baining

    2016-12-01

    This paper presents a visual analytics approach to analyzing a full picture of relevant topics discussed in multiple sources, such as news, blogs, or micro-blogs. The full picture consists of a number of common topics covered by multiple sources, as well as distinctive topics from each source. Our approach models each textual corpus as a topic graph. These graphs are then matched using a consistent graph matching method. Next, we develop a level-of-detail (LOD) visualization that balances both readability and stability. Accordingly, the resulting visualization enhances the ability of users to understand and analyze the matched graph from multiple perspectives. By incorporating metric learning and feature selection into the graph matching algorithm, we allow users to interactively modify the graph matching result based on their information needs. We have applied our approach to various types of data, including news articles, tweets, and blog data. Quantitative evaluation and real-world case studies demonstrate the promise of our approach, especially in support of examining a topic-graph-based full picture at different levels of detail.

    Full Text Available Does the way in which a scene is viewed influence the interpretation of the role of the characters that appear in it, and does narrative context influence sensitivity to camera angle? In the linear conditions of the present study, each of 3 stories consisted of a sequence of 5 pictures. Pictures 2 and 3 introduced the 2 characters with either a high-angle, an eye-level, or a low-angle shot. In the random conditions, the 5 pictures were rearranged into a random order. Immediately after viewing each story, the 2 characters were rated on the 3 factors of Osgood's semantic differential (Evaluation, Potency, & Activation. Thereafter, an acceptable end to each of the 3 stories was to be chosen on a multiple-choice questionnaire. The results show a significant effect of the camera angle on the factor "Potency" under the linear condition: A low-angle shot elicited more potency. In addition, for one of the 3 stories in which the 2 characters were engaged in a common activity (chess playing, there was a significant difference on the choice of the probable ends as a function of camera position: The character, presented with a low-angle shot, was perceived as the winning player.

  3. Interacting-string picture of the fermionic string

    This report gives a review of the interacting-string picture of the Bose string. In the present lecture, the author outlines a similar treatment of the Fermionic string. The quantization of the free Fermionic string is carried out to the degrees of freedom x, representing the displacement of the string. Also presented are Grassman degrees of freedom S distributed along the string. The report pictures the fermionic string as a string of dipoles. The general picture of the interaction of such strings by joining and splitting is the same as for the Bose string. The author does not at present have the simplest formula for fermion string scattering amplitudes. A less detailed treatment is given than for the Bose string. The report sets up the functional-integration formalism, derives the analog mode, and indicates in general, terms how the conformal transformation to the z-plane may be performed. The paper concludes by stating without proof the formula for the N-article tree amplitude in the manifestly supersymmetric formalism

    Full Text Available Feminism as it is viewed in the modern world is appreciated in various products. It has become a common sense and understanding that women keep on having movements to pursue equality to men. Literary works play an important role to promote the awareness and spirit of women emancipation. It becomes an interesting view to examine how this women movement is introduced to women in general regardless age. This issue has also been introduced to kids through various ways; among them are novel sand movies. A movie produced by Walt Disney Animation Studios, Frozen, is rich in the elements of the story, animations, pictures, and music. The story itself draws the young readers of the stories of princesses with abundant moral issued of goodness against badness, loyalty, and courage. However, examining deeper to the lyrics of the soundtracks, readers can get a more vivid picture of modern feminism through encouragements of women‘s struggles to face problems, to have bargaining power, and to have right to decide what the best for them. This paper is aimed to find out a picture of modern feminism through the lyrics of the soundtracks. The result of the study can be used to track the development of feminism ideas in modern world.

  5. Stress priming in picture naming: an SOA study.

    Schiller, Niels O; Fikkert, Paula; Levelt, Clara C

    2004-01-01

    This study investigates whether or not the representation of lexical stress information can be primed during speech production. In four experiments, we attempted to prime the stress position of bisyllabic target nouns (picture names) having initial and final stress with auditory prime words having either the same or different stress as the target (e.g., WORtel-MOtor vs. koSTUUM-MOtor; capital letters indicate stressed syllables in prime-target pairs). Furthermore, half of the prime words were semantically related, the other half unrelated. Overall, picture names were not produced faster when the prime word had the same stress as the target than when the prime had different stress, i.e., there was no stress-priming effect in any experiment. This result would not be expected if stress were stored in the lexicon. However, targets with initial stress were responded to faster than final-stress targets. The reason for this effect was neither the quality of the pictures nor frequency of occurrence or voice-key characteristics. We hypothesize here that this stress effect is a genuine encoding effect, i.e., words with stress on the second syllable take longer to be encoded because their stress pattern is irregular with respect to the lexical distribution of bisyllabic stress patterns, even though it can be regular with respect to metrical stress rules in Dutch. The results of the experiments are discussed in the framework of models of phonological encoding.

    The automatic scanning and measuring system ''Coccinelle'' built in the Laboratoire de Physique Corpusculaire of College de France, is specially made for the pictures of the new large bubble chambers like BEBC and Mirabelle. This device uses the spot of a high precision cathode ray tube for the analysis of the picture according to a scanning window. The signal of a photomultiplier located behind the picture gives, after processing, the useful information in the form of coordinates of the analyzed points. Electronics, connected to a computer, generates the movements of the spot, the backward and forward movement of the films, and gives the right information for the programs of geometrical reconstruction of the tracks. The use of the device is based upon the collaboration of a programmed automaton and a human operator that have conversational facilities: TV display, light-pen and function keyboard. Beyond a detailed description of the whole device, this thesis insists especially on the following electronic parts: sweep generation of the spot, photomultiplier signal processing [fr

    Original pictures installed in the 1st and 2nd generation type central control panels (CCP) and new 'Awarable and Complex' pictures were made on personal computers and evaluated. A total 18 of actual plant operators (M=32.3, SD=10.5 years old) participated in the evaluation. The operators rated the new CRT pictures highly. The response times using the new CRT pictures were shorter than those by the original pictures. Both results suggested that the CRT picture design guidelines based on the operators' plant images were effective for improving their performance. (author)

  9. Cortical activity during cued picture naming predicts individual differences in stuttering frequency.

    2016-09-01

    Developmental stuttering is characterized by fluent speech punctuated by stuttering events, the frequency of which varies among individuals and contexts. Most stuttering events occur at the beginning of an utterance, suggesting neural dynamics associated with stuttering may be evident during speech preparation. This study used EEG to measure cortical activity during speech preparation in men who stutter, and compared the EEG measures to individual differences in stuttering rate as well as to a fluent control group. Each trial contained a cue followed by an acoustic probe at one of two onset times (early or late), and then a picture. There were two conditions: a speech condition where cues induced speech preparation of the picture's name and a control condition that minimized speech preparation. Across conditions stuttering frequency correlated to cue-related EEG beta power and auditory ERP slow waves from early onset acoustic probes. The findings reveal two new cortical markers of stuttering frequency that were present in both conditions, manifest at different times, are elicited by different stimuli (visual cue, auditory probe), and have different EEG responses (beta power, ERP slow wave). The cue-target paradigm evoked brain responses that correlated to pre-experimental stuttering rate. Copyright © 2016 International Federation of Clinical Neurophysiology.

    2016-03-01

    Evaluative conditioning is a form of affective learning in which initially neutral stimuli acquire an affective value through association with negative or positive stimuli. Recent research shows an important role for cognitive resources in this type of learning. This form of affective learning has rarely been studied in intellectual disability (ID). We examined evaluative conditioning in 16 adults with mild to moderate ID compared to age- and gender-matched control participants. Neutral shapes and symbols were repeatedly paired with positive, neutral or negative unconditioned stimuli (faces or International Affective Picture System images). There was also an extinction phase. There was significant acquisition of conditioning in both groups. Stimuli paired with positive images were evaluated more positively, and stimuli paired with negative images were evaluated more negatively. Post-extinction ratings however show that these novel affective associations were not maintained by individuals with ID as much as by individuals in the control group. We conclude that ID modulates some aspects of affective learning but not necessarily initial preference acquisition. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Emotional content typically facilitates subsequent memory, known as the emotional enhancement effect. We investigated whether emotional content facilitates spatial and item memory in patients with Alzheimer's dementia (AD). Twenty-three AD patients, twenty-three healthy elderly, and twenty-three young adults performed a picture relocation task and a delayed recognition task with positive, negative, and neutral stimuli. AD patients showed a benefit in immediate spatial memory for positive pictures, while healthy young and older participants did not benefit from emotional content. No emotional enhancement effects on delayed item recognition were seen. We conclude that AD patients may have a memory bias for positive information in spatial memory. Discrepancies between our findings and earlier studies are discussed.

    According to the snake detection hypothesis (Isbell, 2006), fear specifically of snakes may have pushed evolutionary changes in the primate visual system allowing pre-attentional visual detection of fearful stimuli. A previous study demonstrated that snake pictures, when compared to spiders or bird pictures, draw more early attention as reflected by larger early posterior negativity (EPN). Here we report two studies that further tested the snake detection hypothesis. In Study 1, we tested whether the enlarged EPN is specific for snakes or also generalizes to other reptiles. Twenty-four healthy, non-phobic women watched the random rapid serial presentation of snake, crocodile, and turtle pictures. The EPN was scored as the mean activity at occipital electrodes (PO3, O1, Oz, PO4, O2) in the 225-300 ms time window after picture onset. The EPN was significantly larger for snake pictures than for pictures of the other reptiles. In Study 2, we tested whether disgust plays a role in the modulation of the EPN and whether preferential processing of snakes also can be found in men. 12 men and 12 women watched snake, spider, and slug pictures. Both men and women exhibited the largest EPN amplitudes to snake pictures, intermediate amplitudes to spider pictures and the smallest amplitudes to slug pictures. Disgust ratings were not associated with EPN amplitudes. The results replicate previous findings and suggest that ancestral priorities modulate the early capture of visual attention.

    Objective Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor would be diminished ability to engage the mechanism of emotional habituation. We tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy controls, and a psychopathological control group of avoidant personality disorder patients. Method During fMRI scan acquisition, borderline patients, healthy controls and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeat versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. Results Unlike healthy controls, neither borderline nor avoidant personality disorder participants showed increased activity in dorsal anterior cingulate cortex when viewing repeat versus novel pictures. This failure to increase dorsal anterior cingulate activity was associated with greater affective instability in borderline participants. In addition, borderline and avoidant participants showed smaller insula-amygdala connectivity increases than healthy participants and did not show habituation in ratings of the emotional intensity of the images as did healthy participants. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate connectivity during habituation. Conclusions Borderline patients fail to habituate to negative pictures as do healthy participants and differ from both healthy controls and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline patients

    Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor is diminished ability to engage the mechanism of emotional habituation. The authors tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy comparison subjects, and a psychopathological comparison group of patients with avoidant personality disorder. During fMRI scanning, borderline patients, healthy subjects, and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeated versus novel negative picture viewing were compared between groups.

    This paper introduces a picture system that can be used in functional imaging experiments exploring interpersonal relations. This is important for psychotherapy research to understand the neural basis of psychological treatment effects. Pictures have many advantages for the design of functional imaging experiments, but no picture system illustrating interpersonal behavior patterns is, to date, available. We therefore developed, on the basis of a validated card-sorting test, the Interpersonal Relations Picture System. In summary, 43 pictures with 2 or more stick figures in different social situations and 9 control pictures were composed. To test the relation between each picture and the appropriate description, two successive online surveys, including 1058 and 675 individuals respectively, were conducted. Using two question types, the grade expressiveness of each picture was assessed. In total, 24 pictures and 6 control pictures met our criteria for sufficient strength and consistency with the appropriate description. Both measures are correlated with each other in all pictures illustrating interpersonal behavior, but not in the control pictures. Relations to other stimulus types and the applicability of the new picture system in functional neuroimaging methods are discussed. It is concluded that the new system will be helpful in studying the profound effect of relational change in psychotherapy.

    Individuals with schizophrenia are more prone to violent behaviors than the general population. It is increasingly recognized that processing of emotionally valenced stimuli is impaired in schizophrenia, a deficit that may play a role in aggressive behavior. Our goal was to establish whether patients with a history of violence would show more severe deficits in processing emotionally valenced inputs than non-violent patients. Using event-related potentials, we measured how early during processing of emotional valence, evidence of aberrant function was observed. A total of 42 schizophrenia patients (21 with history of violence; 21 without) and 28 healthy controls were tested. Participants performed an inhibitory control task, making speeded responses to pictorial stimuli. Pictures occasionally repeated twice and participants withheld responses to these repeats. Valenced pictures from the International Affective Picture System were presented. Results in controls showed modulations during the earliest phases of sensory processing (<100 ms) for negatively valenced pictures. A cascade of modulations ensued, involving sensory and perceptual processing stages. In contrast, neither schizophrenia group showed early differentiation. Non-violent patients showed earliest modulations beginning ∼150 ms. For violent patients, however, earliest modulations were further delayed and highly attenuated. The current study reveals sensory-perceptual processing dysfunction for negatively valenced inputs, which is particularly pronounced in aggressive patients.

    We estimate the role of biofuel policies in determining which country is the price leader in world biofuel markets using a cointegration analysis and a Vector Error Correction (VEC) model. Weekly prices are analyzed for the EU, US, and Brazilian ethanol and biodiesel markets in the 2002–2010 and 2005–2010 time periods, respectively. The US blender's tax credit and Brazil's consumer tax exemption are found to play a role in determining the ethanol prices in other countries. For biodiesel, our results demonstrate that EU policies – the consumer tax exemption and blending target – tend to determine the world biodiesel price. - Highlights: • We estimate the role of biofuel policies in determining biofuel prices. • We use a cointegration analysis and the Vector Error Correction (VEC) model. • The biofuel policies in US and Brazil determine the world ethanol prices. • EU biofuel policies tend to form the world biodiesel price

    Health policy makers have examined the impact of economic policies and a nation's social development on the health of its population. The purpose of this research was to investigate the association between health care expenditures, socioeconomic factors, and caries levels in 109 countries representing an array of social and economic conditions, and to determine how such factors are related to caries experience at different levels of economic development. Countries were divided into established market economies and three groups of developing nations, based on their GNP (high, medium, low income). Total health expenditures as percent GDP and as US dollars per capita, public expenditures and aid flow as percent of total health expenditures, dentists per 100,000 population, per capita sugar consumption, and urbanization of the population were compared among these countries. Correlations between these variables, and decayed, missing and filled teeth (DMFT) of 12-year-olds in these countries were assessed. The highest correlations were found between DMFT and public expenditures, sugar consumption, and urbanization. Highly significant differences emerged across nation groups by stages of development on several variables. The findings suggest that it is important to consider the stage of development of a given country when planning caries prevention policies and programs. Such a contextual approach is more likely to be successful in reducing caries levels.

    2014-01-01

    The Two-Process theory of psychopathy posits distinct etiological mechanisms contribute to the disorder: 1) a weakness in defensive (fear) reactivity related to affective-interpersonal features, and 2) impaired cognitive-executive functioning, marked by reductions in brain responses such as P3, related to impulsive-antisocial features. The current study examined relations between psychopathy factors and electrocortical response to emotional and neutral pictures in male offenders (N=139) assessed using the Psychopathy Checklist-Revised (PCL-R). Impulsive-antisocial features of the PCL-R (Factor 2) were associated with reduced amplitude of earlier P3 brain response to pictures regardless of valence, whereas the affective-interpersonal dimension (Factor 1) was associated specifically with reductions in late positive potential response to aversive pictures. Findings provide further support for the Two-Process theory and add to a growing body of evidence linking the impulsive-antisocial facet of psychopathy to the broader construct of externalizing proneness. Findings are discussed in terms of current initiatives directed at incorporating neuroscientific concepts into psychopathology classification. PMID:25603361

    A simple automatic digitizer for graphs and polaroid pictures for use with minicomputers has been developed. This system comprises a slightly modified commercial TV camera, a digitizer that processes the TV video signals and delivers in a digital form a sequence of the ordinates of the analyzed graph, and an optional TV monitor and CRT oscilloscope interfaced to the mini-computer. Special software which acquires the digitized data and corrects for improper alignments and aberrations caused by the TV camera was written. This software permits the composition of the system from common elements present in most laboratories. (Auth.)

    A quantum particle with potential energy V(q-hat, t) is considered in the frame of a phase-space picture of the quantum theory, and the interconnection between quantum mechanics and a h-bar dependent extended classical dynamics is analysed. The initial position-space wavefunction determines the initial conditions for a set of Hamilton-like equations that leads up to an ensemble of complex-valued phase-space trajectories. The one-dimensional driven harmonic oscillator is used for illustrating the method, and for generating a complete set of phase-space functions.

    We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of "seeing the big picture" and the broaden-and-build model. Experiment 1 (n = 164) is a laboratory-based experiment, in which we manipulated the attentional scope by showing participants zoomed-out or zoomed-in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Viewers can easily spot a target picture in a rapid serial visual presentation (RSVP), but can they do so if more than 1 picture is presented simultaneously? Up to 4 pictures were presented on each RSVP frame, for 240 to 720 ms/frame. In a detection task, the target was verbally specified before each trial (e.g., "man with violin"); in a…

  18. Case Study: A Picture Worth a Thousand Words? Making a Case for Video Case Studies

    2014-01-01

    A picture, they say, is worth a thousand words. If a mere picture is worth a thousand words, how much more are "moving pictures" or videos worth? The author poses this not merely as a rhetorical question, but because she wishes to make a case for using videos in the traditional case study method. She recommends four main approaches of…

    Two experiments investigated the processes underlying the picture superiority effect on recognition memory. Studied pictures were associated with higher accuracy than studied words, regardless of whether test stimuli were words (Experiment 1) or pictures (Experiment 2). Event-related brain potentials (ERPs) recorded during test suggested that the…
