    Introduction Given the proven effects of weather on the human organism, an attempt to examine its effects on a psychic and emotional level has been made. Emotions affect the bio-tonus, working ability and concentration, hence their significance in various domains of economic life, such as health care, education, transportation, tourism, etc. Data and methods The research has been made in Sofia City within a period of 8 months, using 5 psychological methods (Eysenck Personality Questionnaire (EPQ), State-Trait Anxiety Inventory (STAI), Test for Self-assessment of the emotional state (developed by Wessman and Ricks), Test for evaluation of moods and Test "Self-confidence - Activity - Mood" (developed by the specialists from the Military Academy in Saint Petersburg). The Fiodorov-Chubukov's complex-climatic method was used to characterize meteorological conditions because of the purpose to include in the analysis a maximal number of meteorological elements. 16 weather types are defined in dependence of the meteorological elements values according to this method. Abrupt weather changes from one day to another, defined by the same method, were considered as well. Results and discussions The results obtained by t-test show that the different categories of weather lead to changes in the emotional status, which indicates a character either positive or negative for the organism. The abrupt weather changes, according to expectations, have negative effect on human emotions but only when a transition to the cloudy weather or weather type, classified as "unfavourable" has been realized. The relationship between weather and human emotions is rather complicated since it depends on individual characteristics of people. One of these individual psychological characteristics, marked by the dimension "neuroticism", has a strong effect on emotional reactions in different weather conditions. Emotionally stable individuals are more "protected" to the weather influence on their emotions

    According to the basic emotional theory, the artificial emotional model based on the finite state machine(FSM) was presented. In finite state machine model of emotion, the emotional space included the basic emotional space and the multiple emotional spaces. The emotion-switching diagram was defined and transition function was developed using Markov chain and linear interpolation algorithm. The simulation model was built using Stateflow toolbox and Simulink toolbox based on the Matlab platform.And the model included three subsystems: the input one, the emotion one and the behavior one. In the emotional subsystem, the responses of different personalities to the external stimuli were described by defining personal space. This model takes states from an emotional space and updates its state depending on its current state and a state of its input (also a state-emotion). The simulation model realizes the process of switching the emotion from the neutral state to other basic emotions. The simulation result is proved to correspond to emotion-switching law of human beings.

Sixty seven undergraduates participated in the procedure, which lasted 75 min and was divided into three stages. At Time 1, subjects answered the State-Trait Anxiety Inventory (STAI)-S, Profile of Mood States (POMS)-A, and EI was assessed by Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). At Time 2, negative emotions were induced by nine pictures taken from the International Affective Picture System and participants were asked to complete a second STAI-S and POMS-B questionnaires. At Time 3 participants were allowed to rest doing a distracting task and participants were asked to complete a third STAI-S and POMS-A questionnaires. Results showed that the branches of the MSCEIT emotional facilitation and emotional understanding are related to previous mood states and mood recovery, but not to mood reactivity. This finding contrasts nicely with studies on which emotional recovery was assessed in relation to EI self-reported measures, highlighting the perception and emotional regulation.

Student’s emotions like self-esteem, motivation, commitment, and others that are believed to be determinant in student’s performance can not be ignored, as they are known (affective states and also learning styles to greatly influence student’s learning. The ability of the computer to evaluate the emotional state of the user is getting bigger attention. By evaluating the emotional state, there is an attempt to overcome the barrier between man and non-emotional machine. Recognition of a real time emotion in e-learning by using webcams is research area in the last decade. Improving learning through webcams and microphones offers relevant feedback based upon learner’s facial expressions and verbalizations. The majority of current software does not work in real time – scans face and progressively evaluates its features. The designed software works by the use neural networks in real time which enable to apply the software into various fields of our lives and thus actively influence its quality. Validation of face emotion recognition software was annotated by using various experts. These expert findings were contrasted with the software results. An overall accuracy of our software based on the requested emotions and the recognized emotions is 78%. Online evaluation of emotions is an appropriate technology for enhancing the quality and efficacy of e-learning by including the learner´s emotional states.

    Processing emotional body expressions has become recently an important topic in affective and social neuroscience along with the investigation of facial expressions. The objective of the study is to review the literature on emotional body expressions in order to discuss the current state of knowledge on this topic and identify directions for future research. The following electronic databases were searched: PsychINFO, Ebsco, ERIC, ProQuest, Sagepub, and SCOPUS using terms such as "body," "bodily expression," "body perception," "emotions," "posture," "body recognition" and combinations of them. The synthesis revealed several research questions that were addressed in neuroimaging, electrophysiological and behavioral studies. Among them, one important question targeted the neural mechanisms of emotional processing of body expressions to specific subsections regarding the time course for the integration of emotional signals from face and body, as well as the role of context in the perception of emotional signals. Processing bodily expression of emotion is similar to processing facial expressions, and the holistic processing is extended to the whole person. The current state-of-the-art in processing emotional body expressions may lead to a better understanding of the underlying neural mechanisms of social behavior. At the end of the review, suggestions for future research directions are presented.

    Full Text Available Diurnal emotional experiences seem to affect several characteristics of sleep architecture. However, this influence remains unclear, especially for positive emotions. In addition, electrodermal activity (EDA, a sympathetic robust indicator of emotional arousal, differs depending on the sleep stage. The present research has a double aim: to identify the specific effects of pre-sleep emotional states on the architecture of the subsequent sleep period; to relate such states to the sympathetic activation during the same sleep period.Twelve healthy volunteers (20.1 ± 1.0 yo. participated in the experiment and each one slept 9 nights at the laboratory, divided into 3 sessions, one per week. Each session was organized over three nights. A reference night, allowing baseline pre-sleep and sleep recordings, preceded an experimental night before which participants watched a negative, neutral, or positive movie. The third and last night was devoted to analyzing the potential recovery or persistence of emotional effects induced before the experimental night. Standard polysomnography and EDA were recorded during all the nights.Firstly, we found that experimental pre-sleep emotional induction increased the Rapid Eye Movement (REM sleep rate following both negative and positive movies. While this increase was spread over the whole night for positive induction, it was limited to the second half of the sleep period for negative induction. Secondly, the valence of the pre-sleep movie also impacted the sympathetic activation during Non-REM stage 3 sleep, which increased after negative induction and decreased after positive induction.Pre-sleep controlled emotional states impacted the subsequent REM sleep rate and modulated the sympathetic activity during the sleep period. The outcomes of this study offer interesting perspectives related to the effect of diurnal emotional influences on sleep regulation and open new avenues for potential practices designed to

  11. Immediacy bias in emotion perception: current emotions seem more intense than previous emotions.

    People tend to perceive immediate emotions as more intense than previous emotions. This immediacy bias in emotion perception occurred for exposure to emotional but not neutral stimuli (Study 1), when emotional stimuli were separated by both shorter (2 s; Studies 1 and 2) and longer (20 min; Studies 3, 4, and 5) delays, and for emotional reactions to pictures (Studies 1 and 2), films (Studies 3 and 4), and descriptions of terrorist threats (Study 5). The immediacy bias may be partly caused by immediate emotion's salience, and by the greater availability of information about immediate compared with previous emotion. Consistent with emotional salience, when people experienced new emotions, they perceived previous emotions as less intense than they did initially (Studies 3 and 5)-a change in perception that did not occur when people did not experience a new immediate emotion (Study 2). Consistent with emotional availability, reminding people that information about emotions naturally decays from memory reduced the immediacy bias by making previous emotions seem more intense (Study 4). Discussed are implications for psychological theory and other judgments and behaviors.

    Faces drive our social interactions. A vast literature suggests an interaction between gender and emotional face perception, with studies using different methodologies demonstrating that the gender of a face can affect how emotions are processed. However, how different is our perception of affective male and female faces? Furthermore, how does our current affective state when viewing faces influence our perceptual biases? We presented participants with a series of faces morphed along an emotional continuum from happy to angry. Participants judged each face morph as either happy or angry. We determined each participant’s unique emotional ‘neutral’ point, defined as the face morph judged to be perceived equally happy and angry, separately for male and female faces. We also assessed how current state affect influenced these perceptual neutral points. Our results indicate that, for both male and female participants, the emotional neutral point for male faces is perceptually biased to be happier than for female faces. This bias suggests that more happiness is required to perceive a male face as emotionally neutral, i.e., we are biased to perceive a male face as more negative. Interestingly, we also find that perceptual biases in perceiving female faces are correlated with current mood, such that positive state affect correlates with perceiving female faces as happier, while we find no significant correlation between negative state affect and the perception of facial emotion. Furthermore, we find reaction time biases, with slower responses for angry male faces compared to angry female faces. PMID:27733839

  13. A Review on the Computational Methods for Emotional State Estimation from the Human EEG

    2013-01-01

    A growing number of affective computing researches recently developed a computer system that can recognize an emotional state of the human user to establish affective human-computer interactions. Various measures have been used to estimate emotional states, including self-report, startle response, behavioral response, autonomic measurement, and neurophysiologic measurement. Among them, inferring emotional states from electroencephalography (EEG) has received considerable attention as EEG could directly reflect emotional states with relatively low costs and simplicity. Yet, EEG-based emotional state estimation requires well-designed computational methods to extract information from complex and noisy multichannel EEG data. In this paper, we review the computational methods that have been developed to deduct EEG indices of emotion, to extract emotion-related features, or to classify EEG signals into one of many emotional states. We also propose using sequential Bayesian inference to estimate the continuous emotional state in real time. We present current challenges for building an EEG-based emotion recognition system and suggest some future directions.   PMID:23634176

    This manuscript summarizes the proceedings of the symposium entitled, “Stress, Palatable Food and Reward”, that was chaired by Drs. Linda Rinaman and Yvonne Ulrich-Lai at the 2014 Neurobiology of Stress Workshop held in Cincinnati, OH. This symposium comprised research presentations by four neuroscientists whose work focuses on the biological bases for complex interactions among stress, food intake and emotion. First, Dr. Ulrich-Lai describes her rodent research exploring mechanisms by which the rewarding properties of sweet palatable foods confer stress relief. Second, Dr. Stephanie Fulton discusses her work in which excessive, long-term intake of dietary lipids, as well as their subsequent withdrawal, promotes stress-related outcomes in mice. Third, Dr. Mark Wilson describes his group’s research examining the effects of social hierarchy-related stress on food intake and diet choice in group-housed female rhesus macaques, and compared the data from monkeys to results obtained in analogous work using rodents. Lastly, Dr. Gorica Petrovich discusses her research program that is aimed at defining cortical–amygdalar–hypothalamic circuitry responsible for curbing food intake during emotional threat (i.e., fear anticipation) in rats. Their collective results reveal the complexity of physiological and behavioral interactions that link stress, food intake and emotional state, and suggest new avenues of research to probe the impact of genetic, metabolic, social, experiential, and environmental factors.

    This study examined emotional modulation of word processing, showing that the recognition potential (RP), an ERP index of word recognition, could be modulated by different emotional states. In the experiment, participants were instructed to compete with pseudo-competitors, and via manipulation of the outcome of this competition, they were situated in neutral, highly positive, slightly positive, highly negative or slightly negative emotional states. They were subsequently asked to judge whether the referent of a word following a series of meaningless character segmentations was an animal or not. The emotional induction task and the word recognition task were alternated. Results showed that 1) compared with the neutral emotion condition, the peak latency of the RP under different emotional states was earlier and its mean amplitude was smaller, 2) there was no significant difference between RPs elicited under positive and negative emotional states in either the mean amplitude or latency, and 3) the RP was not affected by different degrees of positive emotional states. However, compared to slightly negative emotional states, the mean amplitude of the RP was smaller and its latency was shorter in highly negative emotional states over the left hemisphere but not over the right hemisphere. The results suggest that emotional states influence word processing.

    Depressive symptomatology is associated with impaired recognition of emotion. Previous investigations have predominantly focused on emotion recognition of static facial expressions neglecting the influence of social interaction and critical contextual factors. In the current study, we investigated how youth and maternal symptoms of depression may be associated with emotion recognition biases during familial interactions across distinct contextual settings. Further, we explored if an individual's current emotional state may account for youth and maternal emotion recognition biases. Mother-adolescent dyads (N = 128) completed measures of depressive symptomatology and participated in three family interactions, each designed to elicit distinct emotions. Mothers and youth completed state affect ratings pertaining to self and other at the conclusion of each interaction task. Using multiple regression, depressive symptoms in both mothers and adolescents were associated with biased recognition of both positive affect (i.e., happy, excited) and negative affect (i.e., sadness, anger, frustration); however, this bias emerged primarily in contexts with a less strong emotional signal. Using actor-partner interdependence models, results suggested that youth's own state affect accounted for depression-related biases in their recognition of maternal affect. State affect did not function similarly in explaining depression-related biases for maternal recognition of adolescent emotion. Together these findings suggest a similar negative bias in emotion recognition associated with depressive symptoms in both adolescents and mothers in real-life situations, albeit potentially driven by different mechanisms.

    Typically in the laboratory, cognitive and emotional processes are studied separately or as a stream of fleeting emotional stimuli embedded within a cognitive task. Yet in life, thoughts and actions often occur in more lasting emotional states of arousal. The current study examines the impact of emotions on actions using a novel behavioral paradigm and functional neuroimaging to assess cognitive control under sustained states of threat (anticipation of an aversive noise) and excitement (anticipation of winning money). Thirty-eight healthy adult participants were scanned while performing an emotional go/no-go task with positive (happy faces), negative (fearful faces), and neutral (calm faces) emotional cues, under threat or excitement. Cognitive control performance was enhanced during the excited state relative to a nonarousing control condition. This enhanced performance was paralleled by heightened activity of frontoparietal and frontostriatal circuitry. In contrast, under persistent threat, cognitive control was diminished when the valence of the emotional cue conflicted with the emotional state. Successful task performance in this conflicting emotional condition was associated with increased activity in the posterior cingulate cortex, a default mode network region implicated in complex processes such as processing emotions in the context of self and monitoring performance. This region showed positive coupling with frontoparietal circuitry implicated in cognitive control, providing support for a role of the posterior cingulate cortex in mobilizing cognitive resources to improve performance. These findings suggest that emotional states of arousal differentially modulate cognitive control and point to the potential utility of this paradigm for understanding effects of situational and pathological states of arousal on behavior.

    Research has shown that people often exert control over their emotions. By modulating expressions, reappraising feelings, and redirecting attention, they can regulate their emotional experience. These findings have contributed to a blurring of the traditional boundaries between cognitive and emotional processes, and it has been suggested that emotional signals are produced in a goal-directed way and monitored for errors like other intentional actions. However, this interesting possibility has never been experimentally tested. To this end, we created a digital audio platform to covertly modify the emotional tone of participants’ voices while they talked in the direction of happiness, sadness, or fear. The result showed that the audio transformations were being perceived as natural examples of the intended emotions, but the great majority of the participants, nevertheless, remained unaware that their own voices were being manipulated. This finding indicates that people are not continuously monitoring their own voice to make sure that it meets a predetermined emotional target. Instead, as a consequence of listening to their altered voices, the emotional state of the participants changed in congruence with the emotion portrayed, which was measured by both self-report and skin conductance level. This change is the first evidence, to our knowledge, of peripheral feedback effects on emotional experience in the auditory domain. As such, our result reinforces the wider framework of self-perception theory: that we often use the same inferential strategies to understand ourselves as those that we use to understand others.

    Full Text Available Working memory (WM capacity is associated with various emotional aspects, including states of depression and stress, reactions to emotional stimuli, and regulatory behaviors. We have previously investigated the effects of WM training (WMT on cognitive functions and brain structures. However, the effects of WMT on emotional states and related neural mechanisms among healthy young adults remain unknown. In the present study, we investigated these effects in young adults who underwent WMT or received no intervention for 4 weeks. Before and after the intervention, subjects completed self-report questionnaires related to their emotional states and underwent scanning sessions in which brain activities related to negative emotions were measured. Compared with controls, subjects who underwent WMT showed reduced anger, fatigue, and depression. Furthermore, WMT reduced activity in the left posterior insula during tasks evoking negative emotion, which was related to anger. It also reduced activity in the left frontoparietal area. These findings show that WMT can reduce negative mood and provide new insight into the clinical applications of WMT, at least among subjects with preclinical-level conditions.

An experimental procedure was implemented conforming to International Affective Picture System guidelines and incorporating the Self-Assessment Manikin test. Thirty students participated in the experiment. The stimulus was a short paragraph of text for which any content, emotion, and/or domain dependent information was excluded. The Analysis of Variance revealed the dependency of (a all the three emotional dimensions on font size and font/background color combinations and (b the Pleasure dimension on font type and font style. We introduce a set of mapping rules showing how PAD vary on the discrete values of font style and font type elements. Moreover, we introduce a set of equations describing the PAD dimensions' dependency on font size. This novel model can contribute to the automated reader's emotional state extraction in order, for example, to enhance the acoustic rendition of the documents, utilizing text-to-speech synthesis.

    Understanding the role of emotional states is critical for predicting the kind of decisions people will make in risky situations. Currently, there is little understanding as to how emotion influences decision-making in situations such as terrorist attacks, natural disasters, pandemics, and combat. To help address this, we used behavioral and neuroimaging methods to examine how emotion states and traits influence decisions. Specifically, this study used a wheel of fortune behavioral task and functional magnetic resonance imaging (fMRI) to examine the effects of emotional states and traits on decision-making pertaining to the degree of risk people are willing to make in specific situations. The behavioral results are reported here. The neural data requires additional time to analyze and will be reported at a future date. Biases caused by emotion states and traits were found regarding the likelihood of making risky decisions. The behavioral results will help provide a solid empirical foundation for modeling the effects of emotion on decision in risky situations.

    Full Text Available The current study was evaluated difference anxiety states at information processing in the electroencephalography (EEG under emotional stimuli for smartphone. Twenty-three healthy subjects were assessed for their anxiety states using The State Trait Anxiety Inventory (STAI and divided to two groups: low anxiety (I, II or high anxiety (III and IV, V group. EEG was measured under emotionally audio-visual stimuli (resting and pleasant, unpleasant sessions and emotionally sentence stimuli (pleasant sentence, unpleasant sentence sessions using emotionally audio-visual stimuli and emotionally sentence stimuli and analyzed using propagation speed analysis. The propagation speed of the low anxiety group at medial coronal in resting stimuli for all time was higher than those of high anxiety group, and that of the low anxiety group at medial sagittal in unpleasant stimuli for 60-150 seconds and those in unpleasant stimuli for 0-30, 60-150 seconds was higher than those of high anxiety group. The propagation speed for 150 seconds of all stimuli in the low anxiety group had a significantly higher than propagation speed for that in the high anxiety group. These events suggest that information processes concerning the emotional stimuli in the brain is differ based on the anxiety state of the subject.

    2010-01-01

    This paper presents our investigations on emotional state categorization from speech signals with a psychologically inspired computational model against human performance under the same experimental setup. Based on psychological studies, we propose a multistage categorization strategy which allows establishing an automatic categorization model flexibly for a given emotional speech categorization task. We apply the strategy to the Serbian Emotional Speech Corpus (GEES) and the Danish Emotional Speech Corpus (DES), where human performance was reported in previous psychological studies. Our work is the first attempt to apply machine learning to the GEES corpus where the human recognition rates were only available prior to our study. Unlike the previous work on the DES corpus, our work focuses on a comparison to human performance under the same experimental settings. Our studies suggest that psychology-inspired systems yield behaviours that, to a great extent, resemble what humans perceived and their performance ...

  16. Facial Expression Generation from Speaker's Emotional States in Daily Conversation

    Mori, Hiroki; Ohshima, Koh

    A framework for generating facial expressions from emotional states in daily conversation is described. It provides a mapping between emotional states and facial expressions, where the former is represented by vectors with psychologically-defined abstract dimensions, and the latter is coded by the Facial Action Coding System. In order to obtain the mapping, parallel data with rated emotional states and facial expressions were collected for utterances of a female speaker, and a neural network was trained with the data. The effectiveness of proposed method is verified by a subjective evaluation test. As the result, the Mean Opinion Score with respect to the suitability of generated facial expression was 3.86 for the speaker, which was close to that of hand-made facial expressions.

    The present study compared the effects of two different music interventions on changes in emotional states before and during running, and also explored effects of music interventions upon performance outcome. Volunteer participants (n = 65) who regularly listened to music when running registered online to participate in a three-stage study. Participants attempted to attain a personally important running goal to establish baseline performance. Thereafter, participants were randomly assigned to either a self-selected music group or an Audiofuel music group. Audiofuel produce pieces of music designed to assist synchronous running. The self-selected music group followed guidelines for selecting motivating playlists. In both experimental groups, participants used the Brunel Music Rating Inventory-2 (BMRI-2) to facilitate selection of motivational music. Participants again completed the BMRI-2 post- intervention to assess the motivational qualities of Audiofuel music or the music they selected for use during the study. Results revealed no significant differences between self-selected music and Audiofuel music on all variables analyzed. Participants in both music groups reported increased pleasant emotions and decreased unpleasant emotions following intervention. Significant performance improvements were demonstrated post-intervention with participants reporting a belief that emotional states related to performance. Further analysis indicated that enhanced performance was significantly greater among participants reporting music to be motivational as indicated by high scores on the BMRI-2. Findings suggest that both individual athletes and practitioners should consider using the BMRI-2 when selecting music for running. Key pointsListening to music with a high motivational quotient as indicated by scores on the BMRI-2 was associated with enhanced running performance and meta-emotional beliefs that emotions experienced during running helped performance.Beliefs on the

  18. Animal emotions, behaviour and the promotion of positive welfare states.

    Mellor, D J

    2012-01-01

    This paper presents a rationale that may significantly boost the drive to promote positive welfare states in animals. The rationale is based largely, but not exclusively, on an experimentally supported neuropsychological understanding of relationships between emotions and behaviour, an understanding that has not yet been incorporated into animal welfare science thinking. Reference is made to major elements of the neural/cognitive foundations of motivational drives that energise and direct particular behaviours and their related subjective or emotional experiences. These experiences are generated in part by sensory inputs that reflect the animal's internal functional state and by neural processing linked to the animal's perception of its external circumstances. The integrated subjective or emotional outcome of these inputs corresponds to the animal's welfare status. The internally generated subjective experiences represent motivational urges or drives that are predominantly negative and include breathlessness, thirst, hunger and pain. They are generated by, and elicit specific behaviours designed to correct, imbalances in the animal's internal functional state. Externally generated subjective experiences are said to be integral to the operation of interacting 'action-orientated systems' that give rise to particular behaviours and their negative or positive emotional contents. These action-orientated systems, described in neuropsychological terms, give rise to negative emotions that include fear, anger and panic, and positive emotions that include comfort, vitality, euphoria and playfulness. It is argued that early thinking about animal welfare management focused mainly on minimising disturbances to the internal functional states that generate associated unpleasant motivational urges or drives. This strategy produced animal welfare benefits, but at best it could only lift a poor net welfare status to a neutral one. In contrast, strategies designed to manipulate the

    The aim of this paper is to identify the common neural signatures based on which the positive and negative valence of human emotions across multiple subjects can be reliably discriminated. The brain activity is observed via Event Related Potentials (ERPs). ERPs are transient components in the Electroencephalography (EEG) generated in response to a stimulus. ERPs were collected while subjects were viewing images with positive or negative emotional content. Building inter-subject discrimination models is a challenging problem due to the high ERPs variability between individuals. We propose to solve this problem with the aid of the Echo State Networks (ESN) as a general framework for extracting the most relevant discriminative features between multiple subjects. The original feature vector is mapped into the reservoir feature space defined by the number of the reservoir equilibrium states. The dominant features are extracted iteratively from low dimensional combinations of reservoir states. The relevance of the new feature space was validated by experiments with standard supervised and unsupervised machine learning techniques. From one side this proof of concept application enhances the usability context of the reservoir computing for high dimensional static data representations by low-dimensional feature transformation as functions of the reservoir states. From other side, the proposed solution for emotion valence detection across subjects is suitable for brain studies as a complement to statistical methods. This problem is important because such decision making systems constitute "virtual sensors" of hidden emotional states, which are useful in psychology science research and clinical applications.

    Full Text Available Ebooks of the future may respond to the emotional experience of the reader. (Neuro- physiological measures could capture a reader’s emotional state and use this to enhance the reading experience by adding matching sounds or to change the storyline therewith creating a hybrid art form in between literature and gaming. We describe the theoretical foundation of the emotional and creative brain and review the neurophysiological indices that can be used to drive future ebook interactivity in a real life situation. As a case study, we report the neurophysiological measurements of a bestselling author during nine days of writing which can potentially be used later to compare them to those of the readers. In designated calibration blocks, the artist wrote emotional paragraphs for emotional (IAPS pictures. Analyses showed that we can reliably distinguish writing blocks from resting but we found no reliable differences related to the emotional content of the writing. The study shows that measurements of EEG, heart rate (variability, skin conductance, facial expression and subjective ratings can be done over several hours a day and for several days in a row. In follow-up phases, we will measure 300 readers with a similar setup.

    Full Text Available While emotion dysregulation has been investigated as a key variable in the development and persistence of personality psychopathology, few studies have explored state emotion dysregulation among individuals with personality disorders (PDs. The current study addresses this void in the literature through a laboratory investigation of state emotion dysregulation among participants with and without PDs. To facilitate this goal, participants were matched to pairs based on similar personality features and were randomized to one of two behavioral analogues; either the Paced Auditory Serial Addition Task-Computerized (PASAT-C or an interpersonally based mood induction. As hypothesized, PD participants in the PASAT-C reported significantly more difficulty with impulsivity and emotion regulation strategies. Contrary to expectations, the PD group in the interpersonal task demonstrated significantly less difficulty with non-acceptance of emotion and emotional clarity and significantly greater positive affect compared to non-PD participants. Implications for these findings and directions for future research are discussed.

    Full Text Available Following from previous research on intensity bias and the accessibility model of emotional self-report, the present study examined the role of emotional exhaustion in explaining the discrepancy in teachers' reports of their trait (habitual versus state (momentary, "real" emotions. Trait reports (habitual emotions, exhaustion were assessed via trait questionnaires, and state reports (momentary emotions were assessed in real time via the experience sampling method by using personal digital assistants (N = 69 high school teachers; 1,089 measures within teachers. In line with our assumptions, multi-level analyses showed that, as compared to the state assessment, teachers reported higher levels of habitual teaching-related emotions of anger, anxiety, shame, boredom, enjoyment, and pride. Additionally, the state-trait discrepancy in self-reports of negative emotions was accounted for by teachers' emotional exhaustion, with high exhaustion levels corresponding with a greater state-trait discrepancy. Exhaustion levels did not moderate the state-trait discrepancy in positive emotions indicating that perceived emotional exhaustion may reflect identity-related cognitions specific to the negative belief system. Implications for research and educational practice are discussed.

    Full Text Available The prefrontal cortex is involved in mood and emotional processing. In patients suffering from depression, the left dorsolateral prefrontal cortex is hypoactive, while activity of the right dorsolateral prefrontal cortex is enhanced. Counterbalancing these pathological excitability alterations by repetitive transcranial magnetic stimulation (rTMS or transcranial direct current stimulation (tDCS improves mood in these patients. In healthy subjects, however, rTMS of the same areas has no major effect, and the effects of tDCS are mixed. We aimed to evaluate the effects of prefrontal tDCS on mood and mood-related cognitive processing in healthy humans. In a first study, we administered excitability-enhancing anodal, excitability-diminishing cathodal and placebo tDCS to the left dorsolateral prefrontal cortex, combined with antagonistic stimulation of the right frontopolar cortex, and tested acute mood changes by an adjective checklist. Subjective mood was not influenced by tDCS. Emotional face identification, however, which was explored in a second experiment, was subtly improved by a tDCS-driven excitability modulation of the prefrontal cortex, markedly by anodal tDCS of the left dorsolateral prefrontal cortex for positive emotional content. We conclude that tDCS of the prefrontal cortex improves mood processing in healthy subjects, but does not influence subjective mood state.

    Irradiation of foodstuffs causes undesirable changes in oxylabile vitamins and lipids, the release of smelly products or the softening of fibres even at very low doses. A combination of irradiation with heating or freezing is used in the attempt to mitigate these unfavourable effects. Gamma and x rays are used for irradiation, beta rays are being tried which inactivate microorganisms on the surface of the foodstuff and interfere only very little with the internal structure of the foodstuff. In case dose rates over 1 kGy are used it will be necessary to test the toxicity and mutagenicity of the irradiated foodstuff on laboratory animals. Next to undesirable changes in the sensory properties and nutritional value of the foodstuffs there are also the high costs of irradiation which amount to 5 to 10% of the price of the foodstuff. Currently, irradiation is permitted for the preservation of foodstuffs in 21 countries of the world.

    2013-12-01

    Case definitions are critical in epidemiologic research. However, modern disease indicators must now consider complex data from gene-based research along with traditional clinical parameters. Rosacea is a skin disorder with multiple signs and symptoms. In individuals, these features may be multiple or one may predominate. While studies on the epidemiology of rosacea have previously been sparse, there has been a recent increase in research activity. A broader body of epidemiological information that includes a greater variety of countries beyond Northern Europe and general population-based demographics is needed. As there are operational issues in current case definitions of rosacea subtypes--rationalization and standardization--universal consistent applications in future research is also imperative. Further improvement in disease definition combining new research information along with clinical pragmatism should increase the accuracy of rosacea case ascertainment and facilitate further epidemiological research.

Twenty-three healthy subjects were assessed for their anxiety states using The State Trait Anxiety Inventory (STAI) and divided into two groups: low anxiety (I, II) or high anxiety (III and IV, V). An EEG was performed while the participant was presented with emotionally laden audiovisual stimuli (resting, pleasant, and unpleasant sessions) and emotionally laden sentence stimuli (pleasant sentence, unpleasant sentence sessions) and EEG data was analyzed using propagation speed analysis. The propagation speed of the low anxiety group at the medial coronal for resting stimuli for all time segments was higher than those of high anxiety group. The low anxiety group propagation speeds at the medial sagittal for unpleasant stimuli in the 0-30 and 60-150 s time frames were higher than those of high anxiety group. The propagation speeds at 150 s for all stimuli in the low anxiety group were significantly higher than the correspondent propagation speeds of the high anxiety group. These events suggest that neural information processes concerning emotional stimuli differ based on current anxiety state.

    Objectives Recently, there has been increasing interest in preventing and managing diseases both inside and outside medical institutions, and these concerns have supported the development of the individual Personal Health Record (PHR). Thus, the current study created a mobile platform called “Mind Mirror” to evaluate psychological and physical conditions and investigated whether PHRs would be a useful tool for assessment of the dynamic relationship between the emotional and physical conditions of an individual. Methods Mind Mirror was used to collect 30 days of observational data about emotional valence and the physical states of pain and fatigue from 20 healthy participants, and these data were used to analyze the dynamic relationship between emotional and physical conditions. Additionally, based on the cross-correlations between these three parameters, a multilevel multivariate regression model (mixed linear model [MLM]) was implemented. Results The strongest cross-correlation between emotional and physical conditions was at lag 0, which implies that emotion and body condition changed concurrently. In the MLM, emotional valence was negatively associated with fatigue (β =−0.233, Ppain (β =0.250, Ppain was positively associated with fatigue (β =0.398, Pemotional valence and one’s physical condition negatively influenced one another, while fatigue and pain positively affected each other. These findings suggest that the mind and body interact instantaneously, in addition to providing a possible solution for the recording and management of health using a PHR on a daily basis.

    The emotional state can influence decision-making under ambiguity. Cognitive bias tests (CBT) proved to be a promising indicator of the affective valence of animals in a context of farm animal welfare. Although it is well-known that humans can influence the intensity of fear and reactions of animals, research on cognitive bias often focusses on housing and management conditions and neglects the role of humans on emotional states of animals. The present study aimed at investigating whether humans can modulate the emotional state of weaned piglets. Fifty-four piglets received a chronic experience with humans: gentle (GEN), rough (ROU) or minimal contact (MIN). Simultaneously, they were individually trained on a go/no-go task to discriminate a positive auditory cue, associated with food reward in a trough, from a negative one, associated with punishments (e.g. water spray). Independently of the treatment (P = 0.82), 59% of piglets completed the training. Successfully trained piglets were then subjected to CBT, including ambiguous cues in presence or absence of a human observer. As hypothesized, GEN piglets showed a positive judgement bias, as shown by their higher percentage of go responses following an ambiguous cue compared to ROU (P = 0.03) and MIN (P = 0.02) piglets, whereas ROU and MIN piglets did not differ (P > 0.10). The presence of an observer during CBT did not modulate the percentage of go responses following an ambiguous cue (P > 0.10). However, regardless of the treatment, piglets spent less time in contact with the trough following positive cues during CBT in which the observer was present than absent (P < 0.0001). This study originally demonstrates that the nature of a chronic experience with humans can induce a judgement bias indicating that the emotional state of farm animals such as piglets can be affected by the way humans interact with them.

    Full Text Available Currently, psychosocial factors, stress and mental exhaustion are considered by WHO experts and the International Labour Organization as an important new factor affecting the health, working capacity, training and career. Young generation, especially students, who are an industrial and intellectual potential of the country can be attributed to the risk group because of the extremely high burden of adaptation. The intensity and tension of modern life at a psychological level preceding the occurrence of negative emotional experiences and stress reactions that, accumulating, cause the formation of depressions. The aim of the study was to examine the level of psycho-emotional stress in the junior students of medical university. The observations of the medical students of the second year of study were performed. To determine the psycho-emotional stress we have used adaptive varint of H.Ayzenko method that include an anxiety, frustration, aggressiveness and rigidity, through questionnaires. According to a survey results of the state of psycho-emotional state low levels of stress resistance were found in students in learning activities, indicating that students are exposed to the negative impact of the environment. It should also be noted that the level of emotional condition of students depends on the personal experience of stressful situations that arise in students’ lives.

    The development of ecologically valid procedures for collecting reliable and unbiased emotional data towards computer interfaces with social and affective intelligence targeting patients with mental disorders. Following its development, presented with, the Athens Emotional States Inventory (AESI) proposes the design, recording and validation of an audiovisual database for five emotional states: anger, fear, joy, sadness and neutral. The items of the AESI consist of sentences each having content indicative of the corresponding emotion. Emotional content was assessed through a survey of 40 young participants with a questionnaire following the Latin square design. The emotional sentences that were correctly identified by 85% of the participants were recorded in a soundproof room with microphones and cameras. A preliminary validation of AESI is performed through automatic emotion recognition experiments from speech. The resulting database contains 696 recorded utterances in Greek language by 20 native speakers and has a total duration of approximately 28 min. Speech classification results yield accuracy up to 75.15% for automatically recognizing the emotions in AESI. These results indicate the usefulness of our approach for collecting emotional data with reliable content, balanced across classes and with reduced environmental variability.

    The authors describe the conversion of an Endeco-174 current meter to a solid-state recording current meter. A removable solid-state module was designed to fit in the space originally occupied by an 8-track tape cartridge. The module contains a CPU and 128 kilobytes of nonvolatile CMOS memory. The solid-state module communicates with any terminal or computer using an RS-232C interface at 4800 baud rate. A primary consideration for conversion was to keep modifications of the current meter to a minimum. The communication protocol was designed to emulate the Endeco tape translation unit, thus the need for a translation unit was eliminated and the original data reduction programs can be used without any modification. After conversion, the data recording section of the current meter contains no moving parts; the storage capacity of the module is equivalent to that of the original tape cartridge.

    Current literature suggests that theory of mind (ToM) and recognition of facial emotion are impaired in behavioral variant frontotemporal dementia (bvFTD). In contrast, studies suggest that ToM is spared in Alzheimer disease (AD). However, there is controversy whether recognition of emotion in faces is impaired in AD. This study challenges the concepts that ToM is preserved in AD and that recognition of facial emotion is impaired in bvFTD. ToM, recognition of facial emotion, and identification of emotions associated with video vignettes were studied in bvFTD, AD, and normal controls. ToM was assessed using false-belief and visual perspective-taking tasks. Identification of facial emotion was tested using Ekman and Friesen's pictures of facial affect. After adjusting for relevant covariates, there were significant ToM deficits in bvFTD and AD compared with controls, whereas neither group was impaired in the identification of emotions associated with video vignettes. There was borderline impairment in recognizing angry faces in bvFTD. Patients with AD showed significant deficits on false belief and visual perspective taking, and bvFTD patients were impaired on second-order false belief. We report novel findings challenging the concepts that ToM is spared in AD and that recognition of facial emotion is impaired in bvFTD.

    Attentional control theory suggests that heightened anxiety, whether due to trait or state factors, causes an increased vulnerability to distraction even when the distracters are emotionally neutral. Recent passive oddball studies appear to support this theory in relation to the distraction caused by emotionally neutral sounds. However such studies have manipulated emotional state via the content of task stimuli, thus potentially confounding changes in emotion with differences in task demands. To identify the effect of anxiety on the distraction caused by emotionally neutral sounds, 50 participants completed a passive oddball task requiring emotionally neutral sounds to be ignored. Crucially, state anxiety was manipulated independent of the task stimuli (via unrelated audiovisual stimuli) thus removing confounds relating to task demands. Neither state or trait anxiety was found to influence the susceptibility to distraction by emotionally neutral sounds. These findings contribute to the ongoing debate concerning the impact of emotion on attention.

    Perspective displays (e.g., CDTI) are commonly used as decision aids in environments characterized by periods of high emotional arousal (e.g., terrain enhanced primary flight displays). However, little attention has been devoted to understanding how emotional state, independently or in conjunction with other perceptual factors (e.g., pictorial depth cues), can impact perceptual judgments. Preliminary research suggests that induced emotional state (positive or negative) adversely impacts size comparisons in perspective displays (Tran & Raddatz, 2006). This study further investigated how size comparisons are affected by emotional state and pictorial depth cues while attenuating the limitations of the Tran & Raddatz (2006) study. Results confirmed that observers do make slower judgments under induced emotional state. However, observers under negative emotional state showed higher sensitivity (d’) and required more evidence to respond that a size difference exists (response bias) than observers under positive emotional state. Implications for display design and human performance are discussed.

    Full Text Available The article describes the results of a study of the emotional state of preschool children who are in difficult circumstances and in social shelter. The study involved 10 children participated (6 boys and 4 girls aged 4-6 years of social shelter (Independent institution of social service of the population of the Tyumen Region Center for Social Assistance to Families and Children "Maria" Tyumen. The control group consisted of children who are brought up in a family and attending kindergarten number 123 Tyumen, in the amount of 16 people: 9 girls and 7 boys. The study of emotional states of preschoolers was conducted using projective techniques drawing tests "House Tree Person" in modification of R.F. Belyauskayte. To determine the anxiety of children in relation to a number of typical life situations of communication with other people was used the projective technique "Test of anxiety" of R. Temml, M. Dorki, V. Amena, obtained diagnostic data were subjected to qualitative and quantitative analysis. Mathematical analysis of the significance of differences was determined by calculating the U Mann Whitney. Preschoolers from social shelter in contrast to the control group of children have higher levels of anxiety are the most intense  and  stressful  relations in  the  system  "childchild." They are closed, can not be influenced, so they can be naughty, which leads to difficulties interaction and understanding of others, so they need an individual approach on the part of the teacher in the educational process. These children have difficulty communicating, which are shown in the restriction or denial of contact with others, which causes problems with the development of communication skills and experience of negative emotions.

    A one hypothesis to explain some vestibular peripheral disorders is their association with life style. Thus, studies with young adults are relevant. to analyze the prevalence of dynamic balance alterations in young adults and their possible association with life style variables, health and negative emotional states (since they can impact the outcome). we carried out a non-probabilistic cross-sectional, clinical-retrospective study with young adults (18-32 years of age) from a university with 751 individuals, with a mean age of 22.45+/- 3.32 years. Life style, health and negative emotional states (NES) variables - depression, stress and anxiety, were collected by means of an interview. The Unterberger test was used in order to check for indications of dynamic balance alterations. Individuals with altered dynamic balance (ADB) were compared to those without these alterations (controls). From our sample, 642 (83.6%) had less than 45 masculine of deviation, while 109 (14.2%) had greater than 45 masculine deviation and were the considered with ADB. The ADB group had a greater prevalence of smoking, alcohol abuse/dependence, high blood pressure and NES. the study highlights the occurrence of ADB which needs to be corroborated in future studies.

    This study systematically examined state-level laws protecting breastfeeding, including their current status and historical development, as well as identified gaps across US states and regions. The National Conference of State Legislatures summarised breastfeeding laws for 50 states and DC as of September 2010, which we updated through May 2011. We then searched LexisNexis and Westlaw to find the full text of laws, recording enactment dates and definitions. Laws were coded into five categories: (1) employers are encouraged or required to provide break time and private space for breastfeeding employees; (2) employers are prohibited from discriminating against breastfeeding employees; (3) breastfeeding is permitted in any public or private location; (4) breastfeeding is exempt from public indecency laws; and (5) breastfeeding women are exempt from jury duty. By May 2011, 1 state had enacted zero breastfeeding laws, 10 had one, 22 had two, 12 had three, 5 had four and 1 state had laws across all five categories. While 92% of states allowed mothers to breastfeed in any location and 57% exempted breastfeeding from indecency laws, 37% of states encouraged or required employers to provide break time and accommodations, 24% offered breastfeeding women exemption from jury duty and 16% prohibited employment discrimination. The Northeast had the highest proportion of states with breastfeeding laws and the Midwest had the lowest. Breastfeeding outside the home is protected to varying degrees depending on where women live; this suggests that many women are not covered by comprehensive laws that promote breastfeeding. © 2012 John Wiley & Sons Ltd.

    Studies using transcranial direct current stimulation (tDCS) of prefrontal cortex to improve symptoms of depression have had mixed results. We examined whether using tDCS to change the balance of activity between left and right dorsolateral prefrontal cortex (DLPFC) can alter mood and memory retrieval of emotional material in healthy volunteers. Participants memorised emotional images, then tDCS was applied bilaterally to DLPFC while they performed a stimulus-response compatibility task. Participants were then presented with a set of images for memory retrieval. Questionnaires to examine mood and motivational state were administered at the beginning and end of each session. Exploratory data analyses showed that the polarity of tDCS to DLPFC influenced performance on a stimulus-response compatibility task and this effect was dependent on participants' prior motivational state. However, tDCS polarity had no effect on the speed or accuracy of memory retrieval of emotional images and did not influence positive or negative affect. These findings suggest that the balance of activity between left and right DLPFC does not play a critical role in the mood state of healthy individuals. We suggest that the efficacy of prefrontal tDCS depends on the initial activation state of neurons and future work should take this into account.

    Internationally adopted postinstitutionalized (PI) children are at risk for lower levels of emotion understanding. This study examined how postadoption parenting influences emotion understanding and whether lower levels of emotion understanding are associated with behavior problems. Emotion understanding and parent mental state language were assessed in 3-year-old internationally adopted PI children (N = 25), and comparison groups of children internationally adopted from foster care (N = 25) and nonadopted (NA) children (N = 36). At 5.5-year follow-up, PI children had lower levels of emotion understanding than NA children, a group difference not explained by language. In the total sample, parent mental state language at age 3 years predicted 5.5-year emotion understanding after controlling for child language ability. The association of parent mental state language and 5.5-year emotion understanding was moderated by adoption status, such that parent mental state language predicted 5.5-year emotion understanding for the internationally adopted children, but not for the NA children. While postadoption experience does not erase negative effects of early deprivation on emotion understanding, results suggest that parents can promote emotion understanding development through mental state talk. At 5.5 years, PI children had more internalizing and externalizing problems than NA children, and these behavioral problems related to lower levels of emotion understanding.

  9. Emotion, Cognition, and Mental State Representation in Amygdala and Prefrontal Cortex

    Salzman, C. Daniel; Fusi, Stefano

    2011-01-01

    Neuroscientists have often described cognition and emotion as separable processes implemented by different regions of the brain, such as the amygdala for emotion and the prefrontal cortex for cognition. In this framework, functional interactions between the amygdala and prefrontal cortex mediate emotional influences on cognitive processes such as decision-making, as well as the cognitive regulation of emotion. However, neurons in these structures often have entangled representations, whereby single neurons encode multiple cognitive and emotional variables. Here we review studies using anatomical, lesion, and neurophysiological approaches to investigate the representation and utilization of cognitive and emotional parameters. We propose that these mental state parameters are inextricably linked and represented in dynamic neural networks composed of interconnected prefrontal and limbic brain structures. Future theoretical and experimental work is required to understand how these mental state representations form and how shifts between mental states occur, a critical feature of adaptive cognitive and emotional behavior.

    The mechanisms through which current romantic relationship dysfunction develops in individuals with borderline personality disorder (BPD) symptoms are still unclear. One possible pathway may be childhood experiences of emotional invalidation by parents, which may result in the development of poor social problem-solving skills or cognitive responses such as splitting, which impair current romantic relationships. This study examines the relationship between features of BPD and current romantic relationship dysfunction, and demonstrates that perceived emotional invalidation by parents during childhood mediates the relationship between BPD features and current romantic relationship dysfunction. Structural equations modeling was used to test the hypothesized model in 758 young adults in an ethnically diverse community sample. The proposed model fit the data well; perceived childhood emotional invalidation partially mediated the relationship between features of BPD and romantic relationship dysfunction, even when controlling for the presence of a major depressive episode in the last year. The findings of this study suggest that individuals with features of BPD experience relationship dysfunction that cannot be accounted for by comorbid depression and that perceived childhood emotional invalidation may contribute to these problems.

Thus, the current study created a mobile platform called “Mind Mirror” to evaluate psychological and physical conditions and investigated whether PHRs would be a useful tool for assessment of the dynamic relationship between the emotional and physical conditions of an individual.Methods: Mind Mirror was used to collect 30 days of observational data about emotional valence and the physical states of pain and fatigue from 20 healthy participants, and these data were used to analyze the dynamic relationship between emotional and physical conditions. Additionally, based on the cross-correlations between these three parameters, a multilevel multivariate regression model (mixed linear model [MLM] was implemented.Results: The strongest cross-correlation between emotional and physical conditions was at lag 0, which implies that emotion and body condition changed concurrently. In the MLM, emotional valence was negatively associated with fatigue (β =-0.233, P<0.001, fatigue was positively associated with pain (β =0.250, P<0.001, and pain was positively associated with fatigue (β =0.398, P<0.001.Conclusion: Our study showed that emotional valence and one’s physical condition negatively influenced one another, while fatigue and pain positively affected each other.

    Emotion regulation is the process that adjusts the type or amount of emotion when we experience an emotional situation. The aim of this study was to reveal quantitative changes in brain activity during emotional information processing related to psychosomatic states and to determine electrophysiological features of neuroticism. Twenty-two healthy subjects (mean age 25 years, 14 males and 8 females) were registered. Electroencephalography (EEG) was measured during an emotional audiovisual memory task under three conditions (neutral, pleasant and unpleasant sessions). We divided the subjects into two groups using the Cornell Medical Index (CMI): (CMI-I: control group, n = 10: CMI-II, III or IV: neuroticism group, n = 12). We analyzed the digital EEG data using exact low-resolution brain electromagnetic tomography (eLORETA) current source density (CSD) and functional connectivity analysis in several frequency bands (δ, θ, α, β, γ and whole band). In all subjects, bilateral frontal α CSD in the unpleasant session increased compared to the pleasant session, especially in the control group (p neuroticism group was significantly higher than that of the control group in the full band at the amygdala and inferior temporal gyrus, and in the α band at the right temporal lobe (p neuroticism electrophysiologically, which may serve as a neurophysiological marker of this personality trait. © 2015 S.

    The aim of the study was to investigate influence of color hue saturation on emotional state of human. We use frontal EEG asymmetry to determine subject's emotional state. Our emotional stimuli summon opposite dynamics of frontal EEG asymmetry. Negative stimuli elicits decreasing of the value of frontal EEG asymmetry and positive stimuli increases the value of frontal EEG asymmetry in fronto-polar and frontal leads. Such dynamics of frontal EEG asymmetry point the emotional experience in accordance the stimulus modality. Blue and red color modification of stimuli leads changes in dynamics of frontal EEG asymmetry during presentation of emotional stimuli and after. In fact, that no one subject gave a report about color difference between stimuli during an experiment, we conclude that influence of color modification was unconscious. Our result shows the possibility of unconscious perception color modification to emotional state of human.

    2014-07-01

    We explored the meta-emotion philosophies of Indian immigrant mothers living in the Midwest region of the United States to expand the scarce literature on emotion socialization in diverse families. A total of 15 mothers of teen and preteen children participated in a meta-emotion interview, in which they were asked about their own and their children's experiences of anger, sadness, and fear. We analyzed interview responses through an open-ended phenomenological approach and found the following major themes: familial context of emotions, subtle communication of emotions, and an overarching philosophy centering on inevitability of negative emotions and the importance of moving on. Mothers differed in how well they believed that they could move on. Overall, the present findings demonstrate the role culture plays in emotional experiences of immigrant mothers and serve as a reminder that theories based on European American families might have limited applicability to other cultural and ethnic groups.

  1. Eat your troubles away: electrocortical and experiential correlates of food image processing are related to emotional eating style and emotional state.

    2014-02-01

    Emotional eating, a trait-like style of food intake in response to negative emotion states, represents an important aspect of overeating and eating related psychopathology. The mechanisms of emotional eating both on experiential and neuronal levels are not well delineated. We recorded event related potentials (ERPs) while individuals with high or low emotional eating style (HEE, n=25; LEE, n=20) viewed and rated pictures of high-caloric food during neutral state vs. negative idiosyncratic emotion induction. Craving ratings increased in HEE and decreased in LEE during negative relative to neutral states. ERPs to food pictures showed an enhanced late positive potential (LPP) over parieto-occipital regions for HEE compared to LEE. Emotional state modulated food picture evoked ERPs over right frontal regions in HEE only. This suggests that appetitive food processing is susceptible to both concurrent emotion and habitual eating style which is of relevance for overeating in healthy and abnormal eating.

    2006-10-01

    Previous research has been devoted to the study of perceptual (e.g., number of depth cues) and cognitive (e.g., instructional set) factors that influence veridical size perception in perspective displays. However, considering that perspective displays have utility in high workload environments that often induce high arousal (e.g., aircraft cockpits), the present study sought to examine the effect of observers’ emotional state on the ability to perceive and judge veridical size. Within a dual-task paradigm, observers’ ability to make accurate size judgments was examined under conditions of induced emotional state (positive, negative, neutral) and high and low workload. Results showed that participants in both positive and negative induced emotional states were slower to make accurate size judgments than those not under induced emotional arousal. Results suggest that emotional state is an important factor that influences visual performance on perspective displays and is worthy of further study.

    Noel, Corinna; Dando, Robin

    2015-12-01

    Taste perception can be modulated by a variety of extraneously applied influences, such as the manipulation of emotion or the application of acute stress. To evaluate the effect of more commonplace day-to-day emotional variation on taste function, taste intensity ratings and hedonic evaluations were collected from approximately 550 attendees following men's hockey games spanning the 2013-2014 season, a period encompassing 4 wins, 3 losses, and 1 tie. Since different outcomes at competitive sporting events are shown to induce varying affective response, this field study presented a unique environment to evaluate the effect of real-life emotional manipulations on our perception of taste, where previous research focused more on extraneous manipulation within a laboratory environment. Analysis revealed that positive emotions correlated with enhanced sweet and diminished sour intensities while negative emotions associated with heightened sour and decreased sweet tastes. Theoretically, both an increase in sweet and a decrease in sour taste intensity would drive acceptance of a great number of foods. Indeed, hedonic ratings for samples that were less liked (and parenthetically mostly sweet and sour in nature), selectively increased as positive affect grew, possibly due to the perceived decrease in sourness and increase in sweetness. The results of this field study indicate that emotional manipulations in the form of pleasantly or unpleasantly perceived real-life events can influence the intensity perception of taste, driving hedonics for less acceptable foods. These results suggest that such modulation of taste perception could play a role in emotional eating.

    Event-related potentials (ERPs) are a direct measure of neural activity and are ideally suited to study the time-course of attentional engagement with emotional and drug-related stimuli in addiction. In particular, the late positive potential (LPP) appears enhanced following cocaine-related compared to neutral stimuli in individuals with cocaine use disorders (CUD). However, previous studies have not directly compared cocaine-related to emotional stimuli while examining potential differences between abstinent and current cocaine users. The present study examined ERPs in 55 CUD (27 abstinent and 28 current users) and 29 matched healthy controls while they passively viewed pleasant, unpleasant, neutral, and cocaine-related pictures. To examine the time-course of attention to these stimuli, we analyzed both an early and later window in the LPP as well as the early posterior negativity (EPN), established in assessing motivated attention. Cocaine pictures elicited increased electrocortical measures of motivated attention in ways similar to affectively pleasant and unpleasant pictures in all CUD, an effect that was no longer discernible during the late LPP window for the current users. This group also exhibited deficient processing of the other emotional stimuli (early LPP window: pleasant pictures; late LPP window: pleasant and unpleasant pictures). Results were unique to the LPP and not EPN. Taken together, results support a relatively early attention bias to cocaine stimuli in cocaine addicted individuals further suggesting that recent cocaine use decreases such attention bias during later stages of processing but at the expense of deficient processing of other emotional stimuli.

  8. The voice of emotion across species: how do human listeners recognize animals' affective states?

    Directory of Open Access Journals (Sweden)

    Marina Scheumann

    Full Text Available Voice-induced cross-taxa emotional recognition is the ability to understand the emotional state of another species based on its voice. In the past, induced affective states, experience-dependent higher cognitive processes or cross-taxa universal acoustic coding and processing mechanisms have been discussed to underlie this ability in humans. The present study sets out to distinguish the influence of familiarity and phylogeny on voice-induced cross-taxa emotional perception in humans. For the first time, two perspectives are taken into account: the self- (i.e. emotional valence induced in the listener versus the others-perspective (i.e. correct recognition of the emotional valence of the recording context. Twenty-eight male participants listened to 192 vocalizations of four different species (human infant, dog, chimpanzee and tree shrew. Stimuli were recorded either in an agonistic (negative emotional valence or affiliative (positive emotional valence context. Participants rated the emotional valence of the stimuli adopting self- and others-perspective by using a 5-point version of the Self-Assessment Manikin (SAM. Familiarity was assessed based on subjective rating, objective labelling of the respective stimuli and interaction time with the respective species. Participants reliably recognized the emotional valence of human voices, whereas the results for animal voices were mixed. The correct classification of animal voices depended on the listener's familiarity with the species and the call type/recording context, whereas there was less influence of induced emotional states and phylogeny. Our results provide first evidence that explicit voice-induced cross-taxa emotional recognition in humans is shaped more by experience-dependent cognitive mechanisms than by induced affective states or cross-taxa universal acoustic coding and processing mechanisms.

  9. Russian electricity market. Current state and perspectives

    The Russian electricity market is currently in transition. The restructuring of the sector has been completed and former public vertically integrated monopolies have been unbundled and partly privatised. The government retained control in all the network companies, the system operator, nuclear generation, and hydro generation. The state retains control also via owner-ship in several TGCs and WGCs in the strategic regions of Moscow and Saint-Petersburg via the state owned gas monopoly Gazprom. The liberalization takes place within two price zones, Europe and Siberia, where more than 90%, 913 TWh in 2007, of Russian electricity consumption takes place. In the rest of Russia, e.g. the Far East and isolated areas like Kaliningrad, electricity is supplied at regulated rates. Only a minor part of electricity in the price zones is currently traded at free prices. The share of electricity traded at free market prices will increase according to the liberalization schedule, reaching ca 90%, all except households, by 2011. Wholesale electricity market bids are aggregated in a detailed power system model of the Russian power grid, taking into account the physical locations of the facilities. The resulting 7700+ nodal market prices, scattered across the 7 time zones of the Russian market area, capture costs of congestion and load losses in the grid. The price level of electricity seems to be rather low at a glance - about 21 euro and 15 euro per MWh in Europe and Siberia respectively. On the other hand, wholesale market buyers have to pay for capacity availability, on average around 3000 euro/MW monthly. With greater share of electricity traded at free prices there will be an increased need to hedge price risks. For this reason a financial market is planned. There are also plans for support schemes for renewable generation and to limit environmental pollution as well as ancillary services markets. Some areas do not experience a likewise opening of the competition in Russia, for

    Obsessional states show an average point prevalence of 1%-3% and a lifetime prevalence of 2%-2.5%. Most treatment-seeking patients with obsessions continue to experience significant symptoms after 2 years of prospective follow-up. A significant burden of impairment, distress, and comorbidity characterize the course of the illness, leading to an increased need for a better understanding of the nature and management of this condition. This review aims to give a representation of the current pharmacological and psychotherapeutic strategies used in the treatment of obsessive-compulsive disorder. Antidepressants (clomipramine and selective serotonin reuptake inhibitors) are generally the first-line choice used to handle obsessional states, showing good response rates and long-term positive outcomes. About 40% of patients fail to respond to selective serotonin reuptake inhibitors. So far, additional pharmacological treatment strategies have been shown to be effective, ie, administration of high doses of selective serotonin reuptake inhibitors, as well as combinations of different drugs, such as dopamine antagonists, are considered efficacious and well tolerated strategies in terms of symptom remission and side effects. Psychotherapy also plays an important role in the management of obsessive-compulsive disorder, being effective for a wide range of symptoms, and many studies have assessed its long-term efficacy, especially when added to appropriate pharmacotherapy. In this paper, we also give a description of the clinical and psychological features likely to characterize patients refractory to treatment for this illness, with the aim of highlighting the need for greater attention to more patient-oriented management of the disease.

    Full Text Available Affective computing � the ability of a system to recognize, understand and simulate human emotional intelligence � is one of the most dynamic fields of HCI � Human Computer Interaction. These characteristics find their applicability in those areas where it is necessary to extend traditional cognitive communication with emotional features. That is why, Computer Based Speech Therapy Systems (CBST, and especially those involving children with speech disorders, require this qualitative shift. So in this paper we propose an original emotional framework recognition as an extension for our previous developed system � Logomon. A fuzzy model is used in order to interpret the values of specific physiological parameters and to obtain the emotional state of the subject. Moreover, an experiment that indicates the emotion pattern (average fuzzy sets for each therapeutic sequence is also presented. The obtained results encourage us to continue working on automatic emotion recognition and provide important clues regarding the future development of our CBST.

    Systemic activation of cannabinoid receptors often induces biphasic effects on emotional memory and anxiety depending on the levels of emotional arousal associated to the experimental context. The basolateral nucleus of the amygdala (BLA) represents a crucial structure for the ability of endocannabinoid (eCB) signaling to modulate emotional behaviour, and receives dense projections from brainstem arousal system nuclei. We examined whether changes in emotional arousal state would influence the ability of acute eCB manipulations within the BLA to modulate anxiety. Rats were tested in an elevated plus maze (EPM) under low or high arousal conditions. The low emotional arousal group was extensively handled and habituated to the experimental room and tested under red light condition, the high emotional arousal group was not handled or habituated and tested under high light condition. We examined amygdalar eCB anandamide (AEA) and 2-arachidonoylglycerol (2-AG) levels immediately after the EPM and the effects of intra-BLA administration of the AEA hydrolysis inhibitor URB597 or the 2-AG hydrolysis inhibitor KML29 on anxiety behaviour. The modulation of anxiety-like behaviour by eCBs in the BLA was strictly dependent on the environmental-associated emotional arousal. Pharmacologically-induced elevations of AEA or 2-AG in the BLA decreased anxiety under conditions of low emotional arousal. Conversely, when the level of emotional arousal increased, local eCB manipulation was ineffective in the modulation of the emotional arousal-induced anxiety response. These findings suggest that, depending on the emotional arousal state, eCB system is differentially activated to regulate the anxiety response in the amygdala and help to understand the state-dependency of many interventions on anxiety.

    Full Text Available We reveal the psychological mechanisms of impact of the formation level of the teacher’s positive values on the academic performance of students, one of the key components of which are the emotional states of students. We describe a study aimed to test the hypothesis that the positive values and standing behind them “strong” character traits of the teacher determine the emotional states specific of his students during the lesson. The study involved 241 teachers of school subjects and 498 pupils of VI, VIII, X, XI grades of several schools in Krivoy Rog. The study demonstrated that a high level of expression of teacher’s positive values, reflected in his professional qualities, provide the appearance of positive emotional states of students. We also revealed patterns of influence of teacher’s positive personal resource on the intensity of the emotional states experienced by students during lessons.

Emotional processing in BN has not been often studied and has not been considered from a broad perspective. This study aimed at examining the implicit and explicit emotional expression in BN patients, in the acute state and after recovery. Sixty-three female participants were included: 22 BN, 22 recovered BN (R-BN, and 19 healthy controls (HC. The clinical cases were drawn from consecutive admissions and diagnosed according to DSM-IV-TR diagnostic criteria. Self reported (explicit emotional expression was measured with State-Trait Anger Expression Inventory-2, State-Trait Anxiety Inventory, and Symptom Check List-90 items-Revised. Emotional facial expression (implicit was recorded by means of an integrated camera (by detecting Facial Feature Tracking, during a 20 minutes therapeutic video game. In the acute illness explicit emotional expression [anxiety (p<0.001 and anger (p<0.05] was increased. In the recovered group this was decreased to an intermediate level between the acute illness and healthy controls [anxiety (p<0.001 and anger (p<0.05]. In the implicit measurement of emotional expression patients with acute BN expressed more joy (p<0.001 and less anger (p<0.001 than both healthy controls and those in the recovered group. These findings suggest that there are differences in the implicit and explicit emotional processing in BN, which is significantly reduced after recovery, suggesting an improvement in emotional regulation.

  4. The effects of valence-based and discrete emotional states on aesthetic response.

    There is increasing recognition that consumer aesthetics--the responses of consumers to the aesthetic or appearance aspects of products--has become an important area of marketing in recent years. Consumer aesthetic responses to a product are a source of pleasure for the consumer. Previous research into the aesthetic responses to products has often emphasized exterior factors and visual design, but studies have seldom considered the psychological aesthetic experience of consumers, and in particular their emotional state. This study attempts to bridge this gap by examining the link between consumers' emotions and their aesthetic response to a product. Thus, the major goal of this study was to determine how valence-based and discrete emotional states influence choice. In Studies 1 and 2, positive and negative emotions were manipulated to implement two different induction techniques and explore the effect of emotions on participants' choices in two separate experiments. The results of both experiments confirmed the predictions, indicating that aesthetic responses and purchase intention are functions of emotional valence, such that both are stronger for people in a positive emotional state than for those in a negative emotional state. Study 2 also used a neutral affective state to establish the robustness of this observed effect of incidental affect. The results of Study 3 demonstrate that aesthetic response and purchase intention are not only a function of affect valence, but also are affected by the certainty appraisal associated with specific affective states. This research, therefore, contributes to the literature by offering empirical evidence that incidental affect is a determinant of aesthetic response.

Two groups of healthy subjects participated--a group of actor students (N=22) and a group of non-actor students (N=23). EEG power values in the states of emotiogenic texts reading are reproducibly differed with statistical significance from those in the state of reading ofa non-emotiogenic text. States of reading emotionally-positive texts are characterized by increases of EEG power in these bands, while those for emotionally negative texts--by decreases if compared with the state of emotionally neutral reading.

    Automatic emotional processing of faces and facial expressions gain more and more of relevance in terms of social communication. Among a variety of different primes, targets and tasks, whole face images and facial expressions have been used to affectively prime emotional responses. This study investigates whether emotional information provided solely in eye regions that display mental states can also trigger affective priming. Sixteen subjects answered a lexical decision task (LDT) coupled with an affective priming paradigm. Emotion-associated eye regions were extracted from photographs of faces and acted as primes, whereas targets were either words or pseudo-words. Participants had to decide whether the targets were real German words or generated pseudo-words. Primes and targets belonged to the emotional categories "fear," "disgust," "happiness," and "neutral." A general valence effect for positive words was observed: responses in the LDT were faster for target words of the emotional category happiness when compared to other categories. Importantly, pictures of emotional eye regions preceding the target words affected their subsequent classification. While we show a classical priming effect for neutral target words - with shorter RT for congruent compared to incongruent prime-target pairs- , we observed an inverse priming effect for fearful and happy target words - with shorter RT for incongruent compared to congruent prime-target pairs. These inverse priming effects were driven exclusively by specific prime-target pairs. Reduced facial emotional information is sufficient to induce automatic implicit emotional processing. The emotional-associated eye regions were processed with respect to their emotional valence and affected the performance on the LDT.

  8. The effect of weather and its changes on emotional state - individual characteristics that make us vulnerable

    Given the proven effects of weather on the human organism, an attempt to examine its effects on a psychological and emotional level has been made. Emotions affect the bio tone, working ability, and concentration; hence their significance in various domains of economic life such as health care, education, transportation, and tourism. The present pilot study was conducted in Sofia, Bulgaria over a period of eight months, using five psychological methods: Eysenck Personality Questionnaire, State-Trait Anxiety Inventory, Test for Self-assessment of the emotional state, Test for evaluation of moods and Test ''Self-confidence-Activity-Mood''. The Fiodorov-Chubukov's complex-climatic method was used to characterize meteorological conditions in order to include a maximal number of meteorological elements in the analysis. Sixteen weather types are defined depending on the meteorological elements values according to this method. Abrupt weather changes from one day to another, defined by the same method, were also considered. The results obtained by t-test showed that the different categories of weather led to changes in the emotional status, which indicates a character either positive or negative for the organism. The abrupt weather changes, according to expectations, have negative effects on human emotions - but only when a transition to the cloudy weather or weather type, classified as ''unfavorable'', has been realized. The relationship between weather and human emotions is rather complicated since it depends on individual characteristics of people. One of these individual psychological characteristics, marked by the dimension ''neuroticism'', has a strong effect on emotional reactions in different weather conditions. Emotionally stable individuals are more ''resistant'' to the weather influence on their emotions, while those who are emotionally unstable have a stronger dependence on the impacts of weather.

  9. Implications of State Dental Board Disciplinary Actions for Teaching Dental Students About Emotional Intelligence.

    2016-01-01

    The primary emphasis in dental education is on developing students' cognitive intelligence (thinking) and technical intelligence (doing), while emotional intelligence (being) receives less emphasis. The aim of this study was to explore a potential consequence of the paucity of emotional intelligence education by determining the level of emotional intelligence-related (EI-R) infractions in state dental board disciplinary actions and characterizing the types of those infractions. For this study, 1,100 disciplinary action reports from 21 state dental boards were reviewed, and disciplinary infractions were classified as cognitive intelligence-related (CI-R) infractions, technical intelligence-related (TI-R) infractions, and EI-R infractions. EI-R infractions were then subcategorized into emotional intelligence clusters and competencies using the Emotional and Social Competency Inventory (ESCI). The results showed that 56.6% of the infractions were EI-R. When the EI-R infractions were subcategorized, the four competencies most frequently violated involved transparency, teamwork and collaboration, organizational awareness, and accurate self-assessment. Understanding the frequency and nature of EI-R infractions may promote awareness of the need for increased attention to principles of emotional intelligence in dental education and may encourage integration of those principles across dental curricula to help students understand the impact of emotional intelligence on their future well-being and livelihood.

    Pain is a complex phenomenon influenced by context and person-specific factors. Affective dimensions of pain involve both enduring personality traits and fleeting emotional states. We examined how personality traits and emotional states are linked with clinical and evoked pain in a twin sample. 99 female twin pairs were evaluated for clinical and evoked pain using the McGill Pain Questionnaire (MPQ) and dolorimetry, and completed the 120-item International Personality Item Pool (IPIP), the Positive and Negative Affect Scale (PANAS), and ratings of stress and mood. Using a co-twin control design we examined a) the relationship of personality traits and emotional states with clinical and evoked pain and b) whether genetics and common environment (i.e. familial factors) may account for the associations. Neuroticism was associated with the sensory component of the MPQ; this relationship was not confounded by familial factors. None of the emotional state measures was associated with the MPQ. PANAS negative affect was associated with lower evoked pressure pain threshold and tolerance; these associations were confounded by familial factors. There were no associations between IPIP traits and evoked pain. A relationship exists between neuroticism and clinical pain that is not confounded by familial factors. There is no similar relationship between negative emotional states and clinical pain. In contrast, the relationship between negative emotional states and evoked pain is strong while the relationship with enduring personality traits is weak. The relationship between negative emotional states and evoked pain appears to be non-causal and due to familial factors. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available emotions may provide medical information with diagnostic value for healthcare applications and clinical researches. Different emotions can generate specific patterns in physiology via Autonomic Nervous System (ANS. Consequently, we achieve an acceptable accuracy of the emotion classification using extracting relevant features from physiological signals. In this study, an experiment is conducted to elicit four emotional states (happiness, anger, sadness and relax in twenty four healthy subjects. The physiological signals such as ECG, SCL (Skin Conductivity Level, EMG and Respiration signal are recorded simultaneously. After necessary preprocessing for primary signals such as segmentation, filtering, smoothing, removing artifacts and removal of baseline drift, various features in time and frequency domain are extracted. Feature selection method is used to find best relevant features. Afterward, different dimension reduction algorithms and classification methods are used to compare the efficiency of different physiological signals in emotion recognition. The precision of classifications with different features is found to be higher than 70%. The results show that the different physiological signals have different ability to classify four given affective states. Our proposed methods can result in developing a robust emotional states recognition system for healthcare applications.

    Full Text Available In this paper, wavelet packet entropy is proposed for speaker-independent emotion detection from speech. After pre-processing, wavelet packet decomposition using wavelet type db3 at level 4 is calculated and Shannon entropy in its nodes is calculated to be used as feature. In addition, prosodic features such as first four formants, jitter or pitch deviation amplitude, and shimmer or energy variation amplitude besides MFCC features are applied to complete the feature vector. Then, Support Vector Machine (SVM is used to classify the vectors in multi-class (all emotions or two-class (each emotion versus normal state format. 46 different utterances of a single sentence from Berlin Emotional Speech Dataset are selected. These are uttered by 10 speakers in sadness, happiness, fear, boredom, anger, and normal emotional state. Experimental results show that proposed features can improve emotional state detection accuracy in multi-class situation. Furthermore, adding to other features wavelet entropy coefficients increase the accuracy of two-class detection for anger, fear, and happiness.

    Reduction of flux through photorespiration has been viewed as a major way to improve crop carbon fixation and yield since the energy-consuming reactions associated with this pathway were discovered. This view has been supported by the biomasses increases observed in model species that expressed artificial bypass reactions to photorespiration. Here, we present an overview about the major current attempts to reduce photorespiratory losses in crop species and provide suggestions for future research priorities.

  17. Experimental methods to validate measures of emotional state and readiness for duty in critical operations.

    2007-09-01

    A recent report on criticality accidents in nuclear facilities indicates that human error played a major role in a significant number of incidents with serious consequences and that some of these human errors may be related to the emotional state of the individual. A pre-shift test to detect a deleterious emotional state could reduce the occurrence of such errors in critical operations. The effectiveness of pre-shift testing is a challenge because of the need to gather predictive data in a relatively short test period and the potential occurrence of learning effects due to a requirement for frequent testing. This report reviews the different types of reliability and validity methods and testing and statistical analysis procedures to validate measures of emotional state. The ultimate value of a validation study depends upon the percentage of human errors in critical operations that are due to the emotional state of the individual. A review of the literature to identify the most promising predictors of emotional state for this application is highly recommended.

    Full Text Available This study examined the trajectories of emotional states and their within-person synergies with perceived stress and recovery during a 4-month training period preceding the French swimming championships. A Multilevel Growth Curve Analysis approach was used with 16 high level swimmers. Five waves of assessments of emotional states, perceived stress and recovery were completed. Results indicated that emotional states were characterized by distinct trajectories during the training period preceding a major competition. Specifically, significant positive linear effects of time (i.e., linear increase over time and negative quadratic effects of squared time (i.e., inverted U shape over time on anxiety, dejection and anger were observed, whereas the opposite pattern of results was found for happiness and excitement. Moreover, level 2 perceived stress and recovery (i.e., inter-individual predictors were significantly associated with athletes’ unpleasant and pleasant emotional states respectively. At level 1, perceived recovery (i.e., intra-individual predictor was positively associated with happiness and excitement and negatively related to anxiety, dejection and anger. Finally, within-person interactions of general stress and recovery with time and squared time reached significance for excitement, whereas within-person interactions of specific and total stress with time and squared time reached significance for anxiety. Overall, this study provided insights into the central role played by perceived stress and recovery on the emotional states experienced by high level swimmers. Operational strategies were suggested in order to optimize the stress-recovery balance and in turn the athletes’ emotional states during a complete training program.

    Full Text Available The article deals with the psychological interplay between the formation of perceptual skills and personal qualities. The purpose of the study was to determine the characteristics of this relationship during playback of a given sample in different emotional states. It is hypothesized that there is a connection between such personal qualities as a spontaneous aggressiveness, depression, irritability, emotional lability and peculiarities of functioning of sensory-perceptual sphere during playback of a given sample. 55 students of the Smolensk State University took part in the study. The instrumentation consisted of FPI techniques, ITO, R. Plutchik and measurement precision motor skills in different emotional states of the subject. In the experimental part of the work the special research tool specifically created for the given aim was used; it measured errors when playing a sample of the right and left hand of the subject which then was correlated with the results of the survey recipients. Comparative mapping of indicators of pressure on the levers of the meter in different hands clarified their specific contribution to skill formation and its strong correlation with psychological features of a person. The authors made conclusion that the change of emotional state transforms the perception of the sample; in a state of emotional arousal the errors of the right hand when playing the sample increase more rapidly than the errors of the left hand compared with similar work in the state that recipients assessed as normal working conditions; changes in emotional state affect the fidelity of a given sample; examinees do not fully appreciated errors in reproducing the set of standards.

    Osteoporosis is one of the established major consequences of long-duration spaceflights in astronauts seriously undermining their health after their returning on Earth. Indeed, astronauts typically lose more bone mass during one month than postmenopausal women on Earth lose in one year. To date, countermeasures mainly consist in exercise and supplementation while pharmacological treatment as those used in postmenopausal women are not routine. However, it is evident that exercise and supplementation alone are not enough to maintain bone homeostasis. In this paper we describe the current countermeasures for bone loss during long-term spaceflight, review the modern treatment which are successfully employed to prevent osteoporosis on Earth and that could be quickly used also for astronauts and finally focus on the recent cellular and molecular understanding of bone homeostasis which might provide the basis for the development of future targeted therapies.

    Basic aspects of current solar photovoltaics (PVs) are reviewed, starting from the recently developed already-on-the-market first-generation solar cells and ending with promising but not yet commercialized third-generation cells and materials possibly leading to new cell designs. The emphasis is on the physical principles of operation of various solar cells, which are divided into several groups according to our classification scheme. To make the picture complete, some technological and economic aspects of the field are discussed. A separate chapter considers antireflection coatings and light-trapping textures — structures which, while not having appeared yet in the PV review literature, are an integral part of the solar cells.

    Predictions about the future are susceptible to mood-congruent influences of emotional state. However, recent work suggests individuals also differ in the degree to which they incorporate emotion into cognition. This study examined the role of such individual differences in the context of state negative emotion. We examined whether trait tendencies to use negative or positive emotion as information affect individuals' predictions of what will happen in the future (likelihood estimation) and how events will feel (affective forecasting), and whether trait influences depend on emotional state. Participants (N=119) reported on tendencies to use emotion as information ("following feelings"), underwent an emotion induction (negative versus neutral), and made likelihood estimates and affective forecasts for future events. Views of the future were predicted by both emotional state and individual differences in following feelings. Whereas following negative feelings affected most future-oriented cognition across emotional states, following positive feelings specifically buffered individuals' views of the future in the negative emotion condition, and specifically for positive future events, a category of future-event prediction especially important in psychological health. Individual differences may confer predisposition toward optimistic or pessimistic expectations of the future in the context of acute negative emotion, with implications for adaptive and maladaptive functioning.

    Emotional state recognition has become an important topic for human-robot interaction in the past years. By determining emotion expressions, robots can identify important variables of human behavior and use these to communicate in a more human-like fashion and thereby extend the interaction possibilities. Human emotions are multimodal and spontaneous, which makes them hard to be recognized by robots. Each modality has its own restrictions and constraints which, together with the non-structured behavior of spontaneous expressions, create several difficulties for the approaches present in the literature, which are based on several explicit feature extraction techniques and manual modality fusion. Our model uses a hierarchical feature representation to deal with spontaneous emotions, and learns how to integrate multiple modalities for non-verbal emotion recognition, making it suitable to be used in an HRI scenario. Our experiments show that a significant improvement of recognition accuracy is achieved when we use hierarchical features and multimodal information, and our model improves the accuracy of state-of-the-art approaches from 82.5% reported in the literature to 91.3% for a benchmark dataset on spontaneous emotion expressions.

    Full Text Available Developmental differences regarding decision making are often reported in the absence of emotional stimuli and without context, failing to explain why some individuals are more likely to have a greater inclination toward risk. The current study (N = 212; 10–25y examined the influence of emotional context on underlying functional brain connectivity over development and its impact on risk preference. Using functional imaging data in a neutral brain-state we first identify the “brain age” of a given individual then validate it with an independent measure of cortical thickness. We then show, on average, that “brain age” across the group during the teen years has the propensity to look younger in emotional contexts. Further, we show this phenotype (i.e. a younger brain age in emotional contexts relates to a group mean difference in risk perception − a pattern exemplified greatest in young-adults (ages 18–21. The results are suggestive of a specified functional brain phenotype that relates to being at “risk to be risky.”

    Despite preliminary evidence that individuals with borderline personality disorder (BPD) demonstrate deficits in learning from corrective feedback, no studies have examined the influence of emotional state on these learning deficits in BPD. This laboratory study examined the influence of negative emotions on learning among participants with BPD (n = 17), compared with clinical (past-year mood/anxiety disorder; n = 20) and healthy (n = 23) controls. Participants completed a reinforcement learning task before and after a negative emotion induction. The learning task involved presenting pairs of stimuli with probabilistic feedback in the training phase, and subsequently assessing accuracy for choosing previously rewarded stimuli or avoiding previously punished stimuli. ANOVAs and ANCOVAs revealed no significant between-group differences in overall learning accuracy. However, there was an effect of group in the ANCOVA for postemotion induction high-conflict punishment learning accuracy, with the BPD group showing greater decrements in learning accuracy than controls following the negative emotion induction.

    Socio-hydrology was introduced 4 years ago into the scientific lexicon, and elicited several reactions about the meaning and originality of the concept. However, there has also been much activity triggered by the original paper, including further commentaries that clarified the definitions, and several papers that acted on the definitions, and through them further clarified and illustrated the meaning and usefulness of socio-hydrology for understanding coupled human-water systems and underpinning sustainable water management. This presentation discusses how useful these recent studies have been towards the need for socio-hydrology to explain phenomena, such as rise and decline of human population or food production in water scarce basins ('pendulum swing'), the levee effect, small scale farmer suicides, anthropogenic droughts, etc… We also discuss its foundation as a Science, its similarities and dissimilarities with other fields that study human-water interactions, such as hydro-sociology and hydro-economics, its foundation as a Science, current gaps and the challenges that lie ahead.

    The risks involved in surgical treatment and conventional radiotherapy in patients with early lung cancer or lung metastases often make these treatments difficult to justify. However, on the other hand, it is also unacceptable to allow these lesions to evolve freely because, left untreated, these neoplasms will usually lead to the death of the patient. In recent years, alternative local therapies have been developed, such as pulmonary radiofrequency ablation, which has proven to increase survival with a minimal risk of complications. There are common recommendations for these treatments, and although the specific indications for using one technique or another have yet to be established, there are clearly defined situations that will determine the outcome of the treatment. It is important to know these situations, because appropriate patient selection is essential for therapeutic success. This article aims to describe the characteristics and constraints of pulmonary radiofrequency ablation and to outline its role in thoracic oncology in light of the current evidence.

    A variety of studies reported psychological and physiological effects of music. Different types of music have been found to induce different neuroendocrine changes. The aim of the present experiment was to investigate the possible combination of emotional and endocrine changes in response to techno-music and to define personality variables as predictors of respective changes. Sixteen psychosomatically healthy subjects (18- to 19-year-olds, eight males and eight females) were exposed, in random order, to techno-music or to classical music (30 min each). Plasma norepinephrine (NE), epinephrine (EPI), growth hormone (GH), prolactin (PRL), adrenocorticotropic hormone (ACTH) cortisol (CORT), beta-endorphin (beta-EP) concentrations and changes of emotional state were measured in basal conditions and after the experimental trials with two different types of music. Techno-music was associated with a significant increase in heart rate, systolic blood pressure and significant changes in self-rated emotional states. A significant increase was observed in beta-EP, ACTH, NE, GH and CORT after listening to techno-music. Classical music induced an improvement in emotional state, but no significant changes in hormonal concentrations. No differences between male and female subjects' responses to music have been found. Plasma levels of PRL and EPI were unaffected by techno- and classical music. Changes in emotional state and NE, beta-EP and GH responses to techno-music correlated negatively with harm avoidance scores and positively with the novelty-seeking temperament score on the Cloninger scale. Listening to techno-music induces changes in neurotransmitters, peptides and hormonal reactions, related to mental state and emotional involvement: personality traits and temperament may influence the wide inter-individual variability in response to music.

    Culture and gender shape emotion experience and regulation, in part because the value placed on emotions and the manner of their expression is thought to vary across these groups. This study tested the hypothesis that culture and gender would interact to predict people's emotion responding (emotion intensity and regulatory strategies). Chinese (n=220; 52% female) and American undergraduates (n=241; 62% female) viewed photos intended to elicit negative emotions after receiving instructions to either "just feel" any emotions that arose (Just Feel), or to "do something" so that they would not experience any emotion while viewing the photos (Regulate). All participants then rated the intensity of their experienced emotions and described any emotion-regulation strategies that they used while viewing the photos. Consistent with predictions, culture and gender interacted with experimental condition to predict intensity: Chinese men reported relatively low levels of emotion, whereas American women reported relatively high levels of emotion. Disengagement strategies (especially distancing) were related to lower emotional intensity and were reported most often by Chinese men. Taken together, findings suggest that emotion-regulation strategies may contribute to differences in emotional experience across Western and East Asian cultures.

    The last two decades have seen a strong rise in empirical research in the mechanisms of emotion dysregulation in borderline personality disorder. Major findings comprise structural as well as functional alterations of brain regions involved in emotion processing, such as amygdala, insula, and prefrontal regions. In addition, more specific mechanisms of disturbed emotion regulation, e.g. related to pain and dissociation, have been identified. Most recently, social interaction problems and their underlying neurobiological mechanisms, e.g. disturbed trust or hypersensitivity to social rejection, have become a major focus of BPD research. This article covers the current state of knowledge and related relevant research goals. The first part presents a review of the literature. The second part delineates important open questions to be addressed in future studies. The third part describes the research agenda for a large German center grant focusing on mechanisms of emotion dysregulation in BPD.

    Medical malpractice can present an unwelcome professional, emotional, and economic burden to the practicing urologist. To date, there is a paucity of data specific to urologic malpractice in the literature. We performed a comprehensive literature search to identify and evaluate recent studies related to urologic malpractice. We also analyzed 6249 closed urologic claims from the largest available specialty-specific data set gathered by Physician Insurers Association of America from 1985 to 2012. The resulting comprehensive review seeks to raise awareness of current trends in the malpractice environment specific to urologic surgery while also helping urologists identify opportunities for risk management and improved patient care.

    Virtual reality is rapidly evolving into a pragmatically usable technology for mental health (MH) applications. As the underlying enabling technologies continue to evolve and allow us to design more useful and usable structural virtual environments (VEs), the next important challenge will involve populating these environments with virtual representations of humans (avatars). This will be vital to create mental health VEs that leverage the use of avatars for applications that require human-human interaction and communication. As Alessi et al.1 pointed out at the 8th Annual Medicine Meets Virtual Reality Conference (MMVR8), virtual humans have mainly appeared in MH applications to "serve the role of props, rather than humans." More believable avatars inhabiting VEs would open up possibilities for MH applications that address social interaction, communication, instruction, assessment, and rehabilitation issues. They could also serve to enhance realism that might in turn promote the experience of presence in VR. Additionally, it will soon be possible to use computer-generated avatars that serve to provide believable dynamic facial and bodily representations of individuals communicating from a distance in real time. This could support the delivery, in shared virtual environments, of more natural human interaction styles, similar to what is used in real life between people. These techniques could enhance communication and interaction by leveraging our natural sensing and perceiving capabilities and offer the potential to model human-computer-human interaction after human-human interaction. To enhance the authenticity of virtual human representations, advances in the rendering of facial and gestural behaviors that support implicit communication will be needed. In this regard, the current paper presents data from a study that compared human raters' judgments of emotional expression between actual video clips of facial expressions and identical expressions rendered on a

    Full Text Available The paper studied the relationship between emotional experience in childhood and the quality of the existing partnerships. With a questionnaire, specifically designed by I. Tretjakova, 221 respondents aged 20–40 years were interviewed. The study leads to the conclusion that a positive emotional experience in childhood helps to develop emotionally healthy environment in marriage (including unregistered or civil partnership, and creates the desire to have children, and vice versa, emotionally negative experience in childhood disturbs the creation of an emotionally favourable environment for marriage and causes conflicts in relationships, provokes desire to divorce, but it cannot be stated that more interpersonal problems are the cause of lower birth rates than there are at fewer marital problems. The study confirms that a stable marriage can be an important factor contributing to the woman's desire to have children Thus it can be assumed that development of emotion regulation skills could be a contributing factor in order to form successful partnerships and promote birth of more children in the family context.

    Emotional distress is common in Colombian armed conflict victims. Multiple-victimisation is associated with an increase in emotional distress than victimisation due a single event. However, the association between poly-victimisation and emotional distress among victims of the armed conflict in Colombia has not been documented. To study the association between multiple-victimisation and emotional distress in victims of armed conflict in the State of Magdalena, Colombia. A cross-sectional study was designed, with a secondary analysis of registration of the Psychosocial Care Program and Victim Integral Health (PAPSIVI) in the State of Magdalena, from 2013 to 2014. The profile formula grouped demographic variables, victimising events, and a set of symptoms of emotional distress (perceived discrimination, depressive and anxiety-stress). Odds ratio (OR, 95%CI) were established as measures of association. A total of 943 people were included, with 67.4% women, and ages between18 and 94 years (mean 47.9±14.2). A total of 109 (11.7%) suffered from multiple victimisation. Multiple victimisation events were associated with more emotional distress, depressive symptoms (OR=1.5; 95%CI, 1.3-1.8), perceived stigma (OR=1.3; 95%CI, 1.1-1.5), and anxiety-stress (OR=1.2; 95%CI 1.0-1.4) than a single event. There is more emotional distress in multiple victimisations than in a single victimisation event during armed conflict in this region of Colombia. Further studies are required on this topic.

    2015-01-01

    Integrating research efforts using a cross-domain approach could redefine traditional constructs used in behavioral and clinical neuroscience by demonstrating that behavior and mental processes arise not from functional isolation but from integration. Our research group has been examining the interface between cognitive and emotional processes by studying inhibitory gating. Inhibitory gating can be measured via changes in behavior or neural signal processing. Sensorimotor gating of the startle response is a well-used measure. To study how emotion and cognition interact during startle modulation in the animal model, we examined ultrasonic vocalization (USV) emissions during acoustic startle and prepulse inhibition. We found high rates of USV emission during the sensorimotor gating paradigm and revealed links between prepulse inhibition (PPI) and USV emission that could reflect emotional and cognitive influences. Measuring inhibitory gating as P50 event-related potential suppression has also revealed possible connections between emotional states and cognitive processes. We have examined the single unit responses during the traditional gating paradigm and found that acute and chronic stress can alter gating of neural signals in regions such as amygdala, striatum and medial prefrontal cortex. Our findings point to the need for more cross-domain research on how shifting states of emotion can impact basic mechanisms of information processing. Results could inform clinical work with the development of tools that depend upon cross-domain communication, and enable a better understanding and evaluation of psychological impairment.

    We describe the creation of a film library designed for researchers interested in positive (amusing), negative (repulsive), mixed (amusing and repulsive) and neutral emotional states. Three hundred 20- to 33-second film clips videotaped by amateurs were selected from video-hosting websites and screened in laboratory studies by 75 female participants on self-reported amusement and repulsion (Experiments 1 and 2). On the basis of pre-defined cut-off values, 51 positive, 39 negative, 59 mixed and 50 neutral film clips were selected. These film clips were then presented to 411 male and female participants in a large online study to identify film clips that reliably induced the target emotions (Experiment 3). Depending on the goal of the study, researchers may choose positive, negative, mixed or neutral emotional film clips on the basis of Experiments 1 and 2 or Experiment 3 ratings.

  8. Balancing Automatic-Controlled Behaviors and Emotional-Salience States: A Dynamic Executive Functioning Hypothesis

    Recently, there has been growing interest in understanding how executive functions are conceptualized in psychopathology. Since several models have been proposed, the major issue lies within the definition of executive functioning itself. Theoretical discussions have emerged, narrowing the boundaries between “hot” and “cold” executive functions or between self-regulation and cognitive control. Nevertheless, the definition of executive functions is far from a consensual proposition and it has been suggested that these models might be outdated. Current efforts indicate that human behavior and cognition are by-products of many brain systems operating and interacting at different levels, and therefore, it is very simplistic to assume a dualistic perspective of information processing. Based upon an adaptive perspective, we discuss how executive functions could emerge from the ability to solve immediate problems and to generalize successful strategies, as well as from the ability to synthesize and to classify environmental information in order to predict context and future. We present an executive functioning perspective that emerges from the dynamic balance between automatic-controlled behaviors and an emotional-salience state. According to our perspective, the adaptive role of executive functioning is to automatize efficient solutions simultaneously with cognitive demand, enabling individuals to engage such processes with increasingly complex problems. Understanding executive functioning as a mediator of stress and cognitive engagement not only fosters discussions concerning individual differences, but also offers an important paradigm to understand executive functioning as a continuum process rather than a categorical and multicomponent structure.

  9. From Specificity to Sensitivity: Affective states modulate visual working memory for emotional expressive faces

    Full Text Available Previous findings suggest that visual working memory preferentially remembers angry looking faces. However, the meaning of facial actions is construed in relation to context. To date, there are no studies investigating the role of perceiver-based context when processing emotional cues in visual working memory. To explore the influence of affective context on visual working memory for faces, we conducted two experiments using both a visual working memory task for emotionally expressive faces and a mood induction procedure. Affective context was manipulated by unpleasant (Experiment 1 and pleasant (Experiment 2 IAPS pictures in order to induce an affect high in motivational intensity (defensive or appetitive, respectively compared to a low arousal control condition. Results indicated specifically increased sensitivity of visual working memory for angry looking faces in the neutral condition. Enhanced visual working memory for angry faces was prevented by inducing affects of high motivational intensity. In both experiments, affective states led to a switch from specific enhancement of angry expressions in visual working memory to an equally sensitive representation of all emotional expressions. Our findings demonstrate that emotional expressions are of different behavioral relevance for the receiver depending on the affective context, supporting a functional organization of visual working memory along with flexible resource allocation. In visual working memory, stimulus processing adjusts to situational requirements and transitions from a specifically prioritizing default mode in predictable environments to a sensitive, hypervigilant mode in exposure to emotional events.

    Formation peculiarities of the stable and unstable states of high-T{sub c} superconductors are discussed. To understand the basic physical trends, which are characteristic for the current penetration mechanism in high temperature superconductors, the operating states of Bi2212 slab without stabilizing matrix placed in DC external magnetic fields at low coolant temperature are theoretically investigated. It is proved that the temperature of a high-T{sub c} superconductor is not equals to the coolant temperature before instability onset. Therefore, the voltage-current characteristic of a high-T{sub c} superconductor has only a positive slope during continuous current charging. As a result, it does not allow one to find the boundary between stable and unstable thermo - current states. This peculiarity has to be considered during experiments at which the critical current of high-T{sub c} superconductors is defined.

  12. Here, There and Everywhere: Emotion and Mental State Talk in Different Social Contexts Predicts Empathic Helping in Toddlers

    2014-04-01

    Full Text Available A growing body of literature suggests that parents socialize early-emerging prosocial behavior across varied contexts and in subtle yet powerful ways. We focus on discourse about emotions and mental states as one potential socialization mechanism given its conceptual relevance to prosocial behavior and its known positive relations with emotion understanding and social-cognitive development, as well as parents’ frequent use of such discourse beginning in infancy. Specifically, we ask how parents’ emotion and mental state talk with their toddlers relates to toddlers’ helping and how these associations vary by context. Children aged 18- to 30-months (n=38 interacted with a parent during book reading and joint play with toys, two everyday contexts that afford parental discussion of emotions and mental states. Children also participated in instrumental and empathic helping tasks. Results revealed that although parents discuss mental states with their children in both contexts, the nature of their talk differs: during book reading parents labeled emotions and mental states significantly more often than during joint play, especially simple affect words (e.g. happy, sad and explanations or elaborations of emotions; whereas they used more desire talk and mental state words (e.g. think, know in joint play. Parents’ emotion and mental state discourse related to children’s empathic, emotion-based helping behavior; however, it did not relate to instrumental, action-based helping. Moreover, relations between parent talk and empathic helping varied by context: children who helped more quickly had parents who labeled emotion and mental states more often during joint play and who elicited this talk more often during book reading. As emotion and mental state talk both varies between contexts and exhibits context-specific associations with empathic prosocial behavior early in development, we conclude that such discourse may be a key form of socialization

    to investigate peculiarities of psycho-emotional reactions in patients with central serous chorioretinopathy (CSCR). The study involved 35 patients with CSCR (mean age of 47.7±8.5 years) and 26 volunteers without visual impairment (mean age of 35.8±4.5 years). Their psycho-emotional state was studied using the SCL-90-R questionnaire (the severity of psychopathological symptomatology), TOBOL method (the type of attitude to the disease), Ways of Coping Questionnaire (WCQ) (strategies for controlling behavior), Spielberger-Hanin method (the level of anxiety), and the VFQ-25 questionnaire (quality of life). The psycho-emotional state of CSCR patients is characterized by elevated levels of depressive and paranoiac symptoms, obsessions, compulsions, and anxiety. Such patients tend to show supernatural, sthenic desire to maintain their professional status. They tend to try to resolve the conflict by denying the problem, imagining things and distracting oneself. They also show reactive and personal anxiety. In this study, their quality of life was significantly lower than that in healthy volunteers, vision-related criteria particularly concerned. Patients with CSCR demonstrate certain psycho-emotional features that can aggravate their general medical condition as well as the ophthalmic status.

    Arguments that abortion causes women emotional harm are used to regulate abortion, particularly later procedures, in the United States. However, existing research is inconclusive. We examined women's emotions and reports of whether the abortion decision was the right one for them over the three years after having an induced abortion. We recruited a cohort of women seeking abortions between 2008-2010 at 30 facilities across the United States, selected based on having the latest gestational age limit within 150 miles. Two groups of women (n=667) were followed prospectively for three years: women having first-trimester procedures and women terminating pregnancies within two weeks under facilities' gestational age limits at the same facilities. Participants completed semiannual phone surveys to assess whether they felt that having the abortion was the right decision for them; negative emotions (regret, anger, guilt, sadness) about the abortion; and positive emotions (relief, happiness). Multivariable mixed-effects models were used to examine changes in each outcome over time, to compare the two groups, and to identify associated factors. The predicted probability of reporting that abortion was the right decision was over 99% at all time points over three years. Women with more planned pregnancies and who had more difficulty deciding to terminate the pregnancy had lower odds of reporting the abortion was the right decision (aOR=0.71 [0.60, 0.85] and 0.46 [0.36, 0.64], respectively). Both negative and positive emotions declined over time, with no differences between women having procedures near gestational age limits versus first-trimester abortions. Higher perceived community abortion stigma and lower social support were associated with more negative emotions (b=0.45 [0.31, 0.58] and b=-0.61 [-0.93, -0.29], respectively). Women experienced decreasing emotional intensity over time, and the overwhelming majority of women felt that termination was the right decision for

    Critical curves "critical current-external magnetic field" of long Josephson junctions with inhomogeneity and variable width are studied. We demonstrate the existence of regions of magnetic field where some fluxon states are stable only if the external current through the junction is different from zero. Position and size of such regions depend on the length of the junction, its geometry, parameters of inhomogeneity and form of the junction. The noncentral (left and right) pure fluxon states appear in the inhomogeneous Josephson junction with the increase in the junction length. We demonstrate new bifurcation points with change in width of the inhomogeneity and amplitude of the Josephson current through the inhomogeneity.

  17. Mapping current fluctuations of stochastic pumps to nonequilibrium steady states

    We show that current fluctuations in a stochastic pump can be robustly mapped to fluctuations in a corresponding time-independent nonequilibrium steady state. We thus refine a recently proposed mapping so that it ensures equivalence of not only the averages, but also optimal representation of fluctuations in currents and density. Our mapping leads to a natural decomposition of the entropy production in stochastic pumps similar to the "housekeeping" heat. As a consequence of the decomposition of entropy production, the current fluctuations in weakly perturbed stochastic pumps are shown to satisfy a universal bound determined by the steady state entropy production.

    Conditions for current instabilities that arise in high-temperature superconducting composites with essentially nonlinear dependences of the critical current densities and resistivity on the temperature and magnetic induction have been studied. The analysis has been conducted in terms of zero-dimensional models, which has made it possible to formulate general physical mechanisms behind the formation of currents states in superconducting composites according to the external magnetic field induction, cooling conditions, and the properties of the superconductor and cladding. The possible existence of current and temperature stable steps, as well as stable steps of the electric field strength, in the absence of the superconducting-normal transition, has been demonstrated. Reasons for instabilities under multistable current states have been discussed.

    Charging and discharging currents have been measured in a diglycidyl ether of bisphenol-A epoxy resin with and without silica fillers, below and above its glass transition temperature T{sub g} = 65 deg. C. Both transient and steady-state current densities have been analysed. The average applied fields ranged from 3 to 35 kV mm{sup -1} with a sample thickness of 0.5 mm. Above T{sub g}, transient currents suggested a phenomenon of charge injection forming trapped space charges even at low fields. Steady-state currents confirmed that the behaviour was not Ohmic and suggested Schottky-type injection. Below T{sub g}, the current is not controlled by the metal-dielectric interface but by the conduction in the volume: the current is Ohmic at low fields and both transient and steady-state currents suggest a phenomenon of space-charge limited currents at high fields. The field threshold is similar in the filler-free and the filled resin. Values in the range 12-17 kV mm{sup -1} have been measured.

    Full Text Available Phraseology is a treasury of language. It is the fruit, which was born in the result of a long process of the practical use of the language. Phraseologisms give the speech power, persuasiveness, brilliance and imagery. They enliven the language and make it more emotional. In this article, we focus on the negative psycho-emotional state of a person. The negative psycho-emotional state of a person is emotion and feelings that are formed in the result of the negative mood of a person and related to the dissatisfaction with vital needs. The authors of the article identified 5 phraseological subgroups that characterize the negative psycho-emotional state of a person: (1 anger (irritation, rage; (2 disgust, hatred; (3 terror (fear, fright, horror; (4 anxiety, agitation; (5 sadness, melancholy.

    This study combined conceptual frameworks from health information seeking, appraisal theory of emotions, and social determinants of health literatures to examine how emotional states and education predict online health information seeking. Nationally representative data from the Health Information National Trends Survey (HINTS 4, Cycle 3) were used to test the roles of education, anxiety, anger, sadness, hope, happiness, and an education by anxiety interaction in predicting online health information seeking. Results suggest that women, tablet owners, smartphone owners, the college educated, those who are sad some or all of the time, and those who are anxious most of the time were significantly more likely to seek online health information. Conversely, being angry all of the time decreased the likelihood of seeking. Furthermore, two significant interactions emerged between anxiety and education levels. Discrete psychological states and demographic factors (gender and education) individually and jointly impact information seeking tendencies.

    Finding valid indicators of emotional states is one of the biggest challenges in animal welfare science. Here, we investigated in horses whether variation in the expression of eye wrinkles caused by contraction of the inner eyebrow raiser reflects emotional valence. By confronting horses with positive and negative conditions, we aimed to induce positive and negative emotional states, hypothesising that positive emotions would reduce whereas negative emotions would increase eye wrinkle expression. Sixteen horses were individually exposed in a balanced order to two positive (grooming, food anticipation) and two negative conditions (food competition, waving a plastic bag). Each condition lasted for 60 seconds and was preceded by a 60 second control phase. Throughout both phases, pictures of the eyes were taken, and for each horse four pictures per condition and phase were randomly selected. Pictures were scored in random order and by two experimenters blind to condition and phase for six outcome measures: qualitative impression, eyelid shape, markedness of the wrinkles, presence of eye white, number of wrinkles, and the angle between the line through the eyeball and the highest wrinkle. The angle decreased during grooming and increased during food competition compared to control phases, whereas the two phases did not differ during food anticipation and the plastic bag condition. No effects on the other outcome measures were detected. Taken together, we have defined a set of measures to assess eye wrinkle expression reliably, of which one measure was affected by the conditions the horses were exposed to. Variation in eye wrinkle expression might provide valuable information on horse welfare but further validation of specific measures across different conditions is needed.

    Full Text Available Speech Emotion Recognition is a recent research topic in the Human Computer Interaction (HCI field. The need has risen for a more natural communication interface between humans and computer, as computers have become an integral part of our lives. A lot of work currently going on to improve the interaction between humans and computers. To achieve this goal, a computer would have to be able to distinguish its present situation and respond differently depending on that observation. Part of this process involves understanding a user‟s emotional state. To make the human computer interaction more natural, the objective is that computer should be able to recognize emotional states in the same as human does. The efficiency of emotion recognition system depends on type of features extracted and classifier used for detection of emotions. The proposed system aims at identification of basic emotional states such as anger, joy, neutral and sadness from human speech. While classifying different emotions, features like MFCC (Mel Frequency Cepstral Coefficient and Energy is used. In this paper, Standard Emotional Database i.e. English Database is used which gives the satisfactory detection of emotions than recorded samples of emotions. This methodology describes and compares the performances of Learning Vector Quantization Neural Network (LVQ NN, Multiclass Support Vector Machine (SVM and their combination for emotion recognition.

    Previous cross-cultural comparisons of correlations between positive and negative emotions found that East Asians are more likely than Americans to feel dialectical emotions. However, not much is known about the co-occurrence of positive and negative emotions in a given situation. When asked to describe situations in which they felt mixed emotions, Japanese and American respondents listed mostly similar situations. By presenting these situations to another group of respondents, we found that Japanese reported more mixed emotions than Americans in the predominantly pleasant situations, whereas there were no cultural differences in mixed emotions in the predominantly unpleasant situations or the mixed situations. The appraisal of self-agency mediated cultural differences in mixed emotions in the predominantly pleasant situations. Study 2 replicated the findings by asking participants to recall how they felt in their past pleasant, unpleasant, and mixed situations. The findings suggest that both Americans and Japanese feel mixed emotions, but the kinds of situation in which they typically do so depends on culture.

Breach of symmetry in mean arterial pressure and the amplitude - frequency response accompaniment reflex, determine the validity of staying in extreme conditions. Introduction of the measure in using semantic spaces allows by selective data to establish the overall structure of the studied process.

  6. On the relationship between emotional state and abnormal unfairness sensitivity in alcohol dependence

    Full Text Available Recent empirical findings suggest that alcohol dependence is characterized by heightened sensitivity to unfairness during social transactions. The present study went a step further and aimed to ascertain whether this abnormal level of sensitivity to unfairness is underlined by an increased emotional reactivity. Twenty-six recently abstinent alcohol-dependent individuals (AD and 32 controls performed an Ultimatum Game (UG, in which participants had to respond to take-it-or-leave-it offers, ranging from fair to unfair and made by a fictive proposer. Emotional state was recorded during UG offers presentation and was indexed by the amplitude of skin conductance response (SCR. Results showed that AD decided to reject unfair offers more frequently than their controls, confirming previous data. The proportion of rejected unfair UG offers was correlated with SCR, in the AD but not in the control group. This finding suggests that deciding to accept or reject unfair UG offers is influenced by arousal-affective activity in AD, but not in controls. Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent. An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions. Future studies are needed are needed in order to examine whether - emotional and behavioral - reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD.

    Due to changes in gambling accessibility during the last decade gambling has become more widespread in Estonia and the prevalence of pathological gambling has sharply increased. The present study attempts to identify psychological characteristics of Estonian pathological gamblers. It has been shown that a wide range of social, economic, and individual factors (e.g. personality traits and emotional states) predict the likelihood of becoming a pathological gambler. In the present study, pathological gamblers' (N = 33) personality traits, self-esteem, self-reported emotional states and cognitive ability were compared to the respective characteristics in a non-gambling control group (N = 42) matched for age, gender and educational level. It was found that compared to controls, pathological gamblers had higher scores on Neuroticism (especially on its immoderation facet) and lower scores on Conscientiousness (especially on its dutifulness and cautiousness facets) and on self-esteem scale. They reported more negative emotional states during the previous month (especially depression and anxiety). Finally, pathological gamblers had lower general cognitive ability. In a logistic regression model, the likelihood of being a pathological gambler was best predicted by high immoderation score and low cognitive ability.

    College can be stressful for many freshmen as they cope with a variety of stressors. Excess stress can negatively affect both psychological and physical health. Thus, there is a need to find innovative and cost-effective strategies to help identify students experiencing high levels of stress to receive appropriate treatment. Social media use has been rapidly growing, and recent studies have reported that data from these technologies can be used for public health surveillance. Currently, no studies have examined whether Twitter data can be used to monitor stress level and emotional state among college students. The primary objective of our study was to investigate whether students' perceived levels of stress were associated with the sentiment and emotions of their tweets. The secondary objective was to explore whether students' emotional state was associated with the sentiment and emotions of their tweets. We recruited 181 first-year freshman students aged 18-20 years at University of California, Los Angeles. All participants were asked to complete a questionnaire that assessed their demographic characteristics, levels of stress, and emotional state for the last 7 days. All questionnaires were completed within a 48-hour period. All tweets posted by the participants from that week (November 2 to 8, 2015) were mined and manually categorized based on their sentiment (positive, negative, neutral) and emotion (anger, fear, love, happiness) expressed. Ordinal regressions were used to assess whether weekly levels of stress and emotional states were associated with the percentage of positive, neutral, negative, anger, fear, love, or happiness tweets. A total of 121 participants completed the survey and were included in our analysis. A total of 1879 tweets were analyzed. A higher level of weekly stress was significantly associated with a greater percentage of negative sentiment tweets (beta=1.7, SE 0.7; P=.02) and tweets containing emotions of fear (beta=2.4, SE 0.9; P=.01

    The regulation of emotions is an ongoing internal process and often a challenge. Current related neural models concern the intended control of reactions towards external events, mediated by prefrontal cortex regions upon basal emotion processing as in the amygdala. Cognitive strategies to regulate emotions in the context of affective disorders or stress reduction, increasingly applied in clinical practice, are also related to mindfulness techniques. We questioned their effects on neural emotion processing and investigated brain activity during purely internal mental self-referential processes of making current emotions and self-related cognitions aware. Thirty healthy subjects performed a task comprising periods of cognitive self-reflection, of introspection for actual own emotions and feelings, and of a neutral condition, while they were scanned with functional magnetic resonance imaging. Brain activations of twenty-seven subjects during emotion-introspection and self-reflection, and also a conjunction of both, were compared with the neutral condition. The conditions of self-reflection and emotion-introspection showed distinguishable activations in medial and ventrolateral prefrontal areas, in parietal regions and in the amygdala. Notably, amygdala activity decreased during emotion-introspection and increased compared to 'neutral' during self-reflection. The results indicate that already the self-referential mental state of making the actual emotional state aware is capable of attenuating emotional arousal. This extends current theories of emotion regulation and has implications for the application of mindfulness techniques as a component of psychotherapeutic strategies in affective disorders and also for possible everyday emotion regulation.

    Abstract Controversy exists as to whether the lingering effects of concussion on emotional, physical, and cognitive symptoms is because of the effects of brain trauma or purely to emotional factors such as post-traumatic stress disorder or depression. This study examines the independent effects of concussion on persistent symptoms. The Defense Automated Neurobehavioral Assessment, a clinical decision support tool, was used to assess neurobehavioral functioning in 646 United States Marines, all of whom were fit for duty. Marines were assessed for concussion history, post-concussive symptoms, emotional distress, neurocognitive functioning, and deployment history. Results showed that a recent concussion or ever having experienced a concussion was associated with an increase in emotional distress, but not with persistent post-concussive symptoms (PPCS) or neurocognitive functioning. Having had multiple lifetime concussions, however, was associated with greater emotional distress, PPCS, and reduced neurocognitive functioning that needs attention and rapid discrimination, but not for memory-based tasks. These results are independent of deployment history, combat exposure, and symptoms of post-traumatic stress disorder and depression. Results supported earlier findings that a previous concussion is not generally associated with post-concussive symptoms independent of covariates. In contrast with other studies that failed to find a unique contribution for concussion to PPCS, however, evidence of recent and multiple concussion was seen across a range of emotional distress, post-concussive symptoms, and neurocognitive functioning in this study population. Results are discussed in terms of implications for assessing concussion on return from combat. PMID:25003552

    Full Text Available Emotional intelligence (EI is a multi-faceted construct consisting of our ability to perceive, monitor, regulate and use emotions. Despite much attention being paid to the neural substrates of EI, little is known of the spontaneous brain activity associated with EI during resting state. We used resting-state fMRI to investigate the association between the amplitude of low-frequency fluctuations (ALFFs and EI in a large sample of young, healthy adults. We found that EI was significantly associated with ALFFs in key nodes of two networks: the social emotional processing network (the fusiform gyrus, right superior orbital frontal gyrus, left inferior frontal gyrus and left inferior parietal lobule and the cognitive control network (the bilateral pre-SMA, cerebellum and right precuneus. These findings suggest that the neural correlates of EI involve several brain regions in two crucial networks, which reflect the core components of EI: emotion perception and emotional control.

    Full Text Available Telephone banking or brokering, building accesssystems or forensics are some of the areas in which speakerrecognition is continuously developing. Fundamental frequencyrepresents an important speech feature used in theseapplications. In this paper we present a study of the effect ofemotional state of a speaker upon the variation of thefundamental frequency of the speech signal. Human beings arequite frequently overwhelmed by various emotions and most ofthe time one can not really control these emotional states. Forthe purpose of our work we have used the Berlin emotionalspeech database which contains utterances of 10 speakers indifferent emotional situations: happy, angry, fearful, bored andneutral. The mean fundamental frequency and also the standarddeviation for every speaker in all the emotional states werecomputed. The results show a very strong influence of theemotional state upon frequency variation.

    2007-03-01

    We investigate quasi-steady state solutions to transport in quantum systems by finding states which at some time minimize the change in density throughout all space and have a given current density flowing from one part of the system to another [1]. Contrary to classical dynamics, in a quantum mechanical system there are many states with a given energy and particle number which satisfy this minimization criterion. Taking as an example spinless fermions on a one-dimensional lattice, we explicitly show the phase space of a class of quasi-steady states. We also discuss the possibility of coherent and incoherent mixing of these steady state solutions leading to a new type of noise in quantum transport. [1] M. Di Ventra and T.N. Todorov J. Phys. Cond.

    Full Text Available Objective: The aim of this study was to describe the emotional intelligence (EI and examine the corresponding demographic characteristics of front-line Nurse Managers in acute care settings. Methods: This quantitative descriptive study was conducted in eight acute care hospitals in the Midwestern United States. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT was used to measure the EI of 87 front-line Nurse Managers. Demographic characteristics of the participants were captured on a second tool, the Nurse Manager Demographic Characteristics questionnaire. Descriptive and inferential statistics were used for analysis. Results: Significant correlations were found between the perceiving and using branches of the model and total EI score and nurses certified in a specialty. No significant correlations were found between EI and graduate education, age, years in management, percentage of time in management or number of direct reports. Considerations for future research are discussed. Conclusions: Opportunity exists to develop EI in front-line Nurse Managers.

  4. Implicit processing of visual emotions is affected by sound-induced affective states and individual affective traits.

    Directory of Open Access Journals (Sweden)

    Tiziana Quarto

    Full Text Available The ability to recognize emotions contained in facial expressions are affected by both affective traits and states and varies widely between individuals. While affective traits are stable in time, affective states can be regulated more rapidly by environmental stimuli, such as music, that indirectly modulate the brain state. Here, we tested whether a relaxing or irritating sound environment affects implicit processing of facial expressions. Moreover, we investigated whether and how individual traits of anxiety and emotional control interact with this process. 32 healthy subjects performed an implicit emotion processing task (presented to subjects as a gender discrimination task while the sound environment was defined either by a a therapeutic music sequence (MusiCure, b a noise sequence or c silence. Individual changes in mood were sampled before and after the task by a computerized questionnaire. Additionally, emotional control and trait anxiety were assessed in a separate session by paper and pencil questionnaires. Results showed a better mood after the MusiCure condition compared with the other experimental conditions and faster responses to happy faces during MusiCure compared with angry faces during Noise. Moreover, individuals with higher trait anxiety were faster in performing the implicit emotion processing task during MusiCure compared with Silence. These findings suggest that sound-induced affective states are associated with differential responses to angry and happy emotional faces at an implicit stage of processing, and that a relaxing sound environment facilitates the implicit emotional processing in anxious individuals.

    Social interactions, such as an aggressive encounter between two conspecific males or a mating encounter between a male and a female, typically progress from an initial appetitive or motivational phase, to a final consummatory phase. This progression involves both changes in the intensity of the animals' internal state of arousal or motivation and sequential changes in their behavior. How are these internal states, and their escalating intensity, encoded in the brain? Does this escalation drive the progression from the appetitive/motivational to the consummatory phase of a social interaction and, if so, how are appropriate behaviors chosen during this progression? Recent work on social behaviors in flies and mice suggests possible ways in which changes in internal state intensity during a social encounter may be encoded and coupled to appropriate behavioral decisions at appropriate phases of the interaction. These studies may have relevance to understanding how emotion states influence cognitive behavioral decisions at higher levels of brain function.

    Current fluctuations in pure lipid membranes have been shown to occur under the influence of transmembrane electric fields (electroporation) as well as a result from structural rearrangements of the lipid bilayer during phase transition (soft perforation). We demonstrate that the ion permeability during lipid phase transition exhibits the same qualitative temperature dependence as the macroscopic heat capacity of a D15PC/DOPC vesicle suspension. Microscopic current fluctuations show distinct characteristics for each individual phase state. While current fluctuations in the fluid phase show spike-like behaviour of short time scales (~ 2ms) with a narrow amplitude distribution, the current fluctuations during lipid phase transition appear in distinct steps with time scales in the order of ~ 20ms. 1 We propose a theoretical explanation for the origin of time scales and permeability based on a linear relationship between lipid membrane susceptibilities and relaxation times in the vicinity of the phase transition.

    In quality-of-life (QL) research, the genetic susceptibility of negative and positive emotions is frequently ignored, taken for granted, or treated as noise. The objectives are to describe: (1) the major findings of studies addressing the heritable and environmental causes of variation in negative and positive emotional states and (2) the major biological pathways of and genetic variants involved in these emotional states. Literature overview. The heritability estimates for anxiety and depression are 30-40%. Related traits as neuroticism and loneliness are also highly heritable. The hypothalamo-pituitary-adrenal axis is the 'final common pathway' for most depressive symptoms. The many findings of investigated genes are promising but not definitive. Heritability estimates of positive emotional states range between 40 and 50%. Life satisfaction and mental health share common genetic factors with optimism and self-esteem. The prefrontal cortex is a candidate brain area for positive emotional states. Biological and genetic research into positive emotional states is scarce. Genetically informative studies may provide insights into a wide variety of complex questions that traditional QL studies cannot deliver. This insight in turn will help us to design more effective supportive programs that could moderate the outcomes of genetically based predispositions.

    Full Text Available Previous studies have found that attentional blink (AB, a failure to report targets temporally close to each other, can be attenuated separately by (1 emotionally significant test stimuli (T2 and (2 the emotional state of the observer. In the present study, we asked whether and how the (1 and (2 interact. Participants were induced with either positive or negative music and asked to complete an AB task which consisted of low-arousal positive, neutral and negative words as T2. We found low arousal negative words significantly reduced AB more than did other words, while no main nor interaction effect for mood was observed. However, on repeating the experiment and replacing low arousal words with high-arousal ones we not only were able to replicate the finding of an advantage of negative words over others, but detected an effect for the mood of the observer: participants who were induced to become happier using music performed better in detecting T2 across lags and word categories than did participants who became sadder. Our findings suggest an interaction of arousal level of emotional target with the induced mood of participants although the underlying mechanisms responsible for this effect need further investigation.

    There is much current child labor law activity, none of it reflecting concern with occupational health hazards. The focus of the legislation is on time for and dedication to education as youth's foremost priority. The only areas of state legislative change that could affect children's health and safety in the workplace are a general movement toward monetarily increasing fines and penalties and some minor inclusions of agricultural restrictions on young workers. Enforcement efforts are in all cases a primary indication of state commitment to child labor law protections, and these efforts are decreasing.

  18. Uncivilizing "Mental Illness": Contextualizing Diverse Mental States and Posthuman Emotional Ecologies within The Icarus Project.

    Fletcher, Erica Hua

    2017-09-11

    This article argues humans should not be defined strictly at their physical boundaries with clear distinctions between anatomical bodies, mental states, and the rest of the world. Rather, diverse mental states, which are often diagnosed as "mental illness," take shape within greater environmental forces and flows, including those that are constructed online. Drawing from a multi-sited ethnography of The Icarus Project, a radical mental health community, the author situates online narratives written by two of its members within posthuman emotional ecologies in which the exchange of ideas online affects mental states in a profound way. These narratives can be seen as a new type of psychiatric resistance based in new technologies, one that "uncivilizes" mental illness by searching for alternative frameworks and metaphors to understand lived experiences with mental distress. This ethnographic perspective differs significantly from traditional bio-psychiatric models and interventions and can offer both patients and mental healthcare providers with an alternative language to frame mental health.

    Psycho-emotional state is one of the factors effecting human health. Its evaluation allows revealing hidden psychological trauma which can be reason of chronic stress, depression or psychosomatic disorders. Modern techniques of objective psycho-emotional state assessment involve a device which detects electrophysiological parameters of human body connected with emotional reaction and psychological condition. The present study covers development and testing of psycho-emotional state assessment device. The developed implement uses three methods of electrophysiological activity evaluation: electrocardiography, electroencephalography and galvanic skin response detection. The device represents hardware-software complex consisting of nanosensors, measuring unit, lead wires and laptop. Filters are excluded from the measuring circuit due to metrological parameters and noise immunity of implemented nanosensors. This solution minimizes signal distortion and allows measuring signals of 0.3 μV and higher in a wide frequency range (0-10000 Hz) with minimal data loss. In addition, results of preliminary medical studies aimed to find correspondence between different psycho-emotional states and electrophysiological parameters are described. Impact of filters on electrophysiological studies was studied. According to the results conventional filters significantly distort EEG channel information. Further research will be directed to the creation of complete base of electrophysiological parameters related to a particular emotion.

    Phylogenetically the most ancient sense, olfaction is characterized by a unique intimacy with the emotion system. However, mechanisms underlying olfaction-emotion interaction remain unclear, especially in an ever-changing environment and dynamic internal milieu. Perturbing the internal state with anxiety induction in human subjects, we interrogated emotion-state-dependent olfactory processing in a functional magnetic resonance imaging (fMRI) study. Following anxiety induction, initially neutral odors become unpleasant and take longer to detect, accompanied by augmented response to these odors in the olfactory (anterior piriform and orbitofrontal) cortices and emotion-relevant pregenual anterior cingulate cortex. In parallel, the olfactory sensory relay adapts with increased anxiety, incorporating amygdala as an integral step via strengthened (afferent or efferent) connections between amygdala and all levels of the olfactory cortical hierarchy. This anxiety-state-dependent neural circuitry thus enables cumulative infusion of limbic affective information throughout the olfactory sensory progression, thereby driving affectively charged olfactory perception. These findings could constitute an olfactory etiology model of emotional disorders, as exaggerated emotion-olfaction interaction in negative mood states turns innocuous odors aversive, fueling anxiety and depression with rising ambient sensory stress.

  1. Max Scheler's theory of the hierarchy of values and emotions and its relevance to current psychopathology.

    2016-06-01

    The philosopher Max Scheler (1874-1928) set out a hierarchical theory of values and emotions in the early twentieth century. This inspired Kurt Schneider to distinguish two sorts of depressive illness, each conforming to a Störung (disorder) in different levels of Scheler's hierarchy. No other psychopathologist, except Stanghellini, gave the matter much attention. I believe that Scheler's theory is a rich source of insight into psychopathology, general and neuropsychiatric. I therefore give an account of Scheler's scheme, review its extant applications (Schneider's, Stanghellini's), and present suggestions as to its continuing potential relevance in a wide range of psychopathological conditions. © The Author(s) 2016.

  2. Emotion Recognition

    Science.gov (United States)

    Neiberg, Daniel; Elenius, Kjell; Burger, Susanne

    Studies of expressive speech have shown that discrete emotions such as anger, fear, joy, and sadness can be accurately communicated, also cross-culturally, and that each emotion is associated with reasonably specific acoustic characteristics [8]. However, most previous research has been conducted on acted emotions. These certainly have something in common with naturally occurring emotions but may also be more intense and prototypical than authentic, everyday expressions [6, 13]. Authentic emotions are, on the other hand, often a combination of different affective states and occur rather infrequently in everyday life.

    The classic account of language is that language processing occurs in isolation from other cognitive systems, like perception, motor action, and emotion. The central theme of this paper is the relationship between a participant's emotional state and language comprehension. Does emotional context affect how we process neutral words? Recent studies showed that processing of word meaning - traditionally conceived as an automatic process - is affected by emotional state. The influence of emotional state on syntactic processing is less clear. One study reported a mood-related P600 modulation, while another study did not observe an effect of mood on syntactic processing. The goals of this study were: First, to clarify whether and if so how mood affects syntactic processing. Second, to shed light on the underlying mechanisms by separating possible effects of mood from those of attention on syntactic processing. Event-related potentials (ERPs) were recorded while participants read syntactically correct or incorrect sentences. Mood (happy vs. sad) was manipulated by presenting film clips. Attention was manipulated by directing attention to syntactic features vs. physical features. The mood induction was effective. Interactions between mood, attention and syntactic correctness were obtained, showing that mood and attention modulated P600. The mood manipulation led to a reduction in P600 for sad as compared to happy mood when attention was directed at syntactic features. The attention manipulation led to a reduction in P600 when attention was directed at physical features compared to syntactic features for happy mood. From this we draw two conclusions: First, emotional state does affect syntactic processing. We propose mood-related differences in the reliance on heuristics as the underlying mechanism. Second, attention can contribute to emotion-related ERP effects in syntactic language processing. Therefore, future studies on the relation between language and emotion will

    The current article is dedicated to some features of the Russian Federation Armed Forces military personnel health monitoring such as legal and informational provision, methodological basis of functioning, historical aspect of formation and development of the social and hygienic monitoring in the Russian Federation Armed Forces. The term "military personnel health monitoring" is defined as an analytical system of constant and long-term observation, analysis, assessment, studying of factors determined the military personnel health, these factors correlations, health risk factors management in order to minimize them. The current state of the military personnel health monitoring allows coming to the conclusion that the military health system does have forces and resources for state policy of establishing the population health monitoring system implementation. The following directions of the militarily personnel health monitoring improvement are proposed: the Russian Federation Armed Forces medical service record and report system reorganization bringing it closer to the civilian one, implementation of the integrated approach to the medical service informatisation, namely, military personnel health status and medical service resources monitoring. The leading means in this direction are development and introduction of a military serviceman individual health status monitoring system on the basis of a serviceman electronic medical record card. Also it is proposed the current Russian Federation Armed Forces social and hygienic monitoring improvement at the expense of informational interaction between the two subsystems on the basis of unified military medical service space.

    Full Text Available Abstract Hyaluronic acid (HA is a natural and linear polymer composed of repeating disaccharide units of β-1, 3-N-acetyl glucosamine and β-1, 4-glucuronic acid with a molecular weight up to 6 million Daltons. With excellent viscoelasticity, high moisture retention capacity, and high biocompatibility, HA finds a wide-range of applications in medicine, cosmetics, and nutraceuticals. Traditionally HA was extracted from rooster combs, and now it is mainly produced via streptococcal fermentation. Recently the production of HA via recombinant systems has received increasing interest due to the avoidance of potential toxins. This work summarizes the research history and current commercial market of HA, and then deeply analyzes the current state of microbial production of HA by Streptococcus zooepidemicus and recombinant systems, and finally discusses the challenges facing microbial HA production and proposes several research outlines to meet the challenges.

    Full Text Available The article analyses the evolution and the current state of radical Islam in China’s Xinjiang Uyghur Autonomous Region. Chinese government considers Islamic radicalism as a serious threat, in particular in the Xinjiang region, which borders on some states in Central Asia as well as Pakistan and Afghanistan. The purpose of this article is to describe and evaluate roots and historical development of significant groups, in particular the East Turkestan Islamic Movement – ETIM. In its next part, the article deals with the contemporary situation as well as the cooperation between Uyghur radicals and other radical Islamic movements, in particular al-Qaeda and Taliban, and their activities. The article concludes that contemporary Uyghur Islamic radicalism cannot be considered as a major security threat, since the activities of these groups have largely shifted to Pakistan and rather have the nature of a propaganda war.

    Cytogenetics and molecular cytogenetics are and will continue to be indispensable tools in cancer diagnostics. Leukemia and lymphoma diagnostics are still emphases of routine (molecular) cytogenetics and corresponding studies of solid tumors gain more and more prominence. Here, first a historical perspective of molecular tumor cytogenetics is provided, which is followed by the basic principles of the fluorescence in situ hybridization (FISH) approach. Finally the current state of molecular cytogenetics in cancer diagnostics is discussed. Nowadays routine diagnostics includes basic FISH approaches rather than multicolor-FISH. The latter together with modern high-throughput methods have their impact on research to identify new tumor-associated genomic regions.

    Prior studies have examined critical expressed emotion (EE-Crit) in mothers in the intergenerational transmission of depression. However, the potential moderating effect of maternal depression diagnostic status in relation to EE-Crit and youth depressive symptoms has yet to be determined. A total of N=121 biological mother/daughter dyads that differed in maternal depression diagnostic status were recruited for the present study: (1) currently depressed mothers (current depression, n=29); (2) formerly depressed mothers (past depression, n=39); and (3) mothers free from any psychiatric history (healthy controls, n=53). Mothers were administered structured clinical interviews and completed self-report measures of EE-Crit and psychopathology, and daughters self-reported depressive symptoms. Results indicated no significant group differences in EE-Crit; however, current maternal depression status moderated EE-Crit such that the magnitude of the relation between EE-Crit and adolescent depressive symptoms was significantly greater in daughters of currently depressed mothers. These findings highlight the importance of considering current maternal depression, rather than a history of maternal depression, in relation to EE-Crit and adolescent depressive symptoms, providing impetus for future investigations.

    Full Text Available The findings of the present study suggest that anxiety, to some extent, influences the learning of focusing, tracking and vergence. Curiosity, on the other hand, did not influence the learning of any of the visual skills under investigation in the present study. Good visual skills are essential components in achieving educational, economic and social success, and independence. A need has been identified to determine whether the visual skills of students can be improved through sports vision exercises, and whether the potential benefits derived from these sports vision exercises could be influenced by emotional states such as anxiety and curiosity. Since little research has been conducted on the relationship between the learning of visual skills and the presence of these two emotional states, one needs to determine the extent to which anxiety and curiosity affect the learning of visual skills. For the purposes of this study, a quantitative research methodology was used. A quasi-experimental approach was employed to collect data on visual skills and the effects of sports vision exercises on these visual skills. The sample consisted of second-year physiology students (n = 204 and included students of genders, various ethnicities, and ages ranging from 18 to 27 years of age. Anxiety and curiosity were measured by using the State-Trait Personality Inventory (STPI, whilst the visual skills of the participants were measured by using a battery of visual skills tests. The results proved that sports vision exercises can improve some visual skills. It should, however, be noted that anxiety levels must be controlled when administering this training. The findings of the present study suggest that anxiety, to some extent, negatively influences the learning of focusing, tracking and vergence. Curiosity on the other hand did not influence the learning of any of the visual skills under investigation in the present study.

    The efficiency of medical care in the United States has become intensely scrutinized with expectations from patients, families, payors, lawmakers, and, currently, the President. The most effective vehicle to bring more efficient care is the employment of evidence-based medicine whenever possible. Evidence-based medicine is dependent on best evidence, and best evidence is generated from prospective trials. To evaluate current state of evidence based practice in pediatric surgery we reviewed the literature for trials conducted in our field the past 10 years. All randomized controlled trials from January 1999 through December 2009 published in the English literature were identified through a literature search using PubMed (www.pubmed.com). We included only those in pediatric general surgery excluding transplant, oncology, and the other nongeneral subspecialties. The search criteria produced 56 manuscripts, of which 51 described appropriate randomization techniques. A definitive trial design with a sample size calculation was utilized in only 19 studies (34%). A statistically significant difference between treatment arms was identified in 29 of the 56 (52%) trials. There were 26 different journals of publication, with the Journal of Pediatric Surgery being most common (20) followed by Pediatric Surgery International (7). The combined total publications from January 1999 through December 2009 for the 26 journals these randomized trials represent 0.04% of all publications. Appendicitis was the most common condition that was studied (n = 10) followed by pyloric stenosis (n = 4). Trials originated in 19 different countries led by the United States (28%), United Kingdom (14%), and Turkey (12%). There was a generally progressive increase in published trials from 1999 to 2009, however, the percentage of prospective articles published in pediatric surgery was similar to a previous review published in 1999. The current state of evidence-based surgery in pediatric surgery has

    Full Text Available Emotions have a very important impact on human’s beliefs, motivations, actions, and physical states. Emotions predicting and its application in intelligent system can improve the interaction between humans and machines. Current research in artificial emotion focuses on how to measure, calculate, or compute it. However, the transfer of emotion is often too complicated to present full emotion states and changes. This paper combines with emotional dimension and theory of variable fuzzy sets to present a predicting artificial emotion model and shows illustrated example of it. This study shows that any raw data from input can be computed with variable fuzzy set. It provides a mathematical method for representing emotion quantitative, gradual qualitative, and mutated qualitative change. This framework improves calculation methods and mechanisms, closer to real emotional changes.

    Full Text Available The study presented here is aimed at analysing the current state of clothing trade in the Balkan states. The dynamics of change over a 15‐year period following economic reforms are revealed. The clothing industries play a significant role and continue to contribute to the economic prosperity of countries with an inexpensive labour force. For most Balkan States clothing’s export plays an important role in promoting economic growth and development – for example, exports of garments Albania was in 2015, 16.81% of its exports, Republic of Macedonia 11.75% of its exports, in Turkey10.51% etc. The main factors which influence the level of competitiveness of clothing products from the Balkans are the gross value added per employee and wages. When the producers of the Balkan countries will create products with higher added value in garment industry the competitiveness of these countries will decrease. Also rising wages in this industry, as a result of trade union pressure or government policy, will lead to decreasing competitiveness of these products on the EU market and implicitly to the decrease of exports of garments from these countries. The main challenges that must face the Balkan States are related to restructuring of economic system, changing trade markets and patterns, declining of domestic demand of most merchandise, reduction of competitive ability, narrow export base, and lower economies of scale. The main opportunities that most of these countries can exploit are related to their geographical position, membership of the EU market, infrastructure in garment sector, and highly skilled workforce.

    Behavioral Activation is a treatment for depression relying on rewards from activities; but it is possible that the effects of punishments should also be considered, as should its generalizability to the healthy population. Effect of rewards and punishments on emotional states and depression were investigated by using the daily diary method. Participants (7 men, 21 women; M age = 19.4 yr.) recorded their daily activities and the intensity of rewards and punishments accompanying each activity for one week. Positive and negative affects of participants were assessed using the Japanese version of the Positive Affect and Negative Affect Schedule. Multiple regression analysis indicated that both rewards and punishments predicted depressive symptoms. Moreover, rewards (but not punishments) predicted positive affect, whereas punishments predicted negative affects (and rewards did not). These preliminary results suggest that the effects of both rewards and punishments given for activities should be considered in models of behavioral activation.

    2003-01-01

    Analytical solutions of Bean's critical state model with critical current density J sub c being anisotropic are obtained for superconducting cylindrical samples of arbitrary cross section in a parallel geometry. We present a method for calculating the flux fronts and magnetization curves. Results are presented for cylinders with elliptical cross section with a specific form of the anisotropy. We find that over a certain range of the anisotropy parameter the flux fronts have shapes similar to those for an isotropic sample. However, in general, the presence of anisotropy significantly modifies the shape of the flux fronts. The field for full flux penetration also depends on the anisotropy parameter. The method is extended to the case of anisotropic J sub c that also depends on the local field B, and magnetization hysteresis curves are presented for typical values of the anisotropy parameter for the case of |J sub c | that decreases exponentially with |B|.

    One of the most common indications for performing magnetic resonance (MR) imaging of the lumbar spine is the symptom complex thought to originate as a result of degenerative disk disease. MR imaging, which has emerged as perhaps the modality of choice for imaging degenerative disk disease, can readily demonstrate disk pathology, degenerative endplate changes, facet and ligamentous hypertrophic changes, and the sequelae of instability. Its role in terms of predicting natural history of low back pain, identifying causality, or offering prognostic information is unclear. As available modalities for imaging the spine have progressed from radiography, myelography, and computed tomography to MR imaging, there have also been advances in spine surgery for degenerative disk disease. These advances are described in a temporal context for historical purposes with a focus on MR imaging's history and current state. (orig.)

    Zandi, Omid; Hamann, Thomas W

    2015-09-21

    This review describes the potential of hematite as a photoanode material for photoelectrochemical (PEC) water splitting. The current understanding of key loss-mechanisms of hematite are introduced and correlated to performance enhancement strategies. The significant voltage loss associated with overcoming the competitive water oxidation and surface state recombination has recently been surmounted through a combination of high temperature annealing and surface modification with water oxidation catalysts. Substantial efforts have been made at nanostructuring electrodes to increase the charge separation efficiency without sacrificing light absorption. Even in optimized nanostructured electrodes, however, charge separation continues to be the primary barrier to achieving efficient water splitting with hematite. Specifically, significant depletion region recombination results in voltage dependant photocurrent which constrains the fill factor. Thus, future directions to enhance the efficiency of hematite electrodes are discussed with an emphasis on circumventing depletion region recombination.

    The efficiency of organic solar cells is limited by several factors including the photocurrent generation process. Copper phthalocyanine thin films with different grain structures are prepared via thermal evaporation onto interdigitated gold electrodes. The samples are analyzed with atomic force microscopy and then exposed to light pulses to explore the time dependence of photogenerated currents in phthalocyanine thin films. The average grain size is obtained from the correlation length of the height-height correlation function and varies from 30-200nm. The dependence of the recombination of photo-excited, dissociated charge pairs on the electric field is compared with the Onsager mechanism and a simple dual trap state model from which relevant time scales are extracted.

    Full Text Available The purpose of this paper is the proposal of a scale for measuring emotional states experienced within a point of sale, for non-English speaking consumers. Since the validity of the measuring instruments may affect the relevance and quality of managerial decisions, the development of a sufficiently reliable measurement that take into account the specificity of a country becomes necessary. Following a literature review that allowed us to highlight existing measuring instruments of emotional states and their disadvantages, we have developed a measurement scale based on two emotional dimensions: pleasure and arousal (stimulation. Following the Churchill Paradigm, the results of our analysis show that the reliability and construct validity of our scale were improved.

    Science.gov (United States)

    Kao, Cheng-Kai; Liebovitz, David M

    2017-05-01

    This paper discusses the current state, barriers, and future directions of consumer-facing applications (apps). There are currently more than 165,000 mobile health apps publicly available in major app stores, the vast majority of which are designed for patients. The top 2 categories are wellness management and disease management apps, whereas other categories include self-diagnosis, medication reminder, and electronic patient portal apps. Apps specific to physical medicine and rehabilitation also are reviewed. These apps have the potential to provide low-cost, around-the-clock access to high-quality, evidence-based health information to end users on a global scale. However, they have not yet lived up to their potential due to multiple barriers, including lack of regulatory oversight, limited evidence-based literature, and concerns of privacy and security. The future directions may consist of improving data integration into the health care system, an interoperable app platform allowing access to electronic health record data, cloud-based personal health record across health care networks, and increasing app prescription by health care providers. For consumer mobile health apps to fully contribute value to health care delivery and chronic disease management, all stakeholders within the ecosystem must collaborate to overcome the significant barriers.

    Murugappan, Murugappan; Murugappan, Subbulakshmi; Zheng, Bong Siao

    2013-07-01

    [Purpose] Intelligent emotion assessment systems have been highly successful in a variety of applications, such as e-learning, psychology, and psycho-physiology. This study aimed to assess five different human emotions (happiness, disgust, fear, sadness, and neutral) using heart rate variability (HRV) signals derived from an electrocardiogram (ECG). [Subjects] Twenty healthy university students (10 males and 10 females) with a mean age of 23 years participated in this experiment. [Methods] All five emotions were induced by audio-visual stimuli (video clips). ECG signals were acquired using 3 electrodes and were preprocessed using a Butterworth 3rd order filter to remove noise and baseline wander. The Pan-Tompkins algorithm was used to derive the HRV signals from ECG. Discrete wavelet transform (DWT) was used to extract statistical features from the HRV signals using four wavelet functions: Daubechies6 (db6), Daubechies7 (db7), Symmlet8 (sym8), and Coiflet5 (coif5). The k-nearest neighbor (KNN) and linear discriminant analysis (LDA) were used to map the statistical features into corresponding emotions. [Results] KNN provided the maximum average emotion classification rate compared to LDA for five emotions (sadness - 50.28%; happiness - 79.03%; fear - 77.78%; disgust - 88.69%; and neutral - 78.34%). [Conclusion] The results of this study indicate that HRV may be a reliable indicator of changes in the emotional state of subjects and provides an approach to the development of a real-time emotion assessment system with a higher reliability than other systems.

    Different variants of separation processes based on steady-state (continuous sample loading) and non-steady state (batch) operating modes of CCC columns have been analyzed and compared. The analysis is carried out on the basis of the modified equilibrium cell model, which takes into account both mechanisms of band broadening - interphase mass transfer and axial mixing. A full theoretical treatment of the intermittent counter-current chromatography with short sample loading time is performed. Analytical expressions are presented allowing the simulation of the intermittent counter-current chromatography separations for various experimental conditions. Chromatographic and extraction separations have been compared and advantages and disadvantages of the two methods have been evaluated. Further technical development of the CCC machines to implement counter-current extraction separations is considered.

    Resilience is defined as a dynamic, multidimensional process encompassing positive adaptation within the context of significant adversity. The complex nature of this construct makes it a difficult topic to study in neuroimaging research; however, in this article, we propose ways to operationalize resilience. The limited amount of structural and functional neuroimaging studies specifically designed to examine resilience have mainly focused on investigating alterations in regions of the brain involved in emotion and stress regulation circuitry. In the future, neuroimaging of resilience is expected to benefit from functional and structural connectivity approaches and the use of novel imaging task paradigms.

  2. Biodiesel production--current state of the art and challenges.

    Vasudevan, Palligarnai T; Briggs, Michael

    2008-05-01

    Biodiesel is a clean-burning fuel produced from grease, vegetable oils, or animal fats. Biodiesel is produced by transesterification of oils with short-chain alcohols or by the esterification of fatty acids. The transesterification reaction consists of transforming triglycerides into fatty acid alkyl esters, in the presence of an alcohol, such as methanol or ethanol, and a catalyst, such as an alkali or acid, with glycerol as a byproduct. Because of diminishing petroleum reserves and the deleterious environmental consequences of exhaust gases from petroleum diesel, biodiesel has attracted attention during the past few years as a renewable and environmentally friendly fuel. Since biodiesel is made entirely from vegetable oil or animal fats, it is renewable and biodegradable. The majority of biodiesel today is produced by alkali-catalyzed transesterification with methanol, which results in a relatively short reaction time. However, the vegetable oil and alcohol must be substantially anhydrous and have a low free fatty acid content, because the presence of water or free fatty acid or both promotes soap formation. In this article, we examine different biodiesel sources (edible and nonedible), virgin oil versus waste oil, algae-based biodiesel that is gaining increasing importance, role of different catalysts including enzyme catalysts, and the current state-of-the-art in biodiesel production.

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    Agile software development methods are quite popular nowadays and are being adopted at an increasing rate in the industry every year. However, these methods are still lacking usability awareness in their development lifecycle, and the integration of usability/User-Centered Design (UCD) into agile methods is not adequately addressed. This paper presents the preliminary results of a recently conducted online survey regarding the current state of the integration of agile methods and usability/UCD. A world wide response of 92 practitioners was received. The results show that the majority of practitioners perceive that the integration of agile methods with usability/UCD has added value to their adopted processes and to their teams; has resulted in the improvement of usability and quality of the product developed; and has increased the satisfaction of the end-users of the product developed. The top most used HCI techniques are low-fidelity prototyping, conceptual designs, observational studies of users, usability expert evaluations, field studies, personas, rapid iterative testing, and laboratory usability testing.

    2015-06-01

    The group of filamentous fungi contains important species used in industrial biotechnology for acid, antibiotics and enzyme production. Their unique lifestyle turns these organisms into a valuable genetic reservoir of new natural products and biomass degrading enzymes that has not been used to full capacity. One of the major bottlenecks in the development of new strains into viable industrial hosts is the alteration of the metabolism towards optimal production. Genome-scale models promise a reduction in the time needed for metabolic engineering by predicting the most potent targets in silico before testing them in vivo. The increasing availability of high quality models and molecular biological tools for manipulating filamentous fungi renders the model-guided engineering of these fungal factories possible with comprehensive metabolic networks. A typical fungal model contains on average 1138 unique metabolic reactions and 1050 ORFs, making them a vast knowledge-base of fungal metabolism. In the present review we focus on the current state as well as potential future applications of genome-scale models in filamentous fungi.

    Scientific attention to cultural considerations in child neuropsychological assessment has not developed parallel to the focus these issues have received in adult and elderly neuropsychological assessment. There are limited data on the presence, magnitude, etiology, and implications of culture-related differences in cognitive test performance among children. This preliminary report reviews the available empirical literature on the current state of multicultural neuropsychological assessment in children. The review identified articles by searching PubMed and PsycINFO databases, and the tables of contents of Developmental Neuropsychology and Child Neuropsychology from 2003-2008. Of the 1,834 abstracts reviewed, ten papers met inclusion criteria for the review. Five studies were completed in America; four of these compared performance between ethnic groups while the fifth examined neighborhood level poverty indicators exclusively within African-American children. Of the five international studies, all established local normative data and/or were exploratory investigations of neuropsychological functions in specific cultural groups, including Taiwanese infants, South African youth, and bilingual British children. Taken together, the results yield important clinical and research data that begin to inform many of the complex and fascinating mechanisms by which ethnic identity and culture impact cognitive development and the neuropsychological assessment of children. A critique of the existing literature and directions for future research are provided.

    The current state of hydrothermal geochemistry studies being carried out at the field are reported. These studies are based on the results of chemical analysis of water samples collected during 1979 and 1980 at the geothermal wells of the area known as Cerro Prieto I, as well as from those located in the Cerro Prieto II and Cerro Prieto III areas, some of which have only recently started flowing. Data are presented on the chemical variations of the main chemical constituents dissolved in the waters, as well as on the Na/K and Na-K-Ca chemical relations and the temperatures calculated from them and from SiO/sub 2/. Fluid recharge into the reservoir and its direction of flow are interpreted from isotherm contour maps of the field prepared from Na/K and Na-K-Ca geothermometry and from concentration contour maps of some of the main chemical constituents. Well M-43 is discussed as an example of a well affected by well completion problems in its production casing. Its behavior is explained on the basis of the chemical characteristics of the produced water. The chemical changes that have taken place in some of the wells during production are explained by correlating the chemistry with the production mechanisms of the well (steam-water production rates).

    Full Text Available Computed tomography is a noninvasive scan technique widely applied in areas such as medicine, industry, and geology. This technique allows the three-dimensional reconstruction of the internal structure of an object which is lighted with an X-rays source. The reconstruction is formed with two-dimensional cross-sectional images of the object. Each cross-sectional is obtained from measurements of physical phenomena, such as attenuation, dispersion, and diffraction of X-rays, as result of their interaction with the object. In general, measurements acquisition is performed with methods based on any of these phenomena and according to various architectures classified in generations. Furthermore, in response to the need to simulate acquisition systems for CT, software dedicated to this task has been developed. The objective of this research is to determine the current state of CT techniques, for this, a review of methods, different architectures used for the acquisition and some of its applications is presented. Additionally, results of simulations are presented. The main contributions of this work are the detailed description of acquisition methods and the presentation of the possible trends of the technique.

    An anonymous questionnaire-based survey was used to determine the current state of and issues involved in undergraduate education in oral implantology at Tokyo Dental College. The participants comprised 139 students who had received lectures on and practical training in oral implantology in 2013. The results indicate that the overall level of student comprehension was high for both lectures and practical training content; the level of difficulty was appropriate for practical training, but the amount of practice time given requires reconsideration. Over 80% of the students gave positive responses in their overall evaluation of lectures and practical training, and the number of students who had an interest in oral implantology after finishing the course and who wanted to be involved in oral implantology as dentists increased. These results indicate that this undergraduate education program is effective in improving understanding of oral implantology. Improvement is required, however, in lecture methodology and practical training content. It is also suggested that the curriculum should be evaluated by students regularly and that the courses be subject to updating as required.

    2016-05-31

    The US healthcare system is rapidly moving toward rewarding value. Recent legislation, such as the Affordable Care Act and the Medicare Access and CHIP Reauthorization Act, solidified the role of value-based payment in Medicare. Many private insurers are following Medicare's lead. Much of the policy attention has been on programs such as accountable care organizations and bundled payments; yet, value-based purchasing (VBP) or pay-for-performance, defined as providers being paid fee-for-service with payment adjustments up or down based on value metrics, remains a core element of value payment in Medicare Access and CHIP Reauthorization Act and will likely remain so for the foreseeable future. This review article summarizes the current state of VBP programs and provides analysis of the strengths, weaknesses, and opportunities for the future. Multiple inpatient and outpatient VBP programs have been implemented and evaluated; the impact of those programs has been marginal. Opportunities to enhance the performance of VBP programs include improving the quality measurement science, strengthening both the size and design of incentives, reducing health disparities, establishing broad outcome measurement, choosing appropriate comparison targets, and determining the optimal role of VBP relative to alternative payment models. VBP programs will play a significant role in healthcare delivery for years to come, and they serve as an opportunity for providers to build the infrastructure needed for value-oriented care.

    Current Ebola virus outbreak in West Africa already reached the total number of 1,323 including 729 deaths by July 31st. the fatality is around 55% in the southeastern area of Guinea, Sierra Leone, Liberia, and Nigeria. The number of patients with Ebola Hemorrhagic Fever (EHF) was continuously increasing even though the any effective therapeutics or vaccines has not been developed yet. The Ebola virus in Guinea showed 98% homology with Zaire Ebola Virus. Study of the pathogenesis of Ebola virus infection and assess of the various candidates of vaccine have been tried for a long time, especially in United States and some European countries. Even though the attenuated live vaccine and DNA vaccine containing Ebola viral genes were tested and showed efficacy in chimpanzees, those candidates still need clinical tests requiring much longer time than the preclinical development to be approved for the practical treatment. It can be expected to eradicate Ebola virus by a safe and efficient vaccine development similar to the case of smallpox virus which was extinguished from the world by the variola vaccine.

    McPherson, Malinda J; Barrett, Frederick S; Lopez-Gonzalez, Monica; Jiradejvong, Patpong; Limb, Charles J

    2016-01-04

    Emotion is a primary motivator for creative behaviors, yet the interaction between the neural systems involved in creativity and those involved in emotion has not been studied. In the current study, we addressed this gap by using fMRI to examine piano improvisation in response to emotional cues. We showed twelve professional jazz pianists photographs of an actress representing a positive, negative or ambiguous emotion. Using a non-ferromagnetic thirty-five key keyboard, the pianists improvised music that they felt represented the emotion expressed in the photographs. Here we show that activity in prefrontal and other brain networks involved in creativity is highly modulated by emotional context. Furthermore, emotional intent directly modulated functional connectivity of limbic and paralimbic areas such as the amygdala and insula. These findings suggest that emotion and creativity are tightly linked, and that the neural mechanisms underlying creativity may depend on emotional state.

Information on children's academic and emotional adjustment was obtained. American (vs. Chinese) parents' involvement was associated less with their control and more with their autonomy support. Despite these different associations, parents' heightened involvement predicted children's enhanced engagement and achievement similarly in the United States and China. However, it predicted enhanced perceptions of competence and positive emotional functioning more strongly in the United States than China.

    We review a current state of a forest type mapping with Landsat data in Siberia. Target algorithm should be based on dynamic vegetation approach to be applicable to the analysis of the forest type distribution for Siberia, aiming at capability of mapping Siberian forest landscapes for applications such as predicting response of forest composition to climate change. We present data for several areas in West Siberian middle taiga, Central Siberia and East Siberia near Yakutsk. Analysis of the field survey, forest inventory data was made to produce forest type classification accounting for several stages for forest succession and variations in habitats and landforms. Supervised classification was applied to the areas were the ground truth and inventory data are available, including several limited area maps and vegetation survey transects. In Laryegan basin in West Siberia the upland forest areas are dominated by mix of Scots pine on sandy soils and Siberian pine with presence of fir and spruce on the others. Abundance of Scots pine decreases to the west due to change in soils. Those types are separable using Landsat spectral data. In the permafrost area around Yakutsk the most widespread succession type is birch to larch. Three stages of the birch to larch succession are detectable from Landsat image. When Landsat data is used in both West and East Siberia, distinction between deciduous broad-leaved species (birch, aspen, and willow) is generally difficult. Similar problem exist for distinguishing between dark coniferous species (Siberian pine, fir and spruce). Image classification can be improved by applying landform type analysis, such as separation into floodplain, terrace, sloping hills. Additional layers of information can be a promising way to complement Landsat data.

    Pharmacogenomics (PGx) is the science that examines how an individual's genetic make-up affects the safety and efficacy of therapeutic drugs. PGx of response to cardiovascular (CV) medications is of the most successfully translated branches of PGx into the clinical workout. However, the clinical implementation of PGx of CV drugs is yet far beyond the growth of our understanding of the role of genetics in drug therapy. A considerable amount of efforts have been devoted by the regulatory agents like the food and drug administration (FDA) as well as the expert-based networks such as the Clinical Pharmacogenetics Implementation Consortium (CPIC) to overcome the existing barriers. This has been done, at least in part, for some of the most widely prescribed CV drugs, including clopidogrel, warfarin and simvastatin for which the PGx knowledge have been satisfactorily robust to provoke the CPIC to issue the guidelines for these drugs and the FDA to update the drugs' labeling, both strongly recommended the use of genotype-guided dosing for these medications, provided that the genetic data are available. For other drugs, however, studies have produced contradictory results and further large and well-designed clinical trials are required to expand and confirm the clinical utility of their PGx data. This review paper presents the current state of knowledge in the field of PGx of CV medications and describes the facilities assisting to the translation of PGx data into the clinical practice. Afterward, the existing body of PGx literature of the most-commonly used CV medications is comprehensively discussed.

    Europe has repeatedly been affected by droughts, resulting in considerable ecological and economic damage and climate change studies indicate a trend towards increasing climate variability most likely resulting in more frequent drought occurrences also in Europe. Against this background, the European Commission's Joint Research Centre (JRC) is developing methods and tools for assessing, monitoring and forecasting droughts in Europe and develops a European Drought Observatory (EDO) to complement and integrate national activities with a European view. At the core of the European Drought Observatory (EDO) is a portal, including a map server, a metadata catalogue, a media-monitor and analysis tools. The map server presents Europe-wide up-to-date information on the occurrence and severity of droughts, which is complemented by more detailed information provided by regional, national and local observatories through OGC compliant web mapping and web coverage services. In addition, time series of historical maps as well as graphs of the temporal evolution of drought indices for individual grid cells and administrative regions in Europe can be retrieved and analysed. Current work is focusing on validating the available products, developing combined indicators, improving the functionalities, extending the linkage to additional national and regional drought information systems and testing options for medium-range probabilistic drought forecasting across Europe. Longer-term goals include the development of long-range drought forecasting products, the analysis of drought hazard and risk, the monitoring of drought impact and the integration of EDO in a global drought information system. The talk will provide an overview on the development and state of EDO, the different products, and the ways to include a wide range of stakeholders (i.e. European, national river basin, and local authorities) in the development of the system as well as an outlook on the future developments.

    Full Text Available Previous research identified two main emotional outcomes of computer error: anxiety and frustration. These emotions have been associated with low levels of performance in using a computer. The present research used innovative methodology for studying the relations between computer error messages, user anxiety and user frustration. We used the Implicit Association Test (IAT to measure automated associations between error messages and these two emotional outcomes. A sample of 80 participants completed two questionnaires and two IAT designs. Results indicated that user error messages are more strongly associated with anxiety, than with frustration. Personal characteristics such as emotional stability and English proficiency were significantly associated with the implicit anxiety measure, but not with the frustration measure. No significant relations were found between two measures of computer experience and the emotional measures. These results indicated that error related anxiety is associated with personal characteristics.

    Full Text Available The article describes the evolution of ideas about the social state as a fair state based on the concept of the social contract. L. von Stein argues that the purpose of the welfare state was not changing the class structure of society and the elimination of the contradictions between the classes, but rather balancing and minimizing conflicts with the help of property transformations allowing a person to change one’s class affiliation. The main condition for the existence of the welfare state is its policies compliance with the interests of citizens, which provides political stability and social security. The central idea of the welfare constitutional state is that the rights of citizens are guaranteed by the state. The functions of the state and its social responsibilities were transforming over time mainly due to the erosion of state, private and corporate responsibility for providing social services. In most cases, the social programs are developed by the state, but they can also be provided by commercial organizations in the “consumer society”, in which all things and services have a material value and benefit. The welfare state is based on the principle of social justice in the distribution of wealth among the population, thus, every democratic state seeks to become a welfare state, which implies a high level of confidence in the government.

    Full Text Available Distributed leadership can enhance the professional learning communities of schools. The present study explored the leadership experience of Jordanian special education teachers, and their perceptions of common constraints to leadership. A mixed method design was used, including a survey (n = 136 and an interview (n = 23. Results indicated that special education teachers had little experience of leadership roles. They regarded the provision of cognitive and emotional support to colleagues as their most important leadership role, and participating in interview committees and selecting new teachers as the least important. There were no significant mean differences between male and female special education teachers in their level of enacted leadership. Level of education and years of experience were found to have a significant effect on the level of teachers’ leadership.

    Exercise is an important strategy for preventing chronic diseases and promoting the health of older adults. The purpose of this research was to evaluate the effects of an outdoor walking exercise program on the cardiorespiratory function, the flexibility, and the emotional state of elderly Korean women. A nonequivalent control group, pretest-posttest design was used to measure the effects of the exercise program. The subjects were 27 females between the ages of 60 to 75 years. The intensity of the walking program was 40-60% of the target heart-rate with a duration of 50-60 min, 3 times per week at an outdoor track for 8 weeks. The effects of the program were assessed by maximal oxygen uptake (VO2max), resting pulse rate, blood pressure Forced Vital Capacity (FVC), Forced Expiratory Volume per 1 second (FEV1) for cardiorespiratory function, the "sit and reach test" for flexibility, and by the Profile of Mood States (POMS) for emotional state. The physical function and the emotional state of the experimental group improved significantly more than that of the control group except FEV1 and the anger factor of POMS. The VO2max and the flexibility of elderly women in the experimental group progressively improved as the duration of the exercise period continued. The results of this study suggest a practical and easy method of exercise to enhance the health of older women.

    In this article, we describe the history and current state of psychosomatic medicine (PSM) in Japan and propose measures that could be considered based on our view of the future prospects of PSM in Japan. The Japanese Society of PSM (JSPM) was established in 1959, and the first Department of Psychosomatic Internal Medicine in Japan was established at Kyushu University In 1963. PSM in Japan has shown a prominent, unique development, with 3,300 members (as of March 2016), comprised of 71.6% of medical doctors including psychosomatic internal medicine (PIM) specialists, general internists, psychiatrists, pediatricians, obstetricians and gynecologists, dentists, dermatologists, and others. Most of the non-physician members include psychology and nursing staff specialists. The Japanese Society of Psychosomatic Internal Medicine (JSPIM), founded in 1996, is another major society with more than 1,200 physicians that is mainly composed of internists. The first joint congress of the five major PSM societies from each field was held in 2009. They included the Japanese Society of Psychosomatic Medicine, Psychosomatic Obstetrics and Gynecology, Psychosomatic Pediatric Medicine, Psychosomatic Dental Medicine, and Psychosomatic Internal Medicine. Several subdivided societies in related medical fields have also been established for cardiovascular, digestive, dermatological, and oriental medicine and for eating disorders, pain, fibromyalgia, stress science, behavioral medicine, and psycho-oncology. JSPM and JSPIM participate in international activities including publishing BioPsychoSocial Medicine (BPSM) and the establishment of a sister society relationship with the Germany College of PSM. PSM in Japan has adopted a variety of professional psychotherapies, including transactional analysis, autogenic therapy, and cognitive behavioral therapy. Mutual interrelationship has been promoted by the Japanese Union of Associations for Psycho-medical Therapy (UPM). Although PSM in Japan is

    Highlights: • Electron cyclotron resonance heating (ECRH) of QUEST. • Particle guiding center orbit calculation. • Orbit-driven current density profile. • Hollow current density. • Equilibrium condition for steady-state operation of QUEST. - Abstract: In the present RF-driven divertor plasma of QUEST, it has been observed that orbit-driven current flows in the open magnetic surfaces outside of the closed magnetic surfaces. To observe this phenomenon and the characteristics of the orbit-driven current, current density profiles have been calculated on two different equilibrium conditions. We calculated current density profiles from particle guiding center orbits both for the fundamental and the second harmonic resonances for the 8.2 GHz electron cyclotron current drive. From this calculation, hollow current density profiles have been obtained with significant characteristics on both conditions. Only positive current distribution has been observed in the open magnetic surfaces outside of the closed magnetic surfaces.

    2014-01-01

    This monograph reports on advances in the measurement and study of autonomic nervous system (ANS) dynamics as a source of reliable and effective markers for mood state recognition and assessment of emotional responses. Its primary impact will be in affective computing and the application of emotion-recognition systems. Applicative studies of biosignals such as: electrocardiograms; electrodermal responses; respiration activity; gaze points; and pupil-size variation are covered in detail, and experimental results explain how to characterize the elicited affective levels and mood states pragmatically and accurately using the information thus extracted from the ANS. Nonlinear signal processing techniques play a crucial role in understanding the ANS physiology underlying superficially noticeable changes and provide important quantifiers of cardiovascular control dynamics. These have prognostic value in both healthy subjects and patients with mood disorders. Moreover, Autonomic Nervous System Dynamics for Mood and ...

    Finding valid indicators of emotional states is one of the biggest challenges in animal welfare science. Here, we investigated in horses whether variation in the expression of eye wrinkles caused by contraction of the inner eyebrow raiser reflects emotional valence. By confronting horses with positive and negative conditions, we aimed to induce positive and negative emotional states, hypothesising that positive emotions would reduce whereas negative emotions would increase eye wrinkle expression. Sixteen horses were individually exposed in a balanced order to two positive (grooming, food anticipation) and two negative conditions (food competition, waving a plastic bag). Each condition lasted for 60 seconds and was preceded by a 60 second control phase. Throughout both phases, pictures of the eyes were taken, and for each horse four pictures per condition and phase were randomly selected. Pictures were scored in random order and by two experimenters blind to condition and phase for six outcome measures: qualitative impression, eyelid shape, markedness of the wrinkles, presence of eye white, number of wrinkles, and the angle between the line through the eyeball and the highest wrinkle. The angle decreased during grooming and increased during food competition compared to control phases, whereas the two phases did not differ during food anticipation and the plastic bag condition. No effects on the other outcome measures were detected. Taken together, we have defined a set of measures to assess eye wrinkle expression reliably, of which one measure was affected by the conditions the horses were exposed to. Variation in eye wrinkle expression might provide valuable information on horse welfare but further validation of specific measures across different conditions is needed. PMID:27732647

  18. Correlations between social-emotional feelings and anterior insula activity are independent from visceral states but influenced by culture

    Directory of Open Access Journals (Sweden)

    Mary Helen eImmordino-Yang

    2014-09-01

    Full Text Available The anterior insula (AI maps visceral states and is active during emotional experiences, a functional confluence that is central to neurobiological accounts of feelings. Yet, it is unclear how AI activity correlates with feelings during social emotions, and whether this correlation may be influenced by culture, as studies correlating real-time AI activity with visceral states and feelings have focused on Western subjects feeling physical pain or basic disgust. Given psychological evidence that social-emotional feelings are cognitively constructed within cultural frames, we asked Chinese and American participants to report their feeling strength to admiration and compassion-inducing narratives during fMRI with simultaneous electrocardiogram recording. Trial-by-trial, cardiac arousal and feeling strength correlated with ventral and dorsal AI activity bilaterally but predicted different variance, suggesting that interoception and social-emotional feeling construction are concurrent but dissociable AI functions. Further, although the variance that correlated with cardiac arousal did not show cultural effects, the variance that correlated with feelings did. Feeling strength was especially associated with ventral AI activity (the autonomic modulatory sector in the Chinese group but with dorsal AI activity (the visceral-somatosensory/cognitive sector in an American group not of Asian descent. This cultural group difference held after controlling for posterior insula activity and was replicated. A bi-cultural East-Asian American group showed intermediate results. The findings help elucidate how the AI supports feelings and suggest that previous reports that dorsal AI activation reflects feeling strength are culture related. More broadly, the results suggest that the brain’s ability to construct conscious experiences of social emotion is less closely tied to visceral processes than neurobiological models predict and at least partly open to cultural

    2007-01-01

    Full Text Available Corticosteroids regulate stress response and influence emotion, learning, and memory via two receptors in the brain, the high‐affinity mineralocorticoid (MR and low‐affinity glucocorticoid receptor (GR. We test the hypothesis that MR- and GR-mediated effects interact in emotion and cognition when a novel situation is encountered that is relevant for a learning process. By adrenalectomy and additional constant corticosterone supplement we obtained four groups of male C57BL/6J mice with differential chronic MR and GR activations. Using a hole board task, we found that mice with continuous predominant MR and moderate GR activations were fast learners that displayed low anxiety and arousal together with high directed explorative behavior. Progressive corticosterone concentrations with predominant action via GR induced strong emotional arousal at the expense of cognitive performance. These findings underline the importance of a balanced MR/GR system for emotional and cognitive functioning that is critical for mental health.

    2014-07-01

    Full Text Available An essential component of youths’ successful development is learning to appropriately respond to emotions, including the ability to recognize, identify, and describe one’s feelings. Such emotional competence is thought to arise through the parent-child relationship. Yet, the mechanisms by which parents transmit emotional competence to their children are difficult to measure because they are often implicit, idiosyncratic, and not easily articulated by parents or children. In the current study, we used a multifaceted approach that went beyond self-report measures and examined whether parental neural sensitivity to emotions predicted their child’s emotional competence. Twenty-two adolescent-parent dyads completed an fMRI scan during which they labeled the emotional expressions of negatively valenced faces. Results indicate that parents who recruited the amygdala, VLPFC, and brain regions involved in mentalizing (i.e., inferring others’ emotional states had adolescent children with greater emotional competence. These results held after controlling for parents’ self-reports of emotional expressivity and adolescents’ self-reports of the warmth and support of their parent relationships. In addition, adolescents recruited neural regions involved in mentalizing during affect labeling, which significantly mediated the associated between parental neural sensitivity and adolescents’ emotional competence, suggesting that youth are modeling or referencing their parents’ emotional profiles, thereby contributing to better emotional competence.

    Grillon, Christian; Quispe-Escudero, David; Mathur, Ambika; Ernst, Monique

    2015-06-01

    Because healthy physical and mental functioning depends on the ability to regulate emotions, it is important to identify moderators of such regulations. Whether mental fatigue, subsequent to the depletion of cognitive resources, impairs explicit emotion regulation to negative stimuli is currently unknown. This study explored this possibility. In a within-subject design over 2 separate sessions, healthy individuals performed easy (control session) or difficult (depletion session) cognitive tasks. Subsequently, they were presented with neutral and negative pictures, with instructions to either maintain or regulate (i.e., reduce) the emotions evoked by the pictures. Emotional reactivity was probed with the startle reflex. The negative pictures evoked a similar aversive state in the control and depletion sessions as measured by startle potentiation. However, subjects were able to down-regulate their aversive state only in the control session, not in the depletion session. These results indicate that mental fatigue following performance of cognitive tasks impairs emotion regulation without affecting emotional reactivity. These findings suggest that mental fatigue needs to be incorporated into models of emotion regulation.

    2016-08-01

    Switching of power circuit breakers is an important technical issue, especially at short circuit, since the fault current cause thermal and dynamic stresses, and the power quality worsens. Recently, the development of distributed renewable electricity induces the short circuit protection problematic because the distributed production of electric energy cause the transport networks to lose their radial character and disturbs the protective relays coordination. The modern technologies for power switching uses static fault current limiters, which offers a viable solution to remove the problems caused by large fault currents in the system. An appropriate design of the current limiting device reduces the thermal and dynamic stress and limits the fault current to a low value. The static switches are based on high power semiconductor devices that offer advantages compared to mechanical switches. Using a fault current limiter that minimizes the effect of distributed generation of electricity in a radial network on the co-ordination of protective relays is a solution to this problem in terms of switching speed and lifespan of power switches.

  13. Tri-State Current Source Inverter With Improved Dynamic Performance

    DEFF Research Database (Denmark)

    Blaabjerg, Frede; Loh, Poh Chiang; Wong, Chow Pang

    2008-01-01

    Traditional dc-ac current source inverter (CSI) has a right-half-plane (RHP) zero in its control-to-output transfer function. This RHP zero causes the inverter output to fall before rising when a step increase in command reference is required (commonly known as non-minimum-phase effect). To achieve...... sequence, the inductive boosting and discharging intervals can be decoupled, allowing the RHP zero to be eliminated with only minor circuit modifications (high level control schemes like predictive and multiloop voltage/current control remain unchanged). The designed inverter can be controlled using...

    Full Text Available Background: Illness representations (based on Leventhal's model are associated with chronic illness outcomes. It has been suggested that targeting these cognitive components improves illness outcomes. Multiple sclerosis is a common disorder between neural and immune systems that creates physical and psychological consequences. There are few pre psychological trails on these patients. The aim of this study was to determine effectiveness of cognitive-behavior therapy on altering illness representations and improving emotional states of the patients.Methods: By using a randomized controlled trial design, among 52 selected patients, 35 volunteers randomly were allocated into intervention and control groups. An extensive interventional cognitive behavior therapy based package was conducted to intervention group in 10 weekly sessions. The control group stayed in waiting list and participated in 5 group meeting sessions. (IPQR and (DASS-42 psychological scales were administered, Leven and T statistical tests were applied for dat analysis.Results: The results showed positive changes in four illness representation components of patients including illness (identity, consequences, coherence and personal control. Associated improvement occurred in depression, anxiety, stress and emotional representations.Conclusion: Mooney and Padeskey's theoretically based cognitive-behavior therapy, is effective on illness representations modification and improving emotional states of the patients. The findings are less similar to Goodman's trial on Systemic Lupus Erythematosus patients and more similar to Petrie's trail on cardiac patients.

  4. LOW ADHERENCE TO TREATMENT AFTER MYOCARDIAL INFARCTION: CAUSES AND WAYS OF ADJUSTMENT CONSIDERING PSYCHO-EMOTIONAL STATE OF PATIENTS

    Full Text Available Aim. To study the reasons of low adherence to treatment in patients after myocardial infarction as well as methods of its correction considering the mental and emotional state of patients. Material and methods. Patients (n=115 after myocardial infarction registered in "Acute Myocardial Infarction Register» were enrolled into the study. The Moriscos-Green scale was used to determine the degree of adherence to treatment, and psycho-emotional state of patients was assessed by the Hospital Anxiety and Depression Scale (HADS. The special questionnaire was used to study the causes of poor adherence. Results. Only 45% of patients after myocardial infarction have a high commitment to the doctor's recommendations. The main reason for low adherence was forgetfulness (42%. Among other reasons were: fear of side effects (16%; lack of therapeutic effect according to patients' opinion (12%; doubts about the doctor's prescriptions (14%; a large number of prescribed drugs (12%; high cost of drugs (4%. The structure of the causes of poor adherence to treatment varied greatly depending on the psycho-emotional status. Adherence to treatment can be improved by specific physician’s actions (48.5% of patients. At the same time 14% of patients did not want to take drugs for a long time under any circumstances. Conclusion. Adherence to treatment of patients after myocardial infarction deserves attention from doctors. The personalized approach considering patient’s opinion, as well as their specific features, is essential for the development of ways to improve adherence.

    In this study, to investigate the influence of incidental emotions on decision making in high-anxious individuals, participants were required to perform a monetary gambling task. Behavioral and electroencephalography responses were recorded to explore the stages of option assessment and outcome evaluation during decision making, respectively. Incidental emotions were elicited by facial expression pictures presented on the background, which included four conditions (control, neutral, fearful, and happy). Results showed smaller feedback-related negativity (FRN) amplitudes in high-anxious participants than low-anxious participants in the control, neutral, and fearful conditions, but not in the happy condition, for small outcomes. The P3 amplitudes were larger in high-anxious participants compared to their counterparts in the fearful and happy conditions, but not in the other conditions. In short, the interaction effects between trait anxiety and facial emotions manifested on the outcome evaluation stage of decision making.

  9. The current state of FPGA technology in the nuclear domain

    Energy Technology Data Exchange (ETDEWEB)

    Ranta, J.

    2012-07-01

    Field programmable gate arrays are a form of programmable electronic device used in various applications including automation systems. In recent years, there has been a growing interest in the use of FPGA-based systems also for safety automation of nuclear power plants. The interest is driven by the need for reliable new alternatives to replace, on one hand, the aging technology currently in use and, on the other hand, microprocessor and software-based systems, which are seen as overly complex from the safety evaluation point of view. This report presents an overview of FPGA technology, including hardware aspects, the application development process, risks and advantages of the technology, and introduces some of the current systems. FPGAs contain an interesting combination of features from software-based and fully hardware-based systems. Application development has a great deal in common with software development, but the final product is a hardware component without the operating system and other platform functions on which software would execute. Currently the number of FPGA-based applications used for safety functions of nuclear power plants is rather limited, but it is growing. So far there is little experience or common solid understanding between different parties on how FPGAs should be evaluated and handled in the licensing process. (orig.)

    2009-09-01

    Full Text Available An analysis of the present state of ornithological knowledge is required for the guidance of researchers in their future investigations. This work provides a survey of literature describing the development of ornithological research in the state. Between 1880 and 2008, many lists were organized, which contributed towards the systematization of the knowledge about Pernambuco’s birds. Out if the 535 species recorded, 49 are found in marine environments or wetlands, 450 occur in the Atlantic Rainforest, and 270 reside in the semi-arid Caatinga. We suggest that studies on the birds of the Caatinga are most important and should be prioritized at present, in addition to effective actions for the conservation of endemic species and of species under risk of extinction.

  14. Invited review: Current state of genetic improvement in dairy sheep.

    Carta, A; Casu, Sara; Salaris, S

    2009-12-01

    Dairy sheep have been farmed traditionally in the Mediterranean basin in southern Europe, central Europe, eastern Europe, and in Near East countries. Currently, dairy sheep farming systems vary from extensive to intensive according to the economic relevance of the production chain and the specific environment and breed. Modern breeding programs were conceived in the 1960s. The most efficient selection scheme for local dairy sheep breeds is based on pyramidal management of the population with the breeders of nucleus flocks at the top, where pedigree and official milk recording, artificial insemination, controlled natural mating, and breeding value estimation are carried out to generate genetic progress. The genetic progress is then transferred to the commercial flocks through artificial insemination or natural-mating rams. Increasing milk yield is still the most profitable breeding objective for several breeds. Almost all milk is used for cheese production and, consequently, milk content traits are very important. Moreover, other traits are gaining interest for selection: machine milking ability and udder morphology, resistance to diseases (mastitis, internal parasites, scrapie), and traits related to the nutritional value of milk (fatty acid composition). Current breeding programs based on the traditional quantitative approach have achieved appreciable genetic gains for milk yield. In many cases, further selection goals such as milk composition, udder morphology, somatic cell count, and scrapie resistance have been implemented. However, the possibility of including other traits of selective interest is limited by high recording costs. Also, the organizational effort needed to apply the traditional quantitative approach limits the diffusion of current selection programs outside the European Mediterranean area. In this context, the application of selection schemes assisted by molecular information, to improve either traditional dairy traits or traits costly to record

    2017-01-31

    Accurate and consistent variant classification is required for Precision Medicine. But clinical variant classification remains in its infancy. While recent guidelines put forth jointly by the American College of Medical Genetics and Genomics (ACMG) and Association of Molecular Pathology (AMP) for the classification of Mendelian variants has advanced the field, the degree of subjectivity allowed by these guidelines can still lead to inconsistent classification across clinical molecular genetic laboratories. In addition, there are currently no such guidelines for somatic cancer variants, only published institutional practices. Additional variant classification guidelines, including disease- or gene-specific criteria, along with inter-laboratory data sharing is critical for accurate and consistent variant interpretation.

    Full Text Available Abstract Background Halitosis represents a common dental condition, although sufferers are often not conscious of it. The aim of this study was to examine behavior in a sample of Italian subjects with reference to self-reported halitosis and emotional state, and specifically the presence of dental anxiety. Methods The study was performed on Italian subjects (N = 1052; range 15-65 years. A self-report questionnaire was used to detect self-reported halitosis and other variables possibly linked to it (sociodemographic data, medical and dental history, oral hygiene, and others, and a dental anxiety scale (DAS divided into two subscales that explore a patient's dental anxiety and dental anxiety concerning dentist-patient relations. Associations between self-reported halitosis and the abovementioned variables were examined using multiple logistic regression analysis. Correlations between the two groups, with self-perceived halitosis and without, were also investigated with dental anxiety and with the importance attributed to one's own mouth and that of others. Results The rate of self-reported halitosis was 19.39%. The factors linked with halitosis were: anxiety regarding dentist patient relations (relational dental anxiety (OR = 1.04, CI = 1.01-1.07, alcohol consumption (OR = 0.47, CI = 0.34-0.66, gum diseases (OR = 0.39, CI = 0.27-0.55, age > 30 years (OR = 1.01, CI = 1.00-1.02, female gender (OR = 0.71, CI = 0.51-0.98, poor oral hygiene (OR = 0.65, CI = 0.43-0.98, general anxiety (OR = 0.66, CI = 0.49-0.90, and urinary system pathologies (OR = 0.46, CI = 0.30-0.70. Other findings emerged concerning average differences between subjects with or without self-perceived halitosis, dental anxiety and the importance attributed to one's own mouth and that of others. Conclusions Halitosis requires professional care not only by dentists, but also psychological support as it is a problem that leads to avoidance behaviors and thereby limits relationships. It

  1. Current state of herbicides in herbicide-resistant crops.

    Science.gov (United States)

    Green, Jerry M

    2014-09-01

    Current herbicide and herbicide trait practices are changing in response to the rapid spread of glyphosate-resistant weeds. Growers urgently needed glyphosate when glyphosate-resistant crops became available because weeds were becoming widely resistant to most commonly used selective herbicides, making weed management too complex and time consuming for large farm operations. Glyphosate made weed management easy and efficient by controlling all emerged weeds at a wide range of application timings. However, the intensive use of glyphosate over wide areas and concomitant decline in the use of other herbicides led eventually to the widespread evolution of weeds resistant to glyphosate. Today, weeds that are resistant to glyphosate and other herbicide types are threatening current crop production practices. Unfortunately, all commercial herbicide modes of action are over 20 years old and have resistant weed problems. The severity of the problem has prompted the renewal of efforts to discover new weed management technologies. One technology will be a new generation of crops with resistance to glyphosate, glufosinate and other existing herbicide modes of action. Other technologies will include new chemical, biological, cultural and mechanical methods for weed management. From the onset of commercialization, growers must now preserve the utility of new technologies by integrating their use with other weed management technologies in diverse and sustainable systems.

  2. Current state of knowledge about nutritional care of pregnant women

    Luciana Barretto

    2014-12-01

    Full Text Available Pregnancy involves a significant anabolic activity that leads to increased nutritional needs relative to the preconception period. This paper aims to review the current understanding of the energy needs of macro and micronutrients during pregnancy as well as guidelines to address common gastrointestinal disorders during pregnancy, the issue of pica and anthropometric assessment to ensure an optimum weight gain. With the exception of iron, most of the nutrients needed by the pregnancy can be provided by a complete and balanced diet. Currently the scientific evidence shows that routine supplementation with iron and folic acid during pregnancy is a practice that prevents iron deficiency anemia, neural tube disorders and preterm births. Intermittent iron supplementation can also be an appropriated intervention. If the diet does not guarantee and adequate support, iodine, vitamin B12 and vitamin D supplements should also be necessaries. The anthropometric assessment by the pattern of weight gain should be present at each prenatal care visit to prevent maternal and fetal complications. In situations where the mother’s weight cannot be assessed, arm muscle circumference is possible to make an overall assessment as it correlates with maternal weight gain alternative. Measurements of biceps, triceps and subscapular skinfolds are another alternative that is useful to evaluate the fatty deposits and their location, in a complementary way to gain weight.

    Even though modern surgical techniques are dominating reconstructive facial procedures, the capability to use facial epitheses for reconstruction is still an important skill for the maxillofacial surgeon. We present an international multicenter analysis to clarify which techniques are used to fixate facial prostheses. We contacted all maxillofacial departments in Germany, Austria, Switzerland and Norway which were registered with the German society for oral and maxillofacial surgery (DGMKG). These centers were asked via electronical mail to provide information on the type of epithesis fixation systems currently in use. The return rate from 58 departments was 43.1% (n = 25). Overall, implant fixation was the preferred fixation system (92%). Plates were the second most common fixation technique (32%). No centers reported the standard use of non-invasive fixation techniques for permanent epithesis fixation. The main retention systems in use were magnets (24/25), other retention systems are used much less often. The current preferred fixation technique for facial epitheses consists of implant-based, magnet-fixated epitheses. For nasal prostheses, a plate-based, magnet-fixated system is often used.

    Full Text Available Early diagnosis of hepatocellular carcinoma (HCC is crucial for optimizing treatment outcome. Ongoing advances are being made in imaging of HCC regarding detection, grading, staging, and also treatment monitoring. This review gives an overview of the current international guidelines for diagnosing HCC and their discrepancies as well as critically summarizes the role of magnetic resonance imaging (MRI and computed tomography (CT techniques for imaging in HCC. The diagnostic performance of MRI with nonspecific and hepatobililiary contrast agents and the role of functional imaging with diffusion-weighted imaging will be discussed. On the other hand, CT as a fast, cheap and easily accessible imaging modality plays a major role in the clinical routine work-up of HCC. Technical advances in CT, such as dual energy CT and volume perfusion CT, are currently being explored for improving detection, characterization and staging of HCC with promising results. Cone beam CT can provide a three-dimensional analysis of the liver with tumor and vessel characterization comparable to cross-sectional imaging so that this technique is gaining an increasing role in the peri-procedural imaging of HCC treated with interventional techniques.

    The use of interactive screen media is widespread and for some users leads to pathological symptoms that are phenomenologically similar to signs of addictive disorders. Addictive use of computer games and other Internet applications, such as social media can be distinguished. In the past standard criteria to classify this new disorder were lacking. In DSM-5, nine criteria are proposed for diagnosing Internet gaming disorder. The focus is currently on video games as most studies have been done in this field. Prevalence estimations are difficult to interpret due to the lack of standard diagnostic measures and result in a range of the frequency of Internet addiction between 1 % and 4.2 % in the general German population. Rates are higher in younger individuals. For computer game addiction prevalence rates between 0.9 % and 1.7  % can be found in adolescents. Despite substantial comorbidity among those affected current research points to addictive media use as a stand-alone disorder.

Within social interactions, humans often experience interpersonal emotions such as embarrassment, shame, guilt, or pride. How interpersonal emotions are processed on the neural systems level is of major interest for social neuroscience research. While the configuration of laboratory settings in general is constraining for emotion research, recent neuroimaging investigations came up with new approaches to implement socially interactive and immersive scenarios for the real-life investigation of interpersonal emotions. These studies could show that among other brain regions the so-called mentalizing network, which is typically involved when we represent and make sense of others' states of mind, is associated with interpersonal emotions. The anterior insula/anterior cingulate cortex network at the same time processes one's own bodily arousal during such interpersonal emotional experiences. Current research aimed to explore how we make sense of others' emotional states during social interactions and investigates the modulating factors of our emotional experiences during social interactions. Understanding how interpersonal emotions are processed on the neural systems level may yield significant implications for neuropsychiatric disorders that affect social behavior such as social anxiety disorders or autism.

    The ability of a robot to localise itself and simultaneously build a map of its environment (Simultaneous Localisation and Mapping or SLAM) is a fundamental characteristic required for autonomous operation of the robot. Vision Sensors are very attractive for application in SLAM because of their rich sensory output and cost effectiveness. Different issues are involved in the problem of vision based SLAM and many different approaches exist in order to solve these issues. This paper gives a classification of state-of-the-art vision based SLAM techniques in terms of (i) imaging systems used for performing SLAM which include single cameras, stereo pairs, multiple camera rigs and catadioptric sensors, (ii) features extracted from the environment in order to perform SLAM which include point features and line/edge features, (iii) initialisation of landmarks which can either be delayed or undelayed, (iv) SLAM techniques used which include Extended Kalman Filtering, Particle Filtering, biologically inspired techniques like RatSLAM, and other techniques like Local Bundle Adjustment, and (v) use of wheel odometry information. The paper also presents the implementation and analysis of stereo pair based EKF SLAM for synthetic data. Results prove the technique to work successfully in the presence of considerable amounts of sensor noise. We believe that state of the art presented in the paper can serve as a basis for future research in the area of vision based SLAM. It will permit further research in the area to be carried out in an efficient and application specific way.

    Full Text Available Cyanobacteria are considered to be one of the most promising sources of new, natural products. Apart from non-ribosomal peptides and polyketides, ribosomally synthesized and post-translationally modified peptides (RiPPs are one of the leading groups of bioactive compounds produced by cyanobacteria. Among these, cyanobactins have sparked attention due to their interesting bioactivities and for their potential to be prospective candidates in the development of drugs. It is assumed that the primary source of cyanobactins is cyanobacteria, although these compounds have also been isolated from marine animals such as ascidians, sponges and mollusks. The aim of this review is to update the current knowledge of cyanobactins, recognized as being produced by cyanobacteria, and to emphasize their genetic clusters and chemical structures as well as their bioactivities, ecological roles and biotechnological potential.

    This study focused on the sediment contamination with some organic micropollutants based on the monitoring data together with available literature in Poland. The following persistent organic pollutants (POPs): polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and chlorinated pesticides (CP) were characterized in sediments with respect to current legislations in force. Based on accessible data, higher PAHs, PCBs and CP concentrations were found in river sediments than in lake sediments. Especially, sediments of the Oder River and its tributary in the southern part of Poland, were highly polluted. In order to minimize the risk of the secondary pollution of surface waters, it is necessary to introduce consolidated management system with sediments proceeding. Furthermore, it is also of great importance to elaborate specific regulations concerning conditions of sediments management.

    Allergy to natural rubber latex (NRL) reached epidemic proportions during the nineties and led to intense preventive efforts. The aim of this review was to provide a comprehensive compilation of the current status of occupational NRL allergy. Recent advances led to the characterization of 15 NRL allergens and the development of assays for measuring the allergen content of NRL materials and specific IgE antibodies against NRL allergen components. Preventive measures aimed at reducing workplace exposure to NRL allergens were associated with decreasing incidence rates of NRL allergy. However, a pooled analysis of epidemiological surveys published during the last 10 years provided prevalence estimates of NRL sensitization and allergy similar to those derived from studies conducted before 2003. Substantial progress has been made in the understanding and prevention of NRL allergy, although the disease may still remain a worldwide cause of concern.

    Full Text Available It is the objective of this paper to present the path which the wind farm projects have undergone in Croatia from their introduction and expansion since the year 2007 up to the today's date when their development is temporarily stayed. The paper first describes the political and legal framework for renewable energy sources in Croatia, and specifically for wind power plants, as well as the current status of investment in building of wind farms in Croatia. The paper further analyses why the Croatian system of promotion of eligible producers has proven to attract investment, albeit unsustainable for a longer period of time, and which regulatory measures have later contributed to the suspension of wind farm investment in 2014. Legal and factual consequences of such suspension are discussed at the end of the paper, as well as some potential new business models for further exploitation of wind energy in Croatia.

    The present paper is an analysis of the results of epidemiological studies in Belarus about the after-effects of the accident at the Chernobyl atomic power station (ChAPS), based on published data at scientific institutes, organs and institutions of Ministry of Health. In the last years the affected population showed thereby more significant - as compared with republican indices - growth of incidence in the majority of diseases (first of all: digestion, urogenital, nervous, endocrine systems, diseases of ear, throat, nose both among adults and among children). Aggravation of health state continues in the participants of liquidation of the ChAPS accident consequences and the evacuees from the alienation zone which have obtained considerable radiation load to organism (rise of incidence of diseases of endocrine, cardiovascular, nervous system etc.). Considerable growth of thyroid cancer incidence is registered in Belarus children and adolescents, especially in the Gomel and Brest regions. This is conditioned by dose commitments on thyroid gland due to iodine radionuclides in first period after the accident, incorrect iodine prophylaxy, and goitre endemic. The rise of hereditary pathology is registered too. An expressed increase of oncological diseases is observed therewith mainly in the Gomel region, especially in the districts with high level of radiocontamination and, consequently, significant radiation load. First of all, this relates to the growth of incidence of cancer of lungs, mammary gland, bladder. The analysis of epidemiological studies performed in Belarus after the ChAPS catastrophe and comparison of them with data obtained in the pre-Chernobyl period testify to the aggravation of health state of Belarus population. The specialists unambiguously recognize the direct influence of radioactive pollution in the environment on rise of thyroid pathologies, hereditary and congenial diseases, and cancers of different localizations.

    2016-09-01

    Full Text Available The paper is devoted to the study of the phenomenon of precarious employment in Russian regions. Today, the socio-economic sciences lack a single concept of precarious employment applicable to Russian conditions. Despite the considerable amount of scientific and practical works of domestic and foreign authors on the issue of precarious employment, the criteria of its statistical evaluation as applied to Russian conditions have not been determined. At the same time, the development of precarious employment threatens the country’s socio-economic welfare, because it creates the risk of unwanted effects such as poor employment, hidden and open unemployment, lower labor productivity, degradation of human capital, etc. The paper provides a brief review of research on the problem stated, and defines precarious employment. The author makes an attempt to determine and substantiate the list of indicators available in official statistics for assessing precarious employment in the region. The study allocates three blocks of indicators: indicators of institutional regulation, conditions of employment and functioning of the labor market. Based on these indicators, the author analyzes the status and trends of precarious work in the Vologda Oblast in the period from 2001 to 2015. In some cases, the author presents a comparative analysis of the data for the Russian Federation and Northwestern Federal District. The analysis has helped identify positive and negative changes in the field of precarious employment in the Vologda Oblast. In particular, the author identifies the following problems: an increase in the share of those employed in the informal sector, a relative increase in the number of the working poor, an almost three-fold growth of overdue debts on wages in comparable prices per worker. On the basis of this analysis, the author identifies the directions of the state policy that can help reduce precarious employment: development of information

    Recent research revealed that emotional content can be successfully decoded from human dance movement. Most previous studies made use of videos of actors or dancers portraying emotions through choreography. The current study applies emotion induction techniques and free movement in order to examine the recognition of emotional content from dance. Observers (N = 30) watched a set of silent videos showing depersonalized avatars of dancers moving to an emotionally neutral musical stimulus after emotions of either sadness or happiness had been induced. Each of the video clips consisted of two dance performances which were presented side-by-side and were played simultaneously; one of a dancer in the happy condition and one of the same individual in the sad condition. After every film clip, the observers were asked to make forced-choices concerning the emotional state of the dancer. Results revealed that observers were able to identify the emotional state of the dancers with a high degree of accuracy. Moreover, emotions were more often recognized for female dancers than for their male counterparts. In addition, the results of eye tracking measurements unveiled that observers primarily focus on movements of the chest when decoding emotional information from dance movement. The findings of our study show that not merely portrayed emotions, but also induced emotions can be successfully recognized from free dance movement.

A total of 225 secondary school students from two different countries enrolled in grades 8 and 11 (German sample; n = 94 and grade 9 (Swiss sample; n = 131 participated. Students' trait academic emotions of enjoyment, pride, anger, and anxiety in mathematics were assessed with a self-report questionnaire, whereas to assess their state academic emotions experience-sampling method was employed. The results revealed that students' scores on the trait assessment of emotions were generally higher than their scores on the state assessment. Further, as expected, students' academic self-concept in the domain of mathematics was shown to partly explain the discrepancy between scores on trait and state emotions. Our results indicate that there is a belief-driven discrepancy between what students think they feel (trait assessment and what they really feel (state assessment. Implications with regard to the assessment of self-reported emotions in future studies and practical implications for the school context are discussed.

  12. Negative mood state enhances the susceptibility to unpleasant events: neural correlates from a music-primed emotion classification task.

    Directory of Open Access Journals (Sweden)

    Jiajin Yuan

    Full Text Available BACKGROUND: Various affective disorders are linked with enhanced processing of unpleasant stimuli. However, this link is likely a result of the dominant negative mood derived from the disorder, rather than a result of the disorder itself. Additionally, little is currently known about the influence of mood on the susceptibility to emotional events in healthy populations. METHOD: Event-Related Potentials (ERP were recorded for pleasant, neutral and unpleasant pictures while subjects performed an emotional/neutral picture classification task during positive, neutral, or negative mood induced by instrumental Chinese music. RESULTS: Late Positive Potential (LPP amplitudes were positively related to the affective arousal of pictures. The emotional responding to unpleasant pictures, indicated by the unpleasant-neutral differences in LPPs, was enhanced during negative compared to neutral and positive moods in the entire LPP time window (600-1000 ms. The magnitude of this enhancement was larger with increasing self-reported negative mood. In contrast, this responding was reduced during positive compared to neutral mood in the 800-1000 ms interval. Additionally, LPP reactions to pleasant stimuli were similar across positive, neutral and negative moods except those in the 800-900 ms interval. IMPLICATIONS: Negative mood intensifies the humans' susceptibility to unpleasant events in healthy individuals. In contrast, music-induced happy mood is effective in reducing the susceptibility to these events. Practical implications of these findings were discussed.

    The guided imagery training is considered as an effective method and therefore widely used in modern cognitive psychotherapy, while less is known about the effectiveness of self-guided. The present study investigated the effects of regular use of self-guided positive imagery, applying both subjective (assessment of the psycho-emotional state) and objective (electroencephalographic, EEG) approaches to research. Thirty healthy subjects participated in the cognitive imagery-training program for 12 weeks. The schedule began with group training with an instructor for 2 days, where the participants learned various techniques of positive imagery, after which they continued their individual training at home. Psychological and EEG evaluations were applied at the baseline and at the end of the training period. The impact of training on the psycho-emotional states of the participants was evaluated through: Center for epidemiologic studies- Depression (CES-D) 20 item scale, Satisfaction with life scale (SWLS) and General Self-Efficacy scale (GSE). EEGs (19-channels) were recorded at rest with eyes closed. EEG analysis was performed using Low resolution electromagnetic tomography (LORETA) software that allows the comparison of current source density (CSD) and functional connectivity (lagged phase and coherence) in the default mode network before and after a workout. Initial assessment with CES-D indicated that 22 participants had subthreshold depression. After the training participants had less prominent depressive symptoms (CES-D, p = 0.002), were more satisfied with their lives (SWLS, p = 0.036), and also evaluated themselves as more effective (GSE, p = 0.0002). LORETA source analysis revealed an increase in the CSD in the right mPFC (Brodmann area 10) for beta-2 band after training (p = 0.038). LORETA connectivity analysis demonstrated an increase in lagged coherence between temporal gyruses of both hemispheres in the delta band, as well as between the Posterior cingulate

    Myocarditis, i.e. inflammation of the myocardium, is one of the leading causes of sudden cardiac death (SCD) and dilated cardiomyopathy (DCM) in young adults, and is an important cause of symptoms such as chest pain, dyspnea and palpitations. The pathophysiological process of disease progression leading to DCM involves an ongoing inflammation as a result of a viral-induced auto-immune response or a persisting viral infection. It is therefore crucial to detect the disease early in its course and prevent persisting inflammation that may lead to DCM and end-stage heart failure. Because of the highly variable clinical presentation, ranging from mild symptoms to severe heart failure, and the limited available diagnostic tools, the evaluation of patients with suspected myocarditis represents an important clinical dilemma in cardiology. New approaches for the diagnosis of myocarditis are needed in order to improve recognition, to help unravel its pathophysiology, and to develop new therapeutic strategies to treat the disease. In this review, we give a comprehensive overview of the current diagnostic strategies for patients with suspected myocarditis, and demonstrate several new techniques that may help to improve the diagnostic work-up.

    Intlekofer, Andrew M; Younes, Anas

    2014-10-01

    Modern advances in genomics and cancer biology have produced an unprecedented body of knowledge regarding the molecular pathogenesis of lymphoma. The diverse histological subtypes of lymphoma are molecularly heterogeneous, and most likely arise from distinct oncogenic mechanisms. In parallel to these advances in lymphoma biology, several new classes of molecularly targeted agents have been developed with varying degrees of efficacy across the different types of lymphoma. In general, the development of new drugs for treating lymphoma has been mostly empiric, with a limited knowledge of the molecular target, its involvement in the disease, and the effect of the drug on the target. Thus, the variability observed in clinical responses likely results from underlying molecular heterogeneity. In the era of personalized medicine, the challenge for the treatment of patients with lymphoma will involve correctly matching a molecularly targeted therapy to the unique genetic and molecular composition of each individual lymphoma. In this Review, we discuss current and emerging biomarkers that can guide treatment decisions for patients with lymphoma, and explore the potential challenges and strategies for making biomarker-driven personalized medicine a reality in the cure and management of this disease.

    To explore medical oncologists' and audiologists' knowledge and attitudes regarding ototoxicity monitoring, and to gain an understanding of monitoring currently being implemented at District Health Boards (DHBs) nationwide. We also aimed to identify ways in which audiological outcomes for patients receiving potentially ototoxic treatments could be improved, including examining whether the formulation and implementation of a national ototoxicity monitoring guideline is necessary. Complementary telephonic interviews were conducted with 16 senior or charge audiologists and seven senior medical oncologists from DHBs across New Zealand, and their responses analysed. Responses indicate a comprehensive understanding of ototoxicity across both disciplines; however there is limited familiarity with ototoxicity monitoring protocols. Patients across New Zealand undergo significantly variable ototoxicity monitoring; local practices range from no routine monitoring to audiological assessment prior to each cycle of chemotherapy. No routine audiological follow up is conducted post completion of treatment at any DHB, in contrast with international guidelines. Twenty-two of 23 participants were in favour of development of a national ototoxicity monitoring guideline. There is significant discrepancy in how ototoxicity monitoring is conducted across New Zealand, and implementation of a national ototoxicity monitoring protocol may improve audiological outcomes for patients receiving ototoxic chemotherapy.

    Clinical pharmacology in Russia has long history and is currently active, but rather unrecognized internationally. It is governmentally approved as a teaching/scientific specialty since 1983 and as a medical specialty since 1997. Courses of clinical pharmacology are included in the undergraduate curricula in the 5th and/or 6th year of education at all medical schools in the Russian Federation. Postgraduate education includes initial specialization in internal medicine with further residency in clinical pharmacology. Governmental legislation recommends that every healthcare institution has either a department or a single position of clinical pharmacologist. Major routine duties include information about and monitoring of medication use, consultations in difficult clinical situations, pharmacogenetic counseling, therapeutic drug monitoring, pharmacovigilance, and participation in drug and therapeutics (formulary) committees. There are official experts in clinical pharmacology in Russia responsible for coordinating relevant legislative issues. The chief expert clinical pharmacologist represents the discipline directly at the Ministry of Health. Research in clinical pharmacology in Russia is extensive and variable, but only some of it is published internationally. Russia is a participant of international societies of clinical pharmacology and therapeutics and collaboration is actively ongoing. There are still certain problems related to the development of the discipline in Russia-some healthcare institutions do not see the need for clinical pharmacology. However, the number of clinical pharmacologists in Russia is increasing as well as their role in physicians' education, national healthcare, and research.

    Full Text Available Phylloid (leaf-shaped breast tumors are a rare disease and constitute 0.3–0.5% of all breast tumors. Due to the rare frequency of occurrence, as well as the small number of randomized studies that have been conducted on this pathology, there is currently no standardized approach to the diagnosis and treatment of phylloid tumors. The reports about these rare cases appearing in the literature are, as a rule, descriptive, which only emphasizes the difficulty of differential diagnosis, the development of the correct tactics for treating such patients. In connection with the rarity, it is very difficult to diagnose correctly this pathology, which requires a highly qualified doctor as a diagnostician in the initial contact with such a patient, and a pathologist doctor who establishes the final morphological diagnosis. Often, leaf-shaped tumors are mistaken for mammary fibroadenomas. Such difficulties in correct diagnosis in the preoperative period can lead to errors in the planning of treatment. Also, the recommendations for the treatment of patients with this diagnosis are not fully understood, since up to now there are no accepted treatment standards in both Russian and foreign recommendations. Due to the fact that this pathology of mammary glands is rare, the principles of treatment are based on small retrospective studies and clinical observations. In this review, we will discuss the results of major retrospective studies, including data on epidemiology, etiology, diagnostic approach, strategies and results of treatment of this complex group of breast pathologies.

    Medical science is divided into basic medical science and clinical medicine, and the technology of the medical treatment is established as their aggregate power. This concept can be compared with the presence of industrial engineering as a product of physical science and engineering. Basic medical science has come to be combined with science deeply as a result of the rise of recent molecular biology. As to clinical medicine, current highly advanced medical treatment can be said to be made up of scientific technology. Medical treatment can be considered to include prevention, diagnosis, remedy, and rehabilitation stages. It is closely connected with engineering in each stage. The methods of approaching medical science are elucidation of the functions of internal organs and tissue considering that a living body is a plant, and offering of new therapeutical means by applying chemical devices to a living body. The functions of artificial organs can e divided roughly into convection transport, mass transfer, structural members, and signal transfer from the viewpoint of chemical engineering. Medical treatment will be brought into close relation with scientific technology in the future. 10 refs., 3 figs., 2 tabs.

    Since the first demonstrations that mindfulness-based therapies could have a positive influence on chronic pain patients, numerous studies have been conducted with healthy individuals in an attempt to understand meditative analgesia. This review focuses explicitly on experimental pain studies of meditation and attempts to draw preliminary conclusions based on the work completed in this new field over the past 6 years. Dividing meditative practices into the broad categories of focused attention (FA) and open monitoring (OM) techniques allowed several patterns to emerge. The majority of evidence for FA practices suggests they are not particularly effective in reducing pain. OM, on the other hand, seems to influence both sensory and affective pain ratings depending on the tradition or on whether the practitioners were meditating. The neural pattern underlying pain modulation during OM suggests meditators actively focus on the noxious stimulation while inhibiting other mental processes, consistent with descriptions of mindfulness. A preliminary model is presented for explaining the influence of mindfulness practice on pain. Finally, the potential analgesic effect of the currently unexplored technique of compassion meditation is discussed.

    Prostate-specific antigen testing and prostate biopsy have revolutionized our ability to detect prostate cancer at an early stage. The transrectal ultrasound-guided biopsy procedure has undergone a number of modifications over the past 10 years to meet our goal of early detection of cancer at a curable stage. Biopsy schemes have evolved from lesion-directed biopsies to systematic mapping of the peripheral zone of the prostate, which harbors almost all of the significant tumor foci. An increase in the number of biopsy cores from 6 to 10 (or 12) has resulted in a significant improvement in the detection of clinically localized cancer, without any appreciable increase in the number of indolent cancers. Current biopsy schemes also have enhanced our ability to determine the true prognostic value of pathologic lesions such as high-grade prostatic intraepithelial neoplasia and atypical small acinar proliferation which have been associated with cancer detection in repeat biopsies. I discuss the rationale behind, and the outcomes of, various biopsy strategies. More than 15 years after PSA testing was popularized for early detection, a number of men are presenting for evaluation regarding repeat prostate biopsy for various clinical indications. The indications, biopsy scheme, and cancer detection rates for repeat prostate biopsy are discussed in detail.

    Despite the fact that Malaysian public institutions have progressed considerably on website and portal usage, web accessibility has been reported as one of the issues deserves special attention. Consistent with the government moves to promote an effective use of web and portal, it is essential for the government institutions to ensure compliance with established standards and guidelines on web accessibility. This paper evaluates accessibility of 25 Malaysian ministries websites using automated tools i.e. WAVE and Achecker. Both tools are designed to objectively evaluate web accessibility in conformance with Web Content Accessibility Guidelines 2.0 (WCAG 2.0) and United States Rehabilitation Act 1973 (Section 508). The findings reported somewhat low compliance to web accessibility standard amongst the ministries. Further enhancement is needed in the aspect of input elements such as label and checkbox to be associated with text as well as image-related elements. This findings could be used as a mechanism for webmasters to locate and rectify errors pertaining to the web accessibility and to ensure equal access of the web information and services to all citizen.

    The authors reviewed the seminal and more recent literature surrounding the major modalities for percutaneous left atrial appendage closure used in contemporary practice, with particular emphasis on safety and efficacy, technical challenges, and future developments. Along with the continued practice of surgical left atrial appendage closure, which has evolved substantially with the advent of clipping techniques, a number of percutaneous methods have been developed to close the left atrial appendage with endocardial, epicardial, and hybrid approaches. The last 18 months has seen the Food and Drug Administration approval of the WATCHMAN device for stroke prevention in the United States, the initiation of a randomized controlled trial to further examine the LARIAT device, and an increasing body of literature surrounding use of the AMPLATZER Amulet in Europe. Left atrial appendage closure is a promising alternative to systemic anticoagulation for stroke prevention in appropriate atrial fibrillation patients. The wealth of available data for the various modalities sheds light on the strengths and limitations of each, postprocedural complications and their management, and new areas for exploration. With a plethora of new devices on the horizon, it is a very exciting time in the field of 'appendage-ology' as we pursue new avenues to optimize care for atrial fibrillation patients.

    In recent years, metabolomics developed to an accepted and valuable tool in life sciences. Substantial improvements of analytical hardware allow metabolomics to run routinely now. Data are successfully used to investigate genotype-phenotype relations of strains and mutants. Metabolomics facilitates metabolic engineering to optimise mircoorganisms for white biotechnology and spreads to the investigation of biotransformations and cell culture. Metabolomics serves not only as a source of qualitative but also quantitative data of intra-cellular metabolites essential for the model-based description of the metabolic network operating under in vivo conditions. To collect reliable metabolome data sets, culture and sampling conditions, as well as the cells' metabolic state, are crucial. Hence, application of biochemical engineering principles and method standardisation efforts become important. Together with the other more established omics technologies, metabolomics will strengthen its claim to contribute to the detailed understanding of the in vivo function of gene products, biochemical and regulatory networks and, even more ambitious, the mathematical description and simulation of the whole cell in the systems biology approach. This knowledge will allow the construction of designer organisms for process application using biotransformation and fermentative approaches making effective use of single enzymes, whole microbial and even higher cells.

    Insufficient pain education is problematic across the health care spectrum. Recent educational advancements have been made to combat the deficits in pain education to ensure that health care professionals are proficient in assessing and managing pain. The purpose of this survey was to determine the extent of pain education in current Doctorate of Physical Therapy schools in the United States, including how pain is incorporated into the curriculum, the amount of time spent teaching about pain, and the resources used to teach about pain. The survey consisted of 10 questions in the following subject areas: basic science mechanisms and concepts about pain, pain assessment, pain management, and adequacy of pain curriculum. The overall response was 77% (167/216) for the first series of responses of the survey (Question 1), whereas 62% completed the entire survey (Questions 2-10). The average contact hours teaching about pain was 31 ± 1.8 (mean ± standard error of the mean) with a range of 5 to 115 hours. The majority of schools that responded covered the science of pain, assessment, and management. Less than 50% of respondents were aware of the Institute of Medicine report on pain or the International Association for the Study of Pain guidelines for physical therapy pain education. Only 61% of respondents believed that their students received adequate education in pain management. Thus, this survey demonstrated how pain education is incorporated into physical therapy schools and highlighted areas for improvement such as awareness of recent educational advancements. This article demonstrates how pain education is incorporated into physical therapy curricula within accredited programs. Understanding the current structure of pain education in health professional curriculum can serve as a basis to determine if recent publications of guidelines and competencies impact education.

    2015-01-01

    Full Text Available Introduction : Cancer pain is chronic pain resulting from various mechanisms related to the natural history of the disease, the course of therapy, and psychosocial factors. Aim of the research : To assess the relationship between the intensity of cancer pain in women at the final stage of chemotherapy following radical surgery of breast cancer, and the intensity of negative emotional reactions. Material and methods : The study was conducted in a population of 118 women after radical surgical treatment of breast cancer and undergoing chemotherapy at the Chemotherapy Unit of the Holycross Cancer Centre in Kielce in 2011. The research methodology consisted of a diagnostic survey and medical documentation review. Results: Strong emotional stress manifested by anxiety and depression was experienced by 48.3% and 29.7% of patients, respectively. Aggression was experienced by 15.2%. Intensification of pain was associated with the intensification of anxiety (r = 0.37; p < 0.0001, depression (r = 0.35; p < 0.01, and aggression (r = 0.30; p < 0.01. Conclusions: Adherence to the WHO-recommended analgesic ladder regimen is an effective means to treat chronic cancer pain in women in the final stage of chemotherapy following radical surgical treatment. Effective pharmacotherapy of cancer pain significantly contributes to a reduction in the intensity of negative emotional reactions, i.e. anxiety, depression, and aggression in patients undergoing chemotherapy following mastectomy. Breast cancer chemotherapy is associated with high levels of anxiety, pain, and aggression being experienced by the patients. Pain is an important determinant of the emotional state of women undergoing chemotherapy following radical cancer surgery.

  7. Current state and use of biological adhesives in orthopedic surgery.

    Bone and tissue adhesives are common and beneficial supplements to standard methods of musculoskeletal tissue suture repair. Knowledge and development of biologically derived or inspired adhesives useful in orthopedic surgery are rapidly advancing. Recent literature demonstrates the increased adjunct or primary use of biological adhesives in the repair of musculoskeletal soft tissues, chondral fractures, and osteochondral fractures. Adhesives offer more benefits and enhancements to tissue healing than current fixation methods afford, including improved biocompatibility, resorbability, and non-immunogenicity. Further investigation is required to determine the extent of the role that these bioadhesives can play in orthopedic surgery. The largest group of biologically derived adhesives and sealants is fibrin sealants, which include first- and second-generation commercially available fibrin sealants, autologous fibrin sealants, and variants. Other groups include gelatin-resorcin aldehydes, protein-aldehyde systems, collagen-based adhesives, polysaccharide- based adhesives, mussel adhesive proteins, and various biologically inspired or biomimetic glues. Potential uses include applications in orthopedic-related blood conservation, arthroplasty, articular cartilage disorders, sports medicine, spine surgery, trauma, and tumors. The development of an adhesive with universal application is likely unfeasible, given the unique characteristics of various musculoskeletal tissues. However, the literature demonstrates the overall underuse of adhesives and indicates the rising probability of the development of a successful variety of bioadhesives for use in orthopedic surgery. As a result of reading this article, physicians should be able to: 1. Describe the difference between adhesives and sealants. 2. Recognize fibrin adhesives commonly used in practice today and identify other biological adhesives with rising potential. 3. Analyze how fibrin sealants work relative to fibrin and

    Inflammatory bowel disease (IBD) is one of the five most prevalent gastrointestinal disease burdens in the US, with an overall health care cost of more than USD 1.7 billion. It commonly requires a lifetime of care, and accounts for more than 700,000 physician visits, 100,000 hospitalizations, and disability in 119,000 patients each year. IBD is a multifactorial disease and comprises genetic susceptibility, uncontrolled immune responses, and environmental factors which play a role in the pathogenesis and course of the disease. IBD patients are lifelong on medication, either for induction or maintenance therapy. Current treatment option (corticosteroids, immune suppressants, biologics), administered in mono- or combination therapy, are still unsatisfactory. Due to the nature of disease, 20-40% of patients relapse within the first 12 months. Although modern treatment algorithms have diminished the risk of surgery, the treatments harbor significant side effects, which impacts patients' quality of life. The role of nutrition in IBD has gathered high interest, especially in pediatric Crohn's disease, where studies have shown that exclusive enteral nutrition can induce remission in mild-to-moderate disease comparable to corticosteroids. Thus, gastroenterologists and patients become increasingly aware that specific nutritional interventions offered in addition to the standard of care are an appealing option for a safe long-term disease management. Such specific nutritional solutions should be based on scientific/clinical evidence and specifically designed to address the patients' distinct nutritional requirements. As per definition, these nutrition products fall under the regulatory framework of a Medical Food (Foods for Special Medical Purposes in Europe).

    Tobacco use is the leading cause of preventable disease and death in the United States, and cigarettes are the most commonly used tobacco product among U.S. adults (1,2). To assess progress toward achieving the Healthy People 2020 target of reducing the proportion of U.S. adults who smoke cigarettes to ≤12.0% (objective TU1.1),* CDC assessed the most recent national estimates of cigarette smoking prevalence among adults aged ≥18 years using data from the 2015 National Health Interview Survey (NHIS). The proportion of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 15.1% in 2015, and the proportion of daily smokers declined from 16.9% to 11.4%. However, disparities in cigarette smoking persist. In 2015, prevalence of cigarette smoking was higher among adults who were male; were aged 25-44 years; were American Indian/Alaska Native; had a General Education Development certificate (GED); lived below the federal poverty level; lived in the Midwest; were insured through Medicaid or were uninsured; had a disability/limitation; were lesbian, gay, or bisexual; or who had serious psychological distress. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, anti-tobacco mass media campaigns, and barrier-free access to tobacco cessation counseling and medications, are critical to reducing cigarette smoking and smoking-related disease and death among U.S. adults, particularly among subpopulations with the highest smoking prevalences (3).

    The legal basis for soil protection in the Federal Republic of Germany is: -The Act on Protection against Harmful Changes to Soil and on Rehabilitation of Contaminated Sites (Federal Soil Protection Act) (Bundes-Bodenschutzgesetz - BBodSchG) of 1998 [1] -The Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV) of 1999 [2]. In Germany, the Federal Government has legislative competence in the field of soil protection. The Lander (German federal states), in turn, are responsible for enforcement of the BBodSchG and the BBodSchV; they may also issue supplementary procedural regulations. According to Article 1 BBodschG, the purpose of the Act is inter alia to protect and restore the functions of the soil on a permanent sustainable basis. These actions shall include prevention of harmful soil changes as well as rehabilitating soil, contaminated sites and waters contaminated by such sites in such a way that any contamination remains permanently below the hazard threshold. Whilst prevention aims to protect and preserve soil functions on a long-term basis, the object of remediation is mainly to avert concrete hazards in a spatial, temporal and manageable causative context. ''Remedial soil protection'' encompasses a tiered procedure in which a suspicion is verified successively and with least-possible effort and in which the circumstances of the individual case at hand are taken into account in deciding whether or not a need for remediation exists. It comprises the systematic stages of identifying, investigating and assessing suspect sites and sites suspected of being contaminated with a view to their hazard potential, determining whether remediation is necessary, remediating identified harmful soil changes and contaminated sites, and carrying out, where necessary, aftercare measures following final inspection of the remedial measure.

    The temperature dependence of the current-voltage characteristics of high-quality thin films of tin from 7 to 50 {mu}m thick are investigated in the absence of an external magnetic field. For the first time, we have experimentally observed phase slip centres (PSCs) and phase slip lines (PSLs) on the same superconducting tin film with known parameters in the temperature intervals corresponding to the mechanisms of their formation and existence. We have shown that the states of a wide film with increasing transport current appear in the following order: the superconducting state for current less than critical; the resistive vortex state for current more than critical, but less than maximum current for the uniform flux flow (instability current); the critical state due to the onset of instability of the steady pattern of viscous motion of the vortices; a vortex-free resistive state with PSLs for current more than instability current, but less than the upper critical current; and the normal state at a current higher than the upper critical current.

    LED's have been commercially available since the 1960's. For many years they were used primarily for indicator applications. The remarkable increase in materials technology and efficiency that has been achieved since the early 1990's for AlInGaP red and amber LEDs, and InGaN green and blue LEDs, has enabled the penetration of markets such as outdoor display, signaling, and automotive brake light and turn signal applications. White LEDs, which are either blue LEDs combined with a phosphor, or a combination of red, green, and blue LEDs, are being used in emerging applications such as cell phone flash, television backlights, projection, and automotive headlights. In addition, to efficiency improvements these applications have required the development of higher power packages and, in some of these applications which are etendue limited, higher luminance devices. High power devices are commercially available which are capable of 140 lumens output and have an efficacy of around 70 lm/W for white emission. New package and chip technologies have been demonstrated which have a luminance of 38 mega nits (Mcd/m^2), approximately 50% more luminance than that of an automotive headlamp halogen bulb (˜25 mega nits). The recent progress in materials technology, packaging, and chip technology makes it clear that LED's will become important for general illumination applications. The rate of LED penetration of this market will depend upon continued increases in performance and lower costs as well as better control of the white spectral emission. Efficiency, current density, and costs are closely linked because the cost in dollars/lumen is inversely proportional to how many lumens can be realized from each unit of device area for a given device type. Performance as high as 138 lm/W, and over 40% wall plug efficiency, has been reported for low power research devices and over 90 lm/W for high power research devices. It is clear that high power commercial products with performance in

    Research on adolescent same-sex sexuality has focused almost exclusively on risk in the lives of self-identified lesbians, gays, and bisexuals. The attention to same-sex self identity may obscure heterogeneity in same-sex romance (attractions and relationships) and thus may inaccurately characterize sexual-minority youth as more different than heterosexual youth in terms of emotional health risk. Using data from the National Longitudinal Study of Adolescent Health, we examine the nexus of romantic attractions and relationships among contemporary U.S. adolescents, linking experiences of romance to indicators of emotional health. We conclude that broadening the scope of inquiry beyond binaries of identity (that is, gay vs. straight) provides the opportunity to more fully understand the health and well-being of all adolescents.

    Currently, an estimated 25-30% of people ages 85 or older have dementia, with a projected 115 million people worldwide living with dementia by 2050. With this worldwide phenomenon fast approaching, early detection of at-risk older adults and development of interventions focused on preventing loss in quality of life are increasingly important. A new construct defined by the International Consensus Group (I.A.N.A/I.A.G.G) as «cognitive frailty» combines domains of physical frailty with cognitive impairment and provides a framework for research that may provide a means to identify individuals with cognitive impairment caused by nonneurodegenerative conditions. Using the integrative review method of Whittemore and Knafl., 2005 this study examines and appraises the optimal measures for detecting cognitive frailty in clinical populations of older adults. The integrative review was conducted using PubMed, CINAHL, Web of Science, PsycInfo, and ProQuest Dissertations and Theses. From the total 185 articles retrieved, review of titles and key words were conducted. Following the initial review, 168 articles did not meet the inclusion criteria for association of frailty and cognition. Of the 18 fulltext articles reviewed, 11 articles met the inclusion criteria; these articles were reviewed in-depth to determine validity and reliability of the cognitive frailty measures. Predictive validity was established by the studies reviewed in four main areas: frailty and type of dementia MCI (OR 7.4, 95% CI 4.2-13.2), vascular dementia (OR 6.7, 95% CI 1.6-27.4) and Alzheimer's dementia (OR 3.2, 95% CI 1.7-6.2), frailty and vascular dementia (VaAD) is further supported by the rate of change in frailty x macroinfarcts (r = 0.032, p < 0.001); frailty and the individual domains of cognitive function established with the relationship of neurocognitive speed and change in cognition using regression coefficients; individual components of frailty and individual domains of cognitive function

    Full Text Available Multiday ultra-endurance races present athletes with a significant number of physiological and psychological challenges. We examined emotions, the perceived functionality (optimal-dysfunctional of emotions, strategies to regulate emotions, sleep quality, and energy intake-expenditure in a four-man team participating in the Race Across AMerica (RAAM; a 4856km continuous cycle race. Cyclists reported experiencing an optimal emotional state for less than 50% of total competition, with emotional states differing significantly between each cyclist over time. Coupled with this emotional disturbance, each cyclist experienced progressively worsening sleep deprivation and daily negative energy balances throughout the RAAM. Cyclists managed less than one hour of continuous sleep per sleep episode, high sleep latency and high percentage moving time. Of note, actual sleep and sleep efficiency were better maintained during longer rest periods, highlighting the importance of a race strategy that seeks to optimise the balance between average cycling velocity and sleep time. Our data suggests that future RAAM cyclists and crew should: 1 identify beliefs on the perceived functionality of emotions in relation to best (functional-optimal and worst (dysfunctional performance as the starting point to intervention work; 2 create a plan for support sufficient sleep and recovery; 3 create nutritional strategies that maintain energy intake and thus reduce energy deficits; and 4 prepare for the deleterious effects of sleep deprivation so that they are able to appropriately respond to unexpected stressors and foster functional working interpersonal relationships

    Full Text Available The article examines the features of actualization of emotions in a non-verbal speech behavior of the character of a literary text. Emotions are considered basic, the most actively used method of literary character reaction to any object, action, or the communicative situation. Nonverbal ways of expressing emotions more fully give the reader an idea of the emotional state of the character. The main focus in the allocation of non-verbal means of communication in art is focused on the description of kinetic, proxemic and prosodic components. The material of the study is the microdialogue fragments extracted by continuous sampling of their works of art texts of the Russian-speaking and German-speaking classical and modern literature XIX - XX centuries. Fragments of the dialogues were analyzed, where the recorded voice of nonverbal behavior of the character of different emotional content (surprise, joy, fear, anger, rage, excitement, etc. was fixed. It was found that means of verbalization and descriptions of emotion of nonverbal behavior of the character are primarily indirect nomination, expressed verbal vocabulary, adjectives and adverbs. The lexical level is the most significant in the presentation of the emotional state of the character.

    Full Text Available The dorsolateral prefrontal cortex (DLPFC is generally thought to be involved in affect and emotional processing; however, the specific contribution of each hemisphere continues to be debated. In the present study, we employed unilateral tDCS to test the unique contribution of left DLPFC in the encoding and retrieval of emotional stimuli in healthy subjects. Forty-two right handed undergraduate students received either anodal, cathodal or sham stimulation of left DLPFC while viewing neutral, pleasant, and unpleasant pictures. After completing a filler task, participants were asked to remember as many pictures as possible. Results showed that participants were able to remember a larger amount of emotional (both pleasant and unpleasant pictures than of neutral ones, regardless of the type of tDCS condition. Participants who received anodal stimulation recalled a significantly higher number of pleasant images than participants in the sham and cathodal conditions, while no differences emerged in the recall of neutral and unpleasant pictures. We conclude that our results provide some support to the role of left prefrontal cortex in the encoding and retrieval of pleasant stimuli.

  19. Emotionally Colorful Reflexive Games

    2011-01-01

    This study addresses the matter of reflexive control of the emotional states by means of Reflexive Game Theory (RGT). It is shown how to build a bridge between RGT and emotions. For this purpose the Pleasure-Arousal-Dominance (PAD) model is adopted. The major advantages of RGT are its ability to predict human behavior and unfold the entire spectra of reflexion in the human mind. On the other hand, PAD provides ultimate approach to model emotions. It is illustrated that emotions are reflexive processes and, consequently, RGT fused with PAD model is natural solution to model emotional interactions between people. The fusion of RGT and PAD, called Emotional Reflexive Games (ERG), inherits the key features of both components. Using ERG, we show how reflexive control can be successfully applied to model human emotional states. Up to date, EGR is a unique methodology capable of modeling human reflexive processes and emotional aspects simultaneously.

    2007-01-01

    The ground-state entanglement associated with a three-spin transverse Ising model is studied. By introducing an energy current into the system, a quantum phase transition to energy-current phase may be presented with the variation of external magnetic field; and the ground-state entanglement varies suddenly at the critical point of quantum phase transition. In our model, the introduction of energy current makes the entanglement between any two qubits become maximally robust.

    2009-09-10

    Predictions of quasi steady state DT plasmas in ITER are generated using the PTRANSP code. The plasma temperatures, densities, boundary shape, and total current (9 - 10 MA) anticipated for ITER steady state plasmas are specified. Current drive by negative ion neutral beam injection, lower-hybrid, and electron cyclotron resonance are calculated. Four modes of operation with different combinations of current drive are studied. For each mode, scans with the NNBI aimed at differing heights in the plasma are performed to study effects of current control on the q profile. The timeevolution of the currents and q are calculated to evaluate long duration transients. Quasi steady state, strongly reversed q profiles are predicted for some beam injection angles if the current drive and bootstrap currents are sufficiently large.

  5. Selective attention to food-related stimuli in hunger: are attentional biases specific to emotional and psychopathological states, or are they also found in normal drive states?

    Science.gov (United States)

    1998-02-01

    Previous work has indicated that anxiety disorders and eating disorders are associated with selective processing of stimuli relevant to patients' concerns (e.g. Mathews and MacLeod, 1994; Annual Review of Psychology, 45, 25-50; Channon et al., 1988; British Journal of Clinical Psychology, 27, 259-260). A dot probe task was used to investigate whether attentional biases are also a feature of a normal drive state. Specifically, we examined whether hunger is associated with biases in selective attention and in pre-attentive processes for food-relevant stimuli. Subjects with high levels of hunger showed a greater attentional bias for food-related words presented in a suprathreshold exposure condition (words shown for 500 msec), in comparison with those with low hunger. There was no evidence in the present study of a hunger-related bias in pre-attentive processes (i.e. when words were shown for 14 msec and masked). Results suggest that a non-emotional motivational state, such as hunger, is associated with a bias in certain aspects of information processing, such as selective attention, for stimuli that are relevant to the motivational state. Findings are discussed in relation to recent research into emotion-related cognitive biases.

    2015-01-01

    Previous research on mindfulness has focused mainly on stress-related negative symptoms and short-term effects. In contrast, the present article focuses on the impact of a mindfulness-based stress reduction (MBSR) program on improving well-being (i.e. relaxation states and related positive emotions) in a longitudinal study for a period of one year. A randomized controlled trial in a sample of 42 physicians was used. The intervention group participated in an 8-week MBSR program, with an additional 10-month maintenance period and completed measures of mindfulness and relaxation at pre-intervention, post-intervention and after 10 months. Heart rate measures were also obtained. Significant improvements in favor of the experimental group compared with the control group on the levels of mindfulness and relaxation (including positive emotional states, such as at ease/peace, renewal, energy, optimism, happiness, acceptance, and even transcendence) were obtained after eight weeks. Remarkably, change magnitudes (effect size) significantly increased at the end of the maintenance period after a year, especially for mindfulness and positive energy. Additionally, heart rate significantly decreased for the intervention group and maintained a year after the beginning of the treatment. Results are relevant in terms of practical consequences for improving health and well-being in this population and also in terms of cost-efficiency.

    Fredrickson, Barbara L.; Tugade, Michele M.; Waugh, Christian E.; Larkin, Gregory R.

    2009-01-01

    Extrapolating from B. L. Fredrickson's (1998, 2001) broaden-and-build theory of positive emotions, the authors hypothesized that positive emotions are active ingredients within trait resilience. U.S. college students (18 men and 28 women) were tested in early 2001 and again in the weeks following the September 11th terrorist attacks. Mediational analyses showed that positive emotions experienced in the wake of the attacks— gratitude, interest, love, and so forth—fully accounted for the relations between (a) precrisis resilience and later development of depressive symptoms and (b) precrisis resilience and postcrisis growth in psychological resources. Findings suggest that positive emotions in the aftermath of crises buffer resilient people against depression and fuel thriving, consistent with the broaden-and-build theory. Discussion touches on implications for coping. PMID:12585810

    Pain is a multidimensional experience with sensory-discriminative, cognitive-evaluative and affective-motivational components. Emotional factors such as unpleasantness or anxiety are known to have influence on pain in humans. The aim of this single-blinded, cross over study was to evaluate the effects of transcranial direct current stimulation (tDCS) on emotional aspects of pain in pain alleviation. Fifteen subjects (5 females, 10 males) volunteered to participate in this study. In an oddball paradigm, three categories of 20 pictures (unpleasant, neutral, and pleasant) served as rare target pictures from the International Affective Picture System (IAPS). The power of the delta (1-4 Hz), theta (4-8 Hz), alpha (8-12 Hz), beta (12-25 Hz), and gamma (30-40 Hz) frequency bands in the three categories were measured using electroencephalography during an oddball paradigm at pre- and post-anodal or sham tDCS above the left dorsolateral prefrontal cortex (DLPFC). Results showed that the beta band power was significantly increased, and the alpha band power was significantly decreased during unpleasant pictures after anodal tDCS compared with sham tDCS. Furthermore, regarding unpleasant pictures, subjective reports of Self Assessment Manikin (SAM) for emotional valence after anodal tDCS showed a significant decrease of unpleasantness. Therefore, emotional aspects of pain may be effectively alleviated by tDCS of the left DLPFC as was shown not only by subjective evaluation, but also by objective observation of cerebral neural activity. This processing may be mediated by facilitation of the descending pain inhibitory system through enhancing neural activity of the left DLPFC.

    Full Text Available Relations between Neuroticism, Republican-Democrat preference, and conservative-liberal ideological orientation were examined with the states of the USA as units of analysis. State-aggregated Neuroticism scores were based on 1999-2005 responses of 619,397 residents to the 44-item Big Five Inventory. State Republican-Democrat preference was based on the 2002 occupancy of the U.S. Presidency, U.S. House, U.S. Senate, state House, state Senate, and state Governorship, as well as state-aggregated partisanship responses of 110,305 persons to 1998-2002 CBS/New York Times national polls. State conservative-liberal ideological orientation was based on 1998-2002 state-aggregated responses of 103,828 persons to CBS/New York Times national polls. Using correlation, partial correlation, and hierarchical multiple regression, it was determined that lower state resident Neuroticism is associated with Republican preference, and that both conservative-liberal ideological orientation and state resident Neuroticism account independently for variance in Republican-Democrat preference. These relations were found when 1998-2002 state socioeconomic status, white percent, and urban percent were statistically considered and controlled in partial correlation and hierarchical regression analysis. In contrast, corresponding analyses involving the other Big Five showed that only Openness and Conscientiousness showed any relation to partisanship, albeit infrequent and inconsistent. State resident Neuroticism is the primary state-level Big Five predictor of Republican/Democratic Party choice.

    2013-08-01

    The term "Service robotics" describes semi- or fully autonomous technical systems able to perform services useful to the well-being of humans. Service robots have the potential to support and disburden both persons in need of care as well as nursing care staff. In addition, they can be used in prevention and rehabilitation in order to reduce or avoid the need for help. Products currently available to support people in domestic environments are mainly cleaning or remote-controlled communication robots. Examples of current research activities are the (further) development of mobile robots as advanced communication assistants or the development of (semi) autonomous manipulation aids and multifunctional household assistants. Transport robots are commonly used in many hospitals. In nursing care facilities, the first evaluations have already been made. So-called emotional robots are now sold as products and can be used for therapeutic, occupational, or entertainment activities.

    We studied the functionality of the antioxidant system in laboratory rat cardiomyocytes and blood under psychoemotional stress.It was found that 40-day isolation and violation of diurnal cycle among the animals were accompanied by the intensification of lipid peroxidation process and marked with a reduced activity of antioxidant system enzymes, such as catalase and superoxide dismutase activity.The results suggested that psycho-emotional stress was accompanied by oxidative stress, causing a reduction in the intensity of energy metabolism in cardiomyocytes, which was further strengthened by the fact that the activity of the enzymes involved in ATP synthesis in mitochondria was reduced.Based on the results, we proposed that psychological stress is one of the factors contributing to the development of various cardiac diseases.

  3. Charge Neutral Fermionic States and Current Oscillation in a Graphene-Superconductor Hybrid Structure

    2016-10-01

    The proximity properties of edge currents in the vicinity of the interface between the graphene and superconductor in the presence of magnetic field are investigated. It is shown that the edge states introduced by Andreev reflection at the graphene-superconductor (G/S) interface give rise to the charge neutral states in all Landau levels. We note that in a topological insulator-superconductor (TI/S) hybrid structure, only N = 0 Landau level can support this type of charge neutral states. The different interface states of a G/S hybrid and a TI/S hybrid is due to that graphene consists of two distinct sublattices. The armchair edge consists of two inequivalent atoms. This gives rise to unique electronic properties of edge states when connected to a superconductor. A direct consequence of zero charge states in all Landau levels is that the current density approaches zero at interface. The proximity effect leads to quantum magnetic oscillation of the current density in the superconductor region. The interface current density can also be tuned with a finite interface potential. For sharp δ-type interface potential, the derivative of the wavefunction is discontinuous. As a result, we found that there is current density discontinuity at the interface. The step of the current discontinuity is proportional to the strength of the interface potential.

    Lane, Andrew M; Wilson, Mathew

    2011-07-01

    The aim of this study was to investigate relationships between trait emotional intelligence and emotional state changes over the course of an ultra-endurance foot race covering a route of approximately 175 miles (282 km) and held in set stages over six days. A repeated measures field design that sought to maintain ecological validity was used. Trait emotional intelligence was defined as a relatively stable concept that should predict adaptive emotional states experienced over the duration of the race and therefore associate with pleasant emotions during a 6-stage endurance event. Thirty-four runners completed a self-report measure of trait emotional intelligence before the event started. Participants reported emotional states before and after each of the six races. Repeated measures ANOVA results showed significant variations in emotions over time and a main effect for trait emotional intelligence. Runners high in self-report trait emotional intelligence also reported higher pleasant and lower unpleasant emotions than runners low in trait emotional intelligence. Findings lend support to the notion that trait emotional intelligence associates with adaptive psychological states, suggesting that it may be a key individual difference that explains why some athletes respond to repeated bouts of hard exercise better than others. Future research should test the effectiveness of interventions designed to enhance trait emotional intelligence and examine the attendant impact on emotional responses to intense exercise during multi-stage events.

Therefore, the purpose of the present study was the comparison of attentional bias and difficulty of emotional states regulation and their correlation with craving severity in drug abuser methamphetamines and crack. Materials and Methods: Type of research was descriptive analytical correlation. Population was total of users with methamphetamines and crack in summer and fall 2011 at the city of Isfahan, and 34 users with crystal with daily at least one year were selected on the basis of the snow ball sampling and 31 users with crack with daily at least one year were selected on the basis of the sample sampling. The difficulties emotion regulation scale (DERS, Stroop test and OCDUS were used as the outcome measures. For findings used of descriptive statistics and multivariate analysis of covariance (MANCOVA and regression analysis were used. Results: The results of analysis of variance showed that between drug abuser crystal and crack significantly differed of attentional bias and difficulty of emotional states regulation. The greatest differences to components of a lack of transparency, lack of emotional awareness, limit emotional states regulation strategies and of emotional responses. But, only the variable non-acceptance negative emotional of subscale of the difficulty of emotional states regulation was able to craving (as an important indicator of durable use substance in of both crack and crystal predicted. This variable is only 13% of the variance craving in drug abuser crack and crystal can be explained. Other findings showed that although there is no difference between the two groups in the intensity of craving, but attentional bias among drug abuser crack and crystal was a significant difference. Conclusion: Overall, can be said

    A steady-state, fully noninductive plasma current has been sustained for the first time in a tokamak using electron cyclotron current drive only. In this discharge, 123 kA of current have been sustained for the entire gyrotron pulse duration of 2 s. Careful distribution across the plasma minor radius of the power deposited from three 0.5-MW gyrotrons was essential for reaching steady-state conditions. With central current drive, up to 153 kA of current have been fully replaced transiently for 100 ms. The noninductive scenario is confirmed by the ability to recharge the Ohmic transformer. The dependence of the current drive efficiency on the minor radius is also demonstrated.

    Four-terminal resistance measurements have been carried out on Zn nanowires formed using electron-beam lithography. When driven resistive by current, these wires reenter the superconducting state upon application of small magnetic fields. The data are qualitatively different from those of previous experiments on superconducting nanowires, which revealed either negative magnetoresistance near T_{c} or high-magnetic-field-enhanced critical currents.

    Child maltreatment is a public health concern with well-established sequelae. However, compared to research on physical and sexual abuse, far less is known about the long-term impact of emotional maltreatment on mental health. The overall purpose of this study was to examine the association of emotional abuse, emotional neglect, and both emotional abuse and neglect with other types of child maltreatment, a family history of dysfunction, and lifetime diagnoses of several Axis I and Axis II mental disorders. Data were from the National Epidemiological Survey on Alcohol and Related Conditions collected in 2004 and 2005 (n=34,653). The most prevalent form of emotional maltreatment was emotional neglect only (6.2%), followed by emotional abuse only (4.8%), and then both emotional abuse and neglect (3.1%). All categories of emotional maltreatment were strongly related to other forms of child maltreatment (odds ratios [ORs] ranged from 2.1 to 68.0) and a history of family dysfunction (ORs ranged from 2.2 to 8.3). In models adjusting for sociodemographic characteristics, all categories of emotional maltreatment were associated with increased odds of almost every mental disorder assessed in this study (adjusted ORs ranged from 1.2 to 7.4). Many relationships remained significant independent of experiencing other forms of child maltreatment and a family history of dysfunction (adjusted ORs ranged from 1.2 to 3.0). The effects appeared to be greater for active (i.e., emotional abuse) relative to passive (i.e., emotional neglect) forms of emotional maltreatment. Childhood emotional maltreatment, particularly emotionally abusive acts, is associated with increased odds of lifetime diagnoses of several Axis I and Axis II mental disorders.

    Increasing energy consumption and depleting reserves of fossil fuels have resulted in growing interest in alternative renewable energy from the ocean. Ocean currents are an alternative source of clean energy due to their inherent reliability, persistence and sustainability. General ocean circulations exist in the form of large rotating ocean gyres, and feature extremely rapid current flow in the western boundaries due to the Coriolis Effect. The Gulf Stream system is formed by the western boundary current of the North Atlantic Ocean that flows along the east coastline of the United States, and therefore is of particular interest as a potential energy resource for the United States.

    Full Text Available The insular cortex has been considered to be the neural base of visceral sensation for many years. Previous studies in psychology and cognitive neuroscience have accumulated evidence indicating that interoception is an essential factor in the subjective feeling of emotion. Recent neuroimaging studies have demonstrated that anterior insular cortex activation is associated with accessing interoceptive information and underpinning the subjective experience of emotional state.Only a small number of studies have focused on the influence of insular damage on emotion processing and interoceptive awareness. Moreover, disparate hypotheses have been proposed for the alteration of emotion processing by insular lesions. Some studies show that insular lesions yield an inability for understanding and representing disgust exclusively, but other studies suggest that such lesions modulate arousal and valence judgments for both positive and negative emotions.In this study, we examined the alteration in emotion recognition in three right insular and adjacent area damaged cases with well-preserved higher cognitive function. Participants performed an experimental task using morphed photos that ranged between neutral and emotional facial expressions (i.e., anger, sadness, disgust, and happiness. Recognition rates of particular emotions were calculated to measure emotional sensitivity. In addition, they performed heartbeat perception task for measuring interoceptive accuracy. The cases identified emotions that have high arousal level (e.g., anger as less aroused emotions (e.g., sadness and a case showed remarkably low interoceptive accuracy. The current results show that insular lesions lead to attenuated emotional sensitivity across emotions, rather than category-specific impairments such as to disgust. Despite the small number of cases, our findings suggest that the insular cortex modulates recognition of emotional saliency and mediates interoceptive and emotional

    The State Space modelling approach has been recently proposed as an engineering-driven technique for part quality prediction in Multistage Machining Processes (MMP). Current State Space models incorporate fixture and datum variations in the multi-stage variation propagation, without explicitly considering common operation variations such as machine-tool thermal distortions, cutting-tool wear, cutting-tool deflections, etc. This paper shows the limitations of the current State Space model through an experimental case study where the effect of the spindle thermal expansion, cutting-tool flank wear and locator errors are introduced. The paper also discusses the extension of the current State Space model to include operation variations and its potential benefits.

  15. High ion charge states in a high-current, short-pulse, vacuum ARC ion sources

    Ions of the cathode material are formed at vacuum arc cathode spots and extracted by a grid system. The ion charge states (typically 1-4) depend on the cathode material and only little on the discharge current as long as the current is low. Here the authors report on experiments with short pulses (several {mu}s) and high currents (several kA); this regime of operation is thus approaching a more vacuum spark-like regime. Mean ion charge states of up to 6.2 for tungsten and 3.7 for titanium have been measured, with the corresponding maximum charge states of up to 8+ and 6+, respectively. The results are discussed in terms of Saha calculations and freezing of the charge state distribution.

    We propose a novel series transformer based diode-bridge-type solid state fault current limiter (SSFCL). To control the fault current, a series RLC branch is connected to the secondary side of an isolation series transformer. Based on this RLC branch, two current limiting modes are created. In the first mode, R and C are bypassed via a paralleled power electronic switch (insulated-gate bipolar transistor, IGBT) and L remains connected to the secondary side of the transformer as a DC reactor. In the second mode, the series reactor impedance is not enough to limit the fault current. In this case, the fault current can be con-trolled by selecting a proper on-off duration of the parallel IGBT, across the series damping resistor (R) and capacitor, which inserts high impedance into the line to limit the fault current. Then, by controlling the magnitude of the DC reactor current, the fault current is reduced and the voltage of the point of common coupling (PCC) is kept at an acceptable level. In addition, in the new SSFCL, the series RC branch, connected in parallel with the IGBT, serves as a snubber circuit for decreasing the transient recovery voltage (TRV) of the IGBT during on-off states. Therefore, the power quality indices can be improved. The measure-ment results of a built prototype are presented to support the simulation and theoretical studies. The proposed SSFCL can limit the fault current without any delay and successfully smooth the fault current waveform.

    2015-01-01

    Implicit emotion regulation is an important form of emotion regulation. It is a process aimed at modifying the quality, intensity, or duration of an emotional response without the need for conscious supervision or explicit intentions. The underlying psychological mechanism of implicit emotion regulation is automatic counter-regulation, which produces balance in affective processing and thus protects the self against escalating affective and motivational states. Experimental studies of counter-regulation typically comprise of two successive steps, which are (1) inducing a particular emotion (positive vs. negative), (2) establishing an implicit counter-regulation process. Implicit emotion regulation mainly activates the anterior cingulate cortex, ventrolateral prefrontal cortex and ventral medial prefrontal cortex. The main forms of implicit emotion regulation are implicit cognitive reappraisal, affect labeling and habitual practice. The efficiency of implicit emotion regulation is also affected by individual differences (e.g., action vs. state orientation, psychopathology), and by the intensity of emotional experience (automatic counter-regulation is stronger for intense emotions).%内隐情绪调节是情绪调节的一种重要形式, 它是指个体在没有意识监控和意图的情况下改变了自身情绪反应的品质、强度和持续时间等的一种情绪活动过程.内隐情绪调节的内部机制是自动反向调节, 它能让个体的情绪保持平衡状态, 具有自我保护作用; 其实验研究过程一般分为诱导特定情绪、引发内隐调节过程两个步骤.内隐情绪调节涉及的脑区主要有前扣带回皮层、腹外侧前额叶皮层和腹内侧前额叶皮层.内隐情绪调节的形式包括内隐认知重评和情绪标签等, 这些调节方式本身可能受个体差异、情绪体验强度等多种因素的影响.

    Dried-bonito broth (DBB, katsuo-bushi dashi) is commonly used in Japanese cuisine, and is also used as a traditional remedy for recovery from fatigue and improvement of blood circulation. To clarify the effect of DBB on blood pressure, oxidative stress and emotional states, a randomized crossover human trial was performed. Twenty-seven elderly Japanese subjects ingested DBB or water for one month. Measurement of blood pressure and urinary 8-hydroxydeoxyguanosine (8-OHdG) and evaluation of emotional states were performed before and after the ingestion periods. The changes in systolic blood pressure (SBP) during DBB ingestion was significantly lower than that during water ingestion (p = 0.037). Urinary 8-OHdG significantly decreased during DBB ingestion (p = 0.0002). Evaluation of emotional states indicated that composure significantly improved during DBB ingestion (p = 0.034). These results suggest that the daily ingestion of DBB lower SBP, reduce urinary 8-OHdG and might improve emotional states in elderly subjects.

    Klee, R; Heinemann, U; Eder, C

    1999-01-01

    Whole-cell patch-clamp measurements were performed to investigate voltage-gated proton currents (I(PR)) in cultured murine microglia of distinct morphology and functional state. We studied I(PR) in ameboid microglia of untreated cultures, in ameboid microglia which had been activated by lipopolysaccharide, and in ramified microglia which had been exposed to astrocyte-conditioned medium. Proton currents of these three microglia populations did not differ regarding their activation threshold or the voltage dependence of steady-state activation. Moreover, pharmacological properties of I(PR) were similar: proton currents were sensitive to extracellularly applied Zn2+ or La3+, and could be abolished by each of those at a concentration of 100 microM. In the presence of extracellular Na+, I(PR) was decreased to a similar small extent due to activity of the Na+/H+ exchanger in all microglial populations. In contrast, proton currents of microglia differed between the three cell populations with respect to their current density and their time-course of activation: in comparison with untreated microglia, the current density of I(PR) was reduced by about 50% in microglia after their treatment with either lipopolysaccharide or astrocyte-conditioned medium. Moreover, I(PR) activated significantly more slowly in cells exposed to lipopolysaccharide or astrocyte-conditioned medium than in untreated cells. It can be concluded that the distinct H+ current characteristics of the three microglial populations do not correlate with the functional state of the cells.

    Gaelle eDesbordes

    2012-11-01

    Full Text Available The amygdala has been repeatedly implicated in emotional processing of both positive and negative valence stimuli. Previous studies suggest that the amygdala response to emotional stimuli is lower when the subject is in a meditative state of mindful attention, both in beginner meditators after an eight-week meditation intervention and in expert meditators. However, the longitudinal effects of meditation training on amygdala responses have not been reported when participants are in an ordinary, non-meditative state. In this study, we investigated how eight weeks of training in meditation affects amygdala responses to emotional stimuli in subjects when in a non-meditative state. Healthy adults with no prior meditation experience took part in eight weeks of either Mindful Attention Training, Cognitively-Based Compassion Training (CBCT; a program based on Tibetan Buddhist compassion meditation practices, or an active control intervention. Before and after the intervention, participants underwent an fMRI experiment during which they were presented images with positive, negative, and neutral emotional valences from the IAPS database while remaining in an ordinary, non-meditative state. Using a region-of-interest analysis, we found a longitudinal decrease in right amygdala activation in the Mindful Attention group in response to positive images, and in response to images of all valences overall. In the CBCT group, we found a trend increase in right amygdala response to negative images, which was significantly correlated with a decrease in depression score. No effects or trends were observed in the control group. This finding suggests that the effects of meditation training on emotional processing might transfer to non-meditative states. This is consistent with the hypothesis that meditation training may induce learning that is not stimulus- or task-specific, but process-specific, and thereby may result in enduring changes in mental function.

    2017-03-01

    In the phase-change memory (PCM) crystallization occurs in the high-current filament which forms during switching to the conductive state. In the present paper we conduct a numerical modeling of the current filament formation dynamics in thin chalcogenide films using an electronic-thermal model based on negative-U centers tunnel ionization and Joule heating. The key role of inhomogeneities in the filament formation process is shown. Steady-state filament parameters were obtained from the analysis of the stationary heat conduction equation. The filament formation dynamics and the steady-state filament radius and temperature could be controlled by material parameters and contact resistance. Consequently it is possible to control the size of the region wherein crystallization occurs. A good agreement with numerous experimental data leads to the conclusion that thermal effects play a significant role in CGS conduction and high-current filament formation while switching.

  14. Including Alternative Resources in State Renewable Portfolio Standards: Current Design and Implementation Experience

    Heeter, J.; Bird, L.

    2012-11-01

    Currently, 29 states, the District of Columbia, and Puerto Rico have instituted a renewable portfolio standard (RPS). An RPS sets a minimum threshold for how much renewable energy must be generated in a given year. Each state policy is unique, varying in percentage targets, timetables, and eligible resources. This paper examines state experience with implementing renewable portfolio standards that include energy efficiency, thermal resources, and non-renewable energy and explores compliance experience, costs, and how states evaluate, measure, and verify energy efficiency and convert thermal energy. It aims to gain insights from the experience of states for possible federal clean energy policy as well as to share experience and lessons for state RPS implementation.

    2017-09-01

    Recently, a number of quantum theory (QT)-based information retrieval (IR) models have been proposed for modeling session search task that users issue queries continuously in order to describe their evolving information needs (IN). However, the standard formalism of QT cannot provide a complete description for users' current IN in a sense that it does not take the 'future' information into consideration. Therefore, to seek a more proper and complete representation for users' IN, we construct a representation of quasi-current IN inspired by an emerging Two-State Vector Formalism (TSVF). With the enlightenment of the completeness of TSVF, a ;two-state vector; derived from the 'future' (the current query) and the 'history' (the previous query) is employed to describe users' quasi-current IN in a more complete way. Extensive experiments are conducted on the session tracks of TREC 2013 & 2014, and show that our model outperforms a series of compared IR models.

    2012-04-01

    Emotional inertia refers to the degree to which a person's current emotional state is predicted by their prior emotional state, reflecting how much it carries over from one moment to the next. Recently, in a cross-sectional study, we showed that high inertia is an important characteristic of the emotion dynamics observed in psychological maladjustment such as depression. In the present study, we examined whether emotional inertia prospectively predicts the onset of first-episode depression during adolescence. Emotional inertia was assessed in a sample of early adolescents (N = 165) based on second-to-second behavioral coding of videotaped naturalistic interactions with a parent. Greater inertia of both negative and positive emotional behaviors predicted the emergence of clinical depression 2.5 years later. The implications of these findings for the understanding of the etiology and early detection of depression are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    A systematic study of irreversible magnetization was performed in bulk niobium after different surface treatments. Starting with smooth surfaces and abrading them, a strong increase of the critical current is observed up to an apparent limiting value. An impressive change of the critical current is also observed in the surface superconductivity (SSC) state, reaching values of the same order of magnitude as in the mixed state. We explain also the observation of strong SSC for magnetic fields perpendicular to large facets in terms of nucleation of superconductivity along bumps of a corrugated surface.

    2016-09-01

    Full Text Available The article analyses research data and scholarly approaches to the study: of problems of parents arising from their child’s illness; the emotional states of parents raising a child with developmental disabilities; stages of emotional experience related to the birth of a sick child. The family as an integral unit has to face various situations determined by the social impact of the child’s disease or impairment, as well as emotional and psychological reactions of the parents to it. Being aware of the psychological stages singled out in the grief theory helps professionals: to understand the reaction of the family of a child with developmental disabilities; realise when and how it is best to intervene, flexibly apply the theory of stages, and account for the specific characteristics of a particular family and individual reactions to such shocks.

    In the context of inclusive education, so-called «Schulbegleiter» (school escorts) have been installed to assist children with special needs. However, adequate conceptions of their role are lacking, and no provisions exist describing the exact tasks and duties of these school escorts. This article presents data on a statewide empirical study and provides information on the professional background, qualifications, and assignments of such escorts as well as the nature of the assisted children in the German state of Baden-Württemberg. The data were collected in nearly 50 % of all schools providing general education in Baden-Württemberg, and a total of 526 school escorts completed a questionnaire on their work. Children with special needs who received such assistance were aged 6 to 19 years (M = 10.4) and had a mental disorder in nearly three-fourths of all cases, with autism spectrum disorders being most common (59.4 %). The most frequent assignments of the escorts were providing practical assistance during classes and mobilizing the child as well as providing direct support in emotionally challenging situations. Such escorts can make a significant contribution to the inclusive education of disabled children. They do, however, need an adequate qualification and practical competences to meet the diverse challenges of children with special needs. Child and adolescent psychiatrists are supposed to stay involved in the process, not only by planning interventions, but also during the course of inclusive education itself. Thus, the emotional situation and adjustment of included children with mental disorders over time must be monitored adequately.

    Full Text Available Previous neuroscientific studies have shown that the dopaminergic system plays an important role in creativity potential measured by divergent thinking (CPMDT, emotional control, and motivational state. However, although associations between two of these four components have been previously established (e.g., the association between CPMDT and emotional control, the association between CPMDT and motivational state, etc., the interactions between these four remain unknown. The purpose of this study was to reveal these interactions using path analyses. The Taq1A polymorphism of the dopamine D2 receptor (DRD2 gene was used for this purpose. For measuring emotional intelligence (EI, we used the Japanese version of the Emotional Intelligence Scale. CPMDT was measured using the S-A creativity test. Motivational state was measured using the Vigor subscale of the Japanese version of the Profile of Mood Scale (POMS. Data from 766 healthy, right-handed individuals (426 men and 340 women; 20.7 ± 1.9 years of age were used in this study. There were significant and robust positive relationships among measures of CPMDT, EI, and motivational state across sex. In addition, the polymorphism of the DRD2 gene was significantly associated with EI, specifically in females. Path analysis in females indicates that the model in which (a the DRD2 polymorphism primarily facilitates EI, (b EI in turn facilitates CPMDT and leads to a better motivational state, and (c a better motivational state also directly facilitates CPMDT explains the data in the most accurate manner. This study suggested a comprehensive picture of the cascade of the associations among dopamine, EI, motivational state, and CPMDT at least in females.

    Full Text Available The purpose of this review is to summarize and evaluate the current state of the literature with regards to attachment and its relationship to emotion in middle childhood and adolescence. This is a relatively new topic of interest and one which is well grounded in theory. The attachment relationship between parents and children is a key mechanism by which children and adolescents learn emotion skills, including emotion understanding, coping strategies, and how to manage different affective experiences. The review is organized by emotion domain, including emotion understanding, affective experiences, physiological indicators of arousal and emotion, and processes for the regulation of emotion. We included studies which presented data for children and adolescents ages 6-18, and included measures of emotion and parent-child attachment. Although some areas have been investigated more than others, we found that secure attachment was related to more adaptive functioning in each of the emotion domains. Finally, we review future directions to be explored and address gaps in the current literature.

    Full Text Available Social and psychological stressors are both a part of daily life and are increasingly recognized as contributors to individual susceptibility to develop diseases and metabolic disorders. The present study investigated how snacks differing in sensory properties and presentation can influence ratings of affect in consumers with different levels of dispositional anxiety. This study examines the relationships between a pre-disposition to anxiety and food using a repeated exposures design with three interspersed test days over a period of two weeks. The study was conducted on ninety free-living male (n = 28 and female (n = 62 Dutch participants aged between 18 and 35 years old, with a BMI between 18 and 25 kg/m2 and different anxiety trait levels assessed using State-Trait Anxiety Inventory tests. The study was randomized by age, gender, anxiety trait score, and followed a parallel open design. Three test products: dark chocolate, a milk chocolate snack and crackers with cheese spread (control, which differed in composition, sensory properties and presentation, were evaluated. Changes in self-reported anxiety, emotion, and energetic states were assessed as a function of eating the snacks just after consumption and up to one hour. The repeated exposure design over a period of two weeks enabled the investigations of potential cumulative effects of regular consumption of the food products. The milk chocolate snack resulted in the decrease of anxiety in high anxiety trait subjects, whereas dark chocolate and cheese and crackers respectively improved the anxiety level and the energetic state of low anxiety trait participants. The mood effects were not altered with repeated exposure, and the magnitude of changes was similar on each test day, which illustrates the repeatability of the effects of the food on subjective measures of postprandial wellness.

    An active filter that uses a high-frequency D-class asynchronous switching inverter for power system current distortion compensation is described. The distortion compensation technique involves deriving a signal corresponding to the distortion component of load current, and inverting and amplifying this signal for addition back to the supply current to cancel the load current distortion. A synthetic sinusoid is used to determine the distortion component in the time domain. Extensive computed and experimental results, illustrating the system's steady-state performance and ability to reduce the current harmonic distortion components, are presented. An intelligent controller is proposed to maintain the active filter's performance at the optimal operating point under varying load conditions.

    We study the spectral characteristics of spin current nano-oscillators based on the Pt/[Co/Ni] magnetic multilayer with perpendicular magnetic anisotropy. By varying the applied magnetic field and current, both localized and propagating spin wave modes of the oscillation are achieved. At small fields, we observe an abrupt onset of the modulation sidebands. We use micromagnetic simulations to identify this state as a dynamical magnetic skyrmion stabilized in the active device region by spin current injection, whose current-induced dynamics is accompanied by the gyrotropic motion of the core due to the skew deflection. Our results demonstrate a practical route for controllable skyrmion manipulation by spin current in magnetic thin films.

    In order to compensate for lack of emotion communication between teachers and students in e-learning systems, we have designed and implemented the EmotionChat -- a web chatroom with emotion regulation. EmotionChat perceives e-learners' emotional states based on interactive text. And it recommends resources such as music, cartoons, and mottos to an e-learner when it detects negative emotional states. Meanwhile, it recommends emotion regulation cases to the e-learner's listeners and teachers. The result of our initial experiment shows that EmotionChat can recommend valuable emotion regulation policies for e-learners.

  13. Beliefs about emotions as a metacognitive construct: initial development of a self-report questionnaire measure and preliminary investigation in relation to emotion regulation.

    Science.gov (United States)

    Manser, Rachel; Cooper, Myra; Trefusis, Jo

    2012-01-01

    Metacognitive theory, amongst other theories, gives an important role to beliefs about mental states, including beliefs about emotions, in the maintenance of distress. Mentalization theory as well as the dialectical behaviour therapy and emotion-focused therapy literature specifies particular beliefs thought to be related to emotion dysregulation and therefore to a label of borderline personality disorder. The current study aimed to develop a questionnaire to measure the beliefs about emotions as specified by this literature and to test the relationship of this new measure to various aspects of emotion regulation in a non-clinical sample of 289 participants. A factor analysis extracted six factors, which described beliefs about emotions as (a) overwhelming and uncontrollable; (b) shameful and irrational; (c) invalid and meaningless; (d) useless; (e) damaging; and (f) contagious. The final measure showed some promising psychometric properties. All of the questionnaire subscales were related to aspects of emotion dysregulation including distress, borderline personality disorder symptoms and behaviours associated with dysregulation of emotion, suggesting that beliefs about emotions could be an important metacognitive construct involved in the ability to regulate emotions. Beliefs about emotions may be a useful direct or indirect target for treatment of difficulties regulating emotions, and this could be achieved through the use of various therapeutic modalities.

    The aim of the study was to evaluate associations of emotional state and quality of life with lipid concentration, duration of the disease, and the way of treating the disease in males and females with type 2 diabetes mellitus. A total of 53 persons with type 2 diabetes mellitus (27 males and 26 females; mean age, 58.7+/-8.9 years) and 56 healthy persons (26 males and 30 females; mean age, 54.7+/-8.3 years) participated in the study. Emotional state was evaluated by means of Profile of Mood State and quality of life by means of WHO Brief Quality of Life Questionnaire. Emotional state and quality of life were significantly worse, tension-anxiety and fatigue-inertia were significantly higher, vigor-activity was significantly lower in male patients with type 2 diabetes mellitus than in healthy males. In females, no significant differences in emotional state and quality of life comparing type 2 diabetes mellitus group and controls were detected. In females with type 2 diabetes mellitus, emotional state and quality of life were significantly better, scores of tension-anxiety, depression dejection, anger-hostility, and fatigue-inertia were significantly lower, and score of vigor-activity was significantly higher than in males with type 2 diabetes mellitus. Some significant correlations were found. In males, vigor-activity correlated with total cholesterol level and negatively correlated with triglyceride level. In females, significant correlations were found between scores of emotional state (tension-anxiety, depression-dejection, confusion-bewilderment, and total score of emotional state) and lipid levels (total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels). There were no significant associations of emotional state and quality of life with duration of the disease in males and females with type 2 diabetes mellitus. No significant differences in emotional state and quality of life were found between males and females with type 2 diabetes

  16. On the Role of Crossmodal Prediction in Audiovisual Emotion Perception

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available Humans rely on multiple sensory modalities to determine the emotional state of others. In fact, such multisensory perception may be one of the mechanisms explaining the ease and efficiency by which others’ emotions are recognized. But how and when exactly do the different modalities interact? One aspect in multisensory perception that has received increasing interest in recent years is the concept of crossmodal prediction. In emotion perception, as in most other settings, visual information precedes the auditory one. Thereby, leading in visual information can facilitate subsequent auditory processing. While this mechanism has often been described in audiovisual speech perception, it has not been addressed so far in audiovisual emotion perception. Based on the current state of the art in (a crossmodal prediction and (b multisensory emotion perception research, we propose that it is essential to consider the former in order to fully understand the latter. Focusing on electroencephalographic (EEG and magnetoencephalographic (MEG studies, we provide a brief overview of the current research in both fields. In discussing these findings, we suggest that emotional visual information may allow for a more reliable prediction of auditory information compared to non-emotional visual information. In support of this hypothesis, we present a re-analysis of a previous data set that shows an inverse correlation between the N1 response in the EEG and the duration of visual emotional but not non-emotional information. If the assumption that emotional content allows for more reliable predictions can be corroborated in future studies, crossmodal prediction is a crucial factor in our understanding of multisensory emotion perception.

    Prognostics is the process of predicting a system's future states, health degradation/wear, and remaining useful life (RUL). This information plays an important role in preventing failure, reducing downtime, scheduling maintenance, and improving system utility. Prognostics relies heavily on wear estimation. In some components, the sensors used to estimate wear may not be fast enough to capture brief transient states that are indicative of wear. For this reason it is beneficial to be capable of detecting and estimating the extent of component wear using steady-state measurements. This paper details a method for estimating component wear using steady-state measurements, describes how this is used to predict future states, and presents a case study of a current/pressure (I/P) Transducer. I/P Transducer nominal and off-nominal behaviors are characterized using a physics-based model, and validated against expected and observed component behavior. This model is used to map observed steady-state responses to corresponding fault parameter values in the form of a lookup table. This method was chosen because of its fast, efficient nature, and its ability to be applied to both linear and non-linear systems. Using measurements of the steady state output, and the lookup table, wear is estimated. A regression is used to estimate the wear propagation parameter and characterize the damage progression function, which are used to predict future states and the remaining useful life of the system.

    The study of emotional signaling has focused almost exclusively on the face and voice. In 2 studies, the authors investigated whether people can identify emotions from the experience of being touched by a stranger on the arm (without seeing the touch). In the 3rd study, they investigated whether observers can identify emotions from watching someone being touched on the arm. Two kinds of evidence suggest that humans can communicate numerous emotions with touch. First, participants in the United States (Study 1) and Spain (Study 2) could decode anger, fear, disgust, love, gratitude, and sympathy via touch at much-better-than-chance levels. Second, fine-grained coding documented specific touch behaviors associated with different emotions. In Study 3, the authors provide evidence that participants can accurately decode distinct emotions by merely watching others communicate via touch. The findings are discussed in terms of their contributions to affective science and the evolution of altruism and cooperation. (c) 2006 APA, all rights reserved

  20. Interpreting current-induced spin polarization in topological insulator surface states

    Li, Pengke; Appelbaum, Ian

    2016-06-01

    Several recent experiments on three-dimensional topological insulators claim to observe a large charge current-induced nonequilibrium ensemble spin polarization of electrons in the helical surface state. We present a comprehensive criticism of such claims, using both theory and experiment: First, we clarify the interpretation of quantities extracted from these measurements by deriving standard expressions from a Boltzmann transport equation approach in the relaxation-time approximation at zero and finite temperature to emphasize our assertion that, despite high in-plane spin projection, obtainable current-induced ensemble spin polarization is minuscule. Second, we use a simple experiment to demonstrate that magnetic field-dependent open-circuit voltage hysteresis (identical to those attributed to current-induced spin polarization in topological insulator surface states) can be generated in analogous devices where current is driven through thin films of a topologically trivial metal. This result ipso facto discredits the naive interpretation of previous experiments with TIs, which were used to claim observation of helicity, i.e., spin-momentum locking in the topologically protected surface state.

  1. Lower bounds for ballistic current and noise in non-equilibrium quantum steady states

    Full Text Available Let an infinite, homogeneous, many-body quantum system be unitarily evolved for a long time from a state where two halves are independently thermalized. One says that a non-equilibrium steady state emerges if there are nonzero steady currents in the central region. In particular, their presence is a signature of ballistic transport. We analyze the consequences of the current observable being a conserved density; near equilibrium this is known to give rise to linear wave propagation and a nonzero Drude peak. Using the Lieb–Robinson bound, we derive, under a certain regularity condition, a lower bound for the non-equilibrium steady-state current determined by equilibrium averages. This shows and quantifies the presence of ballistic transport far from equilibrium. The inequality suggests the definition of “nonlinear sound velocities”, which specialize to the sound velocity near equilibrium in non-integrable models, and “generalized sound velocities”, which encode generalized Gibbs thermalization in integrable models. These are bounded by the Lieb–Robinson velocity. The inequality also gives rise to a bound on the energy current noise in the case of pure energy transport. We show that the inequality is satisfied in many models where exact results are available, and that it is saturated at one-dimensional criticality.

    Point contacts between normal and ferromagnetic metals are investigated using magnetoresistance and transport spectroscopy measurements combined with micromagnetic simulations. Pronounced hysteresis in the point contact resistance versus both bias current and external magnetic field are observed. It is found that such hysteretic resistance can exhibit, in addition to bi-stable resistance states found in ordinary spin valves, tri-stable resistance states with a middle resistance level. We interpret these observations in terms of surface spin valve and spin vortex states, originating from a substantially modified spin structure at the ferromagnetic interface in the contact core. We argue that these surface spin states, subject to a weakened exchange interaction, dominate the effects of spin transfer torques on the nanometer scale.

    2015-08-01

    Full Text Available This article discusses the results of a study of actual mental state of high school students who are active subjects of career self-determination in terms of interactive learning. There are four groups of methods of interactive training: psychological training, art therapy, cognitive, and game training. The main task, which is solved by a researcher in a formative experiment with the use of each of these methods, is to establish significant differences in health, activity and mood as the indicators of current mental state of students in the classroom. As a result, we found that the most significant improvements in the current mental state takes place when using art and game therapy, so these techniques should be used in groups of students with low motivation to work, as well as in the adverse psychological climate. Less significant was the improvement of the current mental state after psychological training due to the fact that this method allow to update and seek solutions to the most important intrapersonal issues and require the implementation of a deeper reflection

    The current study examined associations between maternal posttraumatic stress disorder (PTSD) symptoms and infant emotional reactivity and emotion regulation during the first year of life in a primarily low-income, urban, ethnic/racial minority sample of 52 mother-infant dyads. Mothers completed questionnaires assessing their own trauma exposure history and current PTSD and depressive symptoms and their infants’ temperament when the infants were 6 months old. Dyads participated in the repeated Still-Face Paradigm (SFP-R) when the infants were 6 months old, and infant affective states were coded for each SFP-R episode. Mothers completed questionnaires assessing infant trauma exposure history and infant current emotional and behavioral symptoms when the infants were 13 months old. Maternal PTSD symptoms predicted infants’ emotion regulation at 6 months as assessed by (a) infant ability to recover from distress during the SFP-R and (b) maternal report of infant rate of recovery from distress/arousal in daily life. Maternal PTSD symptoms also predicted maternal report of infant externalizing, internalizing, and dysregulation symptoms at 13 months. Maternal PTSD was not associated with measures of infant emotional reactivity. Neither maternal depressive symptoms nor infant direct exposure to trauma accounted for the associations between maternal PTSD symptoms and infant outcomes. These findings suggest that maternal PTSD is associated with offspring emotion regulation difficulties as early as infancy. Such difficulties may contribute to increased risk of mental health problems among children of mothers with PTSD. PMID:21862136

  7. Being deluded after being excluded? How emotion regulation deficits in paranoia-prone individuals affect state paranoia during experimentally induced social stress.

    Emotion regulation (ER) has become a relevant construct to understanding paranoia. While the ER strategy called expressive suppression (e.g., poker face) may foster state paranoia by increasing arousal, another strategy called reappraisal (e.g., changing the perspective on situations) may reduce negative emotions and state paranoia when adaptively used. However, if reappraisal fails, this could increase paranoia. The aim of this study was to test the proposed effects of the ER strategies on state paranoia in the socially stressful situation of being excluded in paranoia-prone individuals. We conducted an experimental online study with N=116 participants who were randomized to a social inclusion or an exclusion condition using a virtual Cyberball ball-tossing game. They completed questionnaires on paranoia proneness and habitual ER strategies. Before and after the Cyberball task, participants rated their level of state paranoia. The impact of habitual ER strategies, paranoia proneness, and social stress on changes in state paranoia was investigated using linear regression analysis. The three-way interaction of social stress, paranoia proneness, and habitual reappraisal use significantly predicted state paranoia, t(114)=2.62, p=0.010. The decomposition of the interaction term revealed that in the social stress condition, the impact of reappraisal on state paranoia was moderated by the level paranoia proneness. Specifically, in high paranoia-prone individuals the use of reappraisal predicted higher state paranoia. The findings regarding habitual use of suppression were not significant. Although reappraisal is generally considered a functional strategy, its use in distressing social situations seems to be impaired in persons with higher paranoia proneness. A working model of emotion dysregulation in delusions is presented and possible implications for cognitive therapy of psychosis are discussed.

    Rapid assessment of emotions is important for detecting and prioritizing salient input. Emotions are conveyed in spoken words via verbal and non-verbal channels that are mutually informative and unveil in parallel over time, but the neural dynamics and interactions of these processes are not well understood. In this paper, we review the literature on emotion perception in faces, written words, and voices, as a basis for understanding the functional organization of emotion perception in spoken words. The characteristics of visual and auditory routes to the amygdala—a subcortical center for emotion perception—are compared across these stimulus classes in terms of neural dynamics, hemispheric lateralization, and functionality. Converging results from neuroimaging, electrophysiological, and lesion studies suggest the existence of an afferent route to the amygdala and primary visual cortex for fast and subliminal processing of coarse emotional face cues. We suggest that a fast route to the amygdala may also function for brief non-verbal vocalizations (e.g., laugh, cry), in which emotional category is conveyed effectively by voice tone and intensity. However, emotional prosody which evolves on longer time scales and is conveyed by fine-grained spectral cues appears to be processed via a slower, indirect cortical route. For verbal emotional content, the bulk of current evidence, indicating predominant left lateralization of the amygdala response and timing of emotional effects attributable to speeded lexical access, is more consistent with an indirect cortical route to the amygdala. Top-down linguistic modulation may play an important role for prioritized perception of emotions in words. Understanding the neural dynamics and interactions of emotion and language perception is important for selecting potent stimuli and devising effective training and/or treatment approaches for the alleviation of emotional dysfunction across a range of neuropsychiatric states.

    The Mexican state of Tamaulipas located in the northeastern portion of the country currently has five state nature reserves covering slightly less than 3% of its land area. These reserves were established for a variety of reasons, many unrelated to the protection of biological resources. In 2000 in response to a growing concern about the lack of organized conservation reserve planning to protect the important biological and physical features of Mexico, the Mexican Commission for Knowledge and Use of Biodiversity (CONABIO) proposed 13 new terrestrial reserves for Tamaulipas. If established these new reserves would increase the proportion of terrestrial protected lands in the state to over 21%. We compiled a geographic information system (GIS) using existing digital thematic maps of physical and biological features to examine how the existing and proposed reserves might serve to protect the biodiversity and physical features of the state. We found that most of the existing protected sites occur in areas with elevations > 1000-2000 m with temperate climate and dominated by pine forest, oak forest, and cloud forest vegetation cover types. The state's dominant biotic region - low elevation coastal plain with tropical and arid climate types and xeric scrub vegetation - is disproportionately underrepresented in the current reserve system. The creation of the proposed areas would substantially increase the protection of mid and high elevation lands. The largest gap in the protected lands network would be low elevation, level, coastal lands.

    For modern nations, a healthy agricultural sector provides the necessary foundation for the economic growth and social progress that enhance their citizens′ quality of life.Historically, agriculture education has been a dynamic and growing facet of career and technical education in the United States. Currently, however, public policy and support for agriculture education is negatively impacted by a national attitude that devalues agriculture education and perceives it as less desirable than a four-year college degree. This paper considers the history, scope, and current status of agriculture education in the context of increasing worldwide demand for agricultural products and rapidly changing technology.

    Full Text Available This article summarizes the current state of meditation research, specifically focusing on mindfulness-based stress reduction and transcendental meditation. Despite significant methodological problems with the studies reported to date on the subject, there is consistent evidence that meditation can produce changes in the nervous system and physiology of the meditator, and can help with various psychological markers of well-being. Regarding improvement in specific clinical diseases, research is generally mixed and preliminary. Strong recommendations cannot be made based on current evidence, and further studies are needed. In general, there is a stronger body of evidence supporting mindfulness-based stress reduction than for transcendental meditation.

  13. Metacognition of emotional face recognition.

    2011-08-01

    While humans are adept at recognizing emotional states conveyed by facial expressions, the current literature suggests that they lack accurate metacognitions about their performance in this domain. This finding comes from global trait-based questionnaires that assess the extent to which an individual perceives him or herself as empathic, as compared to other people. Those who rate themselves as empathically accurate are no better than others at recognizing emotions. Metacognition of emotion recognition can also be assessed using relative measures that evaluate how well a person thinks s/he has understood the emotion in a particular facial display as compared to other displays. While this is the most common method of metacognitive assessment of people's judgments of learning or their feelings of knowing, this kind of metacognition--"relative meta-accuracy"--has not been studied within the domain of emotion. As well as asking for global metacognitive judgments, we asked people to provide relative, trial-by-trial prospective and retrospective judgments concerning whether they would be right or wrong in recognizing the expressions conveyed in particular facial displays. Our question was: Do people know when they will be correct in knowing what expression is conveyed, and do they know when they do not know? Although we, like others, found that global meta-accuracy was unpredictive of performance, relative meta-accuracy, given by the correlation between participants' trial-by-trial metacognitive judgments and performance on each item, were highly accurate both on the Mind in the Eyes task (Experiment 1) and on the Ekman Emotional Expression Multimorph task (in Experiment 2). 2011 APA, all rights reserved

    Full Text Available Among the many variables affecting happiness, there are those that arise from emotional factors. In this study, the hypothesis stating that happiness is affected by emotional self-efficacy, emotional empathy and emotional approach coping has been examined using the path model. A total of 334 university students participated in this study, 229 of whom were females and 105 being males. Oxford Happiness Questionnaire-Short Form, Emotional Self-efficacy Scale, Multi-Dimensional Emotional Empathy Scale, The Emotional Approach Coping Scale and personal information form have been used as data acquisition tools. As a result of path analysis, it was determined that the predicted path from emotional empathy to emotional approach coping was insignificant and thus it was taken out of the model. According to the modified path model, it was determined that there is a positive relationship between emotional self- efficacy and emotional empathy, that emotional self-efficacy positively affects emotional approach coping and happiness, that emotional empathy also positively affects happiness and that emotional approach coping also positively affects happiness.

    2007-07-01

    These lecture notes give a short review of methods such as the matrix ansatz, the additivity principle or the macroscopic fluctuation theory, developed recently in the theory of non-equilibrium phenomena. They show how these methods allow us to calculate the fluctuations and large deviations of the density and the current in non-equilibrium steady states of systems like exclusion processes. The properties of these fluctuations and large deviation functions in non-equilibrium steady states (for example, non-Gaussian fluctuations of density or non-convexity of the large deviation function which generalizes the notion of free energy) are compared with those of systems at equilibrium.

  20. Current tobacco use among middle and high school students--United States, 2011.

    2012-08-10

    Tobacco use continues to be the leading preventable cause of death and disease in the United States, with nearly 443,000 deaths occurring annually because of cigarette smoking and exposure to secondhand smoke. Moreover, nearly 90% of adult smokers begin smoking by age 18 years. To assess current tobacco use among youths, CDC analyzed data from the 2011 National Youth Tobacco Survey (NYTS). This report describes the results of that analysis, which indicated that, in 2011, the prevalence of current tobacco use among middle school and high school students was 7.1% and 23.2%, respectively, and the prevalence of current cigarette use was 4.3%, and 15.8%, respectively. During 2000-2011, among middle school students, a linear downward trend was observed in the prevalence of current tobacco use (14.9% to 7.1%), current combustible tobacco use (14.0% to 6.3%), and current cigarette use (10.7% to 4.3%). For high school students, a linear downward trend also was observed in these measures (current tobacco use [34.4% to 23.2%], current combustible tobacco use [33.1% to 21.0%], and current cigarette use [27.9% to 15.8%]). Interventions that are proven to prevent and reduce tobacco use among youths include media campaigns, limiting advertisements and other promotions, increasing the price of tobacco products, and reducing the availability of tobacco products for purchase by youths. These interventions should continue to be implemented as part of national comprehensive tobacco control programs and should be coordinated with Food and Drug Administration (FDA) regulations restricting the sale, distribution, and marketing of cigarettes and smokeless tobacco products to youths.
