Getting into the musical zone: trait emotional intelligence and amount of practice predict flow in pianists

Being “in flow” or “in the zone” is defined as an extremely focused state of consciousness which occurs during intense engagement in an activity. In general, flow has been linked to peak performances (high achievement) and feelings of intense pleasure and happiness. However, empirical research on flow in music performance is scarce, although it may offer novel insights into the question of why musicians engage in musical activities for extensive periods of time. Here, we focused on individual differences in a group of 76 piano performance students and assessed their flow experience in piano performance as well as their trait emotional intelligence. Multiple regression analysis revealed that flow was predicted by the amount of daily practice and trait emotional intelligence. Other background variables (gender, age, duration of piano training and age of first piano training) were not predictive. To predict high achievement in piano performance (i.e., winning a prize in a piano competition), a seven-predictor logistic regression model was fitted to the data, and we found that the odds of winning a prize in a piano competition were predicted by the amount of daily practice and the age at which piano training began. Interestingly, a positive relationship between flow and high achievement was not supported. Further, we explored the role of musical emotions and musical styles in the induction of flow by a self-developed questionnaire. Results suggest that besides individual differences among pianists, specific structural and compositional features of musical pieces and related emotional expressions may facilitate flow experiences. Altogether, these findings highlight the role of emotion in the experience of flow during music performance and call for further experiments addressing emotion in relation to the performer and the music alike.
Analysis of translation model adaptation in statistical machine translation

Numerous empirical results have shown that combining data from multiple domains often improve statistical machine translation (SMT) performance. For example, if we desire to build SMT for the medical domain, it may be beneficial to augment the training data with bitext from another domain, such as parliamentary proceedings. Despite the positive results, it is not clear exactly how and where additional outof-domain data helps in the SMT training pipeline. In this work, we analyze this problem in detail, considering the following hypotheses: out-of-domain data helps by either (a) improving word alignment or (b) improving phrase coverage. Using a multitude of datasets (IWSLT-TED, EMEA, Europarl, OpenSubtitles, KDE), we show that sometimes outof-domain data may help word alignment more than it helps phrase coverage, and more flexible combination of data along different parts of the training pipeline may lead to better results.
Can the interactive whiteboard help to provide ‘dialogic space’ for children's collaborative activity?

This paper is based on a project investigating the use of interactive whiteboards (IWBs) as tools for children's group-based learning in primary science. A series of science activities were designed with participating teachers, in which groups of three or four children used the IWB to access information, consider options, plan actions and make joint decisions. Of particular interest in this paper is whether the IWB helps to provide a shared ‘dialogic space’ for reasoned discussion, within which children are able to jointly access relevant information, share different points of view and achieve collective solutions to science-based problems. Our analysis is framed by notions of ‘dialogic teaching’, in which the relationship between the guiding role of the teacher and children's active involvement in their own learning is highlighted. We offer some conclusions about the value of IWB technology for supporting children's talk and collaborative activity, which may assist its use and development.
Resistance to antivascular endothelial growth factor treatment in age-related macular degeneration

Age-related macular degeneration (AMD) is the main cause of visual impairment and blindness in people aged over 65 years in developed countries. Vascular endothelial growth factor (VEGF) is a positive regulator of angiogenesis and its proven role in the pathological neovascularization in wet AMD has provided evidence for the use of anti-VEGF agents as potential therapies. In this study, we review the literature for the possible causes of failure after treatment with anti-VEGF agents and attempt to propose an algorithm of suggestive actions to increase the chances of successful management of such difficult cases.
Personality Traits and the Consumption of Political Information

In this article, we examine the relationship between dispositional personality traits (the Big Five) and the consumption of political information. We present detailed hypotheses about the characteristics of the political environment that are likely to affect the appeal of politics and political information in general for individuals with different personalities as well as hypotheses about how personality affects the attractiveness of particular sources of political information. We find that the Big Five traits are significant predictors of political interest and knowledge as well as consumption of different types of political media. Openness (the degree to which a person needs intellectual stimulation and variety) and Emotional Stability (characterized by low levels of anxiety) are associated with a broad range of engagement with political information and political knowledge. The other three Big Five traits, Conscientiousness, Agreeableness, and Extraversion, are associated only with consumption of specific types of political information.
Functional interaction of Escherichia coli RNA polymerase with inorganic polyphosphate

RNA polymerase from the stationary growth phase cells of Escherichia coli is tightly associated with an acidic compound(s) and exhibits altered promoter selectivity, with reduced transcriptional activity of the genes highly expressed in the exponentially growing cells. Here we have examined the nature of the RNA polymerase‐associated acidic compound(s).
Multimer Formation and Ligand Recognition by the Long Pentraxin PTX3

PTX3 is a prototypic long pentraxin consisting of a C-terminal 203-amino acid pentraxin-like domain coupled with an N-terminal 178-amino acid unrelated portion. The present study was designed to characterize the structure and ligand binding properties of human PTX3, in comparison with the classical pentraxins C-reactive protein and serum amyloid P component. Sequencing of Chinese hamster ovary cell-expressed PTX3 revealed that the mature secreted protein starts at residue 18 (Glu). Lectin binding and treatment withN-glycosidase F showed that PTX3 isN-glycosylated, sugars accounting for 5 kDa of the monomer mass (45 kDa). Circular dichroism analysis indicated that the protein consists predominantly of β-sheets with a minor α-helical component. While in gel filtration the protein is eluted with a molecular mass of ≅900 kDa, gel electrophoresis using nondenaturing, nonreducing conditions revealed that PTX3 forms multimers predominantly of 440 kDa apparent molecular mass, corresponding to decamers, and that disulfide bonds are required for multimer formation. The ligand binding properties of PTX3 were then examined. As predicted based on modeling, inductive coupled plasma/atomic emission spectroscopy showed that PTX3 does not have coordinated Ca2+. Unlike the classical pentraxins CRP and SAP, PTX3 did not bind phosphoethanolamine, phosphocholine, or high pyruvate agarose. PTX3 in solution, bound to immobilized C1q, but not C1s, and, reciprocally, C1q bound to immobilized PTX3. Binding of PTX3 to C1q is specific and saturable with a K d 7.4 × 10−8 m as determined by solid phase binding assay. The Chinese hamster ovary cell-expressed pentraxin domain bound C1q when multimerized. Thus, as predicted on the basis of computer modeling, the prototypic long pentraxin PTX3 forms multimers, which differ from those formed by classical pentraxins in terms of protomer composition and requirement for disulfide bonds, and does not recognize CRP/SAP ligands. The capacity to bind C1q, mediated by the pentraxin domain, is consistent with the view that PTX3, produced in tissues by endothelial cells or macrophages in response to interleukin-1 and tumor necrosis factor, may act as a local regulator of innate immunity.
Effects of stress on emotional reactivity in hostile heavy social drinkers following dietary tryptophan enhancement.

AIM Because individuals high on hostility may be at risk for alcohol abuse due to serotonergic dysfunction and greater reactivity to stress, we examined the effects of acute dietary tryptophan enhancement and stress on mood and craving for alcohol in low-hostile (LoH) and high-hostile (HiH) individuals. METHODS Thirty-four LoH and 33 HiH heavy social drinkers [selection based on the Hostility scale from the Buss and Perry Aggression Questionnaire (1992)] received either tryptophan-enriched or control diet and underwent a stress-induction procedure. Trait differences between the two hostile groups were explored using personality, anxiety, and depression questionnaires. Mood, craving for alcohol, and salivary cortisol levels (CORT) were measured before and after tryptophan and after stress-induction. Heart rate (HR) was measured during stress-induction. RESULTS HiHs compared to LoHs scored higher on the depression and anxiety trait scales as well in the character dimension Harm Avoidance and reported more of stress exposure over the past month. They also showed more negative mood and higher craving for alcohol. Diet alone did not produce any subjective or physiological effects. Stress increased CORT, HR, negative mood, and craving for alcohol. HiHs displayed higher CORT increase and lower cardiovascular reactivity in response to stress compared to LoHs. Opposite to the predictions, tryptophan enhancement selectively facilitated stress-induced increase in craving in the HiHs. CONCLUSION Among heavy drinkers HiHs report higher craving for alcohol and show greater reactivity to stress as measured by CORT and negative mood. The effects of stress on craving in HiHs may be mediated by a serotonergic mechanism.
Pragmatic trellis coding applied to rectangular QAM

Although Ungerboeck's TCM (trellis coded modulation) is attractive in terms of high efficiency with low descending data rate by coding and high coding gain, it is difficult to implement. To remove this complexity, a pragmatic approach to the TCM, which is realized by employing the de facto convolutional code (constraint length K=7 and rate 1/2), was proposed. In this paper, a simpler realization of the TCM of rectangle type 2/sup N/ QAM (N is even number; /spl ges/ 4) by using the pragmatic approach is presented. We have independently shown the convolutional coding and the Viterbi decoding by the decomposition from two-dimensions into each one-dimension. By this decomposition, it is possible to apply the pragmatic approach to minimize the hardware and cost. Therefore, it is very useful for 64 QAM or 256 QAM applications such as digital video broadcasting over digital cable TV (ITU-T J.83) and fixed wireless access (IEEE 802.16) systems. It can be applied not only to single carrier QAM but also to multi-carrier QAM like OFDM.
How the Context Matters. Literal and Figurative Meaning in the Embodied Language Paradigm

The involvement of the sensorimotor system in language understanding has been widely demonstrated. However, the role of context in these studies has only recently started to be addressed. Though words are bearers of a semantic potential, meaning is the product of a pragmatic process. It needs to be situated in a context to be disambiguated. The aim of this study was to test the hypothesis that embodied simulation occurring during linguistic processing is contextually modulated to the extent that the same sentence, depending on the context of utterance, leads to the activation of different effector-specific brain motor areas. In order to test this hypothesis, we asked subjects to give a motor response with the hand or the foot to the presentation of ambiguous idioms containing action-related words when these are preceded by context sentences. The results directly support our hypothesis only in relation to the comprehension of hand-related action sentences.
The relations of regulation and emotionality to problem behavior in elementary school children

Abstract The relations of regulation and emotionality to elementary school children's problem behavior was examined. Parents and teachers reported on children's problem behavior. One parent and teachers rated children on various measures of regulation (including resiliency) and emotionality; children's baseline heart rate and facial reactivity were assessed; and physiological and facial distress and gaze aversion while viewing a distress film sequence were measured. In general, low regulation, negative emotionality, and general and positive emotional intensity predicted problem behaviors. Teachers' reports of negative emotionality and regulation interacted in their relation to problem behaviors, with regulation apparently buffering the effects of moderate and high negative emotionality. Baseline heart rate and facial distress were related to low levels of problem behavior, and gaze aversion during the distress film segment was associated with low levels of problem behavior.
CONTRIBUIÇÃO PARA O ESTUDO DA ADAPTAÇÃO PORTUGUESA DAS ESCALAS DE ANSIEDADE, DEPRESSÃO E STRESS (EADS) DE 21 ITENS DE LOVIBOND E LOVIBOND

Anxiety and depression are clearly distinct from a phenomenological point of view. Nevertheless it has proven to be difficult to distinguish these constructs empirically. The scale in the present study intends to evaluate these constructs under the perspective of the tripartite model. The aims of the present study is the adaptation to Portuguese of the Depression Anxiety Stress Scales that in Portuguese become Escalas de Ansiedade Depressao e Stress (EADS-21) with the number 21 designating the number of items distributed in equal numbers by three scales, Depression, Anxiety and Stress. The subjects rate the extent to which they have experienced each symptom over the past week, on a 4-point severity/frequency scale. The EADS items were developed following a theoretical methodology confirmed by an empirical study of the theoretical model. Participants were a convenience sample of 200 Ss, between 18 and 23 years of
Primate Communication and the Gestural Origin of Language

Wallace, Tylor, Wundt, Johannesson, and others have proposed that human language had its basis in hand and arm gestures. The Gardners' work with the chimpanzee Washoe, Premack's study of the chimpanzee Sarah, and continuing experiments along these lines indicate that neural restructuring would not have been necessary for the protohominid acquisition of a simple propositional gesture or sign language which did not involve cross-modal transfer at a high level from the visual to the auditory channel or vice versa. Evidence from primate studies, early tool-using, the continuing functions of gesture in human communication, lateral dominance in its relation to speech and tool manipulation, and other sources is presented to support a model of glottogenesis. It is argued that a preexisting gestural language system would have provided an easier pathway to vocal language than a direct outgrowth of the "emotional" use of vocalization characteristic of nonhuman primates.
The Prevalence of Pulp stones in Adult Patients of Shiraz Dental School, a Radiographic Assessment

Statement of the Problem Pulp stones are calcifications found in the pulp chamber or pulp canals of the teeth. Its different prevalence in different population is a matter of concern. Purpose This study aimed to assess the prevalence of pulp stones in a sample of Iranian population and to report its occurrence regarding gender, dental arch, tooth type and dental status. Materials and Methods Dental records of patients who attended Shiraz Dental School were selected randomly. Only bitewing and periapical radiographs of maxillary and mandibular permanent posterior teeth were studied. Teeth were classified in the case of presence or absence of pulp stones, and the prevalence was analyzed in different gender, tooth types, dental arch, and dental status (intact, carious, or restored) groups. Statistical analysis was performed using X2 test. Results Of the 652examined subjects, 306 (46.9%) had one or more teeth with pulp stones. Of the 8244 posterior teeth examined, 928 (11.25%) had pulp stones in the pulp chamber. These pulp stones were detected in 76(37.6%) of males and 230 (51%) of females. The frequency of pulp stones among different teeth between maxillary and mandibular arches had almost a similar pattern. Among teeth demonstrating the condition, first molars were the most prevalent, followed by second molars. In maxillary molars the frequency of occurrence (26%) was higher than mandibular molars (18.7%). No Significant difference was found between dental status and pulp stones occurrence. Conclusion The occurrence of pulp stones noted in this study was significantly higher in female, molar teeth than premolar and 1st maxillary molar than mandibular. There was no significant association between pulp stone and condition of the crown.
Paramedics' non-technical skills: a literature review

Healthcare organisations have started to examine the impact that the human worker has on patient safety. Adopting the Crew Resource Management (CRM) approach, used in aviation, the CRM or non-technical skills of anaesthetists, surgeons, scrub practitioners and emergency physicians have recently been identified to assist in their training and assessment. Paramedics are exposed to dynamic and dangerous situations where patients have to be managed, often with life-threatening injuries or illness. As in other safety-critical domains, the technical skills of paramedics are complemented by effective non-technical skills. The aim of this paper was to review the literature on the non-technical (social and cognitive) skills used by paramedics. This review was undertaken as part of a task analysis to identify the non-technical skills used by paramedics. Of the seven papers reviewed, the results have shown very little research on this topic and so reveal a gap in the understanding of paramedic non-technical skills.
Nasal Patches and Curves for Expression-Robust 3D Face Recognition

The potential of the nasal region for expression robust 3D face recognition is thoroughly investigated by a novel five-step algorithm. First, the nose tip location is coarsely detected and the face is segmented, aligned and the nasal region cropped. Then, a very accurate and consistent nasal landmarking algorithm detects seven keypoints on the nasal region. In the third step, a feature extraction algorithm based on the surface normals of Gabor-wavelet filtered depth maps is utilised and, then, a set of spherical patches and curves are localised over the nasal region to provide the feature descriptors. The last step applies a genetic algorithm-based feature selector to detect the most stable patches and curves over different facial expressions. The algorithm provides the highest reported nasal region-based recognition ranks on the FRGC, Bosphorus and BU-3DFE datasets. The results are comparable with, and in many cases better than, many state-of-the-art 3D face recognition algorithms, which use the whole facial domain. The proposed method does not rely on sophisticated alignment or denoising steps, is very robust when only one sample per subject is used in the gallery, and does not require a training step for the landmarking algorithm.
Generation of Active Protein Phosphatase 2A Is Coupled to Holoenzyme Assembly

Protein phosphatase 2A (PP2A) is a prime example of the multisubunit architecture of protein serine/threonine phosphatases. Until substrate-specific PP2A holoenzymes assemble, a constitutively active, but nonspecific, catalytic C subunit would constitute a risk to the cell. While it has been assumed that the severe proliferation impairment of yeast lacking the structural PP2A subunit, TPD3, is due to the unrestricted activity of the C subunit, we recently obtained evidence for the existence of the C subunit in a low-activity conformation that requires the RRD/PTPA proteins for the switch into the active conformation. To study whether and how maturation of the C subunit is coupled with holoenzyme assembly, we analyzed PP2A biogenesis in yeast. Here we show that the generation of the catalytically active C subunit depends on the physical and functional interaction between RRD2 and the structural subunit, TPD3. The phenotype of the tpd3Δ strain is therefore caused by impaired, rather than increased, PP2A activity. TPD3/RRD2-dependent C subunit maturation is under the surveillance of the PP2A methylesterase, PPE1, which upon malfunction of PP2A biogenesis, prevents premature generation of the active C subunit and holoenzyme assembly by counteracting the untimely methylation of the C subunit. We propose a novel model of PP2A biogenesis in which a tightly controlled activation cascade protects cells from untargeted activity of the free catalytic PP2A subunit.

Deep-Level Similarity and Group Social Capital: Associations With Team Functioning

This study examines the associations of deep-level and surface-level similarity with team functioning (i.e., team effectiveness, team in-role performance, and team satisfaction). Hypotheses were tested using data from 420 teachers in 57 teams in secondary education. These teams were tightly integrated units in which teachers from different functional areas had to work together. From the results of multilevel analyses, it appeared that especially deep-level similarity was important for team functioning. Cross-level interactions showed a moderating effect of group social capital on the association of deep-level similarity with team functioning, but there was no such relationship found for surface-level similarity. Especially in teams with high group social capital, deep-level similarity was associated with improved team functioning.
Authenticity, Tourism, and Self-discovery in Thailand: Self-creation and the Discerning Gaze of Trekkers and Old Hands

Through an analysis of tourist-related advertisements and literature, as well as some ethnographic work among tourists, I argue that hill-tribe tourism and sex tourism in Thailand are a means by which white [farang] tourists attempt to identify authenticity and incorporate this sense of the authentic into their own identity. Tourists (and ethnographers alike) attempt to become experts at distinction in order to perceive a truer sense of "self" through authentic interaction with Thais. This interaction is always problematic, however, as the tourist's pre-conceived image of the country continually differs from the reality, especially outside of those spaces designed for tourists, thus provoking a sense of anxiety about the truth of interactions between the tourist and the toured.
