Statistical analysis of human boy movement and group interactions in response to music

Quantification of time series that relate to physiological data is challenging for empirical music research. Up to now, most studies have focused on time-dependent responses of individual subjects in controlled environments. However, little is known about time-dependent responses of between-subject interactions in an ecological context. This paper provides new findings on the statistical analysis of group synchronicity in response to musical stimuli. Different statistical techniques were applied to time-dependent data obtained from an experiment on embodied listening in individual and group settings. Analysis of inter group synchronicity are described. Dynamic Time Warping (DTW) and Cross Correlation Function (CCF) were found to be valid methods to estimate group coherence of the resulting movements. It was found that synchronicity of movements between individuals (human human interactions) increases significantly in the social context. Moreover, Analysis of Variance (ANOVA) revealed that the type of music is the predominant factor in both the individual and the social context

IFSS, TG, FT-IR spectra of impregnated sugar palm (Arenga pinnata) fibres and mechanical properties of their composites.

This study aimed to investigate the effect of resin impregnation on the interfacial shear strength (IFSS), thermogravimetric (TG) and fourier transform infrared (FT-IR) of sugar palm (Arenga pinnata) fibres. In addition, the effect of resin impregnation on the mechanical properties of sugar palm fibre reinforced unsaturated polyester (UP) composites was also studied. The fibres were impregnated with UP via vacuum resin impregnation process at a pressure of 600 mmHg for 5 min. Composites of 10, 20, 30, 40 and 50 % fibre loadings were fabricated and tested for tensile and flexural properties. It was observed that the impregnation process caused the fibres to be enclosed by UP resin and this gave a strong influence to the increase of its interfacial bonding by the increase of its IFSS from single fibre pull-out test. It was also observed with TG and FT-IR spectra that the impregnated fibre had lower moisture uptake than the control and there was no significant increase in thermal stability of the impregnated fibre. The sequence of fibre decomposition started from the evaporation of moisture, hemicelluloses, cellulose, lignin and finally ash content and the presence of these components were proven by FT-IR spectra. For the composite specimens, due to the high interfacial bonding of the impregnated fibre and the matrix, the impregnated composites showed consistently higher tensile strength, tensile modulus, elongation at break, flexural strength, flexural modulus and toughness than the control samples. It was also observed that 30 % fibre loading gave optimum properties

Systematic review of dexketoprofen in acute and chronic pain

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Background: Dexketoprofen, an NSAID used in the management of acute and chronic pains, is licensed in several countries but has not previously been the subjected of a systematic review. We used published and unpublished information from randomised clinical trials (RCTs) of dexketoprofen in painful conditions to assess evidence on efficacy and harm. Methods: PubMed and Cochrane Central were searched for RCTs of dexketoprofen for pain of any aetiology. Reference lists of retrieved articles and reviews were also searched. Menarini Group produced copies of published and unpublished studies (clinical trial reports). Data were abstracted into a standard form. For studies reporting results of single dose administration, the number of patients with at least 50 % pain relief was derived and used to calculate the relative benefit (RB) and number-needed-to-treat (NNT) for one patient to achieve at least 50 % pain relief compared with placebo. Results: Thirty-five trials were found in acute pain and chronic pain; 6,380 patients were included, 3,381 receiving dexketoprofen. Information from 16 trials (almost half the total patients) wa

Friendship Relationships in Children and Adolescents: Positive Development and Prevention of Mental Health Problems

Studying childhood and adolescence from the perspective of Positive Development involves seeing them from the creation of skills and values that allow the child and the adolescent to move towards adulthood in a successful way, as well as considering them from the avoidance and prevention of violence, addiction, depression and other mental health problems.Developmental Psychology theorists such as Harry Stack Sullivan have put forward that friendships can provide a unique developmental context in which children and adolescents learn about Conflict and Negotiation and develop Perspective Taking Skills and Empathic Concern; also in that relationship, furthermore, they satisfy social needs of Companionship and Intimacy.First of all, in this chapter it is presented the Argentine adaptation of Bukowski Friendship Quality Scale (children´s version), an instrument that evaluates friendship quality and explores six dimensions of peer relationships: Companionship, Balance, Conflict, Help, Security and Closeness.Subsequently, two studies conducted with this instrument, in the adolescent version, are presented. The first study evaluates the relationship between Friendship quality and Loneliness feelings in adolescents. It is observed that the rejection of peers and loneliness self-perception feelings with their peers, are negatively correlated with Friendship quality dimensions: Balance, Companionship, Help, Security and Closeness. The Conflict Friendship dimension correlates positively with Family loneliness and Peer loneliness.In the second study, it is presented the results of the hierarchical regressions performed to evaluate Empathy and Values dimensions as predictive variables of Friendship Quality dimensions. Regarding Value Scale, Honesty is the best predictor of Friendship Quality dimensions; and regarding Empathy, Perspective Taking and Empathic Concern are the best predictors of Friendship Quality dimensions.Finally, it is considered how these contributions highlight the important role of friendship and peer relationships in the prevention of mental health problems.Fil: Rodriguez, Lucas Marcelo.
