Relationship of Early Childhood Neglect and Abuse with Emotion Regulation and Emotion Recognition in Adolescents

Background Different patterns of childhood neglect and abuse are related with the level of seriousness of mental issue in adulthood An investigation of this nature is essential to understand developmental trajectory of neglect and abuse and to base any intervention plan for affected individuals and to build up a risk alleviating techniques as primary prevention Aim To examine relationship of Childhood Neglect and Abuse with Emotion Regulation and Emotional Recognition in adolescents Method A purposive sample of 140 children studying in English and Hindi medium schools located in Delhi and NCR region India was taken to test the hypotheses Willing individuals of age range from 16 to 18 years of either sex were administered a set of self-administered questionnaires viz General Health Questionnaire GHQ Toronto Alexithymia Scale TAS Difficulties in Emotion Regulation Scale DERS and The Childhood Experience of Care and Abuse Questionnaire CECA for collecting the data Results The analysis indicated that GHQ cut-off score did not differ significantly on any of the study variables and the examined constructs sexual abuse physical abuse parental loss with difficult in emotion regulation and neglect physical abuse with alexithymia were positively correlated with Difficulty as measured on Emotion Regulation Scale and Toronto Alexithymia Scale Results also indicated that sexual abuse and physical abuse were significantly predicting difficulty in emotion regulation R 2 0 38 p 0 01 and alexithymia R 2 0 35 p 0 01 Conclusions Deficits in emotion regulation and emotion recognition were ubiquitous in children reporting of adverse childhood experience such as neglect and abuse Sexual and physical abuse emerged as significant variables accounting for maximum variance in criterion variables viz emotion regulation and recognitio

Electronic Structure and Thermoelectric Prospects of Phosphide Skutterudites

The prospects for high thermoelectric performance in phosphide skutterudites are investigated based on first principles calculations. We find that stoichiometric CoP_3 differs from the corresponding arsenide and antimonide in that it is metallic. As such the band structure must be modified if high thermopowers are to be achieved. In analogy to the antimonides it is expected that this may be done by filling with La. Calculations for LaFe_4P_12 show that a gap can in fact be opened by La filling, but that the valence band is too light to yield reasonable p-type thermopowers at appropriate carrier densities; n-type La filled material may be more favorable.Comment: 3 pages, 3 figures, 1 tabl

Controlling Mixing Inside a Droplet by Time Dependent Rigid-body Rotation

The use of microscopic discrete fluid volumes (i.e., droplets) as microreactors for digital microfluidic applications often requires mixing enhancement and control within droplets. In this work, we consider a translating spherical liquid droplet to which we impose a time periodic rigid-body rotation which we model using the superposition of a Hill vortex and an unsteady rigid body rotation. This perturbation in the form of a rotation not only creates a three-dimensional chaotic mixing region, which operates through the stretching and folding of material lines, but also offers the possibility of controlling both the size and the location of the mixing. Such a control is achieved by judiciously adjusting the three parameters that characterize the rotation, i.e., the rotation amplitude, frequency and orientation of the rotation. As the size of the mixing region is increased, complete mixing within the drop is obtained.Comment: 6 pages, 6 figure

Effect of geometrical size of the particles in a hot and dense hadron gas

Incorporation of the finite size of baryons into the equation of state (EOS) of a hot and dense hadron gas (HG) in a thermodynamically consistent manner has been a much studied problem. We first review its current status. Various models have been proposed in order to account for the repulsive force generated by the hard-core geometrical size of the baryons resulting in an excluded volume effect in the EOS. We examine the criterion of the thermodynamical consistency of these models and summarize their shortcomings. In order to remove the shortcomings, we propose a new model which incorporates the excluded volume effect in a thermodynamically consistent manner. We find that the new model works even for the cases of extremely large temperatures and densities where most of other approaches fail. Furthermore, the new expressions for thermodynamical variables resemble in form with those obtained from thermodynamically inconsistent models and thus a useful correction factor has been suggested here which converts inconsistent expressions into thermodynamically consistent ones. Finally we compare the predictions of new model with those obtained from various old models.Comment: 19 pages, 9 figures, accepted for publication in Phys. Rev.

Optimal Stochastic Enhancement of Photoionization

The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schr\"odinger equation. A modest amount of white noise results in an enhancement of the net ionization yield by several orders of magnitude, giving rise to a form of quantum stochastic resonance. We demonstrate that this effect is preserved if the white noise is replaced by broadband chaotic light.Comment: 4 pages, 4 figure
