We describe two methods to perform sentiment analysis both on long and short texts written in Spanish language. We first present an unsupervised method based on dependency parsing which calculates the semantic orientation (SO) of the sentences in order to classify the polarity. We then propose a hybrid approach which uses the computed SO and lexico-syntactic knowledge as features for a supervis...

Objectives: The current research sought to establish the protective roles of individual difference factors associated with a positive self-orientation and also evaluate the role of personality vulnerability factors as predictors of depression in children from China. The main focus was on individual differences in feelings of mattering to other people. Methods: A sample of 218 children in grade ...

We calculate energies of shallow donors confined in a rolled-up quantum well the presence electric field by solving numerically Schrödinger equation natural curvilinear coordinates. It is found that curves density states (DOSs) are very sensitive to variation donor position, geometry spiral and applied value. Novel results for dependencies donor’s dipole moment its polarizability on strength or...

Atomic-scale finite element procedure for modeling of self-positioning nanostructures is developed. Our variant of the atomic-scale finite element method is based on a meshless approach and on the Tersoff interatomic potential function. The developed algorithm is used for determination of equilibrium configuration of atoms after nanostructure self-positioning. Dependency of the curvature radius...

This paper presents the design and development of a visual computer system for the modelling and simulation of human movements. The interface allows human figure movements to be generated in a graphical and intuitive way, accomplishing human-computer interaction through 3D icons-graphics. In the implementation object oriented programming methodology is used. A hierarchical dependency between th...

Money has been said to change people's motivation (mainly for the better) and their behavior toward others (mainly for the worse). The results of nine experiments suggest that money brings about a self-sufficient orientation in which people prefer to be free of dependency and dependents. Reminders of money, relative to nonmoney reminders, led to reduced requests for help and reduced helpfulness...

Thickness dependency of the field emission of amorphous and nanostructured carbon thin films has been studied. It is found that in amorphous and carbon films with nanometer-sized sp2 clusters, the emission does not depend on the film thickness. This further proves that the emission happens from the surface sp2 sites due to large enhancement of electric field on these sites. However, in the case...

background: although extensive development of technology provides welfare and accessibility for families but it may be one of the threatening factors for them. the unique characteristics of internet such as availability and facility are useful, but over using for its exciting content cause to internet addiction between family members. the aim of this study was to explain the experiences of the ...
