The purpose of the present research was to translate into Spanish and analyze the psychometricA properties of the Situational Motivation Scale (SIMS). The participants were 373 undergraduate students (126 males and 247 females). Factor validity was tested via confirmatory factor analysis. Based on factor loadings and modification indexes, the SIMS was reduced to a 14-item model. This respecific...

We introduce a procedure, called the Degree Sequence Index Strategy (DSI), by which to bound graph invariants by certain indices in the ordered degree sequence. As an illustration of the DSI strategy, we show how it can be used to give new upper and lower bounds on the k-independence and the k-domination numbers. These include, among other things, a double generalization of the annihilation num...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
