Early influence of auditory stimuli on upper-limb movements in young human infants: an overview

Given that the auditory system is rather well developed at the end of the third trimester of pregnancy, it is likely that couplings between acoustics and motor activity can be integrated as early as at the beginning of postnatal life. The aim of the present mini-review was to summarize and discuss studies on early auditory-motor integration, focusing particularly on upper-limb movements (one of the most crucial means to interact with the environment) in association with auditory stimuli, to develop further understanding of their significance with regard to early infant development. Many studies have investigated the relationship between various infant behaviors (e.g., sucking, visual fixation, head turning) and auditory stimuli, and established that human infants can be observed displaying couplings between action and environmental sensory stimulation already from just after birth, clearly indicating a propensity for intentional behavior. Surprisingly few studies, however, have investigated the associations between upper-limb movements and different auditory stimuli in newborns and young infants, infants born at risk for developmental disorders/delays in particular. Findings from studies of early auditory-motor interaction support that the developing integration of sensory and motor systems is a fundamental part of the process guiding the development of goal-directed action in infancy, of great importance for continued motor, perceptual, and cognitive development. At-risk infants (e.g., those born preterm) may display increasing central auditory processing disorders, negatively affecting early sensorymotor integration, and resulting in long-term consequences on gesturing, language development, and social communication. Consequently, there is a need for more studies on such implications.

Educação física escolar: analisando o discurso e a ação docente

Facing the mechanical model that dominated the schools from the end of the 19th century to the 1970s, new movements for the Physical Education emerged during the 1980s. These movements aimed at breaking up with the military concept of sport that reigned so far. This way we assign a historical period marked by significant transformations in Brazilian Physical Education, especially in school, and they are related to the raise of new school proposals, such as: the developmentist, the constructivist and the critical-overcomer. All this considered, the present paper aims at analyzing if these tendencies really influenced the pedagogical practice of a group of Physical Education teachers in public schools of Serra Negra, SP.

Interpretações semânticas no pretérito perfeito: pretérito ou presente

An analysis of “Pretérito Perfeito Simples” (Simple Past Tense) and “Pretérito Per‐ feito Composto” (Compound Past Tense) in Brazilian Portuguese showed that such tenses must be distinguished according to semantic and pragmatic features other than temporal; both tenses can be used to express a situation that begins in the past and extends up to the present.

Quantum confinement in hydrogen bond of DNA and RNA

The hydrogen bond is a fundamental ingredient to stabilize the DNA and RNA macromolecules. The main contribution of this work is to describe quantitatively this interaction as a consequence of the quantum confinement of the hydrogen. The results for the free and confined system are compared with experimental data. The formalism to compute the energy gap of the vibration motion used to identify the spectrum lines is the Variational Method allied to Supersymmetric Quantum Mechanics.
