We quantified the multiscale clustering in the acoustics of infant prelinguistic vocalizations, the development across the first two years of life, and the relationship between caregivers' vocalizations for fifteen infant-caregiver dyads. The multiscale structure of infant utterances, spanning from seconds to over one hour was similar to that of caregivers, providing new evidence for the multis...

Some researchers argue that gestures serve an interpersonal function, such as making the intended message clear (e.g., Gallagher & Frith, 2003; cf. Kita, 2000). In this study, we tested whether gestures serve an interpersonal function, specifically predicting that the higher participants’ autism spectrum quotient, the less frequently they would gesture. Participants completed the Autism Spectru...

Infants undergo a series of dynamic changes during the first year of their life, starting at nearly complete dependence upon others for all functions, culminating with the ability to self-transport and rudimentarily converse around the age of 12 months. Previous research indicates an interaction between walking and expressive and receptive language development. Given that phonology underlies ex...

Since developments of computerised information systems practically used in the market, many things has been swiftly and progressively changed in surveying profession; because the volubility of the positioning/spatial information has been well understood by the other professions who deal with the information systems. In fact, at the beginning, information systems have been developed without any ...

T he first general anesthesia for human surgery was administered at the Massachusetts General Hospital in Boston in 1846. The patient was put to sleep by breathing diethyl ether from a glass vesicle. and the surgeon quickly dissected a tumor located under the jaw. After completing the operation the surgeon remarked to his audience, “Gentlemen, this is no humbug. ” Since this first successful de...

Cooperation is central to human communication. The foundation of cooperative verbal communication is taking turns to speak. Given the universality of turn-taking, it is natural to ask how it evolved. We used marmoset monkeys to explore whether another primate species exhibits cooperative vocal communication by taking turns. Marmosets share with humans a cooperative breeding strategy and volubil...

In humans, vocal turn-taking is a ubiquitous form of social interaction. It is a communication system that exhibits the properties of a dynamical system: two individuals become coupled to each other via acoustic exchanges and mutually affect each other. Human turn-taking develops during the first year of life. We investigated the development of vocal turn-taking in infant marmoset monkeys, a Ne...

We examined the ability of a halophilic bacterium (WFP 1A) isolated from the Waste Isolation Pilot Plant (WIPP) site to accumulate uranium in order to determine the potential for biocolloid facilitated actinide transport. The bacterial cell Surface functional groups involved in the complexation of the actinide were determined by titration. Uranium, added as uran y] nitrate, was removed from sol...
