185. Photoinduced phenomena in spin-coated vitreous As2S3and AsSe films

Author

Shtutina, S., Klebanov, M., Lyubin, V., Rosenwaks, S., and Volterra, V.

Abstract

Vitreous As2S3and AsSe films are prepared by the spin-coating technique from solutions of corresponding chalcogenide glasses in amines. The following photoinduced optical phenomena in the films are revealed and investigated: photodarkening, photoinduced linear dichroism, photodiffusion of silver and polarized photodoping. The photoinduced processes in the spin- coated films are compared with those observed in evaporated films of the same composition.

Abstract

This study investigates lexical organization and lexical retrieval in children with Williams syndrome (WS), by examining both naming accuracy and accompanying use of gestures in a picture-naming task. Ten children with the genetic disorder of Williams syndrome (age range: 9.5–12.9) were compared with 20 typically developing children, 10 matched for chronological age (CA) and 10 for mental-age (MA). Lexical production was measured by administering the Boston Naming test (BNT). Older typically developing children performed significantly better than the other two groups. No differences in accuracy were found between the children with WS and the typically developing children matched for mental-age. The overall distribution of error types displayed by children with WS indicate that the lexical-semantic organization is similar to that of typically developing children. However, compared to controls, the WS group produced more iconic gestures during the task, in patterns that suggest the existence of specific word-finding difficulties in these children. Results are discussed within the framework of recent theories on the role of gesture in speech production. [Copyright &y& Elsevier]

195. DEVELOPMENT OF AN HPLC METHOD FOR THE TOXICOLOGICAL SCREENING OF CENTRAL NERVOUS SYSTEM DRUGS.

Abstract

A simple and sensitive HPLC (high performance liquid chromatography) method has been developed for the qualitative and quantitative analysis of several CNS (central nervous system) drugs in clinical and forensic toxicology. The leading conditions were studied, namely parameters such as mobile phase pH, organic modifier percentage, and salt concentration. An isocratic HPLC elution, using a mobile phase composed of acetonitrile and pH 2.8 aqueous tetramethylammonium perchlorate and a C8 reversed phase column as the stationary phase, was found to be convenient for the separation of several CNS drugs, and for their detection and quantitation. The identification of the drugs was assured using their relative retention times, together with the peak area ratios at two different wavelengths (230 and 270 nm). A quick pre-treatment of the plasma samples, based on a SPE (solid phase extraction) procedure, with good extraction efficiency and satisfactory selectivity was developed. Under these conditions, a mixture of fifteen CNS drugs (including antipsychotics, antidepressants and antiepileptics) and some selected active metabolites, was well separated for identification and quantitative determination purposes.

Abstract

One of the most important challenges for embodied and grounded theories of cognition concerns the representation of abstract concepts, such as "freedom". Many embodied theories of abstract concepts have been proposed. Some proposals stress the similarities between concrete and abstract concepts showing that they are both grounded in perception and action system while other emphasize their difference favouring a multiple representation view. An influential view proposes that abstract concepts are mapped to concrete ones through metaphors. Furthermore, some theories underline the fact that abstract concepts are grounded in specific contents, as situations, introspective states, emotions. These approaches are not necessarily mutually exclusive, since it is possible that they can account for different subsets of abstract concepts and words. One novel and fruitful way to understand the way in which abstract concepts are represented is to analyze how sign languages encode concepts into signs. In the present paper we will discuss these theoretical issues mostly relying on examples taken from Italian Sign Language (LIS, Lingua dei Segni Italiana), the visual-gestural language used within the Italian Deaf community. We will verify whether and to what extent LIS signs provide evidence favoring the different theories of abstract concepts. In analyzing signs we will distinguish between direct forms of involvement of the body and forms in which concepts are grounded differently, for example relying on linguistic experience. In dealing with the LIS evidence, we will consider the possibility that different abstract concepts are represented using different levels of embodiment. The collected evidence will help us to discuss whether a unitary embodied theory of abstract concepts is possible or whether the different theoretical proposals can account for different aspects of their representation.
