Jonathan J. Webster & Carmel Cloran (eds.) Describing language: Form and function, volume 5 in the collected works of Ruqaiya Hasan

The aim of this research was to describe the local language form, function, and typical of it in the directive act at the university in Central Sulawesi. The method used in this research was descriptive qualitative in socio-pragmatics approach. The source of the data was gained from lecturers and students utterances in discourse lecture. The data collection used note taking. Meanwhile, the techniques of analyzing data were the interactive analysis that consisted of four steps, namely data collection, data reduction, data analysis, and verification or drawing the conclusion. The result of the research shows that the local language form in directive act consisted of imperative, interrogative, and declarative. The functions of local language in directive acts are the prohibitive function, suggestive function, requestive, and permissive function. The typical local language that used is characterized by regional language and its dialect.

The Relationship

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).
