Hf isotope ratios measured in igneous zircon are controlled by magmatic source, which may be linked to tectonic setting. Over the 200-500 Myr periodicity of the supercontinent cycle - the principal geological phenomenon controlling prevailing global tectonic style - juvenile Hf signals, i.e. most radiogenic, are typically measured in zircon from granites formed in arc settings (crustal growth),...

the purpose of this study is to investigate the relation between identity styles and commitment with quality of friendship among the students in third grade of high school. 400 participants from nineteen educational districts were chosen randomly. three quesnonnaires were used: identity style inventory, the quality of friendship, the reciprocity of friendship . the results indicated that inform...

Professional programmers need common coding conventions to assure co-operation and a degree of quality of the software. Novice programmers, however, easily forget issues of programming style in their programming coursework. In particular with large classes, students may pass several courses without learning elements of programming style. This is often due to shortage of tutor work to give stude...

Data from the Sloan Digital Sky Survey has given evidence of structures within the Milky Way halo from other nearby galaxies. Both the halo and these structures are approximated by densities based on geometric objects. A model of the data is formed by a mixture of geometric densities. By using an EM-style algorithm, we optimize the parameters of our model in order to separate out these structur...

We study the continuation passing style (CPS) transform and its generalization, the computational transform, in which the notion of computation is generalized from continuation passing to an arbitrary one. To establish a relation between direct style and continuation passing style interpretation of sequential call-by-value programs, we prove the Retraction Theorem which says that a lambda term ...

Crustal plateaus and volcanic rises, major physiographic features on Venus, both formed over mantle plumes. Crustal plateaus were produced by large degrees of plume melting beneath thin lithosphere. The oldest tectonic features in crustal plateaus are ribbon-like troughs indicating early uplift and tensile stretching; their shallow depths suggest that surface temperature there was higher in the...

Life is evolving fast (at least in the first world) and the latest technological gadget becomes outdated even before we have learnt how to use it. In this respect, science is no exception. The new buzzword ‘Systems Biology’ entered the vocabulary of the scientific community only a few years ago. Now that every biologist is aware of it and almost everyone seems to be doing it, an even newer buzz...

This is a survey paper on various weak systems of Feferman’s explicit mathematics and their proof theory. The strength of the systems considered in measured in terms of their provably terminating operations typically belonging to some natural classes of computational time or space complexity.

This paper proposes an architectural style for the definition of software product lines architectures and also a strategy for the instantiation of specific products derived from the architecture. This style is defined as a seamless extension of AspectualACME, characterizing the PLAspectualACME architectural description language, which uses the original abstractions of ACME and Armani’s formal c...

the purpose of this quantitative correlation study was to determine the extent to which the role of leadership style preferences correlate with employee satisfaction with supervision among employees and leaders of an iranian oil company. this study measured preferences for each of five common leadership styles and examined correlations with measures of employee satisfaction. the styles studied ...
