The Effect of Educational Background on Politeness Among the Students of Stain Jurai Siwo Metro

Humans are social creatures who need other humans to fullfil their needs, communication and interaction have a crucial role to fullfil those needs. In order  to the communication process can proceed smoothly, then at least human need to speak in polite in the communication. Religious norms and the community shows that politeness is necessary to properly maximized. Politeness in the relating of  the Holy Qur\u27an about pronunciation, gestures and vocabulary was polite and adapted to the circumstances (environment). In social life, politeness is usually used to show respect for older people, but it would be better also if used against a fellow or a younger person. Politeness will minimize conflict and hostility. Because of it, the institution is one way of language education. STAIN Jurai Siwo Metro is an Islamic institution, that   students have many educational backgrounds and is so different each other.  Based on the mapping carried out showed that students of English Department Program, the majority coming from Senior High School (SMA).  This study aims to determine the reality of politeness and influence of the educational background to the student politeness in English Study Program STAIN Jurai Siwo Metro. The method used in this research is quantitative descriptive, where interviews, observation and documentation used by researchers in collecting and obtaining data. From the data obtained show that the reality of politeness students have to realize elements of politeness. Furthermore, based on analysis of the data also showed that educational background gives affect student in politeness

Optical phonons in new ordered perovskite Sr2Cu(Re0.69Ca0.31) Oy system observed by infrared reflectance spectroscopy

We report infrared reflectivity spectra for a new correlated cupric oxide system Sr2Cu(Re0.69Ca0.31)Oy with y ~ 0.6 at several temperatures ranging between 8 and 380 K. The reflectivity spectrum at 300 K comprises of several optical phonons. A couple of residual bands located around 315 and 653 cm-1 exhibit exceptionally large intensity as compared to the other ones. The overall reflectivity spectrum lifts up slightly with increasing temperature. The energy and damping factor of transverse-optical phonons are determined by fitting the imaginary dielectric constant by Lorentz oscillator model and discussed as a function of temperature in terms of lattice anharmonicity.Comment: 9 pages, 3 figures, presented at ISS2005, to appear in Physica

Laser ignition of an optically sensitised secondary explosive by a diode laser

As a green technology, laser ignition of a relatively insensitive secondary explosive has been experimentally investigated. The explosive, hexanitrostilbene (HNS), was doped with one of two optical sensitizers, carbon black or a laser absorbing dye, and a continuous-wave (CW) infrared diode laser was used as the igniting source. The ignition sensitivities of HNS with each of the two optical sensitizers were analysed and compared in terms of: optical power threshold for ignition, ignition delay and full burn delay at various laser powers. The results have shown that both the chemical dye and carbon black optically sensitize the explosive with similar efficiencies. In contrast to the carbon black, the dye provides wavelength specificity and selectivity in the laser ignition process and its solubility in some specific solvents improves the coating of the explosive material. It was therefore concluded that the laser absorbing dye is a better candidate for optical sensitization in laser ignition than the commonly used carbon black. The combination of laser ignition sensitivity with wavelength selectivity potentially offers higher reliability and safety at a low optical power for future ignitors of secondary explosives

Generalized Parton Distributions from Hadronic Observables

We propose a physically motivated parametrization for the unpolarized generalized parton distributions, H and E, valid at both zero and non-zero values of the skewness variable, \zeta. At \zeta=0, H and E are determined using constraints from simultaneous fits of experimental data on both the nucleon elastic form factors and the deep inelastic structure functions. Lattice calculations of the higher moments constrain the parametrization at \zeta > 0. Our method provides a step towards a model independent extraction of generalized distributions from the data that is alternative to the mathematical ansatz of double distributions.Comment: 4 pages, 2 figures, to appear in the proceedings of DIS 200
