Developing Forensic Communication

In any way, criminal doers more likely to avoid the legal punishment. One of the possible ways is making statements or narrations to camouflage their crimes. Here we found a forensic communication: is there any evil intention hidden the words. To develop forensic communication, I would like to explain discourse analysis techniques to find the motive and purpose. For a forensic method, discourse analysis technique has not been yet widely used in the disclosure of the crime.     Keywords: crime, narration, forensic communication, discourse analysi

Komunikasi Sebagai Wacana

The purpose of this article is to describe communication as discourse perspective. In this perspective communication is seen an activity to construct of reality into a discourse that some interests entering the discourse. The perspective is to complete to the others ones, first transmissions perspective. Communication is to transmit of messages linearly. Second, perspective of display. Communication is an effort to exhibit many messages for gaining audiences attention. Third, generating of meaning perspective where we use symbols to create meaning. Fourth, ritual perspective which communication as a rites to maintain commonness and solidarity of the participants

Memahami Komunikasi Pemasaran Politik

This article explores political marketing communication as a means of political communication using concept and marketing communication techniques to buy political product. According to the goals (such as position, title, and wealth), what considered as political communication products in its broadest terms are leadership, institution, membership, policy, and political activities. Principles, methods, and stages of political communication must be attended seriously so that the product being sold would be embraced by political audience

Konstruksi Realitas Politik dalam Media Massa (Studi Pesan Politik dalam Media Cetak pada Masa Pemilu 1999)

During the 1999-campaign period generally the mass media in Indonesia constructed political parties like a music group; and present the politicians acts as celebrities. At that time, national newspapers describe political parties as the instrument to harvested masses. Meanwhile the political party functions, as broker within the clearinghouse of ideas in the democratic lives didn’t appear within the political party’s discourse. In spite of the media have different interests one each other in news making the political parties, such as ideological, idealism, political, and economic or market factors.&nbsp

Modeling power grids

We present a method to construct random model power grids that closely match statistical properties of a real power grid. The model grids are more difficult to partition than a real grid.Comment: 9 pages, 5 figure

Effects of semiclassical spiral fluctuations on hole dynamics

We investigate the dynamics of a single hole coupled to the spiral fluctuations related to the magnetic ground states of the antiferromagnetic J_1-J_2-J_3 Heisenberg model on a square lattice. Using exact diagonalization on finite size clusters and the self consistent Born approximation in the thermodynamic limit we find, as a general feature, a strong reduction of the quasiparticle weight along the spiral phases of the magnetic phase diagram. For an important region of the Brillouin Zone the hole spectral functions are completely incoherent, whereas at low energies the spectral weight is redistributed on several irregular peaks. We find a characteristic value of the spiral pitch, Q=(0.7,0.7)\pi, for which the available phase space for hole scattering is maximum. We argue that this behavior is due to the non trivial interference of the magnon assisted and the free hopping mechanism for hole motion, characteristic of a hole coupled to semiclassical spiral fluctuations.Comment: 6 pages, 5 figure

Transport properties of a two impurity system: a theoretical approach

A system of two interacting cobalt atoms, at varying distances, was studied in a recent scanning tunneling microscope experiment by Bork et. al.[Nature Phys. 7, 901 (2011)]. We propose a microscopic model that explains, for all experimentally analyzed interatomic distances, the physics observed in these experiments. Our proposal is based on the two-impurity Anderson model, with the inclusion of a two-path geometry for charge transport. This many-body system is treated in the finite-U slave boson mean-field approximation and the logarithmic-discretization embedded-cluster approximation. We physically characterize the different charge transport regimes of this system at various interatomic distances and show that, as in the experiments, the features observed in the transport properties depend on the presence of two impurities but also on the existence of two conducting channels for electron transport. We interpret the splitting observed in the conductance as the result of the hybridization of the two Kondo resonances associated with each impurity.Comment: 5 pages, 5 figure

Preparation and characterization of some unsaturated polyester alkyds based on terephthalic and isophthalic acids

In this work unsaturated polyesters based on terephthalate acid and isophthalic acid have been prepared by a two-stage process. In the first stage the prepolymer bis(2-hydroxypropyl) terephthalate (PTP1) was prepared and purified. PTPl was heated at different temperatures within the range lSO-1800 C, and the changes in molecular weight distribution, on heating, and the considerable ester-interchanges were assessed by gel permeation chromatography (GPC) and nuclear magnetic resonance spectroscopy (NMR). Similar experiments were performed with the prepolymer (P(TP)J provided by Imperial Chemical Industries and the prepolymer bis(hydroxypropyl) isophthalate (PIP1) which was synthesised and purified. GPC and NMR were used to compare the temperature dependence of ester-interchange and polycondensation in the three prepolymers. In order to see the implications of the ester-interchange observed on the mechanism of the reaction between prepolymer and maleic anhydride, unsaturated polyesters produced at various temperatures in short reaction times have been fractionated by preparative GPC. High resolution 300 MHz proton NMR was used for the qualitative and quantitative analysis of the unsaturated polyester and its fractions~ $tructures were assigned to the oligomeric compounds and reaction mechanisms were outlined. -Finally the products of the reaction of (PTP1), propylene glycol, maleic anhydride (or fumaric acid) in various molar ratios were examined by NMR and GPC, and their results were compared with a study of unsaturated polyesters based on (P(TP)n) and (PIP1)

Selfconsistent hybridization expansions for static properties of the Anderson impurity model

By means of a projector-operator formalism we derive an approximation based on a self consistent hybridization expansion to study the ground state properties of the Anderson Impurity model. We applied the approximation to the general case of finite Coulomb repulsion $U$, extending previous work with the same formalism in the infinite-$U$ case. The treatment provides a very accurate calculation of the ground state energy and their related zero temperature properties in the case in which $U$ is large enough, but still finite, as compared with the rest of energy scales involved in the model. The results for the valence of the impurity are compared with exact results that we obtain from equations derived using the Bethe ansatz and with a perturbative approach. The magnetization and magnetic susceptibility is also compared with Bethe ansatz results. In order to do this comparison, we also show how to regularize the Bethe ansatz integral equations necessary to calculate the impurity valence, for arbitrary values of the parameters.Comment: 8 pages, 5 figure
