 Brazilian Journalism Research , 2010, Abstract: This article addresses the emergence of contemporary collective photographic practice linked to photojournalism. As a theoretical framework, intersections are made with the consolidation of a new image system, recovering the previous history of photography and its interaction with journalism. In this sense, it aims to work initially with a set of characteristics and constraints which act together to define the problem. In addition, it presents a case analysis, the Cia. da Foto (Photo Company), and shows how it represents the consolidation and/or the contradictions of the phenomenon.
 Michael J. Kozdron Mathematics , 2007, Abstract: We review some recently completed research that establishes the scaling limit of Fomin's identity for loop-erased random walk on Z^2 in terms of the chordal Schramm-Loewner evolution (SLE) with parameter 2. In the case of two paths, we provide a simplified proof of the identity for loop-erased random walk and simple random walk, and prove directly that the corresponding identity holds for chordal SLE(2) and Brownian motion. We also include a brief introduction to SLE and discussion of the relationship between SLE(2) and loop-erased random walk.
 Paul Lester Journal of Educational Media & Library Sciences , 1988, Abstract: 無 The methods used to teach photojournalism ethics can be divided into two groups. There is the lecture method and the simulation method. The lecture method combines the photojournalism instructor or a guest (preferably a professional) with the traditional instructional materials of photographic prints, slides, films, and videotapes. Lectures should be structured with the audio-visual materials so that students will understand why and how a photographer acted given a specific set of circumstances. The student should also understand why and how the photograph was used in the newspaper. The simulation method can include in-class role playing games, complex environmental re-creations, ethics surveys, or interactive software on a computer. The fol1owing is a discussion of the various methods used to teach photojournalism ethics with an extended explanation of an interactive computer software program developed by the author.
 Physics , 2011, DOI: 10.1088/0264-9381/28/14/145012 Abstract: We consider the Post-Newtonian limit of massive Brans-Dicke theory and we make some notes about the Post-Newtonian limit of the case $\omega=0$. This case is dynamically equivalent to the metric $f(R)$ theory. It is known that this theory can be compatible with the solar system tests if Chameleon mechanism occurs. Also, it is known that this mechanism is because of the non-linearity in the field equations produced by the largeness of the local curvature relative to the background curvature. Thus, the linearization of the field equations breaks down. On the other hand we know that Chameleon mechanism exists when a coupling between the matter and the scalar field exists. In the Jordan frame of Brans-Dicke theory, we have not such a coupling. But in the Einstein frame this theory behaves like a Chameleon scalar field. By confining ourselves to the case $\omega=0$, we show that "Chameleon-like" behavior can exist also in the Jordan frame but it has an important difference compared with the Chameleon mechanism. Also we show that the conditions which lead to the existence of "Chameleon-like" mechanism are consistent with the conditions in the Post-Newtonian limit which correspond to a heavy scalar filed at the cosmological scale and a small effective cosmological constant. Thus, one can linearize field equations to the Post-Newtonian order and this linearization has not any contradiction with the existence of "Chameleon-like" behavior.
