José Afonso da Silva Jr.,Eduardo Queiroga
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.
The scaling limit of Fomin's identity for two paths in the plane  [PDF]
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.
The Teaching of Photojournalism Ethics: Help from the Computer  [PDF]
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.
Notes on the post-Newtonian limit of massive Brans-Dicke theory  [PDF]
Mahmood Roshan,Fatimah Shojai
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.
The crossroad of photojournalism A encruzilhada do fotojornalismo  [cached]
Simonetta Persichetti
Discursos Fotográficos , 2006,
Abstract: This article features the crisis of photojournalism, sparked in the eighties, and the academic debates aroused by this discussion. It points out the key issues and offer suggestions on how to cope with new information: the new photojournalism, the spectacularization of the news and photography, citizenship journalism and the flood of images produced by amateur digital equipments, which steadily spread throughout the media. Este artigo trata da crise do fotojornalismo, desencadeada a partir dos anos 1980, e os debates acadêmicos que permeiam esta discuss o. Questiona e sugere como enfrentar as novas formas de informa o: o novo fotojornalismo, a espetaculariza o da notícia e da fotografia, o jornalismo cidad o e a enxurrada de imagens produzidas pelas cameras digitais amadoras, que aos poucos v o ocupando espa os na mídia.
Tensions within Identity: Notes on How Criminalized Women Negotiate Identity through Addiction
Jennifer M. Kilty
Aporia : The Nursing Journal , 2011,
Abstract: Drawing on conceptualizations of a loss of personal power versus empowerment, criminalized womenin Canada engage two seemingly opposed discourses to explain their substance use. When feeling a lossof control/power participants constructed substance use as a disease, and when feeling in control of theirsubstance use they described becoming substance free as based on an empowered choice to use/quit using.This article explores the connection between choice/disease discourses and correctional treatment discoursesthrough an examination of women’s narratives about identity management and negotiation related tosubstance use. Based on 22 life history interviews with formerly incarcerated women and four social workerswho assist criminalized women as they transition from prison to the community, this research suggests thatcriminalized women construct a distinct drug using or ‘addict’ identity that they separate from their ‘true’ orcore conceptualization of self.

The Study of the Continuum Limit of the Supersymmetric Ward-Takahashi Identity for N=1 Super Yang-Mills Theory  [PDF]
A. Feo
Physics , 2003,
Abstract: The one-loop corrections to the supersymmetric Ward-Takahashi identity (WTi) are investigated in the off-shell regime in the Wilson formulation of the discretized N=1 Super Yang-Mills (SYM) theory. The study of the continuum limit as well as the renormalization procedure for the supercurrent are presented.
Criteria for newsworthiness and photojournalism Critérios de noticiabilidade e o fotojornalismo
Ivan Luiz Giacomelli
Discursos Fotográficos , 2008,
Abstract: This article reports on a survey aimed at checking, on a preliminary basis, the influence of the criteria of newsworthiness in making photojournalism, as well as if photojournalism influences the choice and selection of facts that will be news in the newspapers the next morning. Included in this study is a brief report on the historical evolution of both the journalism as the photojournalism, added by concepts of newsworthiness in both areas. In closing, it empirically checks the influence of the criteria for newsworthiness of photojournalism in journalism. Este artigo é um levantamento destinado a verificar, de forma preliminar, a influência dos critérios de noticiabilidade no fazer fotojornalístico, bem como se o fotojornalismo influencia na escolha e sele o dos fatos ser o notícia nos jornais do dia seguinte. Integra este estudo um breve relato histórico sobre a evolu o tanto do jornalismo quanto do fotojornalismo, seguido de conceitos de noticiabilidade nas duas áreas. Por fim, verifica empiricamente a influência dos critérios de noticiabilidade do fotojornalismo no jornalismo.
