Understanding Indian Rhetoric on Its Own Terms: Using a Vedic Key to Unlock the Vedic Paradigm

Melfi, Anne 17 December 2015 (has links)
Our “terministic screens,” learned attitudes and assumptions that screen what we see, render much data invisible and thus hinder the study of South Asian rhetorics. I hypothesized that by using two terms central to the Vedic worldview—Ṛta and levels of speech theory—as a terministic key, a touchstone, I could better identify and study Vedic rhetoric on its own terms and understand its modes and methods. This study finds that together these terms give insight into the Vedic paradigm as a whole. Chapter two explores these terms, noting that beyond audible speech and silent speech-in-thought theorized in Western rhetoric, Vedic empirical study finds two deeper levels: Paṣyantī, sensing an idea as a gestalt, and Parā, the transcendental source of speech, and includes methods for using the full range and power of speech, an embodied literacy. String theory of quantum physics echoes the Vedic cosmology of speech and its power, and illustrates the principle that drives the Vedic rhetorical modes and methods, which the next chapters explore: chapter three, the nondiscursive rhetorics of mantra, chapter four, the didactic rhetorics of dance and of the guru-disciple dynamic, and chapter five, collaborative debate toward truth, and cosmic citizenship in the governing assembly. All are driven not by persuasion but attunement with Ṛta—Truth/all the laws of nature/Brahman—an eloquence that embodies cosmic harmony. Being vs. seeming, truth vs. truthiness: Could an alternate approach to current practice advance our understanding and teaching of rhetoric and raise the level of our civic discourse?

Effects of Receiver Locus of Control and Interaction Involvement on the Interpretation of Service Complaints

Reed, William 05 1900 (has links)
This thesis examined how receivers who vary in Interaction Involvement and Locus of Control (LOC) might differ in their interpretations of service complaints. Locus of control was measured using Rotter's (1966) LOC scale, while Interaction Involvement was measured with Cegala's (1984) Interaction Involvement measure, including a separate assessment of the effects for each sub-scale. Individuals were assigned to four groups based on their Interaction Involvement and LOC scores. The groups were compared with one-another for differences in how complaints were interpreted. Four complaint categories and a corresponding scale were developed to measure these differences. The categories were Subject, Goal, Opportunity, and Accountability. Interaction Involvement was expected to affect how receivers interpret the subject and goal of a complaint, while LOC was predicted to affect understanding of the opportunity and accountability aspects. Two research questions explored possible relationships between the complaint categories and the independent variables for individuals within each group. The study's four hypotheses were not supported, although some evidence was found for a significant relationship between receiver Interaction Involvement and perceived complainant Opportunity, for External LOC individuals only.

As classes sociais na comunicação: sentidos teóricos do conceito / Social classes in communication: theoretical meanings of the concept.

Grohmann, Rafael do Nascimento 03 November 2016 (has links)
O objetivo desta tese é compreender o lugar e a relevância do conceito de classe social no campo da comunicação e quais sentidos teóricos o conceito apresenta na área. Como ponto de partida, apresentamos mapeamento e análise de teses, dissertações e artigos de congressos (Compós, Comunicon e Intercom) entre os anos de 2010 e 2014. Em geral, podemos observar fragilidades teórico-metodológicas com relação aos conceitos de classes e comunicação, ocorrendo muitas vezes uma naturalização do conceito de classe. Além disso, em alguns casos, não há relação mais explícita com a perspectiva comunicacional ou vigilância epistemológica entre instâncias e fases da pesquisa. Em alguma medida, salvo exceções, os sentidos teóricos das classes são banalizados ou pouco aprofundados, não considerando questões de lutas e conflitos, com as desigualdades sendo transformadas em meras diferenças. Então, partindo de uma perspectiva marxista, discutimos implicações teórico-metodológicas das teorias de classes, em suas diferentes abordagens e procuramos traçar uma trajetória do conceito de classes nos estudos de comunicação. A partir dos sentidos do conceito no corpus, esboçamos três eixos teóricos, a saber: a) estudos de recepção; b) eixo discursivo; c) eixo da produção, de modo a englobar a complexidade dos processos comunicacionais. Propomos, então, pensar em midiatização, mediação e circulação das classes (e suas lutas), sendo a circulação a categoria mais ampla, envolvendo a circulação comunicacional e do próprio capital. A partir dessas categorias, podemos compreender as lutas de classes nas relações de comunicação. / The aim of this thesis is to understand the place and the relevance of the concept of social class in communication research and which theoretical senses the concept presents in the studies. As starting point, we present an analysis of PhD and Master thesis, and conference papers of Compós, Comunicon and Intercom between 2010 and 2014. In general, we can observe theoretical and methodological weakness in classes and communication concepts. Moreover, in some cases, there is no explicit relationship with communicational perspective or an epistemological reflexivity between research instances and phases. To some extent, with some exceptions, theoretical meanings of concept are trivialized and not considering issues of struggles and conflicts, with inequalities transformed into mere differences. Then, from a Marxist approach, we discuss theoretical and methodological implications of class theories, in their different approaches and try to draw a way of the concept of classes in communication studies. From the meanings of concept, then, we outlined three theoretical areas: a) reception studies; b) discoursive axis; c) production axis, in order to encompass the complexity of communication processes. We propose, then, to think of mediatization, mediation and circulation of classes (and struggles of classes), with circulation as broadest category, involving communicational and capital circulation. From these categorias, we can understand class struggles in communicational relations.

Percepção e impacto no fotojornalismo. Fotografia e comunicação

Queiroga, Bruna Alves de 21 September 2012 (has links)
Este trabalho trata de uma pesquisa de recepção baseada na fenomenologia do Princípio da Razão Durante. Ele teve como objetivo observar a relação entre o observador e a fotografia, e se pergunta: o que ocorre nesse processo? De um lado, ele considera que a comunicação acontece apenas no receptor, que ela é individual e intransponível, dependendo de certa abertura para o mundo, de certa percepção. De outro, que na fotografia o que se destaca é sua parte vívida, que também depende da percepção. No início, o trabalho ressalta as características híbridas da fotografia, como algo entre arte e documentação. O recorte aqui é a fotografia jornalística, que levanta questões para se pensar o que é a fotografia em geral. No segundo capítulo, faz-se uma aproximação entre a teoria e o Acontecimento comunicacional, a saber, a comunicação propriamente dita. Por último, o trabalho apresenta o relato obtido como resultado da observação realizada na exposição de fotojornalismo World Press Photo. / This work deals with a research based on the phenomenology of the Principle of Reason During. He\'s aimed to the observation of the relationship between the viewer and the photograph, and asks: what happens in this process? On one hand, he believes that communication happens only at the receiver, it is individual and impassable, depending on certain openness to the world, in a sense. On the other, he believes that in the picture what stands out is its vivid parts, that also depends on perception. At first, the work highlights the hybrid features photography as something between art and documentation. Detached here is the journalistic photography, posing questions to think about what is photography in general. In the second chapter, is made an approximation between theory and communicational Event, namely the communication itself. Finally, the paper presents a report obtained as a result of the observation made in photojournalism exhibition of World Press Photo.

Secure Communication by Coherence Modulation at the Photon Counting Level

Unknown Date (has links)
Secure communication is a topic of great importance. The goal of our research reported here is to develop a scheme of secure communication system using coherence modulation at the photon counting level. When operated at the photon counting level, coherence modulation can provide quantifiably secure binary transmission between two entities, security being based on the nonclonability of photons. The objectives of the research are as follows: Show that interferometer-based coherence modulation can provide physics guaranteed secure binary transmission where each bit is associated with a countable number of photons. Review the operation of conventional high-light-level coherence modulation communication and then show, by means of example, that through the reduction of light intensities to photon-counting levels the system can be made secure. Analyze a particular attack on the system to demonstrate the quantifiability of the scheme’s security. Implement a version of the BB84 quantum key distribution protocol by slightly modifying our scheme in order to achieve a greater security. Identify a variety of issues related to hardware and the challenges of implementing our scheme in the real world. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

O receptor produtor e o produtor receptor: o uso de novas ferramentas de comunicação no telejornalismo latino-americano. Uma análise Brasil e México / The producer receptor and the receiver producer: the use of new communication tools in Latin American TV journalism. An analysis of Brazil and Mexico

Cavalcante, Juliane 04 May 2011 (has links)
A presente pesquisa propõe uma discussão sobre o impacto que o uso de novas ferramentas de comunicação pode provocar no telejornalismo e nos modos de produzir de seus profissionais, bem como estes últimos têm lidado e enxergam essas modificações. Tais ferramentas permitiram que os antes chamados receptores aqui compreendidos como os indivíduos que assistiam ao telejornal e não tinham nenhuma relação com os seus modos de produção se tornassem também produtores de conteúdo. Discutimos um novo modelo de comunicação, que obriga as teorias que dão conta deste fenômeno a dar um passo adiante e construir novos modelos para explicar esse processo. Este novo fenômeno também exige que os jornalistas produtores de telejornais lidem com uma nova realidade e buscamos neste estudo compreender se estão preparados para este desafio. / The following research proposes a discussion on how the use of new communication tools can influence TV journalism and on the way it is produced, as well as on how the producers have been dealing and seeing these changes. Such tools allowed the former known receptors here understood as those individuals who watch TV newscasts and didnt have any relation with its ways of production to also become content producers. We discussed a new communication model, which makes former theories dealing with this phenomenon to take a step further and construct new models to explain this process. This new phenomenon also demands that the TV newscasts journalist producers deal with a new reality and we intended in this study to comprehend if they are prepared for this challenge.

Communication on digital media, on the other hand, is two way, in which the individual not only has the possibility to send their own messages, bus also respond to those they receive. Therefore, new digital media changed radically the communication environment, making it important to review the main communication theories seeking to identify those that can still explain multimedia and transmedia communication. In this dissertation, we mapped these main communication theories and detailed how digital and transmedia communication works. With four case studies we illustrated how communication happens today and looked for those communications theories that still fits in this scenario / A partir de um breve panorama das principais teorias da comunicação percebemos que a maioria das teorias que perduram até hoje foram pensadas entre 1930 e 1960 baseadas nos meios de comunicação de massa; meios esses que preveem uma comunicação assimétrica e de um para muitos. A comunicação nos meios digitais, por outro lado, é uma via de mão dupla, por meio da qual o indivíduo não apenas passou a ter a possibilidade de transmitir suas próprias mensagens, mas também responder àquelas que recebe. Dessa forma, as novas mídias digitais trouxeram uma grande mudança no ambiente comunicacional, o que torna importante a revisão das principais teorias da comunicação com o objetivo de identificar aquelas que ainda conseguem explicar a comunicação multimeios e transmidiática. Nessa dissertação mapeamos as principais teorias da comunicação e detalhamos a comunicação digital e transmidiática. Através quatro de estudos de caso ilustramos a comunicação hoje e buscamos as principais teorias da comunicação que ainda se encaixam nesse cenário

"Vi säger ju att vi har bett om ursäkt hur många gånger som helst" : En kvantitativ innehållsanalys av organisationer risk- och krishantering på sociala medier

Sundström, Emma, Lönnkvist, Victoria January 2019 (has links)
The purpose of the essay is to find out how crisis communication takes shape on different social media. The essay deals with both organizations' risk and crisis management on Facebook and Instagram. A risk is defined in the essay as anything that could possibly lead to a crisis that could adversely affect an organization. A crisis is defined here as an unpredictable event that threatens key expectations of stakeholders. To answer the purpose, the essay authors have used the following main and sub-questions; How does the selected organizations' management of Facebook and Instagram look from a crisis communication perspective? What are the differences or similarities in risk and crisis management on Facebook and Instagram? How do organizations use Coombs different crisis management strategies on Facebook and Instagram? In what way, if so, does the tonality differ on the different platforms? The theoretical framework begins with a chapter that summarizes previous research and leads to the research gap. One theory that has been used in the study is Situational Crisis CommunicationTheory, where Timothy Coomb's seven strategies on crisis management are used throughout the essay. Other theories that have also been used are Social Mediated Crisis Communication, medialization and media logic. The method that has been used is quantitative content analysis where ten different organizations' feeds on both Facebook and Instagram have been analyzed. The units that were examined were classified as risk or crisis messages that were published during the period 2017-01-01 until 2018-11-20. The result shows that the organizations' management of Facebook and Instagram before, during and after a crisis looks different depending on the platform. There are similarities but also many interesting differences. One thing that differentiates the platforms is that it is more forgiving on Facebook and it is more common for the organizations to try to blame someone else on Instagram. The organizations also tend to be less personal on Instagram than on Facebook. The result also shows that Coomb's crisis management strategies are used in all found units and that the tone on Facebook tends to be more positive than it is on Instagram. An interesting discovery was that despite Instagram's visual logic, the platform was not used for that purpose when an organization goes through a crisis.
