This group, which has long been seen and treated as a pariah of society, has gained fame in recent years and had his image reformulated in the media. This work, in a first moment, seeks to address the nerd profile, analyzing their history, characteristics and media representations in products as TV series and movies, to make a reflection about what means to be nerd currently. For this analysis, the authors Nugent (2008), Goffman (1988), Fernando and Rios (2001) and Bourdieu (1983) are used to identify the group's distinguishing characteristics, their stigmatization in society and its relationship with consumption and the media. Then, a discussion about the connection between communication and culture is aroused, using authors like Caune (2004), Thompson (2001), Schulman (2004) and Morley (1996), among others, to highlight the importance of cultural studies within the scope of this research. Production and consumption are intertwined when we look conveyed cultural products in mass media, so TV series, their classification, public relationship and the importance of the characters that make them up are analyzed as elements connecting product and audience. Jost (2012), Esquenazi (2010), Seger (2006), Davis (2001) and Field (2001) are used to explain the production processes of TV series and character creation, fundamentals to understand the success of an American TV show The Big Bang Theory, displayed on CBS (EUA) and Warner Channel (Brazil). After a detailed analyze of this sitcom's characters, the results of the research carried out for this job are presented. As methodology, a structured survey, with a quantitative and a qualitative approach was applied in a random sample of 600 person, with the purpose of investigate their consuming habits, favorite TV series, connection with characters, perceptions about The Big Bang Theory and their vision about consider themselves or be considered nerd by others. At the conclusion of this research, it is reported that the relationship between people and cultural products they consume is based on affect and identification with the plot and characters in the story. Regarding The Big Bang Theory series, different opinions are presented on the character stereotyping and narrative evolution. Finally, it's concluded that being a nerd, or be considered as well, nowadays it is still something that carries a lot of negativity for those who do not fall within the group, but becomes a empowering factor for who is included. This identity is constructed through the high consumption of cultural products aimed at establishing an emotional connection with these people and offering a projection of the narrative of their lives. / Esta pesquisa tem como objetivo investigar a relação das pessoas com a série televisiva The Big Bang Theory e sua percepção a respeito de se considerarem ou serem consideradas nerds.

Após uma análise detalha dos personagens destas sitcom, apresenta-se os resultados da pesquisa realizada para este trabalho. Como metodologia, um questionário estruturado, com abordagem quantitativa e qualitativa, foi aplicado em uma amostra aleatória de 600 pessoas, com o objetivo de investigar seus hábitos de consumo, séries favoritas, conexão com os personagens, percepções acerca da série The Big Bang Theory e sua visão sobre considerarem-se ou serem considerados nerds por outras pessoas. Na conclusão desta pesquisa, relata-se que a relação das pessoas com os produtos culturais que consomem é baseada por afetos e identificação com o enredo e personagens da história. Em relação à série The Big Bang Theory, opiniões diversas são apresentadas sobre a estereotipificação dos personagens e evolução da narrativa. Por fim, conclui-se que ser nerd, ou ser considerado assim, hoje em dia ainda é algo que carrega bastante negatividade para quem não se insere no grupo, mas se torna um fator de empoderamento para quem se inclui.

Mediatiserad religion i ramen av humor : En studie av den amerikanska sitcom-serien the Big Bang Theory / Mediatizied religion in a humour context : A study of the American sitcom-series the Big Bang Theory

Andersson Happe, Emma January 2015 (has links)
Since 2007 the American sitcom the Big Bang Theory has spread throughout the world. With its twenty million watchers it is one of the most popular sitcoms of our time. The starting point for this essay is that the humourus series with the more or less geeky main characters is more than just entertainment - it is a part of the mediatization of religion. This means that media is affecting the recipients’ view on religion in general and the personal religion. As we watch TV, we get socialized into how to act in our every day life. In this case, it is about religion depicted as entertainment. Through a film analysis of a number of selected scenes from the first three seasons of the series, this essay stresses the representation of the religious traditions Judaism, Christianity, Hinduism and religion in general. On the basis of etnocentrism, exitocism and a differentiation between religious praxis and religious beliefs my conclution is that Jews are portrayed in a very ”modern” and secular way, Christians are narrow-minded and quite stupid and Hindus are doing strange rituals and believe in very unreasonable phenomena. Religion in general is portrayed as something accepted but it should be rational and religous practice has its own time and place.

The Subtitler’s visibility management: a case study of WHV’s and YYeTs’s Chinese translations of The Big Bang Theory

Huang, Boyi 11 April 2019 (has links)
This thesis presents a study on the subtitler's visibility management as manifested by their subtitling approaches. The special textuality and the recent digitization of subtitling practices make the subtitler's visibility management through subtitling an issue that is rather distinctive from the translator's visibility in general. Previous studies that directly investigate subtitler's visibility tend to focus on subtitler's relatively restricted and/or linear social interactions, while relevant discussion that examines their non-linear social interactions such as subtitling is very rare. Almost no study has provided either a conceptualization of subtitler's visibility or a systematic analytical framework specifically for analysing the subtitler's visibility management through subtitling. In the current study, the author examines the subtitler's visibility management through subtitling by comparing WHV industrial subtitlers' and YYeTs fansubbers' subtitling approaches to The Big Bang Theory. Based on Nornes's (2007) notions of corrupt and abusive subtitling and Ortabasi's critiques on the lack of multimodality in these notions, it has been hypothesized that the two groups of subtitlers' approaches differ in two dimensions and three aspects of issues. Accordingly, an analytical framework is constructed to systematically interrogate the two groups of subtitlers' visibility management as reflected by their subtitling approaches: 1) comparing their subtitling approaches to the verbal and nonverbal issues identified in the represented dimension; 2) comparing their subtitling approaches to the technical issues identified in the representing dimension; 3) comparing and discussing how their relatively different approaches in the two dimensions demonstrate their different visibility management. The findings suggest that the ways in which WHV industrial subtitlers and YYeTs fansubbers manage their visibility differently are multifaceted and bidimensional. First, the industrial subtitlers tend to adopt a relatively corrupt approach and the fansubbers tend to adopt a relatively abusive approach in the represented dimension, while the relative differences between their approaches are more drastic in the verbal aspect than in the nonverbal aspect. Second, the above-found relative differences between the two groups of subtitlers' approaches are even more explicitly consistent in the technical aspect of the representing dimension. Third, in both dimensions, the industrial subtitlers gain less visibility through the relatively corrupt approach and the fansubbers acquire more visibility through the relatively abusive approach. More profoundly, by adopting the relatively corrupt approach, the industrial subtitlers perform gatekeepers in the represented dimension and adherents in the representing dimension; by using the relatively abusive approach, the fansubbers present themselves as educators in the represented dimension and as innovators in the representing dimension. Beyond these findings, this thesis also makes broader theoretical and methodological contributions. It has demonstrated how a nonbinary and generative conceptualization of the subtitler's visibility from a sociological perspective, hitherto never provided by previous discussions, can lead to more fruitful investigations on the subtitler's visibility management. This combination of Nornes's (2007) notions of corrupt and abusive subtitling and Ortabasi's (2007) critiques on them offers us a set of analytical tools for thoroughly investigating how subtitlers manage their visibility differently through subtitling.

Modeling the formation, evolution, and observation of first stars

Kulkarni, Mihir Sanjay January 2021 (has links)
Population III (Pop III) stars are the first generation stars forming after the big bang from primordial gas. This dissertation is focused on the various processes that suppress and delay the formation of Pop III stars in the universe and their implications for the observations. We studied the impacts of the Lyman-Werner (LW) radiation that dissociates molecular hydrogen, baryon-dark matter streaming velocity introduced at recombination, ionizing radiation from nearby galaxies, and a model for the composition of dark matter known as the fuzzy dark matter on the formation of Pop III stars. Firstly, we take a closer look at the critical halo mass (Mcrit) that is the typical minimum dark matter halo mass needed to host cold dense gas to form the first stars using cosmological hydrodynamical simulations. LW radiation that dissociates molecular hydrogen and the baryon-dark matter streaming velocity both delay the formation of Pop III stars by increasing the critical halo mass. We describe our simulation suite with varying levels of LW radiation and streaming velocity to provide a fit for Mcrit as a function of LW radiation, streaming velocity, and redshift which can be used in semi-analytic models of early galaxy formation to make predictions for observations. Secondly, we explore a possible mechanism for the formation of large clusters of Pop III stars: a nearby ionizing source that ionizes a late forming halo, delaying its collapse until the halo is sufficiently large enough that the core can self-shield and suffer runaway collapse. We use numerical simulations to examine the fragmentation of the gas near the runaway collapse using the simple estimates and sink particles to show that the number of fragments is generally small, at most a handful, and that the mass accretion rate on the fragments is of order 10⁻³ Msun/yr. This rate is sufficiently high enough that the descent on the main sequence (and hence the suppression of accretion) is delayed until the stellar masses are of order 100-1000 Msun, but not high enough to produce direct collapse black holes of mass ~ 10⁵ Msun. The resulting clusters are larger than those produced in minihalos but are still likely to fall short of being easily detectable in James Webb Space Telescope blind fields. Finally, we investigate the formation of the first stars and galaxies in a fuzzy dark matter cosmology. Fuzzy dark matter, made up of ultra-light axions of mass ~ 10⁻²² eV, is a proposed alternative to the standard cold dark matter to solve its apparent small-scale problems. Its large de Broglie wavelength, of the order of kpc, results in the suppression of small-scale matter power, thus delaying the formation of the first stars and galaxies to lower redshift in much more massive halos. Therefore, first stars can be used to put very strong constraints on the mass of the fuzzy dark matter. We describe our cosmological simulations that accurately evolve the fuzzy dark matter distribution to study the formation of the first stars and galaxies.
