A broadcast on a graph G=(V,E) is a function f : V → {0, ..., diam(G)} that assigns an integer value to each vertex such that, for each v ∈ V , f (v) ≤ e(v), the eccentricity of v. The broadcast number of a graph is the minimum value of Σv∈V f (v) among all broadcasts f with the property that for each vertex x of V, f (v) ≥ d(x, v) for some vertex v having positive f (v). This number is bounded above by both the radius of the graph and its domination number. Graphs for which the broadcast number is equal to the domination number are called 1-cap graphs. We investigate and characterize a class of 1-cap trees. / Graduate

The usual graph parameters related to independent and dominating sets can be adapted to broadcasts on graphs. We examine some possible definitions for an inde- pendent broadcast. We determine the minimum maximal and the maximum broad- cast weight for all our independence parameters on both paths and grids. For graphs in general, we examine the relationships between these broadcast independence pa- rameters and the existing minimum and maximum minimal broadcast domination weight (or cost). We also determine upper and lower bounds for maximum boundary independent broadcasts and a new upper bound for hearing independent broadcasts. / Graduate

Thesis (M.S.)--Boston University

This thesis is a comparative study into contemporary mainstream cooking programmes on British, French and German television, which explores how food and cooking are represented. Since food is an expression of identity (Corti 2012; German 2011; Montanari 2006; Scholliers 2001) this study argues that food representation on television is influenced by national culture. Cooking programmes have become increasingly popular in many countries, and recent years have further seen the emergence of a variety of formats, the characteristics of which also influence how food and cooking are represented. This study applies a multi-method research approach which explores the influence of country of production and format on food representation. While a qualitative grounded theory analysis focuses on the key functions and characteristics of the food, the cooking and the chef, a quantitative analysis explores the food groups represented in the programmes to establish a sense of healthiness. The quantitative analysis has found that 'fruit and vegetables' and 'non-dairy protein' are the largest food groups in the majority of programmes across all countries of production and all formats. The qualitative analysis highlighted that country of production is a determining factor on how food and cooking functions are represented, as the three countries feature considerable differences in these areas. The data further revealed three kinds of chef, as well as a mixed chef scenario each using one of three instruction styles. The analysis showed that the format determines the type of chef presented as well as their instruction style. It further confirms that some programmes are highly instructional, whereas others focus more on celebrity and entertainment. This study thus contributes to our understanding of food representation in contemporary British, French and German cooking programmes and its cultural significance.

A \textit{broadcast} on a connected graph $G$ with vertex set $V(G)$ is a function $f:V(G)\rightarrow \{0, 1, ..., \text{diam}(G)\}$ such that $f(v)\leq e(v)$, where $e(v)$ denotes the eccentricity of $v$. A vertex $v$ is said to be \textit{broadcasting} if $f(v)>0$. The \textit{cost} of $f$ is $\sigma(f)=\sum_{v\in V(G)}f(v)$, or the sum of the strengths of the broadcasts on the set of broadcasting vertices $V_f^+=\{v\in V(G)\,:\,f(v)>0\}$. A vertex $u$ \textit{hears} $f$ from $v\in V_f^+$ if $d_G(u, v)\leq f(v)$. The broadcast $f$ is \textit{hearing independent} if no broadcasting vertex hears another. If, in addition, any vertex $u$ that hears $f$ from multiple broadcasting vertices satisfies $f(v)\leq d_G(u, v)$ for all $v\in V_f^+$, the broadcast is said to be \textit{boundary independent.} The minimum cost of a maximal boundary independent broadcast on $G$, called the \textit{lower bn-independence number}, is denoted $i_{bn}(G)$. The \textit{lower h-independence number} $i_h(G)$ is defined analogously for hearing independent broadcasts. We prove that $i_{bn}(G)\leq i_h(G)$ for all graphs $G$, and show that $i_h(G)/i_{bn}(G)$ is bounded, finding classes of graphs for which the two parameters are equal. For both parameters, we show that the lower bn-independence number (h-independence number) of an arbitrary connected graph $G$ equals the minimum lower bn-independence number (h-independence number) among those of its spanning trees. We further study the maximum cost of boundary independent broadcasts, denoted $\alpha_{bn}(G)$. We show $\alpha_{bn}(G)$ can be bounded in terms of the independence number $\alpha(G)$, and prove that the maximum bn-independent broadcast problem is NP-hard by a reduction from the independent set problem to an instance of the maximum bn-independent broadcast problem. With particular interest in caterpillars, we investigate bounds on $\alpha_{bn}(T)$ when $T$ is a tree in terms of its order and the number of vertices of degree at least 3, known as the \textit{branch vertices} of $T$. We conclude by describing a polynomial-time algorithm to determine $\alpha_{bn}(T)$ for a given tree $T$. / Graduate

The purpose of this research was to examine gender issues in contemporary sermons. My sample consists of sermons delivered on BBC Radio 4 as part of acts of worship broadcast during 1993-4 which were examined to analyse how language, gender and power intersect to produce these discourses. In order to contextualize this material, chapter one focuses on the history of the sermon and its institutionalisation. Chapter two analyses the preachers’ use of generic terms and their use of the second person plural mode of address. In chapter three, I examine the gendered illustrations offered in the sermon sample in order to investigate how they contribute to create alienating and exclusionary discourses. Chapter four deals with the ways in which self-disclosure and the use of personal experience provide a means by which knowledge can be assimilated and transferred to others as well as acting as an inclusive mechanism in preaching. In chapter five, I demonstrate that metaphors have the potential to function as an inclusive device but that this influence may be negated if the gender content of the metaphor conveys gender-biases. Chapter six centres on the form and structure of the sermons as a way of considering the issue of a participatory address. The conclusion focuses on the way in which aspects of the notions of inclusive language intersect with the ways in which authority is traditionally defined. This thesis demonstrates that contemporary broadcast sermons do not endeavour to reflect the demands for inclusive language or less authoritarian discourses which have been made by feminists and advocated by most denominations in the Christian churches

Para tanto, a pesquisa se dividiu em uma primeira abordagem histórica do desenvolvimento do jornalismo audiovisual no Brasil, para, a partir dessa compreensão histórica, buscar entender os procedimentos atuais na inserção de música nos telejornais englobados, sempre tendo como ponto de partida a práxis interna da produção desses telejornais / Abstract: The purpose of this dissertation is to analyse the usage of music in four TV news programs daily broadcasted nationwide by Rede Globo. By looking into their opennings and headnews as well as the sound tracks used during the main news reports, the research sheds some light on the editorial procedures utilized to decide on the most appropriate sound track to accompany the news. The dissertation presents a historical research on the development of the audiovisual journalism in Brazil which served as a starting point for understanding the usage of music in the production of TV broadcasted news / Mestrado / Mestre em Multimeios

Teve por objetivo analisar algumas formas de ocorrência da intertextualidade temática, por meio do estudo da centração tópica, e da polifonia, a partir do entendimento dos processos de produção e edição do discurso reportado, no sub-gênero telejornal, um dos principais integrantes da variada gama de gêneros da TV. O objeto da análise é constituído por telejornais veiculados no horário nobre da televisão brasileira: o jornal Cultura Noite, da TV Cultura e o Jornal Nacional, da TV Globo. Mais especificamente, o universo da pesquisa é formado por cinco edições de cada um dos telejornais, das respectivas emissoras, exibidos entre os dias 07/05/07 e 11/05/07. A questão norteadora indaga em que medida os procedimentos de definição do foco relevante da notícia, bem como a mobilização das vozes sociais enunciadas para a construção do gênero telejornal, estão ligados aos modelos público e privado de televisão. Em princípio, partimos da hipótese de que as respectivas funções sociais de cada uma dessas emissoras tivessem uma influência mais significativa, no modo pelo qual ocorre o estabelecimento de relações intertextuais, de natureza temática, e polifônicas. A análise dos telejornais, tanto no seu recorte sincrônico, por meio do estudo comparativo de tópicos abordados em edições do mesmo dia, quanto no recorte diacrônico, por meio do estudo da enunciação polifônica, bem como da organização tópica, ao longo da semana, possibilita concluir que tais interferências ocorrem com maior evidência no nível macro-estrutural destes gêneros. É, portanto, no nível textual discursivo que se encontra a força geradora dos diferentes modos de se constituir gêneros telejornalísticos que, entendidos como prática social, encontram-se relacionados aos seus contextos de produção, não sendo deles, porém, de todo dependentes para construírem uma identidade. / Abstract: This paper has its axis in the field of textual linguistics, having its basis also set on theories of the social sciences, specifically in the subfields of social history and communication sociology. It aims at assessing a variety of different possible occurrences of theme intertext relationships through a deeper look onto concepts as topic centration and polyphony, by the means of comprehending the processes of producing and editing the reported discourse in the TV News broadcasting genre. The object of such analysis embraces specifically prime time Brazilian tv news: TV Cultura's jornal Cultura Noite and TV Globo's Jornal Nacional. This study comprises five subsequent presentations of each of the object programs, namely those broadcasted from May 07th, 07 to May 11th, 07. This study revolves around and issue: the connection between the private and public established standards of tv producing and both the process of definition of what's relevant for the news and the mobilization of the enunciated social voices. At first we hypothesized each of these tv stations' social roles would significantly influence the entanglements of how intertext relationships - thematic by nature - are developed, as well as the polyphonic relationships. Analyzing the tv news programs - either synchronically, through a comparative assessment of the issues presented in their respective editions on single different days; or diachronically, by the means of studying their distinct polyphonic enunciation and topic ordering during the entire week - one can conclude such interferences occur more evidently at the level of the macro-structure of these genres. It's therefore within the discursive textual level that the resides the boosting power that generates the most diverse tv news genres. And as far as their social roles are concerned, such genres can be said to be related to their respective production contexts, although the genres are not thoroughly dependent on their social roles when it comes to building their own identity. / Doutorado / Doutor em Linguística
