Sendo assim, o foco central da ação investigativa desta pesquisa está no processo de didatização de um gênero de texto (cuja prática social fomenta a interdisciplinaridade) que se dá, nesta pesquisa, por meio de um dispositivo de ensino chamado de Projetos Didáticos de Gênero (doravante, PDG) que viabiliza o ensino de língua através de gêneros de texto, desenvolvendo as capacidades de linguagem dos alunos. Já a demanda pela interdisciplinaridade conduz ao estudo do gênero de texto ‘artigo midiático de divulgação científica’ (doravante, artigo MDC). Assim, este trabalho apresenta a aplicação de um PDG com enfoque no gênero artigo MDC com vistas a desenvolver as capacidades de linguagem dos alunos e a propiciar a aprendizagem interdisciplinar. Os principais aportes teóricos que sustentam as ações desta pesquisa situam-se nos estudos do Interacionismo sociodiscursivo (ISD), de Bronckart (2009; 2012; 2013), além dos estudos sobre as capacidades de linguagem, realizados por Dolz e Schneuwly (2011) e Cristóvão e Stutz (2011; 2013), sobre as Sequências Didáticas, também de Dolz e Schneuwly (2011); sobre os Projetos de Letramento, de Kleiman (1995; 1999; 2000; 2007; 2008) e sobre a divulgação cientifica e midiática de Charaudeau (2008; 2009; 2010). O processo metodológico pelo qual se realiza esta investigação consiste na pesquisa-ação e compõe-se de ações que vão desde o planejamento do PDG e sua aplicação em sala de aula à elaboração da ferramenta de análise de dados. A elaboração do PDG resultou em um projeto interdisciplinar chamado de ‘Jovens cientistas’ aplicado a uma turma de 2º ano do ensino médio da rede pública estadual do município de Sapucaia do Sul-RS e contou com a colaboração da professora de Biologia, a fim de estabelecer a interdisciplinaridade. A análise dos dados obtidos indica que a didatização de um gênero como os artigos MDC, por meio de um dispositivo de ensino de língua como o PDG, pode de fato desenvolver as capacidades de linguagem dos alunos e contribuir para a construção do aprendizado interdisciplinar em sala de aula. / The need for the continued development of teaching methods of mother tongue able to transform students' language practices and promote interdisciplinary relations of knowledge, according to advocating official documents as the PCNs and OCEM, are so Overall, the social context in which originate the motivations for developing this research. Thus, the central focus of the investigative action of this research is on didactization process of a text genre (whose social practice fosters interdisciplinary) that occurs in this research using a teaching device called Genre Didactical Projects (henceforth GDP) that enables the language of instruction through text genres, developing the students' language skills. However, demand for interdisciplinarity leads to text genre study ‘Media Articles of Science Communication'. This work presents the application of a GDP focusing on gender Article MDC in order to develop students' language skills and to foster interdisciplinary learning. The main theoretical contributions that sustain the actions of this research are located in Socio-Discursive Interacionism studies (SDI) of Bronckart (2009; 2012; 2013), in addition to studies on language skills, conducted by Dolz and Schneuwly (2011) and Cristóvão; Stutz (2011; 2013), on Teaching sequences, also Dolz and Schneuwly (2011); on literacy projects, Kleiman (1995; 1999; 2000; 2007; 2008) and the scientific and media disclosure from Charaudeau (2008; 2009; 2010). The methodological process by which it accomplishes this research consists in action research and consists of actions ranging from planning the GDP and its application in the classroom to the development of data analysis tool. The preparation of the GDP resulted in an interdisciplinary project called 'Young scientists' applied to a class of 2nd year of high school in a public school in the city of Sapucaia do Sul and with the collaboration of a Biology teacher in order to establish interdisciplinary.The data analysis indicates that the didactization of a genre as the Media Articles of Science Communication, through a language teaching device as the PDG, can indeed develop students' language skills and contribute to the construction of interdisciplinary learning in the classroom of class.

The main research of the study was: How is integrated communication applied in the UKZN AIDS Programme at Westville Campus? The following six subsidiary research questions were formulated to address this topic:  How is communication aligned with the strategic focus in the UKZN AIDS Programme?  How consistent are messages and media used in and outside the UKZN AIDS Programme?  What is the status of infrastructure for integration within the UKZN AIDS Programme?  What is the status of internal stakeholder orientation and differentiation in the UKZN AIDS Programme?  What are the mechanisms put in place to coordinate communication efforts and action within the UKZN AIDS Programme?  What is the status of free flow of information within the UKZN AIDS Programme? A qualitative research design was conducted using field and survey research. These two research methods may be used for descriptive, exploratory, and explanatory research (Mouton 1996:232). Descriptive and exploratory field and survey research were used to ascertain the integrated communication applied in the UKZN AIDS Programme. Data was collected from sixteen UKZN AIDS Programme employees and eight students using semi-structured focus group and in-depth interviews respectively. Data collected was analysed using thematic analysis a technique that involves identifying, analysing and reporting in detail patterns or themes within data.The study found that the UKZN AIDS Programme focuses mostly on the University as its main stakeholder. Therefore, there is little emphasis on employees and students. Besides, the study revealed that there is poor alignment of the programme’s communication strategy with the programme’s strategy. To achieve the UKZN AIDS Programmes’ strategic objectives and mission, there is need to reassess the efforts of the programme and re-strategise. Findings on the consistency of messages and media in the UKZN AIDS Programme reveal that all communications are managed by senior employees and consistent in terms of programme identity by using the university identity, and website messages. The status of the consistency of messages and media in the programme can be improved if a comprehensive approach can be used in communicating internal messages. Findings on the consistency of messages and media in external communication show that the programme tries to communicate different prevention messages using channels favoured by students. However, channels such as drama and peer educators have weaknesses that need to be addressed in addition to employing diverse communication channels. Findings show that some of the messages communicated are relevant in the sense that they address students’ sexual risk behaviour while others are not as they are off tangent such that they address issues students are not concerned about. In addition, findings show that peer educators were not exemplary in their work while drama programmes did not allow students to actively participate in the prevention activities. On infrastructure for integration, the study found that there is infrastructure and several prospects for information sharing in the programme created by information technology though not fully explored. With regards the free flow and sharing of information, the study established that the required systems for communication exist but not adequately utilised. Findings on the co-ordination of communication efforts and actions to promote integrated communication show flaws. Departments in the programme function in silos due to lack of cross-functional planning. The integrated communication conceptual framework used in the study was useful in making the study successfully ascertain integrated communication applied by the UKZN AIDS Programme. The conceptual framework can therefore be used to underpin any research topic on health integrated communication. / Communication Science / MA (Communication) / 1 online resource (v, 222 leaves)

In this thesis, we study the tradeoff of average delay with average service cost and average utility for both continuous time and discrete time single server queueing models without and with admission control. The continuous time and discrete time queueing models that we consider are motivated by cross-layer models for point-to-point links with random packet arrivals and fading at slow and fast time scales. Our studies are motivated by the need to optimally tradeoff the average delay of the packets (a network layer performance measure) with the average service cost of transmitting the packets, e.g. the average power required for transmission (a physical layer performance measure) under a lower bound constraint on the average throughput, in various point-to-point communication scenarios. The tradeoff problems are studied for a class of monotone and stationary scheduling policies and under the assumption that the service cost rate and utility rate are respectively convex and concave functions of the service rate and arrival rate. We also consider the problem of optimally trading off the average delay and average error rate of randomly arriving message symbols which are transmitted over a noisy point-to-point link, in which case the service cost function is non-convex. The solutions to the tradeoff problems that we address in the thesis are asymptotic in nature, and are similar in spirit to the Berry-Gallager asymptotic bounds. It is intuitive that to keep a queue stable under a lower bound constraint on the average utility a minimum number of customers have to be served per unit time. This in turn implies that queue stability requires a minimum average service cost expenditure. In the thesis we obtain an asymptotic characterization of the minimum average delay for monotone stationary policies subject to an upper bound constraint on the average service cost and a lower bound constraint on the average utility, in the asymptotic regime where the average service cost constraint is made arbitrarily close to the above minimum average service cost. In the thesis, we obtain asymptotic lower bounds on the minimum average delay for the cases for which lower bounds were previously not known. The asymptotic characterization of the minimum average delay for monotone stationary policies, for both continuous time and discrete time models, is obtained via geometric bounds on the stationary probability of the queue length, in the above asymptotic regime. The restriction to monotone stationary policies enables us to obtain an intuitive explanation for the behaviour of the asymptotic lower bounds using the above geometric bounds on the stationary probability distribution of the queue length. The geometric bounds on the stationary probability of the queue length also lead to a partial asymptotic characterization of the structure of any optimal monotone stationary policy, in the above asymptotic regime, which was not available in previous work. Furthermore, the geometric bounds on the stationary probability can be extended to analyse the tradeoff problem in other scenarios, such as for other continuous time queueing models, multiple user communication models, queueing models with service time control, and queueing models with general holding costs. Usually, queueing models with integer valued queue evolution, are approximated by queueing models with real valued queue evolution and strictly convex service cost functions for analytical tractability. Using the asymptotic bounds, we show that for some cases the average delay does not grow to infinity in the asymptotic regime, although the approximate model suggests that the average delay does grow to infinity. In other cases where the average delay does grow to infinity in the asymptotic regime, our results illustrate that the tradeoff behaviour of the approximate model is different from that of the original integer valued queueing model unless the service cost function is modelled as the piecewise linear lower convex envelope of the service cost function for the original model.
