O presente trabalho tem por objetivo contribuir com a historiografia literária sul-rio-grandense e seu sistema literário, através do resgate da obra impressa por Francisco Xavier Ferreira em sua tipografia e dos registros literários da primeira metade do século XIX publicados no jornal O Noticiador. Ao coletar e analisar esses dados, pode-se divulgar melhor os autores, poemas e outros textos pouco conhecidos da região sul do Rio Grande do Sul. Também é possível certificar a veracidade dos dados biográficos referentes aos autores que publicaram nesse periódico. Reunir os dados esparsos sobre Francisco Xavier Ferreira e seus contemporâneos permite igualmente conhecer melhor a história da imprensa no Rio Grande do Sul, já que esse fundou a primeira tipografia e o primeiro jornal da cidade de Rio Grande. Além dos impressos de 1831 e 1834, o conteúdo literário existente no jornal O Noticiador, publicado de 1831 a 1836, é a fonte primordial para o para entender a inserção da literatura no contexto intelectual da época. Desta forma, busca-se entender a literatura produzida na década de 1830, bem como resgatar o contexto literário da época em que foi produzida.

Integrated marketing communication incorporates both customer and non-customer stakeholder groups. While the literature commonly refers to this distinction as marketing communication and corporate communication, respectively, and practitioners accept the need for these roles, this study aims to explore the student perspective. US-based research suggests that students are more interested in marketing communication activities such as promotion that target customer stakeholders, and less interested in corporate communication activities that target non-customer stakeholders including employees, investors, and government (Bowen, 2003). The findings of this study match its US counterpart, and present implications for both the education and practice of marketing communication

Stockmarket regulators in Australia, Canada and the United States have all issued recent challenges to listed companies on their disclosure practices, questioning in many cases what has been long standing practice. Financial public relations counsellors are constantly called up to advise on the communication consequences of difference disclosure strategies. This paper will explore the challenges, faced by a group of financial communicators within seven Australia listed companies, in setting and enacting disclosure polices for the organisations. It will identify hey issues involved in communicating within a regulated environment, as well as address the implications of new technology for future practice.

The purpose of this article is to examine how a consumer’s weight control beliefs (WCB), a female advertising model’s body size (slim or large) and product type influence consumer evaluations and consumer body perceptions. The study uses an experiment of 371 consumers. The design of the experiment was a 2 (weight control belief: internal, external) X 2 (model size: larger sized, slim) X 2 (product type: weight controlling, non-weight controlling) between-participants factorial design. Results reveal two key contributions. First, larger sized models result in consumers feeling less pressure from society to be thin, viewing their actual shape as slimmer relative to viewing a slim model and wanting a thinner ideal body shape. Slim models result in the opposite effects. Second this research reveals a boundary condition for the extent to which endorser–product congruency theory can be generalized to endorsers of a larger body size. Results indicate that consumer WCB may be a useful variable to consider when marketers consider the use of larger models in advertising.

Log-linear and maximum-margin models are two commonly-used methods in supervised machine learning, and are frequently used in structured prediction problems. Efficient learning of parameters in these models is therefore an important problem, and becomes a key factor when learning from very large data sets. This paper describes exponentiated gradient (EG) algorithms for training such models, where EG updates are applied to the convex dual of either the log-linear or max-margin objective function; the dual in both the log-linear and max-margin cases corresponds to minimizing a convex function with simplex constraints. We study both batch and online variants of the algorithm, and provide rates of convergence for both cases. In the max-margin case, O(1/ε) EG updates are required to reach a given accuracy ε in the dual; in contrast, for log-linear models only O(log(1/ε)) updates are required. For both the max-margin and log-linear cases, our bounds suggest that the online EG algorithm requires a factor of n less computation to reach a desired accuracy than the batch EG algorithm, where n is the number of training examples. Our experiments confirm that the online algorithms are much faster than the batch algorithms in practice. We describe how the EG updates factor in a convenient way for structured prediction problems, allowing the algorithms to be efficiently applied to problems such as sequence learning or natural language parsing. We perform extensive evaluation of the algorithms, comparing them to L-BFGS and stochastic gradient descent for log-linear models, and to SVM-Struct for max-margin models. The algorithms are applied to a multi-class problem as well as to a more complex large-scale parsing task. In all these settings, the EG algorithms presented here outperform the other methods.

Crisis holds the potential for profound change in organizations and industries. The past 50 years of crisis management highlight key shifts in crisis practice, creating opportunities for multiple theories and research tracks. Defining crises such as Tylenol, Exxon Valdez, and September 11 terrorist attacks have influenced or challenged the principles of best practice of crisis communication in public relations. This study traces the development of crisis process and practice by identifying shifts in crisis research and models and mapping these against key management theories and practices. The findings define three crisis domains: crisis planning, building and testing predictive models, and mapping and measuring external environmental influences. These crisis domains mirror but lag the evolution of management theory, suggesting challenges for researchers to reshape the research agenda to close the gap and lead the next stage of development in the field of crisis communication for effective organizational outcomes.
