In this article, we discuss ellipsis as an interactive strategy by analysing the author’s textchat corpus and the VOICE corpus of English as a Lingua Franca. It is found that there were fewer repetitions in the textchat data, and this is explained as a consequence of the textchat mode. Textchat contributions are preserved as long as the chat is active or has been saved, and therefore users can scroll through and review the discussion, compared to the more fleeting nature of oral conversation. As a result, repetition is less necessary. The frequency of other functions identified could be attributed to the topic of discourse. Discussions involve much ellipsis used to develop discourse, although some were self-presentations with repetition used to confirm details. Back-channel support and comments were often low because speakers instead used forms like yeah as supportive utterances.

In this work, I will discuss the integral role that myth has in society and then, after presenting several examples of this thesis, I will examine how the integral nature of myth lends itself to certain societal abuses. These abuses often result in unjust social constructs that eventually become attributed to the myth. I would like to proceed in defense of myth; that is, that these constructs are not to be attributed to the myths themselves, rather, society has taken myth and applied it to suit its purposes, ignoring the context in which the myths originated. Hopefully this will raise society's current attitudes toward myth to a level of respect, and will also help to clear myth of its reputation as the origin of injustice and domination.

We estimate and test two alternative functional forms, which have been used in the growth literature, representing the aggregate production function for a panel of countries: the model of Mankiw, Romer and Weil (Quarterly Journal of Economics, 1992), and a mincerian formulation of schooling-returns to skills. Estimation is performed using instrumental-variable techniques, and both functional forms are confronted using a Box-Cox test, since human capital inputs enter in levels in the mincerian specification and in logs in the extended neoclassical growth model.

This paper investigates which properties money-demand functions have to satisfy to be consistent with multidimensional extensions of Lucasí(2000) versions of the Sidrauski (1967) and the shopping-time models. We also investigate how such classes of models relate to each other regarding the rationalization of money demands. We conclude that money demand functions rationalizable by the shoppingtime model are always rationalizable by the Sidrauski model, but that the converse is not true. The log-log money demand with an interest-rate elasticity greater than or equal to one and the semi-log money demand are counterexamples.

O objetivo dessa dissertação foi investigar o processo de formação do Arranjo Produtivo Local (APL) de estanho em São João del-Rei - A7 Estanho, particularizando suas contribuições para o desenvolvimento local do município. O trabalho foi conduzido mediante uma discussão teórica sobre a situação das micro e pequenas empresas no Brasil, sobre a importância econômica e social dos arranjos produtivos locais, seus impactos no desenvolvimento regional e/ou local, principalmente de municípios sem infra-estrutura para atrair grandes empresas, e sobre políticas públicas que estão em andamento e que se voltam para o fomento desse tipo de aglomerado. Foram realizadas cerca de quatorze entrevistas no município de São João del-Rei: seis integrantes da Associação, uma funcionária, dois representantes das principais instituições parceiras, um representante do governo local e quatro membros da sociedade civil, que possuíam informações relevantes sobre a A7. O método empregado no tratamento dos dados foi a análise de conteúdo. Como resultados, no que diz respeito à análise dos programas que deram origem e/ou sustentação ao aglomerado, verificou-se que dois programas foram mais contundentes em suas contribuições à Associação: o Programa Empreender, da Federaminas, que permitiu a união dos empresários em torno de um objetivo comum, e o Projeto Via Design, do Sebrae, que possibilitou uma série de vantagens ao grupo, solidificando-o no mercado. No que se refere à participação dos diversos atores (membros da A7, poder público, instituições parceiras, sociedade civil) na construção do APL, pode-se perceber que o nível de atuação e comprometimento variava de acordo com as motivações pessoais, cargos ou funções formais exercidas e grau de relacionamento com a Associação. As contribuições ao desenvolvimento local do município, geradas pelo arranjo produtivo, foram enumeradas como geração de emprego e renda, ainda de forma incipiente, mas com possibilidades de crescimento futuro, e divulgação do turismo e cultura sãojoanense.

We estimate and test two alternative functional forms representing the aggregate production function for a panel of countries: the extended neoclassical growth model, and a mincerian formulation of schooling-returns to skills. Estimation is performed using instrumentalvariable techniques, and both functional forms are confronted using a Box-Cox test, since human capital inputs enter in levels in the mincerian specification and in logs in the extended neoclassical growth model. Our evidence rejects the extended neoclassical growth model in favor of the mincerian specification, with an estimated capital share of about 42%, a marginal return to education of about 7.5% per year, and an estimated productivity growth of about 1.4% per year. Differences in productivity cannot be disregarded as an explanation of why output per worker varies so much across countries: a variance decomposition exercise shows that productivity alone explains 54% of the variation in output per worker across countries.
