Dimensionamento à punção em apoios internos de lajes protendidas sem aderência

Esta dissertação trata da punção em lajes protendidas com cordoalhas não aderentes, para pilares internos, calculadas através das normas ABNT NBR 6118:2007, ABNT NBR 6118:2014, EN 1992-1-1:2004 e ACI 318-11. Ao longo do trabalho, são apresentados dimensionamentos à punção através desses códigos a fim de se obter uma análise comparativa dos resultados. Além disso, são expostas três situações de provas de carga não destrutivas para punção, realizadas em lajes reais. Os casos, verificados a partir da comparação entre as quatro normas, servem de base para avaliações sobre o nível de segurança estrutural entre os dimensionamentos. Após as análises teóricas, conclui-se que, no geral, o EC2:2004 e a NBR 6118:2014 são os códigos que geram os resultados menos conservadores no cálculo das armaduras de punção. Já o ACI 318-11 e a NBR 6118:2007 obtêm os resultados mais conservadores para esse dimensionamento. Quando considerados os carregamentos máximos sem utilização de armadura de punção, a norma americana se destaca, obtendo valores comparáveis aos do EC2:2004 e da NBR 6118:2014. A NBR 6118:2007 resulta em dimensionamentos sempre mais conservadores.

A harder edge: reframing Brazil's power relation with Africa

Brazil's rapprochement with Africa during the last decade has been mostly explained as an attempt to improve political dialogue, raise economic interactions, and provide technical cooperation assistance. This article, however, argues that such framework does not sufficiently account for the use of Brazilian material resources in order to attain harder strategic goals towards the continent. By focusing on defense cooperation ties, it highlights an important niche in South-South relations that has also grown exponentially, with important consequences on how Brazil exerts power across the Atlantic.

Comportamento e perfil do consumidor de turismo de nichos

Tourism is one of the most important and current drivers of growth in an economy characterized by dynamism, diversity of supply and steady growth. This study aims at researching the behavior and consumer profile in tourism from a marketing perspective. In particular we address the niche tourism in specific contexts. Under an interdisciplinary perspective this work brings together inputs from the areas of marketing, tourism and local development. There will be a reflection on the subject (work in progress) and discussed avenues for future studies.

Consumer behavior and profile in cross border tourism destinations

Tourism is a phenomenon that moves millions of people around the world, taking as a major driver of the global economy. Such relevance is reflected in the proliferation of studies in the overall area known as tourism, under various perspectives and backgrounds. In the light of such multitude of insights our study aims at gaining a deeper understanding of customer profiling and behavior in cross-border tourism destinations. Previous studies conducted in such contexts suggest that cross-border regions (CBRs) are an attractive and desirable idea, yet requiring further theoretical and empirical research. The new configuration of many CBRs calls for a debate on issues concerning its development, raising up important dimensions, such as, organization and planning of common tourism destinations. There is still a gap in the understanding of destination management in CBRs and the customer profile and motivations. Overall this research aims at attaining a deeper understanding of the profile and behavior of consumers in tourism settings, addressing the predisposition for the destination. The study addresses the following research question: “What factors influence customer behavior and attitudes in a CBRs tourism destination?” To address our question we will take an interdisciplinary perspective bringing together inputs from marketing, tourism and local economics. When addressing consumer behavior in tourism previous studies considered the following constructs: involvement, place attachment, satisfaction and destination loyalty. In order to establish the causal relationships in our theoretical model, we intend to develop a predominant quantitative design, yet we plan to conduct exploratory interviews. In the analysis and discussion of results, we intend to use Structural Equation Modeling. It will further allow understanding how the constructs in the research model relate to each other in the specified context. Results are also expected to have managerial implications. Consequently our results may assist decision makers in developing their local policies.

An approach on place attachment, involvement and behavioural intentions in cross-border tourist regions

This study aims at gaining a deeper understanding of customer profiling and behaviour in cross-border tourism destinations. The study is developed under a niche marketing perspective. It is our view that niche marketing is not confined to the limits of national markets. Previous studies suggest that cross-border regions are an attractive notion, yet they require further theoretical and empirical research. There is still a gap in the understanding of destination management in cross-border regions and the customer profile and motivations. Overall this research attempts to produce a deeper understanding of the profile and behaviour of consumers in tourism settings, addressing the predisposition for the destination in specific contexts (cross-border tourism regions).

STRATEGIC DECISIONS OF FAMILY FIRMS ON CASH ACCUMULATION

ABSTRACTGiven the particular strengths, weaknesses, and peculiarities of family firms as well as the importance of liquidity in today’s marketplace, we analyze the distinct characteristics and strategies of family businesses related to the amount of cash a firm holds. We look beyond the traditional factors that influence decisions related to cash management to examine factors that are particularly important for family firms. Specifically, we outline the relevance of strategic decisions guided by family firms’ conservatism, flexibility, long-term view, and the active control that they have over family members. To our knowledge, no prior studies exist regarding family firms and their strategic adjustment of cash holding. Therefore, we investigate whether the ownership structure of the firm (through the presence of a controlling family) moderates decisions on cash holding. We found that family firms tend to accumulate cash for strategic reasons and as a result of their own idiosyncrasies. Thus, family firms can achieve optimal cash accumulation more efficiently than non-family firms.

The Interpretation of Verbal Probability Expressions Used in the IAS/IFRS: the auditors Rrgistered with the portuguese securities market commission

One of the main arguments in favour of the adoption and convergence with the international accounting standards published by the IASB (i.e. IAS/IFRS) is that these will allow comparability of financial reporting across countries. However, because these standards use verbal probability expressions (v.g. “probable”) when establishing the recognition and disclosure criteria for accounting elements, they require professional accountants to interpret and classify the probability of an outcome or event taking into account those terms and expressions and to best decide in terms of financial reporting. This paper reports part of a research we carried out on the interpretation of “in context” verbal probability expressions used in the IAS/IFRS by the auditors registered with the Portuguese Securities Market Commission, the Comissão do Mercado de Valores Mobiliários (CMVM). Our results provide support for the hypothesis that culture affects the CMVM registered auditors’ interpretation of verbal probability expressions through its influence on the accounting value (or attitude) of conservatism. Our results also suggest that there are significant differences in their interpretation of the term “probable”, which is consistent with literature in general. Since “probable” is the most frequent verbal probability expression used in the IAS/IFRS, this may have a negative impact on financial statements comparability.
