Motivations to participate in international trade fairs: the Portuguese experience

Motivations/barriers to participate in ITF

Participate (or not) in international trade fairs? Decision factors of Portuguese managers

Portugal is a small economy, with an open domestic market that needs competitive exporters to prosper. Trade fairs are an international promotion tool that can be used by firms when considering export development and expansion. This study identifies and evaluates the critical factors that influenced the decision making process of Portuguese SME’s (Small and Medium-Sized Enterprises) managers to participate (or not) in international trade fairs. The results indicate that the firm’s critical decisions factors to select an international trade fair were value for money and the stand (location, typology and size)

Language and trade: the (new) route of portuguese in the 21st century

Globalisation has eliminated frontiers and in the case of Europe helped the crossing of borders and changed forever the concept of social (and I would also say individual) geography: the rest of the world is out there; we can pretend not to see it, but we cannot avoid it. Moreover, Europe is undergoing a serious crisis, also economic, and new markets and business partners are welcome. In this context, cultural bonds like a common language can open new investment paths and give rise to successful stories. In this paper we intend to present an example of how low linguistic distance can lead to good business, even if a) in the internationalization process of the companies’ language is often forgotten as a management element and b) consumers of language products (like User Guides) are also not stimulating investment in language by the companies. Through the results of 2 studies carried out in 2010 and 2011 we will show how a pluricentric language like Portuguese is managed in multinational companies (MC) and Small and medium Enterprises (SMEs). The second study is based on an online survey questioning the effectiveness, efficiency and general quality of User Guides and the reaction of consumers to language. Results show that although playing a role in the internationalization process of companies in the same linguistic space, language is opportunistically used. On the other hand, Portuguese and Brazilian consumers show a very functional perception of the Portuguese language...

The Greatest lover: a post-colonial rewriting of My Fair Lady

INTRODUCTION The popular Hong Kong comedy, The Greatest Lover, re-incarnates one of the most popular western musicals, My Fair Lady. OBJECTIVES 1. To find out in what major ways My Fair Lady was rewritten as the Hong Kong Cantonese movie, Gungzi Docing (The Greatest Lover). 2. To find out the socio-political, socio-linguistic, and gender ideology behind the rewriting. METHODOLOGY 1. To note the similarity of the themes for both works – a creator falling in love with his/her creation, and class prejudice and cross-class romance. 2. To note how the times of The Greatest Lover differ from that of My Fair Lady. 3. To note how the main characters in The Greatest Lover differ from My Fair Lady in terms of profession, gender, etc. 4. To note how the plot of The Greatest Lover differs from that of My Fair Lady. 5. To note how focus on language in The Greatest Lover compares with that in My Fair Lady. 6. To discuss the ideological implications of the differences noted above, e.g. women in Hong Kong today have much higher status than women in Victorian England; the conflict between local Hong Kong people and both legal and illegal immigrants from Mainland China is even more serious than that between the British upper middle class and the lower class during the Victorian period. 7. Andre Lefevere (1992) argues that translation and adaptation are rewriting informed and influenced by the rewriter’s ideology, among other things. 8. Both Aline Remael (1995) and Patrick Cattrysse (1992) think that film adaptation is a kind of translation. 9. Sirkkus Aaltonen (2000) argues that drama translation mirrors the ideologies of the target society. CONCLUSION 1. The Greatest Lover projects local cultural significance onto My Fair Lady by helping us to appreciate an important Western work of art through the Hong Kong Cantonese perspective. 2. Broader issues in translation and intercultural studies are also considered.

True and fair view: um conceito de geometria variável

De acordo com o parágrafo 46 da estrutura concetual do SNC as demonstrações financeiras devem mostrar uma imagem verdadeira e apropriada, ou apresentar apropriadamente, a posição financeira, o desempenho e as alterações da posição financeira de uma entidade. Todavia, a estrutura concetual do SNC não interpreta diretamente tais conceitos, situação que se pode refletir na qualidade do reporting financeiro apresentado e divulgado. O referencial contabilístico português apresenta, como equivalentes, as noções de true and fair view, presentfairly, fairly reflect ou fair reflection, e silenciando toda a polémica envolvente às expressões apresentadas. Com efeito, a primeira expressão é identificada, com a União Europeia, onde a apresentação e divulgação da informação financeira é baseada num conjunto de princípios — principies — based standards — e pressupõe o exercício de um julgamento, enquanto que as três expressões seguintes traduzem o standard de reporting financeiro, para os Estados Unidos, tendo subjacente a abordagem designado por — rule based standards — A não abordagem do SNC levou-nos a refletir sobre o assunto apresentado, apresentando uma análise multifacetada do conceito.

Energy and delay trade-off of the GTS allocation mechanism in IEEE 802.15.4 for wireless sensor networks

The IEEE 802.15.4 protocol proposes a flexible communication solution for Low-Rate Wireless Personal Area Networks (LR-WPAN) including wireless sensor networks (WSNs). It presents the advantage to fit different requirements of potential applications by adequately setting its parameters. When in beaconenabled mode, the protocol can provide timeliness guarantees by using its Guaranteed Time Slot (GTS) mechanism. However, power-efficiency and timeliness guarantees are often two antagonistic requirements in wireless sensor networks. The purpose of this paper is to analyze and propose a methodology for setting the relevant parameters of IEEE 802.15.4-compliant WSNs that takes into account a proper trade-off between power-efficiency and delay bound guarantees. First, we propose two accurate models of service curves for a GTS allocation as a function of the IEEE 802.15.4 parameters, using Network Calculus formalism. We then evaluate the delay bound guaranteed by a GTS allocation and express it as a function of the duty cycle. Based on the relation between the delay requirement and the duty cycle, we propose a power-efficient superframe selection method that simultaneously reduces power consumption and enables meeting the delay requirements of real-time flows allocating GTSs. The results of this work may pave the way for a powerefficient management of the GTS mechanism in an IEEE 802.15.4 cluster.

The determinants of trade credit: a study of portuguese industrial companies

Despite the relevance of trade credit as a source of business financing, the topic is far from being considered exhausted, especially because there is no general and integrated theory explaining the causes and consequences of trade credit.Our research aims to contribute towards the literature that studies the determinants for granting and receiving trade credit. In this sequence, the present study seeks to empirically test some theories about the reasons why companies grant and receive commercial credit. For this purpose we apply a fixed effect model to a panel of 11 040 Portuguese industrial companies, of which 360 are large companies and the majority 10 680 are Small and Medium Enterprises (SME) for the period between 2003 and 2009. We conclude that large companies (with greater access to credit market) serve as financial intermediaries to their clients with less access to finance. In addition, it was observed that the supplier companies use trade credit as a legal means of price discrimination. Finally, financially constrained enterprises, especially in times of financial crisis, use commercial credit as an alternative source of funding, endorsing the hypothesis of substitution between trade credit and bank credit.

An optimal boundary fair scheduling

Nowadays, many real-time operating systems discretize the time relying on a system time unit. To take this behavior into account, real-time scheduling algorithms must adopt a discrete-time model in which both timing requirements of tasks and their time allocations have to be integer multiples of the system time unit. That is, tasks cannot be executed for less than one time unit, which implies that they always have to achieve a minimum amount of work before they can be preempted. Assuming such a discrete-time model, the authors of Zhu et al. (Proceedings of the 24th IEEE international real-time systems symposium (RTSS 2003), 2003, J Parallel Distrib Comput 71(10):1411–1425, 2011) proposed an efficient “boundary fair” algorithm (named BF) and proved its optimality for the scheduling of periodic tasks while achieving full system utilization. However, BF cannot handle sporadic tasks due to their inherent irregular and unpredictable job release patterns. In this paper, we propose an optimal boundary-fair scheduling algorithm for sporadic tasks (named BF TeX ), which follows the same principle as BF by making scheduling decisions only at the job arrival times and (expected) task deadlines. This new algorithm was implemented in Linux and we show through experiments conducted upon a multicore machine that BF TeX outperforms the state-of-the-art discrete-time optimal scheduler (PD TeX ), benefiting from much less scheduling overheads. Furthermore, it appears from these experimental results that BF TeX is barely dependent on the length of the system time unit while PD TeX —the only other existing solution for the scheduling of sporadic tasks in discrete-time systems—sees its number of preemptions, migrations and the time spent to take scheduling decisions increasing linearly when improving the time resolution of the system.

Strategic trade policy and signaling costs with differentiated goods

We consider a trade policy model, where the costs of the home firm are private information but can be signaled through the output levels of the firm to a foreign competitor and a home policymaker. We compute the separating equilibrium and the Bayesian Nash equilibrium, and we compare the subsidies, firms’ expected profits and home government’s welfare in both equilibria, for different values of the own price effect parameter.
