Although Brazil imported more African slaves than any other country in the Americas, knowledge of the accounting and taxation of slave-related transactions in Brazil is under-developed. We explore Portuguese-language documents showing how accounting and taxation were implicated in maintaining slavery in Brazil in the eighteenth and nineteenth centuries. The study presents examples of key documents involving slaves (such as inventory lists, rental agreements, insurance policies, and receipts) and explains how slave-related transactions were recorded and taxed. We enable important comparisons to be drawn with the accounting and taxation of slaves in the USA and British West Indies.

This study considers the Certified Public Accountants (CPA) partners of the audit firms as the core producers of these knowledge-based organisations and investigates the effects of audit firm-level of CPA partners’ experience in audit quality. Audit quality was measured through the audit clients’ earnings quality. The main findings suggested that the audit firm-level of CPA partners’ general experience is positively associated with audit quality. Also, the audit firm-level of CPA partners’ experience acquired with prior audit firms significantly improves audit quality. Concerning the effects of audit firm-level of CPA partners’ experience acquired in the current audit firm in audit quality, results were statistically insignificant. Finally, we found that changes in audit firm-level of CPA partners’ general experience also influence audit quality. We verified that the more positive the change in the audit firm stock of CPA partners’ general experience, the higher is audit quality. We interpret this finding as revealing that the year-to-year changes in audit firm’s stock of CPA partners’ general experience is the mechanism allowing these firms to achieve and maintain the critical mass of this resource and reach higher performance levels. We further showed that our main results were not driven by the engagement partner experience.

Stents são estruturas entrançadas utilizadas no tratamento de doenças cardiovasculares, uma vez que previnem ou impedem a constrição do fluxo sanguíneo. A sua forma tubular é essencial para que consiga atingir a sua finalidade e manter o normal fluxo sanguíneo nos vasos sanguíneos. Neste trabalho foram desenvolvidos stents fibrosos entrançados, à base de poliéster (PES), poliamida (PA) e polipropileno (PP). Além disso, as propriedades mecânicas, que são influenciadas pelo ângulo de entrançamento e o diâmetro do mandril, foram testadas e discutidas. Este trabalho mostra que os stents fibrosos apresentam propriedades mecânicas adequadas e elevado potencial de mercado
