A wide variety of traditional wooden boats and small ships can still be seen in use and being built on the mainland of Tanzania and the island of Zanzibar. This paper compares different accounts in the literature with observations made in 2012, and documents in detail the various stages of building wooden dhows on the beaches of Zanzibar.  相似文献

Few subjects have been more passionately discussed recently than the question of whether the invasion force in AD 43 landed in Kent or on the south coast or simultaneously in both areas. Recently Professor Frere and Professor Fulford joined forces to produce a series of arguments, each independently, supporting a landing in Kent. It is argued here that while archaeological or strategic considerations do not exclude either theory, some of the new 'evidence'– especially Frere's and Fulford's logistical and linguistic arguments – is demonstrably incorrect. Furthermore, the Kent hypothesis relies on the assumption of an unmentioned far–distance embassy and other non–straightforward interpretations of our main textual source, Cassius Dio. It is, however, not the aim of this paper to replace one one–sided hypothesis by another, but to point out the dangers of dogma.  相似文献

We use the case of Chile to analyze the effectiveness of a spatially blind employment relief program (hereafter referred to as the LPE program) established by the Chilean government and implemented during the COVID-19 pandemic. Chile is an interesting case because on the one hand its nonpharmaceutical interventions were spatially driven by health indicators based on small geographical areas; hence, producing sizeable regional and temporal variation of the local conditions induced by the COVID-19 pandemic. On the other hand, the LPE program was designed and implemented nationally without distinction of local labor market or pandemic conditions, and each firm could decide whether to enroll in the program. By exploiting the spatial-temporal variation of exogenously imposed lockdowns and using a difference-in-differences panel data framework, we find that the LPE program was only effective for a group of regions in the country but, more importantly, that the LPE program was less effective during lockdowns. Moreover, the requirements of the LPE program were vague and did not target specific populations or entities. Consequently, our results suggest that women, informal and small firm workers, and most economic sectors throughout the country were less able to take advantage of the benefits of this program.  相似文献
