Innovation and entrepreneurship as strategies for success among Cuban-based firms in the late years of the transatlantic slave trade
This article examines how Cuban-based firms and entrepreneurs circumvented ever- increasing risks in the illegal slave trade. The article sheds light to this question by analyzing new qualitative information of 65 Cuban-based firms against the Slavevoyages database. Our findings indicate that Cuban-based firms were entrepreneurial as they exploited the opportunities arising from the volatility of the slave trade by: (a) internalizing networks of agents which allowed the rapid diffusion of information, (b) diversifying trading goods and expanding the number of partnerships to reduce transaction costs and risk, and (c) adopting technological innovations that modified the design and use of vessels
Soilâstrain compatibility: the key to effective use of arbuscular mycorrhizal inoculants?
Consistency of response to arbuscular mycorrhizal (AM) inoculation is required for efficient use of AM fungi in plant production. Here, we found that the response triggered in plants by an AM strain depends on the properties of the soil where it is introduced. Two data sets from 130 different experiments assessing the outcome of a total of 548 replicated single inoculation trials conducted either in soils with a history of (1) high input agriculture (HIA; 343 replicated trials) or (2) in more pristine soils from coffee plantations (CA; 205 replicated trials) were examined. Plant response to inoculation with different AM strains in CA soils planted with coffee was related to soil properties associated with soil types. The strains Glomus fasciculatum-like and Glomus etunicatum-like were particularly performant in soil relatively rich in nutrients and organic matter. Paraglomus occultum and Glomus mosseae-like performed best in relatively poor soils, and G. mosseae and Glomus manihotis did best in soils of medium fertility. Acaulospora scrobiculata, Diversispora spurca, G. mosseae-like, G. mosseae and P. occultum stimulated coffee growth best in Chromic, Eutric Alluvial Cambisol, G. fasciculatum-like and G. etunicatum-like in Calcaric Cambisol and G. manihotis, in Chromic, Eutric Cambisols. Acaulospora scrobiculata and Diversispora spurca strains performed best in Chromic Alisols and Rodic Ferralsols. There was no significant relationship between plant response to AM fungal strains and soil properties in the HIA soil data set, may be due to variation induced by the use of different host plant species and to modification of soil properties by a history of intensive production. Consideration of the performance of AM fungal strains in target soil environments may well be the key for efficient management of the AM symbiosis in plant production
An interactive installation of African music and the Trans-Atlantic slave trade
This paper introduces Afrobits, an interactive installation about African music and the Trans-Atlantic slave trade. Its main aim is to bring to light invisible stories hidden behind geographic epistemologies. The installation highlights the contribution that African cultures had on the tangible and intangible cultural heritage of the world, such as popular music. Although it covers diverse countries, we focused on the Americas, placing emphasis on Latin-America as the biopolitical space that enabled the integration of native cultures with African peoples. As this project involved web scientists, graphic designers, historians, digital humanists and artists, we also discuss the benefits of interdisciplinary research; contributions from University researchers for the development of storytelling projects for the Cultural Heritage sector; and the implementation of complex technologies and research methods
