Chapter 7 describes the fundamental role of randomness in quantum mechanics, in generating the first biomolecules, and in biological evolution. Experiments testing the Einstein–Podolsky–Rosen paradox have demonstrated, via Bell’s inequalities, that no local hidden variable theory can provide a viable alternative to quantum mechanics, with its fundamental randomness built in. Randomness presumably plays an equally important role in the chemical assembly of a wide array of polymer molecules to be sampled for their ability to store genetic information and self-replicate, fueling the sort of abiogenesis assumed in the RNA world hypothesis of life’s beginnings. Evidence for random mutations in biological evolution, microevolution of both bacteria and antibodies and macroevolution of the species, is briefly reviewed. The importance of natural selection in guiding the adaptation of species to changing environments is emphasized. A speculative role of cosmological natural selection for black-hole fecundity in the evolution of universes is discussed.

This article examines the impact of institutional, financial, and economic development on firms’ access to finance in Latin America and Caribbean region. Based on firm- and country-level data from the World Bank databases, we employ an ordered logit model to understand the direct and moderating role of institutional, financial, and economic development in determining firms’ financial obstacles. The results show that older, larger, facing less competition and regulation burden, foreign owned, and affiliated firms report lower obstacles to finance. Second, better macro-fundamentals help to lessen the level of obstacles substantially. Third, the role of institutions in promoting firms’ inclusive finance is quite different to the role of financial development and economic growth. JEL classification: E02; G10; O16; P48

This essay analyzes how, marginalized by national literatures and threatened by the rise of regional mass media in the 1980s and 1990s, northern Mexican border authors and their texts consistently concerned themselves with the temporalities of representation——particularly in literary narrative. Through their treatment of temporal issues, these writers directed themselves toward a local, transnational reading community and enacted a critical regionalism that articulates local signification within larger processes reshaping the role of literature in contemporary Latin America.

Alice Lentz offers a brief view of the role of the Americas Fund for Independent Universities (AFIU) in relation to significant initiatives in various Latin American countries. In a region where the function and development of private higher education institutions is especially important, the focus of the AFIU's activities is on private universities' ability to provide trained business leaders with the skills necessary to meet the challenges of enterprise growth in these developing economies. She mentions in particular the strengthening of financing capabilities within the university, and the evolution of three-way partnerships among business corporations, AFIU, and universities in Latin America.
