Determinantes Nacionais e Setoriais da Estrutura de Capital na América Latina
This study identified the role of the national environment (the Macroeconomy, Financial Development and
Institutional Quality) and industry characteristics (Munificence, Dynamism, Concentration, Life Cycle,
Technological Efficiency Dispersion, Product Quality Dispersion, Customer Bargaining Power and Supplier
Bargaining Power) on debt of 612 listed companies from 7 Latin American countries (Argentina, Brazil, Chile,
Colombia, Mexico, Peru and Venezuela). For comparison purposes, the analysis is also extended to 847 U.S.
companies. The period of study is 1996-2009 and the analysis employed a Hierarchical Linear Model, which
controls the effects according to the level of the variables (country, industry, time and firm). The results suggest
that Financial Development eases access to external funds and Institutional Quality is negatively related to firm
Leverage. The research also finds evidence that institutional quality can promote asymmetrical development
between stock markets and credit markets

CUBES: a UV spectrograph for the future
In spite of the advent of extremely large telescopes in the UV/optical/NIR range, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Cassegrain U-Band Efficient Spectrograph (CUBES) has been designed to provide high-efficiency (>40%) observations in the near UV (305-400 nm requirement, 300-420 nm goal) at a spectral resolving power of R>20,000, although a lower-resolution, sky-limited mode of R ~ 7,000 is also planned. CUBES will offer new possibilities in many fields of astrophysics, providing access to key lines of stellar spectra: a tremendous diversity of iron-peak and heavy elements, lighter elements (in particular Beryllium) and light-element molecules (CO, CN, OH), as well as Balmer lines and the Balmer jump (particularly important for young stellar objects). The UV range is also critical in extragalactic studies: the circumgalactic medium of distant galaxies, the contribution of different types of sources to the cosmic UV background, the measurement of H2 and primordial Deuterium in a regime of relatively transparent intergalactic medium, and follow-up of explosive transients. The CUBES project completed a Phase A conceptual design in June 2021 and has now entered the Phase B dedicated to detailed design and construction. First science operations are planned for 2028. In this paper, we briefly describe the CUBES project development and goals, the main science cases, the instrument design and the project organization and management
