Der „Homo alpinus“. Eine kurze Notiz zu Willy Hellpachs Versuch, die Existenz von Bergmenschen auf ein umweltpsychologisches Fundament zu stellen by Patrick Stoffel

“…Embedded in contemporary race theory, which he expanded to include elements of environmental psychology, he came to the conclusion that mountains, beyond the “racial origin” of their population, produce a soil phenotype due to the “abundance of things to cope with” that they offer in a very confined space: the Homo alpinus, being characterized by self-sufficiency and a rich imagination.…”

Mutual Investments Funds in Shares in Brazil : Incentives, Management and Convergence by Paulo Rogério Faustino Matos, Christiano Modesto Penna, Ana Balbina Gomes Silva

“…This article analy zes patterns of convergence in series of return of investment funds in shares in Brazil, from the use of the methodology of Phillips and Sul (2007). Unlike the theory of portfolios and in disagreement with the characteristics of this market -regulation, t ransparency, efficiency and informational transaction costs-, it shows a heterogeneous behavior, from the formation of four clubs with specific transition and composition dynamics. …”
