Qual o valor do auto-interesse?

The article critically reviews past and current justifications for the theoretical use of the behavioral assumption of self-interest, explanatory, normative, representational and critical, focusing on the critical function. This latter emerges from an incursion into the modern history of ideas and may be shown still to fertilize a number of contemporary economic approaches.

The pre-history of cryoscopy: what was done before raoult?

Cryoscopy is considered one of the foundations of the modern theory of solutions and of physical chemistry. This paper shows in order the first regularities pointed out by several scientists on the subject, in the first chapter of its birth as a scientific discipline. The study is focused on the identification of the different steps that helped, first qualitatively and then quantitatively, to adjust the different classes of possible solutions, including those that formed hydrates, to a basic formulation that the French scientist François-Marie Raoult would later generalize in the law that bears his name.

Discovering "os ianques do sul": towards an entangled Luso-Hispanic history of Latin America

The article reconstructs the largely forgotten role of key Brazilian intellectuals in the Latins-versus-Anglo-Saxons debates that developed around 1898, emphasizing the embeddedness of their thinking in the transnational crossings of men and ideas within South America. It thus challenges the common depiction of late-nineteenth-century Latin Americanism as a purely Spanish American phenomenon and of the United States as its major catalyst, allowing a more nuanced understanding of this movement' s nature.

The 1623 Plan for Global Governance: the obscure history of its reception

Abstract In the present article we analyze the characteristics and the reception of the first plan for global governance, the New Cyneas by Émeric Crucé. With this goal in mind, we examine the history of its readings and the possible influence on the Duke of Sully's project for European confederation, the case most often cited by historians of ideas. Our analysis takes into consideration the 17th century reception, the scant dissemination of the work and the possible causes of its limited impact. Our conclusions support, on the one hand, the novelty of Crucé's principal ideas, and on the other, their limited impact over the time with the exception of the period surrounding the creation of the League of Nations.

Emerging Latin America

This paper is specially dedicated to the students of management of the world. After outlining the historical, demographic, and physical aspects of Latin America, the authors establish and use a framework to describe and explain the modern economic, social, and political development of this region. The paper is firmly grounded on the historical dimensions of contemporary Latin America. Its background is the context of an exceptionally fast-moving global economy.

Modern cancer epidemiological research: genetic polymorphisms and environment

Individual cancer susceptibility seems to be related to factors such as changes in oncogenes and tumor suppressor genes expression, and differences in the action of metabolic enzymes and DNA repair regulated by specific genes. Epidemiological studies on genetic polymorphisms of human xenobiotics metabolizing enzymes and cancer have revealed low relative risks. Research considering genetic polymorphisms prevalence jointly with environmental exposures could be relevant for a better understanding of cancer etiology and the mechanisms of carcinogenesis and also for new insights on cancer prognosis. This study reviews the approaches of molecular epidemiology in cancer research, stressing case-control and cohort designs involving genetic polymorphisms, and factors that could introduce bias and confounding in these studies. Similarly to classical epidemiological research, genetic polymorphisms requires considering aspects of precision and accuracy in the study design.

Modern epidemiology and its discontents

The goal of this article is to present a snapshot of an ongoing debate within epidemiology, pitching opposing sides in the struggle to define the path it should follow in the years to come. The debate among epidemiologists in the mid-90s pitted those who defended the idea that epidemiology should necessarily deal with a wide context against those who believed that science and public health are better served by focusing on the individual level. Ian Hacking’s concept of styles of reasoning was used as a theoretical tool. The literature was reviewed using a core set of articles as an entry point, seeking articles that cited them, and then back-tracking the citations of the resulting set in the Scopus database. The main arguments are presented according to levels (ontological, epistemological, axiological and pragmatic), in order to show an even deeper disagreement, in the very conception of science and its relation to social issues and public policy.
