The Myth of Maria and the imagining of sexual trafficking in Brazil

Based upon the contradictory definitions of the crime, the Brazilian movement against trafficking in persons situates itself as a “struggle against modern slavery.” Within this moralistic context, the movement has frequently utilized invented statistics and apocalyptic declarations regarding trafficking in order to achieve greater “advocacy value” among members of the Brazilian public. A key component of this discursive formation has been the creation and promulgation of a mythological view of a “typical” trafficking victim’s experience: what we call “The Myth of Maria, an exemplary trafficking victim.” The present article seeks to follow the history of the Myth of Maria, developing an initial chronology mapped out and analyzed by Adriana Piscitelli in 2004 and extending this into the post-2006 period when Brazil established its first national policies and plans to combat trafficking in persons. We then analyze how the myth ignores many of the realities revealed by the past decade of ethnographic research into trafficking in Brazil. Finally, we conclude with a structuralist hypothesis (drawn from the field of feminist anthropology) regarding the Myth’s continuing unabated popularity among almost all actors in the political field of anti-trafficking policy.     

On trafficking survivors: biolegitimacy and multiplications of life

Dialectical Anthropology - Human trafficking has become a key site for intervention in global politics. Although anti-trafficking claims to mobilize resources for the combat against structural...     

Fritz Jahr: the invention of bioethics and beyond

Since the discovery of his work in 1997, Fritz Jahr (1895-1953) has slowly become recognized as the author of the term and concept of bioethics. Jahr's ideas on bioethics were partly different from those shaped by Van Rensselaer Potter in the 1970s and, therefore, might be helpful for the further reform and broadening of modern bioethics. In this article, the authors elucidate ideas from lesser-known works by Jahr, especially those considering animal protection and teaching.     

On the biogenesis of the myelin sheath: cognate polarized trafficking pathways in oligodendrocytes

Oligodendrocytes, the myelinating cells of the central nervous system, are capable of transporting vast quantities of proteins and of lipids, in particular galactosphingolipids, to the myelin sheath. The sheath is continuous with the plasma membrane of the oligodendrocyte, but the composition of both membrane domains differs substantially. Given its high glycosphingolipid and cholesterol content the myelin sheath bears similarity to the lipid composition of the apical domain of a polarized cell. The question thus arises whether myelin components, like typical apical membrane proteins are transported by an apical-like trafficking mechanism to the sheath, involving a 'raft'-mediated mechanism. Indeed, the evidence indicates the presence of cognate apical and basolateral pathways in oligodendrocytes. However, all major myelin proteins do not participate in this pathway, and remarkably apical-like trafficking seems to be restricted to the oligodendrocyte cell body. In this review, we summarize the evidence on the existence of different trafficking pathways in the oligodendrocyte, and discuss possible mechanisms separating the oligodendrocyte's membrane domains.     

On the biogenesis of myelin membranes: Sorting, trafficking and cell polarity

In the central nervous system, a multilayered membrane layer known as the myelin sheath enwraps axons, and is required for optimal saltatory signal conductance. The sheath develops from membrane processes that extend from the plasma membrane of oligodendrocytes and displays a unique lipid and protein composition. Myelin biogenesis is carefully regulated, and multiple transport pathways involving a variety of endosomal compartments are involved. Here we briefly summarize how the major myelin proteins proteolipid protein and myelin basic protein reach the sheath, and highlight potential mechanisms involved, including the role of myelin specific lipids and cell polarity related transport pathways.

Healing and the invention of metaphor: The effectiveness of symbols revisited

In this essay, I argue that a theory of meaning adequate to account for the effectiveness of symbolic healing and psychotherapy requires some variant of the three concepts of myth, metaphor and archetype. Myth stands for the overarching narrative structures of the self produced and lent authority by cultural tradition. Archetype stands not for preformed ideas or images, but for the bodily-given in meaning. Metaphor occupies an intermediate realm, linking narrative and bodily-given experience through imaginative constructions and enactments that allow movement in sensory-affective quality space. This pluralistic perspective itself constitutes a middle-ground between constructivist and realist approaches to meaning that can integrate causal and interpretive models of symbolic healing.I am manipulating, says the Alchemist. No, you are dreaming, says Novalis. I am dreaming, says Novalis. No, you are manipulating. The reason for such a profound duality is that fire is within us and outside us, invisible and dazzling, spirit and smoke.     

Risk, medicine and women: a case study on prenatal genetic counselling in Brazil

Genetic counselling is an important aspect of prenatal care in many developed countries. This tendency has also begun to emerge in Brazil, although few medical centres offer this service. Genetic counselling provides prenatal risk control through a process of individual decision-making based on medical information, in a context where diagnostic and therapeutic possibilities overlap. Detection of severe foetal anomalies can lead to a decision involving possible termination of pregnancy. This paper focuses on medical and legal consequences of the detection of severe foetal anomalies, mainly anencephaly and Down syndrome, and in light of the fact that abortion is illegal in Brazil. The discussion is based on the literature and empirical research at a high-complexity public hospital in Rio de Janeiro.     

Animals and the invention of the Phanerozoic Earth system

Animals do not just occupy the modern biosphere, they permeate its structure and define how it works. Their unique combination of organ-grade multicellularity, motility and heterotrophic habit makes them powerful geobiological agents, imposing myriad feedbacks on nutrient cycling, productivity and environment. Most significantly, animals have 'engineered' the biosphere over evolutionary time, forcing the diversification of, for example, phytoplankton, land plants, trophic structure, large body size, bioturbation, biomineralization and indeed the evolutionary process itself. This review surveys how animals contribute to the modern world and provides a basis for reconstructing ancient ecosystems. Earlier, less animal-influenced biospheres worked quite differently from the one currently occupied, with the Ediacaran-Cambrian radiation of organ-grade animals marking a fundamental shift in macroecological and macroevolutionary expression.     

Luminometer development in the last four decades: recollections of two entrepreneurs

This article, written by two entrepreneurs in luminescence, traces their involvement in the major part of the interconnected innovation and development of luminometers, adenosine triphosphate (ATP) bioluminescence and other technologies from the mid‐1970s to 2011 that ushered in much of the field of luminometry as we know it today. Key developments leading to current commercial applications of ATP bioluminescence, luminescence immunoassay, cellular luminescence, reporter gene and other applications are described from the first tube luminometers derived from early luminescence studies using liquid scintillation counting technology to measuring bioluminescence from crude ATP and firefly tail extracts.
