Protection of Investors and Credit Rating Agencies Regulation in Latin America  [PDF]
Márcio Ferro Catapani
Beijing Law Review (BLR) , 2018, DOI: 10.4236/blr.2018.94032
Abstract: The growth and expansion of economies of developing countries rely, in a great extension, on the access to financing sources for entrepreneur activities. Capital markets are one of the most efficient alternatives for local companies to have access to capitals, either local or foreign, and, therefore, for the boosting of the economic progress of such countries. In this sense, a legal framework of capital markets that fulfill the requirements of stability, certainty and security are essential in order to countries to compete for international capitals and investments. Indeed, such requirements are imperative to grow an environment of confidence of investors. Among other important issues in the capital markets regulation scope, there are two that have a vital importance to induce the confidence of investors and, consequently, to attract investment: the legal protection of investors and the regulation of the activities of credit rating agencies. It is vital that the legal system sets a framework for the protection of investors in the capital markets. The need of a stable, clear and secure framework does not imply an excessive intervention of the state in the ability of private economic agents to regulate their own interests. On the contrary, the state shall only provide for the minimum content of the financial services agreement and assure the compliance of the obligations taken under a contract. Furthermore, as the investment decisions made by economic agents rely mostly on the information they have on the financial instruments that are offered in the market, rules determining the full disclosure of information are essential. Concerning credit rating agencies, it is important to understand the role that such entities have undertaken in capital markets. Information about companies and financial instruments is the material economic agents use to make their investment decisions. But the cost to process and analyze the whole bunch of available data is too high for most agents, so they have to rely on the opinion of experts, such as credit rating agencies. In this context, regulation shall assure that the aforementioned agencies act in a fair and transparent way. Rules concerning conflict of interests, publicity of the criteria of rating analysis, and supervision on the activities of agencies are important to the growth of a sound capital market and an investment friendly environment. The article will focus on some of the production-centered jurisdictions—Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. They were chosen because they are the major

End of life care in Brazil: the long and winding road

Critical Care , 2011, DOI: 10.1186/cc9962
Abstract: In a recent issue of Critical Care, Fumis and Deheinzelin [1] evaluated the attitudes regarding end-of-life (EOL) decisions of physicians, nurses and family members in 13 Brazilian ICUs. Participants were asked whether mechanical ventilation should be withdrawn from two hypothetical terminally ill patients (one incompetent and another competent) and who should be involved in the decision-making process. The authors demonstrated that three-quarters of all groups of respondents agreed that withdrawal from mechanical ventilation should be considered for the competent patient. On the other hand, when faced with the clinical scenario of the incompetent patient, physicians were less likely to propose such a decision, in disagreement with nurses and family preferences. Additionally, most respondents shared the opinion that physicians, nurses, family members and patients themselves should necessarily be involved in the decision to withdraw life-sustaining therapies regardless of the scenario.The results of the above mentioned study have potential implications, as disagreements between the perceptions of nurses and physicians regarding EOL decisions are common [2], and many ICU patients lack the capacity to participate in discussions and make decisions about their diagnosis, proposed treatments, and prognosis. When a patient is unable to make decisions, family members are automatically turned to as surrogates to decide and consent for advanced therapeutic interventions and for EOL decisions. However, family members are frequently unaware of patients' wishes and preferences in the case of critical illness. Gaps in communication, disregarding families' and patients' preferences, and disagreements in expectancies at the EOL are well-known sources of conflicts with devastating consequences for healthcare workers, patients and family members, such as burnout, depression, anxiety and post-traumatic stress disorders [3-6]. In addition, conflicts at the EOL are perceived as much mor

Abstract: new occurrences for two heliconius kluk species are reported for sites in inland bahia, brazil. new inland sites are reported for heliconius sara (fabricius), a species normally found at coastal regions. to our knowledge, heliconius besckei ménétriés, a species restricted to cool mountain habitats, is reported for northeastern brazil for the first time.
Herbivore handling of a Plant?s trichome: the case of Heliconius charithonia (L.) (Lepidoptera: Nymphalidae) and Passiflora lobata (Killip) Hutch. (Passifloraceae)
Cardoso, Márcio Z.;
Neotropical Entomology , 2008, DOI: 10.1590/S1519-566X2008000300002
Abstract: trichomes reduce herbivore attack on plants by physically and/or chemically inhibiting movement or other activities. despite evidence that herbivores are negatively affected by trichomes there also reports of insect counter-adaptations that circumvent the plant?s defense. this paper reports on a study that investigated the likely mechanisms employed by larvae of the nymphalid butterfly, heliconius charithonia (l.), that allow it to feed on a host that is presumably protected by hooked trichomes (passiflora lobata (killip) hutch). evidence were gathered using data from direct observations of larval movement and behavior, faeces analysis, scanning electron microscopy of plant surface and experimental analysis of larval movement on plants with and without trichomes (manually removed). the latter involved a comparison with a non specialist congener, heliconius pachinus salvin. observations showed that h. charithonia larvae are capable of freeing themselves from entrapment on trichome tips by physical force. moreover, wandering larvae lay silk mats on the trichomes and remove their tips by biting. in fact, trichome tips were found in the faeces. experimental removal of trichomes aided in the movement of the non specialist but had no noticeable effect on the specialist larvae. these results support the suggestion that trichomes are capable of deterring a non specialist herbivore (h. pachinus). the precise mechanisms that allow the success of h. charithonia are not known, but i suggest that a blend of behavioral as well as physical resistance mechanisms is involved. future studies should ascertain whether larval integument provides physical resistance to trichomes.
Reflex?es sobre o contexto institucional Brasileiro contemporaneo e as transforma??es na educa??o profissional
Jacometti, Márcio;
Educar em Revista , 2008, DOI: 10.1590/S0104-40602008000200016
Abstract: the objective of this article is to consider research that verifies how the brazilian institutional context has affected the occurred transformations in professionalizing education, since 1964. one is about a theoretical essay that recommends the historical research, of descriptive character. the contextualization of the facts allows us to interpret and to compose the scene of the transformations of the professional education, in the period of analysis. the relation of influence between the institutional context and the occurred transformations in the brazilian professional education can be verified by means of qualitative analysis that uses relation mappings to be generated for documentary analysis. the results to be gotten will allow us to confirm or to refute the hypotheses that the institutional contexts and the spread values, for occasion of considered the two promulgation of ldbs: 1971 and 1996. they are not differentiated and they are characterized as neoliberal and the coercitive and normative contextual pressures have significantly affected the occurred transformations in the brazilian professional education. the inquiry of these hypotheses will propitiate an excellent study and will extend the understanding of the routes determined for the professional education and its consequences throughout time, making also possible, a future projection, facing the maintenance trend and homogenization of the legitimated values in the brazilian society by means of efficient mechanisms of domination.

Costa, Márcio da;
Educa??o em Revista , 2010, DOI: 10.1590/S0102-46982010000200011
Abstract: the article brings up results from a piece of research carried out in six municipal schools holding opposed reputations. we accomplished structured observa tions, interviews and questionnaires in three very different areas of rio de janeiro. the demand for the schools and the perception of the educational bureaucracy were the cri teria for their school's selection. the research seeks to understand how the school pres tige arises and is sustained, considering that this prestige is a relevant factor for the dis tribution of educational opportunities and is strongly tied to social hierarchies and strat ification. we highlight hierarchies and social inequalities within social contexts that are usually thought of as homogenous: the "ordinary" public schools. the pertinent litera ture was reviewed with special attention to school choice and segmentation among and within schools. some results were selected stressing the strength of the family condition ing to help comprehending the phenomenon under our focus.
Estudo experimental do uso de um antagonista do receptor da glicoproteína IIb/IIIa das placentas na preven??o de tromboses em microanastomoses vasculares
Oide, Márcio Issamu;
Acta Ortopédica Brasileira , 2000, DOI: 10.1590/S1413-78522000000200002
Abstract: the author has experimentally compared the efficacy of the platelet glycoprotein iib/iiia receptor antagonist (abciximab) in the prevention of platelet aggregation and thrombosis in microvascular surgery using rat models. twenty rats were used: ten rats were used as a control group and received saline; tem rats received abciximab 0.8 mg/kg administered in the femoral vein. after thirty minutes following administration, all rats underwent vascular thrombosis of the opposite femoral artery through an external trauma promoted by impactor, a device developed by the new york university to serve as a model of the spinal cord injury and the arterial damage. all rats were submitted to microvascular anastomoses using mononylon 10-0 and separated suture at the site of the external trauma. patency tests were performed on femoral arteries 10, 20 and 30 minutes after microanastomoses. all femoral arteries were removed for pathological studies to detect presence or absence of thrombus generation at the microanastomoses. after statistical analyses, the author concluded that the use of the platelet glycoprotein iib/iiia receptor antagonist (abciximab) avoided platelet aggregation and thrombosis in microvascular surgery.
Folclore e medicina popular na Amaz?nia
Henrique, Márcio Couto;
História, Ciências, Saúde-Manguinhos , 2009, DOI: 10.1590/S0104-59702009000400008
Abstract: this discussion of the relations between folklore and popular medicine in the amazon takes canuto azevedo's story "filhos do boto" (children of the porpoise) as an analytical reference point. replete with elements of cultural reality, folk tales can serve as historical testimonies expressing clashes between different traditions. folk records are fruit of what is often a quarrelsome dialogue between folklorists, social scientists, physicians, and pajés and their followers, and their analysis should take into account the conditions under which they were produced. based on the imaginary attached to the figure of the porpoise - a seductive creature with healing powers - the article explores how we might expand knowledge of popular medicine as practiced in the amazon, where the shamanistic rite known as pajelan?a cabocla has a strong presence.
Escravos no purgatório: o leprosário do Tucunduba (Pará, século XIX)
Henrique, Márcio Couto;
História, Ciências, Saúde-Manguinhos , 2012, DOI: 10.1590/S0104-59702012000500009
Abstract: the article analyzes the experience of the slaves interned at the tucunduba leprosarium in belém, state of pará during the nineteenth century. the slaves were freed once they showed the marks of their leprosy, and expectations were that they would submit to the segregation policy meant to keep them from contact with the rest of the population. the documentation produced by santa casa de misericórdia hospital in pará and by the province's political authorities reveals the strategies the slaves devised in response to this policy; they used their numerical predominance at the leprosarium to create a network of solidarity that allowed them to recreate their lives and stand in opposition to the type of nation that the era's hygienist theories envisioned.
