The Globalization-Deglobalization Policy Conundrum  [PDF]
Neil Dias Karunaratne
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.34048
Abstract: The dynamic process of economic globalization and deglobalization has been occurring in “waves” over the past 250 years. Diffusion models reveal how globalization policies occupy the policy-centre stage when the global economy is booming and is cast on the back-burner when the global economy nose-dives into a slump. According to the diffusion models, when the global economy is booming the nodes that establish crucial linkages in the economy exceed the social optimum generating negative externalities thereby eroding social welfare in such a context policy intervention is justified to reduce the linkages that facilitate the spread of negative shocks or contagion that reduce the capacity for risk- sharing. The globalization-deglobalization policy conundrum also resurfaces in relation to trade flows, cross-border capital mobility, current account sustainability and technology diffusion. The latter has exacerbate the “digital divide” that has accompanied the revolutionary changes in information and communication technology (ICT) revolution by overcoming the “tyranny of distance”. The recurrent global financial crises and speculative attacks on the currency peg have ignited the debate for reshaping the international financial architecture in order to reduce the vulnerability of the domestic economy to the disruptive effects of the global financial crises.
Nutritional Quality and Health Benefits of Vegetables: A Review  [PDF]

Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.310179
Abstract: Vegetables are considered essential for well-balanced diets since they supply vitamins, minerals, dietary fiber, and phytochemicals. Each vegetable group contains an unique combination and amount of these phytonutriceuticals, which distinguishes them from other groups and vegetables whithin their own group. In the daily diet vegetables have been strongly associated with improvement of gastrointestinal health, good vision, and reduced risk of heart disease, stroke, chronic diseases such as diabetes, and some forms of cancer. Some phytochemicals of vegetables are strong antioxidants and are thought to reduce the risk of chronic disease by protecting against free radical damage, by modifying metabolic activation and detoxification of carcinogens, or even by influencing processes that alter the course of tumor cells. All the vegetables may offer protection to humans against chronic diseases. Nutrition is both a quantity and a quality issue, and vegetables in all their many forms ensure an adequate intake of most vitamins and nutrients, dietary fibers, and phytochemicals which can bring a much-needed measure of balance back to diets contributing to solve many of these nutrition problems. The promotion of healthy vegetable products has coincided with a surging consumer interested in the healthy functionality of food. Because each vegetable contains a unique combination of phytonutriceuticals, a great diversity of vegetables should be eaten to ensure that individual’s diet includes a combination of phytonutriceuticals and to get all the health benefits. This article make a review and discusses the nutritional quality and health benefits of the major groups of vegetables. More interdisciplinary work is required that involves nutritional and food scientists as well as others from biomedical fields to ascertain the thrue function of specific phytonutriceuticals.
Anaphylatoxins: From Supposed Toxin Anaphylactics to Effective Mediators of the Early Events of Inflammation  [PDF]
Wilmar Dias da Silva
Open Journal of Veterinary Medicine (OJVM) , 2012, DOI: 10.4236/ojvm.2012.24043
Abstract: This review updates original data describing the experiments showing the complement origin of anaphylatoxins unexplainable submerged under the surface of the articles related to the subject. Next, recalls subsequent data describing the anaphylatoxins peptide nature and sequences, the cell receptors with which they interact and activate and the outcome of the cell responses. The review continues by highlighting the anaphylatoxin biological properties focusing on the unequivocal participation of these mediators in inflammation. The review concludes bringing data reinforcing the promising use of these peptides as molecular primers to create specific and efficient pharmacological antagonists.
Application of Laplace Transform for a Gas-Liquid-Solid Trickle Bed Reactor by Using the Tracer Technique  [PDF]
Jornandes Dias Silva
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.41A027

Experimental evaluation and dynamic modelling were presented for a liquid flow (H2O + NaOH tracer) on solid particles in a trickle bed reactor. One-dimensional dynamic mathematical model has been described to study the gas-liquid-solid process in which the liquid phase with the NaOH tracer is treated as a continuum. The physical model has been analyzed, including the formulation of initial and boundary conditions and the description of the solution methodology. An experimental setup to measure the concentrations of the NaOH tracer has been performed. The concentration measurements of this NaOH tracer have been performed in a fixed be reactor on trickling flow of the liquid phase for a range of operating conditions. The axial dispersion (Dax) of the liquid phase, liquid-solid mass transfer (kLS) coefficient and partial wetting efficiency (fe) were chosen as the hydrodynamic parameters of the proposed mathematical model. Such parameters have been optimized with experimental measurents of the NaOH tracer at the exit of the trickle-bed reactor. The optimized parameters (Dax, kLS, and fe) were calculated simultaneously by using the theoretical model with minimization of the objective function. Results of the proposed mathematical model have been presented and compared as of the two experimental cases. These hydrodynamic parameters were fitted by means of the empirical correlations.

Institui??es e desenvolvimento territorial: um estudo a partir do caso do arranjo produtivo de petróleo e gás natural localizado em Macaé-Brasil
EURE (Santiago) , 2013, DOI: 10.4067/S0250-71612013000100006
Abstract: in recent years the institutional approach has been gaining ground in urban and regional studies, defending that the norms, rules and cultural conventions should be taken into account in research andpolicies on territorial development. in this sense, the objective of this paper is to empirically examine some implications generated by the institutions in the economy of the productive arrangement of oil and natural gas in macaé, brazil. during the research it was found that the institutions operate at different scales, which in the study area can be segmented into two: external norms, which are imposed to the local level by agents with great power of usage of the space (the state and large companies) and institutions of local origin, formed from the reactions of local agents to external pressures. the main articulation was held by rede petro-b c, and its analysis is very suggestive to the understanding of the local institutional environment.
Paradiplomacia y turismo en las redes de ciudades del Mercosur
Estudios y perspectivas en turismo , 2011,
Abstract: with the intensification of globalization cities are becoming new international actors performing numerous activities that constitute a municipal diplomacy. this action undertaken by cities seeking to serve the interests of their community at a global level, regardless of the federal government has been named paradiplomacy. tourism is an activity that surpasses borders and is expanding in the mercosur, constituting an important element of cooperation between cities in different countries that seek increased integration in order to share flows of visitors who would benefit from several locations at the same period. this paradiplomatic activity in the mercosur is being carried out mainly through networks of cities.
Marketing ecológico y turismo
Estudios y perspectivas en turismo , 2008,
Abstract: the article intends to show the relevance green marketing has for tourism, in particular to nature-based tourism. at the same time, it points out the risks of the excessive use of strong ecological characters, such as ecotourism and the amazon amongst others, when associated to a low quality environmental product. it concludes assessing that with the growing importance of natural environmental in the tourism field, the environmental marketing should be used considering the parameters of social responsibility and ethics.
Educational system, income inequality and growth: the median voter's decision
Dias, Joilson;
Estudos Econ?micos (S?o Paulo) , 2005, DOI: 10.1590/S0101-41612005000100003
Abstract: i analyze a long run educational policy as a mechanism to close the income gap among low, median and high-income families. if the choice is made endogenous by the use of the median voter theorem, the results are as follow: i) public education system guarantees income convergence, however the income growth rate of the median voter is smaller; ii) the combination public and private (hybrid) educational system allows faster income growth rate, but income inequality is almost the natural outcome. the ending result is that the combination public and private system will prevail, since the income growth rate of the median voter is higher in this system. this might explain the persistence and differences of income inequality among the economies.
A representa??o da realeza no Brasil: uma análise dos retratos de D. Jo?o VI e D. Pedro I, de Jean-Baptiste Debret
Dias, Elaine;
Anais do Museu Paulista: História e Cultura Material , 2006, DOI: 10.1590/S0101-47142006000100008
Abstract: jean-baptiste debret, history painter and member of the french artistic mission of 1816, in his iconographic album picturesque and historical travel to brazil, has made illustrations from the observation of brazilian uses. part of his work was dedicated to the life of the court in brazil. the author seeks to in this article to analyze the conception of both the portrait of d. jo?o vi and the portrait of d. pedro i, official images of the royalty in brazil produced by the french artist. there is, in debret, a clear counterpoint between the portraits of the father d. jo?o and his son pedro, offering interpretative keys for the political moments in question. the author seeks to analyze and contrast the images, in the sense of their physical description - the differential presence of attributes and their political representation -, bringing to the surface the iconographic changes between the portraits, highlighting the importance of the european and american models in the compositions.
Correspondências entre Joachim Le Breton e a corte portuguesa na Europa: o nascimento da Miss?o Artística de 1816

Anais do Museu Paulista: História e Cultura Material , 2006, DOI: 10.1590/S0101-47142006000200009
Abstract: a series of documents kept at the national archive of tombo tower in lisbon offers us important tools to understand the origin of the 1 81 6 artistic mission. although some brazilian historians have already explored this field extensively - including afonso d'escragnolle taunay, mário barata and mário pedrosa in their invaluable publications, not to mention jean-baptiste debret in his writings - it is important to shed new light on this subject so that we may understand how the project of art and industrial education was conceived in europe byjoachim le breton. how did the mission's project come about? this paper proposes to review certain letters kept at the tombo tower and exchanged between portuguese diplomats and le breton in 1815, while the latter was still in paris, for the ultimate purpose of retracing the first steps of this story.
