Youth and Social Security Coverage in Brazil  [PDF]
Paulo Tafner, Carolina Botelho
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.21014
Abstract: Brazil is still a young country, just starting the process of aging, but Brazils spending on social security is similar to those countries whose population aging has already occurred. Some studies explain the high cost of the Brazilian Social Security System due to the assumption that there is a positive relationship between social security and poverty alleviation. In fact, the effectiveness of this instrument as reducing poverty was high until 2002, but stopped growing and fell slightly thereafter. Brazilian law provides that wives and children or stepchildren under age 21, or under 25, since they are college students, are welfare beneficiaries. In other words they are protected by Brazilian Social Security System. However, data reveals that in Brazil, children and young people have a very low social security direct coverage, which increases with age and reaches high levels for individuals aged 60 or older. Children and young people are the groups most affected by poverty and extreme poverty in Brazil. In this sense, the assumption according to which Social Security helps combat family poverty is flawed. Considering these issues, this article aims to contribute to the debate on the need to rethink the Brazilian Social Security System and the need of construction of specific policies for children and young people in Brazil.
Governos de Coaliz?o e Mecanismos de Alarme de Incêndio no Controle Legislativo das Medidas Provisórias
Amorim Neto, Octavio;Tafner, Paulo;

Abstract: this article discusses the relationship between the executive and legislative branches in brazil with regard to the issuing of provisional measures (pms) by the former. the article contends that the legal ability of the brazilian chief of state to issue decrees with the force of law and taking force immediately (i.e., pms) does not imply that members of congress have abdicated from their legislative prerogatives in favor of the executive branch, as proposed by some authors analyzing the issue. after presenting the most important analyses of the dynamics in the executive-legislative relationship, the article aligns itself with the interpretation emphasizing the process of mutual delegation and control between the two powers, contending that the formation of a solid coalition government generates incentives for the executive to issue pms that meet the interests of the legislative majorities, and that congress is also capable of inferring whether such measures meet its interests, by way of an indirect supervisory mechanism known as the "fire alarm". the article proposes that it is possible to view pms as part of a complex and changing context of delegation within brazilian presidentialism, involving neither usurpation nor abdication.

Como os manuais de português para estrangeiros tratam a express o da futuridade?
Elisabeth Penzlien Tafner
Revista Brasileira de Linguística Aplicada , 2007,
Abstract: A língua portuguesa disp e de diferentes variedades lingüísticas para expressar a futuridade. Estas s o empregadas pelos falantes conforme o interlocutor, local e assunto, porém a quantidade e a descri o dessas formas nos manuais de ensino de português para estrangeiros precisam de maior detalhamento. O trabalho de Tafner (2004) trata de sete formas verbais para a express o da futuridade, das quais apenas duas foram encontradas nos manuais, o que sugere a necessidade de uma revis o destes, a fim de mostrar o funcionamento do sistema lingüístico do português. Na análise efetuada a partir de alguns manuais, escolhidos aleatoriamente, verificamos que a maioria faz referência apenas ao futuro sintético (-rei) ou à forma vou -R ou a ambas, mas sem apresentar para o aluno uma descri o detalhada a respeito de sua ocorrência, contextos que propiciam o emprego de uma ou outra forma verbal. Conseqüentemente, a falta dessas observa es pode confundir o aluno quando ele tiver contato com outras formas de futuridade n o incluídas nos manuais de ensino de PLE. The Portuguese language has different linguistic variants to express future. These variants are used by the speakers according to their interlocutors, the place and subject at hand. However, the quantity and the description of theses forms in Portuguese teaching manuals for foreigners need to be more detailed. Tafner's (2004) study describes seven verb forms to express future. From these seven forms, only two were found in the manuals. This finding suggests the necessity of revising such verb forms in order to show the functioning of the Portuguese linguistic system. In the analysis of some Portuguese teaching manuals randomly selected, it was verified that the majority of them presents only the simple future (-rei) or the perifrastic form with -ir or both, without providing the student a complete description about their occurrence or contexts that foster the use of one or another. Consequently, the absence of these observations can confound the student when he meets other future forms not included in Portuguese teaching manuals for foreigners.

Marlon Jackson Tafner,Everaldo da Silva
Revista Gest?o Universitária na América Latina : Revista GUAL , 2011, DOI: http://dx.doi.org/10.5007/1983-4535.2011v4n3p248
Abstract: Para muitos, ganhar representa a perda dos outros. Isso significa que duas ou mais partes competem numa base fixa em que o vencedor fica com a melhor parte. Esse tipo de rela es é caracterizado por ser rígido, baseado no pre o, e n o no valor. S o, desse modo, rela es adversas e n o promovem o desenvolvimento das partes. Este artigo explora as várias formas de abordagem do relacionamento entre organiza es e, inevitavelmente, entre pessoas, procurando adotar uma abordagem diferente da seguida pelos investigadores, acadêmicos e praticantes quando se debru am sobre as rela es win-win entre organiza es. A considera o de aspectos resultantes das ciências humanas, combinada com o que de melhor as tradicionais abordagens têm para oferecer, pode revelar-se muito importante e renovadora no estabelecimento e na manuten o de rela es win-win.

Abstract: aim: to evaluate the influence of socioeconomic, clinical and demographic variables on caries experience in 5-year-old preschool children from piracicaba. methods: the sample consisted of 728 children attending 22 public (n=428) and 18 private (n=300) preschools. dental caries were measured using the dmft/dmfs indexes and by detecting initial caries lesion (il). gingivitis, crowding, spacing, fluorosis, and mouth breathing were also recorded. socioeconomic variables (monthly family income, number of people living in the household, parents' schooling, home ownership, and car ownership) were collected by means of a parental semi structured questionnaire. results: the mean (standard deviation) values for dmft and dmfs indexes were 1.30 (2.47) and 3.08 (7.55) respectively; and 62.2% of the children were caries-free. the mean (standard deviation) values for dmft+li and dmfs+li were 1.72 (3.36) and 3.45 (7.94), respectively and 59.7% were caries-free. by means of multiple logistic regression analyses, children with fluorosis (or=0.40) or family income > 4 minimum wages (or=0.49) were less likely to experience caries. those with gingivitis (or=1.87) were more prone to have the disease. considering the diagnostic threshold including il, the multiple logistic regression analyses showed that children with fluorosis (or=0.39) or family income > 4 minimum wages (or=0.52) were less likely to have caries. those with gingivitis (or=1.80), crowding (or=2.63 e or=1.01) or mouth breathing (or=1.37) were more likely to have the disease. conclusion: the preschool children who presented gingivitis, crowding, mouth breathing or monthly family income < 4 minimum wages were more likely to experience caries. in this way, planning preventive and operative actions targeted at these children would be essential for caries control.
Influence of Coolant in Machinability of Titanium Alloy (Ti-6Al-4V)  [PDF]
Muthukrishnan Namb, Davim Paulo
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2011, DOI: 10.4236/jsemat.2011.11002
Abstract: Application of titanium alloy has increased many fields since the past 50 years. The major drawback encountered during machining was difficult to cut and the formation of BUE (Built up Edge). This paper presents the tool wear study of TTI 15 ceramic insert (80% Aluminum oxide and 20 % Titanium carbide) on machining Ti-6Al-4V at moderate speed with and without the application of water soluble servo cut S coolant. Titanium alloy is highly refractory metal and machining titanium is challenging to the manufacturers. Experiments were carried out on medium duty lathe. Application of coolant tends to reduce toolwear and minimize adhesion of the work material on the cutting tool during machining and also improves the surface finish. Result provides some useful information.
Warming Power of CO2 and H2O: Correlations with Temperature Changes  [PDF]
Paulo Cesar Soares
International Journal of Geosciences (IJG) , 2010, DOI: 10.4236/ijg.2010.13014
Abstract: The dramatic and threatening environmental changes announced for the next decades are the result of models whose main drive factor of climatic changes is the increasing carbon dioxide in the atmosphere. Although taken as a premise, the hypothesis does not have verifiable consistence. The comparison of temperature changes and CO2 changes in the atmosphere is made for a large diversity of conditions, with the same data used to model climate changes. Correlation of historical series of data is the main approach. CO2 changes are closely related to temperature. Warmer seasons or triennial phases are followed by an atmosphere that is rich in CO2, reflecting the gas solving or exsolving from water, and not photosynthesis activity. Interannual correlations between the variables are good. A weak dominance of temperature changes precedence, relative to CO2 changes, indicate that the main effect is the CO2 increase in the atmosphere due to temperature rising. Decreasing temperature is not followed by CO2 decrease, which indicates a different route for the CO2 capture by the oceans, not by gas re-absorption. Monthly changes have no correspondence as would be expected if the warming was an important absorption-radiation effect of the CO2 increase. The anthropogenic wasting of fossil fuel CO2 to the atmosphere shows no relation with the temperature changes even in an annual basis. The absence of immediate relation between CO2 and temperature is evidence that rising its mix ratio in the atmosphere will not imply more absorption and time residence of energy over the Earth surface. This is explained because band absorption is nearly all done with historic CO2 values. Unlike CO2, water vapor in the atmosphere is rising in tune with temperature changes, even in a monthly scale. The rising energy absorption of vapor is reducing the outcoming long wave radiation window and amplifying warming regionally and in a different way around the globe.
Leverage and the Maturity Structure of Debt in Emerging Markets  [PDF]
Cesario Mateus, Paulo Terra
Journal of Mathematical Finance (JMF) , 2013, DOI: 10.4236/jmf.2013.33A005
Abstract:

The aim of this paper is to analyse for a multi-country large emerging market sample the choice between debt and equity simultaneously with the decision between short- and long-term debts. In order to investigate the joint decision among leverage and maturity, we examine an unique sample of 986 firms and 13,490 firm-year observations from Latin America and 686 firms and 7919 firm-year observations from Eastern Europe for the period 1990-2003. We employ dynamic panel data analysis using Generalized Method of moments. The empirical results support three main findings. First, the cross-effects between leverage and maturity behave exactly the opposite between Latin America and Eastern Europe sub-samples. Capital structure and debt maturity are policy complements in Latin America and substitutes in Eastern Europe. Second, there is a significant dynamic effects component in the determination of leverage and maturity. Finally, adjustment to the target, maturity is by no means costless and instantaneous with firm’s facing moderate adjustment costs.
