ERICA: intake of macro and micronutrients of Brazilian adolescents

ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). Food intake was estimated using 24-hour dietary recall (24-HDR). A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL). The Estimated Average Requirement (EAR) method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years) to 2,582 kcal (boy aged from14 to 17 years). Saturated fat and free sugar intake were above the maximum limit recommended (< 10.0%). Vitamins A and E, and calcium were the micronutrients with the highest prevalence of inadequate intake (> 50.0%). Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.

Convergence and divergence in global economy and social development : global perspectives on the contents of economic and soical development policy and its effects on rich and poor countries

The study of convergence and divergence in global economy and social development utilises comparative indicators to investigate the contents of economic and social development policy and their effects on the global samples that represent the rich industrial, semi-industrial and the poor developing nations. The study searchesfor answers to questions such as "what are the objectives of economic growth policies in globalisation under the imperatives of convergence and divergence, and how do these affect human well-being in consideration to the objectives of social policy in various nations?" The empirical verification of data utilises the concepts of the `logic of industrialism´ for comparative analysis that focuses mainly on identifying the levels of well-being in world nations after the Second World War. The perspectives of convergence and divergence in global economy and social development critically examine the stages of early development processes in global economy, distinguish the differences between economy and social development, illustrate the contents of economic and social development policies, their effects on rich and poor countries, and the nature of convergence and divergence in propelling economic growth and unequal social development in world nations. The measurement of convergence and divergence in global economy and social development utilised both economic and social data that were combined into an index that measures the precise levels of the effects of economic and social development policies on human well-being in the rich and poor nations. The task of finding policy solutions to resolve the controversies are reviewed through empirical investigations and the analyses of trends indicated within economic and social indicators and data. These revealed how the adoption of social policy measures in translating the gains from economic growth, towards promoting education, public health, and equity, generate social progress and longer life expectancy, higher economic growth, and sustain more stable macro economy for the nations. Social policy is concerned with the translation of benefits from objectives of global economic growth policies, to objectives of social development policy in nation states. Social policy, therefore, represents an open door whereby benefits of economic growth policies are linked with the broader objectives of social development policy, thereby enhancing the possibility of extending benefits from economic growth to all human being in every nation.

Do Código Florestal para o Código da Biodiversidade

Em face do gigantismo do território e da situação real em que se encontram os seus macro biomas - Amazônia Brasileira, Brasil Tropical Atlântico, Cerrados do Brasil Central, Planalto das Araucárias, e Pradarias Mistas do Brasil Subtropical - e de seus numerosos mini-biomas, faixas de transição e relictos de ecossistemas, qualquer tentativa de mudança no "Código Florestal" tem que ser conduzido por pessoas competentes e bioeticamente sensíveis. Por muitas razões, se houvesse um movimento para aprimorar o atual Código Florestal, teria que envolver o sentido mais amplo de um Código de Biodiversidades, levando em conta o complexo mosaico vegetacional de nosso território. Enquanto o mundo inteiro trabalha para a diminuição radical de emissão de CO2, o projeto de reforma proposto na Câmara Federal de revisão do Código Florestal defende um processo que significará uma onda de desmatamento e emissões incontroláveis de gás carbônico, fato observado por muitos críticos em diversos trabalhos e entrevistas. A utopia de um desenvolvimento com o máximo de florestas em pé não pode ser eliminada por princípio em função de mudanças radicais do Código Florestal, sendo necessário pensar no território total de nosso país, sob um ampliado e correto Código de Biodiversidade. Ou seja, um pensamento que envolva: as nossas grandes florestas (Amazônia e Matas Tropicais Atlânticas); o domínio das caatingas e agrestes sertanejos; planaltos centrais com cerrados, cerradões e campestres; os planaltos de araucárias sul-brasileiros; as pradarias mistas do Rio Grande do Sul; e os redutos e mini-biomas da costa brasileira e do Pantanal mato-grossense, e faixas de transição e contrato (core-áreas) de todos os domínios morfoclimáticos e fitogeográficos brasileiros).

Economic analysis for sizing of sugarcane (Saccharum spp.) mechanized harvesting

Sugarcane has a significant role on Brazilian agribusiness economy. The harvesting cane is considered as one of the most important operations of the process for it has to attend the raw material demanded by the sugar mill in quality and a competitive cost. The objective of this work it is it of analyzing, of systemic way, the variables influence on economical and operational performance in sugarcane mechanized harvesting process for sizing of machines. For this purpose a model called "ColheCana", was developed in a spreadsheet and in a programming language. The results showed that the field efficiency and harvester´s initial value are variables of great impact in the cost and that there is a maximum area that one equipment can attend and for this area the cost is minimum.

Macroanálise, regulação e o método uma alternativa ao holismo e ao individualismo metodológicos para uma macroeconomia histórica e institucionalista

Macro-analysis, regulation and the method: an alternative to the methodological holism and individualism to a historical and institutionalist macro-economy. The paper examines the epistemological conditions that make the "regulationist" macro-analysis a possible alternative to the traditional equilibrium approaches. It shows how these analyses allow to overcome the structure-agent dilemma as from the concept of contextual rationality and of a hol-individualist methodology that, combined with the notion of strong historicity, find wide theoretical basis in Bourdieu's sociology, in Braudel's works on economical history and in Lukács's ontology on the social being. The paper also explains its historical origins and concludes with a synthesis of the method and the necessary steps to accomplish this type of macroeconomics approach.

La crise du syndicalisme comme crise de la représentation des travailleurs : une étude de cas de l'évolution des identités collectives dans l'économie solidaire au Brésil.

Cette thèse part du postulat que la crise du syndicalisme résulte d’une remise en cause des identités collectives ayant légitimé jusque dans les années 70 leur représentation des travailleurs. En témoignent les mobilisations, qui se déroulent souvent en dehors des syndicats et de façon conflictuelle avec eux, de travailleuses et travailleurs longtemps minorés par les arrangements institutionnels prévalant avec la société salariale. Différents travaux dans le renouveau syndical relèvent de leur côté que les syndicats peinent à prendre en compte les besoins et aspirations de ces travailleurs car leur identité collective les entraîne à rester dans les sentiers des orientations et représentations institutionnalisées. Cependant, les auteurs se focalisent sur la façon dont le syndicalisme, et en particulier les leaders, peuvent reconstruire une représentation des travailleurs, et non sur la façon dont les identités collectives se transforment. Les études sur le syndicalisme héritent d’un débat sur les mouvements sociaux qui a abouti à scinder les approches théoriques entre celles conceptualisant les identités collectives, mais dans le cadre de théorisations contestables de l’évolution des sociétés, et celles qui sous-théorisent les identités collectives et considèrent que les mouvements sociaux émergent des processus politique et de la mobilisation des ressources. Les travaux sur le renouveau syndical reprennent généralement cette seconde approche et assimilent les mouvements de travailleurs à des organisations en considérant, implicitement, les buts de l’action collective comme donné. Or, un mouvement social est un concept ; il n’est pas réductible à une organisation, au risque sinon de perdre sa valeur heuristique, qui est de chercher à saisir les identités collectives en conflit et les stratégies associées. À partir de l’étude du cas du mouvement de travailleurs dans l’économie solidaire brésilienne, cette thèse questionne donc le « pourquoi de nouvelles identités collectives de travailleurs émergent » et le « comment ou le pourquoi des identités syndicales se transforment ou se reproduisent », lorsqu’elles sont confrontées à l’émergence de nouvelles façons de définir les dominations à combattre et les orientations. Les identités collectives sont opérationnalisées comme des matrices cognitives et normatives, ce qui permet de rendre compte de leur caractère évolutif en fonction des modalités d’interaction. L’étude de cas met en évidence que les mobilisations autonomes des travailleurs minorés sont porteuses de nouvelles définitions des problèmes et de pratiques sociales transformatrices, qui entrent en conflit avec les significations et les pratiques syndicales institutionnalisées. Elle montre que c’est à la suite d’interactions délibératives entre ces travailleurs et les syndicalistes que les identités syndicales se transforment. Cependant, la reconstitution des trajectoires de deux syndicats (de la principale centrale brésilienne) indique que le fait d’entrer dans de telles interactions ne dépend pas d’une décision rationnelle, mais de la perception (de la part des syndicats) des capacités des travailleurs à transformer le rapport au travail et au monde lorsqu’ils agissent collectivement. Un dernier résultat, corollaire, tient dans la falsification de l’hypothèse – défendue par une partie de la littérature sur le renouveau syndical – selon laquelle les syndicats, et en particulier les leaders, peuvent conduire une transformation de la représentation collective en procédant eux-mêmes à une agrégation des multiples identités collectives. Cette hypothèse, qui revient à considérer le but de l’action collective comme donné, est contredite par les données : elles montrent que, dans un tel cas, s’il y a bien des innovations institutionnelles conduites par le syndicat, ces innovations favorisent l’adaptation du syndicalisme aux mutations du capitalisme et non la transformation des rapports sociaux de domination, parce que prédominent alors les liens sociaux avec les groupes dominants, c’est-à-dire les interprétations cognitives dominantes des problèmes.

Low-frequency volatility of real estate securities in relation to macroeconomic risk

Real estate securities have a number of distinct characteristics that differentiate them from stocks generally. Key amongst them is that under-pinning the firms are both real as well as investment assets. The connections between the underlying macro-economy and listed real estate firms is therefore clearly demonstrated and of heightened importance. To consider the linkages with the underlying macro-economic fundamentals we extract the ‘low-frequency’ volatility component from aggregate volatility shocks in 11 international markets over the 1990-2014 period. This is achieved using Engle and Rangel’s (2008) Spline-Generalized Autoregressive Conditional Heteroskedasticity (Spline-GARCH) model. The estimated low-frequency volatility is then examined together with low-frequency macro data in a fixed-effect pooled regression framework. The analysis reveals that the low-frequency volatility of real estate securities has strong and positive association with most of the macroeconomic risk proxies examined. These include interest rates, inflation, GDP and foreign exchange rates.

Educação para a igualdade na perspectiva de gênero

Este trabalho tem como principal objetivo refletir sobre as questões de gênero e diversidade nas políticas públicas de educação no Brasil. O propósito foi analisar o esforço investido em mudanças no processo de formação básica, que buscam tornar a escola um lugar mais igualitário, preparado para cumprir seu papel na formação de sujeitos para o exercício da cidadania. Também foi finalidade da pesquisa captar a percepção dos educadores em face desse esforço. Como estudo de caso, foi tomado o curso piloto do projeto Gênero e Diversidade na Escola (GDE), que propõe, através de formação complementar, uma discussão com educadores sobre assuntos da diversidade, gênero, sexualidade e relações étnico-raciais. O curso GDE, realizado no ano de 2006, ofertou 1200 vagas para professores do ensino fundamental de seis municípios das cinco regiões brasileiras: Dourados/MS, Niterói e Nova Iguaçu/RJ, Maringá/PR, Porto Velho/RO e Salvador/BA. Para viabilizar a pesquisa foram analisados 60 memoriais, desenvolvidos como parte da avaliação final dos professores que participaram do projeto.

Razão de prevalências: Alcoolismo nas diferentes regiões geográficas do Brasil segundo o sexo

The present study applies a method of prevalence analysis to data obtained in two nationwide household surveys on alcohol use during life and dependence, for each of the sexes. The ratios of prevalences (R), for the lifetime alcohol use and dependence rates, between the two genders in the various Brazilian macro-regions, were calculated together with their respective 95% confidence intervals. It was found that lifetime use, both in 2001 and in 2005, was significantly greater in Brazilian males in all geographical regions. In 2001, the population of the North (male and female) had a higher rate of alcohol consumption than that in the Brazilian population as a whole and that in the Southeast. Dependence on the consumption of alcoholic drinks in 2001 and in 2005 was greater in the male sex, but similar among the various regions studied. It can be concluded that this method of analyzing the data on alcoholism could be of great use in assessing its magnitude and importance in terms of public health.

An assessment of the economic impact of climate change on the tourism sector in Jamaica

Climate change is a continuous process that began centuries ago. Today the pace of change has increased with greater rapidity because of global warming induced by anthropogenically generated greenhouse gases (GHG). Failure to effectively deal with the adverse outcomes can easily disrupt plans for sustainable economic development. Because of the failure of export agriculture over the last several decades, to provide the economic stimuli needed to promote economic growth and development, Jamaica, like many other island states in the Caribbean subregion, has come to rely on tourism as an instrument of transformation of the macro-economy. It is believed this shift in economic imperative would eventually provide the economic impetus needed to generate much needed growth and development. This assessment has shown that tourism is not only a leading earner of foreign exchange in Jamaica and a major creator of both direct and indirect jobs but, also, one of the principal contributors to the country‟s Gross Domestic Product (GDP). The rapid expansion of the industry which occurred over the last several decades coupled with disregard for sound environmental practices has led to the destruction of coral reefs and the silting of wetlands. Because most of the industry is located along the coastal region it is extremely vulnerable to the adverse effects of climate change. Failure to address the predictable environmental challenges of climate change, with some degree of immediacy, will not only undermine, but quickly and seriously impair the capacity of industry to stimulate and contribute to the process of economic development. To this end, it important that further development of industry be characterised by sound economic and social planning and proper environmental practices.
