El objetivo versus los instrumentos de la política pública: el caso de una reforma verde para la igualdad en México

Uno de los principales objetivos de México —y más ampliamente de América Latina— es abatir la pobreza y promover una mejor distribución del ingreso, riqueza y oportunidades. Si bien esto representa hoy día uno de los escasos consensos entre los distintos actores de la sociedad, la selección del (los) instrumento(s) para lograrlo está sujeto a un acalorado debate. A tal grado llega este último disenso que se ha llegado a confundir el instrumento tomándolo como el fin último. El propósito de esta nota es mostrar que la consecución del objetivo no debe perderse de vista y que la elección del instrumento para conseguirlo debería ponderarse en menor medida, de acuerdo a las circunstancias —políticas, económicas y sociales— específicas a cada país. En particular, aquí se argumenta que la introducción de un sistema de seguridad social universal es uno de los instrumentos fundamentales para reducir la pobreza y la brecha de desigualdad en el ingreso y oportunidades. Asimismo, se sostiene que una reforma verde puede generar gran parte de los ingresos necesarios para financiar dicho sistema. Antes de ello conviene iniciar describiendo brevemente la evolución de los indicadores clave del desarrollo económico, a saber, el crecimiento económico, el nivel de pobreza y el grado de desigualdad en la distribución del ingreso. A partir de aquí se sugiere una reforma alternativa para el caso de México.

Sustentabilidade e Inovação: um estudo sobre o plástico verde

O presente trabalho tem por objetivo verificar a perspectiva de possível substituição do plástico oriundo dos combustíveis fósseis não renováveis e esgotáveis pelo Plástico Verde, fabricado a partir do etanol de cana-de-açúcar, recurso renovável. O estudo consiste em uma pesquisa exploratória com abordagem qualitativa, realizada mediante análise de artigos técnicos, informações disponíveis no site da empresa Braskem e entrevistas com atores empresariais envolvidos com o tema. Como um dos resultados da análise, a substituição tende a se tornar realidade, mas a característica de o Plástico Verde não ser biodegradável foi apontado pelos respondentes como um desafio a ser resolvido. A maioria dos respondentes afirma que, não somente o Plástico Verde, mas todos os plásticos poderiam ter o aspecto da reciclagem melhor explorado, o que implica investimento em educação e em políticas públicas. As empresas percebem a utilização do Plástico Verde como um diferencial mercadológico e uma forma de colaboração com o meio ambiente, haja vista ele ser fabricado com 100% de fontes renováveis. Os resultados da pesquisa indicam que a melhoria da eficiência das plantações e de políticas de reciclagem tornam-se fundamentais para o sucesso deste processo, já que há demanda por diversos setores da economia, que começam a utilizá-lo em ampla escala. Segundo a maioria dos respondentes, o Plástico Verde originado da cana-de-açúcar alcançou relevante capacidade inovativa para mitigar a extração de petróleo.

A história do Senhor Bom Jesus da Cana Verde: conflitos e celebrações em torno de uma imagem religiosa (Siqueira Campos PR, 1933)

Essa dissertação abordou os conflitos que ocorreram no espaço geográfico denominado Norte Pioneiro . A imagem do Bom Jesus, de propriedade da família Pinto, foi expropriada pelo vigário da paróquia do Distrito de Salto do Itararé, padre Alfredo Simon, que reuniu cerca de vinte homens aramados para capturar esse santo. Nesse conflito religioso que ocorreu no dia 26/4/1933 duas pessoas foram mortas: o comerciante do Arraial dos Pintos, João Moreira, e o herdeiro do Bom Jesus, José Pinto de Oliveira. Esse último veio a falecer meses depois do conflito. Ao redor dessa imagem foi sendo criada uma história oficial e vigiada pelos donos do poder simbólico, mantenedora da ordem e da tradição. No entanto, a história do Bom Jesus foi compreendida numa concepção mais ampla, pois na esfera religiosa ocorria um fenômeno denominado de romanização. A Igreja Católica seguia o Código de Direito Canônico de 1917, não reconhecendo o Código de Direito Civil do Estado Nacional Brasileiro. Na esfera política, o governo paranaense colocou em prática o sistema de terras devolutas. No setor dos transportes, a estrada de ferro RVPRSC (Rede Viária Paraná Santa Catarina) já se encontrava na região desde 1919. E nesse ínterim, as novas relações sócio-culturais e econômicas foram introduzidas no campo, isto é, o capitalismo agrário.(AU)

Charles Perry and Nathaniel Reed in Mesa Verde Cave

Charles Perry and Nathaniel Reed in Mesa Verde cave, Arizona. Charles Edward Perry (Chuck), 1937-1999, was the founding president of Florida International University in Miami, Florida. He grew up in Logan County, West Virginia and graduated from Bowling Green State University. He married Betty Laird in 1961. In 1969, at the age of 32, Perry was the youngest president of any university in the nation. The name of the university reflects Perry’s desire for a title that would not limit the scope of the institution and would support his vision of having close ties to Latin America. Perry and a founding corps opened FIU to 5,667 students in 1972 with only one large building housing six different schools. Perry left the office of President of FIU in 1976 when the student body had grown to 10,000 students and the university had six buildings, offered 134 different degrees and was fully accredited. Charles Perry died on August 30, 1999 at his home in Rockwall, Texas. He is buried on the FIU campus in front of the Graham Center entrance. Reed, Nathaniel P. (Nathaniel Pryor), 1933- serves on the Board of the National Geographic Society, the Everglades Foundation where he is Vice Chairman, and the Hope Rural School for migrant children. He received a B.A. from Trinity College in Connecticut. He was an officer in the U.S. Air Force and was Assistant Secretary of the Interior for the U.S. Fish and Wildlife Service as well as the U.S. Parks Service. He has also served on the boards of the National Audubon Society, the Nature Conservancy, the National Parks and Conservation Association, and the American Rivers. He is a board member emeriti of the Natural Resources Defense Council and 1000 Friends of Florida. He served on various environmental organization and committees under seven different governors in the state of Florida including as Chairman of the Commission on Florida’s Environmental Future. In 1972 he received the Cornelius Amory Pugsley National Medal Award.

A 34-month sediment trap experiment at the Cape Verde Ocean Observatory (CVOO, December 2009 - October 2012)

Anticyclonic mesoscale eddies (ACME) have been proposed as a mechanism by which new nutrients are episodically delivered into the euphotic zone, thereby enhancing new production as well as shifting phytoplankton community structure. In this paper, we report on a 34-month sediment trap experiment at the Cape Verde Ocean Observatory (CVOO; ca. 18°N, 24°E; December 2009-October 2012), occasionally influenced by ACME passages. The typically oligotrophic, weakly seasonal particle flux pattern at the CVOO is strongly modified by the appearance of a highly productive and low oxygen ACME. Out of four recorded diatom flux maxima at CVOO, three were associated with the passage of ACMEs. The recorded diatom maxima events support the view that local ACME dynamics promotes upward nutrient supply into the euphotic zone leading to a rapid response of diatoms. This response is clearly reflected by the flux seasonality: between 40% and 60% of the total annual diatom flux at the CVOO site was intercepted in a relatively short time interval (<60 days). A highly diverse diatom community characterized the diatom fluxes throughout. Along with the ACME passages, small species of the genus Nitzschia, and Thalassionema nitzschioides var. parva dominated and delivered a major portion of the opal and organic carbon into deeper waters at site CVOO. Several pelagic, warm-water background species became dominant during intervals with low nutrient availability in the euphotic zone. Results of our interannual time-series suggest that ACMEs impact on total diatom production and the species-specific composition of the assemblage north of the Cave Verde Islands, and can strengthen the biological pump in open-ocean, oligotrophic subtropical regions of the world ocean. Our observations are useful for testing biogeochemical ocean models and will also help in improving the knowledge of processes and mechanisms behind interannual time-series of bulk components and microorganisms in pelagic and hemipelagic ocean areas.

Avaliação do potencial da fibra e casca de coco maduro, casca de coco verde e cacto pré-tratados visando à produção de etanol

The present work investigated the potential of different residual lignocellulosic materials generated in rural and urban areas (coconut fibre mature, green coconut shell and mature coconut shell), and vegetable cultivated in inhospitable environments (cactus) aimed at the production of ethanol, being all materials abundant in the Northeast region of Brazil. These materials were submitted to pretreatments with alkaline hydrogen peroxide followed by sodium hydroxide (AHP-SHP), autohydrolysis (AP), hydrothermal catalyzed with sodium hydroxide (HCSHP) and alkali ethanol organosolv (AEOP). These materials pretreated were submitted to enzymatic hydrolysis and strategies of simultaneous saccharification and fermentation (SSF) and saccharification and fermentation semi-simultaneous (SSSF) by Saccharomyces cerevisiae, Zymomonas mobilis and Pichia stipitis. It was also evaluated the presence of inhibitory compounds (hydroxymethylfurfural, furfural, acetic acid, formic acid and levulinic acid) and seawater during the fermentative process. Materials pretreated with AHP-SHP have resulted in delignification of the materials in a range between 54 and 71%, containing between 51.80 and 54.91% of cellulose, between 17.65 and 28.36% of hemicellulose, between 7.99 and 10.12% of lignin. Enzymatic hydrolysis resulted in the conversions in glucose between 68 and 76%. Conversion yields in ethanol using SSF and SSSF for coconut fibre mature pretreated ranged from 0.40 and 0.43 g/g, 0.43 and 0.45 g/g, respectively. Materials pretreated by AP showed yields of solids between 42.92 and 92.74%, containing between 30.65 and 51.61% of cellulose, 21.34 and 41.28% of lignin. Enzymatic hydrolysis resulted in glucose conversions between 84.10 and 92.52%. Proceeds from conversion into ethanol using green coconut shell pretreated, in strategy SSF and SSSF, were between 0.43 and 0.45 g/g. Coconut fibre mature pretreated by HCSHP presented solids yields between 21.64 and 60.52%, with increased in cellulose between 28.40 and 131.20%, reduction of hemicellulose between 43.22 and 69.04% and reduction in lignin between 8.27 and 89.13%. Enzymatic hydrolysis resulted in the conversion in glucose of 90.72%. Ethanol yields using the SSF and SSSF were 0.43 and 0.46 g/g, respectively. Materials pretreated by AEOP showed solid reductions between 10.75 and 43.18%, cellulose increase up to 121.67%, hemicellulose reduction up to 77.09% and lignin reduced up to 78.22%. Enzymatic hydrolysis resulted in the conversion of glucose between 77.54 and 84.27%. Yields conversion into ethanol using the SSF and SSSF with cactus pretreated ranged from 0.41 and 0.44 g/g, 0.43 and 0.46 g/g, respectively. Fermentations carried out in bioreactors resulted in yields and ethanol production form 0.42 and 0.46 g/g and 7.62 and 12.42 g/L, respectively. The inhibitory compounds showed negative synergistic effects in fermentations performed by P. stipitis, Z. mobilis and S. cerevisiae. Formic acid and acetic acid showed most significant effects among the inhibitory compounds, followed by hydroxymethylfurfural, furfural and levulinic acid. Fermentations carried out in culture medium diluted with seawater showed promising results, especially for S. cerevisiae (0.50 g/g) and Z. mobilis (0.49 g/g). The different results obtained in this study indicate that lignocellulosic materials, pretreatments, fermentative processes strategies and the microorganisms studied deserve attention because they are promising and capable of being used in the context of biorefinery, aiming the ethanol production.

Extração, caracterização e prospecção de atividades farmacológicas de polissacarídeos sulfatados da macroalga verde Caulerpa prolifera

This study aimed to extract, characterize and conduct a prospective analysis of pharmacological activities of sulfated polysaccharides from green seaweed Caulerpa prolifera. Seven fractions (CP-0.3/CP-0.5/CP-0.7/CP-0.9/CP-1.1/CP-1.5/CP-2.0) were obtained from C. prolifera by alkaline proteolysis followed by sequential precipitation in acetone. The physicochemical analyzes indicated that C. prolifera synthesizes a homogalactan (CP-0.9) and different populations of sulfated heteropolysaccharides. In the analysis of anticoagulant activity, all fractions except CP-0.3, influenced the intrinsic coagulation pathway. All fractions showed antioxidant activity in six different assays being more pronounced in hydrogen peroxide scavenging assay, especially CP-0.3, CP-0.7 and CP-0.9 (which obtained 61% of hydrogen peroxide scavenging), in ferric chelation assay (especially CP-0.9 with 56% chelation) and cupric chelation assay (especially CP-2.0 with 78% chelation). With respect to immunomodulatory activity, the presence of CP-0.3, CP-0.7 and CP-0.9 showed an immunogenic potential, increasing the production of nitric oxide (NO) by 48, 142 and 163 times, respectively. Conversely, the NO synthesis fell 73% after the activation of macrophages by LPS, incubated concurrently with CP-2.0. The anti-adipogenic activity of the fractions was also evaluated and CP-1.5 was able to reduce the differentiation of pre-adipocytes (3T3-L1) into adipocytes by 60%, without affecting the cell viability. The fractions CP-0.3, CP-0.5 and CP-0.9 reduced the viability of the HeLa cells (human cervical adenocarcinoma) by 55% and CP-1.5 reduced the viability of the 786-0 cells (human renal adenocarcinoma) by 75%. Leishmanicidal activity and microbicide effect against Carbapenem-resistant Klebsiella pneumoniae (KPC) have not been identified. However, the viability of Staphylococcus epidermidis was reduced by 23.8% in the presence of CP -1.5. All fractions were able to change the formation of calcium oxalate crystals. CP-0.3, CP-0.5 and CP-1.1 only promoted the formation of COD type crystals with a very small size (1 μm). Confocal microscopy and zeta potential data of crystals formed in the presence of the samples showed that the polysaccharides present in the fractions must interact with calcium ions present throughout the crystal lattice, affecting the growth and morphology of crystals The results described herein indicate that the fractions rich in polysaccharides obtained from the green seaweed C. prolifera present a multi therapeutic potential, and subsequent purification steps, as well as research on the mechanisms of action by which these polymers act should be investigated.

Avaliação da influência de surfactantes químico e biológico na hidrólise enzimática de casca de coco verde após pré-tratamento ácido/alcalino e com peróxido de hidrogênio alcalino

In Brazil many types of bioproducts and agroindustrial waste are generated currently, such as cacashew apple bagasse and coconut husk, for example. The final disposal of these wastes causes serious environmental issues. In this sense, waste lignocellulosic content, as the shell of the coconut is a renewable and abundant raw material in which its use has an increased interest mainly for the 2nd generation ethanol production. The hydrolysis of cellulose to reducing sugars such as glucose and xylose is catalysed by a group of enzymes called cellulases. However, the main bottleneck in the enzymatic hydrolysis of cellulose is the significant deactivation of the enzyme that shows irreversible adsorption mechanism leading to reduction of the cellulose adsorption onto cellulose. Studies have shown that the use of surfactants can modify the surface property of the cellulose therefore minimizing the irreversible binding. The main objective of the present study was to evaluate the influence of chemical and biological surfactants during the hydrolysis of coconut husk which was subjected to two pre-treatment in order to improve the accessibility of the enzymes to the cellulose, removing this way, part of the lignin and hemicellulose present in the structure of the material. The pre-treatments applied to coconut bagasse were: Acid/Alkaline using 0.6M H2SO4 followed by 1M NaOH, and the one with Alkaline Hydrogen Peroxide at a concentration of 7.35% (v/v) and pH 11.5. Both the material no treatment and pretreated were characterized using analysis of diffraction X-ray (XRD), Scanning Electron Microscopy (SEM) and methods established by NREL. The influence of both surfactants, chemical and biological, was used at concentrations below the critical micelle concentration (CMC), and the concentrations equal to the CMC. The application of pre-treatment with coconut residue was efficient for the conversion to glucose, as well as for the production of total reducing sugars, it was possible to observe that the pretreatment fragmented the structure as well as disordered the fibers. Regarding XRD analysis, a significant increase in crystallinity index was observed for pretreated bagasse acid/alkali (51.1%) compared to the no treatment (31.7%), while that for that treated with PHA, the crystallinity index was slightly lower, around 29%. In terms of total reducing sugars it was not possible to observe a significant difference between the hydrolysis carried out without the use of surfactant compared to the addition of Triton and rhamnolipid. However, by observing the conversions achieved during the hydrolysis, it was noted that the best conversion was using the rhamnolipíd for the husk pretreated with acid/alkali, reaching a value of 33%, whereas using Triton the higher conversion was 23.8%. The coconut husk is a residue which can present a high potential to the 2nd generation ethanol production, being the rhamonolipid a very efficient biosurfactant for use as an adjuvant in the enzymatic process in order to act on the material structure reducing its recalcitrance and therefore improving the conditions of access for enzymes to the substrate increasing thus the conversion of cellulose to glucose.
