Assessing perceptions of environmental risk and environmental justice and their impacts on neighborhood attachment in a predominately Hispanic community

This study examines and relates concepts from environmental risk perception and environmental justice and focuses on the perception of environmental problems, their consequent health risks and their impact on neighborhood attachment in a predominately Hispanic community along the U.S.-Mexico border. The findings indicate that the perception of environmental problems in the immediate area varies by problem and demographic subgroup. Ethnicity and income have the highest number of statistically significant associations across ten environmental problems. This result lies in the fact that Hispanics in El Paso County and those with low annual incomes live in neighborhoods that are faced with more severe environmental problems. Thus the findings lend support to the environmental justice claim that the poor and minorities bear the brunt of environmental degradation. ^ The findings also provide evidence that public perception of health risks from an environmental problem is influenced by the perceived severity of an environmental problem in the immediate area. Those who believe the problem is serious on a local level are the ones who are most likely to believe that they could become ill or injured from that problem and that the illness/injury will be serious. ^ The findings of this study also indicate that the young, Hispanics, those who perceive considerable environmental problems in their neighborhood, those who believe that their neighborhood has more environmental problems than others, and those who are angry about those problems are most likely to want to move from their neighborhood. ^ Efforts need to be made to enact policies and programs designed to reduce the environmental hazards in disadvantaged Hispanic communities along the U.S.-Mexico border. Future environmental education campaigns need to complement community-based projects with the media. Programs that involve and empower the community, particularly the youth, in improving the neighborhood could provide a sense of control and pride within their community in solving these problems. These neighborhood improvement efforts could also lead to the development and strengthening of social ties within the community, as well as enhanced community cohesiveness in tackling these problems. ^

Survey on student motivation and approval of educational environment at Universidad Politécnica de Madrid within the European Higher Education area implementation

A recent study elaborated by Vicerrectorado de Ordenación Académica y Planificación Estratégica of Technical University of Madrid (UPM) defines the satisfaction of the university student body as "the response that the University offers to the expectations and demands of service of the students, considered in a general way ". Besides an indicator of academic and institutional insertion of the student, the assessment of student engagement allows us to adapt the academic offer and the extension services of the University to the real needs of the students. The process of convergence towards the European Higher Education Area (EHEA) raises the need to form in competitions, that is to say, of developing in our students capacities and knowledge beyond the purely theoretical-practical thing. Therefore, the perception and experience of the educational process and environment by the students is an important issue to be addressed to accomplish their expectations and achieve a curriculum accordingly to EHEA expectations. The present study aims to explore the student motivation and approval of the educational environment at the UPM. To this end a total of 97 students enrolled in the undergraduate program of Civil Engineering, Computer Engineering and Agronomic Engineering at UPM were surveyed. The survey consisted of 40 questions divided in three blocks. The first one of 20 questions of personal character in that they were gathering, besides the sex and the age, the degree of fulfilment, implication and dedication with the institution and the academic tasks. In the second block we identify 10 questions related to the perception of the student on the teaching quality, and finally a block of 10 questions regarding the Bologna Process. The students personal motivation was moderately high, with a score of 3.6 (all scores are provided on a 5-point scale), being the most valuable items obtaining a university degree (4,3) and the friendship between students (4,2). Any significant difference was shown between sexes (P=0.23) since the averages for this block of questions were of 3.7±0.3 and 3.5±0.4 for women and men respectively. The students are moderately satisfied with their graduate studies with an average score of 3,2, being the questions that reflect a minor satisfaction the research profile of the teachers (2,8) and the organization of the Schools (2,9). The best valued questions are related to the usefulness and quality of the degrees, with 3,5 and 3,4 respectively, and to the interest of the courses within the degree (3,4). For sexes, the results of this block of questions are similar (3.1±0.3 and 3.2±0.3 for men and women respectively=0.79). Also, there were no differences (P=0.39) between the students who arrange work and studies or do not work (3.1±0.2 and 3.2±0.3 respectively). In conclusion, students at UPM present an acceptable degree of motivation and satisfaction with regard to the studies and services that offer their respective Schools. Both characteristics receive the same value both for men and for women and so much for students who arrange work and studies as for those who devote themselves only to studying. In a significant way, students who are more engaged and are in-class attendants present the major degree of satisfaction.Overall, there is a great lack of information regarding the Bologna Process. In fact to the majority, they would like to know more on what it is, what it means and what changes will involve its implementation.

Conservación de plantas regeneradas in vitro y análisis de la variación somaclonal de Cinchona officinalis, Linneo

Cinchona officinalis (Rubiaceae), especie endémica del Valle de Loja, ubicado en la región sur del Ecuador, es un recurso forestal de importancia medicinal y ecológica, además la especie ha sido catalogada como planta nacional y es un ícono de la región sur por su aporte a la farmacopea mundial. Esta especie, entre los siglos XVII-XIX sufrió una gran presión en sus poblaciones debido a la extracción masiva de la corteza para la cura del paludismo. Aunque la actividad extractiva generó grandes ingresos a la Corona Española y a la región Sur del Ecuador, ésta fue poco o nada sustentable ecológicamente, provocando la desaparición de la especie en muchos sitios de la provincia, pues, en su momento, no se consideraron alternativas de recuperación de las poblaciones naturales. Actualmente la extracción y consumo de la corteza en la zona de origen es baja o nula, sin embargo esta zona enfrenta nuevas amenazas. La deforestación a causa de proyectos de desarrollo en infraestructuras, la práctica de actividades agrícolas y de ganadería, y los efectos del cambio climático han ocasionado, en estos últimos años, la fragmentación de los ecosistemas. La mayoría de los bosques del sur del Ecuador se han convertido en parches aislados (los bosques en los que se distribuye C. officinalis no son la excepción) siendo esta la principal causa para que la especie se encuentre en estado de amenaza. Los individuos de la especie tienen una alta capacidad de rebrote y producen semillas durante todo el año; sin embargo la capacidad germinativa y la tasa de sobrevivencia son bajas, además de estas dificultades la especie requiere de la asociación con otras especies vegetales para su desarrollo, lo cual ha limitado su distribución en pequeños parches aislados. Con esta problemática, la recuperación natural de las poblaciones es una necesidad evidente. Varios trabajos y esfuerzos previos se han realizado a nivel local: i. Identificación de la distribución actual y potencial; ii. Determinación de la fenología y fructificación iii. Programas de educación ambiental, iv. Análisis moleculares para determinar la diversidad genética. v. Ensayos de propagación vegetativa; y otras acciones de tipo cultural. No obstante, el estado de conservación y manejo de las poblaciones naturales no ha mejorado significativamente, siendo necesaria la aplicación de estrategias integradas de conservación in situ y ex situ, que permitan la recuperación y permanencia de las poblaciones naturales a largo plazo. El presente trabajo tiene como fin dar alternativas para el cultivo de tejidos in vitro de Cinchona officinalis centrados en la propagación masiva a partir de semillas, análisis de la fidelidad genética y alternativas de conservación de tejidos. Los objetivos específicos que se plantean son: i. Analizar el proceso de germinación y proliferación in vitro. ii. Evaluar la estabilidad genética en explantes cultivados in vitro, mediante marcadores ISSR. iii. Establecer protocolos de conservación in vitro mediante limitación del crecimiento y criopreservación de segmentos nodales y yemas. Los resultados más significativos de esta investigación fueron: i. El desarrollo de protocolos eficientes para mejorar los porcentajes de germinación y la proliferación de brotes en explantos cultivados in vitro. Para evaluar el efecto de los fenoles sobre la germinación, se determinó el contenido total de fenoles y el porcentaje de germinación en semillas de C. officinalis comparados con una especie de control, C. pubescens. Para inducir a proliferación, se utilizaron segmentos nodales de plántulas germinadas in vitro en medio Gamborg (1968) suplementado con diferentes combinaciones de reguladores de crecimiento (auxinas y citoquininas). Los resultados obtenidos sugieren que el contenido de compuestos fenólicos es alto en las semillas de C. officinalis en comparación con las semillas de C. pubescens. Estos fenoles pueden eliminarse con peróxido de hidrógeno o con lavados de agua para estimular la germinación. La formación de nuevos brotes y callos en la mayoría de las combinaciones de reguladores de crecimiento se observó en un período de 45 días. El mayor porcentaje de proliferación de brotes, formación de callos y presencia de brotes adventicios se obtuvo en medio Gamborg (B5) suplementado con 5.0 mg/l 6-bencil-aminopurina y 3.0 mg/l de ácido indol-3-butírico. ii. La evaluación de la fidelidad genética de los explantes obtenidos con distintas combinaciones de reguladores de crecimiento vegetal y diversos subcultivos. Se realizó el seguimiento a los explantes obtenidos de la fase anterior, determinando el índice de multiplicación y analizando la fidelidad genética de los tejidos obtenidos por las dos vías regenerativas: brotación directa y regeneración de brotes a partir de callos. Este análisis se realizó por amplificación mediante PCR de las secuencias ubicadas entre microsatélites-ISSR (Inter simple sequence repeat). El medio Gamborg (B5) con 3.0 mg/l de AIB y 5.0 mg/l de BAP usado como medio de inducción en la primera etapa de cultivo generó el mayor índice de proliferación (11.5). Un total de 13 marcadores ISSR fueron analizados, 6 de éstos fueron polimórficos. El mayor porcentaje de variación somaclonal fue inducido en presencia de 1.0 mg/l 2,4-D combinado con 0.2 mg/l Kin con un 1.8% en el segundo sub-cultivo de regeneración, la cual incrementó a 3.6% en el tercer sub-cultivo. Todas las combinaciones con presencia de 2,4-D produjeron la formación de callos y presentaron variación genética. Por su parte la fidelidad genética se mantuvo en los sistemas de propagación directa a través de la formación de brotes a partir de meristemos preformados. iii. El establecimiento de protocolos de conservación in vitro y crioconservación de segmentos nodales y yemas. Para la conservación limitando el crecimiento, se cultivaron segmentos nodales en los medios MS y B5 en tres concentraciones de sus componentes (25, 50 y 100%); y en medio B5 más agentes osmóticos como el manitol, sorbitol y sacarosa en diferentes concentraciones (2, 4 y 8%); los cultivos se mantuvieron por 12 meses sin subcultivos. Para el establecimiento de protocolos para la crioconservación (paralización del metabolismo) se usaron yemas axilares y apicales a las cuales se les aplicaron los métodos de encapsulación-deshidratación y vitrificación. La efectividad de los protocolos usados se determinó en función de la sobrevivencia, reducción del crecimiento y regeneración. Los resultados obtenidos en este apartado reflejan que un crecimiento limitado puede mantener tejidos durante 12 meses de almacenamiento, usando medio B5 más manitol entre 2 y 8%. En los protocolos de crioconservación, se obtuvo el mayor porcentaje de recuperación tras la congelación en NL en el tratamiento control seguido por el método crioprotector de encapsulación-deshidratación. Este trabajo brinda alternativas para la propagación de C. officinalis bajo condiciones in vitro, partiendo de material vegetal con alta diversidad genética. El material propagado puede ser fuente de germoplasma para la recuperación y reforzamiento de las poblaciones naturales así como una alternativa de producción para las comunidades locales debido a la demanda actual de corteza de la zona de origen para la elaboración de agua tónica. ABSTRACT Cinchona officinalis (Rubiaceae) is endemic to the Loja Valley, located in the southern area of Ecuador. The importance of this plant as medical and ecological resource is so great that it has been designated as the national flower and is an icon of the southern region for its contribution to the world pharmacopoeia. Between XVII-XIX centuries its population suffered great reduction due to massive harvesting of the bark to cure malaria. Although extraction activity generated large revenues to the Spanish Crown and the southern region of Ecuador, this was not ecologically sustainable, causing the disappearance of the species in many areas of the province, because during that time alternatives to prevent extinction and recover natural populations were not taken in account. Currently the extraction and consumption of bark in the area of origin is almost absent, but this species faces new threats. Deforestation due to infrastructure development, the practice of farming and ranching, and the effects of climate change had led to the fragmentation of ecosystems during the recent years. Most of the forests of southern Ecuador have become isolated patches, including those where C. officinalis is diffused. The lack of suitable habitat is today the main threat for the species. The species has a high capacity for regeneration and produces seeds throughout the year, but the germination rate is low and the growth is slow. In addition, the species requires the association with other plant species to develop. All these factors had limited its distribution to small isolated patches. The natural recovery of populations is essential to face this problem. Several studies and previous efforts had been made at local level: i. Identification of current and potential distribution; ii. Phenology determination. iii. Environmental education programs, iv. Molecular analisis to determine the genetic diversity. v. Testing of vegetative propagation; and other actions of cultural nature. Despite these efforts, the state of conservation and management of natural populations has not improved significantly. Implementation of integrated in situ and ex situ conservation strategies for the recovery and permanence of long-term natural populations is still needed. This work aims to provide alternatives for in vitro culture of tissue of Cinchona officinalis focused on mass propagation from seeds, genetic fidelity analysis and tissue conservation alternatives. The specific aims are: i. Analyze the process of germination and proliferation in vitro. ii. To evaluate the genetic stability of the explants cultured in vitro by ISSR markers. iii. Establish protocols for in vitro conservation by limiting growth and cryopreservation of nodal segments and buds. The most significant results of this research were: i. The development of efficient protocols to improve germination rates and proliferation of buds in explants cultured in vitro. To study the effect of phenols on germination, the total phenolic content and percentage germination was measured in C. officinalis and in a control species, C. pubescens, for comparison. The content of phenolic compounds in C. officinalis seeds is higher than in C. pubescens. These phenols can be removed with hydrogen peroxide or water washes to stimulate germination. To analyze the regeneration, we used nodal explants from seedlings germinated in vitro on Gamborg medium (1968) supplemented with different combinations of growth regulators (auxins and cytokinins) to induce proliferation. The formation of new shoots and calluses was observed within a period of 45 days in most combinations of growth regulators. The highest percentage of shoot proliferation, callus formation and adventitious buds were obtained in B5 medium supplemented with 5.0 mg/l 6-benzyl-aminopurine and 3.0 mg/l indole-3-butyric acid. ii. Evaluating genetic fidelity explants obtained with various combinations of plant growth regulators and different subcultures. The genetic fidelity was analyzed in tissues obtained by the two regenerative pathways: direct sprouting and shoot regeneration from callus. This analysis was performed by PCR amplification of the sequences located between microsatellite-ISSR (Inter Simple Sequence Repeat). Among a total of 13 ISSR markers analyzed, 6 were polymorphic. The highest percentage of somaclonal variation was induced in the presence of 1.0 mg/l 2,4-D combined with 0.2 mg/l Kin with 1.8% in the second round of regeneration, and increased to 3.6% in the third round. The presence of 2,4-D induced genetic variation in all the combinations of growth regulators. Meanwhile genetic fidelity remained systems propagation through direct shoot formation from meristems preformed. iii. Establishing conservation protocols in vitro and cryoconservation of nodal segments and buds. For medium-term conservation (limited growth) nodal segments were cultured in MS and B5 media at three concentrations (25, 50 and 100%); we tested B5 medium with different concentrations of osmotic agents such as mannitol, sorbitol and sucrose (2, 4 and 8%); cultures were maintained for 12 months with regular subculturing. To establish protocols for cryoconservation (cessation of metabolism) different methods of encapsulation-dehydration and vitrification were applied to axillary and apical buds. The effectiveness of the used protocols is determined based on the survival, growth and regeneration success. The results show that these tissues can be maintained in storage for 12 months, using B5 medium plus mannitol between 2 and 8%. The cryoconservation protocol with highest percentage of recovery was obtained by contral treatment, followed by freezing in NL with encapsulation-dehydration method. This work provides alternatives for the propagation in vitro of C. officinalis, starting from plant material with high genetic diversity. The obtained material represents a source of germplasm to support the recovery and strengthening of natural populations as well as a creation of alternative sources for local communities due to the current demand of bark for the preparation of tonic water.

Estratégias para operacionalização da logística reversa de medicamentos

O descarte de medicamentos envolve dois fluxos: o fluxo institucional, dos resíduos de fármacos, classificados como resíduos de serviços de saúde, utilizados na indústria e nas instituições de saúde; e o fluxo domiciliar, dos medicamentos vencidos/em desuso em poder da população. O descarte dos resíduos de medicamentos de origem domiciliar pode ser promovido pela logística reversa, onde este tipo de resíduo é devolvido ao setor empresarial para destinação final ambientalmente segura. O objetivo deste estudo foi identificar as estratégias mais viáveis para operacionalização da logística reversa de medicamentos. Trata-se de uma pesquisa exploratória, descritiva, com abordagem quantitativa. As estratégias foram avaliadas junto a atores da cadeia de valor farmacêutica: representantes do poder público, da indústria e distribuição farmacêutica, e consumidores/potenciais consumidores de medicamentos. Foram elaborados três questionários de avaliação de estratégias segundo seis critérios: mediação (articulação entre atores da cadeia produtiva farmacêutica por meio de políticas públicas); fiscalização (das ações); complexidade (de implantação e operacionalização); custos (de implantação e manutenção); adesão (potencialidade de ser inserida no cotidiano da população) e abrangência (potencialidade de alcançar a população). As estratégias foram hierarquizadas em ordem decrescente de viabilidade: rientações à população por profissionais de saúde, farmácias e internet, sinalização de informações nas embalagens e bulas de medicamentos, campanhas publicitárias e de educação ambiental e a disponibilização de postos de entrega voluntária. Os resultados poderão contribuir para a operacionalização de um sistema de logística reversa de medicamentos, considerando todos os atores envolvidos e buscando conciliar suas necessidades, possibilidades, limitações e interesses

Igualdades e diferenças nas políticas educacionais: a agenda das diversidades nos governos Lula e Dilma

Esta pesquisa aborda as chamadas políticas de diversidade na educação e sua contribuição para o reconhecimento e a promoção dos direitos humanos e a superação do racismo, do sexismo, da homofobia e das demais desigualdades e discriminações que marcam profundamente a sociedade e a educação brasileiras. Com base nas vozes de gestores/as públicos/as e ativistas da sociedade civil, na análise documental e da execução orçamentária e na experiência política da pesquisadora, é apresentado um balanço sobre os dez anos de existência da Secretaria de Educação Continuada, Alfabetização e Diversidade (Secad), órgão do Ministério da Educação criado no primeiro governo do Presidente Luiz Inácio Lula da Silva. Em especial, buscou-se identificar as provocações e os tensionamentos gerados pelas agendas das diversidades para o atual desenho, funcionamento e institucionalidade das políticas educacionais e sua influência nas concepções de qualidade educacional em disputa nas políticas federais. Essas disputas estiveram presentes nas Conferências Nacionais de Educação e no processo conflitivo de tramitação do novo Plano Nacional de Educação (Lei Federal n. 13.005/2014), analisados neste trabalho. Respaldado por convenções e pelas resoluções internacionais das Conferências da ONU e por normativas nacionais, o debate sobre diferenças ganhou espaço na agenda das políticas educacionais brasileiras. Essa discussão foi impulsionada por movimentos sociais negros, indígenas, LGBTs, feministas, de trabalhadores do campo, de pessoas com deficiências, de quilombolas, ambientalistas e por agendas de fronteira na efetividade do direito humano à educação, como a educação de jovens e adultos, a educação em territórios de alta vulnerabilidade social e a educação de pessoas privadas de liberdade, entre outras. Apresenta-se, neste trabalho, uma contribuição teórica ao debate sobre a relação entre qualidade educacional, diferenças e igualdades, com base nas teorias críticas de justiça social. Discutem-se as possibilidades de a noção da diversidade constituir uma resposta interseccional às múltiplas discriminações e desigualdades que atingem os sujeitos concretos no cotidiano da vida e, especificamente, nas instituições educacionais. Ao final da tese, embasadas na definição do contexto de estratégia política de Stephen Ball e nas contribuições para o aperfeiçoamento das políticas 14 previstas na metodologia de análise das políticas públicas, são apresentadas reflexões comprometidas com a ampliação da capacidade das políticas educacionais no sentido de dar respostas a essas agendas, em uma perspectiva de promoção da justiça na educação no marco dos direitos humanos.

Desenvolvimento sustentável: a educação e o ambiente

O desenvolvimento sustentável é um tema atual que tem despertado preocupações e crescente interesse social. A acentuada explosão demográfica nos anos 50 pôs em causa a relação entre a sociedade e o ambiente. Este estudo tem como objetivo sensibilizar a comunidade educativa para os problemas ambientais e contribuir para a formação de cidadãos ambientalmente cultos e globalmente intervenientes. Utilizou-se como metodologia a pesquisa bibliográfica através de livros, revistas e fontes eletrónicas. O aumento da população mundial e a intervenção antrópica, são as principais causas dos problemas ambientais. Em Portugal, o desenvolvimento sustentável e a educação ambiental são temáticas abordadas nos vários anos de escolaridade, numa perspetiva horizontal e vertical.
