Este documento resume los resultados conseguidos por Cáritas Española, Cruz Roja Española, Fundación ONCE y Fundación Secretariado Gitano en el Programa Operativo “Lucha contra la Discriminación” del Fondo Social Europeo entre los años 2000 y 2015. Durante estos años estas cuatro entidades han atendido a 850.000 personas vulnerables y en situación de exclusión y han conseguido empleo para 230.000. Además han promovido más de 1.000 iniciativas de creación de empresas y empleo autónomo. Todo ello ha sido posible gracias al apoyo del Gobierno Español, del efecto multiplicador de los recursos propios y del Fondo Social Europeo y a la creación de un entramado de apoyo con una amplia red de empresas e instituciones de todo tipo. Se trata de una iniciativa única en Europa que a lo largo de estos años ha recibido numerosos premios y reconocimientos y a la que la Comisión Europea ha reseñado en múltiples ocasiones como un ejemplo de buenas prácticas y de innovación social. La evaluación independiente de este programa, que ha movilizado casi 700 millones de Euros y que cuenta con un capital humano especializado de 1.600 profesionales y 29.000 voluntarios, ha demostrado que el empleo de estos recursos es una buena inversión social, pues por cada Euro invertido se produce un retorno de 1,4 Euros. Invertir en la inserción socio-laboral de los grupos vulnerables no solamente contribuye a los objetivos de la Estrategia Europa 2020 de aumentar el empleo y reducir la pobreza y exclusión social, sino que además contribuye a aumentar los ingresos públicos vía impuestos y cotizaciones sociales, supone un ahorro en el gasto social y contribuye a la dinamización de la economía. En el actual período de ejecución de 2014-2020, los Reglamentos exigen que el 20% de los recursos del FSE se dedique a personas vulnerables y en exclusión. La experiencia acumulada por estas cuatro entidades y su capacidad para dar respuesta a las necesidades de estos grupos, les sitúa como actores clave en la ejecución de las acciones del nuevo Programa Operativo de Inclusión Social y de la Economía Social.

Esse estudo refere-se à construção da Memória e da Identidade do Sindicato de Trabalhadores em Educação das Redes Pública Estadual e Municipais do Maranhão – SINPROESEMMA, entidade reconhecida oficialmente pela categoria como seu legítimo representante em todo Estado do Maranhão. Reconstruir a Memória e a Identidade do SINPROESEMMA, naqueles que lhe deram origem, pois, a memória permite a relação do corpo presente com o passado e, ao mesmo tempo, interfere no processo “atual” das representações. A memória aparece como força subjetiva ao mesmo tempo profunda e ativa, latente e penetrante. A memória desse sindicato que não deve ser pensada apenas como resgate do passado, mas como marco referencial a partir do qual os docentes, a sociedade acadêmica e a própria comunidade redescobrem valores e experiências. Portanto se a memória e a identidade do SINPROESEMMA forem entendidas como ferramenta de comunicação e de organização dos trabalhadores, então poder-se-á afirmar que se transforma em conhecimento útil a história e a experiência acumulada em sua trajetória. Uma das características da memória, que é essencial ao pesquisador, é o fato de, apesar de resguardar sua dimensão subjetiva, também expressar, no que tange ao SINPROESEMMA, sua constituição de bases coletivas. Este trabalho mostrará como as condições básicas objetivas e subjetivas do mesmo estão relacionadas à luta dos trabalhadores do ensino público das redes municipais e estadual do Estado do Maranhão - Brasil.

The use of cover crops is a fundamental strategy to the weed management in Southern Brazil. In highly infested areas, the herbicides use is increasing, which increases the costs of the crops production as well as the environmental contamination. Oat and velvet bean plants havecontrasting characteristics regarding to residues decomposition speed and the capacity to immobilize Nitrogen in the soil, providing distinct results of weeds suppression throughout the time, and therefore, requiring distinct management strategies before, during, and after the corn crop establishment. The general objective of the experiment was to evaluate the environmental dynamics of the herbicide atrazine, the corn grain yield, and the efficiency of the weed control, considering areas with distinct history regarding the use of mulching, levels of straw and rates of atrazine. For this, the experiment was carried out in two parts: in the first part, two trials with the corn crop were established, one using oat and the other using velvet bean as cover crops. The experimental design used for both field trials was randomized complete blocks arrangement with four replications. The factor A was constituted by four levels of straw (0; 0.75x; 1.5x; 3x) and the factor B was constituted by four rates of the herbicide atrazine (0; 2100; 4200; 8400 g a i. ha-1). Soil samples were collected for greenhouse trialsto determine the persistence. Atrazine leaching evaluation was performed by chromatography using samples collected over the soil profile.In the field, the weed density, the fresh and dry weight and the yield of the corn were evaluated. In the greenhouse trials, the main variables evaluated were plant height and injury caused by the herbicide toxicity. In the second part, soils with distinct covering history were sampled, and the mineralization and sorption studies, both with 14C-atrazine, were conducted in the laboratory. The experimental design was randomized complete blocks arrangement with four replications. The results from the field experiment show that the high levels of straw above ground, isolated, were not efficient to control completely the weeds, and that high levels of velvet bean`s straw decreased the corn potential yield. The greenhouse trials showed that high levels of oat straw prevent the scape of atrazine to soil, this effect of oat straw upon the herbicide availability on soil was detected up to 12 days after spraying. The half-life of atrazine sprayed over oat straw varied from 7 to 14 days after spraying, while the half-life of atrazine sprayed over velvet bean varied from 5 to 14 days after spraying. Increasing oat straw levels presents the capacity to reduce the lixiviation of atrazine in the soil profile, however, this effect was not verified when using velvet bean straw, because the herbicide was not detected in the soil profile, at 21 days after spraying. The chromatographic analysis indicate thatthe atrazine concentrates closer to the soil surface regardless of amount of straw, not being detected deeper than 8 cm in the soil. The accumulated mineralization of 14C-arazine sprayed over V. sativa is superior if compared to soils with S. cereale or non-covered soils. The sorption coefficient of atrazine is superior when sprayed over straw than over the soil.

The goal of this study was to compare areas under different forest restoration technologies in relation to abundance, richness, diversity and composition of the present fauna in the litter and soil. The treatments evaluated were: natural regeneration (RN); high diversity tree plantations (L) and nucleation (N). An area of secondary forest was included in the study as a reference of soil conditions. The experimental design was in randomized block with four replications. Samples were collected for extraction of mesofauna (October/2012; July and October/2013) and macrofauna (June and October/2013) in six points of each plot, totaling 24 samples per treatment. For collecting soil macrofauna was used TSBF method. The mesofauna was collected with a metal cylinder and extracted by Berlese-Tüllgren funnel. Litter and soil were collected separately at each point and the fauna was identified level of class/taxonomic order. The springtails were classified using morphotypes. In total, considering the mesofauna, macrofauna and three times collected were accounted 28618 organisms. In relation soil mesofauna, the evaluated technologies did not differ, after three years of restoration, in relation to total abundance of organisms and community composition. The Shannon diversity index (H), in soil mesofauna, followed a human impact gradient. This index was higher in natural regeneration, which not was undergone technical interventions and showed higher moisture in the soil. The tree planting technology, under the control of volunteer plants in total area, showed lower H index. In the case of litter mesofauna, the technologies did not differ in relation the mean richness, total abundance of organisms and community composition. Considering edaphic macrofauna, technologies did not differ in relation to the abundance and richness, and in the evaluation of June/2013, RN showed higher H index and differed in relation to the community composition of other technologies. In October/2013 evaluation, the differences between the technologies in relation to H index were narrower and these did not differ in terms of composition of soil macrofauna community. In litter macrofauna, in June/2013, the RN presented greater richness and H index when compared to other technologies and in evaluation October/2013 technologies did not differ in relation to community composition, richness and mean abundance of organisms. In the case of springtails, technologies after three years in the restoration process, did not differ in relation to the abundance, richness and composition of Collembola community for different morphotypes. The secondary forest, in relation to forest restoration technologies, presented greater abundance of saprophages, predators and greater diversity of morphotypes of springtails. From these results it, we recommended to natural regeneration by to have the lowest cost of deployment, followed by nucleation and online planting. The animals should be monitored over time, in the restoration technologies, as well as the physical and chemical characteristics of the soil, in order to understand the possible changes in the composition and diversity of organisms.

The proper use of management strategies, such as grazing intensity and nitrogen fertilization are primordial to the success of integrated crop-livestock system. Several studies have demonstrated the influence of grazing intensity and nitrogen fertilization on dynamics of forage production and nutrient cycling. However, most this researches studying these strategies in isolation and little is known about the interaction of these factors in the management of an integrated crop-livestock system. In this context, the aim of this study is to determine the best management strategy involving sward height and nitrogen fertilization, permitting greater forage production and improved efficiency in the use of nitrogen soil by a black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture in integrated crop-livestock system. The experiment was realized in Abelardo Luz – SC, in an area of 14 ha, where has been conducted an experiment in long term with integrated crop-livestock system under no-tillage since 2012. The experimental design is a randomized block design with three replications in a factorial design (2x2), the first factor was the grazing intensity (high and low), characterized by two sward height management (10 and 25 cm), and the second included the time factor application of N in the system: N applied on pasture (N-pasture) and N applied on the culture of grain (N-grain), at dose of 200 kg N ha stocking and variable stocking rate. The previous crop to pasture was corn. The nitrogen fertilization of pasture increased tiller density, forage density, participation of ryegrass ‘Barjumbo’ and percentage of ryegrass leaves in forage mass. Forage mass was less at low sward height on average, however the percentage of ryegrass ‘Barjumbo’ and rye leaves was greater and dead material was lower in this treatment. With nitrogen fertilization of pasture it was possible to double the amount of forage accumulated in periods with further development of ryegrass, furthermore, the total production of DM was increased in 38.4% and the shoot N concentration in 28.6%. When the nitrogen fertilization is applied in pasture, it is possible to keep black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture with an average sward height of 11 cm. The residual effect of N applied at corn was not sufficient to meet the nutritional needs of pasture and the forage production was affected by periods with N deficiency, while a single application of 200 kg N ha was sufficient to meet the N requirements throughout the forage accumulation period. The black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture is efficient in use and recovery of the nitrogen applied in both treatments of sward height.

This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae Rhodophyta) in an organic shrimp pound (Litopenaeus vannamei) under euthrophical conditions. PVC structures (module) witch four ropes laden with 150 g of macroalgae each, were kept during 35 days at three different depths (surface, 10 and 20 cm depth). Wet biomass weighing and environmental parameters (temperature, salinity, turbidity, pH, transparence, precipitation, evaporation, insolation, accumulated solar radiation, nitrite, nitrate, ammonium and orthophosphate) were measured weekly. At all three proposed depths, the macroalgae displayed a higher biomass at the end of experiment than at the initial inoculations. The module kept at a 10 cm depth presented the greatest average biomass (186,3), followed by that kept at 20 cm (180,4 g) and the surface module (169,9 g). Biomass variations showed algae to suffer the direct effects of depths. Biomass loss was associated with the factors that influence light penetration, such as sediment deposits above the thallus, rate of evaporation and precipitation. The smallest loses occurred in the algae kept on surface (0,16%), followed by the algae kept at 20 cm (0,20%) and 10 cm (0,22%). The specific growth rate (SGR) of G. birdiae showed no significant difference between the three depths nor the sample periods. Nevertheless, the modules kept at 10 and 20 cm depths presented similar growth evolution, both growing 0,38%·per day-1, while the module kept on surface had an average SGR of 0,36%·day-1. The models related to growth rate demonstrated temperature, salinity, pH, orthophosphate, ammonium, precipitation and turbidity as the principal environmental parameters influencing the development of G. birdiae

La renovación integral del espacio público y privado de las áreas turísticas maduras se plantea como el elemento de articulación de la política turística. Sin embargo, la experiencia acumulada plantea la necesidad de generar escenarios de buena gobernanza del territorio, en detrimento de la implementación de una estrategia de intervención pública por la vía impositiva de la norma. Para ello, la política pública de las Islas Canarias (España) ha incorporado un singular y novedoso instrumento de ordenación territorial: los “Planes de Modernización, Mejora e Incremento de la Competitividad”. Se trata de planes ad hoc que, con un carácter excepcional, pretenden convertirse en los mecanismos que, vía convenio urbanístico, deben dar cobertura, viabilizar y agilizar la ejecución eficiente de los proyectos de renovación física de los alojamientos turísticos. Sin embargo, la implementación de estos planes no está exenta de complicaciones, las cuales están reduciendo su eficiencia. El principal objetivo de este trabajo es analizar las debilidades y potencialidades de estos instrumentos, susceptibles de ser aplicados a ámbitos turísticos similares.

We conducted a field experiment near Abelardo Luz, Santa Catarina, from October 2012 to April 2014, to evaluate the effect interaction of nitrogen fertilization and height of canopy over the N nutrition of corn subsequently grown to pasture. The data belonging to this thesis are related to the first two production cycles obtained in sorghum pasture (2012/2013), oat (2013) and corn crop (2013/2014). In the evaluation of forage sorghum and oat it was used the same experimental design, consisting of randomized complete block in a factorial arrangement (2 x 2) with three replications. The first factor was considered canopy height (Low and High) and the second factor was the fertilization of cover crop pasture (0 and 200 kg N.ha-1). In phase I and II, the combination of factors evaluators were prepared in the same experimental unit. For corn crop the design was a randomized complete block in a factorial design (2X2X4X6) with three replications. Factors considered in corn were: canopy height of pasture (Low and High), nitrogen application times (NG - nitrogen in the grains and NP - nitrogen in pasture), nitrogen fertilization in corn (0, 100, 200 and 300 kg N.ha-1) and time (46, 53, 60, 67, 76 and 103 days after sowing the maize). In phases I and II, in general the use of N in the pasture increased the productive potential of the pasture and animal management and canopy height has changed the dynamics of structural components and botanical pasture. In cold conditions for long periods and not acclimatized plants the adoption of high nitrogen fertilization and height high grazing pasture leave vulnerable to damage caused by the freezing of plants. The anticipation of nitrogen fertilization on pasture positively affects the corn crop by increasing the accumulated dry matter and N content in the plant. Nitrogen nutritional content of corn with the anticipation of fertilization in pasture is suitable for obtaining high crop production in integrated crop-livestock system. When used nitrogen only coverage in corn sufficiency level in the nitrogen nutrition is achieved with the use of 100 kg N.ha-1. With the use of 200 kg N ha -1 NG and NP no difference in nitrogen content and nitrogen nutrition index.

O nitrogênio e um dos nutrientes mais demandados pelas espécies vegetais, sua presença no solo, sob formas orgânicas ou minerais disponíveis para as plantas, está vinculada à qualidade e quantidade dos resíduos vegetais aportados ao solo. O estudo teve o objetivo de avaliar a influência do cultivo do eucalipto e da acácia na composição das formas orgânicas e inorgânicas de N e, na abundância natural de 15N em um Argissolo Amarelo. Para isso, foram coletadas amostras de solo e serapilheira em monocultivos do Eucalyptus urograndis (clone do Eucalyptus urophylla S. T. Blake x Eucalyptus grandis W. Hill ex Spreng) de ciclo curto (sete anos), sistemas de cultivo de rotação com acácia ( Acacia mangium Willd.) após monocultivo de eucalipto, monocultivo de eucalipto de ciclo longo (24 anos) e mata nativa (Mata Atlântica) como condição original de solo do litoral Norte do Espírito do Santo. Foram avaliados os teores de C orgânico total, N total, N-NH4+, N-NO3-, relação C/N, fracionamento do N orgânico e abundância natural de 15N no solo e serapilheira. Das formas de N-orgânico hidrolisado, o N-amino foi a fração que apresentou maior contribuição (39%), seguida pela fração de N-não identificado (27%), da fração N-amida (18%) e N-hexosamina (15%). O povoamento de acácia promoveu menor abundância natural de 15N e maiores teores de N total e C orgânico no solo e aumentou as formas orgânicas de N-hidrolisado, quando comparado àqueles de eucalipto de ciclo curto. Isso indica o aumento de formas lábeis de N orgânico no solo para as plantas e redução da humificação da matéria orgânica do solo (MOS) de acácia. Nesse sentido, a rotação de cultivos florestais com acácia após eucalipto de ciclo curto contribuiu para o aumento de formas orgânicas no solo, importantes para a nutrição de plantas, por serem potenciais fontes de nutrientes às plantas em curto período de tempo.

This paper aims to verify the Burnout´s possibilities of incidence, finding the creating dimensions and comparing with the socio-demographics characteristics of the researched professionals. This quantitative-descriptive search has a population of 197 workers of 23 nourishing companies in Rio Grande do Norte. This population is predominantly male, younger than 28 years old, single, relatively instructed (57,07% with complete high school) and having just started their current job since 79% of the interviewees are in the company less than six years. The AUDITORIA DO SISTEMA HUMANO (ASH) model, utilized for investigation and developed for the Spaniards Quijano and Navarro in 1999, has several dimensions about human resources management and the organizational effectiveness, but only makes part of the research in 19 questions Burnout referring. It was used factorial analyses with extraction method, varimax rotation and Kaiser normalization with the intuition to define the creating dimensions of the syndrome, they were evaluated with Cronbach Alpha coefficient after extraction. The dimensions found through the factorial analyses were: emotional exhaustion, physical exhaustion and vitality. The accumulated explanation value reached 65,30% of total variation. The data socio-demographics don t justify the syndrome appearance, because the T test and ANOVA showed irrelevant values. It has been also observed that the founded dimensions were different of the Maslach sociopsychological perspective (emotional exhaustion, depersonalization and low professional realization) allowing comparison with others researches and the possibility to develop new ones with workers from different assistance areas. These new researches are important, since the syndrome refers to chronic labor stress consequences and any professional is favorable to Burnout, harmful to the company as to the collaborators

The contribution of green manure to soil improvement and crop production depends primarily on biomass production and its chemical composition, which vary depending on the species, region and growing season. The aim of this research was to evaluate the chemical composition of biomass produced by green manures in Vale do Ribeira, São Paulo, Brazil. In order to develop this research, was carried an experiment in Pariquera-Acu, in 2006/2007, in completely randomized blocks design with four treatments (three green manure and spontaneous vegetation) and five replications. At 30, 60, 90 and 120 after sowing samples were collected in 1m(2) of the shoots and determined fresh and dry, and chemical composition biomass. Sunhemp, pigeon pea and mucuna produced, in decreasing order, the largest quantities of biomass and were more efficient than the spontaneous vegetation. The biomass produced by green manure had higher quality than that produced by spontaneous vegetation. Sunhemp and pigeon pea have a higher proportion of dry matter in stems which have low N, high C/N and L/N ratio, variables indicating slow decomposition of residues. The analysis of dry matter partitioned to better indication of the chemical composition of the residues and the prevision of the availability of nutrients in the soil.
