O presente artigo resume uma dissertação de Mestrado em Segurança e Higiene do Trabalho. Foi feito um estudo da implementação das Medidas de Autoproteção (MAP) contra incêndio, numa escola de ensino básico e secundário, cujo edifício é isolado, com três pisos e comporta 952 pessoas. Teve como objetivos contribuir para a melhoria dos resultados em situações de emergência, da cultura de segurança e da resiliência. A concretização deste estudo implicou reuniões com o Delegado de Segurança (DS) da instituição, visitas de reconhecimento às instalações, análise de documentação existente, elaboração de documentação auxiliar, programação de ações de sensibilização e de simulação, com envolvimento de meios. A metodologia baseou-se na observação participante, com recurso a gravações de vídeo das atividades desenvolvidas, para posterior análise. No fim do estudo, concluiu-se que os Agentes de Segurança (AS) não estariam, à partida, capacitados para desempenhar as respetivas funções nas MAP. Verificou-se, ainda assim, ser possível desenvolver-lhes algumas competências, mediante informação, formação e treino, que vieram iniciar os AS em matérias de combate ao incêndio, evacuação e primeiros socorros, bem como sensibilizar para as consequências a que se podem expor, para a necessidade de controlo emocional e comunicação eficaz, em situação de emergência. / This article summarizes a master course thesis in Health and Safety at Work. A study was made about the implementation of Measures of Fire Self-Protection (MAP) in a school of basic and secondary education, whose building is isolated, with three floors and accommodates 952 persons. The study aimed to improve results in emergency situations, safety culture and resilience. Such objectives required meetings with the School Safety Officer (DS), reconnaissance visits to facilities, analysis of existing documentation, preparation of auxiliary documentation and awareness-raising actions programming and simulation, as well as the allocation of their resources. The methodology was based on participant observation, with the use of video recordings of activities for later analysis. At the end of the study it was found that the Safety Agents (AS), at the beginning, would not be able to carry out their functions in the MAP. Still, it was found to be possible to develop in them some skills, through information, education and training, which initiated the agents in matters of fire fighting, evacuation and first aid, as well as raised their awareness of the consequences to which they may be exposed, to the need for emotional control and effective communication, in an emergency situation.

O presente relatório caracteriza a ação política e a perspetiva social da Junta de Freguesia de São Domingos de Benfica, categorizando-o em cinco eixos de intervenção, analisando a sua eficácia e abrangência no período entre 2005 e 2011. No primeiro eixo, focado na ação na infância e juventude, inclui-se o Programa de Promoção de Competências Pessoais e Sociais, o Gabinete de Apoio à Criança e ao Jovem, os Encontros para Pais, a Comissão de Proteção de Crianças e Jovens, as Atividades de OTL do Espaço Jovem e os Programas de Férias. Das respostas para os adultos, no segundo eixo, fazem parte dois gabinetes de apoio aos munícipes1 com perturbações de comportamento aditivo e vítimas de violência doméstica, incluindo-se ações de prevenção e sensibilização. Para a população idosa temos o terceiro eixo e salienta-se o Programa de Envelhecimento Ativo e Saudável, as Atividades de OTL, nomeadamente o Programa de Férias para a população Sénior e as visitas e passeios histórico-culturais. A família e a qualidade das relações familiares são um aspeto de grande importância, por isso temos o quarto eixo que tem o acompanhamento psicossocial, apoio a famílias carenciadas e o projeto de apoio às famílias junto de bairros isolados da freguesia. Finalmente, o quinto e último eixo refere-se a um movimento de integração das várias entidades da freguesia designado por Comissão Social de Freguesia que pretende desenvolver projetos orientados para o apoio à comunidade. Este relatório terminará com uma reflexão crítica relativamente à evolução do trabalho desenvolvido na ação social desde 2005 até 2011.

A presente pesquisa analisa a Gestão da Assistência Social no Município de Bujaru, no período de 2009 à 2011, de forma crítica, evidenciando os avanços, as dificuldades e os desafios, enfrentados pelo órgão de assistência social – SEMTEPS – Secretaria Municipal de Trabalho e Promoção Social. Que foi criada para coordenar as políticas sociais e consolidar o tripé: Conselho, Plano e Fundo como partes de um todo, denominado de Sistema Único de Assistência Social, integrado e indissociável, fundamental para a qualidade da gestão e operacionalização dos serviços socioassistenciais. Considerando que no Plano Municipal de Assistência Social de 2011/2012 e suas modificações, observou-se que as ações relativas à assistência social em Bujaru, de modo geral, apresentaram-se tímidas, com base nos limites previstos na LOAS. Pois, embora não seja esta uma dificuldade específica, o reconhecimento do Município enquanto lócus das políticas sociais ainda não acontece de forma sistemática. E, para compreender esta realidade local, por meio de observações, visitas e análises bibliográficas foi necessário resgatar um pouco do histórico da assistência social no Brasil, seus princípios e diretrizes, regulamentadas pela LOAS, e, como esta política em constante inovação e evolução se efetiva, também, em Portugal.

El escritor Miguel Donoso Pareja confiesa que en su vida existieron dos modelos: el de su padre -hasta reconocer que no era capaz de emular al navegante y matemático-, y el de su tío Alfredo Pareja. Admira al escritor tanto como al ser humano: por su deseo permanente de aprender y la exigencia implacable consigo mismo, cuanto por su vitalidad. Recuerda las visitas familiares, cada semana, de su tío a la Península de Santa Elena, aprobaba en silencio las lecturas juveniles de Donoso, e impuso un quiebre de calidad con Las mil noches y una noche. Como estudiante en casa de su abuela materna en Guayaquil, el autor conoció a otro Alfredo Pareja: el de su agitada rutina diaria de escritor y hombre de negocios, visitaba su casa, fascinado por su inmensa biblioteca, a la que tenía libre acceso, poco después, su tío Alfredo iniciaría sus largos años de viajero, y se reencontrarían pocas veces, en Quito, en la década de 1980. El autor concluye la emotiva reseña con una breve síntesis valorativa de la producción de Pareja Diezcanseco.

Worldwide marine protected areas (MPAs) have been designated to protect marine resources, including top predators such as seabirds. There is no conclusive information on whether protected areas can improve population trends of seabirds when these are further exploited as tourist attractions, an activity that has increased in past decades. Humboldt Penguins (Spheniscus humboldti) and Magellanic Penguins (S. magellanicus) breed sympatrically on Puñihuil Islets, two small coastal islands off the west coast of Chiloé Island (41° S) in southern Chile that are subject to exploitation for tourism. Our goal was to compare the population size of the mixed colony of Humboldt and Magellanic Penguins before and after protection from unregulated tourism and freely roaming goats in 1997. For this purpose, two censuses were conducted in 2004 and 2008, and the numbers compared with those obtained in 1997 by other authors. The proportion of occupied, unoccupied, and collapsed/flooded burrows changed between years; there were 68% and 34% fewer collapsed burrows in 2004 and 2008, respectively, than in 1997. For the total number of burrows of both species, we counted 48% and 63% more burrows in 2004 and 2008, respectively, than in 1997. We counted 13% more burrows of Humboldt Penguins in 2008 than in 1997, and for Magellanic Penguins, we estimated a 64% increase in burrows in 2008. Presumably, this was as a result of habitat improvement attributable to the exclusion of tourists and the removal of goats from the islets. Although tourist visits to the islets are prohibited, tourism activities around the colonies are prevalent and need to be taken into account to promote appropriate management.

Organic farming has often been found to provide benefits for biodiversity, but the benefits can depend on the species considered and characteristics of the surrounding landscape. In an intensively farmed area of Northeast Italy we investigated whether isolated organic farms, in a conventionally farmed landscape, provided local benefits for insect pollinators and pollination services. We quantified the relative effects of local management (i.e. the farm system), landscape management (proportion of surrounding uncultivated land) and interactions between them. We compared six organic and six conventional vine fields. The proportion of surrounding uncultivated land was calculated for each site at radii of 200, 500, 1000 and 2000 m. The organic fields did not differ from the conventional in their floral resources or proportion of surrounding uncultivated land. Data were collected on pollinator abundance and species richness, visitation rates to, and pollination of experimental potted plants. None of these factors were significantly affected by the farming system. The abundance of visits to the potted plants in the conventional fields tended to be negatively affected by the proportion of surrounding uncultivated land. The proportion fruit set, weight of seeds per plant and seed weight in conventional and organic fields were all negatively affected by the proportion of surrounding uncultivated land. In vine fields the impact of the surrounding landscape was stronger than the local management. Enhancement of biodiversity through organic farming should not be assumed to be ubiquitous, as potential benefits may be offset by the crop type, organicmanagement practices and the specific habitat requirements in the surrounding landscape.

1. Habitat fragmentation can affect pollinator and plant population structure in terms of species composition, abundance, area covered and density of flowering plants. This, in turn, may affect pollinator visitation frequency, pollen deposition, seed set and plant fitness. 2. A reduction in the quantity of flower visits can be coupled with a reduction in the quality of pollination service and hence the plants’ overall reproductive success and long-term survival. Understanding the relationship between plant population size and⁄ or isolation and pollination limitation is of fundamental importance for plant conservation. 3. Weexamined flower visitation and seed set of 10 different plant species fromfive European countries to investigate the general effects of plant populations size and density, both within (patch level) and between populations (population level), on seed set and pollination limitation. 4. Wefound evidence that the effects of area and density of flowering plant assemblages were generally more pronounced at the patch level than at the population level. We also found that patch and population level together influenced flower visitation and seed set, and the latter increased with increasing patch area and density, but this effect was only apparent in small populations. 5. Synthesis. By using an extensive pan-European data set on flower visitation and seed set we have identified a general pattern in the interplay between the attractiveness of flowering plant patches for pollinators and density dependence of flower visitation, and also a strong plant species-specific response to habitat fragmentation effects. This can guide efforts to conserve plant–pollinator interactions, ecosystem functioning and plant fitness in fragmented habitats.

Rationalizing non-participation as a resource deficiency in the household, this paper identifies strategies for milk-market development in the Ethiopian highlands. The additional amounts of covariates required for Positive marketable surplus -'distances-to market'-are computed from a model in which production and sales are correlated; sales are left-censored at some Unobserved thresholds production efficiencies are heterogeneous: and the data are in the form of a panel. Incorporating these features into the modeling exercise ant because they are fundamental to the data-generating environment. There are four reasons. First, because production and sales decisions are enacted within the same household, both decisions are affected by the same exogenous shocks, and production and sales are therefore likely to be correlated. Second. because selling, involves time and time is arguably the most important resource available to a subsistence household, the minimum Sales amount is not zero but, rather, some unobserved threshold that lies beyond zero. Third. the Potential existence of heterogeneous abilities in management, ones that lie latent from the econometrician's perspective, suggest that production efficiencies should be permitted to vary across households. Fourth, we observe a single set of households during multiple visits in a single production year. The results convey clearly that institutional and production) innovations alone are insufficient to encourage participation. Market-precipitating innovation requires complementary inputs, especially improvements in human capital and reductions in risk. Copyright (c) 20 08 John Wiley & Sons, Ltd.

We evaluate the profitability and technical efficiency of aquaculture in the Philippines. Farm-level data are used to compare two production systems corresponding to the intensive monoculture of tilapia in freshwater ponds and the extensive polyculture of shrimps and fish in brackish water ponds. Both activities are very lucrative, with brackish water aquaculture achieving the higher level of profit per farm. Stochastic frontier production functions reveal that technical efficiency is low in brackish water aquaculture, with a mean of 53%, explained primarily by the operator's experience and by the frequency of his visits to the farm. In freshwater aquaculture, the farms achieve a mean efficiency level of 83%. The results suggest that the provision of extension services to brackish water fish farms might be a cost-effective way of increasing production and productivity in that sector. By contrast, technological change will have to be the driving force of future productivity growth in freshwater aquaculture.

The diversity of social bees was assessed at 15 sites across five locations of the Nilgiri Biosphere Reserve, Western Ghats, India, from January to December 2007. We also conducted floristic analyses of local vegetation in each site using one-hectare sample plots. All woody species with a dbh (diameter at breast height) : 30 cm were recorded within the plots. A total area of 9.72 ha was assessed for floristic composition. Similarity of floristic composition between sites was determined using the Jaccard's distance measure and a dendrogram constructed based on the hierarchical clustering of floristic dissimilarities between sites. A Bee Importance Index (BII) was developed to give a measure of the bee diversity at each site. This index was a sum of the species richness of bee species in a site and their visitation frequencies to flowers, calculated as mean flower visits hour 1 within 2 focal patches within one hectare plots. The visits of bee species to flowers were also recorded. The Jaccard distance measure indicated that the montane sites were quite dissimilar to the low elevation sites in floristic diversity. The BII was 7-9 for the wet forest sites and ranged from 4-6 for drier forest sites. Seventy three plant species were identified as social bee plants and of them 45% were visited by one species of bee, 37% by two bee species and 18% by more than two bee species, indicating a certain degree of floral specialization among bees.

We examined the effect of the invasive Solanum elaeagnifolium (Solanaceae) on flower visitation patterns and seed set of the co-flowering native Glaucium flavum (Papaveraceae). We observed flowering G. flavum plants in invaded and uninvaded sites and found that G. flavum flowers in uninvaded sites received significantly more total visits. In addition, we hand-pollinated flowers on plants of G. flavum with (i) pure conspecific pollen, (ii) pure S. elaeagnifolium pollen and (iii) three different mixtures of the two types of pollen (containing 25, 50 and 75% invasive pollen). As a control, flowers were left unmanipulated or were permanently bagged. Seed set did not differ significantly between flowers receiving pollen mixtures and pure conspecific pollen. However, in the open pollination treatment, seed set was significantly lower than in the 100% conspecific pollen treatment, which suggests pollen limitation. Bagged flowers had very low seed set. G. flavum was generally resilient against the deposition of S. elaeagnifolium pollen.

P>1. Ants show complex interactions with plants, both facultative and mutualistic, ranging from grazers through seed predators and dispersers to herders of some herbivores and guards against others. But ants are rarely pollinators, and their visits to flowers may be detrimental to plant fitness. 2. Plants therefore have various strategies to control ant distributions, and restrict them to foliage rather than flowers. These 'filters' may involve physical barriers on or around flowers, or 'decoys and bribes' sited on the foliage (usually extrafloral nectaries - EFNs). Alternatively, volatile organic compounds (VOCs) are used as signals to control ant behaviour, attracting ants to leaves and/or deterring them from functional flowers. Some of the past evidence that flowers repel ants by VOCs has been equivocal and we describe the shortcomings of some experimental approaches, which involve behavioural tests in artificial conditions. 3. We review our previous study of myrmecophytic acacias, which used in situ experiments to show that volatiles derived from pollen can specifically and transiently deter ants during dehiscence, the effects being stronger in ant-guarded species and more effective on resident ants, both in African and Neotropical species. In these plants, repellence involves at least some volatiles that are known components of ant alarm pheromones, but are not repellent to beneficial bee visitors. 4. We also present new evidence of ant repellence by VOCs in temperate flowers, which is usually pollen-based and active on common European ants. We use these data to indicate that across a wide range of plants there is an apparent trade-off in ant-controlling filter strategies between the use of defensive floral volatiles and the alternatives of decoying EFNs or physical barriers.

Hunting foxes with hounds has been a countryside pursuit in Britain since the 17th Century, but its effect nationally on habitat management is little understood by the general public. A survey questionnaire was distributed to 163 mounted fox hunts of England and Wales to quantify their management practices in woodland and other habitat. Ninety-two hunts (56%), covering 75,514 km(2), returned details on woodland management motivated by the improvement of their sport. The management details were verified via on-site visits for a sample of 200 woodlands. Following verification, the area of woodlands containing the management was conservatively estimated at 24,053 (+/- 2241) ha, comprising 5.9% of woodland area within the whole of the area hunted by the 92 hunts. Management techniques included: tree planting, coppicing, felling, ride and perimeter management. A case study in five hunt countries in southern England examined, through the use of botanical survey and butterfly counts, the consequences of the hunt management on woodland ground flora and butterflies. Managed areas had, within the last 5 years, been coppiced and rides had been cleared. Vegetation cover in managed and unmanaged sites averaged 86% and 64%, respectively, and managed areas held on average 4 more plant species and a higher plant diversity than unmanaged areas (Shannon index of diversity: 2.25 vs. 1.95). Both the average number of butterfly species (2.2 vs. 0.3) and individuals counted (4.6 vs. 0.3) were higher in the managed than unmanaged sites.

We describe a Bayesian method for investigating correlated evolution of discrete binary traits on phylogenetic trees. The method fits a continuous-time Markov model to a pair of traits, seeking the best fitting models that describe their joint evolution on a phylogeny. We employ the methodology of reversible-jump ( RJ) Markov chain Monte Carlo to search among the large number of possible models, some of which conform to independent evolution of the two traits, others to correlated evolution. The RJ Markov chain visits these models in proportion to their posterior probabilities, thereby directly estimating the support for the hypothesis of correlated evolution. In addition, the RJ Markov chain simultaneously estimates the posterior distributions of the rate parameters of the model of trait evolution. These posterior distributions can be used to test among alternative evolutionary scenarios to explain the observed data. All results are integrated over a sample of phylogenetic trees to account for phylogenetic uncertainty. We implement the method in a program called RJ Discrete and illustrate it by analyzing the question of whether mating system and advertisement of estrus by females have coevolved in the Old World monkeys and great apes.
