Percepção Ambiental em Museus Paisagens de Arte Contemporânea: a legibilidade dos museus Inhotim/Brasil e em Serralves/Portugal avaliada pelo público/visitante

This thesis nalyzes the wayfinding in Landscape Museum of Contemporary Art (MPAC), based on the Institute of Contemporary Art CACI, Minas Gerais, Brazil and the Museum of Contemporary Art of the Serralves Foundation, Porto, Portugal. The study focuses on the interrelationship of the public/visitors with the landscape, architecture and contemporary art museums in these, in order to understand visual perception and apprehension of such an environment for their users. For both were confronted documentation (visual and written) and people talk. The main hypothesis put forward is that the audience/visitor MPAC appreciates the interrelationship between the natural environment (park/garden) and built environment (the works of contemporary art and the galleries), giving equal value to both. To complement this, a second hypothesis is that during the visit to MPACS, visitors define their paths spontaneously, but strongly influenced by existing visual indicators (maps, signage and striking landscape elements), which facilitate the readability of space, which also contribute to the offered services and the experiences of similar institutions. The analytical basis of the research used the concepts of legibility (LYNCH, 2009), wayfinding (GIBSON, 2009; ARTHUR, PASSINI, 2002; WEISMAN, 1982), Experiential Cotinnum (TUAN, 1985), Space Bound (CRUZ PINTO, 2007) and habitus (BOURDIEU, 1992). Methodologically was used qualitative research (DEMO 2000) by means of a case study (YIN, 2005; STAKE, 1999) and participant observation (WHYTE, 2005). In the two institutions interviews with researchers and curators, behavior observation and questionnaires from employees, trainees, monitors and the public/visitor of the two museums were performed. Although partially referende the initial hypothesis, the research showed that the public/visitor value appears more natural environments, they experience a greater intensity and in addition to the factors listed in the second case, your perception and definition of paths suffer significant influence of emotional relations established with space. Generally the audience/visitor adapts easily to different demands of contemporary art exhibition in the two museums and the built environment (park/garden and museum) interferes with your reading path during the visit, perceived by the public/visitor condition as a factor that favors the enjoyment of works on different mounts (wayfinding), though often become a factor that hinders the legibility of the building and its built environment

Análise de sobrevivência ao cancro colo-retal nos períodos 2000-2001 e 2007-2008 na região norte de Portugal

O cancro colo-retal é um dos tipos de cancro mais comuns, em ambos os sexos, tendo em conta os dados existentes nos registos oncológicos nas mais diversas regiões do globo, facto que acontece também na região Norte de Portugal. O objetivo desta dissertação foi utilizar métodos de análise de sobrevivência tradicional e de análise de sobrevivência relativa, em dados do cancro colo-retal, considerando um período de observação de 5 anos. Os dados analisados são provenientes do Registo Oncológico Regional do Norte (RORENO), obtendo-se, após inspeção e tratamento prévio, um total de 2855 pacientes aos quais foi diagnosticado cancro colo-retal em dois períodos distintos, 2000-2001 e 2007- 2008. Pretendeu-se também determinar de que forma as covariáveis influenciam a sobrevivência, e como esta evoluiu entre essas duas coortes. Dado não existir informação sobre as causas de morte, foi objetivo deste estudo estimar que parte da mortalidade observada se deve à doença em questão e que parte se deve a outras causas que afetam a mortalidade da população geral. Foram, também, estimados os coeficientes das covariáveis consideradas para os modelos adotados. Todos os resultados foram obtidos utilizando como recurso o software R e seus pacotes adequados. Utilizaram-se diversos métodos tais como Kaplan-Meier, Cox, Ederer II e Net Survival, sendo este último considerado o mais adequado a este tipo de estudo pois é considerado pela comunidade científica o único estimador centrado para análise de sobrevivência relativa e cujas propriedades estatísticas permitem a sua utilização em estudos comparativos entre países. Verificou-se, por este estimador, que não existem diferenças significativas na sobrevivência em função do sexo, idade, distrito ou localização do cancro (cólon ou reto). Por outro lado verificaram-se diferenças significativas para a sobrevivência em função do estadio e das coortes, registando-se um acréscimo global de 8.5% na sobrevivência aos 5 anos de 2000-2001 para 2007-2008. Por fim destacam-se alguns aspetos que merecem atenção em estudos futuros.

An overview of the submerged sea caves of Sagres (South of Portugal-Algarve)

The submerged sea caves of Sagres are located within the “Parque Natural do Sudoeste Alentejano e Costa Vicentina (PNSACV)” Marine Protected Area (MPA). This MPA integrates the national network of protected areas, addressed by the National Institute for Nature Conservation and Forest (ICNF) and was declared Site of Community Importance (SCI) under the Habitats Directive. Under the Annex I from the Habitat Directive these habitat caves are included in “8330 Submerged or partially submerged sea caves”. This conservation status should provide sufficient concern to have detailed information on biodiversity. However, among marine researcher, little is still known about these submerged sea caves and tunnels habitats. The only well-known study dealing with the Sagres sea caves was conducted in the late 80s and was only published in 2001. For effective management of such specific habitats a clear understanding of their localization and extension, the assessment of the biological communities, its conservation importance, its monitoring options and their sensitivity to natural change and human disturbance need to be a relatively clear. This report, produced under the MeshAtlantic Project, provides an overview of the available published and unpublished information relevant for the conservation management of the subtidal caves of Sagres. It mainly aims to be a base contribution for future studies.

Gender and size diversity in top management team: evidence from Portugal

In recent years the Top Management Team (TMT) in the companies has been extensively studied and discussed by many researchers (Campbell & Mínguez-Vera, 2008; Erhardt et al, 2003; Haleblian & Finkelstein, 1993; Amason & Spienza, 1997). Thus, this theme has undergone a major evolution as well as it has been diversified progressively. Combined with the Upper Echelons Theory, it was established a new dimension of diversity of the Top Management Team that addresses, for example, the diversity of gender and the size of the team. There are several countries that have established laws and regulatory requirements in order to increase the presence of women in the business environment such as Norway, Spain, France, Holland and Italy. However, the female gender is far from equal in terms of representativeness (Torchia et al., 2011), but there are noteworthy developments yearly. It is also noticeable that the size of Top Management Teams has also increased, which can provide advantages for the company (Heleblian & Finkelstein, 1993). In the course of this dissertation it was studied the female gender ratio and the size of the Top Management Team with the profitability (ROA – Return On Assets) of 41 Portuguese companies listed on the Euronext Lisbon between 2011 - 2015. Initially, the Spearman test was applied in order to verify the correlations between the variables in study. It was created a linear regression that relates the number of women (independent variable) and ROA (dependent variable). The Mann-Whitney test was used to verify the ROA behaviour between companies with no women in TMT and companies with women in TMT. After analysis, the results demonstrated that there was a positive relationship between the number of women with ROA. Also companies that have women in TMT have better performance compared to companies with no women in the Top Management Team. As far as the size of the team is concerned, it positively influences the economic profitability, in a meaningful way.

Fusões e aquisições no setor bancário em Portugal: análise do caso Millennium BCP e Banco BPI

Muitas referências apontam para as Fusões e Aquisições (F&A) como um dos meios mais privilegiados pelas instituições de crédito para fortalecerem a sua posição competitiva. As análises realizadas até hoje debruçam-se essencialmente sobre a observação das motivações, oportunidades e consequências das F&A, das suas vantagens e desvantagens, bem como encontrar a evidência que favoreça a ligação entre concentração e poder de mercado. O principal objetivo deste trabalho passa por inicialmente contribuir através de uma revisão literária existente, para um conhecimento mais abrangente das causa e efeitos dos processos de F&A, com o enfoque no conhecimento bancário. Esta análise é complementada, numa vertente mais empírica, pela avaliação de uma operação de fusão o Millennium BCP e Banco BPI, seguida de uma análise dos possíveis ganhos e a sua repartição pelas entidades envolvidas e respetivos investidores, das sinergias criadas bem como da forma de pagamento. A metodologia baseia-se nos dois primeiros capítulos, em pesquisa bibliográfica sob a forma de revisão de literatura. No terceiro capítulo, para estimar o valor das empresas, utiliza-se o método de análise dos Fluxos de Caixa Atualizados – nas projeções do cash-flow e no valor residual estimado. É feito um reforço desta avaliação através do Método dos Múltiplos. Por fim, é feita uma breve conclusão em modo discussão, onde são evidenciados os principais efeitos ocorridos com a proposta de fusão, tanto no que respeita as entidades financeiras envolvidas, como os acionistas e os seus gestores. Esta mesma conclusão permite verificar que a fusão seria um caminho estratégico viável para as instituições de crédito envolvidas e acionistas.

Literacia em saúde, dos dados à ação: tradução, validação e aplicação do European Health Literacy Survey em Portugal

Nos últimos anos, diferentes estudos têm demonstrado que um nível inadequado de literacia em saúde pode ter implicac¸ões significativas nos resultados em saúde, na utilizac¸ão dos servic¸os de saúde e, consequentemente, nos gastos em saúde. O conceito de literacia em saúde evoluiu de uma definic¸ão meramente cognitiva para uma definic¸ão que engloba as componentes pessoal e social do indivíduo, assumindo-se como a capacidade de tomar decisões fundamentadas no seu dia-a-dia. O presente estudo transversal analítico teve como objetivo traduzir e validar para a populac¸ão portuguesa o European Health Literacy Survey (HLS-EU). O HLS-EU-PT foi aplicado em todo o território nacional, incluindo as regiões autónomas, através de investigadores de uma rede académica. A recolha de dados foi realizada por entrevista presencial. A amostra final ficou constituída por 1.004 indivíduos com idades ≥ 16 anos. Este estudo disponibilizou o instrumento de avaliac¸ão do nível de literacia para a saúde em Portugal, tão importante na gestão da saúde. O HLS-EU-PT apresenta-se como um instrumento adequado para aferir o nível de literacia em saúde da populac¸ão portuguesa e evidencia propriedades psicométricas comparáveis às versões utilizadas nos outros países. Em Portugal, 61% da populac¸ão inquirida apresenta um nível de literacia geral em saúde problemático ou inadequado, situando-se a média dos 9 países em 49,2%. Relativamente à dimensão cuidados de saúde, apenas 44,2% apresenta um nível suficiente ou excelente de literacia em saúde. No que respeita à prevenc¸ão da doenc¸a, cerca de 45% dos inquiridos revela ter um nível suficiente ou excelente de literacia em saúde, comparativamente com a média dos 9 países, que nesta dimensão apresenta o valor de 54,5%. Na dimensão promoc¸ão da saúde, 60,2% da populac¸ão auscultada apresenta um nível de literacia em saúde problemático ou inadequado, sendo que a média se situa nos 52,1%. Assim, considera-se fundamental e urgente a conceção e implementação de uma estratégia nacional de literacia em saúde.

A relação entre a preocupação com a saúde e imagem e o consumo de produtos dietéticos/light: um caso de estudo em Portugal

O comportamento humano tem sofrido mudanças significativas nos últimos anos, motivadas por um maior nível de consciência dos consumidores para problemas de saúde com génese em hábitos alimentares deficientes, muito devido á diminuição do analfabetismo e a maior acesso à informação. Optando por hábitos alimentares saudáveis, o consumidor não abdica das características organoléticas que mais aprecia. Os produtos alimentares diet e light, antes de serem considerados alimentos para obviar as doenças do foro alimentício, são-no para manter e promover um corpo mais saudável. Um estudo empírico, realizado em Portugal, conclui pela identificação de uma relação positiva entre o consumo de produtos dietéticos /light e a imagem física e a manutenção de níveis de saúde associados a uma vida com maior qualidade. Infere-se, adicionalmente, uma clara propensão da população para uma procura crescente a ser suprida com a réplica da pastelaria tradicional, mas elaborada com substâncias dietéticas e light.

Catches of the sport fishing competitions along the Algarve coast (Portugal): species, sizes, catch rates, and trends

Background. Stocks of many marine fishes are in decline and a number of studies suggest that for some species the impact of recreational angling may be important. To date, only recreational (leisure) fishing surveys have been conducted in Portugal, with no studies on beach angling competitions, dynamically increasing in number over the past 10 to 20 years. In view of the above, we decided to evaluate the impact of such events on the Algarve coast (southern Portugal) in terms of the abundance, diversity, and respective weight of fish species caught and outline some conservation measures and recommendations for the management of the targeted species. Materials and methods. Participants of 22 angling competitions taking place between February and June 2007 were surveyed. In each competition a random sample of anglers was interviewed, and the specimens caught by each participant were identified, weighed, and measured. Results. Thirteen taxa belonging to eight families were identified, and the most common were: garfish, Belone belone (Linnaeus, 1761); mullets, Mugilidae (not identified); and mackerels, Scomber spp. A total of 563 specimens were sampled, totalling 75.4 kg of weight, with the average catch per angler weighing 0.5 +/- 0.05 SE (n = 153) kg. Differences were also observed between the length at first maturity (L(50)) of the specimens caught and their respective Minimum Landing Size (MLS) and Allowed Minimum Size (AMS), most particularly in the case of the European seabass, Dicentrarchus labrax (L.), with almost all individuals caught measuring below the species-specific L50. Analysis of time series of competition results (1996-2009) showed no evidence of a decrease in catches or in mean weight. Conclusion. Based on the results we propose that the AMS for beach angling competitions should be increased to the MLS in order to prevent the capture of juvenile fishes, especially the sea bass. Future studies should address the size selectivity of the hooks used in beach competitions, with a view to the implementation of a minimum hook size for competitions.

First record of Calcinus tubularis on the southern coast of Portugal (Crustacea: Decapoda: Anomura: Diogenidae)

Twenty-five specimens of the hermit crab Calcinus tubularis were observed during SCUBA dives for fauna and flora assessment in the shallow rocky reefs of the southern coast of Portugal between 2003 and 2008. Of the specimens observed, only one specimen used a tube gallery, while the others occupied unidentified gastropod shells with strong bio-cover. Calcinus tubularis is here recorded from the mainland Portuguese coast for the first time. This is the first record of the species in European coastal waters outside the Mediterranean Sea (excluding the Atlantic Islands) and extends the known geographical distribution of the species further north in the north-eastern Atlantic.

Spatial and depth-associated distribution patterns of shallow gorgonians in the Algarve coast (Portugal, NE Atlantic)

The ecological role of gorgonians for marine rocky bottoms is worldwide recognized, but the information on the distribution patterns of NE Atlantic temperate species is insufficient, considering current global, regional and local threats. To overcome the lack of information on the spatial distribution patterns of gorgonians in south Portugal, in 2009/2010, the occurrence and abundance of gorgonian species in rocky bottoms were quantified over more than 25 km of coast (37.1N/8.6W) down to 30 m depth. Eunicella labiata, Eunicella gazella, Eunicella verrucosa and Leptogorgia sarmentosa were abundant and frequent in the studied area, while Leptogorgia lusitanica was less abundant. All species evidenced a similar depth pattern, that is abundance significantly increased with depth below 15 m. At shallower waters (up to 15 m), the distribution of gorgonians may be constrained by abiotic factors and competition with algae. Indeed, the abundance of gorgonians was negatively correlated with the percentage cover of algae along the depth gradient, but gorgonians and sponges coexist. Competition among gorgonian species also seems to be low in this area because of the similarity in the abundance pattern observed for the most abundant species and also their high association. In NE Atlantic shallow temperate rocky bottoms, the distribution of gorgonians seems to be influenced by environmental factors and biological interactions, namely competition (algae) and coexistence (sponges and other gorgonians).

Marine litter in the upper São Vicente submarine canyon (SW Portugal): abundance, distribution, composition and fauna interactions

Marine litter has become a worldwide environmental problem, tainting all ocean habitats. The abundance, distribution and composition of litter and its interactions with fauna were evaluated in the upper S. Vicente canyon using video images from 3 remote operated vehicle exploratory dives. Litter was present in all dives and the abundance was as high as 3.31 items100m(-1). Mean abundance of litter over rock bottom was higher than on soft substrate. Mean litter abundance was slightly higher than reported for other canyons on the Portuguese margin, but lower in comparison to more urbanized coastal areas of the world. Lost fishing gear was the prevalent type of litter, indicating that the majority of litter originates from maritime sources, mainly fishing activity. Physical contact with sessile fauna and entanglement of specimens were the major impacts of lost fishing gear. Based on the importance of this region for the local fishermen, litter abundance is expected to increase.

Semi-pelagic Longline and Trammel Net Elasmobranch Catches in Southern Portugal: Catch Composition, Catch Rates and Discards

In Portugal, elasmobranch landings have decreased substantially in recent years. In this work, elasmobranch catches in semi-pelagic longlines (1997 and 1998) were compared with those in trammel nets (2000) in the Algarve, southern Portugal areas. In the semi-pelagic longline fi shery, 7 elasmobranch species represented 33.4% (2 185 specimens) of the total fi sh catches. Among the elasmobranch species, the most abundant were Galeus melastomus (63.3%), Etmopterus pusillus (21.7%) and Scyliorhinus canicula (14.2%). Most of these elasmobranchs were discarded (68.3% in total). In the trammel net fi shery, 16 different elasmobranch species represented 4.3% (597 specimens) of total fi sh catches and the most important species were Raja undulata (43.6%) and S. canicula (10.2%). The majority of the elasmobranchs caught in trammel nets had commercial value, and only 5.4% were discarded. In both fi sheries, intra-specifi c catch rates varied with depth. Length-frequency distributions for the only species with relatively high catches in both fi sheries, S. canicula, showed that, in general, trammel nets catch larger specimens and in a narrower length range than do longlines.

Fate of discards from deep water crustacean trawl fishery off the south coast of Portugal

Trawling for crustaceans takes place on the south coast of Portugal at depths between 200 and 800 m. Large amounts of discards are released back to sea, reaching the bottom in the general area where trawling occurs. The objective of this work was to study the time taken for decomposition of the discards, to identify the most important scavenging species involved, and to evaluate the impact on the species targeted by the fishery. We conducted a series of 22 trials, using traps baited with samples of the discards. The time of immersion varied between 1 and 40 h. The amount of tissue removed from the discards was evaluated on a qualitative scale of 1–3, and quantitatively. The species caught in the traps were identified. Considerable consumption of the bait had occurred after 5 h of immersion. After 24 h of immersion only fish bones were left; past 40 h, consumption was complete. The conger eel (Conger conger) was the most common fish species present in the traps. Two species, the amphipod Scopelocheirus hopei and the isopod Natatolana (Cirolana) borealis, were identified as most important for the recycling of organic matter in the system. The stomach contents of a sample of species caught in trawls were analysed for the presence of small scavengers. Preliminary results show that S. hopei and N. (C.) borealis are part of the diet of some of the target species of this fishery, such as the Norway lobster, Nephrops norvegicus and the rose shrimp Parapenaeus longirostris.

Age, growth and reproduction of the Axilary Seabream, "Pagellus acarne" (Risso, 1827), from the South coast of Portugal

Axillary seabream, Pagellus acarne, caught by longlines in the Algarve (Southern Portugal), were sampled between August 1995 and August 1996. Age was studied by counting growth increments on otoliths and the estimated von Bertalanffy parameters were Linf = 28.82 cm, K = 0.29 year-1 and t0 = -1.47 year for males and Linf = 32.30 cm, K = 0.18 year-1 and t0 = -2.56 year for females. Evidence of the annual periodicity of the deposition of increments was found by marginal increment analyses. Macroscopic analysis of the gonads and the gonad somatic index showed that reproduction occurred over an extensive period of time, from May to November. Lengths at first maturity were 18.10 and 17.60 cm for males and females, respectively. This species was characterized as being a protandric hermaphrodite.
