Le design expérientiel dans l'espace marchand

Issu de la rencontre entre les disciplines de l’architecture intérieure et de la stratégie de marque et développé en réponse au raffinement de l’offre et des nouveaux modes de consommation, le design expérientiel présente un champ de pratique émergent qui tend vers la communication d’une expérience client marquante et immersive à travers l’environnement commercial. Bien que le sujet soit richement documenté par le domaine du marketing, il est apparu qu’il l’est moins par celui de l’aménagement. En effet, peu d’études démontrent concrètement la façon d’aménager l’espace marchand dans le contexte de la pratique du design expérientiel ou cherchent à mettre en lumière son empreinte physique sur l’environnement commercial. Cette recherche vise simultanément l’amélioration de la compréhension de la pratique émergente qu’est le design expérientiel ainsi que l’identification des caractéristiques environnementales propres aux espaces marchands qui en découlent. Dans la volonté de sonder le phénomène du design expérientiel tant dans la dimension conceptuelle de sa pratique que dans celle de son résultat bâti, la stratégie méthodologique de cette recherche repose sur la tenue d’entretiens semi-dirigés avec des professionnels basant leur pratique sur le design expérientiel et l’observation directe de trois projets commerciaux expérientiels reconnus. L’issue de cette recherche et les résultats extraits du terrain mèneront plutôt à relever l’existence d’un processus de conception caractéristique à la pratique ainsi que celle de concepts fondateurs qu’à identifier des éléments de l’aménagement intérieur propres aux environnements commerciaux en découlant. Nettement apparus au cours de l’étude, ce processus et la volonté de mettre sur pied une stratégie de communication solide semblent occuper une place plus importante dans la définition et la compréhension de la pratique du design expérientiel que les attributs de l’espace marchand comme tel.

A emergência da governança socioambiental no mercado internacional de biocombustíveis

O esgotamento das reservas de energia fóssil e o processo de mudanças climáticas causadas pelas emissões de GEEs posicionaram os biocombustíveis como a principal fonte alternativa de energia renovável disponível para uso em transportes no curto e médio prazos. Contudo, a presença de externalidades e assimetrias de informação dificultam a verificação da sustentabilidade neste setor. Assim, a emergência do mercado internacional de biocombustíveis mostra-se condicionada pela construção de instituições que garantam a sustentabilidade da produção e consumo desses produtos. O processo de construção das instituições de governança socioambiental é afetado por fatores de ordem técnica, política e institucional. Apoiado em aportes teóricos do institucionalismo econômico e sociológico, o presente estudo buscou analisar que elementos afetam este processo considerando a trajetória de mercados já estabelecidos que apresentam caraterísticas análogas ao setor de biocombustíveis (alimentos orgânicos e produtos florestais). A forma como legislações nacionais, acordos internacionais e sistemas de certificação privada se desenvolveram e interagiram nesses setores apresenta aderência com o processo de construção do mercado de biocombustíveis observado até o momento. Dentre os resultados encontrados, observa-se tendência à convergência entre padrões de sustentabilidade em diferentes legislações nacionais e sistemas de certificação privados devido às externalidades de rede que conferem maior valor a padrões adotados por uma gama mais ampla de usuários. A União Europeia desponta como o principal formador de padrões de sustentabilidade, dado seu perfil importador e o estabelecimento de critérios mais amplos nas legislações dos Estados Membros, geralmente implementada via integração de mecanismos de governança públicos e privados (meta-standards). Apesar do expressivo potencial de consumo, os EUA apresentam menor influência nesse processo devido a considerável capacidade de produção doméstica e a priorização de elementos estratégicos (segurança energética e desenvolvimento rural) no desenho de suas políticas de sustentabilidade para combustíveis de biomassa. Na esfera privada, o desenvolvimento de sistemas de certificação apresenta-se condicionado por elementos técnicos, como a eficiência em cobrir critérios relevantes e os custos incorridos neste processo; e políticos, relacionados à capacidade de legitimição dos atores envolvidos em cada um destes programas de certificação. Também se observa que caraterísticas tecnológicas e organizacionais das cadeias de produção de biocombustíveis afetam a expansão de sistemas de certificação, condicionando tanto os custos para o estabelecimento da cadeia de custódia como a capacidade de coordenação de ações setoriais visando a adoção de práticas sustentáveis que facilitem a obtenção da certificação. Essa relação fica evidente em novas nações que buscam estabelecer um setor bioenergético e enfrentam dificuldades em integrar a agricultura familiar à modelos de produção que respeitem critérios socioambientais vigentes no mercado internacional. A pesquisa revelou a necessidade de um entendimento mais aprofundado da interconexão de novas rotas tecnológicas e atores adentrando no mercado internacional de biocombustíveis. A compreensão dos riscos e potencialidades de novas formas de interação pública e privada na governança socioambiental apresenta-se como um campo prolífico para futuros estudos neste setor e em outros em que atributos ambientais se mostrem relevantes.

Percepção dos usuários nos espaços públicos: avaliação pós-ocupação em três praças de Natal-RN

The research investigates the acting and the importance for the users of the public squares located predominantly in residential areas. It presents the results of the posoccupation evaluations accomplished in three squares, whose physical, environmental characteristics, equipments and fumitures are different in its qualities and amounts, taking in consideration aspects related to the users' physical and psychological comfort and of the inhabitants of the I spill. The collection of data involved physical risings and of files, observations behavious, application of questionnaires and interviews, analyzed qualitative as quantitatively so much for a larger precision and validity of the investigation. The results were obtained through the relationship among the users' perception the environmental attributes and the different levels of apropriation/use of the studied places. They indicate that the aspects composicionais of physical order of the space affects the type and the intensity of use of the squares intimately, contributing positive or negatively for its valor. It is evidenced like this, that the low freqüentation of the public squares of Natal, is due mainly to referring aspects to the physical quality and the amount of the fumitures and urban equipments. It is ended that the investments and the physical planning of these public spaces should be based in the real knowledge of the aspirations of the population objective, in way to allow its largest use and valor

Distribution of paracoccidioidomycosis: determination of ecologic correlates through spatial analyses

Paracoccidioidomycosis (PCM) is endemic in Latin America and in countries like Brazil it carries a high mortality rate. The fungus' habitat has not been precisely determined. The present study aims to identify ecologic correlates based on PCM distribution in a hyper-endemic area in southeastern Brazil. The Geographic Information System (GIS) and spatial statistics were used to associate environmental attributes, human population density and, PCM distribution. By means of the Pearson r correlation coefficient, the highest statistically significant associations with prevalence density were the percent area (by county) of: basaltic rocks (r = 0.63; P < 0.0001), Podzolic soils (r = - 0.48; P < 0.001), Latosol soils (r = 0.40; P < 0.01), mean annual precipitation between 1500 and 1600 mm (r = 0.46; P < 0.001) and, mean precipitation during the wet season between 940 and 1040 mm (r = - 0.44; P < 0.01). Soil texture and precipitation analyzed together reached r = 0.61 (P < 0.000002) for fine-textured soils with annual precipitation above 1400 mm. Environmental correlates indicate that moisture availability plays an important role in PCM distribution.

Baixa diversidade de zooplâncton na desembocadura de uma represa eutrófica (SP, Brasil): reflexo da poluição?

The Tiete River (in São Paulo state) receives most of the efuents of the metropolitan region of São Paulo; and the Barra Bonita reservoir, 200 km distant downstream, receives and recycle most of that pollution load. This work studied the ecological features of the zooplankton (Rotifera, Cladocera and Copepoda) sampled in a point of Tiete River's mouth. Monthly samples were collected, from April, 2001 to February, 2008. The hypothesis currently tested was that the composition and availability of zooplankton were similar to the others reservoir regions (middle and lacustrine sensu Thornton) and to other reservoirs of the Upper Parana River basin, supporting the idea that these organisms manage to stand the strong pollution. The reservoir shows a typical variation of accumulation, with wide variation of seasonal altimetric grading and large fow in the rainy pe- riod, infuenced by the rainfall regime, with efects upon zooplankton assemblage. As a whole, 24 species were registered: 12 Rotifera, 8 Cladocera and 4 Copepoda. Data showed that the hypothesis formulated must be rejected, due the variation trends of zooplankton environmental attributes not being regular, with relatively high abundance values for a lotic environment in specifc months, and low organism abundance or absence in other months. Those facts can be attributed to pollution efects conducting to low dissolved oxygen concentration (> 4mg.l-1) in some months, which causes the zooplankton community to be very much afected. [K]

The major three chapters of this dissertation contain three subsystems in this work, each corresponding to one subsystem: BioLogger, PAMS and CosNet. Each chapter covers the background and motivation of the subsystem, the related theory, the hardware/software design, and the evaluation of the prototype’s performance.

Adequabilidade ambiental dos biomas brasileiros à ocorrência do lobo-guará (Chrysocyon brachyurus) e efeitos da composição da paisagem em sua ecologia espacial, atividade e movimentação

O lobo-guará é uma espécie de ampla distribuição na América do Sul, tendo no Brasil sua maior área de ocorrência. No entanto, as modificações das áreas naturais principalmente destinadas à agropecuária tornam a espécie vulnerável à extinção. A investigação objetivou conhecer em larga escala a área de distribuição potencial gerada por atributos ambientais favoráveis e áreas adequadas à sua ocorrência nos biomas brasileiros e investigar como a espécie responde à estrutura da paisagem, avaliando os efeitos de ambientes modificados pelo homem na sua ecologia espacial, nos padrões de atividade e na movimentação. Modelos de distribuição de espécie foram gerados pelo Maxent, utilizando uma base de pontos de localização de presença a partir de 2000 para o Cerrado (Ce), Pantanal (Pa), Mata Atlântica (MA) e Pampas (Pp) e um conjunto de onze variáveis ambientais não correlacionadas (topográficas, climáticas e paisagísticas). Para análises de ecologia espacial, das atividades e de movimentação, utilizou-se localizações de telemetria (GPS) de animais habitantes de áreas protegidas (AP), e indivíduos em paisagens modificados (AM). Análises de áreas de vida (AV) foram realizadas utilizando o estimador AKDE e associadas com classificação da paisagem local. Os modelos de distribuição do lobo-guará apresentaram uma área de distribuição potencial de 78% do total dos biomas. Apesar de possuírem grandes proporções de áreas adequadas (Ce, 90%; Pa, 93%; MA, 65% e Pp, 6%), somente um pequeno percentual (4,4% do Ce e 4,7% da MA) possui adequabilidade ambiental acima de 50%. Dos atributos que favorecem sua presença, a altitude (para todos os biomas), a precipitação (Ce e Pa), diferenças de temperatura e uso e cobertura do solo (Ma e Pp) foram os mais importantes. Em nível local, animais apresentaram média de AV de 90Km2 em AP e 41Km2 em AM, uma diferença significativa (p<0,01) com áreas diretamente proporcionais ao percentual de áreas naturais na paisagem. Ainda, apesar dos padrões regulares de atividade não mostrarem grandes mudanças, o período de repouso foi significativamente maior (p<0,01) entre os animais AM (46% do dia) que em animais AP (25% do dia). Lobos-guarás de AP e AM não apresentaram grandes diferenças no deslocamento diário com média geral de 14km caminhados por dia, com comprimentos de passos de 1Km. Diferenças no comprimento de passo foram relacionadas à composição da diversidade de contato de classes da paisagem com a proporção de ambientes naturais no passo (quanto maior as variáveis, maior o passo). Passos menores refletem menor persistência de movimento interferindo no deslocamento diário. Com os resultados desse estudo identificou-se a MA e Pa muito importantes, mas o Ce como bioma mais adequado à espécie. Foram encontrados indícios de que a estrutura de suas AV, o uso da paisagem, as atividades e movimentação são afetados pela paisagem modificada. Isso pode comprometer a viabilidade populacional, interferindo na presença em uma área e refletindo no seu potencial de distribuição. As estratégias de manejo de uso do solo, e a recuperação e conexão de áreas adequadas são urgentes e necessárias para que o lobo-guará permaneça presente e funcional nas paisagens dos biomas brasileiros.

Airport Security: Passenger's Perception and Design Issues

The main goal of this thesis is to report patterns of perceived safety in the context of airport infrastructure, taking the airport of Bologna as reference. Many personal and environmental attributes are investigated to paint the profile of the sensitive passenger and to understand why precise factors of the transit environment are so impactful on the individual. The main analyses are based on a 2014-2015 passengers’ survey, involving almost six thousand of incoming and outgoing passengers. Other reports are used to implement and support the resource. The analysis is carried out by using a combination of Chi-square tests and binary logistic regressions. Findings shows that passengers result to be particularly affected by the perception of airport’s environment (e.g., state and maintenance of facilities, clarity and efficacy of information system, functionality of elevators and escalators), but also by the way how the passenger reaches the airport and the quality of security checks. In relation to such results, several suggestions are provided for the improvement of passenger satisfaction with safety. The attention is then focused on security checkpoints and related operations, described on a theoretical and technical ground. We present an example of how to realize a proper model of the security checks area of Bologna’s airport, with the aim to assess present performances of the system and consequences of potential variations. After a brief introduction to Arena, a widespread simulation software, the existing model is described, pointing out flaws and limitations. Such model is finally updated and changed in order to make it more reliable and more representative of the reality. Different scenarios are tested and results are compared using graphs and tables.

Trial of print and telephone delivered interventions to influence walking

Background. Both self-help print materials and telephone-assisted counseling have generally proved useful strategies to increase physical activity. This study examined their effectiveness in an intervention aimed specifically at promoting walking for specific purposes. Methods. Participants (n = 399) were randomly allocated to one of two 3-week intervention programs. The Print program comprised multiple mailing of brochures that emphasized walking within the local community environments. The Print plus Telephone program received the same brochures plus three telephone calls. Data collected via mailed self-completed surveys were analyzed by exploring outcomes related to walking for specific purposes. Results. There were no significant differences between the two programs in any of the walking measures. Both groups significantly increased time reported walking for exercise per week [Print: t(1,277) = -3.50, P < 0.001; Print plus telephone: t(1,106) = -2.44, P < 0.016]. Significantly, more participants in the Print plus Telephone group reported receiving and reading the materials (chi(2) = 20.11, P < 0.0001). Conclusions. The intervention programs were more successful at increasing walking for exercise than for any other purpose. The addition of brief telephone support was successful in focusing participants' attention on the print materials, but did not result in any additional increase in walking.

Sustainability metrics for coal power generation in Australia

The basis of this work was to investigate the relative environmental impacts of various power generators knowing that all plants are located in totally different environments and that different receptors will experience different impacts. Based on IChemE sustainability metrics paradigm, we calculated potential environmental indicators (P-EI) that represent the environmental burden of masses of potential pollutants discharged into different receiving media. However, a P-EI may not be of significance, as it may not be expressed at all in different conditions, so to try and include some receiver significance we developed a methodology to take into account some specific environmental indicators (S-EI) that refer to the environmental attributes of a specific site. In this context, we acquired site specific environmental data related to the airsheds and water catchment areas in different locations for a limited number of environmental indicators such as human health (carcinogenic) effects, atmospheric acidification, photochemical (ozone) smog and eutrophication. The S-EI results from this particular analysis show that atmospheric acidification has highest impact value while health risks due to fly ash emissions are considered not to be as significant. This is due to the fact that many coal power plants in Australia are located in low population density air sheds. The contribution of coal power plants to photochemical (ozone) smog and eutrophication were not significant. In this study, we have considered emission related data trends to reflect technology performance (e.g., P-EI indicators) while a real sustainability metric can be associated only with the specific environmental conditions of the relevant sites (e.g., S-EI indicators).

Website physical activity interventions: preferences of potential users

Information and communication technologies (particularly websites and e-mail) have the potential to deliver health behavior change programs to large numbers of adults at low cost. Controlled trials using these new media to promote physical activity have produced mixed results. User-centered development methods can assist in understanding the preferences of potential participants for website functions and content, and may lead to more effective programs. Eight focus group discussions were conducted with 40 adults after they had accessed a previously trialed physical activity website. The discussions were audio taped, transcribed and interpreted using a themed analysis method. Four key themes emerged: structure, interactivity, environmental context and content. Preferences were expressed for websites that include simple interactive features, together with information on local community activity opportunities. Particular suggestions included online community notice boards, personalized progress charts, e-mail access to expert advice and access to information on specific local physical activity facilities and services. Website physical activity interventions could usefully include personally relevant interactive and environmentally focused features and services identified through a user-centered development process.
