O Performance Prism como Ferramenta de Controlo de Gestão
Reis, VanessaO controlo de gestão tem um papel fulcral no que concerne a potencializar o desempenho organizacional, quer seja pelo controlo de custos, por servir de apoio à tomada de decisão ou mesmo pelo facto de alinhar os objetivos pessoais dos colaboradores com os objetivos estratégicos da organização. Para que estes objetivos sejam concretizados é essencial a existência de modelos de avaliação de desempenho que permita...
Effects of spatial and seasonal factors on the characteristics and carbonyl ind...
Prata, Joana C.; Reis, Vanessa; Paço, Ana; Martins, Patrícia; Cruz, Ana; Costa, João P. da; Duarte, Armando C.; Rocha-Santos, TeresaCoastal environments are highly contaminated with plastics of various sizes. In order to understand the distribution and factors influencing (micro)plastics contamination in the environment, sampling of a sandy beach in Costa Nova, Aveiro, Portugal, was conducted by collecting plastic particles and sediments for density separation in transects from the mean low tide line to the dunes, during wet and dry seasons...
A new approach for routine quantification of microplastics using Nile Red and a...
Prata, Joana C.; Reis, Vanessa; Matos, João T. V.; da Costa, João P.; Duarte, Armando C.; Rocha-Santos, TeresaMicroplastics are widespread contaminants in the environment. However, most identification protocols rely on long and subjective visual counting, which could be improved using staining dyes. Thus, the objective of this work is to identify the best staining dye protocol and create an objective and quick automated counting software for microplastics. Tests were conducted to identify the most appropriate of eight ...
Functional resilience of PSII, vertical distribution and ecosystem-level estima...
Frankenbach, Silja; Azevedo, Andreina A.; Reis, Vanessa; Dias, Diana; Vaz, Leandro; Dias, João M.; Serôdio, JoãoMost studies on sediment-inhabiting microphytobenthos are based on the biomass present on the surface layers of intertidal flats. However, large amounts of microalgal biomass are known to exist below the surface. This study tested the role of subsurface microalgal biomass as a potential source of photosynthetically active cells for the biofilm on the surface. The resilience of buried cells was evaluated by expo...
Micro(nano)plastics – analytical challenges towards risk evaluation
Pinto da Costa, João; Reis, Vanessa; Paço, Ana; Costa, Mónica; Duarte, Armando C.; Rocha-Santos, TeresaThe quantification of micro- and nanoplastics in environmental matrices is an analytical challenge and pushes to the use of unrealistic high exposure concentrations in laboratory studies which can lead to manifestations of ecotoxicological effects and risks estimation that are transient under natural conditions. Moreover, in field studies, it is difficult to compare the data obtained due to the lack of sampling...
A borboleta monarca (Danaus plexippus) em Odemira - Portugal
Viana, Cláudia; Campos, Rúben; Viegas, Fábio; Silva, Francisco; Graça, Ricardo; Reis, Vanessa; Guerreiro, Madalena; Canha, PaulaA borboleta monarca (Danaus plexippus), nativa do Continente Americano, é famosa pelas suas migrações extraordinárias em extensão e número de indivíduos. Até há pouco tempo foi considerada migrante de passagem no nosso país até se descobrir uma colónia residente em Portugal em Vila Nova de Milfontes. Durante um ano monitorizou-se uma população de borboletas monarca e aplicaram-se diferentes métodos de amostrage...
