The change in the use and exploit of common lands through three generations
Cabo, Paula; Matos, Alda; Ribeiro, Maria Isabel; Fernandes, AntónioThe common lands have a significant potential for sustainable rural development, which would be enhanced by new organizational and operational dynamics of the management bodies, determining factor for the diversification of economic and social activities, and consequent humanization of these lands (CMM, 2015; Rodrigues, 1999; Simões & Cristóvão, 2012; Bica, 2010). The present work describes a paradigmatic case ...

Teixeira, Carlos; Almeida, FilomenaO poster tem por objectivo apresentar o resultado de um projecto que emergiu, numa sala de um Jardim-de-infância da rede pública, a partir da leitura da história Os ovos misteriosos de Luísa Ducla Soares / Manuela Bacelar. O uso de pictogramas no âmbito da literatura de potencial recepção infantil (Azevedo, 2006: 12) tem-se generalizado. A escrita pictográfica de narrativas está mesmo a ser um recurso utilizado...
Desafios da implementação da nova gestão pública
Maia, Tânia; Correia, Pedro Miguel Alves RibeiroA Administração Pública nasceu, evolui e modificou-se em articulação com os sistemas democráticos vigentes, as pressões económicas e os anseios e necessidades dos seus cidadãos. O modelo gestionário surge em 1970-1975, associado ao Estado Neoliberal ou Contratualista. Sobre o que é a Nova Gestão Pública, não existe, nem se imagina que possa existir, uma conceção suficientemente abrangente e aceite por todos os ...

Disponibilidade de azoto e fósforo no solo em olival sujeito a diferentes siste...
Arrobas, Margarida; Claro, Ana Marília; Ferreira, Isabel Q.; Rodrigues, M.A.Diferentes sistemas de gestão do solo afetam significativamente a produção do olival de sequeiro. A aplicação de herbicidas não seletivos pós-emergência no início da Primavera é a estratégia mais efetiva no incremento da produção comparativamente com sistemas que preveem a mobilização do solo ou a gestão da vegetação com corte mecânico ou pastoreio. O efeito benéfico dos herbicidas pós-emergência parece ser dev...
Determination of (0,2)-regular sets in graphs
Pacheco, Maria F.; Cardoso, Domingos M.; Luz, Carlos J.An eigenvalue of a graph is main iff its associated eigenspace is not orthogonal to the all-one vector j. The main characteristic polynomial of a graph G with p main distinct eigenvalues is _ (λ)=λ^−_0 λ^(−1)−_1 λ^(−2)-…-_(−2) λ−_(−1) and it has integer coefficients. If G has n vertices, the nxk walk matrix of G is _=(j,_j,_^"2" "j",…,_^(−) j) and W, the walk matrix of G, is _ for which rank(_)=k. The number k ...
