Evolução da institucionalização de políticas de segurança de sistemas de informação na administração pública portuguesa

As administrações públicas manipulam cada vez mais, grandes quantidades de informação em suportes tecnológicos, por isso são imprescindíveis controlos de segurança cada vez mais rigorosos e abrangentes. De entre as medidas de segurança, as políticas assumem na literatura um papel central. Todavia, um estudo de 2010 aponta a existência de um reduzido número de Câmaras Municipais que têm implementadas políticas de segurança de sistemas de informação [1]. Este artigo contribui para comparar os dados desse estudo com dados de 2016 através da apresentação dos resultados de um inquérito feito à Administração Pública Local em Portugal. Os resultados são discutidos à luz da literatura e identificam-se trabalhos futuros com vista a potenciar a adoção de políticas de segurança na Administração Pública.

Pattern and function of woody features on the grazing itineraries of Terra Fria, Trás–os–Montes – Portugal

The trees, hedgerows and woods are current configuration of the tree network in several ecological regions of the world. In Trás–os–Montes region, Northeast of Portugal, they are a traditional component of Terra fria landscape and they could be seen in several forms: scatter trees, fencerows, small woodlots, riparian buffer strips, among others. The extensive livestock systems in this region are based on a set of circuits across the landscape. In this practice, flocks interacts with these structures using them for different functions inducing an influence on the itineraries. Our purpose will be focused on the woody features of landscape regarding their configurations, abundance and spacial distribution; in order to examine how the grazing systems depends on the currency of these formations; particularly how species flocks behaviors are related on. Depending on spatial data, The investigation attain to compare the tree network within the agriculture matrix, to the grazed territory crossed by flocks. From the other side, the importance of spatial data on interpreting the issue by suggesting different parameter that may influence the circuits. The recognition of the pressure exerciced by the occurence of the woody structures on the grazed circuits is possible. We believe that the role of these woody structures features in supporting the tradicional silvopastoral systems has been sufficiently strong for change their distribution pattern.

Microbiological and physicochemical aspects of “salpicão”, a traditional dry sausage produced in the northeast of Portugal

Counts of total viable mesophilic bacteria (TVC), lactic acid bacteria (LAB), Microccocaceae, Enterobacteriaceae, Salmonella spp. and Listeria monocytogenes, in traditional Portuguese dry sausages from two industrial producers, were compared in batter and final product. During the production process, the TVC increased significantly, most likely due to the multiplication of fermentative flora. Enterobacteriaceae decreased from batter to final product while the S. aureus increased. Great variability was verified in detection of L. monocytogenes both between batches and industrial producers
