How can cyberhate victimization and perpetration be understood?: Towards a psyc...
Vale, Maria; Matos, MarleneThe freedom of expression enabled through information and communication technologies (ICT) has been misused to create, (re)produce, and distribute cyberhate. Otherwise known as online hate speech, it refers to all forms of ICT-mediated expression that incites, justifies, or propagates hatred or violence against specific individuals or groups based on their gender, race, ethnicity, religion, sexual orientation, ...
Cyber-harassment victimization of Portuguese adolescents: a lifestyle-routine a...
Vale, Maria; Pereira, Filipa; Spitzberg, Brian H.; Matos, MarleneCyber-harassment refers to a pattern of repeated, intentional, and unwanted annoyances, impositions, threats, or other aggravating actions mediated by Information and Communication Technologies. Globally, substantial proportions of adolescents experience cyber-harassment, resulting in a host of deleterious health-related consequences. This study tested the empirical utility of the Lifestyle-Routine Activities T...
The effects of land use and land cover geoinformation raster generalization in ...
Meneses, Bruno; Reis, Eusébio; Reis, Rui; Vale, MariaMultiple land use and land cover (LUC) datasets are available for the analysis of LUC changes (LUCC) in distinct territories. Sometimes, different LUCC results are produced to characterize these changes for the same territory and the same period. These differences reflect: (1) The different properties of LUC geoinformation (GI) used in the LUCC assessment, and (2) different criteria used for vector-to-raster co...
Understanding driving forces and implications associated with the land use and ...
Meneses, Bruno; Reis, Eusébio; Pereira, Susana; Vale, Maria; Reis, RuiUnderstanding the processes of land use and land cover changes (LUCC) and the associated driving forces is important for achieving sustainable development. This paper presents the LUCC in Portugal at the regional level (NUTS II) from 1995 to 2010 and discusses the main driving forces and implications associated with these LUCC. The main objectives of this work are: (a) to quantify the land use and land cover (L...

Modeling the probability of surface artificialization in Zêzere watershed (Port...
Meneses, Bruno; Reis, Eusébio; Vale, Maria; Reis, RuiThe land use and land cover (LUC) of the Zêzere watershed (Portugal) have undergone major changes in recent decades, with the increase of artificial surfaces. This trend is quantified in some studies, but the probability of the increase of this type of LUC, nor the places where the next transitions or land use/cover changes (LUCC) for artificial surfaces will have high probability of occurrence has not yet been...
Evidence of long-term changes in the distribution of key intertidal species
Vale, Maria; Neto, Ana I.; Martins, Gustavo M.; Hawkins, Stephen J.Globally, changes are occurring in the biogeochemistry and ecology of the oceans, which may influence the physiology, phenology, and species distribution. Biological communities are reacting to climate change through changes in the abundance and phenology of the organisms and through the poleward shift in species distribution. Rocky shores are relatively simple ecosystems, which makes them an excellent model sy...
Temporal variation in reproductive phenology of Patella spp.: past and present.
Vale, Maria; Ribeiro, Pedro; Golbold, J.; Neto, Ana I.; Martins, Gustavo M.; Hawkins, Stephen J.Global changes occurring in the biogeochemistry o f the oceans may influence the ecology of the biota. There is evidence that species are reacting to changes in climate through variations in the abundance and phenology with many species showing a poleward shift in their distributional range. The rocky intertidal is a relatively simple ecosystem but highly susceptible to anthropogenic activities and is thus an e...
