The biological family from the perspective of kinship fostered adolescents

Background: Previous studies emphasise the importance of the biological family to the welfare of fostered adolescents. However, the majority of these studies only take into consideration the viewpoints of the professionals, foster parents and biological parents not those of the adolescents themselves. For this reason little is known about the perceptions the adolescents have and the needs they express. Method: This study has gathered data from 57 adolescents in kinship family fostering in Spain (AFE). The study applied qualitative reseach, using focus groups to gather data and the Atlas.ti programme to analyse the data. The qualitative data give us a more profound understanding of how the fostered adolescents relate to their biological families. Results: The results highlight the specific needs of these adolescents a) an understanding of their family history b) the impact of visits from and relationship with their biological family and c) the relationship between the biological family and the foster family. Conclusions: These findings reveal implications to consider when creating support programmes aimed at this group.

Las comunidades liquenicas saxicolas ombrofobas de la costa del SE de EspaÑa comprendidas entre el Penyal d'Ifac (Alicante) y Almeria

The ombrophobic saxicolous lichen communities in the coastal SE Spain, between the Penyal d'Ifac (Alicante) and Almeria. The authors describe the calcicolous and silicicolous communities, as observed by them in the coast of SE Spain. They include the whole in a new alliance, Roccellion phycopsis, with two associations characterized by a number of thermophilous Trentepholia -containing species, belonging to order Arthoniales, and neighbouring from taxonomic and ecologic viewpoints. All the studied communities are aerohygrophilous, heliophobic and fairly to scarcely photophilous.

Viewpoint-Based Ambient Occlusion

We've developed a new ambient occlusion technique based on an information-theoretic framework. Essentially, our method computes a weighted visibility from each object polygon to all viewpoints; we then use these visibility values to obtain the information associated with each polygon. So, just as a viewpoint has information about the model's polygons, the polygons gather information on the viewpoints. We therefore have two measures associated with an information channel defined by the set of viewpoints as input and the object's polygons as output, or vice versa. From this polygonal information, we obtain an occlusion map that serves as a classic ambient occlusion technique. Our approach also offers additional applications, including an importance-based viewpoint-selection guide, and a means of enhancing object features and producing nonphotorealistic object visualizations

Comunicar la ciudad desde el paisaje: hacia una teoría del landscape branding

The need to decode landscape meanings, the society- landscape interaction (intra- and inter-personal communication) and, more recently, the uses of landscape as a territorial sight linked to advertising communication, citymarketing or place branding (mass communication) highlights the study of landscape persuasion, which includes clear emotional, symbolic and, therefore, communicative aspects. The landscape, as a territory image or face, gathers the essence of the implicit message in the space, thus working as a great metaphor for city communication. Regarding the foregoing, specific communication research with intangible landscapes —together with the recent emergence of emotional geographies— suggests a new territorial message theory based on the union of geographical, landscape, emotional and communicational variables. Landscape has historically been studied by geographers, architects, historians or sociologists, among others researchers, but it has not been analysed from communicational viewpoints. In this sense, the proliferation of analyses highlighting the role played by the territory as a communication mediator in the interaction process between society and its spaces (cognition and/or perception) is also remarkable. Current sales of territorial identities lead to increases in the production of territory brands, which have gathered a noticeable relevance within the last years.
