This paper reviews existing literature on spatial metrics, presentinga portfolio of metrics addressingthe spatial patterns of growing and shrinking citiesand discussing their potential and limitations.A wide and diverse set of spatial metrics was found. While these metrics address most of the identified spatial patterns of urban growth, spatial metrics used in urban shrinkage studies are much scarcer and not nearly sufficient to provide a comprehensive assessment of its spatial patterns. The paper concludes that there is a great potential for the development of new spatial metrics or mixed indicators, particularly in shrinkage contexts.The paper builds on recent literature that has been prolific in reviewing and developing metrics for particular spatial patterns (notably patterns of urban sprawl), but considers a very broad and multidisciplinary set of metrics, and focuses not only on the outcomes of urban growth but also on those of the increasingly common shrinking phenomenon.

Urban passenger mobility has undergone significant changes over the past few decades with travel patterns becoming increasingly more complex and difficult to predict and manage. There is an extensive discussion in the literature on the interaction of land use and transport and of their combined influence on mobility patterns. However, this vast but somehow disarticulated research field has been, so far, unable to build consensus. There is clearly a need for further research in order to shed light on the intricate web of forces acting on urban structure and travel behaviour to encourage practical implementation of integrated land-use and transport policies. In this paper we discuss how different metropolitan structures constrain mobility choices made available to their inhabitants. The structural accessibility layer was used to analyze the current land-use and transport conditions provided by two distinct metropolitan areas—Greater Copenhagen and Greater Oporto. Urban structure is regarded here as an enabler of travel choices, and its role in mobility management is discussed under this perspective, looking not at how land-use and transport policies can be used to influence travel behaviour but highlighting that these policies are crucial for providing baseline conditions for sustainable travel choices and have a role in constraining unsustainable ones. This analysis reveals the sustainability of mobility choices made available by each urban structure analyzed. Comparison of potential mobility (enabled by urban structure) with actual mobility choices reveals the role of urban structure and of urban planning in mobility management, highlighting its role in enabling desired, and constraining undesired, travel choices.

In a time of data science, online crowdsourced data and advanced data analytics would be a waste of resources and knowledge if these tools wouldn't assist urban planning. This paper uses sentiment analysis to understand policy debates' present in online media in a re-urbanized city and discusses how these tools and new datasets can help planners and inform new waves of policy by including groups that tend to be underrepresented in traditional consultation meetings. Modern reurbanization is an emergent phenomenon that occurs in cities that experienced urban shrinkage in the past decades. Urban policies proposed to the "new" regrowing cities should meet challenges of old shrinking consequences and new regrowing demands. Nowadays, policy-makers need to hear the voice from different age groups, some use new, non-traditional media in policy debates. Online media data has the potential to provide quasi-live feedbacks, to supply the traditional opinion surveys. We applied sentiment analysis in the selected casethe Integrated Urban Development Concept (INSEK) Leipzig 2030to evaluate public opinion. While results show that public attention was low, the policy seems to be welcome, with the public showing more interests in regrowth topics than shrinkage issues.

Introdução: Os Tumores Sudoríparos (TS) constituem um conjunto heterogéneo de neoplasias epiteliais raras que podem colocar problemas de diagnóstico diferencial com outras neoplasias cutâneas mais frequentes. Material e métodos: Realizámos este trabalho com vista à caracterização epidemiológica da população portadora de TS de natureza benigna e maligna, diagnosticados com base na avaliação histológica de biopsias incisionais e excisionais realizadas num período de 10 anos (entre 1999 e 2008) no Serviço de Dermatologia dos HUC, excluindo todas as recidivas e/ou persistências de neoplasias previamente diagnosticadas. Foi avaliada a idade e sexo dos doentes, diagnóstico clínico inicial, tipo de neoplasia e sua localização. Resultados: Foram diagnosticados 153 TS naquele período, 92,2% dos quais de natureza benigna. O hidrocistoma foi o tumor benigno mais frequente (31,3%); dos tumores malignos, 50% eram porocarcinomas. Mais de metade de todos os tumores localizava-se na cabeça, e cerca de 25% nos membros inferiores, com particular predomínio de poromas nesta última localização. Observou-se predominância geral do sexo feminino (58,8%). De uma forma geral, houve concordância entre diagnóstico clínico e histológico em apenas 24,8% dos casos. Nos casos discordantes, a hipótese clínica de carcinoma basocelular foi a mais comum (19,6%). Conclusões: Os TS são entidades dificilmente reconhecíveis na prática clínica; o seu diagnóstico é, na maioria dos casos, histológico, e frequentemente difícil. Sendo patologias raras, o conhecimento da sua epidemiologia é funda- mental para uma abordagem adequada.PALAVRAS-CHAVE – Tumores Anexiais; Neoplasias das Glândulas Sudoríparas; Hidrocistoma; Poroma; Porocarci- noma.
