RESUMO
Measuring event concentration often involves identifying clusters of events at various scales of resolution and across different regions. In the context of a city, for example, clusters may be characterized by the proximity of events in the metric space. However, events may also occur over urban structures such as public transportation and infrastructure systems, which are naturally represented as networks. Our work provides a theoretical framework to determine whether events distributed over a set of interconnected nodes are concentrated on a particular subset. Our main analysis shows how the proposed or any other measure of event concentration on a network must explicitly take into account its degree distribution. We apply the framework to measure event concentration (i) on a street network (i.e., approximated as a regular network where events represent criminal activities); and (ii) on a social network (i.e., a power law network where events represent users who are dissatisfied after purchasing the same product).

The idea that the Holocene is over and a new human-dominated geological epoch, the Anthropocene, is in progress has been widely discussed. The article aims to outline the published definitions and current patterns on the Anthropocene, highlighting an agenda of emerging risks, challenges and possibilities for the health of the world's population in this new era. We performed a review on the complexities of planetary health in the Anthropocene, which generated 42 initial references for full-text reading; we selected 25 of them and carried out analysis and interpretation. Anthropogenic activities have increasing impacts on the environment and a fundamental change in the relationship between humans and the terrestrial system, in many ways that exert intentional and unintentional influences on natural and social processes. The burgeoning literature on health promotion and global public health talks about the anthropogenic forces, claiming a solid critical theory of action to confront, modify and reduce the deleterious effects of such forces. For that reason, the 23rd IUHPE World Conference on Health Promotion, scheduled to be held in New Zealand in 2019, emphasizes the theme 'Promoting Planetary Health and Sustainable Development for All'. It recognizes that the current paradigm of economic unlimited growth and exploitation of limited natural resources is unfair and unsustainable, leading to geopopulational and temporal inequities between generations.

A cidade de São Paulo enfrenta uma crescente demanda por obras de infra-estrutura. Para ordenar essa ocupação, propõe-se que o Poder Público promova as regulamentações legais e um plano diretor, fundamentados nas características geológico-geotécnicas locais e no desenvolvimento de pesquisas geoecnológicas nas universidades e institutos de pesquisa, sob o conceito da sustentabilidade.
