Approximation and convergence of solutions to semilinear stochastic evolution equations with jumps

We prove that the mild solution to a semilinear stochastic evolution equation on a Hilbert space, driven by either a square integrable martingale or a Poisson random measure, is (jointly) continuous, in a suitable topology, with respect to the initial datum and all coefficients. In particular, if the leading linear operators are maximal (quasi-)monotone and converge in the strong resolvent sense, the drift and diffusion coefficients are uniformly Lipschitz continuous and converge pointwise, and the initial data converge, then the solutions converge.Comment: 28 pages, no figure

Circular health: a needed approach to promote health and prevent pandemics and other health hazards

SARS-Cov-2 is a perfect example of the intimate relationship between human, animal and environmental health. Circular health goes beyond the biomedical concept of health, operating on the interface between individuals, microorganisms and ecosystems. The World Health Organization endorses this concept and stresses the importance of protecting the environment and addressing and reversing the negative impact of climate change. The application of circular health to the governance for population health is based on protection of all forms of life, interdisciplinarity, involvement of all of society, big data, artificial intelligence, and correct scientific information. It also considers a combination of health, environmental, social and economic problems caused by the synergistic interaction between the acute diseases - in this case caused by SARS-Cov-2, and a number of non-transmittable chronic pathologies. Disinformation and misuse of social media could be more dangerous for the pandemic's development than the virus itself. The adoption of circular health is an urgent necessity in restructuring development policies and making them more effective and sustainable, and protecting and promoting individual and collective health. Within public health, circular health should urgently become the mainstream approach to prevent pandemics and other health hazards. Given the many social, economic, and cultural changes undergoing in the countries of the South-Eastern European Network the conceptual and policy framework related to circular health could be of great value in further advancing progress in this part of Europe

Stochastic FitzHugh-Nagumo equations on networks with impulsive noise

We consider a system of nonlinear partial differential equations with stochastic dynamical boundary conditions that arises in models of neurophysiology for the diffusion of electrical potentials through a finite network of neurons. Motivated by the discussion in the biological literature, we impose a general diffusion equation on each edge through a generalized version of the FitzHugh-Nagumo model, while the noise acting on the boundary is described by a generalized stochastic Kirchhoff law on the nodes. In the abstract framework of matrix operators theory, we rewrite this stochastic boundary value problem as a stochastic evolution equation in infinite dimensions with a power-type nonlinearity, driven by an additive L\'evy noise. We prove global well-posedness in the mild sense for such stochastic partial differential equation by monotonicity methods.Comment: 18 pages. Minor revisio

Socioenvironmental networks and international cooperation: The Global Alliance for Recycling and Sustainable Development- GARSD

Networks of nongovernmental organizations dedicated to socio-environmental issues have emerged in recent decades. The involvement of these networks in the international sphere has enabled new approaches to international cooperation. This article introduces the concept of international cooperation and the Global Alliance for Recycling and Sustainable Development (GARSD), a socio-environmental network created by a coalition of NGOs dedicated to promoting recycling of municipal solid waste. This article is the result of a doctoral study conducted using documentary analysis, participant observation and other qualitative data collection methods.  The study conclusively finds that it is neessary to analyze the work of these non-state actors within the context of international cooperation between nation states and the possibility of (re)creating political-territorial arrangements, such as networks comprising a variety of actors especially geared towards socio-environmental issues.  Durante as últimas décadas, surgiram redes de organizações não governamentais que se dedicam aos temas socioambientais. O envolvimento dessas redes com a esfera internacional ocasiona novas abordagens para a cooperação internacional. Apresentar o conceito de cooperação internacional e a rede socioambiental Global Alliance for Recycling and Sustainable Development - GARSD é o objetivo deste artigo. A GARSD, é resultado da coalização de organizações não governamentais dedicadas à promoção da reciclagem de resíduos sólidos urbanos. O artigo é o resultado de pesquisa realizada em processo de doutoramento, que utilizou por procedimentos metodológicos a análise documental, pesquisa participante e a coleta de dados de abordagem qualitativa.  Conclusivamente, torna-se inerente analisar as atuações destes atores não estatais diante das relações de cooperação internacional estabelecidas entre Estados Nacionais na possibilidade para a (re)criação de arranjos político-territoriais como a construção de redes entre os diversos atores, especialmente, nos temas socioambientais.
