Screening Vector Field Modifications of General Relativity

A screening mechanism for conformal vector-tensor modifications of general relativity is proposed. The conformal factor depends on the norm of the vector field and makes the field to vanish in high dense regions, whereas drives it to a non-null value in low density environments. Such process occurs due to a spontaneous symmetry breaking mechanism and gives rise to both the screening of fifth forces as well as Lorentz violations. The cosmology and local constraints are also computed.Comment: 10 pages, 4 figures, revised version, to be published in PL

Dashboards in smart city’s sustainability performance measurement through business intelligence

Project Work presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business IntelligencePeople’s concentration in urban areas is causing our society significant challenges because of a high populational density in mega-cities. These mega-cities cannot meet and balance their inhabitants’ needs, making it hard to develop an economy to increase their quality of life and improve cities’ surrounding environment and social communities. For cities to grow, considering the three pillars proposed by the sustainable development concept, which traces back to 1980 and supported by OECD, these cities building must meet today's society’s needs without risking future generations’ needs. Following the smart city concept means that decisions taken now must consider the impact on the economy, environment, and society altogether to avoid putting at risk the needs of today’s society, especially its future generations’ well-being. OECD expects this concept to change society’s view on its relationship with the world, hoping the community understands that our planet is an ecosystem that provides vital services. These critical services comprise food, clean water, oxygen, bacterial waste processing, citing a few, and conclude that its survival depends on the environment. The smart city concept aims to address these issues through the simultaneous management of these three pillars and is gaining strength with the latest technological development because it leverages information and communication technologies to collect data to monitor cities’ growth. Besides, smart cities can play a vital role in the world’s climate change by reducing carbon footprint and the usage of cities’ non-renewable energy sources while socially developing its communities and promoting equity between its inhabitants. However, for smart cities to realize all the benefits it proposes, the data collected must support informed decisions. This master project uses business intelligence methods, technologies, and tools to create a strategic performance dashboard using a correlational study based on data made available at European Commission’s Eurostat portal. Business performance management principles guide the strategic dashboard creation to monitor smart city strategic performance under the light of the triple bottom line concept

Entre o curso tradicional e o curso experimental da Faculdade de Medicina-USP: a experiência da pedagoga Maria Cecília Ferro Donnangelo, 1968-1976

As mudanças trazidas pela ditadura militar no Brasil alteraram de forma decisiva a vida institucional da Faculdade de Medicina da USP. Entre a complexidade de uma escola médica sob a pressão político-institucional que se instaurava, a criação de um curso médico capaz de oferecer a formação de um “novo” profissional, movimento nascido das hostes oposicionistas ao regime, redundou numa divisão curricular e de seus alunos. De um lado o curso que vinha se dando até então, o Curso Tradicional, por outro lado uma proposta curricular do então chamado Curso Experimental, que mesmo tendo uma vida curta, entre 1968-1974, possibilitou uma série de experiências nunca pensadas ou permitidas no que dizia respeito ao ensino e prática da medicina. Dentre os professores interessados em alavancar tal proposta inovadora, é interessante notar a presença de Maria Cecília Ferro Donnangelo, figura intelectual das mais relevantes no campo da Saúde Coletiva brasileira e que teve sua trajetória biográfica entrelaçada a esse acontecimento de dimensão pedagógica e política. Acompanhar tal experiência, entre avanços e recuos, faz parte da centralidade deste estudo
