Neste livro Gombrich discute as idéias e as posturas específicas que tiveram influência decisiva na prática da arte renascentista. Todos os estudos aqui reunidos tratam de algo a que se pode chamar clima renascentista de opiniões sobre a arte, além da influência desse clima sobre a prática e a crítica da arte.

Upshot: In our response we focus on how different types of systems are related from a constructivist perspective, and specifically on the relation between communicational social systems and embodied agency.

An original deep history of the internet that tells the story of the centuries-old utopian dreams behind it—and explains why they have died today Many think of the internet as an unprecedented and overwhelmingly positive achievement of modern human technology. But is it? In The Internet Is Not What You Think It Is, Justin Smith offers an original deep history of the internet, from the ancient to the modern world—uncovering its surprising origins in nature and centuries-old dreams of radically improving (...) human life by outsourcing thinking to machines and communicating across vast distances. Yet, despite the internet’s continuing potential, Smith argues, the utopian hopes behind it have finally died today, killed by the harsh realities of social media, the global information economy, and the attention-destroying nature of networked technology. Ranging over centuries of the history and philosophy of science and technology, Smith shows how the “internet” has been with us much longer than we usually think. He draws fascinating connections between internet user experience, artificial intelligence, the invention of the printing press, communication between trees, and the origins of computing in the machine-driven looms of the silk industry. At the same time, he reveals how the internet’s organic structure and development root it in the natural world in unexpected ways that challenge efforts to draw an easy line between technology and nature. Combining the sweep of intellectual history with the incisiveness of philosophy, The Internet Is Not What You Think It Is cuts through our daily digital lives to give a clear-sighted picture of what the internet is, where it came from, and where it might be taking us in the coming decades.

This article proposes a geostatistical solution for area-to-point spatial prediction (downscaling) taking into account boundary effects. Such effects are often poorly considered in downscaling, even though they often have significant impact on the results. The geostatistical approach proposed in this article considers two types of boundary conditions (BC), that is, a Dirichlet-type condition and a Neumann-type condition, while satisfying several critical issues in downscaling: the coherence of predictions, the explicit consideration of support differences, and the assessment of uncertainty regarding the (...) point predictions. An updating algorithm is used to reduce the computational cost of area-to-point prediction under a given BC. In a case study, area-to-point prediction under a Dirichlet-type BC and a Neumann-type BC is illustrated using simulated data, and the resulting predictions and error variances are compared with those obtained without considering such conditions.
