The increasing availability of passively observed data has yielded a growing interest in “data fusion” methods, which involve merging data from observational and experimental sources to draw causal conclusions. Such methods often require a precarious tradeoff between the unknown bias in the observational dataset and the often-large variance in the experimental dataset. We propose an alternative approach, which avoids this tradeoff: rather than using observational data for inference, we use it to design a more efficient experiment. We consider the case (...) of a stratified experiment with a binary outcome and suppose pilot estimates for the stratum potential outcome variances can be obtained from the observational study. We extend existing results to generate confidence sets for these variances, while accounting for the possibility of unmeasured confounding. Then, we pose the experimental design problem as a regret minimization problem subject to the constraints imposed by our confidence sets. We show that this problem can be converted into a concave maximization and solved using conventional methods. Finally, we demonstrate the practical utility of our methods using data from the Women’s Health Initiative. (shrink)

Business ethics courses have been launched with professors from business pulling on one oar, and professors of philosophy pulling on the other, but they lack a sense of direction. Let's begin with the basics: What is an ehtical decision? More fundamentally, why the interest in professional ethics in the first place?There are over 300 centers for the study of appIied ethics in this country-why? The events which face our society today are outside the business-oriented collection of shared beIiefs that set (...) our pubIic policy agenda. Cur beIiefs are too narrow, thus we see, understand, and control small slices of life.Business ethics should be the study of the structure and impact on us of what we call "business science," e.g., accounting, marketing, economics, law, etc., and the corresponding study of the process of what Carl Jung called individuation: learning to become one's own uniqueself in the face of these bodies of professional knowledge which have structured our lives and charted the direction for our sensibilities for too long.

A humanidade tem sido tomada por angústias tão sutis que, aos poucos, vai se dissolvendo – física e psicologicamente – como se estivesse sendo consumida de dentro para fora. Neste sentido a saída – ainda que imediata e provisória – é propor um jogo de Xadrez com a morte. Não à toa Ingmar Bergman escolhe o Xadrez como a forma da sua personagem desafiar “alguém” tão poderoso. O jogo é um chamamento à razão, à luz capaz de organizar as ideias (...) e dar um rumo à vida.

Ainda que possa ser visto como clichê sob diversos aspectos, o filme “O Céu da Meia-Noite” (dirigido e protagonizado por George Clooney para a Netflix) traz temas reflexivos na perspectiva existencial. Lançado em dezembro de um ano doloroso para a humanidade, ele teve as suas gravações encerradas pouco antes do início da pandemia, ainda que traga uma atmosfera tão soturna quanto a deste momento histórico.

Published under the auspices of The World Institute for Advanced Phenomenological Research and Learning, 19 essays document the April 1998 international congress held at Harvard University. They ponder on such topics as the phenomenology of the experience of enchantment, Leonardo's enchantress, the ambiguous meaning of musical enchantment in Kant's Third Critique, art and the reenchantment of sensuous human activity, the creative voice, the allure of the Naza, Henri Matisse's early critical reception in New York, Zizek's sublimicist aesthetic of enchanted fantasy, (...) and enchantment in Baroque festive court performance in France.

This book disrupts disciplinary boundaries to make a case for the future direction and growth of martial arts studies as a unique field.

We humans are a curious species. Of all the life forms that inhabit the earth, we alone strive to make sense of the world in which we find ourselves. For thousands of years we understood the world through stories. Our ancestors told stories of how the world began, how our people originated and came to be at this place, and how those people across the river or beyond the mountains came to be where they are. Some stories were of animals (...) and plants in our neighborhood, and their powers to help us, feed us, or cure our ailments. But in the last few centuries, starting in Europe and spreading throughout the world, a new way of understanding began competing with storytelling as a means of comprehending our world. Science supplanted storytelling largely because it empowered us to transform the world in ways that were unimaginable to our ancestors. We understand the world scientifically by describing the world instead of by telling stories about it. The stories our ancestors told no longer explain the world, but are data within the world, part of the world that science describes. Our stories have become myths, cultural artifacts that may be interesting and a subject of study, but cannot possibly be true. Yet even in societies that have thoroughly embraced science as a means of understanding the world, myths remain a powerful force. Myth and science exist side by side, often creating confusion and conflict. (shrink)

O início da terceira década do século 21, tão marcado pela globalização tecnológica e virtualização das relações humanas, ainda mantém fortes laços com o obscurantismo religioso da Idade Média. Com outra roupagem, o fanatismo de muitos cristãos das mais variadas igrejas eterniza sentimentos e ações que acreditávamos superados há séculos. A intolerância religiosa, normalmente carregada de outras tantas intolerâncias na pauta moral, revela com clareza que a caça às bruxas nos tempos da chamada Santa Inquisição foi atualizada com sucesso. O (...) Brasil, por exemplo, vive um de seus piores momentos históricos neste sentido, principalmente pelos recorrentes ataques furiosos às religiões de matriz africana e crimes de agressão e morte contra as chamadas minorias sociais.
