Ockham realized the value of a careful study and application of the mathematical theory of continuity, even though he possessed no conclusive empirical evidence that it adequately explained the continuity experienced in the world of sense. He also clearly perceived a relation of continuity to infinity, since continuity, as a property of an order which is possible only to a series of terms, must have an infinite number of terms. “A continuous series must have an infinite number of terms.”.

Earth is changing in ways it hasn't for hundreds of thousands of years. At the same time, Christianity is breaking away from its millennium-long geographical and cultural center in the Euro-West. Its growth is in Asia, Africa, and Latin America, primarily in Pentecostal, evangelical, and independent churches. These dramatically changed planetary and ecclesial landscapes have led many to conclude that we need a new way of thinking about our collective existence: who are we and what is the nature of our (...) responsibility in this deeply altered world? To address that question, biblical scholars Bruce C. Birch and Jacqueline E. Lapsley and Christian ethicists Larry L. Rasmussen and Cynthia Moe-Lobeda carry on "a new conversation" that engages how Christians are to understand the authority and use of Scripture, the basic elements of any full-bodied Christian ethic attuned to our circumstances, and the nature of our responsibility to our planetary neighbors and creation itself.

Digital personal data is increasingly framed as the basis of contemporary economies, representing an important new asset class. Control over these data assets seems to explain the emergence and dominance of so-called “Big Tech” firms, consisting of Apple, Microsoft, Amazon, Google/alphabet, and Facebook. These US-based firms are some of the largest in the world by market capitalization, a position that they retain despite growing policy and public condemnation—or “techlash”—of their market power based on their monopolistic control of personal data. We (...) analyse the transformation of personal data into an asset in order to explore how personal data is accounted for, governed, and valued by Big Tech firms and other political-economic actors. However, our findings show that Big Tech firms turn “users” and “user engagement” into assets through the performative measurement, governance, and valuation of user metrics, rather than extending ownership and control rights over personal data per se. We conceptualize this strategy as a form of “techcraft” to center attention on the means and mechanisms that Big Tech firms deploy to make users and user data measurable and legible as future revenue streams.

"This is the book that I have been waiting for for twenty years. With exceptional clarity, Draine introduces the underlying physics and brings the basic pieces together to describe the multiphase structure of the interstellar and intergalactic medium. Combined with many useful tables and figures, this book will rapidly become a hit with students and researchers alike. It continues the fine tradition of Princeton professors writing seminal books on this topic."--Ewine van Dishoeck, Leiden University "A true tour de force, providing (...) a definitive account of the physics of interstellar matter. Written with authority and insight by a master of the subject, Bruce Draine's book will be a treasured guide for new graduate students as well as a comprehensive and rigorous reference for galactic and extragalactic researchers."--Eve Ostriker, University of Maryland "Draine has written an interstellar-medium textbook worthy of Lyman Spitzer, updated thirty years later. His coverage of atomic, molecular, radiative, thermal, and dynamical processes is excellent. Most valuable to students and professionals are the combinations of physical processes with multiwavelength observations appropriate for the modern astronomer."--J. Michael Shull, University of Colorado at Boulder "This book is a comprehensive account of the physical processes that take place in the interstellar medium and that determine its behavior. It is likely to become the bible on the subject."--Alexander Dalgarno, Harvard University "This is an outstanding text on an important topic in astrophysics. Draine carefully goes into the physical processes, providing a unifying discussion that is often missing in other treatments."--Christopher F. McKee, University of California, Berkeley. (shrink)

Three forms of implicit knowledge are presented (functional, structural, and procedural). These forms differ in the way they are made explicit and hence in how they are represented by the individual. We suggest that the framework presented by Dienes & Perner does not account for these differences.

ABSTRACT Alchemy is part of the cultural experience of early modern Europe and yet has had to overcome problems of demarcation to be considered relevant to the history of science. This essay considers historiographical and methodological issues that have affected the gradual demarginalization of alchemy among attempts to explain, and find things out about, nature. As an area of historical study, alchemy relates to the history of science as part of an ensemble of practices that explored the natural world through (...) natural philosophy and speculative traditions and by functioning as a nexus of social and intellectual life.

ABSTRACT:Organizations constitute morally-complex environments, requiring organization members to possess levels of moral courage sufficient to promote their ethical action, while refraining from unethical actions when faced with temptations or pressures. Using a sample drawn from a military context, we explored the antecedents and consequences of moral courage. Results from this four-month field study demonstrated that authentic leadership was positively related to followers’ displays of moral courage. Further, followers’ moral courage fully mediated the effects of authentic leadership on followers’ ethical and (...) pro-social behaviors. Theoretical and practical implications for further integrating the work on moral courage, authentic leadership and ethics are discussed. (shrink)

Human neural organoid research is advancing rapidly. As Greely notes in the target article, this progress presents an “onrushing ethical dilemma.” We can’t rule out the possibility that suff...
