The spectacular development of medical knowledge over the last two centuries has brought intrusive advances in the capabilities of medical technology. These advances have been remarkable over the last century, but especially over the last few decades, culminating in such high technology interventions as heart transplants and renal dialysis. These increases in medical powers have attracted societal interest in acquiring more such knowledge. They have also spawned concerns regarding the use of human subjects in research and regarding the byproducts of (...) basic research as in the recent recombinant DNA debate. As a consequence of the development of new biomedical knowledge, physicians and biomedical scientists have been placed in positions of new power and responsibility. The emergence of this group of powerful and knowledgeable experts has occasioned debates regarding the accountability of physicians and biomedical scientists. But beyond that, the very investment of resources in the acquisition of new knowledge has been questioned. Societies must decide whether finite resources would not be better invested at this juncture, or in general, in the alleviation of the problems of hunger or in raising general health standards through interventions which are less dependent on the intensive use of high technology. To put issues in this fashion touches on philosophical notions concerning the claims of distributive justice and the ownership of biomedical knowledge. (shrink)

The general pattern of Christian children’s ministry has been for adults to deliver structured programs to children. Drawing on the biblical imperative of hospitable space, a more profound understanding is to provide bounded opportunities for children themselves to engage in missional ministry. Implications are suggested for local church ministry and Christian parenting.

We have compared two different laser-induced optical light traps for their utility in moving organelles within living animal cells and walled fungal cells. The first trap employed a continuous wave neodymium-yttrium aluminum garnet laser at a wavelength of 1.06 micron. A second trap was constructed using a titanium-sapphire laser tunable from 700 to 1000 nm. With the latter trap we were able to achieve much stronger traps with less laser power and without damage to either mitochondria or spindles. Chromosomes and (...) nuclei were easily displaced, nucleoli were separated and moved far away from interphase nuclei, and Woronin bodies were removed from septa. In comparison, these manipulations were not possible with the Nd-YAG laser-induced trap. The optical force trap induced by the tunable titanium-sapphire laser should find wide application in experimental cell biology because the wavelength can be selected for maximization of force production and minimization of energy absorption which leads to unwanted cell damage.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

Once God is no longer recognized as the ground and the enforcer of morality, the character and force of morality undergoes a significant change, a point made by G.E.M. Anscombe in her observation that without God the significance of morality is changed, as the word criminal would be changed if there were no criminal law and criminal courts. There is no longer in principle a God's-eye perspective from which one can envisage setting moral pluralism aside. In addition, it becomes impossible (...) to show that morality should always trump concerns of prudence, concerns for one's own non-moral interests and the interests of those to whom one is close. Immanuel Kant's attempt to maintain the unity of morality and the force of moral obligation by invoking the idea of God and the postulates of pure practical reason are explored and assessed. Hegel's reconstruction of the status of moral obligation is also examined, given his attempt to eschew Kant's thing-in-itself, as well as Kant's at least possible transcendent God. Severed from any metaphysical anchor, morality gains a contingent content from socio-historical context and its enforcement from the state. Hegel's disengagement from a transcendent God marks a watershed in the place of God in philosophical reflections regarding the status of moral obligations on the European continent. Anscombe is vindicated. Absent the presence of God, there is an important change in the force of moral obligation. (shrink)

When considering the interactions between rhetoric and argumentation, readers of this journal will no doubt be reminded of the seminal work of Henry W. Johnstone Jr. (1959; 1978) who gathered both concerns together in ways that were designed to engage philosophers and persuade them of the intellectual seriousness of both enterprises. He was, of course, a principal force among those who brought Chaïm Perelman’s work to the attention of audiences in North America, and he himself entered into deep and fruitful (...) dialogues with Perelman by way of reviewing the value that rhetoric brought to argumentation and logic, as well as to philosophy generally. His interest in philosophical argumentation prompted an early .. (shrink)

The following statement is a report of the Committee on Philosophy in Education of the American Philosophical Association and was approved by the Association's Board of Officers in September, 1959. The Committee was composed of the following: C. W. Hendel, Chairman, H. G. Alexander, R. M. Chisholm, Max Fisch, Lucius Garvin, Douglas Morgan, A. E. Murphy, Charner Perry, and R. G. Turnbull. Primary responsibility for the preparation of this report belonged to a subcommittee composed of Roderick M. Chisholm, Chairman, (...) H. G. Alexander, Lewis Hahn, Paul C. Hayner, and Charles W.

Books of extracts are often written to celebrate a reputation, or to move the reader to greater exertions by the words of the great. Neither of these reasons account for the assembling of this selection. For the traditional book of extracts reflects a traditional conception of their role, and below this conception is rejected. Rather, these extracts are thought of as working documents, selected to provide an occasion for critical and reflective thought, and presented in an order designed to ease (...) the strain we always feel when we think warily, acutely, and yet receptively. This book then deals with that contribution to discussion made by four past educationists. It is interesting to note how long their writing has formed part of the subject-matter of courses, without any precise ideas as to where they fit in the scheme of things. The layout of this introduction and the ordering of the following extracts is intended to try and help meet present needs. (shrink)
