Introduction. During the past two decades philosophers of psychology have considered a large variety of computational models for philosophy of mind and more recently for cognitive science. Among the suggested models are computer programs, Turing machines, pushdown automata, linear bounded automata, finite state automata and sequential machines. Many philosophers have found finite state automata models to be the most appealing, for various reasons, although there has been no shortage of defenders of programs and Turing machines. A paper by Arthur Burks (...) convinced me long ago that “all natural human functions” are, or can be fruitfully modeled to be, finite state automata with output. Further work in the field has reinforced this conviction. There is room, however, for the use of any of the above models in philosophy of mind and in the ongoing development of cognitive science.

In this paper it is argued that certain stimulus-response learning models which are adequate to represent finite automata (acceptors) are not adequate to represent noninitial state input-output automata (transducers). This circumstance suggests the question whether or not the behavior of animals if satisfactorily modelled by automata is predictive. It is argued in partial answer that there are automata which can be explained in the sense that their transition and output functions can be described (roughly, Hempel-type covering law explanation) while their (...) behaviors are in principle not predictable short of possession of their complete histories or of information concerning present internal states by indirect observation.

Calcium ions act as modulators of many fundamental processes in eukaryotic cells. Although these processes apparently involve initial interactions between calcium ions and cell membranes, the identity of the putative membrane Ca2+‐binding proteins has until recently been obscure. This article describes a recently discovered family of mammalian membrane proteins, of perhaps ancient origin, that may fulfil this function.

Ethical fiduciaries in health care lack sufficient criteria for making ethical decisions. The authors introduce criteria from The Theory of Comfort as developed in the nursing literature. According to the theory, comfort is based in observation, measurable, and represents a nearly universal human need and interest. Use of the theory is illustrated through three case studies.

In the mid-nineteenth century, healthcare delivery began transitioning from an individual, private payment model to a third-party payment model, dominated by the insurance industry. During the same time, productivity shifted from a transformational model, centered on the provider-patient relationship, to a transactional model, based on the distribution of services. The emergence of medical insurance and other third-party payers removed providers and patients from discussions about treatment plans, payment, and risk. This resulted in a weakening, if not fracturing, of the provider-patient (...) relationship. All healthcare providers enter their profession to care for people, yet what has most frequently been lost in the transformed relationship over the past century is context, communication, and trust—all elements of a relational ethic, or what ethicist and psychologist Carol Gilligan first described as, “the ethics of care.” This loss of relationality has led to a model of healthcare delivery that is fractured, isolated, and uncoordinated, with an epidemic of medical errors that by some estimates results in the death of approximately 400,000 individuals per year. Thus far, isolated foci on patient quality, outcomes, and safety have been feckless and unimpressive. However, new advanced payment models, such as value-based purchasing and patient-centered medical homes, have the potential to reduce medical error by addressing its root cause. In linking payment to factors such as context, communication, and trust, they bring relationality back into the healthcare system. This essay traces the historic devolution of the provider-patient relationship and the promise of new payment models to restore it. (shrink)

. The seemingly disparate systems of philosophical Taoism and modern biological science are compared. A surprising degree of similarity is found in their views on death, reversion , complementary interactions of dichotomous systems, and the place of humans in the universe. The thesis is advanced that these similarities arise quite naturally, since both systems base their knowledge upon objective observation of natural phenomena. Substantial differences between the two systems are recognized and examined regarding verbal argument, machinery, and experimentation. The Taoists' (...) relationship to Chinese alchemy and the biologists' to technology are claimed to mitigate their attitudes toward experimentation. (shrink)
