The reduction of a quantum mechanical wave function by the entry of a datum into the consciousness of an observer is used, in a semirealistic neurochemical model, to bring about excitation of a nerve cell in that observer's central nervous system. It is suggested that mind can induce muscular movements by choosing to note data originating from specialized elements of the nervous system. Only the freedom to note or not to note a relevant datum is postulated for the observer's mind; (...) the consequences of either choice are deterministic on the neural scale of events, so that quantum indeterminacy is consistent with physiological determinacy. The proposed mind-body coupling depends on the possibility of the biological evolution of a macroscopic device which has strikingly different neural correlates of its pure and mixed quantum states, respectively. An example of such a device is outlined in terms of components which are familiar from existing nervous systems. (shrink)

Wigner's quantum mechanical formulation of the problem of biological replication is examined with special reference to DNA. His necessary condition for replication is that the number of independent equations in his formulation should not exceed the number of unknowns. Explicit hypotheses concerning the relevant collision matrix are proposed without assuming biotonic modifications of quantum mechanics. Schrödinger's description of the gene as a low-temperature solid, combined with the concept of template, is given mathematical expression which fails to satisfy Wigner's necessary condition. (...) The condition is satisfied by a further specialization of the collision matrix, which also implies metabolic stability of the replicating unit. Such metabolic stability is in fact a distinguishing feature of the DNA molecule. (shrink)

Co-published with UCEA, this new textbook tackles Standard #2 of the Professional Standards for Educational Leaders (PSEL)¿Ethics and Professional Norms. This volume includes specific strategies for school leaders to develop knowledge and skills in supporting the learning and development of all students, as well as understanding the dynamics and importance of ethics in leadership practice. By presenting problem-posing cases, theoretical grounding, relevant research, implications for practice, and learning activities, this book provides aspiring leaders with the background, learning experiences, and analytical (...) tools to successfully promote ethical leadership and student success in their contexts. Special features include: ¿ Case Studies¿provide an opportunity to practice ethical reasoning and engage in the discussion of complexities and debates within each case. ¿ Learning Activites¿a range of exercises help readers make connections to the PSEL standard. ¿ Important Resources¿includes resources that support and encourage students to explore each of the chapter¿s elements.
