There is already a copious literature comparing Claudius' oration on the admission of the primores Galliae into the Roman Senate with Tacitus’ account of the speech and of the opposition's case in Annals 11. 23–4. Yet the Emperor's own purpose in speaking as he did still needs some illumination. Scholarly concentration on technical points about the citizenship, on Claudius’ antiquarianism and on his debt to Livy has been fruitful, but it has often distracted attention from Claudius’ immediate aim. Meanwhile, Tacitus’ (...) interpretation has been insidious in colouring our view of what course of action the imperial orator was trying to defend before the Senate. (shrink)

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional (...) nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg’s Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p < 0.05) was found between nursing students’ professional nursing values and levels of self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses. (shrink)

In a recent paper M.R. Ayers attacks two widely held doctrines: Non-arbitary individuation requires principles of individuation and these are supplies only by sortal general terms. It is possible for an item a to be the same as b but not the same as b.I shall follow Ayers in calling a theory which includes both and ‘conceptualist’ or ‘sortalist’, but I shall not allow him to appropriate the honorific term ‘realist’ for his own theory, which I shall term ‘absolutist’. My (...) sole purpose here is to defend and in turn against Ayers’ attacks on them. Thus I shall ignore intermediate positions which accept but reject or vice-versa.Ayers’ paper is long and in many respects obscure; there are many points in it which require discussion but which can't receive it here for lack of space. In particular, I shall ignore his lengthy comments on the constitutive ‘is’, and also the wider metaphysical remarks in his conclusion and the postscript on Dummett. (shrink)

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.
