The traditional problem of free will has reached an impasse; we are unlikely to see progress without rethinking the terms in which the problem had been cast. Our approach offers an alternative to the standard terms of the debate, by developing an authorially parameterized approach articulated within a two-dimensional semantics for temporal predicates.

The incidence of metastatic medulloblastoma is probably greater than the thirteen documented patients. Case reports of metastatic medulloblastoma must be carefully analysed. We have added two cases which conform to Weiss’ criteria for metastatic disease. The direction and factors influencing spread have been discussed.

Among the instances of apparent illiberality in Plato's Republic, one stands out as especially curious. Long before making a forced return to the cave, and irrespective of the kinds of compulsion operative in such a homecoming, the philosopher-king has been compelled to apprehend the Good (Rep. VII.519c5-d2, 540a3-7). Why should compulsion be necessary or appropriate in this situation? Schooled intensively through the decades for an eventual grasping of the Good, beginning already with precognitive training in music and art calculated to equip the guardian with a natural affinity towards the good and beautiful (Rep. III.401d3-402a4), the fully mature guardian might be expected to leap towards the Good when it is first opportune. For the Good is, according to Plato, the greatest thing to be learned (megiston mathêma; Rep. VI.504e4-5, 505a2). Reflection on these questions permits us to develop a richer appreciation of the forms of necessitation and compulsion Plato envisages for his guardians, which turn out to be primarily merely hypothetical instances of nomic necessitation. It follows that many of Plato's appeals to compulsion are neither coercive nor objectionably authoritarian.

Two different biomimetic strategies were utilized in the formation of magnetite fibers. The first strategy utilized natural (Sphaerotilus natans sheaths) or synthetic (hollow fibers) matrices for magnetite formation. The second strategy made use of an iron-hydroxide intermediate that was subsequently chemically converted to magnetite within the biomimetic matrix. The formation of magnetite was determined by both visual and x-ray diffraction analysis. This process has advantages over conventional routes because of the expense and handling problems associated with the production of ceramic whiskers and fibers. The magnetite formed by this process may prove to have unique properties due to its unusual fiber structure.

In the largely historical and aporetic first book of the De Anima (DA), Aristotle makes what appear to be some rather disturbing remarks about the soul's status as a subject of mental states. Most notably, in a curious passage which has aroused the interest of commentators, he seems to suggest that there is something wrong with regarding the soul as a subject of mental states:

Thus, saying that the soul is angry is the same as if one were to say that the soul builds houses and weaves: for it is perhaps better to say not that the soul pities or learns or thinks, but that the man does [these things] with his soul. (DA 408bll–15)
