Current views of the control of complex, purposeful movements acknowledge that organizational processes must reconcile multiple concerns. The central priority is of course accomplishing the actor's goal. But in specifying the manner in which this occurs, the action plan must accommodate such factors as the interaction of mechanical forces associated with the motion of a multilinked system (classical mechanics) and, in many cases, intrinsic bias toward preferred movement patterns, characterized by so-called “coordination dynamics.” The most familiar example of the latter (...) is the symmetry constraint, where spatial trajectories and/or temporal landmarks (e.g., reversal points) of concurrentlymoving body segments (limbs, digits, etc.) exhibit mutual attraction. The natural coordination tendencies that emerge through these constraints can facilitate or hinder motor control, depending on the degree of congruency with the desired movement pattern. Motor control theorists have long recognized the role of classical mechanics in theories of movement organization, but an appreciation of the importance of intrinsic interlimb bias has been gained only recently.Although detailed descriptions of temporal coordination dynamics have been provided, systematic attempts to identify additional salient dimensions of interlimb constraint have been lacking. We develop and implement here a novel method for examining this problem by exploiting two robust principles of psychomotor behavior, the symmetry constraint and the Two-Thirds Power Law. Empirical evidence is provided that the relative spatial patterns of concurrently moving limbs are naturally constrained in much the same manner as previously identified temporal constraints and, further, that apparent velocity interference is an indirect, secondary consequence of primary spatial assimilation. The theoretical implications of spatial interference are elaborated with respect to movement organization and motor learning. The need to carefully consider the appropriate dimensions with which to characterize coordination dynamics is also discussed. (shrink)

Only six men have written a major work on Old Testament ethics in the last hundred years, and only two of these works, both written before 1900, are in English.

In this essay Walter Okshevsky addresses the question of whether a certain form of dialogically derived agreement can function as an epistemic criterion of moral judgment and ground of moral authority. Okshevsky examines arguments for and against in the literature of educational philosophy and develops Jürgen Habermas's affirmative answer as presented in his discourse theory of morality. Habermas's position is articulated as a moral epistemology and is developed through his critique of the “monologism” of certain aspects of Immanuel Kant's (...) moral theory. Okshevsky concludes with a consideration of some educational implications of Habermas's position. (shrink)

In this article, Walter Parker brings structure and agency to the foreground of the current tumult of public schooling in the United States. He focuses on three structures that are serving as rules and resources for creative agency. These are a discourse of derision about failing schools, a broad mobilization of multiculturalism, and an enduring nationalism. Drawing on Anthony Giddens's structuration theory, Parker examines how these discourses figure in redefining school reform, redefining school curricula, and requiring schools once again (...) to serve nationalistic purposes.

Not the least interesting feature in Mr. C. C. J. Webb's new edition of John of Salisbury's Policraticus are the references to the passages of Roman literature from which his author has quoted or borrowed. One cannot speak too highly of the thoroughness with which the editor has carried out this part of his task; that a few cases of borrowing should have passed unnoticed, and the sources of a few quotations evaded his inquiries, was inevitable.

IX. 6. 12. iacere indolem illam Romanam ablatosque cum armis animos; non reddere salutem, non salutantibus dare responsum, non hiscere quemquam prae metu potuisse.

Contr. I. The characters of this declamation are two brothers, at deadly enmity with each other, and the son of one of them, who, when his uncle is reduced to beggary, supports him in spite of his father′s prohibition. Disowned by the latter, he is adopted by his uncle, who presently grows rich—at the very moment when his brother loses everything. The young man again reveals his tender-heartedness, supports the unfortunate man in the face of his adopted father′s orders, and (...) is once more disowned. He pleads his case before a jury.

In a general account of this Livian MS. given in the Classical Review of 1904 I dealt more especially with the text of the first decade; now that my study of its text of the third decade is completed, it is possible to give a brief estimate of its importance and interest in this portion also.
