Hemiparetic stroke in adulthood often results in the grouped movement pattern of the upper extremity flexion synergy thought to arise from an increased reliance on cortico-reticulospinal pathways due to a loss of lateral corticospinal projections. It is well-established that the flexion synergy induces reaching constraints in individuals with adult-onset hemiplegia. The expression of the flexion synergy in individuals with brain injuries onset earlier in the lifespan is currently unknown. An early unilateral brain injury occurring prior to six months post full-term (...) may preserve corticospinal projections which can be used for independent joint control and thus minimizing the expression of the flexion synergy. This study uses kinematics of a ballistic reaching task to evaluate the expression of the flexion synergy in individuals with pediatric-onset hemiplegia (PH) ages six to seventeen years. Fifteen individuals with brain injuries before birth (n = 8) and around full-term (n = 7) and nine age-matched controls with no known neurological impairment completed a set of reaches in an admittance controlled robotic device. Descending drive, and the possible expression of the upper extremity flexion snergy, was modulated by increasing shoulder abduction loading. Individuals with early PH achieved lower peak velocities when reaching with the paretic arm compared to controls however no differences in reaching distance were found between groups. Relative maintenance in reaching seen in individuals with early brain injuries highlights minimal expression of the flexion synergy. We interpret this conservation of independent control of the paretic shoulder and elbow as the use of more direct corticospinal projections instead of indirect cortico-reticulospinal pathways used in individuals with adult-onset hemiplegia.

Morality is often thought of as non-rational or sub-rational. In Moral Notions, first published in 1967, Julius Kovesi argues that the rationality of morality is built into the way we construct moral concepts. In showing this he also resolves the old Humean conundrum of the relation between 'facts' and 'values'. And he puts forward a method of reasoning that might make 'applied ethics' (at present largely a hodge-podge of opinions) into a constructive discipline. Kovesi's general theory of concepts - (...) important in its own right - is indebted to his interpretation of Plato, and his three papers on Plato, first published here, explain this debt. This new edition of Moral Notions also includes a foreward by Philippa Foot, a biography of the author, and a substantial afterword in which the editors, Robert Ewin and Alan Tapper, explain the signficance of Kovesi's work.

Liebe Grete Herrmann, besten Dank für Ihren Brief vom 19.5! Auch ich freue mich, Sie auf dem Pariser Kongreß zu sehen; wahrscheinlich werde ich auch an der vorangehenden Positivistentagung teilnehmen, also schon am 29.7. in Paris sein. Es interessiert mich, diese antimetaphysischen Metaphysiker einmal aus der Nähe zu beobachten. Ich werde sehen, es so einzurichten, daß ich eventuell auch nach dem Hauptkongreß noch einige Tage in Paris sein kann, um die von Ihnen angeregten Diskussionen mitzuführen. Jedenfalls hoffe ich auf einige (...) gründliche Gespräche mit Ihnen. (shrink)

In this book, Julius M. Moravcsik disputes that a natural language is not and should not be represented as a formal language. The book criticizes current philosophy of language as having an altered focus without adjusting the needed conceptual tools. It develops a new theory of lexical meaning, a new conception of cognition-humans not as information processing creatures but as primarily explanation and understanding seeking creatures-with information processing as a secondary, derivative activity. In conclusion, based on the theories of (...) lexical meaning and cognition, this work sketches an argument showing that the human understanding of human understanding must always remain just partial.

Introduction.--The literary form and philosophical content of the Platonic dialogue.--Plato's method of dialectic.

The increasing prevalence of ecologically sustainable products in consumer markets, such as organic produce, are generally assumed to curtail anthropogenic impacts on the environment. Here I intend to present an alternative perspective on sustainable production by interpreting the relationship between recent rises in organic agriculture and greenhouse gas emissions from agricultural production. I construct two time series fixed-effects panel regressions to estimate how increases in organic farmland impact greenhouse gas emissions derived from agricultural production. My analysis finds that the rise (...) of certified organic production in the United States is not correlated with declines in greenhouse gas emissions derived specifically from agricultural production, and on the contrary is associated positively overall agricultural greenhouse gas emissions. To make sense of this finding, I embed my research within the conventionalization thesis. As a result I argue that the recent USDA certification of organic farming has generated a bifurcated organic market, where one form of organic farming works as a sustainable counterforce to conventional agriculture and the other works to increase the economic accessibility of organic farming through weakening practice standards most conducive to reducing agricultural greenhouse gas output. Additionally, I construct my own theoretical framework known as the displacement paradox to further interpret my findings. (shrink)

Marx criticized political economy for propounding an inverted, mystical view of economic reality. But he went beyond asserting the falsity and apologetic character of the doctrine to characterize it as reflecting a social practice of inversion or mystification — an inverted social world — in which individuals incorporate their own actions into a process whose dynamic lies beyond their control. Caught up in this process, individuals confront aspects of their own agency in the alien or reified form of a given, (...) determining reality. Marx leaves unclear exactly how the process exerts and maintains its hold on agents, the nature of the reasons they might have for wanting to free themselves of it, and under what conditions they could do so. However, it is possible to abstract somewhat from Marx's specific concerns and to model a self-reproducing practice of reification that works through the informational environment of decision. Though of wider interest, this more general conception can shed light on the nature and critique of Marx's inverted world. It draws on conceptual resources from decision theory, game theory and general equilibrium theory. (shrink)

Julius Evola was a renowned Dadaist artist, Idealist philosopher, critic of politics and Fascism, 'mystic, ' anti-modernist, and scholar of world religions. Evola was all of these things, but he saw each of them as no more than stops along the path to life's true goal: the realisation of oneself as a truly absolute and free individual living one's life in accordance with the eternal doctrines of the Primordial Tradition. Much more than an autobiography, The Cinnabar Path in describing (...) the course of Evola's life illuminates how the traditionally-oriented individual might avoid the many pitfalls awaiting him in the modern world. More a record of Evola's thought process than a recitation of biographical facts, one will here find the distilled essence of a lifetime spent in pursuit of wisdom, in what is surely one of his most important works.
