. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

The Second Edition of Curriculum Theory: Conflicting Visions and Enduring Concerns by Michael Stephen Schiro presents a clear, unbiased, and rigorous description of the major curriculum philosophies that have influenced educators and schooling over the last century. The author analyzes four educational visions—Scholar Academic, Social Efficiency, Learner Centered, and Social Reconstruction—to enable readers to reflect on their own educational beliefs and more productively interact with educators who might hold different beliefs.

Alternative ways of thinking, analysing and performing economic geographies have become increasingly significant in recent years, partly due to the recent financial crisis, which has had social and political consequences throughout the world. Yet there is a danger that the debate about alternatives may become simply a way of fixing global capitalism in its present crisis-ridden form. Instead, the analysis of alternative economic spaces must continue to offer a critique of the very notion of capitalism as a universal, if variable, set of social relations. This important book brings together critical analyses of alterity from across the social sciences and humanities, refining and advancing what alternative economies and polities are, how they are formed, what difficulties and problems they face, and how they might be sustained. A central theme is the need to examine critically both the material contexts and the conceptual categories deployed in the making of alternative economies.
