Drawing on the rich recent season of Gramscian philological studies, this book offers a reconsideration of Gramsci's theory of the state and concept of philosophy, arguing that a renewal of the 'philosophy of praxis' constitutes a necessary element in the contemporary revitalisation of Marxism.

According to an established interpretation, the transition from Hegel's materialism to Marx's materialism signifies a progressive development from an abstract-idealist theory of becoming, to a theory of the concrete actions of human beings within history.

It provides an integrated framework for assessment which reflects both practical and academic perspectives. Descriptions of various methods are given, along with examples...

Taking a functional rather than an ecosystem or a utilitarian approach, Thomas and Packham provide a concise account of the structure of woodlands and forests. Using examples from around the world - from polar treelines to savannahs to tropical rain forests - the authors explain the structure of the soil and the hidden world of the roots; how the main groups of organisms which live within them interact both positively and negatively. There is particular emphasis on woodland and forest processes, especially those involving the flow and cycling of nutrients, as well as the dynamics of wooded...
