The aim of this study is to apprehend the function of the stone enclosures during the Neolithic and the Bronze Age. Some enclosures well positioned in the Corsican chronology have been chosen to show an evolution of their dimensions, of dry-stone techniques used and of the function of the structures excavated within enclosures. The results prove that during the Neolithic, the whole habitat is i...

In order to control cyanobacteria blooms with silver carp in Lake Taihu, an in situ experiment was carried out by stocking silver carp at a biomass of 35, 70, and 150 g m-3 and no carp control in waterproof enclosures. Physicochemical water parameters and biomass of plankton were measured in enclosures to evaluate the suitable stocking density of silver carp for relieving internal nutrients and...

We examined growth of recently settled juvenile red drum in salt marsh, seagrass, oyster reef, and on nonvegetated bottom areas in the Galveston Bay system of Texas (USA). We estimated growth using otolith microstructure from free-ranging fish collected in different habitat types and also measured growth of red drum in experimental enclosures where fish movement was restricted. Otolith growth w...

Starting from the analysis of Marx’s Chapter 26 first volume Capital, this article describes Marxian emphasis on extremely violent aspects—a list main cases is also provided—of so-called “enclosures” as fundamental procedures that favored “primitive accumulation”, is, social and economical step led to capitalism. The characterized primitive accumulation process, violently expropriating peasants...

In less intensive shrimp culture systems, polychaetes are known to be a major food item of several penaeid species. Under these conditions, very little is known about their population dynamics and the possible interactions with penaeid predation and artificial feeding. This work examined the effects of Penaeus subtilis, predation, stocking density and supplemental feeding on the population dyna...

This paper suggests that LIS might benefit from critical political economy as a way of theorizing and responding to enclosures of information commons. The autonomist Marxist re-invigoration of ‘primitive accumulation’ offers a register for apprehending contemporary erosions of the commons. Autonomist Marxism also helps conceptualize resistance to enclosures. Résumé:

We introduce a new method of obtaining guaranteed enclosures of the eigenvalues of a variety of self-adjoint differential and difference operators with discrete spectrum. The method is based upon subdividing the region into a number of simpler regions for which eigenvalue enclosures are already available.

We give the first polynomial-time algorithm for the problem of finding a minimumperimeter k-gon that encloses a given n-gon. Our algorithm is based on a simple structural result, that an optimal k-gon has at least one “flush” edge with the ngon. This allows one to reduce the problem to computing the shortest k-link path in a simple polygon. As a by-product we observe that the minimum-perimeter ...
