The Ore condition, affiliated operators, and the lamplighter group
Let G be the wreath product of Z and Z/2, the so called lamplighter group and
k a commutative ring. We show that kG does not have a classical ring of
quotients (i.e. does not satisfy the Ore condition). This answers a Kourovka
notebook problem. Assume that kG is contained in a ring R in which the element
1-x is invertible, with x a generator of Z considered as subset of G. Then R is
not flat over kG. If k is the field of complex numbers, this applies in
particular to the algebra UG of unbounded operators affiliated to the group von
Neumann algebra of G. We present two proofs of these results. The second one is
due to Warren Dicks, who, having seen our argument, found a much simpler and
more elementary proof, which at the same time yielded a more general result
than we had originally proved. Nevertheless, we present both proofs here, in
the hope that the original arguments might be of use in some other context not
yet known to us.Comment: LaTex2e, 7 pages. Added a new proof of the main result (due to Warren
Dicks) which is shorter, easier and more elementary, and at the same time
yields a slightly more general result. Additionally: misprints removed. to

Should Corporate Farming be Limited in the United States?: An Economic Perspective
Farming in the United States has changed drastically over the last century. Technology has improved farmers’ ability to produce. Economies of scale available from new technology have led to restructuring in the agricultural industry. Fewer and larger farms are now the norm. As technology improved, corporations began to increase activity in agricultural sectors. Sectors such as livestock are more susceptible to corporate farming. Many Americans are opposed to corporate farming because of the perceived negative effects on rural America. Limiting corporate farming, though, is not a good way to protect rural America. Corporate farming leads to a more efficient industry and more social benefits. This paper identifies the alleged negative effects of corporate farming, why it is occurring, and why it should not be opposed
WHO OWNS NATURAL RESOURCES IN THE UNITED STATES AND CANADA?
Property rights are social definitions; they exist as long as the society is willing to enforce them. If enforcement is missing, they cease to exist. The reasons for changes might be market conditions, popular sentiments, scientific knowledge, new technologies, lobbying, or legal battles. Biotechnologies are already having profound effects on how we organize property rights for natural resources. Resource rights change as our understandings and sentiments change. This paper presents a general overview of property rights in natural resources, with particular reference to water and land and emphasizing that rights are what a society is willing to grant and enforce. If companies, individuals, groups, or the state are not managing and stewarding resources in sustainable ways, their authority should be challenged. Rights are social inventions, and society can abrogate them.Right of property--Canada, Right of property--United States, Natural resources--Canada--Management, Natural resources--United States--Management, Natural resources--Social aspects--North America, Tenure systems--North America, Resource /Energy Economics and Policy,
