The survival of biochemical information in archaeological bone

The paper gives a review of the advantages of genetic information potentially available from surviving molecules (especially proteins) in bone. Survival of such information depends on degradative processes during burial. Conventional protein chemical and immunochemical investigations on various organic components remaining in buried archaeological bone are described. The results provide information on the chemistry of collagen degradation, and indicate that polymorphic macromolecules survive at too low a concentration to be easily detectable.     

Managing the Solid Waste Crisis

Policymakers at all levels of government now face the difficult task of siting new waste facilities in the face of public apprehension and opposition. This study offers a causal model to evaluate the potential of operation and economic incentives for mitigating siting opposition while controlling for background characteristics and environmental attitudes. Among those incentives evaluated, local committee oversight, property tax credit, and money for schools proved to be the most useful options for tempering opposition among citizens.     

Rethinking Easter Island's ecological catastrophe

Rapa Nui (Easter Island) has become a paragon for prehistoric human induced ecological catastrophe and cultural collapse. A popular narrative recounts an obsession for monumental statuary that led to the island's ecological devastation and the collapse of the ancient civilization. Scholars offer this story as a parable of today's global environmental problems. In this paper, I review new and emerging Rapa Nui evidence, compare ecological and recently acquired palaeo-environmental data from the Hawaiian and other Pacific Islands, and offer some perspectives for the island's prehistoric ecological transformation and its consequences. The evidence points to a complex historical ecology for the island; one best explained by a synergy of impacts, particularly the devastating effects of introduced rats (Rattus exulans). This perspective questions the simplistic notion of reckless over-exploitation by prehistoric Polynesians and points to the need for additional research.     

Studying Public Policy through Immigration Policy: Advances in Theory and Measurement

This essay provides a critical review of the field of immigration policy studies from the perspective of measurement and modeling. It serves to contextualize and broaden the views presented in the special issue. As such, we combine insights from American and comparative politics, pinpoint key limitations and challenges in the field, and identify areas of strength within each subfield which could inform theory and measurement development for the other. Ultimately, the concerns about conceptualization, definition, and measurement that we identify and discuss herein, do not apply only to immigration policy studies but to policy studies writ large.     

PLAGUE AND POWER RELATIONS

Public policy and economic practice, quintessential expressions of institutional cognition, create an opportunity structure constituting a tunable, highly patterned,‘non‐white noise’ in a generalized epidemiological stochastic resonance that can efficiently amplify unhealthy living and working conditions, particularly within highly concentrated, marginalized urban populations, to evoke infectious disease outbreaks. This is especially true for the infections carried by socially generated ‘risk behaviours’ which are usually adaptations to histories of resource deprivation or marginalization. A number of local epidemics originating in such ecological keystone communities may subsequently undergo a policy and structure‐driven phase transition to become a coherent pandemic, a spreading plague which can entrain more affluent populations into the disease ecology of marginalization. We use this approach to contrast the ecological resilience of apartheid and egalitarian social systems, and apply these perspectives to the forthcoming social and geographical diffusion of multiple drug resistant (MDR) HIV from present AIDS epicentres to the rest of the United States.
