Municipal Solid Waste Flow Control in the Post-Carbone World

Garbage will always ultimately be the government\u27s problem. Evolving environmental standards and state and federal policies will continue to require reasoned responses from local governments and municipal solid waste flow control is a vital cog in many jurisdictions\u27 solid waste management solutions. Without flow control of some form, governments\u27 ability to plan and provide for the most environmentally sound and economically acceptable solutions will wane, leaving the public vulnerable to the vagaries of a private market that does not have a duty to protect the public health and safety. The Carbone decision has blunted one of the local governments chief weapons-legislative flow control-and it appears Congress will not supply an adequate answer for many solid waste systems. More than ever, alternatives to legislative flow control will be needed to enable municipalities to fulfill their solid waste duties, to comply with federal and state mandates, and to provide workable, environmentally-sound, long-term solid waste programs serving the interests of the public health and safety. Local governments must act soon by examining these options and deciding which will best serve the public

CONTROL OF NONPOINT SOURCE POLLUTION THROUGH VOLUNTARY INCENTIVE-BASED POLICIES: AN APPLICATION TO NITRATE CONTAMINATION IN NEW YORK

A voluntary program is developed to achieve environmental goals through the self-interested choices of farmers under environmental risk and asymmetric information. Farmers behave to maximize expected net returns, and environmental quality standards are formulated through chance constraints. Because the government may not know each farmer's soil type, policy options must be self-selecting. The model is applied empirically to nitrate leaching and runoff from corn production in three New York regions. Asymmetric information between producers and the government would impose additional cost burdens on society, but these costs are modest in the context of other farm programs.Environmental Economics and Policy,

OPTIMAL LAND CONVERSION AT THE RURAL-URBAN FRINGE WITH POSITIVE AND NEGATIVE AGRICULTURAL EXTERNALITIES

Bid-rent curves are incorporated in a stochastic dynamic programming model of land development around a city when farmland generates both positive and negative externalities. The model delineates how the quantities of land in various uses over time should depend on the relative social weights assigned to the competing agricultural externalities.Land Economics/Use,

Evaluation of the Strecker synthesis as a source of amino acids on carbonaceous chondrites

The Strecker synthesis (SS) has been proposed as the source of amino acids (AA) formed during aqueous alteration of carbonaceous chondrites. It is postulated that the aldehyde and ketone precursors of the meteoritic AA originated in interstellar syntheses and accreted on the meteorite parent body along with other reactant species in cometesimal ices. The SS has been run with formaldehyde, acetyldehyde, propionaldehyde, acetone, and methyl ketone as starting materials. To study the effect of minerals on the reaction, the SS was run in the presence and absence of dust from the Allende meteorite using deuterated aldehydes and ketones as starting materials. The products were studied by GC/MS. With the exception of glycine, the retention of deuterium in the AA was greater than 90 pct. Some D exchange with water does occur, however, and determination of the rate of exchange as a function of pH and temperature may allow some bounds to be placed on the duration of parent body aqueous alteration. The retention of D by the AA under conditions studied thus far is consistent with the model that a SS starting from interstellar aldehydes and ketones led to the production of meteoritic AA

Delineation of the boundaries of a buried pre-glacial valley with LANDSAT-1 data

The continuity of a narrow meandering strip of Udoll (prairie) soils running east and west for approximately 40 miles across north central Indiana in an area predominantly of Udalfs (timber soils) was detected from LANDSAT-1 data taken on June 9, 1973. This data was processed through a clustering procedure and classified with resulting increased definition of the boundaries among soils grouped according to nine categories and vegetation to two categories of reflectance. This dark stretch of prairie soil is believed to have formed in the heavy textured, poorly drained glacial debris which filled a major pre-glacial tributary of the Teays River System. Ready identification and location of the valley has significance to soil survey and land classification people as a guide to soil classification and land use and to geologists as a guide to location of a potentially economically significant aquifer

Avatars:the other side of Proteus's mirror : a study into avatar choice regarding perception

The trend for online interactions, can be regarded as being ‘anti-so-cially social’, meaning that a great deal of time is spent playing, working and socializing with the internet serving as the communication conduit. Within that Virtual Social Environment very deep relationships are formed and maintained without the parties ever having met each other face-to-face. Raising the question how much does the physical appearance of an avatar influence the perception of the person behind it? Are relationships informed by appearance even in the vir-tual world and what implications does that have for second language acquisition? This paper leads to a small-scale research project where a selection of avatars with various racially identifiable characteristics were used to identify which av-atars a second language speaker would feel more at ease interacting with in the target language. The resultant research aims to test three hypotheses regarding preferred avatar choice for second language users based solely on perceptions

Investigating the Role of Bptf in Immunoediting in Breast Cancer and Melanoma

In this study, we explore the effects of NURF depletion on the growth of tumors in immune-competent mice. NURF depletion in tumors results in reduced tumor growth in immune-competent mice, suggesting enhanced anti-tumor immunity. Analysis of the tumor microenvironment by flow cytometry revealed a significantly elevated CD8 and progressively elevated activated CD8 phenotype in Bptf KD tumors, possibly contributing to the increase in cell death and decrease in tumor weight observed. Examination of antigen presentation was evaluated using the OT-1 and Pmel-17 models, though no significant difference in cytotoxicity was observed as measured by LDH and/or IFNγ assays. This indicates possible novel antigen presentation mechanisms in tumor cells, and not increased presentation of existing antigens, contributes to the decreased tumor weight observed in Bptf KD tumors
