Some implications of increased cooperation in world oil conservation

In this article, Stephen Brown and Hillard Huntington combine recent studies of world oil markets and the nascent literature on damage estimates from carbon dioxide (CO2) emissions to derive cost and benefit curves for the reduction of these emissions through cooperative programs of oil conservation. Their analysis shows that the desirability of extending cooperation in global energy conservation policies is essentially an empirical issue rather than a conceptual one. The current evidence suggests that over the next two decades, the Organization for Economic Cooperation and Development will have an incentive to reduce its oil consumption and the associated CO2 emissions by more than is optimal from a world perspective. During this period, extending cooperation to the oil-importing developing countries may push oil conservation too far.Petroleum industry and trade

Coherent analysis of quantum optical sideband modes

We demonstrate a device that allows for the coherent analysis of a pair of optical frequency sidebands in an arbitrary basis. We show that our device is quantum noise limited and hence applications for this scheme may be found in discrete and continuous variable optical quantum information experiments.Comment: 3 pages, 3 figures, submitted to Optics Letter

An empirical study of ethnic linkages in Kenyan rural-urban migration

Regression analysis is used to explain rural-urban migration flows in Kenya as a function of economic incentives and the distribution of potential ethnic contacts linking urban and rural areas. These ethnic linkages not only have high explanatory power but also improve the performances of the other economic variables. The results indicate that migration is highly sensitive to the level of urban formal-sector wages but is not directed toward centres experiencing faster growths in formal-sector employment. It appears that when the urban labour- markets are expanding very slowly, ethnic contacts rather than urban jobs are a better indicator of the probability of obtaining urban employment

School Safety Manual for Bennett Elementary

This project examined preventative and responsive safety plans that improved the educational climate of schools through the successful elimination of negative physical, mental and emotional threats to students and employees. The review of current research found that schools were more successful in reducing or eliminating safety threats when a comprehensive school safety program was collaboratively developed and implemented Furthermore, a comprehensive school safety plan that was made easily accessible to every member of the staff and that was assessed continuously also played a vital role to the success of the school safety plan. Included is a comprehensive school safety manual that focused on providing staff, students and parents with. preventative and responsive methods for eliminating safety threats in the school. The manual used various forms of written expectations, safety procedures and preventative and proactive discipline interventions. The overall purpose of the manual was to ensure the academic and social success of students through maintaining a safe and positive school climate for students, staff and parents

Are there spurious temperature trends in the United States Climate Division database

The United States (U.S.) Climate Division data set is commonly used in applied climatic studies in the United States. The divisional averages are calculated by including all available stations within a division at any given time. The averages are therefore vulnerable to shifts in average station location or elevation over time, which may introduce spurious trends within these data. This paper examines temperature trends within the 15 climate divisions of New England, comparing the NCDC\u27s U.S. Divisional Data to the U.S. Historical Climate Network (USHCN) data. Correlation and multiple regression revealed that shifts in latitude, longitude, and elevation have affected the quality of the NCDC divisional data with respect to the USHCN. As a result, there may be issues with regard to their use in decadal- to century-scale climate change studies

Detailed design and construction of the St. Louis Park ice rink

The structure is the cover of a new ice skating rink, owned by the City of St. Louis Park, MN. It has a PTFE-coated fiberglass fabric roof, supported on glu-laminated timber arches. The cover is 73m x 41m in plan, and supported by eight parallel arches bearing on concrete piers(Figures 1-3). The roof has a plan area of approximately 2,500 m
