The reduction and analysis of data from the low-frequency radio astronomy experiment aboard the OGO-4 spacecraft Final report
Reduction and analysis of data on low frequency brightness temperature of sky from OGO-4 radio astronomy experimen
Thermocouple installation
A thermocouple assembly which includes a plug having a pair of small diameter holes near one end thereof which are spaced a small distance apart to leave a thin quantity of plug material between the holes is presented. There are a pair of thermocouple wires extending through the different holes and with the outer ends of the wires joined to the thin quantity of plug material which lies between the holes to form a thermocouple junction
Re-examining the Consumption-Wealth Relationship: The Role of Model Uncertainty
This paper discusses the consumption-wealth relationship. Following the recent influential work of Lettau and Ludvigson [e.g. Lettau and Ludvigson (2001), (2004)], we use data on consumption, assets and labor income and a vector error correction framework. Key findings of their work are that consumption does respond to permanent changes in wealth in the expected manner, but that most changes in wealth are transitory and have no effect on consumption. We investigate the robustness of these results to model uncertainty and argue for the use of Bayesian model averaging. We find that there is model uncertainty with regards to the number of cointegrating vectors, the form of deterministic components, lag length and whether the cointegrating residuals affect consumption and income directly. Whether this uncertainty has important empirical implications depends on the researcher's attitude towards the economic theory used by Lettau and Ludvigson. If we work with their model, our findings are very similar to theirs. However, if we work with a broader set of models and let the data speak, we obtain somewhat different results. In the latter case, we find that the exact magnitude of the role of permanent shocks is hard to estimate precisely. Thus, although some support exists for the view that their role is small, we cannot rule out the possibility that they have a substantive role to play.wealth effect; vector error correction model; Bayesian model averaging; cointegration; variance decomposition.
Drug Cartels and the International Organization of Drug Trafficking in the 21st Century
This research is a brief overview of the new cartels emerging to dominate today\u27s international traffic in drugs. In terms of geographic reach, economic impact, and imperiousness to law enforcemnt, drug cartels became the dominant form of organized crime in the last two decades of the 20th century. In the 21st century drug cartels have taken advatage of the massive increases in international trade and commerce and have learned from the mistakes of the earlier cartels. The new cartels are more numerous, flexible, chameleonic in their nature, and durable than any we have seen before

The Antecedents of Organized Criminality in Kentucky
This Kentucky Justice & Safety Research Bulletin examines the antecedents of modern-day organized crime in Kentucky. The question to be addressed is whether the genesis of organized crime in a predominately rural, southern state, such as Kentucky, follows well-established patterns of development found in historically analyses of Chicago, Philadelphia, New York, and other north-eastern and midwestern locales. This question is addressed by an examination of primary and secondary historical data sources relevant to early forms of organized crime. The research concludes that while Kentucky exhibited strikingly different forms of economic, socal and political organization compared to northeastern and midwestern locales, the genesis of criminal organizations was much the same
