The central issues with which this study is concerned revolve around the major determinants of agricultural export instability in Nigeria. Specifically, the study examined the relationship between oil export and the agricultural export performance in Nigeria. In trying to achieve this objective, an ordinary least square multiple regression approach was adopted for the data analysis. Some statis...

Is the stock market boom a result of the baby boom? This paper develops an overlapping generations model in which a baby boom is modeled as a high realization of a random birth rate, and the price of capital is determined endogenously by a convex cost of adjustment. A baby boom increases national saving and investment and thus causes an increase in the price of capital. The price of capital is ...

Abstract. We present Boom, a comprehensive analysis tool for Boolean programs. We focus in this paper on model-checking non-recursive concurrent programs. Boom implements a recent variant of counter abstraction, where thread counters are used in a program-context aware way. While designed for bounded counters, this method also integrates well with the Karp-Miller tree construction for vector ad...

Child food security is a longstanding concern to policymakers, exacerbated by economic slack and instability. We use the fracking era oil gas boom of early 2000s as natural experiment examine importance state conditions for child security. The was large unexpected shock that substantially improved labor market in states with resources but not elsewhere. find increases income improve security, e...

During 2003-2013, the U.S. oil and gas extraction industry experienced unprecedented growth, doubling the size of its workforce and increasing the number of drilling rigs by 71%. To describe fatal events among oil and gas workers during this period, CDC analyzed data from the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI), a comprehensive database of fatal work in...

According to the existing problems in the development of actual product and working process of excavator working device’s boom, the method of integrated design and analysis for excavator boom is put forward. The defects in the process of CAD/CAE integration are summarized, the integrated design and analysis system including parametric design of boom, database design, detail feature simplificati...

Boom clay has been selected as a potential host rock formation for the geological disposal of radioactive waste in Belgium. In the present work, the hydro-mechanical behaviour of Boom clay samples from the borehole Essen-1 at a depth of 220-260 m and from HADES that is the underground rock laboratory at Mol in Belgium, at 223-m depth was investigated in the laboratory by performing low pressure...
