The National Forests of the United States encompass 192.7 million acres (78 million hectares) of land, which is nearly five percent of the total land area of the nation. These lands are managed by the US Forest Service (USFS) for multiple uses, including extraction of timber, production of...

Economic analysts have expressed significant interest in the transition of the industrial base towards knowledge-intensive production. A central aspect of this transition is the growth and development of industries that provide the technological and scientific foundations for what is often...

Consider a stockpile consisting of n items where the ith item has a rating r_i, i = 1, ..., n. An item with rating r, if kept in stockpile until time t and then released to the field, will have a field life of rd(t). Thus it is assumed that for any t, the field life for issuance at time t is...

Interviews with fieldworkers from the UK 2001 Census give voice to a unique, grounded view of the operational quality of census-taking. While the overall response to the census has been estimated at 94%, enumerators and their managers explain why differential undercount between social and...

Regional economies are continually undergoing adjustment as their firm populations react to changing tastes, technologies, and the challenges of outside competition. Adjustment typically takes place as the stock of jobs is renewed in each industry. This micro-dynamic process of renewal has a...

The future of global environmental sustainability is contingent upon educating the next generation of environmental stewards. Critical elements of training such an interdisciplinary workforce include mentoring and experiential learning in the areas of science, communication, and leadership. To...

The Dearfield Dream Project is a collaborative research initiative to conduct historical, cultural, archaeological, and environmental studies on the early 20th Century African-American colony site of Dearfield, Colorado, USA. Because the breadth and significance of the Dearfield Project requires...

We obtain the moment structure of a general class of random variables generated by a Poisson process. We then apply these relationships to several applied probability models. Among these are queues, counter models and low density traffic flow.

A previous paper discussed explicit bounds in the exponential approximation for the distribution of the waiting time until a stationary reversible Markov chain first enters a 'rare' subset of states. In this paper Stein's method is used to get explicit (but complicated) bounds on the Poisson...
