We examine the status of the world's fisheries and the potential for economic and ecological benefits from fishery management reforms. Global fisheries are at a crossroads - they are on average overexploited, suggesting a global benefit from recovery. But many fisheries are already biologically sustainable. Even in these fisheries, economic...
In this paper, we use a common renewable resource model with stochastic growth to obtain three main results. First, we demonstrate that predictions of poor future environmental conditions lead to lower desired escapement (i.e., low remaining resource stock in place after harvest) and higher current harvest. At first glance, it...
Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of...
The COVID-19 pandemic became the deadliest epidemic since the Influenza pandemic in the early 1900s. (Centers for Disease Control and Prevention, 2023). Every government level across the United States had differing responses to COVID-19, and politicians have been the center of attention for their role in COVID policy support or...
Fast, reliable internet access is shown to have numerous economic benefits, including contributing to growth, increasing GDP, decreasing unemployment and depopulation of rural areas, and encouraging competition. However, in the United States, there are large sections of the population that are left severely underserved – mostly rural, low-income, and minority...
Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....
An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...

Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...
