The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the University of Washington C-131A aircraft during the Monterey Area Ship Track (MAST) experiment in 1994. During...
Although many fisheries around the world have long required explicit licensing for fishery participants, the use of limited entry licensing to control fishing effort has become a common practice in the last two decades. In contrast to Individual Fishing Quotas (IFQs), limited entry is only a step towards rights-based management....
Until now the topic of motion estimation, as used in video compression, has been dominated by search methodologies which are modifications of an exhaustive search. This research takes a completely new approach by applying two evolvable search algorithms, the Genetic Algorithm and the Genetic Program, to the area of motion...
This paper analyzes spatial patterns of exploitation in the California sea urchin fishery using two different econometric approaches: a Poisson/SUR model of monthly observations and a micro-level Nested Logit model of individual harvester daily decisions. Each model is used to simulate the spatial distribution of fishing effort. The models are...
This thesis is a study of Herman Melville’s symbolism. I have chosen to investigate the elemental images of water, fire, and stone in Moby-Dick (1851), Pierre; Or, The Ambiguities (1852), and Clarel; A Poem and Pilgrimage in the Holy Land (1876). This work is a semiotic study, insofar as the...
This paper proposes a two-stage method to estimate a generalized Gordon-Schaefer model,
using heterogeneous fishing data in the logbook. A Cobb-Douglas production function is consistently
estimated in the first stage by means of the ‘within period estimator’. A stock index
is constructed and used to estimate the logistic growth model...
Economists have long promoted fishery rationalization programs, but ITQs may fail to address the
ecological consequences of fishing. Of particular concern is that economic incentives to harvest larger
fish (due to size-dependent pricing or quota-induced discarding) can destabilize fish populations or lead to
evolutionary changes. A substantial theoretical literature in...
This paper analyzes optimal fishery management in the presence of an endangered predator that competes with humans for a commercially viable prey. Because traditional predator controls are not possible when the predator is endangered, we focus on harvest effort controls over the prey’s habitat as a means to maintain the...
Interest in sustainable fishing communities suggests the need to understand fishermen’s decisions about where to land fish. In this paper, we apply techniques used extensively to analyze fishing location choices to study landings location choices. We analyze detailed microdata from Norwegian groundfish vessels that land fish in fourteen different ports...
In marine resource management, spatial policy instruments, including Marine Protected Areas, are becoming increasingly important. The economic motivation for spatially explicit policy is that renewable resources generate, in addition to the conventionally recognized incentives to over-harvest in the face of insecure property rights, spatial externalities that distort the spatial distribution...
