I believe quetzal and aguacatillo are the key species in the cloud forests in Cerro de la Muerte because they are biologically and culturally valuable. This value contributes to ecotourism, which eventually becomes of economic benefit to local people. In this paper, I examine how the cloud forest conservation and...
We studied the effect of a lactic acid bacterial additive on the quality of silage made of grass-legume mixtures in the forest steppe zone of Mongolia. The use of lactic acid bacterial ferment positively influenced the diet digestion and the cows silage consumption. The cows ate well the silage treated...
We assessed a photographic technique to estimate shrub yield and utilization of common snowberry, snowbrush, and heart-leafed willow found in mixed-conifer rangelands. We determined the correlation between green leaf area size (LA) and forage yield (Y) and compared plant utilization estimated by photographic technique (ULA) to actual utilization (UY) values....
The Department of Administrative Services (DAS) and Oregon State University (OSU) are collaborating to develop an orthoimagery portal application to allow for the distribution of digital aerial imagery for the State of Oregon. The near-term objective of this project is to develop an Imagery Portal that serves the
2005 half-meter...
Although researchers have begun to explicitly support end-user programmers' debugging by providing information to help them find bugs, there is little research addressing the right content to communicate to these users. The specific semantic content of these debugging communications matters because, if the users are not actually seeking the information...
ExcelForms is a front end Excel-based application that supports Forms/3, a research
language based on the spreadsheet paradigm, end-user software engineering features.
The old implementation of ExcelForms performed poorly, and was considered
unstable, not robust, and not scalable enough for our users' needs. This project
addresses these issues by implementing...
This paper studies cluster ensembles for high dimensional data clustering. We examine three different approaches to constructing cluster ensembles. To address high dimensionality, we focus on ensemble construction methods that build on two popular dimension reduction techniques, random projection and principal component analysis (PCA). We present evidence showing that ensembles...
If basic assumptions about how knowledge workers conceptualize and use work units are wrong, then any solutions resting on those assumptions are unlikely to be successful since, instead of decreasing costs, they will lead to increasing them. This paper reports on how knowledge workers understand, use and switch between units...
Summary: Four proposed metrics:
[1] average relative reduction in training time (sample size, number of training experiences)
[2] jumpstart (initial advantage of transfer algorithm)
[3] handicap (how long it takes the no-transfer algorithm to overcome the jumpstart)
[4] asymptotic advantage (how much better the transfer learning algorithm does in the...
The security of world fish supply from wild fisheries and from aquaculture is an increasing concern due to dwindling yields from wild catch and undesirable ecological impacts of aquaculture. The extent to which aquaculture can substitute for fish from wild catch will depend on the productivity of aquaculture, which in...
The geoduck fishery in British Columbia has been managed by individual quotas since 1989. Individual
quotas have fostered a co-operative management approach in the fishery, which is implemented through a
non-profit society with membership made up of licence holders in the fishery. This non-profit society, the
Underwater Harvesters Association (UHA),...
Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish
population-dynamics and production, coupled with an aquaculture production model, to investigate
effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying
capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....
This paper sets out an evaluation of profitability differentials within shellfish farming activities of the
Mont-Saint-Michel Bay. The objective is to examine whether profitability differentials have
consequences in terms of economic dynamics and of management arrangements. The paper divides into
four parts. The first part presents a retrospective analysis of...
The advent of scientific shrimp farming in India during 1990-91 was a turning point of shrimp production
in the country. Though scientific shrimp farming system renders higher level of production than the
existing traditional farming system, it is subject to certain criticisms especially for generating negative
environmental externalities. The conversion...
The exploitation of aquatic food products has been very fundamental as a source of livelihood in
the Sub Saharan Africa in particular and the world in general. Global production of aquatic food
products totaled approximately 93.2 million metric tons in 1997 and sub Saharan Africa
contributed 3.7 per cent. For...
In natural resource economics, we sometimes observe a situation in which producers and consumers have
direct access to the factors of production or can use some consumable products with little or no
transformation. These goods are commonly referred to as “gifts of nature”. A factor of production is
considered a...
