This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...
If wind power is to become a viable energy alternative, a rapid and reliable cost effective methodology must be established, whereby large areas can be surveyed for windy sites and those sites can be evaluated. Based primarily on locating wind deformed vegetation, this paper establishes the feasibility of using air...
Aerial videography in combination with GPS were used to monitor the
active surge of Alaska's Bering Glacier. The large aerial extent of the study area and the
unpredictable weather in coastal Alaska required innovative techniques to be used in
order to successfully monitor the surge environment. A portable aerial videographic...
The semantic differential technique was used to
quantify four interest groups' perceptions of twenty-six
Alaskan scenes. The scenes represented both panoramic views
and views of Mount McKinley from different sites in southcentral
Alaska. The perceptions were measured on six semantic
scales ("ugly-beautiful", "dislike-like", "unpleasantpleasant",
"unstimulating-stimulating", "level-mountainous",
and 'monotonous-varied"), and the...
Small-scale fisheries are no exceptions to the requirements of staying within the biological bounds of sustainability, by purposively limiting fish harvests, and of maintaining productivity of oceans and freshwater systems, by protecting ecosystem health and habitat quality. However, while these fisheries, like all others, have the potential to pose conservation...
Climate change will have a wide range of impacts on fisheries, other human uses of marine systems, and the coastal communities that depend on the ocean for their livelihoods. This presentation focuses on small-scale fisheries, providing a review of the current state of knowledge on social and economic impacts of...
This paper explores how the implementation of appropriate policy measures and underlying institutions can support sustainability and resilience in fishery systems. The policies discussed fall into three categories. First are those relating directly to fishery management, including the development of a management portfolio, application of the precautionary approach, and implementation...
Community fishery rights are use rights (the right to take part in fishing) and/or management rights (the right to be involved in managing the fishery) implemented at a local, community level. While by no means a new invention, community rights are receiving renewed attention as a mechanism to improve the...
Subsidies are most often discussed within global fora (such as the World Trade Organization) in terms of concerns over trade distortions, if some countries gain an unfair advantage, through their subsidies, over unsubsidized industry elsewhere. In fisheries, this concern is matched by an environmental argument – that fish stock depletion...
To effectively respond to sustainability challenges, there is a need to find (or re-discover) suitable ways to govern, so as to make decisions that maintain healthy environments and sustainable livelihoods in fishery systems. While efforts to this end are needed at all governance levels, from the global to the local,...
There is increasing recognition that the oceans of the world support a wide range of economic sectors. Managing those multiple uses, within a ‘commons’ environment, is undoubtedly challenging. Approaches of ecosystem-based management (EBM), integrated ocean management (IOM) and marine spatial planning (MSP), with associated aspects of spatial allocation and conflict...
This paper provides an overview of use rights, that sanction fishers, fisher groups and fishing communities to access and use fishery resources. The paper first reviews the various forms of use rights, ranging from access rights (territorial use rights and limited entry) to quantitative input (effort) and output (harvest) rights....
Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...
The vascular endothelium is a single cell layer that lines the lumen of the entire vasculature. It is the site of synthesis of nitric oxide (NO), a vasodilatory compound synthesized by endothelial nitric oxide synthase (eNOS). NO causes intracellular calcium sequestration of the vascular smooth muscle cells, relaxing and dilating...
The treatment of certain types of cancers brings with it serious physiological and
psychological side effects in cancer survivors, including: decreased aerobic capacity,
muscle wasting, body composition changes, fatigue, and a diminished overall quality of
life. Exercise may directly influence the physiological side effects of cancer and cancer
treatment, and...
The purpose of this study was to develop a profile
of Christian College physical education faculty members
regarding their academic preparation, professional
experience, and selected duties, as well as to identify
important components of graduate preparation at the
doctoral level for future faculty at these
institutions.
A survey instrument was...
