develop a Bayesian Network (BN) to assess priorities for restoration of aquatic...
The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...
The individual size of fish as a proxy for life-history traits and market
value displays an important, yet in bioeconomic modelling often ignored
biological and economic parameter. This raises the question if and to what
extent the consideration of a pricing related to the individual size
influences optimal harvest strategies....

We tracked three groups of steelhead Oncorhynchus mykiss smolts implanted with acoustic transmitters to determine whether the degree of hatchery domestication or the juvenile rearing environment (hatchery raceway versus natural stream) influenced migration timing and survival in the Alsea River and estuary, Oregon. Two groups consisted of age-1 smolts reared...
Qualitative data analysis (QDA) is a time consuming and, potentially unreliable research activity. In qualitative research, a number of tasks must be repeated for every new research case, even if each case is closely related or is in the same area of study.
Existing QDA applications provide users with a...
Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...
In this thesis, I discuss the uses of two different forms of young adult novels for relaying messages about adolescence and femininity to adolescents from adult authors. I explore the traditional and organized quest narrative as written by Anne McCaffrey in her Harper Hall Trilogy with a young female hero....
Global climate change is projected to have far-ranging effects on the oceans and
marine life. In turn, fisheries will likely undergo changes in their distributions and
abundance. Coastal Alaskan communities are often highly dependent on commercial
fisheries, and as a result will likely be vulnerable to climate change. The purpose...
This project defined criteria to allow only the use of existing spatial databases (and only those with comprehensive coverage of the ecoregion) to identify the HGM (hydrogeomorphic) class of mapped Willamette Ecoregion wetlands. The project then applied those criteria automatically and systematically to every mapped wetland in the ecoregion, resulting...
To achieve a goal of “no net loss” of wetland functions as well as acreage, it is important to know which functions wetlands in a specific region or watershed may individually provide, at what level. Although methods exist for assessing functions of Oregon wetlands (ORWAP; Adamus et al. 2009), site...
This article discusses findings from a longitudinal research study that examined the way graduate students carry out the literature review and how they were impacted by attending a library literature review workshop. The literature review research process serves as an important gateway for graduate students’ into their scholarly communities’ practices,...
Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

shown these organizations need a simple, flexible process with stakeholder participation
to measure...
Recreational fishermen quickly adjust fishing effort directed at a specific
site to variations in fishing quality. Holding all other quality parameters
constant, the functional relationship between fish abundance and the
resulting recreational fishing effort is denoted an effort response function.
This paper proposes a Cobb-Douglas utility function for the benefits...
Recent work in the domain of fisheries ecology has shown that major
changes occur in fish communities exploited by commercial fisheries.
Selective fishing pressure on the more highly valued components of fish
communities is amongst the key factors proposed to explain these changes.
Under de facto open access conditions, it...
The generation mechanism for downslope windstorms was shown to vary according to inversion height and strength using a series of numerical experiments. Strong low level inversions were dominated by interfacial waves on the inversion, while high level inversion and cases without an inversion were dominated by internal gravity wave (IGW)...
Kenyan women exhibit a pattern of unequal access and participation to education, particularly Science, Mathematics and Technology (SMT) subjects and careers. This is the result of documented challenges that include cultural attitudes that overburden girls with chores to the detriment of their school work, and a preference by parents to...
Researchers around the world use various solution-based deposition techniques to deposit thin films with multiple layers that typically require multiple rounds of deposition. Some such techniques include successive ionic layer adsorption and reaction (SILAR), and layer-by-layer (LBL) deposition.
One of the main issues with deposition of these types of films...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
There is a consensus in the scientific community that overexploitation of most fisheries worldwide has had significant negative effects on coastal marine ecosystems, and the majority of assessed fish stocks still require rebuilding programs. Almost all of the scientific studies conducted in recent decades have focused primarily on analysis related...
The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water.

Interest in ecosystem-based management or the ecosystem-based approach
to fisheries management has rapidly increased on a global basis. Most
options for ecosystem-based management have emphasized some type of
biological and natural conservation or non-use, and minimal attention has
been given to assessing the social and economic ramifications of
ecosystem-based management....
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Throughout the Indo-Pacific region, communities are increasingly
empowered with the ability and responsibility of working with national
governments to make decisions about their marine resources. In some
instances, co-management arrangements have been successful at
conserving marine resources by developing locally appropriate rules to
limit overexploitation. These examples have often prompted...
The Universal Declaration of Human Rights establishes the right to clean water, entitling everyone to “sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses”. This rationale is the inspiration for comparing the effects of clean water strategies. A comparison between Tunisian and Egyptian approaches will evaluate...
The aquaculture sector is uniquely placed to complement production from the stagnating capture fisheries sector and it has advantages in terms of controllable production characteristics. However, aquaculture poses undeniable economic, environmental and social challenges that may be poorly evaluated or inadequately addressed within current policy frameworks. In such cases, the...
Combinations of 7 remarkably similar factors have led to the (partial)
failure of recent efforts to address five global or national crises. The paper

crisis, the blue fin tuna collapse in the Atlantic Ocean and the collapse of
fish...
In 1996, the US New England Fishery Management Council formed a
technical team (PDT) to develop a new plan for Atlantic Herring (Clupea
harengus harengus). The inshore stock was close to fully exploited while
the offshore stock was underexploited. There were few full-time herring
harvesters and very few processors. Fresh...
The Willamette River floodplain has been highly modified by urbanization, conversion of land to agriculture, construction of dams and revetments, and regulation of flow, all of which have reduced floodplain processes that provide valuable ecosystem services such as fish and wildlife habitat and flood storage. Efforts to protect and restore...
Indian Ocean Tuna fisheries after a rapid development period from
seventies to the end of the last century are faced with challenges including:
the fishing capacity control, the profitability improvement, and the
limitation of impacts on high seas biodiversity. In this area, tuna species
are exploited by coastal states as...
To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United
Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations
to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when
the cooperative coalition of countries acts...
Marine scientists and stakeholders are increasingly advocating ecosystembased
fishery management (EBFM). However, the way to operationalize
such EBFM remains controversial. The viability approach can be a relevant
modelling framework for EBFM as it accounts for dynamic complexities,
uncertainties, risks and sustainability objectives balancing ecological,
economic and social dimensions together with...
The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...
This essay provides a snapshot of major policy change in the siting of radioactive waste depository facilities in South Korea during 2005. After 20 years of failing to locate a radioactive waste depository facility, South Korea finally succeeded in locating a facility through a major policy change of delegating decision...
Vietnam’s policy is to shift the fishing pressure from onshore to offshore water since the coastal resource has been overexploited, and a programme for investing in offshore vessels has thus been implemented since 1997. The question raised is whether the offshore fishing fleet is profitable and efficient or not? This...
In most of the coastal countries, the fisheries enable to satisfy multiple socio-economic needs such as food safety, public receipts, employment and so on. It is especially true in many coastal developing countries where fisheries constitute a considerable source of food and incomes. However, the strong pressure on the fisheries...
40 years ago the Atlanto-Scandian herring stock collapsed with severe consequences for Iceland´s monotonic economy at that time. Two years ago the international credit crisis brought the country´s largest banks to insolvency, which shocked the whole economy with butterfly effects in neighbouring countries. The paper begins with an overview of...
For cell-like upper semicontinuous(usc) decompositions G of finite dimensional manifolds M, the decomposition space M/G turns out to be an ANR provided M/G is finite dimensional ([Dav07], page 129 ). Furthermore, if M/G is finite dimensional and has the
Disjoint Disks Property (DDP), then M/G is homeomorphic to M ([Dav07],...
Test taking is a humiliating experience for many students, with no perceived direct educational benefit. That need not be so. When circumstances allow, I use a two-pen method of collaborative testing. Students have told me that they leave the exam having figured out what they didn’t understand, filled in the...
The Critical Depth Hypothesis formalized by Sverdrup in 1953 posits that
vernal phytoplankton blooms occur when surface mixing shoals to a depth shallower than a
critical depth horizon defining the point where phytoplankton growth exceeds losses. This
hypothesis has since served as a cornerstone in plankton ecology and reflects the...
Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species.

The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...
Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The...
Worldwide, the scientific community and international organisations have
gradually agreed on the need for an ecosystem-based approach to fishery
management. However, the practical implementation of such an approach
faces huge problems, especially in developing countries where current
fishery management systems are generally weak.
