In finance dynamic stochastic programming traditionally has been applied to institutional pension fund problems and more recently has become usable for more difficult individual wealth management problems. We develop several models to handle specific wealth management issues. We develop a US investment model with an exact tax basis and a rudimentary tax qualified portfolio. We show the ability to solve this model with up to 48 stages in 10 asset classes using an exact tax basis by approximating the solution employing information constraints. For fewer stages we show tractability of solving the

Marine Protected Areas (MPAs), the Ecosystem Approach to Fisheries management (EAF) and Integrated Coastal Management (ICM) have been identified as possible alternatives to traditional linefish management measures, which have largely failed. Monitoring and assessment of fish communities on a long-term basis is necessary, and will provide a means to evaluate the effectiveness of such management measures. Therefore, standardised protocols and optimal sampling methods for long-term monitoring (LTM) and assessment of coastal fish communities are essential. This study aimed to identify suitable met

Sampling methods used for the assessment of exposure to volatile organic chemicals (VOCs) in the workplace or for environmental studies are now limited to an upper integrative sampling time of 24 hours or less. Generally, these methods lack versatility and are difficult to use. A passive sampler that can extend sampling periods was developed as part of this research. This novel sampler relies on capillary tubes to restrict and control ambient air entry into an evacuated sample container.<br>A mathematical model was derived by modifications to the Hagen-Poiseuille and ideal gas laws.

For the construction of a wind farm, one needs to assess the wind resources of the considered site location. Using reference time series from numerical weather prediction models, global assimilation databases or observations close to the area considered, the on-site measured wind speeds and wind directions are corrected in order to represent the actual long-term wind conditions. This long-term correction (LTC) is in the typical case performed by making use of the linear regression within the Measure-Correlate-Predict (MCP) method. This method and two other methods, Sector-Bin (SB) and Syntheti

The National Ecological Observatory Network (NEON) will monitor ground beetle populations across a network of broadly distributed sites because beetles are prevalent in food webs, are sensitive to abiotic factors, and have an established role as indicator species of habitat and climatic shifts. We describe the design of ground beetle population sampling in the context of NEON's long-term, continentalscale monitoring program, emphasizing the sampling design, priorities, and collection methods. Freely available NEON ground beetle data and associated field and laboratory samples will increase sci

Termites are considered to be major ecosystem engineers in tropical and sub-tropical environments, and fire in savanna systems is regarded as a major and necessary disturbance for the maintenance of biodiversity. However, most fire ecology studies have focused on vegetation dynamics with little attention given to other taxa, especially invertebrates. This thesis has addressed several aspects of savanna termite ecology. First, based on a review of studies examining the relationship between fire ecology and termites, I found that few broad conclusions can be made based on the published literatur

There is increasing public concern about the health of our environment and the burden placed on it by the way the world uses its natural resources. This requires decisions be made about the best manner to care for these resources. To make these decisions, long term ecological monitoring efforts are necessary as they provide decision makers with accurate information concerning the status of measures in time. The planning of such efforts is a study of decision making in itself. This thesis has considered ways in which those responsible for the planning of long term ecological monitoring survey

Tsitsikamma National Park (TNP) possesses the oldest (established 1954), and one of the largest (350 km2) ‘no-take’ marine protected areas (MPA) in South Africa. A long-term monitoring (LTM) programme to observe the subtidal reef fishes in the TNP MPA was established in 2007. To date, 243 angling replicates have been completed, and a total of 2,751 fish belonging to 41 different species have been caught and released. In an era of unprecedented global biodiversity loss, data that can be used to monitor ecosystems and gauge changes in biodiversity through time are essential. This thesis aims to

Conserver les espèces pollinisatrices est un enjeu majeur, notamment en milieu agricole où elles sont indispensables à la pollinisation de différentes cultures. Ici, nous avons décidé de caractériser ces espèces et leurs ressources florales dans une plaine céréalière intensive, à travers l’utilisation de plusieurs années de données acquises grâce à plusieurs protocoles d’échantillonnage. Cette plaine se caractérise par une forte dynamique spatio-temporelle, résultant des floraisons massives mais brèves des cultures oléagineuses.

This Master’s research program was undertaken as part of the Hakai Ancient Landscapes Archaeology Project in Heiltsuk and Wuikinuxv Territories on the Central Pacific Coast of British Columbia (BC), Canada. The project tested the utility of applying vibracore technology to sample a shell midden site on Hecate Island on the BC Central Coast. This revealed that the earliest archaeological occupation began approximately 6,000 years ago, continuing into the 16th Century AD. Analysis using 21 radiocarbon dates from six core samples shows the site was repeatedly occupied and accumulated consistently

Indiana University-Purdue University Indianapolis (IUPUI)<br>Mercury (Hg) has proven to be a risk to the public, mainly through the consumption of fish. Because of this, many fish consumption advisories have been issued in Indiana. Although much is known about the global cycle of mercury, little is known about how local and regional emission sources of mercury impact local and regional mercury cycling. This study’s objective was to determine the scope of mercury concentration in central Indiana by using a broad grid of soil mercury measurements. Sampling was designed to capture the net retaine

The Polar regions are considered to be particularly susceptible to the effects of climate change. Although there is evidence for warming in the Antarctic during the last century, few long-term ecological monitoring programmes have been initiated in this region. Zooplankton have been demonstrated to be excellent environmental indicators and in 1991 a Continuous Plankton Recorder (CPR) survey was established in the Southern Ocean south of Australia for monitoring purposes. Using data collected between October 2001 and March 2002 this thesis aimed to provide baseline data for the Southern Ocean C

Common strategies used in nursing homes to improve quality of care for residents are integration of person-centered care and assessing care using satisfaction surveys. Although approaches of integrating person-centered care and satisfaction surveys have been valuable in improving nursing home quality, strategies of care that include things that matter from residents’ perspectives while living in nursing homes need investigation.
