As an archipelago, the area was designated a protected area at the beginning of the 20th century, became a national park in 1993, and designated as a wetland of international importance in 1997. VNP faces many challenges including a decentralized management structure, disjointed conservation plan, and lack of a visitor management plan. The purpose of the CCC fellowship is to enhance VNP and stakeholder capacity to manage nature conservation collaboratively, enhance sustainable livelihoods among tour operators via tourism to the park and to enhance the visitor experience. Data have been gathered via an onsite survey among international visitors, two initial workshops with VNP stakeholders and a second home owner survey conducted in summer/fall 2012. The project links conservationists, tourism specialists, NGOs, INGOs (PAN Parks, WWF), local municipal governments, and universities (Kuresaare College) in a collaborative process for conservation and tourism development. This presentation will highlight key findings of the various phases of the project thus far as well as challenges posed due to ongoing institutional changes protected area agencies face in Estonia
Directing the Basic Communication Course: Eighteen Years Later
We focused on three problems that evolve over time for veteran basic course directors. After briefly commenting on the state of basic course literature, we discuss dealing with tradition, motivating students for the long term, and maintaining our own motivation for the course — three areas quite distinct from those addressed in an earlier article. The ideas and issues discussed here have arisen as a result of eighteen years of directing a basic communication course
Teaching Basic Courses: Problems and Solutions
Basic speech courses enroll many students. Basic course instructors are often under great pressure to succeed and to be effective. Because of the numbers of students and the pressures, they experience many problems. Five are discussed in this article: rigor versus leniency, independence versus dependence, theory versus skills, being close versus being distant, and objective evaluation versus subjective evaluation. Solutions to these problems are likely to affect both student and instructor motivation. Solutions are also likely to affect how students perceive instructors. That\u27s why, with respect to basic course instructors, you have to have solutions for the problems

Necessity and Requirements of a Collaborative Effort to Develop a Large Wind Turbine Blade Test Facility in North America
The wind power industry in North America has an immediate need for larger blade test facilities to ensure the survival of the industry. Blade testing is necessary to meet certification and investor requirements and is critical to achieving the reliability and blade life needed for the wind turbine industry to succeed. The U.S. Department of Energy's (DOE's) Wind Program is exploring options for collaborating with government, private, or academic entities in a partnership to build larger blade test facilities in North America capable of testing blades up to at least 70 m in length. The National Renewable Energy Laboratory (NREL) prepared this report for DOE to describe the immediate need to pursue larger blade test facilities in North America, categorize the numerous prospective partners for a North American collaboration, and document the requirements for a North American test facility
Scaling the Incompressible Richtmyer-Meshkov Instability
We derive a scaling relation for Richtmyer-Meshkov instability of incompressible fluids. The relation is tested using both numerical simulations and experimental data. We obtain collapse of growth rates for a wide range of initial conditions by using vorticity and velocity scales associated with the interfacial perturbations and the acceleration impulse. A curve fit to the collapsed growth rates yields a fairly universal model for the mixing layer thickness versus time

Onset of Convection in Two Liquid Layers with Phase Change
We perform linear stability calculations for horizontal fluid bilayers that can undergo a phase transformation, taking into account both buoyancy effects and thermocapillary effects in the presence of a vertical temperature gradient. We compare the familiar case of the stability of two immiscible fluids in a bilayer geometry with the less-studied case that the two fluids represent different phases of a single-component material, e.g., the water-steam system. The two cases differ in their interfacial boundary conditions: the condition that the interface is a material surface is replaced by the continuity of mass flux across the interface, together with an assumption of thermodynamic equilibrium that in the linearized equations represents the Clausius-Clapeyron relation relating the interfacial temperature and pressures. For the two-phase case, we find that the entropy difference between the phases plays a crucial role in determining the stability of the system. For small values of the entropy difference between the phases, the two-phase system can be linearly unstable to either heating from above or below. The instability is due to the Marangoni effect in combination with the effects of buoyancy (for heating from below). For larger values of the entropy difference the two-phase system is unstable only for heating from below, and the Marangoni effect is masked by effects of the entropy difference. To help understand the mechanisms driving the instability on heating from below we have performed both long-wavelength and short-wavelength analyses of the two-phase system. The short-wavelength analysis shows that the instability is driven by a coupling between the flow normal to the interface and the latent heat generation at the interface. The mechanism for the large wavelength instability is more complicated, and the detailed form of the expansion is found to depend on the Crispation and Bond numbers as well as the entropy difference. The two-phase system allows a conventional Rayleigh-Taylor instability if the heavier fluid overlies the lighter fluid; applying a temperature gradient allows a stabilization of the interface

Plans for Testing the NREL Unsteady Aerodynamics Experiment 10m Diameter HAWT in the NASA Ames Wind Tunnel: Minutes, Conclusions, and Revised Text Matrix from the 1st Science Panel Meeting
Currently, the NREL Unsteady Aerodynamics Experiment (UAE) research turbine is scheduled to enter the NASA Ames 80-ft x 120-ft wind tunnel in early 2000. To prepare for this 3-week test, a Science Panel meeting was convened at the National Wind Technology Center (NWTC) in October 1998. During this meeting, the Science Panel and representatives from the wind energy community provided numerous detailed recommendations regarding test activities and priorities. The Unsteady Aerodynamics team of the NWTC condensed this guidance and drafted a detailed test plan. This test plan represents an attempt to balance diverse recommendations received from the Science Panel meeting, while taking into account multiple constraints imposed by the UAE research turbine, the NASA Ames 80-ft x 120-ft wind tunnel, and other sources. The NREL-NASA Ames wind tunnel tests will primarily be focused on obtaining rotating blade pressure data. NREL has been making these types of measurements since 1987 and has considerable experience in doing so. The purpose of this wind tunnel test is to acquire accurate quantitative aerodynamic and structural measurements, on a wind turbine that is geometrically and dynamically representative of full-scale machines, in an environment free from pronounced inflow anomalies. These data will be exploited to develop and validate enhanced engineering models for designing and analyzing advanced wind energy machines
A qualitative study exploring medication management in people with dementia living in the community and the potential role of the community pharmacist
Background The prevalence of dementia is increasing rapidly. People with dementia may be prescribed complex medication regimens, which may be challenging for them and any carers involved to safely manage. Objective To describe and understand the key challenges, in relation to medication issues, experienced by people with dementia and their informal carers dwelling in the community and the potential role of community pharmacists. Design Qualitative semi‐structured interviews. Participants People with dementia, informal carers and health and social care professionals (HSCPs). Results Thirty‐one participants (eleven informal carers, four people with dementia and sixteen HSCPs) were interviewed. Three key themes were identified: the key challenges, improving medication management and the role of pharmacists. The caring role commonly included responsibility for medication management which created both practical problems and an emotional burden. This burden was worsened by any difficulty in obtaining support and if the person with dementia was on a complex regimen. Participants believed that the process could be improved by coordinated and on‐going support from HSCPs, which should focus on the informal carer. Medication reviews, particularly when conducted in the home environment, could be helpful. Conclusion Medication management for people with dementia living in the community is a complex process, and informal carers have a key role, which they frequently find challenging. Community pharmacists could have an enhanced role in this area, but would need to work within a more multidisciplinary environment outside the pharmacy
