Ambulatory blood pressure monitoring to assess antihypertensive therapy in private practice

Non-invasive ambulatory blood pressure monitoring has proved to be very useful in evaluating hypertensive patients. However, most previous studies were performed in specialised centres. Here the results of two trials are presented in which private physicians used ambulatory BP monitoring to assess the efficacy of antihypertensive drugs. The results were very similar to those observed previously in specialised clinics. In the individual patient, the level of ambulatory recorded pressure could not be predicted based on BP readings taken at the doctor's office. Also, the BP response to antihypertensive therapy was more reproducible when evaluated by ambulatory BP monitoring than by the doctor. Thus, the use of noninvasive ambulatory BP monitoring is also very appropriate in everyday practice for the management of hypertensive patients.

Alternatives for Rural Roads, HR-242, 1989

Much of the nation's rural road system is deteriorating. Many of the roads were built in the 1880s and 1890s with the most recent upgrading done in the 1940s and 1950s. Consequently, many roads and bridges do not have the capacity for the increased loads, speed, and frequent use of today's vehicles. Because of the growing demands and a dense county road system (inherited from the land settlement policies two centuries ago), revenue available to counties is inadequate to upgrade andmaintain the present system. Either revenue must be increased - an unpopular option - or costs must be reduced. To examine cost-saving options, Iowa State University conducted a study of roads and bridges in three 100 square mile areas in Iowa: • A suburban area • A rural area with a large number of paved roads, few bridges, and a high agricultural tax base and •A more rural area in a hilly terrain with many bridges and gravel roads, and a low agricultural tax base. A cost-benefit analysis was made on the present road system in these areas on such options as abandoning roads with limited use, converting some to private drives, and reducing maintenance on these types of roads. In only a few instances does abandonment of low traffic volume roads produce cost savings for counties and abutting land owners that exceed the additional travel costs to the public. In this study, the types of roads that produced net savings when abandoned were: • A small percentage (less than 5 percent) of the nonpaved county roads in the suburban area. However, net savings were very small. Cost savings from reducing the county road system in urbanized areas are very limited. • Slightly more than 5 percent of the nonpaved county roads in the most rural area that had a small number of paved county roads. • More than 12 percent of the nonpaved roads in the rural area that had a relatively large number of paved county and state roads. Converting low-volume roads to low-maintenance or Service B roads produces the largest savings of all solutions considered. However, future bridge deterioration and county liability on Service B roads are potential problems. Converting low-volume roads to private drives also produces large net savings. Abandonment of deadend roads results in greater net savings than continuous roads. However, this strategy shifts part of the public maintenance burden to land owners. Land owners also then become responsible for accident liability. Reconstruction to bring selected bridges with weight restrictions up to legal load limits reduces large truck and tractor-wagon mileage and costs. However, the reconstruction costs exceeded the reduction in travel costs. Major sources of vehicle miles on county roads are automobiles used for household purposes and pickup truck travel for farm purposes. Farm-related travel represents a relatively small percent of total travel miles, but a relatively high percentage of total travel costs.

Recycled Portland Cement Concrete Pavement in Iowa, HR-506, 1984

In recent years, there has been an increased interest in conservation of our resources, preservation of our environment and maintaining our ecology. Recycling of materials is a procedure that will immediately contribute to all of these desirable end results. Our economy is built on private enterprise and profit incentive and in the past, with abundant inexpensive resources, there was little incentive to recycle. Shortages of materials and energy (once considered abundant) along with regulations to protect the environment have emphasized the need for recycling. These environmental conditions coupled with the loss of purchase power by inflation has generated more interest in recycling in the transportation field. The Iowa Department of Transportation (Iowa DOT) is interested in recycling portland cement concrete (pcc) pavement to: 1. Provide aggregate where high quality aggregate is no longer economically available. 2. Eliminate the need for locations to waste the large amount of pavement rubble. 3. Conserve the present aggregate sources. 4. Reduce the need for disrupting land for quarrying purposes. 5. Save fuel and energy by reducing aggregate transportation.

20 Native Trees to Plant, January 25, 2010

If you have ever flown in an airplane over Iowa, you would see that our woodlands are scattered along the rivers and streams and areas too steep to farm. You would also see a green carpet of trees within out cities and towns. Did you know the 90% of the over 2.7 million acres of forest in Iowa is owned by over 138,000 different private owners? Or that 30% of the land cover in a typical Iowa community if covered by trees? Trees are vital for the protection of our drinking water supply, critical for wildlife habitat, and help sustain employment of over 7,000 Iowans in the wood products industry. This booklet "20 Native trees to Plant" will help you gain a greater knowledge about Iowa's trees and forests. Learn about and enjoy Iowa's trees. Consider ways that you can improve our environment by planting and caring for Iowa's trees and forests.

Local Public-Services Provision under Public-Private Partnerships : Contractual Design and Contracting Parties Incentives

When deciding to resort to a PPP contract for the provision of a local public service, local governments have to consider the demand risk allocation between the contracting parties. In this article, I investigate the effects of demand risk allocation on the accountability of procuring authorities regarding consumers changing demand, as well as on the cost-reducing effort incentives of the private public-service provider. I show that contracts in which the private provider bears demand risk motivate more the public authority from responding to customer needs. This is due to the fact that consumers are empowered when the private provider bears demand risk, that is, they have the possibility to oust the private provider in case of non-satisfaction with the service provision, which provides procuring authorities with more credibility in side-trading and then more incentives to be responsive. As a consequence, I show that there is a lower matching with consumers' preferences over time when demand risk is on the public authority rather than on the private provider, and this is corroborated in the light of two famous case studies. However, contracts in which the private provider does not bear demand risk motivate more the private provider from investing in cost-reducing efforts. I highlight then a tradeoff in the allocation of demand risk between productive and allocative efficiency. The striking policy implication of this article for local governments would be that the current trend towards a greater resort to contracts where private providers bear little or no demand risk may not be optimal. Local governments should impose demand risk on private providers within PPP contracts when they expect that consumers' preferences over the service provision will change over time.

09028-014 Tributary B to Fourmile Creek Final Report

The city of Ankeny is submitting this WIRB application for development of green urban stormwater practices on city and private property in the Fourmile Creek watershed. The stormwater project proposed includes stream restoration of the SE Tributary to Fourmile Creek (Tributary B), including weirs, bank shaping, toe protection, trees, and native plantings. The project also includes the creation of a native buffer along the stream channel in the city’s Summerbrook Park, installing four native planting beds, installing a pervious surface trail, installing a series of rain gardens/biorentention cells, and installing educational signage. Polk County Soil and Water Conservation District has committed $17,000 towards the native buffer and rain garden/biorentention cell. The city of Ankeny was also awarded a $100,000 I-JOBS grant from IDNR to complete the stormwater retrofit practices. The largest component of this project is public education. Our vision for this project is to take the entire 281 acre watershed and address it as a whole. We want to make a collaborative watershed that not only addresses the water entering the stream channel through adjacent properties, but takes each individual parcel within the watershed and strives to reduce contributions to the stormwater system. The stormwater issues of concern for Tributary B include stormwater volume, sediment, and nutrients. The stream restoration, best management practices (BMP) at Summerbrook Park, and BMPs on private property should help decrease the volume of stormwater and reduce the amount of sediment and nutrients that enter Tributary B and ultimately Fourmile Creek.

Climate Change or Land Use Dynamics: Do We Know What Climate Change Indicators Indicate?

Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indicators of climate change impacts that are based on the optimal thermal environment and averagelatitude of the distribution of bird species present at local communities. We used multiple regression models to relate the variation in climate change indicators to: i) environmental temperature; and ii) three landscape gradients reflecting important current land use change processes (land abandonment, fire impacts and urbanization), all of them having forest areas at their positive extremes. We found that, with few exceptions, landscape gradients determined the figures of climate change indicators as strongly as temperature. Bird communities in forest habitats had colder-dwelling bird species with more northerndistributions than farmland, burnt or urban areas. Our results show that land use changes can reverse, hide or exacerbate our perception of climate change impacts when measured through community-level climate change indicators. We stress the need of an explicit incorporation of the interactions between climate change and land use dynamics to understand what are current climate change indicators indicating and be able to isolate real climate change impacts
