Planning, Developing, and Implementing the Iowa Pavement Marking Management System (IPMMS): Phases I and II, 2006

With an annual pavement marking program of approximately $2 million and another $750 thousand invested in maintenance of durable markings each year, the Iowa DOT is seeking every opportunity to provide all-year markings staying in acceptable condition under all weather conditions. The goal of this study is to analyze existing pavement marking practices and to develop a prototype Pavement Marking Management System (PMMS). This report documents the first two phases of a three-phase research project. Phase I includes an overview of the Iowa DOT’s existing practices and a literature review regarding pavement marking practices in other states. Based on this information, a work plan was developed for Phases II and III of this study. Phase II organized the key components necessary to develop a prototype PMMS for the Iowa DOT. The two primary components are (1) performance/life cycle curves for pavement marking products, and (2) an application matrix tailored to the pavement marking products and roadway and environmental conditions faced by the Iowa DOT. Both components will continue to be refined and tailored to Iowa materials and conditions as more performance data becomes available.

Pediatric advance care planning: a systematic review.

BACKGROUND AND OBJECTIVES: Advance care planning (ACP) is increasingly regarded as the gold standard in the care of patients with life-limiting illnesses. Research has focused on adults, but ACP is also being practiced in pediatrics. We conducted a systematic review on empirical literature on pediatric ACP (pACP) to assess current practices, effects, and perspectives of pACP. METHODS: We searched PubMed, BELIT, and PSYCinfo for empirical literature on pACP, published January 1991 through January 2012. Titles, abstracts, and full texts were screened by 3 independent reviewers for studies that met the predefined criteria. The evidence level of the studies was assessed. Relevant study outcomes were retrieved according to predefined questions. RESULTS: We included 5 qualitative and 8 quantitative studies. Only 3 pACP programs were identified, all from the United States. Two of them were informed by adult programs. Major pACP features are discussions between families and care providers, as well as advance directives. A chaplain and other providers may be involved if required. Programs vary in how well they are evaluated; only 1 was studied by using a randomized controlled trial. Preliminary data suggest that pACP can successfully be implemented and is perceived as helpful. It may be emotionally relieving and facilitate communication and decision-making. Major challenges are negative reactions from emergency services, schools, and the community. CONCLUSIONS: There are few systematic pACP programs worldwide and none in Europe. Future research should investigate the needs of all stakeholders. In particular, the perspective of professionals has so far been neglected.

Feasibility of Visualization and Simulation Applications to Improve Work Zone Safety and Mobility

Visualization is a relatively recent tool available to engineers for enhancing transportation project design through improved communication, decision making, and stakeholder feedback. Current visualization techniques include image composites, video composites, 2D drawings, drive-through or fly-through animations, 3D rendering models, virtual reality, and 4D CAD. These methods are used mainly to communicate within the design and construction team and between the team and external stakeholders. Use of visualization improves understanding of design intent and project concepts and facilitates effective decision making. However, visualization tools are typically used for presentation only in large-scale urban projects. Visualization is not widely accepted due to a lack of demonstrated engineering benefits for typical agency projects, such as small- and medium-sized projects, rural projects, and projects where external stakeholder communication is not a major issue. Furthermore, there is a perceived high cost of investment of both financial and human capital in adopting visualization tools. The most advanced visualization technique of virtual reality has only been used in academic research settings, and 4D CAD has been used on a very limited basis for highly complicated specialty projects. However, there are a number of less intensive visualization methods available which may provide some benefit to many agency projects. In this paper, we present the results of a feasibility study examining the use of visualization and simulation applications for improving highway planning, design, construction, and safety and mobility.

Métropolisation, morphologie urbaine et développement durable : transformations urbaines et régulation de l'étalement : le cas de l'agglomération lausannoise

Résumé Métropolisation, morphologie urbaine et développement durable. Transformations urbaines et régulation de l'étalement : le cas de l'agglomération lausannoise. Cette thèse s'inscrit clans la perspective d'une analyse stratégique visant à un définir et à expliciter les liens entre connaissance, expertise et décision politique. L'hypothèse fondamentale qui oriente l'ensemble de ce travail est la suivante : le régime d'urbanisation qui s'est imposé au cours des trente dernières années correspond à une transformation du principe morphogénétique de développement spatial des agglomérations qui tend à alourdir leurs bilans écologiques et à péjorer la qualité du cadre de vie des citadins. Ces enjeux environnementaux liés aux changements urbains et singulièrement ceux de la forme urbaine constituent un thème de plus en plus important dans la recherche de solutions d'aménagement urbain dans une perspective de développement durable. Dans ce contexte, l'aménagement urbain devient un mode d'action et une composante de tout premier ordre des politiques publiques visant un développement durable à l'échelle locale et globale. Ces modalités de développement spatial des agglomérations émergent indiscutablement au coeur de la problématique environnementale. Or si le concept de développement durable nous livre une nouvelle de de lecture des territoires et de ses transformations, en prônant le modèle de la ville compacte et son corollaire la densification, la traduction à donner à ce principe stratégique reste controversée, notamment sous l'angle de l'aménagement du territoire et des stratégies de développement urbain permettant une mise en oeuvre adéquate des solutions proposées. Nous avons ainsi tenté dans ce travail de répondre à un certain nombre de questions : quelle validité accorder au modèle de la ville compacte ? La densification est-elle une réponse adéquate ? Si oui, sous quelles modalités ? Quelles sont, en termes de stratégies d'aménagement, les alternatives durables au modèle de la ville étalée ? Faut-il vraiment densifier ou simplement maîtriser la dispersion ? Notre objectif principal étant in fine de déterminer les orientations et contenus urbanistiques de politiques publiques visant à réguler l'étalement urbain, de valider la faisabilité de ces principes et à définir les conditions de leur mise en place dans le cas d'une agglomération. Pour cela, et après avoir choisi l'agglomération lausannoise comme terrain d'expérimentation, trois approches complémentaires se sont révélées indispensables dans ce travail 1. une approche théorique visant à définir un cadre conceptuel interdisciplinaire d'analyse du phénomène urbain dans ses rapports à la problématique du développement durable liant régime d'urbanisation - forme urbaine - développement durable ; 2. une approche méthodologique proposant des outils d'analyse simples et efficaces de description des nouvelles morphologies urbaines pour une meilleure gestion de l'environnement urbain et de la pratique de l'aménagement urbain ; 3. une approche pragmatique visant à approfondir la réflexion sur la ville étalée en passant d'une approche descriptive des conséquences du nouveau régime d'urbanisation à une approche opérationnelle, visant à identifier les lignes d'actions possibles dans une perspective de développement durable. Cette démarche d'analyse nous a conduits à trois résultats majeurs, nous permettant de définir une stratégie de lutte contre l'étalement. Premièrement, si la densification est acceptée comme un objectif stratégique de l'aménagement urbain, le modèle de la ville dense ne peut être appliqué saris la prise en considération d'autres objectifs d'aménagement. Il ne suffit pas de densifier pour réduire l'empreinte écologique de la ville et améliorer la qualité de vie des citadins. La recherche d'une forme urbaine plus durable est tributaire d'une multiplicité de facteurs et d'effets de synergie et la maîtrise des effets négatifs de l'étalement urbain passe par la mise en oeuvre de politiques urbaines intégrées et concertées, comme par exemple prôner la densification qualifiée comme résultante d'un processus finalisé, intégrer et valoriser les transports collectifs et encore plus la métrique pédestre avec l'aménagement urbain, intégrer systématiquement la diversité à travers les dimensions physique et sociale du territoire. Deuxièmement, l'avenir de ces territoires étalés n'est pas figé. Notre enquête de terrain a montré une évolution des modes d'habitat liée aux modes de vie, à l'organisation du travail, à la mobilité, qui font que l'on peut penser à un retour d'une partie de la population dans les villes centres (fin de la toute puissance du modèle de la maison individuelle). Ainsi, le diagnostic et la recherche de solutions d'aménagement efficaces et viables ne peuvent être dissociés des demandes des habitants et des comportements des acteurs de la production du cadre bâti. Dans cette perspective, tout programme d'urbanisme doit nécessairement s'appuyer sur la connaissance des aspirations de la population. Troisièmement, la réussite de la mise en oeuvre d'une politique globale de maîtrise des effets négatifs de l'étalement urbain est fortement conditionnée par l'adaptation de l'offre immobilière à la demande de nouveaux modèles d'habitat répondant à la fois à la nécessité d'une maîtrise des coûts de l'urbanisation (économiques, sociaux, environnementaux), ainsi qu'aux aspirations émergentes des ménages. Ces résultats nous ont permis de définir les orientations d'une stratégie de lutte contre l'étalement, dont nous avons testé la faisabilité ainsi que les conditions de mise en oeuvre sur le territoire de l'agglomération lausannoise. Abstract This dissertation participates in the perspective of a strategic analysis aiming at specifying the links between knowledge, expertise and political decision, The fundamental hypothesis directing this study assumes that the urban dynamics that has characterized the past thirty years signifies a trans-formation of the morphogenetic principle of agglomerations' spatial development that results in a worsening of their ecological balance and of city dwellers' quality of life. The environmental implications linked to urban changes and particularly to changes in urban form constitute an ever greater share of research into sustainable urban planning solutions. In this context, urban planning becomes a mode of action and an essential component of public policies aiming at local and global sustainable development. These patterns of spatial development indisputably emerge at the heart of environmental issues. If the concept of sustainable development provides us with new understanding into territories and their transformations, by arguing in favor of densification, its concretization remains at issue, especially in terms of urban planning and of urban development strategies allowing the appropriate implementations of the solutions offered. Thus, this study tries to answer a certain number of questions: what validity should be granted to the model of the dense city? Is densification an adequate answer? If so, under what terms? What are the sustainable alternatives to urban sprawl in terms of planning strategies? Should densification really be pursued or should we simply try to master urban sprawl? Our main objective being in fine to determine the directions and urban con-tents of public policies aiming at regulating urban sprawl, to validate the feasibility of these principles and to define the conditions of their implementation in the case of one agglomeration. Once the Lausanne agglomeration had been chosen as experimentation field, three complementary approaches proved to be essential to this study: 1. a theoretical approach aiming at definying an interdisciplinary conceptual framework of the ur-ban phenomenon in its relation to sustainable development linking urban dynamics - urban form - sustainable development ; 2. a methodological approach proposing simple and effective tools for analyzing and describing new urban morphologies for a better management of the urban environment and of urban planning practices 3. a pragmatic approach aiming at deepening reflection on urban sprawl by switching from a descriptive approach of the consequences of the new urban dynamics to an operational approach, aiming at identifying possible avenues of action respecting the principles of sustainable development. This analysis approach provided us with three major results, allowing us to define a strategy to cur-tail urban sprawl. First, if densification is accepted as a strategic objective of urban planning, the model of the dense city can not be applied without taking into consideration other urban planning objectives. Densification does not suffice to reduce the ecological impact of the city and improve the quality of life of its dwellers. The search for a more sustainable urban form depends on a multitude of factors and effects of synergy. Reducing the negative effects of urban sprawl requires the implementation of integrated and concerted urban policies, like for example encouraging densification qualified as resulting from a finalized process, integrating and developing collective forms of transportation and even more so the pedestrian metric with urban planning, integrating diversity on a systematic basis through the physical and social dimensions of the territory. Second, the future of such sprawling territories is not fixed. Our research on the ground revea-led an evolution in the modes of habitat related to ways of life, work organization and mobility that suggest the possibility of the return of a part of the population to the center of cities (end of the rule of the model of the individual home). Thus, the diagnosis and the search for effective and sustainable solutions can not be conceived of independently of the needs of the inhabitants and of the behavior of the actors behind the production of the built territory. In this perspective, any urban program must necessarily be based upon the knowledge of the population's wishes. Third, the successful implementation of a global policy of control of urban sprawl's negative effects is highly influenced by the adaptation of property offer to the demand of new habitat models satisfying both the necessity of urbanization cost controls (economical, social, environ-mental) and people's emerging aspirations. These results allowed us to define a strategy to cur-tail urban sprawl. Its feasibility and conditions of implementation were tested on the territory of the Lausanne agglomeration.

Watershed Planning Advisory Council 2015 Annual Report, December 10, 2015

The Watershed Planning Advisory Council (WPAC) was established by the Iowa Legislature (see Appendix A: Iowa Code 466B.31) to assemble a diverse group of stakeholders to make recommendations to state and federal agencies to protect water resources in Iowa. In 2015, WPAC prioritized the seven areas for recommendations outlined in 466B.31, and small work groups drafted recommendations for approval by the full membership.

Organization and Coordination of the Highway Planning Function in Iowa, HR-150, 1971

The Engineering Research Institute at Iowa State University studied the organization and procedures for highway planning by all levels of government and the coordination among various state agencies and local governments in Iowa. Study information was derived from interviews, questionnaires, and a review of the literature. Representatives from state transportation or highway organizations in all states responded to questionnaires. Additionally, selected upper and intermediate level personnel from highway organizations in seven other states were interviewed and a visit was made to one state transportation department. Within Iowa, employees were interviewed in the Highway Commission, Office for Planning and Programming, Development Commission, Commerce Commission, Conservation Commission, and Highway Patrol. Nearly 600 officials of local governments in Iowa contributed factual data and opinions through questionnaires and interviews. Private citizens and consultants also provided input to the investigation through their responses to questionnaires. Twelve recommendations to improve highway planning in Iowa were formulated as a result of this study.

Improved Employment Data for Transportation Planning, 1998

Transportation planners typically use census data or small sample surveys to help estimate work trips in metropolitan areas. Census data are cheap to use but are only collected every 10 years and may not provide the answers that a planner is seeking. On the other hand, small sample survey data are fresh but can be very expensive to collect. This project involved using database and geographic information systems (GIS) technology to relate several administrative data sources that are not usually employed by transportation planners. These data sources included data collected by state agencies for unemployment insurance purposes and for drivers licensing. Together, these data sources could allow better estimates of the following information for a metropolitan area or planning region: · Locations of employers (work sites); · Locations of employees; · Travel flows between employees’ homes and their work locations. The required new employment database was created for a large, multi-county region in central Iowa. When evaluated against the estimates of a metropolitan planning organization, the new database did allow for a one to four percent improvement in estimates over the traditional approach. While this does not sound highly significant, the approach using improved employment data to synthesize home-based work (HBW) trip tables was particularly beneficial in improving estimated traffic on high-capacity routes. These are precisely the routes that transportation planners are most interested in modeling accurately. Therefore, the concept of using improved employment data for transportation planning was considered valuable and worthy of follow-up research.

Revisiting sodium and water reabsorption with functional genomics tools.

PURPOSE OF REVIEW: The kidney plays an essential role in maintaining sodium and water balance, thereby controlling the volume and osmolarity of the extracellular body fluids, the blood volume and the blood pressure. The final adjustment of sodium and water reabsorption in the kidney takes place in cells of the distal part of the nephron in which a set of apical and basolateral transporters participate in vectorial sodium and water transport from the tubular lumen to the interstitium and, finally, to the general circulation. According to a current model, the activity and/or cell-surface expression of these transporters is/are under the control of a gene network composed of the hormonally regulated, as well as constitutively expressed, genes. It is proposed that this gene network may include new candidate genes for salt- and water-losing syndromes and for salt-sensitive hypertension. A new generation of functional genomics techniques have recently been applied to the characterization of this gene network. The purpose of this review is to summarize these studies and to discuss the potential of the different techniques for characterization of the renal transcriptome. RECENT FINDINGS: Recently, DNA microarrays and serial analysis of gene expression have been applied to characterize the kidney transcriptome in different in-vivo and in-vitro models. In these studies, a set of new interesting genes potentially involved in the regulation of sodium and water reabsorption by the kidney have been identified and are currently under detailed investigation. SUMMARY: Characterization of the kidney transcriptome is greatly expanding our knowledge of the gene networks involved in multiple kidney functions, including the maintenance of sodium and water homeostasis.
