No full textScope, Scale, and Sustainability: What It Takes to Create Lasting Community Change
No full text· This article examines success factors that relate specifically to the ability of a comprehensive community initiative (CCI) to achieve the scope and scale required to generate community-level outcomes and to sustain those positive impacts over time.
· The CCIs selected for study represent a wide range of goals, strategies, and organizational structures.
· Six factors were found to cut across scope, scale, and sustainability. These factors include having a single broker or entity that holds the vision of the change effort; clearly defined roles; alignment among interventions, resources, and geography; meaningful community engagement; competent leadership and staff; and strategic, cross-level relationships.
· Additional factors were found to relate to success in achieving scope, scale, or sustainability individually.
· Lessons include to plan, operate, and evaluate based on a systems- and community-change framework; choose focused and affordable strategies; build the capacity to use data; and plan for change and conflict
Looking for Genres on the World Wide Web: Content Analysis of American Author Web Sites
No full textPoster and handouts for presentation at American Library Association Annual Conference, Chicago, July 11, 2009.This project entails content analysis of 200 websites for authors commonly taught in university-level American literature survey courses. Using a faceted classification scheme to categorize site content, the researchers explore the extent to which consistency has developed in the scope and content of Web sites for authors in the canon of American literature. The goal is to identify both the full range of unique content on these Web sites and, within that range, the core content elements that comprise the “American Author Web Site” genre. The authors also gathered biographical details on each author, to consider the question of whether Web site content varies by an author’s gender or racial background. Ultimately, the goal is to identify a set of common and/or “best” practices for content and organization of author Web sites that will assist both undergraduate students and advanced researchers looking for author information on the Web, as well as site designers hoping to create quality resources for these users. In the choice of subject, size of the sample, and novelty of the approach, this promises to be a unique project that will interest librarians, web developers, and literature researchers alike.Library Faculty Research Fun

No full textA comparative study of the Finnish 4-H organization and the Wisconsin 4-H organization
No full textPlan BThe education of today’s youth, tomorrow’s future, is the focus of the 4-H organization. The aim of the 4-H program is to develop life skills in youth using hands-on learning. 4-H began in the heartland of America in the early 1900’s and soon stretched around the globe. 4-H or a partner organization of 4-H can be found in over 63 countries in the world (V. Gobeli, personal communication, February 25, 2002). The programming, structure, and principles of 4-H programs around the world are all based on the program that began in the United States, but the methods used are different in every country. It is even different among states in the United States. Each program has unique ideas used in the education of youth, but little communication exists to share these ideas among countries. The purpose of this study is to compare another country’s 4-H program to the program that has been long established in Wisconsin. The goal of the study is to show the similarities and difference of two programs that have been created using the same theme, “learning by doing.” Due to the scope of this research, the researcher chose to look only at one country. The country of Finland was chosen for comparison because of its location, similar structure, and its well-established example of European youth programming. The researcher looked at the history of the two programs to help establish the similarities and difference that might exist. The Finnish 4-H Federation began after two men visited the United States and observed the success of club work administered by the United States Department of Agriculture. The program ideas were changed to fit the needs of the Finnish people, with the key concept of life skill development remaining the same. The researcher also found that many articles have been written to show an importance in international programming and international travel. The research was done using ethnographic research along with a qualitative written survey and various interviews. The written survey was used to gain basic information before ethnographic research began. The research revealed that although the programs have the same basic goal, the two programs are very different. The largest differences were seen in projects offered, staff roles, leaders participation, and competition. It was found that both 4-H programs contained ideas of superior quality. If these ideas were shared, it could help to improve the program in the other country. The research not only compared the two programs, but also recommended further programs or studies that could be established based on the research performed
Towards critical low-temperature relaxation indicators for effective rejuvenation efficiency evaluation of rejuvenator-aged bitumen blends
No full textThe relaxation behavior affected by aging and rejuvenation plays a crucial role in its low-temperature cracking potential of bitumen. However, there are limited studies on the relaxation performance of rejuvenated bitumen under different rejuvenation conditions. This paper aims to propose critical indicators to assess the rejuvenation efficiency of low-temperature relaxation performance of various rejuvenated binders. The effects of rejuvenator type/dosage and aging level on relaxation parameters are investigated. The τ50s, t25%, and A are recommended as critical indicators based on their high sensitivities to influence factors and rejuvenation percentage scope. Additionally, molecular dynamic simulation outputs on virgin/aged bitumen and rejuvenators explain the difference in rejuvenation effectiveness of different rejuvenators. The results show that bio-oil rejuvenator exhibits the highest efficiency on regenerating the relaxation performance. All relaxation parameters of aged bitumen can be regenerated by adding rejuvenators. MD simulations reveal that the molecular mobility and free volume ratio of rejuvenators mainly cause the difference in rejuvenation efficiency on the relaxation property between various rejuvenators. The diffusion capacity of rejuvenator shows a more dominant effect on rejuvenation efficiency than fractional free volume.Pavement Engineerin
Production Performance of Radial Jet Drilled Laterals in Tight Gas Reservoirs in the Netherlands
No full textIn the Netherlands, a significant number (25+) of small tight natural gas fields are stranded. They are classified, according to the PRMS definition, as ‘contingent resources’. The combination of low GIIP and low permeability currently do not allow these fields to be developed economically without stimulation, which is usually required to produce tight gas reservoirs. The recent change in legislation on hydraulic fracturing increases the need for a more cost effective and politically accepted alternative. Since natural gas has played, and will continue to play an important role in the energy security of the Netherlands, alternative methods are considered to extract these stranded resources. Radial jet drilling could be such an alternative method to develop these reservoirs in a cost effective, environmental friendly and socially acceptable manner. In this report, a numerical reservoir simulator is used to compare the production performance of a synthetic low permeable homogeneous reservoir based on three development options: a conventional vertical well, a vertical well stimulation through radial jet drilling and one case where the vertical well is stimulated through hydraulic fracturing. The static and dynamic models are based on typical tight gas reservoir properties as found in the Netherlands. The objectives are: to determine the operational scope / boundary conditions for the application potential of radial jet drilling, to identify the reservoir- and well variables that control the effectiveness and production performance, and to evaluate the economics. The comparison of the development option includes a sensitivity and uncertainty analysis of the well and reservoir performance and the impact it has on the economic viability. The simulations demonstrate that the laterals appear to be most effective in low permeable (~0.1 mD) reservoirs, reservoirs with near-well bore formation damage, with lower initial water saturation's, depleted reservoirs and thin reservoirs. The laterals appear less effective in more permeable reservoirs and reservoirs with high horizontal-to-vertical anisotropy. The application of small diameter laterals generally results in a recovery improvement factor of 2-3.5 compared to a vertical well. The initial gas production improves with a factor 4-7. The small diameter laterals become effective for reservoirs with permeabilities lower than 10 mD. In reservoirs with a permeability lower than 0.1 mD the application results in a recovery factor improvement of at least 2. The lateral length is the well design parameter that has the most profound impact on the recovery factor. The economics demonstrate that the onshore application of radial jet drilling as a stimulation method is economically feasible and robust whereas a vertical well is economically very marginal. The offshore application of radial jet drilling is only feasible for stranded volumes 1 BCM in combination with a re-entry scenario.Petroleum EngineeringGeoscience & EngineeringCivil Engineering and Geoscience
