A multiple case study of professional development and perspective change within the Cooperative Extensive Service

This multi-case study explored individual and organizational perspective change by analyzing two long-term, management-supported professional development courses within the Cooperative Extension Service (CES). Data sources consisted of a survey of course participants, and interviews of selected participants and course designers. More than one half of the participants in both courses self-reported a perspective change, although only 5 of the 16 participant interviews revealed premise reflection--a necessary condition in this study for a perspective change. Seven learning themes were identified, five of which were similar to the transformational learning phases identified by Mezirow (1991). The two themes not similar to Mezirow\u27s findings were affirmation and common language/shared meaning. These themes have implications for making perspective changes within organizations. Learning supports most frequently identified by participants were self-motivation, peer support, and instructor support. Learning was found to be insufficiently supported before and after the PD experience. A finding that emerged from cross-analysis was a process called liminality--a period of ambiguity where learners are caught between rejecting the introduced learning concepts and transforming their perspective. Recommendations based on the findings provide may guidance to future CES professional development managers and practitioners on how to affectively design professional development for perspective change in future courses

Anatomical And Mechanical Characteristics Of Woods Used To Manufacture Bassoons

Thesis (Ph.D.) University of Alaska Fairbanks, 2012The purpose of this dissertation was three-fold -- 1) to determine if anatomical characteristics and mechanical characteristics derived from tapping (the act of striking an object lightly) can be used to more accurately describe bassoon resonant wood than the characters in use now, 2) to determine if any Alaska hardwoods can be used to construct bassoons, and 3) to produce lists of potential North American hardwoods and resonant bassoon wood characters. The bassoon resonant woods (Acer spp., Dalbergia melanoxylon, and Pyrus spp.) were compared to a known non-resonant bassoon wood (Juglans nigra). Vessel length and width, fiber length, and axial parenchyma width were measured in sectioned and macerated wood slides, along with the ratios of crystalline cellulose, lignin, pectin, and other aromatics in the cell wall. Partial frequencies created from tapping specimens on each longitudinal face were measured from melodic and peak partial spectrograms, as well as the spectrum obtained from the beginning of the sound. MANOVA and univariate ANOVA showed the resonant woods were significantly different from the non-resonant Juglans nigra using the characters measured. These characters were then used to compare two Alaska hardwoods (Alnus rubra and Betula neoalaskana) to the temperate resonant woods (Acer spp. and Pyrus spp.) and the non-resonant Juglans nigra using k-means clustering, MANOVA, and univariate ANOVA. Both Alaska hardwoods grouped with the non-resonant Juglans nigra. Lastly a list of potential North American hardwoods to be checked anatomically was compiled, as well as a list of characters that combine those used now as well as characters found in this study

Development of a Versatile Section Analysis Tool (VSAT) for use in structural design with a seismic emphasis

The design of structural members subjected to seismic activity has progressed in recent years but does not yet include the effects of cold temperatures. In areas such as Alaska, the Midwest, East Coast, and even in some parts of the West Coast, this approach introduces a real deficiency as it is likely that an earthquake will occur during winter months. The current research program was initiated to address this deficiency by developing a section analysis tool program capable of defining the moment-curvature response in either warm or low temperatures. As part of this investigation, the stress-strain behavior of A706 Grade 60 mild steel reinforcement was studied under low temperatures (20°C to -40°C) to ensure that the effects of temperature is accurately accounted for in the newly developed analysis tool. In addition to mild steel, the effects of cold temperatures on the behavior of soil, unconfined concrete, and confined concrete are currently being examined by other researchers at Iowa State University. The Versatile Section Analysis Tool (VSAT) was developed to reduce the general limitations found in other programs. Amongst these limitations are limited available material models, lack of commonly used section shapes, and the exclusion of soil and low temperature effects. VSAT was constructed with many different features to provide versatility in how the user wishes to establish material properties for a particular analysis. VSAT includes the following features: permitting different cross-sections, defining normal strength or UHPC material properties, defining simplistic or sophisticated mild steel or prestressing steel material properties, allowing the addition of soil pressure, including a steel shell circular section, and accounting for low temperature effects on material behavior. The testing of mild steel reinforcement at low temperatures showed a quadratic increase in the yield and ultimate strengths of 5.1 and 6.3 percent, respectively, when lowering specimen temperatures from 20°C to -40°C. It was also found that the modulus of elasticity, ultimate strain, and strain hardening strain were insignificantly affected under the same conditions. Assumptions for the behavioral changes of concrete under low temperatures to be used in VSAT have been compiled from previous research until current testing can be completed. These assumptions will then be replaced with experimental data collected by this project\u27s partner researcher, Aaron Shelman. As portions of VSAT were completed, the program was continually verified to be functioning correctly. First, previously known material models were verified to coincide with those presented in this thesis by hand and within the newly developed program. Second, as shown in the verification section of this thesis, non-prestressed rectangular and circular sections were compared with King\u27s Program to ensure accuracy. UHPC H-shaped sections were also examined based upon the work and experimentation of Vande Voort et al. (2008). Unique features, where a comparison is impossible (i.e. temperature effects on the stress-strain behavior of mild steel reinforcement), have been carefully added to VSAT. The effects of these features have been checked, by hand, to ensure that the program is functioning properly. The development of VSAT has been successfully initiated and the results for particular sections have proven to be comparable with previously created section analysis programs. Further expansion of the program is possible as additional desired features become apparent. Due to time constraints and the scope of this project, any addition features and continual testing of the program was left for a successor to complete

Generation and characterization of virus-neutralizing bovine monoclonal antibodies to bovine herpesvirus 1 glycoproteins gB, gC, and gD

Three bovine monoclonal antibodies (MAb) which neutralized bovine herpesvirus 1 (BHV1) were generated using a unique `self-refusion\u27 method. Each was determined to be directed to one of the three major neutralization targets of BHV1 (gB, gC, and gD), and was capable of passive immunization in a laboratory rabbit intravenous challenge model. They were found to be specific for the immunizing BHV1 or for BHV1 and the closely related BHV5. The epitope specificities of two were identified using characterized murine MAb. The previously unidentified combination of epitope and virus reactivity of the two bovine MAb suggest a sequence-structural difference in gB between BHV1.1 and BHV5, and an epitope adjacent to a known epitope for the anti-gD bovine MAb. Anti-idiotypic antibodies were generated against one of the bovine MAb for possible use in vaccination. Bovine MAb may offer unique advantages for research and application in diagnostics, vaccine development, and in better understanding the bovine immune response to infectious disease

Making Rapid Change: Leaning 4-H

Nationwide, Extension is restructuring and searching for efficiencies due to reduced funding. When American Recovery and Reinvestment Act funds became available, the Iowa 4-H program used the funding allocated to support training the administrative team and key staff to improve 4-H statewide processes. Building a lean culture of streamlining processes and eliminating waste through the use of kaizen events helped redirect funding for priority work, as well as create team spirit

Planning for a residential agricultural and environmental education program at the Iowa 4-H Education and Natural Resources Center

Education programs are needed to increase awareness and implementation of sustainable agriculture goals and practices. Hands-on experiences, such as those offered by residential environmental and agricultural education programs, are an excellent way to spread the word about sustainable agriculture. A participatory planning process was used to determine the feasibility of providing this sort of program at the Iowa 4-H Center. An advisory group reviewed existing programs, evaluated target audience survey results, and began to develop a program plan

Reciprocal Subsidies and Food Web Pathways Leading to Chum Salmon Fry in a Temperate Marine-Terrestrial Ecotone

Stable isotope analysis was used to determine the relative proportions of terrestrial and marine subsidies of carbon to invertebrates along a tidal gradient (low-intertidal, mid-intertidal, high-intertidal, supralittoral) and to determine the relative importance of terrestrial carbon in food web pathways leading to chum salmon fry Oncorhynchus keta (Walbaum) in Howe Sound, British Columbia. We found a clear gradient in the proportion of terrestrially derived carbon along the tidal gradient ranging from 68% across all invertebrate taxa in the supralittoral to 25% in the high-intertidal, 20% in the mid-intertidal, and 12% in the low-intertidal. Stable isotope values of chum salmon fry indicated carbon contributions from both terrestrial and marine sources, with terrestrially derived carbon ranging from 12.8 to 61.5% in the muscle tissue of chum salmon fry (mean 30%). Our results provide evidence for reciprocal subsidies of marine and terrestrially derived carbon on beaches in the estuary and suggest that the vegetated supralittoral is an important trophic link in supplying terrestrial carbon to nearshore food webs
