Abstract The Cooperative Extension System's mission to “put scientific knowledge into practice” is a natural fit for practicing anthropologists. Two extension anthropologists present their work with the Iowa State University Extension and Outreach programs, Iowa Learning Farms and Water Rocks!, as a case study for how anthropological practice can be used to develop and implement successful extension programs. Added to the conversation is the element of advocacy in anthropological practice, with an examination of how using anthropological research and evaluation methods to understand targeted program audience perspectives better enables practitioners to advocate for environmental improvements and better meet the primary extension program objective of bringing practical, science-based solutions to real world problems.

Horticulture graduates entering the landscape industry will be faced with a multitude of complicated management decisions where they will need to integrate their understanding of plant science, site constraints, state and federal environmental regulations, and the human impact on the built landscape. To help students develop and refine their problem-solving skills, an interactive online case study was created. The case study was used in two different landscape horticulture courses at Iowa State University and Oregon State University. The case study centers on a residential backyard with eight landscape problem scenarios. Each scenario is identified on the clickable landscape map of the area and contains links to audio files, PDF documents, images, and Internet links. After investigating each scenario, students submit an analysis, diagnosis, and recommendation about the landscape problem via WebCT or Blackboard, depending on the institution. Student evaluation of the case study as a teaching tool was positive (3.5, where 1 = poor; 5 = excellent). Students answered additional questions using a scale where 1 = strongly disagree and 5 = strongly agree. As a result of using this teaching tool, students felt that they were able to summarize the data (3.9), diagnose the landscape problem (3.9), and make a recommendation to the homeowner (3.6). Further, they felt this teaching tool was an effective way to deliver information (3.9); the interactive format aided their learning (3.7); that they were comfortable using a web-based format (4.2); and they liked learning using case studies (4.1). Our goal is to make the case-study framework available to other teaching colleagues who can then add their own data.

The increasing availability of mobile technologies is allowing users to interact seamlessly with a variety of content anytime, anywhere. One of these new Web 2.0 technologies, or technologies that aim at enhancing and creating opportunities for user collaboration, is podcasting (Wikipedia, 2008; O’Reilly, 2005), an online audio and video publishing tool. Podcasts are increasingly being used by language educators and learners, yet in the educational realm, podcasting is still in a development phase as teachers and students are just beginning to experiment with ways to best use the technology. Therefore, few guidelines exist in terms of researching this new technology, specifically with regards to language learning and teaching (Rosell-Aguilar, 2007). In this chapter we begin to close this gap by first providing an overview of podcasting. We then discuss the potential of podcasting to transform ways in which languages are learned. In doing so, we cite illustrative examples of podcasts currently being used by language educators and students, and suggest ways in which the effects of this technology on language learning processes may be researched in order to make pedagogically sound decisions about using podcasts for language learning and teaching. After presenting a case study investigating the use of podcasts at Iowa State University, we conclude with a reflection on the potential for podcasts to transform language learning and teaching.

Strip Intercropping

AbstractStrip intercropping seeks to capture the biological efficiency of intercropping in traditional agricultural systems and is compatible with agricultural equipment used in the U.S. This efficiency stems from complementary use of resources by constituent crops and is a function of crop selection, strip width and orientation, weed control, and other factors. Strip intercropping requires a high level of management; further, some reports suggest the gains and losses more-or-less balance in actual production situations. These questions are best addressed by the performance of strip intercropping as implemented by farmers in production situations.Practical Farmers of Iowa (PFI) members have worked with Iowa State University agronomists to evaluate strip intercropping. For three years six farmers compared strip intercropping to field blocks of individual crops. The strip intercrop systems employed three crops: corn, soybeans, and small grains with a forage legume underseeding. The comparison systems, crops grown in sole-crop blocks, consisted of the same three crops on four farms (planting pattern comparison) or, on two farms, just corn and soybeans in rotation (systems comparison). Yields and field operations were recorded and entered in the Iowa State University Crop Enterprise Record System (CER) to derive gross profit, total production cost, and net profit for each crop component and for each cropping system on every farm. Strip intercropping net profit was generally greater than that in field blocks, and intercropping compared favorably with CER results obtained from corn-soybean rotations on other farms around Iowa. Land equivalent ratios (LER) were usually greater than 1.0, indicating satisfactory biological efficiency. Despite occasional problems, in this set of 18 site-years strip intercropping was associated with greater stability of net profit.

Research Directions

This paper concentrates on power places as perceived by the students in a 60,000 people college town in the United States. Power places are favourite outdoor locations that evoke positive emotions, and are conducive to relaxation and reduction of stress. Further understanding how location affects those places and the feelings of students will help planners and designers be more intentional as they create conditions favourable to the development of cities that are healthy, sustainable, resilient and smart. Research methodologies used in this paper include empirical cartography, mapping and space syntax. We conclude the paper with a discussion of the presented results and further research directions.
