Introduction Doerfert, Evans, Cartmell, & Irani (2007) reported on efforts to develop an International Framework and Agenda for Agricultural Communications Research in the next 5 years. Their article was based upon work done by teams collaboratively supported by the National Research Council, the American Association of Agricultural Education, and the USDA to identify priority areas for research under the umbrella theme of “knowledge management.” The third priority area identified was “Build Competitive Societal Knowledge and Intellectual Capabilities.” Under that general priority, there were two specific research questions that the current study was designed to address: 1. How can we gather and make available the widely scattered literature about agricultural communication? 2. How do we use communication networks, linkages, and approaches more effectively in agricultural knowledge management? The purpose of the present study is to examine broadly the types of agricultural communication research being done during the period 2000 to 2008. While three previous studies have examined patterns of research published in the Journal of Applied Communications, this study included a much broader collection of 391 agricultural communication research articles, books and theses/dissertations – four times as many articles as any of the previous three studies. Zumalt (2007) and Doerfert et al. (2007) both recognized the widely scattered nature of research literature in the agricultural communications field. One of the major accomplishments of the Agricultural Communications Documentation Center at the University of Illinois has been to amass more than 30,000 documents of various types concerning agricultural communication. The current study builds upon that database, but with a focus specifically on research. A second purpose matches the second research question: how to assist researchers in identifying those working in similar areas, and facilitating linkages among them for future research. By providing information about topics, authors, and their university/institutional affiliations, the present study is designed to facilitate future collaborative research and avoid duplication of research already carried out. Specifically, the research database created as a part of this study examines studies across a number of dimensions: • Agricultural topics being studied (the term agriculture is defined very broadly) • Communication medium or technology being studied • Research methodology used in the study • First author’s university or institutional affiliation • University or institutional affiliations of all authors • A listing of all authors included in the database The searchable database upon which the study is based is available to all interested agricultural communication scholars at: https://secure.jlmc.iastate.edu/app/agresearch 2

Literature Review and Methodological Approach Several past studies have examined agricultural communication research, but the current study is unique in several respects. Williams and Woods (2002) studied agricultural research published in the Journal of Applied Communications between 1992 and 2001. This study was replicated by Miller, Stewart & West (2006) who studied a total of 56 articles by 119 total authors published in the Journal of Applied Communications between 2000 and 2004. A third study by Edgar, Rutherford and Briers (2008) examined 91 articles by 222 total authors in the Journal of Applied Communications from 1997 to 2006. A strength of all three of these studies is that they focused exclusively on published research, and they identified themes across time. However, Zumalt (2007), in his review of 30,000 documents in the Agricultural Communication Documentation Center University of Illinois database, noted that agricultural communication publications including research are published in a wide variety of journals and venues. More than half of the core periodicals in the ACDC are from outside the traditional agriculture and life science literature. Thus, although Edgar, Rutherford and Briers (2008) established that the Journal of Applied Communications is known as an important journal for agricultural communication research, they also noted that it is far from being exhaustive. In fact, in the current study, only 53 of 613 distinct authors were identified as members of the Association for Communication Excellence (ACE), which publishes this journal. For this reason, the current study included agricultural communication research listed in three databases (Communication Abstracts, Dissertation Abstracts, and the Agricultural Communication Documentation Center at the University of Illinois). In addition to broadening the scope of research that is included, the current study also used a more sophisticated coding scheme. Williams & Woods (2002) developed coding categories for research themes that were utilized and amplified by Miller, Stewart & West (2006). Edgar, Rutherford and Briers (2008) began with the research themes provided by the previous studies, and then invited agricultural communication scholars to add to the list. They also coded for both “primary” and “secondary” themes, which allowed them to identify themes that were present even though they were not primary. Although most of the themes identified in all three studies focused on communication aspects such as “radio” or “information technology,” at least some such as “biotechnology communication” and “food, agriculture, natural resources, health and family” seemed to focus more on agricultural themes rather than communication themes. The current study coded the articles according to three categories: (1) Agricultural topic (environment, agriculture, rural, biotechnology, etc..); (2) Communication medium or area (general communication, newspapers, public relations, Internet, information technology, etc.); (3) Research methodology (survey, content analysis, case study, focus group, historical analysis, general logical analysis, etc.). Every article had at least one coded agricultural topical category, and most also identified a communication medium or area in the title and abstract. However, only about a third indicated a research method in the title and abstract. Edgar, Rutherford and Briers (2008) also coded for research methodology, providing a possible comparison with the current study. 3

Third, the current study makes it possible to examine research production by university, or even by individual scholars. Miller, Stewart & West (2006) also identified authors, and used them to indicate who were the “leaders” in the field. However, because there were only 56 articles, their analysis of authors was limited to six individuals who had published more than one article in a thematic area. One additional thing they did, which the current study could not do because of the volume of articles, was to examine the citations used in each of the 56 articles. These were also utilized to indicate who was being cited by thematic area. However, one limitation of this approach (recognized by the authors) was that many authors cited themselves frequently, so that the total number of citations did not necessarily represent independent recognition by others. Edgar, Rutherford and Briers (2008) also coded for authors without respect to whether they were first, second or third authors. This allowed them to identify publication frequency by author. Their study identified 12 authors who had published three or more articles during the period. Since some of the 12 authors often co-authored or even tri-authored articles, their approach did not make it possible to compare authors by home institutions since counting every author would double or triple-count the institution. In the current study, when articles were entered into the database the first author of each piece of research was identified by university/institution. This made it possible to count the productivity of each university/institution without double counting. It also made it possible to examine the actual research focus of the articles from each institution. In addition to coding the first author, the university/institutional affiliation of every author was also coded. This made it possible to list the total number of researchers from every university/institution who were publishing in the area of agricultural communication research. With this information, for example, one can list, by name, all of the individuals at one’s institution who have published articles in this area, either to see the range of individuals or determine who is most productive. Finally, a listing was made in alphabetical order of each individual in the database, along with his/her affiliation (and department or unit if possible). Overall, the goal was to identify the cadre of individuals who are working in this area, and make it possible to map this by topical area, institution or academic area. Benefits of knowing who is doing what research at other institutions are many. Evans & Prabha (1983) found in a national survey of agricultural communication scholars that there was a demonstrated need for access to the literature. More recently, despite the creation of the Agricultural Communication Documentation Center, Doerfert (2003) criticized previous researchers for unnecessary duplication of research, and urged researchers to become more aware of common research interests, and to be more collaborative in tackling them. Tucker (2004) has encouraged an examination of research as a means of determining both what has been done, as well as what has not been done. One other obvious use of the database of agricultural communication researchers created for the current study would be for those who wish to solicit more memberships in ACE and its research special interest group. 4

Article Selection Method Finding relevant agricultural communication research articles is a challenge, since as Prabha and Evans (1979) and Zumalt (2007) have noted, the research is very scattered and there is no one abstracting service that tracks all of them. Exclusively agricultural abstracting services such as AGRICOLA and CAB Abstracts have few articles about agricultural communication research. It was also found that the top 10 periodicals included only 28% of all agricultural communication articles identified (Prabha & Evans, 1982). In addition, more than half of the core periodicals in the Agricultural Communication Documentation Center come from outside the traditional agriculture and life science literature. Zumalt (2007) reported that although Communication Abstracts is a respected and accessible source for communication research, he found that a relatively small proportion of all agricultural communication research articles are included. Between 1978 and 2006, he found only 110 articles matching the search term “agriculture.” Much depends on the journals covered, the ways titles/abstracts/key terms are written, and the system by which librarians determine what to include. Relevant books, for example, may or may not be included. Thus, Communication Abstracts was seen as a starting point for the current study. Research articles containing any of the following terms, including multiple versions (agriculture, agricultural, etc.) were selected: agriculture, animal, biotechnology, crop, environment, extension, farm, fish, food, horse, horticulture, livestock, meat, plant, poultry, rural, science and/or risk, telecommunication). Articles could include the terms in a title, keyword, or searchable abstract. Articles that were exclusively devoted to international topics were deleted, although those that included some US data, and those that did not indicate clearly that they were exclusively international, were retained. A total of 90 articles were identified that matched the search criteria. Next, a search of the Agricultural Communication Documentation Center database was conducted. For this search, a list of relevant journals was constructed from the ACDC database, along with a search for books with relevant titles/abstracts. To be selected, an article or book had to be about research, and had to include an agricultural and communication term. Journals searched via ACDC included; Journal of Applied Communications, Journal of Extension, Development Communication Report, Agriculture and Human Values, Journalism and Mass Communication Quarterly, Journal of Communication, Journal of Agricultural Education, AgBioForum, Journal of Environmental Education, and Public Opinion Quarterly. The search process located a number of duplicates from the Communication Abstracts search, and these were deleted. Since only articles that included terms indicating that they were about agriculture or an agriculturally related topic were included, not all articles from these journals were used. For example, only 60 of the articles from the Journal of Applied Communications were included in the database. Book reviews, editorials, and some international articles were not included. A total of 203 additional studies were added using the ACDC database. The third addition to the database came from adding all theses and dissertations from Dissertation Abstracts that included both at least one communication term and one agricultural term. Communication terms included: advertising, communication, education, 5

information technology, internet, interpersonal, magazine, mass communication, newspaper, public relations, radio, reporting, television/film, and visual communication. A total of 79 dissertations and 19 theses were added. This resulted in a total of 391 separate studies of agricultural communication in the database. Results Some highlights from the database of 391 articles are presented here. However, researchers are invited to access the database and conduct their own tailored searches for particular topics, authors or institutions. The database is meant as a productive tool for agricultural communication researchers, and can be used for many different purposes. Table 1 compares research themes from the current study with the three previous studies that used the Journal of Applied Communications as the base. While the first three studies are roughly comparable, the current study divided themes into agricultural and communication units instead of one overall thematic classification. One finding, perhaps not surprising, is that biotechnology research has been increasing. It was absent from the themes in the 1992-2001 study, constituted 5.4% of the 56 studies from 2000-2004, and 6.6% of the 91studies from 1997-2006. In the current study, which used a database of 391 articles, biotechnology was a theme in 14.6% of published research. The difference may be due solely to the rising visibility of this area of research, but it also could be due to the fact that other journals such as AgBioforum are placing much more emphasis on communication research in this area. The fact that the previous studies coded articles mainly for their communication aspect rather than their agricultural aspect could also be a confounding factor. A second area of interest is science and risk communication. Miller, Stewart & West (2006) in their analysis of 2000-2004 JAC articles noted that “research on crisis and risk communications seems to be a common topic of discussion among practitioners and researchers in agricultural communication, but none of the articles published had these as the primary theme.” Edgar, Rutherford & Briers (2008) found two of 91 articles focused on risk/crisis communication. The current study found 11.3% of the 391 articles in the wider database focused on “science and risk communication” issues. This provides some evidence for concluding that this issue has in fact been covered more widely by journals other than JAC. It was the fifth-ranked agricultural thematic topic in the current study. In the area of communication themes, one of the dominant themes in the previous three studies was information technology (or information sources and technology), which occupied either first or second place in the rankings. In the current study, information technology as a category ranked sixth. Taken as a whole, the JAC research tended to focus on topics of greater interest to information processors and deliverers (writing, publications, distance education, professional development, etc.), while the current study tended to focus on more traditional media categories such as newspapers, Internet, Advertising, public relations, etc. 6

The Edgar, Rutherford & Briers (2008) study also examined research methods employed in JAC studies from 1997-2006. Table 2 shows the comparison between their results and the current study. It should be noted that while Edgar, Rutherford and Briers examined each entire article, the current study only searched title, abstract and key words. Only 106 of the 391 studies indicated the method used in title, abstract or keywords. This is a deficiency of the current study. Results show both studies rank “survey” as the most popular research methodology, with almost half of the JAC articles employing this method and slightly less than one-quarter of the more general database. Content analysis was also highly rated in both studies, taking second place (15.4%) in the JAC study, and third place with 19.8% in the current study. One area of difference was historical studies, which ranked sixth in the JAC study (4.4%) but second with 20.8% in the current study. Case studies were more frequent in the JAC study (9.9%) compared to 2.8% for the current study. In general, it appears that the larger database of studies used a more diverse group of research methods, while three-fourths of the JAC studies used either survey, content analysis or case study methods. The current study examined the 391 articles, books, and theses/dissertations by institution. A total of 132 separate university or institutional affiliations were found for the first authors of 358 of the articles. No university or institutional affiliation was available for the remaining 33, and they were excluded from the results. Table 3 shows the top 25. The complete list is shown in Appendix 1 (in both alphabetical order as well as by numeric frequency). Land grant universities dominate. These top 25, all of which are universities, contributed 205 of the 358 articles for which an author’s affiliation was given, or 57.3% of the total. It is clear from these results that land grant universities play a key role in agricultural communication research. Thus, the investment in research at these land grant universities will be a key determinant of future agricultural communication research. However, it is also clear that agricultural communication research is being undertaken by a wide variety of universities and institutions. There are 13 universities that have published 3 articles, another 22 universities (plus the USDA/Washington DC) that have published 2, and 74 more universities, businesses or institutions that have published one. One important implication here for agricultural communicators is that – given the wide dispersion of authors – professional organizations and database providers can play a role in helping bring them together for research purposes. The next step in the analysis was to identify all authors of all the articles. This would permit an examination of how many distinct researchers at each institution have published articles during the 2000-2008 period and how productive they have been. For example, if an article was written by three individuals, two from Auburn University and one from the University of Florida, each of the three would be credited with having published an article in this version of the database. A total of 613 distinct authors were found for the 391 articles, books, and theses/dissertations. Of these, no university or institutional affiliation could be found for 74, leaving 539 that could be included in the database. It should be noted that in order to ascertain the institutional affiliation, often the original article or work had to be located since it was not listed on the abstracting services. Even then, in a number of cases, the journal itself did not include this information. Even without the missing 74 cases, the 539 offer a means of examining the total number of 7

individuals who are involved in agricultural communication research and their locations. A total of 53 of the 539 authors, or about 10%, were found to be ACE members. Table 4 shows the top 25 universities in terms of the number of distinct researchers doing agricultural communication research. Universities at the top of the list might have exceptionally strong agricultural communication research units, or they might have a broader range of different units that contribute collaboratively or separately to the total. Results from the table show that the top 25 universities were responsible for 298 of the 539 articles, or 55.3%. Many of the same universities repeated in the list. Iowa State University ranked first, with 32 separate individuals having authored at least one article during the period. This is due in part to a breadth of interest in communication issues by Extension, Agricultural Education, and Journalism programs. It is also due in part to the fact that multiple authors were often involved in publications from Iowa State, suggesting a collaborate approach. The University of Illinois also ranked higher in Table 4 than in Table 3. The bottom line is that Table 3 shows the overall productivity by institution, while Table 4 shows the number of distinct individuals interested in and participating in the research. Although there clearly is a concentration of researchers at the top 25 universities, most of which are land grant, it is also clear that agricultural communication research is being broadly undertaken by a tremendous variety of universities and institutions. Edgar, Rutherford & Briers (2008) expressed concern about relatively few agricultural communicators trying to do research in numerous research priority areas. The current study suggests that there are a large number of individuals who have done at least some research in this area. Given the large number of different institutions, attention to how to network, collaborate and coordinate activities would seem to be in order. A complete list of all universities/institutions is provided alphabetically and in numerical order in Appendix 2. A separate analysis of the 98 theses/dissertations was also conducted. Table 5 shows the 19 universities that produced at least 2 theses/dissertations matching the search criteria during the 2000-2008 period. The full list of all 52 universities is provided in the appendix. One observation is that academic research in agricultural communication is spread across a very large number of universities. A second observation is that the top 19 accounted for two-thirds of the total. The University of Wisconsin led with 7, followed by Oklahoma State University and Texas A&M University. Table 6 presents the 27 authors who published 3 or more articles contained in the database. One author published 9; one published 7; two published 6; three published 5; four published four; and 16 published 3 articles. Another 49 published 2 articles. The rest, 557 of all 633 total authors, published only one article. These results indicate both the large number of authors publishing, as well as the very small number who are publishing in any quantity in the specific areas included in this database. The field, as Zumalt (2007) noted, is truly scattered. A listing of all authors in alphabetical order with home institutions and departments (if known) is provided in Appendix 3. 8

Conclusions The conclusions here represent only a starting point for the database. The authors invite all agricultural communication researchers to utilize the database and assist in generating insights. • By any measure, the literature of agricultural communication is widely scattered, as observed by Doerfert et al. (2007) and Zumalt (2007). The database for this study found 613 unique authors, 557 of whom have published only one article over the past 8 years. And this database is only a beginning. Jim Evans reports that while 11 ACDC journals that explicitly publish agricultural communication topics were used to build this database, since 2000 the Center has added research articles about agricultural communications from more than 100 journals. The median number of articles in each of these journals relating to agricultural communications was 4. Building this database demonstrates the contribution that the ACDC has made to collecting and making available the literature in this field. Databases such as Communication Abstracts, Agricola, and CABabstracts are missing most of the relevant literature. • Although widely scattered, it is not true as some have suggested that little agricultural communications research is going on. The 391 articles/books/dissertations collected in the current database from 2000 to 2008 represents only a portion of the total, yet it certainly demonstrates a large amount of research activity in this area. Zumalt (2007) reported that the total volume of agricultural communications articles of all types is estimated to be growing at a rate of 14% per year. • The problem, and thus opportunity, is how to help network the diverse group of researchers from 132 universities/institutions who are active researchers in agricultural communications. Networking can be useful for three majors tasks, all of which are important components of the International Framework and Agenda for Agricultural Communications Research. The three are: (1) Literature Review Development. As new issues emerge such as information technologies and biotechnology communication, quick and complete access to published research is vital to focusing scarce research dollars and efforts on priority communication questions. The ACDC has provided a crucial repository for this literature. Perhaps even more efforts to make materials accessible electronically from the database could make its materials even more accessible in the future. (2) Collaborative Research. The current database makes it possible to identify both the individual researchers and the institutions where a specific type of research is being undertaken. This should facilitate the development of multi-institutional multi- disciplinary proposals for research that not only are more rigorous, but also stand a better chance of being funded. (3) Conceptual Development of the Field. Conceptual development can result from an individual study, but more often it is the result of examining patterns of studies over time, and also from considering the many different ideas put forward in published work on a topic. It often is the heterogeneous ideas that come from outside one’s usual university or professional organization that stimulate new ways of thinking. How to facilitate this type of thinking should be an important priority made easier by identifying others from 9

around the country or world who are working on a topic. While the ACDC provides a base, much more effort is needed to mine the database and make conceptual sense of what it means for the field. The current database was designed to provide one more small step in this direction. • The previous studies of the published contents of the Journal of Applied Communications made an important contribution to our understanding of how members of one professional association have focused their research efforts. However, given that ACE members constituted only about 10% of those doing agricultural communication research in the current study, and the fact that ACE members tend to come from certain types of universities with particular interests, it is not surprising that published research from this one journal would not represent the overall stream of research in this field. If one wishes only to summarize efforts of a certain professional group or area, a study of a journal such as JAC would be appropriate. However, if we wish to engage the larger field, future studies should be even more comprehensive than the database constructed for this study. • Faculty or university productivity levels have become a topic of increasing concern over the past decade. The current database provides basic information about which universities are publishing the most articles in the area of agricultural communications, and which authors are publishing the most articles. However, a question remains about what constitutes a significant level of scholarship. Fortunately, scholars in other fields have become interested in this issue as well. For example, a recent leading study in the field of advertising considered publication in the top three journals of the field over a period of about 10 years. Only a small number of authors published three or more articles in the three top journals during this time period, a result very similar to the current study. Before drawing conclusions about what an appropriate number of articles might be, more research and comparison with other fields is needed. • The current database makes it very clear that land grant universities continue to play a key role in agricultural communications research. For this reason, funding for research on agricultural communications will continue to have a great impact on the field, even though there are a wide variety of other researchers and institutions that are involved. Thus, attention to maintaining or increasing funding for research in areas critical to the field deserves systematic attention. From the 1970s through the early 1990s, there was a North Central Regional Communications Committee (NCR-90), that met each year to discuss completed research and to jointly plan research for the coming years. Many ACE members, non-ACE members, and also a number of institutions outside the North Central Region, were members of the committee. This function continues to be needed. While the ACE Research special interest group provides a focus for discussion within ACE, a group with a broader mandate that could interact regularly would also be useful. • The current database offers some specific opportunities for ACE to build up its membership and activities in the area of research. The database identifies by name and institution those who have been active over the past 8 years. These certainly 10

are people who might join ACE, or might participate in research activities in some way in the future. 11
