16 pages., Via online journal., Expertise is dynamic, domain specific, and characterized according to an individual’s level of knowledge, experience, and problem-solving ability. Having expertise in the phenomenon under investigation can be used as an indicator of an individual’s aptitude to effectively serve as a coder in a content analysis or as panelist in a Delphi study. The purpose of this study was to assess 10 years of scholarship published in the premier journals of agricultural education and describe the ways researchers in agricultural communications, education, extension, and leadership disciplines who use content analysis and Delphi study methods are describing the qualifications of the people serving as expert coders and panelists. The study findings revealed the majority of researchers publishing in the premier agricultural education journals are not describing the qualifications used in selecting coders or the credentials the coders possess that would make them qualified to code the data in a content analysis. Furthermore, researchers were inconsistent citing literature that supported their selection of content analysis coders and citing literature to support a decision to describe or not to describe coders’ qualifications. However, a description of Delphi study panelists’ qualifications and citations to support why panelists were selected in a Delphi study were present in all of the Delphi studies analyzed over the 10-year period. Based on these findings, it was concluded that ACEEL researchers should include a description of coder credentials to enhance the consistency, transparency, replicability, rigor, and integrity of ACEEL research. Editors and research professionals who perform journal article reviews for the premier agricultural education journals are encouraged to note the exclusion of a description of content analysis coders’ credentials as part of the peer review process.

Notes:
20 pages., Via online - Power Point presentation. Summarizes retail dealers' adoption of precision technologies in agriculture, 1997-2017., The CropLife/Purdue University precision dealer survey is the longest-running continuous survey of precision farming adoption. The 2017 survey is the 18th, conducted every year from 1997 to 2009, and then every other year following. Major sections of the survey include precision technologies used by the retailers within their business/on their equipment, the adoption rates of precision products and services offered by retailers to customers, the dealer’s estimation of the acres in their area where farmers are using precision practices, and questions about profitability, technology investment, and constraints to adoption.
The 2017 survey shows substantial increases in the adoption of practices that provide data for understanding and managing inter- and intra-field variability. Grid/zone soil sampling, which was being offered by 35 to 57% of dealers in a period stretching from 1999 to 2013, increased to 67% in 2015 and to 78% offering in 2017. Soil EC mapping increased from 19% in 2015 to 31% in 2017, and dealers offering UAV services from 19% to 30%. At the same time variable rate technology (VRT) seeding prescriptions, VRT lime application, and VRT fertilizer application services are up, yet VRT pesticide offerings are down. Seventy eight percent of dealers are using autoguidance for their custom application and 73% are using sprayer section controllers.
