In order to enhance Extension evaluation efforts it is important to understand current practices. The study reported here researched the evaluation behaviors of county-based Extension professionals. Extension professionals from eight states (n = 1,173) responded to a survey regarding their evaluation data collection, analysis, and reporting methods while evaluating their "best" Extension program. The majority used post-tests at the conclusion of their educational activities and reported the actual numbers of respondents. Few respondents collected data representing behavior change. To improve, Extension professionals need to gain evaluation skills and work together to develop strong evaluations that measure change over time.

As part of a larger project to show how fresh fruits and vegetables with enhanced flavor can be successfully handled to improve consumer satisfaction without compromising food safety, key informant interviews were conducted with fruit industry leaders dealing with melons ( Cucumis melo and Citrullus lanatus ), peaches and nectarines ( Prunus persica ), pears ( Pyrus communis ), tomatoes ( Solanum lycopersicum ), strawberries ( Fragaria × ananassa ), and blueberries ( Vaccinium sp.). The interview was designed to collect information on industry attitudes and practices related to postharvest handling of more mature fruit, harvest timing, preconditioning, cold chain management, and shipping and handling procedures throughout the supply chain. The current analysis focuses on two key questions from the interviews: 1) To what extent do industry experts believe that better fruit handling and shipping procedures contribute to better taste quality in fruit? 2) To what extent do industry experts believe that better fruit quality will lead to more consumer purchasing? In response to the first question, the majority of respondents (70%) agreed that postharvest handling affects fruit flavor with the most cited themes related to agreement being gentle handling, cold chain management, and harvest timing. Of the respondents who expressed disagreement most acknowledged the importance of postharvest handling, but felt other factors were also important, mainly the variety grown, the shelf life requirements, and the growing conditions. For the second question, 95% of respondents agreed that increased taste quality of fruit would mean increased purchasing and consumption. The primary theme related to agreement was that consumers would repeat purchase after positive eating experiences. Other important factors were the price point of fruit, retail display, product identity, and fruit appearance. With increasing consumer attention to fruit quality and a generally accepted belief among industry representatives that fruit flavor and quality drives consumer demand, there is an opportunity to shift industry practices toward postharvest handing that is conducive to consistently delivering better-tasting fruit to consumers.

This article uses a systems-thinking framework to analyze Puerto Rico’s solid waste system. Our findings were based on 36 semi-structured interviews from stakeholders that work within the solid waste system. Interviewees represented businesses, advocacy organizations, a university, and government agencies, including municipal, central, and federal government. This research is unique because it focuses on a case study using a historical lens to explore the policies and stakeholder dynamics that shape a system’s behavior, where the behavior is in reference to the flows of discarded materials either entering the circular economy or the island’s waste disposal facilities. Through our research, we found that Puerto Rico’s overall solid waste system is stalled within a balancing feedback loop where policies and dynamics have taken place that have created resistance to efforts to improve the current situation. In our discussion, we reflect on the policies and stakeholder dynamics that have caused this balancing feedback loop and make recommendations to better support a reinforcing feedback loop that will lead to changes to achieve Puerto Rico’s solid waste disposal and recycling plans and goals required to foster a circular economy. This study can inform future policy making and institutional coordination efforts within Puerto Rico and abroad.

To explore Extension professionals' perceptions of the potential impact of climate variability and climate change on agriculture and to identify the top climate-related issues facing farmers, we conducted interviews with agricultural Extension personnel from Alabama, Florida, Georgia, and South Carolina. Of those interviewed, 92% believed climate change will affect agriculture a moderate amount or a great deal. Qualitative analyses revealed that the Extension professionals considered scarcity of water resources, temperature fluctuations, pest and disease pressures, forecast challenges, seasonal variability, and adaptation strategies as among the most important climate-related issues affecting agriculture in the Southeast.
