There exists in our profession a persistent shortage of quality teachers in our high school agricultural education classrooms. A multitude of studies have identified challenges faced by agriculture teachers, however, few, if any, have investigated reasons for attrition by directly asking leavers why they left. This study sought to identify reasons for leaving the profession as perceived by former high school agriculture teachers. Nine former secondary agriculture teachers were interviewed. Themes emerging from this qualitative case study include 1) passions for the profession, 2) alternative opportunities, 3) expectations, 4) burdens, retrospectively and 5) people. Teachers were passionate about their students, their content area and competition inherent in agricultural education. All of the participants had chosen to accept alternative employment opportunities. Former teachers recalled having high expectations for themselves and their career, and perceiving others to have high expectations as well. The teachers recalled the burdens of their job retrospectively, and people played an integral role in their career as well as their decision to leave the profession. Former teachers were satisfied while teaching, but found greater benefit in alternative opportunities. Recommendations include encouraging realistic expectations, developing mentor programs for novice teachers, and strengthening the benefits of remaining in the profession.

Research was conducted to determine response rates and response reliability between three modes of survey techniques. Random samples of Texas Agri-Science teachers were surveyed using an e-mail instrument, a web-based instrument, and a traditional paper instrument. Responses among each mode were compared to determine if the mode of survey has an impact on the data collected. Response rates for each mode were also determined and compared. Researchers found that while there were no significant differences in reliability of responses, there were significant differences in response rates based on mode of collection. Traditional paper surveys yielded the high response rate at 60% with a significant drop to the web surveys at 43%, along with another significant decline to the e-mail surveys at 27%. The researchers propose a bi-modal method of data collection to minimize costs and time. Using data collected from this study, the researchers advocate a 25-day model of five individual contacts beginning with e-mail notifications of web surveys and concluding with follow-ups using traditional paper instruments. Further testing of this bi-modal survey model is encouraged. Other populations should be tested in order to add to the knowledge base in this increasingly important field.

Microwaves have been shown to cause thermal as well as nonthermal destruction of pathogens such as Salmonella Enteritidis, which is commonly found in shell eggs. The objective of this study was to examine the use of new directional microwave technology to reduce Salmonella Enteritidis without causing any detrimental effects on quality in white and brown eggs. Treatments were control and microwaved white and brown eggs. Applying directional microwave technology resulted in a 2-log reduction of Salmonella Enteritidis in both the high (10(5) cfu/g) and low (10(2) cfu/g) inoculum. At d 0, there were no differences in water activities, albumen pH, and combined pH between treatments; however, there were significant changes in yolk pH. Collectively, these results indicate that applying directional microwave technology can reduce Salmonella Enteritidis in shell eggs without causing any detrimental effects to quality.

Global trends are demanding agricultural students have a broader perspective of agriculture and competitiveness and they become responsible global citizens. This study compared United States and Latin American undergraduate students' knowledge, attitudes, and beliefs regarding international agricultural issues, as well as their attitudes about global citizenship. Overall, students' results indicated a lack of knowledge regarding international agricultural issues, with only 3.6% obtaining a score above 60%. Students' recorded positive attitudes and beliefs about international agricultural issues but had mixed feelings regarding global citizenship attitudes. Scores on all constructs were found to be significantly different between the studied academic institutions (p < .05). The stepwise multiple linear regression indicated the predictors of university of enrollment and students' attitudes and beliefs about international agricultural issues were significantly related to their global citizenship attitudes: F (3, 1194) = 83.04, p = .01, explaining 17% of the variance in the model. The obtained results suggest students hold positive and open-minded attitudes and beliefs regarding international agricultural issues. These attitudes should be balanced by academic institutions with the knowledge needed by students to meet the demands of the agricultural industry. A global understanding can potentially enable future professionals to succeed in both local and global settings, and furthermore, help them become global citizens.

Meals ready-to-eat (MRE) are self-contained and flexible packages used by military personnel while in the field to store food for an extended period of time; however, inclusion of white bread is not a common practice because of short shelf life stability and spoilage. The objective of this study was to determine mold inhibition and quality attributes over a 60-d period after applying directional microwaves. Different bread loaves were used for quality and for microbiological experiments. For microbiological analysis, bread was exposed to 0-, 5-, 6-, 7-, 8-, 9-, and 10-s directional microwave treatments after inoculation with a 3 strain cocktail of common bread mold, stored at 25 degrees C for 60 d, and monitored for mold growth. For quality analysis, bread was exposed to 0- and 10-s treatments, stored at 25 degrees C, and moisture, water activity (a(w)), softness, and sensory analysis were analyzed on 0, 7, 14, 28, 45, and 60 d. There was no quantifiable mold present at day 0 when treated for 10 s (P < 0.05). By day 60, the 10-s treatment had significantly lower counts (< 3 CFU/g) than the remaining treatments. Directional microwave treatment significantly decreased the moisture content of the bread but was not detectable by consumers. There was no difference in a(w) through day 45 but differences were detected at day 60. There were no differences in softness (mm) of the treated and untreated bread through day 60. No differences were detected by sensory analysis. Directional microwaves can be used to extend the shelf life of white enriched bread up 2 mo with minimal mold growth and without detrimental effect to quality.
