Viruses consist of nucleic acid packaged in a protective shell composed of protein or, in some cases, protein plus lipid. This shell protects the nucleic acid from enzymatic degradation while it is outside the host cell in a potentially hostile environment. Recent advances in virus detection and diagnosis are based on increased sensitivity of methods for the detection of proteins and nucleic acids.
The Pennsylvania State University Medieval Garden (PSMG) showcases varieties of medieval plants used as ornamentals, food crops, medicinal ingredients, and for household purposes in a stylized setting representing a medieval garden. Since its installation, various colleges within the university as well as community groups have used the garden as an alternative classroom for learning activities, educational demonstrations, and events related to the medieval period. This article focuses on the initial development of the garden design and how the installation and continued use as a classroom has contributed to meeting educational goals for students in the landscape contracting program at the Pennsylvania State University and the Pennsylvania Governor's School for Agricultural Sciences.
Globalization affects many aspects of American society, including higher education. Many institutions of higher education realize the need to help students become global citizens and thus require an international perspectives course as part of their undergraduate curriculum. The goal of this research was to evaluate the Horticulture Travel Course (Hort 496), which includes an international travel component, to determine whether it meets the university and College of Agriculture's expected learning outcomes and competencies in international and multicultural awareness. A 23-question survey instrument consisting of open- and close-ended questions was mailed to 116 former Hort 496 participants. Forty-three percent of the questionnaires were returned and were usable. Survey questions were designed to gather information on student demographics, previous international travel experience, learning outcomes achieved through participation in the pretrip preparatory class and the study abroad experience, and how these experiences influenced career development. Responses indicate that both the pretrip preparatory class and study abroad experience helped participants achieve the course learning outcomes. Furthermore, student presentations and guest speakers, and interacting with locals and planned tours immersed students the most in the pretrip preparatory class and study abroad experience, respectively. A majority of participants observed recognizable differences in agricultural management or production practices between the United States and the country visited. Participants also noted that Hort 496 had a positive affect on their communication skills, interpersonal skills, and personal growth.
