Revesz, Peter, and Shasha Wu. “Spatiotemporal reasoning about epidemiological data.” Artificial Intelligence In Medicine no. 2 (2006): 157.

Abstract: In this article, we propose new methods to visualize and reason about spatiotemporal epidemiological data. Efficient computerized reasoning about epidemics is important to public health and national security, but it is a difficult task because epidemiological data are usually spatiotemporal, recursive, and fast changing hence hard to handle in traditional relational databases and geographic information systems. We describe the general methods of how to (1) store epidemiological data in constraint databases, (2) handle recursive epidemiological definitions, and (3) efficiently reason about epidemiological data based on recursive and non-recursive Structured Query Language (SQL) queries. We implement a particular epidemiological system called West Nile Virus Information System (WeNiVIS) that enables the visual tracking of and reasoning about the spread of the West Nile Virus (WNV) epidemic in Pennsylvania. In the system, users can do many interesting reasonings based on the spatiotemporal dataset and the recursively defined risk evaluation function through the SQL query interfaces. In this article, the WeNiVIS system is used to visualize and reason about the spread of West Nile Virus in Pennsylvania as a sample application. Beside this particular case, the general methodology used in the implementation of the system is also appropriate for many other applications. Our general solution for reasoning about epidemics and related spatiotemporal phenomena enables one to solve many problems similar to WNV without much modification.

Knight, David A., Robert H. Woods Jr, and Ines W. Jindra. “Gender Differences in the Communication of Christian Conversion Narratives.” Review of Religious Research (2005): 113–134.

Abstract: Scholars have long sought to find the differences in the ways men and women communicate. Also, researchers have studied the field of religious conversion. Thisfirst-of-a-kind study has sought to find if gender differences arise when men and women communicate the story of their religious conversion. Forty structured in-depth interviews with 20 male and 20 female undergraduate students at a small, private Christian liberal arts university in the Midwest were used to address the stated research question. Five male and five females were selected from each grade level. A non-probability sampling procedure was used to select subjects. The final sample consisted of two Hispanics, one Black, and 37 White non-Hispanic participants. The average age of each participant was 20. Although some authors have suggested that conversion stories of men and women would be similar due to a rhythmic narrative formula and common structural elements, this study has found that significant gender differences in the communication of such narratives do arise in certain specific areas. The majority of men used adventurous metaphors, while the majority of women used peaceful metaphors to describe their conversion experiences. It was also found that the majority of men focused on themselves as the control character while most women focused on someone else. And, men described themselves as clever whereas women described themselves as foolish in their narratives.

Abstract: Successful online instructors realize that building a sense of “community” in the online classroom is necessary for successful learning outcomes (Gunawardena, 1994; Wiesenberg & Hutton, 1996; Campbell, 1997; Gunawardena & Zittle, 1997; McLellan, 1999; Kazmer, 2000; Wegerif, 1998). The development of community “becomes a parallel stream to the content being explored” in online courses: [It is not] “something that ‘mucks up’ or interferes with the learning process (Palloff & Pratt, 1999, p. 30).

Abstract: The researcher, an online instructor at the graduate level, considered whether more frequent delivery of instructor-initiated personal (text-only) emails outside of required class discussion formats would result in more favorable student perceptions of the student/faculty relationship, higher student ratings of perceived sense of online community, and a higher degree of satisfaction with the overall learning experience than would less fequent delivery of such instructor-initiated personal emails. The researcher was also interested whether more frequent delivery of personal emails would result in higher levels of student participation in required group discussion formats. Results: regardless of the number of personal emails sent to students throughout the semester, a statistically significant difference between groups could not be identified along the lines of perceived sense of of community, satisfaction with the overall learning experience, or personal relationship with the instructor. More frequent delivery of personalized email did not increase the amount of student participation in required discussion formats. The same positive results were achieved whether the instructor sent two (2) or fifteen (15) personal emails. Explanations for the findings are offered along with suggestions for future research.

Wilhite, David M., and Bruce W. Baldwin. “Triboluminescent Crystals from the Microwave Oven.” Journal of Chemical Education 79, no. 11 (2002): 1344.

Abstract: Anthranilic acid was acetylated in a microwave oven (1,000 W) by irradiating for one minute at full power in a 100 mL beaker fitted with a glass funnel as condenser. After cooling, yellow fluorescing crystals were often obtained; but, if not, recrystallization from 10% water–methanol yielded cubes that fluoresced brightly under 360 nm light. Crushing the crystals between two watch glasses in a darkened room demonstrated the triboluminescent effect (i.e., the production of bright blue sparks when the crystals are fractured).

Ebersole, Samuel E., and Robert Woods. “Virtual Community: Koinonia or Compromise?-Theological Implications of Community in Cyberspace.” Christian Scholars Review 31, no. 2 (2001): 185–216.

Abstract: With the growth of computer-mediated communication and the rise of virtual communities, theological issues relating to the nature of these relationships must be addressed. The authors first define community and then explore recent trends in online communities. The discussion of virtual community and new media technologies is grounded in a historical context focusing on the introduction of the telegraph and radio broadcasting. Buber’s dialogic communication is proposed as a normative base for community in light of the interpersonal character of online community. And finally, six virtues of community are discussed in light of the technologies and practices of online community.
