Critical point wetting drop tower experiment

Preliminary results for the Critical Point Wetting CPW Drop Tower Experiment are produced with immiscible systems. Much of the observed phenomena conformed to the anticipated behavior. More drops will be needed to test the CPW theory with these immiscible systems

Bridging Alone: Religious Conservatism, Marital Homogamy, and Voluntary Association Membership

This study characterizes social insularity of religiously conservative American married couples by examining patterns of voluntary associationmembership. Constructing a dataset of 3938 marital dyads from the second wave of the National Survey of Families and Households, the author investigates whether conservative religious homogamy encourages membership in religious voluntary groups and discourages membership in secular voluntary groups. Results indicate that couples’ shared affiliation with conservative denominations, paired with beliefs in biblical authority and inerrancy, increases the likelihood of religious group membership for husbands and wives and reduces the likelihood of secular group membership for wives, but not for husbands. The social insularity of conservative religious groups appears to be reinforced by homogamy—particularly by wives who share faith with husbands

Children, civilianhood, and humanitarian securitization

In this paper, the influence of the construction of children as civilians over the processes of securitization in the US intervention in Somalia is examined. This is done through an analysis of the US print news media coverage of that event. The study employs two key theoretical frameworks: the first is the social understanding of civilianhood; and the second is the Copenhagen School’s theory of securitization. The work concludes that a failure to unpack the value of referent objects of security diminishes the insights that securitization theory can offer. The grammar of securitizing moves cannot be fully comprehended in instances of militarized humanitarian interventions, in particular, without this kind of analysis. Children as suffering civilians draw considerable attention from the world’s media and thus an investigation of their role in securitization can be highly informative

Activities-based Astronomy: An Evaluation of an Instructor’s First Attempt and its Impact on Student Characteristics

This study assessed the effectiveness of an instructor’s first attempt at an activities-based, non-majors astronomy course. Although students in this course performed as well as those in a lecture-based course, students in the activity-based course had a significant reduction in their self-efficacy with regard to science. Findings suggest that activities were most effective when they helped students to visualize spatial relationships, provided equal opportunity for engagement, and were clearly related to course content. However, activities often led to student confusion regarding the relevancy of activities to course content, the importance of information presented, and the connection between class and textbook information

Educational Research in an Introductory Astronomy Course

The lecture is a common method used in college instruction, but many teachers are questioning its effectiveness. For this study, two successive spring semester sections of introductory astronomy for non-science majors were studied. The spring 1999 semester was the instructor’s first attempt to incorporate innovative instructional techniques to include “hands-on, minds-on” instruction within the lecture setting. The educational research involved classroom observations, personal interviews, and pre-instruction/post-instruction administration of the Texas Attitude Survey and the Astronomy Diagnostic Test. During the spring 2000 semester, the instructor modified instruction to respond to student concerns from the previous semester. Student scores for the second course showed significant improvement in astronomy content and the institutional course survey, but not in student self-efficacy
