"Static Formations Using Momentum Exchange Between Satellites."
Journal of Applied Developmental Psychology, 32(4): 1277 - 1286. (2009)
Prof. Steve Tragesser, Department of Mechanical and Aerospace Engineering
Article's Abstract
"Feasible operations of satellite formations are dependent upon an efficient way to affect the relative motion. One possible means of formation stationkeeping is for satellites to exchange momentum in the form of radiation or mass. This approach could potentially provide a mutually repulsive force between satellites without the expenditure of propellant. This paper characterizes equilibria positions in the rotating orbital frame for an arbitrary number of satellites subjected to equal and opposite repulsive force between specifiable satellite pairs. Equilibrium configurations are found that allow arbitrary dispersion in the plane perpendicular to nadir. Stability analysis of these equilibria show stable out-of-plane motion and unstable in-plane motion. A strategy is developed to stabilize the system and to reconfigure the formation geometry. Finally, a simulation including Earth oblateness demonstrates the dynamic feasibility of this method of orbit control." -- Abstract by author.

"Racial/ethnic Group and Socioeconomic Status Variation in Educational and Occupational Expectations from Adolescence to Adulthood."
Journal of Applied Developmental Psychology, 30(4): 494 - 504. (2009)
Prof. Zena Mello, Department of Psychology
Article's Abstract
"This longitudinal study examined the development of educational and occupational expectations from adolescence to adulthood in relation to racial/ethnic and socioeconomic status (SES) group membership. Hierarchical linear modeling on national data (NELS:88) spanning 12 years yielded several findings: (a) African American participants reported the highest educational expectations, followed by Hispanic and Asian American/Pacific Islander, European American, and American Indian/Alaskan Native participants, (b) African American and Asian American/Pacific Islander participants reported the highest occupational expectations, followed by Hispanic, American Indian/Alaskan Native, and European American participants, (c) racial/ethnic group patterns persisted from adolescence to adulthood, and (d) SES positively predicted expectations. Results highlight the importance of considering SES when examining educational and occupational expectations across racial/ethnic groups." -- Abstract by author.

"Transatlantic Food Fights in an Era of Globalization: When Menus, Rules and Choices Collide" in
Transatlantic Environment and Energy Politics. Miranda Schreurs, Henrik Selin and Stacy Vandeveer eds., Ashgate Press: Burlington, VT. (2009)
Prof. Patricia Keilbach, Political Science Department
Book Description
"Environmental and energy policies have become increasingly significant in European and North American politics. This fascinating book uses a wide range of case studies that embrace climate change, product standards, chemical regulations, renewable energy policies, food safety and genetically-modified organisms to examine areas of conflict and cooperation in the transatlantic relationship.
"While there are many areas where the European Union and the United States are following divergent policy paths, there are also many signs that a more cooperative transatlantic relationship could emerge in the future. Transatlantic Environment and Energy Politics is highly relevant to understanding how the European Union and North America can cooperate more effectively in meeting today's many global environmental and energy policy challenges. It is essential reading for all advanced students and scholars." -- back of book.

Quantitative analysis of tetramethylenedisulfotetramine (tetramine) spiked into beverages by liquid chromatography-tandem mass spectrometry with validation by gas chromatography-mass spectrometry.
Journal of Agricultural and Food Chemistry, 57(10): 4058-4067. (2009)
Prof. Janel Owens, Department of Chemistry
Article's Abstract
"Tetramethylenedisulfotetramine, commonly known as tetramine, is a highly neurotoxic rodenticide (human oral LD50 = 0.1 mg/kg) used in hundreds of deliberate and accidental food poisoning events in China. This paper describes a method for the quantitation of tetramine spiked into beverages, including milk, juice, tea, cola, and water, with cleanup by C8 solid phase extraction and liquid-liquid extraction. Quantitation by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was based upon fragmentation of m/z 347 to m/z 268. The method was validated by gas chromatography-mass spectrometry (GC-MS) operated in selected ion monitoring mode for ions m/z 212, 240, and 360. The limit of quantitation was 0.10 μg/mL by LC-MS/MS versus 0.15 μg/mL for GC-MS. Fortifications of the beverages at 2.5 and 0.25 μg/mL were recovered ranging from 73 to 128% by liquid-liquid extraction for GC-MS analysis, from 13 to 96% by SPE, and from 10 to 101% by liquid-liquid extraction for LC-MS/MS analysis." -- Abstract from journal.

"Eschewing Sexual Agency: A gender Subjectivity Approach."
Race, Gender and Class, 16(1/2): 102 - 132. (2009)
Prof. Heather Albanesi, Department of Sociology
Article's Abstract
"This article argues for the utility of psychoanalytic theory within the sociology of gender for exploring subjective meaning. Using data drawn from indepth interviews of 83 heterosexual young men and women, the author connects the degree to which the subject expresses agency within sexual encounters to their subjective experience of gender-that is, to the specific meaning (including raced and classed meaning) and dominant emotions (conscious and unconscious) that the subject attributes to masculinity and femininity. This article presents an analysis of two cases selected from the larger study representing the subset of subjects that avoid expressing sexual agency." -- Abstract from Ethnic NewsWatch database.
