Recycling: Knowledge, Demographic & Motivational Factors Which Differentiate Behavior

This study focuses on motivation -Involved in recycling behavior among residents of Muhlenberg County, Kentucky. Knowledge of recycling and how it was acquired, and the variables of environmental concern, economic incentive and the peer pressure were compared so that behavior could be distinguished that separated recyclers from nonrecyclers. Talcott Parsons\u27 work in action theory and George Homans\u27 work in exchange theory provide the theoretical foundation for my study. The research was approached in a qualitatively based design with interviews of twenty area residents. Demographic factors of age, sex, religious affiliation, church attendance, education and income of respondents were solicited. In addition to interviews, I administered a demographic survey. Recycling behavior was correlated positively with older age, convenience, female sex, higher levels of education, higher income, affiliation with liberal church denominations, and urban residence. It was negativley correlated with church attendance. Recyclers were better informed about environmental topics, especially those pertaining to recycling. Peer pressure was shown to have a positive effect on recyclers and recycling behavior. Recyclers were concerned about the quality of their environment, while nonrecyclers felt that the quality of the local environment was above average

Experimental and mathematical modeling studies of protozoan predation on bacteria

The predation of bacteria by protozoan in both continuous and batch cultures was studied using experimental and modeling techniques. The predator organism was the ciliate, Tetrahymena pyriformis. The bacterium, Aerobacter aerogenes , served as the prey. Several batch growth responses were observed each initiated at a different nutrient level. Continuous cultures were conducted over a range of dilution rates. The models studied were partially successful in simulating the empirical data. Deviations between the model and the actual population behavior are discussed and possible explanations for the differences proposed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37882/1/260150406_ftp.pd

Real-time phase-contrast x-ray imaging: a new technique for the study of animal form and function

BACKGROUND: Despite advances in imaging techniques, real-time visualization of the structure and dynamics of tissues and organs inside small living animals has remained elusive. Recently, we have been using synchrotron x-rays to visualize the internal anatomy of millimeter-sized opaque, living animals. This technique takes advantage of partially-coherent x-rays and diffraction to enable clear visualization of internal soft tissue not viewable via conventional absorption radiography. However, because higher quality images require greater x-ray fluxes, there exists an inherent tradeoff between image quality and tissue damage. RESULTS: We evaluated the tradeoff between image quality and harm to the animal by determining the impact of targeted synchrotron x-rays on insect physiology, behavior and survival. Using 25 keV x-rays at a flux density of 80 μW/mm(-2), high quality video-rate images can be obtained without major detrimental effects on the insects for multiple minutes, a duration sufficient for many physiological studies. At this setting, insects do not heat up. Additionally, we demonstrate the range of uses of synchrotron phase-contrast imaging by showing high-resolution images of internal anatomy and observations of labeled food movement during ingestion and digestion. CONCLUSION: Synchrotron x-ray phase contrast imaging has the potential to revolutionize the study of physiology and internal biomechanics in small animals. This is the only generally applicable technique that has the necessary spatial and temporal resolutions, penetrating power, and sensitivity to soft tissue that is required to visualize the internal physiology of living animals on the scale from millimeters to microns
