Zoos, aquariums and other free-choice/informal education settings offer the public opportunities to interact with live animals in exhibits through animal encounters and/or touch experiences designed to carry a conservation mission. Many of these institutions are accredited by the American Association of Zoos and Aquariums (AZA) and the World Association of...
There is growing evidence that children develop science-related interests in early childhood, before they enter school, and that these interests may have long-term implications for science participation and achievement. Although researchers have made headway in describing interest development in the preschool years, little is currently known about the proximal processes...
The natural environment provides important services and benefits to peoples’ health and lives. Conversely, environmental disservices can have negative impacts on humans such as through pollution, chemical toxins, and climate change. The combination of environmental services and disservices encompass how human health and wellbeing, and the environment are connected. As...
Watershed analysis is a method used to collectively characterize ecosystem elements present within a watershed. Wastewater flow and pollutant content help to define the appropriate wastewater treatment system necessary to treat the wastewater within the watershed. Watershed monitoring aids to investigate the potential contamination through analysis of surface waterbodies. Major...
The persistent underrepresentation and marginalization of women of color in the disciplines of science, technology, engineering, and mathematics (STEM) are well-documented. However, much of the existing literature takes an “either/or” approach, focusing solely on the experiences of either “women” or “minorities” in STEM, without adequately examining the unique experiences of...
The consumption of alcohol has been shown to have effects on health that are both harmful and
therapeutic, depending on the amount that is consumed. Alcohol’s effects can be damaging to the body in excess but, in moderation, can act as a protectant against certain conditions. The two studies discussed...
Two experiments were conducted to evaluate the effects of
gonadotropin releasing hormone (GnRH) on the function of the bovine
corpus luteum during the estrous cycle. In Experiment 1, 10 heifers
were assigned randomly into two groups with each heifer serving as
her own control. Heifers in Group I (n=5) were...
There are a nearly unlimited number of situations in which the
status of time-varying processes must be updated. The monitoring of
these processes usually occurs at periodic intervals. Whether the
monitoring is performed by man or machine, a decision must be made
regarding the frequency of these activities, that is,...
The structure of the nucleoprotein core of adenovirus has been
investigated. Using a combination of biophysical techniques and
nuclease digestion I have determined that the adenovirus core, as
isolated with pyridine, shares several physical properties with cellular
chromatin. The most notable difference is the lack of a nucleosome
repeat in...
