old mice were compared. The purpose of this research was to identify genes that are
differentially regulated due to aging. The results showed 148 significantly differentiated
genes in the analysis of a total of 44,170...
Crime rates affect everything from home values, to the quality of education. Through the use of Social Disorganization Theory this paper will support the hypothesis that there is a correlation between neighborhood upkeep and crime rates within neighborhoods. Social Disorganization theory itself aims to show the correlation between the place...
In society, labeling can play an important role in how people interact with one another every day. This research focuses on the relationship between internalization and deviance, two important concepts in Labeling Theory. The main question is, does the internalization of a label play a role, whether it be positive...
This manuscript seeks to draw inferences from an amalgamation of research done regarding types of conflict and their effect on the performance of small groups. The effects of conflict and cohesion on mediating leadership are also examined, with the intention of illuminating conflict management strategies that can be used by...
There are record numbers of immigrants in the U.S., with no indication of declining in the future. Social debates surrounding issues such as immigration are fragile.

Most animals are active either during the day, night, or twilight, and transition periods between these times exhibit interesting behavior. Actions may be related to avoiding predators, seeking shelter, defending territory, feeding, or other interests. Herbivorous fishes on coral reefs, such as parrotfishes, forage constantly throughout daylight periods due to...
Sea stars are well known on the Pacific coast as being keystone species. Pisaster ochraceus plays a major role in controlling the lower limits of the high zone mussel beds, normally preying on medium to large-sized species. Leptasterias hexactis is often found feeding on smaller prey. According to the competitive...
The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...
It has been observed and documented that Pisaster ochraceus has very striking colors, but the reasons behind the coloration are still unknown. Three coloration categories were determined and used for a feeding trial study to investigate the effects of diet on coloration in Pisaster ochraceus. This study involved 30 hand...
