Strong self-regulation in early childhood is a key predictor of academic and social success from elementary school through college (McClelland et al., 2012). This study analyzed the influence of the age of the child’s parent on the child’s self-regulation as measured by the HTKS (Head-Toes-Knees-Shoulders) measure. Relations between children’s self-regulation...
Pisaster ochraceus occurs in a variety of colors; the major hues being orange, brown, and purple. Harley et al. (2006) found that in areas on the open Pacific coast, where Mytilus californianus was present, less than 10% of the population of P. ochraceus were purple whereas in areas of the...
Oxytocin was confirmed to have an impact of the PIP2 breakdown in ovine endometrial tissue. This experiment took two groups of ovariectomized ewes (n=5) and administered a shortened estrus cycle hormone regiment. It was found that, independent of the hormone treatments, especially P4, OT caused a small increase in the...
Accurate diagnosis is the most important step in identifying and curing diseases. There are no accurate low cost disease diagnostic tools available for developing countries. The use of microfluidic paper-based analytical devices and colorimetric analysis of an assay response could solve these issues. Several colorimetric liver assays have been demonstrated...
HafSOx is a dielectric material that also functions as an insulator. It is able to be
spin-coated onto a silicon substrate, creating a thin, amorphous film. It is very dense, which helps lead it to a high dielectric constant, making it ideal for electronic devices through the use of lithography....

The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...
We found that a strains of Yersinia pestis (KIM5) which lacked the nhaA gene was fully attenuated in a plague model. This gene produces a protein of the sodium-proton antiporter family which expel sodium ions from the bacterial cytoplasm in exchange for hydrogen ions, or protons, from the surrounding environment....
The overall objective of this research was to determine which, if any, myosin XI proteins and exocyst proteins play a role in growth of Arabidopsis thaliana hypocotyls and root hairs. This involved the study of whether exocyst and myosin proteins work together during cell expansion within these two plant parts....
This paper will focus on the relationship between institutional internalization and organic solidarity. Being that there is a wide verity of different institutions, this writing will focus primarily on only religion, politics, and education. The internalization of the individual from each of these institutions greatly effects their beliefs, desires, and...

Prostate cancer is one of the most prevalent types of cancer in the U.S. and is among the leading causes of death in men of all races. One predictor of advanced prostate cancer and aggressive tumor behavior is the overexpression of the histone methyl transferase EZH2.
EZH2 functions in the...
Climate change is a hot potato policy: the responsibility for it is constantly passed between the domestic and international realms. By definition global climate change is a global problem yet, in the US, domestic concerns are preventing federal lawmakers from taking action and presidents from taking leadership at both the...
According to recent research, children’s learning related skills, such as cooperation, self-regulation, responsibility, and independence, are closely related to their academic outcomes (McClelland, Acock, Morrison 2006). While self regulation during preschool and it’s related skills are predictors of later academic achievement, it might be beneficial to determine a simple screening...
Lien, Ruthruff, and Johnston (2010) reported that the attentional control system is able to rapidly and fully switch between different search settings (e.g., red to green), with no carryover. The present study examined whether such impressive flexibility is possible even with more complicated switches, namely singleton search and the feature...
The present study examined whether semantic activation for words occurs by encoding whole word shape in addition to individual letters. We used LEET stimuli, where digits were used as parts of words, such as “R34DING” instead of “READING”. Previous studies have suggested that LEET stimuli are encoded in a letter-like...
Phylogenic studies suggest that cells from long-lived species are more resistant to a variety of stressors than short-lived species. However, there is little information on the cellular mechanisms that give rise to increased resistance to stress. Our previous studies have shown that liver proteins from a long-lived species have lower...
In this study, the gene expression levels between 6 month old mice and 26 month
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...
Oregon serves as an interesting case study for the success of feminist mobilization in the 1970s, yet demonstrates how legislation did not immediately change society’s deep rooted assumptions about gender, family roles, and sexual violence.
The presence of nitrates and nitrites in food is associated with an increased risk of gastrointestinal cancer and, in infants, methemoglobinemia. Nitrites are produced endogenously through the oxidation of nitric oxide and through a reduction of nitrate by commensal bacteria in the mouth and gastrointestinal tract. Despite the physiologic roles...
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...
