Academic And Social Experiences Of Female Community College Transfer Students In Engineering Fields At Midwestern University, Darryle D. Bohanna Jan 2016

Academic And Social Experiences Of Female Community College Transfer Students In Engineering Fields At Midwestern University, Darryle D. Bohanna

Graduate Theses and Dissertations

Currently, there remains a shortage of women in science, technology, engineering and mathematics (STEM) fields despite recent efforts to increase numbers. The Department of Commerce is predicting that STEM job openings will grow 17% by 2018, which is a much faster rate than most other careers. These are among the highest-paying fields, in part because of the rising demand. Educational institutions in the United States will have to address this issue in order to compete economic leadership globally. High schools, community colleges, and four year institutions must increase awareness and efforts to recruit and retain more women in STEM majors ...


Investigating The Use Of In Situ Liquid Cell Scanning Transmission Electron Microscopy To Explore Dna-Mediated Gold Nanoparticle Growth, Amanda Nguy Jan 2015

Investigating The Use Of In Situ Liquid Cell Scanning Transmission Electron Microscopy To Explore Dna-Mediated Gold Nanoparticle Growth, Amanda Nguy

Graduate Theses and Dissertations

Engineering nanoparticles with desired shape-dependent properties is the key to many applications in nanotechnology. Although many synthetic procedures exist to produce anisotropic gold nanoparticles, the dynamics of growth are typically unknown or hypothetical. In the case of seed-mediated growth in the presence of DNA into anisotropic nanoparticles, it is not known exactly how DNA directs growth into specific morphologies. A series of preliminary experiments were carried out to contribute to the investigation of the possible mechanism of DNA-mediated growth of gold nanoprisms into gold nanostars using liquid cell scanning transmission electron microscopy (STEM). Imaging in the liquid phase was achieved ...


Algae: Opportunities For Biomass Feedstock Production, Wastewater Treatment And Educational Outreach, Trina Cassandra Halfhide May 2014

Algae: Opportunities For Biomass Feedstock Production, Wastewater Treatment And Educational Outreach, Trina Cassandra Halfhide

Graduate Theses and Dissertations

Algae are a diverse group of simple organisms that lack roots, stems or leaves and are able to use sunlight, carbon dioxide, and nutrients to produce complex compounds, such as carbohydrates, proteins and lipids. These compounds, especially lipids, are highly sought-after by agricultural, nutraceutical and energy interests. Although there is great potential for algae derived biofuels, there are technical and economic challenges associated with their cultivation. Relevant to this dissertation, the environmental impacts associated with algae cultivation can be reduced by using municipal and agricultural wastewaters as a water and nutrient source. This research was divided into three sections to ...


Academic And Social Integration Variables Influencing The Success Of Community College Transfer Students In Undergraduate Engineering Programs, Marcia Rae Laugerman Jan 2012

Academic And Social Integration Variables Influencing The Success Of Community College Transfer Students In Undergraduate Engineering Programs, Marcia Rae Laugerman

Graduate Theses and Dissertations

ABSTRACT

The goal of this dissertation is to collect and analyze data to determine success strategies for community college (CC) transfers to engineering. It does so by analyzing transcript level data collected longitudinally over a 10-year period as community college transfer students' progress before and after transfer into an engineering program. Characteristics of successful students are identified in terms of the academic and social integration variables using descriptive and inferential statistics. In addition to providing data analysis, the results determine distinctive strategies to increase the success of community college transfers in engineering.

The research was funded by the National Science ...
