An analysis of stereotype threat in African American engineering students at predominantly White, ethnically diverse, and historically Black colleges and universities

NASA Astrophysics Data System (ADS)

Sparks, David M.

The purpose of this research was to distinguish the similarities and differences in coping strategies of African American engineering students by analyzing their perceptions of stereotype threat at three academic institution types, Predominantly White Institutions (PWI), ethnically diverse, and Historically Black Colleges and Universities (HBCUs). The researcher collected demographic and survey data using the Stereotype Vulnerability Scale (SVS). The study was offered to the entire population of African American engineering students at each college using an online survey. Results were analyzed using MANOVA and Pearson's correlational statistical analyses to test the hypotheses. Findings revealed that little differences exist between students' scores on an assessment of stereotype vulnerability, with a few areas showing that HBCUs and ethnically diverse universities are doing a similar job in addressing perceptions of their African American engineering students. Finding also revealed that the percentage of African American students at a university did not correlate with the scores on the SVS accept on questions related to the personal feelings students have about their race. The strongest findings related to the differences in male and female students across the universities. African American female engineering students appeared to perceive more stereotype threat than did their male counterparts; although, this fining was not statistically significant. Overall, no statistically significant differences were found between students' perceptions of stereotype threat at the three types of universities. Future research should expand the number of survey participants at the current universities, add more HBCUs to the study population, run similar experiments in different parts of the country, compare stereotype threat in private and elite universities, use ethnically diverse universities as models for minority student development, and use new or improved survey instruments that delineate race and gender stereotype threat as perceived by African American female STEM students.

Evaluating North American Electric Grid Reliability Using the Barabasi-Albert Network Model

DOE Office of Scientific and Technical Information (OSTI.GOV)

Chassin, David P.; Posse, Christian

2005-09-15

The reliability of electric transmission systems is examined using a scale-free model of network topology and failure propagation. The topologies of the North American eastern and western electric grids are analyzed to estimate their reliability based on the Barabasi-Albert network model. A commonly used power system reliability index is computed using a simple failure propagation model. The results are compared to the values of power system reliability indices previously obtained using standard power engineering methods, and they suggest that scale-free network models are usable to estimate aggregate electric grid reliability.

Nanoparticles for bone tissue engineering.

Vieira, Sílvia; Vial, Stephanie; Reis, Rui L; Oliveira, J Miguel

2017-05-01

Tissue engineering (TE) envisions the creation of functional substitutes for damaged tissues through integrated solutions, where medical, biological, and engineering principles are combined. Bone regeneration is one of the areas in which designing a model that mimics all tissue properties is still a challenge. The hierarchical structure and high vascularization of bone hampers a TE approach, especially in large bone defects. Nanotechnology can open up a new era for TE, allowing the creation of nanostructures that are comparable in size to those appearing in natural bone. Therefore, nanoengineered systems are now able to more closely mimic the structures observed in naturally occurring systems, and it is also possible to combine several approaches - such as drug delivery and cell labeling - within a single system. This review aims to cover the most recent developments on the use of different nanoparticles for bone TE, with emphasis on their application for scaffolds improvement; drug and gene delivery carriers, and labeling techniques. © 2017 American Institute of Chemical Engineers Biotechnol.

2016-07-08

Process modeling can lead to of advantages such as helping in process control, reducing process costs and product quality improvement. This work proposes a solid-state fermentation distributed parameter model composed by seven differential equations with seventeen parameters to represent the process. Also, parameters estimation with a parameters identifyability analysis (PIA) is performed to build an accurate model with optimum parameters. Statistical tests were made to verify the model accuracy with the estimated parameters considering different assumptions. The results have shown that the model assuming substrate inhibition better represents the process. It was also shown that eight from the seventeen original model parameters were nonidentifiable and better results were obtained with the removal of these parameters from the estimation procedure. Therefore, PIA can be useful to estimation procedure, since it may reduce the number of parameters that can be evaluated. Further, PIA improved the model results, showing to be an important procedure to be taken. © 2016 American Institute of Chemical Engineers Biotechnol.

Motivations, interests and retention of female minority engineering students

NASA Astrophysics Data System (ADS)

Syed, Naila

In an effort to potentially increase low enrollment of females, particularly minorities, in Engineering programs, this study used a survey to determine motivations, interests and retention of current female Engineering students. A total of 82 participants from varied ethnic (non-Hispanic white, Euro-American, African American, Hispanic American, Asian American, South Asian, Arab American, and Native American participants) and education (high school senior, undergraduate, graduate, and in-service Engineers) backgrounds filled out the survey. With approximately half of the participants being non-minorities (non-Hispanic white or Euro-American), they served as the `control' group for the data, and the comparison group was the minority participants. Notable differences between the two groups were: student participation in female community groups, and extra-curricular activities like sports and arts (writing, drama and band) clubs. Increasing female-minority participation in these clubs and other extra-curricular activities may potentially increase their enrollment numbers in Engineering programs.

Application of iterative robust model-based optimal experimental design for the calibration of biocatalytic models.

2017-09-01

The aim of model calibration is to estimate unique parameter values from available experimental data, here applied to a biocatalytic process. The traditional approach of first gathering data followed by performing a model calibration is inefficient, since the information gathered during experimentation is not actively used to optimize the experimental design. By applying an iterative robust model-based optimal experimental design, the limited amount of data collected is used to design additional informative experiments. The algorithm is used here to calibrate the initial reaction rate of an ω-transaminase catalyzed reaction in a more accurate way. The parameter confidence region estimated from the Fisher Information Matrix is compared with the likelihood confidence region, which is not only more accurate but also a computationally more expensive method. As a result, an important deviation between both approaches is found, confirming that linearization methods should be applied with care for nonlinear models. © 2017 American Institute of Chemical Engineers Biotechnol.

2000-11-01

The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government, and military. Projections are that, in the 21st century, there will be even greater needs for more scientists, engineers, information technologists, and other types of scientific workers. The data from this study indicate that more inclusive history of science and technology can be used as a means for encouraging more people from under-represented groups to become scientifically literate and to pursue science and engineering careers.

Material experiments: Environment and engineering institutions in the early American republic.

In nineteenth-century America, strength of materials, an engineering science, focused on empirical research that yielded practical tools about how to predict the behavior of a wide variety of materials engineers might encounter as they built the nation's infrastructure. This orientation toward "cookbook formulae" that could accommodate many different kinds of timber, stone, mortar, metals, and so on was specifically tailored for the American context, where engineers were peripatetic, materials diverse, and labor in short supply. But these methods also reflected deeper beliefs about the specialness of the landscape and the providential site of the American political experiment. As such, engineers' appreciation of natural bounty both emerged from and contributed to larger values about exceptionalism and the practical character of Americans.

2014-10-01

Models are used to represent aspects of the real world for specific purposes, and mathematical models have opened up new approaches in studying the behavior and complexity of biological systems. However, modeling is often time-consuming and requires significant computational resources for data development, data analysis, and simulation. Computational modeling has been successfully applied as an aid for metabolic engineering in microorganisms. But such model-based approaches have only recently been extended to plant metabolic engineering, mainly due to greater pathway complexity in plants and their highly compartmentalized cellular structure. Recent progress in plant systems biology and bioinformatics has begun to disentangle this complexity and facilitate the creation of efficient plant metabolic models. This review highlights several aspects of plant metabolic modeling in the context of understanding, predicting and modifying complex plant metabolism. We discuss opportunities for engineering photosynthetic carbon metabolism, sucrose synthesis, and the tricarboxylic acid cycle in leaves and oil synthesis in seeds and the application of metabolic modeling to the study of plant acclimation to the environment. The aim of the review is to offer a current perspective for plant biologists without requiring specialized knowledge of bioinformatics or systems biology. © 2014 American Society of Plant Biologists.

In this study, step variations in temperature, pH, and carbon substrate feeding rate were performed within five high cell density Escherichia coli fermentations to assess whether intraexperiment step changes, can principally be used to exploit the process operation space in a design of experiment manner. A dynamic process modeling approach was adopted to determine parameter interactions. A bioreactor model was integrated with an artificial neural network that describes biomass and product formation rates as function of varied fed-batch fermentation conditions for heterologous protein production. A model reliability measure was introduced to assess in which process region the model can be expected to predict process states accurately. It was found that the model could accurately predict process states of multiple fermentations performed at fixed conditions within the determined validity domain. The results suggest that intraexperimental variations of process conditions could be used to reduce the number of experiments by a factor, which in limit would be equivalent to the number of intraexperimental variations per experiment. © 2016 American Institute of Chemical Engineers Biotechnol.

In this study, shear-induced flocculation modeling of Chlorella sp. microalgae was conducted by combination of population balance modeling and CFD. The inhomogeneous Multiple Size Group (MUSIG) and the Euler-Euler two fluid models were coupled via Ansys-CFX-15 software package to achieve both fluid and particle dynamics during the flocculation. For the first time, a detailed model was proposed to calculate the collision frequency and breakage rate during the microalgae flocculation by means of the response surface methodology as a tool for optimization. The particle size distribution resulted from the model was in good agreement with that of the jar test experiment. Furthermore, the subsequent sedimentation step was also examined by removing the shear rate in both simulations and experiments. Consequently, variation in the shear rate and its effects on the flocculation behavior, sedimentation rate and recovery efficiency were evaluated. Results indicate that flocculation of Chlorella sp. microalgae under shear rates of 37, 182, and 387 s -1 is a promising method of pre-concentration which guarantees the cost efficiency of the subsequent harvesting process by recovering more than 90% of the biomass. © 2017 American Institute of Chemical Engineers Biotechnol.

Condensation of binary mixtures on horizontal tubes

NASA Astrophysics Data System (ADS)

Büchner, A.; Reif, A.; Rehfeldt, S.; Klein, H.

2017-12-01

The two most common models to describe the condensation of binary mixtures are the equilibrium model by Silver (Trans Inst Chem Eng 25:30-42, 1947) and the film model by Colburn and Drew (Transactions of the American Institute of Chemical Engineers 33:197-215, 1937), which is stated by Webb et al. (Int J Heat Mass Transf 39:3147-3156, 1996) as more accurate. The film model describes the outer heat transfer coefficient by subdividing it into two separate resistances against the heat transfer. The resistance of the liquid condensate film on the tube can be calculated with equations for the condensation of pure substances for the analogous flow pattern and geometry using the property data of the mixture. The resistance in the gas phase can be described by a thermodynamic parameter Z and the single phase heat transfer coefficient α G . In this work measurements for condensation of the binary mixtures n-pentane/iso-octane and iso-propanol/water on horizontal tubes for free convection are carried out. The obtained results are compared with the film model by Colburn and Drew (Transactions of the American Institute of Chemical Engineers 33:197-215, 1937). The comparison shows a rather big deviation between the theoretical model and the experimental results. To improve the prediction quality an own model based on dimensionless numbers is proposed, which describes the experimental results of this work significantly better than the film model.

An in-depth investigation of how various illumination conditions influence microalgal growth in photobioreactors (PBR) has been presented. Effects of both the light emission spectrum (white and red) and the light incident angle (0° and 60°) on the PBR surface were investigated. The experiments were conducted in two fully controlled lab-scale PBRs, a torus PBR and a thin flat-panel PBR for high cell density culture. The results obtained in the torus PBR were used to build the kinetic growth model of Chlorella vulgaris taken as a model species. The PBR model was then applied to the thin flat-panel PBR, which was run with various illumination conditions. Its detailed representation of local rate of photon absorption under various conditions (spectral calculation of light attenuation, incident angle influence) enabled the model to take into account all the tested conditions with no further adjustment. This allowed a detailed investigation of the coupling between radiation field and photosynthetic growth. Effects of all the radiation conditions together with pigment acclimation, which was found to be relevant, were investigated in depth. © 2016 American Institute of Chemical Engineers Biotechnol.

Mechanistic modeling of the loss of protein sieving due to internal and external fouling of microfilters.

PubMed

Bolton, Glen R; Apostolidis, Alex J

2017-09-01

Fed-batch and perfusion cell culture processes used to produce therapeutic proteins can use microfilters for product harvest. In this study, new explicit mathematical models of sieving loss due to internal membrane fouling, external membrane fouling, or a combination of the two were generated. The models accounted for membrane and cake structures and hindered solute transport. Internal membrane fouling was assumed to occur due to the accumulation of foulant on either membrane pore walls (pore-retention model) or membrane fibers (fiber-retention model). External cake fouling was assumed to occur either by the growth of a single incompressible cake layer (cake-growth) or by the accumulation of a number of independent cake layers (cake-series). The pore-retention model was combined with either the cake-series or cake-growth models to obtain models that describe internal and external fouling occurring either simultaneously or sequentially. The models were tested using well-documented sieving decline data available in the literature. The sequential pore-retention followed by cake-growth model provided a good fit of sieving decline data during beer microfiltration. The cake-series and cake-growth models provided good fits of sieving decline data during the microfiltration of a perfusion cell culture. The new models provide insights into the mechanisms of fouling that result in the loss of product sieving. © 2017 American Institute of Chemical Engineers Biotechnol.

Predicting performance in a first engineering calculus course: implications for interventions

NASA Astrophysics Data System (ADS)

Hieb, Jeffrey L.; Lyle, Keith B.; Ralston, Patricia A. S.; Chariker, Julia

2015-01-01

At the University of Louisville, a large, urban institution in the south-east United States, undergraduate engineering students take their mathematics courses from the school of engineering. In the fall of their freshman year, engineering students take Engineering Analysis I, a calculus-based engineering analysis course. After the first two weeks of the semester, many students end up leaving Engineering Analysis I and moving to a mathematics intervention course. In an effort to retain more students in Engineering Analysis I, the department collaborated with university academic support services to create a summer intervention programme. Students were targeted for the summer programme based on their score on an algebra readiness exam (ARE). In a previous study, the ARE scores were found to be a significant predictor of retention and performance in Engineering Analysis I. This study continues that work, analysing data from students who entered the engineering school in the fall of 2012. The predictive validity of the ARE was verified, and a hierarchical linear regression model was created using math American College Testing (ACT) scores, ARE scores, summer intervention participation, and several metacognitive and motivational factors as measured by subscales of the Motivated Strategies for Learning Questionnaire. In the regression model, ARE score explained an additional 5.1% of the variation in exam performance in Engineering Analysis I beyond math ACT score. Students took the ARE before and after the summer interventions and scores were significantly higher following the intervention. However, intervention participants nonetheless had lower exam scores in Engineering Analysis I. The following factors related to motivation and learning strategies were found to significantly predict exam scores in Engineering Analysis I: time and study environment management, internal goal orientation, and test anxiety. The adjusted R2 for the full model was 0.42, meaning that the model could explain 42% of the variation in Engineering Analysis I exam scores.

The influence of college choice on the success, ethnic identity, and professional sense of belonging of African American engineers

NASA Astrophysics Data System (ADS)

DeRamus-Suazo, Nicole L.

The purpose of this study was to reveal the perceptions of African American engineers on how college choice influenced their success, ethnic identity, and professional sense of belonging by documenting the unique experiences and success stories of African American engineers who attended four-year institutions, historically Black colleges and universities (HBCUs) and predominantly White institutions (PWIs). The research question was best answered through a qualitative, phenomenological study that depicted the lived experiences of individuals in their own voice. The governing interest was in discovering whether aspiring African American engineers, at this stage in their professional experience, favorably viewed their choice of HBCUs versus PWIs. Participants relayed how having a sense of belonging to their institution and having a supportive network of peers and faculty influenced and shaped their outlook on life. Several of the participants spoke of being resolute in achieving their goal to become an engineer despite the challenges faced in college and in the workforce. Whether participants attended an HBCU or PWI, they felt a sense of achievement and a competence to walk into any situation and succeed. Overwhelmingly, most participants expressed they would choose their undergraduate institution again if given the opportunity. African American engineers favorably viewed their undergraduate college choice as having given them an opportunity to achieve their professional aspirations.

Huebner, P.

2003-12-01

Bridging the geographic boundaries and providing educational opportunities is the goal of American Indian Programs at Arizona State University East. Since its inception in 1997, American Indian Programs has established programs and partnerships to provide opportunities and resources to Tribal communities throughout Arizona. From educational programs to enhance student achievement at the K-12 level to recruitment and retention of American Indian students at the post secondary level, American Indian Programs provides the resources to further the success of students in science, math, engineering and technology. Resource convergence is critical in providing opportunities to ensure the success of Indian students in science, math, engineering and technology. American Indian Programs has built successful programs based on partnerships between federal grant programs, corporate, federal and state agencies. Providing professional development for teachers, school assessment, science and math curriculum and data collection are the primary efforts at the K-12 level to increase student achievement. Enrichment programs to enhance K-12 activities include the development of the Arizona American Indian Science and Engineering Fair (the only State fair for American Indiana's in the country) supported entirely through corporate support, summer residential programs, after school activities and dual enrollment programs for high school students. ASU East's retention rate for first year students is 92 percent and 1in 6 graduating students enter graduate programs. American Indian Programs strives to build student relationships with federal, state and corporate agencies through internships and coops. This effort has led to the development of an E-mentoring program that allows students (and K-12 teachers) to work directly with practicing scientists, and engineers in research activities. New programs look to increase technology not only in Tribal schools but increase technology in the homes of students as well.

Race, class and gender in engineering education: A quantitative investigation of first year enrollment

NASA Astrophysics Data System (ADS)

Phillips, Canek Moises Luna

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate the relationship between the odds ratios of women and men enrolled in first year US engineering programs and institutional characteristics. To do this, I employ linear regression to study data from the American Society of Engineering Education (ASEE) and the National Center for Education Statistics (NCES) to quantify relationships between odds ratios and institutional characteristics. Results of the linear regression models showed significant relationships between the cost of universities and university selectivity and the odds ratios of women choosing engineering. I theorize how the results could be related to the operation of occupational segregation in engineering, particularly how class-based markers have been historically used by women to overcome gender-based segregation in engineering. In the second study, I examine longitudinal patterns of race, gender, and intersectional combinations of race and gender in enrollments of students in first year engineering programs across the United States (US). Using enrollment data from the American Society of Engineering Education and California Post-Secondary Education Commission, I construct measures of segregation to study how trends in the disparity of students by race could be related to increases in public school segregation nationally over the past 25 years. I found that as public school segregation levels increased nationally, underrepresentation of Black and Hispanics and overrepresentation of White and Asian students has moved further toward the extremes in first year engineering programs compared to these groups’ shares of high school enrollment. I conclude that the study of public school segregation and its effect on racial disparity needs greater attention, as well as that the investigation I conducted serves as a beginning towards pushing back on deficit model explanations of race and gender disparity in engineering. In the third study, I return to the investigation of odds ratios and institutional characteristics, constructing odds ratios using ASEE and NCES data based on the odds of enrollment in first year engineering programs between Asian, Black, and Hispanic students compared to White students. I again quantify the relationships between odds ratios and institutional characteristics using linear regression models and discuss results using theory based in the perspective of occupational segregation. In this case, results were inconclusive leading me to conclude that other variables that I did not consider, such as the segregation levels of schools that students come from before enrollment, should be considered as I develop my own future study into the topic.

This paper presents nearly three and a half centuries of American invention, and is particularly concerned with primary invention as distinct from development, production, and service engineering. One apparent but not real exception to this statement is that one section will be devoted to the American invention of production engineering. Various factors have stimulated, guided, and inhibited American inventiveness; indeed, colonial status during nearly half the historical period being examined all but stifled technological innovation. It will also become clear that American disenchantment with basic scientific activity diminished the relative magnitude of her innovations after the advent of the technique of applied research in Europe following the middle of the nineteenth century. This circumstance is particularly obvious in the cases of chemical and electrical engineering, the first of the applied sciences.

The purpose of this research study was to examine, for undergraduate women of various Asian American ethnic backgrounds, the influence of background contextual and college environment factors on their sense of academic self-efficacy and achievement in science, technology, engineering, and mathematics (STEM) majors. Social cognitive career theory and its critiques provided a theoretical foundation for relationships from past performance, socioeconomic status, acculturation, and college environment variables (compositional diversity, racial climate, gendered climate, academic peer support), to academic self-efficacy and achievement. Data were collected through an online survey. Instrumentation included the scales of Language, Identity, and Behavioral Acculturation; Gender Discrimination; Faculty and Classroom Behavior; Interactions with Peers; and Academic Milestones Self-efficacy. The participants were 228 Asian American undergraduate women in STEM at a large public, doctoral research extensive university on the east coast; the response rate was 51%. In three MANOVAs for nine social cognitive career variables, four ethnic groups (East, South, Southeast, and Multi-ethnic Asian American) significantly differed only on socioeconomic status. In path analysis, the initial model was not a good fit and was rejected. The model was respecified through statistical and theoretical evaluation, tested in exploratory analysis, and considered a good fit. The respecified model explained 36% of semester GPA (achievement) and 28% of academic self-efficacy. The academic achievement of Asian American women in STEM was related to past performance, background contextual factors, academic self-efficacy, academic peer support, and gendered climate. The strongest direct influence on achievement was academic self-efficacy followed by past performance. The total effect of Asian acculturation on achievement was negative and the total effect of American acculturation on achievement was not significant; academic self-efficacy mediated these complex relationships. The total effects of racial and gendered compositional diversity and racial climate on both academic self-efficacy and achievement were not significant. Students in majors with more female peers reported less academic peer support. In this study, when culturally specific variables embellished social cognitive career theory, the theory exhibited cultural validity for undergraduate Asian American women in STEM. The nature of the relationships among culturally specific variables and college environment variables, however, requires further study.

Charting the pipeline: Identifying the critical elements in the development of successful African American scientists, engineers, and mathematicians

NASA Astrophysics Data System (ADS)

Williams, Brian Anthony

Many educational researchers are concerned with the apparent poor performance of different racial and ethnic groups in the fields of science, engineering, and mathematics in the United States. Despite improvements in the performance of African Americans, Hispanic Americans, and Native Americans in these areas over the past decade, these groups are still less likely to enroll in advanced math and science courses or score at or above the proficient level in mathematics. Furthermore, these groups continue to be underrepresented in the nation's technical and scientific workforce. The purpose of this study was to identify the critical elements related to the success of African Americans in science, engineering, and mathematics. Specifically, this study was designed to answer the following questions as they pertained to African American graduate students: What factors were perceived to have contributed to the students' initial interest in science, engineering, or mathematics? What factors were perceived to have contributed to the students' decisions to continue their studies in their specific areas of interest? What factors, associated with the K--12 schooling experience, were perceived to have contributed to the students' success in science, engineering, or mathematics? The data for the study were acquired from interviews with 32 African American students (16 males and 16 females) who were engaged in graduate work in science, engineering, or mathematics. Four major themes emerged from the analysis of the interview data. The first was that all students were involved in experiences that allowed a significant level of participation in science, engineering, and mathematics. Second, all of the students experienced some form of positive personal intervention by another person. Third, all students possessed perceptions of these fields that involved some sort of positive outcome. Finally, all of the of the students believed they possessed intrinsic qualities that qualified and prepared them for their involvement with science, engineering, and mathematics. These four themes exhibited themselves in different ways during the course of the students' lives. As a result, the discussion of the results of the study was divided among the three developmental periods: the interest-building phase, the knowledge-acquisition phase, and the careerbuilding phase. The study's findings provide valuable information to schools, educators, policy makers, and researchers on how to prepare effectively all children for a science and technology driven society, and for some, induction into tomorrow's scientific community.

Modeling Sources of Teaching Self-Efficacy for Science, Technology, Engineering, and Mathematics Graduate Teaching Assistants.

PubMed

DeChenne, Sue Ellen; Koziol, Natalie; Needham, Mark; Enochs, Larry

2015-01-01

Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor's belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs from nine different STEM departments at a midsized research university. Structural equation modeling reveals that K-12 teaching experience, hours and perceived quality of GTA PD, and perception of the departmental facilitating environment are significant factors that explain 32% of the variance in the teaching self-efficacy of STEM GTAs. This model highlights the important contributions of the departmental environment and GTA PD in the development of teaching self-efficacy for STEM GTAs. © 2015 S. E. DeChenne et al.

Women Break an Engineering Barrier: While Other Engineering Disciplines Stumble, BME Represents a Success Story in Attracting American Women to a Male-Dominated Field.

PubMed

Gutierrez, Claudia; Paulosky, Meaghan; Aguinaldo, Angeline; Gerhart, Jackie

2017-01-01

While the field of engineering as a whole is largely male-dominated, biomedical engineering (BME) is one area poised to overturn this trend. Women in the United States were awarded only 20% of all engineering B.S. degrees in 2015; in BME, however, 40.9% of the degree recipients were women. This stands in stark contrast to the more traditional fields of mechanical and electrical engineering, where women were awarded just 13.2% and 12.5% of B.S. degrees, respectively. This trend toward more female participation in BME continues at both the M.S. and Ph.D. degree levels. In fact, in 2015, BME had the highest percentage of female engineering M.S. degree recipients in the United States of all engineering disciplines, according to the American Society for Engineering Education (Figure 1).

A system identification approach for developing model predictive controllers of antibody quality attributes in cell culture processes.

Downey, Brandon; Schmitt, John; Beller, Justin; Russell, Brian; Quach, Anthony; Hermann, Elizabeth; Lyon, David; Breit, Jeffrey

2017-11-01

As the biopharmaceutical industry evolves to include more diverse protein formats and processes, more robust control of Critical Quality Attributes (CQAs) is needed to maintain processing flexibility without compromising quality. Active control of CQAs has been demonstrated using model predictive control techniques, which allow development of processes which are robust against disturbances associated with raw material variability and other potentially flexible operating conditions. Wide adoption of model predictive control in biopharmaceutical cell culture processes has been hampered, however, in part due to the large amount of data and expertise required to make a predictive model of controlled CQAs, a requirement for model predictive control. Here we developed a highly automated, perfusion apparatus to systematically and efficiently generate predictive models using application of system identification approaches. We successfully created a predictive model of %galactosylation using data obtained by manipulating galactose concentration in the perfusion apparatus in serialized step change experiments. We then demonstrated the use of the model in a model predictive controller in a simulated control scenario to successfully achieve a %galactosylation set point in a simulated fed-batch culture. The automated model identification approach demonstrated here can potentially be generalized to many CQAs, and could be a more efficient, faster, and highly automated alternative to batch experiments for developing predictive models in cell culture processes, and allow the wider adoption of model predictive control in biopharmaceutical processes. © 2017 The Authors Biotechnology Progress published by Wiley Periodicals, Inc. on behalf of American Institute of Chemical Engineers Biotechnol.

In the United States, most antibiotics are prescribed in ambulatory settings. Human factors engineering, which explores interactions between people and the place where they work, has successfully improved quality of care. However, human factors engineering models have not been explored to frame what is known about ambulatory antibiotic stewardship (AS) interventions and barriers and facilitators to their implementation. We conducted a systematic review and searched OVID MEDLINE, Embase, Scopus, Web of Science, and CINAHL to identify controlled interventions and qualitative studies of ambulatory AS and determine whether and how they incorporated principles from a human factors engineering model, the Systems Engineering Initiative for Patient Safety 2.0 model. This model describes how a work system (ambulatory clinic) contributes to a process (antibiotic prescribing) that leads to outcomes. The work system consists of 5 components, tools and technology, organization, person, tasks, and environment, within an external environment. Of 1,288 abstracts initially identified, 42 quantitative studies and 17 qualitative studies met inclusion criteria. Effective interventions focused on tools and technology (eg, clinical decision support and point-of-care testing), the person (eg, clinician education), organization (eg, audit and feedback and academic detailing), tasks (eg, delayed antibiotic prescribing), the environment (eg, commitment posters), and the external environment (media campaigns). Studies have not focused on clinic-wide approaches to AS. A human factors engineering approach suggests that investigating the role of the clinic's processes or physical layout or external pressures' role in antibiotic prescribing may be a promising way to improve ambulatory AS. © Copyright 2018 by the American Board of Family Medicine.

This study investigated the academic interests and goals of 223 African American, Latino/a, Southeast Asian, and Native American undergraduate students in two groups: biological science and engineering (S/E) majors. Using social cognitive career theory (Lent, Brown, & Hackett, 1994), we examined the relationships of social cognitive variables (math/science academic self-efficacy, math/science outcome expectations), along with the influence of ethnic variables (ethnic identity, other-group orientation) and perceptions of campus climate to their math/science interests and goal commitment to earn an S/E degree. Path analysis revealed that the hypothesized model provided good overall fit to the data, revealing significant relationships from outcome expectations to interests and to goals. Paths from academic self-efficacy to S/E goals and from interests to S/E goals varied for students in engineering and biological science. For both groups, other-group orientation was positively related to self-efficacy and support was found for an efficacy-mediated relationship between perceived campus climate and goals. Theoretical and practical implications of the study's findings are considered as well as future research directions.

Current industrial trends encourage the development of sustainable, environmentally friendly processes with minimal energy and material consumption. In particular, the increasing market demand in biopharmaceutical industry and the tight regulations in product quality necessitate efficient operating procedures that guarantee products of high purity. In this direction, process intensification via continuous operation paves the way for the development of novel, eco-friendly processes, characterized by higher productivity and lower production costs. This work focuses on the development of advanced control strategies for (i) a cell culture system in a bioreactor and (ii) a semicontinuous purification process. More specifically, we consider a fed-batch culture of GS-NS0 cells and the semicontinuous Multicolumn Countercurrent Solvent Gradient Purification (MCSGP) for the purification process. The controllers are designed following the PAROC framework/software platform and their capabilities are assessed in silico, against the process models. It is demonstrated that the proposed controllers efficiently manage to increase the system productivity, returning strategies that can lead to continuous, stable process operation. © 2017 American Institute of Chemical Engineers Biotechnol.

2017-03-01

In recent years, as a result of the process analytical technology initiative of the US Food and Drug Administration, many different works have been carried out on direct and in situ monitoring of critical parameters for mammalian cell cultures by Raman spectroscopy and multivariate regression techniques. However, despite interesting results, it cannot be said that the proposed monitoring strategies, which will reduce errors of the regression models and thus confidence limits of the predictions, are really optimized. Hence, the aim of this article is to optimize some critical steps of spectroscopic acquisition and data treatment in order to reach a higher level of accuracy and robustness of bioprocess monitoring. In this way, we propose first an original strategy to assess the most suited Raman acquisition time for the processes involved. In a second part, we demonstrate the importance of the interbatch variability on the accuracy of the predictive models with a particular focus on the optical probes adjustment. Finally, we propose a methodology for the optimization of the spectral variables selection in order to decrease prediction errors of multivariate regressions. © 2017 American Institute of Chemical Engineers Biotechnol.

A group of Mainland Chinese engineering students were asked to respond to 12 questions by indicating their design conventions and expectations about operations, directions-of-motion, and descriptions of movement for items such as doors, keys, taps, and knobs. Chi-square tests demonstrated strong response stereotypes for tasks of all 12 questions. A comparison of the stereotype strengths found here with that of Hong Kong Chinese and American engineering students reported earlier indicated that stereotype strengths of engineering students from the three regions were generally different. For some cases stereotype characteristics of two regions were more alike than the other, and also for some subjects in the three regions performed similarly. The Mainland and Hong Kong Chinese were more alike in making their choices on questions of conceptual compatibility, while more consistent preferences on movement compatibility and spatial compatibility were noted between the Mainland Chinese and American students than Hong Kong Chinese.

Russian Tu-144LL SST Roll-out for Joint NASA Research Program

NASA Technical Reports Server (NTRS)

1996-01-01

U.S. Ambassador Pickering addresses Russian and American dignitaries, industry representatives and members of the press during a roll-out ceremony for the modified Tu-144LL supersonic flying laboratory. The ceremony was held at the Zhukovsky Air Development Center near Moscow, Russia, on March 17, 1996. The 'LL' designation for the aircraft stands for Letayuschaya Laboratoriya, which means Flying Laboratory in Russian. NASA teamed with American and Russian aerospace industries for an extended period in a joint international research program featuring the Russian-built Tu-144LL supersonic aircraft. The object of the program was to develop technologies for a proposed future second-generation supersonic airliner to be developed in the 21st Century. The aircraft's initial flight phase began in June 1996 and concluded in February 1998 after 19 research flights. A shorter follow-on program involving seven flights began in September 1998 and concluded in April 1999. All flights were conducted in Russia from Tupolev's facility at the Zhukovsky Air Development Center near Moscow. The centerpiece of the research program was the Tu 144LL, a first-generation Russian supersonic jetliner that was modified by its developer/builder, Tupolev ANTK (aviatsionnyy nauchno-tekhnicheskiy kompleks-roughly, aviation technical complex), into a flying laboratory for supersonic research. Using the Tu-144LL to conduct flight research experiments, researchers compared full-scale supersonic aircraft flight data with results from models in wind tunnels, computer-aided techniques, and other flight tests. The experiments provided unique aerodynamic, structures, acoustics, and operating environment data on supersonic passenger aircraft. Data collected from the research program was being used to develop the technology base for a proposed future American-built supersonic jetliner. Although actual development of such an advanced supersonic transport (SST) is currently on hold, commercial aviation experts estimate that a market for up to 500 such aircraft could develop by the third decade of the 21st Century. The Tu-144LL used in the NASA-sponsored research program was a 'D' model with different engines than were used in production-model aircraft. Fifty experiments were proposed for the program and eight were selected, including six flight and two ground (engine) tests. The flight experiments included studies of the aircraft's exterior surface, internal structure, engine temperatures, boundary-layer airflow, the wing's ground-effect characteristics, interior and exterior noise, handling qualities in various flight profiles, and in-flight structural flexibility. The ground tests studied the effect of air inlet structures on airflow entering the engine and the effect on engine performance when supersonic shock waves rapidly change position in the engine air inlet. A second phase of testing further studied the original six in-flight experiments with additional instrumentation installed to assist in data acquisition and analysis. A new experiment aimed at measuring the in-flight deflections of the wing and fuselage was also conducted. American-supplied transducers and sensors were installed to measure nose boom pressures, angle of attack, and sideslip angles with increased accuracy. Two NASA pilots, Robert Rivers of Langley Research Center, Hampton, Virginia, and Gordon Fullerton from Dryden Flight Research Center, Edwards, California, assessed the aircraft's handling at subsonic and supersonic speeds during three flight tests in September 1998. The program concluded after four more data-collection flights in the spring of 1999. The Tu-144LL model had new Kuznetsov NK-321 turbofan engines rated at more than 55,000 pounds of thrust in full afterburner. The aircraft is 215 feet, 6 inches long and 42 feet, 2 inches high with a wingspan of 94 feet, 6 inches. The aircraft is constructed mostly of light aluminum alloy with titanium and stainless steel on the leading edges, elevons, rudder, and the under-surface of the rear fuselage.

Heinly, D.R.

Neither the National Society of Professional Engineers nor the American Consulting Engineers Council has lobbied to increase the solar tax credits. But, promoting solar is good business. The American Institute of Architects is not in favor of tax credits for active systems, correctly perceiving the architects' main chance for fees is in passive solar design. The engineering groups have not monitored solar legislation closely, but AIA has presented testimony in favor of subsidies for passive solar energy programs, which until recently had been left out. New money that is available for passive solar systems and the attitude toward solar aremore » discussed. (MCW)« less

Tissue engineering of the bladder--reality or myth? A systematic review.

Sloff, Marije; Simaioforidis, Vasileios; de Vries, Rob; Oosterwijk, Egbert; Feitz, Wout

2014-10-01

We systematically reviewed preclinical studies in the literature to evaluate the potential of tissue engineering of the bladder. Study outcomes were compared to the available clinical evidence to assess the feasibility of tissue engineering for future clinical use. Preclinical studies of tissue engineering for bladder augmentation were identified through a systematic search of PubMed and Embase™ from January 1, 1980 to January 1, 2014. Primary studies in English were included if bladder reconstruction after partial cystectomy was performed using a tissue engineered biomaterial in any animal species, with cystometric bladder capacity as an outcome measure. Outcomes were compared to clinical studies available at http://www.clinicaltrials.gov and published clinical studies. A total of 28 preclinical studies are included, demonstrating remarkable heterogeneity in study characteristics and design. Studies in which preoperative bladder volumes were compared to postoperative volumes were considered the most clinically relevant (18 studies). Bladder augmentation through tissue engineering resulted in a normal bladder volume in healthy animals, with the influence of a cellular component being negligible. Furthermore, experiments in large animal models (pigs and dogs) approximated the desired bladder volume more accurately than in smaller species. The initial clinical experience was based on seemingly predictive healthy animal models with a promising outcome. Unfortunately these results were not substantiated in all clinical trials, revealing dissimilar outcomes in different clinical/disease backgrounds. Thus, the translational predictability of a model using healthy animals might be questioned. Through this systematic approach we present an unbiased overview of all published preclinical studies investigating the effect of bladder tissue engineering on cystometric bladder capacity. Preclinical research in healthy animals appears to show the feasibility of bladder augmentation by tissue engineering. However, in view of the disappointing clinical results based on healthy animal models new approaches should also be evaluated in preclinical models using dysfunctional/diseased bladders. This endeavor may aid in the development of clinically applicable tissue engineered bladder augmentation with satisfactory long-term outcome.

Transforming attitudes and lives: Liberating African-American elementary and middle school students in out-of-school time STEM education

NASA Astrophysics Data System (ADS)

Smith, Charisse F.

Statistically, African-Americans, women, and the disabled are underrepresented in the fields of Science, Technology, Engineering, and Math (STEM). Historically, these underrepresented students, are described as being unrecognized and underdeveloped in the American STEM circuit. Many experience deficient and inadequate educational resources, are not encouraged to pursue STEM education and careers, and are confronted with copious obstructions. In this quantitative study, the researcher collected pretest and posttest survey data from a group of 4th, 5th, and 6th-grade African-American students in Title I funded schools. The reseacher used quantitative analysis to determine any significant differences in the science related attitudes between and within groups who participated in Out of School-Time Science, Technology, Engineering, and Mathematics programs and those who did not. Results revealed no significant differences in the science related attitudes between the groups of the students who participated in the Out of School Time-Science, Technology, Engineering, and Mathematics programs and those who did not. Results also revealed no significant differences in the science related attitudes within the groups of students who participated in the Out of School Time-Science, Technology, Engineering, and Mathematics programs and those who did not.

Minority Technical Organizations (MTO) are under-utilized as a valuable resource that can help develop the next generation of scientists and engineers. For over 90 years, the National Technical Association (NTA) (www.ntaonline.org) has been the premiere technical association for scientists, engineers, architects, technologist, educators, and technical business entrepreneurs for people of color, offering professional development, mentoring and awards recognition to technical professionals. NTA and its partners are developing a diverse workforce by emphasizing enhanced access opportunities to skills development for youth among underrepresented STEM populations. Established in 1925 by Charles Summer Duke, the first African American to receive an engineering degree from Harvard University, NTA served as the model organization for more than 40 other minority technical organizations that began forming in the 1970's. NTA has served as consultants to the US government on the status of African Americans in science and engineering. The first technical organization to establish community based technical mentoring programs targeting minorities, NTA shares information and assists institutions in identifying minority talent. Members developed the first science and engineering curriculum at Historically Black Colleges and Universities (HBCU's), and are working to produce more students with geoscience degrees to ensure greater career placement with increased minority participation in the geosciences. NTA addresses the lack of access, support, and the need for networking through the longest running annual conference for technical practitioners of color. A hallmark of NTA has been access and success through inter-organizational collaborations with communities of scholars, highly experienced professionals and students to discuss the definition of what is successful geoscience education, research, and employment.

Artificial neural network (ANN)-based prediction of depth filter loading capacity for filter sizing.

Agarwal, Harshit; Rathore, Anurag S; Hadpe, Sandeep Ramesh; Alva, Solomon J

2016-11-01

This article presents an application of artificial neural network (ANN) modelling towards prediction of depth filter loading capacity for clarification of a monoclonal antibody (mAb) product during commercial manufacturing. The effect of operating parameters on filter loading capacity was evaluated based on the analysis of change in the differential pressure (DP) as a function of time. The proposed ANN model uses inlet stream properties (feed turbidity, feed cell count, feed cell viability), flux, and time to predict the corresponding DP. The ANN contained a single output layer with ten neurons in hidden layer and employed a sigmoidal activation function. This network was trained with 174 training points, 37 validation points, and 37 test points. Further, a pressure cut-off of 1.1 bar was used for sizing the filter area required under each operating condition. The modelling results showed that there was excellent agreement between the predicted and experimental data with a regression coefficient (R 2 ) of 0.98. The developed ANN model was used for performing variable depth filter sizing for different clarification lots. Monte-Carlo simulation was performed to estimate the cost savings by using different filter areas for different clarification lots rather than using the same filter area. A 10% saving in cost of goods was obtained for this operation. © 2016 American Institute of Chemical Engineers Biotechnol. Prog., 32:1436-1443, 2016. © 2016 American Institute of Chemical Engineers.

A conceptual model for determining career choice of CHROME alumna based on farmer's conceptual models

Moore, Lisa Simmons

This qualitative program evaluation examines the career decision-making processes and career choices of nine, African American women who participated in the Cooperating Hampton Roads Organization for Minorities in Engineering (CHROME) and who graduated from urban, rural or suburban high schools in the year 2000. The CHROME program is a nonprofit, pre-college intervention program that encourages underrepresented minority and female students to enter science, technically related, engineering, and math (STEM) career fields. The study describes career choices and decisions made by each participant over a five-year period since high school graduation. Data was collected through an Annual Report, Post High School Questionnaires, Environmental Support Questionnaires, Career Choice Questionnaires, Senior Reports, and standardized open-ended interviews. Data was analyzed using a model based on Helen C. Farmer's Conceptual Models, John Ogbu's Caste Theory and Feminist Theory. The CHROME program, based on its stated goals and tenets, was also analyzed against study findings. Findings indicated that participants received very low levels of support from counselors and teachers to pursue STEM careers and high levels of support from parents and family, the CHROME program and financial backing. Findings of this study also indicated that the majority of CHROME alumna persisted in STEM careers. The most successful participants, in terms of undergraduate degree completion and occupational prestige, were the African American women who remained single, experienced no critical incidents, came from a middle class to upper middle class socioeconomic background, and did not have children.

Revisiting the case for genetically engineered mouse models in human myelodysplastic syndrome research.

PubMed

Zhou, Ting; Kinney, Marsha C; Scott, Linda M; Zinkel, Sandra S; Rebel, Vivienne I

2015-08-27

Much-needed attention has been given of late to diseases specifically associated with an expanding elderly population. Myelodysplastic syndrome (MDS), a hematopoietic stem cell-based blood disease, is one of these. The lack of clear understanding of the molecular mechanisms underlying the pathogenesis of this disease has hampered the development of efficacious therapies, especially in the presence of comorbidities. Mouse models could potentially provide new insights into this disease, although primary human MDS cells grow poorly in xenografted mice. This makes genetically engineered murine models a more attractive proposition, although this approach is not without complications. In particular, it is unclear if or how myelodysplasia (abnormal blood cell morphology), a key MDS feature in humans, presents in murine cells. Here, we evaluate the histopathologic features of wild-type mice and 23 mouse models with verified myelodysplasia. We find that certain features indicative of myelodysplasia in humans, such as Howell-Jolly bodies and low neutrophilic granularity, are commonplace in healthy mice, whereas other features are similarly abnormal in humans and mice. Quantitative hematopoietic parameters, such as blood cell counts, are required to distinguish between MDS and related diseases. We provide data that mouse models of MDS can be genetically engineered and faithfully recapitulate human disease. © 2015 by The American Society of Hematology.

A wind tunnel test program to determine aerodynamic interference heating on the North American Rockwell orbiter mated with the General Dynamics Convair booster is discussed. The tests were conducted at the Arnold Engineering Development Center (AEDC) in Tunnel B of the von Karman Gas Dynamics Facility (VKF). The test period was June 1971. Heat-transfer rates were determined by the phase-change paint technique on 0.013-scale Stycast models using Tempilaq as the surface temperature indicator. The nominal test conditions were: Mach 8, free-stream unit length Reynolds numbers of 1.25 x one million and 2.55 x one million angles of attack of -5, 0, +5 deg. Model details, test conditions, phase-change paint photographs and reduced heat-transfer coefficients are presented.

Research approach to teaching groundwater biodegradation in karst aquifers

USGS Publications Warehouse

2006-01-01

TSU in partnership with the USGS has conducted extensive research regarding biode??gradation of contaminants in karst aquifers. This research resulted in the development of a numerical approach to modeling biodegradation of contaminants in karst aquifers that is taught to environmental engineering students in several steps. First, environmental engineering students are taught chemical-reaction engineering principles relating to a wide variety of environmental fate and transport issues. Second, as part of TSU's engineering course curriculum, students use a non-ideal flow laboratory reactor system and run a tracer study to establish residence time distribution (RTD). Next, the students couple that formula to a first-order biodegradation rate and predict the removal of a biodegradable contaminant as a function of residence time. Following this, students are shown data collected from karst bedrock wells that suggest that karst aquifers are analogous to non-ideal flow reactors. The students are challenged to develop rates of biodegradation through lab studies and use their results to predict biodegradaton at an actual contaminated karst site. Field studies are also conducted to determine the accuracy of the students' predictions. This academic approach teaches biodegradation processes, rate-kinetic processes, hydraulic processes and numerical principles. The students are able to experience how chemical engineering principles can be applied to other situations, such as, modeling biodegradation of contaminants in karst aquifers. This paper provides background on the chemical engineering principles and karst issues used in the research-enhanced curriculum. ?? American Society for Engineering Education, 2006.

Preparing systems engineering and computing science students in disciplined methods, quantitative, and advanced statistical techniques to improve process performance

NASA Astrophysics Data System (ADS)

McCray, Wilmon Wil L., Jr.

The research was prompted by a need to conduct a study that assesses process improvement, quality management and analytical techniques taught to students in U.S. colleges and universities undergraduate and graduate systems engineering and the computing science discipline (e.g., software engineering, computer science, and information technology) degree programs during their academic training that can be applied to quantitatively manage processes for performance. Everyone involved in executing repeatable processes in the software and systems development lifecycle processes needs to become familiar with the concepts of quantitative management, statistical thinking, process improvement methods and how they relate to process-performance. Organizations are starting to embrace the de facto Software Engineering Institute (SEI) Capability Maturity Model Integration (CMMI RTM) Models as process improvement frameworks to improve business processes performance. High maturity process areas in the CMMI model imply the use of analytical, statistical, quantitative management techniques, and process performance modeling to identify and eliminate sources of variation, continually improve process-performance; reduce cost and predict future outcomes. The research study identifies and provides a detail discussion of the gap analysis findings of process improvement and quantitative analysis techniques taught in U.S. universities systems engineering and computing science degree programs, gaps that exist in the literature, and a comparison analysis which identifies the gaps that exist between the SEI's "healthy ingredients " of a process performance model and courses taught in U.S. universities degree program. The research also heightens awareness that academicians have conducted little research on applicable statistics and quantitative techniques that can be used to demonstrate high maturity as implied in the CMMI models. The research also includes a Monte Carlo simulation optimization model and dashboard that demonstrates the use of statistical methods, statistical process control, sensitivity analysis, quantitative and optimization techniques to establish a baseline and predict future customer satisfaction index scores (outcomes). The American Customer Satisfaction Index (ACSI) model and industry benchmarks were used as a framework for the simulation model.

The development of turbojet aircraft in Germany, Britain, and the United States: A multi-national comparison of aeronautical engineering, 1935--1946

NASA Astrophysics Data System (ADS)

Pavelec, Sterling Michael

In the 1930s aeronautical engineering needed revision. A presumptive anomaly was envisaged as piston-engine aircraft flew higher and faster. Radical alternatives to piston engines were considered in the unending quest for speed. Concurrently, but unwittingly, two turbojet engine programs were undertaken in Europe. The air-breathing three-stage turbojet engine was based on previous turbine technology; the revolutionary idea was the gas turbine as a prime mover for aircraft. In Germany, Dr. Hans von Ohain was the first to complete a flight-worthy turbojet engine for aircraft. Installed in a Heinkel designed aircraft, the Germans began the jet age on 27 August 1939. The Germans led throughout the war and were the first to produce jet aircraft for combat operations. The principal limiting factor for the German jet program was a lack of reliable engines. The continuing myths that Hitler orders, too little fuel, or too few pilots hindered the program are false. In England, Frank Whittle, without substantial support, but with dogged determination, also developed a turbojet engine. The British came second in the jet race when the Whittle engine powered the Gloster Pioneer on 15 May 1941. The Whittle-Gloster relationship continued and produced the only Allied combat jet aircraft during the war, the Meteor, which was confined to Home Defense in Britain. The American turbojet program was built directly from the Whittle engine. General Electric copied the Whittle designs and Bell Aircraft was contracted to build the first American jet plane. The Americans began the jet age on 1 October 1942 with a lackluster performance from their first jet, the Airacomet. But the Americans forged ahead, and had numerous engine and airframe programs in development by the end of the war. But, the Germans did it right and did it first. Partly because of a predisposition towards excellent engineering and physics, partly out of necessity, the Germans were able to produce combat turbojet aircraft during the war. The Allies lagged from a lack of necessity, operational incompatibility, and stringent acceptance requirements. By the end of the war the Germans needed qualitative technological superiority to combat an overwhelming Allied quantitative advantage.

Understanding him in STEM: Sharing the stories of African American male scholars in engineering academic programs at a predominantly White university

NASA Astrophysics Data System (ADS)

Hayes, Robert E., III

Globalization of the world economy has confirmed the need for citizens to exemplify competitive capacities in science, technology, engineering, and mathematics fields. Since the 1970s, American higher education has seen increasing numbers of students entering college but has witnessed a decline in the number of students enrolling in STEM programs. African American men fall behind other students in regards to academic performance, persistence, and success throughout primary, secondary, and tertiary schooling. Accordingly, participation of African American men in STEM disciplines is low in comparison to White males and other race groups. Various factors have been identified as contributing to the academic failures of Black men. Poor academic and social preparedness, racial identity issues, institutional climates, negative stereotypes, and fear of success have been cited as potential contributors to the relative invisibility of African American men in STEM disciplines. This study explores the life stories of five African American male scholars in the college of engineering at a predominantly white university. The goal of the qualitative investigation is to help university faculty and administrators understand the institutional, interpersonal, and collective mechanisms influencing the success identities of African American male undergraduates in STEM academic programs. Understanding the lived experiences of this population may help universities innovate stronger supports for men of color in college and broaden the borders for all students interested in STEM careers.

Vaccination is one of the most successful public health interventions being a cost-effective tool in preventing deaths among young children. The earliest vaccines were developed following empirical methods, creating vaccines by trial and error. New process development tools, for example mathematical modeling, as well as new regulatory initiatives requiring better understanding of both the product and the process are being applied to well-characterized biopharmaceuticals (for example recombinant proteins). The vaccine industry is still running behind in comparison to these industries. A production process for a new Haemophilus influenzae type b (Hib) conjugate vaccine, including related quality control (QC) tests, was developed and transferred to a number of emerging vaccine manufacturers. This contributed to a sustainable global supply of affordable Hib conjugate vaccines, as illustrated by the market launch of the first Hib vaccine based on this technology in 2007 and concomitant price reduction of Hib vaccines. This paper describes the development approach followed for this Hib conjugate vaccine as well as the mathematical modeling tool applied recently in order to indicate options for further improvements of the initial Hib process. The strategy followed during the process development of this Hib conjugate vaccine was a targeted and integrated approach based on prior knowledge and experience with similar products using multi-disciplinary expertise. Mathematical modeling was used to develop a predictive model for the initial Hib process (the 'baseline' model) as well as an 'optimized' model, by proposing a number of process changes which could lead to further reduction in price. © 2016 American Institute of Chemical Engineers Biotechnol.

Atherosclerosis can be achieved in animals by germline genetic engineering, leading to hypercholesterolemia, but such models are constrained to few species and strains, and they are difficult to combine with other powerful techniques involving genetic manipulation or variation. To develop a method for induction of atherosclerosis without germline genetic engineering. Recombinant adeno-associated viral vectors were engineered to encode gain-of-function proprotein convertase subtilisin/kexin type 9 mutants, and mice were given a single intravenous vector injection followed by high-fat diet feeding. Plasma proprotein convertase subtilisin/kexin type 9 and total cholesterol increased rapidly and were maintained at high levels, and after 12 weeks, mice had atherosclerotic lesions in the aorta. Histology of the aortic root showed progression of lesions to the fibroatheromatous stage. To demonstrate the applicability of this method for rapid analysis of the atherosclerosis susceptibility of a mouse strain and for providing temporal control over disease induction, we demonstrated the accelerated atherosclerosis of mature diabetic Akita mice. Furthermore, the versatility of this approach for creating atherosclerosis models also in nonmurine species was demonstrated by inducing hypercholesterolemia and early atherosclerosis in Golden Syrian hamsters. Single injections of proprotein convertase subtilisin/kexin type 9-encoding recombinant adeno-associated viral vectors are a rapid and versatile method to induce atherosclerosis in animals. This method should prove useful for experiments that are high-throughput or involve genetic techniques, strains, or species that do not combine well with current genetically engineered models. © 2014 American Heart Association, Inc.

Foreign science and engineering doctoral attainment at American universities

NASA Astrophysics Data System (ADS)

Hamilton, Robert V.

This dissertation analyzes the nearly 100,000 foreign students who attained science and engineering (S&E) doctorates in the five fields of physical sciences, life sciences, engineering, mathematics and computer sciences, and social and behavioral sciences at American universities from 1994 to 2005. Two models are presented. In the first model controlling for population, multivariate regression results testing for whether foreign students from higher or lower income nations (181 nations) tended to attain S&E doctorates showed that certain S&E fields tended to be represented by students from higher income nations early in the time period (e.g. 1994 to 1999) but the national income variable explaining foreign S&E doctoral attainment was not statistically significant in four of the fields after the year 2000. Four nations, China, India, South Korea and Taiwan stand out due to their large S&E doctoral student presence at American universities, but virtually all growth in foreign doctoral attainment in four of the S&E fields from 1994 to 2005 came from Chinese students, and this growth was most pronounced after the year 2001. In short, whereas the foreign student populations from South Korea and Taiwan were the outliers in 1994 and as such skewed testing results, they had largely been displaced in 2005 by the increased presence of Chinese students. From the US public policy perspective, to the extent that growth in foreign S&E doctoral attainment is an issue to include its related costs and benefits, the appropriate policy focus should shift more specifically towards the growth in Chinese S&E doctoral attainment. Further, with the exception of China and India, foreign doctoral students from the lowest income nations of the world in all five S&E fields were greatly under represented on American campuses from 1994 to 2005. Testing results from the second model complement the findings in the first model. Whereas the first model tested for the effects of national income on foreign S&E doctoral attainment, the second model tested for changes in foreign S&E doctoral attainment over the time period 1994 to 2005. Specifically, testing results for the second model indicated that changes in S&E doctoral attainment by students from the lower income nations tended to more closely track changes in education-related R&D funding compared to students from higher income nations. These results suggest that to the extent the US government desires to increase foreign doctoral attainment in specific S&E fields, students from lower income nations might have a greater tendency to "chase" education-related R&D dollars in the targeted S&E fields. Finally, testing results for both models indicate that there was variation between the five S&E fields, and that highly-skilled migration patterns in certain S&E fields changed relatively quickly during the time period 1994 to 2005. These results suggest that foreign S&E doctoral attainment should be disaggregated both temporally and by S&E population in order to adequately measure and understand this phenomenon.

The Soviet Union has maintained a substantial and successful electric propulsion research and development effort since the 1950s; however, American researchers are generally unfamiliar with the Soviet accomplishments. Sources of information about Soviet electric propulsion research are noted. The development of plasma engines, a subset of the electric propulsion effort, is reviewed using numerous Soviet sources. The operational principles and status of several engines of the closed electron drift and high-current types are discussed. With recognition of the limited knowledge of the current Soviet program, the Soviet and American programs are compared, revealing some differences in program formulation and emphasis.

Tissue engineering technology has provided many useful culture models. This article reviews the merits of this technology in a hepatocyte culture system and describes the applications of the sandwich-cultured hepatocyte model in drug discovery. In addition, we also review recent investigations of the utility of the 3-dimensional bioprinted human liver tissue model and spheroid model. Finally, we present the future direction and developmental challenges of a hepatocyte culture model for the successful establishment of a microphysiological system, represented as an organ-on-a-chip and even as a human-on-a-chip. A merit of advanced culture models is their potential use for detecting hepatotoxicity through repeated exposure to chemicals as they allow long-term culture while maintaining hepatocyte functionality. As a future direction, such advanced hepatocyte culture systems can be connected to other tissue models for evaluating tissue-to-tissue interaction beyond cell-to-cell interaction. This combination of culture models could represent parts of the human body in a microphysiological system. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

Encouraging the pursuit of advanced degrees in science and engineering: Top-down and bottom-up methodologies

NASA Technical Reports Server (NTRS)

Maddox, Anthony B.; Smith-Maddox, Renee P.; Penick, Benson E.

1989-01-01

The MassPEP/NASA Graduate Research Development Program (GRDP) whose objective is to encourage Black Americans, Mexican Americans, American Indians, Puerto Ricans, and Pacific Islanders to pursue graduate degrees in science and engineering is described. The GRDP employs a top-down or goal driven methodology through five modules which focus on research, graduate school climate, technical writing, standardized examinations, and electronic networking. These modules are designed to develop and reinforce some of the skills necessary to seriously consider the goal of completing a graduate education. The GRDP is a community-based program which seeks to recruit twenty participants from a pool of Boston-area undergraduates enrolled in engineering and science curriculums and recent graduates with engineering and science degrees. The program emphasizes that with sufficient information, its participants can overcome most of the barriers perceived as preventing them from obtaining graduate science and engineering degrees. Experience has shown that the top-down modules may be complemented by a more bottom-up or event-driven methodology. This approach considers events in the academic and professional experiences of participants in order to develop the personal and leadership skills necessary for graduate school and similar endeavors.

The roles of family, culture, and social cognitive variables in the career interests and goals of Asian American college students.

PubMed

Hui, Kayi; Lent, Robert W

2018-01-01

Although family and cultural factors have been assumed to play important roles in the career development of Asian Americans, theory-driven research on this topic remains limited. We examined culturally relevant factors that may contribute to Asian Americans' consideration of fields in which they are overrepresented (e.g., science, technology, engineering) and underrepresented (e.g., education, social science). Drawing from social cognitive career theory, a culture-specific, social cognitive model of career interests and choice was tested in Holland's (1997) Investigative (I) and Social (S) themes. A sample of 802 Asian American undergraduates completed measures of family support, self-efficacy, outcome expectations, interest, and career choice consideration in relation to both Holland themes. Two indicators of acculturation/enculturation (adherence to Asian values and generation status in the United States) were also obtained. The model accounted for a substantial amount of variance in Asian American college students' career consideration in both themes. Family support and acculturation played varying roles, depending on the Holland theme. For example, family support was linked to career choice consideration both directly (in the S theme) and indirectly, via other predictors (in both themes). Contrary to expectations, the acculturation variables did not moderate the relation of family support or interest to career consideration in either theme. We discuss the implications of these findings for efforts to understand and facilitate the career development of Asian American college students.

Promotive and Corrosive Factors in African American Students' Math Beliefs and Achievement.

Diemer, Matthew A; Marchand, Aixa D; McKellar, Sarah E; Malanchuk, Oksana

2016-06-01

Framed by expectancy-value theory (which posits that beliefs about and the subjective valuation of a domain predict achievement and decision-making in that domain), this study examined the relationships among teacher differential treatment and relevant math instruction on African American students' self-concept of math ability, math task value, and math achievement. These questions were examined by applying structural equation modeling to 618 African American youth (45.6 % female) followed from 7th to 11th grade in the Maryland Adolescent Development in Context Study. While controlling for gender and prior math achievement, relevant math instruction promoted and teacher differential treatment corroded students' math beliefs and achievement over time. Further, teacher discrimination undermined students' perceptions of their teachers, a mediating process under-examined in previous inquiry. These findings suggest policy and practice levers to narrow opportunity gaps, as well as foster math achievement and science, technology, engineering and math success.

In the spring of 2016 the City of Las Vegas and the Southern Illinois University began collaborating on a project that seeks to assess the city's current vulnerability to drought, extreme heat, and extreme precipitation patterns, as well as the response mechanisms that are already in place within its jurisdiction. The document analyzes a series of scenarios to assess to what extent the vulnerability of four Key Planning Areas will change in the long term (30-50 years), what will be the most affected city operations, and what mechanisms the City will need to put into place to adapt to such changes. As part of the vulnerability report, this study assessed the impacts of climate change in the existing stormwater system of the Gowan watershed within City of Las Vegas, NV, by assessing projected design storms. The climate change projection for the region was evaluated using the high-resolution North American Regional Climate Change Assessment Program (NARCCAP) climate model data. The design storms (6h 100y) were calculated using the best fitted probability distribution among twenty-seven distributions for the historic and future NARCCAP climate model projection. North American Regional Reanalysis (NARR) data were used to assess the performance of NARCCAP data. The projected design storms were implemented in an existing U.S. Army Corps of Engineers' Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS) model developed by Clark County Regional Flood Control District (CCRFCD), Las Vegas. The simulation results showed an increase in the design storms which exceeded the capacity of existing stormwater infrastructure.

CFD of mixing of multi-phase flow in a bioreactor using population balance model.

2016-05-01

Mixing in bioreactors is known to be crucial for achieving efficient mass and heat transfer, both of which thereby impact not only growth of cells but also product quality. In a typical bioreactor, the rate of transport of oxygen from air is the limiting factor. While higher impeller speeds can enhance mixing, they can also cause severe cell damage. Hence, it is crucial to understand the hydrodynamics in a bioreactor to achieve optimal performance. This article presents a novel approach involving use of computational fluid dynamics (CFD) to model the hydrodynamics of an aerated stirred bioreactor for production of a monoclonal antibody therapeutic via mammalian cell culture. This is achieved by estimating the volume averaged mass transfer coefficient (kL a) under varying conditions of the process parameters. The process parameters that have been examined include the impeller rotational speed and the flow rate of the incoming gas through the sparger inlet. To undermine the two-phase flow and turbulence, an Eulerian-Eulerian multiphase model and k-ε turbulence model have been used, respectively. These have further been coupled with population balance model to incorporate the various interphase interactions that lead to coalescence and breakage of bubbles. We have successfully demonstrated the utility of CFD as a tool to predict size distribution of bubbles as a function of process parameters and an efficient approach for obtaining optimized mixing conditions in the reactor. The proposed approach is significantly time and resource efficient when compared to the hit and trial, all experimental approach that is presently used. © 2016 American Institute of Chemical Engineers Biotechnol.

Evaluation of differences between dual salt-pH gradient elution and mono gradient elution using a thermodynamic model: Simultaneous separation of six monoclonal antibody charge and size variants on preparative-scale ion exchange chromatographic resin.

2018-02-21

The efficiencies of mono gradient elution and dual salt-pH gradient elution for separation of six mAb charge and size variants on a preparative-scale ion exchange chromatographic resin are compared in this study. Results showed that opposite dual salt-pH gradient elution with increasing pH gradient and simultaneously decreasing salt gradient is best suited for the separation of these mAb charge and size variants on Eshmuno ® CPX. Besides giving high binding capacity, this type of opposite dual salt-pH gradient also provides better resolved mAb variant peaks and lower conductivity in the elution pools compared to single pH or salt gradients. To have a mechanistic understanding of the differences in mAb variants retention behaviors of mono pH gradient, parallel dual salt-pH gradient, and opposite dual salt-pH gradient, a linear gradient elution model was used. After determining the model parameters using the linear gradient elution model, 2D plots were used to show the pH and salt dependencies of the reciprocals of distribution coefficient, equilibrium constant, and effective ionic capacity of the mAb variants in these gradient elution systems. Comparison of the 2D plots indicated that the advantage of opposite dual salt-pH gradient system with increasing pH gradient and simultaneously decreasing salt gradient is the noncontinuous increased acceleration of protein migration. Furthermore, the fitted model parameters can be used for the prediction and optimization of mAb variants separation in dual salt-pH gradient and step elution. © 2018 American Institute of Chemical Engineers Biotechnol.

The under-representation of Native Americans in engineering and science at the student and practicing engineer or scientist level is a national problem. To begin addressing this problem Washington State University (WSU) has initiated discussio with local Native American tribes to strengthen the relationship between WSU and the tribes and to improve the educational opportunities available to tribal members. The Center for Multiphase Environmental Research (CMER) received a 1999 National Science Foundation (NSF) Integrative Graduate Education and Research Training (IGERT) grant to train Ph.D. students. The main goal of the program is to foster multidisciplinary research and education for future scientists and engineers in the broad field of study that incorporates the fate and transport of environmentally significant species between interfaces. We are also focused on recruiting and educating Native American students. CMER is committed to cultivating its relationship with Native American tribes by identifying the environmental concerns of the tribes and developing collaborative research efforts utilizing CMER's infrastructure. Through these collaborative projects the CMER hopes to better understand the social and cultural aspects important to the tribes and develop the familiarity needed to effectively enhance student recruitment. This poster highlights the CMER's interdisciplinary research and teaching efforts and focuses on Native American recruitment.

"Sounds like something a white man should be doing": Academic identity in African American female engineering students

NASA Astrophysics Data System (ADS)

Stitt, Rashunda LaRuth

This study exposed the way African American female engineering students constructed their academic identities by focusing on their lived experiences. Participants included nine engineering students at Mid-South University (pseudonym) who identified as African American females. Participants were required to sit for one semi-structured academic life history interview that focused on their academic experiences from early childhood to present. This study employed two levels of theory in order to obtain a comprehensive view of participants' experiences. Black feminist theory, which accounts for the intersectionality of participants' race and gender, served as the macro level theory and academic identity, which accounts for the individual's sense of identity within an academic context, served as the mid-level theory. I engaged in thematic analysis, narrative analysis, and creative analytic practice in order to highlight similarities between participants' stories, differences between participants' experiences, and to make this research accessible to individuals outside of academia. As a result, the following three themes emerged to highlight the similarities between participants: (a) just because you struggle, does not mean you should quit; (b) engineering is something you cannot do alone; and (c) I can be creative and do math and science? That's cool! Narrative analysis exposed the academic identity statuses of participants to be either identity achieved, identity moratorium, identity foreclosed or identity diffused. The final piece of analysis involved creating a play that highlights the experiences of an African American girl's pursuit of her engineering degree. Additionally, the final chapter provides conclusions, implications, suggestions for future research, and limitations of the current study.

Biophysical wave stimulus has been used as an effective tool to promote cellular maturation and differentiation in the construction of engineered tissue. Pulsed electromagnetic fields (PEMFs) and sound waves have been selected as effective stimuli that can promote neural differentiation. The aim of this study was to investigate the synergistic effect of PEMFs and sound waves on the neural differentiation potential in vitro and in vivo using human bone marrow mesenchymal stem cells (hBM-MSCs). In vitro, neural-related genes in hBM-MSCs were accelerated by the combined exposure to both waves more than by individual exposure to PEMFs or sound waves. The combined wave also up-regulated the expression of neural and synaptic-related proteins in a three-dimensional (3-D) culture system through the phosphorylation of extracellular signal-related kinase. In a mouse model of photochemically induced ischemia, exposure to the combined wave reduced the infarction volume and improved post-injury behavioral activity. These results indicate that a combined stimulus of biophysical waves, PEMFs and sound can enhance and possibly affect the differentiation of MSCs into neural cells. Our study is meaningful for highlighting the potential of combined wave for neurogenic effects and providing new therapeutic approaches for neural cell therapy. © 2016 American Institute of Chemical Engineers Biotechnol.

An examination of the identity development of African American undergraduate engineering students attending an HBCU

NASA Astrophysics Data System (ADS)

Taylor, Kenneth J.

This study examined the identity development for a sample of 90 African American undergraduate engineering male and female students attending an HBCU. Using the Student Development Task and Lifestyle Assessment (SDTLA), which is based on Chickering and Reisser's identity development theory, differences in identity development were examined with respect to gender, academic classification, and grade point average. Previous research has shown the need to look beyond academic factors to understand and influence the persistence of African American engineering students. Non-cognitive factors, including identity development have proven to be influential in predicting persistence, especially for African American engineering students. Results from the analysis revealed significant means for academic classification and five of the dependent variables to include career planning peer relations, emotional autonomy, educational involvement, and establishing and clarifying purpose. Post hoc analysis confirmed significant differences for four of those dependent variables. However, the analysis failed to confirm statistical significant differences in peer relations due to academic classification. The significant decline in the mean scores for development in these four areas, as students progressed from sophomore to senior year revealed strong implications for the need to provide programming and guidance for those students. Institutions of higher education should provide more attention to the non-cognitive areas of development as a means of understanding identity development and working toward creating support systems for students.

Seeing through the lens of social justice: A threshold for engineering

NASA Astrophysics Data System (ADS)

Kabo, Jens David

In recent times the need for educational research dedicated to engineering education has been recognised. This PhD project is a contribution to the development of engineering education scholarship and the growing body of engineering education research. In this project it was recognised that problem solving is a central activity to engineering. However, it was also recognised that the conditions for doing engineering are changing, especially in light of pressing issues of poverty and environmental sustainability that humanity currently faces, and as a consequence, engineering education needs to emphasise problem definition to a greater extent. One mechanism for achieving this, which has been adopted by some engineering educators in recent years, is through courses that explicitly relate engineering to social justice. However, creating this relationship requires critical interdisciplinary thinking that is alien to most engineering students. In this dissertation it is suggested that for engineering students, and more generally, engineers, looking at their practice and profession through a social justice lens might be seen as a threshold that needs to be crossed. By studying the variation present among students in three different courses at three different North American universities, the intention was to understand how students approach and internalise social justice as a perspective on engineering and/or develop their abilities to think critically. A conceptual model to frame the study was developed by combining elements of threshold concept theory and the educational research methodology, phenomenographic variation theory. All three of the courses studied operated on a similar basic pedagogical model, however, the courses were framed differently, with social justice in the foreground or in the background with the focus on, in one case, ethics and in the other, sustainability. All courses studied appeared to be successful in encouraging engineering students to engage in critical thinking and a similar general trend in the development of students' conceptions of social justice was observed in each of the three courses. However, it does appear that if one is interested in developing an articulated understanding of social justice, with respect to engineering, that an explicit focus on social justice is preferable.

1985-01-01

The American Society of Civil Engineers views professional registration as an appropriate requirement for engineers, including those in government. The National Society of Professional Engineers makes registration a requirement for the grade of member and full privileges in the society. Some Federal agencies require engineering registration for certain positions in their agencies. Engineers in government service should consider the value of engineering registration to themselves and to their agencies and take pride in their professions and in their own capabilities by becoming registered engineers. They should also take steps to encourage their agencies to give more attention to engineering registration.

According to the latest report by the National Science Foundation, only eighty-three (83) African-Americans received doctoral degrees in all engineering disciplines in 2000. North Carolina A&T State University (NC A&T) awarded Ph.D.s to 15 African-Americans, in only two engineering disciplines over the past 4 years. It clearly indicates that the partnership between NASA and NC A&T plays a significant role in producing minority engineering Ph.D.s, which this country needs to establish an ethnically diverse workforce to compete in a global economy. Many of these students would not have been able to study for their doctoral degrees without the Ronald E. McNair Graduate Research Fellowship Program.

Success in Undergraduate Engineering Programs: A Comparative Analysis by Race and Gender

NASA Astrophysics Data System (ADS)

Lord, Susan

2010-03-01

Interest in increasing the number of engineering graduates in the United States and promoting gender equality and diversification of the profession has encouraged considerable research on women and minorities in engineering programs. Drawing on a framework of intersectionality theory, this work recognizes that women of different ethnic backgrounds warrant disaggregated analysis because they do not necessarily share a common experience in engineering education. Using a longitudinal, comprehensive data set of more than 79,000 students who matriculated in engineering at nine universities in the Southeastern United States, this research examines how the six-year graduation rates of engineering students vary by disaggregated combinations of gender and race/ethnicity. Contrary to the popular opinion that women drop out of engineering at higher rates, our results show that Asian, Black, Hispanic, Native American, and White women who matriculate in engineering are as likely as men to graduate in engineering in six years. In fact, Asian, Black, Hispanic, and Native American women engineering matriculants graduate at higher rates than men and there is a small difference for white students. 54 percent of White women engineering matriculants graduate in six-years compared with 53 percent of white men. For male and female engineering matriculants of all races, the most likely destination six years after entering college is graduation within engineering. This work underscores the importance of research disaggregated by race and gender and points to the critical need for more recruitment of women into engineering as the low representation of women in engineering education is primarily a reflection of their low representation at matriculation.

Robbins, Mary Clare; Usevitch, Bryan; Starks, Scott A.

1997-01-01

In 1995, The University of Texas at El Paso (UTEP) responded to the suggestion of NASA Jet Propulsion Laboratory (NASA JPL) to form a consortium comprised of California State University at Los Angeles (CSULA), North Carolina Agricultural and Technical University (NCAT), and UTEP from which developed the Minority Universities Systems Engineering (MUSE) Program. The mission of this consortium is to develop a unique position for minority universities in providing the nation's future system architects and engineers as well as enhance JPL's system design capability. The goals of this collaboration include the development of a system engineering curriculum which includes hands-on project engineering and design experiences. UTEP is in a unique position to take full advantage of this program since UTEP has been named a Model Institution for Excellence (MIE) by the National Science Foundation. The purpose of MIE is to produce leaders in Science, Math, and Engineering. Furthermore, UTEP has also been selected as the site for two new centers including the Pan American Center for Earth and Environmental Sciences (PACES) directed by Dr. Scott Starks and the FAST Center for Structural Integrity of Aerospace Systems directed by Dr. Roberto Osegueda. The UTEP MUSE Program operates under the auspices of the PACES Center.

An object-oriented, technology-adaptive information model

NASA Technical Reports Server (NTRS)

Anyiwo, Joshua C.

1995-01-01

The primary objective was to develop a computer information system for effectively presenting NASA's technologies to American industries, for appropriate commercialization. To this end a comprehensive information management model, applicable to a wide variety of situations, and immune to computer software/hardware technological gyrations, was developed. The model consists of four main elements: a DATA_STORE, a data PRODUCER/UPDATER_CLIENT and a data PRESENTATION_CLIENT, anchored to a central object-oriented SERVER engine. This server engine facilitates exchanges among the other model elements and safeguards the integrity of the DATA_STORE element. It is designed to support new technologies, as they become available, such as Object Linking and Embedding (OLE), on-demand audio-video data streaming with compression (such as is required for video conferencing), Worldwide Web (WWW) and other information services and browsing, fax-back data requests, presentation of information on CD-ROM, and regular in-house database management, regardless of the data model in place. The four components of this information model interact through a system of intelligent message agents which are customized to specific information exchange needs. This model is at the leading edge of modern information management models. It is independent of technological changes and can be implemented in a variety of ways to meet the specific needs of any communications situation. This summer a partial implementation of the model has been achieved. The structure of the DATA_STORE has been fully specified and successfully tested using Microsoft's FoxPro 2.6 database management system. Data PRODUCER/UPDATER and PRESENTATION architectures have been developed and also successfully implemented in FoxPro; and work has started on a full implementation of the SERVER engine. The model has also been successfully applied to a CD-ROM presentation of NASA's technologies in support of Langley Research Center's TAG efforts.

Modeling spatial distribution of oxygen in 3d culture of islet beta-cells.

Three-dimensional (3D) scaffold culture of pancreatic β-cell has been proven to be able to better mimic physiological conditions in the body. However, one critical issue with culturing pancreatic β-cells is that β-cells consume large amounts of oxygen, and hence insufficient oxygen supply in the culture leads to loss of β-cell mass and functions. This becomes more significant when cells are cultured in a 3D scaffold. In this study, in order to understand the effect of oxygen tension inside a cell-laden collagen culture on β-cell proliferation, a culture model with encapsulation of an oxygen-generator was established. The oxygen-generator was made by embedding hydrogen peroxide into nontoxic polydimethylsiloxane to avoid the toxicity of a chemical reaction in the β-cell culture. To examine the effectiveness of the oxygenation enabled 3D culture, the spatial-temporal distribution of oxygen tension inside a scaffold was evaluated by a mathematical modeling approach. Our simulation results indicated that an oxygenation-aided 3D culture would augment the oxygen supply required for the β-cells. Furthermore, we identified that cell seeding density and the capacity of the oxygenator are two critical parameters in the optimization of the culture. Notably, cell-laden scaffold cultures with an in situ oxygen supply significantly improved the β-cells' biological function. These β-cells possess high insulin secretion capacity. The results obtained in this work would provide valuable information for optimizing and encouraging functional β-cell cultures. © 2016 American Institute of Chemical Engineers Biotechnol.

Research Pilot C. Gordon Fullerton in Cockpit of TU-144LL SST Flying Laboratory

NASA Technical Reports Server (NTRS)

1998-01-01

NASA Research pilot C. Gordon Fullerton sits in cockpit of TU-144LL SST Flying Laboratory. Fullerton was one of two NASA pilots who flew the aircraft as part of a joint high speed research program. NASA teamed with American and Russian aerospace industries for an extended period in a joint international research program featuring the Russian-built Tu-144LL supersonic aircraft. The object of the program was to develop technologies for a proposed future second-generation supersonic airliner to be developed in the 21st Century. The aircraft's initial flight phase began in June 1996 and concluded in February 1998 after 19 research flights. A shorter follow-on program involving seven flights began in September 1998 and concluded in April 1999. All flights were conducted in Russia from Tupolev's facility at the Zhukovsky Air Development Center near Moscow. The centerpiece of the research program was the Tu 144LL, a first-generation Russian supersonic jetliner that was modified by its developer/builder, Tupolev ANTK (aviatsionnyy nauchno-tekhnicheskiy kompleks-roughly, aviation technical complex), into a flying laboratory for supersonic research. Using the Tu-144LL to conduct flight research experiments, researchers compared full-scale supersonic aircraft flight data with results from models in wind tunnels, computer-aided techniques, and other flight tests. The experiments provided unique aerodynamic, structures, acoustics, and operating environment data on supersonic passenger aircraft. Data collected from the research program was being used to develop the technology base for a proposed future American-built supersonic jetliner. Although actual development of such an advanced supersonic transport (SST) is currently on hold, commercial aviation experts estimate that a market for up to 500 such aircraft could develop by the third decade of the 21st Century. The Tu-144LL used in the NASA-sponsored research program was a 'D' model with different engines than were used in production-model aircraft. Fifty experiments were proposed for the program and eight were selected, including six flight and two ground (engine) tests. The flight experiments included studies of the aircraft's exterior surface, internal structure, engine temperatures, boundary-layer airflow, the wing's ground-effect characteristics, interior and exterior noise, handling qualities in various flight profiles, and in-flight structural flexibility. The ground tests studied the effect of air inlet structures on airflow entering the engine and the effect on engine performance when supersonic shock waves rapidly change position in the engine air inlet. A second phase of testing further studied the original six in-flight experiments with additional instrumentation installed to assist in data acquisition and analysis. A new experiment aimed at measuring the in-flight deflections of the wing and fuselage was also conducted. American-supplied transducers and sensors were installed to measure nose boom pressures, angle of attack, and sideslip angles with increased accuracy. Two NASA pilots, Robert Rivers of Langley Research Center, Hampton, Virginia, and Gordon Fullerton from Dryden Flight Research Center, Edwards, California, assessed the aircraft's handling at subsonic and supersonic speeds during three flight tests in September 1998. The program concluded after four more data-collection flights in the spring of 1999. The Tu-144LL model had new Kuznetsov NK-321 turbofan engines rated at more than 55,000 pounds of thrust in full afterburner. The aircraft is 215 feet, 6 inches long and 42 feet, 2 inches high with a wingspan of 94 feet, 6 inches. The aircraft is constructed mostly of light aluminum alloy with titanium and stainless steel on the leading edges, elevons, rudder, and the under-surface of the rear fuselage.

Knowledge-based development of chromatographic separation processes requires efficient techniques to determine the physicochemical properties of the product and the impurities to be removed. These characterization techniques are usually divided into approaches that determine molecular properties, such as charge, hydrophobicity and size, or molecular interactions with auxiliary materials, commonly in the form of adsorption isotherms. In this study we demonstrate the application of a three-dimensional liquid chromatography approach to a clarified cell homogenate containing a therapeutic enzyme. Each separation dimension determines a molecular property relevant to the chromatographic behavior of each component. Matching of the peaks across the different separation dimensions and against a high-resolution reference chromatogram allows to assign the determined parameters to pseudo-components, allowing to determine the most promising technique for the removal of each impurity. More detailed process design using mechanistic models requires isotherm parameters. For this purpose, the second dimension consists of multiple linear gradient separations on columns in a high-throughput screening compatible format, that allow regression of isotherm parameters with an average standard error of 8%. © 2016 American Institute of Chemical Engineers Biotechnol.

Interactions between protein molecules and the virus removal membrane surface: Effects of immunoglobulin G adsorption and conformational changes on filter performance.

Membrane fouling commonly occurs in all filter types during virus filtration in protein-based biopharmaceutical manufacturing. Mechanisms of decline in virus filter performance due to membrane fouling were investigated using a cellulose-based virus filter as a model membrane. Filter performance was critically dependent on solution conditions; specifically, ionic strength. To understand the interaction between immunoglobulin G (IgG) and cellulose, sensors coated with cellulose were fabricated for surface plasmon resonance and quartz crystal microbalance with energy dissipation measurements. The primary cause of flux decline appeared to be irreversible IgG adsorption on the surface of the virus filter membrane. In particular, post-adsorption conformational changes in the IgG molecules promoted further irreversible IgG adsorption, a finding that could not be adequately explained by DLVO theory. Analyses of adsorption and desorption and conformational changes in IgG molecules on cellulose surfaces mimicking cellulose-based virus removal membranes provide an effective approach for identifying ways of optimizing solution conditions to maximize virus filter performance. © 2017 American Institute of Chemical Engineers Biotechnol.

Charged polysaccharides are used in the food industry, as cosmetics, and as vaccines. The viscosity, thermodynamics, and hydrodynamic properties of these charged polysaccharides are known to be strongly dependent on the solution ionic strength because of both inter- and intramolecular electrostatic interactions. The goal of this work was to quantitatively describe the effect of these electrostatic interactions on the ultrafiltration behavior of several charged capsular polysaccharides obtained from Streptococcus pneumoniae and used in the production of Pneumococcus vaccines. Ultrafiltration data were obtained using various Biomax™ polyethersulfone membranes with different nominal molecular weight cutoffs. Polysaccharide transmission decreased with decreasing ionic strength primarily because of the expansion of the charged polysaccharide associated with intramolecular electrostatic repulsion. Data were in good agreement with a simple theoretical model based on solute partitioning in porous membranes, with the effective size of the different polysaccharide serotypes evaluated using size exclusion chromatography at the same ionic conditions. These results provide fundamental insights and practical guidelines for exploiting the effects of electrostatic interactions during the ultrafiltration of charged polysaccharides. © 2016 American Institute of Chemical Engineers Biotechnol.

Minorities Road to Graduate School: The Xavier Experience

NASA Astrophysics Data System (ADS)

Sunda-Meya, Anderson

2010-10-01

During the past decade, Xavier University of Louisiana has ranked first nationally in the number of African American students who have earned undergraduate degrees in biology, chemistry, physics, and the physical sciences overall. Recent data shows that Xavier also ranks 8th in the nation in producing African American students who go on to earn science and engineering PhDs. A look at Xavier's ``way'' will examine several components that contribute to its success: pre-college preparation, recruitment programs, admissions policies, financial assistance, and academic monitoring programs. By promoting comprehensive recruitment and retention strategies and by leveling the playing field, Xavier experience may offer a paradigm and a model for increasing the pool of motivated, talented and well-prepared minority applicants ready to tackle the rigors of a graduate level education in physics.

This book is an institutional history of the NASA Lewis Research Center, located in Cleveland, Ohio, from 1940, when Congress authorized funding for a third laboratory for the National Advisory Committee for Aeronautics, through the 1980s. The history of the laboratory is discussed in relation to the development of American propulsion technology, with particular focus on the transition in the 1940s from the use of piston engines in airplanes to jet propulsion and that from air-breathing engines to rocket technology when the National Aeronautics and Space Administration was established in 1958. The personalities and research philosophies of the people who shaped the history of the laboratory are discussed, as is the relationship of Lewis Research Center to the Case Institute of Technology.

Finding the right material for the job is an important aspect of engineering. Sometimes the choice is as fundamental as selecting between steel and aluminum. Other times, the choice may be between different compositions in an alloy. Discovering and compiling materials data is a demanding task, but it leads to accurate models for analysis and successful materials application. Mat. DB. is a database management system designed for maintaining information on the properties and processing of engineered materials, including metals, plastics, composites, and ceramics. It was developed by the Center for Materials Data of American Society for Metals (ASM) International. The ASM Center for Materials Data collects and reviews material property data for publication in books, reports, and electronic database. Mat. DB was developed to aid the data management and material applications.

Female peer mentors early in college increase women’s positive academic experiences and retention in engineering

PubMed Central

Dasgupta, Nilanjana

2017-01-01

Scientific and engineering innovation is vital for American competitiveness, quality of life, and national security. However, too few American students, especially women, pursue these fields. Although this problem has attracted enormous attention, rigorously tested interventions outside artificial laboratory settings are quite rare. To address this gap, we conducted a longitudinal field experiment investigating the effect of peer mentoring on women’s experiences and retention in engineering during college transition, assessing its impact for 1 y while mentoring was active, and an additional 1 y after mentoring had ended. Incoming women engineering students (n = 150) were randomly assigned to female or male peer mentors or no mentors for 1 y. Their experiences were assessed multiple times during the intervention year and 1-y postintervention. Female (but not male) mentors protected women’s belonging in engineering, self-efficacy, motivation, retention in engineering majors, and postcollege engineering aspirations. Counter to common assumptions, better engineering grades were not associated with more retention or career aspirations in engineering in the first year of college. Notably, increased belonging and self-efficacy were significantly associated with more retention and career aspirations. The benefits of peer mentoring endured long after the intervention had ended, inoculating women for the first 2 y of college—the window of greatest attrition from science, technology, engineering, and mathematics (STEM) majors. Thus, same-gender peer mentoring for a short period during developmental transition points promotes women’s success and retention in engineering, yielding dividends over time. PMID:28533360

Angeli, David; De Leenheer, Patrick; Sontag, Eduardo D

2009-01-01

Certain mass-action kinetics models of biochemical reaction networks, although described by nonlinear differential equations, may be partially viewed as state-dependent linear time-varying systems, which in turn may be modeled by convex compact valued positive linear differential inclusions. A result is provided on asymptotic stability of such inclusions, and applied to a ubiquitous biochemical reaction network with inflows and outflows, known as the futile cycle. We also provide a characterization of exponential stability of general homogeneous switched systems which is not only of interest in itself, but also plays a role in the analysis of the futile cycle. 2009 American Institute of Chemical Engineers

Biorecovery is emerging as a promising process to retrieve gold from secondary resources. The present study aimed to explore the uptake pattern of Pycnoporus sanguineus biomass for gold, identify the effective functional groups in gold recovery process, and thus further intensify the process via microbial surface modification. Results showed that P. sanguineus biomass could effectively recover gold with the formation of highly crystal AuNPs without any exogeneous electron donor. Under the conditions of various initial gold concentrations (1.0, 2.0, and 3.0 mM), biomass dosage of 2.0 g/L, solution pH value of 4.0, and incubation temperature of 30°C, the uptake equilibrium established after 4, 8, and 12 h, respectively. The uptake process could be well described by pseudo-second order kinetics model (R 2  = 0.9988) and Langmuir isotherm model (R 2  = 0.9958). The maximum uptake capacity of P. sanguineus reached as high as 358.69 mg/g. Further analysis indicated that amino, carboxyl and hydroxyl groups positively contributed to the uptake process. Among them, amino group significantly favored the uptake of gold during recovery process. When P. sanguineus biomass was modified by introduction of amino group, the gold uptake process was successfully intensified by shortening the uptake period and enhancing the uptake capacity. © 2017 American Institute of Chemical Engineers Biotechnol.

The American Institute of Aeronautics and Astronautics has initiated a committee on standards for Artificial Intelligence. Presented are the initial efforts of one of the working groups of that committee. A candidate model is presented for the development life cycle of knowledge based systems (KBSs). The intent is for the model to be used by the aerospace community and eventually be evolved into a standard. The model is rooted in the evolutionary model, borrows from the spiral model, and is embedded in the standard Waterfall model for software development. Its intent is to satisfy the development of both stand-alone and embedded KBSs. The phases of the life cycle are shown and detailed as are the review points that constitute the key milestones throughout the development process. The applicability and strengths of the model are discussed along with areas needing further development and refinement by the aerospace community.

Stem cell-based approaches offer great application potential in tissue engineering and regenerative medicine owing to their ability of sensing the microenvironment and respond accordingly (dynamic behavior). Recently, the combination of nanobiomaterials with stem cells has paved a great way for further exploration. Nanobiomaterials with engineered surfaces could mimic the native microenvironment to which the seeded stem cells could adhere and migrate. Surface functionalized nanobiomaterial-based scaffolds could then be used to regulate or control the cellular functions to culture stem cells and regenerate damaged tissues or organs. Therefore, controlling the interactions between nanobiomaterials and stem cells is a critical factor. However, surface functionalization or modification techniques has provided an alternative approach for tailoring the nanobiomaterials surface in accordance to the physiological surrounding of a living cells; thereby, enhancing the structural and functional properties of the engineered tissues and organs. Currently, there are a variety of methods and technologies available to modify the surface of biomaterials according to the specific cell or tissue properties to be regenerated. This review highlights the trends in surface modification techniques for nanobiomaterials and the biological relevance in stem cell-based tissue engineering and regenerative medicine. © 2016 American Institute of Chemical Engineers Biotechnol.

Since 1964, NASA has supported a program of summer faculty fellowships for engineering and science educators. In a series of collaborations between NASA research and development centers and nearby universities, engineering faculty members spend 10 or 11 weeks working with professional peers on research. The Summer Faculty Program Committee of the American Society for Engineering Education supervises the programs. Objectives: (1) to further the professional knowledge of qualified engineering and science faculty members; (2) to stimulate and exchange ideas between participants and NASA; (3) to enrich and refresh the research and teaching activities of participants' institutions; (4) to contribute to the research objectives of the NASA center. Program Description: College or university faculty members were appointed as Research Fellows to spend 10 weeks in cooperative research and study at the NASA Langley Research Center. The Fellow devoted approximately 90 percent of the time to a research problem and the remaining time to a study program. The study program consisted of lectures and seminars on topics of interest or that are directly relevant to the Fellows' research topic.

Engineering approaches to energy balance and obesity: opportunities for novel collaborations and research: report of a joint national science foundation and national institutes of health workshop.

Energy balance disorders account for a large public health burden. The obesity epidemic in particular is one of the most rapidly evolving public health problems of our day. At present, two-thirds of American adults and one-sixth of American children and adolescents are considered either overweight or obese. Public health concern about obesity is high because of the increased risk and increased mortality of cardiovascular disease, Type 2 diabetes, many forms of cancer, gallbladder disease, and osteoarthritis. These risks increase with the severity of the obesity. Excess adipose tissue, representing fat storage, ultimately derives from an imbalance between energy intake and energy expenditure. Conversely, undesirable and inadvertent loss of body weight and muscle mass, as seen in aging and cachectic states of chronic diseases such as heart failure and cancer, have serious clinical and functional consequences without satisfactory clinical or behavioral solutions. Innovative engineering technologies could help to address unresolved problems in energy balance, intake, and expenditure. Novel sensors, devices, imaging technologies, nanotechnologies, biomaterials, technologies to detect biochemical markers of energy balance, mathematical modeling, systems biology, and other approaches could be developed, evaluated, and leveraged through multidisciplinary collaborations. Engineers, physical scientists, and mathematicians can work with scientists from other relevant disciplines who possess expertise in obesity and nutrition. Furthermore, the possibility of re-engineering the "built environment" to encourage higher levels of physical activity has been suggested as another promising and important approach to which engineers can contribute (see http://www.obesityresearch.nih.gov). Ultimately, systematic application of the "Engineering Approach" can help in developing the needed technologies and tools to facilitate research and eventually support therapeutic advances and behavioral change. This article summarizes important public health concerns related to disordered energy balance and describes research priorities identified at a recent National Science Foundation-National Institutes of Health workshop. Research funding opportunities are described as posted on the NIH Guide to Grants and Contracts (see http://www.nih.gov/grants/guide).

Minority American Women Physicists Achieving at the Intersection of Race and Gender

NASA Astrophysics Data System (ADS)

Horton, K. Renee

2005-10-01

As minority women physicists, we stand at the intersection of race and gender. We are physicists to be sure, but we are also women of Native, African, Hispanic, and Asian descent. We are colleagues, mothers, sisters, friends and wives, as are our white counterparts, but our experiences cannot be distilled to only gender or race. As Prudence Carter (2005 Annual Meeting of the American Educational Research Association) and Scott Page (``The Logic of Diversity,'' private communication, 2004) remind us, women of color emerge from the interaction between race and gender. This distinction is important because most researchers who study American women's participation in science focus exclusively on the participation of white American women. Of those who acknowledge the existence of non-white women, most do so by disclaiming the exclusion of women of color because the numbers are so small or the experiences are different from white American women. There are some important differences, however. While American women are 15% of all scientists and engineers, black American women are 60% of all black scientists and engineers. Yet an average of less than 3 black women and less than 3 Hispanic women earn PhDs in the U.S. each year, out of about 1100. As Rachel Ivie and Kim Nies Ray point out in AIP Publication R-430.02, ``Minority women especially represent a great, untapped resource that could be drawn on to increase the size of the scientific workforce in the U.S.'' Donna Nelson's (University of Oklahoma) study of diversity in science and engineering faculties further finds that (with the exception of one black woman in astronomy) there are no female black or Native American full professors. In physics, there are no black women professors and no Native American women professors. Despite such a bleak picture, there is hope. Of the 18 departments that award at least 40% of bachelors degrees to women, 7 are in Historically Black Colleges and Universities (HBCUs). Black women are earning degrees from HBCUs at rates above equity, and many singles and firsts at predominantly white institutions continue to persevere despite the obstacles.

Achieving Energy Savings in Municipal Construction in Long Beach, CA

DOE Office of Scientific and Technical Information (OSTI.GOV)

Parrish, Kristen; Regnier, Cindy

Long Beach Gas and Oil (LBGO), the public gas utility in Long Beach, California, partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to build a new, low-energy modular office building that is at least 50% below requirements set by Energy Standard 90.1-2007 of the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI), and the Illuminating Engineering Society of America (IESNA) as part of DOE’s Commercial Building Partnerships (CBP) program.3 The LBGO building, which demonstrates that modular construction can be very energy efficient, is expected to exceed the ASHRAEmore » baseline by about 45%. The new 15,000-square foot (ft2) LBGO office building has two stories and houses private offices, open-plan cubicle offices, and a conference room and call center on the second floor. The building’s modular nature allowed LBGO to realize the cost benefits of fasttracked construction while saving substantial energy and reducing operational costs. The project was funded by the utility’s ratepayer revenue, which imposed a tight budget limit. The design process was a collaborative effort involving LBGO and its design-build team, Lawrence Berkeley National Laboratory (Berkeley Lab), and subcontractors Stantec (formerly Burt Hill) and LHB Inc. The team proposed efficiency measures based on computer modeling of the building in full compliance with ASHRAE 90.1-2007; in the modeled building, the lighting and cooling systems were the largest energy users, so increasing the efficiency of these systems was a top priority. Promising measures were modeled to estimate their energy performance, and each measure was evaluated for its feasibility within the budget.« less

Female and male Hispanic students majoring in science or engineering: Their stories describing their educational journeys

NASA Astrophysics Data System (ADS)

Brown, Susan Wightman

National statistics clearly demonstrate an underrepresentation of minorities in the fields of science and engineering. Blacks, Hispanics, American Indians, and Asians do not typically choose science or engineering as their college major; therefore, there is a very small representation of these minorities in the science and engineering labor force. The decision not to major in science and engineering may begin as soon as the child can begin to recognize role models in the media. News stories, magazine articles, television programs, teachers, parents, administrators, and other agencies have painted the picture of a scientist or engineer as being dominantly a White male. Schools have continued society's portrayal by using curriculum, textbooks, role models, instructional strategies, and counseling that continues to encourage the White male to succeed in science and engineering, but discourages the minority students, male and female, from succeeding in these fields. In this qualitative study, 22 Hispanic students, 12 female and 10 male, who are majoring in science or engineering, were interviewed using Seidman's in-depth interviewing technique. These students were shadowed in their college science or engineering classes; their high school and college transcripts were analyzed; and, a focus group was brought together at the end of the interviewing process in order to allow interaction between the participants. The goal was to explore the educational journeys of the 22 Hispanic students. What made a difference in the journeys of these 22 students so that they could succeed in majors that have historically discouraged minority students? Seven themes emerged: family support, honors program, challenging and interactive curriculum, college preparation in high school courses, caring and kind teachers, small class size, and small communities. Gender comparison of the educational journeys documents these differences between the females and males: college preparation, mentoring, special school and summer programs, and gender role conflicts. In Chapter Six, a picture is painted by these 22 Hispanic students of a school that would promote success for all minority students in science and engineering related classes. Science and math educators, and really all educators, should take note and changes need to be made in our schools in order to provide a learning environment for all students.

Developing Technologies for Space Resource Utilization: Concept for a Planetary Engineering Research Institute

NASA Astrophysics Data System (ADS)

Blacic, J. D.; Dreesen, D.; Mockler, T.

2000-01-01

There are two principal factors that control the economics and ultimate utilization of space resources: 1) space transportation, and 2) space resource utilization technologies. Development of space transportation technology is driven by major government (military and civilian) programs and, to a lesser degree, private industry-funded research. Communication within the propulsion and spacecraft engineering community is aided by an effective independent professional organization, the American Institute of Aeronautics and Astronautics (AIAA). The many aerospace engineering programs in major university engineering schools sustain professional-level education in these fields. NASA does an excellent job of public education in space science and engineering at all levels. Planetary science, a precursor and supporting discipline for space resource utilization, has benefited from the establishment of the Lunar and Planetary Institute (LPI) which has served, since the early post-Apollo days, as a focus for both professional and educational development in the geosciences of the Moon and other planets. The closest thing the nonaerospace engineering disciplines have had to this kind of professional nexus is the sponsorship by the American Society of Civil Engineers of a series of space engineering conferences that have had a predominantly space resource orientation. However, many of us with long-standing interests in space resource development have felt that an LPI-like, independent institute was needed to focus and facilitate both research and education on the specific engineering disciplines needed to develop space resource utilization technologies on an on-going basis.

We fabricated novel tissue engineered urethral grafts using autologously harvested oral cells. We report their viability in a canine model. Oral tissues were harvested by punch biopsy and divided into mucosal and muscle sections. Epithelial cells from mucosal sections were cultured as epithelial cell sheets. Simultaneously muscle derived cells were seeded on collagen mesh matrices to form muscle cell sheets. At 2 weeks the sheets were joined and tubularized to form 2-layer tissue engineered urethras, which were autologously grafted to surgically induced urethral defects in 10 dogs in the experimental group. Tissue engineered grafts were not applied to the induced urethral defect in control dogs. The dogs were followed 12 weeks postoperatively. Urethrogram and histological examination were done to evaluate the grafting outcome. We successfully fabricated 2-layer tissue engineered urethras in vitro and transplanted them in dogs in the experimental group. The 12-week complication-free rate was significantly higher in the experimental group than in controls. Urethrogram confirmed urethral patency without stricture in the complication-free group at 12 weeks. Histologically urethras in the transplant group showed a stratified epithelial layer overlying well differentiated submucosa. In contrast, urethras in controls showed severe fibrosis without epithelial layer formation. Two-layer tissue engineered urethras were engineered using cells harvested by minimally invasive oral punch biopsy. Results suggest that this technique can encourage regeneration of a functional urethra. Copyright © 2012 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Electricity from fossil fuels without CO2 emissions: assessing the costs of carbon dioxide capture and sequestration in U.S. electricity markets.

PubMed

Johnson, T L; Keith, D W

2001-10-01

The decoupling of fossil-fueled electricity production from atmospheric CO2 emissions via CO2 capture and sequestration (CCS) is increasingly regarded as an important means of mitigating climate change at a reasonable cost. Engineering analyses of CO2 mitigation typically compare the cost of electricity for a base generation technology to that for a similar plant with CO2 capture and then compute the carbon emissions mitigated per unit of cost. It can be hard to interpret mitigation cost estimates from this plant-level approach when a consistent base technology cannot be identified. In addition, neither engineering analyses nor general equilibrium models can capture the economics of plant dispatch. A realistic assessment of the costs of carbon sequestration as an emissions abatement strategy in the electric sector therefore requires a systems-level analysis. We discuss various frameworks for computing mitigation costs and introduce a simplified model of electric sector planning. Results from a "bottom-up" engineering-economic analysis for a representative U.S. North American Electric Reliability Council (NERC) region illustrate how the penetration of CCS technologies and the dispatch of generating units vary with the price of carbon emissions and thereby determine the relationship between mitigation cost and emissions reduction.

Campus Climate and the Underrepresented Minority Engineering Student Experience: A Critical Race Study

NASA Astrophysics Data System (ADS)

Mayes, Terrance

In the current technological era, the number of minorities in science, technology, engineering, and mathematics (STEM) is a crucial factor in predetermining the economic growth of the United States. Since the minority population is growing at much faster rates than the non-minority population, the lack of proportionate production of minority engineers poses a threat to the United States' ability to remain a global competitor in technological innovation. Sixty-three per cent (63%) of undergraduate students who enter engineering majors continue on to graduate in that major. The graduation rate, however, for African-American, Hispanic, and Native-American students in engineering is significantly lower at 39%. As this group represents only a small fraction of the annual student enrollment, engineering programs are graduating these minority groups at rates that are greatly disproportionate to United States demographics. Therefore, researchers are thoroughly investigating certain initiatives that promote academic success among underrepresented minority students in engineering. Colleges and universities have attempted to address the growing achievement gap between underrepresented minority and non-minority engineering students, predominately through various deficit-based interventions, focusing on the student's flaws and problems. As the pipeline for minorities in engineering continues to narrow, it begs the question of whether institutions are focusing on the right solutions to the problem. Critical Race Theory scholars argue that colleges and universities must address institutional climate issues around students, such as racism, microaggressions, and marginalization, before members of oppressed groups can truly succeed. This dissertation explored the unique experiences of underrepresented minority engineering students in a predominately White and Asian campus.

Raman-based multivariate calibration models have been developed for real-time in situ monitoring of multiple process parameters within cell culture bioreactors. Developed models are generic, in the sense that they are applicable to various products, media, and cell lines based on Chinese Hamster Ovarian (CHO) host cells, and are scalable to large pilot and manufacturing scales. Several batches using different CHO-based cell lines and corresponding proprietary media and process conditions have been used to generate calibration datasets, and models have been validated using independent datasets from separate batch runs. All models have been validated to be generic and capable of predicting process parameters with acceptable accuracy. The developed models allow monitoring multiple key bioprocess metabolic variables, and hence can be utilized as an important enabling tool for Quality by Design approaches which are strongly supported by the U.S. Food and Drug Administration. © 2015 American Institute of Chemical Engineers.

Hydrogel-based three-dimensional cell culture for organ-on-a-chip applications.

Lee, Seung Hwan; Shim, Kyu Young; Kim, Bumsang; Sung, Jong Hwan

2017-05-01

Recent studies have reported that three-dimensionally cultured cells have more physiologically relevant functions than two-dimensionally cultured cells. Cells are three-dimensionally surrounded by the extracellular matrix (ECM) in complex in vivo microenvironments and interact with the ECM and neighboring cells. Therefore, replicating the ECM environment is key to the successful cell culture models. Various natural and synthetic hydrogels have been used to mimic ECM environments based on their physical, chemical, and biological characteristics, such as biocompatibility, biodegradability, and biochemical functional groups. Because of these characteristics, hydrogels have been combined with microtechnologies and used in organ-on-a-chip applications to more closely recapitulate the in vivo microenvironment. Therefore, appropriate hydrogels should be selected depending on the cell types and applications. The porosity of the selected hydrogel should be controlled to facilitate the movement of nutrients and oxygen. In this review, we describe various types of hydrogels, external stimulation-based gelation of hydrogels, and control of their porosity. Then, we introduce applications of hydrogels for organ-on-a-chip. Last, we also discuss the challenges of hydrogel-based three-dimensional cell culture techniques and propose future directions. © 2017 American Institute of Chemical Engineers Biotechnol.

Interests diffusion on a semantic multiplex. Comparing Computer Science and American Physical Society communities

NASA Astrophysics Data System (ADS)

D'Agostino, Gregorio; De Nicola, Antonio

2016-10-01

Exploiting the information about members of a Social Network (SN) represents one of the most attractive and dwelling subjects for both academic and applied scientists. The community of Complexity Science and especially those researchers working on multiplex social systems are devoting increasing efforts to outline general laws, models, and theories, to the purpose of predicting emergent phenomena in SN's (e.g. success of a product). On the other side the semantic web community aims at engineering a new generation of advanced services tailored to specific people needs. This implies defining constructs, models and methods for handling the semantic layer of SNs. We combined models and techniques from both the former fields to provide a hybrid approach to understand a basic (yet complex) phenomenon: the propagation of individual interests along the social networks. Since information may move along different social networks, one should take into account a multiplex structure. Therefore we introduced the notion of "Semantic Multiplex". In this paper we analyse two different semantic social networks represented by authors publishing in the Computer Science and those in the American Physical Society Journals. The comparison allows to outline common and specific features.

ASTM and ASME-BPE Standards--Complying with the Needs of the Pharmaceutical Industry.

PubMed

Huitt, William M

2011-01-01

Designing and building a pharmaceutical facility requires the owner, engineer of record, and constructor to be knowledgeable with regard to the industry codes and standards that apply to this effort. Up until 1997 there were no industry standards directed at the needs and requirements of the pharmaceutical industry. Prior to that time it was a patchwork effort at resourcing and adopting nonpharmaceutical-related codes and standards and then modifying them in order to meet the more stringent requirements of the Food and Drug Administration (FDA). In 1997 the American Society of Mechanical Engineers (ASME) published the first Bioprocessing Equipment (BPE) Standard. Through harmonization efforts this relatively new standard has brought together, scrutinized, and refined industry accepted methodologies together with FDA compliance requirements, and has established an American National Standard that provides a comprehensive set of standards that are integral to the pharmaceutical industry. This article describes various American National Standards, including those developed and published by the American Society for Testing and Materials (ASTM), and how they apply to the pharmaceutical industry. It goes on to discuss the harmonization effort that takes place between the various standards developers in an attempt to prevent conflicts and omissions between the many standards. Also included are examples of tables and figures taken from the ASME-BPE Standard. These examples provide the reader with insight to the relevant content of the ASME-BPE Standard.

In 1997 the American Society of Mechanical Engineers (ASME) published the first Bioprocessing Equipment (BPE) Standard. In its initial development and ongoing maintenance it works with other American National Standards developers to harmonize the many standards associated with the design, engineering, and construction of bioprocessing facilities. This harmonization effort has established a comprehensive set of standards for the betterment of the pharmaceutical industry at large. This effort is, and will remain, very important as technology, along with new and improved product and processes, evolve into the future.

Giving back or giving up: Native American student experiences in science and engineering.

Native Americans are underrepresented in science, technology, engineering, and math (STEM) careers. We examine communal goal incongruence-the mismatch between students' emphasis on communal work goals and the noncommunal culture of STEM-as a possible factor in this underrepresentation. First, we surveyed 80 Native American STEM freshmen and found they more highly endorsed communal goals than individualistic work goals. Next, we surveyed 96 Native American and White American students in STEM and non-STEM majors and confirmed that both Native American men and women in STEM highly endorsed communal goals. In a third study, we conducted a follow-up survey and in-depth interviews with a subset of Native American STEM students in their second semester to assess their experiences of belonging uncertainty, intrinsic motivation, persistence intentions, and perceived performance in STEM as a function of their initial communal work goals. Results demonstrate the prominence of communal goals among incoming Native American freshman (especially compared with White male STEM majors) and the connection between communal goals and feelings of belonging uncertainty, low motivation, and perceived poor performance 1 semester later. The interview data illustrate that these issues are particularly salient for students raised within tribal communities, and that a communal goal orientation is not just a vague desire to "help others," but a commitment to helping their tribal communities. The interviews also highlight the importance of student support programs for fostering feelings of belonging. We end by discussing implications for interventions and institutional changes that may promote Native American student retention in STEM.

Experiences of African American Young Women in Science, Technology, Engineering, and Mathematics (STEM) Education

NASA Astrophysics Data System (ADS)

Kolo, Yovonda Ingram

African American women are underrepresented in science, technology, engineering, and mathematics (STEM) fields throughout the United States. As the need for STEM professionals in the United States increases, it is important to ensure that African American women are among those professionals making valuable contributions to society. The purpose of this phenomenological study was to describe the experiences of African American young women in relation to STEM education. The research question for this study examined how experiences with STEM in K-10 education influenced African American young women's academic choices in their final years in high school. The theory of multicontextuality was used to provide the conceptual framework. The primary data source was interviews. The sample was composed of 11 African American young women in their junior or senior year in high school. Data were analyzed through the process of open coding, categorizing, and identifying emerging themes. Ten themes emerged from the answers to research questions. The themes were (a) high teacher expectations, (b) participation in extra-curricular activities, (c) engagement in group-work, (d) learning from lectures, (e) strong parental involvement, (f) helping others, (g) self-efficacy, (h) gender empowerment, (i) race empowerment, and (j) strategic recruitment practices. This study may lead to positive social change by adding to the understanding of the experiences of African American young women in STEM. By doing so, these findings might motivate other African American young women to pursue advanced STEM classes. These findings may also provide guidance to parents and educators to help increase the number of African American women in STEM.

Moving Toward an Anti-Deficit Perspective: African American Science, Technology, Engineering, Mathematics (STEM) Students at Hispanic-Serving Institutions (HSI)

NASA Astrophysics Data System (ADS)

Mahoney, Melissa M.

The increased demand for qualified STEM workers, necessitates addressing the bachelor's science, technology, engineering and mathematics (STEM) degree achievement among African Americans and other underrepresented populations. Using inquiry derived from Harper's (2010) Anti-Deficit Achievement Framework, this study sought to explore the factors that contribute to the successful degree completion of African American STEM students within a large comprehensive university system. Coding of the twelve semi-structured interviews revealed six major themes: a) K-12/precollege educational experiences, b) motivation to complete a STEM degree, c) systems of social support, d) extracurricular activities and out-of-class experiences, e) addressing stereotyping and discrimination, and f) faculty behaviors and dispositions. All themes were intertwined at each phase of participants' academic careers, thereby, highlighting the complexity of this population's experience and what is needed to address their low STEM degree attainment. Findings indicated that this student population benefits from positive, sustained faculty-student interactions, holistic STEM success programming, and genuine networks of social support. Furthermore, Harper's framework can be modified to explore the motivation of African American STEM students as well as the African American student's relationship with disability support services.

The current study used a case study methodological approach, including document analysis, semistructured interviews, and participant observations, to investigate how a science, technology, engineering, and mathematics (STEM) enrichment program supported retention and degree attainment of underrepresented students at a large, public, predominantly white institution. From this study, a model emerged that encompassed four components: proactive care, holistic support, community building, and catalysts for STEM identity development. These components encompassed a number of strategies and practices that were instrumental in the outcomes of program participants. This paper concludes with implications for practice, such as using models to inform program planning, assessment, and evaluation. © 2016 T. B. Lane.

CAPE CANAVERAL, Fla. -- NASA managers at NASA's Kennedy Space Center in Florida show off the Florida Project of the Year trophies that the crawlerway system evaluation team received from the American Society of Civil Engineers (ASCE). From left are Michael Benik, director of Center Operations; Pepper Phillips, manager of the 21st Century Ground Systems Program Office; and Russell Romanella, associate director for Engineering and Technical Operations. The Cape Canaveral branch of the ASCE nominated the team for its project, the Crawlerway Evaluation to Support a Heavy-Lift Program. The crawlerway is a 130-foot-wide, specialty-built roadway between Kennedy's Vehicle Assembly Building (VAB), where rockets and spacecraft are prepared for flight, and Launch Pad 39A and 39B. The team's more than two-year evaluation confirmed the crawlerway system would be able to support the weight of moving the agency's future heavy-lift rockets and potential commercial vehicles from the VAB to the launch pads. The award honors the team's outstanding engineering efforts in research, design, construction and management, recognizing the complexity of multi-agency coordination and cost-effective engineering advances.

Advancing structural and functional maturation of stem cell-derived cardiomyocytes remains a key challenge for applications in disease modeling, drug screening, and heart repair. Here, we sought to advance cardiomyocyte maturation in engineered human myocardium (EHM) toward an adult phenotype under defined conditions. We systematically investigated cell composition, matrix, and media conditions to generate EHM from embryonic and induced pluripotent stem cell-derived cardiomyocytes and fibroblasts with organotypic functionality under serum-free conditions. We used morphological, functional, and transcriptome analyses to benchmark maturation of EHM. EHM demonstrated important structural and functional properties of postnatal myocardium, including: (1) rod-shaped cardiomyocytes with M bands assembled as a functional syncytium; (2) systolic twitch forces at a similar level as observed in bona fide postnatal myocardium; (3) a positive force-frequency response; (4) inotropic responses to β-adrenergic stimulation mediated via canonical β 1 - and β 2 -adrenoceptor signaling pathways; and (5) evidence for advanced molecular maturation by transcriptome profiling. EHM responded to chronic catecholamine toxicity with contractile dysfunction, cardiomyocyte hypertrophy, cardiomyocyte death, and N-terminal pro B-type natriuretic peptide release; all are classical hallmarks of heart failure. In addition, we demonstrate the scalability of EHM according to anticipated clinical demands for cardiac repair. We provide proof-of-concept for a universally applicable technology for the engineering of macroscale human myocardium for disease modeling and heart repair from embryonic and induced pluripotent stem cell-derived cardiomyocytes under defined, serum-free conditions. © 2017 American Heart Association, Inc.

Genome-scale flux balance analysis (FBA) is a powerful systems biology tool to characterize intracellular reaction fluxes during cell cultures. FBA estimates intracellular reaction rates by optimizing an objective function, subject to the constraints of a metabolic model and media uptake/excretion rates. A dynamic extension to FBA, dynamic flux balance analysis (DFBA), can calculate intracellular reaction fluxes as they change during cell cultures. In a previous study by Read et al. (2013), a series of informed amino acid supplementation experiments were performed on twelve parallel murine hybridoma cell cultures, and this data was leveraged for further analysis (Read et al., Biotechnol Prog. 2013;29:745-753). In order to understand the effects of media changes on the model murine hybridoma cell line, a systems biology approach is applied in the current study. Dynamic flux balance analysis was performed using a genome-scale mouse metabolic model, and multivariate data analysis was used for interpretation. The calculated reaction fluxes were examined using partial least squares and partial least squares discriminant analysis. The results indicate media supplementation increases product yield because it raises nutrient levels extending the growth phase, and the increased cell density allows for greater culture performance. At the same time, the directed supplementation does not change the overall metabolism of the cells. This supports the conclusion that product quality, as measured by glycoform assays, remains unchanged because the metabolism remains in a similar state. Additionally, the DFBA shows that metabolic state varies more at the beginning of the culture but less by the middle of the growth phase, possibly due to stress on the cells during inoculation. © 2016 American Institute of Chemical Engineers Biotechnol.

To characterize the extent and thickness of lithologic units that may have differing scour potential, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, has performed several geoelectrical surveys of the lower American River channel and flood plain between Cal Expo and the Rio Americano High School in east Sacramento, California. Additional geotechnical data have been collected by the U.S. Army Corps of Engineers and its contractors. Data resulting from these surveys have been compiled into similar database formats and converted to uniform geospatial datums and projections. These data have been visualized in a digital three-dimensional framework project that can be viewed using freely available software. These data facilitate a comprehensive analysis of the resistivity structure underlying the lower American River corridor and assist in levee system management.

Until the recent dissolution of the Soviet Union, the Communist Party exerted a strict control of access to and dissemination of scientific and technical information (STI). This article presents models of the Soviet-style information society and the Western-style information society and discusses the effects of centralized governmental control of information on Russian technical communication practices. The effects of political control on technical communication are then used to interpret the results of a survey of Russian and U.S. aerospace engineers and scientists concerning the time devoted to technical communication, their collaborative writing practices and their attitudes toward collaboration, the kinds of technical documents they produce and use, their views regarding the appropriate content for an undergraduate technical communication course, and their use of computer technology. Finally, the implications of these findings for future collaboration between Russian and U.S. engineers and scientists are examined.

An interdisciplinary team with expertise in coastal and port engineering, coastal management, environmental science, anthropology, emergency management, and mitigation visited Samoa and American Samoa in late October and November, 2009. The team, sponsored by ASCE/COPRI, EERI, and the NTHMP focused on identifying the factors which effected the impacts of the September 29, 2009 tsunami. The engineering group assessed the value of engineered coastal protection and natural protective features (reefs, mangroves, etc.) in reducing tsunami inundation by comparing protected and unprotected coastlines and examined possible correlations between damage to the built environment and hydrodynamic forcing, namely loading by runup and velocity. The EERI group looked at how coastal land use planning and management, emergency planning and response, and culture, education and awareness of tsunami hazards affected outcomes. The group also looked at public response to the natural warnings of September 29 and the official warnings following the October 7 Vanuatu tsunami warning.

Dragonfly - NASA and the Crisis Aboard MIR (New York: HarperCollins Publishers), the story of the Russian-American misadventures on MIR. An expose with almost embarrassing detail about the inner-workings of Johnson Space Center in Houston, this book is best read with the JSC organization chart in hand. Here's the real world of engineering and life in extreme environments. It makes most other accounts of "requirements analysis" appear glib and simplistic. The book vividly portrays the sometimes harrowing experiences of the American astronauts in the web of Russian interpersonal relations and literally in the web of MIR's wiring. Burrough's exposition reveals how handling bureaucratic procedures and bulky facilities is as much a matter of moxie and goodwill as technical capability. Lessons from MIR showed NASA that getting to Mars required a different view of knowledge and improvisation-long-duration missions are not at all like the scripted and pre-engineered flights of Apollo or the Space Shuttle.

American Indian Science & Engineering Society (AISES) Programs: Outreach to Native Americans

NASA Astrophysics Data System (ADS)

Lacourse, S.

2003-12-01

AISES is a national non-profit organization which nurtures building of community by bridging science and technology with traditional Native values. Through its educational programs, AISES provides opportunities for American Indians and Native Alaskans to pursue studies in science, engineering, and technology arenas. The trained professionals then become technologically informed leaders within the Indian community. AISES' ultimate goal is to be a catalyst for the advancement of American Indians and Native Alaskans as they seek to become self-reliant and self-determined members of society. AISES' Higher Education Program consists of scholarships, college relations, leadership development, and internships. This session will focus on the value and impact of AISES internships for AISES students, including hands-on experience in the student's field of study, co-op opportunities, and entrance into graduate school. AISES currently offers internship placements with NASA-Goddard Space Flight Center, the U.S. State Department, the Departments of Commerce and Veterans Affairs, and the Centers for Disease Control and Prevention. In 2004, AISES will also be offering placements at the Central Intelligence Agency.

Intervention to Improve Engineering Self-Efficacy and Sense of Belonging of First-Year Engineering Students

NASA Astrophysics Data System (ADS)

Jordan, Kari L.

The percentage of bachelor's degrees in STEM awarded to women and underrepresented minority students needs to increase dramatically to reach parity with their majority counterparts. While three key underrepresented minority (URM) groups, African Americans, Hispanic/Latinos, and Native Americans constitute some 30 percent of the overall undergraduate student population in the United States, the share of engineering degrees earned by members of these groups declines as degree level increases. Underrepresented minority students accounted for about 12% of engineering bachelor's degrees awarded in 2009, 7% of master's degrees and 3% of doctorates (NSF Science Resource Statistics, 2009). The percent in engineering has been steadily decreasing, while overall participation in higher education among these groups has increased considerably. Keeping those thoughts in mind it is important to examine the historical theories and frameworks that will help us not only understand why underrepresented minority students pursue and persist in STEM majors in low numbers, but to also develop interventions to improve the alarming statistics that hamper engineering diversity. As indicated by our past two U.S. Presidents, there has been an increased discussion on the national and state level regarding the number of students entering engineering disciplines in general and underrepresented minority students in particular. Something happens between a student's freshman year and the point they decide to either switch their major or drop out of school altogether. Some researchers attribute the high dropout rate of underrepresented minority students in engineering programs to low engineering self-efficacy (e.g. Jordan et al., 2011). A student's engineering self-efficacy is his/her belief that he/she can successfully navigate the engineering curriculum and eventually become a practicing engineer. A student's engineering self-efficacy is formed by mastery experiences, vicarious experiences, his/her physiological state, and social persuasions, such as student-professor interaction. Increasing the awareness of a student's engineering self-efficacy could potentially improve sense of belonging and persistence for underrepresented minority students in engineering. The hypothesis of this study is that an intervention during the first semester of an incoming freshman's tenure can help improve their engineering self-efficacy, sense of belonging, and overall retention in the engineering program. This study explored the following research questions: 1. What are the differences in engineering self-efficacy, and sense of belonging for first-year underrepresented minority engineering students compared to majority students? 2. What factors or variables should be considered and/or addressed in designing an intervention to increase engineering self-efficacy and sense of belonging amongst first-year underrepresented minority engineering students? 3. Can a small intervention during the beginning of the first semester improve a student's sense of belonging, engineering self-efficacy, and student-professor interaction? Using the race, social fit, and achievement study by Walton and Cohen as a model, the author developed an intervention consisting of short compelling videos of upperclass engineering students from diverse backgrounds. In these videos, students discussed their pursuit of the engineering degree, what obstacles they faced in terms of sense of belonging and coping efficacy, and how they overcame those obstacles. Treatment groups of students watched the videos during the first few weeks of the semester, and pre and post tests were administered to measure mean gains in the student's engineering self-efficacy, sense of belonging, and other variables. The results showed that underrepresented minority students had a lower sense of belonging than whites. The intervention used in the study contributed to mean gain increases in participants' engineering self-efficacy, which could ultimately improve persistence. A single intervention did not show a significant increase in students' sense of belonging; more work needs to be done to develop an effective intervention. The intervention is easily adaptable with insignificant cost, making it attractive for Minority Engineering Program (MEP) and other success program whose aim is to increase students' engineering self-efficacy.

A Longitudinal Study of How Quality Mentorship and Research Experience Integrate Underrepresented Minorities into STEM Careers.

PubMed

Estrada, Mica; Hernandez, Paul R; Schultz, P Wesley

2018-01-01

African Americans, Latinos, and Native Americans are historically underrepresented minorities (URMs) among science, technology, engineering, and mathematics (STEM) degree earners. Viewed from a perspective of social influence, this pattern suggests that URMs do not integrate into the STEM academic community at the same rate as non-URM students. Estrada and colleagues recently showed that Kelman's tripartite integration model of social influence (TIMSI) predicted URM persistence into science fields. In this paper, we longitudinally examine the integration of URMs into the STEM community by using growth-curve analyses to measure the development of TIMIS's key variables (science efficacy, identity, and values) from junior year through the postbaccalaureate year. Results showed that quality mentorship and research experience occurring in the junior and senior years were positively related to student science efficacy, identity, and values at that same time period. Longitudinal modeling of TIMSI further shows that, while efficacy is important, and perhaps a necessary predictor of moving toward a STEM career, past experiences of efficacy may not be sufficient for maintaining longer-term persistence. In contrast, science identity and values do continue to be predictive of STEM career pathway persistence up to 4 years after graduation. © 2018 M. Estrada et al.

The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most "gatekeeper" chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap. © 2015 B.

New biomaterials prepared from egg yolk and its main fractions (plasma and granules) have been developed for use in tissue engineering. Protein gels obtained via transglutaminase cross-linking were characterized by rheometry, texturometry and scanning electron microscopy. All the gels exhibited suitable physical and mechanical characteristics for use as potential biomaterials in skin regeneration. Specifically, results showed that these materials presented a compact, uniform structure, with granular gel being found to be the most resistant as well as the most elastic material. Accordingly, these gels were subsequently evaluated as scaffolds for murine fibroblast growth. The best results were obtained with granule gels. Not only adhesion and cell growth were detected when using these gels, but also continuous coatings of cells growing on their surface. These findings can be attributed to the higher protein content of this fraction and to the particular structure of its proteins. Thus, granules have proved to be an interesting potential raw material for scaffold development. © 2016 American Institute of Chemical Engineers Biotechnol.

2016-11-01

Biosynthesis of complex natural products like polyketides and nonribosomal peptides using Escherichia coli as a heterologous host provides an opportunity to access these molecules. The value in doing so stems from the fact that many compounds hold some therapeutic or other beneficial property and their original production hosts are intractable for a variety of reasons. In this work, metabolic engineering and induction variable optimization were used to increase production of the polyketide-nonribosomal peptide compound yersiniabactin, a siderophore that has been utilized to selectively remove metals from various solid and aqueous samples. Specifically, several precursor substrate support pathways were altered through gene expression and exogenous supplementation in order to boost production of the final compound. The gene expression induction process was also analyzed to identify the temperatures and inducer concentrations resulting in highest final production levels. When combined, yersiniabactin production was extended to ∼175 mg L -1 . © 2016 American Institute of Chemical Engineers Biotechnol.

Cultural stereotypes as gatekeepers: increasing girls' interest in computer science and engineering by diversifying stereotypes.

Cheryan, Sapna; Master, Allison; Meltzoff, Andrew N

2015-01-01

Despite having made significant inroads into many traditionally male-dominated fields (e.g., biology, chemistry), women continue to be underrepresented in computer science and engineering. We propose that students' stereotypes about the culture of these fields-including the kind of people, the work involved, and the values of the field-steer girls away from choosing to enter them. Computer science and engineering are stereotyped in modern American culture as male-oriented fields that involve social isolation, an intense focus on machinery, and inborn brilliance. These stereotypes are compatible with qualities that are typically more valued in men than women in American culture. As a result, when computer science and engineering stereotypes are salient, girls report less interest in these fields than their male peers. However, altering these stereotypes-by broadening the representation of the people who do this work, the work itself, and the environments in which it occurs-significantly increases girls' sense of belonging and interest in the field. Academic stereotypes thus serve as gatekeepers, driving girls away from certain fields and constraining their learning opportunities and career aspirations.

Personalized glucose forecasting for type 2 diabetes using data assimilation

Albers, David J.; Gluckman, Bruce; Ginsberg, Henry; Hripcsak, George; Mamykina, Lena

2017-01-01

Type 2 diabetes leads to premature death and reduced quality of life for 8% of Americans. Nutrition management is critical to maintaining glycemic control, yet it is difficult to achieve due to the high individual differences in glycemic response to nutrition. Anticipating glycemic impact of different meals can be challenging not only for individuals with diabetes, but also for expert diabetes educators. Personalized computational models that can accurately forecast an impact of a given meal on an individual’s blood glucose levels can serve as the engine for a new generation of decision support tools for individuals with diabetes. However, to be useful in practice, these computational engines need to generate accurate forecasts based on limited datasets consistent with typical self-monitoring practices of individuals with type 2 diabetes. This paper uses three forecasting machines: (i) data assimilation, a technique borrowed from atmospheric physics and engineering that uses Bayesian modeling to infuse data with human knowledge represented in a mechanistic model, to generate real-time, personalized, adaptable glucose forecasts; (ii) model averaging of data assimilation output; and (iii) dynamical Gaussian process model regression. The proposed data assimilation machine, the primary focus of the paper, uses a modified dual unscented Kalman filter to estimate states and parameters, personalizing the mechanistic models. Model selection is used to make a personalized model selection for the individual and their measurement characteristics. The data assimilation forecasts are empirically evaluated against actual postprandial glucose measurements captured by individuals with type 2 diabetes, and against predictions generated by experienced diabetes educators after reviewing a set of historical nutritional records and glucose measurements for the same individual. The evaluation suggests that the data assimilation forecasts compare well with specific glucose measurements and match or exceed in accuracy expert forecasts. We conclude by examining ways to present predictions as forecast-derived range quantities and evaluate the comparative advantages of these ranges. PMID:28448498

Construction and Optimization of a Heterologous Pathway for Protocatechuate Catabolism in Escherichia coli Enables Bioconversion of Model Aromatic Compounds.

The production of biofuels from lignocellulose yields a substantial lignin by-product stream that currently has few applications. Biological conversion of lignin-derived compounds into chemicals and fuels has the potential to improve the economics of lignocellulose-derived biofuels, but few microbes are able both to catabolize lignin-derived aromatic compounds and to generate valuable products. While Escherichia coli has been engineered to produce a variety of fuels and chemicals, it is incapable of catabolizing most aromatic compounds. Therefore, we engineered E. coli to catabolize protocatechuate, a common intermediate in lignin degradation, as the sole source of carbon and energy via heterologous expression of a nine-gene pathway from Pseudomonas putida KT2440. We next used experimental evolution to select for mutations that increased growth with protocatechuate more than 2-fold. Increasing the strength of a single ribosome binding site in the heterologous pathway was sufficient to recapitulate the increased growth. After optimization of the core pathway, we extended the pathway to enable catabolism of a second model compound, 4-hydroxybenzoate. These engineered strains will be useful platforms to discover, characterize, and optimize pathways for conversions of lignin-derived aromatics. IMPORTANCE Lignin is a challenging substrate for microbial catabolism due to its polymeric and heterogeneous chemical structure. Therefore, engineering microbes for improved catabolism of lignin-derived aromatic compounds will require the assembly of an entire network of catabolic reactions, including pathways from genetically intractable strains. Constructing defined pathways for aromatic compound degradation in a model host would allow rapid identification, characterization, and optimization of novel pathways. We constructed and optimized one such pathway in E. coli to enable catabolism of a model aromatic compound, protocatechuate, and then extended the pathway to a related compound, 4-hydroxybenzoate. This optimized strain can now be used as the basis for the characterization of novel pathways. Copyright © 2017 American Society for Microbiology.

Design considerations and challenges for mechanical stretch bioreactors in tissue engineering.

Lei, Ying; Ferdous, Zannatul

2016-05-01

With the increase in average life expectancy and growing aging population, lack of functional grafts for replacement surgeries has become a severe problem. Engineered tissues are a promising alternative to this problem because they can mimic the physiological function of the native tissues and be cultured on demand. Cyclic stretch is important for developing many engineered tissues such as hearts, heart valves, muscles, and bones. Thus a variety of stretch bioreactors and corresponding scaffolds have been designed and tested to study the underlying mechanism of tissue formation and to optimize the mechanical conditions applied to the engineered tissues. In this review, we look at various designs of stretch bioreactors and common scaffolds and offer insights for future improvements in tissue engineering applications. First, we summarize the requirements and common configuration of stretch bioreactors. Next, we present the features of different actuating and motion transforming systems and their applications. Since most bioreactors must measure detailed distributions of loads and deformations on engineered tissues, techniques with high accuracy, precision, and frequency have been developed. We also cover the key points in designing culture chambers, nutrition exchanging systems, and regimens used for specific tissues. Since scaffolds are essential for providing biophysical microenvironments for residing cells, we discuss materials and technologies used in fabricating scaffolds to mimic anisotropic native tissues, including decellularized tissues, hydrogels, biocompatible polymers, electrospinning, and 3D bioprinting techniques. Finally, we present the potential future directions for improving stretch bioreactors and scaffolds. © 2016 American Institute of Chemical Engineers Biotechnol.

Multiphasic scaffolds for periodontal tissue engineering.

Ivanovski, S; Vaquette, C; Gronthos, S; Hutmacher, D W; Bartold, P M

2014-12-01

For a successful clinical outcome, periodontal regeneration requires the coordinated response of multiple soft and hard tissues (periodontal ligament, gingiva, cementum, and bone) during the wound-healing process. Tissue-engineered constructs for regeneration of the periodontium must be of a complex 3-dimensional shape and adequate size and demonstrate biomechanical stability over time. A critical requirement is the ability to promote the formation of functional periodontal attachment between regenerated alveolar bone, and newly formed cementum on the root surface. This review outlines the current advances in multiphasic scaffold fabrication and how these scaffolds can be combined with cell- and growth factor-based approaches to form tissue-engineered constructs capable of recapitulating the complex temporal and spatial wound-healing events that will lead to predictable periodontal regeneration. This can be achieved through a variety of approaches, with promising strategies characterized by the use of scaffolds that can deliver and stabilize cells capable of cementogenesis onto the root surface, provide biomechanical cues that encourage perpendicular alignment of periodontal fibers to the root surface, and provide osteogenic cues and appropriate space to facilitate bone regeneration. Progress on the development of multiphasic constructs for periodontal tissue engineering is in the early stages of development, and these constructs need to be tested in large animal models and, ultimately, human clinical trials. © International & American Associations for Dental Research.

Estrogen inhibits lysyl oxidase and decreases mechanical function in engineered ligaments.

Women are more likely to suffer an anterior cruciate ligament (ACL) rupture than men, and the incidence of ACL rupture in women rises with increasing estrogen levels. We used an engineered ligament model to determine how an acute rise in estrogen decreases the mechanical properties of ligaments. Using fibroblasts isolated from human ACLs from male or female donors, we engineered ligaments and determined that ligaments made from female ACL cells had more collagen and were equal in strength to those made from male ACL cells. We then treated engineered ligaments for 14 days with low (5 pg/ml), medium (50 pg/ml), or high (500 pg/ml) estrogen, corresponding to the range of in vivo serum estrogen concentrations and found that collagen within the grafts increased without a commensurate increase in mechanical strength. Mimicking the menstrual cycle, with 12 days of low estrogen followed by 2 days of physiologically high estrogen, resulted in a decrease in engineered ligament mechanical function with no change in the amount of collagen in the graft. The decrease in mechanical stiffness corresponded with a 61.7 and 76.9% decrease in the activity of collagen cross-linker lysyl oxidase with 24 and 48 h of high estrogen, respectively. Similarly, grafts treated with the lysyl oxidase inhibitor β-aminoproprionitrile (BAPN) for 24 h showed a significant decrease in ligament mechanical strength [control (CON) = 1.58 ± 0.06 N; BAPN = 1.06 ± 0.13 N] and stiffness (CON = 7.7 ± 0.46 MPa; BAPN = 6.1 ± 0.71 MPa) without changing overall collagen levels (CON = 396 ± 11.5 μg; BAPN = 382 ± 11.6 μg). Together, these data suggest that the rise in estrogen during the follicular phase decreases lysyl oxidase activity in our engineered ligament model and if this occurs in vivo may decrease the stiffness of ligaments and contribute to the elevated rate of ACL rupture in women.

Involvement of African-American Girls in Science, Technology, Engineering, and Mathematics (STEM) Education

NASA Astrophysics Data System (ADS)

Nkere, Nsidi

A qualitative case study was conducted by examining the perceptions of fifth-grade African American girls about their experiences with science, technology, engineering and mathematics (STEM) education and potential for STEM as a future career. As the United States suffers from waning participation across all demographics in STEM and a high level of underrepresentation of African American women in STEM, the proposed study examined data collected through open-ended interviews with fifth-grade African American girls to explore how their current experiences and perceptions might relate to the underrepresentation of African American women in the STEM fields. Participants were selected from Miracle Elementary School (pseudonym), and consisted of all five students in a small class of high-achieving fifth-grade girls. Data were collected through in-class observations and open-ended interviews, and were analyzed using computer content analysis. The most important key results threaded through the data were related to the importance and role of the teacher, the importance of math to students, the role of experimentation and discovery, and hands-on and personal experience. Future studies are encouraged to utilize longitudinal design to follow students from elementary to university level in an effort to develop and understand the perception, persistence, and experience of all girls in STEM programs.

Evaluation of American Indian Science and Engineering Society Intertribal Middle School Science and Math Bowl Project

AISES, None

The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent tomore » the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and Engineering Fair (NAISEF) and EXPO at the Albuquerque, NM Convention Center. Albuquerque is also the home of the AISES national office. The AISES staff also recruits volunteers to assist with implementation of the science and math bowl event. In 2011, there were 7 volunteers; in 2012, 15 volunteers, and in 2013, 19 volunteers. Volunteers are recruited from a variety of local sources, including Sandia Laboratories, Southwest Indian Polytechnic Institute students, Department of Defense, as well as family members of AISES staff. For AISES, the goals of the Intertribal Middle School Science and Math Bowl project are to have more Native students learn science, for them to gain confidence in competing, and to reward their effort in order to motivate them to pursue studies in the sciences and engineering. For DOE, the goals of the project are to get more Native students to compete at the National Science Bowl, held in Washington, DC.« less

This report documents the results of a study which was conducted in order to establish a framework for the quantitative description of the uncertainty in measurements conducted in the National Transonic Facility (NTF). The importance of uncertainty analysis in both experiment planning and reporting results has grown significantly in the past few years. Various methodologies have been proposed and the engineering community appears to be 'converging' on certain accepted practices. The practical application of these methods to the complex wind tunnel testing environment at the NASA Langley Research Center was based upon terminology and methods established in the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME) standards. The report overviews this methodology.

High concentration biotherapeutic formulation and ultrafiltration: Part 1 pressure limits.

PubMed

Lutz, Herb; Arias, Joshua; Zou, Yu

2017-01-01

High therapeutic dosage requirements and the desire for ease of administration drive the trend to subcutaneous administration using delivery systems such as subcutaneous pumps and prefilled syringes. Because of dosage volume limits, prefilled syringe administration requires higher concentration liquid formulations, limited to about 30 cP or roughly 100-300 g L -1 for mAb's. Ultrafiltration (UF) processes are routinely used to formulate biological therapeutics. This article considers pressure constraints on the UF process that may limit its ability to achieve high final product concentrations. A system hardware analysis shows that the ultrafiltration cassette pressure drop is the major factor limiting UF systems. Additional system design recommendations are also provided. The design and performance of a new cassette with a lower feed channel flow resistance is described along with 3D modeling of feed channel pressure drop. The implications of variations in cassette flow channel resistance for scaling up and setting specifications are considered. A recommendation for a maximum pressure specification is provided. A review of viscosity data and theory shows that molecular engineering, temperature, and the use of viscosity modifying excipients including pH adjustment can be used to achieve higher concentrations. The combined use of a low pressure drop cassette with excipients further increased final concentrations by 35%. Guidance is provided on system operation to control hydraulics during final concentration. These recommendations should allow one to design and operate systems to routinely achieve the 30 cP target final viscosity capable of delivery using a pre-filled syringe. © 2016 American Institute of Chemical Engineers Biotechnol.

To validate the Advanced Collapsed cone Engine (ACE) dose calculation engine of Oncentra Brachy (OcB) treatment planning system using an (192)Ir source. Two levels of validation were performed, conformant to the model-based dose calculation algorithm commissioning guidelines of American Association of Physicists in Medicine TG-186 report. Level 1 uses all-water phantoms, and the validation is against TG-43 methodology. Level 2 uses real-patient cases, and the validation is against Monte Carlo (MC) simulations. For each case, the ACE and TG-43 calculations were performed in the OcB treatment planning system. ALGEBRA MC system was used to perform MC simulations. In Level 1, the ray effect depends on both accuracy mode and the number of dwell positions. The volume fraction with dose error ≥2% quickly reduces from 23% (13%) for a single dwell to 3% (2%) for eight dwell positions in the standard (high) accuracy mode. In Level 2, the 10% and higher isodose lines were observed overlapping between ACE (both standard and high-resolution modes) and MC. Major clinical indices (V100, V150, V200, D90, D50, and D2cc) were investigated and validated by MC. For example, among the Level 2 cases, the maximum deviation in V100 of ACE from MC is 2.75% but up to ~10% for TG-43. Similarly, the maximum deviation in D90 is 0.14 Gy between ACE and MC but up to 0.24 Gy for TG-43. ACE demonstrated good agreement with MC in most clinically relevant regions in the cases tested. Departure from MC is significant for specific situations but limited to low-dose (<10% isodose) regions. Copyright © 2015 American Brachytherapy Society. Published by Elsevier Inc.
