Senecio Conrathii N.E.Br. (Asteraceae), A New Hyperaccumulator Of Nickel From Serpentinite Outcrops Of The Barberton Greenstone Belt, South Africa, Stefan Siebert, Nadine Carol Schutte, Stoffel Pieter Bester, Dennis Mmakgabo Komape, Nishanta Rajakaruna

Biological Sciences

Five nickel hyperaccumulators belonging to the Asteraceae are known from ultramafic outcrops in South Africa. Phytoremediation applications of the known hyperaccumulators in the Asteraceae, such as the indigenous Berkheya coddii Roessler, are well reported and necessitate further exploration to find additional species with such traits. This study targeted the most frequently occurring species of the Asteraceae on eight randomly selected serpentinite outcrops of the Barberton Greenstone Belt. Twenty species were sampled, including 12 that were tested for nickel accumulation for the first time. Although the majority of the species were excluders, the known hyperaccumulators Berkheya nivea N.E.Br. and B. zeyheri …

Establishment Of Occupational Safety And Health As A Minor, Giovani A. Mazzotti

Construction Management

Safety plays an essential role in the construction industry. With construction projects increasing in size, time, and overall complexity, it has become increasingly difficult to implement safe protocol and procedures. Present-day construction projects sometimes require more than 10,000 employees, including dozens of subcontractors, office teams, and more on-site. In addition to the increased need for laborers, increasing project size means an increase in demand for individuals with expertise and experience in safety practices. Projects of all shapes and sizes are in need of professionals with proven expertise in implementing safety practices. Currently, many incoming project engineers and field engineers lack …

Improving Swarm Performance By Applying Machine Learning To A New Dynamic Survey, John Taylor Jackson

Master's Theses

A company, Unanimous AI, has created a software platform that allows individuals to come together as a group or a human swarm to make decisions. These human swarms amplify the decision-making capabilities of both the individuals and the group. One way Unanimous AI increases the swarm’s collective decision-making capabilities is by limiting the swarm to more informed individuals on the given topic. The previous way Unanimous AI selected users to enter the swarm was improved upon by a new methodology that is detailed in this study. This new methodology implements a new type of survey that collects data that is …

Knee Angles And Axes Crosstalk Correction In Gait, Cycling, And Elliptical Training Exercises, Jordan M. Skaro

Master's Theses

When conducting motion analysis using 3-dimensional motion capture technology, errors in marker placement on the knee results in a widely observed phenomenon known as “crosstalk” [1-18] in calculated knee joint angles (i.e., flexion-extension (FE), adduction-abduction (AA), internal-external rotation (IE)). Principal Component Analysis (PCA) has recently been proposed as a post hoc method to reduce crosstalk errors and operates by minimizing the correlation between the knee angles [1, 2]. However, recent studies that have used PCA have neither considered exercises, such as cycling (C) and elliptical training (E), other than gait (G) nor estimated the corrected knee axes following PCA correction. …

Reproduction As A Crime: State Intervention During Pregnancy, Emily Spacek

Paideia

This paper briefly examines the actions by states that criminalize substance use during pregnancy through a critical lens that grants attention to the reasons for and implications of punishing pregnant women for specific actions taken during pregnancy. It first embarks on a case study into a particular Alabama law that has warranted the arrests of hundreds of women since its implementation in 2006. Then, using qualitative research, this paper investigates broader state intervention into the lives of pregnant, substance using women via criminal prosecution and the termination of parental rights. Results indicate that current punitive policies have often developed without …

Influence Of Internal Bores On Larval Fish Abundance And Community Composition, Patrick J. Phelan, John Steinbeck, Ryan K. Walter

Physics

A persistent semidiurnal internal tidal bore feature occurs at the head of the Monterey Bay Submarine Canyon and drives regular intrusions of cold, subthermocline waters onto the adjacent shelf. In this study, we examine the influence of this internal tidal bore feature on the larval fish community using over a year of periodic larval fish samples collected coincidently with physical measurements. Larval samples were categorized into one of two water mass periods: a “warm period” representative of shallow coastal shelf waters and a “cold period” characteristics of colder waters present during internal bore forcing. Using multivariate statistical methods, we show …

Evaluating Recruitment Seasonality Of Red Abalone (Haliotis Rufescens) To Inform Fisheries Management And Conservation Policy, Leslie Hart

Baker/Koob Endowments Awarded Projects

Understanding the seasonality of red abalone recruitment (larval settlement) and the relationship between recruitment and oceanographic conditions is critical for managing this economically important species. Red abalone, Haliotis rufescens, were historically part of a recreational and commercial fishery in southern and central California until overharvesting and disease rapidly decreased populations. Recruitment dynamics of red abalone are poorly understood. Previous research conducted at a central California site, Hopkins Marine Life Refuge (HMLR), from 2012-2015 reveal remarkably consistent recruitment rates of red abalone, while northern California recruitment greatly fluctuated within the same time period. To address this gap in our knowledge, I …

Lessons On Evolution From The Study Of Edaphic Specialization, Nishanta Rajakaruna

Biological Sciences

Plants adapted to special soil types are ideal for investigating evolutionary processes, including maintenance of intraspecific variation, adaptation, reproductive isolation, ecotypic differentiation, and the tempo and mode of speciation. Common garden and reciprocal transplant approaches show that both local adaptation and phenotypic plasticity contribute to edaphic (soil-related) specialization. Edaphic specialists evolve rapidly and repeatedly in some lineages, offering opportunities to investigate parallel evolution, a process less commonly documented in plants than in animals. Adaptations to soil features are often under the control of major genes and they frequently have direct or indirect effects on genes that contribute to reproductive isolation. …

Cal Poly Liberal Studies Program: A Look At The Growing Focus On Stem In Teacher Preparation, Erin Goode

Cal Poly's History: Student Research Reports

Teacher preparation at Cal Poly has had a presence on campus since the 1950’s. Under the title of Liberal Studies, the program has developed into one of the foremost teacher preparation programs in the state. Part of Liberal Studies’ success is from a growing focus on STEM education for teachers both through the curriculum and outside programs. This paper discusses the benefits of the Liberal Studies Department residing under the College of Science and Mathematics and the increased opportunities the program were exposed to after moving from the College of Liberal Arts in 2009.

Converting Agricultural Lesson Plans To Be Common Core Compliant For Grades 3-5, Hattie Kaymarie Jameson, Brittany Rose Withnell

Agricultural Education and Communication

There are few Common Core approved lesson plans for teachers to incorporate into traditional science programs in California. The Farm Bureau’s Ag in the Classroom (AITC) program provides K-12 educators lesson plans with an agricultural focus. Only 13 out of 45 of the lesson plans that the California AITC website offers are Common Core approved (Learn About Ag, 2017).

Agricultural literacy is valuable to consumers, can lead to careers in agriculture, and can create a greater understanding of the world and of science for students. The agricultural lessons give students a real life relationship with what they are learning and …

Biophilia: Alienation And Solidarity, Ralph Acampora

Between the Species

Biophilia, theorized by Fromm, Wilson, and Kellert, is examined as a potential support for a pro-animal ethos. First, I look at the idea and its definitions at the hands of its chief theorizers. Then I investigate how different stages of human cultural development (foraging, pastoralism, industrial agriculture) have influenced different aspects of biophilia—especially as this bears on animal alienation. Finally, I consider possible remedies in the form of renewed patterns of solidarity with other species, one of which transforms Marx’ concept of species-being. The article has ethical implications, but it is essentially a work in philosophical anthropology.

An Empirical Study Of Css Code Smells In Web Frameworks, Tobias Paul Bleisch

Master's Theses

Cascading Style Sheets (CSS) has become essential to front-end web development for the specification of style. But despite its simple syntax and the theoretical advantages attained through the separation of style from content and behavior, CSS authoring today is regarded as a complex task. As a result, developers are increasingly turning to CSS preprocessor languages and web frameworks to aid in development. However, previous studies show that even highly popular websites which are known to be developed with web frameworks contain CSS code smells such as duplicated rules and hard-coded values. Such code smells have the potential to cause adverse …

The Impacts Of Sex And Myogenic Cell Transplantation On Collateral Capillary Arteriogenesis, Padon Mary Sivesind

Master's Theses

Current treatments for peripheral arterial occlusive disease (PAOD) have limited success, so there is a need to develop more effective treatments. Because patients with native collaterals have a better prognosis, promoting collateral arteriogenesis is a potential PAOD treatment. Additionally, female PAOD patients have a worse response to treatment and a worse prognosis compared to males, which could be due to impaired collateralization. Cell transplantation is a potential treatment option to promote collateral arteriogenesis. Bone marrow derived stem cells are the main cell type that has been investigated, but they have had limited clinical success. Delivering a stem cell type native …

Powder Bed Surface Quality And Particle Size Distribution For Metal Additive Manufacturing And Comparison With Discrete Element Model, Irene Yee

Master's Theses

Metal additive manufacturing (AM) can produce complex parts that were once considered impossible or too costly to fabricate using conventional machining techniques, making AM machines an exceptional tool for rapid prototyping, one-off parts, and labor-intensive geometries. Due to the growing popularity of this technology, especially in the defense and medical industries, more researchers are looking into the physics and mechanics behind the AM process. Many factors and parameters contribute to the overall quality of a part, one of them being the powder bed itself. So far, little investigation has been dedicated to the behavior of the powder in the powder …

Enhancements To The Microbial Source Tracking Process Through The Utilization Of Clustering And K-Nearest Clusters Algorithm, Tram B. Lai

Master's Theses

Bacterial contamination in water sources is a serious health risk and the sources of the bacterial strains must be identified to keep people safe. This project is the result of a collaboration effort at Cal Poly to develop a new library-dependent Microbial Source Tracking method for determining sources of fecal contamination in the environment. The library used in this study is called Cal Poly Library of Pyroprints (CPLOP). The process of building CPLOP requires students to collect fecal samples from a multitude of sources in the San Luis Obispo area. A novel method developed by the biologists at Cal Poly …
