From Ordinary To Extraordinary: A Framework Of Experience Types, Mat D. Duerden, Neil R. Lundberg, Peter Ward, Stacy T. Taniguchi, Brian Hill, Mark A. Widmer, Ramon Zabriskie

Faculty Publications

Understanding the nature of, and how to design, structured experiences has become an increasingly salient topic for academics and professionals over the past two decades. Despite the rise in interest in experiences, the related academic literature is fragmented and often atheoretical. To address this situation, this article presents a framework of experiences—including construct definitions and propositions— to help guide the research and design experiences. The framework considers the realm of all possible experiences from subconscious to conscious and subdivides conscious experiences into ordinary and extraordinary dimensions. The framework further classifies extraordinary experiences as memorable, meaningful, and transformational. The distinction between …

A Reference Framework For Conceptual Modeling, Lois M. L. Delcambre, Stephen W. Liddle, Oscar Pastor, Veda C. Storey

Faculty Publications

With decades of contributions and applications, conceptual modeling is very well-recognized in information systems engineering. However, the importance and relevance of conceptual modeling is less well understood in other disciplines. This paper, through an analysis of existing research and expert opinions, proposes a reference framework for conceptual modeling to help researchers and practitioners position their work in the field, facilitate discussion among researchers in the field, and help researchers and practitioners in other fields understand what the field of conceptual modeling has to offer as well as contribute to its continued, extended influence in multiple domains.

Deployable Lenticular Stiffeners For Origami-Inspired Mechanisms, Larry L. Howell, Alden D. Yellowstone

Faculty Publications

Light-weight origami-inspired mechanisms can provide advantages in deployable space systems and other applications. However, a significant challenge in their design is ensuring that they are sufficiently stiff. Compliant, deployable stiffeners utilizing a profile approximating the Euler Spiral are proposed as one solution. Structures with this profile, called a lenticular stiffener, are shown to permit stiffeners to flatten using forces applied at their edges. Formulas for calculating the stiffness increase are developed. Relations needed to design the deployment behavior of the stiffeners are also derived. Finally, advantages of different stiffener configurations are evaluated. These results are verified through simulation and experiments.

Religion, Language, Gender, And Culture: Challenges Experienced By Saudi International Students In Humboldt County, Dafer Sahab Alqarni

Cal Poly Humboldt theses and projects

The effects of culture shock on individuals living abroad are well known. Less well known, however, are the specific experiences, needs, and challenges of Saudi Arabian students studying internationally, especially in Western nations. In this study, I used qualitative research to explore the needs and difficulties of Saudi international students in Humboldt County and at Humboldt State University (HSU). Using semi-structured interviews with eight participants, diversified by gender and marital status, I provide a holistic view of HSU Saudi international students’ experiences and challenges which could help to understand Saudi students’ experiences abroad generally, and in Humboldt County specifically.

Productivity And Cost Of A Cut-To-Length Commercial Thinning Operation In A Northern California Redwood Forest, Kigwang Baek

Cal Poly Humboldt theses and projects

Cut-to-length (CTL) harvesting systems have recently been introduced to the redwood forests of California’s north coast. These machines are being used to commercially thin dense redwood (Sequoia sempervirens) stands which tend to form clumps of stems that vigorously sprout from stumps after a harvest. One of the challenges is to avoid damaging residual trees which can decrease productivity, increase costs, and lower the market value of trees. The goal of this study was to evaluate the productivity and costs associated with CTL systems used in a redwood forests and use that data to develop equations for predictions. Time …

Technical Feasibility And Life Cycle Cost Assessment Of A Photovoltaic Array On Trinity Dam, Trinity County, Ca, Caleb Aaron Patrick

Cal Poly Humboldt theses and projects

Public lands owned by the Bureau of Land Management are increasingly being used for photovoltaic (PV) system development. Although numerous policies support PV deployment on public lands, those managed by the Bureau of Reclamation have not been considered for PV development. Hydro-electric embankment dams, both publicly and privately owned, may have the potential to be development sites for distributed PV systems. A technical feasibility report was conducted for a case study of a PV installation on Trinity Dam, Trinity County, CA, and found embankment dams could potentially be feasible development sites. A mounting analysis found that a concrete slab reinforced …

Effect Of Different Alumina Supports On Performance Of Cobalt Fischer-Tropsch Catalysts, Thomas H. Fletcher

Faculty Publications

Four identically-prepared 20 wt% cobalt/0.15 wt% ruthenium Fischer-Tropsch catalysts, supported on different aluminas, were synthesized by incipient wetness impregnation, characterized, and compared based on their performance under standard Fischer-Tropsch synthesis conditions. Three alumina supports were obtained from commercial sources (Sasol, St. Gobain, and Alfa Aesar), while the fourth was made using a published technique that included 5 wt% silica. The silica-stabilized alumina catalyst produced superior Fischer-Tropsch rates of 49 mmol CO/gcat h, compared to the other catalysts on the commercial supports with rates of 26–39 mmol CO/gcat h. The improved performance of the silica-stabilized alumina support compared to the commercially …

Sex-Specific Habitat Selection Of Rough-Legged Hawks (Buteo Lagopus) Wintering In Western North America, Genevieve Christa Rozhon

Cal Poly Humboldt theses and projects

The rough-legged hawk (Buteo lagopus sanctijohannis) is one of the most under-studied raptor species in North America. As a species that exhibits reversed sexual dimorphism, sex-specific habitat preferences may exist. To investigate rough-legged hawk sex-specific habitat selection preferences, we equipped 17 rough-legged hawks (n = eight females, nine males) with GPS backpacks on their wintering grounds (n = six study areas) during the winter months of 2014 and 2015 in five states in western North America. I analyzed rough-legged hawk habitat selection in relation to sex at four spatial scales: nocturnal roosting site, 50% core range, 95% winter …

Stability For A Small Historic House Museum: Drafting A Collection Management Policy For The Trinidad Museum, Alexandra Mackay Cox

Cal Poly Humboldt theses and projects

A museum exists and is defined primarily by its collection. It is therefore important for a museum to manage its collection effectively while preserving it for long-term use. The size and scope of the museum's collection will determine the complexity of its policy. As such, all museums, including small ones, need a well-defined Collection Management Policy (CMP). This policy outlines what and how to collect, defines the development and use of the collection as well as procedures for the care of the collection, the loaning of items and removing of items from the museum's collection. The Trinidad Museum, a small …

Yet, this system fails to address the needs of a diverse population that struggles with a disproportionate degree of poor health outcomes. In order to understand the unique challenges facing the region’s food system – and how local government and advocacy groups should begin to address healthy food policy - this research thesis analyzes key texts about food, which illustrate the language and ideologies of eating local in Humboldt County. This research thesis found that the concept of eating local – consuming foodstuffs …

Evaluating Socioeconomic Dimensions For A Resilient Shellfish Mariculture Industry In Humboldt Bay: Assessing The Strengths, Vulnerabilities, And Potential Of Humboldt’S Expanding Industry, Wyatt G. Smith

Cal Poly Humboldt theses and projects

For nearly 90 years the shellfish mariculture industry in Humboldt Bay has coexisted with various stakeholder groups and the Bay’s delicate ecology. Presently, the shellfish mariculture industry in Humboldt Bay is composed of six shellfish producing businesses ranging in operational size from small-scale to large-scale. Commercial shellfish production from Humboldt Bay yields over 70 percent of California’s mature, market-sized, Pacific oysters (Crassostrea gigas) and Kumamoto oysters (C. sikamea). Shellfish growers in the Bay also produce seed from Pacific oysters, Kumamoto oysters, and Manila clams (Tapes semidecussata).

As the mariculture industry in Humboldt Bay is …

Dynamic Balance Of Experienced And Novice Rock Climbers, Brian G. Shea

Cal Poly Humboldt theses and projects

Climbing requires heavy use of the upper body muscles in the torso and arms to pull the body vertically or traverse horizontally. The upper body profile of climbers has been characterized, however there is little research that has examined the lower body and its contribution to climbing performance. There are studies that have examined postural control while climbing, but no study has evaluated the dynamic balance of the lower extremities in climbers. For this study, lower body dynamic balance was measured using normalized reach distances of the Star Excursion Balance Test (SEBT). Eighteen adult, indoor climbers (n=12) and non-climbers (n=6) …

Framings Of Nature In Planet Earth Ii And Wild Safari Live, Joshua Gross

Cal Poly Humboldt theses and projects

The percentage of the world’s population living in cities continues to grow, while media technologies become ever more ubiquitous. As a result, the mass media’s role in connecting the general public to the natural world will only increase; the wildlife genre of television may have a particularly large role to play in this regard. Unfortunately, previous authors have argued that the over-dramatized depictions of nature in mainstream wildlife programs may serve to disconnect viewers from the natural world. Scholarship has also not kept up with recent developments in wildlife television, with few authors writing about hugely successful programs like Planet …

The Effect Of The Loss Of Lgl1 In Murine Neural Progenitor Cells On Mapk Signaling And Proliferation, Monique R. Lacourse

Cal Poly Humboldt theses and projects

Glioblastoma is an incurable, aggressive, and highly invasive type of brain tumor that harbors tumor initiating cells characterized by disrupted polarized cell divisions. A cell polarity gene lethal (2) giant larvae 1 (Lgl1) has been implicated in gliomas and is a tumor suppressor initially identified in Drosophila with roles in proliferation. The loss of Lgl1 in Drosophila activates the MAPK protein kinase JNK and the Ras pathway and therefore its downstream kinase ERK, a transcription factor modulator. Furthermore, when Lgl1 is knocked out in mice, a phenotype similar to glioma is seen. Loss of the human form of …

Comparing L1 And L2 Texts And Writers In First-Year Composition, Grant Eckstein, Dana Ferris

Faculty Publications

Scholars have at various points discussed the needs of second language (L2) writers enrolled in “mainstream” composition courses where they are mixed with native (L1) English speakers. Other researchers have investigated the experiences of L2 writers in mainstream classes and the perceptions of their instructors about their abilities and needs. Little research, however, has directly compared L1 and L2 students (mostly Generation 1.5) taking composition classes together. For this article, the researchers collected writing samples from 56 L1 and 74 L2 students enrolled in a university (mainstream) first-year composition course. Using a mixed-methods design, they analyzed the texts for language …

Controlling Normal Stiffness In Droplet-Based Linear Bearings, Qi Ni, Nathan B. Crane

Faculty Publications

While Capillary forces are negligible relative to gravity at the macroscale, they provide adequate force to effectively manipulate millimeter to micro meter objects. The fluidic actuation can be accomplished using droplets that also act as bearings. While rotary droplet bearings have been previously demonstrated, this paper considers the performance potential of discrete droplets acting as linear bearings. Specifically, it addresses the positioning accuracy of a droplet-based bearing consisting of a droplet between a moving plate and a stationary substrate with constrained wetting region under a normal load using both closed form analytical solutions and numerical simulations. The vertical force and …

Impact Of Vapor Polishing On Surface Quality And Mechanical Properties Of Extruded Abs, Clayton Neff, Matthew Trapuzzano, Nathan B. Crane

Faculty Publications

Purpose — Additive manufacturing (AM) is readily capable of producing models and prototypes of complex geometry and is advancing in creating functional parts. However, AM processes typically underperform traditional manufacturing methods in mechanical properties, surface roughness, and hermeticity. Solvent vapor treatments (vapor polishing) are commonly used to improve surface quality in thermoplastic parts, but the results are poorly characterized.

Design/methodology/approach — This work quantifies the surface roughness change and also evaluates the effect on hermeticity and mechanical property impacts for “as-printed” and acetone vapor-polished ABS tensile specimens of 1, 2, and 4 mm thicknesses produced by material extrusion (FDM).

A Comparison Of Traditional And Adaptive Comparative Judgment Assessment Techniques For Freshmen Engineering Design Projects, Scott R. Bartholomew, Greg J. Strimel, Andrew Jackson

Faculty Publications

This article examines the use of an alternative form of assessment for engineering design projects called adaptive comparative judgment (ACJ). The researchers employed an ACJ tool to evaluate undergraduate engineering student design projects in an effort to examine its’ reliability, validity, and utility in comparison with traditional assessment techniques. The ACJ process employed multiple judges to compare the design artifacts of 16 first-year engineering majors. The authors conducted an analysis of the reliability and validity of the ACJ method compared to the traditional rubric used to evaluate the project and the performance data of each student’s design prototype. For these …

An Origami-Based Thickness-Accommodating Bistable Mechanism In Monolithic Thick-Sheet Materials, Larry L. Howell, Spencer P. Magleby, Nathan A. Pehrson

Faculty Publications

Origami-based mechanisms can provide useful capabilities in folding large structures to stow in small volumes. However, when using monolithic thick-sheet materials for these types of mechanisms, accommodating the thickness proves challenging. One approach to solve this is to create compliant mechanisms along the fold lines that inherently store energy when actuated and causes the mechanism to tend toward its low energy state. This tendency can be used to create bistable states. We outline a method to use this stored energy to achieve bistable states and name the resulting mechanism an origami-based “Thickness-accommodating bistable interior vertex” (TABIV) in monolithic thick-sheet materials. …

Bytecode-Based Multiple Condition Coverage: An Initial Investigation, Srujana Bollina

Theses and Dissertations

Masking occurs when one condition prevents another condition from influencing the output of a Boolean expression. Logic-based adequacy criteria such as Multiple Condition Coverage (MCC) are designed to overcome masking at the within-expression level, but can offer no guarantees about masking in subsequent expressions. As a result, a Boolean expression written as a single complex statement will yield test cases that are more likely to overcome masking than when the expression is written as series of simple statements. Many approaches to automated analysis and test case generation for Java systems operate not on the source code representation of code, but …

Association Between Mechanics And Biology In Vascular Graft Remodeling, David Andrew Prim

Theses and Dissertations

Coronary artery bypass grafting (CABG) restores myocardial perfusion in patients with severe coronary artery disease by utilizing autografts – usually at least one of the internal thoracic artery (ITA), radial artery (RA), and great saphenous vein (GSV) – to bypass stenosed regions of coronary arteries. While decades of research and clinical improvements have made CABG an indispensable procedure, tens of thousands of grafts fail each year, which is due, at least in part, to an inability of the source vessels to adapt to the altered stimuli of the coronary circulation. In this dissertation, we first quantify and compare the mechanical …

Ecological Role Of Burrowing Sea Cucumbers, Holothuria Arenicola, In Abaco, Bahamas, Liberty Boyd

Harriet L Wilkes Honors College Theses 2010 - 2019

Bioturbators serve as ecosystem engineers, influencing community dynamics of the environments in which they are endemic. Currently, the bioturbator, Holothuria arenicola, a species of burrowing sea cucumbers, is listed as data deficient by the IUCN. These animals may affect the structure and function of seagrass beds, which are critical habitats for various species. To assess the ecological role of H. arenicola , I conducted field surveys, calculated mound, and analyzed mound nutrient levels. I gathered data through monitoring study plots, conducting Bran-Blanquette seagrass surveys (Fourqurean et al., 2001), capturing GoPro video, and collecting samples. Results indicate an insignificant difference between …

Is Video The Most Effective Marketing Type?, David Casto

Harriet L Wilkes Honors College Theses 2010 - 2019

In this thesis, I ask the question of whether or not video is the most effective marketing type. I answer this question by evaluating companies in the business, scientific, and health arenas and discuss why and how they have used video to market themselves. Further, I also examine the ways in which technology has grown in the past few decades, and discuss the different types of learning and how video can appeal to each type. With the results of this research, I ultimately conclude that video is the most effective marketing type. as the actually commodity being provided. I defend …

Pollution Sensitivity Of Macrolichens On Southern Live Oak (Quercus Virginiana), Christy Folk

Harriet L Wilkes Honors College Theses 2010 - 2019

Lichens in south Florida are poorly documented. I surveyed macrolichens on the bark of Southern live oak trees (Quercus virginiana) present on the John D. MacArthur campus of Florida Atlantic University in Jupiter, Florida, to establish a baseline and to determine how automobile pollution may impact lichen species diversity and density. Ten randomly-selected trees in each of two study areas (adjacent to Parkside Drive versus mid-campus, away from any road) were surveyed for lichen species diversity and coverage. Fifteen species of lichens were identified using identification keys and chemical spot tests. Lichen diversity was similar in the two areas of …
