An Empirical Examination Of The Impact Of Organizational Injustice And Negative Affect On Attitude And Non-Compliance With Information Security Policy, Celestine Kemah

CCE Theses and Dissertations

Employees’ non-compliance with Information Security (IS) policies is an important socio-organizational issue that represents a serious threat to the effective management of information security programs in organizations. Prior studies have demonstrated that information security policy (ISP) violation in the workplace is a common significant problem in organizations. Some of these studies have earmarked the importance of this problem by drawing upon cognitive processes to explain compliance with information security policies, while others have focused solely on factors related to non-compliance behavior, one of which is affect. Despite the findings from these studies, there is a dearth of extant literature that …

Pause For A Cybersecurity Cause: Assessing The Influence Of A Waiting Period On User Habituation In Mitigation Of Phishing Attacks, Amy Antonucci

CCE Theses and Dissertations

Social engineering costs organizations billions of dollars a year. Social engineering exploits the weakest link of information security systems, the people who are using them. Phishing is a form of social engineering in which the perpetrator depends on the victim’s instinctual thinking towards an email designed to create a fear or excitement response. It is well-documented in literature that users continue to click on phishing emails costing them and their employers significant monetary resources and data loss. Training does not appear to mitigate the effects of phishing much; other solutions are necessary to mitigate phishing.

Investigating The User Experience With A 3d Virtual Anatomy Application, Winnyanne Kunkle

CCE Theses and Dissertations

Decreasing hours dedicated to teaching anatomy courses and declining use of human cadavers have spurred the need for innovative solutions in teaching anatomy in medical schools. Advancements in virtual reality (VR), 3D visualizations, computer graphics, and medical graphic images have enabled the development of highly interactive 3D virtual applications. Over recent years, variations of interactive systems on computer-mediated environments have been used as supplementary resource for learners. However, despite the growing sophistication of these resources for learning anatomy, studies show that students predominantly prefer traditional methods of learning and hands-on cadaver-based learning over computer-mediated platforms.

Using Dialogue To Contextualize Culture, Ecosystem Services, And Cultural Ecosystem Services, Karen Allen, Celia Castellano, Sophia Pessagno

Open Access Fund Publications

We propose an alternative methodology for engaging with multifaceted cultural ecosystem services (CES) in the Global South. We explore the use of dialogue as a tool for understanding CES in situ, while developing shared action steps toward CES conservation among stakeholders. We held six dialogue workshops in the rural Central Pacific region of Costa Rica that were designed to foster understanding of shared community values for ecosystem services and associated conservation challenges. In two of the workshops, we employed model-based reasoning through which we used maps as boundary negotiating objects to nurture dialogue on CES values, observations, and concerns. In …

Awareness Of Climate Change’S Impacts And Motivation To Adapt Are Not Enough To Drive Action: A Look Of Puerto Rican Farmers After Hurricane Maria, Luis Alexis Rodríguez-Cruz, Meredith T. Niles

College of Agriculture and Life Sciences Faculty Publications

Understanding how perceptions around motivation, capacity, and climate change’s impacts relate to the adoption of adaptation practices in light of experiences with extreme weather events is important in assessing farmers’ adaptive capacity. However, very little of this work has occurred in islands, which may have different vulnerabilities and capacities for adaptation. Data of surveyed farmers throughout Puerto Rico after Hurricane Maria (n = 405, 87% response rate) were used in a structural equation model to explore the extent to which their adoption of agricultural practices and management strategies was driven by perceptions of motivation, vulnerability, and capacity as a function …

Analysis Of Uncertainty In Hydrometeorological Ensemble Forecasts, Carolien N. Mossel

Dissertations and Theses

Ensemble hydrometeorological forecasting has great potential for improving flood predictions and use in water management systems, however, the amount of data used and created with an ensemble forecast requires a careful and intentional approach to understand how useful and skillful the forecast is. The NOAA National Water Model (NWM) was run using downscaled NOAA Global Ensemble Forecast System (GEFS) meteorological forcings for the 2016-2017 wet season (October-March) in California to create an 11-member hydrologic forecast ensemble. To evaluate the performance of these ensemble forecasts, we chose to study streamflow sites within Sonoma County, California, a rain-dominated region which includes the …

Comparison Of Calculated Normal Mode Molecular Vibrations With Experimental Gas-Phase Infrared Spectroscopy, Anila Renis Sutar

Dissertations and Theses

Computational vibrational spectroscopy serves as an important tool in the interpretation of experimental infrared (IR) spectra. Analysis of computational results provides a perspective over broader wavelength ranges and at higher precision. Although there are issues regarding accuracy, this can be approximated by using a scaling factor. High-resolution gas-phase FTIR spectroscopy at a resolution of 0.125 cm^-1 can partially resolve rovibrational transitions in the P, Q, and R bands and therefore identify fundamental frequencies with approximately 1 cm^-1 precision.

This research has compared high-resolution gas-phase FTIR absorption peaks to calculated vibrational frequencies. In the calculation of normal mode frequencies, …

The spatial clumping of …

Surface Acoustic Waves Increase Magnetic Domain Wall Velocity, Anil Adhikari, Shireen Adenwalla

Shireen Adenwalla Papers

Domain walls in magnetic thin films are being explored for memory applications and the speed at which they move has acquired increasing importance. Magnetic fields and currents have been shown to drive domain walls with speeds exceeding 500 m/s. We investigate another approach to increase domain wall velocities, using high frequency surface acoustic waves to create standing strain waves in a 3 micron wide strip of magnetic film with perpendicular anisotropy. Our measurements, at a resonant frequency of 248.8 MHz, indicate that domain wall velocities increase substantially, even at relatively low applied voltages. Our findings suggest that the strain wave …

On The Acceptance Of Urban Beavers In Martinez, California, Zane A. Eddy

Cal Poly Humboldt theses and projects

As ecosystem engineers, beavers construct complex riparian and wetland habitats that benefit many other species, including endangered salmonids. Through their landscape alterations, beavers also promote increased groundwater recharge and provide refugia during wildfires and high flow events by impounding water and allowing it to spread across the landscape. Prior to the North American colonial fur trapping campaigns, there were between 60 and 400 million beavers in North America. By the beginning of the 20th century, beavers were extirpated from many parts of the continent, however through human efforts, their population has since rebounded to between 10 and 15 million. The …

Populations Of Major Phases In Glacier Peak Lavas, Charlotte Wall

Geology Graduate and Undergraduate Student Scholarship

Volcanoes can be studied through minerals that are present in their eruption products. These minerals can be studied through optical microscopy and geochemistry to better understand their origins and provide insight into which processes took place prior to eruption (i.e., fractionation of crystals, assimilation of the surrounding crust, magma mixing). In this study I examine mineral populations in dacite (lava of intermediate composition) from Dahkobed/Glacier Peak volcano in the north Cascade Arc. The samples consist of a felsic (high SiO2) host component and a mafic (low SiO2) inclusion component. To establish base mineral populations, minerals from both the host and …

Rwanda To Phase Out Polluting Vehicles By 2040, An Efficient Strategy To Mitigate Global Warming Effects?, Josue Kwizera

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Passenger vehicles are major pollutants because on average a typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. I highly support the idea that Rwanda joined on November 11, 2021, a group of countries at the COP26 UN climate talks that have made an agreement to end polluting vehicles by 2040. Rwanda is a landlocked country with a 12.95 million population as of 2020(world bank). Rwanda currently has over 221,000 registered vehicles; 83980 are passenger vehicles, 114,900 vehicles (52 percent of those vehicles) are motorcycles and the rest include public transports (buses and minibuses) and trucks …

30 By 30, Laron Core

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Biden’s 30 by 30 plan, a regulatory approach to conservation, an imminent response to environmental action, a promise of inclusivity to all stakeholders. Or a broken promise in the making, an environmental policy inadequate to deliver sufficient results to its stakeholders? I am set to believe Biden’s 30 by 30 plan could very well be DOA.

Simiode Expo 2021 - Minicourse M-R2 - Delay Differential Equations In Epidemiology, Nsoki Mavinga

Mathematics & Statistics Faculty Works

Many problems in epidemiology give rise to delay differential equations (DDEs). These are differential equations in which the current rate of change of the system depends not only on the current state but also on the history of the system; i.e. the system has memory. In this minicourse, we will discuss some key tools necessary to understand the applications involving DDEs. We will go through an example that illustrates the need and implementation of DDE in certain infectious diseases.
