Generational Information Security Awareness And The Role Of Big Five Personality Traits, Gloria Mccue

Walden Dissertations and Doctoral Studies

AbstractTechnological change drives organizations to safeguard information systems. However, such safeguards are dependent upon people to follow security rules. This study examined generational cohorts and personality traits and their impact on information security awareness. Participants in this study were 137 volunteers who completed an anonymous survey online. Two tools were utilized to collect data from the participants: the Human Aspects of Information Security Questionnaire and the Big Five Inventory, which captured behaviors and personality traits, respectively. The three main generational cohorts represented in the study, Baby Boomers, Generation X, and Generation Y, were in today’s workforce. The results of the …

Public Participation In Georgia’S Environmental Permitting Process, Joyce A. Stanley Jan 2023

Public Participation In Georgia’S Environmental Permitting Process, Joyce A. Stanley

Walden Dissertations and Doctoral Studies

There is no meaningful way for Georgia residents to participate in the environmental decision-making process before environmental permits are approved. As a result, hazardous waste facilities are disproportionately placed in African American communities, exposing them to poor air quality and a higher prevalence of heart and respiratory diseases than Whites. The purpose of this qualitative case study was to explore and better understand how African American residents living in Stonecrest, Georgia felt about the hazardous waste site being placed in their community without an opportunity to provide input into the Georgia Environmental Protection Division’s (GEPD) decision-making process before a decision …

Analysis Of Fiber Uv Degradation Through An Environmental Chamber, Davis A. Eames Jan 2023

Analysis Of Fiber Uv Degradation Through An Environmental Chamber, Davis A. Eames

UROP Posters

Environmentally degraded fibers could impact multiple aspects of a fiber comparison, considering that collected weathered fabrics/fibers may express an altered chemical structure and/or colorimetric property compared to their unexposed counterparts. Depending on the amount of degradation the evidence has suffered, it could be challenging for forensic scientists to make conclusions from their comparative analyses. Observations presented in this study were orchestrated to test the possible outcomes that sunlight has on fabric-based materials. Photodegradation of fabrics was investigated through the use of an environmental chamber for a duration of six weeks, which would be equivalent to three months of real-world UV …

Hashes Are Not Suitable To Verify Fixity Of The Public Archived Web, Mohamed Aturban, Martin Klein, Herbert Van De Sompel, Sawood Alam, Michael L. Nelson, Michele C. Weigle Jan 2023

Hashes Are Not Suitable To Verify Fixity Of The Public Archived Web, Mohamed Aturban, Martin Klein, Herbert Van De Sompel, Sawood Alam, Michael L. Nelson, Michele C. Weigle

Computer Science Faculty Publications

Web archives, such as the Internet Archive, preserve the web and allow access to prior states of web pages. We implicitly trust their versions of archived pages, but as their role moves from preserving curios of the past to facilitating present day adjudication, we are concerned with verifying the fixity of archived web pages, or mementos, to ensure they have always remained unaltered. A widely used technique in digital preservation to verify the fixity of an archived resource is to periodically compute a cryptographic hash value on a resource and then compare it with a previous hash value. If the …

Applied Environmental Research

Phosphorus (P) is an essential nutrient for phytoplankton growth in water bodies and an important element in biochemical processes. Also, excessive P in river causes eutrophication which endangers aquatic organisms while sediment acts as sink for inorganic and organic pollutants and nutrients. To assess the availability of P and heavy metals (HMs) in Ogun River, surface sediment samples were collected at twelve anthropogenic sites for three months. The surface sediment samples were sequentially extracted to determine five phosphorus fractions [loosely-sorbed P (LS-P), iron-bound P (Fe-P), authigenic apatite, biogenic apatite and CaCO3-bound P (CFA-P), detrital apatite (Det-P) and other inorganic P …

Applied Environmental Research

This study aimed to determine the diclofenac removal in wastewater by sludge taken from an operating wastewater treatment facility. Laboratory experiments were conducted in two parts: batch and moving-bed biofilm reactor (MBBR) experiments. Results from batch experiments showed that 0.1–2 mg L-1 of diclofenac could be removed more than 80% within 72 h, and the removal efficiency reduced to less than 60% for higher concentrations. The increase in the removal rate from 0.00058 to 0.16527 mg L-1 h-1 was observed when the initial diclofenac concentration increased from 0.1 to 10 mg L-1, respectively. The average first-order rate constants of 24-h …
