Strategies For Competitive Advantage In Libraries And Information Centers, De-Graft Johnson Dei, Linda Anane-Donkor

Library Philosophy and Practice (e-journal)

Libraries and information centers keep experiencing sluggish growth due to the absence of an integrated and coherent strategy that can be deployed to enable them to be competitive, have a competitive advantage, and gain market position. This study, therefore, sought to assess the strategies for competition in libraries and information centers and develop a framework that can be deployed in libraries and information centers for competitive advantage. The study adopted a conceptual and qualitative approach to research. Based on the review and analysis, the researcher developed a framework that suggests that technology (infrastructure, social media systems, gamification, and artificial intelligence) …

Operating Room First Case On-Time Start Improvement Through Physician Behavioral Modification Aimed At Physician Arrival Times, Ozell E. Diaz

Doctoral Projects

The project aimed to improve first-case on-time starts (FCOTS) for surgical procedures in an acute care hospital by addressing surgeon tardiness, the main contributor to delays. Current policies lacked accountability measures and incentives, leading to routine late arrivals by physicians, with anesthesiology teams also refusing early starts. To address this, the operating room start time was adjusted from 7:30 to 8:00 AM, and physicians were notified of upcoming cases and documentation requirements the evening before surgery. Performance data was shared with surgeons, and those meeting a minimum FCOTS improvement rate were granted priority scheduling. Weekly data reviews, monthly department meetings, …

Using Moss As An Inexpensive Air Pollution Bioindicator For Environmental Equity In Santa Clara Country, California, Tam Dan Tran

Master's Theses

Toxins pervade urban areas and pose long-term health risks to humans. I examine moss as an affordable bioindicator and assess whether moss monitor results reflect other air quality (AQ) indicators, environmental factors, and social vulnerability. Specifically, I investigate (1) whether moss is an effective atmospheric pollution indicator and (2) whether low-income or high-lead-risk neighborhoods experience greater exposure to air pollution. I set out Hypnum cupressiforme moss for two months of exposure in 28 Santa Clara County locations and then measured chromium, zinc, nickel, and the loss of chlorophyll fluorescence in the moss tissue. I gathered real-time particulate matter (PM2.5) measurements …

Mammal Response To Wildfire In Redwood Forests In Northern California, Kristine Doerr

Master's Theses

California has historically experienced recurrent wildfires that have shaped many of the region’s unique ecosystems such as coast redwood (Sequoia sempervirens) forests. Redwood forests, particularly old-growth redwoods, are vital habitats for many wildlife species. Still, these long-living, fire-resistant trees are facing altered fire regimes due to fire suppression and climate change. The 2020 CZU Lightning Complex Fire was a consequence of these changes and significantly altered the landscape of the Santa Cruz Mountain region. This study analyzes mammal recovery after wildfire in high and low fire severity locations of the CZU Fire using two camera trap grids. The high-severity grid …

Exploring Community Adaptation To Public Safety Power Shutoff Events: Findings From Two Case Studies Of Unincorporated Mountain Communities In Southern California, Ramiro M. Brown

Master's Theses

As aging electrical infrastructure in the US continues to succumb to unyielding weather patterns brought on by climate change, there is an urgency among Investor-Owned Utilities (IOUs) to reduce the likelihood of their equipment sparking a wildfire. Public Safety Power Shutoffs (PSPS) – the intentional de-energization of the electrical grid on high fire weather danger days – have become a staple in IOU Wildfire Mitigation Plans (WMPs) since 2018 as one way to avoid wildfire ignitions via electrical infrastructure. One criticism of PSPS events is that they create their own hazard by cutting off power to thousands – sometimes millions-of …

Relationship Between Depression, Rumination, And Emotionally Valenced Working Memory Performance, Dewey Tran

Master's Theses

Working memory is limited in capacity and easily disrupted such that mood states and competing cognitive processes can impair performance. Rumination is highly associated with depression that may contribute to impaired working memory but has not often been studied. The goal of this study was to elucidate the relationship between depression severity, ruminative state, and working memory performance. Participants completed a baseline assessment of depression severity, rumination (trait and state), and working memory then randomly assigned to a rumination or control groups, followed by a second assessment. I hypothesized working memory would be explained by an interaction between depression severity …

Enhancing Cross-Cultural Communication In Low-Resource Language Conversational Agents, Hardi V. Trivedi

Master's Theses

Recent advancements in natural language processing (NLP) and large language models (LLMs) have facilitated the development of systems capable of generating human-like responses across a wide range of tasks. However, the majority of research has focused predominantly on English, overlooking the vast linguistic diversity globally. For true global inclusivity, extending research to other languages is crucial, particularly as it can significantly benefit various sectors such as business, healthcare, government, and education. A major challenge in this expansion is the scarcity of digital data available and the limited number of pre-trained models for low-resource languages. Our research specifically addresses these challenges …

The Effects Of Stress On Attentional Networks, Alice Tsvinev

Master's Theses

The human brain has developed mechanisms to aid our survival, including attentional networks and stress response. Attentional shifts allow humans to react accordingly to their environment, following innate processes like fight or flight. Prolonged exposure to acute stress interferes with such cognitive processes as attention and working memory, impacting attentional systems. The present study examined the effects of acute stress on visual attention processes, specifically focusing on the orienting, alerting, and executive attention networks. 49 participants were randomly placed in either a stress or non-stress condition, then asked to reflect on either stressful or positive moments in their lives, respectively. …

Win-Win Ecology: Can Mosses Promote Dudleya Germination To Restore California Quarries?, Kate L. Worrell

Master's Theses

Human actions directly damage habitat for native plants; restoration ecology facilitates successful plant re-establishment in these environments. Open-pit mines leave behind steep, rocky, and nutrient-deficient habitats that are some of the most degraded ecosystems on the planet. Dudleya or ‘live-forevers’— a genus of native California succulent plants that contains many rare, threatened, or endangered species — grow on rocky cliffs and may create a successful reclamation-restoration story. However, Dudleya germination is poorly understood. Much of the literature on Dudleya cites a single field report suggesting that bryophytes facilitate germination, but no previous experiments have evaluated this proposal. In this study, …

Information About A Racial Demographic Shift May Influence Tolerance For Outgroup Contact, Yvonne N. Phan

Master's Theses

When exposed to information about a demographic shift towards a non-White majority in America, White individuals tend to prefer interactions and settings within their own ethnic group over minority ethnic groups. This behavior may suggest that future inter-racial dynamics in the U.S. could be characterized by resistance from White individuals. To understand how other racial groups respond to information about a racial demographic shift, I collected data on three measures of outgroup tolerance from a multiracial sample of students from San Jose State University’s participant database after exposing them to information about a racial demographic shift driven by a Hispanic …

The Moderating Role Of Meaningful Work On The Relationship Between Loss Of Self-Identity And Psychological Well-Being In Retired Collegiate Athletes, Sarah M. Kurd

Master's Theses

Collegiate athletes are a focal point for many universities. These student-athletes work most of their lives to make it to the university level. Many collegiate athletes aspire to make it to the professional level after they graduate from college, but only a rare handful make it to the top. The rest of the athlete population retires and is placed into a world of “normalcy,” but the transition out of athletics can be very challenging, impacting a person’s psychological well-being. Most of these athletes will have to work a professional job after leaving sports. The present study aimed to examine the …

The Impacts Of Recreational Infrastructure On Mammal Use Of Riparian Zones In Northern California Regional Parks, Emily A. Matthews

Master's Theses

Public lands have been important for the protection of riparian habitats; however, many public lands are also used for recreation, which can reduce mammal habitat use. Understanding how mammals are affected by recreation in riparian areas can help guide management decisions. The goal of this research is to understand the effect of recreation on mammal use of riparian habitats in two popular East Bay Regional Parks, Charles Lee Tilden and Wildcat Canyon, and to map the extent of that impact. Cameras were deployed in the riparian areas of a high, moderate, and low development site (Alvarado, Tilden, and Wildcat Canyon) …

A Trailside Study Of A Coast Redwood Forest Understory Specis, Trillium Ovatum, In The Santa Cruz Mountains, Mary Yan

Master's Theses

To fully understand one of the world’s greatest terrestrial carbon sinks, the coast redwood forest, a co-occurring species may be the key to unique and accessible opportunities to collectively monitor the health of this important habitat. I investigated the relationship between hiking trails and Trillium ovatum within the redwood forests of three California State Parks. Utilizing quadrats across 115 one-meter plots and 58 10-meter transects, T. ovatum occurrence and abundance were recorded and analyzed with factors including proximity to trails, distance from streams, elevation, slope, canopy cover, duff depth, co-occurring understory species, and tree species dominance. Results indicated a higher …

An Assessment Of Anthropogenic Injuries On White Sharks (Carcharodon Carcharias) In Central California, Kaitlyn Yee

Master's Theses

As human activities increasingly impact marine ecosystems, understanding the effects of anthropogenic activity on white sharks is important for their continued conservation. Human-induced injuries are observed in many shark species. Such injuries have been found to have physiological and ecological impacts. Four sites in Central California off the coasts of Aptos, Año Nuevo Island, Southeast Farallon Island, and Point Reyes are all known areas of white shark aggregation with varying levels of human use and protection. Utilizing a vast video database, this study evaluated the effects of natural and non-natural anthropogenic shark injury types across all locations, age classes, and …

Creatine And Depression In Rodents: A Meta-Analysis, Ruchika S. Tirupachur

Master's Theses

Traditional treatments for major depression are based on the monoamine deficiency hypothesis, and they fail to achieve remission in a substantial portion of patients. Newer evidence suggests the pathophysiology of depression is a more complex story, highlighting a need for research in alternative therapies. Mounting evidence shows a linkage between depression and the supplement creatine monohydrate (CRMH). Research in rodent models suggests that CRMH may both alleviate depressive symptoms and enhance the efficacy of standard antidepressants like SSRIs. The following study describes findings from a combined fixed- and random-effects meta-analysis based on four empirical studies investigating the effect of CRMH …

It’S Complicated: The Level Of Risk Assigned To A Missing Person, Time They Were Missing For, And The Tasks Performed By Police Investigators., Karen Shalev, Craig Collie

International Journal of Missing Persons

This study examines the number of tasks police investigators perform by the level of risk assigned to cases and the length of time the investigations take to resolve. It analyses 40,091 solved cases from 2019 using data from eight English police forces, as part of a wider research project of missing person investigations demand on police resources. The findings show that (1) low and high risk with a search area cases have a relationship to the duration of the investigation; (2) there is a relationship between the risk classification and the number of tasks assigned to the case; (3) the …

An Exploration Into Why There Is An Overrepresentation Of Bame People In Missing Person Cases, Phoebe Sleigh-Johnson, Fiona Gabbert Dr., Adrian J. Scott

International Journal of Missing Persons

The overrepresentation of Black, Asian, and Minority Ethnic (BAME) people in missing person cases is an issue that is not understood within society and has largely been neglected within academic literature to date. This study, therefore, aims to explore why this overrepresentation might exist by obtaining the views and opinions of 24 professionals (including police officers) working within the field of missing people. The study used a qualitative, exploratory method and an anonymous online survey containing a series of open-ended questions. Thematic analysis was performed on the data, and three main themes were identified; the first related to the idea …

Supporting & Protecting Repeat Missing Children From Different Residential Environments: A Scoping Review, Kirsty Bennett Dr, Petra Salisbury, Rebecca O'Keefe, Sharon Vincent, Bethany Mccarthy

International Journal of Missing Persons

Repeat missing children pose a significant financial burden onto services, including the police, social services, and health providers. Recognising that 37 to 65 percent of missing child reports each year are repeats, efforts have been made by academics and practitioners to understand this societal problem. Research has identified the risks causing children to go missing and the harms that they experience, but these focus primarily on children missing from residential care only. This PRISMA (2020) scoping review of 76 studies explores strategies implemented to prevent repeat missing episodes, and the role/influence of the home environment (e.g., with parents/guardians, and foster …

Racial Bias In Risk Allocation And Resource Utilisation: A Contributing Factor To Ethnic Minority Overrepresentation In Missing Person Investigations?, Amy Van Langeraad, Fiona Gabbert, Adrian J. Scott

International Journal of Missing Persons

Statistics from the National Crime Agency reveal that people from ethnic minority backgrounds are over-represented within the missing population in the United Kingdom, and previous archival studies have shown there is a discrepancy in the recovery of ethnic minority missing persons compared to White missing persons. A wider body of research shows that racial bias is prevalent in the criminal justice system and law enforcement, resulting in different outcomes for victims depending on their racial background. Such outcomes have yet to be examined in the context of missing persons. Therefore, this study tries to address this gap in the literature …

Gait Measurement Descriptions Of Human Tracks, Robert Speiden

International Journal of Missing Persons

Search and rescue missions use a variety of tools to find missing persons, one of which can be visual tracking. Trackers detect, interpret and document information about human contact with the ground. Humans typically move on two feet at various speeds. Movement as an obligate biped leaves a series of footprints that alternates from one side to the other. This pattern of footfalls is rather simple, and the footfalls can be easily divided into descriptive dimensions.

This work summarized published measurements of bipedal gait ground contact points in 70 resources. Four resource types were surveyed including 33 biomechanical gait analysis …

Adversarial Attacks And Defenses In Multivariate Time-Series Forecasting For Smart And Connected Infrastructures, Pooja Krishan, Rohan Mohapatra, Sanchari Das, Saptarshi Sengupta

Faculty Research, Scholarly, and Creative Activity

The emergence of deep learning models has revolutionized various industries over the last decade, leading to a surge in connected devices and infrastructures. However, these models can be tricked into making incorrect predictions with high confidence, leading to disastrous failures and security concerns. To this end, we explore the impact of adversarial attacks on multivariate time-series forecasting and investigate methods to counter them. Specifically, we employ untargeted white-box attacks, namely the Fast Gradient Sign Method (FGSM) and the Basic Iterative Method (BIM), to poison the inputs to the training process, effectively misleading the model. We also illustrate the subtle modifications …
