The Effect Of Alternative Work Regimes On Recruiter Productivity, Keith Sean Cogdell

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines the impact of different work regimes, onsite, remote, and hybrid, on recruiter productivity within the staffing industry. As workforce models evolve, organizations encounter challenges in determining how these structural changes influence employee performance. Existing studies are often cross-sectional and rely heavily on self-reported data, limiting their capacity to capture long-term trends and contextual factors. To address this issue, the present research utilizes a longitudinal design with five years of recruiter-level performance data from a national staffing firm, which includes over 27,000 observations. Using Self-Determination Theory (SDT) as a framework, the study investigates how intrinsic motivation mediated by …

Quarantine measures limited doctor’s appointments and isolated pregnant women from their families, which meant that meaningful connections and convenient information was important.

The purpose of this study is to explore the implications of COVID-19 social distancing on pregnant women, with a focus on three questions: 1) what digital technologies did pregnant women use for support and information seeking purposes during the pandemic? 2) how did pregnant women use technology to seek social support during the pandemic? 3) how did …

The Influence Of The Covid-19 Pandemic On Student Engagement At A Historically Black University, John C. Travis

Theses and Dissertations

This study examined student engagement across three NSSE administrations at an HBCU—pre-COVID (2018), during COVID (2019), and post-COVID (2022). Engagement was analyzed across four themes: Academic Challenge, Learning with Peers, Experiences with Faculty, and Campus Environment. Results showed that Learning with Peers declined significantly over time, with the largest drop between 2018 and 2022, reflecting pandemic-related disruptions to peer interaction. No significant year effects emerged for the other themes. Two-way MANOVAs indicated that gender, first-generation status, and major did not significantly predict engagement, nor did they interact with year.

Cause Of Death? -- It's Probably Not What's Reported On The Death Certificate, Lauren R. Roth

Lewis & Clark Law Review

In the age of big data, this country has a data problem—inaccurate and incomplete information in death certificates. The problem has long been hidden by the numbers reported—as have the people whose deaths go uncounted, but the COVID-19 pandemic unveiled the scope of the issue. Since the beginning of the pandemic, “excess deaths” (i.e., any deaths above the number predicted by existing mortality models) have increased significantly. Most of these excess deaths are likely attributable to COVID-19 because the decedent was never tested for COVID-19 or it was one of multiple factors contributing to their death. Other deaths are uncounted …

Kafka In The Plague Years: Reinterpreting Absurdity In The 2020s, Chris Lownie

Electronic Theses & Dissertations (2024 - present)

No word better encapsulates the confusion and inequality proliferating in the post-2020 global world than “absurd.” Absurdity consumes the way we interact with one another, going about life-as-usual in pocket worlds in which the individual is alienated from both oneself and others. Life is defined by a series of problems that regularly go ignored by both institution and general populace alike, but not by the human body: the effects of sustained illness and reinfection by recurrent viruses in a world that no longer acknowledges their severity nor their pervasiveness nor steps we may take towards personal safety. Daily life has …

Association Of Non-Communicable Diseases With Severe Covid-19 Among People Living With And Without Diagnosed Hiv/Aids In New York State, Ravi Kumar Balu

Electronic Theses & Dissertations (2024 - present)

Background: People living with diagnosed HIV (PLWDH) have a higher chance of co-infections and co-morbidities than the general population. When SARS-CoV-2 was first reported in China in December 2019 and later declared a pandemic, it was speculated that PLWDH might be more prone to SARS-CoV-2 infection and severe disease outcomes given their increased vulnerability to other respiratory infections like influenza, pneumococcal pneumonia and tuberculosis. However, several facets of COVID-19 disease in PLWDH are incompletely understood, including whether non-communicable diseases (NCDs) are strong risk factors for severe disease outcomes and death as they are in the general population.

Methods: The data …

Should The X-Minute City Include Commutes? An Evaluation Using Commute And Well-Being Data From The Singapore Life Panel®, Sock Yong Phang, Yen Cong Wong, Stephen Hoskins

Research Collection School Of Economics

Over the past decade, the x-minute city — or “chrono-urbanism” — has gained traction intransport planning, emphasizing residents’ ability to access essential destinations within15-min travel time from their homes. Some cities, including Sydney and Singapore, haveextended this concept to commuting, with Singapore’s Land Transport Authority targetinga “45-min city” for daily commutes by 2040. While well-intentioned, applying time-basedgoals to commuting remains controversial. This study evaluates the validity of thex-minute commute city as a transport planning objective by examining the link betweencommuting duration and well-being. Using high-frequency panel data from 2,535Singapore residents aged 55 to 75, we analyze how commuting affects life …

The Impact Of Coping Strategies On The Perceived Stress And Well-Being Of People With Disabilities During The Covid-19 Pandemic, Angela G. Maccarrone

Clinical Psychology Dissertations

The COVID-19 pandemic significantly and negatively impacted those around the world, particularly marginalized groups such as people with disabilities (PWDs). What remains unclear from existing published research is the exact relationship between perceived stress of the pandemic, coping, and overall well-being in PWDs. Prior research and theoretical models of coping suggest that active coping processes are associated with more positive outcomes versus avoidant coping strategies, which have shown less favorable outcomes on well-being. Due to the varying ways in which the pandemic affected PWDs, coping might serve as a moderator, amplifying the negative relationship between perceived stress and well-being. Building …

Teacher Attrition During And After A Pandemic: A District’S ‘New Normal’ View, Tammy H. Jacobs

The Development Of A One Pot, Two Reaction Synthetic Preparation Of 1,2,4-Oxadiazole, And Synthesis Of Ataluren, A Novel Drug In The Fight Against Duchenne Muscular Dystrophy. Efforts Towards The Synthesis Of A Potential Protease Inhibitor Against The Main Protease (3clpro) Of Covid-19, Austin J. Carter

Theses and Dissertations

1,2,4-Oxadiazoles are five-membered heterocyclic structures first synthesized by Tiemann and Krüger in 1884. Recent discoveries suggest an array of useful biological properties.In preparation of 1,2,4-oxadiazoles, the most prevalent precursors are amidoximes, which can be created via the reaction of nitriles with hydroxylamine hydrochloride and a base. The amidoximes are reacted with an activated carboxylic acid to yield an acylated intermediate. This intermediate can be exposed to a base to cyclize into the 1,2,4-oxadiazole. This thesis describes the efforts in combining these three steps into a unified one-pot synthesis.

Currently, there are a significant number of commercially available FDA approved and …

Children's Interpretation Of Others' Faces Covered With Medical Masks, Sevval Cinar

Theses and Dissertations (Comprehensive)

How we recognize and regulate emotions is fundamental to overall health and wellbeing. Emotional recognition and understanding are key to proper communication and emotion regulation. Barriers, such as masks, might have an impact on the way children recognize and interpret others' emotions, and therefore the way they learn, communicate, and regulate their own. The COVID-19 pandemic necessitated widespread mask-wearing, raising questions about its impact on children’s emotional development. Using a sample of children with varying levels of exposure to mask wearing adults (N= 13, ages 4 to 6), we investigated how prolonged mask wearing predicts emotion recognition, particularly …
