Individual Differences In Verbal And Visuospatial Learning Efficiency, Thomas Spaventa

Arts & Sciences Graduate Student Theses and Dissertations

There is a great deal of variability in how quickly people learn and how long they remember information. Zerr and colleagues (2018) found a robust and stable relationship between an individual’s rate of learning and the durability of their memory, with faster learners tending to retain more after a delay. The relationship between the rapidity and longevity of learning was characterized as learning efficiency. The present study extends these findings by testing whether learning efficiency generalizes across divergent verbal and visuospatial tasks. An ancillary aim was to assess learning efficiency using a continuous measure that can capture fine-grained individual differences …

Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck

Arts & Sciences Graduate Student Theses and Dissertations

Across the lifespan, personality changes in normative ways, but the source of such change remains ambiguous. Life events may be one impetus of such change, but strong selection effects into such events makes it unclear whether such change is driven by already existing differences (selection) between people or socialization following life events. In a preregistered study, we test socialization and selection effects of the Big 5 and life events using a large (N = 19,627) representative sample of Germans and 12 life events (e.g. marriage, retirement) from the GSOEP. Using propensity score matching and Bayesian multilevel growth curve models, we …

Female Acrobatics In Context: 5th-4th C. Bc, Marleigh Anderson

Arts & Sciences Graduate Student Theses and Dissertations

The ‘meaning’ of a performance is largely determined by its context. This idea became clear to me after years as a dancer performing in drastically different venues—including nursing home lobbies, circus tents, makeshift outdoor festival stages, football fields, and ornate theatres. To me, every performance opportunity felt distinct, especially depending on the audience and the nature of the performance. This is the personal background that I bring to my study of female acrobatic performances in ancient Greek society, and it is part of the reason that I find it critical to consider these performances within their contexts. Even if the …

Learning From Past Conflict: Investigating The Time Scale Of Conflict Learning For Cognitive Control Processes, Abhishek Dey

Arts & Sciences Graduate Student Theses and Dissertations

Conflict-modulated cognitive control accounts posit that control processes adjust attention based on the probability of conflict associated with a given context (e.g., list of items, a particular item within a list, etc.). However, within these accounts, it is not yet fully understood how the control system learns about the probability of conflict. A specific question I address in the present research is how far back does the control system look to learn about the probability of conflict? In other words, what is the time scale of conflict learning for the control system? I use a statistical model recently developed by …

Examining Emotional Pain Among Individuals With Chronic Physical Pain: Nomothetic And Idiographic Approaches, Madelyn Frumkin

Arts & Sciences Graduate Student Theses and Dissertations

Pain is often conceptualized as an experience that is both physical and emotional. These two components are often difficult to distinguish, which may contribute to the experience of chronic physical pain without an apparent physical cause. In the current two studies, I sought to examine whether emotional pain is associated with physical pain severity for individuals with chronic pain. Emotional pain and the more specific experiences of psychological and social pain have been defined as the experience of pain affect in response to non-physical stimuli (i.e., thwarted belongingness, loss, social rejection). In Study 1, I found that emotional and psychological …

Development And Validation Of New Models And Metrics For The Assessments Of Noise-Induced Hearing Loss, Wisam Subhi Talib Al-Dayyeni

Dissertations

Noise-induced hearing loss (NIHL) is one of the most common illnesses that is frequently reported in the occupational and military sectors. Hearing loss due to high noise exposure is a major health problem with economic consequences. Industrial and military noise exposures often contain high-level impulsive noise components. The presence of these impulsive noise components complicates the assessment of noise levels for hearing conservation purposes. The current noise guidelines use equal energy hypothesis (EEH) based metrics to evaluate the risk of hearing loss. A number of studies show that the current noise metrics often underestimates the risk of hearing loss in …

Opportunities To Advance Complex Care In Rural And Frontier Areas, Jim Lloyd

Project ECHO Bibliography

People with complex care needs who live in rural communities face many of the same challenges experienced by individuals in urban areas, such as lack of transportation and food insecurity. However, rural communities are not just scaled-down cities. Despite facing similar challenges to patients living in urban areas, individuals with complex needs in rural areas often face additional hurdles caused by lack of infrastructure and geographic distances, making many high-touch complex care interventions difficult — if not impossible — to implement.

This brief, made possible through the Robert Wood Johnson Foundation, explores challenges associated with providing complex care in rural …

Direct Detection Of Relic Neutrino Background Remains Impossible: A Review Of More Recent Arguments, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

The existence of big bang relic neutrinos—exact analogues of the big bang relic photons comprising the cosmic microwave background radiation—is a basic prediction of standard cosmology. The standard big bang theory predicts the existence of 1087 neutrinos per flavour in the visible universe. This is an enormous abundance unrivalled by any other known form of matter, falling second only to the cosmic microwave background (CMB) photon. Yet, unlike the CMB photon which boasts its first (serendipitous) detection in the 1960s and which has since been observed and its properties measured to a high degree of accuracy in a series of …

Isolate To A Controllable Space, Simone Frances

MFA Thesis Exhibit Catalogs

Centered around the public arena of institutional architecture and its impact on the social being, in this recent work, entitled, Isolate to a Controllable Space, I focus on questions such as how do public environments work to sustain and reiterate meaning through our own sense of where we should be, or where we are permitted to be. I use photography to approach questions that ask how do systems and infrastructures obtain functionality through our participation; acknowledging that systems are conductors of the personal and participatory process of identification and categorization.
