Implicit Bias And The Boundaries Of Belief: A Single-Representational Dual-Attitude Account Of Implicit Attitudes, Austin Dakota Synoground

Graduate Theses and Dissertations

Since their inception, implicit attitudes have been defined as associative mental states, separate from beliefs, which are considered to be propositional in nature. Recently, several philosophers have challenged this distinction, arguing that implicit attitudes are actually unconscious beliefs. In turn, I argue that the attitudes detected by current experimental paradigms are blind to distinctions between implicit attitudes, which I define as the products of an associative learning mechanism, and unconscious beliefs, which are the products of a propositional learning mechanism. Specifically, I argue for a single-representational dual-attitude account of implicit bias.

Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell

Graduate Theses and Dissertations

Purpose: The purpose of these studies was to determine if arterial angulations (through sitting or standing), shear stress (through local heating), or a combination of these factors affected vascular function. Moreover, this studied estimated the magnitude of the effect that biological sex has on these vascular responses. Methods: Twenty-six healthy, young (18-40 years old) males (n=13) and females (n=13) completed two experimental trials (2-h sitting and 2-h standing). In a randomized fashion, one leg was passively heated in order to increase shear rate. Following a 48-h washout, participants returned to the laboratory to complete the other trial.

Therefore, the purpose of the present study was to examine individual frontal alpha electroencephalographic asymmetry index (FAI) score in eu-hydrated, hypo-hydrated, and exercise in well-trained men and assess if there is a correlation between FAI score and individual ad libitum fluid consumption behavior. Subjects were kinesiology major college students ranging from 21 to 29 years of age. Subjects were categorized either approach group (n = 8) with resting FAI score more than 0 or avoidance …

The Good, The Bad, And The Ugly Behavior, Michal Lavi

Cardozo Law Review

Shaming is usually referred to as the publication of perceived anti-social or illegal behavior of an individual in order to condemn or humiliate him. It has some virtues: it makes it harder for people to get away with wrongful behavior, and it promotes justice. It also promotes freedom of expression and enables efficient deterrence. By spreading information on the behavior of individuals, shaming encourages one to maintain his reputation and facilitates beneficial transactions. Finally, it helps the public to avoid inefficient services.

Yet shaming raises many problems. Anyone can shame another based on individual, as opposed to universal, values, thus …

Research outputs 2014 to 2021

In this study, we report the beneficial effects of a newly identified dermal cell subpopulation expressing the ATP‐binding cassette subfamily B member 5 (ABCB5) for the therapy of nonhealing wounds. Local administration of dermal ABCB5⁺‐derived mesenchymal stem cells (MSCs) attenuated macrophage‐dominated inflammation and thereby accelerated healing of full‐thickness excisional wounds in the iron‐overload mouse model mimicking the nonhealing state of human venous leg ulcers. The observed beneficial effects were due to interleukin‐1 receptor antagonist (IL‐1RA) secreted by ABCB5⁺‐derived MSCs, which dampened inflammation and shifted the prevalence of unrestrained proinflammatory M1 macrophages toward repair promoting anti‐inflammatory M2 …

Computed Tomography Imaging Findings Of Acute Aortic Pathologies, Elif S. Duran, Farhan Ahmad, Mohamed Elshikh, Irfan Masood, Cihan Duran

School of Medicine Publications

Acute aortic syndromes (AAS) encompass a spectrum of life-threatening conditions characterized by acute aortic pain. AAS include acute aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, and aneurysm rupture. The prognosis of AAS is clearly related to prompt diagnosis and appropriate management. The different types of AAS cannot be reliably differentiated solely based on clinical presentation since the clinical features are indistinguishable. Multidetector-row computed tomography (MDCT) with electrocardiographic gating (ECG-gated MDCT) has been used in the acute emergency setting as a powerful clinical tool, which enables rapid and specific diagnosis of aortic pathologies. ECG-gated MDCT significantly reduces motion artifact and avoids …
