The measurement of retinal blood flow (RBF) in capillaries can provide a powerful biomarker for the early diagnosis and treatment of ocular diseases. However, no single modality can determine capillary flowrates with high precision. Combining erythrocyte-mediated angiography (EMA) with optical coherence tomography angiography (OCTA) has the potential to achieve this goal, as EMA can measure the absolute RBF of retinal microvasculature and OCTA can provide the structural images of capillaries. However, multimodal retinal image registration between these two modalities remains largely unexplored. To fill this gap, we establish MEMO, the first public multimodal EMA and OCTA retinal image dataset. …

The Impact Of Death Anxiety On Counselors’-In-Training Efficacy With Substance Use Populations, Jason Rose May 2024

The Impact Of Death Anxiety On Counselors’-In-Training Efficacy With Substance Use Populations, Jason Rose

Dissertations

Death anxiety has been an unremitting agent of the human experience. The psychological dilemma posed by the awareness and forecasting of death can increase anxiety, thus affecting well-being through the compulsive desire or will to persist (Becker, 1973; Yalom, 1980). Such psychological armor can manifest in conscious and unconscious behaviors, thoughts, and emotions to which persons utilize psychological, social, and cultural defenses to manage anxiety (Becker, 1973; Solomon et al., 2015). Across all levels of counseling, there has been a deficiency in awareness and discussion of death-related fears within the therapeutic process (Lacocque & Loeb, 1988). Therefore, due to the …
