A Generative Approach To Understanding Categorical Visual Search, Seoyoung Ahn, Hossein Adeli, Gregory Zelinsky

MODVIS Workshop

Search theory relies heavily on the concept of a template, an internal representation of the target that, via a matching process to a visual input, creates a top-down signal biasing attention to a target. The search template was originally conceptualized as being specific to a given object, but over the years this definition broadened to include the features of a target category. Exploiting recent generative methods, we suggest re-conceptualizing the search template yet again, thinking of it now as a fully-generated target object residing in peripheral vision and not just a collection of features. Our approach is to generate potential …

Feature Integration And Spatial Localization For Attention Across The Visual Hierarchy, Joyce Tam, Chloe Callahan-Flintoft, Brad Wyble

MODVIS Workshop

The featural and spatial specificity of visual representations broadly decrease along the ventral visual stream. The selection of behaviorally relevant information, or attention, must therefore establish spatial correspondence across the visual hierarchy while maintaining behavioral guidance to relevant visual features. Moreover, selection is often accompanied by an inhibitory surround as well as selective inhibition of distractor items. Considering these key functions, we describe a biologically realistic computational theory of visual selection and inhibition through feedforward and feedback signals along the ventral visual stream, complemented by feature-agnostic spatial competition in the pulvinar nuclei. Our model simulates signature visual search behaviors and …

Evaluating Ccr Unit Closure Options – Closure In Place Or Closure By Removal, Rick Buffalini

World of Coal Ash Proceedings

Evaluating Surface Impoundments Closure by Removal and Closure in Place Options Authors Mr. Rick Buffalini - United States - Civil & Environmental Consultants, Inc. Abstract The USEPA interpretation of the 2015 CCR Regulations is that closure in place requires that the CCR not be in contact with groundwater, that post-closure infiltration of groundwater from the subsurface be eliminated, and that free liquids be eliminated from the CCR. As a result, owners of surface impoundments that had previously intended to close in place are now evaluating other options to dewater the CCR or closure by removal. This presentation will address evaluations …

Water Management And Construction Impacts, Christine Harris

World of Coal Ash Proceedings

Water Management and Construction Impacts Authors Mrs. Christine Harris - United States - Groundwater Treatment and Technology, LLC (GWTT) Abstract When closing an ash impoundment there are many steps in the process. Understanding the relationship between water management and civil construction is important. In most cases, before civil construction can begin, free liquids must be removed from the impoundment. Usually, the water removed must be treated before it can be discharged. The success (or failure) of these two activities can have an impact on the ability of the civil construction contractor to perform the work. The responsibility for dewatering is …

Museums have stuck to traditional rules of focusing interpretation only on the object, having a single exceptional curator, and top-down dissemination of information. One California museum has created a different cultural exhibit that rejects all of these pillars to create an active museum. New Museum Los Gatos (NUMU Los Gatos) recently held an exhibition titled: Reclamation: Resilience of the Muwekma Ohlone Tribe. Collaborating with the Muwekma Ohlone, aboriginal to the San Francisco Bay Region, this exhibit spotlights and provides a platform for the Muwekma to the surrounding Los Gatos community who may not be aware of the local indigenous …

From Classroom To College: The Impact Of Educators Of Color On Long-Term Commitment Of Students Of Color, Haley Hayes

Education | Master's Theses

Research has shown that educators of color are essential for students of color to feel a sense of belonging and acceptance in their early developmental stages of education. According to Morgan (2019), “the findings of a recent study supported the idea that assigning teachers of color the same race leads to an increase in positive subjective assessments with regard to behavior and skills” (p.158). Prior research has considered issues that prevent people of color from becoming educators and/or remaining in the field, while also considering the environment and tools needed for educators of color to be successful in their jobs. …

Teacher Voices: Stress And Coping Mechanisms Among The Teaching Profession, Jasmine Suttles

Education | Master's Theses

Stress is a natural response that occurs in our body when we feel overwhelmed, and it can manifest in both positive and negative instances. The teaching profession is not exempt from this phenomenon, as it is unique in that educators have multiple roles to play and have to manage and interact with many students simultaneously. Teachers have been described as "exasperated by heavy loads of emotional labor in the classroom" (Ferguson et al., 2022). This "heavy load" can place the teaching profession at risk of stress and burnout if self-care is not addressed or mental health resources are not offered. …
