Building Bridges An Inclusive Practices Toolkit To Empower Neurodivergent Adults In The Workplace, Gloria Saldana

Student Theses and Dissertations

In this toolkit, designed for managers of neurodivergent employees, we will dig into the complexities of neurodivergence, specifically of Autism Spectrum Disorder (ASD). This toolkit aims to promote inclusivity within the workplace. We need to bridge the gap in improving neurodivergence education by understanding characteristics and communication differences, identifying cues, stigma, and consequences of actions ( e.g., bullying). Prioritizing each person's needs allows neurodivergent individuals and employers to discover natural talents and thrive within a diverse society. Through interactive sessions and practical exercises, managers will learn strategies for clear and concise communication, facilitating smoother collaboration, and initiating changes in the …

Nonalcoholic Fatty Liver Disease (NAFLD) is a prevalent and complex condition influenced by both genetic and environmental factors. This chapter explores the genotype-by-environment interactions that contribute to the development and progression of NAFLD in the Mexican American population. Using advanced genetic epidemiology and bioinformatics approaches, we investigated how specific genetic variants interact with environmental factors such as depression, acculturation stress, and social determinants of health, to influence NAFLD risk and severity. Our findings reveal significant genotype-by-environment interactions for key NAFLD-related traits, including HbA1c, AST/ALT ratio, and steatosis-controlled attenuation parameter (CAP). We also discuss the application of cutting-edge proteomic and transcriptomic …

Examining State Statutory Selection Methods, Term Limits, And Required Qualifications For Appellate Judges As A Model For Reform, Angelo Brown, Wesley Mccann, Ruibin Lu, Brenda I. Rowe, Craig Hemmens

Journal of Criminal Justice and Law

Several reform proposals have been pushed forward for the federal judiciary- namely the United States Supreme Court- in recent years, including term limits, changes in judicial selection, and qualification criteria. Such changes could ostensibly apply to all federal appellate judges as well. The purpose of this study is to determine if states can provide a roadmap for Supreme Court reform discussions. This study utilizes a state-level legal content analysis of all statutes pertaining to judicial selection and qualification criteria for appellate-level judges. Specifically, selection mechanisms, age limits, term limits, and qualifications for selection are examined. Whether state statutory schemes can …

Combining Alaska Forage Fish Data From Research Surveys And Predator Diets To Assess Forage Fish Response To Climatic Regime Shifts, Lindsay Turner Dec 2024

Combining Alaska Forage Fish Data From Research Surveys And Predator Diets To Assess Forage Fish Response To Climatic Regime Shifts, Lindsay Turner

Fisheries

Forage fish play a crucial role in the marine ecosystems of Alaska through the transfer of energy from lower trophic levels to marine predators. Understanding and quantifying Alaskan forage fish responses to rapid climatic shifts is needed to inform adaptive management strategies under a warmer and more variable future in Alaska. However, data on the occurrence and abundance of forage fish in Alaska are limited due to the diversity of life history strategies and patchy distribution that make their capture in fisheries-independent surveys difficult. In this thesis, I address current gaps in the data available on forage fish through the …
