Sustaining Voice Through Leadership: How Do Deaf Leaders Sustain Voice in Challenging Dominant Systems

The vehicle in communicating cultural identity, recognition, and justice is voice. Reclaiming or sustaining one\u27s voice is to stand up for what one believes in, or to preserve one\u27s identity and place in society. The deaf individual or any other marginalized individual is expected to proceed through a series of deliberations to determine favorable actions that will be persuasive, with the goal of embracing the voice of the marginalized. The deaf individual\u27s voice or meaningful intentions will need to be effectively interpreted into mainstream American society\u27s language and paradigms. This requires one to reconstruct the meanings and mediate the facts and historical stories through his/her cultural lens into a language that mainstream American society is accustomed to hearing and experiencing. This is a daunting challenge and a burden for those who do not mediate multiple cultures and languages effectively. The methodology for this research will be descriptive phenomenology. This phenomenological research will focus on lived experience and elicit rich, deep descriptions. The focus of these lived experiences will be uncovered through dialogues with deaf leaders. The aim is to uncover deeper meanings surrounding the leadership relationship between the deaf leader and the dominant system. Themes will be identified and descriptions will capture the essence of the interviews. The focal question for the phenomenological research is: How do deaf leaders sustain voice in challenging dominant culture/systems? The sub-questions are: 1) Are there specific leadership qualities that are unique among deaf leaders leading in challenging dominant culture/system? 2) Are deaf leaders challenged with traditional leadership in relation to their cultural lens, myopic views, or systemic thinking of the dominant culture/system to their own cultural lens? 3) How do deaf leaders position themselves to sustain voice and effect change? The document concludes with implications for leadership and change. An electronic version of this dissertation is at OhioLink ETD Center www.ohiolink.edu/et

AN INVESTIGATION OF AI CAMERA CAPABILITIES FOR UNMANNED SURFACE VESSEL OPERATIONS

Includes Supplementary MaterialUnmanned surface vessels (USVs) typically rely on Global Positioning System (GPS) and radio frequency (RF) communications for navigation and multi-vehicle coordination. In a wartime environment, GPS and radio signal blockers present challenges for effective USV navigation and control. This thesis investigates the use of low-cost artificial intelligence (AI)–enabled stereo cameras as a sensor for enabling GPS and RF-free navigation and coordination for USVs. These cameras can also be used to classify and localize surface vessels. Experiments were performed with OAK-D AI cameras mounted on multiple Mokai USVs. A neural network (NN) model was trained to identify two object classes: a Mokai USV and other vessels. Using open-source Python libraries, this model was loaded directly onto the camera and integrated into Robot Operating System (ROS) software to extract relative pose information of detected objects. The NN was tested on unseen video and during live field experiments using the Mokai USVs and other surface vessels to analyze the model’s effectiveness. Camera-estimated object localization was compared to objects’ ground truth locations collected through physical verification in a lab setting. Lastly, the limitations of the specific camera hardware and stereo vision for this application were explored to assess their feasibility for further development.Distribution Statement A.

A systematic evaluation of paediatric medicines information content in clinical decision support tools on smartphones and mobile devices

Background Medication information is often poorly delineated for paediatric patients, resulting in high off-label and non-licensed use of drugs in this population. Access to accurate medicines information in this population becomes a necessity in order to avoid medication errors. Clinical decision support tools (CDSTs), which are increasingly available on mobile devices (e.g. smartphones), can provide healthcare providers with convenient access to paediatric medicines information at point of care. However, to date no systematic evaluation of the content in these CDSTs has been conducted. Objectives To evaluate paediatricmedicines information in CDSTs for smartphones and other mobile devices. Method Evaluation of CDSTs according to scope and completeness was accomplished via weighted categories of 108 questions distributed evenly across three age groups: infants, children and adolescents. Results Three paediatric-specific databases and six general databases were evaluated. The best performer provided 75.9% of the answers for scope and scored 69.7% for completeness. Databases generally performed less effectively in providing answers sourced from clinical guidelines compared with more conservative sources such as package inserts. Conclusions Overall, general medicines information CDSTs performed better than paediatricspecific CDSTs in both scope and completeness. Results from this study may help guide CDST selection on mobile devices by healthcare professionalswhose patient populations include paediatrics

Interest rate variance swaps: pricing mechanics under stochastic volatility, market expectations, and historical perspectives

Treball fi de màster de: Master's Degree in Economics and Finance. Financial Economics Program . Curs 2024-2025Tutora: Eulàlia NualartThis paper investigates the pricing and risk management of U.S. Treasury Interest Rate Variance Swaps (IRVS) from 2015 to 2024. We construct synthetic variance swaps using three strike-setting methods: market-implied (MOVE Index), model-based (Heston), and historical average realized variances. Our analysis reveals horizon-dependent break-even points, approximately 95, 126, and 42 trading days, respectively, highlighting the critical role of time horizon in valuation. These results show that model choice and horizon selection significantly impact IRVS payoffs, helping investors interpret market sentiment and align yield volatility expectations. Our findings provide actionable guidance for portfolio strategies and policymaking.Aquest article investiga la fixació de preus i la gestió de riscos dels swaps de variància dels tipus d’interès dels Bons del Tresor dels EUA (IRVS) del 2015 al 2024. Construïm swaps sintètics amb tres mètodes de colpeig: variància implícita (índex MOVE), model Heston i variàncies històriques realitzades mitjana. L’anàlisi revela punts d’equilibri segons l’horitzó (95, 126 i 42 dies), subratllant la seva importància en la valoració. Els resultats mostren que el model i l’horitzó impacten els pagaments IRVS, ajudant els inversors a interpretar el sentiment de mercat i les expectatives de volatilitat dels rendiments. Això ofereix orientacions útils per a estratègies de cartera i polítiques
