31	End-of-life decision-making among African Americans with serious illness Smith-Howell, Esther Renee 07 May 2015 (has links) Indiana University-Purdue University Indianapolis (IUPUI) / African Americans' tendency to choose life-prolonging treatments (LPT) over comfort focused care (CFC) at end-of-life is well documented but poorly understood. There is minimal knowledge about African American (AA) perceptions of decisions to continue or discontinue LPT. The purpose of this study was to examine AA family members' perceptions of factors that influenced end-of-life care decision-making for a relative who recently died from serious illness. A conceptual framework informed by the literature and the Ottawa Decision Support Framework was developed to guide this study. A retrospective, mixed methods design combined quantitative and qualitative descriptive approaches. Forty-nine bereaved AA family members of AA decedents with serious illness who died between 2 to 6 months prior to enrollment participated in a one-time telephone interview. Outcomes examined include end-of-life treatment decision, decision regret, and decisional conflict. Quantitative data were analyzed using descriptive statistics, independent-sample t-tests, Mann-Whitney U tests, chi-square tests, Spearman and Pearson correlations, and linear and logistic regressions. Qualitative data were analyzed using content analysis and qualitative descriptive methods. Family members' decisional conflict scores were negatively correlated with their quality of general communication (rs = -.503, p = .000) and end-of-life communication scores (rs = -.414, p = .003). There was a significant difference in decisional regret scores between family members of decedents who received CFC versus those who received LPT (p = .030). Family members' quality of general communication (p = .030) and end-of-life communication (p = .014) were significant predictors of family members' decisional conflict scores. Qualitative themes related to AA family members' experiences in end-of-life decision-making included understanding (e.g., feeling prepared or unprepared for death), relationships with healthcare providers (e.g., being shown care, distrust) and the quality of communication (e.g., being informed, openness, and inadequate information). Additional qualitative themes were related to perceptions of the decision to continue LPT (e.g., a lack of understanding, believe will benefit) or discontinue LPT (e.g., patient preferences, desire to prevent suffering). In conclusion, this study generated new knowledge of the factors that influenced AA bereaved family members' end-of-life decision-making for decedents with serious illnesses. Directions for future research were identified. African American Communication Decision-making End-of-Life Care Family Members Palliative Care Bereavement -- African Americans
32	Reconnaissance Radar Robot Holm, Kasper, Henrysson, Erik January 2023 (has links) During the last century, various countries' armed forces have used unmanned aerial vehicles, commonly known as drones. In recent years, strives have been made to develop small commercial drones that have allowed the general public to afford and use them for recreational purposes. The availability of drones has led to immoral applications of the technology. Such applications need to be faced with anti-measures and effective detection methods. Therefore, this thesis aims to develop a mobile reconnaissance robot that can detect commercial drones with radar. It describes integrating radar sensors with single-board computers to detect and localise air-bound objects. The finished product aims to be used for educational and exhibition purposes at the Swedish Armed Forces technical school to increase awareness of the technology. / <p>Försvarsmaktens tekniska skola i Halmstad var intressenter för uppsatsen.</p> radar signal processing signal processing state machine state machine test testing radar testing radar technology frequency modulated continuous wave fmcw pulse radar raspberry pi single board computer sbc poe power over ethernet mqtt mqtt package python drones uav unmanned aerial vehicle drone detection radar robot swedish armed forces swedish armed forces technical school fmts beamforming fast fourier transform fft point cloud point clustering software design Computer and Information Sciences Data- och informationsvetenskap Computer Sciences Datavetenskap (datalogi) Software Engineering Programvaruteknik Signal Processing Signalbehandling Computer Systems Datorsystem
