Description
No studies have evaluated the impact of tracking resting energy expenditure (REE) and modifiable health behaviors on gestational weight gain (GWG). In this controlled trial, pregnant women aged >18 years (X=29.8±4.9 years) with a gestational age (GA) <17 weeks were randomized to Breezing™ (N=16) or control (N=12) for 13 weeks.

No studies have evaluated the impact of tracking resting energy expenditure (REE) and modifiable health behaviors on gestational weight gain (GWG). In this controlled trial, pregnant women aged >18 years (X=29.8±4.9 years) with a gestational age (GA) <17 weeks were randomized to Breezing™ (N=16) or control (N=12) for 13 weeks. The Breezing™ group used a real-time metabolism tracker to obtain REE. Anthropometrics, diet, and sleep data were collected every 2 weeks. Rate of GWG was calculated as weight gain divided by total duration. Early (GA weeks 14-21), late (GA weeks 21-28), and overall (GA week 14-28) changes in macronutrients, sleep, and GWG were calculated. Mediation models were constructed using SPSS PROCESS macro using a bootstrap estimation approach with 10,000 samples. The majority of women were non-Hispanic Caucasian (78.6%). A total of 35.7% (n=10), 35.7% (n=10), and 28.6% (n=8) were normal weight, overweight, and obese, respectively, with 83.3% (n=10) and 87.5% (n=14) of the Control and Breezing™ groups gaining above IOM GWG recommendations. At baseline, macronutrient consumption did not differ. Overall (Breezing™ vs. Control; M diff=-349.08±150.77, 95% CI: -660.26 to -37.90, p=0.029) and late (M diff=-379.90±143.89, 95% CI:-676.87 to -82.93, p=0.014) changes in energy consumption significantly differed between the groups. Overall (M diff=-22.45±11.03, 95% CI: -45.20 to 0.31, p=0.053), late (M diff=-23.16±11.23, 95% CI: -46.33 to 0.01, p=0.05), and early (M diff=20.3±10.19, 95% CI: -0.74 to 41.34, p=0.058) changes in protein differed by group. Nocturnal total sleep time differed by study group (Breezing vs. Control; M diff=-32.75, 95% CI: -68.34 to 2.84, p=0.069). There was a 11.5% increase in total REE throughout the study. Early changes in REE (72±211 kcals) were relatively small while late changes (128±294 kcals) nearly doubled. Interestingly, early changes in REE demonstrated a moderate, positive correlation with rates of GWG later in pregnancy (r=0.528, p=0.052), suggesting that REE assessment early in pregnancy may help predict changes in GWG. Changes in macronutrients did not mediate the relationship between the intervention and GWG, nor did sleep mediate relationships between dietary intake and GWG. Future research evaluating REE and dietary composition throughout pregnancy may provide insight for appropriate GWG recommendations.

Maternal health and mental health have recently become globally recognized as critical areas of focus. The continued research into the relationship between maternal health and mental health—in particular, how they are affected by public policy and infrastructure—is vital to the improvement of general health outcomes. An investigation of literature, current health landscape and indicators, gray literature, and the current policy landscape in an exemplar country (Australia), Bangladesh and Nepal was done. Bangladesh and Nepal were chosen due to the recent amounts of change seen in each country’s maternal health status. Both Bangladesh and Nepal are severely lacking in official mental health services, facilities, and personnel. The analysis revealed flaws and disparities in each country’s current policy landscape. Despite these disparities it should be recognized that policies and programs are being implemented – just in a very piecemeal manner, and not entirely by each country’s respective government. Integration of maternal health services and mental health services is recommended to improve functionality of already existing services. The addition of minimal but necessary components to health systems is recommended.

Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

WHO estimates that 830 women die every day due to maternal health complications. The disparities in maternal health are unevenly distributed between wealthy and poor nations. Ethiopia has one of the highest mortality rates in the world. Existing high maternal mortality rates worldwide and in Ethiopia indicate the shortcomings of maternal health interventions currently underway. Understanding the socio-cultural, economic and political factors that influence maternal health outcomes locally while simultaneously examining how global reproductive and development programs and policies shape and influence the reproductive needs and knowledge of women is important. Employing feminist and African indigenous methodologies, in this research I explore maternal health issues in Ethiopia in two of the largest regions of the nation, namely Oromia and Amhara, more specifically in Seden Sodo and Mecha districts. Using qualitative interviews and focus group discussions, I examined the various socio-cultural, political and economic factors that influence maternal health outcomes, assessing how gender, class, education, marriage and other social factors shape women's health outcomes of pregnancy and childbirth. I also explored how global and local development and reproductive health policies impact women's maternal health needs and how these needs are addressed in current implementation strategies of the Ethiopian health system. Recognizing women's social and collective existence in indigenous African communities and the new reproductive health paradigm post-ICPD, I addressed the role of men in maternal health experience. I argue that global and local development and reproductive policies and their implementation are complex. While comprehensive descriptions of national and maternal health policies on paper and gender-sensitive implementation strategies point toward the beginning of a favorable future in maternal health service provision, the global economic policies, population control ideas, modernization/development narratives that the nation employs that focus on biomedical solutions without due emphasis to socio-cultural aspects have a detrimental effect on maternal health services provision. I advocate for the need to understand and include social determinants in policies and implementation in addition to legal enforcement and biomedical solutions. I also argue for alternative perspectives on masculinities and the role of men in maternal health to improve maternal health service provision.

2015 marks the deadline for the UN Millennium Development Goal 5 to reduce global maternal mortality rate (MMR) by 75% since 1990. As of 2015, MMR has only been reduced by 45%. Many international organizations claim that more medically trained midwives can meet global maternal health care needs. This study investigates two major questions. What is the role of midwives in diverse international maternal healthcare contexts? How do midwives in these different contexts define their roles and the barriers to providing the best care for women? From May to August 2015, I conducted over 70 interviews with midwives in Netherlands, Sweden, Rwanda, Bangladesh, Australia and Guatemala, interviewing between 6 and 13 midwives from each country. The majority of midwives defined their roles as supporting women's individual capacities and power through normal birth, and knowing when to refer when high-risk complications arise. Although thematic barriers vary by country, midwives in all countries believed that maternal healthcare can be improved by increased collaboration between midwives and other health care professionals, better access to culturally appropriate services, and greater public awareness of the role of midwives.

Policy trends show that pregnant women have been detained in ICE facilities since as early as 2015. As the laws and policies have continued to shift, pregnant women have become more exposed to being detained. Executive Order 13768 made by former President Donald Trump effectively removed all protections against being detained for pregnant women. While the previous policy exempted pregnant women from being detained aside from in extraordinary cases, this executive order puts women at increased risk of being detained while pregnant. The Trump Administration's goal of protecting the American people and promoting national security puts women in a position in which their health status is no longer seen as a detention exemption. There is almost no published work on this topic. It is extremely under-researched and there is an urgent need for more academic, legal, and medical research on the impacts of detaining pregnant women. This paper functions to fill a very pressing research gap in order to highlight the experiences of pregnant women in detention centers and the health outcomes they face as a result of their status as detainees. I argue that detaining pregnant women is a form of gendered violence as it puts them at increased risk of maternal health complications, such as preterm birth, low birth weight, and more. While more women migrate to the United States, the laws and policies regarding detaining pregnant women are often contradictory and it is difficult to ascertain the true number of pregnant women in detention centers. In this paper, I examine the preceding factors to female migration, the climate of detention in the United States, the policies regarding pregnancy, and the outcomes that women experience.

This research highlights the experiences of mothers diagnosed with preeclampsia and HELLP syndrome through qualitative data analysis of social media comments. I collected 300 comments from the Instagram accounts @preeclampsia.foundation and @HELLPsyndrome. The two overarching themes found were: (1) Experiences with maternal healthcare and (2) Virtual Healing Spaces. These Instagram accounts represented unique communities that provide support and information that cannot be found elsewhere. These findings address gaps in the literature on maternal experience with preeclampsia and HELLP syndrome and identify directions for further research. The conclusions drawn add to current research that points to the need for reform in maternal healthcare.

The goal of this thesis was to better understand the lived experiences of an ethnically and linguistically diverse sample of mothers who gave birth during the COVID-19 pandemic. Pregnant women experience higher risk for severe COVID-19 outcomes compared to non-pregnant women. Yet the impact on women’s psychosocial wellbeing may be just as problematic, given new mothers’ increased risk for depression postpartum coupled with the loss of multiple forms of support so critical during the postpartum period and new stressors created by the pandemic. A universal testing strategy at a Labor & Delivery Unit at a hospital in the Southwestern U.S early in the pandemic identified that Communities of Color – particularly resettled refugee women - experienced COVID-19 infection at higher rates compared to White women. Therefore, this study investigates stressors and coping strategies specific to the pregnancy, birth, and postpartum periods in a linguistically diverse sample of 140 women (Swahili n=18 , Kinyarwanda n=18 , Burmese n=13, Arabic=11, Spanish n=35, English n=45) who gave birth between May and December 2020. Across groups, the most severe health stressor was fear of self or infant contracting COVID-19, leading to strict adherence to prevention measures among women, and feelings of social isolation. This was followed by anxiety for lack of social support at birth, and, in some women, management of other health concerns related to increased risk for adverse pregnancy or severe COVID-19 outcomes. Coping strategies included looking to religion or spirituality for comfort, as well as spending more time with family. This analysis of how the pandemic affected women’s psychosocial wellbeing from pregnancy to postpartum informs adaptation of care for linguistically and ethnically minoritized groups and their infants.

There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity

for Unmanned Aerial Vehicles.

Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate

these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.
