Accounting for Comprehensive Safety: Intimate Partner Violence, Marginalization, and Institutional Response

This dissertation examines the ways intimate partner violence (IPV) survivors' experiences of poverty, mental illness, social isolation, and gender inequality shape their opportunities to protect themselves and their children before, during, and after separating from abusive partners. Ethnographic research was conducted in three communities in the United States over two years. In each site I observed and interviewed women about their experiences of abuse and their attempts to achieve long-term security. I also observed and interviewed practitioners across a range of disciplines about their work with IPV survivors. The results of this study demonstrate that when women ended abusive relationships they often sustained a variety of losses related to their economic stability, social support, and access to their children. After leaving their batterers, many survivors faced debt, trauma, and protracted custody disputes that continued to disrupt their lives. However, the IPV interventions studied were routinely designed as though the collateral damage to an IPV survivor's life ended when she left her abuser. Interventions rarely accommodated survivors' post-separation social, economic, and parenting needs, and indeed, often placed additional strain on women's lives. As a result, the most disadvantaged survivors often found institutional resources in the domestic violence service system inaccessible, irrelevant, and at times counterproductive. This dissertation demonstrates that IPV is more than a series of isolated acts by individual people: it is the cause of many women's diminished agency and heightened suffering long after their abuse has ended

An Ethical History of Photography in Combat and of Combat Photography in the United States during World War II

With the United States‘ entry into the Second World War, the word ?censorship? was seen largely as antithetical to, rather than a necessary counterpart to, victory among Americans. People did not want to be censored in their writing, photographs or speech,but it proved to be necessary even before the war began, in order to protect government secrets and the people on the home-front from scenes that were too disturbing. Even before the war had officially begun, there were problems with censorship among journalists and newspapers. The initial response of outrage in reference to censorship in the United States was common among journalists, newspapers, magazines, and radio news; nevertheless, there was a necessity for censorship among Americans, on the home frontand the front lines, and it would be tolerated throughout the war to ensure that enemies of America did not gain access to information that would assist in a defeat of the United States in the Second World War. The research I have conducted has dealt with the censorship of combat photography during World War II, in conjunction with the ethics that were in play at the time that affected the censors. Through exploring the work of three combat photographers — Tony Vaccaro, James R. Stephens and Charles E. Sumners — I wasable to effectively construct an explanatory ethical history of these three men. Research on the censorship and effects it had on the United States brought me to three distinctareas of censorship and ethics that would be explored: (1) the restrictions and limitations enforced by the Office of Censorship, (2) a general overview of war and photography as it influenced the soldiers and their families on the home-front, (3) and the combat photographers and personal and military censorship that influenced their work. Although their work was censored both by the military and the government, these men saw the war in a different light that remained with them long after the battles and war had ceased.Using the narratives of Tony Vaccaro, Charles E. Sumners and James R. Stephens as means for more in depth research, this thesis strives to create lenses through which to view the history and ethics of censorship that shaped combat photography during the Second World War and the images to which we refer as representative of that war today

Navigating environmental, economic, and technological trade-offs in the design and operation of submerged anaerobic membrane bioreactors (AnMBRs)

Anaerobic membrane bioreactors (AnMBRs) enable energy recovery from wastewater while simultaneously achieving high levels of treatment. The objective of this study was to elucidate how detailed design and operational decisions of submerged AnMBRs influence the technological, environmental, and economic sustainability of the system across its life cycle. Specific design and operational decisions evaluated included: solids retention time (SRT), mixed liquor suspended solids (MLSS) concentration, sludge recycling ratio (r), flux (J), and specific gas demand per membrane area (SGD). The possibility of methane recovery (both as biogas and as soluble methane in reactor effluent) and bioenergy production, nutrient recovery, and final destination of the sludge (land application, landfill, or incineration) were also evaluated. The implications of these design and operational decisions were characterized by leveraging a quantitative sustainable design (QSD) framework which integrated steady-state performance modeling across seasonal temperatures (using pilot-scale experimental data and the simulating software DESASS), life cycle cost (LCC) analysis, and life cycle assessment (LCA). Sensitivity and uncertainty analyses were used to characterize the relative importance of individual design decisions, and to navigate trade-offs across environmental, economic, and technological criteria. Based on this analysis, there are design and operational conditions under which submerged AnMBRs could be net energy positive and contribute to the pursuit of carbon negative wastewater treatment.This research work was possible thanks to project CTM2011-28595-C02-01/02 (funded by the Spanish Ministry of Economy and Competitiveness jointly with the European Regional Development Fund and Generalitat Valenciana GVA-ACOMP2013/203), and by the King Abdullah University of Science and Technology (KAUST) Academic Partnership Program (UIeRA 2012-06291), which are gratefully acknowledged.

Systems-Based Training in Graduate Medical Education for Service Learning in the State Legislature in the United States: Pilot Study

Background: There is a dearth of advocacy training in graduate medical education in the United States. To address this void,the Legislative Education and Advocacy Development (LEAD) course was developed as an interprofessional experience, partnering a cohort of pediatrics residents, fourth-year medical students, and public health students to be trained in evidence-informed health policy making. Objective: The objective of our study was to evaluate the usefulness and acceptability of a service-based legislative advocacy course. Methods: We conducted a pilot study using a single-arm pre-post study design with 10 participants in the LEAD course. The course’s didactic portion taught learners how to define policy problems, research the background of the situation, brainstorm solutions, determine evaluation criteria, develop communication strategies, and formulate policy recommendations for state legislators. Learners worked in teams to create and present policy briefs addressing issues submitted by participating Illinois State legislators. We compared knowledge and attitudes of learners from pre- and postcourse surveys. We obtained qualitative feedback from legislators and pediatric residency directors. Results: Self-reported understanding of the health care system increased (mean score from 4 to 3.3, P=.01), with answers scored from 1=highly agree to 5=completely disagree. Mean knowledge-based scores improved (6.8/15 to 12.0/15 correct). Pediatric residency program directors and state legislators provided positive feedback about the LEAD course. Conclusions: Promising results were demonstrated for the LEAD approach to incorporate advocacy training into graduate medical education

Effect of light intensity, light duration and photoperiods in the performance of an outdoor photobioreactor for urban wastewater treatment

[EN] A series of eight experiments were carried out to analyse the effects of light intensity, light duration and photoperiods on a microalgae culture for treating AnMBR effluent at an outdoor photobioreactor (PBR) plant. Improved performance was achieved in terms of nutrient recovery rates, biomass productivity and effluent nutrient concentrations at a higher net photon flux. However, the higher irradiance was also responsible for lower biomass productivity:light irradiance ratios. None of the experiments with different lighting regimes and the same net photon flux showed any significant differences. The data obtained suggest that microalgae performance in this system did not depend on the time of day when light was applied or the length of the photoperiods, but on the net photon flux. No photoinhibiton was observed in any of the experiments, probably because of the significant shadow effect on the microalgae in the PBRs.This research work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO, Projects CTM2014-54980-C2-1-R, CTM2014-54980-C2-2-R, CTM2011-28595-C02-01, and CTM2011-28595-C02-02) jointly with the European Regional Development Fund (ERDF), both of which are gratefully acknowledged.

Long-term impacts of prenatal synthetic glucocorticoids exposure on functional brain correlates of cognitive monitoring in adolescence

The fetus is highly responsive to the level of glucocorticoids in the gestational environment. Perturbing glucocorticoids during fetal development could yield long-term consequences. Extending prior research about effects of prenatally exposed synthetic glucocorticoids (sGC) on brain structural development during childhood, we investigated functional brain correlates of cognitive conflict monitoring in term-born adolescents, who were prenatally exposed to sGC. Relative to the comparison group, behavioral response consistency (indexed by lower reaction time variability) and a brain correlate of conflict monitoring (the N2 event-related potential) were reduced in the sGC exposed group. Relatedly, source localization analyses showed that activations in the fronto-parietal network, most notably in the cingulate cortex and precuneus, were also attenuated in these adolescents. These regions are known to subserve conflict detection and response inhibition as well as top-down regulation of stress responses. Moreover, source activation in the anterior cingulate cortex correlated negatively with reaction time variability, whereas activation in the precuneus correlated positively with salivary cortisol reactivity to social stress in the sGC exposed group. Taken together, findings of this study indicate that prenatal exposure to sGC yields lasting impacts on the development of fronto-parietal brain functions during adolescence, affecting multiple facets of adaptive cognitive and behavioral control

Epigenetic Effects of Prenatal Stress on 11β-Hydroxysteroid Dehydrogenase-2 in the Placenta and Fetal Brain

Maternal exposure to stress during pregnancy is associated with significant alterations in offspring neurodevelopment and elevated maternal glucocorticoids likely play a central role in mediating these effects. Placental 11β-hydroxysteroid dehydrogenase type 2 (HSD11B2) buffers the impact of maternal glucocorticoid exposure by converting cortisol/corticosterone into inactive metabolites. However, previous studies indicate that maternal adversity during the prenatal period can lead to a down-regulation of this enzyme. In the current study, we examined the impact of prenatal stress (chronic restraint stress during gestational days 14–20) in Long Evans rats on HSD11B2 mRNA in the placenta and fetal brain (E20) and assessed the role of epigenetic mechanisms in these stress-induced effects. In the placenta, prenatal stress was associated with a significant decrease in HSD11B2 mRNA, increased mRNA levels of the DNA methyltransferase DNMT3a, and increased DNA methylation at specific CpG sites within the HSD11B2 gene promoter. Within the fetal hypothalamus, though we find no stress-induced effects on HSD11B2 mRNA levels, prenatal stress induced decreased CpG methylation within the HSD11B2 promoter and increased methylation at sites within exon 1. Within the fetal cortex, HSD11B2 mRNA and DNA methylation levels were not altered by prenatal stress, though we did find stress-induced elevations in DNMT1 mRNA in this brain region. Within individuals, we identified CpG sites within the HSD11B2 gene promoter and exon 1 at which DNA methylation levels were highly correlated between the placenta and fetal cortex. Overall, our findings implicate DNA methylation as a mechanism by which prenatal stress alters HSD11B2 gene expression. These findings highlight the tissue specificity of epigenetic effects, but also raise the intriguing possibility of using the epigenetic status of placenta to predict corresponding changes in the brain
