Metallicities of 0.3<z<1.0 Galaxies in the GOODS-North Field

We measure nebular oxygen abundances for 204 emission-line galaxies with redshifts 0.3<z<1.0 in the Great Observatories Origins Deep Survey North (GOODS-N) field using spectra from the Team Keck Redshift Survey (TKRS). We also provide an updated analytic prescription for estimating oxygen abundances using the traditional strong emission line ratio, R_{23}, based on the photoionization models of Kewley & Dopita (2003). We include an analytic formula for very crude metallicity estimates using the [NII]6584/Halpha ratio. Oxygen abundances for GOODS-N galaxies range from 8.2< 12+log(O/H)< 9.1 corresponding to metallicities between 0.3 and 2.5 times the solar value. This sample of galaxies exhibits a correlation between rest-frame blue luminosity and gas-phase metallicity (i.e., an L-Z relation), consistent with L-Z correlations of previously-studied intermediate-redshift samples. The zero point of the L-Z relation evolves with redshift in the sense that galaxies of a given luminosity become more metal poor at higher redshift. Galaxies in luminosity bins -18.5<M_B<-21.5 exhibit a decrease in average oxygen abundance by 0.14\pm0.05 dex from z=0 to z=1. This rate of metal enrichment means that 28\pm0.07% of metals in local galaxies have been synthesized since z=1, in reasonable agreement with the predictions based on published star formation rate densities which show that ~38% of stars in the universe have formed during the same interval.

Assessing Opportunities to Improve Sedation/Analgesia Use in Neonatal Patients on ECMO

Background: Sedation is used during ECMO to prevent agitation. Analgesia is used to dampen pain perception as neonatal procedural pain related stress is associated with later altered neurodevelopment with poorer perceptual reasoning and visual perception. Common sedatives/analgesics used during ECMO are opiates and benzodiazepines. Studies have shown that lipophilic drugs such as Fentanyl and Midazolam are significantly sequestered in the circuit suggesting opportunities to improve delivery for pain. Hypothesis and Methods: We hypothesized opportunities to improve sedation/analgesia drug treatment in ECMO patients. Using a retrospective analysis of all neonatal patients receiving ECMO between 2015-2020, we aimed to assess the relationship between sedative/analgesia type and dose and clinical complications. We identified patient demographics, medication type, dose used, days to wean, length of hospital stay, mortality, medical complications at discharge and MRI results. Results: 49 patients were included, mean gestational age 37.6 wks ±3.6. Seventeen (35%) infants died. Race was not associated with mortality. All patients received Fentanyl and Midazolam with one patient who also received Morphine infusion. Fentanyl and Midazolam dose during ECMO was associated with risk for oxygen at discharge 296 vs 517 mcg/kg/days for Fentanyl (p=0.04), and 358 vs 2598 mcg/kg/days for Midazolam (p=0.002) as well as need for feeding tube at discharge 272 vs 420 mcg/kg/days for Fentanyl (p=0.049) and 1.03 vs 1.60 mg/kg/days for Midazolam(p=0.04). Risk for abnormal MRI was increased with Fentanyl ECMO dose exposure (p=0.016). Male gender was associated with greater fentanyl dose exposure by 27% (p=0.038). Conclusion: Fentanyl and Midazolam increased dose exposure was associated with increased risk for later neurological clinical complications in infants undergoing ECMO. Further studies are needed to assess serum drug concentrations in ECMO patients to better understand development of drug tolerance, circuit sequestration and dose exposure to adjust the therapeutic range of sedation and analgesia use

Coral restoration – a systematic review of current methods, successes, failures and future directions

Coral reef ecosystems have suffered an unprecedented loss of habitat-forming hard corals in recent decades. While marine conservation has historically focused on passive habitat protection, demand for and interest in active restoration has been growing in recent decades. However, a disconnect between coral restoration practitioners, coral reef managers and scientists has resulted in a disjointed field where it is difficult to gain an overview of existing knowledge. To address this, we aimed to synthesise the available knowledge in a comprehensive global review of coral restoration methods, incorporating data from the peer-reviewed scientific literature, complemented with grey literature and through a survey of coral restoration practitioners. We found that coral restoration case studies are dominated by short-term projects, with 60% of all projects reporting less than 18 months of monitoring of the restored sites. Similarly, most projects are relatively small in spatial scale, with a median size of restored area of 100 m2. A diverse range of species are represented in the dataset, with 229 different species from 72 coral genera. Overall, coral restoration projects focused primarily on fast-growing branching corals (59% of studies), and report survival between 60 and 70%. To date, the relatively young field of coral restoration has been plagued by similar 'growing pains' as ecological restoration in other ecosystems. These include 1) a lack of clear and achievable objectives, 2) a lack of appropriate and standardised monitoring and reporting and, 3) poorly designed projects in relation to stated objectives. Mitigating these will be crucial to successfully scale up projects, and to retain public trust in restoration as a tool for resilience based management. Finally, while it is clear that practitioners have developed effective methods to successfully grow corals at small scales, it is critical not to view restoration as a replacement for meaningful action on climate change

Parental attributions of control for child behaviour and their relation to discipline practices in parents of children with and without developmental delays

Children with developmental delays (DD) are at risk for developing behavior problems. Research suggests that parents’ causal attributions for child behavior are related to parenting. This study investigated this association in parents of children with DD compared to parents of typically developing (TD) children. It specifically focused on attributions of child control by separating these from attributions of responsibility, blame and intent, and from attributions of parent control and responsibility. Fifty-one parents of children with DD and 69 parents of TD children completed two questionnaires. The Written Analogue Questionnaire measured causal attributions. The Parenting Scale measured dysfunctional discipline practices. Parents of children with DD viewed the child’s role in problematic behavior more positively while also viewing misbehavior as more fixed than parents of TD children. Parents of TD children who viewed their child as more in control over misbehavior used less dysfunctional discipline, but this association was not found for parents of children with DD. The results advance understanding of how parents perceive behavior problems in children with DD and the important role these perceptions play in parental behavior management strategies. More importantly, these perceptions relate to discipline practices differently for parents of children with DD compared to parents of TD children, highlighting that parent interventions should be adapted to the specific needs of parents of children with DD

Identity Issues : Situating the Self in Contemporary Native American Literature

The following work is an examination of the way in which Contemporary Native American authors from the United States depict the search for self within their novels. Included in this thesis is an 'Introduction' that examines the development of a sense of identity that is unique to Nat!ve Americans, as well as those factors that shape and in some instances, hinder the development ofsuch a self-perception, such as stereotypes and US government policies. In order to provide a thorough examination of this particular topic, this work examines novels from three Native American authors with varying tribal backgrounds and experiences. These authors include Sherman Alexie, Susan Power and Greg Sarris. As each of these authors has vastly different ties and levels of involvement with their particular Native American heritages, this work is able to examine the differences that arise in the development ofNative self-perceptions when faced with environmental and social variances. In doing so, this work not only highlights the many different forms that Native American self-perceptions take, but also the multiple paths that lead to the development of these identities.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
