Temperature Index Modeling Of The Kahiltna Glacier: Comparison To Multiple Field And Geodetic Mass Balance Datasets, Joanna Young

Geosciences

Glaciers of Alaska, USA, and Northwestern Canada are shedding mass at one of the highest rates of any mountain glacier system, with significant impact at the global and local scales. Despite advances in satellite and airborne technologies, fully characterizing the temporal evolution of glacier mass change in individual watersheds remains a challenge. Temperature index modeling is an approach that can be used to expand on sparse ground observations, and that can help bridge the gap between regional and individual watershed estimates of the time series of glacier mass change. Here we present a study on temperature index modeling of glacier-wide …

New Algorithms For The Compilation Of Glacier Inventories, Christian Kienholz

Geosciences

Glacier inventories are used for many applications in glaciology, however, their manual compilation is time-consuming. Here, we present two new algorithms for the automatic compilation of glacier inventories. The first approach is based on hydrological modeling tools and separates glacier complexes into individual glaciers, requiring a digital elevation model (DEM) and glacier complex outlines as input. Its application to > 60,000 km² of ice in Alaska (~98% success rate) and southern Arctic Canada (~97% success rate) indicates the method is robust if DEMs and glacier complex outlines of good quality are available. The second algorithm relies on glacier outlines and a …

Basal Shear Strength Inversions For Ice Sheets With An Application To Jakobshavn Isbræ, Greenland, Marijke Habermann

Geosciences

Satellite and in situ observations of ice sheet outlet glaciers around the turn of the 21st century showed that rapid changes in ice dynamics are possible and important for the evolution of ice sheets. When attempting to model these dynamic changes the conditions at the ice-bed interface are crucial. Inverse methods can be used to infer basal properties, such as the basal yield stress, from abundant surface velocity observations by using a physical model of ice flow. Inverse methods are very powerful, but they need to be applied with care, otherwise errors can dominate the solution. In this study we …

Seismicity, Seawater And Seasonality: New Insights Into Iceberg Calving From Yahtse Glacier, Alaska, Timothy Chester Bartholomaus

Geosciences

At many of the largest glaciers and ice sheets on Earth, more than half of the annual ice loss occurs through iceberg calving into the ocean. Calving is also responsible for the most rapid ice mass changes, both directly (through the mechanical loss of ice at the terminus) and indirectly (through dynamic thinning of upstream ice initiated by terminus retreat). Yet, the mechanisms and factors that control calving are poorly understood. Recordings of glaciogenic seismic waves, known as "icequakes," produced during iceberg calving offer opportunities for insight that cannot be gleaned through other methods. In order to better understand iceberg …

Carbon Biogeochemistry Of The Eastern Bering Sea Shelf, Jessica Cross

Marine Biology

The uptake of anthropogenic carbon dioxide (CO₂) has caused perturbations to marine biogeochemistry in recent years, including decreasing ocean pH and carbonate mineral saturation states (Ω). Collectively termed ocean acidification (OA), these conditions hinder the growth of calcium carbonate shells and effectively reduce habitat for some marine calcifiers. Given that the Bering Sea is one of the world's most productive marine ecosystems and supports both commercial fishing industries and subsistence communities, it is integral to understand its susceptibility to OA. Here, new observations of the organic and inorganic carbon systems are used to identify mechanisms leading to CO₂ accumulation and …

Online Social Networks To The Rescue: Fulfilling The Ten Essential Public Health Services, Melanie D. Mason, Maureen P. Bezold

Frontiers in Public Health Services and Systems Research

Budget cuts and shortages in the public health workforce have contributed to the reduction of public health services in 91% of state health departments (SHDs). To adjust for these changes, health departments must discover novel ways to deliver essential public health services to their constituents. Researchers conducted a retrospective analysis of the content published on SHDs’ Twitter pages to determine if online social networks were used to fulfill the ten essential public health services. While 42 SHDs had a Twitter page, the volume and content of tweets varied. Although tweets were posted that related to all ten of the essential …

Efficiency In Public Health Service Delivery: An Analysis Of Clinical Health Services Provided By Local Health Departments In Florida, Simone R. Singh

Frontiers in Public Health Services and Systems Research

The ability of local health departments (LHDs) to provide public health services to improve the health of their communities depends to a large extent on their financial resources. More money by itself, however, does not necessarily translate into better population health. LHDs also have to use their resources in an efficient manner to achieve the best possible outcomes. This article first describes two techniques that LHDs can use to assess their efficiency at providing public health services: process costing, a technique used by management accountants, and stochastic frontier analysis, a technique used by economists. Using data for LHDs in Florida, …

Evidence Use In New York City Public Health Policymaking, Miriam J. Laugesen, Kimberley R. Isett

Frontiers in Public Health Services and Systems Research

New York City Mayor Michael R. Bloomberg has attracted national attention for his public health policy reforms. The policy process behind the reform program has received less scrutiny, especially the use of research by policymakers. We show that the process used to develop, promote, and evaluate polices is heavily based on five types of data and research. New York Department of Health and Mental Hygiene staff conducted in-depth appraisals of existing published research, used local health surveys and private laboratory surveillance data, engaged in “shoe-leather” field research, formed research collaborations within and outside government, and disseminated research to legitimize policy …

Commentary: Moving Beyond The Numbers, Effectively Using Research To Influence Policy, F. Douglas Scutchfield, Marylou Wallace

Frontiers in Public Health Services and Systems Research

This seventh issue of Frontiers reflects the variety of PHSSR. One emerging theme, however, is the notion of public health and its role in policy and policy development. PHSSR focuses on several potential users, researchers, practitioners and policy makers. As it concerns policy makers, PHSSR delivers research that allows them to make decisions about policy change that not only influences public health status, but creates healthy conditions. In this way, PHSSR essentially influences decisions about support for public health services.

Phospholipase D- And Phosphatidic Acid-Mediated Signaling In Plant Response To Abscisic Acid And Reactive Oxygen Species, Liang Guo

Dissertations

The Arabidopsis genome has 12 phospholipase D (PLD) genes that are classified into six types, PLDα, PLDβ, PLDγ, PLDδ, PLDε, and PLDζ, based on sequence similarities, domain structures, and biochemical properties. Phosphatidic acids (PA) produced by PLDs have been identified as important lipid signaling molecules in cell growth, development, and stress responses. This study was undertaken to determine the role of PLD and PA in plant response to abscisic acid (ABA) and reactive oxygen species (ROS). The lipid mediator PA was found to interact with sphingosine kinases (SPHKs) in Arabidopsis. Two unique SPHK cDNAs were cloned and expressed. Both SPHKs …

Issues Related To Combining Multiple Speciated Pm2.5 Data Sources In Spatio-Temporal Exposure Models For Epidemiology: The Npact Case Study, Sun-Young Kim, Lianne Sheppard, Timothy V. Larson, Joel Kaufman, Sverre Vedal

UW Biostatistics Working Paper Series

Background: Regulatory monitoring data have been the most common exposure data resource in studies of the association between long-term PM_2.5 components and health. However, data collected for regulatory purposes may not be compatible with epidemiological study.

Objectives: We aimed to explore three important features of the PM_2.5 component monitoring data obtained from multiple sources to combine all available data for developing spatio-temporal prediction models in the National Particle Component and Toxicity (NPACT) study.

Methods: The NPACT monitoring data were collected in an extensive monitoring campaign targeting cohort participants. The regulatory monitoring data were obtained from the Chemical Speciation …

Prediction Of Fine Particulate Matter Chemical Components For The Multi-Ethnic Study Of Atherosclerosis Cohort: A Comparison Of Two Modeling Approaches, Sun-Young Kim, Lianne Sheppard, Silas Bergen, Adam A. Szpiro, Paul D. Sampson, Joel Kaufman, Sverre Vedal

UW Biostatistics Working Paper Series

Recent epidemiological cohort studies of the health effects of PM_2.5 have developed exposure estimates from advanced exposure prediction models. Such models represent spatial variability across participant residential locations. However, few cohort studies have developed exposure predictions for PM_2.5 components. We used two exposure modeling approaches to obtain long-term average predicted concentrations for four PM_2.5 components: sulfur, silicon, and elemental and organic carbon (EC and OC). The models were specifically developed for the Multi-Ethnic Study of Atherosclerosis (MESA) cohort as a part of the National Particle Component and Toxicity (NPACT) study. The spatio-temporal model used 2-week average measurements …

Using Strengths-Based Leadership To Improve The Child Welfare System, Kimberly M. Giardina

Journal of Family Strengths

The child welfare system has primarily focused on the safety of children even though the goals of the system are to improve safety, well-being, and permanency. Through an innovative use of strengths-based leadership and the restructuring of service delivery, the Neighborhoods for Kids program has demonstrated how to effectively achieve all three goals for children in the child welfare system. The unique infusion of strengths-based leadership into the child welfare system allowed staff to creatively meet the outcomes without any additional funding needed. The goal was to strengthen the leadership in East Region and increase staff engagement, which would in …

Commentary On "Using Strengths-Based Leadership To Improve The Child Welfare System", June C. Lloyd

The Cult Of Salomé: Decapitation Imagery And Cultural Anxiety In Belle Époque Europe., Sean C. Hall

Master of Liberal Studies Theses

The Belle Époque in Europe marked a time of great change. Many of the old, yet longstanding traditions were being challenged and modernity really took hold of society at that time. The changes in the social fabric with issues such as the roles of women were common topics of conversation. Women demanded new rights and began to even question the role of masculinity in this new age. This was the emergence of the “New Woman,” and with all of these great changes came great anxiety. This cultural anxiety felt by many was expressed in the arts of the period which …
