▼ Educators in the social studies content area have struggled for over a century with how to best instruct their students in critical thinking. A growing group of researchers in the discipline of history, one of the major components of social studies education, support teaching the domain-specific skills of historical thinking through the process of historical inquiry. Nevertheless, many social studies teachers lack the pedagogical content knowledge to instruct their students in historical thinking skills through historical inquiry. This multiple case study sought to examine how two social studies teachers might change their knowledge, beliefs and practices after engaging in eight historical inquiry professional development sessions. The professional development in historical inquiry incorporated many characteristics shown to be effective based on research studies. The theoretical frameworks for the study included social constructivist learning theory, expert/novice learning theory, and teacher change theory. Analysis of data from teacher and student interviews, teacher surveys, classroom observations, teacher reflective journals, artifact review, and audio recordings of the professional development sessions revealed significant patterns within and across the two case study participants. Changes observed in the teachers’ knowledge, beliefs and practices indicated they were able to instruct their students in historical thinking skills through historical inquiry within their respective curriculums. However, both teachers faced the challenges of curriculum design and time constraints, and students’ varied developmental and motivation levels. Findings from this study have implications for how to support social studies teachers as they develop pedagogical content knowledge in historical inquiry in order to teach their students historical thinking skills.

▼ If students are to be successful in the ever-changing scientific world they need to be taught how to think critically, to manipulate materials, and to gather evidence to build knowledge. Most teachers fall short in providing students the inquiry instruction described in the Next Generation Science Frameworks (National Research Council, 2011). This study examined three elementary science teachers’ processes as they developed inquiry practices over time. The Electronic Quality of Inquiry Protocol (EQUIP) was used to gather quantitative and qualitative evidence of the teachers’ inquiry practices in terms of four factors, Curriculum, Instruction, Discourse, and Assessment. A chronological analysis was used to examine the teachers’ professional development and curriculum experiences in relation to their teaching practices. The results showed that all three teachers did change their practice, although the changes varied among cases. For each case, multiple factors influenced the teachers’ development. There was a strong positive correlation between the quality of the teachers’ inquiry practices and the time spent in curriculum-contextualized professional development. This research indicates that when teachers are supported with curriculum and professional development over extended periods, they develop exemplary inquiry practices. Three recommendations are provided for those interested in implementing science education reform.

▼ Using the social constructivist lens, I frame a call for action that advocates for the use of critical literacy and a protocol for discussion in the English language arts classroom. Salon authentic discussion will present teachers with a powerful new pedagogy for critical literacy instruction in the secondary ELA classroom especially in this critical time when standards and accountability for both students and teachers is being redefined.
As a teacher-researcher, I am in the best position to investigate how students can become equipped to meet proficiency in speaking and listening a standards based era. Using grounded theory methodology, I examine authentic discussion that has the power to stir controversy, recognize the claims of others, and continually engage participants in the search for identity and meaning (Ayers, 2004).
An investigation into the literature reveals the difficulties associated with conducting authentic discussion as well as the gap in the literature that provides educators with the necessary ingredients for its success. Grounded theory emerges in an argument advocating the use of a combination of literary theory, social motivation, Accountable Talk, and critical literacy that can be used to best prepare senior high school students for authentic literary discussion. Most importantly, the study’s findings point to the need to make students comfortable in the classroom, finding ways to allay their fears of embarrassment, and ensuring that social justice and tolerance is integral part of the classroom community.

▼ Instructional leadership is focused on elevating teaching and learning for the purpose of improved student achievement (King, 2002). There are many styles of school leadership represented in educational leadership research, yet there is not an abundance of research on high school teachers’ perspectives regarding instructional leadership. The purpose of this study was to examine the phenomenon of effective instructional leadership through teachers’ experiences. Using six core practices of effective instructional leadership as the frame for the phenomenological study, eight teachers were interviewed from two high schools in two school districts in Rhode Island. Four teachers from each school shared their experiences and provided details about what they understood to be an effective instructional leader through one-on-one interviews. Using transcendental phenomenology as the methodology to analyze the interview data, I compared and contrasted the findings of teachers at both high schools. My conceptual framework was based primarily on the works of Darling- Hammond, Meyerson, LaPointe, and Orr (2010) and Leithwood, Harris, and Hopkins (2008). I analyzed the data by developing structural and textural themes to examine the teachers’ experiences in describing the phenomenon of effective instructional leadership. The result of this study is a composite textural-structural description of the essence of the core practices that embody effective instructional, school leadership. The study focuses on how the teachers have made sense of and understood the practices of instructional leaders. The major core essence is building interpersonal skills with teachers through setting goals, establishing open communication, and building trust. This study offers a unique view into teachers’ lived experiences and perspective of effective instructional leadership.

▼ As American higher education proceeds with the internationalization process of the undergraduate curriculum, college and university campuses continue to advocate for higher levels of study abroad participation among the student population. Originating from a tradition that perceived involvement as a luxury for a select few, these experiences are now commonly viewed as a means for the general student body to develop the knowledge and the 21st century skills required to fully engage the global context in which we live. Despite the continued expansion in the number of students participating, the general profile of participants has remained stubbornly similar, with individuals of “lower” socioeconomic standing and social class origins consistently identified as being underrepresented in these programs.
This investigation aims to better understand this low-income segment of the student population by researching the experience of Pell Grant recipients who did study abroad to determine what factors supported their decision to proceed with participation. The study also seeks to better understand these students’ experience while abroad and upon reentry into their domestic social networks. Employing Seidman’s (2006) structure for in-depth, phenomenological interviewing as a guide, a three-interview series was used to explore the experience of 17 students at a public flagship university in the northeast region of the U.S. Theoretical concepts of social and cultural capital developed by Pierre Bourdieu are utilized to frame the study and to analyze the constructed discourse, as well as to foreground issues of social class and status.
The analysis revealed two groups of low-income participants roughly distinguished by parents’ educational levels and associated social and cultural capital of their families. By examining the discourse of these study abroad alumni, the objective is to produce knowledge that can be used to gain a more robust understanding of these participants to better inform international educators how to encourage and support participation, to expand these opportunities to this population, and to gain deeper insight into how to effectively support them throughout the study abroad process. Recommendations for international educators and further research are suggested.

▼ Seismograms are the result of the complex interactions between a seismic source, a propagation medium and the seismograph's response. Through the use of 3-dimensional modeling and full seismic waveform data, we quantify and minimize errors associated with the source and propagation medium within our data sets. We compile a new and unique earthquake catalog for the Middle East that is openly available to the public. We quantify the benefits of using a 3-dimensional model relative to a 1-dimensional model to minimizing error in earthquake moment tensors and identify where in the waveform 3-dimensional models outperform 1-dimensional models. Two new and unique 3-dimensional seismic wave speed models are computed for the Ontong Java plateau and eastern North American margin.Both models are significant improvements to the resolution of wave speed structures in the crust and upper mantle and provide new information for the evaluation of tectonic features.

▼ Introduction: Atrial fibrillation (AF) is a very common condition that causes cardiac rhythm disturbance and affects 2.7 to 6.1 million individuals in the United States (US). Warfarin, which is considered as a gold standard anticoagulant for the last 50 years to treat AF has limitations pertaining to the risk of bleeding, interaction with drugs and requires frequent monitoring. Novel Oral Anti-Coagulants (NOAC including dabigatran and rivaroxaban) are new promising drugs which have shown better or similar efficacy to lower stroke risk and fewer side effects compared to warfarin in the clinical trials. To compete with warfarin, NOACs may need to demonstrate substantial real-world evidence in regards to improving clinical outcomes and cost savings.
Objective: The study was designed to evaluate the extent of undertreatment (adherence), and its predictors along with the impact of adherence on clinical outcomes, including ischemic stroke, bleeding, and Deep Vein Thrombosis and Pulmonary Embolism (DVTPE). Furthermore, the analysis helped to estimate the economic burden of NOACs vs. warfarin and identify specific subgroups with high-cost drivers and Healthcare Resource Utilization (HCRU) to achieve optimal benefits and devise strategies for cost-savings. The objective was achieved by conducting the following studies:
Study 1 - To examine patterns of medication adherence (measured by Proportion of Days Covered [PDC]) in patients with atrial fibrillation taking NOACs vs. warfarin for 6 or 12 months (post index). Furthermore, the study examined the short and long-term factors predicting adherence to the NOAC therapy after controlling potential confounders.
Study 2 - To examine the impact of adherence on the short and long-term risk of ischemic stroke, bleeding DVTPE and recurrent DVTPE in patients with AF taking NOACs during a one-year period (post index). The impact of adherence on outcomes was investigated by comparison of risk among propensity-matched adherence (adherent vs. non-adherent) cohorts.
Study 3 – To describe and compare the economic burden (cost and HCRU) in patients using NOACs vs. warfarin therapy. Furthermore, the study aimed to identify specific subgroups and key drivers of high-costs and HCRU. The final aim of the study was to explore if there are any differences in cost/HCRU between adherent and non-adherent NOAC patients.
Methods: The research utilized a retrospective cohort study design. Atrial fibrillation patients (ICD-9-CM codes 427.31/32), with ≥2 prescription fills for NOAC or warfarin, CHA2DS2VASC score ≥1, and 6-months pre-index continuous enrollment from the Optum® Clinformatics™ Data Mart (Optum Insight, Eden Prairie, MN) (Jan 1, 2010 and Dec 31, 2012) were included. The index date was the first prescription claim for NOAC or warfarin. Adherence was calculated using Proportion of Days Covered (PDC) over a 1-year period. Predictors of adherence (PDC ≥ 80%) were examined using a logistic regression model controlling for the covariates including age, gender, stroke risk, co-morbidities, insurance…

▼ Distributed sensing refers to the solution which enables the real-time, continuous measurement at multiple sensing locations (typically, more than 100 sensing nodes). Due to many of its unique advantages, such as small size, light weight, low cost, electromagnetic immunity, high-temperature survivability, and chemical stability, optical fibers have been well accepted as one of the most promising candidates as the platform for distributed sensing applications.
Among different fiber distributed sensing methods, optical frequency domain reflectometry (OFDR) represents a particular promising candidate. Based on the frequency modulated continuous wave (FMCW) method, OFDR method is capable of measuring the spatial-continuous weak Rayleigh scattering patterns along the entire length of the fiber under test, with high spatial resolution (~μm) level and moderate interrogation distance (~ km). To extract the structural information from the unmodified communication grade single mode fiber, large interrogation bandwidth is needed. However, this resource of optical bandwidth is very expensive. The external cavity laser is the state-of-the-art frequency sweep laser source for OFDR system, which costs at least $ 20,000. The cost has rendered the OFDR interrogation technique expensive and limits its applications.
This dissertation focused on the improvement of OFDR interrogation system by reducing the total system cost. First, a series of sub-terahertz range fiber sensors, including Fabry-Perot cavity sensors and terahertz fiber grating sensors were symmetrically investigated. Fabricated using femtosecond laser micromachining techniques, these sensors allow the OFDR system for low bandwidth interrogation while maintaining the high accuracy measurement. In addition, a sensor fabrication method without stripping the fiber polymer buffer was developed. This is the first time that an in-line grating structure has been fabricated within the core of an optical fiber with an intact buffer coating, allowing the fiber to retain optimal mechanical properties.
Second, a series of low cost sweep laser sources were developed as high-linear coherent sweep laser source, suitable for the sub-terahertz range fiber sensor interrogation. Based on current injection modulation methods, the semiconductor lasers were used as the sweep laser sources and the output wavelength was feedback controlled using optical phase locked loop techniques. The method of using VCSEL laser was also investigated to increase the sweep bandwidth. In addition, an all-digital optical phase locked loop system was implemented using the field programmable gate array, which increases the system design flexibility.

▼ This dissertation presents two variants of Cops and Robbers that feature asymmetric movement, meaning that the cops and robber have different rules for traversing the edges of the graph. The first variant discussed is the bridge-burning variant, wherein the game is played on an undirected graph and the robber deletes any edge he traverses. The second variant discussed is the weak directed variant, wherein the game is played on a directed graph; here the cops can only move along each edge in the direction it points, whereas the robber can traverse each edge in either direction. In both variants, we will be looking at the cop numbers for well-known classes of graphs.

▼ The postsecondary landscape has changed drastically in the past 40 years, with one of the most obvious changes being the increased reliance on adjunct or part-time faculty. Approximately 50% of the current faculty employed by postsecondary institutions are categorized as part-time faculty, up from approximately 25% in 1975 (American Association of University Professors, 2017; Snyder, de Bray, & Dillow, 2016). While there is literature surrounding the impacts of this phenomenon, the majority of studies are entrenched in a positivist framework, utilize quantitative methods, and many use large datasets to distill down whether students are more or less successful when taught by part-time faculty. Very few studies utilize the voices and examine the lived experiences of part-time faculty, especially in regards to how they develop their pedagogical skills as teachers.
A retrospective case study methodology was utilized to fill this gap in the literature. Seven part-time faculty members who teach in the natural sciences from various four-year institutions located in Southern New England were interviewed regarding their teaching experiences throughout their career, as well as their experiences with professional development through this time. The Novice to Expert Skill Model (Dreyfus & Dreyfus, 1980) was used as a theoretical framework. During analysis of the interview data, several key findings emerged.
Based on the experiences of the participants, part-time faculty teach fairly similarly to full-time faculty: They want to make science relevant to their students, teach using alternative teaching practices, and make personal connections with their students. It was also found that part-time faculty proceed along the Novice to Expert Skill Model as it is described, with the exception of their beginning stage – many of the participants identified as more developed than the Novice stage when they began teaching. Several of the female participants showed a reluctance to admit they self-identified as Experts, while other participants were overly confident in their development. Participants identified peer interactions, self-drive, and funding as positive impacts to their pedagogical development. Participants identified “being thrown in the classroom” with no support, spotty observations by superiors, mechanical and forgettable workshops, and feeling like a “second-class citizen” as having a negative impact to the development of their pedagogical skills. Participant experiences point out a need for institutions and departments to recognize the motivations and needs of the adjunct faculty they have on staff currently, without making assumptions of adjunct faculty in general. Recommendations for institutional and departmental professional development policies are included.

▼ Sustainability is defined as “meeting the needs of the present generation without compromising the ability of future generations to meet their own needs.” (WCED, 1987). This is a concept that was developed to counteract the negative consequences of the culture of disposability and consumption based economy on the environment. Many policy makers have the perception that pursuing policies that embrace sustainability would compromise countries economic prosperity. Therefore, this dissertation introduces the new index of sustainable prosperity. This is a novel multiattribute measure that comprehensively assesses sustainable prosperity (SPI) for systems such as countries, hospitals, and products…etc. This index ensures that adapted policy contribute to progress toward sustainable development and equally important maintain the wealth of the system. Herein, we demonstrated its utility by applying it on the country case represented by the G-20 group.
We investigated the drivers for culture of disposability and made recommendation on expanding the definition of disposable products to better define its contribution to GDP. Furthermore, the major sustainability indices that act as tools in the assessment of sustainability were investigated. The goal is to identify a viable index to comprehensively assess sustainability and the key attributes for a good measure. While valid, each index had its own disadvantages that limited their use. A list of attributes that should be considered to develop an index that successfully measures the progress of nations toward sustainable development was developed (Table 4.6). These attributes were used as a frame of reference for the SPI index and the selection of the domains and sub-domains that are mapped to systems investigated.
The analytical methodology of SPI index is based on the use of Principle Components Analysis (PCA) combined with Data Envelopment Analysis (DEA) (PCA-DEA). This approach discriminates among systems i.e. G-20 countries investigated. It identifies the ones that are sustainable. It incorporates the use of inputs and outputs to calculate the efficiency score of each system investigated i.e. SPI. A total of 44 inputs (Chapters 6 and 7) were mapped to the domains and sub-domains of the framework. In addition, a total of 10 outputs were selected to capture the wealth of the nations, which is based on the maintenance of capital, or keeping capital stock least unchanged as proposed by Dasgupta (Dasgupta 2010 ). Initially, conventional DEA was implemented to calculate countries SPI. Since there was a large number of inputs and outputs utilized (a total of 54 variables) relative to the number of countries investigated (20 DMUs), this methodology fell short of discriminating among the G- 20 countries. Indeed, all countries were sustainable and acquired an SPI score of 1. Therefore, PCA was used to reduce the number of variables and transform the original inputs and outputs into principle components with minimal loss of information (capturing most of the original variance of the…

▼ Rates of substance use among juvenile offenders are disproportionately high and frequently associated with deviant and criminal behavior (Mulvey, Schubert, & Chassin, 2010). Despite the prevalence of group-based treatment for adolescent substance abuse (Young, Dembo, & Henderson, 2007), some authors caution that aggregation of high-risk youth may increase rather than decrease antisocial behavior, thus producing iatrogenic effects. The current study sought to identify the extent to which various group processes as rated by counselors, observers, and adolescents mediate the relationship between type of group treatment received while incarcerated and adolescents' substance use and conduct problems following their release. Of the group processes investigated, only deviancy training (i.e., peers reinforcing each others' antisocial acts during group sessions) was differentially impacted by treatment type as rated by counselors and observers. Treatment differences were not found when using adolescent ratings, suggesting that adolescents may be less able to meaningfully assess their own behaviors during group treatment. Using multiple mediation, simple mediation, and moderated mediation analyses, no evidence was found in support of the claim that deviancy training during group treatment is related to poorer outcomes, or iatrogenic effects. This finding remained consistent across the three different perspectives (i.e., observers, counselors, adolescents) of deviancy training for all substance use outcomes examined at 3- and 6-months post-release. The indirect effect of treatment type was insignificant across all models examined. Findings indicate the effect of treatment on substance use outcomes post-release is not mediated by deviancy training, or any of the other group processes investigated.

▼ This work addresses the effectiveness of energy efficiency (EE) incentive programs in reducing electricity consumption and assisting states in meeting their energy policy goals. EE programs provide financial incentives to encourage consumers to make investments in energy efficient equipment and reduce energy consumption. This study carries out a quantitative analysis to provide insights into EE programs performance. In two empirical applications, the research examines program performance on two levels: national coverage including all US-based utilities in the first application and state performance in the second application.
The first empirical application examines stipulated energy savings from electric utilities across all states and compares the outcome to an econometric model that estimates savings from observed consumption. This study examines panel data from the contiguous US spanning eleven years from 2005 to 2015, to estimate the effect of EE program total expenditures on electricity demand. We find that although EE investments have been effective in reducing energy consumption, the modeled magnitude of these energy savings implies that EE programs have had a smaller effect on energy consumption than claimed by electric utilities over the same period.
The results imply a price elasticity of energy efficiency ranging between 0.29 - 0.54; indicating a rebound effect. Consequentially, energy savings are less than proportional to the increase in energy efficiency. However, consumers benefit from an increase in energy services, since they get more of the service, for less cost.
The second empirical application examines the cost-effectiveness of state-specific EE programs. The application employs econometric analysis to mimic an experimental research design using observational data from states with different energy policies in EE investments. This methodology evaluates program performance between states with aggressive EE policies and states with moderate programs. The differential effect of EE program implementation (treatment) in those states is examined in the context of a difference in differences approach and synthetic control method. The study examines the performance of the state with the highest per capita investments in EE: the state of Rhode Island.
We assessed the energy efficiency policy of Rhode Island and compared its outcome to Maine and New Hampshire. Findings suggest that there is not a statistically significant effect on residential consumption, as a result of the substantial increase in EE expenditure, in RI during the period 2008 to 2015. However, a re-evaluation of the Rhode Island EE policy, using the synthetic control method (SCM) identifies that by the year 2015, annual per-consumer residential electricity consumption in Rhode Island was 97 kWh (1.34%) lower, on average, than it would have been in the absence of the increased EE programs.
The research also identifies that energy efficiency improvements have welfare implications on various levels: individual, local, national and…

▼ In the United States of America, oyster production is an important component of the seafood economy in many communities in coastal states. The severe impact of disease outbreaks and mass mortality of oyster larvae in hatcheries impacts production, since the oyster industry is largely dependent on hatchery and nursery production. The use of probiotics has been proposed as a potential preventative measure to limit the impact of bacterial diseases in shellfish hatcheries. In previous laboratory studies, the probiotic bacteria Phaeobacter inhibens S4 and Bacillus pumillus RI06-95 improved the survival of eastern oyster (Crassostrea virginica) larvae against the pathogens Vibrio tubiashii RE22 (now V. coralliilyticus) and Roseovarius crassostreae CV919-312T (now Alliroseovarius crassostreae). The aim of this study is to evaluate the efficacy of candidate probiotics P. inhibens S4 and B. pumillus RI06-95 for disease prevention in shellfish hatcheries.
Chapter 1 provides an overview of bacterial disease in marine bivalves and the use of probiotics for disease prevention in bivalve hatcheries. Chapter 2 describes that the daily application of P. inhibens S4 and B. pumillus RI06-95 mixed with algal feed to culture tanks in the hatchery increased survival of oyster larvae to experimental challenge with V. coralliilyticus RE22. The levels of total Vibrios in water and surfaces of tanks treated with probiotics were significantly decreased (p < 0.05) compared to non-treated tanks, whereas there were no significant differences between treatments in levels of Vibrios in oysters. These probiotic strains had no significant impact on oyster larvae growth and survival rate at the hatchery.
Chapter 3 evaluates the safety and efficacy of candidate probiotic bacteria strains, P. inhibens S4 and B. pumilus RI06-95, in four bivalve species, including hard clams Mercenaria mercenaria, bay scallops Argopecten irradians, blue mussels Mytilus edulis, and razor clams Ensis directus. Pre-exposure of larvae to 104 CFU/ml of probiotics for 24 h in the laboratory did not protect these bivalve species to challenge with V. coralliilyticus RE22, but pre-exposure to 106 CFU/ml probiotics S4 and a mixture of S4 and RI did confer some protection to bay scallop larvae (RPS; 69 ± 4 %). Daily application of 104 CFU/ml probiotics to tanks with bay scallop larvae at the hatchery offered partial protection against bacterial infection without impacting levels of Vibrios in tank surfaces, water, and larvae. However, although daily probiotic treatment of tanks containing hard clam larvae led to a decrease in the levels of Vibrio sp. in rearing water and larvae, it provided no consistent protection to bacterial challenge.
Chapter 4 evaluates the effects of formulation methods on the viability and efficacy of two formulations of B. pumilus RI06-95, including a granulated (43 μm in size) and a lyophilized (containing 100 mM sucrose as a cryoprotectant) formulation. Granulation led to a decrease in cell viability from 108 CFU/mg to 105 CFU/mg. This level of viability…

▼ This work was motivated in part by Austin Becker’s 2013 dissertation, Building Seaport Resilience for Climate Change Adaptation: Stakeholder Perceptions of the Problems, Impacts, and Strategies, which surveyed global port authorities’ perceptions and plans for climate change adaptation and found a disconnect between perceptions of climate impacts and a lack of policies to address them. That work called for the development of a nationwide risk and vulnerability index for ports as a next step in the climate adaptation process for seaports. Climate change adaptation was found to be in the early planning phase for most ports globally, and assessing vulnerabilities is a recommended first step in risk-reduction.
In the face of climate change impacts projected over the coming century, seaport decision makers have the responsibility to manage risks for a diverse array of stakeholders and enhance seaport resilience against climate and weather impacts. At the single port scale, decision makers such as port managers may consider the uninterrupted functioning of their own port the number one priority. But, at the multi-port (regional or national) scale, policy-makers will need to prioritize competing port climate-adaptation needs in order to maximize the efficiency of limited physical and financial resources and maximize the resilience of the marine transportation system as a whole. Such multi-port decisions can be supported by information products such as indicator-based composite indices that allow for objective assessment of relative vulnerabilities among a sample of ports.
To that end, this work, consisting of three distinct but theoretically related manuscripts, advances the state of data-driven Climate Impact Adaptation and Vulnerability (CIAV) decision-support products for the seaport sector by assessing the current state of vulnerability assessments for seaports (manuscript 1), compiling and refining a set of candidate indicators of seaport climate and extreme-weather vulnerability from open-data sources for 23 major seaports of the United States’ North Atlantic region and creating and applying a Visual Analogue Scale (VAS) instrument for expert-evaluation of the candidate indicators (manuscript 2), and finally by applying the Analytic Hierarchy Process (AHP) with port-experts to weight a selection of the indicators to examine the suitability of the indicator-based vulnerability assessment (IBVA) approach and available open-data to create a composite index of relative climate and extreme-weather vulnerability for the sample of ports.
The first manuscript in this work provides an overview of a variety of approaches that set out to quantify various aspects of seaport vulnerability. It begins with discussion of the importance of a “multi-port” approach to complement the single case study approach more commonly applied to port assessments. It then addresses the components of climate vulnerability assessments and provides examples of a variety of approaches. Finally, it suggests an opportunity exists for further research and…

▼ A disparity exists between the medical intervention people say they want to receive at end-of-life and the care that is typically delivered. Advance care planning (ACP) involves discussing end-of-life care wishes, including relevant values and cultural beliefs, and documenting these preferences for medical providers and loved ones to minimize unwanted suffering and maximize quality of life. Numerous healthcare institutions have emphasized the importance of doing ACP prior to an imminent medical need, prompting researchers to implement awareness campaigns and interventions in earlier stages of healthcare interactions (e.g., primary care). However, motivation to follow through with ACP varies depending on numerous factors including overall readiness, understanding of the risks and benefits, and how one manages the internal experience of facing one’s own mortality. One intrinsic experience that has been shown to be important for health behavior change is situation specific-confidence, or self-efficacy. This work builds on previous research that approaches ACP intervention from the theoretical framework of the Transtheoretical model (TTM) of behavior change, in which self-efficacy is a core component. Study 1 of this dissertation sought to explore the construct of self-efficacy specific to doing ACP with qualitative work including expert interviews and focus groups with older adults in the community about their experiences. The work presented describes the efforts to understand self-efficacy as a barrier to engagement in end of life care planning. Self-efficacy was associated with interpersonal support, access to structured tools to guide discussions, and tolerance of the unpleasantness of negative emotions. Assessment of themes from focus groups and expert interviews was conducted to write items of a scale of self-efficacy to do ACP. Study 2 of this dissertation describes the development and validation of a scale of ACP self-efficacy using a sequential approach to measure development. Qualitative and quantitative methods were utilized for item development/refinement and scale validation. Split-half validation procedures were conducted, with exploratory and confirmatory factor analyses on randomly selected subsamples. The results of several iterations of exploratory factor analyses supported a final set of 12 items loading on one factor, with high internal consistency. The final 12-item ACP self-efficacy scale was found to have good overall model fit in confirmatory analyses, assessed with χ2 tests of significance and fit indices. Further, the developed scale was validated using previously developed TTM measures of ACP behavior change (Stage of Change, Decisional Balance) and related constructs (General Self-Efficacy, Attitudes Values & Cultural Beliefs). As expected, ACP self-efficacy varied by stage of change, with those in more progressed stages endorsing higher levels of confidence that they could complete ACP behaviors, upholding the relationships hypothesized by the TTM. Together, these two studies address the…

▼ The goal of the research is to critically analyze co-management as a tool for sustainable marine resource management through improved understanding of stakeholder participation in co-management. This critique is based on the underlying hypothesis that co-management will lead to greater representation and participation of stakeholders in management and that successful co-management is that which encompasses a wide range of stakeholder perspectives in the decision-making process. This study investigates variability in the involvement of stakeholders in selected examples of existing co-management arrangements developed to manage marine reserves within the wider Caribbean. An understanding of the factors contributing to and dynamics of stakeholder participation is essential for promoting effective resource co-management. As a way of understanding the success of governance arrangements in reserve management, a comparative analysis of several sites has been conducted to ascertain some of the factors influencing the extent of stakeholder participation in co-management arrangements, including the importance of social networks in fostering knowledge of and participation in management. A secondary objective of this dissertation is to use network analysis to determine what impact the underlying social network has on the co-management arrangement, and on stakeholder participation in co-management.
This dissertation seeks to answer the following questions: 1) How do social networks affect participation?; 2) What is the relationship between successful co-management and social networks?; 3) What does successful co-management look like?
Additionally, management recommendations are provided to improve co-management processes at each of the MPAs included in this study. This research includes six marine protected areas from around the Caribbean with some form of co-management in place selected as case studies. Residents of the communities adjacent to the marine protected areas were surveyed about their participation in management activities and about their knowledge of individuals responsible for making decisions about the marine protected area. Responses were analyzed to uncover factors that may influence participation by community members, and a social network analysis was conducted for each of the study sites based on the names provided by respondents. The effect of social network characteristics on participation is discussed, and the qualities of successful co-management are enumerated.

▼ This study examines underwater acoustic propagation in a shallow water environment, concentrating upon the impact of nonlinear internal waves. During internal wave activity, acoustic signals can fluctuate significantly due to complex three-dimensional multi-mode and multipath interference effects. Experimental measurements from the Shallow Water '06 experiment provide oceanographic and acoustic data during instances where the acoustic track is nearly parallel to an approaching internal wave train. Distinct events show internal waves modulate the acoustic field substantially. Propagation modeling using the Monterey-Miami Parabolic Equation algorithm simulates an internal wave train moving in a straight-line fashion. Horizontal refraction dominates in the nearly parallel configuration, and three specific scenarios are exemplified in both measured and modeled data: refraction (prior to the internal wave's arrival), defocusing (as a soliton spreads acoustic energy), and focusing (as two solitons create a horizontal sound channel). Normal mode decomposition and statistical analysis provide insight into the temporal and spatial acoustic fluctuations. At very small angles off-parallel, focusing effects are dramatically reduced, and refraction prior to the internal wave's arrival becomes an important factor to consider. In the exactly parallel scenario, refraction remains important, but is a second order effect compared to focusing.

▼ Existing research and theories have consistently highlighted the role of emotion regulation deficits and parental psychological control in the occurrence of childhood anxiety disorders. The aim of the present study was to continue to examine these relationships using observational methods amongst a clinically anxious sample. Additionally, the present study aimed to identify the direction of effects between parental psychological control and emotion dysregulation by examining whether there is a discernible sequence of parent and child behaviors forming a pattern of interaction between parents and their anxious children. This was completed using microanalytic coding methods to observe parental psychological control and child dysregulated emotion in moment-to-moment interactions between parents and their child. Time-window sequential analyses was used to identify whether parents were more likely to display psychological control in response to child dysregulated affect than at other times and whether children were more likely display dysregulated affect in response to parent psychological control than at other times. In a sample of 123 clinically anxious and 53 non-clinical children, ages 8 to 12 years, results indicated that anxious children were observed to display longer durations of dysregulated affect than non-clinical children, and parents of anxious children were observed to display longer durations of psychological control than parents of non-clinical children. Results from time-window sequential analyses indicated that children were more likely display dysregulated affect in response to parent psychological control than at other times. Anxiety disorder status did not moderate this relationship; however, race was found to moderate the relationship when examining a 4-second time-window. Findings support theories highlighting the role of parental psychological control and emotion dysregulation deficits among children with anxiety disorders and further elucidate the nature of parent-child interactions with respect to parental psychological control and emotion dysregulation.

▼ The use of radiation is broad in biological systems, in different areas of research mostly in health.
Radiation is used to kill cancer. In radiation therapy proper calculation is done so that a maximum dose is delivered to the cancer. Inspite of this precaution, radiation effects healthy tissue. This effect is especially dangerous when the tumor is located near important organs. Thus in radiation therapy, it is important to reduce the dose and the damage to the healthy tissues and organs. The damage on the healthy tissues due to radiation therapy in cancer could be reduced by reducing the radiation dose to get the same treatment effect or by enhancing the radiation. The enhancement of radiation effect in vitro and in vivo can be obtained by targeted drug delivery on the cancer. Also photo dynamic therapy can be supplemented by the use of radiation therapy on the cancer by targeted drug delivery.
Another use is the development of a bio dosimeter. In a large scale nuclear event it is important to measure the radiation dose exposed to humans. Also it is likely that the people who are exposed to radiation are not wearing the dosimeter. So a method of estimating radiation dose to a person exposed to radiation without a physical dosimeter would be a very useful procedure. One possible method is the use of gene expression analysis, which is based on the fact that the expression of the genes will change due to the absorbed radiation. So developing a biological dosimeter based on the gene expression analysis could quantify the radiation dose given to the patients during radiation therapy or to assess the risk of cancer developing in the general population. This biological dosimeter could even be used when the physical dosimeters are insufficient to estimate the risk caused by the radiation exposure or even years after being exposed to nuclear accidents.
The main goal of the work presented here is to investigate the following topics Use of gold pHLIP to enhance the radiation effect in cancer cells Review on the in vivo research done to enhance radiation using gold nanoparticles Analyze the gene expression results from irradiated drosophila melanogaster to develop a biological dosimeter. Use of X-ray to activate targeted Copper Cysteamine nanoparticles photosensitizer to reduce tumor size in mice.
A review work I have done on the researches related to enhancement of radiation using gold nanoparticles in tumor bearing mice showed that the targeted nanoparticles are a promising method for achieving radiation enhancement due to their shape, size, surface chemistry and the properties of the nanoparticles.
Gold nanoparticles are susceptible to X-rays compared to tissues and release extra electrons by Auger effect when the tumor treated with gold is irradiated. These auger electrons have low energy and are localized within the tumor site killing the cancer cells. However tumor targeting peptide pHLIP (pH Low Insertion Peptide) conjugated to gold nanoparticle specifically targets low pH medium (tumor) which when irradiated reduces…

▼ The aim of this thesis is to design, develop and test a new portable system for digital forensics imaging with real-time analysis over every live file. Currently large magnetic hard drives are infeasible to perform sequential imaging taking over 40 hours to complete before beginning with any forensic analysis. Attempted approaches included performing a limited (sparse) collection and performing a distributed live analysis using a high-end server environment, neither of which would be sufficient for field use. I designed and developed the code to test the system and developed comprehensive testing scenarios. I show that magnetic disk fragmentation has a direct, mostly linear impact over the speed at which a disk can be imaged and every live file be processed simultaneously. I show that RAM has a near exponential impact on simultaneous magnetic disk forensic imaging with all live file processing. I demonstrate that CASE/UCO has the potential to be the interoperable file format for digital forensics metadata exchange. I also demonstrate that a system for simultaneous forensic disk imaging with all live file analysis can be assembled with commercial off-the-shelf parts for less than $1000.

▼ This study examined how adjusting the degree of school involvement and types of recruitment channel relate to research recruitment effectiveness in both rural and urban high-school populations. Presently, there is a lack of consensus in the literature on the most useful media based channel or cost-effective strategy for sampling adolescents in school-based research. This study represents the second of a two-phased exploratory trial to determine effectiveness and cost-efficiency of examined methods to recruit adolescents to participate in online research. Varying combinations of social media channels (QR codes, Facebook ads) and degrees of school involvement (none, passive, active) were implemented at six different high schools, and a systematic tracking method was implemented to maintain involvement fidelity in each of the six schools. The results revealed that the combination of using QR Codes with active level of school involvement recruited the highest sample response percentage, but generated the highest cost per recruited participant; whereas QR Codes combined with no school involvement recruited the second lowest recruitment percentage but generated the second lowest recruitment cost per participant. Furthermore, in both rural and urban communities, there appeared to be a strong pattern of decreased cost-effectiveness of using social media for recruitment as the amount of school involvement increased. This is the first known study to examine QR Codes and Facebook combined with varying amounts of school involvement; as well as the first known study that seeks to understand how adjusting the amount of school involvement relates to recruitment effectiveness and cost-efficiency in this context. The findings are interpreted from a variety of theoretical and conceptual frameworks, including implementation feasibility, method sustainability, and cost-effectiveness.

▼ This thesis presents the design of ultra-low power Phase-Locked Loops (PLLs) intended for applications in the extended audio range. The PLL is well suited for battery operated systems, where small size and low power operation are crucially important. The two implementations presented are based on current controlled relaxation oscillator and a ring oscillator intended for the same frequency range. The frequency is controlled by a current that can vary from 2 to 74 nA. Using a reference frequency of ¼ of the typical watch crystal frequency, the user can select any integer multiple of 8.192 kHz up to the maximum of 122.88 kHz. The PLL circuits operate from a single 3 V supply and, depending on the actual output frequency, dissipate between 0.9-2 μW of power.
This work also investigates phase jitter in PLLs. Expressions for the period jitter caused by the current noise as well as the voltage noise present on the two rails (Vdd and Vref) are derived. The theoretical results reveal that the current noise establishes a lower bound for jitter, which scales as the inverse of the square root of the selected current. The numerical result has been put to test by two practical circuits, which consume between 300-660 nA of current and produce frequencies between 8.192-122.88 kHz. The measurements confirmed that the computed lower bound serves as a realistic estimate of the actual performance.

▼ Marine sediments harbor metabolically versatile bacteria whose activities can influence the cycle of nutrients on global scales. Microbial communities driving nitrogen (N) cycling are extremely diverse, thus making it difficult to identify the functional groups and elucidate controls on their activity. Denitrifiers in sediments remove significant amounts of N from the coastal ocean, while diazotrophs are typically considered inconsequential. Recently, N fixation has been shown to be a potentially important source of N in coastal sediments, however, the environmental drivers controlling this process are poorly understood. The goal of this dissertation was to identify and target the likely active denitrifiers and N fixers in coastal marine sediments through the analysis of genes expressed for proteins essential for denitrification, a nitrite reductase (nirS) and nitrogen fixation, a nitrogenase subunit (nifH). Subsequently, quantitative PCR and RT-PCR were used to follow the changes in abundance, distribution and nifH expression of the dominant diazotrophic groups in response to environmental conditions. Two groups of diazotrophs related to anaerobic sulfur/iron reducers and sulfate reducers dominated nifH expression in Narragansett Bay (RI, USA) sediments. Increased seawater temperature and severe hypoxia appear to be influencing the proliferation and activity of these two bacterial groups. Oxygen depletion also affects sediment porewater nutrients, indicating a shift in benthic microbial processes. In offshore sediments, nifH expression was related to UCYN-A, a unicellular cyanobacterium. These findings suggest that UCYN-A, a known tropical and subtropical open ocean symbiont, has a broader thermal tolerance than previously assumed and can survive in the benthos after the lifespan of its eukaryotic host. Diazotrophic activity by these microbial communities in marine sediments is an unanticipated contribution of fixed N to coastal systems. Climate change may exacerbate the environmental conditions in which these microbes become active, consequently altering the global marine nitrogen cycle in unprecedented ways.

TROPHIC ECOLOGY OF OXYGEN MINIMUM ZONE ZOOPLANKTON REVEALED BY CARBON AND NITROGEN STABLE ISOTOPES.

▼ Oxygen minimum zones (OMZs) are areas in which midwater oxygen concentration can be significantly lower than in non OMZ areas at comparable depths. OMZs are of great interest because of the limits oxygen availability places on life. The potential for OMZ expansion with warming of the oceans has refocused attention on the importance of these areas and their potential impacts on the global carbon cycle. The large open ocean OMZs of the Eastern Tropical Pacific and Arabian Sea are notable for their size, thickness, and the intensity of oxygen depletion (
Here, I use measurements of natural abundance carbon and nitrogen stable isotopes (as δ13C and δ15N, respectively) to investigate zooplankton diets within the Eastern Tropical Pacific OMZ. The use of stable isotopes rests on the premise that the δ13C values of consumers are similar to their ultimate organic carbon source, primary producers, while the δ15N values reflect more proximal sources of organic matter and can be used to evaluate trophic position. To examine the energy sources and trophic interactions of zooplankton in the Eastern Tropical North Pacific OMZ, samples were collected in 2007 and 2008 at two stations, the Tehuantepec Bowl (TB) and Costa Rica Dome (CRD), using vertically stratified MOCNESS net tows between 0-1200 m. Environmental data were collected concurrently with zooplankton samples and particulate organic matter (POM) was collected with McLane large volume in situ pumps. Zooplankton samples were separated into four size fractions and processed at sea to select aliquots for bulk (mixed zooplankton) analysis and individual taxa samples were analyzed for stable carbon and nitrogen isotopes.
Bulk zooplankton and POM δ13C and δ15N values revealed strong depth gradients associated with oxyclines (oxygen gradients) at the upper and lower OMZ boundaries. While the source of low δ13C values at the upper oxycline could not be determined, the sharp gradient in δ15N values at the lower oxycline indicated a depth zone of increased trophic progression. Furthermore, δ15N values were significantly lower at CRD than at TB, suggesting that nitrogen fixation may have been present at CRD. Low δ13C-δ15N correlations in all zones at CRD suggested that the products of nitrogen fixation were transferred to zooplankton food webs throughout the sampled water column.
Stable isotope values of individual zooplankton taxa also suggested that zooplankton collected within and above the OMZ core likely fed on material from the upper 110m of the water column, while lower oxycline zooplankton likely consumed deep POM exiting the OMZ. There were significant differences in the isotope values of zooplankton taxa with different trophic strategies (particle feeders, omnivores, carnivores) in the OMZ core and lower oxycline community, but not for those living in the mixed layer and upper oxycline. Furthermore, calculated trophic levels for lower oxycline taxa were much higher than expected based on a priori trophic level designations. The copepod Eucalanus inermis is thought to diapause…

▼ This Ph.D. dissertation presents a process-oriented study with two primary objectives: 1) to obtain a physical understanding of the impacts of local and remote forcing, including basin-scale natural climate variability, on the interannual variability of along-shelf transport and water properties of the Middle Atlantic Bight (Chapter 1); 2) to explore the impacts of physical processes on the seasonal variation of phytoplankton biomass in Rhode Island coastal waters (Chapter 2). To achieve the two objectives, we apply a numerical modeling approach employed by the Regional Ocean Modeling System (ROMS) together with substantive analyses of both in-situ and remote observations.
Chapter 1 focuses on the interannual-to-decadal variability of along-shelf transport and water properties of the Middle Atlantic Bight (MAB). A suite of process oriented numerical experiments is designed for separating local and remote forcing in order to explore their contributions to the interannual-to-decadal variability of along-shelf transport. Results show that the low-frequency variability is dominated by remote forcing from the open boundaries of the region. The penetration of the Labrador Current into the region contributes to a significant increase of along-shelf transport in the winters of 2009 and 2010. By contrast, the anticyclonic mesoscale eddies associated with the Gulf Stream have a negative impact on the along-shelf jet, and in certain cases even reverse the along-shelf transport. The along-shelf transport is also found to possess a decadal transition, i.e. weaker during 2004-2008 but stronger during 2009-2013.
Chapter 2 focuses on the mechanisms controlling the seasonal variation and spatial distribution of phytoplankton biomass in Rhode Island (RI) coastal waters. We first apply an Empirical Orthogonal Function (EOF) analysis to a nine-year monthly chlorophyll-a dataset in order to determine the spatial/temporal structure of the signal. The first EOF mode shows that the spatial variations of chlorophyll-a are in phase from the RI coast to the outer shelf, and the temporal variations are dominated by the strong seasonal cycle characterized by a broad peak during the fall-winter months (October to March). The spatial distribution of chlorophyll-a indicates that the phytoplankton biomass decreases with distance offshore as the water depth increases. To understand the mechanisms controlling the abovementioned features, we first set idealized one-dimensional (1-D) numerical experiments, using a physical-biological model (ROMS-NPZD), to isolate advective processes. Results show that the fall-winter bloom is initiated by enhanced vertical turbulent mixing, which results from the combined effects of the increased surface momentum forcing and surface cooling, bringing nutrients up into the euphotic zone. The extensive mixing also has a counteractive effect on the fall-winter bloom as phytoplankton are carried below the euphotic layer. A three-dimensional (3-D) experiment is then conducted to validate the key conclusions drawn from 1-D…

▼ The prevalence of diabetes, a chronic illness, is expected to substantially rise over the next fifteen years (Whiting, Guariguata, Weil, & Shaw, 2011). One approach to ease the burden on the US health care system is the involvement and participation of family in care of the hospitalized adult. There is increasing evidence that involvement of family during exacerbations and hospitalizations increases client and family satisfaction during admissions and may also decrease length of stay and therefore cost (Powers & Rubenstein, 1999). The purposes of this study were to examine family members’ perceptions of family functioning, family health and the social support received from nurses when an older adult family member with diabetes is hospitalized. Also examined were nurses’ critical appraisals of their family nursing practice, as well as their experiences of the reciprocity and interaction in the nurse-family relationship. This study further explored the relationships between nurses’ critical appraisals of their family nursing practice and nurses’ experiences of the interaction and reciprocity in the nurse-family relationship with families’ perceptions of family function, family health and perceived social support from nurses. Finally, this study examined if nurses’ critical appraisal of their family nursing practice, and nurses’ experience of the interaction and reciprocity in the nurse-family relationship, differed across nursing units, and what the impact was on families’ perceptions of family function, family health and social support received. Wright and Leahey’s Calgary Family Intervention Model (CFIM) (1994) undergirded this descriptive study, which was conducted on four medical-surgical units in a community hospital. Sixty registered nurses and sixty family members of older adult patients participated. Two instruments were used to address the variables of interest in this study. Family member participants completed the Family Function, Family Health and Social Support Instrument (Astedt-Kurki, Tarkka, Paavilainen, & Lehti, 2002; Astedt-Kurki, Tarkka, Rikala, Lehti, & Paavilainen, 2009) as well as a demographic questionnaire. Registered Nurse participants completed demographics and the Family Nursing Practice Scale (Simpson & Tarrant, 2006). Significant variation was found across the four study units in how nurse participants reflected on their experiences with interaction and reciprocity in the nurse-family relationship. However, family member participants had no significant variation in their perceptions of family functioning, family health and social support received from nurses. This research informs practice by providing insight into nurses’ perceptions regarding the advantages and the disadvantages of working with families. Additionally, this study contributes evidence of what nurses are currently doing to include families in their nursing practice. More research is needed which focuses on collaboration and inclusion of families in care of their loved one.

▼ There is a growing epidemic of obesity in the United States and a corresponding increase in the number of morbidly obese patients receiving healthcare. Despite the increasing focus and research on obesity over the years, the prevalence of obesity in the United States has continued to worsen. A stigma against obesity exists in the general public including among healthcare professionals. Attitudes and bias of healthcare professionals against obesity can negatively affect judgment and choices related to the enactment of care, affecting both the quality of healthcare delivered and patient outcomes. Studies have shown that stigmatization against groups of patients such as minorities affects healthcare outcomes, however there is a paucity of research related to outcomes of stigmatization against obese individuals. The purpose of the study was to determine if there is a difference in quality of nursing care as measured by medicating for pain between obese and non-obese post-surgical patients. It was hypothesized that obese individuals will receive less pain medication than non-obese individuals. An underlying assumption based on the literature was that stigmatization of obesity by nurses would be reflected in reduced administration of post-surgical pain medication. The greater the stigma present, the less pain medication will be administered.
This study used a retrospective chart review of the electronic medical record of three hospitals within a single healthcare system to compare non-bariatric post- surgical pain treatment among normal weight, over-weight, and obese adult patients as a measure of nurses’ stigma. The final data set contained a total of 1704 cases, with 21.4% (n=365) normal weight, 21.4% (n=365) overweight, 21.4% (n=365) obesity class I, 17.1% (n=291) obesity class II, and 18.7% (n=318) obesity class III individuals. BMI scores ranged from 18.5 to 185.9 (M = 33.1, SD = 11.1). Findings showed differences in total dose of day one post-surgical pain medication among the normal, overweight, obesity class I, II, and III patients. Obesity class III patients received less pain medication than the obesity class I and class II patients and significantly less than the overweight patients. Simple linear regression analyses were used to determine the relationship between BMI and pain medication administration on postoperative day one and day two. Hierarchical linear regression was used to determine the relationship between dose on day one and day two and BMI, while taking into account other variables associated with stigma. The relationship between dose of pain medications and BMI was significant and negatively related. For every 1% increase in BMI there was a .17% decrease in the total morphine equivalent dose of narcotic given on postoperative day one. When controlling for other factors related to stigma, there was a .25% decrease in dose for every 1% increase in BMI. Further research is needed to measure attitudes and biases of nurses along with their administration of pain medication to obese patients. Addressing…

▼ The Schlicht class of functions, commonly denoted as S, is the class of univalent functions defined on the unit disk such that f (0) = 0 and f’(0) = 1. This is a well-studied class for which many results are known. We prove that there exists a bounded sequence of polynomials, and a Fatou component for this sequence, such that for all f ∈ S, there exists a subsequence of iterates of compositions of our polynomial sequence for which f is a limit function.

WAVE-INDUCED SEDIMENT TRANSPORT: SIMULATION OF TURBULENT WAVE BOUNDARY LAYERS.

▼ Two manuscripts are presented which develop a numerical method for studying boundary layer flow and sediment transport on the seafloor. Inviscid flow, either through an analytic solution or a numerical wavetank (NWT) is used to force a previously developed three-dimensional Navier-Stokes model. The resulting hybrid model is able to simulate complex turbulent flows near the ocean bottom or around obstacles.
The first manuscript reports on developments of a perturbation approach to large-eddy simulations (LES) of wave-induced boundary layers. In the present formulation, the total velocity and pressure fields are expressed as the sum of irrotational and near-field viscous perturbation, where the irrotational field is known a priori. The LES equations are formulated and solved for the perturbation fields only, which are forced by the known incident fields. Results are presented for laminar oscillatory boundary layers, as well as for laminar steady streaming induced by small-amplitude waves, which show convergence to known analytic solutions. To demonstrate potential applications, forcing from a two-dimensional NWT is applied, showing the steady streaming that exists in a laminar boundary layer under large-amplitude water waves. Results are also shown for turbulent oscillatory boundary layers, which agree well with published experimental data.
The second manuscript presents LES results of sediment transport over vortex ripples. A conformal mapping is used to match the computational domain to an experimentally derived shape of vortex ripples formed in a large-scale oscillatory water tunnel. While the instantaneous velocity field and time-averaged velocity field agrees reasonably well with published experimental data, the time- and rippleaveraged velocity profile differs substantially. As well, the suspended sediment concentration above the ripple crest is substantially different than that observed experimentally. These effects, likely the result of insufficient resolved turbulent intensity in the LES, result in poor predictions of suspended sediment transport rates.
