Researchers from Kaplan University present findings from a media-rich feedback pilot program that targets students from developmental writing courses. One study of student reactions reveals how screencasting feedback encouraged more formative, holistic feedback and students' awareness of writing process, audience, and revision. A second study comparing grades shows how media-rich feedback had a positive effect on student performance.

In this article, Maryland's non-legal-tender paper money emissions between 1765 and 1775 are reconstructed to determine quantities outstanding and redemption dates, providing a substantial correction to the literature. Over 80 per cent of this paper money's current market value was expected real asset present value and under 20 per cent was liquidity premium. It was primarily a real barter asset and not a fiat currency. The liquidity premium was positively related to the amount of paper money per capita in circulation. This paper money traded below face value due to time-discounting, rather than depreciation. Past scholars have simply confused depreciation with time-discounting. [ABSTRACT FROM AUTHOR]

Topographic map evidence for previously unexplained Casselman River direction changes (including where it joins the Youghiogheny River) indicates prolonged and massive volumes of south-oriented water once flowed across the Conemaugh-Casselman River drainage divide and formed diverging southwest- and southeast-oriented channels with the southwest-oriented flow joining south-oriented flow on today’s north-oriented Youghiogheny River alignment. The southeast-oriented channel eroded a water gap across an emerging Negro Mountain and then a diverging southwest-oriented channel followed the northeast-oriented Casselman River alignment to reach south-oriented flow on the now north-oriented Youghiogheny River alignment while the southeast-oriented channel and a southeast-oriented channel which diverged from the southwest-oriented channel eroded the Flaughtery and Piney Creek water gaps into an emerging Meadow Mountain. Conemaugh River drainage system development ended south-oriented flow into the Casselman River drainage basin while regional uplift caused drainage reversals to create today’s northeast-, northwest-, and southwest-oriented Casselman River.

Recent reports from Japan implicated wild Sika deer (Cervus nippon) in the zoonotic transmission of hepatitis E to humans. Seroprevalence studies were performed to determine if imported feral populations of Sika deer in Maryland and Virginia posed a similar risk of transmitting hepatitis E virus (HEV). Hunters collected blood on filter paper discs from freshly killed deer. The discs were desiccated and delivered to a collection point. The dried filters were weighed to estimate the amount of blood absorbed and were eluted and collected in one tube via a novel extraction system. The procedure was quantified and validated with negative and positive serum and blood samples obtained from domestic Sika deer before and after immunization with HEV recombinant capsid protein, respectively. None of the 155 tested samples contained antibody to HEV, suggesting that Sika deer in these populations, unlike those in Japan, do not pose a significant zoonotic threat for hepatitis E. However, the new method developed for collecting and eluting the samples should prove useful for field studies of many other pathogens.

The Fourth Biomedical Imaging Research Opportunities Workshop (BIROW IV) was held on February 24–25, 2006, in North Bethesda, MD. The workshop focused on opportunities for research and development in four areas of imaging: imaging of rodent models; imaging in drug development; imaging of chronic metabolic disease: diabetes; and image guided intervention in the fourth dimension-time. These topics were examined by four keynote speakers in plenary sessions and then discussed in breakout sessions devoted to identifying research opportunities and challenges in the individual topics. This paper synthesizes these discussions into a strategy for future research directions in biomedical imaging. [ABSTRACT FROM AUTHOR]

Using surveys, interviews, and a rubric-based assessment of student research essays, the St. Mary's College of Maryland Assessment in Action team investigated the relationship between faculty-librarian collaboration in a First Year Seminar (FYS) course and students' demonstrated information literacy (IL) abilities. In gathering information on the experiences, attitudes, and behaviors of faculty, librarians, and first-year students, the project team uncovered additional questions about the integration of IL in the FYS, the ways in which faculty and librarians work towards educational goals, and just what should be expected from students in their first year of college.

Contemporary undergraduates in the biological sciences have unprecedented access to scientific information. Although many of these students may be savvy technologists, studies from the field of library and information science consistently show that undergraduates often struggle to locate, evaluate, and use high-quality, reputable sources of information. This study demonstrates the efficacy and pedagogical value of a collaborative teaching approach designed to enhance information literacy competencies among undergraduate biology majors who must write a formal scientific research paper. We rely on the triangulation of assessment data to determine the effectiveness of a substantial research paper project completed by students enrolled in an upper-level biology course. After enhancing library-based instruction, adding an annotated bibliography requirement, and using multiple assessment techniques, we show fundamental improvements in students' library research abilities. Ultimately, these improvements make it possible for students to more independently and effectively complete this challenging science-based writing assignment. We document critical information literacy advances in several key areas: student source-type use, annotated bibliography enhancement, plagiarism reduction, as well as student and faculty/librarian satisfaction.

This paper examines the genesis of Leo Kanner's 1943 seminal paper on autism. It shows that describing children as autistic or lacking affective contact with people was not new by this time. But Kanner's proposal that infantile autism constituted a hitherto unidentified condition that was inborn and different from childhood schizophrenia was new. It also shows that Georg Frankl's influence on Kanner was important, but Kanner did not misappropriate his ideas or his research. Kanner developed his views on the basis of his observations of several children, his knowledge of the literature on childhood conditions, and his interactions with many scholars.

Maryland is actively working towards doubling its Renewable Portfolio Standard (RPS) target, aiming to increase the share of renewable energy from 25% by 2020 to 50% by 2030. Furthermore, Maryland stands out as a state that strongly supports solar initiatives, offering incentives and specialized programs to assist residents in adopting solar energy solutions. The paper presents a multi-stage approach: Stage 1—Location Selection Process, Stage 2—Technical Feasibility Study, and Stage 3—Economical Feasibility Study. In Stage 1, the study focuses on three potential solar farm locations in Maryland: Westover, Princess Anne, and Eden. Stages 2 and 3 involve a feasibility assessment with detailed technical analysis using the NREL System Advisor Model (SAM) and PVWatts to determine monthly power to the grid and Energy Yield. Subsequently, economic feasibility is assessed using the NREL Clean Renewable Energy Estimation Simulation Tool (CREST), focusing on competitive levelized costs of energy (LCOE), payback time, and cumulative cash flows. Results indicate that all three locations exhibit promising solar irradiance levels, system outputs, and potential energy yields. Due to high solar irradiation, the Westover area has the highest energy yield at 1583.13 kWh/kW, while Princess Anne boasts the highest system output at 333.59 GWh. The economic evaluation suggests that all three locations become profitable within a two-year payback time, with competitive levelized costs of energy (LCOE). Westover emerges as the most cost-effective option at 5.99 cents/kWh, attributed to its higher solar irradiation values and energy yield compared to Princess Anne and Eden. Cumulative cash flows provide insights into long-term profitability, with Princess Anne, MD, having the highest Cumulative Cash Flow over 25 years at $183,383,304. By evaluating technical and economic aspects, this feasibility study offers quantitative insights to guide decision-making for the installation of Solar PV, considering both technological and economic feasibility.

While education accountability systems emphasize teacher quality as a prerequisite for student learning, education administrators have struggled to staff low-performing schools with effective teachers. Fueled in part by the federal Teacher Incentive Fund, compensation reforms have gained center stage status among strategies aimed at improving human capital in schools. This article presents findings from a formative evaluation of the initial year of implementation of the Financial Incentive Rewards for Supervisors and Teachers (FIRST) program in the Prince George's County Public School System. Our review of the relevant theoretical and empirical literature on financial incentive systems in public school systems identified four sets of implementation challenges: securing and maintaining stakeholder support; developing and implementing accurate and credible measures of educator performance; developing the district and site capacity required to implement and sustain the initiative; and aligning the reform with human resource goals, school improvement initiatives, and features of the work environment. Our field research on the formulation, implementation, and initial impact of the FIRST initiative demonstrates that even when an educator incentive initiative reflects "lessons learned" from the empirical and theoretical literature, challenges that undermine the initiative's potential to realize its major goals persist. We argue that this case extends our understanding of the key challenges identified in the literature and we highlight implications for policy and research. (Contains 1 table and 28 notes.)

Several states had an assessment that they considered to be an alternate assessment based on modified academic achievement standards (AA-MAS) in place, or in development, when the April 2007 federal regulations on modified achievement standards were finalized. This article uses publicly available information collected by the National Center on Educational Outcomes to analyze changes in states' AA-MAS between 2007 and 2008. The article compares across the 2 years the number of states that had an assessment they considered to be an AA-MAS, states' participation guidelines, and the characteristics of these assessments. We also provide information about the number of students who participated in this assessment option during the 2006-07 school year. In 2007, six states (Kansas, Louisiana, Maryland, North Carolina, North Dakota, Oklahoma) either had or were in the process of developing an assessment they considered to be an AA-MAS. In 2008, California, Connecticut, and Texas also offered this assessment option. Six of the nine states that have been early implementers of the AA-MAS were states that had offered an out-of-level testing option until federal policies required that option to be phased out. Most states had fewer items on their AA-MAS than on their regular assessment. States that had participation guidelines for the AA-MAS in 2007 developed them prior to finalization of the federal regulations, and some changes between 2007 and 2008 in states' participation guidelines appear to have been made to better align the guidelines with the regulations. The characteristics of the assessments states consider to be AA-MASs are changing rapidly and will probably continue to change rapidly over the next few years as more is learned about the advantages and limitations of this assessment.

Although ambiguity exists regarding how states must respond to the mandates of Fordice to dismantle dual systems of education in previously segregated states, several scholars note Fordice should manifest itself in the enhancement of public Black colleges. Responding to Fordice, the state of Maryland entered into an agreement with the Office of Civil Rights (OCR) to make its Black colleges comparable with their White counterparts. While Maryland claims that it has satisfied its agreement with OCR, findings of this study challenge this assertion. Data from AAUP, University System of Maryland [USM], and the Morgan State Office of Institutional research show significant disparities in faculty salaries and workload between historically Black and predominantly White colleges in the state.

Geomorphic characteristics have been used as scaling parameters to predict water and other fluxes in many systems. In this study, we combined geomorphic analysis with in-situ mass balance studies of nitrate retention (NR) to evaluate which geomorphic scaling parameters best predicted NR in a tidal freshwater wetland ecosystem. Geomorphic characteristics were measured for 267 individual marshes that constitute the freshwater tidal wetland ecosystem of the Patuxent River, Maryland. Nitrate retention was determined from mass balance measurements conducted at the inlets of marshes of varying size (671, 5705, and 536 873m²) over a period of several years. Mass balance measurements indicate that NR is proportional to total water flux over the tidal cycle. Relationships between estimated tidal prism (total water volume) for spring tides and various geomorphic parameters (marsh area, total channel length, and inlet width) were defined and compared to field data. From these data, NR equations were determined for each geomorphic parameter, and used to estimate NR for all marshes in the ecosystem for a reference spring (high) tide. The resulting ecosystem NR estimates were evaluated for: (a) accuracy and completeness of geomorphic data, b) relationship between the geomorphic parameters and hydrologic flux, and (c) the ability to adapt the geomorphic parameter to varying tidal conditions. This analysis indicated that inlet width data were the most complete and provided the best estimate of ecosystem nitrate retention. Predictions based on marsh area were significantly lower than the inlet width-based predictions. Cumulative probability distributions of nitrate retention indicate that the largest 3-4% of the marshes retained half of the total nitrate for the ecosystem. [ABSTRACT FROM AUTHOR]

This paper shares four Sea Grant-funded projects from across the United States. The Hawai'i project integrates Western science and Hawaiian culture in placeand community-based teaching. The Maryland program takes a project-based learning approach to aquaculture education in the formal education system. The Massachusetts (MIT) project focuses on state-of-the-art technology in engineering, robotics, and ocean science. The Virginia project emphasizes science communication and lesson plan design. What all four projects have in common is their focus on environmental literacy and teacher professional development in formal education. This approach aims to raise the quality of STEM instruction by expanding teachers' knowledge, skills, and resources. Training teachers also efficiently utilizes resources by maximizing the number of students we ultimately reach, thereby creating sustainability. [ABSTRACT FROM AUTHOR]

This paper discusses the chemistry manuscript collection in an institution that does not readily come to mind when searching for unpublished matter on the history of chemistry, the National Library of Medicine in Bethesda, Maryland. This collection includes personal papers of some twentieth-century American chemists and biochemists, lecture notes of British and American chemistry courses of the eighteenth, nineteenth, and twentieth centuries from a variety of institutional settings, and extended oral histories of some major figures in the history of modern chemistry and biochemistry. Among those represented in this collection are Joseph Black, Louis Pasteur, George B. Wood, Donald D. Van Slyke, and Albert Szent-Györgyi. In addition to illustrating the type of resources available, this paper also suggests some specific ways in which the collection can contribute to research in the history of chemistry.

The balance between organic matter production and decay determines how fast coastal wetlands accumulate soil organic matter. Despite the importance of soil organic matter accumulation rates in influencing marsh elevation and resistance to sea-level rise, relatively little is known about how decomposition rates will respond to sea-level rise. Here, we estimate the sensitivity of decomposition to flooding by measuring rates of decay in 87 bags filled with milled sedge peat, including soil organic matter, roots and rhizomes. Experiments were located in field-based mesocosms along 3 mesohaline tributaries of the Chesapeake Bay. Mesocosm elevations were manipulated to influence the duration of tidal inundation. Although we found no significant influence of inundation on decay rate when bags from all study sites were analyzed together, decay rates at two of the sites increased with greater flooding. These findings suggest that flooding may enhance organic matter decay rates even in water-logged soils, but that the overall influence of flooding is minor. Our experiments suggest that sea-level rise will not accelerate rates of peat accumulation by slowing the rate of soil organic matter decay. Consequently, marshes will require enhanced organic matter productivity or mineral sediment deposition to survive accelerating sea-level rise. [ABSTRACT FROM AUTHOR]

The 15th ACM SIGPLAN International Conference on Functional Programming (ICFP) took place on September 27–29, 2010 in Baltimore, Maryland. After the conference, the programme committee, chaired by Stephanie Weirich, selected several outstanding papers and invited their authors to submit to this special issue of Journal of Functional Programming. Umut A. Acar and James Cheney acted as editors for these submissions. This issue includes the seven accepted papers, each of which provides substantial new material beyond the original conference version. The selected papers reflect a consensus by the program committee that ICFP 2010 had a number of strong papers that link core functional programming ideas with other areas, such as multicore, embedded systems, and data compression.

Over the last few decades, more attention has been paid to the physician gender pay gap and more interventions have been attempted. This paper discusses the physician gender pay gap between 2017 and 2021 in Maryland. An online cross-sectional survey was distributed to over 10,000 physicians in the Maryland Medical Society, featuring questions regarding employment characteristics, compensation, impact of the COVID-19 pandemic, and educational debt. Using descriptive and regression analyses, we explored cross-sectional associations between gender and employment characteristics. Male physicians reported a significantly higher average 2020 pre-tax income ($333,732 per year) than female physicians ($225,473 per year, p < 0.001), amounting to a nearly 50% difference in raw income, consistent with a previously reported pay gap in 2016. Women physicians earned 31.5% less than their male colleagues in 2020 and were projected to earn 28.7% less in 2021. Female physicians were also more likely to have educational debt (33.6% vs.12.9%, p < 0.001) and also more likely to have a high burden of debt, with 36% owing over $200,000 in education loans, compared to 14.7% of men (p < 0.01). The physician gender pay gap in Maryland has remained relatively stable over four years, including the period of the COVID-19 pandemic. The physician gender pay gap in Maryland has remained stable over four years, including the period of the COVID-19 pandemic. Female physicians earned over 30% less than male physicians in Maryland in 2020. Female physicians are more likely to have educational debt, and when they do, they have a greater magnitude of debt.

This study uses machine learning methods to model different stages of the calcination process in cement, with the goal of improving knowledge of the generation of CO2 during cement manufacturing. Calcination is necessary to determine the clinker quality, energy needs, and CO2 emissions in a cement-producing facility. Due to the intricacy of the calcination process, it has historically been challenging to precisely anticipate the CO2 produced. The purpose of this study is to determine a direct association between CO2 generation from the manufacture of raw materials and the process factors. In this paper, six machine learning techniques are investigated to explore two output variables: (1) the apparent degree of oxidation, and (2) the apparent degree of calcination. CO2 molecular composition (dry basis) sensitivity analysis uses over 6000 historical manufacturing health data points as input variables, and the results are used to train the algorithms. The Root Mean Squared Error (RMSE) of various regression models is examined, and the models are then run to ascertain which independent variables in cement manufacturing had the largest impact on the dependent variables. To establish which independent variable has the biggest impact on CO2 emissions, the significance of the other factors is also assessed. [ABSTRACT FROM AUTHOR]

When designing a patrol route, it is often necessary to pay more attention to locations with high crime rates. In this paper, we study a patrol routing problem for a fleet of patrol cars patrolling a region with a high-crime neighborhood (HCN) consisting of multiple hot spots. Considering the disorder and chaos in the HCN, at least one patrol car is required in the HCN at any given time during the patrol. We call this routing problem the hot spot coverage patrol problem (HSCPP). In the HSCPP, the importance of a patrol location is quantified by a prize, and the prize is collected if a patrol car visits the location. Our objective is to maximize the sum of prizes collected by the patrol cars, obeying all operational requirements. We propose mathematical formulations and develop several solution approaches for the HSCPP. The global approach consists of finding the routing solution for all patrol cars with a single integer programming (IP) formulation. The partition approach involves first partitioning the region geographically and solving the routing problem in each subregion with two IP formulations. Next, we strengthen the partition approach by developing a column generation (CG) approach in which the initial columns of the CG approach are the solutions generated from the partition approach. We conduct a detailed computational case study using instances based on real crime data from Montgomery County, Maryland. To further understand the computational tractability of our solution approaches, we also perform a sensitivity analysis using synthetic instances under various scenarios.

Plastic debris in aquatic and marine environments often breaks up into fragments that are smaller than 5 millimeters, which are then classified as microplastics. While there is not yet a standardized and validated methodology for characterizing microplastics, the protocol developed in this study uses methods for isolating and observing microplastics and for the investigation of how they interact with organisms present in biofilms from urban waterways. Project-based learning (PBL) has been proven to be a successful strategy in K–12 science education; the implementation of PBL provides opportunities for student-driven inquiry and provides teachers with a means to integrate curriculum with current research and to consider the effects of human impacts on the environment. This paper describes the protocol developed for high school teachers to educate students about microplastics and how to successfully isolate and observe them. Teachers and students in Maryland successfully isolated microplastics from biofilm samples from the Inner Harbor, Baltimore, Maryland, and shared their results. International teachers and students in Barcelona, Spain, involved in a related project, had similar results and shared experiences through images, video, and online meetings. These collaborations provide important opportunities for student-driven inquiry and for them to engage in methods of current scientific research. [ABSTRACT FROM AUTHOR]

Social informatics' past, present and future were the focus of the 8th annual SIG/SI Research Symposium at the 2012 ASIS&T Annual Meeting, with presenters from Europe, Canada and the United States. Papers on the past of social informatics explored its roots in the early 1980s and its domain organization reflected through bibliometric analysis. Current research topics described the influence of information and communication technologies as a contextual element that shapes experience and social interaction, knowledge sharing across boundaries in online communities and studying subjectivity in Web 2.0 research collaborations through Q methodology. Presenters considered the future of social informatics in terms of the influence of information and communication technologies on the economic order, aspects of information practice that demand attention and topics and frameworks for further research. Best paper awards were given for studies on evolving digital rights and urban immigrants' information tactics. Through the symposium and interaction with other SIGs, researchers were encouraged to take a broad view of social informatics to better understand its lessons, influences and future directions.

This paper aims at analyzing Maryland Governor Thomas H. Hicks's role in the contentious political environment during the Civil War. Using a combination of secondary and primary resources, including letters from the Pennsylvania and North Carolina legislatures, Hick's speeches, transcripts from the Maryland Assembly, and books on Maryland State History, this paper begins by substantiating Maryland's vulnerable position as a border state during the Civil War. Additionally, the paper will illustrate the pressures facing Hicks as he made the decision to allow open debate despite tense political opposition over slavery. Through an in-depth examination, this paper will provide a context for Hick's decision and highlight his support of individual rights, freedom of speech, and democracy during a critical moment when Maryland was faced with the choice to join the Union or secede.

Nonpoint source (NPS) pollution is a severe problem in the U.S. and worldwide. Best management practices (BMPs) have been widely used to control stormwater and reduce NPS pollution. Previous research has shown that socio-economic factors affect households' adoption of BMPs, but few studies have quantitatively analyzed the spatio-temporal dynamics of household BMP adoption under different socio-economic conditions. In this paper, diverse regression approaches (linear, LASSO, support vector, random forest) were used on the ten-year data of household BMP adoption in socio-economically diverse areas of Washington, D.C., to model BMP adoption behaviors. The model with the best performance (random forest regression, R2 = 0.67, PBIAS = 7.2) was used to simulate spatio-temporal patterns of household BMP adoption in two nearby watersheds (Watts Branch watershed between Washington, D.C., and Maryland; Watershed 263 in Baltimore), each of which are characterized by different socio-economic (population density, median household income, renter rate, average area per household, etc.) and physical attributes (total area, percentage of canopy in residential area, average distance to nearest BMPs, etc.). The BMP adoption rate was considerably higher at the Watts Branch watershed (14 BMPs per 1000 housing units) than at Watershed 263 (4 BMPs per 1000 housing units) due to distinct differences in the watershed characteristics (lower renter rate and poverty rate; higher median household income, education level, and canopy rate in residential areas). This research shows that adoption behavior tends to cluster in urban areas across socio-economic boundaries and that targeted, community-specific social interventions are needed to reach the NPS control goal.

This paper investigates the student perspective on Maryland's Early Childhood Education/Special Education Associate of Arts in Teaching (AAT) degree: the factors that affected their experience, especially with the transfer process, and whether their experiences differed by institution. Viewpoints were gathered through focus groups and individual interviews of 18 community college students in their final semester before transferring and in their first semester at a Maryland university to complete their BA and teaching certification. This study reports that participants had positive feedback about their programs but agreed on the need for more practical experience, especially regarding special education content. A clear concern about online coursework in Early Childhood Education was also expressed. Factors affecting the student experience included misadvising and confusion around transfer that continued after moving to university programs. Administrators and faculty also acknowledged a number of challenges associated with advising, programming and implementation. Students highlighted differences between institutions but noted that most issues could be resolved through better communication, collaboration, and coordination. This study is important to two-year programs working to improve retention and transfer, as well as universities working to support transfer students. Further research is needed beyond Maryland on the student experience and potential solutions. [ABSTRACT FROM AUTHOR]

This paper presents the mathematical modeling and optimal trajectory tracking control of a 3-degree-of-freedom parallel manipulator, commonly known as Maryland manipulator. Three unlike sequential trajectories are considered, and the trajectory-tracking control of a manipulator is performed by the LQR-PID controller. The tuning of LQR-PID is done by using the Grey Wolf Optimizer (GWO), a meta-heuristic method. The two other traditional benchmarking algorithms are Particle Swarm Optimizer (PSO) and Genetic Algorithm (GA). The main goal of this work is to calculate the optimum values of LQR gain parameters i.e. Q and R matrices and PID controller's gains i.e. Kp, Ki and Kd using three different optimization algorithms, and their performance comparisons are highlighted in simulation results and discussion section. According to the obtained simulation results, the proposed GWO methodology is more efficient and more accurate in trajectory tracking control and generates optimal torques to the input links of the manipulator when compared with other evolutionary optimization algorithms such as PSO and GA.

The hypothesis that minority voters act in their economic self-interest in supporting municipal candidates of their own race or ethnicity has been tested using changes in municipal spending and employment. However, governments affect voter welfare in many other ways, particularly in the provision of quality public services. This paper exploits a natural experiment arising in 1995 when Congress created an appointed financial control board for the District of Columbia and gave to it many of the powers previously reserved to the local elected government. The natural experiment sets up a triple-difference research design based on changes in property values across District neighborhoods and voting behavior compared to untreated adjacent areas across the District boundary in Maryland. We find that oversight by the control board raised annual appreciation rates in the District by 178 to 254 basis points during the period from 1995 to 2001. Furthermore, effects of the intervention were uniformly positive across areas of the District that varied dramatically in their support for the incumbent administration that lost its powers. This implies, after the fact, that the administration's supporters had not voted in accord with economic self-interest. [ABSTRACT FROM AUTHOR]

Wade Hampton Frost, who was a Professor of Epidemiology at Johns Hopkins University from 1919 to 1938, spurred the development of epidemiologic methods. His 6 publications in the American Journal of Hygiene, which later became the American Journal of Epidemiology, comprise a 1928 Cutter lecture on a theory of epidemics, a survey-based study of tonsillectomy and immunity to Corynebacterium diphtheriae (1931), 2 papers from a longitudinal study of the incidence of minor respiratory diseases (1933 and 1935), an attack rate ratio analysis of the decline of diphtheria in Baltimore (1936), and a 1936 lecture on the age, time, and cohort analysis of tuberculosis mortality. These 6 American Journal of Hygiene /American Journal of Epidemiology papers attest that Frost's personal evolution mirrored that of the emerging “early” epidemiology: The scope of epidemiology extended beyond the study of epidemics of acute infectious diseases, and rigorous comparative study designs and their associated quantitative methods came to light.

Background: Systems science approaches like simulation modeling can offer an opportunity for community voice to shape policies. In the episteme of many communities there are elders, leaders, and researchers who are seen as bearers of historic knowledge and can contextualize and interpret contemporary research using knowledge systems of the community. There is a need for a systematic methodology to collaborate with community Knowledge Bearers and Knowledge Interpreters. In this paper we report the results of piloting a systematic methodology for collaborating with a community Knowledge-Bearer and Knowledge-Interpreter to develop a conceptual model revealing the local-level influences and architecture of systems shaping community realities. The use case for this pilot is 'persistent poverty' in the United States, specifically within the inner-city African American community in Baltimore City. Methods: This pilot of a participatory modeling approach was conducted over a span of 7 sessions and included the following steps, each with an associated script: Step 1: Knowledge-Bearer and Knowledge-Interpreter recruitment Step 2: Relationship building Step 3: Session introduction, Vignette development & enrichment Step 4: Vignette analysis & constructing architecture of systems map Step 5: Augmenting architecture of systems map Results: Each step of the participatory modeling approach resulted in artifacts that were valuable for both the communities and the research effort. Vignette construction resulted in narratives representing a spectrum of lived experiences, trajectories, and outcomes within a community. The collaborative analysis of vignettes yielded the Architecture of Systemic Factors map, that revealed how factors inter-relate to form a system in which lived experience of poverty occurs. A literature search provided an opportunity for the community to contextualize existing research about them using realities of lived experience. Conclusion: This methodology showed that a community Knowledge Bearer can function as communicators and interpreters of their community's knowledge base, can develop coherent narratives of lived experiences within which research and knowledge is contextualized, and can collaboratively construct conceptual mappings necessary for simulation modeling. This participatory modeling approach showed that even if there already exists a vast body of research about a community, collaborating with community gives context to that research and brings together disparate findings within narratives of lived experience.

Group‐based parent‐training (PT) is one of the most common and well‐established approaches for strengthening parenting skills and reducing child behavior problems. When offered in school settings, the social connections formed among participants may generate additional benefits for parents, schools, and children. However, to date there has been limited research on the potential benefits or harms associated with social connectedness (SC) in group‐based PT. This paper describes the study protocol for an ongoing National Institute of Nursing Research‐funded mixed‐methods study that aims to examine the extent to which group‐based PT, delivered in elementary schools serving families from predominantly low‐resource communities, generates SC among parents and if SC is associated with greater (a) reduction in child behavior problems and (b) engagement in their child's education. Using a prospective descriptive design, the study is nested within an ongoing quasi‐experimental parent study evaluating the group‐based PT intervention, the Chicago Parent Program (CPP) in Baltimore City schools. Challenges for this study include recruitment and retention of parents with constraints caused by the COVID‐19 pandemic. The study uses multiple methods and informants to understand the potential mechanisms underlying PT group effects and results have the potential to serve as an important foundation for future studies focused on SC, its impacts on parent‐child outcomes in low‐resource settings, and strategies for strengthening SC in health promotion interventions. Patient or Public Contribution: Chicago Parent Program was developed with input from an advisory board of parents. Additionally, the parent study protocol was written and is co‐led in partnership with a community organization. [ABSTRACT FROM AUTHOR]

Background: Computerized provider order entry (CPOE) is being implemented at increasing numbers of U.S. hospitals, yet the effects of CPOE on medical student education are largely unstudied. Purpose: The objective is to investigate the effects of CPOE on medical students’ ability to write orders for patients. Methods: One hundred forty-three medical students who began their Basic Medicine clerkship between March 2003 and April 2004 were asked to write mock admission orders for a patient with pneumonia after the 1st month of their clerkship. Students had spent the month at 1 of 3 hospitals: 1 using CPOE, 1 paper orders, and 1 that began using CPOE midway through this study. Admission orders were scored for the presence of specific orders and features. Results: One hundred twenty students attempted to write admission orders. Students who trained at hospitals using CPOE and those who trained at hospitals using paper orders included expected basic, lifesaving, and higher level orders at similar rates. No significant differences in order clarity or inclusion of unnecessary orders were found for the 2 groups. No significant differences were found when controlling for school year and 4 modifiable rotation features. Conclusions: When admission order completeness and quality for medical students who trained at hospitals using CPOE were compared to those who trained using handwritten orders, no important differences were found.

Background: Scaling up continuous quality improvement (CQI) processes could be key in achieving the 95:95:95 cascade and global HIV targets. This paper describes the experiences and outcomes related to implementing CQI processes to help reach these targets, with particular focus on clinical and programmatic settings in 6 countries from the global south.Methods: The HIV program at the University of Maryland, Baltimore (UMB) implemented an adapted CQI model in Kenya, Tanzania, Botswana, Zambia, Nigeria and Rwanda that included the following steps: (1) analysing the problem to identify goals and objectives for improvement; (2) developing individual changes or 'change packages', (3) developing a monitoring system to measure improvements; and (4) implementing and measuring changes through continuous 'plan-do-study-act' (PDSA) cycles. We describe country-level experiences related to implementing this adaptive design, a collaborative learning and scale-up/sustainability model that addresses the 95:95:95 global HIV targets via a CQI learning network, and mechanisms for fostering communication and the sharing of ideas and results; we describe trends both before and after model implementation.Results: Our selected country-level experiences based on implementing our CQI approach resulted in an increased partner testing acceptance rate from 21.7 to 48.2 % in Rwanda, which resulted in an increase in the HIV testing yield from 2.1 to 6.3 %. In Botswana, the overall linkage to treatment improved from 63 to 94 %, while in Kenya, the viral load testing uptake among paediatric and adolescent patients improved from 65 to 96 %, and the viral load suppression improved from 53 to 88 %.Conclusions: Adopting CQI processes is a useful approach for accelerating progress towards the attainment of the global 95:95:95 HIV targets. This paper also highlights the value of institutionalizing CQI processes and building the capacity of Ministry of Health (MoH) personnel in sub-Saharan Africa for the effective quality improvement of HIV programs and subsequent sustainability efforts.

Background: While there is recognition by the greater medical community and physical therapists to address the biopsychosocial needs of people with chronic, persistent pain, there are challenges in implementation and delivery including wide variability in interventions, lack of clear rationale, and absence of clinical models that are feasible and acceptable on a large scale. Important components for psychologically informed physical therapy (PiPT) for pain care include behavioral approaches (e.g., Acceptance and Commitment Therapy), mindfulness, pain neuroscience education, motivational interviewing (MI), and interoceptive skills-building. The Empower Veterans Program (EVP) Mindful Movement framework blends these components and emphasizes a mindfulness and self-compassion approach with MI and body-based experiential learning. This program was offered in-person at the Atlanta and Maryland VA Health Care Centers with published positive Patient Reported Outcomes (PRO) pre-COVID 19 crisis and shifted to entirely remote delivery in March 2020. Objective: This paper offers an evidence-based and theory driven framework to operationalize a remotely delivered groupbased psychologically informed mindful movement physical therapy intervention as part of an interdisciplinary pain care program. Methods: Since 2021 PRO and demographics are collected using a survey administered through Qualtrics over a 12-month period at baseline, immediately post TelePain EVP, at 6 months, and at 12 months, with findings forthcoming. Discussion/Results: Tele-pain EVP offers 6-9 groups a week with 7-9 veterans from Atlanta based team and 3-4 groups a week with 5-9 veterans from Maryland based team. Adaptations for remote delivery optimized mindfulness and active learning strategies including interoceptive skills-building and use of MI to support self-efficacy to trust, restore a sense of safety in the body, and explore adaptations for safe movement. Conclusion: TelePain-EVP Mindful Movement provides a framework for other programs to translate for their populations and systems to further develop best practices in PiPT for pain care and integration into interdisciplinary care.
