the data assimilation research testbed a Community Facility
Bulletin of the American Meteorological Society, 2009Co-Authors: Jeffrey L Anderson, Timothy J Hoar, Kevin Raeder, Nancy Collins, Ryan D Torn, Avelino AvellanoAbstract:Abstract The Data Assimilation Research Testbed (DART) is an open-source Community Facility for data assimilation education, research, and development. DART's ensemble data assimilation algorithms, careful software engineering, and diagnostic tools allow atmospheric scientists, oceanographers, hydrologists, chemists, and other geophysicists to build state-of-the-art data assimilation systems with unprecedented ease. For global numerical weather prediction, DART produces ensemble-mean analyses comparable to analyses from major centers while also providing initial conditions for ensemble predictions. In addition, DART supports more novel assimilation applications like parameter estimation, sensitivity analysis, observing system design, and smoothing. Implementing basic systems for large models requires only a few person-weeks; comprehensive systems have been built in a few months. Incorporating new observation types is also straightforward, requiring only a forward operator mapping between a model's state a...

DART/CAM: An Ensemble Data Assimilation System for CESM Atmospheric Models
Journal of Climate, 2012Co-Authors: Kevin Raeder, Jeffrey L Anderson, Timothy J Hoar, Nancy Collins, Peter H. Lauritzen, Robert PincusAbstract:AbstractThe Community Atmosphere Model (CAM) has been interfaced to the Data Assimilation Research Testbed (DART), a Community Facility for ensemble data assimilation. This provides a large set of data assimilation tools for climate model research and development. Aspects of the interface to the Community Earth System Model (CESM) software are discussed and a variety of applications are illustrated, ranging from model development to the production of long series of analyses. CAM output is compared directly to real observations from platforms ranging from radiosondes to global positioning system satellites. Such comparisons use the temporally and spatially heterogeneous analysis error estimates available from the ensemble to provide very specific forecast quality evaluations. The ability to start forecasts from analyses, which were generated by CAM on its native grid and have no foreign model bias, contributed to the detection of a code error involving Arctic sea ice and cloud cover. The potential of param...

The inclusion of palliative care in initial treatment planning for women with gynecologic cancer and the use of advanced directives.
Journal of Clinical Oncology, 2016Co-Authors: Rachel Regn, William H. Robinson, William R. RobinsonAbstract:23 Background: To determine differences in Advanced Directive (AD) utilization among women with gynecologic cancer at a Facility with a functioning Palliative Care (PC) program, vs those in a Facility without access to a PC program. Also, to identify possible ethnic differences or relationships to other PC needs to AD utilization. Methods: 95 subjects with gynecologic cancer were prospectively identified, 30 from an inner-city academic Facility (Site A), and 65 from a suburban Community Facility in the same metropolitan area. (Site B) All patients received treatment from board-certified oncologists. All subjects were approached by Master’s trained Social Workers at presentation with a diagnosis of cancer and asked to complete a standardized, validated questionnaire (modified Distress Thermometer (DT)) to determine their palliative care needs and whether they had an AD prior to treatment (baseline), and 6 months later. Completed questionnaires were collected and data was depersonalized and analyzed by the ...

Differences in palliative care needs among women with gynecologic cancers in an inner city, academic Facility versus a suburban, Community Facility
Gynecologic Oncology, 2014Co-Authors: William R. RobinsonAbstract:Objectives: The aim of this study was to determine differences in palliative care needs inwomenwith gynecologic cancers from anurban, inner city, academic Facility compared to a suburban, Community Facility and also, to identify interventions that could improve palliative care for gynecologic cancer patients in varying locations. Methods: 71 women with gynecologic cancer were prospectively identified, 54 from an urban, inner city academic cancer center, and 17 from a suburban Community cancer center in the same metropolitan area. All subjects were asked to complete a standardized, validated questionnaire intended to determine their palliative care needs after diagnosis but prior to treatment. Palliative care trained, Master's level social workers introduced themselves and the questionnaire to patients, and offered to help with additional needs. Completed questionnaires were collected and appropriate data was extracted. The data was depersonalized and analyzed by the authors. Statistical differences were assessed with SigmaStat V.2.0. Results: All patients were treated by board-certified gyn oncologists. The types of cancers seen and treatments offered (all of which met NCCN guidelines) were similar. Inner city academic patients were less likely to complete the questionnaire than the suburban Community patients (64% vs 100% of those offered, p b 0.001). Patients from the inner city academic group were younger (54 years old vs 61 years old, p b 0.05) and more likely to be African–American (77% vs 29%, p b 0.05) than those from the suburban Community group. The ratio of Medicaid to private/Medicare insurance coverage was higher in inner city academic patients than suburban Community patients (58% vs 22%, p b 0.05). The most common palliative care concerns identified by suburban Community patientswere: 1) pain, 2) anxiety, 3) depression, 4) nausea/vomiting. In comparison, the most common concerns identified by inner city academic patients were: 1) paying for medications, 2) travel to the treatment Facility, 3) pain, and 4) child care. Conclusion: There are major differences in the palliative care needs of patients from an inner city academic Facility compared to a suburban Community Facility. Interventions proposed for the suburban Community Facility were early access to: 1) grief counseling, 2) patient support groups, and 3) Nurse–Navigator services. Interventions proposed for the inner city academic Facility include early access to: 1) programs for assistance with medication costs (local philanthropies, Facility-based pharmacy discounts), 2) travel services (cab vouchers, coordination of treatments with public transportation schedules), and 3) on-site child care facilities. Further, inner city academic patients should be encouraged to voice their palliative care concerns. More specific determinations of patient concerns are needed to help structure palliative care services in different types of facilities.

Community Facility and individual level outcomes of a district mental healthcare plan in a low resource setting in nepal a population based evaluation
PLOS Medicine, 2019Co-Authors: Mark J D Jordans, Nagendra P Luitel, Brandon A Kohrt, Sujit D Rathod, Emily C Garman, Mary De Silva, Ivan H Komproe, Vikram PatelAbstract:BACKGROUND: In low-income countries, care for people with mental, neurological, and substance use (MNS) disorders is largely absent, especially in rural settings. To increase treatment coverage, integration of mental health services into Community and primary healthcare settings is recommended. While this strategy is being rolled out globally, rigorous evaluation of outcomes at each stage of the service delivery pathway from detection to treatment initiation to individual outcomes of care has been missing. METHODS AND FINDINGS: A combination of methods were employed to evaluate the impact of a district mental healthcare plan for depression, psychosis, alcohol use disorder (AUD), and epilepsy as part of the Programme for Improving Mental Health Care (PRIME) in Chitwan District, Nepal. We evaluated 4 components of the service delivery pathway: (1) contact coverage of primary care mental health services, evaluated through a Community study (N = 3,482 combined for all waves of Community surveys) and through service utilisation data (N = 727); (2) detection of mental illness among participants presenting in primary care facilities, evaluated through a Facility study (N = 3,627 combined for all waves of Facility surveys); (3) initiation of minimally adequate treatment after diagnosis, evaluated through the same Facility study; and (4) treatment outcomes of patients receiving primary-care-based mental health services, evaluated through cohort studies (total N = 449 depression, N = 137; AUD, N = 175; psychosis, N = 95; epilepsy, N = 42). The lack of structured diagnostic assessments (instead of screening tools), the relatively small sample size for some study components, and the uncontrolled nature of the study are among the limitations to be noted. All data collection took place between 15 January 2013 and 15 February 2017. Contact coverage increased 7.5% for AUD (from 0% at baseline), 12.2% for depression (from 0%), 11.7% for epilepsy (from 1.3%), and 50.2% for psychosis (from 3.2%) when using service utilisation data over 12 months; Community survey results did not reveal significant changes over time. Health worker detection of depression increased by 15.7% (from 8.9% to 24.6%) 6 months after training, and 10.3% (from 8.9% to 19.2%) 24 months after training; for AUD the increase was 58.9% (from 1.1% to 60.0%) and 11.0% (from 1.1% to 12.1%) for 6 months and 24 months, respectively. Provision of minimally adequate treatment subsequent to diagnosis for depression was 93.9% at 6 months and 66.7% at 24 months; for AUD these values were 95.1% and 75.0%, respectively. Changes in treatment outcomes demonstrated small to moderate effect sizes (9.7-point reduction [d = 0.34] in AUD symptoms, 6.4-point reduction [d = 0.43] in psychosis symptoms, 7.2-point reduction [d = 0.58] in depression symptoms) at 12 months post-treatment. CONCLUSIONS: These combined results make a promising case for the feasibility and impact of Community- and primary-care-based services delivered through an integrated district mental healthcare plan in reducing the treatment gap and increasing effective coverage for MNS disorders. While the integrated mental healthcare approach does lead to apparent benefits in most of the outcome metrics, there are still significant areas that require further attention (e.g., no change in Community-level contact coverage, attrition in AUD detection rates over time, and relatively low detection rates for depression).

Waste to Energy Solution - The Sludge Treatment Facility in Tuen Mun, Hong Kong
Energy Procedia, 2017Co-Authors: Leslie Swann, David Downs, Melissa WayeAbstract:The Environmental Protection Department (EPD) of the Government of Hong Kong Special Administrative Region is the owner and project proponent of the Sludge Treatment Facility (STF), a Facility dedicated to treating sewage sludge. The Contract to design, build and operate the STF was awarded to VW-VES (HK) Limited (a subsidiary of Veolia), and Jacobs China Limited was appointed to act as the Employer's Representative in October 2010. The construction of the STF was substantially completed in 2015 and it was put into operation on 1 April 2015. The STF, featuring state-of-art incineration technology, provides for a sustainable sewage sludge treatment solution, with a view to maximizing the reduction on disposal of the sludge to landfill. In consideration of the diminishing landfill space, the STF is designed to have a capacity of treating 2,000 tonnes per day, thereby reducing the mass of the sludge by 90%. The STF is also on another green mission - to convert waste into renewable energy harnessing the heat from the incineration process to generate electricity, resulting in the provision of all power for the daily on-site operations, with the design allowing the export of surplus power to the local grid. The STF also includes facilities for the production of both process and potable water as well as being able to treat all waste water for use on-site. This adopted design makes the STF a self-sustainable Facility with no incoming water supply and outfall for wastewater. As well as the abovementioned technical aspects, the STF serves as a Community Facility. An environmental education centre located inside the STF showcases the technology used within the STF to convert waste-to-energy, and also to promote public awareness of various environmental issues in Hong Kong. There is also a diverse range of recreational and open areas (e.g. spa and garden) for the public to experience the benefits of waste-to-energy. Since the opening of the EEC on 29 June 2016, the number of visitors has exceeded 72,000.
