    2014-01-01

    In communication-and-resolution programs (CRPs), health systems and liability insurers encourage the disclosure of unanticipated care outcomes to affected patients and proactively seek resolutions, including offering an apology, an explanation, and, where appropriate, reimbursement or compensation. Anecdotal reports from the University of Michigan Health System and other early adopters of CRPs suggest that these programs can substantially reduce liability costs and improve patient safety. But little is known about how these early programs achieved success. We studied six CRPs to identify the major challenges in and lessons learned from implementing these initiatives. The CRP participants we interviewed identified several factors that contributed to their programs' success, including the presence of a strong institutional champion, investing in building and marketing the program to skeptical clinicians, and making it clear that the results of such transformative change will take time. Many of the early CRP adopters we interviewed expressed support for broader experimentation with these programs even in settings that differ from their own, such as systems that do not own and control their liability insurer, and in states without strong tort reforms.

    2013-01-01

    The adoption of virtual microscopy at the University of Turku, Finland, created a unique real-world laboratory for exploring ways of reforming the learning environment. The purpose of this study was to evaluate the students' reactions and the impact of a set of measures designed to boost an experimental group's understanding of abnormal histology through an emphasis on knowledge of normal cells and tissues. The set of measures included (1) digital resources to review normal structures and an entrance examination for enforcement, (2) digital course slides highlighting normal and abnormal tissues, and (3) self-diagnostic quizzes. The performance of historical controls was used as a baseline, as previous students had never been exposed to the above-mentioned measures. The students' understanding of normal histology was assessed in the beginning of the module to determine the impact of the first set of measures, whereas that of abnormal histology was assessed at the end of the module to determine the impact of the whole set of measures. The students' reactions to the instructional measures were assessed by course evaluation data. Additionally, four students were interviewed. Results confirmed that the experimental group significantly outperformed the historical controls in understanding normal histology. The students held favorable opinions on the idea of emphasizing normal structures. However, with regards to abnormal histology, the historical controls outperformed the experimental group. In conclusion, allowing students access to high-quality digitized materials and boosting prerequisite skills are clearly not sufficient to boost final competence. Instead, the solution may lie in making students externally accountable for their learning throughout their training. Anat Sci Educ 6: 73–80. © 2012 American Association of Anatomists. PMID:22930425

    2015-11-01

    Communities across the United States are increasingly tackling the complex task of changing their local environments and cultures to improve access to and consumption of healthy food. Communities that have received the Robert Wood Johnson Foundation Culture of Health Prize have deployed numerous evidence-informed strategies to enhance their local food environments. Their experiences can provide lessons for other communities working to improve health. In this article we examine how the prize-winning communities worked in a multidisciplinary collective manner to implement evidence-based strategies, deployed suites of strategies to expand the reach of food-related work, balanced evidence against innovation, and measured their own progress. Most of the communities also faced challenges in using evidence effectively to implement strategies to promote healthy food environments. Policy makers can accelerate the adoption of evidence-informed approaches related to food and health by embedding them in program standards and funding requirements. Establishing opportunities for ongoing training to enhance community practitioners' evaluation skills and collaborative leadership would also improve the effectiveness of community implementation of these strategies.

    2015-09-01

    Most surgeons recommend cleft palate repair between 6 and 12 months of age. Internationally adopted patients often undergo delayed repair due to social circumstances. There are few outcomes studies on this population. We conducted a 13-year retrospective review of all patients undergoing primary cleft palate repair at a single tertiary-care academic medical center between 1993 and 2006. The primary outcome was velopharyngeal insufficiency, defined as the recommendation for corrective surgery after multiple formal speech assessments. Two hundred one patients (102 males and 99 females) were identified. One hundred eighty-three repairs were performed before 18 months of age (standard repair group). Eighteen repairs were performed after 18 months of age (delayed repair group), with international adoption being a circumstance in 16 cases. The delayed and standard repair groups were similar with regard to sex, presence of craniofacial syndrome, Veau class, cleft size and laterality, type of repair, and operating surgeon. Mean follow-up was 9.3 years, with minimum follow-up of 5.0 years. Six (33%) of 18 patients in the delayed repair group developed velopharyngeal insufficiency compared to 23 (13%) of 183 in the standard repair group (P = 0.03 by Fisher exact test). These data demonstrate that internationally adopted patients undergoing delayed palate repair suffer especially poor speech outcomes. Physiologic differences in patients undergoing late repair, as well as social factors including adaptation to a new language and culture, may be factors. Early repair should be performed when possible. PMID:25046662

    The public health nurses’ scope of practice explicitly includes child protection within their role, which places them in a prime position to identify child protection concerns. This role compliments that of other professions and voluntary agenices who work with children. Public health nurses are in a privileged position as they form a relationship with the child’s parent(s)/guardian(s) and are able to see the child in its own environment, which many professionals cannot. Child protection in Ireland, while influenced by other countries, has progressed through a distinct pathway that streamlined protocols and procedures. However, despite the above serious failures have occurred in the Irish system, and inquiries over the past 20 years persistently present similar contributing factors, namely, the lack of standardized and comprehensive service responses. Moreover, poor practice is compounded by the lack of recognition of the various interactional processes taking place within and between the different agencies of child protection, leading to psychological barriers in communication. This article will explore the lessons learned for public health nurses practice in safeguarding children in the Republic of Ireland. PMID:27335944

    Despite evidence on what works in healthcare, there is a significant gap in the time it takes to bring research into practice. The Council of Academic Hospitals of Ontario's Adopting Research to Improve Care program addresses this research-to-practice gap by incorporating the following components into its funding program: strategic selection of evidence for implementation, education and training for implementation, implementation supports, executive champions and governance, and evaluation. Funded projects have been sustained (76% reported full sustainability) and spread to over 200 new sites. Lessons learned include the following: assess readiness, develop tailored implementation materials, consider characteristics of implementation supports, protect champion time and consider evaluation feasibility.

    The use of lessons learned as a tool for learning from past experiences is well established, especially by many organizations within the nuclear industry. Every person has, at some time, used the principles of lessons learned to adopt good work practices based on their own experiences or the experiences of others. Lessons learned can also help to avoid the recurrence of adverse practices, which is often an area that most lessons-learned programs tend to focus on. This paper will discuss how lessons learned relate to packaging and transportation issues and events experienced at Department of Energy (DOE) facilities. It will also discuss the role performed by the Office of Nuclear and Facility Safety`s Office of Operating Experience Analysis and Feedback in disseminating lessons learned and operating experience feedback to the DOE complex. The central concept of lessons learned is that any organization should be able to learn from its own experiences and events. In addition, organizations should implement methodologies to scan external environments for lessons learned, to analyze and determine the relevance of lessons learned, and to bring about the necessary changes learned from these experiences. With increased concerns toward facility safety, the importance of utilizing the lessons-learned principles and the establishment of lessons-learned programs can not be overstated.

    LLNL turned in 5 Declaration Line Items (DLI's) in 2006. Of these, one was declared completed. We made some changes to streamline our process from 2005, used less money, time and fewer team members. This report is a description of what changes we made in 2006 and what we learned. Many of our core review team had changed from last year, including our Laboratory Director, the Facility safety and security representatives, our Division Leader, and the OPSEC Committee Chair. We were able to hand out an AP Manual to some of them, and briefed all newcomers to the AP process. We first went to the OPSEC Committee and explained what the Additional Protocol process would be for 2006 and solicited their help in locating declarable projects. We utilized the 'three questions' from the AP meeting last year. LLNL has no single place to locate all projects at the laboratory. We talked to Resource Managers and key Managers in the Energy and Environment Directorate and in the Nonproliferation Homeland and International Security Directorate to find applicable projects. We also talked to the Principal Investigators who had projects last year. We reviewed a list of CRADA's and LDRD projects given to us by the Laboratory Site Office. Talking to the PI's proved difficult because of vacation or travel schedules. We were never able to locate one PI in town. Fortunately, collateral information allowed us to screen out his project. We had no problems in downloading new versions of the DWA and DDA. It was helpful for both Steve Blair and Arden Dougan to have write privileges. During the time we were working on the project, we had to tag-team the work to allow for travel and vacation schedules. We had some difficulty locating an 'activities block' in the software. This was mentioned as something we needed to fix from our 2005 declaration. Evidently the Activities Block has been removed from the current version of the software. We also had trouble finding the DLI Detail Report, which we included

  2. Barriers to the Adoption of Safety-Engineered Needles Following a Regulatory Standard: Lessons Learned from Three Acute Care Hospitals

    PubMed Central

    Chambers, Andrea; Mustard, Cameron A.; Holness, D. Linn; Nichol, Kathryn; Breslin, F. Curtis

    2015-01-01

    Background: A number of jurisdictions have introduced regulation to accelerate the adoption of safety-engineered needles (SENs). This study examined the transition to SENs in three acute care hospitals prior to and following the implementation of a regulatory standard in Ontario. This paper focuses on the ongoing barriers to the prevention of needlestick injuries among healthcare workers. Methods: Information from document review and 30 informant interviews were used to prepare three case studies detailing each organization's implementation activities and outcomes. Results: All three hospitals responded to the regulatory requirements with integrity and needlestick injuries declined. However, needlestick injuries continued to occur during the activation of safety devices, during procedures and during instrument disposal. The study documented substantial barriers to further progress in needlestick injury prevention. Conclusions: Healthcare organizations should focus on understanding their site-specific challenges that contribute to ongoing injury risk to better understand issues related to product limitations, practice constraints and the work environment.

    Objectives Eight grant teams used Agency for Healthcare Research and Quality infrastructure development research grants to enhance the clinical content of and improve race/ethnicity identifiers in statewide all-payer hospital administrative databases. Principal Findings Grantees faced common challenges, including recruiting data partners and ensuring their continued effective participation, acquiring and validating the accuracy and utility of new data elements, and linking data from multiple sources to create internally consistent enhanced administrative databases. Successful strategies to overcome these challenges included aggressively engaging with providers of critical sources of data, emphasizing potential benefits to participants, revising requirements to lessen burdens associated with participation, maintaining continuous communication with participants, being flexible when responding to participants’ difficulties in meeting program requirements, and paying scrupulous attention to preparing data specifications and creating and implementing protocols for data auditing, validation, cleaning, editing, and linking. In addition to common challenges, grantees also had to contend with unique challenges from local environmental factors that shaped the strategies they adopted. Conclusions The creation of enhanced administrative databases to support comparative effectiveness research is difficult, particularly in the face of numerous challenges with recruiting data partners such as competing demands on information technology resources. Excellent communication, flexibility, and attention to detail are essential ingredients in accomplishing this task. Additional research is needed to develop strategies for maintaining these databases when initial funding is exhausted. PMID:26119470

    An Agency team collaboration pilot was conducted from July 2002 until June 2003 and then extended for an additional year. The objective of the pilot was to assess the value of collaboration tools and adoption processes as applied to NASA teams. In an effort to share knowledge and experiences, the lessons that have been learned thus far are documented in this report. Overall, the pilot has been successful. An entire system has been piloted - tools, adoption, and support. The pilot consisted of two collaboration tools, a team space and a virtual team meeting capability. Of the two tools that were evaluated, the team meeting tool has been more widely accepted. Though the team space tool has been met with a lesser degree of acceptance, the need for such a tool in the NASA environment has been evidenced. Both adoption techniques and support were carefully developed and implemented in a way that has been well received by the pilot participant community.

    Global geodesy has improved dramatically over the past decade starting with the GPS for IERS and Geodynamics demonstration campaign in 1991 (GIG 91). At the time it took over a week of CPU time to process a network solution based on 21 global receivers and orbit overlaps were in the 40 cm range. Today it is possible to process a network solution based on 80 global receivers in less then one day of CPU time and orbit overlaps are in the 4 cm range. Special methods are under development for efficient processing of increasingly large regional networks which may contain hundreds or thousands of GPS receivers. Along the way there have been many lessons learned about GPS satellites, receivers, monuments, antennas, radomes, analysis, reference frames, error sources, and interpretation. A wide range of scientific disciplines have been impacted including studies of plate motion, post-glacial rebound, seasonal loading, deformation in plate boundary zones, coseismic displacements due to major earthquakes, postseiemic relaxation, and interseismic strain accumulation related to assessment of seismic hazards. Lessons learned will be presented in the context of new dense networks such as the Plate Boundary Observation (PBO).

Their range of applications include the formation of synthetic aperture radars for Earth sensing systems, large aperture observatories for next generation telescopes and the collection of spatially distributed measurements of time varying systems, probing the Earths magnetosphere, Earth-Sun interactions and the Earths geopotential. EDSN is a swarm of eight 1.5U Cubesats with crosslink, downlink and science collection capabilities developed by the NASA Ames Research Center under the Small Spacecraft Technology Program (SSTP) within the NASA Space Technology Mission Directorate (STMD). This paper describes the concept of operations of the mission and planned scientific measurements. The development of the 8 satellites for EDSN necessitated the fabrication of prototypes, Flatsats and a total of 16 satellites to support the concurrent engineering and rapid development. This paper has a specific focus on the development, integration and testing of a large number of units including the lessons learned throughout the project development.

  18. Constellation Program Lessons Learned. Volume 2; Detailed Lessons Learned

    These lessons learned are part of a suite of hardware, software, test results, designs, knowledge base, and documentation that comprises the legacy of the Constellation Program. The context, summary information, and lessons learned are presented in a factual format, as known and described at the time. While our opinions might be discernable in the context, we have avoided all but factually sustainable statements. Statements should not be viewed as being either positive or negative; their value lies in what we did and what we learned that is worthy of passing on. The lessons include both "dos" and "don ts." In many cases, one person s "do" can be viewed as another person s "don t"; therefore, we have attempted to capture both perspectives when applicable and useful. While Volume I summarizes the views of those who managed the program, this Volume II encompasses the views at the working level, describing how the program challenges manifested in day-to-day activities. Here we see themes that were perhaps hinted at, but not completely addressed, in Volume I: unintended consequences of policies that worked well at higher levels but lacked proper implementation at the working level; long-term effects of the "generation gap" in human space flight development, the need to demonstrate early successes at the expense of thorough planning, and the consequences of problems and challenges not yet addressed because other problems and challenges were more immediate or manifest. Not all lessons learned have the benefit of being operationally vetted, since the program was cancelled shortly after Preliminary Design Review. We avoid making statements about operational consequences (with the exception of testing and test flights that did occur), but we do attempt to provide insight into how operational thinking influenced design and testing. The lessons have been formatted with a description, along with supporting information, a succinct statement of the lesson learned, and

    The Hydrogen Incident Reporting and Lessons Learned website (www.h2incidents.org) was launched in 2006 as a database-driven resource for sharing lessons learned from hydrogen-related safety events to raise safety awareness and encourage knowledge-sharing. The development of this database, its first uses and subsequent enhancements have been described at the Second and Third International Conferences on Hydrogen Safety. [1,2] Since 2009, continuing work has not only highlighted the value of safety lessons learned, but enhanced how the database provides access to another safety knowledge tool, Hydrogen Safety Best Practices (http://h2bestpractices.org). Collaborations with the International Energy Agency (IEA) Hydrogen Implementing Agreement (HIA) Task 19 – Hydrogen Safety and others have enabled the database to capture safety event learnings from around the world. This paper updates recent progress, highlights the new “Lessons Learned Corner” as one means for knowledge-sharing and examines the broader potential for collecting, analyzing and using safety event information.

    As manned space exploration takes on the task of traveling beyond low Earth orbit, many problems arise that must be solved in order to make the journey possible. One major task is protecting humans from the harsh space environment. The current method of protecting astronauts during Extravehicular Activity (EVA) is through use of the specially designed Extravehicular Mobility Unit (EMU). As more rigorous EVA conditions need to be endured at new destinations, the suit will need to be tailored and improved in order to accommodate the astronaut. The Objective behind the EMU Lessons Learned Database(LLD) is to be able to create a tool which will assist in the development of next-generation EMUs, along with maintenance and improvement of the current EMU, by compiling data from Failure Investigation and Analysis Reports (FIARs) which have information on past suit failures. FIARs use a system of codes that give more information on the aspects of the failure, but if one is unfamiliar with the EMU they will be unable to decipher the information. A goal of the EMU LLD is to not only compile the information, but to present it in a user-friendly, organized, searchable database accessible to all familiarity levels with the EMU; both newcomers and veterans alike. The EMU LLD originally started as an Excel database, which allowed easy navigation and analysis of the data through pivot charts. Creating an entry requires access to the Problem Reporting And Corrective Action database (PRACA), which contains the original FIAR data for all hardware. FIAR data are then transferred to, defined, and formatted in the LLD. Work is being done to create a web-based version of the LLD in order to increase accessibility to all of Johnson Space Center (JSC), which includes converting entries from Excel to the HTML format. FIARs related to the EMU have been completed in the Excel version, and now focus has shifted to expanding FIAR data in the LLD to include EVA tools and support hardware such as

    Lessons Learned have been the basis for our accomplishments throughout the ages. They have been passed down from father to son, mother to daughter, teacher to pupil, and older to younger worker. Lessons Learned have also been the basis for the nation s accomplishments for more than 200 years. Both government and industry have long recognized the need to systematically document and utilize the knowledge gained from past experiences in order to avoid the repetition of failures and mishaps. Through the knowledge captured and recorded in Lessons Learned from more than 80 years of flight in the Earth s atmosphere, NASA s materials researchers are constantly working to develop stronger, lighter, and more durable materials that can withstand the challenges of space. The Agency s talented materials engineers and scientists continue to build on that rich tradition by using the knowledge and wisdom gained from past experiences to create futuristic materials and technologies that will be used in the next generation of advanced spacecraft and satellites that may one day enable mankind to land men on another planet or explore our nearest star. These same materials may also have application here on Earth to make commercial aircraft more economical to build and fly. With the explosion in technical accomplishments over the last decade, the ability to capture knowledge and have the capability to rapidly communicate this knowledge at lightning speed throughout an organization like NASA has become critical. Use of Lessons Learned is a principal component of an organizational culture committed to continuous improvement.

    Systems Engineering is fundamental to good engineering, which in turn depends on the integration and application of engineering lessons learned. Thus, good Systems Engineering also depends on systems engineering lessons learned from within the aerospace industry being documented and applied. About ten percent of the engineering lessons learned documented in the NASA Lessons Learned Information System are directly related to Systems Engineering. A key issue associated with lessons learned datasets is the communication and incorporation of this information into engineering processes. As part of the NASA Technical Standards Program activities, engineering lessons learned datasets have been identified from a number of sources. These are being searched and screened for those having a relation to Technical Standards. This paper will address some of these Systems Engineering Lessons Learned and how they are being related to Technical Standards within the NASA Technical Standards Program, including linking to the Agency's Interactive Engineering Discipline Training Courses and the life cycle for a flight vehicle development program.

    This Paper reports lessons learned and state of knowledge gained from an organizational factors research activity involving commercial nuclear power plants in the United States, through the end of 1991, as seen by the scientists immediately involved in the research. Lessons learned information was gathered from the research teams and individuals using a question and answer format. The following five questions were submitted to each team and individual: (1) What organizational factors appear to influence safety performance in some systematic way, (2) Should organizational factors research focus at the plant level, or should it extend beyond the plant level to the parent company, rate setting commissions, regulatory agencies, (3) How important is having direct access to plants for doing organizational factors research, (4) What lessons have been learned to date as the result of doing organizational factors research in a nuclear regulatory setting, and (5) What organizational research topics and issues should be pursued in the future? Conclusions based on the responses provided for this report are that organizational factors research can be conducted in a regulatory setting and produce useful results. Technologies pioneered in other academic, commercial, and military settings can be adopted for use in a nuclear regulatory setting. The future success of such research depends upon the cooperation of regulators, contractors, and the nuclear industry.

    Abstract: At the 2005 INMM/ESARDA Workshop in Santa Fe, New Mexico, I presented a paper entitled “Changing the Safeguards Culture: Broader Perspectives and Challenges.” That paper described a set of theoretical models that can be used as a basis for evaluating changes to safeguards culture. This paper builds on that theoretical discussion to address practical methods for influencing culture. It takes lessons from methods used to influence change in safety culture and security culture, and examines the applicability of these lessons to changing safeguards culture. Paper: At the 2005 INMM/ESARDA Workshop on “Changing the Safeguards Culture: Broader Perspectives and Challenges,” in Santa Fe, New Mexico, I presented a paper entitled “Changing the Safeguards Culture: Broader Perspectives and Challenges.” That paper, coauthored by Karyn R. Durbin and Andrew Van Duzer, described a set of theoretical models that can be used as a basis for evaluating changes to safeguards culture. This paper updates that theoretical discussion, and seeks to address practical methods for influencing culture. It takes lessons from methods used to influence change in safety culture and security culture, and examines the applicability of these lessons to changing safeguards culture. Implicit in this discussion is an understanding that improving a culture is not an end in itself, but is one method of improving the underlying discipline, that is safety, security, or safeguards. Culture can be defined as a way of life, or general customs and beliefs of a particular group of people at a particular time. There are internationally accepted definitions of safety culture and nuclear security culture. As yet, there is no official agreed upon definition of safeguards culture. At the end of the paper I will propose my definition. At the Santa Fe Workshop the summary by the Co-Chairs of Working Group 1, “The Further Evolution of Safeguards,” noted: “It is clear that ‘safeguards culture

    The Assistant Secretary of the Army for Research, Development and Acquisition directed the Army Safety Center to provide an audit of the causes of accidents and safety of use restrictions on recently fielded systems by tracking residual hazards back through the acquisition process. The objective was to develop ''lessons learned'' that could be applied to the acquisition process to minimize mishaps in fielded systems. System safety management lessons learned are defined as Army practices or policies, derived from past successes and failures, that are expected to be effective in eliminating or reducing specific systemic causes of residual hazards. They are broadly applicable and supportive of the Army structure and acquisition objectives. 29 refs., 7 figs.

    NASA policy requires each Program or Project to develop a plan for how they will address Lessons Learned. Projects have the flexibility to determine how best to promote and implement lessons learned. A large project might budget for a lessons learned position to coordinate elicitation, documentation and archival of the project lessons. The lessons learned process crosses all NASA Centers and includes the contactor community. o The Office of The Chief Engineer at NASA Headquarters in Washington D.C., is the overall process owner, and field locations manage the local implementation. One tool used to transfer knowledge between program and projects is the Lessons Learned Information System (LLIS). Most lessons come from NASA in partnership with support contractors. A search for lessons that might impact a new design is often performed by a contractor team member. Knowledge is not found with only one person, one project team, or one organization. Sometimes, another project team, or person, knows something that can help your project or your task. Knowledge sharing is an everyday activity at the Kennedy Space Center through storytelling, Kennedy Engineering Academy presentations and through searching the Lessons Learned Information system. o Project teams search the lessons repository to ensure the best possible results are delivered. o The ideas from the past are not always directly applicable but usually spark new ideas and innovations. Teams have a great responsibility to collect and disseminate these lessons so that they are shared with future generations of space systems designers. o Leaders should set a goal for themselves to host a set numbers of lesson learned events each year and do more to promote multiple methods of lessons learned activities. o High performing employees are expected to share their lessons, however formal knowledge sharing presentation are not the norm for many employees.

    Optimizing access to HIV pre-exposure prophylaxis (PrEP), an evidence-based HIV prevention resource, requires expanding healthcare providers’ adoption of PrEP into clinical practice. This qualitative study explored PrEP providers’ firsthand experiences relative to six commonly-cited barriers to prescription—financial coverage, implementation logistics, eligibility determination, adherence concerns, side effects, and anticipated behavior change (risk compensation)—as well as their recommendations for training PrEP-inexperienced providers. U.S.-based PrEP providers were recruited via direct outreach and referral from colleagues and other participants (2014–2015). One-on-one interviews were conducted in person or by phone, transcribed, and analyzed. The sample (n = 18) primarily practiced in the Northeastern (67%) or Southern (22%) U.S. Nearly all (94%) were medical doctors (MDs), most of whom self-identified as infectious disease specialists. Prior experience prescribing PrEP ranged from 2 to 325 patients. Overall, providers reported favorable experiences with PrEP implementation and indicated that commonly anticipated problems were minimal or manageable. PrEP was covered via insurance or other programs for most patients; however, pre-authorization requirements, laboratory/service provision costs, and high deductibles sometimes presented challenges. Various models of PrEP care and coordination with other providers were utilized, with several providers highlighting the value of clinical staff support. Eligibility was determined through joint decision-making with patients; CDC guidelines were commonly referenced but not considered absolute. Patient adherence was variable, with particularly strong adherence noted among patients who had actively sought PrEP (self-referred). Providers observed minimal adverse effects or increases in risk behavior. However, they identified several barriers with respect to accessing and engaging PrEP candidates. Providers offered

    This article examines the political, ideological, social, and economic processes by which the Argentinean economy was transformed, the structural consequences, and the policies responsible for dismantling the welfare state. The health care system reform during the 1990s was an important component in accomplishing the last objective. Analyses of the policies adopted after the crisis of 2001 reveal that, despite the discourse against international financial institutions, President Nestor Kirchner, elected in 2002, followed the same approach by accepting and applying the second generation of health reforms recommended by the World Bank and the Inter-American Development Bank with additional pressure from the World Trade Organization and several free trade agreements. This "new reform" furthered business opportunities for multinational corporations while further shrinking the state administration's role in supplying health, education, and other social services to people who need them more than ever. Social movements have emerged that are developing alternative projects and showing that, when the base is solidarity, "another world is possible." PMID:16524170

    Four 4760 Nms (3510 ft-lbf-s) Double Gimbal Control Moment Gyroscopes (DGCMG) with unlimited gimbal freedom about each axis were adopted by the International Space Station (ISS) Program as the non-propulsive solution for continuous attitude control. These CMGs with a life expectancy of approximately 10 years contain a flywheel spinning at 691 rad/s (6600 rpm) and can produce an output torque of 258 Nm (190 ft-lbf)1. One CMG unexpectedly failed after approximately 1.3 years and one developed anomalous behavior after approximately six years. Both units were returned to earth for failure investigation. This paper describes the Space Station Double Gimbal Control Moment Gyroscope design, on-orbit telemetry signatures and a summary of the results of both failure investigations. The lessons learned from these combined sources have lead to improvements in the design that will provide CMGs with greater reliability to assure the success of the Space Station. These lessons learned and design improvements are not only applicable to CMGs but can be applied to spacecraft mechanisms in general.

The exercise involved the state Iowa and Nebraska, NRC as the lead Federal agency, FRMAC (Federal Radiological Monitoring and Assessment Center), and several federal agencies with statutory emergency responsibility. FRMAC-93 was a major 2-day field exercise designed to determine the effectiveness, coordination, and operations of a DOE-managed FRMAC. Other objectives were to ensure that appropriate priorities were established and assistance was provided to the states and the lead Federal agency by FRMAC. Day 1 involved the Fort Calhoun evaluated plume phase exercise. On Day 2, the flow of data, which was slow initially, improved so that confidence of states and other federal responders in FRMAC support capabilities was high. The impact and lessons learned from FRMAC-93 provided the necessary impetus to make organizational and operational changes to the FRMAC program, which were put into effect in the DOE exercise FREMONT at Hanford 3 months later.

    On the basis of experience with ecological risk assessments and regulatory involvement in the process, a number of lessons can be learned relating to design, implementation, and reporting of ecological risk assessments. A number of case studies will be presented in order to evaluate the advantages and disadvantages of different approaches. Issues surrounding the selection of assessment and measurement endpoints, receptors, accuracy of models when compared with field data, bioavailability of chemicals, selection of appropriate reference sites, availability of relevant toxicological data, utility of bioassays, and accounting for temporal and seasonal variability, species adaptation, and ecological relevance will be examined. In addition, effective ways of dealing with limitations such as duration and cost of the assessments will be evaluated. Case studies ranging from large, complex Superfund sites to small, relatively simplistic sites will be included. By scrutinizing the approaches used and the outcomes of these case studies, insight can be gained that will allow risk assessors to deal with limitations and to focus future efforts to provide useful and relevant information and sound scientifically-based results.

  13. Science and Sandy: Lessons Learned

    2013-12-01

    Following Hurricane Sandy's impact on the mid-Atlantic region, President Obama established a Task Force to '...ensure that the Federal Government continues to provide appropriate resources to support affected State, local, and tribal communities to improve the region's resilience, health, and prosperity by building for the future.' The author was detailed from NOAA to the Task Force between January and June 2013. As the Task Force and others began to take stock of the region's needs and develop plans to address them, many diverse approaches emerged from different areas of expertise including: infrastructure, management and construction, housing, public health, and others. Decision making in this environment was complex with many interests and variables to consider and balance. Although often relevant, science and technical expertise was not always at the forefront of this process. This talk describes the author's experience with the Sandy Task Force focusing on organizing scientific expertise to support the work of the Task Force. This includes a description of federal activity supporting Sandy recovery efforts, the role of the Task Force, and lessons learned from developing a science support function within the Task Force.

  14. Huygens Highlights and lessons learned

    Ten years ago, on 14 January 2005, the Huygens Probe parachuted down to the surface of Titan, Saturn's largest moon. Huygens is part of the international Cassini/Huygens mission, a joint endeavor of NASA, the European Space Agency, and Agenzia Spaziale Italiana. Cassini/Huygens, comprising the NASA-provided Saturn Orbiter and the ESA-provided Huygens probe, was launched in October 1997. It arrived at Saturn in early July 2004. Huygens was released on the 3rd orbit around Saturn. It made measurements during the hypersonic entry, the descent, and for more than one hour on the surface. Unique in situ characterization of the atmosphere along the entry and descent trajectory and of the surface at the landing site was provided, revealing that many Earth-like processes were at work on Titan, a very fascinating methane world. Huygens observations also allowed inferring the ice crust thickness, hence an estimation of the depth of the icy crust/liquid water ocean interface. Huygens measurements are also used as ground-truth of the measurements made by the orbiter during Titan flybys. In this presentation, after a brief review of the major mission milestones, Huygens achievements are discussed in the context of the progress made in our understanding of Titan during the Cassini/Huygens mission. Lessons learned for the future in situ exploration of Titan are addressed. * Most of this work was performed while at ESA/ESTEC, Noordwijk, The Netherlands

  15. Lessons Learned from the Clementine Mission

    NASA Technical Reports Server (NTRS)

    1997-01-01

    According to BMDO, the Clementine mission achieved many of its technology objectives during its flight to the Moon in early 1994 but, because of a software error, was unable to test the autonomous tracking of a cold target. The preliminary analyses of the returned lunar data suggest that valuable scientific measurements were made on several important topics but that COMPLEX's highest-priority objectives for lunar science were not achieved. This is not surprising given that the rationale for Clementine was technological rather than scientific. COMPLEX lists below a few of the lessons that may be learned from Clementine. Although the Clementine mission was not conceived as a NASA science mission exactly like those planned for the Discovery program, many operational aspects of the two are similar. It is therefore worthwhile to understand the strengths and faults of the Clementine approach. Some elements of the Clementine operation that led to the mission's success include the following: (1) The mission's achievements were the responsibility of a single organization and its manager, which made that organization and that individual accountable for the final outcome; (2) The sponsor adopted a hands-off approach and set a minimum number of reviews (three); (3) The sponsor accepted a reasonable amount of risk and allowed the project team to make the trade-offs necessary to minimize the mission's risks while still accomplishing all its primary objectives; and (4) The development schedule was brief and the agreed-on funding (and funding profile) was adhered to. Among the operational shortcomings of Clementine were the following: (1) An overly ambitious schedule and a slightly lean budget (meaning insufficient time for software development and testing, and leading ultimately to human exhaustion); and (2) No support for data calibration, reduction, and analysis. The principal lesson to be learned in this category is that any benefits from the constructive application of higher

    The Vision for Space Exploration sets out a number of goals, involving both strategic and tactical objectives. These include returning the Space Shuttle to flight, completing the International Space Station, and conducting human expeditions to the Moon by 2020. Each of these goals has profound logistics implications. In the consideration of these objectives,a need for a study on NASA logistics lessons learned was recognized. The study endeavors to identify both needs for space exploration and challenges in the development of past logistics architectures, as well as in the design of space systems. This study may also be appropriately applied as guidance in the development of an integrated logistics architecture for future human missions to the Moon and Mars. This report first summarizes current logistics practices for the Space Shuttle Program (SSP) and the International Space Station (ISS) and examines the practices of manifesting, stowage, inventory tracking, waste disposal, and return logistics. The key findings of this examination are that while the current practices do have many positive aspects, there are also several shortcomings. These shortcomings include a high-level of excess complexity, redundancy of information/lack of a common database, and a large human-in-the-loop component. Later sections of this report describe the methodology and results of our work to systematically gather logistics lessons learned from past and current human spaceflight programs as well as validating these lessons through a survey of the opinions of current space logisticians. To consider the perspectives on logistics lessons, we searched several sources within NASA, including organizations with direct and indirect connections with the system flow in mission planning. We utilized crew debriefs, the John Commonsense lessons repository for the JSC Mission Operations Directorate, and the Skylab Lessons Learned. Additionally, we searched the public version of the Lessons Learned

  18. What Is Inside A Lesson Learned?

    NASA Astrophysics Data System (ADS)

    Scheer, S.

    2009-04-01

    The learning of lessons is something that is inherent to normal human behavior. All kind of human interaction experiences critical inspection after a severe or even disastrous event has occurred. Particular inspections have been undertaken in the field of natural disasters. Hence human risk management can continuously be improved according to lessons learned from previous disasters or with the outcome of experience shared with other stakeholders in that field. This paper shows the results of a lessons learned project over the past years: the NEDIES (Natural and Environmental Information Exchange System) deals with lessons learned during the classical risk management phases of prevention, preparedness and response At first glance a lesson is just pure text. Basically it mirrors what has been experienced within a certain context. Having a closer look at a lesson one finds out that a lesson refers to a specific emergency-triggering situation. A situation is more than a simple reference to a hazard: a "rapidly rising lake level" could have more meaning than "a flood". In order to take out positive information it is advisable not only to list up all potential benefits that could be drawn from a lesson; the explicit mentioning of benefits could be helpful in order to prepare further actions beforehand. Moreover one should also consider possible actions to take if that particular situation of the lesson exhibits again or elsewhere. In the case of rapidly rising lake level an a-priori prioritization of response actions could be done. The description of the situation is linked with other characteristics of the lesson; local issues as well as historical considerations can play a role. A flood in a densely populated town can produce different implications than a flood in the countryside. The benefits of the lesson and actions proposed could be linked with experiences made in the past. Other issues concern people involved: the addressees. Typical addressees are local decision

    1998-06-01

    Systematic evaluation of a project, product or other successes, and failures, is an important method for improving the performance of a company, as well as that of an individual. One should evaluate and determine if lessons learned can be applied to the systems and procedures being used in the company. Even if the company does not have to adjust its strategies, procedures, portfolio or systems as a result of lessons it has learned, there may be pointers to communicate to staff. It is easy for many aspects of a system to become outdated, particularly in an organization that is growing or changing rapidly. It is therefore generally appropriate to evaluate the company's regulatory compliance, toxicology compliance, clinical auditing practices and other appropriate systems on an annual or biannual basis. Most lessons of success or failure are specific to a single situation because of the combination of people, drug, competition, priorities and many other factors involved, and cannot be extrapolated to other situations. Some general lessons and principles are presented that will facilitate drug discovery, development and marketing. PMID:15616644

    2013-01-01

    The aim of this study is to describe the process of staff and patient adoption and compliance of a real-time locating system (RTLS) across two health care settings and present lessons learned. While previous work has examined the technological feasibility of tracking staff and patients in a health care setting in real-time, these studies have not described the critical adoption issues that must be overcome for deployment. The ability to track and monitor individual staff and patients presents new opportunities for improving workflow, patient health and reducing health care costs. A RTLS is introduced in both a long-term care and a polytrauma transitional rehabilitation program (PTRP) in a Veterans Hospital to track staff and patient locations and five lessons learned are presented from our experiences and responses to emergent technological, work-related and social barriers to adoption. We conclude that successful tracking in a health care environment requires time and careful consideration of existing work, policies and stakeholder needs which directly impact the efficacy of the technology.

  6. From Lessons Learned Towards Disaster Reduction Measures

    NASA Astrophysics Data System (ADS)

    Scheer, S.

    2009-04-01

    Efforts have been undertaken over the past years in eliciting and collecting lessons as they could be derived from the outcome of natural disasters management. Lessons are viewed from various perspectives according to • the situation or triggering event which led to the disaster • the local or time-dependent characteristics of this situation and further analysed according to • their benefits • necessary actions to do in order to better implement a lesson. The explicit elicitation of all that information fosters the generation of good practices and the identification of bad practices. Hence the creation of appropriate measures concerning disaster reduction issues could be positively influenced. On the other hand, continuous efforts are undertaken in the field of establishing lists of disaster reduction measures for all major hazards. Those measures comprise both concrete techniques (e.g. a tool or a structure) and advisory techniques (teaching practices or procedural instructions). This paper gives an overview of ways to "produce" disaster reduction measures from lessons learned; moreover it will explain how context-dependent analysis of lessons can potentially lead to alterations of existing disaster reduction measures.

    A comprehensive database of lessons learned that corresponds with relevant technical standards would be a boon to technical personnel and standards developers. The authors discuss the emergence of one such database within NASA, and show how and why the incorporation of lessons learned into technical standards databases can be an indispensable tool for government and industry. Passed down from parent to child, teacher to pupil, and from senior to junior employees, lessons learned have been the basis for our accomplishments throughout the ages. Government and industry, too, have long recognized the need to systematically document And utilize the knowledge gained from past experiences in order to avoid the repetition of failures and mishaps. The use of lessons learned is a principle component of any organizational culture committed to continuous improvement. They have formed the foundation for discoveries, inventions, improvements, textbooks, and technical standards. Technical standards are a very logical way to communicate these lessons. Using the time-honored tradition of passing on lessons learned while utilizing the newest in information technology, the National Aeronautics and Space Administration (NASA) has launched an intensive effort to link lessons learned with specific technical standards through various Internet databases. This article will discuss the importance of lessons learned to engineers, the difficulty in finding relevant lessons learned while engaged in an engineering project, and the new NASA project that can help alleviate this difficulty. The article will conclude with recommendations for more expanded cross-sectoral uses of lessons learned with reference to technical standards.

    The Mars Program has recently been informed of the Planetary Protection Subcommittee (PPS) recommendation, which was endorsed by the NAC, concerning Mars Science Lab (MSL) lessons learned and knowledge capture. The Mars Program has not had an opportunity to consider any decisions specific to the PPS recommendation. Some of the activities recommended by the PPS would involve members of the MSL flight team who are focused on cruise, entry descent & landing, and early surface operations; those activities would have to wait. Members of the MSL planetary protection team at JPL are still available to support MSL lessons learned and knowledge capture; some of the specifically recommended activities have already begun. The Mars Program shares the PPS/NAC concerns about loss of potential information & expertise in planetary protection practice.

  10. Turning Operational Lessons Learned into Design Reality

    NASA Technical Reports Server (NTRS)

    Brady, David A.

    2009-01-01

    The capabilities and limitations of a particular system design are well known by the people who operate it. Operational workarounds, operational notes and lessons learned are traditional methods for dealing with and documenting design shortcomings. The beginning of each new program brings the hope that hard-learned lessons will be incorporated into the next new system. But often operations personnel find their well-intentioned efforts frustrated by an inability to have their inputs considered by design personnel who have strictly-scoped requirements that are coupled with ambitious cost and schedule targets. There is a way for operational inputs to make it into the design, but the solution involves a combination of organizational culture and technical data. Any organization that utilizes this approach can realize significant benefits over the life cycle of their project.

A short-life lubricated mechanisms complete their life test qualification requirements after a few cycles. The mechanisms include the hinges, motors and bearings for deployment, release mechanisms, latches, release springs and support shops. Performance testing can be difficult and expensive but must be accomplished. A long-life lubricated mechanisms requires up to 5 years of life testing, or 10 to 100 years of successful flight. The long-life mechanisms include reaction wheels, momentum wheels, antenna gimbals, solar array drives, gyros and despin mechanisms. Several instances of how a mechanisms failed either in test, or in space use, and the lessons learned from these failures are reviewed. The effect of the movement away from CFC-113 cleaning solvent to ODC (Ozone-Depleting Chemical) -free is reviewed, and some of the alternatives are discussed.

    Bickford, J.C.

    1997-12-12

    A lesson learned as defined in DOE-STD-7501-95, Development of DOE Lessons Learned Programs, is: A ``good work practice`` or innovative approach that is captured and shared to promote repeat applications or an adverse work practice or experience that is captured and shared to avoid a recurrence. The key word in both parts of this definition is ``shared``. This document was published to share a wide variety of recent Hanford experiences with other DOE sites. It also provides a valuable tool to be used in new employee and continuing training programs at Hanford facilities and at other DOE locations. This manual is divided into sections to facilitate extracting appropriate subject material when developing training modules. Many of the bulletins could be categorized into more than one section, however, so examination of other related sections is encouraged.

    Background Site-specific content configuration of vendor-based Electronic Health Records (EHRs) is a vital step in the development of standardized and interoperable content that can be used for clinical decision-support, reporting, care coordination, and information exchange. The multi-site, multi-stakeholder Acute Care Documentation (ACD) project at Partners Healthcare Systems (PHS) aimed to develop highly structured clinical content with adequate breadth and depth to meet the needs of all types of acute care clinicians at two academic medical centers. The Knowledge Management (KM) team at PHS led the informatics and knowledge management effort for the project. Objectives We aimed to evaluate the role, governance, and project management processes and resources for the KM team’s effort as part of the standardized clinical content creation. Methods We employed the Center for Disease Control’s six step Program Evaluation Framework to guide our evaluation steps. We administered a forty-four question, open-ended, semi-structured voluntary survey to gather focused, credible evidence from members of the KM team. Qualitative open-coding was performed to identify themes for lessons learned and concluding recommendations. Results Six surveys were completed. Qualitative data analysis informed five lessons learned and thirty specific recommendations associated with the lessons learned. The five lessons learned are: 1) Assess and meet knowledge needs and set expectations at the start of the project; 2) Define an accountable decision-making process; 3) Increase team meeting moderation skills; 4) Ensure adequate resources and competency training with online asynchronous collaboration tools; 5) Develop focused, goal-oriented teams and supportive, consultative service based teams. Conclusions Knowledge management requirements for the development of standardized clinical content within a vendor-based EHR among multi-stakeholder teams and sites include: 1) assessing and meeting

    1994-06-01

    The thesis provides lessons learned from experiments conducted by the 11th Air Force to verify the capabilities of two vendor-produced Radar Data Management Systems (RDMS). The first part of the thesis provides background information explaining the impetus for such experiments and why a lessons learned approach was taken. The experimental plan and the final report from the PACAF experiments are analyzed using evaluation tools taught in the C3 curriculum at the Naval Postgraduate School. The lessons learned from the mistakes made during these experiments are applied to produce a revised experimental plan. A lessons learned section follows the analysis. This section discusses specific lessons learned from the 11th Air Force experiments as well as more general lessons learned by the author. The thesis concludes with two chapters that provide overall conclusions and a summary, and recommendations for future work that can be accomplished in the area of radar data management.

    2011-11-01

    The year 2010 marked the 25th anniversary of the Center for Army Lessons Learned (CALL) as well as the Army Medical Department (AMEDD) Center and School's Lessons Learned Division. In the aftermath of Operation Urgent Fury in 1983, the Army recognized the need to create an organization whose sole purpose was to collect, review, and analyze lessons learned and created the CALL in 1985 at Fort Leavenworth, Kansas. The AMEDD followed suit and established the Medical Information System/AMEDD Lessons Learned office under the Directorate of Evaluation and Standardization to research and compile lessons learned as the AMEDD's point of contact for the CALL program. Over these past 25 years the AMEDD Center and School Lessons Learned program evolved and underwent organizational realignments, but the overall mission continues to promote changes either directly or indirectly in the AMEDD's Doctrine, Organizations, Training, Leader Development, Materiel, Personnel and Facilities domains and capabilities to provide combat health service support on the battlefield.

  6. Best Practices for Researching and Documenting Lessons Learned

    NASA Technical Reports Server (NTRS)

    Goodman, John L.

    2007-01-01

    Identification, resolution, and avoidance of technical and programmatic issues are important for ensuring safe and successful space missions. Although the importance of applying lessons learned to reduce risk is frequently stressed, there is little material available to help technical and management personnel research and document lessons learned. Collecting, researching, identifying, and documenting lessons learned that will be useful to current and future management and engineering personnel is not always a straightforward task. This white paper presents lessons learned and best practices concerning the research and documentation of technical and organizational lessons learned. It is intended to enable organizations to initiate or improve lessons learned research and documentation efforts. The content of this white paper is based on four technical lessons learned projects conducted by the United Space Alliance (USA) Flight Design and Dynamics Department, in support of the NASA/JSC Flight Design and Dynamics Division. Each project published a report, titled as follows: GPS Lessons Learned From the ISS, Space Shuttle and X-38; Lessons Learned From Seven Space Shuttle Missions; Space Shuttle Rendezvous and Proximity Operations Experience Report; and Navigation Technical History with Lessons Learned. The four projects were different in availability of subject matter experts and primary source material, subject scope, and the level of effort required to produce the final report. However, generic lessons can be drawn from all of them. The best practices will be discussed by the phases of report research and development: Defining Report Requirements, Project Organization, and Schedule, Collection and Analysis of Source Material, Writing and Integrating the Report, and Review and Revision of the Report.

    These six lessons learned for greater success with your Patient Focused communications can help keep your cultural change process in sync with your operational change process. Of course, there are other key elements of the former, including: formal Patient Focused educational programs; restructured Human Resources "systems" (e.g., job descriptions and compensation programs); and migration toward greater organizational empowerment and more self-directed work teams. Still, your Patient Focused communications campaign will spearhead the cultural change process. As such, it will have the opportunity to make the very first impact. Basically, your communications can make or break your Patient Focused Care program from Day One. It's up to you--learn the lessons learned by others and your organization may follow the words of Marx rather than those of Brand: "Workers of the world, unite (on behalf of your Patient Focused Care program)!"

    Fragola, J. R.

    1992-07-01

    As design concepts involving nuclear power are developed for space missions, prudence requires a consideration of the historical perspective provided by the commerical nuclear power generating station industry. This would allow the aerospace industry to take advantage of relevant historical experience, drawing from the best features and avoiding the pitfalls which appear to have stifled the growth of the commercial nuclear industry as a whole despite its comparatively admirable safety performance record. This paper provides some history of the development of commercial nuclear plant designs, and discusses the lessons which have been learned and how they apply to the space nuclear propulsion situation.

    A review is presented of some of the lessons learned from wind tunnel tests since World War II. Wind tunnels achieved a very high productivity rate during the war due in part to development testing of numerous military aircraft concepts. Following the war, in addition to development testing, a rapid increase in basic research testing occurred in order to explore areas of interest revealed by the conduct of war and to expand on advanced technology that became available from Germany and Italy. The research test areas discussed are those primarily related to the transition from subsonic flight to supersonic flight.

    A graduate student received a laser eye injury from a femtosecond Ti:sapphire laser beam while adjusting a polarizing beam splitter optic. The direct causes for the accident included failure to follow safe alignment practices and failure to wear the required laser eyewear protection. Underlying root causes included inadequate on-the-job training and supervision, inadequate adherence to requirements, and inadequate appreciation for dimly visible beams outside the range of 400-700nm. This paper describes how the accident occurred, discusses causes and lessons learned, and describes corrective actions being taken.

  1. Lessons learned: DC-X

    NASA Technical Reports Server (NTRS)

    Steinmeyer, D. A.

    1996-01-01

    The DC-X was conceived and developed specifically to lay the ground work for significantly lowering the cost of space operations. The system design was based on an initial set of program goals and a finite, limited set of resources. The goal in its simplest terms was to demonstrate vertical landing after rotation of the vehicle from a nose-first to an engines-first altitude. Finite resources actually drove the selection of a robust design to reduce fabrication and preflight testing costs. The result was a system with a large amount of flexibility which allowed expansion of the test goals as the system, and test program, evolved. The use of the vehicle flight computer interfacing with the ground control system for flight crew training was also not an initial concept. However, by defining an architecture for the system control modes which allowed additions and modifications as learning progressed, the 6 DOF codes used for flight controls software development were transported to the operating system to be used in a simulated flight mode. Flight data reduction was also greatly improved as the program progressed, and the data needs and presentation were refined. The software, avionics hardware, and the FOCC system development proceeded ahead of the vehicle, primarily because most of the hardware elements were existing at the outset of the program. The Built-in-Test (BIT) for avionics and propulsion systems were adequate. Particularly the flight readiness system which verified the vehicle health after engine start and before throttle-up for flight.

    Zapata, Edgar; Rhodes, Russell E.; Robinson, John W.

    2010-01-01

    This paper will review lessons learned for space transportation systems from the viewpoint of the NASA, Industry and academia Space Propulsion Synergy Team (SPST). The paper provides the basic idea and history of "lessons learned". Recommendations that are extremely relevant to NASA's future investments in research, program development and operations are"'provided. Lastly, a novel and useful approach to documenting lessons learned is recommended, so as to most effectively guide future NASA investments. Applying lessons learned can significantly improve access to space for cargo or people by focusing limited funds on the right areas and needs for improvement. Many NASA human space flight initiatives have faltered, been re-directed or been outright canceled since the birth of the Space Shuttle program. The reasons given at the time have been seemingly unique. It will be shown that there are common threads as lessons learned in many a past initiative.

  3. Flight Planning Branch Space Shuttle Lessons Learned

    Price, Jennifer B.; Scott, Tracy A.; Hyde, Crystal M.

    2011-01-01

    Planning products and procedures that allow the mission flight control teams and the astronaut crews to plan, train and fly every Space Shuttle mission have been developed by the Flight Planning Branch at the NASA Johnson Space Center. As the Space Shuttle Program ends, lessons learned have been collected from each phase of the successful execution of these Shuttle missions. Specific examples of how roles and responsibilities of console positions that develop the crew and vehicle attitude timelines will be discussed, as well as techniques and methods used to solve complex spacecraft and instrument orientation problems. Additionally, the relationships and procedural hurdles experienced through international collaboration have molded operations. These facets will be explored and related to current and future operations with the International Space Station and future vehicles. Along with these important aspects, the evolution of technology and continual improvement of data transfer tools between the shuttle and ground team has also defined specific lessons used in the improving the control teams effectiveness. Methodologies to communicate and transmit messages, images, and files from Mission Control to the Orbiter evolved over several years. These lessons have been vital in shaping the effectiveness of safe and successful mission planning that have been applied to current mission planning work in addition to being incorporated into future space flight planning. The critical lessons from all aspects of previous plan, train, and fly phases of shuttle flight missions are not only documented in this paper, but are also discussed as how they pertain to changes in process and consideration for future space flight planning.

  4. The Network Operations Control Center upgrade task: Lessons learned

    NASA Technical Reports Server (NTRS)

    Sherif, J. S.; Tran, T.-L.; Lee, S.

    1994-01-01

    This article synthesizes and describes the lessons learned from the Network Operations Control Center (NOCC) upgrade project, from the requirements phase through development and test and transfer. At the outset, the NOCC upgrade was being performed simultaneously with two other interfacing and dependent upgrades at the Signal Processing Center (SPC) and Ground Communications Facility (GCF), thereby adding a significant measure of complexity to the management and overall coordination of the development and transfer-to-operations (DTO) effort. Like other success stories, this project carried with it the traditional elements of top management support and exceptional dedication of cognizant personnel. Additionally, there were several NOCC-specific reasons for success, such as end-to-end system engineering, adoption of open-system architecture, thorough requirements management, and use of appropriate off-the-shelf technologies. On the other hand, there were several difficulties, such as ill-defined external interfaces, transition issues caused by new communications protocols, ambivalent use of two sets of policies and standards, and mistailoring of the new JPL management standard (due to the lack of practical guidelines). This article highlights the key lessons learned, as a means of constructive suggestions for the benefit of future projects.

    Plastic litter is an environmental problem of great concern. Despite the magnitude of the plastic pollution in our water bodies, only limited scientific understanding is available about the risk to the environment, particularly for microplastics. The apparent magnitude of the problem calls for quickly developing sound scientific guidance on the ecological risks of microplastics. The authors suggest that future research into microplastics risks should be guided by lessons learned from the more advanced and better understood areas of (eco) toxicology of engineered nanoparticles and mixture toxicity. Relevant examples of advances in these two fields are provided to help accelerate the scientific learning curve within the relatively unexplored area of microplastics risk assessment. Finally, the authors advocate an expansion of the "vector effect" hypothesis with regard to microplastics risk to help focus research of microplastics environmental risk at different levels of biological and environmental organization.

The developments I've been involved with do make use of the ability to adapt and change, and there have been Bumps in the Road here and there, and I'll tell you a little bit more about that during this Talk.

  7. Receiver System: Lessons Learned From Solar Two

    SciTech Connect

    LITWIN, ROBERT Z.; PACHECO, JAMES E.

    2002-03-01

    The Boeing Company fabricated the Solar Two receiver as a subcontractor for the Solar Two project. The receiver absorbed sunlight reflected from the heliostat field. A molten-nitrate-salt heat transfer fluid was pumped from a storage tank at grade level, heated from 290 to 565 C by the receiver mounted on top of a tower, then flowed back down into another storage tank. To make electricity, the hot salt was pumped through a steam generator to produce steam that powered a conventional Rankine steam turbine/generator. This evaluation identifies the most significant Solar Two receiver system lessons learned from the Mechanical Design, Instrumentation and Control, Panel Fabrication, Site Construction, Receiver System Operation, and Management from the perspective of the receiver designer/manufacturer. The lessons learned on the receiver system described here consist of two parts: the Problem and one or more identified Solutions. The appendix summarizes an inspection of the advanced receiver panel developed by Boeing that was installed and operated in the Solar Two receiver.

Launched on January 6 1998, the suite of five instruments is measuring water/ice to a sensitivity of 50 ppm (hydrogen), detecting key elemental constituents, gas release events and mapping the Moon's gravitational and magnetic fields. The mission is described with emphasis on the first scientific results and lessons learned from managing a very low cost project. A mission overview and systems description is given along with final mission trajectories. Lessons learned from government-industry teaming, new modes of project management, and novel contractual arrangements are discussed. The suite of five instruments (neutron spectrometer, alpha particle spectrometer, gamma-ray spectrometer, electron reflectometer and magnetometer) is outlined with attention to final technical performance as well as development on a constrained budget and schedule. A review of our novel approaches to education and public outreach is discussed and a summary with suggestions and implications for future missions is provided.

  10. 2010 CEOS Field Reflectance Intercomparisons Lessons Learned

    2011-01-01

    This paper summarizes lessons learned from the 2009 and 2010 joint field campaigns to Tuz Golu, Turkey. Emphasis is placed on the 2010 campaign related to understanding the equipment and measurement protocols, processing schemes, and traceability to SI quantities. Participants in both 2009 and 2010 used an array of measurement approaches to determine surface reflectance. One lesson learned is that even with all of the differences in collection between groups, the differences in reflectance are currently dominated by instrumental artifacts including knowledge of the white reference. Processing methodology plays a limited role once the bi-directional reflectance of the white reference is used rather than a hemispheric-directional value. The lack of a basic set of measurement protocols, or best practices, limits a group s ability to ensure SI traceability and the development of proper error budgets. Finally, rigorous attention to sampling methodology and its impact on instrument behavior is needed. The results of the 2009 and 2010 joint campaigns clearly demonstrate both the need and utility of such campaigns and such comparisons must continue in the future to ensure a coherent set of data that can span multiple sensor types and multiple decades.

    Since being established in 2005, the Ares Projects at Marshall Space Flight Center have been making steady progress designing, building, testing, and flying the next generation of exploration launch vehicles. Ares is committed to rebuilding crucial capabilities from the Apollo era that made the first human flights to the Moon possible, as well as incorporating the latest in computer technology and changes in management philosophy. One example of an Apollo-era practice has been giving NASA overall authority over vehicle integration activities, giving civil service engineers hands-on experience in developing rocket hardware. This knowledge and experience help make the agency a "smart buyer" of products and services. More modern practices have been added to the management tool belt to improve efficiency, cost effectiveness, and institutional knowledge, including knowledge management/capture to gain better insight into design and decision making; earned value management, where Ares won a NASA award for its practice and implementation; designing for operability; and Lean Six Sigma applications to identify and eliminate wasted time and effort. While it is important to learn technical lessons like how to fly and control unique rockets like the Ares I-X flight test vehicle, the Ares management team also has been learning important lessons about how to manage large, long-term projects.

    2010-11-01

    As part of the Global Threat Reduction Initiative, the Neutron Radiography Reactor (NRAD) at the Idaho National Laboratory (INL) was converted from using highly enriched uranium (HEU) to low enriched uranium (LEU) fuel. After the conversion, NRAD resumed operations and is meeting operational requirements. Radiography image quality and the number of images that can be produced in a given time frame match pre-conversion capabilities. However, following the conversion, NRAD’s excess reactivity with the LEU fuel was less than it had been with the HEU fuel. Although some differences between model predictions and actual performance are to be expected, the lack of flexibility in NRAD’s safety documentation prevented adjusting the reactivity by adding more fuel, until the safety documentation could be modified. To aid future reactor conversions, a reactivity-focused Lessons Learned meeting was held. This report summarizes the findings of the lessons learned meeting and addresses specific questions posed by DOE regarding NRAD’s conversion and reactivity.

    2008-04-01

    There is a growing consensus that traditional instruction in basic science courses, in institutions of higher learning, do not lead to the desired results. Most of the students who complete these courses do not gain deep knowledge about the basic concepts and develop a negative approach to the sciences. In order to deal with this problem, a variety of methods have been proposed and implemented, during the last decade, which focus on the "active learning" of the participating students. We found that the methods developed in MIT and NCSU were fruitful and we adopted their approach. Despite research-based evidence of the success of these methods, they are often met by the resistance of the academic staff. This article describes how one institution of higher learning organized itself to introduce significant changes into its introductory science courses, as well as the stages teachers undergo, as they adopt innovative teaching methods. In the article, we adopt the Rogers model of the innovative-decision process, which we used to evaluate the degree of innovation adoption by seven members of the academic staff. An analysis of interview and observation data showed that four factors were identified which influence the degree innovation adoption: (1) teacher readiness to seriously learn the theoretical background of "active learning"; (2) the development of an appropriate local model, customized to the beliefs of the academic staff; (3) teacher expertise in information technologies, and (4) the teachers' design of creative solutions to problems that arose during their teaching.

  19. Lessons Learned from JTA Tester Safety Studies

    SciTech Connect

    2001-05-01

    EP401575, Issue C, calls out a requirement to perform safety studies for testers that are used to accept Joint Test Assembly (JTA) product at Pantex (Reference 1). The underlying motivation is to ensure that personnel hazards due to inadvertent initiation of electro-explosive devices (EEDs) during JTA testing are understood and minimized. Studies have been performed on the B61-7/11 JTA, B61-3/4/10 JTA, B83 JTA, and W76 Type 2F testers at Pantex (References 2-5). Each of these studies includes an examination of the relevant Pantex tester as well as the instrumentation and War Reserve (WR) hardware. In performing these analyses, several themes have emerged that could be useful for the Phase 6.3 design efforts for the weapons, the associated instrumentation, and the JTA testers. This report summarizes the lessons learned from these studies. Note that in some cases, the recommendations provided below to enhance safety during JTA testing operations (e.g., adding isolation resistors in the monitoring lines) may result in a reliability degradation or other surety impact. Thus it is important to consider these lessons learned in the context of the overall design and to make tradeoffs in light of the integrated surety objectives. The lessons learned are listed in five different categories, summarized as: (1) Instrumentation considerations; (2) WR design considerations; (3) Tester considerations; (4) Administrative procedures during JTA assembly; and (5) Administrative procedures prior to and during JTA testing. The first three focus on minimizing the probability of inadvertent application of power to EED initiation lines due to component, connector, and assembly failures. The last two describe procedural steps that can be taken at Pantex to either minimize the risk (e.g., by ensuring that tester power supplies cannot supply excessive power to the unit under test) or to mitigate the consequences of unexpected EED initiation (e.g., by instructing test operators to avoid

    2015-03-01

    Social support has been a topic of research for nearly 50 years, and its applications to prevention and intervention have grown significantly, including programs advancing child protection. This article summarizes the central conclusions of the 1994 review of research on social support and the prevention of child maltreatment prepared for the U.S. Advisory Board on Child Abuse and Neglect, and surveys advances in the field since its publication. Among the lessons learned twenty years ago are (a) the diversity of the social support needs of at-risk families and their association with child endangerment, (b) the need to supplement the emotionally affirmative aspects of social support with efforts to socialize parenting practices and monitor child well-being, (c) the desirability of integrating formal and informal sources of social support for recipients, and (d) the importance of considering the complex recipient reactions to receiving support from others. The lessons we are now learning derive from research exploring the potential of online communication to enhance social support, the neurobiology of stress and its buffering through social support, and the lessons of evaluation research that are identifying the effective ingredients of social support interventions.

  2. Anthropology and Epidemiology: learning epistemological lessons through a collaborative venture

    PubMed Central

    Béhague, Dominique Pareja; Gonçalves, Helen; Victora, Cesar Gomes

    2009-01-01

    Collaboration between anthropology and epidemiology has a long and tumultuous history. Based on empirical examples, this paper describes a number of epistemological lessons we have learned through our experience of cross-disciplinary collaboration. Although critical of both mainstream epidemiology and medical anthropology, our analysis focuses on the implications of addressing each discipline’s main epistemological differences, while addressing the goal of adopting a broader social approach to health improvement. We believe it is important to push the boundaries of research collaborations from the more standard forms of “multidisciplinarity,” to the adoption of theoretically imbued “interdisciplinarity.” The more we challenge epistemological limitations and modify ways of knowing, the more we will be able to provide in-depth explanations for the emergence of disease-patterns and thus, to problem-solve. In our experience, both institutional support and the adoption of a relativistic attitude are necessary conditions for sustained theoretical interdisciplinarity. Until researchers acknowledge that methodology is merely a human-designed tool to interpret reality, unnecessary methodological hyper-specialization will continue to alienate one field of knowledge from the other.

    Lessons Learned have been the basis for our accomplishments throughout the ages. They have been passed down from father to son, mother to daughter, teacher to pupil, and older to younger worker. Lessons Learned have also been the basis for NASA's accomplishments for more than forty years. Both government and industry have long recognized the need to systematically document and utilize the knowledge gained from past experiences in order to avoid the repetition of failures and mishaps. Lessons Learned have formed the foundation for discoveries, inventions, improvements, textbooks, and Technical Standards.

    2013-05-01

    This report examines the lessons learned process by a review of the literature in a variety of disciplines, and is intended as a guidepost for organizations that are considering the implementation of their own closed-loop learning process. Lessons learned definitions are provided within the broader context of knowledge management and the framework of a learning organization. Shortcomings of existing practices are summarized in an attempt to identify common pitfalls that can be avoided by organizations with fledgling experiences of their own. Lessons learned are then examined through a dual construct of both process and mechanism, with emphasis on integrating into organizational processes and promoting lesson reuse through data attributes that contribute toward changed behaviors. The report concludes with recommended steps for follow-on efforts.

    our diverse participants was a constant challenge for us as instructors. In summer 2008, the course was organized so that fundamentals (chemistry, heat transfer, convection, physics) were taught in the first week and then applied in broader topics (water cycle, carbon cycle, weather and precipitation) in the second week. Learning these fundamentals was challenging for many teachers. Furthermore, the organization of topics caused frustration because there was not enough connection to the broader concepts of the course. In summer 2009, we rearranged the topics and interwove fundamentals with contextual topics within each week. We found this approach to be more successful in engaging and educating the teachers. The most successful activities were often the simplest to organize. Valuable instructional strategies included daily assessments in the form of morning quizzes, keeping a class website with all course materials, and centering the major project of the course around a lesson that teachers would design for their particular context. We saw a dramatic improvement in pre- and post-assessment test scores, with the class average increasing from 58% (pre-test) to 95% (post-test).

    For the past 6 years, the US Department of Energy (DOE) Office of Facility Safety Analysis (EH-32) has contracted Westinghouse Hanford Company (WHC) to conduct compliance testing on DOE Type A packagings. The packagings are tested for compliance with the U.S. Department of Transportation (DOT) Specification 7A, general packaging, Type A requirements. The DOE has shared the Type A packaging information throughout the nuclear materials transportation community. During testing, there have been recurring areas of packaging design that resulted in testing delays and/or initial failure. The lessons learned during the testing are considered a valuable resource. DOE requested that WHC share this resource. By sharing what is and can be encountered during packaging testing, individuals will hopefully avoid past mistakes.

    Southern California has a history of major earthquakes and also has one of the largest metropolitan areas in the United States. The 1994 Northridge Earthquake challenged the industrial facilities and lifetime infrastructure in the northern Los Angeles (LA) area. Lawrence Livermore National Laboratory (LLNL) sent a team of engineers to conduct an earthquake damage investigation in the Northridge area, on a project funded jointly by the United States Nuclear Regulatory Commission (USNRC) and the United States Department of Energy (USDOE). Many of the structures, systems, and components (SSCs) and lifelines that suffered damage are similar to those found in nuclear power plants and in USDOE facilities. Lessons learned from these experiences can have some applicability at commercial nuclear power plants.

    The International Atomic Energy Agency's (IAEA) Department of Safeguards uses complex instrumentation for the application of safeguards at nuclear facilities around the world. Often, this equipment is developed through cooperation with member state support programs because the Agency's requirements are unique and are not met by commercially available equipment. Before approving an instrument or system for routine inspection use, the IAEA subjects it to a series of tests designed to evaluate its reliability. In 2000, the IAEA began to observe operational failures in digital surveillance systems. In response to the observed failures, the IAEA worked with the equipment designer and manufacturer to determine the cause of failure. An action plan was developed to correct the performance issues and further test the systems to make sure that additional operational issues would not surface later. This paper addresses the steps taken to address operation issues related to digital image surveillance systems and the lessons learned during this process.

    Using two different unmanned aerial vehicles (UAVs) mounted with cameras, we created a digital elevation model (DEM) of the lower 12 km^2 of Tasman Glacier, South Island, New Zealand in March 2014. The project served primarily as a proof-of-concept, and here we discuss the lessons learned, emphasizing the practical, logistical, and flight issues. We tested two different fixed-wing airframes -- a twin-boom tradition and flying wing; two different camera types, both consumer-grade RGB; and various combinations of RC and telemetry radios. We used both commercial and open-source photogrammetry software to create the mosaic and DEM imagery. Some of the most critical UAV-specific issues are: access to a launch/landing site, adequate landing zones, range, airspace contention with manned aircraft, and hardware reliability. While UAVs provide a lower-cost method for photogrammetry access, it also comes with a unique set of challenges.

    This paper describes the design, testing, and lessons learned during the development of the Advanced Topographic Laser Altimeter System (ATLAS) Beam Steering Mechanism (BSM). The BSM is a 2 degree-of-freedom tip-tilt mechanism for the purpose of pointing a flat mirror to tightly control the co-alignment of the transmitted laser and the receiver telescope of the ATLAS instrument. The high resolution needs of the mission resulted in sub-arcsecond pointing and knowledge requirements, which have been met. Development of the methodology to verify performance required significant effort. The BSM will fly as part of the Ice, Cloud, and Elevation Satellite II Mission (ICESat II), which is scheduled to be launched in 2017. The ICESat II primary mission is to map the Earth's surface topography for the determination of seasonal changes of ice sheet thickness and vegetation canopy thickness to establish long-term trends.

    2011-01-01

    Few drugs have been labeled for pediatric cardiovascular indications and many children with cardiac disease are prescribed drugs off-label. Recent initiatives have narrowed this gap and as a result there are an increasing number of cardiology trials in the pediatric population. Many studies, however, have either failed to show a dose response in children or have not shown efficacy in children when they have established efficacy in adults. Clinical trials are challenging in children; many factors such as lack of development of a liquid formulation, failure to fully incorporate pharmacokinetic information into trial design, poor dose selection, the lack of clinical equipoise, and the use of difficult surrogate and composite primary endpoints have led to the difficulties and failures observed in several pediatric cardiovascular trials. These lessons learned may help to inform future pediatric clinical trial development. PMID:21242809

    The Sellafield site in North West England has over 240 active facilities covering the full nuclear cycle from fuel manufacture through generation, reprocessing and waste treatment. The Sellafield decommissioning programme was formally initiated in the mid 1980s though several plants had been decommissioned prior to this primarily to create space for other plants. Since the initiation of the programme 7 plants have been completely decommissioned, significant progress has been made in a further 16 and a total of 56 major project phases have been completed. This programme update will explain the decommissioning arrangements and strategies and illustrate the progress made on a number of the plants including the Windscale Pile Chimneys, the first reprocessing plan and plutonium plants. These present a range of different challenges and requiring approaches from fully hands on to fully remote. Some of the key lessons learned will be highlighted.

  19. Evolutionary fire ecology: lessons learned from pines.

    PubMed

    Pausas, Juli G

    2015-05-01

    Macroevolutionary studies of the genus Pinus provide the oldest current evidence of fire as an evolutionary pressure on plants and date back to ca. 125 million years ago (Ma). Microevolutionary studies show that fire traits are variable within and among populations, especially among those subject to different fire regimes. In addition, there is increasing evidence of an inherited genetic basis to variability in fire traits. Added together, pines provide compelling evidence that fire can exert an evolutionary pressure on plants and, thus, shape biodiversity. In addition, evolutionary fire ecology is providing insights to improve the management of pine forests under changing conditions. The lessons learned from pines may guide research on the evolutionary ecology of other taxa. PMID:25814325

    A hierarchical Extensible Markup Language(XML) database called XCALIBR (XML Analysis LIBRary) has been developed by Millennium Program to assist in technology investment (ROI) analysis and technology Language Capability the New return on portfolio optimization. The database contains mission requirements and technology capabilities, which are related by use of an XML dictionary. The XML dictionary codifies a standardized taxonomy for space missions, systems, subsystems and technologies. In addition to being used for ROI analysis, the database is being examined for use in project planning, tracking and documentation. During the past year, the database has moved from development into alpha testing. This paper describes the lessons learned during construction and testing of the prototype database and the motivation for moving from an XML taxonomy to a standard XML-based ontology.

    2003-01-01

    Among the principal objectives of the Phase 1 NASA/Mir program were for the United States to gain experience working with an international partner, to gain working experience in long-duration space flight, and to gain working experience in planning for and executing research on a long-duration space platform. The Phase 1 program was to provide to the US early experience prior to the construction and operation of the International Space Station (Phase 2 and 3). While it can be argued that Mir and ISS are different platforms and that programmatically Phase 1 and ISS are organized differently, it is also clear that many aspects of operating a long-duration research program are platform independent. This can be demonstrated by a review of lessons learned from Skylab, a US space station program of the mid-1970's, many of which were again "learned" on Mir and are being "learned" on ISS. Among these are optimum crew training strategies, on-orbit crew operations, ground support, medical operations and crew psychological support, and safety certification processes

    their work in Google Earth where they did a tour of their journey. In the feedback students said that it was a very interesting and an educational practical task. A new opportunity in M-learning is to use QR codes. This means that you don't have to print out worksheets with questions. You can hide question in the code and students can read them with their own devices on site. From the Master's thesis I also developed a tutorial material named "M-learning in a geography lesson" (in Estonian: M-õpe geograafiatunnis), you can see it in the webpage katrimope@wordpress.com. The tutorial received a second place on the Estonian study material contest in 2013. This is only one example on how to use M-learning. In Gustav Adolf Grammar School we use M-learning in lots of different subjects because it's really important in modern school to link new technologies, surrounding environment and learning for the purpose of better obtainment of knowledge.

    A workshop entitled "Lessons Learned from Radiation Oncology Trials" was held on December 7-8, 2011, in Bethesda, MD, to present and discuss some of the recently conducted radiation oncology clinical trials with a focus on those that failed to refute the null hypothesis. The objectives of this workshop were to summarize and examine the questions that these trials provoked, to assess the quality and limitations of the preclinical data that supported the hypotheses underlying these trials, and to consider possible solutions to these challenges for the design of future clinical trials. Several themes emerged from the discussions: (i) opportunities to learn from null-hypothesis trials through tissue and imaging studies; (ii) value of preclinical data supporting the design of combinatorial therapies; (iii) significance of validated biomarkers; (iv) necessity of quality assurance in radiotherapy delivery; (v) conduct of sufficiently powered studies to address the central hypotheses; and (vi) importance of publishing results of the trials regardless of the outcome. The fact that well-designed hypothesis-driven clinical trials produce null or negative results is expected given the limitations of trial design and complexities of cancer biology. It is important to understand the reasons underlying such null results, however, to effectively merge the technologic innovations with the rapidly evolving biology for maximal patient benefit through the design of future clinical trials.

    Native Navigators and the Cancer Continuum (NNACC) was a community-based participatory research study among five American Indian organizations. The intervention required lay Native Patient Navigators (NPNs) to implement and evaluate community education workshops in their local settings. Community education was a new role for the NPNs and resulted in many lessons learned. NPNs met quarterly from 2008 through 2013 and shared lessons learned with one another and with the administrative team. In July 2012, the NPNs prioritized lessons learned throughout the study that were specific to implementing the education intervention. These were shared to help other navigators who may be including community education within their scope of work. The NPNs identified eight lessons learned that can be divided into three categories: NPN education and training, workshop content and presentation, and workshop logistics and problem-solving. A ninth overarching lesson for the entire NNACC study identified meeting community needs as an avenue for success. This project was successful due to the diligence of the NPNs in understanding their communities' needs and striving to meet them through education workshops. Nine lessons were identified by the NPNs who provided community education through the NNACC project. Most are relevant to all patient navigators, regardless of patient population, who are incorporating public education into navigation services. Due to their intervention and budget implications, many of these lessons also are relevant to those who are developing navigation research. PMID:25087698

    The use of hyperspectral imagers to provide climate-quality data sets, such as those expected from the solar reflective sensor on the Climate Absolute Radiance and Refractivity Observatory (CLARREO), requires stringent radiometric calibration requirements. These stringent requirements have been nearly met with broadband radiometers such as CERES, but high resolution spectrometers pose additional challenges. A review of the calibration processes for past space-based HSIs provide guidance on the calibration processes that will be needed for future sensors. In November 2000, the Earth Observer-1 (EO-1) platform was launched onboard a Boeing Delta II launch vehicle. The primary purpose of the EO-1 mission was to provide a technological testbed for spaceborne components. The platform has three sensors onboard, of which, the hyperspectral imager (HSI) Hyperion, is discussed here. The Hyperion sensor at the time had no comparable sensor in earth orbit, being the first grating-based, hyperspectral, civilian sensor in earth orbit. Ground and on-orbit calibration procedures including all cross-calibration activities have achieved an estimated instrument absolute radiometric error of 2.9% in the Visible channel (0.4 - 1.0 microns) and 3.4% in the shortwave infrared (SWIR, 0.9 - 2.5 microns) channel (EO-1/Hyperion Early Orbit Checkout Report Part II On-Orbit Performance Verification and Calibration). This paper describes the key components of the Hyperion calibration process that are applicable to future HSI missions. The pre-launch methods relied on then newly-developed, detector-based methods. Subsequent vicarious methods including cross-calibration with other sensors and the reflectance-based method showed significant differences from the prelaunch calibration. Such a difference demonstrated the importance of the vicarious methods as well as pointing to areas for improvement in the prelaunch methods. We also identify areas where lessons learned from Hyperion regarding

    The Thomas Jefferson National Accelerator Facility is currently engaged in the 12 GeV Upgrade Project. The goal of the 12 GeV Upgrade is a doubling of the available beam energy of the Continuous Electron Beam Accelerator Facility (CEBAF) from 6 GeV to 12 GeV. This increase in beam energy will be due in large part to the addition of ten C100 cryomodules plus associated new RF in the CEBAF linacs. The C100 cryomodules are designed to deliver 100 MeV per installed cryomodule. Each C100 cryomodule is built around a string of eight seven-cell, electro-polished, superconducting RF cavities. While an average performance of 100MV per cryomodule is needed to achieve the overall 12 GeV beam energy goal, the actual performance goal for the cryomodules is an average energy gain of 108 MV to provide operational headroom. Cryomodule production started in December 2010. All ten of the C100 cryomodules are installed in the linac tunnels and are on schedule to complete commissioning by September 2013. Performance during Commissioning has ranged from 104 MV to 118 MV. In May, 2012 a test of an early C100 achieved 108 MV with full beam loading. This paper will discuss the performance of the C100 cryomodules along with operational challenges and lessons learned for future designs.

    The current task of Resource Allocation Process includes the planning and apportionment of JPL's Ground Data System composed of the Deep Space Network and Mission Control and Computing Center facilities. The addition of the data driven, rule based planning system, RALPH, has expanded the planning horizon from 8 weeks to 10 years and has resulted in large labor savings. Use of the system has also resulted in important improvements in science return through enhanced resource utilization. In addition, RALPH has been instrumental in supporting rapid turn around for an increased volume of special what if studies. The status of RALPH is briefly reviewed and important lessons learned from the creation of an highly functional design team are focused on through an evolutionary design and implementation period in which an AI shell was selected, prototyped, and ultimately abandoned, and through the fundamental changes to the very process that spawned the tool kit. Principal topics include proper integration of software tools within the planning environment, transition from prototype to delivered to delivered software, changes in the planning methodology as a result of evolving software capabilities and creation of the ability to develop and process generic requirements to allow planning flexibility.

  9. Contamination and UV lasers: lessons learned

    NASA Astrophysics Data System (ADS)

    Daly, John G.

    2015-09-01

    Laser induced damage to optical elements has been a subject of significant research, development, and improvement, since the first lasers were built over the last 50 years. Better materials, with less absorption, impurities, and defects are available, as well as surface coatings with higher laser damage resistance. However, the presence of contamination (particles, surface deposition films, or airborne) can reduce the threshold for damage by several orders of magnitude. A brief review of the anticipated laser energy levels for damage free operation is presented as a lead into the problems associated with contamination for ultraviolet (UV) laser systems. As UV lasers become more common in applications especially in areas such as lithography, these problems have limited reliability and added to costs. This has been characterized as Airborne Molecular Contamination (AMC) in many published reports. Normal engineering guidelines such as screening materials within the optical compartment for low outgassing levels is the first step. The use of the NASA outgassing database (or similar test methods) with low Total Mass Loss (TML) and Condensed Collected Volatiles Collected Mass (CVCM) is a good baseline. Energetic UV photons are capable of chemical bond scission and interaction with surface contaminant or airborne materials results in deposition of obscuring film laser footprints that continue to degrade laser system performance. Laser systems with average powers less than 5 mW have been shown to exhibit aggressive degradation. Lessons learned over the past 15 years with UV laser contamination and steps to reduce risk will be presented.

    As we consider the issues associated with the development of an Integrated Command Environment (ICE), we must obviously consider the rich history in the development of control rooms, operations centers, information centers, dispatch offices, and other command and control environments. This paper considers the historical perspective of control environments from the industrial revolution through the information revolution, and examines the historical influences and the implications that that has for us today. Environments to be considered are military command and control spaces, emergency response centers, medical response centers, nuclear reactor control rooms, and operations centers. Historical 'lessons learned' from the development and evolution of these environments will be examined to determine valuable models to use, and those to be avoided. What are the pitfalls? What are the assumptions that drive the environment design? Three case histories will be presented, examining (1) the control room of the Three Mile Island power plant, (2) the redesign of the US Naval Space Command operations center, and (3) a testbed for an ICE aboard a naval surface combatant.

  11. Protein Name Tagging Guidelines: Lessons Learned

    Hu, Zhangzhi; Jang, Seok Bae; Samuel, Ken; Krause, Matthew; Phillips, Jon; Wu, Cathy H.

    2005-01-01

    Interest in information extraction from the biomedical literature is motivated by the need to speed up the creation of structured databases representing the latest scientific knowledge about specific objects, such as proteins and genes. This paper addresses the issue of a lack of standard definition of the problem of protein name tagging. We describe the lessons learned in developing a set of guidelines and present the first set of inter-coder results, viewed as an upper bound on system performance. Problems coders face include: (a) the ambiguity of names that can refer to either genes or proteins; (b) the difficulty of getting the exact extents of long protein names; and (c) the complexity of the guidelines. These problems have been addressed in two ways: (a) defining the tagging targets as protein named entities used in the literature to describe proteins or protein-associated or -related objects, such as domains, pathways, expression or genes, and (b) using two types of tags, protein tags and long-form tags, with the latter being used to optionally extend the boundaries of the protein tag when the name boundary is difficult to determine. Inter-coder consistency across three annotators on protein tags on 300 MEDLINE abstracts is 0.868 F-measure. The guidelines and annotated datasets, along with automatic tools, are available for research use. PMID:18629297

    2013-01-01

    Periodontal diseases are initiated by bacterial species living in polymicrobial biofilms at or below the gingival margin and progress largely as a result of the inflammation initiated by specific subgingival species. In the past few decades, efforts to understand the microbiota of periodontal diseases have led to an exponential increase in information about biofilms associated with periodontal health and disease. In fact, the oral microbiota is one of the best characterized microbiomes that colonize the human body. Despite this increased knowledge, one has to ask if our fundamental concepts of the etiology and pathogenesis of periodontal diseases have really changed. In this chapter we will review how our comprehension of the structure and function of the subgingival microbiota evolved over the years in search of lessons learned and unlearned in periodontal microbiology. More specifically, this review focuses on: 1) how the data obtained through molecular techniques has impacted our knowledge of the etiology of periodontal infections; 2) the potential role of viruses in the etiopathogenesis of periodontal diseases; 3) how concepts of microbial ecology have expanded our understanding of host microbial interactions that might lead to periodontal diseases; 4) the role of inflammation in the pathogenesis of periodontal diseases; and 5) the impact of these evolving concepts on treatment and preventive approaches to periodontal infections. We will conclude by reviewing how novel systems biology approaches promise to unravel new details of the pathogenesis of periodontal diseases and, hopefully, lead to a better understanding of periodontal disease mechanisms.

    2004-10-01

    The far ultraviolet spectral region (roughly 900 - 1200 Å) is densely packed with strong atomic, ionic and molecular transitions of astrophysical importance. Many of these transitions provide unique access to the associated species. This spectral region is also technically challenging: optical reflectivities are limited, contamination control requirements are severe and detectors must be windowless. The Far Ultraviolet Spectroscopic Explorer (FUSE) covers the spectral region 905 -1187 Å with a resolution ~ 15 km s-1. The mission, launched in June 1999 and now in its fifth year of science operations, has reaped a rich scientific harvest from this spectral region. This paper will examine the lessons learned from the FUSE mission with the perspective of looking ahead to possible future missions. In order to build on the scientific advances of the FUSE mission, such a mission would require both increased sensitivity and higher spectral resolution. We conclude that achieving these requirements will necessitate, among other advances, new approaches to far ultraviolet mirror coating technology. We also examine the possibility of accessing the far ultraviolet using an ultraviolet observatory designed for longer wavelength ultraviolet radiation.

    1995-01-01

    As part of the Discovery Program's continuous improvement effort, a Discovery Program Lessons-Learned workshop was designed to review how well the Discovery Program is moving toward its goal of providing low-cost research opportunities to the planetary science community while ensuring continued U.S. leadership in solar system exploration. The principal focus of the workshop was on the recently completed Announcement of Opportunity (AO) cycle, but the program direction and program management were also open to comment. The objective of the workshop was to identify both the strengths and weaknesses of the process up to this point, with the goal of improving the process for the next AO cycle. The process for initializing the workshop was to solicit comments from the communities involved in the program and to use the feedback as the basis for establishing the workshop agenda. The following four sessions were developed after reviewing and synthesizing both the formal feedback received and informal feedback obtained during discussions with various participants: (1) Science and Return on Investment; (2) Technology vs. Risk; Mission Success and Other Factors; (3) Cost; and (4) AO.AO Process Changes and Program Management.

  15. Teaching with Internet Telescopes: Some Lessons Learned

    NASA Astrophysics Data System (ADS)

    Stencel, Robert

    Observational astronomy is often difficult for pre-college students and teachers because: (1) school occurs in daytime and visual observing at night; (2) light pollution hides the stars from students living in cities; (3) few schools have teachers trained to use and maintain astronomy equipment; (4) there is lack of access to expertise when needed; (5) physically disabled students cannot easily access a telescope eypiece. Internet access to computer controlled telescopes with digital cameras can solve many of these difficulties. The Web enables students and teachers to access well-maintained internet-controllable telescopes at dark-site locations and to consult more readily with experts. This paper reports on a three-month pilot project exploring this situation conducted Feb-May 2002 which allowed high school students to access a CCD-equipped accurately-pointing and tracking telescope located in New Mexico controllable over the Web with a user-friendly skymap browser tool. User interest proved phenomenal and user statistics proved diverse. There were distinct lessons learned about how to enhance student participation in the research process.

    2011-01-01

    Once a "Troubled Project" threatened with cancellation, the Stratospheric Observatory for Infrared Astronomy (SOFIA) Program has overcome many difficult challenges and recently achieved its first light images. To achieve success, SOFIA had to overcome significant deficiencies in fundamental Systems Engineering identified during a major Program restructuring. This presentation will summarize the lessons learn in Systems Engineering on the SOFIA Program. After the Program was reformulated, an initial assessment of Systems Engineering established the scope of the problem and helped to set a list of priorities that needed to be work. A revised Systems Engineering Management Plan (SEMP) was written to address the new Program structure and requirements established in the approved NPR7123.1A. An important result of the "Technical Planning" effort was the decision by the Program and Technical Leadership team to re-phasing the lifecycle into increments. The reformed SOFIA Program Office had to quickly develop and establish several new System Engineering core processes including; Requirements Management, Risk Management, Configuration Management and Data Management. Implementing these processes had to consider the physical and cultural diversity of the SOFIA Program team which includes two Projects spanning two NASA Centers, a major German partnership, and sub-contractors located across the United States and Europe. The SOFIA Program experience represents a creative approach to doing "System Engineering in the middle" while a Program is well established. Many challenges were identified and overcome. The SOFIA example demonstrates it is never too late to benefit from fixing deficiencies in the System Engineering processes.

    The National Compact Stellarator Experiment (NCSX) was designed to test physics principles of an innovative stellarator design developed by the Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory. Construction of some of the major components and sub-assemblies was completed, but the estimated cost and schedule for completing the project grew as the technical requirements and risks became better understood, leading to its cancellation in 2008. The project's risks stemmed from its technical challenges, primarily the complex component geometries and tight tolerances that were required. The initial baseline, established in 2004, was supported by a risk management plan and risk-based contingencies, both of which proved to be inadequate. Technical successes were achieved in the construction of challenging components and subassemblies, but cost and schedule growth was experienced. As part of an effort to improve project performance, a new risk management program was devised and implemented in 2007-08. It led to a better understanding of project risks, a sounder basis for contingency estimates, and improved management tools. Although the risks ultimately were unacceptable to the sponsor, valuable lessons in risk management were learned through the experiences with the NCSX project.

    This document (Volume I) provides an executive summary of the lessons learned from the Constellation Program. A companion Volume II provides more detailed analyses for those seeking further insight and information. In this volume, Section 1.0 introduces the approach in preparing and organizing the content to enable rapid assimilation of the lessons. Section 2.0 describes the contextual framework in which the Constellation Program was formulated and functioned that is necessary to understand most of the lessons. Context of a former program may seem irrelevant in the heady days of new program formulation. However, readers should take some time to understand the context. Many of the lessons would be different in a different context, so the reader should reflect on the similarities and differences in his or her current circumstances. Section 3.0 summarizes key findings developed from the significant lessons learned at the program level that appear in Section 4.0. Readers can use the key findings in Section 3.0 to peruse for particular topics, and will find more supporting detail and analyses in Section 4.0 in a topical format. Appendix A contains a white paper describing the Constellation Program formulation that may be of use to readers wanting more context or background information. The reader will no doubt recognize some very similar themes from previous lessons learned, blue-ribbon committee reviews, National Academy reviews, and advisory panel reviews for this and other large-scale human spaceflight programs; including Apollo, Space Shuttle, Shuttle/Mir, and the ISS. This could represent an inability to learn lessons from previous generations; however, it is more likely that similar challenges persist in the Agency structure and approach to program formulation, budget advocacy, and management. Perhaps the greatest value of these Constellation lessons learned can be found in viewing them in context with these previous efforts to guide and advise the Agency and its

These lessons are gleaned from our experiences developing, designing, building and testing the telescope and its subsystems, with 15 years of hindsight. Among the topics to be discussed are the early developmental tests, known as VETA-I and VETA-II, requirements derivation, the impact of late requirements and reflection on the conservatism in the design process. This poster offers some opinions on how these lessons can affect future missions.

  4. Natural Disasters: What Is Inside A Lesson Learned?

    The learning of lessons is something that is inherent to normal human behavior. All kind of human interaction experiences critical inspection after a severe or even disastrous event has occurred. Particular inspections have been undertaken in the field of natural disasters. Hence human risk management can continuously be improved according to lessons learned from previous disasters or with the outcome of experience shared with other stakeholders in that field. This paper shows the results of a lessons learned project over the past years: the NEDIES (Natural and Environmental Information Exchange System) deals with lessons learned during the classical risk management phases of prevention, preparedness and response At first glance a lesson is just pure text. Basically it mirrors what has been experienced within a certain context. Having a closer look at a lesson one finds out that a lesson refers to a specific emergency-triggering situation. A situation is more than a simple reference to a hazard: a "rapidly rising lake level" could have more meaning than "a flood". In order to take out positive information it is advisable not only to list up all potential benefits that could be drawn from a lesson; the explicit mentioning of benefits could be helpful in order to prepare further actions beforehand. Moreover one should also consider possible actions to take if that particular situation of the lesson exhibits again or elsewhere. In the case of rapidly rising lake level an a-priori prioritization of response actions could be done. The description of the situation is linked with other characteristics of the lesson; local issues as well as historical considerations can play a role. A flood in a densely populated town can produce different implications than a flood in the countryside. The benefits of the lesson and actions proposed could be linked with experiences made in the past. Other issues concern people involved: the addressees. Typical addressees are local decision

    Lessons learned are more in vogue today than at any time in our history. You can’t tune into a news broadcast without hearing a reference to the concept – and for good reason. People are finally accepting the idea that they may be able to benefit from the experiences of others. Corporations, government departments, and even the military are actively using lessons learned information to help them to achieve their varied goals. The Department of Energy is one of the government departments that has a Lessons Learned Program and requires its contractors to develop a program of their own. Unfortunately, adequate guidance is not available to enable contractors to design a fully mature program (i.e., a program that will immediately meet their every need) and to ensure that it is implemented such that it will be deemed acceptable during subsequent assessments. The purpose of this paper is to present the reader with information that might help him or her better plan and develop a new or upgraded Lessons Learned Program. The information is based on the actual development and implementation of a “second generation” lessons learned program and is presented as a chronicle of the steps taken to build the rudimentary system and the subsequent events and problems that led to the programs present-day configuration.

    Oracle WebDB is the easiest way to produce web enabled lightweight and enterprise-centric applications. This concept from Oracle has tantalized our taste for simplistic web development by using a purely web based tool that lives nowhere else but in the database. The use of online wizards, templates, and query builders, which produces PL/SQL behind the curtains, can be used straight ''out of the box'' by both novice and seasoned developers. The topic of this presentation will introduce lessons learned by developing and deploying applications built using the WebDB Component Builder in conjunction with custom PL/SQL code to empower a hybrid application. There are two kinds of WebDB components: those that display data to end users via reporting, and those that let end users update data in the database via entry forms. The presentation will also discuss various methods within the Component Builder to enhance the applications pushed to the desktop. The demonstrated example is an application entitled HOME (Helping Other's More Effectively) that was built to manage a yearly United Way Campaign effort. Our task was to build an end to end application which could manage approximately 900 non-profit agencies, an average of 4,100 individual contributions, and $1.2 million dollars. Using WebDB, the shell of the application was put together in a matter of a few weeks. However, we did encounter some hurdles that WebDB, in it's stage of infancy (v2.0), could not solve for us directly. Together with custom PL/SQL, WebDB's Component Builder became a powerful tool that enabled us to produce a very flexible hybrid application.

    The International Space Station ISS provides a variety of external research platforms for experiments aiming at the utilization of space parameters like vacuum, temperature oscillation and in particular extraterrestrial short wavelength UV and ionizing radiation which cannot be simulated accurately in the laboratory. Three Missions, two past and one upcoming, will be presented. A family of astrobiological experimental ESA facilities called "EXPOSE" were and will be accommodated on these outside exposure platforms: on one of the external balconies of the European Columbus Module (EXPOSE-E) and on the URM-D platform on the Russian Zvezda Module (EXPOSE-R and EXPOSE-R2). Exobiological and radiation experiments, exposing chemical, biological and dosimetric samples to the harsh space environment are - and will be - accommodated on these facilities to increase our knowledge on the origin, evolution and distribution of life, on Earth and possibly beyond. The biological experiments investigate resistance and adaptation of organisms like bacteria, Achaea, fungi, lichens, plant seeds and small animals like mosquito larvae to extreme environmental conditions and underlying mechanisms like DNA repair. The organic chemical experiments analyse chemical reactions triggered by the extraterrestrial environment, especially short wavelength UV radiation, to better understand prebiotic chemistry. The facility is optimized to allow exposure of biological specimen and material samples under a variety of conditions, using optical filter systems. Environmental parameters like temperature and radiation are regularly recorded and down linked by telemetry. Two long term missions named according to their facility - EXPOSE-E and EXPOSE-R - are completed and a third mission is planned and currently prepared. Operations of all three missions including sample accommodation are performed by DLR. An overview of the two completed missions will be given including lessons learned as well as an outlook

    Lessons learned from the design and operation of the Integrated Topping Cycle MHD generator are presented. This generator is part of a 50 MWt prototypic powertrain which recently completed proof-of-concept testing at the U.S. Department of Energy`s Component Development and Integration Facility. Duration testing was performed at conditions representative of future commercial MHD power plant operation in order to establish component lifetimes and to verify the design performance parameters. Over 500 cumulative hours of thermal and power tests were obtained with the generator hardware before the program was terminated. This paper summarizes the various lessons learned during the design and operation of the prototypic MHD power generator. Worthwhile features that should be adopted in future generator designs are discussed, as well as things one would do differently. Some issues remain unresolved at the conclusion of the test program; these are also summarized.

Throughout this process, the X-37 Project team captures lessons that are directly applicable to other such efforts. The upcoming ALTV flights offer another dimension of data and first-hand experience that will prove invaluable to those designing new generations of reusable spacecraft. And ongoing technology developments will expand the aerospace knowledge base. Delivering prototype hardware is always a risky proposition. During the course of the X-37 effort, the team has experienced many challenging opportunities, delivering significant accomplishments and learning numerous lessons in the process. The ability to manage the risk landscape is key to overcoming obstacles, especially technical hurdles that are encountered in progressing hardware from design to flight. The approach to managing risk under this partnership is evolving but, in general, the team allocates resources to reduce the likelihood of severe-consequence risks, thus maximizing mission success and ensuring that the X-37 Project delivers value to its stakeholders. As the team sharpens its focus on operations, it continues to contribute knowledge to those who would undertake high-risk, high-payoff research and development and provides valuable experience to implement the exploration vision.

    A suite of 18 computer-assisted learning (C.A.L.) lessons has been developed in drug disposition covering processes, concepts and techniques, and pharmacokinetics. Development of lesions and implementation (using CDC's PLATO Programmerless Courseware Development authoring language (Advanced Tutorial Model) for delivery on IBM-PC clones (some also using NPL's Microtext on BBC model B microcomputers) and evaluation by questionnaire proceeded in stages. Staff assessed the authoring system and library lessons for their potential usefulness. Students assessed the importance to their own learning of the features that good quality C.A.L. lessons should display. Finally, our lessons were assessed by students for the presence of these features, comparison with other forms of presentation, their teaching performance, and integration into the curriculum. The use of a programmerless authoring language allowed the authors to concentrate on lesson subject content. The students appreciated the ability to go at their own pace and that their active involvement was required. Lessons scored well in relation to private reading and lectures but less well in comparison with practical work and tutorials. Appropriate integration of C.A.L. into the curriculum was found to be important. Evaluation by questionnaire at each stage of development was valuable. PMID:3065577

    Rationale Paper-based medical record systems are known to have major problems of inaccuracy, incomplete data, poor accessibility, and challenges to patient confidentiality. They are also an inefficient mechanism of record-sharing for interdisciplinary patient assessment and management, and represent a major problem for keeping current and monitoring quality control to facilitate improvement. To address those concerns, national, regional, and local health care authorities have increased the pressure on oncology practices to upgrade from paper-based systems to electronic health records. Objectives Here, we describe and discuss the challenges to implementing a region-wide oncology information system across four independent health care organizations, and we describe the lessons learned from the initial phases that are now being applied in subsequent activities of this complex project. Results The need for change must be shared across centres to increase buy-in, adoption, and implementation. It is essential to establish physician leadership, commitment, and engagement in the process. Work processes had to be revised to optimize use of the new system. Culture change must be included in the change management strategy. Furthermore, training and resource requirements must be thoroughly planned, implemented, monitored, and modified as required for effective adoption of new work processes and technology. Interfaces must be established with multiple existing electronic systems across the region to ensure appropriate patient flow. Periodic assessment of the existing project structure is necessary, and adjustments are often required to ensure that the project meets its objectives. Conclusions The implementation of region-wide oncology information systems across different health practice locations has many challenges. Leadership is essential. A strong, collaborative information-sharing strategy across the region and with the supplier is essential to identify, discuss, and resolve

    Gerber, M.S.

    1996-09-19

    accompanied by and were an integral part of sweeping ``culture changes,`` the story of the lessons learned during the PUREX Deactivation Project are worth recounting. Foremost among the lessons is recognizing the benefits of ``right to left`` project planning. A deactivation project must start by identifying its end points, then make every task, budget, and organizational decision based on reaching those end points. Along with this key lesson is the knowledge that project planning and scheduling should be tied directly to costing, and the project status should be checked often (more often than needed to meet mandated reporting requirements) to reflect real-time work. People working on a successful project should never be guessing about its schedule or living with a paper schedule that does not represent the actual state of work. Other salient lessons were learned in the PUREX/UO3 Deactivation Project that support these guiding principles. They include recognizing the value of independent review, teamwork, and reengineering concepts; the need and value of cooperation between the DOE, its contractors, regulators, and stakeholders; and the essential nature of early and ongoing communication. Managing a successful project also requires being willing to take a fresh look at safety requirements and to apply them in a streamlined and sensible manner to deactivating facilities; draw on the enormous value of resident knowledge acquired by people over years and sometimes decades of working in old plants; and recognize the value of bringing in outside expertise for certain specialized tasks.This approach makes possible discovering the savings that can come when many creative options are pursued persistently and the wisdom of leaving some decisions to the future. The essential job of a deactivation project is to place a facility in a safe, stable, low-maintenance mode, for an interim period. Specific end points are identified to recognize and document this state. Keeping the limited

    During the period from 1977 to 1989, the Lawrence Livermore National Laboratory (LLNL) conducted a liquefied gaseous fuels spill effects program under the sponsorship of the US Department of Energy, Department of Transportation, Gas Research Institute and others. The goal of this program was to develop and validate tools that could be used to predict the effects of a large liquefied gas spill through the execution of large scale field experiments and the development of computer models to make predictions for conditions under which tests could not be performed. Over the course of the program, three series of LNG spill experiments were performed to study cloud formation, dispersion, combustion and rapid phase transition (RPT) explosions. The purpose of this paper is to provide an overview of this program, the lessons learned from 12 years of research as well as some recommendations for the future. The general conclusion from this program is that cold, dense gas related phenomena can dominate the dispersion of a large volume, high release rate spill of LNG especially under low ambient wind speed and stable atmospheric conditions, and therefore, it is necessary to include a detailed and validated description of these phenomena in computer models to adequately predict the consequences of a release. Specific conclusions include: * LNG vapor clouds are lower and wider than trace gas clouds and tend to follow the downhill slope of terrain due to dampened vertical turbulence and gravity flow within the cloud. Under low wind speed, stable atmospheric conditions, a bifurcated, two lobed structure develops. * Navier-Stokes models provide the most complete description of LNG dispersion, while more highly parameterized Lagrangian models were found to be well suited to emergency response applications. * The measured heat flux from LNG vapor cloud burns exceeded levels necessary for third degree burns and were large enough to ignite most flammable materials. * RPTs are of two

    2006-01-01

    Experience on International Space Station (ISS) provides many important lessons for future space flight. NASA human factors engineers have been systematically collecting lessons learned from crew debriefs, as well as working with ground support teams to continuously improve crew operations. This paper describes the methods for collecting data from debriefs, lessons learned through that process, and an example of a technology development task funded through the Space Human Factors Engineering (SHFE) program element in response to an identified operational need. Each ISS increment crew spends many hours after the flight answering questions from the various subsystem leads. The Flight Crew Integration subsystem lead asks questions specific to human factors and habitability issues. In addition, crew comments on many other subsystems provide insight into interface designs, operability and maintainability. The debrief comments are unique to each crew, and must be categorized to provide operational lessons learned. Personal identifiers are removed and comments aggregated to separate consistent issues from personal preferences. Examples will be given, and the procedure for incorporating the lessons into requirements and guidelines for the next human space vehicle will be described. In flight, very few astronauts are medical doctors. Written medical procedures during flight need to be easy to follow and quick to understand. The problem was analyzed as part of a SHFE task. Organization was analyzed and reorganizations were created and tested. Results will be reported. The ISS is a very important analog for planning future long-term missions. Collection of data from debriefs, studying the lessons learned and focusing on requirements for future missions are examples of the accomplishments through the SHFE program.

  10. Crew Survival Lessons Learned from the Columbia Mishap

    NASA Astrophysics Data System (ADS)

    Clark, J. B.

    Spacecraft mishaps involving loss of life are fortunately relatively rare. They always offer tremendous insight into improve- ments in vehicle design and operations. Aeromedical forensic analysis is a vital aspect of every aviation mishap, yet its application in spacecraft mishap investigation seems elusive. Due to the sensitive nature of fatal spacecraft accidents, analysis of human factors and forensics may not always be available for future vehicle designers. The occupant protection and crew survival lessons learned are a vital part of any mishap, and particularly spacecraft mishaps. This article will address crew survival lessons from the Columbia mishap and how they apply to future spacecraft design.

  14. Lift-fan aircraft: Lessons learned-the pilot's perspective

    NASA Technical Reports Server (NTRS)

    Gerdes, Ronald M.

    1993-01-01

    This paper is written from an engineering test pilot's point of view. Its purpose is to present lift-fan 'lessons learned' from the perspective of first-hand experience accumulated during the period 1962 through 1988 while flight testing vertical/short take-off and landing (V/STOL) experimental aircraft and evaluating piloted engineering simulations of promising V/STOL concepts. Specifically, the scope of the discussions to follow is primarily based upon a critical review of the writer's personal accounts of 30 hours of XV-5A/B and 2 hours of X-14A flight testing as well as a limited simulator evaluation of the Grumman Design 755 lift-fan aircraft. Opinions of other test pilots who flew these aircraft and the aircraft simulator are also included and supplement the writer's comments. Furthermore, the lessons learned are presented from the perspective of the writer's flying experience: 10,000 hours in 100 fixed- and rotary-wing aircraft including 330 hours in 5 experimental V/STOL research aircraft. The paper is organized to present to the reader a clear picture of lift-fan lessons learned from three distinct points of view in order to facilitate application of the lesson principles to future designs. Lessons learned are first discussed with respect to case histories of specific flight and simulator investigations. These principles are then organized and restated with respect to four selected design criteria categories in Appendix I. Lastly, Appendix Il is a discussion of the design of a hypothetical supersonic short take-off vertical landing (STOVL) fighter/attack aircraft.

    PubMed Central

    Abramson, Charles I.; Chicas-Mosier, Ana M.

    2016-01-01

    This article provides an overview of the early Mimosa pudica literature; much of which is in journals not easily accessible to the reader. In contrast to the contemporary plant learning literature which is conducted primarily by plant biologists, this early literature was conducted by comparative psychologists whose goal was to search for the generality of learning phenomena such as habituation, and classical conditioning using experimental designs based on animal conditioning studies. In addition to reviewing the early literature, we hope to encourage collaborations between plant biologists and comparative psychologists by familiarizing the reader with issues in the study of learning faced by those working with animals. These issues include no consistent definition of learning phenomena and an overreliance on the use of cognition. We suggested that greater collaborative efforts be made between plant biologists and comparative psychologists if the study of plant learning is to be fully intergraded into the mainstream behavior theory.

  10. Lessons to be learned from Pierre Fauchard.

    PubMed

    Garant, P R

    1990-01-01

    Pierre Fauchard possessed the following attributes: Curiosity, intelligence, courage, perseverance, honesty, dexterity, and social responsibility. I suspect that these qualities would have assured him success in whatever career he might have followed. He chose surgery, and through his experience as a ship's doctor in the French navy, he specialized in diseases of the mouth and teeth (common among seamen), qualifying as a surgeon-dentist prior to establishing his highly successful private practice in Paris. In his long career he stood for excellence, the scientific approach, comprehensive care, high ethical standards, and technical innovation. Although we know almost nothing of his private life, his book does reveal a good part of his character. Based solely on this source it is possible to conclude that Fauchard was a true son of the enlightenment, who justifiably holds the title of Father of Modern Dentistry. His treatise contains lessons to be emulated even into the 21st century. PMID:2254534

    PubMed

    Sullivan-Marx, Eileen M

    2008-05-01

    For more than 25 years, advanced practice nurses have been incrementally included as a part of the health care financing structure. Following physician payment revisions at the federal level, advanced practice nurses were overtly recognized as Medicare providers and have participated in the establishment of current procedural terminology codes and the subsequent relative work values associated with payment. Success in this regard has been the result of business, political, and policy savvy that has important lessons for moving forward in any health care restructuring for both nurses and advanced practice nurses. Principles of valuing nurse work, time, and intensity in the Resource-Based Relative Value Scale are discussed with implications for future opportunities of measuring nursing work and any potential relationship to quality outcomes of care.

  12. Lessons learned -- NREL Village Power Program

    SciTech Connect

    Flowers, L.

    1998-07-01

    In 1993, a workshop was convened at the National Renewable Energy Laboratory (NREL) to discuss the issues of applying renewable energy in a sustainable manner to international rural development. One of the summary recommendations was that NREL could assist in the renewable energy for rural electrification effort by developing and supplying six related activities: resource assessment, comparative analysis and modeling, performance monitoring and analysis, pilot project development, internet-based project data, communications, and training. In response to this recommendation, NREL launched its Village Power Program consisting of these activities that cut across NREL technologies and disciplines. Currently NREL is active in 20 countries, with pilot projects in 12 of those countries. At this time the technologies include photovoltaics, wind, biomass, and hybrids. The rural applications include home lighting and communications, water pumping, schools and health posts, battery charging stations, ecotourism, and village systems. These pilot projects are central to the renewable energy village power development through the demonstration of three aspects critical to replication and implementation of the projects on a significant scale. The three aspects are technical functionality, economic competitiveness, and institutional sustainability. It is important to note that the pilot projects from which NREL's experience has been gained were funded and, in many cases, developed by other organizations and agencies. NREL's role has been one of technical assistance or project management or both. The purpose of this paper is to describe the lessons NREL staff has gleaned from their participation in the various pilot projects. The author hopes that these lessons will help the Renewable Energy-Based Rural Electrification (RERE) community in implementing sustainable projects that lead to replication.

  13. Scheduling lessons learned from the Autonomous Power System

    NASA Technical Reports Server (NTRS)

    Ringer, Mark J.

    1992-01-01

    The Autonomous Power System (APS) project at NASA LeRC is designed to demonstrate the applications of integrated intelligent diagnosis, control, and scheduling techniques to space power distribution systems. The project consists of three elements: the Autonomous Power Expert System (APEX) for Fault Diagnosis, Isolation, and Recovery (FDIR); the Autonomous Intelligent Power Scheduler (AIPS) to efficiently assign activities start times and resources; and power hardware (Brassboard) to emulate a space-based power system. The AIPS scheduler was tested within the APS system. This scheduler is able to efficiently assign available power to the requesting activities and share this information with other software agents within the APS system in order to implement the generated schedule. The AIPS scheduler is also able to cooperatively recover from fault situations by rescheduling the affected loads on the Brassboard in conjunction with the APEX FDIR system. AIPS served as a learning tool and an initial scheduling testbed for the integration of FDIR and automated scheduling systems. Many lessons were learned from the AIPS scheduler and are now being integrated into a new scheduler called SCRAP (Scheduler for Continuous Resource Allocation and Planning). This paper will service three purposes: an overview of the AIPS implementation, lessons learned from the AIPS scheduler, and a brief section on how these lessons are being applied to the new SCRAP scheduler.

  17. Developing materials to promote inquiry: Lessons learned

    NASA Astrophysics Data System (ADS)

    Trumbull, Deborah J.; Bonney, Rick; Grudens-Schuck, Nancy

    2005-11-01

    This paper focuses on an early stage of developing curricular materials to support students' learning of scientific inquiry. The materials being developed and tested, called Classroom FeederWatch (CFW), aimed to support science inquiry and were developed by a collaborative team of private curriculum developers and scientists (ornithologists). Inquiry dimensions were influenced at the outset by the newly released National Science Education Standards (National Research Council, Washington, DC: National Academy Press, 1996) and by prior successful experiences of ornithologists with inquiry experiences for adults. Despite hopes that CFW materials would assist middle school students to learn inquiry, evaluation findings showed little increase in students' understanding of inquiry or the ability to plan and conduct inquiry. We learned that improvements to inquiry dimensions of the curriculum required aligning activities more closely with practices that reflected the work of scientists in the discipline, integrating learning of content knowledge with learning about inquiry, and adjusting evaluation protocols to more accurately assess inquiry as represented in the Standards. Discussion highlights the influence of the Standards on development of inquiry dimensions of the materials, including the way in which initial application of the Standards to the early version of CFW materials may have restricted the engagement of both students and teachers in conducting science inquiry.

    Zhang, Junfeng Jim; Samet, Jonathan M

    2015-01-01

    Air pollution in many Chinese cities has been so severe in recent years that a special terminology, the "Chinese haze", was created to describe China's air quality problem. Historically, the problem of Chinese haze has developed several decades after Western high-income countries have significantly improved their air quality from the smog-laden days in the early- and mid-20(th) century. Hence it is important to provide a global and historical perspective to help China combat the current air pollution problems. In this regard, this article addresses the followings specific questions: (I) What is the Chinese haze in comparison with the sulfurous (London-type) smog and the photochemical (Los Angeles-type) smog? (II) How does Chinese haze fit into the current trend of global air pollution transition? (III) What are the major mitigation measures that have improved air quality in Western countries? and (IV) What specific recommendations for China can be derived from lessons and experiences from Western countries?

    Two years into its development, the VSO has emerged from a drawing board concept into a full-fledged data query and data delivery system serving the Solar Physics community. Throughout its development, the VSO has lived up to its `small box' motto and has built light-weight servers that can easily run on a desktop or laptop. The two basic functions of the VSO are data query and data delivery. For these functions, the VSO servers act like switchboards, dispatching query/data requests to relevant data providers. More important, these servers present an abstraction that integrates diverse data archives, thus reducing complexity. The design of the VSO has evolved during its implementation in response to difficulties and user feedback. We discuss the changes in areas such as the data model, user interface, and performance. These lessons should be of interest to people designing and building other virtual observatories. We also discuss challenges and opportunities we foresee as the VSO becomes a significant and enabling research tool.

    2008-08-20

    Light emitting diode (LED) technology has emerged as an exciting new lighting alternative with the potential for significant energy savings. There is concern, however, that white light LEDs for general illumination could take a long, bumpy course similar to another energy-efficient lighting technology – compact fluorescent lights (CFLs). Recognizing the significant potential energy-efficient lighting has to reduce U.S. energy consumption, Congress mandated in the Energy Policy Act of 2005 that the U.S. Department of Energy (DOE) develop Solid State Lighting (SSL) through a Next Generation Lighting Initiative. DOE’s first step was to analyze the market introduction of compact fluorescent lighting to determine what lessons could be learned to smooth the introduction of SSL in the United States (Sandahl et al. 2006). This paper summarizes applicable lessons learned from the market introduction of CFLs and describe how DOE and others are applying those lessons to speed the development and market introduction of energy-efficient LED lighting for general illumination applications. A description of the current state of LED technology and compares LEDs to incandescent, fluorescent, and halogen lights is also provided.

    This perspective paper reviews progress made in the last decades to enhance the communication and use of climate information relevant to the political and economic decision process. It focuses, specifically, on the creation and development of climate services, and highlights a number of difficulties that have limited the success of these services. Among them are the insufficient awareness by societal actors of their vulnerability to climate change, the lack of relevant products and services offered by the scientific community, the inappropriate format in which the information is provided, and the inadequate business model adopted by climate services. The authors suggest that, to be effective, centers should host within the same center a diversity of staff including experts in climate science, specialists in impact, adaptation, and vulnerability, representatives of the corporate world, agents of the public service as well as social managers and communication specialists. The role and importance of environmental engineering is emphasized.

  5. Oil field redevelopment -- some lessons learned

    SciTech Connect

    Robertson, M.

    1996-12-31

    This paper presents a summary of some oil field redevelopment experiences that resulted in unanticipated expenses or other inconveniences and consequently became learning experiences. Compared with many other types of contaminated properties, oil fields are relatively easy to remediate. The primary contaminant is crude oil ranging in nature from hard and weathered tar to fresh crude with a notable fraction of light end hydrocarbons. Groundwater is usually not impacted due to the low mobility and solubility of crude oil. Crude oil overall has a relatively low toxicity, is not considered a hazardous material and can usually be easily remediated using bioremediation. All of these factors contribute to the notion that oil fields are low risk in terms of cleanup. However, experience has shown that oil field redevelopment does have some risks as is illustrated by examples.

  6. Lessons Learned in Student Venture Creation

    NASA Astrophysics Data System (ADS)

    Caner, Edward

    The Physics Entrepreneurship Master's Program (PEP) at Case Western Reserve University is now in its 15th year of operation. PEP is a 27 credit-hour Master of Science in Physics, Entrepreneurship Track. The curriculum can be tailored to the needs of each student. Coursework consists of graduate-level classes in science, business, intellectual property law, and innovation. A master's thesis is required that is based on a real-world project in innovation or entrepreneurship within an existing company or startup (possibly the student's). PEP faculty help students connect with mentors, advisors, partners, funding sources and job opportunities. In this talk I will chronicle several pitfalls that we have encountered with our ''real world'' student projects and start-up businesses, several of which met their complete demise despite showing great promise for success. I will discuss how we have learned to avoid most of these pitfalls by taking surprisingly simple actions.

  7. University / Science Center Exhibit Development Collaboration: Strategies and Lessons Learned

    2008-06-01

    Through funding from the NSF's Internship in Public Science Education (IPSE) program, Johns Hopkins University (JHU) and the Maryland Science Center (MSC) have worked together to create an exhibit based on JHU's research with the Sloan Digital Sky Survey, a project to map the universe. The exhibit is a kiosk-based interactive presentation that connects to online data about the sky. It is currently displayed in SpaceLink, an area at the MSC that focuses on current events and research in astronomy. The person primarily responsible for the exhibit was a graduate student in computer science in the JHU Physics and Astronomy department. He worked with an EPO professional in the department and two members of the MSC's planetarium and exhibit staff to plan the exhibit. The team also worked with a coordinator in the JHU chemistry department, and an external evaluator. Along with increased public understanding of science, our goal was to create and evaluate a sustainable partnership between a research university and a local science center. We are producing an evaluation report discussing our collaboration and detailing lessons learned. We hope that our experience can be a model for other university / science center collaborations in the future. Some lessons that we have learned in our development effort are: start all design decisions with learning goals and objectives, write goals with evaluation in mind, focus on the process of science, and do not underestimate the challenges of working with the web as part of the exhibit technology.

    Introduction The field of public health is increasingly implementing initiatives intended to make policies, systems, and environments (PSEs) more supportive of healthy behaviors, even though the evidence for many of these strategies is only emerging. Our objective was 3-fold: 1) to describe evaluations of PSE-change programs in which the evaluators followed the steps of the Centers for Disease Control and Prevention’s (CDC’s) Framework for Program Evaluation in Public Health, 2) to share the resulting lessons learned, and 3) to assist future evaluators of PSE-change programs with their evaluation design decisions. Methods Seven Prevention Research Centers (PRCs) applied CDC’s framework to evaluate their own PSE-change initiatives. The PRCs followed each step of the framework: 1) engage stakeholders, 2) describe program, 3) focus evaluation design, 4) gather credible evidence, 5) justify conclusions, and 6) ensure use and share lessons learned. Results Evaluation stakeholders represented a range of sectors, including public health departments, partner organizations, and community members. Public health departments were the primary stakeholders for 4 of the 7 evaluations. Four PRCs used logic models to describe the initiatives being evaluated. Their evaluations typically included both process and outcome questions and used mixed methods. Evaluation findings most commonly focused on contextual factors influencing change (process) and the adoption or implementation of PSE-change strategies (outcome). Evaluators shared lessons learned through various channels to reach local stakeholders and broader public health audiences. Conclusion Framework for Program Evaluation in Public Health is applicable to evaluations of PSE-change initiatives. Using this framework to guide such evaluations builds practice-based evidence for strategies that are increasingly being used to promote healthful behaviors. PMID:26469947

    Computational modeling using boundary element techniques has been proposed for design and evaluation of shipboard impressed current cathodic protection (ICCP) systems. LaPlace's equation, the governing differential equation for electrochemical corrosion, is well suited for solution by the boundary element method. There has been much work performed in this field during the past two decades. Computational modeling efforts designed to validate boundary element procedures are reviewed. US Navy ship systems discussed are CG-59, CG-66, and CVN-068. Computational analysis accuracy is determined by comparison with physical scale modeling experimental results. Lessons learned from the analysis described are summarized. Advantages and disadvantages of boundary element modeling are discussed.

    The Stardust-NExT (New Exploration of Tempel) mission, a follow-on to the Stardust prime mission, successfully completed a flyby of comet Tempel-1 on 2/14/11. However there were many challenges along the way, most significantly low propellant margin and detection of the comet in imagery later than antici-pated. These challenges and their ramifications forced the project to respond with flexibility and ingenuity. As a result, the flyby at an altitude of 178 km was nearly flawless, accomplishing all its science objectives. Lessons learned on Stardust-NExT may have relevance to other spacecraft missions.

    Reducing spacecraft ground system operations costs is a major goal in all missions. The Fast Auroral Snapshot (FAST) flight operations team at the NASA/Goddard Spacecraft Flight Center developed in-house scripts and procedures to automate monitoring of critical spacecraft functions. The initial staffing profile of 16x7 was reduced first to 8x5 and then to 'lights out'. Operations functions became an offline review of system performance and the generation of future science plans for subsequent upload to the spacecraft. Lessons learned will be applied to the challenging Triana mission, where 24x7 contact with the spacecraft will be necessary at all times.

    Today, elliptical superconducting RF (SRF) cavities are preferably made from deep-drawn niobium sheets as pursued at Jefferson Laboratory (JLab). The fabrication of a cavity incorporates various cavity cell machining, trimming and electron beam welding (EBW) steps as well as surface chemistry that add to forming errors creating geometrical deviations of the cavity shape from its design. An analysis of in-house built cavities over the last years revealed significant errors in cavity production. Past fabrication flaws are described and lessons learned applied successfully to the most recent in-house series production of multi-cell cavities.

    1988-01-01

    Two troublesome, torque related problems associated with gimbal actuators are discussed. Large, thin section angular contact bearings can have a surprisingly high torque sensitivity to radial thermal gradients. A predictive thermal-mechanical bearing analysis, as described, was helpful in establishing a safe temperature operating envelope. In the second example, end-of-travel torque limits of an oscillatory gimbal bearing appoached motor stall during limit cycling life tests. Bearing modifications required to restore acceptable torque performance are described. The lessons learned from these case studies should benefit designers of precision gimbals where singular bearing torque related problems are not uncommon.

    1999-01-01

    The International Space Station has been in development since 1984, and has recently begun on orbit assembly. Most of the hardware for the Space Station has been manufactured and the rest is well along in design. The major sets of hardware that are still to be developed for Space Station are the pallets and interfacing hardware for resupply of unpressurized spares and scientific payloads. Over the last ten years, there have been numerous starts, stops, difficulties and challenges encountered in this effort. The Space Station program is now entering the beginning of orbital operations. The Program is only now addressing plans to design and build the carriers that will be needed to carry the unpressurized cargo for the Space Station lifetime. Unpressurized carrier development has been stalled due to a broad range of problems that occurred over the years. These problems were not in any single area, but encompassed budgetary, programmatic, and technical difficulties. Some lessons of hindsight can be applied to developing carriers for the Space Station. Space Station teams are now attempting to incorporate the knowledge gained into the current development efforts for external carriers. In some cases, the impacts of these lessons are unrecoverable for Space Station, but can and should be applied to future programs. This paper examines the progress and problems to date with unpressurized carrier development identifies the lessons to be learned, and charts the course for finally accomplishing the delivery of these critical hardware sets.

    2014-01-01

    Background and objective Intermountain Healthcare has a long history of using coded terminology and detailed clinical models (DCMs) to govern storage of clinical data to facilitate decision support and semantic interoperability. The latest iteration of DCMs at Intermountain is called the clinical element model (CEM). We describe the lessons learned from our CEM efforts with regard to subjective decisions a modeler frequently needs to make in creating a CEM. We present insights and guidelines, but also describe situations in which use cases conflict with the guidelines. We propose strategies that can help reconcile the conflicts. The hope is that these lessons will be helpful to others who are developing and maintaining DCMs in order to promote sharing and interoperability. Methods We have used the Clinical Element Modeling Language (CEML) to author approximately 5000 CEMs. Results Based on our experience, we have formulated guidelines to lead our modelers through the subjective decisions they need to make when authoring models. Reported here are guidelines regarding precoordination/postcoordination, dividing content between the model and the terminology, modeling logical attributes, and creating iso-semantic models. We place our lessons in context, exploring the potential benefits of an implementation layer, an iso-semantic modeling framework, and ontologic technologies. Conclusions We assert that detailed clinical models can advance interoperability and sharing, and that our guidelines, an implementation layer, and an iso-semantic framework will support our progress toward that goal.

    2005-01-01

    Two qualitative case studies focus on the allocation of CDC funds distributed during 2002 for bioterrorism preparedness in two Texas public health regions (each as populous and complex as many states). Lessons learned are presented for public health officials and others who work to build essential public health services and security for our nation. The first lesson is that personal relationships are the cornerstone of preparedness. A major lesson is that a regional strategy to manage funds may be more effective than allocating funds on a per capita basis. One regional director required every local department to complete a strategic plan as a basis for proportional allocation of the funds. Control of communicable diseases was a central component of the planning. Some funds were kept at the regional level to provide epidemiology services, computer software, equipment, and training for the entire region. Confirmation of the value of this regional strategy was expressed by local public health and emergency management officials in a focus group 1 year after the strategy had been implemented. The group members also pointed out the need to streamline the planning process, provide up-to-date computer networks, and receive more than minimal communication. This regional strategy can be viewed from the perspective of adaptive leadership, defined as activities to bring about constructive change, which also can be used to analyze other difficult areas of preparedness.

    Scientific software has become an indispensable commodity for the production, processing and analysis of empirical data but also for modelling and simulation of complex processes. Software has a significant influence on the quality of research results. For strengthening the recognition of the academic performance of scientific software development, for increasing its visibility and for promoting the reproducibility of research results, concepts for the publication of scientific software have to be developed, tested, evaluated, and then transferred into operations. For this, the publication and citability of scientific software have to fulfil scientific criteria by means of defined processes and the use of persistent identifiers, similar to data publications. The SciForge project is addressing these challenges. Based on interviews a blueprint for a scientific software publishing platform and a systematic implementation plan has been designed. In addition, the potential of journals, software repositories and persistent identifiers have been evaluated to improve the publication and dissemination of reusable software solutions. It is important that procedures for publishing software as well as methods and tools for software engineering are reflected in the architecture of the platform, in order to improve the quality of the software and the results of research. In addition, it is necessary to work continuously on improving specific conditions that promote the adoption and sustainable utilization of scientific software publications. Among others, this would include policies for the development and publication of scientific software in the institutions but also policies for establishing the necessary competencies and skills of scientists and IT personnel. To implement the concepts developed in SciForge a combined bottom-up / top-down approach is considered that will be implemented in parallel in different scientific domains, e.g. in earth sciences, climate research and

    A comprehensive database of engineering lessons learned that corresponds with relevant technical standards will be a valuable asset to those engaged in studies on future space vehicle developments, especially for structures, materials, propulsion, control, operations and associated elements. In addition, this will enable the capturing of technology developments applicable to the design, development, and operation of future space vehicles as planned in the Space Launch Initiative. Using the time-honored tradition of passing on lessons learned while utilizing the newest information technology, NASA has launched an intensive effort to link lessons learned acquired through various Internet databases with applicable technical standards. This paper will discuss the importance of lessons learned, the difficulty in finding relevant lessons learned while engaged in a space vehicle development, and the new NASA effort to relate them to technical standards that can help alleviate this difficulty.

  20. The teaching learning collaborative's influence on lesson plans

    NASA Astrophysics Data System (ADS)

    De La Riva, Yanette

    With a growing population of English Language Learners in our schools, their specialized classroom needs must be addressed. California state testing shows that English Language Learners (ELL) consistently perform below proficiency as compared to other students who are not English Language Learners. Many times, in response to pressure placed by the state testing requirements, administrators and educators focus on English Language development strategies at the cost of other content areas such as science. The Science and English Learning Development Blended Program is a professional development project that combines English Language Development (ELD) strategies within science lesson plans to address the language needs of English Language Learners through science content. The Blended Program was in place for four years in an urban school district in southern California. During its initial year of implementation, a research study focused on the types of changes teachers made to their science lesson plans as a result of their professional development: all of the changes made had to do with English Language Development and not Science. Implications of this study suggest that at the start of the program changes to support science content were not made because the teachers did not have the science knowledge to be comfortable enough to make changes to address the science portion of the lesson. The data analyzed for this study was collected during the Blended Program's third and fourth year of implementation. The findings show changes which reflect the following themes: science concept acquisition, oral language development, and scaffolding instruction. These themes reflect changes . that address both English Language Development and science. The individuals involved with the Blended Program have now had training for ELD and Science content for three or four years. Results suggest that the training not only equipped the teachers with English Language Development strategies

    Planning products and procedures that allowed the mission Flight Control Teams and the Astronaut crews to plan, train and fly every Space Shuttle mission were developed by the Flight Planning Branch at the NASA Johnson Space Center in Houston, Texas. As the Space Shuttle Program came to a close, lessons learned were collected from each phase of the successful execution of these Space Shuttle missions. Specific examples of how roles and responsibilities of console positions that develop the crew and vehicle attitude timelines have been analyzed and will be discussed. Additionally, the relationships and procedural hurdles experienced through international collaboration have molded operations. These facets will be explored and related to current and future operations with the International Space Station and future vehicles. Along with these important aspects, the evolution of technology and continual improvement of data transfer tools between the Space Shuttle and ground team has also defined specific lessons used in improving the control team s effectiveness. Methodologies to communicate and transmit messages, images, and files from the Mission Control Center to the Orbiter evolved over several years. These lessons were vital in shaping the effectiveness of safe and successful mission planning and have been applied to current mission planning work in addition to being incorporated into future space flight planning. The critical lessons from all aspects of previous plan, train, and fly phases of Space Shuttle flight missions are not only documented in this paper, but are also discussed regarding how they pertain to changes in process and consideration for future space flight planning.

  2. Pricing health behavior interventions to promote adoption: lessons from the marketing and business literature.

    The relatively high cost of delivering many public health interventions limits their potential for broad public impact by reducing their likelihood of adoption and maintenance over time. Practitioners identify cost as the primary factor for which interventions they select to implement, but researchers rarely disseminate cost information or consider its importance when developing new interventions. A new approach is proposed whereby intervention developers assess what individuals and agencies adopting their interventions are willing to pay and then design interventions that are responsive to this price range. The ultimate goal is to develop effective and affordable interventions, called lean interventions, which are widely adopted and have greater public health impact. PMID:24842743

    Abstract Background: Adoption of smart devices for hospital use has been increasing with the development of health applications (apps) for patient point-of-care and hospital management. To promote the use of health apps, we describe the lessons learned from developing 12 health apps in the largest tertiary hospital in Korea. Materials and Methods: We reviewed and analyzed 12 routinely used apps in three categories—Smart Clinic, Smart Patient, and Smart Hospital—based on target users and functions. The log data for each app were collected from the date of release up until December 2012. Results: Medical personnel accessed a mobile electronic medical record app classified as Smart Clinic an average of 452 times per day. Smart Hospital apps are actively used to communicate with each other. Patients logged on to a mobile personal health record app categorized as Smart Patient an average of 222 times per day. As the mobile trend, the choice of supporting operating system (OS) is more difficult. By developing these apps, a monitoring system is needed for evaluation. Conclusions: We described the lessons learned regarding OS support, device choice, and developmental strategy. The OS can be chosen according to market share or hospital strategic plan. Smartphones were favored compared with tablets. Alliance with an information technology company can be the best way to develop apps. Health apps designed for smart devices can be used to improve healthcare. However, to develop health apps, hospitals must define their future goals and carefully consider all the aspects.

    Most TB outbreaks were caused by exposure of many people to tuberculosis bacilli due to delayed detection of initial cases who had long-lasting severe coughs and excretion of massive tuberculosis bacilli. They were also affected by several other factors, such as socio-environmental factors of the initial case; time and place of infection; and host factors of the infected persons such as immune status, infectivity, and/or pathogenicity of the bacilli. In this symposium, we learned the seriousness of infection and disease among immune-suppressed groups, special environmental factors with regard to the spread of infection, disease after treatment of latent tuberculosis infection, diagnostic specification of IGRA, and bacteriological features including genotyping of the bacilli. We reaffirmed that countermeasures for the case are important, but outbreaks can provide excellent opportunities to learn important information about infection, disease progression, etc. 1. Tuberculosis outbreak in a cancer ward: Katsuhiro KUWABARA (Division of Respiratory Diseases, National Hospital Organization Nishi-Niigata Chuo National Hospital) There was an outbreak of tuberculosis in a cancer ward of a highly specialized medical center. Outbreak cases included eight hospitalized patients and two medical staff members over a 1.5-year observation period after initial contact. Three immune-compromised patients including the index patent died of cancer and tuberculosis. Community hospitals and highly specialized medical centers, such as cancer centers, should carefully prepare a proper system to prevent nosocomial transmission of tuberculosis. 2.

    2012-01-01

    The Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument for NASA's Earth Observing System (EOS) Terra and Aqua missions. Since launch, Terra and Aqua MODIS have successfully operated for more than 12 and 10 years, respectively, and generated an unprecedented amount of data products for the science and user community over a wide range of applications. MODIS was developed with improved design and stringent calibration requirements over its heritage sensors in order . to extend and enhance their long-term data records. Its follow-on instrument, the Visible/Infrared Imager Radiometer Suite (VIIRS), was launched on-board the Suomi National Polar-orbiting Partnership (NPP) spacecraft October 28, 2011. MODIS collects data in 36 spectral bands, covering wavelengths from 0.41 to 14.S!Jlll, and at 250m, SOOm, and lkm spatial resolutions (nadir). MODIS on-orbit calibration is provided by a set of onboard calibrators (OBC), including a solar diffuser (SO), a solar diffuser stability monitor (SDSM), a blackbody (BB), and a spectroradiometric calibration assembly (SRCA). In addition to the onboard calibrators, regular lunar observations are made by both Terra and Aqua MODIS to track their calibration stability in the reflective solar region. This tutorial session provides an overview of MODIS on-orbit calibration and characterization methodologies. It discusses challenging issues and lessons learned from sensor design, operation, calibration, and inter-comparisons. Examples of instrument on-orbit performance are illustrated with a focus on the improvements made based on various lessons learned. It is expected that MODIS experience and lessons will continue to provide valuable information for future earth observing missions/sensors.

    National Aeronautics and Space Administration s (NASA) efforts in human space flight are currently focused on the Space Shuttle and International Space Station (ISS) programs, with efforts beginning on the future exploration opportunities. Both the Space Shuttle and ISS programs are important to the development of a capability for human exploration beyond Low Earth Orbit (LEO). The ISS provides extensive research capabilities to determine how the human body reacts to long duration stays in space. Also, the ISS and Shuttle can serve as a limited testbed for equipment or entire systems that may be used on missions to the Moon, Mars, or to a near-Earth asteroid. It has been nearly 35 years since the Apollo astronauts visited the Moon. Future space explorers will have to re-learn how to work and live on planetary surfaces, and how to do that for extended periods of time. Exploration crews will perform a wide assortment of scientific tasks, including material sampling and emplacement of automated instruments. Surface mission operations include the activities of the crew living and working, mission support from the Earth, and the operation of robotic and other remotely commanded equipment on the surface and in planetary orbit. Other surface activities will include the following: exploring areas surrounding a habitat; using rovers to collect rock and soil samples; setting up experiments on the surface to monitor the radiation environment and any seismic or thermal activity; and conducting scientific analyses and experiments inside a habitat laboratory. Of course, the astronauts will also have to spend some of their surface time "doing chores" and maintaining their habitat and other systems. In preparation for future planetary exploration, NASA must design the answers to many operational questions. What will the astronauts do on the surface? How will they accomplish this? What tools will they require for their tasks? How will robots and astronauts work together? What

    The sharing of 'corporate knowledge' and lessons learned in the NASA aerospace community has been identified by Johnson Space Center survey participants as a desirable tool. The concept of the program is based on creating a user friendly information system that will allow engineers, scientists, and managers at all working levels to share their information and experiences with other users irrespective of location or organization. The survey addresses potential end uses for such a system and offers some guidance on the development of subsequent processes to ensure the integrity of the information shared. This system concept will promote sharing of information between NASA centers, between NASA and its contractors, between NASA and other government agencies, and perhaps between NASA and institutions of higher learning.

    2008-01-01

    When catastrophic disasters such as Hurricane Katrina strike, psychologists and other mental health professionals often wonder how to use resources and fill needed roles. We argue that conducting clinical research in response to disasters is 1 important way that these professionals can contribute. However, we recognize that designing and implementing a clinical research study can be a daunting task, particularly in the context of the personal and system-wide chaos that follows most disasters. Thus, we offer a detailed description of our own experiences with conducting clinical research as part of our response to Hurricane Katrina. We describe our study design, recruitment and data collection efforts, and summarize and synthesize the lessons we have learned from this endeavor. Our hope is that others who may wish to conduct disaster-related research will learn from our mistakes and successes. PMID:19177173

    The Lunar CRater Observation and Sensing Satellite (LCROSS) launched with the Lunar Reconnaissance Orbiter (LRO) on June 18, 2009. While the science function of the LCROSS mission was to determine the presence of water-ice in a permanently-shadowed crater on the moon, the operational purpose was to be a pioneer for future low-cost, risk-tolerant small satellite NASA missions. Recent strategic changes at the Agency level have only furthered the importance of small satellite missions. NASA Ames Research Center and its industry partner, Northrop-Grumman, initiated this spacecraft project two-years after its co-manifest mission had started, with less than one-fifth the budget. With a $79M total cost cap (including operations and reserves) and 31-months until launch, LCROSS needed a game-changing approach to be successful. At the LCROSS Confirmation Review, the ESMD Associate Administrator asked the Project team to keep a close record of lessons learned through the course of the mission and share their findings with the Agency at the end of the mission. This paper summarizes the Project, the mission, its risk position, and some of the more notable lessons learned.

    Bruno, Erica

    2011-01-01

    When a system experiences a loading environment characterized by rapidly varying forces, such as a rocket launch, a transient analysis is used to analyze the response of the system. The most common transient analysis methodology is the Coupled Loads Analysis (CLA). CLAs are used by the automotive and aerospace industry to analyze cars, trucks, planes, helicopters, spacecraft, etc. The Space Shuttle program also uses the CLA methodology to assess the compatibility of the payload with the Orbiter and the flight environment. The Space Shuttle Verification Loads Analysis (VLA) was a standardized process that started between ten and thirteen months prior to launch, and included several meetings as well as analysis by both the Shuttle Program and the payload developers. Over the course of the Space Shuttle Program, many improvements were made to the process which helped to reduce cycle time and improve manifest flexibility. There were also several issues which were never properly addressed, but a work-around would be developed to keep the process flowing. The lessons learned included automation of some processes and standardization of others, early assessments, improved documentation and better coordination with all stakeholders in the process. Lessons learned also included the limitations in the current process, and what needs to be planned for in the future to avoid the same issues.

    The Ebola virus epidemic has topped media and political agendas for months; several countries in west Africa have faced the worst Ebola epidemic in history. At the beginning of the disease outbreak, European Union (EU) policies were notably absent regarding how to respond to the crisis. Although the epidemic is now receding from public view, this crisis has undoubtedly changed the European public perception of Ebola virus disease, which is no longer regarded as a bizarre entity confined in some unknown corner in Africa. Policy makers and researchers in Europe now have an opportunity to consider the lessons learned. In this Personal View, we discuss the EU's response to the Ebola crisis in west Africa. Unfortunately, although ample resources and opportunities for humanitarian and medical action existed, the EU did not use them to promote a rapid and well coordinated response to the Ebola crisis. Lessons learned from this crisis should be used to improve the role of the EU in similar situations in the future, ensuring that European aid can be effectively deployed to set up an improved emergency response system, and supporting the establishment of sustainable health-care services in west Africa.

    The National Optical Astronomy Observatory has joined together multiple audiences in various communities to conduct outreach using Galileoscopes. The audience consists of 5th grade students and teachers, their families and friends, and anyone else who wants to attend a special star party led by students using Galileoscopes. However, across one community there are many subcultures that one should be responsive to in the program design. The program model, which has been independently evaluated, combines professional development and classroom visits by NOAO education practitioners with the goal of a community star party. We have conducted the program in several mid-sized Arizona cities after an initial prototype star party held near the state capitol building in Phoenix. In this program, with Galileoscopes purchased with funding from Science Foundation Arizona, we have now held Galileoscope star parties in Flagstaff, Safford, and Globe, with two programs in Yuma, Arizona. We will discuss planning efforts, professional development plans and lessons learned, and specific logistical issues that have arisen in the program. Although the professional development component for teachers is rather traditional, the overall lessons learned are applicable to many astronomy programs for non-traditional audiences.

  20. Lessons learned from decommissioning projects at Los Alamos National Laboratory

    Salazar, M.

    1995-09-01

    This paper describes lessons learned over the last 20 years from 12 decommissioning projects at Los Alamos National Laboratory. These lessons relate both to overall program management and to management of specific projects during the planning and operations phases. The issues include waste management; the National Environmental Policy Act (NEPA); the Resource Conservation and Recovery Act (RCRA); the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); contracting; public involvement; client/customer interface; and funding. Key elements of our approach are to be proactive; follow the observation method; perform field activities concurrently; develop strategies to keep reportable incidents from delaying work; seek and use programs, methods, etc., in existence to shorten learning curves; network to help develop solutions; and avoid overstudying and overcharacterizing. This approach results in preliminary plans that require very little revision before implementation, reasonable costs and schedules, early acquisition of permits and NEPA documents, preliminary characterization reports, and contracting documents. Our track record is good -- the last four projects (uranium and plutonium-processing facility and three research reactors) have been on budget and on schedule.

    The Radionuclide Aerosol Sampler/Analyzer (RASA) is an automated aerosol collection and analysis system designed by Pacific Northwest National Laboratory (PNNL) in the 1990's and is deployed in several locations around the world as part of the International Monitoring System (IMS) required under the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The RASA operates unattended, save for regularly scheduled maintenance, iterating samples through a three-step process on a 24-hour interval. In its 15-year history, much has been learned from the operation and maintenance of the RASA that can benefit engineering updates or future aerosol systems. On 11 March 2011, a 9.0 magnitude earthquake and tsunami rocked the eastern coast of Japan, resulting in power loss and cooling failures at the Daiichi nuclear power plants in Fukushima Prefecture. Aerosol collections were conducted with the RASA in Richland, WA. We present a summary of the lessons learned over the history of the RASA, including lessons taken from the Fukushima incident, regarding the RASA IMS stations operated by the United States.

    Typical papers that discuss lessons learned or quality improvement focus on the challenge for a production facility reaching six sigma (3.4 Defects Per Million Opportunities) from five sigma. This paper discusses lessons learned when the Los Alamos National Laboratory's (LANL) transuranic (TRU) waste management project was challenged to establish a production system to meet the customer's expectations. The target for FY 2003 was set as two shipments of TRU waste per week leaving the site. The average for the four previous years (FY99-02) was about one shipment every two months. LANL recognized that, despite its success in 1999 as the first site to ship TRU waste to open the Waste Isolation Pilot Plant (WIPP), significant changes to the way business was being done were required to move to a production mode. Process improvements began in earnest in April 2002. This paper discusses several of the initiatives LANL took to achieve forty-five shipments in FY03. The paper is organized by topic into five major areas that LANL worked to get the job done.

    2004-08-01

    The historic trend of the space industry towards lower cost programmes and more generally a better economic efficiency raises a difficult question to the quality assurance community: how to achieve the same—or better—mission success rate while drastically reducing the cost of programmes, hence the cost and level of quality assurance activities. EADS Astrium Earth Observation and Science (France) Business Unit have experimented Risk Management and Lessons Learned on their satellite programmes to achieve this goal. Risk analysis and management are deployed from the programme proposal phase through the development and operations phases. Results of the analysis and the corresponding risk mitigation actions are used to tailor the product assurance programme and activities. Lessons learned have been deployed as a systematic process to collect positive and negative experience from past and on-going programmes and feed them into new programmes. Monitoring and justification of their implementation in programmes is done under supervision from the BU quality assurance function. Control of the system is ensured by the company internal review system. Deployment of these methods has shown that the quality assurance function becomes more integrated in the programme team and development process and that its tasks gain focus and efficiency while minimising the risks associated with new space programmes.

    2004-01-01

    This report is the final product of a 90-day study performed for the Exploration Systems Mission Directorate. The study was to assemble lessons NASA has learned from previous programs that could help the Exploration Systems Mission Directorate pursue the Exploration vision. It focuses on those lessons that should have the greatest significance to the Directorate during the formulation of program and mission plans. The study team reviewed a large number of lessons learned reports and data bases, including the Columbia Accident Investigation Board and Rogers Commission reports on the Shuttle accidents, accident reports from robotic space flight systems, and a number of management reviews by the Defense Sciences Board, Government Accountability Office, and others. The consistency of the lessons, findings, and recommendations validate the adequacy of the data set. In addition to reviewing existing databases, a series of workshops was held at each of the NASA centers and headquarters that included senior managers from the current workforce as well as retirees. The full text of the workshop reports is included in Appendix A. A lessons learned website was opened up to permit current and retired NASA personnel and on-site contractors to input additional lessons as they arise. These new lessons, when of appropriate quality and relevance, will be brought to the attention of managers. The report consists of four parts: Part 1 provides a small set of lessons, called the Executive Lessons Learned, that represent critical lessons that the Exploration Systems Mission Directorate should act on immediately. This set of Executive Lessons and their supporting rationale have been reviewed at length and fully endorsed by a team of distinguished NASA alumni; Part 2 contains a larger set of lessons, called the Selected Lessons Learned, which have been chosen from the lessons database and center workshop reports on the basis of their specific significance and relevance to the near

  6. The Space Place: Adventures in Informal Education - and Lessons Learned

    NASA Astrophysics Data System (ADS)

    Fisher, D.; Leon, N.

    2001-12-01

    Informal education settings provide unique opportunities to convey Earth and space science learning to a variety of audiences. The NASA Space Place suite of outreach products and activities include deliverables to both the formal and the informal education arenas. The question is, how can Earth and space science efforts best create high-quality products and activities for the informal education sector- and how can these products and activities be effectively disseminated to these audiences? This session will describe the approach by a small outreach team for NASA's New Millennium Program (NMP) Space Place effort. The Space Place team's approach has been three-fold: 1) develop a suite of products designed to appeal to (and educate) the informal education audience, 2) disseminate these products through leveraged distribution channels which serve the informal education community, and 3) invite participation by missions beyond those within NMP, but rather NASA-wide - for a richer and broader message, and a greater variety of content The informal education audience served by the Space Place can be found in science centers, museums, planetariums, libraries, community centers, and community organizations. This informal education audience seeks to be entertained as well as to be educated, and this audience often includes multiple generations. Personnel at informal education venues may or may not have a science background, may or may not have significant training in conducting activities, and may, as often as not, be volunteers. As a result of valuable lessons learned, Space Place materials developed for informal education settings attempt to be adaptable for multiple age groups, and easy to administer. Dissemination to the informal education community could be a daunting effort. But another lesson learned by the Space Place team is the value of alliances with national organizations within that community. These alliances make distribution of the Space Place activities and

    Beggan, Dominic M

    2010-01-01

    This paper examines the impact of Hurricane Rita on one of the many universities along the Gulf Coast of the United States: Lamar University in Beaumont, Texas. Hurricane Rita, which made landfall between Sabine Pass, Texas, and Johnson's Bayou, Louisiana, on 24 September 2005, is the fourth strongest Atlantic Ocean hurricane on record and the most intense tropical cyclone ever observed in the Gulf of Mexico. This paper assesses the tasks that confronted the administration, faculty, and students of Lamar University in the days and weeks after the event. It concludes that the one factor that will influence more than any other the degree of success after any disaster is whether all levels of the administrative command institutionalise, endorse, promote, and encourage the adopted recovery plan. The research seeks to share valuable insights on the vulnerabilities that academic institutions face during natural disasters and to highlight some of the many lessons learned. PMID:19624700

    In this methodological article, we examine participatory methods in depth to demonstrate how these methods can be adopted for quality improvement (QI) projects in health care. We draw on existing literature and our QI initiatives in the Department of Veterans Affairs to discuss the application of photovoice and guided tours in QI efforts. We highlight lessons learned and several benefits of using participatory methods in this area. Using participatory methods, evaluators can engage patients, providers, and other stakeholders as partners to enhance care. Participant involvement helps yield actionable data that can be translated into improved care practices. Use of these methods also helps generate key insights to inform improvements that truly resonate with stakeholders. Using participatory methods is a valuable strategy to harness participant engagement and drive improvements that address individual needs. In applying these innovative methodologies, evaluators can transcend traditional approaches to uniquely support evaluations and improvements in health care. PMID:26667882

    This presentation has shown the accomplishments of the PASS project over three decades and highlighted the lessons learned. Over the entire time, our goal has been to continuously improve our process, implement automation for both quality and increased productivity, and identify and remove all defects due to prior execution of a flawed process in addition to improving our processes following identification of significant process escapes. Morale and workforce instability have been issues, most significantly during 1993 to 1998 (period of consolidation in aerospace industry). The PASS project has also consulted with others, including the Software Engineering Institute, so as to be an early evaluator, adopter, and adapter of state-of-the-art software engineering innovations.

    Although Contingency Management has been shown to be effective in substance use treatments, community adoption has been slow. In order to increase dissemination of contingency management (CM) into community practice, two community treatment programs collaborated with university faculty investigators to design, implement, and evaluate low-cost, prize-based CM interventions delivered by treatment staff using Petry’s (2000) fishbowl technique. A pre-post study design was used to evaluate the impact of CM on outpatient group attendance. All clients attending the targeted outpatient groups at both treatment programs were eligible to participate. Group attendance was significantly positively impacted after intervention implementation. This is one of the first studies demonstrating successful implementation of CM by community treatment program counselors within their existing treatment groups. The discussion focuses on practical lessons learned during the planning and implementation of the interventions. PMID:20598838

    In this methodological article, we examine participatory methods in-depth to demonstrate how these methods can be adopted for quality improvement (QI) projects in health care. We draw on existing literature and our QI initiatives in the Department of Veterans Affairs to discuss the application of photovoice and guided tours in QI efforts. We highlight lessons learned and several benefits of using participatory methods in this area. Using participatory methods, evaluators can engage patients, providers and other stakeholders as partners to enhance care. Participant involvement helps yield actionable data that can be translated into improved care practices. Use of these methods also helps generate key insights to inform improvements that truly resonate with stakeholders. Using participatory methods is a valuable strategy to harness participant engagement and drive improvements that address individual needs. In applying these innovative methodologies, evaluators can transcend traditional approaches to uniquely support evaluations and improvements in health care. PMID:26667882

  13. Selected Lessons Learned in Space Shuttle Orbiter Propulsion and Power Subsystems

    2011-01-01

    Over its 30 years of space flight history, plus the nearly 10 years of design, development test and evaluation, the Space Shuttle Orbiter is full of lessons learned in all of its numerous and complex subsystems. In the current paper, only selected lessons learned in the areas of the Orbiter propulsion and power subsystems will be described. The particular Orbiter subsystems include: Auxiliary Power Unit (APU), Hydraulics and Water Spray Boiler (WSB), Mechanical Flight Controls, Main Propulsion System (MPS), Fuel Cells and Power Reactant and Storage Devices (PRSD), Orbital Maneuvering System (OMS), Reaction Control System (RCS), Electrical Power Distribution (EPDC), electrical wiring and pyrotechnics. Given the complexity and extensive history of each of these subsystems, and the limited scope of this paper, it is impossible to include most of the lessons learned; instead the attempt will be to present a selected few or key lessons, in the judgment of the authors. Each subsystem is presented separate, beginning with an overview of the hardware and their function, a short description of a few historical problems and their lessons, followed by a more comprehensive table listing of the major subsystem problems and lessons. These tables serve as a quick reference for lessons learned in each subsystem. In addition, this paper will establish common lessons across subsystems as well as concentrate on those lessons which are deemed to have the highest applicability to future space flight programs.

    IPY Education, Outreach and Communications planning and implementation occurred with a minimum of staff and resources and a maximum of international volunteer enthusiasm and energy. Although many relatively well-funded and remarkable national activities occurred, sharing and promoting these internationally depended entirely on the volunteer networks of individuals and institutions. Through these partnerships we have learned valuable lessons about impact and distribution, and challenged several assumptions about educational partnerships. For example, we learned the importance of regular pre-scheduled events, and how to use networks of volunteer translators and free geobrowser tools. We have learned how best to conduct planning meetings and live events across time zones and hemispheres, and shown how the best concepts and ideas of science education can propagate across age groups and among languages. We have learned the optimal times of year for international events, and the most effective means for international distribution and communication. We have established a rapid-response help desk without home or staff, and sustained active and high-impact interactions with journalists largely without press releases. We have shown that, in general, wide-spread distribution of freely accessible materials produces a better impact than embargoes and restrictions. Most fundamentally, we have exposed a pervasive interest in polar science and a hunger for climate information, and responded with an active, flexible, and efficient network of partners and products.

  19. Lessons Learned from Radioactive Waste Storage and Disposal Facilities

    SciTech Connect

    Esh, David W.; Bradford, Anna H.

    2008-01-15

    The safety of radioactive waste disposal facilities and the decommissioning of complex sites may be predicated on the performance of engineered and natural barriers. For assessing the safety of a waste disposal facility or a decommissioned site, a performance assessment or similar analysis is often completed. The analysis is typically based on a site conceptual model that is developed from site characterization information, observations, and, in many cases, expert judgment. Because waste disposal facilities are sited, constructed, monitored, and maintained, a fair amount of data has been generated at a variety of sites in a variety of natural systems. This paper provides select examples of lessons learned from the observations developed from the monitoring of various radioactive waste facilities (storage and disposal), and discusses the implications for modeling of future waste disposal facilities that are yet to be constructed or for the development of dose assessments for the release of decommissioning sites. Monitoring has been and continues to be performed at a variety of different facilities for the disposal of radioactive waste. These include facilities for the disposal of commercial low-level waste (LLW), reprocessing wastes, and uranium mill tailings. Many of the lessons learned and problems encountered provide a unique opportunity to improve future designs of waste disposal facilities, to improve dose modeling for decommissioning sites, and to be proactive in identifying future problems. Typically, an initial conceptual model was developed and the siting and design of the disposal facility was based on the conceptual model. After facility construction and operation, monitoring data was collected and evaluated. In many cases the monitoring data did not comport with the original site conceptual model, leading to additional investigation and changes to the site conceptual model and modifications to the design of the facility. The following cases are discussed

  4. Lessons from 2012: What the NHS Can Learn from Britain's Olympic Success.

    PubMed

    Maile, Edward J; Blake, Alastair M

    2013-01-01

    The 2012 London Olympic and Paralympic Games were widely regarded as an organisational and sporting success for the United Kingdom. Therefore, it is prudent to consider what other large, public endeavours might learn from the Games' success. Team GB worked to develop a positive team culture based around shared values. This is something the National Health Service (NHS) could learn from, as an organisation which can appear to lack this culture. The NHS should also work harder to adopt evidence-based practices, and to adopt them quickly, as is often the case in sport. Sport is the ultimate example of transparent results reporting, and the NHS ought to consider systematic reporting of risk-adjusted performance data, which may drive improved performance. The NHS should pay attention to the experiences of successful Olympic sports with centralised centres of excellence, and to medical data which suggests that better outcomes result from centres of excellence. The NHS and wider government should look to Olympic athletes and place more emphasis on prevention of disease by encouraging positive lifestyle choices. Finally, the NHS should develop private sector partnerships carefully. We must look to gather knowledge and ideas from every area of life in pursuit of excellence in the NHS. Experience of the Olympics offers a number of instructive lessons. PMID:25737779

    The main objectives of space product assurance are, in effect, the same as those of Total Quality Management (TQM) or its many variants. The most significant ingredients are the lessons learned and their application to ongoing and future programs as they are affected by changes in the cultural environment. The cultural issues which affect almost everything done in technical programs and projects are considered. Understanding the lessons learned and the synergism which results from this combination of knowledge, culture, and lessons learned is identified as crucial. A brief discussion of the closed loop linkage that should exist between the world of hands on activities and that of educational institutions is presented.

  6. Lessons Learned from HIV Vaccine Clinical Efficacy Trials

    Day, Tracey A.; Kublin, James G.

    2014-01-01

    The past few years have witnessed many promising advances in HIV prevention strategies involving pre-exposure prophylaxis approaches. Some may now wonder whether an HIV vaccine is still needed, and whether developing one is even possible. The partial efficacy reported in the RV144 trial and the encouraging results of the accompanying immune correlates analysis suggest that an effective HIV vaccine is achievable. These successes have provided a large impetus and guidance for conducting more HIV vaccine trials. A key lesson learned from RV144 is that assessment of HIV acquisition is now a feasible and valuable primary objective for HIV preventive vaccine trials. In this article we review how RV144 and other HIV vaccine efficacy trials have instructed the field and highlight some of the HIV vaccine concepts in clinical development. After a long and significant investment, HIV vaccine clinical research is paying off in the form of valuable lessons that, if applied effectively, will accelerate the path toward a safe and effective vaccine. Together with other HIV prevention approaches, preventive and therapeutic HIV vaccines will be invaluable tools in bringing the epidemic to an end. PMID:24033299

    The Native Peoples-Native Homelands Climate Change Workshop was held on October 28 through November 01, 1998, as part of a series of workshops being held around the U.S. to improve the understanding of the potential consequences of climate variability and change for the Nation. This workshop was specifically designed by Native Peoples to examine the impacts of climate change and extreme weather variability on Native Peoples and Native Homelands from an indigenous cultural and spiritual perspective and to develop recommendations as well as identify potential response actions. The workshop brought together interested Native Peoples, representatives of Tribal governments, traditional elders, Tribal leaders, natural resource managers, Tribal College faculty and students, and climate scientists from government agencies and universities. It is clear that Tribal colleges and universities play a unique and critical role in the success of these emerging partnerships for decision-making in addition to the important education function for both Native and non-Native communities such as serving as a culturally- appropriate vehicle for access, analysis, control, and protection of indigenous cultural and intellectual property. During the discussions between scientists and policy-makers from both Native and non-Native communities, a number of important lessons emerged which are key to building more effective partnerships between Native and non-Native communities for collaboration and decision-making for a more sustainable future. This talk summarizes the key issues, recommendations, and lessons learned during this workshop.

    1999-09-01

    The Puerto Rico Electric Power Authority (PREPA) installed a distributed battery energy storage system in 1994 at a substation near San Juan, Puerto Rico. It was patterned after two other large energy storage systems operated by electric utilities in California and Germany. The U.S. Department of Energy (DOE) Energy Storage Systems Program at Sandia National Laboratories has followed the progress of all stages of the project since its inception. It directly supported the critical battery room cooling system design by conducting laboratory thermal testing of a scale model of the battery under simulated operating conditions. The Puerto Rico facility is at present the largest operating battery storage system in the world and is successfully providing frequency control, voltage regulation, and spinning reserve to the Caribbean island. The system further proved its usefulness to the PREPA network in the fall of 1998 in the aftermath of Hurricane Georges. The owner-operator, PREPA, and the architect/engineer, vendors, and contractors learned many valuable lessons during all phases of project development and operation. In documenting these lessons, this report will help PREPA and other utilities in planning to build large energy storage systems.

  9. Learning from extraordinary lovers: lessons from the edge.

    Kleinplatz, Peggy J

    2006-01-01

    This paper discusses lessons about sexuality and eroticism gleaned from those who engage in extraordinary sex, even though such relationships have typically been classified as pathological. What can clinicians learn from those who seek and attain uncommon sexual relations? Such individuals' sexual epistemology, goals, understanding of the nature and spectrum of sexual and erotic relations, communication strategies and "outcome" criteria can provide valuable lessons for those who treat sexual problems or aim to overcome sexual mediocrity. For example, while traditional sex therapy often focuses on what is on the surface, some SM participants are interested in the meanings that lie at a deeper level. Whereas conventional clinicians may focus on enabling particular sexual acts (especially heterosexual intercourse), SM participants are more apt to be concerned with the varied spectrum of underlying purposes motivating these acts. Whereas many couples are willing to settle for merely functional sex, SM practitioners may be more interested in contact that necessitates intense, erotic connection; sophisticated communication of subtle differences in intent; and eventuates in profound self-knowledge and transcendent levels of intimacy. Illustrative case examples are provided. PMID:16803770

  11. Caring for the Family Caregiver: Lessons Learned in Child Health.

    PubMed

    Keilty, Krista; Cohen, Eyal

    2015-01-01

    Policy to support informal caregivers is a critical health policy issue in Canada. Lessons may be learned from the perspectives and experience in the child health field with applicability for all cared-for persons and their informal caregivers. Familycentred care addresses the centrality of the family caregiver in the design and delivery of health services. A life course approach focuses on key periods of transition and downstream effects facing caregivers over their lifetime. The medical home model where care delivery is more coordinated offers potential direct cost savings for both family caregivers and the healthcare system. Models of pediatric home care that focus on promoting caregiver capacity and integration of unregulated providers show the promise of being acceptable and sustainable solutions to increasing demands for caregiver respite. Finally, a number of assumptions that are somewhat unique to the pediatric caregiver experience are explored and/or challenged. These lessons and assumptions may provide insight for policymakers in the development of systems and supports for all cared-for persons and their caregivers in Canada. PMID:26626116

  12. Massachusetts nuclear power referendum: Lessons learned from the campaign trail

    SciTech Connect

    Allen, S.R.

    1989-01-01

    Last November, Massachusetts voters cast their ballots on a binding initiative which, if passed, would have prohibited the production of high-level waste, thereby permanently shutting down the state's two nuclear power plants: Yankee and Pilgrim. Question 4, as the initiative became known, posed an unprecedented challenge for the state's six major utilities. Essentially, Question 4 was defeated for two reasons: compelling arguments and a well-founded strategy for communicating those arguments. One part of that strategy was the use of debates and public-speaking engagements before both civic groups and on radio/television. These debates and presentations were clearly the most interesting part of the campaign and provided many insights that may be applied to long-term public policy and informational programs. Obviously, there is a significant difference between an intense, focused campaign and an ongoing, diverse public information program-but many of the principles are the same. The purpose of this paper is to review some of the key lessons learned from over 300 debates and presentations in the highly emotional atmosphere of the Question 4 campaign. Throughout the campaign, debaters and speakers submitted after action reports, and it is from these as well as the overall campaign results that the lessons and anecdotes are derived.

    2013-01-01

    These are science and mission design and operations lessons learned from the Stardust Mission, which returned grains from comet Wild-2 and fresh interstellar dust to Earth in 2006 [1]. Science Lessons: Major discoveries of the Stardust Wild-2 samples include the presence of numerous chondrules and CAI in a comet, which requires a much more dynamic early solar system than many had envisaged, and verified predictions made by models requiring outward flow of early solar system solids before the early nebular gas had dissipated [1-3]. No evidence has been found for the presence of live Al-26 in the comet, suggesting late accretion [4]. Carbonates and unusual sulfides were found which potentially require activity of liquid water within the comet, but to only a minor degree at best [5-6]. The presence of abundant thermally-metamorphosed silicates in Wild-2 appears to require assembly from an earlier generation of bodies [7]. The abundance of presolar grains in the Wild-2 samples appears to be below what has been found in most chondritic IDPs and primitive chondrites [1]. The bulk mineralogy of Wild-2 grains does not match the mineralogy from any single other known astromaterial [7], and is also strikingly unlike that inferred from Spitzer Telescope spectra of Comet Temple 1 dust [8]. Amino acids and other fragile organics have been detected among the Wild-2 samples [9], which highlights the critical importance of further developing techniques for organic analysis in small samples, and cleaning outbound spacecraft.

  15. Lesson Study-Building Communities of Learning Among Pre-Service Science Teachers

    NASA Astrophysics Data System (ADS)

    Hamzeh, Fouada

    Lesson Study is a widely used pedagogical approach that has been used for decades in its country of origin, Japan. It is a teacher-led form of professional development that involves the collaborative efforts of teachers in co-planning and observing the teaching of a lesson within a unit for evidence that the teaching practices used help the learning process (Lewis, 2002a). The purpose of this research was to investigate if Lesson Study enables pre-service teachers to improve their own teaching in the area of science inquiry-based approaches. Also explored are the self-efficacy beliefs of one group of science pre-service teachers related to their experiences in Lesson Study. The research investigated four questions: 1) Does Lesson Study influence teacher preparation for inquiry-based instruction? 2) Does Lesson Study improve teacher efficacy? 3) Does Lesson Study impact teachers' aspiration to collaborate with colleagues? 4) What are the attitudes and perceptions of pre-service teachers to the Lesson Study idea in Science? The 12 participants completed two pre- and post-study surveys: STEBI- B, Science Teaching Efficacy Belief Instrument (Enochs & Riggs, 1990) and ASTQ, Attitude towards Science Teaching. Data sources included student teaching lesson observations, lesson debriefing notes and focus group interviews. Results from the STEBI-B show that all participants measured an increase in efficacy throughout the study. This study added to the body of research on teaching learning communities, professional development programs and teacher empowerment.

    The purpose of this presentation is to relay the experience of the Office of New Production Reactors (NP) in developing and implementing its pollution prevention program. NP was established to plan, design, and construct a new safe and environmentally acceptable nuclear reactor capacity necessary to provide an assured supply of tritium to maintain the nation`s long-term deterrent capability. The Program offered the Department of Energy an opportunity to demonstrate its commitment to environmental protection via minimization of environmental releases; new design offers the best opportunity for pollution prevention. The NP pollution prevention program was never fully implemented because NP`s tritium production design activity was recovery terminated. The information in this paper represented lessons learned from the last three years of NP operation.

    Medical imaging is one of the most important diagnostic instruments in clinical practice. The technological development of digital medical imaging has enabled healthcare services to undertake large scale projects that require the participation and collaboration of many professionals of varied backgrounds and interests as well as substantial investments in infrastructures. Rather than focusing on systems for dealing with digital medical images, this article deals with the management of projects for implementing these systems, reviewing various organizational, technological, and human factors that are critical to ensure the success of these projects and to guarantee the compatibility and integration of digital medical imaging systems with other health information systems. To this end, the author relates several lessons learned from a review of the literature and the author's own experience in the technical coordination of digital medical imaging projects.

    The PEP-II B-Factory collider ended the final phase of operation at nearly twice the design current and 4X the design luminosity. To highlight the evolution from the original conceptual design through to the 1.2E34 final machine we choose one example each from the broadband feedback and from the LLRF system. They illustrate the original design estimation missed some very significant details, and how in the course of PEP-II operation unexpected difficulties led to significant insights and new approaches which allowed higher machine performance. We present valuable 'lessons learned' which are of interest to designers of next generation feedback and impedance controlled LLRF systems.

    Abstract: Identifying and understanding digital instrumentation and control (I&C) cyber vulnerabilities within nuclear power plants and other nuclear facilities, is critical if nation states desire to operate nuclear facilities safely, reliably, and securely. In order to demonstrate objective evidence that cyber vulnerabilities have been adequately identified and mitigated, a testbed representing a facility’s critical nuclear equipment must be replicated. Idaho National Laboratory (INL) has built and operated similar testbeds for common critical infrastructure I&C for over ten years. This experience developing, operating, and maintaining an I&C testbed in support of research identifying cyber vulnerabilities has led the Korean Atomic Energy Research Institute of the Republic of Korea to solicit the experiences of INL to help mitigate problems early in the design, development, operation, and maintenance of a similar testbed. The following information will discuss I&C testbed lessons learned and the impact of these experiences to KAERI.

Some lessons learned by transitioning anesthesia reporting and monitoring devices (ARMDs) on a local area network (LAN) to integration of anesthesia documentation within a CIS include the following categories: access, contracting, deployment, implementation, planning, security, support, training and workflow integration. Areas identified for improvement include: Vendor requirements for access reconciled with the organizations' security policies and procedures. Include clauses supporting transition from stand-alone devices to information integrated into clinical workflow in the medical device procurement contract. Resolve deployment and implementation barriers that make the process less efficient and more costly. Include effective field communication and creative alternatives in planning. Build training on the baseline knowledge of trainees. Include effective help desk processes and metrics. Have a process for determining where problems originate when systems share information.

    1990-01-01

    Hardware representative of essentially every major equipment item necessary for reprocessing breeder reactor nuclear fuel has been installed and tested for remote maintainability. This testing took place in a cold mock-up of a remotely maintained hot cell operated by the Consolidated Fuel Reprocessing Program (CFRP) within the Fuel Recycle Division at Oak Ridge National Laboratory (ORNL). The reprocessing equipment tested included a Disassembly System, a Shear System, a Dissolver System, an Automated Sampler System, removable Equipment Racks on which various chemical process equipment items were mounted, and an advanced servomanipulator (ASM). These equipment items were disassembled and reassembled remotely by using the remote handling systems that are available within the cold mock-up area. This paper summarizes the lessons learned'' as a result of the numerous maintenance activities associated with each of these equipment items. 4 refs., 3 figs., 1 tab.

    2010-01-01

    Several unintentional hypergolic fluid related spills, fires, and explosions from the Apollo Program, the Space Shuttle Program, the Titan Program, and a few others have occurred over the past several decades. Spill sites include the following government facilities: Kennedy Space Center (KSC), Johnson Space Center (JSC), White Sands Test Facility (WSTF), Vandenberg Air Force Base (VAFB), Cape Canaveral Air Force Station (CCAFS), Edwards Air Force Base (EAFB), Little Rock AFB, and McConnell AFB. Until now, the only method of capturing the lessons learned from these incidents has been "word of mouth" or by studying each individual incident report. Through studying several dozen of these incidents, certain root cause themes are apparent. Scrutinizing these themes could prove to be highly beneficial to future hypergolic system testing, checkout, and operational use.

    Population expansion and rapid economic development have been and will continue placing dramatic pressure on Chinese land resources to provide food, water, and energy. Globalisation and international cooperation makes China land use system inseparable from the rest of the world. In this study, we will first analyze the historic changes of food supply/demand in China during the past by ensemble all the available dataset and information from literature. During the past 60 years, China has been self-fed its own population benefiting from the increase of productivity which helps provide enough food. By analyzing the factors behind of the increase of productivity, it raises quite some concerns with future development. Projections of possible pathways of development will be discussed in this paper. Lessons learn from the past will help study food security in other countries particularly in countries like India or African countries.

    2015-01-01

    There is growing interest in applying novel eHealth approaches for the prevention and management of various health conditions, with the ultimate goal of increasing positive patient outcomes and improving the effectiveness and efficiency of health services delivery. Coupled with the use of innovative approaches is the possibility for adverse outcomes, highlighting the need to strategically refine digital practices prior to implementation with patients. One appropriate method for modification purposes includes focus groups. Although it is a well-established method in qualitative research, there is a lack of guidance regarding the use of focus groups for digital intervention refinement. To address this gap, the purpose of our paper is to highlight several lessons our research team has learned in using focus groups to help refine digital interventions prior to use with patients.

    In recent years, community-based coalitions have become an effective channel to addressing various health problems within specific ethnic communities. The purpose of this article is twofold: (a) to describe the process involved in building the Kalusugan Coalition (KC), a Filipino American health coalition based in New York City, and (b) to highlight the lessons learned and the challenges from this collaborative venture. The challenges described also offer insights on how the coalition development process can be greatly affected by the partnership with an academic institution on a community-based research project. Because each cultural group has unique issues and concerns, the theoretical framework used by KC offers creative alternatives to address some of the challenges regarding coalition infrastructures, leadership development, unexpected change of coalition dynamics, and cultural nuances.

    2015-01-01

    Finding solutions to thermal coating issues on the Deep Space Climate Observatory (DSCOVR) mission was a very challenging and unique endeavor. As a passive thermal control system, coatings provide the desired thermal, optical, and electrical charging properties, while surviving a harsh space environment. DSCOVR mission hardware was repurposed from the late 1990s satellite known as Triana. As a satellite that was shelved for over a decade, the coating surfaces consequently degraded with age, and became fairly outdated. Although the mission successfully launched in February 2015, there were unfamiliar observations and unanticipated issues with the coating surfaces during the revival phases of the project. For example, the thermal coatings on DSCOVR experienced particulate contamination and resistivity requirement problems, among other issues. While finding solutions to these issues, valuable lessons were learned in thermal coatings that may provide great insight to future spaceflight missions in similar situations.

    Materials behaviors caused by neutron irradiation under fission and/or fusion environments can be little understood without practical examination. Easily accessible material information system with large material database using effective computers is necessary for design of nuclear materials and analyses or simulations of the phenomena. The developed Embrittlement Data Base (EDB) at ORNL is this comprehensive collection of data. EDB database contains power reactor pressure vessel surveillance data, the material test reactor data, foreign reactor data (through bilateral agreements authorized by NRC), and the fracture toughness data. The lessons learned from building EDB program and the associated database management activity regarding Material Database Design Methodology, Architecture and the Embedded QA Protocol are described in this report. The development of IAEA International Database on Reactor Pressure Vessel Materials (IDRPVM) and the comparison of EDB database and IAEA IDRPVM database are provided in the report. The recommended database QA protocol and database infrastructure are also stated in the report.

    Although this is in many ways a good era for women, many things have yet to improve. Women continue to lag behind men with regard to salaries, are under-represented in position of leadership, and still take on greater responsibility for child rearing and family responsibilities. Careers dominated by women tend to be associated with lower salaries and lower prominence and by the same token, women tend to dominate leadership positions when the field becomes less prestigious. Although women now outnumber men in graduating classes, the feminization of clinical psychology brings new challenges. This special series comes out of the 2009 trailblazer panel held at the ABCT convention in New York City, which explored the experiences faced by pioneering women in behavior therapy and discussed ways to help women overcome the glass ceiling. This introductory paper summarizes the lessons learned by these trailblazers with a view toward helping women in academia today. PMID:23046770

    2000-01-01

    The Advanced Communications Satellite (ACTS) was conceived and developed in the mid- 1980s as an experimental satellite to demonstrate unproven Ka-band technology, and potential new commercial applications and services. Since launch into geostationary orbit in September 1993. ACTS has accumulated almost seven years of essentially trouble-free operation and met all program objectives. The unique technology, service experiments. and system level demonstrations accomplished by ACTS have been reported in many forums over the past several years. As ACTS completes its final experiments activity, this paper will relate the top-level program goals that have been achieved in the design, operation, and performance of the particular satellite subsystems. Pre-launch decisions to ensure satellite reliability and the subsequent operational experiences contribute to lessons learned that may be applicable to other comsat programs.

    After two birth peaks and the “one child per family” policy, China is facing unprecedented challenges with regard to its aging population. This article analyzes the problems associated with three traditional ways of caring for older Chinese, the current health care system, and social supports available to older Chinese. The “4-2-1” family structure and the “empty nest” undermine family support, the prevalence of chronic illnesses and lack of money reduce older adults’selfcare abilities, and insufficient care facilities threaten social support. Lessons learned from the United States show that community-based nursing models, nursing curriculum reforms with a gerontology focus, and reformed health care systems are pivotal for addressing China’s crisis.

    A cyclic integrated reversible-bending fatigue tester (CIRFT) was developed to support U.S. NRC and DOE Used Fuel Disposition Campaign studies on high burn-up (HBU) spent nuclear fuel (SNF) transportation during normal conditions of transport (NCT). Two devices were developed; the first CIRFT was successfully installed and operated in the ORNL hot-cells in September 2013. Since hot cell testing commenced several HBU SNF samples from both Zr-4 and M5 clads were investigated. The second CIRFT device was developed in February 2014, and has been used to test clad/fuel surrogate rods (stainless steel with alumina pellet inserts). The second CIRFT machine has also been used for sensor development and test sensitivity analyses, as well as loading boundary condition parameter studies. The lessons learned from CIRFT testing will be presented in this paper.

    The Plutonium-Uranium Extraction (PUREX) Facility operated from 1956-1972, from 1983-1988, and briefly during 1989-1990 to produce for national defense at the Hanford Site in Washington State. The Uranium Trioxide (UO{sub 3}) Facility operated at the Hanford Site from 1952-1972, 1984-1988, and briefly in 1993. Both plants were ordered to permanent shutdown by the U.S. Department of Energy (DOE) in December 1992, thus initiating their deactivation phase. Deactivation is that portion of a facility`s life cycle that occurs between operations and final decontamination and decommissioning (D&D). This document details the history of events, and the lessons learned, from the time of the PUREX Stabilization Campaign in 1989-1990, through the end of the first full fiscal year (FY) of the deactivation project (September 30, 1994).

    Data warehouse projects are perceived to be risky and prone to failure due to many organizational and technical challenges. However, often iterative and lengthy processes of implementation of data warehouses at an enterprise level provide an opportunity for formative evaluation of these solutions. This paper describes lessons learned from successful development and implementation of the first phase of an enterprise data warehouse to support public health surveillance at British Columbia Centre for Disease Control. Iterative and prototyping approach to development, overcoming technical challenges of extraction and integration of data from large scale clinical and ancillary systems, a novel approach to record linkage, flexible and reusable modeling of clinical data, and securing senior management support at the right time were the main factors that contributed to the success of the data warehousing project.

    2008-01-01

    Lessons learned from the International Space Station have indicated that early attention to acoustics will be key to achieving safer, more productive environments for new long duration missions. Fans are known to be dominant noise sources, and reducing fan noise poses challenges for fan manufacturers and systems engineers. The NASA Glenn Acoustics Branch has considered ways in which expertise and capabilities traditionally used to understand and mitigate aircraft engine noise can be used to address small fan noise issues in Exploration and Information Technology applications. Many could benefit if NASA can capture what is known about small fan aero and acoustic performance in a "Guide for the Design, Selection, and Installation of Fans for Spaceflight Applications." A draft outline for this document will be offered as a useful starting point for brainstorming ideas for the various smaller, near-term research projects that would need to be addressed first.

    1986-01-01

    Recently, the military and civil technical communities have undertaken numerous studies of the high angle-of-attack aerodynamic characteristics of advanced airplane and missile configurations. The method of approach and the design methodology employed have necessarily been experimental and exploratory in nature, due to the complex nature of separated flows. However, despite the relatively poor definition of many of the key aerodynamic phenomena involved for high-alpha conditions, some generic guidelines for design consideration have been identified. The present paper summarizes some of the more important lessons learned in the area of high angle-of-attack aerodynamics with examples of a number of key concepts and with particular emphasis on high-alpha stability and control characteristics of high performance aircraft. Topics covered in the discussion include the impact of design evolution, forebody flows, control of separated flows, configuration effects, aerodynamic controls, wind-tunnel flight correlation, and recent NASA research activities.

    As part of an international public health partnership formed in 2001 we assessed the impact of Project Northland in Croatia--an adolescent alcohol school-based prevention intervention implemented in Split--on students. The curriculum was implemented in 13 randomly selected schools with another 13 schools serving as controls. The evaluation included quantitative and qualitative methods, using pre/post-tests to compare intervention and controls and follow-up focus groups with parents and teachers. Quantitative data showed the intervention was more successful in changing attitudes in the first two years, but had less impact on older students. Qualitative data suggest benefits from the program overall. Given the intervention was successful in the earlier grades it should be initiated earlier to have a greater impact. Challenges and lessons learned are offered. PMID:18592807

    2016-01-01

    The lessons learned regarding the resuscitation of traumatic hemorrhagic shock are numerous and come from a better understanding of the epidemiology, pathophysiology, and experience in this population over 10-plus years of combat operations. We have now come to better understand that the greatest benefit in survival can come from improved treatment of hemorrhage in the prehospital phase of care. We have learned that there is an endogenous coagulopathy that occurs with severe traumatic injury secondary to oxygen debt and that classic resuscitation strategies for severe bleeding based on crystalloid or colloid solutions exacerbate coagulopathy and shock for those with life-threatening hemorrhage. We have relearned that a whole blood-based resuscitation strategy, or one that at least recapitulates the functionality of whole blood, may reduce death from hemorrhage and reduce the risks of excessive crystalloid administration which include acute lung injury, abdominal compartment syndrome, cerebral edema, and anasarca. Appreciation of the importance of shock and coagulopathy management underlies the emphasis on early hemostatic resuscitation. Most importantly, we have learned that there is still much more to understand regarding the epidemiology, pathophysiology, and the resuscitation strategies required to improve outcomes for casualties with hemorrhagic shock.

    Among the principal objectives of the Phase 1 NASA/Mir program were for the United States to gain experience working with an international partner, to gain working experience in long-duration space flight, and to gain working experience in planning for and executing research on a long-duration space platform. The Phase 1 program was to provide the US early experience prior to the construction and operation of the International Space Station (Phase 2 and 3). While it can be argued that Mir and ISS are different platforms and that programmatically Phase 1 and ISS are organized differently, it is also clear that many aspects of operating a long-duration research program are platform independent. This can be demonstrated by a review of lessons learned from Skylab, a US space station program of the mid-1970s, many of which were again "learned" on Mir and are being "learned" on ISS. Among these are optimum crew training strategies, on-orbit crew operations, ground support, medical operations and crew psychological support, and safety certification processes. PMID:15835035

    2012-01-01

    NASA's Constellation program provided a unique testbed for Human Systems Integration (HSI) as a fundamental element of the Systems Engineering process. Constellation was the first major program to have HSI mandated by NASA's Human Rating document. Proper HSI is critical to the success of any project that relies on humans to function as operators, maintainers, or controllers of a system. HSI improves mission, system and human performance, significantly reduces lifecycle costs, lowers risk and minimizes re-design. Successful HSI begins with sufficient project schedule dedicated to the generation of human systems requirements, but is by no means solely a requirements management process. A top-down systems engineering process that recognizes throughout the organization, human factors as a technical discipline equal to traditional engineering disciplines with authority for the overall system. This partners with a bottoms-up mechanism for human-centered design and technical issue resolution. The Constellation Human Systems Integration Group (HSIG) was a part of the Systems Engineering and Integration (SE&I) organization within the program office, and existed alongside similar groups such as Flight Performance, Environments & Constraints, and Integrated Loads, Structures and Mechanisms. While the HSIG successfully managed, via influence leadership, a down-and-in Community of Practice to facilitate technical integration and issue resolution, it lacked parallel top-down authority to drive integrated design. This presentation will discuss how HSI was applied to Constellation, the lessons learned and best practices it revealed, and recommendations to future NASA program and project managers. This presentation will discuss how Human Systems Integration (HSI) was applied to NASA's Constellation program, the lessons learned and best practices it revealed, and recommendations to future NASA program and project managers on how to accomplish this critical function.

    Hawaii`s extensive renewable resources, limited access to conventional fuels, and its isolated electrical grids all combine to provide an opportunity to clearly observe the development and implementation of renewable energy processes, technologies, and materials. Hawaii is distinctive in its electrical power usage since it is an island chain with isolated grid systems that range in size from less than 5 Megawatts to over 1.5 Gigawatts and also has many off grid dwellings and at least one isolated village system. However, it has been noted that lessons learned from Hawaii`s early experiences in trying to utilize renewable energy have a great deal in common with problems encountered by mainland utilities trying to do the same thing. Furthermore, conditions in Hawaii are very similar to those in many tropical and semitropical locations in the Pacific and Southeast Asia. Hence, Hawaii`s renewable energy experience is shared here in the hope that it may prove useful to others. This review is the second part of a two part series that describes the progress of renewable energy in the state of Hawaii. The steps taken in Hawaii with regards to ocean thermal energy conversion (OTEC), wave energy, photovoltaics (PV), solar thermal water heating, hydroelectric, and geothermal technologies over the past 20 years are reviewed. Conclusions drawn from Hawaii`s renewable energy experience are summarized in a list of lessons learned that are provided for the interest of those who may be carrying out similar efforts in other locations. 64 refs., 3 figs., 7 tabs.

    Minimally invasive esophagectomy with intrathoracic dissection and anastomosis is increasingly performed. Our objectives are to report our operative technique, early results and lessons learned. This is a retrospective review of 85 consecutive patients who were scheduled for minimally invasive Ivor Lewis esophagectomy (laparoscopic or robotic abdominal and robotic chest) for esophageal cancer. Between 4/2011 and 3/2015, 85 (74 men, median age: 63) patients underwent robotic Ivor Lewis esophageal resection. In all, 64 patients (75%) had preoperative chemoradiotherapy, 99% had esophageal cancer, and 99% had an R0 resection. There were no abdominal or thoracic conversions for bleeding. There was 1 abdominal conversion for the inability to completely staple the gastric conduit. The mean operative time was 6 hours, median blood loss was 35ml (no intraoperative transfusions), median number of resected lymph nodes was 22, and median length of stay was 8 days. Conduit complications (anastomotic leak or conduit ischemia) occurred in 6 patients. The 30 and 90-day mortality were 3/85 (3.5%) and 9/85 (10.6%), respectively. Initial poor results led to protocol changes via root cause analysis: longer rehabilitation before surgery, liver biopsy in patients with history of suspected cirrhosis, and refinements to conduit preparation and anastomotic technique. Robotic Ivor Lewis esophagectomy for cancer provides an R0 resection with excellent lymph node resection. Our preferred port placement and operative techniques are described. Disappointingly high thoracic conduit problems and 30 and 90-day mortality led to lessons learned and implementation of change which are shared. PMID:27568155

    The Open Science Grid (OSG) supports a diverse community of new and existing users in adopting and making effective use of the Distributed High Throughput Computing (DHTC) model. The LHC user community has deep local support within the experiments. For other smaller communities and individual users the OSG provides consulting and technical services through the User Support area. We describe these sometimes successful and sometimes not so successful experiences and analyze lessons learned that are helping us improve our services. The services offered include forums to enable shared learning and mutual support, tutorials and documentation for new technology, and troubleshooting of problematic or systemic failure modes. For new communities and users, we bootstrap their use of the distributed high throughput computing technologies and resources available on the OSG by following a phased approach. We first adapt the application and run a small production campaign on a subset of “friendly” sites. Only then do we move the user to run full production campaigns across the many remote sites on the OSG, adding to the community resources up to hundreds of thousands of CPU hours per day. This scaling up generates new challenges - like no determinism in the time to job completion, and diverse errors due to the heterogeneity of the configurations and environments - so some attention is needed to get good results. We cover recent experiences with image simulation for the Large Synoptic Survey Telescope (LSST), small-file large volume data movement for the Dark Energy Survey (DES), civil engineering simulation with the Network for Earthquake Engineering Simulation (NEES), and accelerator modeling with the Electron Ion Collider group at BNL. We will categorize and analyze the use cases and describe how our processes are evolving based on lessons learned.

    The authors identify a number of lessons to be learned regarding implementing a knowledge management system in hospitals. Building on the diffusion of innovations model, the authors address the development and implementation of a staffing productivity system designed to anticipate future hospital staffing needs. They describe the methodology behind the daily staff management system, efforts to market the system, and the implementation process and subsequent discontinuance of the system in a few early adopter hospitals. The authors address a number of principles of diffusion of innovations in the context of a complex adaptive system and provide insights into why some knowledge management systems fail. PMID:18450559

  5. Learning, Misallocation, and Technology Adoption: Evidence from New Malaria Therapy in Tanzania

    2014-01-01

    I study how the misallocation of new technology to individuals who have low ex post returns to its use affects learning and adoption behavior. I focus on antimalarial treatment, which is frequently over-prescribed in many low-income country contexts where diagnostic tests are inaccessible. I show that misdiagnosis reduces average therapeutic effectiveness, because only a fraction of adopters actually have malaria, and slows the rate of social learning due to increased noise. I use data on adoption choices, the timing and duration of fever episodes, and individual blood slide confirmations of malarial status from a pilot study for a new malaria therapy in Tanzania to show that individuals whose reference groups experienced fewer misdiagnoses exhibited stronger learning effects and were more likely to adopt.

    In appropriate physiological milieux proteins spontaneously fold into their functional three-dimensional structures. The amino acid sequences of functional proteins contain all the information necessary to specify the folds. This remarkable observation has spawned research aimed at answering two major questions. (1) Of all the conceivable structures that a protein can adopt, why is the ensemble of native-like structures the most favorable? (2) What are the paths by which proteins manage to robustly and reproducibly fold into their native structures? Anfinsen's thermodynamic hypothesis has guided the pursuit of answers to the first question whereas Levinthal's paradox has influenced the development of models for protein folding dynamics. Decades of work have led to significant advances in the folding problem. Mean-field models have been developed to capture our current, coarse grain understanding of the driving forces for protein folding. These models are being used to predict three-dimensional protein structures from sequence and stability profiles as a function of thermodynamic and chemical perturbations. Impressive strides have also been made in the field of protein design, also known as the inverse folding problem, thereby testing our understanding of the determinants of the fold specificities of different sequences. Early work on protein folding pathways focused on the specific sequence of events that could lead to a simplification of the search process. However, unifying principles proved to be elusive. Proteins that show reversible two-state folding-unfolding transitions turned out to be a gift of natural selection. Focusing on these simple systems helped researchers to uncover general principles regarding the origins of cooperativity in protein folding thermodynamics and kinetics. On the theoretical front, concepts borrowed from polymer physics and the physics of spin glasses led to the development of a framework based on energy landscape theories. These

    A growing number of low and middle income nations (LMCs) have adopted some sort of system for environmental impact assessment (EIA). However, generally many of these EIA systems are characterised by a low performance in terms of timely information dissemination, monitoring and enforcement after licencing. Donor actors (such as the World Bank) have attempted to contribute to a higher performance of EIA systems in LMCs by intervening at two levels: the project level (e.g. by providing scoping advice or EIS quality review) and the system level (e.g. by advising on EIA legislation or by capacity building). The aims of these interventions are environmental protection in concrete cases and enforcing the institutionalisation of environmental protection, respectively. Learning by actors involved is an important condition for realising these aims. A relatively underexplored form of learning concerns learning at EIA system-level via project level donor interventions. This 'indirect' learning potentially results in system changes that better fit the specific context(s) and hence contribute to higher performances. Our exploratory research in Ghana and the Maldives shows that thus far, 'indirect' learning only occurs incidentally and that donors play a modest role in promoting it. Barriers to indirect learning are related to the institutional context rather than to individual characteristics. Moreover, 'indirect' learning seems to flourish best in large projects where donors achieved a position of influence that they can use to evoke reflection upon system malfunctions. In order to enhance learning at all levels donors should thereby present the outcomes of the intervention elaborately (i.e. discuss the outcomes with a large audience), include practical suggestions about post-EIS activities such as monitoring procedures and enforcement options and stimulate the use of their advisory reports to generate organisational memory and ensure a better information dissemination.

  10. Lessons Learned from Ares I Upper Stage Structures and Thermal Design

    2012-01-01

    The Ares 1 Upper Stage was part of the vehicle intended to succeed the Space Shuttle as the United States manned spaceflight vehicle. Although the Upper Stage project was cancelled, there were many lessons learned that are applicable to future vehicle design. Lessons learned that are briefly detailed in this Technical Memorandum are for specific technical areas such as tank design, common bulkhead design, thrust oscillation, control of flight and slosh loads, purge and hazardous gas system. In addition, lessons learned from a systems engineering and vehicle integration perspective are also included, such as computer aided design and engineering, scheduling, and data management. The need for detailed systems engineering in the early stages of a project is emphasized throughout this report. The intent is that future projects will be able to apply these lessons learned to keep costs down, schedules brief, and deliver products that perform to the expectations of their customers.

    2010-01-01

    Node 1 flew to the International Space Station (ISS) on Flight 2A during December 1998. To date the National Aeronautics and Space Administration (NASA) has learned a lot of lessons from this module based on its history of approximately two years of acceptance testing on the ground and currently its twelve years on-orbit. This paper will provide an overview of the ISS Environmental Control and Life Support (ECLS) design of the Node 1 Temperature and Humidity Control (THC) subsystem and it will document some of the lessons that have been learned to date for this subsystem and it will document some of the lessons that have been learned to date for these subsystems based on problems prelaunch, problems encountered on-orbit, and operational problems/concerns. It is hoped that documenting these lessons learned from ISS will help in preventing them in future Programs. 1
