The entire procedure of incorporating the requirements and goals of a space flight project into integrated, time ordered sequences of spacecraft commands, is called the uplink process. The Uplink Process Control Task (UPCT) was created to examine the uplink process and determine ways to improve it. The Problem Statement Language/Problem Statement Analyzer (PSL/PSA) designed to assist the designer/analyst/engineer in the preparation of specifications of an information system is used as a supporting tool to aid in the analysis. Attention is given to a definition of the uplink process, the definition of PSL/PSA, the construction of a PSA database, the value of analysis to the study of the uplink process, and the PSL/PSA lessons learned.

Lessons learned enhancing EPICS CA for LANSCE timed and flavored data

International Nuclear Information System (INIS)

Hill, Jeffrey O.

2009-01-01

A previous paper described an upgrade to EPICS enabling client side tools at LANSCE to receive subscription updates filtered selectively to match a logical configuration of LANSCE beam gates, as configured by the control room. The upgrade required fundamental changes in the EPICS core components. First, the event queue in the EPICS server was upgraded to buffer record (function block) and device specific parameters accessed generically via software interfaces for introspection of 3rd party data. In contrast, event queues in previous versions of EPICS were strictly limited to buffering only value, timestamp, and alarm status tuples. Second, the Channel Access server is being upgraded to filter subscription updates. In this follow on paper some necessary design changes mid-project and the lessons learned during the software development will be described.

After the Fukushima event (March 2011) the IAEA has started an action to review and revise, if necessary, all Safety Standards to take into consideration the lessons learned from the accident. The Safety Standards that need to be revised have been identified. A Prioritization Approach has been established: The first priority is to review safety guides applicable for NPPs and spent fuel storage with focus on the measures for the prevention and mitigation of severe accident due to external hazards - ● Regulatory framework, Safety assessment, Management system, Radiation protection and Emergency Preparedness and response; ● Sitting, Design, Operation of NPPs ● Decommissioning and Waste Management. Original sources for lessons learned: IAE fact Finding Mission, Japan´s report to the Ministerial Conference, INSAG Report, etc. Later, other lesson sources considered

Lessons learned related to packaging and transportation

Wallen, C.

1995-01-01

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

Wray, Richard B.

1991-01-01

A hybrid requirements analysis methodology was developed, based on the practices actually used in developing a Space Generic Open Avionics Architecture. During the development of this avionics architecture, a method of analysis able to effectively define the requirements for this space avionics architecture was developed. In this methodology, external interfaces and relationships are defined, a static analysis resulting in a static avionics model was developed, operating concepts for simulating the requirements were put together, and a dynamic analysis of the execution needs for the dynamic model operation was planned. The systems engineering approach was used to perform a top down modified structured analysis of a generic space avionics system and to convert actual program results into generic requirements. CASE tools were used to model the analyzed system and automatically generate specifications describing the model's requirements. Lessons learned in the use of CASE tools, the architecture, and the design of the Space Generic Avionics model were established, and a methodology notebook was prepared for NASA. The weaknesses of standard real-time methodologies for practicing systems engineering, such as Structured Analysis and Object Oriented Analysis, were identified.

Constellation Program Lessons Learned. Volume 2; Detailed Lessons Learned

Rhatigan, Jennifer; Neubek, Deborah J.; Thomas, L. Dale

2011-01-01

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

A Worldwide Production Grid Service Built on EGEE and OSG Infrastructures Lessons Learnt and Long-term Requirements

International Nuclear Information System (INIS)

Shiers, J.; Dimou, M.; Mendez Lorenzo, P.

2007-01-01

Using the Grid Infrastructures provided by EGEE, OSG and others, a worldwide production service has been built that provides the computing and storage needs for the 4 main physics collaborations at CERN's Large Hadron Collider (LHC). The large number of users, their geographical distribution and the very high service availability requirements make this experience of Grid usage worth studying for the sake of a solid and scalable future operation. This service must cater for the needs of thousands of physicists in hundreds of institutes in tens of countries. A 24x7 service with availability of up to 99% is required with major service responsibilities at each of some ten T ier1 a nd of the order of one hundred T ier2 s ites. Such a service - which has been operating for some 2 years and will be required for at least an additional decade - has required significant manpower and resource investments from all concerned and is considered a major achievement in the field of Grid computing. We describe the main lessons learned in offering a production service across heterogeneous Grids as well as the requirements for long-term operation and sustainability. (Author)

One of the more challenging aspects of software development is the ability to verify and validate the functional software requirements dictated by the Software Requirements Specification (SRS) and the Software Detail Design (SDD). Insuring the software has achieved the intended requirements is the responsibility of the Software Quality team and the Software Test team. The utilization of Timeliner-TLX(sup TM) Auto- Procedures for relocating ground operations positions to ISS automated on-board operations has begun the transition that would be required for manned deep space missions with minimal crew requirements. This transition also moves the auto-procedures from the procedure realm into the flight software arena and as such the operational requirements and testing will be more structured and rigorous. The autoprocedures would be required to meet NASA software standards as specified in the Software Safety Standard (NASASTD- 8719), the Software Engineering Requirements (NPR 7150), the Software Assurance Standard (NASA-STD-8739) and also the Human Rating Requirements (NPR-8705). The Autonomous Fluid Transfer System (AFTS) test-bed utilizes the Timeliner-TLX(sup TM) Language for development of autonomous command and control software. The Timeliner-TLX(sup TM) system has the unique feature of providing the current line of the statement in execution during real-time execution of the software. The feature of execution line number internal reporting unlocks the capability of monitoring the execution autonomously by use of a companion Timeliner-TLX(sup TM) sequence as the line number reporting is embedded inside the Timeliner-TLX(sup TM) execution engine. This negates I/O processing of this type data as the line number status of executing sequences is built-in as a function reference. This paper will outline the design and capabilities of the AFTS Autonomous Requirements Tracker, which traces and logs SRS requirements as they are being met during real-time execution of the

Next generation nuclear power plants and digital upgrades to the existing nuclear fleet introduce potential human performance issues in the control room. Safe application of new technologies calls for a thorough understanding of how those technologies affect human performance and in turn, plant safety. In support of advancing human factors for small modular reactors and light water reactor sustainability, the Idaho National Laboratory (INL) has developed a reconfigurable simulation laboratory capable of testing human performance in multiple nuclear power plant (NPP) control room simulations. This paper discusses the laboratory infrastructure and capabilities, the laboratory's staffing requirements, lessons learned, and the researcher's approach to measuring human performance in the simulation lab.

Lessons of nuclear robot history

Severe accidents occurred at Fukushima Daiichi Nuclear Power Station stirred up people's great expectation of nuclear robot's deployment. However unexpected nuclear disaster, especially rupture of reactor building caused by core meltdown and hydrogen explosion, made it quite difficult to introduce nuclear robot under high radiation environment to cease accidents and dispose damaged reactor. Robotics Society of Japan (RSJ) set up committee to look back upon lessons learned from 50 year's past experience of nuclear robot development and summarized 'Lessons of nuclear robot history', which was shown on the home page website of RSJ. This article outlined it with personal comment. History of nuclear robot developed for inspection and maintenance at normal operation and for specific required response at nuclear accidents was reviewed with many examples at home and abroad for TMI, Chernobyl and JCO accidents. Present state of Fukushima accident response robot's introduction and development was also described with some comments on nuclear robot development from academia based on lessons. (T. Tanaka)

The Employed Neurosurgeon: Essential Lessons.

Science.gov (United States)

Benzil, Deborah L; Zusman, Edie E

2017-04-01

Neurosurgeons are highly specialized surgeons whose pride is mastery of the complexity of form and function that is the nervous system and then knowing when and how these require surgical intervention. Following years of arduous postgraduate education, neurosurgeons enter the world of practice that is not only daunting in its intricacies of regulations, mandates, and unknown business practices, but also changing at a meteoric pace. Overwhelmingly, graduating residents and fellows are choosing to practice as employed physicians, a trend that is new in its magnitude and also changed because of the rapid evolution of large health systems. Case studies of challenges other employed surgical specialists have faced can provide critical and important education for any neurosurgeon in this arena. As with the lessons of all case studies, the teachings are remarkably universal, but how those lessons apply to an individual's specific situation will require personalized adaptation.

During the past four years, the Department of Energy -- Savannah River Operations Office and the Westinghouse Savannah River Company (WSRC) Environmental Restoration (ER) Program completed various activities ranging from waste site investigations to closure and post closure projects. Critiques for lessons learned regarding project activities are performed at the completion of each project milestone, and this critique interval allows for frequent recognition of lessons learned. In addition to project related lessons learned, ER also performs lessons learned critiques. T'he Savannah River Site (SRS) also obtains lessons learned information from general industry, commercial nuclear industry, naval nuclear programs, and other DOE sites within the complex. Procedures are approved to administer the lessons learned program, and a database is available to catalog applicable lessons learned regarding environmental remediation, restoration, and administrative activities. ER will continue to use this database as a source of information available to SRS personnel

PUREX/UO3 Facilities deactivation lessons learned history

Energy Technology Data Exchange (ETDEWEB)

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

Implementation lessons: • Technology alone does not necessarily lead to improvement in health service delivery, in contrast to the common assumption that advanced technology goes hand in hand with progress. • Implementation of electronic medical record (EMR) systems is a complex, resource-intensive process that, in addition to software, hardware, and human resource investments, requires careful planning, change management skills, adaptability, and continuous engagement of stakeholders. • Research requirements and goals must be balanced with service delivery needs when determining how much information is essential to collect and who should be interfacing with the EMR system. • EMR systems require ongoing monitoring and regular updates to ensure they are responsive to evolving clinical use cases and research questions. • High-quality data and analyses are essential for EMRs to deliver value to providers, researchers, and patients.

David Minor

2014-07-01

Full Text Available In the spring of 2011, the UC San Diego Research Cyberinfrastructure (RCI Implementation Team invited researchers and research teams to participate in a research curation and data management pilot program. This invitation took the form of a campus-wide solicitation. More than two dozen applications were received and, after due deliberation, the RCI Oversight Committee selected five curation-intensive projects. These projects were chosen based on a number of criteria, including how they represented campus research, varieties of topics, researcher engagement, and the various services required. The pilot process began in September 2011, and will be completed in early 2014. Extensive lessons learned from the pilots are being compiled and are being used in the on-going design and implementation of the permanent Research Data Curation Program in the UC San Diego Library. In this paper, we present specific implementation details of these various services, as well as lessons learned. The program focused on many aspects of contemporary scholarship, including data creation and storage, description and metadata creation, citation and publication, and long term preservation and access. Based on the lessons learned in our processes, the Research Data Curation Program will provide a suite of services from which campus users can pick and choose, as necessary. The program will provide support for the data management requirements from national funding agencies.

The lessons learned from the radiological accident of Goiania in 1987 derived from the observations from the Regulatory Agency which was in charge of the decontamination tasks may be consolidated into four classes: Preventive Actions, characterised as those that aim to minimise the probability of occurrence of a radiological accident; Minimisation of time between the moment of the accident occurrence and the beginning of intervention, in case a radiological accident does occur, despite all preventive measures; Intervention, which is correlated to the type of installation, its geographical location, the social classes involved and their contamination vectors; and Follow up, for which well established rules to allow continuing monitoring of the victims and rebuilding of homes are necessary. The greatest lesson of all was the need for integration of the professionals involved, from all organizations. (author)

Lessons Learned In Developing The VACIS Products

Orphan, Victor J.

2011-01-01

SAIC's development of VACIS provides useful 'lessons learned' in bridging the gap from an idea to a security or contraband detection product. From a gamma densitometer idea for solving a specific Customs Service (CS) requirement (detection of drugs in near-empty tanker trucks) in mid-1990's, SAIC developed a broad line of vehicle and cargo inspections systems (over 500 systems deployed to date) based on a gamma-ray radiographic imaging technique. This paper analyzes the reasons for the successful development of VACIS and attempts to identify ''lessons learned'' useful for future security and contraband detection product developments.

Kostenbader, Tracy C.

Due to the logistics of guided-inquiry lesson, students learn to problem solve and develop critical thinking skills. This mixed-methods study analyzed the students' attitudes towards science during inquiry lessons. My quantitative results from a repeated measures survey showed no significant difference between student attitudes when taught with either structured-inquiry or guided-inquiry lessons. The qualitative results analyzed through a constant-comparative method did show that students generate positive interest, critical thinking and low level stress during guided-inquiry lessons. The qualitative research also gave insight into a teacher's transition to guided-inquiry. This study showed that with my students, their attitudes did not change during this transition according to the qualitative data however, the qualitative data did how high levels of excitement. The results imply that students like guided-inquiry laboratories, even though they require more work, just as much as they like traditional laboratories with less work and less opportunity for creativity.

The US DOE Office of Legacy Management (LM) is the long-term steward for 90 sites remediated under numerous regulatory regimes including the Formerly Utilized Sites Remedial Action Program (FUSRAP) sites. In addition, LM holds considerable historical information, gathered in the 1970s, to determine site eligibility for remediation under FUSRAP. To date, 29 FUSRAP sites are in LM’s inventory of sites for long-term surveillance and maintenance (LTS&M), and 25 are with the US Army Corps of Engineers (USACE) for remediation or in the process of being transitioned to LM. It is forecasted that 13 FUSRAP sites will transfer from the USACE to LM over the next 10 years; however, the timing of the transfers is strongly dependent upon federal funding of the ongoing remedial actions. Historically, FUSRAP sites were generally cleaned up for “unrestricted” industrial use or remediated to the “cleanup standards” at that time, and their use remained unchanged. Today, these sites as well as the adjacent properties are now changing or envisioned to have changes in land use, typically from industrial to commercial or residential uses. The implication of land-use change affects DOE’s LTS&M responsibility for the sites under LM stewardship as well as the planning for the additional sites scheduled to transition in time. Coinciding with land-use changes at or near FUSRAP sites is an increased community awareness of these sites. As property development increases near FUSRAP sites, the general public and interested stakeholders regularly inquire about the sufficiency of cleanups that impact their neighborhoods and communities. LM has used this experience to address a series of lessons learned to improve our program management in light of the changing conditions of our sites. We describe these lessons learned as (1) improved stakeholder relations, (2) enhanced LTS&M requirements for the sites, and (3) greater involvement in the transition process.

Do Lessons in Nature Boost Subsequent Classroom Engagement? Refueling Students in Flight

Full Text Available Teachers wishing to offer lessons in nature may hold back for fear of leaving students keyed up and unable to concentrate in subsequent, indoor lessons. This study tested the hypothesis that lessons in nature have positive—not negative—aftereffects on subsequent classroom engagement. Using carefully matched pairs of lessons (one in a relatively natural outdoor setting and one indoors, we observed subsequent classroom engagement during an indoor instructional period, replicating these comparisons over 10 different topics and weeks in the school year, in each of two third grade classrooms. Pairs were roughly balanced in how often the outdoor lesson preceded or followed the classroom lesson. Classroom engagement was significantly better after lessons in nature than after their matched counterparts for four of the five measures developed for this study: teacher ratings; third-party tallies of “redirects” (the number of times the teacher stopped instruction to direct student attention back onto the task at hand; independent, photo-based ratings made blind to condition; and a composite index each showed a nature advantage; student ratings did not. This nature advantage held across different teachers and held equally over the initial and final 5 weeks of lessons. And the magnitude of the advantage was large. In 48 out of 100 paired comparisons, the nature lesson was a full standard deviation better than its classroom counterpart; in 20 of the 48, the nature lesson was over two standard deviations better. The rate of “redirects” was cut almost in half after a lesson in nature, allowing teachers to teach for longer periods uninterrupted. Because the pairs of lessons were matched on teacher, class (students and classroom, topic, teaching style, week of the semester, and time of day, the advantage of the nature-based lessons could not be attributed to any of these factors. It appears that, far from leaving students too keyed up to concentrate

This approach shows that Munich is the end point of a constitutive history that begins in the failure of the Versailles treaty to create a durable European order following the First World War. The Munich lesson is thus......The article investigates the concept of lessons in IR. By means of a constructivist critique of the 'lessons literature', the article analyses one of the most important of IR lessons: that of Munich. Examining how the Munich lesson came about, the article shows the praxeological nature of lessons...... one element of the lesson of Versailles, which is a praxeology that defines how the West is to make peace, and against whom peace must be defended.

A Worldwide Production Grid Service Built on EGEE and OSG Infrastructures – Lessons Learnt and Long-term Requirements

CERN Document Server

Shiers, J; Dimou, M; CERN. Geneva. IT Department

2007-01-01

Using the Grid Infrastructures provided by EGEE, OSG and others, a worldwide production service has been built that provides the computing and storage needs for the 4 main physics collaborations at CERN's Large Hadron Collider (LHC). The large number of users, their geographical distribution and the very high service availability requirements make this experience of Grid usage worth studying for the sake of a solid and scalable future operation. This service must cater for the needs of thousands of physicists in hundreds of institutes in tens of countries. A 24x7 service with availability of up to 99% is required with major service responsibilities at each of some ten "Tier1" and of the order of one hundred "Tier2" sites. Such a service - which has been operating for some 2 years and will be required for at least an additional decade - has required significant manpower and resource investments from all concerned and is considered a major achievement in the field of Grid computing. We describe the main lessons...

Lesson study: Professional development and its impact on science teacher self-efficacy

Science.gov (United States)

Roberts, Megan Rae

This study focuses on an analysis of a professional development program known as lesson study via data obtained during an in-service professional development program for secondary school science teachers. The purpose of this study was to examine the self-efficacy beliefs of one group of science teachers related to their experiences in a lesson study. Another purpose for this research, aligned with the first, included a theoretical analysis of the lesson study construct to see if its design promoted positive self-efficacy beliefs of its participants. The research is framed within the context of social constructivism and self-efficacy and is qualitative in nature and utilized descriptive analysis as a means of research. Case studies were conducted detailing two of the six participants. Data sources included researcher field notes and transcriptions of all planning and debriefing sessions; individual interviews with each participant and the schools' principal; a participant questionnaire, and the Science Teaching Efficacy Belief Instrument. Themes that emerged included the positive perceptions of lesson study as a collaborative and teacher-centered experience; the understanding that lesson study can instill a sense of professionalism to those who participate in the process; the sense that discussing student learning using objective observations from classroom is a powerful way to assess learning and uncover personal teacher beliefs; and the insight that the time commitment that lesson study requires can inhibit teachers and schools from sustaining it as a form of on-going professional development. Although these themes are consistent with the research on lesson study in Japan and elsewhere in the United States, they also extend the research on self-efficacy and science teacher professional development. In the end, this study supported some of the conclusions of the self-efficacy research as it relates to professional development while also adding that interpersonal

Effective Lesson Planning: Field Trips in the Science Curriculum

Rieger, C. R.

2010-10-01

Science field trips can positively impact and motivate students. However, if a field trip is not executed properly, with appropriate preparation and follow-up reinforcement, it can result in a loss of valuable educational time and promote misconceptions in the students. This study was undertaken to determine if a classroom lesson before an out-of-the-classroom activity would affect learner gain more or less than a lesson after the activity. The study was based on the immersive theater movie ``Earth's Wild Ride'' coupled with a teacher-led Power Point lesson. The participants in the study were students in a sixth grade physical science class. The order of lessons showed no detectable effect on final learner outcomes. Based on pre- and post-testing, improvement in mean learning gain came from the teacher-led lesson independent of the movie. The visit to the immersive theater, however, had significant positive effects that did not show up in the quantitative results of the testing.

Verifying real-time systems against scenario-based requirements

Larsen, Kim Guldstrand; Li, Shuhao; Nielsen, Brian

2009-01-01

We propose an approach to automatic verification of real-time systems against scenario-based requirements. A real-time system is modeled as a network of Timed Automata (TA), and a scenario-based requirement is specified as a Live Sequence Chart (LSC). We define a trace-based semantics for a kernel...... subset of the LSC language. By equivalently translating an LSC chart into an observer TA and then non-intrusively composing this observer with the original system model, the problem of verifying a real-time system against a scenario-based requirement reduces to a classical real-time model checking...

Lessons learned on digital systems safety

Sivertsen, Terje

2005-06-01

A decade ago, in 1994, lessons learned from Halden research activities on digital systems safety were summarized in the reports HWR-374 and HWR-375, under the title 'A Lessons Learned Report on Software Dependability'. The reports reviewed all activities made at the Halden Project in this field since 1977. As such, the reports provide a wealth of information on Halden research. At the same time, the lessons learned from the different activities are made more accessible to the reader by being summarized in terms of results, conclusions and recommendations. The present report provides a new lessons learned report, covering the Halden Project research activities in this area from 1994 to medio 2005. As before, the emphasis is on the results, conclusions and recommendations made from these activities, in particular how they can be utilized by different types of organisations, such as licensing authorities, safety assessors, power companies, and software developers. The contents of the report have been edited on the basis of input from a large number of Halden work reports, involving many different authors. Brief summaries of these reports are included in the last part of the report. (Author)

Connecting polar research to NGSS STEM classroom lessons

Science.gov (United States)

Brinker, R.; Kast, D.

2016-12-01

Next Generation Science Standards (NGSS) are designed to bring consistent, rigorous science teaching across the United States. Topics are categorized as Performance Expectations (PE), Disciplinary Core Ideas (DCI), Cross-Cutting Concepts (CCC), and Science and Engineering Practices (SEP). NGSS includes a focus on environmental science and climate change across grade levels. Earth and planetary sciences are required at the high school level. Integrating polar science lessons into NGSS classrooms brings relevant, rigorous climate change curriculum across grade levels. Polar science provides opportunities for students to use current data during lessons, conduct their own field work, and collaborate with scientists. Polar science provides a framework of learning that is novel to most students. Inquiry and engagement are high with polar science lessons. Phenomenon related to polar science provide an excellent tool for science teachers to use to engage students in a lesson, stimulate inquiry, and promote critical thinking. When taught effectively, students see the connections between their community, polar regions and climate change, regardless of where on the planet students live. This presentation describes examples of how to effectively implement NGSS lessons by incorporating polar science lessons and field research. Examples of introductory phenomenon and aligned PEs, CCCs, DCIs, and SEPs are given. Suggested student activities, assessments, examples of student work, student research, labs, and PolarTREC fieldwork, use of current science data, and connections to scientists in the field are provided. The goals of the presentation are to give teachers a blueprint to follow when implementing NGSS lessons, and give scientists an understanding of the basics of NGSS so they may be better able to relate their work to U.S. science education and be more effective communicators of their science findings.

Lessons learned from the NRU vessel leak repair and return to service projects

International Nuclear Information System (INIS)

Heeney, P.; Turcotte, J.

2011-01-01

In May 2009 the National Research Universal (NRU) reactor was shut down due to a small leak detected from the reactor vessel into the annulus surrounding the reactor. What ensued was a challenging, yet successful, 15 month long Repair and Return to Service Outage. This Repair and Return to Service Outage presented many first-of-a-kind challenges that provide learning opportunities which have been incorporated into subsequent planned outages. These lessons learned are invaluable tools to be used in the planning and execution of future outages. Following the repair of the NRU vessel, AECL was required to conduct annual inspections of the vessel wall. These inspections require an annual Extended Outage (up to 4 weeks in length). A planned Extended Outage was conducted in May/June 2011 and provided an opportunity to implement some of the lessons learned during the Repair and Return to Service Outage. Lessons learned from that Extended Outage have been incorporated in the subsequent monthly maintenance outages, with lessons learned sessions being held after each outage to ensure that the execution of outages is constantly improving.

Haby Michelle M

2012-01-01

Full Text Available Abstract Background Interest in community-based interventions (CBIs for health promotion is increasing, with a lot of recent activity in the field. This paper aims, from a state government perspective, to examine the experience of funding and managing six obesity prevention CBIs, to identify lessons learned and to consider the implications for future investment. Specifically, we focus on the planning, government support, evaluation, research and workforce development required. Methods The lessons presented in this paper come from analysis of key project documents, the experience of the authors in managing the projects and from feedback obtained from key program stakeholders. Results CBIs require careful management, including sufficient planning time and clear governance structures. Selection of interventions should be based on evidence and tailored to local needs to ensure adequate penetration in the community. Workforce and community capacity must be assessed and addressed when selecting communities. Supporting the health promotion workforce to become adequately skilled and experienced in evaluation and research is also necessary before implementation. Comprehensive evaluation of future projects is challenging on both technical and affordability grounds. Greater emphasis may be needed on process evaluation complemented by organisation-level measures of impact and monitoring of nutrition and physical activity behaviours. Conclusions CBIs offer potential as one of a mix of approaches to obesity prevention. If successful approaches are to be expanded, care must be taken to incorporate lessons from existing and past projects. To do this, government must show strong leadership and work in partnership with the research community and local practitioners.

Lessons learned in wake of WPPSS

Koenen, A.V.; Gillespie, J.W.

1984-01-01

Several fundamentals of public power financial management have become more critical in the wake of the Washington Public Power Supply System (WPPSS) default: the human and financial costs of trying to resolve problems of this complexity after they occur will require an almost unimaginable amount of time and money that could be productively employed elsewhere; the economic feasibility of the project is paramount, and is far more important than its legal security or its attractiveness to utility managers; the ratepayers' ability and willingness to pay is the key security in public power financing; management performance, not promises, will be the measure of the post WPPSS marketplace; financial flexibility is crucial. Using these lessons, the author outlines a five-step program of strategic planning for planning and managing long-term projects

Winds of time: Lessons from Utö in the Stockholm Archipelago, 1990–2001

International Nuclear Information System (INIS)

Fjaestad, Maja

2013-01-01

When investigating the success or failure of different wind power projects, it is essential to take into account how they were historically situated. This study focuses on attempts to develop wind power in an archipelago setting, at Utö in Sweden. It has been argued that the development of Swedish wind power slowed during the 1990s; by revisiting the early days of wind power, looking at resistance and support, and connecting success factors, this can be further investigated. Whereas earlier research pointed out institutional conditions and site-specific conditions as crucial for successful wind power development and acceptance, the picture can be made more complete by discussing how wind power projects are affected by time-specific historical conditions. In the case of Utö, these can partly be associated with a newly launched political support program that gave the project political legitimacy and added a “pioneering spirit” to the endeavor. Conversely, when wind power is not seen as “pioneering” or “experimental” any more, but as a mere industrial activity, other incentives may need to be offered to municipalities. -- Highlights: •When evaluating wind power projects, the historical context is important to complement the picture. •The case of Utö is tells important lessons of the Swedish early 1990s. •Success factors in this case: political legitimacy, local support, pioneering spirit, promising technology. •This wind power establishment was not seen as a threat to recreation or landscape. •Lessons for today: how to deal with socio-political acceptance when wind power becomes “industrial”

It was broadcasted to all Cuba from March to December 2005, one lesson per week, transmitting three times each lesson, this means 90 hours of broadcasting. It was one of the courses of the Program "University for All", that Educative Channel produced. The Thematic: Sky Coordinates and Constellations; Astronomical Instruments; Solar System; Planets and their Moons; Comets, Asteroids and Meteoroids; Sun; Cosmic Environment and Space Weather; Stars; Galaxy and Quasars; Observable Universe; Life, Intelligent Life and Civilizations in the Universe; and History of Astronomy in Cuba. The professor staff was a group of 5 researchers of the Astronomy Department. They did an effort that each lesson had the best information level with a minimum of mathematical expressions. And were used more than 60 slides and various astronomical films fragments per lesson. To make one lesson was analyzed several astronomical films, selected a group of fragments and pre-edited into various blocks with the TV specialists, later a power point presentation was conformed using all available information on-line and bibliography. Then the lesson was recorded by the TV specialist at the Educative Channel and latter reviewed and improved by one AVID edition. The Course groundwork began in April 2003, with the first list of 12 lessons, later in June was increased to18 lessons, and started the work of "Tabloide" making; it is a journal-type book of 32 pages, equivalent to about 120 normal pages including 64 illustrations. At December 2004 the Course was increased to 30 lessons and the "Tabloide" was send to editor, later 200,000 exemplars was published. Many people followed Course and "Tabloide" was shopped in some months.

Evaluation of World Wide Web-based Lessons for a First Year Dental Biochemistry Course

Dr. Alan E. Levine

2002-11-01

Full Text Available First year dental students at The University of Texas Dental Branch at Houston (Dental Branch are required to take a basic biochemistry course. To facilitate learning and allow student self-assessment of their progress, WWW-based lessons covering intermediary metabolism were developed as a supplement to traditional lectures. Lesson design combined text, graphics, and animations and included learner control, links to other learning resources, and practice exercises and exams with immediate feedback. Results from an on-line questionnaire completed by students in two different classes showed that they completed 50% of the lessons and spent an average of 4 hrs. on-line. A majority of the students either agreed or strongly agreed that practice exercises were helpful, that the ability to control the pace of the lessons was important, that the lesson structure and presentation was easy to follow, that the illustrations, animations, and hyperlinks were helpful, and that the lessons were effective as a review. The very positive response to the WWW-based lessons indicates the usefulness of this approach as a study aid for dental students.

Development of concept-based physiology lessons for biomedical engineering undergraduate students.

Nelson, Regina K; Chesler, Naomi C; Strang, Kevin T

2013-06-01

Physiology is a core requirement in the undergraduate biomedical engineering curriculum. In one or two introductory physiology courses, engineering students must learn physiology sufficiently to support learning in their subsequent engineering courses and careers. As preparation for future learning, physiology instruction centered on concepts may help engineering students to further develop their physiology and biomedical engineering knowledge. Following the Backward Design instructional model, a series of seven concept-based lessons was developed for undergraduate engineering students. These online lessons were created as prerequisite physiology training to prepare students to engage in a collaborative engineering challenge activity. This work is presented as an example of how to convert standard, organ system-based physiology content into concept-based content lessons.

Prioritizing Defence Industry Capabilities: Lessons for Canada from Australia

Directory of Open Access Journals (Sweden)

J. Craig Stone

2014-01-01

Full Text Available A number of Canadian acquisition announcements over the past few years have generated significant debate about a variety of issues like whether or not Canada should have a separate procurement agency, whether or not industrial and regional benefits are appropriate and whether or not Canadian companies should be given preference over international companies. In discussions about improving our procurement process Australia is often used as an example because the nations are generally considered to be similar in size with respect to GDP, population and military. This study examines Australia’s approach to establishing a defence industry policy with a set of Priority Industry Capabilities and how that policy connects with military procurement in order to identify those lessons that might be useful for Canada as it seeks to improve its own procurement process and its relationship with the defence industry. The study looks at some important background information on the Australian experience and then looks more specifically at the most recent articulation of policies in Australia. Although Australia is not without its own challenges, there are a number of lessons that stand out for Canada. This study discusses the lessons for Canada and recommends that government spends the time and effort required to connect a series of related policy documents that provides industry and others with an articulation of what the government of the day intends to do and what their priorities are moving forward. It also recommends a holistic review of the entire procurement process to determine what is working well and what actually needs fixing would be useful.

Cryptography and the Internet: lessons and challenges

Energy Technology Data Exchange (ETDEWEB)

McCurley, K.S.

1996-12-31

The popularization of the Internet has brought fundamental changes to the world, because it allows a universal method of communication between computers. This carries enormous benefits with it, but also raises many security considerations. Cryptography is a fundamental technology used to provide security of computer networks, and there is currently a widespread engineering effort to incorporate cryptography into various aspects of the Internet. The system-level engineering required to provide security services for the Internet carries some important lessons for researchers whose study is focused on narrowly defined problems. It also offers challenges to the cryptographic research community by raising new questions not adequately addressed by the existing body of knowledge. This paper attempts to summarize some of these lessons and challenges for the cryptographic research community.

Lessons on corporate "sustainability" disclosure from Deepwater Horizon.

Science.gov (United States)

Lewis, Sanford

2011-01-01

The BP oil spill highlighted shortcomings of current financial and sustainability reporting standards and practice. "Integrated reporting" aims to combine financial and social/environmental information into a single annual corporate report. But without more stringent standards, integrated reports would neglect substantial risks and, as BP's sustainability reports demonstrate, create false impressions of good practice.To be of value, integration must: 1. Require timely disclosure of enforcement notices, orders and allegations issued by regulators. 2. Require disclosure of credible scientific reports and concerns indicative of potentially catastrophic risks of a company's products and activities, regardless of scientific uncertainty. 3. Require review and disclosures of a firm's safety culture. 4. Require disclosure of any facts or circumstances needed to ensure that the management's self-portrait of its sustainability strategies, goals and progress is not materially misleading.In conducting its misleading reporting, BP largely followed Global Reporting Initiative (GRI) guidelines. GRI is soliciting input, beginning in summer 2011, on how to revise those guidelines. Since GRI may prove a leading source for sustainability disclosure rules in integrating reporting, lessons learned from the BP experience must be applied to the next GRI revisions.

We consider the attributes of a successful engineered material, acknowledging the contributions of composition and processing to properties and performance. We recognize the potential for relevant lessons to be learned from nature, at the same time conceding both the limitations of such lessons and our need to be selective. We then give some detailed attention to the molecular biomimicry of filamentous phage, the process biomimicry of silk and the structure biomimicry of hippopotamus 'sweat', in each case noting that the type of lesson now being learned is not the same as the potential lesson that originally motivated the study.

To design a usable HAMMLAB 2000, lessons learned from use of the existing HAMMLAB must be documented. User suggestions are important and must be taken into account. Different roles in HAMMLAB experimental sessions are identified, and major functions of each role were specified. A series of questionnaires were developed and administered to different users of HAMMLAB, each tailored to the individual job description. The results of those questionnaires are included in this report. Previous HAMMLAB modification recommendations were also reviewed, to provide input to this document. A trial experimental session was also conducted, to give an overview of the tasks in HAMMLAB. (author)

Constellation Program: Lessons Learned. Volume 1; Executive Summary

Science.gov (United States)

Rhatigan, Jennifer L. (Editor)

2011-01-01

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

The world is on the verge of achieving global polio eradication. During >25 years of operations, the Global Polio Eradication Initiative (GPEI) has mobilized and trained millions of volunteers, social mobilizers, and health workers; accessed households untouched by other health initiatives; mapped and brought health interventions to chronically neglected and underserved communities; and established a standardized, real-time global surveillance and response capacity. It is important to document the lessons learned from polio eradication, especially because it is one of the largest ever global health initiatives. The health community has an obligation to ensure that these lessons and the knowledge generated are shared and contribute to real, sustained changes in our approach to global health. We have summarized what we believe are 10 leading lessons learned from the polio eradication initiative. We have the opportunity and obligation to build a better future by applying the lessons learned from GPEI and its infrastructure and unique functions to other global health priorities and initiatives. In so doing, we can extend the global public good gained by ending for all time one of the world's most devastating diseases by also ensuring that these investments provide public health dividends and benefits for years to come.

The astronomy lab at the University of Maine consists of discrete weekly lessons in which students work in small groups. Individual pretests and post-tests accompany each lesson. The lesson studied here covers the topic of time, including sidereal time, Apparent Solar Time, and time zones. The pretest consists of four multiple-choice questions, which are also administered after instruction as a post-test. In the fall 2004 semester, the pretest was rewritten to focus on some major conceptual components of the lab, while the lesson materials were not modified from previous years. Examination of class performance (n = 96) revealed no significant improvements in score from pre- to post-lesson. In the spring 2005 semester, the lesson was altered to incorporate the Starry Night software for simulating the sky instead of the celestial sphere models previously used. The goal of the change was to give students a more interactive environment for completing the laboratory exercise, which was otherwise altered as little as possible. Data from the spring semester show some gains on the pre/post-test questions covering sidereal time and Daylight Savings Time. Results to date have informed planned modifications to the lesson. A. L. T. was supported during this research by the University of Maine through a Provost Fellowship.

Science teachers are being called on to incorporate engineering practices into their classrooms. This study explores whether the Engineering-Infused Lesson Rubric, a new rubric designed to target best practices in engineering education, could be used to evaluate the extent to which engineering is infused into online science lessons. Eighty lessons were selected at random from three online repositories, and coded with the rubric. Overall results documented the strengths of existing lessons, as well as many components that teachers might strengthen. In addition, a subset of characteristics was found to distinguish lessons with the highest level of engineering infusion. Findings are discussed in relation to the potential of the rubric to help teachers use research evidence-informed practice generally, and in relation to the new content demands of the U.S. Next Generation Science Standards, in particular.

Lessons learned on the Ground Test Accelerator control system

International Nuclear Information System (INIS)

Kozubal, A.J.; Weiss, R.E.

1994-01-01

When we initiated the control system design for the Ground Test Accelerator (GTA), we envisioned a system that would be flexible enough to handle the changing requirements of an experimental project. This control system would use a developers' toolkit to reduce the cost and time to develop applications for GTA, and through the use of open standards, the system would accommodate unforeseen requirements as they arose. Furthermore, we would attempt to demonstrate on GTA a level of automation far beyond that achieved by existing accelerator control systems. How well did we achieve these goals? What were the stumbling blocks to deploying the control system, and what assumptions did we make about requirements that turned out to be incorrect? In this paper we look at the process of developing a control system that evolved into what is now the ''Experimental Physics and Industrial Control System'' (EPICS). Also, we assess the impact of this system on the GTA project, as well as the impact of GTA on EPICS. The lessons learned on GTA will be valuable for future projects

This report summarizes the Nuclear Regulatory Commission staff's observations and lessons learned from the five License Renewal Demonstration Program (LRDP) site visits performed by the staff from March 25, 1996, through August 16, 1996. The LRDP was a Nuclear Energy Institute (NEI) program intended to assess the effectiveness of the guidance provided by NEI 95-10, Revision 0, open-quotes Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule,close quotes to implement the requirements of Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54), open-quotes Requirements for Renewal of Operating Licenses for Nuclear Power Plants.close quotes In general, NEI 95-10 appeared to contain the basic guidance needed for scoping, screening, identifying aging effects, developing aging management programs, and performing time-limited aging analyses. However, inconsistent implementation of this guidance in some areas was an indication that clarification of existing guidance and/or the inclusion-of some new guidance may be needed for applicants to develop a license renewal program that is consistent with the intent of the rule

Deregulation and natural gas trade relationships: lessons from the Alberta-California experience

International Nuclear Information System (INIS)

Wilson, Patrick Impero

1997-01-01

In 1978 the US government moved to deregulate the American natural gas industry. The market changes that resulted from this initial step took time to ripple their way out to regional and subnational gas trading relationships. This ripple effect required subnational governments (state and provincial regulators) to rethink their gas regulatory policies. This article examines the restructuring of the Alberta-California gas trade. It explores how changes in US policy forced California and Alberta regulators to recast their policies. It concludes with several lessons that can be drawn from this case about the complex challenge of restructuring international gas trading relationships. (author)

Integration of physical active academic lessons in the school curriculum may be an innovative way to improve academic outcomes. This study examined the effect of physically active academic lessons (Fit en Vaardig op school) on academic engagement of socially disadvantaged children and children without this disadvantage. In addition, the relationship between lesson time spent in moderate to vigorous physical activity and academic engagement was examined. From four elementary schools, 86 children who participated in the 22-weeks intervention were recruited (23 socially disadvantaged children). Academic engagement was determined by observing time-on-task during three classroom observation moments (start, midway and end observation). Every moment consisted of lesson observations after intervention lessons (post-intervention) and after regular classroom lessons (post-control). Differences in time-on-task between socially disadvantaged children and children without this disadvantage were analyzed using independent samples t-test. Differences between post-intervention and post-control observations were analyzed using multilevel analysis. Heart rate monitors measured the lesson time spent in moderate to vigorous physical activity. The relationship between percentage of moderate to vigorous physical activity during the intervention lessons and time-on-task was analyzed by calculation of partial correlations. Time-on-task of socially disadvantaged children was lower than that of children without this disadvantage, differences were significant at the start post-control (t(65) = 2.39, p < 0.05) and post-intervention (t(71) = 2.75, p < 0.05) observation and at the midway post-control (t(68) = 2.45, p < 0.05) observation. Multilevel analysis showed that the time-on-task of all children was significantly higher during post-intervention in comparison with post-control lessons (ES = 0.41). No significant difference was found at the start observation, but

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 role of failure/problems in engineering: A commentary of failures experienced - lessons learned

Ryan, R. S.

1992-03-01

The written version of a series of seminars given to several aerospace companies and three NASA centers are presented. The results are lessons learned through a study of the problems experienced in 35 years of engineering. The basic conclusion is that the primary cause of problems has not been mission technologies, as important as technology is, but the neglect of basic principles. Undergirding this is the lack of a systems focus from determining requirements through design, verification, and operations phases. Many of the concepts discussed are fundamental to total quality management (TQM) and can be used to augment this product enhanced philosophy. Fourteen principles are addressed with problems experienced and are used as examples. Included is a discussion of the implication of constraints, poorly defined requirements, and schedules. Design guidelines, lessons learned, and future tasks are listed. Two additional sections are included that deal with personal lessons learned and thoughts on future thrusts (TQM).

Everyday robotic action: Lessons from human action control

Directory of Open Access Journals (Sweden)

Roy eDe Kleijn

2014-03-01

Full Text Available Robots are increasingly capable of performing everyday human activities such as cooking, cleaning, and doing the laundry. This requires the real-time planning and execution of complex, temporally-extended sequential actions under high degrees of uncertainty, which provides many challenges to traditional approaches to robot action control. We argue that important lessons in this respect can be learned from research on human action control. We provide a brief overview of available psychological insights into this issue and focus on four principles that we think could be particularly beneficial for robot control: the integration of symbolic and subsymbolic planning of action sequences, the integration of feedforward and feedback control, the clustering of complex actions into subcomponents, and the contextualization of action-control structures through goal representations.

Phagocytosis: history's lessons.

Science.gov (United States)

Garg, Manish; Chandawarkar, Rajiv Y

2013-01-01

The assimilation of lessons from the past is an essential component of education for scientists of tomorrow. These lessons are not easy to find. History books on science are few and usually highly dramatized and biographies of scientists tend to exaggerate the pomp of scientific discovery. Both underplay the hard and laborious work that is integral to any scientific pursuit. Here we illustrate one such example. A century ago, the Nobel Prize in Medicine was awarded to two scientists: Ilya Metchnikoff, a Russian zoologist, for the discovery ofphagocytosis-a cell-mediated ingestion ofmicrobes; and Paul Ehrlich, a distinguished physician-scientist, for discovering a highly antigen-specific serum-derived antibody-based immune defense. These two diametrically opposing views of the host-pathogen interaction set the stage for a strife that led to seminal advancements in immunology. Mirrored in this journey are important lessons for scientists today--ubiquitously as applicable to modern scientific life as they were a century ago. This commentaryhighlights these lessons--a fitting centenary to a well-deserved recognition.

The following five Safety Requirements publications were amended: Governmental, Legal and Regulatory Framework for Safety (GSR Part 1, 2010), Site Evaluation for Nuclear Installations (NS-R-3, 2003), Safety of Nuclear Power Plants: Design (SSR-2/1, 2012), Safety of Nuclear Power Plants: Commissioning and Operation (SSR-2/2, 2011), and Safety Assessment for Facilities and Activities (GSR Part 4, 2009). Figure 1 shows IAEA Safety Standards Categories Major amendments of five Safety Requirements publications were introduced and analyzed in this study. The five IAEA safety requirements publications which are GSR Part 1 and 4, NS-R-3 and SSR-2/1 and 2, were amended to reflect the lesson learned from the Fukushima accident and other operating experiences. Specially, 36 provisions were modified and the new 29 provision with 1 requirement (No. 67: Emergency response facilities on the site) of the SSR-2/1 were established. Since the Fukushima accident happened, a new word, design extension conditions (DECs) which cover substantially the beyond design basis accidents (BDBA), including severe accident conditions, was created and more elaborated by the world nuclear experts. Design extension conditions could include conditions in events without significant fuel degradation and conditions with core melting. Figure 2 shows the range of the DECs. The amendment of the five IAEA safety requirements publications are focused at the prevention of initiating events, which would lead to the DECs, and mitigation of the consequences of DECs by the enhanced defense in depth principle. The following examples of the IAEA requirements to prevent the initiating events are: margins for withstanding external events; margins for avoiding cliff edge effects; safety assessment for multiple facilities or activities at a single site; safety assessment in cases where resources at a facility are shared; consideration of the potential occurrence of events in combination; establishing levels of hazard

On January, 2011, a devastating tropical storm hit the mountain area of Rio de Janeiro State in Brazil, resulting in flooding and mudslides and leaving 30,000 individuals displaced. This article explores key lessons learned from this major mass casualty event, highlighting prehospital and hospital organization for receiving multiple victims in a short period of time, which may be applicable in similar future events worldwide. A retrospective review of local hospital medical/fire department records and data from the Health and Security Department of the State were analyzed. Medical examiner archives were analyzed to determine the causes of death. The most common injuries were to the extremities, the majority requiring only wound cleaning, debridement, and suture. Orthopedic surgeries were the most common operative procedures. In the first 3 days, 191 victims underwent triage at the hospital with 50 requiring admission to the hospital. Two hundred fifty patients were triaged at the hospital by the end of the fifth day. The mortis cause for the majority of deaths was asphyxia, either by drowning or mud burial. Natural disasters are able to generate a large number of victims and overwhelm the main channels of relief available. Main lessons learned are as follows: 1) prevention and training are key points, 2) key measures by the authorities should be taken as early as possible, and 3) the centralization of the deceased in one location demonstrated greater effectiveness identifying victims and releasing the bodies back to families.

Several remediation projects have been developed to date, and experience with these projects has been accumulated. Lessons learned span from non-technical to technical aspects, and need to be shared with those who are beginning or are facing the challenge to implement environmental remediation works. This publication reviews some of these lessons. The key role of policy and strategies at the national level in framing the conditions in which remediation projects are to be developed and decisions made is emphasized. Following policy matters, this publication pays attention to the importance of social aspects and the requirement for fairness in decisions to be made, something that can only be achieved with the involvement of a broad range of interested parties in the decision making process. The publication also reviews the funding of remediation projects, planning, contracting, cost estimates and procurement, and issues related to long term stewardship. Lessons learned regarding technical aspects of remediation projects are reviewed. Techniques such as the application of cover systems and soil remediation (electrokinetics, phytoremediation, soil flushing, and solidification and stabilization techniques) are analysed with respect to performance and cost. After discussing soil remediation, the publication covers issues associated with water treatment, where techniques such as ‘pump and treat’ and the application of permeable barriers are reviewed. Subsequently, there is a section dedicated to reviewing briefly the lessons learned in the remediation of uranium mining and processing sites. Many of these sites throughout the world have become orphaned, and are waiting for remediation. The publication notes that little progress has been made in the management of some of these sites, particularly in the understanding of associated environmental and health risks, and the ability to apply prediction to future environmental and health standards.

Medical faculty members' attitude on lesson planning Semnan University of Medical Sciences

Directory of Open Access Journals (Sweden)

Masomeh Saberian

2003-01-01

Full Text Available Background: Lesson planning has a distinct role in enhancing education quality, as well as maintaining the friendly and dynamic atmosphere of the academic environment and increasing student's initiatives for achieving better educational attainments. Lesson planning is a process for defining the goals, understanding the needs, and specifying available tools and possible limitations. Lesson planning is a written description of this process, which shows the materials, the route, the time, and the place of instructions, as well as a method for evaluating students. Purpose: to identify the attitudes of Semnan University of Medical Sciences (SUMS on lesson planning. Methods: Fifty-three faculty members of the SUMS participated in this study. A questionnaire was used, which contained 8 demographic questions, and 24 r questions for identification the faculty members' attitude. Questionnaires were distributed among the faculty members in sealed envelopes, without denoting their names. The questionnaires were gathered after being completed. Results were analyzed by calculating the mean, standard deviation, absolute and relative frequencies, and using Chi-square and Fischer exact test at the level of 5%. Results: II was shown that 88% of faculty members favoured lesson planning before the beginning of the semester. But they found lesson planning a difficult task, because of their heavy workload. Of the faculty members, 60.4% organized their teaching classes according to a designed lesson plan, and believed that it did affect the quality of their teaching, but 49.1% disagreed with distributing the designed lesson plan among the students. Discussion: Although professor favoured lesson planning and find it necessary to work according to such a plan, workload and lack of knowledge are defined as two main obstacles in doing so. It is believed that by decreasing the professor's workload and provision of lesson planning workshops, these problems could be solved

In November 2012 Colorado voters approved legalized recreational marijuana. On January 1, 2014 Colorado became the first state to allow legal sales of non-medical marijuana for adults over the age of 21. Since that time, the state has been monitoring potential impacts on population health. In this paper we present lessons learned in the first three years following legal sales of recreational marijuana. These lessons pertain to health behaviors and health outcomes, as well as to health policy issues. Our intent is to share these lessons with other states as they face the prospect of recreational marijuana legalization. Copyright © 2017 Elsevier Inc. All rights reserved.

Crom, T.D.; Naugle, C.L. [Duke Engineering & Services, Inc., Charlotte, NC (United States); Turk, R.S. [ABB Combustion Engineering Nuclear Power, Windsor, CT (United States)

1995-03-01

Many lessons have been learned from the current generation of nuclear plants in the area of radiation protection. The following paper will outline how the lessons learned have been incorporated into the design and operational philosophy of the System 80+{trademark} Standard Design currently under development by ABB Combustion Engineering (ABB-CE) with support from Duke Engineering and Services, Inc. and Stone and Webster Engineering Corporation in the Balance-of-Plant design. The System 80+{trademark} Standard Design is a complete nuclear power plant for national and international markets, designed in direct response to utility needs for the 1990`s, and scheduled for Nuclear Regulatory Commission (NRC) Design Certification under the new standardization rule (10 CFR Part 52). System 80+{trademark} is a natural extension of System 80{sup R} technology, an evolutionary change based on proven Nuclear Steam Supply System (NSSS) in operation at Palo Verde in Arizona and under construction at Yonggwang in the Republic of Korea. The System 80+{trademark} Containment and much of the Balance of Plant design is based upon Duke Power Company`s Cherokee Plant, which was partially constructed in the late 1970`s, but, was later canceled (due to rapid declined in electrical load growth). The System 80+{trademark} Standard Design meets the requirements given in the Electric Power Research Institute (EPRI) Advanced Light Water Reactor (ALWR) Requirements Document. One of these requirements is to limit the occupational exposure to 100 person-rem/yr. This paper illustrates how this goal can be achieved through the incorporation of lessons learned, innovative design, and the implementation of a common sense approach to operation and maintenances practices.

Qualitative Data Collection and Interpretation: A Turkish Social Studies Lesson

Directory of Open Access Journals (Sweden)

Tilman Grammes

2016-05-01

Full Text Available The classroom with its teaching-learning dynamics creates a kind of “embryonic society” in which the micro-policies of collective social knowledge construction and meaning can be re-constructed; therefore, it can be considered as a kind of “mirror” of political culture. Thus, comparative lesson research, which requires indepth classroom observation, has been getting much attention among educational community. On the other hand, there have not been done many studies that represent social studies and civics in particular, in this research tradition. Naturally, this research tradition is based on qualitative research paradigm. Likewise, qualitative research tradition has been getting increasing attention among educational community. Thus, the first purpose of this article is to explain all documentation and pre-interpretation process of this lesson so that it can provide an example for qualitative researchers. The second purpose of this article is to provide an example lesson of political education from Turkey so that educators worldwide can compare one example of social studies education practice in Turkey and with their countries.

Effect of long construction times on utility financial requirements

International Nuclear Information System (INIS)

Francis, J.M.

1981-01-01

It is well-known that long construction times significantly increase the cost of an individual nuclear plant. Long construction times, however, are not confined to either a single plant or a single utility. Rather, they apparently occur in almost all nuclear plants currently under construction. The total financial requirement to complete the 82 nuclear plants currently under construction was assessed. The analysis was performed assuming a construction time of ten years in one case, and six years in another. It was found that decreasing the construction time from ten to six years will reduce the financial requirements of the utility industry by $89 billion

Full Text Available The article describes the use of cinematic materials, especially materials from feature films as one of the best means to assimilate the information on the lessons with suggestopedic educational technology. Scientific research of this method including on geography  essons, have been analyzed. Modern pupils study, learn and grow under the influence of communication technologies, so they require a rapid response and adaptation to modern conditions, as well as other interests, a special motivation in training. Feature films, like nothing else, captivates the modern youth, so there is an opportunity to use the screen art for educational purposes and effect of the suggestopedic influence allows pupils to perceive a large amount of information. The use of cinematic materials with suggestopedic educational technology on geography lessons belongs to audiovisual learning tools, giving the opportunity to acquire different modern motivating knowledge. After analyzing suggestive teaching methods, the results of these methods application have been presented, the essence of cinematic materials use as audiovisual learning tools, especially materials from feature films, on suggestopedic lessons and feasibility of their use in the educational process have been described. The authors propose to focus on artistic learning tools or means of art, as a special type of vacated (released stimulating didactical art, that reveals the spare capacity in education and improves memorization and understanding of the studied material when using cinematic materials on geography lessons with suggestopedic educational technology. Methodical recommendations for the suggestopedic lesson using cinematic materials for the topic «Major relief forms of dry land of the Earth.

Lessons Learned in International Safeguards - Implementation of Safeguards at the Rokkasho Reprocessing Plant

International Nuclear Information System (INIS)

Ehinger, Michael H.; Johnson, Shirley

2010-01-01

The focus of this report is lessons learned at the Rokkasho Reprocessing Plant (RRP). However, the subject of lessons learned for application of international safeguards at reprocessing plants includes a cumulative history of inspections starting at the West Valley (New York, U.S.A.) reprocessing plant in 1969 and proceeding through all of the efforts over the years. The RRP is the latest and most challenging application the International Atomic Energy Agency has faced. In many ways the challenges have remained the same, timely inspection and evaluation with limited inspector resources, with the continuing realization that planning and preparations can never start early enough in the life cycle of a facility. Lessons learned over the years have involved the challenges of using ongoing advances in technology and dealing with facilities with increased throughput and continuous operation. This report will begin with a review of historical developments and lessons learned. This will provide a basis for a discussion of the experiences and lessons learned from the implementation of international safeguards at RRP.

Thacker, M. S.; Freshour, P.; McDonald, W.

2002-01-01

Valuable experience in environmental remediation was gained at Sandia National Laboratories/New Mexico (Sandia) by concurrently conducting Voluntary Corrective Actions (VCAs) at three Solid Waste Management Units (SWMUs). Sandia combined the planning, implementation, and reporting phases of three VCAs with the goal of realizing significant savings in both cost and schedule. The lessons learned through this process have been successfully implemented within the Sandia Environmental Restoration (ER) Project and could be utilized at other locations with multiple ER sites. All lessons learned resulted from successful teaming with the New Mexico Environment Department (NMED) Hazardous Waste Bureau (HWB), Sandia management, a Sandia risk assessment team, and Sandia waste management personnel. Specific lessons learned included the following: (1) potential efficiencies can be exploited by reprioritization and rescheduling of activities; (2) cost and schedule reductions can be realized by combining similar work at contiguous sites into a single effort; (3) working with regulators to develop preliminary remediation goals (PRGs) and gain regulatory acceptance for VCA planning prior to project initiation results in significant time savings throughout the remediation and permit modification processes; (4) effective and thoughtful contingency planning removes uncertainties and defrays costs so that projects can be completed without interruption; (5) timely collection of waste characterization samples allows efficient disposal of waste streams, and (6) concurrent reporting of VCA activities results in significant savings in time for the authors and reviewers

Expensive, Frustrating and Perilous: Lessons Learned from Charting New Waters in Liberalized Markets

Energy Technology Data Exchange (ETDEWEB)

Hastings, Matthew T.

2007-07-01

By 2030 utilities will have spent billions in investment to maintain, upgrade and expand their infrastructure. To attract investment utilities operating in liberalized markets will increasingly be required to report, perform and operate in ways that are very different from the current. Market liberalization, or deregulation, of the electricity sector has been an ongoing process in the United States for almost two decades. Every single element of utility management, operations and finance has changed dramatically and irrevocably. Building and maintaining investor confidence in the utility sector will be an ongoing challenge for every individual player. The US experience has demonstrated that open markets are much less tolerant of management missteps and failures to reach stated goals and objectives. The US experience has resulted in a range of ''lessons learned'' that will be of interest to market players as they develop and implement strategies to build and maintain competitive position. This paper discusses elements of the US experience, and the pursuant opportunities for international players to benefit from, the expensive and often times painful ''lessons learned''. (auth)

2018-01-01

Abstract Objective To respond to the World Health Assembly call for dissemination of lessons learnt from countries that have begun implementing the International Health Regulations, 2005 revision; IHR (2005). Methods In November 2015, we conducted a systematic search of the following online databases and sources: PubMed®, Embase®, Global Health, Scopus, World Health Organization (WHO) Global Index Medicus, WHO Bulletin on IHR Implementation and the International Society for Disease Surveillance. We included identified studies and reports summarizing national experience in implementing any of the IHR (2005) core capacities or their components. We excluded studies that were theoretical or referred to IHR (1969). Qualitative systematic review methodology, including meta-ethnography, was used for qualitative synthesis. Findings We analysed 51 articles from 77 countries representing all WHO Regions. The meta-syntheses identified a total of 44 lessons learnt across the eight core capacities of IHR (2005). Major themes included the need to mobilize and sustain political commitment; to adapt global requirements based on local sociocultural, epidemiological, health system and economic contexts; and to conduct baseline and follow-up assessments to monitor the status of IHR (2005) implementation. Conclusion Although experiences of IHR (2005) implementation covered a wide global range, more documentation from Africa and Eastern Europe is needed. We did not find specific areas of weakness in monitoring IHR (2005); sustained monitoring of all core capacities is required to ensure effective systems. These lessons learnt could be adapted by countries in the process of meeting IHR (2005) requirements. PMID:29403114

The Value of Identifying and Recovering Lost GN&C Lessons Learned: Aeronautical, Spacecraft, and Launch Vehicle Examples

Science.gov (United States)

Dennehy, Cornelius J.; Labbe, Steve; Lebsock, Kenneth L.

2010-01-01

Within the broad aerospace community the importance of identifying, documenting and widely sharing lessons learned during system development, flight test, operational or research programs/projects is broadly acknowledged. Documenting and sharing lessons learned helps managers and engineers to minimize project risk and improve performance of their systems. Often significant lessons learned on a project fail to get captured even though they are well known 'tribal knowledge' amongst the project team members. The physical act of actually writing down and documenting these lessons learned for the next generation of NASA GN&C engineers fails to happen on some projects for various reasons. In this paper we will first review the importance of capturing lessons learned and then will discuss reasons why some lessons are not documented. A simple proven approach called 'Pause and Learn' will be highlighted as a proven low-impact method of organizational learning that could foster the timely capture of critical lessons learned. Lastly some examples of 'lost' GN&C lessons learned from the aeronautics, spacecraft and launch vehicle domains are briefly highlighted. In the context of this paper 'lost' refers to lessons that have not achieved broad visibility within the NASA-wide GN&C CoP because they are either undocumented, masked or poorly documented in the NASA Lessons Learned Information System (LLIS).

Lewenson, Sandra B; Welch, Cathryne A; Hassmiller, Susan B

2015-10-01

While directing the Future of Nursing: Campaign for Action, Susan B. Hassmiller, the Robert Wood Johnson Foundation's senior adviser for nursing, realized the value that nursing history could bring to the campaign. She decided to interview her mother, Jacqueline J. Wouwenberg, a 1947 graduate of the Bellevue Hospital School of Nursing, in order to better understand and contextualize changes that had occurred in the nursing profession during the 20th century. In collaboration with nurse historians Cathryne A. Welch and Sandra B. Lewenson, Hassmiller participated in interviewing her mother and was also interviewed herself. The stories that emerged revealed a great deal: each woman had found that nursing had given them countless opportunities that reflected the time periods in which they lived. Wouwenberg's experiences, transmitted to Hassmiller through words and actions, also served as important lessons for her daughter. This article shares five lessons: be independent and courageous, know that nursing has no bounds, follow your passion, honor diversity, and give back. It also asks readers to reflect on the relevance of nurses' work from one generation to the next..

BLENDED LEARNING: STUDENT PERCEPTION OF FACE-TO-FACE AND ONLINE EFL LESSONS

Directory of Open Access Journals (Sweden)

Brenda M. Wright

2017-05-01

Full Text Available With the ever-increasing development of technology, online teaching is more readily accepted as a viable component in teaching and learning, and blended learning, the combining of online and face-to-face learning, is becoming commonplace in many higher education institutions. Blended learning is, particularly in developing countries, in its early stages and not without its challenges. Asynchronous online lessons are currently still more prevalent in many areas of South-East Asia, perhaps due to potential difficulty in obtaining strong Internet connections, which may deter educators from synchronous options. Technological media have the potential to broaden the scope of resources available in teaching and to enhance the language learning experience. Although research to date shows some focus on blended learning, literature on distance online teaching seems more prevalent. This study exposed 112 Malaysian undergraduate EFL students' responses to an online lesson as part of an English grammar course, and investigates common student perceptions of the online lesson as compared with face-to-face lessons. Questionnaires using qualitative (Likert scale questions and quantitative (open-ended questions approaches provided data for content analysis to determine common student perceptions, with particular reference to motivation and interest. In general, more students associated in-class lessons with higher motivation and more interest, due to better understanding, valued classroom interaction with the lecturer and peers, and input from the lecturer. Students preferring the online lesson cited speed and convenience of study and flexibility of time and place of study as reasons for their choice. Skilful implementation of online lessons can enhance a language course but should not undermine the value of face-to-face instruction with EFL teachers.

Reflection after teaching a lesson: Experiences of secondary school science teachers

Science.gov (United States)

Halstead, Melissa A.

Secondary science teachers spend most of their time planning, collaborating, and teaching, but spend little time reflecting after teaching a single lesson. The theoretical framework of the adult learning theory and the transformative learning theory was the basis of this study. This qualitative research study was conducted to understand the reflective experiences of secondary science educators after teaching a single or several lessons. The collection of data consisted of interviews from a group of purposefully selected secondary science teachers who met the criteria set forth by the researcher. Through a qualitative analysis of interviews and field notes, the researcher determined that the secondary science teachers in this study shared similar as well as different experiences regarding collaborative and individual reflection after teaching a single or several lessons. The findings from this study also suggested that secondary science educators prefer to collaboratively reflect and then reflect alone to allow for further thought. Additionally, a supportive school culture increases the secondary science teacher’s desire to engage in collaborative as well as individual reflection. The information from this study could be used to close the gaps that exist in the teacher professional development programs.

A real-time internal dose assessment exercise has been conducted in which participants were required to make decisions about sampling requirements, seek relevant information about the 'incident' and make various interim dose assessments. At the end of the exercise, each participant was requested to make a formal assessment, providing statements of the methods, models and assumptions used in that assessment. In this paper we describe how the hypothetical assessment case was set up and the exercise was conducted, the responses of the participants and the assessments of dose that they made. Finally we discuss the lessons learnt from the exercise and suggest how the exercise may be adapted to a wider range of participants. (authors)

Physically active academic lessons in elementary children.

Science.gov (United States)

Bartholomew, John B; Jowers, Esbelle M

2011-06-01

Although schools are an ideal location to conduct interventions that target children, the emphasis on standardized testing makes it difficult to implement interventions that do not directly support academic instruction. In response, physically active academic lessons have been developed as a strategy to increase physical activity while also addressing core educational goals. Texas I-CAN! is one incarnation of this approach. We will review the on-going research on the impact of these active lessons on: teacher implementation, child step count, child attention control, and academic performance. The collected studies support the impact of physically active academic lessons on each area of interest. If these data can be replicated, it suggests that teachers might find these lessons of benefit to their primary role as educators, which should ease dissemination of these and other physically active lessons in elementary schools.

Teaching Norwegian to Beginners: Six Principles to Guide Lesson Planning

Directory of Open Access Journals (Sweden)

Anna Krulatz

2014-01-01

Full Text Available Teaching a foreign language is no simple task. There are several factors to consider, from curriculum design, to material selection and lesson implementation, to assessment. The challenge, however, is even greater, if you are teaching a less commonly taught language such as Norwegian – a language spoken by fewer than six million native speakers, used almost exclusively in one country, and with a limited number of available pedagogical materials. Under such circumstances, the task of preparing high quality communicative lessons is immense, even for an experienced language instructor. The goal of this article is to present how a successful language lesson can be developed even if one is using a textbook that does not foster communicative competence. As an example, I am using a unit from a Norwegian textbook for beginners: På vei, often used in Norwegian as a second language course for adults in Norway. The lesson focuses on routines and times of the day, and it concludes with the students comparing and contrasting their daily routines with a partner. Prior to this lesson, students have learned to provide basic information about themselves (where they come from, what languages they speak, what they do for work, expressions for greetings and goodbyes, basic verbs relating to daily activities such as ‘snakker’ (to speak, ‘kjører’ (to drive, ‘kjøpper’ (to buy, ‘jobber’ (to work, ‘leser’ (to read, ‘scriver’ (to write, ordinal numerals, meals, some food items, some basic prepositions and locations, words for family members, and subject and object pronouns for all persons. If you were to closely follow the textbook in teaching this unit, you would begin by teaching the students how to tell time, then briefly go over some verbs to express daily routines, listen to and read a text titled ‘Jeg står opp klokka seks,’ a narrative about Monica’s day (Monica is one of the characters in the book, and finally ask the students

Overview of lessons learnt

International Nuclear Information System (INIS)

Pescatore, C.; Federline, M.; Duncan, A.

2004-01-01

During the Tarragona International Seminar the participating high-level specialists had very open and fruitful discussion concerning strategic decommissioning issues. The lessons learnt and possible solutions for future work issues can be found below. Although there appears to be a trend towards early dismantling, there seemed to be general agreement that technical solutions support a wide variety of safe decommissioning approaches. Thus, in terms of decommissioning strategy, it appears that no one size fits all. A flexible regulatory approach is needed in order to recognize the changing operational risks and physical conditions of facilities with time, and to optimise their dismantling. The NEA has released a comprehensive study on decommissioning strategies and costs that indicates world-wide progress. According to this report, over 50% of countries with nuclear facilities have a framework of decommissioning requirements and 60% have defined radioactive waste clearance levels. Up to about 70% of the costs of D and D are attributable to dismantling and waste management. The provisions for safety of the D and D process are closely linked to the availability of the necessary funds as and when required. A number of common factors were defined for successful implementation of decommissioning strategies: i.e. safety, technical feasibility of decommissioning options, risk-informed progression of D and D activities as project proceeds, maintenance of competency and corporate memory throughout project, waste management and disposal capability, financing that suits the scope of the project, a well-defined risk-informed and performance-based regulatory process, and establishment of effective communication with local and regional governments and key stakeholders, particularly personnel, at the earliest opportunity before decommissioning.

Lessons Learned in Pilot Testing Specialty Consultations to Benefit Individuals with Lower Limb Loss

Directory of Open Access Journals (Sweden)

Christine Elnitsky

2012-12-01

Full Text Available Telerehabilitation technologies enable the delivery of rehabilitation services from providers to people with disabilities as well as specialty care consultations. This article discusses the barriers experienced when planning and pilot testing a telerehabilitation multi-site specialty consultation for specialists in their medical centers, and the lessons learned. The barriers included integration and participation, coordination across organizational units, and privacy and information security. Lessons learned included the need for collaboration across multiple departments, telerehabilitation equipment back-ups, and anonymous and private communication protocols. Despite delays resulting from coordination at multiple levels of a national organization, we developed a program plan and successfully implemented a pilot test of the southeast region program.  Specialty consultation using telerehabilitation delivery methods requires identifying provider preferences for technological features. Lessons learned could inform development of outpatient telerehabilitation for patients with amputations and studies of patients and providers involved in telerehabilitation.

CEA's waste management policy and strategy. Lessons learned - 59201

International Nuclear Information System (INIS)

Dall'ava, Didier

2012-01-01

Document available in abstract form only. Full text of publication follows: Radioactive wastes are generated during operation as well as during the decontamination and dismantling of CEA's nuclear facility/installation. The safe and responsible management of radioactive wastes at all stages is an essential requirement of the regulatory system. The management covers the whole sequence of operations starting with the generation of waste and ending with its disposal. The disposal here means discarding of waste with no intention for retrieval. It is important to note here that the safety principles and practices that are applicable during the operational phase are also applicable during the decommissioning phase. As the radioactive waste arising is an inevitable outcome of decommissioning work, all the regulatory requirements associated with decommissioning remain in force in waste management. This presentation deals initially with the regulatory standards related to the management of wastes. As the management of radioactive wastes inevitably includes treatment and conditioning of wastes, following treatment and conditioning of wastes, storage, transportation and eventual disposal are the logical outcome of the radioactive wastes, processes are at any time improved based on the feedback experience and the lessons learned.

Students’ motivation in a disc golf-lesson and a soccer-lesson: An experimental study in the Physical Education setting

Directory of Open Access Journals (Sweden)

Kristian Vernegaard

2017-09-01

Full Text Available One of the purposes of physical education (PE in both Norway and Denmark is that PE should inspire to a lifelong active lifestyle. Based on the self-determination theory, the aim of the present study was to compare students’ intrinsic motivation, extrinsic motivation, and perceived competence in a lifestyle sport inspired PE-lesson (disc golf to a traditional PE-lesson (soccer and general PE. In addition, we aimed to investigate whether differences in motivation and perceived competence were conditional of the students’ relative attitude toward PE. The result of the study revealed that perceived competence was higher in the disc golf-lesson compared to the soccer-lesson and general PE. No overall differences in intrinsic motivation were found. However, when investigating differences in intrinsic motivation according to the students’ relative attitude toward PE, the results indicated that the students with a negative attitude toward PE was significantly more intrinsically motivated in disc golf-lesson compared to soccer-lesson and general PE. The findings may be seen as further recommendations to physical educators to vary the activity choices in physical education classes.

Implementing Indigenous community control in health care: lessons from Canada.

Science.gov (United States)

Lavoie, Josée G; Dwyer, Judith

2016-09-01

Objective Over past decades, Australian and Canadian Indigenous primary healthcare policies have focused on supporting community controlled Indigenous health organisations. After more than 20 years of sustained effort, over 89% of eligible communities in Canada are currently engaged in the planning, management and provision of community controlled health services. In Australia, policy commitment to community control has also been in place for more than 25 years, but implementation has been complicated by unrealistic timelines, underdeveloped change management processes, inflexible funding agreements and distrust. This paper discusses the lessons from the Canadian experience to inform the continuing efforts to achieve the implementation of community control in Australia. Methods We reviewed Canadian policy and evaluation grey literature documents, and assessed lessons and recommendations for relevance to the Australian context. Results Our analysis yielded three broad lessons. First, implementing community control takes time. It took Canada 20 years to achieve 89% implementation. To succeed, Australia will need to make a firm long term commitment to this objective. Second, implementing community control is complex. Communities require adequate resources to support change management. And third, accountability frameworks must be tailored to the Indigenous primary health care context to be meaningful. Conclusions We conclude that although the Canadian experience is based on a different context, the processes and tools created to implement community control in Canada can help inform the Australian context. What is known about the topic? Although Australia has promoted Indigenous control over primary healthcare (PHC) services, implementation remains incomplete. Enduring barriers to the transfer of PHC services to community control have not been addressed in the largely sporadic attention to this challenge to date, despite significant recent efforts in some jurisdictions

Lessons of the Great Patriotic War and World War II for Contemporary Russia

Full Text Available After the Second World War 70 years have passed. Essentially already gone a generation of people for whom it was not a story, and the nationwide disaster and personal experience. And let time more and more we move away from the victory of 1945, the value and results of the war are enormous for the future of the modern world. Memory of the Great Victory presents to all of us now living, special requirements, the main of which consists in the fact that based on the analysis draw the necessary lessons from the past, draw the right conclusions for the safety of modern Russia. Over the years, the world has changed considerably. On the stage of world politics, a host of new independent states. There are new centers of economic development, and hence the new poles of power. Meanwhile, the events of recent months show that the main results of the Victory have not lost their importance today. This is best spoken of their incessant attempts to challenge by distorting the main points of the war and its lessons. And, obviously, it is no accident the day before and during the celebration of 70th anniversary of Victory wishing her to steal the peoples of Russia have been particularly active, as they claim - stiff and awkward. For domestic historiography it is not something unexpected. On the socio-political, military and economic results of the Second World War written many works, but probably in the light of the development of military-political processes in the world of individual instructive lesson it is important not to forget.

Designing Conservation Corridors in Production Landscapes: Assessment Methods, Implementation Issues, and Lessons Learned

Directory of Open Access Journals (Sweden)

Amanda T. Lombard

2010-09-01

Full Text Available Designing broad-scale conservation corridors has become increasingly common as a way of conducting an assessment for achieving targets for the representation and persistence of nature. However, since many of these corridors must traverse agricultural and other production landscapes, planning and implementation are not trivial tasks. Most approaches to conservation assessments in the dynamic world of production landscapes are data-intensive and analytically complex. However, in the real world, donor and other external requirements impose time and budget constraints, and dictate strong stakeholder involvement in the entire planning process. In order to accommodate this, assessments must be rapid, cheap, and the approach and products must be comprehensible and acceptable to stakeholders. Here we describe such an assessment aimed at identifying and implementing a network of conservation corridors in the Gouritz Initiative project domain of South Africa's Cape Floristic Region hotspot. We used empirical data and expert knowledge to identify a corridor network hypothesized to sustain key ecological and evolutionary processes. We also consulted experts to provide a spatially explicit assessment of the opportunity costs of conservation associated with agriculture, the predominant land use in the region. We used these products to identify categories of land requiring different actions and instruments to achieve conservation goals, thereby moving from the "where" to the "how" of conservation. This information was then fed into the collaborative strategy development process for the Gouritz Initiative. Our discussion emphasizes the lessons that we learnt from undertaking this assessment, particularly lessons regarding the implementation of the planning products. We conclude that at the outset of any planning project, a consensus on the vision must be achieved, a detailed social assessment of appropriate institutions must be undertaken, and a learning

This article based of collaborative classroom action research with science teachers group or MGMP at Solok West Sumatera; based on their willingness to implementation of lesson study by this group. The study started by discussing some problems according to the implementation of the lesson study, establishing the teaching materials, developing learning tools, defining the model teachers, conducting classroom activities, and reflecting by discussions. The preparation of this study includes some learning material according to temperature and heat; the observation form that led by observer teachers; teachers’s model impression and open questionnaire implementation of lesson study that applied to the students and teachers. This research got some information about the strengths and weaknesses of learning using lesson study from the students involved. To conclude, the implementation of lesson study should be able to support the principle of collaborative in learning. The challenge of this study is how to make a condition to gather some teachers in one school at a certain time because they have the schedule at their own school.

2010-01-01

Tests of the spectrometer solenoids have taught us some important lessons. The spectrometer magnet lessons learned fall into two broad categories that involve the two stages of the coolers that are used to cool the magnets. On the first spectrometer magnet, the problems were centered on the connection of the cooler 2nd-stage to the magnet cold mass. On the first test of the second spectrometer magnet, the problems were centered on the cooler 1st-stage temperature and its effect on the operation of the HTS leads. The second time the second spectrometer magnet was tested; the cooling to the cold mass was still not adequate. The cryogenic designs of the MICE and MuCOOL coupling magnets are quite different, but the lessons learned from the tests of the spectrometer magnets have affected the design of the coupling magnets.

Optics and optronics in university courses for officers of the Federal Armed Forces - special curricula and hands-on lessons vs. academic requirements

Science.gov (United States)

Hahlweg, Cornelius; Rothe, Hendrik

2016-09-01

For more than two decades lessons in optics, digital image processing and optronics are compulsory optional subjects and as such integral parts of the courses in mechanical engineering at the University of the Federal Armed Forces in Hamburg. They are provided by the Chair for Measurement and Information Technology. Historically, the curricula started as typical basic lessons in optics and digital image processing and related sensors. Practical sessions originally concentrated on image processing procedures in Pascal, C and later Matlab. They evolved into a broad portfolio of practical hands-on lessons in lab and field, including high-tech and especially military equipment, but also homemaker style primitive experiments, of which the paper will give a methodical overview. A special topic - as always with optics in education - is the introduction to the various levels of abstraction in conjunction with the highly complex and wide-ranging matter squeezed into only two trimesters - instead of semesters at civil universities - for an audience being subject to strains from both study and duty. The talk will be accompanied by striking multi-media material, which will be also part of the multi-media attachment of the paper.

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.

Anticipating students' reasoning and planning prompts in structured problem-solving lessons

Science.gov (United States)

Vale, Colleen; Widjaja, Wanty; Doig, Brian; Groves, Susie

2018-02-01

Structured problem-solving lessons are used to explore mathematical concepts such as pattern and relationships in early algebra, and regularly used in Japanese Lesson Study research lessons. However, enactment of structured problem-solving lessons which involves detailed planning, anticipation of student solutions and orchestration of whole-class discussion of solutions is an ongoing challenge for many teachers. Moreover, primary teachers have limited experience in teaching early algebra or mathematical reasoning actions such as generalising. In this study, the critical factors of enacting the structured problem-solving lessons used in Japanese Lesson Study to elicit and develop primary students' capacity to generalise are explored. Teachers from three primary schools participated in two Japanese Lesson Study teams for this study. The lesson plans and video recordings of teaching and post-lesson discussion of the two research lessons along with students' responses and learning are compared to identify critical factors. The anticipation of students' reasoning together with preparation of supporting and challenging prompts was critical for scaffolding students' capacity to grasp and communicate generality.

Development of X-33/X-34 Aerothermodynamic Data Bases: Lessons Learned and Future Enhancements

Science.gov (United States)

Miller, C. G.

2000-01-01

A synoptic of programmatic and technical lessons learned in the development of aerothermodynamic data bases for the X-33 and X-34 programs is presented in general terms and from the perspective of the NASA Langley Research Center Aerothermodynamics Branch. The format used is that of the "aerothermodynamic chain," the links of which are personnel, facilities, models/test articles, instrumentation, test techniques, and computational fluid dynamics (CFD). Because the aerodynamic data bases upon which the X-33 and X-34 vehicles will fly are almost exclusively from wind tunnel testing, as opposed to CFD, the primary focus of the lessons learned is on ground-based testing. The period corresponding to the development of X-33 and X-34 aerothermodynamic data bases was challenging, since a number of other such programs (e.g., X-38, X-43) competed for resources at a time of downsizing of personnel, facilities, etc., outsourcing, and role changes as NASA Centers served as subcontractors to industry. The impact of this changing environment is embedded in the lessons learned. From a technical perspective, the relatively long times to design and fabricate metallic force and moment models, delays in delivery of models, and a lack of quality assurance to determine the fidelity of model outer mold lines (OML) prior to wind tunnel testing had a major negative impact on the programs. On the positive side, the application of phosphor thermography to obtain global, quantitative heating distributions on rapidly fabricated ceramic models revolutionized the aerothermodynamic optimization of vehicle OMLs, control surfaces, etc. Vehicle designers were provided with aeroheating information prior to, or in conjunction with, aerodynamic information early in the program, thereby allowing trades to be made with both sets of input; in the past only aerodynamic data were available as input. Programmatically, failure to include transonic aerodynamic wind tunnel tests early in the assessment phase

Existing facilities and past practices: Lessons learned

International Nuclear Information System (INIS)

Huizenga, D.; Tonkay, D.W.; Owens, K.

2000-01-01

Article 12 of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) requires parties to the Joint Convention to review the safety of existing radioactive waste management facilities 'to ensure that, if necessary, all reasonably practicable improvements are made to upgrade the safety of such a facility'. Also required is a review of the results of past practices to determine 'whether any intervention is needed for reasons of radiation protection' and to consider whether the benefits of the intervention or remediation are sufficient, with regard to the costs and the impact on workers, the public and the environment. This paper discusses the experience of the United States Department of Energy in terms of the lessons learned from operating radioactive waste management facilities and from undertaking intervention or remedial action, and from decision making in an international context. Overarching safety principles are discussed, including integrating safety into all work practices and minimizing the generation of waste. Safety review lessons learned with existing facilities are discussed with respect to: applying new requirements to old facilities, taking a life-cycle perspective of waste management, improving high level waste facility management, and blending current and past practices with respect to the process used to arrive at decisions for intervention. Special emphasis is placed on the need to provide for early and substantive input from the involved regulatory agencies, Native American tribes, and those citizens and groups with an interest in the decisions. Examples of intervention decisions are discussed, including examples taken from uranium mill tailings operations, from cleanup of a former uranium processing plant site, from evaluation of pre-1970 buried 'transuranic waste' sites, and from decommissioning or closure of high level waste storage tanks. The paper concludes that on the

2016-01-01

-cost subcontractors can turn out to be much more expensive due to interface proliferation. Other negative effects are social dumping by external contractors and loss of competence if procurement requirements are not taking quality and safety issues into account. Based on MTO Safety’s extensive experience in the nuclear domain and work on safety management and safety culture in the aviation, railway and maritime domain, the paper will present lessons learned which are applicable to the nuclear industry for facing the major challenges ahead. Assuring safety is a fundamental requirement for obtaining a licence to operate a business in nuclear power, aviation and railways, thus safety culture is an essential requirement for a successful business. Therefore safety culture must be part of any new business model in high risk industries. In the future safety culture and leadership commitment and skills in creating safety culture will be even more important. The paper will discuss how companies and public utilities are to achieve this and how the regulators are to assess this where learning across industries is a key success factor. (author)

We describe an example of learning with multiple representations in an A-level revision lesson on mechanics. The context of the problem involved the motion of a ball thrown vertically upwards in air and studying how the associated physical quantities changed during its flight. Different groups of students were assigned to look at the ball's motion using various representations: motion diagrams, vector diagrams, free-body diagrams, verbal description, equations and graphs, drawn against time as well as against displacement. Overall, feedback from students about the lesson was positive. We further discuss the benefits of using computer simulation to support and extend student learning.

The Patient Protection and Affordable Care Act establishes a new Center for Medicare and Medicaid Innovation in the Centers for Medicare and Medicaid Services (CMS). The center is intended to enhance the CMS's role in promoting much-needed improvements in payment and service delivery. Lessons from the Medicare Health Support Program, a chronic care pilot program that ran between 2005 and 2008, illustrate the value of drawing on experience in planning for the center and future pilot programs. The lessons include the importance of strong leadership; collaboration and flexibility to foster innovation; receptivity of beneficiaries to care management; and the need for timely data on patients' status. The lessons also highlight pitfalls to be avoided in planning future pilot programs, such as flawed strategies for selecting populations to target when testing payment and service delivery reforms.

Transition and Closeout of the Former DOE Mound Plant Site: Lessons Learned

International Nuclear Information System (INIS)

Carpenter, C. P.; Marks, M. L.; Smiley, S.L.; Gallaher, D. M.

2006-01-01

The U.S. Department of Energy's (DOE's) Office of Environmental Management (EM) manages the Miamisburg Closure Project (MCP) by cleaning up the Mound site, located in Miamisburg, Ohio, to specific environmental standards, conveying all excess land parcels to the Miamisburg Mound Community Improvement Corporation, and transferring all continuing DOE post-closure responsibilities to the Office of Legacy Management (LM). Presently, the EM cleanup contract of the Mound site with CH2M Hill Mound Inc. is scheduled for completion on March 31, 2006. LM manages the Mound transition efforts and also post-closure responsibilities at other DOE sites via a contract with the S.M. Stoller Corporation. The programmatic transfer from EM to LM is scheduled to take place on October 1, 2006. The transition of the Mound site has required substantial integration and coordination between the EM and LM. Several project management principles have been implemented to help facilitate the transfer of programmatic responsibility. As a result, several lessons learned have been identified to help streamline and improve integration and coordination of the transfer process. Lessons learned from the Mound site transition project are considered a work in progress and have been summarized according to a work breakdown structure for specific functional areas in the transition schedule. The functional areas include program management, environmental, records management, information technology, property management, stakeholder and regulatory relations, procurement, worker pension and benefits, and project closeout. Specific improvements or best practices have been recognized and documented by the Mound transition team. The Mound site is one of three major cleanup sites within the EM organization scheduled for completion in 2006. EM, EM cleanup contractor, LM, and LM post-closure contractor have identified lessons learned during the transition and closure of the Mound site. The transition effort from

International Nuclear Information System (INIS)

Anderson, D.R.; Chu, Margaret S.Y.; Froehlich, Gary K.; Howard, Bryan A.; Howarth, Susan M.; Larson, Kurt W.; Pickering, Susan Y.; Swift, Peter N.

1999-01-01

In May 1998, the US Environmental Protection Agency (EPA) certified the US Department of Energy's (DOE) Waste Isolation Pilot Plant (WIPP) as being in compliance with applicable long-term regulations governing the permanent disposal of spent nuclear fuel, high-level, and transuranic radioactive wastes. The WIPP is the first deep geologic repository in the US to have successfully demonstrated regulatory compliance with long-term radioactive waste disposal requirements. The first disposal of TRU waste at WIPP occurred on March 26, 1999. Many of the lessons learned during the WIPP Project's transition from site characterization and experimental research to the preparation of a successful application may be of general interest to other repository programs. During a four-year period (1992 to 1996), the WIPP team [including the DOE Carlsbad Area Office (CAO), the science advisor to CAO, Sandia National Laboratories (SNL), and the management and operating contractor of the WIPP site, Westinghouse Electric Corporation (WID)] met its aggressive schedule for submitting the application without compromising the integrity of the scientific basis for the long-term safety of the repository. Strong leadership of the CAO-SNL-WID team was essential. Within SNL, a mature and robust performance assessment (PA) allowed prioritization of remaining scientific activities with respect to their impact on regulatory compliance. Early and frequent dialog with EPA staff expedited the review process after the application was submitted. Questions that faced SNL are familiar to geoscientists working in site evaluation projects. What data should be gathered during site characterization? How can we know when data are sufficient? How can we know when our understanding of the disposal system is sufficient to support our conceptual models? What constitutes adequate ''validation'' of conceptual models for processes that act over geologic time? How should we use peer review and expert judgment? Other

Scheduling lessons learned from the Autonomous Power System

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.

The US Affiliated Pacific region's childhood obesity prevalence has reached epidemic proportions. To guide program and policy development, a multi-site study was initiated, in collaboration with partners from across the region, to gather comprehensive information on the regional childhood obesity prevalence. The environmental and cultural diversity of the region presented challenges to recruiting for and implementing a shared community-based, public health research program. This paper presents the strategies used to recruit families with young children (n = 5775 for children 2 - 8 years old) for obesity-related measurement across eleven jurisdictions in the US Affiliated Pacific Region. Data were generated by site teams that provided summaries of their recruitment strategies and lessons learned. Conducting this large multi-site prevalence study required considerable coordination, time and flexibility. In every location, local staff knowledgeable of the community was hired to lead recruitment, and participant compensation reflected jurisdictional appropriateness (e.g., gift cards, vouchers, or cash). Although recruitment approaches were site-specific, they were predominantly school-based or a combination of school- and community-based. Lessons learned included the importance of organization buy-in; communication, and advance planning; local travel and site peculiarities; and flexibility. Future monitoring of childhood obesity prevalence in the region should consider ways to integrate measurement activities into existing organizational infrastructures for sustainability and cost-effectiveness, while meeting programmatic (e.g. study) goals.

Lessons learned from Gen II NPP staffing approaches applicable to new reactors - 15003

International Nuclear Information System (INIS)

Goodnight, C.

2015-01-01

This paper discusses lessons learned from the operation of the Gen II fleet of existing nuclear power plants (NPPs), in terms of staffing, that can be applied to the final design, deployment, and operation of new reactor designs. The most significant of these lessons is the need to appropriately staff the facility, having the right number of people with the required skills and experience. This begs the question of how to identify those personnel requirements. For NPPs, there are five key factors that ultimately will determine the effectiveness and costs of operating nuclear power plants (NPPs): 1) The Nuclear Steam Supply System (NSSS) and the layout of the plant site; 2) The processes which the operating organization applies; 3) The organizational structure of the operating organization; 4) The organizational culture of the operating organization, and 5) The regulatory framework under which the licensee must operate. In summary, this paper identifies opportunities to minimize staffing and costs learned from Gen II NPPs that may be applicable for new nuclear plants. (author)

Satellite-instrument system engineering best practices and lessons

Science.gov (United States)

Schueler, Carl F.

2009-08-01

This paper focuses on system engineering development issues driving satellite remote sensing instrumentation cost and schedule. A key best practice is early assessment of mission and instrumentation requirements priorities driving performance trades among major instrumentation measurements: Radiometry, spatial field of view and image quality, and spectral performance. Key lessons include attention to technology availability and applicability to prioritized requirements, care in applying heritage, approaching fixed-price and cost-plus contracts with appropriate attention to risk, and assessing design options with attention to customer preference as well as design performance, and development cost and schedule. A key element of success either in contract competition or execution is team experience. Perhaps the most crucial aspect of success, however, is thorough requirements analysis and flowdown to specifications driving design performance with sufficient parameter margin to allow for mistakes or oversights - the province of system engineering from design inception to development, test and delivery.

UNLEARNED LESSONS OF CONTEMPORARY HISTORY

А Н Данилов

2017-12-01

Full Text Available The article considers the complex geopolitical situation in the global world at the end of the second decade of the 21st century as determined by the consequences of the collapse of the Soviet Union and by the new world order. The author seeks to answer the questions who will define the current geopolitical situation, whose aims it will reflect, what will become the basis of new geopolitical realities, the basis of moral solidarity of humankind, and the spiritual basis of future civilizations. The new challenges give rise to a desperate struggle for different scenarios for building a happy life. Moreover, it is not clear which ideal of the future world will be widely supported as a development guideline. The recognition as such of the standard of living and development of the strongest ones becomes a real threat to the new civilization for it leads to the loss of national interests of sovereign states, and to the loss of an independent future. Today, there is an active search for new theories and concepts that will adequately explain con-temporary global processes. In this thematic context, the author identifies main lessons not learned by the world political elites. The first lesson: new states are not born in an empty place, their common history is a great advantage ensuring prospects for the further development of interstate cooperation. The second lesson: the widespread falsification of history has a negative impact on national, cultural and social-group identity in transforming societies. The third lesson: after the collapse of the Soviet Union, the post-war balance of power was destroyed together with the system of checks and balances in world politics (a bipolar model of the world. The fourth lesson: under radical social transformations, the moral system of the population devaluates with numerous crisis consequences.

The FAIR timing master: a discussion of performance requirements and architectures for a high-precision timing system

International Nuclear Information System (INIS)

Kreider, M.

2012-01-01

Production chains in a particle accelerator are complex structures with many inter-dependencies and multiple paths to consider. This ranges from system initialization and synchronization of numerous machines to interlock handling and appropriate contingency measures like beam dump scenarios. The FAIR facility will employ White-Rabbit, a time based system which delivers an instruction and a corresponding execution time to a machine. In order to meet the deadlines in any given production chain, instructions need to be sent out ahead of time. For this purpose, code execution and message delivery times need to be known in advance. The FAIR Timing Master needs to be reliably capable of satisfying these timing requirements as well as being fault tolerant. Event sequences of recorded production chains indicate that low reaction times to internal and external events and fast, parallel execution are required. This suggests a slim architecture, especially devised for this purpose. Using the thread model of an OS or other high level programs on a generic CPU would be counterproductive when trying to achieve deterministic processing times. This paper deals with the analysis of said requirements as well as a comparison of known processor and virtual machine architectures and the possibilities of parallelization in programmable hardware. In addition, existing proposals at GSI will be checked against these findings. The final goal will be to determine the best instruction set for modeling any given production chain and devising a suitable architecture to execute these models. (authors)

Considerations for implementing an organizational lessons learned process.

Energy Technology Data Exchange (ETDEWEB)

Fosshage, Erik D

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.

Refining MARGINS Mini-Lessons Using Classroom Observations

Science.gov (United States)

Iverson, E. A.; Manduca, C. A.; McDaris, J. R.; Lee, S.

2009-12-01

One of the challenges that we face in developing teaching materials or activities from research findings is testing the materials to determine that they work as intended. Traditionally faculty develop material for their own class, notice what worked and didn’t, and improve them the next year. However, as we move to a community process of creating and sharing teaching materials, a community-based process for testing materials is appropriate. The MARGINS project has piloted such a process for testing teaching materials and activities developed as part of its mini-lesson project (http://serc.carleton.edu/margins/index.html). Building on prior work developing mechanisms for community review of teaching resources (e.g. Kastens, 2002; Hancock and Manduca, 2005; Mayhew and Hall, 2007), the MARGINS evaluation team developed a structured classroom observation protocol. The goals of field testing are to a) gather structured, consistent feedback for the lesson authors based on classroom use; b) guide reviewers of these lessons to reflect on research-based educational practice as a framework for their comments; c) collect information on the data and observations that the reviewer used to underpin their review; d) determine which mini-lessons are ready to be made widely available on the website. The protocol guides faculty observations on why they used the activity, the effectiveness of the activity in their classroom, the success of the activity in leading to the desired learning, and what other faculty need to successfully use the activity. Available online (http://serc.carleton.edu/margins/protocol.html), the protocol can be downloaded and completed during instruction with the activity. In order to encourage review of mini-lessons using the protocol, a workshop focused on review and revision of activities was held in May 2009. In preparation for the workshop, 13 of the 28 participants chose to field test a mini-lesson prior to the workshop and reported that they found this

The pre-conditions of engagement and actual engagement were examined using a novel research method to obtain detailed information on Finnish students’ engagement in different situations and to gain a better understanding of this phenomenon. The study’s participants consisted of 68 students (31 girls, 37 boys from 9th grade and 67 students (46 girls, 21 boys from 1st grade in upper secondary school. The research aimed to answer the following question: How does Finnish students’ engagement occur in exact and life science lessons? Participants received smartphones equipped with a smartphone application that included an experience sampling method questionnaire. The smartphones were programmed to emit a signal during every science lesson and otherwise randomly during the day (from 8 am to 8 pm. The results reveal that situation and grade had significant effects on students’ pre-conditions of engagement and actual engagement. Our results also show that girls had the highest interest in life science lessons and boys in exact science lessons.

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

Science.gov (United States)

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.

2006-01-01

This study documents the investigation of qualitative habitability and human factors feedback provided by scientists, engineers, and crewmembers on lessons learned from the ISS Program. A thorough review and understanding of this data is critical in charting NASA's future path in space exploration. NASA has been involved in ensuring that the needs of crewmembers to live and work safely and effectively in space have been met throughout the ISS Program. Human factors and habitability data has been collected from every U.S. crewmember that has resided on the ISS. The knowledge gained from both the developers and inhabitants of the ISS have provided a significant resource of information for NASA and will be used in future space exploration. The recurring issues have been tracked and documented; the top 5 most critical issues have been identified from this data. The top 5 identified problems were: excessive onsrbit stowage; environment; communication; procedures; and inadequate design of systems and equipment. Lessons learned from these issues will be used to aid in future improvements and developments to the space program. Full analysis of the habitability and human factors data has led to the following recommendations. It is critical for human factors to be involved early in the design of space vehicles and hardware. Human factors requirements need to be readdressed and redefined given the knowledge gained during previous ISS and long-duration space flight programs. These requirements must be integrated into vehicle and hardware technical documentation and consistently enforced. Lastly, space vehicles and hardware must be designed with primary focus on the user/operator to successfully complete missions and maintain a safe working environment. Implementation of these lessons learned will significantly improve NASA's likelihood of success in future space endeavors.

Vacuum-venipuncture skills: time required and importance of tube order

Full Text Available Chieko FujiiFaculty of Nursing and Medical Care, Keio University, Fujisawa, JapanBackground: The purpose of this study was to assess specific vacuum-venipuncture skills and the influence of the time involved in skin puncture and blood collection.Methods: Thirty subjects undergoing venipuncture in which video analysis was possible were included. These procedures were carried out by four nurses and recorded with a digital camera. Venipuncture skills classified by our observations were delineated on the basis of frame-by-frame video images, and a graph of x and y coordinates was created.Results: With the first blood-collection tube, strong blood flow required the practitioner to push the tube back in to compensate for the strong repulsive force in approximately 46% of cases. By the third blood-collection tube, the blood flow had weakened; therefore, the tube was moved up and down. In cases that required a second venipuncture, the tube was already pierced, so the time required to fill it to 5 mL was significantly longer.Conclusion: Hand movement of the practitioner is adjusted according to blood flow. Reflex movement in response to strong blood flow may increase the risk of pushing the needle through the vein with excessive force. The time required to fill the tube varies among nurses, tube order, and level of venipuncture skills.Keywords: blood collection, blood-collection tube, clinical practice, venipuncture skill

Yulianto, B.; Kamidjan; Ahmadi, A.; Asteria, P. V.

2018-01-01

The developmental research was motivated by the results of preliminary study through interviews, which revealed almost all of the teachers did not create lesson plan themselves. As a result of this load, the performance of the real learning in the classroom becomes inadequate. Moreover, when lesson plan was not made by teachers themselves, the learning process becomes ineffective. Therefore, this study designed to develop a prototype of the short lesson plan, in particular, Indonesian language teaching, and to investigate its effectiveness. The participants in the study were teachers who were trained through lesson study group to design short model’s lesson plan. Questionnaires and open-ended questions were used, and the quantitative and qualitative data obtained were analyzed accordingly. The analysis of the quantitative data, aided with SPSS, were frequency, percentage, and means, whereas the qualitative data were analyzed descriptively. The results showed that the teachers liked the model, and they were willing to design their own lesson plan. The observation data revealed that the classroom learning process became more interactive, and classroom atmosphere was more engaging and natural because the teachers did not stick to the lesson plan made by other teachers.

Risk communication in the case of the Fukushima accident: Impact of communication and lessons to be learned.

Science.gov (United States)

Perko, Tanja

2016-10-01

Risk communication about the Fukushima Daiichi nuclear power plant accident in 2011 was often not transparent, timely, clear, nor factually correct. However, lessons related to risk communication have been identified and some of them are already addressed in national and international communication programmes and strategies. The Fukushima accident may be seen as a practice scenario for risk communication with important lessons to be learned. As a result of risk communication failures during the accident, the world is now better prepared for communication related to nuclear emergencies than it was 5 years ago The present study discusses the impact of communication, as applied during the Fukushima accident, and the main lessons learned. It then identifies pathways for transparent, timely, clear and factually correct communication to be developed, practiced and applied in nuclear emergency communication before, during, and after nuclear accidents.

Mbonye, Anthony K; Wamala, Joseph F; Nanyunja, Miriam; Opio, Alex; Makumbi, Issa; Aceng, Jane Ruth

2014-09-01

There has been a rapid spread of Ebola Viral Hemorrhagic disease in Guinea, Liberia and Sierra Leone since March 2014. Since this is the first time of a major Ebola outbreak in West Africa; it is possible there is lack of understanding of the epidemic in the communities, lack of experience among the health workers to manage the cases and limited capacities for rapid response. The main objective of this article is to share Uganda's experience in controlling similar Ebola outbreaks and to suggest some lessons that could inform the control of the Ebola outbreak in West Africa. The article is based on published papers, reports of previous Ebola outbreaks, response plans and experiences of individuals who have participated in the control of Ebola epidemics in Uganda. Lessons learnt: The success in the control of Ebola epidemics in Uganda has been due to high political support, effective coordination through national and district task forces. In addition there has been active surveillance, strong community mobilization using village health teams and other community resources persons, an efficient laboratory system that has capacity to provide timely results. These have coupled with effective case management and infection control and the involvement of development partners who commit resources with shared responsibility. Several factors have contributed to the successful quick containment of Ebola outbreaks in Uganda. West African countries experiencing Ebola outbreaks could draw some lessons from the Uganda experience and adapt them to contain the Ebola epidemic.

In preparation for the launches of the Galileo and Ulysses spacecraft, a very comprehensive aerospace nuclear safety program and flight safety review were conducted. A review of this work has highlighted a number of important lessons which should be considered in the safety analysis and review of future space nuclear systems. These lessons have been grouped into six general categories: (1) establishment of the purpose, objectives and scope of the safety process; (2) establishment of charters defining the roles of the various participants; (3) provision of adequate resources; (4) provision of timely peer-reviewed information to support the safety program; (5) establishment of general ground rules for the safety review; and (6) agreement on the kinds of information to be provided from the safety review process

Tuning Linux to meet real time requirements

Herbel, Richard S.; Le, Dang N.

2007-04-01

There is a desire to use Linux in military systems. Customers are requesting contractors to use open source to the maximal possible extent in contracts. Linux is probably the best operating system of choice to meet this need. It is widely used. It is free. It is royalty free, and, best of all, it is completely open source. However, there is a problem. Linux was not originally built to be a real time operating system. There are many places where interrupts can and will be blocked for an indeterminate amount of time. There have been several attempts to bridge this gap. One of them is from RTLinux, which attempts to build a microkernel underneath Linux. The microkernel will handle all interrupts and then pass it up to the Linux operating system. This does insure good interrupt latency; however, it is not free [1]. Another is RTAI, which provides a similar typed interface; however, the PowerPC platform, which is used widely in real time embedded community, was stated as "recovering" [2]. Thus this is not suited for military usage. This paper provides a method for tuning a standard Linux kernel so it can meet the real time requirement of an embedded system.

Schools play an important role in physical activity promotion for adolescents. The systematic review aimed to determine the proportion of secondary (middle and high) school physical education (PE) lesson time that students spend in moderate to vigorous physical activity (MVPA), and to assess if MVPA was moderated by school level (middle and high school), type of physical activity measurement and type of PE activities. A systematic search of nine electronic databases was conducted (PROSPERO2014:CRD42014009649). Studies were eligible if they were published between 2005 and 2014; written in English; assessed MVPA in PE lessons of secondary (middle and high) school students; and used a quantitative MVPA measure (i.e., accelerometry, heart rate monitoring, pedometers or observational measures). Two reviewers examined the retrieved articles, assessed risk of bias, and performed data extraction. Random effects meta-analysis was used to calculate a pooled estimate of the percent of PE lesson time spent in MVPA and to assess moderator effects where data allowed. The search yielded 5,132 potentially relevant articles; 28 articles representing 25 studies (7 middle and 18 high school) from seven countries were included. Twelve studies measured MVPA through observational measures, seven used accelerometers, five used heart rate monitors and four used pedometers (including three studies using a mix of measures). Meta-analysis of 15 studies found that overall, students spent a mean (95% CI) of 40.5% (34.8-46.2%) of PE in MVPA. Middle school students spent 48.6% (41.3-55.9%) of the lesson in MVPA (n = 5 studies) and high school students 35.9% (28.3-43.6%) (n = 10 studies). Studies measuring MVPA using accelerometers (n = 5) showed that students spent 34.7% (25.1-44.4%) of the lesson in MVPA, while 44.4% (38.3-50.5%) was found for lessons assessed via observation (n = 9), 43.1% (24.3-61.9%) of the lesson for a heart rate based study, and 35.9% (31.0-40.8%) for a

Full Text Available The US Affiliated Pacific region’s childhood obesity prevalence has reached epidemic proportions. To guide program and policy development, a multi-site study was initiated, in collaboration with partners from across the region, to gather comprehensive information on the regional childhood obesity prevalence. The environmental and cultural diversity of the region presented challenges to recruiting for and implementing a shared community-based, public health research program. This paper presents the strategies used to recruit families with young children (n = 5775 for children 2 – 8 years old for obesity-related measurement across eleven jurisdictions in the US Affiliated Pacific Region. Data were generated by site teams that provided summaries of their recruitment strategies and lessons learned. Conducting this large multi-site prevalence study required considerable coordination, time and flexibility. In every location, local staff knowledgeable of the community was hired to lead recruitment, and participant compensation reflected jurisdictional appropriateness (e.g., gift cards, vouchers, or cash. Although recruitment approaches were site-specific, they were predominantly school-based or a combination of school- and community-based. Lessons learned included the importance of organization buy-in; communication, and advance planning; local travel and site peculiarities; and flexibility. Future monitoring of childhood obesity prevalence in the region should consider ways to integrate measurement activities into existing organizational infrastructures for sustainability and cost-effectiveness, while meeting programmatic (e.g. study goals.

To report cases involving the placement of the wrong intraocular lens (IOL) at the time of cataract surgery where human error occurred. Retrospective small case series, convenience sample. Seven surgical cases. Institutional review of errors committed and subsequent improvements to clinical protocols. Lessons learned and changes in procedures adapted. The pathways to a wrong IOL are many but largely reflect some combination of poor surgical team communication, transcription error, lack of preoperative clarity in surgical planning or failure to match the patient, and IOL calculation sheet with 2 unique identifiers. Safety in surgery involving IOLs is enhanced both by strict procedures, such as an IOL-specific "time-out," and the fostering of a surgical team culture in which all members are encouraged to voice questions and concerns.

Lach, D.; Bolton, P.; Durbin, N.; Harty, R.

1994-08-01

In response to public concern about the cleanup of the Three Mile Island, Unit 2 (TMI-2) facility after an accident on March 28, 1979 involving a loss of reactor coolant and subsequent damage to the reactor fuel, twelve citizens were asked to serve on an independent Advisory Panel to consult with the Nuclear Regulatory Commission (NRC) on the decontamination and cleanup of the facility. The panel met 78 times over a period of thirteen years, holding public meetings in the vicinity of TMI-2 and meeting regularly with NRC Commissioners in Washington, DC. This report describes the results of a project designed to identify and describe the lessons learned from the Advisory Panel and place those lessons in the context of what we generally know about citizen advisory groups. A summary of the empirical literature on citizen advisory panels is followed by a brief history of the TMI-2 Advisory Panel. The body of the report contains the analysis of the lessons learned, preliminary conclusions about the effectiveness of the Panel, and implications for the NRC in the use of advisory panels. Data for the report include meeting transcripts and interviews with past and present Panel participants

Mission reliability of semi-Markov systems under generalized operational time requirements

International Nuclear Information System (INIS)

Wu, Xiaoyue; Hillston, Jane

2015-01-01

Mission reliability of a system depends on specific criteria for mission success. To evaluate the mission reliability of some mission systems that do not need to work normally for the whole mission time, two types of mission reliability for such systems are studied. The first type corresponds to the mission requirement that the system must remain operational continuously for a minimum time within the given mission time interval, while the second corresponds to the mission requirement that the total operational time of the system within the mission time window must be greater than a given value. Based on Markov renewal properties, matrix integral equations are derived for semi-Markov systems. Numerical algorithms and a simulation procedure are provided for both types of mission reliability. Two examples are used for illustration purposes. One is a one-unit repairable Markov system, and the other is a cold standby semi-Markov system consisting of two components. By the proposed approaches, the mission reliability of systems with time redundancy can be more precisely estimated to avoid possible unnecessary redundancy of system resources. - Highlights: • Two types of mission reliability under generalized requirements are defined. • Equations for both types of reliability are derived for semi-Markov systems. • Numerical methods are given for solving both types of reliability. • Simulation procedure is given for estimating both types of reliability. • Verification of the numerical methods is given by the results of simulation

The impacts of climate change are a critical societal challenge of the 21st century. Educating students about the globally connected climate system is key in supporting the development of mitigation and adaptation strategies. Systems thinking is required for students to understand the complex, dynamic climate systems and the role that humans play within them. The interdisciplinary nature of climate science challenges educators, who often don't have formal training in climate science, to identify resources that are scientifically accurate before weaving them together into units that teach about the climate system. The Climate Literacy and Energy Awareness Network (CLEAN) supports this work by providing over 700 peer-reviewed, classroom-ready resources on climate and energy topics. The resource collection itself provide only limited instructional guidance, so educators need to weave the resources together to build multi-dimensional lessons that develop systems thinking skills. The Next Generation Science Standards (NGSS) science standards encourage educators to teach science in a 3-dimensional approach that trains students in systems thinking. The CLEAN project strives to help educators design NGSS-style, three-dimensional lessons about the climate system. Two approaches are currently being modeled on the CLEAN web portal. The first is described in the CLEAN NGSS "Get Started Guide" which follows a step-by-step process starting with the Disciplinary Core Idea and then interweaves the Cross-Cutting Concepts (CCC) and the Science and Engineering Practices (SEP) based on the teaching strategy chosen for the lesson or unit topic. The second model uses a climate topic as a starting place and the SEP as the guide through a four-step lesson sequence called "Earth Systems Investigations". Both models use CLEAN reviewed lessons as the core activity but provide the necessary framework for classroom implementation. Sample lessons that were developed following these two

2012-10-01

The aim of this study was to compare the coincidence-anticipation timing accuracy of athletes of different racket sports with various stimulus velocity requirements. Ninety players (15 girls, 15 boys for each sport) from tennis (M age = 12.4 yr., SD = 1.4), badminton (M age = 12.5 yr., SD = 1.4), and table tennis (M age = 12.4 yr., SD = 1.2) participated in this study. Three different stimulus velocities, low, moderate, and high, were used to simulate the velocity requirements of these racket sports. Tennis players had higher accuracy when they performed under the low stimulus velocity compared to badminton and table tennis players. Badminton players performed better under the moderate speed comparing to tennis and table tennis players. Table tennis players had better performance than tennis and badminton players under the high stimulus velocity. Therefore, visual and motor systems of players from different racket sports may adapt to a stimulus velocity in coincidence-anticipation timing, which is specific to each type of racket sports.

Mathematics teachers’ reflective practice within the context of adapted lesson study

Directory of Open Access Journals (Sweden)

Barbara Posthuma

2012-11-01

Full Text Available There seems to be paucity of research in South Africa on mathematics teachers’ reflective practice. In order to study this phenomenon, the context of lesson study (in an adapted form was introduced to five mathematics teachers in a rural school in the Free State. The purpose was to investigate their reflective practice whilst they collaboratively planned mathematics lessons and reflected on the teaching of the lessons. Data were obtained through interviews, video-recorded lesson observations, field notes taken during the lesson study group meetings and document analyses (lesson plans and reflective writings. The adapted lesson study context provided a safe space for teachers to reflect on their teaching and they reported an increase in self-knowledge and finding new ways of teaching mathematics to learners. This finding has some potential value for planning professional learning programmes in which teachers are encouraged to talk about their classroom experiences, share their joys and challenges with one another and strive to build a community of reflective practitioners to enhance their learners’ understanding of mathematics.

Lessons Learned from a Decade of Sudden Oak Death in California: Evaluating Local Management

Alexander, Janice; Lee, Christopher A.

2010-09-01

Sudden Oak Death has been impacting California’s coastal forests for more than a decade. In that time, and in the absence of a centrally organized and coordinated set of mandatory management actions for this disease in California’s wildlands and open spaces, many local communities have initiated their own management programs. We present five case studies to explore how local-level management has attempted to control this disease. From these case studies, we glean three lessons: connections count, scale matters, and building capacity is crucial. These lessons may help management, research, and education planning for future pest and disease outbreaks.

Incentive regulation of electricity distribution networks: Lessons of experience from Britain

International Nuclear Information System (INIS)

Jamasb, Tooraj; Pollitt, Michael

2007-01-01

This paper reviews the recent experience of the UK electricity distribution sector under incentive regulation. The UK has a significant and transparent history in implementing incentive regulation in the period since 1990. We demonstrate the successes of this period in reducing costs, prices, and energy losses while maintaining quality of service. We also draw out the lessons for other countries in implementing distribution sector reform. We conclude by discussing the place of incentive regulation of networks within the wider reform context, the required legislative framework, the need for appropriate unbundling, the importance of quality of service incentives, the regulatory information requirements, and the role of sector rationalisation.

Sustaining Lesson Study: Resources and Factors that Support and Constrain Mathematics Teachers' Ability to Continue After the Grant Ends

Science.gov (United States)

Druken, Bridget Kinsella

Lesson study, a teacher-led vehicle for inquiring into teacher practice through creating, enacting, and reflecting on collaboratively designed research lessons, has been shown to improve mathematics teacher practice in the United States, such as improving knowledge about mathematics, changing teacher practice, and developing communities of teachers. Though it has been described as a sustainable form of professional development, little research exists on what might support teachers in continuing to engage in lesson study after a grant ends. This qualitative and multi-case study investigates the sustainability of lesson study as mathematics teachers engage in a district scale-up lesson study professional experience after participating in a three-year California Mathematics Science Partnership (CaMSP) grant to improve algebraic instruction. To do so, I first provide a description of material (e.g. curricular materials and time), human (attending district trainings and interacting with mathematics coaches), and social (qualities like trust, shared values, common goals, and expectations developed through relationships with others) resources present in the context of two school districts as reported by participants. I then describe practices of lesson study reported to have continued. I also report on teachers' conceptions of what it means to engage in lesson study. I conclude by describing how these results suggest factors that supported and constrained teachers' in continuing lesson study. To accomplish this work, I used qualitative methods of grounded theory informed by a modified sustainability framework on interview, survey, and case study data about teachers, principals, and Teachers on Special Assignment (TOSAs). Four cases were selected to show the varying levels of lesson study practices that continued past the conclusion of the grant. Analyses reveal varying levels of integration, linkage, and synergy among both formally and informally arranged groups of

Lessons learned from decommissioning projects at Los Alamos National Laboratory

International Nuclear Information System (INIS)

Salazar, M.

1995-01-01

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

Mckirdy, Ian

2011-01-01

This document presents a reconciliation of the lessons learned during a 2010 comprehensive evaluation of pertinent lessons learned from past and present high temperature gas-cooled reactors that apply to the Next Generation Nuclear Plant Project along with current and planned activities. The data used are from the latest Idaho National Laboratory research and development plans, the conceptual design report from General Atomics, and the pebble bed reactor technology readiness study from AREVA. Only those lessons related to the structures, systems, and components of the Next Generation Nuclear Plant (NGNP), as documented in the recently updated lessons learned report are addressed. These reconciliations are ordered according to plant area, followed by the affected system, subsystem, or component; lesson learned; and finally an NGNP implementation statement. This report (1) provides cross references to the original lessons learned document, (2) describes the lesson learned, (3) provides the current NGNP implementation status with design data needs associated with the lesson learned, (4) identifies the research and development being performed related to the lesson learned, and (5) summarizes with a status of how the lesson learned has been addressed by the NGNP Project.

Space Mechanisms Lessons Learned and Accelerated Testing Studies

Science.gov (United States)

Fusaro, Robert L.

1997-01-01

A number of mechanism (mechanical moving component) failures and anomalies have recently occurred on satellites. In addition, more demanding operating and life requirements have caused mechanism failures or anomalies to occur even before some satellites were launched (e.g., during the qualification testing of GOES-NEXT, CERES, and the Space Station Freedom Beta Joint Gimbal). For these reasons, it is imperative to determine which mechanisms worked in the past and which have failed so that the best selection of mechanically moving components can be made for future satellites. It is also important to know where the problem areas are so that timely decisions can be made on the initiation of research to develop future needed technology. To chronicle the life and performance characteristics of mechanisms operating in a space environment, a Space Mechanisms Lessons Learned Study was conducted. The work was conducted by the NASA Lewis Research Center and by Mechanical Technologies Inc. (MTI) under contract NAS3-27086. The expectation of the study was to capture and retrieve information relating to the life and performance of mechanisms operating in the space environment to determine what components had operated successfully and what components had produced anomalies.

This study focuses on the effects of collaborative lesson planning by science pre-service teachers on their attitudes and knowledge. In our study, 120 pre-service teachers discussed a preparation for a science inquiry lesson in dyads. The teacher with the lesson preparation had the role of the coachee, while the other was the coach. We investigated the following research questions: (1) Does learning occur between the two peers? and (2) Is the competency in lesson planning affected by the attitude and knowledge of coach and coachee? Based on an actor-partner interdependence model (APIM), we could clarify the relations of pedagogical content knowledge (PCK) and attitudes (ATT) between and within the dyads of coach and coachee, as well as their development over time. Furthermore, the APIM allowed the inclusion of a mediator (lesson planning competency). Both PCK and ATT increased slightly but significantly during our project. ATT and PCK seemed to converge between coach and coachee at the end of the project. However, we could not find any cross-lagged effects, meaning there was no effect of coach on coachee or vice versa over time. Further, preceding PCK showed a significant effect on the competency of lesson planning, but planning competency did not influence succeeding PCK or attitude. Finally, these results are discussed with respect to science teacher education.

The study aimed to develop primary school science lesson plan based on inquiry cycle (5Es) through lesson study. The study focused on the development of 4 primary school science lesson plans of force and motion for Grade 3 students in KKU Demonstration Primary School (Suksasart), first semester of 2015 academic year. The methodology is mixed method. The Inthaprasitha (2010) lesson study cycle was implemented in group of KKU Demonstration Primary School. Instruments of reflection of lesson plan developing included participant observation, meeting and reflection report, lesson plan and other document. The instruments of examining students' learning include classroom observation and achievement test. Data was categorized from these instruments to find the issues of changing and improving the good lesson plan of Thai primary school science learning. The findings revealed that teachers could develop the lesson plans through lesson study. The issues of changing and improving were disused by considering on engaging students related to societal issues, students' prior knowledge, scientific concepts for primary school students, and what they learned from their changing. It indicated that the Lesson Study allowed primary school science teachers to share ideas and develop ideas to improve the lesson. The study may have implications for Thai science teacher education through Lesson Study.

ELPSA AS A LESSON DESIGN FRAMEWORK

Directory of Open Access Journals (Sweden)

Tom Lowrie

2015-07-01

Full Text Available This paper offers a framework for mathematics lesson design that is consistent with the way we learn about, and discover, most things in life. In addition, the framework provides a structure for identifying how mathematical concepts and understanding are acquired and developed. This framework is called ELPSA and represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. This framework has been used in developing lessons and teacher professional programs in Indonesia since 2012 in cooperation with the World Bank. This paper describes the theory that underlines the framework in general and in relation to each inter-connected component. Two explicit learning sequences for classroom practice are described, associated with Pythagoras theorem and probability. This paper then concludes with recommendations for using ELPSA in various institutional contexts.Keywords: ELPSA, lesson design framework, Pythagoras theorem, probability DOI: dx.doi.org/10.22342/jme.62.77

Development of a Base Frame for the New Fire PSA Training, and Lessons Learned

International Nuclear Information System (INIS)

Kim, Kilyoo; Kang, DaeIl; Kim, Wee Kyoung

2014-01-01

US NRC/EPRI issued a new fire PSA method represented by NUREG/CR 6850, and since it is about time to introduce the new fire PSA method as a regulatory requirement for the fire protection in Korea, a simple and easy-understandable base model for the fire PSA training is required, and thus KAERI-KINS jointly prepared a base model for the new fire PSA training last year. In this year, as a base frame development, fire ignition frequencies and severity factors, which were assumed in developing of the base model, are calculated. The fire modeling is performed to get the severity factor. This paper describes how the base frame is developed. Using an imaginary simple NPP, a base frame of fire PSA following the new fire PSA method was developed, and with which two days training course was provided twice for the plant engineers and regulators. Several lessons learned from the training are described. The two methods in quantification, i.e., CCDP method and initiator method are described

2018-04-25

Estimates of dietary requirements for vitamin D or Dietary Reference Values (DRV) are crucial from a public health perspective in providing a framework for prevention of vitamin D deficiency and optimizing vitamin D status of individuals. While these important public health policy instruments were developed with the evidence-base and data available at the time, there are some issues that need to be clarified or considered in future iterations of DRV for vitamin D. This is important as it will allow for more fine-tuned and truer estimates of the dietary requirements for vitamin D and thus provide for more population protection. The present review will overview some of the confusion that has arisen in relation to the application and/or interpretation of the definitions of the Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA). It will also highlight some of the clarifications needed and, in particular, how utilization of a new approach in terms of using individual participant-level data (IPD), over and beyond aggregated data, from randomised controlled trials with vitamin D may have a key role in generating these more fine-tuned and truer estimates, which is of importance as we move towards the next iteration of vitamin D DRVs.

MAVEN Information Security Governance, Risk Management, and Compliance (GRC): Lessons Learned

Science.gov (United States)

Takamura, Eduardo; Gomez-Rosa, Carlos A.; Mangum, Kevin; Wasiak, Fran

2014-01-01

As the first interplanetary mission managed by the NASA Goddard Space Flight Center, the Mars Atmosphere and Volatile EvolutioN (MAVEN) had three IT security goals for its ground system: COMPLIANCE, (IT) RISK REDUCTION, and COST REDUCTION. In a multiorganizational environment in which government, industry and academia work together in support of the ground system and mission operations, information security governance, risk management, and compliance (GRC) becomes a challenge as each component of the ground system has and follows its own set of IT security requirements. These requirements are not necessarily the same or even similar to each other's, making the auditing of the ground system security a challenging feat. A combination of standards-based information security management based on the National Institute of Standards and Technology (NIST) Risk Management Framework (RMF), due diligence by the Mission's leadership, and effective collaboration among all elements of the ground system enabled MAVEN to successfully meet NASA's requirements for IT security, and therefore meet Federal Information Security Management Act (FISMA) mandate on the Agency. Throughout the implementation of GRC on MAVEN during the early stages of the mission development, the Project faced many challenges some of which have been identified in this paper. The purpose of this paper is to document these challenges, and provide a brief analysis of the lessons MAVEN learned. The historical information documented herein, derived from an internal pre-launch lessons learned analysis, can be used by current and future missions and organizations implementing and auditing GRC.

Legislative Process For National Atomic Energy Laws Various Legal Approaches And Lessons Learned

International Nuclear Information System (INIS)

Ali, A.M.

2008-01-01

Legislative Process for National Atomic Energy Laws (NAELs) aim at establishing a legal base for the peaceful uses of nuclear energy. Various approaches (partial and comprehensive) to draft the NAELs are studied. The paper also studies some national nuclear energy laws through a comparative legal analysis and the important developments that have taken place in the legislative process for NAELs. There are lessons learned from the legislative process for NAELs. First, each state must develop its own legislative framework based on its own situation. Second, although the NAELs have common features, they vary considerably due to national legal traditions, social, economic circumstances and cultural values. Third, the NAELs have also evolved in time. Fourth, the technical standards, rules and guidelines should not be part of legislation issued by the Parliament because they would also facilitate quick adaption to new technical developments. Fifth, interface between legal and technical issues, requiring legal and technical experts to interact with each other. Sixth, continuing assessment that may lead to amendments to the law over time

2009-12-01

Cosmic Times tells the story of how our understanding of the nature of the universe has changed over the past 100 years. Designed to fulfill the need for quality science literature in the classroom, Cosmic Times takes the form of six posters, each mimicking the front page of a newspaper at a key point in this history, with articles describing the discoveries. These milestones include the confirmation of Einstein’s theory of gravity, Hubble’s evidence for an expanding universe, the detection of the microwave background, and finally the discovery of dark energy. Telling this story also involves tracing astronomer’s efforts to determine the size of the universe, understand the nature of supernovae, and comprehend the expansion of the universe. Through the scope of this history, students experience the process of science and how new technology and data change our ideas. The posters are accompanied by 28 lessons, designed for grades 7-12 by scientists and teachers and field-tested by third-party teachers in rural communities. The lessons teach the science concepts behind the discoveries, the process of science, and skills for science literacy. To facilitate these lessons and meet student’s individual science literacy needs, the articles are also available in two newsletter versions: one with the same articles as on the posters, the second at a slightly lower reading level. In addition, lessons include cross-curricular activities which explore the times and social circumstances of the discoveries. In a capstone lesson, students write and design the 2019 edition of Cosmic Times, not only predicting what we will know in the future, but also applying expository writing skills. In addition, an on-line Teacher Guide provides background material for all the articles. All these materials are available on the Cosmic Times website, http://cosmictimes.gsfc.nasa.gov/. In this presentation, we shall describe how Cosmic Times uses a journalistic storytelling approach to

Shiers, J D

2008-01-01

This paper summarises the main lessons learnt from deploying WLCG production services, with a focus on Reliability, Scalability, Accountability, which lead to both manageability and usability. Each topic is analysed in turn. Techniques for zero-user-visible downtime for the main service interventions are described, together with pathological cases that need special treatment. The requirements in terms of scalability are analysed, calling for as much robustness and automation in the service as possible. The different aspects of accountability - which covers measuring/tracking/logging/monitoring what is going on - and has gone on - is examined, with the goal of attaining a manageable service. Finally, a simple analogy is drawn with the Web in terms of usability - what do we need to achieve to cross the chasm from small-scale adoption to ubiquity?

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.

The key factors affecting students' individual interest in school science lessons

Science.gov (United States)

Cheung, Derek

2018-01-01

Individual interest in school science lessons can be defined as a relatively stable and enduring personal emotion comprising affective and behavioural reactions to events in the regular science lessons at school. Little research has compared the importance of different factors affecting students' individual interest in school science lessons. The present study aimed to address this gap, using a mixed methods design. Qualitative interview data were collected from 60 Hong Kong junior secondary school students, who were asked to describe the nature of their interest in science lessons and the factors to which they attribute this. Teacher interviews, parent interviews, and classroom observations were conducted to triangulate student interview data. Five factors affecting students' individual interest in school science lessons were identified: situational influences in science lessons, individual interest in science, science self-concept, grade level, and gender. Quantitative data were then collected from 591 students using a questionnaire. Structural equation modelling was applied to test a hypothesised model, which provided an acceptable fit to the student data. The strongest factor affecting students' individual interest in school science lessons was science self-concept, followed by individual interest in science and situational influences in science lessons. Grade level and gender were found to be nonsignificant factors. These findings suggest that teachers should pay special attention to the association between academic self-concept and interest if they want to motivate students to learn science at school.

How to learn and develop from both good and bad lessons- the 2011Tohoku tsunami case -

Science.gov (United States)

Sugimoto, Megumi; Okazumi, Toshio

2013-04-01

The 2011 Tohoku tsunami revealed Japan has repeated same mistakes in a long tsunami disaster history. After the disaster Japanese remember many old lessons and materials: an oral traditional evacuation method 'Tsunami TENDENKO' which is individual independent quick evacuation, a tsunami historical memorial stone "Don't construct houses below this stone to seaside" in Aneyoshi town Iwate prefecture, Namiwake-shrine naming from the story of protect people from tsunami in Sendai city, and so on. Tohoku area has created various tsunami historical cultures to descendent. Tohoku area had not had a tsunami disaster for 50 years after the 1960 Chilean tsunami. The 2010 Chilean tsunami damaged little fish industry. People gradually lost tsunami disaster awareness. At just the bad time the magnitude (M) 9 scale earthquake attacked Tohoku. It was for our generations an inexperienced scale disaster. People did not make use of the ancestor's lessons to survive. The 2004 Sumatra tsunami attacked just before 7 years ago. The magnitude scale is almost same as M 9 scale. Why didn't Tohoku people and Japanese tsunami experts make use of the lessons? Japanese has a character outside Japan. This lesson shows it is difficult for human being to learn from other countries. As for Three mile island accident case in US, it was same for Japan. To addition to this, there are similar types of living lessons among different hazards. For examples, nuclear power plantations problem occurred both the 2012 Hurricane Sandy in US and the 2011 Tohoku tsunami. Both local people were not informed about the troubles though Oyster creek nuclear power station case in US did not proceed seriously all. Tsunami and Hurricane are different hazard. Each exparts stick to their last. 1. It is difficult for human being to transfer living lessons through next generation over decades. 2. It is difficult for human being to forecast inexperienced events. 3. It is usually underestimated the danger because human being

The 2015 earthquake in Nepal killed over 8000 people, injured more than 21,000 and displaced a further 2 million. One year later, a national workshop was organized with various Nepali stakeholders involved in the response to the earthquake. The workshop provided participants an opportunity to reflect on their experiences and sought to learn lessons from the disaster. One hundred and thirty-five participants took part and most had been directly involved in the earthquake response. They included representatives from the Ministry of Health, local and national government, the armed forces, non-governmental organizations, health practitioners, academics, and community representatives. Participants were divided into seven focus groups based around the following topics: water, sanitation and hygiene, hospital services, health and nutrition, education, shelter, policy and community. Facilitated group discussions were conducted in Nepalese and the key emerging themes are presented. Participants described a range of issues encountered, some specific to their area of expertize but also more general issues. These included logistics and supply chain challenges, leadership and coordination difficulties, impacts of the media as well as cultural beliefs on population behaviour post-disaster. Lessons identified included the need for community involvement at all stages of disaster response and preparedness, as well as the development of local leadership capabilities and community resilience. A 'disconnect' between disaster management policy and responses was observed, which may result in ineffective, poorly planned disaster response. Finding time and opportunity to reflect on and identify lessons from disaster response can be difficult but are fundamental to improving future disaster preparedness. The Nepal Earthquake National Workshop offered participants the space to do this. It garnered an overwhelming sense of wanting to do things better, of the need for a Nepal-centric approach

'It ain't what you do it's the way that you do it': lessons for health care from decommissioning of older people's services.

Science.gov (United States)

Robinson, Suzanne; Glasby, Jon; Allen, Kerry

2013-11-01

Public sector organisations are facing one of the most difficult financial periods in history and local decision-makers are tasked with making tough rationing decisions. Withdrawing or limiting services is an emotive and complex task and something the National Health Service has always found difficult. Over time, local authorities have gained significant experience in the closure of care homes - an equally complex and controversial issue. Drawing on local knowledge and best practice examples, this article highlights lessons and themes identified by those decommissioning care home services. We believe that such lessons are relevant to those making disinvestment decisions across public sector services, including health-care. The study employed semi-structured interviews with 12 Directors of Adult Social Services who had been highlighted nationally as having extensive experience of home closures. Interviews were conducted over a 2-week period in March 2011. Results from the study found that having local policy guidance that is perceived as fair and reasonable was advocated by those involved in home closures. Many local policies had evolved over time and had often been developed following experiences of home closures (both good and bad). Decisions to close care home services require a combination of strong leadership, clear strategic goals, a fair decision-making process, strong evidence of the need for change and good communication, alongside wider stakeholder engagement and support. The current financial challenge means that public sector organisations need to make tough choices on investment and disinvestment decisions. Any such decisions need to be influenced by what we know constitutes best practice. Sharing lessons and experiences within and between sectors could well inform and develop decision-making practices. © 2013 John Wiley & Sons Ltd.

A History of Space Toxicology Mishaps: Lessons Learned and Risk Management

Science.gov (United States)

James, John T.

2009-01-01

After several decades of human spaceflight, the community of space-faring nations has accumulated a diverse and sometimes harrowing history of toxicological events that have plagued human space endeavors almost from the very beginning. Lessons have been learned in ground-based test beds and others were discovered the hard way - when human lives were at stake in space. From such lessons one can build a risk-management framework for toxicological events to minimize the probability of a harmful exposure, while recognizing that we cannot foresee all events. Space toxicologists have learned that relatively harmless compounds can be converted by air revitalization systems into compounds that cause serious harm to the crew. Our toxic risk management strategy now includes an assessment of the fate of any compound that might be released into the atmosphere. Propellants are highly toxic compounds, yet we have not always been able to thoroughly isolate the crew from exposure to these toxicants. Leakage of fluids from systems has resulted in hazardous conditions at times, and the behavior of such compounds inside a spacecraft has taught us how to manage potentially harmful escapes should they occur. Potential combustion events are an ever-present threat to the wellbeing of the crew. Such events have been sufficiently common that we have learned that one cannot judge the health threat of a given fire by the magnitude of the event. Management of such risks demands monitoring of combustion products. In the category of unpredictable toxic events, if one assumes that fires are predictable, we can place experience with toxic microbial metabolites, upsets during repair operations, and discharges from filters that have accumulated a substantial load of pollutants in their absorption beds. Management of such events requires a broad-spectrum, real-time analytical capability to discern the identity and concentrations of pollutants if they enter the atmosphere. Adverse events are an

Justification of response time testing requirements for pressure and differential pressure sensors

International Nuclear Information System (INIS)

Weiss, J.M.; Mayo, C.; Swisher, V.

1991-01-01

This paper reports on response time testing (RTT) requirements that were imposed on pressure, differential pressure sensors as a conservative approach to insure that assumptions in the plant safety analyses were met. The purpose of this project has been to identify the need for response time testing using the bases identified in IEEE Standard 338. A combination of plant data analyses, failure modes, and effects analyses (FMEAs) was performed. Eighteen currently qualified sensor models were utilized. The results of these analyses indicate that there are only two failure modes that affect response time, not sensor output concurrently. For these failure modes, appropriate plant actions and testing techniques were identified. Safety system RTT requirements were established by IEEE Standard 338-1975. Criteria for the Periodic Testing of Class IE Power, Protection Systems, presuming the need existed for this testing. This standard established guidelines for periodic testing to verify that loop response times of installed nuclear safety-related equipment were within the limits presumed by the design basis plant transient, accident analyses. The requirements covered all passive, active components in an instrument loop, including sensors.

Full Text Available Lesson Study as a growing interest in the education world has attracted educators, experts, and professionals in the area to make use of it in improving the lessons—it also happens in Indonesia. Originally applied in the teaching of mathematics in Japan, now it turns to be used in other fields, and English is one of them. This paper highlights the guideline on Lesson Study and pictures its application in a private senior high school in Malang, East Java, Indonesia. The adaptation of Lesson Study is interesting since Japan and Indonesia have different cultural background. How Lesson Study is usually implemented in Japan and the US and how it is applied in Indonesia will be seen here. As this is a case study, it will only focus on a school and the result should not be used to generalize Lesson Study applications in Indonesia. Interview and observation were instruments used in this study. The interview was used to gain information on how Lesson Study was normally conducted and observation (and the researchers’ involvements was used to see the real implementation of Lesson Study. What happened during the implementation of Lesson Study and during the teaching and learning process become a great attention here.

Lessons Learned from the Fukushima Daiichi Accident, Actions Taken and Challenges Ahead

International Nuclear Information System (INIS)

Shimizu, Y.

2016-01-01

On 19 September, 2012, the Nuclear Regulation Authority (NRA) was established in light of lessons learned from the Fukushima Daiichi accident of 11 March 2011, to ensure that such accidents never happen again, to restore public trust in regulator both in Japan and abroad and to rebuild and foster a genuine safety culture by placing the highest priority on public safety. The NRA, an independent administrative commission of the Ministry of the Environment, is organized to separate the regulatory functions from the promotional functions of the use of nuclear energy within the government, and to independently implement its duties from the perspectives of neutrality and fairness based on its expertise. Having learned the lessons from the Fukushima Daiichi accident and with reference to IAEA safety standards, since its establishment, the NRA has endeavored to strengthen the regulatory requirements, in particular, for hazards such as tsunamis and earthquakes which may lead to common cause failures, and countermeasures against severe accidents. Under the new regulatory scheme, a back-fitting system was introduced. Emergency preparedness and response measures for nuclear facilities were also enhanced. As of end of March 2016, five reactors received NRA’s permission for changing their reactor installations based on the new regulatory requirements, and two nuclear power reactors have restarted their operations. In January 2016, at the request of Japan, the IAEA sent the IRRS mission team to Japan to assess the regulatory framework for nuclear and radiation safety. Through the self-assessment prior to the mission, the NRA has developed 22 action plans, including a) improvement of regulatory inspection, b) capacity building, and c) strengthening of safety research capability. The mission team has found that Japan’s nuclear regulator has demonstrated independence and transparency since it was set up in 2012. The team also noted that the NRA needs to improve the inspection

Full Text Available This paper reports incidental acquisition of English nominal structures by a young EFL learner under comprehension-based lessons. The learner was exposed to a series of English sentences containing the target structures through listen-and-do activities. These activities required that the learner select different items based on the instructions given by the researcher. The exposure took place between 40 and 60 minutes in total spread over 3 days. In the fourth day, the learner was asked to give instructions (in English to the researcher to select particular items. The learner’s task performance was then transcribed and analyzed using complexity and accuracy measures. The results indicated that comprehension-based lessons were effective in facilitating incidental acquisition the target structures for the learner.

Full Text Available The notion of learner-centeredness has been embedded in the National Curriculum of Indonesia, 2013 Curriculum. However, most of the teachers seem to be hardly acquainted with the concept of Self-Regulated Learning (SRL and discovery learning in the lesson planning. Considering the phenomenon, this study intends to explore the concept of Self-Regulated Learning in the lesson plan of English subject for a tenth-grade level by employing a qualitative design with data obtained from a teacher-made lesson plan and a semi-structured interview. The researcher used content analysis to analyze the lesson plan. Meanwhile, the qualitative data from interview result were preceded through a coding sheet and transcribed modified figure. The findings revealed an integration of SRL cyclical phase and discovery learning in the teacher-made lesson plan. Based on the discussion, the results need to be applied in a considerably large context, in order to see thoroughly dynamic integration between Self-Regulated Learning model, lesson planning and the concept of learner autonomy.

Lessons from independence

Hauptfuhrer, R.R.

1990-01-01

The recent history of Oryx provides invaluable lessons for those who plan future energy strategies, relates the author of this paper. When Oryx became an independent oil and gas company, its reserves were declining, its stock was selling below asset values, and the price of oil seemed stuck below $15 per barrel. The message from Oryx management to Oryx employees was: We are in charge of our own destiny. We are about to create our own future. Oryx had developed a new, positive corporate culture and the corporate credit required for growth. This paper points to two basic principles that have guided the metamorphosis in Oryx's performance. The first objective was to improve operational efficiency and to identify the right performance indicators to measure this improvement. It states that the most critical performance indicator for an exploration and production company must be replacement and expansion of reserves at a competitive replacement cost. Oryx has cut its finding costs from $12 to $5 per barrel, while the BP acquisition provided proven reserves at a cost of only $4 per barrel. Another performance indicator measures Oryx's standing in the financial markets

O'Brien, J.H.; Kelly, D.L.

1995-11-01

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

Lessons of nuclear power

International Nuclear Information System (INIS)

Collingridge, D.

1984-01-01

In an earlier article the author has argued that the turbulent history of nuclear power in Britain and the USA stems from the technology itself, and has little to do with the very different institutional arrangements made for the new technology in the two countries. Nuclear plant has various features which make its planning extraordinarily difficult. Its long lead time, large unit size, capital intensity and dependence on complex infrastructure combine to ensure that mistakes are likely to be made in planning the technology and that what mistakes do occur are expensive. This article aims to expand on the earlier one in two ways; by looking at the apparent success of the French nuclear programme which seems to run counter to the thesis of the earlier article, and by trying to draw lessons from the earlier analysis for the breeder reactor.

Virtual surgical planning (VSP) is a tool for predicting complex surgical movements in three dimensions and it may reduce preoperative laboratory time. A prospective study to compare the time required for standard preoperative planning versus VSP was conducted at Massachusetts General Hospital from January 2014 through January 2015. Workflow data for bimaxillary cases planned by both standard techniques and VSP were recorded in real time. Time spent was divided into three parts: (1) obtaining impressions, face-bow mounting, and model preparation; (2) occlusal analysis and modification, model surgery, and splint fabrication; (3) online VSP session. Average times were compared between standard treatment planning (sum of parts 1 and 2) and VSP (sum of parts 1 and 3). Of 41 bimaxillary cases included, 20 were simple (symmetric) and 21 were complex (asymmetry and segmental osteotomies). Average times for parts 1, 2, and 3 were 4.43, 3.01, and 0.67h, respectively. The average time required for standard treatment planning was 7.45h and for VSP was 5.10h, a 31% time reduction (Porthognathic surgery cases.

2016-01-01

Full Text Available Background: Disasters have adverse impacts on different aspects of human life. Psychosocial Rehabilitation is one of the fields which is usually overshadowed and ignored by physical rehabilitation or its importance does not receive proper attention. This research attempts to study some lessons learned from Psychosocial Rehabilitation based on disaster experiences in Iran. Materials and Methods: This study has a conventional qualitative content analysis design. The participants of study were 15 people with direct experience of earthquake and 12 experts in this field. The study sample was selected by purposeful sampling method and the data were collected by semi-structured interviews. Results: Lack of a suitable system to deliver Psychosocial Rehabilitation, challenge in establishing balance between short-term and long-term social and mental needs, lack of mental and social experts, inefficiency in using social capital and capacities are the most important lessons learned in this field. Conclusion: Lack of awareness of mental and social problems of affected people after disaster is one of the most important barriers in successful and stable rehabilitation. Psychosocial Rehabilitation requires a suitable structure and planning for all stages of disaster management.

Motivation Matters: Lessons for REDD+ Participatory Measurement, Reporting and Verification from Three Decades of Child Health Participatory Monitoring in Indonesia.

Science.gov (United States)

Ekowati, Dian; Hofstee, Carola; Praputra, Andhika Vega; Sheil, Douglas

2016-01-01

Participatory Measurement, Reporting and Verification (PMRV), in the context of reducing emissions from deforestation and forest degradation with its co-benefits (REDD+) requires sustained monitoring and reporting by community members. This requirement appears challenging and has yet to be achieved. Other successful, long established, community self-monitoring and reporting systems may provide valuable lessons. The Indonesian integrated village healthcare program (Posyandu) was initiated in the 1980s and still provides effective and successful participatory measurement and reporting of child health status across the diverse, and often remote, communities of Indonesia. Posyandu activities focus on the growth and development of children under the age of five by recording their height and weight and reporting these monthly to the Ministry of Health. Here we focus on the local Posyandu personnel (kaders) and their motivations and incentives for contributing. While Posyandu and REDD+ measurement and reporting activities differ, there are sufficient commonalities to draw useful lessons. We find that the Posyandu kaders are motivated by their interests in health care, by their belief that it benefits the community, and by encouragement by local leaders. Recognition from the community, status within the system, training opportunities, competition among communities, and small payments provide incentives to sustain participation. We examine these lessons in the context of REDD+.

Human Systems Integration in Practice: Constellation Lessons Learned

Science.gov (United States)

Zumbado, Jennifer Rochlis

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.

Inadvertent weather modification urban areas - lessons for global climate change

Energy Technology Data Exchange (ETDEWEB)

Changnon, S A [Illinois State Water Survey, Champaign, IL (USA)

1992-05-01

Large metropolitan areas in North America, home to 65% of the USA's population, have created major changes in their climates over the past 150 years. The rate and amount of the urban climate change approximate those being predicted globally using climate models. Knowledge of urban weather and climate modification holds lessons for the global climate change issue. First, adjustments to urban climate changes can provide guidance for adjusting to global change. A second lesson relates to the difficulty but underscores the necessity of providing scientifically credible proof of change within the noise of natural climatic variability. The evolution of understanding about how urban conditions influence weather reveals several unexpected outcomes, particularly relating to precipitation changes. These suggest that similar future surprises can be expected in a changed global climate, a third lesson. In-depth studies of how urban climate changes affected the hydrologic cycle, the regional economy, and human activities were difficult because of data problems, lack of impact methodology, and necessity for multidisciplinary investigations. Similar impact studies for global climate change will require diverse scientific talents and funding commitments adequate to measure the complexity of impacts and human adjustments. Understanding the processes whereby urban areas and other human activities have altered the atmosphere and changed clouds and precipitation regionally appears highly relevant to the global climate-change issue. Scientific and governmental policy development needs to recognize an old axiom that became evident in the studies of inadvertent urban and regional climate change and their behavioural implications: Think globally but act locally. Global climate change is an international issue, and the atmosphere must be treated globally. But the impacts and the will to act and adjust will occur regionally.

Lessons learned by southern states in designating alternative routes

International Nuclear Information System (INIS)

1989-08-01

The purpose of this report is to discuss the ''lessons learned'' by the five states within the southem region that have designated alternative or preferred routes under the regulations of the Department of Transportation (DOT) established for the transportation of radioactive materials. The document was prepared by reviewing applicable federal laws and regulations, examining state reports and documents and contacting state officials and routing agencies involved in making routing decisions. In undertaking this project, the Southern States Energy Board hopes to reveal the process used by states that have designated alternative routes and thereby share their experiences (i.e., lessons learned) with other southern states that have yet to make designations. Under DOT regulations (49 CFR 177.826), carriers of highway route controlled quantities of radioactive materials (which include spent nuclear fuel and high-level waste) must use preferred routes selected to reduce time in transit. Such preferred routes consist of (1) an interstate system highway with use of an interstate system bypass or beltway around cities when available, and (2) alternate routes selected by a ''state routing agency.''

Strategic Program Planning Lessons Learned in Developing the LTS S&T Roadmap

Energy Technology Data Exchange (ETDEWEB)

Duane Hanson; Brent Dixon; Gretchen Matthern

2003-07-01

Technology roadmapping is a strategic planning method used by companies to identify and plan the development of technologies necessary for new products. The U.S. Department of Energy’s Office of Environmental Management has used this same method to refine requirements and identify knowledge and tools needed for completion of defined missions. This paper describes the process of applying roadmapping to clarify mission requirements and identify enhancing technologies for the Long-Term Stewardship (LTS) of polluted sites after site cleanup has been completed. The nature of some contamination problems is such that full cleanup is not achievable with current technologies and some residual hazards remain. LTS maintains engineered contaminant barriers and land use restriction controls, and monitors residual contaminants until they no longer pose a risk to the public or the environment. Roadmapping was used to clarify the breadth of the LTS mission, to identify capability enhancements needed to improve mission effectiveness and efficiency, and to chart out the research and development efforts to provide those enhancements. This paper is a case study of the application of roadmapping for program planning and technical risk management. Differences between the planned and actual application of the roadmapping process are presented along with lessons learned. Both the process used and lessons learned should be of interest for anyone contemplating a similar technology based planning effort.

NAPAP: A lesson in science, policy

International Nuclear Information System (INIS)

Russell, M.

1993-01-01

Perplexing environmental questions, such as acid rain and global warming, cry out for policy solutions based upon solid scientific evidence. Scientists and politicians agree on this but have trouble finding an effective way to do it. Milton Russell of the University of Tennessee and Oak Ridge National Laboratory describes a major, but only partially successful, effort that he believes contains valuable lessons for scientists and policy makers in the future. It is the National Acid Precipitation Assessment Program (NAPAP), launched in 1980 to generate the latest scientific evidence to guide national debate on clean-air legislation. The program open-quotes created an unprecedented body of scientific research on an environmental issue of the first order,close quotes Russell says. Yet, he admits, its influence was virtually nil on the legislation that ultimately emerged on the subject. Russell blames this lack of influence on NAPAP's failure to provide adequate assessment of its research findings, its failure to communicate the results on a timely and effective basis, and on open-quotes political forces that sought legislation rather than a full explication of issues.close quotes Out of the experience, Russell finds lessons for the future: open-quotes First, if the scientific finding are to have an impact on policy, assessment must become a priority as important as scientific research. Second, for projects designed to help decision makers, scientific research must be considered a resource, not an end product. Third, timely, lucid communication must be an essential element of the project, not a marginal activity.close quotes NAPAP, Russell concludes, open-quotes proved a long-term scientific success and a short-term policy disappointment.close quotes Then he warns, open-quotes Future science programs ignore the NAPAP experience at their own risk.close quotes

The use of tuberculin for the therapy of tuberculosis was attempted more than 100 years ago and abandoned because of its adverse reactions. In this historical review we point out that some of the intensive efforts to avoid the reactions were based on the best scientific rationale available at that time. Balancing the dosage and intervals of tuberculin delivery with clinical and laboratory monitoring of patients achieved a limited success, with implications, toward current research in the field. The role of economical and social aspects at that time is also a lesson to be learned toward current approaches to tuberculosis control. Copyright 2009 Elsevier Masson SAS. All rights reserved.

Governance of CO2 markets: Lessons from the EU ETS

International Nuclear Information System (INIS)

Perthuis, Christian de; Trotignon, Raphael

2014-01-01

The European emissions trading scheme (EU ETS) is the centerpiece of Europe's climate policy. The system has been undermined variously by the weakness of its regulation, an undesirable overlap with other public policies and the far-reaching economic and financial crisis that caused the market price of allowances to plunge. This article attempts to identify the conditions for making the coming years of the EU ETS a success. It draws historical lessons from the eight years the scheme has been in operation, and then presents the various interventions by the public authorities currently under discussion in order to revive the market. Finally, the article proposes to draw lessons from monetary policy by outlining what might be the mandate of an Independent Carbon Market Authority, with responsibility for the dynamic management of the supply of allowances, and whose main mission would be to ensure the optimal linkage between the different temporal horizons of the climate strategy. This article could provide important lessons for schemes developing in the rest of the world, especially in South Korea or in China. - Highlights: • History suggest that ex ante expectations tend to overestimate the constraint. • Economic conditions, policy overlaps, and Kyoto credits cause the current weakness. • “Set aside” or “backloading” does not resolve structural issues. • Changing/extending the reduction target is necessary but not sufficient. • An independent authority could ensure the credibility of the constraint over time

They include a non-intimidating forum for exchanging information, two-way communication, advance preparation to identify what each party wants to learn, and feedback. There is no single approach that guarantees success. Factors such as technical complexity of the issue, level of support by the public, and trust and confidence among the parties all play a role in determining the most workable approach for any particular situation. This paper illustrates lessons learned by the US Department of Energy (DOE) in communicating nuclear waste disposal and transportation issues to the public

The efficiency and effectivity of the learning experience is dependent on the teacher quality, thus, enhancing teacher's quality is vital in improving the students learning outcome. Since, the usual top-down one-shot cascading model practice for teachers' professional development in Philippines has been observed to have much information dilution, and the Southeast Asian Ministers of Education Organization demanded the need to develop mathematics teachers' quality standards through the Southeast Asia Regional Standards for Mathematics Teachers (SEARS-MT), thus, an intensive, ongoing professional development model should be provided to teachers. This study was undertaken to determine the impact of Lesson Study on Bulua National High School mathematics teachers' quality level in terms of SEARS-MT dimensions. A mixed method of quantitative-qualitative research design was employed. Results of the analysis revealed that Lesson Study effectively enhanced mathematics teachers' quality and promoted teachers professional development. Teachers positively perceived Lesson Study to be beneficial for them to become a better mathematics teacher.

The physical activity (PA) levels of many children and adolescents in Australia are currently insufficient to promote health benefits. Physical education (PE) programs aim to promote PA and reach nearly all school-aged children, but PA levels within PE lessons are often low. PE teachers may influence children's motivation to be physically active in PE lessons, but little is known about teacher strategies that effectively motivate children to participate in PA, and few intervention studies have examined motivational strategies in PE. The purpose of this study was to compare the effect of three motivational strategies, each based on Self-Determination Theory (SDT), on PA levels, and their hypothesized antecedents, during year 8 PE lessons. This study employed a cluster-randomized controlled trial design. Following a familiarization session, PA levels and hypothesized PA antecedents were measured during a baseline lesson and a post-intervention or control lesson. Teachers (n = 16) and their classes from five secondary schools in Sydney, Australia were randomly assigned into four blocks and instructed to provide one of four 20-min lesson teaching strategy conditions: (1) explaining the relevance of activities; (2) providing choice from PA options selected by the teacher; (3) providing equipment and free choice of activities; or (4) usual practice. The primary outcomes were lesson time spent in moderate-to-vigorous PA, and motivation towards the lesson. Secondary outcomes were perceptions of teacher behavior, psychological needs satisfaction, and lesson time spent in sedentary behavior. PA and sedentary behavior were measured during baseline and post-intervention lessons with waist-mounted Actigraph GT3X accelerometers. Teacher behavior, psychological needs satisfaction, and motivation were assessed via questionnaires at the end of each lesson. Linear mixed-model analyses will be run on all outcomes, with students nested within teachers as a random effect. Study

To explore the experiences of participants involved in the implementation of the Productive Ward: Releasing Time to Care™ initiative in Ireland, identifying key implementation lessons. A large-scale quality improvement programme Productive Ward: Releasing Time to Care™ was introduced nationwide into Ireland in 2011. We captured accounts from ward-based teams in an implementation phase during 2013-14 to explore their experiences. Semi-structured, in-depth interviews with a purposive sample of 24 members of ward-based teams from nine sites involved in the second national phase of the initiative were conducted. Interviews were analysed and coded under themes, using a seven-stage iterative process. The predominant theme identified was associated with the implementation and management of the initiative and included: project management; training; preparation; information and communication; and participant's negative experiences. The most prominent challenge reported related to other competing clinical priorities. Despite the structured approach of Productive Ward: Releasing Time to Care™, it appears that overstretched and busy clinical environments struggle to provide the right climate and context for ward-based teams to engage and interact actively with quality improvement tools, methods and activities. Findings highlight five key aspects of implementation and management that will help facilitate successful adoption of large-scale, ward-based quality improvement programmes such as Productive Ward: Releasing Time to Care™. Utilising pre-existing implementation or quality frameworks to assess each ward/unit for 'readiness' prior to commencing a quality improvement intervention such as Productive Ward: Releasing Time to Care™ should be considered. © 2017 John Wiley & Sons Ltd.

Final cleanup of buildings within in legacy French research facilities: strategy, tools and lessons learned

International Nuclear Information System (INIS)

2007-01-01

This paper describes the methodology followed by the French Atomic Energy Commission (CEA) to decommission the buildings of former research facilities for demolition or possible reuse. It is a well known fact that the French nuclear safety authority has decided not to define any general release level for the decommissioning of nuclear facilities, thus effectively prohibiting radiological measurement-driven decommissioning. The decommissioning procedure therefore requires an intensive in-depth examination of each nuclear plant. This requires a good knowledge of the past history of the plant, and should be initiated as early as possible. The paper first describes the regulatory framework recently unveiled by the French Safety Authority, then, reviews its application to ongoing decommissioning projects. The cornerstone of the strategy is the definition of waste zoning in the buildings to segregate areas producing conventional waste from those generating nuclear waste. After dismantling, suitable measurements are carried out to confirm the conventional state of the remaining walls. This requires low-level measurement methods providing a suitable detection limit within an acceptable measuring time. Although this generally involves particle counting and in-situ low level gamma spectrometry, the paper focuses on y spectrometry. Finally, the lessons learned from ongoing projects are discussed.

The verification of DRAGON: progress and lessons learned

International Nuclear Information System (INIS)

Marleau, G.

2002-01-01

The general requirements for the verification of the legacy code DRAGON are somewhat different from those used for new codes. For example, the absence of a design manual for DRAGON makes it difficult to confirm that the each part of the code performs as required since these requirements are not explicitly spelled out for most of the DRAGON modules. In fact, this conformance of the code can only be assessed, in most cases, by making sure that the contents of the DRAGON data structures, which correspond to the output generated by a module of the code, contains the adequate information. It is also possible in some cases to use the self-verification options in DRAGON to perform additional verification or to evaluate, using an independent software, the performance of specific functions in the code. Here, we will describe the global verification process that was considered in order to bring DRAGON to an industry standard tool-set (IST) status. We will also discuss some of the lessons we learned in performing this verification and present some of the modification to DRAGON that were implemented as a consequence of this verification.

288 bunches could be injected, during MD time, for both beams with a good margin between the losses and the BLM dump thresholds. Improvements are still needed to optimize the 25 ns beam in the injector chain and accumulate it in the LHC with a good lifetime; the results are encouraging in view of operation with the designed intensity. Machine Protection, M. Zerlauth (TE-MPE): M. Zerlauth introduced the architecture of the LHC Machine Protection System (MPS). He explained that this is a complex system that checks more than 10000 interlock conditions and has to evolve to follow operational changes, special runs and MD requirements. Vacuum Performance and Lessons for 2012, V. Baglin (TE-VSC): V. Baglin presented a talk on the main vacuum observations made in 2011: dynamic effects induced by the circulating beam (synchrotron radiation and e-clouds) and unexpected local pressure spikes. He explained that the desorption yield in the cold-warm transitions was much worse (factor 50) than in the warm-warm transition due to gas load from the cold part. Emittance Preservation, V. Kain (BE-OP): V. Kain spoke about emittance preservation all along the injectors chain up to collisions in the LHC. She explained that injectors behaved extremely well in 2011 and, for the 50 ns beams and a bunch population higher than nominal, an emittance blowup of 0.4 μm was measured from the PS to the SPS (from design report: 0.5 μm were estimated for 25 ns beams). On the other hand a 20-30% emittance growth is observed between the SPS flattop and LHC collisions. Several methods are used for emittance measurements (wire scanner, BSRT and luminosity) and all methods present some limitations. Moreover measurements in the SPS and in the LHC are not synchronized and refer to different beams.

Supernovae and Gamma-Ray bursts display many similarities, both in their observational qualities and in the engines behind these powerful explosions. Although not identical, there is a strong synergy in the study of these two objects. There is much the gamma-ray burst field can learn from the lessons of the more-developed supernova field, but the supernova field can also learn from new techniques developed for gamma-ray burst studies. Here I review some of the 'lessons learned' from these fields to help foster this synergy.

Taenia solium Cysticercosis--The lessons of history.

Science.gov (United States)

Del Brutto, Oscar H; García, Héctor H

2015-12-15

Human taeniasis as well as porcine and human cysticercosis--caused by the pork tapeworm Taenia solium--are ancient diseases. The fact that pigs were considered impure in the ancient Greece and that the Koran prohibited the consumption of pork, were likely related to the knowledge that cysticercosis may affect swine. Evidence suggests that human cysticercosis was also present in the ancient Egypt and Rome. During the Renaissance, the causative agent was properly identified and human cases were recognized. Confirmation that both taeniasis and cysticercosis were caused by the same parasite was provided during the 19th Century by German pathologists. During the 20th Century, bouts of human cysticercosis in non-endemic regions left us valuable lessons on the mechanisms of disease acquisition and spread. These included a large series of neurocysticercosis cases in the United Kingdom that occurred after the return of troops stationed in India (which demonstrated that symptoms may occur years after infection), the epidemic of cysticercosis-related epilepsy in the Ekari people of Papua New Guinea occurring after the gift of pigs with cysticercosis received from Indonesia (demonstrating the fast establishment of endemic transmission and the impact of cysticercosis in epilepsy frequency), and the occurrence of neurocysticercosis among members of an Orthodox Jewish community of New York City, related to Latin American Taenia carriers working in their houses (highlighting the fact that cysticercosis transmission do not require the presence of infected pigs). These lessons of history have significantly contributed to our current knowledge on this disease. Copyright © 2015 Elsevier B.V. All rights reserved.

Lessons learned using Snodgrass hypospadias repair.

LENUS (Irish Health Repository)

O'Connor, K M

2012-02-03

BACKGROUND: This is a review of our experience with the Snodgrass technique for distal hypospadias repair and we point to lessons learned in improving results. METHODS: We reviewed all patients who underwent Snodgrass hypospadias repair for distal hypospadias over a four-year period by a single surgeon. Chart review followed by parental telephone interview was used to determine voiding function, cosmesis and complication rate. RESULTS: Thirty children and three adults were identified. Age at surgery ranged from seven months to 39 years. The urinary stream was straight in 94%, and 97% reported a good or satisfactory final cosmetic outcome. One patient (3.3%) developed a urethral fistula and 21% developed meatal stenosis which required general anaesthetic. CONCLUSION: The Snodgrass urethroplasty provides satisfactory cosmetic and functional results. High rates of meatal stenosis initially encountered have improved with modifications to technique which include modified meatoplasty and routine meatal dilatation by the parents.

Lessons learned implementing environmental regulations at non-Department of Energy sites

1991-01-01

The Hazardous Waste Remedial Actions Program (HAZWRAP) has been involved in the implementation of environmental regulations at non-Department of Energy (DOE) facilities for > 5 years. If any common thread has been identified in working at these sites, it is that no two sites can be treated the same. Each site and its associated wastes, governing regulations, and environmental conditions are different. The list of technical lessons learned is long, and their applicability to other sites must be looked at for each specific case. That is far too large a task to undertake here. The most important lesson HAZWRAP learned is not technical. Implementing environmental regulations at non-DOE sites is not any different from implementing regulations or anything else done at DOE facilities. The key to success lies in quality, planning, and communication. Taking the time to implement a good quality program based on sound planning and open communication will ensure program success

Lens time delays are a powerful probe of cosmology, provided that the gravitational potential of the main deflector can be modeled with sufficient precision. Recent work has shown that this can be achieved by detailed modeling of the host galaxies of lensed quasars, which appear as ''Einstein Rings'' in high resolution images. The distortion of these arcs and counter-arcs, as measured over a large number of pixels, provides tight constraints on the difference between the gravitational potential between the quasar image positions, and thus on cosmology in combination with the measured time delay. We carry out a systematic exploration of the high resolution imaging required to exploit the thousands of lensed quasars that will be discovered by current and upcoming surveys with the next decade. Specifically, we simulate realistic lens systems as imaged by the Hubble Space Telescope (HST), James Webb Space Telescope (JWST), and ground based adaptive optics images taken with Keck or the Thirty Meter Telescope (TMT). We compare the performance of these pointed observations with that of images taken by the Euclid (VIS), Wide-Field Infrared Survey Telescope (WFIRST) and Large Synoptic Survey Telescope (LSST) surveys. We use as our metric the precision with which the slope γ' of the total mass density profile ρ{sub tot}∝ r{sup −γ'} for the main deflector can be measured. Ideally, we require that the statistical error on γ' be less than 0.02, such that it is subdominant to other sources of random and systematic uncertainties. We find that survey data will likely have sufficient depth and resolution to meet the target only for the brighter gravitational lens systems, comparable to those discovered by the SDSS survey. For fainter systems, that will be discovered by current and future surveys, targeted follow-up will be required. However, the exposure time required with upcoming facilitites such as JWST, the Keck Next Generation

Four accidents involving the approach to criticality occurred during the period July, 1945, through May, 1996. These have been described in the format of the OPERATING EXPERIENCE WEEKLY SUMMARY which is distributed by the Office of Nuclear and Facility Safety. Although the lessons learned have been incorporated in standards, codes, and formal procedures during the last fifty years, this is their first presentation in this format. It is particularly appropriate that they be presented in the forum of the Nuclear Criticality Technology Safety Project Workshop closest to the fiftieth anniversary of the last of the four accidents, and that which was most instrumental in demonstrating the need to incorporate lessons learned

2018-04-24

The worlds of a physician and a jazz musician seem entirely different. Various studies, however, relating the concepts behind jazz music to medical practice and education, have been published. The aim of this essayistic review is to summarize previously described concepts behind jazz music and its required artistic skills that could be translated to medicine, encouraging doctors, medical students and medical educators to see their professional environment from a different perspective. A systematic search was conducted using PubMed, Embase, and ERIC databases, combining keywords with regard to jazz, medicine and medical education. Background information concerning jazz music and several jazz musicians was retrieved through an additional nonsystematic search using Google Scholar. Lessons with regard to improvisational skills, both in communication with patients and in a technical context, communication skills, leadership, interprofessional teamwork and coping with errors are presented. Doctors and medical students could learn various lessons from jazz music performance and jazz musicians. The potential and the possibilities of implementing jazz into the medical curriculum, in order to contribute to the development of professional skills and attitudes of medical students, could be explored further.

Evidence for the effectiveness of Alexander Technique lessons in medical and health-related conditions: a systematic review.

Woodman, J P; Moore, N R

2012-01-01

Complementary medicine and alternative approaches to chronic and intractable health conditions are increasingly being used, and require critical evaluation. The aim of this review was to systematically evaluate available evidence for the effectiveness and safety of instruction in the Alexander Technique in health-related conditions. PUBMED, EMBASE, PSYCHINFO, ISI Web-of-Knowledge, AMED, CINHAL-plus, Cochrane library and Evidence-based Medicine Reviews were searched to July 2011. Inclusion criteria were prospective studies evaluating Alexander Technique instruction (individual lessons or group delivery) as an intervention for any medical indication/health-related condition. Studies were categorised and data extracted on study population, randomisation method, nature of intervention and control, practitioner characteristics, validity and reliability of outcome measures, completeness of follow-up and statistical analyses.   Of 271 publications identified, 18 were selected: three randomised, controlled trials (RCTs), two controlled non-randomised studies, eight non-controlled studies, four qualitative analyses and one health economic analysis. One well-designed, well-conducted RCT demonstrated that, compared with usual GP care, Alexander Technique lessons led to significant long-term reductions in back pain and incapacity caused by chronic back pain. The results were broadly supported by a smaller, earlier RCT in chronic back pain. The third RCT, a small, well-designed, well-conducted study in individuals with Parkinson's disease, showed a sustained increased ability to carry out everyday activities following Alexander lessons, compared with usual care. The 15 non-RCT studies are also reviewed. Strong evidence exists for the effectiveness of Alexander Technique lessons for chronic back pain and moderate evidence in Parkinson's-associated disability. Preliminary evidence suggests that Alexander Technique lessons may lead to improvements in balance skills in the

Lesson from a 60Co source radiation accident

2002-01-01

A serious radiation accident happened an a 60 Co irradiation facility in Shanghai. 7 workers were uniformly exposed acutely. An investigation was done after the accident and a conclusion was achieved that the irregular operation was the direct reason for the accident. The operation of these workers did not comply with the requirements specified in the national standards-- 60 irradiation facility>> which demands that the examination should be done every day before operation, and the irradiation facility does not stop running when the auto-lock safety system on that facility has been removed. Some lessons should be drawn from the accident: popularizing the culture of safety, enhancing the law of safety, and ensuring the operation of radiation devices within the demands of safety

Administrative health data in Canada: lessons from history.

Health decision-making requires evidence from high-quality data. As one example, the Discharge Abstract Database (DAD) compiles data from the majority of Canadian hospitals to form one of the most comprehensive and highly regarded administrative health databases available for health research, internationally. However, despite the success of this and other administrative health data resources, little is known about their history or the factors that have led to their success. The purpose of this paper is to provide an historical overview of Canadian administrative health data for health research to contribute to the institutional memory of this field. We conducted a qualitative content analysis of approximately 20 key sources to construct an historical narrative of administrative health data in Canada. Specifically, we searched for content related to key events, individuals, challenges, and successes in this field over time. In Canada, administrative health data for health research has developed in tangent with provincial research centres. Interestingly, the lessons learned from this history align with the original recommendations of the 1964 Royal Commission on Health Services: (1) standardization, and (2) centralization of data resources, that is (3) facilitated through governmental financial support. The overview history provided here illustrates the need for longstanding partnerships between government and academia, for classification, terminology and standardization are time-consuming and ever-evolving processes. This paper will be of interest to those who work with administrative health data, and also for countries that are looking to build or improve upon their use of administrative health data for decision-making.

Digital control for nuclear reactors - lessons learned

Bernard, J.A.; Aviles, B.N.; Lanning, D.D.

1992-01-01

Lessons learned during the course of the now decade-old MIT program on the digital control of nuclear reactors are enumerated. Relative to controller structure, these include the importance of a separate safety system, the need for signal validation, the role of supervisory algorithms, the significance of command validation, and the relevance of automated reasoning. Relative to controller implementation, these include the value of nodal methods to the creation of real-time reactor physics and thermal hydraulic models, the advantages to be gained from the use of real-time system models, and the importance of a multi-tiered structure to the simultaneous achievement of supervisory, global, and local control. Block diagrams are presented of proposed controllers and selected experimental and simulation-study results are shown. In addition, a history is given of the MIT program on reactor digital control

Lessons on collisionless reconnection from quantum fluids

Directory of Open Access Journals (Sweden)

Yasuhito eNarita

2014-12-01

Full Text Available Magnetic reconnection in space plasmas remains a challenge in physics in that the phenomenon is associated with the breakdown of frozen-in magnetic field in a collisionless medium. Such a topology change can also be found in superfluidity, known as the quantum vortex reconnection. We give a plasma physicists' view of superfluidity to obtain insights on essential processes in collisionless reconnection, including discussion of the kinetic and fluid pictures, wave dynamics, and time reversal asymmetry. The most important lesson from the quantum fluid is the scenario that reconnection is controlled by the physics of topological defects on the microscopic scale, and by the physics of turbulence on the macroscopic scale. Quantum vortex reconnection is accompanied by wave emission in the form of Kelvin waves and sound waves, which imprints the time reversal asymmetry.

Full Text Available In the information era that we experience today, there is a rapid change in the methods, techniques and materials used for education and teaching. The usage of information and communication technology-assisted teaching materials are becoming more commonplace. Parallel to these developments, the Ministry of National Education took steps to develop IT substructures of all schools in the country and implemented many projects. The purpose of this study is to determine whether or not the multimedia lesson content used by teachers affect effective learning. This study is a qualitative study, conducted with 45 teachers working in primary schools during the 2011-2012 academic year. According to the study findings, participants believe that using multimedia lesson content during lectures increases student motivation, makes students more curious and interested, and think that using multimedia lesson content has positive effects.

Design Requirements for Communication-Intensive Interactive Applications

Science.gov (United States)

Bolchini, Davide; Garzotto, Franca; Paolini, Paolo

Online interactive applications call for new requirements paradigms to capture the growing complexity of computer-mediated communication. Crafting successful interactive applications (such as websites and multimedia) involves modeling the requirements for the user experience, including those leading to content design, usable information architecture and interaction, in profound coordination with the communication goals of all stakeholders involved, ranging from persuasion to social engagement, to call for action. To face this grand challenge, we propose a methodology for modeling communication requirements and provide a set of operational conceptual tools to be used in complex projects with multiple stakeholders. Through examples from real-life projects and lessons-learned from direct experience, we draw on the concepts of brand, value, communication goals, information and persuasion requirements to systematically guide analysts to master the multifaceted connections of these elements as drivers to inform successful communication designs.

Full Text Available The purpose of the present study was to compare the effects of two different teaching methods on students' comprehension during Physical Education lesson: narration versus animation with concurrent narration, during teaching shot put event. Thirty primary school children (boys and girls volunteered to participate in this study. In experiment students listened (narration and viewed (animation with narration the presentation of two shot putting styles. A problem-solving and a retention test were used to evaluate students' comprehension. Results showed that students' comprehension was better when shot putting styles were presented through a mixed model (animation and narration group than a single (narration. The animation with concurrent narration group performed better than the narration group, in problem-solving (M = 4.91, SD = 1.36 and in retention test (M = 5.98, SD = 1.28 t(28 = 1.89 p<0.01. An instructional implication is that pictures with words is more effective way of teaching when they occur continuingly in time, than only words during Physical Education lesson.

2017-03-01

Full Text Available Lesson planning is at the core of teaching. It allows teachers to create an orientation path in the process of teaching, taking into consideration, many elements such as, students’ styles of learning, previous knowledge, types of intelligences, interests etc. Effective curricula plans are characterized by principles of coherence, flexibility, integration of knowledge etc. Effective lesson plans strongly rely on previous information gathered through different forms of assessment, and provide inclusive opportunities for every student. This paper will show how planning affects teaching and the quality of learning. First, a review of the literature will represent the importance of flexible planning and incorporation of differentiated elements of planning that ensure inclusive opportunities of learning for all students. Second, there will be a detailed analysis of findings taken by 25 full school inspections practices on the field of “lesson planning”. This part of the study will specify the planning difficulties the teachers face and how this affects the process of teaching and learning. Third, benefits of lesson plans that rely on good assessment practices and integrate differentiated instruction according to students' needs will be discussed as ways of helping teachers adjust lesson plans to overcome their planning difficulties. Findings indicate that teachers design lesson plans that do not rely on good assessment practices. Lesson plans are not flexible enough to respond and satisfy the needs of all categories of students, impacting that way the quality of instruction and learning. The paper will serve teachers to review their planning approaches and integrate elements of differentiated instruction as an organic part of the process, responding to traits and uniqueness students represent.

Abstract Realistic planning for a nutrition intervention is a critical component of implementation, yet effective approaches have been poorly documented. Under the auspices of “The Micronutrient Powders Consultation: Lessons Learned for Operational Guidance,” 3 working groups were formed to summarize experiences and lessons across countries regarding micronutrient powders (MNP) interventions for young children. This paper focuses on programmatic experiences in the planning stages of an MNP intervention, encompassing assessment, enabling environment and adaptation, as well as considerations for supply. Methods included a review of published and grey literature, key informant interviews, and deliberations throughout the consultation process. We found that assessments helped justify adopting an MNP intervention, but these assessments were often limited by their narrow scope and inadequate data. Establishing coordinating bodies and integrating MNP into existing policies and programmes have helped foster an enabling environment and support programme stability. Formative research and pilots have been used to adapt MNP interventions to specific contexts, but they have been insufficient to inform scale‐up. In terms of supply, most countries have opted to procure MNP through international suppliers, but this still requires understanding and navigating the local regulatory environment at the earliest stages of an intervention. Overall, these findings indicate that although some key planning and supply activities are generally undertaken, improvements are needed to plan for effective scale‐up. Much still needs to be learned on MNP planning, and we propose a set of research questions that require further investigation. PMID:28960875

Full text: Real time computer systems are increasingly used for safety critical supervision and control of nuclear reactors. Typical application areas are supervision of reactor core against coolant flow blockage, supervision of clad hot spot, supervision of undesirable power excursion, power control and control logic for fuel handling systems. The most frequent cause of fault in safety critical real time computer system is traced to fuzziness in requirement specification. To ensure the specified safety, it is necessary to model the requirement specification of safety critical real time computer systems using formal mathematical methods. Modeling eliminates the fuzziness in the requirement specification and also helps to prepare the verification and validation schemes. Test data can be easily designed from the model of the requirement specification. Z and B are the popular languages used for modeling the requirement specification. A typical safety critical real time computer system for supervising the reactor core of prototype fast breeder reactor (PFBR) against flow blockage is taken as case study. Modeling techniques and the actual model are explained in detail. The advantages of modeling for ensuring the safety are summarized

Supply chain management/ Some lessons learned the hard way.

Nuttall, Stephen

2013-01-01

This paper will look at some of the experiences, lessons and frustrations experienced in managing supply chains for business continuity. No-one has time to make all the mistakes, nor to learn all the lessons on their own, so it is useful to share experiences. Over the last 25 years, the author has been involved in supply chain management as a contract manager; a programme and project manager; and as a business continuity manager. Although times change, there are some fundamental principles that are absolutely critical in making sure that supply chains do what they are needed to do/ to keep business going. Supply chains are here to stay. Indeed, with today's drive towards outsourcing, best-shoring and contracting out, they are becoming more important every year and this will only continue over time. Moreover, in the highly competitive markets in which all organisations operate, suppliers may well be carrying out operations that not all that long ago would have been considered to be part of core business. Getting the right relationship with the supply chain is more critical than ever before.1 What does this mean to business continuity professionals? They need to think not just about their own BC plans, but about the plans of their suppliers, and even those of their suppliers' suppliers. This may seem obvious, but unlike internal BC plans written by and for an organisation, it must be considered just what a supplier's plans are designed to achieve. What business outcomes will their plans deliver? If they recover their own business, how does that affect the business they serve? Are others' assumptions of how they will react in line with theirs?

Physical exercise confers many health benefits, but it is difficult to motivate people to exercise. Although community exercise groups may facilitate initiation and persistence in an exercise program, reports regarding factors that allow such groups to flourish are limited. We performed a prospective qualitative evaluation of our experience starting a program of community-based, peer-led exercise groups for military veterans to identify important lessons learned. We synthesized data from structured observations, post-observation debriefings, and focus groups. Our participants were trained peer leaders and exercise group members. Our main outcomes consisted of empirically derived lessons learned during the implementation of a peer-led group exercise program for veterans at multiple community sites. We collected and analyzed data from 40 observation visits (covering 14 sites), 7 transcribed debriefings, and 5 focus groups. We identified five lessons learned. (1) The camaraderie and social aspect of the exercise groups provided motivation for people to stay involved. (2) Shared responsibility and commitment to each other by the group members was instrumental to success. (3) Regular meeting times encouraged participation. (4) Variety, especially getting outdoors, was very popular for some groups. (5) Modest involvement of professionals encouraged ongoing engagement with the program. Both social and programmatic issues influence implementation of group exercise programs for older, predominantly male, veterans. These results should be confirmed in other settings.

Teachers' Perceptions of Infusion of Values in Science Lessons: a Qualitative Study

Kumarassamy, Jayanthy; Koh, Caroline

2017-06-01

Much has been written and debated on the importance of including moral, character or values education in school curricula. In line with this, teachers' views with regard to values education have often been sought. However, a search into the literature on values in science education has revealed little on this domain. In an attempt to close this gap, this study explored the views of teachers with regard to values infusion in the teaching of science. The aim was to investigate teachers' perceptions on two broad areas: (i) how values were infused or addressed in lower secondary science and (ii) how values-infused science lessons influenced their students' dispositions and actions. The participants who took part in the interviews were lower secondary science teachers teaching Grade 8 in selected Singapore and New Delhi schools. The findings showed that values inherent in the discipline of science, such as validity, fairness, honesty, rigour, predominated in the lessons conducted by the teachers in both contexts. Furthermore, in Singapore, equal numbers of teachers made references to values upheld and practised by scientists and values arising from the interplay between people and scientific processes and products. In New Delhi however, the emphasis was higher on the latter category of values than on the former. Generally, in both contexts, values infusion in science lessons was not planned but occurred spontaneously as values issues surfaced in class. Teachers in both Singapore and New Delhi used strategies such as questioning, discussion, activities and direct instructions to carry out values infusion, although they experienced challenges that included content and time constraints, lack of student readiness and of teacher competency. Nevertheless, the teachers interviewed perceived that values in science lessons brought about changes in students' personal attributes, affect and behaviour, such as greater interest and prosocial engagement.

Full Text Available Aim: It is aimed to determine the attitudes of the 2nd, 3rd, and 4th grade classroom teacher candidates towards the physical education lesson according to various variables. Material and Methods: For the current study, the screening method, one of the quantitative research models, was used. The research consists of 2nd, 3rd, and 4th grade, totally164 university students, 106 (%64,6 females, 58 (%35,4 males, attending Uşak University, Classroom Teaching Program in 2016-2017 academic year. The first-grade students were not included in this research, because the physical education and play teaching lessons are given to classroom student candidates in the second-grade at Uşak University, Classroom Teaching Program. “Personal information form" and “Physical Education Lesson Attitude Scale for Classroom Teacher Candidates" were used as data collection tools. Before analysis, the data were evaluated using the values of Skewness and Skewness (normal distribution of the data and Levene (equality of variance tests. In the analysis of the data; frequency, arithmetic mean, standard deviation; t-test, ANOVA and Pearson Correlation test were used. Results: When examined the total score of the teacher candidates obtained from Physical Education Lesson Attitude Scale for Classroom Teacher Candidates and age variable by the Pearson Moment Correlation analysis, it was found that there was a statistically significant negative relationship between the received scores at low level. It was determined that the attitudes of the classroom teacher candidates towards the physical education lessons did not show any significant difference according to the gender variable, but there was a significant difference when examined their class levels. While no significant difference was found in the attitudes of the classroom teacher candidates, who played and did not play sports in their past life, towards physical education lessons, no significant difference was found

Various organizations have suggested that physical education (PE) should play a central role in increasing adolescents' physical activity (PA) levels. The purpose of this study was to examine relationships between students' self-determined motivation and their PA behavior during a structured PE lesson led by their teacher and a free-choice period in which they were not required to be active. 528 Hong Kong students (mean age=15.78 years) participated in this study in April and May 2007. Situational Motivation Scale scores were used to form high and low self-determined motivation groups. Students wore a pedometer during a 20-minute structured basketball lesson and a 20-minute free choice period, during which they did not receive instruction. ANOVA revealed that self-determined motivation and PE class environments which provided students opportunities to make choices were related to greater PA. Furthermore, the difference in PA between the high and low self-determined groups was greater in the free-choice condition than the structured lesson, suggesting that self-determined motivation is especially important when students are not supervised. Findings indicated that promoting self-determined motivation may be an effective means of ensuring that PE programs are able to increase PA levels, foster self-initiated PA behaviors, and enhance adolescents' health.

To determine the effectiveness of lessons in the Alexander technique, massage therapy, and advice from a doctor to take exercise (exercise prescription) along with nurse delivered behavioural counselling for patients with chronic or recurrent back pain. Factorial randomised trial. 64 general practices in England. 579 patients with chronic or recurrent low back pain; 144 were randomised to normal care, 147 to massage, 144 to six Alexander technique lessons, and 144 to 24 Alexander technique lessons; half of each of these groups were randomised to exercise prescription. Normal care (control), six sessions of massage, six or 24 lessons on the Alexander technique, and prescription for exercise from a doctor with nurse delivered behavioural counselling. Roland Morris disability score (number of activities impaired by pain) and number of days in pain. Exercise and lessons in the Alexander technique, but not massage, remained effective at one year (compared with control Roland disability score 8.1: massage -0.58, 95% confidence interval -1.94 to 0.77, six lessons -1.40, -2.77 to -0.03, 24 lessons -3.4, -4.76 to -2.03, and exercise -1.29, -2.25 to -0.34). Exercise after six lessons achieved 72% of the effect of 24 lessons alone (Roland disability score -2.98 and -4.14, respectively). Number of days with back pain in the past four weeks was lower after lessons (compared with control median 21 days: 24 lessons -18, six lessons -10, massage -7) and quality of life improved significantly. No significant harms were reported. One to one lessons in the Alexander technique from registered teachers have long term benefits for patients with chronic back pain. Six lessons followed by exercise prescription were nearly as effective as 24 lessons. National Research Register N0028108728.

The contribution includes the lessons learned within frame of the radiological characterisation of surface ground layer in the NPP A1 site of area approximately 60 m2 (9 x 7 m) that was a part of Controlled area. Aim of the characterisation was a demonstration that the area fulfils the requirements to exemption from Controlled area for purpose of decommissioning activities carry out within frame of II. stage of NPP A1 decommissioning project.The requirements on free release of materials into the environment were applied (e.g. 300 Bq/kg for single 137 Cs). Radiological characterisation was performed by two independent methods; in situ scintillation gamma spectrometry and systematic sampling in regular grid followed by gamma spectrometry analyses in accredited laboratory of VUJE, Inc. (S-219). This improved the quality of monitoring and at the same time it enabled the inter-comparison of results obtained by both mentioned independent methods.Characterised ground area was partitioned to smaller sub-areas of 4 m2. At ground layer of 20 cm it means approximately 1000 kg of ground (in compliance with requirements on reference area at even activity distribution according to government regulation No 345/2006) The results of measurements showed that under appropriate conditions (sufficiently low radiation background, on interfering external sources) also the designed in situ method is effective and reliable tool for contaminated ground layer identification. In addition the in situ method is more effective in terms of time and cost consumption on unit of monitored area. (authors)

The Waste Isolation Pilot Plant (WIPP) Compliance Certification Application (CCA) Performance Assessment (PA) used a relational database that was originally designed only to supply the input parameters required for implementation of the PA codes. Reviewers used the database as a point of entry to audit quality assurance measures for control, traceability, and retrievability of input information used for analysis, and output/work products. During these audits it became apparent that modifications to the architecture and scope of the database would benefit the EPA regulator and other stakeholders when reviewing the recertification application.

Lessons learned about slope stability in the course of four decades of monitoring, and in some cases stabilizing, slopes along British Columbia's hydroelectric reservoirs are discussed. The lessons are illustrated by short case histories of some of the more important slopes such as Little Chief Slide, Dutchman's Ridge, Downie Slide, Checkerboard Creek and Wahleach. Information derived from the monitoring and other investigations are compared with early interpretations of geology and slope performance. The comparison serves as an indicator of progress in slope stability determination and as a measure of the value of accumulated experience in terms of the potential consequences to safety and cost savings over the long life-span of hydroelectric projects.14 refs., 2 tabs., 15 figs

Learning from Iraq and Afghanistan: Four Lessons for Building More Effective Coalitions

Directory of Open Access Journals (Sweden)

White Nathan

2016-06-01

Full Text Available Despite many tactical and operational successes by brave military and civilian personnel, post-9/11 operations by U.S. led coalitions in Iraq and Afghanistan did not achieve their intended outcomes. Although many efforts are underway by discrete organizations within coalition countries to identify and learn their own lessons from these conflicts, comparatively less attention is paid to broader lessons for successful coalitions. Given that the U.S. and its allies will most certainly form coalitions in the future for a range of different contingency scenarios, these lessons are equally deserving of close examination. This article identifies four interrelated lessons from Iraq and Afghanistan that can be utilized to inform more effective coalition development and employment.

Bridging the Gap - Networking Educators using Real-Time Seismic Data

2004-12-01

After nearly a decade, the seismology community has made critical advances in identifying what is effective and what is needed for success in incorporating real-time seismic data in the classroom. Today's K-16 classroom teachers have many options and opportunities for incorporating short- and long-term inquiry activities for monitoring earthquakes and analyzing seismic data in their daily instruction. Through the SpiNet program, we are providing web-based tools that support educators working with real-time seismic data (http://www.scieds.com/spinet/). Our site includes a Recent Seismicity section, which allows users to share seismic data in real-time, and provides near real-time information about global seismicity. Our Activities section provides data and lessons to assist educators who wish to integrate seismology into their classroom. The Research section, currently under development, will allow educators to share general information about how they teach seismology in their classroom through a discussion board and by posting lesson plans. In addition, we are developing a user-friendly tool for students to post results of their research projects. Designing a website which targets a range of users requires a working knowledge of both user needs and website programming and design. User needs include providing a logical navigational structure and accounting for differences in browser functionality, internet access, and users' abilities. Using website development tools, such as PHP, MySQL, RDF feeds, and specialized geoscience applications, we are automating site maintenance; incorporating databases for information storage and retrieval; and providing accessibility for users with a range of skills and physical limitations. By incorporating these features, we have built a dynamic interface for a broad range of users interested in educational seismology.

Rabies is an important neglected disease, which kills around 59,000 people a year. Over a third of these deaths are in children less than 15 years of age. Almost all human rabies deaths in Africa and Asia are due to bites from infected dogs. Despite the high efficacy of current rabies vaccines, awareness about rabies preventive healthcare is often low in endemic areas. It is therefore common for educational initiatives to be conducted in conjunction with other rabies control activities such as mass dog vaccination, however there are few examples where the efficacy of education activities has been assessed. Here, primary school children in Zomba, Malawi, were given a lesson on rabies biology and preventive healthcare. Subsequently, a mass dog vaccination programme was delivered in the same region. Knowledge and attitudes towards rabies were assessed by a questionnaire before the lesson, immediately after the lesson and 9 weeks later to assess the impact the lesson had on school children's knowledge and attitudes. This assessment was also undertaken in children who were exposed to the mass dog vaccination programme but did not receive the lesson. Knowledge of rabies and how to be safe around dogs increased following the lesson (both prabies and how to be safe around dogs was greater amongst school children who had received the lesson compared to school children who had not received the lesson, but had been exposed to a rabies vaccination campaign in their community (both prabies can improve short and medium-term rabies knowledge and attitudes of Malawian schoolchildren.

Learning lessons from Natech accidents - the eNATECH accident database

Science.gov (United States)

Krausmann, Elisabeth; Girgin, Serkan

2016-04-01

When natural hazards impact industrial facilities that house or process hazardous materials, fires, explosions and toxic releases can occur. This type of accident is commonly referred to as Natech accident. In order to prevent the recurrence of accidents or to better mitigate their consequences, lessons-learned type studies using available accident data are usually carried out. Through post-accident analysis, conclusions can be drawn on the most common damage and failure modes and hazmat release paths, particularly vulnerable storage and process equipment, and the hazardous materials most commonly involved in these types of accidents. These analyses also lend themselves to identifying technical and organisational risk-reduction measures that require improvement or are missing. Industrial accident databases are commonly used for retrieving sets of Natech accident case histories for further analysis. These databases contain accident data from the open literature, government authorities or in-company sources. The quality of reported information is not uniform and exhibits different levels of detail and accuracy. This is due to the difficulty of finding qualified information sources, especially in situations where accident reporting by the industry or by authorities is not compulsory, e.g. when spill quantities are below the reporting threshold. Data collection has then to rely on voluntary record keeping often by non-experts. The level of detail is particularly non-uniform for Natech accident data depending on whether the consequences of the Natech event were major or minor, and whether comprehensive information was available for reporting. In addition to the reporting bias towards high-consequence events, industrial accident databases frequently lack information on the severity of the triggering natural hazard, as well as on failure modes that led to the hazmat release. This makes it difficult to reconstruct the dynamics of the accident and renders the development of

Full Text Available The methodology of system requirements verification presented in this paper is a proposition of a practical procedure for reducing some negatives of the specification of requirements. The main problem that is considered is to create a complete description of the system requirements without any negatives. Verification of the initially defined requirements is based on the coloured Petri nets. Those nets are useful for testing some properties of system requirements such as completeness, consistency and optimality. An example ofthe litt controller is presented.

Neilson, G.H.; Gruber, C.O.; Harris, Jeffrey H.; Rej, D.J.; Simmons, R.T.; Strykowsky, R.L.

2010-01-01

The National Compact Stellarator Experiment (NCSX) was designed to test physics principles of an innovative stellarator design developed by Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory. Construction of some of the major components and subassemblies 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, which was 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 2007-2008. It led to a better understanding of project risks, a sounder basis for contingency estimates, and improved management tools. Although the risks were ultimately unacceptable to the sponsor, valuable lessons in risk management were learned through the experiences with the NCSX project.

2005-01-01

The sarin gas attack in the Tokyo subway system is reviewed from a clinical toxicology perspective. Based on the lessons learned from this attack, the following areas should be addressed on a global scale. First, an adequate supply of protective equipment is required, including level B protective equipment with a pressure demand breathing apparatus. In addition, a system should be established that enables a possible cause to be determined based on symptoms, physical findings, general laboratory tests, and a simple qualitative analysis for poisonous substances. If an antidote is needed, the system should enable it to be administered to the victims as quickly as possible. Preparation for a large-scale chemical attack by terrorists requires the prior establishment of a detailed decontamination plan that utilizes not only mass decontamination facilities but also public facilities in the area. A system should be established for summarizing, evaluating, and disseminating information on poisonous substances. Finally, a large-scale scientific investigation of the Tokyo sarin attack should be conducted to examine its long-term and subclinical effects and the effects of exposure to asymptomatic low levels of sarin

Serbian SNF Repatriation Operation. Issues, Solving, Lesson

Energy Technology Data Exchange (ETDEWEB)

Smirnov, A. [Research and Development Company ' Sosny' , Moscow (Russian Federation)

2011-07-01

For now the removal of SNF from RA reactor site (PC NFS, Serbia) is the most time-consuming and technically complicated operation under RRRFR Program. The most efficient techniques and lessons learned from other projects of the RRRFR Program as well as new unique technical decisions were used. Two big challenges were resolved during implementation of Serbian Project: (1) preparation of damaged fuel located in the packages unsuitable for transport, taking into account insufficient infrastructure of RA reactor site and (2) removal of large amount of fuel in one multimodal shipment through several transit countries. The main attention was paid to safety justification of all activities. All approvals were obtained in Russia, Serbia and transit countries. Special canisters were designed for transportation of specific RA reactor fuel (of small dimensions, unidentifiable, damaged due to corrosion). The canister design was selected to be untight - it was the most expedient decision for that case from safety perspective. The technology and a set of equipment were designed for remote removal of the fuel from the existing package (aluminum barrels and reactor channels) and placing of the fuel into the new canisters. After fabrication and assembling of the equipment theoretical and practical training of the personnel was performed. Fuel repackaging took about 5 months. SNF was transported in TUK-19 and SKODA VPVR/M casks. The baskets of large capacity were designed and fabricated for SKODA VPVR/M casks. Special requirements to drying the packages and composition of gaseous medium inside were justified to ensure fire and explosion safety. Specialized ISO-containers and transfer equipment designed under Romanian Project were used together with TUK-19 casks. A forklift and mobile rail system were used to handle SKODA VPVR/M casks under conditions of low capacity of the cranes at the facility. Due to the tight schedule of RRRFR Program as well as geographical peculiarities of RA

Knöös, T

2017-09-01

The purpose of this report is to review and compile what have been and can be learnt from incidents and accidents in radiation oncology, especially in external beam and brachytherapy. Some major accidents from the last 20 years will be discussed. The relationship between major events and minor or so-called near misses is mentioned, leading to the next topic of exploring the knowledge hidden among them. The main lessons learnt from the discussion here and elsewhere are that a well-functioning and safe radiotherapy department should help staff to work with awareness and alertness and that documentation and procedures should be in place and known by everyone. It also requires that trained and educated staff with the required competences are in place and, finally, functions and responsibilities are defined and well known.

Sharing Lessons Learned Between Industries in EU

International Nuclear Information System (INIS)

Muehleisen, A.; Strucic, M.

2012-01-01

Recent events in nuclear industry remind us on importance of continuous sharing of the knowledge and experience gained through evaluations of incidents and accidents. We frequently use experience from our daily life activities to improve our performance and avoid some mistakes or unwanted events. In the similar way we can use other industries experience. These experiences can be applied to improve nuclear safety. For example, Safety Culture, which has a great influence on the level of nuclear power plants safety, is similarly presented in other industries. Mechanisms which led to accidents from weak safety culture in one branch of other industry could be comparable to those in nuclear industry. Some other industries have many more cumulative years of experience than nuclear industry. Aviation and Oil industries are typical representatives. Part of their experience can be used in nuclear industry too. Number of reports from nuclear power plants showed us that not only specific equipment related causes lay behind accidents; there are also other causes and contributors which are more common for all industries. Hence lessons learned in other industry should be assessed and used in nuclear industry too. In the European Union, a regional initiative has been set up in 2008 in support of EU Member State nuclear safety authorities, but also EU technical support organizations, international organizations and the broader nuclear community, to enhance nuclear safety through improvement of the use of lessons learned from operational experience of nuclear power plants (NPPs). The initiative, called ''the EU Clearinghouse on Operational Experience Feedback for NPP'', is organized as a network operated by a centralized office located at the Joint Research Centre of the European Commission. The reduction of occurrence and significance of events in NPPs and their safe operation is its ultimate goal. Among others EU Clearinghouse provides services such as technical and scientific

2001-01-01

John C. Stennis Space Center continues to support the Propulsion community in an effort to validate High-Test Peroxide as an alternative to existing/future oxidizers. This continued volume of peroxide test/handling activity at Stennis Space Center (SSC) provides numerous opportunities for the SSC team to build upon previously documented 'lessons learned'. SSC shall continue to strive to document their experience and findings as H2O2 issues surface. This paper is intended to capture all significant peroxide issues that we have learned over the last three years. This data (lessons learned) has been formulated from practical handling, usage, storage, operations, and initial development/design of our systems/facility viewpoint. The paper is intended to be an information type tool and limited in technical rational; therefore, presenting the peroxide community with some issues to think about as the continued interest in peroxide evolves and more facilities/hardware are built. These lessons learned are intended to assist industry in mitigating problems and identifying potential pitfalls when dealing with the requirements for handling high-test peroxide.

Case Study of Lessons Learned from the Operation of the Fast Flux Test Facility

International Nuclear Information System (INIS)

Wootan, D.; Omberg, R.; Grandy, C.

2016-01-01

Full text: The lessons learned approach being followed at the Fast Flux Test Facility is to have domain experts in each subject area develop a short write-up or report on each lesson learned. Each lesson learned write-up is on the order of 4–6 pages. Longer reports can be developed as needed. Each lessons learned summary discusses the problem and the resolution method employed to address the problem, and also tries to capture the essential “tacit knowledge” associated with each topic in a focused manner. All lessons learned write-ups are supported by more detailed documents. For example, references of more detailed reports are generally included, where available. Topics are selected as those most likely to apply to future design or operating problems. This lessons learned approach has been successful in capturing essential tacit knowledge about key events in FFTF history and providing a context for interpreting the existing data and references.

Post-earthquake building safety inspection: Lessons from the Canterbury, New Zealand, earthquakes

Science.gov (United States)

Marshall, J.; Jaiswal, Kishor; Gould, N.; Turner, F.; Lizundia, B.; Barnes, J.

2013-01-01

The authors discuss some of the unique aspects and lessons of the New Zealand post-earthquake building safety inspection program that was implemented following the Canterbury earthquake sequence of 2010–2011. The post-event safety assessment program was one of the largest and longest programs undertaken in recent times anywhere in the world. The effort engaged hundreds of engineering professionals throughout the country, and also sought expertise from outside, to perform post-earthquake structural safety inspections of more than 100,000 buildings in the city of Christchurch and the surrounding suburbs. While the building safety inspection procedure implemented was analogous to the ATC 20 program in the United States, many modifications were proposed and implemented in order to assess the large number of buildings that were subjected to strong and variable shaking during a period of two years. This note discusses some of the key aspects of the post-earthquake building safety inspection program and summarizes important lessons that can improve future earthquake response.

In May 2007, the Department of Energy and the Fluor Hanford K Basin Closure Project completed transferring sludge from the K East Basin to new containers in the K West Basin using a Hose-in-Hose system. This project presented a number of complex and unique technical, operational, and management challenges that had to be resolved to complete the required transfers and satisfy project milestones. The project team (including DOE; regulators; and Fluor management, operations, maintenance, engineering and all other support organizations) found innovative solutions to each challenge. This paper records lessons learned during the operational phase of the sludge transfer via the Hose-In-Hose system. The subject is limited to the operational phase and does not cover design, development, testing or turnover. A discussion of the situation or problem encountered is provided, along with the lesson learned as applicable to a future program or project

Alzheimer's Disease: Lessons Learned from Amyloidocentric Clinical Trials.

Soejitno, Andreas; Tjan, Anastasia; Purwata, Thomas Eko

2015-06-01

Alzheimer's disease (AD) is one of the most debilitating neurodegenerative diseases and is predicted to affect 1 in 85 people by 2050. Despite much effort to discover a therapeutic strategy to prevent progression or to cure AD, to date no effective disease-modifying agent is available that can prevent, halt, or reverse the cognitive and functional decline of patients with AD. Several underlying etiologies to this failure are proposed. First, accumulating evidence from past trials suggests a preventive as opposed to therapeutic paradigm, and the precise temporal and mechanistic relationship of β-amyloid (Aβ) and tau protein should be elucidated to confirm this hypothesis. Second, we are in urgent need of revised diagnostic criteria to support future trials. Third, various technical and methodological improvements are required, based on the lessons learned from previous failed trials.

On March 11 2011, Tohoku Region Pacific Coast Earthquake hit Japan and caused the devastating damage. The Fukushima Nuclear Power Station (NPS) was also severely damaged.The Japanese NPSs are designed based on the detailed safety requirements and have multiple-folds of hazard controls to the catastrophic hazards as in space system. However, according to the initial information from the Tokyo Electric Power Company (TEPCO) and the Japanese government, the larger-than-expected tsunami and subsequent events lost the all hazard controls to the release of radioactive materials.At the 5th IAASS, Lessons Learned from this disaster was reported [1] mainly based on the "Report of the Japanese Government to the IAEA Ministerial Conference on Nuclear Safety" [2] published by Nuclear Emergency Response Headquarters in June 2011, three months after the earthquake.Up to 2012 summer, the major investigation boards, including the Japanese Diet, the Japanese Cabinet and TEPCO, published their final reports, in which detailed causes of this accident and several recommendations are assessed from each perspective.In this paper, the authors examine to introduce the lessons learned to be applied to the space safety as findings from these reports.

Pearl Harbor: lessons for the dam safety community

Energy Technology Data Exchange (ETDEWEB)

Martin, T.E. [AMEC Earth and Environmental Ltd., Burnaby, BC (Canada)

2001-10-01

Every good dam safety program must be based on surveillance and emergency response planning. The same principles apply to the gathering of information for military intelligence and the planning of defence tactics. Lessons learned from failure have spurred the advancement of dam engineering. Dam safety experts can benefit from the inadequacies encountered by the military community, with the most famous occurring on December 7, 1941 in Pearl Harbor. Both intelligence gathering and contingency response planning failed miserably. The data was not properly disseminated, interpreted, analysed. The proper response to the situation was not initiated. Human error and failure to communicate are the two main reasons that explain the debacle. The inquiries into the tragedy at Pearl Harbor provided valuable lessons, related to individual and organizational failures, which the authors shared in this presentation. The relevance to dam safety was made. All Federal Bureau of Investigation (FBI) agents must read the lessons drawn from Pearl Harbor, as they have responsibility for dam safety. 4 refs.

Dr. Tulp's Anatomy Lesson by Rembrandt: the third day hypothesis.

Science.gov (United States)

Afek, Arnon; Friedman, Tal; Kugel, Chen; Barshack, Iris; Lurie, Doron J

2009-07-01

An autopsy was an important event in 17th century Holland. Autopsies were held in an 'anatomy theater' and performed according to a fixed protocol that often took up to 3 days to complete. Of the five group portraits painted by Rembrandt over the course of his career, two were anatomy lessons given by Dr. Tulp and Dr. Deyman. An examination of Rembrandt's painting Dr. Tulp's Anatomy Lesson (1632) and an X-ray image of the painting, as compared to other paintings of anatomy lessons from the same period, reveal interesting differences, such as positioning, and light and shadow. Not only was the autopsy not performed according to the usual protocol, but in this painting Rembrandt created a unique dramatic scene in his effort to tell a story. We suggest that Dr. Tulp and Rembrandt "modified" the painting of Dr. Tulp's anatomy lesson to emphasize Dr. Tulp's position as the greatest anatomist of his era--"Vesalius of Amsterdam," and as a way of demonstrating God's greatness by highlighting the hand as a symbol of the most glorious of God's creations.

Main Findings: Lessons to be Learnt

International Nuclear Information System (INIS)

2010-01-01

This section summarizes the main lessons to be learnt from the workshop: 1 - Workshop Methodology: This method of work has proven to be successful. Participants appreciated the high level of interaction with the other colleagues, especially in view of the variety of expertise that was represented at the workshop. The method also affords the participants the opportunity to learn about the status of waste management in the host country, and to come into contact with the main actors. Conversely, the method also affords the host country programme added visibility at the international level. 2 - National Regulations and International Guidance and Bases for Criteria and Regulatory Judgement: There is reasonable consensus amongst national regulations on fundamental regulatory objectives, but much less agreement on the most appropriate criteria. Consensus is nationally and internationally hampered by the lack of common definition of concepts and terms. International guidance is interpreted in different ways in each country. International guidance is rather difficult to interpret, understand and apply. It is important that stakeholders understand the bases for regulatory judgements. 3 - Optimisation: The fundamental goals of optimisation need to be clarified. Optimisation of long-term vs. short-term safety remains problematic. The process of performing optimisation is more important than the numerical or scientific result. A transparent, stepwise and iterative process of decision making is essential for optimisation. The basic, broad rules for decision making and involvement of stakeholders need to be defined in advance. 4 - Technical Indicators for Safe Performance: The relative importance of different safety indicators varies with timescale. There is still much to be done before reaching consensus on the relative importance of different time frames. More discussion is needed on time cut-offs for regulatory compliance. More discussion on the meaning and applicability of

The US Department of Energy (DOE) used several innovative strategies and technologies in conducting the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) activities for the Lower East Fork Poplar Creek (EFPC) Operable Unit (OU) in Oak Ridge, Tennessee. These innovations helped to cost-effectively characterize the 270-ha (670-acre), 23.3-km (14.5-mile) floodplain and to obtain a 400-parts per million (ppm) cleanup level for mercury in soil. Lessons learned during the project involve management, investigation, and risk assessment strategies and techniques. Management lessons learned include (a) how to handle the large OU, (b) how to effectively involve the community in decisions, and (c) how to select a remedy that incorporates the needs of many involved agencies. Investigation lessons learned include (a) how to design an effective sampling strategy for the site, (b) how to cost-effectively analyze a large number of samples, and (c) which of several treatment technologies is best-suited to the site. Risk assessment lessons learned include (a) how to determine an appropriate cleanup level for human health and the environment, (b) how to quantify uncertainty in the human health risk assessment, (c) how to reconcile different solubilities of different mercury species, and (d) how to best conduct the ecological risk assessment. Other CERCLA sites can benefit from lessons learned during this project whether still in the investigative stage or further along in the process. Applying these lessons can substantially reduce costs and make more efficient use of Superfund resources

USING LITERATURE IN GEOGRAPHY LESSONS

Full Text Available Including in a novel information about relief, climate, vegetation, fauna and various aspects of socio-economic life can make literature a real source of geographical information. Using realistic literary works in Geography lessons has multiple benefits, which are not limited only to geographical knowledge. In this paper there are some fragments from literature, suggestions of activities about how to integrate the fragments during Geography lessons and the results of these activities. The activities are from fifth to twelfth grade, passing through a first example of water pollution resulting from a Hercules labour, through the lyricism of the aurora borealis description, through the dramatic life of a refugee from Darfur, through the Dobrudgea winter landscape, through the grey urban landscape of Bucharest in the 90s and so on. Students were put into learning situations that stimulated their creativity, developed communication competencies and enriched their general knowledge.

A Text Mining Approach for Extracting Lessons Learned from Project Documentation: An Illustrative Case Study

Directory of Open Access Journals (Sweden)

Benjamin Matthies

2017-12-01

Full Text Available Lessons learned are important building blocks for continuous learning in project-based organisations. Nonetheless, the practical reality is that lessons learned are often not consistently reused for organisational learning. Two problems are commonly described in this context: the information overload and the lack of procedures and methods for the assessment and implementation of lessons learned. This paper addresses these problems, and appropriate solutions are combined in a systematic lesson learned process. Latent Dirichlet Allocation is presented to solve the first problem. Regarding the second problem, established risk management methods are adapted. The entire lessons learned process will be demonstrated in a practical case study

Experience and lessons learnt from clearance in Germany

International Nuclear Information System (INIS)

Thierfeldt, Stefan

2002-01-01

Clearance is an important corner-stone of waste management in nuclear installations in Germany. It has been practised successfully for around two decades. The importance of clearance can also be judged from the fact that it has been included detailedly in the new German Radiation Protection Ordinance. Currently, there are 19 NPPs and a number of fuel cycle installations in operation in Germany. The main waste quantities, however, arise from the dismantling of NPPs and fuel cycle installations which are currently in decommissioning. As most of the decommissioning projects are targeted for early dismantling instead of safe enclosure, there is already considerable experience with the application of clearance procedures and verification of clearance levels. The German waste management strategy is governed by two options: Clearance of the material (after decontamination and release measurement). After clearance, the material is no longer regarded as radioactive in a legal sense. Final disposal of the material as radioactive waste in a deep geological repository (no near-surface disposal facilities exist or are planned in Germany). A deep geological repository is planned to be operable around 2030. Stefan Thierfeldt described German clearance requirements and lessons learned from their application to decommissioning of power reactors. The great majority of the waste was in fact recycled, although the costs were dominated by the small fraction that had to be disposed of as radioactive waste. Among the lessons learned from the German experience were some revealing insights into the public perception of both clearance and of recycling of material from decommissioning of a nuclear installation

Stereotype Threat Effects on Learning From a Cognitively Demanding Mathematics Lesson.

Science.gov (United States)

Lyons, Emily McLaughlin; Simms, Nina; Begolli, Kreshnik N; Richland, Lindsey E

2018-03-01

Stereotype threat-a situational context in which individuals are concerned about confirming a negative stereotype-is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co-opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability (see Schmader & Beilock, ). We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth-grade students provided either their race or the date before a videotaped, conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated.

Tomkiewicz, W.; Savage, B.; Smith, J.

2008-01-01

Steam Generator Replacement is now complete in Bruce A Units 1 and 2. In each reactor, eight steam generators were replaced; these were the first CANDU steam generator replacements performed anywhere in the world. The plans for replacement were developed in 2004 and 2005, and were summarized in an earlier paper for the CNS Conference held in November, 2006. The present paper briefly summarizes the methodologies and special processes used such as metrology, cutting and welding and heavy lifting. The paper provides an update since the earlier report and focuses on the project achievements to date, such as: - A combination of engineered methodology, laser metrology and precise remote machining led to accurate first time fit-ups of each new replacement steam generator and steam drums - Lessons learned in the first unit led to schedule improvements in the second unit - Dose received was lowest recorded for any steam generator replacement project. The experience gained and lessons learned from Units 1 and 2 will be valuable in planning and executing future replacement steam generator projects. A video was presented

Jacobo, A. C.; Collay, R.; Harris, R. N.; de Silva, L.

2011-12-01

We have formed a link between the Increasing Diversity in Earth Sciences (IDES) program with the Science and Math Investigative Learning Experiences (SMILE) program, both at Oregon State University. The IDES mission is to strengthen the understanding of Earth Sciences and their relevance to society among broad and diverse segments of the population and the SMILE mission is to provide science and math enrichment for underrepresented and other educationally underserved students in grades 4-12. Traditionally, underserved schools do not have enough time or resources to spend on science and mathematics. Furthermore, numerous budget cuts in many Oregon school districts have negatively impacted math and science cirriculum. To combat this trend we have designed suitcase lessons in climate change that can be carried to a number of classrooms. These lesson plans are scientifically rich and economically attractive. These lessons are designed to engage students in math and science through climate change presentations, group discussions, and hands-on activities. Over the past year we have familiarized ourselves with the academic ability of sixth and seventh graders through in-class observation in Salem Oregon. One of the suit case lessons we developed focuses on climate change by exploring the plight of polar bears in the face of diminishing sea ice. Our presentation will report the results of this activity.

Lessons learned and advice from Vietnam war nurses: a qualitative study.

Science.gov (United States)

Scannell-Desch, Elizabeth A

2005-03-01

The aim of this paper is to describe guidance for nurses today from the lessons learned by nurses who served in the Vietnam War. There is little research focusing on nurses' experiences in the Vietnam War. Lessons learned and subsequent advice from nurses who served in Vietnam may be helpful to those serving in current and future wars. A Husserlian phenomenological approach was taken, using interviews with a purposive sample of Registered Nurses who were female, and had served in the United States of America armed forces in Vietnam during the war. Seven theme clusters described the lesson learned and guidance offered by the Vietnam War nurses: advice about journaling, training, caring for yourself, use of support systems, talking about your experiences, understanding the mission, and lack of preparation for war. Much can be learned from the lessons learned and advice given by Vietnam War nurses. These lessons stress that nurses need to take a pro-active role in preparing themselves for deployment to a war zone, and that institutional training for war needs to be intensive and realistic. The environmental, cultural, technological, clinical and psychosocial demands of war nursing need to be comprehensively addressed before nurses deploy to a war.

Highlights: • Discuss the problem of EOPs at the time of Fukushima accident to deal with the prolonged SBO. • Elaborate the potential risk accompanied with the emergency depressurization in the SBO. • Describe a special guideline to cope with Fukushima-like accidents and provide its technical basis. • Point out that Fukushima accident might have been prevented if improved EOPs had been used. • Propose key points and suggestions for improving the EOPs. - Abstract: One of the lessons learned from the Fukushima Daiichi accident is the emergency operating procedures (EOPs) have to be improved. The BWR Owners’ Group revised the emergency procedure guidelines and addressed the lesson learned from the Fukushima Daiichi accident in revision 3 in order to avoid loss of turbine-driven makeup water systems during reactor depressurization. However, the improvement deserves much more attention. The existing EOPs at the time of the accident may not be adequate enough for the prolonged station blackout condition, because resources required for performing the EOPs are vastly unavailable or gradually exhausted. The improved EOPs must not only permit early reactor pressure vessel depressurization, but also address the risk accompanied with the emergency depressurization. For this reason, Taiwan Power Company proposed the Ultimate Response Guideline (URG) to cope with Fukushima-like accidents. The main content of the URG is a two-stage depressurization strategy, namely the controlled depressurization and the emergency depressurization. The technical basis of the two-stage depressurization strategy was discussed in this paper. The effectiveness of the URG was verified by using TRAC/RELAP Advanced Computational Engine (TRACE). Besides, the emergency responses performed by Fukushima Daini nuclear power plant (Fukushima Daini NPP) were found to be very similar to the URG. The consequences of Fukushima Daini NPP somehow demonstrate that the URG is effective for Fukushima

2003-01-01

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

The quality of lesson design is essential to learning effectiveness. Research shows some characteristics of lessons have strong effect on learning which were grouped into "High Impact Practices or HIPs. This research aims to examine the use of HIPs on chemistry lesson design as a part of Teaching Science Strand in Chemistry Concepts course. At the first round of lesson design and implementing in classroom, 14 chemistry pre-services teachers freely selected topics, designed and implemented on their own ideas. The lessons have been reflected by instructors and their peers. High Impact Practices were overtly used as the conceptual framework along with the After-Action Review and Reflection (AARR). The selected High Impact practice in this study consisted of 6 elements: well-designed lesson, vary cognitive demand/academic challenge, students center approach, opportunity of students to reflect by discussion or writing, the assignment of project based learning or task, and the lesson reflects pre-service teachers' Technological Pedagogical Content Knowledge (TPACK). The second round, pre-service teachers were encouraged to explicitly used 6 High Impact Practices in cooperated with literature review specified on focused concepts for bettering designed and implemented lessons. The data were collected from 28 lesson plans and 28 classroom observations to compare and discuss between the first and second lesson and implementation. The results indicated that High Impact Practices effect on the quality of delivered lesson. However, there are some elements that vary on changes which were detailed and discussed in this research article.

Patients and healthcare stakeholders are increasingly becoming engaged in the planning and conduct of biomedical research. However, limited research characterizes this process or its impact. We aimed to characterize patient and stakeholder engagement in the 50 Pilot Projects funded by the Patient-Centered Outcomes Research Institute (PCORI), and identify early contributions and lessons learned. A self-report instrument was completed by researchers between 6 and 12 months following project initiation. Forty-seven principal investigators or their designees (94 % response rate) participated in the study. MAIN MEASURES Self-report of types of stakeholders engaged, stages and levels of engagement, facilitators and barriers to engagement, lessons learned, and contributions from engagement were measured. Most (83 %) reported engaging more than one stakeholder in their project. Among those, the most commonly reported groups were patients (90 %), clinicians (87 %), health system representatives (44 %), caregivers (41 %), and advocacy organizations (41 %). Stakeholders were commonly involved in topic solicitation, question development, study design, and data collection. Many projects engaged stakeholders in data analysis, results interpretation, and dissemination. Commonly reported contributions included changes to project methods, outcomes or goals; improvement of measurement tools; and interpretation of qualitative data. Investigators often identified communication and shared leadership strategies as "critically important" facilitators (53 and 44 % respectively); lack of stakeholder time was the most commonly reported challenge (46 %). Most challenges were only partially resolved. Early lessons learned included the importance of continuous and genuine partnerships, strategic selection of stakeholders, and accommodation of stakeholders' practical needs. PCORI Pilot Projects investigators report engaging a variety of stakeholders across many stages of research, with specific

International R&M/Safety Cooperation Lessons Learned Between NASA and JAXA

Fernandez, Rene; Havenhill, Maria T.; Zampino, Edward J.; Kiefer, Dwayne E.

2013-01-01

Presented are a number of important experiences gained and lessons learned from the collaboration of the National Aeronautics and Space Administration (NASA) and the Japanese Aerospace Exploration Agency (JAXA) on the CoNNeCT (Communications, Navigation, and Networking re-Configurable Testbed) project. Both space agencies worked on the CoNNeCT Project to design, assemble, test, integrate, and launch a communications testbed facility mounted onto the International Space Station (ISS) truss. At the 2012 RAMS, two papers about CoNNeCT were presented: one on Ground Support Equipment Reliability & System Safety, and the other one on combined application of System Safety & Reliability for the flight system. In addition to the logistics challenges present when two organizations are on the opposite side of the world, there is also a language barrier. The language barrier encompasses not only the different alphabet, it encompasses the social interactions; these were addressed by techniques presented in the paper. The differences in interpretation and application of Spaceflight Requirements will be discussed in this paper. Although many, but definitely not all, of JAXA's Spaceflight Requirements were inspired by NASA, there were significant and critically important differences in how they were interpreted and applied. This paper intends to summarize which practices worked and which did not for an international collaborative effort so that future missions may benefit from our experiences. The CoNNeCT flight system has been successfully assembled, integrated, tested, shipped, launched and installed on the ISS without incident. This demonstrates that the steps taken to facilitate international understanding, communication, and coordination were successful and warrant discussion as lessons learned.

Organizational safety factors research lessons learned

Ryan, T.G.

1995-01-01

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

SeaView is an NSF-funded EarthCube Integrative Activity Project working with 5 existing data repositories* to provide oceanographers with highly integrated thematic data collections in user-requested formats. The project has three complementary goals: Supporting Scientists: SeaView targets scientists' need for easy access to data of interest that are ready to import into their preferred tool. Strengthening Repositories: By integrating data from multiple repositories for science use, SeaView is helping the ocean data repositories align their data and processes and make ocean data more accessible and easily integrated. Informing EarthCube (earthcube.org): SeaView's experience as an integration demonstration can inform the larger NSF EarthCube architecture and design effort. The challenges faced in this small-scale effort are informative to geosciences cyberinfrastructure more generally. Here we focus on the lessons learned that may inform other data facilities and integrative architecture projects. (The SeaView data collections will be presented at the Ocean Sciences 2018 meeting.) One example is the importance of shared semantics, with persistent identifiers, for key integration elements across the data sets (e.g. cruise, parameter, and project/program.) These must allow for revision through time and should have an agreed authority or process for resolving conflicts: aligning identifiers and correcting errors were time consuming and often required both deep domain knowledge and "back end" knowledge of the data facilities. Another example is the need for robust provenance, and tools that support automated or semi-automated data transform pipelines that capture provenance. Multiple copies and versions of data are now flowing into repositories, and onward to long-term archives such as NOAA NCEI and umbrella portals such as DataONE. Exact copies can be identified with hashes (for those that have the skills), but it can be painfully difficult to understand the processing

Ahmed, Rafiq

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.

The Use of Lesson Study Combined with Content Representation in the Planning of Physics Lessons During Field Practice to Develop Pedagogical Content Knowledge

Science.gov (United States)

Juhler, Martin Vogt

2016-08-01

Recent research, both internationally and in Norway, has clearly expressed concerns about missing connections between subject-matter knowledge, pedagogical competence and real-life practice in schools. This study addresses this problem within the domain of field practice in teacher education, studying pre-service teachers' planning of a Physics lesson. Two means of intervention were introduced. The first was lesson study, which is a method for planning, carrying out and reflecting on a research lesson in detail with a learner and content-centered focus. This was used in combination with a second means, content representations, which is a systematic tool that connects overall teaching aims with pedagogical prompts. Changes in teaching were assessed through the construct of pedagogical content knowledge (PCK). A deductive coding analysis was carried out for this purpose. Transcripts of pre-service teachers' planning of a Physics lesson were coded into four main PCK categories, which were thereafter divided into 16 PCK sub-categories. The results showed that the intervention affected the pre-service teachers' potential to start developing PCK. First, they focused much more on categories concerning the learners. Second, they focused far more uniformly in all of the four main categories comprising PCK. Consequently, these differences could affect their potential to start developing PCK.

Preservice teachers' use of lesson study in teaching nature of science

Science.gov (United States)

McDowell, Amy Virginia

The purpose of this study was to explore preservice teachers' lived experiences in a lesson study focused on teaching and learning nature of science (NOS). The body of knowledge about shifting pre- and in-service novice NOS understandings is substantial. The focus of science education research is now exploring ways to move these informed NOS understandings into classroom practice (Abd-El-Khalick & Lederman, 2000b). The research questions guiding the study were (a) how do preservice teachers' understandings of NOS shift as a result of the lesson study experience?, and (b) how does the reflective practice that occurs in lesson study influence preservice teachers' transition of NOS tenets into classroom practice? The participants in this study represented a sample of graduate preservice teachers, who were part of a middle and secondary science teaching alternative certification program in a southeastern university. In the first summer semester of this certification program, the participants were immersed in reform based science instruction; a section of which included NOS teachings (INTASC, 2002). In the following semester, participants were placed in a practicum setting; where the exploration of the preservice teachers' teaching of NOS was supported through the modified lesson study framework. Data sources included the Views on Nature of Science-Form B (VNOS-b), interviews, and lesson study portfolios. Analysis of NOS understandings was guided by instruments found in literature associated with the VNOS-b (Lederman et al., 2002) and reflection (Ward & McCotter, 2004). Results showed successful transfer of NOS into classroom practice using the modified lesson study framework, with less success in the deepening of participants' NOS understandings. Of particular significance was that results indicated a deepening of NOS pedagogical content knowledge for those participants functioning at higher levels of reflection. The study's results contributes to two knowledge bases

An Assessment of Need for Instructional Professional Development for Middle School Science Teachers Using Interactive Lessons

Science.gov (United States)

Burton, Amanda

Numerous studies on the impact of interactive lessons on student learning have been conducted, but there has been a lack of professional development (PD) programs at a middle school focusing on ways to incorporate interactive lessons into the science classroom setting. The purpose of this case study was to examine the instructional practices of science teachers to determine whether the need for an interactive lessons approach to teaching students exists. This qualitative case study focused on teachers' perceptions and pedagogy to determine whether the need to use interactive lessons to meet the needs of all students is present. The research question focused on identifying current practices and determining whether a need for interactive lessons is present. Qualitative data were gathered from science teachers at the school through interviews, lesson plans, and observations, all of which were subsequently coded using an interpretative analysis. The results indicated the need for a professional development (PD) program centered on interactive science lessons. Upon completion of the qualitative study, a detailed PD program has been proposed to increase the instructional practices of science teachers to incorporate interactive lessons within the science classroom. Implications for positive social change include improved teaching strategies and lessons that are more student-centered resulting in better understanding and comprehension, as well as performance on state-mandated tests.

Despite growing concern that institutional review boards (IRBs) impose burdensome delays on research, little is known about the time required for IRB review across different types of research. To measure the overall and incremental process times for IRB review as a process of quality improvement. After developing a detailed process flowchart of the IRB review process, 2 analysts abstracted temporal data from the records pertaining to all 103 protocols newly submitted to the IRB at a large urban Veterans Affairs medical center from June 1, 2009, through May 31, 2011. Disagreements were reviewed with the principal investigator to reach consensus. We then compared the review times across review types using analysis of variance and post hoc Scheffé tests after achieving normally distributed data through logarithmic transformation. Calendar days from initial submission to final approval of research protocols. Initial IRB review took 2 to 4 months, with expedited and exempt reviews requiring less time (median [range], 85 [23-631] and 82 [16-437] days, respectively) than full board reviews (median [range], 131 [64-296] days; P = .008). The median time required for credentialing of investigators was 1 day (range, 0-74 days), and review by the research and development committee took a median of 15 days (range, 0-184 days). There were no significant differences in credentialing or research and development times across review types (exempt, expedited, or full board). Of the extreme delays in IRB review, 80.0% were due to investigators' slow responses to requested changes. There were no systematic delays attributable to the information security officer, privacy officer, or IRB chair. Measuring and analyzing review times is a critical first step in establishing a culture and process of continuous quality improvement among IRBs that govern research programs. The review times observed at this IRB are substantially longer than the 60-day target recommended by expert panels

To manage and operate a fusion device and measure meaningful data an accurate and stable time is needed. As a benchmark, we suggest to consider time accuracy as sufficient if it is better than typical data errors or process timescales. This allows to distinguish application domains and chose appropriate time distribution methods. For ASDEX Upgrade a standard NTP method provides Unix time for project and operation management tasks, and a dedicated time system generates and distributes a precise experiment time for physics applications. Applying the benchmark to ASDEX Upgrade shows that physics measurements tagged with experiment time meet the requirements, while correlation of NTP tagged operation data with physics data tagged with experiment time remains problematic. Closer coupling of the two initially free running time systems with daily re-sets was an efficient and satisfactory improvement. For ultimate accuracy and seamless integration, however, continuous adjustment of the experiment time clock frequency to NTP is needed, within frequency variation limits given by the benchmark.

Lessons learned -- NREL Village Power Program

Energy Technology Data Exchange (ETDEWEB)

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.

ELPSA as A Lesson Design Framework

Directory of Open Access Journals (Sweden)

Tom Lowrie

2015-07-01

Full Text Available This paper offers a framework for mathematics lesson design that is consistent with the way we learn about, and discover, most things in life. In addition, the framework provides a structure for identifying how mathematical concepts and understanding are acquired and developed. This framework is called ELPSA and represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. This framework has been used in developing lessons and teacher professional programs in Indonesia since 2012 in cooperation with the World Bank. This paper describes the theory that underlines the framework in general and in relation to each inter-connected component. Two explicit learning sequences for classroom practice are described, associated with Pythagoras theorem and probability. This paper then concludes with recommendations for using ELPSA in various institutional contexts.

Informing future NRT satellite distribution capabilities: Lessons learned from NASA's Land Atmosphere NRT capability for EOS (LANCE)

Science.gov (United States)

Davies, D.; Murphy, K. J.; Michael, K.

2013-12-01

NASA's Land Atmosphere Near real-time Capability for EOS (Earth Observing System) (LANCE) provides data and imagery from Terra, Aqua and Aura satellites in less than 3 hours from satellite observation, to meet the needs of the near real-time (NRT) applications community. This article describes the architecture of the LANCE and outlines the modifications made to achieve the 3-hour latency requirement with a view to informing future NRT satellite distribution capabilities. It also describes how latency is determined. LANCE is a distributed system that builds on the existing EOS Data and Information System (EOSDIS) capabilities. To achieve the NRT latency requirement, many components of the EOS satellite operations, ground and science processing systems have been made more efficient without compromising the quality of science data processing. The EOS Data and Operations System (EDOS) processes the NRT stream with higher priority than the science data stream in order to minimize latency. In addition to expediting transfer times, the key difference between the NRT Level 0 products and those for standard science processing is the data used to determine the precise location and tilt of the satellite. Standard products use definitive geo-location (attitude and ephemeris) data provided daily, whereas NRT products use predicted geo-location provided by the instrument Global Positioning System (GPS) or approximation of navigational data (depending on platform). Level 0 data are processed in to higher-level products at designated Science Investigator-led Processing Systems (SIPS). The processes used by LANCE have been streamlined and adapted to work with datasets as soon as they are downlinked from satellites or transmitted from ground stations. Level 2 products that require ancillary data have modified production rules to relax the requirements for ancillary data so reducing processing times. Looking to the future, experience gained from LANCE can provide valuable lessons on

Revision of the AESJ Standard for Seismic Probabilistic Risk Assessment (PRA). Updating requirements based on the lessons learned from the Fukushima Dai-ichi NPP Accidents (3). Fragility evaluation and outline of the updated points

Yamaguchi, Akira; Nakamura, Susumu; Mihara, Yoshinori

2014-01-01

Lessons learned from Great East Japan earthquake and other new findings had been accumulated on the fragility evaluation of buildings and components. And also new analysis and evaluation method had been proposed with the advancement of recent analysis and evaluation technology. These were reflected in revision of the AESJ Standard for Seismic Probabilistic Risk Assessment (PRA). Scope of the fragility evaluation were extended to all equipment on the site, severe accident management equipment including portable equipment and earthquake concomitant incident (such as tsunami) countermeasure equipment. This article described outlines of updating points of the fragility evaluation of the AESJ Standard for Seismic PRA; (1) requirements for seismic induced other risk evaluations such as fire, inundation and tsunami, (2) simulation technology based on recent findings such as three dimensional responses of buildings / structures and its effect on equipment, (3) requirements of the fragility evaluation for various failure mode of several equipment such as severe accident management equipment, fine failure mode of buildings / structures, failures of equipment related with earthquake concomitant incidents (embankment and seawall) and spent fuel pool, and (4) requirements for the fragility evaluation of aftershocks and soil deformation due to fault displacement.

Strategic Program Planning Lessons Learned In Developing The Long-Term Stewardship Science and Technology Roadmap

Energy Technology Data Exchange (ETDEWEB)

Dixon, B.W.; Hanson, D.J.; Matthern, G.E.

2003-04-24

Technology roadmapping is a strategic planning method used by companies to identify and plan the development of technologies necessary for new products. The U.S. Department of Energy's Office of Environmental Management has used this same method to refine requirements and identify knowledge and tools needed for completion of defined missions. This paper describes the process of applying roadmapping to clarify mission requirements and identify enhancing technologies for the Long-Term Stewardship (LTS) of polluted sites after site cleanup has been completed. The nature of some contamination problems is such that full cleanup is not achievable with current technologies and some residual hazards remain. LTS maintains engineered contaminant barriers and land use restriction controls, and monitors residual contaminants until they no longer pose a risk to the public or the environment. Roadmapping was used to clarify the breadth of the LTS mission, to identify capability enhancements needed to improve mission effectiveness and efficiency, and to chart out the research and development efforts to provide those enhancements. This paper is a case study of the application of roadmapping for program planning and technical risk management. Differences between the planned and actual application of the roadmapping process are presented along with lessons learned. Both the process used and lessons learned should be of interest for anyone contemplating a similar technology based planning effort.

Energy efficiency and renewable energies: first lessons learned from AFD and FFEM funding

International Nuclear Information System (INIS)

Ries, Alain; Dubus, Koulm; Naudet, Jean David

2008-04-01

The French Agency for Development (AFD) has been always more involved in projects dealing with issues related to global warming, and more particularly in projects aiming at developing energy efficiency and renewable energies, these projects involved different expertises (energy, urban planning, transports, agriculture, and so on). In order to highlight lessons learned from these diversity of projects and interventions, this report first proposes an analysis of these projects related to energy efficiency and renewable energies in terms of concerned sectors, of intervener, of funding type, and of evolution in time. Then, the authors highlight lessons learned in terms of project starting conditions (national framework, funding, technical abilities, social and environmental factors), in terms of funding conditions for these projects (concessional financing, specialised credit lines), and in terms of climatic impact assessment and of criteria of project selection (practices and reductions of greenhouse gas emissions, improvement of the climatic impact for project financed by the AFD)

A tale of two campuses: Lessons learned in establishing a satellite campus.

2018-05-01

"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity." The opening line of Dickens's A Tale of Two Cities could easily be the dramatic opening line of a summary of the establishment of a satellite medical school campus in Manitoba. Reflection on my last four years as associate dean reveals that most of the descriptors in that famous sentence at one time or another were apropos. This brief essay will relate the experiences of the last four years and some of the lessons learned along the way.

Lessons from Queer Bioethics: A Response to Timothy F. Murphy.

Science.gov (United States)

Richie, Cristina

2016-06-01

'Bioethics still has important work to do in helping to secure status equality for LGBT people' writes Timothy F. Murphy in a recent Bioethics editorial. The focus of his piece, however, is much narrower than human rights, medical care for LGBT people, or ending the HIV/AIDS pandemic. Rather, he is primarily concerned with sexuality and gender identity, and the medical intersections thereof (i.e. DSM diagnosis; access to SrS or ARTs). It is the objective of this response to provide an alternate account of bioethics from a Queer perspective. I will situate Queer bioethics within Queer studies, and offer three 'lessons' that bioethics can derive from this perspective. These are not definitive rules for Queer bioethics, since it is a field which fundamentally opposes categorizations, favoring pastiche over principles. These lessons are exploratory examples, which both complement and contradict LGBT bioethics. My latter two lessons - on environmental bioethics and disability - overlap with some of Murphy's concerns, as well as other conceptions of LGBT bioethics. However, the first lesson takes an antithetical stance to Murphy's primary focus by resisting all forms of heteroconformity and disavowing reproduction as consonant with Queer objectives and theory. The first lesson, which doubles as a primer in Queer theory, does heavy philosophical lifting for the remainder of the essay. This response to Timothy F. Murphy, whose work is certainly a legacy in bioethics, reveals the multiplicity of discourses in LGBT/Queer studies, many of which are advantageous - even essential - to other disciplines like bioethics. © 2016 John Wiley & Sons Ltd.

Crisis communication. Lessons from 9/11.

Science.gov (United States)

Argenti, Paul

2002-12-01

The sheer enormity of last year's terrorist attacks on the World Trade Center and the Pentagon gave new meaning to the term "crisis management." Suddenly, companies near Ground Zero, as well as those more than a thousand miles away, needed a plan. Because the disasters disrupted established channels not only between businesses and customers but between businesses and employees, internal crisis-communications strategies that could be quickly implemented became a key responsibility of top management. Without these strategies, employees' trauma and confusion might have immobilized their firms and set their customers adrift. In this article, executives from a range of industries talk about how their companies, including Morgan Stanley, Oppenheimer Funds, American Airlines, Verizon, the New York Times, Dell, and Starbucks, went about restoring operations and morale. From his interviews with these individuals, author and management professor Paul Argenti was able to distill a number of lessons, each of which, he says, may "serve as guideposts for any company facing a crisis that undermines its employees' composure, confidence, or concentration." His advice to senior executives includes: Maintain high levels of visibility, so that employees are certain of top management's command of the situation and concern; establish contingency communication channels and work sites; strive to keep employees focused on the business itself, because a sense of usefulness enhances morale and good morale enhances usefulness; and ensure that employees have absorbed the firm's values, which will guide them as they cope with the unpredictable. The most forward-thinking leaders realize that managing a crisis-communications program requires the same dedication and resources they give to other dimensions of their business. More important, they realize that their employees always come first.

In Before It''s Too Late: A Report to the Nation from the National Commission on Mathematics and Science Teaching for the 21st Century (2000) in the US, the authors quote from James Stigler''s conclusions from various videotape research studies of mathematics teaching: "The key to long-term improvement [in teaching] is to figure out how to generate, accumulate, and share professional knowledge". Japanese Lesson Study has proved to be one successful means. This book supports the growing movement of lesson study to improve the quality of mathematics education from the original viewpoints of Japanese educators who have been engaging in lesson study in mathematics for professional development and curriculum implementation. This book also illustrates several projects related to lesson study in other countries.

Vacuum performances and lessons for 2012

Baglin, V.; Bregliozzi, G.; Jimenez, J.M.; Lanza, G.

2012-01-01

During the LHC run 2011, a tremendous progress has been made towards the machine operation with design parameters. In the same time, the run confirmed the sensitivity of the beam vacuum system to the machine parameters. As expected, a successful scrubbing period allowed mitigating the effects of the electron cloud giving room to an entire filling of the ring with 50 ns beams. In parallel issues such as the impact of the beam screen regulation, pressures spikes and local outgassing were observed during the year. On-line mitigations and immediate compensatory measures implemented during the winter technical stop are reviewed together with their efficiencies. All unexpected pressure behaviours observed during 2011 are understood. The expected limitations while waiting for LS1 consolidation or when running with 25 ns beams are addressed. Lessons for 2012 are discussed. (authors)

Lessons learned from completed evaluation reviews (1983 to mid-1993). Special evaluation review

International Nuclear Information System (INIS)

1993-01-01

With this in mind, the Agency in 1983 set up in the Department of Technical Co-operation an Evaluation Unit (upgraded to Section rank in 1986), to assist already existing self-evaluation efforts through a more systematic and independent approach and thus provide senior management with the information required for more efficient and effective programme planning and implementation. A first analysis of the lessons learned through technical co-operation evaluation was carried out after five years, in mid-1988. It included both lessons learned with regard to the procedures and components of the programme, in general, as well as the findings specific to individual projects or groups of projects, and reported on the resulting administrative changes introduced by the Agency with a view to improving the programme. The current review, covering the second five-year period, from mid-1988 to mid-1993, continued along the same lines, while also illustrating the changing pattern in the work of the Evaluation Section itself. In order to present a full picture of the activities and results of ten years of TC evaluation, this report combines the results of both reviews
